multiline editbox

Hi
How would I go about adding more than 1 line of text to the edit box? I've looked at WM_SETTEXT but that will only add text to the first line, the EM_LINESCROLL won't scroll to a new line and the other EM scroll messages dont want to work either. Its probably a message ive overlooked but when you've been staring at the same code for hours...well you know how it is :)

void PostText(HWND hedit, string message)
{
message+="\r\n";
int ndx = GetWindowTextLength (hedit);
SendMessage (hedit, EM_SETSEL, (WPARAM)ndx, (LPARAM)ndx);
SendMessage (hedit, EM_REPLACESEL, 0, (LPARAM) ((LPSTR) message.c_str()));
}
