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 frmOldies.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:
When someone clicks on the button shown, they should see their name, age and status (see below for how this is calculated) displayed back to them.
Add the following properties to your application:
| Property | Type | Contains |
|---|---|---|
| PersonName | Read-only | The name of the applicant |
| Age | Read-only | The age of the applicant |
| Status | Read-only | Senior citizen if over 65; adult if over 18; child otherwise |
| IfEligible | Read-only | Whether this person can join (they must be over 65 to do so) |
Attach the following code to the button on the form:
'print out details of this person (must reference
'System.Diagnostics namespace at top of code)
Debug.WriteLine("PROPERTY VALUES")
Debug.WriteLine(" ")
Debug.Indent()
Debug.WriteLine("Name = " + personName)
Debug.WriteLine("Age = " + age.ToString())
Debug.WriteLine("Status = " + status)
If IfEligible Then
Debug.WriteLine("Eligible")
Else
Debug.WriteLine("Not eligible")
End If
Debug.Unindent()
Here's what your output should look like when you enter a couple of people's details:
What you might see after two people at opposite ends of life have typed in their details.
