To deal something like this, all you had to was put a break point at
the beginning of the function. Since you did not have a message map
entry, it would have never been called. And that would have pointed you
in the right direction.

Ajay's last post alerted me to something. I simply forgot to include the
ON_NOTIFY_EX(TTN_NEEDTEXT, 0, OnToolTipNeedText) in my message map. So the
OnToolTipNotify wasn't being called. Thanks for your help.

Here is my OnToolTipNotify source. In it I do some hittesting and then I try

Thanks.

BOOL CNetQuaSimView::OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT *

{
      BOOL bHandledNotify = FALSE;

    CPoint CursorPos;
    VERIFY(::GetCursorPos(&CursorPos));

    CRect ClientRect;
    GetClientRect(ClientRect);

    // Make certain that the cursor is in the client rect, because the
    // mainframe also wants these messages to provide tooltips for the
    // toolbar.
    if (ClientRect.PtInRect(CursorPos))
    {
        TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;
        m_pBuildingHit = HitTest(CursorPos);
        UINT nID = pNMHDR->idFrom;

        if (m_pBuildingHit)
        {
    CString strTip;
    const CPoint& Origin = m_pBuildingHit->GetBuildingOrigin();
    strTip.Format(_T("Origin: (%d, %d)"), Origin.x, Origin.y);
    ASSERT(strTip.GetLength() < sizeof(pTTT->szText));
    ::wcscpy_s(pTTT->szText, strTip);
    m_ToolTip.SendMessage(TTM_SETTIPTEXTCOLOR, 0L);
        }
        else
        {
            pTTT->szText[0] = 0;
        }
        bHandledNotify = TRUE;
    }
    return bHandledNotify;
}

Your code is responsible for showing this text. Is OnToolTipNotify getting
called? Its OK to include the soure of that method for us to see whats going
on.

I'm simply displaying a few bitmaps in my SDI app. In OnToolTipNotify I do
some hittesting and I try to fill in my data (a CString after "Format")

into

pTTT->szText. I've also tried pTTT->lpszText. However, whenever I pass the
mouse over my bitmaps all I get is the "First Record" text. If you like I

can

include the source I am using for OnToolTipNotify.

Thanks.

My tooltip seems to work fine since it appears the way I expect it to.

However, no matter what I try the tooltip always displays "First

Record". Can

someone explain to me why this happening and how to solve it.

What tooltip is this (toolbar or on a control in a dialog)? How are you
changing it(dynamically or resource editor)?
