Hi
I'd like to write a "licensing component" for my windows application which I'm developing in visual studio 2005 and C#. It should be able to activate the trialware to a licensed one.
It should use CPU-ID or any other thing about the hardware of the user's computer.
The user should announce the serial number made with my component to me and I'll give a license key to him/her.
I need a sample or the "know how" about it.
