Access added a new data type in the 2007 version--the Attachment type. We are currently working on a WinForms application with .NET 3.5 (C#) that uses an Access 2007 databas
I've been struggling to try and do this same thing. There is a reference you can include in your project to "Microsoft.Office.Interop.Access.Dao" that will get you the Recordset2 and Field2 Interfaces, but no implementation classes.

I was not able to get this working in C#, so I moved on to a different solution. I would love to know how to do this though if someone figures it out.
