Hi,
I would like to give someone my software for testing and I don't want them to run away with it, so I'd like to protect it somehow. I'd like the program to become inactive after it has been run (used) for 5 times. I already know how to make the program to self-destruct, but I don't know how to make it count how many times it has been started. Does Qt have support for this kind of counting? This is usually done through cookies, I think, but cookies can be deleted. Is it possible to make the program itself count how many times it has been used? The other way to do it would be to check the date and delete the program on a certain day, but again, computer clock can be changed.
I'm thankful for any ideas you might have for protecting a software. What is the best method?
Thanks!
