Well i don't see where you added the methods or the menu command. *

Man I've got to tell you that this code is a horrible example to learn
from! The styling abominations and obfuscation is just simply
atrocious! It seems the author was trying to confuse everyone
including himself! So i modified it just a bit.
I added the OnPrint method however i am leaving it up to you to build
the Print menu and do the binding. I put some comments where you need
to add the print menu. Just look at how the other menus are created
and you'll figure it out ;)
Let us know if you need more help.
