I'm trying to implement some simple app which manages a list of user, and calling them, using call-back functions.
The idea is simple:
There is a server which have an interface on him. Between the client and the server, there is another tier. This tier is the login server, which implements the interface, and Logs-in the user.
The problem begins when I'm using the call-back functions of the interface, for calling the user (client).
If the user decides to pop-up a msgbox, my server gets stuck.
I think the solution is multithreading, but I have no idea, how this can be done.
I'd appriciate help with or w/o source code.
