Ok I tried one test code and it worked, but when I moved the all the
classes in header file and but the export macro in cpp file it fails
with "derived class not registered or exported".

Then I moved the export macros to main.cpp right before main() and
before the saving/loading calls, and that did the trick.

So it seems export's need to be in same CPP file where the
loading/saving starts?
Or is it in same cpp where the function is?

Im using visual studio 10 express
