This book will teach the reader how to customize the user interface for Microsoft Office applications, including Access, Excel, and Word, using RibbonX.   The authors show how to customize the Ribbon using VBA, XML and macrosconcentrating on:        XML development for Ribbon customization;        VBA to add functionality to the custom UI.  And, since macros and VBA will trigger Windows security settings, they also cover the relevant aspects of security, such as trust centers and digital certificates.  The chapters are filled with real-world code examples that readers can immediately apply.   (Many procedures will apply to all major Office apps; where they don't, the authors highlight the differences.) The book also includes appendices of reference material so that readers can quickly see the correct names or groups, tabs and other necessary objects in the ribbon and application hierarchies.
