How do you use the "run when open" function?

[Akatsuki]

I have finished my VI. I would like to the VI to run as soon as I open by simply cliking a "start button" instead of the arrow on the toolbar.  Then, when the program stop, I want it to go back to where I started (wait until I pushe the start button again). 

How could I do that?  Should I use a while AND a case statement? Any Ideas?

Thank you for your time,

Noel

No code required. Just go to "VI properties...execution" and select "run when opened".

You cannot create a start button on the front panel, because the VI would need to be running to read its state. Catch 22! Correct would be a big while loop and an idle state for pausing. The VI should always be runing, even if it is not doing much. 😉

How about I create a while loop and inside I include a case structure and one of the case would be while keeps running until I push the "stop button" which I could rename "start button". hope it will work

Nope.. it didnt work.  When it's running, my VI is too slow and I can't even push the button =(

Here is a simple example using events. It should give you some ideas.
