/*
* ComboBoxEx control v2 (mod3)
*
* Copyright 1998, 1999 Eric Kohl
*
* NOTES
* This is just a dummy control. An author is needed! Any volunteers?
* I will only improve this control once in a while.
* Eric <ekohl@abo.rhein-zeitung.de>
*
* TODO:
* - All messages.
* - All notifications.
*
* FIXME:
* - should include "combo.h"
* Changes Guy Albertelli <galberte@neo.lrun.com>
* v1 Implemented messages: CB_SETITEMHEIGHT, WM_WINDOWPOSCHANGING,
* WM_DRAWITEM, and WM_MEASUREITEM. Fixed WM_CREATE. Fixed height
* of window rect reported fixing rebar control.
* v2
* 1. Rewrite of WM_Create for own created EDIT control. Also try to
* generate message sequence similar to native DLL.
* 2. Handle case where CBEM_SETITEM is called to display data in EDIT
* Control.
* 3. Add override for WNDPROC for the EDIT control (reqed for VK_RETURN).
* 4. Dump input data for things using COMBOBOXEXITEM{A|W}.
* 5. Handle positioning EDIT control based on whether icon present.
* 6. Make InsertItemA use InsertItemW, and store all data in ..W form.
* 7. Implement CB_SETCURSEL.
* 8. Add override for WNDPROC for the COMBO control.
*
* Test vehicals were the ControlSpy modules (rebar.exe and comboboxex.exe),
* and IE 4.0.
*
