.gif "Aa451554.cutil04(en-us,MSDN.10).gif")
This class is a base class that handles the IDispatch methods of the dual-interface IMediaPosition. It leaves the properties and methods as pure virtual.
The CMediaPosition::GetIDsOfNames, CMediaPosition::GetTypeInfo, CMediaPosition::GetTypeInfoCount, and CMediaPosition::Invoke methods are standard implementations of the IDispatch interface using the CBaseDispatch class (and a type library) to parse the commands and pass them to the pure virtual IMediaPosition methods.
