Visio 2003 Developer's Survival Pack

Rating:
Summary: Excellent book
Review: I have several Visio books - most are useless for developers who write VBA/VB/VC++ code for Visio automation. For those who develop for Visio, this is a must-have book. It's simply the Visio developer's bible compared to the rest. It includes sample code, appendices of events, properties and more. I wish I had known about this book before I began visio programming because it's easy to read from beginning to end and progress your skills incrementally - now I use it as a reference.
He also lets you download software tools to use - one awesome one is a VB DLL/VSL adapter. But even without the extra software this book goes into more detail and depth than any other, except the Microsoft Devloper book (which is free online). And it's a great companion to the Msoft book, and covers things it doesn't. (including highlighting the bugs)
All in all, an excellent book and the only one worth buying.
