I am doing socket program and not able to receive msg from client side

//Server side
void CMFCExampleDlg::OnReceive(int nErrorCode)
{   
  recv(clientsocket,"200" , 1024, 0);
  m_name.SetVariable("gear","1");
}


//client side
BOOL CMFCClientDlg::PreTranslateMessage(MSG* pMsg)
{
  if(pMsg->lParam==VK_NUMLOCK)
    send(s,"200",1024,0);

  return 0;
}
