question - using classes from a DLL

[Jake D]

I understand how to load a DLL in C++ and use functions from it,
however I have a DLL which I did not create which has some classes in
it. I can't seem to find out how to use the classes to make an object
and then to be able to use methods of the object

That's what documentation is for. Read it.
Your question has nothing to do with the C++ language
(the only topic here).

Thanks for being rude but you obviously didnt understand the question.
Its not that I dont know how to use the *specific* classes of that
DLL, I dont know how to use a class from ANY DLL. The documentation
from the DLL only has examples for VB so that doesn't help at all.

Posting off-topic messages is rude, so you were rude first.

Standard C++ (the topic of this group) does not provide any way to
create or use DLLs. Please read the welcome message (as we request all
new posters to do *before* they post - had you looked a few days back in
the posting history, you would have found it under the subject
"===Welcome to comp.lang.c++! Read this first." Reading such messages
before posting is standard Usenet etiquette.):

OTOH there is an active proposal on the table at the C++ comittee (from Pete
becker IIRC) to add just that. I am not saying that it makes it topical
here. Just FYI.

That's interesting. I'm not totally sure what to think of it, but I
think it would be a nice addition. On the other hand... the language is
overwhelming for me as it is, and the idea of more additions, ANY
additions, frightens me a bit. But I know they are coming, regardless.

They are coming into a Technical Report Draft if they get accepted. After
that the TR has to be accepted. And then it is still a long way from
getting it actually into a new language standard.

Also note, that these additions are mostly non-intrusive. Meaning: if you
do not use them, you do not need to know about them.
