Use MFC to write FTP programs

 

 

1. Generate the CInternetSession variable.

 

CInternetSession ses;

 

2. Open the FTP connection.

 

CFtpConnection * pFTP = ses. GetFtpConnection ("ftp.microsoft.com", "user", "password", port, FALSE );

 

3. open the file.

 

CInternetFile * pF = pFTP-> OpenFile ("abc.exe ");

 

It is simpler to use

 

CFtpConnect: GetFile (...); CFtpConnection: PutFile (...); you can copy files.
