Visual Basic 5.x/6.x HTTP Get and HTTP Post 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.

HTTP Get and HTTP Post can be well integrated into Visual Basic 5.x/6.x environments. This document describes how the ActiveSocket Http object can be integrated into Visual Basic 5.x/6.x projects.

The most important functions of the Http object are:

  • Connect - connect to the (remote) HTTP web server on port 80 or any alternate port; optionally, use proxy credentials to use a proxy server; optionally, specify a web account and password for password protected web sites
  • Disconnect - to diconnect after a connect call;
  • ReadData - read all data from a web page;
  • WriteData - write data to a web page.

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 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 2.4 Type Library' reference as shown in the following picture:

On top of your code, declare the following object:

Public objFtpServer As ASOCKETLib.FtpServer

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 objHttp = CreateObject("ActiveXperts.Http")
