Oracle Forms

hi folks,

i'm in the process of developing online help system using Robo Help for the application which we have developed on Orace Forms 6i. i have created Windows .hlp files using RoboHelp Classic Edition, but i
dono how to invoke the help files by pressing the F1 key from the application.

i have created map ids in RoboHelp and i've given the map ids in the corresponding fields hint properties
of the form, and i'm calling the help fiels using the following code in the KEY-HELP trigger at form level. is this right ?

DECLARE
M_MAPID PLS_INTEGER;
BEGIN
M_MAPID := GET_ITEM_PROPERTY(:SYSTEM.CURSOR_FIELD,HINT_TEXT);
WIN_API_SHELL.WINHELP('E:\ORION9\ROBO\EMP\EMP.HLP',M_MAPID,WIN_API.HELP_CONTEXT,FALSE);
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
END;

if so what is the use of 'Help Book Topic' field property in Forms, please help !

thanks in advance !
