Open the Age Solution (Age Solution.sln) file contained in the VB2015\Chap02\Age Solution folder. If necessary, open the designer window. The application allows you to enter the year you were born and the current year. When it is coded, the Calculate button will calculate your age by subtracting your birth year from the current year. Lay out and organize the interface so that it follows all of the GUI design guidelines you have learned so far. Lock the controls on the form. Code the Exit button’s Click event procedure so it ends the application. Save the solution and then start the application. Verify that the tab order is correct. Also verify that the access keys work properly. Use the Exit button to end the application. Close the solution.
