Here's the third part of a submission from  Jake. Combined with part one and part two, I must say, we've got quite an interesting system: 

If correct_answer_nbr3 <> user_answer_nbr3 Then

 update_test(tmpLastQuestionAnswered, correct_answers_qty3)

 If Right(CStr(question_nbr3), 1) = "2" Then
  msg = "Your answer is Incorrect. The correct answer is '" & Trim(strCorrectAnswer) & "'"
 Else
  msg = "Your answer is Incorrect. The correct answer is '" & Trim(strCorrectAnswer) & "'" & Chr(13) & Chr(10) _
    & "Because this is a PreTEST you must go throught the Course and take the PostTest"
 End If

 msgbox.Show(msg, "Answer Results", Windows.Forms.MessageBoxButtons.OK, _
       Windows.Forms.MessageBoxIcon.Error, Windows.Forms.MessageBoxDefaultButton.Button1, _
       Windows.Forms.MessageBoxOptions.ServiceNotification)

 If Right(CStr(question_nbr3), 1) = "1" Then
  Dim returnURL As String = CType(ViewState.Item("ReturnURL"), String)
  ViewState.Clear()
  Response.Redirect(returnURL)
  Exit Sub
 End If
Else
 msg = "Your Answer '" & Trim(strCorrectAnswer) & "' is CORRECT"
 msgbox.Show(msg, "Answer Results", Windows.Forms.MessageBoxButtons.OK, _
       Windows.Forms.MessageBoxIcon.Information, Windows.Forms.MessageBoxDefaultButton.Button1, _
       Windows.Forms.MessageBoxOptions.ServiceNotification)

End If

For those not into .NET Windows Forms, msgbox.show brings up a modal dialog box, halting code execution until it is closed. It's like a javascript alert() for Windows.
