灰色按扭激活--可以将一些软件限制的灰色按扭激活使用,比如某些软件普通会员会限制一些功能,有这个就可以解开限制(Gray button activation- can be some of the limitations of the gray button to activate the software to use, such as some software will limit some features of ordinary members, have this limit can be solved)

批量读写配置文件 　本例程使用复制组件，复制所需要的窗口组件，并且配合组件的 标记、取标记组件、取事件组件，让组件互相关联互动。这样做的好 处是：设计时窗口组件很少，节省设计时间，节约空间，便于代码的 后期升级维护。(Read and write configuration files in batches)
