An "interface" is a list of function pointers. In C and C++ the layout of
an interface is typically described in a header file.

Yes. It means Sun is too stupid to even know what a "GUID" is.

No.

Yes.

For a minute there, I was honestly worried you might say "What?"

Avoid that crap. That's exactly why there's so much crap-ware out there.
People release crap, and then (even worse) others battle to make it work for
them in a crappy way instead of just saying "Forget it, this is crap."
(Can you tell I'm sick of crapware today?)

This was my conclusion also.
Surely the correct behaviour would be to register a single interface and
give it a "do you support this API version?" method...

Heh. I lost count of how many Office-related DLLs are in there. There's,
like, A LOT!

Well, it's not as if I've memorised every scene and every line of dialog
from The Matrix or anything like that...

Did anybody else notice that, unlike every other GUIDE on the planet,
these ones have a *pattern* in them?
CAFE-EFAC? Oh, that's cute. ABCDEF-FEDCBA? Come on, guys...

Not necessarily. But I'm pretty sure you're not going to get good "globally
unique identifiers" by manually including english words in them.

That's because you can program Office from outside of Office.
