            sch.Formatting = Formatting.Indented;
            sch.Namespaces = false;
try
                {
                    sch.WriteStartDocument();

                    sch.WriteStartElement("", "Schedules", "");

                    sch.WriteStartElement("", "Scheduler", "");
                    sch.WriteString(subjTextbox.Text.ToString());
                    sch.WriteEndElement();

                    sch.WriteStartElement("", "FileName", "");
                    sch.WriteString(textFile.Text.ToString());
                    sch.WriteEndElement();

                    sch.WriteStartElement("", "Date & Time", "");
                    sch.WriteString(date.ToString());
                    sch.WriteEndElement();

                    sch.WriteEndElement();
                    sch.Flush();
                }
                catch (Exception e1)
                {
                    MessageBox.Show(e1.Message);

                }
