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.

To avoid having to draw the form needed for this exercise, right-click on the name of your project in Solution Explorer then choose Add --> Existing Item... (you can also press SHIFT + ALT + A to do the same thing).

 Choose only the file called frmHobsonsChoice.cs in the above folder to import it into your project, then edit Program.cs to make this the default form.  When you run your application, you should now see this:

List of dates in combo box

Surely there's no choice?


Attach code to the button so that when you click on it you see the longest name in a message box (you can get this by looping over all of the items to find the longest):

Message box showing longest name

There was a clue in the title of the folder containing the form ...


You may find the following lines of code useful to refer to or crib!

// read the combo box items into an array

string longestName = "";

foreach (string possibleDate in cmbDate.Items)

When you've got everything working, close down the form.
