I'm thinking about a licence-mechanism for my app. I want to licence the
number of simultaneous connections, for example you have a
5-User-Licence, then 5 users can work simultaneous on the db. The
problem is, when the pc of a user crashes, then he is marked in the db
as logged in, but he isn't. Therefore the client tells every 10 minutes
the server I'm alive and when the client crashes, the server recognizes
after 10 minutes, the client is dead and marks the user as logged out.
But therefore I need a task, that checks all 10 minutes, if the user is
alive. How can I realize this with IB ?
