Programmatically Set a Property Item

[paul_cardinale 11]

I want to set a property item in a Property node.  For properties that have a single ID, I can get this method to work:

For example, setting a property item for a Control property node to "Label" simply requires the ID string "6332005"; yielding:

However many properties require more that one ID.  For instance: requires "6332005" (Label), and "632d800" (text).

I can't find a way to set a property item to a property that has such multiple levels.

Does anyone know how to do this?

Someone from NI can chime in, but I think this is not possible and is one of those limitations of LabVIEW Scripting.  QuickDrop has a CTRL+Shift+B that operates on a property node and it has a limitation of not working with "dotted properties".  I assume that's due to a limitation with LabVIEW's scripting otherwise NI would have supported it.

Correct. Scripting does not support setting dotted properties.

I found it!  Unfortunately it's deprecated.

It takes dotted inputs as either names or ID codes.

Wow I never knew about that and the fact that it can handle dotted properties is awesome.  Darren is there a reason we shouldn't be using this thing that does exactly what we might want when the proper method lacks this functionality?

[Darren 172]

I had no idea this existed. I will look into it.

Thanks for digging this up, Paul. I got it to work for dotted properties of multiple levels (so not only Label.Text, but also things like Terminal.Wire.Terms[]). I'm going to try to update the VI Server Rename plugin for Quick Drop to allow setting dotted properties by using this deprecated property. (?)

So does that mean that this deprecated function is still semi-supported?  I assume it was deprecated for a reason, is it unstable under any known circumstance?
