Extract The Page Source Of A Webpage ?
Jun 6, 2011
Basically I am building a webcrawler and in order to do so
I have to extract the page source of a webpage which I can do so like this:
CODE:
The above code works fine on most of the websites I have tried to extract page source from but for some reason it is failing to extract the html contents of few websites like these where the message posted by a user is nowhere to be seen? The webpage in question is this: [URL]
Is there something I have missed or is it due to forum protection etc which is preventing the vb application from extracting the whole page source?

My application is intended to crawl a URL page and extract all possible links from the page.It works fine for a certain URL but with another it keeps causing problems. When the root page is accessed it correctly extracts the different directory links. but when it requests the directory links html page it pulls the main root URL again. someone mentioned about redirection but when debugging I see the url variable containing the directory link correctly.

I have the following code to open a webpage:
Dim IE As Object
Dim x As Integer
Dim c As Variant
[code]....
The page that opens is in xml and in that xml there is the "page_count" that I need to pick out so I can tell my macro when to stop looping. I have dimmed it as "c" in the code above. Following is the XML.
<search>
<total_items>360</total_items>
<page_size>100</page_size>
<page_count>4</page_count>
Somehow I need c = "4", which is the "page_count". Does anyone know how I can pick out the "4" from the xml on my page?

I know that .NET has several classes to do that, but sometimes I need to download a webpage that requires login, like a forum. I do not want users to fill in their sername/password in my application, because I know I'll get a lot of complaints about that. WinInet handles cookies automatically (if the user is logged in with Internet Explorer), but WebClient, HttpWebRequest and WebRequest don't.In my VB6 application I show a messagebox, telling the user that the webpage can't be downloaded the 'normal' way, but if they want, that the application can still download the webpage if they are logged in with IE.This is the VB6 code slightly modified. It works fine until it gets to the line:
vb.net
iResult = InternetReadFile(hInternet, sBuffer, BUFFER_LEN, lReturn)
I think something is wrong with the InternetReadFile declaration.

Been working on a Web Browser in VB 2008 Express, and so far things have been going good. I have run into a little problem though. I have a menu bar at the top of the browser as normal and one of the items selects is "View" and then under that "Page Source".
Now, i have added the following code and it works as expected but one problem. When the box opens to display the web page source it has no scroll bars, minimize or maximize buttons to manipulate the page.
Private Sub PageSourceToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PageSourceToolStripMenuItem.Click
Dim pagelSource As String = WebBrowser1.DocumentText
MsgBox(Me.WebBrowser1.DocumentText)
End Sub
I think the problem is that I am using "MsgBox" . Would there be a better way to do this?

I am trying to extract everything between the body part as I am building a forum crawler
and since all the user posts are between the <body></body> I have chosen to experiment
with Regex. So far I have coded the following but sort of stuck on how to output the result say in a textbox? Also I am not sure if the body part of the regex is correct.
Dim URL As String = Textbox1.Text
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("URL")
Dim response As System.Net.HttpWebResponse = request.GetResponse
Dim streamReader As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())
