Why another book about VBA? John and I first started talking about writing a book together some time ago. As programmers and teachers of others how to program, we found that we had many similar experiences. One of which is that you can never have enough examples of how to do various things. Both of us used books written by others as well as ourselves as sources for examples in both writing new code as well as teaching others to program. Another thing we felt that many books provided was a variable perspective on how to get the job done. That is, different ways to think about how to solve problems with programs and obtain improved productivity.

And while we were discussing the merits of book and the logistics of writing one together, an opportunity was presented by Miller Freeman Inc to author one about VBA Visual Basic for Applications. Both of us had extensive experience in BASIC and programming in general thus we thought it would be fun to put one together. We were right. It was fun and we both learned a lot from each other along the way. And to increase the amount of pleasure, we switched systems along the way. We started working with VBA in AutoCAD Release 14 and ended up in AutoCAD 2000 by the time we finished. The book is written for both versions however there are features in the newer AutoCAD VBA that will not work in the earlier one. We...
