  • Adding Blog to Your Orchard Website

    - by hajan
    One of the common features in today’s content management systems is to provide you the ability to create your own blog in your website. Also, having a blog is one of the very often needed features for various types of websites. Out of the box, Orchard gives you this, so you can create your own blog in your Orchard website on a pretty easy way. Besides the fact that you can very easily create your own blog, Orchard also gives you some extra features in relation with the support of blogging, such as connecting third-party client applications (e.g. Windows Live Writer) to your blog, so that you can publish blog posts remotely. You can already find all the information provided in this blog post on the http://orchardproject.net website, however I thought it would be nice to make summary in one blog post. I assume you have already installed Orchard and you are already familiar with its environment and administration dashboard. If you haven’t, please read this blog post first.   CREATE YOUR BLOG First of all, go to Orchard Administration Dashboard and click on Blog in the left menu Once you are there, you will see the following screen   Fill the form with all needed data, as in the following example and click Save Right after, you should see the following screen Click New post, and add your first post. After that, go to Homepage (click Your Site in the top-left corner) and you should see the Blog link in your menu After clicking on Blog, you will be directed to the following page Once you click on My First Post, you will see that your blog already supports commenting ability (you can enable/disable this from Administration dashboard in your blog settings) Added comment Adding new comment Submit comment So, with following these steps, you have already setup your blog in your Orchard website.   CONNECT YOUR BLOG WITH WINDOWS LIVE WRITER Since many bloggers prepare their blog posts using third-party client applications, like Windows Live Writer, its very useful if your blog engine has the ability to work with these third-party applications and enable them to make remote posting and publishing. The client applications use XmlRpc interface in order to have the ability to manage and publish the blogs remotely. What is great about Orchard is that it gives you out of the box the XmlRpc and Remote Publishing modules. What you only need to do is to enable these features from the Modules in your Orchard Administration Dashboard. So, lets go through the steps of enabling and making your previously created blog able to work with third-party client applications for blogging. 1. Go to Administration Dashboard and click the Modules After clicking the Modules, you will see the following page: As you can see, you already have Remote Blog Publishing and XmlRpc features for Content Publishing, but both are disabled by default. So, if you click Enable only on Remote Blog Publishing, you will see both of them enabled at once since they are dependent features. After you click Enable, if everything is Ok, the following message should be displayed: So, now we have the featured enabled and ready... The next thing you need to do is to open Windows Live Writer. First, open Windows Live Writer and in your Blog Accounts, click on Add blog account In the next window, chose Other services After that, click on your Blog link in the Orchard website and copy the URL, my URL (on localhost development server) is: http://localhost:8191/blog Then, add your login credentials you use to login in Orchard and click Next. After that, if you have setup everything successfully, the Windows Live Writer will do the rest Once it finishes, you will have window where you can specify the name of your blog you have just connected your Windows Live Writer to... Then... you are done. You can see Windows Live Writer has detected the Orchard theme I am using After you finish with the blog post, click on Publish and refresh the Blog page in your Orchard website You see, we have the blog post directly posted from Windows Live Writer to my Orchard Blog. I hope this was useful blog post. Regards, Hajan Reference and other useful posts: Build incredible content-driven websites using Orchard CMS Create blog on your site with Orchard CMS Blogging using Windows Live Writer in your Orchard CMS Blog Orchard Website

  • A Few of My Favorite HTML5 and CSS3 Online Tools

    - by dwahlin
    I really enjoy coding up HTML5, CSS3, and JavaScript applications but there are some things that I’m better off writing with the help of a development tool. For example, CSS3 gradients aren’t exactly the most fun thing to write by hand and the same could be said for animations, transforms, or styles that require various vendor extensions. There are a lot of online tools that can simplify building HTML5/CSS3 sites and increase productivity in the process so I thought I’d put together a post on a few of my favorites tools. HTML5 Boilerplate HTML5 Boilerplate provides a great way to get started building HTML5 sites. It includes many best practices out of the box and even includes a few tricks that many people don’t even know about. The custom download option allows you to pick the features that you want to include in the files that’s generated. You can read more about it here.   Initializr Although HTML5 Boilerplate provides a great foundation for starting HTML5 sites, it focuses on providing a starting shell structure (namely an html page, JavaScript files, and a CSS stylesheet) and doesn’t include much in the way of page content to get started with. Initializer builds on HTML5 Boilerplate and provides an initial test page that can be tweaked to meet your needs. It also provides several different customization options to include/exclude features. CSS3 Maker CSS3 provides a lot of great features ranging from gradient support to rounded corners. Although many of the features are fairly straightforward there are some that are pretty involved such as gradients, animations, and really any styles that require custom vendor extensions to use across browsers. Sure, you can type everything by hand, but sites such as CSS3 Maker provide a visual way to generate CSS3 styles. CSS3, Please! CSS3, Please! is a code generation tool that can be used to generate cross-browser CSS3 styles quickly and easily. All of the main things you can do with CSS3 are available including a clever way to visually generate CSS3 transform styles.       Ultimate CSS Gradient Generator CSS3 Maker (above) has a gradient generator built-in but my favorite tool for creating CSS3 gradients is the Ultimate CSS Gradient Generator. If you’ve created gradients in tools like Photoshop then you’ll love what this tool has to offer especially since it makes it extremely straightforward to work with different gradient stops. @font-face Fonts Although @font-face has been available for awhile, I think fonts are cool and wanted to mention a site that provides a lot of font choices. When used correctly fonts can really enhance a page and when used incorrectly (think Comic Sans) they can absolutely ruin a page. Several sites exist that provide fonts that can be used with @font-face definitions in CSS style sheets. One of my favorites is Font Squirrel.   HTML5 & CSS3 Support and Tests Interested in knowing what HTML5 and CSS3 features a given browser supports? Want to know how various browsers stack up with each other as far as HTML5/CSS3 support. Look no further than the HTML5 & CSS3 Support page or the HTML5 Test page.   CSS3 Easing Animation Tool CSS3 animations aren’t widely supported across browsers right now (I’m not really using them at this point) but they do offer a lot of promise. Creating easings for animations can definitely be a challenge but they’re something that are critical for adding that “professional touch” to your animations. Fortunately you can use the Ceaser CSS Easing Animation Tool to simplify the process and handle animation easing with…...ease.   There are several other online tools that I like but these are some of the ones I find myself using the most. If you have any favorite online tools that simplify working with HTML5 or CSS3 let me know.     For more information about onsite or online training, mentoring and consulting solutions for HTML5, jQuery, .NET, SharePoint or Silverlight please visit http://www.thewahlingroup.com.

  • Dude, what’s up with POP Forums vNext?

    - by Jeff
    Yeah, it has been awhile. I posted v9.2 back in January, about five months ago. That’s a real change from the release pace I had there for awhile. Let me explain what’s going on. First off, in the interim, I re-launched CoasterBuzz, which required a lot of my attention for about two of those months. That’s a good thing though, because that site is just about the best test bed I could ask for. The other thing is that I committed to make the next version use ASP.NET MVC 4, which is now at the RC stage. I didn’t think much about when they’d hit their RTW point, but RC is good enough for me. To that end, there is enough change in the next version that I recently decided to make it a major version upgrade, and finish up the loose ends and science projects to make it whole. Here’s what’s in store… Mobile views: I sat on this or a long time. Originally, I was going to use jQuery Mobile, and waited and waited for a new release, but in the end, decided against using it. Sometimes buttons would unexplainably not work, I felt like I was fighting it at times, and the CSS just felt too heavy. I rolled my own mobile sugar at a fraction of the size, and I think you’ll find it easy to modify. And it’s Metro-y, of course! Re-do of background services: A number of things run in the background, and I did quite a bit of “reimagining” of that code. It’s the weirdness of running services in a Web site context, because so many folks can’t run a bona fide service on their host’s box. The biggest change here is that these service no longer start up by default. You’ll need to call a new method from global.asax called PopForumsActivation.StartServices(). This is also a precursor to running the app in a Web farm (new data layer and caching is the second part of that). I learned about this the hard way when I had three apps using the forum library code but only one was actually the forum. The services were all running three times as often with race conditions and hits on the same data. That was particularly bad for e-mail. CSS clean up: It’s still not ideal, but it’s getting better. That’s one of those things that comes with integrating to a real site… you discover all of the dumb things you did. The mobile CSS is particularly easier to live with. Bug fixes: There are a whole lot of them. Most were minor, but it’s feeling pretty solid now. So that’s where I am. I’m going to call it v10.0, and I’m going to really put forth some effort toward finishing the mobile experience and getting through the remaining bugs. The roadmap beyond that will likely not be feature oriented, but rather work on some other things, like making it run in Azure, perhaps using SQL CE, a better install experience, etc. As usual, I’ll post the latest here. Stay tuned!

  • Using Lambdas for return values in Rhino.Mocks

    - by PSteele
    In a recent StackOverflow question, someone showed some sample code they’d like to be able to use.  The particular syntax they used isn’t supported by Rhino.Mocks, but it was an interesting idea that I thought could be easily implemented with an extension method. Background When stubbing a method return value, Rhino.Mocks supports the following syntax: dependency.Stub(s => s.GetSomething()).Return(new Order()); The method signature is generic and therefore you get compile-time type checking that the object you’re returning matches the return value defined by the “GetSomething” method. You could also have Rhino.Mocks execute arbitrary code using the “Do” method: dependency.Stub(s => s.GetSomething()).Do((Func<Order>) (() => new Order())); This requires the cast though.  It works, but isn’t as clean as the original poster wanted.  They showed a simple example of something they’d like to see: dependency.Stub(s => s.GetSomething()).Return(() => new Order()); Very clean, simple and no casting required.  While Rhino.Mocks doesn’t support this syntax, it’s easy to add it via an extension method. The Rhino.Mocks “Stub” method returns an IMethodOptions<T>.  We just need to accept a Func<T> and use that as the return value.  At first, this would seem straightforward: public static IMethodOptions<T> Return<T>(this IMethodOptions<T> opts, Func<T> factory) { opts.Return(factory()); return opts; } And this would work and would provide the syntax the user was looking for.  But the problem with this is that you loose the late-bound semantics of a lambda.  The Func<T> is executed immediately and stored as the return value.  At the point you’re setting up your mocks and stubs (the “Arrange” part of “Arrange, Act, Assert”), you may not want the lambda executing – you probably want it delayed until the method is actually executed and Rhino.Mocks plugs in your return value. So let’s make a few small tweaks: public static IMethodOptions<T> Return<T>(this IMethodOptions<T> opts, Func<T> factory) { opts.Return(default(T)); // required for Rhino.Mocks on non-void methods opts.WhenCalled(mi => mi.ReturnValue = factory()); return opts; } As you can see, we still need to set up some kind of return value or Rhino.Mocks will complain as soon as it intercepts a call to our stubbed method.  We use the “WhenCalled” method to set the return value equal to the execution of our lambda.  This gives us the delayed execution we’re looking for and a nice syntax for lambda-based return values in Rhino.Mocks.

  • C#/.NET Little Wonders: The Timeout static class

    - by James Michael Hare
    Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. When I started the “Little Wonders” series, I really wanted to pay homage to parts of the .NET Framework that are often small but can help in big ways.  The item I have to discuss today really is a very small item in the .NET BCL, but once again I feel it can help make the intention of code much clearer and thus is worthy of note. The Problem - Magic numbers aren’t very readable or maintainable In my first Little Wonders Post (Five Little Wonders That Make Code Better) I mention the TimeSpan factory methods which, I feel, really help the readability of constructed TimeSpan instances. Just to quickly recap that discussion, ask yourself what the TimeSpan specified in each case below is 1: // Five minutes? Five Seconds? 2: var fiveWhat1 = new TimeSpan(0, 0, 5); 3: var fiveWhat2 = new TimeSpan(0, 0, 5, 0); 4: var fiveWhat3 = new TimeSpan(0, 0, 5, 0, 0); You’d think they’d all be the same unit of time, right?  After all, most overloads tend to tack additional arguments on the end.  But this is not the case with TimeSpan, where the constructor forms are:     TimeSpan(int hours, int minutes, int seconds);     TimeSpan(int days, int hours, int minutes, int seconds);     TimeSpan(int days, int hours, int minutes, int seconds, int milliseconds); Notice how in the 4 and 5 parameter version we suddenly have the parameter days slipping in front of hours?  This can make reading constructors like those above much harder.  Fortunately, there are TimeSpan factory methods to help make your intention crystal clear: 1: // Ah! Much clearer! 2: var fiveSeconds = TimeSpan.FromSeconds(5); These are great because they remove all ambiguity from the reader!  So in short, magic numbers in constructors and methods can be ambiguous, and anything we can do to clean up the intention of the developer will make the code much easier to read and maintain. Timeout – Readable identifiers for infinite timeout values In a similar way to TimeSpan, let’s consider specifying timeouts for some of .NET’s (or our own) many methods that allow you to specify timeout periods. For example, in the TPL Task class, there is a family of Wait() methods that can take TimeSpan or int for timeouts.  Typically, if you want to specify an infinite timeout, you’d just call the version that doesn’t take a timeout parameter at all: 1: myTask.Wait(); // infinite wait But there are versions that take the int or TimeSpan for timeout as well: 1: // Wait for 100 ms 2: myTask.Wait(100); 3:  4: // Wait for 5 seconds 5: myTask.Wait(TimeSpan.FromSeconds(5); Now, if we want to specify an infinite timeout to wait on the Task, we could pass –1 (or a TimeSpan set to –1 ms), which what the .NET BCL methods with timeouts use to represent an infinite timeout: 1: // Also infinite timeouts, but harder to read/maintain 2: myTask.Wait(-1); 3: myTask.Wait(TimeSpan.FromMilliseconds(-1)); However, these are not as readable or maintainable.  If you were writing this code, you might make the mistake of thinking 0 or int.MaxValue was an infinite timeout, and you’d be incorrect.  Also, reading the code above it isn’t as clear that –1 is infinite unless you happen to know that is the specified behavior. To make the code like this easier to read and maintain, there is a static class called Timeout in the System.Threading namespace which contains definition for infinite timeouts specified as both int and TimeSpan forms: Timeout.Infinite An integer constant with a value of –1 Timeout.InfiniteTimeSpan A static readonly TimeSpan which represents –1 ms (only available in .NET 4.5+) This makes our calls to Task.Wait() (or any other calls with timeouts) much more clear: 1: // intention to wait indefinitely is quite clear now 2: myTask.Wait(Timeout.Infinite); 3: myTask.Wait(Timeout.InfiniteTimeSpan); But wait, you may say, why would we care at all?  Why not use the version of Wait() that takes no arguments?  Good question!  When you’re directly calling the method with an infinite timeout that’s what you’d most likely do, but what if you are just passing along a timeout specified by a caller from higher up?  Or perhaps storing a timeout value from a configuration file, and want to default it to infinite? For example, perhaps you are designing a communications module and want to be able to shutdown gracefully, but if you can’t gracefully finish in a specified amount of time you want to force the connection closed.  You could create a Shutdown() method in your class, and take a TimeSpan or an int for the amount of time to wait for a clean shutdown – perhaps waiting for client to acknowledge – before terminating the connection.  So, assume we had a pub/sub system with a class to broadcast messages: 1: // Some class to broadcast messages to connected clients 2: public class Broadcaster 3: { 4: // ... 5:  6: // Shutdown connection to clients, wait for ack back from clients 7: // until all acks received or timeout, whichever happens first 8: public void Shutdown(int timeout) 9: { 10: // Kick off a task here to send shutdown request to clients and wait 11: // for the task to finish below for the specified time... 12:  13: if (!shutdownTask.Wait(timeout)) 14: { 15: // If Wait() returns false, we timed out and task 16: // did not join in time. 17: } 18: } 19: } We could even add an overload to allow us to use TimeSpan instead of int, to give our callers the flexibility to specify timeouts either way: 1: // overload to allow them to specify Timeout in TimeSpan, would 2: // just call the int version passing in the TotalMilliseconds... 3: public void Shutdown(TimeSpan timeout) 4: { 5: Shutdown(timeout.TotalMilliseconds); 6: } Notice in case of this class, we don’t assume the caller wants infinite timeouts, we choose to rely on them to tell us how long to wait.  So now, if they choose an infinite timeout, they could use the –1, which is more cryptic, or use Timeout class to make the intention clear: 1: // shutdown the broadcaster, waiting until all clients ack back 2: // without timing out. 3: myBroadcaster.Shutdown(Timeout.Infinite); We could even add a default argument using the int parameter version so that specifying no arguments to Shutdown() assumes an infinite timeout: 1: // Modified original Shutdown() method to add a default of 2: // Timeout.Infinite, works because Timeout.Infinite is a compile 3: // time constant. 4: public void Shutdown(int timeout = Timeout.Infinite) 5: { 6: // same code as before 7: } Note that you can’t default the ShutDown(TimeSpan) overload with Timeout.InfiniteTimeSpan since it is not a compile-time constant.  The only acceptable default for a TimeSpan parameter would be default(TimeSpan) which is zero milliseconds, which specified no wait, not infinite wait. Summary While Timeout.Infinite and Timeout.InfiniteTimeSpan are not earth-shattering classes in terms of functionality, they do give you very handy and readable constant values that you can use in your programs to help increase readability and maintainability when specifying infinite timeouts for various timeouts in the BCL and your own applications.

  • Binding a select in a client template

    - by Bertrand Le Roy
    I recently got a question on one of my client template posts asking me how to bind a select tag’s value to data in client templates. I was surprised not to find anything on the web addressing the problem, so I thought I’d write a short post about it. It really is very simple once you know where to look. You just need to bind the value property of the select tag, like this: <select sys:value="{binding color}"> If you do it from markup like here, you just need to use the sys: prefix. It just works. Here’s the full source code for my sample page: <!DOCTYPE html> <html> <head> <title>Binding a select tag</title> <script src=http://ajax.microsoft.com/ajax/beta/0911/Start.js type="text/javascript"></script> <script type="text/javascript"> Sys.require(Sys.scripts.Templates, function() { var colors = [ "red", "green", "blue", "cyan", "purple", "yellow" ]; var things = [ { what: "object", color: "blue" }, { what: "entity", color: "purple" }, { what: "thing", color: "green" } ]; Sys.create.dataView("#thingList", { data: things, itemRendered: function(view, ctx) { Sys.create.dataView( Sys.get("#colorSelect", ctx), { data: colors }); } }); }); </script> <style type="text/css"> .sys-template {display: none;} </style> </head> <body xmlns:sys="javascript:Sys"> <div> <ul id="thingList" class="sys-template"> <li> <span sys:id="thingName" sys:style-color="{binding color}" >{{what}}</span> <select sys:id="colorSelect" sys:value="{binding color}" class="sys-template"> <option sys:value="{{$dataItem}}" sys:style-background-color="{{$dataItem}}" >{{$dataItem}}</option> </select> </li> </ul> </div> </body> </html> This produces the following page: Each of the items sees its color change as you select a different color in the drop-down. Other details worth noting in this page are the use of the script loader to get the framework from the CDN, and the sys:style-background-color syntax to bind the background color style property from markup. Of course, I’ve used a fair amount of custom ASP.NET Ajax markup in here, but everything could be done imperatively and with completely clean markup from the itemRendered event using Sys.bind.

  • Azure Mobile Services: lessons learned

    - by svdoever
    When I first started using Azure Mobile Services I thought of it as a nice way to: authenticate my users - login using Twitter, Google, Facebook, Windows Live create tables, and use the client code to create the columns in the table because that is not possible in the Azure Mobile Services UI run some Javascript code on the table crud actions (Insert, Update, Delete, Read) schedule a Javascript to run any 15 or more minutes I had no idea of the magic that was happening inside… where is the data stored? Is it a kind of big table, are relationships between tables possible? those Javascripts on the table crud actions, is that interpreted, what is that exactly? After working for some time with Azure Mobile Services I became a lot wiser: Those tables are just normal tables in an Azure SQL Server 2012 Creating the table columns through client code sucks, at least from my Javascript code, because the columns are deducted from the sent JSON data, and a datetime field is sent as string in JSON, so a string type column is created instead of a datetime column You can connect with SQL Management Studio to the Azure SQL Server, and although you can’t manage your columns through the SQL Management Studio UI, it is possible to just run SQL scripts to drop and create tables and indices When you create a table through SQL script, add the table with the same name in the Azure Mobile Services UI to hook it up and be able to access the table through the provided abstraction layer You can also go to the SQL Database through the Azure Mobile Services UI, and from there get in a web based SQL management studio where you can create columns and manage your data The table crud scripts and the scheduler scripts are full blown node.js scripts, introducing a lot of power with great performance The web based script editor is really powerful, I do most of my editing currently in the editor which has syntax highlighting and code completing. While editing the code JsHint is used for script validation. The documentation on Azure Mobile Services is… suboptimal. It is such a pity that there is no way to comment on it so the community could fill in the missing holes, like which node modules are already loaded, and which modules are available on Azure Mobile Services. Soon I was hacking away on Azure Mobile Services, creating my own database tables through script, and abusing the read script of an empty table named query to implement my own set of “services”. The latest updates to Azure Mobile Services described in the following posts added some great new features like creating web API’s, use shared code from your scripts, command line tools for managing Azure Mobile Services (upload and download scripts for example), support for node modules and git support: http://weblogs.asp.net/scottgu/archive/2013/06/14/windows-azure-major-updates-for-mobile-backend-development.aspx http://blogs.msdn.com/b/carlosfigueira/archive/2013/06/14/custom-apis-in-azure-mobile-services.aspx http://blogs.msdn.com/b/carlosfigueira/archive/2013/06/19/custom-api-in-azure-mobile-services-client-sdks.aspx In the mean time I rewrote all my “service-like” table scripts to API scripts, which works like a breeze. Bad thing with the current state of Azure Mobile Services is that the git support is not working if you are a co-administrator of your Azure subscription, and not and administrator (as in my case). Another bad thing is that Cross Origin Request Sharing (CORS) is not supported for the API yet, so no go yet from the browser client for API’s, which is my case. See http://social.msdn.microsoft.com/Forums/windowsazure/en-US/2b79c5ea-d187-4c2b-823a-3f3e0559829d/known-limitations-for-source-control-and-custom-api-features for more on these and other limitations. In his talk at Build 2013 Josh Twist showed that there is a work-around for accessing shared script code from the table scripts as well (another limitation mentioned in the post above). I could not find that code in the Votabl2 code example from the presentation at https://github.com/joshtwist/votabl2, but we can grab it from the presentation when it comes online on Channel9. By the way: you can always express your needs and ideas at http://mobileservices.uservoice.com, that’s the place they are listening to (I hope!).

  • How To: Using spatial data with Entity Framework and Connector/Net

    - by GABMARTINEZ
    One of the new features introduced in Entity Framework 5.0 is the incorporation of some new types of data within an Entity Data Model: the spatial data types. These types allow us to perform operations on coordinates values in an easier way. There's no need to add stored routines or functions for every operation among these geometry types, now the user can have the alternative to put this logic on his application or keep it in the database. In the new 6.7.4 version there's also this new feature incorporated to Connector/Net library so our users can start exploring it and could provide us some feedback or comments about this new functionality. Through this tutorial on how to create a Code First Entity Model with a geometry column, we'll show an example on using Geometry types and some common operations when using geometry types inside an application. Requirements: - Connector/Net 6.7.4 - Entity Framework 5.0 version - .NET Framework 4.5 version - Basic understanding on Entity Framework and C# language. - An installed and running instance of MySQL Server 5.5.x or 5.6.10 version- Visual Studio 2012. Step One: Create a new Console Application  Inside Visual Studio select File->New Project menu option and select the Console Application template. Also make sure the .Net 4.5 version is selected so the new features for EF 5.0 will work with the application. Step Two: Add the Entity Framework Package For adding the Entity Framework Package there is more than one option: the package manager console or the Manage Nuget Packages option dialog. If you want to open the Package Manager Console, go to the Tools Menu -> Library Package Manager -> Package Manager Console. On the Package Manager Console Type:Install-Package EntityFrameworkThis will add the reference to the project of the latest released No alpha version of Entity Framework. Step Three: Adding Entity class and DBContext We'll add a simple class that represents a table entity to save some places and its location using a DBGeometry column that will be mapped to a Geometry type in MySQL. After that some operations can be performed using this data. public class MyPlace { [Key] public int Id { get; set; } public string name { get; set; } public DbGeometry location { get; set; } } public class JourneyDb : DbContext { public DbSet<MyPlace> MyPlaces { get; set; } }  Also make sure to add the connection string to the App.Config file as in the example: <?xml version="1.0" encoding="utf-8"?> <configuration>   <configSections>     <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->     <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />   </configSections>   <startup>     <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />   </startup>   <connectionStrings>     <add name="JourneyDb" connectionString="server=localhost;userid=root;pwd=;database=journeydb" providerName="MySql.Data.MySqlClient"/>   </connectionStrings>   <entityFramework>     </entityFramework> </configuration> Note also that the <entityFramework> section is empty.Step Four: Adding some new records.On the Program.cs file add the following code for the Main method so the Database gets created and also some new data can be added to the new table. This code adds some records containing some determinate locations. After being added a distance function will be used to know how much distance has each location in reference to the Queens Village Station in New York. static void Main(string[] args)    {     using (JourneyDb cxt = new JourneyDb())      {        cxt.Database.Delete();        cxt.Database.Create();         cxt.MyPlaces.Add(new MyPlace()        {          name = "JFK INTERNATIONAL AIRPORT OF NEW YORK",          location = DbGeometry.FromText("POINT(40.644047 -73.782291)"),        });         cxt.MyPlaces.Add(new MyPlace()        {          name = "ALLEY POND PARK",          location = DbGeometry.FromText("POINT(40.745696 -73.742638)"),        });       cxt.MyPlaces.Add(new MyPlace()        {          name = "CUNNINGHAM PARK",          location = DbGeometry.FromText("POINT(40.735031 -73.768387)"),        });         cxt.MyPlaces.Add(new MyPlace()        {          name = "QUEENS VILLAGE STATION",          location = DbGeometry.FromText("POINT(40.717957 -73.736501)"),        });         cxt.SaveChanges();         var points = (from p in cxt.MyPlaces                      select new { p.name, p.location });        foreach (var item in points)       {         Console.WriteLine("Location " + item.name + " has a distance in Km from Queens Village Station " + DbGeometry.FromText("POINT(40.717957 -73.736501)").Distance(item.location) * 100);       }       Console.ReadKey();      }  }}Output : Location JFK INTERNATIONAL AIRPORT OF NEW YORK has a distance from Queens Village Station 8.69448802402959 Km. Location ALLEY POND PARK has a distance from Queens Village Station 2.84097675104912 Km. Location CUNNINGHAM PARK has a distance from Queens Village Station 3.61695793727275 Km. Location QUEENS VILLAGE STATION has a distance from Queens Village Station 0 Km. Conclusion:Adding spatial data to a table is easier than before when having Entity Framework 5.0. This new Entity Framework feature that handles spatial data columns within the Data layer has a lot of integrated functions and methods toease this type of tasks.Notes:This version of Connector/Net is just released as GA so is preatty much stable to be used on a ProductionEnvironment. Please send us your comments or questions using this blog or at the Forums where we keep answering any questions you have about Connector/Net and MySQL Server.A copy of this sample project can be downloaded here. This application does not include any library so you will haveto add them before running it. Happly MySQL/.Net Coding.

  • Authenticating your windows domain users in the cloud

    - by cibrax
    Moving to the cloud can represent a big challenge for many organizations when it comes to reusing existing infrastructure. For applications that drive existing business processes in the organization, reusing IT assets like active directory represent good part of that challenge. For example, a new web mobile application that sales representatives can use for interacting with an existing CRM system in the organization. In the case of Windows Azure, the Access Control Service (ACS) already provides some integration with ADFS through WS-Federation. That means any organization can create a new trust relationship between the STS running in the ACS and the STS running in ADFS. As the following image illustrates, the ADFS running in the organization should be somehow exposed out of network boundaries to talk to the ACS. This is usually accomplish through an ADFS proxy running in a DMZ. This is the official story for authenticating existing domain users with the ACS.  Getting an ADFS up and running in the organization, which talks to a proxy and also trust the ACS could represent a painful experience. It basically requires  advance knowledge of ADSF and exhaustive testing to get everything right.  However, if you want to get an infrastructure ready for authenticating your domain users in the cloud in a matter of minutes, you will probably want to take a look at the sample I wrote for talking to an existing Active Directory using a regular WCF service through the Service Bus Relay Binding. You can use the WCF ability for self hosting the authentication service within a any program running in the domain (a Windows service typically). The service will not require opening any port as it is opening an outbound connection to the cloud through the Relay Service. In addition, the service will be protected from being invoked by any unauthorized party with the ACS, which will act as a firewall between any client and the service. In that way, we can get a very safe solution up and running almost immediately. To make the solution even more convenient, I implemented an STS in the cloud that internally invokes the service running on premises for authenticating the users. Any existing web application in the cloud can just establish a trust relationship with this STS, and authenticate the users via WS-Federation passive profile with regular http calls, which makes this very attractive for web mobile for example. This is how the WCF service running on premises looks like, [ServiceBehavior(Namespace = "http://agilesight.com/active_directory/agent")] public class ProxyService : IAuthenticationService { IUserFinder userFinder; IUserAuthenticator userAuthenticator;   public ProxyService() : this(new UserFinder(), new UserAuthenticator()) { }   public ProxyService(IUserFinder userFinder, IUserAuthenticator userAuthenticator) { this.userFinder = userFinder; this.userAuthenticator = userAuthenticator; }   public AuthenticationResponse Authenticate(AuthenticationRequest request) { if (userAuthenticator.Authenticate(request.Username, request.Password)) { return new AuthenticationResponse { Result = true, Attributes = this.userFinder.GetAttributes(request.Username) }; }   return new AuthenticationResponse { Result = false }; } } Two external dependencies are used by this service for authenticating users (IUserAuthenticator) and for retrieving user attributes from the user’s directory (IUserFinder). The UserAuthenticator implementation is just a wrapper around the LogonUser Win Api. The UserFinder implementation relies on Directory Services in .NET for searching the user attributes in an existing directory service like Active Directory or the local user store. public UserAttribute[] GetAttributes(string username) { var attributes = new List<UserAttribute>();   var identity = UserPrincipal.FindByIdentity(new PrincipalContext(this.contextType, this.server, this.container), IdentityType.SamAccountName, username); if (identity != null) { var groups = identity.GetGroups(); foreach(var group in groups) { attributes.Add(new UserAttribute { Name = "Group", Value = group.Name }); } if(!string.IsNullOrEmpty(identity.DisplayName)) attributes.Add(new UserAttribute { Name = "DisplayName", Value = identity.DisplayName }); if(!string.IsNullOrEmpty(identity.EmailAddress)) attributes.Add(new UserAttribute { Name = "EmailAddress", Value = identity.EmailAddress }); }   return attributes.ToArray(); } As you can see, the code is simple and uses all the existing infrastructure in Azure to simplify a problem that looks very complex at first glance with ADFS. All the source code for this sample is available to download (or change) in this GitHub repository, https://github.com/AgileSight/ActiveDirectoryForCloud

  • Open source adventures with... wait for it... Microsoft

    - by Jeff
    Last week, Microsoft announced that it was going to open source the rest of the ASP.NET MVC Web stack. The core MVC framework has been open source for a long time now, but the other pieces around it are also now out in the wild. Not only that, but it's not what I call "big bang" open source, where you release the source with each version. No, they're actually committing in real time to a public repository. They're also taking contributions where it makes sense. If that weren't exciting enough, CodePlex, which used to be a part of the team I was on, has been re-org'd to a different part of the company where it is getting the love and attention (and apparently money) that it deserves. For a period of several months, I lobbied to get a PM gig with that product, but got nowhere. A year and a half later, I'm happy to see it finally treated right. In any case, I found a bug in Razor, the rendering engine, before the beta came out. I informally sent the bug info to some people, but it wasn't fixed for the beta. Now, with the project being developed in the open, I was able to submit the issue, and went back and forth with the developer who wrote the code (I met him once at a meet up in Bellevue, I think), and he committed a fix. I tried it a day later, and the bug was gone. There's a lot to learn from all of this. That open source software is surprisingly efficient and often of high quality is one part of it. For me the win is that it demonstrates how open and collaborative processes, as light as possible, lead to better software. In other words, even if this were a project being developed internally, at a bank or something, getting stakeholders involved early and giving people the ability to respond leads to awesomeness. While there is always a place for big thinking, experience has shown time and time again that trying to figure everything out up front takes too long, and rarely meets expectations. This is a lesson that probably half of Microsoft has yet to learn, including the team I was on before I split. It's the reason that team still hasn't shipped anything to general availability. But I've seen what an open and iterative development style can do for teams, at Microsoft and other places that I've worked. When you can have a conversation with people, and take ideas and turn them into code quickly, you're winning. So why don't people like winning? I think there are a lot of reasons, and they can generally be categorized into fear, skepticism and bad experiences. I can't give the Web stack teams enough credit. Not only did they dream big, but they changed a culture that often seems immovable and hopelessly stuck. This is a very public example of this culture change, but it's starting to happen at every scale in Microsoft. It's really interesting to see in a company that has been written off as dead the last decade.

  • Getting Started with jqChart for ASP.NET Web Forms

    - by jqChart
    Official Site | Samples | Download | Documentation | Forum | Twitter Introduction jqChart takes advantages of HTML5 Canvas to deliver high performance client-side charts and graphs across browsers (IE 6+, Firefox, Chrome, Opera, Safari) and devices, including iOS and Android mobile devices. Some of the key features are: High performance rendering. Animaitons. Scrolling/Zoooming. Support for unlimited number of data series and data points. Support for unlimited number of chart axes. True DateTime Axis. Logarithmic and Reversed axis scale. Large set of chart types - Bar, Column, Pie, Line, Spline, Area, Scatter, Bubble, Radar, Polar. Financial Charts - Stock Chart and Candlestick Chart. The different chart types can be easily combined.  System Requirements Browser Support jqChart supports all major browsers: Internet Explorer - 6+ Firefox Google Chrome Opera Safari jQuery version support jQuery JavaScript framework is required. We recommend using the latest official stable version of the jQuery library. Visual Studio Support jqChart for ASP.NET does not require using Visual Studio. You can use your favourite code editor. Still, the product has been tested with several versions of Visual Studio .NET and you can find the list of supported versions below: Visual Studio 2008 Visual Studio 2010 Visual Studio 2012 ASP.NET Web Forms support Supported version - ASP.NET Web Forms 3.5, 4.0 and 4.5 Installation Download and unzip the contents of the archive to any convenient location. The package contains the following folders: [bin] - Contains the assembly DLLs of the product (JQChart.Web.dll) for WebForms 3.5, 4.0 and 4.5. This is the assembly that you can reference directly in your web project (or better yet, add it to your ToolBox and then drag & drop it from there). [js] - The javascript files of jqChart and jqRangeSlider (and the needed libraries). You need to include them in your ASPX page, in order to gain the client side functionality of the chart. The first file is "jquery-1.5.1.min.js" - this is the official jQuery library. jqChart is built upon jQuery library version 1.4.3. The second file you need is the "excanvas.js" javascript file. It is used from the versions of IE, which dosn't support canvas graphics. The third is the jqChart javascript code itself, located in "jquery.jqChart.min.js". The last one is the jqRangeSlider javascript, located in "jquery.jqRangeSlider.min.js". It is used when the chart zooming is enabled. [css] - Contains the Css files that the jqChart and the jqRangeSlider need. [samples] - Contains some examples that use the jqChart. For full list of samples plese visit - jqChart for ASP.NET Samples. [themes] - Contains the themes shipped with the products. It is used from the jqRangeSlider. Since jqRangeSlider supports jQuery UI Themeroller, any theme compatible with jQuery UI ThemeRoller will work for jqRangeSlider as well. You can download any additional themes directly from jQuery UI's ThemeRoller site available here: http://jqueryui.com/themeroller/ or reference them from Microsoft's / Google's CDN. <link rel="stylesheet" type="text/css" media="screen" href="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.21/themes/smoothness/jquery-ui.css" /> The final result you will have in an ASPX page containing jqChart would be something similar to that (assuming you have copied the [js] to the Script folder and [css] to Content folder of your ASP.NET site respectively). <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="samples_cs.Default" %> <%@ Register Assembly="JQChart.Web" Namespace="JQChart.Web.UI.WebControls" TagPrefix="jqChart" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html > <head runat="server"> <title>jqChart ASP.NET Sample</title> <link rel="stylesheet" type="text/css" href="~/Content/jquery.jqChart.css" /> <link rel="stylesheet" type="text/css" href="~/Content/jquery.jqRangeSlider.css" /> <link rel="stylesheet" type="text/css" href="~/Content/themes/smoothness/jquery-ui-1.8.21.css" /> <script src="<% = ResolveUrl("~/Scripts/jquery-1.5.1.min.js") %>" type="text/javascript"></script> <script src="<% = ResolveUrl("~/Scripts/jquery.jqRangeSlider.min.js") %>" type="text/javascript"></script> <script src="<% = ResolveUrl("~/Scripts/jquery.jqChart.min.js") %>" type="text/javascript"></script> <!--[if IE]><script lang="javascript" type="text/javascript" src="<% = ResolveUrl("~/Scripts/excanvas.js") %>"></script><![endif]--> </head> <body> <form id="form1" runat="server"> <asp:ObjectDataSource ID="ObjectDataSource1" runat="server" SelectMethod="GetData" TypeName="SamplesBrowser.Models.ChartData"></asp:ObjectDataSource> <jqChart:Chart ID="Chart1" Width="500px" Height="300px" runat="server" DataSourceID="ObjectDataSource1"> <Title Text="Chart Title"></Title> <Animation Enabled="True" Duration="00:00:01" /> <Axes> <jqChart:CategoryAxis Location="Bottom" ZoomEnabled="true"> </jqChart:CategoryAxis> </Axes> <Series> <jqChart:ColumnSeries XValuesField="Label" YValuesField="Value1" Title="Column"> </jqChart:ColumnSeries> <jqChart:LineSeries XValuesField="Label" YValuesField="Value2" Title="Line"> </jqChart:LineSeries> </Series> </jqChart:Chart> </form> </body> </html>   Official Site | Samples | Download | Documentation | Forum | Twitter

  • 32bit vs 64bit guest VM and RAM usage

    - by sims
    Why does a 32bit domU (Xen guest VM) use less RAM than a 64bit? Notes: The same software complied for a different arch(AMD64 vs. 686). Obviously this is Linux or BSD or something easily ported. Maybe this is also a good one for SO. I've read this is so. I can guess why, but I'd like to hear everyone's comments.

    - by sumek
    I've got a nagios server setup for monitoring ~ 30 Windows servers. I want to add some trending charts. I've read that nagios graphing plugins are simple and many people use seperate, standalone charting/trending tools. What are the restrictions of the nagios graphing plugins vs standalone products like ganglia/munin/cacti? I'm interested in specific features and advantages that standalone packages offer and nagios graphing plugins don't.

  • VMWare Player vs Workstation

    - by Anjisan
    What's the difference between VMWare Player vs Workstation? Is it that Player is for non-commercial use and workstation isn't? For someone who builds and tests applications at home for non-commercial use, is it worth paying for a Workstation license? Do I get any benefits over Player? (Note: I realize there's open source solutions like VirtualBox, but am more interested in the differences between Player and Workstation.) Thanks!
