Look in the Solutions (provided with VFP), under Windows API "Read and write VFP registry values". It uses the registry.prg (provided with VFP) to access the registry. Mike Gagnon

You could try Armadillo from

http://www.siliconrealms.com

which supports VFP. It is both a licensing and copy protection software.

It has a hardware locking feature allows you to "lock" a registration code to a specific machine. The code will only work on that machine, or an exact duplicate of it.

And an evaluation copy can be downloaded from the site.

I have no idea how it's done, but a 3rd party piece of software we use somehow uses the serial number of the hard disk as part of its key.

Only discovered this the other day when my hard disk died and I had to reinstall the software. The original password no longer enabled the application, and I had to go through a process of re-registering with the new info! "I love work. I can sit and stare at it for hours..."

Microsoft has published some API stuff that can be used within Visual FoxPro to get the hard disk serial number which you technically can use to "validate" that the hard drive on that PC is allowed to run the app. If that app then were copied to another PC, it wouldn't run because the hard drive serial number would be invalid in your app.
