               //wait till beginning of loading next page 
               int waittime = 100000;
               int counter = 0;
               while (true)
               {
                   loadStatus = webBrowser1.ReadyState;
                   Application.DoEvents();

                   if ((counter > waittime) || (loadStatus == WebBrowserReadyState.Uninitialized) || (loadStatus == WebBrowserReadyState.Loading) || (loadStatus == WebBrowserReadyState.Interactive))
                   {
                       break;
                   }
                   counter++;
               }

               //wait till the page get loaded.
               counter = 0;
               while (true)
               {
                   loadStatus = webBrowser1.ReadyState;
                   Application.DoEvents();

                   if (loadStatus == WebBrowserReadyState.Complete)
                   {
                       break;
                   }
                   counter++;
