explicitly load a MFC extension DLL that exports a CObject derived class?
Is it possible to explicitly load a MFC extension DLL that exports a CObject derived class? The calling exe is an MFC app. I have no problem doing this using a .lib file linking implicitly. Can you please supply a small code sample.

That would be great! I look forward to your email.

Surfer,
What is that you can not do? Do you need to know how to load a dl explicitly or do you need to know how to export a MFC derived class in a dll? If you explain a bit more we can help you.
My 2 cents...

The main part of my question is:
I have a class
AClass : poblic CObject
{
...
}
I want to export my class from my DLL to the calling app. If I use implicit linking I know what to do. However, if I link explicit, what is the best way to import this class into my exe? I know who to use exlictt linking with functions, but how do I do it with a classes and is it safe?
Thanks

Surfer,
To export an entire class from a dll you must prefix the class with AFX_EXT_CLASS like so...
class AFX_EXT_CLASS AClass : public CObject
{
...
}
and of course your dll must be an MFC extension dll since you are subclassing CObject
