The GenericClient object can be used to create any sort of client application
and the GenericServer object can be used to create any sort of server application.
This is an API only winsock wrapper setup as an active X dll. It will hide the difficulties
in the Winsock for you and it stimulate developing in an object oriented way.
You will probably write your own protocol handler (like SMTP, POP or ...) using the OnDataArive event.
The bennefit of this library is that it uses very litle memory (compared to the inet control),
it's very fast, you do not need a form and its very easy to create multiple instances.
I tested it with 4 servers and 400 clients on 1 machine.

A demo is included that show you how to make a simple chat application.
Also a demo is available that shows you how to do port mapping.
If you want more samples, then have a look at tha SMTP and POP library at https://www.evict.nl/open_source.asp

2 years ago I posted an earlier version of this code here to VBC. This submition has some bug fixes, a lot of improvements for stimulating object oriented programming and there is a portmapper demo added.
