  • implement a coverflow UI in an Android web application

    - by ravidor
    I am trying to build a coverflow UI on an Android web application using HTML,CSS, JavaScript and some images. CSS 3D transforms, which are supported in Safari sine 2009 and on the iPhone since version 2.0, is not supported well on the Android. worse then that, the implementation is buggy on Android 2.1 and Android 2.2, and in each version in a different way. Any idea how can I build a coverflow UI on an Android web application using HTML,CSS, JavaScript and some images without CSS 3D transforms?

  • Unable to import Eclipse project to Android studio

    - by Binoy Babu
    Whenever I try to import my Eclipse project to Android Studio I get the following error : You are using an old, unsupported version of Gradle. Please use version 1.8 or greater. Please point to a supported Gradle version in the project's Gradle settings or in the project's Gradle wrapper (if applicable.) Consult IDE log for more details (Help | Show Log) Im using Android Studio 0.3 and Ubuntu, I also tried it on a Windows 8 box with fresh install but getting the same error. I'm using default gradle wrapper and I tried checking and unchecking auto import option. Is this a bug? How can I get around it. How do I update gradle to 1.8 or check the current gradle version? My build.gradle is given below. buildscript { repositories { mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:0.6.3' // I also tried using 0.6.1 and 0.5.+ } } apply plugin: 'android' dependencies { compile fileTree(dir: 'libs', include: '*.jar') } android { compileSdkVersion 18 buildToolsVersion "18.0.1" sourceSets { main { manifest.srcFile 'AndroidManifest.xml' java.srcDirs = ['src'] resources.srcDirs = ['src'] aidl.srcDirs = ['src'] renderscript.srcDirs = ['src'] res.srcDirs = ['res'] assets.srcDirs = ['assets'] } // Move the tests to tests/java, tests/res, etc... instrumentTest.setRoot('tests') // Move the build types to build-types/<type> // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ... // This moves them out of them default location under src/<type>/... which would // conflict with src/ being used by the main source set. // Adding new build types or product flavors should be accompanied // by a similar customization. debug.setRoot('build-types/debug') release.setRoot('build-types/release') } }

  • What are the disadvantages to declaring Scala case classes?

    - by Graham Lea
    If you're writing code that's using lots of beautiful, immutable data structures, case classes appear to be a godsend, giving you all of the following for free with just one keyword: Everything immutable by default Getters automatically defined Decent toString() implementation Compliant equals() and hashCode() Companion object with unapply() method for matching But what are the disadvantages of defining an immutable data structure as a case class? What restrictions does it place on the class or its clients? Are there situations where you should prefer a non-case class?

  • ASP:NET :Problem in DoNut Caching

    - by Shyju
    I have an ASP.NET page where i am trying to do some output caching.But ran into a problem. My ASPX page has <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="MYProject._Default" %> <%@ OutputCache Duration="600" VaryByParam="None" %> <%@ Register TagPrefix="MYProjectUC" TagName="PageHeader" Src="~/Lib/UserControls/PageHeader.ascx" %> <%@ Register TagPrefix="MYProjectUC" TagName="PageFooter" Src="~/Lib/UserControls/PageFooter.ascx" %> and i have used the User control called "PageHeader" in the aspx page. In PageHeader.ascx, i have an asp.net substitution control, where i want to show some links based on the logged in user. <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="PageHeader.ascx.cs" Inherits="MyProject.Lib.UserControls.PageHeader1" %> <div class="headerRow"> <div class="headerLogo"> <a href="Default.aspx"><img src="Lib/Images/header.gif" alt=""></a> </div> <div id="divHeaderMenu" runat="server"> <asp:Substitution ID="subLinks" runat="server" MethodName="GetUserProfileHeaderLinks" /> </div> </div><!--headerRow--> In my ascx.cs file,i have a static method which will return a string based on whether the used logged in or not using session public static string GetUserProfileHeaderLinks(HttpContext context) { string strHeaderLinks = string.Empty; // check session and return string return strHeaderLinks; } But Still the page shows the same content for both logged in user and Guest user. My objective is to to have the Page being cached except the content inside the substitution control. Any idea how to achieve this ? Thanks in advance

  • Are iframes a terrible idea?

    - by jamtoday
    I'm building a widget, and I've been using iframes to present content within it. At some point, I might start serving third party HTML and JS, so I thought iframes would be a good idea. It does make the widget javascript a little more complicated, and I'm concerned that this might not be the best implementation. Do you have any advice? It would be a huge help to hear what other people think about iframes.

  • How to share classes between DLLs

    - by Jamie Hale
    I have an unmanaged Win32 C++ application that uses multiple C++ DLLs. The DLLs each need to use class Foo - definition and implementation. Where do Foo.h and Foo.cpp live so that the DLLs link and don't end up duplicating code in memory? Is this a reasonable thing to do?

  • Why doesn't my android application show up in the launcher?

    - by rushinge
    I'm developing an application for the Android platform targeted for api level 4 (Android 1.6) but I can't get it to show up on my phone and I can't figure out why. Here's my AndroidManifest.xml is there a problem in here? Or is there something else I should be looking at? <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.sbe.app.hellocogen" android:versionCode="1" android:versionName="1.0"> <uses-permission android:name="android.permission.INTERNET" /> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".activity.ListPlants" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".activity.AddPlant" android:label="Add Plant"> <intent-filter> <action android:name="android.intent.action.VIEW"/> <category android:name="android.intent.category.DEFAULT"/> </intent-filter> </activity> <activity android:name=".activity.UnitActivity" android:label="IP HERE, PLANT NAME"> <intent-filter> <action android:name="android.intent.action.VIEW"/> <category android:name="android.intent.category.DEFAULT"/> </intent-filter> </activity> </application> <uses-sdk android:minSdkVersion="4"/> </manifest> When I started this application it didn't show up but I fixed it by setting the minimum api level to 4 instead of 7 then it started showing up but now it stopped showing up again and I don't know why.

  • ASPX FormsAuthentication.RedirectFromLoginPage function is not working anymore

    - by Mike Webb
    Here is my issue. I have an ASPX web site and I have code in there to redirect from the login page with the call to "FormsAuthentication.RedirectFromLoginPage(username, false);" This sends the user from the root website folder to 'website/Admin/'. I have a 'default.aspx' page in 'website/Admin/' and the call to redirect works on a previous version of the website we have running currently, but the one that I am updating on a separate test server is not working. It gives me the error "Directory Listing Denied. This Virtual Directory does not allow contents to be listed." I have this in the config file: <authorization> <allow users="*" /> </authorization> under the "authentication" option and... <location path="Admin"> <system.web> <authorization> <deny users="?" /> </authorization> </system.web> </location> for the location of Admin. Also, there is no difference in the code between the web.config, Login.aspx, or the default.aspx files on the current server and the one on the test server, so I am confused as to why the redirect will not work on both. It even works in the Visual Studio server environment, for which the code is also identical. Any suggestions and help is appreciated.

  • DUnit: How to run tests?

    - by Ian Boyd
    How do i run TestCase's from the IDE? i created a new project, with a single, simple, form: unit Unit1; interface uses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm1 = class(TForm) private public end; var Form1: TForm1; implementation {$R *.DFM} end. Now i'll add a test case to check that pushing Button1 does what it should: unit Unit1; interface uses Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs, StdCtrls; type TForm1 = class(TForm) Button1: TButton; procedure Button1Click(Sender: TObject); private public end; var Form1: TForm1; implementation {$R *.DFM} uses TestFramework; type TForm1Tests = class(TTestCase) private f: TForm1; protected procedure SetUp; override; procedure TearDown; override; published procedure TestButton1Click; end; procedure TForm1.Button1Click(Sender: TObject); begin //todo end; { TForm1Tests } procedure TForm1Tests.SetUp; begin inherited; f := TForm1.Create(nil); end; procedure TForm1Tests.TearDown; begin f.Free; inherited; end; procedure TForm1Tests.TestButton1Click; begin f.Button1Click(nil); Self.CheckEqualsString('Hello, world!', f.Caption); end; end. Given what i've done (test code in the GUI project), how do i now trigger a run of the tests? If i push F9 then the form simply appears: Ideally there would be a button, or menu option, in the IDE saying Run DUnit Tests: Am i living in a dream-world? A fantasy land, living in a gumdrop house on lollipop lane?

  • StructureMap Autowiring with two different instances of the same interface

    - by Lambda
    For the last two days, i tried my best to learn something about StructureMap, using an old project of mine as an concrete implementation example. I tried to simplify my question as much as possible. While i will post my examples in vb.net, answers with examples in C# are also okay. The project includes an interfaces called IDatabase which connects itself to a Database. The important part looks like this. Public Interface IDatabase Function Connect(ByVal ConnectionSettings As ConnectionSettings) As Boolean ReadOnly Property ConnectionOpen As Boolean [... more functions...] End Interface Public Class MSSQLConnection Implements IDatabase Public Function Connect(ByVal ConnectionSettings As ConnectionSettings) As Boolean Implements IDatabase.Connect [... Implementation ...] End Function [... more implementations...] End Class ConnectionSettings is a structure that has all the information needed to connect to a Database. I want to open the Database Connection once and use it for every single connection in the project, so i register a instance in the ObjectFactory. dim foo = ObjectFactory.GetInstance(Of MSSQLConnection)() dim bar as ConnectionSettings foo.connect(bar) ObjectFactory.Configure(Sub(x) x.For(Of IDatabase).Use(foo)) Up until this part, everything works like a charm. Now, i get to a point where i hav e classes that need an additional instance of IDatabase because they connect to a second database. Public Class ExampleClass Public Sub New(ByVal SameOldDatabase as IDatabase, ByVal NewDatabase as IDatabase) [...] Magic happens here [...] End Sub End Class I want this second IDatabase to behave much like the first one. I want it to use a concrete, single instance and want to connect it to a different database invoking Connect with a different ConnectionSettings. The problem is: While i'm pretty sure it's somewhow possible, (my initial idea was registering ExampleClass with alternative constructor arguments), i actually want to do it without registering ExampleClass. This probably involves more configuration, but i have no idea how to do it. So, basically, it comes down to this question: How do i configurate the ObjectFactory in a way that the autowiring always invokes the constructor with object Database1 for the first IDatabase parameter and object Database2 for the second one (if there is one?)

  • How to use Object.GetHashCode() on a type that overrides GetHashCode()

    - by Jimmy
    Hi, I have a class A that implements IEquatable<, using its fields (say, A.b and A.c) for implementing/overriding Equals() and overriding GetHashCode(), and everything works fine, 99% of the time. Class A is part of a hierarchy (class B, C) that all inherit from interface D; they can all be stored together in a dictionary Dictionary, thus it's convenient when they all carry their own default Equals()/GetHashCode(). However, while constructing A I sometime need to do some work to get the values for A.b and A.c; while that's happening, I want to store a reference to the instance that's being built. In that case, I don't want to use the default Equals()/GetHashCode() overrides provided by A. Thus, I was thinking of implementing a ReferenceEqualityComparer, that's meant to force the use of Object's Equals()/GetHashCode(): private class ReferenceEqualityComparer<T> : IEqualityComparer<T> { #region IEqualityComparer<T> Members public bool Equals(T x, T y) { return System.Object.ReferenceEquals(x, y); } public int GetHashCode(T obj) { // what goes here? I want to do something like System.Object.GetHashCode(obj); } #endregion } The question is, since A overrides Object.GetHashCode(), how can I (outside of A) call Object.GetHashCode() for an instance of A? One way of course would be for A to not implement IEquatable< and always supply an IEqualityComparer< to any dictionary that I create, but I'm hoping for a different answer. Thanks

  • Is it possible to use theme colors in Windows Forms apps?

    - by Yadyn
    I normally make use of System Colors whenever possible when designing Windows Forms applications just so that it'll fit in with the user's preferences. But is it possible to use Theme Colors? I realize that this limits you in several ways (must be running Windows that supports it and has the Themes service running), so I would certainly like it if it could fall back on some other default, but since I'm fairly sure 99% of my users will have it available, I'd like to make use of it if possible. Specifically, for newer Windows versions (Vista and 7), things like hyperlinks have a softer more pastel-ish blue. The old System Colors do not define anything for links and the like, and in general are much more limited (coming from the 95 days) in choices and variety. Though WPF probably has better support, I'm not at liberty to use it. If some third party utility, assembly, or the like is necessary, it would also need to be free to use. I don't need anything that fancy, but in a perfect world I would be able to do something like this: linkLabel1.LinkColor = System.Drawing.ThemeColors.Hyperlink; Am I stuck just using the default Blue (0,0,255) and having them look out of place in Vista and above? I'll even settle for ugly p/invoke interop methods if need be...

  • LINQ 2 SQL: Partial Classes

    - by Refracted Paladin
    I need to set the ConnectionString for my DataContext's based on an AppSetting. I am trying to do this by creating a Partial Class for each DataContext. The below is what I have so far and I am wondering if I am overlooking something? Specifically, am I dealing with my DataContext's correctly(disposing, staleness, etc)? Doing it this way will I have issues with Updates and Inserts? Is the file BLLAspnetdb.cs useful or neccessary in the least or should all of that be in the generated partial class AspnetdbDataContext file? In short, is this an acceptable structure or will this cause me issues as I elaborate it? dbml File Name = Aspnetdb.dbml Partial Class File Name = Aspnetdb.cs partial class AspnetdbDataContext { public static bool IsDisconnectedUser { get { return Convert.ToBoolean(ConfigurationManager.AppSettings["IsDisconnectedUser"]) == true; } } public static AspnetdbDataContext New { get { var cs = IsDisconnectedUser ? Settings.Default.Central_aspnetdbConnectionString : Settings.Default.aspnetdbConnectionString; return new AspnetdbDataContext(cs); } } } My Created File Name = BLLAspnetdb.cs public class BLLAspnetdb { public static IList WorkerList(Guid userID) { var DB = AspnetdbDataContext.New; var workers = from user in DB.tblDemographics where user.UserID == userID select new { user.FirstName, user.LastName, user.Phone }; IList theWorkers = workers.ToList(); return theWorkers; } public static String NurseName(Guid? userID) { var DB = AspnetdbDataContext.New; var nurseName = from demographic in DB.tblDemographics where demographic.UserID == userID select demographic.FirstName +" " + demographic.LastName; return nurseName.SingleOrDefault(); } public static String SocialWorkerName(Guid? userID) { var DB = AspnetdbDataContext.New; var swName = from demographic in DB.tblDemographics where demographic.UserID == userID select demographic.FirstName + " " + demographic.LastName; return swName.SingleOrDefault(); } } see this previous question and the accepted answer for background on how I got to here... switch-connectionstrings-between-local-and-remote-with-linq-to-sql

  • Should an event-sourced aggregate root have query access to the event sourcing repository?

    - by JD Courtoy
    I'm working on an event-sourced CQRS implementation, using DDD in the application / domain layer. I have an object model that looks like this: public class Person : AggregateRootBase { private Guid? _bookingId; public Person(Identification identification) { Apply(new PersonCreatedEvent(identification)); } public Booking CreateBooking() { // Enforce Person invariants var booking = new Booking(); Apply(new PersonBookedEvent(booking.Id)); return booking; } public void Release() { // Enforce Person invariants // Should we load the booking here from the aggregate repository? // We need to ensure that booking is released as well. var booking = BookingRepository.Load(_bookingId); booking.Release(); Apply(new PersonReleasedEvent(_bookingId)); } [EventHandler] public void Handle(PersonBookedEvent @event) { _bookingId = @event.BookingId; } [EventHandler] public void Handle(PersonReleasedEvent @event) { _bookingId = null; } } public class Booking : AggregateRootBase { private DateTime _bookingDate; private DateTime? _releaseDate; public Booking() { //Enforce invariants Apply(new BookingCreatedEvent()); } public void Release() { //Enforce invariants Apply(new BookingReleasedEvent()); } [EventHandler] public void Handle(BookingCreatedEvent @event) { _bookingDate = SystemTime.Now(); } [EventHandler] public void Handle(BookingReleasedEvent @event) { _releaseDate = SystemTime.Now(); } // Some other business activities unrelated to a person } With my understanding of DDD so far, both Person and Booking are seperate aggregate roots for two reasons: There are times when business components will pull Booking objects separately from the database. (ie, a person that has been released has a previous booking modified due to incorrect information). There should not be locking contention between Person and Booking whenever a Booking needs to be updated. One other business requirement is that a Booking can never occur for a Person more than once at a time. Due to this, I'm concerned about querying the query database on the read side as there could potentially be some inconsistency there (due to using CQRS and having an eventually consistent read database). Should the aggregate roots be allowed to query the event-sourced backing store for objects (lazy-loading them as needed)? Are there any other avenues of implementation that would make more sense?

  • TinyMCE + jQuery + custom plugin = tinymce is undefined?

    - by user368691
    The problem occurs when I try to create small plugin to allow me toggle on and off WYSIWYG on all textareas in the website. //$('form.default textarea').each(function(){ // console.log( $('<a href="#">Enable WYSIWYG editor</a>').insertAfter('form.default textarea').prev('textarea.wysiwyg').tinymce().hide() ); //}); The full (a bit simplified) code looks like this: $('textarea.wysiwyg').tinymce({ skin : 'cirkuit', theme : 'advanced', plugins : 'pagebreak,style,layer,advlink,inlinepopups,contextmenu,paste,directionality,noneditable,nonbreaking,xhtmlxtras,template', // Theme options theme_advanced_buttons1 : 'formatselect,fontsizeselect,forecolor,|,bold,italic,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,|,link,unlink,|,image,|,code,paste,pastetext,pasteword,removeformat,|,backcolor,|,underline,justifyfull,sup,|,outdent,indent,|,hr,charmap,|,undo,redo', theme_advanced_buttons2 : '', theme_advanced_buttons3 : '', theme_advanced_toolbar_location : 'top', theme_advanced_toolbar_align : 'left', theme_advanced_statusbar_location: 'bottom', theme_advanced_resizing : true, theme_advanced_resize_horizontal : false, height : 500, theme_advanced_resizing_min_height : 500, document_base_url : 'http://static.<?=$settings['system_host']?>/' }); $('textarea.wysiwyg').each(function() { $(this).tinymce().hide(); }); What is the error? FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.

  • Grails - Simple hasMany Problem - How does 'save' work?

    - by gav
    My problem is this: I want to create a grails domain instance, defining the 'Many' instances of another domain that it has. I have the actual source in a Google Code Project but the following should illustrate the problem. class Person { String name static hasMany[skills:Skill] static constraints = { id (visible:false) skills (nullable:false, blank:false) } } class Skill { String name String description static constraints = { id (visible:false) name (nullable:false, blank:false) description (nullable:false, blank:false) } } If you use this model and def scaffold for the two Controllers then you end up with a form like this that doesn't work; My own attempt to get this to work enumerates the Skills as checkboxes and looks like this; But when I save the Volunteer the skills are null! This is the code for my save method; def save = { log.info "Saving: " + params.toString() def skills = params.skills log.info "Skills: " + skills def volunteerInstance = new Volunteer(params) log.info volunteerInstance if (volunteerInstance.save(flush: true)) { flash.message = "${message(code: 'default.created.message', args: [message(code: 'volunteer.label', default: 'Volunteer'), volunteerInstance.id])}" redirect(action: "show", id: volunteerInstance.id) log.info volunteerInstance } else { render(view: "create", model: [volunteerInstance: volunteerInstance]) } } This is my log output (I have custom toString() methods); 2010-05-10 21:06:41,494 [http-8080-3] INFO bumbumtrain.VolunteerController - Saving: ["skills":["1", "2"], "name":"Ian", "_skills":["", ""], "create":"Create", "action":"save", "controller":"volunteer"] 2010-05-10 21:06:41,495 [http-8080-3] INFO bumbumtrain.VolunteerController - Skills: [1, 2] 2010-05-10 21:06:41,508 [http-8080-3] INFO bumbumtrain.VolunteerController - Volunteer[ id: null | Name: Ian | Skills [Skill[ id: 1 | Name: Carpenter ] , Skill[ id: 2 | Name: Sound Engineer ] ]] Note that in the final log line the right Skills have been picked up and are part of the object instance. When the volunteer is saved the 'Skills' are ignored and not commited to the database despite the in memory version created clearly does have the items. Is it not possible to pass the Skills at construction time? There must be a way round this? I need a single form to allow a person to register but I want to normalise the data so that I can add more skills at a later time. If you think this should 'just work' then a link to a working example would be great. Hope this makes sense, thanks in advance! Gav
