is it possible to export (and, above all, import afterwards) an unmanaged class from a managed dll (compiled with the /clr switch. it would in fact probably result in a mixed mode dll)? it seems that member methods of any exported unmanaged class are compiled as static and global if the /clr switch is on. why? how to import such classes in antoher project? is there a workaround?
thanks...

__declspec(dlle xport) and __declspec(dlli mport) or whatever other mechanism
you are already using in the situation where you are not compiling with
/clr.

Thanks Ronald.
Still, it does not respond completely to my questions: "how?" & "i
there a workaround?".
There might be one: the exported unmanaged class should inheri
from an unmanaged pure virtual class (technically an interface), b
created by a managed class from the same (managed, compiled with /clr
library, and presented to the outside world as the mentioned unmanage
interface. It is maybe a little bit "heavy", but I haven't found an
other way.
Thanks again.

I think I am still misunderstandin g what you are trying to do. To export a
class (i.e. the definition of a class since that is the only thing you can
"export") is completely independent from whether you compile the DLL with
the /clr switch for all compilands, for no compilands or for a subset of all
compilands.
What you are referring to now seems to have something to do with an instance
of this class.
If you can provide a few lines of sample code, plus an illustration of what
broke in your scenario by virtue of specifying the /clr switch should make
sure I understand fully what you are trying to do.
Thanks!

I'm attempting to put a C# front end on my unmanaged C++ ray tracer code.
It's still in experimental stage, as I have never done anything with

Currently, I have an unmanaged dll, a managed C++ wrapper dll and a C# dll.
I have managed to get enough exported from the unmanaged code to get a
vaguely correct picture on the screen, however there is some odd behaviour.

Hi,
I have a MC++dll, whose functions i want to use in unmanaged c++. I
read that one of the ways to use the managed functions in unmanaged
world is by exposing the managed api as flat api.
I tried that and with simple data types it worked. But now i need to
export a function which needs to take a gc struct as parameter, and
then fill some values in it, and then the unmanaged c++ will use that
info.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
