1、一个原创地仪表控件路过世纪飞扬的网站发现好些个仪表控件，可惜都要付费，这对于很多用户来说不得不说是一件憾事。最近两天导师项目不忙，就抽空做了一个仪表控件，是对照别人的仪表外观做的，在此公布出来大家讨论讨论，最好大家都写些免费的控件放在网上，好资源共享。如果有兄弟觉得好用的话，请在使用处留下俺的名号，这就够给我面子了。1效果图2CMeter 类的使用方法（1） Meter.cpp 和 Meter.h 以及 MemDC.h 加入到你的工程中。 （2） 在你的工程中放入一个图片框控件，并通过类向导声明一个 CStatic 类的对象，例如叫 m_myMeter。 （3） 用 CMeter 替换 m_m
