Example Code

The following example illustrates how to retrieve an IWMSAdminNetworkDataSourcePlugin object.

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

Private Sub RetrieveObj()

    ' Declare variables.
    Dim Server As WMSServer
    Dim Plugin As IWMSPlugin
    Dim AdminNetDataSrc As IWMSAdminNetworkDataSourcePlugin

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

    ' Retrieve the plug-in to be configured.
    Plugin = Server.DataSources.Item("WMS Network Data Source")

    ' Retrieve the custom interface of the plug-in.
    AdminNetDataSrc = Plugin.CustomInterface

Catch excCom As COMException
