CWinAppEx handles the application state, saves the state to the registry, loads the state from the registry, initializes application managers, and provides links to those same application managers.

Remarks

Much of the functionality provided by the MFC framework depends on the CWinAppEx class. You can incorporate the CWinAppEx class into your application in one of two ways:

Construct a CWinAppEx class in the main thread.
Derive the main application class from CWinAppEx.

After you incorporate CWinAppEx into your application, you can initialize any one of the application managers. Before you use an application manager, you must initialize it by calling the appropriate initialize method. To obtain a pointer to a specific manager, call the associated get method. The CWinAppEx class manages the following application managers: CMouseManager Class, CContextMenuManager Class, CKeyboardManager Class, CUserToolsManager Class, and CMenuTearOffManager Class.
