PRB: Most Common Cause of SetPixelFormat() Failure

RESOLUTION

Include WS_CLIPCHILDREN and WS_CLIPSIBLINGS window styles when in a Win32- based application, you use Microsoft's implementation of OpenGL to render onto a window.

Additionally, the window class attribute should not include the CS_PARENTDC style. The two window styles can be added to the dwStyles parameter of CreateWindow() or CreateWindowEX() call. If MFC is used, override PreCreateWindow() to add the flags. For example:

   BOOL CMyView::PreCreateWindow(CREATESTRUCT& cs)
   {
       cs.style |= (WS_CLIPCHILDREN | WS_CLIPSIBLINGS);

       return CView::PreCreateWindow(cs);
   }
