when use ngCordova socialSharing plugin. there is a method 『canShareVia』 which can share to specific social application by it’s appPackageName.

To Line(http://line.me) the packageName is jp.naver.line.android

var lineAppPackageName = 'jp.naver.line.android';
$cordovaSocialSharing
.shareVia(lineAppPackageName, content, subject, null, '')

Response::Download() in Laravel 4.x needs php_fileinfo extension. Sometimes web hosting server doesn’t have that extension on, althought it’s default for php 5.4.

so the way to work around is make a response, and add header to it. See code below

1

5
$file = File::get($filepath);
$response = Response::make($file, 200);
$response->header('Content-Type', $item->mime);
$response->header('Content-Disposition','attachment;filename="'.$filename.'"');
return $response;

之前有寫過一篇有關[Laravel] Laravel with Angular, 但是這個方法在Laravel 5.0裡面是不合用的

所以laravel 5.0的作法如下 在 app/Exceptions/Handler.php 裡修改render function

1

6
public function render($request, Exception $e)
{
if ($e instanceof \Symfony\Component\HttpKernel\Exception\NotFoundHttpException)
return response()->view('index')->header('Content-Type', 'text/html');
return parent::render($request, $e);
}

這個效果等於laravel 4.x的app::missing

Kinect Data Source

- Color
- Infrared
- Depth
- Body
- BodyIndex    

For Windows 8.1 App

- 開啟microphone, webcam權限
- 加入WindowsPreview.Kinect
- 建置CPU設定為x86

取得kinectSensor的方式

this.sensor = KinectSensor.GetDefault();
this.sensor.Open();
this.sensor.Close();

Readers

InfraredFrameReader reader = this.sensor.InfraredFrameSource.OpenReader();
reader.FrameArrived += InfraredReaderFrameArrvied;

Frame references

- Send in frame event args
- AcquireFrame : access to the actual frame
- RelativeTime : allow to templorally correlate frames

{
using (InfraredFrame frame = args.FrameReference.AcquireFrame())
{
if (frame != null)
{
// Get What you need from the frame

}
}
}

Frame

- Gives access to the frame data
    - Make a local copy of access the underlying buffer directly
- Contains metadata for the frame
    - Color, Format, width, height,etc.
- Important: Not Disposing frames will cause you to not receive more frames

Xbox One 同時推出Kinect v2,提供更強大的硬體功能及軟體功能, 剛好手上的案子也差不多到一個段落了。 所以決定來學習Kinect的開發

前置準備

  1. Kinect for windows
  2. 如果已經有了xbox one, 可以只買kinect adapter轉接器就可以了 巴哈
  3. Kinect sdk 2

硬體需求

  1. CPU: i7(建議)
  2. RAM: 4GB(建議)
  3. GPU: DirectX11 (必須)
  4. USB 3.0(必須)
  5. OS: Windows 8.0/8.1(必須)

詳細細節請參考官方網站

已經買了adapter, 等東西寄到後就可以開始學習了

當laravel想要好好的跟angular在一起時,Route都是他們之間的第三者。 前一陣子有發現一個還不錯的方式可以讓Laravel的Route失效。那就是利用

App::missing(function($exception)
{	
	return View::make('index');
});
```

這樣子的設定,就可以不用讓Laravel一直回傳index頁面. 如果需要其他路由設定時,就直接在上面新增即可.

當這樣子設定時,html頁面就可以放在public folder下面,不用使用blade template. 好處是,不用再多學習blade的語法。angular的操作也比較直覺。

Angular裡面有一個方法可以把# (hash tag) 給拿掉,那就是將html5mode開啟

1
2
3
$locationProvider.html5Mode(true).hashPrefix('!')

// 這應該會要求設定<base href="/">

但是如果angular route是架構在asp.net mvc上面,那就會有route打架的情形發生, 或著reload page會出現頁面錯誤的訊息 網路上面的資訊也有很多種版本,以下我也提供一下我的版本

主要重點, asp.net的routeConfig裡面也要同時間定義angular route的部份,但是controller/action是指到index page

1
2

4
routes.MapRoute("member_edit",
"member/edit/{.Catchall}",
new { controller = "Home", action = "Index" },
namespaces: new[] { "Demo.Areas.member.Controllers" });

.state('main.edit', {
url: 'edit/:id',
views: {
'list@main': {
controller: 'editFavorController',
controllerAs: 'vm',
templateUrl: 'Home/EditFavor'
}
}
})

這樣子的設定, 可以讓其他頁面直接用網址的方式開啟那個頁面(請搜尋 deep link angualr)

當設定完成後,卻又發現另外一個問題,問題是, 我在選單連結的部份,有一些是要跑mvc本身的actionlink的動作, 但是angular會先處理 < a > 的動作,所以要跳過這個動作,可以利用 window.location.replace 來處理
