One easy way is to use CSocketFile. CSocketFile acts in most
cases just like a normal CFile, so you can use Read/Write
directly from/to it. You can even connect a CArchive to it.

The code below needs error-handling, and in the server you
really should start a thread for each incoming connection.
(Otherwise the connection will block others.)

---[client]---
CString server = "10.0.0.1";
int port = 6789;
CSocket sock;
sock.Create();
sock.Connect(server, port);
CSocketFile sfile(&sock);
...
(Do you stuff here. Read/Write to sfile!)
...
sfile.Close();
sock.Close();
---[client]---


---[server]---
int port = 6789;
CSocket sock;
sock.Create(port);
sock.Listen();
CSocket* client;
while (some_condition)
{
   client = new CSocket;
   sock.Accept(*client);
   CSocketFile sfile(client);
   ...
   (Do your stuff here. Start a thread, read/write)
   ...
   sfile.Close();
   client->Close();
   delete client;
}
sock.Close();
---[server]---
