Hide objects to certain users

Question

Hi,
I want to hide or deactivate some of the fields(objects) in the form module
for certain users .Please help me if anybody knows it.
Thanks in advance

Answer 1

create a table with the name of all your users,
then a table with your security-roles (similiar to db-roles, but in your own table)
create an intersection-table between those 2 tables
each row in the table means: this user has the permission to see the object.
then create a function Allowed_to_See (P_Obejctname IN VARCHAR2) RETURN Boolean
in that function you select from the intersection table, if the actual user has the permission to see the object P_Objectname. Then Return TRUE, else FALSE.
In the form you use the WHEN-NEW-FORM-INSTANCE to check those items :
IF Allowed_to_See ('blockname.My_secure_Item') THEN
set_item_property ('blockname.My_secure_Item', VISIBLE, Property_True);
END IF;
Default for this item is Visible = False
try it
