• Encryption container for multiple people

  - by Adam M.

  I was just wondering if anyone may have come across a product that would allow for a container based encryption to be used by multiple people, in a Windows Server setup. I wanted to see if there might be something like a truecrypt that could handle being accessed by two accounts? Looking to see if there is a product that would have such properties that would allow only a hand full of users access to the content of the location, but allow for the files to be backed up a normal backup system. That way if a file had to be restored, the container could be redirected to another location for one of the users to get access to it? This would allow for access to be restricted beyond the NTFS and file share permissons

• Can a PCI Graphics card, and AGP be used together? [closed]

  - by Everyone

  The question pretty much says it all. I use an old 845GBV board ( to-date reliant upon the integrated graphics processor ). All slots on the board are unused. Lately I've been thinking in terms changing it to a dual monitor so that I can use one console for documentation/help/sample code/whatever, the other one to play with code. Assuming this board can handle a PCI GPU, can an AGP4x board coexist with a PCI GPU?

• Windows Update and IE fail to connect, but Chrome fine?

  - by I Gottlieb

  Out of ideas on this one. (Running Windows Vista.) I have a program that accesses the internet to retrieve financial market data. One day it tells me that it can't log in -- timeout error. I check the documentation and it says must have a working copy of IE browser installed. I check IE (have IE9) and sure enough -- it just spins. No error message, not timeout, no 'try later' -- just spins -- as far as I can tell, indefinitely. Any page, any address. Even access to a localhost site just spins. Chrome works fine. So does another program I have that fetches market data. Windows 'diagnose and repair' says my internet connection is working fine. I tried uninstall/re-install of IE. Same spinning. I tried to install Windows Updates, and guess what? I can't. I comes up with error 80072efd; checked documentation for the error and it says I should check firewall blockage. Thing is, the only firewall I have is Windows Firewall, and obviously it wouldn't be blocking Windows Update. In contrast, Windows 'Help' in all programs has no problem accessing the Internet. I had a filter on the internet connection, and this was updated just prior to first appearance of the problem. But I uninstalled the filter entirely (official, with passwd from the company's service rep) -- and no difference. I'm guessing that a high level Windows network service file is corrupted -- used only by MS programs and their ilk, but how do I find it? I'd like to avoid having to do a clean install of Windows. Much obliged for any insight. IG Ramhound -- Thanks for reply. I'm familiar with virtual machines as in e.g. JVM or an emulator for an alternative architecture or (theoretical) Turing Machine equivalence. But I'm not familiar with the way you're using the term. Please clarify -- what one needs for this VM 'test' and why you expect it will provide an advantage of insight into the problem. And what sort of 'configuration issue' are you referring to? IG

• Computer won't stay powered up

  - by Android

  I have just tried to turn my PC on this morning and it won't stay powered up. It will come on as normal for about 5 seconds, not quite long enough for the monitor to wake up. Then it will power off. After about 2 seconds it will start again, it will continue like this until I pull out the plug. Plugging it in again doesn't restart the cycle although pressing the power button does. I have tried to clear the cmos but beyond that I have no ideas. It was working perfectly when I put it in hibernate last night. NOTE: I am using a Dell Optiplex 755 UPDATE 1: I took out the motherboard battery and it almost came on then it displays the message Error loading Operating System UPDATE 2: After taking out the custom video card, it says "No hard drive present"

• How can I manage hostnames across multiple servers? [closed]

  - by Dan

  In a lot of documentation I've seen recently, servers are referred to by internal hostnames, such as production-1, production-2, db-1. I realize I can associate these names in the hosts file on the server, but this would obviously mean maintaining a host file for multiple servers, which for anything greater than 2 or 3 would get unwieldy. Is there some simple way people manage common hostnames across multiple servers and keep them in sync, without having to edit multiple files every time?

• How to change default user (ubuntu) via CloudInit on AWS

  - by Gui Ambros

  I'm using CloudInit to automate the startup of my instances on AWS. I followed the (scarce) documentation available at http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/annotate/head%3A/doc/examples/cloud-config.txt and examples on /usr/share/doc/cloud-init, but still haven't figured out how to change the default username (ubuntu, id:1000). I know I can create a script to manually delete the default ubuntu and add my user, but seems counter intuitive given that CloudInit exist exactly to automate the initial setup. Any ideas?

• Getting started with Exchange Web Services 2010

  - by Adam Tuttle

  I've been tasked with writing a SOAP web-service in .Net to be middleware between EWS2010 and an application server that previously used WebDAV to connect to Exchange. (As I understand it, WebDAV is going away with EWS2010, so the application server will no longer be able to connect as it previously did, and it is exponentially harder to connect to EWS without WebDAV. The theory is that doing it in .Net should be easier than anything else... Right?!) My end goal is to be able to get and create/update email, calendar items, contacts, and to-do list items for a specified Exchange account. (Deleting is not currently necessary, but I may build it in for future consideration, if it's easy enough). I was originally given some sample code, which did in fact work, but I quickly realized that it was outdated. The types and classes used appear nowhere in the current documentation. For example, the method used to create a connection to the Exchange server was: ExchangeService svc = new ExchangeService(); svc.Credentials = new WebCredentials(AuthEmailAddress, AuthEmailPassword); svc.AutodiscoverUrl(AutoDiscoverEmailAddress); For what it's worth, this was using an assembly that came with the sample code: Microsoft.Exchange.WebServices.dll ("MEWS"). Before I realized that this wasn't the current standard way to accomplish the connection, and it worked, I tried to build on it and add a method to create calendar items, which I copied from here: static void CreateAppointment(ExchangeServiceBinding esb) { // Create the appointment. CalendarItemType appointment = new CalendarItemType(); ... } Right away, I'm confronted with the difference between ExchangeService and ExchangeServiceBinding ("ESB"); so I started Googling to try and figure out how to get an ESB definition so that the CreateAppointment method will compile. I found this blog post that explains how to generate a proxy class from a WSDL, which I did. Unfortunately, this caused some conflicts where types that were defined in the original Assembly, Microsoft.Exchange.WebServices.dll (that came with the sample code) overlapped with Types in my new EWS.dll assembly (which I compiled from the code generated from the services.wsdl provided by the Exchange server). I excluded the MEWS assembly, which only made things worse. I went from a handful of errors and warnings to 25 errors and 2,510 warnings. All kinds of types and methods were not found. Something is clearly wrong, here. So I went back on the hunt. I found instructions on adding service references and web references (i.e. the extra steps it takes in VS2008), and I think I'm back on the right track. I removed (actually, for now, just excluded) all previous assemblies I had been trying; and I added a service reference for https://my.exchange-server.com/ews/services.wsdl Now I'm down to just 1 error and 1 warning. Warning: The element 'transport' cannot contain child element 'extendedProtectionPolicy' because the parent element's content model is empty. This is in reference to a change that was made to web.config when I added the service reference; and I just found a fix for that here on SO. I've commented that section out as indicated, and it did make the warning go away, so woot for that. The error hasn't been so easy to get around, though: Error: The type or namespace name 'ExchangeService' could not be found (are you missing a using directive or an assembly reference?) This is in reference to the function I was using to create the EWS connection, called by each of the web methods: private ExchangeService getService(String AutoDiscoverEmailAddress, String AuthEmailAddress, String AuthEmailPassword) { ExchangeService svc = new ExchangeService(); svc.Credentials = new WebCredentials(AuthEmailAddress, AuthEmailPassword); svc.AutodiscoverUrl(AutoDiscoverEmailAddress); return svc; } This function worked perfectly with the MEWS assembly from the sample code, but the ExchangeService type is no longer available. (Nor is ExchangeServiceBinding, that was the first thing I checked.) At this point, since I'm not following any directions from the documentation (I couldn't find anywhere in the documentation that said to add a service reference to your Exchange server's services.wsdl -- but that does seem to be the best/farthest I've gotten so far), I feel like I'm flying blind. I know I need to figure out whatever it is that should replace ExchangeService / ExchangeServiceBinding, implement that, and then work through whatever errors crop up as a result of that switch... But I have no idea how to do that, or where to look for how to do it. Googling "ExchangeService" and "ExchangeServiceBinding" only seem to lead back to outdated blog posts and MSDN, neither of which has proven terribly helpful thus far. Help me, Obi-Wan, you're my only hope!

• Qt - drag and drop with graphics view framework

  - by David Davidson

  I'm trying to make a simple draggable item using the graphics framework. Here's the code for what I did so far: Widget class: class Widget : public QWidget { Q_OBJECT public: Widget(QWidget *parent = 0); ~Widget(); }; Widget::Widget(QWidget *parent) : QWidget(parent) { DragScene *scene = new DragScene(); DragView *view = new DragView(); QHBoxLayout *layout = new QHBoxLayout(); DragItem *item = new DragItem(); view->setAcceptDrops(true); scene->addItem(item); view->setScene(scene); layout->addWidget(view); this->setLayout(layout); } Widget::~Widget() { } DragView class: class DragView : public QGraphicsView { public: DragView(QWidget *parent = 0); }; DragView::DragView(QWidget *parent) : QGraphicsView(parent) { setRenderHints(QPainter::Antialiasing); } DragScene class: class DragScene : public QGraphicsScene { public: DragScene(QObject* parent = 0); protected: void dragEnterEvent(QGraphicsSceneDragDropEvent *event); void dragMoveEvent(QGraphicsSceneDragDropEvent *event); void dragLeaveEvent(QGraphicsSceneDragDropEvent *event); void dropEvent(QGraphicsSceneDragDropEvent *event); }; DragScene::DragScene(QObject* parent) : QGraphicsScene(parent) { } void DragScene::dragEnterEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dragMoveEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dragLeaveEvent(QGraphicsSceneDragDropEvent *event){ } void DragScene::dropEvent(QGraphicsSceneDragDropEvent *event){ qDebug() << event->pos(); event->acceptProposedAction(); DragItem *item = new DragItem(); this->addItem(item); item->setPos(event->pos()); } DragItem class: class DragItem : public QGraphicsItem { public: DragItem(QGraphicsItem *parent = 0); QRectF boundingRect() const; void paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget = 0); protected: void mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event); void mouseMoveEvent(QGraphicsSceneMouseEvent *event); void mousePressEvent(QGraphicsSceneMouseEvent *event); void mouseReleaseEvent(QGraphicsSceneMouseEvent *event); }; DragItem::DragItem(QGraphicsItem *parent) : QGraphicsItem(parent) { setFlag(QGraphicsItem::ItemIsMovable); } QRectF DragItem::boundingRect() const{ const QPointF *p0 = new QPointF(-10,-10); const QPointF *p1 = new QPointF(10,10); return QRectF(*p0,*p1); } void DragItem::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget){ if(painter == 0) painter = new QPainter(); painter->drawEllipse(QPoint(0,0),10,10); } void DragItem::mouseDoubleClickEvent(QGraphicsSceneMouseEvent *event){ } void DragItem::mouseMoveEvent(QGraphicsSceneMouseEvent *event){ } void DragItem::mousePressEvent(QGraphicsSceneMouseEvent *event){ QMimeData* mime = new QMimeData(); QDrag* drag = new QDrag(event->widget()); drag->setMimeData(mime); drag->exec(); } void DragItem::mouseReleaseEvent(QGraphicsSceneMouseEvent *event){ } main.cpp instantiates a Widget and shows it. When I try to drag the circle, the app just creates another circle over the original one, regardless of where I release the drag. qDebug() in DragScene's dropEvent() shows QPointF(0,0) everytime the drag ends. I'm having a hard time trying to understand exactly what I have to do, which classes I should subclass, which methods needs to be overriden, to make this work. The documentation on this isn't very detailed. I'd like to know how to make this work, and if there's some other, more comprehensive resource to learn about the graphics view framework, besides the official documentation (which is excellent btw, but it would be great if there was a more detailed treatise on the subject). EDIT: Following badgerr's advice, I replaced item-pos() in DragScene::dropEvent() with item-scenePos(), now the drop event creates a new circle in the drop site, which is more or less what I wanted. But the original circle is still in place, and while the drag is in progress, the item doesn't follow the mouse cursor. The QGraphicsSceneDragDropEvent documentation says that pos() should return the cursor position in relation to the view that sent the event, which, unless I got it wrong, shouldn't be (0,0) all the time. Weird. I've read in a forum post that you can use QDrag::setPixMap() to show something during the drag, and in examples I've seen pictures being set as pixmaps, but how do I make the pixmap just like the graphics item I'm supposed to be dragging?

• What add-in/workbench framework is the best .NET alternative to Eclipse RCP?

  - by Winston Fassett

  I'm looking for a plugin-based application framework that is comparable to the Eclipse Plugin Framework, which to my simple mind consists of: a core plugin management framework (Equinox / OSGI), which provides the ability to declare extension endpoints and then discover and load plugins that service those endpoints. (this is different than Dependency Injection, but admittedly the difference is subtle - configuration is highly de-centralized, there are versioning concerns, it might involve an online plugin repository, and most importantly to me, it should be easy for the user to add plugins without needing to know anything about the underlying architecture / config files) many layers of plugins that provide a basic workbench shell with concurrency support, commands, preference sheets, menus, toolbars, key bindings, etc. That is just scratching the surface of the RCP, which itself is meant to serve as the foundation of your application, which you build by writing / assembling even more plugins. Here's what I've gleaned from the internet in the past couple of days... As far as I can tell, there is nothing in the .NET world that remotely approaches the robustness and maturity of the Eclipse RCP for Java but there are several contenders that do either #1 or #2 pretty well. (I should also mention that I have not made a final decision on WinForms vs WPF, so I'm also trying to understand the level of UI coupling in any candidate framework. I'm also wondering about platform coupling and source code licensing) I must say that the open-source stuff is generally less-documented but easier to understand, while the MS stuff typically has more documentation but is less accessible, so that with many of the MS technologies, I'm left wondering what they actually do, in a practical sense. These are the libraries I have found: SharpDevelop The first thing I looked at was SharpDevelop, which does both #1 and also #2 in a basic way (no insult to SharpDevelop, which is admirable - I just mean more basic than Eclipse RCP). However, SharpDevelop is an application more than a framework, and there are basic assumptions and limitations there (i.e. being somewhat coupled to WinForms). Still, there are some articles on CodeProject explaining how to use it as the foundation for an application. System.Addins It appears that System.Addins is meant to provide a robust add-in loading framework, with some sophisticated options for loading assemblies with varying levels of trusts and even running the out of process. It appears to be primarily code-based, and pretty code-heavy, with lots of assemblies that serve to insulate against versioning issues., using Guidance Automation to generate a good deal of code. So far I haven't found many System.AddIns articles that illustrate how it could be used to build something like an Eclipse RCP, and many people seem to be wringing their hands about its complexity. Mono.Addins It appears that Mono.Addins was influenced by System.Addins, SharpDevelop, and MonoDevelop. It seems to provide the basics from System.Addins, with less sophisticated options for plugin loading, but more simplicity, with attribute-based registration, XML manifests, and the infrastructure for online plugin repositories. It has a pretty good FAQ and documentation, as well as a fairly robust set of examples that really help paint a picture of how to develop an architecture like that of SharpDevelop or Eclipse. The examples use GTK for UI, but the framework itself is not coupled to GTK. So it appears to do #1 (add-in loading) pretty well and points the way to #2 (workbench framework). It appears that Mono.Addins was derived from MonoDevelop, but I haven't actually looked at whether MonoDevelop provides a good core workbench framework. Managed Extensibility Framework This is what everyone's talking about at the moment, and it's slowly getting clearer what it does, but I'm still pretty fuzzy, even after reading several posts on SO. The official word is that it "can live side-by-side" with System.Addins. However, it doesn't reference it and it appears to reproduce some of its functionality. It seems to me, then, that it is a simpler, more accessible alternative to System.Addins. It appears to be more like Mono.Addins in that it provides attribute-based wiring. It provides "catalogs" that can be attribute-based or directory-based. It does not seem to provide any XML or manifest-based wiring. So far I haven't found much documentation and the examples seem to be kind of "magical" and more reminiscent of attribute-based DI, despite the clarifications that MEF is not a DI container. Its license just got opened up, but it does reference WindowsBase -- not sure if that means it's coupled to Windows. Acropolis I'm not sure what this is. Is it MEF, or something that is still coming? Composite Application Blocks There are WPF and Winforms Composite Application blocks that seem to provide much more of a workbench framework. I have very little experience with these but they appear to rely on Guidance Automation quite a bit are obviously coupled with the UI layers. There are a few examples of combining MEF with these application blocks. I've done the best I could to answer my own question here, but I'm really only scratching the surface, and I don't have experience with any of these frameworks. Hopefully some of you can add more detail about the frameworks you have experience with. It would be great if we could end up with some sort of comparison matrix.

• Podcast: The Invisible UI : Natural User Interfaces with Josh Blake

  - by craigshoemaker

  Josh Blake of Infostrat joins Pixel8 to discuss NUI development in .NET. Josh is the author of the upcoming book Multitouch on Windows from Manning. Reaching far beyond theory and the niche market of Microsoft Surface, NUI development is now possible with Silverlight and WPF development on Windows 7 and Windows 7 Mobile devices. Subscribe to the podcast! The Natural User Interface (NUI) was a prominent force at MIX10. What is NUI? Wikipedia defines it as: Natural user interface, or NUI, is the common parlance used by designers and developers of computer interfaces to refer to a user interface that is effectively invisible, or becomes invisible with successive learned interactions, to its users. The word natural is used because most computer interfaces use artificial control devices whose operation has to be learned. A NUI relies on a user being able to carry out relatively natural motions, movements or gestures that they quickly discover control the computer application or manipulate the on-screen content. The most descriptive identifier of a NUI is the lack of a physical keyboard and/or mouse. In our interview Josh demystifies what NUI is, makes a distinction between gestures and manipulations, and talks about what is possible today for NUI development. For more from Josh make sure to check out his book: and watch his MIX Presentation: Developing Natural User Interfaces with Microsoft Silverlight and WPF 4 Touch Resources Mentioned in the Show Check out the following videos that show the roots and future of NUI development: Jeff Han's Multi-Touch TED Presentation Microsoft Surface Project Natal MIX10 Day 2 Keynote A few times during our talk Bill Buxton’s work is mentioned.

• AutoVue Integrates with Primavera P6

  - by celine.beck

  Oracle's Primavera P6 Enterprise Project Portfolio Management is an integrated project portfolio management (PPM) application that helps select the right strategic mix of projects, balance resource capacity, manage project risk and complete projects on time and within budget. AutoVue 19.3 and later versions (release 20.0) now integrate out of the box with the Web version of Oracle Primavera P6 release 7. The integration between the two products, which was announced during Oracle Open World 2009, provides project teams with ready access to any project documents directly from within the context of P6 in support for project scope definition and project planning and execution. You can learn more about the integration between AutoVue and Primavera P6 by: Listening to the Oracle Appcast entitled Enhance Primavera Project Document Collaboration with AutoVue Enterprise Visualization Watching an Oracle Webcast about how to improve project success with document visualization and collaboration Watching a recorded demo of the integrated solution Teams involved in complex projects like construction or plant shutdown activities are highly interdependent: the decisions of one affecting the actions of many others. This coupled with increasing project complexity, a vast array of players and heavy engineering and document-intensive workflows makes it more challenging to complete jobs on time and within budget. Organizations need complete visibility into project information, as well as robust project planning, risk analysis and resource balancing capabilities similar to those featured in Primavera P6 ; they also need to make sure that all project stakeholders, even those who neither understand engineering drawings nor are interested in engineering details that go beyond their specific needs, have ready access to technically advanced project information. This is exactly what the integration between AutoVue and Primavera delivers: ready access to any project information attached to Primavera projects, tasks or activities via AutoVue. There is no need for users to waste time searching for project-related documents or disrupting engineers for printouts, users have all the context they need to make sound decisions right from within Primavera P6 with a single click of a button. We are very excited about this new integration. If you are using Primavera and / or Primavera tied with AutoVue, we would be interested in getting your feedback on this integration! Please do not hesitate to post your comments / reactions on the blog!

• Back to Basics: When does a .NET Assembly Dependency get loaded

  - by Rick Strahl

  When we work on typical day to day applications, it's easy to forget some of the core features of the .NET framework. For me personally it's been a long time since I've learned about some of the underlying CLR system level services even though I rely on them on a daily basis. I often think only about high level application constructs and/or high level framework functionality, but the low level stuff is often just taken for granted. Over the last week at DevConnections I had all sorts of low level discussions with other developers about the inner workings of this or that technology (especially in light of my Low Level ASP.NET Architecture talk and the Razor Hosting talk). One topic that came up a couple of times and ended up a point of confusion even amongst some seasoned developers (including some folks from Microsoft <snicker>) is when assemblies actually load into a .NET process. There are a number of different ways that assemblies are loaded in .NET. When you create a typical project assemblies usually come from: The Assembly reference list of the top level 'executable' project The Assembly references of referenced projects Dynamically loaded at runtime via AppDomain/Reflection loading In addition .NET automatically loads mscorlib (most of the System namespace) the boot process that hosts the .NET runtime in EXE apps, or some other kind of runtime hosting environment (runtime hosting in servers like IIS, SQL Server or COM Interop). In hosting environments the runtime host may also pre-load a bunch of assemblies on its own (for example the ASP.NET host requires all sorts of assemblies just to run itself, before ever routing into your user specific code). Assembly Loading The most obvious source of loaded assemblies is the top level application's assembly reference list. You can add assembly references to a top level application and those assembly references are then available to the application. In a nutshell, referenced assemblies are not immediately loaded - they are loaded on the fly as needed. So regardless of whether you have an assembly reference in a top level project, or a dependent assembly assemblies typically load on an as needed basis, unless explicitly loaded by user code. The same is true of dependent assemblies. To check this out I ran a simple test: I have a utility assembly Westwind.Utilities which is a general purpose library that can work in any type of project. Due to a couple of small requirements for encoding and a logging piece that allows logging Web content (dependency on HttpContext.Current) this utility library has a dependency on System.Web. Now System.Web is a pretty large assembly and generally you'd want to avoid adding it to a non-Web project if it can be helped. So I created a Console Application that loads my utility library: You can see that the top level Console app a reference to Westwind.Utilities and System.Data (beyond the core .NET libs). The Westwind.Utilities project on the other hand has quite a few dependencies including System.Web. I then add a main program that accesses only a simple utillity method in the Westwind.Utilities library that doesn't require any of the classes that access System.Web: static void Main(string[] args) { Console.WriteLine(StringUtils.NewStringId()); Console.ReadLine(); } StringUtils.NewStringId() calls into Westwind.Utilities, but it doesn't rely on System.Web. Any guesses what the assembly list looks like when I stop the code on the ReadLine() command? I'll wait here while you think about it… … … So, when I stop on ReadLine() and then fire up Process Explorer and check the assembly list I get: We can see here that .NET has not actually loaded any of the dependencies of the Westwind.Utilities assembly. Also not loaded is the top level System.Data reference even though it's in the dependent assembly list of the top level project. Since this particular function I called only uses core System functionality (contained in mscorlib) there's in fact nothing else loaded beyond the main application and my Westwind.Utilities assembly that contains the method accessed. None of the dependencies of Westwind.Utilities loaded. If you were to open the assembly in a disassembler like Reflector or ILSpy, you would however see all the compiled in dependencies. The referenced assemblies are in the dependency list and they are loadable, but they are not immediately loaded by the application. In other words the C# compiler and .NET linker are smart enough to figure out the dependencies based on the code that actually is referenced from your application and any dependencies cascading down into the dependencies from your top level application into the referenced assemblies. In the example above the usage requirement is pretty obvious since I'm only calling a single static method and then exiting the app, but in more complex applications these dependency relationships become very complicated - however it's all taken care of by the compiler and linker figuring out what types and members are actually referenced and including only those assemblies that are in fact referenced in your code or required by any of your dependencies. The good news here is: That if you are referencing an assembly that has a dependency on something like System.Web in a few places that are not actually accessed by any of your code or any dependent assembly code that you are calling, that assembly is never loaded into memory! Some Hosting Environments pre-load Assemblies The load behavior can vary however. In Console and desktop applications we have full control over assembly loading so we see the core CLR behavior. However other environments like ASP.NET for example will preload referenced assemblies explicitly as part of the startup process - primarily to minimize load conflicts. Specifically ASP.NET pre-loads all assemblies referenced in the assembly list and the /bin folder. So in Web applications it definitely pays to minimize your top level assemblies if they are not used. Understanding when Assemblies Load To clarify and see it actually happen what I described in the first example , let's look at a couple of other scenarios. To see assemblies loading at runtime in real time lets create a utility function to print out loaded assemblies to the console: public static void PrintAssemblies() { var assemblies = AppDomain.CurrentDomain.GetAssemblies(); foreach (var assembly in assemblies) { Console.WriteLine(assembly.GetName()); } } Now let's look at the first scenario where I have class method that references internally uses System.Web. In the first scenario lets add a method to my main program like this: static void Main(string[] args) { Console.WriteLine(StringUtils.NewStringId()); Console.ReadLine(); PrintAssemblies(); } public static void WebLogEntry() { var entry = new WebLogEntry(); entry.UpdateFromRequest(); Console.WriteLine(entry.QueryString); } UpdateFromWebRequest() internally accesses HttpContext.Current to read some information of the ASP.NET Request object so it clearly needs a reference System.Web to work. In this first example, the method that holds the calling code is never called, but exists as a static method that can potentially be called externally at some point. What do you think will happen here with the assembly loading? Will System.Web load in this example? No - it doesn't. Because the WebLogEntry() method is never called by the mainline application (or anywhere else) System.Web is not loaded. .NET dynamically loads assemblies as code that needs it is called. No code references the WebLogEntry() method and so System.Web is never loaded. Next, let's add the call to this method, which should trigger System.Web to be loaded because a dependency exists. Let's change the code to: static void Main(string[] args) { Console.WriteLine(StringUtils.NewStringId()); Console.WriteLine("--- Before:"); PrintAssemblies(); WebLogEntry(); Console.WriteLine("--- After:"); PrintAssemblies(); Console.ReadLine(); } public static void WebLogEntry() { var entry = new WebLogEntry(); entry.UpdateFromRequest(); Console.WriteLine(entry.QueryString); } Looking at the code now, when do you think System.Web will be loaded? Will the before list include it? Yup System.Web gets loaded, but only after it's actually referenced. In fact, just until before the call to UpdateFromRequest() System.Web is not loaded - it only loads when the method is actually called and requires the reference in the executing code. Moral of the Story So what have we learned - or maybe remembered again? Dependent Assembly References are not pre-loaded when an application starts (by default) Dependent Assemblies that are not referenced by executing code are never loaded Dependent Assemblies are just in time loaded when first referenced in code All of this is nothing new - .NET has always worked like this. But it's good to have a refresher now and then and go through the exercise of seeing it work in action. It's not one of those things we think about everyday, and as I found out last week, I couldn't remember exactly how it worked since it's been so long since I've learned about this. And apparently I'm not the only one as several other people I had discussions with in relation to loaded assemblies also didn't recall exactly what should happen or assumed incorrectly that just having a reference automatically loads the assembly. The moral of the story for me is: Trying at all costs to eliminate an assembly reference from a component is not quite as important as it's often made out to be. For example, the Westwind.Utilities module described above has a logging component, including a Web specific logging entry that supports pulling information from the active HTTP Context. Adding that feature requires a reference to System.Web. Should I worry about this in the scope of this library? Probably not, because if I don't use that one class of nearly a hundred, System.Web never gets pulled into the parent process. IOW, System.Web only loads when I use that specific feature and if I am, well I clearly have to be running in a Web environment anyway to use it realistically. The alternative would be considerably uglier: Pulling out the WebLogEntry class and sticking it into another assembly and breaking up the logging code. In this case - definitely not worth it. So, .NET definitely goes through some pretty nifty optimizations to ensure that it loads only what it needs and in most cases you can just rely on .NET to do the right thing. Sometimes though assembly loading can go wrong (especially when signed and versioned local assemblies are involved), but that's subject for a whole other post…© Rick Strahl, West Wind Technologies, 2005-2012Posted in .NET  CSharp   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• SQLAuthority News – Guest Post – FAULT Contract in WCF with Learning Video

  - by pinaldave

  This is guest post by one of my very good friends and .NET MVP, Dhananjay Kumar. The very first impression one gets when they meet him is his politeness. He is an extremely nice person, but has superlative knowledge in .NET and is truly helpful to all of us. Objective: This article will give a basic introduction on: How to handle Exception at service side? How to use Fault contract at Service side? How to handle Service Exception at client side? A Few Points about Exception at Service Exception is technology-specific. Exception should not be shared beyond service boundary. Since Exception is technology-specific, it cannot be propagated to other clients. Exception is of many types. CLR Exception Windows32 Exception Runtime Exception at service C++ Exception Exception is very much native to the technology in which service is made. Exception must be converted from technology-specific information to natural information that can be communicated to the client. SOAP Fault FaultException<T> Service should throw FaultException<T>, instead of the usual CLR exception. FaultException<T> is a specialization of Fault Exception. Any client that programs against FaultException can handle the Exception thrown by FaultException<T>. The type parameter T conveys the error detail. T can be of any type like Exception, CLR Type or any type that can be serialized. T can be of type Data contract. T is a generic parameter that conveys the error details.

• What Gets Measured Gets Managed

  - by steve.diamond

  OK, so if I were to claim credit for inventing that expression, I guess I could share the mantle with Al Gore, creator of the Internet. But here's the point: How many of us acquire CRM systems without specifically benchmarking several key performance indicators across sales, marketing and service BEFORE and AFTER deployment of said system? Yes, this may sound obvious and it might provoke the, "Well of course, Diamond!" response, but is YOUR company doing this? Can you define in quantitative terms the delta across multiple parameters? I just trolled the Web site of one of my favorite sales consultancy firms, The Alexander Group. Right on their home page is a brief appeal citing the importance of benchmarking. The corresponding landing page states, "The fact that hundreds of sales executives now track how their sales forces spend time means they attach great value to understanding how much time sellers actually devote to selling." The opportunity is to extend this conversation to benchmarking the success that companies derive from the investment they make in CRM systems, i.e., to the automation side of the equation. To a certain extent, the 'game' is analogous to achieving optimal physical fitness. One may never quite get there, but beyond the 95% threshold of "excellence," she/he may be entering the realm of splitting infinitives. But at the very start, and to quote verbiage from the aforementioned Alexander Group Web page, what gets measured gets managed. And getting to that 95% level along several key indicators would be a high quality problem indeed, don't you think? Yes, this could be a "That's so 90's" conversation, but is it really?

• So long and thanks for the fish&hellip;

  - by Geoff N. Hiten

  This marks my last post as a SQLPASS Board member.  I learned a lot during my year of service and I thank everyone involved for this opportunity.  I would especially like to thank the Chapter leaders and Regional Mentors for Virtual Chapters who (mostly) patiently taught me about Virtual Chapters.   I hope the changes I put in place will help strengthen and grow VCs and PASS going forward.  I would also like to thank every one who encouraged me to reach beyond my comfort zone and accept a leadership position within the PASS organization.  My overall principle was to be a good steward of the PASS community.  Could I have done more?  Always. Did I do enough?  I hope so.  But PASS is a volunteer organization and my time, like yours, is limited.  I have other obligations in life that supersede PASS.  Now I have more time for some of those.  I won’t be going away or leaving the SQL Community.  I will still contribute to the community and support PASS, just in a different role.  Time to let somebody else enjoy the hot seat for a while. Finally, everyone who voted (not just for me) deserves a thanks.  More voters and more engaged voters, strong candidates, and a vigorous debate were all I wanted out of declaring as a candidate last year. This year the SQL community got exactly that. Thank you..

• Is it illegal to rewrite every line of an open source project in a slightly different way, and use it in a closed source project?

  - by Chris Barry

  There is some code which is GPL or LGPL that I am considering using for an iPhone project. If I took that code (JavaScript) and rewrote it in a different language for use on the iPhone would that be a legal issue? In theory the process that has happened is that I have gone through each line of the project, learnt what it is doing, and then reimplemented the ideas in a new language. To me it seems this is like learning how to implement something, but then reimplementing it separately from the original licence. Therefore you have only copied the algorithm, which arguably you could have learnt from somewhere else other than the original project. Does the licence cover the specific implementation or the algorithm as well? EDIT------ Really glad to see this topic create a good conversation. To give a bit more backing to the project, the code involved does some kind of audio analysis. I believe it is non-trivial to learn or implement, although I was prepared to embark on this task (I'm at the level where I can implement an FFT algorithm, and this was going to go beyond that.) It is a fairly low LOC script, so I didn't think it would be too hard to do a straight port. I really like the idea of rereleasing my port as well as using it in the application. I don't see any problem with that, and it would be a great way to give something back to the community. I was going to add a line about not wanting to discuss the moral issues, but I'm quite glad I didn't as it seems to have fired the debate a bit. I still feel a bit odd about using open source code to learn from. Does this mean that anything one learns from an open source project is not allowed to be used in a closed source project? And how long after or different does an implementation have to be to not be considered violation of the licence? Murky! EDIT 2 -------- Follow up question

• Don&rsquo;t apply for your first job somewhere; apply for an experience at Oracle.

  - by cristian.condurache(at)oracle.com

  Hi! My name is Stijn and I currently work as a Business Development Consultant for Oracle in Dublin since November 2010. I’m originally from Belgium and I graduated last year from the Vlerick Leuven Gent Management School. In many ways you could say I’m living the life I asked for: an international career with global organization. I’m unbelievably grateful however, because opportunities like this don’t come by the dozen. Actually, going through university and business school my dreams of an international career were clouded quite quickly. Following all the ‘right’ steps wasn’t enough. The lack of offers for, and trust in, new starters to take on a challenge like this was a reality check for me and many of my friends. It takes a company that recognizes the opportunity of recruiting talented individuals by offering them something they actually want: a first job based abroad! My job is focused on generating demand for Oracle products over the phone. In only a few months, the amazing things I’ve experienced, the people I’ve talked to, the learning experiences I’ve had in and outside of work are too many to list. From having CEO’s on the phone, to having meetings with 15 different nationalities, to getting settled from scratch in a new country… it’s something that builds you as a person. But don’t be fooled though, it’s on you - where it starts. Although Oracle gives you the best training and resources to do your job and Ireland is a playground for everything else, it’s you that is responsible. You are in control and much is expected. What you get in return however, is beyond incredible. If you are interested in joining the same team as Stijn, please visit http://campus.oracle.com or contact [email protected] Technorati Tags: Oracle,opportunity,global organisation,career,Business Development Consultant

• BUILD apps that use C++ AMP

  - by Daniel Moth

  If you are a developer on the Microsoft platform, you are hopefully attending (live or virtually) the sessions of the BUILD conference, aka //build/ in Anaheim, CA. The conference sold out not long after it opened registration, and it achieved that without sharing *any* session details nor a meaningful agenda up until after the keynote today – impressive! I am speaking at BUILD and hope you'll catch my talk at 9am on Friday (the last day of the conference) at Marriott Elite 2 Ballroom. Session details follow. 802 - Taming GPU compute with C++ AMP Developers today inject parallelism into their compute-intensive applications in order to take advantage of multi-core CPU hardware. Beyond CPUs, however, compute accelerators such as general-purpose GPUs can provide orders of magnitude speed-ups for data parallel algorithms. How can you as a C++ developer fully utilize this heterogeneous hardware from your Visual Studio environment?  How can you benefit from this tremendous performance boost in your Visual C++ solutions without sacrificing developer productivity?  The answers will be presented in this session about C++ Accelerated Massive Parallelism. I'll be covering a lot of the material I've been recently blogging about on my blog that you are reading, which I have also indexed over on our team blog under the title: "C++ AMP in a nutshell". Comments about this post by Daniel Moth welcome at the original blog.

• Drupal CMS most Stable for High Traffic

  - by Aditi

  Drupal users have high satisfaction with Drupal compared to the Joomla users, for a number of reasons. If you are thinking of  choosing a high performance platform to run your high traffic website.. Drupal Installation is your forte! Overload Scenario Drupal is scalable high performance CMS and is stable under heavy load. If your server is pushed beyond its capacity, Drupal shuts off gracefully and doesn’t crash. As soon as the server is back within its traffic capability, Drupal handles all requests smoothly again. For example if your dedicated server can handle a maximum of 50,000 visits a day, and on lucky days when your news created the buzz in social media and your traffic rose to 70,000 on one day, then your server will be overloaded and usually it crashes causing permanent damage to your database at times.. But if you have used Drupal CMS it closes down gracefully an as soon as traffic goes down to within the server’s capacity, the Drupal running site accepts all requests again. Extensibility Drupal users know that their add-ons integrate better with the core, and their framework makes it easier to extend their CMS’s capabilities.. which makes an extended version of it quite stable unlike Joomla, which loses its strength if you have plenty of plugins & heavy customizations running. Any CMS with number of plugins makes the content complex and reduces your ability to handle high traffic requests. Accessibility Management or ACL Chances are if you are high traffic website, you may have various users & content contributors. ACL means group roles that is assigning people out of the various registered user levels and allocating many kinds of privileges. The most common example is the ability to see or edit a section or selected pages. This efficient feature of Drupal makes it a class apart than other CMSs out there.
