about surface

I don''t really know that much, but have you tried using FlipToGDISruface? That would be the only thing that I could think of. Hope this helps!

Hello...
I am a programmer from Taiwan..
I get into a big trouble..I create the primary
surface under the CMainFram class window
creating by VC++6.0. I use DDShow to play
the AVI file. The last frame always remain on
the screen. then I use Create() to create a button
, but the button is always invisible. If I teminate the
program, the button will show once. I am wondering
if the primary surface can not co-exist with the CWnd
window class creating by MFC ? It seems that the button
is behide the primary surface. Does any method resolve
this problem..?..I have tried for many days..I almost go
crazy,,,,Longing for your kindly help....Thank you....

I also have been struggling since the release of DirectX 8.0 to try to get an avi file to play on a directdraw surface. I am not very expert, but will offer what I think I have learned. Apparently, if you set the cooperative level to EXCLUSIVE in creating a DirectDraw Surface originally then you MUST go through the Overlay Mixer to stream video. Check out the DirectDraw Exclusive Demo (ddrawxcl) in the samples directory of DDSHow for an exapmle of a Class based approach to implenting the overlay mixer and displaying an avi file. I haven''t yet had a chance to try to integrate this code into my current directdraw project, but maybe it will give you some ideas. I would be interested in the code you have created because i want the last frame of an avi to remain on the screen until the user clicks the mouse for the next scene. Can you post the code?
