  • Android ListView: getTag() returns null

    - by TianDong
    Hallo all, I have a ListView which contains a Button in each line. The following code is part of the getView() Method public View getView(final int position, View convertView, ViewGroup parent) { View row = convertView; TextView tv; Button saveA_button; EditText edittext; FITB_ViewWrapper wrapper; if (row == null) { LayoutInflater li = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE); if (ChooseMode_Act.modeInfo.equalsIgnoreCase("Training")) { row = li.inflate(R.layout.exercise_for_training_fitb,parent, false); }else { row = li.inflate(R.layout.exercise_for_exam_fitb,parent, false); } wrapper=new FITB_ViewWrapper(row); row.setTag(wrapper); if (ChooseMode_Act.modeInfo.equalsIgnoreCase("Exam")) { saveA_button=wrapper.getSaveAnswer_Button(); OnClickListener l=new OnClickListener() { @Override public void onClick(View v) { Integer mp=(Integer)v.getTag(); Log.i("mp","my Position is: "+mp); } }; saveA_button.setOnClickListener(l); } }else { wrapper=(FITB_ViewWrapper) row.getTag(); } For my App i need to known to which item the Button belongs to, so i try to detect it. The code Log.i("mp","my Position is: "+mp); puts out a message: mp myPosition is: null I can't understand, why do i get a "null" but not an Integer? How can i find out the Position of an Item in a ListView? Thanks a lot.

  • ConcurrentDictionary and updating values

    - by rboarman
    Hello, After searching via Google and coming up empty, I decided to ask the gurus here on StackOverflow. I am trying to update entries in a ConcurrentDictionary something like this: class Class1 { public int Counter { get; set; } } class Test { private ConcurrentDictionary<int, Class1> dict = new ConcurrentDictionary<int, Class1>(); public void TestIt() { foreach (var foo in dict) { foo.Value.Counter = foo.Value.Counter + 1; // Simplified example } } } Essentially I need to iterate over the dictionary and update a field on each Value. I understand from the documentation that I need to avoid using the Value property. Instead I think I need to use TryUpdate except that I don’t want to replace my whole object. Instead, I want to update a field on the object. After reading this: http://blogs.msdn.com/b/pfxteam/archive/2010/01/08/9945809.aspx Perhaps I need to use AddOrUpdate and simply do nothing in the add delegate. Does anyone have any insight as to how to do this? Thank you, Rick

  • CA2000 and disposal of WCF client

    - by Mayo
    There is plenty of information out there concerning WCF clients and the fact that you cannot simply rely on a using statement to dispose of the client. This is because the Close method can throw an exception (i.e. if the server hosting the service doesn't respond). I've done my best to implement something that adheres to the numerous suggestions out there. public void DoSomething() { MyServiceClient client = new MyServiceClient(); // from service reference try { client.DoSomething(); } finally { client.CloseProxy(); } } public static void CloseProxy(this ICommunicationObject proxy) { if (proxy == null) return; try { if (proxy.State != CommunicationState.Closed && proxy.State != CommunicationState.Faulted) { proxy.Close(); } else { proxy.Abort(); } } catch (CommunicationException) { proxy.Abort(); } catch (TimeoutException) { proxy.Abort(); } catch { proxy.Abort(); throw; } } This appears to be working as intended. However, when I run Code Analysis in Visual Studio 2010 I still get a CA2000 warning. CA2000 : Microsoft.Reliability : In method 'DoSomething()', call System.IDisposable.Dispose on object 'client' before all references to it are out of scope. Is there something I can do to my code to get rid of the warning or should I use SuppressMessage to hide this warning once I am comfortable that I am doing everything possible to be sure the client is disposed of? Related resources that I've found: http://www.theroks.com/2011/03/04/wcf-dispose-problem-with-using-statement/ http://www.codeproject.com/Articles/151755/Correct-WCF-Client-Proxy-Closing.aspx http://codeguru.earthweb.com/csharp/.net/net_general/tipstricks/article.php/c15941/

  • Box2d: Set active and inactive

    - by Rosarch
    I'm writing an XNA game in C# using the XNA port of Box2d - Box2dx. Entities like trees or zombies are represented as GameObjects. GameObjectManager adds and removes them from the game world: /// <summary> /// Does the work of removing the GameObject. /// </summary> /// <param name="controller">The GameObject to be removed.</param> private void removeGameObjectFromWorld(GameObjectController controller) { controllers.Remove(controller); worldState.Models.Remove(controller.Model); controller.Model.Body.SetActive(false); } public void addGameObjectToWorld(GameObjectController controller) { controllers.Add(controller); worldState.Models.Add(controller.Model); controller.Model.Body.SetActive(true); } controllers is a collection of GameObjectController instances. worldState.Models is a collection of GameObjectModel instances. When I remove GameObjects from Box2d this way, this method gets called: void IContactListener.EndContact(Contact contact) { GameObjectController collider1 = worldQueryUtils.gameObjectOfBody(contact.GetFixtureA().GetBody()); GameObjectController collider2 = worldQueryUtils.gameObjectOfBody(contact.GetFixtureB().GetBody()); collisionRecorder.removeCollision(collider1, collider2); } worldQueryUtils: // this could be cached if we know bodies never change public GameObjectController gameObjectOfBody(Body body) { return worldQueryEngine.GameObjectsForPredicate(x => x.Model.Body == body).Single(); } This method throws an error: System.InvalidOperationException was unhandled Message="Sequence contains no elements" Source="System.Core" StackTrace: at System.Linq.Enumerable.Single[TSource](IEnumerable`1 source) at etc Why is this happening? What can I do to avoid it? This method has been called many times before the body.SetActive() was called. I feel that this may be messing it up.

  • JavaScriptSerializer().Serialize(Entity Framework object)

    - by loviji
    May be, it is not so problematic for you. but i'm trying first time with json serialization. and also read other articles in stackowerflow. I have created Entity Framework data model. then by method get all data from object: private uqsEntities _db = new uqsEntities(); //get all data from table sysMainTableColumns where tableName=paramtableName public List<sysMainTableColumns> getDataAboutMainTable(string tableName) { return (from column in _db.sysMainTableColumns where column.TableName==tableName select column).ToList(); } my webservice: public string getDataAboutMainTable() { penta.DAC.Tables dictTable = new penta.DAC.Tables(); var result = dictTable.getDataAboutMainTable("1"); return new JavaScriptSerializer().Serialize(result); } and jQuery ajax method $('#loadData').click(function() { $.ajax({ type: "POST", url: "WS/ConstructorWS.asmx/getDataAboutMainTable", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { $("#jsonResponse").html(msg); var data = eval("(" + msg + ")"); //do something with data }, error: function(msg) { } }); }); problem with data, code fails there. and i think i'm not use JavaScriptSerializer().Serialize() method very well. Please, tell me, what a big mistake I made in C# code?

  • JSF 2.0 AJAX: jsf.ajax.request to call method not only rerender an area of page

    - by gerry
    Hi, I'm looking for a soultion of the following problem: _The is a list of links with different types of cars. _The user can click on each car in the list and a ajax request should be sent. _The response of the ajax request should be dependent on the id (of each car) and displayed in an panelGroup. So what I need is a possibility to call a method on the backing-bean. Additionally, this method should be called with a car id as its parameter. My code so far looks like: ... <ul> <ui:repeat value="#{carTree.getCars)}" var="car"> <h:outputScript name="jsf.js" library="javax.faces" target="head" /> <li onclick="showDetails(#{car.id});">#{car.name}</li> </ui:repeat> </ul> ... <h:panelGroup id="carDetails" layout="block" style="float:left;"> // need the details of each 'selected /clicked' car here </h:panelGroup> ...

  • How to bind collection to WPF:DataGridComboBoxColumn

    - by everwicked
    Admittedly I am new to WPF but I have looked and looked and can't find a solution to this problem. I have a simple object like: class Item { .... public String Measure { get; set; } public String[] Measures {get; } } Which I am trying to bind to a DataGrid with two text columns and a combo box column. For the combo box column, propery Measure is the current selection and Measures the possible values. My XAML is: <DataGridComboBoxColumn Header="Measure" Width="Auto" SelectedItemBinding="{Binding Path=Measure}" ItemsSource="{Binding Path=Measures}"/> </DataGrid.Columns> </DataGrid> The text column are displayed just fine but the combobox is not - the values are not displayed at all. The binding error is : ¨System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Measures; DataItem=null; target element is 'DataGridComboBoxColumn' (HashCode=11497055); target property is 'ItemsSource' (type 'IEnumerable') How do I fix this??? Thanks

  • Java: immutable Stack?

    - by HH
    I chose to use Stacks and Tables before knowing Collections has immutable empty things only for Set, Map and List. Because the size of table does not change after its init: Integer[] table = new Intger[0] I can use the zero-witdh table as an empty table. But I cannot use final or empty Stack to get immutable Stack: No immutability to Stack with Final import java.io.*; import java.util.*; public class TestStack{ public static void main(String[] args) { final Stack<Integer> test = new Stack<Integer>(); Stack<Integer> test2 = new Stack<Integer>(); test.push(37707); test2.push(80437707); //WHY is there not an error to remove an elment // from FINAL stack? System.out.println(test.pop()); System.out.println(test2.pop()); } } Java Api 5 for list interface shows that Stack is an implementing class for list and arraylist, here. The java.coccurrent pkg does not have any immutable Stack data structure. From Stack to some immutable data structure How to get immutable Stack data structure? Can I box it with list? Should I switch my current implementatios from stacks to Lists to get immutable? Which immutable data structure is Very fast with about similar exec time as Stack?

  • Is this a good implementation of DefaultHttpClient and ThreadSafeClientConnManager in Android?

    - by johnrock
    In my Android app I am sharing one httpclient for all activities/threads. All requests are made by callling getHttpClient().execute(httpget) or getHttpClient().execute(httppost). Is this implementation complete/correct and safe for multiple threads? Is there anything else missing i.e. Do I have to worry about releasing connections at all? private static HttpClient httpclient ; public static HttpClient getHttpClient() { if(httpclient == null){ return getHttpClientNew(); } else{ return httpclient; } } public static synchronized HttpClient getHttpClientNew() { HttpParams params = new BasicHttpParams(); ConnManagerParams.setMaxTotalConnections(params, 100); HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1); HttpProtocolParams.setContentCharset(params, "UTF_8"); HttpProtocolParams.setUseExpectContinue(params, false); HttpConnectionParams.setConnectionTimeout(params, 10000); HttpConnectionParams.setSoTimeout(params, 10000); SchemeRegistry schemeRegistry = new SchemeRegistry(); schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80)); ClientConnectionManager cm = new ThreadSafeClientConnManager(params, schemeRegistry); httpclient = new DefaultHttpClient(cm, params); return httpclient; } This is an example of how the httpclient is used: private void update() { HttpGet httpget = new HttpGet(URL); httpget.setHeader(USER_AGENT, userAgent); httpget.setHeader(CONTENT_TYPE, MGUtils.APP_XML); HttpResponse response; try { response = getHttpClient().execute(httpget); HttpEntity entity = response.getEntity(); if (entity != null) { // parse stuff } } catch (Exception e) { } }

  • Greyscale Image from YUV420p data

    - by fergs
    From what I have read on the internet the Y value is the luminance value and can be used to create a grey scale image.

I have the current piece of code and it is failing on Marshal.Copy – attempted to read or write protected memory. public Bitmap ConvertToGrayscale2(byte[] yuvData, int width, int height) { Bitmap bmp; IntPtr blue = IntPtr.Zero; int inputOffSet = 0; long[] pixels = new long[width * height]; try { for (int y = 0; y < height; y++) { int outputOffSet = y * width; for (int x = 0; x < width; x++) { int grey = yuvData[inputOffSet + x] & 0xff; unchecked { pixels[outputOffSet + x] = UINT_Constant | (grey * INT_Constant); } } inputOffSet += width; } blue = Marshal.AllocCoTaskMem(pixels.Length); Marshal.Copy(pixels, 0, blue, pixels.Length); // fails here : Attempted to read or write protected memory bmp = new Bitmap(width, height, width, PixelFormat.Format24bppRgb, blue); } catch (Exception) { throw; } finally { if (blue != IntPtr.Zero) { Marshal.FreeHGlobal(blue); blue = IntPtr.Zero; } } return bmp; } Any help would be appreciated?

  • Selectively suppress XML Code Comments in C#?

    - by Mike Post
    We deliver a number of assemblies to external customers, but not all of the public APIs are officially supported. For example, due to less than optimal design choices sometimes a type must be publicly exposed from an assembly for the rest of our code to work, but we don't want customers to use that type. One part of communicating the lack of support is not provide any intellisense in the form of XML comments. Is there a way to selectively suppress XML comments? I'm looking for something other than ignoring warning 1591 since it's a long term maintenance issue. Example: I have an assembly with public classes A and B. A is officially supported and should have XML documentation. B is not intended for external use and should not be documented. I could turn on XML documentation and then suppress warning 1591. But when I later add the officially supported class C, I want the compiler to tell me that I've screwed up and failed to add the XML documentation. This wouldn't occur if I had suppressed 1591 at the project level. I suppose I could #pragma across entire classes, but it seems like there should be a better way to do this.

  • axis2 web service behave differently when tested with web service client or with local test class

    - by Stefano
    Hello I need to update a facade to some web service proxy classes to a third party web service, and expose them as a service. This for two reason : to maintain the same interface for all application that need to use the system : actually its migrating and there are a few differences in the third party ws (method names); and to expose a simplified interface. The third party has provided me with a manual and some pregenerated proxy classes to their service (the java file says generated with axis2 1,4) . I've used netbeans 6.8 and the axis2 plugin to create an axis2 service . This service contains the proxy classes and the facade class which instantiate the web service proxy and calls its method; the facade class is exposed as service. I've used axis2 1.4 (at beginnig and later 1.5 ) and tomcat 6.0. The first test i did was to call the facede methods from inside the project itself and it worked. Then i've created a new project with a jax-ws web service client to call my class deployed on axis2. At this point has happened two strange thing : In the axis2 services page has appeared the third party proxy class as if it were a new service (if i try to get the wsdl axis raises an error ). eg. the proxy interface is named WebServiceAPI (_stub is the concrete class) and , after the first call to my service , i find a new "WebServicesAPI1272968932531_1" service inside axis . The call obvoiusly fail i've began to sniff soap messages with wireshark and i've found they differs when using proxy classes direclty from my facade test class by the messages created after being deployed on axis. i've noticed they differs for the presence of the soap header in the failing message. any help would be greatly appreciated : maybe i messed up something, there might be some incompatibilities or version mistakes? below i've added the signature of the third party proxy, its impementation and the different soap messages: /* * WebServicesAPI.java * This file was auto-generated from WSDL * by the Apache Axis2 version: 1.4 Built on : Apr 26, 2008 (06:24:30 EDT) */ package com.ibm.eci.wsapi;

  • How do I properly host a WCF Data Service in IIS? Why am I getting errors?

    - by j0rd4n
    I'm playing around with WCF Data Services (ADO.NET Data Services). I have an entity framework model pointed at the AdventureWorks database. When I debug my svc file from within Visual Studio, it works great. I can say /awservice.svc/Customers and get back the ATOM feed I expect. If I publish the service (hosted in an ASP.NET web application) to IIS7, the same query string returns a 500 fault. The root svc page itself works as expected and successfully returns ATOM. The /Customers path fails. Here is what my grants look like in the svc file: public class AWService : DataService<AWEntities> { public static void InitializeService( DataServiceConfiguration config ) { config.SetEntitySetAccessRule( "*", EntitySetRights.All ); config.SetServiceOperationAccessRule( "*", ServiceOperationRights.All ); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } } Update: I enabled verbose errors and get the following in the XML message: <innererror> <message>The underlying provider failed on Open.</message> <type>System.Data.EntityException</type> <stacktrace> at System.Data.EntityClient.EntityConnection.OpenStoreConnectionIf( ... ... <internalexception> <message> Login failed for user 'IIS APPPOOL\DefaultAppPool'. </message> <type>System.Data.SqlClient.SqlException</type> <stacktrace> at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, ...

  • Retrieve enum value based on XmlEnumAttribute name value

    - by CletusLoomis
    I need a Generic function to retrieve the name or value of an enum based on the XmlEnumAttribute "Name" property of the enum. For example I have the following enum defined: Public Enum Currency <XmlEnum("00")> CDN = 1 <XmlEnum("01")> USA= 2 <XmlEnum("02")> EUR= 3 <XmlEnum("03")> JPN= 4 End Enum The first Currency enum value is 1; the enum name is "CDN"; and the XMLEnumAttribute Name property value is "00". If I have the enum value, I can retrieve the XmlEnumAttribute "Name" value using the following generic function: Public Function GetXmlAttrNameFromEnumValue(Of T)(ByVal pEnumVal As T) As String Dim type As Type = pEnumVal.GetType Dim info As FieldInfo = type.GetField([Enum].GetName(GetType(T), pEnumVal)) Dim att As XmlEnumAttribute = CType(info.GetCustomAttributes(GetType(XmlEnumAttribute), False)(0), XmlEnumAttribute) 'If there is an xmlattribute defined, return the name Return att.Name End Function So using the above function, I can specify the Currency enum type, pass a value of 1, and the return value will be "00". What I need is a function to perform if the opposite. If I have the XmlEnumAttribute Name value "00", I need a function to return a Currency enum with a value of 1. Just as useful would be a function that would return the enum name "CDN". I could then simply parse this to get the enum value. Any assistance would be appreciated.

  • How to convert an NSString to hex values

    - by einsteinx2
    I'd like to convert a regular NSString into an NSString with the (what I assume are) ASCII hex values and back. I need to produce the same output that the Java methods below do, but I can't seem to find a way to do it in Objective-C. I've found some examples in C and C++ but I've had a hard time working them into my code. Here are the Java methods I'm trying to reproduce: /** * Encodes the given string by using the hexadecimal representation of its UTF-8 bytes. * * @param s The string to encode. * @return The encoded string. */ public static String utf8HexEncode(String s) { if (s == null) { return null; } byte[] utf8; try { utf8 = s.getBytes(ENCODING_UTF8); } catch (UnsupportedEncodingException x) { throw new RuntimeException(x); } return String.valueOf(Hex.encodeHex(utf8)); } /** * Decodes the given string by using the hexadecimal representation of its UTF-8 bytes. * * @param s The string to decode. * @return The decoded string. * @throws Exception If an error occurs. */ public static String utf8HexDecode(String s) throws Exception { if (s == null) { return null; } return new String(Hex.decodeHex(s.toCharArray()), ENCODING_UTF8); }

  • How to create a MVC 2 DisplayTemplate for a field whose display format is dependent on another field

    - by Glenn
    If I have a property whose display format is dependent on the value of another property in the view model how do I create a display template for it? The combination of field1's display being dependent on field2's value will be used throughout the app and I would like to encapsulate this in a MVC 2 display template. To be more specific, I've already create a display template (Social.ascx) for custom data type Social that masks a social security number for display. For instance, XXX-XX-1234. [DataType("Social")] public string SocialSecurityNumber { get; set; } All employees also have an employeeID. Certain companies use the employee's social security number as either the whole employee id or as part of it. I need to also mask the employeeID if it contains the social. I'd like to create another display template (EmpID.ascx) to perform this task. [DataType("EmpID")] public string EmployeeID { get; set; } The problem is that I don't know how to get both properties in the "EmpID" template to be able to perform the comparison. Thanks for the help.
