Can we bypass the Oracle login screen?

The first thing that the user sees when using run form is the Oracle logon prompt asking them for their username, password, and database to connect to. You can bypass this screen or customize it by displaying your own logon screen. Eg:

            ON-LOGIN

            declare

                uname varchar2(10);

                pass  varchar2(10);

            begin

                uname := 'username';

                pass  :='password';

                logon(uname, pass||'@connect_database');

            end;
