AutoCAD .NET :: VB / Map 3D - Reading Object Data Tables From DWG Inside Database

Would you have a solution to accessing ODTables for a dwg object only loaded into memory? I have 1000+ dwgs that I want to return a string with the names of the various ODTable names for auding purposes that I would prefer to just side load rather than full load for performance reasons.

 I'm attempting to use something like this (which works fine on an open drawing):

 Public Function ReturnOBJData(acObjIDIn As ObjectId, intOffset As Integer) As String   
 'Don't forget that table is 0 based offset so....plan accordingly    Dim strRet As String = ""    
Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument    
Dim acDb As Database = acDoc.Database    Dim acEd As Editor = acDoc.Editor
[Code] .......

In a fashion along the lines of

Public Function GetTables(strFileIn As String) As List(Of String)    
Dim lstReturn As New List(Of String)    
Dim acMapApp As MapApplication = HostMapApplicationServices.Application    
Dim acActiveProject As Project.ProjectModel = acMapApp.ActiveProject    
Dim acTableList As Tables = acActiveProject.ODTables    Dim acTable As ObjectData.Table   

[Code] ....

The problem is that I can't seem to link the ODTables object off of the memory database object. In this sample, the msgbox always returns a count of 0 where I would expect it to be in the range of 1-4.
