Jan 30, 2011
I am working on my application that I am reading the strings through html page using with httprequest. All I am trying to achieve by find the value using with the matches which come next equals, something is like: "Address=Whateveritgoeshere". So I want to extract to get the strings which it would be: "Whateveritgoeshere"
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Address of URL
Dim URL As String = "http://mysite.com/getInfo.asp?id=" & Textbox1.Text
[code]....
However when I deug to run the application, I have got an empty returned strings. Do you know why I have got an empty returned strings?If you think that I have done something wrong then how I can only extract the strings that come next to the "Address="?

I am using visual basic 2005. I found on the web the following function that extracts HTML from webpages. It is very useful but unfortunately it does not work with redirected pages. That is, when I put in it a URL of a redirect page it gives me nothing or error. I added to it ".AllowAutoRedirect = True" but still it did not work. I wonder how to make it work for redirected pages.

I'm looking for an efficient means of extracting an html "fragment" from an html document. My first implementation of this used the Html Agility Pack. This appeared to be a reasonable way to attack this problem, until I started running the extraction on large html documents - performance was very poor for something so trivial (I'm guessing due to the amount of time it was taking to parse the entire document).[code]...

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 know how to extract an entire page source into VB.NET, but once I do that how do I make VB.NET search the text and return a specific vlaue that is not constant?
Take this line from the page source for example:
<td id="actualPriceContent"><span id="actualPriceValue"><b class="priceLarge">$4.30</b></span>
the text is always constant but the price is not - how do I make VB.NET return the price?
