Issue Details

I would like to protect my CVI application based on the MAC Address of the computer. 
How do I get the MAC Address information in LabWindows/CVI?



You can retrieve the MAC Address and other NET information by using the Win32 API library. 
There are two methods:
1. Using WMI (Windows Management Instrumentation) API . 
An example can be found here: 

2. Using the NetBIOS function from the NetAPI32.dll. 
An example can be found here:

Additional Information

The Interface to the Win32 API is a collection of import libraries, header files, help files, code samples, and utility programs for Win32 operating system development. 

The Win32 API can be added to a C programming project by including the <windows.h> header file and linking to the appropriate libraries.
