Hi. I tested with InitCommonControls and i am unable to click through the

tooltip, the OK button recieves the command to close?

Yes, it does.

This is the manifest file I embedded in resources:

---- Start of Manifest

The platform is Windows XP SP2 with VC++6 SP6.

This is the code (I encapsulated the tool-tip test in TestToolTip
method, and call it from OnOK handler):

<CODE>
void CToolTipTestDlg::ToolTipTest()
{
    TOOLINFO TI;
    static long nIndex = 0;
    CRect rectTemp;
    CFont* pfont;
    CWnd* pwndOK;

    CString text;
    text.Format( _T("nIndex = %d"), nIndex );

    PREPARE_STRUCT( TI )
    TI.lpszText = const_cast< LPTSTR >( static_cast< LPCTSTR >( text )
);

    if(IsWindow(m_wndToolTip) == FALSE)
    {
        m_wndToolTip.Create(this, TTS_ALWAYSTIP | TTS_NOPREFIX);
        m_wndToolTip.SetMaxTipWidth(SHRT_MAX);

        //Add tool
        TI.uFlags = TTF_TRACK | TTF_TRANSPARENT;

        m_wndToolTip.SendMessage(TTM_ADDTOOL, 0, (LPARAM)&TI);
    }
    else
    {
        //Modify the text of the tooltip.
        m_wndToolTip.SendMessage(TTM_UPDATETIPTEXT, 0, (LPARAM)&TI);
    }

    //Take over the font from the dialog.
    pfont = GetFont();
    if(pfont != NULL)
    {
        m_wndToolTip.SetFont(pfont);
    }

    //Set the position of the tooltip.
    pwndOK = GetDlgItem(IDOK);
    pwndOK->GetWindowRect(&rectTemp);
    m_wndToolTip.SendMessage(TTM_TRACKPOSITION,
    0, (LPARAM)MAKELONG(rectTemp.left, rectTemp.top));

    //Show tooltip
    PREPARE_STRUCT( TI )
    m_wndToolTip.SendMessage(TTM_TRACKACTIVATE, TRUE, (LPARAM)&TI);

    //Increment the static index
    nIndex++;
}

void CToolTipTestDlg::OnOK()
{
    ToolTipTest();
    CDialog::OnOK();
}
</CODE>

If you give me a valid e-mail address, I can send you a copy of the
VC++ project.
