IWMPEvents::PositionChange method (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 It has been superseded by MediaPlayer.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 PositionChange event occurs when the current playback position within the media item has been changed.

  [in] double oldPosition,
  [in] double newPosition
);

Parameters

Remarks
