I try to use this code.... DDSURFACEDESC2 ddsd; ddrval = lpDD->CreateSurface( &ddsd, &lpDDSPrimary, NULL ); and vc++6 says... ''CreateSurface'' : cannot convert parameter 1 from ''struct _DDSURFACEDESC2 *'' to ''struct _DDSURFACEDESC *'' this is the only thing stopping my app to work. Its probably very simple but i cant see anything wrong. Please help as i am desperate

This will fix it, but not what you want probably:

DDSURFACEDESC2 ddsd; 

Becomes...

DDSURFACEDESC ddsd; 

Rather than do that though, show us the first part of your initialization code. You probably aren''t using the right version of DirectDraw.

the full code for initialization is...

DDSURFACEDESC2 ddsd;
DDSCAPS2 ddscaps;
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;
ddrval = lpDD->CreateSurface( &ddsd, &lpDDSPrimary, NULL );
if (ddrval!=DD_OK) {
ErrStr=Err_CreateSurf;
return FALSE;
}

ive already been told to change DDSURFACEDESC2 to DDSURFACEDESC and that didnt help either.

thanks
