tooltips in a dialog

I want to show tooltips when the user has the cursor over the dialog controls, so firstly I call EnableToolTips(),
Then I call the tooltipOnNotify, for some reason it only gets into the OnToolTipNotify function for certain controls & won't get into the function when the cursor is over a check box or a static control or a radio button...., so the question is what do I have to do to get the tooltip over all controls
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTW, 0, 0xFFFF, OnToolTipNotify)
ON_NOTIFY_EX_RANGE(TTN_NEEDTEXTA, 0, 0xFFFF, OnToolTipNotify)

BOOL CDialog::OnToolTipNotify(UINT id, NMHDR *pNMHDR,LRESULT *pResult)
{

TOOLTIPTEXTA *pTTTA = (TOOLTIPTEXTA *)pNMHDR;
TOOLTIPTEXTW *pTTTW = (TOOLTIPTEXTW *)pNMHDR;
CString strTipText;
UINT nID = pNMHDR->idFrom;

if (pNMHDR->code == TTN_NEEDTEXTA && (pTTTA->uFlags & TTF_IDISHWND) ||
pNMHDR->code == TTN_NEEDTEXTW && (pTTTW->uFlags & TTF_IDISHWND))
{
// idFrom is actually the HWND of the tool
nID = ::GetDlgCtrlID((HWND)nID);
}

if (nID != 0) // will be zero on a separator
strTipText.Format("Control ID = %d", nID);

*pResult = 0;
if (pNMHDR->code == TTN_NEEDTEXTA)
{
lstrcpyn(pTTTA->szText, strTipText, sizeof(pTTTA->szText));
}else //unicode
{
_mbstowcsz(pTTTW->szText, strTipText, sizeof(pTTTW->szText));
}

return TRUE; // message was handled

}

why do not you use CToolTipCtrl. this class is much easier to integrate into your dialog code

Can you please show me sample code on how to implement it in my dialog.

Thanks
