Read HTML From A Website Using The WebBrowser Control?
Nov 25, 2010I have a website that divided into 4 frames. I'm trying to create an application that will constantly run on my PC as a task looking for certain text in the HTML in a frame.When it finds the text it would alert the user by presenting a pop-up message. This is basically a monitoring website that checking network nodes. Instead of staring at the screen looking for critical messages I would like to be notified when there is an alert.

May 17, 2012I'm probably missing something really simple or trying too much at once but it's 16:30 on a Friday afternoon and my head is wrecked Basically, I'm trying to build an application that takes out put from a database query as XML and uses XSL to transform it into HTML which is then displayed in a web browser controll on another form.
I thought I break it up into pieces so I decided to just create an XML file and an XSL stylesheet and read this into the web browser control but all I'm getting is <HTML></HTML>

Forms :: WebBrowser Hide HTML Elements?
Dec 14, 2010I developed a WebBrowser which loads a certain web-site for me. The next task, I would like to see only a certain info on that web-site which acts like a table serving as special informational news for me. So, I don't want another things to be appear on my loaded web-site. I need to hide html elements, so that don't appear on my loaded web-site. So, then the form will be like smaller and it will be more convenient to use. Maybe, I need also to hide or remove some java scripts. Do you have any recommendations for it?

Html - Dynamically Created Elements From Codebehind Need To Be Inserted Between Specific Elements
Sep 17, 2010I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

View 1 RepliesFrom HTML Content In A WebBrowser Control, Call Another Control?
Feb 20, 2010I have a regular application form with a WebBrowser control.I have strung together a .htm file (from a regular text file) which I then assign to the WebBrowser control. In the html file, I have filenames mentioned.I am trying to string together the html in such a way as to give a clickable link or button that will parse into html and open the corresponding file in another WebBrowser control in VB.I have tried using VBScript and JavaScript to put a button in the html.As long as the function or sub I call is also in the same html document, it works, but I really need to transfer the control back into visual basic where I can do the heavy lifting I need to.can I just not do this as a regular VB application? Any way to do it without adding the complication of requiring ActiveX?

Jan 26, 2011I am currently trying to be able to set the HTML in a WebBrowser control. The bit that I am having the trouble with is that when I go to put the HTML in the WebBrowser control on Form.Load or Form.Activated the WebBrowser1.Document.Body is Nothing. This means when I try to do; WebBrowser1.Document.Body.InnerHtml = value I'm getting an exception as I am trying to use it.I have also tried setting the HTML on the DocumentCompleted event for the WebBrowser control, but that event doesn't fire when I load the form (to be honest I didn't think it would but it was suggested somewhere on the Internet).

VS 2005 Want To Load Some HTML Into A WebBrowser Control
May 18, 2011I want to load some HTML into a webBrowser control, then operate a particular bit of code when it has finished loading.The code operates fine as long as I pause to wait for it to finish loading. If I just run the code without pausing, it sometimes messes up the display. webBrowser.Document Completed doesn't run after Document.write.I don't want to use webBrowser.DocumentText = "..." because that makes an annoying click sound every time it refreshes. A lot of people are annoyed by this. There are countless threads asking how to turn off the click, and using .write seems to be the only solution that doesn't require hacking the registry.

Loading HTML Content Into A WebBrowser Control From Memory?
Oct 4, 2005WebBrowser Example.zip IntroductionBecause the WebBrowser control that we use in .NET is a COM control, not all of its uses are straightforward and some of them (even those which seem like they should be easy) require that we dip into our Interop toolbox in order to properly implement them.
A perfect example of this is loading HTML content into the WebBrowser from memory, rather than a file or a URL. Anyone who's ever used the WebBrowser control before is familiar with the Navigate2 method, which tells the control to load content from a URL (or path to a file). Loading HTML content from memory, however, is a rather elusive practice because of the many steps involved in making it work.
MSHTML.HTMLDocumentYou might notice that the WebBrowser control exposes a "document" property. The object returned by this property can be coerced to the type of "mshtml.HTMLDocument" (you must add a reference to MSHTML to your project in order to make this work) as follows:
Code:Dim clsDocument As mshtml.HTMLDocument = CType(WebBrowser.Document, mshtml.HTMLDocument)
(NOTE: You will have to add a reference to the COM library MSHTML to your project to make this compile)
Once we create an instance of HTMLDocument, a whole new world opens up to us, providing all sorts of DOM access to the content of any given Web page.
If we were to create our own HTMLDocument object from memory, we could use the "write" method to write HTML content to the document from a string variable, like this:
Code:'initialize the document object within the HTMLDocument class... clsDocument.close() clsDocument.open("about:blank")
'write the HTML to the document using the MSHTML "write" method... Dim clsHTML() As Object = {sHTML} m_clsDocument.write(clsHTML) clsHTML= Nothing
WebBrowser Control ImplementationUsing the HTMLDocument returned by the "document" property of the WebBrowser control, however, is not as straight-forward. Because of the way that this object is created and initialized in memory (by the COM WebBrowser control), the "write" method fails when called as above. In order to write content to the HTMLDocument exposed by the WebBrowser control, we must first marshal the string value to a memory space that is compatible with COM. Once the string is properly marshalled, the COM interface IPersistStreamInit (implemented by the HTMLDocument class) must be used to pass the value into the object.
Interop DeclarationsIn order to pull all of this off, we must declare several Interop pieces, including an enumeration, a function, and two interfaces. The declarations for these pieces are as follows:

VS 2005 Loading HTML Into HTMLDocument Without Using Webbrowser Control?

Webbrowser Control - HTML Page With Embedded JavaScript?
Jun 5, 2009I am using a Webbrowser control to access the elements in an HTML page which contains a JavaScript link which when clicked, adds extra content to the page. This works fine in IE 7 and Firefox.I then want to access this extra content in my program. Having found the HTML element containing the link, I tried element.InvokeMember("click"). I have used this successfully with a submit-type link to login to the web site, but cannot get it to work with the JavaScript link. I also tried setting the focus to the link element and using SendKeys to send the ENTER key, but all to no avail. Nothing seems to happen. I don't see the extra content produced by the JavaScript, nor do I get an error.Here is an extract from the HTML, showing the relevant (I hope) code:
