Subject: Re: upgrading a VB6 Class to Dot Net, then exposing it back to VB6
via Com Interop - there has to be an easier way
I don't have all the details in front of me, but VB.NET provides the
interface behind the scenes if you add the relevant attributes. You
can use one attribute (ComClass I think) that does all the work, or a
combination that allows more settings.
Copying from my current code: (The ComVisible attribute is instead of
making the whole assembly visible to COM which FxCop dislikes.)
<ComVisible(True)> _
<ProgId("Alternate.ProgId")> _
<Guid(SomeClass.ClassId)> _
Public NotInheritable Class SomeClass
''' <summary>
''' An explicit GUID to be used for this class's CLSID.
''' </summary>
''' <remarks></remarks>
<ComVisible(False)> _
Public Const ClassId As String =
"1234d5c8-83e2-484b-b7dd-f87e2e4567e3"
'Public Const InterfaceId As String =
"56789b7d-8677-4dc5-8682-8421a8901c77"
'Public Const EventsId As String =
"123fab6a-b957-4c73-9f0f-f06794c21d23"
As implied by the comments you can specify the InterfaceId and
EventsId as well if needed, especially using ComClass.
