These are from not having the right libraries for the linker to resolve
the symbols from. Not a language problem. Off-topic here.

Try for the next half-a-year to ask _all_ questions you have in the VC++
newsgroup: microsoft.public.vc.language. You'll learn a great deal about
your IDE and the particulars of the compiler, and when you're ready to
ask _language_ questions, come back.
