    static extern IntPtr FindWindowEx(IntPtr parentHandle,
    IntPtr childAfter, string className, IntPtr windowTitle);

    [DllImport("user32.dll", CharSet = CharSet.Auto)]
    public static extern int SendMessage(IntPtr hWnd,
        int msg, int wParam, StringBuilder ClassName);

    private static string GetURL(IntPtr intPtr, string programName, out string url)
    {
        string temp=null;
        if (programName.Equals("chrome"))
        {
            var hAddressBox = FindWindowEx(intPtr, IntPtr.Zero, "Chrome_OmniboxView", IntPtr.Zero);
            var sb = new StringBuilder(256);
            SendMessage(hAddressBox, 0x000D, (IntPtr)256, sb);
            temp = sb.ToString();
        } 
        if (programName.Equals("iexplore"))
        {
            foreach (InternetExplorer ie in new ShellWindows())
            {
                var fileNameWithoutExtension = Path.GetFileNameWithoutExtension(ie.FullName);
                if (fileNameWithoutExtension != null)
                {
                    var filename = fileNameWithoutExtension.ToLower();
                    if (filename.Equals("iexplore"))
