Juno is definitely of more value if you're trying to access
standard Windows COM objects, that way you don't have to write
the interface definitions yourself.
You'd mentioned that you got it work with a hack and there should
be a better way, Juno might be that better way.
It looks to me like your extern(C++) is needed because you're
trying to shove the pointer from coCreateInstance into a D class.
With COM you don't work with concrete classes, only interfaces.
Code below is not tested and only from limited knowledge.
IMYCASIO cASIO : IUnknown
{
void func1(char *name);
void func2(int);
}
//...
IMYCASIO obj;
CoCreateInstance(..., cast(void**) &obj);
obj.func1("me");
The only other thing I can think is, if you are obtaining an
object that defines static methods, those aren't supported by
COM. COM only works on virtual functions and you're probably just
hacking memory address space to get at those functions.
