Who this book is for
This book is primarily for Microsoft Visio users or developers who want to know how to use and extend the validation rules in Microsoft Visio 2013 Professional edition. There are some rulesets available out of the box, but the capability can be added to many sorts of diagramming, whether they are process flows, network cabling drawings, or risk dependency diagrams, for example. This is not a Visio SmartShape developer manual or a Visio automation guide, although these subjects are explored when relevant for writing validation rules, but it does shed light on the possibilities of this new powerful feature of Microsoft Visio 2013. This book will be an essential guide to understanding and creating structured diagramming rules, and will add developer tools that are not in the out-of-the-box product.
