Here's a slight modification, making some obvious assumptions

function x
  m_socket->Send("some text");
  CString cs;//(Or whatever your return type is)
     cs = m_socket->Reply();
  }while(cs.IsEmpty());//or equiv...
  return cs;

What about doing something like this
//Global flag
BOOL m_bReplyCame = FALSE;

function x
m_socket->Send("some text");

//Usually there will be a thread to read the socket. In that thread
//if u got the reply then set that flag value to TRUE, so the while loop ends.
//and function returns. Take care to write that in a separate thread as u can notice, if socket is not read in separate thread, ur program is having a infinite loop!!!.

Try it out.
