/////////////////////////////////////////////////////////////////////////////
// TrayIcon.cpp : implementation file
//
// This is a conglomeration of ideas from the MSJ "Webster" application,
// sniffing round the online docs, and from other implementations such
// as PJ Naughter's "CTrayIconifyIcon" (http://indigo.ie/~pjn/ntray.html)
// especially the "CTrayIcon::OnTrayNotification" member function.
//
// This class is a light wrapper around the windows system tray stuff. It
// adds an icon to the system tray with the specified ToolTip text and 
// callback notification value, which is sent back to the Parent window.
//
// The tray icon can be instantiated using either the constructor or by
// declaring the object and creating (and displaying) it later on in the
// program. eg.
//
//		CTrayIcon m_TrayIcon;	// Member variable of some class
//		
//		... 
//		// in some member function maybe...
//		m_TrayIcon.Create(pParentWnd, WM_MY_NOTIFY, "Click here", 
//						  hIcon, nTrayIconID);
//
// Clobbered together by Chris Maunder.
//
