• The Evolution Of C#

  - by Paulo Morgado

  The first release of C# (C# 1.0) was all about building a new language for managed code that appealed, mostly, to C++ and Java programmers. The second release (C# 2.0) was mostly about adding what wasn’t time to built into the 1.0 release. The main feature for this release was Generics. The third release (C# 3.0) was all about reducing the impedance mismatch between general purpose programming languages and databases. To achieve this goal, several functional programming features were added to the language and LINQ was born. Going forward, new trends are showing up in the industry and modern programming languages need to be more: Declarative With imperative languages, although having the eye on the what, programs need to focus on the how. This leads to over specification of the solution to the problem in hand, making next to impossible to the execution engine to be smart about the execution of the program and optimize it to run it more efficiently (given the hardware available, for example). Declarative languages, on the other hand, focus only on the what and leave the how to the execution engine. LINQ made C# more declarative by using higher level constructs like orderby and group by that give the execution engine a much better chance of optimizing the execution (by parallelizing it, for example). Concurrent Concurrency is hard and needs to be thought about and it’s very hard to shoehorn it into a programming language. Parallel.For (from the parallel extensions) looks like a parallel for because enough expressiveness has been built into C# 3.0 to allow this without having to commit to specific language syntax. Dynamic There was been lots of debate on which ones are the better programming languages: static or dynamic. The fact is that both have good qualities and users of both types of languages want to have it all. All these trends require a paradigm switch. C# is, in many ways, already a multi-paradigm language. It’s still very object oriented (class oriented as some might say) but it can be argued that C# 3.0 has become a functional programming language because it has all the cornerstones of what a functional programming language needs. Moving forward, will have even more. Besides the influence of these trends, there was a decision of co-evolution of the C# and Visual Basic programming languages. Since its inception, there was been some effort to position C# and Visual Basic against each other and to try to explain what should be done with each language or what kind of programmers use one or the other. Each language should be chosen based on the past experience and familiarity of the developer/team/project/company and not by particular features. In the past, every time a feature was added to one language, the users of the other wanted that feature too. Going forward, when a feature is added to one language, the other will work hard to add the same feature. This doesn’t mean that XML literals will be added to C# (because almost the same can be achieved with LINQ To XML), but Visual Basic will have auto-implemented properties. Most of these features require or are built on top of features of the .NET Framework and, the focus for C# 4.0 was on dynamic programming. Not just dynamic types but being able to talk with anything that isn’t a .NET class. Also introduced in C# 4.0 is co-variance and contra-variance for generic interfaces and delegates. Stay tuned for more on the new C# 4.0 features.

• Guest (and occasional co-host) on Jesse Liberty's Yet Another Podcast

  - by Jon Galloway

  I was a recent guest on Jesse Liberty's Yet Another Podcast talking about the latest Visual Studio, ASP.NET and Azure releases. Download / Listen: Yet Another Podcast #75–Jon Galloway on ASP.NET/ MVC/ Azure Co-hosted shows: Jesse's been inviting me to co-host shows and I told him I'd show up when I was available. It's a nice change to be a drive-by co-host on a show (compared with the work that goes into organizing / editing / typing show notes for Herding Code shows). My main focus is on Herding Code, but it's nice to pop in and talk to Jesse's excellent guests when it works out. Some shows I've co-hosted over the past year: Yet Another Podcast #76–Glenn Block on Node.js & Technology in China Yet Another Podcast  #73 - Adam Kinney on developing for Windows 8 with HTML5 Yet Another Podcast #64 - John Papa & Javascript Yet Another Podcast #60 - Steve Sanderson and John Papa on Knockout.js Yet Another Podcast #54–Damian Edwards on ASP.NET Yet Another Podcast #53–Scott Hanselman on Blogging Yet Another Podcast #52–Peter Torr on Windows Phone Multitasking Yet Another Podcast #51–Shawn Wildermuth: //build, Xaml Programming & Beyond And some more on the way that haven't been released yet. Some of these I'm pretty quiet, on others I get wacky and hassle the guests because, hey, not my podcast so not my problem. Show notes from the ASP.NET / MVC / Azure show: What was just released Visual Studio 2012 Web Developer features ASP.NET 4.5 Web Forms Strongly Typed data controls Data access via command methods Similar Binding syntax to ASP.NET MVC Some context: Damian Edwards and WebFormsMVP Two questions from Jesse: Q: Are you making this harder or more complicated for Web Forms developers? Short answer: Nothing's removed, it's just a new option History of SqlDataSource, ObjectDataSource Q: If I'm using some MVC patterns, why not just move to MVC? Short answer: This works really well in hybrid applications, doesn't require a rewrite Allows sharing models, validation, other code between Web Forms and MVC ASP.NET MVC Adaptive Rendering (oh, also, this is in Web Forms 4.5 as well) Display Modes Mobile project template using jQuery Mobile OAuth login to allow Twitter, Google, Facebook, etc. login Jon (and friends') MVC 4 book on the way: Professional ASP.NET MVC 4 Windows 8 development Jesse and Jon announce they're working on a new book: Pro Windows 8 Development with XAML and C# Jon and Jesse agree that it's nice to be able to write Windows 8 applications using the same skills they picked up for Silverlight, WPF, and Windows Phone development. Compare / contrast ASP.NET MVC and Windows 8 development Q: Does ASP.NET and HTML5 development overlap? Jon thinks they overlap in the MVC world because you're writing HTML views without controls Jon describes how his web development career moved from a preoccupation with server code to a focus on user interaction, which occurs in the browser Jon mentions his NDC Oslo presentation on Learning To Love HTML as Beautiful Code Q: How do you apply C# / XAML or HTML5 skills to Windows 8 development? Q: If I'm a XAML programmer, what's the learning curve on getting up to speed on ASP.NET MVC? Jon describes the difference in application lifecycle and state management Jon says it's nice that web development is really interactive compared to application development Q: Can you learn MVC by reading a book? Or is it a lot bigger than that? What is Azure, and why would I use it? Jon describes the traditional Azure platform mode and how Azure Web Sites fits in Q: Why wouldn't Jesse host his blog on Azure Web Sites? Domain names on Azure Web Sites File hosting options Q: Is Azure just another host? How is it different from any of the other shared hosting options? A: Azure gives you the ability to scale up or down whenever you want A: Other services are available if or when you want them

• How To Delete Built-in Windows 7 Power Plans (and Why You Probably Shouldn’t)

  - by The Geek

  Do you actually use the Windows 7 power management features? If so, have you ever wanted to just delete one of the built-in power plans? Here’s how you can do so, and why you probably should leave it alone. Just in case you’re new to the party, we’re talking about the power plans that you see when you click on the battery/plug icon in the system tray. The problem is that one of the built-in plans always shows up there, even if you only use custom plans. When you go to “More power options” on the menu there, you’ll be taken to a list of them, but you’ll be unable to get rid of any of the built-in ones, even if you have your own. You can actually delete the power plans, but it will probably cause problems, so we highly recommend against it. If you still want to proceed, keep reading. Delete Built-in Power Plans in Windows 7 Open up an Administrator mod command prompt by right-clicking on the command prompt and choosing “Run as Administrator”, then type in the following command, which will show you a whole list of the plans. powercfg list Do you see that really long GUID code in the middle of each listing? That’s what we’re going to need for the next step. To make it easier, we’ll provide the codes here, just in case you don’t know how to copy to the clipboard from the command prompt. Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced) Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c  (High performance)Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a  (Power saver) Before you do any deleting, what you’re going to want to do is export the plan to a file using the –export parameter. For some unknown reason, I used the .xml extension when I did this, though the file isn’t in XML format. Moving on… here’s the syntax of the command: powercfg –export balanced.xml 381b4222-f694-41f0-9685-ff5bb260df2e This will export the Balanced plan to the file balanced.xml. And now, we can delete the plan by using the –delete parameter, and the same GUID.  powercfg –delete 381b4222-f694-41f0-9685-ff5bb260df2e If you want to import the plan again, you can use the -import parameter, though it has one weirdness—you have to specify the full path to the file, like this: powercfg –import c:\balanced.xml Using what you’ve learned, you can export each of the plans to a file, and then delete the ones you want to delete. Why Shouldn’t You Do This? Very simple. Stuff will break. On my test machine, for example, I removed all of the built-in plans, and then imported them all back in, but I’m still getting this error anytime I try to access the panel to choose what the power buttons do: There’s a lot more error messages, but I’m not going to waste your time with all of them. So if you want to delete the plans, do so at your own peril. At least you’ve been warned!

• Creating dynamic breadcrumb in asp.net mvc with mvcsitemap provider

  - by Jalpesh P. Vadgama

  I have done lots breadcrumb kind of things in normal asp.net web forms I was looking for same for asp.net mvc. After searching on internet I have found one great nuget package for mvpsite map provider which can be easily implemented via site map provider. So let’s check how its works. I have create a new MVC 3 web application called breadcrumb and now I am adding a reference of site map provider via nuget package like following. You can find more information about MVC sitemap provider on following URL. https://github.com/maartenba/MvcSiteMapProvid So once you add site map provider. You will find a Mvc.SiteMap file like following. And following is content of that file. <?xml version="1.0" encoding="utf-8" ?> <mvcSiteMap xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-3.0" xsi:schemaLocation="http://mvcsitemap.codeplex.com/schemas/MvcSiteMap-File-3.0 MvcSiteMapSchema.xsd" enableLocalization="true"> <mvcSiteMapNode title="Home" controller="Home" action="Index"> <mvcSiteMapNode title="About" controller="Home" action="About"/> </mvcSiteMapNode> </mvcSiteMap> So now we have added site map so now its time to make breadcrumb dynamic. So as we all know that with in the standard asp.net mvc template we have action link by default for Home and About like following. <div id="menucontainer"> <ul id="menu"> <li>@Html.ActionLink("Home", "Index", "Home")</li> <li>@Html.ActionLink("About", "About", "Home")</li> </ul> </div> Now I want to replace that with our sitemap provider and make it dynamic so I have added the following code. <div id="menucontainer"> @Html.MvcSiteMap().Menu(true) </div> That’s it. This is the magic code @Html.MvcSiteMap will dynamically create breadcrumb for you. Now let’s run this in browser. You can see that it has created breadcrumb dynamically without writing any action link code. So here you can see with MvcSiteMap provider we don’t have to write any code we just need to add menu syntax and rest it will do automatically. That’s it. Hope you liked it. Stay tuned for more till then happy programming.

• SQL SERVER – Solution of Puzzle – Swap Value of Column Without Case Statement

  - by pinaldave

  Earlier this week I asked a question where I asked how to Swap Values of the column without using CASE Statement. Read here: SQL SERVER – A Puzzle – Swap Value of Column Without Case Statement. I have proposed 3 different solutions in the blog posts itself. I had requested the help of the community to come up with alternate solutions and honestly I am stunned and amazed by the qualified entries. I will be not able to cover every single solution which is posted as a comment, however, I would like to for sure cover few interesting entries. However, I am selecting 5 solutions which are different (not necessary they are most optimal or best – just different and interesting). Just for clarity I am involving the original problem statement here. USE tempdb GO CREATE TABLE SimpleTable (ID INT, Gender VARCHAR(10)) GO INSERT INTO SimpleTable (ID, Gender) SELECT 1, 'female' UNION ALL SELECT 2, 'male' UNION ALL SELECT 3, 'male' GO SELECT * FROM SimpleTable GO -- Insert Your Solutions here -- Swap value of Column Gender SELECT * FROM SimpleTable GO DROP TABLE SimpleTable GO Here are the five most interesting and different solutions I have received. Solution by Roji P Thomas UPDATE S SET S.Gender = D.Gender FROM SimpleTable S INNER JOIN SimpleTable D ON S.Gender != D.Gender I really loved the solutions as it is very simple and drives the point home – elegant and will work pretty much for any values (not necessarily restricted by the option in original question ‘male’ or ‘female’). Solution by Aneel CREATE TABLE #temp(id INT, datacolumn CHAR(4)) INSERT INTO #temp VALUES(1,'gent'),(2,'lady'),(3,'lady') DECLARE @value1 CHAR(4), @value2 CHAR(4) SET @value1 = 'lady' SET @value2 = 'gent' UPDATE #temp SET datacolumn = REPLACE(@value1 + @value2,datacolumn,'') Aneel has very interesting solution where he combined both the values and replace the original value. I personally liked this creativity of the solution. Solution by SIJIN KUMAR V P UPDATE SimpleTable SET Gender = RIGHT(('fe'+Gender), DIFFERENCE((Gender),SOUNDEX(Gender))*2) Sijin has amazed me with Difference and Soundex function. I have never visualized that above two functions can resolve the problem. Hats off to you Sijin. Solution by Nikhildas UPDATE St SET St.Gender = t.Gender FROM SimpleTable St CROSS Apply (SELECT DISTINCT gender FROM SimpleTable WHERE St.Gender != Gender) t I was expecting that someone will come up with this solution where they use CROSS APPLY. This is indeed very neat and for sure interesting exercise. If you do not know how CROSS APPLY works this is the time to learn. Solution by mistermagooo UPDATE SimpleTable SET Gender=X.NewGender FROM (VALUES('male','female'),('female','male')) AS X(OldGender,NewGender) WHERE SimpleTable.Gender=X.OldGender As per author this is a slow solution but I love how syntaxes are placed and used here. I love how he used syntax here. I will say this is the most beautifully written solution (not necessarily it is best). Bonus: Solution by Madhivanan Somehow I was confident Madhi – SQL Server MVP will come up with something which I will be compelled to read. He has written a complete blog post on this subject and I encourage all of you to go ahead and read it. Now personally I wanted to list every single comment here. There are some so good that I am just amazed with the creativity. I will write a part of this blog post in future. However, here is the challenge for you. Challenge: Go over 50+ various solutions listed to the simple problem here. Here are my two asks for you. 1) Pick your best solution and list here in the comment. This exercise will for sure teach us one or two things. 2) Write your own solution which is yet not covered already listed 50 solutions. I am confident that there is no end to creativity.

• Using progress dialog in Visual Studio extensions

  - by Utkarsh Shigihalli

  Originally posted on: http://geekswithblogs.net/onlyutkarsh/archive/2014/05/23/using-progress-dialog-in-visual-studio-extensions.aspxAs a Visual Studio extension developer you are required to keep the aesthetics of Visual Studio in tact when you integrate your extension with Visual Studio. Your extension looks odd when you try to use windows controls and dialogs in your extensions. Visual Studio SDK exposes many interfaces so that your extension looks as integrated with Visual Studio as possible. When your extension is performing a long running task, you have many options to notify the progress to the user. One such option is through Visual Studio status bar. I have previously blogged about displaying progress through Visual Studio status bar. In this blog post I am going to highlight another way using IVsThreadedWaitDialog2 interface. One thing to note is, as the IVsThreadedWaitDialog2 interface name suggests it is a dialog hence user cannot perform any action when the dialog is being shown. So Visual Studio seems responsive to user, even when a task is being performed. Visual Studio itself makes use of this interface heavily. One example is when you are loading a solution (.sln) with lot of projects Visual Studio displays dialog implemented by this interface (screenshot below). So the first step is to get the instance of IVsThreadedWaitDialog2 interface using IServiceProvider interface. var dialogFactory = _serviceProvider.GetService(typeof(SVsThreadedWaitDialogFactory)) as IVsThreadedWaitDialogFactory; IVsThreadedWaitDialog2 dialog = null; if (dialogFactory != null) { dialogFactory.CreateInstance(out dialog); } So if your have the package initialized properly out object dialog will be not null and would contain the instance of IVsThreadedWaitDialog2 interface. Once the instance is got, you call the different methods to manage the dialog. I will cover 3 methods StartWaitDialog, EndWaitDialog and HasCanceled in this blog post. You show the progress dialog as below. if (dialog != null && dialog.StartWaitDialog( "Threaded Wait Dialog", "VS is Busy", "Progress text", null, "Waiting status bar text", 0, false, true) == VSConstants.S_OK) { Thread.Sleep(4000); } As you can see from the method syntax it is very similar to standard windows message box. If you pass true to the 7th parameter to StartWaitDialog method, you will also see a cancel button allowing user to cancel the running task. You can react when user cancels the task as below. bool isCancelled; dialog.HasCanceled(out isCancelled); if (isCancelled) { MessageBox.Show("Cancelled"); } Finally, you can close the dialog when you complete the task running as below. int usercancel; dialog.EndWaitDialog(out usercancel); To help you quickly experience the above code, I have created a sample. It is available for download from GitHub. The sample creates a tool window with two buttons to demo the above explained scenarios. The tool window can be accessed by clicking View –> Other Windows -> ProgressDialogDemo Window

• Mirroring git and mercurial repos the lazy way

  - by Greg Malcolm

  I maintain Python Koans on mirrored on both Github using git and Bitbucket using mercurial. I get pull requests from both repos but it turns out keeping the two repos in sync is pretty easy. Here is how it's done... Assuming I’m starting again on a clean laptop, first I clone both repos ~/git $ hg clone https://bitbucket.org/gregmalcolm/python_koans ~/git $ git clone [email protected]:gregmalcolm/python_koans.git python_koans2 The only thing that makes a folder a git or mercurial repository is the .hg folder in the root of python_koans and the .git folder in the root of python_koans2. So I just need to move the .git folder over into the python_koans folder I'm using for mercurial: ~/git $ rm -rf python_koans/.git ~/git $ mv python_koans2/.git python_koans ~/git $ ls -la python_koans total 48 drwxr-xr-x 11 greg staff 374 Mar 17 15:10 . drwxr-xr-x 62 greg staff 2108 Mar 17 14:58 .. drwxr-xr-x 12 greg staff 408 Mar 17 14:58 .git -rw-r--r-- 1 greg staff 34 Mar 17 14:54 .gitignore drwxr-xr-x 13 greg staff 442 Mar 17 14:54 .hg -rw-r--r-- 1 greg staff 48 Mar 17 14:54 .hgignore -rw-r--r-- 1 greg staff 365 Mar 17 14:54 Contributor Notes.txt -rw-r--r-- 1 greg staff 1082 Mar 17 14:54 MIT-LICENSE -rw-r--r-- 1 greg staff 5765 Mar 17 14:54 README.txt drwxr-xr-x 10 greg staff 340 Mar 17 14:54 python 2 drwxr-xr-x 10 greg staff 340 Mar 17 14:54 python 3 That’s about it! Now git and mercurial are tracking files in the same folder. Of course you will still need to set up your .gitignore to ignore mercurial’s dotfiles and .hgignore to ignore git’s dotfiles or there will be squabbling in the backseat. ~/git $ cd python_koans/ ~/git/python_koans $ cat .gitignore *.pyc *.swp .DS_Store answers .hg <-- Ignore mercurial ~/git/python_koans $ cat .hgignore syntax: glob *.pyc *.swp .DS_Store answers .git <-- Ignore git Because both my mirrors are both identical as far as tracked files are concerned I won’t yet see anything if I check statuses at this point: ~/git/python_koans $ git status # On branch master nothing to commit (working directory clean) ~/git/python_koans $ hg status ~/git/python_koans But how about if I accept a pull request from the bitbucket (mercuial) site? ~/git/python_koans $ hg status ~/git/python_koans $ git status # On branch master # Your branch is behind 'origin/master' by 1 commit, and can be fast-forwarded. # # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: python 2/koans/about_decorating_with_classes.py # modified: python 2/koans/about_iteration.py # modified: python 2/koans/about_with_statements.py # modified: python 3/koans/about_decorating_with_classes.py # modified: python 3/koans/about_iteration.py # modified: python 3/koans/about_with_statements.py Mercurial doesn’t have any changes to track right now, but git has changes. Commit and push them up to github and balance is restored to the force: ~/git/python_koans $ git commit -am "Merge from bitbucket mirror: 'gpiancastelli - Fix for issue #21 and some other tweaks'" [master 79ca184] Merge from bitbucket mirror: 'gpiancastelli - Fix for issue #21 and some other tweaks' 6 files changed, 78 insertions(+), 63 deletions(-) ~/git/python_koans $ git push origin master Or just use hg-git? The github developers have actually published a plugin for automatic mirroring: http://hg-git.github.com I haven’t used it because at the time I tried it a couple of years ago I was having problems getting all the parts to play nice with each other. Probably works fine now though..

• How the "migrations" approach makes database continuous integration possible

  - by David Atkinson

  Testing a database upgrade script as part of a continuous integration process will only work if there is an easy way to automate the generation of the upgrade scripts. There are two common approaches to managing upgrade scripts. The first is to maintain a set of scripts as-you-go-along. Many SQL developers I've encountered will store these in a folder prefixed numerically to ensure they are ordered as they are intended to be run. Occasionally there is an accompanying document or a batch file that ensures that the scripts are run in the defined order. Writing these scripts during the course of development requires discipline. It's all too easy to load up the table designer and to make a change directly to the development database, rather than to save off the ALTER statement that is required when the same change is made to production. This discipline can add considerable overhead to the development process. However, come the end of the project, everything is ready for final testing and deployment. The second development paradigm is to not do the above. Changes are made to the development database without considering the incremental update scripts required to effect the changes. At the end of the project, the SQL developer or DBA, is tasked to work out what changes have been made, and to hand-craft the upgrade scripts retrospectively. The end of the project is the wrong time to be doing this, as the pressure is mounting to ship the product. And where data deployment is involved, it is prudent not to feel rushed. Schema comparison tools such as SQL Compare have made this latter technique more bearable. These tools work by analyzing the before and after states of a database schema, and calculating the SQL required to transition the database. Problem solved? Not entirely. Schema comparison tools are huge time savers, but they have their limitations. There are certain changes that can be made to a database that can't be determined purely from observing the static schema states. If a column is split, how do we determine the algorithm required to copy the data into the new columns? If a NOT NULL column is added without a default, how do we populate the new field for existing records in the target? If we rename a table, how do we know we've done a rename, as we could equally have dropped a table and created a new one? All the above are examples of situations where developer intent is required to supplement the script generation engine. SQL Source Control 3 and SQL Compare 10 introduced a new feature, migration scripts, allowing developers to add custom scripts to replace the default script generation behavior. These scripts are committed to source control alongside the schema changes, and are associated with one or more changesets. Before this capability was introduced, any schema change that required additional developer intent would break any attempt at auto-generation of the upgrade script, rendering deployment testing as part of continuous integration useless. SQL Compare will now generate upgrade scripts not only using its diffing engine, but also using the knowledge supplied by developers in the guise of migration scripts. In future posts I will describe the necessary command line syntax to leverage this feature as part of an automated build process such as continuous integration.

• Integrating JavaFX Scene Builder in the IDEs

  - by Jerome Cambon

  I experienced recently using Scene Builder from Netbeans, Eclipse and IntelliJ IDEA. As you may know, Scene Builder is a standalone tool, that can be used independently of any IDE. But it can be very convenient to use it with your favorite IDE, for instance start it by double-clicking on an FXML file, or run samples delivered with Scene Builder.  I'm sharing here with you few tweaks that I had to do for a better integration. Scene Builder 1.1 Developer Preview should be installed before doing the tweaks. The steps below have been done on Windows 7. It should be very similar on both Mac OS and Linux. Please tell me if you find any issue on one of these 2 platforms. Netbeans 7.3 Netbeans 7.3 can be downloaded from here. Creating a New FXML project Part of the JavaFx projects, Netbeans allows to create a 'JavaFX FXML Application', that creates a JavaFx project based on FXML description. The FXML file will be editable with Scene Builder. Starting Scene Builder from Netbeans If SceneBuilder 1.1 is installed, Netbeans will discover it automatically.In case of issue, one can open the Options panel, Java section, JavaFx tab. Scene Builder home should appear here. You can then either Open the FXML file with Scene Builder, or edit it with the Netbeans FXML editor : When 'Open' is selected, Scene Builder appears on top of the Netbeans window : When 'Edit' is selected, the FXML is opened in the Netbeans FXML editor, which support syntax highlighting and completion : Using Scene Builder Samples Scene Builder provides Netbeans projects, that can be opened/run directly : Eclipse 4.2.1 + e(fx)clipse 0.1.1 JavaFX integration in Eclipse has been done with the e(fx)clipse plugin. A distribution bundle containing Eclipse and e(fx)clipse is provided here. Creating New FXML project All the JavaFX-related projects can be found in 'Other' section : First create a new JavaFX project: Enter the project name (Test here). JavaFX delivery will be found in the JRE. Then, create a 'New FXML Document': Enter the FXML file name (Sample here). You may also want to choose the FXML document root element (AnchorPane by default). Dynamic root is for advanced users which want to manage custom types. Starting Scene Builder from Eclipse Once created, you can then either Open the FXML file with Scene Builder, or Open it in the Eclipse FXML editor : Using Scene Builder Samples from Eclipse To use Scene Builder samples, first create a new JavaFX Project (from 'Other' section): Then, on the next panel, 'Link additionnal source': … and select the source directory of a Scene Builder example : HelloWorld here (the parent directory of the java package should be selected).Then, choose a 'Folder name' for your sample: You can now run the Scene Builder example by right-clicking the Main.java source file: IntelliJ IDEA 11.1.3 IntelliJ IDEA Community Edition can be downloaded from here. IntelliJ IDEA has no specific JavaFX integration. Creating New IntelliJ project from existing source Since IntelliJ has no JavaFX project knowledge, we are using the Scene Builder samples as a starting point. We are going to create a new Java project from the HelloWorld sample: Then, click twice on 'Next' (nothing to change), then 'Finish'. The 'HelloWorld' project is created. Starting Scene Builder from IntelliJ We need to tell the IDE that FXML files are opened with an external application. Then, the OS file association will be used. To do this, open the File->Settings panel. Then, select 'File Types' and 'Files opened in associated applications'. And add a new wildcard : '*.fxml' : Now, from the HelloWorld project, you can double-click on HelloWorld.fxml : Scene Builder window appears on top of the IntelliJ window : Using Scene Builder Samples from IntelliJ We need to tell IntelliJ that the fxml files must be copied in the build directory.To do that, from the HelloWorld directory, open the 'idea' section, and edit the 'compiler.xml' file. We need to add an '*.fxml' entry: Then, you can run the sample from HelloWorld project, by right-clicking the Main class:

• Skewed: a rotating camera in a simple CPU-based voxel raycaster/raytracer

  - by voxelizr

  TL;DR -- in my first simple software voxel raycaster, I cannot get camera rotations to work, seemingly correct matrices notwithstanding. The result is skewed: like a flat rendering, correctly rotated, however distorted and without depth. (While axis-aligned ie. unrotated, depth and parallax are as expected.) I'm trying to write a simple voxel raycaster as a learning exercise. This is purely CPU based for now until I figure out how things work exactly -- fow now, OpenGL is just (ab)used to blit the generated bitmap to the screen as often as possible. Now I have gotten to the point where a perspective-projection camera can move through the world and I can render (mostly, minus some artifacts that need investigation) perspective-correct 3-dimensional views of the "world", which is basically empty but contains a voxel cube of the Stanford Bunny. So I have a camera that I can move up and down, strafe left and right and "walk forward/backward" -- all axis-aligned so far, no camera rotations. Herein lies my problem. Screenshot #1: correct depth when the camera is still strictly axis-aligned, ie. un-rotated. Now I have for a few days been trying to get rotation to work. The basic logic and theory behind matrices and 3D rotations, in theory, is very clear to me. Yet I have only ever achieved a "2.5 rendering" when the camera rotates... fish-eyey, bit like in Google Streetview: even though I have a volumetric world representation, it seems --no matter what I try-- like I would first create a rendering from the "front view", then rotate that flat rendering according to camera rotation. Needless to say, I'm by now aware that rotating rays is not particularly necessary and error-prone. Still, in my most recent setup, with the most simplified raycast ray-position-and-direction algorithm possible, my rotation still produces the same fish-eyey flat-render-rotated style looks: Screenshot #2: camera "rotated to the right by 39 degrees" -- note how the blue-shaded left-hand side of the cube from screen #2 is not visible in this rotation, yet by now "it really should"! Now of course I'm aware of this: in a simple axis-aligned-no-rotation-setup like I had in the beginning, the ray simply traverses in small steps the positive z-direction, diverging to the left or right and top or bottom only depending on pixel position and projection matrix. As I "rotate the camera to the right or left" -- ie I rotate it around the Y-axis -- those very steps should be simply transformed by the proper rotation matrix, right? So for forward-traversal the Z-step gets a bit smaller the more the cam rotates, offset by an "increase" in the X-step. Yet for the pixel-position-based horizontal+vertical-divergence, increasing fractions of the x-step need to be "added" to the z-step. Somehow, none of my many matrices that I experimented with, nor my experiments with matrix-less hardcoded verbose sin/cos calculations really get this part right. Here's my basic per-ray pre-traversal algorithm -- syntax in Go, but take it as pseudocode: fx and fy: pixel positions x and y rayPos: vec3 for the ray starting position in world-space (calculated as below) rayDir: vec3 for the xyz-steps to be added to rayPos in each step during ray traversal rayStep: a temporary vec3 camPos: vec3 for the camera position in world space camRad: vec3 for camera rotation in radians pmat: typical perspective projection matrix The algorithm / pseudocode: // 1: rayPos is for now "this pixel, as a vector on the view plane in 3d, at The Origin" rayPos.X, rayPos.Y, rayPos.Z = ((fx / width) - 0.5), ((fy / height) - 0.5), 0 // 2: rotate around Y axis depending on cam rotation. No prob since view plane still at Origin 0,0,0 rayPos.MultMat(num.NewDmat4RotationY(camRad.Y)) // 3: a temp vec3. planeDist is -0.15 or some such -- fov-based dist of view plane from eye and also the non-normalized, "in axis-aligned world" traversal step size "forward into the screen" rayStep.X, rayStep.Y, rayStep.Z = 0, 0, planeDist // 4: rotate this too -- 0,zstep should become some meaningful xzstep,xzstep rayStep.MultMat(num.NewDmat4RotationY(CamRad.Y)) // set up direction vector from still-origin-based-ray-position-off-rotated-view-plane plus rotated-zstep-vector rayDir.X, rayDir.Y, rayDir.Z = -rayPos.X - me.rayStep.X, -rayPos.Y, rayPos.Z + rayStep.Z // perspective projection rayDir.Normalize() rayDir.MultMat(pmat) // before traversal, the ray starting position has to be transformed from origin-relative to campos-relative rayPos.Add(camPos) I'm skipping the traversal and sampling parts -- as per screens #1 through #3, those are "basically mostly correct" (though not pretty) -- when axis-aligned / unrotated.

• 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.

• LINQ to Twitter Queries with LINQPad

  - by Joe Mayo

  LINQPad is a popular utility for .NET developers who use LINQ a lot.  In addition to standard SQL queries, LINQPad also supports other types of LINQ providers, including LINQ to Twitter.  The following sections explain how to set up LINQPad for making queries with LINQ to Twitter. LINQPad comes in a couple versions and this example uses LINQPad4, which runs on the .NET Framework 4.0. 1. The first thing you'll need to do is set up a reference to the LinqToTwitter.dll. From the Query menu, select query properties. Click the Browse button and find the LinqToTwitter.dll binary. You should see something similar to the Query Properties window below. 2. While you have the query properties window open, add the namespace for the LINQ to Twitter types.  Click the Additional Namespace Imports tab and type in LinqToTwitter. The results are shown below: 3. The default query type, when you first start LINQPad, is C# Expression, but you'll need to change this to support multiple statements.  Change the Language dropdown, on the Main window, to C# Statements. 4. To query LINQ to Twitter, instantiate a TwitterContext, by typing the following into the LINQPad Query window: var ctx = new TwitterContext(); Note: If you're getting syntax errors, go back and make sure you did steps #2 and #3 properly. 5. Next, add a query, but don't materialize it, like this: var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; 6. Next, you want the output to be displayed in the LINQPad grid, so do a Dump, like this: tweets.Dump(); The following image shows the final results:   That was an unauthenticated query, but you can also perform authenticated queries with LINQ to Twitter's support of OAuth.  Here's an example that uses the PinAuthorizer (type this into the LINQPad Query window): var auth = new PinAuthorizer { Credentials = new InMemoryCredentials { ConsumerKey = "", ConsumerSecret = "" }, UseCompression = true, GoToTwitterAuthorization = pageLink => Process.Start(pageLink), GetPin = () => { // this executes after user authorizes, which begins with the call to auth.Authorize() below. Console.WriteLine("\nAfter you authorize this application, Twitter will give you a 7-digit PIN Number.\n"); Console.Write("Enter the PIN number here: "); return Console.ReadLine(); } }; // start the authorization process (launches Twitter authorization page). auth.Authorize(); var ctx = new TwitterContext(auth, "https://api.twitter.com/1/", "https://search.twitter.com/"); var tweets = from tweet in ctx.Status where tweet.Type == StatusType.Public select new { tweet.Text, tweet.Geo, tweet.User }; tweets.Dump(); This code is very similar to what you'll find in the LINQ to Twitter downloadable source code solution, in the LinqToTwitterDemo project.  For obvious reasons, I changed the value assigned to ConsumerKey and ConsumerSecret, which you'll have to obtain by visiting http://dev.twitter.com and registering your application. One tip, you'll probably want to make this easier on yourself by creating your own DLL that encapsulates all of the OAuth logic and then call a method or property on you custom class that returns a fully functioning TwitterContext.  This will help avoid adding all this code every time you want to make a query. Now, you know how to set up LINQPad for LINQ to Twitter, perform unauthenticated queries, and perform queries with OAuth. Joe

• Developer Profile: Marcelo Quinta

  - by Tori Wieldt

  As the Java developer community lead for Oracle, the best part of my job is going to conferences and meeting Java developers. I’ve had the pleasure to meet men and women who are smart, fun and passionate about Java—they make the Java community happen. The current issue of Java Magazine provides profiles of other young Java developers around the world. Subscribe to read them! Marcelo Quinta Age: 24Occupation: Professor, Federal University of GoiasLocation: Goias, Brazil Twitter: @mrquinta Marcelo (white polo shirt, center) and class OTN: When did you realize that you were good at programming? When I was in graduate school, I developed a Java system that displayed worked out the logics of getting the maximum coverage using the fewest resources (for example, the minimum number of soldiers [and positions] needed for a battlefield. It may seems not difficult, but it's a hard problem to solve, mathematically. Here I was, a freshman, who came up with an app  "solving" it. Some Master's students use my software today. It was then I began to believe in what I could do.OTN: What most inspires you about programming?I'm really inspired by the challenges and tension that comes from solving a complicated problems. Lately, I've been doing a new system focused on education and digital inclusion and was very gratifying to see it working and the results. I felt useful for the community. OTN: What are some things you would like to accomplish using Java?Java is a very strong platform and that gives us power to develop applications for different devices and purposes, from home automation with little microcontrollers to systems in big servers. I would like to build more systems that integrate the people life or different business contexts, from PCs to cell phones and tablets, ubiquitously. I think IT has reached a level where the current challenge is to make systems that leverage existing technologies that are present in daily life. Java gives us a very interesting set of options to put it into practice, especially in systems that require more strength.OTN: What technical insights into Java technology have been most important to you?I have really enjoyed the way that Java has evolved with Oracle, with new features added, many of them which were suggested by the community. Java 7 came with substantial improvements in the language syntax and it seems that Java 8 takes it even further. I also made some applications in JavaFX and liked the new version. The Java GUI is on a higher level than is offered out there. I saw some JavaFX prototypes running in modern tablets and I got excited. OTN: What would you like to be doing 10 years from now?I want my work to make a difference for individuals or an institution. It would be interesting to be improving one of the systems that I am making today. Recently I've been mixing my hobbies and work, playing with Arduino and home automation. The JHome project, winner of the Duke's Choice Award in 2011, is very interesting to me.OTN: Do you listen to music when you write code? If so, what kind?Absolutely! I usually listen to electronic music (Prodigy, Fatboy Slim and Paul Oakenfold), rock (Metallica, Strokes, The Black Keys) and a bit of local alternative music. I live in Goiânia, "The Brazilian Seattle" and I profit from it very well. OTN: What do you do when you're not programming?I like to play guitar and to fish. Last year I sold my economy car and bought a old jeep. Some people called me crazy, but since then I've been having a great time and having adventures on the backroads of Brazil. Once I broke my glasses in a funny game involving my car's suspension and the airbags. OTN: Does your girlfriend think you are crazy?Crazy is someone who doesn't have courage to do strange things! My girlfriend likes my style. =D Subscribe to the free Java Magazine to read profiles of other young Java developers. Visit the Java channel on YouTube to see a video of Marcelo in action.

• A tiny Utility to recycle an IIS Application Pool

  - by Rick Strahl

  In the last few weeks I've annoyingly been having problems with an area on my Web site. It's basically ancient articles that are using ASP classic pages and for reasons unknown ASP classic locks up on these pages frequently. It's not an individual page, but ALL ASP classic pages lock up. Ah yes, gotta old tech gone bad. It's not super critical since the content is really old, but still a hassle since it's linked content that still gets quite a bit of traffic. When it happens all ASP classic in that AppPool dies. I've been having a hard time tracking this one down - I suspect an errant COM object I have a Web Monitor running on the server that's checking for failures and while the monitor can detect the failures when the timeouts occur, I didn't have a good way to just restart that particular application pool. I started putzing around with PowerShell, but - as so often seems the case - I can never get the PowerShell syntax right - I just don't use it enough and have to dig out cheat sheets etc. In any case, after about 20 minutes of that I decided to just create a small .NET Console Application that does the trick instead, and in a few minutes I had this:using System; using System.Collections.Generic; using System.Text; using System.DirectoryServices; namespace RecycleApplicationPool { class Program { static void Main(string[] args) { string appPoolName = "DefaultAppPool"; string machineName = "LOCALHOST"; if (args.Length > 0) appPoolName = args[0]; if (args.Length > 1) machineName = args[1]; string error = null; DirectoryEntry root = null; try { Console.WriteLine("Restarting Application Pool " + appPoolName + " on " + machineName + "..."); root = new DirectoryEntry("IIS://" + machineName + "/W3SVC/AppPools/" +appPoolName); Console.WriteLine(root.InvokeGet("Name")); root.Invoke("Recycle"); Console.WriteLine("Application Pool recycling complete..."); } catch(Exception ex) { error = "Error: Unable to access AppPool: " + ex.Message; } if ( !string.IsNullOrEmpty(error) ) { Console.WriteLine(error); return; } } } } To run in you basically provide the name of the ApplicationPool and optionally a machine name if it's not on the local box. RecyleApplicationPool.exe "WestWindArticles" And off it goes. What's nice about AppPool recycling versus doing a full IISRESET is that it only affects the AppPool, and more importantly AppPool recycles happen in a staggered fashion - the existing instance isn't shut down immediately until requests finish while a new instance is fired up to handle new requests. So, now I can easily plug this Executable into my West Wind Web Monitor as an action to take when the site is not responding or timing out which is a big improvement than hanging for an unspecified amount of time. I'm posting this fairly trivial bit of code just in case somebody (maybe myself a few months down the road) is searching for ApplicationPool recyling code. It's clearly trivial, but I've written batch files for this a bunch of times before and actually having a small utility around without having to worry whether Powershell is installed and configured right is actually an improvement. Next time I think about using PowerShell remind me that it's just easier to just build a small .NET Console app, 'k? :-) Resources Download Executable and VS Project© Rick Strahl, West Wind Technologies, 2005-2012Posted in IIS7  .NET  Windows   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• NetBeans PHP Community Council

  - by Tomas Mysik

  Hi all, today we would like to inform all of you that now you have a chance to improve NetBeans via NetBeans PHP Community Council. The author of this activity is Timur Poperecinii and he would like to tell you a few words about it. Hello passionate technical people, First of all let me introduce myself: my name is Timur, I’m a developer from Moldova (that little country between Romania and Ukraine), I develop mostly in .NET and JQuery, but I love to learn more, not being an expert I am familiar with Java (Struts2, Play), PHP (Symfony2), Ruby (Rails), Sencha Touch 2 and other technologies. I was “introduced” in PHP recently by a client of mine who requested to make the work specifically in PHP. Let me tell you a little story about my experience with open source and IDEs: when I was studying in university in 2007 I think, I did a simple little application in PHP and thought “Damn, if only there was a good IDE for PHP so I could relax and no having to remember all the function names”, then when I searched on internet pretty much everyone was using Vim or Emacs on Linux, but it had no autocomplete anyway, just syntax highlighting. I remember using some tool like Notepad++ I think. Nowadays everything changed, we have highlighting and autocomplete for about all standard things in PHP in many IDEs. I use NetBeans for PHP, and I really am happy with the experience I have there with standard PHP code, but for frameworks I still think there is lots of room for improvements. For example we have some Symfony 2 and Twig support. But I’d love to see more of that coming, for example I’m a big fan of file templates, where the main goal is to not waste time on writing over and over again something that can be generated, and it counts even more when you don’t have a lot of autocomplete. So what I thought, “Hey I know Java a little, and NetBeans has plugins, so may be it worth trying to do a file templates plugin”, and so I did, you can find details about my Unified Udevi Symfony2 Plugin for NetBeans 7.2 on my blog. It wasn’t hard, and it even was fun! Give back to open source Now think a little, NetBeans is an open source project and PHP support is just a part of it, so the resources are pretty limited in this area. But we as a community that uses this product, want to have the best possible experience with PHP and frameworks(!!!). So why don’t we GIVE BACK TO OPENSOURCE ? Imagine an IDE that can do all the things you wanted + it is free. Now how far is NetBeans from that point? I guess not so far – you might miss a little niche thing that you use on a daily basis, but then the question appears why don’t you make it happen on your own? NetBeans PHP Community Council What I proposed is to create a NetBeans PHP Community Council that will be formed of people willing to change something, willing to create plugins for their own needs and for the needs of the community, test the plugins created by them too, and basically evolve NetBeans in direction they want to reach. I already talked with the NetBeans PHP team. They are only happy to help this Council, with technical advises, opening some APIs we might need to have access to, and other things. One important thing to mention is that this Council is a Community project, so though we’ll have direct discussions with NetBeans PHP Dev team, NetBeans is not the leading force here, it is the community. You can see more details about the goals and structure I proposed at NetBeans PHP Community Council wiki page. We use this mail list: [email protected] for discussions and topics related to the Council. How can I join To join the NetBeans PHP Community Council please send an email to [email protected] with the subject of the mail starting with [Council New Member]. You can subscribe to this mail list here:http://netbeans.org/projects/php/lists. in your mail please indicate your location, age and experience both in Java and PHP. I need these data to assign you to a team. A response will be send to you with your next assignment and some people to contact. I really hope that you’ll make a step forward and try to make your everyday use of NetBeans even more fun.

• Where to start with game development?

  - by steven_desu

  I asked this earlier in this thread at stackoverflow.com. One of the early comments redirected me here to gamedev.stackexchange.com, so I'm reposting here. Searching for related questions I found a number of very specific questions, but I'm afraid the specifics have proved fruitless for me and after 4 hours on Google I'm no closer than I started, so I felt reaching out to a community might be in order. First, my goal: I've never made a game before, although I've muddled over the possibility several times. I decided to finally sit down and start learning how to code games, use game engines, etc. All so that one day (hopefully soon) I'll be able to make functional (albeit simple) games. I can start adding complexity later, for now I'd be glad to have a keyboard-controlled camera moving in a 3D world with no interaction beyond that. My background: I've worked in SEVERAL programming languages ranging from PHP to C++ to Java to ASM. I'm not afraid of any challenges that come with learning the new syntax or limitations inherent in a new language. All of my past programming experience, however, has been strictly non-graphical and usually with little or extremely simple interaction during execution. I've created extensive and brilliant algorithms for solving logical and mathematical problems as well as graphing problems. However in every case input was either defined in a file, passed form an HTML form, or typed into the console. Real-time interaction with the user is something with which I have no experience. My question: Where should I start in trying to make games? Better yet- where should I start in trying to create a keyboard-navigable 3D environment? In searching online I've found several resources linking to game engines, graphics engines, and physics engines. Here's a brief summary of my experiences with a few engines I tried: Unreal SDK: The tutorial videos assume that you already have in-depth knowledge of 3D modeling, graphics engines, animations, etc. The "Getting Started" page offers no formal explanation of game development but jumps into how Unreal can streamline processes it assumes you're already familiar with. After downloading the SDK and launching it to see if the tools were as intuitive as they claimed, I was greeted with about 60 buttons and a blank void for my 3D modeling. Clicking on "add volume" (to attempt to add a basic cube) I was met with a menu of 30 options. Panicking, I closed the editor. Crystal Space: The website seemed rather informative, explaining that Crystal Space was just for graphics and the companion software, CEL, provided entity logic for making games. A demo game was provided, which was built using "CELStart", their simple tool for people with no knowledge of game programming. I launched the game to see what I might look forward to creating. It froze several times, the menus were buggy, there were thousands of graphical glitches, enemies didn't respond to damage, and when I closed the game it locked up. Gave up on that engine. IrrLicht: The tutorial assumes I have Visual Studio 6.0 (I have Visual Studio 2010). Following their instructions I was unable to properly import the library into Visual Studio and unable to call any of the functions that they kept using. Manually copying header files, class files, and DLLs into my project's folder - the project failed to properly compile. Clearly I'm not off to a good start and I'm going in circles. Can someone point me in the right direction? Should I start by downloading a program like Blender and learning 3D modeling, or should I be learning how to use a graphics engine? Should I look for an all-inclusive game engine, or is it better to try and code my own game logic? If anyone has actually made their own games, I would prefer to hear how they got their start. Also- taking classes at my school is not an option. Nothing is offered.

Should I look for an all-inclusive game engine, or is it better to try and code my own game logic? If anyone has actually made their own games, I would prefer to hear how they got their start. Also- taking classes at my school is not an option. Nothing is offered.

• SharePoint 2013 Developer Ramp-Up - Part 1

  Today I had a little spare time during the morning hours and I decided that after checking MVA that I'm going to query the available course material over at Pluralsight. Wow, thanks to fantastic corporations and acquisitions there are lots of courses available. Nicely split by SharePoint version as well as particular interest group. Additionally, I found a couple of online blogs and community sites that I'm going to visit regularly during the next couple of weeks. Today's resource(s) Of course, I'm "all in" for the latest developer resources: SharePoint 2013 Developer Ramp-Up - Part 1 - Understanding the Platform and Developer Experience SharePoint 2013 Developer Ramp-Up - Part 2 SharePoint 2013 Developer Ramp-Up - Part 3 SharePoint 2013 Developer Ramp-Up - Part 4 SharePoint 2013 Developer Ramp-Up - Part 5 SharePoint 2013 Developer Ramp-Up - Part 6 I guess, I'm going to stick to the Pluralsight library until the end of this week. We'll see... Anyway, apart from the video material I came across a couple of other websites which I'd like to list here, too. That's mainly for personal reference instead of bookmarking in the browser, I'll use my own blog for that purpose. Atkinson's SharePoint Blog Düsseldorfer Jung Doerflers SharePoint Blog SharePoint Community Absolute SharePoint The links are in no preferential order and I added them as soon as I found them. Most probably, I'm going to report about specific articles from those resources during this challenge. So, stay tuned and I try to provide more details on certain topics. Takeaway First contact with the 'real stuff' in order to get an idea about software development in Microsoft SharePoint and beyond. Unfortunately and as already expected, the marketing department over at Microsoft seemed to have nothing better to do than to invent new names and baptise literally the same product with every release. Luckily, the release cycles between versions have been three years (roughly) - 2007, 2010, and 2013. Nonetheless, there will be a lot of version-specfic issues to tackle during this learning phase. Especially, when it's about historical expressions like 'WSS'* like I had it yesterday... It's going to be exciting and demanding to catch up with roughly 6-7 years of development and changes. Okay, let's face it. * WSS stands for Windows SharePoint Services 3.0 which forms the 'core engine' of SharePoint 2007. Part 1 of Andrew Connell's series on SharePoint 2013 for developers provides a brief history and overview of the various product names and their relation to the actual SharePoint version. I guess, I might create a cheat-sheet or something comparable in order to reduce the level of confusion while reading through other material: SharePoint 2007 (aka SharePoint v3 aka SharePoint 12) Windows SharePoint Services (WSS) 3.0 Microsoft Office SharePoint Server (MOSS) 2007 .NET Framework 3.0, 32-bit or 64-bit OS SharePoint 2010 (aka SharePoint v4 aka SharePoint 14) Microsoft SharePoint Foundation (SPF) 2010 Microsoft SharePoint Server (SPS) 2010 .NET Framework 3.5 SP1, 64-bit OS only SharePoint 2013 Microsoft SharePoint Foundation (SPF) 2013 Microsoft SharePoint Server (SPS) 2013 .NET Framework 4.5, 64-bit OS only After this quick excursion it is getting more interesting. SharePoint 2013 has a number of Development Practices and Techniques under the hood, and it will be quite a decision process depending on the task requirements to choose the correct path to go. At the moment, the following two options seem to be my future fields of operation: Client-Side Object Model (CSOM) REST API and OData syntax As part of my job assignment, I see myself developing within Visual Studio 2012/2013. Most probably the client development in C# will be using CSOM but of course I'll keep an eye on the REST API, too. JavaScript has quite a momentum since a while and it would a shame to ignore this type of opportunity and possibilities.

• Old School Wizardry Tip: Batch File Comments

  - by jkauffman

  Johnny, the Endangered Keyboard-Driven Windows User Some of my proudest, obscure Windows tricks are losing their relevance. I know I’m not alone. Keyboard shortcuts are going the way of the dodo. I used to induce fearful awe by slapping Ctrl+Shift+Esc in front of the lowly, pedestrian Windows users. No windows key on the keyboard? No problem: Ctrl+Esc. No menu key on the keyboard: Shift+F10. I am also firmly planted in the habit of closing windows with the Alt+Space menu (Alt+Space, C); and I harbor a brooding, slow=growing list of programs that fail to support this correctly (that means you, Paint.NET). Every time a new version of windows comes out, the support for some of these minor time-saving habits get pared out. Will I complain publicly? Nope, I know my old ways should be axed to conserve precious design energy. In fact, I disapprove of fierce un-intuitiveness for the sake of alleged productivity. Like vim, for example. If you approach a program after being away for 5 years, having to recall encyclopedic knowledge is a flaw. The RTFM disciples have lost. Anyway, some of the items in my arsenal of goofy time-saving tricks are still relevant today. I wanted to draw attention to one that’s stood the test of time. Remember Batch Files? Yes, it’s true, batch files are fading faster than the world of print. But they're not dead yet. I still run into some situations where I opt to use batch files. They are still relevant for build processes, or just various development workflow tools. Sure, there’s powershell, but there’s that stupid Set-ExecutionPolicy speed bump standing in your way; can you really spare the time to A) hunt down that setting on all machines affected and/or B) make futile efforts to convince your coworkers/boss that the hassle was worth it? When possible, I prefer the batch file wild card. And whenever I return to batch files, I end up researching some of the unintuitive aspects such as parameters, quote handling, and ERRORLEVEL. But I never have to remember to use “REM” for comment lines, because there’s a cleaner way to do them! Double Colon For Eye-Friendly Comments Here is a very simple batch file, with pretty much minimal content: @ECHO OFF SETLOCAL REM This is a comment ECHO This batch file doesn’t do much If you code on a daily basis, this may be more suitable to your eyes: @ECHO OFF SETLOCAL :: This is a comment ECHO This batch file doesn’t do much Works great! I imagine I find it preferable due to the similarity to comments in other situations: // or ;  or # I’ve often make visual pseudo-line breaks in my code, and this colon-based syntax works wonders: @ECHO OFF SETLOCAL :: Do stuff ECHO Doing Stuff :::::::::::::::::::::::::::: :: Do more stuff ECHO This batch file doesn’t do much Not only is it more readable, but there’s a slight performance benefit. The batch file engine sees this as an invalid line label and immediately reads the following line. Use that fact to your advantage if this trick leads you into heated nerd debate. Two Pitfalls to Avoid Be aware of that there are a couple situations where this hack will fail you. It most likely won’t be a problem unless you’re getting really sophisticated with your batch files. Pitfall #1: Inline comments @ECHO OFF SETLOCAL IF EXIST C:\SomeFile.txt GOTO END ::This will fail :END Unfortunately, this fails. You can only have whitespace to the left of your comments. Pitfall #2: Code Blocks @ECHO OFF SETLOCAL IF EXIST C:\SomeFile.txt (         :: This will fail         ECHO HELLO ) Code blocks, such as if statements and for loops, cannot contain these comments. This is ultimately due to the fact that entire code blocks are processed as a single line. I originally learned this from Rob van der Woude’s site. He goes into more depth about the behavior of the pitfalls as well, if you are interested in further details. I hope this trick earns you serious geek rep!

• Some Original Expressions

  - by Phil Factor

  Guest Editorial for Simple-Talk newsletterIn a guest editorial for the Simple-Talk Newsletter, Phil Factor wonders if we are still likely to find some more novel and unexpected ways of using the newer features of Transact SQL: or maybe in some features that have always been there! There can be a great deal of fun to be had in trying out recent features of SQL Expressions to see if  they provide new functionality.  It is surprisingly rare to find things that couldn’t be done before, but in a different   and more cumbersome way; but it is great to experiment or to read of someone else making that discovery.  One such recent feature is the ‘table value constructor’, or ‘VALUES constructor’, that managed to get into SQL Server 2008 from Standard SQL.  This allows you to create derived tables of up to 1000 rows neatly within select statements that consist of  lists of row values.  E.g. SELECT Old_Welsh, number FROM (VALUES ('Un',1),('Dou',2),('Tri',3),('Petuar',4),('Pimp',5),('Chwech',6),('Seith',7),('Wyth',8),('Nau',9),('Dec',10)) AS WelshWordsToTen (Old_Welsh, number) These values can be expressions that return single values, including, surprisingly, subqueries. You can use this device to create views, or in the USING clause of a MERGE statement. Joe Celko covered  this here and here.  It can become extraordinarily handy to use once one gets into the way of thinking in these terms, and I’ve rewritten a lot of routines to use the constructor, but the old way of using UNION can be used the same way, but is a little slower and more long-winded. The use of scalar SQL subqueries as an expression in a VALUES constructor, and then applied to a MERGE, has got me thinking. It looks very clever, but what use could one put it to? I haven’t seen anything yet that couldn’t be done almost as  simply in SQL Server 2000, but I’m hopeful that someone will come up with a way of solving a tricky problem, just in the same way that a freak of the XML syntax forever made the in-line  production of delimited lists from an expression easy, or that a weird XML pirouette could do an elegant  pivot-table rotation. It is in this sort of experimentation where the community of users can make a real contribution. The dissemination of techniques such as the Number, or Tally table, or the unconventional ways that the UPDATE statement can be used, has been rapid due to articles and blogs. However, there is plenty to be done to explore some of the less obvious features of Transact SQL. Even some of the features introduced into SQL Server 2000 are hardly well-known. Certain operations on data are still awkward to perform in Transact SQL, but we mustn’t, I think, be too ready to state that certain things can only be done in the application layer, or using a CLR routine. With the vast array of features in the product, and with the tools that surround it, I feel that there is generally a way of getting tricky things done. Or should we just stick to our lasts and push anything difficult out into procedural code? I’d love to know your views.

• Using a parser to locate faulty code

  - by ryan.riverside

  Lately I've been working a lot in PHP and have run into an abnormally large number of parsing errors. I realize these are my own fault and a result of sloppy initial coding on my part, but it's getting to the point that I'm spending more time resolving tags than developing. In the interest of not slamming my productivity, are there any tricks to locating the problem in the code? What I'd really be looking for would be a line to put in the code which would output the entire faulty tag in the parsing error, or something similar. Purely for reference sake, my current error is Parse error: syntax error, unexpected '}' in /home/content/80/9480880/html/cache/tpl_prosilver_viewtopic_body.html.php on line 50 (which refers to this): </dd><dd><?php if ($_poll_option_val['POLL_OPTION_RESULT'] == 0) { echo ((isset($this->_rootref['L_NO_VOTES'])) ? $this->_rootref['L_NO_VOTES'] : ((isset($user->lang['NO_VOTES'])) ? $user->lang['NO_VOTES'] : '{ NO_VOTES }')); } else { echo $_poll_option_val['POLL_OPTION_PERCENT']; } ?></dd> </dl> <?php }} if ($this->_rootref['S_DISPLAY_RESULTS']) { ?> <dl> <dt>&nbsp;</dt> <dd class="resultbar"><?php echo ((isset($this->_rootref['L_TOTAL_VOTES'])) ? $this->_rootref['L_TOTAL_VOTES'] : ((isset($user->lang['TOTAL_VOTES'])) ? $user->lang['TOTAL_VOTES'] : '{ TOTAL_VOTES }')); ?> : <?php echo (isset($this->_rootref['TOTAL_VOTES'])) ? $this->_rootref['TOTAL_VOTES'] : ''; ?></dd> </dl> <?php } if ($this->_rootref['S_CAN_VOTE']) { ?> <dl style="border-top: none;"> <dt>&nbsp;</dt> <dd class="resultbar"><input type="submit" name="update" value="<?php echo ((isset($this->_rootref['L_SUBMIT_VOTE'])) ? $this->_rootref['L_SUBMIT_VOTE'] : ((isset($user->lang['SUBMIT_VOTE'])) ? $user->lang['SUBMIT_VOTE'] : '{ SUBMIT_VOTE }')); ?>" class="button1" /></dd> </dl> <?php } if (! $this->_rootref['S_DISPLAY_RESULTS']) { ?> <dl style="border-top: none;"> <dt>&nbsp;</dt> <dd class="resultbar"><a href="<?php echo (isset($this->_rootref['U_VIEW_RESULTS'])) ? $this->_rootref['U_VIEW_RESULTS'] : ''; ?>"><?php echo ((isset($this->_rootref['L_VIEW_RESULTS'])) ? $this->_rootref['L_VIEW_RESULTS'] : ((isset($user->lang['VIEW_RESULTS'])) ? $user->lang['VIEW_RESULTS'] : '{ VIEW_RESULTS }')); ?></a></dd> </dl> <?php } ?> </fieldset></div>

• Too Clever for My Own Good

  - by AjarnMark

  Yesterday I caught myself being a little too clever for my own good with some ASP.NET code.  It seems that I have forgotten some of my good old classic HTML and JavaScript skills, and become too dependent on the .NET Framework and WebControls to do the work for me.  Here’s the scenario… In order to improve the User Interface and better communicate to the user when something is happening that they need to wait for, we have started to modify some of our larger (slower) pages to display messages like Processing… or Reloading… while they are cycling through a postback.  (Yes, I understand this could be improved by using AJAX / Callbacks and so on, but even then, you need to let your user know that they need to wait for that section to be re-rendered, so for the moment these pages will continue to use good ol’ Postbacks.)  It’s a very simple trick, really.  All I want to do is when some control triggers a postback, first run a little client-side JavaScript to hide the main contents of the page (such as a GridView) and display the appropriate message.  This lets the user know, “Hey, we’re doing something, don’t click another link or scroll and try to take action right now.” The first places I hooked this up were easy.  Most common cause of a postback:  Buttons.  And when you’re writing the markup or declarative code for an ASP:Button control, there is the handy OnClientClick property which is designed for just this purpose…to run client-side JavaScript before the postback occurs.  This is distinguished from the OnClick property which tells the control what Server-side code to run.  Great!  Done!  Easy! But then there are other controls like DropDownLists and CheckBoxes that we use on our pages with the AutoPostback=True setting which cause postbacks.  And these don’t have OnClientClick or OnClientSelectedIndexChanged events.  So I started getting creative, using an ASP:CustomValidator control in conjunction with setting the CausesValidation and ValidationGroup settings on these controls, which basically caused the action on the control to fire the Custom Validator, which was defined with a Client Side validation function which then did the hide content/show message code (and return a meaningless IsValid setting).  This also caused me to define a different ValidationGroup setting for my real data entry validator controls so that I could control them separately and only have them fire when I really wanted validation, and not just my show/hide trick. For a little while I was pretty proud of myself for coming up with this clever approach to get around what I considered to be a serious oversight on the DropDownList and CheckBox controls declarative syntax.  Then, in the midst of my smugness, just as I was about to commit my changes to the source code repository, it dawned on me that there is a much simpler and much more appropriate way to accomplish this.  All that I really needed to do was to put in my server-side code (I used the Page_Init section) a call to MyControl.Attributes.Add(“onClick”, “myJavaScriptFunctionName()”) for the checkboxes, and for the DropDownLists (which become select tags) use “onChange” instead of “onClick”.  This is exactly the type of thing that the Attributes collection is there for…so you can add attributes to be rendered with the control that you would have otherwise stuck right into the HTML markup if you had been doing this by hand in the first place. Ugh!  A few hours wasted on clever tricks that I ended up completely removing, but I did learn a lot more about custom validators and validation groups in the process.  And got a good reminder that all that stuff (HTML, JavaScript, and CSS) I learned back when I wrote classic ASP pages is still valuable today.  Oh, and one more thing…don’t get lulled into too much reliance on the the whiz-bang tool to do it for you.  After all, WebControls are just another layer of abstraction, and sometimes you need to dig down through the layers and get a little closer to the native language.

• What is the SharePoint Action Framework and Why do I need it ?

  - by SAF

  For those out there that are a little curious as to whether SAF is any use to your organisation, please read this FAQ.  What is SAF ? SAF is free to use. SAF is the "SharePoint Action Framework", it was built by myself and Hugo (plus a few others along the way). SAF is written entirely in C# code available from : http://saf.codeplex.com.   SAF is a way to automate SharePoint configuration changes. An Action is a command/class/task/script written in C# that performs a unit of execution against SharePoint such as "CreateWeb"  or "AddLookupColumn". A SAF Macro is collection of one or more Actions. SAF Macro can be run from Msbuild, a Feature, StsAdm or common plain old .Net code. Parameters can be passed to a Macro at run-time from a variety of sources such as "Environment Variable", "*.config", "Msbuild Properties", Feature Properties, command line args, .net code. SAF emits lots of trace statements at run-time, these can be viewed using "DebugView". One Action can pass parameters to another Action. Parameters can be set using Expression Syntax such as "DateTime.Now".  You should consider SAF is you suffer from one of the following symptoms... "Our developers write lots of code to deploy changes at release time - it's always rushed" "I don't want my developers shelling out to Powershell or Stsadm from a Feature". "We have loads of Console applications now, I have lost track of where they are, or what they do" "We seem to be writing similar scripts against SharePoint in lots of ways, testing is hard". "My scripts often have lots of errors - they are done at the last minute". "When something goes wrong - I have no idea what went wrong or how to solve it". "Our Features get stuck and bomb out half way through - there no way to roll them back". "We have tons of Features now - I can't keep track". "We deploy Features to run one-off tasks" "We have a library of reusable scripts, but, we can only run it in one way, sometimes we want to run it from MSbuild and a Feature". "I want to automate the deployment of changes to our development environment". "I would like to run a housekeeping task on a scheduled basis"   So I like the sound of SAF - what's the problems ?  Realistically, there are few things that need to be considered: Someone on your team will need to spend a day or 2 understanding SAF and deciding exactly how you want to use it. I would suggest a Tech Lead, SysAdm or SP Architect will need to download it, try out the examples, look through the unit tests. Ask us questions. Although, SAF can be downloaded and set to go in a few minutes, you will still need to address issues such as - "Do you want to execute your Macros in MsBuild or from a Feature ?" You will need to decide who is going to do your deployments - is it each developer to themself, or do you require a dedicated Build Manager ? As most environments (Dev, QA, Live etc) require different settings (e.g. Urls, Database names, accounts etc), you will more than likely want to define these and set a properties file up for each environment. (These can then be injected into Saf at run-time). There may be no Action to solve your particular problem. If this is the case, suggest it to us - we can try and write it, or write it yourself. It's very easy to write a new Action - we have an approach to easily unit test it, document it and author it. For example, I wrote one to deploy  a WSP in 2 hours the other day. Alternatively, Saf can also call Stsadm commands and Powershell scripts.   Anyway, I do hope this helps! If you still need help, or a quick start, we can also offer consultancy around SAF. If you want to know more give us a call or drop an email to [email protected]
