Solution 1

There are endless samples of code available via Google: search for "VB.NET socket".

Well, not the only one (by far), and not the most recommended, in fact. Will you see my answer?

What do you mean "not the only one"? All I suggested was doing a Google search for the many possibilities that exist.

Sergey Alexandrovich Kryukov 16-Aug-12 12:50pm

I just mean that the level of socket API is only one of the few level one can use. You suggest to search in "VB.NET socket". It would leave out more straightforward TcpClient/TcpListener, and also remoting, WPF and some other things. Please see my answer to see what I mean...

dear sir,
i want to communicate over WAN not LAN,
the pc are at different networks, so how can i communicate ?

Richard MacCutchan 16-Aug-12 5:59am

Same issue, TCP/IP goes anywhere.

Sergey Alexandrovich Kryukov 16-Aug-12 12:50pm

This is irrelevant. Socket is socket, IP is IP.

No idea what you are talking about.

Sergey Alexandrovich Kryukov 16-Aug-12 13:01pm

If you look at comment structure, you will see that I address to Ravi. I say that the WAN vs. LAN issue is irrelevant to your answer, because socket API and IP "goes anywhere", as you say yourself. Sorry that I confused you; but actually I supported your own answer to Ravi's comment.

You can do it on different levels. Please see my overview of them in my past answers:
how i can send byte[] to other pc[^],
Communication b/w two Windows applications on LAN.[^].

Good luck,
