JavaScript setSelectionRange() method and cursor position
|
<p>I have the following piece of JavaScript for dynamically inserting unicode characters - represented below by the txtToIns variable - into a body of text</p>
<pre><code>elmt.value = elmt.value.substring(0, elmt.selectionStart) + txtToIns + " " + elmt.value.substring(elmt.selectionStart, elmt.selectionEnd) + elmt.value.substring(elmt.selectionEnd, elmt.value.length) + " ";
elmt.focus();
elmt.value = elmt.value.trim();
</code></pre>
<p>With the above the cursor is always at the end of the text. Is there any way I can place it directly after txtToIns? And no, txtToIns.focus() won't work</p>

JavaScript to start and stop timing
|
<p>I have some problems with JavaScript timings..Basically i want it to start timing when it goes out of focus and when it comes back to focus, the timing will stop and it will display.</p>
<pre><code>var start,end,isTimerOn=0;
window.addEventListener('blur', function() { //when user get out of the screen
/*Start Time when user goes out of focus*/
start = new Date().getTime();
});
window.addEventListener('focus', function() { //when user focus on the screen
if (isTimerOn==1)
{
end = new Date().getTime();
var time = end - start; //time will be in ms. eg: 1 sec will be 1000
/*Convert to seconds*/
var y=Math.round(time/1000);
start=0; //reset
isTimerOn=0; //reset
alert('Execution time: ' + y + 'secs'); //this will print the time how long the user has been away
}
});
</code></pre>
<p>Now the isTimerOn variable is a flag which will be set when:</p>
<pre><code>function ProcessThisSearch(form)
{
//alert("OI!"); //test is js is working.
var test=form.search.value;
//alert(test); //test if value can be retrieved
if (test)
{
isTimerOn=1;
window.open('http://www.'+test+'.com');
}
}
</code></pre>
<p>This function ProcessThisSearch(form) will be invoked in the following HTML form:</p>
<pre><code><form align=right action="mainheader.jsp" method="POST"><input type="text" name="search"><input type="submit" value="Open Website" onClick="ProcessThisSearch(this.form)"></form>
</code></pre>
<p>I believe the problem is with the isTimerOn variable. Because I have tested the two event listener and it is working. Only when I add isTimerOn variable, it doesn't seem to work.</p>

Why is __init__.py not being called?
|
<p>I'm using Python 2.7 and have the following files:</p>
<pre><code>./__init__.py
./aoeu.py
</code></pre>
<p><code>__init__.py</code> has the following contents:</p>
<pre><code>aoeu aoeuaoeu aoeuaoeuaoeu
</code></pre>
<p>so I would expect running aoeu.py to error when Python tries to load <code>__init__.py</code>, but it doesn't. The behavior is the same whether PYTHONPATH is set to '.' or unset.</p>
<p>What's going on?</p>

Does a virtual function override a non-virtual function of the same name in a base class?
|
<p>Is the following standard conforming? Can you cite the section?</p>
<pre><code>struct A
{
virtual void func() = 0;
};
struct B
{
void func(){}
};
struct C : public A, public B
{
virtual void func(){ B::func(); }
};
</code></pre>
<p>I'm getting a strange compiler warning in VS2010 in equivalent but more complicated code pointing to <code>func</code>'s declaration in the derived-most class: <code>warning C4505: unreferenced local function has been removed</code>. I have no idea why the compiler thinks a virtual function declared in a class is a local; however I can't repro that warning in a simpler example.</p>
<h1>Edit:</h1>
<p>I figured out a small repro case for the warning. I think I was going down the wrong path assuming it was related to function hiding. Here's the repro case:</p>
<pre><code>template<typename T>
struct C
{
int GetType() const;
virtual int func() const; // {return 4;} // Doing this inline removes the warning <--------------
};
template<typename T>
int C<T>::GetType() const
{
return 0;
}
template<>
int C<int>::GetType() const
{
return 12;
}
template<typename T>
int C<T>::func() const
{
return 3;
}
// Adding the following removes the warning <--------------------
// template<>
// int C<int>::func() const
// {
// return 4;
// }
</code></pre>
<p>I'm fairly sure this is just a VS2010 bug.</p>

jQuery: How to show an element and use the highlight effect at the same time?

<div id="b" style="display:none">different content</div>

<p>When I click the currently displayed <code>div</code>, I want to hide it and show the other one. This is easy to do:</p>
<pre><code>$('#a').hide();
$('#b').show();
</code></pre>
<p>But now I want to take it a step further and highlight the element as it is being displayed. I think that it will involve <code>effect("highlight")</code>, but I can't get it to work. How do I achieve this?</p>

Duplicating Meta Description when using get_meta_tags function, only want the description
|
<p>When echo'ed out instead of just removing all of the other meta tags it seems to be duplicating the description, for example:</p>
<p>BBC has 13 different meta tags, when I echo out just the description in my script it is duplicating it 13 times.</p>
<pre><code><?php
//make the array
$TAarray = explode("\n", strip_tags($_POST['TAData']));
foreach ($TAarray as $key => &$line) {
$line = trim($line);
// get the meta data for each url
$tags = get_meta_tags($line);
echo '<tr>';
foreach ($tags as $meta)
{
echo (isset($tags['description']))?"<br><br />\nDescription($line):<br>\n".$tags['description']:"<br>\nDescription($line):<br>\nNo Meta Description.";
/*echo '<td>' . $meta . '</td>';*/

Android : Can i call my onresume() inside onpause().?
|
<p>I want that just before my application goes in background the user should get a dialogue box asking if i want to exit this application.
And if user selects no then i want that he should be resumed to my application again instead of launching another application.
So,is it possible in android?
One solution can be like this that i call <strong>onresume()</strong> inside <strong>onpause()</strong> or <strong>onstop()</strong>.But can this be done.
Please help me out.</p>
<hr>
<p>My code is like this:-</p>
<pre><code>public void onPause() {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Do you want to quit");
builder.setCancelable(false);
builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
MytestprojectActivity.this.finish();
}
});
builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
super.onPause();
}
</code></pre>
<p>first i basically want to see if it runs on calling of onpause() or not.
so, what i got is that it pauses my activity, goes to another activity and when my activity restarts then it shows me the dialogue box. m i missing something.?</p>

Create static instances of a class inside said class in Python
|
<p>Apologies if I've got the terminology wrong here—I can't think what this particular idiom would be called.</p>
<p>I've been trying to create a Python 3 class that statically declares instances of itself inside itself—sort of like an enum would work. Here's a simplified version of the code I wrote:</p>
<pre><code>class Test:
A = Test("A")
B = Test("B")
def __init__(self, value):
self.value = value
def __str__(self):
return "Test: " + self.value
print(str(Test.A))
print(str(Test.B))
</code></pre>
<p>Writing this, I got an exception on line 2 (<code>A = Test("A")</code>). I assume line 3 would also error if it had made it that far. Using <code>__class__</code> instead of <code>Test</code> gives the same error.</p>
<pre><code> File "<stdin>", line 1, in <module>
File "<stdin>", line 2, in Test
NameError: name 'Test' is not defined
</code></pre>
<p>Is there any way to refer to the current class in a static context in Python? I could declare these particular variables outside the class or in a separate class, but for clarity's sake, I'd rather not if I can help it.</p>
<p>To better demonstrate what I'm trying to do, here's the same example in Java:</p>
<pre><code>public class Test {
private static final Test A = new Test("A");
private static final Test B = new Test("B");
private final String value;
public Test(String value) {
this.value = value;
}
public String toString() {
return "Test: " + value;
}
public static void main(String[] args) {
System.out.println(A);
System.out.println(B);
}
}
</code></pre>
<p>This works as you would expect: it prints:</p>
<pre><code>Test: A
Test: B
</code></pre>
<p>How can I do the same thing in Python?</p>

Variable not found. Referencing objects from another class
|
<p>Background:</p>
<p>I'm creating a basic download centre on a concurrent server.</p>
<p>I create file objects in the <code>Server class</code> under a main method</p>
<pre><code>File[] files = {
new File("1. Program", "myProgram.jar"),
new File("2. Image", "myPicture.jpg"),
new File("3. Book", "myBook.txt")};
</code></pre>
<p>This references to the <code>File class</code> where I create constructors and getters.</p>
<pre><code>class File {
private String option;
private String fileName;
public File(String option, String fileName) {
this.option = option;
this.fileName= fileName;
}
public String getOption() {
return option;
}
public String getFileName() {
return fileName;
}
public void getFileOptions(File[] files) {
for (File f : files) {
System.out.printf("The option is %s\n", f.getOption());
}
}
}
</code></pre>
<p>I am attempting to call the <code>getFileOptions</code> method from my <code>ServerState class</code>. </p>
<pre><code>theOutput= File.getFileOptions(files);
</code></pre>
<p>The output is a string that is returned to a client.</p>
<p>My IDE says that <code>(files)</code> cannot be found. Any ideas where I'm going wrong? Cam I not return results to a class where the object wasn't initially created? </p>

how to convert array into variables in php

C++ char comparison not working
|
<p>It is probably better to say I am doing something wrong rather then say the comparison isn't working. But, I have been going over this code for some time now.</p>
<p>I have a recursive function. Most of it is working well, so I will only put the part that isn't working:</p>
<pre><code>//In main
string C[] = {"S=>bS",
"S=>aaT",
"T=>aT",
"T=>bU",
"U=>Ua",
"U=>aa"};
CFG CFG1(C);
...
string *code;
char startNT;
//The CFG constructor
CFG::CFG(string C[])
{
code = C;
startNT = code[0][0];
}
...
//Inside of processData recursive function
for(unsigned int i = 0; i < code->size(); i++)
{
if(code[i][0] == startNT)
{
string newStr = code[i].substr(code[i].find(">")+1);
string old = wkString;
//This is the recursive call
if(processData(inString, wkString.replace(wkString.find_first_of(startNT), wkString.find_first_of(startNT)+1, newStr)))
{
return true;
}
cout << wkString << endl;
wkString = old;
}
}
</code></pre>
<p>The comparison that isn't working is code[i][0] == startNT . Well... I should say, isn't working 100% of the time. It works great until half way through the recursive function, code[i][0] becomes 'S' and startNT becomes 'T' (after already proving that it can compare 'S' and 'T' properly somewhere during the call), and it still evaluates to true, which causes the wkString.replace() to break since it can't find the 'T'. </p>
<p>It has been awhile since I have used C++, so I am probably making a stupid mistake. Thanks for any help.</p>

<p>What I want to do is use the existing website that provides a somewhat logical dropdown itself to get the data I need. That dropdown fills a multiple selection dropdown after a selection. </p>
<p>I want to select each option in the first dropdown and then read the data it puts in the second multiple selection dropdown. Is there a way to do this?</p>

What is the correct way to identify an Exception?
|
<p>If exceptions are always fatal, making use of them in Python is easy</p>
<pre><code># moduleB.py
import moduleC
</code></pre>
<p>But evaluating an exception requires more than just it's type, we often need to determine where an exception came from</p>
<pre><code># moduleA.py
try:
import moduleB
except ImportError as e:
print e
if str(e) == "No module named moduleB":
pass
else:
raise
</code></pre>
<p>In some projects this pattern results in a lot of code that is not easy to read. Is this the best way to ensure that I'm catching a local exception? I would like to be able write</p>
<pre><code>import moduleB else pass
</code></pre>

Which is a good opensource user management system?
|
<p>I'm new to php/mySQL and am trying to create a website which will allow users to register. In future, there will be a paid content area where content will be shown based on the payment status. </p>
<p>Is there a good opensource lightweight framework which takes care of the user management part? (Register, edit user info, retrieve lost password etc). I'm a flash platform developer and not aware of how to take care of stuff like session hijacking, XSS etc. </p>
<p>Should I go ahead and learn to do all this on my own, without using any framework? I thought of using Wordpress' user management system, but not sure how easy that would be. Any suggestion would be great.</p>

Android: I am unable to have ViewPager WRAP_CONTENT
|
<p>I have setup a simple ViewPager that has an ImageView with a height of 200dp on each page.</p>
<p>Here is my pager:</p>
<pre><code> pager = new ViewPager(this);
pager.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
pager.setBackgroundColor(Color.WHITE);
pager.setOnPageChangeListener(listener);
layout.addView(pager);
</code></pre>
<p>Despite the height set as wrap_content, the pager always fills the screen even though the imageview is only 200dp. I tried to replace the height of the pager with "200" but that gives me different results with multiple resolutions. I am unable to add "dp" to that value. How do I add 200dp to the pager's layout?</p>

Storage of values?
|
<p>I have a database with 4 tables. Each table has 1 column. 3 of the tables will typically hold only around 8-12 values, the other maybe 100+. The values are basic, color, city, etc. The user clicks a button, up pops a list with values they can select, delete or add.</p>
<p>It seems like a lot to have a table for ~8 values. I was wondering if there was a better way to store this data given that values need to be able to be added, deleted and the number will be dynamic.</p>

Form names with arrays

<p>I would like to convert: <code>"controllers[page[title_new]]"</code> to <code>"controllers[page][title_new]"</code>. So I can fill a form with input fields like:</p>
<pre><code><?php $name = 'controllers[page[title_new]]' ?>
<input type='text' name='<?= $name; ?>'>
</code></pre>
<p>After you submit the form you get $_POST =</p>
<pre><code>array(controllers => array(page => array(title_new = '')));
</code></pre>
<p>Now to display this I would like:</p>
<pre><code><input type='text' name='<?= $name; ?>' value='<?= $_POST[CONVERT($name)]; ?>'>

Store localization texts in database or resource files?
|
<p>Currently in my Asp.Net website I store localization texts in a table in the database. The table has three columns:</p>
<pre><code>TextCode nvarchar(100),
CultureId int,
TextString nvarchar(MAX)
</code></pre>
<p>So every time when I need to get a localized text for a specific culture I just do a simple query.</p>
<p>The main advantage of this method is simple and also I can update the texts while my web app is running.</p>
<p>The obvious drawback is performance. I use resource files for localization in other desktop applications. The reason I chose database is I am under an impression that updating the resource file in asp.net will cause the web app to reload and thus I need to take the site offline when I update the resource file. Is assumption true? What's the "common" approach to store localized texts in Asp.Net?</p>
<p>Thanks </p>

PHP = append a 0 to the end of a string
|
<p>I have this function which takes the average user rating given to an item and converts it to a relevant class:</p>
<pre><code>function get_user_rating_class($urate_ave){
if($urate_ave==='0.0'){
$user_rating_class='unrated_u';
}else{
$round_to = 0.5;
$rounded = round($urate_ave / $round_to) * $round_to;
$removedec = str_replace('.','',$rounded);
if(strlen($removedec)<2){$removedec.'0';}
$user_rating_class='rating_user_'+$removedec;
}
return $user_rating_class;
}
</code></pre>
<p>No when I put a value, say 3.0 into the function it should come out as rating_user_30 but instead it is coming out as rating_user_3, so there must be something wrong with this line:</p>
<p><code>if(strlen($removedec)<2){$removedec.'0';}</code></p>
<p>I thought it might be because It was treating the value $removedec as a number rather than a string so I tried adding this line just before it, but no change:</p>
<pre><code>$removedec = strval($removedec);
</code></pre>
<p>Could someone tell me what I am doing wrong here.</p>

Is tight looping bad?
|
<p>Is tight looping in a program bad?</p>
<p>I have an application that has two threads for a game-physics simulator. An updateGame thread and a render thread. The render thread is throttled by causing the thread to sleep for some milliseconds (to achieve the frame-rate I want) and the updateGame thread (that updates my in game objects positions based off some physics equations) was previously throttled by a 10 millisecond sleep.</p>
<p>However, I recently unthrottled the updateGame thread and the simulation of my objects movement seems to be significantly more realistic now that I have taken out that 10ms sleep. Is it bad to hot loop or have a tight loop?</p>
<pre><code>private class UpdateTask implements Runnable
{
private long previousTime = System.currentTimeMillis();
private long currentTime = previousTime;
private long elapsedTime;
public void run()
{
while(true)
{
currentTime = System.currentTimeMillis();
elapsedTime = (currentTime - previousTime); // elapsed time in seconds
updateGame(elapsedTime / 1000f);
try {
Thread.currentThread().sleep(1);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
previousTime = currentTime;
}
}
}
</code></pre>
<p>In this example I'm just sleeping for 1ms (and from my understanding with how millisecond accuracy and the sleep function works this is probably more like 5-10ms. If I sleep for any more than this it starts to have impacts on the accuracy of my collision detection and physics model.</p>
<p>Is it a bad practice to have tight loops or loops with 1ms sleeps in them? Is there something else I should do instead?</p>

Custom Android Layouts
|
<p>I have an upcoming project that requires me to make a custom layout. I have been looking all over for a way to complete this but with no success. The layout will have custom buttons that need to fit the screen and some other custom views. In other words I need it to look the same on all types of devices. So these custom views need to stretch to fit the screens. Something similar to the weather bug app but the buttons will be at the top and there won't be so many options. The buttons will fit the screen width wise. Basically the layout will not contain any stock UI.</p>
<p>I would like to have a book or tutorial that I could follow to help me out here. </p>

I don't understand the last output for this block of code
|
<p>Well, this code was taken from a practice exam for a programming thing that i'm very under qualified for, but i'd still like to know the reason behind the output for this.</p>
<pre><code> #include <iostream>
using namespace std;
int main(){
char g = 'X', t = '1', *k_ = &t;
g = 'y';
cout << *k_ << *k_ << endl;
g = 'Y';
cout << *k_;
k_ = &g;
t = 'Z';
cout << *k_ << *k_ << *k_ << endl;
return 0;
}
</code></pre>
<p>I don't understand why the output for the last cout is 1YYY if there are only three k_ pointers, and there's that 1 that's bothering me too.</p>

xhdpi is the largest density to date, right?
|
<p>There's no such density as "xxhdpi", right? (I know there's "xhdpi", of course). I've got a partner asking for assets in that density, but I cannot find any documentation on that. Have I missed this somehow? Is there a complete list of all known density names? I don't see anything in here, xhdpi is the largest mentioned:</p>

Avoid the jumping when sliding up or down (JQuery)
|
<p>I'm trying to get it so that upon clicking the pre-defined link, the content section will slide down and the other sections will slide up. I understand I could use JQuery callbacks for this, but for some reason, it always appears to try to slide the box up and then starts to bring it down (so it creates an odd jerky effect).</p>
<p>The JQuery can be seen here:</p>
<pre><code>$("#welcome_link").click(function () {
$("div[id$='_content']").slideUp('fast', function() {
$("#welcome_content").slideDown('fast');
});
});
</code></pre>
<p>Is there something I've done wrong here? I thought this would work.</p>
<p>Thanks!</p>

Best way of stopping java optimising away a method call when performance testing
|
<p>Im doing some performance optimising on some code, and I've got two ways of doing a calculation.</p>
<p>I've got a simple test harness:</p>
<pre><code> long start, end;
long oldDuration, newDuration;
int answer;
final int TEST_COUNT = 1000;
start = System.currentTimeMillis();
for(int i = 0 ; i < TEST_COUNT; i++)
{
answer = doCaluculationNewWay()
}
end = System.currentTimeMillis();
newDuration = end - start;
start = System.currentTimeMillis();
for(int i = 0 ; i < TEST_COUNT; i++)
{
answer = doCaluculationOldWay()
}
end = System.currentTimeMillis();
oldDuration = end - start;
</code></pre>
<p>How can I be sure that the JVM isnt just binning the call, knowing that the answer isnt being used?</p>
<p>I considered making answer volatile, but Im worried that it will impose an additional performance overhead due to memory synching issues.</p>

JQuery - Retrieve value from another child element of the same parent
|
<p>I'm fairly new to JQuery and am having trouble with something that I'm sure is simple. Here is an example of some html that I'm working with:</p>
<pre><code><tr>
<td><div class="testclass"><p>Test text</p></div></td>
<td><button class="testButton">Button text</button></td>
</tr>
</code></pre>
<p>When the button is clicked, I want to get the value in <code><p></code> in a previous cell. Here's how I'm currently trying to select it:</p>
<pre><code>var text = $(".testButton").parent().parent().closest('p').text();
</code></pre>
<p>Within the <code>onClick</code> function of the button, I've also tried:</p>
<pre><code>$(this).prev('p').text();
</code></pre>
<p>However, it's always <code>null</code>. I've messed around with jsfiddle for a little while trying to get this right, but no luck. Any tips would be appreciated.</p>

jQuery - hover function with two classes for an element, a hover for each class
|
<p>I'm not sure if this is a different problem embedded somewhere in my code, or an issue with the hover function i'm not aware of - </p>
<p>in short, i have an element with two classes</p>
<pre><code><input type="image" class="classA classB" ... />
</code></pre>
<p>and i have jQuery code like so:</p>
<pre><code>$('classA').hover(){
function1,
function2
}
$('classB').hover(){
function3,
function4
}
</code></pre>
<p>what i'm wanting is that when you hover over the input, BOTH hover functions (function1, function3) get fired. And when you move off it, BOTH functions (function2, function4) are also fired.
What appears to be happening is that the classB hover completely overrides or shadows or what have you the classA hover function. </p>
<p>Is this intended behaviour (or is this an indication that something is wrong with my much-larger code base?), and if so, what is the general consensus work around?</p>

Depth of testing?
|
<p>I have a fairly basic application. I'm loading it up on 2.1+ on emulators and 2.3.3 on an n1 and basically just making sure everything looks right and does what it's supposed to.</p>
<p>I was reading about activity testing on the dev site and it talks about creating test applications and such. I don't get the point of testing whether a textview = a resource string that you set it to or not.</p>
<p>How deep do you really need to test fairly basic apps before letting other people use them. Is there really anything that I won't catch using emulators and an n1 that test applications and such will?</p>

Receive an intent from a notification in an activity that's already open?
|
<p>I have an activity that creates notifications using the following code:</p>
<pre><code>Notification notification = new Notification(icon,
tickerText, 0);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
Context context = getApplicationContext();
CharSequence contentText = getString(R.string.subtitle);
Intent notificationIntent = new Intent(getBaseContext(),
MainActivity.class);
notificationIntent.putExtra("num", Integer.toString(i));
Intent deleteIntent = new Intent(getBaseContext(),
DeleteActivity.class);
deleteIntent.putExtra("num", Integer.toString(i));
PendingIntent contentIntent = PendingIntent.getActivity(
getBaseContext(), ran, notificationIntent, 0);
PendingIntent deletePendingIntent = PendingIntent
.getActivity(getBaseContext(), ran, deleteIntent, 0);
notification.setLatestEventInfo(context, text, contentText,
contentIntent);
notification.deleteIntent = deletePendingIntent;
final int NOTIF_ID = ran;
mNotificationManager.notify(NOTIF_ID, notification);
</code></pre>
<p>I keep a list of all the notifications from my app that are currently showing. </p>
<p>When the notification is clicked, it opens the MainActivity. I have some code in the onResume() to delete the notification from the list. This works fine.</p>
<p>When the notification is dismissed, it triggers DeleteActivity, which also deletes it from my list. This also works fine. </p>
<p>The problem is, if MainActivity is already open, and the notification is clicked, the onResume() doesn't run again, and so the notification is gone, but it's not deleted from the list of notifications that the app thinks are showing. </p>
<p>I'm wondering if there's any way I can execute a particular piece of code (or even just restart the whole activity) when the intent is received. I know I could just set it to use DeleteActivity instead but I'd rather have it open the MainActivity.</p>

How to prevent DOS attacks using image resizing in an ASP.NET application?
|
<p>I'm currently developing a site where users can upload images to use as avatars, I know this makes me sound a little paranoid but I was wondering what if a malicious user uploads an image with incredibly large dimensions that will eat the server memory (as a DOS attack), I already have a limit on the file size that can be uploaded (250 k) but even that size can allow for an image with incredibly large dimensions if the image for example is a JPEG that contains one color and created with a very low quality setting. Taking into consideration that the image is uploaded as a bitmap in memory when being resized (ie. not compressed), I wonder if such DOS attacks occur, even to check the image dimensions it has to be uploaded in memory first, did you hear about any attacks that exploited this? Am I too worried?</p>

Two dimensional associative array in PHP
|
<p>In my code I'm getting data (three columns) from a sql db and I want to store the rows in an associative PHP array. The array must be multi-dimensional because I want to use the row id from the database as a key so that i can fetch values like this:</p>

<p>$products["f84jjg"]["name"]</p>
<p>$products["245"]["code"]</p>
</blockquote>

{
$products = array($row[0] => array(
name => $row[1],
code => $row[2]
)
);
}

<p>Also, how should I reference the key if it is taken from a variable? What I want to do is:</p>
<pre><code>$productName = $products[$thisProd]["name"];

Aliasing the jQuery Namespace
|
<p>According to jQuery online document, if we want to avoid naming conflict, we could write our script like the followings: </p>
<pre><code>jQuery(document).ready(function($) {
// Code using $ as usual goes here.
});
</code></pre>
<p>While I feel the following approach much easier to understand:</p>
<pre><code>(function($){ //function to create private scope with $ parameter
//private scope and using $ without worry of conflict
})(jQuery); //invoke nameless function and pass it the jQuery object
</code></pre>
<p>The first approach seems harder for me to consume. My guess here is (with the first approach) that later on the anonymous function will be called behind the scene which will take <strong>jQuery</strong> as its parameter.</p>
<p>However I am not sure if my thinking is right. Could some one help me with it?
Thank you.</p>

Change default java installation
|
<p>I have many Java versions installed on a Windows 7 machine. Some of them are 32 bits, some are 64 bits. Now as default it starts one of those last versions (1.7 64 bits). How do I tell my Windows 7 machine to use another version of Java? One of the reasons is that I'm developing a JNI project from Microsoft Visual Studio C++ - it uses also java 1.7 64 bits.</p>
<p>Best regards,
Andrej</p>
<p>I have set: </p>
<p>User variable:
JAVA_HOME=C:\j2sdk1.4.2_04
PATH=%JAVA_HOME%\bin;%PATH%</p>
<p>and system variable:
JAVA_HOME=C:\j2sdk1.4.2_04
PATH=...a_lot_of_paths...;%JAVA_HOME%\bin;%PATH%</p>
<p>I had no idea which is better to set - for user or system settings. Done both.</p>
<p>System restart.</p>
<p>And...it didn't helped :(
When I run "java -version" from cmd i have java 1.7, but not java 1.4 like defined in PATH.</p>
<p>after run C:>where java
I got two results:</p>
<p>C:\Windows\System32\java.exe
C:\j2sdk1.4.2_04\bin\java.exe</p>
<p>Who let Java go to my windows directory ???!!! </p>
<p>How to deal with that?</p>

I tried to forward a method to super, but it occasionally doesn't work. Why?
|
<p>This is the code in question, simplified for this example:</p>
<pre><code>/** A version of Hashtable that lets you do
* table.put("dog", "canine");, and then have
* table.get("dogs") return "canine". **/
public class HashtableWithPlurals extends Hashtable {
/** Make the table map both key and key + "s" to value. **/
public Object put(Object key, Object value) {
super.put(key + "s", value);
return super.put(key, value);
}
}
</code></pre>

How to enable XDebug extension on my php?
|
<p>I am running php on a macbook pro running mountain lion.
Mountain lion comes with XDebug pre-installed, so based on a tutorial I've found , I made three steps.
First I've uncomment this line in my php.ini :</p>
<pre><code>zend_extension="/usr/lib/php/extensions/no-debug-non-zts-20090626/xdebug.so"
</code></pre>
<p>Secondly I've uncomment this line in my php.ini :</p>
<pre><code>xdebug.remote_enable=1
</code></pre>
<p>And finally I restarted the apache server with :</p>
<pre><code>sudo apachectl restart
</code></pre>
<p>The problem is that I see no xdebug appearing in my php details when I run a phpinfo().
Thank you.</p>
<p>PS : The path of the above xdebug.so file is correct.</p>
