currently log in the database to log off. Is this possible? Any tips or

Typical method is to have a form that is always open check for an entry in a
table at set intervals (say once a minute). Normally this table would be empty,
but when you want people to exit the app you put a message into the table and
then next time the interval passes your timer code sees the entry and displays
it in another form. That form has a timer event of its own (say five minutes)
after which it closes the app down if the user hasn't already done so.

This is imperfect because if a user has a dialog open then no code will execute
until that dialog is closed (including the timer methods used for your message).
