View 4 RepliesWebClient.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]...
Replace With HTML Ascii Codes?
Apr 2, 2009I ran into a problem. Wrote the following code snippet:
teksti = teksti.Trim()
teksti = Replace(teksti, "<", "& lt;")
teksti = Replace(teksti, ">", "& gt;")
teksti = Replace(teksti, """", "& quot;")
teksti = Replace(teksti, "'", "& #8217;")
[Code]...
After writing this I realized it becomes its own problem. The function is supposed to make information safe for HTML and SQL injection (there are other methods too, parameterized queries, etc but that's beside the point). However what happens, is that it first replaces < with & lt; and then proceeds to replace the newly written string again as every replace string has &, # and ; signs in it.
I thought about using a regex for this, but I couldn't find any decent Visual Basic examples that were simple enough. Edit: I was sure there would be a "smart" easy way to do this, but I guess there are no common methods available after all. The re-arranging the problem cases first is the obvious solution here,As for parametirized queries, checking back I see my English doesn't come out as intended. I meant to say that I'm already using them, that this problem here is specific to prevent all manner of html-injection and possible sql-injection using the same strings elsewhere later.

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.

Html Source Code Doesn't Show Html But In Firebug Inspect Element Html Is There?
Jan 10, 2012This 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>
[Code]...
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?
Sending An HTML Email, Where The HTML Comes From An HTML File .Net/ClickOnce Environment?
Jun 20, 2009Usage: 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).
Giving A Command To An Exe?

Code:
Dim returnValue As Process
returnValue = Process.Start(readValue)
to launch the game.(The readvalue is a string that reads the location from the games registry entry)Is there anything I can add on to use the direct IP conect command or is a whole diferent piece of code all together?

Html - VB Basic RegEx - Save Value From An Input Tag In HTML Source Code
Feb 16, 2011I am trying save a value from an input tag in some HTML source code. The tag looks like so:
<input name="user_status" value="3" />
I have the page source in a variable (pageSourceCode), and need to work out some regex to get the value (3 in this example). I have this so far: [Code] Which works fine most of the time, however this code is used to process source code from multiple sites (that use the same platform), and sometimes there are other attributes included in the input tag, or they are in a different order, eg:
<input class="someclass" type="hidden" value="3" name="user_status" />
I just dont understand regex enough to cope with these situations.

Xml - Stop Automatic HTML Encoding When Assigning To HTML Input Fields?
May 6, 2009I have to submit a HTML form to a 3rd party website and one of the hidden fields is an XML string. The XML needs escaping before it is sent to the 3rd party.
However when I add the plain XML to the form field it semi-escapes it for me. So then when I use HTMLEncode myself part of the XML is double-escaped. How do I prevent the automatic escaping that appears to becoming from .NET.
Or even better how else can send the escaped XML via the hidden field.
XML
<systemCode>APP</systemCode>
Basic assigning to hidden input field
<systemCode>APP</systemCode>
When I HTML Encode it as well
&lt;systemCode&gt;APP&lt;/systemCode&gt;
I can see what's happening - but I don't know how to prevent it?
