Exit program from inner loop

[Dennis Francek]

Hi im all new to Labview so this might seem like an easy problem to solve.

Im simulating a signal and displaying it on a graph when i click a start button. But i can't figure out how to still being able to exit the whole program from an exit button as long as im in the inner loop that simulates the signal. When i click the Exit button when simulating nothing happens until i press the button to exit the inner loop.

Heres a small example vi demonstrating my problem:

Hi Dennis,

while using an event structure is ok you should consider to never do any long-lasting tasks inside the event case as this will block other cases - and even UI handling if not set properly.

Solution will be to separate event structure/UI handling and DAQ parts...

 SImply follow a few simple rules:

• Don't put interactive while loops inside events
• Don't put events inside events.

You can use the outer while loop for everything.
