Importing a VC++ class into a C# program

[Rookie]

Hi

I had a couple of questions:

1.)I am trying to invoke member functions of a class which is coded in
VC++ from a UI that is coded in C#. Firstly, if I am not mistaken I
think this can be done only if the exposed classes are managed. I am
totally new to this. So can someone give some pointers or maybe some
URLs to links on how this can be done - that is how to firstly be
able to export the classes and also how to make them managed/write
managed wrappers for the class.

2.)Once the VC++ coding is done, how do I invoke the member functions?
How do I instantiate an object of the VC++ classes in the C# code. It
would be great if someone could post some links to good articles that
deal with this.

Thank you.

1) You can't directly expose a native interface to managed code, your only
option is to use "Managed Extentions C++" or VS2005's C++/CLI to wrap a
managed reference class around your native class and populate it with stub
methods that invoke the associated native methods.
2) Invoking the methods is done by simply invoking the stubs.
