Sending meeting request through Exchange server API

Here we can send a meeting request through exchange server .

Here is the code for creating the  meeting request.

        ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2007_SP1);

        exchangeService.Credentials = new WebCredentials("<user name>", "<password>", "<domain>");

        exchangeService.Url = new Uri("<Exchange server url.>");

 

Here is the method in C#  which creates the meeting request.

public static void CreateMeetingRequest(string ownerEmail, string subjectText, string messageBody, string location, DateTime start, DateTime end, DataTable attendees)

        {

            try

            {

                SPSecurity.RunWithElevatedPrivileges(delegate()

                {

                    ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2007_SP1);

                    exchangeService.Credentials = new WebCredentials(EXCHANGE_USER_NAME, EXCHANGE_PASSWORD, EXCHANGE_DOMAIN);

                    exchangeService.Url = new Uri(EXCHANGE_URL);

                    Appointment appointment = new Appointment(exchangeService);

                    appointment.Subject = subjectText;

                    appointment.Body = new MessageBody(BodyType.Text, messageBody);

                    appointment.Start = start;

                    appointment.End = end;

                    appointment.Location = location;

                    appointment.ReminderMinutesBeforeStart = 30;

                    foreach (DataRow drow in attendees.Rows)

                    {

                        appointment.RequiredAttendees.Add(new Attendee(Convert.ToString(drow["Email"])));

                    }

                    appointment.Save();

                });

            }

            catch (ServiceRequestException ex)

            {

                throw new ApplicationException("Error: " + ex.Message);

            }

            catch (WebException ex)

            {

                throw new ApplicationException("Error: " + ex.Message);

            }

        }

Rename Title field in share point List

Here is the code to rename the Title field. Because the Title is the default field in custom list.


                    SPField f = listCollection[<Guid of List>].Fields["Title"];
                    f.Title = "Name";
                    f.StaticName = "Name";
                    f.Update();



Note: in SPQuery field you should use Title field. because still internal name is Title.

if (CheckListExist(webObject.Lists, lookupListName) == false)
{
// Throw error if the list doesn't exists.
throw new ApplicationException(string.Format("{0}'s list doesn't exists!", lookupListName));
}
SPList lookupList = webObject.Lists[lookupListName];
