这两天写了一个小程序,可以定时从网上下载图片来设置为电脑的桌面。程序主要是用java实现的，采用了正则表达式来从网页文件中分析得到图片地址。因为设置图片为桌面必须使用windows api,设置图片为桌面的代码采用了C代码，使用jni(javaa本地接口)来和java程序集成。

程序获取图片的网址和时间间隔都可以设置，现在我使用的是百度的图片搜索来查找图片，每半个小时更换一次桌面，再也不用面对一成不变不变的桌面了，百度会替我查找最漂亮的图片设置为桌面。-Two days to write a small program that can regularly download pictures from the Internet to set the computer desktop. Process is mainly achieved with java, using regular expressions to analyze the document from the website get the picture address. Set picture as desktop must use windows api, set the picture as desktop code using C code, use the jni (javaa local interfaces) to integrate and java program. Procedures for obtaining images of the site and time interval can be set, and now I' m using Baidu' s image search to find the picture, each half-hour to replace a desktop, and no longer have to change the face of static desktop, and Baidu will for me to find The most beautiful pictures set to your desktop.
