在工业控制软件中经常要显示测量数据，如果在在界面上单纯显示一些数字会显得很单调，如果能在软件中添加色泽艳丽的控件，就一定会为你的软件增色不少，让人有爽心悦目的感觉。在此就介绍一款这样的仪表控件。 -in industrial control software often measured data to show that, if the interface simple figures show was very dull, and if the software can add color sensational control, we would be the software for your occasion gives Shuangxin pleasant feeling. In one such briefing on the dashboard controls.

COM组件，也就是组件对象模型（Component Object Model），它本身是一种与具体平台无关的标准，支持Automation功能。VC++的ATL（活动模板库）提供了一种简便而灵活的方法用来创建COM组件对象，因为所占用的空间很小，所以被编译的控件也很小。因此我们选择ATL来设计和开发一个COM组件，该组件在窗口中绘制一个双钟摆并且可以通过修改函数参数来重绘组件，使之产生动态效-COM, which is Component Object Model (Component Object Model), which itself is a specific platform-independent standards that support Automation function. VC ATL (activity Template Library) provides a simple and flexible way to create COM object, because the space occupied by small, the controls are built very small. ATL therefore we choose to design and develop a COM component, the component in the window drawing a double pendulum and may amend function parameters to repaint components, thus producing dynamic effect
