How do you Raise an Error?

[mendhak]

In a class I'm writing, if a bad value is sent to a property, I'd like to raise an error, so that when the class is being used, a Try...Catch...Finally block can work with it.

Would I use an Err.Raise statement in here:

Property LastName() As String
            Get
                LastName = m_sLastName
            End Get
            Set(ByVal Value As String)
                If Value = "MENDHAK" Then
[b]'Err.Raise ???[/b]
 
                Else
                m_sLastName = Value
                End If
 
            End Set
        End Property
