In this example, we show how you can refactor existing code. We have taken the 3 button dialog that ships with the base version of LabVIEW and upgraded it to use the JKI State Machine template. We have not added or changed any functionality. Also, we have not changed the way the functionality is implemented.
Here is a screenshot showing how the VI looked before the refactoring:
Here is a screenshot showing how the VI looked after applying the JKI State Machine template:
We've attached the the refactored VI that has been written in LabVIEW 8.2. Remember that you need to have the JKI State Machine package installed in your version of LabVIEW. Click here for information on how to install the JKI State Machine.
The original VI is located at: \Utility\error.llb\Three Button Dialog CORE.vi
