Now, WinHelp is never used for new help projects. However, some legacy systems use WinHelp. WinHelp was an early type of online help for software. WinHelp runs only on Windows.
Navigation is a problem in WinHelp. The navigation is difficult to use, because a reader cannot easily view both the table of contents and the content at the same time.
According to Microsoft Knowledge Base article 917607 (http://support.microsoft.com/kb/917607), Windows Vista partly supports WinHelp. WinHelp has two formats:
- 16-bit .HLP files. The files are read with the WinHelp.exe program, which is supplied with Windows Vista.
- 32-bit .HLP files. The files are read with the WinHlp32.exe program, which is not supplied with Windows Vista.
Although 32-bit WinHelp files can be viewed in Windows Vista by downloading and installing WinHlp32.exe, Microsoft recommends that software developers change the online help to an alternative help file format, such as compiled HTML Help, HTML, or XML.
