如果要继续查找，修改cpMin,如
int nCount = 0;
do
{
long lPos = GetRichEditCtrl().FindText(0, &ft);
if( -1 == lPos) break;
ft.chrg.cpMin = lPos + strlen(ft.lpstrText);
++nCount;
}while(TRUE);
g.以Html格式保存
目前做法可先转为RTF格式，再通过RTF-to-HTML Converter
http://www.codeguru.com/Cpp/controls/richedit/conversions/article.php/c5377/
h.重载OnProtected函数得到对应的消息，如粘贴等
void CMYichEditorView::OnProtected(NMHDR* pNMHDR, LRESULT* pResult)
{
ENPROTECTED* pEP = (ENPROTECTED*)pNMHDR;
switch (pEP->msg) {
case WM_KEYDOWN://按键，判断pEP->wParam
case WM_PASTE://粘贴
case WM_CUT://剪切
case EM_SETCHARFORMAT:
default:
break;
};
*pResult = FALSE;
}
三.聊天常用
a.LINK 链接功能
1. LoadLibrary(_T("Riched20.dll"));
2. 创建RichEdit2.0控件
CreateEx(0, _T("RichEdit20A"), NULL, WS_CHILD|WS_VISIBLE|WS_VSCROLL|WS_TABSTOP
|ES_READONLY|ES_WANTRETURN|ES_MULTILINE,
rect.left, rect.top, cx, cy,
pParentWnd->m_hWnd, (HMENU)nID, NULL);
3. 设定选中的文字为链接显示
CHARFORMAT2 cf2;
ZeroMemory(&cf2, sizeof(CHARFORMAT2));//
cf2.cbSize = sizeof(CHARFORMAT2);
cf2.dwMask = CFM_LINK;
cf2.dwEffects |= CFE_LINK;
m_cRichEdit.SendMessage(EM_SETCHARFORMAT, SCF_SELECTION, (LPARAM)&cf2);
4.支持链接的点击响应
m_cRichEdit.SetEventMask(ENM_LINK);
5.响应链接的点击EN_LINK
BEGIN_MESSAGE_MAP(CMyRichEdit, CRichEditCtrl)
ON_NOTIFY_REFLECT(EN_LINK,OnURL)
END_MESSAGE_MAP()
......
void CMyRichEdit::OnURLClick(NMHDR *pNmhdr, LRESULT *pResult)
{
TCHAR LinkChar[512];
ENLINK *pLink = (ENLINK *)pNmhdr;
if (pLink->msg == WM_LBUTTONUP)
{
SetSel(penLink->chrg);//这是链接的文字范围
long Res = GetSelText((char *)LinkChar);//这是链接文字
//后面是你的处理过程
......
}
}
b.插入位图

自定义在RichEdit中插入对象的图标
http://www.blogcn.com/user3/jiangsheng/blog/1319738.html
方法基本同Knowledge Base文章Q220844 HOWTO: Insert a Bitmap Into an RTF Document Using the RichEdit Control
只是在最后插入之前调用一下IOleCache::SetData,用一个HGLOBAL作为参数，HGLOBAL里面的数据是一个METAFILEPICT结构，包含自己提供的图片
使用CRichEditView::InsertFileAsObject就可以插入图像。VC++带有一个例子WordPad。
另外可以参考“Insert any HBITMAP (Bitmap) in your RichEdit Control”(http://www.codeguru.com/richedit/richeditrc.html)。
c.显示GIF动画
常用的是通过qq的imageole.dll(也有用Gif89.dll的)
