What is the URL in the document that you have loaded? If you have just
a form with a webbrowser in it, and you go to that document, do you still
get that error?
Do you have any browser helper objects which could be interfering with
the page? That's my first guess, since the WebBrowser control is really
just a managed wrapper around IE (more or less).
Nicholas,
I'm jumping in here since I run into a similar problem.
I use the code below to retrieve DOM element infos from websites.
In one of my apps, I get the unauthorizedaccess exception in some
websites, especially those who need a login (webmail stuff and so on)
On others however the code below works just fine. I played a little
around with ExecutionContext and Security Settings, but with no
success. Any hints how I should proceed ?
here is part of the code, no interaction with the website is needed, I
just collect the entire tags.InnerHTML info
Thread newThread = new Thread(new
ParameterizedThreadStart(LogInnerHTML));
newThread.SetApartmentState(ApartmentState.STA);
newThread.Start((IHTMLDocument2)ie.Document); //ie is a
valid InternetExplorer instance used to navigate to the url
newThread.Join();
......
internal static void LogInnerHTML(object inputParam)
{
string output = "";
IHTMLDocument2 document = (IHTMLDocument2)inputParam;
IHTMLFramesCollection2 frames =
((IHTMLDocument2)document).frames;
IHTMLElementCollection documentTags = document.all;
foreach (IHTMLElement tag in documentTags)
output += tag.innerHTML + "\n";
if (frames.length != 0)
{
for (int i = 0; i < frames.length; i++)
{
object index = i;
IHTMLWindow2 window =
(IHTMLWindow2)frames.item(ref index);
IHTMLDocument2 frameDocument = window.document;
IHTMLElementCollection allTags =
frameDocument.all;
foreach (IHTMLElement myTag in allTags)
output += myTag.innerHTML + "\n";
}
}
}
thx a lot
Ulf
