Changeing the wallpaper thru code

I am rather new to programing.  I want to write a small app that when run, copies a file to the windows dir then changes the display properties to display my wallpaper.  How can I do this with code??  And with no user interaction?  I cant seem to figure out what microsoft calls it.  Please be specific in your answer so that I can understand it.  Thx

1.  Declaration
          Const SPI_SETDESKWALLPAPER = 20
          Const SPIF_UPDATEINIFILE = &H1
          Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Long, ByVal uParam As Long,
          ByVal lpvParam As Any, ByVal fuWinIni As Long) As Long

2. Code
          ' Put th picture c:\windows\setup.bmp as wallpaper
          Call SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, "c:\windows\setup.bmp", SPIF_UPDATEINIFILE)

 ' get rid of Wall Paper        
          Call SystemParametersInfo(SPI_SETDESKWALLPAPER, 0, "", SPIF_UPDATEINIFILE)

It Works!  How can I have it copy a file to the windows dir?(so that I have access to it) FOR EXAMPLE:  If I put a picture in a "picture box" it dosent have to have the picture go with it to be displayed right? it is part of the exe??  how can I copy it if it was hidden on the form to the windows directory?
Do I have to use a setup program or is there a more discrete way?  I want to have some fun with this  :-)

Im sorry one more thing. Since I can change the wallpaper can I change the tile property to turn it on and off ? or the stretch property?  Guess thats two :-)
