I think this question has been asked before (possibly by me ) but here goes anyways:

I have an old LLBL adapter project (version 1.0.2005.1) for .net 2.0 used on one database. I now have a new database and I want to use adapter version 2.6 for .net 3.5.

So, in my program I want to be able to reference both the 1.0.2005.1 and 2.6 entities.

Can I do that? If so, how?

Thanks,

Fishy

As long as your LLBLGen generated components from each version have sufficiently different namespaces and names such that there are no clashes you should have no trouble referencing both sets.

I tried adding the 2.6 reference and I get the following error:

A reference to 'LLBLGen Pro .Net 2.0+ ORM Support Classes Library' could not be added. A reference to the component 'SD.LLBLGen.Pro.ORMSupportClasses.NET20' already exists in the project.

Is there a way of getting around this?

Thanks

Hi Fishy.. IMHO, I think that is not possible. What not just upgrade? or.. please elaborate more on what you are trying to do.

I tried updating in the past and ran into issues (which I don't remember ).

But, it's a new day and I will start the upgrading process.

Thanks,

Fishy.

I get the following error after I upgrade:

'Find' is not a member of 'MedfordSchoolDistrict.Elementary.GradeBook.LLBL.HelperClasses.EntityCollection'.

I could not find a resolution. What is the correct way of doing a Find?

Thanks,

Fishy

Edit: Here is the Code:

    Public Shared Function FindGroupStudentByStudentIdent(ByVal groupStudentCollection As EntityCollection, ByVal studentIdent As Integer) As Integer
        Dim i As Integer

        i = groupStudentCollection.Find(New EntityPropertyDescriptor2(EntityFieldFactory.Create(Elementary.GradeBook.LLBL.GroupStudentFieldIndex.StudentIdent), _
          GetType(GroupStudentEntity), False), studentIdent)

        Return i
    End Function

Please use FindMatches() instead of Find().

Also you can use an EntityView

So, my new code looks like this:

    Public Shared Function FindGroupStudentByStudentIdent(ByVal groupStudentCollection As EntityCollection, ByVal studentIdent As Integer) As Integer
        Dim i As System.Collections.Generic.List(Of Integer) = groupStudentCollection.FindMatches(GroupStudentFields.StudentIdent = studentIdent)

        If i.Count > 0 Then
            Return i(0)
        Else
            Return -1
        End If

    End Function

I haven't tested it, but does this look correct?

Thanks

From my humble VB experience I think your code looks fine.
