• MVC 2 Presentation &ndash; Final Demo

  - by Steve Michelotti

  In my presentation this past weekend at NoVa Code Camp, a member of the audience caught my final demo on video. In this demo, I combine multiple new features from MVC 2 to show how to build apps quickly with MVC 2. These features include: Template Helpers / Editor Templates Server-side/Client-side Validation Model Metadata for View Model HTML Encoding Syntax Dependency Injection Abstract Controllers Custom T4 Templates Custom MVC Visual Studio 2010 Code Snippets The projector screen is a little difficult to see during parts of the video – a video of the direct screencast can be seen here: MVC 2 in 2 Minutes.   Direct link to YouTube video here.

• Syntax Recognition for XML-Based Languages in Oracle JDeveloper

  - by Ramkumar Menon

    @Thanks Jeffrey Stephenson If you are looking at using any one of the new XML Based languages, lets say a docbook xml, or xproc, or what not, you can make use of JDeveloper's syntax highlighting and completion insight feature to ease out those extra keystrokes. All you need is a URL/local copy of the XML Schema for the language. Once you have, you can register it via Tools --> Preferences --> XML Schemas.   Remember to provide a new extension name [Using a default .xml extension did not work for me.] I provided my own extension .dbk for my docbook files. Once you save these settings, you can create new files that conform to the schema, and you get validation/completion insight/prompting for free.

• Can someone explain ORA-29861 error in plain english and its possible cause?

  - by hko19

  I have an application implemented in Grails framework using underlying Hibernate. After it runs for a while, I got an Oracle DB error and resolved it by rebuilding the offending index. I wonder if anyone can propose the possible cause(s) and ways to prevent it from happening. Caused by: org.springframework.jdbc.UncategorizedSQLException: Hibernate operation: Could not execute JDBC batch update; uncategorized SQLException for SQL [update RSS_ITEM set guid=?, pubdate=?, link=?, rss_source_id=?, title=?, description=?, rating_raw=?, rating_tuned=?, date_created=?, date_locked=? where RSS_ITEM_ID=?]; SQL state [99999]; error code [29861]; ORA-29861: domain index is marked LOADING/FAILED/UNUSABLE ; nested exception is java.sql.BatchUpdateException: ORA-29861: domain index is marked LOADING/FAILED/UNUSABLE

• Speaking at Tech-Ed Europe Next Week

  - by Stephen Walther

  I’m going to Berlin! Next week, I’m giving talks at Tech-Ed Europe on two of my favorite topics: What's New in Microsoft ASP.NET Model-View-Controller ASP.NET Model-View-Controller (MVC) 2 introduces new features to make you more productive when building an ASP.NET MVC application. Templated helpers allow automatically associatiating edit and display elements with data types. Areas provide a means of dividing a large Web application into multiple projects. Data annotations allow attaching metadata attributes on a model to control validation. Microsoft ASP.NET AJAX: Taking AJAX to the Next Level Hear how ASP.NET AJAX 4.0 makes building pure client-side AJAX Web applications even easier, and watch us build an entire data-driven ASP.NET AJAX application from start to finish by taking advantage of only JavaScript, HTML pages, and Windows Communication Foundation (WCF) services. Also learn about new ASP.NET AJAX features including the DataView control, declarative templates, live client-side data binding, WCF, and REST integration.   The conference has sold out, but you can register for the wait list: http://www.microsoft.com/europe/TechEd/

• ASP.NET Web API - Screencast series Part 4: Paging and Querying

  - by Jon Galloway

  We're continuing a six part series on ASP.NET Web API that accompanies the getting started screencast series. 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. In Part 1 we looked at what ASP.NET Web API is, why you'd care, did the File / New Project thing, and did some basic HTTP testing using browser F12 developer tools. In Part 2 we started to build up a sample that returns data from a repository in JSON format via GET methods. In Part 3, we modified data on the server using DELETE and POST methods. In Part 4, we'll extend on our simple querying methods form Part 2, adding in support for paging and querying. This part shows two approaches to querying data (paging really just being a specific querying case) - you can do it yourself using parameters passed in via querystring (as well as headers, other route parameters, cookies, etc.). You're welcome to do that if you'd like. What I think is more interesting here is that Web API actions that return IQueryable automatically support OData query syntax, making it really easy to support some common query use cases like paging and filtering. A few important things to note: This is just support for OData query syntax - you're not getting back data in OData format. The screencast demonstrates this by showing the GET methods are continuing to return the same JSON they did previously. So you don't have to "buy in" to the whole OData thing, you're just able to use the query syntax if you'd like. This isn't full OData query support - full OData query syntax includes a lot of operations and features - but it is a pretty good subset: filter, orderby, skip, and top. All you have to do to enable this OData query syntax is return an IQueryable rather than an IEnumerable. Often, that could be as simple as using the AsQueryable() extension method on your IEnumerable. Query composition support lets you layer queries intelligently. If, for instance, you had an action that showed products by category using a query in your repository, you could also support paging on top of that. The result is an expression tree that's evaluated on-demand and includes both the Web API query and the underlying query. So with all those bullet points and big words, you'd think this would be hard to hook up. Nope, all I did was change the return type from IEnumerable<Comment> to IQueryable<Comment> and convert the Get() method's IEnumerable result using the .AsQueryable() extension method. public IQueryable<Comment> GetComments() { return repository.Get().AsQueryable(); } You still need to build up the query to provide the $top and $skip on the client, but you'd need to do that regardless. Here's how that looks: $(function () { //--------------------------------------------------------- // Using Queryable to page //--------------------------------------------------------- $("#getCommentsQueryable").click(function () { viewModel.comments([]); var pageSize = $('#pageSize').val(); var pageIndex = $('#pageIndex').val(); var url = "/api/comments?$top=" + pageSize + '&$skip=' + (pageIndex * pageSize); $.getJSON(url, function (data) { // Update the Knockout model (and thus the UI) with the comments received back // from the Web API call. viewModel.comments(data); }); return false; }); }); And the neat thing is that - without any modification to our server-side code - we can modify the above jQuery call to request the comments be sorted by author: $(function () { //--------------------------------------------------------- // Using Queryable to page //--------------------------------------------------------- $("#getCommentsQueryable").click(function () { viewModel.comments([]); var pageSize = $('#pageSize').val(); var pageIndex = $('#pageIndex').val(); var url = "/api/comments?$top=" + pageSize + '&$skip=' + (pageIndex * pageSize) + '&$orderby=Author'; $.getJSON(url, function (data) { // Update the Knockout model (and thus the UI) with the comments received back // from the Web API call. viewModel.comments(data); }); return false; }); }); So if you want to make use of OData query syntax, you can. If you don't like it, you're free to hook up your filtering and paging however you think is best. Neat. In Part 5, we'll add on support for Data Annotation based validation using an Action Filter.

• More on Visual Studio 11 from Scott Guthrie

  - by TATWORTH

  At http://weblogs.asp.net/scottgu/archive/2011/10/30/web-forms-model-binding-part-3-updating-and-validation-asp-net-4-5-series.aspx, Scott Guthrie talks about data binding is ASP.NET 4.5.There is a key statement "Because our GetProducts() method is returning an IQueryable<Product>, users can easily page and sort through the data within our GridView.  Only the 10 rows that are visible on any given page are returned from the database."Consider paging through a large dataset, this is going to give high performance with very little code as the database to IIS server traffic will be reduced.Can't code withoutThe best C# & VB.NET refactoring plugin for Visual Studio

• How do you decide site availability requirements?

  - by Nathan Long

  I work on a web application to file a specific kind of county taxes. Our company wants our state to mandate that counties must accept electronic filings (as opposed to paper) from any system that meets some sensible requirements for uptime, security, data validation, etc. (Yes, this would help us as a business, but it would also force county governments to be more efficient.) We're creating a draft of those requirements to be reviewed and tweaked with the state. One of the sections is "availability." We want to specify something reasonably high, but not so high that any unexpected problem will get us (or a competitor) penalized. How do we decide what's reasonable for availability requirements?

• Best way to throw exception and avoid code duplication

  - by JF Dion

  I am currently writing code and want to make sure all the params that get passed to a function/method are valid. Since I am writing in PHP I don't have access to all the facilities of other languages like C, C++ or Java to check for parameters values and types public function inscriptionExists($sectionId, $userId) // PHP vs. public boolean inscriptionExists(int sectionId, int userId) // Java So I have to rely on exceptions if I want to make sure that my params are both integers. Since I have a lot of places where I need to check for param validity, what would be the best way to create a validation/exception machine and avoid code duplication? I was thinking on a static factory (since I don't want to pass it to all of my classes) with a signature like: public static function factory ($value, $valueType, $exceptionType = 'InvalidArgumentException'); Which would then call the right sub process to validate based on the type. Am I on the right way, or am I going completely off the road and overthinking my problem?

• Reflection: Is using reflection still "bad" or "slow"? What has changed with reflection since 2002?

  - by blesh

  I've noticed when dealing with Expressions or Expression Trees I'm using reflection a lot to set and get values in properties and what have you. It has occurred to me that the use of reflection seems to be getting more and more common. Things like DataAnotations for validation, Attribute heavy ORMs, etc. Have me wondering: What has changed since the days years and years ago when I used to be told to avoid reflection if at all possible? So what, if anything has changed? Is it just the speed of the machines? Have there been changes to the framework to speed up reflection? Or has nothing really changed? Is it still "bad" or "slow" to use reflection? EDIT: To clarify my question a little.

• ASSIMP in my program is much slower to import than ASSIMP view program

  - by Marco

  The problem is really simple: if I try to load with the function aiImportFileExWithProperties a big model in my software (around 200.000 vertices), it takes more than one minute. If I try to load the very same model with ASSIMP view, it takes 2 seconds. For this comparison, both my software and Assimp view are using the dll version of the library at 64 bit, compiled by myself (Assimp64.dll). This is the relevant piece of code in my software // default pp steps unsigned int ppsteps = aiProcess_CalcTangentSpace | // calculate tangents and bitangents if possible aiProcess_JoinIdenticalVertices | // join identical vertices/ optimize indexing aiProcess_ValidateDataStructure | // perform a full validation of the loader's output aiProcess_ImproveCacheLocality | // improve the cache locality of the output vertices aiProcess_RemoveRedundantMaterials | // remove redundant materials aiProcess_FindDegenerates | // remove degenerated polygons from the import aiProcess_FindInvalidData | // detect invalid model data, such as invalid normal vectors aiProcess_GenUVCoords | // convert spherical, cylindrical, box and planar mapping to proper UVs aiProcess_TransformUVCoords | // preprocess UV transformations (scaling, translation ...) aiProcess_FindInstances | // search for instanced meshes and remove them by references to one master aiProcess_LimitBoneWeights | // limit bone weights to 4 per vertex aiProcess_OptimizeMeshes | // join small meshes, if possible; aiProcess_SplitByBoneCount | // split meshes with too many bones. Necessary for our (limited) hardware skinning shader 0; cout << "Loading " << pFile << "... "; aiPropertyStore* props = aiCreatePropertyStore(); aiSetImportPropertyInteger(props,AI_CONFIG_IMPORT_TER_MAKE_UVS,1); aiSetImportPropertyFloat(props,AI_CONFIG_PP_GSN_MAX_SMOOTHING_ANGLE,80.f); aiSetImportPropertyInteger(props,AI_CONFIG_PP_SBP_REMOVE, aiPrimitiveType_LINE | aiPrimitiveType_POINT); aiSetImportPropertyInteger(props,AI_CONFIG_GLOB_MEASURE_TIME,1); //aiSetImportPropertyInteger(props,AI_CONFIG_PP_PTV_KEEP_HIERARCHY,1); // Call ASSIMPs C-API to load the file scene = (aiScene*)aiImportFileExWithProperties(pFile.c_str(), ppsteps | /* default pp steps */ aiProcess_GenSmoothNormals | // generate smooth normal vectors if not existing aiProcess_SplitLargeMeshes | // split large, unrenderable meshes into submeshes aiProcess_Triangulate | // triangulate polygons with more than 3 edges //aiProcess_ConvertToLeftHanded | // convert everything to D3D left handed space aiProcess_SortByPType | // make 'clean' meshes which consist of a single typ of primitives 0, NULL, props); aiReleasePropertyStore(props); if(!scene){ cout << aiGetErrorString() << endl; return 0; } this is the relevant piece of code in assimp view code // default pp steps unsigned int ppsteps = aiProcess_CalcTangentSpace | // calculate tangents and bitangents if possible aiProcess_JoinIdenticalVertices | // join identical vertices/ optimize indexing aiProcess_ValidateDataStructure | // perform a full validation of the loader's output aiProcess_ImproveCacheLocality | // improve the cache locality of the output vertices aiProcess_RemoveRedundantMaterials | // remove redundant materials aiProcess_FindDegenerates | // remove degenerated polygons from the import aiProcess_FindInvalidData | // detect invalid model data, such as invalid normal vectors aiProcess_GenUVCoords | // convert spherical, cylindrical, box and planar mapping to proper UVs aiProcess_TransformUVCoords | // preprocess UV transformations (scaling, translation ...) aiProcess_FindInstances | // search for instanced meshes and remove them by references to one master aiProcess_LimitBoneWeights | // limit bone weights to 4 per vertex aiProcess_OptimizeMeshes | // join small meshes, if possible; aiProcess_SplitByBoneCount | // split meshes with too many bones.

What could be the reason for such a difference in performance? The two software are using the same dll Assimp64.dll (compiled in my computer with vc++ 2010 express) and the same function aiImportFileExWithProperties to load the model, so I assume that the actual code employed is the same. How is it possible that the function aiImportFileExWithProperties is 100 times slower when called by my sotware than when called by assimp view? What am I missing? I am not good with dll, dynamic and static libraries so I might be missing something obvious. ------------------------------ UPDATE I found out the reason why the code is going slower. Basically I was running my software with "Start debugging" in VC++ 2010 Express. If I run the code outside VC++ 2010 I get same performance of assimp view. However now I have a new question. Why does the dll perform slower in VC++ debugging? I compiled it in release mode without debugging information. Is there any way to have the dll go fast in debugmode i.e. not debugging the dll? Because I am interested in debugging only my own code, not the dll that I assume is already working fine. I do not want to wait 2 minutes every time I want to load my software to debug. Does this request make sense?

• How to specify a SEO friendly url like twitter www.twitter.com/<name> using YII framework

  - by hip10

  Hi, I am currently using the Yii framework, and I would like to know if anyone has any clue on how to setup a SEO friendly url like www.twitter.com/ automatically in Yii? I know how to do so this manually in the config/main.php but I would like to be able to dynamically generate it. I have been able to do it in Grails as well. In Yii, what I know of is that you need to have another parameter like www.twitter.com/l/, but I do not want that parameter, anyone can share? Thanks.

• When to mark a user story as done in scrum?

  - by Saeed Neamati

  There is a notion in scrum that emphasizes delivery of workable units at the end of each sprint. Each workable unit also maps directly of indirectly to a user story and when in new sprint PO introduces new PBI (new user stories), this means that practically team can't always go back to previous user stories to do the rest of the job, which in turn means that when you implement a user story, you should do it as complete as it's known to the team in that time, and you shouldn't forget anything (something like "I'm sorry, I've forgotten to implement validation for that input control" or "I didn't know that cross-browser check is part of the user story"). At the other hand, test, backward compatibility, acceptance criteria, deployment and more and more concepts come after each user story. So, when can team members know that the user story is done completely, not just for demo, and start a new one?

• Fix for EF4 Profiler Issue Coming in next Cumulative Update

  - by Ajarn Mark Caldwell

  Hey!  What do you know?  Microsoft Connect really works! I was very happy this morning to open my email and find a notice from Umachandar on the SQL Programmability Team that they have created a fix for the Odd Profiler Results with EF4 issue that I wrote about last June.  Not only did I blog about it, but I logged an item to Connect with repro steps and sample code.  And now, they have announced that they have a fix for this problem and that it will be included in the next Cumulative Update for SQL Server 2008 R2. For those of you not running 2008 R2, or who prefer to wait for full Service Packs rather than install the latest Cumulative Updates, I also wrote about a workaround for the issue, as long as you do not require the Multiple Active Result Sets feature to be enabled. It is easy with Microsoft to get the feeling that you’re just shouting in the wind, and it is nice to get validation once in a while that they really are listening.

• Visual Studio Macro – Identifier to String Literal

  - by João Angelo

  When implementing public methods with parameters it’s important to write boiler-plate code to do argument validation and throw exceptions when needed, ArgumentException and ArgumentNullException being the most recurrent. Another thing that is important is to correctly specify the parameter causing the exception through the proper exception constructor. In order to take advantage of IntelliSense completion in these scenarios I use a Visual Studio macro binded to a keyboard shortcut that converts the identifier at the cursor position to a string literal. And here’s the macro: Sub ConvertIdentifierToStringLiteral() Dim targetWord As String Dim document As EnvDTE.TextDocument document = CType(DTE.ActiveDocument.Object, EnvDTE.TextDocument) If document.Selection.Text.Length > 0 Then targetWord = document.Selection.Text document.Selection.ReplacePattern(targetWord, """" + targetWord + """") Else Dim cursorPoint As EnvDTE.TextPoint cursorPoint = document.Selection.ActivePoint() Dim editPointLeft As EnvDTE.EditPoint Dim editPointRight As EnvDTE.EditPoint editPointLeft = cursorPoint.CreateEditPoint() editPointLeft.WordLeft(1) editPointRight = editPointLeft.CreateEditPoint() editPointRight.WordRight(1) targetWord = editPointLeft.GetText(editPointRight) editPointLeft.ReplaceText(editPointRight, """" + targetWord + """", 0) End If End Sub

• Is JAX-RS suitable as a MVC framework?

  - by deamon

  JAX-RS has some MVC support, but I wonder if JAX-RS is really a good choice to build web application for human use. If a user enters wrong or incomplete information in a form, it should be displayed again like with Grails or Wicket. Is there a comfortable way to do this with JAX-RS? As far as I know the URI mapping doesn't work correctly, if not all required parameters are given or there are type conversion problems (with Date for example). Is that correct? Is there support for internationalized templates?

• How to explain to non-technical person why the task will take much longer then they think?

  - by Mag20

  Almost every developer has to answer questions from business side like: Why is going to take 2 days to add this simple contact form? When developer estimates this task, they may divide it into steps: make some changes to Database optimize DB changes for speed add front end HTML write server side code add validation add client side javascript use unit tests make sure SEO is setup is working implement email confirmation refactor and optimize the code for speed ... These maybe hard to explain to non-technical person, who basically sees the whole task as just putting together some HTML and creating a table to store the data. To them it could be 2 hours MAX. So is there a better way to explain why the estimate is high to non-developer?
