  • what possible workarounds are there for "only parameterless constructors are support in Linq to Enti

    - by Ralph Shillington
    In my query I need to return instances of a class that doesn't have a default constructor (specifically this is in a custom Membership provider, and MembershipUser is the culprit) var users = from l in context.Logins select new MembershipUser( Name, l.Username, // username l.Id, // provider key l.MailTo, l.PasswordQuestion, l.Notes.FirstOrDefault().NoteText, l.IsApproved, l.IsLockedOut, l.CreatedOn, l.LastLoginOn.HasValue ? l.LastLoginOn.Value : DateTime.MinValue, l.LastActivityOn.HasValue ? l.LastActivityOn.Value : DateTime.MinValue, DateTime.MinValue, l.LastLockedOutOn.HasValue ? l.LastLockedOutOn.Value : DateTime.MinValue ); is syntacitally correct, but results in a runtime error as Only parameterless constructors and initializers are supported in LINQ to Entities.

  • Jquery Accordion and Fading

    - by Slick Willis
    I am trying to create a jquery accordion that fades the header of the accordion out when the page is loaded then fades it in when the mouse hovers. The accordion also opens when the mouse hovers. I am able to get all of this working, the problem I am having is when the accordion opens the header moves away and the mouse is no longer on it to keep it lit. I would like the links to keep the header lit as well as if the mouse is on the header itself. Below is the code that I wrote for it. <html> <head <script type='text/javascript' src='http://accidentalwords.squarespace.com/storage/jquery/jquery-1.4.2.min.js'></script> <script type='text/javascript' src='http://accidentalwords.squarespace.com/storage/jquery/jquery-custom-181/jquery-ui-1.8.1.custom.min.js'></script> </head> <body bgcolor="black"> <style = "css/text"> .links { font-family: "Georgia", "Verdana", serif; line-height: 30px; margin-left: 20px; margin-top: 5px; } .Title { font-family: "Geneva", "Verdana", serif; font-weight: bold; font-size: 2em; text-align: left; font-variant: small-caps; border-bottom: solid 2px #25FF00; padding-bottom:5px; margin-bottom: 10px; } </style> <script type="text/javascript"> $(document).ready(function(){ $(".Title").fadeTo(1,0.25); $(".Title").hover(function () { $(this).stop().fadeTo(250,1) .closest(".Title").find(".links").fadeTo(250,0.75); }, function() { $(this).stop().fadeTo(250,0.25); }); }); $(function() { $("#accordion").accordion({ event: "mouseover" }); }); </script> <p>&nbsp</p> <div id="accordion"> <div class="Title"><a href="#"STYLE="TEXT-DECORATION: NONE; color: #25FF00;">Reference</a></div> <div class="links"> <a href="http://docs.jquery.com/Main_Page" STYLE="TEXT-DECORATION: NONE; color: #25FF00;">Jquery Documentation/Help</a><br> <a href="http://stackoverflow.com/" STYLE="TEXT-DECORATION: NONE; color: #25FF00;">Stack Overflow</a><br> <a href="http://www.w3schools.com/" STYLE="TEXT-DECORATION: NONE; color: #25FF00;">w3schools.com</a><br> </div> <div class="Title"><a href="#"STYLE="TEXT-DECORATION: NONE; color: #FF7200;">Gaming</a></div> <div class="links"> <a href="http://docs.jquery.com/Main_Page" STYLE="TEXT-DECORATION: NONE; color: #FF7200;">Jquery Documentation/Help</a><br> <a href="http://stackoverflow.com/" STYLE="TEXT-DECORATION: NONE; color: #FF7200;">Stack Overflow</a><br> <a href="http://www.w3schools.com/" STYLE="TEXT-DECORATION: NONE; color: #FF7200;">w3schools.com</a><br></div> <div class="Title"><a href="#"STYLE="TEXT-DECORATION: NONE; color: #00DEFF;">Grub</a></div> <div class="links"> <a href="http://docs.jquery.com/Main_Page" STYLE="TEXT-DECORATION: NONE; color: #00DEFF;">Jquery Documentation/Help</a><br> <a href="http://stackoverflow.com/" STYLE="TEXT-DECORATION: NONE; color: #00DEFF;">Stack Overflow</a><br> <a href="http://www.w3schools.com/" STYLE="TEXT-DECORATION: NONE; color: #00DEFF;">w3schools.com</a><br> </div> <div class="Title"><a href="#"STYLE="TEXT-DECORATION: NONE; color: #F8FF00;">Drinks</a></div> <div class="links"> <a href="http://docs.jquery.com/Main_Page" STYLE="TEXT-DECORATION: NONE; color: #F9FF00;">Jquery Documentation/Help</a><br> <a href="http://stackoverflow.com/" STYLE="TEXT-DECORATION: NONE; color: #F8FF00;">Stack Overflow</a><br> <a href="http://www.w3schools.com/" STYLE="TEXT-DECORATION: NONE; color: #F8FF00;">w3schools.com</a><br> </div> </div> </body> </html>

  • Grails 1.2.1 with Spring 3.0.0 dependency problem under Jetty

    - by archer
    Just moved to Grails 1.2.1 (used 1.1.1 before). Changed application.properties, ran grails upgrade, fixed BuildConfig and Bootstrap - everything works just fine from grails console. However, getting a problem when deploy packaged war under jetty 6.1.22: 1581 [main] ERROR org.springframework.web.context.ContextLoader - Context initialization failed org.springframework.beans.factory.access.BootstrapException: Error executing bootstraps; nested exception is java.lang.NoSuchMethodError: org.codehaus.groovy.grails.commons.spring.ReloadAwareAutowireCapableBeanFactory.setParameterNameDiscoverer(Lorg/springframework/core/ParameterNameDiscoverer;)V My project is built with maven2. I researched the war dependencies and see that both spring 2.5.6 and 3.0.0.RELEASE are used there. I then tried to suppress use of spring 2.5.6 and got a problem with Acegi plugin (using version 0.5.1): 2010-03-10 21:06:56.440:WARN::Nested in org.springframework.beans.factory.access.BootstrapException: Error executing bootstraps; nested exception is java.lang.NoSuchMethodError: org.springframework.web.context.ConfigurableWebApplicationContext.setId(Ljava/lang/String;)V Any help would be greatly appreciated.

  • How to customize pickle for django model objects

    - by muudscope
    I need to pickle a complex object that refers to django model objects. The standard pickling process stores a denormalized object in the pickle. So if the object changes on the database between pickling and unpickling, the model is now out of date. (I know this is true with in-memory objects too, but the pickling is a convenient time to address it.) So what I'd like is a way to not pickle the full django model object. Instead just store its class and id, and re-fetch the contents from the database on load. Can I specify a custom pickle method for this class? I'm happy to write a wrapper class around the django model to handle the lazy fetching from db, if there's a way to do the pickling.

  • Overload method (specifically drawRect:) without subclassing.

    - by SooDesuNe
    I'm using a container UIView to house a UIImageView and do some custom drawing. At this point I'd like to do some drawing on top of my subview. So overriding drawRect: in my container UIView will only draw below the subviews. Is there a way to overload drawRect: in my subview without subclassing it? I think method swizzling may be the answer, but I'm hoping not. (NOTE: yes, it would have been smarter to have the UIView be the subview of the UIImageView, but unfortunately I'm committed to my mistake now.)

  • Defining a SPI in Clojure

    - by Joe Holloway
    I'm looking for an idiomatic way(s) to define an interface in Clojure that can be implemented by an external "service provider". My application would locate and instantiate the service provider module at runtime and delegate certain responsibilities to it. Let's say, for example, that I'm implementing a RPC mechanism and I want to allow a custom middleware to be injected at configuration time. This middleware could pre-process the message, discard messages, wrap the message handler with logging, etc. I know several ways to do this if I fall back to Java reflection, but feel that implementing it in Clojure would help my understanding. (Note, I'm using SPI in a general sense here, not specifically referring to the way it's defined in the JAR file specification) Thanks

  • Declaring CustomViewController?

    - by fuzzygoat
    I have noticed in some of my older apps that in situations where I have added a custom View Controller I have not changed the View Controller class in the application delegate. For example, below I have created a CustomViewController class but have declared viewController as UIViewController. @interface ApplicationAppDelegate: NSObject <UIApplicationDelegate> { UIWindow *window; UIViewController *viewController; } My question is, both work, but for correctness should I be writing this as follows: @class CustomViewController; @interface ApplicationAppDelegate: NSObject <UIApplicationDelegate> { UIWindow *window; CustomViewController *viewController; } gary

  • Code to apply expression tree directly to List

    - by Gamma Vega
    Is there a method call in Linq that will apply a expression tree directly on a List<V>? For instance, if I have a expression tree that is built on Order type, and i have a collection of List<Order> items on which i need to apply this expression. I am looking something similar to: class OrderListStore : IQueryable<V>, <other interfaces required to implement custom linq provider> { List<Order> orders; public Expression Expression { get { return Expression.Constant(this); } } IEnumerator<V> IEnumerable<V>.GetEnumerator() { //Here I need to have a method that will take the existing expression //and directly apply on list something like this .. Expression.Translate(orders); } } Any help in this regard is highly appreciated.

  • How to make a structure map powered viewengine in asp.net mvc

    - by Andrew Bullock
    My views extend a base view class ive made: public class BaseView : ViewPage At the moment im calling ObjectFactory.GetInstance inside this class' constructor to get some interface implementations but id like to use structuremap to inject them as constructor arguments. Im using a structuremapcontrollerfactory to create my controllers, but how can i do the same for views? I know i can implement a custom ViewEngine, but using reflector to look at the mvc default viewengine and its dependencies, it seems to go on and on and i'd rather not have to re-implement stuff thats already there. Has anyone got a cunning idea how to solve this? I know i could make things easier with setter instead of constructor injection but id rather avoid that if possible.

  • How can a Delphi TForm / TPersistent object calculate its own construction and deserialization time?

    - by mjustin
    For performance tests I need a way to measure the time needed for a form to load its definition from the DFM. All existing forms inherit a custom form class. To capture the current time, this base class needs overriden methods as "extension points": start of the deserialization process after the deserialization (can be implemented by overriding the Loaded procedure) the moment just before the execution of the OnFormCreate event So the log for TMyForm.Create(nil) could look like: - 00.000 instance created - 00.010 before deserialization - 01.823 after deserialization - 02.340 before OnFormCreate Which TObject (or TComponent) methods are best suited? Maybe there are other extension points in the form creation process, please feel free to make suggestions. Background: for some of our app forms which have a very basic structure (with some PageControls and QuantumGrids) I realized that it is not database access and other stuff in OnFormShow but the construction which took most of the time (around 2 seconds) which makes me wonder where this time is spent. As a reference object I will also build a mock form which has a similar structure but no code or datamodule connections and measure its creation time.

  • Grafting Scala 2.8 into a Netbeans NBAndroid Project...What steps am I missing?

    - by Michael Kohout
    Hi All; Due to Apple's recent T+C hijinks, I've become interested in developing for Android. Anyways, I'm trying to get a mixed-language Android 2.1 project going in Netbeans 6.8 (with the NBAndroid 0.10 plugin). The two languages being Java and Scala(2.8 head build). To give you a basic idea of what the app does right now, it's just a simple "Hello World" app. To get this to build, I've modified the projects's build.xml file: -- -injars ${scala-library}(!META-INF/MANIFEST.MF,!library.properties) -outjars "${build.classes.dir}/classes.min.jar" -libraryjars "${file.reference.android.jar}" -dontwarn -dontoptimize -dontobfuscate -keep public class * extends android.app.Activity -keep public class scala.xml.include.sax.Main** I've gotten the project so that it'll build, but it errors on startup in my Android Emulator(inside the emulator Android tells me my application has stopped unexpectedly). So my questions are: Does anyone see what I may be doing wrong? And is there any way to get access to the logs that the emulator must create? thanks Mike Kohout

  • moving SDL video surface

    - by runrunraygun
    Does anyone know how to move my SDL.net video surface around the screen programtically? Surface videoContext = Video.SetVideoMode(1024, 768, 32, false, false, false, true, true); var a = System.Windows.Forms.Control.FromHandle(Video.WindowHandle); var b = System.Windows.Forms.NativeWindow.FromHandle(Video.WindowHandle); I can't find any properties in Surface or Video which do the job, and FromHandle is returning Null. The window is initializing falling off the bottom of the screen. Any ideas?

  • Open source iPhone components? Reusable views, controllers, buttons, table cells, etc?

    - by Ian Terrell
    Are there any repositories around for open sourced iPhone components? For instance, I have found myself needing to create several new types of table cells to mimic some of Apple's existing functionality (for instance, all the different types of table cells present in the Settings application). I can't imagine I'm alone here. Where do you go to find open sourced reusable components, or do you just write and hoard your own? Update: I know there are open source full projects around (see this question), but rummaging through them and picking and choosing still leads to significant duplication of effort. Update 2: Here are some libraries that I've found (or have come into existence) since asking this question: Three20 -- Custom UI classes used in the Facebook application CocoaHelpers -- Extensions to common classes MBProgressHUD -- Replacement for the undocumented UIProgressHUD

  • dotnet nuke error

    - by donfigga
    Hi there im trying to degub a dot net nuke server error and im not sure where to start. I dnt have the code locally else I could debug (no that im familiar the dnn setup). This bug affects making cms updates to the site with the message 'A critical error has occured', I have been unsuccessfully trying to find out the cause and im finally throwing up my hands, I dont even need a fix , I just want to find out what is causing the error so I can provide an estimate for a fix and I can even seem to do that. I have tried looking at the logs but nothing seems to be logged about this error, is there a way to turn off custom error handling so as to get some clues as what the cause of this bug is? any suggestions would be welcome as i am getting desperate here :)

  • implicit argument passing of super from method defined by define_method() is not supported. Specify

    - by jaycode
    Most of you should already know Pragmatic book's "Agile web dev with rails" (third edition). On page 537 - 541 it has "Custom Form Builders" code as follows: class TaggedBuilder < ActionView::Helpers::FormBuilder # <p> # <label for="product_description">Description</label><br/> # <%= form.text_area 'description' %> #</p> def self.create_tagged_field(method_name) define_method(method_name) do |label, *args| @template.content_tag("p" , @template.content_tag("label" , label.to_s.humanize, :for => "#{@object_name}_#{label}") + "<br/>" + super) end end field_helpers.each do |name| create_tagged_field(name) end end This code doesn't work with Ruby 1.9.1. It returns error as follows: implicit argument passing of super from method defined by define_method() is not supported. Specify all arguments explicitly. (ActionView::TemplateError) My question is: What should I change in the code to fix this? Thank you

  • How can I get the Visual Studio 2010 converstion wizard to come back up?

    - by 2GDave
    When I first opened my website project with Visual Studio 2010 the conversion wizard came up and I said that I didn't want to convert the project. Now I'm ready to convert the project, but I can't find a shortcut or a way to get it back? I tried to remove the suo file, and that didn't do it. If I go into the project properties I can switch the target framework to 4.0, but that tells me it's going to close and reopen the project and I'll have to adjust the pages by hand - doesn't seem like very much fun. Anyone know how to get it to prompt again, or even a command line that would run it? Thank you!

  • Capturing SOAP requests to an ASP.NET ASMX web service

    - by pcampbell
    Consider the requirement to log incoming SOAP requests to an ASP.NET ASMX web service. The task is to capture the raw XML being sent to the web service. The incoming message needs to be logged for debug inspection. The application already has its own logging library in use, so the ideal usage would be something like this: //string or XML, it doesn't matter. string incomingSoapRequest = GetSoapRequest(); Logger.LogMessage(incomingSoapRequest); Are there any easy solutions to capture the raw XML of the incoming SOAP requests? Which events would you handle to get access to this object and the relevant properties?

  • ASP.NET - dynamically creating database connection in datasets

    - by Foo
    I am currently using datasets for my data access layer. I currently store the connection string in the web.config file. I need the ability to change the connection to another database before any queries are processed. Is there an event that is triggered or a base class that can be modified that intercepts the process of retrieving the connection string from the web.config file? Is there any way to handle multiple database connections using the same code base and also take advantage of the connection pooling? I understand the best method is to get rid of datasets and use custom data objects. Any ideas?

  • Cleanup for control inside a FlowDocument

    - by Thorarin
    I have a custom control that I use inside a FlowDocument. The control uses a System.Drawing.ImageAnimator to display transparent, animated GIF images. Why is this such a pain in the butt in WPF anyway? :P In my original implementation, this was causing memory leaks when a paragraph containing the control was being deleted from the document, because the ImageAnimator kept a reference to the control for event handling. I've now implemented a WeakEventManager pattern which seems to indeed fix the leak itself, but I would like to stop "OnFrameChanged" events from being fired if a particular animated GIF is not currently in the document, instead of relying on the garbage collector to eventually collect the control objects and my event manager to notice that there no longer are valid listeners to the event. Basically, I would like to take a more active role in this and have the control react to being removed from the FlowDocument. Is there some way to do this? I've been unable to find it. OnVisualParentChanged doesn't get fired, because the direct parent (a Paragraph) is unchanged.

  • Importing Swift classes within a Objective-C Framework

    - by theMonster
    I have a custom Framework that has a bunch of Objective-C Classes. Within the Framework, I'd like to add more classes using Swift. However, when trying to expose the Swift classes to the Objective-C code using: MyProduct-Swift.h, it comes up as "MyProduct-Swift.h file not found". I've tried this in a single view template and it works fine. Is it not possible to import Swift within a framework? I've also verified that I have set the Defines Module setting and the Module Name. I've tried it with and without these settings.

  • accessing embedded object with jquery not working in firefox 3.6

    - by taber
    Hi, this code in my plugin used to work just fine: jQuery('#embedded_obj', context).get(0).getVersion(); and in html... <object id="embedded_obj" type="application/x-versionchecker-1.0.0.1"</object Basically trying to get the properties from an embedded object. But it looks like get(0) is returning an html object instead of the actual embedded object. For example, if I do: var launcher = jQuery('#embedded_obj', context).get(0); for(prop in launcher){ alert(prop + ': ' + launcher[prop]); } ... it alerts things like "getElementByNode," "scrollWidth," "clientLeft," "clientTop" etc. Again this worked before Firefox 3.6. Has anyone else seen this or have any ideas/suggestions? Thanks!

  • Loading a UIDatePicker in Landscape on a UINavigationController

    - by Ryan
    I have a custom UINavigationController that supports auto-rotate. I also have a UIDatePicker on one of my views that I throw onto the stack of the Navigation controller. The auto-rotate works if I start the date picker view in portrait and then rotate it. If I try load the date picker view in landscape to begin with, the view is all messed up. It looks like it would if it didn't support rotation and the frame only has about half of the picker visible and off center. I've tried making my own date picker that supports auto-rotate in case that was the problem, I've tried creating two different views and swapping them out, and I've tried changing the view frame size on the ViewWillAppear method. None of them seem to be working for me as of yet. Anyone have any suggestions on how to get the date picker to show up in landscape correctly on a navigation controller? I probably am overlooking something simple and the answer is right in front of me, but I'm not finding it.

  • Is there a way to put relationships/contraints into CSS?

    - by hekevintran
    In every design tool or art principle I've heard of, relationships are a central theme. By relationships I mean the thing you can do in Adobe Illustrator to specify that the height of one shape is equal to half the height of another. You cannot express this information in CSS. CSS hard-codes all values. Using a language like LESS that allows variables and arithmetic you can get closer to relationships but it's still a CSS variant. This inability in my mind is the biggest problem with CSS. CSS is supposed to be a language that describes the visual component of a Web page but it ignores relationships and contraints, ideas that are at the core of art. How possible is it to imagine a new Web design language that can express relationships and contraints that can be implemented in JavaScript using the current CSS properties?

  • How to setup a DotNetNuke Development Environment with Source Control?

    - by Joosh21
    My team is developing a new DotNetNuke web application and would like to know what is recommended to setup a development environment with source control and automated builds? We would like to keep the DNN source code separate from our custom modules and extensions source code. The DotNetNuke Compiled Module template for Visual Studio wants us to store the source code in the DesktopModules directory of the DNN source code and output to the DNN source code bin directory. Is this the recommended structure? I would rather keep the files in different locations, but then it becomes more difficult to run and debug locally as it would require an install of the module for each change. Also, how should an automated build deploy any changes? How have others set this up? Is there a recommended best practice?
