看 ＭＳＤＮ吧！
第一个参数： Requested font height in tenths of a point
十分之一点（例如输入 １２０， 表示大小为 １２点）
It automatically converts the height in nPointSize to logical units using the CDC object pointed to by pDC
它自动根据ＣＤＣ将高度从 ＂点＂ 转换为逻辑单元
由此可见， 跟映射模式相关的

先得到罗辑的每个点实际的物理点个数
然后* 80
然后* 80

有一段类似代码

m_logfonttemp.lfHeight=CountHeight(m_logfonttemp.lfHeight);
font.CreateFontIndirect(&m_logfonttemp);
CFont *pFont=pDC->SelectObject(&font);//字体要和Draw中子体一杨
pDC->SetMapMode(MM_HIMETRIC);//视图映射模式
CString tempString;
CString string;
CString findstring("\n" );
CSize haha;
CSize TotalSize = CSize(0,0);

int hang = 0,j = 0,line = 0,lie = 0;

记不清了，去看看program windows 一书。
