Hello all. I have seen this code before on here and searched everything but could not find it. I have the program to send to the user where it will create the key. The key is their hard drive number. They Will send it back to me so I know what it is then add it into my project so at start up it will only load for the people that have hard drive serial numbers of which are listed. If it is not there then it will not load for them. So i am just looking for code or an example or help of it to show me how I can have it load up for only certain hard drive numbers and not for others? Well thanks in advance guys for all the help and it is much appreciated. Have a good one Peace
