最近再研究如何寫出一個aggregator, 首先把LINQ跟JSON都看了一下。試著想找出一可以方便在各大相片網站找資料的共通語言，由於codeplex上面有Linq.Flickr這個open source 的library，也開始試著研究。

參考: 使用linq.flickr搜尋相片

Note:

1. 由於改WLWPlurk，稱這次機會把手邊平台由VS2008改成VS2010。也裝了Visual Studio Achievements。

2. 為了開發快一點也把順手語言改成C#，不過後來發現Linq.Flickr是.Net3.5的~ 竟然也踩到了3.5 與 4.0 不共通的弊病。 所以也在Add reference 卡了一下。

3. Flickr user name 不是URL上面的userID 而是user definded 的名字，為了這個我還以為是我安裝有問題~ 認真的trace 下Linq.Flickr去。

由於要修改去年寫給自己用的小工具 (WLWPlurk)，看到其他在Codeplex上面的人都是用WIX(Windows Installer XML)來做包裝plugin的動作。

所以也去好好的搜尋一下有沒有相關可以用的東西。 由於我自己也不是專業在做Installer的人~ 裡面的一些設定也真的把我搞糊塗，才了解前因後果。還好找到了相關的文件WiX Script for installing Live Writer Plugins，雖然他上面的sample是針對 WIX 2.0，不過我也把它修改過後分享給大家。

希望有需要的人就拿去用吧。

1. Install WIX 3.6 from http://wix.sourceforge.net/downloadv3.html

2. Setup your path setting to your install path.

3. Inser follow code (it should be XXX.WXS)
   (refer from http://wlwextensionlearning.blogspot.com/2012/02/windows-live-writer-plugin-how-to.html)

4. You might need repace follow string as follows:
   1. {$Plugin Name$} : your plugin name

2. {$InstallGUID$}: A GUID for your installation program 
   
3. {$Manufacturer$}: Manufacturer name 
   
4. {$PluginGUID$}: A GUID for your plugin 
   
5. {$Description$}: A description for your plugin 
   
6. {$FILE_ID$}: ID for your binary which need install. (could be multiple file) 
   
7. {$FILE_NAME$}: Name for your binary which need install. (could be multiple file) 
   
8. {$FILE_Address$}: File address for your binary which need install. (could be multiple file) 

1. Compiler your WIX source code
   1. candle XXX.wxs

2. light -ext WixUIExtension XXX.wixobj 

這幾天弄了好久~ 好不容易把Windows Installer XML (WIX) 3.6給搞懂。
等等寫另外一篇來記錄詳細資料，在這裡先請有需要安裝檔的去下載吧。

http://wlwplurk.codeplex.com/releases/52834/download/342411

有任何需要改進的麻煩留言告訴我!!

欠了好久~ 總算一口氣把它寫完:
請到這裡下載: http://wlwplurk.codeplex.com/

1. Upgrade code with VS2010.
2. Add login page for change account. Using registry to save your login information.
   
3. Add post content page to let you modify your plurk before post it.
   

How to use it:
Just download this binary, extract it and put on your Windows Live Writer plugin folder such as C:Program FilesWindows LiveWriterPlugins

This project implement base on two major component:

1. Json.net (http://json.codeplex.com/)
2. NPlurk (http://nplurk.codeplex.com/)
   You need plurk API key from http://www.plurk.com/API/ to use this source code.

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 f) => { MyButton.Content = f.GetResults().FileName; }; operation.Start(); catch(...) {}</blockquote> * 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 Refer: [http://blogs.msdn.com/b/ericlippert/archive/2010/10/29/asynchronous-programming-in-c-5-0-part-two-whence-await.aspx](http://blogs.msdn.com/b/ericlippert/archive/2010/10/29/asynchronous-programming-in-c-5-0-part-two-whence-await.aspx)

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.)
