/*
* TODO <-------------
* 1. The following extended styles need to be implemented, use will
* result in a FIXME:
* CBES_EX_NOEDITIMAGEINDENT
* CBES_EX_PATHWORDBREAKPROC
* CBES_EX_NOSIZELIMIT
* CBES_EX_CASESENSITIVE
* 2. None of the following callback items are implemented. Therefor
* no CBEN_GETDISPINFO notifies are issued. Use in either CBEM_INSERTITEM
* or CBEM_SETITEM will result in a FIXME:
* LPSTR_TEXTCALLBACK
* I_IMAGECALLBACK
* I_INDENTCALLBACK
* 3. No use is made of the iOverlay image.
* 4. Notify CBEN_DRAGBEGIN is not implemented.

/*
* ComboBoxEx control v2 (mod5)
*
* 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>
*
* 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 CBEM_DELETEITEM, CBEM_GETITEM{A|W}, CB_SETCURSEL,
* CBEM_{GET|SET}UNICODEFORMAT.
* 8. Add override for WNDPROC for the COMBO control.
* 9. Support extended style CBES_EX_NOEDITIMAGE and warn others are not
* supported.
* 10. Implement CB_FINDSTRINGEXACT in both the Combo and ComboEx window
* procs to match the items. This eliminates dup entries in the listbox.
*
* mod 4
* 1. Implemented CBN_SELCHANGE, CBN_KILLFOCUS, and CBN_SELENDOK.
* 2. Fix putting text in CBEN_ENDEDIT notifys for CBN_DROPDOWN case.
* 3. Lock image selected status to focus state of edit control if
* edit control exists. Mimics native actions.
* 4. Implemented WM_SETFOCUS in EditWndProc to track status of
* focus for 3 above.
* 5. The LBN_SELCHANGE is just for documentation purposes.
*
* mod 5
* 1. Add support for CB_GETITEMDATA to a Comboex. Returns the LPARAM
* passed during insert of item.
* 2. Remember selected item and don't issue CB_SETCURSEL unless needed.
* 3. Add initial support for WM_NCCREATE to remove unwanted window styles
* (Currently just WS_VSCROLL and WS_HSCROLL, but probably should be
* more.)
* 4. Improve some traces.
* 5. Add support for CB_SETITEMDATA sets LPARAM value from item.
*
* Test vehicals were the ControlSpy modules (rebar.exe and comboboxex.exe),
* WinRAR, and IE 4.0.
