The same thing can be done for any application including C and C++ applications. That's why obscufator programs exist. I'm sure the temptation for customers to make changes is worse with a script application like ASP or PHP, but either way it should be a violation of the application licensing terms.

Thanks your reply! Yes, with script application, you can't hide anything on your source code; and i can't find anyway can help about it. With windows application, you can package it to be dll files. Thanks again!

Yes, but dll files can be decompiled and you can find the value and modify it in the binary. I used to do it to change the colors displayed in a simple enhanced directory list conosle application all the time. The only thing that really prevents customers from making the changes is your license agreement with them. If you are really concerned about it then bury some code in the applicatin that uploads the setting to your servers periodically and then verify it with what they purchased. It is probably better to make it easy to add licenses then chase after people that cheat on the upgrade. At least you got some money out of them.
