DxfCode.Operator doesn't exist for Autodesk Map?

[swagues]

So, I'm trying to build a filter to select all text in a document, but the version of

Autodesk.AutoCAD.DatabaseServices.DxfCode that comes with Autodesk Map doesn't seem to have the Operator code included in it.

How do I access operators with Autodesk Map?

I might be missing something here.  This method from Hallex in the .net forum selects all text.  This is generic autocad - not specific to any vertical product (Autodesk.AutoCad.EditorInput namespace in the accoremgd assembly).

    ' Imports System.Collections.Specialized
    Private Function ExtractText() As StringCollection
        Dim txtcoll As New StringCollection
        Dim doc As Document = Application.DocumentManager.MdiActiveDocument()
        Dim db As Database = doc.Database
        Dim ed As Editor = doc.Editor
        Try
            Using tr As Transaction = db.TransactionManager.StartTransaction
                Dim res As PromptSelectionResult
                Dim filterList(,) As Object = New Object(,) {{-4, "<or"}, {0, "text"}, {0, "mtext"}, {-4, "or>"}} '' etc
                Dim tvs(filterList.GetUpperBound(0)) As TypedValue
                For i As Integer = 0 To filterList.GetUpperBound(0)
                    tvs(i) = New TypedValue(Convert.ToInt32(filterList(i, 0)), filterList(i, 1))
                Next
                Dim filt As SelectionFilter = New SelectionFilter(tvs)
                res = ed.SelectAll(filt)
                If res.Status <> PromptStatus.OK Then
                    Return Nothing
                End If
                For Each sobj As SelectedObject In res.Value
                    Dim ent As Entity = tr.GetObject(sobj.ObjectId, OpenMode.ForRead)
                    Dim txt As DBText = TryCast(ent, DBText)
                    If txt IsNot Nothing Then
                        txtcoll.Add(txt.TextString)
                    End If
                    Dim mtxt As MText = TryCast(ent, MText)
                    If mtxt IsNot Nothing Then
                        txtcoll.Add(mtxt.Contents)
                    End If
                Next
            End Using
        Catch exs As System.Exception
            ed.WriteMessage(exs.Message & vbLf & exs.StackTrace)
            Return Nothing
        Finally

        End Try
        Return txtcoll
    End Function
