>I noticed [IntelliSense in VC++ 6.0] on Friday for function calls, but... it only shows you the type of the argument, which while useful isn't as useful as seeing type and argument name. And it doesn't do member function arguments.

Hmmm. I think you're talking about the tooltip-like capability, that shows the type of _any_ identifier when you hover the cursor over it. That should kill Hungarian notation dead! :)

VC++ also has the dropdown property/method list and function argument help that VB has had, but it's only for Microsoft library functions, not your own (I'm pretty sure).
