How to trigger Labview to run code based on windows user logon or logoff?

[Kyle97330]

I'm not 100% sure that I understand what you're asking but I think that step 1 is to configure the LabVIEW EXE to run as a service, so it runs on the PC startup, before any user logs in.

Step 2 would be to use .NET to register for the event "Microsoft.Win32.SystemEvents.SessionSwitch" found in the "System" .NET selection.

Steps 3 (and on...) are then to do something when the callback VI assigned to that registered event fires.
