请问如何让rich edit的OnChange函数生效？

[zjcop]

程序中有以下提示，但是我不知道具体操作该怎么做！
If this is a RICHEDIT control, the control will not
send this notification unless you override the CDialog::OnInitDialog()
function and call CRichEditCtrl().SetEventMask()
with the ENM_CHANGE flag ORed into the mask.
按照上面的提示，初始化函数该加些什么代码，CRichEditCtrl().SetEventMask()函数又该在哪里加呢？谢谢！

OnInitDialog()函数中：

CRichEditCtrl().SetEventMask(CRichEditCtrl().GetEventMask()|ENM_CHANGE )；

[老夏Max]

CRichEditCtrl()就是RichEdit控件对应的变量！！

[goodboyws]

BOOL CXXXDialog::OnInitDialog()
{
......

m_cRichEdit.SetEventMask(ENM_CHANGE);
}
