please check your update statement(i will start programming with database very soon but before right now , i am reading Book on SQL).
i saw there the correct syntax for update statement is:

UPDATE enroll SET username='" & textbox1.Text & "' where ID=" & _UserId

, is used when you are gonna update multiple fields.
