we are creating Online Exams Module.Just lke any other online exams on other real sites. The Case is the user can attempt any question within 3 minutes.after 3 minutes,the next question automatically disappears and another question comes on the page. We also want to show times in Minutes as a clock just like any other online exams. My issue is that how can i show time on each page and how can i calculate every 3 minutes. I know there is Timer/Thread class in c# for web application.But i dont know how they can efiicently work. Or there is any other better method to do it.Even i have tried to it with timers in Asp.net 2005 .and My code was this:- System.Timers.Timer time1=new timer();time1.AutoReset=true;time1.Interval=60000;time1.Elapsed+=new ElapsedEventHandler(time1_Elapsed);and event was suchprivate void time1_Elapsed(object source,System.Timers.ElapsedEventArgs e){////////////Any function}But this code is not properly working..and i seem my application does not showany result or seems AMBIGIOUS. Plaese help me with example or code.Or write some better way.I am not very perfect at it.
