187,453 | <p>Would it suppose any difference regarding overhead to write an import loading all the types within one package (<code>import java.*</code>); than just a specific type (i.e. <code>import java.lang.ClassLoader</code>)? Would the second one be a more advisable way to use than the other one?</p>

187,465 | <p>Any ideas how i can best drive a USB POS printer from c#.
POS printers are usually serial, TCP/IP or USB based.
I know how to accomplish serial and TCP/IP but have no idea about communications through USB in C#.
I know that there is a layer available from Microsoft called POS.NET, but I want to try and avoid using this.
Any ideas or any C# libraries that people can recomend would be really appreciated. Thanks</p>

187,482 | <p>I'd like to use the newer <code><button></code> tag in an ASP.NET website which, among other things, allows CSS-styled text and embedding a graphic inside the button. The asp:Button control renders as <code><input type="button"></code>, is there any way to make a preexisting control render to <code><button></code>?</p>
<p>From what I've read there is an incompatibility with IE posting the button's markup instead of the value attribute when the button is located within a <code><form></code>, but in ASP.NET it will be using the onclick event to fire __doPostBack anyway, so I don't think that this would be a problem.</p>
<p>Are there any reasons why I shouldn't use this? If not, how would you go about supporting it with asp:Button, or a new server control based on it? I would prefer to not write my own server control if that can be avoided.</p>
<hr>
<p>At first the <code><button runat="server"></code> solution worked, but I immediately ran into a situation where it needs to have a CommandName property, which the HtmlButton control doesn't have. It looks like I'm going to need to create a control inherited from Button after all. </p>
<p>What do I need to do in order to override the render method and make it render what I want?</p>
<hr>
<p><strong>UPDATE</strong></p>
<p>DanHerbert's reply has made me interested in finding a solution to this again, so I've spent some more time working on it. </p>
<p>First, there's a far easier way of overloading the TagName:</p>
<pre><code>public ModernButton() : base(HtmlTextWriterTag.Button)
{
}
</code></pre>
<p>The problem with Dan's solution as it stands is the innerhtml of the tag is placed into the value property, which causes a validation error on postback. A related problem is, even if you render the value property correctly, IE's braindead implementation of the <code><button></code> tag posts the innerhtml instead of the value anyway. So, any implementation of this needs to override the AddAttributesToRender method in order to correctly render the value property, and also provide some sort of workaround for IE so it doesn't completely screw up the postback.</p>
<p>The IE problem may be insurmountable if you want to take advantage of the CommandName/CommandArgument properties for a databound control. Hopefully someone can suggest a workaround for this.</p>
<p>I have made progress on the rendering:</p>
<p><a href="http://gist.github.com/69841" rel="noreferrer">ModernButton.cs</a></p>
<p>This renders as a proper html <code><button></code> with the correct value, but it doesn't work with the ASP.Net PostBack system. I've written some of what I need to provide the <code>Command</code> event, but it doesn't fire.</p>
<p>When inspecting this button side-by-side with a regular asp:Button, they look the same other than the differences I need. So I'm not sure how ASP.Net is wiring up the <code>Command</code> event in this case.</p>
<p>An additional problem is, nested server controls aren't rendered (as you can see with the ParseChildren(false) attribute). It's pretty easy to inject literal html text into the control during render, but how do you allow support for nested server controls?</p>

187,505 | <p>I have few different applications among which I'd like to share a C# enum. I can't quite figure out how to share an enum declaration between a regular application and a WCF service. </p>
<p>Here's the situation. I have 2 lightweight C# destop apps and a WCF webservice that all need to share enum values. </p>
<p>Client 1 has </p>
<pre><code> Method1( MyEnum e, string sUserId );
</code></pre>
<p>Client 2 has </p>
<pre><code>Method2( MyEnum e, string sUserId );
</code></pre>
<p>Webservice has </p>
<pre><code>ServiceMethod1( MyEnum e, string sUserId, string sSomeData);
</code></pre>
<p>My initial though was to create a library called Common.dll to encapsulate the enum and then just reference that library in all of the projects where the enum is needed. However, WCF makes things difficult because you need to markup the enum for it to be an integral part of the service. Like this: </p>
<pre><code>[ServiceContract]
[ServiceKnownType(typeof(MyEnum))]
public interface IMyService
{
[OperationContract]
ServiceMethod1( MyEnum e, string sUserId, string sSomeData);
}
[DataContract]
public enum MyEnum{ [EnumMember] red, [EnumMember] green, [EnumMember] blue };
</code></pre>
<p>So .... Is there a way to share an enum among a WCF service and other applictions? </p>

187,506 | <p>I'm involved with updating an Access solution. It has a good amount of VBA, a number of queries, a small amount of tables, and a few forms for data entry & report generation. It's an ideal candidate for Access.</p>
<p>I want to make changes to the table design, the VBA, the queries, and the forms. How can I track my changes with version control? (we use Subversion, but this goes for any flavor) I can stick the entire mdb in subversion, but that will be storing a binary file, and I won't be able to tell that I just changed one line of VBA code.</p>
<p>I thought about copying the VBA code to separate files, and saving those, but I could see those quickly getting out of sync with what's in the database.</p>

187,531 | <p>I have a package that I just made and I have an "old-mode" that basically makes it work like it worked before: importing everything into the current namespace. One of the nice things about having this as a package is that we no longer have to do that. Anyway, what I would like to do is have it so that whenever anyone does:</p>
<pre><code>use Foo qw(:oldmode);
</code></pre>
<p>I throw a warning that this is deprecated and that they should either import only what they need or just access functions with Foo->fun();</p>
<p>Any ideas on how to do this?</p>

187,550 | <p>I have a lot of Java source code that requires custom pre-processing. I'd like rid of it but that's not feasible right now so I'm stuck with it. Given that I have an unfortunate problem that shouldn't have existed in the first place, how do I solve it using maven? </p>
<p>(For the full story, I'm replacing a python-based build system with a maven one, so one improvement at a time please. Fixing the non-standard source code is harder, and will come later.)</p>
<p>Is it possible using any existing Maven plugins to actually alter the source files during compile time? (Obviously leaving the original, unprocessed code alone)</p>
<p>To be clear, by preprocessing I mean preprocessing in the same sense as antenna or a C compiler would preprocess the code, and by custom I mean that it's completely proprietary and looks nothing at all like C or antenna preprocessing.</p>

There are a handful of 3rd party web parts and since this is a migration, not an in-place upgrade, I need to install these web parts on the new farm.</p>
<p>How do I do this, given that I have the packaged up web parts as provided by the SharePoint Configuration Analyzer in the form of cab files? Can I simply deploy these cab files somehow, even though they are not packaged as solutions? Or do I need to pull the cab files apart and repackage them as solutions? Or do I need to get new versions of the web parts, written for SharePoint 3, and maybe edit the pages that use them?</p>

187,576 | <p>I am developing a little app that retrieves an XML file, located on a remote server (<code>http://example.com/myfile.xml</code>)
This file is relatively big, and it contains a big list of geolocations with other information that I need to use for my app.
So I read this file remotely once and insert it into a little SqlCE file (<code>database.sdf</code>)</p>
<p>So If I need to be accessing geolocation #1, I ll just make a SELECT statement into this DATABASE instead of loading the whole XML file every time.</p>
<p>But I would like to know if its possible to do this without using .sdf files?</p>
<p>What is the most efficient way (fastest)?</p>
<p>Saving the big XML file once locally and load if every time I start my app to load it in a data set? this is would make the app a bit long to load every time</p>
<p>Saving the big XML file once locally and reading the nodes one by one to look for geolocation #1?</p>

187,583 | <p>I have one std::list<> container and these threads:</p>
<ul>
<li><p>One writer thread which adds elements indefinitely.</p></li>
<li><p>One reader/writer thread which reads and removes elements while available.</p></li>
<li><p>Several reader threads which access the SIZE of the container (by using the size() method)</p></li>
</ul>
<p>There is a normal mutex which protects the access to the list from the first two threads. My question is, do the size reader threads need to acquire this mutex too? should I use a read/write mutex?</p>
<p>I'm in a windows environment using Visual C++ 6.</p>
<p><strong>Update</strong>: It looks like the answer is not clear yet. To sum up the main doubt: Do I still need to protect the SIZE reader threads even if they only call size() (which returns a simple variable) taking into account that I don't need the exact value (i.e. I can assume a +/- 1 variation)? How a race condition could make my size() call return an invalid value (i.e. one totally unrelated to the good one)?</p>
<p><strong>Answer</strong>: In general, the reader threads must be protected to avoid race conditions. Nevertheless, in my opinion, some of the questions stated above in the update haven't been answered yet.</p>
<p>Thanks in advance! </p>
<p>Thank you all for your answers!</p>

187,621 | <p>I am aware of how to setup autocompletion of python objects in the python interpreter (on unix). </p>
<ul>
<li>Google shows many hits for explanations on how to do this.</li>
<li>Unfortunately, there are so many references to that it is difficult to find what I need to do, which is slightly different.</li>
</ul>
<p>I need to know how to enable, tab/auto completion of arbitrary items in a command-line program written in python.</p>
<p>My specific use case is a command-line python program that needs to send emails. I want to be able to autocomplete email addresses (I have the addresses on disk) when the user types part of it (and optionally presses the TAB key).</p>
<p>I do not need it to work on windows or mac, just linux.</p>

187,627 | <p>I'm trying to use a static library created by me in Visual C++ 2005 (unmanaged C++). I declare one function "int myF(int a);" into a .h file, I implement it in a .cpp file, I compile it - the .lib file is produced.</p>
<p>I create a new project (a separate solution) in VC++ 2005 (also native C++), I add the paths for the include file and the lib file; when I invoke the function myF the linker reports an error: "error LNK2019: unresolved external symbol _myF referenced in function _main". if I create the client project in the same solution as the library project and then add a reference to the library projects, it works, but I'm not going to implement everything like this, but rather to add external libraries to my projects...</p>
<p>What is wrong?</p>
<p>Thank you.</p>

187,633 | <p>First of all, I'd like to say that this site is great!</p>
<p>My question is, what are the reasons for the following 2 error messages?</p>
<p>1) In VB.NET (I know this is a C# forum but my next question is from C# experience), property evaluation failed (I do this when putting a watch on an exception variable).</p>
<p>2) In C#, method or class (Can't remember which) does not have a constructor. I think I got this with HttpContext or HttpApplication, which is a class if I remember correctly? Pretty sure it is as it has its own properties and methods.</p>
<p>Thanks</p>

187,640 | <p>Is it good practice to have a class constructor that uses default parameters, or should I use separate overloaded constructors? For example:</p>
<pre><code>// Use this...
class foo
{
private:
std::string name_;
unsigned int age_;
public:
foo(const std::string& name = "", const unsigned int age = 0) :
name_(name),
age_(age)
{
...
}
};
// Or this?
class foo
{
private:
std::string name_;
unsigned int age_;
public:
foo() :
name_(""),
age_(0)
{
}
foo(const std::string& name, const unsigned int age) :
name_(name),
age_(age)
{
...
}
};
</code></pre>
<p>Either version seems to work, e.g.:</p>
<pre><code>foo f1;
foo f2("Name", 30);
</code></pre>
<p>Which style do you prefer or recommend and why?</p>

187,669 | <p>I have a linker command file that assigns the top address of the stack into a variable </p>
<pre><code>_stack = . + 0x80000;

<p>I want to use this address in a 'c' program - I want to copy the stack to another location and then update the stack pointer to point to the new location before doing a destructive memory test on the orginal bank of RAM.</p>
<p>I'm finding that if I do something like</p>
<pre><code>extern u32 *_stack;
myFunction(_stack);
</code></pre>
<p>Then the function seems to get passed the value stored at the stack location </p>
<pre><code>lwz r3,0(r8)

<p>Rather than the address of the stack itself.
Can anyone help?</p>

<p>Strings are <em>immutable</em>--the contents of a string object cannot be changed after the object is created, although the syntax makes it appear as if you can do this. For example, when you write this code, the compiler actually creates a new string object to hold the new sequence of characters, <strong>and the variable b continues to hold "h"</strong>. </p>
<p>string b = "h";</p>
<p>b += "ello";</p>

187,713 | <p>In C++, what's the generic way to convert any floating point value (float) to <a href="http://en.wikipedia.org/wiki/Fixed-point_arithmetic" rel="noreferrer"><strong>fixed point</strong></a> (int, 16:16 or 24:8)?</p>
<p><strong>EDIT:</strong> For clarification, fixed-point values have two parts to them: an integer part and a fractional part. The integer part can be represented by a signed or unsigned integer data type. The fractional part is represented by an unsigned data integer data type.</p>
<p>Let's make an analogy with money for the sake of clarity. The fractional part may represent cents -- a fractional part of a dollar. The range of the 'cents' data type would be 0 to 99. If a 8-bit unsigned integer were to be used for fixed-point math, then the fractional part would be split into 256 evenly divisible parts.</p>
<p>I hope that clears things up.</p>

187,736 | <p>I'm writing a command line tool to help my web app. It needs a password to connect to the service. I'd like the script to show a password prompt so I don't have to pass it as a command line argument. </p>
<p>That's easy enough, but I'd like it to not echo the password to the screen as it's typed. How can I do this with PHP? </p>
<p>Bonus points for doing it in pure PHP (no <code>system('stty')</code>) and replacing the characters with <code>*</code>. </p>
<p><strong>EDIT:</strong></p>
<p>The script will run on a unix like system (linux or mac). The script is written in PHP, and will most likely stay like that.</p>
<p>Also, for the record, the <code>stty</code> way of doing it is:</p>
<pre><code>echo "Password: ";
system('stty -echo');
$password = trim(fgets(STDIN));
system('stty echo');
// add a new line since the users CR didn't echo
echo "\n";
</code></pre>
<p>I'd prefer to not have the <code>system()</code> calls in there.</p>

187,761 | <p>POSIX allows mutexes to be recursive. That means the same thread can lock the same mutex twice and won't deadlock. Of course it also needs to unlock it twice, otherwise no other thread can obtain the mutex. Not all systems supporting pthreads also support recursive mutexes, but if they want to be <a href="http://www.opengroup.org/onlinepubs/009695399/functions/pthread_mutexattr_gettype.html" rel="noreferrer">POSIX conform, they have to</a>.</p>
<p>Other APIs (more high level APIs) also usually offer mutexes, often called Locks. Some systems/languages (e.g. Cocoa Objective-C) offer both, recursive and non recursive mutexes. Some languages also only offer one or the other one. E.g. in Java mutexes are always recursive (the same thread may twice "synchronize" on the same object). Depending on what other thread functionality they offer, not having recursive mutexes might be no problem, as they can easily be written yourself (I already implemented recursive mutexes myself on the basis of more simple mutex/condition operations).</p>
<p>What I don't really understand: What are non-recursive mutexes good for? Why would I want to have a thread deadlock if it locks the same mutex twice? Even high level languages that could avoid that (e.g. testing if this will deadlock and throwing an exception if it does) usually don't do that. They will let the thread deadlock instead.</p>
<p>Is this only for cases, where I accidentally lock it twice and only unlock it once and in case of a recursive mutex, it would be harder to find the problem, so instead I have it deadlock immediately to see where the incorrect lock appears? But couldn't I do the same with having a lock counter returned when unlocking and in a situation, where I'm sure I released the last lock and the counter is not zero, I can throw an exception or log the problem? Or is there any other, more useful use-case of non recursive mutexes that I fail to see? Or is it maybe just performance, as a non-recursive mutex can be slightly faster than a recursive one? However, I tested this and the difference is really not that big.</p>

187,768 | <p>I've created a copy utility in c# (.NET 2.0 Framework) that copies files, directories and recursive sub directories etc. The program has a GUI that shows the current file being copied, the current file number (sequence), the total number of files to be copied and the percentage completed for the copy operations. There is also a progress bar, that is based on current file / total files.</p>
<p>My problem is related to copying large files. I've been unable to find a way to indicate the total copy progress of a large file (using my current class structure that utilitzes FileInfo.CopyTo method). As a workaround I've separated the file copy operations and GUI display to their own threads and set up a visual cue to show that work is being done. At least the user is aware that the program isn't frozen and is still copying files.</p>
<p>It would be nicer to be able to show the progress based on the total number of bytes or have some type of event that fires from the FileInfo.CopyTo method that indicates the total number of bytes copied from the current file.</p>
<p>I'm aware of the FileInfo.Length property, so I'm sure there is a way MacGuyver my own event that is based on this and have a handler on the GUI side of things reading the updates (maybe based on checking the FileInfo.Length property of the destination object using some type of timer?).</p>
<p>Does anyone know of a way to do this that I'm overlooking. If I can avoid it, I'd rather not rewrite my class to copy bytes through a stream and track it that way (though I'm thinking I might be stuck with going that route).</p>
<p>PS - I'm stuck with the .NET 2.0 framework for now, so any solution that requires features available in >= 3.0 only are not an option for me.</p>
<p>PPS - I'm open to solutions in any .NET language variety, not only c#.</p>

187,797 | <p>Say I've got a class like this:</p>
<pre><code>class Test
{
int x;
SomeClass s;
}
</code></pre>
<p>And I instantiate it like this:</p>
<pre><code>Test* t = new Test;
</code></pre>
<p>Is x on the stack, or the heap? What about s?</p>

187,799 | <p>Let me start by saying I'm a huge fan of the elegance of this pattern -- I have a group of basic entities that I have implemented builders for (specifically for testing). However I have found (and this may be the caveat) that as my program evolved I kept having to go back and re-work the builders. In the end, it really hasn't seemed worth it to keep them updated, and I've gone back to primarily keeping a Object Mother that has a lot of pre-configured entities. Should I continue to update the builders for future use, or is the TDBs something that should only be created once you're design has reached some stability and the Object Mother becomes too large?</p>
<p>Also note, I've found I'm not using the builders anywhere else in the app, as I enjoy using .Net 3.0 's new syntax for property initialization.</p>

187,804 | <p>I would like a "system" that monitors a process and would kill said process if:</p>
<ul>
<li>the process exceeds some memory requirements</li>
<li>the process does not respond to a message from the "system" in some period of time</li>
</ul>
<p>I assume this "system" could be something as simple as a monitoring process? A code example of how this could be done would be useful. I am of course not averse to a completely different solution to this problem.</p>

187,827 | <p>So for this one project, we have a bunch of queries that are executed on a regular basis (every minute or so. I used the "Analyze Query in Database Engine " to check on them. </p>
<p>They are pretty simple:
select * from tablex where processed='0'</p>
<p>There is an index on processed, and each query should return <1000 rows on a table with 1MM records.</p>
<p>The Analyzer recommended creating some STATISTICS on this.... So my question is: What are those statistics ? do they really help performance ? how costly are they for a table like above ? </p>
<p>Please bear in mind that by no means I would call myself a SQL Server experienced user ... And this is the first time using this Analyzer.</p>

187,849 | <p>I am experiencing some weird behavior with localized messages reported from my background worker process in my windows forms application.</p>
<p>The application is a setup application with windows forms.
The application launches a background worker to perform and IIS reset and then install MSIs.</p>
<p>The first time I run the application on a Spanish Win Server 2003 VM the forms are in spanish but not the BWP messages. If i immediately run it again, the messages are in spanish.</p>
<p>The .Resources files are embedded resources and are extracted to the temp directory upon application startup.</p>
<p>My code retrieves the localized strings through a custom resource manager class. This class creates a file based resource to the .Resources files in the temp directory. This is working correctly because the windows forms labels and title are localized every time.</p>
<p>Has anyone experienced this? I'm absolutely stuck, please help.
Thanks, Andrew</p>

187,851 | <p>How can I open a synchronous dialog in Flex? I need to call a function from an External Interface (JavaScript) that will open a simple dialog in the Flex application and returns an value according to the button the user has clicked (OK/Cancel).</p>
<p>So it should by a synchronous call to a dialog, i.e. the call waits until the user has closed the dialog like this.</p>
<pre><code>//This function is called by JavaScript
function onApplicationUnload():Boolean
{
var result:Boolean;
result = showDialogAndWaitForResult();
return result
}
</code></pre>
<p>Does anybody know how I can do this? I could write a loop that waits until the dialog has set a flag and then reads the result to return it, but there must be something that is way more elegant and reusable for waiting of the completion of other asynchronous calls.</p>
<p><strong>EDIT:</strong>
Unfortunately a callback does not work as the JavaScript function that calls onApplicationUnload() itself has to return a value (similar to the onApplicationUnload() function in Flex). This JavaScript function has a fixed signature as it is called by a framework and I cannot change it. Or in other words: The call from JavaScript to Flex must also be synchronous.</p>

187,857 | <p>We have a TIBCO EMS solution that uses built-in server failover in a 2-4 server environment. If the TIBCO admins fail-over services from one EMS server to another, connections are supposed to be transfered to the new server automatically at the EMS service level. For our C# applications using the EMS service, this is not happening - our user connections are not being transfered to the new server after failover and we're not sure why.</p>
<p>Our application connection to EMS at startup only so if the TIBCO admins failover after users have started our application, they users need to restart the app in order to reconnect to the new server (our EMS connection uses a server string including all 4 production EMS servers - if the first attempt fails, it moves to the next server in the string and tries again).</p>
<p>I'm looking for an automated approach that will attempt to reconnect to EMS periodically if it detects that the connection is dead but I'm not sure how best to do that.</p>
<p>Any ideas? We are using TIBCO.EMS.dll version 4.4.2 and .Net 2.x (SmartClient app)</p>
<p>Any help would be appreciated.</p>

<p>This all happens in the codebehind (VB.NET), where the code adds the placeholder and some controls inside tables (tables inside the placeholder).</p>
<p>I've added a button to this placeholder (inside a table cell), all programatically, but how can I add a click event to the button programatically? I want to fire a javascript (lightbox) which shows a large preview of the image (this works when the user clicks a small image, which invokes a string hyperlink on the code that points to the javascript).</p>

187,974 | <p>I have a simple Word to Pdf converter as an MSBuild Task. The task takes Word files (ITaskItems) as input and Pdf files (ITaskItems) as output. The script uses a Target transform for conversion:</p>
<pre><code><Project DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003" ToolsVersion="3.5">
<UsingTask AssemblyFile="$(MSBuildExtensionsPath)\MyTasks.dll" TaskName="MyTasks.DocToPdf" />
<Target Name="Build" DependsOnTargets="Convert" />
<Target Name="Convert"
Inputs="@(WordDocuments)"
Outputs="@(WordDocuments->'%(FileName).pdf')">
<DocToPdf Inputs="@(WordDocuments)"
Outputs="%(FileName).pdf">
<Output TaskParameter="ConvertedFiles" ItemName="PdfDocuments" />
</DocToPdf>
</Target>
<ItemGroup>
<WordDocuments Include="One.doc" />
<WordDocuments Include="SubDir\Two.doc" />
<WordDocuments Include="**\*.doc" />
</ItemGroup>
</Project>
</code></pre>
<p>What's happening is that SubDir\Two.doc gets converted on every incremental build, One.doc does not (ie MSBuild correctly skips that file because it was already converted). If I use the recursive items spec (the third one above), I get the same behaviour (ie. One.doc only gets converted if the PDF is out of date or missing, but all documents in subdirectories always get converted regardless).</p>
<p>What am I doing wrong here?</p>

187,990 | <p>I'm not a C++ developer, but I've always been interested in compilers, and I'm interested in tinkering with some of the GCC stuff (particularly LLVM).</p>
<p>On Windows, GCC requires a POSIX-emulation layer (cygwin or MinGW) to run correctly.</p>
<p>Why is that?</p>
<p>I use lots of other software, written in C++ and cross-compiled for different platforms (Subversion, Firefox, Apache, MySQL), and none of them require cygwin or MinGW.</p>
<p>My understanding about C++ best-practice programming is that you can write reasonably platform-neutral code and deal with all the differences during the compilation process.</p>
<p>So what's the deal with GCC? Why can't it run natively on Windows?</p>
<hr>
<p>EDIT:</p>
<p>Okay, the two replies so far say, basically, "GCC uses the posix layer because it uses the posix headers".</p>
<p>But that doesn't really answer the question.</p>
<p>Let's say I already have a set of headers for my favorite standard library. Why would I still need the posix headers?</p>
<p>Does GCC require cygwin/mingw to actually <em>RUN</em>?</p>
<p>Or does it only need the emulation layer for headers and libraries? If so, why can't I just give it a "lib" directory with the required resources?</p>
<hr>
<p>EDIT AGAIN:</p>
<p>Okay, I'll try again to clarify the question...</p>
<p>I also write code in <a href="http://digitalmars.com/d" rel="noreferrer">the D Programming Language</a>. The official compiler is named "dmd" and there are official compiler binaries for both Windows and linux.</p>
<p>The Windows version doesn't require any kind of POSIX emulation. And the Linux version doesn't require any kind of Win32 emulation. If the compiler has assumptions about its environment, it hides those assumptions pretty well.</p>
<p>Of course, I have to tell the compiler where to find the standard library and where to find libraries to statically or dynamically link against.</p>
<p>GCC, by contrast, insists on pretending it's operating within a posix environment, and it asks ME to humor those assumptions by setting up an emulation layer.</p>
<p>But what, exactly, within GCC relies on that layer? Is it just looking for stdlib headers, and it assumes it'll find those headers within "/usr/lib"?</p>
<p>If that's the case, shouldn't I just be able to tell it to look in "C:/gcc/lib" to find those header files?</p>
<p>Or does GCC itself rely on the POSIX libraries to access the file system (and to do other low-level stuff)? If that's the case, then I wonder why they don't just statically link with their favorite windows POSIX libraries. Why require the user to set up the dependencies, when they could build those dependencies right into the application?</p>

188,057 | <p>Quick question. What do you think, I have a few sites that use a 3 level drop-down menu that will be broken if IE8 released with its current CSS standards in IE8 beta2. So do I take the time to redo those drop downs now? I realize that the way they rendered CSS changed completely between beta 1 and 2, but 2 was/is supposed the be a general use beta and seeing as it is the final beta you would think something as crucial as CSS rendering would have been touched up to work properly.</p>
<p>So what do you think, do you wait until 80% (random statistic) of ie7 users automatically update to IE8 and then worry about a broken navigation menu if it still exists. Or do you waste the time now. </p>
<p>... if I had it my way all web developers would just make sure that their page did not work in IE8 and then Microsoft would be forced to properly handle CSS.... But I don't usually get things my way.</p>

188,098 | <p>I have a problem when an unhandeld exception occurs while debugging a WinForm VB.NET project.</p>
<p>The problem is that my application terminates and I have to start the application again, instead of retrying the action as was the case in VS2003</p>
<p>The unhandeld exception is implemented in the new My.MyApplication class found in ApplicationEvents.vb</p>
<pre><code>Private Sub MyApplication_UnhandledException(ByVal sender As Object, ByVal e As Microsoft.VisualBasic.ApplicationServices.UnhandledExceptionEventArgs) Handles Me.UnhandledException
Dim handler As New GlobalErrorHandler()
handler.HandleError(e.Exception)
e.ExitApplication = False
End Sub
</code></pre>
<p>Note: handler.HandleError just shows a dialog box and logs the error to a log file.</p>
<p>I also tried the following code that used to work in VS2003 but it results in the same behaviour when run in VS2008:</p>
<pre><code> AddHandler System.Windows.Forms.Application.ThreadException, AddressOf OnApplicationErrorHandler
AddHandler AppDomain.CurrentDomain.UnhandledException, AddressOf OnUnhandledExceptionHandler
</code></pre>
<p>OnApplicationErrorHandler and OnUnhandledExceptionHandler does the same as handle.HandleError</p>
<p>Running the application outside VS2008 results in the expected behaviour (the application doesn't terminate) but it is increasing our test cycle during debugging.</p>
<p><strong>Update:</strong> I have added sample code in my answer to demonstrate this problem in C#</p>

<p>I have given write access to the iis_iusrs, iis_wpg, and aspnet users, based on various advices found by Google, but still get the error.

188,120 | <p>So .NET 3.0/3.5 provides us with lots of new ways to query, sort, and manipulate data, thanks to all the neat functions supplied with LINQ. Sometimes, I need to compare user-defined types that don't have a built-in comparison operator. In many cases, the comparison is really simple -- something like foo1.key ?= foo2.key. Rather than creating a new IEqualityComparer for the type, can I simply specify the comparison inline using anonymous delegates/lambda functions? Something like:</p>
<pre><code>var f1 = ...,
f2 = ...;
var f3 = f1.Except(
f2, new IEqualityComparer(
(Foo a, Foo b) => a.key.CompareTo(b.key)
) );
</code></pre>
<p>I'm pretty sure the above doesn't actually work. I just don't want to have to make something as "heavy" as a whole class just to tell the program how to compare apples to apples.</p>

<p>The navigation is list, css'd so it looks like a bar. In order to highlight the page on the bar, the list item needs to look like this <code><li id="current"></code>. I do not want to use <code><asp:ContentPlaceHolder></code> if I can avoid it.

188,138 | <p>I've seen a number of references to gzipping a javascript to save download time. <em>But</em> I also see a number of warnings that certain browsers do not support this.</p>
<p>I have two different methods at my disposal:</p>
<ol>
<li>use <code>mod_deflate</code> to make Apache compress JS/CSS files in a given directory through htaccess</li>
<li>use <code>ob_start('gzhandler')</code> to compress a file and return it to the browser with the correct headers.</li>
</ol>
<p>The problems with method 1 are that not all browsers support mod_deflate, and I have no clue how to write the <code>.htaccess</code> file to be smart enough to adjust for this.</p>
<p>The problem with method 2 is that there is no definitive answer about how to tell if a browser supports a gzipped script, or stylesheet, and that if it does what mime-type must be given as the content type in the header.</p>
<p>I need some advice. First, which method is more universally accepted by browsers? Second, how do I decay using either method to provide the uncompressed backup script? Third, would <code><script src="js/lib.js.gz" type="text/javascript"></script></code> work by itself? (It obviously wouldn't decay.)</p>
<p>For the record, I'm using PHP5 with mod_deflate and full gzip creation capabilities, and my doctype is xhtml strict. Also, the javascript itself is compressed with YUI. <strong>Edit:</strong> I just went back and looked, but I have only Apache 1.3; I thought I had 2, so sorry for mentioning mod_deflate when I probably don't have it.</p>

188,208 | <p>There seem to be two bash idioms for redirecting STDOUT and STDERR to a file:</p>
<pre><code>fooscript &> foo
</code></pre>
<p>... and ...</p>
<pre><code>fooscript > foo 2>&1
</code></pre>
<p>What's the difference? It seems to me that the first one is just a shortcut for the second one, but my coworker contends that the second one will produce no output even if there's an error with the initial redirect, whereas the first one will spit redirect errors to STDOUT.</p>
<p><strong>EDIT</strong>: Okay... it seems like people are not understanding what I am asking, so I will try to clarify:</p>
<p>Can anyone give me an example where the two <em>specific lines</em> lines written above will yield different behavior?</p>

188,209 | <p>I have a page something.aspx, with associated codebehind something.aspx.cs. In that codebehind, I want to know the filesystem location of something.aspx. Is there any convenient way to get it?</p>
<p>Update: I got several excellent answers, which unfortunately didn't work because of something else crazy I'm doing. I'm encoding some additional information on the URL I pass in, so it looks like this:</p>
<p><a href="http://server/path/something.aspx/info1/info2/info3.xml" rel="nofollow noreferrer">http://server/path/something.aspx/info1/info2/info3.xml</a></p>
<p>The server deals with this OK (and I'm not using querystring parameters to work around some other code that I didn't write). But when I call Server.MapPath(Request.Url.ToString()) I get an error that the full URL with the 'info' segments isn't a valid virtual path.</p>

188,225 | <p>I use Visual C++ 2008 in Visual Studio 2008. I frequently use the following command to diff an open file against its most recent checked-in version:</p>
<pre><code>File | Source Control | Compare...
</code></pre>
<p>I can also do the same thing by clicking on an icon in the Source Control toolbar.</p>
<p>I'm not certain, but I believe this command is the same for any source control plugin (I happen to use the Perforce plugin.)</p>
<p>I'd like to assign a keyboard shortcut to execute this command but I can't seem to find it listed anywhere in dialog where such assignments are normally made:</p>
<pre><code>Tools | Customize... | Commands
</code></pre>
<p>Did I just not see the command in the customize dialog? Is there another method to assign such a keyboard shortcut?</p>

I get the "One or more selected items contain a data type that is not supported by the designer." error message. </p>
<p>I found that the spatial data type is the issue in this case. </p>
<p>My questions are:</p>
<ul>
<li>What other data types are not
inherently supported by Visual
Studio that is in SQL Serve 2008?</li>
<li>Why are these types not supported?</li>
</ul>
<p>The second question is I guess the most puzzling to me. I can understand why not all data types would be supported from MySQL, Oracle, Postgre SQL and so forth. I would think that the SQLServer development group, might give a heads up to the Visual Studio development group, you know yell down the hall or something. </p>

188,248 | <p>Does anyone have any info on creating/drawing a customised ListView object?</p>
<p>Currently Im working on a project that requires a customised look and feel within the application. I am using a standard (Windows.Forms) ListView which is not in the same style as the rest of the GUI. We are NOT using a toolbox for custom controls, all controlls are 'skinned' inhouse as it were by overriding hte OnPaint() method for each control.</p>
<p>What Im looking for is:
- Information about how to handle drawing of the Scroll Bar.
- How to use customised drawing routines to handle the column headers.
- How to still handle the data shown and draw that correctly.</p>
<p>Any and all help would be greatly received.</p>

188,281 | <p>In Delphi 2009 I'm finding that any time I use TThread.CurrentThread in an application, I'll get an error message like the following when the application closes:</p>
<pre><code>Exception EAccessViolation in module ntdll.dll at 0003DBBA.
Access violation at address 7799DBBA in module 'ntdll.dll'. Write of
address 00000014.
</code></pre>
<p>Unless it's just my machine, you can replicate this in a few seconds: create a new Delphi Forms Application, add a button to the form, and use something like the following for the button's event handler:</p>
<pre><code>procedure TForm1.Button1Click(Sender: TObject);
begin
TThread.CurrentThread;
end;
</code></pre>
<p>On both my Vista machine and my XP machine I'm finding that, if I <em>don't</em> click the button everything's fine, but if I <em>do</em> click the button I get the above error message when I close the application.</p>
<p>So... I'm wondering if this is a bug, but at the same time I think it's rather likely that I'm simply not understanding something very basic about how you're supposed to work with TThreads in Delphi. I am a bit of a Delphi newbie I'm afraid.</p>
<p>Is there something obviously wrong with using TThread.CurrentThread like that?</p>
<p>If not, and you have Delphi 2009, do you get the same problem if you implement my simple sample project?</p>

<h2><strong>Update: As François noted below, this actually is a bug in Delphi 2009 at the moment - you can <a href="http://qc.codegear.com/wc/qcmain.aspx?d=67726" rel="noreferrer">vote for it here</a>.</strong></h2>

188,299 | <p>I have the following struct in C++:</p>
<pre><code>#define MAXCHARS 15
typedef struct
{
char data[MAXCHARS];
int prob[MAXCHARS];
} LPRData;
</code></pre>
<p>And a function that I'm p/invoking into to get an array of 3 of these structures:</p>
<pre><code>void GetData(LPRData *data);
</code></pre>
<p>In C++ I would just do something like this:</p>
<pre><code>LPRData *Results;
Results = (LPRData *)malloc(MAXRESULTS*sizeof(LPRData));
GetData( Results );
</code></pre>
<p>And it would work just fine, but in C# I can't seem to get it to work.
I've created a C# struct like this:</p>
<pre><code>public struct LPRData
{
/// char[15]
[MarshalAsAttribute(UnmanagedType.ByValTStr, SizeConst = 15)]
public string data;
/// int[15]
[MarshalAsAttribute(UnmanagedType.ByValArray, SizeConst = 15)]
public int[] prob;
}
</code></pre>
<p>And if I initialize an array of 3 of those (and all their sub-arrays) and pass it into this:</p>
<pre><code>GetData(LPRData[] data);
</code></pre>
<p>It returns with success, but the data in the LPRData array has not changed.</p>
<p>I've even tried to create a raw byte array the size of 3 LPRData's and pass that into a function prototype like this:</p>
<p>GetData(byte[] data);</p>
<p>But in that case I will get the "data" string from the very first LPRData structure, but nothing after it, including the "prob" array from the same LPRData.</p>
<p>Any ideas of how to properly handle this?</p>

188,311 | <p>In a nutshell, the hashCode contract, according to Java's object.hashCode():</p>
<ol>
<li>The hash code shouldn't change unless something affecting equals() changes</li>
<li>equals() implies hash codes are ==</li>
</ol>
<p>Let's assume interest primarily in immutable data objects - their information never changes after they're constructed, so #1 is assumed to hold. That leaves #2: the problem is simply one of confirming that equals implies hash code ==.</p>
<p>Obviously, we can't test every conceivable data object unless that set is trivially small. So, what is the best way to write a unit test that is likely to catch the common cases?</p>
<p>Since the instances of this class are immutable, there are limited ways to construct such an object; this unit test should cover all of them if possible. Off the top of my head, the entry points are the constructors, deserialization, and constructors of subclasses (which should be reducible to the constructor call problem).</p>

188,349 | <p>I need to knock out a quick animation in C#/Windows Forms for a Halloween display. Just some 2D shapes moving about on a solid background. Since this is just a quick one-off project I <strong><em>really</em></strong> don't want to install and learn an entire new set of tools for this. (DirectX dev kits, Silverlight, Flash, etc..) I also have to install this on multiple computers so anything beyond the basic .Net framework (2.0) would be a pain in the arse.</p>
<p>For tools I've got VS2k8, 25 years of development experience, a wheelbarrow, holocaust cloak, and about 2 days to knock this out. I haven't done animation since using assembler on my Atari 130XE (hooray for page flipping and player/missile graphics!)</p>
<p>Advice? Here's some of the things I'd like to know:</p>
<ul>
<li>I can draw on any empty widget (like a panel) by fiddling with it's OnPaint handler, right? That's how I'd draw a custom widget. Is there a better technique than this?</li>
<li>Is there a page-flipping technique for this kind of thing in Windows Forms? I'm not looking for a high frame rate, just as little flicker/drawing as necessary.</li>
</ul>
<p>Thanks.</p>
<p><strong>Post Mortem Edit ... "a couple of coding days later"</strong></p>
<p>Well, the project is done. The links below came in handy although a couple of them were 404. (I wish SO would allow more than one reply to be marked "correct"). The biggest problem I had to overcome was flickering, and a persistent bug when I tried to draw on the form directly.</p>
<ul>
<li>Using the OnPaint event for the Form: bad idea. I never got that to work; lots of mysterious errors (stack overflows, or ArgumentNullExceptions). I wound up using a panel sized to fill the form and that worked fine.</li>
<li>Using the OnPaint method is slow anyway. Somewhere online I read that building the PaintEventArgs was slow, and they weren't kidding. Lots of flickering went away when I abandoned this. Skip the OnPaint/Invalidate() and just paint it yourself. </li>
<li><p>Setting all of the "double buffering" options on the form still left some flicker that had to be fixed. (And I found conflicting docs that said "set them on the control" and "set them on the form". Well controls don't have a .SetStyle() method.) I haven't tested without them, so they might be doing something (<code>this</code> is the form):</p>
<pre><code> this.SetStyle(ControlStyles.UserPaint, true);
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
</code></pre></li>
</ul>
<p>So the workhorse of the code wound up looking like (<code>pf</code> is the panel control):</p>
<pre><code> void PaintPlayField()
{
Bitmap bufl = new Bitmap(pf.Width, pf.Height);
using (Graphics g = Graphics.FromImage(bufl))
{
g.FillRectangle(Brushes.Black, new Rectangle(0, 0, pf.Width, pf.Height));
DrawItems(g);
DrawMoreItems(g);
pf.CreateGraphics().DrawImageUnscaled(bufl, 0, 0);
}
}
</code></pre>
<p>And I just called PaintPlayField from the inside of my Timer loop. No flicker at all.</p>

<p>Besides GUI development (see "<a href="https://stackoverflow.com/questions/174308/using-both-eclipse-and-netbeans">Using both Eclipse and Netbeans</a>"), are there any other issues with using both IDEs on the same system, or even the same project?</p>

188,389 | <p>I try to define a schema for XML documents I receive.</p>
<p>The documents look like:</p>
<pre><code><root>
<items>
<group name="G-1">
<item name="I-1"/>
<item name="I-2"/>
<item name="I-3"/>
<item name="I-4"/>
</group>
</items>
<data>
<group name="G-1" place="here">
<customer name="C-1">
<item name="I-1" count="3"/>
<item name="I-2" count="4"/>
</customer>
<customer name="C-2">
<item name="I-3" count="7"/>
</customer>
</group>
</data>
</root>
</code></pre>
<p>I tried XmlSpy and xsd.exe from .NET 2.0. Both created schema definitions which allow below <code><group></code> any number of <code><item></code> and <code><customer></code> elements. But what I'm looking for should restrict <code><group></code> below <code><items></code> to <code><item></code> elements, and <code><group></code> below <code><data></code> to <code><customer></code> elements.</p>
<p>Is this something xml schema is not capable at all?</p>

188,414 | <p>I have used the XML Parser before, and even though it worked OK, I wasn't happy with it in general, it felt like I was using workarounds for things that should be basic functionality.</p>
<p>I recently saw SimpleXML but I haven't tried it yet. Is it any simpler? What advantages and disadvantages do both have? Any other parsers you've used?</p>

188,422 | <p>How can I transform a website to be able to handle multi language (example : english, french, spanish)?</p>
<p>I do not like the resource file because I feel limited and it's pretty long to build the list. Do you have any suggestion?</p>
<h2>Update</h2>
<p>For the moment the best way we found is to use an XML file and with some Xpath et get values.</p>

188,425 | <p>I have been trying to work my way through Project Euler, and have noticed a handful of problems ask for you to determine a prime number as part of it.</p>
<ol>
<li><p>I know I can just divide x by 2, 3, 4, 5, ..., square root of X and if I get to the square root, I can (safely) assume that the number is prime. Unfortunately this solution seems quite klunky.</p></li>
<li><p>I've looked into better algorithms on how to determine if a number is prime, but get confused fast.</p></li>
</ol>
<p>Is there a simple algorithm that can determine if X is prime, and not confuse a mere mortal programmer?</p>
<p>Thanks much!</p>
