  • Default Parameter in .NET 4(C#)

    - by Yousef_Jadallah
    During my using for the new release .NET 4, I notice that C# support default (Optional) Parameters, after thousands of complains form C# programmer- especially it was supported by VB.NET- now it's available. Let's create Test function with Optional Parameter   private void TestFunction(string para1, string para2 = "Default") { Response.Write("Parameter one =" + para1 +" , Parameter two="+ para2 ); } Then, if you try to call this method the Intellisense display likes this:   .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; }   Therefore,if you don’t pass the second parameter the value of para2 will be “Default”. With this new future in C#, you can ignore many overload functions event it was acceptable solution!

  • Sponsor the Hottest .NET Community Event in Germany: dotnet Cologne 2011

    - by WeigeltRo
    The “dotnet Cologne” conference organized by the NET usergroups Bonn and Cologne quickly has become the .NET community event in Germany. So when we opened the registration for dotnet Cologne 2011 on Monday, we expected some interest. But we didn’t expect the 200 “early bird” seats to be gone in less than three hours! And the registrations at normal price keep coming in, so it looks like this event will sell out even earlier than last year. In December I wrote about sponsorship opportunities at the dotnet Cologne 2011 – and why it’s a good idea to be a sponsor at this particular conference. If you are interested in becoming a sponsor: We still offer a wide variety of sponsorship packages in different sizes. At our new, larger, event location, we still have space for exhibition booths. Last year’s exhibitors were very happy and had many interesting conversations with the attendees. And this year we planned for longer breaks between sessions, which means event more time for presenting your products. And yes, German developers understand English demos. But maybe a booth is a bit too much for you. With the Bronze package, you can make sure the attendees receive promotional material of your company in their bags – for a fraction of what you’d pay at a commercial conference. Or you could sponsor a couple of licenses of your product for the raffle at the end of the day. If you want to learn more, just send an email to Roland.Weigelt at dotnet-koelnbonn.de and I’ll send you our sponsor information.

  • .NET development on Macs

    - by Jeff
    I posted the “exciting” conclusion of my laptop trade-ins and issues on my personal blog. The links, in chronological order, are posted below. While those posts have all of the details about performance and software used, I wanted to comment on why I like using Macs in the first place. It started in 2006 when Apple released the first Intel-based Mac. As someone with a professional video past, I had been using Macs on and off since college (1995 graduate), so I was never terribly religious about any particular platform. I’m still not, but until recently, it was staggering how crappy PC’s were. They were all plastic, disposable, commodity crap. I could never justify buying a PowerBook because I was a Microsoft stack guy. When Apple went Intel, they removed that barrier. They also didn’t screw around with selling to the low end (though the plastic MacBooks bordered on that), so even the base machines were pretty well equipped. Every Mac I’ve had, I’ve used for three years. Other than that first one, I’ve also sold each one, for quite a bit of money. Things have changed quite a bit, mostly within the last year. I’m actually relieved, because Apple needs competition at the high end. Other manufacturers are finally understanding the importance of industrial design. For me, I’ll stick with Macs for now, because I’m invested in OS X apps like Aperture and the Mac versions of Adobe products. As a Microsoft developer, it doesn’t even matter though… with Parallels, I Cmd-Tab and I’m in Windows. So after three and a half years with a wonderful 17” MBP and upgraded SSD, it was time to get something lighter and smaller (traveling light is critical with a toddler), and I eventually ended up with a 13” MacBook Air, with the i7 and 8 gig upgrades, and I love it. At home I “dock” it to a Thunderbolt Display.

  • ASP.NET: Serializing and deserializing JSON objects

    - by DigiMortal
    ASP.NET offers very easy way to serialize objects to JSON format. Also it is easy to deserialize JSON objects using same library. In this posting I will show you how to serialize and deserialize JSON objects in ASP.NET. All required classes are located in System.Servicemodel.Web assembly. There is namespace called System.Runtime.Serialization.Json for JSON serializer. To serialize object to stream we can use the following code. var serializer = new DataContractJsonSerializer(typeof(MyClass)); serializer.WriteObject(myStream, myObject); To deserialize object from stream we can use the following code. CopyStream() is practically same as my Stream.CopyTo() extension method. var serializer = new DataContractJsonSerializer(typeof(MyClass));   using(var stream = response.GetResponseStream()) using (var ms = new MemoryStream()) {     CopyStream(stream, ms);     results = serializer.ReadObject(ms) as MyClass; } Why I copied data from response stream to memory stream? Point is simple – serializer uses some stream features that are not supported by response stream. Using memory stream we can deserialize object that came from web.

  • .NET Application broken on one PC, unhandleable exception

    - by Bobby
    Hello people. I have a .NET 2.0 application with nothing fancy in it. It worked until yesterday on every PC I installed or copied it to, no matter if 2.0, 3.0, 3.5 or 3.5 SP1 was installed, no matter if it was Win2000, XP or even Win7 (in total 100+ machines). Yesterday I did my normal installation procedure and wanted to start it one time to check if everything is working...and it wasn't. The program crashed hard leaving me with the uninformative "Do you wanna report this error?" dialog. The problem is an exception in the Main(String[] args) routine of my application. The event viewer is showing the following entry: Event Type: ErrorEvent Source: .NET Runtime 2.0 Error Reporting Event Category: None Event ID: 5000 Date: 05/05/2010 Time: 16:09:09 User: N/A Computer: myClientPC Description: EventType clr20r3, P1 apomenu.exe, P2 1.4.90.53, P3 4bdedea4, P4 system.configuration, P5 2.0.0.0, P6 4889de74, P7 1a6, P8 136, P9 ioibmurhynrxkw0zxkyrvfn0boyyufow, P10 NIL. Well...great information. After a lot of searching I finally was able to get further information about this exception (by adding a handler for UnhandledExceptions directly in My.MyApplication.New(), Application.Designer.vb): System.Configuration.ConfigurationErrorsException Configuration system failed to initialize at System.Configuration.ClientConfigurationSystem.EnsureInit(String configKey) at System.Configuration.ClientConfigurationSystem.PrepareClientConfigSystem(String sectionName) at System.Configuration.ClientConfigurationSystem.System.Configuration.Internal.IInternalConfigSystem.GetSection(String sectionName) at System.Configuration.ConfigurationManager.GetSection(String sectionName) at System.Configuration.PrivilegedConfigurationManager.GetSection(String sectionName) at System.Net.Configuration.SettingsSectionInternal.get_Section() at System.Net.Sockets.Socket.InitializeSockets() at System.Net.Sockets.Socket.get_SupportsIPv4() at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.get_HostName() at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.RegisterChannel(Boolean SecureChannel) at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.Run(String[] commandLine) at MyAppNameHere.My.MyApplication.Main(String[] Args) in 17d14f5c-a337-4978-8281-53493378c1071.vb:Line 81. And at this point I'm stuck...I'm out of ideas. I'm not using any kind of configuration system from the framework (no reference to System.Configuration, and there never was a MyAppnameHere.exe.config generated or distributed, nor have I seen this error before). I also found a bug report at Microsoft (Google Cache) about this bug (in another context, though). But as it seems, they won't even look at it. Every help is greatly appreciated! Edit: I'm using Visual Studio 2008 Prof.. Crash happens in Release- and Debug-Build on the client machine. Debugging the application directly on this machine is out of question I fear, 300+ Miles and they only have two computers to work with.

  • ASP.NET 2.0 and 4.0 seem to treat the root url differently in Forms Authentication

    - by Kev
    If have the following web.config: <configuration> <system.web> <authentication mode="Forms"> <forms name="MembershipCookie" loginUrl="Login.aspx" protection="All" timeout="525600" slidingExpiration="true" enableCrossAppRedirects="true" path="/" /> </authentication> <authorization> <deny users="?" /> </authorization> </system.web> <location path="Default.aspx"> <system.web> <authorization> <allow users="*"/> </authorization> </system.web> </location> </configuration> The application is an ASP.NET 2.0 application running on Windows 2008R2/IIS7.5. If the site's application pool is configured to run ASP.NET 2.0 and I browse to http://example.com then Default.aspx is rendered as you'd expect from the rules above. However if the application pool is set to run ASP.NET 4.0 I am redirected to the login page. If I explicitly specify http://example.com/default.aspx then all is good and default.aspx renders. I've tried rewriting / -> /default.aspx (using IIS UrlRewriter 2.0) but the result is still the same, I get kicked to the login page. I've also tried this with an ASP.NET 4.0 application with the same result (which is where the problem initially arose). The reason I tried this with a 2.0 application was to see if there was a change in behaviour, and it seems that / is handled differently in 4.0. So to summarise, using the configuration above the following is observed: ASP.NET Version Url Behaviour ------------------------------------------------------------------------- 2.0 http://example.com Renders Default.aspx 2.0 http://example.com/Default.aspx Renders Default.aspx 4.0 http://example.com Redirects to Login.aspx 4.0 http://example.com/Default.aspx Renders Default.aspx Is this a bug/breaking change or have I missed something glaringly obvious?

  • jQuery Ajax Error Handling – How To Show Custom Error Messages

    - by schnieds
    So you want to make your error feedback nice for your users…Kind of an ironic statement isn’t it? We obviously want to avoid errors if at all possible in our applications, but when errors do occur then we want to provide some nice feedback to our users. The worst thing that can happen is to blow up a huge server exception page when something goes wrong or equally bad is not providing any feedback at all and leaving the user in the dark. Although I do not recommend displaying actual .NET Framework exception messages or stack traces to the user in most instances; they are usually not helpful to the user and can be a security concern....

  • JustMock and Moles – A short overview for TDD alpha geeks

    - by RoyOsherove
    People have been lurking near my house, asking me to write something about Moles and JustMock, so I’ll try to be as objective as possible, taking in the fact that I work at Typemock. If I were NOT working at Typemock I’d write: JustMock JustMock tries to be Typemock at so many levels it’s not even funny. Technically they work the same and the API almost looks like it’s a search and replace work based on the Isolator API (awesome compliment!), but JustMock still has too many growing pains and bugs to be usable. Also, JustMock is missing alot of the legacy abilities such as Non public faking, faking all types and various other things that are really needed in real legacy code. Biggest thing (in terms of isolation integration) is that it does not integrate with other profilers such as coverage, NCover etc.) When JustMock comes out of beta, I feel that it should cost about half as Isolator costs, as it currently provides about half the abilities. Moles Moles is an addon of Pex and was originally only intended to work within the Pex environment. It started as a research project and now it’s a power-tool for VS (so it’s a separate install) Now it’s it’s own little stubbing framework. It’s not really an Isolation framework in the classic sense, because it does not provide any kind of API built in to verify object interactions. You have to use manual flags all on your own to do that. It generates two types of classes per assembly: Manual Stubs(just like you’d hand code them) and Mole classes. Each Mole class is a special API to change and break the behavior that the corresponding type. so MDateTime is how you change behavior for DateTime. In that sense the API is al over the place, and it can become highly unreadable and unmentionable over time in your test. Also, the Moles API isn’t really designed to deal with real Legacy code. It only deals with public types and methods. anything internal or private is ignored and you can’t change its behavior. You also can’t control static constructors. That takes about 95% of legacy scenarios out of the picture if that’s what you’re trying to use it for. Personally, I found it hard to get used to the idea of two parallel APIs for different abilities, and when to choose which. and I know this stuff. I would expect more usability from the API to make it more widely used. I don’t think that Moles in planning to go that route. Publishing it as an Isolation framework is really an afterthought of a tool that was design with a specific task in mind, and generic Isolation isn’t it. it’s only hope is DEQ – a simple code example that shows a simple Isolation API built on the Moles generic engine. Moles can and should be used for very simple cases of detouring functionality such a simple static methods or interfaces and virtual functions (like rhinomock and MOQ do).   Oh, Wait. Ah, good thing I work at Typemock. I won’t write all that. I’ll just write: JustMock and Moles are great tools that enlarge the market space for isolation related technologies, and they prove that the idea of productivity and unit testing can go hand in hand and get people hooked. I look forward to compete with them at this growing market.

  • Editing Routes in ASP.NET MVC

    - by imran_ku07
    Introduction :        Phil Haack's had written two great articles about Editable Routes, Editable Routes or Editable Routes Using App_Code.These Article are great. But if you not need to unit test your Routes and don't care about restart Application Domian during editing your Routes then global.asax file is the fastest and easiest to achieve the same. In this Article I will use Global.asax file instead of Global.asax.cs file for defining Routes and you will also see how this whole process will works.   Description :          You just need to Cut (or Copy) the code inside Global.asax.cs and paste it in Global.asax inside runat server tag.          You can simply do this by cutting the code of Global.asax.cs,          and paste it inside Global.asax,               Easy and quick ,Now you can change Global.asax without compiling the application. How this works :        I think it is worth here to see what is happening here.        Actually, ASP.NET will use Global.asax file to create a class named global_asax within ASP namespace and place all the code in Global.asax inside the class global_asax class which is created at runtime,                namespace ASP               {                    public class global_asax: NerdDinner.MvcApplication                    {                         //Any definitions defined in Global.asax like Application_Start method                                     }               }         Which inherits from class defined in Application tag,      <%@ Application Codebehind="Global.asax.cs" Inherits="NerdDinner.MvcApplication" Language="C#" %>          Actually ASP.NET creates a pool of application objects of this class, which varies from 1 to 100. Every request take one of these application objects to a serve incoming requests. After receiving an application object then it will call application specific events, like Application_Start(for only firstRequest), Application_BeginRequest(for every request), and so on. Therefore if these methods are defined in global_asax class then ASP.NET will call these method from global_asax, if not then it will use base class methods may be defined in Global.asax.cs(the concept known as shadowing or hiding). Summary :        In this article, I showed how easily and quickly you can make your Routes Editable. But also note that any change in global.asax results in Application Domain restart and this technique also makes your Route Unit Test difficult.

  • First time using Java Web Start in Ubuntu - Fatal Launch Exception

  • List of Microsoft training kits (2012)

    - by DigiMortal

  • Fix: WCF - The type provided as the Service attribute value in the ServiceHost directive could not

    - by Ken Cox [MVP]
    I wanted to expose some raw data to users in my current ASP.NET 3.5 web site project. I created a subdirectory called ‘datafeeds’ and added a WCF Data Service. I wired the dataservice up to the Entity Framework class and, on running the ItemDataService.svc file, was greeted with: The type  <> provided as the Service attribute value in the ServiceHost directive could not be found So why couldn’t it find the class? It was right there in the… oops! Instead of putting the ItemDataService.vb...(read more)

  • ASP.NET MVC 3 Hosting :: ASP.NET MVC 3 First Look

    - by mbridge
    MVC 3 View Enhancements MVC 3 introduces two improvements to the MVC view engine: - Ability to select the view engine to use. MVC 3 allows you to select from any of your  installed view engines from Visual Studio by selecting Add > View (including the newly introduced ASP.NET “Razor” engine”): - Support for the next ASP.NET “Razor” syntax. The newly previewed Razor syntax is a concise lightweight syntax. MVC 3 Control Enhancements - Global Filters: ASP.NET MVC 3  allows you to specify that a filter which applies globally to all Controllers within an app by adding it to the GlobalFilters collection.  The RegisterGlobalFilters() method is now included in the default Global.asax class template and so provides a convenient place to do this since is will then be called by the Application_Start() method: void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new HandleLoggingAttribute()); filters.Add(new HandleErrorAttribute()); } void Application_Start() { RegisterGlobalFilters (GlobalFilters.Filters); } - Dynamic ViewModel Property : MVC 3 augments the ViewData API with a new “ViewModel” property on Controller which is of type “dynamic” – and therefore enables you to use the new dynamic language support in C# and VB pass ViewData items using a cleaner syntax than the current dictionary API. Public ActionResult Index() { ViewModel.Message = "Hello World"; return View(); } - New ActionResult Types : MVC 3 includes three new ActionResult types and helper methods: 1. HttpNotFoundResult – indicates that a resource which was requested by the current URL was not found. HttpNotFoundResult will return a 404 HTTP status code to the calling client. 2. PermanentRedirects – The HttpRedirectResult class contains a new Boolean “Permanent” property which is used to indicate that a permanent redirect should be done. Permanent redirects use a HTTP 301 status code.  The Controller class  includes three new methods for performing these permanent redirects: RedirectPermanent(), RedirectToRoutePermanent(), andRedirectToActionPermanent(). All  of these methods will return an instance of the HttpRedirectResult object with the Permanent property set to true. 3. HttpStatusCodeResult – used for setting an explicit response status code and its associated description. MVC 3 AJAX and JavaScript Enhancements MVC 3 ships with built-in JSON binding support which enables action methods to receive JSON-encoded data and then model-bind it to action method parameters. For example a jQuery client-side JavaScript could define a “save” event handler which will be invoked when the save button is clicked on the client. The code in the event handler then constructs a client-side JavaScript “product” object with 3 fields with their values retrieved from HTML input elements. Finally, it uses jQuery’s .ajax() method to POST a JSON based request which contains the product to a /theStore/UpdateProduct URL on the server: $('#save').click(function () { var product = { ProdName: $('#Name').val() Price: $('#Price').val(), } $.ajax({ url: '/theStore/UpdateProduct', type: "POST"; data: JSON.stringify(widget), datatype: "json", contentType: "application/json; charset=utf-8", success: function () { $('#message').html('Saved').fadeIn(), }, error: function () { $('#message').html('Error').fadeIn(), } }); return false; }); MVC will allow you to implement the /theStore/UpdateProduct URL on the server by using an action method as below. The UpdateProduct() action method will accept a strongly-typed Product object for a parameter. MVC 3 can now automatically bind an incoming JSON post value to the .NET Product type on the server without having to write any custom binding. [HttpPost] public ActionResult UpdateProduct(Product product) { // save logic here return null } MVC 3 Model Validation Enhancements MVC 3 builds on the MVC 2 model validation improvements by adding   support for several of the new validation features within the System.ComponentModel.DataAnnotations namespace in .NET 4.0: - Support for the new DataAnnotations metadata attributes like DisplayAttribute. - Support for the improvements made to the ValidationAttribute class which now supports a new IsValid overload that provides more info on  the current validation context, like what object is being validated. - Support for the new IValidatableObject interface which enables you to perform model-level validation and also provide validation error messages which are specific to the state of the overall model. MVC 3 Dependency Injection Enhancements MVC 3 includes better support for applying Dependency Injection (DI) and also integrating with Dependency Injection/IOC containers. Currently MVC 3 Preview 1 has support for DI in the below places: - Controllers (registering & injecting controller factories and injecting controllers) - Views (registering & injecting view engines, also for injecting dependencies into view pages) - Action Filters (locating and  injecting filters) And this is another important blog about Microsoft .NET and technology: - Windows 2008 Blog - SharePoint 2010 Blog - .NET 4 Blog And you can visit here if you're looking for ASP.NET MVC 3 hosting

  • Delegates and Events in C#

    - by hakanbilge
    Events and their underlying mechanism "Delegates" are very powerful tools of a developer and Event Driven Programming is one of the main Programming Paradigms. Its wiki definition is "event-driven programming or event-based programming is a programming paradigm in which the flow of the program is determined by events?i.e., sensor outputs or user actions (mouse clicks, key presses) or messages from other programs or threads." That means, your program can go its own way sequentially and in the case of anything that requires attention is done (when an event fires) by somebody or something, you can response it by using that event's controller method (this mechanism is like interrupt driven programming in embedded systems). There are many real world scenarios for events, for example, ASP.NET uses events to catch a click on a button or in your app, controller has notice of a change in UI by handling events exposed by view (in MVC pattern). Delegates in C# C# delegates correspond to function pointers in  [read more....]

  • JavaScript Intellisense Improvements with VS 2010

    - by ScottGu
    This is the twentieth in a series of blog posts I’m doing on the upcoming VS 2010 and .NET 4 release.  Today’s blog post covers some of the nice improvements coming with JavaScript intellisense with VS 2010 and the free Visual Web Developer 2010 Express.  You’ll find with VS 2010 that JavaScript Intellisense loads much faster for large script files and with large libraries, and that it now provides statement completion support for more advanced scenarios compared to previous versions of Visual Studio. [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Improved JavaScript Intellisense Providing Intellisense for a dynamic language like JavaScript is more involved than doing so with a statically typed language like VB or C#.  Correctly inferring the shape and structure of variables, methods, etc is pretty much impossible without pseudo-executing the actual code itself – since JavaScript as a language is flexible enough to dynamically modify and morph these things at runtime.  VS 2010’s JavaScript code editor now has the smarts to perform this type of pseudo-code execution as you type – which is how its intellisense completion is kept accurate and complete.  Below is a simple walkthrough that shows off how rich and flexible it is with the final release. Scenario 1: Basic Type Inference When you declare a variable in JavaScript you do not have to declare its type.  Instead, the type of the variable is based on the value assigned to it.  Because VS 2010 pseudo-executes the code within the editor, it can dynamically infer the type of a variable, and provide the appropriate code intellisense based on the value assigned to a variable. For example, notice below how VS 2010 provides statement completion for a string (because we assigned a string to the “foo” variable): If we later assign a numeric value to “foo” the statement completion (after this assignment) automatically changes to provide intellisense for a number: Scenario 2: Intellisense When Manipulating Browser Objects It is pretty common with JavaScript to manipulate the DOM of a page, as well as work against browser objects available on the client.  Previous versions of Visual Studio would provide JavaScript statement completion against the standard browser objects – but didn’t provide much help with more advanced scenarios (like creating dynamic variables and methods).  VS 2010’s pseudo-execution of code within the editor now allows us to provide rich intellisense for a much broader set of scenarios. For example, below we are using the browser’s window object to create a global variable named “bar”.  Notice how we can now get intellisense (with correct type inference for a string) with VS 2010 when we later try and use it: When we assign the “bar” variable as a number (instead of as a string) the VS 2010 intellisense engine correctly infers its type and modifies statement completion appropriately to be that of a number instead: Scenario 3: Showing Off Because VS 2010 is psudo-executing code within the editor, it is able to handle a bunch of scenarios (both practical and wacky) that you throw at it – and is still able to provide accurate type inference and intellisense. For example, below we are using a for-loop and the browser’s window object to dynamically create and name multiple dynamic variables (bar1, bar2, bar3…bar9).  Notice how the editor’s intellisense engine identifies and provides statement completion for them: Because variables added via the browser’s window object are also global variables – they also now show up in the global variable intellisense drop-down as well: Better yet – type inference is still fully supported.  So if we assign a string to a dynamically named variable we will get type inference for a string.  If we assign a number we’ll get type inference for a number.  Just for fun (and to show off!) we could adjust our for-loop to assign a string for even numbered variables (bar2, bar4, bar6, etc) and assign a number for odd numbered variables (bar1, bar3, bar5, etc): Notice above how we get statement completion for a string for the “bar2” variable.  Notice below how for “bar1” we get statement completion for a number:   This isn’t just a cool pet trick While the above example is a bit contrived, the approach of dynamically creating variables, methods and event handlers on the fly is pretty common with many Javascript libraries.  Many of the more popular libraries use these techniques to keep the size of script library downloads as small as possible.  VS 2010’s support for parsing and pseudo-executing libraries that use these techniques ensures that you get better code Intellisense out of the box when programming against them. Summary Visual Studio 2010 (and the free Visual Web Developer 2010 Express) now provide much richer JavaScript intellisense support.  This support works with pretty much all popular JavaScript libraries.  It should help provide a much better development experience when coding client-side JavaScript and enabling AJAX scenarios within your ASP.NET applications. Hope this helps, Scott P.S. You can read my previous blog post on VS 2008’s JavaScript Intellisense to learn more about our previous JavaScript intellisense (and some of the scenarios it supported).  VS 2010 obviously supports all of the scenarios previously enabled with VS 2008.

  • Writing C# Code Using SOLID Principles

    - by bipinjoshi
    Most of the modern programming languages including C# support objected oriented programming. Features such as encapsulation, inheritance, overloading and polymorphism are code level features. Using these features is just one part of the story. Equally important is to apply some object oriented design principles while writing your C# code. SOLID principles is a set of five such principles--namely Single Responsibility Principle, Open/Closed Principle, Liskov Substitution Principle, Interface Segregation Principle and Dependency Inversion Principle. Applying these time proven principles make your code structured, neat and easy to maintain. This article discusses SOLID principles and also illustrates how they can be applied to your C# code.http://www.binaryintellect.net/articles/7f857089-68f5-4d76-a3b7-57b898b6f4a8.aspx

  • Any experience with Mono on production servers?

    - by Jonas
    I am curios to use .NET for some web applications (e.g. ASP.NET MVC 2). However my budget is limited so I would like to use Mono on Linux. I have never used Mono before, and I haven't read about any bigger sites that is using Mono+Linux on the server in production. What's your experience using Mono on Linux in production? How is the performance and stability compared to .NET on Windows Server? Is there any popular sites that is using it in production? Any articles available online were they share their experiences?

  • MySQL for Excel 1.3.0 Beta has been released

    - by Javier Treviño
    The MySQL Windows Experience Team is proud to announce the release of MySQL for Excel version 1.3.0.  This is a beta release for 1.3.x. MySQL for Excel is an application plug-in enabling data analysts to very easily access and manipulate MySQL data within Microsoft Excel. It enables you to directly work with a MySQL database from within Microsoft Excel so you can easily do tasks such as: Importing MySQL data into Excel Exporting Excel data directly into MySQL to a new or existing table Editing MySQL data directly within Excel As this is a beta version the MySQL for Excel product can be downloaded only by using the product standalone installer at this link http://dev.mysql.com/downloads/windows/excel/ Your feedback on this beta version is very well appreciated, you can raise bugs on the MySQL bugs page or give us your comments on the MySQL for Excel forum. Changes in MySQL for Excel 1.3.0 (2014-06-06, Beta) This section documents all changes and bug fixes applied to MySQL for Excel since the release of 1.2.1. Several new features were added, for more information see What Is New In MySQL for Excel (http://dev.mysql.com/doc/refman/5.6/en/mysql-for-excel-what-is-new.html). Known limitations: Upgrading from versions MySQL for Excel 1.2.0 and lower is not possible due to a bug fixed in MySQL for Excel 1.2.1. In that scenario, the old version (MySQL for Excel 1.2.0 or lower) must be uninstalled first. Upgrading from version 1.2.1 works correctly. <CTRL> + <A> cannot be used to select all database objects. Either <SHIFT> + <Arrow Key> or <CTRL> + click must be used instead. PivotTables are normally placed to the right (skipping one column) of the imported data, they will not be created if there is another existing Excel object at that position. Functionality Added or Changed Imported data can now be refreshed by using the native Refresh feature. Fields in the imported data sheet are then updated against the live MySQL database using the saved connection ID. Functionality was added to import data directly into PivotTables, which can be created from any Import operation. Multiple objects (tables and views) can now be imported into Excel, when before only one object could be selected. Relational information is also utilized when importing multiple objects. All options now have descriptive tooltips. Hovering over an option/preference displays helpful information about its use. A new Export Data, Advanced Options option was added that shows all available data types in the Data Type combo box, instead of only showing a subset of the most popular data types. The option dialogs now include a Refresh to Defaults button that resets the dialog's options to their defaults values. Each option dialog is set individually. A new Add Summary Fields for Numeric Columns option was added to the Import Data dialog that automatically adds summary fields for numeric data after the last row of the imported data. The specific summary function is selectable from many options, such as "Total" and "Average." A new collation option was added for the schema and table creation wizards. The default schema collation is "Server Default", and the default table collation is "Schema Default". Collation options may be selected from a drop-down list of all available collations. Quick links: MySQL for Excel documentation: http://dev.mysql.com/doc/en/mysql-for-excel.html. MySQL on Windows blog: http://blogs.oracle.com/MySQLOnWindows.
