CWinAppEx::InitContextMenuManager
Visual Studio 2012
Initializes the CContextMenuManager object.
BOOL InitContextMenuManager();
If you call CWinAppEx::GetContextMenuManager, the default implementation of that method calls InitContextMenuManager.
If your application already has a context menu manager and you call InitContextMenuManager, your application will have an ASSERT failure. Therefore, you should not call InitContextMenuManager if you create a CContextMenuManager object directly. If you are not using a custom CContextMenuManager, you should use GetContextMenuManager to create a CContextMenuManager object.
