Cdialog - Override ESCAPE and RETURN keys

I have a dialog box and I want to prevent those two keys from closing it. I
also want to detect the ESCAPE key for another purpose (stop the animation
from playing). I tried various things after searching this forum and
visiting one of the MVPs sites.

This is what I have now:

BOOL AnimationCreationHorDLG::PreTranslateMessage(MSG* pMsg)
{
    if (pMsg->message == WM_KEYDOWN)
    {
        if (pMsg->wParam == VK_RETURN || pMsg->wParam == VK_ESCAPE)
            return FALSE;
    }

    return CDialog::PreTranslateMessage(pMsg);
}

UINT AnimationCreationHorDLG::OnGetDlgCode()
{
    // TODO: Add your message handler code here and/or call default

    return CDialog::OnGetDlgCode() | DLGC_WANTALLKEYS;
}

I put stops in the PreTranslateMessage, but it never gets there regardless
of the key I press when that dialog box has the focus. I even tried setting
one of the edit controls to "Want Return TRUE". There is no property for the
box itself for receiving messages that I can see. I have also added other
overrides with no success.

How can I get my CDialog derived class to get these keys?

Thanks.
