Hi
I am using visual studio C++ 6, with SDK, my mysql database is 4.1.18, i
downloaded mysql++ 1.7.1 as this is the compatiable version for vc++6.
the example program compiles and runs. when i go to make my own project i use
the wizard and create a basic dialog MFC app. at the top of the main cpp file i
add #include <mysql++> and then in the program call Connection
con("login","localhost","root","abc");
in the mysql++ download there is many lib and include folders, i have copyied
the contents of these in the the vc++6 include and lib folders.
when come to compile i get many errors as seen below. please help
