Insert a Calender in oracle 6i forms

How can you set a calendar on oracle forms 6i
=====================================
Step 1: Download forms 6i demos with library from

https://googledrive.com/host/0B5DZvtSmSXRITmREUTQ1ZmxYb0U/forms6idemos.zip

copy the stndrd20.olb and calendar.pll file from forms6idemos\win32\pmbf\6_0_8_8\demo\forms location and past it

Desired forms directory

Step 2: Add stndrd20.olb desired form module and expand the library then duble click into the COMPONENTS tab
drag and drop the calendar into the module.When a message arise then press copy.

Step 3: In the programm unit Add a package spacification named date_lov and write the following code:
================================================================================
package date_lov is
last_lov_date number(2);
current_lov_date date;
date_lov_return_item varchar2(80);

lov_title varchar2(80);
lov_auto_confirm boolean;
lov_auto_skip boolean;

weekend_highlight boolean;
weekend_day1 number;
weekend_day2 number;

procedure display_cal(display_date in date);
procedure date_click;
procedure get_date (display_date in date,
return_item in varchar2,
v_x_pos in number := 0,
v_y_pos in number := 0,
v_title in varchar2 := 'Date List of Values',
v_ok in varchar2 := 'OK',
v_cancel in varchar2 := 'Cancel',
v_highlight in boolean := TRUE,
v_autoconfirm in boolean := FALSE,
v_autoskip in boolean := FALSE);
end;

Step 4: In the programm unit Add a package body named date_lov and write the following code:
==========================================================================

package body date_lov is

-- display the labels in American style with Sunday as
-- the first day of the week

go_item(date_lov.date_lov_return_item);
if date_lov.lov_auto_skip = TRUE then
next_item;
end if;
end if;
end date_click;
end;

Step 5: Create a text item(if needed) and push button in the form that will execute the calendar.
in the push button write the following code in WHEN-BUTTON-PRESSED trigger
===========================================================================================================================

declare
xp number;
yp number;
begin
xp:=get_item_property('from_date',x_pos);
yp:=get_item_property('from_date',y_pos);
date_lov.get_date(sysdate,'EMPLOYEE.from_date',240,60,'From Date','OK','Cancel',TRUE,FALSE,FALSE);
END;

[note:change block name like here employee is block and item name like from_date;]

compile the form and run...........
