IHi all, I have the following requirement, I need to start my app after a user logs in, it does some checks if they registered their hours from the day before, if yes then close app if no present form where they can register their hours. All this I can ofcourse do, but how do I make it that they cannot do anything else unless they have registered their hours. Meaning they can not open any other program. Is this possible and if so how ?
