Crazy while loop?

you! My problem is that only. How do you stop the outer most loop?

Change the architecture.  Try what I suggested and you'll see, it's faster to do and easier to understand and debug.  Forget about what you attempted, it's just going to cause you headaches..  😉

Of course it will work.  The stop button then becomes a Stop Program button.  You can do one, two, three operatins, repeat them, etc until you press the stop (program) button.  You'd have 1 stop button and as many operations button as you need (three in this case).  And 1 single loop that is easily controlled.

The Event Structure is quite easy to implement.  And much cleaner solution.

Yeah, but in my case. There will be totally there will be 3 start, 3 stop and 1 program stop button. Then....yeah maybe I will try that.

I forgot to ask which version of LV are you using?  Because Event Structures are not part of the basic package 😞

Also, I am curious,  why do you need 3 start & 3 stop buttons?  Does it not stop automatically after doing what it has to do?  Can you elaborate?

Hi Halemani,

if you press the stop4 button, you have to start and stop the other loops again, then it works for me.

Here is an event structure example.

Hope it helps.

Ok, I have three charts I am sending my data. Then I will choose which chart to start showing data. Then I will choose to stop or start the other charts. Hence, 6 buttons for three charts(2 for each, start and stop). Then after I get bored I choose to stop the program.
How is it?
Also, i have event case(LV8.0).

Wow! Mike. Wait let me catch my breath! Why don't I think like you friend?
Thanks it did work. Although I need some time to understand the code.
Thanks Mike babu and Ray babu(in India it means friend)

Glad you like it and thanks Mike for providing a vi.  No labview installed on my PC 😞

Try to adopt that structure... It will help you code more efficiently in the future. 😉

Back to the original code

"Stop 4" is probably being read before the other loops run. If you put the "stop 4" button in a seq frame that is only executed afte the other three loops terminate, the button will be read AFTER the inner loops terminate.

No, Ben it won't work.

Hi Halemani,

your are wrong in this point and Ben is right.
If you press the "stop4" button before you stop the last loop, it will work.
See the attached example. However, I prefere the event structure method.
