Excerpt of article text...
This article illustrates how to add a help window to any Macintosh or Windows application written in REALbasic. To demonstrate, we'll construct a single window RB application called QuickHelpRB.
To complement the source code presented here, you can download a zip file with the QuickHelpRB source code file, QuickHelpRT.app (Mac), QuickHelpRT.dll (Win), and QuickHelp.qhlp (example help file).
To present help information from an RB app, the developer includes the QuickHelpRT viewer and a help file with their application. On the Mac, you can send Apple Events to load a help file, change topics, etc. On Windows you can declare an external method and send commands to the help viewer running as a DLL.
The help file itself is a platform neutral XML formatted text file that contains all the topics, pictures, links, index, etc. The viewer executable presents a help window to the application user complete with contents, index, navigation buttons, search, and other features you'd expect in a professional help system. The example help file, QuickHelp.qhlp was authored using QuickHelp from Excel Software.
