Getitng the browser instance from ActiveQt

Hello,

I have created an active X control using Active Qt framework which is loaded inside an IE browser. Now i want to retrieve the URL from the browser.

My active X code will look something like this

Code:

---

class ActiveX : public QObject, public QAxBindable
{
...
}
 
class ObjectSafetyImpl : public QAxAggregated, 
						 public IObjectSafety
{
public:
    ObjectSafetyImpl() {}
 
    long queryInterface( const QUuid &iid, void **iface )
    {
	*iface = 0;
	if ( iid == IID_IObjectSafety )
	    *iface = (IObjectSafety*)this;
	else
	    return E_NOINTERFACE;
 
	AddRef();
	return S_OK;
    }
 
    QAXAGG_IUNKNOWN;
 
    HRESULT WINAPI GetInterfaceSafetyOptions( REFIID riid, DWORD *pdwSupportedOptions, DWORD *pdwEnabledOptions )
    {
	*pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA | INTERFACESAFE_FOR_UNTRUSTED_CALLER;
	*pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA | INTERFACESAFE_FOR_UNTRUSTED_CALLER;
	return S_OK;
    }
    HRESULT WINAPI SetInterfaceSafetyOptions( REFIID riid, DWORD pdwSupportedOptions, DWORD pdwEnabledOptions )
    {
	return S_OK;
    }
};
 
QAxAggregated *ActiveX::createAggregate()
{
    return new ObjectSafetyImpl();
}

---

Now it try to get the browser instance using the following piece of code

Code:

---

IWebBrowser2 *webBrowser = 0;
	clientSite()->QueryInterface(IID_IWebBrowser2, (void **)&webBrowser);
	BSTR* strHostURL = 0;
	if(webBrowser)
		webBrowser->get_LocationURL(strHostURL);

---

But the webBrowser object always turns out to be NULL. Any help???
