VB Class Implementation with Pseudo Inheritance

This is an interesting example and simply shows that inheritance is sort-of possible using Visual Basic. There is another method using the Implements keyword. However, the implements keyword requires a lot of duplication of code. I am sure that someone out there has a better way of implementing inheritance in Visual Basic. I would like to know how to do inheritance properly if possible. Please let me know.

RecordSet Class

Option Explicit

Public Sub MoveFirst()
'
End Sub

Public Sub MoveLast()
'
End Sub

Public Sub MovePrevious()
'
End Sub

Public Sub MoveNext()
'
End Sub

Search Module

Option Explicit

Public Sub MoveFirst(TheRecordset As CRecordset)
    TheRecordset.MoveFirst
End Sub

Public Sub MoveLast(TheRecordset As CRecordset)
    TheRecordset.MoveLast
End Sub

Public Sub MoveNext(TheRecordset As CRecordset)
    TheRecordset.MoveNext
End Sub

Public Sub MovePrevious(TheRecordset As CRecordset)
    TheRecordset.MovePrevious
End Sub
