Finding vi running in subpanel from a subpanel control reference?

[Belzar]

I've poked around considerably and cannot find a way to take a control reference to a subpanel control and get the vi reference for the current vi running inside the subpanel.

I know I can save this locally inside the vi containing the subpanel (from the invoke node call to insertvi), but I'm wanting to do this externally from an app that just has references to all the controls.

Any help would be greatly appreciated.

Thanks

Well, you put the name of the VI (or a reference to it) in a hidden control on the calling VI. The it would still be available - just from a different control.

Yeah, sure that works, but I was hoping for a generic answer that imposes no design requirements on the VI in question.  What you propose is a good fall back if there is no way to do it through the api.

Not sure why NI has no easy way to find this out.

If I'm interpreting you correctly, you would like to find the VI reference of the subpanel VI based off one if it's control references that has been passed to some external application from the VI that contains the subpanel VI?  See the attached VIs for an example if this is the case.

"VI with subpanel" passes a control reference to "SubVI" which can then get the reference to the "VI in subpanel".

Close, but not quite. The issue is given a reference to the VI with the subpanel, how do you find the name of the VI that appears in the subpanel.

Ah, I understand now.  A list of subpanel VIs does not appear to be exposed through the owning VI.  I've created a product suggestion for this to be exposed.  You'll need to explicitly pass the reference of the subpanel VI to the external VI/app, or its path/name, or the way I posted earlier.
