I certain html page contains links that are displayed with each onclick event. I am unable to parse the html for the url that will follow these onlick links. If this is the source on the page, how do I capture the content that each onclick link displays. In other words for example:
[Code]....
Now this is the onclick link that will display some content which I need to capture. Basically I want to be able to activate the onclick event from a program to display and capture the url links from that specific page.
I've been programming in VB.NET 2005, 2008 and now 2010 for almost 2 years. Just casual little applications, nothing big.In this project I need to parse links from a web page, it doesn't quite work though, it parses the names only and no links.I'll give you my code, let's say for a random page:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
TextBox1.Multiline = True
WebBrowser1.Navigate("http:www.buyfixuse.com")
[code]....
If I activate this function in my application instead of links to the two blog posts on that website, it only gives out the text that is related to these links - (more...)
There have probablly be thousands of threads just like mine[code]...

View 1 RepliesWhen investigating effective methods of documenting our VB .NET project, by experimentation I discovered that I can make a comment like'See the file at file://path_to_file and I can then ctrl-click on this link to bring up the file in a new tab. Is this feature and perhaps other capabilities of Visual Studio comments documented anywhere? I would like to make a system of documentation consisting of an html pages that link to code, and vice versa.

I am trying to pull a set of html elements from a webpages to copy all the links on the page and toss them into a richtextbox.The tags are <a href "I need everything inside the quotes"but for the life of me I cannot figure out of to work the line of code to accomplish this..
View 2 RepliesI tried using it and to get it to work I had to add some code to my project:
Public Enum HRESULT
S_OK = 0
S_FALSE = 1
E_NOTIMPL = &H80004001[code].....
I didn't like the fact that I had to use the MSHTML stuff (cause I think IE uses it also, and we all know that IE sucks :) ) and that I had to add code the make it work.Don't want to start a browser-war thread so neglect my last remark.Is there a different (/better) approach of parsing html-pages in VB.Net.Basically what I'm trying to do is get all the links (<a> tags) and embeds (<object> tag) on a page.
I'm just curious as to how some software programs that I see out there have the ability to extract links & text from thousands of web pages at an extremely high and fast rate. Has anyone here, ever created a link or text extracting program the has the ability to parse many webpages and return data into a textbox? I know how to extract links via the webbrowser control, but it doesn't seem to parse/extract data at a very high & fast rate like many email, link & text extracting programs that I see out there.

my webbrowser navigates to a webpage. I need to store all the links into a collection, I did find the code to do the job (on this forum) and it works, but there is a problem: there are more links on the page than those the code reads, like when i right click on a picture and choose "copy shortcut" I get a link that is not showing when I display the "view source" for the entire page. I can't figure out how to do it.
View 3 RepliesThis 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?
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 want to do the same that works previously on HTML but now via .NET Windows Forms.When I submit this HTML it works :

I have a basic anchor node as a string and would like to get the URL and the text from it. For example:

How do I code this?
I would like to extract data from a html tag. The html tag is included inside a big html document.
Precisely i would like to extract the value of "txtGUID" from this html tag :

I need to extract some data from a html source [code]...
Now the problem is the words info ect.. wont always be there the content will change so can do something like getelementsbyclass or is there is a way to extract the text between
"<div class="bbcode_quote_container"></div>" and "</div>"
I am using a web browser control by the way
i'm trying to get the following data from within the html tages <td class="colRight">CWCH60</td> where CWCH60 is the data which changes and needs to be extracted. I have tried the following Regex patterns
[^td|<|>|/|class|s|^="colRight"][A-Z|a-z|0-9][^</td>]
[^<td][^s][^class][^="colRight">][A-Z|a-z|0-9][^</td>]
[^tdsclass=""colRight">][A-Z][a-z][0-9]
all work fine in an online regex builder/tester but return WCH60 when executed. Why would this occur, is there a simple operator i have missed out?

View 3 RepliesIn VB.NET 2005, what is the best way to retrieve and parse HTML data from a URL, a bit like a search engine crawler?I am building an app, where I need to parse a website, and collate data from it (the website uses some tags that I could pull out to get the appropriate bits of data). I want to be able to do this in a thread, and just update a DB with the data, and give the client app a status update of the progress.
View 6 RepliesI 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 have saved some HTML pages from the web...now i want to parse some specific data. I mean I want to retrieve some specific part from the HTMl page using VB/C# code. How do I go about it? I am using this code to read the html file..All i want to do now is to save the specifications to the DATABASE.
1. How do i select the specifications and display them in a ListBox??
2.How do i save it to the DATABASE??
Im viewing a form with x amount of data on it, i need to take the data from the webform and place it into a textbox.txtbefore.Text = wb.document.GetElementById("xxxx").InnerTextThats as far as i got, its on a web-page. The id is correct but i cant seem to gather itand seeing how vb.net has a lot of uses for forms it kinda makes it hard to search.
