This class is a base class that implements the IDispatch interface for use in a dual interface. A dual interface provides Automation and custom interface access to an interface.

CMediaControl and CMediaPosition (and other dual-interface support classes) are derived from this class or have members that are instances of this class.

For more information about the IDispatch methods, see the COM documentation included with the Microsoft Platform Software Development Kit (SDK).
