    The 'H' preceeding both meand Handle......

    HWND - Handle to window...this is your identifier for each window (and therefore control) created......

    HDC - Handle to device contect....a device context is an internal structure that hold information on how simple graphics are displayed on an output (pens, brushes, fonts....)...this output can be a screen, printer, plotter etc

    How to use them fills chapters in books........so I cant give you a comprehensive example.......

    If you dont want a book, try some tutorials (do a board and try www.sunlightd.com and http://www.foosyerdoos.fsnet.co.uk for starters)...then look at MSDN
