LabVIEW won't let me update name (label).

Solved!

I have on the front panel this below

If I change it to C1 as shown below, save it. Then when I reopen it, It still shows Label. What is going on? (See attached VI)

Are you sure you're not updating the text?  Your label isn't visible.

Why do you expect LabVIEW to save the actual value of a control within the VI without explicitly setting that value as default???

 

Best regards,

looks like a string control with different values. The control label is not shown.

If you change the value and want it to be the new default, you need to set it as default before saving

 

Select control...menu...edit...make selected value default

or

right-click...data operations...make current value default

It would be really, really bad if Vis would save all current control and indicator data.

Thank you, Mr. Altenbach! My problem is solved. I just did what you showed on the picture.  Also, thanks to everyone.

If you think about it, it would be really bad if every time you save a VI it would save with all the data in all controls and indicators. That could amount to gigabytes of data, making the VI potentially gigantic. It might even contain proprietary data that the next user is not supposed to see.

 

Typically, controls (not indicators!) of most subVIs should have defined controls values (typical values, sentinel values to detect if terminal is connected, etc.), so please vote for this idea. Except for very rare cases, indicators should not have defined default values.

So you problem was you were trying to update a label but were actually updating the text and somehow saving the text as a default value was the solution?

I completely agree. This is an idea that NI should definitely take into consideration.

I was trying to update the text. So I was failing to make my update (text) as default value.

Sorry, I am lost, what was the idea again?

 

Because, you have been able to edit Label for as long as I can remember.
