Restricted Program Access

[Steve_F]

I am making a program that people will, hopefully, buy. I want it so that everyone can't use it. I was thinking the best way to go about this is to get their HDD number and if its valid they can use it. This way when they pay I can add the number inside the program and when it loads it auto checks for an update. This prevents people with usernames/passwords from sharing. Is this the best way to do it?

I think this is excatly what you are looking for: A Program Registration Scheme

This prevents people with usernames/passwords from sharing. Is this the best way to do it?

Well by this way i know few people that will publish a key generator for your app in few minuts
