<p>When I enable common control visual style support (InitCommonControls()) and I am using any theme other then Windows Classic Theme, buttons inside a group box appear with a black border with square corners. </p>
<p>Windows Classic Theme appears normal, as well as when I turn off visual styling.</p>
<p>I am using t... | <p>The problem is having the groupbox as the controls' parent. Groupboxes are not supposed to have any children and using them as parents will cause all kinds of errors (including painting, keyboard navigation and message propagation).

Although I'm not sure if this will work for VC++ 2008, but back-in-the-day the solution for VB6 themed apps was to put the radio controls on a PictureBox (a generic container really) first and then add that to the group box.</p>

<p>I am getting a DC for a window handle of an object in another program using win32gui.GetDC which returns an int/long. I need to blit this DC into a memory DC in python. The only thing I can't figure out how to do is get a wxDC derived object from the int/long that win32gui returns. None of the wxDC objects allow ... | <p>I downloaded the wxWidgets source and dug around, and I think this will work.</p>
<p>You need the handle (HWND) for the external window, not the DC.</p>
<pre><code>window = wx.Frame(None, -1, '')
window.AssociateHandle(hwnd)
dc = wx.WindowDC(window)
</code></pre>
| <p>From what I can tell, DCs in python are abstracted due to platform variation. So a device context in python doesn't directly map to a device context in Windows even though many of the methods are direct Windows method calls. To make this happen it appears you would need to make your own DelegateDC class or somethi... | 30,297 |
<p>I'm working my way into MVC at the moment, but on my "To learn at some point" list, I also have WCF.</p>
<p>I just wonder if WCF is something that should/could be used in an MVC Application or not? The Background is that I want a Desktop Application (.NET 3.5, WPF) interact with my MVC Web Site, and I wonder what t... | <p>WCF services might make sense in this situation, but don't create services that align with your UI, create services that align with the business processes. ie. you won't have a service that returns the view data for each page, you will have a service that exposes logical operations.

<p>I'm having some minor problems with some animations I'm trying to set up. I have a couple divs stacked on top of each other kind of like this.</p>

Stuff...
</div>
<div id="div2">
More Stuff...

<p>Each of these divs has a drop shadow app... | <p>I would suggest using <strong>CSS</strong> for your drop shadows, and <strong>not JS</strong>.</p>
<p>I have dealt with this exact problem in the past and I have completely stopped using JS for drop shadows. I have never seen animations with JS shadows look as smooth as pure CSS. Also, using too much JS to alter ... | <p>Ok, I still don't know how you animate, but I give you another example:</p>
<pre><code>$('#foo').slideToggle().ready(function(){
$('#foo').dropShadow(options);
});
</code></pre>
<p>So, instead of <code>slideToggle</code>, just use whatever animation <em>thingy</em> you got.</p>
<p>Hope that helps.</p>
