IWMPNetwork.receivedPackets (VB and C#)

The receivedPackets property gets the number of packets received.

Property Value

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

Remarks

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

Example Code

The following example uses receivedPackets to display the number of packets received. The information is displayed 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 UpdateReceivedPackets(ByVal sender As Object, ByVal e As System.EventArgs) Handles timer.Tick

    receivedPacketsLabel.Text = ("Packets received: " + player.network.receivedPackets.ToString())

End Sub
