<p>I'm trying to create a UDF in <code>SQL Server 2005 Express</code> as below:</p>
<pre><code>CREATE FUNCTION [CombineValues] ()
RETURNS VARCHAR(8000)
AS
BEGIN
DECLARE @CuisineList VARCHAR(8000);
RETURN
(
SELECT @CuisineList = COALESCE(@CuisineList + ', ', '') +
CAST(Cuisine AS varchar(20))
FROM Cuisines
)
END
</code></pre>
<p>Cuisines has the structure:</p>
<pre><code>CuisineID INT PK,
Cuisine VARCHAR(20)
</code></pre>
<p>When I try to create the function as above, I get an error: </p>
<blockquote>
<p>Msg 102, Level 15, State 1, Procedure CombineValues, Line 10 Incorrect
syntax near '='.</p>
</blockquote>
<p>What am I doing wrong?</p>

<p>When adding new properties to classes, I find myself typing the same things over and over in xcode:</p>
<ol>
<li><code>add TYPE *NAME;</code> (in .h interface)</li>
<li><code>add @property (nonatomic, retain) TYPE *NAME;</code> (in .h)</li>
<li><code>add @synthesize NAME;</code> (in .m)</li>
<li><code>add [NAME release];</code> (in .m dealloc)</li>
</ol>
<p>(I'm in a non-garbage collected environment.)</p>
<p>How can I do this automatically?</p>

<p>Is there any way to create the <em>query parameters</em> for doing a <em>GET request</em> in JavaScript?</p>
<p>Just like in Python you have <a href="http://web.archive.org/web/20080926234926/http://docs.python.org:80/lib/module-urllib.html" rel="noreferrer"><code>urllib.urlencode()</code></a>, which takes in a dictionary (or list of two tuples) and creates a string like <code>'var1=value1&var2=value2'</code>.</p>

<p>I'm trying to setup a new computer to synchronize with my SVN repository that's hosted with cvsdude.com.</p>
<p>I get this error:</p>
<p>![SVN Error][1] - <em>removed image shack image that had been replaced by an advert</em></p>
<p>Here's what I did (these have worked in the past):</p>
<ol>
<li><p>Downloaded and installed TortoiseSVN</p></li>
<li><p>Created a new folder C:\aspwebsite</p></li>
<li><p>Right-clicked, chose SVN Checkout...</p></li>
<li><p>Entered the following information, clicked OK:</p>
<ul>
<li>URL of repository: <a href="https://<reponame>-svn.cvsdude.com/aspwebsite" rel="nofollow noreferrer">https://<reponame>-svn.cvsdude.com/aspwebsite</a></li>
<li>Checkout directory: C:\aspwebsite</li>
<li>Checkout depth: Fully recursive</li>
<li>Omit externals: Unchecked</li>
<li>Revision: HEAD revision</li>
</ul></li>
<li><p>Got TortoiseSVN error:</p>
<ul>
<li>OPTIONS of '<a href="https://<reponame>-svn.cvsdude.com/aspwebsite" rel="nofollow noreferrer">https://<reponame>-svn.cvsdude.com/aspwebsite</a>': could not connect to server (<a href="https://<reponame>-svn.cvsdude.com" rel="nofollow noreferrer">https://<reponame>-svn.cvsdude.com</a>)</li>
</ul></li>
</ol>
<p>Rather than getting the error, TortoiseSVN should have asked for my username and password and then downloaded about 90MB.</p>
<p>Why can't I checkout from my Subversion repository?</p>

<p>I imported a series of blogger posts (via xml) into WordPress, and the YouTube embed tags were removed.
YouTube URLs in posts are not identified. Instead, just the text of the url is left. Possibly as opposed to full embed tags.
I'm trying to restore the embed codes so it's seen.</p>
<p>Another fact that is notable in the XML import is that [EMBLED CONTENT] appears instead of the url, that is, the video...</p>

<p>Basically I’ve heard that certain conditions will cause .NET to blow past the <code>finally</code> block. Does anyone know what those conditions are?</p>

<p>No doubt, it's essential for understanding code to give member variables a prefix so that they can easily be distinguished from "normal" variables.</p>
<p>But what kind of prefix do you use?</p>
<p>I have been working on projects where we used <strong>m_</strong> as prefix, on other projects we used an underscore only (which I personally don't like, because an underscore only is not demonstrative enough).</p>
<p>On another project we used a long prefix form, that also included the variable type. <strong>mul_</strong> for example is the prefix of a <strong>m</strong>ember variable of type <strong>u</strong>nsigned <strong>l</strong>ong.</p>
<p>Now let me know what kind of prefix you use (and please give a reason for it).</p>
<p><strong>EDIT:</strong> Most of you seem to code without special prefixes for member variables! Does this depend on the language? From my experience, <strong>C++ code</strong> tends to use an underscore or <strong>m_</strong> as a prefix for member variables. What about other languages?</p>

<p>I am interested to know what strategies people have to keep their code AND work versioned across multiple machines. For example I have a desktop PC running XP, a macbook running OSX and VMWare running XP as well as a sales laptop for running product demos. I want to know how I can always have these in sync. Subversion is a possibility for this but i find it less useful for dealing with binary files - maybe I have overlooked something here. What do other people use as they must have similar issues? Do they keep all files on a USB drive and never on the local file system. I am not always online so remote storage is not really an option.</p>

<p>Some of the controls I've created seem to default to the old Windows 95 theme, how do I prevent this? Here's an example of a button that does not retain the Operating System's native appearance (I'm using Vista as my development environment):</p>
<pre><code>HWND button = CreateWindowEx(NULL, L"BUTTON", L"OK", WS_VISIBLE | WS_CHILD | BS_PUSHBUTTON,
170, 340, 80, 25, hwnd, NULL, GetModuleHandle(NULL), NULL);
</code></pre>
<p>I'm using native C++ with the Windows API, no managed code.</p>

<p>I am working with a Visual Studio 2005 C++ solution that includes multiple projects (about 30).
Based upon my experience, it often becomes annoying to maintain all the properties of the projects (i.e include path, lib path, linked libs, code generation options, ...), as you often have to click each and every project in order to modify them.
The situation becomes even worse when you have multiple configurations (Debug, Release, Release 64 bits, ...).</p>
<p>Real life examples:</p>
<ul>
<li>Assume you want to use a new library, and you need to add the include path to this library to all projects.
How will you avoid to have to edit the properties of each an every project?</li>
<li>Assume you want to test drive a new version of library (say version 2.1beta) so that you need to quickly change the include paths / library path / linked library for a set of projects?</li>
</ul>
<p>Notes:</p>
<ul>
<li>I am aware that it is possible to select multiple projects at a time, then make a right click and select "properties". However this method only works for properties that were already exactly identical for the different projects : you can not use it in order to add an include path to a set of project that were using different include path.</li>
<li>I also know that it is possible to modify globally the environment options (Tools/Options/Project And solutions/Directories), however it is not that satisfying since it can not be integrated into a SCM</li>
<li>I also know that one can add "Configurations" to a solutions. It does not helps since it makes another set of project properties to maintain</li>
<li>I know that codegear C++ Builder 2009 offers a viable answer to this need through so called "Option sets" which can be inherited by several projects (I use both Visual Studio and C++ Builder, and I still thinks C++ Builder rocks on certain aspects as compared to Visual Studio) </li>
<li>I expect that someone will suggest an "autconf" such as CMake, however is it possible to import vcproj files into such a tool?</li>
</ul>

<p>I'm currently convering my ASP.NET v2 application to serialize/deserialize it's objects because I want to shift from inproc session state to stateserver. This is because my host, webhost4life, has a nasty tendency to recycle the worker process frequently thus causing session timeouts. Anyway... the question...</p>
<p>I'm trying to not serialize things I don't need to, i.e. variables that are re-initialised each page, don't need to be serialised. Here's one of them:</p>
<p> Private RollbackQueue As New Queue(Of DataServer.Rollback)</p>
<p>On deserialisation, will RollbackQueue be a) nothing or b) an empty queue? My guess is that when .NET deserialises, it creates the parent object as normal and then fills in the fields one by one. Therefore, the NEW bit will fire.</p>
<p>But that is a guess.</p>
<p>Thanks, Rob.</p>

<p>Does anyone have any advice for a consistent way to unit test a multithreaded application? I have done one application where our mock "worker threads" had a thread.sleep with a time that was specified by a public member variable. We would use this so we could set how long a particular thread would take to complete its work, then we could do our assertions. Any ideas of a better way to do this? Any good mock frameworks for .Net that can handle this?</p>

<p>Is it absolutely critical that I always close Syslog when I'm done using it? Is there a huge negative impact from not doing so?</p>
<p>If it turns out that I definitely need to, what's a good way to do it? I'm opening Syslog in my class constructor and I don't see a way to do class destructors in Ruby, and currently have something resembling this:</p>
<pre><code>class Foo
def initialize
@@log = Syslog.open("foo")
end
end
</code></pre>
<p>I don't immediately see the place where the <code>Syslog.close</code> call should be, but what do you recommend?</p>

<p>It's the weekend, so I relax from spending all week programming by writing a hobby project.</p>
<p>I wrote the framework of a MOS 6502 CPU emulator yesterday, the registers, stack, memory and all the opcodes are implemented. (Link to source below)</p>
<p>I can manually run a series of operations in the debugger I wrote, but I'd like to load a NES rom and just point the program counter at its instructions, I figured that this would be the fastest way to find flawed opcodes.</p>
<p>I wrote a quick NES rom loader and loaded the ROM banks into the CPU memory.</p>
<p>The problem is that I don't know how the opcodes are encoded. I know that the opcodes themselves follow a pattern of one byte per opcode that uniquely identifies the opcode, </p>
<pre><code>0 - BRK
1 - ORA (D,X)
2 - COP b
</code></pre>
<p>etc</p>
<p>However I'm not sure where I'm supposed to find the opcode argument. Is it the the byte directly following? In absolute memory, I suppose it might not be a byte but a short. </p>
<p>Is anyone familiar with this CPU's memory model?</p>
<p>EDIT: I realize that this is probably shot in the dark, but I was hoping there were some oldschool Apple and Commodore hackers lurking here.</p>
<p><strong>EDIT:</strong> Thanks for your help everyone. After I implemented the proper changes to align each operation the CPU can load and run Mario Brothers. It doesn't do anything but loop waiting for Start, but its a good sign :)</p>
<p>I uploaded the source:</p>
<p><a href="https://archive.codeplex.com/?p=cpu6502" rel="nofollow noreferrer">https://archive.codeplex.com/?p=cpu6502</a></p>
<p>If anyone has ever wondered how an emulator works, its pretty easy to follow. Not optimized in the least, but then again, I'm emulating a CPU that runs at 2mhz on a 2.4ghz machine :)</p>

<p>I am encountering very infrequent yet annoying SQL deadlocks on a .NET 2.0 webapp running on top of MS SQL Server 2005. In the past, we have been dealing with the SQL deadlocks in the very empirical way - basically tweaking the queries until it work.</p>
<p>Yet, I found this approach very unsatisfactory: time consuming and unreliable. I would highly prefer to follow deterministic query patterns that would ensure <strong>by design</strong> that no SQL deadlock will be encountered - ever.</p>
<p>For example, in C# multithreaded programming, a simple design rule such as <em>the locks must be taken following their lexicographical order</em> ensures that no deadlock will <em>ever</em> happen.</p>
<p>Are there any SQL coding patterns guaranteed to be deadlock-proof?</p>

<ul>
<li>The GoDiagram object model has a GoDocument. </li>
<li>GoViews have a reference to a GoDocument.</li>
<li>If the user does any modification on the diagramming surface, a GoDocument.Changed event is raised with the relevant information in the event arguments.</li>
</ul>
<p>I would like to be notified when some user-actions happen, so that I can confer with my Controller (disallow/cancel it if need be) and then issue view-update orders from there that actually modify the <strong>Northwoods GoDiagram</strong> third party component.<br>
The Changed event is a notification that something just happened (past tense) - Doing all of the above in the event handler results in a .... (<em>wait for it</em>)... StackOverflowException. (GoDocument.Changed handler > Updates GoDocument > Firing new Changed events.. )</p>
<p>So question, how do I get a BeforeEditing or BeforeResizing kind of notification model in GoDiagrams? Has anyone who's been there lived to tell a tale?</p>

<p>I searched the net and handbook, but I only managed to learn what is the masked package, and not how to install it. I did find some commands, but they don't seem to work on 2008 (looking at it, it seems those are for earlier versions). I have something like this:</p>
<pre><code>localhost ~ # emerge flamerobin
Calculating dependencies
!!! All ebuilds that could satisfy "dev-db/flamerobin" have been masked.
!!! One of the following masked packages is required to complete your request:
- dev-db/flamerobin-0.8.6 (masked by: ~x86 keyword)
- dev-db/flamerobin-0.8.3 (masked by: ~x86 keyword)
</code></pre>
<p>I would like to install version 0.8.6, but don't know how? I found some instructions, but they tell me to edit or write to some files under /etc/portage. However, I don't have /etc/portage on my system:</p>
<pre><code>localhost ~ # ls /etc/portage
ls: cannot access /etc/portage: No such file or directory
</code></pre>

<p>What is the best practice for naming UI controls (textboxes, drop-downs, etc.) on forms and reports for reference in the code-behind pages?</p>
<p>I develop a lot of reports and forms in my office. I have several web applications providing about 80+ "live" reports being generated from various and multiple data sources (Access, SQL, Oracle). These reports are considered "live" because they accept user set paramaters from a form, then query the database to produce a report based on the current information available.</p>
<p>So, the process starts with obtaining the values set by the user, passing those to the database query, receiving the dataset, and finally assigning the dataset to the report. In some cases, additional fields displayed on the report need to be calculated from the dataset before the report can be generated. This requires referencing the output controls on the report to assign the calculated value.</p>
<p>While I don't really care to use prefixes in my code for variables or member fields, I do use them to identify the UI controls. For example, txtFirstName to reference the report control to assign the data from the FirstName field in the dataset to the display control on the report. Is there a better practice for naming/referencing UI controls on forms and reports?</p>

<p>What tools do you use to develop Oracle stored procedures, in a team :</p>
<ul>
<li>To automatically "lock" the current procedure you are working with, so nobody else in the team can make changes to it until you are finished.</li>
<li>To automatically send the changes you make in the stored procedure, in an Oracle database, to a Subversion, CVS, ... repository</li>
</ul>
<p>Thanks!</p>

<p>In Cocoa, if I want to loop through an NSMutableArray and remove multiple objects that fit a certain criteria, what's the best way to do this without restarting the loop each time I remove an object?</p>
<p>Thanks,</p>
<p>Edit: Just to clarify - I was looking for the best way, e.g. something more elegant than manually updating the index I'm at. For example in C++ I can do;</p>
<pre><code>iterator it = someList.begin();
while (it != someList.end())
{
if (shouldRemove(it))
it = someList.erase(it);
}
</code></pre>

<p>I use a <code>System.Timers.Timer</code> in my Asp.Net application and I need to use the <code>HttpServerUtility.MapPath</code> method which seems to be only available via <code>HttpContext.Current.Server.MapPath</code>.
The problem is that <code>HttpContext.Current</code> is <code>null</code> when the <code>Timer.Elapsed</code> event fires.</p>
<p>Is there another way to get a reference to a HttpServerUtility object ?
I could inject it in my class' constructor. Is it safe ? How can I be sure it won't be Garbage Collected at the end of the current request?</p>
<p>Thanks!</p>

<p>I can print with <code>printf</code> as a hex or octal number. Is there a format tag to print as binary, or arbitrary base?</p>
<p>I am running gcc.</p>
<pre><code>printf("%d %x %o\n", 10, 10, 10); //prints "10 A 12\n"
print("%b\n", 10); // prints "%b\n"
</code></pre>

<p>I know what Hungarian refers to - giving information about a variable, parameter, or type as a prefix to its name. Everyone seems to be rabidly against it, even though in some cases it seems to be a good idea. If I feel that useful information is being imparted, why shouldn't I put it right there where it's available?</p>
<p>See also: <a href="https://stackoverflow.com/questions/5428/do-people-use-the-hungarian-naming-conventions-in-the-real-world">Do people use the Hungarian naming conventions in the real world?</a> </p>

<p>You can use ftplib for full FTP support in Python. However the preferred way of getting a directory listing is:</p>
<pre><code># File: ftplib-example-1.py
import ftplib
ftp = ftplib.FTP("www.python.org")
ftp.login("anonymous", "ftplib-example-1")
data = []
ftp.dir(data.append)
ftp.quit()
for line in data:
print "-", line
</code></pre>
<p>Which yields:</p>
<pre><code>$ python ftplib-example-1.py
- total 34
- drwxrwxr-x 11 root 4127 512 Sep 14 14:18 .
- drwxrwxr-x 11 root 4127 512 Sep 14 14:18 ..
- drwxrwxr-x 2 root 4127 512 Sep 13 15:18 RCS
- lrwxrwxrwx 1 root bin 11 Jun 29 14:34 README -> welcome.msg
- drwxr-xr-x 3 root wheel 512 May 19 1998 bin
- drwxr-sr-x 3 root 1400 512 Jun 9 1997 dev
- drwxrwxr-- 2 root 4127 512 Feb 8 1998 dup
- drwxr-xr-x 3 root wheel 512 May 19 1998 etc
...
</code></pre>
<p>I guess the idea is to parse the results to get the directory listing. However this listing is directly dependent on the FTP server's way of formatting the list. It would be very messy to write code for this having to anticipate all the different ways FTP servers might format this list.</p>
<p>Is there a portable way to get an array filled with the directory listing?</p>
<p>(The array should only have the folder names.)</p>

<p>Is there a way to separate a C# class into a header that contains the class definition and then an actual .cs file that contains the implementation? I suppose one can do this by creating an interface, but that doesn't seem right. I just want a file where I can just see the class design, and not all the detail. It's easy enough to do in C++, but I haven't seen it done with C#.</p>
<p>Thanks in advance.</p>

<p>How to enable inno-db support on installed instance of MySql?</p>
<p>I have installed mysql-5.0.67-win32.
'InnoDB' is 'DISABLED' when executing 'show engines'.
According to documentation MySql is compiled with support of inno-db
(From doc: A value of DISABLED occurs either because the server was started with an option that disables the engine, or because not all options required to enable it were given.)</p>
<p>In my.ini I commented line with 'skip-innodb'. This didn't help.
All other inno-db related variables remain unchanged.</p>
<p>I have performed some unusual action before I experienced described situation.
I have mysql-4.0.17-win installed. I uninstall it and after this installed mysql-5.0.67-win32.
In installation wizard I chose MyISAM support only (as far as I understand I disabled inno-db support in such way. When I tried to reinstall with support of inno-db I had problems of using my previous database 'mysql' with account information).</p>
<p>MySQL documentation says that I should use mysqldump to export data and after this to import exported data in process of upgrade. I tried to do so, but when importing data I obtained message about syntax error (I think that it is connected with some incompatibilities of 4-th and 5-th version of mysql)</p>

<p>I'm using the AdvancedDataGrid widget and I want two columns to be radio buttons, where each column is it's own RadioButtonGroup. I thought I had all the necessary mxxml, but I'm running into a strange behavior issue. When I scroll up and down, the button change values!

<p><em>UPDATED</em> (thanks bill!)</p>
<p>Alright! Go it working. I just had to make a couple of changes from bill's suggestion. Mainly using ArrayCollection with ObjectProxy so it was both bindable and dynamic. One weird thing - I couldn't select a button in the first row if I filled in the array at construction time; I had to delay that until the creationComplete event was fired (which is fine, since I'm going to populate the grid from a db anyway).</p>

<p>I'm looking at a batch file which defines the following variables:</p>
<pre><code>set _SCRIPT_DRIVE=%~d0
set _SCRIPT_PATH=%~p0
</code></pre>
<ul>
<li>What do <code>%~d0</code> or <code>%~p0</code> actually mean?</li>
<li>Is there a set of well-known values for things like current directory, drive, parameters to a script?</li>
<li>Are there any other similar shortcuts I could use?</li>
</ul>

<p>The word seems to get used in a number of contexts. The best I can figure is that they mean a variable that can't change. Isn't that what constants/finals (darn you Java!) are for?</p>

<p>Instead of having to remember to initialize a simple 'C' structure, I might derive from it and zero it in the constructor like this:</p>
<pre><code>struct MY_STRUCT
{
int n1;
int n2;
};
class CMyStruct : public MY_STRUCT
{
public:
CMyStruct()
{
memset(this, 0, sizeof(MY_STRUCT));
}
};
</code></pre>
<p>This trick is often used to initialize Win32 structures and can sometimes set the ubiquitous <strong>cbSize</strong> member.</p>
<p>Now, as long as there isn't a virtual function table for the memset call to destroy, is this a safe practice?</p>

<p>I have a simple list I am using for a horizontal menu:</p>
<pre><code><ul>
<h1>Menu</h1>
<li>
<a href="/" class="selected">Home</a>
</li>
<li>
<a href="/Home">Forum</a>
</li>
</ul>
</code></pre>
<p>When I add a background color to the selected class, only the text gets the color, I want it to stretch the entire distance of the section.</p>
<p>Hope this makes sense.</p>

<p>In terms of quick dynamically typed languages, I'm really starting to like Javascript, as I use it a lot for web projects, especially because it uses the same syntax as Actionscript (flash).</p>
<p>It would be an ideal language for shell scripting, making it easier to move code from the front and back end of a site, and less of the strange syntax of python.</p>
<p>Is there a good, javascript interpreter that is easy to install (I know there's one based on java, but that would mean installing all the java stuff to use), </p>

<p>I currently have a Java SAX parser that is extracting some info from a 30GB XML file. </p>
<p>Presently it is:</p>
<ul>
<li>reading each XML node</li>
<li>storing it into a string object, </li>
<li>running some regexex on the string</li>
<li>storing the results to the database</li>
</ul>
<p>For several million elements. I'm running this on a computer with 16GB of memory, but the memory is not being fully utilized. </p>
<p>Is there a simple way to dynamically 'buffer' about 10gb worth of data from the input file? </p>
<p>I suspect I could manually take a 'producer' 'consumer' multithreaded version of this (loading the objects on one side, using them and discarding on the other), but damnit, XML is ancient now, are there no efficient libraries to crunch em?</p>

<p>On my team, we usually do string concatentation like this:</p>
<pre><code>var url = // some dynamically generated URL
var sb = new StringBuffer();
sb.append("<a href='").append(url).append("'>click here</a>");
</code></pre>
<p>Obviously the following is much more readable:</p>
<pre><code>var url = // some dynamically generated URL
var sb = "<a href='" + url + "'>click here</a>";
</code></pre>
<p>But the JS experts claim that the <code>+</code> operator is less performant than <code>StringBuffer.append()</code>. Is this really true?</p>

<p>For years I've been using ShellExecute() API to launch the default web browser from within my applications. Like this:</p>
<pre><code>ShellExecute( hwnd, _T("open"),
_T("http://www.winability.com/home/"),
NULL, NULL, SW_NORMAL );
</code></pre>
<p>It's been working fine until a couple of weeks ago, when Google released its Chrome browser. Now, if Chrome is installed on the computer, the ShellExecute API no longer opens a web page.</p>
<p>Has anyone figured out yet how to solve this problem? (Short of detecting Chrome and displaying a message telling the user it's Chrome's fault?)</p>
<p>EDIT: the code provided by Sergey seems to work, so I've accepted it as "the" answer. Except that I don't like the call to WinExec: MSDN reads that WinExec is provided only for compatibility with 16-bit applications. IOW, it may stop working with any Service Pack. I did not try it, but I would not be surprised if it has already stopped working with Windows x64, since it does not support 16-bit applications at all. So, instead of WinExec, I'm going to use ShellExecute, with the path taken from the registry like Sergey's code does, and the URL as the argument. Thanks! </p>

<p>I want to create a hidden field and create a link in one helper and then output both to my erb.</p>
<pre><code><%= my_cool_helper "something", form %>
</code></pre>
<p>Should out put the results of</p>
<pre><code>link_to "something", a_path
form.hidden_field "something".tableize, :value => "something"
</code></pre>
<p>What would the definition of the helper look like? The details of what link_to and the form.hidden_field don't really matter. What matters is, how do I return the output from two different calls.</p>

<p>I made a panel and set it to fill the screen, now I can see the windows under it but I want it to be click through, meaning they could click a file or see a tool tip of another object through the transparency.</p>
<blockquote>
<blockquote>
<p>RE: This may be too obvious, but have you tried sending the panel to the back by right clicking and choosing "Send to Back"?</p>
</blockquote>
</blockquote>
<p>I mean like the desktop or firefox, not something within my project.</p>

<p>Let's say that I have two arrays (in Java),</p>
<p>int[] numbers; and int[] colors;</p>
<p>Each ith element of numbers corresponds to its ith element in colors.
Ex, numbers = {4,2,1}
colors = {0x11, 0x24, 0x01}; Means that number 4 is color 0x11, number 2 is 0x24, etc.</p>
<p>I want to sort the numbers array, but then still have it so each element matches up with its pair in colors.</p>
<p>Ex. numbers = {1,2,4};
colors = {0x01,0x24,0x11};</p>
<p>What's the cleanest, simplest way to do this? The arrays have a few thousand items, so being in place would be best, but not required. Would it make sense to do an Arrays.sort() and a custom comparator? Using library functions as much as possible is preferable.</p>
<p><strong>Note: I know the "best" solution is to make a class for the two elements and use a custom comparator. This question is meant to ask people for the quickest way to code this. Imagine being at a programming competition, you wouldn't want to be making all these extra classes, anonymous classes for the comparator, etc. Better yet, forget Java; how would you code it in C?</strong></p>

<p>There are certain Crystal Reports features that cannot be combined in the same report, for example SQL command objects and server side grouping. However, as far as I can find, the built-in help doesn't seem to clearly document these conflicts. For example, checking the help page for either of those features doesn't mention that it doesn't work with the other. I want to be able to find out about these conflicts when I decide to use a new feature, not later when I go to use some other feature and the option is greyed out. Is there any place that documents these conflicts?</p>
<p>I am specifically working with Crystal Reports XI. Bonus points if the list of conflicts documents what range of versions each feature is available and conflicting in.</p>
<p>I have now also checked the release notes (release.pdf on install CD), and it does not have any answers to this question.</p>

<p>I have a very large database table in PostgresQL and a column like "copied". Every new row starts uncopied and will later be replicated to another thing by a background programm. There is an partial index on that table "btree(ID) WHERE replicated=0". The background programm does a select for at most 2000 entries (LIMIT 2000), works on them and then commits the changes in one transaction using 2000 prepared sql-commands.</p>
<p>Now the problem ist that I want to give the user an option to reset this replicated-value, make it all zero again.</p>
<p>An update table set replicated=0;</p>
<p>is not possible:</p>
<ul>
<li>It takes very much time</li>
<li>It duplicates the size of the tabel because of MVCC</li>
<li>It is done in one transaction: It either fails or goes through.</li>
</ul>
<p>I actually don't need transaction-features for this case: If the system goes down, it shall process only parts of it.</p>
<p>Several other problems:
Doing an </p>
<pre><code>update set replicated=0 where id >10000 and id<20000
</code></pre>
<p>is also bad: It does a sequential scan all over the whole table which is too slow.
If it weren't doing that, it would still be slow because it would be too many seeks.</p>
<p>What I really need is a way of going through all rows, changing them and not being bound to a giant transaction.</p>
<p>Strangely, an</p>
<pre><code>UPDATE table
SET replicated=0
WHERE ID in (SELECT id from table WHERE replicated= LIMIT 10000)
</code></pre>
<p>is also slow, although it should be a good thing: Go through the table in DISK-order...</p>
<p>(Note that in that case there was also an index that covered this)</p>
<p>(An update LIMIT like Mysql is unavailable for PostgresQL)</p>
<p>BTW: The real problem is more complicated and we're talking about an embedded system here that is already deployed, so remote schema changes are difficult, but possible
It's PostgresQL 7.4 unfortunately.</p>
<p>The amount of rows I'm talking about is e.g. 90000000. The size of the databse can be several dozend gigabytes.</p>
<p>The database itself only contains 5 tables, one is a very large one.
But that is not bad design, because these embedded boxes only operate with one kind of entity, it's not an ERP-system or something like that!</p>
<p>Any ideas?</p>

<p>Static metaprogramming (aka "template metaprogramming") is a great C++ technique that allows the execution of programs at compile-time. A light bulb went off in my head as soon as I read this canonical metaprogramming example:</p>
<pre><code>#include <iostream>
using namespace std;
template< int n >
struct factorial { enum { ret = factorial< n - 1 >::ret * n }; };
template<>
struct factorial< 0 > { enum { ret = 1 }; };
int main() {
cout << "7! = " << factorial< 7 >::ret << endl; // 5040
return 0;
}
</code></pre>
<p>If one wants to learn more about C++ static metaprogramming, what are the best sources (books, websites, on-line courseware, whatever)?</p>

<p>I am a fan of <a href="https://stackoverflow.com/questions/112277/best-intro-to-c-static-metaprogramming">static metaprogramming in C++</a>. I know Java now has generics. Does this mean that static metaprogramming (i.e., compile-time program execution) is possible in Java? If so, can anyone recommend any good resources where one can learn more about it?</p>

<p>I set a passphrase when creating a new SSH key on my laptop. But, as I realise now, this is quite painful when you are trying to commit (<a href="http://en.wikipedia.org/wiki/Git_%28software%29" rel="noreferrer">Git</a> and <a href="http://en.wikipedia.org/wiki/Apache_Subversion" rel="noreferrer">SVN</a>) to a remote location over SSH many times in an hour.</p>
<p>One way I can think of is, delete my SSH keys and create new. Is there a way to remove the passphrase, while still keeping the same keys?</p>

<p>I would like to use Visual Studio 2008 to the greatest extent possible while effectively compiling/linking/building/etc code as if all these build processes were being done by the tools provided with MASM 6.11. The exact version of MASM does not matter, so long as it's within the 6.x range, as that is what my college is using to teach 16-bit assembly.</p>
<p>I have done some research on the subject and have come to the conclusion that there are several options:</p>
<ol>
<li>Reconfigure VS to call the MASM 6.11 executables with the same flags, etc as MASM 6.11 would natively do.</li>
<li>Create intermediary batch file(s) to be called by VS to then invoke the proper commands for MASM's linker, etc.</li>
<li>Reconfigure VS's built-in build tools/rules (assembler, linker, etc) to provide an environment identical to the one used by MASM 6.11.</li>
</ol>
<p>Option (2) was brought up when I realized that the options available in VS's "External Tools" interface may be insufficient to correctly invoke MASM's build tools, thus a batch file to interpret VS's strict method of passing arguments might be helpful, as a lot of my learning about how to get this working involved my manually calling ML.exe, LINK.exe, etc from the command prompt.</p>
<p>Below are several links that may prove useful in answering my question. Please keep in mind that I have read them all and none are the actual solution. I can only hope my specifying MASM 6.11 doesn't prevent anyone from contributing a perhaps more generalized answer.</p>
<p>Similar method used to Option (2), but users on the thread are not contactable:<br>
<a href="http://www.codeguru.com/forum/archive/index.php/t-284051.html" rel="nofollow noreferrer">http://www.codeguru.com/forum/archive/index.php/t-284051.html</a><br>
(also, I have my doubts about the necessity of an intermediary batch file)</p>
<p>Out of date explanation to my question:<br>
<a href="http://www.cs.fiu.edu/~downeyt/cop3402/masmaul.html" rel="nofollow noreferrer">http://www.cs.fiu.edu/~downeyt/cop3402/masmaul.html</a></p>
<p>Probably the closest thing I've come to a definitive solution, but refers to a suite of tools from something besides MASM, also uses a batch file:<br>
<a href="http://www.kipirvine.com/asm/gettingStarted/index.htm#16-bit" rel="nofollow noreferrer">http://www.kipirvine.com/asm/gettingStarted/index.htm#16-bit</a></p>
<p>I apologize if my terminology for the tools used in each step of the code -> exe process is off, but since I'm trying to reproduce the entirety of steps in between completion of writing the code and generating an executable, I don't think it matters much.</p>

<p>In a C++ project I'm working on, I have a <em>flag</em> kind of value which can have four values. Those four flags can be combined. Flags describe the records in database and can be:</p>
<ul>
<li>new record</li>
<li>deleted record</li>
<li>modified record</li>
<li>existing record</li>
</ul>
<p>Now, for each record I wish to keep this attribute, so I could use an enum:</p>
<pre><code>enum { xNew, xDeleted, xModified, xExisting }
</code></pre>
<p>However, in other places in code, I need to select which records are to be visible to the user, so I'd like to be able to pass that as a single parameter, like: </p>
<pre><code>showRecords(xNew | xDeleted);
</code></pre>
<p>So, it seems I have three possible appoaches:</p>
<pre><code>#define X_NEW 0x01
#define X_DELETED 0x02
#define X_MODIFIED 0x04
#define X_EXISTING 0x08
</code></pre>
<p>or</p>
<pre><code>typedef enum { xNew = 1, xDeleted, xModified = 4, xExisting = 8 } RecordType;
</code></pre>
<p>or </p>
<pre><code>namespace RecordType {
static const uint8 xNew = 1;
static const uint8 xDeleted = 2;
static const uint8 xModified = 4;
static const uint8 xExisting = 8;
}
</code></pre>
<p>Space requirements are important (byte vs int) but not crucial. With defines I lose type safety, and with <code>enum</code> I lose some space (integers) and probably have to cast when I want to do a bitwise operation. With <code>const</code> I think I also lose type safety since a random <code>uint8</code> could get in by mistake.</p>
<p>Is there some other cleaner way?</p>
<p>If not, what would you use and why?</p>
<p>P.S. The rest of the code is rather clean modern C++ without <code>#define</code>s, and I have used namespaces and templates in few spaces, so those aren't out of question either.</p>

<p>If you had read my other <a href="https://stackoverflow.com/questions/111700/6502-cpu-emulation">question</a>, you'll know I've spent this weekend putting together a 6502 CPU emulator as a programming exercise.</p>
<p>The CPU emulator is mostly complete, and seems to be fairly accurate from my limited testing, however it is running incredibly fast, and I want to throttle it down to the actual clock speed of the machine.</p>
<p>My current test loop is this:</p>
<pre><code> // Just loop infinitely.
while (1 == 1)
{
CPU.ClockCyclesBeforeNext--;
if (CPU.ClockCyclesBeforeNext <= 0)
{
// Find out how many clock cycles this instruction will take
CPU.ClockCyclesBeforeNext = CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].CpuCycles;
// Run the instruction
CPU.ExecuteInstruction(CPU.Memory[CPU.PC]);
// Debugging Info
CPU.DumpDebug();
Console.WriteLine(CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].ArgumentLength);
// Move to next instruction
CPU.PC += 1 + CPU.OpcodeMapper.Map[CPU.Memory[CPU.PC]].ArgumentLength;
}
}
</code></pre>
<p>As you can tell, each opcode takes a specific amount of time to complete, so I do not run the next instruction until I count down the CPU Cycle clock. This provides proper timing between opcodes, its just that the entire thing runs way to fast.</p>
<p>The targeted CPU speed is 1.79mhz, however I'd like whatever solution to the clock issue to keep the speed at 1.79mhz even as I add complexity, so I don't have to adjust it up.</p>
<p>Any ideas?</p>

a.src = b;
}
newImage("\/_layouts\/images\/icon1.gif");
newImage("\/_layouts\/images\/icon2.gif");
// -->
</SCRIPT>
</code></pre>
<p>The error I am getting is when clicking on a drop down context menu on a page, for this line:</p>
<pre><code>newImage("\/_layouts\/images\/icon1.gif");
</code></pre>
<blockquote>
<p>The object doesn't accept this property or method

<p>I really don't see what could happen... Any tips on what may be happening here?</p>

<p>For <code><script></code> HTML tags, what is the technical difference between <code>lang=Javascript</code> and <code>type=text/javascript</code>?</p>
<p>I usually use both, because I've always assumed that older browsers need one or the other.</p>

<p>I'm specifically looking for one that lets me display a map of US states with each one as it's own "object" in the sense that I can control the color, on click, and on mouseover of each one individually. GTK is my personal preference, but at this point I'd settle for just about anything. The application itself will be written in Python, FWIW.</p>

<p>Given an array of <strong>n</strong> Objects, let's say it is an <strong>array of strings</strong>, and it has the following values:</p>
<pre><code>foo[0] = "a";
foo[1] = "cc";
foo[2] = "a";
foo[3] = "dd";
</code></pre>
<p>What do I have to do to delete/remove all the strings/objects equal to <strong>"a"</strong> in the array?</p>

<p>I have the following enum:</p>
<pre><code>public enum Status implements StringEnum{
ONLINE("on"),OFFLINE("off");
private String status = null;
private Status(String status) {
this.status = status;
}
public String toString() {
return this.status;
}
public static Status find(String value) {
for(Status status : Status.values()) {
if(status.toString().equals(value)) {
return status;
}
}
throw new IllegalArgumentException("Unknown value: " + value );
}
}
</code></pre>
<p>Is it possible to build StringEnum interface to make sure every enum has find(), toString() and a constructor?</p>
<p>Thanks.</p>

<p>How would a go about making a program where the user enters a string, and the program generates a list of words beginning with that string?</p>
<p>Ex:<br />
User: "abd"<br />
Program:abdicate, abdomen, abduct...</p>
<p>Thanks!</p>

<p>Edit: I'm using python, but I assume that this is a fairly language-independent problem.</p>

<p>I have a table that contains tasks and I want to give these an explicit ordering based on the priority of the task. The only way I can think to do this is via an <strong>unique</strong> int column that indexes where the task is in term of the priority (i.e. 1 is top 1000 is low).</p>
<p>The problem is that say I wanted to update task and set its priority to a lower value , I would have to update all the other rows between its current value and its new value.</p>
<p><strong>Can anyone suggest a better way of implementing this?</strong></p>

<p>I recently discovered the genshi.builder module. It reminds me of Divmod Nevow's Stan module. How would one use genshi.builder.tag to build an HTML document with a particular doctype? Or is this even a good thing to do? If not, what is the <em>right</em> way?</p>

<p>I'm having a hard time understanding and therefore managing arrays and indexes manually in C. These are my two classic approaches but they doesn't seem to work as they keep looping when the condition is reached: </p>
<pre><code>#include<stdio.h>
#define MAX 255
int main(){
int arr[MAX]={0};
int idx=0;
/* Approach #1 */
printf("Enter elements, -1 to finish:\n");
scanf("%d", &arr[idx]);
while(arr[idx-1] != -1 && idx < MAX){
printf("Enter elements, -1 to finish:\n");
scanf("%d", &arr[idx]);
idx++;
}
/* Approach #2 */
do{
printf("Enter elements, -1 to finish:\n");
scanf("%d", &arr[idx]);
idx++;
}while(arr[idx-1] != -1 && idx < MAX);
// Main func continues here.
}
</code></pre>

<p>I want to select the topmost element in a document that has a given namespace (prefix).</p>
<p>More specifically: I have XML documents that either start with /html/body (in the XHTML namespace) or with one of several elements in a particular namespace. I effectively want to strip out /html/body and just return the body contents OR the entire root namespaced element. </p>

<p>I am using jProfiler to find memory leaks in a Java swing application. I have identified instances of a JFrame which keeps growing in count.</p>
<p>This frame is opened, and then closed.</p>
<p>Using jProfiler, and viewing the Paths to GC Root there is only one reference, 'JNI Global reference'.</p>
<p>What does this mean? Why is it hanging on to each instance of the frame?</p>

<p>I am hosting <a href="http://developer.mozilla.org/En/SpiderMonkey/JSAPI_Reference" rel="nofollow noreferrer">SpiderMonkey</a> in a current project and would like to have template functions generate some of the simple property get/set methods, eg:</p>
<pre><code>template <typename TClassImpl, int32 TClassImpl::*mem>
JSBool JS_DLL_CALLBACK WriteProp(JSContext* cx, JSObject* obj, jsval id, jsval* vp)
{
if (TClassImpl* pImpl = (TClassImpl*)::JS_GetInstancePrivate(cx, obj, &TClassImpl::s_JsClass, NULL))
return ::JS_ValueToInt32(cx, *vp, &(pImpl->*mem));
return JS_FALSE;
}
</code></pre>
<p>Used:</p>
<pre><code>::JSPropertySpec Vec2::s_JsProps[] = {
{"x", 1, JSPROP_PERMANENT, &JsWrap::ReadProp<Vec2, &Vec2::x>, &JsWrap::WriteProp<Vec2, &Vec2::x>},
{"y", 2, JSPROP_PERMANENT, &JsWrap::ReadProp<Vec2, &Vec2::y>, &JsWrap::WriteProp<Vec2, &Vec2::y>},
{0}
};
</code></pre>
<p>This works fine, however, if I add another member type:</p>
<pre><code>template <typename TClassImpl, JSObject* TClassImpl::*mem>
JSBool JS_DLL_CALLBACK WriteProp(JSContext* cx, JSObject* obj, jsval id, jsval* vp)
{
if (TClassImpl* pImpl = (TClassImpl*)::JS_GetInstancePrivate(cx, obj, &TClassImpl::s_JsClass, NULL))
return ::JS_ValueToObject(cx, *vp, &(pImpl->*mem));
return JS_FALSE;
}
</code></pre>
<p>Then Visual C++ 9 attempts to use the JSObject* wrapper for int32 members!</p>
<pre><code>1>d:\projects\testing\jswnd\src\main.cpp(93) : error C2440: 'specialization' : cannot convert from 'int32 JsGlobal::Vec2::* ' to 'JSObject *JsGlobal::Vec2::* const '
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
1>d:\projects\testing\jswnd\src\main.cpp(93) : error C2973: 'JsWrap::ReadProp' : invalid template argument 'int32 JsGlobal::Vec2::* '
1> d:\projects\testing\jswnd\src\wrap_js.h(64) : see declaration of 'JsWrap::ReadProp'
1>d:\projects\testing\jswnd\src\main.cpp(93) : error C2440: 'initializing' : cannot convert from 'overloaded-function' to 'JSPropertyOp'
1> None of the functions with this name in scope match the target type
</code></pre>
<p>Surprisingly, parening JSObject* incurs a parse error! (unexpected '('). This is probably a VC++ error (can anyone test that "template void foo() {}" compiles in GCC?). Same error with "typedef JSObject* PObject; ..., PObject TClassImpl::<em>mem>", void</em>, struct Undefined*, and double. Since the function usage is fully instantiated: "&ReadProp", there should be no normal function overload semantics coming into play, it is a defined function at that point and gets priority over template functions. It seems the template ordering is failing here.</p>
<p>Vec2 is just:</p>
<pre><code>class Vec2
{
public:
int32 x, y;
Vec2(JSContext* cx, JSObject* obj, uintN argc, jsval* argv);
static ::JSClass s_JsClass;
static ::JSPropertySpec s_JsProps[];
};
</code></pre>
<p>JSPropertySpec is described in JSAPI link in OP, taken from header:</p>
<pre><code>typedef JSBool
(* JS_DLL_CALLBACK JSPropertyOp)(JSContext *cx, JSObject *obj, jsval id,
jsval *vp);
...
struct JSPropertySpec {
const char *name;
int8 tinyid;
uint8 flags;
JSPropertyOp getter;
JSPropertyOp setter;
};
</code></pre>

<p>So, when I was a comparative novice to the novice I am right now, I used to think that these two things were syntactic sugar for each other, i.e. that using one over the other was simply a personal preference. Over time, I'm come to find that these two are not the same thing, even in a default implementation (see <a href="http://web.archive.org/web/20081205081158/http://blogs.msdn.com:80/jmstall/archive/2005/03/06/386064.aspx" rel="nofollow noreferrer">this</a> and <a href="http://web.archive.org/web/20090710210823/http://blogs.msdn.com:80/jmstall/archive/2005/03/12/394645.aspx" rel="nofollow noreferrer">this</a>). To further confuse the matter, each can be overridden/overloaded separately to have completely different meanings. </p>
<p>Is this a good thing, what are the differences, and when/why should you use one over the other?</p>

<p>I know how to create a <code>SEL</code> at compile time using <code>@selector(MyMethodName:)</code> but what I want to do is create a selector dynamically from an <code>NSString</code>. Is this even possible?</p>
<p>What I can do:</p>
<pre><code>SEL selector = @selector(doWork:);
[myobj respondsToSelector:selector];
</code></pre>
<p>What I want to do: (pseudo code, this obviously doesn't work)</p>
<pre><code>SEL selector = selectorFromString(@"doWork");
[myobj respondsToSelector:selector];
</code></pre>
<p>I've been searching the Apple API docs, but haven't found a way that doesn't rely on the compile-time <code>@selector(myTarget:)</code> syntax.</p>

<p>One of the many things that's been lacking from my <a href="https://stackoverflow.com/questions/61553/track-your-reputation">scraper service</a> that I set up last week are pretty URLs. Right now the user parameter is being passed into the script with <em>?u=</em>, which is a symptom of a lazy hack (which the script admittedly is). However, I've been thinking about redoing it and I'd like to get some feedback on the options available. Right now there are two pages, update and chart, that provide information to the user. Here are the two possibilities that I came up with. "1234" is the user ID number. For technical reasons the user name unfortunately cannot be used:</p>
<ul>
<li>http://< tld >/update/1234</li>
<li>http://< tld >/chart/1234</li>
</ul>
<p>or</p>
<ul>
<li>http://< tld >/1234/update</li>
<li>http://< tld >/1234/chart</li>
</ul>
<p>Option #1, conceptually, is calling update with the user ID. Option #2 is providing a verb to operate on a user ID.</p>
<p>From a consistency standpoint, which makes more sense?</p>
<hr>
<p>Another option mentioned is</p>
<ul>
<li>http://< tld >/user/1234/update</li>

<p>I thought I heard that <a href="http://www.py2exe.org/" rel="noreferrer">py2exe</a> was able to do this, but I never figured it out. Has anyone successfully done this? Can I see your setup.py file, and what command line options you used?</p>
<p>Basically I'm thinking of it giving me a single executable file that does something like unzips itself to maybe /temp and runs.</p>

<p>Whenever I indent <code>HTML</code> in <code>PHP</code> mode, <code>emacs (22.1.1, basic install on Redaht Linux over Putty-SSH)</code> pops up a frame and tells me to get <code>MUMODE</code> or <code>somesuch</code> extra add-on. I installed <code>PHP</code> Mode without a big hassle, but I don't know how to get this multi-mode rolling.<br>
<hr>
I'd like to know 2 things</p>
<pre><code>How to install and configure multi-mode
How to disable pop-ups in Emacs

<p>I've got the following situation</p>
<ul>
<li>A rails application that makes use of rjs / Scriptaculous to offer AJAX functionality</li>
<li>Lot of nice javascript written using jQuery (for a separate application)</li>
</ul>
<p>I want to combine the two and use my jQuery based functionality in my Rails application, but I'm worried about jQuery and Scriptaculous clashing (they both define the $() function, etc). </p>
<p>What is my easiest option to bring the two together? Thanks!</p>

<p>I have a <code>n...n</code> structure for two tables, <strong><code>makes</code></strong> and <strong><code>models</code></strong>. So far no problem.</p>
<p>In a third table (<strong><code>products</code></strong>) like:</p>
<pre><code>id
make_id
model_id
...
</code></pre>
<p>My problem is creating a view for products of one specifi <strong><code>make</code></strong> inside my <code>ProductsController</code> containing just that's make models:</p>
<p>I thought this could work:</p>
<pre><code>var $uses = array('Make', 'Model');
$this->Make->id = 5; // My Make
$this->Make->find(); // Returns only the make I want with it's Models (HABTM)
$this->Model->find('list'); // Returns ALL models
$this->Make->Model->find('list'); // Returns ALL models
</code></pre>
<p>So, If I want to use the <code>list</code> to pass to my view to create radio buttons I will have to do a <code>foreach()</code> in my <strong><code>make</code></strong> array to find all models titles and create a new array and send to the view via <code>$this->set()</code>.</p>
<pre><code>$makeArray = $this->Make->find();
foreach ($makeArray['Model'] as $model) {
$modelList[] = $model['title'];
}
$this->set('models', $models)
</code></pre>
<p>Is there any easier way to get that list without stressing the <strong><code>make</code></strong> Array. It will be a commom task to develops such scenarios in my application(s).</p>
<p>Thanks in advance for any hint!</p>

<p>A Box Item may be defective:if it is, a flag will be set in the Box Item's row (IsDefective), and the Box Item will be put in a "Returns" box (with other items to be returned to that vendor). Otherwise, the Box Item will eventually be put into a "Shipping" box (with other items to be shipped). (Note that Shipping and Returns boxes have their own tables: there's not one common table for all boxes... though maybe I should consider doing that if possible as a third possibility?)</p>
<p>Maybe I'm just not thinking clearly today, but I started questioning what should be done in this situation.</p>
<p>My gut tells me that I should have a separate field for each possible relation, even if only one of the relations can happen at any given time, which would make the schema for Box Items look like:</p>
<p>BoxItemID
Description
IsDefective
ShippingBoxID
ReturnBoxID
etc...</p>
<p>This would make the relations clear, but it seems wasteful (since only one of the relations will be used at any time). So then I thought I could have just one field for the BoxID, and determine which BoxID it's referring to (a Shipping or a Returns Box ID) based on the IsDefective field:</p>
<p>BoxItemID
Description
IsDefective
BoxID
etc...</p>
<p>This seems less wasteful, but doesn't sit right with me. The relation isn't obvious.</p>
<p>So, I put it to you, database gurus of Stackoverflow. What would you do in this situation?</p>
<p>EDIT: Thank you everyone for your input! It's given me a lot to think about. For one, I'm going to use an ORM next time I start a project like this. =) For two, since I'm not right now, I'll bite the four bytes and use two fields.</p>
<p>Thanks everyone again!</p>

<p>Is there a way to view the key/value pairs of a NSDictionary variable through the Xcode debugger? Here's the extent of information when it is fully expanded in the variable window:</p>
<pre><code>Variable Value Summary
jsonDict 0x45c540 4 key/value pairs
NSObject {...}
isa 0xa06e0720
</code></pre>
<p>I was expecting it to show me each element of the dictionary (similar to an array variable). </p>

<p>How do I access parameters passed into an Oracle Form via a URL.
Eg given the url:</p>
<blockquote>
<p><a href="http://example.com/forms90/f90servlet?config=cust&form=" rel="nofollow noreferrer">http://example.com/forms90/f90servlet?config=cust&form=</a>'a_form'&p1=something&p2=else</p>
</blockquote>
<p>This will launch the 'a_form' form, using the 'cust' configuration, but I can't work how (or even if it's possible) to access p1 (with value of 'something') p2 (with value of 'else')</p>
<p>Does anyone know how I can do this? (Or even if it is/isn't possible?</p>
<p>Thanks</p>

<p>I am creating a standalone asp.net page that needs to be embedded into a sharepoint site using the Page Viewer Web Part. The asp.net page is published to the same server on a different port, giving me the URL to embed.</p>
<p>The requirement is that after a user is authenticated using Sharepoint authentication, they navigate to a page containing the asp.net web part for more options. </p>
<p>What I need to do from this asp.net page is query Sharepoint for the currently authenticated username, then display this on the page from the asp.net code. </p>
<p>This all works fine when I debug the application from VS, but when published and displayed though Sharepoint, I always get NULL as the user. </p>
<p>Any suggestions on the best way to get this to work would be much appreciated.</p>

<p>Sometimes my c++ program crashes in debug mode, and what I got is a message box saying that an assertion failed in some of the internal memory management routines (accessing unallocated memory etc.). But I don't know where that was called from, because I didn't get any stack trace. How do I get a stack trace or at least see where it fails in my code (instead of library/ built-in routines)?</p>

<p>According to the documentation the return value from a slot doesn't mean anything.<br>
Yet in the generated moc code I see that if a slot returns a value this value is used for something. Any idea what does it do?</p>
<hr>
<p>Here's an example of what I'm talking about. this is taken from code generated by moc. 'message' is a slot that doesn't return anything and 'selectPart' is declared as returning int.</p>
<pre><code>case 7: message((*reinterpret_cast< const QString(*)>(_a[1])),(*reinterpret_cast< int(*)>(_a[2]))); break;
case 8: { int _r = selectPart((*reinterpret_cast< AppObject*(*)>(_a[1])),(*reinterpret_cast< int(*)>(_a[2])));
if (_a[0]) *reinterpret_cast< int*>(_a[0]) = _r; } break;
</code></pre>

<p>I want to change the standard "3D" look of the standard asp.net checkbox to say solid 1px. If I try to apply the styling to the Border for example it does just that - draws the standard checkbox with a border around it - which is valid I guess.</p>
<p>Anyway, is there a way to change how the actual textbox is styled?</p>

<p>I'm using C++ and accessing a UNC path across the network. This path is slightly greater than MAX_PATH. So I cannot obtain a file handle.</p>
<p>But if I run the program on the computer in question, the path is not greater than MAX_PATH. So I can get a file handle. If I rename the file to have less characters (minus length of computer name) I can access the file. </p>
<p>Can this file be accessed across the network even know the computer name in the UNC path puts it over the MAX_PATH limit?</p>

<p>1.- Created the folder <strong>/etc/rc7.d/</strong>, which contains some symbolic links to <strong>/etc/init.d/</strong></p>
<p>2.- Created the file <strong>/etc/event.d/rc7</strong> This is its content:</p>
<pre><code># rc7 - runlevel 7 compatibility
#
# This task runs the old sysv-rc runlevel 7 ("multi-user") scripts. It
# is usually started by the telinit compatibility wrapper.
start on runlevel 7
stop on runlevel [!7]
console output
script
set $(runlevel --set 7 || true)
if [ "$1" != "unknown" ]; then
PREVLEVEL=$1
RUNLEVEL=$2
export PREVLEVEL RUNLEVEL
fi
exec /etc/init.d/rc 7
end script
</code></pre>
<p>I thought that would be enough, but <strong>telinit 7</strong> still throws this error: <em>telinit: illegal runlevel: 7</em></p>

<p>What's the difference between <code>file</code> and <code>open</code> in Python? When should I use which one? (Say I'm in 2.5)</p>

<p>I want to implement Generics in my Page Class like :</p>
<pre><code>Public Class MyClass(Of TheClass)
Inherits System.Web.UI.Page
</code></pre>
<p>But for this to work, I need to be able to instantiate the Class (with the correct Generic Class Type) and load the page, instead of a regular Response.Redirect. Is there a way to do this ?</p>

<p>I want to display data like the following:</p>
<pre><code> Title Subject Summary Date
</code></pre>
<p>So my <code>HTML</code> looks like:</p>
<pre><code><div class="title"></div>
<div class="subject"></div>
<div class="summary"></div>
<div class="date"></div>
</code></pre>
<p>The problem is, all the text doesn't appear on a single line. I tried adding <code>display="block"</code> but that doesn't seem to work.</p>
<p>What am I doing wrong here?</p>
<p><strong>Important:</strong> In this instance I dont want to use a <code>table</code> element but stick with <code>div</code> tags.</p>

<p>Im trying to put an html embed code for a flash video into the <code>rss feed</code>, which will then be parser by a parser <code>(magpie)</code> on my other site. How should I encode the embed code on one side, and then decode it on the other so I can insert clean html into the <code>DB</code> on the receiving server?</p>
