Ricardo,
I always had trouble with n-tier terminology:) MVC or facade-data-logic are most popular application models but ask me, I can't even define what they really are. MVC pattern when I read it sounds to be the thing that I do everyday but I really can't say it is. Currently studying distributed architecture and doing what I want (not with VFP) but I still can't say what is MVC:)
Anyway if you don't mind about my limited understanding about it I'll try:)

View: Is display part (UI) - forms,reports.
Controller: As I understood it's event handler. Like handling a mouse click.
Model: Data (with behaviors of validation,retrieval,save etc)

Though VFP is an OOP data operations are procedural in nature (not just VFP). However maybe it is so because for a developer it is easier to manage data traditionally rather than OOP. Not only that of course, speed (VFP community puts speed in 1st place I think:) sounds to be another factor and we easily give away overheads needed for loading/saving through objects. Yet another factor almost any developer tends to code directly in UI (at least I don't deny I do, just I find it easy for a job when time is tight on design). Binding to data directly is yet another face of it. Come to think of it, I can bind a grid to a cursor/table but not something like an object,array etc that is an IList (ok this is VFP:).
Examples, unfortunately I don't have an example short enough to post here (not only being short enough but needs to be stripped from propriaty code first). COM classes would be a sample but I don't like COM classes and keep away from them.
Sorry couldn't help.

>>Are those "children" running within the same app? If so:
>>Keep the value you read in a property of custom oApp object. In init of your class it checks oApp.savedvalue. If it exists use it else do the select and populate. Or your class init code could do the select in init if it's not something time consuming (ie: over network, after intensive calculations etc).
