CWndClassInfo::pWndProc
Points to the window procedure of an existing window class.
WNDPROC pWndProc;
Заметки
CWndClassInfo uses pWndProc only when you include the DECLARE_WND_SUPERCLASS macro in your class definition. In this case, CWndClassInfo registers a window class that is based on an existing class but uses a different window procedure. The existing window class's window procedure is saved in pWndProc. For more information, see the CWndClassInfo overview.
