Property Description
BufferingTime Specifies and retrieves the amount of time that the plug-in buffers data before sending it along the data path.
NumProtocolsSupported Retrieves the number of networking protocols supported by the plug-in.
NumUDPPortRanges Retrieves the number of UDP/TCP port number ranges that can be used by the data source plug-in to receive data.
ProxyHostName Retrieves the name of the proxy server.
ProxyPassword Retrieves a Boolean value indicating whether a proxy password has been set for a particular protocol.
ProxyPort Retrieves the port number to use for a particular protocol to receive content from an upstream proxy server.
ProxySettings Retrieves an enumeration value indicating the proxy mode for a particular protocol.

TCPEnabled Retrieves a Boolean value indicating whether the data source plug-in can use TCP when selecting a streaming protocol.
UDPEnabled Specifies and retrieves a Boolean value indicating whether the data source plug-in can use UDP when selecting a streaming protocol.
UDPPortRangeLowerBound Retrieves the lower bound of a specific UDP port range.
UDPPortRangeUpperBound Retrieves the upper bound of a specific UDP port range.
Method Description
AddUDPPortRange Adds a range of UDP/TCP port numbers that can be used by the data source plug-in to receive data.
DeleteAllUDPPortRanges Removes all of the UDP/TCP port number ranges that can be used by the data source plug-in to receive data.

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

End Sub
