Export class from c ++ dll?

How to open a class from dll?

An application importing a dll must be able to create class objects, and it must also be able to call member functions of the class.

Is it compatible with how to expose type C functions with __declspec(dllexport)?

And also when I built the dll (which contains only the class definition in the header file and its definition of member functions in the cpp file), the corresponding lib file is not created.

Yes. And __declspec can be applied to the class.

the corresponding lib file is not created

IIRC is the default, but you can override the default linker options.

Googling for the dllexport class led to this page from MSDN as the first result.

The page seems to show that only __declspec(dllexport)is all you need to do.
