  • Unmodifiable NavigableSet/NavigableMap in Java?

    - by Greg Mattes
    java.util.Collections has several unmodifiable methods that provide unmodifiable collection views by wrapping collections in decorators that prohibit mutation operations. Java 6 added support for java.util.NavigableSet and java.util.NavigableMap. I'd like to be able to have unmodifiable NavigableSets and NavigableMaps, but java.util.Collections#unmodifiableSortedSet(SortedSet) and java.util.Collections#unmodifiableSortedMap(SortedMap) are not sufficient because they do not support the operations that are particular to NavigableSet and NavigableMap. Are there de-facto implementations for unmodifiableNavigableSet and unmodifiableNavigableMap?

  • Conditional Styling In Silverlight?

    - by DeanMc
    Hi, While I'm fine with standard control styling in silverlight I have recently began using more dynamic methods of fetching data to be displayed in items controls. One of the controls I am reworking is a collection of links. The issue I am having is that each link is coloured differently when moused over. One red, one blue, one green, etc. Is there a way to style these items without sacrificing the dynamics of using an items control with a data template?

  • ASP.NET MVC security: how to check if a controller method is allowed to execute under current user's

    - by Gart
    Given an ASP.NET MVC Controller class declaration: public class ItemController : Controller { public ActionResult Index() { // ... } public ActionResult Details() { // ... } [Authorize(Roles="Admin, Editor")] public ActionResult Edit() { // ... } [Authorized(Roles="Admin")] public ActionResult Delete() { // .. } } I need to reflect a list of methods in this class which may be invoked with the current user's permissions. Please share some ideas of what could be done in this case.

  • Convert UTF-16 to UTF-8 under Windows and Linux, in C

    - by DooriBar
    I was wondering if there is a recommended 'cross' Windows and Linux method for the purpose of converting strings from UTF-16LE to UTF-8? or one should use different methods for each environment? I've managed to google few references to 'iconv' , but for somreason I can't find samples of basic conversions, such as - converting a wchar_t UTF-16 to UTF-8. Anybody can recommend a method that would be 'cross', and if you know of references or a guide with samples, would very appreciate it. Thanks, Doori Bar

  • How to Instantiate ObjectFrame in VB.NET

    - by Suman
    I am trying to reach methods and properties of ObjectFrame through vb.net. But when I declared this as Dim objOLEObject As ObjectFrame and then trying to instantiate it as ObjOLEObject = New ObjectFrame it shows error like: "429: Retriveing the COM class factory for component with CLSID {3806e95d-e47c-11-cd-8701-00aa003f0f7} failed due to the following error: 80040154" To resolve this we re-installed both MS-Office 2003 and VS-2005, but could not get the solution. Could anyone suggest me how to declare and use this in vb.net? Thanks.

  • how can I implement Comparable more than once?

    - by codeman73
    I'm upgrading some code to Java 5 and am clearly not understanding something with Generics. I have other classes which implement Comparable once, which I've been able to implement. But now I've got a class which, due to inheritance, ends up trying to implement Comparable for 2 types. Here's my situation: I've got the following classes/interfaces: interface Foo extends Comparable<Foo> interface Bar extends Comparable<Bar> abstract class BarDescription implements Bar class FooBar extends BarDescription implements Foo With this, I get the error 'interface Comparable cannot be implemented more than once with different arguments...' Why can't I have a compareTo(Foo foo) implemented in FooBar, and also a compareTo(Bar) implemented in BarDescription? Isn't this simply method overloading?

  • In ASP.NET MVC (3.0/Razor), do you prefer multiple views, or conditionals within views? Why?

    - by Chad
    For my new web app, I'm debating on using multiple views, or conditionals within views. An example scenario would be showing different info to users who are authenticated vs non-authenticated. This could be handled a couple ways. In the controller, check IsAuthenticated and return a view based on that In the view, check IsAuthenticated and show blocks of info based on that Pros of multiple views: Smaller, less complicated view - next to no logic in the view Pros of single views: less view files to maintain The obvious cons are the opposites of the pros: more files to maintain or more complicated view files. Which do you prefer? Why? Any pros/cons I haven't outlined here? Update: Assume each view uses a layout page and partial views to abstract the obviously repetitive code.

  • Convert SQL server datetime fields to compare date parts only, with indexed lookups

    - by Caveatrob
    I've been doing a convert(varchar,datefield,112) on each date field that I'm using in 'between' queries in SQL server to ensure that I'm only accounting for dates and not missing any based on the time part of datetime fields. Now, I'm hearing that the converts aren't indexable and that there are better methods, in SQL Server 2005, to compare the date part of datetimes in a query to determine if dates fall in a range. What is the optimal, indexable, method of doing something like this: select * from appointments where appointmentDate='08-01-2008' and appointmentDate<'08-15-2008'

  • Is there a simple way to emulate friendship in php 5.3

    - by Itay Moav
    I need some classes to befriend other classes in my system. Lack of this feature made me publicize some methods which shouldn't be public. The consequences of that are that members of my team implement code in a bad and ugly way which causes a mess. Is there a way to define a friendship in php 5.3? (I am aware of http://bugs.php.net/bug.php?id=34044 You might want to vote there if there is no simple solution).

  • php date() function displaying wrong time

    - by ladaghini
    I'm building a site with wordpress, and when I use the date() function on an otherwise empty file, it shows the right date. However, if I use it in a file that includes other wordpress files, the time is displayed as GMT time, so the date is off. If anyone can figure out how I can use date function without interruption from the wordpress methods, I'd appreciated it.

  • Get length of bits used in int

    - by sigvardsen
    If you have the binary number 10110 how can I get it to return 11111? e.g a new binary number that sets all bits to 1 after the first 1, there are some likewise examples listed below: 101 should return 111 (3 bit length) 011 should return 11 (2 bit length) 11100 should be return 11111 (5 bit length) 101010101 should return 111111111 (9 bit length) How can this be obtained the easiest way in Java? I could come up with some methods but they are not very "pretty".

  • How to set the Windows Mobile 6 IME mode (to numbers only)

    - by Daniel Crenna
    In Windows Mobile 5 one of the following methods works to set an input to numbers only: // Managed InputModeEditor.SetInputMode(textBox, InputMode.Numeric); // Native Wrapper InputModeSupport.SHSetImeMode(textBox.Handle, InputModeSupport.SHIME_MODE.SHIME_MODE_NUMBERS); In Windows Mobile 6, neither works. How do you set the IME to "Numbers Only" in WM 6.0 / .NET CF 3.5?

  • Method Vs Property

    - by obsoleteattribute
    Hi, I'm a newbie to .NET. I have a class called Project, a project can have multiple forecasts.Now If I want to check if the projects has any forecasts or not should I use a readonly boolean property called HasForecast() or should I use a method named HasForecast() which basically returns a boolean value.From framework design guidelines I came to know that methods should be used when the operation is complex,since here I'm retrieving the value of forecasts from DB should I consider method, or since it is a logical data member should I use a property.If I use a property can I call a method in DBLayer from its getter.Please explain Regards, Ravi

  • Capturing USB Plug/Unplug events in Firemonkey

    - by radsdau
    [RAD Studio XE3 / C++] I have a FMX project running in Windows only at this stage, but I need to detect events when USB devices are connected and disconnected. I have a similar VCL app that can do this fine, but the Application-HookMainWindow is not exposed in FMX (only VCL). Is there an elegant way to handle this? Or do I have to hack some VCL stuff into my FMX app to make that work? I'd imagine I have to abstract it so I can support other platforms down the track. For the meantime though I need to get the Windows solution working. If the 'VCL hack' thing is required, how would I reference the vcl::Forms::Application from within my Fmx app? Cheers.

  • What's faster Model.get(keys) or Model.get_by_id(ids, parent=None)

    - by WooYek
    I'm wondering is there a difference in terms of computing cost for the Model.get(keys) and Model.get_by_id(ids, parent=None) methods? Is there a server side computing advantage of using numeric id's over encoded string keys, or other way around? How big is the difference? PS. Sorry, if it's a dupe. I'm sure I read an article about it, but I cannot find it now.

  • Is there any graphics library in a higher level than OpenGL

    - by Turtle
    Hello, I am looking for a graphics library for 3D reconstruction research to develop my specific viewer based on some library. OpenGL seems in a low level and I have to remake the wheel everywhere. And I also tried VTK(visualization toolkit). However, it seems too abstract that I need to master many conceptions before I start. Is there any other graphics library? I prefer to program in python. So I would like the library has a python wrapper. I think something like O3D would be better. But O3D is for javascript and it seems that Google already stops the development.
