Read binary file data into tables and apps

I am looking for several methods on how best to take Registry file data (binary data format) and read it into a VB.NET set of tables. I am trying to develop a program that will compare Registry entries and allow review by the user to update the local (Registry) copy or mark the master copy for updating, pending review by the master file owner/administrator. I've pretty much designed the program flow as I initially envision it, but I'm stumped by how to accomplish this read and display piece of the program.

Can anyone help?
