Can someone explain this line of code to me please?

this.myTimer.Tick += new System.EventHandler(this.myTimer_Tick);

System.Windows.Forms.Timer Control is essentially a new thread that notifies you on regular intervals. Its notification happens through an event called "Tick".

So when you say mytimer.Tick += new EventHandler(this.mytimer_Tick)

you are subscribing to that event. You say, "when your time (interval) has elapsed, I want to know about it"

When timer ticks - it calls

private void mytimer_Tick(object sender, EventArgs e)
{
//and this is where you do the work that happens every interval (Timer Tick)
}

The other thing that might be causing confusion is the += operator. These two lines are equivalent.

a = a + b;
a += b;

In the case of events, this operator subscribes you to the event. You can also remove yourself with the -= operator.
