<div class="content wysiwyg-content">
I'm creating a program in Visual Basic that will launch a particular URL. &nbsp;I need to be able to receive and act upon HTTP server messages. &nbsp;For example I may want to capture and act upon HTTP error 500 - Bad script request or HTTP error 404.<br />
<br />
The StatusTextChange event does fire with each status text change and I can see things like: <br />
<br />
Start download from site: res://C:\WINDOWS\SYSTEM\SH<wbr />DOCLC.DLL/<wbr />http_500.h<wbr />tm<br />
Downloading from site: res://C:\WINDOWS\SYSTEM\SH<wbr />DOCLC.DLL/<wbr />http_500.h<wbr />tm<br />
<br />
I suppose I could parse these text messages looking for &quot;http_500&quot;, &quot;http_404&quot;, etc but I'm wondering if there's a more direct way?<br />

How to capture HTTP server return codes using the webbrowser control with Visual Basic

Web development includes all aspects of presenting content on intranets and the Internet, including delivery development, protocols, languages and standards, server software, browser clients, databases and multimedia generation.

Web Development

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. Hypertext is structured text that uses logical links (hyperlinks) between nodes containing text. HTTP is the protocol to exchange or transfer hypertext. HTTP functions as a request-response protocol in the client-server computing model. HTTP is designed to permit intermediate network elements to improve or enable communications between clients and servers. HTTP is an application layer protocol designed within the framework of the Internet Protocol Suite; it presumes an underlying and reliable transport layer protocol.

HTTP Protocol

HTTPS is a protocol for secure communication over a computer network which is widely used on the Internet. HTTPS consists of communication over Hypertext Transfer Protocol (HTTP) within a connection encrypted by Transport Layer Security (TLS) or its predecessor, Secure Sockets Layer (SSL). The main motivation for HTTPS is authentication of the visited website and to protect the privacy and integrity of the exchanged data. HTTPS is widely used for protecting page authenticity on all types of websites, securing accounts and keeping user communications, identity and web browsing private.
