First what version of Labview do you have? I don't really understand your question. As I understand it you want to exicute code when the start button is pressed and different code when the stop button is pressed?

If you could post your code that would also help.

Hi Soundarya,

if you want to run the same code if you press the stop button, then you can use a property node of the start. Use the value(signaling) property to trigger the code from the start button.

Hope it helps.

You could also use an event structure and have both events registered to the same code. That is why I asked what version of LabVIEW you are using so I can help with the easiest solution. I can tell you about ten different ways to code this but it will depend on the version of LabVIEW and what you are ultimately trying to accomplish.

Buttons don't have code (unless you have an xcontrol).

Please clarify what you are trying to do, preferably with an example.

(If the same code should run in the start and the stop case, it simply belongs outside the case structure.)

have you tried an event structure or a state machine

[Soundarya]

I have used value(signalling) property. How should it get connected?

Thanks in Advance

I assume that you have code inside a Case Structure connected to Start button.

If you want to call this code in Stop button also, just make it as a SubVI by selecting the piece of code inside the CS & using the menu option Edit >> Create SubVI... thats it.

But it is highly illogical & totally meaningless to have/call the same code in both the Start & Stop buttons, as their names suggest what is their respective purpose.
