WebClient.DownloadString Not Getting Whole HTML String
Nov 11, 2010I'm working on a project that scrapes data from government websites. I've noticed that whenever I use WebClient it doesn't always get the whole HTML code. Even when I get the robots.txt file it doesn't return everything. For example, http://www.bbc.co.uk/robots.txt has 80 lines but I'm only getting 13 lines.
If an HTML block uses "display: none" in the style I can't get anything between the hidden HTML blocks.Here is the sample code I'm using:[code]...

VS 2010 Why Does WebClient.DownloadString Remove Part Of HTML's Source
Nov 13, 2011When I go to webcrawler.com and search for something, then look at the source code, a chunk of HTML similar to this displays the search results:
<div id="webResults">
<div class="searchResult webResult">
<a class="resultTitle" data-icl-coi="540" data-icl-cop="results-main" href=[website] target="_blank">[title]</a>
[code]....
But when I use WebClient.DownloadString to read the source code to a textbox, I only get this:
<div id="webResults">
</div>
There's nothing. All of the webresults have been removed.How come I can view the code in my internet browser but not on my application?? I even used an InStr method to confirm that the results weren't contained in the generated code.

Read HTML From A Webpage And Interact With It As Own In A WPF Application?
Apr 24, 2011I've search numerous hours, but I haven't been able to find the appropriate solution. What I want to do: Get the html of a certain webpage (Lets say in this case url...this html within my wpf application, so that you can see the content of the page you requested. Then I want to be able to trigger events on the html that has been loaded from the URL. Like I want you to be able to click on a certain node in the HTML and I want to be able to link this node to a certain value. Basically a crawler application that let's you request a page, see the page in a control and allows you to click in the loaded HTML and link values to predefined values you set. So basically I want to be able to get a webpage displayed within my application and be able to trigger events on the html (For example a click on the html which would need me to know on what node you clicked in the html, or for example be able to edit the html by clicking in it).

Anyway, in VB6 I used Inet to get the source of a PHP page that had the current song that was playing on the SHOUTcast stream. I can't seem to get Inet to work and figured I would just look for another method so I wouldn't need to pack msinet.ocx along with the finished product.
How can I get the source of the PHP page and store it in a variable or textbox/label.
