I need to create ToolTips in DialogBox
My Dialog box contains:
1)PushButtons
2)CheckBoxes
3)ComboBoxes

I've done such thing:
1)
BOOL CMyDialogBox::OnInitDialog()
{
......
......
EnableToolTips(true)
......
}

2)
BEGIN_MESSAGE_MAP (CMyDialog, CDialog)
.....
.....
ON_NOTIFY_EX(TTN_NEEDTEXT,0,OnTTip)
END_MESSAGE_MAP()

3)
BOOL CMyDialog::OnTT(UINTidFrom,NMHDR*hdr,LRESULT *ResultNotUsed)
{
TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)hdr;
UINT nID = pTTT->hdr.idFrom;
pTTT -> lpszText = "TEST";
return(true);
}

It works for PUSH BUTTONS ONLY
But it dosen't work for comboboxes,lables and checkboxes.
Please help me.
Thank you.
Alex
