在IE的连接对话框中，点击连接后，最下面的edit框中出来的信息可以一行一行的显示，请问这是怎么实现的，最好举个例子，马上给分！

CComboBoxEx m_wndAddress;
if (!m_wndAddress.Create(CBS_DROPDOWN | WS_CHILD, CRect(0, 0, 200, 120), this, AFX_IDW_TOOLBAR + 1))
{
TRACE0("Failed to create combobox\n");
return -1; // fail to create
}
CString str;
m_wndAddress.GetEditCtrl()->GetWindowText(str);
COMBOBOXEXITEM item;
item.mask = CBEIF_TEXT;
item.iItem = -1;
item.pszText = (LPTSTR)(LPCTSTR)str;
m_wndAddress.InsertItem(&item);

void AddLine(HWND hwndEdit, char * lpszString)
{
char szCRandLF[3] = "\r\n";
::SendMessage(hwndEdit, EM_SETSEL, -2, -1); //将当前位置设在Edit控件的最后并清除当前选择
::SendMessage(hwndEdit, EM_REPLACESEL, 0, lpszString); //添加一行字符
::SendMessage(hwndEdit, EM_REPLACESEL, 0, szCRandLF); //添加换行
}
