Uhm... No. Your answer had nothing to do with the body of my post as my question was super clear: how can I grab text highlighted in yellow? Your answer had nothing to do with grabbing the text highlighted in yellow. If you dont know the answer thats fine (me neither, thats why I've asked), but then you should not respond.

Are you okay?  Do you need a hug?

Sadly this information is processed by the gui just to be readable and can not be accessed programatically imho.

As you said by yourself, getting the information it is a cluster, it needs to be extracted and processed again.

I added a vi for you, I hope that helps to get the basic idea.

Sorry, there is no way to programmatically access the string in the variant indicator; except for the following:

1. You can get an image of the indicator.
2. You can instruct the user to click on the text, then get a reference to the object with key focus (which will be the text object you want).

Theoretically, this should work (but it doesn't):

Of course it's still possible that if you put the right magic values in the array, you might get what you want.

If you want to get kludgy, try this.

Also we can invoke the "save terminal image" (something like that) method and then do OCR with vision builder. I guess t.n.14 nailed the solution, just need a bit of a recursion.

I was deliberating with myself for a while if I should post this. But here it is. It's literally the exact thing that was asked for initially.

Warning:

This is calling an officially undocumented LabVIEW function. It should be present since around LabVIEW 8.20 or so. As an undocumented function NI has the right to change or remove this function at any point in the future and it may therefore crash, sing a lullaby or or eat your hard drive if you are unlucky. Test very well before you decide to use this in anything but experimental code!

Hi rolfk, it does not work for me with LV2020:

That's what you get for quickly posting without in depth tests. This one works on my system. I had been using this function in some experimental C code a while back and quickly transferred it to a VI.
