Need a bit of help with HTML Agility Pack!Basically I want to grab plain-text withing the body node of the HTML. So far I have tried this in vb.net and it fails to return the innertext meaning no change is seen, well atleast from what I can see.
Dim htmldoc As HtmlDocument = New HtmlDocument
htmldoc.LoadHtml(html)
Dim paragraph As HtmlNodeCollection = htmldoc.DocumentNode.SelectNodes("//body")
[code]....
I have tried this:
Return htmldoc.DocumentNode.InnerText
But still no luck!
The method I'm currently using to extract html and the parse is via a WebBrowser control.I'm grabbing a collection of tags, sorting through the ones I want, and then pulling the innertext.Doing this on my development machine is kind of slow, but manageable. At max, I can go through 60 different web pages across 3 different sites. It takes about 5 mins on my machine.
However, this app is targeted towards machine that have a quarter of the technology that my computer has. So, it takes anywhere from 10-15 minutes. This is less than ideal.I've bee reading up on the documentation on HTTPWebRequest. However, form what I've seen I can't seem to find a way to grab the HTML and then parse it with a method from HTTPWebRequest.
Due to the way I'll be using it, I won't be able to use RegEx to parse the data and was hoping there was a method within the HTTPWebRequest property to do it.
I am having trouble extracting links from a web page and it involves javascript running on a website that contains the url links i need. I have encountered this issue before and was able to resolve it by getting the javascript file and then parsing it for the links. However this time I am unable to find the javascript that contains the links.To better clarify here is the source code segment from the web page:
<li><a href="javascript:void(0);" onclick="javascript:changeViewMode('Detailed', false); javascript:getTopTenStatsData(this, 'PlayerStats','HR'); javascript:changeMainCategoryLinkClass('liPlayersLink'); ">Highest-Rated Members</a></li>
<li><a href="javascript:void(0);" onclick="javascript:changeViewMode('Detailed', false); javascript:getTopTenStatsData(this,

Does anyone know of any other method that I could do that would take less resources and perform a lot quicker?

I want to extract some information from a web site (Bloomberg). This side has a search textbox with a onKeyUp event that, as far as I can understand, uses AJAX to create a table. Is it possible to insert some text in the textbox and then get the table created with AJAX? Given the source code of the page with the tabled already AJAXed (If you understand what I want to say here), I can easily retrieve the table. I just need to get the source code with the table already on it.

I am trying to create an application to make self-extracting Exe's in Visual Studio 2010 Express. I would like to have a box in which files can be dropped into, then when you click "Compile" it will compress all files dropped into the box along with 3 others I must have delivered to this self-extracting exe. When the newly created exe is run, it will launch "Install.exe". I know there are other items out there to build the self-extracting exe's. I would however like to make my own that always delivers these 3 specific files along with whatever is dropped into the application.

Ok I got a variable named Accounts and stores the user accounts. They are seperated like this
Account|Pass|Admin&Account|Pass|Admin
As you can see after admin there is a symbol (the &) meaning that before the & its an account and after it its another. In other words its like this
Account|Pass|Admin
Account|Pass|Admin
so how can I make a loop to count how many & there is in the Variable named Accounts?

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">

Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question. The users understand to use absolute link and image references when sending an E Newsletter. Environment:
AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).
I'm trying to create a small program, which I think will be helpful to others(in here). My aim is to convert the English text shown in screen to Malayalam. English-to-Malayalam conversion is not a problem. But the problem is, how to extract the text from the screen. In most of the converter/translator, the text needs to be copied or written down in the translator tool. But my program will cut off that part. That is, simply move the program window (having a rectangle hollow portion) to the English word that needs to be converted. And upon pressing a button (or autodetect), the English word is converted to Malayalam.
So, my question is how to extract the English text(or words) from the screen (which is seen through the hollow portion of the window.
Here's a screenshot of what I'm trying to do.
