Manages user interface commands.
This interface provides methods and properties that manage user interface commands. ICommandUI is similar to CCmdUI Class, except that ICommandUI is used for MFC applications that interoperate with .NET components.
ICommandUI is used within an ON_UPDATE_COMMAND_UI handler in an ICommandTarget-derived class. When a user of an application activates (selects or clicks) a menu, each menu item is displayed as enabled or disabled. The target of each menu command provides this information by implementing an ON_UPDATE_COMMAND_UI handler. For each of the command user interface objects in your application, use the Properties window to create a message-map entry and function prototype for each handler.
