csv file problem

what you want to do?if you have read data in buffer then must be contain data in buffer.I think some where in you code buffer have lost data.Please check it.
when i run the application first time buffer contains correct data of file but when i close and run the application again and read file data in buffer then buffer contains empty?

Are you releasing the file properly when your application closes? :)

The problem may be that you've briefly described the issue, yet have shown no code to go along with that. At this point, it could be anything. Be specific!
