Fire an Event in subVI using VI Server using LabVIEW

[Hesloppy]

Overview

This example shows how to fire an event in a subVI using VI Server.

Description

This example shows how to fire an event in a subVI using Vi Server. The main Vi dinamically launches the subVI using VI Server. It then toggles the boolean in the subVI using VI Server as well. To trigger the event i get a reference to the front panel of the subVI. I then get an array of the controls on the front panel. The index for the toggle button in the ssubVI is 1 so I index into the array of controls. I then write the boolean value to the value (signaling) property node of the control in the subVI. Non that for the example works correctly both VIs must be in the same folder.
