Try this:
#pragma comment(lib,"Ws2_32.lib")
Add it to your file.

If you are using a MSVC-compatible compiler(Borland, Intel ...), use
"#pragma comment("ws2_32.lib")".
If you are using GCC(MinGW/Cygwin) or a compiler that doesnt support
auto-linking, you need to fix the linker command. For example, in case
of GCC, you have to add "-lws2_32" to the linker command.

"-lws2_32" to the linker command. can you please tell me where and how
I should add this "-lws2_32" ?

Add "Ws2_32.lib" without quotes to Linker->input in your visual studio project.
