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)
doc.LoadHtml(TemplateHTML)

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]

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean

I am creating a Windows Application in VB.Net 2.0. The application is an FTP transfer application, where I need to display 2 panes. On the first pane, I need to display the client folder structure and on the other pane, I need to display the remote FTP server. Most of the functionality is complete, but I am stuck on 2 places.
1. I need to display a combo box on top, similar to the one we have for Windows Explorer Address bar (where we can see My Computer, Desktop, Network Places, Drives, etc.). I have searched a lot but could not find something matching my requirement other than a few 3rd party controls which I need to purchase (I am looking for something open-source).
2. I am using ListView Control to display the files list. I need to show icons for "My Computer", Network Places and desktop on the List View, which I am not able to do. Is there any way I can display these Icons and make them work exactly the way Windows Explorer does?
How can I retrieve a number of images from a directory on my website, and place them in a directory on my computer.

I have never written anything like this before, so I am not even sure where to start.
