Hi manhongw,
Welcome to the Forum.
The short answer is, no, there is no way to stop FormOrg copying your codes.
There are two ways to prevent copying:
The first is bullet-proof ==> don't give your codes to anyone. This is the only real solution to prevent unauthorised distribution.
The second is to write the functionality in a dll and use copy-protection to lock the dll. This isn't foolproof and can by bypassed by dedicated hackers, it's not "easy" but it's not that hard either!
Hope this helps.
