>Where exactly do you need to prevent VFP functions from being used? Normally, in your programs, you, the programmer, choose what functions to use. The end-user doesn't get much options in this respect.

Yes they do. There are several areas of my application where I let users write code. I keep that code in Memo fields and it is Compiled and Run on-the-fly.

That way, users (Power Users, System Administrators, in general) can Customize diferent parts of the application.

But there are parts of my application where I want to prevent them from executing some of the VFP Functions.
