Hi All - I am about to start a new project where the customer needs a high level of control regarding what users see and can edit. For instance - I may have 30 textboxes (or other controls) on a form and for any one user I may need to...

a) not display the data in one or more controls
b) display data but prevent the user from editing it

This will vary from user to user...

Any advice on how to code this sort of thing? What techniques to use?

It will be a visual foxpro 6 sp5 application.
