Root Class: CObject

Most of the classes in the Microsoft Foundation Class Library are derived from a single base class at the root of the class hierarchy. CObject provides a number of useful capabilities to all classes derived from it, with very low overhead. For more information about CObject and its capabilities, see CObject Class Topics in Visual C++ Programmer's Guide.
