[DllImport("user32.dll", SetLastError = true)] 
    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")) 
        { 
         temp+=ie.LocationURL + " "; 
        } 
       } 
      } 
     } 
     if (programName.Equals("firefox")) 
     { 
      DdeClient dde = new DdeClient("Firefox", "WWW_GetWindowInfo"); 
      dde.Connect(); 
      string url1 = dde.Request("URL", int.MaxValue); 
      dde.Disconnect(); 
      temp = url1.Replace("\"","").Replace("\0",""); 
     } 
     url = temp; 
     return temp; 
    }
