            catch (SqlException ex)
            {
                for (int i = 0; i < ex.Errors.Count; i++)
                {
                    errorMessages.Append("Index #" + i + "\n" +
                        "Message: " + ex.Errors[i].Message + "\n" +
                        "Error Number: " + ex.Errors[i].Number + "\n" +
