  • Entity Framework POCO Template for .NET 3.5

    If you are using Visual Studio 2010 and targeting .NET 3.5, you can still use the new T4 POCO template generation. I discovered this accidentally. (How else?) When you attempt to add a new code generation item from the model, there will be no templates available:   But if you click on Online Templates, there is an ADO.NET POCO Generator created by Microsoft: And it does the job as expected! Nice!...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • How can a code editor effectively hint at code nesting level - without using indentation?

    - by pgfearo
    I'm writing an XML text editor that provides 2 view options for the same XML text, one indented (virtually), the other left-justified. The motivation for the left-justified view is to help users 'see' the whitespace characters they're using for indentation of plain-text or XPath code without interference from indentation that is an automated side-effect of the XML context. I want to provide visual clues (in the non-editable part of the editor) for the left-justified mode that will help the user, but without getting too elaborate. I tried just using connecting lines, but that seemed too busy. The best I've come up with so far is shown in a mocked up screenshot of the editor below, but I'm seeking better/simpler alternatives (that don't require too much code). [Edit] Taking the heatmap idea (from: @jimp) I get something like this: or even these alternates:

  • Make ‘Associate’ the default checkin action

    When you associate a work item to a checkin, the work item will be resolved by default. Some teams have work items that are bigger then one checkin (although this is not recommended) and don’t want to resolve the work items during a checkin. The only ways to modify the behaviour are: - Remove the default checkin action from the work item type. Downside is that it is not possible in the UI to choose resolve if you actually want to resolve the work item. - Change the Resolve action to associate.   In Visual Studio 2010 you can modify this behaviour by changing a registry setting. Change value the following key to “False”. HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\TeamFoundation\SourceControl\Behavior @ResolveAsDefaultCheckinAction

  • BizTalk host throttling &ndash; Singleton pattern and High database size

    - by S.E.R.
    Originally posted on: http://geekswithblogs.net/SERivas/archive/2013/06/30/biztalk-host-throttling-ndash-singleton-pattern-and-high-database-size.aspxI have worked for some days around the singleton pattern (for those unfamiliar with it, read this post by Victor Fehlberg) and have come across a few very interesting posts, among which one dealt with performance issues (here, also by Victor Fehlberg). Simply put: if you have an orchestration which implements the singleton pattern, then performances will continuously decrease as the orchestration receives and consumes messages, and that behavior is more obvious when the orchestration never ends (ie : it keeps looping and never terminates or completes). As I experienced the same kind of problem (actually I was alerted by SCOM, which told me that the host was being throttled because of High database size), I thought it would be a good idea to dig a little bit a see what happens deep inside BizTalk and thus understand the reasons for this behavior. NOTE: in this article, I will focus on this High database size throttling condition. I will try and work on the other conditions in some not too distant future… Test conditions The singleton orchestration For the purpose of this study, I have created the following orchestration, which is a very basic implementation of a singleton that piles up incoming messages, then does something else when a certain timeout has been reached without receiving another message: Throttling settings I have two distinct hosts : one that hosts the receive port (basic FILE port) : Ports_ReceiveHostone that hosts the orchestration : ProcessingHost In order to emphasize the throttling mechanism, I have modified the throttling settings for each of these hosts are as follows (all other parameters are set to the default value): [Throttling thresholds] Message count in database: 500 (default value : 50000) Evolution of performance counters when submitting messages Since we are investigating the High database size throttling condition, here are the performance counter that we should take a look at (all of them are in the BizTalk:Message Agent performance object): Database sizeHigh database sizeMessage delivery throttling stateMessage publishing throttling stateMessage delivery delay (ms)Message publishing delay (ms)Message delivery throttling state durationMessage publishing throttling state duration (If you are not used to Perfmon, I strongly recommend that you start using it right now: it is a wonderful tool that allows you to open the hood and see what is going on inside BizTalk – and other systems) Database size It is quite obvious that we will start by watching the database size and high database size counters, just to see when the first reaches the configured threshold (500) and when the second rings the alarm. NOTE : During this test I submitted 600 messages, one message at a time every 10ms to see the evolution of the counters we have previously selected. It might not show very well on this screenshot, but here is what happened: From 15:46:50 to 15:47:50, the database size for the Ports_ReceiveHost host (blue line) kept growing until it reached a maximum of 504.At 15:47:50, the high database size alert fires At first I was surprised by this result: why is it the database size of the receiving host that keeps growing since it is the processing host that piles up messages? Actually, it makes total sense. This counter measures the size of the database queue that is being filled by the host, not consumed. Therefore, the high database size alert is raised on the host that fills the queue: Ports_ReceiveHost. More information is available on the Public MPWiki page. Now, looking at the Message publishing throttling state for the receiving host (green line), we can see that a throttling condition has been reached at 15:47:50: We can also see that the Message publishing delay(ms) (blue line) has begun growing slowly from this point. All of this explains why performances keep decreasing when a singleton keeps processing new messages: the database size grows and when it has exceeded the Message count in database threshold, the host is throttled and the publishing delay keeps increasing. Digging further So, what happens to the database queue then? Is it flushed some day or does it keep growing and growing indefinitely? The real question being: will the host be throttled forever because of this singleton? To answer this question, I set the Message count in database threshold to 20 (this value is very low in order not to wait for too long, otherwise I certainly would have fallen asleep in front of my screen) and I submitted 30 messages. The test was started at 18:26. At 18:56 (ie : exactly 30min later) the throttling was stopped and the database size was divided by 2. 30 min later again, the database size had dropped to almost zero: I guess I’ll have to find some documentation and do some more testing before I sort this out! My guess is that some maintenance job is at work here, though I cannot tell which one Digging even further If we take a look at the Message delivery throttling state counter for the processing host, we can see that this host was also throttled during the submission of the 600 documents: The value for the counter was 1, meaning that Message delivery incoming rate for the host instance exceeds the Message delivery outgoing rate * the specified Rate overdrive factor (percent) value. We will see this another day… :) A last word Let’s end this article with a warning: DO NOT CHANGE THE THROTTLING SETTINGS LIGHTLY! The temptation can be great to just bypass throttling by setting very high values for each parameter (or zero in some cases, which simply disables throttling). Nevertheless, always keep in mind that this mechanism is here for a very good reason: prevent your BizTalk infrastructure from exploding!! So whatever you do with those settings, do a lot of testing and benchmarking!

  • Create Chemistry Equations and Diagrams in Word

    - by Matthew Guay
    Microsoft Word is a great tool for formatting text, but what if you want to insert a chemistry formula or diagram?  Thanks to a new free add-in for Word, you can now insert high-quality chemistry formulas and diagrams directly from the Ribbon in Word. Microsoft’s new Education Labs has recently released the new Chemistry Add-in for Word 2007 and 2010.  This free download adds support for entering and editing chemistry symbols, diagrams, and formulas using the standard XML based Chemical Markup Language.  You can convert any chemical name, such as benzene, or formula, such as H2O, into a chemical diagram, standard name, or formula.  Whether you’re a professional chemist, just taking chemistry in school, or simply curious about the makeup of Citric Acid, this add-in is an exciting way to bring chemistry to your computer. This add-in works great on Word 2007 and 2010, including the 64 bit version of Word 2010.  Please note that the current version is still in beta, so only run it if you are comfortable running beta products. Getting Started Download the Chemistry add-in from Microsoft Education Labs (link below), and unzip the file.  Then, run the ChemistryAddinforWordBeta2.Setup.msi. It may inform you that you need to install the Visual Studio Tools for Office 3.0.  Simply click Yes to download these tools. This will open the download in your default browser.  Simply click run, or save and then run it when it is downloaded. Now, click next to install the Visual Studio Tools for Office as usual. When this is finished, run the ChemistryAddinforWordBeta2.Setup.msi again.  This time, you can easily install it with the default options. Once it’s finished installing, open Word to try out the Chemistry Add-in.  You will be asked if you want to install this customization, so click Install to enable it. Now you will have a new Chemistry tab in your Word ribbon.  Here’s the ribbon in Word 2010… And here it is in Word 2007.   Using the Chemistry Add-in It’s very easy to insert nice chemistry diagrams and formulas in Word with the Chemistry add-in.  You can quickly insert a premade diagram from the Chemistry Gallery: Or you can insert a formula from file.  Simply click “From File” and choose any Chemical Markup Language (.cml) formatted file to insert the chemical formula. You can also convert any chemical name to it’s chemical form.  Simply select the word, right-click, select “Convert to Chemistry Zone” and then click on its name. Now you can see the chemical form in the sidebar if you click the Chemistry Navigator button, and can choose to insert the diagram into the document.  Some chemicals will automatically convert to the diagram in the document, while others simply link to it in the sidebar.  Either way, you can display exactly what you want. You can also convert a chemical formula directly to it’s chemical diagram.  Here we entered H2O and converted it to Chemistry Zone: This directly converted it to the diagram directly in the document. You can click the Edit button on the top, and from there choose to either edit the 2D model of the chemical, or edit the labels. When you click Edit Labels, you may be asked which form you wish to display.  Here’s the options for potassium permanganate: You can then edit the names and formulas, and add or remove any you wish. If you choose to edit the chemical in 2D, you can even edit the individual atoms and change the chemical you’re diagramming.  This 2D editor has a lot of options, so you can get your chemical diagram to look just like you want. And, if you need any help or want to learn more about the Chemistry add-in and its features, simply click the help button in the Chemistry Ribbon.  This will open a Word document containing examples and explanations which can be helpful in mastering all the features of this add-in. All of this works perfectly, whether you’re running it in Word 2007 or 2010, 32 or 64 bit editions. Conclusion Whether you’re using chemistry formulas everyday or simply want to investigate a chemical makeup occasionally, this is a great way to do it with tools you already have on your computer.  It will also help make homework a bit easier if you’re struggling with it in high school or college.

  • BFCM &ndash; Big Fat Check Mark

    - by onefloridacoder
    I was installing TFS on my local laptop last week and just got around to setting up my initial collection using the TFS Console tool and “Bang!”  I received a message that told me that my local database didn’t have the full-text search option installed.  I remember the option in a (long) list of options and didn’t remember fiddling with it.   Whatever the reason, if you are installing TFS Basic on your box, make sure you have that little check ticked, or you won’t get the big fat one pictured above.  I installed SQL 2008 Developer edition which worked well for what I needed so far, and just needed to run the “Add Feature” option instead of the “Repair” option.

  • What are the advantages of version control systems that version each file separately?

    - by Mike Daniels
    Over the past few years I have worked with several different version control systems. For me, one of the fundamental differences between them has been whether they version files individually (each file has its own separate version numbering and history) or the repository as a whole (a "commit" or version represents a snapshot of the whole repository). Some "per-file" version control systems: CVS ClearCase Visual SourceSafe Some "whole-repository" version control systems: SVN Git Mercurial In my experience, the per-file version control systems have only led to problems, and require much more configuration and maintenance to use correctly (for example, "config specs" in ClearCase). I've had many instances of a co-worker changing an unrelated file and breaking what would ideally be an isolated line of development. What are the advantages of these per-file version control systems? What problems do "whole-repository" version control systems have that per-file version control systems do not?

  • What's a good open source java project for students to hack on?

    - by Evan Grim
    I'm working with a professor to develop a course teaching practical software development tools and methodology. We're looking for a sample code base that we can use for hands-on experience in each of the topics and as the basis for a semester-long project where students will work in a team to implement a feature or fix bugs. Here are some basic guidelines for the project that we'd like to come close to meeting: java based, ~50K SLOC, uses ant, depends upon some external library, has a test suite (preferably jUnit), friendly for development within eclipse, actively developed with a substantial history available within a version control system (such as subversion), the more "coolness" factor the better (to motivate the students), and preferably with some kind of user interface (e.g.: not just a library).

  • ADF Faces Layouts Demo - A Hidden Treasure

    - by shay.shmeltzer
    Layouting pages with ADF Faces containers is sometimes not as simple as we would have liked it to be - especially for people who are just getting started. There are some tricks that can help you achieve the layout that you are looking for. One great way to learn some of those tricks is to look at the new "Visual Design" section of the ADF Faces Hosted demo. For example look at the Form Layout part - and you'll see nicely aligned forms that contain various UI layout scenarios. Want to learn how this has been achieved? - just click the "page source" link at the top right - and you can see how that layout has been done. Don't forget that you can also download the full demo source here. One other good resource I came across today is the "Designing well known websites with ADF Rich Faces" presentation from Maiko Rocha and George Magessy - it's missing the demo part - but you can still learn a lot from the slides.

  • Smooth terrain rendering

    - by __dominic
    I'm trying to render a smooth terrain with Direct3D. I've got a 50*50 grid with all y values = 0, and a set of 3D points that indicate the location on the grid and depth or height of the "valley" or "hill". I need to make the y values of the grid vertices higher or lower depending on how close they are to each 3D point. Thus, in the end I should have a smooth terrain renderer. I'm not sure at all what way I can do this. I've tried changing the height of the vertices based on the distance to each point just using this basic formula: dist = a² + b² + c² where a, b and c are the x, y, and z distance from a vertex to a 3D point. The result I get with this is not smooth at all. I'm thinking there is probably a better way. Here is a screenshot of what I've got for the moment: https://dl.dropbox.com/u/2562049/terrain.jpg

  • XNA Notes 004

    - by George Clingerman
    The XNA community has been crazy busy again. It always make me fee like such a slacker collecting all of these notes as I see the tremendous output from people all over the world and it’s incredible and humbling. There are some amazingly skilled people working with XNA. On another not, I’m going to take a minute to get on my soapbox and say, if you are developing ANYTHING and are not using some sort of source/revision control, START IMMEDIATELY. This applies to teams of one. Projects for fun. And “I back up my hard drive” or “I use dropbox!” does NOT count as using source control. You’ll be doing yourself a HUGE favor if you find one, learn to use it and integrate it into your everyday workflow. I personally use Subversion. It’s hosted offsite at xp.dev.com and I use TortoiseSVN as my front end to interface with the repository. It’s simple and easy to use and has saved me from myself so many time. Honestly, get setup with some type of source control immediately. If you don’t understand how, grab another developer that does and have them walk you through setup and the basics of using it. Ok, I’m done.

I have recently been hired to build a new, fairly complex site from scratch, for which I will be working with an experienced programmer with whom I have worked extensively in the past. Although I have a decent understanding of certain technical concepts relating to web development, I would like to build a better appreciation of the programmer's craft, in order to improve communication with my programmer, as well as the client. I have heard Code Complete is quite a good book for this. Other than reading this and learning some basic programming, are there any other books or resources that could be recommended to the non-programmer who does not wish to become a programmer, yet wishes to understand the most common concepts involved in building software, web-based or otherwise?

  • Finding a problem in some task [closed]

    - by nagisa
    Recently I competed in nation wide programming contest finals. Not unexpectedly all problems were algorithmic. I lost (40 points out of 600. Winner got ~300). I know why I lost very well - I don't know how to find actual problem in those obfuscated tasks which are life-blood of every competition. I think that being self-taught and not well versed in algorithms got me too. As side effect of learning things myself I know how to search for information, however all I could find are couple questions about learning algorithms. For now I put Python Algorithms: Mastering Basic Algorithms in the Python Language and Analysis of Algorithms which I found in those questions to my "to read" list. That leaves my first problem of not knowing how to find a problem unsolved. Will that ability come with learning algorithms? Or does it need some special attention? Any suggestions are welcomed.

  • SnagIt Live Writer Plug-in Updated

    - by Rick Strahl
    Ah, I love SnagIt from TechSmith and I use the heck out of it almost every day. So no surprise that I've decided some time ago to integrate SnagIt into a few applications that require screen shots extensively. It's been a while since I've posted an update to my small SnagIt Windows Live Writer plug-in. There have been a few nagging issues that have crept up with recent changes in the way SnagIt handles captures in recent versions and they have been addressed in this update of SnagIt. Personally I love SnagIt and use it extensively mostly for blogging, but also for writing documentation and articles etc. While there are many other (and also free) tools out there to do basic screen captures, SnagIt continues to be the most convenient tool for me with its nice built in capture and effects editor that makes creating professional looking captures childishly simple. And maybe even more importantly: SnagIt has a COM interface that can be automated and  makes it super easy to embed into other applications. I've built plugins for SnagIt as well as for one of my company's own tools, Html Help Builder. If you use the Windows Live Writer offline WebLog Editor to write blog posts and have a copy of SnagIt it's probably worth your while to check this out if you haven't already. In case you haven't, this plugin integrates SnagIt with Live Writer so you can easily capture and edit content and embed it into a post. Captures are shown in the SnagIt Preview editor where you can edit the image and apply image markup or effects, before selecting Finish (or Cancel). The final image can then be pasted directly into your Live Writer post. When installed the SnagIt plug-in shows up on the PlugIn list or in the Plug-Ins toolbar shortcut: Once you select the Plug in you get the capture window that allows you to customize the capture process which includes most of the useful SnagIt capture options: Once you're done capturing the image shows up in the SnagIt Image Editor and you can crop, mark up and apply effects. When done you click the Finish button and the image is embedded right into your blog post. Easy - how do you think the images in this blog entry got in here? The beauty of SnagIt is that it's all easily integrated - Capturing, editing and embedding, it only takes a few seconds to do it all especially if you save image effect presets in SnagIt. What's updated The main issue addressed in this update has to do with the plug-in updates the Live Writer window. When a capture starts Live Writer gets minimized to get out of the way to let you pick your capture source. When the capture is complete and the image has been embedded Live Writer is activated once again. Recent versions of SnagIt however had changed the Window positioning of SnagIt so that Live Writer ended up popping up back behind the SnagIt window which was pretty annoying. This update pushes Live Writer back to the top of the window stack using some delaying tactics in the code. There have also been a few small changes to the way the code interacts with the COM object which is more reliable if a capture fails or SnagIt blows up or is locked because it's already in a capture outside of the automation interface. Source Code SnagIt Automation is something I actually use a lot. As mentioned I've integrated this automation into Live Writer as well as my documentation tool Html Help Builder, which I use just about daily. The SnagIt integration has a similar interface in that application and provides similar functionality. It's quite useful to integrate SnagIt into other applications. Because it's quite useful to embed SnagIt into other apps there's source code that you can download and embed into your own applications. The code includes both the dialog class that is automated from Live Writer, as well as the basic capture component that captures images to a disk file. Resources Download the SnagIt Capture Plug-in Installer An MSI installer that you can run that will install the plug-in into Live Writer's PlugIns directory. Source Code to the SnagIt Capture Plug-in Contains the plug-in assembly, as well as the source code to the plug-in and the setup project.© Rick Strahl, West Wind Technologies, 2005-2011Posted in Live Writer  WebLog   Tweet (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); })();

  • Great Surprise &ndash; MSDN Ultimate

    - by MarkPearl
    So, I attended the Microsoft Community Evening. The attendance was better than I was expecting for December and we had our first Programming Languages Meeting where Gary did a great presentation on an intro to Ruby. The best surprize of the evening happened when I was about to leave, Robert MacLean asked me how we did our MS licensing – the fact being that we were about to reach the end of our empower license with Microsoft and that I had no idea how we were going to afford upgrading it early next year. Well, out comes a Microsoft Visual Studio Ultimate with MSDN 12 month subscription. An absolute awesome gift – thanks Robert! Best gift ever!

  • Back from Russia

    - by Stephen Walther
    Thanks everyone who came to my talks on ASP.NET Web Forms and MVC in Moscow last week!  Here are the slide decks and demo code for the two talks (You need Visual Studio 2010):   What’s New in ASP.NET MVC 2?   What’s New in ASP.NET 4 Web Forms?   I had a great time in Russia. On the second day, I had an opportunity to walk around Moscow. Here’s a picture of me standing in Red Square:   Here’s a picture of me eating Chicken Kiev with Microsoft evangelist James Senior. James has just started his worldwide Web Camp tour to promote ASP.NET 4. He is traveling non-stop country to country. After Russia, he is off to China and Australia. You can find out more about the Web Camps here: http://www.webcamps.ms/

  • Formal Languages, Inductive Proofs &amp; Regular Expressions

    - by MarkPearl
    So I am slogging away at my UNISA stuff. I have just finished doing the initial once non stop read through the first 11 chapters of my COS 201 Textbook - “Introduction to Computer Theory 2nd Edition” by Daniel Cohen. It has been an interesting couple of days, with familiar concepts coming up as well as some new territory. In this posting I am going to cover the first couple of chapters of the book. Let start with Formal Languages… What exactly is a formal language? Pretty much a no duh question for me but still a good one to ask – a formal language is a language that is defined in a precise mathematical way. Does that mean that the English language is a formal language? I would say no – and my main motivation for this is that one can have an English sentence that is correct grammatically that is also ambiguous. For example the ambiguous sentence: "I once shot an elephant in my pyjamas.” For this and possibly many other reasons that I am unaware of, English is termed a “Natural Language”. So why the importance of formal languages in computer science? Again a no duh question in my mind… If we want computers to be effective and useful tools then we need them to be able to evaluate a series of commands in some form of language that when interpreted by the device no confusion will exist as to what we were requesting. Imagine the mayhem that would exist if a computer misinterpreted a command to print a document and instead decided to delete it. So what is a Formal Language made up of… For my study purposes a language is made up of a finite alphabet. For a formal language to exist there needs to be a specification on the language that will describe whether a string of characters has membership in the language or not. There are two basic ways to do this: By a “machine” that will recognize strings of the language (e.g. Finite Automata). By a rule that describes how strings of a language can be formed (e.g. Regular Expressions). When we use the phrase “string of characters”, we can also be referring to a “word”. What is an Inductive Proof? So I am not to far into my textbook and of course it starts referring to proofs and different types. I have had to go through several different approaches of proofs in the past, but I can never remember their formal names , so when I saw “inductive proof” I thought to myself – what the heck is that? Google to the rescue… An inductive proof is like a normal proof but it employs a neat trick which allows you to prove a statement about an arbitrary number n by first proving it is true when n is 1 and then assuming it is true for n=k and showing it is true for n=k+1. The idea is that if you want to show that someone can climb to the nth floor of a fire escape, you need only show that you can climb the ladder up to the fire escape (n=1) and then show that you know how to climb the stairs from any level of the fire escape (n=k) to the next level (n=k+1). Does this sound like a form of recursion? No surprise then that in the same chapter they deal with recursive definitions. An example of a recursive definition for the language EVEN would the 3 rules below: 2 is in EVEN If x is in EVEN then so is x+2 The only elements in the set EVEN are those that be produced by the rules above. Nothing to exciting… So if a definition for a language is done recursively, then it makes sense that the language can be proved using induction. Regular Expressions So I am wondering to myself what use is this all – in fact – I find this the biggest challenge to any university material is that it is quite hard to find the immediate practical applications of some theory in real life stuff. How great was my joy when I suddenly saw the word regular expression being introduced. I had been introduced to regular expressions on Stack Overflow where I was trying to recognize if some text measurement put in by a user was in a valid form or not. For instance, the imperial system of measurement where you have feet and inches can be represented in so many different ways. I had eventually turned to regular expressions as an easy way to check if my parser could correctly parse the text or not and convert it to a normalize measurement. So some rules about languages and regular expressions… Any finite language can be represented by at least one if not more regular expressions A regular expressions is almost a rule syntax for expressing how regular languages can be formed regular expressions are cool For a regular expression to be valid for a language it must be able to generate all the words in the language and no other words. This is important. It doesn’t help me if my regular expression parses 100% of my measurement texts but also lets one or two invalid texts to pass as well. Okay, so this posting jumps around a bit – but introduces some very basic fundamentals for the subject which will be built on in later postings… Time to go and do some practical examples now…
