  • Documenting sp_ssiscatalog

    - by jamiet
    What is the best way to document an API? Moreover, what is the best way to document a T-SQL API? Before I try to answer those questions I should explain what I mean by “a T-SQL API”. I think of an API as being a collection of well-defined, known, code modules that provide some notion of a service to whomever uses it; in T-SQL terms I tend to think of a collection of stored procedures and functions as a form of API. Its a loose definition, I admit, and in SQL Server circles we don’t tend to think of stored procedures collectively as an API but if you think about it that’s exactly what they are. The question of how to document a T-SQL API came to my mind as I worked on sp_ssiscatalog. How could I make it easy for people to learn about the capabilities of sp_ssiscatalog without forcing them to dig through the code and find out for themselves? My opening gambit was to write documentation pages on the wiki at http://ssisreportingpack.codeplex.com. That’s kinda useful but it does suffer the disadvantage that someone using sp_ssiscatalog needs to go visit a webpage to read it – I want the documentation to be available wherever the user is using sp_ssiscatalog. Moreover, maintaining the wiki is a real PITA. Intellisense works up to a point, I guess: but that only shows whatever SQL Server knows about the various parameters, which isn’t all that much! I wanted a better way for my API users to learn about its capabilities and so I hit upon the idea of simply using PRINT statements within the code itself to inform the user what options are available; hence I added such PRINT statements in the latest check-in. Now when you execute (for example): EXEC sp_ssiscatalog @operation_type='execs' you can hit F6 a few times to view the messages pane and you shall see something like this: Notice that I’m returning information about all the parameters that can be used to affect the results that just got returned. I really do think this will be very useful to anyone using sp_ssiscatalog; I myself am always forgetting what the parameters are and I wrote the damn thing so I can’t really expect anyone else to remember them. I have not yet made available a release that has these changes in it but when I do I’ll blog about it right here. At the time of writing the latest available release of sp_ssiscatalog is DB v1.0.1.0 but if you want to the latest and greatest simply download it straight from source. Feedback is welcome as always. @Jamiet

  • LINQ to Twitter v2.1.09 Released

    - by Joe Mayo
    Originally posted on: http://geekswithblogs.net/WinAZ/archive/2013/10/15/linq-to-twitter-v2.1.09-released.aspxToday, I released LINQ to Twitter v2.1.09. Here are important new changes. Bug Fixes This is primarily a bug fix release. Most notably, there were authentication problems in WinRT apps. This is now fixed. New Features One new feature is the addition of ApplicationOnlyAuthentication for WinRT. It is fully async.  Here’s how it works: var auth = new WinRtApplicationOnlyAuthorizer { Credentials = new InMemoryCredentials { ConsumerKey = "", ConsumerSecret = "" } }; if (auth == null || !auth.IsAuthorized) { await auth.AuthorizeAsync(); } var twitterCtx = new TwitterContext(auth); (from search in twitterCtx.Search where search.Type == SearchType.Search && search.Query == SearchTextBox.Text select search) .MaterializedAsyncCallback( async response => await Dispatcher.RunAsync( CoreDispatcherPriority.Normal, async () => { Search searchResponse = response.State.Single(); string message = string.Format( "Search returned {0} statuses", searchResponse.Statuses.Count); await new MessageDialog(message, "Search Complete").ShowAsync(); })); It’s called the WinRtApplicationOnlyAuthorizer. You only need two tokens, ConsumerKey and ConsumerSecret, which come from your Twitter API application settings page. Note: You need a Twitter Application, which you can create at https://dev.twitter.com/. The MaterializedAsyncCallback materializes your query and handles the response. I put everything together in a lambda for demonstration purposes, but you can always replace the callback with a handler of type Action<TwitterAsyncResponse<IEnumerable<T>>>, where T is Search for this example. On the Horizon The next version of LINQ to Twitter is in development. I discussed it at LINQ to Twitter Async. This isn’t complete, but you can download the source code at the LINQ to Twitter site on CodePlex. I’ve competed all the spikes for what I thought would be the hard parts and now have prototypes of queries and commands working. This would be a good time to provide feedback if there are features in the current version that you think could be improved. The current driving forces for the next version will be async and PCL.   @JoeMayo

  • From 20,663 issues to 1 issue&ndash;style-copping C5.Tests

    - by TATWORTH
    Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2014/05/28/from-20663-issues-to-1-issuendashstyle-copping-c5.tests.aspxI recently became interested in the potential of the C5 Collections solution from http://www.itu.dk/research/c5/, however I was dismayed at the state of the code in the unit test project, so I set about fixing the 20,663 issues detected by StyleCop. The tools I used were the latest versions of: My 64-bit development PC running Windows 8 Update with 8Gb RAM Visual Studio 2013 Ultimate with SP2 ReSharper GhostDoc Pro My first attempt had to be abandoned due to collision of class names which broke one of the unit tests. So being aware of this duplication of class names, I started again and planned to prepend the class names with the namespace name. In some cases I additionally prepended the item of the C5 collection that was being tested. So what was the condition of code at the start? Besides the sprawl of C# code not written to style cop standard, there was: 1) Placing of many classes within one physical file. 2) Namespace within name space that did not follow the project structure. 3) As already mentioned, duplication of class names across namespaces. 4) A copyright notice that spawled but had to be preserved. 5) Project sub-folders were all lower case instead of initial letter capitalised. The first step was to add a stylecop heading plus the original heading contained within a region, to every file. The next step was to run GhostDoc Pro using its “Document File” option on every file but not letting it replace the headers, I had added. This brought the number of issues down to 18,192. I then went through each file collapsing each class and prepending names as appropriate. At each step, I saved the changes to my local Git. The step was to move each class to its own file and to style-cop each file. ReSharper provides a very useful feature for doing this which also fixes missing “this.” and moves using statements inside the namespace. Some classes required minimal work whereas others required extensive work to reach the stylecop standard. The unit tests were run at each split and when each class was completed. When all was done, one issue remained which I will need to submit to stylecop team for their advice (and possibly a fix to stylecop). The updated solution has been made available at https://c5stylecopped.codeplex.com/releases/view/122785.

  • Ionic Isapi Rewrite error on IIS6, Windows 2003 Server

    - by EsiX
    First of all my setup is a VPS running Windows 2003 Server with multiple domains on it IIS 6, Plesk IsapiRewrite4.ini RewriteLogLevel 3 RewriteCond %{HTTP_HOST} ^mydomain.com$ RewriteRule ^/(.*)$ http://www.mydomain.com/$1 [R] This is one of their basic examples. Ionic is installed and setup proper because if I use another rule (a simpler one ... like the one following) it works instant # IsapiRewrite4.ini # RewriteLogLevel 3 # # This ini file illustrates the use of a redirect rule. # Any incoming URL that starts with an uppercase W # will be redirected to the specified server. RewriteRule ^/(W.*)$ http://server.dyndns.org:7070/$1 [R] This one works in the TestDriver tool and none of them gives any error or warnings in TestParse tool, but it doesn't do a thing on the webserver... The fact that one rule works means that the isapi module works. I am using the last version. RedirectRule http://mydomain.com/someplace/somefile.html http://www.mydomain.com/howto/someplace/anotherfile.html [I,L] Both examples were taken from http://iirf.codeplex.com/Wiki/View.aspx?title=Redirection&referringTitle=Home So my IsapiRewrite4.ini needs to do this two tasks: auto transform and redirection for a number of urls. Can you help out.. I really don't know what I'm doing wrong.

  • Code to update HyperV Export file

    - by Andy Schneider
    I am using the HyperV Module from Codeplex to do a "config only" export from a 2008R2 Hyper-V server. In order to import the configuration on another HyperV server, I need to edit the value of CopyVMStorage in the EXP file. This file is an XML file. I wrote the following code in PowerShell to do the update for me. The variable $existing is the existing exp file. $xml = [xml](get-content $existing) $xpath = '//PROPERTY[@NAME ="CopyVmStorage"]' foreach ($node in $xml.SelectNodes($xpath)) {$node.Value = 'TRUE'} $xml.Save($existing) This code makes the correct changes to the XML. However, when I go to import the file on the Hyper-V server, I get an error that says the file format is incorrect. I am wondering if the encoding of the file is incorrect or if there is something else going on. If I edit the file manually in wordpad, it imports without an issue. The filename is a GUID with a .exp extension, and it appears that the file name is too long for notepad to open. Notepad throws an error trying to open the file, which is why I went with WordPad. I have noticed that the file that is updated with PowerShell comes out formatted whereas the raw file is xml all bunched together with no whitespace. Any ideas on what "file format" means in this HyperV error message and how I might be able to use my code to automate this change in the XML without changing the file format?

  • Possible disk IO issue

    - by Tim Meers
    I've been trying to really figure out what my IOPS are on my DB server array and see if it's just too much. The array is four 72.6gb 15k rpm drives in RAID 5. To calculate IOPS for RAID 5 the following formula is used: (reads + (4 * Writes)) / Number of disks = total IOPS. The formula is from MSDN. I also want to calculate the Avg Queue Length but I'm not sure where they are getting the formula from, but i think it reads on that page as avg que length/number of disks = actual queue. To populate that formula I used the perfmon to gather the needed information. I came up with this, under normal production load: (873.982 + (4 * 28.999)) / 4 = 247.495. Also the disk queue lengh of 14.454/4 = 3.614. So to the question, am I wrong in thinking this array has a very high disk IO? Edit I got the chance to review it again this morning under normal/high load. This time with even bigger numbers and IOPS in excess of 600 for about 5 minutes then it died down again. But I also took a look at the Avg sec/Transfer, %Disk Time, and %Idle Time. These number were taken when the reads/writes per sec were only 332.997/17.999 respectively. %Disk Time: 219.436 %Idle Time: 0.300 Avg Disk Queue Length: 2.194 Avg Disk sec/Transfer: 0.006 Pages/sec: 2927.802 % Processor Time: 21.877 Edit (again) Looks like I have that issue solved. Thanks for the help. Also for a pretty slick parser I found this: http://pal.codeplex.com/ It works pretty well for breaking down the data into something usable.

  • SQLAuthority News – Guest Post – Performance Counters Gathering using Powershell

    - by pinaldave
    Laerte Junior Laerte Junior has previously helped me personally to resolve the issue with Powershell installation on my computer. He did awesome job to help. He has send this another wonderful article regarding performance counter for readers of this blog. I really liked it and I expect all of you who are Powershell geeks, you will like the same as well. As a good DBA, you know that our social life is restricted to a few movies over the year and, when possible, a pizza in a restaurant next to your company’s place, of course. So what we have to do is to create methods through which we can facilitate our daily processes to go home early, and eventually have a nice time with our family (and not sleeping on the couch). As a consultant or fixed employee, one of our daily tasks is to monitor performance counters using Perfmom. To be honest, IDE is getting more complicated. To deal with this, I thought a solution using Powershell. Yes, with some lines of Powershell, you can configure which counters to use. And with one more line, you can already start collecting data. Let’s see one scenario: You are a consultant who has several clients and has just closed another project in troubleshooting an SQL Server environment. You are to use Perfmom to collect data from the server and you already have its XML configuration files made with the counters that you will be using- a file for memory bottleneck f, one for CPU, etc. With one Powershell command line for each XML file, you start collecting. The output of such a TXT file collection is set to up in an SQL Server. With two lines of command for each XML, you make the whole process of data collection. Creating an XML configuration File to Memory Counters: Get-PerfCounterCategory -CategoryName "Memory" | Get-PerfCounterInstance  | Get-PerfCounterCounters |Save-ConfigPerfCounter -PathConfigFile "c:\temp\ConfigfileMemory.xml" -newfile Creating an XML Configuration File to Buffer Manager, counters Page lookups/sec, Page reads/sec, Page writes/sec, Page life expectancy: Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters -CounterName "Page*" | Save-ConfigPerfCounter -PathConfigFile "c:\temp\BufferManager.xml" –NewFile Then you start the collection: Set-CollectPerfCounter -DateTimeStart "05/24/2010 08:00:00" -DateTimeEnd "05/24/2010 22:00:00" -Interval 10 -PathConfigFile c:\temp\ConfigfileMemory.xml -PathOutputFile c:\temp\ConfigfileMemory.txt To let the Buffer Manager collect, you need one more counters, including the Buffer cache hit ratio. Just add a new counter to BufferManager.xml, omitting the new file parameter Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters -CounterName "Buffer cache hit ratio" | Save-ConfigPerfCounter -PathConfigFile "c:\temp\BufferManager.xml" And start the collection: Set-CollectPerfCounter -DateTimeStart "05/24/2010 08:00:00" -DateTimeEnd "05/24/2010 22:00:00" -Interval 10 -PathConfigFile c:\temp\BufferManager.xml -PathOutputFile c:\temp\BufferManager.txt You do not know which counters are in the Category Buffer Manager? Simple! Get-PerfCounterCategory -CategoryName "SQLServer:Buffer Manager" | Get-PerfCounterInstance | Get-PerfCounterCounters Let’s see one output file as shown below. It is ready to bulk insert into the SQL Server. As you can see, Powershell makes this process incredibly easy and fast. Do you want to see more examples?

  • Start Learning Ruby with IronRuby – Setting up the Environment

    - by kazimanzurrashid
    Recently I have decided to learn Ruby and for last few days I am playing with IronRuby. Learning a new thing is always been a fun and when it comes to adorable language like Ruby it becomes more entertaining. Like any other language, first we have to create the development environment. In order to run IronRuby we have to download the binaries form the IronRuby CodePlex project. IronRuby supports both .NET 2.0 and .NET 4, but .NET 4 is the recommended version, you can download either the installation or the zip file. If you download the zip file make sure you added the bin directory in the environment path variable. Once you are done, open up the command prompt and type : ir –v It should print message like: IronRuby 1.0.0.0 on .NET 4.0.30319.1 The ir is 32bit version of IronRuby, if you want to use 64bit you can try ir64. Next, we have to find a editor where we can write our Ruby code as there is currently no integration story of IronRuby with Visual Studio like its twin Iron Python. Among the free IDEs only SharpDevelop has the IronRuby support but it does not have auto complete or debugging built into it, only thing that it supports is the syntax highlighting, so using a text editor which has the same features is nothing different comparing to it. To play with the IronRuby we will be using Notepad++, which can be downloaded from its sourceforge download page. The Notepad++ does have a nice syntax highlighting support : I am using the Vibrant Ink with some little modification. The next thing we have to do is configure the Notepad++ that we can run the Ruby script in IronRuby inside the Notepad++. Lets create a batch(.bat) file in the IronRuby bin directory, which will have the following content: @echo off  cls call ir %1 pause This will make sure that the console will be paused once we run the script. Now click Run->Run in the Notepad++, it will bring up the run dialog and put the following command in the textbox: riir.bat "$(FULL_CURRENT_PATH)" Click the save which will bring another dialog. Type Iron Ruby and assign the shortcut to ctrl + f5 (Same as Visual Studio Start without Debugging) and click ok. Once you are done you will find the IronRuby in the Run menu. Now press ctrl + f5, we will find the ruby script running in the IronRuby. Now there are one last thing that we would like to add which is poor man’s context sensitive help. First, download the ruby language help file from the Ruby Installer site and extract into a directory. Next we will have to install the Language Help Plug-in of Notepad++, click Plugins->Plugin Manger –>Show Plugin Manager and scroll down until you find the plug-in the list, now check the plug-in and click install. Once it is installed it will prompt you to restart the Notepad++, click yes. When the Notepad++ restarts, click the Plugins –> Language Help –> Options –> add and enter the following details and click ok: The chm file location can be different depending upon where you extracted it. Now when you put your in any of ruby keyword and press ctrl + f1 it will take you to the help topic of that keyword. For example, when my caret is in the each of the following code and I press ctrl + f1, it will take me to the each api doc of Array. def loop_demo (1..10).each{ |n| puts n} end loop_demo That’s it for today. Happy Ruby coding.

  • Java Resources for Windows Azure

    - by BuckWoody
    Windows Azure is a Platform as a Service – a PaaS – that runs code you write. That code doesn’t just mean the languages on the .NET platform – you can run code from multiple languages, including Java. In fact, you can develop for Windows and SQL Azure using not only Visual Studio but the Eclipse Integrated Development Environment (IDE) as well.  Although not an exhaustive list, here are several links that deal with Java and Windows Azure: Resource Link Windows Azure Java Development Center http://www.windowsazure.com/en-us/develop/java/  Java Development Guidance http://msdn.microsoft.com/en-us/library/hh690943(VS.103).aspx  Running a Java Environment on Windows Azure http://blogs.technet.com/b/port25/archive/2010/10/28/running-a-java-environment-on-windows-azure.aspx  Running a Java Environment on Windows Azure http://blogs.technet.com/b/port25/archive/2010/10/28/running-a-java-environment-on-windows-azure.aspx  Run Java with Jetty in Windows Azure http://blogs.msdn.com/b/dachou/archive/2010/03/21/run-java-with-jetty-in-windows-azure.aspx  Using the plugin for Eclipse http://blogs.msdn.com/b/craig/archive/2011/03/22/new-plugin-for-eclipse-to-get-java-developers-off-the-ground-with-windows-azure.aspx  Run Java with GlassFish in Windows Azure http://blogs.msdn.com/b/dachou/archive/2011/01/17/run-java-with-glassfish-in-windows-azure.aspx  Improving experience for Java developers with Windows  Azure http://blogs.msdn.com/b/interoperability/archive/2011/02/23/improving-experience-for-java-developers-with-windows-azure.aspx  Java Access to SQL Azure via the JDBC Driver for SQL  Server http://blogs.msdn.com/b/brian_swan/archive/2011/03/29/java-access-to-sql-azure-via-the-jdbc-driver-for-sql-server.aspx  How to Get Started with Java, Tomcat on Windows Azure http://blogs.msdn.com/b/usisvde/archive/2011/03/04/how-to-get-started-with-java-tomcat-on-windows-azure.aspx  Deploying Java Applications in Azure http://blogs.msdn.com/b/mariok/archive/2011/01/05/deploying-java-applications-in-azure.aspx  Using the Windows Azure Storage Explorer in Eclipse http://blogs.msdn.com/b/brian_swan/archive/2011/01/11/using-the-windows-azure-storage-explorer-in-eclipse.aspx  Windows Azure Tomcat Solution Accelerator http://archive.msdn.microsoft.com/winazuretomcat  Deploying a Java application to Windows Azure with  Command-line Ant http://java.interoperabilitybridges.com/articles/deploying-a-java-application-to-windows-azure-with-command-line-ant  Video: Open in the Cloud: Windows Azure and Java http://channel9.msdn.com/Events/PDC/PDC10/CS10  AzureRunMe  http://azurerunme.codeplex.com/  Windows Azure SDK for Java http://www.interoperabilitybridges.com/projects/windows-azure-sdk-for-java  AppFabric SDK for Java http://www.interoperabilitybridges.com/projects/azure-java-sdk-for-net-services  Information Cards for Java http://www.interoperabilitybridges.com/projects/information-card-for-java  Apache Stonehenge http://www.interoperabilitybridges.com/projects/apache-stonehenge  Channel 9 Case Study on Java and Windows Azure http://www.microsoft.com/casestudies/Windows-Azure/Gigaspaces/Solution-Provider-Streamlines-Java-Application-Deployment-in-the-Cloud/400000000081

  • FluentPath: a fluent wrapper around System.IO

    - by Bertrand Le Roy
    .NET is now more than eight years old, and some of its APIs got old with more grace than others. System.IO in particular has always been a little awkward. It’s mostly static method calls (Path.*, Directory.*, etc.) and some stateful classes (DirectoryInfo, FileInfo). In these APIs, paths are plain strings. Since .NET v1, lots of good things happened to C#: lambda expressions, extension methods, optional parameters to name just a few. Outside of .NET, other interesting things happened as well. For example, you might have heard about this JavaScript library that had some success introducing a fluent API to handle the hierarchical structure of the HTML DOM. You know? jQuery. Knowing all that, every time I need to use the stuff in System.IO, I cringe. So I thought I’d just build a more modern wrapper around it. I used a fluent API based on an essentially immutable Path type and an enumeration of such path objects. To achieve the fluent style, a healthy dose of lambda expressions is being used to act on the objects. Without further ado, here’s an example of what you can do with the new API. In that example, I’m using a Media Center extension that wants all video files to be in their own folder. For that, I need a small tool that creates directories for each video file and moves the files in there. Here’s the code for it: Path.Get(args[0]) .Select(p => p.Extension == ".avi" || p.Extension == ".m4v" || p.Extension == ".wmv" || p.Extension == ".mp4" || p.Extension == ".dvr-ms" || p.Extension == ".mpg" || p.Extension == ".mkv") .CreateDirectory(p => p.Parent .Combine(p.FileNameWithoutExtension)) .Previous() .Move(p => p.Parent .Combine(p.FileNameWithoutExtension) .Combine(p.FileName)); This code creates a Path object pointing at the path pointed to by the first command line argument of my executable. It then selects all video files. After that, it creates directories that have the same names as each of the files, but without their extension. The result of that operation is the set of created directories. We can now get back to the previous set using the Previous method, and finally we can move each of the files in the set to the corresponding freshly created directory, whose name is the combination of the parent directory and the filename without extension. The new fluent path library covers a fair part of what’s in System.IO in a single, convenient API. Check it out, I hope you’ll enjoy it. Suggestions are more than welcome. For example, should I make this its own project on CodePlex or is this informal style just OK? Anything missing that you’d like to see? Is there a specific example you’d like to see expressed with the new API? Bugs? The code can be downloaded from here (this is under a new BSD license): http://weblogs.asp.net/blogs/bleroy/Samples/FluentPath.zip

  • How to reproject a shapefile from WGS 84 to Spherical/Web Mercator projection.

    - by samkea
    Definitions: You will need to know the meaning of these terms below. I have given a small description to the acronyms but you can google and know more about them. #1:WGS-84- World Geodetic Systems (1984)- is a standard reference coordinate system used for Cartography, Geodesy and Navigation. #2: EPGS-European Petroleum Survey Group-was a scientific organization with ties to the European petroleum industry consisting of specialists working in applied geodesy, surveying, and cartography related to oil exploration. EPSG::4326 is a common coordinate reference system that refers to WGS84 as (latitude, longitude) pair coordinates in degrees with Greenwich as the central meridian. Any degree representation (e.g., decimal or DMSH: degrees minutes seconds hemisphere) may be used. Which degree representation is used must be declared for the user by the supplier of data. So, the Spherical/Web Mercator projection is referred to as EPGS::3785 which is renamed to EPSG:900913 by google for use in googlemaps. The associated CRS(Coordinate Reference System) for this is the "Popular Visualisation CRS / Mercator ". This is the kind of projection that is used by GoogleMaps, BingMaps,OSM,Virtual Earth, Deep Earth excetra...to show interactive maps over the web with thier nearly precise coordinates.  Reprojection: After reading alot about reprojecting my coordinates from the deepearth project on Codeplex, i still could not do it. After some help from a colleague, i got my ball rolling.This is how i did it. #1 You need to download and open your shapefile using Q-GIS; its the one with the biggest number of coordinate reference systems/ projections. #2 Use the plugins menu, and enable ftools and the WFS plugin. #3 Use the Vector menu--> Data Management Tools and choose define current projection. Enable, use predefined reference system and choose WGS 84 coodinate system. I am personally in zone 36, so i chose WGS84-UTM Zone 36N under ( Projected Coordinate Systems--> Universal Transverse Mercator) and click ok. #4 Now use the Vector menu--> Data Management Tools and choose export to new projection. The same dialog will pop-up. Now choose WGS 84 EPGS::4326 under Geodetic Coordinate Systems. My Input user Defined Spatial Reference System should looks like this: +proj=tmerc +lat_0=0 +lon_0=33 +k=0.9996 +x_0=500000 +y_0=200000 +ellps=WGS84 +datum=WGS84 +units=m +no_defs Your Output user Defined Spatial Reference System should look like this: +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs Browse for the place where the shapefile is going to be and give the shapefile a name(like origna_reprojected). If it prompts you to add the projected layer to the TOC, accept. There, you have your re-projected map with latitude and longitude pair of coordinates. #5 Now, this is not the actual Spherical/Web Mercator projection, but dont worry, this is where you have to stop. All the other custom web-mapping portals will pick this projection and transform it into EPGS::3785 or EPSG:900913 but the coordinates will still remain as the LatLon pair of the projected shapefile. If you want to test, a particular know point, Q-GIS has a lot of room for that. Go ahead and test it.

  • Silverlight Cream for March 06, 2011 -- #1054

    - by Dave Campbell
    In this Back from the Summit Issue, I am overloaded with posts to choose from. Submittals go first, but I'll eventually catch up... hopefully by MIX :) : Ollie Riches(-2-), Colin Eberhardt, John Papa, Jeremy Likness, Martin Krüger, Joost van Schaik, Karl Shifflett, Michael Crump, Georgi Stoyanov, Yochay Kiriaty, Page Brooks, and Deborah Kurata. Above the Fold: Silverlight: "ClassifiedCabinet: A Quick Start" Georgi Stoyanov WP7: "Easy access to WMAppManifest.xml App properties like version and title" Joost van Schaik Multiple: "Flashcards.Show Version 2 for the Desktop, Browser, and Windows Phone" Yochay Kiriaty Shoutouts: Mohamed Mosallem delivered an online session at the Second Riyadh Online Community Summit: Silverlight 4.0 with SharePoint 2010 John-Daniel Trask posted about a release of a new set of tools released for WP7 development... there's a free trial, so definitely worth a look: Mindscape Phone Elements released! From SilverlightCream.com: WP7Contrib: Trickling data to a bound collection Ollie Riches submitted a couple links... first up is this on a way they found to decrease the load on a data template in WP7 to get under the 90 mb limit and then added their solution to the WP7Contrib lib.

  • Having Fun with Coding4Fun&rsquo;s Windows Phone 7 Controls

    - by mbcrump
    I’m a big believer in having a hobby project as you can probably tell from the first sentence in my “personal webpage using Silverlight” article. One of my current hobby projects is to re-do my current WP7 application in the marketplace. I knew up front that I needed a “Loading” animation and a better “About” box. After starting to develop my own, I noticed a great set of WP7 controls by Coding4Fun and decided to use them in my new application. Before I go any further they are FREE and Open-Source. It is really simple to get started, just go to the CodePlex site and click the download button. After you have downloaded it then extract it to a Folder and you will have 4 DLL files. They are listed below: Now create a Windows Phone 7 Project and add references to the DLL’s by right clicking on the References folder and clicking “Add references”.   After adding the references, we can get started. I needed a ProgressOverlay animation or “Loading Screen” while my RSS feed is downloading. Basically, you just need to add the following namespace to whatever page you want the control on: xmlns:Controls="clr-namespace:Coding4Fun.Phone.Controls;assembly=Coding4Fun.Phone.Controls" And then the code inside your Grid or wherever you want the Loading screen placed. <Controls:ProgressOverlay Name="progressOverlay" > <Controls:ProgressOverlay.Content> <TextBlock>Loading</TextBlock> </Controls:ProgressOverlay.Content> </Controls:ProgressOverlay> Bam, you now have a great looking loading screen. Of course inside the ProgressOverlay, you may want to add a Visibility property to turn it off after your data loads if you are using MVVM or similar pattern.   Next up, I needed a nice clean “About Box” that looks good but is also functional. Meaning, if they click on my twitter name, web or email to launch the appropriate task. Again, this is only a few lines of code: var p = new AboutPrompt(); p.VersionNumber = "2.0"; p.Show("Michael Crump", "@mbcrump", "[email protected]", @"http://michaelcrump.net"); A nice clean “About” box with just a few lines of code! I’m all for code that I don’t have to write. It also comes with a pretty sweet InputPrompt for grabbing info from a user: The code for this is also very simple: InputPrompt input = new InputPrompt(); input.Completed += (s, e) => { MessageBox.Show(e.Result.ToString()); }; input.Title = "Input Box"; input.Message = "What does a \"Developer Large\" T-Shirt Mean? "; input.Show(); I also enjoyed the PhoneHelper that allows you to get data out of the WMAppManifest File very easy. So for example if I wanted the Version info from the WMAppManifest file. I could write one line and get it. PhoneHelper.GetAppAttribute("Version") Of course you would want to make sure you add the following using statement: using Coding4Fun.Phone.Controls.Data; You can’t have all these cool controls without a great set of Converters. The included BooleanToVisibility converter will convert a Boolean to and from a Visibility value. This is excellent when using something like a CheckBox to display a TextBox when its checked. See the example below: The code is below: <phone:PhoneApplicationPage.Resources> <Converters:BooleanToVisibilityConverter x:Key="BooleanToVisibilityConverter"/> </phone:PhoneApplicationPage.Resources> <CheckBox x:Name="checkBox"/> <TextBlock Text="Display Text" Visibility="{Binding ElementName=checkBox, Path=IsChecked, Converter={StaticResource BooleanToVisibilityConverter} }"/> That’s not all the goodies included. They also provide a RoundedButton, TimePicker and several other converters. The documentation is great and I would recommend you give them a shot if you need any of this functionality. Btw, thank Brian Peek for his awesome work on Coding4Fun!  Subscribe to my feed

  • New January 2013 Release of the Ajax Control Toolkit

    - by Stephen.Walther
    I am super excited to announce the January 2013 release of the Ajax Control Toolkit! I have one word to describe this release and that word is “Charts” – we’ve added lots of great new chart controls to the Ajax Control Toolkit. You can download the new release directly from http://AjaxControlToolkit.CodePlex.com – or, just fire the following command from the Visual Studio Library Package Manager Console Window (NuGet): Install-Package AjaxControlToolkit You also can view the new chart controls by visiting the “live” Ajax Control Toolkit Sample Site. 5 New Ajax Control Toolkit Chart Controls The Ajax Control Toolkit contains five new chart controls: the AreaChart, BarChart, BubbleChart, LineChart, and PieChart controls. Here is a sample of each of the controls: AreaChart: BarChart: BubbleChart: LineChart: PieChart: We realize that people love to customize the appearance of their charts so all of the chart controls include properties such as color properties. The chart controls render the chart on the browser using SVG. The chart controls are compatible with any browser which supports SVG including Internet Explorer 9 and new and recent versions of Google Chrome, Mozilla Firefox, and Apple Safari. (If you attempt to display a chart on a browser which does not support SVG then you won’t get an error – you just won’t get anything). Updates to the HTML Sanitizer If you are using the HtmlEditorExtender on a public-facing website then it is really important that you enable the HTML Sanitizer to prevent Cross-Site Scripting (XSS) attacks. The HtmlEditorExtender uses the HTML Sanitizer by default. The HTML Sanitizer strips out any suspicious content (like JavaScript code and CSS expressions) from the HTML submitted with the HtmlEditorExtender. We followed the recommendations of OWASP and ha.ckers.org to identify suspicious content. We updated the HTML Sanitizer with this release to protect against new types of XSS attacks. The HTML Sanitizer now has over 220 unit tests. The Ajax Control Toolkit team would like to thank Gil Cohen who helped us identify and block additional XSS attacks. Change in Ajax Control Toolkit Version Format We ran out of numbers. The Ajax Control Toolkit was first released way back in 2006. In previous releases, the version of the Ajax Control Toolkit followed the format: Release Year + Date. So, the previous release was 60919 where 6 represented the 6th release year and 0919 represent September 19. Unfortunately, the AssembyVersion attribute uses a UInt16 data type which has a maximum size of 65,534. The number 70123 is bigger than 65,534 so we had to change our version format with this release. Fortunately, the AssemblyVersion attribute actually accepts four UInt16 numbers so we used another one. This release of the Ajax Control Toolkit is officially version 7.0123. This new version format should work for another 65,000 years. And yes, I realize that 7.0123 is less than 60,919, but we ran out of numbers. Summary I hope that you find the chart controls included with this latest release of the Ajax Control Toolkit useful. Let me know if you use them in applications that you build. And, let me know if you run into any issues using the new chart controls. Next month, back to improving the File Upload control – more exciting stuff.

  • RTL (Arabic and Hebrew) Support for Windows Phone 7

    - by Daniel Moth
    Problem and Background Currently there is no support for Right-To-Left rendering in Windows Phone 7, when developing with Silverlight (itself built on .NET Compact Framework). When I encountered that limitation, I had a flashback to 2005 when I complained about the luck of RTL on NETCF. Unfortunately, the partial solution I proposed back then requires PInvoke and there is no such support on Windows Phone today. Fortunately, my RTL requirements this time were more modest: all I wanted to do was display correctly a translation (of Hebrew or Arabic) in my FREE WP7 translator app. For v1.0 of the app, the code received a string from the service and just put it up on the screen as the translated text. In Arabic and Hebrew, that string (incorrectly) appeared reversed. I knew that, but decided that since it is a platform limitation, I could live with it and so could the users. Yuval P, a colleague at Microsoft, pushed me to offer support for Hebrew (something that I wasn't motivated to pursue if I am honest). After many back and forths, we landed on some code that works. It is certainly not the most efficient code (quite the opposite), but it works and met the bar of minimum effort for v1.1. Thanks Yuval for insisting and contributing most of the code! After Hebrew support was there, I thought the same solution would work for Arabic. Apparently, reversing the Arabic text is not enough: Arabic characters render themselves differently dependent on what preceded/succeeds them(!). So I needed some kind of utility that takes a reversed Arabic string and returns the same string but with the relevant characters "fixed". Luckily, another MS colleague has put out such a library (thanks Bashar): http://arabic4wp7.codeplex.com/. RTL Solution So you have a reversed RTL string and want to make it "right" before displaying on the screen. This is what worked for me (ymmv). Need to split the string into "lines". Not doing this and just reversing the string and sticking it a wrapping text control means that the user not only has to read right to left, they also have to read bottom up. The previous step must take into account a line length that works for both portrait and landscape modes, and of course, not break words in the middle, i.e. find natural breaks. For each line, break it up into words and reverse the order of the words and the order of the letters within each word On the previous step, do not reverse words that should be preserved, e.g. Windows and other such English words that are mixed in with the Arabic or Hebrew words. The same exclusion from reversal applies to numbers. Specifically, for Arabic, once there is a word that is reversed also change its characters. For some code paths, the above has to take into account whether the translation is "from" an RTL language or if it is "to" an RTL language. I packaged the solution in a single code file containing a static class (see the 'Background" section above for… background and credits). Download RTL.cs for your Windows Phone app (to see its usage in action download for FREE "The best translator app") Enjoy, and if you decide to improve on the code, feel free to share back with me… Comments about this post welcome at the original blog.

  • IIS Logfile Visualization with XNA

    - by BobPalmer
    In my office, I have a wall mounted monitor who's whole purpose in life is to display perfmon stats from our various servers.  And on a fairly regular basis, I have folks walk by asking what the lines mean.    After providing the requisite explaination about CPU utilization, disk I/O bottlenecks, etc. this is usually followed by some blank stares from the user in question, and a distillation of all of our engineering wizardry down to the phrase 'So when the red line goes up that's bad then?'   This of course would not do.  So I talked to my friends and our network admin about an option to show something more eye catching and visual, with which we could catch at a glance a feel for what was up with our site.    He initially pointed me out to a video showing GLTail and Chipmunk done in Ruby.  Realizing this was both awesome, and that I needed an excuse to do something in XNA, I decided to knock out a proof of concept for something very similar, but with a few tweaks.   Here's a link to a video of the current prototype:   http://www.youtube.com/watch?v=jM_PWZbtH2I   Essentially this app opens up a log file (even an active one) and begins pulling out the lines of text.  (Here's a good Code Project link that covers how to do tail reading from an active text file: http://www.codeproject.com/KB/files/tail.aspx).   As new data is added, a bubble is generated in the application - a GET statement comes from the left, and a POST from the right.  I then run it through a series of expression checkers, and based on the kind of statement and the pattern, a bubble of an appropriate color is generated.   For example, if I get a 500, a huge red bubble pops out.  Others are based on the part of the system the page is from - i.e. green bubbles are from our claims management subsystem, and blue bubbles are from the pages our scheduling staff use to schedule patients.  Others include the purple bubbles for security and login, and yellow bubbles for some miscellaneous pages.   The little grey bubbles represent things like images, JS, CSS, etc - and their small size makes them work like grease to keep the larger page bubbles moving.   The app is also smart enough that if it is starting to bog down with handling the physics and interactions, it will suspend new bubbles until enough have dropped off that performance can resume (you can see this slight stuttering in the sample video).   The net result is that anyone will be able to look up on the wall monitor, and instantly get a quick feel for how things are going on the floor.  Website slow?  You can get a feel for both volume and utilized modules with one glance.  Website crashing?  Look for a wall of giant red bubbles.  No activity at all?  Maybe the site is down.  Now couple this with utilization within a farm, and cross referenced with a second app showing the same kind of data from your SQL database...   As for the app itself, it's a windows XNA project with the code in C#.   The physics are handled by the Farseer physicis eingine for XNA (http://www.codeplex.com/FarseerPhysics) which is just pure goodness.  The samples are great, and I had the app up and working in two evenings (half of that was fine tuning, and the other was me coding with a kid in my lap).   My next steps include wiring this to SQL (I have some ideas...), and adding a nice configuration module.  For example, you could use polygons, etc to tie to your regex - or more entertaining things like having a little human ragdoll to represent a user login.     Once that's wrapped up and I have a chance to complete some hardening, I will be releasing the whole thing into the wild as opensource.     Feel free to ping me if you have any questions! -Bob

Employee Info Starter Kit is highly influenced by the concept ‘Pareto Principle’ or 80-20 rule. where it is targeted to enable a web developer to gain 80% productivity with 20% of effort with respect to learning curve and production. User Stories The user end functionalities of this starter kit are pretty simple and straight forward that are focused in to perform CRUD operation on employee records as described below. Creating a new employee record Read existing employee record Update an existing employee record Delete existing employee records Key Technology Areas ASP.NET 4.0 Entity Framework 4.0 T-4 Template Visual Studio 2010 Architectural Objective There is no universal architecture which can be considered as the best for all sorts of applications around the world. Based on requirements, constraints, environment, application architecture can differ from one to another. Trade-off factors are one of the important considerations while deciding a particular architectural solution. Employee Info Starter Kit is highly influenced by the concept ‘Pareto Principle’ or 80-20 rule, where it is targeted to enable a web developer to gain 80% productivity with 20% of effort with respect to learning curve and production. “Productivity” as the architectural objective typically also includes other trade-off factors as well as, such as testability, flexibility, performance etc. Fortunately Microsoft .NET Framework 4.0 and Visual Studio 2010 includes lots of great features that have been implemented cleverly in this project to reduce these trade-off factors in the minimum level. Why Employee Info Starter Kit is Not a Framework? Application frameworks are really great for productivity, some of which are really unavoidable in this modern age. However relying too many frameworks may overkill a project, as frameworks are typically designed to serve wide range of different usage and are less customizable or editable. On the other hand having implementation patterns can be useful for developers, as it enables them to adjust application on demand. Employee Info Starter Kit provides hundreds of “connected” snippets and implementation patterns to demonstrate problem solutions in actual production environment. It also includes Visual Studio T-4 templates that generate thousands lines of data access and business logic layer repetitive codes in literally few seconds on the fly, which are fully mock testable due to language support for partial methods and latest support for mock testing in Entity Framework. Why Employee Info Starter Kit is Different than Other Open-source Web Applications? Software development is one of the rapid growing industries around the globe, where the technology is being updated very frequently to adapt greater challenges over time. There are literally thousands of community web sites, blogs and forums that are dedicated to provide support to adapt new technologies. While some are really great to enable learning new technologies quickly, in most cases they are either too “simple and brief” to be used in real world scenarios or too “complex and detailed” which are typically focused to achieve a product goal (such as CMS, e-Commerce etc) from "end user" perspective and have a long duration learning curve with respect to the corresponding technology. Employee Info Starter Kit, as a web project, is basically "developer" oriented which actually considers a hybrid approach as “simple and detailed”, where a simple domain has been considered to intentionally illustrate most of the architectural and implementation challenges faced by web application developers so that anyone can dive into deep into the corresponding new technology or concept quickly. Roadmap Since its first release by 2008 in MSDN Code Gallery, Employee Info Starter Kit gained a huge popularity in ASP.NET community and had 1, 50,000+ downloads afterwards. Being encouraged with this great response, we have a strong commitment for the community to provide support for it with respect to latest technologies continuously. Currently hosted in Codeplex, this community driven project is planned to have a wide range of individual editions, each of which will be focused on a selected application architecture, framework or platform, such as ASP.NET Webform, ASP.NET Dynamic Data, ASP.NET MVC, jQuery Ajax (RIA), Silverlight (RIA), Azure Service Platform (Cloud), Visual Studio Automated Test etc. See here for full list of current and future editions.

    In this Issue: Michael Washington, Jesse Liberty, Deborah Kurata(-2-, -3-, -4-), Sergey Barskiy(-2-), Miroslav Nedyalkov, Jeff Prosise, and Matthias Shapiro(-2-). Above the Fold: Silverlight: "Building a Multi-Page Silverlight LOB Application" Deborah Kurata WP7: "Windows Phone 7 [Controls] Project" Sergey Barskiy Sketchflow: "Sketchflow To Final" Michael Washington From SilverlightCream.com: Sketchflow To Final Check out this post by Michael Washington detailing the Sketchflow he did of his app, and how the final result tracks amazingly well. Windows Phone From Scratch #19 – MVVM Light Toolkit Soup To Nuts #4 Continuing to try to catch up to Jesse Liberty is this post, number 19 in the Windows Phone series and the 4th in that series about MVVMLight, and discussing binding a collection in the ViewModel to a ListBox in the view. Building a Multi-Page Silverlight LOB Application Deborah Kurata has the first 4 parts up (in 2 days) in a 6-part tutorial series she's doing on building a Silverlight LOB app. The first post was an intro and link to the rest as they become available. This 2nd post is getting the app newed up and making sure you've got your head wrapped around multiple pages. Theming a Silverlight Application using Existing Themes Deborah Kurata's next part is about getting started with themes in your app using the themes provided in the toolkit specifically. Theming a Silverlight Application using Custom Themes Deborah Kurata's next tutorial in the series is also about themes, but this time it's about custom themes... or rather customized from a 'standard' one in this case. Adding a New Page to a Multi-Page Silverlight Application Deborah Kurata's last available post in the tutorial series is this one on adding a new page to the app. Windows Phone 7 Project Sergey Barskiy has a pair of posts up about a calendar control that he is building and has out on CodePlex... nice-looking control too!

  • Improving WIF&rsquo;s Claims-based Authorization - Part 1

    - by Your DisplayName here!
    As mentioned in my last post, I made several additions to WIF’s built-in authorization infrastructure to make it more flexible and easy to use. The foundation for all this work is that you have to be able to directly call the registered ClaimsAuthorizationManager. The following snippet is the universal way to get to the WIF configuration that is currently in effect: public static ServiceConfiguration ServiceConfiguration {     get     {         if (OperationContext.Current == null)         {             // no WCF             return FederatedAuthentication.ServiceConfiguration;         }         // search message property         if (OperationContext.Current.IncomingMessageProperties. ContainsKey("ServiceConfiguration"))         {             var configuration = OperationContext.Current. IncomingMessageProperties["ServiceConfiguration"] as ServiceConfiguration;             if (configuration != null)             {                 return configuration;             }         }         // return configuration from configuration file         return new ServiceConfiguration();     } }   From here you can grab ServiceConfiguration.ClaimsAuthoriationManager which give you direct access to the CheckAccess method (and thus control over claim types and values). I then created the following wrapper methods: public static bool CheckAccess(string resource, string action) {     return CheckAccess(resource, action, Thread.CurrentPrincipal as IClaimsPrincipal); } public static bool CheckAccess(string resource, string action, IClaimsPrincipal principal) {     var context = new AuthorizationContext(principal, resource, action);     return AuthorizationManager.CheckAccess(context); } public static bool CheckAccess(Collection<Claim> actions, Collection<Claim> resources) {     return CheckAccess(new AuthorizationContext(         Thread.CurrentPrincipal.AsClaimsPrincipal(), resources, actions)); } public static bool CheckAccess(AuthorizationContext context) {     return AuthorizationManager.CheckAccess(context); } I also created the same set of methods but called DemandAccess. They internally use CheckAccess and will throw a SecurityException when false is returned. All the code is part of Thinktecture.IdentityModel on Codeplex – or via NuGet (Install-Package Thinktecture.IdentityModel).
