I am currently writing a book named Data Mining in Excel VBA.doc. You can buy this word file, including the test data, test reference tables and programs for €5, - and read the book, exercise with the book and the programs and give me some feedback so I can improve my book (Hopefully I can also use the premature book for a hands-on course on Excel VBA). Since it is not complete and is not graphically perfect, I cannot ask more money for it, not yet... It was sent to QUE publishing, but was not accepted for publishing. It might be that they already have a lot of books on Excel VBA: http://www.quepublishing.com/search/index.aspx?query=excel+vba Still, I think my book has some advantages over other books, therefore the idea for me is to improve my document with user (your?) feedback and offer a relatively cheap book in the beginning (now). In the end I would like to publish the fully revised book. There is a comparison with Excel VBA code recorded by the macro recorder, regular programming code, and object oriented code using Office equal or less than version 2003 and from Office 2007 and so on. Thanks a lot for your help. All the best, Tim
