How to stop affecting more than one class with jQuery?
|
<p>I created this simple function and it works fine apart from the fact that I have more than one ".cta-mask" on the page. What do I need to do to stop affecting all the ".box-hover" when hover one of the ".cta-mask". Code bellow:</p>
<pre><code>$(document).ready(function() {
//header box
$('.box-hover').css('opacity' , '.6');
$('.cta-mask').hover(function(){
$('.box-hover').stop().animate({left:'-12px', opacity:'0.8'},{queue:false,duration:300})
}, function(){
setTimeout(function() {
$('.box-hover').stop().animate({left:'-190px', opacity:'.6'},{queue:false,duration:600})
}, 500)
});
});

Changing Object Parameter Names On-The-Fly

<p>If I have the following:</p>
<pre><code>var myObj = { "Foo":{"prop1":"abc", "prop2":123 }, "Bar":{"prop1":"def", "prop2":456 } };
</code></pre>
<p>Is there a quick and safe way to modify the object such that it becomes:</p>
<pre><code>{ "Foo":{"prop1":"abc", "prop2":123 }, "Bar":{"PROP1":"def", "PROP2":456 } }
</code></pre>
<p>I'd like to change the casing of the property names of the Bar property on-the-fly. Is this possible?</p>

Class extending Application in Android project library?
|
<p>I have a project (in Eclipse) which I've turned into an Android Project Library so as to re-use some of the code in another similar project. I think I've shot myself in the foot however as I'm getting the error:</p>
<pre><code>Unable to start activity ComponentInfo{com.test.scroller1/com.lib.scrolltest.ScrollTestActivity}: java.lang.ClassCastException: android.app.Application cannot be cast to com.lib.scrolltest.resAppVars
</code></pre>
<p>com.lib.scrolltest is my Project Library which instantiates a class extending Application (resAppVars). In the onCreate() method I call:</p>
<pre><code>mRav = (resAppVars) getApplicationContext ();
</code></pre>
<p>This way, I can use methods in the mRav object which would otherwise be a lot of duplicated code in other classes (such as passing a query to a generic select statement which returns an ArrayList of results).</p>
<p>What's the problem here? It seems I've hit a limitation in the way I've implemented the Application class. </p>

C++ size aware data type/parameter

<p>I am not sure, but I think I have once seen a method signature that looked like this (in the constructors):</p>
<pre><code>class Buffer {
Buffer(char_with_size *data) { ... };
Buffer(char *data, size_t len) { ... };
};
</code></pre>
<p>In the first constructor call an array/pointer parameter can passed of which the compiler automatically knows its size. So, I always know the size of the char buffer passed.</p>
<p>Does anyone know if this really exists in c++?</p>

Potential malicious uses of javascript?

<p>In Firefox 6, you can no longer put javascript in the address bar because of security risks such as recent scripts on facebook. I understand it can simulate just about anything you can click, like removing friends and spamming wall posts, but what's the absolute worst? It can only manipulate the page you're on because of cross-domain iframe javascript being disabled, unless it sends an XMLHttpRequest based on cookie data. </p>

jquery prevent double tapping the same element
|
<p>Hy, i'v got a horizontal css menu. When clicked on a tab i do a toggle to switch between the css selected class. This class just removes the bottom-border and colors the font, so it seems like it's an active tab. That's al fine, problem is, i would not like to toggle again when clicking on the same tab that's active.</p>
<p>Example: </p>
<p>-> click on home
-> | <strong>Home</strong> | tab selected.
-> click on home again
-> | Home | tab deselected. </p>
<p>This is the on ready code: </p>
<pre><code>$('#tabmenu li').click(function(e) {
$(this).toggleClass("clicked");
$("#tabmenu li").not(this).removeClass("clicked");
});
</code></pre>
<p>CSS:</p>
<pre><code>#tabmenu li.clicked {
/*remove a piece of UL bottom-border*/
border-bottom: 1px solid #fff;
margin-bottom: -1px;
/*make it show active*/
border-top:1px solid #7C798E;
border-left:1px solid #7C798E!important;
border-right:1px solid #7C798E;
}
#tabmenu li.clicked a { color:#000070;}
</code></pre>
<p>PS.</p>
<p>I thought of doing something like: </p>
<p>... //which element are you
...//temp save
....// are you the same as last one?
.....// YES? -> do nothing, NO -> toggle.</p>
<p>Is there a more brighter way to do this? thx. </p>

Call this (public) function inside private function
|
<p>I have the following javascript: (<a href="http://jsfiddle.net/Mansfield/7XEYD/2/" rel="nofollow">JSFiddle</a>)</p>
<pre><code>$(function () {
function Cat()
{
this.Meow = function (sound) {
alert("Meow: " + sound);
}
this.Kick = function () {
MakeNoise();
}
var MakeNoise = function () {
Meow("noise");
//Cat.Meow("noise");
//self.Meow("noise");
//this.Meow("noise");
}
}
var c = new Cat();
c.Kick();
});
</code></pre>
<p>When I call the <code>Kick</code> function, I get the error "Meow is not defined" (with any of the four things I tried in the <code>MakeNoise</code> function).</p>
<p>I also tried prototyping like so but that gave me the same error:</p>
<pre><code>Cat.prototype.Meow = function (sound) {
return this.Meow(sound);
}
</code></pre>
<p>I've sure this has a terribly straightforward solution, but I can't figure out how to successfully call the <code>Meow</code> function of the "Cat" class. How can I do this?</p>
<p>As an aside, does this architecture make any sense at all? My intention was to have <code>Kick</code> and <code>Meow</code> as public functions, and <code>MakeNoise</code> as private.</p>

python NotImplemented constant

<pre><code>class A(object):
def __lt__(self, a):
return NotImplemented
def __add__(self, a):
return NotImplemented
</code></pre>
<p><a href="http://docs.python.org/library/constants.html">Python docs says</a></p>
<blockquote>
<p>NotImplemented:
Special value which can be returned by the “rich comparison”
special methods (<strong>eq</strong>(), <strong>lt</strong>(),
and friends), to indicate that the
comparison is not implemented with
respect to the other type.</p>
</blockquote>
<p>It doesn't talk about other special methods and neither describes the behavior</p>
<p>It seems to be a magic object which if returned from other special methods raises TypeError, and in “rich comparison” special methods does nothing</p>
<p>e.g.</p>
<pre><code>print A() < A()
</code></pre>
<p>prints True, but</p>
<pre><code>print A() + 1

Getting data from a webpage

<p>I have an idea for an App that would really help me out in work but I'm not sure if it's possible.</p>
<p>I want to run a C# desktop application that will ask for a value. When a value is supplied, the application will open a browswer, go to a webpage and add the value into a form on an online website. The form is then submitted and a new page is loaded that contains a table of results. I then want to extract the table of results from the page source and write code to parse the result values.</p>
<p>It is not important that the user see's this happen in an actual browser. In other words if there's a way to do it by reading HTTP requests then thats great.</p>
<p>The biggest problem I have is getting the values into the form and then retrieving the page source after the form is submitted and the next page loads.</p>
<p>Any help really appreciated.</p>

why is stroull() not working on a byte array with hexadecimal values?
|
<p>here is some new test code with regards to my long issue.
I figure that if i code my stuff as long long then that is half the battle in porting.
the other half would be to make it into big endian so it can work on any 64 bit system.
so i did the following:</p>
<pre><code>#include <iostream>
#include "byteswap.h"
#include "stdlib.h"
using namespace std;
int main()
{
char bytes[6] = {0x12,0x23,0xff,0xed,0x22,0x34};
//long *p_long = reinterpret_cast<long*> (bytes);
long long *p_long = reinterpret_cast<long long*> (bytes);
std::cout<<"hex="<<std::hex<<*p_long<<"LE"<<std::endl;
*p_long = bswap_64(*p_long);
std::cout<<"hex="<<std::hex<<*p_long<<"BE"<<std::endl;
return 0;
}
</code></pre>
<p>this seems to me the simplest way of doing it. the problem now is at using bswap...i get the following output</p>
<p>hex=34563422edff2312LE
hex=0BE</p>
<p>i got all the bytes in the first as LE. but now it seems the 64bit swap function is not working. I think this would solve the issue i am having. </p>
<p>considering that i will be operating on a 20 byte array. i am also not sure how i would use pointers to do that. i am thinking i would need an array of long long pointers to get all this stuff stored and then call the byteswap on each to swap the values in each of those pointers. I personally have not done pointer incrementation via sizeof(long) to increment before.</p>

Comparing Two Arrays resulting into Third Array
|
<p>I have two Arrays:</p>
<pre><code>firstArray=[['AF','AFGHANISTAN'],['AL','ALBANIA'],['DZ','ALGERIA'],['AS','AMERICAN SAMOA']]
secondArray=[[1,'AFGHANISTAN'],[3,'AMERICAN SAMOA']]
</code></pre>
<p>So I just need an Array which is like</p>
<pre><code>thirdArray=[[1,'AF'],[3,'AS']]
</code></pre>
<p>I tried <code>any(e[1] == firstArray[i][1] for e in secondArray)</code>
It returned me True and false if second element of both array matches. but i don't know how to build the third array.</p>

Extending Int to implement interface in c#
|
<p>Is it possible in C# (and I think it's not) to extend <code>int</code> to implement an interface (without creating a wrapper class)?</p>
<p>I have an interface like so</p>
<pre><code>public interface IActionLoggerObject
{
string GetForLogging();
}
</code></pre>
<p>I would like to (conceptually) be able to do this:</p>
<pre><code>public class int:IActionLoggerObject
{
string IActionLoggerObject.GetForLogging() { return "s"; }
}

PHP: How to display page before the script is over?
|
<p>My script consists of two parts.
The first part generates HTML page.
The second part loads a resourse from the net and saves it into a file.
Loading is a long operation and can take up to 10 seconds.
The first and the second parts are completely indepenent (loading has no impact on the look of the page).</p>
<p>At the end of the first part I call flush(), that makes page displayed instantly.</p>
<p>However, embedded SWF movie is not displayed at this moment.</p>
<p>SWF is the key element of the page and it must be displayed as fast as possible.
It is embedded in the page with SwfObject library.
And the problem is that SwfObject starts to open SWF on "onLoad" event of the page.</p>
<p>But "onLoad" event comes at the end of the <em>second</em> part.
That is "onLoad" can occure in 10 seconds.
So in spite flush() call the user has to wait for 10 seconds in vain.</p>
<p>Is it possible to solve the task on PHP side?
Is it possible to run "loading" task (the second part) in a separate process?
Is it possible to tell the browser before the second part starts, that the page is reay and you can broadcast the "onLoad" event.</p>
<p>Thanks for reading this very long story.</p>

ReflectionClass::newInstance/newInstanceArgs generates undefined property

<p>When I try to create a new instance with constructor arguments via the <code>ReflectionClass</code> object I get this notice:</p>

Do database update notifications only happen within the same Activity/Fragment context?
|
<p>I've got a FragmentActivity that shows a list of items and clicking on one starts a new Activity which allows the user to edit that item. This is all using the new <code>CursorLoader</code> support from the v4 compat library. Everything is working (finally!) but when I return from the Edit, the changes are not showing up in the list.</p>
<p>I suspect this is due to the cursor just being reloaded upon resuming the "List" activity and perhaps since it is a separate activity it does not receive any "update" notification from the edit Activity? All the database updates are doing notification as:</p>
<pre><code>getContext().getContentResolver().notifyChange(uri, null);
</code></pre>
<p>Is this working as it's supposed to (i.e. notifications only happen within one context) and I need to force a <code>restartLoader</code> operation when returning from the edit?</p>
<p>Or (as usual) is something else going on?</p>

How to identify whether a variable is a class or an object

<p>I am working at a bit lower level writing a small framework for creating test fixtures for my project in Python.

a2 = 'Val2'
class B(MyBase):
a1 = 'Val3'
a2 = A

Measure column width in TableLayout
|
<p>I have a TableLayout with 4 columns. In order to stretch column 1 I do:</p>
<pre><code>android:stretchColumns="1"
</code></pre>
<p>This works well. Now I need to measure the width of this column 1 once it's displayed on the screen. I need to do this because I want to fit a custom view into this column. This custom view is just a rectangle which shall fill into the complete width of this column 1. I draw the rectangle by:</p>
<pre><code>public class TaskRectangleView extends View {
private ShapeDrawable mDrawable;
private Paint textPaint;
private String task;
public TaskRectangleView(Context context, String task, int width, int height) {
super(context);
this.task = task;
int x = 10;
int y = 10;
mDrawable = new ShapeDrawable(new RectShape());
int color = DbSettingsManager.getInstance(context).getColorByName(task);
mDrawable.getPaint().setColor(color);
mDrawable.setBounds(x, y, x + width, y + height);
textPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
textPaint.setColor(Color.WHITE);
textPaint.setTextSize(10);
}
protected void onDraw(Canvas canvas) {
mDrawable.draw(canvas);
canvas.drawText(this.task, 10, 20, textPaint);
}
</code></pre>
<p>}</p>
<p>So this custom drawn rectangle should fit into column 1 of my TableView. For this (so I believe) I need to measure the width of the column at display-time. How to do this? Thanks!</p>

Console application becomes ghost and does not show on task manager processes tab
|
<p>My program uses MSSQL database and has been working fine. However, after making some changes including converting from VS2008 to VS2010, generating 32bit application. It starts having the following strange problem:
When I try to shutdown the console by clicking the system menu(X button), it does not shutdown, you can move the console around, you can also click on the left hand system menu such as properties, etc, but the program does not show up on the taskmanger's processes tab, therefore, there is no way to shut it down, but to restart box.</p>
<p>Also, while the program is in this ghost mode, I can actually start another instance. That means the ghost application already release most of the resources such as file handle, db etc.</p>
<p>The problem seems to occur after we have some issues with ms-sql server, such as time out exception. I simulate the situation by throwing an exception in the same db function call, but that does create the ghost situation. box is Windows Server Standard without Hyper-V, SP2, 32bit.</p>

How to implement a paint-update loop?
|
<p>I want to create a paint and update loop in android for game animation on a canvas but I am having trouble as I can't seem to get the threading to work appropriately. It seems to crash almost immediately. Here is what I have tried:</p>
<pre><code> // Create the thread supplying it with the runnable object
Thread thread = new Thread(runnable);
// Start the thread in oncreate()
thread.start();
class runner implements Runnable {
// This method is called when the thread runs
long wait = 1000;
public void run() {
update();
}
public void update()
{
try{
Thread.currentThread();
//do what you want to do before sleeping
Thread.sleep(wait);//sleep for 1000 ms
//do what you want to do after sleeping
}
catch(InterruptedException ie){
//If this thread was interrupted by another thread
}
run();
}
}
</code></pre>
<p>Also when I drop the wait down lower it crashes faster.</p>
<p>Is there a more appropriate way to approach this?</p>
<p>Changed to this:</p>
<pre><code>class runner implements Runnable {
// This method is called when the thread runs
long wait = 10;
boolean blocked = false;
public void run() {
if(!blocked){
blocked = true;
paint();
}
}
public void paint()
{
update();
}
public void update()
{
try{
Thread.currentThread();
//do what you want to do before sleeping
Thread.sleep(wait);//sleep for 1000 ms
//do what you want to do after sleeping
}
catch(InterruptedException ie){
//If this thread was interrupted by another thread

What could cause ASP.NET's executionTimeout to not be enforced running under IIS?

<p>I'm trying to troubleshoot a problem, but I'm unable to reproduce it locally under IIS because no matter how low I set executionTimeout, the requests never time out.</p>
<p>I've tried setting this via the web.config (, via code (Page.Server.ScriptTimeout = 5;).</p>
<p>I'm running with binaries that were compiled in release mode, and debug=false is set in the compilation element.</p>
<p>FWIW, under Cassini (the standalone development webserver), everything works as expected, running out of the same directory off of the exact same assemblies/config files.</p>
<p>Any ideas on what could be causing this?</p>
<p>EDIT: If it's relevant, the development workstation in question is running Win7/IIS7.</p>
<p>EDIT 2: I'm using reflection to write out HttpContext.Current.Timeout, and in both Cassini and IIS, it's writing out the value I expect, so it seems that it's a matter of the limit being enforced as opposed to being set incorrectly.</p>

How do I find the source code for Java SE 6 update 10?
|
<p>At <a href="http://java.sun.com/javase/downloads/index.jsp" rel="nofollow">Java SE Downloads</a> I may for example download:</p>
<ul>
<li>Java SE Runtime Environment (JRE) 6 Update 10</li>
<li>Java SE Development Kit (JDK) 6 Update 10</li>
</ul>
<p>But I can't find any source code for update 10. If I click <a href="http://download.java.net/jdk6/6u3/promoted/b05/index.html" rel="nofollow">Java SE 6 JDK Source Code</a> on the Java SE Downloads page it seems I can only download source for "JDK 6u3 Source". Where can I find the source for update 10? If there isn't any and I use update 10 for development, won't there be serious sync problems if I choose to debug and "step into" the source of a JDK method? (It seems like it should.)</p>

List of keys and values, where the order is set based on order of insertion for both keys and values
|
<p>I basically want a list of lists.</p>
<p>They key will be a GUID, and the Value will be a list of Guids.</p>
<p>The order of inserting the Key, and when I insert the List of Guids in the value should keep the order of when I inserted them.</p>
<p>I want this to use generics.</p>
<p>How can I do this?</p>
<p>e.g.</p>
<pre><code>foreach(var guid in SomeList)
{
foreach(var subGuid in SomeList.Values)
}
</code></pre>
<p><strong>And again, order is important, based on how I inserted them (both key and list of values).</strong></p>

How to scroll programatically a ScrollView?
|
<p>I have a little problem with a ScrollView.</p>
<p>I have a layout for an activity which is made with a ScrollView. This scrollview contains two ListViews.</p>
<pre><code><?xml version="1.0" encoding="utf-8"?>
</code></pre>
<p>
</p>
<pre><code> <ListView android:id="@+id/accountsListView"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:scrollbars="none" />
<ListView android:id="@+id/cardsListView"
android:layout_width="fill_parent"
android:layout_height="wrap_content" android:scrollbars="none" />
</LinearLayout>
</code></pre>
<p>In onCreate method of my activity I compute ListViews height according there contents.</p>
<p>During execution, on activity launch, ScrollView is already scrolled a bit.</p>
<p>So I tried, at the end of onCreate to call method scrollTo(0, 0), but it does not change anything.</p>
<p>Any idea ?</p>
<p>Regards,
Quentin</p>

Why does zip() drop the values of my generator?
|
<p>I was writing an answer to <a href="http://stackoverflow.com/questions/11205037/detect-period-of-unknown-source">this question</a> when noticed that my simple implementation didn't produce correct results. While hunting down the bug, I noticed the following:</p>
<pre><code>In [1]: import itertools
In [2]: gen = itertools.cycle((0,1,2))
In [3]: zip(gen, range(3))
Out[3]: [(0, 0), (1, 1), (2, 2)]
In [4]: zip(gen, range(3))
Out[4]: [(1, 0), (2, 1), (0, 2)]
</code></pre>
<p>For whatever reason, <code>gen</code>'s <code>next()</code> method is called one additioinal time.
To illustrate this, I used the following:</p>
<pre><code>class loudCycle(itertools.cycle):
def next(self):
n = super(loudCycle, self).next()
print n
return n
In [6]: gen = loudCycle((0,1,2))
In [7]: zip(gen, range(3))
0
1
2
0
Out[7]: [(0, 0), (1, 1), (2, 2)]

<p>In JavaScript codes, I have seen people using '+' character to convert string to integer as in - </p>

<p>another way is just using parseInt() method as following - </p>
<pre><code>var i = parseInt("2");

<p>I want to know which one is efficient? </p>
<p>Sorry I should also add that, I am dealing with integers only and the data is huge so even a little difference in performance would be good for me.</p>

How to implement a simple prioritized listener pattern in JavaScript
|
<p>I have an event/listener manager that has this function:</p>
<pre><code> var addListener = function(event, listener) {
myListeners[event].push(listener); //assume this code works
}
</code></pre>
<p>But now I need to change it so that it looks like this:</p>
<pre><code> var addListener = function(event, listener, fireFirst) {
if(fireFirst) {
myListenersToFireFirst[event].push(listener);
} else {
myListenersToFireSecond[event].push(listener);
}
}
</code></pre>
<p>This is so that when the <code>fireEvent</code> function is called, it will fire the listeners in the <code>myListenersToFireFirst</code> array first, then the listeners in the second array.</p>
<p>So it will look something like this:</p>
<pre><code> var fireEvent = function(event) {
var firstListeners = myListenersToFireFirst[event];
//for each listener in firstListeners, call `apply` on it
var secondListeners = myListenersToFireSecond[event];
//for each listener in secondListeners, call `apply` on it
}
</code></pre>
<p>Is this the best way to accomplish this in JavaScript? Is there a more elegant way of achieving this priority list of listener-event firing?</p>

Mapping numbers to letters
|
<p>I had an interview question asking this:</p>
<blockquote>
<p>text file has following lines> </p>
<pre><code> 1: A C D
4: A B
5: D F
7: A E
9: B C
</code></pre>
<p>*Every line has a unique integer followed by a colon and one or
more letters. These letters are
delimited spaces (one or more)> </p>
<pre><code> #2 Write a short program in the language
</code></pre>
<p>of your choice that outputs a sorted
list like</p>
<pre><code> A: 1 4 7
B: 4 9
C: 1 9
D: 1 5
E: 7
F: 5
</code></pre>
</blockquote>
<p>I'm not looking for someone to solve it, but I always get confused with problems like this. I'd like to do it in C# and was wondering should I store each line in a 2d array? What is the best way to handle this. After storing it how do I relist each line with letters rather then numbers? </p>
<p>Just looking for pointers here.</p>

Upgrading to PHP 5.3 - solutions for legacy sites
|
<p>I am about to upgrade a couple of servers from PHP 5.1.6 to PHP 5.3.x, however, we host a number of old websites that would be time-consuming to fix in application code.</p>
<p>As I see it there are 2 solutions: </p>
<ul>
<li>stick the old sites on a separate, compatible server</li>
<li>make minimal (backwards-incompatible) fixes and turn off error reporting</li>
<li>fix all backwards-incompatible and deprecated features in application code</li>
</ul>
<p>The latter 2 options are not preferable given this would be very time-consuming -- bear in mind that there are no unit tests and such. The former will be at additional expense given we'd have to pay for and manage an additional box.</p>
<p>Are there any other options you might suggest trying, or <strong>what in your experience has been the best solution to managing legacy sites?</strong></p>

Handling orientation changes yourself
|
<p>From the documentation regarding the <code>android:configChanges='orientation'</code> attribute of the activity tag in the manifest:</p>
<blockquote>
<p>Note: Using this attribute should be avoided and used only as a last-resort. Please read Handling Runtime Changes for more information about how to properly handle a restart due to a configuration change.</p>
</blockquote>
<p>Why does it say this? </p>
<p>In the case of threads and networking requests via a service API library, a request could be made with a reference to the original Activity, and then an orientation change could occur, leaving the thread pointing to the old Activity.</p>
<p>While this can be fixed, it's tedious and ugly compared to just handling the configuration changes yourself.</p>
<p>Why should it be avoided?</p>
<p>Edit: I guess I should also ask: would this be an acceptable reason for doing the orientation configuration changes yourself?</p>

Intialization of static variables in a class of utility functions
|
<p>For my Android application, I have written a class which is composed of utility functions which are needed at various activites in the application.In this class, I need a context variable(for working with files) and an instance of preference manager and preference editor.Also, a long integer represnting the current date as a timestamp is needed:</p>
<pre><code>private static long today;
private static Context myContext;
private static SharedPreferences sharedPrefs;
private static Editor editor;
</code></pre>
<p>Which is correct way to initialize these variables. I have tried doing it via a private constructor as shown below, but I am getting errrors.</p>
<pre><code>private NetworkController()
{
//Getting the Unix timestamp for today
GregorianCalendar aDate = new GregorianCalendar();
GregorianCalendar tDate = new
GregorianCalendar(aDate.get(Calendar.YEAR),aDate.get(Calendar.MONTH),
aDate.get(Calendar.DAY_OF_MONTH), 0, 0, 0);
today = (tDate.getTimeInMillis())/1000;
//The preferences manager for reading in the preferences
sharedPrefs = PreferenceManager.getDefaultSharedPreferences(myContext);
//The preferences editor for modifying the preferences values
editor = sharedPrefs.edit();
}
</code></pre>
<p>One approach would be to create an instance of this class in every activity where its used but I don,t want to do that.Any other approach is possible?</p>
