I made it to chapter 20 and would like a copy of that file as well. After reading this post here, I googled "sampdata.mdb" and p2p.wrox.com forum threads were the first two hits!
I would also like to learn how to create a database at runtime and distribute a database application. Since the database needs to be registered with Windows I am guessing an .exe alone might not work on some Windows installs? Either way, a pointer of where a beginner can look for this (sites, books, etc) would be appreciated!
