Forms :: Alter Webbrowser Src Code Before It's Done Loading?
Dec 9, 2009
there's an img src=blah on a web page that I am loading with a webbrowser control, and I want to alter it to say img src=blahblah instead ... What I've been doing so far is waiting for the document to complete, doing a .replace, then saving the file to the hard drive, and finally navigating to that local altered version.I was wondering if it's possible to skip the step of replacing and reloading the local page, and instead, just dynamically alter the original source code of the page AS it's loading the first time. Can this be done?

Is it possible to alter or add to the VB code through a form?
I have a combobox that has a list of over 3000 vendors. The edit list that comes with combobox will only hold a little over 1700 lines, so I used the combobox1.items.add to the (form1 events - load) code. Now I have access to all 3000 + vendor names in the ComboBox1. But if I design an add vendor form, how would I code it, so the vendor would be added to the bottom of the items.add list in the code?

I need to get the url of the webpage the webbrowser is navigating to, but since the code executes faster than the webbrowser navigates to the webpage, it gets the url of the last page. I cant use DocumentComplete Event because i have a tabbed browser,
and i cant write events because im creating tabs(with webbrowsers) at run-time. So how would i check to see if the webbrowser has loaded a document?

Is 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.

I 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)".

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 currently have a main page called "ShowFrames.php" that has this html code in it:
[Code]...
I have loaded "ShowFrames.php" onto my WebBrowser1 control and it loads both of the frames onto the webbrowser control. Now my question is, how can I get the source of either of the iframes WITHOUT loading that frame by itself? For instance, when you load 2 frames on a screen in Firefox, it lets you right click on it, and select "This Frame" > "View Source" so you can view the sources separately. Can anyone tell me how I can duplicate this and put the source in variable strSource? I know that to get source code for a page, you need this WebBrowser1.Document.Body.InnerHtml But I dont know where to go from there in order to get a specific iframe's source.

I 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.

I am designing a yahtzee game in Visual Basic. I am wanting to save the form's background color and the picture boxes dice so they can be set the next time the form is loaded. The user can change the background color of the form and choose between several sets of dice. I want the last color the form's background color was and the picture of the last set of dice used placed back in the picture boxes of the dice the next time the user opens the Yahtzee game. I am trying to do this in a module, with generic collections of all the picture boxes on the form. Am I able to do this before the form loads?
