How You Can Customize Your Windows Application

As shown above, the Microsoft Foundation Classes supply a WinMain function that provides several standard Windows actions for you:

Windows application and instance initialization.

Registration of several standard window classes.

A message loop.

The Microsoft Foundation Classes also supply several ways to customize or override the standard facilities and behavior. You can:

Write your own WinMain function and substitute it at link time for the WinMain provided by the Microsoft Foundation Classes.

Call a global AfxRegisterWndClass function to register your own window classes.

Override member functions such as InitApplication, InitInstance, OnIdle, Run, and ExitInstance in your derived application class.

Make your program a Multiple Document Interface (MDI) application.

Add dialog boxes, menus, and accelerators.
