Since the publication of Windows Interface Guidelines in 1995, the Windows user experience has continued to evolve. The new releases--Windows 98, Windows 2000, and Internet Explorer 5 require precise documentation so developers can understand them and optimize their work accordingly. This book delivers the only print version of official Microsoft guidelines for creating well designed, visually and functionally consistent Windows user interfaces (UIs). It includes both mandatory specifications and practical design suggestions, and will be extensively cross-referenced. New to this edition will be a top-level summary that will call out common UI mistakes and point developers to the sections of the book that describe optimal user experience.
