Richedit::CHARFORMAT2   cf2;   
  cf2.cbSize   =   sizeof(cf2);   
  cf2.crTextColor   =   clRed;   //   红色前景   
  cf2.dwMask   =   CFM_BACKCOLOR   |   CFM_COLOR;   //   多加一个CFM_COLOR   
  cf2.crBackColor   =   clYellow;   //   黄色背景   
  RichEdit1->Perform(EM_SETCHARFORMAT,   SCF_SELECTION,   (LPARAM)&cf2);

Answer 1

while (m_strContent.Find(m_strFind, nStartPos)!=-1)
{
nStartPos = m_strContent.Find(m_strFind, nStartPos);
nStopPos = nStartPos + m_strFind.GetLength();
m_edit.SetSel(nStartPos, nStopPos); CHARFORMAT cf;
cf.cbSize = sizeof(CHARFORMAT);
m_edit.GetSelectionCharFormat(cf); cf.crTextColor = 255;
cf.dwMask = CFM_COLOR;
if (cf.dwEffects & CFE_AUTOCOLOR)
cf.dwEffects -= CFE_AUTOCOLOR; m_edit.SetSelectionCharFormat(cf);
nStartPos = nStopPos;
iFind++;
}

Answer 2

The following code is set text to bold:m_ctrlRichEdit.GetSel(nStartChar, nEndChar); 
 CHARFORMAT cf; 
 cf.dwMask = CFM_STRIKEOUT|CFM_BOLD; 
 cf.dwEffects = CFE_BOLD; 
 m_ctrlRichEdit.SetSelectionCharFormat(cf); First of all, you'll have to set the size field of the CHARFORMAT struct. 
Second, you'll want to check the dwMask field, you don't have to set the 
strikeout-flag in your case. Check the rest of the possible values for this 
struct, and you'll be able to change the color. 
For the background, you'll need CHARFORMAT2 and SendMessage to the control to set instead of SetSelectionCharFormat.

Answer 3

Perform?CRichEditCtrl::SetSelectionCharFormat 
自己填正确CHARFORMAT就可以了。
