Mixing VC++/MFC app with .NET/Activex components

[Kunal]

I have an application that was fully developed in VC++ 6.0 using MFC.
I have to enhance the application in 2 ways:
1. Add some graphics stuff (draw graphs), and
2. Perform serial port communications

Unfortunately, for 1, I've been given an ActiveX component that was
developed using .NET.

My questions are:
1. Is there some way of directly "using" the .NET Activex component in
VC++ 6.0? I can then write the serial port comm module in VC++ 6.0
(since its far more difficult to write seril I/O in .NET), or
2. Should I port my VC++ application to .NET, directly use the Activex
component and write a serial I/O module in .NET, or
3. Is there another, more elegant solution?
Thanks in advance
