I have a book called "C# Network Programming" by Richard Blum.
http://www.amazon.com/C-Network-Programming-Richard-Blum/dp/0782141765/ref=pd_bbs_sr_1/103-7799866-0219011?ie=UTF8&s=books&qid=1182196498&sr=1-1

I have been through it twice.

What I would like to do is to be able to pass simple text messages between multiple PC's across
the internet. A very simple IM application is what I'm envisioning.

So far I'v been unsucessful. I'm not sure if its a firewall issue or something else. Know where I can
get an example of this?

Thanks





>WinSock is the old API for the COM based model. In .Net there is not WinSock, but there is a System.Net.Sockets. Here is an excerpt from the docs:
>The System.Net.Sockets namespace provides a managed implementation of the Windows Sockets (Winsock) interface for developers who need to tightly control access to the network.
