[Code]...
Is it possible to obtain these input elements during an httpwebrequest without having to view the html code?
I understand the basics of httpwebrequest and I'm not looking for any answers on web browsers. My previous method was done using webbrowsers but because of the lack of speed I have transferred over to httpwebrequest to speed up the process.
I have an id of an element that I would like to grab and use in an httpwebrequest but not sure where I would start with that.
differences between HttpWebRequest and WebClient and why I should use either.
View 1 RepliesI am working on a Geocoding app where I put the address in the URL and retreive the XML. I need the complete XML response for this project. Is there any other class for downloading the XML from a website that may be faster than using WebClient or HttpWebRequest? Can the XMLReader be used to get the full XML without string manipulation and would that be faster and/or more efficient?

View 4 RepliesI'm using the following code to set the proxy on an HTTPWebRequest:
Dim proxy As New WebProxy("HOST:PORT")
...Then...
' Goto the final URL
request = CType(WebRequest.Create("[URL]"), HttpWebRequest)

Now I put in a valid Proxy, don't run into any problems applying it, but IPChicken will always return my IP address, not that of the proxy.
I'm looking for a way to fill in various website details using a HttpWebRequest/WebClient. I can manage it quite easily using an invisible WebBrowser control, by manipulating the HtmlDocument, but for some reason I just can't quite grasp the way I would do it with a HttpWebRequest/WebClient. I've heard both of these can potentially submit info using the UploadData functionality etc, but I'm missing specificsI've done a lot of searching on google just for a basic example to get me started, but the only one that LOOKED informative was written entirely in German.Take, for example, this website. Let's just say I wanted to automate filling in my username and password into their respective boxes and then pressing the "submit" button. How would I start going about this, and how do I get the resulting page? (I'm assuming cookies that the page creates will keep your next webrequest going)

I decided it's time to migrate from VB6 to VB.NET and am currently translating my radio player but have run into several issues so I might be on this forum for the rest of the day... 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.
I was doing cross-domain ajax calls from an HTML-only (no server programming) page, to a PHP backend on a different domain. I realized at one point that I couldn't do POST with cross-domain, so I figured I needed a local proxy. Unfortunately, PHP is not available on that domain so I have to resort to ASP.NET.So I built a very quick & dirty vb.net proxy... It works, except for one very important detail. If any of my form fields contain HTML, the data is not sent to PHP (or PHP doesn't receive it, I'm not sure). Actually, the $_POST variable exists, it's just empty all the time as soon as it contains what looks like html code, such as <p>. That same field, if it doesn't contain an HTML tag, will work fine and the data is passed on to the PHP page. [code]
Oh the PHP side, all I'm doing is $var = $_POST["htmldata"]; , and $var is always empty. I'd give an example of my PHP but I don't know that it's necerssary. $_POST["action"], for example, contains the correct action I'm expecting, so it's not the PHP code itself that's wrong.Well, if you encode the HTML so html entities are correctly passed on (not as <), it works!
I'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]...
When I use this code:
Dim dloadurl As Uri
Dim saveto As String
Public Sub dodownload()
Try
[code]....
why the code below fails to retrieve the html
Dim WebReqeust As WebClient = New WebClient
Dim URL as string = "http://www.professionalorganizervannuys.com"
Dim WebPage As String = WebReqeust.DownloadString(URL)
It fails on this particular URL.
I am trying to get source code from a webpage. Webbrowser control is giving me the required information that I am looking for. But I want to use httpwebrequest but its giving me different source than webbrowser documenttext.

I am scraping title of webpage. i am using webclient class to get its html source. the true title of webpage is this which apprear on browser "La rvolution" but when i extract it from html source using webclient class i get following string. "La rvolution du sourire juste"
I think its something related to string conversion. how to convert this "La rvolution du sourire juste" to "La rvolution"?
Following info on webpage might give you some clue which is content type. " <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />"
When 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.
I need to grab some data from a webpage but for me the main problem is I can't grab the data the way I want.

I am giving the format (source) of the webpage below and my coding in vb.net (2008),

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">

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?
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 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.
then fill all tags and attribute of this page in vb arrayi know this is too much but would you expl
