Hi,

I want to prefent users of my programs from using it after a periode of time and also after using my application after 30 times use. It has to be simple but not to simple. So for example the periode/time counter may not be distirbed by changing the system clock. I don't know is some one has asked this before, but it's to much work going through about 2700 questions.
