Direct Chat Over Internet

[GermanDM]

Hi there, I am trying develope an internet chat application in C#.Net using Visual Studio 2005. I am struggling succeeding in this and basically ended up creating a network chat app. What i want to do is create an app that direct chats over the internet (like on a network chat). only my friend and myself will use it so no rooms or anything is needed its just a plain direct chat over the net.peer 2 peer like. I know the using of sockets or remoting but everywhere i look it all just goes down to an tcp/ip chat. Could anyone please help me with this or direct me somewhere where i can get help please? Kind Regards Deon

Im in a private network and my friend will be in a public network. hmmmm i guess firewalls will be a problem ouch. any suggestions maybe? im so confused and i know this is not alot of code it only has to be the most simplest app which sends text like p2p. i have some code i you want to take a look at it and maybe direct me from there. Thanks alot

If neither of you has a static ip then you'll need a web service to keep track of the ip-s for peer discovery, even if the app will be used by only the two of you.

You do know what TCP/IP means? it means Transmission Control Protocol over Internet Protocol. Which should give you a clue to how data is transmitted over the internet.
