I 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.

View 2 RepliesI 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.

How can I access the HTML source of IFrame within a page by using WebBrowser control?
View 4 RepliesFirst 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.
Basically I just want to set up exceptions for my program to prevent errors. The problem I am having is that sometimes the field name does not exist. For example, I am setting focus to the username text field named simply "username". However, if the entry does not exist (name=username) then I get an error. So what I need is a simple if statement to determine if it exist beforehand.
If Webbrowser1.Document.All("username").Exist Then
WebBrowser1.Document.All("username").Focus()
else
Messagebox.show("Field was not found!")
End If

View 9 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.
