You can add the MAC address of the PC into the source code of VDS before compiling. When the user starts the program, you can then find out the MAC address of the machine to compare it with the stored MAC address... Smile

I believe one of Dr. Dread's DLLs had a function to get the MAC address... Smile

Btw. The MAC address is unique to a machine's NIC (network card), so unless the user replaces his/her NIC, the program should still work.. Smile

There are many thing you can do. You can use @binfile() to append some
data to the end of your compiled .exe and then use @binfile() to load that
info from your compiled .exe to validate it when your app is ran by an
end-user.

one simple thing i do is:

- the user sends me an email with his/her hard disk number, this is easily done with vds

- i then send an encrypted string based on the hard disk number to the user who then enters it into the program which stores it in the registry, and

- every time the user runs the program, it checks that the hard disk number matches the encrypted string stored in the registry...if the 2 match, the program runs, if they don't, then a message is displayed and the program shuts down
