I am getting an Access Violation error. I can''t figure what is actually causing the problem. According to the debugger this is the line which is stuffing up. pDDSPrimary->GetAttachedSurface(&ddsd.ddsCaps,&pDDSBack); Please help.... if you need more info just tell me what you need. Thanks in advance... -David

Step through it with the debugger.

Is pDDSPrimary NULL?
Is ddsd (surface description) filled in?

Looks like pDDSPrimary wasn''t created..

// CHRIS

Here is the rest of the initialization method.

        DirectDrawCreateEx(NULL,(void**)&pDD,IID_IDirectDraw7,NULL);	hr = pDD->SetCooperativeLevel(hWnd,			DDSCL_ALLOWMODEX  |			DDSCL_ALLOWREBOOT |			DDSCL_EXCLUSIVE   |			DDSCL_FULLSCREEN);				pDD->SetDisplayMode(Width,Height,Bpp,0,0);	memset(&ddsd,0,sizeof(ddsd));	ddsd.dwSize  = sizeof(ddsd);	ddsd.dwFlags = DDSD_CAPS | DDSD_BACKBUFFERCOUNT;		ddsd.dwBackBufferCount = 1;	ddsd.ddsCaps.dwCaps =   DDSCAPS_PRIMARYSURFACE |				DDSCAPS_COMPLEX |				DDSCAPS_FLIP;		pDD->CreateSurface(&ddsd,&pDDsPrimary,NULL);			ddsd.ddsCaps.dwCaps = DDSCAPS_BACKBUFFER;    pDDsPrimary->GetAttachedSurface(&ddsd.ddsCaps,&pDDsBack);

Why did you put "(void **)" in front of the pDD?
As which type did you declare pDD?
