Using timers in vb

Question

I do not understand how to utilize the timers in vb.net I want to make a simple program where when I press a button the timer starts and the label changes it's number every second until 60 seconds have passed. I think I should put this in the button event

Timer1.Start()

But I am unsure of what to do from there. How do I go about doing this?

Answer 1

Well Timer1.Start() starts the timer, but you need to declare how often the timer ticks.

Timer1.Interval = 1000

will make the timer tick every 1000 miliseconds, or 1 sec. The actions that you want to happen for the timer go in the Timer_Tick event handler.

In order to allow the label to increment you could use a global variable:

Public Class MainBox

Dim counter As Int

Private Sub Form_Load(sender As System.Object, e As System.EventArgs)
    Timer1.Interval = 1000
    Timer1.Start()
End Sub

Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) HandlesTimer1.Tick<action>
    counter = counter + 1
    label1.Text = counter
End Sub
