CFontDialog选择字体
然后CreateFont+SetFont

需要在CEditview的父窗口里重载OnCtrlColor消息.
就好了

能不能给个具体的代码？
比如响应菜单消息：
void CNotepadView::OnEditFont() 
{
// 弹出字体选择对话框：
...
// 应用字体：
...
}

我程序里的一段,用来选择字体, 各种字体以对应的字体显示

字体显示在对话框中的LISTBOX里

谢谢各位!
后来查了MSDN发现:不能直接对CEditView调用SetFont(),
必须创建一个类成员变量CFont font和LOGFONT lf,然后使用
CEditView::SetFont(font)就可以了.
