IWMPMedia::durationString property

[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 It has been superseded by MediaPlayer.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 durationString property gets a string indicating the duration of the current media item in HH:MM:SS format.

This property is read-only.

Syntax

public System.String durationString {get;}

Public ReadOnly Property durationString As System.String

Property value

A System.String that is the duration.

Remarks

If this property is used with a media item other than the one specified in AxWindowsMediaPlayer.currentMedia, it may not contain a valid value. If the media item is less than an hour long, the hours portion of the return value is omitted.

Before using this property, you must have read access to the library. For more information, see Library Access.

Examples

The following example uses durationString to display the duration of the current media item as formatted text in a label. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player.

// Create an event handler for the OpenStateChange event.
private void player_OpenStateChange(object sender, AxWMPLib._WMPOCXEvents_OpenStateChangeEvent e)
{
    // Test whether the current media item is open.
    if (e.newState == (int)WMPLib.WMPOpenState.wmposMediaOpen)
    {
         // Display the formatted duration string in the label.
         mediaDuration.Text = player.currentMedia.durationString;
    }
}

' Create an event handler for the OpenStateChange event.
Public Sub player_OpenStateChange(ByVal sender As Object, ByVal e As AxWMPLib._WMPOCXEvents_OpenStateChangeEvent) Handles player.OpenStateChange

    ' Test whether the current media item is open.
    If (e.newState = 13) Then

        ' Display the formatted duration string in the label.
        mediaDuration.Text = player.currentMedia.durationString

    End If

End Sub
