Calling an XLL from (unmanaged) C++

Question

Hi,

I have an XLL Excel addin and now another team wants to use the same functionality in their project (unmanaged C++). Is there a way to interface with this XLL directly from C++?

Answer 1

Is you XLL un managed or unmanaged code?

As far as I know, an unmanaged C++ XLL file is in fact a DLL that exports specific methods called by Excel.

If your XLL has a .def file, maybe you could add method that would be called by the other team.
