I try to add tooltips for my controls on a dialog application.

in OnInitDialog(), I add :

EnableToolTips(TRUE);

Then I add ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNotify) in message
map:


BEGIN_MESSAGE_MAP(CMFC_ZoomDlg, CDialog)
....
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNotify)
....
END_MESSAGE_MAP()

and:

BOOL CMFC_TestDlg::OnToolTipNotify( UINT unId, NMHDR *pstNMHDR,
LRESULT *pstResult )
{
UNUSED_ALWAYS (pstResult);
UNUSED_ALWAYS (unId);
TOOLTIPTEXT* pstTTT = (TOOLTIPTEXT * )pstNMHDR;
UINT nID = pstNMHDR->idFrom;
if ((pstTTT->uFlags & TTF_IDISHWND))
{
// idFrom is actually the HWND of the tool
nID = ::GetDlgCtrlID((HWND)nID);

pstTTT->lpszText = _T("Hello");
pstTTT->hinst = AfxGetResourceHandle();
return(TRUE);
}
return (FALSE);
}

On my dialog, I have some EditBox, RadioButton, Button ComboBox. But
some control show tooltips and others not. Could someone tell me why?

I find the controls with no tooltips are controls with tab order
bigger than the Group control tab order. How to set tooltips with any
tab order.

Your BEGIN_MESSAGE_MAP specifies CMFC_ZoomDlg where as your
OnToolTipNotify is defined for CMFC_TestDlg. I can't tell if you have
some inheritance going on here, but when I do these they are normally
for the same class.

Sorry, both place should be CMFC_TestDlg.

Do you have:

if (m_pToolTip)
m_pToolTip->RelayEvent(pMsg);

IN:
CMFC_TestDlg::PreTranslateMessage(MSG* pMsg)

?
