Here's what I use; placed in the main application module (InitInstance):
 CWnd* pPrevApp = CWnd::FindWindow(NULL, "MyApp");
 if(NULL != pPrevApp)
 {
  pPrevApp->PostMessage(WM_QUIT); // or WM_CLOSE
  do
  { Sleep(250); }
  while(pPrevApp = CWnd::FindWindow(NULL, "MyApp"));
 }

There are issues with orderly shutdown however; especially when running
threads are present. For this purpose you'll have to cover both the
ExitInstance() and the OnQueryEndSession() message handlers to effect an
orderly shutdown.

An alternative method would be to create a globally named event and signal
it to shut down the previous instance...
