Information about Microsoft HTMLHelp
HTMLHelp, developed by Microsoft, is a help system that uses Hypertext Markup Language (HTML) to create locally stored technical documentation and help for application software. HTMLHelp Workshop is used to compile the content into a compressed help file with the file extension CHM.
Create application help
In a complex application a detailed application help (AppHelp) and documentation should still be provided for the user. If you are an application developer for Windows (C#, VB.net, etc.) and use Visual Studio, you can easily connect an HTMLHelp (CHM) system to your application.
Web-based help for your customers
The web-based help system (WebHelp) makes complex topics of documentation texts or image data available on the Internet that were previously not accessible or retrievable in encapsulated information systems for outsiders.
WinHelp - a former Microsoft help system
WinHelp (HLP) is available since the early '90s and has been replaced by HTMLHelp 1.x (CHM). WinHelp has not been distributed with the operating system since Microsoft's Windows Vista (codename "Longhorn").
