Syntax_Error

How do I show the current time on the form in a label, and update it every second or maybe every minute???

I put "lblTime.Text = DateTime.Now" into a OnClick sub, but that only works when I click it... how do I get it to change every few seconds, or minute?????

also How can I at the same time on another label make a timer that counts up continuously from when the application loads?

thanks
