<p>I need to create a ListBox with the WrapPanel ItemsTemplate. </p>
<p>My item is displayed as a card with small top "toolbar" that is displaying dynamically on mouse over.</p>
<p>[ dyn. toolbar ]
[ card ]</p>
<p>Everything is running well except the first line. </p>
<p>I need to have cards very close ea... | <p>I'm not sure I fully understand your question, but if you're displaying the toolbar above the card using a negative top margin, couldn't you compensate for this by dynamically setting a positive margin on the card whenever the toolbar is shown?</p>
| <p>Xaml would be helpful. One rule of thumb I've found is to never set the actual height or width properties of a control. Try taking out the height property and that should get rid of the clipping. You should be able to get any spacing you need figured out with Margin, Padding, or MinHeight.</p>

<p>I have to POST some parameters to a URL outside my network, and the developers on the other side asked me to not use HTTP Parameters: instead I have to post my key-values in <strong>HTTP Headers</strong>.</p>
<p>The fact is that I don't really understand what they mean: I tried to use a ajax-like post, with XmlHttp... | <p>Like @lassevk said, a redirect won't work.</p>
<p>You should use the WebRequest class to do an HTTP POST from your page or application. There's an example <a href="http://msdn.microsoft.com/en-us/library/debx8sh9.aspx" rel="nofollow noreferrer">here</a>.</p>
| <p>You should post more information.</p>
<p>For instance, is this C#? It looks like it, but I might be wrong.</p>
<p>Also, you say you get an exception, what is the exception type and message?</p>
<p>In any case, you can't redirect to a page for POST, you need to submit it from the browser, not from the server redir... | 6,167 |
<p>I'm looking for a good audio compression library for .NET. Anything using MP3 is out (because of the licensing issue). Basically I just need to be able to compress regular WAV audio data into some format, and decompress back to WAV. Preferably the code would be all .NET (C# or VB.NET), but I don't think this is l... | <p>Have you thought about using WMA? If you use managed C++ or C++/CLI it's very easy to write a managed wrapper around the Windows Media Format SDK. This assembly can then be easily used by a higher level VB.Net or C# assembly. As long as you have WMP installed it even has the advantage of not requiring any additional... | <p>You might look into OGG codecs. I'm not sure if there are any written in .NET, but it's open source, so if this is important to you, you should be able to to port one easily enough.</p>
