  • Is SOA really dead?

    - by Ahsan Alam
    I have come across many articles/blogs where authors have strongly hailed the death of Service Oriented Architecture (SOA). I could almost hear the laughter pouring out of their writings. Being a big supporter of SOA, I have found myself wondering – have I been following the wrong path all along? Do I need to change the way I think? Then I started to look around. Many newer technologies and concepts have evolved in the past few years. People are starting to take advantage of cloud computing, SAAS (Software as a Service), multitudes of on-demand platforms and many more. Now, I started thinking – is SOA really dead? In order to effectively utilize these newer concepts, I believe we need SOA more than ever because it gives us loose-coupling. People often forget that the key principal behind SOA is loose-coupling. We cannot achieve SOA just by throwing services (WCF, Web Service); we need loosely coupled systems.

  • Reset the controls within asp placeholder

    - by alaa9jo
    I use placeholders very much in many projects,but in one of the projects I was asked to reset the controls within a specific placeholder to their original state after the user has finished from inserting his/her data. As everyone of us know,to keep the controls within a placeholder from disappearing after postbacks you have to recreate them,we add such a code in i.e. page_load,the controls will be recreated and their values will be loaded from viewstate (for some of them like textbox,checkboxs,..etc) automatically,that placeholder contains only textboxs so what I need is to block/ loading/clear that viewstate after inserting the data. First thought: Customizing placeholder I thought about it and tried overriding many methods but no success at all...maybe I'm missing something not sure. Second thought: recreate the controls 2 times: In page_load,I recreate the controls within that placeholder then in button click (the button that saves user's data) I recreate them once more and it worked! I just thought of sharing my experience in that case with everyone in case anyone needed it,any better suggestion(s) is welcomed.

  • Stir Trek: Iron Man Edition Recap and Photos

    - by Brian Jackett
    If you’ve noticed my blogging activity has reduced in frequency and technical content lately it’s primarily due to all of the conferences I’ve been attending, speaking at, or planning in the past few months.  This past Friday myself and six other dedicated individuals put on Stir Trek: Iron Man Edition as the culmination of a few months of hard work.  For those unfamiliar, Stir Trek is a web developer conference that was founded last year as an event to showcase content from Microsoft’s MIX conference and end the day with a private showing of the then just-released Star Trek movie.  This year’s conference expanded from 2 to 4 content tracks and upped the number of tickets from 350 to 600.  Even more amazing was the fact that we had 592 people show up day of the event for the lowest drop-off percentage of any conference I’ve been to before.   Nerd Dinner and Swag Bags     The night before Stir Trek: Iron Man Edition we hosted a nerd dinner at the Polaris Shopping mall food court with about 30 in attendance.  Nerd dinners are a great time to meet others passionate about technology and socialize before the whirlwind of the conference hits.  After the nerd dinner 20+ volunteers headed to the conference location and helped us stuff swag bags.  This in and of itself was a monumental task of putting together 600 swag bags with numerous leaflets, sponsor items, and t-shirts.  A big thanks goes out to all who assisted us that night so that we could finish in just under 2 hours instead of taking all night.  My sleep schedule also thanks you. Morning of Stir Trek     After getting a decent amount of sleep I arrived at Marcus Crosswoods theater at 6am to begin setting up for the day.  Myself and Jody Morgan were in charge of registration so we got tables set up, laid out swag bags, and organized our volunteer crew to assist with checking-in attendees.  Despite having 600+ people registration went fairly smoothly and got the day off to a great start.  I especially appreciated the 3+ cups of coffee from Crimson Cup, a local coffee shop.  For any of you that know me you’ll know that I rarely drink coffee except a few times a year when I really need the energy, so that says a lot about how good their coffee is.   Conference Starts     Once registration was completed the day kicked off with Molly Holzschlag keynoting.  Unfortunately Molly suffered from an ear infection and wasn’t able to fly so she had a virtual keynote and a session later in the day.  I was working behind the scenes on various tasks so I was only able to drop in very briefly on the keynote and rest of the morning sessions.  Throughout the day I tried to grab at least 1 or 2 pics of each presenter.  See my album below for the full set of pics.      For lunch we ordered around 150 pizzas from Mellow Mushroom, a local pizza place (notice the theme of supporting local businesses.)  Early on we were concerned about Mellow Mushroom being able to supply that many pizzas and get them delivered (still hot) to the theater, but they did an excellent job day of the event.  I wish I had gotten some pictures of the old school VW van they delivered the pizza in, but I was just a bit busy running around trying to get theaters ready for lunch.  We had attendees from last year who specifically requested that we have Mellow Mushroom supply lunch this year and I’m glad everything worked out being able to use them again.     During the afternoon I was able to attend a few sessions and hear some great content from various speakers.  It was also nice to just sit down and get off my feet for a bit.  After the last sessions the day concluded with a raffle.  There were a few logistical and technical issues that hampered our ability to smoothly conduct the raffle.  To those of you that agree the raffle wasn’t the smoothest experience I would like to say that the Stir Trek planning committee has already begun meeting to discuss ways of improving the conference for next year.  We are also accepting feedback (both positive and negative) at the following link: click here.  If you don’t wish to use the Joind In site you can also email me directly and I’ll be sure to pass along the feedback.   Iron Man 2 Movie     Last but not least, what Stir Trek event would be complete without the feature movie.  This year’s movie was Iron Man 2.  The theater had some really cool props and promotions (see pic below) for the movie.  I really enjoyed Iron Man 2, but I would recommend brushing up on the Iron Man comics and Marvel’s plans for future movies to understand some of the plot elements that come up.  Also make sure you stay through to the end of the movie credits to see a sneak peak of something special, that’s all I’ll say. Conclusion     Again a big thanks goes out to all of the speakers, sponsors, attendees, movie theater staff, volunteers, and everyone else involved in making this event great.  Also big thanks to my fellow Stir Trek planning committee members: Jeff Blankenburg, Matt Casto, Carey Payette, Jody Morgan, Rick Kierner, and Sarah Dutkiewitcz.  I am grateful for everything I learned while helping plan this event and look forward to being involved again next year.  For those interested we are currently targeting Thor as our movie theme for 2011 and then The Avengers for 2012.  These are tentative based on release dates that could shift as we get closer, but for now look solid.   Photos Pics on Facebook (includes tagging)     Stir Trek: Iron Man Edition photos on Facebook Pics on Live site (higher res)      View Full Album         -Frog Out

  • How to change ownership of a domain name from "missing" web designer

    - by Stuart
    Hi, We had a website produced a few years ago with a .ORG domain name. The site hadn't grown with our needs, so we've now got a new .co.uk site. Our intention was to transfer the .org address to the new site on completion. Our new site is to go live soon, but the original .ORG site has gone offline (hosting expired I believe as the expiry date for the .ORG is in 2012) and we now discover that the .ORG domain name is registered to the web designer and not to anyone in our organisation. The WHOIS information gives us the technical contact as discountasp.net. What are the steps we can take here? Our primary concern is getting the name servers changed (the current .ORG address goes nowhere) and ultimately we need to transfer ownership? The organisation in question is a community, non-profit organisation, so our pockets are not deep. Thanks in advance for any help. Stuart.

  • Mac OS X printing to CUPS - More intuitive authentication failure?

    - by Moduspwnens
    We have a network-wide CUPS server that offers authenticated printer access to all our campus users. We've been pretty disappointed with the way Mac clients handle bad printing authentication, though. In any other authentication dialog, when a user types in a bad username or password, the window shakes briefly, allowing the user to re-enter. With printers, this isn't the case. It'll happily accept (and even save to the keychain, if specified) bad credentials. The authentication dialog is dismissed, and the user then has to deal with the print jobs showing up as "On hold (authentication required)". To get their job printed, they need to select it in the printer's queue, click "Resume", then re-enter appropriate credentials. Is there a way to get failed printing authentication to work more intuitively for Mac OS X clients? We're trying to support a BYOD environment, but our end users have been really confused by this. It's made even worse by the way it pre-populates the user's full login name (e.g. "Smith, John"), which tends to make them think to use their local machine passwords.

  • What are the major challenges in creating a platform such as StackOverflow?

    - by gablin
    Let us assume you were to create a platform such as StackOverflow. It needs to be functional, fast and scalable, just like SO, in order to be successful. What are the major challenges you would face in such a task? I'm looking for technical challenges rather than problems such as how to advertise it and stuff like that. (I'm not looking for ways of creating a new site to challenge SO; I'm just interested in how difficult it would be to create it if it didn't already exist.)

  • Amazon SOA: database as a Service

    - by Martin Lee
    There is an interesting interview with Werner Vogels which is partly about how Amazon does Service Oriented Architecture: For us service orientation means encapsulating the data with the business logic that operates on the data, with the only access through a published service interface. No direct database access is allowed from outside the service, and there’s no data sharing among the services. I do not understand that. Why do they need to 'wrap' a database into some layer if it already can be consumed as a service by other service through database adaptors? Does Amazon do that just because they need to expose the database to third parties or because of anything else? Why "no direct database access is allowed"? What are the advantages of such an architectural decision?

  • How To Enlarge a Virtual Machine’s Disk in VirtualBox or VMware

    - by Chris Hoffman
    When you create a virtual hard disk in VirtualBox or VMware, you specify a maximum disk size. If you want more space on your virtual machine’s hard disk later, you’ll have to enlarge the virtual hard disk and partition. Note that you may want to back up your virtual hard disk file before performing these operations – there’s always a chance something can go wrong, so it’s always good to have backups. However, the process worked fine for us.

  • Execute TSQL statement with ExecuteStoreQuery in entity framework 4.0

    - by Jalpesh P. Vadgama
    I was playing with entity framework in recent days and I was searching something that how we can execute TSQL statement in entity framework. And I have found one great way to do that with entity framework ‘ExecuteStoreQuery’ method. It’s executes a TSQL statement against data source given enity framework context and returns strongly typed result. You can find more information about ExcuteStoreQuery from following link. http://msdn.microsoft.com/en-us/library/dd487208.aspx So let’s examine how it works. So Let’s first create a table against which we are going to execute TSQL statement. So I have added a SQL Express database as following. Now once we are done with adding a database let’s add a table called Client like following. Here you can see above Client table is very simple. There are only two fields ClientId and ClientName where ClientId is primary key and ClientName is field where we are going to store client name. Now it’s time to add some data to the table. So I have added some test data like following. Now it’s time to add entity framework model class. So right click project->Add new item and select ADO.NET entity model as following. After clicking on add button a wizard will start it will ask whether we need to create model classes from database or not but we already have our client table ready so I have selected generate from database as following. Once you process further in wizard it will be presented a screen where we can select the our table like following. Now once you click finish it will create model classes with for us. Now we need a gridview control where we need to display those data. So in Default.aspx page I have added a grid control like following. <%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="EntityFramework._Default" %> <asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent"> </asp:Content> <asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent"> <h2> Welcome to ASP.NET! </h2> <p> To learn more about ASP.NET visit <a href="http://www.asp.net" title="ASP.NET Website">www.asp.net</a>. </p> <p> You can also find <a href="http://go.microsoft.com/fwlink/?LinkID=152368&amp;clcid=0x409" title="MSDN ASP.NET Docs">documentation on ASP.NET at MSDN</a>. <asp:GridView ID="grdClient" runat="server"> </asp:GridView> </p> </asp:Content> Now once we are done with adding Gridview its time to write code for server side. So I have written following code in Page_load event of default.aspx page. protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { using (var context = new EntityFramework.TestEntities()) { ObjectResult<Client> result = context.ExecuteStoreQuery<Client>("Select * from Client"); grdClient.DataSource = result; grdClient.DataBind(); } } } Here in the above code you can see that I have written create a object of our entity model and then with the help of the ExecuteStoreQuery method I have execute a simple select TSQL statement which will return a object result. I have bind that object result with gridview to display data. So now we are done with coding.So let’s run application in browser. Following is output as expected. That’s it. Hope you like it. Stay tuned for more..Till then happy programming.

  • Programming Test

    - by Travis Webb
    We are looking to hire some more Java developers onto our team, and plan to test their coding abilities with a test. We currently use a web-based Java test that automatically compiles and runs the code, but it is very flaky and we're having problems with our candidates losing their work on this site. Not only is this frustrating for everyone, it makes us look like we don't know what we're doing. Is there a popular testing suite out there? What do you use? I'm not interested in dogmatic arguments on whether or not I should be testing my candidates in this way, I'm looking for a tool that will help me do it.

  • Does the deprecation of mysql_* functions in PHP carry over to other Databases(MSSQL)?

    - by MobyD
    I'm not talking about MySQL, I'm talking about Microsoft SQL Server I've been aware of PDO for quite some time now, standard mysql functions are dangerous and should be avoided. http://php.net/manual/en/function.mysql-connect.php But what about the MSSQL function in PHP? They are, for most purposes, identical sets of functions, but the PHP page describing mssql_* carries no warning of deprecation. http://us.php.net/manual/en/function.mssql-connect.php There are PDO drivers available for MSSQL, but they aren't quite as readily available or used as the MySQL drivers. Ideally, it looks to me like I should get them working and move from mssql_* to PDO like I have with MySQL, but is it as big of a priority? Is there some hidden safety to MSSQL that means it's exempt from all of the mysql_* hatred as of late? Or is its obscurity as a backend the only reason there hasn't been more PDO encouragement?

  • SQL SERVER – What is Incremental Statistics? – Performance improvements in SQL Server 2014 – Part 1

    - by Pinal Dave
    This is the first part of the series Incremental Statistics. Here is the index of the complete series. What is Incremental Statistics? – Performance improvements in SQL Server 2014 – Part 1 Simple Example of Incremental Statistics – Performance improvements in SQL Server 2014 – Part 2 DMV to Identify Incremental Statistics – Performance improvements in SQL Server 2014 – Part 3 Statistics are considered one of the most important aspects of SQL Server Performance Tuning. You might have often heard the phrase, with related to performance tuning. “Update Statistics before you take any other steps to tune performance”. Honestly, I have said above statement many times and many times, I have personally updated statistics before I start to do any performance tuning exercise. You may agree or disagree to the point, but there is no denial that Statistics play an extremely vital role in the performance tuning. SQL Server 2014 has a new feature called Incremental Statistics. I have been playing with this feature for quite a while and I find that very interesting. After spending some time with this feature, I decided to write about this subject over here. New in SQL Server 2014 – Incremental Statistics Well, it seems like lots of people wants to start using SQL Server 2014′s new feature of Incremetnal Statistics. However, let us understand what actually this feature does and how it can help. I will try to simplify this feature first before I start working on the demo code. Code for all versions of SQL Server Here is the code which you can execute on all versions of SQL Server and it will update the statistics of your table. The keyword which you should pay attention is WITH FULLSCAN. It will scan the entire table and build brand new statistics for you which your SQL Server Performance Tuning engine can use for better estimation of your execution plan. UPDATE STATISTICS TableName(StatisticsName) WITH FULLSCAN Who should learn about this? Why? If you are using partitions in your database, you should consider about implementing this feature. Otherwise, this feature is pretty much not applicable to you. Well, if you are using single partition and your table data is in a single place, you still have to update your statistics the same way you have been doing. If you are using multiple partitions, this may be a very useful feature for you. In most cases, users have multiple partitions because they have lots of data in their table. Each partition will have data which belongs to itself. Now it is very common that each partition are populated separately in SQL Server. Real World Example For example, if your table contains data which is related to sales, you will have plenty of entries in your table. It will be a good idea to divide the partition into multiple filegroups for example, you can divide this table into 3 semesters or 4 quarters or even 12 months. Let us assume that we have divided our table into 12 different partitions. Now for the month of January, our first partition will be populated and for the month of February our second partition will be populated. Now assume, that you have plenty of the data in your first and second partition. Now the month of March has just started and your third partition has started to populate. Due to some reason, if you want to update your statistics, what will you do? In SQL Server 2012 and earlier version You will just use the code of WITH FULLSCAN and update the entire table. That means even though you have only data in third partition you will still update the entire table. This will be VERY resource intensive process as you will be updating the statistics of the partition 1 and 2 where data has not changed at all. In SQL Server 2014 You will just update the partition of Partition 3. There is a special syntax where you can now specify which partition you want to update now. The impact of this is that it is smartly merging the new data with old statistics and update the entire statistics without doing FULLSCAN of your entire table. This has a huge impact on performance. Remember that the new feature in SQL Server 2014 does not change anything besides the capability to update a single partition. However, there is one feature which is indeed attractive. Previously, when table data were changed 20% at that time, statistics update were triggered. However, now the same threshold is applicable to a single partition. That means if your partition faces 20% data, change it will also trigger partition level statistics update which, when merged to your final statistics will give you better performance. In summary If you are not using a partition, this feature is not applicable to you. If you are using a partition, this feature can be very helpful to you. Tomorrow: We will see working code of SQL Server 2014 Incremental Statistics.

  • Calculated Columns in Entity Framework Code First Migrations

    - by David Paquette
    I had a couple people ask me about calculated properties / columns in Entity Framework this week.  The question was, is there a way to specify a property in my C# class that is the result of some calculation involving 2 properties of the same class.  For example, in my database, I store a FirstName and a LastName column and I would like a FullName property that is computed from the FirstName and LastName columns.  My initial answer was: 1: public string FullName 2: { 3: get { return string.Format("{0} {1}", FirstName, LastName); } 4: } Of course, this works fine, but this does not give us the ability to write queries using the FullName property.  For example, this query: 1: var users = context.Users.Where(u => u.FullName.Contains("anan")); Would result in the following NotSupportedException: The specified type member 'FullName' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported. It turns out there is a way to support this type of behavior with Entity Framework Code First Migrations by making use of Computed Columns in SQL Server.  While there is no native support for computed columns in Code First Migrations, we can manually configure our migration to use computed columns. Let’s start by defining our C# classes and DbContext: 1: public class UserProfile 2: { 3: public int Id { get; set; } 4: 5: public string FirstName { get; set; } 6: public string LastName { get; set; } 7: 8: [DatabaseGenerated(DatabaseGeneratedOption.Computed)] 9: public string FullName { get; private set; } 10: } 11: 12: public class UserContext : DbContext 13: { 14: public DbSet<UserProfile> Users { get; set; } 15: } The DatabaseGenerated attribute is needed on our FullName property.  This is a hint to let Entity Framework Code First know that the database will be computing this property for us. Next, we need to run 2 commands in the Package Manager Console.  First, run Enable-Migrations to enable Code First Migrations for the UserContext.  Next, run Add-Migration Initial to create an initial migration.  This will create a migration that creates the UserProfile table with 3 columns: FirstName, LastName, and FullName.  This is where we need to make a small change.  Instead of allowing Code First Migrations to create the FullName property, we will manually add that column as a computed column. 1: public partial class Initial : DbMigration 2: { 3: public override void Up() 4: { 5: CreateTable( 6: "dbo.UserProfiles", 7: c => new 8: { 9: Id = c.Int(nullable: false, identity: true), 10: FirstName = c.String(), 11: LastName = c.String(), 12: //FullName = c.String(), 13: }) 14: .PrimaryKey(t => t.Id); 15: Sql("ALTER TABLE dbo.UserProfiles ADD FullName AS FirstName + ' ' + LastName"); 16: } 17: 18: 19: public override void Down() 20: { 21: DropTable("dbo.UserProfiles"); 22: } 23: } Finally, run the Update-Database command.  Now we can query for Users using the FullName property and that query will be executed on the database server.  However, we encounter another potential problem. Since the FullName property is calculated by the database, it will get out of sync on the object side as soon as we make a change to the FirstName or LastName property.  Luckily, we can have the best of both worlds here by also adding the calculation back to the getter on the FullName property: 1: [DatabaseGenerated(DatabaseGeneratedOption.Computed)] 2: public string FullName 3: { 4: get { return FirstName + " " + LastName; } 5: private set 6: { 7: //Just need this here to trick EF 8: } 9: } Now we can both query for Users using the FullName property and we also won’t need to worry about the FullName property being out of sync with the FirstName and LastName properties.  When we run this code: 1: using(UserContext context = new UserContext()) 2: { 3: UserProfile userProfile = new UserProfile {FirstName = "Chanandler", LastName = "Bong"}; 4: 5: Console.WriteLine("Before saving: " + userProfile.FullName); 6: 7: context.Users.Add(userProfile); 8: context.SaveChanges(); 9:  10: Console.WriteLine("After saving: " + userProfile.FullName); 11:  12: UserProfile chanandler = context.Users.First(u => u.FullName == "Chanandler Bong"); 13: Console.WriteLine("After reading: " + chanandler.FullName); 14:  15: chanandler.FirstName = "Chandler"; 16: chanandler.LastName = "Bing"; 17:  18: Console.WriteLine("After changing: " + chanandler.FullName); 19:  20: } We get this output: It took a bit of work, but finally Chandler’s TV Guide can be delivered to the right person. The obvious downside to this implementation is that the FullName calculation is duplicated in the database and in the UserProfile class. This sample was written using Visual Studio 2012 and Entity Framework 5. Download the source code here.

  • MYSQL – Detecting Current Version of MySQL Server Installation

    - by Pinal Dave
    Here is one of the most popular questions which I receive which is related to MySQL installation. The question is how do I know which version of the MySQL I have installed on my server. Here is the simple trick which works all the time. Connect to your MySQL engine with the help of Command Prompt or MySQL Workbench. When you execute the following command it will give us all the necessary information related to MySQL Version. SHOW VARIABLES LIKE "%version%"; Here is the screenshot of the result which I receive when I ran above command on my Test Server.

  • Switching the layout in Orchard CMS

    - by Bertrand Le Roy
    The UI composition in Orchard is extremely flexible, thanks in no small part to the usage of dynamic Clay shapes. Every notable UI construct in Orchard is built as a shape that other parts of the system can then party on and modify any way they want. Case in point today: modifying the layout (which is a shape) on the fly to provide custom page structures for different parts of the site. This might actually end up being built-in Orchard 1.0 but for the moment it’s not in there. Plus, it’s quite interesting to see how it’s done. We are going to build a little extension that allows for specialized layouts in addition to the default layout.cshtml that Orchard understands out of the box. The extension will add the possibility to add the module name (or, in MVC terms, area name) to the template name, or module and controller names, or module, controller and action names. For example, the home page is served by the HomePage module, so with this extension you’ll be able to add an optional layout-homepage.cshtml file to your theme to specialize the look of the home page while leaving all other pages using the regular layout.cshtml. I decided to implement this sample as a theme with code. This way, the new overrides are only enabled as the theme is activated, which makes a lot of sense as this is going to be where you’ll be creating those additional layouts. The first thing I did was to create my own theme, derived from the default TheThemeMachine with this command: codegen theme CustomLayoutMachine /CreateProject:true /IncludeInSolution:true /BasedOn:TheThemeMachine .csharpcode, .csharpcode pre { font-size: 12px; 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; } Once that was done, I worked around a known bug and moved the new project from the Modules solution folder into Themes (the code was already physically in the right place, this is just about Visual Studio editing). The CreateProject flag in the command-line created a project file for us in the theme’s folder. This is only necessary if you want to run code outside of views from that theme. The code that we want to add is the following LayoutFilter.cs: using System.Linq; using System.Web.Mvc; using System.Web.Routing; using Orchard; using Orchard.Mvc.Filters; namespace CustomLayoutMachine.Filters { public class LayoutFilter : FilterProvider, IResultFilter { private readonly IWorkContextAccessor _wca; public LayoutFilter(IWorkContextAccessor wca) { _wca = wca; } public void OnResultExecuting(ResultExecutingContext filterContext) { var workContext = _wca.GetContext(); var routeValues = filterContext.RouteData.Values; workContext.Layout.Metadata.Alternates.Add( BuildShapeName(routeValues, "area")); workContext.Layout.Metadata.Alternates.Add( BuildShapeName(routeValues, "area", "controller")); workContext.Layout.Metadata.Alternates.Add( BuildShapeName(routeValues, "area", "controller", "action")); } public void OnResultExecuted(ResultExecutedContext filterContext) { } private static string BuildShapeName( RouteValueDictionary values, params string[] names) { return "Layout__" + string.Join("__", names.Select(s => ((string)values[s] ?? "").Replace(".", "_"))); } } } This filter is intercepting ResultExecuting, which is going to provide a context object out of which we can extract the route data. We are also injecting an IWorkContextAccessor dependency that will give us access to the current Layout object, so that we can add alternate shape names to its metadata. We are adding three possible shape names to the default, with different combinations of area, controller and action names. For example, a request to a blog post is going to be routed to the “Orchard.Blogs” module’s “BlogPost” controller’s “Item” action. Our filters will then add the following shape names to the default “Layout”: Layout__Orchard_Blogs Layout__Orchard_Blogs__BlogPost Layout__Orchard_Blogs__BlogPost__Item Those template names get mapped into the following file names by the system (assuming the Razor view engine): Layout-Orchard_Blogs.cshtml Layout-Orchard_Blogs-BlogPost.cshtml Layout-Orchard_Blogs-BlogPost-Item.cshtml This works for any module/controller/action of course, but in the sample I created Layout-HomePage.cshtml (a specific layout for the home page), Layout-Orchard_Blogs.cshtml (a layout for all the blog views) and Layout-Orchard_Blogs-BlogPost-Item.cshtml (a layout that is specific to blog posts). Of course, this is just an example, and this kind of dynamic extension of shapes that you didn’t even create in the first place is highly encouraged in Orchard. You don’t have to do it from a filter, we only did it this way because that was a good place where we could get the context that we needed. And of course, you can base your alternate shape names on something completely different from route values if you want. For example, you might want to create your own part that modifies the layout for a specific content item, or you might want to do it based on the raw URL (like it’s done in widget rules) or who knows what crazy custom rule. The point of all this is to show that extending or modifying shapes is easy, and the layout just happens to be a shape. In other words, you can do whatever you want. Ain’t that nice? The custom theme can be found here: Orchard.Theme.CustomLayoutMachine.1.0.nupkg Many thanks to Louis, who showed me how to do this.

  • QotD: Roger Yeung on Oracle's Java Uninstall Applet

    - by $utils.escapeXML($entry.author)
    We have a build of an Applet that will assist in the removal of older versions of the JRE. The Applet is available for testing on http://java.com/uninstall-tool . At this stage the Applet only targets the Windows platform, as it represents the largest installed base and the need for platform specific elements made Windows the logical starting point. We are deliberately not giving documentation on how to use the applet - we want feedback of the tool standing on its own.The intent of making this build available is to gather feedback; ideas, suggestions, comments, good and bad, what works, what does not work, what could be improved, etc. Please try it out and give us feedback to ensure a smooth release.Roger Yeung in a post with more details on providing feedback.
