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.

Create a new form which:

  • creates a new list to contain threats to world peace;
  • opens the text file called Threats.txt in the folder above, for reading; and
  • reads through it line by line, adding each line to the list you've created

Here's what you should see after running your program:

List of threats

Here we've used a list box to hold the imported threats, sorted into alphabetical order, but it doesn't matter how you choose to display the information.

 

When you've got this working, you could spend an idle moment wondering how you would change this list to make it more realistic.  For example, should beetroot be on the list too? 

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
