Open Project VI Reference : How to Obtain a VI Reference without Specifying a Path

[Eric.M]

Overview
This example VI shows you a method to get a VI reference which is contained in the same project as you calling this example VI.

Description
This example VI shows you a method to get a VI reference which is contained in the same project as you calling this example VI. The principle of the VI is to parse the parent project of the calling VI, searching for the VI you specified. If not found, the VI reference is “Not a Refnum Constant”. Otherwise, the VI returns the matching VI reference. The VI Name input is not case sensitive.

It can be very handy when it comes to RT project, where the VI server can be used to run several RT VIs, but where the path issue can be disturbing.

Requirements

• LabVIEW 2012 (or compatible)

Steps to Implement or Execute Code

1. Unzip the attached folder to your computer
2. Open the VI "Open Project VI Reference 2012 NIVerified.vi"
3. Run the program
