Example

Imports Microsoft.WindowsMediaServices.Interop

Private Sub BeginArchive()

    ' Declare variables.
    Dim Server As WMSServer
    Dim BCPubPoint As IWMSBroadcastPublishingPoint
    Dim Plugin As IWMSPlugin

Try
    ' Create the WMSServer object.
    Server = New WMSServer()

    ' Retrieve the sample broadcast publishing point.
    BCPubPoint = Server.PublishingPoints("Sample_Broadcast")

    ' Stop the publishing point.
    BCPubPoint.Stop()

    ' Set the publishing point path.
    BCPubPoint.Path = "C:\WMPub\WMRoot\Serverside_Playlist.wsx"

    ' Retrieve the WMS Archive Data Writer Plug-in. This is the 
    ' default archive plug-in for the publishing point.
    Plugin = BCPubPoint.BroadcastDataSinks("WMS Archive Data Writer")

    ' Make sure the plug-in is enabled. By default, it is not
    ' enabled.
    If Plugin.Enabled = False Then
        Plugin.Enabled = True
    End If

    ' Restart the publishing point and begin archiving.
    BCPubPoint.StartArchive()

    ' Archive for 10 seconds.
    System.Threading.Thread.Sleep(10000)

    ' Stop archiving. This does not stop the publishing

    BCPubPoint.StopArchive()

Catch excCom As COMException
