How can I backbuffer in GDI? I tried this but it wont draw anything: RECT Rect; GetClientRect(GetMainWindow(),&Rect); HDC hDC = GetDC(GetMainWindow()); HDC BackBuffer = CreateCompatibleDC(hDC); FillRect(BackBuffer,&Rect,(HBRUSH)GetStockObject(BLACK_BRUSH)); BitBlt(hDC,0,0,800,600,BackBuffer,0,0,SRCCOPY);

You need to use a memory device context
The article is for MFC but I think it shouldn't be a big deal to convert it to GDI/Win32.
Hope this helps,
Cheers.

Here's sample code in C for a dinky little Win 32 GDI particle spewing toy. YMMV.
