Previously published "Using Java to set the Bing daily wallpaper to Win7 wallpaper", read the comments and decided to make this idea on the Win7.

In fact, the implementation on the Win7 and on the implementation of Ubuntu is not very big difference, the previous parsing XML and download the image is the same, the difference is to set the wallpaper behind.

Win7 the code to set up the wallpaper is a bit cumbersome and not as good as the Linux direct call command. Later, when the boot entry was set, it was found that the sequence of running the jar file was preceded by the start of the network service, so I used a do...while to solve the problem (see the code for the main function).

Compiling this program requires the use of the Jna.jar package and the Jna-platform.jar package.

It is recommended to package its compilation into an executable jar file, then click on the Start menu----" All Programs "-----" Start "Right-click" Open "to drag the jar file into the open folder, so that the wallpaper will be automatically switched on every day ~ ~
