Is it possible to get a list of refnums to all VIs loaded into memory?

[BVSmith]

For various reasons, it would be nice to get the refnums of all the VIs loaded into memory (e.g. to abort a VI).
Is this possible?

Drop a property node on your diagram, and select Application/all vis in memory. From there you can get the refnum of each loaded vi. See the attached vi.

Excellent!

Is it possible to get a list of refnums to all ActiveX objects loaded into memory?

I specifically want to be able to programmtically save and close an open excel workbook that has not yet been saved and I don't know the name of.  From Labview.

I know how to manipulate workbooks that I open from a saved location, but don't know how to take whichever workbook is open on my computer and save it to a known location.

Thanks!
