When working with Web applications, the predefined "HELP" event is associated to an object's help. This means that when the "HELP" event is triggered in a Web object, a new window in the browser will open, showing the object's help in its HTML format. To include help in a web application, we must generate it as HTML, as by default browsers can't interpret the CHM format.
To indicate the directory where the Help (HTM) files are located, the Help File Base URL Property has been created, under the group Web Information at generator level. Said directory, which can be indicated as absolute or relative, is where you must place the help files generated in HTM format corresponding to each object.
Note: The "HELP" event must be assigned to a button, an image, a textblock, or a read-only edit box.
