C# exam application timer cheating issue [closed]

timer

I have made an exam application in C# that has a timer, while taking exam suppose the candidate keeps on pressing the windows' minimize button (without releasing the mouse) at 1 minute and 30 seconds, the time pauses even if the candidate keeps on pressing the mouse for 10 minutes, but when the mouse is released the time resumes from the very second where it was paused i.e. 1 minute and 30 seconds. I want the timer to be continued without any pauses.

What timer component are you using? System.Windows.Forms.Timer or System.Threading.Timer?

I suspect the S.W.F.Timer uses SetTimer API call which uses window messages which would explain what you are seeing, a threaded timer would be better.

You could also just use a thread, store a DateTime.UtcNow and every 100ms or something in the thread, get another DateTime.UtcNow and check the TimeSpan for the elapsed time.

Use the System.Threading.Timer class because that is supposed to work independently from windows messages
