SetWinColor

NOT RECOMMENDED WITH THE APPEARANCE MANAGER

When the Appearance Manager is available and your application uses standard windows, the SetWinColor function is not recommended. SetWinColor sets a window color table structure which is now mostly ignored. Only the part identifier constant wContentColor in the value field of the ColorSpec structure is used. This constant produces the background color for the window's content region. Under Appearance, instead of the SetWinColor function, the window definition function determines what colors it will use.

If your are creating your own custom window definition functions, SetWinColor can still be used.
