Parameters

cFileName (Optional): Type: Usual
The file name of the help database to which this help display should be connected.
oOwnerWindow (Optional): Type: Usual
The window object which owns this help display, if any.
lWin32Processing (Optional): Type: Usual
When TRUE this will tell X# to use the standard WIN32 help processing

Remarks

X# 2.8 has added support for the use of Standard Win32 help processing which is based on the WM_HELP message since Windows95. The default VO like online help is disabled in this mode. This means, that SHIFT-F1 and mouse help don’t work. On the other hand the Windows standard help cursor is full supported and the help button on a caption bar too. See: Window:EnableHelpButton() and Window:EnableHelpCursor() Also text popups are supported only in this mode.
