Cannot stop Windows Service from example

[BrilllianD]

I make custom Windows Service from example, register by "sc" cmd, run it.
Then when trying to stop this, Windows raise error message "failed to stop service ... this service did not return an error".

I have try to find some code in this repo, but cannot find example how to handle it.

P.S.
thanks for any help

Ran into this myself earlier, the solution is to set the program state to ServiceState::Stopped either during the event handler or shortly after returning from the event handler.

See this example which spawns a thread to set the service to ServiceState::Stopped in response to a ServiceControl::Stop request:

    let status_handler = Arc::new(Mutex::<Option<ServiceStatusHandle>>::new(None));
    
    let event_handler = move |control_event| -> ServiceControlHandlerResult {
        let to_return = match control_event {
            ServiceControl::Stop | ServiceControl::Interrogate => {
                ServiceControlHandlerResult::NoError
            }
            _ => ServiceControlHandlerResult::NotImplemented,
        };
        
        if let ServiceControl::Stop = control_event{
            let status_handler_clone = status_handler.clone();
            std::thread::spawn(move || {
                std::thread::sleep(Duration::from_millis(800));
                if let Ok(Some(h)) = status_handler_clone.lock().as_deref(){
                    let _ = h.set_service_status(ServiceStatus{
                       service_type: ServiceType::OWN_PROCESS,
                       current_state: ServiceState::Stopped,
                       controls_accepted: ServiceControlAccept::empty(),
                       exit_code: ServiceExitCode::Win32(0),
                       checkpoint: 0,
                       wait_hint: Duration::default(),
                       process_id: None 
                    });
                }
                //exit(0); 
            });
        }
        
        to_return
    };

Windows will also automatically shut down the service after this, so no need to invoke std::process::exit

Please see the example https://github.com/mullvad/windows-service-rs/blob/main/examples/ping_service.rs#L135-L144

Also MSDN outlines the service lifecycle which only progresses if you report the service status to the SCM.
