说明： 在网上很多SPCOMM组件下载安装后都无法显示，这个是我找了很久才找到可以用的一个，一定要先把文件夹复制到LIB文件夹下再安装才会在组件面板SYSTEM中出现一个红色的组件 (SPCOMM many of the Internet to download and install components that can not be displayed after all, this is what I look for a long time before they can find the one that must first copy the folder to folder LIB install only the components panel SYSTEM appeared in the components of a red)
