用CFtpConnection类里面的OpenFile和CInternetFile类里面的Write可以自己控制每次写入的大小，从而设置进度条，这种方法绝对可以，下面是部分代码，如果有不明白的可以邮箱问我oicqhf@tom.com
CInternetSession* pSession;
CFtpConnection* pConnect;
CInternetFile* pFile;
pSession = new CInternetSession(AfxGetAppName(),1,PRE_CONFIG_INTERNET_ACCESS);
pConnect = NULL;
pFile = NULL;
try{
pConnect = pSession->GetFtpConnection(m_szFTPServer,m_szFTPUser,m_szFTPPass,m_nPort);
}catch (CInternetException* e) {
m_nErrorCode = e->m_dwError;
m_szError.Format("Connect Ftp server failed,the error code is:%d",m_nErrorCode);
AfxMessageBox(m_szError);
e->Delete();
pConnect = NULL;
return;
}
CFile file;
if (!file.Open(m_szLocalFile,CFile::modeRead))
{
m_szError.Format("Open % file failed!",m_szLocalFile);
AfxMessageBox(m_szError);
bSuccess = FALSE;
break;
}
DWORD nLength = file.GetLength();
BYTE* pBuf = new BYTE[nLength + 1];
file.ReadHuge(pBuf,nLength);
file.Close();
pBuf[nLength] = 0;
int nPart = 0;
nPart = nLength/1024 + 1;
m_Progress.SetRange(0,nPart);
m_Progress.SetPos(-1);
UpdateData(FALSE);
pFile = pConnect->OpenFile(m_szServerFile,GENERIC_WRITE);
for (int j = 0;j < nPart;j++)
{
BYTE* pTemp = pBuf + j*1024;
try{
pFile->Write(pTemp,1024);
}catch (CInternetException* e) {
m_nErrorCode = e->m_dwError;
m_szError.Format("Upload %s file failed!The error code is %d!",m_szLocalFile,m_nErrorCode);
AfxMessageBox(m_szError);
bSuccess = FALSE;
break;
}
m_Progress.SetPos(j+1);
m_nPos += 1;
m_allProgress.SetPos(m_nPos);
}
pFile->Close();
delete pBuf;
