获得系统内存，并以圆饼图表现百分比，很早的程序了，用在现在的大硬盘电脑上可能有错误，不过也很好修正，无非是函数的调用问题，程序核心要表现的并不是如何获得Windows的内存使用量，而是如何将数据与圆饼图捆绑，从而生成百分比图。如上图所示。-Access to system memory, and pie charts show the percentage of the program early, and large hard drives used in computers today may be wrong, but is also very good amendment, the issue is nothing more than call the function, the program is not core to the performance of How to get the memory usage of Windows, but rather how the data is bundled with the pie chart to generate a percentage figure. As shown above.
