• Visual Studio 2008 (Pre-release) BitmapEffect and MediaElement

  It seems applying any BitmapEffect to a MediaElement will cause it to render only a black box (audio still plays). Is this expected behavior Must I do something with BitmapEffectInput Unfortunately applying a BitmapEffect to a MediaElement is unsupported in current builds of WinFx. We’re investigating a fix for this, but make no guarantees that it will be fixed for the final bits. If you’d like to get it to work, there is a simple (but kind of expensive) work around. With the BitmapEffect applied to the MediaElement, try animating the width of the MediaElement very slightly. This will force an update and h ...Show All

• Visual Studio Team System How to hide code coverage coloring?

  OK, coloring the code after code coverage is great.  Now how do I turn it off I'm not talking about no longer doing code coverage - I just want all the coloring to go away so I can work on the code without all that visual noise. Yes, I was referring to the context menu in the text editor, but  I don't see a compelling need to have the control on a file by file basis - it's just one of the places I'd looked for it.  I agree that the View menu is the most sensible place - analogous to Tab Order when the forms designer is open. ...Show All

• Visual C++ Tracking Reference (%), value, ref??

  For a while now I have been reading the documentation, for Visual C++ 2005, in an attempt to migrate from native code to managed. I find it hard to understand how to use the different types, and what the equvivalent in native code is. Look at this code: ref class rc{}; value class vc{}; f1(rc^ c1){} f2(rc^% c1){} is rc^ myrc = gcnew rc; equvivalent to rc * myrcN = new rc; in native code And is " Handle to Object on Managed Heap " the same as " Pointer to Object " What is the difference of ref and value If i want a object on managed heap do I use the "ref" keyword, and value keyword if I want it on ...Show All

• Windows Forms Copying 1 APP to Another
