• Sharing code in LGPL and proprietary software

  - by Martin

  Hi I'm working on a piece of software that'll be released as a dll under LGPL. The software interfaces with hardware from a small company that has provided me with the needed libraries and some code to use them correctly (not only headers but its all in a separate file). As far as i know, the same code is used in their proprietary software that they don't intend to open source but they'd be fine releasing the piece of code they've given me. Now here's the question: What license could be used on the code I got from the company? I guess using GPL or LGPL would make them violate GPL when using the same code in their other software. Is MIT a good idea? Is it ok to just include a file with MIT license on it in my otherwise LGPL:ed project? Since I'm not the copyright holder, I'd have to ask the company to apply the license obviously but that shouldn't be a problem. Thanks /Martin

• Unable to run Tor even in terminal, Vidalia exit code 127

  - by Ubuntu Newb

  I'm using Ubuntu 12.10 (quantal) and I recently installed Tor (32 bits) following the instructions on the Tor project's page. Then I started the script after having it extracted from the console and got this: master@ubuntu:~/tor-browser_en-US$ ./start-tor-browser Launching Tor Browser Bundle for Linux in /home/master/tor-browser_en-US ./start-tor-browser: 225: ./start-tor-browser: ./App/vidalia: not found Vidalia exited abnormally. Exit code: 127 Then I ran Vidalia from the console and: master@ubuntu:~/tor-browser_en-US$ vidalia (<unknown>:11354): IBUS-WARNING **: Unable to load /var/lib/dbus/machine-id: Failed to open file '/var/lib/dbus/machine-id': Permission denied master@ubuntu:~/tor-browser_en-US$ vidalia (<unknown>:11358): IBUS-WARNING **: Unable to load /var/lib/dbus/machine-id: Failed to open file '/var/lib/dbus/machine-id': Permission denied And after Vidalia's GUI opens I get the error prompt about starting Tor: "Vidalia was unable to start Tor. Check your settings to ensure the correct name and location of your Tor executable is specified." How can I start Tor?

• Powershell STA watin

  - by Mike Koerner

  Wow, two posts on the same day. I was working on a quick DLL project to do some web scripting using the awsome power of Watin.  In the past I use to create a vbscript as the test handler to call the DLL but lately I got a Powershell bug to call .NET DLLs. When I tried to debug the Watin call I received: The CurrentThread needs to have it's ApartmentState set to ApartmentState.STA to be able to automate Internet Explorer. I couldn't find a quick google answer to powershell apartmentstate .  Apparently you can set the powershell apartment state by the command line -STA.  http://technet.microsoft.com/en-us/library/dd315276.aspx I've found that the powershell documentation and examples is lacking compared to the Microsoft support I've come to expect.  Why is the Powershell v2.0 in C:\WINDOWS\SYSTEM32\windowspowershell\v1.0 ?

• Why should I consider using the Source Engine?

  - by dukeofgaming

  I've always been a Valve fan, but now that I have the opportuninty to choose a game engine for a project I'm not sure I want to choose the Source Engine after watching this wikipedia entry. My options essentially boiled down to an open source stack (Horde3D + Zoidcom + Spark + SFML + CEGUI, and well, not OSS but PhysX too), UDK and the Source Engine. My question is (because I really have no experience with it) what would be the technical reasons (not license or other) for any developer to choose the Source Engine over any other open source or commercial option ?, is the Source Engine really worth it as a game development tool or has it time already passed and it is obsolete against other solutions?. Thanks Edit: Precised my question a little more , I'm looking for technical reasons to choose the Source Engine.

• ASP.NET/IIS Fix: The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.

  - by Ken Cox [MVP]

  In my latest ASP.NET project, I refresh the sample data using an Excel spreadsheet from the client. After upgrading to Windows Server 2008 R2, I suddenly discovered this error: The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine. The error message is totally bogus! The problem is that I’m running IIS on a 64-bit machine and the ol’ OLEDB thingy just isn’t up with the times. To fix it, go into the IIS Manager and find out which Application Pool the site is using. In my case...(read more)

• Chart Control in ASP.Net 4 – Second Part

  - by sreejukg

    Couple of weeks before, I have written an introduction about the chart control available in .Net framework. In that article, I explained the basic usage of the chart control with a simple example. You can read that article from the url http://weblogs.asp.net/sreejukg/archive/2010/12/31/getting-started-with-chart-control-in-asp-net-4-0.aspx. In this article I am going to demonstrate how one can generate various types of charts that can be generated easily using the ASP.Net chart control. Let us recollect the data sample we were working in the previous sample. The following is the data I used in the previous article. id SaleAmount SalesPerson SaleType SaleDate CompletionStatus (%) 1 1000 Jack Development 2010-01-01 100 2 300 Mills Consultancy 2010-04-14 90 3 4000 Mills Development 2010-05-15 80 4 2500 Mike eMarketting 2010-06-15 40 5 1080 Jack Development 2010-07-15 30 6 6500 Mills Consultancy 2010-08-24 65 In this article I am going to demonstrate various graphical reports generated from this data with the help of chart control. The following are the reports I am going to generate 1. Representation of share of Sales by each Sales person. 2. Representation of share of sales data according to sale type 3. Representation of sales progress over time period I am going to demonstrate how to bind the chart control programmatically. In order to facilitate this, I created an aspx page named “SalesAnalysis.Aspx” to my project. In the page I added the following controls 1. Dropdownlist control – with id ddlAnalysisType, user will use this to choose the type of chart they want to see. 2. A Button control – with id btnSubmit , by clicking this button, the chart based on the dropdownlist selection will be shown to the user 3. A label Control – with id lblMessage, to display the message to the user, initially this will ask the user to select an option and click on the button. 4. Chart control – with id chrtAnalysis, by default, I set visible = false so that during the page load the chart will be hidden to the users. The following is the initial output of the page. Generating chart for salesperson share Now from Visual Studio, I have double clicked on the button; it created the event handler btnSubmit_Click. In the button Submit event handler, I am using a switch case to execute the corresponding SQL statement and bind it to the chart control. The below is the code for generating the sales person share chart using a pie chart. The above code produces the following output The steps for creating the above chart can be summarized as follows. You specify a chart area, then a series and bind the chart to some x and y values. That is it. If you want to control the chart size and position, you can set the properties for the ChartArea.Position element. For e.g. in the previous code, after instantiating the chart area, setting the below code will give you a bigger pie chart. c.Position.Width = 100; c.Position.Height = 100; The width and height values are in percentage. In this case the chart will be generated by utilizing all the width and height of the chart object. See the output updated with the width and height set to 100% each. Generate Chart for sales type share Now for generating the chart according to the sales type, you just need to change the SQL query and x and y values of the chart. The Sql query used is “SELECT SUM(saleAmount) amount, SaleType from SalesData group by SaleType” and the X-Value is amount and Y-Values is SaleType. s.XValueMember = "SaleType"; s.YValueMembers = "amount"; After modifying the above code with these, the following output is generated. Generate Chart for sales progress over time period For generating the progress of sale chart against sales amount / period, line chart is the ideal tool. In order to facilitate the line chart, you can use Chart Type as System.Web.UI.DataVisualization.Charting.SeriesChartType.Line. Also we need to retrieve the amount and sales date from the data source. I have used the following query to facilitate this. “SELECT SaleAmount, SaleDate FROM SalesData” The output for the line chart is as follows Now you have seen how easily you can build various types of charts. Chart control is an excellent one that helps you to bring business intelligence to your applications. What I demonstrated in only a small part of what you can do with the chart control. Refer http://msdn.microsoft.com/en-us/library/dd456632.aspx for further reading. If you want to get the project files in zip format, post your email below. Hope you enjoyed reading this article.

• Improve the Quality of ePub eBooks with Sigil

  - by Matthew Guay

  Would you like to correct errors in your ePub formatted eBooks, or even split them into chapters and create a Table of Contents?  Here’s how you can with the free program Sigil. eBooks are increasingly popular with the rise of eBook readers and reading apps on mobile devices.  We recently showed you how to convert a PDF eBook to ePub format, but as you may have noticed, sometimes the converted file had some glitches or odd formatting.  Additionally, many of the many free ePub books available online from sources like the Project Guttenberg do not include a table of contents.  Sigil is a free application for Windows, OS X, and Linux that lets you edit ePub files, so let’s look at how you can use it to improve your eBooks. Note: Sigil took several moments to open files in our tests, and froze momentarily when we maximized the window.  Sigil is currently pre-release software in active development, so we would expect the bugs to be worked out in future versions.  As usual, only install if you’re comfortable testing pre-release software. Getting Started Download Sigil (link below), making sure to select the correct version for your computer.  Run the installer, and select your preferred setup language when prompted. After a moment the installer will appear; setup as normal. Launch Sigil when it’s finished installing.  It opens with a default blank ePub file, so you could actually start writing an eBook from scratch right here. Edit Your ePub eBooks Now you’re ready to edit your ePub books.  Click Open and browse to the file you want to edit. Now you can double-click any of the HTML or XHTML files on the left sidebar and edit them just like you would in Word. Or you can choose to view it in Code View and edit the actual HTML directly. The sidebar also gives you access to the other parts of the ePub file, such as Images and CSS styles. If your ePub file has a Table of Contents, you can edit it with Sigil as well.  Click Tools in the menu bar, and then select TOC Editor.  Strangely there is no way to create a new table of contents, but you can remove entries from existing one.   Convert TXT Files to ePub Many free eBooks online, especially older, out of copyright titles, are available in plain text format.  One problem with these files is that they usually use hard returns at the end of lines, so they don’t reflow to fill your screen efficiently. Sigil can easily convert these files to the more useful ePub format.  Open the text file in Sigil, and it will automatically reflow the text and convert it ePub.  As you can see in the screenshot below, the text in the eBook does not have hard line-breaks at the end of each line, and will be much more readable on mobile devices. Note that Sigil may take several moments opening the book, and may even become unresponsive while analyzing it.   Now you can edit your eBook, split it into chapters, or just save it as is.  Either way, make sure to select Save as to save your book as ePub format. Conclusion As mentioned before, Sigil seems to run slow at times, especially when editing large eBooks.  But it’s still a nice solution to edit and extend your ePub eBooks, and even convert plain text eBooks to the nicer ePub format.  Now you can make your eBooks work just like you want, and read them on your favorite device! If you feel comfortable editing HTML files, check out our article on how to edit ePub eBooks with your favorite HTML editor.

• Oracle Service Bus duplicate message check using Coherence by Jan van Zoggel

  - by JuergenKress

  In a situation where you need some sort of duplicate message check for an Oracle Service Bus project you would need some custom code. Since the Oracle Service Bus is stateless, when it handles a proxy service call it will not know if this specific message was handled before. So there needs to be some sort of logic in your service for validating it’s a new unique message id. Read the full article here.

• Sending Big Files with WCF

  - by Sean Feldman

  I had to look into a project that submits large files to WCF service. Implementation is based on data chunking. This is a good approach when your client and server are not both based on WCF, bud different technologies. The problem with something like this is that chunking (either you wish it or not) complicates the overall solution. Alternative would be streaming. In WCF to WCF scenario, this is a piece of cake. When client is Java, it becomes a bit more challenging (has anyone implemented Java client streaming data to WCF service?). What I really liked about .NET implementation with WCF, is that sending header info along with stream was dead simple, and from the developer point of view looked like it’s all a part of the DTO passed into the service. [ServiceContract] public interface IFileUpload { [OperationContract] void UploadFile(SendFileMessage message); } Where SendFileMessage is [MessageContract] public class SendFileMessage { [MessageBodyMember(Order = 1)] public Stream FileData; [MessageHeader(MustUnderstand = true)] public FileTransferInfo FileTransferInfo; }

• Using Telerik Reporting in a WPF application

  Now that Telerik Reporting provides WPF support, let's see how to use it (a video is also available on Getting Started with the WPF viewer): Creating the application Install RadControls for WPF 2010 Q1 SP1 (download | release notes). Install the corresponding Telerik Reporting version. Create a new WPF application project in Visual Studio Add references to the following Telerik RadControls for WPF assemblies: Telerik.Windows.Controls Telerik.Windows.Controls.Input Telerik.Windows.Controls.Navigation Telerik.Windows.Data NOTE: It is possible that the RadControls for WPF assemblies have a greater version than the one against which the WPF Report Viewer control was built. In this case you have to add appropriate assembly binding redirects (see Binding Redirects bellow). Drag and drop the ReportViewer control from the toolbox in the WPF window. If the ReportViewer is not available in the toolbox, you can add it using the instructions from the How to add the WPF ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• Review of ComponentOne Silverlight Controls (Free License Giveaway).

  - by mbcrump

  ComponentOne has several great products that target Silverlight Developers. One of them is their Silverlight Controls and the other is the XAP Optimizer. I decided that I would check out the controls and Xap Optimizer and feature them on my blog. After talking with ComponentOne, they agreed to take part in my Monthly Silverlight giveaway. The details are listed below: ----------------------------------------------------------------------------------------------------------------------------------------------------------- Win a FREE developer’s license of ComponentOne Silverlight Controls + XAP Optimizer! (the winner also gets a license to Silverlight Spy) Random winner will be announced on March 1st, 2011! To be entered into the contest do the following things: Subscribe to my feed. Leave a comment below with a valid email account (I WILL NOT share this info with anyone.) Retweet the following : I just entered to win free #Silverlight controls from @mbcrump and @ComponentOne http://mcrump.me/fTSmB8 ! Don’t change the URL because this will allow me to track the users that Tweet this page. Don’t forget to visit ComponentOne because they made this possible. MichaelCrump.Net provides Silverlight Giveaways every month. You can also see the latest giveaway by bookmarking http://giveaways.michaelcrump.net . ---------------------------------------------------------------------------------------------------------------------------------------------------------- Before we get started with the Silverlight Controls, here is a couple of links to bookmark: The Live Demos of the Silverlight Controls is located here. The XAP Optimizer page is here. One thing that I liked about the help documentation is that you can grab a PDF that only contains documentation for that control. This allows you to get the information you need without going through several hundred pages. You can also download the full documentation from their site.  ComponentOne Silverlight Controls I recently built a hobby project and decided to use ComponentOne Silverlight Controls. The main reason for this is that the controls are heavily documented, they look great and getting help was just a tweet or forum click away. So, the first question that you may ask is, “What is included?” Here is the official list below. I wanted to show several of the controls that I think developers will use the most. 1) ComponentOne’s Image Control – Display animated GIF images on your Silverlight pages as you would in traditional Web apps. Add attractive visuals with minimal effort. 2) HTML Host - Render HTML and arbitrary URI content from within Silverlight. 3) Chart3D - Create 3D surface charts with options for contour levels, zones, a chart legend and more. 4) PDFViewer - View PDF files in Silverlight! That is just a fraction of the controls available. If you want to check out several of them in a “real” application then check out my Silverlight page at http://michaelcrump.info. This brings me to the second part of the giveaway. XAP Optimizer – Is designed to reduce the size of your XAP File. It also includes built-in obfuscation and signing. With my personal project, I decided to use the XAP Optimizer by ComponentOne. It was so easy to use. You basically give it your .XAP file and it provides an output file. If you prefer to prune unused references manually then you can prune your XAP file manually by selecting the option below. I went ahead and added Obfuscation just to try it out and it worked great. You may notice from the screenshot below that I only obfuscated assemblies that I built. The other dlls anyone can grab off the net so we have no reason to obfuscate them. You also have the option to automatically sign your .xap with the SN.exe tool. So how did it turn out? Well, I reduced my XAP size from 2.4 to 1.8 with simply a click of a button. I added obfuscation with a click of a button: Screenshot of no obfuscation on my XAP File   Screenshot of obfuscation on my XAP File with XAP Optimizer.   So, with 2 button clicks, I reduce my XAP file and obfuscated my assembly. What else can you want? Well, they provide a nice HTML report that gives you an optimization summary. So what if you don’t want to launch this tool every time you deploy a Silverlight application? Well the official documentation provided a way to do it in your built event in Visual Studio. Click the Build Events tab on the left side of the Properties window. Enter the following command in the Post-build event command line: $Program Files\ComponentOne\XapOptimizer\XapOptimizer.exe /cmd /p:$(ProjectDir)$(ProjectName).xoproj In the end, this is a great product. I love code that I don’t have to write and utilities that just work. ComponentOne delivers with both the Silverlight Controls and the XAP Optimizer. Don’t forget to leave a comment below in order to win a set of the controls! Subscribe to my feed

• How do you guys handle translation for software localization?

  - by JohnFx

  Most of the software I have written over my career has been built for English speaking customers, but recently I've been working on a project where localization of the UI for a wider range of languages is desired. I am just curious how other programming shops obtain the translations. Do they use the notoriously flawed online translation engines? I know there are for-hire translators out there, but am I going to have to track down and contract like a dozen of them to do a thorough job of localizing my interface? Are there services that specialize in doing this for a wide range of languages? Perhaps using something like Amazon's Mechanical Turk would be an option, but I have no idea how diverse the available workforce is on that site. I'd imagine not very.

• Sitefinity SimpleImageSelector to return Url of image instead of Guid

  - by Joey Brenn

  It's been quite a while but I've found something to blog about!I've been working with Sitefinity for some time now and one of the things that I've struggled with, and I'm not the only one is something that should be simple.  See, all I want to do is be able to choose a picture from one of the libraries within Sitefinity and be able to display it via the GUID it returns or the path of the URL.  I want to do this from my user control or a custom control.Well, it turns out that this is not built in, at least I've not been able to get anything working correctly until I found this post and was able to get it to work.  However, I want to store the relative URL of the image so I made a small change to make it return the URL instead of the GUID.To make the change, in the SimpleImageSelectorDialog.js file, on line 43, change the original line:var selectedValue = this.get_imageSelector().get_selectedImageId();to the new line:var selectedValue = this.get_imageSelector().get_selectedImageUrl();var selectedValue = this.get_imageSelector().get_selectedImageUrl();Of course, save and recomple the project and now it will return the URL instead of the GUID of the image from the choosen Album.

• Monitoring ASP.NET Application

  - by imran_ku07

      Introduction:          There are times when you may need to monitor your ASP.NET application's CPU and memory consumption, so that you can fine-tune your ASP.NET application(whether Web Form, MVC or WebMatrix). Also, sometimes you may need to see all the exceptions(and their details) of your application raising, whether they are handled or not. If you are creating an ASP.NET application in .NET Framework 4.0, then you can easily monitor your application's CPU or memory consumption and see how many exceptions your application raising. In this article I will show you how you can do this.       Description:           With .NET Framework 4.0, you can turn on the monitoring of CPU and memory consumption by setting AppDomain.MonitoringEnabled property to true. Also, in .NET Framework 4.0, you can register a callback method to AppDomain.FirstChanceException event to monitor the exceptions being thrown within your application's AppDomain. Turning on the monitoring and registering a callback method will add some additional overhead to your application, which will hurt your application performance. So it is better to turn on these features only if you have following properties in web.config file,   <add key="AppDomainMonitoringEnabled" value="true"/> <add key="FirstChanceExceptionMonitoringEnabled" value="true"/>             In case if you wonder what does FirstChanceException mean. It simply means the first notification of an exception raised by your application. Even CLR invokes this notification before the catch block that handles the exception. Now just update global.asax.cs file as,   string _item = "__RequestExceptionKey"; protected void Application_Start() { SetupMonitoring(); } private void SetupMonitoring() { bool appDomainMonitoringEnabled, firstChanceExceptionMonitoringEnabled; bool.TryParse(ConfigurationManager.AppSettings["AppDomainMonitoringEnabled"], out appDomainMonitoringEnabled); bool.TryParse(ConfigurationManager.AppSettings["FirstChanceExceptionMonitoringEnabled"], out firstChanceExceptionMonitoringEnabled); if (appDomainMonitoringEnabled) { AppDomain.MonitoringIsEnabled = true; } if (firstChanceExceptionMonitoringEnabled) { AppDomain.CurrentDomain.FirstChanceException += (object source, FirstChanceExceptionEventArgs e) => { if (HttpContext.Current == null)// If no context available, ignore it return; if (HttpContext.Current.Items[_item] == null) HttpContext.Current.Items[_item] = new RequestException { Exceptions = new List<Exception>() }; (HttpContext.Current.Items[_item] as RequestException).Exceptions.Add(e.Exception); }; } } protected void Application_EndRequest() { if (Context.Items[_item] != null) { //Only add the request if atleast one exception is raised var reqExc = Context.Items[_item] as RequestException; reqExc.Url = Request.Url.AbsoluteUri; Application.Lock(); if (Application["AllExc"] == null) Application["AllExc"] = new List<RequestException>(); (Application["AllExc"] as List<RequestException>).Add(reqExc); Application.UnLock(); } }               Now browse to Monitoring.cshtml file, you will see the following screen,                            The above screen shows you the total bytes allocated, total bytes in use and CPU usage of your application. The above screen also shows you all the exceptions raised by your application which is very helpful for you. I have uploaded a sample project on github at here. You can find Monitoring.cshtml file on this sample project. You can use this approach in ASP.NET MVC, ASP.NET WebForm and WebMatrix application.       Summary:          This is very important for administrators/developers to manage and administer their web application after deploying to production server. This article will help administrators/developers to see the memory and CPU usage of their web application. This will also help administrators/developers to see all the exceptions your application is throwing whether they are swallowed or not. Hopefully you will enjoy this article too.   SyntaxHighlighter.all()

• Upgrading ASP.NET AJAX 1.0 Websites to .NET 4.5

  - by Lijo

  I have an existing website in ASP.Net 2.0 that uses ASP.Net Ajax 1.0. This is developed using Visual Studio 2005. Now, we are planning to upgrade this to .Net 4.5 and VS2013. When I made a search, I could see that there are blogs about upgrading projects with Ajax 1.0 to .Net 3.5 version. However I could not find useful links for upgrading to .Net 4.5. Do we have any useful links for that? Or is it an unworkable approach? Note: As of now we have not purchased VS2013 and servers for this. Purchase depends on the feasibility study. Hence I cannot test it myself, at present. Upgrading ASP.NET AJAX 1.0 Websites and Web Applications to .NET Framework 3.5 How To: Upgrade an ASP.NET AJAX 1.0 Web Project to .NET Framework 3.5

• Adaptative interface with Open GL and machine learning in C#

  - by Afnan

  For my Semester project I have to go for any Adaptative Interface Design. My language is C# and I have to Use OpenTK (wrapper for OpenGL). I have an idea that I should show two points and some obstacles and my subject (user) would drag an object from one place to the final place avoiding the Obstacles. Also (s)he can place obstacles randomly. My software should be able to learn some paths by doing test runs and then after learning it should be able to predict the shortest path. I do not know how stupid this idea sounds but it is just an idea. I need help regarding any ideas for adaptative interface possible small projects or if my idea is ok then please can you tell me what should be used to implement it? I mean that along with OpenGl for the Graphics what can I use for machine learning?

• How to measure code quality? [closed]

  - by Lo Wai Lun

  Is there a methodology or any objective standard to determine whether the code of the project is well-written? How to measure in a structural and scientific manner to access the quality of the code? Many people say code review is important and always do encapsulation and data abstraction to ensure the quality. How can we determine the quality? Can a structural, organised software design diagrams drawn implies good quality of code ? If we type the code with good cautions of encapsulation and data abstraction, why review anyway?

• Integrating Code Metrics in TFS 2010 Build

  - by Jakob Ehn

  The build process template and custom activity described in this post is available here: http://cid-ee034c9f620cd58d.office.live.com/self.aspx/BlogSamples/CodeMetricsSample.zip Running code metrics has been available since VS 2008, but only from inside the IDE. Yesterday Microsoft finally releases a Visual Studio Code Metrics Power Tool 10.0, a command line tool that lets you run code metrics on your applications.  This means that it is now possible to perform code metrics analysis on the build server as part of your nightly/QA builds (for example). In this post I will show how you can run the metrics command line tool, and also a custom activity that reads the output and appends the results to the build log, and also fails he build if the metric values exceeds certain (configurable) treshold values. The code metrics tool analyzes all the methods in the assemblies, measuring cyclomatic complexity, class coupling, depth of inheritance and lines of code. Then it calculates a Maintainability Index from these values that is a measure f how maintanable this method is, between 0 (worst) and 100 (best). For information on hwo this value is calculated, see http://blogs.msdn.com/b/codeanalysis/archive/2007/11/20/maintainability-index-range-and-meaning.aspx. After this it aggregates the information and present it at the class, namespace and module level as well. Running Metrics.exe in a build definition Running the actual tool is easy, just use a InvokeProcess activity last in the Compile the Project sequence, reference the metrics.exe file and pass the correct arguments and you will end up with a result XML file in the drop directory. Here is how it is done in the attached build process template: In the above sequence I first assign the path to the code metrics result file ([BinariesDirectory]\result.xml) to a variable called MetricsResultFile, which is then sent to the InvokeProcess activity in the Arguments property. Here are the arguments for the InvokeProcess activity: Note that we tell metrics.exe to analyze all assemblies located in the Binaries folder. You might want to do some more intelligent filtering here, you probably don’t want to analyze all 3rd party assemblies for example. Note also the path to the metrics.exe, this is the default location when you install the Code Metrics power tool. You must of course install the power tool on all build servers. Using the standard output logging (in the Handle Standard Output/Handle Error Output sections), we get the following output when running the build: Integrating Code Metrics into the build Having the results available next to the build result is nice, but we want to have results integrated in the build result itself, and also to affect the outcome of the build. The point of having QA builds that measure, for example, code metrics is to make it very clear how the code being built measures up to the standards of the project/company. Just having a XML file available in the drop location will not cause the developers to improve their code, but a (partially) failing build will! To do this, we need to write a custom activity that parses the metrics result file, logs it to the build log and fails the build if the values frfom the metrics is below/above some predefined treshold values. The custom activity performs the following steps Parses the XML. I’m using Linq 2 XSD for this, since the XML schema for the result file is available, it is vey easy to generate code that lets you query the structure using standard Linq operators. Runs through the metric result hierarchy and logs the metrics for each level and also verifies maintainability index and the cyclomatic complexity with the treshold values. The treshold values are defined in the build process template are are sent in as arguments to the custom activity If the treshold values are exceeded, the activity either fails or partially fails the current build. For more information about the structure of the code metrics result file, read Cameron Skinner's post about it. It is very simpe and easy to understand. I won’t go through the code of the custom activity here, since there is nothing special about it and it is available for download so you can look at it and play with it yourself. The treshold values for Maintainability Index and Cyclomatic Complexity is defined in the build process template, and can be modified per build definition: I have taken the default value for these settings from my colleague Terje Sandström post on Code Metrics - suggestions for approriate limits. You’ll notice that this is quite an improvement compared to using code metrics inside the IDE, where Red/Yellow/Green limits are fixed (and the default values are somewaht strange, see Terjes post for a discussion on this) This is the first version of the code metrics integration with TFS 2010 Build, I will proabably enhance the functionality and the logging (the “tree view” structure in the log becomes quite hard to read) soon. I will also consider adding it to the Community TFS Build Extensions site when it becomes a bit more mature. Another obvious improvement is to extend the data warehouse of TFS and push the metric results back to the warehouse and make it visible in the reports.

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

  - by Jon Galloway

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