Re: What's wrong with this small code - getting the DOM

2005-12-01 Thread Vijay 
The process crashes on the last line
nsresult nres = mEndParent->GetChildNodes(getter_AddRefs(children));

I can see in my vstudio debugger that I am getting an object with this
structure:

nsIDOMDocument
  nsISupports
__vptr
  (**some expression which can't be evaluated)
  (**some expression which can't be evaluated)
  (**some expression which can't be evaluated)

Thanks,
Vijay

Er... what?  That doesn't look to me like it should do anything sane at all.  In 
particular, after this code runs in your example as:


nsCOMPtr doc;
pBrowserFrame->GetBrowserImpl()->GetDOM(doc);

|doc| will be null as far as I can tell.

Hi All,

In the original code of mfcembed, I have changed this method -

void CMfcEmbedApp::OnNewBrowser()
{
CBrowserFrame *pBrowserFrame = CreateNewBrowserFrame();

//Load the HomePage into the browser view
//if(pBrowserFrame && (GetStartupPageMode() == 1))
//pBrowserFrame->m_wndBrowserView.LoadHomePage();
if(pBrowserFrame) {

pBrowserFrame->m_wndBrowserView.OpenURL("http://www.google.co.in";);
//Sleep here for sometime to wait for document to load
nsCOMPtr doc;
pBrowserFrame->GetBrowserImpl()->GetDOM(doc);
nsIDOMNode* mEndParent = (nsIDOMNode*)doc;

nsCOMPtr children;
nsresult nres = 
mEndParent->GetChildNodes(getter_AddRefs(children));
}
}

In the last line, the exe crashes stating Access Code Violation.

Please tell what's wrong with this code?

Many thanks,
Vijay


Can you verify that this line:

pBrowserFrame->GetBrowserImpl()->GetDOM(doc);

is actually getting the nsIDOMDocument?  Also, if you are successfully 
getting the nsIDOMDocument, can you verify this this line:


nsIDOMNode* mEndParent = (nsIDOMNode*)doc;

is also getting something and not just failing?
