Yes, you can do it. I've been through the same process. Here is what I recommend...

VS2002 is the oldest version of .NET - first update your C++ code to something more recent (ie. VS2012/VS2012). When upgrading, you will probably find that the newer compiler versions find more coding errors and indiscretions. Fix all of these and make sure that everything works as expected. While you are changing/upgrading your source, I also recommend /W4 warning level, which will enhance the compiler help. I went through this process on a 10 million line code base and was astounded at the garbage in the source which somehow magically worked. This is your best opportunity to fix these types of errors.

After you have completed this part of the process (and not before!), change your project executable to enable C++/CLI. Read up on mixed mode execution. You will now be able to create new managed DLLs that you can call from the executable.

What I have described is how to call managed code from project.exe. Managed code can call unmanaged DLLs via several mechanisms (see "P/Invoke", ...). Calling managed code from unmanaged DLLs is much more complicated. You will also be limited to MFC UI features. Different Visual Studio versions give you different capabilities.
