You should ask one question per post, so that if it generates discussion, it doesn't turn into a muddle.

1 - The System.IO.File namespace contains static methods to read and write files, they are also available through My.FileSystem, or something like that ( not sure on that one ). There is no built in support for encrypting files.
2 - www.codeproject.com may have sample code on a chat program. Otherwise, that's too big a question for a forum post. You'd need to do it, and ask more specific questions as you get stuck.
3 - DateTime.Now gets you the current date and time. You can set a timer to update a label with the value of this property if you want to display it
4 - yes. There are a number of ways - google 'internationalisation'
5 - How to add a calendar to what There is a calendar control, which lets you pick dates. If you want an outlook style calendar, you'll need to write the code to create it, and if you don't want a database, it will need to be very small ( to be managable ), and save the information to a file to disk, probably using XML.

K, If I get stuck I'll post it then and if I got something new I'll make a new post.
Tnx for the info already.

Great - the other thing is that these forums get searched by MSDN help, so keeping one subject per thread helps others by improving search.
