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.

  • CInternetSession() argument missing

    Posted by Legacy on 01/11/2002 12:00am

    Maybe it's new with version 6.0 of Visual Studio, but I show the second argument of CInternetSession() as being the context. You have

    CInternetSession(strAppName,INTERNET_OPEN_TYPE_PRECONFIG);

    and it should be

    CInternetSession(strAppName,dwContext,INTERNET_OPEN_TYPE_PRECONFIG);

    Of course, this only matters if you are looking to use CInternetSession::OnStatusCallback(), as the default value for the CInternetSession() is INTERNET_OPEN_TYPE_PRECONFIG.

    Anything in a lower directory is reported as missing.

    Am I missing something?

  • Retreive file attributes from remote system

    Is it possible to retreive only those files that are not opened ? In other words, is it possible to read file attributes from the remote system ?

    Hi,

    i use the Visual C++ 6 FTP-Classe to get some File file from a mainfraime!
    But i have one Problem. The mainfraime does use a different codepage as the PC.
    If you take the DOS-FTP under Windows NT, you can use the command 'quote site sbdataconn=(ibm-273)'!
    I have not find out, where i can use this command under MFC!
    Maybe you have got a idea?

    Regards
