Hi - I'm trying to find out if this can be done by building the code yourself or if a 3rd party add in has to be involved. What I am trying do is display a link on a web page that says 'Add this event to your calendar'. When they click it will pass in the information and add it to their calendar. I have seen this done before on certain pages and when I click the link it has me download or run a file with a .vcs extension (vCalendar File Type). If I run this it adds it to my outlook calendar. It is able to set the title of the event, the time and even a reminder. So I'm trying to find out if I can do this sort of thing myself or if this is something I need to purchase to produce this .vcs file for me. Thanks for any help provided.
