MFC 9.0 类图

The Version 9.0 Feature Pack adds new classes to the Microsoft Foundation Class Library. New classes are indicated with a star. Managers, Control Support and Helper classes all provide logical and data support for individual controls or groups of controls. Managers have the word "Manager" in their name. They typically aggregate and coordinate functionality that would otherwise be handled by individual classes. Control SUpport classes usually provide logical and data support for individual controls.
