// TaskbarNotifier.cpp : implementation file
// By John O'Byrne
// 11 August 2002: - Timer precision is now determined automatically
//		   Complete change in the way the popup is showing (thanks to this,now the popup can be always on top, it shows even while watching a movie)
//		   The popup doesn't steal the focus anymore (by replacing ShowWindow(SW_SHOW) by ShowWindow(SW_SHOWNOACTIVATE))
//		   Thanks to Daniel Lohmann, update in the way the taskbar pos is determined (more flexible now)
// 17 July 2002: - Another big Change in the method for determining the pos of the taskbar (using the SHAppBarMessage function)
// 16 July 2002: - Thanks to the help of Daniel Lohmann, the Show Function timings work perfectly now ;)
// 15 July 2002: - Change in the method for determining the pos of the taskbar
//		 (now handles the presence of quick launch or any other bar).
//		 Remove the Handlers for WM_CREATE and WM_DESTROY
//		 SetSkin is now called SetBitmap
// 14 July 2002: - Changed the GenerateRegion func by a new one (to correct a win98 bug)
// kei-kun modifications:
// 30 October  2002: - Added event type management (TBN_*) for eMule project
// 04 November 2002: - added skin support via .ini file
