Windows allows several copies of the same program to run at the same time. Application initialization is conceptually divided into two sections: one-time application initialization that is done the first time the program runs, and instance initialization that runs each time a copy of the program runs, including the first time. The framework's implementation of WinMain calls this member function.
virtual BOOL InitInstance( );
