Visual C++ IPtoCountry Sample Source Code

ActiveSocket provides an easy-to-use development interface to a variety of IP protocols. By using ActiveSocket, you can very easily create or enhance applications with network features.

ActiveSocket features the following: DNS, FTP, HTTP, HTTPs, ICMP Ping, IP-to-Country, MSN, NTP, RSH, SCP, SFTP, SNMP v1/v2c (Get, GetNext, Set), SNMP Traps, SNMP MIB, SSH, TCP, Telnet, TFTP, UDP, Telnet, Wake-On-LAN and more.

ActiveSocket can be well integrated into Visual C++ environments. This document describes how the ActiveSocket Toolkit can be integrated into Visual Studio C++ projects.

Step 1: Download and install the ActiveSocket Toolkit

Download the ActiveSocket Toolkit from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

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:

IIPtoCountry * pIPtoCountry = NULL;

Step 4: Create the objects

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

CoInitialize(NULL);

Create the object in the following way:

CoCreateInstance(CLSID_IPtoCountry, NULL, CLSCTX_INPROC_SERVER, IID_IIPtoCountry, (void**) &pIPtoCountry );

Step 5: Perform an IP to country lookup

You can now lookup IP addresses.

The following code shows how to create a simple IP to country lookup utility using Visual C++:
