Hi Experts,

I'd like to create a winform with a timer value and it will save the timer value e.g. start value = 23 hours 60 min 60 sec to a text file.

1. click button and it saves the start value as text to a .text file.
2. A timer on the winform will count down to 0 (in time to the windows system clock (real-time)

(The reason for the text file is so that if I close the winform for xx hours and open it again, it will resume countdown and deduct the passed time and adjust the timer.) then save the current time to the text file.

3. When the timer gets to 0 it stops counting and performs an action.
4. If I click the button again, it starts the process all over again, but saves an alternative filename.. e.g. textfile2.txt; and so on...

Hope this isn't too difficult.

I've played with timers but this is out of my league.

Regards,
Roberto

You need to look at using TimeSpan objects and deduct the DateTime.Now value from your saved DateTime.
