This is a login application like others, using MS Access with the login and password of the users. But the problem is that i want that two user with the same login can´t acess at the same time. My problem is when the user get out the application (closing the browser or going to another page). I tried the Sessio_OnEnd to update a flag in a table but i isnt working. Can you help me? Forgive my poor (brazilian) english.
