This isn't quite what you want, but it may be of some help (if it works ).

You could make a DC:

HDC hdcImage;
hdcImage = CreateCompatibleDC( NULL );

Then get a DC to the DDraw surface:

HDC hdc;
lpDDSBitmap->GetDC( &hdc );

Now BitBlt into hdcImage:

DDSURFACEDESC2 ddsd;
ddsd.dwSize = sizeof( ddsd );
ddsd.dwFlags = DDSD_HEIGHT | DDSD_WIDTH;
lpDDSBitmap->GetSurfaceDesc( &ddsd );

BitBlt( hdcImage, 0, 0, ddsd.dwWidth, ddsd.dwHeight, hdc, 0, 0, SRCCOPY );

And, of course, release the DC:

lpDDSBitmap->ReleaseDC( hdc );

I am making a level editor in windows for a Direct Draw tiled game. I use a windowed direct draw surface as the view, and load all my images into direct draw surfaces. I would like to create a modeless dialog box that the user selects tiles from, but I can't draw direct draw surfaces to a dialog box. The only way to draw the tile images to the dialog that I can think of is to use DIBs, but I'd like to avoid re-reading the bmp files into DIB classes... I was wondering if anyone knows a way to draw a DIB in windows using the data from a direct draw surface. I was thinking that I could lock the surface and use the lpImage pointer as the data when drawing a DIB, or something like that, but it doesn't work... Any ideas?
