Create a form called frmDateOfBirth containing a DateTimePicker control, to allow someone to enter their date of birth:

Visual Basic 2010 exercise - Variables and data types (image 1)

Oh to be this young ...

Attach code to the Show Age button to:

  • Use the DateTimePicker's Value property to set the value of a a variable to hold the date entered
  • Creates a variable to hold today's date (use System.DateTime.Today)
  • Creates a variable to hold the difference between the two in days (using the DateDiff function)

When you run your application, you should see a message similar to this one:

Visual Basic 2010 exercise - Variables and data types (image 2)

Take the difference in years between the date entered and today's date

That's it!
