I remember this thread some time ago with Mr Moore. I took that and typically do map my .ControlSources to object properties. For simple data maintainance forms, there is one class definition and one data maintenance form. These two classes are handling some 30 different data entry forms. For more sophisticated forms that require lots of biz rules, they have their properties explicitly defined. I use INSERT/UPDATE/DELETE SQL commands that get their values from the properties of the object. I find that this is working well. Each of these biz objects could be created as automation servers along the lines of Gary DeWitt's - Build Active X Automation Servers in the August 1997 Advisor.
