IWMDMObjectInfo::GetLongestPlayPosition method (mswmdm.h)

The GetLongestPlayPosition method retrieves the longest play position of the file. The file must be an audio file on the media device.


HRESULT GetLongestPlayPosition(
  [out] DWORD *pdwLongestPos


[out] pdwLongestPos

Pointer to a DWORD specifying the longest play position of the object, in milliseconds.

Return value

The method returns an HRESULT. All the interface methods in Windows Media Device Manager can return any of the following classes of error codes:

  • Standard COM error codes
  • Windows error codes converted to HRESULT values
  • Windows Media Device Manager error codes
For an extensive list of possible error codes, see Error Codes.


The object must be an audio data file. For all other object types, this function returns E_INVALIDTYPE.

The last play position changes when either the user starts playing a file on the media device, or when an application invokes the IWMDMDeviceControl::Play method and that play exceeds the position of the last longest play position.
