The Dynamic VI Handler is a software add-on for LabVIEW that you can use to test separately-running independent VIs. The add-on provides VI handling functions that help you execute commands such as close, hide, run, show, and more. You can also perform functions for transferring data between VIs without wiring, saving and recalling VIs, loading and releasing VIs on demand, and linking independent VIs through references. Additionally, the Dynamic VI Handler includes examples that teach you how to control the front panel of a target VI, how to share control between several VIs, how to acquire arbitrary control data from a target VI, how to transfer data between VIs, and more.
