Rene,
I did something similar to this some years ago using C whereas my application contained some 'dummy' data which was then stored in the .exe file. My application then used this area in the exe to keep a log of users. Each time a user ran the app, every few seconds the app would place the time into this area in the exe - when another user comes along, the slots are checked for open spaces and, if none found, would check to see if any have an out-of-date time slot and use one up if it finds it. I think that this idea could be modified to work with VFP in some way.
