  • What is the quickest way to indent a block of text with spaces for use within a web browser?

    - by ændrük
    I occasionally have the need to indent a block of text with spaces for use within a web browser, for example, when formatting a code block on this site or in a post on Launchpad. So far I've just done it by hand by copying four spaces to the clipboard and then mashing keys really fast: ?, Home, Ctrl+V (repeat) What is the quickest way to accomplish this? Copying and pasting to another program? (Which?) A Firefox or Chrome browser extension? A command to directly modify the clipboard contents? An auto-typing program?

  • Entity Framework Code First: Get Entities From Local Cache or the Database

    - by Ricardo Peres
    Entity Framework Code First makes it very easy to access local (first level) cache: you just access the DbSet<T>.Local property. This way, no query is sent to the database, only performed in already loaded entities. If you want to first search local cache, then the database, if no entries are found, you can use this extension method: 1: public static class DbContextExtensions 2: { 3: public static IQueryable<T> LocalOrDatabase<T>(this DbContext context, Expression<Func<T, Boolean>> expression) where T : class 4: { 5: IEnumerable<T> localResults = context.Set<T>().Local.Where(expression.Compile()); 6:  7: if (localResults.Any() == true) 8: { 9: return (localResults.AsQueryable()); 10: } 11:  12: IQueryable<T> databaseResults = context.Set<T>().Where(expression); 13:  14: return (databaseResults); 15: } 16: }

  • Google I/O 2010 - Google Wave API design principles

    Google I/O 2010 - Google Wave API design principles Google I/O 2010 - Google Wave API design principles + anatomy of a great extension Wave 201 Pamela Fox, Michael Goderbauer (Hasso Plattner Institute) Google Wave is all about collaboration. The most successful extensions are user-friendly and collaborative. Wave robots should be as intuitive to communicate with as a human, and play well with other robots; Wave gadgets should extend the metaphors of the textual collaboration into the visual. In this talk, we'll discuss the design and privacy principles you should consider while building extensions, and show examples of extensions that demonstrate these principles.

  • What's wrong with relative imports in Python?

    - by Oddthinking
    I recently upgraded versions of pylint, a popular Python style-checker. It has gone ballistic throughout my code, pointing out places where I import modules in the same package, without specifying the full package path. The new error message is W0403. W0403: Relative import %r, should be %r Used when an import relative to the package directory is detected. Example For example, if my packages are structured like this: /cake /__init__.py /icing.py /sponge.py /drink and in the sponge package I write: import icing instead of import cake.icing I will get this error. While I understand that not all Pylint messages are of equal importance, and I am not afraid to dismiss them, I don't understand why such a practice is considered a poor idea. I was hoping someone could explain the pitfalls, so I could improve my coding style rather than (as I currently plan to do) turning off this apparently spurious warning.

  • ASP.NET Web API - Screencast series Part 4: Paging and Querying

    - by Jon Galloway
    We're continuing a six part series on ASP.NET Web API that accompanies the getting started screencast series. This is an introductory screencast series that walks through from File / New Project to some more advanced scenarios like Custom Validation and Authorization. The screencast videos are all short (3-5 minutes) and the sample code for the series is both available for download and browsable online. I did the screencasts, but the samples were written by the ASP.NET Web API team. In Part 1 we looked at what ASP.NET Web API is, why you'd care, did the File / New Project thing, and did some basic HTTP testing using browser F12 developer tools. In Part 2 we started to build up a sample that returns data from a repository in JSON format via GET methods. In Part 3, we modified data on the server using DELETE and POST methods. In Part 4, we'll extend on our simple querying methods form Part 2, adding in support for paging and querying. This part shows two approaches to querying data (paging really just being a specific querying case) - you can do it yourself using parameters passed in via querystring (as well as headers, other route parameters, cookies, etc.). You're welcome to do that if you'd like. What I think is more interesting here is that Web API actions that return IQueryable automatically support OData query syntax, making it really easy to support some common query use cases like paging and filtering. A few important things to note: This is just support for OData query syntax - you're not getting back data in OData format. The screencast demonstrates this by showing the GET methods are continuing to return the same JSON they did previously. So you don't have to "buy in" to the whole OData thing, you're just able to use the query syntax if you'd like. This isn't full OData query support - full OData query syntax includes a lot of operations and features - but it is a pretty good subset: filter, orderby, skip, and top. All you have to do to enable this OData query syntax is return an IQueryable rather than an IEnumerable. Often, that could be as simple as using the AsQueryable() extension method on your IEnumerable. Query composition support lets you layer queries intelligently. If, for instance, you had an action that showed products by category using a query in your repository, you could also support paging on top of that. The result is an expression tree that's evaluated on-demand and includes both the Web API query and the underlying query. So with all those bullet points and big words, you'd think this would be hard to hook up. Nope, all I did was change the return type from IEnumerable<Comment> to IQueryable<Comment> and convert the Get() method's IEnumerable result using the .AsQueryable() extension method. public IQueryable<Comment> GetComments() { return repository.Get().AsQueryable(); } You still need to build up the query to provide the $top and $skip on the client, but you'd need to do that regardless. Here's how that looks: $(function () { //--------------------------------------------------------- // Using Queryable to page //--------------------------------------------------------- $("#getCommentsQueryable").click(function () { viewModel.comments([]); var pageSize = $('#pageSize').val(); var pageIndex = $('#pageIndex').val(); var url = "/api/comments?$top=" + pageSize + '&$skip=' + (pageIndex * pageSize); $.getJSON(url, function (data) { // Update the Knockout model (and thus the UI) with the comments received back // from the Web API call. viewModel.comments(data); }); return false; }); }); And the neat thing is that - without any modification to our server-side code - we can modify the above jQuery call to request the comments be sorted by author: $(function () { //--------------------------------------------------------- // Using Queryable to page //--------------------------------------------------------- $("#getCommentsQueryable").click(function () { viewModel.comments([]); var pageSize = $('#pageSize').val(); var pageIndex = $('#pageIndex').val(); var url = "/api/comments?$top=" + pageSize + '&$skip=' + (pageIndex * pageSize) + '&$orderby=Author'; $.getJSON(url, function (data) { // Update the Knockout model (and thus the UI) with the comments received back // from the Web API call. viewModel.comments(data); }); return false; }); }); So if you want to make use of OData query syntax, you can. If you don't like it, you're free to hook up your filtering and paging however you think is best. Neat. In Part 5, we'll add on support for Data Annotation based validation using an Action Filter.

  • SLK opens SCORM package as a ZIP file

    - by Cherie Riesberg
    Symptom: After installing SharePoint Learning Kit successfully, (http://www.codeplex.com/SLK), everything works except that the SCORM package (a ZIP extension) is opening as a ZIP file instead of a course. You get the normal ZIP message "Do you want to open or save this file?" Problem: The package is zipped at the upper folder level and does not create a manifest that allows SharePoint to recognize it as a SCORM file instead of a ZIP file. Solution: Add the contents of the course to the ZIP, not the outer (uppermost) folder.  This creates a ZIP file that SharePoint can recognize as a SCORM package.

  • Monitoring almost anything with BizTalk 360

    - by Michael Stephenson
    When you work in an integration environment it is common that you will find yourself in a situation where you integrate with some unusual applications or have some unusual dependencies. That is the nature of integration. When you work with BizTalk one of the common problems is that BizTalk often is the place where problems with applications you integrate with are highlighted and these external applications may have poor monitoring solutions. Fortunately if you are a working with a customer who uses BizTalk 360 then it contains a feature called the "Web Endpoint Manager". Typically the web endpoint manager is used to monitor web services that you integrate with and will ping them at appropriate times to make sure they return the expected HTTP status code. When you have an usual situation where you want to monitor something which is key to the success to your solution but you find yourself having to consider a significant custom solution to monitor the external dependency then the Web Endpoint Manager could be your friend. The endpoint manager monitors a url and checks for a certain status code. This means that you can create your own aspx web page and then make BizTalk 360 monitor this web page. Behind the web page you could write any code you wished. An example of this is architecture is shown in the below diagram.     In the custom web page you would implement some custom code to do whatever it is that you want to monitor. In the below code snippet you can see how the Page_Load default method is doing some kind of check then depending on the result of the check it returns a certain HTTP code. protected void Page_Load(object sender, EventArgs e) { var result = CheckSomething();   if (result == "Success") Response.StatusCode = 202; else if (result == "DatabaseError") Response.StatusCode = 510; else if (result == "SystemError") Response.StatusCode = 512; else Response.StatusCode = 513;   }   In BizTalk 360 you would go into the Monitor and Notify tab and then to BizTalk Environment which gives you access to the Web Endpoint Manager. You need an alarm setup which configures how the endpoint will be checked. I'm not going to go through the details of creating the alarm as this is already documented in the BizTalk 360 documentation. One point to note is that in the example I am using I setup a threshold alarm which means that the url is checked about every minute and if there is an error that persists for a period of time then the alarm will raise the alert notification. In my example I configured the alarm to fire if the error persisted for 3 minutes. The below picture shows accessing the endpoint manager.   In the web endpoint manager you would then configure your endpoint to monitor and the HTTP response code which indicates all is working fine. The below picture shows this. I now have my endpoint monitoring setup and BizTalk 360 should be checking my custom endpoint to see that it is available. If I wanted to manually sanity check that the endpoints I have registered are working fine then clicking the Refresh button will show if they are all good or not. If my custom ASP.net page which is checking my dependency gets a problem you will see in the endpoint manager that the status code does not match the expected return code and your endpoints will display in red and you can see the problem. The below picture shows this. If I use specific HTTP response codes for the errors the custom ASP.net page might encounter I can easily interpret these to know what the problem is. Using the alarms and notifications with BizTalk 360 it means when your endpoint goes into an error state you can easily configure email or SMS notifications from BizTalk 360 to tell you that your endpoint is having problems and you can use BizTalk 360 to help correlate what the problem is to allow you to investigate further. Below you can see the email which tells me my endpoint is not working.   When everything returns to normal you will see the status is now fixed and you will see a situation like below where you can see the WebEndpoints are now green and the return code matches what is expected.   Conclusion As you can see it is really easy to plug your own custom ASP.net page into the BizTalk 360 web endpoint monitoring feature. This extension then gives you the power to really extend the monitoring to almost anything you want as long as you can write some .net code to check that the dependency is available and working. It would be interesting to hear of any ideas people have around things they would monitor with this extension. More details on the end point monitor can be found on the following link: http://www.biztalk360.com/tour/monitoring_notifications

  • Ghost Incognito Automatically Loads Incognito Mode Based on Domain

    - by Jason Fitzpatrick
    Chrome: Ghost Incognito mode is a simple Chrome extension that automatically launches Incognito mode on a domain-by-domain basis. If you routinely visit the same sites using Incognito Mode, Ghost Incognito allows you to flag domains. By default it turns on Incognito for all .XXX domains and, once you select some domains, for any that you specify. Thus if you flag angrybirds.com, as we did for our test run of the app, every time you visit angrybirds.com or a sub-domain there of such as shop.angrybirds.com, you’ll be automatically directed to a new Incognito tab–no input from you necessary.

  • Ubuntu 13.10 AdobeAIR application: Failed to load module "unity-gtk-module"

    - by nobuzz
    I have installed AdobeAIR on 13.10, but am getting the following error messages when using: Gtk-Message: Failed to load module "overlay-scrollbar" Gtk-Message: Failed to load module "unity-gtk-module" Has someone faced this issue. I looked at comment giving a possible resolution here , but that didn't help, as I already have those packages installed. Basically to install AdobeAIR, being a 32-bit, I had to install various i386 packages: libgtk2.0-0:i386 libnss3-1d:i386 libnspr4-0d:i386 lib32nss-mdns libxml2:i386 libxslt1.1:i386 When I run the program as root, it opens up properly without errors. But that is not an option. Could it be a problem that necessary modules are not getting loaded on non-root user's environment.

  • How to install new Intel Ethernet driver

    - by Alex Farber
    Ubuntu 12.04 x64 doesn't recognize newest Intel Ethernet adapter on my desktop (Intel Ethernet Connection i217-V). I downloaded required driver from Intel and compiled it using make. Now I have: alex@alex64-six:~$ find / -name 'e1000e.ko' 2>/dev/null /home/alex/Documents/IntelEthernetDriver/e1000e-3.0.4/src/e1000e.ko /lib/modules/3.2.0-64-generic/kernel/drivers/net/ethernet/intel/e1000e/e1000e.ko The first line is new driver compiled from Intel sources. The second line is probably existing driver from Ubuntu distribution, which doesn't recognize new Ethernet adapter. How can I apply the new driver instead of existing one? Any other solution is welcome. For now, I cannot upgrade to latest Ubuntu release, because I use some third-party products.

  • How do I know I'm using kubuntu?

    - by Adobe
    I installed Kubuntu image long time ago, and did several release upgrades since that. I have package kubuntu-full installed, and boot into KDE. Currently it looks like I'm using ubuntu: ~: lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 13.10 Release: 13.10 Codename: saucy There's not a single kubuntu word in my /etc/apt/sources.list, or is it Kubuntu = Ubuntu - Unity + KDE now? For example there's a Pre-Alpha Ubuntu Thar already, but no Kubuntu one. Would I get Kubuntu Thar, by installing Ubuntu Thar in the way mentioned above? Probably Kubuntu team now are the guys responsible for KDE working in Ubuntu.

  • CLR via C# 3rd Edition is out

    - by Abhijeet Patel
    Time for some book news update. CLR via C#, 3rd Edition seems to have been out for a little while now. The book was released in early Feb this year, and needless to say my copy is on it’s way. I can barely wait to dig in and chew on the goodies that one of the best technical authors and software professionals I respect has in store. The 2nd edition of the book was an absolute treat and this edition promises to be no less. Here is a brief description of what’s new and updated from the 2nd edition. Part I – CLR Basics Chapter 1-The CLR’s Execution Model Added about discussion about C#’s /optimize and /debug switches and how they relate to each other. Chapter 2-Building, Packaging, Deploying, and Administering Applications and Types Improved discussion about Win32 manifest information and version resource information. Chapter 3-Shared Assemblies and Strongly Named Assemblies Added discussion of TypeForwardedToAttribute and TypeForwardedFromAttribute. Part II – Designing Types Chapter 4-Type Fundamentals No new topics. Chapter 5-Primitive, Reference, and Value Types Enhanced discussion of checked and unchecked code and added discussion of new BigInteger type. Also added discussion of C# 4.0’s dynamic primitive type. Chapter 6-Type and Member Basics No new topics. Chapter 7-Constants and Fields No new topics. Chapter 8-Methods Added discussion of extension methods and partial methods. Chapter 9-Parameters Added discussion of optional/named parameters and implicitly-typed local variables. Chapter 10-Properties Added discussion of automatically-implemented properties, properties and the Visual Studio debugger, object and collection initializers, anonymous types, the System.Tuple type and the ExpandoObject type. Chapter 11-Events Added discussion of events and thread-safety as well as showing a cool extension method to simplify the raising of an event. Chapter 12-Generics Added discussion of delegate and interface generic type argument variance. Chapter 13-Interfaces No new topics. Part III – Essential Types Chapter 14-Chars, Strings, and Working with Text No new topics. Chapter 15-Enums Added coverage of new Enum and Type methods to access enumerated type instances. Chapter 16-Arrays Added new section on initializing array elements. Chapter 17-Delegates Added discussion of using generic delegates to avoid defining new delegate types. Also added discussion of lambda expressions. Chapter 18-Attributes No new topics. Chapter 19-Nullable Value Types Added discussion on performance. Part IV – CLR Facilities Chapter 20-Exception Handling and State Management This chapter has been completely rewritten. It is now about exception handling and state management. It includes discussions of code contracts and constrained execution regions (CERs). It also includes a new section on trade-offs between writing productive code and reliable code. Chapter 21-Automatic Memory Management Added discussion of C#’s fixed state and how it works to pin objects in the heap. Rewrote the code for weak delegates so you can use them with any class that exposes an event (the class doesn’t have to support weak delegates itself). Added discussion on the new ConditionalWeakTable class, GC Collection modes, Full GC notifications, garbage collection modes and latency modes. I also include a new sample showing how your application can receive notifications whenever Generation 0 or 2 collections occur. Chapter 22-CLR Hosting and AppDomains Added discussion of side-by-side support allowing multiple CLRs to be loaded in a single process. Added section on the performance of using MarshalByRefObject-derived types. Substantially rewrote the section on cross-AppDomain communication.

  • Trying to do a batch rename, can't figure out the proper RegEx

    - by trezy
    I'm trying to rename my movie collection. All of the files are currently named using dots instead of spaces, i.e. Men.in.Black.avi. I want to replace all of the dots with spaces which isn't terribly difficult, but I need to preserve the last dot for the file extension, i.e. .avi, .mp4, .ogg, etc. My Googling has provided no solutions. I'm also a Javascript developer and could see some snazzy applications for it. So, any suggestions?

  • Exporting SWF With Transparent Background For Scaleform/UDK

    - by Alex Shepard
    After looking all over in the UDN and forums I have yet to find a solution for this: I am currently using Flash CS3 and Actionscript 2.0 to build my scaleform menus and I can use them in the UDK. For various reasons I can't use the handy plugin Autodesk supplies to enable this export so I publish my flash documents to swf the old fassioned way and manually use the gfxexport.exe tool to get my .gfx file. I can then import into the UDK the normal way. My problem is that the flash movies that I import will not alpha blend even if the material is set to blend in the alpha channel of the target render texture. My project images are set up to export properly. My classpath for Actionscript 2.0 is set to the correct location. My HTML publish settings have window mode set to Transparent Windowless. Is it possible to export without the scaleform flash extension and still get the desired effects and if so how might I do so? Am I merely missing something from my project setup?

  • Oracle ATG Web Commerce 10 Implementation Developer Boot Camp - Reading (UK) - October 1-12, 2012

    - by Richard Lefebvre
    REGISTER NOW: Oracle ATG Web Commerce 10 Implementation Developer Boot Camp Reading, UK, October 1-12, 2012! OPN invites you to join us for a 10-day implementation bootcamp on Oracle ATG Web Commerce in Reading, UK from October 1-12, 2012.This 10-day boot camp is designed to provide partners with hands-on experience and technical training to successfully build and deploy Oracle ATG Web Commerce 10 Applications. This particular boot camp is focused on helping partners develop the essential skills needed to implement every aspect of an ATG Commerce Application from scratch, (not CRS-based), with a specific goal of enabling experienced Java/J2EE developers with a path towards becoming functional, effective, and contributing members of an ATG implementation team. Built for both new and experienced ATG developers alike, the collaborative nature of this program and its exercises, have proven to be highly effective and extremely valuable in learning the best practices for implementing ATG solutions. Though not required, this bootcamp provides a structured path to earning a Certified Oracle ATG Web Commerce 10 Specialization! What Is Covered: This boot camp is for Application Developers and Software Architects wanting to gain valuable insight into ATG application development best practices, as well as relevant and applicable implementation experience on projects modeled after four of the most common types of applications built on the ATG platform. The following learning objectives are all critical, and are of equal priority in enabling this role to succeed. This learning boot camp will help with: Building a basic functional transaction-ready ATG Web Commerce 10 Application. Utilizing ATG’s platform features such as scenarios, slots, targeters, user profiles and segments, to create a personalized user experience. Building Nucleus components to support and/or extend application functionality. Understanding the intricacies of ATG order checkout and fulfillment. Specifying, designing and implementing new commerce features in ATG 10. Building a functional commerce application modeled after four of the most common types of applications built on the ATG platform, within an agile-based project team environment and under simulated real-world project conditions. Duration: The Oracle ATG Web Commerce 10 Implementation Developer Boot Camp is an instructor-led workshop spanning 10 days. Audience: Application Developers Software Architects Prerequisite Training and Environment Requirements: Programming and Markup Experience with Java J2EE, JavaScript, XML, HTML and CSS Completion of Oracle ATG Web Commerce 10 Implementation Specialist Development Guided Learning Path modules Participants will be required to bring their own laptop that meets the minimum specifications:   64-bit PC and OS (e.g. Windows 7 64-bit) 4GB RAM or more 40GB Hard Disk Space Laptops will require access to the Internet through Remote Desktop via Windows. Agenda Topics: Week 1 – Day 1 through 5 Build a Basic Commerce Application In week one of the boot camp training, we will apply knowledge learned from the ATG Web Commerce 10 Implementation Developer Guided Learning Path modules, towards building a basic transaction-ready commerce application. There will be little to no lectures delivered in this boot camp, as developers will be fully engaged in ATG Application Development activities and best practices. Developers will work independently on the following lab assignments from day's 1 through 5: Lab Assignments  1 Environment Setup 2 Build a dynamic Home Page 3 Site Authentication 4 Build Customer Registration 5 Display Top Level Categories 6 Display Product Sub-Categories 7 Display Product List Page 8 Display Product Detail Page 9 ATG Inventory 10 Build “Add to Cart” Functionality 11 Build Shopping Cart 12 Build Checkout Page  13 Build Checkout Review Page 14 Create an Order and Build Order Confirmation Page 15 Implement Slots and Targeters for Personalization 16 Implement Pricing and Promotions 17 Order Fulfillment Back to top Week 2 – Day 6 through 10 Team-based Case Project In the second week of the boot camp training, participants will be asked to join a project team that will select a case project for the team to implement. Teams will be able to choose from four of the most common application types developed and deployed on the ATG platform. They are as follows: Hard goods with physical fulfillment, Soft goods with electronic fulfillment, a Service or subscription case example, a Course/Event registration case example. Team projects will have approximately 160 hours of use cases/stories for each team to build (40 hours per developer). Each day's Use Cases/Stories will build upon the prior day's work, and therefore must be fully completed at the end of each day. Please note that this boot camp intends to simulate real-world project conditions, and as such will likely require the need for project teams to possibly work beyond normal business hours. To promote further collaboration and group learning, each team will be asked to present their work and share the methodologies and solutions that they've applied to their cases at the end of each day. Location: Oracle Reading CVC TPC510 Room: Wraysbury Reading, UK 9:00 AM – 5:00 PM  Registration Fee (10 Days): US $3,375 Please click on the following link to REGISTER or  visit the Oracle ATG Web Commerce 10 Implementation Developer Boot Camp page for more information.

  • Visual Studio 2010 RC and Crystal Reports 2008 Just Works

    I have Crystal Reports 2008. This is the full application, not the Crystal Reports extension embedded into Visual Studio. This morning I pulled a solution with many projects and many crystal report files into Visual Studio 2010 for the first time. This application originated in VS2003, migrated to VS2005/.NET 2.0, migrated again to VS2008 (still .NET 2.0) and now migrated to VS2010 (still .NET 2.0). Wow everything is SO much faster working with this solution in VS2010. It loads up so quickly. It...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Check Your Spelling, Grammar, and Style in Firefox and Chrome

    - by Matthew Guay
    Are you tired of making simple writing mistakes that get past your browser’s spell-check?  Here’s how you can get advanced grammar check and more in Firefox and Chrome with After the Deadline. Microsoft Word has spoiled us with grammar, syntax, and spell checking, but the default spell check in Firefox and Chrome still only does basic checks.  Even webapps like Google Docs don’t check more than basic spelling errors.  However, WordPress.com is an exception; it offers advanced spelling, grammar, and syntax checking with its After the Deadline proofing system.  This helps you keep from making embarrassing mistakes on your blog posts, and now, thanks to a couple free browser plugins, it can help you keep from making these mistakes in any website or webapp. After the Deadline in Google Chrome Add the After the Deadline extension (link below) to Chrome as usual. As soon as it’s installed, you’re ready to start improving your online writing.  To check spelling, grammar, and more, click the ABC button that you’ll now see at the bottom of most text boxes online. After a quick scan, grammar mistakes are highlighted in green, complex expressions and other syntax problems are highlighted in blue, and spelling mistakes are highlighted in red as would be expected.  Click on an underlined word to choose one of its recommended changes or ignore the suggestion. Or, if you want more explanation about what was wrong with that word or phrase, click Explain for more info. And, if you forget to run an After the Deadline scan before submitting a text entry, it will automatically check to make sure you still want to submit it.  Click Cancel to go back and check your writing first.   To change the After the Deadline settings, click its icon in the toolbar and select View Options.  Additionally, if you want to disable it on the site you’re on, you can click Disable on this site directly from the popup. From the settings page, you can choose extra things to check for such as double negatives and redundant phrases, as well as add sites and words to ignore. After the Deadline in Firefox Add the After the Deadline add-on to Firefox (link below) as normal. After the Deadline basically the same in Firefox as it does in Chrome.  Select the ABC icon in the lower right corner of textboxes to check them for problems, and After the Deadline will underline the problems as it did in Chrome.  To view a suggested change in Firefox, right-click on the underlined word and select the recommended change or ignore the suggestion. And, if you forget to check, you’ll see a friendly reminder asking if you’re sure you want to submit your text like it is. You can access the After the Deadline settings in Firefox from the menu bar.  Click Tools, then select AtD Preferences.  In Firefox, the settings are in a options dialog with three tabs, but it includes the same options as the Chrome settings page.  Here you can make After the Deadline as correction-happy as you like.   Conclusion The web has increasingly become an interactive place, and seldom does a day go by that we aren’t entering text in forms and comments that may stay online forever.  Even our insignificant tweets are being archived in the Library of Congress.  After the Deadline can help you make sure that your permanent internet record is as grammatically correct as possible.  Even though it doesn’t catch every problem, and even misses some spelling mistakes, it’s still a great help.

    1,000 blogposts is quite a few, but to die-hard geeks, 1000 isn't the number... 1K is the number, and today is my 1K blogpost! I've been working up to this for at least 11 months. Way back at MIX10, I approached some vendors about an idea I had. A month ago I contacted them and others, and everyone I contacted was very generous and supportive of my idea. My idea was not to run a contest, but blog as normal, and whoever ended up on my 1K post would get some swag... and I set a cut-off at 13 posts. So... blogging normally, I had some submittals, and then ran my normal process to pick up the next posts until I hit a total of 13. To provide a distribution channel for the swag, everyone on the list, please send me your snail mail (T-shirts) and email (licenses) addresses as soon as possible.   I'd like to thank the following generous sponsors for their contributions to my fun (in alphabetic order): and Rachel Hawley for contributing 4 Silverlight control sets First Floor Software and Koen Zwikstra for contributing 13 licenses for Silverlight Spy and Sara Faatz/Jason Beres for contributing 13 licenses for Silverlight Data Visualization controls and Svetla Stoycheva for contributing T-Shirts for everyone on the post and Ina Tontcheva for contributing 13 licenses for RadControls for Silverlight + RadControls for Windows Phone and Charlene Kozlan for contributing 1 combopack standard, 2 DataGrid for Silverlight, and 2 Listbox for Silverlight Standard And now finally...in this Issue: Nigel Sampson, Jeremy Likness, Dan Wahlin, Kunal Chowdhurry, Alex Knight, Wei-Meng Lee, Michael Crump, Jesse Liberty, Peter Kuhn, Michael Washington, Tau Sick, Max Paulousky, Damian Schenkelman Above the Fold: Silverlight: "Demystifying Silverlight Dependency Properties" Dan Wahlin WP7: "Using Windows Phone Gestures as Triggers" Nigel Sampson Expression Blend: "PathListBox: making data look cool" Alex Knight From SilverlightCream.com: Using Windows Phone Gestures as Triggers Nigel Sampson blogged about WP7 Gestures, the Toolkit, and using Gestures as Triggers, and actually makes it looks simple :) Jounce Part 9: Static and Dynamic Module Management Jeremy Likness has episode 9 of his explanation of his MVVM framework, Jounce, up... and a big discussion of Modules and Module Management from a Jounce perspective. Demystifying Silverlight Dependency Properties Dan Wahlin takes a page from one of his teaching opportunities, and shares his knowledge of Dependency Properties with us... beginning with what they are, defining them in code, and demonstrating their use. Customizing Silverlight ChildWindow Style using Blend Kunal Chowdhurry has a great post up about getting your Child Windows to match the look & feel of the rest of youra app... plus a bunch of Blend goodness thrown in. PathListBox: making data look cool File this post by Alex Knight in the 'holy crap' file along with the others in this series! ... just check out that cool Ticker Style Path ListBox at the top of the blog... too cool! Web Access in Windows Phone 7 Apps Wei-Meng Lee has the 3rd part of his series on WP7 development up and in this one is discussing Web Access... I mean *discussing* it... tons of detail, code, and explanation... great post. Prevent your Silverlight XAP file from caching in your browser. Michael Crump helps relieve stress on Silverlight developers everywhere by exploring how to avoid caching of your XAP in the browser... (WPFS) MVVM Light Toolkit: Soup To Nuts Part I Jesse Liberty continues his Windows Phone from Scratch series with a new segment exploring Laurent Bugnion's MVVMLight Toolkit beginning with acquiring and installing the toolkit, then proceeds to discuss linking the View and ViewModel, the ViewModel Locator, and page navigation.

Windows Phone 7 Animated Button Press Michael Washington took exception to button presses that gave no visual feedback and produced a behavior that does just that. Using TweetSharp in a Windows Phone 7 app Tau Sick demonstrates using TweetSharp to put a twitter feed into a WP7 app, as he did in "Hangover Helper"... all the instructions from getting Tweeetshaprt to the code necessary. Bindable Application Bar Extensions for Windows Phone 7 Max Paulousky has a post discussing some real extensions to the ApplicationBar for WP7.. he begins with a bindable application bar by Nicolas Humann that I've missed, probably because his blog is in French... and extends it to allow using DelegateCommand. How to: Load Prism modules packaged in a separate XAP file in an OOB application Damian Schenkelman posts about Prism, AppModules in separate XAPs and running OOB... if you've tried this, you know it's a hassle.. Damian has the solution. Stay in the 'Light!

  • Visual Studio 2010 tip: Cut empty lines

    - by koevoeter
    How many times you wanted to move 2 lines by cut and pasting them, but the line you cut last is actually a blank line and your actual code is removed from the clipboard? Visual Studio 2010 has an option that keeps cutting blank lines from overwriting the clipboard. Go and uncheck this one: Tools » Options » Text Editor » All Languages » General » Apply Cut or Copy commands to blank lines when there is no selection Extra (related) tip The (free) Visual Studio 2010 extension Visual Studio 2010 Pro Power Tools contains (apart from a bunch of other handy features) the commands Edit.MoveLineUp and Edit.MoveLineDown to do whatever they say they do and maps them automatically to keyboard shortcuts Alt+Up & Alt+Down. Resharper (not-free) has similar commands for moving lines, by default mapped to Ctrl+Alt+Shift+Up/Down.

  • First Post

    - by Allan Ritchie
    It has been a while since I've had a blog, but I'm back into the open source dev and decided to get back into things.  I had a blog a few years back when NHibernate was infant (0.8 or something) and I was working with the Wilson ORMapper (www.ormapper.net) at the time.  Anyhow, I'm still working with NHibernate (particularily the exciting v3 alpha 1) and Castle framework. I've also written a .NET ExtDirect stack for which I'll be writing a few articles around due to its flexibility.  I decided to write yet another communication stack because all the implementations I found on the Ext forums were lacking any sort of flexibility.  So stay tuned... I'll be presenting a bunch of the extension points.
