The first structure member, dwSize, should be set to the size of the structure, in bytes, before you use it.
If you are setting new color controls, set dwFlags to a combination of the appropriate flags to indicate which of the other structure members contain valid data that you have set.
The remaining DDCOLORCONTROL structure members can contain values that describe the brightness, contrast, hue, saturation, sharpness and gamma, and whether color is used.
