WTL Multi-Thread

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,

I use codejock Suite Pro in a program written in WTL Multi-Thread.
In the main thread of the application, everything works well, but I use threads in which I would use the TaskDialog, but I cannot instantiate _DTaskDialog, I get an error: E_NOINTERFACE.

Any ideas?

My Sample:

DWORD MyThread ( ... )
{
      HRESULT hr = CoInitializeEx ( NULL, COINIT_APARTMENTTHREADED ) ;

      OLECHAR szGuid[128] ;
      StringFromGUID2 ( __uuidof ( XtremeSuiteControls::TaskDialog ), ( LPOLESTR ) szGuid, sizeof ( szGuid ) ) ;

      CRect rcDefault ;

      // ------ Create Task Dialog -----
      CComPtr<IUnknown> spControl ;
      CAxWindow AxTaskDialog ;
      AxTaskDialog.Create ( hWnd, &rcDefault, szGuid, WS_CHILD | WS_VISIBLE  ) ;

      hr = AxTaskDialog.QueryControl ( &spControl ) ;
      CComPtr<XtremeSuiteControls::_DTaskDialog> pITaskDialog ;
      hr = spControl->QueryInterface ( __uuidof ( XtremeSuiteControls::_DTaskDialog ), ( LPVOID * ) &pITaskDialog ) ;

      // hr = E_NOINTERFACE
}

Thanks
Robert
