A solution to the problem is given in the following example.

						End If
						End Set
						End Property

   Public Sub New(ByVal name As String, _
                  ByVal color As String, _
                  ByVal height As Single)
      m_name = name
      m_color = color
      MyClass.height = height
   End Sub
End Class

Then you have added the Property statement, which is somewhat similar to that of a ...
