Yes, I have used a dongle putted in the parallel port,
but it need run only on one computer that has been licensed to,
so i want get the one-to-one unique identifiers for computer,
then combine it with some code in dongle.

BTW Remy, could you tell me how to get the Ethernet card
MAC addressed, CPU ID numbers and HardDrive Serial Numbers,
Thanks in advance!

Sky!
