>I have some applications written in vfp7 on the market. So far, I didn't implement any protection in it against copy.
>I wonder about the best way to protect it ? Using disk serial number and/or cpu serial number seems to generate a number that I can use to provide a key number seems good but I see a problem when the application is installed on a multi-user site. I don't want to provide a number for each individual pc. I would rather provide the number once. Is it possible to get a number from the server? Or maybe use the server IP number ? Or something else...

Here , what we used for FORTRAN programs and I think, it will go for VFP also.
We took few flopies, made holes by laser, measured map of the bad blocks.
And this flopy was queried each third day of using software ,eexta to password.
