Using Visual C++ 2010 Express to access Postgres

Hi,

I am trying to access from Visual C++ 2010 Express a Postgres database. I have both on my machine but the SQL calls do not work at all. I have searched many sites. I think that this version of Express does not have any default database connections like the non-express version (especially Visual C++ 2008).
The only thing I could find was the following link and I have following the modifications to the Project Properties area of Visual C++ Express.

askby. com/cpp/c-postgresql-example/

When I try to run the C++ code in that website I get errors indicating that it cannot find the functions.
Do you have any ideas of what I am doing wrong? Would it be better for me to use something other than Visual C++ Express 2010 to connect to a postgres db? One of the other Express versions? The regular (non-express) Visual C++?

Thanks,
Jim
