Handling minimisation in Fullscreen Win32 OpenGL

Question

Hi, I'm trying to create a fullscreen application using Win32 and OpenGL. I change the resolution using EnumDisplaySettings and ChangeDisplaySettings and the OpenGL functions work fine. On its WndProc I handle WM_ACTIVATEAPP and detect when the user switched focus to another window, then I minimize the application's window. When the window is maximized again, the window doesn't display properly at all. What could I include to make the application work even after minimizing?

From the question I cannot still say what you are missing and what you already have. Refer to the http://nehe.gamedev.net/. There is a section Opengl base code to setup a window in full screen and switch back to window mode. See if you can get something from there.
