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 into VB environments. This document describes how ActiveSocket can be integrated into VB projects.

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

A new Project is created, with a blank form.

First, you must add a reference to ActiveSocket in the project to be able to use the object. To do so, choose 'References...' from the 'Project' menu. In the 'References' dialog that pops up, enable the 'ActiveSocket 3.1 Type Library' reference as shown in the following picture:

On top of your code, declare the following object:

   Public objNtp As ASOCKETLib.Ntp

Step 4: Create the object

From the Code window, select 'Form'. The Private Sub 'Form_Load()' will be displayed now. In the 'Form Load' function, create the object in the following way: 

   Set objNtp = CreateObject("ActiveXperts.Ntp")
