• Porting Ruby/NCruses Rogue-Like to .NET and FlatRedBall

  - by ashes999

  I created an awesome rogue-like game in Ruby. For the GUI, I used NCurses. Since I'm using FlatRedBall as my engine of choice for Silverlight game development, I want to port this game over. What is the best way to efficiently doing this, and what are the pitfalls I should expect? For example, Ruby is object-oriented, like C#, and I should be able to just convert (rewrite) classes one by one. However, I will run into issues like: NCurses API. I need to possibly create my own notions of a "Window", or else rewrite GUI code. It's one class, but it's BIG. Mix-Ins. These are essentially aspect-oriented development. There are a couple of solutions in .NET, like dynamic classes. What else? Also, I should mention that I want to create a C# application out of this. As much as possible, I'll dump reusable and helper code, algorithms, etc. into separate projects and generate reusable DLLs.

• C#/.NET Little Wonders: Skip() and Take()

  - by James Michael Hare

  Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. I’ve covered many valuable methods from System.Linq class library before, so you already know it’s packed with extension-method goodness.  Today I’d like to cover two small families I’ve neglected to mention before: Skip() and Take().  While these methods seem so simple, they are an easy way to create sub-sequences for IEnumerable<T>, much the way GetRange() creates sub-lists for List<T>. Skip() and SkipWhile() The Skip() family of methods is used to ignore items in a sequence until either a certain number are passed, or until a certain condition becomes false.  This makes the methods great for starting a sequence at a point possibly other than the first item of the original sequence.   The Skip() family of methods contains the following methods (shown below in extension method syntax): Skip(int count) Ignores the specified number of items and returns a sequence starting at the item after the last skipped item (if any).  SkipWhile(Func<T, bool> predicate) Ignores items as long as the predicate returns true and returns a sequence starting with the first item to invalidate the predicate (if any).  SkipWhile(Func<T, int, bool> predicate) Same as above, but passes not only the item itself to the predicate, but also the index of the item.  For example: 1: var list = new[] { 3.14, 2.72, 42.0, 9.9, 13.0, 101.0 }; 2:  3: // sequence contains { 2.72, 42.0, 9.9, 13.0, 101.0 } 4: var afterSecond = list.Skip(1); 5: Console.WriteLine(string.Join(", ", afterSecond)); 6:  7: // sequence contains { 42.0, 9.9, 13.0, 101.0 } 8: var afterFirstDoubleDigit = list.SkipWhile(v => v < 10.0); 9: Console.WriteLine(string.Join(", ", afterFirstDoubleDigit)); Note that the SkipWhile() stops skipping at the first item that returns false and returns from there to the rest of the sequence, even if further items in that sequence also would satisfy the predicate (otherwise, you’d probably be using Where() instead, of course). If you do use the form of SkipWhile() which also passes an index into the predicate, then you should keep in mind that this is the index of the item in the sequence you are calling SkipWhile() from, not the index in the original collection.  That is, consider the following: 1: var list = new[] { 1.0, 1.1, 1.2, 2.2, 2.3, 2.4 }; 2:  3: // Get all items < 10, then 4: var whatAmI = list 5: .Skip(2) 6: .SkipWhile((i, x) => i > x); For this example the result above is 2.4, and not 1.2, 2.2, 2.3, 2.4 as some might expect.  The key is knowing what the index is that’s passed to the predicate in SkipWhile().  In the code above, because Skip(2) skips 1.0 and 1.1, the sequence passed to SkipWhile() begins at 1.2 and thus it considers the “index” of 1.2 to be 0 and not 2.  This same logic applies when using any of the extension methods that have an overload that allows you to pass an index into the delegate, such as SkipWhile(), TakeWhile(), Select(), Where(), etc.  It should also be noted, that it’s fine to Skip() more items than exist in the sequence (an empty sequence is the result), or even to Skip(0) which results in the full sequence.  So why would it ever be useful to return Skip(0) deliberately?  One reason might be to return a List<T> as an immutable sequence.  Consider this class: 1: public class MyClass 2: { 3: private List<int> _myList = new List<int>(); 4:  5: // works on surface, but one can cast back to List<int> and mutate the original... 6: public IEnumerable<int> OneWay 7: { 8: get { return _myList; } 9: } 10:  11: // works, but still has Add() etc which throw at runtime if accidentally called 12: public ReadOnlyCollection<int> AnotherWay 13: { 14: get { return new ReadOnlyCollection<int>(_myList); } 15: } 16:  17: // immutable, can't be cast back to List<int>, doesn't have methods that throw at runtime 18: public IEnumerable<int> YetAnotherWay 19: { 20: get { return _myList.Skip(0); } 21: } 22: } This code snippet shows three (among many) ways to return an internal sequence in varying levels of immutability.  Obviously if you just try to return as IEnumerable<T> without doing anything more, there’s always the danger the caller could cast back to List<T> and mutate your internal structure.  You could also return a ReadOnlyCollection<T>, but this still has the mutating methods, they just throw at runtime when called instead of giving compiler errors.  Finally, you can return the internal list as a sequence using Skip(0) which skips no items and just runs an iterator through the list.  The result is an iterator, which cannot be cast back to List<T>.  Of course, there’s many ways to do this (including just cloning the list, etc.) but the point is it illustrates a potential use of using an explicit Skip(0). Take() and TakeWhile() The Take() and TakeWhile() methods can be though of as somewhat of the inverse of Skip() and SkipWhile().  That is, while Skip() ignores the first X items and returns the rest, Take() returns a sequence of the first X items and ignores the rest.  Since they are somewhat of an inverse of each other, it makes sense that their calling signatures are identical (beyond the method name obviously): Take(int count) Returns a sequence containing up to the specified number of items. Anything after the count is ignored. TakeWhile(Func<T, bool> predicate) Returns a sequence containing items as long as the predicate returns true.  Anything from the point the predicate returns false and beyond is ignored. TakeWhile(Func<T, int, bool> predicate) Same as above, but passes not only the item itself to the predicate, but also the index of the item. So, for example, we could do the following: 1: var list = new[] { 1.0, 1.1, 1.2, 2.2, 2.3, 2.4 }; 2:  3: // sequence contains 1.0 and 1.1 4: var firstTwo = list.Take(2); 5:  6: // sequence contains 1.0, 1.1, 1.2 7: var underTwo = list.TakeWhile(i => i < 2.0); The same considerations for SkipWhile() with index apply to TakeWhile() with index, of course.  Using Skip() and Take() for sub-sequences A few weeks back, I talked about The List<T> Range Methods and showed how they could be used to get a sub-list of a List<T>.  This works well if you’re dealing with List<T>, or don’t mind converting to List<T>.  But if you have a simple IEnumerable<T> sequence and want to get a sub-sequence, you can also use Skip() and Take() to much the same effect: 1: var list = new List<double> { 1.0, 1.1, 1.2, 2.2, 2.3, 2.4 }; 2:  3: // results in List<T> containing { 1.2, 2.2, 2.3 } 4: var subList = list.GetRange(2, 3); 5:  6: // results in sequence containing { 1.2, 2.2, 2.3 } 7: var subSequence = list.Skip(2).Take(3); I say “much the same effect” because there are some differences.  First of all GetRange() will throw if the starting index or the count are greater than the number of items in the list, but Skip() and Take() do not.  Also GetRange() is a method off of List<T>, thus it can use direct indexing to get to the items much more efficiently, whereas Skip() and Take() operate on sequences and may actually have to walk through the items they skip to create the resulting sequence.  So each has their pros and cons.  My general rule of thumb is if I’m already working with a List<T> I’ll use GetRange(), but for any plain IEnumerable<T> sequence I’ll tend to prefer Skip() and Take() instead. Summary The Skip() and Take() families of LINQ extension methods are handy for producing sub-sequences from any IEnumerable<T> sequence.  Skip() will ignore the specified number of items and return the rest of the sequence, whereas Take() will return the specified number of items and ignore the rest of the sequence.  Similarly, the SkipWhile() and TakeWhile() methods can be used to skip or take items, respectively, until a given predicate returns false.    Technorati Tags: C#, CSharp, .NET, LINQ, IEnumerable<T>, Skip, Take, SkipWhile, TakeWhile

• Uganda .NET Usergroup April meeting

  - by Malisa L. Ncube

  Our April meeting was presented by Wilson Kutegeka on the topic of Building the Data Access a layer. In his presentation he showed a tool which he has developed to generate the entities, stores procedures that would be used to reduce having to retype the same boilerplate code for each entity. He uses visual basic samples to demonstrate access to the data from the database and inherits his classes from an abstract class which contains common properties including connection strings, save and delete methods. A number of questions emerged from the group, mostly those that use a business model based approaches. Some of the questions are on unit testing and mocking the models without using the database, the use of IoCs and loose coupled patterns. Some of the questions were on caching, Linq support and data annotations based validation. The presentation details can be found here. Intellisense LTD agreed to sponsor our website and we are glad to have that as we really need to have a website running. We would like to thank the following companies for supporting our community activities: Apress, Telerik, Manning, DevExpress (CodeRush), Ncover, and Intellisense.   Technorati Tags: Uganda .NET Usergroup

• .NET vs Windows 8: Rematch!

  - by Simon Cooper

  So, although you will be able to use your existing .NET skills to develop Metro apps, it turns out Microsoft are limiting Visual Studio 2011 Express to Metro-only. From the Express website: Visual Studio 11 Express for Windows 8 provides tools for Metro style app development. To create desktop apps, you need to use Visual Studio 11 Professional, or higher. Oh dear. To develop any sort of non-Metro application, you will need to pay for at least VS Professional. I suspect Microsoft (or at least, certain groups within Microsoft) have a very explicit strategy in mind. By making VS Express Metro-only, developers who don't want to pay for Professional will be forced to make their simple one-shot or open-source application in Metro. This increases the number of applications available for Windows 8 and Windows mobile devices, which in turn make those platforms more attractive for consumers. When you use the free VS 11 Express, instead of paying Microsoft, you provide them a service by making applications for Metro, which in turn makes Microsoft's mobile offering more attractive to consumers, increasing their market share. Of course, it remains to be seen if developers forced to jump onto the Metro bandwagon will simply jump ship to Android or iOS instead. At least, that's what I think is going on. With Microsoft, who really knows?

• Web.NET event coming in October

  - by Chris Massey

  If you’re a web developer in Europe (or would like an excuse to travel to Europe), you should definitely take a look at the Web.NET event coming in October. It’s being organized by two Italian web maestros (Simone Chiaretta and Ugo Lattanzi) and the session list looks fantastic. The event site pretty much speaks for itself, but here’s a quick version: It’s a free one-day event on October 20th, with a huge variety of great sessions by great speakers, all 100% focused on web development. There’s a pizza-fuelled hackathon in the evening; thrills, spills and hot new skills. It’s a great chance to network with the local (in relative terms) web development community. It’s free (although all donations are very greatly appreciated). It’s in Milan, darling. Here’s what you need to do: Go and register on www.webnetconf.eu, and vote on which sessions you think look the most interesting. I know this will be a difficult process – it’s *very* hard to choose – but persevere! Grab your place when the free tickets become available early next month (places are limited). Come to Milan in October, learn some new skills, meet some great people, and maybe build something awesome if you feel like staying up late. I’ll be there, and hopefully I’ll see you on the day.

• Differences when Running with OutputCache managed module under ASP.NET IIS7.x with Cache-control header

  - by Shawn Cicoria

  This post is to report some differences when using MVC or IHttpHandlers if you’re attempting to set the Cache-control : max-age or s-maxage value under IIS7.x using the HttpResponse.Cache methods. [UPDATE]: 2011-3-14 – The missing piece was calling  Response.Cache.SetSlidingExpiration(true) as follows: context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); context.Response.ContentType = "image/jpeg"; context.Response.Cache.SetSlidingExpiration(true);   Under IIS7.x if you us one of the following 2 methods, you will only get a Cache-ability of “public”.  public ActionResult Image2() { MemoryStream oStream = new MemoryStream(); using (Bitmap obmp = ImageUtil.RenderImage("Respone.Cache.Setxx calls", 5, DateTime.Now)) { obmp.Save(oStream, ImageFormat.Jpeg); oStream.Position = 0; Response.Cache.SetCacheability(HttpCacheability.Public); Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); return new FileStreamResult(oStream, "image/jpeg"); } } Method 2 – which is just a plain old HttpHandler and really isn’t MVC3, but under the same MVC ASP.NET application, same result. public class image : IHttpHandler { public void ProcessRequest(HttpContext context) { using (var image = ImageUtil.RenderImage("called from IHttpHandler direct", 5, DateTime.Now)) { context.Response.Cache.SetCacheability(HttpCacheability.Public); context.Response.Cache.SetMaxAge(TimeSpan.FromMinutes(5)); context.Response.ContentType = "image/jpeg"; image.Save(context.Response.OutputStream, ImageFormat.Jpeg); } } } Using the following under MVC3 (I haven’t tried under earlier versions) will work by applying the OutputCacheAttribute to your Action: [OutputCache(Location = OutputCacheLocation.Any, Duration = 300)] public ActionResult Image1() { MemoryStream oStream = new MemoryStream(); using (Bitmap obmp = ImageUtil.RenderImage("called with OutputCacheAttribute", 5, DateTime.Now)) { obmp.Save(oStream, ImageFormat.Jpeg); oStream.Position = 0; return new FileStreamResult(oStream, "image/jpeg"); } } To remove the “OutputCache” module, you use the following in your web.config: <system.webServer> <validation validateIntegratedModeConfiguration="false"/> <modules runAllManagedModulesForAllRequests="true"> <!--<remove name="OutputCache"/>--> </modules>

• Use jQuery and ASP.NET to Build a News Ticker

  Many websites display a news ticker of one sort or another. A news ticker is a user interface element that displays a subset of a list of items, cycling through them one at a time after a set interval. For example, on Cisco's website there is a news ticker that shows the company's latest news items. Each news item is a one sentence link, such as "Desktop Virtualization Gathers Steam," or "Cisco Reports First Quarter Earnings." Clicking a headline whisks you to a page that shows the full story. Cisco's news ticker shows one headline at a time; every few seconds the currently displayed headline fades out and the next one appears. In total, Cisco has five different headlines - the ticker displays each of the five and then starts back from the beginning. This article is the first in a series that explores how to create your own news ticker widget using jQuery and ASP.NET. jQuery is a free, popular, open-source JavaScript library that simplifies many common client-side tasks, like event handling, DOM manipulation, and Ajax. This article kicks off the series and shows how to build a fairly simple news ticker whose contents can be specified statically in HTML markup or created dynamically from server-side code. Future installments will explore adding bells and whistles, such as: stopping the news ticker rotation when the mouse is hovered over it; adding controls to start, stop and pause the headlines; loading new headlines dynamically using Ajax; and packaging the JavaScript used by the ticker into a jQuery plugin.

• A quick hello to the Western Kentucky .NET User Group

  - by Muljadi Budiman

  A few days back, I got a chance to speak at the Western Kentucky .NET User Group meeting in Murray, Kentucky.  The opportunity came up because the original speaker, Jeff Blankenburg, had another obligation and was thus unable to come to this meeting.  I volunteered to deliver his presentation, which is an overview of MIX10 conference. It was a great experience for me; got to drive around and do a little bit of sight-seeing – can’t say I’ve ever been to Kentucky before, so first trip ever there.  I got to meet the user group’s current lead, Tom Turner and got to chat and discuss about all kinds of stuff with the other members.  Cheers to Matt Gawarecki and Brandon Sharp! The presentation itself mostly covers new features in Visual Studio 2010, which was recently released on April 12 – got to demonstrate Historical Debugging in IntelliTrace, Parallel Stacks, View Call Hierarchy and show some Extensions.  We also covered some of the new functionalities in Silverlight 4 (using webcams, drag & drop support among others) and I got to show off Scott Guthrie’s Windows Phone 7 Twitter app.  Altogether, it was quite a bit to cover in 70 minutes or so, but I think everyone enjoyed it. Jeff provided me with the presentation slides (which I modify a bit) and demo applications; so I’m putting it up here for those that may be interested in downloading them.  Please keep in mind that all the demos were made with VS2010 RC, so there may be slight tweaks to get it to work on the RTM version.

• Secure Coding Practices in .NET

  - by SoftwareSecurity

  Thanks to everyone who helped pack the room at the Fox Valley Day of .NET.   This presentation was designed to help developers understand why secure coding is important, what areas to focus on and additional resources.  You can find the slides here. Remember to understand what you are really trying to protect within your application.  This needs to be a conversation between the application owner, developer and architect.  Understand what data (or Asset) needs to be protected.  This could be passwords, credit cards, Social Security Numbers.   This also may be business specific information like business confidential data etc.  Performing a Risk and Privacy Assessment & Threat Model on your applications even in a small way can help you organize this process. These are the areas to pay attention to when coding: Authentication & Authorization Logging & Auditing Event Handling Session and State Management Encryption Links requested Slides Books The Security Development Lifecycle: SDL: A Process for Developing Demonstrably More Secure Software Threat Modeling Writing Secure Code The Web Application Hackers Handbook  Secure Programming with Static Analysis   Other Resources: OWASP OWASP Top 10 OWASP WebScarab OWASP WebGoat Internet Storm Center Web Application Security Consortium Events: OWASP AppSec 2011 in Minneapolis

• New Feature! Automatic Categories for Geekswithblogs.net

  - by Jeff Julian

  One of the features we have been working on is a way to categorize posts without the need of all our bloggers getting on the same page with what categories we have and making them select the categories.  Johnny Kauffman, one of our team members at AJI Software, developed what we call the Sherlock Project over the past few months.  Sherlock is a category suggestion engine based on the content within the posts.  Now, after a post is published, Sherlock will investigate the content and come up with the suggested categories that content fits in.  This will now allow you to go to the specific topics you are interested in and see all the related posts. This is just the beginning, so many more opportunities will arise now that we have our content organized.  One of the first features I will be adding is RSS feeds for each category and sub category.  If you are into ALM, we will have a feed for that! I hope you enjoy these and the engine will continue to get better as we start testing the data.  I hope you are as excited about this as I am :D.  Technorati Tags: Geekswithblogs.net,Categories,Sherlock

• Need theoretical help, how to comprehend an if-else dependency net

  - by macbie

  I am going to face a following issue: I'm writing a program that manages some properties, some of them are general and some are specific. Each property is a pair of key and value, and for example: if it is given a general property and other specific property with exactly the same key and value has been existed before then the general property will swap the specific one in the register. If there are two the same general properties - both will remain in the register. And so on; it is like a net of dependencies. In my case I can handle with it intuitively and foresee all cases, but only because the system is not too vast. What if it would? I have met such problems a few times in many different programs and languages (i.e working with C semaphores) and my question is: How to approach this kind of problem? Is this connected with finite state machine, graph theory or something similar? How to be sure that I have considered the whole system and each possible case? Could you recommend some resources (books, sites) to learn from?

• How to adopt scrum agile methodology for a small .Net team

  - by Thabo

  I am working on a small product based company developing .Net applications. There is a small team with 5-6 developers. I am a person responsible for planning everything. But my primary role is Software developer. Now our current project is very unstable because of poor organization. Today my boss called me and told to submit a report about required resources, appropriate methodology, required man power and their salary scales to make the current project success. I know I don’t have enough organization skills and I need to go deep in my programming skills. So I need to focus only in the development. So I can’t manage the project anymore. Now I am searching some other ways to make ongoing development success. My questions are What is the suitable agile methodology to my team? Is Scrum is suitable for above mentioned scenario? If we adopt Scrum, what we have to do next? (I think hiring new one to manage the project is more suitable. So we have to get Scrum master and some other developers.) Are there any resources (books, Blogs and etc) to get some tips and advices to solve this problem? If Scrum is not a suitable methodology for our scenario, what else can be more suitable methodology to adopt? Can anyone give a good solution for my problem?

• ASP.NET MVC 3 (C#) Software Architecture

  - by ryanzec

  I am starting on a relatively large and ambitious ASP.NET MVC 3 project and just thinking about the best way to organize my code. The project is basically going to be a general management system that will be capable of supporting any type management system whether it be a blogging system, cms, reservation system, wikis, forums, project management system, etc…, each of them being just a separate 'module'. You can read more about it on my blog posted here : http://www.ryanzec.com/index.php/blog/details/8 (forgive me, the style of the site kinda sucks). For those who don't want to read the long blog post the basic idea is that the core system itself is nothing more than a users system with an admin interface to manage the users system. Then you just add on module as you need them and the module I will be creating is a simple blog post to test it out before I move on to the big module which is a project management system. Now I am just trying to think of the best way to structure this so that it is easy for users to add in there own modules but easy for me to update to core system without worrying about the user modifying the core code. I think the ideal way would be to have a number of core projects that user is specifically told not to modify otherwise the system may become unstable and future updates would not work. When the user wants to add in there own modules, they would just add in a new project (or multiple projects). The thing is I am not sure that it is even possible to use multiple projects all with their own controllers, razor view template, css, javascript, etc... in one web application. Ideally each module would have some of it own razor view templates, css, javascript, image files and also need access to some of the core razor view templates, css, javascript, image files which would is in a separate project. It is possible to have 1 web application run off of controllers, razor view templates, css, javascript, image files that are store in multiple projects? Is there a better was to structure this to allow the user to easily add in module with having to modify the core code?

• .NET vs Windows 8: Rematch!

  - by Simon Cooper

  So, although you will be able to use your existing .NET skills to develop Metro apps, it turns out Microsoft are limiting Visual Studio 2011 Express to Metro-only. From the Express website: Visual Studio 11 Express for Windows 8 provides tools for Metro style app development. To create desktop apps, you need to use Visual Studio 11 Professional, or higher. Oh dear. To develop any sort of non-Metro application, you will need to pay for at least VS Professional. I suspect Microsoft (or at least, certain groups within Microsoft) have a very explicit strategy in mind. By making VS Express Metro-only, developers who don't want to pay for Professional will be forced to make their simple one-shot or open-source application in Metro. This increases the number of applications available for Windows 8 and Windows mobile devices, which in turn make those platforms more attractive for consumers. When you use the free VS 11 Express, instead of paying Microsoft, you provide them a service by making applications for Metro, which in turn makes Microsoft's mobile offering more attractive to consumers, increasing their market share. Of course, it remains to be seen if developers forced to jump onto the Metro bandwagon will simply jump ship to Android or iOS instead. At least, that's what I think is going on. With Microsoft, who really knows?

• Structure of a .NET Assembly

  - by Om Talsania

  Assembly is the smallest unit of deployment in .NET Framework.When you compile your C# code, it will get converted into a managed module. A managed module is a standard EXE or DLL. This managed module will have the IL (Microsoft Intermediate Language) code and the metadata. Apart from this it will also have header information.The following table describes parts of a managed module.PartDescriptionPE HeaderPE32 Header for 32-bit PE32+ Header for 64-bit This is a standard Windows PE header which indicates the type of the file, i.e. whether it is an EXE or a DLL. It also contains the timestamp of the file creation date and time. It also contains some other fields which might be needed for an unmanaged PE (Portable Executable), but not important for a managed one. For managed PE, the next header i.e. CLR header is more importantCLR HeaderContains the version of the CLR required, some flags, token of the entry point method (Main), size and location of the metadata, resources, strong name, etc.MetadataThere can be many metadata tables. They can be categorized into 2 major categories.1. Tables that describe the types and members defined in your code2. Tables that describe the types and members referenced by your codeIL CodeMSIL representation of the C# code. At runtime, the CLR converts it into native instructions

• .NET XPath Returns No Results

  - by Stacy Vicknair

  When using XPath in .NET one of the gotchas to be aware of is that all namespaces must be named, otherwise you’ll end up with no results. Default namespaces that are specified with xmlns alone still need to be recognized in the XPath query! Say I had a bit of XML like what is returned from the QueryService web service in Sharepoint: 1: <?xml version="1.0" encoding="UTF-8"?> 2: <ResponsePacket xmlns="urn:Microsoft.Search.Response"> 3: <Response> 4: <Range> 5: ... 6: <Results> 7: <Document xmlns="urn:Microsoft.Search.Response.Document" relevance="849"> 8: ...   When consuming and navigating this response with XPath it is necessary to name all namespaces. Then those named namespaces must be used in reference to the individual element being requested (i.e. doc:Document). In VB: 1: Dim xdoc = new XPathDocument(reader) 2: Dim nav = xdoc.CreateNavigator() 3: Dim nsMgr = new XmlNamespaceManager(nav.NameTable) 4: nsMgr.AddNamespace("resp", "urn:Microsoft.Search.Response") 5: nsMgr.AddNamespace("doc", "urn:Microsoft.Search.Response.Document") 6:  7: Dim results = nav.Select("//doc:Document", nsMgr)   In C#: 1: var xdoc = new XPathDocument(reader); 2: var nav = xdoc.CreateNavigator(); 3: var nsMgr = new XmlNamespaceManager(nav.NameTable); 4:  5: nsMgr.AddNamespace("resp", "urn:Microsoft.Search.Response"); 6: nsMgr.AddNamespace("doc", "urn:Microsoft.Search.Response.Document"); 7:  8: var results = nav.Select("//doc:Document", nsMgr);

• Simplifying data search using .NET

  - by Peter

  An example on the asp.net site has an example of using Linq to create a search feature on a Music album site using MVC. The code looks like this - public ActionResult Index(string movieGenre, string searchString) { var GenreLst = new List<string>(); var GenreQry = from d in db.Movies orderby d.Genre select d.Genre; GenreLst.AddRange(GenreQry.Distinct()); ViewBag.movieGenre = new SelectList(GenreLst); var movies = from m in db.Movies select m; if (!String.IsNullOrEmpty(searchString)) { movies = movies.Where(s => s.Title.Contains(searchString)); } if (!string.IsNullOrEmpty(movieGenre)) { movies = movies.Where(x => x.Genre == movieGenre); } return View(movies); } I have seen similar examples in other tutorials and I have tried them in a real-world business app that I develop/maintain. In practice this pattern doesn't seem to scale well because as the search criteria expands I keep adding more and more conditions which looks and feels unpleasant/repetitive. How can I refactor this pattern? One idea I have is to create a column in every table that is "searchable" which could be a computed column that concatenates all the data from the different columns (SQL Server 2008). So instead of having movie genre and title it would be something like. if (!String.IsNullOrEmpty(searchString)) { movies = movies.Where(s => s.SearchColumn.Contains(searchString)); } What are the performance/design/architecture implications of doing this? I have also tried using procedures that use dynamic queries but then I have just moved the ugliness to the database. E.g. CREATE PROCEDURE [dbo].[search_music] @title as varchar(50), @genre as varchar(50) AS -- set the variables to null if they are empty IF @title = '' SET @title = null IF @genre = '' SET @genre = null SELECT m.* FROM view_Music as m WHERE (title = @title OR @title IS NULL) AND (genre LIKE '%' + @genre + '%' OR @genre IS NULL) ORDER BY Id desc OPTION (RECOMPILE) Any suggestions? Tips?

• Localization of Database Strings in .Net

  - by Aligned

  I have several database tables that have a description column that I need to display in the UI. .Net has .resx files that will help with the translation of the strings, when the Thread.CurrentCulture.UICulture is set, but I needed a custom approach for the strings that are stored in the database and not in the .resx files. Here’s my approach: 1. Create a resource file for each database table and put them in the /Resources/Database/ directory. 2. Create a method in LocalizationHelpers (GetLocalizedString) that will get the string from the table for English (which should be cached to avoid unneeded service/database calls) or the resx when not English. 3. All database tables need to have a ResxKey field that matches the key in the resx file. 4. By convention the resx file will have the same name as the database table, and the key the same as the database ResxKey.   - if there are multiple columns that need translation, then one ResxKey will be used and Name or Description appended. Here’s the method I’m using to pull the string: public static string GetLocalizedString(string resourceName, string resourceKey) { if (executingAssembly == null) { executingAssembly = Assembly.GetExecutingAssembly(); } ResourceManager manager = new ResourceManager(resourceName, executingAssembly); return manager.GetString(resourceKey); }
