Can't Write to Label.Text Property Node

[Brian_Vibert]

Craig,
What you need to do is raise the refnum to a more specific class using the To More Specific Class function. You will need to wire a cluster refnum to the target class input of the function. Then you can use the controls[] property just like you would for a property node on the diagram for that object. See the attached example that should demonstrate what I mean.

Hope this helps,
Brian

yup ...

that's the ticket ...

very cool !

If the reference to the cluster doesn't contain an array of controls[]
references, then its type isn't a reference to a cluster. You might
need to cast it to more specific, and wire up a cluster class constant.
The output wire will go into a property node and let you access the
controls[]. If there is no error at runtime, indicating this is indeed
a cluster, then it should do what you want.

I don't like answering a question with another question, but why are you
wanting to do this? The label is part of your program in addition to being
part of the panel. It affects the name of data that flows to the diagram
and is returned to the caller. If you intend to change the name for the
UI only, then use a caption instead. Popup on the control, choose Visible
Parts>> Caption, and this is purely panel. It can be localized or changed
at runtime.

Use the "caption" in the same way you intended to use the label.

I must have been answering at the same time as Greg. See his answer.

I've encountered exactly the same problem. Thank goodness it's been answered. I'm happy to use Caption rather than Label - this works fine for me. But why isn't this problem documented by Nation Instruments? And why does the property node Label.Text accept an input that (as far as I am aware) is ignored?! Worse than this, it appears occasionally to crash LabView 6i without warning or explanation!
