  • Is it dangerous for me to give some of my Model classes Control-like methods?

    - by Pureferret
    In my personal project I have tried to stick to MVC, but I've also been made aware that sticking to MVC too tightly can be a bad thing as it makes writing awkward and forces the flow of the program in odd ways (i.e. some simple functions can be performed by something that normally wouldn't, and avoid MVC related overheads). So I'm beginning to feel justified in this compromise: I have some 'manager programs' that 'own' data and have some way to manipulate it, as such I think they'd count as both part of the model, and part of the control, and to me this feels more natural than keepingthem separate. For instance: One of my Managers is the PlayerCharacterManager that has these methods: void buySkill(PlayerCharacter playerCharacter, Skill skill); void changeName(); void changeRole(); void restatCharacter(); void addCharacterToGame(); void createNewCharacter(); PlayerCharacter getPlayerCharacter(); List<PlayerCharacter> getPlayersCharacter(Player player); List<PlayerCharacter> getAllCharacters(); I hope the mothod names are transparent enough that they don't all need explaining. I've called it a manager because it will help manage all of the PlayerCharacter 'model' objects the code creates, and create and keep a map of these. I may also get it to store other information in the future. I plan to have another two similar classes for this sort of control, but I will orchestrate when and how this happens, and what to do with the returned data via a pure controller class. This splitting up control between informed managers and the controller, as opposed to operating just through a controller seems like it will simplify my code and make it flow more. My question is, is this a dangerous choice, in terms of making the code harder to follow/test/fix? Is this somethign established as good or bad or neutral? I oculdn't find anything similar except the idea of Actors but that's not quite why I'm trying to do. Edit: Perhaps an example is needed; I'm using the Controller to update the view and access the data, so when I click the 'Add new character to a player button' it'll call methods in the controller that then go and tell the PlayerCharacterManager class to create a new character instance, it'll call the PlayerManager class to add that new character to the player-character map, and then it'll add this information to the database, and tell the view to update any GUIs effected. That is the sort of 'control sequence' I'm hoping to create with these manager classes.

  • Checking For Empty Enumerations

    While spelunking in some code recently I saw a method that looked something like this: public void Foo<T>(IEnumerable<T> items) { if(items == null || items.Count() == 0) { // Warn about emptiness } } This method accepts a generic enumeration and then proceeds to check if the enumeration is null or empty. Do you see the potential problem with this code? Ill give you a hint, its this line: items.Count() == 0 Whats the problem? Well that line right there has the potential...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • How to redesign the UI of a large project?

    - by jem88
    I'm currently working at a quite big Android project (a social network, you can see it here if is useful to answer the question). We decided to restyle the whole app, changing all the UI design. The code I actually have is complex, there are many controllers, and it's a little messy too. Is it "better" in terms of time and code cleanliness to take one controller per time, and rewrite it entirely, or to modify one controller per time? The layout change entirely anyway, so for that I know I've to restart from scratch. Maybe it could seem a stupid question, but with the "time" variable I really can't see the best way.

  • FxCop ... Where have you been all my life?

    - by PhilSando
    I was recently introduced to microsoft's tool that analyzes managed code assemblies called FxCop. It points out possible design, localization, performance, and security improvements against a pre defined set of rules (and also accepts custom rules). At first I was unsure how to go about using it as it seems to be aimed at software developers (.exe and .dll) . Its easy to get around this with the following steps: 1)Create a new folder (i.e C:\Code Analysis) 2)Publish your web application into the new folder 3)Open FxCop and add all the dll files from the newly created bin folder  to be scrutinized. Lots more info / docs available here on msdn and you can also download fxcop free

  • What's the most productive coding environment

    - by Ubiguchi
    I was speaking with an ex-colleague the other day about the most productive way to write code and he said he found it best "to CIMP, or Code In My Pants". When I asked him exactly what he meant, he explained he found it best to work at home, coding at his own pace, dressed comfortably (in his pants), and communicating with his team through emails, IM, or the telephone. Digesting his approach (which he describes to clients as the Complete Integrated Method of Programming), I realised my coding is also more productive when working in an isolated environment, which made me wonder if the software industry has got it all wrong and should development be really done by dispersed teams of individuals, or are there advantages to geographical herding that make up for the added interruptions it brings? So has business got it wrong? Should development occur predominantly across geographically isolated individuals to increase productivity, or are there real reasons why herding developers together makes sense?

  • IXRepository and test problems

    - by Ridermansb
    Recently had a doubt about how and where to test repository methods. Let the following situation: I have an interface IRepository like this: public interface IRepository<T> where T: class, IEntity { IQueryable<T> Query(Expression<Func<T, bool>> expression); // ... Omitted } And a generic implementation of IRepository public class Repository<T> : IRepository<T> where T : class, IEntity { public IQueryable<T> Query(Expression<Func<T, bool>> expression) { return All().Where(expression).AsQueryable(); } } This is an implementation base that can be used by any repository. It contains the basic implementation of my ORM. Some repositories have specific filters, in which case we will IEmployeeRepository with a specific filter: public interface IEmployeeRepository : IRepository<Employee> { IQueryable<Employee> GetInactiveEmployees(); } And the implementation of IEmployeeRepository: public class EmployeeRepository : Repository<Employee>, IEmployeeRepository // TODO: I have a dependency with ORM at this point in Repository<Employee>. How to solve? How to test the GetInactiveEmployees method { public IQueryable<Employee> GetInactiveEmployees() { return Query(p => p.Status != StatusEmployeeEnum.Active || p.StartDate < DateTime.Now); } } Questions Is right to inherit Repository<Employee>? The goal is to reuse code once all implementing IRepository already been made. If EmployeeRepository inherit only IEmployeeRepository, I have to literally copy and paste the code of Repository<T>. In our example, in EmployeeRepository : Repository<Employee> our Repository lies in our ORM layer. We have a dependency here with our ORM impossible to perform some unit test. How to create a unit test to ensure that the filter GetInactiveEmployees return all Employees in which the Status != Active and StartDate < DateTime.Now. I can not create a Fake/Mock of IEmployeeRepository because I would be testing? Need to test the actual implementation of GetInactiveEmployees. The complete code can be found on Github

  • How do I calculate the motion of 2 massive bodies in space?

    - by 1224
    I'm writing code simulating the 2-dimensional motion of two massive bodies with gravitational fields. The bodies' masses are known and I have a gravitational force equation. I know from that force I can get a differential equation for coordinates. I know that I once I solve this equation I will get the coordinates. I will need to make up some initial position and some initial velocity. I'd like to end up with a numeric solver for the ordinal differential equation for coordinates to get the formulas that I can write in code. Could someone break down how from laws and initial conditions we get to the formulas that calculate x and y at time t?

  • New Window Via JavaScript Clears Parent

    - by Bunch
    This is not a new item at all but I came across it recently. For an app I had been using some JavaScript like: javascript:window.open(someurl.aspx here) to open a new window via a button. That bit of code had been working great in several other apps. Then in one app that same code decided to open the new window correctly while clearing the parent of everything but [object]. The fix ended up being simple, change the javascript to: javascript:void(window.open(someurl.aspx here); Then it worked like I thought it should. Tags: ASP.Net, JavaScript

  • Writing scripts for Visual Studio project

    - by oillio
    What is the best way to write and run small scripts and tasks that are specific to a particular .Net project? Such things as configuring a database or confirming proper connections to servers. In Ruby, I would build rake tasks for this sort of thing. I am currently using unit tests for these tasks as they are easy to run within VS and they have access to all the necessary libraries and project code. However, this is not really their intended purpose and, with the dropping of Test Lists in VS 2012, it does not work nearly as well as it used to. Is there a better solution than writing a console project to handle these little code snippets I need to run periodically?

  • How do you usually manage callbacks in Java using Swing library?

    - by none
    I'm quite new to the Java Swing programming, and GUI development as well. As a beginner, I'm currently reading Design Pattern, but finding what I'm looking for is quite hard, most of the times. So far, I've never had huge problems defining a view hierarchy - I just use to subclass component from component. But the hard-to-do here is how managing callbacks, which often become hard to maintain due to the hard code. During my last projects, I tried to separate GUI, Listener and Callbacker objects which cooperated together, but in this way it was really hard adding new features. So, which kind of best patterns or best practices do you tend to use when trying to maintain, add new features or even worst avoid to hard-code classes which manage callbacks method in this kind of frameworks (mainly Java Swing)?

  • Flattening System.Web.UI ControlCollection

    - by evovision
    Hi,   Sometimes one may need to get a list of child controls inside specific container and don't care about the underlying hierarchy.   The result is beautifully achieved using this extension method:   using System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.UI;    public static class ControlCollectionExtensionMethods    {        public static IEnumerable<Control> FlattenedList(this ControlCollection controls)        {            foreach (Control ctrl in controls)            {                  // return parent control                   yield return ctrl;                              // and dive into child collection                   foreach (Control child in ctrl.Controls.FlattenedList())                         yield return child;            }        }    }   P.S.: don't forget about namespaces when using it in your code, if above class is wrapped into namespace, for example: Sample, the source code file with calling code must explicitly reference it: using Sample;

  • What's involved in resetting the graphics device?

    - by Donutz
    I'm playing with XNA 4.0, VS2010. I've created a window (not maximized) and drawn some sprites. All is good until I resize the window, after which the sprites stop displaying or only partially display. I'm pretty sure it has something to do with needing to reset the device or something, but can't find any clear instructions or sample code. It's not just a case of needing to increase the preferredbackbuffer size, because even if I shrink the window I get this symptom. I've looked at the source code that I was able to get from Microsoft before they shut down XNA, but it doesn't actually explain anything. Any help or advice? If it makes any difference I'm creating DrawableGameComponents and doing my updates and drawing in their Draw/Update routines.

  • Accessing Master Page Controls

    - by Bunch
    Sometimes when using Master Pages you need to set a property on a control from the content page. An example might be changing a label’s text to reflect some content (e.g. customer name) being viewed or maybe to change the visibility of a control depending on the rights a user may have in the application. There are different ways to do this but this is the one I like. First on the code behind of the Master Page create the property that needs to be accessed. An example would be: Public Property CustomerNameText() As String     Get         Return lblCustomerName.Text     End Get     Set(ByVal value As String)         lblCustomerName.Text = value     End Set End Property Next in the aspx file of the content page add the MasterType directive like: <%@ MasterType VirtualPath="~/MasterPages/Sales.master" %> Then you can access the property in any of the functions of the code behind of the aspx content page. Master.CustomerNameText = “ABC Store” Technorati Tags: ASP.Net,VB.Net

  • Fixing a bug that has never caused a problem until now.

    - by codeelegance
    I recently made a change that caused some code to be run far more often than it used to. This lead to the discovery of a bug. This bug had the potential to happen any time that code was run but because it was run so seldom it never surfaced. When I brought this to the lead developer's attention he wanted me to undo the change that exposed the bug rather than fix the bug quoting the adage, "If it ain't broke, don't fix it". Its clear to me that we were just lucky up until now but he won't listen to reason. Should I fix it anyway? Update The lead technically doesn't have any authority over me. Just tenure. He's been the sole developer on the project for a number of years until a year ago and I think he doesn't take constructive criticism very well. For what's worth, I didn't criticize him I just pointed out that just because the bug never showed up didn't mean it wasn't there.

  • Making CopySourceAsHtml add-on work with VS2010

    - by DigiMortal
    As there are still bloggers who use CopySourceAsHtml add-on for Visual Studio to get syntax highlighted code to their blog posts and there is no guidance in CSAH site how to make it work with Visual Studio 2010 I will give my guidance here. Almost all code in this blog is syntax highlighted by this add-on (read more from my post Visual Studio add-in: CopySourceAsHTML). Last version of CSAH is available for VS2008 but it is easy to make it work with VS2010. Just follow these steps. Close VS2010 if it is opened. Goto folder MyDocuments\Visual Studio 2010. Move to AddIns subfolder (create it if there is no such subfolder). Create file called CopySourceAsHtml.AddIn and open it in text editor. Paste the following XML to editor:   <?xml version="1.0" encoding="utf-8" standalone="no"?> <Extensibility xmlns="http://schemas.microsoft.com/AutomationExtensibility"> <HostApplication> <Name>Microsoft Visual Studio Macros</Name> <Version>10.0</Version> </HostApplication> <HostApplication> <Name>Microsoft Visual Studio</Name> <Version>10.0</Version> </HostApplication> <Addin> <FriendlyName>CopySourceAsHtml</FriendlyName> <Description>Adds support to Microsoft Visual Studio 2010 for copying source code, syntax highlighting, and line numbers as HTML.</Description> <Assembly>JTLeigh.Tools.Development.CopySourceAsHtml, Version=3.0.3215.1, Culture=neutral, PublicKeyToken=bb2a58bdc03d2e14, processorArchitecture=MSIL</Assembly> <FullClassName>JTLeigh.Tools.Development.CopySourceAsHtml.Connect</FullClassName> <LoadBehavior>1</LoadBehavior> <CommandPreload>0</CommandPreload> <CommandLineSafe>0</CommandLineSafe> </Addin> </Extensibility> Save file and close it. Run VS2010 and activate add-on if it is not activated yet. That’s it. If you are heavy user of CSAH then I recommend you to bookmark this post. :)
