[Shapelib] Using Shapelib in VC++ .NET

First I would like to thank you for offering this library to the public, and
it is greatly appreciated.
I am new to shapelib and ArcView itself. I am developing a VC++ .NET
windows application for converting a file into an ArcView shapefile. I am
glad to have come across this library, but I am having a few problems.
I have #include "shapelib.h", "shpopen.c", and "dbfopen.c" to my project
(first off, I dont know if that is the correct way to add them). Since
dbfopen.c and dbfopen.c have some of the same functions, I am getting
redifinition errors. I have actually successfully created the .shp and .shx
files before I added the "dbfopen.c" file to my project. Basically, I need
to know how to properly interface the shapelib library with my project.
Is it possible for ArcView to automatically determine a projection (I
believe that is what they are called in ArcView) based on decimal degree
coordinates (or UTM) and to make a zoom to best fit a point shapefile?
Would it be possible to code that functionality? Also, is there a way to
create layers outside of ArcView?
Thanks in advance,
