Overview
This example shows you how to update a calling VI's front panel from within the subVI without using references to the controls, indicators, or the VI.


Description
In LabVIEW you are able to use the call chain of a single VI to find the name and path of calling VIs. That information can be used to programmatically call controls and indicators without the explicit use of a reference to the top-level VI.


Requirements

  • LabVIEW 2012 (or compatible)


Steps to Implement or Execute Code

  1. Download the attached files to your computer
  2. Open the VI "Update VI's Front Panel from subVI LV2012 NI Verified.vi"
  3. Run the program
  4. Observe the graph being updated from the subVI
  5. Click STOP to stop the VI
