• Hello From South Florida

  - by Sam Abraham

  Fellow Blog Readers: I figured I use my first blog post on GeeksWithBlogs to introduce myself.   I recently relocated from Long Island, NY to South Florida where I joined a local company as Software Engineer specializing in technologies such as C#, ASP.Net 3.5, WCF, Silverlight, SQL Server 2008 and LINQ, to name a few. I am an MCP and MCTS ASP.Net 3.5, looking to get my .Net 4.0 certification soon.   Having been in industry for a few years so far, I figured I would share with you my take on the importance of being involved(at least attending) in local user groups.   I am a firm believer that besides using a certain technology, the best way to expand one’s knowledge is by sharing it with others and being equally open to learn from others just as much as you are willing to share what you know.   In my opinion, an important factor that makes a good developer stand-out is his/her ability to keep abreast with the latest and greatest even in areas outside his/her direct expertise.   Additionally, having spoken to various recruiters, technical user group attendees are always favorably looked upon as genuinely interested in their field and willing to take the initiative to expand their knowledge which offers job candidates good leverage when competing for jobs.   I believe I am very blessed to be in an area with a very strong and vibrant developer community. I found in the local .Net community leadership a genuine interest in constantly extending the opportunity to all developers to get more involved and encouraging those who are willing to take that initiative achieve their goal: Speak in meetings, volunteer at events or write and publish articles/blogs about latest and greatest technologies.   With Vishal Shukla (Site director for the West Palm Beach .Net User Group) traveling overseas, I have been extended the opportunity to come on board as site coordinator for FladotNet's WPB .Net User Group along with Venkata Subramanian, an opportunity which I gratefully accepted.   Being involved in running a .Net User Group will surely help me personally and professionally, but my real hope is to use this opportunity to assist in delivering the ultimate common-goal: spread the word about new .Net Technologies, help everybody get more involved and simply have fun learning new things.   With my introduction out of the way, in the next few days I will be posting some notes on an upcoming talk I will be giving about MVC2 and VS2010 in mid-April.   Environment.Exit(0); --Sam

• Connect to QuickBooks from PowerBuilder using RSSBus ADO.NET Data Provider

  - by dataintegration

  The RSSBus ADO.NET providers are easy-to-use, standards based controls that can be used from any platform or development technology that supports Microsoft .NET, including Sybase PowerBuilder. In this article we show how to use the RSSBus ADO.NET Provider for QuickBooks in PowerBuilder. A similar approach can be used from PowerBuilder with other RSSBus ADO.NET Data Providers to access data from Salesforce, SharePoint, Dynamics CRM, Google, OData, etc. In this article we will show how to create a basic PowerBuilder application that performs CRUD operations using the RSSBus ADO.NET Provider for QuickBooks. Step 1: Open PowerBuilder and create a new WPF Window Application solution. Step 2: Add all the Visual Controls needed for the connection properties. Step 3: Add the DataGrid control from the .NET controls. Step 4:Configure the columns of the DataGrid control as shown below. The column bindings will depend on the table. <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=ID}" Header="ID" Width="SizeToHeader" /> <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Name}" Header="Name" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid> Step 5:Add a reference to the RSSBus ADO.NET Provider for QuickBooks assembly. Step 6:Optional: Set the QBXML Version to 6. Some of the tables in QuickBooks require a later version of QuickBooks to support updates and deletes. Please check the help for details. Connect the DataGrid: Once the visual elements have been configured, developers can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of a SQL query: System.Data.RSSBus.QuickBooks.QuickBooksConnection conn conn = create System.Data.RSSBus.QuickBooks.QuickBooksConnection(connectionString) System.Data.RSSBus.QuickBooks.QuickBooksCommand comm comm = create System.Data.RSSBus.QuickBooks.QuickBooksCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.RSSBus.QuickBooks.QuickBooksDataAdapter dataAdapter dataAdapter = create System.Data.RSSBus.QuickBooks.QuickBooksDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView The code above can be used to bind data from any query (set this in command), to the DataGrid. The DataGrid should have the same columns as those returned from the SELECT statement. PowerBuilder Sample Project The included sample project includes the steps outlined in this article. You will also need the QuickBooks ADO.NET Data Provider to make the connection. You can download a free trial here.

• After 10 Years, MySQL Still the Right Choice for ScienceLogic's "Best Network Monitoring System on the Planet"

  - by Rebecca Hansen

  ScienceLogic has a pretty fantastic network monitoring appliance.  So good in fact that InfoWorld gave it their "2013 Best Network Monitoring System on the Planet" award.  Inside their "ultraflexible, ultrascalable, carrier-grade" enterprise appliance, ScienceLogic relies on MySQL and has since their start in 2003.  Check out some of the things they've been able to do with MySQL and their reasons for continuing to use MySQL in these highlights from our new MySQL ScienceLogic case study. Science Logic's larger customers use their appliance to monitor and manage  20,000+ devices, each of which generates a steady stream of data and a workload that is 85% write. On a large system, the MySQL database: Averages 8,000 queries every second or about 1 billion queries a day Can reach 175,000 tables and up to 20 million rows in a single table Is 2 terabytes on average and up to 6 terabytes "We told our customers they could add more and more devices. With MySQL, we haven't had any problems. When our customers have problems, we get calls. Not getting calls is a huge benefit." Matt Luebke, ScienceLogic Chief Software Architect.? ScienceLogic was approached by a number of Big Data / NoSQL vendors, but decided against using a NoSQL-only solution. Said Matt, "There are times when you really need SQL. NoSQL can't show me the top 10 users of CPU, or show me the bottom ten consumer of hard disk. That's why we weren't interested in changing and why we are very interested in MySQL 5.6. It's great that it can do relational and key-value using memcached." The ScienceLogic team is very cautious about putting only very stable technology into their product, and according to Matt, MySQL has been very stable: "We've been using MySQL for 10 years and we have never had any reliability problems. Ever." ScienceLogic now uses SSDs for their write-intensive appliance and that change alone has helped them achieve a 5x performance increase.

• Why does aptitude want to remove a bunch of files?

  - by Mediterran81

  Recently I encountered dependencies resolve issues when using APTITUDE (it is my favorite). Nevertheless, I started to feel that APTITUDE does not behave as it is supposed to be in 64 bits systems while apt-get works fine. Can someone confirm that APTITUDE is buggy in Ubuntu 11.10 amd64? Edit: For example, when tried to install ntfs-config using APTITUDE, it asked me to remove over 100 packages (skype for example), while using apt-get worked fine. han@L502X:~$ sudo aptitude install ntfs-config [sudo] password for han: The following NEW packages will be installed: ntfs-3g{ab} ntfs-config 0 packages upgraded, 2 newly installed, 0 to remove and 0 not upgraded. Need to get 0 B/640 kB of archives. After unpacking 2,466 kB will be used. The following packages have unmet dependencies: ntfs-3g: Conflicts: ntfsprogs but 2.0.0-1ubuntu4 is installed.

• 302: this blog will be closed

  - by preishuber

  After nearly 7 years I will discontinue blogging on this site. My resources are limited. You can reach my German blog which is used to support my customers. Looking back to a long an interesting journey ASP.NET by ScottGu That was the reason to attend this site and support Microsoft as much as I can. For that I was honored as ASP.NET MVP- thanks again. Meet Scoot several times. Great guy! Forums I have left NNTP forums a few years ago and now Microsoft closed it- It was my idea ;-) AJAX Was the wrong way- JQuery won the game IIS7 That is really a great plattform and the IIS team rules. I am sad that is so silent around that topic. ASP.NET after 2.0 Is no longer my world. I love ASP.NET and ASP.NET Server controls. I hate the discussion about how to follow the holy rules of MVC. Microsoft have dropped the goal to bring ASP.NET to #1 and accepted PHP is it. Facebook & Twittering Microblogging takes over a part of the blogging business. Shorter faster cheaper- or as SteveB mentioned - do more with less. Google Google is taking over the web. I am using Bing every time as I can but Google have more options. Sorry Microsoft you will loose that game. Apple That is not the biggest problem of Microsoft. the Ixxx takes over a small part but big money of the market, but the customers are not strongly linked. New wave new hype- Game over Apple. Silverlight My new home. I can reuse a lot of my skills and love the possibilitys. Silverligth will passing WPF-and strike Flash Windows phone 7 Also my skills fit. I just will use it for fun. I am not really satisfied about what I have heard from MIX. Guys from Redmond, I am sad to say you have been the best Smartphone OS and lost everything. The ADO vNext Story That will be the next mystic point. WCF, REST, JSON, ATOM and now OData. Nothing about SQL commands. LINQ, ORM is also not the final solution for multilayered disconnected async scenarios. Personally I prefere the OData idea and dislike the Swiss Army Knife (German Eierlegende Wollmilchsau) WCF. I am still in INETA Speakers board and I am glad to come to your user group. In all other cases you can hire me over ppedv AG. Good by and have good live.

• Launch 2010 Technical Readiness Unofficial Q&amp;A.

  - by mbcrump

  I had an email from one of my readers about the 2010 Technical Readiness Series. Please read below: Hi Michael, I noticed you blogged a while back that you were going to attend MS 2010 Launch event. I’m going to the session in Seattle on May 27, is it worth it to attend? Also, I’m wondering if they give any free software away like VS2010 Pro? Any decent vendors? Looking forward to hearing back from you. I decided this information would probably benefit several instead of just responding back to the reader. In case you are not aware, MS has a 2010 launch event showing VS2010, Office 2010, SharePoint 2010 and SQL Server 2008R2.  You can sign up for an event here: https://microsoft.crgevents.com/Register2010/Content/Event_Selection.aspx I’ve answered the questions asked below. Q: Is it worth going? A: It is if you have had little or no exposure to the latest 2010 products. Most people are familiar with VS2010, but have not seen SharePoint 2010 Office 2010 or Windows Phone 7. It is designed to get you up to speed very quickly. If you have watched most of the MIX videos and keep up with .NET in general, you will benefit more by having the ability to ask questions.    Q: Did you get any free software? A: No, only demos including: VS2010/Office 2010 – They give you a link to the url where you can download the trial version. Windows 7 Enterprise – You get a DVD with the trial version loaded. Q: Do they give away any cool swag? A: Just a Microsoft T-Shirt (XL). Q: What about the vendor selection? A: At the event that I went to, most vendors were pushing SharePoint products. There wasn’t a lot of variety in the selection. Most vendors were giving away the typical pens, buttons and stickers and trial software. If you have any other questions, feel free to contact me. I will answer and add to this un-official FAQ.

• What do you think of the EntLib 5.0 configuration tool?

  Hello again! Its been a while, I know. Ive been busy over the last few months with several projects, some of them software related, and one of them human my son Jesse was born on 26 February 2010. Fun times! Meanwhile, back in Redmond, the p&p team has been busy working on Enterprise Library 5.0 see Grigoris announcement for details on the beta. Theres a ton of new stuff in this release, but theres one big new feature that hasnt received a lot of attention that Im keen to hear your perspectives on. The change is the biggest overhaul to the configuration tool since Enterprise Library was launched. If you havent yet grabbed the EntLib 5.0 beta, heres a before and after shot of the config tool: Enterprise Library 4.1 config tool Enterprise Library 5.0 (beta 1) config tool The tool has been rebuilt from the ground up in response to some feedback and usability studies from the previous version of the tool. But is this a step in the right direction? Id love to hear what you think. If youve downloaded EntLib 5.0 and tried out the tool, please share your thoughts on: First impressions. Is the tool easy to understand? Easy to find what youre looking for? Easy to read existing configuration? Pretty? Ease of use for real life tasks. Rather than make up your own tasks, here are a few sample scenarios you might want to try: Configure the data access block with a SQL Server connection called Audit that points to a database called Audit on a server called DB Configure the logging block so that any log entries in the Audit category are written to both the Event Log and the Audit database (see above) Configure the validation block with a ruleset called Email Address that uses an appropriate regular expression for e-mail addresses Configure the policy injection block such that any calls to classes in the MyCompany.Security namespace are logged before and after the call using the Audit category (see above) Comparison with the old config tool. What do you like better in the new tool? What did you like better in the old tool? How do you rate your level of expertise using the old tool? Keep in mind that I no longer work in the p&p team, so I cant say how any of this feedback will be used (although Im sure the team is listening!). However since Ive invested so much time in Enterprise Library, both in leading the team and using the product on real projects Im very interested to hear what you all think of the tools new direction.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• WPF: Reloading app parts to handle persistence as well as memory management.

  - by Ingó Vals

  I created a app using Microsoft's WPF. It mostly handles data reading and input as well as associating relations between data within specific parameters. As a total beginner I made some bad design decision ( not so much decisions as using the first thing I got to work ) but now understanding WPF better I'm getting the urge to refactor my code with better design principles. I had several problems but I guess each deserves it's own question for clarity. Here I'm asking for proper ways to handle the data itself. In the original I wrapped each row in a object when fetched from database ( using LINQ to SQL ) somewhat like Active Record just not active or persistence (each app instance had it's own data handling part). The app has subunits handling different aspects. However as it was setup it loaded everything when started. This creates several problems, for example often it wouldn't be neccesary to load a part unless we were specifically going to work with that part so I wan't some form of lazy loading. Also there was problem with inner persistance because you might create a new object/row in one aspect and perhaps set relation between it and different object but the new object wouldn't appear until the program was restarted. Persistance between instances of the app won't be huge problem because of the small amount of people using the program. While I could solve this now using dirty tricks I would rather refactor the program and do it elegantly, Now the question is how. I know there are several ways and a few come to mind: 1) Each aspect of the program is it's own UserControl that get's reloaded/instanced everytime you navigate to it. This ensures you only load up the data you need and you get some persistancy. DB server located on same LAN and tables are small so that shouldn't be a big problem. Minor drawback is that you would have to remember the state of each aspect so you wouldn't always start at beginners square. 2) Having a ViewModel type object at the base level of the app with lazy loading and some kind of timeout. I would then propegate this object down the visual tree to ensure every aspect is getting it's data from the same instance 3) Semi active record data layer with static load methods. 4) Some other idea What in your opinion is the most practical way in WPF, what does MVVM assume?

• Why I Love Microsoft Development

  - by Brian Lanham

  I've been writing software for a while and recently had an opportunity to broaden my horizons and start developing for iOS. We decided to leverage, as much as possible, our existing skills and use MonoTouch and MonoDevelop by Novell.    For those of you who do not know, Mono is a .NET port originally designed for Linux but adapted for other platforms as well. MonoTouch is a port specifically for building iOS applications using the .NET framework. MonoDroid is a port (in CTP-esque release) for Android.   A MISSING COMPONENT - VISUAL DESIGNER   MonoDevelop lacks one very significant component compared with other tools I am using: NO VISUAL DESIGNER. Instead of using an integrated visual designer, MonoDevelop shells to the Mac OS "Interface Builder".  Since MonoDevelop lets me have a "Visual Studio-esque" feel *and* I get to use C#, AND it's FREE, I am gladly willing to overlook this.  In fact, it's not even a question.  Free?  Sure, I'll take it with no Visual Designer.   In my experiences I've grown from UNIX and DOS to .NET development through many steps. Java/JSP/Servlets; Windows; Web; etc. I've been doing .NET for quite a few years and I guess I just got "comfortable" with the tools.   WHY AM I NOT GETTING IT?   Interface Builder (IB) is amazingly confusing for me. I had the opportunity to speak at the Northern VA Code Camp on 12/11/2010. My presentation was "Getting Started with iOS Development using MonoTouch and C#".    At the visual design part of the presentation, I asked one of the 3 or 4 Mac developers in the room about my confusion with the IB. I don't understand why the "Classes" list includes objects. I don't understand what "File's Owner" is. And, most importantly, WHAT THE HECK IS AN OUTLET AND WHY IS IT NECESSARY?!?!?"   His response to these question (especially Outlets): "They did it wrong."   I'm accustom to a visual designer that creates variables for graphical widgets for me. Not IB. Instead, I have to create "Outlets" manually. I still do not understand why and, the explanation from a seasoned Mac developer is that it's wrong. (He received nods of confirmation from the other Mac devs in the room.)   I LOVE MS DEV   I love development for Microsoft platforms using Microsoft development tools. I love Windows 7. I love Visual Studio 2010. I love SQL Server. Azure, Entity Framework, Active Directory, Office, WCF/WF/WPF, etc. are all designed with integration in mind. They are also all designed with developers in mind.   Steve Ballmer recently ranted "It's the developers!" That's why it is relatively quick to build apps using MS tools. Clearly, MS knows that while we usually enjoy building technology solutions, we are here to make money. And we need tools that accelerate our time to market without compromising the power and quality of our solutions.   So, yeah, I am sucking up I guess. But I love Microsoft Development. Thank you, Microsoft, for providing the plethora of great development tools.    P.S. (but please slow down a bit…I'm having trouble keeping up!)

• Content Based Routing with BRE and ESB

  - by Christopher House

  I've been working with BizTalk 2009 and the ESB toolkit for the past couple of days.  This is actually my first exposure to ESB and so far I'm pleased with how easy it is to work with. Initially we had planned to use UDDI for storing endpoint information.  However after discussing this with my client, we opted to look at BRE instead of UDDI since we're already storing transforms in BRE.  Fortunately making the change to BRE from UDDI was quite simple.  This solution of course has the added advantage of not needing to go through the convoluted process of registering our endpoints in UDDI. The first thing to remember if you want to do content based routing with BRE and ESB is that the pipleines included in the ESB toolkit don't include disassembler components.  This means that you'll need to first create a custom recieve pipeline with the necessary disassembler for your message type as well as the ESB components, itinerary selector and dispather. Next you need to create a BRE policy.  The ESB.ContextInfo vocabulary contains vocabulary links for the various items in the ESB context dictionary.  In this vocabulary, you'll find an item called Context Message Type, use this as the left hand side of your condition.  Set the right hand side to your message type, something like http://your.message.namespace/#yourrootelement.  Now find the ESB.EndPointInfo vocabulary.  This contains links to all the properties related to endpoint information.  Use the various set operators in your rule's action to configure your endpoint. In the example above, I'm using the WCF-SQL adapter. Now that the hard work is out of the way, you just need to configure the resolver in your itinerary. Nothing complicated here.  Just select BRE as your resolver implementation and select your policy from the drop-down list.  Note that when you select a policy, the Version field will be automatically filled in with the version of your policy.  If you leave this as-is, the resolver will always use that policy version.  Alternatively, you can clear the version number and the resolver will use the highest deployed version.

• Backup Azure Tables with the Enzo Backup API

  - by Herve Roggero

  In case you missed it, you can now backup (and restore) Azure Tables and SQL Databases using an API directly. The features available through the API can be found here: http://www.bluesyntax.net/backup20api.aspx and the online help for the API is here: http://www.bluesyntax.net/EnzoCloudBackup20/APIIntro.aspx. Backing up Azure Tables can’t be any easier than with the Enzo Backup API. Here is a sample code that does the trick: // Create the backup helper class. The constructor automatically sets the SourceStorageAccount property StorageBackupHelper backup = new StorageBackupHelper("storageaccountname", "storageaccountkey", "sourceStorageaccountname", "sourceStorageaccountkey", true, "apilicensekey"); // Now set some properties… backup.UseCloudAgent = false;                                       // backup locally backup.DeviceURI = @"c:\TMP\azuretablebackup.bkp";    // to this file backup.Override = true; backup.Location = DeviceLocation.LocalFile; // Set optional performance options backup.PKTableStrategy.Mode = BSC.Backup.API.TableStrategyMode.GUID; // Set GUID strategy by default backup.MaxRESTPerSec = 200; // Attempt to stay below 200 REST calls per second // Start the backup now… string taskId = backup.Backup(); // Use the Environment class to get the final status of the operation EnvironmentHelper env = new EnvironmentHelper("storageaccountname", "storageaccountkey", "apilicensekey"); string status = env.GetOperationStatus(taskId);   As you can see above, the code is straightforward. You provide connection settings in the constructor, set a few options indicating where the backup device will be located, set optional performance parameters and start the backup. The performance options are designed to help you backup your Azure Tables quickly, while attempting to keep under a specific threshold to prevent Storage Account throttling. For example, the MaxRESTPerSec property will attempt to keep the overall backup operation under 200 rest calls per second. Another performance option if the Backup Strategy for Azure Tables. By default, all tables are simply scanned. While this works best for smaller Azure Tables, larger tables can use the GUID strategy, which will issue requests against an Azure Table in parallel assuming the PartitionKey stores GUID values. It doesn’t mean that your PartitionKey must have GUIDs however for this strategy to work; but the backup algorithm is tuned for this condition. Other options are available as well, such as filtering which columns, entities or tables are being backed up. Check out more on the Blue Syntax website at http://www.bluesyntax.net.

• 0xC0017011 and other error messages - what is the error message text?

  Recently there was a bug raised against BIDS Helper which originated in my Expression Editor control. Thankfully the person that raised it kindly included a screenshot, so I had the error code (HRESULT 0xC0017011) and a stack trace that pointed the finger firmly at my control, but no error message text. The code itself looked fine so I searched on the error code but got no results. I’d expected to get a hit from Books Online with the Integration Services Error and Message Reference topic at the very least, but no joy. There is however a more accurate and definitive reference, namely the header file that defines all these codes dtsmsg.h which you can find at- C:\Program Files (x86)\Microsoft SQL Server\110\SDK\Include\dtsmsg.h Looking the code up in the header file gave me a much more useful error message. //////////////////////////////////////////////////////////////////////////// // The parameter is sensitive // // MessageId: DTS_E_SENSITIVEPARAMVALUENOTALLOWED // // MessageText: // // Accessing value of the parameter variable for the sensitive parameter "%1!s!" is not allowed. Verify that the variable is used properly and that it protects the sensitive information. // #define DTS_E_SENSITIVEPARAMVALUENOTALLOWED ((HRESULT)0xC0017011L) Unfortunately I’d forgotten all about this. By the time I had remembered about it, the person who raised the issue had managed to narrow it down to something to do with having  sensitive parameter. Putting that together with the error message I’d finally found, a quick poke around in the code and I found the new GetSensitiveValue method which seemed to do the trick. The HResult fields are also listed online but it only shows the short error message, and it doesn’t include that all so important HRESULT value itself. So let this be a lesson to you (and me!), if you need to check  SSIS error go straight to the horses mouth - dtsmsg.h. This is particularly true when working with early builds, or CTP releases when we expect the documentation to be a bit behind. There is also a programmatic approach to getting better SSIS error messages. I should to take another look at the error handling in the control, or the way it is hosted in BIDS Helper. I suspect that if I use an implementation of Microsoft.SqlServer.Dts.Runtime.Wrapper.IDTSInfoEvents100 I could catch the error itself and get the full error message text which I could then report back. This would obviously be a better user experience and also make it easier to diagnose any issues like this in the future. See ExprssionEvaluator.cs for an example of this in use in the Expression Editor control.

• Microsoft Virtual Academy

  Carpe Diem It's been since a while that I could write an article for this blog but alas, I was (and still am) very busy with customer's work. Which is actually good. So, what is this article going to tell you? Well, in general, just what I already tweeted, that life is constant process of learning - especially as software craftsman. Due to an upcoming new customer project in ASP.NET I had to seize the opportunity to get my head deeper into latest available technologies, like Windows Azure and SQL Azure. I know... cloud computing and so on is not a recent development and already available since quite a while but I never any means to get myself into this since roughly two weeks ago. Microsoft Virtual Academy I can't remember exactly what guided me towards the Microsoft Virtual Academy (MVA), oh wait... Yes, it was a posting on Facebook from an old CLIP community friend. He posted a shortened URL with #MVA tag that caught my attention. Thanks for that Thomas Kuberek. After the usual sign in or registration via Live ID I was a little bit surprised that Mauritius is not an available country option... Quick mail exchange with the MVA Decan, and yeah, apologies for the missing entry. So, currently I'm learning about Microsoft products and services, and collecting points under "Not Listed Country" until Mauritius is going to be added. Hopefully soon, as MVA honors your effort with different knowledge ranks that are compared to other students with public profiles. I think it's a nice move to add some game and competition factor into the learning game. The tracks and their different modules are mainly references to publicly available material online, namely on either MSDN, TechNet, Channel9, or other Microsoft based sites. The course material therefore also varies in different media and formats, ranging from simple online articles over downloadable documents (.docx or .pdf) to Silverlight / Windows Media streams with download options. Self-assessment and students ranking Each module in a track can be finished by taking part in a self-assessment. Up to now, the assessment I did (and passed) were limited to 10 minutes available time, and consisted of six to seven questions on the module training material. Nothing too serious but it gives you a glimpse idea how Microsoft certification exams are structured. Conclusion Nothing really new but nicely gathered, assembled and presented to the MVA students. At the moment, I wouldn't dare to compare the richness and quality of those courses with professional training offers, like Pluralsight .NET Training, LearnDevNow, VTC, etc. at all, but I think that MVA has potential. Give it a try, and let me know about your opinions.

• How to join two collections with LINQ

  - by JustinGreenwood

  Here is a simple and complete example of how to perform joins on two collections with LINQ. I wrote it for a friend to show him, in one simple file, the power of LINQ queries and anonymous objects. In the file below, there are two simple data classes defined: Person and Item. In the beginning of the main method, two collections are created. Note that the Item's OwnerId field reference the PersonId of a Person object. The effect of the LINQ query below is equivalent to a SQL statement looking like this: select Person.PersonName as OwnerName, Item.ItemName as OwnedItem from Person inner join Item on Item.OwnerId = Person.PersonId order by Item.ItemName desc; using System; using System.Collections.Generic; using System.Linq; namespace LinqJoinAnonymousObjects { class Program { class Person { public int PersonId { get; set; } public string PersonName { get; set; } } class Item { public string ItemName { get; set; } public int OwnerId { get; set; } } static void Main(string[] args) { // Create two collections: one of people, and another with their possessions. var people = new List<Person> { new Person { PersonId=1, PersonName="Justin" }, new Person { PersonId=2, PersonName="Arthur" }, new Person { PersonId=3, PersonName="Bob" } }; var items = new List<Item> { new Item { OwnerId=1, ItemName="Armor" }, new Item { OwnerId=1, ItemName="Book" }, new Item { OwnerId=2, ItemName="Chain Mail" }, new Item { OwnerId=2, ItemName="Excalibur" }, new Item { OwnerId=3, ItemName="Bubbles" }, new Item { OwnerId=3, ItemName="Gold" } }; // Create a new, anonymous composite result for person id=2. var compositeResult = from p in people join i in items on p.PersonId equals i.OwnerId where p.PersonId == 2 orderby i.ItemName descending select new { OwnerName = p.PersonName, OwnedItem = i.ItemName }; // The query doesn't evaluate until you iterate through the query or convert it to a list Console.WriteLine("[" + compositeResult.GetType().Name + "]"); // Convert to a list and loop through it. var compositeList = compositeResult.ToList(); Console.WriteLine("[" + compositeList.GetType().Name + "]"); foreach (var o in compositeList) { Console.WriteLine("\t[" + o.GetType().Name + "] " + o.OwnerName + " - " + o.OwnedItem); } Console.ReadKey(); } } } The output of the program is below: [WhereSelectEnumerableIterator`2] [List`1] [<>f__AnonymousType1`2] Arthur - Excalibur [<>f__AnonymousType1`2] Arthur - Chain Mail

• Online Application Upgrade

  - by lsarecz

  Amikor HA (High Availability - Magas Rendelkezésre Állás) megoldásokról beszélünk, általában elsoként a klaszterek, redundáns megoldások jutnak eszünkbe. Pedig nem csak a hardver hibákra kell gondolni, hanem a tervezett leállásokkal is érdemes foglalkozni. Az egyik talán legkevésbé megoldott probléma az, ha egy alkalmazás verzió váltást kell végrehajtani úgy, hogy közben változik az adatstruktúra is. Ez nyilván azt eredményezi, hogy le kell állítani az adatbázist is, és az átszervezéseket, akár adat átalakításokkal együtt végre kell hajtani. De a legnagyobb probléma talán az, hogy amennyiben valami rosszul sül el, és vissza kell állni a kiinduló állapotra, akkor az adatbázis mentést is vissza kell tölteni, hiszen átmenetileg minden felhasználó aki épp használatba vette az új alkalmazás verziót már egy új adatstruktúrába kezdett dolgozni. Az Oracle Database Online Application Upgrade képessége, vagy pontosabb nevén az Edition Based Redefinition pontosan ezt a problémát célozza meg. Az Edition Based Redefinition 3 alap objektummal muködik, ezek: edition, editioning view és crossedition trigger. Az edition egy új nonschema objektum típus. 11gR2 verziótól minden adatbázis rendelkezik legalább egy edition-nel, melynek neve Ora$Base. Minden új edition egy már létezo gyermeke kell, hogy legyen. Amikor kapcsolódunk az adatbázishoz, meghatározható, hogy melyik edition-höz kapcsolódjunk. Kizárólag nézetek, szinonímák és PL/SQL ojektum típusoknak lehet több edíciója (ezek metadat típusú objektumok, nem tartalmaznak adatokat). Azok az objektumok, melyek több edícióval rendelkeznek egyedileg csak úgy azonosíthatók, ha az owner, name, namespace mellett az edition-t is megnevezzük. Azaz két vagy több példánya is létezhet egy adatbázison belül ugyanazzal az owner, name és namespace azonosítókkal rendelkezo objektumnak, amennyiben használjuk az edition-based redefinition-t. Egy új objektum típus, az editioning view is edicionálható. Mivel a fizikai tábla nem edicionálható (elkerülendo az adatok többszörös tárolását és teljesítmény gondokat), ezért az editioning view feladata egy adott tábla egyszeru leképezése egy nézet formájában, ami már több edition-ben is létezhet, és képes elfedni a tábla módosításait. Amennyiben a tábla módosítások olyan táblákat érintenek, amelyek tartalmát  az alkalmazás felhasználók módosítják, szükség van olyan triggerekre, amelyek az egyes editioning view-k között a módosításokat karbantartják. Ezek a crossedition triggerek. Természetesen ahhoz, hogy az online application upgrade muködjön, minden érintett tábla elé el kell készíteni az editioning nézetet és a megfelelo crossedition triggereket. Ezeket használva az alkalmazás két vagy több különbözo verzió képes ugyanazon adatbázison párhuzamosan futni, és ha megtörtént a verzióváltás, akkor még mindig egyszeru visszaállni a régi verzióra egészen addig, amíg a régi edition eldobásra nem kerül. További információk az Edition-Based Redefinition címu whitepaper-ben találhatók.

• JavaOne: Parleys.com, Spring Vs. Java EE and HTML5 tooling

  - by delabassee

  Parleys.com, a 2012 Duke's Choice Award winner, is an E-Learning platform that host content from different sources (conferences, JUGs meetings, etc.). There is a lot of technical content available for online but also offline consumption, including many sessions on Java EE. Parleys has just released, for free, all the Devoxx 2011 sessions (video and slides sync'ed!). From a technical point of view, Parleys.com is interesting as they have switched from Spring to Java EE 6 to avoid being locked in a proprietary framework. During the GlassFish Community BoF, Stephan Janssen (Parleys.com and Devoxx founder) also presented how GlassFish is used to support 2000 concurrent Parleys users over a cluster of 2 GlassFish instances. Talking about Java EE and/or Spring, Harshad Oak has posted an update on the 'Spring Vs. Java EE' panel discussion that took place on Tuesday. As Arun said standards such as Java EE does not necessarily refrain innovation: "JBoss Forge & Arquillian from RedHat are great examples of innovation in the JavaEE community. Standardization is important but innovation does continue even within that framework." Simplicity, productivity along with HTML5 are the driving themes of Java EE 7. In terms of simplicity and productivity, the developer experience can also be improved by the tooling. Every NetBeans release comes with a large set of improvements, the just released NetBeans 7.3 beta is no exception. The goal of ‘NB 7.3’s Project Easel’ is to improve HTML5 development, something that will be handy for Java EE 7 developers. Project Easel can, for example, communicate directly to Chrome's WebKit engine, this feature was shown during Sunday's Technical Keynote at the end of the Java EE section. In this beta release, Chrome and the embedded JavaFX browser are the only supported browsers but the NetBeans team plan to add support, over time, for other WebKit based browsers. NetBans 7.3 beta NetBeans 7.3 screenscasts Today (i.e. Wednesday 3rd) is also the final exhibition day, so make sure to visit the Java EE and the GlassFish pods on the Java DEMOgrounds (Hilton Grand Ballroom, 9:30 am - 5:00 pm).

• Using ASP.NET Membership Provider with an ACL

  - by geekrutherford

  Up until recently one of my applications has used the membership provider within ASP.NET exclusively. However, it has been proposed that while the currently defined roles are beneficial, security needs to be more granular to restrict both access to certain pages and functionality present within a given page.   Unfortunately, the role based security ASP.NET gives you out of the box falls down in this area. This is not due to a lack of foresight by Microsoft, but rather it was simply not designed for implementing both role based security and any inherent ACL you may define within these roles. Mind you some would say an ACL is independent of the role to which a user belongs and is assigned to the user directly.   The application mentioned here has it's own User object (which encapsulates the membership provider user object as a property) and SQL Server table to store extended information not present in the aspnet_users table. While I could have modified the aspnet membership schema to suit the applications needs, it seemed smarter to simply create a separate table with a foreign key back to the aspnet_users table.   Since I have a separate object to store extended user information, I simply created an ACL object and expose it as a property of my user object.   This is all well and good, but it does not help in regards to the SiteMapProvider and restricting access at the page level based on the users ACL.   The straightforward answer would be to develop some code within the databound event for the menu that checks the page title and has hardcoded logic that dictates a user must have certain permissions turned on. The problem with this approach is that it's HARDCODED!!! If you need to change access to a page you'd need to do a build and go through your normal deployment process....ugh!!!   An alternative method, albeit not perfect, is to utilize the resourceKey property on the SiteMapNodes in the SiteMap file with the name of the required permission to view the page. Within the databound event for your menu you iterate the SiteMapNodes in the menus SiteMapProvider looking for a match at the page level based on title. When a match is detected, you have a switch/case on the SiteMapNodes resourceKey (the name of the ACL permission required). The case for the resourceKey ensures the users ACL permission is turned on and viola!!!   This is noteably not perfect in that it is using the resourceKey in a manner other than intended.  Since the application is not localized, using it in the manner described it not an issue.   Below is a sample SiteMap file with the resourceKey used as the ACL permission identifier:     Below is the ItemDataBound event. This application uses the Telerik Menu control:

• Software Architecture and MEF composition location

  - by Leonardo

  Introduction My software (a bunch of webapi's) consist of 4 projects: Core, FrontWebApi, Library and Administration. Library is a code library project that consists of only interfaces and enumerators. All my classes in other projects inherit from at least one interface, and this interface is in the library. Generally speaking, my interfaces define either Entities, Repositories or Controllers. This project references no other project or any special dlls... just the regular .Net stuff... Core is a class-library project where concrete implementation of Entities and Repositories. In some cases i have more than 1 implementation for a Repository (ex: one for azure table storage and one for regular Sql). This project handles the intelligence (business rules mostly) and persistence, and it references only the Library. FrontWebApi is a ASP.NET MVC 4 WebApi project that implements the controllers interfaces to handle web-requests (from a mobile native app)... It references the Core and the Library. Administration is a code-library project that represents a "optional-module", meaning: if it is present, it provides extra-features (such as Access Control Lists) to the application, but if its not, no problem. Administration is also only referencing the Library and implementing concrete classes of a few interfaces such as "IAccessControlEntry"... I intend to make this available with a "setup" that will create any required database table or anything like that. But it is important to notice that the Core has no reference to this project... Development Now, in order to have a decoupled code I decide to use IoC and because this is a small project, I decided to do it using MEF, specially because of its advertised "composition" capabilities. I arranged all the imports/exports and constructors and everything, but something is quite not perfect in my "mental-visualisation": Main Question Where should I "Compose" the objects? I mean: Technically, the only place where real implementation access is required is in the Repositories, because in order to retrieve data from wherever, entities instances will be necessary, and in all other places. The repositories could also provide a public "GetCleanInstanceOf()" right? Then all other places will be just fine working with the interfaces instead of concrete classes... Secondary Question Should "Administration" implement the concrete object for "IAccessControlGeneralRepository" or the Core should?

• Should custom data elements be stored as XML or database entries?

  - by meteorainer

  There are a ton of questions like this, but they are mostly very generalized, so I'd like to get some views on my specific usage. General: I'm building a new project on my own in Django. It's focus will be on small businesses. I'd like to make it somewhat customizble for my clients so they can add to their customer/invoice/employee/whatever items. My models would reflect boilerplate items that all ModelX might have. For example: first name last name email address ... Then my user's would be able to add fields for whatever data they might like. I'm still in design phase and am building this myself, so I've got some options. Working on... Right now the 'extra items' models have a FK to the generic model (Customer and CustomerDataPoints for example). All values in the extra data points are stored as char and will be coerced/parced into their actual format at view building. In this build the user could theoretically add whatever values they want, group them in sets and generally access them at will from the views relavent to that model. Pros: Low storage overhead, very extensible, searchable Cons: More sql joins My other option is to use some type of markup, or key-value pairing stored directly onto the boilerplate models. This coul essentially just be any low-overhead method weather XML or literal strings. The view and form generated from the stored data would be taking control of validation and reoganizing on updates. Then it would just dump the data back in as a char/blob/whatever. Something like: <datapoint type='char' value='something' required='true' /> <datapoint type='date' value='01/01/2001' required='false' /> ... Pros: No joins needed, Updates for validation and views are decoupled from data Cons: Much higher storage overhead, limited capacity to search on extra content So my question is: If you didn't live in the contraints impose by your company what method would you use? Why? What benefits or pitfalls do you see down the road for me as a small business trying to help other small businesses? Just to clarify, I am not asking about custom UI elements, those I can handle with forms and template snippets. I'm asking primarily about data storage and retreival of non standardized data relative to a boilerplate model.

• Fraud and Anomaly Detection using Oracle Data Mining YouTube-like Video

  - by chberger

  I've created and recorded another YouTube-like presentation and "live" demos of Oracle Advanced Analytics Option, this time focusing on Fraud and Anomaly Detection using Oracle Data Mining.  [Note:  It is a large MP4 file that will open and play in place.  The sound quality is weak so you may need to turn up the volume.] Data is your most valuable asset. It represents the entire history of your organization and its interactions with your customers.  Predictive analytics leverages data to discover patterns, relationships and to help you even make informed predictions.   Oracle Data Mining (ODM) automatically discovers relationships hidden in data.  Predictive models and insights discovered with ODM address business problems such as:  predicting customer behavior, detecting fraud, analyzing market baskets, profiling and loyalty.  Oracle Data Mining, part of the Oracle Advanced Analytics (OAA) Option to the Oracle Database EE, embeds 12 high performance data mining algorithms in the SQL kernel of the Oracle Database. This eliminates data movement, delivers scalability and maintains security.  But, how do you find these very important needles or possibly fraudulent transactions and huge haystacks of data? Oracle Data Mining’s 1 Class Support Vector Machine algorithm is specifically designed to identify rare or anomalous records.  Oracle Data Mining's 1-Class SVM anomaly detection algorithm trains on what it believes to be considered “normal” records, build a descriptive and predictive model which can then be used to flags records that, on a multi-dimensional basis, appear to not fit in--or be different.  Combined with clustering techniques to sort transactions into more homogeneous sub-populations for more focused anomaly detection analysis and Oracle Business Intelligence, Enterprise Applications and/or real-time environments to "deploy" fraud detection, Oracle Data Mining delivers a powerful advanced analytical platform for solving important problems.  With OAA/ODM you can find suspicious expense report submissions, flag non-compliant tax submissions, fight fraud in healthcare claims and save huge amounts of money in fraudulent claims  and abuse.   This presentation and several brief demos will show Oracle Data Mining's fraud and anomaly detection capabilities.

• Database Security: The First Step in Pre-Emptive Data Leak Prevention

  - by roxana.bradescu

  With WikiLeaks raising awareness around information leaks and the harm they can cause, many organization are taking stock of their own information leak protection (ILP) strategies in 2011. A report by IDC on data leak prevention stated: Increasing database security is one of the most efficient and cost-effective measures an organization can take to prevent data leaks. By utilizing the data protection, access control, account management, encryption, log management, and other security controls inherent in the database management system, entities can institute first-level control over the widest range of protected information. As a central repository for unstructured data, which is growing at leaps and bounds, the database should be the first layer providing information leakage protection. Unfortunately, most organizations are not taking sufficient steps to protect their databases according to a survey of the Independent Oracle User Group. For example, any operating system administrator or database administrator can access the all the data stored in the database in most organizations. Without any kind of auditing or monitoring. And it's not just administrators, database users can typically access the database with ad-hoc query tools from their desktop and by-pass any application level controls. Despite numerous regulations calling for controls to limit the powers of insiders, most organizations still put too many privileges in the hands of their employees. Time and time again these excess privileges have backfired. Internal agents were implicated in almost half of data breaches according to the Verizon Data Breach Investigations Report and the rate is rising. Hackers also took advantage of these excess privileges very successfully using stolen credentials and SQL injection attacks. But back to the insiders. Who are these insiders and why do they do it? In 2002, the U.S. Secret Service (USSS) behavioral psychologists and CERT information security experts formed the Insider Threat Study team to examine insider threat cases that occurred in US critical infrastructure sectors, and examined them from both a technical and a behavioral perspective.
