159 Views

Hi All,

I am working on a LSO project. We have a requirement to send the schedules as an .ICS attachment to outlook, I am able to send the .ICS attachment successfully if the schedule is for one day as in the example

CASE1:

Course Name BEGDA ENDDA BEGUZ ENDUZ

Environment Safety 20101226 20101226 080000 090000

This is how my caleander file looks like for the above example:

BEGIN:VCALENDAR
PRODID:-//Microsoft Corporation//Outlook 12.0 MIMEDIR//EN
VERSION:2.0
METHOD:REQUEST
X-MS-OLK-FORCEINSPECTOROPEN:TRUE
BEGIN:VEVENT
ATTENDEE;CN="Name";OLE=REQ-PARTICIPANT;RSVP=TRUE:mailto:xxxxx@zzz

DESCRIPTION: Environment Safety Training\n
DTEND:20101217T203000Z

X-MS-OLK-AUTOFILLLOCATION:FALSE
X-MS-OLK-AUTOSTARTCHECK:FALSE
X-MS-OLK-CONFTYPE:0
END:VEVENT
END:VCALENDAR

CASE2: ( Recurring event )

Course Name BEGDA ENDDA BEGUZ ENDUZ

Environment Safety 20101226 20101226 080000 090000

Environment Safety 20101227 20101227 080000 090000

CASE3: ( Recurring event with irregular schedules)

Course Name BEGDA ENDDA BEGUZ ENDUZ

Environment Safety 20101226 20101226 080000 090000

Environment Safety 20101227 20101227 080000 120000

can you please let me know how to build the ICS file for the above cases.

your comments are highly appreciated.

Thanks,

Krishna
