此程序是用WTL+ATL编写，开发环境为VS2008。data.dll模拟访问驱动程序获得数据序列（本例中设计为正弦曲线数据，详见DataInfo.h），PC.exe用于模拟生产者消费者模型：一个生产者线程调用DLL获得数据，一个消费者线程获得数据并更新显示数据，主界面线程显示该数据，画出动态数据演变的曲线图。-This procedure is used WTL+ ATL development, development environment for the VS2008. visit da

通过c语言程序，让cpu画正弦曲线，可以使用资源管理器查看。-Through the C language program, so that CPU draw sine curve, you can use the resource manager to view.

一条ＳＩＮ曲线,正弦曲线,通过改变参数的设顶,可以改变曲线的形状-A sine curve, the sine curve, by changing the parameters of the cap, can change the shape of the curve

圆沿正弦曲线运动,并且圆会大小变化！的VC++API程序！,(Circular movement along a sine curve, and circle size will change!)
