CEdit *pEt = (CEdit *)GetDlgItem(IDC_EDIT_RECV);  
//方式1
int nLen = GetWindowTextLength(pEt->m_hWnd); 
pEt->SetSel(nLen, nLen); 
pEt->ReplaceSel("要添加的文字");

//方式2
::SendMessage(GetDlgItem(hwnd,IDC_EDIT_RECV),EM_SETSEL,-1,0); 
::SendMessage(GetDlgItem(hwnd,IDC_EDIT_RECV),EM_REPLACESEL,false,(long)buffer);

//方式3
CString str="append/r/n";
int  nLength=pEt->SendMessage(WM_GETTEXTLENGTH);   
pEt->SetSel(nLength,nLength);   
pEt->ReplaceSel(str); 

//自动滚屏
pEt->LineScroll(pEt->GetLineCount());
