Creation of a Multicast Station Sample

This sample demonstrates how you can:

• Embed the Windows Media Station control in an HTML page.
• Use the Microsoft® Visual Basic® Scripting Edition (VBScript) programming language to invoke the Connect method exposed by the Windows Media Station control to access the server that is running Windows Media Services.
• Create a Windows Media station.
• Create a stream.
• Assign the stream to the station.
