I am thinking of writing a small shareware program. It will basically be a program to allow users to edit which program start-up with the computer. However I will try and add a few extra features to make it worthwhile with all the similar programs around.
I will have a shareware version & a full version. The full version can be downloaded once the customer has registered. But with the shareware version how would I either:
a) restrict the trial to 10-days or something- how do I monitor that the clock isn't set back etc.
b)or restrict the number of times the program can be used before it must be registered.
