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

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???
