Hi Larry,

> To do this is it necessary to go into every control and place a call to the security manager to check the user's credentials? (I've got a hundred controls....). Could these be put in at the form level?

You could set the form property: lWriteLock = .T. to enforce readonly on all controls.

Also, you may want to make a provision for controlling which users can create, edit and delete information. Once you add these items to your security privileges you can then utilize the form properties: lAllowDelete, lAllowNew, lAllowEdit.
