CVI provides functions for getting system information, such as hard drive space, windows version, system memory information, computer name, screen saver, etc. These functions are in the Programmer's Toolbox under "System Configuration". It sounds like you are actually looking for device information though, on individual boards and devices in the system. We do not have native CVI functions for retrieving device configuration information. I don't know of anyway in Windows SDK programming either to get that kind of information.
