C# Project
In this project we will be building a digital clock in C# using Visual Studio. By the end of this project we will have very simple digital clock that you can enhance and upgrade on your own.
To create a digital clock we will need Timer which will help us in updating the time every second.
To create a Timer in C# we have to write
Timer t = new Timer();
After we have our timer t, we need to set the timer interval to 1 second which is 1000 millisecond.
t.Interval = 1000;
After the interval is set, we need an event handler that will execute some code every second. For this we will need a method.
private void t_Tick(object sender, EventArgs e) { }
Now we need to add the event handler method t_Tick to our timer t. For this we will write
t.Tick += new EventHandler(this.t_Tick);
Well its pretty easy! Just write
t.Start();
