Their DB referenced in chapter 3...

you are going to restore a copy of the customized AdventureWorksVSTO database, available from the Codeplex site containing the sample code and related online materials associated with this book (http://www.codeplex.com/obasales).

...isn't in their archive on codeplex, and it isn't in the archives off wrox. Can someone post this?

The .bak file located in the chapter 07 materials is the database backup. Let me know if you have trouble restoring the backup of the database to a local db.

Have a great day,
Bill Sheldon
