And i don't know what this errors mean.
I am learning from Examples:

I am using Visual Studio 2010, but i have this errors in all compilers/writers (Code::Blocks,Dev cpp etc.)

The linker can't find those functions. Have you added the (correct) library path to your lib directories?

You need to link with ws2_32.lib

I added #pragma comment(lib,"Ws2_32.lib") to my code and it's works, thanks :)
