CMediaPosition Class

The CMediaPosition 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.

Member Functions

CMediaPosition

Constructs a CMediaPosition object.

Implemented INonDelegatingUnknown Methods

NonDelegatingQueryInterface

Returns a specified reference-counted interface.

Implemented IDispatch Methods

GetIDsOfNames	Maps a single member and an optional set of parameters to a corresponding set of integer dispatch identifiers, which can be used during subsequent calls to the CMediaPosition::Invoke member function.
GetTypeInfo	Retrieves a type-information object, which can retrieve the type information for an interface.
GetTypeInfoCount	Retrieves the number of type-information interfaces provided by an object.
Invoke	Provides access to properties and methods exposed by an object.
