A way can be to check Registry at
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\RadioManagement\SystemRadioState
(for example with RegNotifyChangeKeyValue)

@Castorix31 , is there any other way to get the airplane mode toggle event instead of a thread continuously waiting on a register key event to happen?

I tested by quickly reducing code for WinUI 3 from How to manage network connection events and changes in availability (XAML)
and I receive notifications in OnNetworkStatusChange

NetworkStatusChanged event is for when the network to which the system is connected is changed right?

I got this as the response for this wifi change thread - https://learn.microsoft.com/en-us/answers/questions/1153367/winui3-how-to-capture-wifi-change-event-in-winui3.html

was not able to try is out yet, facing some issue in implementing it in C++

Did you receive it when you switch off the wifi? because airplane mode turns off the wifi right.

Sorry had to check it out myself but facing an issue in implementing NetworkStatusChanged in c++

I just tested and I don't receive it (I'm connected to my box with an Ethernet USB cable)

But for Wifi, there are other APIs, like WlanRegisterNotification

I was able to implement NetworkInformation.NetworkStatucChanged() like this

NetworkInformation info{}; info.NetworkStatusChanged([=](...) { MessageBox(nullptr, "Something Changed!", "Network", 0); });

I received this event every time I changed the network I'm connected to. I even received it when I changed from ethernet to Wi-Fi

Hi there,

Maybe you can try this, MobileBroadbandRadioStateChangeTrigger.

Represents a trigger that indicates when mobile broadband radio state has changed. For example, this trigger activates when a mobile device transitions to or from airplane mode. This functionality is available only to mobile operator apps and UWP app given privileged access by mobile network operators.

This is a winRT API, because of my equipment, I can't help you test.
