问题
I am creating a simple application that will allow users to download .ICS files, and import them into their chosen calendar application/site.
I am happy with the creation process, but have a question regarding opening them in outlook. (will be developed in C#, ASP.NET)
When I open one, it adds a new calendar, and doesn't add the events to the existing calendar.
Is it possible to open, and add to the existing calendar? Example from a generate ICS file below (test data obviously)
BEGIN:VCALENDAR
VERSION:2.0
PRODID:-//hacksw/handcal//NONSGML v1.0//EN
BEGIN:VEVENT
DTSTART:20100623T1101100Z
DTEND:20100623T1401400Z
SUMMARY: England v Slovenia
LOCATION: Some where in South Africa
END:VEVENT
BEGIN:VEVENT
DTSTART:20100624T1101100Z
DTEND:20100624T1401400Z
SUMMARY: England v Slovenia again (replay)
LOCATION: Some where in South Africa
END:VEVENT
END:VCALENDAR

Yes, but that has to happen by the user and not the ICS file; I remember dealing with this before too, if you want to import into an existing calendar, there is an import feature in the menu...
Sorry for the vagueness, I dealt with that long ago and cannot remember the exact steps... I did find the answer in the help I believe, but essentially you can import them in, but if you open up the ICS directly, it creates a new calendar.
Also, it isn't smart enough to delete the old ones, so if you import more than once, you will have duplicates.
HTH.

To add events to an existing calendar, first you have to save .ics file and then import it, choosing Import instead of New while importing.
