IWMPEvents interface (wmp.h)
[The feature associated with this page, Windows Media Player SDK, is a legacy feature. It has been superseded by MediaPlayer. MediaPlayer has been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer instead of Windows Media Player SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The IWMPEvents interface provides events that originate from the Windows Media Player control. An embedding program can respond to these events. The events exposed by IWMPEvents are also exposed by the _WMPOCXEvents interface.
In addition to the methods inherited from IUnknown, the IWMPEvents interface exposes the following methods.
