How to create a new recurring meeting that has exceptions by using CDOEX in Visual C# (310558)

MORE INFORMATION

1. Start Microsoft Visual Studio .NET or Microsoft Visual Studio 2005.
2. On the File menu, click New, and then click Project.
3. Under Visual C# Projects, select Console Application.
   
   Note In Visual Studio 2005, click Visual C# under Project Types.
   
   In Visual Studio .NET, Class1.cs is created by default. In Microsoft Visual Studio 2005, Program.cs is created by default.
4. Add a reference to Microsoft CDO for Exchange 2000 Library (CDOEX). To do this, follow these steps:
   1. On the Project menu, click Add Reference.
   2. On the COM tab, click Microsoft CDO for Exchange 2000 Library, and then click Select.
      
      Note In Visual Studio 2005, you do not have to click Select.
   3. In the Add References dialog box, click OK to accept your selections.
   4. Click Yes if you receive a message to generate wrappers for the libraries that you selected.
   Note Collaboration Data Objects for Exchange 2000 Library is supported only when you use COM Interop.
5. Follow the previous steps to add a reference to the Microsoft ActiveX Data Objects 2.5 Library.
6. In the code window, replace all the code with the following sample code:

   using System;
   
   namespace Samples
   {
   	class Class1
   	{
   		static void Main(string[] args)
   		{
   			try 
   			{
   			CDO.Appointment oApp = new CDO.Appointment();
   
                               // TODO: Replace the Exchange server name and UserAlias with your own.
   			string sURL = "http://<ExchServer>/Exchange/<UserAlias>/calendar";
   
   			ADODB.Connection oCn = new ADODB.Connection();
   			oCn.Provider = "exoledb.datasource";
   
   			oCn.Open(sURL, "", "", 0);  
   			if(oCn.State == 1)
   			{
   				Console.WriteLine("Connection Successful");
   			}
   			else
   			{
   				Console.WriteLine("Connection Failed");
   			}			
   						
   			CDO.Configuration iConfg = new CDO.Configuration();
   			ADODB.Fields oFields;
   
   
   			oFields = iConfg.Fields;
   			oFields[CDO.CdoCalendar.cdoTimeZoneIDURN].Value = CDO.CdoTimeZoneId.cdoPacific;
   
   			// Set Meeting Organizer.
   			// TODO: Change the e-mail address to your own e-mail address.
                               oFields[CDO.CdoConfiguration.cdoSendEmailAddress].Value = "someone@example.net";	
   			oFields.Update();
   
   			oApp.Configuration = iConfg;
   			oApp.StartTime = Convert.ToDateTime("10/11/2001 10:00:00 AM");
   			oApp.EndTime = Convert.ToDateTime("10/11/2001 11:00:00 AM");
   			oApp.Location = "Office";
   			oApp.Subject = "Test: Create Meeting in C#";
   			oApp.TextBody = "Message body of test message...";
   
   			// Add the New Recurring Meeting
   			// every Thursday, starting today, and then run three times.
   			CDO.IRecurrencePatterns iRPatters = oApp.RecurrencePatterns;
   			CDO.IRecurrencePattern iRPatter = iRPatters.Add("Add");
   			iRPatter.Frequency = CDO.CdoFrequency.cdoWeekly;
   			iRPatter.Interval = 1;    // 1 hour from 10 to 11
   			iRPatter.DaysOfWeek.Add(4);  // Every Thursday.
   			iRPatter.Instances = 3;
   
   
   			// Specify Exceptions.
   			CDO.IExceptions iExceps = oApp.Exceptions;
   			CDO.IException iExcep;
   			// Delete.
   			iExcep = oApp.Exceptions.Add("DELETE");	
   			iExcep.RecurrenceID = Convert.ToDateTime("10/11/2001 10:00:00 AM");
   			// Modify.
   			iExcep = oApp.Exceptions.Add("MODIFY");	
   			iExcep.RecurrenceID = Convert.ToDateTime("10/18/2001 10:00:00 AM");
   			iExcep.StartTime = Convert.ToDateTime("10/17/2001 10:00:00 AM");
   			iExcep.EndTime = Convert.ToDateTime("10/17/2001 1:00:00 pM");
   
   			// Add attendees.
                              // TODO: Change e-mail address to your own attendee.
   			CDO.IAttendees iAtdees = oApp.Attendees;
   			CDO.IAttendee iAtdee = iAtdees.Add("someone@example.net");
   
   			CDO.ICalendarMessage iCalMsg = (CDO.ICalendarMessage)oApp.CreateRequest();
   			iCalMsg.Message.Send();
   			
   
   			// Save to the Events Calendar.
   			oApp.DataSource.SaveToContainer(sURL, null, 
   				ADODB.ConnectModeEnum.adModeReadWrite, 
   				ADODB.RecordCreateOptionsEnum.adCreateNonCollection, 
   				ADODB.RecordOpenOptionsEnum.adOpenSource, 
   				"", "");
   
   			oCn.Close();
   
   			oApp = null;
   			oCn = null;
   			oFields = null;
   			}
   			catch (Exception e)
   			{
   				Console.WriteLine("{0} Exception caught.", e);
   			}			
   		}
           }
   }
