Does anyone have VB sample code of a server and client communicating using the UDP control with the Protocol set to IGMP?

My code works fine when using the Protocol set to UDP but when I try to use IGMP the client stops receiving and if I look at data received by the master it is a mixture of ASCII characters, I have tried to convert these from Unicode to a string without success.

IGMP isn't a transport protocol and as such doesn't facilitate the transfer of pure data. The IGMP protocol pretty much only handles the routing and notification to multicast-routers that a client has joined a multicast group as well as querying whether clients are still connected to multicast groups.
