Hello,
I'm embedding the Mozilla ActiveX Control in a .Net application, which
is working very well so far. One limitation is the ability to retrieve
an object that implements MSHTML.IHtmlWindow (or similar) from a frame
element. At present, I can get the frame's element (the "IFRAME"
element) which implements IHtmlElement, but I need it to also
implement IHtmlFrameElement (or similar) to be able to get the
contents of that frame.
I'd like to have a go at implementing MSHTML's IHtmlDocument2's
get_frames method in embedding/browser/activex/src/control/
IEHtmlDocument.cpp.
I've found the skeleton method:
HRESULT STDMETHODCALLTYPE
CIEHtmlDocument::get_frames(IHTMLFramesCollection2 __RPC_FAR
*__RPC_FAR *p)
{
*p = NULL;
return E_NOTIMPL;
}
Does anyone have any advice about where to begin? I'm new to XPCOM
(and C++ for that matter) I've found various "GetFrames" methods
within Gecko's source, some of which return a collection of DOMWindow
objects, which seems promising. I'm hoping the existing
nsIDOMHTMLDocument instance field within IEHtmlDocument will be enough
to get access to a GetFrames method.
Does this sound like the right way to go about it? If there's an
easier way to get frames support in the ActiveX control, I'd be keen
to hear it!
Thanks,
Matthew
