Rodd:

I am strongly in favor of Subclassing no more than one thing (Form, Textbox, Combo, PageFrame) at a time, but I'll admit it's a Developer bias; it makes it so much easier to mix/match, reuse, delay instantiate, etc., etc...I have dealt with WIN95 workstation speed issues also, but slowly they've been replaced with more modern boxes and the problems have diminished.

Perhaps you could look at multiple separate Forms with their own Init events instead of a Pageframe? Or actually drop the items on the Page only at the moment it is Activated? That way, if they never visit Page 2 it will never be populated with Controls...tricky but interesting...

Just some thoughts,

-Irv.

The real division comes in trying to decide, do we paint all the fields on our form class using the class designer or do we store information about positioning in a table and programatically place things on the screen when they're needed. In other words, if we have a form with 2 pages (in a page frame) -- 1 page for a grid view and the other for a data entry view -- and the user only comes in to look at the grid view, we would never have to instantiate the objects on the second page.

Not being able to lay things out visually is a real pain and yet doing so can slow the instantiation of a form down considerably ... especially when you're still supporting some slow Win95 machines.
