I really thank your help Gambit, it was very useful.
And yes, I need more practice with these interfaces, but in C++ it seems so 
complicated... we can see it just viewing the
translation to C++ of the really simple code in Delphi... why it's so 
different? MSDN design its interfaces thinking in Object Pascal?
I will work around your code and MSDN to reach the a version of the 
"HTMLRealLiveSource" (at least I will try to do it).

thanks !
enrique.

PD: I have a basic question, because I use it but I don't know what I'm 
doing at really...
QueryInterface is like a typecasting?
I mean...

In delhpi we can do this:
//--------------
element:IHTMLElement;
(...)
childrenElements: IHTMLElementCollection;
childrenElements:= element.children as IHTMLElementCollection;
//-----------------
***********************************
But in C++ this doesn't work:
//--------------
IHTMLElement element;
(...)
IHTMLElementCollection childrenElements;
childrenElements = (IHTMLElementCollection)element.children;
//--------------
***********************************
neither:
//--------------
IHTMLElement *element;
(...)
IHTMLElementCollection *childrenElements;
childrenElements = dynamic_cast<IHTMLElementCollection*>(element->children);
//--------------
***********************************
as a matter of fact we must do something like this:
//--------------
IHTMLElement *element;
(...)
TComInterface<IDispatch> disp;
element->get_children(&disp);
if( disp )
{
  TComInterface<IHTMLElementCollection> childrenElements;
  disp->QueryInterface(IID_IHTMLElementCollection, 
(LPVOID*)&childrenElements);
//--------------
************************************
it's really much more abstract (to me) to understand it...
