you need to make the .Net compatible with unmanaged code(eg, activex). Use tblexp utility for that, it creates a wraper for you.

examples here:

syntax for tblexp here

One way that I have used is
Make a Bridge dll (a managed C++ DLL), which load the .Net lib in AppDomain.
Now for calling any .net lib function from your C++ module,
From C++ make a call to Bridge DLL function, which eventually makes the call to .net functions in the lib loaded in its AppDomain.

C++ Module ==> Bridge DLL ==> .net Lib
