Update and change values when VI is running

[studentgirl]

Hello everyone !! I have a slider numeric control and I want to be able to change and update the value when Vi is running. Can I use property node for this?

[RavensFan]

Sure.  Or a local variable.

These questions can be answered by taking those tutorials.

I was not able to find one which uses property node. Sorry about that.

If it's a CONTROL (not INDICATOR), then it's intended for the user to set the value via mouse / keyboard.

You can still set the value via PROPERTY NODE or LOCAL VARIABLE, for ANY control.

What difficulty are you seeing?

Hi,

Heres an example for you.

-create a while loop
- connect stop terminal to Boolean button.
- create numeric control inside Loop.
- create numeric indicator and connect to numeric control.
- keep some delay inside Loop.
- now run vi and Change value in numeric control and see whether numeric indicator value changes or not.

Sorry the problem is not solved yet. The horizontal slider control lets the user to choose the number of samples to display on the graph. The problem is when I run the VI and I change the value of samples through the slider, it does not update the values on the graph.

Please post code and if you have another question it is good habit to start another thread .

You have shown NO code, so can you explain how anybody could possibly help?

 The problem is that the code is confidential so I can't post it. But the only problem is that it is not updating the values in the graph.
