CFtpGet – FTP File Retrieval Class

Environment: Windows 98, Visual C++ 6

I created this class because I needed a class to allow me to synchronize
my local system with files on a remote system. At first, I looked to MSDN for
help, but couldn’t get their examples to work. Then, I looked to CodeGuru for
assistance. I posted the question of how to retreive a file using FTP and
Ken Sutherland was able to help me.

The source code he gave me worked for only one file transfer at a time so
I modified it for my purpose so that it allows for up to 100 files to
be transferred on one operation.

CFtpGet Class Definition

// ftpget.h

class CFtpGet
{
public:// function, in logical order
 CFtpGet();
 virtual ~CFtpGet();

 // password & user name
 bool SetAccessRight(CString userName,CString userPass);

 // open the connection
 bool OpenConnection(CString server);

 // only one file
 bool GetFile(CString remoteFile,
 CString localFile);

 // a full CString array
 int GetMultipleFile(CStringArray *remoteArray,
                     CStringArray *localArray,
                     int number_file);

 // close the connection
 bool CloseConnection();

private: // var
 CInternetSession *pInternetSession;
 CFtpConnection *pFtpConnection;
 CString strServerName;
 CString strPass;
 CString strUser;

public:
 CString strAppName;
 bool missed[100];
};

Using the CFtpGet Class

To transfer a single file…

CFtpGet ftp; //start the class
ftp.SetAccessRight("username","userpassword");// set user and pasword
bool good = ftp.OpenConnection("server");// the name of the server

if (!good)
 return;

ftp.GetFile("somefile.zip","c:\downlaod\myfile.zip");

// see GetMultiplefile below
ftp.CloseConnection();

To transfer multiple files…

CStringArray remote;
CStringArray local;

remote.Add("remote1.zip");
remote.Add("remote2.zip");
remote.Add("remote3.zip");
local.Add("local1.zip");
local.Add("local2.zip");
local.Add("local3.zip");

ftp.GetMultipleFile(&remote,&local,3);

This is my first Itnernet file transfer class and I’ll try to embelish this class as
time permits.
