Re: Common CPP Classes for EventHandler Classes

Hello Mike,

a

We have the same needs. And we have develop some framework for simple
writing 'client', which can connect to a 'server' and a server, which
can communicate with may 'clients' at the same time.
This framework contains mechanism for managing connections and
messages between clients and server. Of course, this based on
CommonC++ classes.
In the near future I'll prepare this for comfortable using by othe
peoples and put it in public access.
