Problems with winsock2.h
Hello
im trying to program a client server model in C++ and wanted to do this with winsock2.h. But it doesnt seem to be able to find this in MSVC++ 6.0. Or are the functions wrong here a sample code:
pubcomm::pubcomm()
{
}
pubcomm::~pubcomm()
{
pubcomm::close();
}
void pubcomm::close(){
//cleanup pubcomm datas
shutdown(sock,SD_BOTH);
closesocket(sock);
}
char* pubcomm::IP_CLIENT="123.45
char* pubcomm::IP_SERVER="123.45
int pubcomm::PORT_CLIENT=1024;
int pubcomm::PORT_SERVER=1024;
Any suggestions?
or even a sample code that works for this problem?
All the best

both does not work....
my includes:
#include <stdlib.h>
#include <stdio.h>
#include <vector>
#include <cmath>
#include <iostream>
#include <winsock2.h>
It seems to be a linking problem... do I have to change sth on the makefile?
Thanks

your ip addresses are wrong!
you just can't use anything.
apart from that code looks ok.
send us the part you are trying to connect or bind/listen.

ok the ip adresses are certainly wrong. but thats not the problem. this cant check the compiler I think.
The pragma comment thing works. But I dont know why. WHY?

The #pragma directiva makes the linker link with the winsock2 import library - that's the trick.
