Remarks

If the broadcast publishing point is stopped and you call the StartArchive method before calling IWMSBroadcastPublishingPoint.Start, the server automatically starts the publishing point.

Example Code

Imports Microsoft.WindowsMediaServices.Interop
Imports System.Runtime.InteropServices

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
    ' point
    BCPubPoint.StopArchive()

Catch excCom As COMException
    ' TODO: Handle COM exceptions.
Catch exc As Exception
    ' TODO: Handle errors.
Finally
    ' TODO: Clean-up code goes here.
