passing function problem

ok i build the client and i get the following errors

C:\Documents and Settings\chris285\Desktop\tutorials\Sending and Receiving\Client\main.cpp(17) : error C2660: 'connecttoserver' : function does not take 0 parameters
C:\Documents and Settings\chris285\Desktop\tutorials\Sending and Receiving\Client\main.cpp(21) : error C2660: 'disconnectfromserver' : function does not take 0 parameters
Error executing cl.exe.

on these lines of code in the main.cpp file

Code:

---

#include "connecting.h"
#include <iostream>
#include "mesagesend.h"

#include <winsock2.h>

#include <stdio.h>

using namespace std;

int main()
{
        connecting client;

        mesagesend chat;

        client.connecttoserver();

        chat.sendmessage();

        client.disconnectfromserver();
        return 0;
}

---

how would this be done?

would it be stated in the function? e.g. port == kinda thing?

trouble is the ip address of the pc is going to be differnt on each pc as it will be used on my uni network, so really i need a way for the program to find the computers ip address and what not

ok solved 1 problem, in the main i changed the line to

Code:

---

client.disconnectfromserver(chat.mysocket);

---

still got the error on the connecttoserverfunction though

Uh, stab in the dark, but maybe the connecttoserver function doesn't take zero parameters?

You have all the code right in front of you. How about not double-posting?

Code:

---

int connecting::connecttoserver(unsigned short port, const char *servername)
{
        int error;

        WSAData wsaData;        // the winsock data structure

       
        if ((error = WSAStartup(MAKEWORD(2, 2), &wsaData)) == SOCKET_ERROR) {
                cout << "Winsock Start Up Failed!" << endl;                                                        // startup winsock
                return -1;
        }

       
        int mySocket = socket(AF_INET, SOCK_STREAM, 0);                // create my socket

       
        if (mySocket == SOCKET_ERROR) {
                cout << "Error Opening Socket!" << endl;                        // make sure nothing bad happened
                return -1;
        }

        struct hostent *host_entry;


        if ((host_entry = gethostbyname(servername)) == NULL) {                                // setup the host entry
                cout << "Could not find host!" << endl;
        }

        struct sockaddr_in server;

       
        server.sin_family = AF_INET;
        server.sin_port = htons(port);                                                                        // fill in the server socket info
        server.sin_addr.s_addr = *(unsigned long*) host_entry->h_addr;

       
        if (connect(mySocket, (sockaddr*)&server, sizeof(server)) == SOCKET_ERROR) {                // connect to the server
                cout<< "Error connecting to server!" << endl;
        }

        cout << "Connection Established" << endl;

        return mySocket;
}

thats the function, i just can't see where i am going wrong. prob been staring at the code too long :confused:

Go and read up on functions, argument to functions and functions in classes!
