Hi all.
I'm writing a very simple instant messenger. I want to use WebServices as a proxy for users' messages. Windows application invokes a method in WebService, then WebService sends the message to each connected user. I don't know how to send the message from WebService and recive it on Windows application. How to do that I've got no experience with communication in the Internet.
I've got also the second problem. How to get an IP address of the user, who invokes WebService method I must have a list of IP addresses of clients.
I hope you'll help me.
Regards,
Wojtek
P.S.
Sorry for my Engilsh
