Read In XML Transform To HTML And Output To WebBrowser Control?
May 17, 2012
I'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>

I 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.

This morning I was trying to work out how to update a User Control from a button on a page using jQuery.Refresh User Control with jQuery.From the info gleaned from this article: http [url]...I now have a method of loading a User Control as a page with jQuery using the converted .VB example from the codeproject.com article.However... this won't render into the browser, Firebug is giving the error "element must be contained within a form runat=server tag" So I posted this question:
re: better way to manage a dynamic select list using jQuery and User Control.Since posting that though,I have thought about it further, and believe it is the fact that the jQuery Handler class created by the codeproject code is send the browser a complete page.Given that I sadly don't really understand what that codeproject code actually does I am having trouble working out how to alter it.What I need it to do is not return a Page at all, but I guess, an HTML string, which can then be pasted directly as HTML into the div as required.how to alter that code to return an HTML string?

I 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?

I 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).

is there a way in vb.net to make it so that if the html in a web browser control contains a certain word then on startup it will show a dialog box. Basically I want to create an update system in which when the update dialog box web browser control html contains the words "update available" then on start up the dialog box will show prompting the user to update.

I 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.

Ok you know how our web browsers like Internet Explorer or FireFox has the option to "Save Page As". Is there a way to do this using the Web Browser Control? I wish to save the HTML + Images that are displayed in my Web Browser Within my application. Or say if I go to a website and they have a dynamic image that keeps Changing is there a way to save that image that is displayed on the Web Browser control?

WebBrowser 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:

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 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:

My VB.NET code is supposed to execute third party Javascript code in an attempt to fill in and submit a form. This process consists of five steps, and I have been able to submit the form when all the steps are kept separate (i.e. behind 5 separate consecutive button clicks). Now, what I'd like to have is one button to handle all the five steps.
The problem is that the form originally only appears after calling "webbrowser.Navigate" command, which apparently modifies the page's HTML code. I seem to be unable to detect when Javascript has finished loading the new HTML in order to fill and submit the form. I have tried a timer control to wait for a certain HTML element ID to appear, but in vain. [URL]

I wrote a VB.Net application that displays HTML help files according to user's search results.A user types some keywords and receives a list of HTML help files containing these keywords.When a list item is selected the HTML file is displayed in WebBrowser control.The problem is that I cannot mark the keywords in the displayed HTML file. I need to highlight them like in a standard Help. I tried many options and nothing works.If I change HTML element style manually (background color for a specific string) all pictures attached to this page are not displayed. After "Refresh" operation the pictures are displayed but the text selection is not enabled.I hope there is a standard function for this operation but I cannot find it.

What I'm trying to do is click an html link inside of a html table via code in vb.net using a web-browser control. The link I want to click can be anywhere in the first column of the table so I need to cross reference with another column in the table to make sure I have the re way I'm going about this is to loop through the html elements till I find the table I want (multiple tables on the page) then dump that table to an array. Then loop through the page again get to the table I want and then start comparing the link and another column in the now array. I need to check to make sure that the url of the link contains a work and that another column in the table contains a specific or lower numerical value. Basically where I'm stuck is while dealing with the html element "Table" wanting to identify and interact with another html element inside it.
'Flag to say dump to array
Dim RecordFiles As Boolean = False
'The last two headers in the table are blank so need to skip them
Dim FirstBlank As Boolean = False
Dim SecondBlank As Boolean = False
