Sorry,  I've been coding listboxes a lot lately and misread what you

had typed.  I

don't have an answer for you other than I doubt there is an easy way.

Actually, I was referring to a "combo box" not a listbox.  Maybe I

am using the wrong name.  This is the type of object that can be

typed into as well as having a drop down menu of sorts that can be

used to select the text that will eventually end up in the typing

area.  It looks like a regular variable or field with a button on

the right end of the object.

I do examine the form's objects and as I run through the array of

pointers, I can determine the type of object of most, but when it

comes to these, I could easily mistake a normal "pop-up/drop down

list" for a "combo box" since both will return text array using the

Type call (if each object represented a text array).

I was trying to avoid hard coding for each of these objects on every

form.  I do that now, and it is just another step I would like to

avoid every time I create a form that incorporates one of these.  I

was hoping that there was a command that I was not using that

returned a unique ID that represented all of the available form

object types.

Eric,

If you are using 2004 and newer, you can use GET FORM OBJECTS to get a

list of object names and corresponding variable Pointers.

So if you use a naming convention for Combo boxes, you can simply

determine if the object is a Combo Box by looking up its object name.

Another method could also be to embed this information in the array

name itself.   Sadly 4D has denied us the ability to determine just

what form objects we're dealing with using a simple command   >  20

years and counting!

There might be plugins out there that can do this, I am however not

familiar with them.
