>I am trying to develope a class that enables all/some data fields on the form depending on user access level. Is there a way to enable all data fields (txtfieldname,chkfldname...) in one command or do I need to do this on each form?

Take a look at the SETALL command. This will allow to to set a property (like enabled or readonly) for all controls of one type on a form. Very powerful.
