编辑框为CRichEditCtrl,在CWinApp中的InitInstance中添加AfxInitRichEdit2方法，然后使用CHARFORMAT这个结构设置字体风格与颜色，在对话框上放置CRichEditCtrl,然后为对话框类关联变量m_RichEditCtrl
int i=1; //第二行行号
int start=m_RichEditCtrl.LineIndex(i); //第二行开始的索引号
int end=m_RichEditCtrl.LineIndex(i+1); //第三行开始的索引号

m_RichEditCtrl.SetSel(start,end);//全选第二行文本
CHARFORMAT cf;

m_RichEditCtrl.GetSelectionCharFormat(cf);

cf.dwMask|=CFM_BOLD;

cf.dwEffects|=CFE_BOLD;//设置粗体，取消用cf.dwEffects&=~CFE_BOLD;

cf.dwMask|=CFM_ITALIC;

cf.dwEffects|=CFE_ITALIC;//设置斜体，取消用cf.dwEffects&=~CFE_ITALIC;

cf.dwMask|=CFM_UNDERLINE;

cf.dwEffects|=CFE_UNDERLINE;//设置斜体，取消用cf.dwEffects&=~CFE_UNDERLINE;

cf.dwMask|=CFM_COLOR;

cf.crTextColor = RGB(255,0,0);//设置颜色

cf.dwMask|=CFM_SIZE;

cf.yHeight =200;//设置高度

cf.dwMask|=CFM_FACE;

strcpy(cf.szFaceName ,_T("隶书"));//设置字体
m_RichEditCtrl.SetSelectionCharFormat(cf);

可以用这样来设置
CHARFORMAT cf;
ZeroMemory(&cf, sizeof(CHARFORMAT));
cf.cbSize = sizeof(CHARFORMAT);
cf.dwMask = CFM_BOLD | CFM_COLOR | CFM_FACE |
CFM_ITALIC | CFM_SIZE | CFM_UNDERLINE;
cf.dwEffects = 0;
cf.yHeight = 16*16;//文字高度

if(nhight>0)
cf.crTextColor = RGB(255,0,0); //文字颜色
//else
// cf.crBackColor = RGB(0,255,0); //文字颜色
strcpy(cf.szFaceName ,_T("Arial"));//设置字体

//m_richedit1.SetSel(1, 5); //设置处理区域
this->SetSelectionCharFormat(cf);
this->ReplaceSel(strLine);
this->ReplaceSel("\n");
