IWMPControls::fastForward 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 It has been superseded by MediaPlayer.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 fastForward method starts fast play of the media item in the forward direction.

Syntax

HRESULT fastForward();

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK
The method succeeded.

Remarks

The fastForward method plays the clip back at five times the normal speed. Calling fastForward is equivalent to specifying 5.0 for the rate through the IWMPSettings::put_rate method. If the rate is subsequently changed, or if IWMPControls::play or IWMPControls::stop is called, Windows Media Player will cease fast forwarding.

The fastForward method does not work for live broadcasts and certain media types. To determine whether you can fast forward in a clip, call the IWMPControls::get_isAvailable method and pass in the BSTR value "FastForward".

Requirements
