Perhaps you could use a property of the object, rather than the object
itself. I had to find a way to detect if my object had suddenly become
Nothing - that is, the user closed the file without using the Exit button
that would also close the VB app. Not being very experienced at this, I
probably went the long and tedious way around, but I set a Timer function to
set the name of the object to a string. If it errored, the file was
closed - I detected the error and shut down the VB app.
