Parallel testing with SN dialog

[Sam.Huang]

Hi all

  I just have done a parallel testing demo with Labview queue pattern,first time execution is OK and then is stuck,I don't know what's wrong with this code, Please help me for this bug, thanks in advance!!

In my mind purpose is when execution first appear SN dialog and scanning bar code show thread 0 start testing and scanning bar code again start thread 1 start testing,in the period which thread pass then appear SN dialog again scanning bar code continue execution new testing.Anytime push "Stop" button  abort testing in priority and push"Exit" button or close panel immediately close panel.
