Hi, I'd say the Windows native Wifi library seems like a starting point. I've never used it in LV but it works in other languages, so you will only need to match the data types - https://msdn.microsoft.com/en-us/library/windows/desktop/ms706749(v=vs.85).aspx wlanapi.dll is in System32 (or SysWOW64). Other ways could be reusing high-level open-source library that pretty much do all the job. ManagedWifi is quite famous for that: - https://managedwifi.codeplex.com/ --Eric

Correct, although this isn't actually relevant for XControls, as they do actually run even if the VI is not running. Another term for "reserved" would be "entering run mode" and it happens when the hierarchy the VI is in starts executing and the run arrow changes from white to something else which isn't broken or unsynced. Here's a table I did a while back and never got to use: It doesn't include all the states (like the green arrows), but it is fairly representative. The relevant states are the bottom three. This behavior can actually have consequences if you have weird code like setting val(sgnl) from another VI or if you register for an Application event like VI Activation and it's certainly relevant if your user manages to do something like double click on controls before the VI closes, as the events are saved in the queue even if the VI isn't running and will be processed the next time the VI is called and the event structure executes.
