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.

The folder shown above contains a text file called Threats.txt

Create a new form which:

  • creates a new list to contain the names of the threats;
  • opens the text file shown above for reading;
  • reads through it line by line, adding each line to the list you've created;
  • sorts the resulting list; then
  • sets it to be the data source of the list box.

After running your program, you should see something like this:

List of threats

It doesn't matter what your form looks like, as long as the list is created OK.


Close your application down, and contemplate what your list would look like!
