HTML Form SNMP MIB Browser Sample Source Code

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

Network Component 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.

Network Component can be well integrated into any development platform that supports ActiveX objects.

SNMP MIB Browsing can be well integrated into ASP .NET environments. This document describes how Network Component's SNMP MIB Browser can be integrated into ASP .NET projects.

A management information base (MIB) is a database used to manage the devices in a communications network. The database is hierarchical (tree-structured) and entries are addressed through object identifiers (OID's). A MIB should contain information on these commands and on the target objects (controllable entities or potential sources of status information) with a view to tuning the network transport to the current needs. Each type of object in a MIB database has a name, a syntax, and an encoding. The name is represented uniquely as an OID. An OID is an administratively assigned name. The administrative policies used for assigning names are discussed later in this memo.

Use Network Component's 'SnmpMibBrowser' object to load a MIB database into memory and iterate over all objects and view all properties.

Step 1: Installation of Network Component

Download Network Component from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

When using HTML, there are two ways to install the Network Component on a client PC:

Automatic installation using HTML code

  <object codebase="" 
           classid="CLSID:B52B14BA-244B-4006-86E0-2923CB69D881" ></object>

The Network Component will be installated automatically. The user will be asked to confirm the installation, because the DLL is coming from an untrusted site (

There are two ways to avoid prompting:

Manual installation using the Network Component installation procedure

On each client PC, download the Network Component from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.

Step 2: Create the Network Component object in HTML/JavaScript

You must use Javascript to declare and create the objects.

Use the following Javascript code to declare and create the object:

var objSnmoMibBrowser;
objSnmoMibBrowser  = new ActiveXObject ( "AxNetwork.SnmpMibBrowser" );
