Borland Delphi SNMP 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.
SNMP can be well integrated into Borland Delphi environments. This document describes how ActiveSocket's SNMP objects can be integrated into Borland Delphi projects.
ActiveSocket is compliant with SNMP v1 and SNMP v2c. ActiveSocket automatically detects which SNMP version is running on the remote agent. Different SNMP data types are supported, including:
- String types (also called "octet strings");
- Integer types (16bit, 32bit, 64bit and unsigned integers);
- IP Address types;
- Timetick types;
- Counter types (32bit and 64bit counters);
- OID types (also called "Object ID's");
- Other, less frequently used datatypes.
The following operations are supported:
- Get - retrieve an object variable from the (remote) agent;
- GetNext - retrieve the next object variable from a table or list within an agent;
- Set - set values for object variables within an agent.
Prerequisites
IMPORTANT: Make sure that the SNMP Service is installed and running on the machine where ActiveSocket is installed. For more details, please read FAQ items Q1200010 and Q1200015.
Step 1: Download and install the ActiveSocket Toolkit
Download the ActiveSocket from the ActiveXperts Download Site and start the installation. The installation guides you through the installation process.
Step 2: Create a new Delphi Project
Launch Borland Delphi (for instance 'Delphi 2005') from the Start menu. Choose 'New' from the 'File' menu and select your preferred kind of application, for instance: 'VCL Forms Application - Delphi for Win32'. A new Form is displayed in the workspace.

Step 3: Refer to the ActiveSocket Library and create the objects
Now that a new project has been created, you must add a reference to ActiveSocket in the project to be able to use the ActiveSocket object. To do so, choose 'Import Component...' from the 'Component' menu. The Import Components' dialog appears. Select 'Import a Type Library':

The interface code is generated now and is shown in the ASOCKETLib_TLB tab of the project.
Step 4: Declare and create the object
From the Project Manager, open Unit1.bas and add the ASOCKETLib_TLB to the 'Uses' statement to refer to the ActiveSocket library:

In the 'private' or 'public' section, declare the following objects:
objSnmpManager : ISnmpManager
You can now create the objects, for instance in the 'FormCreate' function:
objSnmpManager := TSnmpManager.Create(Form1).DefaultInterface;
