CEdit   edit   =   GetDlgItem(   IDC_EDIT1   );  
  int   len   =   GetWindowTextLength(   edit.m_hWnd   );  
  edit.SetSel(   len,   len   );  
  edit.ReplaceSel(   "要添加的文字"   );

 

 

//buffer内容是串，IDC_MSG是edit的id，hwnd是窗口的句柄  
  ::SendMessage(GetDlgItem(hwnd,IDC_MSG),EM_SETSEL,-1,0);  
  ::SendMessage(GetDlgItem(hwnd,IDC_MSG),EM_REPLACESEL,false,(long)buffer); 

 

 

 CString str="lfdkjsf/r/n";
  int  nLength=m_edit.SendMessage(WM_GETTEXTLENGTH);      
  m_edit.SetSel(nLength,nLength);      
  m_edit.ReplaceSel(str);
