Network Communication Toolkit for Windows Developers

HTTP Get, HTTP Post software 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.

HTTP Get and HTTP Post can be well integrated into Visual C++ 5.x/6.x environments. This document describes how the ActiveSocket Http object can be integrated into Visual C++ 5.x/6.x projects.

The most important functions of the Http object are:

  • Connect - connect to the (remote) HTTP web server on port 80 or any alternate port; optionally, use proxy credentials to use a proxy server; optionally, specify a web account and password for password protected web sites
  • Disconnect - to diconnect after a connect call;
  • ReadData - read all data from a web page;
  • WriteData - write data to a web page.

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_Http, NULL, CLSCTX_INPROC_SERVER, IID_IHttp, (void**) &pHttp );
