Publication number: 20070220429Abstract: A method and system are disclosed for configuring and generating a customized help user interface. The disclosed method and system are based on a technique that includes incorporating a reference to a help content source in a customizable metadata layer of a plurality of metadata layers. Each metadata layer of the plurality of metadata layers includes respective instruction sets that define the help user interface in accordance with a layer precedence. The help content source is then stored as part of a collection of discrete sources of help content. When the help user interface is later rendered, the layer precedence determines whether the help content source referenced in the customizable metadata layer or one or more of the other discrete sources of help content in the collection is utilized by a interface-rendering engine that generates the help user interface.Type: ApplicationFiled: March 17, 2006Publication date: September 20, 2007Applicant: MICROSOFT CORPORATIONInventors: Arif Kureshy, Muhammad Alam

Publication number: 20070220428Abstract: A method and system is disclosed for generating a help interface to present static help content and customized help content for an application. Help content data is accessed to define the static help content and a control command to support incorporation of the customized help content. The control command is implemented to determine a configuration of the application, and a user context is determined based on a user characteristic and the application configuration. The customized help content is then resolved based on the control command and the user context. In some cases, a help system may include a help viewer module or program in communication with a computer-readable memory storing the help content data. The help viewer may then render the help interface based on the static help content and customized help content resolved from the control command, the application configuration, and other aspects of the user context in which it is presented.Type: ApplicationFiled: March 17, 2006Publication date: September 20, 2007Applicant: MICROSOFT CORPORATIONInventors: Arif Kureshy, Gary Syck, Muhammad Alam
