Learning ATL/WTL/COM/DCOM

Hello All,

My boss wants me to learn more about ATL/WTL/etc... programming, as we are trying to replace the bulky, slow MFC libraries.
What are your opinions on these libs?
I think (so far) that WTL is pretty neat, fast, and easy, although not officially supported by MS.
I am looking for any tutorials on this subject that I can find, as I have to teach some of my coworkers on the subject in the next month(s).
Any help/opinions appreciated.
Oh ya, we use msvc++ 6, others are not an option.:)

There's quite alot of stuff here.

Thanks, I'll have a look there.
