Problem deleting an indicator ....

[marc france]

Hi everyone,

I have a numeric indicator on my diagram page that isn't wired to anything. When I double click on it, I don't see anything on the front panal. I would like to delete it but it doesn't work : I have tried  the delete button and  the delete Edition one... but no success

Would anybody have a clue....?

Lab 8.0, XP

Thanks a lot,

regards,

Marc

Hi Marc,

just my guess:
have you tried right-click on terminal and 'Show indicator'? After this the indicator should show up on the frontpanel and can be deleted.
Other possibility: delete the indicator by deleting the terminal (you have to allow this in the LabView general options)

But:
even a hidden indicator should show up on the frontpanel when double-clicking the terminal (normally in 'grayed' style). But you cannot select it...

Are you not able to delete this indicator even on Block diagram page????

Probably the indicator is hidden,  see this link for displaying a hidden indicator and then delete it on front panel

Hidden or not hidden, you should be able to delete an indicator from block diagram too.

If you cannot, attach the vi that is showing this behaviour so that we could see it and suggest better

Hi Marc,

same behaviour with your vi on my pc. Can't delete the indicator and don't know why.

Nevertheless, if you just want to delete it: Change to constant and delete... It worked for me...

Hi Marc,

yes, there is a problem.
Even in LV8.2 I couldn't delete this indicator. I can copy it and edit/delete the copied indicator - but nothing helps on the original one...
Also the label of the terminal is not shown (or hidden somewhere in the block diagram)...

So my advice: To get rid of such problems you can (or have to) recreate the whole vi! Do this and keep my 2nd advice in mind 🙂

2nd advice:
Try to learn more about dataflow and LabView programming.
You do unneccessary things in your vi like copying values from a control to its own local (several times in the while loop in the center of your diagram). Never compare floatingpoint-numbers with 'equal' operation (inside upper sequence, while loop named 'Prochaine acquisition (S)'). Try to use less locals, usually you don't need them.

P.S.: You don't have to answer both of us (Dev and me), when your answer is the same. It's an open forum and we all can read your replies 🙂

Hi STT,

yes, your option also works for me.

But I am curious. LabView likes to remember such 'bad things' and will present you a wierd warning/failure sometime in the future. So I still would recreate such a vi from scratch!

That's curious. The indicator terminal label has been boosted very far upward from the terminal itself. Also, when you try to show the indicator by clicking on the terminal, LV points to a fornt panel region very far (downward) from  the other controls. Probably, some internal limit has been exceeded and LV can no more manage it.
Anyway, as pointed out before, you can change the indicator to a constant and delete it.

I never did find the label!

I posted this the the bug thread.

I have seen this myself but I could not recreate it!

Do you remeber how you managed to achieve this effect?
