I need to know how can I make trial(demo) version of my program. Normally people use date & time to do it. But if user will change his system date I guess it will not work. I need to know the best way of making trial version which will work only 7 or 15 or 30 days. Is it possible to make something like that it(program) will kill all files after passing 30 days
