Demos.Purchasing.Making Registration Code work only once

Well im posting this here because im attempting it in vb. it may belong in the systems development section.

Any way... every body nowadays uses demos.
Well i have created code (in vb) to create a demo with a time trial, and the user can enter a purchased registration code,

My question is, how can i make the program so a registration will only work on one trial and not on all the others, (ie...unable to pirate copy)
I assume it must require using the net to do this,
I predict a solution might be that a array of codes already used, and an array of new codes available, is downloaded from a server and then checked, accordingly.

My problem is, is this the right way of tackeling the problem
2nd problem is implementing it.

If any one wishes to see the code. i created for a simple demo with trial period... i will be posting it in the howto section in a couple of days
