我最近刚刚写出了能运行的代码，但是MFC的代码分布太分散，除了在CViewcpp里面，其他的源文件里也有，没办法在这里全贴出来。如果你想要全部文件的话，可以给我留个邮箱或者聊天账号之类的****。

我这里只能给你简单说一说我的思路。把客户区分成逻辑的两个区域，在左侧区域调用pDC->Ellipse()画出圆形，求出圆心坐标和半径，然后用三角函数乘以半径来定出三根表针的长度，画表针的时候定义三个不同的CPen对象,像素和RGB颜色设置不同就可以了。再调用pDC->MoveTo()和pDC->LineTo()把它们画出来。至于你说的文字和电子表上的示数，可以用pDC->TextOut（）来实现。注意给它指定恰当的位置。

这里是我运行的结果。不知道是否符合你的要求。
