change dinamically caption

[Gatet]

Hi, guys!

How can I do to change the name of a nuemric control dinamically? I call the Properties Caption>Text or Label>Text, but I get this error:

"LabVIEW:  In edit mode, LabVIEW cannot return a property for a control part that you have not yet created"

Anybody knows about this issue?

Thanx!

Hi

You can't change the text of the label during runtime, but can change the caption text. If you try to write both values together, you will get an error as you try to write a not writable property.

Ok, I´ve realized about the problem (and understand the error message): before I have to make the caption visible!

No, you don't have to make the caption visible. This is just a kind of additional text you can change whether it is visible or not.

Actually, in 7.1 there is a quirk that forces you to manually make the caption visible before you can use it's properties.

You can read a bit more about in the LAVA buglist forms here.

Ah - that's nice to know. Hope in LV8.0 it is fixed, as I change to this version when we have it in our company.

It wasn't fixed in 8.0 (assuming they even consider it to be a bug).

[becktho]

Thanks tst - you really make me looking forward to LV9.0

[EdDickens]

Yep, not fixed in LV8 because NI said it's not a bug, it's changed behavior between 7.0 and 7.1. So don't expect any future versions to have "fixed" it either.

One important thing to note is that now, if you want to use any property which is related to the caption, you either have to do it in a seperate property node, do it as the last item of your property node or set the property node to ignore the errors, because once the error was triggered, the rest of the code will not execute.
