(Outlook) Creating custom "message rules" for Outlook Express

[montanasoft.com]

Hi: I'm a fair-to-middling VB6 programmer (the more I learn, the more I realize how much I don't know). I haven't done any VBA before, but I'm comfortable with VB.

I'd like to create custom message rules for Outlook & Outlook Express. For Example, I'd like to forward all messages in Chinese to a separate folder.

Here are some newbie-type questions:

1). How can you tie into the message before it's added to the Outlook inbox (to filter it)?
2). What type of code would be necessary to examine the CharacterSet of the message? Would you just parse the message, or is there a more direct way?

Thanks!!
