WebRequest - Proxy Authentication Required

I started using .NET 2003 and my first application is to parse an HTML form.
But I am behind an ISA firewall and get "(407) Proxy Authentication
Required" with the following code. The proxy settings in webReq.Proxy
appear to be OK, even without setting them as below. IE works, but this
does not. Any ideas? (or where to ask?) -- David

Dim webReq As WebRequest = WebRequest.Crea te(txtUrl.Text)
webReq.Proxy = WebProxy.GetDef aultProxy
Dim webResp As WebResponse = webReq.GetRespo nse
Dim sr As New StreamReader(we bResp.GetRespon seStream, Encoding.ASCII)
Dim html As String = sr.ReadToEnd()
sr.Close()

David,

You may want to set the Credentials property of your WebRequest object.

Sorry, I should have mentioned that I had tried that too with no success.

Hi I was wondering if it's possible to use the WebRequest class to access a file on windows shared folder with authentication? If yes, what would the syntax be? I've tried to look this up in the references available but to no avail Also, is it safer (better practise) in an LAN environment to use HTTP requests to access shared files (via ASP.NET) rather than UNC file shares TIA Regards John

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...
