HOWTO: How to Set Up and Use 320x200x8 and 320x240x8 DDraw Modes

MORE INFORMATION

Example Code to Set Up Mode 13 or Mode X

LPDIRECTDRAW            lpDD;           // DirectDraw object
LPDIRECTDRAWSURFACE     lpDDSPrimary;   // DirectDraw primary surface
LPDIRECTDRAWSURFACE     lpDDSBack;      // DirectDraw back surface
DDSCAPS                 ddscaps;
DDSURFACEDESC           ddsd;
HRESULT                 hResult;

// Create the main DirectDraw object

hResult = DirectDrawCreate( NULL, &lpDD, NULL );

if (DD_OK != hResult)
{
    // Handle error
}

// Get exclusive mode

hResult = lpDD->SetCooperativeLevel(hWnd, DDSCL_EXCLUSIVE |
        DDSCL_FULLSCREEN | DDSCL_ALLOWMODEX);

if (DD_OK != hResult)
{
    // Handle error
}

// Use mode 13

hResult = lpDD->SetDisplayMode( 320, 200, 8 );

if (DD_OK != hResult)
{
    // handle error
}
				

Example Code to Create a Primary Surface with One Back Buffer

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;

// Create a primary surface with one back buffer

hResult = lpDD->CreateSurface( &ddsd, &lpDDSPrimary, NULL );

if (DD_OK != hResult)
{
    // Handle error
}

// Get a pointer to the back buffer

ddscaps.dwCaps = DDSCAPS_BACKBUFFER;
hResult = lpDDSPrimary->GetAttachedSurface(&ddscaps,  &lpDDSBack);

if (DD_OK != hResult)
{
    // Handle error
}
