There are two types of user in particular that will benefit from this book:
You have some experience of Access, but have not begun to learn VBA. You have spent a bit of time familiarizing yourself with the different Access objects - tables, forms, queries, reports - and may have used macros to achieve a little automation. You have not really programmed before, but are keen to learn how to tap the power that VBA offers.
You have programmed a little with another language, perhaps Visual Basic or some of the scripting languages (such as VBScript or JScript), and need a primer on VBA and its use within Access. Even if you know a little VBA you'll find plenty in the book to keep you occupied.
