title: Verfiying the network connection using Qt 4.4
body: <p>I have an application which runs a tool that requires network connection. Now my aim is to check whether the user has a network connection, if he don't have one, i can straight away display an error without proceeding further. If he has, he can continue working with my application. So my basic need is to check whether the user has a network connection or not. How i can achieve through Qt 4.4? I am using Windows XP.</p>
