Two while or for loop in app designer.

Hi

I am looking for a way for cancle running loop when a button cliked.

For a example there is a code below.

When I clicked the button1 then cliked the button2, something works2 is on going.

But something works2 is returned, the something works1 is on going.

When button 1 is clicked and button 2 is clicked, I want something works1 to stop and something works2 to start.

How can I do this?

function button1Clicked(app, event)
    while(1)
        %something works1
        if ?
            return;
        end
    end
end

function button2Clicked(app, event)
    while(1)
        %something works2
        if ?
            return;
        end
    end
end

You'll need a global status variable for each process that notes if it is/isn't running. Check its status on the button callbacks and take the appropriate action.

@Jae-Hee Park - or consider using a a timer to perform the repeated actions (instead of a loop) then just stop the timer when the appropriate button is pushed.
