The SetPlayLength method sets the maximum time, in milliseconds, that an object can be rendered regardless of its actual length.
Syntax
HRESULT SetPlayLength(
DWORD dwLength
);
Parameters
dwLength
[in] Double word containing the play length to set for the playable object.
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 with which this interface is associated is not a playable file or folder. |
| WMDM_E_NOTSUPPORTED | This device does not support setting play lengths. |
| E_FAIL | An unspecified error occurred. |
Remarks
If the value passed is greater than the total object length, dwLength is clipped to the length of the object minus the current play position minus one unit.
The value set for playable files is specified in milliseconds. The value is clipped to the total file length minus the current play offset. The play position can change either when the user presses Play on the media device, or when an application invokes the IWMDMDeviceControl::Play method.
