private bool LoopOverControls(bool reset, bool checkIfEmpty)

            bool results;
            foreach (Control ctrl in this.Controls)
            {
                if ((ctrl as TextBox) != null)
                {
                    if (reset == true)
                        (ctrl as TextBox).Text = "";
                    if (checkIfEmpty == true)
                        results = true;
                }
            }
            return results;
        }
