m_RichEdit.SetWindowText("The text for test!"); 
m_RichEdit.LockWindowUpdate();
m_RichEdit.HideSelection(TRUE, FALSE);
CHARRANGE crOldSel;
m_RichEdit.GetSel(crOldSel);
m_RichEdit.SetSel(0,-1); //trying to make "The" red
CHARFORMAT cf;
cf.cbSize = sizeof(cf);
m_RichEdit.GetSelectionCharFormat(cf);
//****
cf.dwMask=CFM_COLOR;
//****
cf.crTextColor = RGB(255,255,0);
m_RichEdit.SetSelectionCharFormat(cf);
m_RichEdit.SetSel(crOldSel);

m_RichEdit.UnlockWindowUpdate();

解决方案1:

CHARFORMAT CH2;
         CH2.dwMask=CFM_SIZE|CFM_COLOR;
         CH2.dwEffects=CFE_BOLD;
         CH2.yHeight=300;
     CH2.crTextColor=RGB(255,0,0);
         m_cPin.SetWordCharFormat(CH2);
