title: Age calculation using current year
body: <p>I am a VB.NET beginner and i would like to ask how one can calculate age of a person if only the year of birth is entered in a text box in a form. I am supposed to use the current year minus the year of birth but i don't really have the code.
  here is the problem : there is a text box named txtdob in a form where the user is required to enter his/her year of birth. I need a code that determines the age of the user using the current YEAR and the year of birth entered.</p>
