 Hello ThinkGeo,

Using Google Overlay Switcher, we had implemented GoogleEarth Hybrid View and ThinkGeo view  on Web application (to switch Google /ThinkGeo maps vice versa), and we registered free key from google website.I don't know how to achieve same on WPF application?? For each PC,  do I need to get key from google ?? I have no idea...

 In Web there is a lot of control using JavaScript and/or JSON scripting API .So, Do you have same rich functionality and classess implemented on WPF Google Overlay' ? Appreciate,  if  you can send any sample working application

 Hello thinkgeo,

Will someone respond to my question??

 No problem...I can understand. Can you provide any sample application on WPF application???how about registration keys on WPF application and how this works on WPF application???

 Srikanth,

The sample code is below, you don't need to use registration key, but if you have, you can pass into construtor of GoogleMapLayer as parameter.

 wpfMap1.MapUnit = GeographyUnit.Meter;
            wpfMap1.CurrentExtent = new RectangleShape(-10000000, 10000000, 10000000, -10000000);
            LayerOverlay worldOverlay = new LayerOverlay();
            GoogleMapsLayer worldLayer = new GoogleMapsLayer();
            worldOverlay.Layers.Add("WorldLayer", worldLayer);

            wpfMap1.Overlays.Add("WorldOverlay", worldOverlay);
            wpfMap1.Refresh();

Thanks,
