  • Android ==> Simple 2d Animation ???

    - by aryaxt
    public void MoveMyButton (int x) //where the button suppose to move to { TranslateAnimation anim=new TranslateAnimation(this.getLeft() ,x, this.getTop() ,20)); anim.setFillAfter(true); anim.setDuration(1000); this.setAnimation(anim); anim.start(); } button's x at start is 1. I call the method to move it to 100, and it goes from 1 to 100 I call it to go to 200, and it goes from 1 to 200, instead of 100 to 200 Is there any way to make the animation to save the location of the button as it animates it? Thanks

  • Simple Prototype.js code to select multiple elements with the same classname

    - by stephemurdoch
    I have one link with an id of "link", and I use the javascript below to open that link up in a modalbox: #In my template I have: <a href="some/path" id="link">link</a> #Then in my application.js file I have: document.observe('dom:loaded', function() { $('login-link').observe('click', function(event) { event.stop(); Modalbox.show(this.href,{title: 'some title', width: 500}); }); }) Since id's must be unique, this javascript only works for one element per page so I use it to observe my login-link and it has served me well. Until now. I want to use the same javascript to observe multiple links which have classnames instead of id's as below: <a href="link/to/some/stuff" class="link">link 1</a> <a href="link/to/some/other/stuff" class="link">link 2</a> When I do this, I can't get any of the links to open in a modalbox. If I change the class to an id for each link, then I can get the first link in the list to open in a modalbox. I've tried to use the '$$' notation to build an array of links in my javascript (shown below) but if I do that, then none of the links open correctly #document.observe method removed for display purposes $$('link').observe('click', function(event) { event.stop(); Modalbox.show(this.href,{title: 'some title', width: 500} ); }); My javascript skills obviously suck. Does anyone know how to fix the problem?

  • PHP: Simple, Validate if string is hex?

    - by oni-kun
    I have no clue how to validate this string. I am simply supplying an IV for an encryption, but can find no "is_hex()" or similar function, I can't wrap my head around it! I read on a comment in the php documentation (user contrib. notes) this: if($iv == dechex(hexdec($iv))) { //True } else { //False } But that doesn't seem to work at all.. It only says false. If it helps my input of my IV would be this: 92bff433cc639a6d

  • Simple File-based Record Storage with Fast Text Searching for Compact Framework and Silverlight

    - by Eric Farr
    I have a single table with lots of records ( 100k) that I need to be able to index and search on several text fields. The easiest searches will have the first part of the string specified (eg, LIKE 'ABC%' in SQL). The tougher searches will need to search for any substring within the text fields (eg, LIKE '%ABC%' in SQL). I need to run on the Compact Framework. SQL Compact is a memory hog and overkill for my one table. Besides, I'd like to be able to run on Silverlight 4 eventually. The file and indexes can be generated on the full .NET Framework and I only need read capability on the Compact Framework. My records are not especially large and can be expressed in fix length format. I'm looking for some existing code or libraries to avoid having to write a file-based BTree implementation from scratch.

  • how do simple SQLAlchemy relationships work?

    - by Carson Myers
    I'm no database expert -- I just know the basics, really. I've picked up SQLAlchemy for a small project, and I'm using the declarative base configuration rather than the "normal" way. This way seems a lot simpler. However, while setting up my database schema, I realized I don't understand some database relationship concepts. If I had a many-to-one relationship before, for example, articles by authors (where each article could be written by only a single author), I would put an author_id field in my articles column. But SQLAlchemy has this ForeignKey object, and a relationship function with a backref kwarg, and I have no idea what any of it MEANS. I'm scared to find out what a many-to-many relationship with an intermediate table looks like (when I need additional data about each relationship). Can someone demystify this for me? Right now I'm setting up to allow openID auth for my application. So I've got this: from __init__ import Base from sqlalchemy.schema import Column from sqlalchemy.types import Integer, String class Users(Base): __tablename__ = 'users' id = Column(Integer, primary_key=True) username = Column(String, unique=True) email = Column(String) password = Column(String) salt = Column(String) class OpenID(Base): __tablename__ = 'openid' url = Column(String, primary_key=True) user_id = #? I think the ? should be replaced by Column(Integer, ForeignKey('users.id')), but I'm not sure -- and do I need to put openids = relationship("OpenID", backref="users") in the Users class? Why? What does it do? What is a backref?

  • Simple time profiling - strange times

    - by Gacek
    I'm trying to profile my code to check how long it takes to execute some parts of my code. I've wrapped my most time-consuming part of the code in something like that: DateTime start = DateTime.Now; ... ... // Here comes the time-consuming part ... Console.WriteLine((DateTime.Now - start).Miliseconds); The program is executing this part of code for couple of seconds (about 20 s) but in console I get the result of something about 800 miliseconds. Why is that so? What am I doing wrong?

  • Why isn't this simple PHP Forloop working?

    - by Jake
    First here's the code: <?php $qty = $_GET['qty']; for($i=0; $i < $qty; $i++) { setcookie('animals', $_COOKIE['animals'].'(lion)', time()+3600); } ?> Here's what I'm trying to do: I want to set the value of the "animals" cookie to "(lion)". The number of instances of "(lion)" that should be in the cookie is determined by the "qty" GET parameter's value. So for example if the pages url is: http://site.com/script.php?qty=10 then the value of the cookie should be: (lion)(lion)(lion)(lion)(lion)(lion)(lion)(lion)(lion)(lion) but now it just sets the value once despite the setcookie function being inside the loop, why isn't it working?

  • PHP: Need help with simple XML

    - by Jack
    I am beginner in PHP. I am trying to parse this xml file. <relationship> <target> <following type="boolean">true</following> <followed_by type="boolean">true</followed_by> <screen_name>xxxx</screen_name> <id type="integer">xxxx</id> </target> <source> <notifications_enabled nil="true"/> <following type="boolean">true</following> <blocking nil="true"/> <followed_by type="boolean">true</followed_by> <screen_name>xxxx</screen_name> <id type="integer">xxxxx</id> </source> </relationship> I need to get the value of the field 'following type="boolean" ' for the target and here's my code - $xml = simplexml_load_string($response); foreach($xml->children() as $child) { if ($child->getName() == 'target') { foreach($child->children() as $child_1) if ( $child_1->getName() == 'following') { $is_my_friend = (bool)$child_1; break; } break; } } but I am not getting the correct output. I think the ' type="boolean" ' part of the field is creating problems. Please help.

  • Problem accessing variable in a nested form partial

    - by brad
    I have a nested form in a rails view that is called like this <% f.fields_for :invoice_item_numbers do |item_no_form| %> <%= render 'invoice_item_number', :f => item_no_form %> <% end %> and the partial (_invoice_item_number.html.erb) looks like this <div class='invoice_item_numbers'> <% if f.object.new_record? %> <li><%= f.label :item_number %><%= f.text_field :item_number %> <%= link_to_function "remove", "$(this).parent().remove()", :class => 'remove_link' %></li> <% else %> <li class="inline"><%= f.label :item_number %><%= f.text_field :item_number %> </li><li class="inline"><%= f.label :description %><%= invoice_item_number.description %></li><li><%= f.label :amount %><%= f.text_field :amount %> <%= f.check_box '_destroy', :class => 'remove_checkbox' %> <%= f.label '_destroy', 'remove', :class => 'remove_label' %></li> <% end %> </div> This fails with the error message undefined method `description' for nil:NilClass Why does invoice_item_number return a nil object in this partial? It is obviously being defined somehow because if I change it to something else (e.g. item_number.description then the error message becomes undefined local variable or methoditem_number' for #instead. The invoice_item_number object that is being displayed by this partial is being used perfectly well by the form helpers as<%= f.text_field :item_number %and<% f.text_field :amount %both work perfectly well. I have tried a number of solutions such as using@invoice_item_number` and explicitly defining an object in the render method but these have not worked. Presumably there is a very simple answer to this.

How do I do the following: Update my entity and Save the changes to it. Catch the exception if my changes have been made since I loaded my entity.

  • ruby on rails-Problem with the selection form helper

    - by winter sun
    Hello I have a form in witch users can add their working hours view them and edit them (All in one page). When adding working hours the user must select a project from a dropdown list. In case the action is adding a new hour record the dropdown field should remain empty (not selected) in case the action is edit the dropdown field should be selected with the appropriate value. In order to overcome this challenge I wrote the following code <% if params[:id].blank?%> <select name="hour[project_id]" id="hour_project_id"> <option value="nil">Select Project</option> <% @projects.each do|project|%> <option value="<%=project.id %>"><%=project.name%></option> <% end%> </select> <% else %> <%= select('hour','project_id', @projects.collect{|project|[project.name,project.id]},{:prompt => 'Select Project'})%> <% end %> So in case of save action I did the dropdown list only with html, and in case of edit action I did it with the collect method. It works fine until I tried to code the errors. The problem is that when I use the error method: validates_presence_of :project_id it didn't recognize it in the html form of the dropdown list and don’t display the error message (its working only for the dropdown with the collect method). I will deeply appreciate your instructions and help in this matter

  • SQL Simple ORDER BY

    - by AeroDroid
    I'm new to SQL and I don't think this question should be hard to answer. I have a high-score table for a game that contains the columns name, score, and rank. I want to know how I can order the table by descending order each time a new score is added so the table can always stay ordered by score. I know this is the wrong way of doing this, but I hope this makes my point kind of clearer. UPDATE `HSTable`.`Highscores` ORDER BY `Highscores`.`score` DESC; What is the correct way of approaching this? One more thing, is there a way I can set it so that the ranking value always stays where it's suppose to be from the SQL, for example, 1st place is always at the top regardless the score? Thanks!

    I am developing a VS 2008 web application in C#. I am trying to include a namespace that is stored in one of my folders. So instead of: using ADONET_namespace it is stored in "Admins" folder. How do I modify this aspx.cs file to include Admins/ADONET_namespace? Currently I get following error from aspx.cs file: The type or namespace name 'ADONET_namespace' could not be found (are you missing a using directive or an assembly reference?)
