IWMPNetwork::receivedPackets 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 It has been superseded by MediaPlayer.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 receivedPackets property gets the number of packets received.

Syntax

public System.Int32 receivedPackets {get; set;}

Public ReadOnly Property receivedPackets As System.Int32

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.

Examples

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.

// 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 packets may be arriving.
    switch (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();
            break;

        // If WMPPlayState is Playing or Buffering then set the timer interval and start the timer.
        default:
            timer.Interval = 1000;
            timer.Start();
            break;
    }
}

private void UpdateReceivedPackets(object sender, EventArgs e)
{
    receivedPacketsLabel.Text = ("Packets received: " + player.network.receivedPackets.ToString());
}

' 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
