SubVI dialog box

[RavensFan]

Why are you enabling and disabling VISA events, yet never using the VISA wait on events function.

In your main vi's block diagram, right click on the sub-vi select "Sub-VI Node Setup".

Make sure "close afterwards if originally closed" is checked.  Based on the other comments, the termination terminal of the while loop looks like a stop sign in the bottom right corner.  Connect a button to this.  When the button is clicked, the sub-vi will stop.  If you have the node setup-options correct, the window will close on it's own once it stops running.

It's how you stop your loops.

It is annoying for the user.  Do you like to work with programs that have dialog boxes on top of dialog boxes?  I certainly don't.
