microsoft outlook vcs/vcalendar problems

Question

User1243045096 posted
hi guys,

Need some help here, heres code snippet to save in the vcs format,

public static MemoryStream SaveToVCSFormat()
{
MemoryStream mStream = new MemoryStream();
StreamWriter sStream = new StreamWriter(mStream);
sStream.AutoFlush = true;
// Header of the Calendar event
sStream.WriteLine("BEGIN:VCALENDAR");
sStream.WriteLine("BEGIN:VEVENT");
// Body of the Calendar event
sStream.WriteLine("DTSTART:" + _startDate.ToString("yyyyMMdd\\THHmmss\\Z"));
sStream.WriteLine("DTEND:" + _endDate.ToString("yyyyMMdd\\THHmmss\\Z"));
sStream.WriteLine("LOCATION:" + _location);
sStream.WriteLine("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:" + _description);
sStream.WriteLine("SUMMARY:" + _subject);
// Footer of Calendar event
sStream.WriteLine("PRIORITY:3");
sStream.WriteLine("END:VEVENT");
sStream.WriteLine("END:VCALENDAR");
return mStream;
}

& the piece that sends it to the user

// Send it to the user
MemoryStream CalendarItem = TCalendar.SaveToVCSFormat();
Response.Clear();
Response.ContentType = "text / x - vCalendar";
Response.AppendHeader("Content-Disposition", "attachment; filename=AddInteraction.vcs");
Response.AppendHeader("Content-Length", CalendarItem.Length.ToString());
Response.BinaryWrite(CalendarItem.ToArray());
Response.End();

Now ..
This works perfectly as long as the _description string is only one line. For multple lines , string = "tralalal\rtralalallaaa", Outlook won't open the created vcs file. Throws a error.
Next ...
If I create an Calendar event in Outlook -> Save As -> Open with Notepad it looks like this

BEGIN:VCALENDAR
PRODID:-//Microsoft Corporation//Outlook 11.0 MIMEDIR//EN
VERSION:1.0
BEGIN:VEVENT
DTSTART:20060125T060000Z
DTEND:20060125T063000Z
LOCATION;ENCODING=QUOTED-PRINTABLE:test area
UID:040000008200E00074C5B7101A82E0080000000070AD630FD121C6010000000000000000100
 00000CA988CCE64F06D43AE4896ED52F782B5
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Line 1=0D=0ALine 2=0D=0ALine 3=0D=0AL=
ine 4=0D=0A
SUMMARY;ENCODING=QUOTED-PRINTABLE:testing
PRIORITY:3
END:VEVENT
END:VCALENDAR

its has alot off  " =0D=0A " characters for each new line @ Description. i think?
when I create it with the aboved code , it does not have these "=0D=0A" (new line ) characters. like below ..

BEGIN:VCALENDAR
BEGIN:VEVENT
DTSTART:20060125T151200Z
DTEND:20060208T151200Z
LOCATION:1
DESCRIPTION;ENCODING=QUOTED-PRINTABLE:1aaaa
aaaa
SUMMARY:1
PRIORITY:3
END:VEVENT
END:VCALENDAR

what am I missing ? how do I create this properly, someone point me into the right direction please :P
thanks

I had the same question, and with the exampple you wrote I could see the answer, and yes, you need to write '=0D=0A' at the end of your lines:

objStringWriter.WriteLine("DESCRIPTION;ENCODING=QUOTED-PRINTABLE:Some text=0D=0AMore Text=0D=0AA new line=0D=0ALast Line=0D=0A");

and this will return:
Some text
More Text
A new line
Last Line<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

Hope this information helps.
