  • How to override equals method in java

    - by Subash Adhikari
    I am trying to override equals method in java. I have a class People which basically has 2 data fields name and age. Now I want to override equals method so that I can check between 2 People objects. My code is as follows public boolean equals(People other){ boolean result; if((other == null) || (getClass() != other.getClass())){ result = false; } // end if else{ People otherPeople = (People)other; result = name.equals(other.name) && age.equals(other.age); } // end else return result; } // end equals But when I write age.equals(other.age) it gives me error as equals method can only compare String and age is Integer. Please help me fix this. Thanks is Advance.

  • Using TFSBuild to publish ClickOnce files that include prerequisites

    - by icancsharp
    I have declared an MSBuild tag in my TFSBuild project in order to publish ClickOnce files for my project. WSE 3.0 and .Net 3.0 are both pre-requisites for the application, so in Visual Studio I have ticked those as pre-requisites. When I build from Visual Studio, it creates a setup.exe file that I can publish to my web site. When you browse to this setup.exe file it installs WSE3.0 and .Net 3.0 and then continues to install my application, which works well. If I get TFS to create the click once files using the MSBuild tag in the TFSBuild file, it creates the setup.exe file, which I can publish to my website in the same way (along with all the other ClickOnce files). When I browse to setup.exe now, however, the prerequisites don't get installed and therefore my program does not run. Does anyone know how to get TFS to build a correct setup.exe file that properly bootstraps my prerequisites?

  • Chnaging Displayed Image on a Webpage Using Javascript

    - by Gavin
    Hi all, I'm having some trouble changing an image being displayed on a page by way of a dropdown menu selection. This works fine.. getting the dropdown menu to give me an alert when I make a selection. Even though the menu is embedded within a division, paragraph, and label tag, it still works. "availableImages" is the name of my menu. function imageSelect() { var index = document.getElementById("myForm").availableImages.selectedIndex; var value = document.getElementById("myForm").availableImages.options[index].value; alert("test " + value); // alert box pops up upon list item selection } However, within the same division, I am having an issue with changing the source of my image tag... Any ideas? I will provide more code if it will be helpful. Thanks! Gavin

  • What HTML is permitted within Flash text fields.

    - by JasonS
    Hi, Could someone clarify for me what input Flash accepts for its text fields? I am tasked with managing a content management system, this then generates XML which power's flash sites. I have nothing to do with Flash. I work with PHP. Currently we use a rather temperamental Flash Text Editor which is prone to all sorts of troubles. I tried to plug-in tinyMce but it broke the Flash templates. I then recently spoke to someone who said that flash should take any HTML. Now I am confused as this would point to a dodgy template. Can someone clarify. Do Flash text fields handle all HTML or just a limited subset of HTML. If it is the latter, what happens if it comes across a tag it doesn't recognise? Does it display the tag or break? Thanks, Jason

  • Why does forward declaration not work with classes?

    - by eSKay
    int main() { B bb; //does not compile (neither does class B bb;) C cc; //does not compile struct t tt; //compiles class B {}; struct s { struct t * pt; }; //compiles struct t { struct s * ps; }; return 0; } class C {}; I just modified the example given here. Why is that the struct forward declarations work but not the class forward declarations? Does it have something to do with the namespaces - tag namespace and typedef namespace? I know that the structure definitions without typedefs go to tag namespace. Structures are just classes with all public members. So, I expect them to behave similarly.

  • How to secure licensekey generation

    - by Jakob Gade
    Scenario, simplified for brevity: A developer creates an application for a customer. The customer sells this app to end-users. The app requires a license key to run, and this key is generated by the customer for each end-user with a simple tool created by the developer. The license key contains an expiry date for the license and is encrypted so the end-user can’t tamper with it. The problem here is that the developer (or anybody who has a copy of the license key generator) can easily create valid license keys. Should this generator fall into the wrong hands, it could spell disaster for the customers business. Ideally, the customer would have to use a password to create new license keys. And this password would be unknown to the developer, and somehow baked into the decryption algorithm in the application so it will fail if an attempt to use an unauthorized key is made. How would you implement a solution for this problem that is both transparent and secure?

  • Prevent line break between two elements in CSS

    - by Paul Alexander
    For some basic layout work I'm doing, I'd like links that immediately follow a price to always be shown on the same line as the price. The price text is wrapped in a <span class="price"> tag while the link uses the buy-link class as in <a href="/buy" class="buy-link">Buy Now</a>. I'm looking for CSS that will automatically prevent line breaking between the span and a tag but I'm either missing something or it can't be done. I can easily prevent line breaks within the two tags - but not between them. I want to avoid wrapping both tags in a span with a white-space: nowrap manually and use pure CSS if possible.

  • Web scraping with Python

    - by Jack
    I'm currently trying to scrape a website that has fairly poorly-formatted HTML (often missing closing tags, no use of classes or ids so it's incredibly difficult to go straight to the element you want, etc.). I've been using BeautifulSoup with some success so far but every once and a while (though quite rarely), I run into a page where BeautifulSoup creates the HTML tree a bit differently from (for example) Firefox or Webkit. While this is understandable as the formatting of the HTML leaves this ambiguous, if I were able to get the same parse tree as Firefox or Webkit produces I would be able to parse things much more easily. The problems are usually something like the site opens a <b> tag twice and when BeautifulSoup sees the second <b> tag, it immediately closes the first while Firefox and Webkit nest the <b> tags. Is there a web scraping library for Python (or even any other language (I'm getting desperate)) that can reproduce the parse tree generated by Firefox or WebKit (or at least get closer than BeautifulSoup in cases of ambiguity).

  • ASP.NET ASPX Designer question. Bug?

    - by Velika
    Check out this Screenshot. Shouldn't a hierarchy list of tags appear here? Usually it appears. Sometimes, the tag "appears" there but without text (but the tag object is there as evident when you hover over it.) Other times, like this, nothing appears. It's a usual feature to see the hierarchy or tags which gives me easily access to the tags from design view for easy altering in the properties window. I think too many developers love to do things the hard way and sludge thru tags in HTML view and hardly use this, but it frustrates me when it doesn't work all the time. Is it me? Nah....

  • Send instance method to module

    - by Matchu
    Given the following module, module Foo def bar :baz end end def send_to_foo(method) # ...? end send_to_foo(:bar) # => :baz What code should go in send_to_foo to make the last line work as expected? (send_to_foo is obviously not how I would implement this; it just makes clearer what I'm looking for.) I expected Foo.send(:bar) to work at first, but it makes sense that it doesn't. It would if the method were defined as def self.bar, but that's no fun.

  • Rails: Cannot add :precision or :scale options with change_column in a migration?

    - by Josh Pinter
    This seems to have been asked before: http://stackoverflow.com/questions/1402547/rails-decimal-precision-and-scale But when running a change_column migration for :precision or :scale they don't actually affect the schema or database, but db:migrate runs without errors. My migration file looks like this: class ChangePrecisionAndScaleOfPaybackPeriodInTags < ActiveRecord::Migration def self.up change_column :tags, :payback_period, :decimal, { :scale => 3, :precision => 10 } end def self.down change_column :tags, :payback_period, :decimal end end But my schema (and the data) remains as: t.decimal "rate" # previous column t.decimal "payback_period" t.string "component_type" # next column Anybody else have this issue? Thanks, Josh

  • D-Day Calendar has wrong dates when importing from google calendar?

    - by chobo2
    Hi I am using D-Day calendar and I am not sure but I got a weird problem. I basically have this for my code iCalendar iCal = iCalendar.LoadFromStream(file.InputStream); foreach (Event evt in iCal.Events) { DateTime start = evt.DTStart.Date; DateTime end = evt.DTEnd.Date; // loop through it and get values. } Yet when I import a calendar from google calendar the end date is messed up on some of the stuff I am importing. Like for instance I have this Title: should not show When: Sun, March 21(all day). Yet when I import it in. I says the start date is the 21st yet the end date is the 22nd when it should be the 21st. Not sure what is going on. I am not really sure what other info I can give you guys.

  • Ruby on Rails - nested attributes: How do I access the parent model from child model

    - by TMaYaD
    I have a couple of models like so class Bill < ActiveRecord::Base has_many :bill_items belongs_to :store accepts_nested_attributes_for :bill_items end class BillItem <ActiveRecord::Base belongs_to :product belongs_to :bill validate :has_enough_stock def has_enough_stock stock_available = Inventory.product_is(self.product).store_is(self.bill.store).one.quantity errors.add(:quantity, "only #{stock_available} is available") if stock_available < self.quantity end end The above validation so obviously doesn't work because when I'm reading the bill_items from nested attributes inside the bill form, the attributes bill_item.bill_id or bill_item.bill are not available before being saved. So how do I go about doing something like that?

  • Admin interface in Rails

    - by yuval
    I have an admin controller located in controllers/admin/admin_controller.rb I also have a pages controller located in controllers/admin/pages_controller.rb pages_controller.rb inherits from admin_controller.rb in routes.rb, I have an admin namespace as such: map.namespace :admin do |admin| admin.resources :pages end I want the admin have basic CRUD functionality in pages_controller.rb (I know how to do that) I want the index and show methods to be available to front-end users I would like the show and index actions to use separate views, but the same code. Questions: Should I create a new pages_controller for the front-end, or share the methods index and show? If share, how would I display separate views depending on whether the url is /admin/pages or /pages If share, should I place pages_controller in /controllers/admin (where it is now) or just in /controllers? Thank you very much.

  • Win XP error 0x80041003 using GetObject/winmgmts

    My computer is called "neil" and I want to set some values using WMI in vbScript. I adapetd the script below from one supplied by Microsoft. When I run it in my browser I get Error Type: (0x80041003) /dressage/30/pdf2.asp, line 8 I suspect it is some registry/security setting. Any advice? John Lewis FULL SCRIPT call Print_HTML_Page("http://neil/dressage/ascii.asp", "ascii") Sub SetPDFFile(strPDFFile) Const HKEY_LOCAL_MACHINE = &H80000002 strKeyPath = "SOFTWARE\Dane Prairie Systems\Win2PDF" strComputer = "."

The line breaks seem to have been introduced in the process of paasting into this form. Well spotted - I was using a PDF file name "ascii". I added a .pdf extension but still get the error. I suspect you're right that it's to do with admin rights. Here's more about the setup and what I'm trying to achieve. Win2pdf is a product for writing PDFs by works by simulating a Windows printer. You "print" the page, select win2pdf in the print dialog and it then asks for a file name. I have it installed on my pc (called Neil) and it works fine in this conventional way. My aim is to write an html page to a PDF file using win2pdf - but via ASP/vbscript/javascript rather than with manual intervention. The script for doing this was provided by win2PDF's tech support but when it did not work, that was the limit of their understanding. In the sample script the file ascii.asp just produces a table of ascii codes/characters. The URL given is on my own PC which has IIS set up to run scripts which it does fine. The error I get occurs on about the fourth line executed. I am logged in with full admin rights - I think! But I'm no expert. I hope this helps to give some more specific suggestions about how to check/fix the admin rights.

  • Rails form submission

    - by Danny McClelland
    Hi Everyone, I have a simple form to enter details of a new case (kase), it's working well and clicking submit stores the information and takes the user to the show.html.erb page. However, I wanted to move part of the form to the sidebar - to make things a little easier to see and use for the user, however, when I moved the section to the sidebar - anything entered during either a creation or edit within those sidebar fields is ignored.

  • touchesBegan / Ended incorrectly identifying second, third, etc. touch

    - by Rob
    I have an issue where touchesBegan and touchesEnded are incorrectly identifying my second, third, etc touch if I continue to hold down my first touch. If I lift my finger up off the first touch, then it will recognize the next touch just fine. It's only when I hold my first touch down continuously and then try and touch a different area with a different finger at the same time. It will then incorrectly register that second touch as being from the first touch again. Any insights into how I can fix this? - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; NSString* filename = [listOfStuff objectAtIndex:[touch view].tag]; // do something with the filename now } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { ITouch* touch = [touches anyObject]; NSString* buttonPressed = [listOfStuff objectAtIndex:[touch view].tag]; // do something with this info now }
