I''m kind of hoping to get answers on this question before I get too involved with my approach to the task. Which is chaning from window to Fullscreen. I''m looking for some opinions as to what might be the best approach. Changing the class members then redisplaying the window? Or creating a whole new window, one that is full size, and destroying the old one? The question stems from providing the user with options right at the beginning of the App. Thanks for your help, L- /***************************** No one has control -- control is just a fantasy.

Have a look at the DEVMODE struct and ChangeDisplaySettings function in MSDN.
