Overriding the default logon screen in Forms 4.5

Do anybody have tried to use own logon screen by overriding the default logon screen. Asking user to type in the connection string is a bit "urgy".

In the previous version of forms (v4.0). I can successfully override it by making some code in the on-logon trigger. I call the logon built-in in the on-logon trigger. It worked.

But when I use the same trick in v4.5. Problem comes that when user type in a wrong password the first. The second time, he type in a right password. Then he can logon virtually. Once, the program run to some code that ask the database for data, general protection fault appears!!!
