How can I access the HTML source of IFrame within a page by using WebBrowser control?
View 4 RepliesI looked all over the forum posts here and didn't see the answer to a question concerning iframes within the webbrowser control (there were similar issues however). The forum has a classifieds section that allows members to post threads daily. I have a message that I like to send once every day to a forum and decided that it would be best to achieve this programmatically. However, I noticed in the visual basic 2008 webbrowser control, that it doesn't seem to automate the iFrames within the browser using the htmlelementcollection codes.

I am using a Webbrowser control to sign into Hotmail. Then once it is signed in then I'll just use this navigate code to open the inbox: I think that the problem is that the actual inbox(mail window) is within an iframe. I have to figure out how to call within the iframe. If you can goto hotmail and sign in and you'll see once your in the inbox when you view source it isn't the inbox's source but then when you right click then goto this frame then view the source to the frame it is.

I want to find a url webbrowser control inside iframe.
1) my webbrowsercontrol opena url
2)that url has one iframe inside it
3) That Iframe has a link which I want to grab programmatically using vb.net
First off I hope I'm in the right forum.I have an application I built with the WebBrowser control in Visual Basic 2005. I am using the DocumentComplete event to track when a page has fully finished loading as some of the webpages I need to work with have frames.
The problem I am having is that when some iframes time out or don't load, the documentcomplete events stop firing. So if my webpage has 2 frames on it, we'd expect 3 documentcomplete events. One for each frame and one for the parent document once the frames have loaded. If say frame 2 does not load properly, the documentcomplete event for the overall document never fires.
I have a facebook iframe app I'm trying to test using a WebBrowser Control on a form in VB.NET 2010. Whenever I try to access the WebBrowser.Document.Window.Frames frame object on a document where my app is showing in the broswer, I get an Access Denined exception. Reading around on the web, I see people saying that this is to keep scripts in a document from accessing content in iframes that are pulling content from another domain, as per [URL] for security reasons.
While I totally understand why this is done for the general public, how can I disable it on my machine so that I can run these tests? I can't properly test my app without doing it in the facebook iframe and using the WebBrowser control is the only way I know to do this test programmatically. I'm on windows server 2003 and ie8, .net4.0, if that helps. I own the domain where the app is, and its in AS.NET MVC2, so if there's anything I can do to the web code to enable this??? I also removed the Internet Explorer ENhanced Security COnfiguaration component, but that didn't help.
I have a program Which can get the frame's content, but if it is iframe I got error, normal frame with no problem, I need to detect the frame is iframe or normal frame.... but fail...

View 3 RepliesHow can I access data that WebBroswer1.navigate function is downloading from a website, while it is downloading it? If I access it once it has finished downloading it through the WebBrowser1_DocumentCompleted function, it only slows down my program, since it has to wait for the website to finish downloading to the control before I can access it.
View 2 RepliesI have been trying to use the WebBrowser control to access a website, nothing fancy involved, just a Security Certificate error message I can't get around:
The site that I've been trying to access is [URL].. By clicking on the "Login" hyperlink you are taken to a https connection.Internet Explorer simply allows you to click on the "Continue to this website (not recommended)" link which displays the Logon screen.Clicking on the same link in a WebBrowser control simply reloads the page as (I assume) WebBrowser has not been told that the page is ok.
I've tried looking around for the solution with no luck, it seems like such a simple problem..
I am trying to access a browser control in one of my forms from a module but keep getting an error. I attached a screen capture showing the code and the error balloon.

View 3 RepliesI have a question about the webbrowser control that I hope someone can answer. I am working on a document retrieval and storing class that uses HTML to display and save data. I want to use the webbrowser control in winforms using VB.Net. I only want to store the fields values in the html document, not the whole document. I am hoping to use labels in html and read them with the DOM of the web browser control but am not sure how to do this.
Has anyone done this before and could someone please provide some sample code on how to do this?
I'm trying to access a secured website using vb 2005 and webbrowser control. I've got the credentials, the script can pass the login page but when trying to navigate to the second page within, the page is being redirected back(to the first page after logging in). The second page I'm trying to get to retrieves the data from a database and displays some options for the user to select in order to prepare a report which can be downloaded after the fields selections. And I wanted my script to do this automatically without user interaction.

View 11 RepliesI have been using GreaseMonkey for Firefox for about a year now and I find it wonderful, but I am really prefer using VB over JS and I would like to do some stuff that is on my computer along, not on the internet.I wrote some script for GM that read the contents of an iframe, and GM allows you to "include" which addresses the script runs on. This is really nice because it keeps the script from running where you don't want it to, AND it allows cross-domain support for communication between dom elements (in a round-about way).
I want to get away from using GM because I like some of the stuff I have already done in VB over the last 10 years and dont want to rewrite it all. So really I want to go back to my old stuff and learn how to get this functionality from VS2008.What I am specifically looking for is HOW in the world does GM listen for the creation on the window objects and run some script on it when it is finished?
Lets say I have a few webbrowser objects or other non-active xml, html or dom objects in my project. I want to retrieve info with one, send info with another, and display info with the actual webbrowser object.It sounds weird and I bet it could be used maliciously, but I mean no harm. Like I said, Ive been doing it for a year in GM already. I know .net really tries to prevent this kind of stuff cross-domain, but I figure if GM can do it, anybody can. The question is just how.
I understand how to access dom elements and all that, and I have some skill listening for events. I am just a little lost on how to combine the two in this situation. Grabbing an iframe is simple, and I realize I cant (shouldnt be able to) read it when I am acting in the parent object's domain. How do I sequester the iframe window away from its parent object once its loaded, or at the point before it loads its content so I can read it or more specifically add an event listener so I know when its finished loading? This seems super simple, my brain must just be addled.
I want to listen for the creation of the iframe from the project level, and I want to be informed of the document load from project level. I dont want to listen or do anything from the parent window object, so I really want the iframe sequestered as much as possible. Assume all iframes I will be dealing with are not of the same domain as the parent object.
I'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.
