Re: Firefox 4 b5 & b6 : accNavigate(NAVRELATION_EMBEDS) returns 0x80070057?

Hi David,

> Are you 100% sure the "good" computer has FF4 beta6?
Yes, I do. The look & feel is different and I have checked the
classes: the top level window is MozillaWindowClass (in FF3 it was
MozillaUIWindowClass).
But on my 2 computers, both FF3 & FF4 are installed.
It perfectly works on my "good" computer with both FF3 & FF4.
On my bad computer, it only works with FF3.

My problem is to get a IAccessible pointer, in order ton parse the
HTML and get informations about the content with the
ISimpleDOMDocument interface. Here is a peace of code:
		hr=AccessibleObjectFromWindow(w,(DWORD)OBJID_CLIENT,IID_IAccessible,
(void**)&pAccessible);
		if (FAILED(hr)) ...

		VARIANT vtStart,vtResult;
		vtStart.vt=VT_I4;
		vtStart.lVal=CHILDID_SELF;
		hr=pAccessible->accNavigate(0x1009,vtStart,&vtResult); //
NAVRELATION_EMBEDS = 0x1009
		if (FAILED(hr)) ...
		if (vtResult.vt!=VT_DISPATCH)...
		pIDispatch=(IDispatch*)vtResult.lVal;
		if (pIDispatch==NULL)...

		hr =pIDispatch->QueryInterface(IID_IServiceProvider, (void**)
&pServiceProvider);
		if (FAILED(hr))...
		hr =pServiceProvider->QueryService(refguid,IID_ISimpleDOMDocument,
(void**) &pSimpleDOMDocument);
		if (FAILED(hr))...

But please have a look at screen captures here: http://www.swsso.fr/dev/firefox
(I used the Microsoft Inspect32 tool.)
- FF4-OK-topwindow.PNG : the yellow rectangle is on the top level
window -> OK
- FF4-OK-window.PNG : the yellow rectangle is on a HTLM element -> OK
- FF4-BAD-topwindow.PNG : the yellow rectangle is on the top level
window -> OK
- FF4-BAD-window.PNG : it is impossible to set the yellow rectangle on
a HTLM element -> NOT OK: Nothing can be explored inside the yellow
hilighted element!

Perhaps a conflict between FF3 & FF4? I will try to remove FF3 and FF4
before re-installing FF4.
