IWMSServer.ControlProtocols (Visual Basic .NET)

The ControlProtocols property retrieves an IWMSPlugins object containing a collection of control protocol plug-ins that can be used to interpret and respond to client requests.

Syntax

  IWMSPlugins = IWMSServer.ControlProtocols

Property Value

An IWMSPlugins object containing the collection of control protocol plug-ins.

Remarks

This property is read-only. Plug-ins included with Windows Media Services support the RTSP, HTTP, and MMS protocols.

The following system plug-ins can be accessed by using the ControlProtocols property.

Plug-in	Description
WMS HTTP Server Control Protocol	Enables a Windows Media server to communicate with clients by using the HTTP protocol.
WMS MMS Server Control Protocol	Enables a Windows Media server to communicate with clients by using the MMS protocol.
WMS RTSP Server Control Protocol	Enables a Windows Media server to communicate with clients by using the RTSP protocol.

In Windows Server 2008 operating systems, the MMS protocol is not supported, and Windows Media Services does not provide an MMS Server Control Protocol plug-in.

Example Code

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

Private Sub GetControlProtocols()

    ' Declare variables.
    Dim Server As WMSServer
    Dim Plugins As IWMSPlugins

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

    ' Retrieve a pointer to an IWMSPlugins interface
    ' containing control protocol plug-ins.
    Plugins = Server.ControlProtocols

Catch excCom As COMException
    ' TODO: Handle COM exceptions.

    ' TODO: Handle errors.
Finally
    ' TODO: Clean-up code goes here.
