  • syntax problem crating a method that returns an object (java)

    - by David
    I'm trying to create a method that will sum two timeO objects and return a new TimeO object called sum. Here is the relevant code snippet: public static TimeO add (TimeO t1, TimeO t2) { TimeO sum = new TimeO ; ... } When i try to compile it i get this error message: TimeO.java:15: '(' or '[' expected TimeO sum = new TimeO ; ^ 1 error i cant think of any reason why it would want me to open a set of parenthasies or brackets here but its possible that i dont' quite understand the syntax. Whats going wrong here?

  • I18n translation problem

    - by kshchepelin
    I'm about to translate all time zones to Russian and I've done such things: model: # lib/i18n_time_zone.rb class I18nTimeZone < ActiveSupport::TimeZone def self.all super.map { |z| create(z.name, z.utc_offset) } end def to_s translated_name = I18n.t(name, :scope => :timezones, :default => name) "(GMT#{formatted_offset}) #{translated_name}" end end view: <%= time_zone_select :user, :time_zone, nil, :model => I18nTimeZone %> locale file (/config/locales/ru.yml): ru: timezones: "Midway Island": "??????" "Samoa": "?????" .... But there are cases when original string includes some dots (".") Like "St. Petersburg" And I18n.t() tells me that translation is missing. How can I avoid it?

  • Heuristic for sliding tile problem.

    - by MustDash
    The idea is to move all of the right elements into the left and the left into the right with an empty space in the middle. The elements can either jump over one or two pieces into an empty space. LLL[ ]RRR I'm trying to think of a heuristic for this task. Is the heuristic meant to aid in finding a possible solution, or actually return a number of moves as the solution? How would I express such a heuristic?

  • How do you solve this Haskell problem?

    - by Linda Cohen
    I want to define a function replicate to replicate a list of numbers by its value using only list comprehension, for example: replicate [5,1,3,2,8,1,2] output: [5,5,5,5,5,1,3,3,3,2,2,8,8,8,8,8,8,8,8,1,2,2] I know this would be easy to use the 'replicate' built in function but only list comprehension is allow, how can I do this? THANKS!

  • Passing class method as selector problem.

    - by Anoide
    Hi, I want to build a selector from a class method. I'm doing it this way: NavigationTreeActionHandler* handler=[NavigationTreeActionHandler self]; NavigationTreeNode* bombsNode=new NavigationTreeNode("Bombs","bigbomb.tif" ,handler,@selector(BigBombButtonPressed:)); I need to pass to NavigationTreeNode the target and the selector to the target method. I try to get the target using the self property of the class object (Don't know if htis is the correct way to do it). Then I get the selector for the class method I want to call on the class. Everything compiles ok but it fails when I use: [[handler class] instanceMethodSignatureForSelector:selector]; I get a nil and don't really know why... could anybody help please? Thanks in advance, Olson.

  • Loading multiple embedded flash apps onto an HTML page- problem with ordering

    - by shudson250
    We need to load an embedded version of a site written in Flash, and not originally designed to load multiple instances of itself, on a HTML page. The specific issue is how to get them to load in order when embedded, given that they are all being opened by the same instance of the flash player. It's a complicated mapping application, and at the moment, the maps and data get intermixed as the session variables are overwritten by another instance starting to load before the previous one has finished. We need a way to have them load sequentially, one finishing before another starts to load. The most we can specify in the URL is an &order=1 or similar. We have PHP and SQL on the backend. Edit: The embedded versions are being loaded in an iFrame of a parent site. One php file loads one swf, as many times as the parent site desires.

  • Problem with non-copyable classes

    - by DeadMG
    I've got some non-copyable classes. I don't invoke any of the copy operators or constructor, and this code compiles fine. But then I upgraded to Visual Studio 2010 Ultimate instead of Professional. Now the compiler is calling the copy constructor- even when the move constructor should be invoked. For example, in the following snippet: inline D3D9Mesh CreateSphere(D3D9Render& render, float radius, float slices) { D3D9Mesh retval(render); /* ... */ return std::move(retval); } Error: Cannot create copy constructor, because the class is non-copyable. However, I quite explicitly moved it.

  • Obj-c method override/polymorphism problem

    - by Rod
    Ok, so I'm using Objective-C. Now, say I have: TopClass : NSObject - (int) getVal {return 1;} MidClass : TopClass - (int) getVal {return 2;} BotClass : MidClass - (int) getVal {return 3;} I then put objects of each type into an NSMutableArray and take one out. What I want to do is run the getVal func on the appropriate object type, but when I put id a = [allObjects objectAtIndex:0]; if ([a isKindOfClass:[TopClass class]]) { int i; i = [a getVal]; } I get firstly a warning about multiple methods called getVal (presumably because the compiler can't determine the actual object type until runtime). But more seriously I also get an error "void value not ignored as it should be" and it won't compile. If I don't try and use the return from [a getVal] then it compiles fine e.g. [a getval]; //obviously no good if I want to use the return value It will also work if I use isMemberOfClass statements to cast the object to a class before running the function e.g. if ([a isMemberOfClass:[BotClass]) i = [(BotClass*) a getVal]; But surely I shouldn't have to do this to get the functionality I require? Otherwise I'll have to put in a statement for every single subclass, and worse have to add a new line if I add a new sub class, which rather defeats the point of method overriding doesn't it? Surely there is a better way?

  • Problem with user logins after db Restore

    - by JJgates
    I have two SQL 2005 instances that reside on different networks. I need to backup a database from instance A and restore it to a database in instance B on a weekly basis so that both databases hold the same data. After the restore, logins SIDS on database B are changed and therefore users can't log into database B and connection strings for the web application it supports are broken. Is there a work around for this? Thanks.

  • JavaScript OOP problem

    - by Danmark
    I create windows like this: var obj = document.createElement('div'); obj.className = 'window'; obj.style.width = 300 + 'px'; obj.style.height = 200 + 'px'; obj.style.left = 30 + 'px'; obj.style.top = 200 + 'px'; //and so on and what I need is to attach some data to each window. The data will be grabbed via Ajax and displayed in the windows. How should I do it so that each window hold its own unique data? I don't need to display the whole data every time and this data would need be organized before being displayed, so I can't just add it with innerHTML. I need a way to hold it somewhere else where I could easily get it and then display it with innerHTML.
