How can we have our own program with a so-called 30 days trial ? and if we have other program with that.. like what we download from internet... how can they tell when the software was started, i think they should write the date some where in my computer. Is there a way to find out?
use registry and use your own algorithm for encrypt this value. i suggest to relate this value with computerr name etc.

i suggest also use a registration via internet where newly installed program gets a timestamp, thats works for sure
