I have a complex workbook including VBA code to be distributed to franchise
outlets however I do not want the workbook copied. I understand that 'dongle'
stle security devices such as Alladin's HASP can only protect .exe files. Is
there an easy way to adapt the workbook so that it can be protected by these.

Alternatively, is it possible to code into an AutoOpen sub a check reference
the IP address of the computer in use and so only have it work on that PC? I
appreciate that this is not a secure solution but may well serve to deter the
casual plagiarists.

Or does anyone know of another method of providing at least a reasonable
defence from having the file copied.

Any help would be appreciated.
