Hi, I'm having a problem with setting a palette for the primary surface with the function: IDirectDrawSurface7::SetPalette. I'm running using DDSCL_NORMAL in a window. I have a feeling that the problem may be somewhere else in the set up routine, so here's the whole thing.

BOOL InitDirectDraw ()
#define DDIERR(x) {
MessageBox(hwnd,x,"DirectDraw Error!",MB_OK|MB_ICONEXCLAMATION);return FALSE;}

// Create the main DirectDraw object

if (FAILED (DirectDrawCreateEx (NULL, (void**)&lpdd, IID_IDirectDraw7, NULL)))
  DDIERR ("Unable to create the main DirectDraw object!");

// Set the cooperative level

if (FAILED (lpdd->SetCooperativeLevel (hwnd, DDSCL_NORMAL)))
  DDIERR ("Unable to set the cooperative level to DDSCL_NORMAL!");

// Create the primary surface

ZeroMemory (&ddsd, sizeof(ddsd));
ddsd.dwSize = sizeof(ddsd);
ddsd.dwFlags = DDSD_CAPS;

if (FAILED (lpdd->CreateSurface (&ddsd, &lpddsPrimary, NULL)))
  DDIERR ("Unable to create the primary surface!");

// Create a clipper for the primary surface

if (FAILED (lpdd->CreateClipper (0, &lpddClipper, NULL)))
  DDIERR ("Unable to create the clipper!");
if (FAILED (lpddClipper->SetHWnd (0, hwnd)))
  DDIERR ("Unable to set the clipper to the window!");
if (FAILED (lpddsPrimary->SetClipper (lpddClipper)))
  DDIERR ("Unable to set the primary surface clipper!");

// Initialize a palette

for (int i = 0; i < 256; i++)
  pal[i].peRed = (BYTE) (((i >> 5) & 0x07) * 255 / 7);
  pal[i].peGreen = (BYTE) (((i >> 2) & 0x07) * 255 / 7);
  pal[i].peBlue = (BYTE) (((i >> 0) & 0x03) * 255 / 3);
  pal[i].peFlags = (BYTE) 0;

// Create and set the palette

if (FAILED (lpdd->CreatePalette (DDPCAPS_8BIT|DDPCAPS_ALLOW256,
  pal, &lpddPal, NULL)))
  DDIERR ("Unable to create the palette!");

// ** This is where it returns DDERR_INVALIDPIXELFORMAT! **

if (FAILED (lpddsPrimary->SetPalette (lpddPal)))
  DDIERR ("Unable to set the palette!");
