IWMPNetwork.recoveredPackets (VB and C#)

The recoveredPackets property gets the number of recovered packets.

  

Property Value

A System.Int32 that is the number of recovered packets.

Remarks

Each time playback is stopped and restarted, this property is reset to zero. The value is not reset if playback is paused.

This property gets valid information only during run time when the URL for playback is set by using the AxWindowsMediaPlayer.URL property. The value will be zero when using the HTTP protocol, which is lossless.

Example Code

The following example uses recoveredPackets to display the number of recovered packets in a label, in response to the PlayStateChange Event. The example uses a timer with a 1-second interval to update the display. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player.

  
' Create an event handler for the PlayStateChange event.
Public Sub player_PlayStateChange(ByVal sender As Object, ByVal e As AxWMPLib._WMPOCXEvents_PlayStateChangeEvent) Handles player.PlayStateChange

    ' Test whether packets may be arriving.
    Select Case e.newState

    ' If WMPPlayState is Stopped, Paused, ScanForward, ScanReverse, Waiting, MediaEnded
    ' or Transitioning then stop the timer. 
        Case 1
        Case 2
        Case 4
        Case 5
        Case 7
        Case 8
        Case 9
            timer.Stop()

        ' If WMPPlayState is Playing or Buffering then set the timer interval and start the timer.
        Case Else
            timer.Interval = 1000
            timer.Start()

    End Select

End Sub

Public Sub UpdateRecoveredPackets(ByVal sender As Object, ByVal e As System.EventArgs) Handles timer.Tick

    recoveredPacketsLabel.Text = ("Packets recovered: " + player.network.recoveredPackets.ToString())

End Sub

// Add a delegate for the PlayStateChange event.
player.PlayStateChange += new AxWMPLib._WMPOCXEvents_PlayStateChangeEventHandler(player_PlayStateChange);

// Create an event handler for the PlayStateChange event.
private void player_PlayStateChange(object sender, AxWMPLib._WMPOCXEvents_PlayStateChangeEvent e)
{
    // Test whether content is playing. 
    if (e.newState == 3)
    {
        // Start the timer. Update the display every 10 seconds.
        timer.Interval = 10000;
        timer.Start();
    }
    else
    {
        // Not playing; stop the timer.
        timer.Stop();
    }
}

private void UpdateRecoveredPackets(object sender, EventArgs e)
{
    recoveredPacketsLabel.Text = ("Packets recovered: " + player.network.recoveredPackets.ToString());
}
