In my app I have a login procedure and everytime someone login I update my login table and this tell me how many users are login and I also have a logout procedure that update the login table, this will work well in a perfect world, where I see a problem is if the users computer shutdown prematurely, if this happen it would not update my login table, so the login count would be off.

I need some ideals on how many users are login to the application.

Thanks Randy
