I have created a simple application which will tell the user what is IP address of the user and also the country name and country is also displayed. For this I have used the free web service which you can find here they have other free services as well.
For this application I have used the Image and the TextBlock control in my application and the web service I have used from the here. The code is simple one I have used one class which is used as the view model for the main user control ( with the name MainPageViewModel and which has one property of MyIPAddress of type GeoIP type. which is available when you add the service reference) and the one converter class which is listed in the List 1.The code in the List 1 is simple one here I have passed the country code to the converter and then by concatenating path with the country code and the png extension I return the image path of the country flag. if the country code is empty the default image will be return which you can see in the Image 1. And if the country code and the other information is successful then you can see the output as shown in the Image 2.
Note: If your country flag is not displayed please let me know with the country code so that I can update it on my example as well.
I have only uploaded the web side not the Silverlight application. You can download the source code from here and you can open the What Is MyIPTestPage page in IE or in your web browser to check the application.
