Hey! So, if you are wondering how to do callbacks in LabVIEW, LabVIEW help and shipping examples are a good place to start. If you open LabVIEW and go to Help >> Find Examples, this will open NI Example Finder. Then go to the search tab and search for "callback". This will bring up to good examples on the general procedure. If you are asking if this specific function will work and you know how to impliment it, I would say try it. I personally have not tried it or found anyone that has. If you have any errors as you implement it, let us know!
Hope this helps!
