Unique ID for all front panel object

[PincoG]

Hi guys,

I need now to the backward path:

from the UID to a control refnum.

How do I obtain it?

thanks

Hi Pinco,

you seem to have a faible for reviving (very) old threads: please stick with your thread and avoid double posts...

Build a LUT (look-up table) containing all UIDs and their refnums.

Then you can look for your UID in question to get the corresponding refnum!

(In former LabVIEW versions we used Variant attributes, now you should use Maps instead...)

The following VI can give you a GObject reference from a UID:

[LabVIEW 20xx]\vi.lib\VIServer\UID to GObject Reference.vi

Hi everybody,

but changing Caption Tipstrip and Description, cheange them in a way the UI is redrawn?

In other words, can I use this method to change the aspect of my UI in running mode?

You don't need scripting for that, it's all plain VI server stuff.

However, you can't dynamically create a caption. If the caption has never been created during edit time, the caption is not a reference, and you can't get one with VI server or scripting.

One would usually make labels unique and hidden and show the captions on the UI. Yu can than use the unique labels to lookup the desired caption and\or description:

You can use UIDs for this, but it isn't as convenient as labels:

EDIT: The tip strip it there too:

[PincoG]

Yes,

i have done exactly as the second diagram you posted, but I cannot see any change in my UD. Why?

If I change the caption from a properti node of that control it works: tha caption changes immediatly on UI.

This function only works in the development environment, not with the runtime.

Sorry,

was my error, the reference map was empty.

It's work perfectly.

Thanks to everybody

Correct. If you need code that works in a built EXE, you'll need to create a map of UIDs. Which is pretty easy to do.

How can I obtain a reference from a number, to change some properties, caption, programmatically?

Thanks again

There is no ready made function for that. Enumerate all controls and search the UID in the list.
