Furthermore, this book reveals many important and little documented points tied to Excel VBA, ranging from range and cells to many critical points like external data access with true database programs, which are even not dealed in some self-proclamed 'expert' books, like Walkenbach's. Besides, it exhibits many trips and tricks that allow fast, clean programs and avoir many troubles by grouping all points linked to a particular problem.

Third, the writting is not terse: with irony, and a great amount of objectivity, qualities which seem to evaporate in Walkenbach and others (which very often sound like a Microsoft ad), it clearly explains and demonstrates the limits and bugs of Excel VBA.

Fourth, the companion CD Rom is truly useful, loaded with many pratical and real-life examples and solutions. Again, Walkenbach, after saying virtually every page the HE is the author, the creator and so forth, with its constant I-do-this mentality, provides a software wich is not usable since the reader has to send a coupon card!

Finally, this is the book to have for truly mastering Excel VBA, without pain but with efficiency.
