关于Rich Edit Control 字体颜色问题？高分！送！

[Viali]

我在程序里头，Rich Edit contrl的作用是根据要求显示我要显示的字符，而且字符格式不一样的，比如说，如何实现以下功能？
按一下button，就显示“这是第一次”，其中字体为 五号，颜色 红色；
再按一下button，就显示“这是第二次”，字体为 六号，颜色为 绿色。
类似的功能，该怎么实现？？？

CHARFORMAT
The CHARFORMAT structure contains information about character formatting in a rich edit control.

能否提供一个例子？代码？ 求救求救！

我想达到的效果是，一行显示出来后，接着显示下一行，但两行的颜色是不一样的哦，按照你的方法，我写出来后，颜色都变成一样了哦

int flag =0;
void CMy111Dlg::OnButton1()
{
// TODO: Add your control notification handler code here
CHARFORMAT cf;
CString str=_T("这是第一次!\xd\xa");
CRichEditCtrl *MyRich=(CRichEditCtrl*)GetDlgItem(IDC_RICHEDIT1);
cf.dwEffects=CFM_BOLD;
if(flag == 0)
{
cf.crTextColor=RGB(255,0,0);
cf.yHeight = 200;
}
else
{
cf.crTextColor=RGB(0,0,255);
cf.yHeight = 300;
}
MyRich->SetSelectionCharFormat(cf);//应该这样，不好意思
MyRich->ReplaceSel(str);
flag = 1;
}

别忘了IDC_RICHEDIT1．

怪事，我的vc里，加了个RichEdit对话框就显示不出来．
我加了AfxInitRichEdit();就可以显示了，真郁闷！
快考试了，我只能这样简单地写一下，希望你能满意！
