is there any way of getting the label of any variable as a string ?

[zmuccelmic]

After I label any indicator (or whatever) is there a function that reads that label and outputs a string ?

[altenbach]

You can read the "label.text" property.

Ok but in order to use this i need to link the property node to that variable. What I was thinking is something like a SubVI or a structure that for whatever variable (labeled) as input it outputs the label as string. (something that will autolink my property node to the input).

You could use Altenbach's code as a VI and wire in a reference to the property node.  Does that make sense or do you need more help?

I think i need more help.

I created a suvbi that looks like Altenbach's code, i connected a terminal to the indicator, but whenever I use that subvi and input a variable, the label does not pass to the indicator in the subvi so as an output i get the label of the indicator inside the vi.

Also I'm not sure what that reference should be. Can a reference be a let's say integer type indicator (control) ?

Code and image attached (I'm using 8.2)

First of all, the reference is a control -- it's connected to the connector pane.

This will only work for numerics.  I figured out a way to get it to work for generic references, but I didn't do it yet and it's probably too much work unless you really need it.  There might be an easier way...

When you this subVI from another VI, you would connect a reference to the object whose label you want to the input terminal.

Let me know how it goes...

[MattBradley]

If you need one for strings, it's not that hard.  Minor changes to the code.

It seems to do the job. I have no idea what those control refnum are but hopefuly I'll figure out eventually (I just started using LabView 3 days ago 😞 ).

 Thank you !

It works if for a certain variable i create a reference first and input that reference to that subvi. Is there any way that i can just input the variable ? (I do have a lot of them and I dont want to create references for every one of them.)
