Hi James,

Couple things:

AddProperty to _SCREEN should not be done in the form, because you can only add a property once. If you have multiple top level forms the second one to execute the AddProperty will get an error. Your main prg should perform the AddProperty at the beginning and set it to .NULL.

If you are basing your forms on a single "base" class, you could put code in the Activate event of the form:

IF this.ShowWindow = 2
   _SCREEN.TopForm = this
ENDIF

and in the Destroy (and possibly in the Deactivate):

IF this.ShowWindow = 2
   _SCREEN.TopForm = .NULL. && Prevents dangling reference
ENDIF

This code would prevent the need to keep a stack. The Application.Forms collection is just as good as a stack.

It also looks like you have your own global application object oApp. Rather than adding it to _SCREEN, why not add the property (using the Class Designer, rather than the AddProperty method) to your application object?

SET OPINION ON < g >
The AddProperty method is a work around approach to mistakes in design in my opinion. Except for special circumstances (such as adding something to _SCREEN for example), I always add the property to the proper class in the designer.
SET OPINION OFF

Hope this helps

I'm playing around with dynamically resizing (the file examples and the Jan 99 issue of FoxproAdvisor were very helpful, thanks). I'm trying to find the right command for determining the name of the top level form, from within the application. I tried using _SCREEN, _VFP, and APPLICATION, but no joy. So far, I'm able to get it by using the following code:
