Re: My app's window class

I'm fishing around for examples for how to register my CMainFrame class.
I'm looking at this right now:

BOOL CSampleApp::InitInstance()
  {
  /********************************************************************/
   // If a previous instance of the application is already running,
   // then activate it and return FALSE from InitInstance to
   // end the execution of this instance.

   CWnd *pWndPrev;

   // Determine if another window with your class name exists...
   if (pWndPrev = CWnd::FindWindow(_T("WCE_MyNewClass"),NULL))
   {
       // Bring previous instance to the foreground
pWndPrev->SetForegroundWindow();
return FALSE;
   }
   WNDCLASS wndcls;

   memset(&wndcls, 0, sizeof(WNDCLASS)); // start with NULL defaults

   wndcls.style = CS_DBLCLKS | CS_HREDRAW | CS_VREDRAW;
   wndcls.lpfnWndProc = ::DefWindowProc;
   wndcls.hInstance = AfxGetInstanceHandle();
   wndcls.hIcon = LoadIcon(IDR_MAINFRAME); // or load a different icon
   wndcls.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1);
   wndcls.lpszMenuName = NULL;
   // Specify your own class name for using FindWindow later
   wndcls.lpszClassName = _T("MyNewClass");

   // Register the new class and exit if it fails
   if(!AfxRegisterClass(&wndcls))
   {
      AfxMessageBox(_T("Class Registration Failed\n"));
      return FALSE;
   }
  /********************************************************************/
  // Other code here...
  }

How much of that applies to what I need to do?
