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 frmSquares.vb from the above folder into your project (or right click on the project and choose to add it as an existing item).
The aim of this exercise is to make the following work:
The idea is that when you click on the Go! button your code should create a list, add the first ten squares to it and then display the list items in the list box as shown here.
Please turn over for how to proceed!
The first thing to do is to create a list:
'create a new list to contain the square numbers
Dim squares As New List(Of Integer)
Next, loop from 1 to 10 adding the square of each integer to the list called squares.
You can then set the data source for the listbox to be the list that you've populated:
'show this list of squares
lstSquares.DataSource = squares
When you've got this working, close down your application and any forms that you have open.
