hi all,I want to send a bitmap file that was witten in VC++ by using socket programming.Firstly I can send message form client to server.But how can I send the file.The code is below Thanks

Server part:

#include <iostream>

#include <winsock.h>

#include <windows.h>

#include <vector>

using namespace std;

#pragma comment(lib, "wsock32.lib")

void socketError(char*);

char * readline(SOCKET *s);

int main()

{

WORD sockVersion;

WSADATA wsaData;

int rVal;

sockVersion = MAKEWORD(1,1);

//start dll

WSAStartup(sockVersion, &wsaData);

//create socket

SOCKET s = socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);

if(s ==-1)

{

cout<<"eror creating socket\n";

WSACleanup();

return(0);

}

//fill in sockaddr_in struct

SOCKADDR_IN sin;

sin.sin_family = PF_INET;

sin.sin_port = htons(8888);

sin.sin_addr.s_addr = INADDR_ANY;

//bind the socket

rVal = bind(s, (LPSOCKADDR)&sin, sizeof(sin));

if(rVal ==-1)

{

cout<< "bind failed\n";

WSACleanup();

return(0);

}

//get socket to listen

rVal = listen(s, 2);

if(rVal ==-1)

{

cout<<"listen failed\n";

WSACleanup();

return(0);

}

//wait for a client

SOCKET client;

cout << "waiting for newclient" << endl;

client = accept(s, NULL, NULL);

cout << "newclient found" << endl;

if(client == INVALID_SOCKET)

{

cout<<"Failed accept()";

WSACleanup();

return (0);

}

readline(&client);

//close process

closesocket(client);

closesocket(s);

WSACleanup();

cout << "closing down"<< endl;

return 0;

};

char * readline(SOCKET *client)

{

vector<char> theVector;

char buffer;

int rVal;

while(true)

{

rVal = recv(*(client), &buffer, 1, 0);

if(rVal ==-1)

{

int errorVal = WSAGetLastError();

if(errorVal == WSAENOTCONN)

{

cout<<"Socket not connected!";

}

cout<<"Failed recv()";

WSACleanup();

}

if(buffer == '\n')

{

char *data = new char[theVector.size() + 1];

memset(data, 0, theVector.size()+1);

for(int i=0; i<theVector.size(); i+=1)

{

data = theVector;

}

cout << data << endl;

return data;

}

else

{

theVector.push_back(buffer);

}

}

}

void socketError(char* str)

{

MessageBox(NULL, str, "SERVER SOCKET ERROR", MB_OK);

};
