How do you inintialize the pixel format for a MDI window? Is that you forgot to specify PFD_DOUBLEBUFFER for its pixel format?

This is my function to set pixel format…

BOOL CCADCorTexView::SetWindowPixelFormat(HDC hDC)
{
PIXELFORMATDESCRIPTOR pixelDesc;
pixelDesc.nSize = sizeof(PIXELFORMATDESCRIPTOR);
pixelDesc.nVersion = 1;
pixelDesc.dwFlags = PFD_DRAW_TO_WINDOW |
PFD_DRAW_TO_BITMAP |
PFD_SUPPORT_OPENGL |
PFD_SUPPORT_GDI |
PFD_DOUBLEBUFFER | …

PFD_DOUBLEBUFFER

look what MSDN says:

“PFD_SUPPORT_GDI: The buffer supports GDI drawing. This flag and PFD_DOUBLEBUFFER are mutually exclusive in the current generic implementation.”

and vice versa.

Thanks!! I got it running smooth now!

i am glad for ya!
