C# - WebBrowser Control: Disable Cross Site XSS Filtering Or Another Way To Process JS In Full On HTML?
Jun 25, 2011
I am trying to use my web browser control to get retrieve date from a specific page, including all sub-page content. Problem is some of the sub-pages are on a separate domain and thus I am getting a permission deigned error when i try to access the frame [through document.windows.frames(i).document].Is there any work around to do this, even if I have to manually change security settings? I tried turning all my settings in IE to allow and still same error. I will only be running the app locally and no one will be browsing on IE so I can literally change anything needed to get this to work (even install older version of IE which may allow it but can still handle JS processing).
Note the reason I am using web browser is a great majority of data I will be accessing is JS generated, so I need to access the DOM after JS processed / generated the HTML. Because of this, simply using SOCKETS to get the HTML is really not an option. Even if I had the HTML, I still need some type of engine to process all of the DOM elements based off javascript.

Tried to look for a solution for this problem everywhere and can't seem to find it?I have found solutions related to sub-classing the document, but this method results in a Null Exception as there is no document.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
AddHandler Me.WebBrowser1.Document.ContextMenuShowing, AddressOf WebContextMenuShowing
WebBrowser1.ContextMenu.Dispose()
WebBrowser1.ContextMenu.Show(WebBrowser1, pas)
End Sub
[Code]...

I am confused what will happen, when I disable a timer. Will it finish the process and then disable or will it immediately disable without completing process? for example
[Code]....
I want to run getMessage from somewhere else, so I need to disable timer during that time to be asured not to override anything and also before timer disable it should complete that function code.

in my form load, I have the web browser control navigate to a site. What I'm trying to do is when a user clicks button1, i want the program to look through the webpage and check if there is an image source equal to a static URL that I assign. this is basically just navigating to a website & checking if a certain link exists.

I have a webbrowser control on a form and try to navigate to one specific site. It seems to me that the remote detects that call is from a desktop program and redirect it. Is it possible? and if it is how I can hide it.

I am using an embedded webbrowser control to access a third-party website, populate the username and password boxes on their front page, and login. The problem I have is that the resulting window that the site returns to me is in the form of a new window. What I want to do is capture this window and all it's session/cookie data in to the original webbrowser control, as even if I direct the original window to the same resulting url, some kind of authentication data is missing and the site tells me I have logged out, even though the popup window works fine. I need that page in the original control so that I can continue to access it programmatically, and I don't really want to get in to the complication of accessing the new window, as I expect I'll have to delve in to the api or something.

I have been googling for hours and trying to figure this out, and I just can't.I have 1 webbrowser control on a form, webbrowser1. Once I load a page, say google.com, if I use webbrowser1.refresh() or webbrowser1.navigate("google.com"), it's not reloading the page, it has it cached so it's just reloading the cache. This is terribly apparent especially on pages like forums or craigslist.

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 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 made a web browser using the Visual Basic Language. I am having a problem with the WebBrowser Control.If I go to a website that runs scripts (i.e.; sports.yahoo.com), a message comes up:"An error has occured on this script page", Do you want to continue running Scripts on this page "yes, no". If you click yes or no, the same message appears for 8 more times. Is there anycode I can use to disable the "Script Error Message" from appearing in the WebBrowser Control.

1. Is there any way to disable refreshing in such a way that the button can still be used for stuff like flash on the page still? All my methods have blocked using the button in the flash which is loaded on the page....
2. Is there any way to get the new scrollbars of IE10 or metro style scrollbar or what not into the webbrowser like the desktop version of IE10 does in Windows 8 Consumer Preview?
3. Is there any way to allow the close window called from javascript to be detected & actually close the window in my program?
4. Is there any way to make it so when new window is called it will open a new window with my application in a new instance? stopping me now is it seems to want to open in the same window if I use the event NewWindow to cancel the event from happening but it gets script errors....is there any way to retrieve the link to what it needs to open so I can handle this properly? Or at least tell it what else to use? besides the default browser....I want it to open inside my own program & not IE.

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).

I have been attempting to automate a process in a webbrowser control. When I attempt to fill out the form and submit, I get a false negative response (meaning all the data in the fields are correct but I am getting an incorrect response back from what I should be getting). I have determined that this problem is due to the fact that when I manually type out the data in the input fields a javascript is being fired. I know that you are able to invoke the javascript, but as I have no real knowledge about javascript and the script is rather complex I am stuck.
A temporary solution for me has been to use SendKeys, but this is no real solution at all. If the window loses focus, the entire process goes out the window. I cannot just use the .SetAttribute or .InnerText methods for the elements in the window.
I'm not sure if any of you are familiar with WatiN but I have used it recently while looking for other means to do what I need to do here. Watin works, but instead of allowing me to use an embedded browser object it shells new browser windows. Anyhow, with WatiN I am able to minimize or hide the browser window and the code will still execute. This leads me to believe that there is a way to simulate keypress events in a browser window while making sure that the specific element is the active element.
I have searched all over the internet for this (but am sure I overlooked a few things in frustration) and have yet to find a solution that works for me.

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.
