• How can a Delphi TForm / TPersistent object calculate its own deserialization time?

  - by mjustin

  For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions.

• how to get the value of a kendoui dropdown list selected value in a listview

  - by user1568738

  am having Some kendoui listviews which consists of kendoui dropdown lists and i want to get those dropdown list selected values. To do this am trying, $("#cnty1").val(); and here is my dropdownlist,i.e., list of countries coming from Database table, <input select STYLE="width:90px;height:auto" id ="cnty1" data-bind="value:cnty1" name="cnty1" data-type="string" data-text-field="cnty" data-value-field="cntyid" data-source="sourcedata1" class="k-d" data-role="dropdownlist" /> <span data-for="cnty1" class="k-invalid-msg"></span> here cnty1 is the id of the dropdown list, but am not getting the value instead am getting "id" of the slected value but not the selected value. And also if the value is not selected am getting the first value id by using $("#cnty1").val(); So, please suggest me a solution so that, 1) I should get only the Selected value and 2) Value of the dropdown list Only if the user selects a value from the list, but don't get the value of the list without selecting.

• OBJ-C: Call an instance of core-plot graph from separate view controller

  - by Kevin

  I'm using a view controller i.e. ViewController:UIViewController and have another class GraphViewController:UIViewController . How do I call an instance of GraphViewController and place it into my ViewController? I am currently trying to call the plot within my ViewController directly, but I want to make the graph modular so I don't have to copy code if I use the same graph again. ViewController has methods -(void) refreshGraph; //Inhereted Methods -(NSUInteger)numberOfRecordsForPlot:(CPPlot *)plot; -(NSNumber *)numberForPlot:(CPPlot *)plot field:(NSUInteger)fieldEnum recordIndex:(NSUInteger)index; How do I move these methods to a separate class and then call it to get the same plot in my ViewController? I am sure there must be a thread on this somewhere but I can't seem to find it.

• What's the convention for extending Linq datacontext with set based helper operations specific to on

  - by Luke Rohde

  Hi All I might be vaguing out here but I'm looking for a nice place to put set based helper operations in linq so I can do things like; db.Selections.ClearTemporary() which does something like db.DeleteAllOnSubmit(db.Selections.Where(s => s.Temporary)) Since I can figure out how to extend Table<Selection> the best I can do is create a static method in partial class of Selection (similar to Ruby) but I have to pass in the datacontext like; Selection.ClearTemporary(MyDataContext) This kind of sucks because I have two conventions for doing set based operations and I have to pass the data context to the static class. I've seen other people recommending piling helper methods into a partial of the datacontext like; myDataContext.ClearTemporarySelections(); But I feel this makes the dc a dumping ground for in-cohesive operations. Surely I'm missing something. I hope so. What's the convention? TIA

• Should I match the curly brace usage of the previous author?

  - by Error 454

  When working on code from multiple authors, I often encounter the issue of curly-brace preference (same line vs new line). Is it good/bad practice or even a non-issue when it comes to matching the existing style vs using your own preference? Does the situation change if you are adding new code to a Class vs modifying existing code? Finally, if style should be matched, how far should the match propagate? i.e. the file, the class, subclasses etc. Example: if(this) { doThat(); } Vs. if(this){ doThat(); }

• Backbone.Marionette - Collection within CompositeView, which itself is nested in a CollectionView

  - by nicefinly

  *UPDATE: The problem probably involves the tour-template as I've discovered that it thinks the 'name' attribute is undefined. This leads me to think that it's not an array being passed on to the ToursView, but for some reason a string. * After studying similar questions on StackOverflow: How to handle nested CompositeView using Backbone.Marionette? How do you properly display a Backbone marionette collection view based on a model javascript array property? Nested collections with Backbone.Marionette ... and Derick Bailey's excellent blog's on this subject: http://lostechies.com/derickbailey/2012/04/05/composite-views-tree-structures-tables-and-more/ ... including the JSFiddle's: http://jsfiddle.net/derickbailey/AdWjU/ I'm still having trouble with a displaying the last node of a nested CollectionView of CompositeViews. It is the final CollectionView within each CompositeView that is causing the problem. CollectionView { CompositeView{ CollectionView {} //**<-- This is the troublemaker!** } } NOTE: I have already made a point of creating a valid Backbone.Collection given that the collection passed on to the final, child CollectionView is just a simple array. Data returned from the api to ToursList: [ { "id": "1", "name": "Venice", "theTours": "[ {'name': u'test venice'}, {'name': u'test venice 2'} ]" }, { "id": "2", "name": "Rome", "theTours": "[ {'name': u'Test rome'} ]" }, { "id": "3", "name": "Dublin", "theTours": "[ {'name': u'test dublin'}, {'name': u'test dublin 2'} ]" } ] I'm trying to nest these in a dropdown where the nav header is the 'name' (i.e. Dublin), and the subsequent li 's are the individual tour names (i.e. 'test dublin', 'test dublin2', etc.) Tour Models and Collections ToursByLoc = TastypieModel.extend({}); ToursList = TastypieCollection.extend({ model: ToursByLoc, url:'/api/v1/location/', }); Tour Views ToursView = Backbone.Marionette.ItemView.extend({ template: '#tour-template', tagName: 'li', }); ToursByLocView = Backbone.Marionette.CompositeView.extend({ template: '#toursByLoc-template', itemView: ToursView, initialize: function(){ //As per Derick Bailey's comments regarding the need to pass on a //valid Backbone.Collection to the child CollectionView //REFERENCE: http://stackoverflow.com/questions/12163118/nested-collections-with-backbone-marionette var theTours = this.model.get('theTours'); this.collection = new Backbone.Collection(theTours); }, appendHtml: function(collectionView, itemView){ collectionView.$('div').append(itemView.el); } }); ToursListView = Backbone.Marionette.CollectionView.extend({ itemView: ToursByLocView, }); Templates <script id="tour-template" type="text/template"> <%= name %> </script> <script id="toursByLoc-template" type="text/template"> <li class="nav-header"><%= name %></li> <div class="indTours"></div> <li class="divider"></li> </script>

• Invoke "internal extern" constructor using reflections

  Hi, I have following class (as seen through reflector) public class W : IDisposable { public W(string s); public W(string s, byte[] data); // more constructors [MethodImpl(MethodImplOptions.InternalCall)] internal extern W(string s, int i); public static W Func(string s, int i); } I am trying to call "internal extern" constructor or Func using reflections MethodInfo dynMethod = typeof(W).GetMethod("Func", BindingFlags.Static); object[] argVals = new object[] { "hi", 1 }; dynMethod.Invoke(null, argVals); and Type type = typeof(W); Type[] argTypes = new Type[] { typeof(System.String), typeof(System.Int32) }; ConstructorInfo cInfo = type.GetConstructor(BindingFlags.InvokeMethod | BindingFlags.NonPublic, null, argTypes, null); object[] argVals = new object[] { "hi", 1 }; dynMethod.Invoke(null, argVals); unfortunantly both variants rise NullReferenceException when trying to Invoke, so, I must be doing something wrong?

• How are Scala traits compiled into Java bytecode?

  - by Justin Ardini

  I have played around with Scala for a while now, and I know that traits can act as the Scala equivalent of both interfaces and abstract classes. Recently I've been wondering how exactly traits are compiled into Java bytecode. I found some short explanations that stated traits are compiled exactly like Java interfaces when possible, and interfaces with an additional class otherwise. I still don't understand, however, how Scala achieves class linearization, a feature not available in Java. Could anyone explain or provide a good source explains how traits compile to Java bytecode?

• How to paint fully transparent pixels/points in P2D mode?

  - by netzwerg

  According to the Processing Reference, stroke(gray, alpha) allows to set the color and opacity of the stroke. With the default color mode, an alpha value of 255 denotes full opacity, while a value of 0 should correspond to complete transparency. While this works with the (default) JAVA2D renderer, I can't seem to paint fully transparent points in P2D mode. This code clearly renders a pixel at the center of the canvas, even though the alpha value is set to 0 (fully transparent): public class Transparency extends PApplet { @Override public void setup() { size(200, 200, P2D); } @Override public void draw() { stroke(0, 0); point(width / 2, height / 2); } public static void main(String[] args) { PApplet.main(new String[] { Transparency.class.getSimpleName() }); } } What's wrong here?

• Using Linq methods causes missing references to DependencyObject in WindowsBase

  - by Jason Coyne

  I have some c# source that I want to compile using CodeDom within my application (for a plugin) Everything works fine, except if I use a Linq extension function on some of my collections var dict = new Dictionary<KeyType, ValueType>(); .... dict.Any(KV=>KV.Key == "Some Key); When I try to compile source that has this code, it CodeDom complains that I am missing a reference to DependencyObject in WindowsBase. I do not understand why this is happening. Neither the Dictionary class, or the Any extension method reference that class, which apparently is part of Windows.Forms I would normally just ignore the quirk, make the CodeDom add a reference and move on, but Apparently WindowsBase is special and is not always distributed and I don't want to cause issues for users that may not have it installed correctly.

• Ninject - initialise objects

  Hi guys, I am new to ninject, I am wondering how I can run custom initizlisation code when constructing the injected objects? ie. I have a Sword class which implements IWeapon, but I want to pass an hit point value to the Sword class constructor, how do I achieve that? Do I need to write my own provider? A minor question, IKernel kernel = new StandardKernel(new Module1(), new Module2(), ...); what is the actual use of having multiple modules in Kernel? I sorta understand it, but could someone give me a formal explaination and use case? Thanks a lot! James

• How to change default image of derived ToolStripButton?

  - by Special Touch

  It seems like a simple task. Create a C# class that derives from ToolStripButton. The derived ToolStripButton should behave exactly the same as the parent class in the designer and the application, except that the default image should be different. Surprisingly just changing the constructor is not sufficient: public CustomToolStripButton() { base.Image = (Image) new Bitmap(typeof(CustomToolStripButton), "CustomImage.bmp"); } When the ToolStripButton is displayed in the designer, the original default image is shown. There must be a simple solution. What could it be?

• Why does Android Account & Sync reboot when trying to find my settings activity?

• How to configure maximum number of transport channels in WCF using basicHttpBinding?

  - by Hemant

  Consider following code which is essentially a WCF host: [ServiceContract (Namespace = "http://www.mightycalc.com")] interface ICalculator { [OperationContract] int Add (int aNum1, int aNum2); } [ServiceBehavior (InstanceContextMode = InstanceContextMode.PerCall)] class Calculator: ICalculator { public int Add (int aNum1, int aNum2) { Thread.Sleep (2000); //Simulate a lengthy operation return aNum1 + aNum2; } } class Program { static void Main (string[] args) { try { using (var serviceHost = new ServiceHost (typeof (Calculator))) { var httpBinding = new BasicHttpBinding (BasicHttpSecurityMode.None); serviceHost.AddServiceEndpoint (typeof (ICalculator), httpBinding, "http://172.16.9.191:2221/calc"); serviceHost.Open (); Console.WriteLine ("Service is running. ENJOY!!!"); Console.WriteLine ("Type 'stop' and hit enter to stop the service."); Console.ReadLine (); if (serviceHost.State == CommunicationState.Opened) serviceHost.Close (); } } catch (Exception e) { Console.WriteLine (e); Console.ReadLine (); } } } Also the WCF client program is: class Program { static int COUNT = 0; static Timer timer = null; static void Main (string[] args) { var threads = new Thread[10]; for (int i = 0; i < threads.Length; i++) { threads[i] = new Thread (Calculate); threads[i].Start (null); } timer = new Timer (o => Console.WriteLine ("Count: {0}", COUNT), null, 1000, 1000); Console.ReadLine (); timer.Dispose (); } static void Calculate (object state) { var c = new CalculatorClient ("BasicHttpBinding_ICalculator"); c.Open (); while (true) { try { var sum = c.Add (2, 3); Interlocked.Increment (ref COUNT); } catch (Exception ex) { Console.WriteLine ("Error on thread {0}: {1}", Thread.CurrentThread.Name, ex.GetType ()); break; } } c.Close (); } } Basically, I am creating 10 proxy clients and then repeatedly calling Add service method. Now if I run both applications and observe opened TCP connections using netstat, I find that: If both client and server are running on same machine, number of tcp connections are equal to number of proxy objects. It means all requests are being served in parallel. Which is good. If I run server on a separate machine, I observed that maximum 2 TCP connections are opened regardless of the number of proxy objects I create. Only 2 requests run in parallel. It hurts the processing speed badly. If I switch to net.tcp binding, everything works fine (a separate TCP connection for each proxy object even if they are running on different machines). I am very confused and unable to make the basicHttpBinding use more TCP connections. I know it is a long question, but please help!

• Exercise 26 of The Pragmatic Programmer

  - by _ande_turner_

  There is a code snippet presented in The Pragmatic Programmer on page 143 as: public class Colada { private Blender myBlender; private Vector myStuff; public Colada() { myBlender = new Blender(); myStuff = new Vector(); } private doSomething() { myBlender.addIngredients(myStuff.elements()); } } This obeys the Law of Demeter / Principle of Least Knowledge. Is it preferable to, and are there any caveats for, replacing it with the following, which utilises Dependency Injection? public class Colada throws IllegalArgumentException { private Blender myBlender; private Vector myStuff; public Colada(Blender blender, Vector stuff) { blender == null ? throw new IllegalArgumentException() : myBlender = blender; stuff == null ? throw new IllegalArgumentException() : myStuff = stuff; } public getInstance() { Blender blender = new Blender(); Vector stuff = new Vector(); return new Colada(blender, stuff); } private doSomething() { myBlender.addIngredients(myStuff.elements()); } }
