I was trying to use HtmlDocument and a given url to pull in the html contents of a website to use. However there is no constructor for HtmlDocument and it's Url property is readonly. Is there any way to create an object that contains the entire DOM for a given url?

View 5 RepliesIs it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.
All of the examples I've found use the Webrowser. It just seems convoluted to have to use the WebBrowser in order to get to a DOM object.
if i create an instance of an object/webpage, is that a complete new object/page based on the original or does it does it just make it accessible? i am almost sure that it creates a new object/page but i would like confirmation. in other words what is the result of this code?
dim Page2 as new Page1
dim Page3 as new Page1
would this create 2 new pages that i can "customize" separately and add different controls to each? heres a brief description of what i want to happen:the user will be viewing Page1 and when he clicks btnCreate i want a page that i created in the designer to be shown and its name and other variables to be determined by what the user chose for room options in Page1. i need "new versions" of this page to be created because multiple users will be creating multiple rooms. i understand that there are more lines of code involved in creating pages and i do have more questions regarding those but i will wait until i confirm that dim Page2 as new Page1 will create a new page. like i said im sure that this does create a new page but i need confirmation. also if it does create a new page, how do i get it to show. i know that response.redirect will redirect me to a dif page but i want show this new room on top of the old one.
I would like to read a file from disk ( TEMP.HTM ) and convert it to a System.Windows.Forms.HTMLDocument.I know that I can set a WebBrowser control to Navigate to the file and then get its .Document property, but is there a better way, possibly using something in the System.IO.File space?

How can you programmatically get a websites inner html? I found a way of getting the html of a site, but dont know how to get the inner html.
View 11 RepliesI've search numerous hours, but I haven't been able to find the appropriate solution. What I want to do: Get the html of a certain webpage (Lets say in this case url...this html within my wpf application, so that you can see the content of the page you requested. Then I want to be able to trigger events on the html that has been loaded from the URL. Like I want you to be able to click on a certain node in the HTML and I want to be able to link this node to a certain value. Basically a crawler application that let's you request a page, see the page in a control and allows you to click in the loaded HTML and link values to predefined values you set. So basically I want to be able to get a webpage displayed within my application and be able to trigger events on the html (For example a click on the html which would need me to know on what node you clicked in the html, or for example be able to edit the html by clicking in it).

I need to create a VB.net app that automatically reads a html table. It should connect to a web address (eg "[URL]") and read it. I'll be happy if I could just get the full HTML. I was able to use this code to get the HTML of a regular website:
Dim strReply As String = "NULL"
Dim objHttpRequest As HttpWebRequest
Dim objHttpResponse As HttpWebResponse
objHttpRequest = HttpWebRequest.Create("[URL]")
objHttpResponse = objHttpRequest.GetResponse
Dim objStrmReader As New StreamReader(objHttpResponse.GetResponseStream)
strReply = objStrmReader.ReadToEnd()
This code sample will give me the HTML for the website [URL]. However it will not work with the website I want (eg "[URL]"), because when you access it via regular browser it will popup a browser dialog asking for credentials (user / pass). So when I run the code above for it, I'll get the exception:
The remote server returned an error: (407) Proxy Authentication Required.
How do I set this up to use the credentials, before retrieving the HTML? This is actually my first web-related app.
For some odd reason, when I download text files, the HTML of the web page is being appended to the text! All other file types work fine!Here's the code that's doing the download:
Public Sub DownloadBlob(ByVal Blob As Byte(), ByVal FileName As String, ByVal Response As HttpResponse)
Response.AddHeader("content-disposition", String.Format("attachment;filename={0}", FileName.Replace(" ", "_")))
Response.ContentType = String.Format("application/{0}", Path.GetExtension(FileName).Substring(1))
Response.BinaryWrite(Blob)
End Sub

I have used .NET and ShDocVw for years to grab data off webpages without any issues I couldn't overcome. This website has me beat though. It seems like such as easy task to grab the titles and other information off a library search page, but I can't see the data to be able to grab it. Usually, I just look in the DOM, but the data wasn't there. I did a view source, but the data wasn't there.

View 3 RepliesI decided it's time to migrate from VB6 to VB.NET and am currently translating my radio player but have run into several issues so I might be on this forum for the rest of the day... Anyway, in VB6 I used Inet to get the source of a PHP page that had the current song that was playing on the SHOUTcast stream. I can't seem to get Inet to work and figured I would just look for another method so I wouldn't need to pack msinet.ocx along with the finished product.
How can I get the source of the PHP page and store it in a variable or textbox/label.
