Issue Details

I am programming a top level interface to command the hardware of another company. They are proposing Message IDs formatted like "fbdc0d3e-25c8-41e0-ab90-d028123c9f18". How can I create these in LabVIEW?


The Message ID asked about is a "universally unique identifier" (UUID), also called "globally unique identifier" (GUID).

They can be created in LabVIEW using .NET's Guid functions:

Additional Information

Another way to create them is using one of the VIs made for this purpose that are pre-shipped several of National Instruments' software packages.

One is which comes with NI-DAQmx and is typically located here: C:\Program Files (x86)\National Instruments\LabVIEW 2017\resource\Framework\Providers\API\ This example path refers to an installation of LabVIEW 2017 32bit, change it accordingly to your installation of LabVIEW.
