You should watch the 'Erel Teaches' series of videos, especially this one. What you want is at about 4 minutes if my memory serves me correctly (I've posted this answer before). Anyway you should first watch this whole video, then you should watch the other videos too. They are all extremely informative and you WILL learn new programming techniques and the correct way to implement your code.
