当然支持

CInternetFile::Seek
virtual LONG Seek( LONG lOffset, UINT nFrom );
throw ( CInternetException );

CInternetSession* m_isSession;
CFtpConnection* m_ftpConnection;
CIntetnetFile* hFtpFile;
m_isSession=new CInternetSession(AfxGetAppName(),1,PRE_CONFIG_INTERNET_ACCESS);
try{
m_ftpConnection=m_isSession->GetFtpConnection(...); //看MSDN
}catch(CInternetException* pEx)
{..}這裡面MSDN都有這個代碼.
hFtpFile=m_ftpConnection->OpenFile(filename,GENERIC_READ,FTP_TRANSFER_TYPE_BINARY,0);
...
用hFtpFile->Seek(是完全可以的..因為是CFile繼承的
..關閉
if(hFtpFile)
{
hFtpFile->Close();
delete hFtpFile;
hFtpFile=NULL;
}
if(m_ftpConnection!=NULL){
m_ftpConnection->Close();
delete m_ftpConnection;
m_ftpConnection=NULL;
}
if(m_isSession !=NULL)
{
m_isSession->Close();
delete m_isSession;
m_isSession=NULL;
}
