• Maven + SSDM Build and Runtime Environment Automation

  - by Randy

  Preface: My Company, like most, has several run-time environments and several release versions which themselves are composed of different versions of various jars. For example, let us consider release versions 1.1, 1.2, and 1.3 of Software X, which may be deployed to a developer computer, testing, or production. Software-x-1.1 is itself composed of jarA-0.9.1 and jarB-0.7.5, but software-x-1.3 is composed of jarA-1.7.31 and jarB-0.8.1. Currently we use Spring's PropertyPlaceholderConfigurer to configure run-time variables (such as database credentials), however, properties also change with release versions. We also use Maven 2 POM version 4 to specify which versions of our code need to be used. We place the version numbers of our jars as properties within profiles (dev,test,prod) inside of the parent pom and then reference those version numbers in all project poms. As of right now, we have no way to specify which project versions pertain to a given release other than the most current one. Moreover, we deploy our run-time configurations to the SSDM pickup which then configures and creates the services defined by the built versions of our software. -- Questions: Is there any procedure/tool we can use to build our product by merely providing the run-time environment and version number? IE "build 1.1 dev"? Is there anyway we can store the required jar versions for each release build? We are currently versioning all files, including the parent pom, but merely versioning the parent pom does not record which release version is pertinent to that parent pom. What else can we do to further automate the process of builds? For example, if we could manage run-time configurations within the parent pom that would be a step in the right direction, but that seems like a violation of scope. Any tool outside of our framework is inconceivable at this point, but not in the far future. Summary: How can we automate our build process to the fullest extent without being error prone?

• Webkit browsers rendering CSS different than Mozilla Firefox...Why??

  - by JAG2007

  I'm styling a form that was already marked up (made some markup changes), and I normally work in Firefox to style so I can use firebug and the web developer toolbar. On this project, I noticed that my styles are displaying quite differently for one particular area (several elements) in webkit based browsers Chrome and Safari, than in Firefox (we won't even get into Internet Explorer, although it is siding with the Firefox display). I can't figure out though why the styles are displaying so differently. Normally there is some rule that I'm neglecting that Firefox just takes for granted, and the others need it specified. But here I'm not getting why it's displaying this way. In particular I'm referring to the bottom area of the form where users can enter their contact info, then submit the form. I'll attach screen shots for reference as to the discrepancy. Here's the URL so feel free to check it out on your own. Although be advised that this is a production page (already released) so if you try out the form, you WILL BE added to CURE's contact database. http://www.helpcurenow.org/survey2010 Here's the screen shots: Firefox (the way I intend it to look) Chrome, and then Safari - strange change to submit button As a bonus, if anybody wants to help me with figuring out why on earth IE7 wants to not show the background behind the questions only, and how to fix that I would be much obliged! Thanks very much.

• MVC + Is validation attributes enough?

  - by ebb

  My ViewModel has validation attributes that ensure that it wont be empty etc. - Is that enough or should I let my the code contracts I have made be in the ActionResult too? Example: // CreateCaseViewModel.cs public class CreateCaseViewModel { [Required] public string Topic { get; set; } [Required] public string Message { get; set; } } // CaseController.cs [AuthWhere(AuthorizeRole.Developer)] [HttpPost] public ActionResult Create(CreateCaseViewModel model) { if(!ModelState.IsValid) { // TODO: some cool stuff? } if (string.IsNullOrWhiteSpace(model.Message)) { throw new ArgumentException("Message cannot be null or empty", model.Message); } if (string.IsNullOrWhiteSpace(model.Topic)) { throw new ArgumentException("Topic cannot be null or empty", model.Topic); } var success = false; string message; var userId = new Guid(_membershipService.GetUserByUserName(User.Identity.Name).ProviderUserKey.ToString()); if(userId == Guid.Empty) { throw new ArgumentException("UserId cannot be empty"); } Case createCase = _caseService.CreateCase(model.Topic, model.Message); if(createCase == null) { throw new ArgumentException("Case cannot be null"); } if(_caseService.AddCase(createCase, userId)) { message = ControllerResources.CaseCreateFail; } else { success = true; message = ControllerResources.CaseCreateSuccess; } return Json(new { Success = success, Message = message, Partial = RenderPartialViewToString(ListView, GetCases) }); }

• Which is the best way to encode batch videos on server side?

  - by albanx

  Hello I am making a general question since I am a developer and I have no advance experience on video elaboration. I have to preparare a web application with the purpose to allow video files upload on our company server and then video elaboration by server, on user command. The purpose of the web application is to allow to the user to make some elaboration on video depending on user action launch from the web app: (server has to ) convert video in different format(mp4, flv...) extact keyframes from video and saves them in jpeg format possibility to extract audio from video automatic control of quality audio & video (black frames,silences detection) change scene detection and keyframe extraction ..... This what's my bosses wanted from the web based application (with the server support obviously), and I understand only the first 3 points of this list, the rest for me was arabic.... My question is: Which is the best and fastest server side application for this works, that can support multiple batch video conversions, from command line (comand line for php-soap-socket interaction or something else..)? Is suitable Adobe Media Server for batch video conversion? Which are adobe products that can be used for this purpose? Note: I have experience with Indesign Server scripting programing (sending xml with php and soap call...), and I am looking to something similiar for video elaboration. I will appreciate any answers. THANKS ALL

• Manifesto for Integrated Development Environments

  - by Hugo S Ferreira

  Have you recently take a peek at Coda, or Espresso, or Textmate? Or even Google Chrome's Developer Tools? They are well designed, intuitive, interface rich, and extensible. But Coda, Espresso or Textmate, among several, are text editors, not IDEs. On the other side, VIM and Emacs live in the last century, and Eclipse is an overbloated platform. This is more like an outcry for a decent, common infrastructure for REAL IDEs. But there's some questions attached: (i) what features are needed for such a product and (ii) what products are out there that could fullfil this need, and what are they missing. So here's my draft for a manifesto: Manifesto for Integrated Development Environments: We favor interactivity and productivity over syntax and tools. We favor inline, contextual documentation over man and html files. We favor high-definition, graphic-capable color screens over 80x25 character terminals. We favor the use of advanced input schemas over unintuitive keyboard shortcuts. We favor a common, extensible and customizable infrastructure over unmaintained chaintools. We know the difference between search&replace and refactoring. We know the difference between integrated debugging support over a terminal window. We know the difference between semantic-aware code-completion over dumb textual templates. We favor the usage of standards like (E)BNF.

• What programming technique not done by you, was ahead of its time?

  - by Ferds

  There are developers who understand a technology and produce a solution months or years ahead of its time. I worked with a guy who designed an system using C# beta which would monitor different system components on several servers. He used SQL Server that would pick up these system monitoring components (via reflection) and would instantiate them via an NT Service. The simplicity in this design, was that another developer (me), who understood part of a system, would produce a component that could monitor it, as he had the specialized knowledge of that part of the system. I would derive from the monitor base class (to start, stop and log info), install on the monitoring server GAC and then add an entry to the components table in sql server. Then the main engine would pick up this component and do its magic. I understood parts of it, but couldn't work out by derive from a base class, why add to the GAC etc. This was 6 years ago and it took me months to realize what he achieved. What programming technique not done by you was ahead of its time? EDIT : Techniques that you have seen at work or journals/blogs - I don't mean historically over years.

• Command or tool to display list of connections to a Windows file share

  - by BizTalkMama

  Is there a Windows command or tool that can tell me what users or computers are connected to a Windows fileshare? Here's why I'm looking for this: I've run into issues in the past where our deployment team has deployed BizTalk applications to one of our environments using the wrong bindings, leaving us with two receive locations pointing to the same file share (i.e. both dev and test servers point to dev receive location uri). When this occurs, the two environments in question tend to take turns processing the files received (meaning if I am attempting to debug something in one environment and the other environment has picked the file up, it looks as if my test file has disappeared into thin air). We have several different environments, plus individual developer machines, and I'd rather not have to check each individually to find the culprit. I'm looking for a quick way to detect what locations are connected to the share once I notice my test files vanishing. If I can determine the connections that are invalid, I can go directly to the person responsible for that environment and avoid the time it takes to randomly ask around. Or if the connections appear to be correct, I can go directly to troubleshooting where in the process the message gets lost. Any suggestions?

• PayPal sandbox anomalies

  - by Christian

  When testing some donations on my local machine, I set various key=value pairs to do various things (return to specific thank you page, get POST data from PayPal and not GET data and others) I also built my code around the response from the PayPal sandbox. BUT, when my code goes to the production server and we switch on live payments and test with real accounts and money, a few strange things happen; We get a GET response from PayPal - the URL is filled with crap. We get no transaction details. This is the biggie, no name, no txn_id, no dates, nothing. We get a handful of keys etc, its not totally empty and the payment has gone through, but nowhere near the verbosity of the sandbox. Curious about why this might be? It doesn't really make sense to have a sandbox (or dev environment) that is substantially different from the production environment. Or, am I missing something? EDIT: Still no response to my question in the PayPal Developer Forums. I don't even get a donation amount back from PayPal. Is this a setting maybe? EDIT #2: Two of you have suggested to check PDT and Auto-Return. The data analytics guy for the project only 2 hrs ago suggested the same. I have asked the client to confirm this. I can't see a setting for it in the Sandbox so can assume that it is enabled by default?

• Is there a definitive reference document for Ruby syntax?

  - by JSW

  I'm searching for a definitive document on Ruby syntax. I know about the definitive documents for the core API and standard library, but what about the syntax itself? For instance, such a document should cover: reserved words, string literals syntax, naming rules for variables/classes/modules, all the conditional statements and their permutations, and so forth. I know there are many books and tutorials, yes, but every one of them is essentially a tutorial, each one having a range of different depth and focus. They will all, by necessity of brevity and narrative flow, omit certain details of the language that the author deems insignificant. For instance, did you know that you can use a case statement without an initial case value, and it will then execute the first true when clause? Any given Ruby book or tutorial may or may not cover that particular lesser-known functionality of the case syntax. It's not discussed in the section in "Programming Ruby" about case statements. But that is just one small example. So far the best documentation I've found is the rubyspec project, which appears to be an attempt to write a complete test suite for the language. That's not bad, but it's a bit hard to use from a practical standpoint as a developer working on my own projects. Am I just missing something or is there really no definitive readable document defining the whole of Ruby syntax?

• Calling a WPF Application and modify exposed properties?

  - by Justin

  I have a WPF Keyboard Application, it is developed in such a way that an application could call it and modify its properties to adapt the Keyboard to do what it needs to. Right now I have a file *.Keys.Set which tells the application (on open) to style itself according to that new style. I know this file could be passed as a command line argument into the application. That would not be a problem. My concern is, is there a way via a managed environment to change the properties of the executable as long as they are exposed properly, an example: 'Creates a new instance of the Keyboard Application Dim e_key as new WpfApplication("C:\egt\components\keyboard.exe") 'Sets the style path e_key.SetStylePath("c:\users\joe\apps\me\default.keys.set") e_key.Refresh() 'Applies the style e_key.HideMenu() 'Hides the menu e_key.ShowDeck("PIN") 'Shows the custom "deck" of keyboard keys the developer 'Created in the style application. ''work with events and response 'Clear the instance from memory e_key.close e_key.dispose e_key = nothing This would allow my application to become easily accessible to other Touch Screen Application Developers, allowing them to use my keyboard and keep the functionality they need. It seems like it might be possible because (name of executable).application shows all the exposed functions, properties, and values. I just have never done this before. Any help would be appreciated, thank you in advance.

• Dynamic script addition should be ordered?

  - by hawkettc

  Hi, I'm adding some <script> tags dynamically to the head element after page load. I understand the scripts are loaded asynchronously, but can I expect them to be parsed in the order they are added? I'm seeing the expected behaviour in Firefox, but not in Safari or Chrome. Looking at the document in Chrome developer tools and Firebug, both show the following - <html> <head> ... <script type="text/javascript" src="A.js"></script> <script type="text/javascript" src="B.js"></script> </head> ... </html> However looking at the resource loading view, chrome seems to parse whichever is returned first from the server, while firebug always loads them in the order the script tags were added, even when B is returned first from the server. Should I expect Chrome/Safari to parse the files in the specified order? Using Chrome 5.0.375.29 beta on OS X 10.6.3

• Windows Forms application C# | Sending Tweet

  - by Andrew Craswell

  I've been able to get my Twitter web app working just fine, but I've recently decided to add Tweeting functionality from a Windows Form, but I'm having no luck sending tweets. No errors are thrown or anything. Mind looking over my code? using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using TweetSharp; namespace TwitterAdvirtiser { public partial class Form1 : Form { private string cKey = "xxx"; private string cSecret = "xxx"; private string oToken = "xxx"; private string aToken = "xxx"; public Form1() { InitializeComponent(); OnStart(); } private void OnStart() { //Authenticate with Twitter TwitterService service = new TwitterService(cKey, cSecret); service.AuthenticateWith(oToken, aToken); service.SendTweet("testing"); } } } It seems like I'm authenticating just fine, I can walk through debug mode and see all my details in the TwitterUser structure, and yet my tweets never show up on my feed. Whats up? By the way, I'm using Visual Studios 2010, and .NET 4.0. I have verified that the oToken and aToken strings have my developer tokens.

• Idiomatic PHP web page creation

  - by GreenMatt

  My PHP experience is rather limited. I've just inherited some stuff that looks odd to me, and I'd like to know if this is a standard way to do things. The page which shows up in the browser location (e.g. www.example.com/example_page) has something like: <? $title = "Page Title"; $meta = "Some metadata"; require("pageheader.inc"); ?> <!-- Content --> Then pageheader.inc has stuff like: <? @$title = ($title) ? $title : ""; @$meta = ($meta) ? $meta : ""; ?> <html> <head> <title><?=$title?></title </head> <!-- and so forth --> Maybe others find this style useful, but it confuses me. I suppose this could be a step toward a rudimentary content management system, but the way it works here I'd think it adds to the processing the server has to do without reducing the load on the web developer enough to make it worth the effort. So, is this a normal way to create pages with PHP? Or should I pull all this in favor of a better approach? Also, I know that "<?" (vs. "<?php" ) is undesirable; I'm just reproducing what is in the code.

• I'm graduating with a Computer Science degree but I don't feel like I know how to program.

  - by Wendy Peters

  I'm graduating with a Computer Science degree but I see websites like Stackoverflow and search engines like Google and don't know where I'd even begin to write something like that. During one summer I worked as a iPhone developer, but I felt like I was mostly gluing together libraries that other people had written with little understanding of what's happening underneath the hood. I'm trying to improve my knowledge by studying algorithms, but it is a long and painful process. I find algorithms difficult and at the rate I am working through my book it will a decade will have passed before I will finish. Given my current situation, I've spent a month looking for work but my skills (C, Python, Objective-C) are not so desirable in the local market, where C#, Java, and web development are much higher in demand. My GPA is ok (3.0) but it's not high enough to apply to the large companies or return for graduate studies and I don't have a good network of friends. Basically I'm graduating with a Computer Science degree but I don't feel like I know how to program. I thought that joining a company and programming full-time would give me a chance to develop my skills and learn from those more experienced than myself, but I'm struggling to find work and am starting to get really frustrated. I am going to cast my net wider and look beyond the city I've grown up in, but what have other people in similar situation tried to do?

• Getting a gestureoverlayview

  - by Codejoy

  I have been using some nice tutorials on drawing graphics on my android. I wanted to also add in the cool gesture demo found here: http://developer.android.com/resources/articles/gestures.html That takes these lines of code: GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); This is fine and dandy yet I realize in my demo i'm trying to build using code from "Playing with Graphics in Android". The demos make sense, everything makes sense but I found out by using: setContentView(new Panel(this)); as is required by the Playing With Graphics tutorials, then the findViewById seems to no longer be valid and returns null. At first I was about to post a stupider question as to why this is happening, a quick test of playing with the setContentView made me realize the cause of findViewById returning null, I just do not know how to remedy this issue. Whats the key I am missing here? I realize that the new Panel is doinking some reference up but I am not sure how to make the connection here. The: R.id.gestures is defined right int he main.xml as: (just like the tutorial) <android.gesture.GestureOverlayView android:id="@+id/gestures" android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1.0" /> So I did confirm the setContentView(new Panel(this)) is causing the issue. So I know the issue is that I have to figure out how to add the android.gesture.GestureOverlayView to the panel class somehow, I am just not sure how to go about this. After fighting with this I generally know what I need to do just now how to do it. I think I need either the equivalent of creating a panel in that main.xml OR figuring out how to build whats in main.xml for the gestures in code. I am close because I did this: GestureOverlayView gestures = new GestureOverlayView(this); which gets me a non null gestures now, unfortunately since I am not telling it to fill Parent anywhere I don't think its really showing up, so I am trying hard to figure out layout pa rams. Am I even on the right track?

• Advantage of WPF app vs Winform for business apps?

  - by Abdu

  I know asp.net and winform development. I am not the type of developer who jumps into a new technology just because it's new. It needs to give me extra benefits like higher productivity. What are the advantages of WPF over Winforms for pure business apps? I am not interested in the extra eye candy, animation, gradients, image display effects and so on which WPF provides. The business apps are for data entry, data reporting and maybe some charts and static display of photos. How will WPF help in these apps? Better richer data binding? WinForm is a mature proven technology and I like the fact I can do everything in Visual Studio vs multiple IDE's for WPF (VS & Blend family). Plus I think WPF doesn't have as rich data binding controls like their Winform counterparts (DataGridView..etc). AFAIK, Microsoft will still support Winforms for many years. Try to convince someone like me to switch.

• Interface Builder vs Cocos 2D - how choice the best for your app.

  - by baDa

  Hello everyone! I was a flash developer for 3 years, and in the last 5 months, i begin the iphone development, i do 2 applications with interface builder for clients, and now i really want to do a little game, is quite simple, one match 3! I made the engine in interface builder, and seens good to me! But after i read some posts, i really want to try it in the cocos2D! So, in 2 days i rewrite all my first engine for cocos2D, very annoying upsidedown coordinates but ok, i really do! But the performance side by side with interface builder version is really scare! Many Many slow downs at the cocos2d side! And the animation seens bugged to me! I really scare! I really don't know what is the best choice for a simple game. And i want some opinions: Using cocos2d when need some physics? When we have many objects at screen? What is the performance boost i have with cocos2D? I have how to share this 2 applications with you guys?! Without your UID?!

• Planning and coping with deadlines in SCRUM

  - by John

  From wikipedia: During each “sprint”, typically a two to four week period (with the length being decided by the team), the team creates a potentially shippable product increment (for example, working and tested software). The set of features that go into a sprint come from the product “backlog,” which is a prioritized set of high level requirements of work to be done. Which backlog items go into the sprint is determined during the sprint planning meeting. During this meeting, the Product Owner informs the team of the items in the product backlog that he or she wants completed. The team then determines how much of this they can commit to complete during the next sprint. During a sprint, no one is allowed to change the sprint backlog, which means that the requirements are frozen for that sprint. After a sprint is completed, the team demonstrates the use of the software. I was reading this and two questions immediately popped into my head: 1)If a sprint is only a couple of weeks, decided in a single meeting, how can you accurately plan what can be achieved? High-level tasks can't be estimated accurately in my experience, and can easily double what seems reasonable. As a developer, I hate being pushed into committing what I can deliver in the next month based on a set of customer requirements, this goes against everything I know about generating reliable estimates rather than having to roughly estimate and then double it! 2)Since the requirements are supposed to be locked and a deliverable product available at the end, what happens when something does take twice as long? What if this feature is only 1/2 done at the end of the sprint? The wiki article goes on to talk about Sprint planning, where things are broken down into much smaller tasks for estimation (<1 day) but this is after the Sprint features are already planned and the release agreed, isn't it? kind of like a salesman promising something without consulting the developers.

• Can I get the IE debugger to break into long-running javascript

  - by Brian Deacon

  I have a page that has a byzantine amount of javascript running. In IE only, and only version 8, I get a long-script warning that I can reliably reproduce. I suspect it is event handlers triggering themselves in an infinite loop. The Developer Tools are limping horribly under the weight of the script running, but I do seem to be able to get the log to tell me what line of script it was executing when I aborted, but it is inevitably some of the deep plumbing of the ExtJS code we use, and I can't tell where it is in my stack of code. A way of seeing the call stack would work, but preferably I'd like to be able to just break into the debugger when I get the long script warning so I can just step through the stack. There is a similar question posted, but the answers given were for a not-the-right-tool, or the not terribly helpful advice to eliminate half my code at a time on a binary hunt for the infinite loop. If my code were simple enough that I could do that, it probably wouldn't have gotten the infinite loop in the first place. If I could reproduce the problem in firebug, I'd probably be a lot happier too.

• How do you use indent in vim for web development?

  - by Somebody still uses you MS-DOS

  I'm starting to use Linux and Vim at work. I'm starting to read vims documentation and creating my own .vimrc file and such. I'm a web developer working with HTML, XML, CSS, JS, Python, PHP, ZPT, DTML and SQL. I would like to have an indent feature like this one: for each language/set, a corresponding indent solution. So, in js, writing function test(){|} would turn in function test(){ | } If php, writing <?php function test(){|}: <?php function test(){ | } <?php> ...and such. Writing a function definition in Python, and then creating a for loop sentece, it would automatically create an indent. I'm starting with autoindent, smartindent, cindent but I'm a little confused about their differences. How do the indent in vim works? Am I supposed to download plugins for each language? Is the behavior I described possible with already existing plugins you're used to or do I have to create it? I keep seeing people using Vim and I'm trying to do this as well since the machine I'm using is too limited, but I'm afraid I won't be able to have a decent auto indenting solution in it. (I have used autoindenting in a little small project in Visual Studio, and really liked their approach. Is there a plugin for that?)

• I'm confused, how do I control cache so my clients can see website edits.

  - by Jared Christensen

  I host about 10 websites for clients. Every so often a client will ask for an update to their website. It may be a simple image change, new PDF or a simple text change. I make the change and then send them a link to the web page with the update. About an hour later I will get an email back from the client telling me they still see the old page. I will then explaining to them how to empty their browsers cache. What I'm trying to figure out is if there is a way I can tell their browser that I made an update to the website and that it should reload the page and update the cache. I thought about trying a meta tag but I read that they are not very reliable. Also I would still like the page to cache I just want to be able to clear it when I make an update. Is this possible? I'm an advanced front end web developer (HTML, CSS, Javascript) and know some PHP. Cache is just one of those things I don't really understand that well.

• OpenGL ES and real world development

  - by Mark

  Hi Guys, I'm trying to learn OpenGL ES quickly (I know, I know, but these are the pressures that have been thrusted upon me) and I have been read around a fair bit, which lots of success at rendering basic models, some basic lighting and 'some' texturing success too. But this is CONSTANTLY the point at which all OpenGL ES tutorials end, they never say more of what a real life app may need. So I have a few questions that Im hoping arent too difficult. How do people get 3d models from their favorite 3d modeling tool into the iPhone/iPad application? I have seen a couple of blog posts where people have written some python scripts for tools like Blender which create .h files that you can use, is this what people seem to do everytime? Or do the "big" tooling suites (3DS, Maya, etc...) have exporting features? Say I have my model in a nice .h file, all the vertexes, texture points, etc.. are lined up, how to I make my model (say of a basic person) walk? Or to be more general, how do you animate "part" of a model (legs only, turn head, etc...)? Do they need to be a massive mash-up of many different tiny models, or can you pre-bake animations these days "into" models (somehow) Truely great 3D games for the iPhone are (im sure) unbelievably complex, but how do people (game dev firms) seem to manage that designer/developer workflow? Surely not all the animations, textures, etc... are done programatically. I hope these are not stupid questions, and in actual fact, my app that Im trying to investigate how to make is really quite simple, just a basic 3D model that I want to be able to pan/tilt around using touch. Has anyone ever done/seen anything like this that I might be able to read up on? Thanks for any help you can give, I appreciate all types of response big or small :) Cheers, Mark

• Entity Filter child without include

  - by Lic

  i'm a C# developer and i have a trouble with Entity Framework 5. I have mapped my database with Entity using the default code generation strategy. In particolar there are three classes: menus, submenus and submenuitems. The relationships about three classes are: one menu - to many submenus one submenu - to many submenuitems. All classes have a boolean attribute called "Active". Now, i want to filter all the Menus with the SubMenus active, and the SubMenus with the SubMenuItems active. To get this i've tried this: var tmp = _model.Menus.Where(m => m.Active) .Select => new { Menu = x, SubMenu = x.SubMenus.Where(sb => sb.Active) .Select(y => new { SubMenu = y, SubMenuItem = y.SubMenuItems.Where(sbi => sbi.Active) }) }) .Select(x => x.Menu).ToList(); But didn't work. Someone can help me? Thank you for your help!

• What pattern is layered architecture in asp.net ?

  - by haansi

  Hi, I am a asp.net developer and don't know much about patterns and architecture. I will very thankful if you can please guide me here. In my web applications I use 4 layers. Web site project (having web forms + code behind cs files, user controls + code behind cs files, master pages + code behind cs files) CustomTypesLayer a class library (having custom types, enumerations, DTOs, constructers, get, set and validations) BusinessLogicLayer a class library (having all business logic, rules and all calls to DAL functions) DataAccessLayer a class library( having just classes communicating to database.) -My user interface just calls BusinessLogicLayer. BusinessLogicLayer do proecessign in it self and for data it calls DataAccessLayer funtions. -Web forms do not calls directly DAL. -CustomTypesLayer is shared by all layers. Please guide me is this approach a pattern ? I though it may be MVC or MVP but pages have there code behind files as well which are confusing me. If it is no patren is it near to some patren ? pleaes guide thanks

• How Best to Replace PL/SQL with C#?

  - by Mike

  Hi, I write a lot of one-off Oracle SQL queries/reports (in Toad), and sometimes they can get complex, involving lots of unions, joins, and subqueries, and/or requiring dynamic SQL, and/or procedural logic. PL/SQL is custom made for handling these situations, but as a language it does not compare to C#, and even if it did, it's tooling does not, and if even that did, forcing yet another language on the team is something to be avoided whenever possible. Experience has shown me that using SQL for the set based processing, coupled with C# for the procedural processing, is a powerful combination indeed, and far more readable, maintainable and enhanceable than PL/SQL. So, we end up with a number of small C# programs which typically would construct a SQL query string piece by piece and/or run several queries and process them as needed. This kind of code could easily be a disaster, but a good developer can make this work out quite well, and end up with very readable code. So, I don't think it's a bad way to code for smaller DB focused projects. My main question is, how best to create and package all these little C# programs that run ad hoc queries and reports against the database? Right now I create little report objects in a DLL, developed and tested with NUnit, but then I continue to use NUnit as the GUI to select and run them. NUnit just happens to provide a nice GUI for this kind of thing, even after testing has been completed. I'm also interested in suggestions for reporting apps generally. I feel like there is a missing piece or product. The perfect tool would allow writing and running C# inside of Toad, or SQL inside of Visual Studio, along with simple reporting facilities. All ideas will be appreciated, but let's make the assumption that PL/SQL is not the solution.
