The GetLongestPlayPosition method retrieves the longest play position of the object. The object must be a music file on the media device.
Syntax
HRESULT GetLongestPlayPosition(
DWORD* pdwLongestPos
);
Parameters
pdwLongestPos
[out] Pointer to a double word containing the longest play position of the object, in milliseconds.
Return Values
If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.
| Return code | Description |
| E_INVALIDTYPE | The object is not a valid playable file. |
| WMDM_E_NOTSUPPORTED | This object cannot report longest play position. |
| E_FAIL | An unspecified error occurred. |
Remarks
The object must be an audio data file. For all other object types, this function returns E_INVALIDTYPE.
The value returned in pdwLongestPos is specified in milliseconds. The last play position changes when either the user presses Play on the media device, or when an application invokes the IMDSPDeviceControl::Play method and that play exceeds the position of the last longest play position.
