Operation must use an updateable query?

Jeg får denne fejl:
Exception Details: System.Data.OleDb.OleDbException: Operation must use an updateable query.

Min kode:

Dim strConn As String
            Dim strSQL As String
            strConn = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & HttpContext.Current.Server.MapPath("db/Data.mdb")
            strSQL = "INSERT INTO tblNews (SubmitDate, Title, BodyText) VALUES ('" & strDate & "', '" & strTitle & "', '" & strBody & "')"

            Dim objConn As New OleDbConnection(strConn)
            Dim objCmd As New OleDbCommand(strSQL, objConn)

            objConn.Open()
            objCmd.ExecuteNonQuery()
            objConn.Close()

Nogen der kan se hvad der er galt?
