<p>What single aspect of agile development should we implement first to improve our development process, and why? </p>
<p>I'm in a situation that's requiring me to "tweak" my process, rather than re-engineer it, and "agile" seems to be the mantra of the day. If we can make only one change that will improve something--quality, time to market, documentation, transparency, <em>etc</em>., what will have the most visible, positive impact?</p>
<p>If we choose correctly, we'll be able to make a second choice. :-)</p>
<p><strong>Update:</strong> <em>What is your current SDLC?</em><br>
Environment: essentially "restartup." A <em>small</em> handful of developers; legacy products with 10^5-10^6 LOC and tens of thousands deployed worldwide; products are strongly interdependent; significant features added over the years, including many one-offs, w/o refactoring; tight schedules; superficial QA; no <em>post-mortems</em> or "process guru."</p>
<p>Typical process:</p>
<ol>
<li>Create design/spec. Review by all stakeholders.</li>
<li>Code one or more features/fixes.</li>
<li>Revise design/spec to account for surprises.</li>
<li>Test features, record defects.</li>
<li>Prioritize new and remaining tasks.</li>
<li>Revise design/spec/schedule.</li>
<li>Return to Step 2 as necessary.</li>
<li>Release for beta, record feedback.</li>
<li>Return to Step 2 as necessary. </li>
<li>Official release.</li>
</ol>
<p>Thanks for so many helpful suggestions and insights!</p>

<p>I have a bunch of ASP.NET web pages (that have a standard layout) that are product documentation. I want to create some sort of combination page that will pull all of the other page content in and concatenate them into one long page.</p>
<p>IFrames won't work because I don't know the size of each page. I could have the combination page do a ton of #includes, and that would work, but I don't want to have to keep the master update to date (we have a database of page names that can change over time).</p>
<p>Ultimately I'm after something that can get a list of pages, and for each one do the equivalent of a #include for that page into the current page.</p>
<p>I hope that makes sense. Any thoughts?</p>

<p>I have a table named Info of this schema:</p>
<pre><code>int objectId;
int time;
int x, y;
</code></pre>
<p>There is a lot of redundant data in the system - that is, <code>objectId</code> is not UNIQUE. For each <code>objectId</code> there can be multiple entries of <code>time, x, y</code>.</p>
<p>I want to retrieve a list of the latest position of each object. I started out with this query:</p>
<pre><code>SELECT * FROM Info GROUP BY objectId
</code></pre>
<p>That got me just the kind of list I was looking for. However I want also to get just the latest times for each Object, so I tried:</p>
<pre><code>SELECT * FROM Info GROUP BY objectId ORDER BY time DESC
</code></pre>
<p>This gave me a <code>time</code> descended list of Infos. However, <strong>I don't think it did what I want - that is return me the latest <code>time, x, y</code> for each object</strong>.</p>
<p>Can anyone imagine a query to do what I want?</p>
<p><strong>Update</strong> I have tried the top three solutions to see how they perform against each other on a dataset of about 50,000 Infos. Here are the results:</p>
<pre><code>-- NO INDEX: forever
-- INDEX: 7.67 s
SELECT a.*
FROM Info AS a
LEFT OUTER JOIN Info AS b ON (a.objectId = b.objectId AND a.time < b.time)
WHERE b.objectId IS NULL;
-- NO INDEX: 8.05 s
-- INDEX: 0.17 s
select a.objectId, a.time, a.x, a.y
from Info a,
(select objectId, max(time) time from Info group by objectId) b
where a.objectId = b.objectId and a.time = b.time;
-- NO INDEX: 8.30 s
-- INDEX: 0.18 s
SELECT A.time, A.objectId, B.x, B.y
FROM
(
SELECT max(time) as time, objectId
FROM Info
GROUP by objectId
) as A
INNER JOIN Info B
ON A.objectId = b.objectId AND A.time = b.time;
</code></pre>
<p>By a margin, it would seem <code>where</code> outperforms <code>inner join</code>.</p>

<p>I take care of critical app in my project. It does stuff related to parsing business msgs (legacy standard), processing them and then storing some results in a DB (another apps picks that up). After more then a year of my work (I've other apps to look after as well) the app is finally stable. I've introduced strict TDD policy and I have 20% unit test coverage (thank you Michael Feathers for your book!), most of it in critical parts. I have some white-box Fitness tests as well (whole business scenarios are covered there). I feel that I cannot further refactor this app and I'm safe to play hard with it. It's designed so badly, I want to rewrite it. App itself is around 20k of challenging legacy C/C++ code. There were other dependencies but I manged to decouple most of them.</p>
<hr>
<p>All I have is Sun C++ compiler, cppunitlite, STLPort and Boost. Please do not suggest other technologies (no XML, Java etc) as this is not the option in my organization.
I'd like to do it with modern C++ (perhaps play with metaprogramming...), TDD from start to the end.</p>
<p>There are about 30 types of msgs I need to parse. Each of them is composed of 3-10 lines, most of them are pretty similar.
This is root of all evil -> lots of code duplication.
Each msgs has a class describing how it should be parsed. Take a look at the main inheritance tree:</p>
<pre><code> MSG_A MSG_B
/ \ / \
MSG_A_NEW MSG_A_CNL MSG_B_NEW MSG_B_CNL
</code></pre>
<p>Both trees goes much deeper. There are very small differences between MSG_A_NEW and MSG_B_NEW. It should be handled by single class that could be injected with some small customization.</p>
<p>My initial plan it to have one generic msg class that will be customized. Some entity (builder... ?) will take a look at the msgs and initialize proper object that will be able to parse the msg. Another entity will be able to discover what line is it and this info will be used by builder. I'm planning to write several parsers that are responsible for parsing just one specific line. This will allow me to reuse it in parsing different msgs.</p>
<p>There are several challenges that I struggle to solve in an elegant and extensible way.
Each type of msg:</p>
<p>has min and max number if lines
- has some must-have lines
- has some optional lines
- certain lines must be at certain places (i.e. date cannot be before msg type), order matters</p>
<p>I need to be able to validate format of the msgs.</p>
<hr>
<p>I'm not sure if I explained the design challenge here good enough. My design experience is very limited. I've been bug-fixing for a while now and finally I will have a change to do some fun codding :)</p>
<p>What high-level advice do you have for that? Which design patterns can you identify in this description? Main design constraint is maintainability and extensibility with performance at the bottom (we have other bottlenecks anyway...).</p>

<p>With DWR it is possible to group together several service calls into one single HTTP request :<br>
<a href="http://directwebremoting.org/dwr/browser/engine/batch" rel="noreferrer">dwr batch feature</a><br><br>
This feature is very useful to reduce the latency of an ajax application.
Is there a way to do something similar with GWT / GWT-RPC ?<br>
Thanks for your help</p>

<p>I have a PHP class that creates a PNG image on the fly and sends it to browser. PHP manual says that I need to make sure that <em>imagedestroy</em> function is called at end to release the memory. Now, if I weren't using a class, I would have some code like this:</p>
<pre><code>function shutdown_func()
{
global $img;
if ($img)
imagedestroy($img);
}
register_shutdown_function("shutdown_func");
</code></pre>
<p>However, I believe that appropriate place for my class would be to place a call to <em>imagedestroy</em> in class' destructor.</p>
<p>I failed to find out if destructors get called the same way shutdown functions does? For example, if execution stops when user presses the STOP button in browser.</p>
<p>Note: whatever you write in your answer, please point to some article or manual page (URL) that supports it.</p>

<p>That's basically the question, is there a "right" way to implement <code>operator<<</code> ?
Reading <a href="http://bytes.com/forum/thread170304.html" rel="noreferrer">this</a> I can see that something like:</p>
<pre><code>friend bool operator<<(obj const& lhs, obj const& rhs);
</code></pre>
<p>is preferred to something like </p>
<pre><code>ostream& operator<<(obj const& rhs);
</code></pre>
<p>But I can't quite see why should I use one or the other.</p>
<p>My personal case is:</p>
<pre><code>friend ostream & operator<<(ostream &os, const Paragraph& p) {
return os << p.to_str();
}
</code></pre>
<p>But I could probably do:</p>
<pre><code>ostream & operator<<(ostream &os) {
return os << paragraph;
}
</code></pre>
<p>What rationale should I base this decision on?</p>
<p><em>Note</em>:</p>
<pre><code> Paragraph::to_str = (return paragraph)
</code></pre>
<p>where paragraph's a string.</p>

<p>I'm trying to extract an uploaded zip file and store its contents in the database, one entry per file. The rubyzip library has nearly no useful documentation.</p>
<p>There is an assets table that has key :string (file name) and data :binary (file contents).</p>
<p>I'm using the rubyzip library, and have made it as far as this:</p>
<pre><code>Zip::ZipFile.open(@file_data.local_path) do |zipfile|
zipfile.each do |entry|
next if entry.name =~ /__MACOSX/ or entry.name =~ /\.DS_Store/ or !entry.file?
asset = self.assets.build
asset.key = entry.name
asset.data = ?? # what goes here?
end
end
</code></pre>
<p>How can I set the data from a ZipEntry? Do I have to use a temp file?</p>

<p>Are there any good books for a relatively new but not totally new *nix user to get a bit more in depth knowledge (so no "Linux for dummies")? For the most part, I'm not looking for something to read through from start to finish. Rather, I'd rather have something that I can pick up and read in chunks when I need to know how to do something or whenever I have one of those "how do I do that again?" moments. Some areas that I'd like to see are:</p>
<ul>
<li>command line administration</li>
<li>bash scripting</li>
<li>programming (although I'd like something that isn't just relevant for C programmers)</li>
</ul>
<p>I'd like this to be as platform-independent as possible (meaning it has info that's relevant for any linux distro as well as BSD, Solaris, OS X, etc), but the unix systems that I use the most are OS X and Debian/Ubuntu. So if I would benefit the most from having a more platform-dependent book, those are the platforms to target.</p>
<p>If I can get all this in one book, great, but I'd rather have a bit more in-depth material than coverage of <strong>everything</strong>. So if there are any books that cover just one of these areas, post it. Hell, post it even if it's not relevant to any of those areas and you think it's something that a person in my position should know about.</p>

<p>I currently work at a company that has a lot of custom applications that are made internally. There are not currently standards for a lot of things. I would like to implement a way to record/track errors that happen in this programs (most are asp.net).</p>
<p>I am currently thinking of handling this in the Global.asax in the Application Error method. First trying to save the information to an Error Log/Tracking database, and if that fails, try sending an e-mail.</p>
<p>What type of information is the most useful to get from the error message and other application variables (page, username etc).</p>
<p>I am currently thinking of using two tables, one to get the general error and application information, and a second that holds the exception information. This will be a one to many relationship to hand the inner Exceptions that can come from one Application level exception.</p>
<p>I am sure that I am missing a lot of details and would like to hear your strategy for handling this issue.</p>

<p>Any python libs for parsing Bind zone files?
Basically something that will aid in adding/removing zones and records.
This needs to work even if someone modifies the zone file by hand so overwriting the zone files every time is not a solution. </p>

<p>this is a question that when programming I always wonder: What to use when we are writing code: </p>
<pre><code>var myFiles = Directory.GetFiles(fullPath);
</code></pre>
<p>or</p>
<pre><code>string[] myFiles = Directory.GetFiles(fullPath);
</code></pre>
<p><strong><em>var</em></strong> is new and is a <em>Implicitly Typed Local Variables</em>, so we can only use locally and it has rules like can't be null, etc., but I wonder if we get any advantage of using it "normally". </p>
<p>The "normally" part says, not in <strong>Anonymous Types</strong>, <strong>Object and Collection Initializers</strong> and <strong>Query Expressions</strong> where that was the intent to use the var anonymous object, so what I mean is... just like the example above.</p>
<p>what are your thoughts?</p>

<p>I have a request for some contract work from an organization that uses <a href="http://www.neopoleon.com/home/blogs/neo/archive/2003/09/29/5458.aspx" rel="nofollow noreferrer">Excel as a database</a> and wants to do some work on the Excel data via a real database. (Yeah, I know, never mind...)</p>
<p>The client has an Excel sheet that they use internally to keep track of some government programmes. The data from this Excel sheet used to be manually imported into a SQL database via CSV as intermediate format and made available via a tiny web app. Changes in either the spreadsheet or the db were done manually (by different people) and had to be kept in sync manually.</p>
<p>The spec for new functionality includes:</p>
<ul>
<li>upload the Excel file into the web app</li>
<li>make minor changes via the web app (this bit is, of course, a no-brainer)</li>
<li>occasionally export the data back into Excel</li>
</ul>
<p>The spreadsheet (actually, it's a couple of them in a workbook) implements some guidelines necessary to interact with other institutions and therefore has to remain the same structurally before and after import. It contains a lot of formatting, hidden columns and sort buttons as well as a lot of data links between the cells in the different sheets.</p>
<p>I don't want to have to reproduce the spreadsheet from scratch to deliver the export, nor do I want to manually extract the proper columns into CSV before making the import. I'm rather looking for a way to load the Excel, "query" certain fields, write them to the DB and later load the data back from the DB and manipulate only the contents of the proper cells.</p>
<p>Is there a way to programatically interface with an existing spreadsheet and only read or change the bits that you need?</p>

<p>I have some code that generates image of a pie chart. It's a general purpose class, so any number of slices can be given as input. Now I have problem picking good colors for the slices. Is there some algorithm that is good at that?</p>
<p>Colors need to follow some rules:</p>
<ul>
<li>they need to look nice</li>
<li>adjacent colors should not be similar (blue next to green is a no-go)</li>
<li>pie background color is white, so white is out of option</li>
</ul>
<p>Some algorithm manipulating with RGB values would be a preferred solution.</p>

<p>Based on this question <a href="https://stackoverflow.com/questions/19746/views-in-seperate-assemblies-in-aspnet-mvc">here</a> and using code found <a href="http://www.codeproject.com/KB/aspnet/ASP2UserControlLibrary.aspx" rel="nofollow noreferrer">here</a> I'm trying to load views that are embedded resources in a separate DLL project, and the original question's author says he has had success doing this - but I can't get it to work as it seems the MVC view engine is intercepting the request and still looking at the file system for the view. Exception:</p>
<pre><code>Server Error in '/' Application.
The view 'Index' or its master could not be found. The following locations were searched:
~/Views/admin/Index.aspx
~/Views/admin/Index.ascx
~/Views/Shared/Index.aspx
~/Views/Shared/Index.ascx
~/App/Views/admin/Index.aspx
~/App/Views/admin/Index.ascx
~/App/Views/Shared/Index.aspx
~/App/Views/Shared/Index.ascx
</code></pre>
<p>I am using a <code>CustomViewEngine</code>, like Rob Connery's /App structure one as follows:</p>
<pre><code>public class CustomViewEngine : WebFormViewEngine
{
public CustomViewEngine()
{
MasterLocationFormats = new[] {
"~/App/Views/{1}/{0}.master",
"~/App/Views/Shared/{0}.master"
};
ViewLocationFormats = new[] {
"~/App/Views/{1}/{0}.aspx",
"~/App/Views/{1}/{0}.ascx",
"~/App/Views/Shared/{0}.aspx",
"~/App/Views/Shared/{0}.ascx"
};
PartialViewLocationFormats = ViewLocationFormats;
}
}
</code></pre>
<p>Here are my routes:</p>
<pre><code> routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute("Home", "", new {controller = "Page", action = "Index", id = "Default"});
routes.MapRoute("Default", "Page/{id}", new { controller = "Page", action = "Index", id = "" });
routes.MapRoute("Plugins", "plugin/{controller}/{action}", new { controller = "", action = "Index", id = "" });
routes.MapRoute("Error", "{*url}", new { controller = "Error", action = "ResourceNotFound404" });
</code></pre>
<p>In my <a href="http://www.codeproject.com/KB/aspnet/ASP2UserControlLibrary.aspx" rel="nofollow noreferrer"><code>AssemblyResourceProvider</code></a> I'm checking to see if the path starts <code>~/plugin/</code> and then using the dll filename convention <code>plugin.{controller}.dll</code></p>
<p>Any suggestions?</p>
<p><strong>UPDATE:</strong> By the time the routed request for say <code>http://localhost/plugin/admin</code> is getting to the VirtualFileProvider it doesn't have any View attached at the end. So in the <code>VirtualFileProvider</code>'s Open method the virtual path of <code>~/plugin/admin</code> is being passed in when it should be <code>~/plugin/admin/Index.aspx</code> as defined in my route above. Have I messed up my routes or am I right to be expecting this to happen?</p>

<p>I'm creating a CSS editor and am trying to create a regular expression that can get data from a CSS document. This regex works if I have one property but I can't get it to work for all properties. I'm using preg/perl syntax in PHP.</p>
<h3>Regex</h3>
<pre><code>(?<selector>[A-Za-z]+[\s]*)[\s]*{[\s]*((?<properties>[A-Za-z0-9-_]+)[\s]*:[\s]*(?<values>[A-Za-z0-9#, ]+);[\s]*)*[\s]*}
</code></pre>
<h3>Test case</h3>
<pre><code>body { background: #f00; font: 12px Arial; }
</code></pre>
<h3>Expected Outcome</h3>
<pre><code>Array(
[0] => Array(
[0] => body { background: #f00; font: 12px Arial; }
[selector] => Array(
[0] => body
)
[1] => Array(
[0] => body
)
[2] => font: 12px Arial;
[properties] => Array(
[0] => font
)
[3] => Array(
[0] => font
)
[values] => Array(
[0] => 12px Arial
[1] => background: #f00
)
[4] => Array(
[0] => 12px Arial
[1] => background: #f00
)
)
)
</code></pre>
<h3>Real Outcome</h3>
<pre><code>Array(
[0] => Array
(
[0] => body { background: #f00; font: 12px Arial; }
[selector] => body
[1] => body
[2] => font: 12px Arial;
[properties] => font
[3] => font
[values] => 12px Arial
[4] => 12px Arial
)
)
</code></pre>
<p>Thanks in advance for any help - this has been confusing me all afternoon!</p>

<p><strong>EDIT:</strong> I think I only allowed Sql Server Authentication. Login with integrated security also does not work.</p>

<p>Here's my problem: I have a virtual method defined in a .h file that I want to call in a class that inherits from the base class. Sadly though, the method in the derived class doesn't get called. Is there a better way to implement what I'm trying to do?</p>
<pre><code>#ifndef ofxBASE_SND_OBJ
#define ofxBASE_SND_OBJ
#include "ofConstants.h"
class ofxBaseSndObj {
public:
virtual string getType(){}
string key;
};
#endif
</code></pre>
<p>Here's my buzz class</p>
<pre><code>#ifndef OFXSO_BUZZ
#define OFXSO_BUZZ
#include "ofxBaseSndObj.h"
class ofxSOBuzz : public ofxBaseSndObj
{
public:
string getType();
};
#endif
</code></pre>
<p>ofxSOBuzz.cpp</p>
<pre><code>string ofxSOBuzz::getType()
{
string s = string("ofxSOBuzz");
printf(" ********* returning string type %s", s.c_str()); // doesn't get called!
return s;
}
</code></pre>
<p>Then in another class I try to call it this way:</p>
<pre><code>string ofxSndObj::createFilter(ofxBaseSndObj obj)
{
string str = obj.getType();
if(str.compare("ofxSOBuzz") == 0)
{
printf(" all is well ");
}
}
</code></pre>
<p>In the method above I need to be able to pass in one of many kinds of objects that all extend the ofxBaseSndObj object. Any suggestsions or pointers would be greatly appreciated. Thanks!</p>

<p>Does anyone know what will be in .NET 4.0?</p>
<p>I found <a href="https://mef.svn.codeplex.com/svn/src/ComponentModel/System/Tuple.cs" rel="nofollow noreferrer">tuples on codeplex</a>:</p>
<pre><code>....

<p>I'm trying to compile code from F# to use in Silverlight. I compile with:</p>
<p>--noframework --cliroot "C:\program Files\Microsoft Silverlight\2.0.31005.0" --standalone</p>
<p>This generates a standalone assembly that references the SL framework. But when I try to add a reference to the generated assembly, I get this error:</p>
<blockquote>
<p>You can only add project references to
other Silverlight projects in the
solution.</p>
</blockquote>
<p>What is the VS plugin doing to determine that this isn't a Silverlight assembly? Here's the manifest:</p>
<pre><code>// Metadata version: v2.0.50727
.assembly extern mscorlib
{
.publickeytoken = (7C EC 85 D7 BE A7 79 8E ) // |.....y.
.ver 2:0:5:0
}
.assembly FSSLLibrary1
{
// --- The following custom attribute is added automatically, do not uncomment -------
// .custom instance void [mscorlib]System.Diagnostics.DebuggableAttribute::.ctor(valuetype [mscorlib]System.Diagnostics.DebuggableAttribute/DebuggingModes) = ( 01 00 01 01 00 00 00 00 )
.hash algorithm 0x00008004
.ver 0:0:0:0
}
.module 'F#-Module-FSSLLibrary1'
// MVID: {49038883-5D18-7281-A745-038383880349}
.imagebase 0x00400000
.file alignment 0x00000200
.stackreserve 0x00100000
.subsystem 0x0003 // WINDOWS_CUI
.corflags 0x00000001 // ILONLY
// Image base: 0x04120000
</code></pre>
<p>I don't understand what it's finding that it doesn't like; it's pure verifiable IL. I compared to a SL "class library" assembly, and it looks the same. The only difference was some attributes, but I deleted those and VS still let me reference the DLL. I even added unverifiable IL to the "SL library" DLL and it still loaded.</p>
<p>Any suggestions?</p>
<p><em>Update:</em> I've done some poking around, and it doesn't seem to be the manifest that matters. It doesn't like something in the IL from the FSharp libraries. They are peverifiable, but something in there is triggering the rejection. </p>

<p>A string will be made up of certain symbols (ax,bx,dx,c,acc for example) and numbers.</p>
<p>ex:
ax 5 5
dx 3 acc
c ax bx</p>
<p>I want to replace one or all of the symbols (randomly) with another symbol of the same set. ie, replace one of {ax,bx,dx,c,acc} with one of {ax,bx,dx,c,acc}.</p>
<p>replacement example:
acc 5 5
dx 3 acc
c ax bx
or
c 5 5
dx 3 acc
c ax ax</p>
<p>Is there a way to do this with regexes? In Java? If so, which methods should I use?</p>

<p>I have several strings in the rough form:</p>
<pre><code>[some text] [some number] [some more text]
</code></pre>
<p>I want to extract the text in [some number] using the Java Regex classes.</p>
<p>I know roughly what regular expression I want to use (though all suggestions are welcome). What I'm really interested in are the Java calls to take the regex string and use it on the source data to produce the value of [some number].</p>
<p>EDIT: I should add that I'm only interested in a single [some number] (basically, the first instance). The source strings are short and I'm not going to be looking for multiple occurrences of [some number].</p>

<p>I have a report that renders data returned from a stored procedure. Using profiler I can catch the call to the stored procedure from the reporting services.</p>
<p>The report fails stating the report timed out yet I can execute the stored procedure from SSMS and it returns the data back in five to six seconds.</p>
<p>Note, in the example test run only two rows are returned to the report for rendering though within the stored procedure it may have been working over thousands or even millions of records in order to collate the result passed back to reporting services.</p>
<p>I know the stored procedure could be optimised more but I do not understand why SSRS would be timing out when the execution only seems to take a few seconds to execute from SSMS.</p>
<p>Also another issue has surfaced. If I recreate the stored procedure, the report starts to render perfectly fine again. That is fine except after a short period of time, the report starts timing out again.</p>
<p>The return of the time out seems to be related to new data being added into the main table the report is running against. In the example I was testing, just one hundred new records being inserted was enough to screw up the report.</p>
<p>I imagine more correctly its not the report that is the root cause. It is the stored procedure that is causing the time out when executed from SSRS.</p>
<p>Once it is timeing out again, I best fix I have so far is to recreate the stored procedure. This doesn't seem to be an ideal solution.</p>
<p>The problem also only seems to be occuring on our production environment. Our test and development platforms do not seem to be exhibiting the same problem. Though dev and test do not have the same volume of records as production.</p>

<p>It's possible to write <a href="http://en.wikipedia.org/wiki/Markdown" rel="noreferrer">Markdown</a> content with invalid syntax. Invalid means that the <a href="http://www.deveiate.org/projects/BlueCloth" rel="noreferrer">BlueCloth</a> library fails to parse the content and throws an exception. The <code>markdown</code> helper in Rails doesn't catch any BlueCloth exceptions and because of that the complete page fails to render (500 Server Error page is rendered instead).</p>
<p>In my case, users are allowed to write Markdown content and save it to the database. If someone used invalid syntax, all successive rendering attempts of that content fail (Status Code 500 - Internal Server Error).</p>
<p>How do you get around this issue? Is it possible to validate the Markdown syntax at the Model-level before saving to the database?</p>

<p>What is the most concise and efficient way to find out if a JavaScript array contains a value?</p>
<p>This is the only way I know to do it:</p>
<pre><code>function contains(a, obj) {
for (var i = 0; i < a.length; i++) {
if (a[i] === obj) {
return true;
}
}
return false;
}
</code></pre>
<p>Is there a better and more concise way to accomplish this?</p>
<p>This is very closely related to Stack Overflow question <em><a href="https://stackoverflow.com/questions/143847/best-way-to-find-an-item-in-a-javascript-array">Best way to find an item in a JavaScript Array?</a></em> which addresses finding objects in an array using <code>indexOf</code>.</p>

<p>I have a legacy DLL written in C that contains a function that returns a string, and I need to access this function from Delphi. The only info I have about the DLL is the VB declare for accessing the function:</p>
<p>Public Declare Function DecryptStr Lib "strlib" (Str As String) As String </p>
<p>I've tried the following without success:</p>
<p>Declaration:</p>
<pre><code>function DecryptStr(s: PChar): PChar; cdecl; external 'strlib.dll';
</code></pre>
<p>Usage:</p>
<pre><code>var
p1, p2 : pchar;
begin
GetMem( p1, 255 );
StrPCopy( p2, 'some string to decrypt' );
p1 := DecryptStr( p2 );
end;
</code></pre>
<p>This consistently crashes the DLL with an Access Violation. I'm at a loss.</p>
<p>Any suggestions ?</p>

<p>Working on a project where a sequential set of methods must be run every <code>x</code> seconds. Right now I have the methods contained within another "parent method", and just sequentially call them right after another.</p>
<pre><code>class DoTheseThings()
{
DoThis();
NowDoThat();
NowDoThis();
MoreWork();
AndImSpent();
}
</code></pre>
<p>Each method must run successfully without throwing an exception before the next step can be done. So now I wrapped each of those methods with a <code>while</code> and <code>try..catch</code>, then in the <code>catch</code> execute that method again.</p>
<pre><code>while( !hadError )
{
try
{
DoThis();
}
catch(Exception doThisException )
{
hadError = true;
}
}
</code></pre>
<p>This seems smelly and not very dry. Is there a better way to do this so I'm not wrapping any new functionality in the same methods. Isn't some kind of Delegate collection the proper way to implement this? </p>
<p>Is there a more "proper" solution?</p>

<p>I'm doing some research work into content aggregators, and I'm curious how some of the current craigslist aggregators get data into their mashups.</p>
<p>For example, www.housingmaps.com and the now closed www.chicagocrime.org</p>
<p>If there is a URL that can be used for reference, that would be perfect!</p>

<p>I have a <code>JPanel</code> extension that I've written and would like to be able to use it in the NetBeans designer. The component is simply adds some custom painting and continues to function as a container to be customised on each use. </p>
<p>I have properties to expose in addition to the standard <code>JPanel</code> ones and have a custom <code>paintComponent()</code> method that I'd like to be able to see in use when building up GUIs. Ideally I'd like to associate an icon with the component as well so that its easily recognisable for my colleagues to work with.</p>
<p>What's the best way of achieving this?</p>

<p>I was re-reading Effective Java (2nd edition) item 18, <a href="http://my.safaribooksonline.com/9780137150021/ch04lev1sec6" rel="nofollow noreferrer">prefer interfaces to abstract classes</a>. In that item Josh Bloch provides an example of a skeletal implementation of the <code>Map.Entry<K,V></code> interface:</p>
<pre><code>// Skeletal Implementation
public abstract class AbstractMapEntry<K,V>
implements Map.Entry<K,V> {
// Primitive operations
public abstract K getKey();
public abstract V getValue();
// ... remainder omitted
}
</code></pre>
<p>Two questions stem from this example:</p>
<ol>
<li>Why are getKey and getValue explicitly declared here as abstract methods? They are part of the <a href="http://java.sun.com/j2se/1.5.0/docs/api/java/util/Map.Entry.html" rel="nofollow noreferrer">Map.Entry</a> interface, so I don't see a reason for the redundant declaration in the abstract class.</li>
<li><p>Why use the idiom of leaving these primitives methods, as Mr. Bloch refers to them, as abstract? Why not just do this:</p>
<p>// Skeletal Implementation
public abstract class AbstractMapEntry
implements Map.Entry {
private K key;
private V value;</p>
<pre><code> // Primitive operations
public K getKey() {return key;}
public V getValue() {return value;}
// ... remainder omitted
</code></pre>
<p>}</p></li>
</ol>
<p>The benefits of this are that each subclass doesn't have to define its own set of fields, and can still access the key and value by their accessors. If a subclass truly needs to define its own behavior for the accessors, it can implement the Map.Entry interface directly. The other downside is that in the equals method provided by the skeletal implementation, the abstract accessors are called:</p>
<pre><code>// Implements the general contract of Map.Entry.equals
@Override public boolean equals(Object o) {
if (o == this)
return true;
if (! (o instanceof Map.Entry))
return false;
Map.Entry<?,?> arg = (Map.Entry) o;
return equals(getKey(), arg.getKey()) &&
equals(getValue(), arg.getValue());
}
</code></pre>
<p>Bloch warns against calling overridable methods (item 17) from classes designed for inheritance as it leaves the superclass vulnerable to changes made by subclasses.
Maybe this is a matter of opinion, but I was hoping to determine whether there's more to the story, as Bloch doesn't really elaborate on this in the book.</p>

<p>I have a radio button on my Windows Form. How can I determine if the CheckChanged event occurred due to a user clicking or selecting the radio button vs programatically setting the event with </p>
<pre><code>this.radioButtonAdd.Checked = true;
</code></pre>
<p>I would like some code to take a different action depending on if the user clicked the button or I raised the event myself.</p>
<p>Or maybe the better question is how do I handle the event when a user clicks vs when the state is changed in my code.</p>

<p>Is there a way to accept input from more than one mouse separately? I'm interested in making a multi-user application and I thought it would be great if I could have 2 or more users holding wireless mice each interacting with the app individually with a separate mouse arrow.</p>
<p>Is this something I should try to farm out to some other application/driver/os_magic? or is there a library I can use to accomplish this? Language isn't a <em>HUGE</em> deal, but C, C++, and Python are preferrable.</p>
<p>Thanks :)</p>
<p>edit:</p>
<p>Found this multi-pointer toolkit for linux (it's actually a multi-pointer x server):

<p>I normally use the following idiom to check if a String can be converted to an integer.</p>
<pre><code>public boolean isInteger( String input ) {
try {
Integer.parseInt( input );
return true;
}
catch( Exception e ) {
return false;
}
}
</code></pre>
<p>Is it just me, or does this seem a bit hackish? What's a better way?</p>
<hr>
<p>See my answer (with benchmarks, based on the <a href="https://stackoverflow.com/a/237321/1288">earlier answer</a> by <a href="https://stackoverflow.com/users/28278/codingwithspike">CodingWithSpike</a>) to see why I've reversed my position and accepted <a href="https://stackoverflow.com/a/237204/1288">Jonas Klemming's answer</a> to this problem. I think this original code will be used by most people because it's quicker to implement, and more maintainable, but it's orders of magnitude slower when non-integer data is provided.</p>

<p>I'm experimenting with the NavBar sample project for iPhone. When I tap on one of the rows in the table in the default view a new view slides in (so far so good). I want to remove the UINavigationBar bar at the top of the new view that slides in. How can I do this? </p>
<p>EDIT: I meant "UINavigationBar". Thanks to everyone who responded!</p>

<p>I'm trying to perform a simple LINQ query on the Columns property of a DataTable:</p>
<pre><code>from c in myDataTable.Columns.AsQueryable()
select c.ColumnName
</code></pre>
<p>However, what I get is this:</p>
<blockquote>
<p>Could not find an implementation of the query pattern for source type 'System.Linq.IQueryable'. 'Select' not found. Consider explicitly specifying the type of the range variable 'c'.</p>
</blockquote>
<p>How can I get the DataColumnCollection to play nice with LINQ?</p>

<p>I am working on an application that uses several large canvas controls (several thousand pixels across), layered on top of each other. The canvas controls themselves are completely invisible, but each contains a number of controls, mainly images.</p>
<p>My question is, is there a recommended maximum size for a canvas, or is it purely a memory issue? And also, are we better off setting the Canvas size to (0, 0) and making use of the fact that we can happily render controls outside of the bounds of the canvas?</p>
<p>Thanks,</p>
<p>G</p>

<p>I'm looking for an algorithm that places tick marks on an axis, given a range to display, a width to display it in, and a function to measure a string width for a tick mark.</p>
<p>For example, given that I need to display between 1e-6 and 5e-6 and a width to display in pixels, the algorithm would determine that I should put tickmarks (for example) at 1e-6, 2e-6, 3e-6, 4e-6, and 5e-6. Given a smaller width, it might decide that the optimal placement is only at the even positions, i.e. 2e-6 and 4e-6 (since putting more tickmarks would cause them to overlap).</p>
<p>A smart algorithm would give preference to tickmarks at multiples of 10, 5, and 2. Also, a smart algorithm would be symmetric around zero.</p>

<p>This code:</p>
<pre><code>public class WidgetPlatform
{
public Widget LeftmostWidget { get; set; }
public Widget RightmostWidget { get; set; }
public String GetWidgetNames()
{
return LeftmostWidget.Name + " " + RightmostWidget.Name;
}
}
</code></pre>
<p>doesn't contain any repetition worth worrying about, but it isn't particularly robust. Because the Widgets aren't null-checked, we're leaving an opening for a bug. We could do a null check, but that feels like work. Here's what I really want:</p>
<pre><code>public class WidgetPlatform
{
[Required]
public Widget LeftmostWidget { get; set; }
[Required]
public Widget RightmostWidget { get; set; }
public String GetWidgetNames()
{
return LeftmostWidget.Name + " " + RightmostWidget.Name;
}
}
</code></pre>
<p>Ideally, it would cause a compile error (the best sort of error) if the object was instantiated without setting the Widgets, but that seems like a tall order. Is there a way to make this syntax work that at least throws an error on instantiation? There's a (relatively) obvious way to do it with reflection if all of the null-checked objects inherit from the same type, but without multiple inheritance that will get ugly pretty fast.</p>

<p>In my django application I am using a template to construct email body, one of the parameters is url, note there are two parametes separated by ampersand in the url.</p>
<pre><code>t = loader.get_template("sometemplate")
c = Context({
'foo': 'bar',
'url': 'http://127.0.0.1/test?a=1&b=2',
})
print t.render(c)
</code></pre>
<p>After rendering it produces: <code>http://127.0.0.1/test?a=1&amp;amp;b=2</code></p>
<p>Note the ampersand is HTML encoded as "&amp;". One way around the problem is to pass each parameter separately to my template and construct the url in the template, however I'd like to avoid doing that.</p>
<p>Is there a way to disable HTML encoding of context parameters or at the very least avoid encoding of ampersands?</p>

<p>The <a href="http://docs.jquery.com/Events/bind#typedatafn" rel="noreferrer">jQuery documentation</a> says the library has built-in support for the following events: blur, focus, load, resize, scroll, unload, click, dblclick, mousedown, mouseup, mousemove, mouseover, mouseout, mouseenter, mouseleave, change, select, submit, keydown, keypress, keyup, and error.</p>
<p>I need to handle cut, copy, and paste events. How best to do that? FWIW, I only need to worry about WebKit (lucky me!).</p>
<p>UPDATE: I'm working on a "widget" in a Dashboard-like environment. It uses WebKit, so it only really matters (for my purposes) whether these events are supported there, which it looks like they are.</p>

<p>I'm constructing a method to take in an ArrayList(presumably full of objects) and then list all the fields(and their values) for each object in the ArrayList.</p>
<p>Currently my code is as follows:</p>
<pre><code>public static void ListArrayListMembers(ArrayList list)
{
foreach (Object obj in list)
{
Type type = obj.GetType();
string field = type.GetFields().ToString();
Console.WriteLine(field);
}
}
</code></pre>
<p>Of course, I understand the immediate issue with this code: if it worked it'd only print one field per object in the ArrayList. I'll fix this later - right now I'm just curious how to get all of the public fields associated with an object.</p>

<p>At work, we have one of those nasty communal urinals. There is no flush handle. Rather, it has a motion sensor that sometimes triggers when you stand in front of it and sometimes doesn't. When it triggers, a tank fills, which when full is used to flush the urinal.</p>
<p>In my many trips before this nastraption, I have pondered both what the algorithm is the box uses to determine when to turn on and what would be the optimal algorithm, in terms of conserving water while still maintaining a relatively pleasant urinal experience.</p>
<p>I'll share my answer once folks have had a chance to share their ideas.</p>

<p>At my workplace, we tend to use <strong>iostream</strong>, <strong>string</strong>, <strong>vector</strong>, <strong>map</strong>, and the odd <strong>algorithm</strong> or two. We haven't actually found many situations where template techniques were a best solution to a problem.</p>
<p>What I am looking for here are ideas, and optionally sample code that shows how you used a template technique to create a new solution to a problem that you encountered in real life.</p>
<p>As a bribe, expect an up vote for your answer.</p>

<p>I'm looking for a way to configure the color used for line numbering (as in: <code>:set nu</code>) in Vim. The default on most platforms seems to be yellow (which is also used for some highlighted tokens). I would <em>like</em> to color the line numbers a dim gray; somewhere in the vicinity of <code>#555</code>. I'm not picky though, any subdued color would be acceptable.</p>

<p>I'm currently displaying a UIViewController like this:</p>
<pre><code>[[self navigationController] presentModalViewController:modalViewController animated:YES];
</code></pre>
<p>and hiding it like this:</p>
<pre><code>[self.navigationController dismissModalViewControllerAnimated:YES];
</code></pre>
<p>The animation is "slide up from the bottom"... then slide back down. How can I change the animation style? Can I made it fade in/out?</p>
<p>Cheers!</p>

<p>You'd think it would be easy, but keep reading. I can change many of the styles associated with a resizable JQuery Dialog, but not the handles. The code below isolates the problem. Why does the handle disappear entirely? There must be some logic I'm interfering with in ui.resizable.js, but I don't see it.</p>
<pre><code><script type="text/javascript" language="JavaScript" src="jquery126.js"></script>
<script type="text/javascript" language="JavaScript" src="ui/ui.core.js"></script>
<script type="text/javascript" language="JavaScript" src="ui/ui.dialog.js"></script>
<script type="text/javascript" language="JavaScript" src="ui/ui.resizable.js"></script>
<script type="text/javascript" language="JavaScript" src="ui/ui.draggable.js"></script>
<script>
$(document).ready(foo);
function foo() {
$("#dlg").dialog()
}
</script>
<style type="text/css">
.ui-resizable-n {
background: green;
}
</style>
<div id=dlg title="my title">this is<br>my text</div>

<p>In particular, would it be possible to have <strong>code similar to this c++ code executed at compile time in c#</strong>?</p>
<pre><code>template <int N>
struct Factorial
{
enum { value = N * Factorial<N - 1>::value };
};
template <>
struct Factorial<0>
{
enum { value = 1 };

// Factorial<4>::value == 24
// Factorial<0>::value == 1
void foo()

<p>The UPSERT operation either updates or inserts a row in a table, depending if the table already has a row that matches the data:</p>
<pre><code>if table t has a row exists that has key X:
update t set mystuff... where mykey=X
else
insert into t mystuff...
</code></pre>
<p>Since Oracle doesn't have a specific UPSERT statement, what's the best way to do this?</p>

<p>I am trying to call a setTimeout from within a setInterval callback:</p>
<pre><code>function callback()
{
//assign myVar
var myVar = document.getElementById("givenID");
//...
//now wait 2 secs then call some code that uses myVAr
setTimeout("myVar.innerHTML = 'TEST'", 2000);
}
setInterval("callback();", 10000);
</code></pre>
<p>setInterval works as expected but setTimeout call is failing. I guess the problem is related to the fact that I am referencing a variable (myVar) that's not in scope.</p>
<p>What's the best way to solve this?</p>

<p>When I connect to a MySQL database using PDO, the way I need to connect is:</p>
<pre><code>$pdoConnection = new PDO("mysql:host=hostname;dbname=databasename",user,password);
</code></pre>
<p>But, for PostgreSQL, the DSN is more standard (IMO):</p>
<pre><code>$pdoConnection = new PDO("pgsql:host=hostname;dbname=databasename;user=username;password=thepassword");
</code></pre>
<p>Is there any reason why MySQL cannot use a single string? Or is this just because of the versions I am using (PHP 5.2, MySQL 5.0, PostgreSQL 8.1)?</p>

<p>In some code I've inherited, I see frequent use of <code>size_t</code> with the <code>std</code> namespace qualifier. For example:</p>
<pre><code>std::size_t n = sizeof( long );

<p>It compiles and runs fine, of course. But it seems like bad practice to me (perhaps carried over from C?).</p>
<p>Isn't it true that <code>size_t</code> is built into C++ and therefore in the global namespace? Is a header file include needed to use <code>size_t</code> in C++?</p>
<p>Another way to ask this question is, would the following program (with <em>no</em> includes) be expected to <em>compile</em> on all C++ compilers?</p>
<pre><code>size_t foo()
{
return sizeof( long );
}
</code></pre>

<p>Is there a better way to do this?</p>
<pre><code>string[] s = {"zero", "one", "two", "three", "four", "five"};
var x =
s
.Select((a,i) => new {Value = a, Index = i})
.Where(b => b.Value.StartsWith("t"))

<p>i.e. I'm looking for a more efficient or more elegant way to get the positions of the items matching the criteria.</p>

<p>Is possible to insert a line break where the cursor is in Vim without entering into insert mode? Here's an example (<code>[x]</code> means cursor is on <code>x</code>):</p>
<pre><code>if (some_condition) {[ ]return; }
</code></pre>
<p>Occasionally, I might want to enter some more code. So I'd press <kbd>i</kbd> to get into insert mode, press <kbd>Enter</kbd> to insert the line break and then delete the extra space. Next, I'd enter normal mode and position the cursor before the closing brace and then do the same thing to get it on its own line.</p>
<p>I've been doing this a while, but there's surely a better way to do it?</p>

<p>I have a local Git repository I've been developing under for a few days: it has eighteen commits so far. Tonight, I created a private Github repository I was hoping to push it to; however, when I did so, it only ended up pushing eight of the eighteen commits to Github. I deleted the Github repo and retried, with the same result.</p>
<p>Any thoughts on why this might be happening? I've done this procedure before without a few times successfully, so I'm a bit stumped.</p>
<p><strong>Update</strong>: There is, and has always been, only the master branch in this repo. Just to address a few of the posted answers...</p>

<p>I'm attempting to use LINQ to insert a record into a child table and I'm
receiving a "Specified cast is not valid" error that has something to do w/
the keys involved. The stack trace is:</p>
<blockquote>
<p>Message: Specified cast is not valid.</p>

</blockquote>
<p>This error is being thrown on the following code:</p>
<pre><code> ResponseDataContext db = new ResponseDataContext(m_ConnectionString);
CodebookVersion codebookVersion = db.CodebookVersions.Single(cv => cv.VersionTag == m_CodebookVersionTag);
ResponseCode rc = new ResponseCode()
{
SurveyQuestionName = "Q11",
Code = 3,
Description = "Yet another code"
};
codebookVersion.ResponseCodes.Add(rc);
db.SubmitChanges(); //exception gets thrown here
</code></pre>
<p>The tables in question have a FK relationship between the two of them.<br>
The parent table's column is called 'id', is the PK, and is of type: INT NOT NULL IDENTITY<br>
The child table's column is called 'responseCodeTableId' and is of type: INT NOT NULL.</p>
<p>codebookVersion (parent class) maps to table tblResponseCodeTable<br>
responseCode (childClass) maps to table tblResponseCode</p>
<p>If I execute SQL directly, it works. e.g. </p>
<pre><code>INSERT INTO tblResponseCode
(responseCodeTableId, surveyQuestionName, code, description)
VALUES (13683, 'Q11', 3, 'Yet another code')
</code></pre>
<p>Updates to the same class work properly. e.g. </p>
<pre><code>codebookVersion.ResponseCodes[0].Description = "BlahBlahBlah";
db.SubmitChanges(); //no exception - change is committed to db
</code></pre>
<p>I've examined the variable, rc, after the .Add() operation and it does, indeed, receive the proper responseCodeTableId, just as I would expect since I'm adding it to that collection.</p>
<pre><code>tblResponseCodeTable's full definition:
COLUMN_NAME TYPE_NAME
id int identity
responseCodeTableId int
surveyQuestionName nvarchar
code smallint
description nvarchar
dtCreate smalldatetime
</code></pre>
<p>dtCreate has a default value of GetDate().</p>
<p>The only other bit of useful information that I can think of is that no SQL
is ever tried against the database, so LINQ is blowing up before it ever
tries (hence the error not being a SqlException). I've profiled and verified
that no attempt is made to execute any statements on the database.</p>
<p>I've read around and seen the problem when you have a relationship to a non PK field, but that doesn't fit my case.</p>
<p>Can anyone shed any light on this situation for me? What incredibly obvious thing am I missing here? </p>
<p>Many thanks.<br>
Paul Prewett</p>

<p>I have a base class with a property which (the get method) I want to overwrite in the subclass. My first thought was something like:</p>
<pre><code>class Foo(object):
def _get_age(self):
return 11
age = property(_get_age)
class Bar(Foo):
def _get_age(self):
return 44
</code></pre>
<p>This does not work (subclass bar.age returns 11). I found a solution with an lambda expression which works:</p>
<pre><code>age = property(lambda self: self._get_age())
</code></pre>
<p>So is this the right solution for using properties and overwrite them in a subclass, or are there other preferred ways to do this?</p>

<p>I have a problem whereby I want to display a view differently (a different master page), depending on where it came from, but don't know where to start...</p>
<p>I have several routes which catch various different types of urls that contain different structures.</p>
<p>In the code snippet below, I have a product route, and then I have a partner site route which could also go to a product page, but let's say that this partner is Pepsi, and they want their branding on the master page, rather than our own default styling. Lets say I go to <a href="http://mysite.com/products/cola.htm" rel="nofollow noreferrer">products/cola.htm</a>. This should go to the same url as <a href="http://mysite.com/partners/pepsi/products/cola.htm" rel="nofollow noreferrer">partners/pepsi/products/cola.htm</a>, and the PartnerRedirect would be able to handle the url based on the wildcard, by translating the url wildcard (in this case, "products/cola.htm") into a controller action, and forward the user on, (but simply change the master page in the view).</p>
<pre><code>routes.MapRoute(
"Product",
"products/{product}.htm",
new { controller = "Product", action = "ShowProduct" }
);
routes.MapRoute(
"ProductReview",
"products/{product}/reviews.htm",
new { controller = "Product", action = "ShowProductReview" }
);
routes.MapRoute(
"Partner",
"partners/{partner}/{*wildcard}",
new { controller = "Partners", action = "PartnerRedirect" }
);
</code></pre>
<p>Is this possible? And if so, how?</p>
<p>Many thanks in advance.</p>

<p>Many languages have a facility to check to see if an Object is of a certain type (including parent subclasses), implemented with 'is' and used like this:</p>
<pre><code>if(obj is MyType)
</code></pre>
<p>Or slightly more tediously you can in other languages check by using the 'as' keyword to do a soft typecast and seeing if the result null. </p>
<p>I haven't used Java in years and I'm getting back up to speed on it but surely Java has a way to easily do this without delving deep into the Reflection APIs?</p>
<p>Thanks in advance for answers. I have searched both here and other places but the keywords involved are so generic that even though I'm sure this has a simple answer, googling for it is hard.</p>

<p>I am working with a peripheral device that needs to be communicated through serial. I can send it commands using HyperTerminal, but now I need to write programs that will let me do it without HyperTerminal. Can somebody point me to a website and/or show me a sample hello world program to get me started? I have searched through many sites which give me uncompilable/ancient VC6 code.</p>

<p>I'm using GCC; __FILE__ returns the current source file's entire path and name: <code>/path/to/file.cpp</code>. Is there a way to get just the file's name <code>file.cpp</code> (without its path) at compile time? Is it possible to do this in a portable way? Can template meta programming be applied to strings?</p>
<p>I am using this in an error logging macro. I really do not want my source's full path making its way into the executable.</p>

<p>Edit: This code is fine. I found a logic bug somewhere that doesn't exist in my pseudo code. I was blaming it on my lack of Java experience.</p>
<p>In the <strong>pseudo code</strong> below, I'm trying to parse the XML shown. A silly example maybe but my code was too large/specific for anyone to get any real value out of seeing it and learning from answers posted. So, this is more entertaining and hopefully others can learn from the answer as well as me.</p>
<p>I'm new to Java but an experienced C++ programmer which makes me believe my problem lies in my understanding of the Java language.</p>
<p>Problem: When the parser finishes, my Vector is full of uninitialized Cows. I create the Vector of Cows with a default capacity (which shouldn't effect it's "size" if it's anything like C++ STL Vector). When I print the contents of the Cow Vector out after the parse, it gives the right size of Vector but all the values appear never to have been set.</p>
<p>Info: I have successfully done this with other parsers that don't have Vector <em>fields</em> but in this case, I'd like to use a Vector to accumulate Cow properties.</p>
<p>MoreInfo: I can't use generics (Vector< Cow >) so please don't point me there. :)</p>
<p>Thanks in advance.</p>

<p>At what point would you create your own exception class vs. using java.lang.Exception? (All the time? Only if it will be used outside the package? Only if it must contain advanced logic? etc...)</p>

<p>I'm new with Objective-C, so there probably is a simple solution to this.</p>
<p>I want a number to increment, but each iteration to be show on a label. (for example, it shows 1, 2, 3, 4, 5... displayed apart by an amount of time).</p>
<p>I tried:</p>
<pre><code>#import "testNums.h"
@implementation testNums
- (IBAction)start:(id)sender {
int i;
for(i = 0; i < 10; ++i)
{
[outputNum setIntValue:i];
sleep(1);
}
}
@end
</code></pre>
<p>and all it did was wait for 9 seconds (apparently frozen) and then displayed 9 in the text box.</p>

<p>I have two PHP files that I need to link. How can I link the files together using PHP? The effect I want is to have the user click a button, some information is proccessed on the page, and then the result is displayed in a different page, depending on the button the user clicked.Thanks</p>

<p>Here's what I am trying to do:</p>
<p>Select text from a webpage I pulled up using my web browser control.After clicking a button while this text is still selected I would like a message box to pop-up displaying the text that was highlighted by the user. How do I get this functionality to work in my wpf application?</p>
<p>I think I'm on the right track using mshtml but I get an error that says:</p>
<blockquote>
<p>Error HRESULT E_FAIL has been returned from a call to a COM component.</p>
</blockquote>
<p>This error will happen even when I try something small on the document like changing the title.</p>
<p>The code is below:</p>
<pre><code>IHTMLDocument2 doc = (IHTMLDocument2)this.webBookText.Document;
doc.title = "l";
</code></pre>

<p>I been waiting for sometime now to bring my Asp.net Preview 4 project up to snuff, totally skipping Preview 5 just because I knew I would have some issues.</p>
<p>Anyhow, here is the question and dilemma.</p>
<p>I have a few areas on the site which I have an ajax update type panel that renders content from a view using this technique found here. <a href="http://www.singingeels.com/Articles/AJAX_Panels_with_ASPNET_MVC.aspx" rel="nofollow noreferrer">AJAX Panels with ASP.NET MVC</a></p>
<p>This worked fine in preview 4 but now in the beta I keep getting this ..</p>
<pre><code>Sys.ArgumentNullException: Value cannot be null Parameter name eventObject
</code></pre>
<p>It has been driving me nuts... </p>
<p>My code looks like this</p>
<pre><code><% using (this.Ajax.BeginForm("ReportOne", "Reports", null, new AjaxOptions { UpdateTargetId = "panel1" }, new { id = "panelOneForm" })) { } %>
<div class="panel" id="panel1"><img src="/Content/ajax-loader.gif" /></div>
<script type="text/javascript">
$get("panelOneForm").onsubmit();
</script>
</code></pre>
<p>so basically what its doing is forcing the submit on the form, which updates panel1 with the contents from the view ReportOne.</p>
<p>What am I missing? Why am I getting this error? Why did they go and change things? I love MVC but this is making me crazy.</p>

<p>So lets say I'm using Python's <a href="http://www.python.org/doc/2.5.2/lib/module-ftplib.html" rel="nofollow noreferrer">ftplib</a> to retrieve a list of log files from an FTP server. How would I parse that list of files to get just the file names (the last column) inside a list? See the link above for example output.</p>

<p>In cmd.exe, I can execute the command "copy c:\hello.txt c:\hello2.txt" and it worked fine.
But in my C program, I ran this piece of code and got the following error:</p>
<pre><code>#include <iostream>
using namespace std;
int main()
{
system("copy c:\hello.txt c:\hello2.txt");
system("pause");
return 0;
}
</code></pre>
<p>Output:
The system cannot find the file specified.</p>
<p>Anybody know what is going on here?</p>

<p>std::next_permutation (and std::prev_permutation) permute all values in the range <code>[first, last)</code> given for a total of n! permutations (assuming that all elements are unique).</p>
<p>is it possible to write a function like this:</p>
<pre><code>template<class Iter>
bool next_permutation(Iter first, Iter last, Iter choice_last);
</code></pre>
<p>That permutes the elements in the range <code>[first, last)</code> but only chooses elements in the range <code>[first, choice_last)</code>. ie we have maybe 20 elements and want to iterate through all permutations of 10 choices of them, 20 P 10 options vs 20 P 20.</p>
<ul>
<li>Iter is a random access iterator for my purposes, but if it can be implemented as a bidirectional iterator, then great!</li>
<li>The less amount of external memory needed the better, but for my purposes it doesn't matter.</li>
<li>The chosen elements on each iteration are input to the first elements of the sequence.</li>
</ul>
<p><em>Is such a function possible to implement? Does anyone know of any existing implementations?</em></p>
<p>Here is essentially what I am doing to hack around this. Suggestions on how to improve this are also welcome.</p>
<ul>
<li>Start with a vector <code>V</code> of <code>N</code> elements of which I want to visit each permutation of <code>R</code> elements chosen from it (<code>R <= N</code>).</li>
<li>Build a vector <code>I</code> of length <code>R</code> with values <code>{ 0, 1, 2, ... R - 1 }</code> to serve as an index to the elements of <code>V</code></li>
<li>On each iteration, build a vector <code>C</code> of length <code>R</code> with values <code>{ V[I[0]], V[I[1]], ... V[I[R - 1]] }</code></li>
<li>Do something with the values in <code>C</code>.</li>
<li>Apply a function to permute the elements of <code>I</code> and iterate again if it was able to.</li>
</ul>
<p>That function looks like this:</p>
<pre><code>bool NextPermutationIndices(std::vector<int> &I, int N)
{
const int R = I.size();
for (int i = R - 1; ; --i) {
if (I[i] < N - R + i) {
++I[i];
return true;
}
if (i == 0)
return false;
if (I[i] > I[i-1] + 1) {
++I[i-1];
for (int j = i; j < R; ++j)
I[j] = I[j-1] + 1;
return true;
}
}
}
</code></pre>
<p>That function is very complicated due to all the possible off-by-one errors, as well everything using it are more complicated than is probably necessary.</p>
<hr>
<p><strong><em>EDIT:</em></strong></p>
<p>It turns out that it was <strong>significantly</strong> easier than I had even imagined. From <a href="http://photon.poly.edu/~hbr/boost/combinations.html" rel="nofollow noreferrer">here</a>, I was able to find exact implementations of many of the exact algorithms I needed (combinations, permutations, etc.).</p>
<pre><code>template<class BidirectionalIterator>
bool next_partial_permutation(BidirectionalIterator first,
BidirectionalIterator middle,
BidirectionalIterator last)
{
std::reverse(middle, last);
return std::next_permutation(first, last);
}
</code></pre>
<p>Plus there is a combination algorithm there that works in a similar way. The implementation of that is much more complication though.</p>

<p>I've been a bad programmer because I am doing a copy and paste. An example is that everytime i connect to a database and retrieve a recordset, I will copy the previous code and edit, copy the code that sets the datagridview and edit. I am aware of the phrase code reuse, but I have not actually used it. How can i utilize code reuse so that I don't have to copy and paste the database code and the datagridview code.,</p>

<p>I have a php script that is executing an executable that writes to a serial port.
However, everytime it runs <pre>system("c:\Untitled1.exe")</pre>
it just opens up a cmd window and freezes.</p>
<p>Anybody know how to fix this? Or if there is an easier way to get PHP to write to the serial port directly? (I've already tried these two: <a href="http://blogs.vinuthomas.com/2007/04/09/php-and-serial-ports/" rel="nofollow noreferrer">http://blogs.vinuthomas.com/2007/04/09/php-and-serial-ports/</a> and they don't work for me)</p>
<p>P.S. I am on Windows XP</p>

<p>I have a CSV file that has a column that contains strings that look like integers. That is they should be dealt with as strings, but since they are numbers they appear to be imported as integers (dropping off the leading zeroes).</p>
<p>Example Data:</p>
<ul>
<li>0000000000079</li>
<li>0000999000012</li>
<li>0001002000005 </li>
<li>0004100000007</li>
</ul>
<p>The problem I'm seeing is that the last example data point comes through as DBNull.Value. I'm assuming this is because OleDB is treating that column as an integer (the data points come through without their leading zeroes also) and that 0004100000007 is greater than the largest integer value.</p>
<p>Is there some way to say "column [0] is a string, don't read it as an integer"? When reading the data?</p>
<p>The code I am currently using is:</p>
<pre><code>OleDbConnection dbConn = new OleDbConnection(SourceConnectionString);
OleDbCommand dbCommand = new OleDbCommand("SELECT * FROM test.csv", dbConn);
dbConn.Open();
OleDbDataReader dbReader = dbCommand.ExecuteReader();
while (dbReader.Read())
{
if (dbReader[0] != DBNull.Value)
{
// do some work
}
}
</code></pre>

<p><a href="http://en.wikipedia.org/wiki/C%2B%2B11" rel="noreferrer">C++11</a> introduces <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2378.pdf" rel="noreferrer">user-defined literals</a> which will allow the introduction of new literal syntax based on existing literals (<code>int</code>, <code>hex</code>, <code>string</code>, <code>float</code>) so that any type will be able to have a literal presentation.</p>
<p><strong>Examples:</strong></p>
<pre><code>// imaginary numbers
std::complex<long double> operator "" _i(long double d) // cooked form
{
return std::complex<long double>(0, d);
}
auto val = 3.14_i; // val = complex<long double>(0, 3.14)
// binary values
int operator "" _B(const char*); // raw form
int answer = 101010_B; // answer = 42
// std::string
std::string operator "" _s(const char* str, size_t /*length*/)
{
return std::string(str);
}
auto hi = "hello"_s + " world"; // + works, "hello"_s is a string not a pointer
// units
assert(1_kg == 2.2_lb); // give or take 0.00462262 pounds
</code></pre>
<p>At first glance this looks very cool but I'm wondering how applicable it really is, when I tried to think of having the suffixes <code>_AD</code> and <code>_BC</code> create dates I found that it's problematic due to operator order. <code>1974/01/06_AD</code> would first evaluate <code>1974/01</code> (as plain <code>int</code>s) and only later the <code>06_AD</code> (to say nothing of August and September having to be written without the <code>0</code> for octal reasons). This can be worked around by having the syntax be <code>1974-1/6_AD</code> so that the operator evaluation order works but it's clunky. </p>
<p>So what my question boils down to is this, do you feel this feature will justify itself? What other literals would you like to define that will make your C++ code more readable?</p>
<hr>
<p>Updated syntax to fit the final draft on June 2011</p>

<p>How can I send the <code>close_notify</code> alert manually?</p>

<p>Say each row in a table has data pertaining to one particular user. The user has a password to access the system.</p>
<p>How do I encrypt a column of data using InnoDB so that no one other than the user who's data it is can read the data ? I was thinking of something like using one of the MySQL encryption functions (say AES) with a key based on a hash calculated from the user's password.</p>
<p>Does any one have any pointers to how I could do this ? Am I on the right track ?</p>
<p>One of the answers below</p>
<blockquote>
<p>The issue of modifying user's password involves re-encrypting the user key by means of the new password which is much more straight forward than re-encrypting the whole bunch of user's data that can be arbitrarily large. The user key remains the same accross the life of the user data in the system.</p>
</blockquote>
<p>How does this help ? Say the password is pass1. And there are a bunch of records encrypted with a key generated from this. If the user now resets the password to pass2, I have no way of decrypting the data that was encrypted using pass1. In the case of a user forgetting the password entirely, all his encrypted data will be lost.</p>

<p>I have a text box in wxPython that takes the output of dictionary.items() and displays it to the user as items are added to the dictionary. However, the raw data is very ugly, looking like </p>
<pre><code>[(u'BC',45)
(u'CHM',25)
(u'CPM',30)]
</code></pre>
<p>I know dictionary.items() is a list of tuples, but I can't seem to figure out how to make a nice format that is also compatible with the SetValue() method of wxPython.</p>
<p>I've tried iterating through the list and tuples. If I use a <em>print</em> statement, the output is fine. But when I replace the <em>print</em> statement with SetValue(), it only seems to get the last value of each tuple, rather than both items in the tuple.</p>
<p>I've also tried creating a string and passing that string to SetValue() but, again, I can only get one item in the tuple or the other, not both.</p>
<p>Any suggestions?</p>
<hr>
<p><strong>Edit:</strong> Yes, I am passing the results of the dictionary.items() to a text field in a wxPython application. Rather than having the results like above, I'm simply looking for something like:</p>
<pre><code>BC 45
CHM 25
CMP 30
</code></pre>
<p>Nothing special, just simply pulling each value from each tuple and making a visual list.</p>
<p>I have tried making a string format and passing that to SetValue() but it gets hung up on the two values in the tuple. It will either double print each string and add the integers together or it simply returns the integer, depending on how I format it.</p>

<p>I'm making a game and one of the methods calculates a character's base hit numbers based on skill values. The method currently calculates each value individually, since each skill can be used at short, medium, and long range.</p>
<p>I originally thought I could combine the skills into a tuple and iterate over it, dynamically creating each hit number. But I don't know if it's actually possible, since I currently have each hit number assigned to it's own variable.</p>
<p>I also thought about creating a method for each range, and passing the tuple as an argument. I could create a new tuple or list with the resulting values and then assign them to the individual variables, but I don't see how it would be any better than do it this way, except that it won't look so copy & pasted.</p>
<p>Here's what I currently have:</p>
<pre><code> def calcBaseHitNumbers(self, dict):
"""Calculate character's base hit numbers depending on skill level."""
self.skill_dict = dict
self.rifle = self.skill_dict.get('CRM', 0)
self.pistol = self.skill_dict.get('PST', 0)
self.big_gun = self.skill_dict.get('LCG', 0)
self.heavy_weapon = self.skill_dict.get('HW', 0)
self.bow = self.skill_dict.get('LB', 0)
#self.skill_tuple = (self.rifle, self.pistol, self.big_gun, self.heavy_weapon,
# self.bow)
#---Short range
## for skill in self.skill_tuple:
## self.base_hit_short = skill * 0.6
self.charAttribs.bhCRM_short = self.rifle * 0.6
self.charAttribs.bhPST_short = self.pistol * 0.6
self.charAttribs.bhHW_short = self.heavy_weapon * 0.6
self.charAttribs.bhLCG_short = self.big_gun * 0.6
self.charAttribs.bhLB_short = self.bow * 0.6
#---Med range
self.charAttribs.bhCRM_med = self.rifle * 0.3
self.charAttribs.bhPST_med = self.pistol * 0.3
self.charAttribs.bhHW_med = self.heavy_weapon * 0.3
self.charAttribs.bhLCG_med = self.big_gun * 0.3
self.charAttribs.bhLB_med = self.bow * 0.3
#---Long range
self.charAttribs.bhCRM_long = self.rifle * 0.1
self.charAttribs.bhPST_long = self.pistol * 0.1
self.charAttribs.bhHW_long = self.heavy_weapon * 0.1
self.charAttribs.bhLCG_long = self.big_gun * 0.1
self.charAttribs.bhLB_long = self.bow * 0.1
</code></pre>
<p>How would you refactor this so it's more dynamic?</p>
<hr>
<p><strong>Edit:</strong> I guess what I want to do is something like this:
Have a tuple (like the one I commented out) and iterate over it 3 times, each time making a new value (for each skill) based on the modifier for each particular range. The resulting value is then automatically assigned to it's respective variable.</p>
<p>In my head, it makes sense. But when I actually try to code it, I get lost. The problem, I think, is that this is the first "real" program I've written; all I've done before are small scripts.</p>
<p>This is only the 0.1 version of my program, so it's not critical to refactor it now. However, it seems very un-Pythonic to do this manually and I also want to "future-proof" this in case things change down the road.</p>

<p>I am using freeglut for opengl rendering...</p>
<p>I need to draw an envelop looking like a cone (2D) that has to be filled with some color and some transparency applied.</p>
<p>Is the freeglut toolkit equipped with such an inbuilt functionality to draw filled geometries(or some trick)?
or is there some other api that has an inbuilt support for filled up geometries..</p>
<p><strong>Edit1:</strong>
just to clarify the 2D cone thing... the envelop is the graphical interpretation of the coverage area of an aircraft during interception(of an enemy aircraft)...that resembles a sector of a circle..i should have mentioned sector instead..</p>
<p>and glutSolidCone doesnot help me as i want to draw a filled sector of a circle...which i have already done...what remains to do is to fill it with some color...
how to fill geometries with color in opengl?</p>
<p><strong>Edit2:</strong>
All the answers posted to this questions can work for my problem in a way..
But i would definitely would want to know a way how to fill a geometry with some color.
Say if i want to draw an envelop which is a parabola...in that case there would be no default glut function to actually draw a filled parabola(or is there any?)..
So to generalise this question...how to draw a custom geometry in some solid color?</p>
<p><strong>Edit3:</strong>
The answer that mstrobl posted works for GL_TRIANGLES but for such a code:</p>
<pre><code>glBegin(GL_LINE_STRIP);
glColor3f(0.0, 0.0, 1.0);
glVertex3f(0.0, 0.0, 0.0);
glColor3f(0.0, 0.0, 1.0);
glVertex3f(200.0, 0.0, 0.0);
glColor3f(0.0, 0.0, 1.0);
glVertex3f(200.0, 200.0, 0.0);
glColor3f(0.0, 0.0, 1.0);
glVertex3f(0.0, 200.0, 0.0);
glColor3f(0.0, 0.0, 1.0);
glVertex3f(0.0, 0.0, 0.0);
glEnd();
</code></pre>
<p>which draws a square...only a wired square is drawn...i need to fill it with blue color.</p>
<p>anyway to do it?</p>
<p>if i put some drawing commands for a closed curve..like a pie..and i need to fill it with a color is there a way to make it possible...</p>
<p>i dont know how its possible for GL_TRIANGLES... but how to do it for any closed curve?</p>

<p>Ok, I am trying to use Tail to monitor a log file, but I cannot get the same behavior programatically as when I manually run it through cmd prompt using the same parameters.</p>
<p>When run through cmd prompt it displays the new lines <strong>instantly</strong>. Programatically though, I have to wait for about <strong>75+ new lines</strong> in log file before the 'buffer' unleashes all the lines.</p>
<p>Here's the code I have now.</p>
<pre><code>private const string tailExecutable = @"C:\tail.exe";
private const string logFile = @"C:\test.log";
private static void ReadStdOut()
{
var psi = new ProcessStartInfo
{
FileName = tailExecutable,
Arguments = String.Format("-f \"{0}\"", logFile),
UseShellExecute = false,
RedirectStandardOutput = true
};
// Running same exe -args through cmd.exe
// works perfectly, but not programmatically.
Console.WriteLine("{0} {1}", psi.FileName, psi.Arguments);
var tail = new Process();
tail.StartInfo = psi;
tail.OutputDataReceived += tail_OutputDataReceived;
tail.Start();
tail.BeginOutputReadLine();
}
static void tail_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
Console.WriteLine(e.Data);
}
</code></pre>
<p>I have used the OutputDataReceived event before but never had these buffering/spamming problems.</p>
<p>I am so confused with about right now.</p>
<h2>* <strong>Edit</strong> *</h2>
<p>I found <a href="http://www.codeproject.com/KB/cs/wintail.aspx" rel="nofollow noreferrer">this wintail project on CodeProject</a> and am going to be switching to that because the buffer makes this solution way too slow.</p>
<p>Thanks for the answers.</p>

<p>I have a tabview controller to which I added a UIViewController to each tab. I want to have multiple UIViews inside the UIViewController.</p>
<p>So in the implementation of the UIViewController class I added [self.view addSubView:uiview1] and [self.view addSubView:uiview2]. The problem is that when I run the app, it crahes on load.</p>
<p>However, if I only used a single UIView and did: self.view = UIView1 that would work fine.</p>
<p>Does anyone know what is causing the problem? Or if I'm doing something fundamentally wrong?</p>

<p>The framework I am developing for my application relies very heavily on dynamically generated domain objects. I recently started using Spring WebFlow and now need to be able to serialize my domain objects that will be kept in flow scope. </p>
<p>I have done a bit of research and figured out that I can use <code>writeReplace()</code> and <code>readResolve()</code>. The only catch is that I need to look-up a factory in the Spring context. I tried to use <code>@Configurable(preConstruction = true)</code> in conjunction with the BeanFactoryAware marker interface. </p>
<p>But <code>beanFactory</code> is always <code>null</code> when I try to use it in my <code>createEntity()</code> method. Neither the default constructor nor the <code>setBeanFactory()</code> injector are called.</p>
<p>Has anybody tried this or something similar? I have included relevant class below.</p>
<p>Thanks in advance,
Brian</p>

<p>This is probably one of those easy questions.. I'm trying to redirect the user after they've successfully authenticated, or return them back to the login page. But the Success page is on a different route and I can't get the redirection to work..</p>
<p>Here are my routes in Globals.asax:</p>
<pre><code>routes.MapRoute( _
"Default", _
"{controller}/{action}/{id}", _
New With {.controller = "Login", .action = "Index", .id = ""} _
)
routes.MapRoute( _
"Stuff", _
"{controller}/{action}/{id}", _
New With {.controller = "Stuff", .action = "Index", .id = ""} _
)
</code></pre>
<p>I've got 2 Controllers: <code>LoginController.vb</code> and <code>StuffController.vb</code>. The <code>Views/Login/Index.aspx</code> file contains a simple form with the code:</p>
<pre><code><form method="post" action="/Login/Authenticate">
</code></pre>
<p>The <code>LoginController</code> contains the following code:</p>
<pre><code>Function Authenticate() As RedirectToRouteResult
' authentication code commented out ;o)
Return RedirectToRoute("Stuff")
End Function
</code></pre>
<p>And the StuffController contains the following:</p>
<pre><code>Function Index()
' show stuff..
Return View() ' return /Views/Stuff/Index.aspx
End Function
</code></pre>
<p>Here's what I've tried so far:</p>
<ul>
<li>Function Authenticate()</li>
<li>Function Authenticate() As ActionResult()</li>
<li>Function Authenticate() As RedirectToRouteResult()</li>
</ul>
<p>all of which cause a Redirect Loop timeout in the browser. What am I missing?!</p>

<p>An <a href="https://stackoverflow.com/questions/61278/quick-and-dirty-way-to-profile-your-code#231614">answer to one of my questions</a> included the following line of code:</p>
<pre><code>label = std::safe_string(name); // label is a std::string
</code></pre>
<p>The intent seems to be a wrapper around a string literal (so presumably no allocation takes place). I've never heard of <code>safe_string</code> and neither, apparently, has <a href="http://www.google.com/search?q=%22std%3A%3Asafe_string%22" rel="nofollow noreferrer">google</a> (nor could I find it in the 98 standard). </p>
<p>Does anyone know what this is about?</p>

<p>I'm a recent semi-convert to Eclipse after 20 years of using vi and gvim. One of the things I miss about gvim is that I could cut a bunch of different snippets of code into named buffers, and paste them at will when doing something like repeating a common idiom. For instance I'd have it so <code>"ap</code> would paste</p>
<pre><code>DatabaseHandle handle = null;
try
{
handle = DatabaseConnectionPool.newHandle();
</code></pre>
<p>and then <code>"bp</code> would paste</p>
<pre><code> handle.commit();
}
finally
{
handle.rollback();
DatabaseConnectionPool.returnHandle(handle);
}
</code></pre>
<p>And I could repeat both of them over and over in the course of a day. In an answer to another question, somebody mentioned that you could "manage code snippets" in Eclipse, but didn't mention how. So now I'm asking: how do you manage code snippets in Eclipse? </p>
