Thanks for all your help. The following code seems to work fine:
UINT CMemoEdit::OnGetDlgCode()
{
    UINT rtn;

    // Don't let the base class (CEdit) see the message
    // rtn=CEdit::OnGetDlgCode();

    // Create the CEdit basic return (flags)
    rtn=DLGC_WANTARROWS|DLGC_WANTCHARS|DLGC_HASSETSEL|DLGC_WANTALLKEYS;

    // Add the tab flag
    rtn |= DLGC_WANTTAB;

    return rtn;
}

The reference article wanted the message checked for tab and backspace keys
but that doesn't seen necessary.
Any comments???

Thanks again, Neil

I added the following message handler to the control CMemoEdit (derived
from
CEdit). The method does get control and the DLGC_WANTTAB flag is "ORed" in
properly but the parent CDialog is still getting the tab keystroke. It
moves
the focus from contol to contol until it's back in the CEdit control it
started from. Is there something else that is needed here???

Thanks, Neil

UINT CMemoEdit::OnGetDlgCode()
{
UINT rtn;
rtn=CEdit::OnGetDlgCode();
rtn |= DLGC_WANTTAB;
return rtn;
}

The trick is to not let the edit class WindowProc even see the message if
the (LPMSG)(LPARAM) is WM_KEYDOWN/VK_TAB...
