>How can I know what's the current number of colors allowed by the display adapter?
You can retrieve the number of color bits that a particular display uses by calling the GetDeviceCaps function, specifying BITSPIXEL as the second argument.
DECLARE Long ReleaseDC IN WIN32API Long HWND, Long HDC
DECLARE Long GetDC IN WIN32API Long HWND
DECLARE Long GetDeviceCaps IN WIN32API Long HDC, Long nIndex
lnHDC = GetDC(0)
cnBitsPixel = 12
lnBitsPixel = GetDeviceCaps(lnHDC, cnBitsPixel )
= ReleaseDC(0, lnHDC )
