VC SOCKET 文件传输程序问题

能不能帮我把下边这3个程序补充头文件等，可以在VC中运行的程序。。
还有1这个程序 在哪里定义。。
1.SOCKET_STREAM_FILE_INFO格式:
typedef struct _SOCKET_STREAM_FILE_INFO {

TCHAR szFileTitle[128]; //文件的标题名
DWORD dwFileAttributes; //文件的属性
FILETIME ftCreationTime; //文件的创建时间
FILETIME ftLastAccessTime; //文件的最后访问时间
FILETIME ftLastWriteTime; //文件的最后修改时间
DWORD nFileSizeHigh; //文件大小的高位双字
DWORD nFileSizeLow; //文件大小的低位双字
DWORD dwReserved0; //保留，为0
DWORD dwReserved1; //保留，为0

} SOCKET_STREAM_FILE_INFO, * PSOCKET_STREAM_FILE_INFO;

2.文件发送:
CFile myFile;
if(!myFile.Open(fileneme, CFile::modeRead | CFile::typeBinary))
{
AfxMessageBox("文件不存在!",MB_OK|MB_ICONERROR);
return;
}
CSocket sockSrvr;
sockSrvr.Create(800);

sockSrvr.Listen();
CSocket sockRecv;
sockSrvr.Accept(sockRecv);

SOCKET_STREAM_FILE_INFO StreamFileInfo;
WIN32_FIND_DATA FindFileData;

FindClose(FindFirstFile(filename，FindFileData));
memset(&StreamFileInfo,0,sizeof(SOCKET_STREAM_FILE_INFO));
strcpy(StreamFileInfo.szFileTitle,myFile.GetFileTitle());

StreamFileInfo.dwFileAttributes = FindFileData.dwFileAttributes;
StreamFileInfo.ftCreationTime = FindFileData.ftCreationTime;
StreamFileInfo.ftLastAccessTime = FindFileData.ftLastAccessTime;
StreamFileInfo.ftLastWriteTime = FindFileData.ftLastWriteTime;
StreamFileInfo.nFileSizeHigh = FindFileData.nFileSizeHigh;
StreamFileInfo.nFileSizeLow = FindFileData.nFileSizeLow;

sockRecv.Send(&StreamFileInfo,sizeof(SOCKET_STREAM_FILE_INFO));

UINT dwRead=0;
while(dwRead
{
byte* data = new byte[1024];
UINT dw=myFile.Read(data, 1024);
sockRecv.Send(data, dw);
dwRead+=dw;
}
myFile.Close();
sockRecv.Close();
AfxMessageBox("发送完毕！");

3. 接受文件

CSocket sockClient;
sockClient.Create();
if(!sockClient.Connect((LPCTSTR)szIP, 800))
{
AfxMessageBox("连接到对方机器失败!");
return;
}
SOCKET_STREAM_FILE_INFO StreamFileInfo;
sockClient.Receive(&StreamFileInfo,sizeof(SOCKET_STREAM_FILE_INFO));
CFile destFile(StreamFileInfo.szFileTitle, CFile::modeCreate | CFile::modeWrite | CFile::typeBinary);

UINT dwRead = 0;
while(dwRead
{
byte* data = new byte[1024];
memset(data,0,1024);

UINT dw=sockClient.Receive(data, 1024);
destFile.Write(data, dw);

dwRead+=dw;
}

SetFileTime((HANDLE)destFile.m_hFile,&StreamFileInfo.ftCreationTime,
&StreamFileInfo.ftLastAccessTime,&StreamFileInfo.ftLastWriteTime);
destFile.Close();
SetFileAttributes(StreamFileInfo.szFileTitle,StreamFileInfo.dwFileAttributes);
sockClient.Close();
AfxMessageBox("接收完毕！");

Answer 1

用VC6.0建立两个WIndows32 Console Application程序，并且选择一个支持MFC的程序，第一个程序中输入：
// server.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "server.h"
#include<afxsock.h>
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

/////////////////////////////////////////////////////////////////////////////
// The one and only application object

CWinApp theApp;

using namespace std;

typedef struct _SOCKET_STREAM_FILE_INFO {

TCHAR szFileTitle[128]; //文件的标题名
DWORD dwFileAttributes; //文件的属性
FILETIME ftCreationTime; //文件的创建时间
FILETIME ftLastAccessTime; //文件的最后访问时间
FILETIME ftLastWriteTime; //文件的最后修改时间
DWORD nFileSizeHigh; //文件大小的高位双字
DWORD nFileSizeLow; //文件大小的低位双字
DWORD dwReserved0; //保留，为0
DWORD dwReserved1; //保留，为0

} SOCKET_STREAM_FILE_INFO, * PSOCKET_STREAM_FILE_INFO;

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;

// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
cerr << _T("Fatal Error: MFC initialization failed") << endl;
nRetCode = 1;
}
else
{
// TODO: code your application's behavior here.
CString strHello;
strHello.LoadString(IDS_HELLO);
cout << (LPCTSTR)strHello << endl;
}

CSocket sockClient;
sockClient.Create();
if(!sockClient.Connect("127.0.0.1", 800))
{
AfxMessageBox("连接到对方机器失败!");
return 0;
}
SOCKET_STREAM_FILE_INFO StreamFileInfo;
sockClient.Receive(&StreamFileInfo,sizeof(SOCKET_STREAM_FILE_INFO));
CFile destFile(StreamFileInfo.szFileTitle, CFile::modeCreate | CFile::modeWrite | CFile::typeBinary);

UINT dwRead = 0;
while(dwRead)
{
byte* data = new byte[1024];
memset(data,0,1024);

UINT dw=sockClient.Receive(data, 1024);
destFile.Write(data, dw);

dwRead+=dw;
}

SetFileTime((HANDLE)destFile.m_hFile,&StreamFileInfo.ftCreationTime,
&StreamFileInfo.ftLastAccessTime,&StreamFileInfo.ftLastWriteTime);
destFile.Close();
SetFileAttributes(StreamFileInfo.szFileTitle,StreamFileInfo.dwFileAttributes);
sockClient.Close();
AfxMessageBox("接收完毕！");

return nRetCode;
}

另外一个程序输入：
// client.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "client.h"
#include <afxsock.h>
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif

/////////////////////////////////////////////////////////////////////////////
// The one and only application object

CWinApp theApp;

using namespace std;

typedef struct _SOCKET_STREAM_FILE_INFO {

TCHAR szFileTitle[128]; //文件的标题名
DWORD dwFileAttributes; //文件的属性
FILETIME ftCreationTime; //文件的创建时间
FILETIME ftLastAccessTime; //文件的最后访问时间
FILETIME ftLastWriteTime; //文件的最后修改时间
DWORD nFileSizeHigh; //文件大小的高位双字
DWORD nFileSizeLow; //文件大小的低位双字
DWORD dwReserved0; //保留，为0
DWORD dwReserved1; //保留，为0

} SOCKET_STREAM_FILE_INFO, * PSOCKET_STREAM_FILE_INFO;

int _tmain(int argc, TCHAR* argv[], TCHAR* envp[])
{
int nRetCode = 0;

// initialize MFC and print and error on failure
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
// TODO: change error code to suit your needs
cerr << _T("Fatal Error: MFC initialization failed") << endl;
nRetCode = 1;
}
else
{
// TODO: code your application's behavior here.
CString strHello;
strHello.LoadString(IDS_HELLO);
cout << (LPCTSTR)strHello << endl;
}

CFile myFile;
CString filename="123.txt";
if(!myFile.Open(filename, CFile::modeRead | CFile::typeBinary))
{
AfxMessageBox("文件不存在!",MB_OK|MB_ICONERROR);
return 0;
}
CSocket sockSrvr;
sockSrvr.Create(800);

sockSrvr.Listen();
CSocket sockRecv;
sockSrvr.Accept(sockRecv);
SOCKET_STREAM_FILE_INFO StreamFileInfo;
WIN32_FIND_DATA FindFileData;

FindClose(FindFirstFile(filename,&FindFileData));
memset(&StreamFileInfo,0,sizeof(SOCKET_STREAM_FILE_INFO));
strcpy(StreamFileInfo.szFileTitle,myFile.GetFileTitle());

StreamFileInfo.dwFileAttributes = FindFileData.dwFileAttributes;
StreamFileInfo.ftCreationTime = FindFileData.ftCreationTime;
StreamFileInfo.ftLastAccessTime = FindFileData.ftLastAccessTime;
StreamFileInfo.ftLastWriteTime = FindFileData.ftLastWriteTime;
StreamFileInfo.nFileSizeHigh = FindFileData.nFileSizeHigh;
StreamFileInfo.nFileSizeLow = FindFileData.nFileSizeLow;
sockRecv.Send(&StreamFileInfo,sizeof(SOCKET_STREAM_FILE_INFO));

UINT dwRead=0;
while(dwRead)
{
byte* data = new byte[1024];
UINT dw=myFile.Read(data, 1024);
sockRecv.Send(data, dw);
dwRead+=dw;
}
myFile.Close();
sockRecv.Close();
AfxMessageBox("发送完毕！");

return nRetCode;
}

现在应该可以运行了，然后根据你的需要修改

Answer 2

首先你要将文件大小传过去，然后用获得的大小创建文件。然后send文件的内容，记住一定要用recv返回的大小来向文件里写数据
