  public class private gallery activity {Private int count; Private bitmap [] thumbnail; Private Boolean [] Thumbnail selection; Private string [] arrPath; Private Image Adapter Image Adapter; ArrayList & LT; String & gt; F = new ArrayList & lt; String & gt; (); // file path list file [] listFile; Private reference mcontext; /** Called when the activity is first created. * / @ Override Crate on Public Zero (Bundle Saved Instantstate) {Super. Contents (Saved Instantstate); SetContentView (R.layout.gallery); GetFromSdcard (); GridView imagegrid = (GridView) findViewById (R.id.PhoneImageGrid); ImageAdapter = New ImageAdapter (); Imagegrid.setAdapter (imageAdapter); Imagegrid.setOnItemLongClickListener (New OnItemLongClickListener) {@Override Public Boolean onItemLongClick (see AdapterView & LT;?> Parents, View, Integer Status, Long ID) {// TODO Automatic Created Method Stub file afile = New File (f.get (status); if (afile.delete ()) {toast.makeText (getApplicationContext), "file delete", toast.LENGTH_LONG) .show ();} else {toast.makeText (getApplicationContext ( ), "File not deleted", Toast.LnnHH_LOG) Show ();} Return false;}}); ; Imagegrid.setOnItemClickListener (New OnItemClickListener) {Public Zero onItemClick (AdapterView & LT;?> Parents, View V, Integer Position, Long ID) {file afile = new file (f.get (position)); Toast MakeText (getApplicationContext (), F.Jet (status), Toast.LnnHH_LOG) Show ();}}); } Public Zero getFromSdcard () {file file = new file ("/data/data/com.mati.testprivatefolder/cache/MyPrivateFolder2//"); If (file.isDirectory ()) {listFile = file.listFiles (); For (int i = 0; iFile.length; i ++) {if (listFile [i] .isDirectory ()) {} else {f.add (listFile [i] .getAbsolutePath ()); }}}} Public Class ImageAmidator Base Expands Expand {Public LayoutsInfLaterM Inflator; Public image adapter () {mInflater = (layoutInflator) getSystemService (reference.

In flat (R.layout gallery item, empty); Holder .imageview = (ImageView) Convertview. FundaubiIID (RID Thumb Image); ConvertView.setTag (holder); } And {holder = (seeholder) ConvertView.gettag (); } Bitmap myBitmap = BitmapFactory.decodeFile (f.get (status)); Holder.imageview.setImageBitmap (myBitmap); Return Convertview; }} Class Vendor {ImageView imageview; }}

I am trying to use the ASP.NET signal for the first time - here's what I did: created a new web Has been added to the project and the following signal R packages: I have created the following category: [Hub-name ("chat")] Public class ChatHub: Hub {Public Zero Halo () {Clients.All.hello ( ); }} and the following startup configuration: public partial class startup {public zero configuration (IAppBuilder app) {configure (app); App.MapSignalR (); }} However, whenever I navigate localhost: (port) / api / signalr / chat I get the following error: Protocol error: Unknown transport.

Registering an Interceptor For All Interface Implementaions in Castle Windsor -

-
I'm quite new to the castle and especially to the Windsor using Interceptors and if it's all across a It is possible to register the interceptor, in return, instead of specifying each implementation, implementing a particular interface. For example, I have an interface called IComponent , which will be implemented by multiple classes. I have a ComponentInterceptor class written to work on these classes when they have performed a particular method, I want to do something like this: _container Register (Component.For & LT; IComponent & gt; () .Interceptors ("ComponentInterceptor") .LifestyleSingleton ()) Rather than what to do: _container.register (Component.For & lt; IComponent & gt; (). ImplementedBy & lt; Componenta & gt; () .Interceptors ("ComponentInterceptor") .LifestyleSingleton ()), _container.Register (Component . & Lt; IComponent & gt; (.) ImplementedBy & LT; ComponentB & gt; () .Interceptors (...
