I'm trying to write a function that can retrieve all the links from a webpage. I'd like to send only a string containing the URL. Basically, given a string of a URL, I'd like to "load" that into an HTMLDocument so I can access the Links collection. I just can't figure out that part.I've already written the function by using the Document in a WebBrowser. But, after selecting a link, I'd like to get its links, and so, and so on....while the user is still browsing the first page.
In my project i want to search a word in 10 different music sites and return all the links on the site, the problem is that i can't convert a string to a htmldocument.[code]
I'm able to retrieve the source code of a web page and store it in a string variable. I would like to cast that string variable into an HTMLDocument if possible, to make parsing its elements much easier.
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.
This line is throwing the error; Public WithEvents CurrentDoc As mshtml.HTMLDocument Researching the error tells me that HTMLDocument isn't fully qualified. Isn't this fully qualified? If I change it to Microsoft.mshtml.HTMLDocument then it says it's not defined.
I'm trying to get all <A> and <IMG> tags from the webresponse I got from [URL]. Basically Im trying to get a collection of all links and images in an html string.
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.
I would like to read a file from disk ( TEMP.HTM ) and convert it to a System.Windows.Forms.HTMLDocument.I know that I can set a WebBrowser control to Navigate to the file and then get its .Document property, but is there a better way, possibly using something in the System.IO.File space?
i want to be able to get all links from the current webpage, and then take the ones that have a certain part of the url. How can i do this. Basically I want to:
1) Get all the links
2) Delete the links that do not contain "/article/"
3) Put those links in a textbox.
I know how to do number 3, but how can I do number 1 and 2?
I got a small issue. Im trying to grab some links(about 5 only) from a webpage that can change frequently.
Im using:
For Each ClientControl As HtmlElement In wb.Document.Links ListBox1.Items.Add(ClientControl.GetAttribute("href")) Next
It gets the value of the link the files are (the hyperlink) and allows me to download the file, but I want to get to get the string assocaited with it as well
For example, A link says click here! and bring you to a page.
I can get the link to the page, but not the text click here according to my source code.
I'm actually trying to code a downloader for a site that generate download links.The program can download one link, but when there are more than one link, it only downloads the first one.
Bascially, all i'm trying to do is change the value of an attribute (such as the TARGET attribute of an A anchor tag) to "_TOP" if the attribute exists, if it doesn't exist, (if IsNull returns True) then I just create the attribute and set the value to "_TOP".The problem is, it almost always sets it without quotes around it, and even if i try to set it with quotes by setting .value = Chr(34) & "_TOP" & Chr(34) then what it does is it sets SINGLE QUOTES around the quotes I place (it's like a bad joke) and turns up in the HTML as '"_TOP"' (lol), and if I set it normally, its just saved as <a href="..." target=_TOP>some link</a> (without quotes).[code]I've changed the above variable names & turned vars into strings ("target") etc to make it easier to read for anyone reading.
I have wasted heaps of hours on this, MSDN docs are as usual horrid, there is no real documentation or tutorial on this stuff either. I've even tried using .nodeValue instead of .value to do the setting, but makes no difference. Also, I've tried (in the Else section) removing the attribute and re-creating + re-adding it from scratch to see if this would make a difference, but it didn't.Of course, quotes are important because if you try to perform an action (call a method) on this element or use it later, you will get the dreaded "unspecified error". I do this through the WebBrowser Control in VB6, but same principle should apply everywhere... C#/.NET/JavaScript etc as it seems to be DOM related).since posting we realized that if we pass the attribute name in uppercase, then the value is saved with double quotes around it. although this is not a real solution (just a temporary one), i am still looking for answers if anyone has one and accepting any thoughts you may have about this in this post. However, the temporary solution has created another sub question, being a post about the problems that arise from using this temporary solution. The sub question related to this temporary solution is located at the following link for those who may find it useful or interesting to read about, and for those who would like to contribute to this discussion further: Must pass uppercase to set MSHTML element attribute (.setAttribute) correctly, why? And CaseInsensitive .setAttribute doesn't work
I have one sample project to automate Internet explorer in VB 6.0. The same thing when I am trying to do with .Net its just hangs my Internet explorer document. I am not able to type or click on any control on the page.
Here is the sample code block.
[Code].....
Even i am not able to fire any htmdoc_focusin or focusout of DOM which was really easily accessible from my VB code.
I am creating a program and have the following code to extract the URL's off of a webpage and put them in a richlistbox. This is only from one page. The problem is that I am only getting one URL into the listbox, instead of all of them off of the page.
Here is what I have so far:
Private Sub Timer3_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer3.Tick Dim str1 As String = WebBrowser1.DocumentText
I have a WebBrowser1 control and two TextBox(1,2).The First TextBox1 is used to load Urls to the webbrowser.After the WebBrowser completed to load the web page,I just want to write the urls (http:/........) of the links in the web page in the second TextBox2.The links can be a buttons or images, so insted of clicking on them I want to access them by the program.How can I write the urls of the links from the webbrowser on TextBox2?
I know that I can select an option in a listbox within my HTMLDocument (which refers to a webbrowser control's HTMLDocument) using SetAttribute. For example:
However, I can't figure out how I can select multiple items within the listbox. When I call SetAttribute repeatedly, it always unselects the old one first.
I was trying to use HtmlDocument and a given url to pull in the html contents of a website to use. However there is no constructor for HtmlDocument and it's Url property is readonly. Is there any way to create an object that contains the entire DOM for a given url?
I need to Read a HTML File and retrieve Tag value and attribute value.In HTMLDocument there is no LOAD function to load a html file,but there are methods like getElementByTagName.How to load a html file in htmldocument class?
Is it possible to load HTML content into the HTMLDocument object without having to use the WebBrowser control? I have an html file stored locally that I want to parse in order to find out which checkboxes are on and which are off.
All of the examples I've found use the Webrowser. It just seems convoluted to have to use the WebBrowser in order to get to a DOM object.
I'm trying to get my program to go to the memberlist.php of a phpBB2 forum and gather all the links to the members websites. Example: [URL] I want the program to go to that website and save all of the websites (the ones that have the "www" image) to a list inside the program. I have no idea how to do this, but that's not all, considering most forums have several pages of members (this one has 32 at the moment) it has to go through all of the pages and gather all the links from every page..
I can't figure out how to make my web browser open links in a new page or tab instead of IE. I've tired at least a dozen different sets of code. None of them can be manipulated to fit my browser. When my browser first starts, there's an empty tab control. I put a new webbrowser in it at runtime and set it's dock to fill. I create new instances of the browser for new tabs as well. I just can't find how to make it open links in new windows.

I am currently redeveloping my web browser application using the axWebBrowser component. I have, up to now, managed to port most of the code from my previous application, which used the standard webbrowser component. How would I retrieve a list of links from the current web page displayed in the axWebBrowser and display them in the DataGridView? The following code from my previous application is giving me an error. [Code]
What I'm trying to do is parse out some links via a google search and fill a text box with said results. This is the code I have in a module which I call upon inside of a command button.
