dll 为功能实现模块，exe为测试程序，调用dll后exe进程将消失，除非用驱动级的软件才能看到该进程-dll function modules for the test procedure exe, dll called after exe process will disappear. Driver-unless the software can see the process

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
