Why would one declare both a Let and Set property accessor in VB6

问题

In an older project I found a property declaration in a class module which looks like the following...

Public Property Get DrawObject() As Object
    Set DrawObject = m_obj
End Property
Public Property Let DrawObject(obj As Object)
    Set m_obj = obj
    Draw
End Property
Public Property Set DrawObject(obj As Object)
    Set m_obj = obj
    Draw
End Property

I would like to know why the DrawObject property has both a Let and Set accessor defined; what could be the purpose of such a declaration?

回答1:

The only reason would be to allow/support both assignment syntaxes:

set instance.DrawObject = obj

and

instance.DrawObject = obj
