Network Communication Toolkit for Windows Developers

FTP Upload Download component for C++ for Windows

ActiveSocket is a Network Communication component for Windows Developers. It runs on any 32 bit and 64 bit Windows Platform, incl. Windows 7, Windows 2008, Windows 2003, Windows 2000, Windows Vista and Windows XP.
It features many IP protocols, incl.: SSH (Secure Shell), RSH (Remote Shell), HTTP(s), FTP, ICMP Ping, NTP, SNMP v1/v2c (Get,GetNext,Set), SNMP MIB translation, SNMP Trap Sender, SNMP Trap Receiver, Telnet, DNS, TCP, UDP, IP-to-Country, Wake-On-LAN and more. Samples are included many popular development platforms, incl. Visual C# .NET, Visual Basic .NET, ASP .NET, Visual Basic, Visual C/C++, ASP, Java, Javascript, PHP, Borland Delphi, Borland C++ Builder, ColdFusion.

ActiveSocket can be well integrated into Visual C++ 5.x/6.x environments. This document describes how the ActiveSocket FtpServer object can be integrated into Visual C++ 5.x/6.x projects.

The most important functions of the FtpServer object are:

  • Connect - connect to the (remote) FTP server on port 21 or any alternate port;
  • Disconnect - to diconnect after a connect call;
  • GetCurrentDir - retrieve the current directory;
  • ChangeDir - change the current directory;
  • CreateDir - create a new directory;
  • RenameDir - rename a directory;
  • DeleteDir - delete a directory;
  • FindFile - find a specific file in the current directory;
  • FindFirstFile - iterate over all files in the current directory; find the first file;
  • FindNextFile - iterate over all files in the current directory; find the next file;
  • RenameFile - rename a file in the current directory;
  • DeleteFile - delete a file in the current directory;
  • GetFile - get (download) a file, either using binary transfer or ASCII transfer;
  • PutFile - put (upload) a file, either using binary transfer or ASCII transfer;

Step 2: Create a new Visual C++ project

Launch 'Microsoft Visual C++' from the Start menu, and choose 'New' from the 'File Menu'. The 'New' dialog appears.

Select the type of project (for instance: 'Win32 Console Application'), enter a 'Project name' and select the 'Location':

Select the kind of project, for instance a 'Hello, world!' application and click 'Finish':

Step 3: Refer to the ActiveSocket Library and declare the objects

A new Project is created now.

Before you can use ActiveSocket, you need to refer to the ActiveSocket library. The actually reference files are shipped with the product and are located in the following directory: 

   
C:\Program Files\ActiveXperts\ActiveSocket\Examples\Visual C++\Include

Copy all files in the above directory ('ASocket.h', 'ASocket_i.c' and 'ASocketConstants.h') to your project directory.

On top of your code, declare the following object:

    IFtpServer	*pFtpServer = NULL;

Step 4: Create the objects

Since the ActiveComport Toolkit is a COM object, you must initialize the COM library before they can call COM library functions (e.g. ActiveComport functions): 

   CoInitialize(NULL);

Create the object in the following way: 

   CoCreateInstance(CLSID_FtpServer, NULL, CLSCTX_INPROC_SERVER, IID_IFtpServer, (void**) &pFtpServer );
