• How can I configure a Factory with the possible providers?

  - by Jonathas Costa

  I have three assemblies: "Framework.DataAccess", "Framework.DataAccess.NHibernateProvider" and "Company.DataAccess". Inside the assembly "Framework.DataAccess", I have my factory (with the wrong implementation of discovery): public class DaoFactory { private static readonly object locker = new object(); private static IWindsorContainer _daoContainer; protected static IWindsorContainer DaoContainer { get { if (_daoContainer == null) { lock (locker) { if (_daoContainer != null) return _daoContainer; _daoContainer = new WindsorContainer(new XmlInterpreter()); // THIS IS WRONG! THIS ASSEMBLY CANNOT KNOW ABOUT SPECIALIZATIONS! _daoContainer.Register( AllTypes.FromAssemblyNamed("Company.DataAccess") .BasedOn(typeof(IReadDao<>)).WithService.FromInterface(), AllTypes.FromAssemblyNamed("Framework.DataAccess.NHibernateProvider") .BasedOn(typeof(IReadDao<>)).WithService.Base()); } } return _daoContainer; } } public static T Create<T>() where T : IDao { return DaoContainer.Resolve<T>(); } } This assembly also defines the base interface for data access IReadDao: public interface IReadDao<T> { IEnumerable<T> GetAll(); } I want to keep this assembly generic and with no references. This is my base data access assembly. Then I have the NHibernate provider's assembly, which implements the above IReadDao using NHibernate's approach. This assembly references the "Framework.DataAccess" assembly. public class NHibernateDao<T> : IReadDao<T> { public NHibernateDao() { } public virtual IEnumerable<T> GetAll() { throw new NotImplementedException(); } } At last, I have the "Company.DataAccess" assembly, which can override the default implementation of NHibernate provider and references both previously seen assemblies. public interface IProductDao : IReadDao<Product> { Product GetByName(string name); } public class ProductDao : NHibernateDao<Product>, IProductDao { public override IEnumerable<Product> GetAll() { throw new NotImplementedException("new one!"); } public Product GetByName(string name) { throw new NotImplementedException(); } } I want to be able to write... IRead<Product> dao = DaoFactory.Create<IRead<Product>>(); ... and then get the ProductDao implementation. But I can't hold inside my base data access any reference to specific assemblies! My initial idea was to read that from a xml config file. So, my question is: How can I externally configure this factory to use a specific provider as my default implementation and my client implementation?

• In an extension method how do a create an object based on the implementation class

  - by Greg

  Hi, In an extension method how do a create an object based on the implementation class. So in the code below I wanted to add an "AddRelationship" extension method, however I'm not sure how within the extension method I can create an Relationship object? i.e. don't want to tie the extension method to this particular implementation of relationship public static class TopologyExtns { public static void AddNode<T>(this ITopology<T> topIf, INode<T> node) { topIf.Nodes.Add(node.Key, node); } public static INode<T> FindNode<T>(this ITopology<T> topIf, T searchKey) { return topIf.Nodes[searchKey]; } public static bool AddRelationship<T>(this ITopology<T> topIf, INode<T> parentNode, INode<T> childNode) { var rel = new RelationshipImp(); // ** How do I create an object from teh implementation // Add nodes to Relationship // Add relationships to Nodes } } public interface ITopology<T> { //List<INode> Nodes { get; set; } Dictionary<T, INode<T> > Nodes { get; set; } } public interface INode<T> { // Properties List<IRelationship<T>> Relationships { get; set; } T Key { get; } } public interface IRelationship<T> { // Parameters INode<T> Parent { get; set; } INode<T> Child { get; set; } } namespace TopologyLibrary_Client { class RelationshipsImp : IRelationship<string> { public INode<string> Parent { get; set; } public INode<string> Child { get; set; } } } public class TopologyImp<T> : ITopology<T> { public Dictionary<T, INode<T>> Nodes { get; set; } public TopologyImp() { Nodes = new Dictionary<T, INode<T>>(); } } thanks

• What's a clean way to break up a DataTable into chunks of a fixed size with Linq?

  - by Michael Haren

  Update: Here's a similar question Suppose I have a DataTable with a few thousand DataRows in it. I'd like to break up the table into chunks of smaller rows for processing. I thought C#3's improved ability to work with data might help. This is the skeleton I have so far: DataTable Table = GetTonsOfData(); // Chunks should be any IEnumerable<Chunk> type var Chunks = ChunkifyTableIntoSmallerChunksSomehow; // ** help here! ** foreach(var Chunk in Chunks) { // Chunk should be any IEnumerable<DataRow> type ProcessChunk(Chunk); } Any suggestions on what should replace ChunkifyTableIntoSmallerChunksSomehow? I'm really interested in how someone would do this with access C#3 tools. If attempting to apply these tools is inappropriate, please explain! Update 3 (revised chunking as I really want tables, not ienumerables; going with an extension method--thanks Jacob): Final implementation: Extension method to handle the chunking: public static class HarenExtensions { public static IEnumerable<DataTable> Chunkify(this DataTable table, int chunkSize) { for (int i = 0; i < table.Rows.Count; i += chunkSize) { DataTable Chunk = table.Clone(); foreach (DataRow Row in table.Select().Skip(i).Take(chunkSize)) { Chunk.ImportRow(Row); } yield return Chunk; } } } Example consumer of that extension method, with sample output from an ad hoc test: class Program { static void Main(string[] args) { DataTable Table = GetTonsOfData(); foreach (DataTable Chunk in Table.Chunkify(100)) { Console.WriteLine("{0} - {1}", Chunk.Rows[0][0], Chunk.Rows[Chunk.Rows.Count - 1][0]); } Console.ReadLine(); } static DataTable GetTonsOfData() { DataTable Table = new DataTable(); Table.Columns.Add(new DataColumn()); for (int i = 0; i < 1000; i++) { DataRow Row = Table.NewRow(); Row[0] = i; Table.Rows.Add(Row); } return Table; } }

• How can I make the C# compiler infer these type parameters automatically?

  - by John Feminella

  I have some code that looks like the following. First I have some domain classes and some special comparators for them. public class Fruit { public int Calories { get; set; } public string Name { get; set; } } public class FruitEqualityComparer : IEqualityComparer<Fruit> { // ... } public class BasketEqualityComparer : IEqualityComparer<IEnumerable<Fruit>> { // ... } Next, I have a helper class called ConstraintChecker. It has a simple BaseEquals method that makes sure some simple base cases are considered: public static class ConstraintChecker { public static bool BaseEquals(T lhs, T rhs) { bool sameObject = l == r; bool leftNull = l == null; bool rightNull = r == null; return sameObject && !leftNull && !rightNull; } There's also a SemanticEquals method which is just a BaseEquals check and a comparator function that you specify. public static bool SemanticEquals<T>(T lhs, T rhs, Func<T, T, bool> f) { return BaseEquals(lhs, rhs) && f(lhs, rhs); } And finally there's a SemanticSequenceEquals method which accepts two IEnumerable<T> instances to compare, and an IEqualityComparer instance that will get called on each pair of elements in the list via Enumerable.SequenceEquals. public static bool SemanticSequenceEquals<T, U, V>(U lhs, U rhs, V comparator) where U : IEnumerable<T> where V : IEqualityComparer<T> { return SemanticEquals(lhs, rhs, (l, r) => lhs.SequenceEqual(rhs, comparator)); } } // end of ConstraintChecker The point of SemanticSequenceEquals is that you don't have to define two comparators whenever you want to compare both IEnumerable<T> and T instances; now you can just specify an IEqualityComparer<T> and it will also handle lists when you invoke SemanticSequenceEquals. So I could get rid of the BasketEqualityComparer class, which would be nice. But there's a problem. The C# compiler can't figure out the types involved when you invoke SemanticSequenceEquals: return ConstraintChecker.SemanticSequenceEquals(lhs, rhs, new FruitEqualityComparer()); If I specify them explicitly, it works: return ConstraintChecker.SemanticSequenceEquals< Fruit, IEnumerable<Fruit>, IEqualityComparer<Fruit> > (lhs, rhs, new FruitEqualityComparer()); What can I change here so that I don't have to write the type parameters explicitly?

• How to create constant NSString by concatenating strings in Obj-C ?

  - by eric-morand

  Hi guys, I'm trying to instanciate a constant NSString by concatanating other NSString instances. Here is what I'm doing in my implementation file : static NSString *const MY_CONST = @"TEST"; static NSString *const MY_CONCATENATE_CONST = [NSString stringWithFormat:@"STRING %@", MY_CONST]; It leads to the following compilation error : Initializer element is not constant I suppose this is because stringWithFormat doesn't return a constant NSString, but since there is no other way to concatenate strings in Obj-C, what am I supposed to do ? Thanks for your help, Eric.

• What Java syntax elements would not directly translate to an equivalent Ruby syntax?

  - by Hosh

  I asked a question a few days ago about representing public static final and private static final fields in equivalent Ruby code. It got me thinking about what other syntax elements in Java might not translate directly to Ruby. Generics and Annotations come to mind. Anything else that would not translate well if you tried to port some Java code to Ruby?

• What am I missing in this ASP.NET XSS Security Helper class?

  - by smartcaveman

  I need a generic method for preventing XSS attacks in ASP.NET. The approach I came up with is a ValidateRequest method that evaluates the HttpRequest for any potential issues, and if issues are found, redirect the user to the same page, but in a away that is not threatening to the application. (Source code below) While I know this method will prevent most XSS attacks, I am not certain that I am adequately preventing all possible attacks while also minimizing false positives. So, what is the most effective way to adequately prevent all possible attacks, while minimizing false positives? Are there changes I should make to the helper class below, or is there an alternative approach or third party library that offers something more convincing? public static class XssSecurity { public const string PotentialXssAttackExpression = "(http(s)*(%3a|:))|(ftp(s)*(%3a|:))|(javascript)|(alert)|(((\\%3C) <)[^\n]+((\\%3E) >))"; private static readonly Regex PotentialXssAttackRegex = new Regex(PotentialXssAttackExpression, RegexOptions.IgnoreCase); public static bool IsPotentialXssAttack(this HttpRequest request) { if(request != null) { string query = request.QueryString.ToString(); if(!string.IsNullOrEmpty(query) && PotentialXssAttackRegex.IsMatch(query)) return true; if(request.HttpMethod.Equals("post", StringComparison.InvariantCultureIgnoreCase)) { string form = request.Form.ToString(); if (!string.IsNullOrEmpty(form) && PotentialXssAttackRegex.IsMatch(form)) return true; } if(request.Cookies.Count > 0) { foreach(HttpCookie cookie in request.Cookies) { if(PotentialXssAttackRegex.IsMatch(cookie.Value)) { return true; } } } } return false; } public static void ValidateRequest(this HttpContext context, string redirectToPath = null) { if(context == null || !context.Request.IsPotentialXssAttack()) return; // expire all cookies foreach(HttpCookie cookie in context.Request.Cookies) { cookie.Expires = DateTime.Now.Subtract(TimeSpan.FromDays(1)); context.Response.Cookies.Set(cookie); } // redirect to safe path bool redirected = false; if(redirectToPath != null) { try { context.Response.Redirect(redirectToPath,true); redirected = true; } catch { redirected = false; } } if (redirected) return; string safeUrl = context.Request.Url.AbsolutePath.Replace(context.Request.Url.Query, string.Empty); context.Response.Redirect(safeUrl,true); } }

• C array initialization.

  - by chrisdew

  Why does static char *opcode_str[] = { "DATA" , "DATA_REQUEST_ACK" , "ACK_TIMER_EXPIRED" , "ACK_UNEXPECTED_SEQ" , "ACK_AS_REQUESTED" } ; work, but static char **opcode_str = { "DATA" , "DATA_REQUEST_ACK" , "ACK_TIMER_EXPIRED" , "ACK_UNEXPECTED_SEQ" , "ACK_AS_REQUESTED" } ; fails with SEGV when opcode_str[0] is printf'd? I think it's because the second listing has not allocated memory for the five element array of pointers, but I need a more comprehensive explanation. All the best, Chris.

• RemoteViewsService never gets called whenever we update app widget

  - by user3689160

  I am making one task widget application. This is a simple widget application which can be used to add new tasks by clicking on "+New Task". So ideally what I have done is, I've added a widget first, then when we click on "+New Task" a new activity opens up from where we can type in a new task and it should get updated in the ListView inside the home screen widget. Problem: Now whenever I add a new task, the ListView does not get updated. The data gets inside the database a new is created as well. My onUpdate(...) method gets called as well. There is a WidgetService.java which is a RemoteViewService that is being used to call the RemoteViewFactory but WidgetService.java gets called only when we create the widget, never after that. WidgetService.java never gets called again. I have the following setup MyWidgetProvider.java AppWidgetProvider class for updating the widget and filling its remote views. public class MyWidgetProvider extends AppWidgetProvider { public static int randomNumber=132; static RemoteViews remoteViews = null; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { updateList(context,appWidgetManager,appWidgetIds); } public static void updateList(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){ final int N = appWidgetIds.length; Log.d("MyWidgetProvider", "length="+appWidgetIds.length+""); for (int i = 0; i<N; ++i) { Log.d("MyWidgetProvider", "value"+ i + "="+appWidgetIds[i]); // Calling updateWidgetListView(context, appWidgetIds[i]); to load the listview with data remoteViews = updateWidgetListView(context, appWidgetIds[i]); // Updating the Widget with the new data filled remoteviews appWidgetManager.updateAppWidget(appWidgetIds[i], remoteViews); appWidgetManager.notifyAppWidgetViewDataChanged(appWidgetIds[i], R.id.lv_tasks); } } private static RemoteViews updateWidgetListView(Context context, int appWidgetId) { Intent svcIntent = null; remoteViews = new RemoteViews(context.getPackageName(),R.layout.widget_demo);

• Java: file write on finalize method

  - by sowrov

  In my understanding a singleton object will destroy only when the application is about to terminate. So in C++ I write a Singleton class to log my application and in that Singleton logger's destructor I log the time when my application was terminated. Things worked perfectly in C++. Now I want to have that same logger in Java, as in java there is no destructor so I implemented the finalize method for that singleton logger. But it seem that finalize method actually never get called. So, I add that System.runFinalizersOnExit(true); line, somewhere in my code (though I know it is deprecated) and that finalize method get called every time before termination of the app. But still there is a problem! If I try to write anything on file in that finalize method, It does not work, though System.out work without any problem! :( Can you guys help me on this problem? Here is a sample code of what I am try to do: Singleton Logger Class: public class MyLogger { FileWriter writer; private MyLogger() { try { this.writer = new FileWriter("log.txt"); } catch (IOException ex) { } } public static MyLogger getInstance() { return MyLoggerHolder.INSTANCE; } private static class MyLoggerHolder { private static final MyLogger INSTANCE = new MyLogger(); } @Override protected void finalize () { try { super.finalize(); System.out.println("Here"); //worked correctly. this.writer.write(new Date().toString()+System.getProperty("line.separator")); this.writer.write("End"); this.writer.flush(); //does not work! this.writer.close(); } catch (Throwable ex) { } } public synchronized void log(String str) { try { this.writer.write(new Date().toString()+System.getProperty("line.separator")); this.writer.write(str+"\n"); this.writer.flush(); } catch (IOException ex) { } } } Main: public class Main { public static void main(String[] args) { System.runFinalizersOnExit(true); MyLogger logger = MyLogger.getInstance(); logger.log("test"); } }

• Java Log ==> JTextArea

  - by asmo

  Need: Output a Java application's log into a GUI component, such as a JTextArea. Concern: Need to log things from any class, in a static manner. However, the GUI logger component must not be static (obviously) as it's the member of a parent component. What should I do?
