RichEdit默认情况下并不响应这个消息，如果想要用这个消息，就要在OnInitDialog中设置RichEdit的属性。
m_RichEdit.SetEventMask( m_RichEdit.GetEventMask() | ENM_CHANGE );
m_RichEdit.SetEventMask( m_RichEdit.GetEventMask() | ENM_CHANGE );

m_RichEdit.SetEventMask(EN_CHANGE)

更正一下，是在对话框初始化函数OnInitDialog()或是视图的初始化函数OnInitialUpdate()，不是在应用程序初始化函数中加代码！不好意思了！一时笔误！

在程序初始化函数OnInitInstance()函数中加上下面的代码就可以了！
m_ctlRichEdit.SetEventMask(m_ctlRichEdit.GetEventMask() | ENM_CHANGE);
其中参数的各种含义楼上的已经给列出来了，参考一下！
祝你成功！
m_ctlRichEdit.SetEventMask(m_ctlRichEdit.GetEventMask() | ENM_CHANGE);

// Set the event mask so that the parent gets notified when the text
// of the rich edit control changes.
pmyRichEditCtrl->SetEventMask(pmyRichEditCtrl->GetEventMask() |
ENM_CHANGE);
