QUESTION 1
You work as a software developer at Certkiller .com. You develop an application that
includes a Contact Class, which is defined by the following code:
Public Class Contact
Private name As String
Public Event ContactSaved()
Public Property Name()
Get
Return name
End Get
Set(ByVal Value)
name = Value
End Set
End Property
Public Sub Save()
‘Insert Save Code.
RaiseEvent ContactSaved()
End Sub
End Class
You create a form named MainForm. This form must include code to handle the
ContactSaved event raised by the Contact object. The Contact object will be
initialized by a procedure named CreateContact.
Which code segment should you use?
A. Public Class MainForm
Private oContact As New Contact()
Private Sub HandleContactSave()
‘Insert event handling code.
End Sub
Private Sub CreateContact()
oContact.Name = “Certkiller”
oContact.Save()
End Sub
End Class
B. Public Class MainForm
Private WithEvents oContact As New Contact()
Private Sub HandleContactSave()
‘Insert event handling code.
End Sub
Private Sub CreateContact ()
oContact.Name = “Certkiller”
oContact.Save()

End Sub
End Class
C. Public Class MainForm
Private WithEvents oContact AsNew Contact()
Private Sub HandleContactSave()
Handles oContact.ContactSaved
‘Insert Event handling code.
End Sub
Private Sub CreateContact ()
oContact.Name = “Certkiller”
oContact.Save()
End Sub
End Class
D. Public Class MainForm
Private WithEvents oContact As New Contact()
Private Sub HandleContactSave() _
Handles oContact.ContactSaved
‘Insert event handling code.
End Sub
Private Sub CreateContact ()
Dim oContact As New Contact()
oContact.Name = “Certkiller”
oContact.Save()
End Sub
End Class
Answer: C
Explanation:
Not D: Public Class Main Form
Private WithEvents oContact As New Contant()
Private Sub HandleContactSave() Handles oContact.ContactSaved
‘Insert event handling code.
End Sub
Private Sub CreateContact()
Dim oContact as New Contact()
oContact.Name = “Certkiller”
oContact.Save()
End Sub
End Class
The problem with this code is that the Class Level oContact that is specified WithEvents,
is hidden by the Method Level variable of the same name inside the CreateContact
procedure. Therefore the save method call will not have any effect as there is no event
handler for the method level variable.
There fore the correct answer is C
