I am having a hard time with this stuff. What I am trying to do is gett a pointer to a back buffer attatched to a direct draw 7 primary surface. Here is my code: DDSURFACEDESC2 ddsd_primary; DDSCAPS2 ddscaps; ZeroMemory(&ddsd_primary, sizeof(ddsd_primary)); ddsd_primary.dwSize = sizeof(DDSURFACEDESC2); ddsd_primary.dwFlags = DDSD_CAPS | DDSD_BACKBUFFERCOUNT; ddsd_primary.ddsCaps.dwCaps = DDSCAPS_PRIMARYSURFACE | DDSCAPS_FLIP | DDSCAPS_COMPLEX; ddsd_primary.dwBackBufferCount = 1; hres = lpDD->CreateSurface(&ddsd_primary, &lpDDSPrimary, NULL); if(hres != DD_OK) MessageBox(hwnd, "CreateSurface failed in CDirectXFunctions::DirectDrawInit for lpDDSPrimary", "Error:DD006", MB_OK); //Back Buffer DDSURFACEDESC2 ddsd_backbuffer; ZeroMemory(&ddsd_backbuffer, sizeof(ddsd_backbuffer)); ddsd_primary.dwSize = sizeof(DDSURFACEDESC2); ddsd_primary.dwFlags = DDSD_CAPS; ddsd_primary.ddsCaps.dwCaps = DDSCAPS_BACKBUFFER; hres = lpDD->CreateSurface(&ddsd_primary, &lpDDSBackBuffer, NULL); if(hres != DD_OK) MessageBox(hwnd, "CreateSurface failed in CDirectXFunctions::DirectDrawInit for lpDDSBackBuffer", "Error:DD009", MB_OK); //Attatching back buffer ddscaps.dwCaps = DDSCAPS_BACKBUFFER; hres = lpDDSPrimary->GetAttachedSurface(&ddscaps, &lpDDSBackBuffer); if(hres != DD_OK) MessageBox(hwnd, "GetAttachedSurface failed for lpDDSPrimary in CDirectXFunctions::DirectDrawInit", "Error:008", MB_OK); I always get both error messages when I run this program, and it''s only for the back buffer. is there a function I can call that will creat the primary and back buffers at the same time and assigns pointers? I remember something about that in a tutorial I once read, but I''m not sure about that? Also, is my error notification code OK? And is using the same HRESULT variable for every one of my tests OK?

Well, I did a little digging, and the error returned when I try to get the attatched surface is DDERR_NOTFOUND which means that the requested item is not found. So... what do I do about that?

Here''s the code I use.

DDSURFACEDESC2 ddsd;ZeroMemory(&ddsd,sizeof(ddsd));ddsd.dwSize = sizeof( ddsd );ddsd.dwFlags = DDSD_CAPS | DDSD_BACKBUFFERCOUNT;ddsd.ddsCaps.dwCaps = DDSCAPS_PRIMARYSURFACE | DDSCAPS_FLIP | DDSCAPS_COMPLEX;ddsd.dwBackBufferCount = 1;lpDD->CreateSurface( &ddsd, &lpDDSPrimary, NULL );DDSCAPS2 ddscaps;ZeroMemory(&ddscaps,sizeof(ddscaps));ddscaps.dwCaps=DDSCAPS_BACKBUFFER;lpDDSPrimary->GetAttachedSurface(&ddscaps,&lpDDSBack);

Thanks, I''ll try that. And BTW, thanks for replying at such an ungodly hour of the night I''ll get back to you to see if it worked.

(The only thing I see diferent is that I didn''t ZeroMemory the ddscaps, something I always do (initilize to zero EVERYTHING kids, it saves SO MUCH OF A HEADACHE!!!))

It worked!!! YES!!! Now I can finaly continue with my programming
