how can we help you if you yourself don't know what's your problem..

Thanx Accepted.

what is wrong with my codes

1) I don't see any definition for SqlCon.
2) No definition for b_id.
3) This DReader = SqlCmd.ExecuteReader should be DReader = SqlCmd.ExecuteReader().
4) Line 11, this DateTimePicker1.Text should be DateTimePicker1.Value.And the list goes on . . . .
