Well, you can't pass that via IPersistPropertyBag. Instead,
pass the name you assigned to your other control and have
your object locate it on the page. Note it might not be
available yet when your property is assigned.

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.
