<p>Say you create a form using ASP.NET MVC that has a dynamic number of form elements.</p>
<p>For instance, you need a checkbox for each product, and the number of products changes day by day.</p>
<p>How would you handle that form data being posted back to the controller? You can't set up parameters on the action method because you don't know how many form values are going to be coming back.</p>

<p>How do I pull out the filename from a full path using regular expressions in C#?</p>
<p>Say I have the full path <code>C:\CoolDirectory\CoolSubdirectory\CoolFile.txt</code>.</p>
<p>How do I get out CoolFile.txt using the .NET flavor of regular expressions? I'm not really good with regular expressions, and my RegEx buddy and me couldn't figure this one out.</p>
<p>Also, in the course of trying to solve this problem, I realized that I can just use <code>System.IO.Path.GetFileName</code>, but the fact that I couldn't figure out the regular expression is just making me unhappy and it's going to bother me until I know what the answer is.</p>

<p>I've got two directories containing ~20 GB of music files (mostly mp3, some ogg), and I would like to detect all duplicate songs. There are two complicating factors:</p>
<ol>
<li>A song may have different filenames in the two directories.</li>
<li>Two files containing the same song may have different ID3 tags and thus have different checksums.</li>
</ol>
<p>What is a good approach to solving this?</p>

<pre><code>SqlConnection connection = new SqlConnection(FROM_CONFIGURATION)
SqlCommand command = new SqlCommand("SomeSQL", connection);
connection.Open();
command.ExecuteNonQuery();
command.Dispose();
connection.Dispose();
</code></pre>
<p>It is recommended that the code above should include try/catch (or using) so that if an exception is thrown, all resources are disposed properly.</p>
<p>But if you have to worry about disposing stuff manually, then what's the point of the GC?! Isn't GC there to take care of this for the coder?</p>

<p>If A references assembly B 1.1 and C, and C references B 1.2, how do you avoid assembly conflicts?</p>
<p>I nievely assumed C's references would be encapsulated away and would not cause any problems, but it appears all the dll's are copied to the bin, which is where the problem occurs.</p>
<p>I understand the two ways around this are to use the GAC or assembly bindings? The GAC doesn't seem like the best approach to me, as I don't like assuming dlls will be there, I prefer to reference dlls from a lib directory in my solution.</p>
<p>Where as assembly bindings don't seem robust to me, what if one version of the assembly has functionality that the other doesn't, will this not produce problems?</p>
<hr>
<p>In my case its because I'm using a 3rd party dll uses a older version of nHibernate, than I'm using myself.</p>

<p>At a previous employer, we were writing binary messages that had to go "over the wire" to other computers. Each message had a standard header something like:</p>
<pre><code>class Header
{
int type;
int payloadLength;
};
</code></pre>
<p>All of the data was contiguous (header, immediately followed by data). We wanted to get to the payload given that we had a pointer to a header. Traditionally, you might say something like:</p>
<pre><code>char* Header::GetPayload()
{
return ((char*) &payloadLength) + sizeof(payloadLength);
}
</code></pre>
<p>or even:</p>
<pre><code>char* Header::GetPayload()
{
return ((char*) this) + sizeof(Header);
}
</code></pre>
<p>That seemed kind of verbose, so I came up with:</p>
<pre><code>char* Header::GetPayload()
{
return (char*) &this[1];
}
</code></pre>
<p>It seems rather disturbing at first, possibly too odd to use -- but very compact.
There was a lot of debate on whether it was brilliant or an abomination. </p>
<p>So which is it - Crime against coding, or nice solution? Have you ever had a similar trade-off?</p>
<p>-Update:</p>
<p>We did try the zero sized array, but at the time, compilers gave warnings.
We eventually went to the inhertited technique: Message derives from Header.
It works great in practice, but in priciple you are saying a message IsA Header - which seems a little awkward.</p>

<p>Which Oracle database role will allow a user to select from a table in another schema without specifying the schema identifier?
i.e., as user A- Grant select on A.table to user B;
B can then- "Select * from table" without specifying the 'A'.
One of our databases allows this, the other returns a 'table or view does not exist' error. </p>

<p>I have a requirement to install multiple web setup projects (using VS2005 and ASP.Net/C#) into the same virtual folder. The projects share some assembly references (the file systems are all structured to use the same 'bin' folder), making deployment of changes to those assemblies problematic since the MS installer will only overwrite assemblies if the currently installed version is older than the one in the MSI.</p>
<p>I'm not suggesting that the pessimistic installation scheme is wrong - only that it creates a problem in the environment I've been given to work with. Since there are a sizable number of common assemblies and a significant number of developers who might change a common assembly but forget to update its version number, trying to manage versioning manually will eventually lead to massive confusion at install time.</p>
<p>On the flip side of this issue, it's also important not to spontaneously update version numbers and replace <em>all</em> common assemblies with <em>every</em> install, since that could (temporarily at least) obscure cases where actual changes were made.</p>
<p>That said, what I'm looking for is a means to update assembly version information (preferably using MSBuild) only in cases where the assembly constituents (code modules, resources etc) has/have actually changed.</p>
<p>I've found a few references that are at least partially pertinent <a href="http://code.msdn.microsoft.com/AssemblyInfoTaskvers/Release/ProjectReleases.aspx?ReleaseId=232" rel="noreferrer" title="here">here </a> (AssemblyInfo task on MSDN) and <a href="http://social.msdn.microsoft.com/Forums/en-US/msbuild/thread/94054d89-ba19-4658-9e4e-ce7d8ff4dea3/" rel="noreferrer" title="here">here</a> (looks similar to what I need, but more than two years old and without a clear solution).</p>
<p>My team also uses TFS version control, so an automated solution should probably include a means by which the AssebmlyInfo can be checked out/in during the build.</p>
<p>Any help would be much appreciated.</p>
<p>Thanks in advance.</p>

<p>I have a simple query like this:</p>
<pre><code>select * from mytable where id > 8
</code></pre>
<p>I want to make the 8 a variable. There's some syntax like </p>
<pre><code>declare @myvar int
myvar = 8
</code></pre>
<p>but I don't know the exact syntax.</p>
<p>What is it?</p>
<p>Thanks!</p>

<p>Even a simple <a href="http://en.wikipedia.org/wiki/Notepad_%28software%29" rel="noreferrer">Notepad</a> application in C# consumes megabytes of RAM as seen in the task manager. On minimizing the application the memory size in the task manager goes down considerably and is back up when the application is maximized.</p>
<p>I read somewhere that the .NET process reserves a lot of memory for runtime allocation in advance. That's why .NET applications have a larger memory footprint to start with. But this memory can be released using Win32 API calls. A trade-off is that runtime allocation becomes slow - is that true?</p>

<p>I am using the following code:</p>
<pre><code><?php
$stock = $_GET[s]; //returns stock ticker symbol eg GOOG or YHOO
$first = $stock[0];
$url = "http://biz.yahoo.com/research/earncal/".$first."/".$stock.".html";
$data = file_get_contents($url);
$r_header = '/Prev. Week(.+?)Next Week/';
$r_date = '/\<b\>(.+?)\<\/b\>/';
preg_match($r_header,$data,$header);
preg_match($r_date, $header[1], $date);
echo $date[1];
?>
</code></pre>
<p>I've checked the regular expressions <a href="http://www.quanetic.com/regex.php" rel="nofollow noreferrer">here</a> and they appear to be valid. If I check just $url or $data they come out correctly and if I print $data and check the source the code that I'm looking for to use in the regex is in there. If you're interested in checking anything, an example of a proper URL would be <a href="http://biz.yahoo.com/research/earncal/g/goog.html" rel="nofollow noreferrer">http://biz.yahoo.com/research/earncal/g/goog.html</a></p>
<p>I've tried everything I could think of, including both var_dump($header) and var_dump($date), both of which return empty arrays.</p>
<p>I have been able to create other regular expressions that works. For instance, the following correctly returns "Earnings":</p>
<pre><code>$r_header = '/Company (.+?) Calendar/';
preg_match($r_header,$data,$header);
echo $header[1];
</code></pre>
<p>I am going nuts trying to figure out why this isn't working. Any help would be awesome. Thanks.</p>

<p>I am trying to use page methods in my asp.net page. I have enable page methods set to true on the script manager, the webmethod attribute defined on the method, the function is public static string, I know the function works because when I run it from my code behind it generates the expected result, but when I call it via page method in my result function the result is always alerted as undefined. If I use fiddler it doesn't even look like there is additional traffic or a new request created. I'm running the site on port 82 if that makes a difference. I'm at a loss here. Can someone give me some pointers?</p>

<p>Quite simple really:</p>
<pre><code>var req:URLRequest=new URLRequest();
req.url="http://somesite.com";
var header:URLRequestHeader=new URLRequestHeader("my-bespoke-header","1");
req.requestHeaders.push(header);
req.method=URLRequestMethod.GET;
stream.load(req);
</code></pre>
<p>Yet, if I inspect the traffic with WireShark, the <code>my-bespoke-header</code> is not being sent. If I change to <code>URLRequestMethod.POST</code> and append some data to <code>req.data</code>, then the header is sent, but the receiving application requires a GET not a POST. </p>
<p>The documentation mentions a blacklist of headers that will not get sent. <code>my-bespoke-header</code> is not one of these. It's possibly worth mentioning that the originating request is from a different port on the same domain. Nothing is reported in the policyfile log, so it seems unlikely, but is this something that can be remedied by force loading a crossdomain.xml with a <code>allow-http-request-headers-from</code> despite the fact that this is not a crossdomain issue? Or is it simply an undocumented feature of the Flash Player that it can only send custom headers with a POST request?</p>

<p>In an effort to satisfy "The Joel Test" question #2 "Can you make a build in one step?", I'm trying to complete a release candidate build script with the creation of a CD iso from the collection of files gathered and generated by the installer creator.</p>
<p>There seem to be many good tools (many free) out there that will create ISOs, but I need to find one that can be run at the windows command line so I can integrate it into the NAnt build script that's fired off by Cruise Control.</p>
<p>Build environment is:</p>
<ul>
<li>Windows Server 2003</li>
<li>.NET 1.1 - 3.5 (application we're creating is built on 2.0)</li>
<li>NullSoft installer (NSIS)</li>
<li>CruiseControl.net</li>
<li>NAnt</li>
</ul>
<p>I've been googling around, but no luck yet.</p>
<p>Anyone have a recommendation?</p>

<p>This may not be the correct way to use controllers, but I did notice this problem and hadn't figured out a way to correct it. </p>
<pre><code>public JsonResult SomeControllerAction() {
//The current method has the HttpContext just fine
bool currentIsNotNull = (this.HttpContext == null); //which is false
//creating a new instance of another controller
SomeOtherController controller = new SomeOtherController();
bool isNull = (controller.HttpContext == null); // which is true
//The actual HttpContext is fine in both
bool notNull = (System.Web.HttpContext.Current == null); // which is false
}
</code></pre>
<p>I've noticed that the HttpContext on a Controller isn't the "actual" HttpContext that you would find in System.Web.HttpContext.Current. </p>
<p>Is there some way to manually populate the HttpContextBase on a Controller? Or a better way to create an instance of a Controller?</p>

<p>I'm trying to have a new layer appear above existing content on my site when a link/button is clicked. I am using jquery - but the code I have doesn't seem to work as expected.</p>
<p>Here is what I have:</p>
<pre><code> $(document).ready(function(){
$("#button").click(function () {
$("#showme").insertAfter("#bodytag")
$("#showme").fadeIn(2000);
});
</code></pre>
<p>});</p>
<p>The effect I'm after is to have <code><div id="showme">...</div></code> appear directly after the #bodytag. <code><div id="showme">...</div></code> has a z-index higher than anything else on the site, so it should just appear above the content directly after the #bodytag.</p>
<p>Thanks for the assistance.</p>

<p>Building a java application that supports different Locales, but would like to customize the <code>DateFormat</code> display beyond what is available between <code>FULL</code>, <code>LONG</code>, <code>MEDIUM</code>, and <code>SHORT</code> DateFormat options. Would like to do things like place a character between the date and time components of a <code>DateFormat.getDateTimeFormat()</code>, lowercase the AM/PM, etc, at least for english.</p>
<p>can think of 3 ways to do it:</p>
<p>1) if locale is english, use my custom format string on a <code>new SimpleDateFormat</code> object.</p>
<p>2) modify the default format strings for existing locales</p>
<p>3) create a new locale variant that specifies the format strings I want</p>
<p>Can't figure out how to do 2 or 3 (or if it's even possible), and would rather not do 1... has anyone dealt with anything like this before?</p>
<p>also, seems like 2 or 3 would be necessary for lowercasing the AM/PM ? (Specifiying the AmPmMarkers resource for the locale's dateformat settings)</p>

<p>I have been trying to strip out some data from HTML files. I have the logic coded to get the right cells. Now I am struggling to get the actual contents of the 'cell':</p>
<p>here is my HTML snippet:</p>
<p>headerRows[0][10].contents</p>
<pre><code> [<font size="+0"><font face="serif" size="1"><b>Apples Produced</b><font size="3">
</font></font></font>]
</code></pre>
<p>Note that this is a list item from Python [].</p>
<p>I need the value Apples Produced but can't get to it.</p>
<p>Any suggestions would be appreciated</p>
<p>Suggestions on a good book that explains this would earn my eternal gratitude</p>
<hr>
<p>Thanks for that answer. However-isn't there a more general answer. What happens if my cell doesn't have a bold attribute</p>
<p>say it is:</p>
<pre><code> [<font size="+0"><font face="serif" size="1"><I>Apples Produced</I><font size="3">
</font></font></font>]
</code></pre>
<p><I>Apples Produced</I><br>
</p>
<p>I am trying to learn to read/understand the documentation and your response will help</p>
<p>I really appreciate this help. The best thing about these answers is that it is a lot easier to generalize from them then I have been able to do so from the BeautifulSoup documentation. I learned to program in the Fortran era and now I am learning python and I am amazed at its power - BeautifulSoup is an example. Making a coherent whole of the documentation is tough for me.</p>
<p>Cheers</p>

<p>I'm trying to determine the reason for a stalled process on Linux. It's a telecom application, running under fairly heavy load. There is a separate process for each of 8 T1 spans. Every so often, one of the processes will get very unresponsive - up to maybe 50 seconds before an event is noted in the normally very busy process's log.</p>
<p>It is likely some system resource that runs short. The obvious thing - CPU usage - looks to be OK. </p>
<p>Which linux utilities might be best for catching and analyzing this sort of thing, and be as unobtrusive about it as possible, as this is a highly loaded system? It would need to be processes rather than system oriented, it would seem. Maybe ongoing monitoring of /proc/pid/XX? Top wouldn't seem to be too useful here.</p>

<p>I've got a really simple rails question here but I can't seem to find the answer anywhere. I guess some of the problems stem from me following a tutorial for Rails 1.2 with Rails 2.1. Anyway..</p>
<p>I'm writing a blog system and I'm implementing the comments bit. I have comments displaying fine once I've created them using script/console, but getting the comment form itself working is the hard bit.</p>
<p>In posts_controller.rb I have</p>
<pre><code> def comment
Post.find(params[:id]).comments.create(params[:comment])
flash[:notice] = "Added comment"
#render :action => show
redirect_to :action => show
end
</code></pre>
<p>and in show.html.erb (the view) I have</p>
<pre><code><%= form_tag :action => "comment", :id => @post %>
<%= text_area "comment", "body" %><br>
<%= submit_tag "Post Comment" %>
</code></pre>
<p>When I submit the form it tries to go to the urb /posts/comment/1 which is obviously incorrect, and it complains that it can't find a template. Obviously I don't want a template there because I've told it to redirect to the show action because I want it to just re-display the post's show page, with the new comment there.</p>
<p>I've tried both the commented out line (render :action => show) and the redirect_to line, and neither seem to do anything at all.</p>
<p>I'm sure I'm missing something simple, but what is it?</p>

<p>I've just started learning linq and lambda expressions, and they seem to be a good fit for finding duplicates in a complex object collection, but I'm getting a little confused and hope someone can help put me back on the path to happy coding.</p>
<p>My object is structured like list.list.uniqueCustomerIdentifier</p>
<p>I need to ensure there are no duplicate uniqueCustomerIdentifier with in the entire complex object. If there are duplicates, I need to identify which are duplicated and return a list of the duplicates.</p>

<p>My question is quite relevant to <a href="https://stackoverflow.com/questions/42785/how-do-you-retrofit-unit-tests-into-a-code-base">something asked before</a> but I need some practical advice.</p>
<p>I have "Working effectively with legacy code" in my hands and I 'm using advice from the book as I read it in the project I 'm working on. The project is a C++ application that consists of a few libraries but the major portion of the code is compiled to a single executable. I 'm using googletest for adding unit tests to existing code when I have to touch something.</p>
<p>My problem is how can I setup my build process so I can build my unit tests since there are two different executables that need to share code while I am not able to extract the code from my "under test" application to a library. Right now I have made my build process for the application that holds the unit tests link against the object files generated from the build process of the main application but I really dislike it. Are there any suggestions?</p>

<p>Which industry-class database has the most <strong>unique</strong> features? (with "unique" meaning that no other RDBMS has them)</p>
<p>I think my choice here is Oracle 11g:</p>
<ol>
<li>Flashback query (you can estract data as it was a moment in the past)</li>
<li>ASM - automatic storage management</li>
<li>Native code compilation of stored procedures</li>
<li>Audit features (tracing everything, from logins to statements)</li>
</ol>
<p>and many others.</p>

<p>I get to dust off my VBScript hat and write some classic ASP to query a SQL Server 2000 database.</p>
<p>Here's the scenario:</p>
<ul>
<li>I have two <em>datetime</em> fields called <strong>fieldA</strong> and <strong>fieldB</strong>.</li>
<li><strong>fieldB</strong> will never have a year value that's greater than the year of <strong>fieldA</strong></li>
<li>It <strong>is</strong> possible the that two fields will have the same year.</li>
</ul>
<p>What I want is all records where <strong>fieldA</strong> >= <strong>fieldB</strong>, <em>independent of the year</em>. Just pretend that each field is just a month & day.</p>
<p>How can I get this? My knowledge of T-SQL date/time functions is spotty at best.</p>

<p>Question: </p>
<pre><code>((lambda (x y) (x y)) (lambda (x) (* x x)) (* 3 3))
</code></pre>
<p>This was #1 on the midterm, I put "81 9" he thought I forgot to cross one out lawl, so I cross out 81, and he goes aww. Anyways, I dont understand why it's 81.</p>
<p>I understand why <code>(lambda (x) (* x x)) (* 3 3) = 81</code>, but the first lambda I dont understand what the x and y values are there, and what the <code>[body] (x y)</code> does.</p>
<p>So I was hoping someone could explain to me why the first part doesn't seem like it does anything.</p>

<p>Aspell-net is a port of the GNU Aspell for .Net Framework. The library itself is open source, and is under the LGPL license, but the english dictionary for aspell is mentioned as copyrighted on the sourceforge.net project home page at <a href="http://aspell-net.sourceforge.net/" rel="nofollow noreferrer">http://aspell-net.sourceforge.net/</a></p>
<p>Did any of you guys use aspell-net before? and what license did you release your software under? The project I work on is a commercial one, and do you guys forsee any problem? Should I pay for the aspell english dictionary?</p>
<p>Thanks.</p>

<p>Simple question that keeps bugging me.</p>
<p>Should I HTML encode user input right away and store the encoded contents in the database, or should I store the raw values and HTML encode when displaying?</p>
<p>Storing encoded data greatly reduces the risk of a developer forgetting to encode the data when it's being displayed. However, storing the encoded data will make datamining somewhat more cumbersome and it will take up a bit more space, even though that's usually a non-issue.</p>

<p>My company requires me to use Outlook for my E-mail. Outlook does virtually nothing the way I want to do it and it frustrates me greatly. (I'm not trying to start a flame war here, it must do exactly what thousands of CEO's want it to do, but I'm not a CEO.)</p>
<p>I would like to be able to automatically extract the thousands of E-mails and attachments currently in my Outlook account and save them in my own alternative storage format where I can easily search them and organize them the way I want. (I'm not requesting suggestions for the new format.)</p>
<p>Maybe some nice open source program already can do this... that would be great. Please let me know.</p>
<p>Otherwise, <b>how can I obtain the message content and the attachments without going through the huge collection manually?</b> Even if I could only get the message content and the names of the attachments, that would be sufficient. Is there documentation of the Outlook mail storage format? Is there a way to query Outlook for the data?</p>
<p>Maybe there is an alternative approach I haven't considered?</p>
<p>My preferred language to do this is C#, but I can use others if needed.</p>

<p>Is there a way to Invoke an overloaded method using reflection in .NET (2.0). I have an application that dynamically instantiates classes that have been derived from a common base class. For compatibility purposes, this base class contains 2 methods of the same name, one with parameters, and one without. I need to call the parameterless method via the Invoke method. Right now, all I get is an error telling me that I'm trying to call an ambiguous method.</p>
<p>Yes, I <em>could</em> just cast the object as an instance of my base class and call the method I need. Eventually that <em>will</em> happen, but right now, internal complications will not allow it.</p>
<p>Any help would be great! Thanks.</p>

<p>I'm writing a small application in VB.NET and I would like some of the classes to be able to write themselves out to XML to serve as a "save" feature. I have seen XSD files used to generate VB classes that can serialize themselves into and out of XML very easily. How would I do this if I do have any pre-existing XML format that I need to conform to as I'm just creating the classes myself?</p>

<p>The people doing the translation will not have access to Visual Studio and the likely easiest tool is Excel. If we use Excel or even export to CSV, we need to be able to import to move to .resx files. So, what is the best method for this?</p>
<p>I am aware of this question, <a href="https://stackoverflow.com/questions/198772/convert-a-visual-studio-resource-file-to-a-text-file">Convert a Visual Studio resource file to a text file?</a> already and the use of Resx Editor but an easier solution would be preferred.</p>

<p>I have been reading the <a href="http://msdn.microsoft.com/en-us/library/ms997565.aspx" rel="nofollow noreferrer">MSDN</a> documentation on subclassing and I have been successful in handling events in a subclass</p>
<p>My issue is with passing messages back to the original WndProc.</p>
<p>As an example, if I have a window, with a sub-classed groupbox control and a button as a child of that groupbox, I want to handle the button event in the original window procedure, not the subclassed groupbox procedure.</p>
<p>Essentially, I want an empty subclass procedure:</p>
<pre><code>LRESULT FAR PASCAL SubClassFunc(HWND hwnd,
UINT uMsg,
WPARAM wParam,
LPARAM lParam)
{
return CallWindowProc(oldProc, hwnd, uMsg, wParam, lParam);
}
</code></pre>
<p>Where oldProc is:</p>
<pre><code>FARPROC oldProc = (FARPROC)SetClassLong(group_box, GCL_WDPROC, (DWORD)SubCLassFunc);
</code></pre>
<p>And where the window and groupbox and button are:</p>
<pre><code>HWND window = CreateWindowEx(
WS_EX_WINDOWEDGE,
appname,
TEXT("Subclass Test"),
WS_VISIBLE |WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT,
CW_USEDEFAULT,
300,
400,
NULL,
NULL,
hInstance,
0);
HWND group_box = CreateWindowEx(
0,
TEXT("BUTTON"),
TEXT("Group Box"),
WS_CHILD | WS_VISIBLE | BS_GROUPBOX,
8,
8,
275,
350,
window,
NULL,
hInstance,
0);
HWND push_button = CreateWindowEx(
0,
TEXT("BUTTON"),
TEXT("Push Button"),
WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON | BS_VCENTER,
50,
100,
100,
25,
group_box,
(HMENU)PUSH_BUTTON,
hInstance,
0);
</code></pre>
<p>I can handle the button events in the SubClassFunc, but what I want to do is pass them back to the window WndProc. It seems that CallWindowProc isn't doing this, or I may be totally wrong in how CallWindowProc works.</p>

<p>We have a product but we are doing some rebranding so we need to be able to build and maintain two versions. I used resource files combined with some #if stuff to solve the strings, images, and whatever else, but the program icon is giving me trouble. I couldn't figure it out from msdn or a google search. Thanks!</p>

<p>Say I need some very special multiplication operator. It may be implemented in following macro:</p>
<pre><code>macro @<<!(op1, op2)
{
<[ ( $op1 * $op2 ) ]>
}
</code></pre>
<p>And I can use it like</p>
<pre><code>def val = 2 <<! 3
</code></pre>
<p>And its work.</p>
<p>But what I really want is some 'english'-like operator for the DSL Im developing now:</p>
<pre><code>macro @multiply(op1, op2)
{
<[ ( $op1 * $op2 ) ]>
}
</code></pre>
<p>and if I try to use it like</p>
<pre><code>def val = 2 multiply 3
</code></pre>
<p>compiler fails with 'expected ;' error</p>
<p>What is the problem? How can I implement this infix-format macro?</p>

<p>I want to know how to use variables for objects and function names in Python. In PHP, you can do this:</p>
<pre><code>$className = "MyClass";
$newObject = new $className();
</code></pre>
<p>How do you do this sort of thing in Python? Or, am I totally not appreciating some fundamental difference with Python, and if so, what is it?</p>

<p>When I try to create a new RegionInfo with certain ISO 3166 country codes ("BD" for Bangladesh, "SO" for Somalia, "LK" for Sri Lanka), I get an ArgumentException that says it's not recognized.</p>
<p>What's the deal? The Intellisense of RegionInfo(string) says it conforms to ISO 3166, but these country/region codes are not supported? </p>
<p>I don't get it.</p>

<p>First of all (in case this is important) I'm using ActiveState's Perl (v5.8.7 built for MSWin32-x86-multi-thread).</p>
<p>I've just emerged from a three hour long debugging session, trying to find the source of an error. I found there was simply no error, but for some reason ADO's connection object was getting the <code>Errors.Count</code> increased with each printed message in my stored procedure's output.</p>
<p>Consider following Transact SQL code:</p>
<pre><code>CREATE PROCEDURE dbo.My_Sample() AS
BEGIN TRAN my_tran
-- Does something useful
if @@error <> 0 BEGIN
ROLLBACK TRAN my_tran
RAISERROR( 'SP My_Sample failed', 16, 1)
END ELSE BEGIN
COMMIT TRAN my_tran
PRINT 'SP My_Sample succeeded'
END
</code></pre>
<p>Now imagine a Perl sub more or less like:</p>
<pre><code>sub execute_SQL {
# $conn is an already opened ADO connection object
# pointing to my SQL Server
# $sql is the T-SQL statement to be executed
my($conn, $sql) = @_;
$conn->Execute($sql);
my $error_collection = $conn->Errors();
my $ecount = $error_collection->Count;
if ($ecount == 0 ) { return 0; }
print "\n" . $ecount . " errors found\n";
print "Executed SQL Code:\n$sql\n\n";
print "Errors while executing:\n";
foreach my $error (in $error_collection){
print "Error: [" . $error->{Number} . "] " . $error->{Description} . "\n";
}
return 1;
}
</code></pre>
<p>Somewhere else, in the main Perl code, I'm calling the above sub as:</p>
<pre><code>execute_SQL( $conn, 'EXEC dbo.My_Sample' );
</code></pre>
<p>In the end I got it that <em>every</em> PRINT statement causes a new pseudo-error to be appended to the ADO Errors collection. The quick fix I implemented was to change that PRINT in the SP into a SELECT, to bypass this.</p>
<p>The questions I'd like to ask are:</p>
<ul>
<li>Is this behaviour normal?</li>
<li>Is there a way to avoid/bypass it?</li>
</ul>

<p>I'm trying to get a query working that takes the values (sometimes just the first part of a string) from a form control. The problem I have is that it only returns records when the full string is typed in.</p>
<p>i.e. in the surname box, I should be able to type gr, and it brings up </p>
<p>green
grey
graham</p>
<p>but at present it's not bringing up anything uless the full search string is used.</p>
<p>There are 4 search controls on the form in question, and they are only used in the query if the box is filled in.</p>
<p>The query is :</p>
<pre><code>SELECT TabCustomers.*,
TabCustomers.CustomerForname AS NameSearch,
TabCustomers.CustomerSurname AS SurnameSearch,
TabCustomers.CustomerDOB AS DOBSearch,
TabCustomers.CustomerID AS MemberSearch
FROM TabCustomers
WHERE IIf([Forms]![FrmSearchCustomer]![SearchMember] Is Null

,[Forms]![FrmSearchCustomer]![SearchMember]=[customerid])=True
AND IIf([Forms]![FrmSearchCustomer].[SearchFore] Is Null
,True
,[Forms]![FrmSearchCustomer]![SearchFore] Like [customerforname] & "*")=True
AND IIf([Forms]![FrmSearchCustomer]![SearchLast] Is Null
,True
,[Forms]![FrmSearchCustomer]![SearchLast] Like [customersurname] & "*")=True
AND IIf([Forms]![FrmSearchCustomer]![Searchdate] Is Null
,True

<p>I have derived a TabControl with the express purpose of enabling double buffering, except nothing is working as expected. Here is the TabControl code:</p>
<pre><code>class DoubleBufferedTabControl : TabControl
{
public DoubleBufferedTabControl() : base()
{
this.DoubleBuffered = true;
this.SetStyle
(
ControlStyles.UserPaint |
ControlStyles.AllPaintingInWmPaint |
ControlStyles.ResizeRedraw |
ControlStyles.OptimizedDoubleBuffer |
ControlStyles.SupportsTransparentBackColor,
false
);
}
}
</code></pre>
<p>This Tabcontrol is then set with it's draw mode as 'OwnerDrawnFixed' so i can changed the colours. Here is the custom drawing method:</p>
<pre><code> private void Navigation_PageContent_DrawItem(object sender, DrawItemEventArgs e)
{
//Structure.
Graphics g = e.Graphics;
TabControl t = (TabControl)sender;
TabPage CurrentPage = t.TabPages[e.Index];
//Get the current tab
Rectangle CurrentTabRect = t.GetTabRect(e.Index);
//Get the last tab.
Rectangle LastTab = t.GetTabRect(t.TabPages.Count - 1);
//Main background rectangle.
Rectangle BackgroundRect = new Rectangle(LastTab.Width, t.Bounds.Y - 4, t.Width - (LastTab.Width), t.Height);
//Tab background rectangle.
Rectangle TabBackgroundRect = new Rectangle(0, LastTab.Y + LastTab.Height, LastTab.Width, t.Bounds.Height - (LastTab.Y + LastTab.Height));
//Set anitialiasing for the text.
e.Graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;
//String format for the text.
StringFormat StringFormat = new StringFormat();
StringFormat.Alignment = StringAlignment.Center;
StringFormat.LineAlignment = StringAlignment.Center;
//Fill the background.
g.FillRectangle(Brushes.LightGray, BackgroundRect);
g.FillRectangle(Brushes.Bisque, TabBackgroundRect);
//Draw the selected tab.
if(e.State == DrawItemState.Selected)
{
g.FillRectangle(Brushes.White, e.Bounds);
Rectangle SelectedTabOutline = new Rectangle(e.Bounds.X + 2, e.Bounds.Y + 2, e.Bounds.Width, e.Bounds.Height - 4);
g.DrawRectangle(new Pen(Brushes.LightGray, 4f), SelectedTabOutline);
g.DrawString(CurrentPage.Text, new Font("Arial", 12f, FontStyle.Bold, GraphicsUnit.Point), new SolidBrush(Color.FromArgb(70, 70, 70)), CurrentTabRect, StringFormat);
}
else
{
g.FillRectangle(new SolidBrush(Color.FromArgb(230, 230, 230)), e.Bounds);
g.DrawString(CurrentPage.Text, new Font("Arial", 12f, FontStyle.Regular, GraphicsUnit.Point), Brushes.Gray, CurrentTabRect, StringFormat);
}
}
</code></pre>
<p>All to no avail however, as this control is not double buffered and still flickers when resized.</p>
<p><strong>Any ideas?</strong></p>

<p>I'm trying to make a combo box that behaves somewhat like the Firefox 3 Awesomebar, with the following behavior:</p>
<ol>
<li>Type in text</li>
<li>Asynchronously bring back results</li>
<li>Up and down selects results in the list, <strong>BUT</strong> leaves the text that was typed in the entry box so the user can continue editing to limit the resultset differently</li>
<li>Enter fires an event that the parent form will handle</li>
</ol>
<p>I have the asynchronous results and filtering all working, but I don't have a good method for displaying and selecting within the results.</p>
<p>A combo box automatically fills the entry box with what is selected when you arrow down. Fails #3.</p>
<p>I've got the DevExpress controls, but their combo box does the same thing and I can't figure out how to override either.</p>
<p>A LookupEdit does not allow typing arbitrary stuff. Neither does a PopupContainerEdit.</p>
<p>I want behavior that's like a textbox with a listbox below it, and up/down events in the textbox get passed to the listbox. But if I try to make a custom control that combines the two like that, I have no clue how to "float" the listbox like the dropdown on a normal combo box.</p>
<p>Clues much appreciated!</p>

<p>The other day I set up an Ubuntu installation in a VM and went to gather the tools and libraries I figured I would need for programming mostly in C++.</p>
<p>I had a problem though, where to put things such as 3rd party source libraries, etc. From what I can gather, a lot of source distributions assume that a lot of their dependencies are already installed in a certain location and assume that a lot of tools are also installed in particular locations.</p>
<p>To give an example of what I currently do on Windows, is I have a directory where I keep all source code. <code>C:\code</code>. In this directory, I have a directory for all 3rd party libraries, <code>c:\code\thirdparty\libs</code>. This way I can easily set up relative paths for all of the dependencies of any projects I write or come across and wish to compile. The reason I am interested in setting up a linux programming environment is that it seems that both the tool and library dependency problems have been solved efficiently making it easy for example to build OpenSSH from source.</p>
<p>So what I was looking for was a decent convention I can use when I am trying to organize my projects and libraries on linux that is easy to maintain and easy to use.</p>

<p>My class is implementing a super-class method which which returns <code>List<JComponent></code>. The list being returned is read-only:</p>
<pre><code>public abstract class SuperClass {
public abstract List<JComponent> getComponents();
}
</code></pre>
<p>In my class, I want to return a field which is declared as List - i.e. a sub-list:</p>
<pre><code>public class SubClass extends SuperClass {
private List<JButton> buttons;
public List<JComponent> getComponents() {
return buttons;
}
}
</code></pre>
<p>This generates a compiler error, as <code>List<JButton></code> is not a subtype of <code>List<JComponent></code>.</p>
<p>I can understand why it doesn't compile, as it shouldn't be allowed to add a JTextField to a List of JButtons.</p>
<p>However, as the list is read-only, then "conceptually" this should be allowed. But, of course, the compiler doesn't know that it is read-only.</p>
<p>Is there any way to achieve what I want to achieve, without changing the method declaration in the super-class, and the field declaration in the sub-class?</p>
<p>Thanks,
Calum</p>

<p>I'm currently adding some new extended classes to this code:</p>
<pre><code>foreach (BaseType b in CollectionOfExtendedTypes) {
if (b is ExtendedType1) {
((ExtendedType1) b).foo = this;
}
else if (b is ExtendedType2) {
((ExtenedType2) b).foo = this;
}
else {
b.foo = this;
}
}
</code></pre>
<p>and was curious if there is a way to use the <code>is</code> keyword functionality in a switch statement?</p>

<p>Sometimes whenever I write a program in Linux and it crashes due to a bug of some sort, it will become an uninterruptible process and continue running forever until I restart my computer (even if I log out). My questions are:</p>
<ul>
<li>What causes a process to become uninterruptible?</li>
<li>How do I stop that from happening?</li>
<li>This is probably a dumb question, but is there any way to interrupt it without restarting my computer?</li>
</ul>

<p>I was wondering if there is any way to escape a CDATA end token (<code>]]></code>) within a CDATA section in an xml document. Or, more generally, if there is some escape sequence for using within a CDATA (but if it exists, I guess it'd probably only make sense to escape begin or end tokens, anyway). </p>
<p>Basically, can you have a begin or end token embedded in a CDATA and tell the parser not to interpret it but to treat it as just another character sequence.</p>
<p>Probably, you should just refactor your xml structure or your code if you find yourself trying to do that, but even though I've been working with xml on a daily basis for the last 3 years or so and I have never had this problem, I was wondering if it was possible. Just out of curiosity.</p>
<p>Edit:</p>
<p>Other than using html encoding...</p>

<p>Alright, I am going to state up front that this question may be too involved (amount of detail not complexity) for this medium. But I figured this was the best place to start.</p>
<p>I am attempting to setup a proof of concept project and my BIND configuration is my first big hurdle. I want to setup 3 DNS servers on 3 physical boxes. <strong>None</strong> of these boxes needs to resolve public addresses, this is internal <strong>only</strong>. I have read through how to setup internal roots in the (mostly) excellent DNS & BIND 5th ed book. But my translation of their example is not functional. All IP's are RFC 1918 non-routable.</p>
<p>Box 1 will be authoritative for addresses on the <em>box1.bogus</em> domain, and Box 2 will be authoritative for addresses on the <em>box2.bogus</em> domain. Box 3 will act as both an internal root and the TLD server for the domain <em>bogus</em>.</p>
<p>Current unresolved issues:</p>
<ul>
<li><p>I have a hints file on box 1 and 2 that contains a single <strong>NS</strong> record to the NS definition of the root zone. Additionally there is an <strong>A</strong> record that translates the NS to the ip of the root. if I <code>dig .</code> from box 1 I get an <em>authority</em> Section with the NS name, not an <em>answer</em> and <em>additional</em> record section. Therefore I am unable to actually resolve the IP of the root server from box 1.</p></li>
<li><p>If I point my <code>/etc/resolv.conf</code> from box 1 directly at the root server and do a <code>dig box1.bogus</code> I get the ns.box1.bogus <em>answer</em> record and the translation in the <em>additional</em> section. However on the next iteration (when should get the A record) I get <code>dig: couldn't get address for ns.box1.bogus</code></p></li>
</ul>
<p>Obviously my configs are <strong>not</strong> correct. I don't see a way to attach them to this post, so if people want to walk through this step by step I will cut'n'paste them into a comment for this question. Otherwise I am open to taking this 'offline' with a "DNS guy" to figure out where I'm missing a '.' or have one too many!</p>
<p>I personally think the web could do with another internal root example that doesn't make use of the Movie-U example.</p>
<p>OK, if we are going to do this, then we should use a concrete example eh? I have 3 machines setup on a private VLAN for testing this. As a sanity check I paired down all my relevant configs, condensed when able, and redeployed 2 of the namesevers. I left out Scratchy for now. Same results as above. Here are the configs and initial dig outputs.</p>

<p>I have a regexp I'm using with sed, but now I need to make it work in PHP also. I can't use system calls as they are disabled.</p>
<pre>
$ cat uglynumber.txt:
Ticket number : 303905694, FOO:BAR:BAR: Some text
Case ID:123,456,789:Foobar - Some other text
303867970;[FOOBAR] Some text goes here
Case Ref: 303658850 - Some random text here - host.tld #78854w
</pre>
<pre>
$ cat uglynumbers.txt | sed "s/[, ]//g;s/.*\([0-9]\{9\}\).*/\1/g"
303905694
123456789
303867970
303658850
</pre>
<p>So, how to do the same with PHP?</p>
<p>I found one example like this, but I can't inject that regexp into that.</p>
<pre>
if (preg_match("/.../", $line, $matches)) {
echo "Match was found";
echo $matches[0];

<p>I am trying to prevent data races in a multihreaded server. My problem is the following: there is a <code>List<RServer></code>, the type <code>RServer</code> is a class with several fields. Now, the server has several threads all running at the same time and they can modify both the <code>List</code> (adding more items) and the individual <code>RServer</code> instances (changing the fields).</p>
<p>So my strategy is to make a <code>readonly object RServerLock = new object( )</code> in each of the <code>RServer</code> instances and additionally a <code>readonly object RServerListLock = new object( )</code> and enclose all the code that modifies either (the <code>List</code> or a <code>RServer</code> instance) in a <code>lock</code>. Is this safe? What happens if a thread tries to lock a <code>RServerLock</code> <em>while</em> another one is locking it?</p>

<p>Well this is incredibly frustrating. After being nagged by Rails that I need to install the C-based MySQL adaptor, I did so... and then discovered that it won't work with MySQL under version 6. Now 'gem uninstall mysql' results in 'unknown gem mysql'. </p>
<p>I just spent half an hour trying to get the thing to install in the first place (by juggling all the "where the hell is my config file, anyway?" type of options).</p>
<p>Anyway, I can't find hints anywhere on how to use the ORIGINAL MySQL adaptor now that I've discovered that it's either that or an upgrade to MySQL 6, which I don't want to do since I'm using an XAMPP package that works very nicely already </p>
<p>(This is on my local box for testing, this is not a dev or production server issue. I'll deal with that later.)</p>
<p>So how do I either make sure Rails uses the built in version (using command line options?) OR remove the MySQL gem? </p>
<p>(Optional third option: Suck it up and upgrade my local copy of MySQL.)</p>
<p>edit: Turns out I was wrong about the version of MySQL I needed in the first place, and I fixed and upgraded a bunch of stuff. </p>
<p>However, my answer to the ORIGINAL question still stands: Delete the gem. If gem itself can't delete it, just delete all traces of it and RoR will default to the original adapter. This probably doesn't work in newer version of Rails, which (I think) REQUIRE the new adapter.</p>

<p>I have a class that I need to binary serialize. The class contains one field as below:</p>
<pre><code>private T[,] m_data;
</code></pre>
<p>These multi-dimensional arrays can be fairly large (hundreds of thousands of elements) and of any primitive type. When I tried standard .net serialization on an object the file written to disk was large and I think .net is storing a lot of repeated data about element types and possibly not as efficiently as could be done.</p>
<p>I have looked around for custom serializers but have not seen any that deal with multi-dimensional generic arrays. I have also experimented with built-in .net compression on a byte array of the memory stream following serializing with some success, but not as quick / compressed as I had hoped.</p>
<p>My question is, should I try and write a custom serializer to optimally serialize this array for the appropriate type (this seems a little daunting), or should I use standard .net serialization and add compression?</p>
<p>Any advice on the best approach would be most appreciated, or links to resources showing how to tackle serialization of a multi-dimensional generic array - as mentioned <a href="http://www.codeproject.com/KB/dotnet/FastSerializer.aspx" rel="noreferrer">existing examples</a> I have found do not support such structures.</p>

<p>I've just started working with ASP.NET MVC now that it's in beta. In my code, I'm running a simple LINQ to SQL query to get a list of results and passing that to my view. This sort of thing:</p>
<pre><code>var ords = from o in db.Orders
where o.OrderDate == DateTime.Today
select o;
return View(ords);
</code></pre>
<p>However, in my View, I realised that I'd need to access the customer's name for each order. I started using <code>o.Customer.Name</code> but I'm fairly certain that this is executing a separate query for each order (because of LINQ's lazy loading).</p>
<p>The logical way to cut down the number of queries would be to select the customer name at the same time. Something like:</p>
<pre><code>var ords = from o in db.Orders
from c in db.Customers
where o.OrderDate == DateTime.Today
and o.CustomerID == c.CustomerID
select new { o.OrderID, /* ... */, c.CustomerName };
return View(ords);
</code></pre>
<p>Except now my "ords" variable is an IEnumerable of an anonymous type.</p>
<p>Is it possible to declare an ASP.NET MVC View in such a way that it accepts an IEnumerable as its view data where T is defined by what gets passed from the controller, or will I have to define a concrete type to populate from my query?</p>

<p>I have a DataSet consisting of XML data, I can easily output this to a file:</p>
<pre><code>DataSet ds = new DataSet();
DataTable dt = new DataTable();
ds.Tables.Add(dt);
ds.Load(reader, LoadOption.PreserveChanges, ds.Tables[0]);
ds.WriteXml("C:\\test.xml");
</code></pre>
<p>However what I want to do is compress the XML into a ZIP or other type of compressed file and then just save this file to disk while splitting the ZIP file into 1MB chunks. I do not really want to save the uncompressed file, and then zip it, then split it.</p>
<p><strong>What I'm looking for specifically is:</strong></p>
<ol>
<li>a suitable compression library that I can stream the XML to and have the zip file(s) saved to disk</li>
<li>some sample C# code that can show me how to do this.</li>
</ol>

<p>I have a nice little file upload control I wrote for ASP.NET webforms that utilizes an IFrame and ASP.NET AJAX.</p>
<p>However, on large uploads, the browser times out before it can finish posting the form.</p>
<p>Is there a way I can increase this?</p>
<p>I'm not really interesting in alternative solutions, so don't suggest changing the entire thing out please. It works good for <5 meg uploads, I'd just like to get it up to about 8mb.</p>
<p>EDIT: Setting the timeout in Page_Load didn't appear to change anything.</p>

<p>I have an API consisting of ASP.NET webservices callable through GET/POST/SOAP.</p>
<p>A new functionality will require me to accept files through this webservice. Basically I'm allowing users to upload files to a file archive through the API, which they'd otherwise do by logging into our browser based administration system.</p>
<p>The API needs to be as easily consumed as possible. I'm thinking of dropping SOAP support since our PHP clients mainly use the GET/POST methods, and the .NET clients don't mind either way. With that as a prerequisite, I'm thinking of simply creating an UploadFile(fileName) method, and the requiring the user to send the file through POST as a normal file upload.</p>
<p>However, I will not be able to specify the file field as a parameter to the method, right? So if I simply state in the documentation "file should be sent in POST field called 'File'", would that pose any problems when I need to read the file?</p>
<p>All files are in binary format, PDF's, various image formats, FLV and so forth. Also, file sizes will mainly be in the 2-20MB vicinity, but given the above solution, would I have any troubles accepting files in the 250MB area?</p>
<p>Receiving a file this way would result in the file being loaded completely into memory, before I write it to disk - is there any way around this, besides letting the service receive a Stream and thus disabling me from accepting other parameters, and hindering the easy usage of the service?</p>
<hr>
<p>Besides what's possible on my side, I'm also curious in regards to how I make it as easy as possible for the callees to send the file. I'm guessing POST is one of the most accessible ways of receiving the file, but if anyone has any comments, I'd like to hear them as well.</p>

<p>So, no matter what I seem to do, I cannot seem to avoid having Dev C++ spew out numerous Multiple Definition errors as a result of me including the same header file in multiple source code files in the same project. I'd strongly prefer to avoid having to dump all my source code into one file and only include the header once, as that's going to make my file very long and difficult to manage.</p>
<p>Essentially, this is what's going on:</p>
<pre><code>#ifndef _myheader_h
#define _myheader_h
typedef struct MYSTRUCT{
int blah;
int blah2; } MYSTRUCT;
MYSTRUCT Job_Grunt;
MYSTRUCT *Grunt = &Job_Grunt;
MYSTRUCT Job_Uruk;
MYSTRUCT *Uruk = &Job_Grunt;
int Other_data[100];
void load_jobs();
#endif
</code></pre>
<p>Example Cpp File (They pretty much all look something like this):</p>
<pre><code>#include "myheader.h"
void load_jobs(){
Grunt->blah = 1;
Grunt->blah2 = 14;
Uruk->blah = 2;
Uruk->blah2 = 15;
return; }
</code></pre>
<p>Bear in mind that I have about 5 cpp files that include this one header, each one dealing with a different type of struct found in the header file. In this example there was only the one struct containing a couple of members, when there are about 4-6 different structs with many more members in the actual header file. All the files I've included it in follow the same formula as you see in this example here.</p>
<p>Now I understand that the header guard only stops each individual cpp file from including the header file more than once. What would seem to be happening is that when the compiler reads the include at the start of each cpp, it defines the header file all over again, which is causing it to spit out lines and lines of:</p>
<pre><code>Multiple Definition of Uruk, first defined here
Multiple Definition of Job_Uruk, first defined here
Multiple Definition of Grunt, first defined here
Multiple Definition of Job_Grunt, first defined here
Multiple Definition of Other_data, first defined here
</code></pre>
<p>I'll see a set of this for just about every cpp file in the project which includes the header. I've tried moving the definitions of the struct and the struct variables to the cpp files, but then the other cpp files cannot see them or work with them, which is very important as I need all files in the project to be able to work with these structs.</p>
<p>But the single most confusing part about this problem requires a little more explanation:</p>
<p>The way I'm setting up these multiple files in this project is identical to the book I'm working with, All In One Game Programming by John S. Harbour. I ran into the exact same problems when I created the files for example projects in the book which called for one header included by multiple cpps in the same project.</p>
<p>I could type them out, word for word from the book, and I do mean word for word...<br>
and I'd get the series of MD errors for every cpp in the project. </p>
<p>If I loaded the example project from the CD included with the book, it would compile and run without a problem, allthough the files themselves, as well as the project options, were by all appearances identical to the ones I had created.</p>
<p>If I created my own project file, and simply added the source and header files for the example project from the CD, this, too, would also compile and run, though I can find no difference between those and mine.</p>
<p>So then, I tried making my own project file, then creating the blank source and header files and adding them to it, and then filling them by copying and pasting their contents from the files on the CD they were meant to correspond to(the same ones that had worked).
And sure enough, I'd get the same thing...lines and lines of MD error messages.</p>
<p>I'm absolutely baffled. I've repeated all these methods multiple times, and am certain I'm not mistyping or miscopying the code. There just seems to be something about the premade files themselves; some configuration setting or something else I'm missing entirely...that will cause them to compile correctly while the files I make myself won't.</p>

<p>In a previous question, I asked about various ORM libraries. It turns out Kohana looks very clean yet functional for the purposes of ORM. I already have an MVC framework that I am working in though. If I don't want to run it as a framework, what is the right fileset to include to just give me the DB and ORM base class files?</p>
<p>Update:</p>
<p>I jumped in and started looking at the ORM source code.. One thing was immediately confusing to me.. all the ORM classes have the class name appended with _CORE i.e. ORM_Core ORM_Iterator_Core, but the code everywhere is extending the ORM class. Problem is, I've searched the whole code base 6 different ways, and I've never seen a plain ORM class def nor an ORM interface def or anything.. Could someone enlighten me on where that magic happens?</p>

<p>Is there a way to merge two primary keys into one and then cascade update all affected relationships? Here's the scenario:</p>
<p>Customers (idCustomer int PK, Company varchar(50), etc)</p>
<p>CustomerContacts (idCustomerContact int PK, idCustomer int FK, Name varchar(50), etc)</p>
<p>CustomerNotes (idCustomerNote int PK, idCustomer int FK, Note Text, etc)</p>
<p>Sometimes customers need to be merged into one. For example, you have a customer with the id of 1 and another with the id of 2. You want to merge both, so that everything that was 2 is now 1. I know I could write a script that updates all affected tables one by one, but I'd like to make it more future proof by using the cascade rules, so I don't have to update the script every time there is a new relationship added.</p>
<p>Any ideas?</p>

<p><a href="http://www.php.net/features.safe-mode" rel="noreferrer">open_basedir</a> limits the files that can be opened by PHP within a directory-tree.</p>
<p>I am storing several class libraries and configuration files outside of my web root directory. This way the web server does not make them publicly accessible. However when I try to include them from my application I get an open_basedir restriction error like this:</p>
<blockquote>
<p>Warning: realpath()
[function.realpath]: open_basedir
restriction in effect.
File(/var/www/vhosts/domain.tld/zend/application)
is not within the allowed path(s):
(/var/www/vhosts/domain.tld/httpdocs:/tmp)
in
/var/www/vhosts/domain.tld/httpdocs/index.php
on line 5</p>
</blockquote>
<p>My web root is here:</p>
<pre><code>/var/www/vhosts/domain.tld/httpdocs
</code></pre>
<p>My libraries and configuration directory are here:</p>
<pre><code>/var/www/vhosts/domain.tld/zend
</code></pre>
<p>What would be the best workaround to relax the open_basedir restriction so that the the directory tree under the domain folder becomes available to my application? I have a number of domains that I want to do this with, and I'm also obviously wary of creating security vulnerabilities.</p>
<p>Note: I am using CentOS, Apache, Plesk, and I have root ssh access to the server. And though this doesn't apply to Zend Framework directly, I am using it in this instance. So here is the inclusion from Zend's bootstrap:</p>
<pre><code>define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../zend/application/'));
set_include_path(APPLICATION_PATH . '/../zend/library' . PATH_SEPARATOR . get_include_path());
</code></pre>

<p>I am new to MySQL and PHP(as you can probably tell) and I was wondering if anybody knew an easy way to import a CSV file into a MySQL table.</p>
<blockquote>
<p>"There are any number of ways to input
csv into mysql depending in what kind
of access you have, if you can use the
mysql client directly there is a
command to load delimited data,
something like that could basically be
entered directly in cron and keep
itself up to date. Otherwise there are
various php scripts to do that sort of
thing."</p>
</blockquote>
<p>That is something a friend told me to do, is that the easiest/best way to do it? If it is would someone mind explaining it to me?</p>
<p>Thank you </p>

<p>Suppose you have two models, User and City, joined by a third model CityPermission:</p>
<pre><code>class CityPermission < ActiveRecord::Base
belongs_to :city
belongs_to :user
end
class City < ActiveRecord::Base
has_many :city_permissions
has_many :users, :through => :city_permissions
end
class User < ActiveRecord::Base
has_many :city_permissions
has_many :cities, :through => :city_permissions
end
</code></pre>
<p>Currently, I create the join table, and the index for the table, using the following migration code snippet:</p>
<pre><code>create_table :city_permissions do |t|
t.integer :user_id, :city_id
t.other_fields ...
end
add_index(:city_permissions, :user_id)
add_index(:city_permissions, :city_id)
</code></pre>
<p>Are these the optimal indexes to create? Will these indexes allow quick access back and forth through the join table, as well as quick lookups within the table itself, or is there some other better way? To restate this a bit differently, will these indexes, given <code>city</code> and <code>user</code> are instance variables of class City and User, allow <code>city.users</code>, <code>city.city_permissions</code>, <code>user.cities</code>, and <code>user.city_permissions</code> to all perform equally well?</p>

<p>What is the most efficient way in C# 2.0 to check each character in a string and return true if they are all valid hexadecimal characters and false otherwise?</p>
<h3>Example</h3>
<pre><code>void Test()
{
OnlyHexInString("123ABC"); // Returns true
OnlyHexInString("123def"); // Returns true
OnlyHexInString("123g"); // Returns false
}
bool OnlyHexInString(string text)
{
// Most efficient algorithm to check each digit in C# 2.0 goes here
}
</code></pre>

<p>It works outside of the @media block in Firefox:</p>

<p>I can't find a definitive answer. Since C# 2.0 you've been able to declare</p>
<pre><code>int? i = 125;
</code></pre>
<p>as shorthand for</p>
<pre><code>Nullable<int> i = Nullable<int>(123);
</code></pre>
<p>I recall reading somewhere that VB.NET did not allow this shortcut. But low and behold, I tried it in VS 2008 today and it works.</p>
<p>Does anyone know whether it's been this way since .NET 2.0 or was this added later?</p>

<p>I need to parse a transcript of a live chat conversation. My first thought on seeing the file was to throw regular expressions at the problem but I was wondering what other approaches people have used. </p>
<p>I put elegant in the title as i've previously found that this type of task has a danger of getting hard to maintain just relying on regular expressions.</p>
<p>The transcripts are being generated by www.providesupport.com and emailed to an account, I then extract a plain text transcript attachment from the email.</p>
<p>The reason for parsing the file is to extract the conversation text for later but also to identify visitors and operators names so that the information can be made available via a CRM.</p>
<p>Here is an example of a transcript file:</p>
<pre><code>Chat Transcript
Visitor: Random Website Visitor
Operator: Milton
Company: Initech
Started: 16 Oct 2008 9:13:58
Finished: 16 Oct 2008 9:45:44
Random Website Visitor: Where do i get the cover sheet for the TPS report?
* There are no operators available at the moment. If you would like to leave a message, please type it in the input field below and click "Send" button
* Call accepted by operator Milton. Currently in room: Milton, Random Website Visitor.
Milton: Y-- Excuse me. You-- I believe you have my stapler?
Random Website Visitor: I really just need the cover sheet, okay?
Milton: it's not okay because if they take my stapler then I'll, I'll, I'll set the building on fire...
Random Website Visitor: oh i found it, thanks anyway.
* Random Website Visitor is now off-line and may not reply. Currently in room: Milton.
Milton: Well, Ok. But… that's the last straw.
* Milton has left the conversation. Currently in room: room is empty.

<p>I am starting to develop an Eclipse plugin (technically, an OSGi plugin) and one of the first problems I've run into is that I can't seem to control the commons-logging output as I normally would.</p>
<p>I've included the commons-logging package in the plugin dependencies, and indeed, when I log something (at INFO or higher severity) it is logged to the console. However, I can't seem to log at any lower level (such as DEBUG or TRACE).</p>
<p>I have specified a log4j.properties file, and it is on the classpath (for the runtime, just as the commons-logging package is) but none of the settings in that properties file have any impact on the behavior of the logger.</p>
<p>Here's the log4j.properties file:</p>
<pre><code># Log4j Logging levels, in order of decreasing importance are:
# FATAL, ERROR, WARN, INFO, DEBUG, TRACE
#
# Root logger option
log4j.rootLogger=ERROR,stdout
#,LOGFILE
# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %r (%l) %t%n - %m%n
</code></pre>
<p>What do I need to do so that I can actually control the output of the logger?</p>
<p>Here are some sample output messages, in the hopes that the formatting may coincide with a default for java.util.logging, or provide other hints to someone:</p>
<pre><code>Oct 21, 2008 11:01:23 PM com.stottlerhenke.sentinel.client.Activator start
SEVERE: fatal_message
Oct 21, 2008 11:01:23 PM com.stottlerhenke.sentinel.client.Activator start
WARNING: warn_message
Oct 21, 2008 11:01:23 PM com.stottlerhenke.sentinel.client.Activator start
INFO: info_message
</code></pre>
<p><strong>Update:</strong></p>
<p>I have now tried various combinations of:</p>
<ul>
<li>org.osgi.service.log.LogService et al.</li>
<li><a href="http://www.slf4j.org/" rel="noreferrer">slf4j</a></li>
<li><a href="http://logging.apache.org/log4j/" rel="noreferrer">Log4J</a></li>
<li><a href="http://commons.apache.org/logging/" rel="noreferrer">Commons-logging</a></li>
<li><a href="http://java.sun.com/j2se/1.4.2/docs/api/java/util/logging/package-summary.html" rel="noreferrer">java.util.logging</a></li>
</ul>
<p>and I can <em>only</em> get DEBUG, or lower, level messages to appear if I am running OSGi manually from a prompt (which is impractical for what I am developing). Furthermore, I can't effect any other type of logging configuration via various properties files. Everything I try in that regard seems to be overridden by an eclipse setting.</p>
<p>I've also tried putting various config files for the above libraries in numerous places, including as plug-in fragments attached to their respective libraries as suggested <a href="http://www.eclipsezone.com/eclipse/forums/t99588.html" rel="noreferrer">here</a>, and still, the same result happens.</p>
<p>I've implemented a custom LogListener, and traced the entire path of a log message (as well as I know how, anyway) with System.out.println's, and debug messages <em>are</em> present right up until they are output by whatever underlying logging API I'm using, then they disappear.</p>

<p>In my question <a href="https://stackoverflow.com/questions/184729/as-a-mockist-tdd-practitioner-should-i-mock-other-methods-in-the-same-class-as">As a “mockist” TDD practitioner, should I mock other methods in the same class as the method under test?</a>, <a href="https://stackoverflow.com/users/20487/avdi">Avdi</a> answered "Personally I think that mocking on self is almost always a code smell. It's testing the implementation rather than the behavior." He may be right, but often I can't distinguish between the implementation and the behavior.</p>
<p>I have another example (in Python-style pseudo-code) that may lead to helpful answers:</p>
<pre><code>class Consumer:
def spec_dirpath:
client = VCS.get_connection(self.vcs_client_name)
client.sync()
return client.dirpath()
def spec_filepath:
filepath = os.path.join(spec_dirpath(), self.spec_filename)
if not os.path.exists(filepath):
raise ConsumerException
return filepath
def get_components:
return Components.get_components_from_spec_file(self.spec_filepath())
</code></pre>
<p>The idea here is that the get_components method calls the spec_filepath method in order to get a path to a file that the get_components_from_spec_file Components class method will read a list of components from. The spec_filepath method in turn calls spec_dirpath, which syncs the directory containing the spec file from the VCS system and returns the path to that directory. (Try not to look for bugs in this code--it's pseudo-code, after all.)</p>
<p>I'm looking for advice on how to test these methods...</p>
<p>Testing spec_dirpath should be quite straightforward. I can mock the VCS class and have it return a mock object and confirm the appropriate methods are called (and that the spec_dirpath method returns what the mock's dirpath method returns).</p>
<p>But if I don't mock spec_dirpath while testing spec_filepath, how do I avoid duplicating the same test code from the spec_dirpath code in the spec_filepath test? And if I don't mock spec_filepath while testing get_components, how do I avoid duplicating the test code from both spec_filepath <em>and</em> spec_dirpath?</p>

<p>Take the following generics example</p>
<pre><code>import java.util.List;
import java.util.ArrayList;
public class GenericsTest {
private List<Animal> myList;
public static void main(String args[]) {
new GenericsTest(new ArrayList<Animal>()).add(new Dog());
}
public GenericsTest(List<Animal> list) {
myList = list;
}
public void add(Animal a) {
myList.add(a);
}
public interface Animal {}
public static class Dog implements Animal {}
public static class Cat implements Animal {}
}
</code></pre>
<p>It works fine. But as you know, you cannot construct it with</p>
<pre><code>new GenericsTest(new ArrayList<Dog>());
</code></pre>
<p>because, as you know, the add(Animal) would make possible to add <code>Cat</code>s. The <em>suggested</em> way of solving this problem, i.e. wildcarding does not work either, because, yes, you can change every <code>List<Animal></code> in <code>List<? extends Animal></code> but it has the same problem: you can create the <code>GenericsTest</code> with <code>List<Cat></code> and then add <code>Dog</code>s.</p>
<p>So my question is: is there a convenient way to write this class once, and then use it for all the possible <code>Animals</code>? Of course it should solve straightforwardly the above mentioned problem. </p>

<p>We all know you can't do the following because of <code>ConcurrentModificationException</code>:</p>
<pre><code>for (Object i : l) {
if (condition(i)) {
l.remove(i);
}
}
</code></pre>
<p>But this apparently works sometimes, but not always. Here's some specific code:</p>
<pre class="lang-java prettyprint-override"><code>public static void main(String[] args) {
Collection<Integer> l = new ArrayList<>();
for (int i = 0; i < 10; ++i) {
l.add(4);
l.add(5);
l.add(6);
}
for (int i : l) {
if (i == 5) {
l.remove(i);
}
}
System.out.println(l);
}
</code></pre>
<p>This, of course, results in:</p>
<pre><code>Exception in thread "main" java.util.ConcurrentModificationException
</code></pre>
<p>Even though multiple threads aren't doing it. Anyway.</p>
<p>What's the best solution to this problem? How can I remove an item from the collection in a loop without throwing this exception?</p>
<p>I'm also using an arbitrary <code>Collection</code> here, not necessarily an <code>ArrayList</code>, so you can't rely on <code>get</code>.</p>

<p>I've figured out how to set VC++ to compile code into a .lib file instead of a .exe, but I'm having trouble getting a lib to link together with my other .obj files.</p>
<p>Here is how I have the library and application folders set up. (I'm not sure if this is right)</p>
<pre><code>AppFolder
App.sln
App.ncb
*.h
*.cpp
Debug
*.obj
App.exe
</code></pre>
<p>and somewhere else on the hard drive...</p>
<pre><code>LibraryFolder
lib
Library.lib
include
LibrarySolutionFolder
Library.sln
Library.ncb
*.h
*.cpp
Debug
*.obj
Library.lib
</code></pre>
<p>I've been #including the library *.h files from my app's cpp files, and everything compiles fine. It's just when it links I get a list of all the .lib
files that are being searched, and Library.lib isn't on there even though I have it listed in VC++ directories.
How can I get this to link? (And am I structuring the library folders correctly?)</p>

<p>I have two LINQ objects which have exactly the same columns and I would like to be able to update one with the fields from the other. I first create a new object from some data in a file, then I query the database for an existing item with the same ID. What I would like to be able to do is update the existing objects details with the newly created objects details. </p>
<p>So far the way I have been doing it is to list all the columns and update them manually but as you can see this can cause maintenance headaches.</p>
<pre><code> With OldCaller
.ADDRESS = NewCaller.ADDRESS
.COMPANY = NewCaller.COMPANY
.CONTACT_HOURS = NewCaller.CONTACT_HOURS
.CONTACT_NAME = NewCaller.CONTACT_NAME
.CUSTOMER_ID = NewCaller.CUSTOMER_ID
.EMAIL_ADDRESS = NewCaller.EMAIL_ADDRESS
.FAX_NUMBER = NewCaller.FAX_NUMBER
.FAX_TYPE = NewCaller.FAX_TYPE
.MOBILE = NewCaller.MOBILE
.POSTCODE = NewCaller.POSTCODE
.PUBLIC_ADDRESS = NewCaller.PUBLIC_ADDRESS
.PUBLIC_TELEPHONE = NewCaller.PUBLIC_TELEPHONE
.STATE = NewCaller.STATE
.SUBURB = NewCaller.SUBURB
.TELEPHONE = NewCaller.TELEPHONE
End With
</code></pre>
<p>I would like to be able to find a way to clean this up a bit. Does anyone know of a better way to do what I need.</p>

<p>Note: I am just consuming webservice I have no control over webservice code.</p>
<p>So in .net 2.0 I reference the webservice and see a class in the webservice namespace, say foobar. It's defined as:</p>
<pre><code>public class foobar : System.Web.Services.Protocols.SoapHttpClientProtocol
</code></pre>
<p>but in .net 3.5 when i add a reference to the same webservice I no longer have this foobar class available. I do see foobarSoap which is an interface which exposes all of the methods in the foobar class above. It's defined as:</p>
<pre><code>public interface foobarSoap
</code></pre>
<p>However it doesn't expose the properties (for obvious reasons).</p>
<p>I need to access these properties. How do I do it?</p>

<p>I have an application which allows for multiple NSDocuments to be open. In this application is a single utility window that contains some functionality that I want to apply to the frontmost document.</p>
<p>I am trying to use bindings here, so the trick is how to cleanly bind the user interface of the utility window to the frontmost document. The goal is that then switching the frontmost document window will update the view in the utility window; controls that are bound to properties of the frontmost document's model would be updated appropriately when state changes in the document's model, etc.</p>
<p>For sending actions from such a window, it's easy to just use first responder; the document object can intercept actions via the responder chain. But I want more than this, and of course you can't bind to the first responder.</p>
<p>A few ideas that I have:</p>
<ul>
<li>put an object controller in my nib for the shared window. When a document window changes frontmost status, change the content of that binding. A disadvantage of this is that if I were to have another kind of utility window, I'd have to remember to hook up the bindings from the document window to that utility window too!</li>
<li>Make an accessor in the application delegate that gets the frontmost document window by traversing the window list. My utility window would just bind through the application delegate's method. A disadvantage here is that it's not KVO compliant</li>
<li>Have a getter and setter in the application delegate to determine (and perhaps set to be KVO-compliant? would that make sense?) the frontmost document. Perhaps use window notifications set an ivar to the appropriate value when a window loses main status. <b>Update: I'm using this for now, and it actually seems pretty clean. I set the value from the <em>windowDidBecomeMain</em> notification of my doc window and clear it (if it's the current value) in <em>windowWillClose</em>. Unless there is any major objection, this is probably the approach I'll use.</b></li>
<li><a href="http://forums.macrumors.com/showthread.php?t=215361" rel="nofollow noreferrer">One idea</a> was to bind to mainWindow.windowController.document ... this comes close, except that when my shared window becomes main, then this binding goes away. So really I need to find the frontmost <em>document</em> window's controller (and of the right class).</li>
</ul>
<p>None of these seem quite right. Is there a better way to do this that I'm missing?</p>

<p>Is there an easy way to convert between color models in Java (RGB, HSV and Lab). </p>
<p>Assuming RGB color model:</p>
<ul>
<li>How do I calculate black body spectrum color palette? I want to use it for a heatmap chart.</li>
<li>How about single-wavelength spectrum?</li>
</ul>
<p><strong>Edit:</strong> I found that the <a href="http://java.sun.com/javase/6/docs/api/java/awt/color/ColorSpace.html" rel="nofollow noreferrer">ColorSpace</a> class can be used for conversions between RGB/CIE and many other color models.</p>

<p>I need to perform a filtered query from within a django template, to get a set of objects equivalent to python code within a view:</p>
<pre><code>queryset = Modelclass.objects.filter(somekey=foo)
</code></pre>
<p>In my template I would like to do</p>
<pre><code>{% for object in data.somekey_set.FILTER %}
</code></pre>
<p>but I just can't seem to find out how to write FILTER.</p>

<p>Because of several iframes, XUL browser elements, and so forth, I have a number of window objects in my XULRunner application. I'm looking for the best way to find the window object that a specified node belongs to using JavaScript.</p>
<p>So, to be more specific, given node x, I need to find the specific window object that contains x.</p>

<p>I'm in the process of trying to move our company from SalesForce to SugarCRM, but I've run in to a nasty bug (the moment I add a custom field to Accounts, all accounts stop showing up). We've paid for support from the SugarCRM people, but they only have take-forever-then-get-a-worthless-response-level tech support for the open-source version (and we avoid proprietary software like the plague). Oh, and did I mention our Salesforce contract expires at the end of the week?</p>
<p>So, long story short, I'm stuck debugging the SugarCRM app myself. I'm an decently experienced programmer, and I have baseline PHP competency, but I don't even know where to being trying to solve this issue. Can any Sugar developers out there recommend any kind of process for debugging Sugar? Are there any resources out there that would help me to understand what the different PHP files do, or how the Sugar system works overall? </p>
<p>Just as an example of the sort of thing I'm talking about: I figured out how to get sugar to print stack traces, and by following several I noticed a pattern with all the problem lines involving <pre>$this->_tpl_vars</pre>
I'd love to try and figure out why that method call isn't working, but I don't know:</p>
<p>A) what <code>_tpl_vars</code> is supposed to do<br/>
B) where <code>_tpl_vars</code> is defined<br/>
C) what <code>$this</code> is supposed to be<br/>
D) where in the framework <code>$this</code> gets set<br/>
etc.</p>
<p>So if anyone can help explain how/where I would start finding answers to these questions, I'd be incredibly grateful.</p>

<p>Session variables are normally keept in the web server RAM memory.</p>
<p>In a cluster, each request made by a client can be handled by a different cluster node. right?!</p>
<p>So, in this case... </p>
<ul>
<li>What happens with session variables? Aren't they stored in the nodes RAM memory? </li>
<li>How the other nodes will handled my request correctly if it doesn't have my session variables, or at least all of it?</li>
<li>This issue is treated by the web server (Apache, IIS) or by the language runtime (PHP, ASP.NET, Ruby, JSP)?</li>
</ul>
<p>EDIT: Is there some solution for <strong>Classic ASP</strong>?</p>

<p>I've started to use constructs like these:</p>
<pre><code>class DictObj(object):
def __init__(self):
self.d = {}
def __getattr__(self, m):
return self.d.get(m, None)
def __setattr__(self, m, v):
super.__setattr__(self, m, v)
</code></pre>
<p>Update: based on this thread, I've revised the DictObj implementation to:</p>
<pre><code>class dotdict(dict):
def __getattr__(self, attr):
return self.get(attr, None)
__setattr__= dict.__setitem__
__delattr__= dict.__delitem__
class AutoEnum(object):
def __init__(self):
self.counter = 0
self.d = {}
def __getattr__(self, c):
if c not in self.d:
self.d[c] = self.counter
self.counter += 1
return self.d[c]
</code></pre>
<p>where DictObj is a dictionary that can be accessed via dot notation:</p>
<pre><code>d = DictObj()
d.something = 'one'
</code></pre>
<p>I find it more aesthetically pleasing than <code>d['something']</code>. Note that accessing an undefined key returns None instead of raising an exception, which is also nice.</p>
<p>Update: Smashery makes a good point, which mhawke expands on for an easier solution. I'm wondering if there are any undesirable side effects of using <strong>dict</strong> instead of defining a new dictionary; if not, I like mhawke's solution a lot.</p>
<p>AutoEnum is an auto-incrementing Enum, used like this:</p>
<pre><code>CMD = AutoEnum()
cmds = {
"peek": CMD.PEEK,
"look": CMD.PEEK,
"help": CMD.HELP,
"poke": CMD.POKE,
"modify": CMD.POKE,
}
</code></pre>
<p>Both are working well for me, but I'm feeling unpythonic about them. </p>
<p>Are these in fact bad constructs?</p>
