// //////////////////////////////////////////////////////////////////////////

// Properties:
//	NO	Abstract class (does not have any objects)
//	YES	Derived from CComboBox

//	YES	Is a Cwnd.                     
//	YES	Two stage creation (constructor & Create())
//	YES	Has a message map
//	YES	Needs a resource (template)

//	NO	Persistent objects (saveable on disk)      
//	NO	Uses exceptions

// //////////////////////////////////////////////////////////////////////////

// Desciption :         

// Remark:

// Prerequisites (necessary conditions):
//	This control needs idle processing to update its GUI (enable/disabme buttons etc)
//	It uses the WM_IDLEUPDATECMDUI message for this.
//	This message is send during on idle to all the children of the main frame

//	This kind of idle processing is not available from a message box
//	Here you can use the not documented WM_KICKIDLE message of the dialog
//  to explicly call the OnIdle function of this control
//		#include <afxpriv.h>	// for WM_KICKIDLE
//		ON_MESSAGE(WM_KICKIDLE, OnKickIdle)
//		LRESULT CMyDlg::OnKickIdle(WPARAM wParam, LPARAM lParam)
//			{
//			ASSERT(wParam == MSGF_DIALOGBOX);
//			LONG lIdleCount = lParam;
//			BOOL bContinueIdle = TRUE;
//		
//			// Update the edit list
//			m_wndEditList.OnIdle();
//		
//			return bContinueIdle;
//			}

// This control needs the toolbar resource with the ID IDR_OX_HISTORY_COMBO_TOOLS
//	It contains the buttons ID_OX_HISTORY_COMBO_NEW, ID_OX_HISTORY_COMBO_DELETE,
//	ID_OX_HISTORY_COMBO_BROWSE, ID_OX_HISTORY_COMBO_RESERVED_1 and ID_OX_HISTORY_COMBO_RESERVED_2
//	The name of these last two ID may change in the future
//	So the first 5 buttons are fixed, but you can add your own buttons behind them
