WebBrowser Control - Possible To Disable Image Loading?
Sep 6, 2007Is it possible to disable image loading on the webBrowser control? - So that pages load faster. I just want the HTML of the page to work with in my code - I don't wish for the page to be displayed. And I know that using httpwebrequest or webclient would normally be the best option for this kind of thing but I need to browse secure https pages and I don't know if that's possible with anything other than the webBrowser control.

Jan 19, 2012I am using web browser control in one of my forms for displaying html files (local files). Before I load the next file I want to clear the webbrowser control of the previous page. I am trying the following method which I found while searching the net.
private Sub ClearWebBrowser(ByVal wb As WebBrowser)
Dim tempDoc As IHTMLDocument2 = CType(wb.Document.DomDocument, IHTMLDocument2)
tempDoc.write("")
tempDoc.close()
End Sub
I have added the reference for mshtml namespace in com tab. When trying to run the program, error is thrown like "Type 'IHTMLDocument2' is not defined. (BC30002)".
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?
Aug 17, 2009Is 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.
Waiting For Webbrowser Control To Finish Loading Page?
Dec 25, 2011I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.

VS 2008 Webbrowser Control?
Jun 17, 2009I'm attempting to load a website, look through the HTML, and then put it into a control.When I do this, the site redirects to another page. I know how to pull the info, so I need to figure out how to get to my destination page. I'll break it down in steps:
1. Attempt to load www.site.com/1
2. If cookie is not on machine, site redirects to www.site.com/zip code.
2b. Enter Zip code
3. Attempt to load destination site again.
4. Page redirects to www.site.com/default.aspx
5. Attempt to load www.site.com/1
6. Success
If the cookie is already on the machine, it skips to step 3. No matter what, it always loads the default.aspx page first. This isn't a webbrowser control issue, it's a site issue. This happens when on a normal browser.I'd hate to say it's bad coding standards just because it's not working because I want it to, but it sure seems like bad coding standards.

VS 2008 Webbrowser Control And Deleting Cookies?
Jun 3, 2009I'm having an issue trying to pull information from a specific website. I've asked about this once before, but had no luck through searches or responses.In a nut shell, the issue I'm having is trying to pull information from several URLs from a site.When I load the first URL and pull the information, it works just fine. But if I want to pull another from that same site, it acts like it is loading, but doesn't pull the information. In order for me to gather that information, I have to restart the program, but that beats the purpose.So, I wanted to see if the issue was related to cookies or something else the webbrowser control creates when loading a site. If this is the case, I'd like to clear out this information, or at least try it, after each time it pulls the information from the site.
