The book has alot of typos, i.e. missing parantheses in code examples, missing function arguments etc. I've found it to be somewhat troublesome, but you should be able to go to msdn online to figure out the typo. For example on page 487 the move method requires 4 arguments when anyone of the optional 3 are there but he only includes 2. There is also a missing parantheses there as well.
This book does not go into ADO in any kind of depth that is needed. The Murach book, 'VB6 beginner to database pro' does ADO much better. There does seem to be a complete lack of ADO books for VB6. I imagine there are alot for VB.net. If you want this book, you will need another book to learn ADO programming in VB6. Database manipulation is what many people use VB for. However this lack of ADO depth may be because the book went to press before MS finalized ADO (just a guess there).
Don't get me wrong, I thought this book was very informative and helpful, the fact that ADO is not covered in depth is a definite drawback. Also the code examples don't include every example from the book, just the complete programs. There were many code snippets that you could put in blank vb6 project to illustrate something that were not in the downloadable code from osborne. I would have preferred a CD to downloading as well.
8/20/2003 - I hadn't realized this before becuse the book does not cover it at all, but there is a complete lack of coverage of interface classes. I had to go to a new riders book MCSD TRAINING GUIDE: VISUAL BASIC 6 EXAMS for a good discussion of this. Even the mspress book is somewhat confusing on this topic. If you can get this book used than do that. Don't pay full price though, especially since the binding seems to come apart after alot of use.
