For parameterized queries using OleDb you have to use the syntax

sSQL = "INSERT INTO faculty (FacultyName, Course, Address, Image)" _
     & "  VALUES(?,?,?,?)

and you have to ensure that the parameters are added in the same order as they appear in the fields list. If you use SqlDb then you can use the @param format and add the parameters by name in any order.

same error sir:((

When you insert a new record you don't have an existing FacultyID value. I suppose you've declared FacultyID as Identity/Autonumber value so you shouldn't try to insert in that field anything.

Move line 37 between lines 29 - 30. After that your code accesses FacultyID only when the record exists and therefore that field does have a value.


ssql="INSERT INTO faculty ( FacultyName, Course, Address, Image)VALUES(@FacultyName, @Course, @Address, @Image)"
try this Or if u want to new code to strore image in to database then i ill give u new code
