Read the documentation for the dlls. The header files normally come with experience - generally you get a compiler warning if you try to use std::strings with declaring #include <string> for example.

MSDN will normally tell you what header files and libraries are need for a given function. goto www.microsoft.com and search for the function name.

Hey it depends on what task you are given, you need also to make use of the help in your c++ type header files in the serch and you will have a list of header files.
