CONTEXT-HELP-FILE attribute

(Windows only)
Specifies the path name of a help (.HLP) file associated with a dialog box, window, or session.
Return type: CHARACTER
Access: Readable/Writable
Applies to: SESSION system handle, DIALOG-BOX widget, WINDOW widget
If CONTEXT-HELP-FILE is not specified (is unknown) for a dialog box, the dialog box inherits the help file of its parent window. If the parent window's CONTEXT-HELP-FILE is also unknown, it inherits the session's help file (specified by SESSION:CONTEXT-HELP-FILE).
The full pathname of the help file should be given. The AVM does not search for the help file. The pathname can contain Unicode characters. See OpenEdge Development: Internationalizing Applications for more information about Unicode.
