For an overview of
Data Access from VC++, I think that the MSDN page is pretty good. In order to get a higher level introduction, you probably want to pick up one of the basic books or courses. There are some good references for
core MFC development at MSDN too.
Assuming that you need to dynamically build a connection string, I'd suggest that you check the
dBase. That page is specifically for dBase connections, with links to related (more general) pages.
If you can use a static connection, build a system DSN
