This book introduces the Microsoft Visio drawing and diagramming software environment and provides programmatic information about using Visio as a development platform, including details about using formulas to design Visio SmartShapes symbols that model real-world objects and behavior. It also contains information, tips, and techniques for using the Microsoft Visual Basic® and Visual C++® development systems and the Visual Basic for Applications (VBA) programming environment to incorporate Visio as a component in other applications. Because Visio is a graphics product, the book includes many illustrations for shape developers, as well as code examples and samples.
