first winsock...

why do i get so much junk when i try to receive what the smtp server is sending? try it the smtp is valid :p

Code:

---

#include <winsock.h>
#include <iostream.h>

int SendData(char sendBuf[],SOCKET theSocket,int nRet);
int RecvData(char recvBuf[],SOCKET theSocket,int nRet);

int main(int argc, char** argv)
{
        WORD version = MAKEWORD(1,1);
        WSADATA wsaData;
        int nRet;
        char hostip[50]="smtp.wwexp.com";       
       
        //Start up Winsock as before
        WSAStartup(version, &wsaData);       
        //Store information about the server       
   
        LPHOSTENT lpHostEntry;
    lpHostEntry = gethostbyname(hostip);//Specifying server by its name
    if (lpHostEntry == NULL) {
                cout<<"Error at gethostbyname()"<<endl;
                WSACleanup();
                return (1);
    }

        //Create the socket       
        SOCKET theSocket;
        theSocket = socket(AF_INET,        //Go over TCP/IP
                          SOCK_STREAM,                //Socket type
                          IPPROTO_TCP);        //Protocol
        if (theSocket == INVALID_SOCKET)
        {
                cout<<"Error at socket()"<<endl;
                WSACleanup();
                return (1);
        }
        // Use SOCKADDR_IN to fill in address information
        SOCKADDR_IN saServer;       
        saServer.sin_family = AF_INET;
        saServer.sin_addr = *((LPIN_ADDR)*lpHostEntry->h_addr_list);
                          // ^ Address of the server being inserted into the address field
        saServer.sin_port = htons(25);//port to connect to
        // Connect to the server       
        nRet = connect(theSocket,
                      (LPSOCKADDR)&saServer,                //Server address
                      sizeof(struct sockaddr));        //Length of address structure
    if (nRet == SOCKET_ERROR) {
                cout<<"Error at connect()"<<endl;
                WSACleanup();
                return (1);
        }
        char sendBuf[256];
        char recvBuf[256];
        RecvData(recvBuf,theSocket,nRet);
        cout<<recvBuf<<endl;
        char socketcommand[100]="";
        strcat(socketcommand,"Helo ");
        strcat(socketcommand,hostip);
        strcpy(sendBuf,socketcommand);
        SendData(sendBuf,theSocket,nRet);
        RecvData(recvBuf,theSocket,nRet);
        cout<<recvBuf<<endl;
        //Successfully connected!
        closesocket(theSocket);
        //Shutdown Winsock
        WSACleanup();
        return (0);
}
int SendData(char sendBuf[],SOCKET theSocket,int nRet)
{
        nRet = send(theSocket,                //Pretend this is connected
                                sendBuf,                //Our string buffer
                                strlen(sendBuf),//Length of the data in the buffer
                                0);                                //Most often is 0, but see end of tutorial for options
        if (nRet == SOCKET_ERROR){
                cout<<"Error on send()"<<endl;
                return (1);
        }
        return (0);
}
int RecvData(char recvBuf[],SOCKET theSocket,int nRet)
{       
        nRet = recv(theSocket,                // Connected socket
                                recvBuf,                // Receive buffer
                                sizeof(recvBuf),// Size of the buffer
                                0);                                // More flags
        if (nRet == SOCKET_ERROR) {
                cout<<"Error on recv()"<<endl;
                return (1);
        }
        return (0);

i tired you method but i dstill get some kind of garbage when it is displayed.... so weird sideways charecter

Try initializing the recvBuf to 0 before you do a recv() in it:

Code:

---

memset( recvBuf, 0, 256 );

---

Also, as vVv pointed out, you are recv()ing for max of sizeof(recvBuf) bytes which basically is: sizeof(char *) i.e. 4.

Everything else looks ok. If you still get the garbage, check what exactly are you sending in the SendData() proc. Do a:

Code:

---

cout << sendBuf << endl;

---

just before doing send()

Also, in which recv() are you getting this garbage???
