Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Press CTRL + D to add the file called frmOldestPerson.vb from the above folder into your project (or right click on the project and choose to add it as an existing item). 

Change your project's properties to make this the default form for your project.  When you run your project, you should see this:

Form to show oldest person

Clicking on the button should display the name of the person whose date of birth is earliest.

 

See below for how to achieve this!

Write code for the Show name of oldest person button to loop over the array set up in code-behind and find and display the person with the earliest date of birth:

The oldest person

You should find that Bob has the earliest date of birth.

 

You can use Split (using a comma as a separator) for each array item to retrieve each person's date of birth.

You're now an array guru!
