实现文件内容

m_RichEdit_ctlContent.SetWindowText(L"富文本测试1234567");
cf.cbSize = sizeof(CHARFORMAT2);
cf.dwMask = CFM_BACKCOLOR | CFM_COLOR | CFM_FACE | CFM_SIZE;      //
cf.crBackColor = RGB(0, 255, 0);       // 背景色
cf.crTextColor = RGB(255, 0, 0); //文字颜色
cf.yHeight = 440;
lstrcpynW(cf.szFaceName, _T("微软雅黑"),32);
m_RichEdit_ctlContent.SetSel(1, 5); // 选中区域文字

m_RichEdit_ctlContent.SetSelectionCharFormat(cf);

指定的字符高度，单位为缇（1 / 1440英寸，或1 / 20的打印机的点）。使用此成员，在dwmask成员中设置cfm_size标志

1 twip=1/1440 inch

1 twip=1/20 point

pint与word字体号的对照

96 px/in screens

以二号字体为例 查表是22Point = 二号

设置数值是22*20=440
