IWMPPlayer::put_fullScreen 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 It has been superseded by MediaPlayer.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 put_fullScreen method specifies a value indicating whether video content is played back in full-screen mode.

| Return code | Description |

The method succeeded. |
Remarks
For full-screen mode to work properly when embedding the Windows Media Player control, the video display area must have a height and width of at least one pixel. If the BSTR specified in IWMPPlayer::put_uiMode is set to "mini" or "full", the height of the control itself must be 65 pixels or greater to accommodate the video display area in addition to the user interface.
If the BSTR specified in IWMPPlayer::put_uiMode is set to "invisible", then specifying the VARIANT_BOOL to TRUE in IWMPPlayer::get_fullScreen raises an error and does not affect the behavior of the control.
During full-screen playback, Windows Media Player hides the mouse cursor when the VARIANT_BOOL retrieved from IWMPPlayer::get_enableContextMenu equals FALSE and the BSTR retrieved from IWMPPlayer::get_uiMode equals "none".
If the BSTR specified in IWMPPlayer::put_uiMode is set to "full" or "mini", Windows Media Player displays transport controls in full-screen mode when the mouse cursor moves. After a brief interval of no mouse movement, the transport controls are hidden. If the BSTR specified in IWMPPlayer::put_uiMode is set to "none", no controls are displayed in full-screen mode.
Note
Displaying transport controls in full-screen mode requires the Windows XP operating system.
If transport controls are not displayed in full-screen mode, then Windows Media Player automatically exits full-screen mode when playback stops.
