NTP stand for Network Time Protocol. It is a protocol for synchronizing clocks of remote hosts and computers over the internet or internal network. NTP is based on UDP port 123 (non-reliable IP protocol). It is designed to resist time latency.

ActiveSocket can be well integrated in Visual C++ 6.x projects. This document describes how ActiveSocket can be integrated in Visual C++ 6.x 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':

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:

    INtp	*pNtp = NULL;
