在Windows编程，常涉及到操作FTP的需求。
以下为个人总结的一些示例代码：
1 //
2 //*********************************************************
3 //Ftp basic operation

6 //
7 //1. connect to ftp
8 //
9 BOOL flag;

11 CString cstrFtpUserName = TEXT("pdmug"); //user name
12 CString cstrFtpPassword = TEXT("pdmuguser"); //password
13 CInternetSession* m_pInternetSession = NULL;
14 CFtpConnection* m_pFtpConnection = NULL;
15
16 try
17 {
18 m_pInternetSession = new CInternetSession();
19 m_pFtpConnection = m_pInternetSession->GetFtpConnection(cstrFtpServer,
20 cstrFtpUserName, cstrFtpPassword, 21); //21 --- ftp port
21 }
22 catch (CInternetException* pEx) //error:can not connect to specific ftp
23 {
24 if (m_pInternetSession != NULL)
25 {
26 delete m_pInternetSession;
27 }
28 if (m_pFtpConnection != NULL)
29 {
30 delete m_pFtpConnection;
31 }
32
33 return;
34 }
35
36 //
37 //2. get current directory
38 //
39 CString cstrCurrDir;
40 flag = m_pFtpConnection->GetCurrentDirectory(cstrCurrDir);
41 if (!flag) //get current directory error
42 {
