• Displaying JSON in your Browser

  - by Rick Strahl

  Do you work with AJAX requests a lot and need to quickly check URLs for JSON results? Then you probably know that it’s a fairly big hassle to examine JSON results directly in the browser. Yes, you can use FireBug or Fiddler which work pretty well for actual AJAX requests, but if you just fire off a URL for quick testing in the browser you usually get hit by the Save As dialog and the download manager, followed by having to open the saved document in a text editor in FireFox. Enter JSONView which allows you to simply display JSON results directly in the browser. For example, imagine I have a URL like this: http://localhost/westwindwebtoolkitweb/RestService.ashx?Method=ReturnObject&format=json&Name1=Rick&Name2=John&date=12/30/2010 typed directly into the browser and that that returns a complex JSON object. With JSONView the result looks like this: No fuss, no muss. It just works. Here the result is an array of Person objects that contain additional address child objects displayed right in the browser. JSONView basically adds content type checking for application/json results and when it finds a JSON result takes over the rendering and formats the display in the browser. Note that it re-formats the raw JSON as well for a nicer display view along with collapsible regions for objects. You can still use View Source to see the raw JSON string returned. For me this is a huge time-saver. As I work with AJAX result data using GET and REST style URLs quite a bit it’s a big timesaver. To quickly and easily display JSON is a key feature in my development day and JSONView for all its simplicity fits that bill for me. If you’re doing AJAX development and you often review URL based JSON results do yourself a favor and pick up a copy of JSONView. Other Browsers JSONView works only with FireFox – what about other browsers? Chrome Chrome actually displays raw JSON responses as plain text without any plug-ins. There’s no plug-in or configuration needed, it just works, although you won’t get any fancy formatting. [updated from comments] There’s also a port of JSONView available for Chrome from here: https://chrome.google.com/webstore/detail/chklaanhfefbnpoihckbnefhakgolnmc It looks like it works just about the same as the JSONView plug-in for FireFox. Thanks for all that pointed this out… Internet Explorer Internet Explorer probably has the worst response to JSON encoded content: It displays an error page as it apparently tries to render JSON as XML: Yeah that seems real smart – rendering JSON as an XML document. WTF? To get at the actual JSON output, you can use View Source. To get IE to display JSON directly as text you can add a Mime type mapping in the registry:   Create a new application/json key in: HKEY_CLASSES_ROOT\MIME\Database\ContentType\application/json Add a string value of CLSID with a value of {25336920-03F9-11cf-8FD0-00AA00686F13} Add a DWORD value of Encoding with a value of 80000 I can’t take credit for this tip – found it here first on Sky Sander’s Blog. Note that the CLSID can be used for just about any type of text data you want to display as plain text in the IE. It’s the in-place display mechanism and it should work for most text content. For example it might also be useful for looking at CSS and JS files inside of the browser instead of downloading those documents as well. © Rick Strahl, West Wind Technologies, 2005-2011Posted in ASP.NET  AJAX

• Visual Studio 2010 Beta 2 Startup Failures

  - by Rick Strahl

  I’ve been working with VS 2010 Beta 2 for a while now and while it works Ok most of the time it seems the environment is very, very fragile when it comes to crashes and installed packages. Specifically I’ve been working just fine for days, then when VS 2010 crashes it will not re-start. Instead I get the good old Application cannot start dialog: Other failures I’ve seen bring forth other just as useful dialogs with information overload like Operation cannot be performed which for me specifically happens when trying to compile any project. After a bit of digging around and a post to Microsoft Connect the solution boils down to resetting the VS.NET environment. The Application Cannot Start issue stems from a package load failure of some sort, so the work around for this is typically: c:\program files\Visual Studio 2010\Common7\IDE\devenv.exe /ResetSkipPkgs In most cases that should do the trick. If it doesn’t and the error doesn’t go away the more drastic: c:\program files\Visual Studio 2010\Common7\IDE\devenv.exe /ResetSettings is required which resets all settings in VS to its installation defaults. Between these two I’ve always been able to get VS to startup and run properly. BTW it’s handy to keep a list of command line options for Visual Studio around: http://msdn.microsoft.com/en-us/library/xee0c8y7%28VS.100%29.aspx Note that the /? option in VS 2010 doesn’t display all the options available but rather displays the ‘demo version’ message instead, so the above should be helpful. Also note that unless you install Visual C++ the Visual Studio Command Prompt icon is not automatically installed so you may have to navigate manually to the appropriate folder above. Cannot Build Failures If you get the Cannot compile error dialog, there is another thing that have worked for me: Change your project build target from Debug to Release (or whatever – just change it) and compile again. If that doesn’t work doing the reset steps above will do it for me. It appears this failure comes from some sort of interference of other versions of Visual Studio installed on the system and running another version first. Resetting the build target explicitly seems to reset the build providers to a normalized state so that things work in many cases. But not all. Worst case – resetting settings will do it. The bottom line for working in VS 2010 has been – don’t get too attached to your custom settings as they will get blown away quite a bit. I’ve probably been through 20 or more of these VS resets although I’ve been working with it quite a bit on an internal project. It’s kind of frustrating to see this kind of high level instability in a Beta 2 product which is supposedly the last public beta they will put out. On the other hand this beta has been otherwise rather stable and performance is roughly equivalent to VS 2008. Although I mention the crash above – crashes I’ve seen have been relatively rare and no more frequent than in VS 2008 it seems. Given the drastic UI changes in VS 2010 (using WPF for the shell and editor) I’m actually impressed that the product is as stable as it is at this point. Also I was seriously worried about text quality going to a WPF model, but thankfully WPF 4.0 addresses the blurry text issue with native font rendering to render text on non-cleartype enabled systems crisply. Anyway I hope that these notes are helpful to some of you playing around with the beta and running into problems. Hopefully you won’t need them :-}© Rick Strahl, West Wind Technologies, 2005-2010

• Using VLOOKUP in Excel

  - by Mark Virtue

  VLOOKUP is one of Excel’s most useful functions, and it’s also one of the least understood.  In this article, we demystify VLOOKUP by way of a real-life example.  We’ll create a usable Invoice Template for a fictitious company. So what is VLOOKUP?  Well, of course it’s an Excel function.  This article will assume that the reader already has a passing understanding of Excel functions, and can use basic functions such as SUM, AVERAGE, and TODAY.  In its most common usage, VLOOKUP is a database function, meaning that it works with database tables – or more simply, lists of things in an Excel worksheet.  What sort of things?   Well, any sort of thing.  You may have a worksheet that contains a list of employees, or products, or customers, or CDs in your CD collection, or stars in the night sky.  It doesn’t really matter. Here’s an example of a list, or database.  In this case it’s a list of products that our fictitious company sells: Usually lists like this have some sort of unique identifier for each item in the list.  In this case, the unique identifier is in the “Item Code” column.  Note:  For the VLOOKUP function to work with a database/list, that list must have a column containing the unique identifier (or “key”, or “ID”), and that column must be the first column in the table.  Our sample database above satisfies this criterion. The hardest part of using VLOOKUP is understanding exactly what it’s for.  So let’s see if we can get that clear first: VLOOKUP retrieves information from a database/list based on a supplied instance of the unique identifier. Put another way, if you put the VLOOKUP function into a cell and pass it one of the unique identifiers from your database, it will return you one of the pieces of information associated with that unique identifier.  In the example above, you would pass VLOOKUP an item code, and it would return to you either the corresponding item’s description, its price, or its availability (its “In stock” quantity).  Which of these pieces of information will it pass you back?  Well, you get to decide this when you’re creating the formula. If all you need is one piece of information from the database, it would be a lot of trouble to go to to construct a formula with a VLOOKUP function in it.  Typically you would use this sort of functionality in a reusable spreadsheet, such as a template.  Each time someone enters a valid item code, the system would retrieve all the necessary information about the corresponding item. Let’s create an example of this:  An Invoice Template that we can reuse over and over in our fictitious company. First we start Excel… …and we create ourselves a blank invoice: This is how it’s going to work:  The person using the invoice template will fill in a series of item codes in column “A”, and the system will retrieve each item’s description and price, which will be used to calculate the line total for each item (assuming we enter a valid quantity). For the purposes of keeping this example simple, we will locate the product database on a separate sheet in the same workbook: In reality, it’s more likely that the product database would be located in a separate workbook.  It makes little difference to the VLOOKUP function, which doesn’t really care if the database is located on the same sheet, a different sheet, or a completely different workbook. In order to test the VLOOKUP formula we’re about to write, we first enter a valid item code into cell A11: Next, we move the active cell to the cell in which we want information retrieved from the database by VLOOKUP to be stored.  Interestingly, this is the step that most people get wrong.  To explain further:  We are about to create a VLOOKUP formula that will retrieve the description that corresponds to the item code in cell A11.  Where do we want this description put when we get it?  In cell B11, of course.  So that’s where we write the VLOOKUP formula – in cell B11. Select cell B11: We need to locate the list of all available functions that Excel has to offer, so that we can choose VLOOKUP and get some assistance in completing the formula.  This is found by first clicking the Formulas tab, and then clicking Insert Function:   A box appears that allows us to select any of the functions available in Excel.  To find the one we’re looking for, we could type a search term like “lookup” (because the function we’re interested in is a lookup function).  The system would return us a list of all lookup-related functions in Excel.  VLOOKUP is the second one in the list.  Select it an click OK… The Function Arguments box appears, prompting us for all the arguments (or parameters) needed in order to complete the VLOOKUP function.  You can think of this box as the function is asking us the following questions: What unique identifier are you looking up in the database? Where is the database? Which piece of information from the database, associated with the unique identifier, do you wish to have retrieved for you? The first three arguments are shown in bold, indicating that they are mandatory arguments (the VLOOKUP function is incomplete without them and will not return a valid value).  The fourth argument is not bold, meaning that it’s optional:   We will complete the arguments in order, top to bottom. The first argument we need to complete is the Lookup_value argument.  The function needs us to tell it where to find the unique identifier (the item code in this case) that it should be retuning the description of.  We must select the item code we entered earlier (in A11). Click on the selector icon to the right of the first argument: Then click once on the cell containing the item code (A11), and press Enter: The value of “A11” is inserted into the first argument. Now we need to enter a value for the Table_array argument.  In other words, we need to tell VLOOKUP where to find the database/list.  Click on the selector icon next to the second argument: Now locate the database/list and select the entire list – not including the header line.  The database is located on a separate worksheet, so we first click on that worksheet tab: Next we select the entire database, not including the header line: …and press Enter.  The range of cells that represents the database (in this case “’Product Database’!A2:D7”) is entered automatically for us into the second argument. Now we need to enter the third argument, Col_index_num.  We use this argument to specify to VLOOKUP which piece of information from the database, associate with our item code in A11, we wish to have returned to us.  In this particular example, we wish to have the item’s description returned to us.  If you look on the database worksheet, you’ll notice that the “Description” column is the second column in the database.  This means that we must enter a value of “2” into the Col_index_num box: It is important to note that that we are not entering a “2” here because the “Description” column is in the B column on that worksheet.  If the database happened to start in column K of the worksheet, we would still enter a “2” in this field. Finally, we need to decide whether to enter a value into the final VLOOKUP argument, Range_lookup.  This argument requires either a true or false value, or it should be left blank.  When using VLOOKUP with databases (as is true 90% of the time), then the way to decide what to put in this argument can be thought of as follows: If the first column of the database (the column that contains the unique identifiers) is sorted alphabetically/numerically in ascending order, then it’s possible to enter a value of true into this argument, or leave it blank. If the first column of the database is not sorted, or it’s sorted in descending order, then you must enter a value of false into this argument As the first column of our database is not sorted, we enter false into this argument: That’s it!  We’ve entered all the information required for VLOOKUP to return the value we need.  Click the OK button and notice that the description corresponding to item code “R99245” has been correctly entered into cell B11: The formula that was created for us looks like this: If we enter a different item code into cell A11, we will begin to see the power of the VLOOKUP function:  The description cell changes to match the new item code: We can perform a similar set of steps to get the item’s price returned into cell E11.  Note that the new formula must be created in cell E11.  The result will look like this: …and the formula will look like this: Note that the only difference between the two formulae is the third argument (Col_index_num) has changed from a “2” to a “3” (because we want data retrieved from the 3rd column in the database). If we decided to buy 2 of these items, we would enter a “2” into cell D11.  We would then enter a simple formula into cell F11 to get the line total: =D11*E11 …which looks like this… Completing the Invoice Template We’ve learned a lot about VLOOKUP so far.  In fact, we’ve learned all we’re going to learn in this article.  It’s important to note that VLOOKUP can be used in other circumstances besides databases.  This is less common, and may be covered in future How-To Geek articles. Our invoice template is not yet complete.  In order to complete it, we would do the following: We would remove the sample item code from cell A11 and the “2” from cell D11.  This will cause our newly created VLOOKUP formulae to display error messages: We can remedy this by judicious use of Excel’s IF() and ISBLANK() functions.  We change our formula from this…       =VLOOKUP(A11,’Product Database’!A2:D7,2,FALSE) …to this…       =IF(ISBLANK(A11),”",VLOOKUP(A11,’Product Database’!A2:D7,2,FALSE)) We would copy the formulas in cells B11, E11 and F11 down to the remainder of the item rows of the invoice.  Note that if we do this, the resulting formulas will no longer correctly refer to the database table.  We could fix this by changing the cell references for the database to absolute cell references.  Alternatively – and even better – we could create a range name for the entire product database (such as “Products”), and use this range name instead of the cell references.  The formula would change from this…       =IF(ISBLANK(A11),”",VLOOKUP(A11,’Product Database’!A2:D7,2,FALSE)) …to this…       =IF(ISBLANK(A11),”",VLOOKUP(A11,Products,2,FALSE)) …and then copy the formulas down to the rest of the invoice item rows. We would probably “lock” the cells that contain our formulae (or rather unlock the other cells), and then protect the worksheet, in order to ensure that our carefully constructed formulae are not accidentally overwritten when someone comes to fill in the invoice. We would save the file as a template, so that it could be reused by everyone in our company If we were feeling really clever, we would create a database of all our customers in another worksheet, and then use the customer ID entered in cell F5 to automatically fill in the customer’s name and address in cells B6, B7 and B8.

• ASP.NET Web API - Screencast series with downloadable sample code - Part 1

  - by Jon Galloway

  There's a lot of great ASP.NET Web API content on the ASP.NET website at http://asp.net/web-api. I mentioned my screencast series in original announcement post, but we've since added the sample code so I thought it was worth pointing the series out specifically. 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. So - let's watch them together! Grab some popcorn and pay attention, because these are short. After each video, I'll talk about what I thought was important. I'm embedding the videos using HTML5 (MP4) with Silverlight fallback, but if something goes wrong or your browser / device / whatever doesn't support them, I'll include the link to where the videos are more professionally hosted on the ASP.NET site. Note also if you're following along with the samples that, since Part 1 just looks at the File / New Project step, the screencast part numbers are one ahead of the sample part numbers - so screencast 4 matches with sample code demo 3. Note: I started this as one long post for all 6 parts, but as it grew over 2000 words I figured it'd be better to break it up. Part 1: Your First Web API [Video and code on the ASP.NET site] This screencast starts with an overview of why you'd want to use ASP.NET Web API: Reach more clients (thinking beyond the browser to mobile clients, other applications, etc.) Scale (who doesn't love the cloud?!) Embrace HTTP (a focus on HTTP both on client and server really simplifies and focuses service interactions) Next, I start a new ASP.NET Web API application and show some of the basics of the ApiController. We don't write any new code in this first step, just look at the example controller that's created by File / New Project. using System; using System.Collections.Generic; using System.Linq; using System.Net.Http; using System.Web.Http; namespace NewProject_Mvc4BetaWebApi.Controllers { public class ValuesController : ApiController { // GET /api/values public IEnumerable<string> Get() { return new string[] { "value1", "value2" }; } // GET /api/values/5 public string Get(int id) { return "value"; } // POST /api/values public void Post(string value) { } // PUT /api/values/5 public void Put(int id, string value) { } // DELETE /api/values/5 public void Delete(int id) { } } } Finally, we walk through testing the output of this API controller using browser tools. There are several ways you can test API output, including Fiddler (as described by Scott Hanselman in this post) and built-in developer tools available in all modern browsers. For simplicity I used Internet Explorer 9 F12 developer tools, but you're of course welcome to use whatever you'd like. A few important things to note: This class derives from an ApiController base class, not the standard ASP.NET MVC Controller base class. They're similar in places where API's and HTML returning controller uses are similar, and different where API and HTML use differ. A good example of where those things are different is in the routing conventions. In an HTTP controller, there's no need for an "action" to be specified, since the HTTP verbs are the actions. We don't need to do anything to map verbs to actions; when a request comes in to /api/values/5 with the DELETE HTTP verb, it'll automatically be handled by the Delete method in an ApiController. The comments above the API methods show sample URL's and HTTP verbs, so we can test out the first two GET methods by browsing to the site in IE9, hitting F12 to bring up the tools, and entering /api/values in the URL: That sample action returns a list of values. To get just one value back, we'd browse to /values/5: That's it for Part 1. In Part 2 we'll look at getting data (beyond hardcoded strings) and start building out a sample application.

• My ASP.NET news sources

  - by Jon Galloway

  I just posted about the ASP.NET Daily Community Spotlight. I was going to list a bunch of my news sources at the end, but figured this deserves a separate post. I've been following a lot of development blogs for a long time - for a while I subscribed to over 1500 feeds and read them all. That doesn't scale very well, though, and it's really time consuming. Since the community spotlight requires an interesting ASP.NET post every day of the year, I've come up with a few sources of ASP.NET news. Top Link Blogs Chris Alcock's The Morning Brew is a must-read blog which highlights each day's best blog posts across the .NET community. He covers the entire Microsoft development, but generally any of the top ASP.NET posts I see either have already been listed on The Morning Brew or will be there soon. Elijah Manor posts a lot of great content, which is available in his Twitter feed at @elijahmanor, on his Delicious feed, and on a dedicated website - Web Dev Tweets. While not 100% ASP.NET focused, I've been appreciating Joe Stagner's Weekly Links series, partly since he includes a lot of links that don't show up on my other lists. Twitter Over the past few years, I've been getting more and more of my information from my Twitter network (as opposed to RSS or other means). Twitter is as good as your network, so if getting good information off Twitter sounds crazy, you're probably not following the right people. I already mentioned Elijah Manor (@elijahmanor). I follow over a thousand people on Twitter, so I'm not going to try to pick and choose a list, but one good way to get started building out a Twitter network is to follow active Twitter users on the ASP.NET team at Microsoft: @scottgu (well, not on the ASP.NET team, but their great grand boss, and always a great source of ASP.NET info) @shanselman @haacked @bradwilson @davidfowl @InfinitiesLoop @davidebbo @marcind @DamianEdwards @stevensanderson @bleroy @humancompiler @osbornm @anurse I'm sure I'm missing a few, and I'll update the list. Building a Twitter network that follows topics you're interested in allows you to use other tools like Cadmus to automatically summarize top content by leveraging the collective input of many users. Twitter Search with Topsy You can search Twitter for hashtags (like #aspnet, #aspnetmvc, and #webmatrix) to get a raw view of what people are talking about on Twitter. Twitter's search is pretty poor; I prefer Topsy. Here's an example search for the #aspnetmvc hashtag: http://topsy.com/s?q=%23aspnetmvc You can also do combined queries for several tags: http://topsy.com/s?q=%23aspnetmvc+OR+%23aspnet+OR+%23webmatrix Paper.li Paper.li is a handy service that builds a custom daily newspaper based on your social network. They've turned a lot of people off by automatically tweeting "The SuperDevFoo Daily is out!!!" messages (which can be turned off), but if you're ignoring them because of those message, you're missing out on a handy, free service. My paper.li page includes content across a lot of interests, including ASP.NET: http://paper.li/jongalloway When I want to drill into a specific tag, though, I'll just look at the Paper.li post for that hashtag. For example, here's the #aspnetmvc paper.li page: http://paper.li/tag/aspnetmvc Delicious I mentioned previously that I use Delicious for managing site links. I also use their network and search features. The tag based search is pretty good: Even better, though, is that I can see who's bookmarked these links, and add them to my Delicious network. After having built out a network, I can optimize by doing less searching and more leaching leveraging of collective intelligence. Community Sites I scan DotNetKicks, the weblogs.asp.net combined feed, and the ASP.NET Community page, CodeBetter, Los Techies,  CodeProject,  and DotNetSlackers from time to time. They're hit and miss, but they do offer more of an opportunity for finding original content which others may have missed. Terms of Enrampagement When someone's on a tear, I just manually check their sites more often. I could use RSS for that, but it changes pretty often. I just keep a mental note of people who are cranking out a lot of good content and check their sites more often. What works for you?

• OBIEE 11.1.1 - Introduction to OBIEE 11g Full Sample App

  - by user809526

  Isn't it nice to discover OBIEE 11g around a nice "How To" catalog of features? to observe OBI and Essbase relationships at work? to discover TimesTen? The OBIEE 11g Full Sample App (FSA) is a comprehensive collection of examples designed to demonstrate the latest Oracle BIEE 11g capabilities and design best practices: Enhanced visualizations as Geo-spacial maps and interactive dashboards, Action Framework,  BI Publisher, Scorecard and Strategy Management, Mobile style sheets, Semantic layer modeling, Multi-source federation, Integration with products such as Essbase, Oracle OLAP, ODM, TimesTen, ODI and more The FSA is intended to be comprehensive, it is big (see CAVEAT below). The FSA is not an Oracle product, it is a good will free deployment of OBIEE/Essbase designed to exemplify OBIEE features, infrastructure and security around the Fusion Middleware components. Its contents and code are distributed free for demonstrative purposes only. It is neither maintained nor supported by Oracle as a licensed product. The OBIEE Full Sample App is independent of the default Sample App that comes with the OBIEE product. BENEFITS The FSA helps as a demonstrator of OBIEE 11g best practices, a tutorial, an environment "Test & Scrap", a SR bench (regression, conflicts), a tuning bench, a quick ready made POC seed for projects, a security options environment, ... The FSA - Is organized around a catalog of functional features - Has been deployed over 1000 times, it should be stable RELEASE The Full Sample App (V107) is bound to OBIEE 11.1.1.5 and Essbase 11.1.2.1 (November 2011). The FSA release dates are independent of the Product GA date (OBIEE). In early December 2011, a new functional Patch (V110) is released. It is easily applied (in less than 15 mins) on top of OBIEE SampleApp 11.1.1.5 (V107). The patch (V110) includes additional functional examples:        1. Web Catalog Statistics Application: Provides detailed insight into your web catalog content, dormant catalog objects, webcat impact analysis for metadata changes and more        2. Data inflation Scripts: A set of simple SQL procedures to quickly inflate SampleApp Fact and Dimension data to millions of records in a few minutes        3. Public Content Extensions Framework: A patching framework for public examples and contributions leveraging SampleApp        4. Additional report examples (including bridge report, external chart integrations) and bug fixes DISTRIBUTION as VBox image (November 2011) The ready made VBox image is designed to run on Virtual Box. It can be converted to VMware (see another BLOG). 1/ http://www.oracle.com/technetwork/middleware/bi-foundation/obiee-samples-167534.html VBox Image Deployment Guide Sampleapp_v107_GA.ovf - VBox image key file The above http URL provides the user:password for the ftp URLs below. 2/ ftp://user:[email protected]/static/SampleAppV107/ 12 "7-zip" files Sampleapp_v107_GA_7_20.7z.001 -> .012 We recommend 7-zip file manager for unzipping (http://www.7-zip.org/).

It is strongly advised you run some memory check program eg MEMTEST in GRUB boot manager. Running md5sum repeatedly onto the very same big file must be consistent [same result], else a hardware memory problem is suspected. For Virtual Box, you should most likely enable VT-X (Vanderpool) hardware virtualization in BIOS. A free disk space of 80 GB is required to perform safely the VBox image installation. A Virtual Machine of minimum 6 to 7 GB memory fits the needs of combining OBIEE and Essbase execution.

• Logging WebSocket Frames using Chrome Developer Tools, Net-internals and Wireshark (TOTD #184)

  - by arungupta

  TOTD #183 explained how to build a WebSocket-driven application using GlassFish 4. This Tip Of The Day (TOTD) will explain how do view/debug on-the-wire messages, or frames as they are called in WebSocket parlance, over this upgraded connection. This blog will use the application built in TOTD #183. First of all, make sure you are using a browser that supports WebSocket. If you recall from TOTD #183 then WebSocket is combination of Protocol and JavaScript API. A browser supporting WebSocket, or not, means they understand your web pages with the WebSocket JavaScript. caniuse.com/websockets provide a current status of WebSocket support in different browsers. Most of the major browsers such as Chrome, Firefox, Safari already support WebSocket for the past few versions. As of this writing, IE still does not support WebSocket however its planned for a future release. Viewing WebSocket farmes require special settings because all the communication happens over an upgraded HTTP connection over a single TCP connection. If you are building your application using Java, then there are two common ways to debug WebSocket messages today. Other language libraries provide different mechanisms to log the messages. Lets get started! Chrome Developer Tools provide information about the initial handshake only. This can be viewed in the Network tab and selecting the endpoint hosting the WebSocket endpoint. You can also click on "WebSockets" on the bottom-right to show only the WebSocket endpoints. Click on "Frames" in the right panel to view the actual frames being exchanged between the client and server. The frames are not refreshed when new messages are sent or received. You need to refresh the panel by clicking on the endpoint again. To see more detailed information about the WebSocket frames, you need to type "chrome://net-internals" in a new tab. Click on "Sockets" in the left navigation bar and then on "View live sockets" to see the page. Select the box with the address to your WebSocket endpoint and see some basic information about connection and bytes exchanged between the client and the endpoint. Clicking on the blue text "source dependency ..." shows more details about the handshake. If you are interested in viewing the exact payload of WebSocket messages then you need a network sniffer. These tools are used to snoop network traffic and provide a lot more details about the raw messages exchanged over the network. However because they provide lot more information so they need to be configured in order to view the relevant information. Wireshark (nee Ethereal) is a pretty standard tool for sniffing network traffic and will be used here. For this blog purpose, we'll assume that the WebSocket endpoint is hosted on the local machine. These tools do allow to sniff traffic across the network though. Wireshark is quite a comprehensive tool and we'll capture traffic on the loopback address. Start wireshark, select "loopback" and click on "Start". By default, all traffic information on the loopback address is displayed. That includes tons of TCP protocol messages, applications running on your local machines (like GlassFish or Dropbox on mine), and many others. Specify "http" as the filter in the top-left. Invoke the application built in TOTD #183 and click on "Say Hello" button once. The output in wireshark looks like Here is a description of the messages exchanged: Message #4: Initial HTTP request of the JSP page Message #6: Response returning the JSP page Message #16: HTTP Upgrade request Message #18: Upgrade request accepted Message #20: Request favicon Message #22: Responding with favicon not found Message #24: Browser making a WebSocket request to the endpoint Message #26: WebSocket endpoint responding back You can also use Fiddler to debug your WebSocket messages. How are you viewing your WebSocket messages ? Here are some references for you: JSR 356: Java API for WebSocket - Specification (Early Draft) and Implementation (already integrated in GlassFish 4 promoted builds) TOTD #183 - Getting Started with WebSocket in GlassFish Subsequent blogs will discuss the following topics (not necessary in that order) ...

• Things to install on a new machine – revisited

  - by RoyOsherove

  as I prepare to get a new dev machine at work, I write the things I am going to install on it, before writing the first line of code on that machine: Control Freak Tools: Everything Search Engine – a free and amazingly fast search engine for files all over your machine. (just file names, not inside files). This is so fast I use it almost as a replacement for my start menu, but it’s also great for finding those files that get hidden and tucked away in dark places on my system. Ever had a situation where you needed to see exactly how many copies of X.dll were hiding on your machine and where? this tool is perfect for that. Google Chrome. It’s just fast. very fast. and Firefox has become the IE of alternative browsers in terms of speed and memory. Don’t even get me started on IE. TweetDeck – get a complete view of what’s up on twitter Total Commander – my still favorite file manager, over five years now. KatMouse – will scroll any window your hovering on, even if it’s not an active window, when you use scroll the wheel on it. PowerIso or Daemon Tools – for loading up ISO images of discs LogMeIn Ignition – quick access to your LogMeIn computers for online Backup: JungleDisk or BackBlaze KeePass – save important passwords MS Security Essentials – free anti virus that’s quoest and doesn’t make a mess of your system. for home: uTorrent – a torrent client that can read rss feeds (like the ones from ezrss.it ) Camtasia Studio and SnagIt – for recording and capturing the screen, and then adding cool effects on top. Foxit PDF Reader – much faster that adove reader. Toddler Keys (for home) – for when your baby wants to play with your keyboard. Live Writer – for writing blog posts for Lenovo ThinkPads – Lenovo System Update – if you have a “custom” system instead of the one that came built in, this will keep all your lenovo drivers up to date. FileZilla – for FTP stuff All the utils from sysinternals, (or try the live-links) especially: AutoRuns for deciding what’s really going to load at startup, procmon to see what’s really going on with processes in your system   Developer stuff: Reflector. Pure magic. Time saver. See source code of any compiled assembly. Resharper. Great for productivity and navigation across your source code FinalBuilder – a commercial build automation tool. Love it. much better than any xml based time hog out there. TeamCity – a great visual and friendly server to manage continuous integration. powerful features. Test Lint – a free addin for vs 2010 I helped create, that checks your unit tests for possible problems and hints you about it. TestDriven.NET – a great test runner for vs 2008 and 2010 with some powerful features. VisualSVN – a commercial tool if you use subversion. very reliable addin for vs 2008 and 2010 Beyond Compare – a powerful file and directory comparison tool. I love the fact that you can right click in windows exporer on any file and select “select left side to compare”, then right click on another file and select “compare with left side”. Great usability thought! PostSharp 2.0 – for addind system wide concepts into your code (tracing, exception management). Goes great hand in hand with.. SmartInspect – a powerful framework and viewer for tracing for your application. lots of hidden features. Crypto Obfuscator – a relatively new obfuscation tool for .NET that seems to do the job very well. Crypto Licensing – from the same company –finally a licensing solution that seems to really fit what I needed. And it works. Fiddler 2 – great for debugging and tracing http traffic to and from your app. Debugging Tools for Windows and DebugDiag  - great for debugging scenarios. still wanting more? I think this should keep you busy for a while.   Regulator and Regulazy – for testing and generating regular expressions Notepad 2 – for quick editing and viewing with syntax highlighting

• Keep a Window on top with a handy AutoHotkey script

  - by Matthew Guay

  Are you tired of shuffling back and forth between windows to get your work done?  Here’s a handy tool that lets you keep any window always on top when you need it. There are many ways to use multiple windows efficiently, but sometimes it seems you need to keep a smaller one in front of a larger window and they never quite fit right.  Whether you’re trying to use Calculator and a web form at the same time, or see what music is playing while you’re catching up on your news, there’s many scenarios where it can be useful to keep one window always on top.  There are many utilities to do this, but they are often needlessly complicated and bloated.  Here we look at a better solution from Amit, our friend at Digital Inspiration. Always on Top Thanks to AutoHotkey, you can easily always keep any window on top of all the others on your screen.  You can download this as a small exe and run it directly, or can create it with a simple script in AutoHotkey.  For simplicity, we simply downloaded the application and ran it directly. To do this, download Always on Top (link below), and unzip the file. Once you’ve launched it, simply select the window you want to keep on top and press Ctrl+Space.  This program will now stay in front, even when it is not the active window.  Here’s a screenshot of a Hotmail signup dialog in Chrome with Notepad kept on top.  Notice Notepad isn’t the active application, but it is still on top. If you wish to un-pin the window from being on top, simply select the window and press Ctrl+space again.  You can keep multiple windows pinned at once, too, though you may clutter your desktop quickly! Always on Top will keep running in your system tray, and you can exit or suspend it by right-clicking on its tray icon and selecting exit or suspend, respectively. Create Your Own Always on Top Utility with AutoHotkey If you’re a fan of AutoHotkey, you can create your own AutoHotkey script to keep windows on top simply and easily with only one line of code: ^SPACE:: Winset, Alwaysontop, , A Simply create a new file, insert the code, and save it as plaintext with the .ahk file extension.  If you have AutoHotkey installed, simply double-click this file for the exact same functionality as the premade version. Conclusion This is a great way to keep a window handy, and it can be beneficial in many scenarios.  For instance you can use it to copy data from a PDF or image into a form or spreadsheet, and it saves a lot of clicks and time.  Links: Download Always on Top from Digital Inspiration Download AutoHotkey if you want to make it yourself Similar Articles Productive Geek Tips Get the Linux Alt+Window Drag Functionality in WindowsGet Mac’s Hide Others (cmd+opt+H) Keyboard Shortcut for WindowsAdd "Run as Administrator" for AutoHotkey Scripts in Windows 7 or VistaKeyboard Ninja: Pop Up the Vista Calendar with a Single HotkeyKeyboard Ninja: Assign a Hotkey to any Window TouchFreeze Alternative in AutoHotkey The Icy Undertow Desktop Windows Home Server – Backup to LAN The Clear & Clean Desktop Use This Bookmarklet to Easily Get Albums Use AutoHotkey to Assign a Hotkey to a Specific Window Latest Software Reviews Tinyhacker Random Tips Revo Uninstaller Pro Registry Mechanic 9 for Windows PC Tools Internet Security Suite 2010 PCmover Professional OutSync will Sync Photos of your Friends on Facebook and Outlook Windows 7 Easter Theme YoWindoW, a real time weather screensaver Optimize your computer the Microsoft way Stormpulse provides slick, real time weather data Geek Parents – Did you try Parental Controls in Windows 7?

• C#/.NET Fundamentals: Choosing the Right Collection Class

  - by James Michael Hare

  The .NET Base Class Library (BCL) has a wide array of collection classes at your disposal which make it easy to manage collections of objects. While it's great to have so many classes available, it can be daunting to choose the right collection to use for any given situation. As hard as it may be, choosing the right collection can be absolutely key to the performance and maintainability of your application! This post will look at breaking down any confusion between each collection and the situations in which they excel. We will be spending most of our time looking at the System.Collections.Generic namespace, which is the recommended set of collections. The Generic Collections: System.Collections.Generic namespace The generic collections were introduced in .NET 2.0 in the System.Collections.Generic namespace. This is the main body of collections you should tend to focus on first, as they will tend to suit 99% of your needs right up front. It is important to note that the generic collections are unsynchronized. This decision was made for performance reasons because depending on how you are using the collections its completely possible that synchronization may not be required or may be needed on a higher level than simple method-level synchronization. Furthermore, concurrent read access (all writes done at beginning and never again) is always safe, but for concurrent mixed access you should either synchronize the collection or use one of the concurrent collections. So let's look at each of the collections in turn and its various pros and cons, at the end we'll summarize with a table to help make it easier to compare and contrast the different collections. The Associative Collection Classes Associative collections store a value in the collection by providing a key that is used to add/remove/lookup the item. Hence, the container associates the value with the key. These collections are most useful when you need to lookup/manipulate a collection using a key value. For example, if you wanted to look up an order in a collection of orders by an order id, you might have an associative collection where they key is the order id and the value is the order. The Dictionary<TKey,TVale> is probably the most used associative container class. The Dictionary<TKey,TValue> is the fastest class for associative lookups/inserts/deletes because it uses a hash table under the covers. Because the keys are hashed, the key type should correctly implement GetHashCode() and Equals() appropriately or you should provide an external IEqualityComparer to the dictionary on construction. The insert/delete/lookup time of items in the dictionary is amortized constant time - O(1) - which means no matter how big the dictionary gets, the time it takes to find something remains relatively constant. This is highly desirable for high-speed lookups. The only downside is that the dictionary, by nature of using a hash table, is unordered, so you cannot easily traverse the items in a Dictionary in order. The SortedDictionary<TKey,TValue> is similar to the Dictionary<TKey,TValue> in usage but very different in implementation. The SortedDictionary<TKey,TValye> uses a binary tree under the covers to maintain the items in order by the key. As a consequence of sorting, the type used for the key must correctly implement IComparable<TKey> so that the keys can be correctly sorted. The sorted dictionary trades a little bit of lookup time for the ability to maintain the items in order, thus insert/delete/lookup times in a sorted dictionary are logarithmic - O(log n). Generally speaking, with logarithmic time, you can double the size of the collection and it only has to perform one extra comparison to find the item. Use the SortedDictionary<TKey,TValue> when you want fast lookups but also want to be able to maintain the collection in order by the key. The SortedList<TKey,TValue> is the other ordered associative container class in the generic containers. Once again SortedList<TKey,TValue>, like SortedDictionary<TKey,TValue>, uses a key to sort key-value pairs. Unlike SortedDictionary, however, items in a SortedList are stored as an ordered array of items. This means that insertions and deletions are linear - O(n) - because deleting or adding an item may involve shifting all items up or down in the list. Lookup time, however is O(log n) because the SortedList can use a binary search to find any item in the list by its key. So why would you ever want to do this? Well, the answer is that if you are going to load the SortedList up-front, the insertions will be slower, but because array indexing is faster than following object links, lookups are marginally faster than a SortedDictionary. Once again I'd use this in situations where you want fast lookups and want to maintain the collection in order by the key, and where insertions and deletions are rare. The Non-Associative Containers The other container classes are non-associative. They don't use keys to manipulate the collection but rely on the object itself being stored or some other means (such as index) to manipulate the collection. The List<T> is a basic contiguous storage container. Some people may call this a vector or dynamic array. Essentially it is an array of items that grow once its current capacity is exceeded. Because the items are stored contiguously as an array, you can access items in the List<T> by index very quickly. However inserting and removing in the beginning or middle of the List<T> are very costly because you must shift all the items up or down as you delete or insert respectively. However, adding and removing at the end of a List<T> is an amortized constant operation - O(1). Typically List<T> is the standard go-to collection when you don't have any other constraints, and typically we favor a List<T> even over arrays unless we are sure the size will remain absolutely fixed. The LinkedList<T> is a basic implementation of a doubly-linked list. This means that you can add or remove items in the middle of a linked list very quickly (because there's no items to move up or down in contiguous memory), but you also lose the ability to index items by position quickly. Most of the time we tend to favor List<T> over LinkedList<T> unless you are doing a lot of adding and removing from the collection, in which case a LinkedList<T> may make more sense. The HashSet<T> is an unordered collection of unique items. This means that the collection cannot have duplicates and no order is maintained. Logically, this is very similar to having a Dictionary<TKey,TValue> where the TKey and TValue both refer to the same object. This collection is very useful for maintaining a collection of items you wish to check membership against. For example, if you receive an order for a given vendor code, you may want to check to make sure the vendor code belongs to the set of vendor codes you handle. In these cases a HashSet<T> is useful for super-quick lookups where order is not important. Once again, like in Dictionary, the type T should have a valid implementation of GetHashCode() and Equals(), or you should provide an appropriate IEqualityComparer<T> to the HashSet<T> on construction. The SortedSet<T> is to HashSet<T> what the SortedDictionary<TKey,TValue> is to Dictionary<TKey,TValue>. That is, the SortedSet<T> is a binary tree where the key and value are the same object. This once again means that adding/removing/lookups are logarithmic - O(log n) - but you gain the ability to iterate over the items in order. For this collection to be effective, type T must implement IComparable<T> or you need to supply an external IComparer<T>. Finally, the Stack<T> and Queue<T> are two very specific collections that allow you to handle a sequential collection of objects in very specific ways. The Stack<T> is a last-in-first-out (LIFO) container where items are added and removed from the top of the stack. Typically this is useful in situations where you want to stack actions and then be able to undo those actions in reverse order as needed. The Queue<T> on the other hand is a first-in-first-out container which adds items at the end of the queue and removes items from the front. This is useful for situations where you need to process items in the order in which they came, such as a print spooler or waiting lines. So that's the basic collections. Let's summarize what we've learned in a quick reference table.  Collection Ordered? Contiguous Storage? Direct Access? Lookup Efficiency Manipulate Efficiency Notes Dictionary No Yes Via Key Key: O(1) O(1) Best for high performance lookups. SortedDictionary Yes No Via Key Key: O(log n) O(log n) Compromise of Dictionary speed and ordering, uses binary search tree. SortedList Yes Yes Via Key Key: O(log n) O(n) Very similar to SortedDictionary, except tree is implemented in an array, so has faster lookup on preloaded data, but slower loads. List No Yes Via Index Index: O(1) Value: O(n) O(n) Best for smaller lists where direct access required and no ordering. LinkedList No No No Value: O(n) O(1) Best for lists where inserting/deleting in middle is common and no direct access required. HashSet No Yes Via Key Key: O(1) O(1) Unique unordered collection, like a Dictionary except key and value are same object. SortedSet Yes No Via Key Key: O(log n) O(log n) Unique ordered collection, like SortedDictionary except key and value are same object. Stack No Yes Only Top Top: O(1) O(1)* Essentially same as List<T> except only process as LIFO Queue No Yes Only Front Front: O(1) O(1) Essentially same as List<T> except only process as FIFO   The Original Collections: System.Collections namespace The original collection classes are largely considered deprecated by developers and by Microsoft itself. In fact they indicate that for the most part you should always favor the generic or concurrent collections, and only use the original collections when you are dealing with legacy .NET code. Because these collections are out of vogue, let's just briefly mention the original collection and their generic equivalents: ArrayList A dynamic, contiguous collection of objects. Favor the generic collection List<T> instead. Hashtable Associative, unordered collection of key-value pairs of objects. Favor the generic collection Dictionary<TKey,TValue> instead. Queue First-in-first-out (FIFO) collection of objects. Favor the generic collection Queue<T> instead. SortedList Associative, ordered collection of key-value pairs of objects. Favor the generic collection SortedList<T> instead. Stack Last-in-first-out (LIFO) collection of objects. Favor the generic collection Stack<T> instead. In general, the older collections are non-type-safe and in some cases less performant than their generic counterparts. Once again, the only reason you should fall back on these older collections is for backward compatibility with legacy code and libraries only. The Concurrent Collections: System.Collections.Concurrent namespace The concurrent collections are new as of .NET 4.0 and are included in the System.Collections.Concurrent namespace. These collections are optimized for use in situations where multi-threaded read and write access of a collection is desired. The concurrent queue, stack, and dictionary work much as you'd expect.

For more information see C#/.NET Little Wonders: The ConcurrentBag and BlockingCollection Summary The .NET BCL has lots of collections built in to help you store and manipulate collections of data. Understanding how these collections work and knowing in which situations each container is best is one of the key skills necessary to build more performant code. Choosing the wrong collection for the job can make your code much slower or even harder to maintain if you choose one that doesn’t perform as well or otherwise doesn’t exactly fit the situation. Remember to avoid the original collections and stick with the generic collections.  If you need concurrent access, you can use the generic collections if the data is read-only, or consider the concurrent collections for mixed-access if you are running on .NET 4.0 or higher.   Tweet Technorati Tags: C#,.NET,Collecitons,Generic,Concurrent,Dictionary,List,Stack,Queue,SortedList,SortedDictionary,HashSet,SortedSet

• Extracting the Date from a DateTime in Entity Framework 4 and LINQ

  - by Ken Cox [MVP]

  In my current ASP.NET 4 project, I’m displaying dates in a GridDateTimeColumn of Telerik’s ASP.NET Radgrid control. I don’t care about the time stuff, so my DataFormatString shows only the date bits: <telerik:GridDateTimeColumn FilterControlWidth="100px"   DataField="DateCreated" HeaderText="Created"    SortExpression="DateCreated" ReadOnly="True"    UniqueName="DateCreated" PickerType="DatePicker"    DataFormatString="{0:dd MMM yy}"> My problem was that I couldn’t get the built-in column filtering (it uses Telerik’s DatePicker control) to behave.  The DatePicker assumes that the time is 00:00:00 but the data would have times like 09:22:21. So, when you select a date and apply the EqualTo filter, you get no results. You would get results if all the time portions were 00:00:00. In essence, I wanted my Entity Framework query to give the DatePicker what it wanted… a Date without the Time portion. Fortunately, EF4 provides the TruncateTime  function. After you include Imports System.Data.Objects.EntityFunctions You’ll find that your EF queries will accept the TruncateTime function. Here’s my routine: Protected Sub RadGrid1_NeedDataSource _     (ByVal source As Object, _      ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) _     Handles RadGrid1.NeedDataSource     Dim ent As New OfficeBookDBEntities1     Dim TopBOMs = From t In ent.TopBom, i In ent.Items _                   Where t.BusActivityID = busActivityID _       And i.BusActivityID And t.ItemID = i.RecordID _       Order By t.DateUpdated Descending _       Select New With {.TopBomID = t.TopBomID, .ItemID = t.ItemID, _                        .PartNumber = i.PartNumber, _                        .Description = i.Description, .Notes = t.Notes, _                        .DateCreated = TruncateTime(t.DateCreated), _                        .DateUpdated = TruncateTime(t.DateUpdated)}     RadGrid1.DataSource = TopBOMs End Sub Now when I select March 14, 2011 on the DatePicker, the filter doesn’t stumble on time values that don’t make sense. Full Disclosure: Telerik gives me (and other developer MVPs) free copies of their suite.

• Windows Phone 7: Building a simple dictionary web client

  - by TechTwaddle

  Like I mentioned in this post a while back, I came across a dictionary web service called Aonaware that serves up word definitions from various dictionaries and is really easy to use. The services page on their website, http://services.aonaware.com/DictService/DictService.asmx, lists all the operations that are supported by the dictionary service. Here they are, Word Dictionary Web Service The following operations are supported. For a formal definition, please review the Service Description. Define Define given word, returning definitions from all dictionaries DefineInDict Define given word, returning definitions from specified dictionary DictionaryInfo Show information about the specified dictionary DictionaryList Returns a list of available dictionaries DictionaryListExtended Returns a list of advanced dictionaries (e.g. translating dictionaries) Match Look for matching words in all dictionaries using the given strategy MatchInDict Look for matching words in the specified dictionary using the given strategy ServerInfo Show remote server information StrategyList Return list of all available strategies on the server Follow the links above to get more information on each API. In this post we will be building a simple windows phone 7 client which uses this service to get word definitions for words entered by the user. The application will also allow the user to select a dictionary from all the available ones and look up the word definition in that dictionary. So of all the apis above we will be using only two, DictionaryList() to get a list of all supported dictionaries and DefineInDict() to get the word definition from a particular dictionary. Before we get started, a note to you all; I would have liked to implement this application using concepts from data binding, item templates, data templates etc. I have a basic understanding of what they are but, being a beginner, I am not very comfortable with those topics yet so I didn’t use them. I thought I’ll get this version out of the way and maybe in the next version I could give those a try. A somewhat scary mock-up of the what the final application will look like, Select Dictionary is a list picker control from the silverlight toolkit (you need to download and install the toolkit if you haven’t already). Below it is a textbox where the user can enter words to look up and a button beside it to fetch the word definition when clicked. Finally we have a textblock which occupies the remaining area and displays the word definition from the selected dictionary. Create a silverlight application for windows phone 7, AonawareDictionaryClient, and add references to the silverlight toolkit and the web service. From the solution explorer right on References and select Microsoft.Phone.Controls.Toolkit from under the .NET tab, Next, add a reference to the web service. Again right click on References and this time select Add Service Reference In the resulting dialog paste the service url in the Address field and press go, (url –> http://services.aonaware.com/DictService/DictService.asmx) once the service is discovered, provide a name for the NameSpace, in this case I’ve called it AonawareDictionaryService. Press OK. You can now use the classes and functions that are generated in the AonawareDictionaryClient.AonawareDictionaryService namespace. Let’s get the UI done now. In MainPage.xaml add a namespace declaration to use the toolkit controls, xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit" the content of LayoutRoot is changed as follows, (sorry, no syntax highlighting in this post) <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,5,0,5">     <TextBlock x:Name="ApplicationTitle" Text="AONAWARE DICTIONARY CLIENT" Style="{StaticResource PhoneTextNormalStyle}"/>     <!--<TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>--> </StackPanel> <!--ContentPanel - place additional content here--> <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">     <Grid.RowDefinitions>         <RowDefinition Height="Auto"/>         <RowDefinition Height="Auto"/>         <RowDefinition Height="*"/>     </Grid.RowDefinitions>     <toolkit:ListPicker Grid.Column="1" x:Name="listPickerDictionaryList"                         Header="Select Dictionary :">     </toolkit:ListPicker>     <Grid Grid.Row="1" Margin="0,5,0,0">         <Grid.ColumnDefinitions>             <ColumnDefinition Width="*"/>             <ColumnDefinition Width="Auto" />         </Grid.ColumnDefinitions>         <TextBox x:Name="txtboxInputWord" Grid.Column="0" GotFocus="OnTextboxInputWordGotFocus" />         <Button x:Name="btnGo" Grid.Column="1" Click="OnButtonGoClick" >             <Button.Content>                 <Image Source="/images/button-go.png"/>             </Button.Content>         </Button>     </Grid>     <ScrollViewer Grid.Row="2" x:Name="scrollViewer">         <TextBlock  Margin="12,5,12,5"  x:Name="txtBlockWordMeaning" HorizontalAlignment="Stretch"                    VerticalAlignment="Stretch" TextWrapping="Wrap"                    FontSize="26" />     </ScrollViewer> </Grid> I have commented out the PageTitle as it occupies too much valuable space, and the ContentPanel is changed to contain three rows. First row contains the list picker control, second row contains the textbox and the button, and the third row contains a textblock within a scroll viewer. The designer will now be showing the final ui, Now go to MainPage.xaml.cs, and add the following namespace declarations, using Microsoft.Phone.Controls; using AonawareDictionaryClient.AonawareDictionaryService; using System.IO.IsolatedStorage; A class called DictServiceSoapClient would have been created for you in the background when you added a reference to the web service. This class functions as a wrapper to the services exported by the web service. All the web service functions that we saw at the start can be access through this class, or more precisely through an object of this class. Create a data member of type DictServiceSoapClient in the Mainpage class, and a function which initializes it, DictServiceSoapClient DictSvcClient = null; private DictServiceSoapClient GetDictServiceSoapClient() {     if (null == DictSvcClient)     {         DictSvcClient = new DictServiceSoapClient();     }     return DictSvcClient; } We have two major tasks remaining. First, when the application loads we need to populate the list picker with all the supported dictionaries and second, when the user enters a word and clicks on the arrow button we need to fetch the word’s meaning. Populating the List Picker In the OnNavigatingTo event of the MainPage, we call the DictionaryList() api. This can also be done in the OnLoading event handler of the MainPage; not sure if one has an advantage over the other. Here’s the code for OnNavigatedTo, protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs e) {     DictServiceSoapClient client = GetDictServiceSoapClient();     client.DictionaryListCompleted += new EventHandler<DictionaryListCompletedEventArgs>(OnGetDictionaryListCompleted);     client.DictionaryListAsync();     base.OnNavigatedTo(e); } Windows Phone 7 supports only async calls to web services. When we added a reference to the dictionary service, asynchronous versions of all the functions were generated automatically. So in the above function we register a handler to the DictionaryListCompleted event which will occur when the call to DictionaryList() gets a response from the server. Then we call the DictionaryListAsynch() function which is the async version of the DictionaryList() api. The result of this api will be sent to the handler OnGetDictionaryListCompleted(), void OnGetDictionaryListCompleted(object sender, DictionaryListCompletedEventArgs e) {     IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;     Dictionary[] listOfDictionaries;     if (e.Error == null)     {         listOfDictionaries = e.Result;         PopulateListPicker(listOfDictionaries, settings);     }     else if (settings.Contains("SavedDictionaryList"))     {         listOfDictionaries = settings["SavedDictionaryList"] as Dictionary[];         PopulateListPicker(listOfDictionaries, settings);     }     else     {         MessageBoxResult res = MessageBox.Show("An error occured while retrieving dictionary list, do you want to try again?", "Error", MessageBoxButton.OKCancel);         if (MessageBoxResult.OK == res)         {             GetDictServiceSoapClient().DictionaryListAsync();         }     }     settings.Save(); } I have used IsolatedStorageSettings to store a few things; the entire dictionary list and the dictionary that is selected when the user exits the application, so that the next time when the user starts the application the current dictionary is set to the last selected value. First we check if the api returned any error, if the error object is null e.Result will contain the list (actually array) of Dictionary type objects. If there was an error, we check the isolated storage settings to see if there is a dictionary list stored from a previous instance of the application and if so, we populate the list picker based on this saved list. Note that in this case there are chances that the dictionary list might be out of date if there have been changes on the server. Finally, if none of these cases are true, we display an error message to the user and try to fetch the list again. PopulateListPicker() is passed the array of Dictionary objects and the settings object as well, void PopulateListPicker(Dictionary[] listOfDictionaries, IsolatedStorageSettings settings) {     listPickerDictionaryList.Items.Clear();     foreach (Dictionary dictionary in listOfDictionaries)     {         listPickerDictionaryList.Items.Add(dictionary.Name);     }     settings["SavedDictionaryList"] = listOfDictionaries;     string savedDictionaryName;     if (settings.Contains("SavedDictionary"))     {         savedDictionaryName = settings["SavedDictionary"] as string;     }     else     {         savedDictionaryName = "WordNet (r) 2.0"; //default dictionary, wordnet     }     foreach (string dictName in listPickerDictionaryList.Items)     {         if (dictName == savedDictionaryName)         {             listPickerDictionaryList.SelectedItem = dictName;             break;         }     }     settings["SavedDictionary"] = listPickerDictionaryList.SelectedItem as string; } We first clear all the items from the list picker, add the dictionary names from the array and then create a key in the settings called SavedDictionaryList and store the dictionary list in it. We then check if there is saved dictionary available from a previous instance, if there is, we set it as the selected item in the list picker. And if not, we set “WordNet ® 2.0” as the default dictionary. Before returning, we save the selected dictionary in the “SavedDictionary” key of the isolated storage settings. Fetching word definitions Getting this part done is very similar to the above code. We get the input word from the textbox, call into DefineInDictAsync() to fetch the definition and when DefineInDictAsync completes, we get the result and display it in the textblock. Here is the handler for the button click, private void OnButtonGoClick(object sender, RoutedEventArgs e) {     txtBlockWordMeaning.Text = "Please wait..";     IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;     if (txtboxInputWord.Text.Trim().Length <= 0)     {         MessageBox.Show("Please enter a word in the textbox and press 'Go'");     }     else     {         Dictionary[] listOfDictionaries = settings["SavedDictionaryList"] as Dictionary[];         string selectedDictionary = listPickerDictionaryList.SelectedItem.ToString();         string dictId = "wn"; //default dictionary is wordnet (wn is the dict id)         foreach (Dictionary dict in listOfDictionaries)         {             if (dict.Name == selectedDictionary)             {                 dictId = dict.Id;                 break;             }         }         DictServiceSoapClient client = GetDictServiceSoapClient();         client.DefineInDictCompleted += new EventHandler<DefineInDictCompletedEventArgs>(OnDefineInDictCompleted);         client.DefineInDictAsync(dictId, txtboxInputWord.Text.Trim());     } } We validate the input and then select the dictionary id based on the currently selected dictionary. We need the dictionary id because the api DefineInDict() expects the dictionary identifier and not the dictionary name. We could very well have stored the dictionary id in isolated storage settings too. Again, same as before, we register a event handler for the DefineInDictCompleted event and call the DefineInDictAsync() method passing in the dictionary id and the input word. void OnDefineInDictCompleted(object sender, DefineInDictCompletedEventArgs e) {     WordDefinition wd = e.Result;     scrollViewer.ScrollToVerticalOffset(0.0f);     if (wd.Definitions.Length == 0)     {         txtBlockWordMeaning.Text = String.Format("No definitions were found for '{0}' in '{1}'", txtboxInputWord.Text.Trim(), listPickerDictionaryList.SelectedItem.ToString().Trim());     }     else     {         foreach (Definition def in wd.Definitions)         {             string str = def.WordDefinition;             str = str.Replace("  ", " "); //some formatting             txtBlockWordMeaning.Text = str;         }     } } When the api completes, e.Result will contain a WordDefnition object. This class is also generated in the background while adding the service reference. We check the word definitions within this class to see if any results were returned, if not, we display a message to the user in the textblock. If a definition was found the text on the textblock is set to display the definition of the word. Adding final touches, we now need to save the current dictionary when the application exits. A small but useful thing is selecting the entire word in the input textbox when the user selects it. This makes sure that if the user has looked up a definition for a really long word, he doesn’t have to press ‘clear’ too many times to enter the next word, protected override void OnNavigatingFrom(System.Windows.Navigation.NavigatingCancelEventArgs e) {     IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;     settings["SavedDictionary"] = listPickerDictionaryList.SelectedItem as string;     settings.Save();     base.OnNavigatingFrom(e); } private void OnTextboxInputWordGotFocus(object sender, RoutedEventArgs e) {     TextBox txtbox = sender as TextBox;     if (txtbox.Text.Trim().Length > 0)     {         txtbox.SelectionStart = 0;         txtbox.SelectionLength = txtbox.Text.Length;     } } OnNavigatingFrom() is called whenever you navigate away from the MainPage, since our application contains only one page that would mean that it is exiting. I leave you with a short video of the application in action, but before that if you have any suggestions on how to make the code better and improve it please do leave a comment. Until next time…

• IPS Facets and Info files

  - by mkupfer

  One of the unusual things about IPS is its "facet" feature. For example, if you're a developer using the foo library, you don't install a libfoo-dev package to get the header files. Intead, you install the libfoo package, and your facet.devel setting controls whether you get header files. I was reminded of this recently when I tried to look at some documentation for Emacs Org mode. I was surprised when Emacs's Info browser said it couldn't find the top-level Info directory. I poked around in /usr/share but couldn't find any info files. $ ls -l /usr/share/info ls: cannot access /usr/share/info: No such file or directory Was I was missing a package? $ pkg list -a | egrep "info|emacs" editor/gnu-emacs 23.1-0.175.0.0.0.2.537 i-- editor/gnu-emacs/gnu-emacs-gtk 23.1-0.175.0.0.0.2.537 i-- editor/gnu-emacs/gnu-emacs-lisp 23.1-0.175.0.0.0.2.537 --- editor/gnu-emacs/gnu-emacs-no-x11 23.1-0.175.0.0.0.2.537 --- editor/gnu-emacs/gnu-emacs-x11 23.1-0.175.0.0.0.2.537 i-- system/data/terminfo 0.5.11-0.175.0.0.0.2.1 i-- system/data/terminfo/terminfo-core 0.5.11-0.175.0.0.0.2.1 i-- text/texinfo 4.7-0.175.0.0.0.2.537 i-- x11/diagnostic/x11-info-clients 7.6-0.175.0.0.0.0.1215 i-- $ Hmm. I didn't have the gnu-emacs-lisp package. That seemed an unlikely place to stick the Info files, and pkg(1) confirmed that the info files were not there: $ pkg contents -r gnu-emacs-lisp | grep info usr/share/emacs/23.1/lisp/info-look.el.gz usr/share/emacs/23.1/lisp/info-xref.el.gz usr/share/emacs/23.1/lisp/info.el.gz usr/share/emacs/23.1/lisp/informat.el.gz usr/share/emacs/23.1/lisp/org/org-info.el.gz usr/share/emacs/23.1/lisp/org/org-jsinfo.el.gz usr/share/emacs/23.1/lisp/pcvs-info.el.gz usr/share/emacs/23.1/lisp/textmodes/makeinfo.el.gz usr/share/emacs/23.1/lisp/textmodes/texinfo.el.gz $ Well, if I have what look like the right packages but don't have the right files, the next thing to check are the facets. The first check is whether there is a facet associated with the Info files: $ pkg contents -m gnu-emacs | grep usr/share/info dir facet.doc.info=true group=bin mode=0755 owner=root path=usr/share/info file [...] chash=[...] facet.doc.info=true group=bin mode=0444 owner=root path=usr/share/info/mh-e-1 [...] file [...] chash=[...] facet.doc.info=true group=bin mode=0444 owner=root path=usr/share/info/mh-e-2 [...] [...] Yes, they're associated with facet.doc.info. Now let's look at the facet settings on my desktop: $ pkg facet FACETS VALUE facet.locale.en* True facet.locale* False facet.doc.man True facet.doc* False $ Oops. I've got man pages and various English documentation files, but not the Info files. Let's fix that: # pkg change-facet facet.doc.info=True Packages to update: 970 Variants/Facets to change: 1 Create boot environment: No Create backup boot environment: Yes Services to change: 1 DOWNLOAD PKGS FILES XFER (MB) Completed 970/970 181/181 9.2/9.2 PHASE ACTIONS Install Phase 226/226 PHASE ITEMS Image State Update Phase 2/2 PHASE ITEMS Reading Existing Index 8/8 Indexing Packages 970/970 # Now we have the info files: $ ls -F /usr/share/info a2ps.info dir@ flex.info groff-2 regex.info aalib.info dired-x flex.info-1 groff-3 remember ...

• Do NOT Change "Copy Local” project references to false, unless understand subsequences.

  - by Michael Freidgeim

  To optimize performance of visual studio build I've found multiple recommendations to change CopyLocal property for dependent dlls to false,e.g. From http://stackoverflow.com/questions/690033/best-practices-for-large-solutions-in-visual-studio-2008 CopyLocal? For sure turn this offhttp://stackoverflow.com/questions/280751/what-is-the-best-practice-for-copy-local-and-with-project-referencesAlways set the Copy Local property to false and enforce this via a custom msbuild stephttp://codebetter.com/patricksmacchia/2007/06/20/benefit-from-the-c-and-vb-net-compilers-perf/BenefitBenefitMy advice is to always set ‘Copy Local’ to falseSome time ago we've tried to change the setting to false, and found that it causes problem for deployment of top-level projects.Recently I've followed the suggestion and changed the settings for middle-level projects. It didn't cause immediate issues, but I was warned by Readify Consultant Colin Savage about possible errors during deploymentsI haven't undone the changes immediately and we found a few issues during testing.There are many scenarios, when you need to have Copy Local’ left to True.The concerns are highlighted in some stack overflow answers, but they have small number of votes.Top-level projects:  set copy local = true.First of all, it doesn't work correctly for top-level projects, i.e. executables or web sites.As pointed in the answer http://stackoverflow.com/a/6529461/52277for all the references in the one at the top set copy local = true.Alternatively you have to change output directory as it's described in http://www.simple-talk.com/dotnet/.net-framework/partitioning-your-code-base-through-.net-assemblies-and-visual-studio-projects/If you set ‘ Copy Local = false’, VS will, unless you tell it otherwise, place each assembly alone in its own .\bin\Debugdirectory. Because of this, you will need to configure VS to place assemblies together in the same directory. To do so, for each VS project, go to VS > Project Properties > Build tab > Output path, and set the Ouput path to ..\bin\Debugfor debug configuration, and ..\bin\Release for release configuration.Second-level  dependencies:  set copy local = true.Another example when copylocal =false fails on run-time, is when top level assembly doesn't directly referenced one of indirect dependencies.E..g. Top-level assembly A has reference to assembly B with copylocal =true, but assembly B has reference to assembly C with copylocal =false. Most likely assembly C will be missing on runtime and will cause errors E.g. http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1Copy local is important for deployment scenarios and tools. As a general rule you should use CopyLocal=True and http://stackoverflow.com/questions/602765/when-should-copy-local-be-set-to-true-and-when-should-it-not?lq=1 Unfortunately there are some quirks and CopyLocal won't necessary work as expected for assembly references in secondary assemblies structured as shown below.MainApp.exe MyLibrary.dll ThirdPartyLibrary.dll (if in the GAC CopyLocal won't copy to MainApp bin folder)This makes xcopy deployments difficult . .Reflection called DLLs  dependencies:  set copy local = true.E.g user can see error "ISystem.Reflection.ReflectionTypeLoadException: Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information."The fix for the issue is recommended in http://stackoverflow.com/a/6200173/52277"I solved this issue by setting the Copy Local attribute of my project's references to true."In general, the problems with investigation of deployment issues may overweight the benefits of reduced build time. Setting the Copy Local to false without considering deployment issues is not a good idea.

• Book Reviews: Art of Community and Eyetracking Web Usability

  - by ultan o'broin

  Holidays time offers a chance to catch up on some user experience and user assistance related material. So, two short book reviews (which I considered using my new Tumblr blog for. More about that another time) coming up. The Art of Community by Jono Bacon Excellent starting point for anyone wanting to get going in the community software (FLOSS, for example) space or understand how to set up, manage, and leverage the collective intelligence of communities for whatever ends. The book is a little too long in my opinion, and of course, usage of what Jono is recommending needs to be nuanced and adapted for enterprise applications space (hardly surprising there is a lot about Ubuntu, Lug Radio, and so on given Jono's interests). Shame there wasn't more information on international, non-English community considerations too. Still, some great ideas and insight into setting up and managing communities that I will leverage (watch out for the results on this blog, later in 2011). One section, on collaborative writing really jumped out. It reinforced the whole idea that to successful community initiatives are based on instigators knowing what makes the community tick in the first place. How about this for insight into user profiles for people who write community user assistance (OK then, "doc") and what tools they might use (in this case, we're talking about Jokosher): "Most people who write documentation for open source software projects would fall into the category of power user. They are technology enthusiasts who are not interested in the super-technical avenues of programming, but want to help out. Many of these people have good writing skills and a good knowledge of using the software, so the documentation fit is natural. With Jokosher we wanted to acknowledge this profile of user. As such, instead of focussing on complex text processing tools, we encouraged our documentation contributors to use a wiki." The book is available for free here, and well as being available from usual sources. Eyetracking Web Usability by Jakob Nielsen and Kara Prentice Another fine book by established experts. I have some field experience of eyetracking studies myself --in the user assistance for enterprise applications space--though Jakob and Kara concentrate on websites for their research here. I would caution how much about websites transfers easily to the applications space, especially enterprise applications, as claimed in the book too. However, Jakob and Kara do make the case very well that understanding design goals (for example, productivity improvement in the case of applications) and the context of the software use is critical. Executing a study using eyetracking technology requires that you know what you want to test, can set up realistic tasks for testing by representative testers, and then analyze the results. Be precise, as lots of data will be generated (I think the authors underplay the effort in analyzing data too). What I found disappointing was the lack of emphasis on eyetracking as only part of the usability solution. It's really for fine-tuning designs in my opinion, and should be used after other design reviews. I also wasn't that crazy about the level of disengagement between the qualitative and quantitative side of this kind of testing that the book indicated. I think it is useful to have testers verbalize their thoughts and for test engineers to prompt, intervene, or guide as necessary. More on cultural or international aspects to usability testing might have been included too (websites are available to everyone). To conclude, I enjoyed the book, took on board some key takeaways about methodologies and found the recommendations sensible and easy to follow (for example about Forms layouts). Applying enterprise applications requirements such as those relating to user profiles, design goals, and overall context of use in conjunction with what's in this book would be the way to go here. It also made me think of how interesting it would be to compare eyetracking findings between website and enterprise applications usage.

• Drupal Modules for SEO & Content

  - by Aditi

  When we talk about Drupal SEO, there are two things to consider one is about the relevant SEO practices and about appropriate Drupal Modules available. Optimizing your website for search engines is one of the most important aspect of launching & promoting your website especially if ranking matters to you. Understanding SEO For starters, you have begin with Keyword research and then optimize your content according to your findings by tagging, meta tags etc, Drupal modules once installed help you manage a lot of such parameters. Identifying the target keywords Using the Page Title and Token modules PathAuto configuration <H1> heading tags Optimizing Drupal’s default robots.txt file Etc. While Drupal gives you a lot of ability to make your website content worthy & search engine friendly it is important for you to make sure you are not crossing the line or you could get penalized. Modules Overview Drupal Power is at its best when you have these modules & great brain working together. The basic SEO improvements can be achieved easily with the modules enlisted below, but you can win magical rankings if you use them logically & wisely. Understanding your keyword competition & enhancing your content is the basic key to success and ofcourse the modules: Pathauto Automatically create search enging friendly readable URLS from tokens. A token is a piece of data from content, say the author’s username, or the content’s title. For example mysite.com/an-article, rather than mysite.com/node/114 for every node you make. NodeWords Amazingly useful drupal module that allows you to create custom meta tags and descriptions for your nodes, which gives you the ability to target specific keywords and phrases. Page Title Enables you to set an alternative title for the <title></title> tags and for the <h1></h1> tags on a node. Global Redirect Manage content duplication, 301 redirects, and URL validation with this small, but powerful module. Taxonomy manager Make large additions, or changes to taxonomy very easy. This module provides a powerful interface for managing taxonomies. A vocabulary gets displayed in a dynamic tree view, where parent terms can be expanded to list their nested child terms or can be collapsed. robotstxt A robots.txt file is vital for ensuring that search engine spiders don’t index the unwanted areas of your site. This Drupal module gives you the ability to manage your robots.txt file through the CMS admin. xmlsitemap An XML Sitemap lets the search engines index your website content. This module helps in generating and maintaining a complete sitemap for your website and gives you control over exactly which parts of the site you want to be included in the index. It even gives you the ability to automatically submit your sitemap to Google, Yahoo!, Ask.com and Windows Live every time you update a node or at specific interval. Node Import This module allows you to import a set of nodes from a Comma Seperated Values (CSV) or Tab Seperated Values (TSV) text file. Makes it easy to import hundreds-thousands of csv rows and you get to tie up these rows to CCK fields (or locations), and it can file it under the right taxonomy hierarchy. This is Super life saver module.

• Time to stop using &ldquo;Execute Package Task&rdquo;&ndash; a way to execute package in SSIS catalog taking advantage of the new project deployment model ,and the logging and reporting feature

  - by Kevin Shyr

  I set out to find a way to dynamically call package in SSIS 2012.  The following are 2 excellent blogs I found; I used them heavily.  The code below has some addition to parameter types and message types, but was made essentially derived entirely from the blogs. http://sqlblog.com/blogs/jamie_thomson/archive/2011/07/16/ssis-logging-in-denali.aspx http://www.ssistalk.com/2012/07/24/quick-tip-run-ssis-2012-packages-synchronously-and-other-execution-options/   The code: Every package will be called by a PackageController package.  The packageController is initialized with some information on which package to run and what information to pass in.   The following is the stored procedure called from the “Execute SQL Task”.  Here is the highlight of the stored procedure It takes in packageName, project name, and folder name (folder in SSIS project deployment to SSIS catalog) The stored procedure sets the package variables of the upcoming package execution Execute package in SSIS Catalog Get the status of the execution.  Also, if exists, get the error message’s message_id and store them in the management database. Return value to “Execute SQL Task” to manage failure properly CREATE PROCEDURE [AUDIT].[LaunchPackageExecutionInSSISCatalog]        @PackageName NVARCHAR(255)        , @ProjectFolder NVARCHAR(255)        , @ProjectName NVARCHAR(255)        , @AuditKey INT        , @DisableNotification BIT        , @PackageExecutionLogID INT AS BEGIN TRY        DECLARE @execution_id BIGINT = 0;

• Multiplayer / Networking options for a 2D game with physics

  - by lahmas

  Summary: My 50% finished 2D sidescroller with Box2D as physics engine should have multiplayer support in the final version. However, the current code is just a singleplayer game. What should I do now? And more important, how should I implement multiplayer and combine it with singleplayer? Is it a bad idea to code the singleplayer mode separated from multiplayer mode (like Notch did it with Minecraft)? The performance in singleplayer should be as good as possible (Simulating physics with using a loopback server to implement singleplayer mode would be a problem there) Full background / questions: I'm working on a relatively large 2D game project in C++, with physics as a core element of it. (I use Box2D for that) The finished game should have full multiplayer support, however I made the mistake that I didn't plan the networking part properly and basically worked on a singleplayer game until now. I thought that multiplayer support could be added to the almost finished singleplayer game in a relatively easy and clear way, but apparently, from what I have read this is wrong. I even read that a multiplayer game should be programmed as one from the beginning, with the singleplayer mode actually just consisting of hosting an invisible local server and connecting to it via loopback. (I found out that most FPS game engines do it that way, an example would be Source) So here I am, with my half finished 2D sidescroller game, and I don't really know how to go on. Simply continueing to work on the singleplayer / client seems useless to me now, as I'd have to recode and refactor even more later. First, a general question to anybody who possibly found himself in a situation like this: How should I proceed? Then, the more specific one - I have been trying to find out how I can approach the networking part for my game: (Possible solutions:) Invisible / loopback server for singleplayer This would have the advantage that there basically is no difference between singleplayer and multiplayer mode. Not much additional code would be needed. A big disadvantage: Performance and other limitations in singleplayer. There would be two physics simulations running. One for the client and one for the loopback server. Even if you work around by providing a direct path for the data from the loopback server, through direct communcation by the threads for example, the singleplayer would be limited. This is a problem because people should be allowed to play around with masses of objects at once. Separated singleplayer / Multiplayer mode There would be no server involved in singleplayer mode. I'm not really sure how this would work. But at least I think that there would be a lot of additional work, because all of the singleplayer features would have to be re-implemented or glued to multiplayer mode. Multiplayer mode as a module for singleplayer This is merely a quick thought I had. Multiplayer could consist of a singleplayer game, with an additional networking module loaded and connected to a server, which sends and receives data and updates the singleplayer world. In the retrospective, I regret not having planned the multiplayer mode earlier. I'm really stuck at this point and I hope that somebody here is able to help me!
