Programmatically Retrieve Windows User Name in LabVIEW

Primary Software: LabVIEW Development Systems
Primary Software Version: N/A
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I would like to build a path constant specific to the currently logged-on user.  For example, I would like to create files on the user's desktop, and the path to the desktop contains the Windows user name.  Is there a way to get the Windows user name from LabVIEW?

Solution:
One way to obtain the Windows user name is by using the System Exec function in LabVIEW.  A full list of Windows Environment Variables may be obtained by typing set at the command prompt.  To return any of the Environment Variables, use the command echo %EnvironmentVariableName%.  Use the command echo %username% with the System Exec function to programmatically get the Windows user name in LabVIEW.

Another way to obtain the Windows user name is by using the User Name property of the Application class in VI server.

Both techniques result in the same string.
