1. Add big boolean button on your front panel, and lable it "Run";)
2. Hide toolbar
3. Make your VI run when open
4. At the beginning of your VI, add a while loop.
5. Use the big "Run" button to stop the loop, and start run your VI.
6. Don't forget to add an time delay in the while loop, so that it won't take too much cpu time.
