1) Only in the base class the virtual specifier is needed. So you might not see that they are virtual but a lot of MFCs functionality is virtual. Some you can find in the ClassView: right click on a class and you get the option "add virtual function". Have a look at them. Another class of functions are message handlers which act a bit like virtual functions as well.

2) This strongly depends on what you want to achieve. For showing some numbers I don't see a big advantage in going to a doc/view architecture. This changes if you want an application to handle a special type of files. Each file is than seen as a document which can be viewed inside the applicatoion.
