Extracting element labels from a cluster

[GDthomas]

I need to programmatically get the labels from the elements in a cluster. I've figured out how to get them one at a time using property nodes (see below) but since there are quite a few elements in the cluster this would get rather bulky not to mention tedious. Does anyone know of a better way to do this?

Thanks

Hi rtpumps,

using a property node of the cluster you get the "Elements[]" reference array.

Then read the "Label.Text" property for each element:

Hi GerdW,

We must have different versions of LV because there is no Elements[] in the property node but one called Controls[] that does the same thing. It's just what I needed.  Thanks!

Gerd is German, so his properties probably have different names.  You can see that one property is "Beshcr" .text

A better solution is Get Cluster Information and Get Type Information from the Programming -> Cluster, Class & Variant -> Variant -> Data Type Parsing palette, as shown below. Before LabVIEW 2015 or so, similar functions were available in vi.lib\Utility\VariantDataType, but those are now deprecated in favor of the newer versions on the palette. One major advantage of this approach is that it works in executables on RT targets, whereas the property node approach will not.

Hi,

yes, I'm using (or: have to use) a German LabVIEW version.

"Beschr" is the abbrevation of "Beschriftung", the German translation of "label". "Caption" would be "Untertitel"…
