What is the difference between iCalendar and CalDav?

What is the difference between iCalendar and CalDav?

I'm quite confused between the two.

How do I create an iCal-type .ics file that can be downloaded by other users?

I want to create an iCal Calendar that can be downloaded from my website to the users Calendar program or imported to Google Calendar. What I want to know is if I do a direct Export from iCal on Mac OS X is that the file that I upload to my server? Any catches or caveats I should be aware of? Or is there a better way?

Is there a javascript calendar that takes an ical link as input to display events?

I am looking for a javascript based calendar that will allow me to specify a remote ical file to use as the source for the events.

I know google will allow you to import the ical then view the calendar via js or iframe, but I need to keep this agnostic to individual user accounts of any time.

Any suggestions?

Thanks

ICalendar and event updates not working in Outlook

I'm generating ICalendar (.ics) files.

Using the UID and SEQUENCE fields I can update existing events in Google Calendar and in Windows Calendar BUT NOT in MS Outlook 2007 - it just creates a second event

How do I get them to work for Outlook ?

Thanks

Should I store dates or recurrence rules in my database when building a calendar app?

I am building a calendar website (ASP.NET MVC) application (think simple version of outlook) and i want to start supporting calendar events that are recurring (monthly, yearly, etc)

right now I am storing actual dates in my but I wanted to figure out if, with recurrence, does it make sense to continue to store dates (with some obvious cutoff), or should I store the recurrence options and generate the dates on the fly.

It got me thinking how outlook, google mail, etc does this or any other service that supports recurring calendar items.

Are there any suggestions on this?

Importing ics file to an Outlook.AppointmentItem

I have an Outlook 2007 add-in that is trying to import ics files into Outlook.AppointmentItem objects so that I can read attributes about certain appointments. Currently I am not able to read the ics back into memory. Any suggestions on what I am doing wrong.

Outlook.Application app = new Outlook.Application();
var item = app.Session.OpenSharedItem("C:\\meeting.ics") as Outlook.AppointmentItem;
string meetingBody = item.Body; //<--*my item is null*

Thanks

I want HTML link to .ics file to open in calendar app when clicked, currently opens file as plain text. Suggestions?

I am linking to an .ics file exported from Apple iCal in an HTML web page.

<a rel='nofollow' href="calendar.ics">

This link will open the calendar.ics file as plain text in my browser (Chrome). I want automatic opening in Outlook or iCal or other calendar apps. What can I add to the link tag in order to produce the desired behavior? What about modifying the HTTP headers on .ics files?

Any suggestions are appreciated!

DDay iCal - adding an Attendee

How does one add required/optional attendees + organizer(s) to an iCal event?

I'm using the excellent DDay library, and would love to be able to also add a CN, but haven't found any examples in the documentation, the downloaded examples or elsewhere.

Thanks!

How can I use PHP to dynamically publish an ical file to be read by Google Calendar?

Any Google search on PHP ical just brings up phpicalendar and how to parse or read IN ical files. I just want to write a PHP file that pulls events from my database and writes them out in ical format.

My problem is I can't find anywhere that will answer two questions:

1. What is the exact ical format, including headers, file format, footers, etc.? In other words, what does the file have to have, exactly, in order to be properly read in by Google Calendar, etc.?
2. If I build this file using a .php extension, how do I publish it as ical? Do I have to write to a new .ics file? Or will Google Calendar etc. read a .php file as ical so long as the contents are in the correct format? (Much like a style.css.php file will be read as a CSS file if the contents are actually CSS, etc.)

Any help you all can give or point me to will be greatly appreciated!!!

Creating iCal Files in c#

I'm looking for a good method of generating an iCalendar file (*.ics) in c# (asp.net). I've found a couple resources, but one thing that has been lacking is their support for quoted-printable fields - fields that have carriage returns and line feeds.

For example, if the description field isn't encoded properly, only the first line will display and possibly corrupting the rest of the information in the *.ics file.

I'm looking for existing classes that can generate *.ics files and/or a class that can generate quoted-printable fields.

Best iCalendar library for Java? [closed]

I'm looking for a library to handle iCalendar data in Java.

Open source, well-documented implementations with a good object model are preferred. iCal parsing capabilities are less important to me, but still nice to have.

Does anyone have any recommendations?

Is there a way to programmatically import ICS into Google Calendar?

I don't see any obvious way to import ICS files into Google Calendar from the API docs here:

http://code.google.com/apis/calendar/developers_guide_protocol.html

And I'd greatly prefer not to have to parse them myself just to send the appointments into GCal. I'm looking for a programmatic solution, not something like import plugins for Thunderbird, Outlook, etc. Third party APIs to do the ICS parsing are acceptable, in any language. Any ideas?

HTML in iCal attachment

Can an iCal attachment contain HTML in the description property? If so, what are the restrictions?
