MICROSOFT WINDOWS 8 BUILD STUDY NOTE (4)

HW-59T - Improving performance with the Windows Performance Toolkit

refer: http://channel9.msdn.com/Events/BUILD/BUILD2011/HW-59T

Note:

  • Motivation for performance analysis:
    • Performance related to multiple layered impact such as : hardware, OS, other application and process impact.
  • Stage of performance improvement:
    • Preception –> Measurement –> Analysis.
    • It will be back and forth after analysis and re-preception.
  • Tool list:
    • Trace Capture: Windows Performance Recorder
    • Tacce Analysis: Windows Performance Analizer
  • Things to look out:
    • Don’t assume you know what’s wrong.
    • Don’t enable too much instrumentation
    • Don’t trace longer than you need.

 

PLAT-203T Async everywhere: creating responsive APIs & apps

refer: http://channel9.msdn.com/Events/BUILD/BUILD2011/PLAT-203T

Note:

  • Async only support on some API:
    • XAML, Tile on UI
    • GPS and portable debice on Device
    • All network and communicate
    • Applifetime, Authentication, Crytography on Fundamental
  • Await
    • Await is a simple way to against async API.
    • Await will make the async highest priority and let the compiler know here need to wait the result come back. Code will run as sequencial.
  • Error handling

    • try {

    FileOpenPicker p = new FileOpenPicker();

    p.FileTypeFilter.Add(".jpg");ry

    var operation = p.PickSingleFileAsync();

    operation.Completed = (IAsyncOperation<StorageFile> f) =>

    {

    MyButton.Content = f.GetResults().FileName;

    };

    operation.Start();

    catch(...) {}

    • try catch will only cover RED one, it need refine code to cover whole scope

    try {

    FileOpenPicker p = new FileOpenPicker();

    p.FileTypeFilter.Add(".jpg");

    MyButton.Content =

    (await p.PickSingleFileAsync()).FileName;

    } catch(Exception e) {}

    • It will separate into “RED” and “Green” one but still cover on try catch.
  • 5 top tips from presenter.
    • Don’t worry about the COM apartment.
    • Remember to start your operation.
    • File picker cancel != Async Cancel
      • It will complete but return NULL.
      • “use exception for exceptional things”
    • Don’t worry about Dispatcher.Invoke…
    • Don’t worry about the concurrency

MICROSOFT WINDOWS 8 BUILD STUDY NOTE (3) ABOUT touch

APP-186T - Build advanced touch apps in Windows 8

refer: http://channel9.msdn.com/Events/BUILD/BUILD2011/APP-186T

  • Major point of touch app design:
    • Unify pen and touch into PointerPoint
    • Get mouse and pen for free
    • performance performance and performance
  • Touch and Gesture support in framework
    • Metro app with HTML or XAML—> Gesture event
    • ICoreWindow –> Using point (touch simulate mouse click)
    • Windows Runtime –> PointerPoint with GestureRecognizer
  • PointerPoint:
    • Whole related point implement is here, HID data also can get using PointerPoint.
  • GestureRecognizer:
    • It just like the Win7 multiple touch support on MSFT, it support kind of gesture such as:
      • Tap, Hold, rotate and Scale
    • But more support on Win8 such as:
      • HoldWithMouse?
      • RightTap
        • To simulate with right click on mouse, such your finger about right click here.
        • mmmm….. it should be MSFT patent here for right click.
  • For desktop developer, MSFT also support full Windows Runtime about Gesture support –> Great!
    • WM_Point –> the same as usual
    • InteractionContexts –> mirror GestureRecognizer. Don’t forget WM_TOUCH and WM_GESTURE still support here.
    • Pointer device –> identify source device (touch panel, mouse or other.)

Web browser for Windows 8

It need note that Windows 8 has two version of IE (it should say, one application but two entry for different mode)

  • Desktop IE
  • Metro IE

But it is very tricky, if you type “open http://Web” on desktop explorer will open “Metro IE”

When you try to use this command to open web side, please note metro browser will be default option, not desktop browser.

ShellExecute(NULL,TEXT("open"), TEXT("http://msdn.microsoft.com"), TEXT(""),NULL,SW_SHOWNORMAL);

To specific using desktop browser, it should specific command on [HKEY_CLASSES_ROOT\http\shell\open\command]

  • Multi-select already support just add one propoties on it. (selectionMode = 'multi’)
  • ListView is easy to grouping if you could provide detail data of each item, group rule and group render (to descript how to group).
  • Symantic Zoom:
    • It is a way to zoom out/zoom in by semantic  (such of “category”, “date”). It look like “Group By”.
    • ListView also provide semantic zoom.
    • Easy to implement to change <div id> to “zoomOutView” and related data control.
  • If app is snapped (snapped on side).

iOS5更新心得

iOS5 upgraded, 幾個重點記錄一下:
1. C槽請有夠大空間~ 避免更新時候的備份掛點~
2. 請記得先把購買的部分全部傳到iTune
3. 要事前備份避免任何意外(連你下載檔案都先備份)
4. App 要sync 到iTune 不然就得重新下載然後自己排位置
5. iCloud 設定要設好~  app 裡面東西先不用上雲端~ 避免爆掉(每人免費5G)
6. 更新中網路不要斷(可以先下載避免意外)
兩篇文章可參考

Microsoft Windows 8 build study NOTE (1)

 

BPS-1006 Tools for building Metro style apps

Refer video: http://channel9.msdn.com/Events/BUILD/BUILD2011/BPS-1006

Note:

It is introduction of VC2011, here is some major demo topic as follows:

  • Auto spell which is powerful with Visual Assist
    • Auto spell, finding related function and method. It is easy to go.
  • JS debugging:
    • It is cool to have debugger for JS which also support all debugging window (variable, watch…)
  • Parallel stack debugging windows:
    • It has visualization debugging tab for parallel which could show currently threading and each thread dependency.
  • RT XAML editor:
    • During debugging you also could editing XMAL code by select on UI or select on code segment to show UI change on fly.
  • Simulator debugger:
    • I think it is very cool stuff for me such we don’t have multiple touch panel on hand but we need implement some related to “Share”, “Search” which need finger slip.
    • It also provide “finger”, “rotate”, “zoom” and it could simulate to different resolution for Metro UI debugging.
  • Asynchronous programming (await, async)
    • Refer here for more detail:
    • Concept:
      • Will folk another thread after “await” and response on original message loop to ensure response quickly.
      • It look like to cut original message thread,one back to main and another keep doing async task.
      • It help us to using linear thinking to do asynchronous programming
    • Sample: (from here)

        async void ArchiveDocuments(List<Url> urls)
        {
          Task archive = null;
          for(int i = 0; i < urls.Count; ++i)
          {
            var document = await FetchAsync(urls[i]);
           if (archive != null)
               await archive;
            archive = ArchiveAsync(document);
           }
        }

    BPS-1005 Platform for Metro style apps

    Refer video: http://channel9.msdn.com/Events/BUILD/BUILD2011/BPS-1005

    Note:

    • What is major different between Metro UI application with desktop application?
      • No overlay window architect (all full screen)
      • No message box related API.
    • Device access all using asynchronous to ensure all application could response on time.
    • About “Broker” in WinRT concern as follows:
      • Impact system integrity.
      • Impact user data
      • Impact User private
    • HTML5/CSS/JS great for Metro Apps
      • MSFT try to enlarge their engineer base and try to draw Web engineer’s attention to join Metro Apps development.
    • Package your application:
      • Application could be easily to pack and upload to MSFT with one click on VS11.
      • All package need digital signature before upload to App Store

      TOOL-789C Bringing existing C++ code into Metro style apps

      Refer video: http://channel9.msdn.com/Events/BUILD/BUILD2011/TOOL-789C

      Note:

      • About Metro UI app:
        • No registry, GDI, MessageBox coding.
      • Here is work/not work desktop app
        • Work:
          • Standard C++
          • Parallel pattern
          • Win32 (WinRT and Win32 subset)
          • ATL (ATL subset)
        • Not work:
          • MFC
      • About WinRT
      • Q&A
        • Two Metro UI don’t have any way to communicate for now, currently it still isolate.
        • For disable API, it might change depends engineer feedback to MSFT.
        • All Metro UI need component could be pack to WinRT component and package today to delivery to end-user via store.
        • Shared component is not work on Metro UI, all component must be side-by-side. Because you could not use CoCreateInstance by CLSID, so there is unique CLSID on Metro world.
        • Whole app on Metro UI are isolate due to security and system integrity.

      讀書心得-天哪！我居然CC給他

      • 作者：雪麗．泰勒
      • 原文作者：Shirley Taylor
      • 譯者：晴天
      • 出版社：大是文化
      • 出版日期：2009年12月28日
      • 大綱:

        你有看過這種電子郵件嗎？還是你一直都這麼做，卻不以為意？
        ．郵件隨意CC，越級報告或洩漏公事了還不知道。
        ．同一件事來回「Re:」寫好幾封信，到底要我看哪封？
        ．郵件寫了五、六百字，看到昏頭卻沒寫清楚要我幹嘛？
        ．又忘記加附件了，讓客戶覺得這傢伙（跟這間公司）真是不可靠！
        ．按下「回覆全部」，才發現有人不該是收件人。
        ．打電話三分鐘就能完整說明的事，偏偏要用電子郵件慢慢來。

        E-mail誰不會寫？而且不用一秒就能按下「傳送」鍵，但如果闖出大禍，你得花幾萬倍的時間滅火，這不但會拖累你的工作效率，更有可能毀了你的專業形象和前途。

      心得:

      其實有點忘記~ 為什麼當初會買這本書。不過看了這本書之後~ 到是真的學了不少了。而且有趣的是~ 工作的越久~ 越覺得這本書裡面所要闡述的概念就越來越重要~ 不過在大綱裡面所提到的幾個錯誤到是真的太誇張了。反倒是書裡面其他提到的失誤到是真的很常見而且又很重要…
