1you can use a global timer for whole project which can be in a static class or you can use MDI winforms .1st one is simpler than 2nd if you're a beginnerLucifer– Lucifer2018-06-12 06:41:24 +00:00Commented Jun 12, 2018 at 6:41

I would suggest to manage the program from module Program.cs and then launch forms from that parent module. Then, you can have, as suggested a timer in a Global static classCarles– Carles2018-06-12 06:45:25 +00:00Commented Jun 12, 2018 at 6:45

You can pass instance of timer as a parameter to next form constructor, so you can carry forward same time in next form.
Lets take an example:
You have first question on From1 and on Submit function you want to show next form something like this:
public class Form1
{
...
public void submit()
{
...
//Here you are calling form2
//Pass timer instance a parameter to form2
Form2 form2Instance = new Form2(timer);
form2Instance.Show();
}
}

Prasad can you post an example of that one!
Put your timer as a static member in a form that inherits from Form. All other high level forms should inherit from the one with the timer.

If you want to share timer across different forms, you have two options.
1: pass timer instance between forms
var myTimer = new Timer(...);
//here this means form1
this.MyTimer = myTimer;
form2.MyTimer = myTimer;
2: make a timer instance static (and public) so you can access it from everywhere
public static Timer MyTimer = new Timer(...);
