i am trying to get the value from this code:

Dim theVidURL As String = doc.DocumentNode.SelectSingleNode("//DIV[@id='lcm_simlive_countdown']").Attributes("value").Value
But it tells me Object reference not set to an instance of an object.
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!

I am creating an HTML document using HTML agility pack. I load a template file then append content to it. All of this works, but when I view the output file it has removed the closing tag from my <br/> tags to look like this <br>. What is causing this?
Dim doc As New HtmlDocument()
doc.Load(Server.MapPath("Template.htm"))
Dim title As HtmlNode = doc.DocumentNode.SelectSingleNode("//title")

I ended up just reading in my template file as a standard string then loading the html like this
Dim TemplateHTML As String = File.ReadAllText(Server.MapPath("Template.htm"))
TemplateHTML = TemplateHTML.Insert(TemplateHTML.IndexOf("<div id=""topContent"">") + "<div id=""topContent"">".Length, _
html.ToString)

There seems to be no documentation on the codeplex page and for some reason intellisense doesn't show me available methods or anything at all for htmlagilitypack (for example when I type MyHtmlDocument.DocumentNode. - there is no intellisense to tell me what I can do next)

I have to pull out particular fields from cells in an HTML table. Using Firebug I was able to get the exact XPath to the cells I need (unfortunately, the cells don't have an id tag). I thought I could use DocumentNode.SelectSingleNode and pass in that path, but it doesn't seem to be working right. What am I doing wrong? Or is there a better approach to this than how I am doing it? Unfortunately, I have no experience with XPath so this is turning out harder than I expected it to be. Here's what I have so far (I know the HTML is particuarly messy, but that's not in my control to change):[code]

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">
</td>

Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?

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).

View 1 RepliesI'm compiling and testing the VB programs in a download from MS of the Windows API Code Pack at url...(which is in VS 2008 and needs to be converted to run on VS 2010). So far I've resolved most of the issues, but a couple are baffling.The code as downloaded for the Taskbar demo refers to icons in the project resources as My.Resources.Green and My.Resources.Yellow and Red. Fatal errors, even though all the help pages say this is the correct way to access them. I got the build to run by removing the "My."; has there been a syntax change between VS 2008 and 2010? When I run the app, I get a message from TaskbarDemo.vshost.exe which says "This demo application needs to register .txt files as associated files to properly execute the Task related features. Filetype is not registered." Does that mean that in trying to debug the app, I have to modify the registry to associate the test program with the .txt filetype?

<p>Translation companies are

<h3 class="this_class">mind blown site</h3>
There is no </p> tag so i cannot parse it completely. Now i have two questions :
1) can this be parsed using httpagility xpath ?
2) i have a function to find text between two strings (getbetween). But i have a doubt - If i use "asdasdasd" and " is it always 100% that vb.net will use the script tag which is just above h3 because there are 2-3 same lines - "asdasdasd"
