Thanks!!!

You are mixing Qt and MFC. Are you sure???

Try using QWidget::winId to extract Windows Native Handle of the Widget

Thank you very much!
But you can give me an example of it?

Sorry but I don't know MFC.

You can do CWnd *wnd = CWnd::FromHandle(QtWnd->winId) but note that this only creates a temporary CWnd object and so should not be stored for later use.

This ok:

Code:

---

void Myclass::CreateTaskbarNotifier()
{
  CTaskbarNotifier pTaskbarItem;
  afxCurrentInstanceHandle = qWinAppInst();
  CWnd *pWnd;
  pWnd = AfxGetApp()->GetMainWnd();
  pTaskbarItem.Create(pWnd);
}
 
 
int CTaskbarNotifier::Create(CWnd *pWndParent)
{
	m_pWndParent = pWndParent;
	CString strWndClass = AfxRegisterWndClass(0, AfxGetApp()->LoadStandardCursor(IDC_ARROW), GetSysColorBrush(COLOR_WINDOW), NULL);
	return CreateEx(WS_EX_TOOLWINDOW, strWndClass, NULL, WS_POPUP, 0, 0, 0, 0, pWndParent->m_hWnd, NULL);
}
