I have some problems about Visual Basic now. The problem is how can i display the D.O.B. report using Crystal Report? What wrong if got "Object reference not set to an instance of an object" error message box display? If D.O.B. declare as Date in db, can i display the report based on month? Because now i face with the problem which i need to key in the actual D.O.B., I means if i want to search the report that just born on Jan and the database is set as 21/01/1988, then i need to type 21/01/1988 to display the report. It can't display all Jan D.O.B. report.
