My app isn't unicode, the compiler maps to TTN_NEEDTEXTA.

Thanks, Drew. I have all that in my code as the msdn examples clearly
describe. As I stated before, I'm getting the notification for my OK and
Cancel buttons.

However, no notification takes place for my edit controls. Is there
something special about edit control they don't work with tooltips in this
way?

Thanks

You need this in your message map:

BEGIN_MESSAGE_MAP(CGeometryPage, CPropertyPage)
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, GetToolTip)
END_MESSAGE_MAP()

Function implementation:

BOOL CMyDialog::GetToolTip(UINT id, NMHDR *pNMHDR, LRESULT *pResult)
{
TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;
UINT nID = pNMHDR->idFrom;
if (pTTT->uFlags & TTF_IDISHWND)
{
  // idFrom is actually the HWND of the tool
  nID = ::GetDlgCtrlID((HWND)nID);
  switch(nID){
   case IDC_MY_EDIT:
    // Use whatever method you wish to get the string into pTTT->szText
    strcpy(pTTT->szText, "My tooltip");
    pTTT->hinst = NULL;
    return(TRUE);
   break;
  }
}

return(FALSE);
}

Hi, I'm using VC++ in VStudio 2005. Inside my dialog of CDialog base
type,
I'm dynamically (programmatically) creating several child edit controls of
my
own type (CSendchk) based on CEdit. These edit controls look and function
perfectly within the parent dialog.

I would like to display a tooltip when mouse hovers over any of those edit
controls. So, as the help reference guide suggests, I added a call to
EnableToolTips(TRUE) inside my InitDialog() method and hook the
notification
with my override CSendchk:OnToolTipNotify().

As expected, I do receive the notification for my OK and Cancel buttons,
so
the tooltip notification system apparently works. However, I receive none
for any of my edit controls.

Anyone know why?

My edit control creation code is:

for ( int iCnt=0; i<10; iCnt++ )
{
  (control positioning code here)

  m_pedtCells[iCnt] = new CEditchk();

  m_pedtCells[iCnt]->Create(WS_CHILD|WS_TABSTOP|WS_VISIBLE,
  r, this, iCnt+1 );
}

Thanks for any help

Try handling both, TTN_NEEDTEXTW and TTN_NEEDTEXTA.
