<p>What kinds of hook scripts are people using for Subversion? Just general ideas but code would be great too!</p>
| <p>I am using the <code>pre-revprop-change</code> hook that allows me to actually go back and edit comments and such information after the commit has been performed. This is very useful if there is missing/erroneous information in the commit comments.</p>
<p>Here I post a <code>pre-revprop-change.bat</code> batch file... | <p>The most common one I think is to allow people to change revision comments after comitting. </p>
<p>You need to enable the 'pre-revprop-change' hook script to allow that. The example provided, if enabled allows editing only the comment property and only be the original comitter. Great for correcting typos.</p>

<p>How can I bring my WPF application to the front of the desktop? So far I've tried:</p>
<pre><code>SwitchToThisWindow(new WindowInteropHelper(Application.Current.MainWindow).Handle, true);
SetWindowPos(new WindowInteropHelper(Application.Current.MainWindow).Handle, IntPtr.Zero, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);... | <pre><code>myWindow.Activate();

<p><em>Attempts to bring the window to the foreground and activates it.</em></p>

<p>Instead of writing my ASP.NET C# applications in Visual Studio, I used my favorite text editor UltraEdit32.</p>
<p>Is there any way I can implement MVC without the use of VS?</p>
| <p>There is nothing VS specific with the MVC framework - it is just a bunch of DLLs that you can use. The wizards in VS just build you a quick-start framework.</p>
<p>ASP.NET MVC is "bin-deployable" - there is nothing too clever to set up on the server either - just point the wildcard ISAPI filter to ASP.NET</p>
| <p>For small to mid size mvc project <a href="http://www.microsoft.com/web/webmatrix/" rel="nofollow">WebMatrix</a> is not bad at all. Also for simple changes to the projects I often use SublimeText.</p>
