Hi all

I am looking for a simple explanation of what this is all about. It is not described in Michael Washington's otherwise excellent Module Developoment documentation. It is mentioned but not explained in Professional DotNetNuke 4 chapter 8 page 282. And the blog posts I have found all seem to assume that you understand it.

So could someone please point me in the right direction or explain it here.

kind regards

Geoffrey

Hi Michael

Thank you for a fast response.

Yes, I had seen this blog but what I am looking for is a worked example, like you gave us for IPortable, IActionable and I Searchable in your Module Developer's manual. Maybe it is all so trivial thet there is nothing to say about it but from my point of ignorance I don't know what code to put where and why.

Can you point me to a good model in one of the core modules, perhaps?

Kind regards

Geoffrey

Geoffrey,

IUpgradeable is suggested not to be used, Joe Brinkman explains why here.  If that doesn't deter you, you'll be looking for something like this (from the Blog module):

        Public Function UpgradeModule(ByVal Version As String) As String Implements Entities.Modules.IUpgradeable.UpgradeModule
            Dim message As String

            Select Case Version
                Case "03.01.20"         ' first version as DotNetNuke sub project
                    message = message & " In Custom Upgrade Version " & Version & " - "
                    Dim _CustomUpgrade As New CustomUpgrade
                    message += _CustomUpgrade.UpgradeNewBlog()
                    message += " - " & _CustomUpgrade.UpgradeForumBlog()
            End Select
            Return message

        End Function
