Hi

I have a large, complex app, and I want to start breaking the code up a bit into a more 3-tier style.

One of my first objectives it to extract any data-handling from the GUI into custom objects, the only thing that is getting me is where to plonk these data-objects.

For example, most of the forms have buttons down the left hand-side that each call up a different container that contains the screen fields.

Each container may relate to a different data-object, so where should I house these data-objects? and what would be the best way to ensure that the form is accessing the right object for the container that is currently displayed?

Thanks
Kev
