• Is there a SortedList<T> class in .net ? (not SortedList<Key,Value> which is actually a kind of Sort

  - by Brann

  I need to sort some objects according to their contents (in fact according to one of their properties, which is NOT the key and may be duplicated between different objects) .net provides two classes (SortedDictionnary and SortedList), and both are some kind of Dictionaries. The only difference (AFAIK) is that SortedDictionnary uses a binary tree to maintain its state whereas SortedList does not and is accessible via an index. I could achieve what I want using a List, and then using its Sort() method with a custom implementation of IComparer, but it wouldn't be time-efficient as I would sort the whole List each time I insert a new object, whereas a good SortedList would just insert the item at the right position. What I need is a SortedList class with a RefreshPosition(int index) to move only the changed (or inserted) object rather than resorting the whole list each time an object inside changes. Am I missing something obvious ?

• Using table-of-contents in code?

  - by AareP

  Do you use table-of-contents for listing all the functions (and maybe variables) of a class in the beginning of big source code file? I know that alternative to that kind of listing would be to split up big files into smaller classes/files, so that their class declaration would be self-explanatory enough.. but some complex tasks require a lot of code. I'm not sure is it really worth it spending your time subdividing implementation into multiple of files? Or is it ok to create an index-listing additionally to the class/interface declaration?

• Repository vs Data Access

  - by vdh_ant

  Hi guys In the context of the n-tier application, is there a difference between what you would consider your data access classes to be and your repositories? I tend to think yes but I just wanted to see what other thought. My thinking is that the job of the repository is just to contain and execute the raw query itself, where as the data access class would create the context, execute the repository (passing in the context), handle mapping the data model to the domain model and return the result back up... What do you guys think? Also do you see any of this changing in a Linq to XML scenario (assuming that you change the context for the relevant XDocument)? Cheers Anthony

• Invoke Maven-Module build from intellij

  - by Roman

  Hi All I was wondering if someone knows a way to invoke a specific maven module build from IntelliJ that will also build ( or use already compiled classes ) from depended modules. So for instance if I would like to build the module "Model" in the picture and only it , it seems reasonable for me to click the package step on it. But what is actually does it invokes the mvn package step inside this specific module rather than "mvn -am -pl module-name" from the root module , which also builds all the dependencies. So is there something that I just don't know ?

• Overcoming C limitations for large projects

  - by Francisco Garcia

  One aspect where C shows its age is the encapsulation of code. Many modern languages has classes, namespaces, packages... a much more convenient to organize code than just a simple "include". Since C is still the main language for many huge projects. How do you to overcome its limitations? I suppose that one main factor should be lots of discipline. I would like to know what you do to handle large quantity of C code, which authors or books you can recommend.

• Do controls need to be defined in a web app or will .NET do it for you

  - by Chris

  I always thought that when you dropped a control onto an .aspx page that a declaration of that control ended up being generated for you (either in a designer file, or within your code behind). All of the apps I have worked on have worked this way. A coworker of mine was installing resharper and it was showing that all her code behind pages would not build. Turned out that resharper could not find a definition for any control that she has dropped onto her markup. She has no designer files, and no declarations in markup. Do they get automatically built when putting together the partial classes? Is there an option at that page/project level to instruct .NET to do this for you? Is this a difference between web app and web site? This is a a .NET 3.5 site, C#, and it is running in a production environment. Thanks in advance

• How do I structure a GWT project?

  - by smaye81

  Hello, I have followed the basic GWT tutorial for creating a project in Eclipse. Now, I am trying to build off what I learned in the tutorial. I created a static utility class to perform some database connection logic. However, when I try to compile I get: [ERROR] Line 46: No source code is available for type com.sample.server.ConnectionUtil; did you forget to inherit a required module? Where can I put simple classes that I've created on my own? Do they have to be outside the package structure of the basic module, 'com.sample'? Or do I have to specify a whole new module in the gwt.xml file and inherit from that? There has to be something simple I'm missing.

• Better to use constructor or method factory pattern?

  - by devoured elysium

  I have a wrapper class for the Bitmap .NET class called BitmapZone. Assuming we have a WIDTH x HEIGHT bitmap picture, this wrapper class should serve the purpose of allowing me to send to other methods/classes itself instead of the original bitmap. I can then better control what the user is or not allowed to do with the picture (and I don't have to copy the bitmap lots of times to send for each method/class). My question is: knowing that all BitmapZone's are created from a Bitmap, what do you find preferrable? Constructor syntax: something like BitmapZone bitmapZone = new BitmapZone(originalBitmap, x, y, width, height); Factory Method Pattern: BitmapZone bitmapZone = BitmapZone.From(originalBitmap, x , y, width, height); Factory Method Pattern: BitmapZone bitmapZone = BitmapZone.FromBitmap(originalBitmap, x, y, width, height); Other? Why? Thanks

• building a web application in eclipse

  - by Noona

  As a concluding assignment for the technologies taught in a data management course, we have to write a web application using the technologies taught throughout the course, this mostly includes xhtml, css, JSP, servelets, JDBC, AJAX, webservices. the project will eventually be deployed using tomcat. we are given the option of choosing the technologies that we see fit. since this is my first time developing a web application I am having some uncertainties about where to start, so for example now I am writing the object classes that will be used in the database and implementing the operations that will be performed on the database, but I am not sure about how to make these operations available to a client through the website, I mean I think I have to write a servlet through which I can extract the request parameters and set the response accordingly, but I would still like a more specific overview of what I am going to do, so if someone can link me to a tutorial with an example that makes use of these technologies while illustrating the stages of the design so that I can see how all these things are linked together in a web project. thanks

• Code understanding, reverse engineering, best concepts and tools. Java.

  - by core07

  One of most demanding tasks for any programmer, architect is understanding other's code. E.g. I am contractor, hired to rescue some project very quickly. Fix bugs, plan global refactoring and therefore I need most efficient way to understand the code. What is the list of concepts, their priority and best tools for this? Of what I know: reverse code engineering to create object models (creating of diagram per package is not so convenient), create sequence diagrams (the tool connects in debug mode to the system and generates diagrams from runtime). Some visualizing techniques, using some tools to work not just with .java but also with e.g. JPA implementors like Hibernate. Generate diagram for not all the codebase, but add some class and then classes used by it. Is Sparx Enterprise Architect state of the art in reverse engineering or far from that. Any other better tools? Ideally would be that tool makes me understand the code as if I wrote it myself :)

• getResourceAsStream not loading resource in webapp

  - by mangst

  I have a web application that uses a library which resides in TOMCAT_HOME/common/lib. This library looks for a properties file at the root of the classpath (in a class called ApplicationConfig): ApplicationConfig.class.getResourceAsStream("/hv-application.properties"); My Tomcat web application contains this properties file. It is in WEB-INF/classes, which is the root of the classpath right? However, at runtime, when it tries to load the properties file, it throws an exception because it can't find it (getResourceAsStream returns null). Everything works fine if my application is a simple, standalone Java application. Does Tomcat cause the getResourceAsStream method to act differently? I know there's a lot of similar questions out there, but none of them have helped unfortunately. Thanks.

• Immutable Dot Net strings

  - by klork

  I usually define my string variables in vb.net as Dim f_sName as string=String.Empty f_sName = "foo" Given the immutable nature of strings in .net, is there a better way to initialize strings and deal with the "Variable 'f_sName ' is used before it has been assigned a value. A null reference exception could result at runtime." warning? Also for classes that do not have constructors which accept no arguments such as System.Net.Sockets.NetworkStream, what is the best way to define and initialize a variable of that type? All comments are highly appreciated. Thanks

• What's the smartest way to organize SVN for translated versions of the same project?

  - by brandonjp

  I apologize because I know this has been covered over and over again, but I'm trying to understand the smartest way to cleverly use subversion to our benefit. (*Note: I know our method is not the BEST way to handle localized versions, but external factors are forcing us to work this way on current projects) We have a fairly static website in English...html, css, js, etc. After the site comes back from the translator we will have 5 variations of the same code (this week...then potentially 25 more in the future!). So we'll soon have a folder for EN, FR, SP, DE, etc. Most files (css, js, img) will remain exactly the same; and html files (structure, id's, classes) will only vary based on the localized text inside the elements. Is there any way to use clever SVN folder structuring that would help us out in the event that if a small change is needed, we don't have to manually change the files in each and every translated version of the site? Thanks! --bp

• Asset tracking in "real-time" - how best to display in browser?

  - by mawg

  I am developing an asset tracking system, standard LAMP, and now am wondering how best to present the data to the user in the browser. I expect to track and most a few thousand items, and to refresh them every second or so. I want to draw a floorplan or map of the area and represent the assets the assets symbolically on that (with different symbols for different classes of assets). Additionally, the user should be able to click on an asset to interact with it, and search for a particular asset and centre the screen on it, draw a circle round it, etc http://graphite.wikidot.com/ Looks good - is there any alternative? At its simplest, I suppose I could just generate a JPEG and display it, using CSS to let me know if/where a user clicks ... but what's the "best" way to do it?

• Maximizing the number of threads to fully utilize all available resources without hindering overall

  - by Matt

  Let's say I have to generate a bunch of result files, and I want to make it as fast as possible. Each result file is generated independently of any other result file; in fact, one could say that each result file is agnostic to every other result file. The resources used to generate each result file is also unique to each. How can I dynamically decide the optimal number of threads to run simultaneously in order to minimize the overall run time? Is my only option to write my own thread manager that watches performance counters and adjust accordingly or does there exists some solid classes that already accomplish this?

• Fastest method for SQL Server inserts, updates, selects

  - by Ian

  I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

• How do I combine an unmanaged dll and a managed assembly into one file?

  - by Lasse V. Karlsen

  SQLite from PHX Software has combined a managed assembly (System.Data.SQLite) with an unmanaged dll (the SQLite 32- or 64-bit dll) into one file, and managed to link them together. How do I do this? Do I need to embed the managed assembly into the unmanaged dll, or vice versa? ie. my questions are: In which order do I need to do this? What tools or knowledge do I need in order to do this? How (if different) do I link to the exported functions from the unmanaged dll in my managed code? The reason I ask this is that I want to build a managed zLib wrapper. I know there is managed classes in .NET but from experience they're a bit limited (and a bit boneheaded in that they don't do proper buffering), so I'd like to create my own copy, also because I want to learn how to do this. So does anyone know what I need to do and how?

• Interface and base class mix, the right way to implement this

  - by Lerxst

  I have some user controls which I want to specify properties and methods for. They inherit from a base class, because they all have properties such as "Foo" and "Bar", and the reason I used a base class is so that I dont have to manually implement all of these properties in each derived class. However, I want to have a method that is only in the derived classes, not in the base class, as the base class doesn't know how to "do" the method, so I am thinking of using an interface for this. If i put it in the base class, I have to define some body to return a value (which would be invalid), and always make sure that the overriding method is not calling the base. method Is the right way to go about this to use both the base class and an interface to expose the method? It seems very round-about, but every way i think about doing it seems wrong... Let me know if the question is not clear, it's probably a dumb question but I want to do this right.

• Should i use HttpResponse.End() for a fast webapp?

  - by acidzombie24

  HttpResponse.End() seems to throw an exception according to msdn. Right now i have the choice of returning a value to say end thread (it only goes 2 functions deep) or i can call end(). I know that throwing exceptions is significantly slower (read the comment for a C#/.NET test) so if i want a fast webapp should i consider not calling it when it is trivially easy to not call it? -edit- I do have a function call in certain functions and in the constructor in classes to ensure the user is logged in. So i call HttpResponse.End() in enough places although hopefully in regular site usage it doesn't occur too often.

• call flex initComplete at a specific time

  - by dubbeat

  Hi, Below is the overriden on complete function for a preloader in Flex. private function initComplete(e:Event):void { //dispatchEvent(new Event(Event.COMPLETE)); cp.status.text="Configuring... Please Wait"; } What I want to do is when the app has finsihed loading I want to change the preloaders text to "configuring". Then I want to go and do a bunch of setup stuff in my code. Once I've done all the setup I wanted how can I get the Preloader to dispatch its Event.complete from else where in my code? I tried Application.application.preloader but it comes up null. So I guess my question really is how to access a preloader from anywhere in my application. Would a better approach be to have all setup classes as members of my preloader class?

• polymorphism pass instantiated base to deriver

  - by Eric

  I was wondering how to do this, consider the following classes public class Fruit { public string Name { get; set; } public Color Color { get; set; } } public class Apple : Fruit { public Apple() { } } How can I instantiate a new fruit but upcast to Apple, is there a way to instantiate a bunch of Fruit and make them apples with the name & color set. Do I need to manually deep copy? Of course this fails Fruit a = new Fruit(); a.Name = "FirstApple"; a.Color = Color.Red; Apple wa = a as Apple; System.Diagnostics.Debug.Print("Apple name: " + wa.Name); Do I need to pass in a Fruit to the AppleCTor and manually set the name and color( or 1-n properties) Is there an better design to do this?

• How to add ServiceReference to an embedded file?

  - by TruMan1

  I have a class library. In one of the classes, I am adding a script reference on the page like this: protected override void OnPreRender(EventArgs e) { base.OnPreRender(e); if (this.Page != null) { ScriptManager sm = ScriptManager.GetCurrent(this.Page); ServiceReference reference = new ServiceReference("~/Sitefinity/Admin/Services/ContactsService.asmx"); reference.InlineScript = true; sm.Services.Add(reference); } } For the ServiceReference file path, is there a way to add an embedded file instead? I want to keep everything self-contained in my class library instead of dropping a file into the website folder.

  Hi Java programmers. I badly need your help. I have a JavaFX/Java ME application. I'm trying to modify an XML file inside my project's folder (soon to be packaged jar file). The path of the file I want to write: /parseExample/service1.xml Sadly, my application is a JavaFx/JavaME so it doesn't contain the library java.util.jar. So I can't use the jar classes. Are there other ways to do that?

• get static initialization block to run in a java without loading the class

  - by TP

  I have a few classes as shown here public class TrueFalseQuestion implements Question{ static{ QuestionFactory.registerType("TrueFalse", "Question"); } public TrueFalseQuestion(){} } ... public class QuestionFactory { static final HashMap<String, String > map = new HashMap<String,String>(); public static void registerType(String questionName, String ques ) { map.put(questionName, ques); } } public class FactoryTester { public static void main(String[] args) { System.out.println(QuestionFactory.map.size()); // This prints 0. I want it to print 1 } } How can I change TrueFalseQuestion Type so that the static method is always run so that I get 1 instead of 0 when I run my main method? I do not want any change in the main method. I am actually trying to implement the factory patterns where the subclasses register with the factory but i have simplified the code for this question.
