    - by Rajesh Sankar R
    This question already has an answer here: How to choose a CMS system for a small web site? 4 answers I am planning on setting up a website where I will be posting "how to or training videos" for various softwares. There will be several training videos under a single topic. And there will be several topics under a single software training. Similar to lynda.com but in a small scale. Can you suggest me a CMS for the job? Initially I am planning on hosting videos on YouTube and linking them to my website. But, I will be moving to my own hosting later on. It must be customizable, scalable, and most of all OPEN SOURCE

  • Using Stored Procedures in SSIS

    - by dataintegration
    The SSIS Data Flow components: the source task and the destination task are the easiest way to transfer data in SSIS. Some data transactions do not fit this model, they are procedural tasks modeled as stored procedures. In this article we show how you can call stored procedures available in RSSBus ADO.NET Providers from SSIS. In this article we will use the CreateJob and the CreateBatch stored procedures available in RSSBus ADO.NET Provider for Salesforce, but the same steps can be used to call a stored procedure in any of our data providers. Step 1: Open Visual Studio and create a new Integration Services Project. Step 2: Add a new Data Flow Task to the Control Flow window. Step 3: Open the Data Flow Task and add a Script Component to the data flow pane. A dialog box will pop-up allowing you to select the Script Component Type: pick the source type as we will be outputting columns from our stored procedure. Step 4: Double click the Script Component to open the editor. Step 5: In the "Inputs and Outputs" settings, enter all the columns you want to output to the data flow. Ensure the correct data type has been set for each output. You can check the data type by selecting the output and then changing the "DataType" property from the property editor. In our example, we'll add the column JobID of type String. Step 6: Select the "Script" option in the left-hand pane and click the "Edit Script" button. This will open a new Visual Studio window with some boiler plate code in it. Step 7: In the CreateOutputRows() function you can add code that executes the stored procedures included with the Salesforce Component. In this example we will be using the CreateJob and CreateBatch stored procedures. You can find a list of the available stored procedures along with their inputs and outputs in the product help. //Configure the connection string to your credentials String connectionString = "Offline=False;user=myusername;password=mypassword;access token=mytoken;"; using (SalesforceConnection conn = new SalesforceConnection(connectionString)) { //Create the command to call the stored procedure CreateJob SalesforceCommand cmd = new SalesforceCommand("CreateJob", conn); cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(new SalesforceParameter("ObjectName", "Contact")); cmd.Parameters.Add(new SalesforceParameter("Action", "insert")); //Execute CreateJob //CreateBatch requires JobID as input so we store this value for later SalesforceDataReader rdr = cmd.ExecuteReader(); String JobID = ""; while (rdr.Read()) { JobID = (String)rdr["JobID"]; } //Create the command for CreateBatch, for this example we are adding two new rows SalesforceCommand batCmd = new SalesforceCommand("CreateBatch", conn); batCmd.CommandType = CommandType.StoredProcedure; batCmd.Parameters.Add(new SalesforceParameter("JobID", JobID)); batCmd.Parameters.Add(new SalesforceParameter("Aggregate", "<Contact><Row><FirstName>Bill</FirstName>" + "<LastName>White</LastName></Row><Row><FirstName>Bob</FirstName><LastName>Black</LastName></Row></Contact>")); //Execute CreateBatch SalesforceDataReader batRdr = batCmd.ExecuteReader(); } Step 7b: If you had specified output columns earlier, you can now add data into them using the UserComponent Output0Buffer. For example, we had set an output column called JobID of type String so now we can set a value for it. We will modify the DataReader that contains the output of CreateJob like so:. while (rdr.Read()) { Output0Buffer.AddRow(); JobID = (String)rdr["JobID"]; Output0Buffer.JobID = JobID; } Step 8: Note: You will need to modify the connection string to include your credentials. Also ensure that the System.Data.RSSBus.Salesforce assembly is referenced and include the following using statements to the top of the class: using System.Data; using System.Data.RSSBus.Salesforce; Step 9: Once you are done editing your script, save it, and close the window. Click OK in the Script Transformation window to go back to the main pane. Step 10: If had any outputs from the Script Component you can use them in your data flow. For example we will use a Flat File Destination. Configure the Flat File Destination to output the results to a file, and you should see the JobId in the file. Step 11: Your project should be ready to run.

  • How to make openJDK automatically update-alternatives?

    - by cgc512
    Well, I've made a fresh Ubuntu 11.10 install and I installed openJDK 7. It updated alternatives just after installing, so it was all good. Then, I compiled a source and executed it and it didn't worked, then I noticed that java was using the version 1.6, while the javac was 1.7. I thought I had installed it wrong, so I uninstalled it and installed it again. But now, it does not update alternatives automatically (it does it only for javaws). Is there a way to "restart" it so the apt-get does the update-alternatives by itself like the first time? Is it normal that it uses the java 1.6 instead of the java 1.7 when installing openJDK 7? Thank you very much!

  • How to remove tearing in videos with Nvidia driver?

    - by Daimon
    I'm using ubuntu 11.10 as my HTPC OS on ION board. Tearing was always a big problem but this guide (http://www.omgubuntu.co.uk/2010/01/how-to-fix-video-tearing-in-videos-nvidia-ubuntu/) used to solve it in previous versions. I mean it used to because it doesn't solve it anymore. I tried making same changes (although compiz config is little different and same options are in different panels) but with no success. I also tried to manually set resolution and refresh rate of HDTV in nvidia settings - no changes at all. I know that open source drivers would solve a problem but it's not an option because I need VDPAU acceleration. I've also read that completely disabling of Composite solves the problem - can't do that because compizconfig-settings-manager crashes on attempt.

  • Microsoft Forcing Dev/Partners Hands on Win 8 Through Certification

    - by D'Arcy Lussier
    I remember 2.5 years ago when Microsoft dropped a bomb on the Microsoft Partner community: all Gold competencies would require .NET 4 based premiere certifications (MCPD). Problem was, this gave a window of about 6 months for partners to update their employees’ certifications. At the place I was working, I put together an aggressive plan and we were able to attain the certs needed. Microsoft is always open that the certification requirements will change as the industry changes. .NET 1.0 certifications are useless here in 2012, and rightfully so they’ve been retired for a long time now. But now we’re seeing a new tactic by Microsoft – shifting gears away from certifications that speak to what industry needs and more to the Windows 8 agenda. Consider that currently the premiere development certification is the Microsoft Certified Professional Developer, which comes in three flavours – Web, Windows, and Azure. All require WCF and Data Access exams, as well as one that deals with the associated base technologies (ASP.NET, WinForms/WPF, Azure), and one that ties all three together in a solution-based exam. For Microsoft-based organizations, these skills aren’t just valid but necessary in building Microsoft applications. But the MCPD is being replaced with our old friend Microsoft Certified Solutions Developer (MCSD). So far, Microsoft has only released two types of MCSD – Web and Windows Store Apps. Windows Store Apps?! In a push to move developers to create WinRT-based applications, desktop development is now considered a second-class citizen in the eyes of Redmond. Also interesting are the language options for the exams: HTML5 and C#. Sorry VB folks, its time to embrace curly braces whether they be JavaScript or C#. Consider too the skills being assessed for the Windows Store Apps: Get your MCSD: Windows Store Apps Using HTML5 Get your MCSD: Windows Store Apps Using C# *Image Source: http://www.microsoft.com/learning/en/us/certification/mcsd-windows-store-apps.aspx Nov 21/2012 If you look at the skills being tested in each exam, you’ll find that skills like WCF and Data Access are downplayed compared to things like integrating Charms, facilitating Search, programming for the microphone and camera – all very Windows 8 focussed items. Where this becomes maddening is that Microsoft is still pushing Windows 7 with enterprise clients. According to a ZDNet article, Microsoft wants to see Windows 7 on 70% of enterprise desktops by mid 2013. Assuming they somehow meet that (its a pretty lofty goal), there’s years of traditional desktop-based development that will still be required at some level. For those thinking they’ll just write and stick with the MCPD certification, note that most exams that go towards that certification will be retired at the end of July 2013! (Read the small print). And while details haven’t been finalized, its a safe bet that MCPD certifications eventually won’t count towards Gold-level competencies in the Microsoft Partner program. What this means for Microsoft Partners and Developers is that certification for desktop development is going to be limited to Windows Store Apps unless Microsoft re-introduces a traditional desktop (WPF) based MCSD cert. Web Application Development – It’s Not All Bad There’s big changes on the web side of certification, but I actually see these changes as being for the good! Check out the new exam requirements for MCSD – Web Applications: Get your MCSD: Web Applications certification *Image Source: http://www.microsoft.com/learning/en/us/certification/cert-mcsd-web-applications.aspx Nov 21, 2012 We now *start* with HTML5, JavaScript, and CSS3! Now I’m sure that these will be slanted towards web development in IE, and I can hear designers everywhere bemoaning the CSS/IE combination. Still, I applaud Microsoft for adopting HTML5 as the go-to web technology and requiring certified developers to prove they have skills in the basics of web dev. The fact that the second exam clearly states “MVC Web Applications” shows that Web Forms is truly legacy and deprecated. That’s not to say there aren’t those out there that are still supporting or (for whatever reason) doing new dev with Web Forms, but this move by Microsoft is telling the community they better get on the MVC bandwagon if they want to stay current. Fantastic! And of course Azure needs to be here as well, and this is where the Microsoft agenda fits in. It’s no secret that there’s been a huge push in getting developers on to Azure. I don’t see this as being a bad thing either, as cloud computing (whether Azure, private, or 3rd party) is a necessary skill for developers to have here in 2012. The cynic in me realizes that the HTML5/JavaScript/CSS push wouldn’t be as prominent though if not for the Windows 8 Store App play, where HTML5 is a first class citizen (and an available language for the MCSD Windows Store App cert). In this case, the desktop developers loss is the web developers gain. Get Ready for Changes In addition to the changes in certifications, the Microsoft Partner competencies are going through changes as well. Web and Software Development are being merged into a single competency, meaning that licenses you would have received from having both as Gold are reduced. Other competencies are either being removed or changed, as are the exam requirements. In the same way that we’re seeing faster release cycles from Microsoft, so too will we see the Microsoft Partner Program and MS Certifications evolve faster than ever before. Many of us got caught in the last wave of changes, but this time we can see the wave coming – and it looks pretty big!

  • Dell Vostro 2420 upgrade to 12.04.1 no wifi

    - by Kane
    I have installed 12.04 on a dell vostro 2420 (previously 11.10) and wifi is gone now but wired network remains. I've reviewed the other questions and tried some stuff but no luck yet. The following is the process so far so hopefully someone can help: After installing 12.04 using the additional drivers utility did not bring up any proprietary drivers and using synaptic on installation then reinstallation of bcmwl-kernel-source and b43-fwcutter does not help bring up any drivers either (tried rebooting after as well) I have made sure in the bios that the wlan is turned on, and it appears the laptop does not have a wireless hardware switch, only the keyboard function shortcut which turns bluetooth on and off on the taskbar but there is no lightup of the wireless function on the laptop itself. Dell does not appear to have any drivers for ubuntu and google does not appear to be much help :( Thanks in advance!

  • design pattern for unit testing?

    - by Maddy.Shik
    I am beginner in developing test cases, and want to follow good patterns for developing test cases rather than following some person or company's specific ideas. Some people don't make test cases and just develop the way their senior have done in their projects. I am facing lot problems like object dependencies (when want to test method which persist A object i have to first persist B object since A is child of B). Please suggest some good books or sites preferably for learning design pattern for unit test cases. Or reference to some good source code or some discussion for Dos and Donts will do wonder. So that i can avoid doing mistakes be learning from experience of others.

  • Thunderbird adds ***UNCHECKED*** to subjects of GPG messages

    - by Roman Geber
    Thunderbird seems to consider it a great idea to add the string UNCHECKED in front of the subject of GPG encrypted messages. Well, its not a good idea but rather annoying. At first I thought it would be a mailserver thing, so I checked. No trace of it, anywhere. Same goes for the raw message source. When I look at it the subject appears untouched, therefore I assume its a Thunderbird thing. Does anyone know an option to turn this ill behavior off? Thanks a lot in advance! cu Roman

  • Why are the packages found with apt-get always horribly out of date?

    - by Andrew
    Whenever I use the package manager, it can only ever find really old versions of stuff. Example: sudo apt-get update sudo apt-get install postgresql The best it can do is version 8.4 (3 years out of date). Trying to get a later version, I get: $ sudo apt-get install postgresql-9.1 Reading package lists... Done Building dependency tree Reading state information... Done E: Couldn't find package postgresql-9.1 I experience the same issue whenever I use the package manager, so I usually just download and build things from source. How can I make it find up-to-date software?

  • How to change sample text in font installer

    - by Tony Martin
    I have several Japanese fonts but do not want to install them all. I would like to preview them before installing. In icon view I can get a very rough idea of the style of the font as it shows Aa. When I open the font I am presented with a dialog box which shows a sample of the font with the sentence The quick brown fox jumped over the lazy dog. I would like to change this sample text to Japanese text to get a fuller preview of the font. Is it at all possible? I suspect I might have to edit and compile source, not something I'm very familiar with.

  • Passing Parameters Between Web-Services and JSF Pages

    - by shay.shmeltzer
    This is another quick demo that shows a common scenario that combines several demos I did in the past. The scenario – we have two web services, one returns a list of objects, the other allows us to update an object. We want to build a page flow where the first page shows us the list of objects, allows us to select one, and then we can edit that instance in the next page and call the second web service to update our data source. The demo shows: How to select a row and save the object value in a pageFlowScope. (using setPropertyListener). How to create a page that allows me to modify the value of the pageFlowScope object, and how to pass the object as a parameter to the second Web service. Check it out here:

  • LGPL License in commercial application

    - by Jacob
    I have searched around but I don't seem to be able to get a clear answer on my questions that I understand. I want to use the Xuggler library in my application, which is licensed either GPL or LGPL depending on whether I compile it myself. I don't intend to edit the library If I compile it myself and thus get a LGPL version of the library, can I use it in a commercial application without having to distribute the source code of my application? Furthermore, do I have to give my application the LGPL license as well? What other problems might using this library give me?

  • How do I include Implementation and Usage Documentation in one file

    - by Angelo.Hannes
    There are two types of documentation. One type, the Implementation Documentation, contains information about specific implementation of a construct (eg. Class, Method, etc.). It is targeted to the future me, maintainer, debugger and so on. And there is Usage Documentation, containing information how to use a provided api. It does not contain information about specific implementation and is targeted to users of the api. How do I include both of them in one file? (Or do I include both of them in one file? And if not, what type belongs into the source file?) Are there special techniques, using java-doc and/or best practices?

  • Is it needed to have your blog title and description in H1 and H2

    - by Saif Bechan
    I have read an article that states that it is not necessary to have your blog title and description on your website at all. Just have the titles of the posts in h1, on the index and the post page. And on the post page have your different sections started with h2. Widget headers start with h3. Title and description are most of the time in the logo image. I have looked at the source of my favorite blog, http://net.tutsplus.com, and I see they do the same. Is this recommended?

  • A Visual Studio Release Grows in Brooklyn

    - by andrewbrust
    Yesterday, Microsoft held its flagship launch event for Office 2010 in Manhattan.  Today, the Redmond software company is holding a local launch event for Visual Studio (VS) 2010, in Brooklyn.  How come information workers get the 212 treatment and developers are relegated to 718? Well, here’s the thing: the Brooklyn Marriott is actually a great place for an event, but you need some intimate knowledge of New York City to know that.  NBC’s Studio 8H, where the Office launch was held yesterday (and from where SNL is broadcast) is a pretty small venue, but you’d need some inside knowledge to recognize that.  Likewise, while Office 2010 is a product whose value is apparent.  Appreciating VS 2010’s value takes a bit more savvy.  Setting aside its year-based designation, this release of VS, counting the old Visual Basic releases, is the 10th version of the product.  How can a developer audience get excited about an integrated development environment when it reaches double-digit version numbers?  Well, it can be tough.  Luckily, Microsoft sent Jay Schmelzer, a Group Program Manager from the Visual Studio team in Redmond, to come tell the Brooklyn audience why they should be excited. Turns out there’s a lot of reasons.  Support fro SharePoint development is a big one.  In previous versions of VS, that support has been anemic, at best.  Shortage of SharePoint developers is a huge issue in the industry, and this should help.  There’s also built in support for Windows Azure (Microsoft’s cloud platform) and, through a download, support for the forthcoming Windows Phone 7 platform.  ASP.NET MVC, a “close-to-the-metal” Web development option that does away with the Web Forms abstraction layer, has a first-class presence in VS.  So too does jQuery, the Open Source environment that makes JavaScript development a breeze.  The jQuery support is so good that Microsoft now contributes to that Open Source project and offers IntelliSense support for it in the code editor. Speaking of the VS code editor, it now supports multi-monitor setups, zoom-in, and block selection.  If you’re not a developer, this may sound confusing and minute.  I’ll just say that for people who are developers these are little things that really contribute to productivity, and that translates into lower development costs. The really cool demo, though, was around Visual Studio 2010’s new debugging features.  This stuff is hard to showcase, but I believe it’s truly breakthrough technology: imagine being able to step backwards in time to see what might have caused a bug.  Cool?  Now imagine being able to do that, even if you weren’t the tester and weren’t present while the testing was being done.  Then imagine being able to see a video screen capture of what the tester was doing with your app when the bug occurred.  VS 2010 allows all that.  This could be the demise of the IWOMM (“it works on my machine”) syndrome. After the keynote, I asked Schmelzer if any of Microsoft’s competitors have debugging tools that come close to VS 2010’s.  His answer was an earnest “we don’t think so.”  If that’s true, that’s a big deal, and a huge advantage for developer teams who adopt it.  It will make software development much cheaper and more efficient.  Kind of like holding a launch event at the Brooklyn Marriott instead of 30 Rock in Manhattan! VS 2010 (version 10) and Office 2010 (version 14) aren’t the only new product versions Microsoft is releasing right now.  There’s also SQL Server 2008 R2 (version 10.5), Exchange 2010 (version 8, I believe), SharePoint 2010 (version 4) and, of course, Windows 7.  With so many new versions at such levels of maturity, I think it’s fair to say Microsoft has reached middle-age.  How does a company stave off a potential mid-life crisis, especially when with young Turks like Google coming along and competing so fiercely?  Hard to say.  But if focusing on core value, including value that’s hard to play into a sexy demo, is part oft the answer, then Microsoft’s doing OK.  And if some new tricks, like Windows Phone 7, can gain some traction, that might round things out nicely. Are the legacy products old tricks, or are they revised classics?  I honestly don’t know, because it’s the market’s prerogative to pass that judgement.  I can say this though: based on today’s show, I think Microsoft’s been doing its homework.

    I made a link on my Desktop to the launcher file "Compiz" in /usr/share/applications/. When I try to execute it I get: "The application launcher "Link to compiz.desktop" has not been marked as trusted. If you do not know the source of this file, launching it may be unsafe." So my question is how to make such a launcher on my Desktop? Otherwise, what kind of file are these [Desktop Entry] files and how can they be executed (by double clicking on them) if they have permissions such as: -rw-r--r-- 1 root root 396 2010-12-17 15:23 compiz.desktop

  • The next step for a graduate?

    - by Michael Hobbs
    I will complete my degree in Computer Science in July of 2013 however I will have two years of military service left. I would like to get some hands on C#/C++ programming experience in the mean time. I have been looking around the web at all the open source project that are out there. There are literally 10's of thousands. How would you go about picking one that is: A) good for a graduate level programmer B) will probably go somewhere, and C) are willing to take a novice under their wing. I would even be happy to work for a company for free, remotely as a debugger, tester, or what have you. As a side note would prefer to stick in the C# realm but understand I need to branch out at the same time.

  • Bug Tracking Etiquette - Necromancy or Duplicate?

    - by Shauna
    I came across a really old (2+ years) feature request issue in a bug tracker for an open source project that was marked as "resolved (won't fix)" due to the lack of tools required to make the requested enhancement. In the time elapsed since that determination was made, new tools have been developed that would allow it to be resolved, and I'd like to bring that to the attention of the community for that application. However, I'm not sure as to what the generally accepted etiquette is for bug tracking in cases like this. Obviously, if the system explicitly states to not duplicate and will actively mark new items as duplicates (much in the way the SE sites do), then the answer would be to follow what the system says. But what about when the system doesn't explicitly say that, or a new user can't easily find a place that says with the system's preference is? Is it generally considered better to err on the side of duplication or necromancy? Does this differ depending on whether it's a bug or a feature request?

  • Can I use Google Search to determine if my website contains original or copied content?

    - by Bas van Vught
    I have a few websites from customers that have (partially) the same content as other websites. I plan on rewriting all content that is not original, but how do I know if my websites have original content, or content that's been copied from another website? My customers say all the content is original, but I have my doubts to be honest. They often let other people who don't work there anymore write content for the sites. What I did so far is copy a line from my website that can be found in other websites as well and pasted it into Google Search. If my website is the first link, would it be considered the original source?

  • How to disable Alert volume from the command line in Natty?

    - by Bryce
    There is an option in the Sound Preferences dialog, Sound Effects tab, to toggle Alert volume 'mute'. It works and suffices for my needs to disable the irritating system beep/bell. However, I reinstall systems a LOT for testing purposes and would like to set this setting in a shell script so it's off without having to fiddle with a GUI. But for the life of me I can't seem to find where this can be toggled via a command line tool. I've scanned through gconf-editor, pulseaudio's pacmd, grepped through /etc, even dug through the gnome-volume-control source code, but I am not seeing how this can be set. I gather that gnome-volume-control has changed since a few releases ago. I'm using Natty fwiw. Ideas?

But sometimes you have to, so here are a couple of things to bear in mind: Schemas Point a codegen tool at a WCF endpoint which exposes a DataSet and it will generate an XSD which describes the DataSet like this: <xs:elementminOccurs="0"name="GetDataSetResult"nillable="true">  <xs:complexType>     <xs:annotation>       <xs:appinfo>         <ActualTypeName="DataSet"                     Namespace="http://schemas.datacontract.org/2004/07/System.Data"                     xmlns="http://schemas.microsoft.com/2003/10/Serialization/" />       </xs:appinfo>     </xs:annotation>     <xs:sequence>       <xs:elementref="xs:schema" />       <xs:any />     </xs:sequence>  </xs:complexType> </xs:element>  In a serialized instance, the element of type xs:schema contains a full schema which describes the structure of the DataSet – tables, columns etc. The second element, of type xs:any, contains the actual content of the DataSet, expressed as DiffGrams: <GetDataSetResult>  <xs:schemaid="NewDataSet"xmlns:xs="http://www.w3.org/2001/XMLSchema"xmlns=""xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">     <xs:elementname="NewDataSet"msdata:IsDataSet="true"msdata:UseCurrentLocale="true">       <xs:complexType>         <xs:choiceminOccurs="0"maxOccurs="unbounded">           <xs:elementname="Table1">             <xs:complexType>               <xs:sequence>                 <xs:elementname="Id"type="xs:string"minOccurs="0" />                 <xs:elementname="Name"type="xs:string"minOccurs="0" />                 <xs:elementname="Date"type="xs:string"minOccurs="0" />               </xs:sequence>             </xs:complexType>           </xs:element>         </xs:choice>       </xs:complexType>     </xs:element>  </xs:schema>  <diffgr:diffgramxmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1"xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">     <NewDataSetxmlns="">       <Table1diffgr:id="Table11"msdata:rowOrder="0"diffgr:hasChanges="inserted">         <Id>377fdf8d-cfd1-4975-a167-2ddb41265def</Id>         <Name>157bc287-f09b-435f-a81f-2a3b23aff8c4</Name>         <Date>a5d78d83-6c9a-46ca-8277-f2be8d4658bf</Date>       </Table1>     </NewDataSet>  </diffgr:diffgram> </GetDataSetResult> Put the XSD into a BizTalk schema and it will fail to compile, giving you error: The 'http://www.w3.org/2001/XMLSchema:schema' element is not declared. You should be able to work around that, but I've had no luck in BizTalk Server 2006 R2 – instead you can safely change that xs:schema element to be another xs:any type: <xs:elementminOccurs="0"name="GetDataSetResult"nillable="true">  <xs:complexType>     <xs:sequence>       <xs:any />       <xs:any />     </xs:sequence>  </xs:complexType> </xs:element>  (This snippet omits the annotation, but you can leave it in the schema). For an XML instance to pass validation through the schema, you'll also need to flag the any attributes so they can contain any namespace and skip validation:  <xs:elementminOccurs="0"name="GetDataSetResult"nillable="true">  <xs:complexType>     <xs:sequence>       <xs:anynamespace="##any"processContents="skip" />       <xs:anynamespace="##any"processContents="skip" />     </xs:sequence>  </xs:complexType> </xs:element>  You should now have a compiling schema which can be successfully tested against a serialised DataSet. Transforms If you're mapping a DataSet element between schemas, you'll need to use the Mass Copy Functoid to populate the target node from the contents of both the xs:any type elements on the source node: This should give you a compiled map which you can test against a serialized instance. And if you have a .NET consumer on the other side of the mapped BizTalk output, it will correctly deserialize the response into a DataSet.
