From VBA to Visual Basic

I have successfully used VBA for sometime but I am having trouble with
the transition in some cases to VB6

In particular is the example shown for usinging ILocateCommandEvents in
the Copy Element Example

Sub RunCopyElement()
    CommandState.StartLocate New clsCopyElementCommand
End Sub

etc

This example works fine in VBA but in VB6 I get the error message
" Procedure declaration does not match description of event or
procedure having the same name"


What do I need to do to get it to fire?
