Microsoft HTML Help is a browser-specific Help solution optimized for delivering online Help for applications running on Windows 95, 98, NT, or 2000. When Microsoft released HTML Help in 1997, the plan was for HTML Help to replace WinHelp. Although Microsoft quickly adopted HTML Help for most of its own products, the rest of the industry was slower to adopt the new technology. Now, however, HTML Help is widely used for locally installed online Help for applications that run under Microsoft Windows.
To create HTML Help, authors create topic files in HTML format. The topic files, together with a few project files and ActiveX controls, are compiled using Microsoft's HTML Help compiler. The compiler produces a .chm file, which is then distributed to users of the Help system. Help authors can use a variety of tools to produce Microsoft HTML Help, including RoboHelp, Doc-To-Help, ForeHelp, HDK, and WebWorks Publisher.
In order to view the .chm file, users must have installed both Internet Explorer (version 3.02 minimum, 4.0 or later for full functionality) and the HTML Help system components. chm files cannot be viewed in any version of Netscape Navigator.
Note: To view the sample HTML Help system, you must have IE4 or later and the HTML Help components installed on your machine. Choose "Open this file from its current location" in the dialog box that appears after you click this link. If you do not have IE4+ and the the HTML Help components, you will not be able to view the sample HTML Help system.
Note: If you are creating Microsoft HTML Help systems, you will benefit from having at least basic familiarity with core Web technologies like HTML and CSS. This is true even if you are using a Help authoring tool.
