Periodically changing desktop wallpaper using Ruby

Here is small ruby script that picks up a random image from a given folder and sets it as the desktop wallpaper.

   1: require 'Win32API'

   2:  

   3: SPI_SETDESKWALLPAPER = 20

   4: SPIF_SENDCHANGE = 0x2

   5: SOURCE_FOLDER = "C:\\Users\\Gaurav\\Pictures\\Best\\"

   6:  

   7: files = Dir.entries(SOURCE_FOLDER) - [".", ".."]

   8: file = files[rand(files.length)]

   9:  

  10: systemParametersInfo = Win32API.new("user32","SystemParametersInfo",["I", "I", "P", "I"],"I")

  11: p systemParametersInfo.call(SPI_SETDESKWALLPAPER, 1, SOURCE_FOLDER + file, SPIF_SENDCHANGE)

The constant SOURCE_FOLDER can be changed to point at the folder which contain all your wallpaper and the script then randomly chooses a wallpaper from the collection.

You can also set your task scheduler to run this script automatically after a fixed interval so that your desktop wallpaper keeps changing.

Here is the pastie.
