When this assertion is being thrown, it typically means that you're making a call into the MFC framework to a GUI element that doesn't exist yet (such as a window that hasn't been created yet). Look at the call stack to figure out what call you made and to what. If you post some of the code I can probably guide you into how to fix it.
