一个文件传输有关问题，高手请指点啊

请教高手一个文件传输问题，高手请指点啊！
在VC里借鉴了个网友做的服务器和客户端程序，想把客户端移植到EVC下面，出现了编译错误，请高手指点怎么改？？
vc下的客户端程序部分代码是:
[code=C/C++][/code]
DWORD WINAPI CClientDlg::SocketSend(LPVOID lpParameter)
{

HWND hwnd = ((socksend*)lpParameter)->hwnd;
CString sendfname = ((socksend*)lpParameter)->sendfname;
DWORD dwip = ((socksend*)lpParameter)->dwip;

SOCKET socketsend = socket(AF_INET,SOCK_STREAM,0);

SOCKADDR_IN addSrv;
addSrv.sin_addr.S_un.S_addr = htonl(dwip);
addSrv.sin_family = AF_INET;
addSrv.sin_port = htons(8848);


if ((connect(socketsend,(SOCKADDR*)&addSrv,sizeof(SOCKADDR))) == SOCKET_ERROR) //连接
{
closesocket(socketsend);

PrintSystemMsg("连接服务器失败!");

return FALSE;
}
PrintSystemMsg("连接服务器成功!");

//声明文件发送本地变量
SOCKET_STREAM_FILE_INFO StreamFileInfo;
WIN32_FIND_DATA FindFileData;
BOOL bRET = true;
BYTE * sendData = NULL;
CFile sendFile;
CFileException fe;
BOOL bFileISopen = FALSE;
UINT dwRead = 0;

//打开文件
if(!(bFileISopen = sendFile.Open(sendfname,CFile::modeRead | CFile::typeBinary,&fe)))
{
PrintSystemMsg("文件打开失败!请重试!");
goto free;
}

FindClose(FindFirstFile(sendfname,&FindFileData));
memset(&StreamFileInfo,0,sizeof(SOCKET_STREAM_FILE_INFO));
strcpy(StreamFileInfo.szFileTitle,sendFile.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;

PrintSystemMsg("开始发送文件.......");

if(send(socketsend,(const char*)&StreamFileInfo,sizeof(SOCKET_STREAM_FILE_INFO),0) == SOCKET_ERROR)
{

PrintSystemMsg("文件信息传送失败!请重试");
goto free;
}
//发送文件

while (dwRead<StreamFileInfo.nFileSizeLow)
{
byte * data = new byte[1024];
UINT dw = sendFile.Read(data,1024);
if ((send(socketsend,(const char*)data,1024,0)) == SOCKET_ERROR)
{
PrintSystemMsg("文件传输错误!可能网络断开!");
//closesocket(socketsend);
goto free;
}
dwRead+=dw;
delete[] data;
}

PrintSystemMsg("文件发送完毕");
AfxMessageBox("发送成功!");

free:

delete[] sendData;
if (bFileISopen)
{
sendFile.Close();
}
closesocket(socketsend);
WSACleanup();  
return bRET;
}

移植到EVC下的代码是：
[code=C/C++][/code]
DWORD WINAPI CFileTranDlg::SocketSend(LPVOID lpParameter)
{

HWND hwnd = ((socksend*)lpParameter)->hwnd;
CString sendfname = ((socksend*)lpParameter)->sendfname;
DWORD dwip = ((socksend*)lpParameter)->dwip;

SOCKET socketsend = socket(AF_INET,SOCK_STREAM,0);

SOCKADDR_IN addSrv;
addSrv.sin_addr.S_un.S_addr = htonl(dwip);
addSrv.sin_family = AF_INET;
addSrv.sin_port = htons(6000);


if ((connect(socketsend,(SOCKADDR*)&addSrv,sizeof(SOCKADDR))) == SOCKET_ERROR) //连接
{
closesocket(socketsend);

PrintSystemMsg(_T("Connect Serve Fail!"));

return FALSE;
}
PrintSystemMsg(_T("Connect Serve Successful!"));

//声明文件发送本地变量
SOCKET_STREAM_FILE_INFO StreamFileInfo;
WIN32_FIND_DATA FindFileData;
BOOL bRET = true;
BYTE * sendData = NULL;
CFile sendFile;
CFileException fe;
BOOL bFileISopen = FALSE;
UINT dwRead = 0;

//打开文件
if(!(bFileISopen = sendFile.Open(sendfname,CFile::modeRead | CFile::typeBinary,&fe)))
