IWMPControls::fastForward method

[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 It has been superseded by MediaPlayer.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

public void fastForward();

Public Sub fastForward()
Implements IWMPControls.fastForward

Parameters

This method has no parameters.

Return value

This method does not return a value.

Remarks

The fastForward method plays the clip at five times the normal speed. Calling fastForward is equivalent to specifying 5.0 for the rate by setting the IWMPSettings.rate property. 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, pass the System.String value "FastForward" to the IWMPControls.isAvailable property (the IWMPControls.get_isAvailable method in C#).

Examples

The following example uses fastForward to fast-forward the current media item in response to the Click event of a button. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player.

private void fastForwardButton_Click(object o, System.EventArgs args)
{
    // To get all of the available functionality of the player controls, cast the
    // value returned by player.Ctlcontrols to a WMPLib.IWMPControls3 interface. 
    WMPLib.IWMPControls3 controls = (WMPLib.IWMPControls3)player.Ctlcontrols;

    // Check first to be sure the operation is valid.
    if (controls.get_isAvailable("fastForward"))
    {
        controls.fastForward();
    }
}

Public Sub fastForwardButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles fastForwardButton.Click

    ' To get all of the available functionality of the player controls, Dim the
    ' value returned by player.Ctlcontrols as a WMPLib.IWMPControls3 interface. 
    Dim controls As WMPLib.IWMPControls3 = player.Ctlcontrols

    ' Check first to be sure the operation is valid.
    If (controls.isAvailable("fastForward")) Then

        controls.fastForward()

    End If

End Sub
