 * 
 * *****************  Version 17  *****************
 * User: Kirk Stowell Date: 10/30/99   Time: 6:01p

 * *****************  Version 16  *****************
 * User: Kirk Stowell Date: 10/30/99   Time: 2:24p
 * Updated in $/CodeJock/Include
 * Added COLORREF members to class to eliminate continuous calls to
 * GetSysColor(...). Overrode OnSysColorChange() to re-initialize COLORREF
 * variables. 
 * 
 * *****************  Version 15  *****************
 * User: Kirk Stowell Date: 10/26/99   Time: 10:39p
 * Updated in $/CodeJock/Include
 * Made class methods virtual for inheritance purposes.
 * 
 * *****************  Version 14  *****************
 * User: Kirk Stowell Date: 8/31/99    Time: 1:11a
 * Updated in $/CodeJockey/Include
 * Updated copyright and contact information.

 * 
 * *****************  Version 10  *****************
 * User: Kirk Stowell Date: 7/18/99    Time: 10:17p
 * Updated in $/CodeJockey/Include
 * Cleaned up inline functions, and import/export macro so that class will
 * be imported when linked to, and exported at compile time.
 * 
 * *****************  Version 9  *****************
 * User: Kirk Stowell Date: 5/17/99    Time: 9:24p
 * Updated in $/CodeJockey/Include
 * Gilberto Botaro [seafox@techno.com.br] - Added code for auto
 * completion.
 * 
 * *****************  Version 8  *****************
 * User: Kirk Stowell Date: 5/03/99    Time: 10:44p
 * Updated in $/CodeJockey/Include
 * Fixed code ommisions.
 * 
 * *****************  Version 7  *****************
 * User: Kirk Stowell Date: 5/03/99    Time: 8:42p
 * Updated in $/CodeJockey/Include
 * Danilo Lax [Danilo_Lax@www2.alpeng.com] - The control is painted flat
 * when the mouse leaves the box, even if the control has the focus, now
 * checking for the focus in OnTimer(.
 * 
 * Removed, unhandled msgs are processed by
 * CComboBox::PreTranslateMessage(pMsg). Used reflected msgs
 * BN_GETFOCUS/CBN_KILLFOCUS instead of WM_GETFOCUS/WM_KILLFOCUS.
 * 
 * ::GetFocus() doesn't return CFlatComboBox::m_hWnd, even if the control
 * has the focus (don't know why, maybe ::GetFocus() only returns the
 * handle to the EditField part of the ComboBox), used flag m_bHasFocus
 * instead.
 * 
 * *****************  Version 6  *****************
 * User: Kirk Stowell Date: 4/03/99    Time: 4:26p
 * Updated in $/CodeJockey/Include
 * Added comments and cleaned up code.
 * 
 * *****************  Version 5  *****************
 * User: Kirk Stowell Date: 1/22/99    Time: 4:26p
 * Updated in $/CodeJockey/Include
 * Fixed accelerator problem reported by YOSH YAMASHITA
 * (yosh@muj.biglobe.ne.jp) with Matt Weagle's solution of overloading
 * PreTranslateMessage().
 * 
 * *****************  Version 4  *****************
 * User: Kirk Stowell Date: 1/02/99    Time: 4:25p
 * Updated in $/CodeJockey/Include
 * Renamed class from CJComboBox to CCJFlatComboBox, changed DRAWSTATE to
 * enum, removed method Offset(), and replaced with a direct call to
 * ::GetSystemMetrics().
 * 
 * *****************  Version 3  *****************
 * User: Kirk Stowell Date: 11/02/98   Time: 4:24p
 * Updated in $/CodeJockey/Include
 * Added OnSetFocus(), OnKillFocus() and modified OnPaint() so the control
 * remains beveled until it actually looses focus - (Vachik
 * Hovhannissian).
 * 
 * *****************  Version 2  *****************
 * User: Kirk Stowell Date: 10/05/98   Time: 4:24p
 * Updated in $/CodeJockey/Include
 * Fixed offset bug to use GetSystemMetrics(), instead of hard coded
 * values -
 * Todd Brannam (tbrannam@msn.com).
 *
