Re: multi threading/tasking?

I've been asked to write a server application specifically in VFP that opens a port and listens for one line strings from clients. These strings contain info that is used in lookups and calculations on a centrals database or databases (not all the specs are available yet) and then a response one line string is sent back to the client.

I was also told to use Socket Wrench to facilitate listening on the port, instigating sockets and reading and sending the strings. My biggest concern is that this server will be receiving strings non-stop from multiple clients and I can only assume many will come in at the same time.

I've never written a program that could handle multiple conversations. I've never written a program that used TCP/IP
I've only written 2 small VFP programs and none used Socket Wrench.

I'm a long time programmer but I've been writing stand alone programs using VB4 and DOS based Clipper. I'm fighting a seemingly huge learning curve. And I've got to figure this out.

I'll keep reading. Right now I have a tiny program that listens to a port accepts the connection from 1 client and echo's back any string that it's sent. Written in VFP.

Yes, I was talking about TCP/IP. I'll look over the references you gave me. Thank you, I appreciate your help. 
Well, TCP/IP is the protocoll used in the internet,
but it's not exclusively used there. You can also have
a LAN configured to use the TCP/IP protocoll.

You may have rang other peoples bells if you
would have been more specific and used terms
like "distributed application", "fat client" or at
least "internet".

I'm not sure what you need to achieve right now,
but the west-wind web page covers many different
solutions of which one should fit your needs.

Bye, Olaf.
