Windows 消息发送顺序

代码如下：

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow)
{
   HWND hWnd;

   hInst = hInstance; // Store instance handle in our global variable

   _RPT0(_CRT_WARN, "PreCreateWindow!\n");
   hWnd = CreateWindow(szWindowClass, szTitle, WS_OVERLAPPEDWINDOW,
      CW_USEDEFAULT, 0, CW_USEDEFAULT, 0, NULL, NULL, hInstance, NULL);

   _RPT0(_CRT_WARN, "AfterCreateWindow!\n");
   if (!hWnd)
   {
      return FALSE;
   }

   ShowWindow(hWnd, nCmdShow);
   _RPT0(_CRT_WARN, "AfterShowWindow!\n");
   UpdateWindow(hWnd);
   _RPT0(_CRT_WARN, "AfterUpdateWindow!\n");

   return TRUE;
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    int wmId, wmEvent;
    PAINTSTRUCT ps;
    HDC hdc;

    _RPT2(_CRT_WARN, "%s->%d\n", GetMsgName(message), message);

    switch (message)
    {
    case WM_COMMAND:
        wmId    = LOWORD(wParam);
        wmEvent = HIWORD(wParam);
        // Parse the menu selections:
        switch (wmId)
        {
        case IDM_ABOUT:
            DialogBox(hInst, MAKEINTRESOURCE(IDD_ABOUTBOX), hWnd, About);
            break;
        case IDM_EXIT:
            DestroyWindow(hWnd);
            break;
        default:
            return DefWindowProc(hWnd, message, wParam, lParam);
        }
        break;
    case WM_PAINT:
        hdc = BeginPaint(hWnd, &ps);
        // TODO: Add any drawing code here...
        EndPaint(hWnd, &ps);
        break;
    case WM_DESTROY:
        PostQuitMessage(0);
        break;
    // add by zhangqun;
    case WM_GETMINMAXINFO:
        {
            PMINMAXINFO pMinMaxInfo = (PMINMAXINFO)lParam;
            int a = 10;
        }
        break;
    //case WM_NCLBUTTONDOWN:
    //    _RPT0(_CRT_WARN, "WM_NCLBUTTONDOWN!==============================\n");
    //    break;
    default:
        return DefWindowProc(hWnd, message, wParam, lParam);
    }
    return 0;
}

输出如下：
