  • c# class design - what can I use instead of "static abstract"?

    - by Ryan
    I want to do the following public abstract class MyAbstractClass { public static abstract int MagicId { get; } public static void DoSomeMagic() { // Need to get the MagicId value defined in the concrete implementation } } public class MyConcreteClass : MyAbstractClass { public static override int MagicId { get { return 123; } } } However I can't because you can't have static abstract members. I understand why I can't do this - any recommendations for a design that will achieve much the same result? (For clarity - what I am trying to do is provide a library with an abstract base class but the concrete versions MUST implement a few properties/methods themselves and yes, there are good reasons for keeping it static.)

  • How can Domain driven design be combined with aspect oriented programming?

    - by anthares
    I'm doing research and one point I want to cover is "What is the relationship between Domain-driven Design and Aspect oriented programming?" I know that a main principle in DDD is separation of concerns and I understand that. What I'm not really certain is, whether aspects in AOP acts like "sub domains" in our domain in DDD. Are these two concepts, basically the same thing. I mean, If I develop an application following AOP and DDD, at the end of the day will it be true that "a sub domain" == "an aspect". I will also appreciate any other opinions what is the common between AOP and DDD.

  • Does my use of the strategy pattern violate the fundamental MVC pattern in iOS?

    - by Goodsquirrel
    I'm about to use the 'strategy' pattern in my iOS app, but feel like my approach violates the somehow fundamental MVC pattern. My app is displaying visual "stories", and a Story consists (i.e. has @properties) of one Photo and one or more VisualEvent objects to represent e.g. animated circles or moving arrows on the photo. Each VisualEvent object therefore has a eventType @property, that might be e.g. kEventTypeCircle or kEventTypeArrow. All events have things in common, like a startTime @property, but differ in the way they are being drawn on the StoryPlayerView. Currently I'm trying to follow the MVC pattern and have a StoryPlayer object (my controller) that knows about both the model objects (like Story and all kinds of visual events) and the view object StoryPlayerView. To chose the right drawing code for each of the different visual event types, my StoryPlayer is using a switch statement. @implementation StoryPlayer // (...) - (void)showVisualEvent:(VisualEvent *)event onStoryPlayerView:storyPlayerView { switch (event.eventType) { case kEventTypeCircle: [self showCircleEvent:event onStoryPlayerView:storyPlayerView]; break; case kEventTypeArrow: [self showArrowDrawingEvent:event onStoryPlayerView:storyPlayerView]; break; // (...) } But switch statements for type checking are bad design, aren't they? According to Uncle Bob they lead to tight coupling and can and should almost always be replaced by polymorphism. Having read about the "Strategy"-Pattern in Head First Design Patterns, I felt this was a great way to get rid of my switch statement. So I changed the design like this: All specialized visual event types are now subclasses of an abstract VisualEvent class that has a showOnStoryPlayerView: method. @interface VisualEvent : NSObject - (void)showOnStoryPlayerView:(StoryPlayerView *)storyPlayerView; // abstract Each and every concrete subclass implements a concrete specialized version of this drawing behavior method. @implementation CircleVisualEvent - (void)showOnStoryPlayerView:(StoryPlayerView *)storyPlayerView { [storyPlayerView drawCircleAtPoint:self.position color:self.color lineWidth:self.lineWidth radius:self.radius]; } The StoryPlayer now simply calls the same method on all types of events. @implementation StoryPlayer - (void)showVisualEvent:(VisualEvent *)event onStoryPlayerView:storyPlayerView { [event showOnStoryPlayerView:storyPlayerView]; } The result seems to be great: I got rid of the switch statement, and if I ever have to add new types of VisualEvents in the future, I simply create new subclasses of VisualEvent. And I won't have to change anything in StoryPlayer. But of cause this approach violates the MVC pattern since now my model has to know about and depend on my view! Now my controller talks to my model and my model talks to the view calling methods on StoryPlayerView like drawCircleAtPoint:color:lineWidth:radius:. But this kind of calls should be controller code not model code, right?? Seems to me like I made things worse. I'm confused! Am I completely missing the point of the strategy pattern? Is there a better way to get rid of the switch statement without breaking model-view separation?

  • Question on the implementation of my Entity System

    - by miguel.martin
    I am currently creating an Entity System, in C++, it is almost completed (I have all the code there, I just have to add a few things and test it). The only thing is, I can't figure out how to implement some features. This Entity System is based off a bit from the Artemis framework, however it is different. I'm not sure if I'll be able to type this out the way my head processing it. I'm going to basically ask whether I should do something over something else. Okay, now I'll give a little detail on my Entity System itself. Here are the basic classes that my Entity System uses to actually work: Entity - An Id (and some methods to add/remove/get/etc Components) Component - An empty abstract class ComponentManager - Manages ALL components for ALL entities within a Scene EntitySystem - Processes entities with specific components Aspect - The class that is used to help determine what Components an Entity must contain so a specific EntitySystem can process it EntitySystemManager - Manages all EntitySystems within a Scene EntityManager - Manages entities (i.e. holds all Entities, used to determine whether an Entity has been changed, enables/disables them, etc.) EntityFactory - Creates (and destroys) entities and assigns an ID to them Scene - Contains an EntityManager, EntityFactory, EntitySystemManager and ComponentManager. Has functions to update and initialise the scene. Now in order for an EntitySystem to efficiently know when to check if an Entity is valid for processing (so I can add it to a specific EntitySystem), it must recieve a message from the EntityManager (after a call of activate(Entity& e)). Similarly the EntityManager must know when an Entity is destroyed from the EntityFactory in the Scene, and also the ComponentManager must know when an Entity is created AND destroyed. I do have a Listener/Observer pattern implemented at the moment, but with this pattern I may remove a Listener (which is this case is dependent on the method being called). I mainly have this implemented for specific things related to a game, i.e. Teams, Tagging of entities, etc. So... I was thinking maybe I should call a private method (using friend classes) to send out when an Entity has been activated, deleted, etc. i.e. taken from my EntityFactory void EntityFactory::killEntity(Entity& e) { // if the entity doesn't exsist in the entity manager within the scene if(!getScene()->getEntityManager().doesExsist(e)) { return; // go back to the caller! (should throw an exception or something..) } // tell the ComponentManager and the EntityManager that we killed an Entity getScene()->getComponentManager().doOnEntityWillDie(e); getScene()->getEntityManager().doOnEntityWillDie(e); // notify the listners for(Mouth::iterator i = getMouth().begin(); i != getMouth().end(); ++i) { (*i)->onEntityWillDie(*this, e); } _idPool.addId(e.getId()); // add the ID to the pool delete &e; // delete the entity } As you can see on the lines where I am telling the ComponentManager and the EntityManager that an Entity will die, I am calling a method to make sure it handles it appropriately. Now I realise I could do this without calling it explicitly, with the help of that for loop notifying all listener objects connected to the EntityFactory's Mouth (an object used to tell listeners that there's an event), however is this a good idea (good design, or what)? I've gone over the PROS and CONS, I just can't decide what I want to do. Calling Explicitly: PROS Faster? Since these functions are explicitly called, they can't be "removed" CONS Not flexible Bad design? (friend functions) Calling through Listener objects (i.e. ComponentManager/EntityManager inherits from a EntityFactoryListener) PROS More Flexible? Better Design? CONS Slower? (virtual functions) Listeners can be removed, i.e. may be removed and not get called again during the program, which could cause in a crash. P.S. If you wish to view my current source code, I am hosting it on BitBucket.

  • In hindsight, is basing XAML on XML a mistake or a good approach?

    - by romkyns
    XAML is essentially a subset of XML. One of the main benefits of basing XAML on XML is said to be that it can be parsed with existing tools. And it can, to a large degree, although the (syntactically non-trivial) attribute values will stay in text form and require further parsing. There are two major alternatives to describing a GUI in an XML-derived language. One is to do what WinForms did, and describe it in real code. There are numerous problems with this, though it’s not completely advantage-free (a question to compare XAML to this approach). The other major alternative is to design a completely new syntax specifically tailored for the task at hand. This is generally known as a domain-specific language. So, in hindsight, and as a lesson for the future generations, was it a good idea to base XAML on XML, or would it have been better as a custom-designed domain-specific language? If we were designing an even better UI framework, should we pick XML or a custom DSL? Since it’s much easier to think positively about the status quo, especially one that is quite liked by the community, I’ll give some example reasons for why building on top of XML might be considered a mistake. Basing a language off XML has one thing going for it: it’s much easier to parse (the core parser is already available), requires much, much less design work, and alternative parsers are also much easier to write for 3rd party developers. But the resulting language can be unsatisfying in various ways. It is rather verbose. If you change the type of something, you need to change it in the closing tag. It has very poor support for comments; it’s impossible to comment out an attribute. There are limitations placed on the content of attributes by XML. The markup extensions have to be built "on top" of the XML syntax, not integrated deeply and nicely into it. And, my personal favourite, if you set something via an attribute, you use completely different syntax than if you set the exact same thing as a content property. It’s also said that since everyone knows XML, XAML requires less learning. Strictly speaking this is true, but learning the syntax is a tiny fraction of the time spent learning a new UI framework; it’s the framework’s concepts that make the curve steep. Besides, the idiosyncracies of an XML-based language might actually add to the "needs learning" basket. Are these disadvantages outweighted by the ease of parsing? Should the next cool framework continue the tradition, or invest the time to design an awesome DSL that can’t be parsed by existing tools and whose syntax needs to be learned by everyone? P.S. Not everyone confuses XAML and WPF, but some do. XAML is the XML-like thing. WPF is the framework with support for bindings, theming, hardware acceleration and a whole lot of other cool stuff.

  • Android chess development design [on hold]

    - by Plejo
    I want to develop human vs human android chess game and I have bunch of new questions. I would like to have screen where online players are shown(nickname, rating) and when player challenge antoher player and he accpet it game begins. These are my questions: When player install application, does he have to create account/login or does every instance of installed application have some kind of ID so I can recognize it on server side? I want to have also ratings of players saved in my DB so login procedure will probably be necessary. When player connects to server server updates online players list. When he challenge another player and he accept server exchange ip`s(and ports? which port to use?) between players. Then they connect to each other and game begins. What is best practice for connection between server-android and android-android? Probably sockets, right? Is there any library for handling lost connection etc.? Which server do you recommend?

  • Visual Studio 2010 SP1 Beta supports IIS Express

    - by DigiMortal
    Visual Studio 2010 SP1 Beta and ASP.NET MVC 3 RC2 were both announced today. I made a little test on one of my web applications to see how Visual Studio 2010 works with IIS Express. In this posting I will show you how to make your ASP.NET MVC 3 application work with IIS Express. Installing new stuff You can install IIS Express using Web Platform Installer. It is not part of WebMatrix anymore and you can just install IIS Express without WebMatrix. NB! You have to install IIS Express using Web Platform installer because IIS Express is not installed by SP1. After installing Visual Studio 2010 SP1 Beta on my machine (it took a long-long-long time to install) I installed also ASP.NET MVC 3 RC2. If you have Async CTP installed on your machine you have to uninstall it to get ASP.NET MVC 3 RC2 installed and run without problems. Screenshot on right shows what kinf of horrors my old laptop had to survive to get all new stuff installer. Setting IIS Express as server for web application Now, when you right-click on some web project you should see new menu item in context menu – Use IIS Express…. If you click on it you are asked for confirmation and if you say Yes then your web application is reconfigured to use IIS Express. After configuration you will see dialog box like this. And you are done. You can run your application now. Running web application When you run your application it is run on IIS Express. You can see IIS Express icon on taskbar and when you click it you can open IIS Express settings. If you closed your application in browser you can open it again from IIS Express icon. Modifying IIS Express settings for web application You can modify IIS Express settings for your application. Just open your project properties and move to Web tab. IIS and IIS Express are using same settings. The difference is if you make check to Use IIS Express checkbox or not. Switching back to Visual Studio Development Server If you don’t want or you can’t use IIS Express for some reason you can easily switch back to Visual Studio Development Server. Just right-click on your web application project and select Use Visual Studio Development Server from context menu. Conclusion IIS Express is more independent than full version of IIS and it can be also installed and run on machines where are very strict rules (some corporate and academic environments by example). IIS Express was previously part of WebMatrix package but now it is separate product and Visual Studio 2010 has very nice support for it thanks to SP1. You can easily make your web applications use IIS Express and if you want to switch back to development server it is also very easy.

  • ASP.NET 4 Hosting :: ValidateRequest=”false” not working in .Net 4.0 (VS.Net 2010)

    - by mbridge
    When we migrated our project from .NET 3.5 to .NET 4.0, we can get this error: Error: System.Web.HttpRequestValidationException A potentially dangerous Request.Form value was detected from the client (ctl00$CC$txtAnswer=\”… World\r\n\r\nI am doing Testin…\”).”} System.Web.HttpRequestValidationException at System.Web.HttpRequest.ValidateString(String value, String collectionKey, RequestValidationSource requestCollection)    at System.Web.HttpRequest.ValidateNameValueCollection(NameValueCollection nvc, RequestValidationSource requestCollection)    at System.Web.HttpRequest.get_Form()    at System.Web.HttpRequest.get_HasForm()    at System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull)    at System.Web.UI.Page.DeterminePostBackMode()    at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)    at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)    at System.Web.UI.Page.ProcessRequest()    at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context)    at System.Web.UI.Page.ProcessRequest(HttpContext context)    at ASP.displaypost_aspx.ProcessRequest(HttpContext context) in c:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\a37c2f81\cfc4c927\App_Web_i2rujncl.9.cs:line 0    at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()    at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) What is the Cause? In ASP.NET 4, by default, request validation is enabled for all requests, because it is enabled before the BeginRequest phase of an HTTP request. As a result, request validation applies to requests for all ASP.NET resources, not just .aspx page requests. This includes requests such as Web service calls and custom HTTP handlers. Request validation is also active when custom HTTP modules are reading the contents of an HTTP request. Solution: To revert to the behavior of the ASP.NET 2.0 request validation feature, add the following setting in the Web.config file: <system.web>  <httpRuntime requestValidationMode=”2.0? /> </system.web>

  • Open Source WPF UML Design tool

    - by oazabir
    PlantUmlEditor is my new free open source UML designer project built using WPF and .NET 3.5. If you have used plantuml before, you know that you can quickly create sophisitcated UML diagrams without struggling with a designer. Especially those who use Visio to draw UML diagrams (God forbid!), you will be at heaven. This is a super fast way to get your diagrams up and ready for show. You can *write* UML diagrams in plain English, following a simple syntax and get diagrams generated on-the-fly. This editor really saves time designing UML diagrams. I have to produce quick diagrams to convey ideas quickly to Architects, Designers and Developers everyday. So, I use this tool to write some quick diagrams at the speed of coding, and the diagrams get generated on the fly. Instead of writing a long mail explaining some complex operation or some business process in English, I can quickly write it in the editor in almost plain English, and get a nice looking activity/sequence diagram generated instantly. Making major changes is also as easy as doing search-replace and copy-pasting blocks here and there. You don't get such agility in any conventional mouse-based UML designers. I have submited a full codeproject article to give you a detail walkthrough how I have built this. Please read this article and vote for me if you like it. PlantUML Editor: A fast and simple UML editor using WPF http://www.codeproject.com/KB/smart/plantumleditor.aspx You can download the project from here: http://code.google.com/p/plantumleditor/

  • Game Design Dilemma

    - by Chris Williams
    I'm working on a 2d tilemapped RPG. I've actually made quite a fair amount of progress, but I'm at a point where I need to make a UI decision. I have the overland world completely mapped out, and I have several towns and special areas. I'm on the fence about how to integrate the two. Scenario 1: I have one ginormous map, where everything is the same scale. This means you can walk in and out of towns without having to load or wait and transition in any way. With everything the same scale, movement costs the same no matter where you are (in terms of time/turns/energy/hunger/whatever/etc...)  The potential downside to this is that it could take quite a long time to get anywhere on foot. Scenario 2: I have an overland map, a set of town maps, overland tactical maps, dungeon maps & special area maps. The overland map is at a different scale than the other maps. This means that time/turns/energy/hunger/whatever/etc is calculated at a different rate than on the other maps, which have a 1:1 scale. When entering a town, dungeon, special area or having a random encounter, you would effectively zoom in from the overland scale to the tactical scale. When you are done with combat, or exit a dungeon or town, it would zoom back out to the overland map. The downside to this is that at the zoomed out scale, the overland map isn't all that big (comparitively) and you can traverse it fairly quickly (in real time, not game world time.) Options: 1) Go with scenario 1, as is. 2) Go with scenario 1 and introduce a slightly speedier version of overland travel, such as a horse. 3) Go with scenario 1 and introduce "instant" travel, via portals or some kind of "click the big map" mechanism. This would only work with places you've already been, or somehow unlocked (perhaps via a quest.) 4) Go with Scenario 2, as is.   Thoughts, opinions, suggestions?  Feedback appreciated.

  • Day 2 - Game Design Documentation

    - by dapostolov
    So yesterday I didn't cut any code for my game but I was able to do a tiny bit of research on the XNA Game Development Technology and the communities out there and do you know what? I feel I'm a bit closer to my goal. The bad news is today I didn't cut code either. However, not all is lost because I wanted to get my ideas on paper and today I just did that.  Today, I began to jot down notes about the game and how I felt the visual elements would interact with each other. Unlike my workplace, my personal level of documentation is nothing more than a task list or a mind map of my ideas; it helps me streamline my solutions quiet effectively and circumvent the long process of articulating each thought to the n-th degree. I truly dislike documentation (because I have an extremely hard time articulating my thought and solutions); however, because I tend to do a really good job with documentation I tend to get stuck writing the buggers. But as a generalist remark: 'No Developer likes documentation.' For now let's stick with my basic notes and call this post a living document. Here are my notes, fresh, from after watching the new first episode of Merlin second season! Actually, a quick recommendation to anyone who is reading this (if anyone is): I truly recommend you envelope yourself in the medium or task you're trying to tackle. Be one with moment and feel it! For instance: Are you writing a fantasy script / game? What would the music of the genre sound like? For me the Conan the Barbarian soundtrack by Basil Poledouris is frackin awesome. There are many other good CD's out there, which I listen to (some who even use medival instruments, but Conan I keep returning to. It's a creative trigger for me. Ask yourself what would the imagery look like? Time to surf google for artist renditions of fantasy! What would the game feel like? Start playing some of your favorite games that inspire you, be wary though, have some self control and don't let it absorb your time. Anyhow, onto the documentation... Screens, Scenes, and Sprites. Oh My! (groan...) The first thing that came to mind were the screens, I thought the following would suffice: Menu Screen Character Customisation Screen Loading Screen? Battle Ground The Menu Screen Ok. So, the thought here is when the game loads a huge title is displayed: Wizard Wars. The player is prompted with 3 menu items: 1 Player Game, 2 Player Game, and Exit. Since I'm targetting the PC platform, as a non-networked game to start, I picture myself running my mouse over each menu option and the visual element of the menu item changes, along with a sound to indicate that I am over a curent menu item. And as I move my mouse away, it changes back, and possibly an exit mouse sound. Maybe on the screen somewhere is a brazier alit with a magical tome open right beside it, OR, maybe the tome is the menu! I hear the menu music as mellow, not obtrusive or piercing. On a menu item select, a confirmation sound bellows to indicate the players selection. The Esc key will always return me to the previous screens or desktop. The menu screen must feel...dark, like a really important ritual is about to happen and thus the music should build up. 1 Player Game - > Customize Character(s) 2 Player Game - > Customize Character(s) Exit - > Back to Windows Notes: So the first thing I pick up here are a couple things: First and foremost, my artistic abilities suck crap, so I may have to hire an artist (now that i've said that, lets get techy) graphical objects will be positioned within a scene on each screen / window. Menu items will be represented grapically, possibly animated, and have sound / animation effects triggered by user input or a time line. I have an animated scene involving a brazier or fire on a stick IF I was to move this game to the xbox, I'd have to track which menu item is currently selected (unless I do a mouse pointer type thing.) WindowObject has a scene A Scene has many GameObjects GameObject has a position graphic or animation MenuObject is a GameObject which has a mouse in, mouse out, and click event which either does something graphically (animation), does something with sound, or moves to another screen.  Character Customisation Screen With either the 1 or 2 player option selected, both selections will come to this screen; a wizard requires a name, powers, and vestements of course! Player one will configure his character first and then player two. I considered a split screen for PC but to have two people fighting over a keyboard would probably suck. For XBox, a split screen could work; maybe when I get into the networking portion (phase 2 blog?) of this game I will remove the 2 player option for PC and provide only multiplayer and I will leave 2 player for xbox...hmm... Anyhow...I picture the creation process as follows: Name: (textbox / keyboard entry) - for xbox, this would have to be different. Robe Color: (color box, or something) Stats: Speed, Oomph, and Health. (as sliders) 1 as minimum and 10 as maximum. Ok, Back, and Cancel buttons / options. Each stat has a benefit which are listed below. The idea is the player decides if he wants his wizard to run fast, be a tank and ... hit with a purse.Regardless, the player will have a pool of 12 points to use. Ideally, A balanced wizard will have 5 in each attribute. Spells? The only spell of choice is a ball of fire which comes without question. The music and screen should still feel like a ritual. The Character Speed Basically, how fast your character moves and casts. Oomph (Best Monster Truck Voice): PURE POWAH!!! The damage output of your fireball. Health How much damage you can take. Notes: I realise the game dynamics may sound uninteresting at the moment; but I think after a couple releases, we could have some other grand ideas such as: saved profiles, gold to upgrade arsenal of spells, talents, etc...but for now...a vanilla fireball thrower mage will suffice for this experiment. OK. So... a MenuObject  may need to be loosely coupled to allow future items such as networking? may be a button? a CharacterObject has a name speed oomph health and a funky robe color. cap on the three stats (1-10) an arsenal of 1 spell (possibly could expand this) The Loading Screen As is. The Battleground Screen For now, I'm keeping the screen as max resolution for the PC. The screen isn't going to move or even be a split screen. I'm not aiming high here because I want to see what level of change is involved when new features / concepts are added to game content. I'm interested to find out if we could apply techniques such as MVC or MVVM to this type of development or is it too tightly coupled? This reminds me when when my best friend and I were brainstorming our game idea (this is going back a while...1994, 6?) and he cringed at the thought of bringing business technology into games, especially when I suggested a database to store character information and COM / DCOM as the medium, but it seems I wasn't far off (reflecting); just like his implementation of a xml "config file" for dynamic direct-x menus back before .net in 1999...anyhow...i digress... The Battle One screen, two characters lobing balls of fire at each other...It doesn't get better than that. Every so often a scroll appears...and the fireballs bounce off walls, or the wizard has rapid fire, or even scrolls of healing! The scroll options are endless. Two bars at the top, each the color of the wizard (with their name beside the bar) indicate how much health they have. Possibly the appearance of the scrolls means the battle is taking too long? I'm thinking 1 player controls: up, down, left, right and space to fire the button. Or even possibly, mouse click and shift - mouse button to fire a spell in the direction they are facing. Two player controls: a, s, d, f and space AND arrows (up, down, left, right) and Del key or Crtl. The game ends when a player has 0 health and a dialog box appears asking for a rematch / reconfigure / exit. Health goes down when a fireball (friendly or not), connects with a wizard. When a wizard connects with a scroll, a countdown clock / icon appears near the health bar and the wizard begins to glow. For the most part, a wizard can have only scroll 1 effect on him at a time. Notes: Ok, there's alot to cover here. a CharacterObject is a GameObject it travels at a set velocity it travels in a direction it has sounds (walking, running, casting, impact, dying, laughing, whistling, other?) it has animations (walking, running, casting, impact, dying, laughing, idle, other?) it has a lifespan (determined by health) it is alive or dead it has a position a ScrollObject is a GameObject it carries a transferance of points "damage" (or healing, bad scroll effect?) (determinde by caster) it carries a transferance of "other" it is stationary it has a sound on impact it has a stationary animation it has an impact animation / or transfers an impact animation it has a fade animation? it has a lifespan (determined by game) it is alive or dead it has a position a WallObject is a GameObject it has a sound on fireball impact? it is a still image / stationary it has an impact animation / or transfers an impact animation it is dead it has a position A FireBall is a GameObject it carries a transferance of poinst "damage" (or healing, bad scroll effect?) (determinde by caster) it travels at a set velocity it travels in a direction it has a sound it has a travel animation it has an impact animation / or transfers an impact animation it has a fade animation? it has a lifespan (determined by caster) it is alive or dead it has a position As I look at this, I can see some common attributes in each object that I can carry up to the GameObject. I think I'm going to end the documentation here, it's taken me a bit of time to type this all out, tomorrow. I'll load up my IDE and my paint studio to get some good old fashioned cowboy hacking going!   D.

  • ASP.NET AppDomain–What it is and why it’s important–Part 12 of 52 part series

    - by OWScott
    AppDomains are a silent mysterious part of ASP.NET and IIS.  It’s important for the web administrator to be aware of this building block of ASP.NET so that we can be aware of how changes to the system can affect production sites. While this series is targeted at the IIS and web administrator, this topic is useful for the ASP.NET programmer too. This is week 12 of a 52 week series on various web administration related tasks. Past and future videos can be found here.

  • MVC Portable Areas &ndash; Web Application Projects

    - by Steve Michelotti
    This is the first post in a series related to build and deployment considerations as I’ve been exploring MVC Portable Areas: #1 – Using Web Application Project to build portable areas #2 – Conventions for deploying portable area static files #3 – Portable area static files as embedded resources Portable Areas is a relatively new feature available in MvcContrib that builds upon the new feature called Areas that was introduced in MVC 2. In short, portable areas provide a way to distribute MVC binary components as simple .NET assemblies rather than an assembly along with all the physical files for the views. At the heart of portable areas is a custom view engine that delivers the *.aspx pages by pulling them from embedded resources rather than from the physical file system. A portable area can be something as small as a tiny snippet of html that eventually gets rendered on a page, to something as large as an entire MVC web application. You should read this 4-part series to get up to speed on what portable areas are. Web Application Project In most of the posts to date, portable areas are shown being created with a simple C# class library. This is cool and it serves as an effective way to illustrate the simplicity of portable areas. However, the problem with that is that the developer loses out on the normal developer experience with the various tooling/scaffolding options that we’ve come to expect in visual studio like the ability to add controllers, views, etc. easily: I’ve had good results just using a normal web application project (rather than a class library) to develop portable areas and get the normal vs.net benefits. However, one gotcha that comes as a result is that it’s easy to forget to set the file to “Embedded Resource” every time you add a new aspx page. To mitigate this, simply add this MSBuild snippet shown below to your *.csproj file and all *.aspx, *ascx will automatically be set as embedded resources when your project compiles: 1: <Target Name="BeforeBuild"> 2: <ItemGroup> 3: <EmbeddedResource Include="**\*.aspx;**\*.ascx" /> 4: </ItemGroup> 5: </Target> Also, you should remove the Global.asax from this web application as it is not the host. Being able to have the normal tooling experience we’ve come to expect from Visual Studio makes creating portable areas quite simple. This even allows us to do things like creating a project template such as “MVC Portable Area Web Application” that would come pre-configured with routes set up in the PortableAreaRegistration and no Global.asax file.

  • Error: The base type 'System.Web.UI.MasterPage' is not allowed for this page

    - by Patrick Olurotimi Ige
    I came across this error when i was trying to ajaxify my sharepoint site. After adding the AjaxifyMoss from the codeplex  developed by Richard Finn. And tried loading my site i got the error Error: The base type 'System.Web.UI.MasterPage' is not allowed for this page So  i decided to check the web.config and i noticed the SafeControl tag doesn't have the .Net 2.0 assembly included despite the fact i added both vsersios 2.0 and 3.5. Its possible the.Net  3.5 assebply overwrote the 2.0. Anyway after i added the below which is the 2.0 verison       <SafeControl Assembly="System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" Namespace="System.Web.UI" TypeName="*" Safe="True" AllowRemoteDesigner="True" />  And refreshed my page.

  • Overwriting TFS Web Services

    - by javarg
    In this blog I will share a technique I used to intercept TFS Web Services calls. This technique is a very invasive one and requires you to overwrite default TFS Web Services behavior. I only recommend taking such an approach when other means of TFS extensibility fail to provide the same functionality (this is not a supported TFS extensibility point). For instance, intercepting and aborting a Work Item change operation could be implemented using this approach (consider TFS Subscribers functionality before taking this approach, check Martin’s post about subscribers). So let’s get started. The technique consists in versioning TFS Web Services .asmx service classes. If you look into TFS’s ASMX services you will notice that versioning is supported by creating a class hierarchy between different product versions. For instance, let’s take the Work Item management service .asmx. Check the following .asmx file located at: %Program Files%\Microsoft Team Foundation Server 2010\Application Tier\Web Services\_tfs_resources\WorkItemTracking\v3.0\ClientService.asmx The .asmx references the class Microsoft.TeamFoundation.WorkItemTracking.Server.ClientService3: <%-- Copyright (c) Microsoft Corporation. All rights reserved. --%> <%@ webservice language="C#" Class="Microsoft.TeamFoundation.WorkItemTracking.Server.ClientService3" %> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } The inheritance hierarchy for this service class follows: Note the naming convention used for service versioning (ClientService3, ClientService2, ClientService). We will need to overwrite the latest service version provided by the product (in this case ClientService3 for TFS 2010). The following example intercepts and analyzes WorkItem fields. Suppose we need to validate state changes with more advanced logic other than the provided validations/constraints of the process template. Important: Backup the original .asmx file and create one of your own. Create a Visual Studio Web App Project and include a new ASMX Web Service in the project Add the following references to the project (check the folder %Program Files%\Microsoft Team Foundation Server 2010\Application Tier\Web Services\bin\): Microsoft.TeamFoundation.Framework.Server.dll Microsoft.TeamFoundation.Server.dll Microsoft.TeamFoundation.Server.dll Microsoft.TeamFoundation.WorkItemTracking.Client.QueryLanguage.dll Microsoft.TeamFoundation.WorkItemTracking.Server.DataAccessLayer.dll Microsoft.TeamFoundation.WorkItemTracking.Server.DataServices.dll Replace the default service implementation with the something similar to the following code: Code Snippet /// <summary> /// Inherit from ClientService3 to overwrite default Implementation /// </summary> [WebService(Namespace = "http://schemas.microsoft.com/TeamFoundation/2005/06/WorkItemTracking/ClientServices/03", Description = "Custom Team Foundation WorkItemTracking ClientService Web Service")] public class CustomTfsClientService : ClientService3 {     [WebMethod, SoapHeader("requestHeader", Direction = SoapHeaderDirection.In)]     public override bool BulkUpdate(         XmlElement package,         out XmlElement result,         MetadataTableHaveEntry[] metadataHave,         out string dbStamp,         out Payload metadata)     {         var xe = XElement.Parse(package.OuterXml);         // We only intercept WorkItems Updates (we can easily extend this sample to capture any operation).         var wit = xe.Element("UpdateWorkItem");         if (wit != null)         {             if (wit.Attribute("WorkItemID") != null)             {                 int witId = (int)wit.Attribute("WorkItemID");                 // With this Id. I can query TFS for more detailed information, using TFS Client API (assuming the WIT already exists).                 var stateChanged =                     wit.Element("Columns").Elements("Column").FirstOrDefault(c => (string)c.Attribute("Column") == "System.State");                 if (stateChanged != null)                 {                     var newStateName = stateChanged.Element("Value").Value;                     if (newStateName == "Resolved")                     {                         throw new Exception("Cannot change state to Resolved!");                     }                 }             }         }         // Finally, we call base method implementation         return base.BulkUpdate(package, out result, metadataHave, out dbStamp, out metadata);     } } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } 4. Build your solution and overwrite the original .asmx with the new implementation referencing our new service version (don’t forget to backup it up first). 5. Copy your project’s .dll into the following path: %Program Files%\Microsoft Team Foundation Server 2010\Application Tier\Web Services\bin 6. Try saving a WorkItem into the Resolved state. Enjoy!

  • ASP.NET Web API - Screencast series with downloadable sample code - Part 1

    - by Jon Galloway
    There's a lot of great ASP.NET Web API content on the ASP.NET website at http://asp.net/web-api. I mentioned my screencast series in original announcement post, but we've since added the sample code so I thought it was worth pointing the series out specifically. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. So - let's watch them together! Grab some popcorn and pay attention, because these are short. After each video, I'll talk about what I thought was important. I'm embedding the videos using HTML5 (MP4) with Silverlight fallback, but if something goes wrong or your browser / device / whatever doesn't support them, I'll include the link to where the videos are more professionally hosted on the ASP.NET site. Note also if you're following along with the samples that, since Part 1 just looks at the File / New Project step, the screencast part numbers are one ahead of the sample part numbers - so screencast 4 matches with sample code demo 3. Note: I started this as one long post for all 6 parts, but as it grew over 2000 words I figured it'd be better to break it up. Part 1: Your First Web API [Video and code on the ASP.NET site] This screencast starts with an overview of why you'd want to use ASP.NET Web API: Reach more clients (thinking beyond the browser to mobile clients, other applications, etc.) Scale (who doesn't love the cloud?!) Embrace HTTP (a focus on HTTP both on client and server really simplifies and focuses service interactions) Next, I start a new ASP.NET Web API application and show some of the basics of the ApiController. We don't write any new code in this first step, just look at the example controller that's created by File / New Project. using System; using System.Collections.Generic; using System.Linq; using System.Net.Http; using System.Web.Http; namespace NewProject_Mvc4BetaWebApi.Controllers { public class ValuesController : ApiController { // GET /api/values public IEnumerable<string> Get() { return new string[] { "value1", "value2" }; } // GET /api/values/5 public string Get(int id) { return "value"; } // POST /api/values public void Post(string value) { } // PUT /api/values/5 public void Put(int id, string value) { } // DELETE /api/values/5 public void Delete(int id) { } } } Finally, we walk through testing the output of this API controller using browser tools. There are several ways you can test API output, including Fiddler (as described by Scott Hanselman in this post) and built-in developer tools available in all modern browsers. For simplicity I used Internet Explorer 9 F12 developer tools, but you're of course welcome to use whatever you'd like. A few important things to note: This class derives from an ApiController base class, not the standard ASP.NET MVC Controller base class. They're similar in places where API's and HTML returning controller uses are similar, and different where API and HTML use differ. A good example of where those things are different is in the routing conventions. In an HTTP controller, there's no need for an "action" to be specified, since the HTTP verbs are the actions. We don't need to do anything to map verbs to actions; when a request comes in to /api/values/5 with the DELETE HTTP verb, it'll automatically be handled by the Delete method in an ApiController. The comments above the API methods show sample URL's and HTTP verbs, so we can test out the first two GET methods by browsing to the site in IE9, hitting F12 to bring up the tools, and entering /api/values in the URL: That sample action returns a list of values. To get just one value back, we'd browse to /values/5: That's it for Part 1. In Part 2 we'll look at getting data (beyond hardcoded strings) and start building out a sample application.

  • What is "The" book for database design?

    - by FarmBoy
    In programming, there is often a canonical book for a particular topic, like the dragon book for compilers, K&R for C, etc. Is their a book regarding modern database design that simply must be read by anyone that would hope to eventually design databases? I'm not looking for a bunch of recommendations here. The answer I'm looking for is either "Yes, it's [Title, author]." or "No, there are many good books on databases, but no one must-read."

  • Installing SubText with Web PI

    - by Ben Griswold
    SubText is the engine behind our company blog. With the goal of ensuring a smooth transition between the main website and the blogs, I spent some time tightening up the styles for the aggregate and individual blogs last week.  This required a custom SubText skin and lot of css tweaking. Though I’ve previously had the SubText source running on my machine, there was no need to update or rebuild the solution in my current case so just went ahead with a local installation using the Microsoft Web Platform Installer (Web PI).  I just checked the SubText box, provided answers to a few key setup questions (admin user credentials, SubText database, etc) and I was up and running in minutes.   Once the setup was complete, I was asked if I’d like to launch SubText.  The SubText Installation Wizard picked up where Web PI left off and the setup couldn’t have been easier.  Web PI provides quick and easy installs for lots of goodies.  Check it out.

  • Integrate BING API for Search inside ASP.Net web application

    - by sreejukg
    As you might already know, Bing is the Microsoft Search engine and is getting popular day by day. Bing offers APIs that can be integrated into your website to increase your website functionality. At this moment, there are two important APIs available. They are Bing Search API Bing Maps The Search API enables you to build applications that utilize Bing’s technology. The API allows you to search multiple source types such as web; images, video etc. and supports various output prototypes such as JSON, XML, and SOAP. Also you will be able to customize the search results as you wish for your public facing website. Bing Maps API allows you to build robust applications that use Bing Maps. In this article I am going to describe, how you can integrate Bing search into your website. In order to start using Bing, First you need to sign in to http://www.bing.com/toolbox/bingdeveloper/ using your windows live credentials. Click on the Sign in button, you will be asked to enter your windows live credentials. Once signed in you will be redirected to the Developer page. Here you can create applications and get AppID for each application. Since I am a first time user, I don’t have any applications added. Click on the Add button to add a new application. You will be asked to enter certain details about your application. The fields are straight forward, only thing you need to note is the website field, here you need to enter the website address from where you are going to use this application, and this field is optional too. Of course you need to agree on the terms and conditions and then click Save. Once you click on save, the application will be created and application ID will be available for your use. Now we got the APP Id. Basically Bing supports three protocols. They are JSON, XML and SOAP. JSON is useful if you want to call the search requests directly from the browser and use JavaScript to parse the results, thus JSON is the favorite choice for AJAX application. XML is the alternative for applications that does not support SOAP, e.g. flash/ Silverlight etc. SOAP is ideal for strongly typed languages and gives a request/response object model. In this article I am going to demonstrate how to search BING API using SOAP protocol from an ASP.Net application. For the purpose of this demonstration, I am going to create an ASP.Net project and implement the search functionality in an aspx page. Open Visual Studio, navigate to File-> New Project, select ASP.Net empty web application, I named the project as “BingSearchSample”. Add a Search.aspx page to the project, once added the solution explorer will looks similar to the following. Now you need to add a web reference to the SOAP service available from Bing. To do this, from the solution explorer, right click your project, select Add Service Reference. Now the new service reference dialog will appear. In the left bottom of the dialog, you can find advanced button, click on it. Now the service reference settings dialog will appear. In the bottom left, you can find Add Web Reference button, click on it. The add web reference dialog will appear now. Enter the URL as http://api.bing.net/search.wsdl?AppID=<YourAppIDHere>&version=2.2 (replace <yourAppIDHere> with the appID you have generated previously) and click on the button next to it. This will find the web service methods available. You can change the namespace suggested by Bing, but for the purpose of this demonstration I have accepted all the default settings. Click on the Add reference button once you are done. Now the web reference to Search service will be added your project. You can find this under solution explorer of your project. Now in the Search.aspx, that you previously created, place one textbox, button and a grid view. For the purpose of this demonstration, I have given the identifiers (ID) as txtSearch, btnSearch, gvSearch respectively. The idea is to search the text entered in the text box using Bing service and show the results in the grid view. In the design view, the search.aspx looks as follows. In the search.aspx.cs page, add a using statement that points to net.bing.api. I have added the following code for button click event handler. The code is very straight forward. It just calls the service with your AppID, a query to search and a source for searching. Let us run this page and see the output when I enter Microsoft in my textbox. If you want to search a specific site, you can include the site name in the query parameter. For e.g. the following query will search the word Microsoft from www.microsoft.com website. searchRequest.Query = “site:www.microsoft.com Microsoft”; The output of this query is as follows. Integrating BING search API to your website is easy and there is no limit on the customization of the interface you can do. There is no Bing branding required so I believe this is a great option for web developers when they plan for site search.
