Go to the assertion statement and see what it's telling you (for example, an assertion may be checking whether a CWnd has a valid HWND associated with it). Next, follow the call stack backwards from the point where the assertion was triggered and find out which one of your calls led to the assertion and figure out why it triggered it (for example, a common mistake I've seen is people trying to access window controls before the window has even been created, like in a CWnd constructor).
