Accessing Project 2003 from .NET 1.1

Question

I am working on a windows app that interacts with PWA 2003, Project 2003, and data pulled from our HR system.  I need to be able to get access to the cost tables within Project, unlike most data which is available through PWA, these appear to be stored in a large binary field within the SQL Server db.  Anybody else had to deal with anything like this?  I have Project plugged into my app as a COM reference but am failing to be able to get access to those tables on a code - based level.
