IWMPNetwork::sourceProtocol 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 It has been superseded by MediaPlayer.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 sourceProtocol property gets the source protocol used to receive data.

Syntax

public System.String sourceProtocol {get; set;}

Public ReadOnly Property sourceProtocol As System.String

Property value

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

Remarks

This property gets a zero-length string ("") when playing a CD or DVD.

Examples

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.

// 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)
{
    // 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) 
    {
        sourceProtocolLabel.Text = ("Source protocol: " + player.network.sourceProtocol);
    } 
}

' 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
