VB6 connectionless UDP multicast

[tthoele]

Greetings!

I am working on an application where I need to send a large dataset to multiple clients on a streaming basis.

I am implimenting a TCP connection from each client to the server to register the clients, as well as for the client to send data to the server.

I would like to send out the dataset on a UDP port, and have all clients listen to the port (different from the TCP port).

I have found several commercial controls to do this, but I'm on a budget (none). Any ideas for a FREE implementation?

Thanks,
Troy

The standard Winsock control supports UDP. There is some sample code in VBHelp

I'm having thermonuclear meltdown on this one...

I tried implimenting the winsock control using UDP, but it is implemented as a peer to peer. I cant figure out how to make it do multicast. the two values it asks for is remotehost and remote port.

Do you have a link to an example? When do I use the multicast address? Where do I put in the multicast group?
