i create a form using 10g. in any circumstance db link droped and at the time client run that form, forms connecting to db and when it can't, it showing a logon screen which is default of Forms. i wrote On-Error trigger to forcefully exit from form when this error occured but its Forms default behaviour that i cannot use Exit_Form from On-Error trigger. how i can do it that user cannot see that Forms default logon screen???
