    DirectX surface question

    How do you fill a surface (LPDIRECTDRAWSURFACE7) with only one color? It seems like a waste of memory to create a 640x480 bitmap containing one color

    Code:
    DDBLTFX ddbltfx;
        ZeroMemory( &ddbltfx, sizeof(ddbltfx) );
        ddbltfx.dwSize      = sizeof(ddbltfx);
        ddbltfx.dwFillColor = dwColor;
    
     m_pddsBackBuffer->Blt( NULL, NULL, NULL, DDBLT_COLORFILL, &ddbltfx );
    Taken directly from the MS helper classes and assumes you're using DirectDraw. dwColor is the colour (suprise, suprise). Just flip your backbuffer (m_pddsBackBuffer).
