Hi Nandhisha,

There are different ways to do this. I am explaining two of them here,

1. Pass reference of boolean button which controls main vi's while loop in to the sub vi. When sub vi got stopped write a true value to the value property of the refnum that is being passed in. This will stop the main vi while the sub vi is being stopped.

2. Define a boolean global variable which can be written in the sub vi and can be read from main vi. So here also the main vi will be stopped when the sub vi is being stopped.

You can choose any one which is convenient for you.

If it is the case and if my understanding is correct the scenario can be explained below,

The calling vi will automatically get stopped and come out of labview memory if it is not having while loop in it. And use the exit labview function in the sub vi to quit labview or otherwise pressing stop button itself will stop the sub vi..
