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 frmHobsonsChoice.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:

List of dates in combo box

One choice stands out ...


Attach code to the button to loop over all of the items in the combo box (see the sample code below for help on this) and display the longest:

Message box showing longest name

The best things in life?  "To crush your enemies, see them driven before you, and to hear the lamentation of their women."


You may find the following lines of code useful as a guide:

'read the combo box items into an array

Dim longestName As String = ""

Dim possibleDate As String

For Each possibleDate In cmbDate.Items

That's it!
