  • Ubuntu cannot resolve unmet dependency

    - by DisgruntledGoat
    I'm trying to install a package on my Ubuntu 8.10 server. However, I get this message: The following packages have unmet dependencies. webmin: Depends: apt-show-versions but it is not going to be installed E: Unmet dependencies. Try ‘apt-get -f install’ with no packages (or specify a solution). So I run apt-get -f install which offers to install apt-show-versions and libapt-pkg-perl.

  • Spring 3 DI using generic DAO interface

    - by Peders
    I'm trying to use @Autowired annotation with my generic Dao interface like this: public interface DaoContainer<E extends DomainObject> { public int numberOfItems(); // Other methods omitted for brevity } I use this interface in my Controller in following fashion: @Configurable public class HelloWorld { @Autowired private DaoContainer<Notification> notificationContainer; @Autowired private DaoContainer<User> userContainer; // Implementation omitted for brevity } I've configured my application context with following configuration <context:spring-configured /> <context:component-scan base-package="com.organization.sample"> <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation" /> </context:component-scan> <tx:annotation-driven /> This works only partially, since Spring creates and injects only one instance of my DaoContainer, namely DaoContainer. In other words, if I ask userContainer.numberOfItems(); I get the number of notificationContainer.numberOfItems() I've tried to use strongly typed interfaces to mark the correct implementation like this: public interface NotificationContainer extends DaoContainer<Notification> { } public interface UserContainer extends DaoContainer<User> { } And then used these interfaces like this: @Configurable public class HelloWorld { @Autowired private NotificationContainer notificationContainer; @Autowired private UserContainer userContainer; // Implementation omitted... } Sadly this fails to BeanCreationException: org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.organization.sample.dao.NotificationContainer com.organization.sample.HelloWorld.notificationContainer; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.organization.sample.NotificationContainer] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} Now, I'm a little confused how should I proceed or is using multiple Dao's even possible. Any help would be greatly appreciated :)

  • Handling dependencies with IoC that change within a single function call

    - by Jess
    We are trying to figure out how to setup Dependency Injection for situations where service classes can have different dependencies based on how they are used. In our specific case, we have a web app where 95% of the time the connection string is the same for the entire Request (this is a web application), but sometimes it can change. For example, we might have 2 classes with the following dependencies (simplified version - service actually has 4 dependencies): public LoginService (IUserRepository userRep) { } public UserRepository (IContext dbContext) { } In our IoC container, most of our dependencies are auto-wired except the Context for which I have something like this (not actual code, it's from memory ... this is StructureMap): x.ForRequestedType().Use() .WithCtorArg("connectionString").EqualTo(Session["ConnString"]); For 95% of our web application, this works perfectly. However, we have some admin-type functions that must operate across thousands of databases (one per client). Basically, we'd want to do this: public CreateUserList(IList<string> connStrings) { foreach (connString in connStrings) { //first create dependency graph using new connection string ???? //then call service method on new database _loginService.GetReportDataForAllUsers(); } } My question is: How do we create that new dependency graph for each time through the loop, while maintaining something that can easily be tested?

  • Embedding Perl Interpreter

    - by cam
    Hi, just downloaded ActivePerl. I want to embed the perl interpreter in a C# application (or at least call the perl interpreter from C#). I need to be able to send send out data to Perl from C#, then receive the output back into C#. I just installed ActivePerl, and added MS Script Control 1.0 as a reference. I found this code on the internet, but am having trouble getting it to work. MSScriptControl.ScriptControlClass Interpreter = new MSScriptControl.ScriptControlClass(); Interpreter.Language = @"ActivePerl"; string Program = @"reverse 'abcde'"; string Results = (string)Interpreter.Eval(Program); return Results; Originally, it had 'PerlScript' instead of 'ActivePerl', but neither work for me. I'm not entirely sure what Interpreter.Language expects. Does it require the path to the interpreter? Solved... I'm not sure how, but when I changed it back to PerlScript it works now. Still, I would like to know if MSScript Control is using ActivePerl or another interpreter.

  • Delay before playing embedded mp3 in Actionscript / Flex 3

    - by lacker
    I am embedding an mp3 into my Flex project for use as a sound effect, but I am finding that every time I play it, there is a delay of about half a second from when I call .play() to when you can hear the sound. This makes it weird because I want the sound effects to sync to game events. My mp3 itself is only about a fifth of a second long so it isn't because of the contents of the mp3. I'm embedding with [Embed(source="assets/Tock.mp3")] [Bindable] public static var TockSound:Class; public var tock_sound:SoundAsset; and then playing with if (tock_sound == null) { tock_sound = new TockSound() as SoundAsset; } Alert.show("tock"); tock_sound.play(); I know there's a delay because the sound plays about a half second after the Alert displays. I did consider that maybe it was the initial loading time of constructing the TockSound, but the delay is there on all the subsequent calls as well. How can I avoid this delay on playing a sound? Update: It turns out this delay is only present when playing the swf on Linux. I believe it is a Linux-specific flaw in Adobe's flash player.

  • Decoupling the view, presentation and ASP.NET Web Forms

    - by John Leidegren
    I have an ASP.NET Web Forms page which the presenter needs to populate with controls. This interaction is somewhat sensitive to the page-life cycle and I was wondering if there's a trick to it, that I don't know about. I wanna be practical about the whole thing but not compromise testability. Currently I have this: public interface ISomeContract { void InstantiateIn(System.Web.UI.Control container); } This contract has a dependency on System.Web.UI.Control and I need that to be able to do things with the ASP.NET Web Forms programming model. But neither the view nor the presenter may have knowledge about ASP.NET server controls. How do I get around this? How can I work with the ASP.NET Web Forms programming model in my concrete views without taking a System.Web.UI.Control dependency in my contract assemblies? To clarify things a bit, this type of interface is all about UI composition (using MEF). It's known through-out the framework but it's really only called from within the concrete view. The concrete view is still the only thing that knows about ASP.NET Web Forms. However those public methods that say InstantiateIn(System.Web.UI.Control) exists in my contract assemblies and that implies a dependency on ASP.NET Web Forms. I've been thinking about some double dispatch mechanism or even visitor pattern to try and work around this.

  • WPF RadioButton selected in UI, but seen by code as IsChecked == false

    - by Mike
    I have some radio buttons in a group box. I select the buttons randomly, and all works perfectly from a visual standpoint and also the event handler is called each time a new button is selected. Now I have a dependency property with a callback when the value changes. When in this callback procedure I read the IsChecked value of any button, the value is False, in spite the button is visually selected (they are all false at the same time, strange). The debugger also displays all buttons unchecked. Hu hu, I'm lacking ideas about the reason, after the basic verifications... <GroupBox> <StackPanel> <RadioButton x:Name="btNone" Content="Disconnected" IsChecked="True" Checked="OnSelChecked"/> <RadioButton x:Name="btManual" Content="Manual" Checked="OnSelChecked"/> </StackPanel> </GroupBox> Event handler: private void OnSelChecked(object sender, RoutedEventArgs e) { if (btManual.IsChecked == true) { // is called } } Dependency property: public static readonly DependencyProperty ManualProperty = DependencyProperty.Register("Manual", typeof(Position), typeof(SwitchBox), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.AffectsRender, new PropertyChangedCallback(OnManualChanged))); Dependency property callback: private static void OnManualChanged(DependencyObject sender, DependencyPropertyChangedEventArgs args) { SwitchBox box = sender as SwitchBox; if (box.btManual.IsChecked == true) { // never true, why?? } }

  • How to collect and inject all beans of a given type in Spring XML configuration

    - by GrzegorzOledzki
    One of the strongest accents of the Spring framework is the Dependency Injection concept. I understand one of the advices behind that is to separate general high-level mechanism from low-level details (as announced by Dependency Inversion Principle). Technically, that boils down to having a bean implementation to know as little as possible about a bean being injected as a dependency, e.g. public class PrintOutBean { private LogicBean logicBean; public void action() { System.out.println(logicBean.humanReadableDetails()); } //... } <bean class="PrintOutBean"> <property name="loginBean" ref="ShoppingCartBean"/> </bean> But what if I wanted to a have a high-level mechanism operating on multiple dependent beans? public class MenuManagementBean { private Collection<Option> options; public void printOut() { for (Option option:options) { // do something for option } //... } } I know one solution would be to use @Autowired annotation in the singleton bean, that is... @Autowired private Collection<Option> options; But doesn't it violate the separation principle? Why do I have to specify what dependents to take in the very same place I use them (i.e. MenuManagementBean class in my example)? Is there a way to inject collections of beans in the XML configuration like this (without any annotation in the MMB class)? <bean class="MenuManagementBean"> <property name="options"> <xxx:autowire by-type="MyOptionImpl"/> </property> </bean>

  • Embedded scripting engine in .Net app

    - by Nate
    I am looking to replace an old control being used for scripting an application. The control used to be called SAX Basic, but is now called WinWrap. It provides us with two primary functions. 1) It's a scripting engine (VB) 2) It has a GUI for developing and debugging scripts that get run in the hosting application. The first feature it provides is actually pretty easy to replace. There are so many great methods of running just about any kind of code at runtime that it's almost a non-issue. Just about any language targeting the .Net runtime will work for us. We've looked at running C#, PowerShell, VB.Net, IronPython, etc. I've also taken a brief look at Lua and F#, but honestly the language isn't the biggest barrier here. Now, for the hard part that seems to keep getting me stuck. We want a code editor, and debugger. Something simple, not unlike PowerShell's ISE would be fine. Just as long as a file could be created, saved, debugged and executed. I'm currently looking into Visual Studio 2010 Shell (Isolated) and I'm also looking at the feasibility of embedding PowerShell ISE in my application. Are there any other editor's I could embed/use in my application? Purchasing a product is not out of the question. It comes down to a combination of ease of use, how well it meets our needs, and how simple deployment and licensing is for developers. Thanks for the pointers

  • How can I change the language of dynamic text in a SWF using flashvars?

    - by Cormac
    I have a SWF with text embedded from an external .txt file. Is there a way I can have a different file used as the text source through the embedcode (swfObject) depending on the language? Here is my current actionscript: myData = new LoadVars(); myData.onLoad = function() { text_clips.project_title.text = this.projecttitle1; }; myData.load("translatetext.txt"); var loader:MovieClipLoader = new MovieClipLoader(); loader.loadClip(_level0.projectimage1,pic1.image_holder); This is the content of translatetext.txt: projecttitle1=This is my translatable text This is the embed code I'm using: <div> <object width="960" height="275" id="rvFlashcontent"> <param name="movie" value="lang_test_3.swf" /> <param name="wmode" value="transparent" /> <param name="flashvars" value="projectimage1=flashimages/testimage.jpg" /> <!--[if !IE]>--> <object type="application/x-shockwave-flash" data="lang_test_3.swf" width="960" height="275"> <param name="wmode" value="transparent" /> <param name="flashvars" value="projectimage1=flashimages/testimage.jpg" /> <!--<![endif]--> <h1>Alt Content</h1> <!--[if !IE]>--> </object> <!--<![endif]--> </object> </div> What I want to do is add a Flashvars parameter to name the file to load, so I can change the language: <param name="flashvars" value="projectimage1=flashimages/image.jpg&projecttext=textfrench.txt" /> There are four languages needed so far, but this will grow so it needs to be flexible enough to let the developers add languages without getting a new SWF each time. Thanks in advance all!

  • Ninject.Web.PageBase still resulting in null reference to injected dependency

    - by Ted
    I have an ASP.NET 3.5 WebForms application using Ninject 2.0. However, attempting to use the Ninject.Web extension to provide injection into System.Web.UI.Page, I'm getting a null reference to my injected dependency even though if I switch to using a service locator to provide the reference (using Ninject), there's no issue. My configuration (dumbed down for simplicity): public partial class Default : PageBase // which is Ninject.Web.PageBase { [Inject] public IClubRepository Repository { get; set; } protected void Page_Load(object sender, EventArgs e) { var something = Repository.GetById(1); // results in null reference exception. } } ... //global.asax.cs public class Global : Ninject.Web.NinjectHttpApplication { /// <summary> /// Creates a Ninject kernel that will be used to inject objects. /// </summary> /// <returns> /// The created kernel. /// </returns> protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(new MyModule()); return kernel; } .. ... public class MyModule : NinjectModule { public override void Load() { Bind<IClubRepository>().To<ClubRepository>(); //... } } Getting the IClubRepository concrete instance via a service locator works fine (uses same "MyModule"). I.e. private readonly IClubRepository _repository = Core.Infrastructure.IoC.TypeResolver.Get<IClubRepository>(); What am I missing? [Update] Finally got back to this, and it works in Classic Pipeline mode, but not Integrated. Is the classic pipeline a requirement? [Update 2] Wiring up my OnePerRequestModule was the problem (which had removed in above example for clarity): protected override IKernel CreateKernel() { var module = new OnePerRequestModule(); module.Init(this); IKernel kernel = new StandardKernel(new MyModule()); return kernel; } ...needs to be: protected override IKernel CreateKernel() { IKernel kernel = new StandardKernel(new MyModule()); var module = new OnePerRequestModule(); module.Init(this); return kernel; } Thus explaining why I was getting a null reference exception under integrated pipeline (to a Ninject injected dependency, or just a page load for a page inheriting from Ninject.Web.PageBase - whatever came first).

  • Is there dependency generation flag for MSVC like gcc's -M

    - by Artyom
    Hello, Is there dependency generation flag for MSVC like gcc's -M flag. Every C++ compiler I have ever used had this kind of flag. How can I create dependencies automatically with MSVC cl compiler. I'm interested for only latest compiler versions i.e. MSVC9 or later but if it works with MSVC8 it is fine as well. If there is built-in external tool to do this (I mean, not cl), it would be fine as well

  • mysql circular dependency in foreign key constraints

    - by Flavius
    Given the schema: What I need is having every user_identities.belongs_to reference an users.id. At the same time, every users has a primary_identity as shown in the picture. However when I try to add this reference with ON DELETE NO ACTION ON UPDATE NO ACTION, MySQL says #1452 - Cannot add or update a child row: a foreign key constraint fails (yap.#sql-a3b_1bf, CONSTRAINT #sql-a3b_1bf_ibfk_1 FOREIGN KEY (belongs_to) REFERENCES users (id) ON DELETE NO ACTION ON UPDATE NO ACTION) I suspect this is due to the circular dependency, but how could I solve it (and maintain referential integrity)?

  • Is possible to make mt.exe embed manifest files correctly in Visual Studio 2008?

    - by Sorin Sbarnea
    I found that mt.exe fails to correctly create and embed manifest files into executables when run inside a VCPROJ. For example the same executable load well on Windows 7 but failed to load on Windows XP. The manifest was embedded and correct. After I spend lots of hours searching for possible reasons and solution I modified the project settings to generate the manifest outside the exe file. Now it works on both systems. Here are the examples for debug builds. With embed disabled: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel> </requestedPrivileges> </security> </trustInfo> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.DebugCRT" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.DebugMFC" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b"></assemblyIdentity> </dependentAssembly> </dependency> </assembly> This is with embed enabled: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <trustInfo xmlns="urn:schemas-microsoft-com:asm.v3"> <security> <requestedPrivileges> <requestedExecutionLevel level="asInvoker" uiAccess="false" /> </requestedPrivileges> </security> </trustInfo> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.DebugCRT" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b" /> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.VC90.DebugMFC" version="9.0.21022.8" processorArchitecture="x86" publicKeyToken="1fc8b3b9a1e18e3b" /> </dependentAssembly> </dependency> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="6.0.0.0" processorArchitecture="x86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> </assembly> If you compare them the second one adds common controls (I don't know from where) and also it is a small difference with the syntax of requestedExecutionLevel tag.

  • How can I neatly embed Flash in a page in a way that is cross-browser compatible?

    - by Mark Hatton
    When I receive Flash objects from my designer, it comes with an example HTML page which includes both <object> tags and <embed> tags as well as a whole heap of JavaScript. If I copy and paste this code in to my webpage, it works, but the code looks a mess (and there is so much of it!). If I remove the extra code and try either just <embed> or <object> on their own, it works in some browsers, but not others. Is there a neat, minimal method that works in all the major browsers?
