IWMPNetwork.sourceProtocol (VB and C#)

The sourceProtocol property gets the source protocol used to receive data.

Property Value

A System.String that is the name of the source protocol.

Example Code

The following code example uses sourceProtocol to display the source protocol used to receive data. The information is displayed in a label, in response to the PlayStateChange Event. 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

    ' Display the network source protocol when the player is playing by testing for a 
    ' play state enum value of WMPLib.WMPPlayState.wmppsPlaying which equals 3.
    If (e.newState = 3) Then

        sourceProtocolLabel.Text = ("Source protocol: " + player.network.sourceProtocol)

    End If

End Sub

{
    // Display the network source protocol when the player is playing by testing for a 
    // play state enum value of WMPLib.WMPPlayState.wmppsPlaying which equals 3. 
    if (e.newState == 3) 
    {
