linking error in "winsock2.h"
Author
i just have start learning programming winsocket using visual studio 2003
but just in the begining i had some prp
i have wrote this code:
#include "stdafx.h"
#include "winsock2.h"
using namespace std ;
void main()
{
WSADATA wsaData;
int iResult = WSAStartup( MAKEWORD(2,2), &wsaData );
if ( iResult != NO_ERROR )
printf("Error at WSAStartup()\n");
}
and it just keep telling me this error
winsocket error LNK2019: unresolved external symbol __imp__WSAStartup@8 referenced in function _main
i just think that the prp is that i have to link the winsock2.h
but the prp that i dont know how
should i download something .lib and then add a reference to my project or what
i will appreciate ur help
Hmmmm, if I recall correctly, you need to include "windows.h" before "winsock2.h". But since that's a linker error, I'm not sure if that would solve your problem.
The only thing I know is that I had problems not including windows.h.

This sounds like a question about how to properly use MSVC, rather than a question about networking or multiplayer programming. You would probably get better help from a forum dedicated to tools help...
Actually, you typically want to include <winsock2.h> before you include <windows.h> to avoid some naming conflicts. <windows.h> is typically compiled into the precompiled headers, so you should add <winsock2.h> into your "stdafx.h" file, before that includes <windows.h>.
The link error is likely because you haven't added ws2_32.lib to the list of libraries to include, in the Linker settings.

Open MSVC.
Open the online help.
Search for "adding library to project".
Because this thread now has nothing to do with network programming, I'm going to close it; please find the appropriate forum for posting questions on how to use Visual Studio (or at least try reading the manual :-)
