Microsoft HTML Help

April 2000

Microsoft® HTML Help is the standard help system for the Windows platform. Authors can use HTML Help to create online help for a software application or to create content for a multimedia title or Web site. Developers can use the HTML Help API to program a host application or hook up context-sensitive help to an application. As an information delivery system, HTML Help is suited for a wide range of applications, including training guides, interactive books, and electronic newsletters, as well as help for software applications.

HTML Help offers some distinct advantages over standard HTML, such as the ability to implement a combined table of contents and index and the use of keywords for advanced hyperlinking capability. The HTML Help compiler (part of the HTML Help Workshop) makes it possible to compress HTML, graphic, and other files into a relatively small compiled help (.chm) file, which can then be distributed with a software application, or downloaded from the Web.

HTML Help consists of an online Help Viewer, related help components, and help authoring tools from Microsoft Corporation. The Help Viewer uses the underlying components of Microsoft Internet Explorer to display help content. It supports HTML, ActiveX®, Java™, scripting languages (JScript®, and Microsoft Visual Basic® Scripting Edition), and HTML image formats (.jpeg, .gif, and .png files). The help authoring tool, HTML Help Workshop, provides an easy-to-use system for creating and managing help projects and their related files.
