either pass only the data required or the controls containing the

don't see why you'de have to cycle every control on the window.
If you don't
know the number of the controls/data you need to pass, make the
parameter an
array.
Actually, I think it's better to have a reusable module that takes
ANY window and extracts data from the various elements where data
is stored within than to build the same sort of functionality into
every window of every application.
Yeah...the machines have to do more work, but that beats the heck
out of ME doing more work in writing code.
The question remains, how do I access a control element, such as
an EditField with a Control Class object?
You cast the reference to the correct type.
For i as Integer = 0 to self.ControlCount - 1
If Control(i) IsA EditField then
...
ElseIf Control(i) IsA PopupMenu then
...
ElseIf ...
Else
End if
Next
But I don't see a good way to make your approach work in general.
For example, suppose you have a PopupMenu. How does one know
whether its values represent tables or fields? You can begin
writing subclasses of controls like SQLTablePopupMenu...
I've got a module method that extracts the data from things like
Popup Menus. I'll be passing such a control to that module to get a
return value for the value contained therein.
My current challenge is trying to get the data from a simple
EditField. I'll tackle the others as I get to them. And, where you
put the ellipsis is where I'm not figuring it out.

Chuck
