  • How to create a registry key in 64bit view from a 32bit application, using native windows api.

    - by George Kas
    I'm kind of a noob when it comes to windows api. I try to create a registry key in the 64bit view of the registry, from a 32bit application using System::Call "${RegCreateKeyEx}(${HKEY_LOCAL_MACHINE}, 'SOFTWARE\SecureW2\Methods\Default\Profiles\26\ConfigData', 0, 'REG_BINARY', 0x00000000L, 0x0100, NULL, .r5, .r6) .r3" (it's nsis scripting), but it doesn't seem to work.

  • Handling touches in UITableViewController

    - by subw
    I want to implement the handling of an additional swipe gesture in my UITableViewController. However, it seems that in the case of tableviews the usual touch handling methods like -[touchesBegan::] of the controller are not called. How can I handle touches on a UITableView?

  • Looking to write a Tag class

    - by Austin Schneider
    I'm looking to write a Tag class (a tag is a string with no spaces). My first thought is to inherit from String: class Tag < String def initialize(str) raise ArgumentError if str =~ /\s/ super end end Does this look correct? Are there any other methods I should redefine?

  • Increase text size in Ubuntu 10.04 due to having large resolution/monitors

    - by Sridhar Ratnakumar
    I have 24" dual monitors with 1920x1080 resolution on both of them. Consequently the text appears so small. I use the following text-intensive applications frequently: Web browser (Google Chrome) IDE (Komodo) Terminal (Gnome Terminal) Email (Thunderbird) I can configure text size on IDE, Terminal and Email. But for Chrome, it is not a good idea to set proportional font size because often one wants to see the entire (not just proportional fonts) site to be zoomed. So I am asking: Is it possible to increase DPI in Ubuntu (much like on Windows) so as to increase the text size across all apps? OR Is it possible to set permanent 'zoom' in Google Chrome, using a third-party extension maybe? I am using Ubuntu 10.04 (Lucid Lynx)

  • How to find out what is installed on a server

    - by masfenix
    Hi, im an undergrad student and we have special access to a server. The server is a unix server (dont know the OS or anything.. is there a way to find out? ). we also get a website associated with the server. There is a public_html folder. I uploaded with a test file with phpinfo() but the server didnt parse it (yes i had the right extension) . So im guessing PHP isnt installed. is there a way to see what "common" languages ARE installed?

  • Autonegotiate errors between HP and Cisco hardware?

    - by Satanicpuppy
    This is a bit of a specific extension to this question. I've got two ASA's that feed into a Procurve switch, and then into an IPS. All is well except that the procurve absolutely refuses to autonegotiate with the ASA's...The asa's run 100full, and the procurve autonegotiates to 100half. It does it for both ASA's, so it's probably not a failure on one of them, and everything works fine if I force the procurve to 100full. Has anyone else seen this issue? I've been buying more HP hardware, but I'm not keen on getting equipment that's not going to play nice with my Cisco backbone.

  • How to calculate the length of a Path2D in Java?

    - by Sanoj
    I have some paths represented by Path2D. The Path consist of multiple CubicCurve2D or Line2D segments that are connected to each other. I would like to calculate or get the length from the start to the end of a Path. How can I calculate it or get it? Is it possible? I have checked the API documentation, but couldn't find any useful methods.

  • Serializing Class Derived from Generic Collection yet Deserializing the Generic Collection

    - by Stacey
    I have a Repository Class with the following method... public T Single<T>(Predicate<T> expression) { using (var list = (Models.Collectable<T>)System.Xml.Serializer.Deserialize(typeof(Models.Collectable<T>), FileName)) { return list.Find(expression); } } Where Collectable is defined.. [Serializable] public class Collectable<T> : List<T>, IDisposable { public Collectable() { } public void Dispose() { } } And an Item that uses it is defined.. [Serializable] [System.Xml.Serialization.XmlRoot("Titles")] public partial class Titles : Collectable<Title> { } The problem is when I call the method, it expects "Collectable" to be the XmlRoot, but the XmlRoot is "Titles" (all of object Title). I have several classes that are collected in .xml files like this, but it seems pointless to rewrite the basic methods for loading each up when the generic accessors do it - but how can I enforce the proper root name for each file without hard coding methods for each one? The [System.Xml.Serialization.XmlRoot] seems to be ignored. When called like this... var titles = Repository.List<Models.Title>(); I get the exception <Titlesxmlns=''> was not expected. The XML is formatted such as. .. <?xml version="1.0" encoding="utf-16"?> <Titles xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Title> <Id>442daf7d-193c-4da8-be0b-417cec9dc1c5</Id> </Title> </Titles> Here is the deserialization code. public static T Deserialize<T>(String xmlString) { System.Xml.Serialization.XmlSerializer XmlFormatSerializer = new System.Xml.Serialization.XmlSerializer(typeof(T)); StreamReader XmlStringReader = new StreamReader(xmlString); //XmlTextReader XmlFormatReader = new XmlTextReader(XmlStringReader); try { return (T)XmlFormatSerializer.Deserialize(XmlStringReader); } catch (Exception e) { throw e; } finally { XmlStringReader.Close(); } }

  • object array mobile development

    - by mixm
    Im currently creating a tile-based game for android. Using java via dalvik JVM. im fretting over a decision to represent objects in a particular map. should i use an id based map (2 dimensional integer array) and place game logic in a separate function in the game engine, or create an object array (2 dimensional array of game objects) and store game logic within the class methods. i am thinking about the cost of object creation and garbage collection vs extensibility.

  • Website Development moving to Image Hosting

    - by Drew
    We are moving over to using Akamai for all of our large static content so far just flash but are planning to include images, css, and js files in that list. I am curious what methods others employ to switch all of their local/relative paths to using an external hosting company. Also, how they continue to develop their site so that developers can make changes in development without it having to be pushed to their external hosting servers.

  • Odd ActiveRecord model dynamic initialization bug in production

    - by qfinder
    I've got an ActiveRecord (2.3.5) model that occasionally exhibits incorrect behavior that appears to be related to a problem in its dynamic initialization. Here's the code: class Widget < ActiveRecord::Base extend ActiveSupport::Memoizable serialize :settings VALID_SETTINGS = %w(show_on_sale show_upcoming show_current show_past) VALID_SETTINGS.each do |setting| class_eval %{ def #{setting}=(val); self.settings[:#{setting}] = (val == "1"); end def #{setting}; self.settings[:#{setting}]; end } end def initialize_settings self.settings ||= { :show_on_sale => true, :show_upcoming => true } end after_initialize :initialize_settings # All the other stuff the model does end The idea was to use a single record field (settings) to persist a bunch of configuration data for this object, but allow all the settings to seamlessly work with form helpers and the like. (Why this approach makes sense here is a little out of scope, but let's assume that it does.) Net-net, Widget should end up with instance methods (eg #show_on_sale= #show_on_sale) for all the entires in the VALID_SETTINGS array. Any default values should be specified in initialize_settings. And indeed this works, mostly. In dev and staging, no problems at all. But in production, the app sometimes ends up in a state where a) any writes to the dynamically generated setters fail and b) none of the default values appear to be set - although my leading theory is that the dynamically generated reader methods are just broken. The code, db, and environment is otherwise identical between the three. A typical error message / backtrace on the fail looks like: IndexError: index 141145 out of string (eval):2:in []=' (eval):2:inshow_on_sale=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:in send' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2746:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:in each' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2742:inattributes=' [GEM_ROOT]/gems/activerecord-2.3.5/lib/active_record/base.rb:2634:in `update_attributes!' ...(then controller and all the way down) Ideas or theories as to what might be going on? My leading theory is that something is going wrong in instance initialization wherein the class instance variable settings is ending up as a string rather than a hash. This explains both the above setter failure (:show_on_sale is being used to index into the string) and the fact that getters don't work (an out of bounds [] call on a string just returns nil). But then how and why might settings occasionally end up as a string rather than hash?

  • class composition instead of object composition?

    - by fayer
    I want a class property to be reference to another class, not its object and then use this property to call the class's static methods. class Database { private static $log; public static function addLog($LogClass) { self::$log = $LogClass; } public static function log() { self::$log::write(); // seems not possible to write it like this } } any suggestions how i can accomplish this? cause i have no reason making them objects, i want to use the classes for it.

  • HttpURLConnection: Is it necessary to call connect()?

    - by stormin986
    Many examples I've seen don't explicitly call connect(). Instead they just use getInputStream() or getResponseCode(). I'm assuming all of these HttpURLConnection methods that require a connection just call connect() themselves? Are there any cases where connect() must be explicitly called for an HttpURLConnection?

  • Hibernate - on the stack or on the heap?

    - by Stephano
    As a Java programmer, you usually keep two truths in your pocket: Instance variables and Objects lie on Heap. Local variables and methods lie on the Stack. Now that I use Hibernate in just about everything, I realize I'm not as sure of myself. Are there some good rules of thumb for using hibernate and knowing where your memory lives?

  • Spring MVC Best Practice Handling Unrecoverable Exceptions In Controller

    - by jboyd
    When you have a controller that does logic with services and DAO's that may throw an unrecoverable exception, what is the best practice in dealing with those method calls? Currently an app I'm working on has very lengthy try catch methods that simply err.out exception messages, this doesn't seem very robust and I think that this code smells, is there any cookie cutter best practice for handling this in spring-mvc?

  • MPXJ - get ResourceAssignment baseline values

    - by patmortech
    I'm trying to display the Baseline Start, Finish, Cost, and Work values for a ResourceAssignment, but cannot seem to find any methods on the ResourceAssignment object that would provide this information. Anybody know if this is possible? I know the information is stored because I can see it in MS Project, and I can see it in the XML version of the project file. Just can't see in the API where to get access to it.
