    * through the command line.
    */

         //Process a = rt.exec("c:\\Program Files\\Internet 
Explorer\\iexplore http://www.microsoft.com/ms.htm");
         Process a = rt.exec(path + "http://www.microsoft.com/ms.htm"); 
      }	
      catch(Exception e) 
      {

      } 
   }

      RegKey rkey = new RegKey(RegKey.CLASSES_ROOT,

      return rkey.getStringValue("");
   }
