Programming a VPN connection

[Benjamin Post]

I'm interning for a small engineering firm and found that I might be a little
over my head, in terms of using VC++ and programming for Windows. I have
already developed a method for transferring files across a network, via phone
lines that are connected through RAS. Now, the company wants me to create
a program that allows the data transfers to occur over the internet using
VPN technology. My problem is that I know very little about VC++ (learning
more everyday though) and programming Windows. I would appreciate if someone
could point me in the right direction, via reference material or personal
knowledge.Thanks,Benjamin

If you know how to use MFC in VC++, then you can use the CSocket class in
conjunction with the CSocketFile and CArchive classes to easily transfer
any type of data over the Internet, including files.

So, using VPN is not necessary as far as the data transfer is concerned?
What about security issues, such as authenticity and data integrity? The
data transferred is not top-secret, but directly relates to customer billing.

Also, what if the data transfer requires network authentication? How is
that then handled?

Thanks very much,
Benjamin
