IE 9 failed to fire DISPID_ONQUIT event
The following code is for a toolbar to revceive DWebBrowserEvents2 events from Internet Explorer. Running on IE 8 and 7, the toolbar can catch both DISPID_DOCUMENTCOMPLETE and DISPID_ONQUIT events. On IE 9, the tooblar receives only DISPID_DOCUMENTCOMPLETE, the message box "Document load complete" will show when I open IE. But the toolbar can not receive DISPID_ONQUIT, the message box for "IE CLOSE event" never appears when I close IE 9, it looks like that IE 9 does not fire DISPID_ONQUIT event. Does IE 9 forget to fire this event? Thanks for any help!
Code:
STDMETHODIMP CMyIEToolBar::Invoke(DISPID dispidMember, REFIID riid, LCID lcid, WORD wFlags,
DISPPARAMS* pDispParams, VARIANT* pvarResult,
EXCEPINFO* pExcepInfo, UINT* puArgErr)
{
HRESULT lResult = S_OK;
if (!pDispParams)
return E_INVALIDARG;
switch (dispidMember)
{
case DISPID_DOCUMENTCOMPLETE:
MessageBox(NULL, _T("Document load complete"), _T("DOCUMENT COMPLETE"),MB_OK);
break;
case DISPID_ONQUIT:
//case DISPID_QUIT:
MessageBox(NULL, _T("IE CLOSE event"), _T("IE close"),MB_OK);
ManageConnection(Unadvise);
break;
default:
break;
}
return lResult;
}
