This is a simple program and all it does is fiddle with the registry and set the value of the desktop background to be the bmp file that you supply in the function. There are other things you can do with the windows registry, this is just one of the easy things that demonstrates how it all works.


import win32api, win32con, win32gui

def setBackground(image):
    key = win32api.RegOpenKeyEx(win32con.HKEY_CURRENT_USER,"Control Panel\\Desktop",0,win32con.KEY_SET_VALUE)
    win32api.RegSetValueEx(key, "WallpaperStyle", 0, win32con.REG_SZ,"0")
    win32api.RegSetValueEx(key, "TileWallpaper", 0, win32con.REG_SZ,"0")
    win32gui.SystemParametersInfo(win32con.SPI_SETDESKWALLPAPER, image, 1+2)
