anyone know what ical and outlook are programmed in?

Hey all, I was wondering if anyone could tell me what iCal and Outlook are programmed in offhand. I have an ambitious but probably not so thought out plan on builing some mods for phpwebsite based off of phprojekt, squirrelmail, myphpcalendar, and was thinking I would write my own address book, but will probably use the one built into projekt. This info will help me greatly, because I'll write files that will pass the address book and schedule info from Outlook, and just the schedule infor from iCal, onto my system (if it is even possible...) Thanks, Kevin Myrick PS- Where would I look to find the PEAR libs documentation on what each function, in each file, does. I plan on printing this out so I can take a clos e look into designing my system... PEAR is used in the new version of phpwebsite (currently 0.9.0RC4) and wanted to use this common function system to do the rest of the design for me. ===== Kevin Myrick /etc/KevX45 http://www.ultimatealchemy.com webmaster@ultimatealchemy.com "Screw you guys, I'm going home."-Eric Cartman, South Park Ultimatealchemy Dotcom! __________________________________________________ Do you Yahoo!?
