Is it possible to retrieve "This VI's SubVIs" programmatically?

[Petru_Tarabuta]

The View >> Browse Relationships >> This VI's SubVIs menu option reveals the names and icons of all subVIs used in a given VI.

Is it possible to retrieve this information programmatically?

Hi Petru,

Yes, but you need to enable VI Scripting:

You might try turning on VI scripting nodes under tools\options\vi server\VI Scripting



It looks like there may be property nodes that return references to subvis found on a VIs block diagram

Property "SubVIs[]" of class "Diagram" only gives SubVIs at the same level as the diagram, it does not get SubVIs in nested subdiagrams recursively.

Thanks both!

You can also use "Get VI Dependencies".  No scripting needed => works in exe.

To find common SubVIs of given multiple VIs, in addition to call the above VI in a FOR loop, we can also create a project programmatically and add all VIs to it.  And then retrieve dependencies from the project.  Save the trouble to remove duplicates.
