Examples

The following example demonstrates how to handle StatusChanged events.

using System;
using System.Device.Location;
namespace ShowStatusUpdates
{
    class Program
    {
        static void Main(string[] args)
        {
            ShowStatusUpdates();
        }

        static void ShowStatusUpdates()
        {
            GeoCoordinateWatcher watcher = new GeoCoordinateWatcher();
            watcher.Start();

            watcher.StatusChanged += new EventHandler<GeoPositionStatusChangedEventArgs>(watcher_StatusChanged);

            Console.WriteLine("Enter any key to quit.");
            Console.ReadLine();
        }

        static void watcher_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e)
        {
            switch (e.Status)
            {
                case GeoPositionStatus.Initializing:
                    Console.WriteLine("Working on location fix");
                    break;

                case GeoPositionStatus.Ready:
                    Console.WriteLine("Have location");
                    break;

                case GeoPositionStatus.NoData:
                    Console.WriteLine("No data");
                    break;

                case GeoPositionStatus.Disabled:
                    Console.WriteLine("Disabled");
                    break;
            }
        }
    }
}

Imports System.Device.Location

Module GetLocationEvent

    Sub ShowStatusUpdates()
        Dim Watcher As GeoCoordinateWatcher
        Watcher = New GeoCoordinateWatcher()
        watcher.Start()
        AddHandler Watcher.StatusChanged, AddressOf watcher_StatusChanged

        Console.WriteLine("Enter any key to quit.")
        Console.ReadLine()
    End Sub

    Sub watcher_StatusChanged(ByVal sender As Object, ByVal e As GeoPositionStatusChangedEventArgs)
        Select Case e.Status
            Case GeoPositionStatus.Initializing
                Console.WriteLine("Working on location fix")
            Case GeoPositionStatus.Ready
                Console.WriteLine("Have location")
            Case GeoPositionStatus.NoData
                Console.WriteLine("No data")
            Case GeoPositionStatus.Disabled
                Console.WriteLine("Disabled")
        End Select
    End Sub

    Public Sub Main()
        ShowStatusUpdates()
    End Sub
End Module

Remarks

The StatusChanged event is raised on the same thread that the GeoCoordinateWatcher object was created on.
