Online help

From Wikipedia, the free encyclopedia

Online help is topic-oriented, procedural or reference information delivered through computer software. It is a form of user assistance. Most online help is designed to give assistance in the use of a software application or operating system, but can also be used to present information on a broad range of subjects. When online help is linked to the state of the application (what the user is doing), it is called context-sensitive help.

Online help is created using help authoring tools. It is delivered in a wide variety of formats, some proprietary and some open-standard, including:

Hypertext Markup Language (HTML), which includes HTML Help, HTML-based Help, JavaHelp, and Oracle Help
Adobe Portable Document Format (PDF)

[edit] Microsoft help platforms

Microsoft develops the platforms for delivering help systems in the Microsoft Windows operating system.

Microsoft QuickHelp - Ralph Walden joined Microsoft in 1987 and wrote an online help system for MS-DOS and OS/2 called QuickHelp. Ralph was also primarily responsible for WinHelp and HTML Help 1.x.
The DOS, OS/2 and Windows help command.
Microsoft WinHelp (.HLP) - Based on the Rich Text Format, this was the industry standard for Windows 3.1 and Windows 95/NT. The popular Windows Help program (WinHlp32.exe) was included with all Windows operating systems from Windows 3.0 until the Windows XP operating system. However, the help engine is not included with Windows Vista and is only available as a download. [1] (click Help Engine Support)
Microsoft Compressed HTML Help (.CHM) - Based on compiled HTML and other data such as images and JavaScript. HTML Help 1.0 was released in 1997. In 2006, it was available from Microsoft as HTML Help 1.4.
HTML Help 2.0 - In 2001, Microsoft announced plans for a wide release of HTML Help 2.0. This platform was developed by Microsoft and shipped in 2002 as the help format for Visual Studio .NET, MSDN Library and Technet products, but Microsoft announced it had cancelled plans to make the format publicly available.
AP Help 1.0 - Assistance Platform Help is the new generation of online help being developed for and shipped with Windows Vista. It will not be made publicly available as an authoring platform for other software vendors. It will be used by Microsoft, OEMs, and certain corporations.
