I'm not a LabVIEW guy, so I'm not going to be able to point you at the proper vi, but the string you want is located at "StationGlobals.TS.CurrentUser" to get the Current User Container that has all of the information about who is currently logged in. If you've accessed TestStand properties using LabVIEW before, then the vi you used to do that will work for this as well.
