Discover all Classes and llbs being called by a vi

[m3rl3n]

I have a VI that was created by a developer no longer with our company that I'm trying to re-engineer (One version of his SW works, but what's in version control, and complete - doesn't). It is a VI that is part of a larger program and it's contained in the higher level program's project. This lower level VI is a major component of the higher level program and it contains a number of sub VIs that are component VIs of various classes and llbs.  

I'm trying to discover a means through (scripting?) where I can open a reference to the subject VI, and then pull out the names of the classes and llbs that are being used, because their subject VIs are sprinkled throughout.

Any hints?

If your VI used by only one project, you can find all callers from context menu

If you have many projects, you can use script. Here is a draft

That won't find subVIs inside structures.
