I have DNN 4.5.5.
I develop in Visual Web Developer.
I recently upgraded the iFrame module from 3.2.3 to 4.3.0.

Before the upgrade I got no errors or warnings when I performed a build on my web site.  After the iFrame upgrade, I get the following warning when I run a build:

"Access of shared member, constant member, enum member or nested type through an instance; qualifying expression will not be evaluated."


This warning appears in the file \App_Code\IFrame\Controller.vb at line 199, column 40.

An excerpt from the Controller.vb file is shown below.


193        ''' <summary>
194        ''' Gets the single instance of the current <see cref="DataProvider"/>.
195        ''' </summary>
196        Protected ReadOnly Property DataProvider() As DataProvider
197            Get
198                If Me._dataProvider Is Nothing Then
199                    Me._dataProvider = DataProvider.Instance
200                End If
201                Return Me._dataProvider
202            End Get
203        End Property


The warning is flagged at DataProvider.Instance in line 199.

I'm not a programmer of your level, so I don't understand the warning, and I don't know if something related to the iFrame will not work as a result.  Does something else need to be installed?  How do I fix this?

Thanks,
SK

Thanks, Stefan.

If I have to ignore the warning I will, but the engineer in me would like to find out if this is just a glitch with VWD, or a problem resulting from performing an upgrade.  I have some very important stuff going on in several iFrames, so if this is a potential site crasher, I need to know now.

I'm not really a programmer, so please forgive me if I sound stupid regarding the following text.

So... I looked for a class or a namespace called either:

DotNetNuke.Modules.IFrame.DataProvider.Instance

or

DotNetNuke.Modules.IFrame.DataProvider


There was nothing close in the Controller.vb file.  What I did find, related to the iFrame, was:

Imports DotNetNuke.Modules.IFrame.Domain
Imports DotNetNuke.Modules.IFrame.Data


Now VWD recommends a possible solution to line 199.  It suggests changing:

Me._dataProvider = DataProvider.Instance

to

Me._dataProvider = Data.DataProvider.Instance


In the namespace DotNetNuke.Modules.IFrame.Data, in the file DataProvider.vb, there is a property called Instance, shown below.


#Region "| Properties |"

        ''' <summary>
        ''' Gets the single instance of the <c>DataProvider</c> object.
        ''' </summary>
        Public Shared ReadOnly Property Instance() As DataProvider
            Get
                If _provider Is Nothing Then
                    _provider = CType(Reflection.CreateObject(ProviderType, ProviderNamespace, ""), DataProvider)
                End If
                Return _provider
            End Get
        End Property

#End Region




If I try the suggested change, the warning goes away, but since I don't really understand what this change means, or if it is even correct, I didn't save the changes.

What do you think?  Is there something different between my DNN 4.5.5 and your DNN 4.8.1 that is causing this warning?

Thank you, Sir.  My IDE and I feel much better.
