Mario,

Here's pure FoxPro code to determine the number of colors.

FUNCTION NumColors
  DECLARE INTEGER GetDC IN Win32API;
    INTEGER hWnd
  DECLARE INTEGER GetDeviceCaps IN Win32API;
    INTEGER hDC, INTEGER nIndex
  DECLARE INTEGER ReleaseDC IN Win32API;
    INTEGER hWnd, INTEGER hDC
  LOCAL lnresult, lnhDC, lnplanes, lnpixels
  lnresult = 0
  lnhDC = GetDC(0)
  IF lnhDC > 0
    lnplanes = GetDeviceCaps(lnhDC, 14) && 14 is the number of planes
    lnpixels = GetDeviceCaps(lnhDC, 12) && 12 is the bits per pixel
    lnresult = 2 ^ (lnplanes * lnpixels)
    = ReleaseDC(0, lnhDC)
  ENDIF
  RETURN lnresult
ENDFUNC
