Tools-->Options-->Controls lists lots of ActiveX controls available to me.

However, I can't find out how to learn what any of these actually do (can be used for). I picked a few names shown there and looked for them (Index) in MSDN (April 2002) but they simply aren't in the index.

Where does one learn:
1) What they look like;
2) How they can be used and what restrictions they have?

thanks
