Hi All,
In Forms 5.0, (Windows 98) Can you please suggest me how to pass a parameter from a menu to a form. I will tell u situation. I have a menu in which there are different options. In that menu, i have two options called Vendor Update and Vendor delete. If i click either of those options, i have to open a single form. But based on the parameter like UPDATE or DELETE, i have to do some validations in the form.
Can anyone suggest APPROPRIATE solution for this. Its very urgent
Thank you

One option is to use global variables
In Menu Item Code of Vendor Update
:global.UPD_OR_DEL := 'UPDATE';
call_form('vendor.fmx'...............);
erase('global.UPD_OR_DEL');
In Menu Item Code of Vendor delete
:global.UPD_OR_DEL := 'DELETE';
call_form('vendor.fmx'...............);
erase('global.UPD_OR_DEL');
in vendor form the action can be referred as
:global.UPD_OR_DEL to do the validations.
Second option is to use Parameters
In Menu Item Code of Vendor Update
declare
pl_id ParamList;
BEGIN
pl_id := Get_Parameter_List('action');
IF NOT Id_Null(pl_id) THEN
Destroy_Parameter_List( pl_id );
END IF;
pl_id := Create_Parameter_List('action');
Add_Parameter(pl_id,'action',TEXT_PARAMETER,'UPDATE');
call_form('vendor.fmx',no_hide,do_replace,pl_id,no_query_only,pl_id);
DESTROY_PARAMETER_LIST(PL_ID);
END;
Second option is to use Parameters
In Menu Item Code of Vendor Delete
declare
pl_id ParamList;
BEGIN
pl_id := Get_Parameter_List('action');
IF NOT Id_Null(pl_id) THEN
Destroy_Parameter_List( pl_id );
END IF;
pl_id := Create_Parameter_List('action');
Add_Parameter(pl_id,'action',TEXT_PARAMETER,'DELETE');
call_form('vendor.fmx',no_hide,do_replace,pl_id,no_query_only,pl_id);
DESTROY_PARAMETER_LIST(PL_ID);
END;
In the form vendor a parameter should be created in the object navigator with the name "action".
the value :parameter.action can be used for validations
