in a html page, i need using my two activex control. And one activex control
need use another control as param, the html code like this:

<object declare="declare" id="obj1" classid="CLSID:xxx-..."></object>

<object id="obj2" classid="CLSID:yyy-...">
    <param name="bindedobject" value="obj1" valuetype="object">
    
</object>

the two inteface are "dual".
[
  object,
  uuid(xxx-xx-xx),
  dual,
  helpstring("IObject2 Interface"),
  pointer_default(unique)
]
interface IMyObject2 {
....
[propget, id(35), helpstring("binded object"), bindable] HRESULT
bindedobject([out, retval] IDispatch** pVal);
[propput, id(35), helpstring("binded object"), bindable] HRESULT
bindedobject([in] IDispatch* newVal);
}

CMyObject2:
BEGIN_PROP_MAP(CMyObject2)
....
PROP_ENTRY("bindedobject", 35, NULL)
....
END_PROP_MAP()

HRESULT CMyObject2::put_bindedobject(IDispatch* newVal) {
  //this methos will not been called......... why?
}

what's problem? The other parameters are all right(such as BSTR, int, etc),
how to pass the object parameter?

Thx.
