Error using Session in IIS

- by flashnik

After deployment of my website to IIS I'm getting a following error message when trying to access session: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. I access it in Page_Load or PreRender events (I tried both versions). With VS Dev Server it works without a problem. I tried both InProc an SessionState storage, 1 and multiple woker processes. I added a enableSessionState = "true" to my webpage explicitly. Here is part of web.config: <system.web> <globalization culture="ru-RU" uiCulture="ru-RU" /> <compilation debug="true" defaultLanguage="c#"> <assemblies> <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> <add assembly="System.Web.Extensions.Design, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add assembly="System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" /> <add assembly="System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089" /> </assemblies> </compilation> <pages enableEventValidation="false" enableSessionState="true"> <controls> <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> </controls> </pages> <httpHandlers> <remove verb="*" path="*.asmx" /> <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" /> </httpHandlers> <httpModules> <add name="ScriptModule" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" /> <add name="SearchUrlRewriter" type="Synonymizer.SearchUrlRewriter, Synonymizer, Version=1.0.0.0, Culture=neutral" /> <add name="Session" type="System.Web.SessionStateModule" /> </httpModules> <sessionState cookieless="UseCookies" cookieName="My_SessionId" mode="InProc" stateNetworkTimeout="5" /> <customErrors mode="Off" /> </system.web> What else do I need to do to make it work??

iStack for iPad

- by Jonathan

The below image is the current, and hopefully final, look of the front screen, the app will remember which stack site you have chosen so the user will only see this screen the first time, but they can always go back and change it. The red bar is only there when a new site is added (the StackOverflow is just a test as no site has been added since I implemented this) and can be gotten rid of by tapping the X on the right side (which isn't in the screenshot). Each column now has an edit button where the sites can be rearranged and moved from favourites to non favourites and this is persistent between app launches, moving a site in one column moves it in all of them. I've removed site icons in order to put them in properly so they load lazily and theres no UI freezing. Printing Functionality all implemented and working, thanks to systempuntoout's stackprinter.com works with AirPrint, which means this app will be iOS 4.2 minimum. Current features: 3 columns Email link to question, open in safari and copy link actions History for both questions and sites visited In app notification (red bar at the top) when a new site makes it into beta. StackPrinter in the app, without needing safari, and AirPrint functionality. Facebook Intergration Planned: Local Favourites Watching (a list of questions your watching, like short term favourites, with eventually push notifications) Web service to access local favourites and watches on non-iPad devices. Twitter integration. Safari bookmarklet to open question in iStack from safari In app notification for when site progresses from beta to normal. In app notification history

Forking a GPL dual licensed software with business owned copyrights

- by Eric

After receiving some threats of the copyrights holder of a dual licensed software(GPL2 and commercial) to buy the commercial version for projects in production, I am thinking to make a fork. In a case of GPL2 and commercially dual licensed with business owned copyrights software, is forking the GPL2 version an option? Also, is forking a good way to deal with such cases? Background information The software is a web CMS released under 2 versions a GPL2 free open source edition and a commercial edition including technical support and extra functionality. The problem is that now, basing their argumentation on the "distribution" definition of the GPL2, the company holding the copyrights argue that delivering the software and some extensions to a client is considered as a "distribution". And that such a "distribution" falls under the GPL2 obligation to release the custom made extension code. Custom made extensions are mainly designs, templates and very specific functionality. Basically they give me 3 choices: Buying the commercial licensed edition for projects based on the GPL in production, Deleting all the projects in production based on GPL2 version, Releasing all the extensions as GPL2 code. The first 2 options are nothing realistic for finished projects. The third option could be fine, but as most of the extensions are very specific, cleaning the code to make it usable by other users means lot of works and also I am not sure the clients will appreciate to have their website designs and specific functionality released publicly. The copyrights holding company even contacted some clients directly, giving them the "choice". I know that this is a very corporate interpretation of GPL2, and a such action is nothing close to legal, but as an independent developer, I don't want to take the risk to get involved in some long and tiring legal procedures. PS. This question was first asked on Stack Overflow where it felt out of the scope and closed, after reading the present site FAQ, discussing about software licensing seems fine.

ASP.NET application partially reading external configuration

- by Trent

I have an ASP.NET web app and am attempting to reference an external config (using enterprise application blocks configuration) for some of the configuration but it is not entirely working. I previously had all of the configuration info in the web.config (and it was working), but we are wanting to share some of this configuration information between multiple apps. When I put configurationSource tag in the web.config, and read the configuration through the WebConfigurationManager object, it loads some of the external config info (Logging) but not the connectionStrings and not the custom section I created. So its reading it (logging is working), but some dots aren't being connected and my connection strings aren't coming through. Again, it worked when it was all in the web.config. Any idea what needs to change to be able to reference an external configuration source and have it all come through?

Beginner Geek: How to Use Bookmarklets on Any Device

- by Chris Hoffman

Web browser bookmarklets allow you to perform actions on the current page with just a click or tap. They’re a lightweight alternative to browser extensions. They even work on mobile browsers that don’t support traditional extensions. To use bookmarklets, all you need is a web browser that supports bookmarks — that’s it! Bookmarklets Explained Web pages you view in your browser use JavaScript code. That’s why web pages aren’t just static documents anymore — they’re dynamic. A bookmarklet is a normal bookmark with a piece of JavaScript code instead of a web address. When you click or tap the bookmarklet, it will execute the JavaScript code on the current page instead of loading a different page, as most bookmarks do. Bookmarklets can be used to do something to a web page with a single click. For example, you’ll find bookmarklets associated with web services like Twitter, Facebook, Google+, LinkedIn, Pocket, and LastPass. When you click the bookmarklet, it will run code that lets you easily share the current page with that service. Bookmarklets don’t just have to be associated with web services. A bookmarklet you click could modify the appearance of the page, stripping away most of the junk and giving you a clean “reading mode.” It could alter fonts, remove images, or insert other content. It can access anything the web page could access. For example, you could use a bookmarklet to reveal a password that just appears as ******* on the page. Unlike browser extensions, bookmarklets don’t run in the background and bog down your browser. They don’t do anything at all until you click them. Because they just use the standard bookmark system, they can also be used in mobile browsers where you couldn’t run extensions. For example, you could install the Pocket bookmarklet in Safari on an iPad and get an “Add to Pocket” option in Safari. Safari doesn’t offer browsing extensions and Apple’s iOS doesn’t offer a “Share” feature like Android and Windows 8 do, so this is the only way to get this direct integration. You could even use the LastPass bookmarklets in Safari on an iPad to integrate LastPass with the Safari web browser. Where to Find Bookmarklets If you’re looking for a bookmarklet for a particular service, you’ll generally find the bookmarklet on that service’s site. Websites like Twitter, Facebook, and Pocket host pages where they provide bookmarklets along with browser extensions. Bookmarklets aren’t like programs. They’re really just a piece of text that you can put in a bookmarklet, so you don’t have to download them a specific site. You can get them from practically anywhere — installing them just involves copying a bit of text off of a web page. For example, you can just search the web for “reveal password bookmarklet” if you wanted a bookmarklet that will reveal passwords. We’ve covered many of the must-have bookmarklets — and our readers have chimed in too — so take a look at our lists for more examples. How to Install a Bookmarklet Bookmarklets are simple to install. When you hover over a bookmarklet on a web page, you’ll see its address begins with “javascript:”. If you have your web browser’s bookmark or favorites toolbar visible, the easiest way to install a bookmarklet is with drag-and-drop. Press Ctrl+Shift+B to show your bookmarks toolbar if you’re using Chrome or Internet Explorer. In Firefox, right-click the toolbar and click Bookmarks Toolbar. Just drag and drop this link to your bookmark toolbar. The bookmarklet is now installed. You can also install bookmarklets manually. Select the bookmarklet’s code and copy it to your clipboard. If the bookmarklet is a link, right-click or long-press the link and copy its address to your clipboard. Open your browser’s bookmarks manager, add a bookmark, and paste the JavaScript code directly into the address box. Give your bookmarklet a name and save it. How to Use a Bookmarklet Bookmarklets are easiest to use if you have your browser’s bookmarks toolbar enabled. Just click the bookmarklet and your browser will run it on the current page. If you don’t have a bookmarks toolbar — such as on Safari on an iPad or another mobile browser — just open your browser’s bookmarks pane and tap or click the bookmark. In mobile Chrome, you’ll need to launch the bookmarklet from the location bar. Open the web page you want to run the bookmarklet on, tap your location bar, and start searching for the name of the bookmarklet. Tap the bookmarklet’s name to run it on the current page. Note that the bookmarklet only appears here because we have it saved as a bookmark in Chrome. You’ll need to add the bookmarklet to your browser’s bookmarks before you can use it in this way. The location bar approach may also be necessary in other browsers. The trick is loading the bookmark so that it will be associated with your current tab. You can’t just open your bookmarks in a separate browser tab and run the bookmarklet from there — it will run on that other browser tab. Bookmarklets are powerful and flexible. While they’re not as flashy as browser extensions, they’re much more lightweight and allow you to get extension-like features in more limited mobile browsers.

C# Extension Methods - To Extend or Not To Extend...

- by James Michael Hare

I've been thinking a lot about extension methods lately, and I must admit I both love them and hate them. They are a lot like sugar, they taste so nice and sweet, but they'll rot your teeth if you eat them too much. I can't deny that they aren't useful and very handy. One of the major components of the Shared Component library where I work is a set of useful extension methods. But, I also can't deny that they tend to be overused and abused to willy-nilly extend every living type. So what constitutes a good extension method? Obviously, you can write an extension method for nearly anything whether it is a good idea or not. Many times, in fact, an idea seems like a good extension method but in retrospect really doesn't fit. So what's the litmus test? To me, an extension method should be like in the movies when a person runs into their twin, separated at birth. You just know you're related. Obviously, that's hard to quantify, so let's try to put a few rules-of-thumb around them. A good extension method should: Apply to any possible instance of the type it extends. Simplify logic and improve readability/maintainability. Apply to the most specific type or interface applicable. Be isolated in a namespace so that it does not pollute IntelliSense. So let's look at a few examples in relation to these rules. The first rule, to me, is the most important of all. Once again, it bears repeating, a good extension method should apply to all possible instances of the type it extends. It should feel like the long lost relative that should have been included in the original class but somehow was missing from the family tree. Take this nifty little int extension, I saw this once in a blog and at first I really thought it was pretty cool, but then I started noticing a code smell I couldn't quite put my finger on. So let's look: public static class IntExtensinos { public static int Seconds(int num) { return num * 1000; } public static int Minutes(int num) { return num * 60000; } } This is so you could do things like: ... Thread.Sleep(5.Seconds()); ... proxy.Timeout = 1.Minutes(); ... Awww, you say, that's cute! Well, that's the problem, it's kitschy and it doesn't always apply (and incidentally you could achieve the same thing with TimeStamp.FromSeconds(5)). It's syntactical candy that looks cool, but tends to rot and pollute the code. It would allow things like: total += numberOfTodaysOrders.Seconds(); which makes no sense and should never be allowed. The problem is you're applying an extension method to a logical domain, not a type domain. That is, the extension method Seconds() doesn't really apply to ALL ints, it applies to ints that are representative of time that you want to convert to milliseconds. Do you see what I mean? The two problems, in a nutshell, are that a) Seconds() called off a non-time value makes no sense and b) calling Seconds() off something to pass to something that does not take milliseconds will be off by a factor of 1000 or worse. Thus, in my mind, you should only ever have an extension method that applies to the whole domain of that type. For example, this is one of my personal favorites: public static bool IsBetween<T>(this T value, T low, T high) where T : IComparable<T> { return value.CompareTo(low) >= 0 && value.CompareTo(high) <= 0; } This allows you to check if any IComparable<T> is within an upper and lower bound. Think of how many times you type something like: if (response.Employee.Address.YearsAt >= 2 && response.Employee.Address.YearsAt <= 10) { ... } Now, you can instead type: if(response.Employee.Address.YearsAt.IsBetween(2, 10)) { ... } Note that this applies to all IComparable<T> -- that's ints, chars, strings, DateTime, etc -- and does not depend on any logical domain. In addition, it satisfies the second point and actually makes the code more readable and maintainable. Let's look at the third point. In it we said that an extension method should fit the most specific interface or type possible. Now, I'm not saying if you have something that applies to enumerables, you create an extension for List, Array, Dictionary, etc (though you may have reasons for doing so), but that you should beware of making things TOO general. For example, let's say we had an extension method like this: public static T ConvertTo<T>(this object value) { return (T)Convert.ChangeType(value, typeof(T)); } This lets you do more fluent conversions like: double d = "5.0".ConvertTo<double>(); However, if you dig into Reflector (LOVE that tool) you will see that if the type you are calling on does not implement IConvertible, what you convert to MUST be the exact type or it will throw an InvalidCastException. Now this may or may not be what you want in this situation, and I leave that up to you. Things like this would fail: object value = new Employee(); ... // class cast exception because typeof(IEmployee) != typeof(Employee) IEmployee emp = value.ConvertTo<IEmployee>(); Yes, that's a downfall of working with Convertible in general, but if you wanted your fluent interface to be more type-safe so that ConvertTo were only callable on IConvertibles (and let casting be a manual task), you could easily make it: public static T ConvertTo<T>(this IConvertible value) { return (T)Convert.ChangeType(value, typeof(T)); } This is what I mean by choosing the best type to extend. Consider that if we used the previous (object) version, every time we typed a dot ('.') on an instance we'd pull up ConvertTo() whether it was applicable or not. By filtering our extension method down to only valid types (those that implement IConvertible) we greatly reduce our IntelliSense pollution and apply a good level of compile-time correctness. Now my fourth rule is just my general rule-of-thumb. Obviously, you can make extension methods as in-your-face as you want. I included all mine in my work libraries in its own sub-namespace, something akin to: namespace Shared.Core.Extensions { ... } This is in a library called Shared.Core, so just referencing the Core library doesn't pollute your IntelliSense, you have to actually do a using on Shared.Core.Extensions to bring the methods in. This is very similar to the way Microsoft puts its extension methods in System.Linq. This way, if you want 'em, you use the appropriate namespace. If you don't want 'em, they won't pollute your namespace. To really make this work, however, that namespace should only include extension methods and subordinate types those extensions themselves may use. If you plant other useful classes in those namespaces, once a user includes it, they get all the extensions too. Also, just as a personal preference, extension methods that aren't simply syntactical shortcuts, I like to put in a static utility class and then have extension methods for syntactical candy. For instance, I think it imaginable that any object could be converted to XML: namespace Shared.Core { // A collection of XML Utility classes public static class XmlUtility { ... // Serialize an object into an xml string public static string ToXml(object input) { var xs = new XmlSerializer(input.GetType()); // use new UTF8Encoding here, not Encoding.UTF8. The later includes // the BOM which screws up subsequent reads, the former does not. using (var memoryStream = new MemoryStream()) using (var xmlTextWriter = new XmlTextWriter(memoryStream, new UTF8Encoding())) { xs.Serialize(xmlTextWriter, input); return Encoding.UTF8.GetString(memoryStream.ToArray()); } } ... } } I also wanted to be able to call this from an object like: value.ToXml(); But here's the problem, if i made this an extension method from the start with that one little keyword "this", it would pop into IntelliSense for all objects which could be very polluting. Instead, I put the logic into a utility class so that users have the choice of whether or not they want to use it as just a class and not pollute IntelliSense, then in my extensions namespace, I add the syntactical candy: namespace Shared.Core.Extensions { public static class XmlExtensions { public static string ToXml(this object value) { return XmlUtility.ToXml(value); } } } So now it's the best of both worlds. On one hand, they can use the utility class if they don't want to pollute IntelliSense, and on the other hand they can include the Extensions namespace and use as an extension if they want. The neat thing is it also adheres to the Single Responsibility Principle. The XmlUtility is responsible for converting objects to XML, and the XmlExtensions is responsible for extending object's interface for ToXml().

Adding multiple data importers support to web applications

- by DigiMortal

I’m building web application for customer and there is requirement that users must be able to import data in different formats. Today we will support XLSX and ODF as import formats and some other formats are waiting. I wanted to be able to add new importers on the fly so I don’t have to deploy web application again when I add new importer or change some existing one. In this posting I will show you how to build generic importers support to your web application. Importer interface All importers we use must have something in common so we can easily detect them. To keep things simple I will use interface here. public interface IMyImporter { string[] SupportedFileExtensions { get; } ImportResult Import(Stream fileStream, string fileExtension); } Our interface has the following members: SupportedFileExtensions – string array of file extensions that importer supports. This property helps us find out what import formats are available and which importer to use with given format. Import – method that does the actual importing work. Besides file we give in as stream we also give file extension so importer can decide how to handle the file. It is enough to get started. When building real importers I am sure you will switch over to abstract base class. Importer class Here is sample importer that imports data from Excel and Word documents. Importer class with no implementation details looks like this: public class MyOpenXmlImporter : IMyImporter { public string[] SupportedFileExtensions { get { return new[] { "xlsx", "docx" }; } } public ImportResult Import(Stream fileStream, string extension) { // ... } } Finding supported import formats in web application Now we have importers created and it’s time to add them to web application. Usually we have one page or ASP.NET MVC controller where we need importers. To this page or controller we add the following method that uses reflection to find all classes that implement our IMyImporter interface. private static string[] GetImporterFileExtensions() { var types = from a in AppDomain.CurrentDomain.GetAssemblies() from t in a.GetTypes() where t.GetInterfaces().Contains(typeof(IMyImporter)) select t; var extensions = new Collection<string>(); foreach (var type in types) { var instance = (IMyImporter)type.InvokeMember(null, BindingFlags.CreateInstance, null, null, null); foreach (var extension in instance.SupportedFileExtensions) { if (extensions.Contains(extension)) continue; extensions.Add(extension); } } return extensions.ToArray(); } This code doesn’t look nice and is far from optimal but it works for us now. It is possible to improve performance of web application if we cache extensions and their corresponding types to some static dictionary. We have to fill it only once because our application is restarted when something changes in bin folder. Finding importer by extension When user uploads file we need to detect the extension of file and find the importer that supports given extension. We add another method to our page or controller that uses reflection to return us importer instance or null if extension is not supported. private static IMyImporter GetImporterForExtension(string extensionToFind) { var types = from a in AppDomain.CurrentDomain.GetAssemblies() from t in a.GetTypes() where t.GetInterfaces().Contains(typeof(IMyImporter)) select t; foreach (var type in types) { var instance = (IMyImporter)type.InvokeMember(null, BindingFlags.CreateInstance, null, null, null); if (instance.SupportedFileExtensions.Contains(extensionToFind)) { return instance; } } return null; } Here is example ASP.NET MVC controller action that accepts uploaded file, finds importer that can handle file and imports data. Again, this is sample code I kept minimal to better illustrate how things work. public ActionResult Import(MyImporterModel model) { var file = Request.Files[0]; var extension = Path.GetExtension(file.FileName).ToLower(); var importer = GetImporterForExtension(extension.Substring(1)); var result = importer.Import(file.InputStream, extension); if (result.Errors.Count > 0) { foreach (var error in result.Errors) ModelState.AddModelError("file", error); return Import(); } return RedirectToAction("Index"); } Conclusion That’s it. Using couple of ugly methods and one simple interface we were able to add importers support to our web application. Example code here is not perfect but it works. It is possible to cache mappings between file extensions and importer types to some static variable because changing of these mappings means that something is changed in bin folder of web application and web application is restarted in this case anyway.

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.

Looking for literature about graphics pipeline optimization

- by zacharmarz

I am looking for some books, articles or tutorials about graphics architecture and graphics pipeline optimizations. It shouldn't be too old (2008 or newer) - the newer, the better. I have found something in [Optimising the Graphics Pipeline, NVIDIA, Koji Ashida] - too old, [Real-time rendering, Akenine Moller], [OpenGL Bindless Extensions, NVIDIA, Jeff Bolz], [Efficient multifragment effects on graphics processing units, Louis Frederic Bavoil] and some internet discussions. But there is not too much information and I want to read more. It should contain something about application, driver, memory and shader units communication and data transfers. About vertices and attributes. Also pre and post T&L cache (if they still exist in nowadays architectures) etc. I don't need anything about textures, frame buffers and rasterization. It can also be about OpenGL (not about DirecX) and optimizing extensions (not old extensions like VBOs, but newer like vertex_buffer_unified_memory).

How to approach iOS web clip app "download"?

- by Ryan

We have our main site at: http://mysite.com which we don't want to alter. Then we have our web clip app at: http://mysite.com/app/ If someone visits the app URL in normal Safari then the Safari UI will still display. But if the user adds the app URL to their home screen, and then they tap that icon they will launch the app URL without the Safari UI as intended. My question is how do you go about getting the user to use the web clip app from their home screen when they start from mysite.com? What I'm thinking is that we have a link on mysite.com that points to mysite.com/app/. Then when they click that /app/ link they'll go to the app but it won't be in "app mode". Can I detect that it's not in app mode and display a message like "add this page to your home screen to use the app"? And then when they do visit in app mode obviously just let the app run.

Enable Multi-Column Google Searches with a User Script

- by Asian Angel

Are you wanting to improve the search results view at Google and make better use of the webpage space? With a little user script magic you can make those search results look and fit better in your favorite browser. Note: This user script may conflict with the AutoPager extension if you have it installed in your favorite browser. Before Here is the standard single column view of search results at Google. Not too bad but the available space could certainly be better utilized. Note: For the purposes of our example we are using Google Chrome but this user script can be easily added to other browsers. After If you have never installed a user script in Chrome before it is just as simple as the regular extensions at the official Google website. Here you can see the details for the user script we are installing. Notice that you can view the source code if desired. To add the user script to Chrome click on “Install”. Once you start the install process you will see an intermediary message asking if you wish to continue in the lower left corner of your browser. Click “Continue” to move to the next step in the install process. From this point on the install process is practically identical to the official extensions. You can see the final confirmation window here…click “Install” to finish adding the user script to Chrome. As with regular extensions you will see a post-install message in the upper right corner. So, what does a user script look like in the “Extensions Page”? You can see the user script entry here…outside of an icon it looks rather identical to a normal extension. After refreshing the search page shown above we now have two columns of search results (default setting). This looks much much better than a single column view and there is little to no page scrolling required now. To switch to a three column view simply use the keyboard shortcut “Alt + 3”. To return to a single column view use “Alt + 1” and for the default two column view use “Alt + 2”. Three keyboard shortcuts for three different views…definitely a good thing. Note: On our test system we needed to use the number keys at the top of our keyboard to switch views…this is most likely the result of unique settings on our test system. Conclusion If you are wanting a better viewing experience when conducting searches at Google then this user script will make a very nice addition to your favorite browser. For those using Firefox you can add user scripts with the Greasemonkey & Stylish extensions. Using Opera Browser? See our how-to for adding user scripts to Opera here.

My collection of favourite TFS utilities

- by Aaron Kowall

So, you’re in charge of your company or team’s Team Foundation Server. Wish it was easier to manage, administer, extend? Well, here are a few utilities that I highly recommend looking at. I’ve recently had need to rebuild my laptop and upgrade my local TFS environment to TFS 2012 Update 1. This gave me cause to enumerate some of the utilities I like to have on hand. One of the reasons I love to use TFS on projects is that it’s basically a complete ALM toolkit. Everything from Task Management, Version Control, Build Management, Test Management, Metrics and Reporting are all there ‘in the box’. However, no matter how complete a product set it, there are always ways to make it better. Here are a list of utilities and libraries that are pretty generally useful. this is not intended to be an exhaustive list of TFS extensions but rather a set that I recommend you look at. There are many more out there that may be applicable in one scenario or another. This set of tools should work with TFS 2012 or 2010 if you grab the right version. Most of these tools (and more) are available from the Visual Studio Gallery or CodePlex. General TFS Power Tools – This is ‘the’ collection of utilities and extensions delivered by the Product Group. Highly recommended from here are the Best Practice Analyzer for ensuring your TFS implementation is healthy and the Team Foundation Server Backups to ensure your TFS databases are backed up correctly. TFS Administrators Toolkit – helps make updates to work item types and reports across many team projects. Also provides visibility of disk usage by finding large files in version control or test attachments to assist in managing storage utilization. Version Control Git-TF - a set of cross-platform, command line tools that facilitate sharing of changes between TFS and Git. These tools allow a developer to use a local Git repository, and configure it to share changes with a TFS server. Great for all Git lovers who must integrate into a TFS repository. Testing TFS 2012 Tester Power Tool – A utility for bulk copying test cases which assists in an approach for managing test cases across multiple releases. A little plug that this utility was written and maintained by Anna Russo of Imaginet where I also work. Test Scribe - A documentation power tool designed to construct documents directly from the TFS for test plan and test run artifacts for the purpose of discussion, reporting etc. Reporting Community TFS Report Extensions - a single repository of SQL Server Reporting Services report for Team Foundation 2010 (and above). Check out the Test Plan Status report by Imaginet’s Steve St. Jean. Very valuable for your test managers. Builds TFS Build Manager – A great utility if you are build manager over a complex build environment with many TFS build definitions. Community TFS Build Extensions – contains many custom build activities. Current release binaries are for TFS 2010 but many of the activities can be recompiled for use with TFS 2012. While compiling this list, I was surprised by the number of TFS utilities and extensions I no longer use/need in TFS 2012 because of the great work by the TFS team addressing many gaps since the 2010 release. Are there any utilities you depend on that I’ve missed? I’d love to hear about them in the comments!

How to make a Custom Data Generator for SQL XML DataType.

- by Keith Sirmons

Howdy, I am using Visual Studio 2010 and am playing around with the Database Projects. I am creating a DataGenerationPlan to insert data into a simple table, in which one of the column datatypes is XML. Out of the box, the generation plan uses the Regular Expression generator and generates something like this : HGcSv9wa7yM44T9x5oFT4pmBkEmv62lJ7OyAmCnL6yqXC2X.......... I am looking at creating a custom data Generator for this data type and have followed this site for the basics: http://msdn.microsoft.com/en-us/library/aa833244.aspx This example works if I am creating a string datatype and using it for a nvarchar datatype. What do I need to change to hook this Generator to the XML Datatype? Below are my code files. The string property works for nvarchar. The XElement property does not work for the xml datatype, and the RecordXMLDataGenerator is not listed as an option in the Generator column for the generation plan. CustomDataGenerators: using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Data.Schema.Tools.DataGenerator; using Microsoft.Data.Schema.Extensibility; using Microsoft.Data.Schema; using Microsoft.Data.Schema.Sql; using System.Xml.Linq; namespace CustomDataGenerators { [DatabaseSchemaProviderCompatibility(typeof(SqlDatabaseSchemaProvider))] public class RecordXMLDataGenerator : Generator { private XElement _RecordData; [Output(Description = "Generates string of XML Data for the Record.", Name = "RecordDataString")] public string RecordDataString { get { return _RecordData.ToString(SaveOptions.None); } } [Output(Description = "Generates XML Data for the Record.", Name = "RecordData")] public XElement RecordData { get { return _RecordData; } } protected override void OnGenerateNextValues() { base.OnGenerateNextValues(); XElement element = new XElement("Root", new XElement("Children1", 1), new XElement("Children6", 6) ); _RecordData = element; } } } XML Extensions File: <?xml version="1.0" encoding="utf-8" ?> <extensions assembly="" version="1" xmlns="urn:Microsoft.Data.Schema.Extensions" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:Microsoft.Data.Schema.Extensions Microsoft.Data.Schema.Extensions.xsd"> <extension type="CustomDataGenerators.RecordXMLDataGenerator" assembly="CustomDataGenerators, Version=1.0.0.0, Culture=neutral, PublicKeyToken=xxxxxxxxxxxx" enabled="true"/> </extensions> Table.sql: CREATE TABLE [dbo].[Record] ( id int IDENTITY (1,1) NOT NULL, recordData xml NULL, userId int NULL, test nvarchar(max) NULL, rowver rowversion NULL, CONSTRAINT pk_RecordID PRIMARY KEY (id) )

Manually updating FF Add-ons

- by cpp_fanatic

My application installs my Firefox add-on (by copying an my.xpi to [FF_inst_dir]\extensions). This application interact with my FF add-on. This application periodically has updates (.xpi with new version). When my application is updating it does next: Remove folder and content [FF_inst_dir]\extensions\MyExtension Copy new my.xpi to [FF_inst_dir]\extensions However, when I restart FF I see: FF ask me about install add-on. I agree. FF remove my.xpi (it's ok) FF remove folder and content [FF_inst_dir]\extensions\MyExtension I think that FF try to remove old plugin. Thus, I havn't installed plugin. How it can be installed correct?

iPhone TabBar selection cancelling

- by Chris Schnyder

I am developing an iPhone app that displays several views, all acessed via Tab Bar items. However I need to add an additional item to the Tab Bar that simply launches a URL in Safari. I've accomplished this by adding an empty placeholder view to the TabBar and returning FALSE from shouldSelectViewController when the this view's tabBarItem is clicked on, and launching Safari at the same time. That code is: - (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController { if([[viewController tabBarItem] title] == "Website"){ //... launch Safari return FALSE; } else { return TRUE; } } PROBLEM: If the TabBar has too many items, and this "Safari Launch" tab is pushed off to the "More" navigation controller, I lose the capability to intercept the event and prevent the view from loading when clicked. Any suggested tips?

How to macro-ify ant targets?

- by Jonas Byström

I want to be able to have different targets doing nearly the same thing, as so: ant build <- this would be a normal (default) build ant safari <- building the safari target. The targets look like this: <target name="build" depends="javac" description="GWT compile to JavaScript"> <java failonerror="true" fork="true" classname="com.google.gwt.dev.Compiler"> <classpath> <pathelement location="src"/> <path refid="project.class.path"/> </classpath> <jvmarg value="-Xmx256M"/> <arg value="${lhs.target}"/> </java> </target> <target name="safari" depends="javac" description="GWT compile to Safari/JavaScript"> <java failonerror="true" fork="true" classname="com.google.gwt.dev.Compiler"> <classpath> <pathelement location="src"/> <path refid="project.class.path"/> </classpath> <jvmarg value="-Xmx256M"/> <arg value="${lhs.safari.target}"/> </java> </target> (Nevermind the first thought that strikes: throw out ant! That's not an option just yet.) I tried using macrodef, but got a strange error message (even though the message didn't imply it, it think it had to do with putting a target in sequential). I don't want to do ant -Dwhatever=nevermind. Any ideas?

How to setup custom DNS with Azure Websites Preview?

- by husainnz

I created a new Azure Website, using Umbraco as the CMS. I got a page up and going, and I already have a .co.nz domain with www.domains4less.com. There's a whole lot of stuff on the internet about pointing URLs to Azure, but that seems to be more of a redirection service than anything (i.e. my URLs still use azurewebsites.net once I land on my site). Has anybody had any luck getting it to go? Here's the error I get when I try adding the DNS entry to Azure (I'm in reserved mode, reemdairy is the name of the website): There was an error processing your request.
