There probably is, but it seems a bit like overkill... I would

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 can iterate over all the controls in a Window (see ControlCount)
You can test what kind of control it is with IsA
Doing that already with the clue passed to me by someone last week.
But, every window may not want to use every control for building a
SQL statement.
True. I've got an indicator in the name of the control as to whether
this control is to be looked into for data.
You might want to create subclasses of the standard controls and
have them implement an interface (say SQLControl) that allows you
to set whether it's used or not instead of having to write code.
And you might have each control return it's value as an
appropriately formated value for a SQL statement (maybe a
"SQLString" method in the interface)
Then you can iterate over all the controls and everyone that IsA
SQLControl you just get the SQLString from it and you ignore all
the other controls
Doing something like that.

Chuck
