  Generating Outlook Calendar with timezone difference

  Feb 28, 2011 01:26 PM|LINK

  Hi:

  I am able to generate a calendar successfully however, if someone from a different timezone accepts it does not adjust to their timezone.  Does anyone know how I can compensate for this in the following code?

  TrainingStart = Convert.ToDateTime(ReturnValue4);
  
              TrainingEnd = TrainingStart.AddMinutes(30);
  
              //Initialization
              MemoryStream mStream = new MemoryStream();
              StreamWriter sw = new StreamWriter(mStream);
              sw.AutoFlush = true;
  
              //Header
              sw.WriteLine("BEGIN:VCALENDAR");
              sw.WriteLine("VERSION:2.0");
              sw.WriteLine("PRODID:-//Flo Inc.//FloSoft//EN");
              sw.WriteLine("BEGIN:VEVENT");
  
              //Body
  
              sw.WriteLine("DTSTART:" + TrainingStart.ToString("s"));
              sw.WriteLine("DTEND:" + TrainingEnd.ToString("s"));
              sw.WriteLine("LOCATION:" + Location);
              sw.WriteLine("X-ALT-DESC;FMTTYPE=text/html:" + Description.Replace("\n", " "));
  
              sw.WriteLine("SUMMARY:" + Subject);
  
  
              //Footer
              sw.WriteLine("PRIORITY:" + Priority);
              sw.WriteLine("END:VEVENT");
              sw.WriteLine("END:VCALENDAR");
  
  
  
              //Make it Downloadable
              Response.Clear();
              Response.AppendHeader("Content-Disposition", "attachment; filename=Add2Calendar.ics");
              Response.AppendHeader("Content-Length", mStream.Length.ToString());
              Response.ContentType = "html/x-vCalendar";
              //Response.ContentType = "application/download";
              Response.BinaryWrite(mStream.ToArray());
              Response.End();
              sqlcon.Close();

  Unfortunately this issue is still unresolved.  This is the code i have now.  A clause for each Timezone however they are off by 1 hour.  Not sure what i am missing.

  if (trainingtimezone.Equals("(EST)"))
              {
     
                  //Initialization
                  MemoryStream mStream = new MemoryStream();
                  StreamWriter sw = new StreamWriter(mStream);
                  sw.AutoFlush = true;
  
                  //Header
                  sw.WriteLine("BEGIN:VCALENDAR");
                  sw.WriteLine("VERSION:2.0");
                  sw.WriteLine("PRODID:-//Flo Inc.//FloSoft//EN");
                  sw.WriteLine("BEGIN:VEVENT");
  
                  //Body
               
                  sw.WriteLine("DTSTART;TZID=US/Eastern:" + TrainingStart.ToString("s"));
                  sw.WriteLine("UTC-OFFSET:-0500");
                  sw.WriteLine("DTEND;TZID=US/Eastern:" + TrainingEnd.ToString("s"));
                  sw.WriteLine("LOCATION:" + Location);
                  sw.WriteLine("X-ALT-DESC;FMTTYPE=text/html:" + Description.Replace("\n", " "));
  
                  sw.WriteLine("SUMMARY:" + Subject);
  
  
                  //Footer
                  sw.WriteLine("PRIORITY:" + Priority);
                  sw.WriteLine("END:VEVENT");
                  sw.WriteLine("END:VCALENDAR");
  
  
  
                  //Make it Downloadable
                  Response.Clear();
                  Response.AppendHeader("Content-Disposition", "attachment; filename=Add2Calendar.ics");
                  Response.AppendHeader("Content-Length", mStream.Length.ToString());
                  Response.ContentType = "html/x-vCalendar";
               
                  Response.BinaryWrite(mStream.ToArray());
                  Response.End();
  
              }
