WPF Custom Behavior

(1) Behavior is a gneric type <>, non-generic one has no public ctor
(2)  Need System.Interactivity.Dll from Blend SDK or MVVM light donwload

<Window x:Class="TestCustomBehavior.MainWindow"

WPF Printing using FixedDcoument

Print Preview Popup as FixedDocument

(1) PageContent will has Compiler Error but can stil render with FixedPage---Known Defect of WPF.
(2) Fixed document will has toolbar shown by WPF, no coded needed. So this is simplest printing

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    <FixedDocument Name="customerReport">

        <PageContent>

            <FixedPage>

Using AppFabric

Client App Config:

<configSections>
    <!-- required to read the <dataCacheClient> element -->
    <section name="dataCacheClient" type="Microsoft.ApplicationServer.Caching.DataCacheClientSection,
            Microsoft.ApplicationServer.Caching.Core, Version=1.0.0.0, 
            Culture=neutral, PublicKeyToken=31bf3856ad364e35" allowLocation="true" allowDefinition="Everywhere"/>
  </configSections>

  <dataCacheClient>
    <transportProperties maxBufferPoolSize="7" maxBufferSize="200000000"/>


    <!-- (optional) specify local cache
      <localCache
         isEnabled="true"
         sync="TimeoutBased"
         objectCount="100000"
         ttlValue="300" /> -->

    <!--(optional) specify cache notifications poll interval
      <clientNotification pollInterval="300" /> -->

    <hosts>
      <host name="10.32.68.136" cachePort="22233"/>
      <!--<host
         name="CacheServer2"
         cachePort="22233"/>-->
    </hosts>
  </dataCacheClient>

Client Code No Config:

           DataCacheFactoryConfiguration cfg= new DataCacheFactoryConfiguration();
            cfg.Servers= new DataCacheServerEndpoint[]
            {
                new DataCacheServerEndpoint("10.32.68.136",22233)//jqdappfabric.dev.gmo.tld",22233)
            };
            Microsoft.ApplicationServer.Caching.DataCacheFactory f = new DataCacheFactory(cfg);
            Console.WriteLine("Factory Created");
            DataCache c=f.GetDefaultCache();
            Console.WriteLine("Cache Connected");
            Console.WriteLine("Put into Cache");
            c.Put("k1","v1");
            Console.WriteLine("Get From Cache");
            Console.WriteLine(c.Get("k1"));

Client Code with Config:

          DataCacheFactory cf = new DataCacheFactory();
            DataCache cache = cf.GetDefaultCache();
            cache.Put("AllEntityHierarchy", list);
            object obj = cache.Get("AllEntityHierarchy");

NOTE: if Visual Studio 2010 Intelle-trace shows "No DNS entry" then use Hosts file.

Some usefull PowShellCommand:

 import/export-CacheClusterConfig: shows/set user permission.
 start/stop-cachecluster
 grant/invoke-CacheAllowedClientAccount

WebSocket Handler

 Separate Open and Message and use Collection to Broadcast
   public class JsonWebSocketHandler : WebSocketHandler
    {

        WebSocketCollection _wsCns = new WebSocketCollection();
        public override void OnMessage(string message)
        {
            JavaScriptSerializer ser = new JavaScriptSerializer();
            _wsCns.Broadcast(ser.Serialize( new
                {
                    data="Test",
                    id=1
                }));
        }

        public override void OnOpen()
        {
            _wsCns.Add(this);
        }
    }

IHttpHandler can inject WebSocketHanldler (Extension Method for Context)

     public void ProcessRequest(HttpContext context)
        {
            if (context.IsWebSocketRequest)
            {
                context.AcceptWebSocketRequest(new JsonWebSocketHandler());
            }
        }

JavaScript also need to separate Open and Send

    $(function () {
        var cn = new WebSocket("ws://localhost/TestJsonWebSocket/jswsh.ashx");
        $("#b").click( function () 
        {
            cn.onmessage = function (msg) {
                alert(msg);
            }
        });

        $("#b2").click(function () {
            cn.send(window.JSON.stringify({ type: 1 }));
            }
        );
        
    });

Websocket asp.net fx4.5

(1) Need to turn on IIS features, Fx 4.5 and WebScoket from Control Panel
(2) Currently must run ASP.Net project in IIS 8.0. So project config must uncheck IIS express. May also need to clean up applicationHost.Config to clear all site/project pointing to port 80.

Make a httpHandler

        public void ProcessRequest(HttpContext ctx)
        {
           
            if (ctx.IsWebSocketRequest)
            {
                Microsoft.Web.WebSockets.WebSocketExtensions.AcceptWebSocketRequest(ctx, new Class1());
              //  ctx.AcceptWebSocketRequest(Test);
            }
            else
            {
                ctx.Response.StatusCode = 400;
            }
        }

        async Task Test(AspNetWebSocketContext wsCtx)
        {
            AspNetWebSocket ws = wsCtx.WebSocket as AspNetWebSocket;
            string UserMsg = "Test from WS";
            WebSocketHandler wsH = new WebSocketHandler();
            wsH.WebSocketContext = wsCtx;
            ArraySegment arrS = new ArraySegment(Encoding.UTF8.GetBytes(UserMsg));
            wsH.Send(UserMsg);
            await ws.SendAsync(arrS, System.Net.WebSockets.WebSocketMessageType.Text, true, CancellationToken.None);
        }

   public class Class1: WebSocketHandler
    {
    }
Use JQuery to connect
<
script src="Scripts/jquery-1.7.1.js" ></script>
  <script>
      $(function () {
          $("#b").click(function () {
             
              var conn = new WebSocket("ws://localhost/TestWebSocket2/test.ashx");

              conn.onmessage = function (msg) {
                  alert(msg.data);
              }
          });
      });
</script>

</asp:Content>
<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">
  <input type="button"  value="Connect to WS" id="b" />

Both JQuery and WebSocket can be downloaded from NuGet

WinRT Code

WinRT component in C# -- public type must be WinRT types
=========================
public sealed class Class1
{
public IList Test()
{
return new List();
}

public IAsyncOperation Test4() //WinRT type
{
return AsyncInfoFactory.Create( ()=>Test2());
}
private async Task Test2()
{
var v = new HttpClient();
var q = await v.GetAsync("");
string s="";
return s;
}
}


Storaage File RO collection
=================================
RO Collection <==> Windows.Foundation.Collections.IVectorView

async void Test()
{
var picker = new FileOpenPicker();
picker.FileTypeFilter.Add("*");
var files = await picker.PickMultipleFilesAsync();
foreach (StorageFile f in files)
{
lb.Items.Add(f.Name);
}
}


Camera from C# ( no more Win32)
==================================

async void camera()
{
var ui = new CameraCaptureUI();
ui.PhotoSettings.CroppedAspectRatio = new Size(4, 3);
var file = await ui.CaptureFileAsync(CameraCaptureUIMode.Photo);
if (file != null)
{
var bitmap = new BitmapImage();
bitmap.SetSource(await file.OpenAsync(FileAccessMode.Read));
}

}
