How to determine if the current object is the Active Inspector?

Hello,

I've posted this question just last week, but it is no longer listed here at
all. Can someone please tell me how I can determine in vbscript if the item
is currently the active inspector.

I have a lot of code in behind my form, but I do not want it to execute
unless the item is opened and being worked with by the user. I need to stop
this code from executing if my vba code is accessing the items for some
reason.

What I'm looking for is something like:

If (item is activeinspector) then

Code to execute

End If

Can someone tell me what the proper terminology would be for (item is
activeinspector)? In this case item would be a contact item.

Thanks,

John
