The best programming book that I have ever read.
I was already an MS Access developer; this book was invaluable in my learning VB6 and ADO (as well as better development techniques). I would not have gained my MCP (VB6 Desktop Applications) without the skills gained from Koop, Prince and Murach.
Three years after buying the book, it is still my first reference point for VB, VBA and ADO.
