7,694 | <p>Is this even a valid question? I have a .NET Windows app that is using MSTDC and it is throwing an exception:</p>
<blockquote>
<p>System.Transactions.TransactionManagerCommunicationException: Network access for Distributed Transaction Manager (MSDTC) has been disabled. Please enable DTC for
network access in the security configuration for MSDTC using the Component Services Administrative tool ---> System.Runtime.InteropServices.COMException (0x8004D024): The transaction manager has disabled its support for remote/network
transactions. (Exception from HRESULT: 0x8004D024) at System.Transactions.Oletx.IDtcProxyShimFactory.ReceiveTransaction(UInt32
propgationTokenSize, Byte[] propgationToken, IntPtr managedIdentifier,
Guid& transactionIdentifier, OletxTransactionIsolationLevel&
isolationLevel, ITransactionShim& transactionShim)....</p>
</blockquote>
<p>I followed <a href="https://support.microsoft.com/en-us/kb/883960" rel="noreferrer">the Kbalertz guide to enable MSDTC</a> on the PC on which the app is installed, but the error still occurs. </p>
<p>I was wondering if this was a database issue? If so, how can I resolve it?</p>

7,707 | <p>I have an element which may contain very big amounts of data, but I don't want it to ruin the page layout, so I set <code>max-height: 100px</code> and <code>overflow:auto</code>, hoping for scrollbars to appear when the content does not fit. </p>
<p>It all works fine in Firefox and IE7, but IE8 behaves as if <code>overflow:hidden</code> was present instead of <code>overflow:auto</code>. </p>
<p>I tried <code>overflow:scroll</code>, still does not help, IE8 simply truncates the content without showing scrollbars. Changing <code>max-height</code> declaration to <code>height</code> makes overflow work OK, it's the combination of <code>max-height</code> and <code>overflow:auto</code> that breaks things.</p>
<p>This is also logged as an <a href="http://connect.microsoft.com/IE/feedback/ViewFeedback.aspx?FeedbackID=408759" rel="noreferrer">official bug in the final, release version of IE8</a></p>
<p>Is there a workaround? For now I resorted to using <code>height</code> instead of <code>max-height</code>, but it leaves plenty of empty space in case there isn't much data.</p>

7,719 | <p>Is there any way to capture the MouseDown even from the .NET 2.0 TextBox control?
I know the inherited Control class has the event, but it's not exposed in TextBox.
Is there a way to override the event handler?</p>
<p>I also tried the OpenNETCF TextBox2 control which does have the MouseDown event exposed, but no matter what I do, it doesn't fire the handler.</p>
<p>Any suggestions?</p>
<hr>
<blockquote>
<p>What kind of crazy mobile device do
you have that has a mouse? :)</p>
</blockquote>
<p>Yes, windows mobile does not have an actual mouse, but you are mistaken that Windows Mobile .NET do not support the Mouse events. A click or move on the screen is still considered a "Mouse" event. It was done this way so that code could port over from full Windows easily. And this is not a Windows Mobile specific issue. The TextBox control on Windows does not have native mouse events either. I just happened to be using Windows Mobile in this case.</p>
<p>Edit: And on a side note...as Windows Mobile is built of the WindowsCE core which is often used for embedded desktop systems and Slim Terminal Services clients or "WinTerms" it has support for a hardware mouse and has for a long time. Most devices just don't have the ports to plug one in.</p>
<hr>
<blockquote>
<p>According to the .Net Framework, the
MouseDown Event Handler on a TextBox
is supported. What happens when you
try to run the code?</p>
</blockquote>
<p>Actually, that's only there because it inherits it from "Control", as does <em>every</em> other Form control. It is, however, overridden (and changed to private I believe) in the TextBox class. So it will not show up in IntelliSense in Visual Studio.</p>
<p>However, you actually can write the code:</p>
<pre><code>textBox1.MouseDown += new System.Windows.Forms.MouseEventHandler(this.textBox1_MouseDown);
</code></pre>
<p>and it will compile and run just fine, the only problem is that textBox1_MouseDown() will not be fired when you tap the TextBox control. I assume this is because of the Event being overridden internally. I don't even want to change what's happening on the event internally, I just want to add my own event handler to that event so I can fire some custom code as you could with any other event.</p>

7,720 | <p>I am writing an application in Java for the desktop using the Eclipse SWT library for GUI rendering. I think SWT helps Java get over the biggest hurdle for acceptance on the desktop: namely providing a Java application with a consistent, responsive interface that looks like that belonging to any other app on your desktop. However, I feel that packaging an application is still an issue. </p>
<p>OS X natively provides an easy mechanism for wrapping Java apps in native application bundles, but producing an app for Windows/Linux that doesn't require the user to run an ugly batch file or click on a .jar is still a hassle. Possibly that's not such an issue on Linux, where the user is likely to be a little more tech-savvy, but on Windows I'd like to have a regular .exe for him/her to run.</p>
<p>Has anyone had any experience with any of the .exe generation tools for Java that are out there? I've tried JSmooth but had various issues with it. Is there a better solution before I crack out Visual Studio and roll my own?</p>
<p><strong>Edit:</strong> I should perhaps mention that I am unable to spend a lot of money on a commercial solution.</p>

7,737 | <p>Is there a good way for displaying unicode text in opengl under Windows? For example, when you have to deal with different languages. The most common approach like</p>
<pre><code>#define FONTLISTRANGE 128
GLuint list;
list = glGenLists(FONTLISTRANGE);
wglUseFontBitmapsW(hDC, 0, FONTLISTRANGE, list);
</code></pre>
<p>just won't do because you can't create enough lists for all unicode characters.</p>

7,758 | <p>I'm getting all learned up about binding in WPF. I'm having a lot of trouble debugging the parse errors in my xaml, though. Can somebody pretty please tell me what's wrong with this little piece? :</p>
<pre><code><Border Name="TrackBackground"
Margin="0"
CornerRadius="2"
Grid.Row="1"
Grid.Column="1"
Background="BlanchedAlmond"
BorderThickness="1"
Height="{TemplateBinding Height}">
<Canvas Name="PART_Track" Background="DarkSalmon" Grid.Row="1" Grid.Column="1">
<Thumb Name="ThumbKnob" Height="{Binding ElementName=Part_Track, Path=Height, Mode=OneWay}" />
</Canvas>
</Border>
</code></pre>
<p>It's the databinding that breaks. I get an <code>InvalidAttributeValue</code> exception for ThumbKnob.Height when I try to run this. I know I must be missing something fundamental. So fill me in, stackers, and my gratitude will be boundless.</p>
<hr>
<p>Changing the ElementName didn't help. There must me something else I'm not getting.</p>
<p>I should mention that I'm testing this in Silverlight. The exact message I'm getting out of Internet Explorer is:</p>
<p><code>XamlParseException: Invalid attribute value for property Height.</code></p>
<p>This whole thing is inside a ControlTemplate. I'm making a slider control just to teach myself the concepts.</p>

7,846 | <p>I would like to use a language that I am familiar with - Java, C#, Ruby, PHP, C/C++, although examples in any language or pseudocode are more than welcome.</p>
<p>What is the best way of splitting a large XML document into smaller sections that are still valid XML? For my purposes, I need to split them into roughly thirds or fourths, but for the sake of providing examples, splitting them into n components would be good.</p>

<p>By default, Safe Mode does a UID compare check when opening files. If you want to relax this to a GID compare, then turn on safe_mode_gid. Whether to use UID (FALSE) or GID (TRUE) checking upon file access.</p>

7,864 | <p>As I learn more and more about OOP, and start to implement various design patterns, I keep coming back to cases where people are hating on <a href="http://en.wikipedia.org/wiki/Active_record_pattern" rel="noreferrer">Active Record</a>.</p>
<p>Often, people say that it doesn't scale well (citing Twitter as their prime example) -- but nobody actually explains <strong><em>why</em></strong> it doesn't scale well; and / or how to achieve the pros of AR without the cons (via a similar but different pattern?)</p>
<p>Hopefully this won't turn into a holy war about design patterns -- all I want to know is ****specifically**** what's wrong with Active Record.</p>
<p>If it doesn't scale well, why not?</p>
<p>What other problems does it have?</p>

7,884 | <p>I've just come across this in a WHERE clause:</p>
<pre><code>AND NOT (t.id = @id)
</code></pre>
<p>How does this compare with:</p>
<pre><code>AND t.id != @id
</code></pre>
<p>Or with:</p>
<pre><code>AND t.id <> @id
</code></pre>
<p>I'd always write the latter myself, but clearly someone else thinks differently. Is one going to perform any better than the other? I know that using <code><></code> or <code>!=</code> is going to bust any hopes for using an index that I might have had, but <em>surely</em> the first approach above will suffer the same problem?</p>

7,937 | <p>When using IE, you cannot put an absolutely positioned div over a select input element. That's because the select element is considered an ActiveX object and is on top of every HTML element in the page.</p>
<p>I already saw people hiding selects when opening a popup div, that leads to pretty bad user experience having controls disappearing.</p>
<p>FogBugz actually had a pretty smart solution (before v6) of turning every select into text boxes when a popup was displayed. This solved the bug and tricked the user eye but the behavior was not perfect.</p>
<p>Another solution is in FogBugz 6 where they no more use the select element and recoded it everywhere.</p>
<p>Last solution I currently use is messing up the IE rendering engine and force it to render the absolutely positioned <code><div></code> as an ActiveX element too, ensuring it can live over a select element. This is achieved by placing an invisible <code><iframe></code> inside the <code><div></code> and styling it with:</p>
<pre class="lang-css prettyprint-override"><code>#MyDiv iframe
{
position: absolute;
z-index: -1;
filter: mask();
border: 0;
margin: 0;
padding: 0;
top: 0;
left: 0;
width: 9999px;
height: 9999px;
overflow: hidden;
}
</code></pre>
<p>Does anyone have an even better solution than this one?</p>
<p>EDIT: The purpose of this question is as much informative as it is a real question. I find the <code><iframe></code> trick to be a good solution, but I am still looking for improvement like removing this <em>ugly useless tag</em> that degrades accessibility.</p>

7,981 | <p>I'm working on bringing some old code from 1998 up to the 21st century. One of the first steps in the process is converting the printf statements to <a href="http://qt-project.org/doc/qt-4.8/qstring.html" rel="nofollow noreferrer">QString</a> variables. No matter how many times I look back at printf though, I always end up forgetting one thing or the other. So, for fun, let's decode it together, for ole' times sake and in the process create the first little <strong>'printf primer'</strong> for Stackoverflow.</p>
<p>In the code, I came across this little gem,</p>
<pre><code>printf("%4u\t%016.1f\t%04X\t%02X\t%1c\t%1c\t%4s", a, b, c, d, e, f, g);
</code></pre>
<p>How will the variables a, b, c, d, e, f, g be formatted?</p>

7,991 | <p>I'm using the .NETCF (Windows Mobile) <code>Graphics</code> class and the <code>DrawString()</code> method to render a single character to the screen.</p>
<p>The problem is that I can't seem to get it centred properly. No matter what I set for the Y coordinate of the location of the string render, it always comes out lower than that and the larger the text size the greater the Y offset.</p>
<p>For example, at text size 12, the offset is about 4, but at 32 the offset is about 10.</p>
<p>I want the character to vertically take up most of the rectangle it's being drawn in and be centred horizontally. Here's my basic code. <code>this</code> is referencing the user control it's being drawn in.</p>
<pre><code>Graphics g = this.CreateGraphics();
float padx = ((float)this.Size.Width) * (0.05F);
float pady = ((float)this.Size.Height) * (0.05F);
float width = ((float)this.Size.Width) - 2 * padx;
float height = ((float)this.Size.Height) - 2 * pady;
float emSize = height;
g.DrawString(letter, new Font(FontFamily.GenericSansSerif, emSize, FontStyle.Regular),
new SolidBrush(Color.Black), padx, pady);
</code></pre>
<p>Yes, I know there is the label control that I could use instead and set the centring with that, but I actually do need to do this manually with the <code>Graphics</code> class.</p>

8,004 | <p>I use <a href="http://rsync.samba.org/" rel="nofollow noreferrer">rsync</a> to synchronize files to Windows clients in a server agnostic way. What methods are available to send the progress of rsync to the parent process for display in a gui progress bar?</p>
<p>I imagine two or three choices exist. (1) Watch STDOUT (2) Watch rsync.exe log file, similar to unix <code>tail</code> (3) Watch rsync console output in memory.</p>
<p>Which one is best/preferred?</p>

8,042 | <p>The new extensions in .Net 3.5 allow functionality to be split out from interfaces.</p>
<p>For instance in .Net 2.0</p>
<pre><code>public interface IHaveChildren {
string ParentType { get; }
int ParentId { get; }
List<IChild> GetChildren()
}
</code></pre>
<p>Can (in 3.5) become:</p>
<pre><code>public interface IHaveChildren {
string ParentType { get; }
int ParentId { get; }
}
public static class HaveChildrenExtension {
public static List<IChild> GetChildren( this IHaveChildren ) {
//logic to get children by parent type and id
//shared for all classes implementing IHaveChildren
}
}
</code></pre>
<p>This seems to me to be a better mechanism for many interfaces. They no longer need an abstract base to share this code, and functionally the code works the same. This could make the code more maintainable and easier to test.</p>
<p>The only disadvantage being that an abstract bases implementation can be virtual, but can that be worked around (would an instance method hide an extension method with the same name? would it be confusing code to do so?)</p>
<p>Any other reasons not to regularly use this pattern?</p>
<hr>
<p>Clarification:</p>
<p>Yeah, I see the tendency with extension methods is to end up with them everywhere. I'd be particularly careful having any on .Net value types without a great deal of peer review (I think the only one we have on a string is a <code>.SplitToDictionary()</code> - similar to <code>.Split()</code> but taking a key-value delimiter too)</p>
<p>I think there's a whole best practice debate there ;-)</p>
<p>(Incidentally: DannySmurf, your PM sounds scary.)</p>
<p>I'm specifically asking here about using extension methods where previously we had interface methods.</p>
<hr>
<p>I'm trying to avoid lots of levels of abstract base classes - the classes implementing these models mostly already have base classes. I think this model could be more maintainable and less overly-coupled than adding further object hierarchies.</p>
<p>Is this what MS has done to IEnumerable and IQueryable for Linq?</p>

8,107 | <p>When I have two mysql servers that have different jobs (holding different databases) but want to be able to use one of them to slip in when the other one fails, what would you suggest how I keep the data on both of them equal "close to realtime"? </p>
<p>Obviously it's not possible to make a full database dump every x minutes.</p>
<p>I've read about the <a href="http://dev.mysql.com/doc/refman/5.0/en/binary-log.html" rel="noreferrer">Binary Log</a>, is that the way that I need to go? Will that not slow down the fallback server a lot? Is there a way to not include some tables in the binary log - where it doesn't matter that the data has changed?</p>

8,140 | <p>Is there a general procedure for programming extensibility capability into your code?</p>
<p>I am wondering what the general procedure is for adding extension-type capability to a system you are writing so that functionality can be extended through some kind of plugin API rather than having to modify the core code of a system.</p>
<p>Do such things tend to be dependent on the language the system was written in, or is there a general method for allowing for this?</p>

8,147 | <p>Using <a href="http://www.codeplex.com/aspnet" rel="nofollow noreferrer">preview 4</a> of <a href="http://asp.net/mvc" rel="nofollow noreferrer">ASP.NET MVC</a>
Code like:</p>
<pre><code><%= Html.CheckBox( "myCheckBox", "Click Here", "True", false ) %>
</code></pre>
<p>only outputs:</p>
<pre><code><input type="checkbox" value="True" name="myCheckBox" />
</code></pre>
<p>There is a <code>name</code> there for the form post back but no <code>id</code> for javascript or labels :-(</p>
<p>I was hoping that changing it to:</p>
<pre><code>Html.CheckBox( "myCheckBox", "Click Here",
"True", false, new { id="myCheckBox" } )
</code></pre>
<p>would work - but instead I get an exception:</p>
<pre><code>System.ArgumentException: An item with the same key has already been added.
</code></pre>
<p>As if there was already an id somewhere in a collection somewhere - I'm stumped!</p>

8,154 | <p>I'm using Pylons (a python framework) to serve a simple web application, but it seems to die from time to time, with this in the error log: <code>(2006, 'MySQL server has gone away')</code></p>
<p>I did a bit of checking, and saw that this was because the connections to MySQL were not being renewed. This shouldn't be a problem though, because the <code>sqlalchemy.pool_recycle</code> in the config file should automatically keep it alive. The default was <code>3600</code>, but I dialed it back to <code>1800</code> because of this problem. It helped a bit, but <code>3600</code> <em>should</em> be fine according to the docs. The errors still happen semi-regularly. I don't want to lower it too much though and DOS my own database :).</p>
<p>Maybe something in my MySQL config is goofy? Not sure where to look exactly.</p>
<p>Other relevant details:</p>
<pre><code> Python 2.5
Pylons: 0.9.6.2 (w/ sql_alchemy)
MySQL: 5.0.51
</code></pre>

8,213 | <p>I need to import a csv file into <strong>Firebird</strong> and I've spent a couple of hours trying out some tools and none fit my needs.</p>
<p>The main problem is that all the tools I've been trying like <a href="http://www.sqlmanager.net/products/ibfb/dataimport" rel="noreferrer">EMS Data Import</a> and <a href="http://www.sqlmaestro.com/products/firebird/datawizard/help/06_01_05_csv/" rel="noreferrer">Firebird Data Wizard</a> expect that my CSV file contains all the information needed by my Table.</p>
<p>I need to write some custom SQL in the insert statement, for example, I have a CSV file with the city name, but as my database already has all the cities in another table (normalized), I need to write a subselect in the insert statement to lookup for the city and write its ID, also I have a stored procedure to cread GUIDS.</p>
<p>My insert statement would be something like this:</p>
<pre><code>INSERT INTO PERSON (ID, NAME, CITY_ID) VALUES((SELECT NEW_GUID FROM CREATE_GUID), :NAME, (SELECT CITY_ID FROM CITY WHERE NAME = :CITY_NAME)
</code></pre>
<p>How can I approach this?</p>

8,214 | <p>How are you instrumenting your UI's? In the past I've read that people have instrumented their user interfaces, but what I haven't found is examples or tips on <em>how</em> to instrument a UI.</p>
<p>By instrumenting, I mean collecting data regarding usage and performance of the system. A MSDN article on Instrumentation is <a href="http://msdn.microsoft.com/en-us/library/x5952w0c.aspx" rel="nofollow noreferrer" title="here">http://msdn.microsoft.com/en-us/library/x5952w0c.aspx</a>. I would like to capture which buttons users click on, what keyboard shortucts they use, what terms they use to search, etc.</p>
<ul>
<li>How are you instrumenting your UI?</li>
<li>What format are you storing the instrumentation?</li>
<li>How are you processing the instrumented data?</li>
<li>How are you keeping your UI code clean with this instrumentation logic?</li>
</ul>
<p>Specifically, I am implementing my UI in WPF, so this will provide extra challenges compared to instrumenting a web-based application. (i.e. need to transfer the instrumented data back to a central location, etc). That said, I feel the technology may provide an easier implementation of instrumentation via concepts like attached properties.</p>
<ul>
<li>Have you instrumented a WPF application? Do you have any tips on how this can be achieved?</li>
</ul>
<hr />
<p>Edit: The following blog post presents an interesting solution: <a href="https://blog.pixelingene.com/2008/08/techniques-for-ui-auditing-on-wpf-apps/" rel="nofollow noreferrer">Pixel-In-Gene Blog: Techniques for UI Auditing on WPF apps</a></p>

8,284 | <p>I'm looking for an online solution for generating .ICO files. I'd like the ICO files to have the ability to have transparency as well.</p>
<p>What software or web site do you use to create them?</p>
<p>[Update]</p>
<p>To clarify, I have an existing image in PNG format, 32 x 32 pixels. I want to generate the icon from this existing file, not create a brand new one online. Sorry for the confusion.</p>

8,348 | <p>Imagine an object you are working with has a collection of other objects associated with it, for example, the Controls collection on a WinForm. You want to check for a certain object in the collection, but the collection doesn't have a <code>Contains()</code> method. There are several ways of dealing with this.</p>
<ul>
<li>Implement your own <code>Contains()</code> method by looping through all items in the collection to see if one of them is what you are looking for. This seems to be the "best practice" approach.</li>
<li>I recently came across some code where instead of a loop, there was an attempt to access the object inside a try statement, as follows:</li>
</ul>
<blockquote>
<pre><code>try
{
Object aObject = myCollection[myObject];
}
catch(Exception e)
{
//if this is thrown, then the object doesn't exist in the collection
}
</code></pre>
</blockquote>
<p>My question is how poor of a programming practice do you consider the second option be and why? How is the performance of it compared to a loop through the collection?</p>

8,355 | <p>What is the best way to transparently rewrite a URL over an SSL connection with Apache 2.2?</p>
<p>Apache 2 does not natively support multiple name-based virtual hosts for an SSL connection and I have heard that mod_rewrite can help with this. I would like to do something like this:</p>
<p>I have set up the server so that the sites can be accessed by</p>
<p><a href="https://secure.example.com/dbadmin" rel="nofollow noreferrer">https://secure.example.com/dbadmin</a></p>
<p>but I would like to have this as <a href="https://dbadmin.example.com" rel="nofollow noreferrer">https://dbadmin.example.com</a></p>
<p>How do I set it up so that the Rewrite rule will rewrite dbadmin.example.com to secure.example.com/dbadmin, but without displaying the rewrite on the client's address bar (i.e. the client will still just see dbadmin.example.com), all over https?</p>

8,371 | <p>How do you redirect HTTPS to HTTP?. That is, the opposite of what (seemingly) everyone teaches.</p>
<p>I have a server on HTTPS for which I paid an SSL certification for and a mirror for which I haven't and keep around for just for emergencies so it doesn't merit getting a certification for.</p>
<p>On my client's desktops I have SOME shortcuts which point to <code>http://production_server</code> and <code>https://production_server</code> (both work). However, I know that if my production server goes down, then DNS forwarding kicks in and those clients which have "https" on their shortcut will be staring at <code>https://mirror_server</code> (which doesn't work) and a big fat Internet Explorer 7 red screen of uneasyness for my company. </p>
<p>Unfortunately, I can't just switch this around at the client level. These users are very computer illiterate: and are very likely to freak out from seeing HTTPS "insecurity" errors (especially the way Firefox 3 and Internet Explorer 7 handle it nowadays: FULL STOP, kind of thankfully, but not helping me here LOL).</p>
<p>It's <a href="http://www.cyberciti.biz/tips/howto-apache-force-https-secure-connections.html" rel="noreferrer">very easy</a> <a href="http://bytes.com/forum/thread54801.html" rel="noreferrer">to find</a> <a href="http://support.jodohost.com/showthread.php?t=6678" rel="noreferrer">Apache solutions</a> for <a href="http://www.google.com/search?q=https+redirection&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a" rel="noreferrer">http->https redirection</a>, but for the life of me I can't do the opposite.</p>
<p>Ideas?</p>

8,447 | <p>From time to time I see an enum like the following:</p>
<pre><code>[Flags]
public enum Options
{
None = 0,
Option1 = 1,
Option2 = 2,
Option3 = 4,
Option4 = 8
}
</code></pre>
<p>I don't understand what exactly the <code>[Flags]</code> attribute does.</p>
<p>Anyone have a good explanation or example they could post?</p>

8,451 | <p>I want to create an allocator which provides memory with the following attributes:</p>
<ul>
<li>cannot be paged to disk. </li>
<li>is incredibly hard to access through an attached debugger</li>
</ul>
<p>The idea is that this will contain sensitive information (like licence information) which should be inaccessible to the user. I have done the usual research online and asked a few other people about this, but I cannot find a good place start on this problem.</p>
<p><strong>Updates</strong></p>
<p><a href="https://stackoverflow.com/questions/8451/secure-memory-allocator-in-c#27194">Josh</a> mentions using <code>VirtualAlloc</code> to set protection on the memory space. I have created a custom allocator ( shown below ) I have found the using the <code>VirtualLock</code> function it limits the amount of memory I can allocate. This seems to be by design though. Since I am using it for small objects this is not a problem.</p>
<pre><code>//
template<class _Ty>
class LockedVirtualMemAllocator : public std::allocator<_Ty>
{
public:
template<class _Other>
LockedVirtualMemAllocator<_Ty>& operator=(const LockedVirtualMemAllocator<_Other>&)
{ // assign from a related LockedVirtualMemAllocator (do nothing)
return (*this);
}
template<class Other>
struct rebind {
typedef LockedVirtualMemAllocator<Other> other;
};
pointer allocate( size_type _n )
{
SIZE_T allocLen = (_n * sizeof(_Ty));
DWORD allocType = MEM_COMMIT;
DWORD allocProtect = PAGE_READWRITE;
LPVOID pMem = ::VirtualAlloc( NULL, allocLen, allocType, allocProtect );
if ( pMem != NULL ) {
::VirtualLock( pMem, allocLen );
}
return reinterpret_cast<pointer>( pMem );
}
pointer allocate( size_type _n, const void* )
{
return allocate( _n );
}
void deallocate(void* _pPtr, size_type _n )
{
if ( _pPtr != NULL ) {
SIZE_T allocLen = (_n * sizeof(_Ty));
::SecureZeroMemory( _pPtr, allocLen );
::VirtualUnlock( _pPtr, allocLen );
::VirtualFree( _pPtr, 0, MEM_RELEASE );
}
}
};
</code></pre>
<p>and is used</p>
<pre><code> //a memory safe std::string
typedef std::basic_string<char, std::char_traits<char>,
LockedVirtualMemAllocato<char> > modulestring_t;
</code></pre>
<p><a href="https://stackoverflow.com/questions/8451/secure-memory-allocator-in-c#38708">Ted Percival</a> mentions mlock, but I have no implementation of that yet.</p>
<p>I found <a href="http://www.schneier.com/book-practical.html" rel="noreferrer">Practical Cryptography by Neil Furguson and Bruce Schneier</a> quite helpful as well.</p>

8,472 | <p>It looks like we'll be adding <a href="http://en.wikipedia.org/wiki/Captcha" rel="noreferrer">CAPTCHA</a> support to Stack Overflow. This is necessary to prevent bots, spammers, and other malicious scripted activity. We only want human beings to post or edit things here!</p>
<p>We'll be using a JavaScript (jQuery) CAPTCHA as a first line of defense:</p>
<p><a href="http://docs.jquery.com/Tutorials:Safer_Contact_Forms_Without_CAPTCHAs" rel="noreferrer">http://docs.jquery.com/Tutorials:Safer_Contact_Forms_Without_CAPTCHAs</a></p>
<p>The advantage of this approach is that, <strong>for most people, the CAPTCHA won't ever be visible!</strong></p>
<p>However, for people with JavaScript disabled, we still need a fallback and this is where it gets tricky.</p>
<p>I have written a <a href="http://www.codeproject.com/KB/custom-controls/CaptchaControl.aspx" rel="noreferrer">traditional CAPTCHA control for ASP.NET</a> which we can re-use.</p>
<p><img src="https://i.stack.imgur.com/Puvbf.jpg" alt="CaptchaImage"></p>
<p>However, I'd prefer to go with something textual to avoid the overhead of creating all these images on the server with each request.</p>
<p>I've seen things like..</p>
<ul>
<li>ASCII text captcha: <code>\/\/(_)\/\/</code></li>
<li>math puzzles: what is 7 minus 3 times 2?</li>

8,485 | <p>I'm using ASP.NET MVC Preview 4 and would like to know how to use the routing engine for form submissions.</p>
<p>For example, I have a route like this:</p>
<pre><code>routes.MapRoute(
"TestController-TestAction",
"TestController.mvc/TestAction/{paramName}",
new { controller = "TestController", action = "TestAction", id = "TestTopic" }
);
</code></pre>
<p>And a form declaration that looks like this:</p>
<pre><code><% using (Html.Form("TestController", "TestAction", FormMethod.Get))
{ %>
<input type="text" name="paramName" />
<input type="submit" />
<% } %>
</code></pre>
<p>which renders to:</p>
<pre><code><form method="get" action="/TestController.mvc/TestAction">
<input type="text" name="paramName" />
<input type="submit" />
</form>
</code></pre>
<p>The resulting URL of a form submission is:</p>
<pre><code>localhost/TestController.mvc/TestAction?paramName=value
</code></pre>
<p>Is there any way to have this form submission route to the desired URL of:</p>
<pre><code>localhost/TestController.mvc/TestAction/value
</code></pre>
<p>The only solutions I can think of are to create a separate action that just checks the request parameters, or to use Javascript.</p>

8,496 | <p>I've moved from TFS to SVN (TortoiseSVN) with my current company. I really miss the "Shelve" feature of TFS. I've read various articles on how to "Shelve" with SVN, but I've read nothing that gives a very simple experience to "shelve" work.</p>
<p>Ideally, I'd like extra items added to the TortoiseSVN context menu - "Shelve" & "Unshelve".
"Shelve" would remove the current shelve-set, and upload the working directory under a suitable path defined by user options. "Unshelve" would merge the set with the working copy.</p>
<p>Does something like this exist? Can anyone suggest any ways to "hack" this feature in the GUI?</p>
<p>Note: The following link doesn't really achieve the user experience I was looking for:</p>
<p><a href="http://mikemason.ca/2005/03/30/" rel="noreferrer">Shelving Subversion</a></p>
<p>One of the greatest things about TFS Shelve is how easy it is to use...</p>

8,532 | <p>I've had an app doing prefix searches for a while. Recently the index size was increased and it turned out that some prefixes were too darned numerous for lucene to handle. It kept throwing me a <a href="http://web.archive.org/web/20080901205009/http://lucene.apache.org:80/java/2_3_2/api/core/org/apache/lucene/search/BooleanQuery.TooManyClauses.html" rel="nofollow noreferrer">Too Many Clauses</a> error, which was very frustrating as I kept looking at my JARs and confirming that none of the included code actually used a boolean query.</p>
<p>Why doesn't it throw something like a Too Many Hits exception? And why does increasing the boolean query's static max clauses integer actually make this error go away, when I'm definitely only using a prefix query? Is there something fundamental to how queries are run that I'm not understanding; is it that they secretly become Boolean queries?</p>

8,549 | <p>Is there any Visual Studio Add-In that can do the remove method refactoring?<br>
Suppose you have the following method: </p>
<pre><code>Result DoSomething(parameters)
{
return ComputeResult(parameters);
}
</code></pre>
<p>Or the variant where Result is void.</p>
<p>The purpose of the refactoring is to replace all the calls to DoSomething with calls to ComputeResult or the expression that uses the parameters if ComputeResult is not a method call.</p>

8,566 | <p>First off, this is a question about a desktop application using Windows Forms, not an <a href="http://en.wikipedia.org/wiki/ASP.NET" rel="nofollow noreferrer">ASP.NET</a> question.</p>
<p>I need to interact with controls on other forms. I am trying to access the controls by using, for example, the following...</p>
<pre><code>otherForm.Controls["nameOfControl"].Visible = false;
</code></pre>
<p>It doesn't work the way I would expect. I end up with an exception thrown from <code>Main</code>. However, if I make the controls <code>public</code> instead of <code>private</code>, I can then access them directly, as so...</p>
<pre><code>otherForm.nameOfControl.Visible = false;
</code></pre>
<p>But is that the best way to do it? Is making the controls <code>public</code> on the other form considered "best practice"? Is there a "better" way to access controls on another form?</p>
<p><strong>Further Explanation:</strong></p>
<p>This is actually a sort of follow-up to another question I asked, <em><a href="https://stackoverflow.com/questions/3725/best-method-for-creating-a-tree-view-preferences-dialog-type-of-interface-in-c">Best method for creating a “tree-view preferences dialog” type of interface in C#?</a></em>. The answer I got was great and solved many, many organizational problems I was having in terms of keeping the UI straight and easy to work with both in run-time and design-time. However, it did bring up this one niggling issue of easily controlling other aspects of the interface.</p>
<p>Basically, I have a root form that instantiates a lot of other forms that sit in a panel on the root form. So, for instance, a radio button on one of those sub-forms might need to alter the state of a status strip icon on the main, root form. In that case, I need the sub-form to talk to the control in the status strip of the parent (root) form. (I hope that makes sense, not in a "who's on first" kind of way.)</p>

8,599 | <p>Can anyone recommend a good binary XML format? It's for a JavaME application, so it needs to be a) Easy to implement on the server, and b) Easy to write a low-footprint parser for on a low-end JavaME client device.</p>
<p>And it goes without saying that it needs to be smaller than XML, and faster to parse.</p>
<hr>
<p>The data would be something akin to SVG.</p>

8,604 | <p>We are looking for a WYSIWYG editor control for our windows application (vb.net or c#) so that users can design HTML emails (to send using the SMTP objects in the dot net framework) before sending.</p>
<p>Currently all the available editors we can find have one of the following issues:</p>
<ol>
<li><p>They rely on mshtml.dll or the web browser control which as proven for us to be unreliable as the HTML code and the editor get out of sync under windows 2000 (IE6)</p></li>
<li><p>They are web-based, not a windows form control </p></li>
<li><p>They place styles in the head of the document (see note below)</p></li>
</ol>
<p>Unfortunately, as this <a href="http://www.xavierfrenette.com/articles/css-support-in-webmail/" rel="nofollow noreferrer">HTML email article</a> descries the only sure way of making HTML emails to work with styles is to use them inline which now seems to be unsupported in many editors.</p>
<p>Does anyone have any experience in this or could suggest a solution?</p>

8,612 | <p>I have a workspace for running an H.263 Video Encoder in a loop for 31 times i.e. the main is executed 31 times to generate 31 different encoded bit streams. This MS Visual Studio 2005 Workspace has all C source files. When i create a "DEBUG" configuration for the workspace and build and execute it, it runs fine, i.e. it generates all the 31 output files as expected.
But when I set the configuration of the workspace to "RELEASE" mdoe, and repeat the process, the encoder crashes at some test case run.</p>
<p>Now to debug this is verified following:</p>
<ol>
<li>Analyzed the code to see if there was any variable initialization being missed out in every run of the encoder </li>
<li>Checked the various Workspace(Solution) options in both the modes (DEBUG and RELEASE). </li>
</ol>
<p>There are some obvious differences, but i turned the optimization related options explicitly same in both modes. </p>
<p>But still could not nail the problem and find a fix for that. Any pointers?</p>
<p>-Ajit.</p>

8,625 | <p>I have a class that I want to use to store "properties" for another class. These properties simply have a name and a value. Ideally, what I would like is to be able to add <em>typed</em> properties, so that the "value" returned is always of the type that I want it to be.</p>
<p>The type should always be a primitive. This class subclasses an abstract class which basically stores the name and value as string. The idea being that this subclass will add some type-safety to the base class (as well as saving me on some conversion).</p>
<p>So, I have created a class which is (roughly) this:</p>
<pre><code>public class TypedProperty<DataType> : Property
{
public DataType TypedValue
{
get { // Having problems here! }
set { base.Value = value.ToString();}
}
}
</code></pre>
<p>So the question is:</p>
<p><strong>Is there a "generic" way to convert from string back to a primitive?</strong></p>
<p>I can't seem to find any generic interface that links the conversion across the board (something like <em>ITryParsable</em> would have been ideal!).</p>

<pre><code><%@ Import Namespace="System.Query" %>
</code></pre>
<p>However, this fails and tells me it cannot find the namespace.</p>
<blockquote>
<p>The type or namespace name 'Query' does not exist in the namespace 'System' </p>
</blockquote>
<p>I have also tried with no luck:</p>
<ul>
<li><code>System.Data.Linq</code></li>
<li><code>System.Linq</code></li>
<li><code>System.Xml.Linq</code></li>
</ul>
<p>I believe that .Net 3.5 is working because <code>var hello = "Hello World"</code> seems to work.</p>
<p>Can anyone help please?</p>
<p>PS: I just want to clarify that I don't use Visual Studio, I simply have a <a href="http://www.ultraedit.com/" rel="nofollow noreferrer">Text Editor</a> and write my code directly into .aspx files.</p>

8,676 | <p>Now that .NET v3.5 SP1 has been released (along with VS2008 SP1), we now have access to the .NET entity framework.</p>
<p>My question is this. When trying to decide between using the Entity Framework and LINQ to SQL as an ORM, what's the difference?</p>
<p>The way I understand it, the Entity Framework (when used with LINQ to Entities) is a 'big brother' to LINQ to SQL? If this is the case - what advantages does it have? What can it do that LINQ to SQL can't do on its own?</p>

8,681 | <p>If you're using Opera 9.5x you may notice that our client-side <a href="http://docs.jquery.com/Plugins/Validation" rel="noreferrer">JQuery.Validate</a> code is disabled here at Stack Overflow.</p>
<pre><code>function initValidation() {
if (navigator.userAgent.indexOf("Opera") != -1) return;
$("#post-text").rules("add", { required: true, minlength: 5 });
}
</code></pre>
<p>That's because it generates an exception in Opera! Of course it works in every other browser we've tried. I'm starting to seriously, seriously hate Opera.</p>
<p>This is kind of a bummer because without proper client-side validation some of our requests will fail. We haven't had time to put in complete server-side messaging when data is incomplete, so <strong>you may see the YSOD on Opera much more than other browsers</strong>, if you forget to fill out all the fields on the form.</p>
<p>Any Opera-ites want to uncomment those lines (they're on core Ask & Answer pages like this one -- just View Source and search for <code>"Opera"</code>) and give it a go?</p>

8,685 | <p>I'm trying to use <code>strtotime()</code> to respond to a button click to advance -1 and +1 days (two buttons) relative to the day advanced to on the previous click. </p>
<p><strong>Example:</strong> </p>
<ul>
<li>It's the 10th of the month, I click "-1 day" button, and now the date reads as the 9th. </li>
<li>I click the "-1 day" button again and now the readout states the 8th day. </li>
<li>I click the "+1 day" button and now the readout states it's the 9th. </li>
</ul>
<p>I understand the buttons and the displaying the date and using <code>$_GET</code> and PHP to pass info, but how do I get <code>strtotime()</code> to work on the relative date from the last time the time travel script was called?</p>
<p>My work so far has let me show yesterday and today relative to <em>now</em> but not relative to, for example, the <em>day before yesterday</em>, or the <em>day after tomorrow</em>. Or if I use my <strong>"last monday"</strong> button, the day before or after whatever that day is.</p>

8,691 | <p>For a C# UserControl on Windows Mobile (though please answer if you know it for full Windows...it might work) how do you change what shows up in the Designer Properties window for one of the Control's public Properties. For example:</p>
<pre><code>private Color blah = Color.Black;
public Color Blah
{
get { return this.blah; }
set { this.blah = value; }
}
</code></pre>
<p>This shows up for the control, but it's in the "Misc" category and has no description or default value. I've tried using the settings in System.ComponentModel like "DesignerCategory", such as:</p>
<pre><code>[DesignerCategory("Custom")]
</code></pre>
<p>But says this is only valid for class declarations... could've sworn it was the System.ComponentModel items I used before...</p>
<h3>Update:</h3>
<p>@John said:</p>
<blockquote>
<p>DesignerCatogy is used to say if the
class is a form, component etc.</p>
<p>Try this:</p>
<p>[Category("Custom")]</p>
</blockquote>
<p>Is there a particular namespace I need to use in order to get those?
I've tried those exactly and the compiler doesn't recognize them.</p>
<p>In .NETCF all I seem to have available from System.ComponentModel is:</p>
<pre><code>DataObject,
DataObjectMethod,
DefaultValue,
DesignerCategory,
DesignTimeVisible,
EditorBrowsable
</code></pre>
<p>The only one it doesn't scream at is EditorBrowsable</p>

8,704 | <p>I have an MFC application compiled with /clr and I'm trying to implement a final handler for otherwise un-caught managed exceptions. For native exceptions, overriding <code>CWinApp::ProcessWndProcException</code> works.</p>
<p>The two events suggested in Jeff's <a href="http://www.codeproject.com/KB/exception/ExceptionHandling.aspx" rel="nofollow noreferrer">CodeProject article</a>,<code>Application.ThreadException</code> and <code>AppDomain.CurrentDomain.UnhandledException</code>, are not raised.</p>
<p>Can anyone suggest a way to provide a final managed exception handler for a mixed executable?</p>
<hr>
<p>Update:</p>
<p>It appears that these exception handlers are only triggered downstream of <code>Application.Run</code> or similar (there's a worker thread flavor, can't remember the name.) If you want to truly globally catch a managed exception you do need to install an SEH filter. You're not going to get a <code>System.Exception</code> and if you want a callstack you're going to have to roll your own walker.</p>
<p>In an MSDN forum question on this topic it was suggested to override a sufficiently low-level point of the main MFC thread in a <code>try ... catch (Exception^)</code>. For instance, <code>CWinApp::Run</code>. This may be a good solution but I haven't looked at any perf or stability implications. You'll get a chance to log with a call stack before you bail and you can avoid the default windows unahndled exception behavior.</p>

8,715 | <p>Jeff mentioned in one of the podcasts that one of the things he always does is put in instrumentation for database calls, so that he can tell what queries are causing slowness etc. This is something I've measured in the past using SQL Profiler, but I'm interested in what strategies other people have used to include this as part of the application.</p>
<p>Is it simply a case of including a timer across each database call and logging the result, or is there a 'neater' way of doing it? Maybe there's a framework that does this for you already, or is there a flag I could enable in e.g. Linq-to-SQL that would provide similar functionality.</p>
<p>I mainly use c# but would also be interested in seeing methods from different languages, and I'd be more interested in a 'code' way of doing this over a db platform method like SQL Profiler.</p>

8,726 | <p>I have a script that checks responses from HTTP servers using the PEAR HTTP classes. However, I've recently found that the script fails on FTP servers (and probably anything that's not HTTP or HTTPS). I tried Google, but didn't see any scripts or code that returned the server status code from servers other than HTTP servers.</p>
<p>How can I find out the status of a newsgroup or FTP server using PHP?</p>
<p>EDIT: I should clarify that I am interested only in the ability to read from an FTP server and the directory that I specify. I need to know if the server is dead/gone, I'm not authorized to read, etc.</p>
<p>Please note that, although most of the time I'm language agnostic, the entire website is PHP-driven, so a PHP solution would be the best for easy of maintainability and extensibility in the future.</p>

8,742 | <p>I'm trying to rebuild an old metronome application that was originally written using MFC in C++ to be written in .NET using C#. One of the issues I'm running into is getting the timer to "tick" accurately enough.</p>
<p>For example, assuming an easy BPM (beats per minute) of 120, the timer should tick every .5 seconds (or 500 milliseconds). Using this as the basis for the ticks, however, isn't entirely accurate as .NET only guarantees that your timer will not tick before the elapsed time has passed.</p>
<p>Currently, to get around this for the same 120 BPM example used above, I am setting the ticks to something like 100 milliseconds and only playing the click sound on every 5th timer tick. This does improve the accuracy quite a bit, but if feels like a bit of a hack.</p>
<p>So, what is the best way to get accurate ticks? I know there are more timers available than the windows forms timer that is readily available in Visual Studio, but I'm not really familiar with them.</p>

8,756 | <p>Does anyone have any good starting points for me when looking at making web pages/sites/applications specifically for viewing on the iPhone?</p>
<p>I've looked at templates like the one <a href="http://blog.wired.com/monkeybites/2007/07/meet-joe-hewitt.html" rel="noreferrer">Joe Hewitt</a> has made, and also seen some templates I can purchase, which I haven't done yet.</p>
<p>I figured someone else had already started on this track and decided that I could probably leech on their newfound knowledge :)</p>
<p>So, does anyone have any pointers? I'm well aware of the problem that the more such a template/framework makes a web app look like a native iPhone app, the more likely I'm going to get into trouble because it just isn't, but for now I want a framework I can start building on, and then in the process figure out how to make it distinctive enough to be perceived as a web app as well as looking like a native iPhone application.</p>
<p>Specifically I'm looking for features like:</p>
<ul>
<li>stylesheets set up, or pointers to how to do them for iPhone</li>
<li>page flipping animation, ie. pick an item in a list, list scrolls out of view to the left and information for item scrolls in from the right</li>
<li>the animation part would have to work with dynamic pages, ie. not just one big page that has divs set up for each sub-item, which at least one such framework had as a sort of quick fix, I would need to have list item picking load the <em>page</em> for that item, and then when loaded, scroll to it</li>
</ul>
<hr>
<p><strong>Edit</strong>: To avoid people reading only the question and answering, before reading my other reply, I'll add my clarification for GPL licensing and similar issues here.</p>
<p>The framework I need to use can not be distributed under a license which would require me to license my own project out under a similar license. The GPL family of licenses allows for exceptions regarding library usage, but this won't apply to this since by necessity, the kind of framework I would need to use would be all source code.</p>
<p>The project can easily accomodate commercial libraries.</p>
<p>Also, I don't need a <em>library</em> or a <em>framework</em> as such, example files that look good and aren't overly obfuscated would be welcome as well.</p>

8,761 | <p>I'm updating some of our legacy C++ code to use the "MFC feature pack" that Microsoft released for Visual Studio 2008. We've used the new classes to derive our application from CFrameWndEx, and are applying the Office 2007 styles to give our application a more modern appearance. This gives us gradient filled window titles, status bars etc, and the use of the ribbon toolbars.</p>
<p>However, our application contains some owner drawn controls, and I'd like to update these to match the color scheme used by the feature pack. Ideally I'd like to know the light and shaded toolbar colors that are currently in use.</p>
<p>I've had a hunt around the documentation and web and have not yet found anything. Does anyone know how to find this information out?</p>
<p>[Edit]</p>
<p>In particular we need to find out which colors are being used at runtime. You can change the appearance of your application at runtime using the new static function CMFCVisualManager::SetDefaultManager.</p>
<p>The following msdn page shows you what kind of styles are available, in particular the Office2007 look:

8,763 | <p>I'm trying to rebuild an old metronome application that was originally written using <code>MFC</code> in C++ to be written in <code>.NET</code> using <code>C#</code>. One of the issues I'm running into is playing the midi files that are used to represent the metronome "clicks".</p>
<p>I've found a few articles online about playing <code>MIDI</code> in .NET, but most of them seem to rely on custom libraries that someone has cobbled together and made available. I'm not averse to using these, but I'd rather understand for myself how this is being done, since it seems like it <em>should</em> be a mostly trivial exercise.</p>
<p>So, am I missing something? Or is it just difficult to use MIDI inside of a .NET application?</p>

8,790 | <p>I have a build script and as part of that script it copies a jar file to a directory, for ease lets call it the utils jar. the utils jar is built by another build script sitting in another directory. What im trying to do have my build script run the utils build script so that I can ensure the utils jar is up to date.</p>
<p>So I know I need to import the utils build file.</p>
<pre><code><import file="../utils/build/build.xml" />
</code></pre>
<p>Which doesn't work because the import task, unlike almost every other ant taks, doesn't run from basedir, it runs from the pwd. So to get around that I have this little ditty, which does successfully import the build file</p>
<pre><code> <property name="baseDirUpOne" location=".." />
<import file="${baseDirUpOne}/utils/build/build.xml" />
</code></pre>
<p>So now that ive solved my import problem I need to call the task, well that should be easy right:</p>
<pre><code><antcall target="utils.package" />
</code></pre>
<p><em>note that in the above, utils is the project name of ../utils/build/build.xml</em></p>
<p>the problem I'm now running into is that ant call doesn't execute in ../utils/build so what I need, and cant find, is a runat property or something similar, essentially:</p>
<pre><code><antcall target="utils.package" runat="../utils/build" />
</code></pre>
<p>The reason I need this is that in my utils build file the step to select which code to copy to the jar is based on relative paths so as to avoid hardcoding paths in my ant file. Any ideas? </p>

8,795 | <p>I would like to create a stored procedure in MySQL that took a list as argument. For example, say that I would like to be able to set multiple tags for an item in one call, then what I want to do is to define a procedure that takes the ID of the item and a list of tags to set. However, I can't seem to find any way to do this, there is no list datatype, as far as I'm aware, but can it be emulated somehow? Could the list of tags be a comma-separated string, which can somehow be split and looped over?</p>
<p>How do you usually work with lists in MySQL stored procedures?</p>

8,800 | <p>So I've been poking around with C# a bit lately, and all the Generic Collections have me a little confused. Say I wanted to represent a data structure where the head of a tree was a key value pair, and then there is one optional list of key value pairs below that (but no more levels than these). Would this be suitable?</p>
<pre><code>public class TokenTree
{
public TokenTree()
{
/* I must admit to not fully understanding this,
* I got it from msdn. As far as I can tell, IDictionary is an
* interface, and Dictionary is the default implementation of
* that interface, right?
*/
SubPairs = new Dictionary<string, string>();
}
public string Key;
public string Value;
public IDictionary<string, string> SubPairs;
}
</code></pre>
<p>It's only really a simple shunt for passing around data.</p>

8,832 | <p>I hope I can explain this clearly enough, but if not let me know and I'll try to clarify.</p>
<p>I'm currently developing a site using ColdFusion and have a mod_rewrite rule in place to make it look like the site is using PHP. Any requests for index.php get processed by index.cfm (the rule maps *.php to *.cfm).</p>
<p>This works great - so far, so good. The problem is that I want to return a 404 status code if index.cfm (or any ColdFusion page) is requested directly.</p>
<p>If I try to block access to *.cfm files using mod_rewrite it also returns a 404 for requests to *.php.</p>
<p>I figure I might have to change my Apache config rather than use .htaccess</p>

8,896 | <p>Does anyone know <strong>IF</strong>, <strong>WHEN</strong> or <strong>HOW</strong> I can get <a href="https://memcached.org/" rel="noreferrer">Memcached</a> running on a Windows 64bit environment? </p>
<p>I'm setting up a new hosting solution and would much prefer to run a 64bit OS, and since it's an ASP.Net MVC solution with SQL Server DB, the OS is either going to be Windows Server 2003 or (hopefully!) 2008.</p>
<p>I know that this could spill over into a debate regarding 32bit vs 64bit on servers, but let's just say that my preference is 64bit and that I have some <a href="https://blogs.technet.microsoft.com/mscom/2005/09/26/running-microsoft-com-on-64-bitthe-dependencies-the-goodness-the-gotchas/" rel="noreferrer">very</a> <a href="https://blog.codinghorror.com/64-bit-desktop-vs-64-bit-server/" rel="noreferrer">good</a> reasons.</p>
<p>So far, I've tried a number of options and found a <a href="http://blog.rakeshxp.com/2007/09/running-memcached-on-windows.html" rel="noreferrer">bit</a> of <a href="http://www.splinedancer.com/memcached-win32/" rel="noreferrer">help</a> related to getting this up on a 32bit machine (and succeeded I might add), but since the original <a href="http://jehiah.cz/projects/memcached-win32/" rel="noreferrer">Windows port</a> is Win32 specific, this is hardly going to help when installing as a service on x64. It also has a dependency on the <a href="https://libevent.org/" rel="noreferrer">libevent</a> for which I can only get a Win32 compiled version.</p>
<p>I suspect that simply loading all this up in C++ and hitting "compile" (for 64bit) wouldn't work, not least because of the intricate differences in 32 and 64bit architectures, but I'm wondering if anyone is working on getting this off the ground? Unfortunately, my expertise lie in managed code (C#) only, otherwise I would try and take this on myself, but I can't believe I'm the only guy out there trying to get <a href="https://memcached.org/" rel="noreferrer">memcached</a> running on a 64 bit Windows server....am I?</p>
<hr>
<p>Update</p>
<p><strong>Yes I'm afraid I'm still looking for an answer to this - all my efforts (with my pathetic C++ skills) to make a stable build have failed - I've trashed one server and 3 VM's just trying it out so now I turn to the real experts.
Is anyone planning on porting this to 64bit? Or are you really suggesting that I use MS Velocity instead? I shudder at the thought.</strong></p>
<hr>
<p>Update:
@Lars - I do use Enyim actually - it's very good, but what you're referring to is a client, rather than the server part.</p>
<p>@DannySmurf - I've only been able to install it as a service on a 32 bit OS. 64 bit OS rejects the installation of this Win32 service. Of course yes, lots of Win32 code works seamlessly on x64 architecture, hence you can run 32bit apps (like Office for instance) or games on Vista/XP 64 etc, but this doesn't translate directly when it comes to services. I'm no expert, I suspect that it has to do with the syncs or eventing that services need to subscribe to, and I suspect that 64 and 32 don't play nicely. I'm happy to be corrected on any of this, but to answer your question - yes I have tried.</p>
<p>@OJ - thanks very much for the straight-forward response. I thought as much, but wasn't sure if anyone else had suggestions or had already gone down this route. Maybe when StackOverflow is LIVE, then more people will respond and let me know if this is something being looked into, and although I can try and compile it myself - I simply can't "trust" (with my C++ experience level) that it would provide "Enterprise Level" reliability in such a crucial component of large scalable solutions. I think it would need educated intervention rather than my unsanitised experimental approach before I could be confident. One little oversight on my part, could bring the site down. Oh well... till next time.</p>

8,941 | <p><strong>Is there a way to enforce/limit the types that are passed to primitives?</strong> <em>(bool, int, string, etc.)</em></p>
<p>Now, I know you can limit the generic type parameter to a type or interface implementation via the <em>where</em> clause. However, this doesn't fit the bill for primitives (AFAIK) because they do not all have a common ground (apart from <em>object</em> before someone says! :P).</p>
<p>So, my current thoughts are to just grit my teeth and do a big <em>switch</em> statement and throw an <em>ArgumentException</em> on failure.</p>
<hr />
<p><strong>EDIT 1:</strong></p>
<p>Just to clarify:</p>
<p>The code definition should be like this:</p>
<pre><code>public class MyClass<GenericType> ....
</code></pre>
<p>And instantiation:</p>
<pre><code>MyClass<bool> = new MyClass<bool>(); // Legal
MyClass<string> = new MyClass<string>(); // Legal
MyClass<DataSet> = new MyClass<DataSet>(); // Illegal
MyClass<RobsFunkyHat> = new MyClass<RobsFunkyHat>(); // Illegal (but looks awesome!)
</code></pre>
<hr />
<p><strong>EDIT 2</strong></p>
<p>@Jon Limjap - Good point, and something I was already considering. I'm sure there is a generic method that can be used to determine if the type is of a value or reference type.</p>
<p>This could be useful in instantly removing a lot of the objects I don't want to deal with (but then you need to worry about the structs that are used such as <em>Size</em> ). Interesting problem no? :)</p>
<p>Here it is:</p>
<pre><code>where T: struct
</code></pre>
<p>Taken from <a href="http://msdn.microsoft.com/en-us/library/d5x73970.aspx" rel="nofollow noreferrer">MSDN</a>.</p>
<hr />
<p>I'm curious. Could this be done in .NET 3.x using extension methods? Create an interface, and implement the interface in the extension methods (which would probably be cleaner than a bit fat switch). Plus if you then need to later extend to any lightweight custom types, they can also implement the same interface, with no changes required to the base code.</p>
<p>What do you guys think?</p>
<p>The sad news is I am working in Framework 2!! :D</p>
<hr />
<p><strong>EDIT 3</strong></p>
<p>This was so simple following on from <a href="https://stackoverflow.com/questions/8941/generic-type-checking#8956">Jon Limjaps Pointer</a>.. So simple I almost want to cry, but it's great because the code works like a charm!</p>
<p>So here is what I did (you'll laugh!):</p>
<h2>Code added to the generic class</h2>
<pre><code>bool TypeValid()
{
// Get the TypeCode from the Primitive Type
TypeCode code = Type.GetTypeCode(typeof(PrimitiveDataType));
// All of the TypeCode Enumeration refer Primitive Types
// with the exception of Object and Empty (Null).
// Since I am willing to allow Null Types (at this time)
// all we need to check for is Object!
switch (code)
{
case TypeCode.Object:
return false;
default:
return true;
}
}
</code></pre>
<p>Then a little utility method to check the type and throw an exception,</p>
<pre><code>private void EnforcePrimitiveType()
{
if (!TypeValid())
throw new InvalidOperationException(
"Unable to Instantiate SimpleMetadata based on the Generic Type of '" + typeof(PrimitiveDataType).Name +
"' - this Class is Designed to Work with Primitive Data Types Only.");
}
</code></pre>
<p>All that then needs to be done is to call <em>EnforcePrimitiveType()</em> in the classes constructors. Job done! :-)</p>
<p>The only downside, it only throws an exception at runtime (obviously) rather than design time. But that's no big deal and could be picked up with utilities like <a href="http://en.wikipedia.org/wiki/FxCop" rel="nofollow noreferrer">FxCop</a> (which we don't use at work).</p>
<p>Special thanks to Jon Limjap on this one!</p>

8,966 | <p>I want to implement a paperless filing system and was looking to use WIA with C# for the image acquisition. There are quite a few sample projects on CodeProject, etc. However, after downloading every one of them that I can find, I have run into a problem.</p>
<p>In each and every one of them, the reference to WIALib is broken. When I go to add "Microsoft Windows Image Acquisition" as a reference, the only version available on my development workstation (also the machine that will run this) is 2.0.</p>
<p>Unfortunately, every one of these sample projects appear to have been coded against 1.x. The reference goes in as "WIA" instead of "WIALib". I took a shot, just changing the namespace import, but clearly the API is drastically different.</p>
<p>Is there any information on either implementing v2.0 or on upgrading one of these existing sample projects out there?</p>

9,002 | <p>When I use the sp_send_dbmail stored procedure, I get a message saying that my mail was queued. However, it never seems to get delivered. I can see them in the queue if I run this SQL:</p>
<pre><code>SELECT * FROM msdb..sysmail_allitems WHERE sent_status = 'unsent'
</code></pre>
<p>This SQL returns a 1:</p>
<pre><code>SELECT is_broker_enabled FROM sys.databases WHERE name = 'msdb'
</code></pre>
<p>This stored procedure returns STARTED:</p>
<pre><code>msdb.dbo.sysmail_help_status_sp
</code></pre>
<p>The appropriate accounts and profiles have been set up and the mail was functioning at one point. There are no errors in msdb.dbo.sysmail_event_log. </p>

9,018 | <p>I am working at a client site where there is a proxy server (<code>HTTP</code>) in place. If I do a hard reset of the emulator it forgets network connection settings for the emulator and settings in the hosted Windows Mobile OS. If I 'save state and exit' it will lose all of these settings. I need to do hard resets regularly which means that I lose this information and spend a lot of time setting:</p>
<ul>
<li>The emulators associated network card</li>
<li>DNS servers for network card in the WM OS.</li>
<li>Proxy servers in connection settings of WM OS.</li>
</ul>
<p>How can I make my life easier? Can I save this as defaults in the emulator, or create an installer easily?</p>

9,019 | <p>I have a stored procedure which takes as its parameter a <em>varchar</em> which needs to be cast as a <em>datetime</em> for later use:</p>
<pre><code>SET @the_date = CAST(@date_string AS DATETIME)
</code></pre>
<p>I'm expecting the date string to be supplied in the format "DD-MON-YYYY", but in an effort to code defensively, if for some reason it can't be cast successfully, I want to default to the system date and continue. In PL/SQL I could use exception handling to achieve this and I could do this fairly easily with regular expressions too, but the limited pattern matching supported out of the box by Sybase doesn't let me do this and I can't rely on third party libraries or extensions. Is there a simple way of doing this in T-SQL?</p>
<p><em>NB: using Sybase ASE 12.5.3, there is no ISDATE function</em></p>

9,022 | <p>Inside an asp.net page, should I use</p>
<pre><code><html><title>My page's title from México</title></html>
</code></pre>
<p>Or </p>
<pre><code><html><title>My page&rsquo;s title from M&eacute;xico</title></html>
</code></pre>
<p>Both examples have the same output. Since asp.net encodes all my pages to utf-8, there is no need to use html entities, is that right?</p>

9,044 | <p>I have a base class that represents a database test in TestNG, and I want to specify that all classes extending from this class are of a group "db-test", however I have found that this doesn't seem possible. I have tried the @Test annotation:</p>
<pre><code>@Test(groups = { "db-test" })
public class DBTestBase {
}
</code></pre>
<p>However, this doesn't work because the @Test annotation will try to make a bunch of methods into tests, and warnings/errors pop up in eclipse when the tests are run.</p>
<p>So I tried disabling the test, so at least the groups are assigned:</p>
<pre><code>@Test(enabled = false, groups = { "db-test" })
public class DBTestBase {
}
</code></pre>
<p>but then any @BeforeTest (and other similar annotations) ALSO get disabled... which is of course not what I want.</p>
<p>I would like some way to annotate a class as being of a particular type of group, but it doesn't quite seem possible in TestNG. Does anyone have any other ideas?</p>

strUser = ActiveDirectory.User()
MsgBox "Welcome back, " & strUser

9,104 | <p>I'm thinking that the reason I can't do this is because it might be a huge security hole, but here goes...</p>
<p>I want to have a bookmark on my browser (FF3, preferably) that is only a snippet of javascript code. It would merely construct a URL based on the current date and then do a window.location = on that URL.</p>
<p>I know that I could make a page and keep it on my local machine and just refer to it that way, but I was just wondering if you could bypass that step and actually have the "location" of the bookmark really just be javascript. I could have sworn that this was possible years ago, but I can't find anything that tells me either way now.</p>

9,173 | <p>My C# project - we'll call it the SuperUI - used to make use of a class from an external assembly. Now it doesn't, but the compiler won't let me build the project without the assembly reference in place. Let me elaborate.</p>
<p>This project used to throw and catch a custom exception class - the <code>SuperException</code> - which was derived from the standard System.Exception and lived in a separate, precompiled assembly, <code>SuperAssembly.DLL</code>, which I referenced.</p>
<p>Eventually, I decided this was a pointless exercise and replaced all <code>SuperExceptions</code> with a System.SuitableStandardException in each case. I removed the reference to <code>SuperException.DLL</code>, but am now met with the following on trying to compile the project:</p>
<blockquote>
<p>The type 'SuperException' is defined in an assembly that is not referenced. You must add a reference to assembly 'SuperException, Version=1.1.0.0 (...)'</p>
</blockquote>
<p>The source file referenced by the error doesn't seem relevant; it's the project namespace that gets highlighted in the IDE.</p>
<p>Now, here's the thing:</p>
<ol>
<li>All uses of <code>SuperException</code> have been eliminated from the project's code.</li>
<li>Compared to another project that compiles fine without a reference to <code>SuperException.DLL</code>, I only reference one more assembly - and <code>that</code> references nothing that my project doesn't reference itself. While it's possible that any of these dependencies could throw <code>SuperExceptions</code>, I'm only catching the base Exception class and in any case... the other project builds fine!</li>
<li>I've done Visual Studio's "Clean Solution" and cleared everything out by hand, many times.</li>
</ol>
<p>It's not the end of the world to include this reference, I just don't see why it's necessary any more. Nrrrgg. Any pointers welcome!</p>

9,191 | <p>I'd like to ask a question then follow it up with my own answer, but also see what answers other people have.</p>
<p>We have two large files which we'd like to read from two separate threads concurrently. One thread will sequentially read fileA while the other thread will sequentially read fileB. There is no locking or communication between the threads, both are sequentially reading as fast as they can, and both are immediately discarding the data they read.</p>
<p>Our experience with this setup on Windows is very poor. The combined throughput of the two threads is in the order of 2-3 MiB/sec. The drive seems to be spending most of its time seeking backwards and forwards between the two files, presumably reading very little after each seek.</p>
<p>If we disable one of the threads and temporarily look at the performance of a single thread then we get much better bandwidth (~45 MiB/sec for this machine). So clearly the bad two-thread performance is an artefact of the OS disk scheduler.</p>
<p><strong>Is there anything we can do to improve the concurrent thread read performance?</strong> Perhaps by using different APIs or by tweaking the OS disk scheduler parameters in some way.</p>
<p>Some details:</p>
<p>The files are in the order of 2 GiB each on a machine with 2GiB of RAM. For the purpose of this question we consider them not to be cached and perfectly defragmented. We have used defrag tools and rebooted to ensure this is the case.</p>
<p>We are using no special APIs to read these files. The behaviour is repeatable across various bog-standard APIs such as Win32's CreateFile, C's fopen, C++'s std::ifstream, Java's FileInputStream, etc.</p>
<p>Each thread spins in a loop making calls to the read function. We have varied the number of bytes requested from the API each iteration from values between 1KiB up to 128MiB. Varying this has had no effect, so clearly the amount the OS is physically reading after each disk seek is not dictated by this number. This is exactly what should be expected.</p>
<p>The dramatic difference between one-thread and two-thread performance is repeatable across Windows 2000, Windows XP (32-bit and 64-bit), Windows Server 2003, and also with and without hardware RAID5.</p>

9,204 | <p>Is there any IL level debugger in form of a VS plugin or standalone application?</p>
<p>Visual studio’s debugger is great, but it allows you to debug on either HLL code level or assembly language, you can’t debug IL.
It seems that in some situations it would be useful to have an opportunity to debug at IL level. </p>
<p>In particular it might be helpful when debugging a problem in the code that you don't have the source of.</p>
<p>It is arguable if it is actually useful to debug IL when you don't have the source, but anyway.</p>

9,240 | <p>Say you have an application divided into 3-tiers: GUI, business logic, and data access. In your business logic layer you have described your business objects: getters, setters, accessors, and so on... you get the idea. The interface to the business logic layer guarantees safe usage of the business logic, so all the methods and accessors you call will validate input. </p>
<p>This great when you first write the UI code, because you have a neatly defined interface that you can trust.</p>
<p>But here comes the tricky part, when you start writing the data access layer, the interface to the business logic does not accommodate your needs. You need to have more accessors and getters to set fields which are/used to be hidden. Now you are forced to erode the interface of your business logic; now it is possible set fields from the UI layer, which the UI layer has no business setting. </p>
<p>Because of the changes needed for the data access layer, the interface to the business logic has eroded to the point where it is possible to even set the business logic with invalid data. Thus, the interface does not guarantee safe usage anymore.</p>
<p>I hope I explained the problem clearly enough. How do you prevent interface eroding, maintain information hiding and encapsulation, and yet still accommodate different interface needs among different layers? </p>
