Exception in thread "AWT-EventQueue-0" java.lang.ExceptionInInitializerError on object initialization
|
<p>I have an instance variable, like so:</p>
<pre><code>PathFinder finder;
</code></pre>
<p>(this is using Kevin Glass' A* tutorial, so the PathFinder class is in the same file, link here: <a href="http://cokeandcode.com/index.html?page=tutorials/tilemap2" rel="nofollow">http://cokeandcode.com/index.html?page=tutorials/tilemap2</a>)</p>
<p>Anyways, when I do</p>
<pre><code>finder = new AStarPathFinder(currentMap, 1000, true);
</code></pre>
<p>I get a Exception in thread ""AWT-EventQueue-0" java.lang.ExceptionInInitializerError".</p>
<p>currentMap is an instance of my Map class, and yes it is initialized. 1000 represents the maximum tile distance that will be searched, and the boolean represents diagonal movement true/false. Oh well I'll just throw the constructor at you:</p>
<pre><code>public AStarPathFinder(TileBasedMap map, int maxSearchDistance, boolean allowDiagMovement) {
this(map, maxSearchDistance, allowDiagMovement, new ClosestHeuristic());
}
</code></pre>
<p>I know it has something to do with static initializers, but I'm not too sure what else. Oh, and I tried to initialize an instance of the same AStarPathFinder class in another class, and I got the same result.</p>

Is it valid, to use std::string to hold binary data, to avoid manual dynamic memory management
|
<p>Pay attention to <code>base64_decode</code> in <a href="http://www.adp-gmbh.ch/cpp/common/base64.html" rel="nofollow">http://www.adp-gmbh.ch/cpp/common/base64.html</a></p>
<pre><code>std::string base64_decode(std::string const& encoded_string)
</code></pre>
<p>The function is suppose to return <code>byte array</code> to indicate binary data. However, the function is returning <code>std::string</code>. My guess is that, the author is trying to avoid from perform explicit dynamic memory allocation.</p>
<p>I try to verify the output is correct.</p>
<pre><code>int main()
{
unsigned char data[3];
data[0] = 0; data[1] = 1; data[2] = 2;
std::string encoded_string = base64_encode(data, 3);
// AAEC
std::cout << encoded_string << std::endl;
std::string decoded_string = base64_decode(encoded_string);
for (int i = 0; i < decoded_string.length(); i++) {
// 0, 1, 2
std::cout << (int)decoded_string.data()[i] << ", ";
}
std::cout << std::endl;
getchar();
}
</code></pre>
<p><strong>The decoded output is correct. Just want to confirm, is it valid to <code>std::string</code> to hold binary data, to avoid manual dynamic memory management.</strong></p>
<pre><code>std::string s;
s += (char)0;
// s.length() will return 1.

Most efficient way to store a 40 cards deck
|
<p>I'm building a simulator for a 40 card's deck game. The deck is divided into 4 seeds, each one with 10 cards. Since there's only 1 seed that's different from the others ( let's say, hearts ) , I've thinked of a quite convinient way to store a set of 4 cards with the same value in 3 bits: the first two indicate how many cards of a given value are left, and the last one is a marker that tells if the heart card of that value is still in the deck.
So,</p>
<p><strong>{7h 7c 7s} = 101</strong></p>
<p>That allows me to store the whole deck on 30 bits of memory instead of 40. Now, when i was programming in C, I'd have allocated 4 chars ( 1 byte each = 32 bits), and played with the values with bit operations.
In C# I can't do that, since chars are 2 bytes each and playing with bits is much more of a pain, so, the question is : what's the smallest amount of memory I'll have to use to store the data required?</p>
<p>PS: Keep in mind that i may have to allocate 100k+ of those decks in system's memory, so saving 10 bits is quite a lot</p>

Business logic of the CheckBox listener inside a ListView
|
<p>I have implemented a custom adapter for my ListView, that includes a CheckBox in each row.</p>
<p>As I have my click listener in my custom adapter, I'm forced to implement there my business logic (that is, what happens when a CheckBox is clicked... access the database, etc).</p>
<p>Is that correct? Wouldn't be a better practice to implement that business logic outside the custom adapter? (I think the adapter should only care about visualization).</p>

Passing Integer by reference with threads
|
<p>I have a class with a global variable, Integer clock, initialized to 0. It passes 'clock' to a few thread constructors, starting the threads also. It seems increments to 'clock' can be seen within the thread, but in their calling process, 'clock' is always 0. Because Integer is an object and objects are passed by reference, I would expect changes to 'clock' to be seen everywhere. Is this not the case?</p>

C# error handling (NaN)

<p>I have written simple math function plotter in C# using Patrick Lundin´s Math free parser.</p>
<p>Now, my code snippet is this: </p>
<pre><code>for (float value = -xaxis; value < xaxis; value += konst)
{
hash.Add("x", value.ToString());
double result = 0;
result = parser.Parse(func, hash);...
</code></pre>
<p>This works perfectly for functions defined on real numbers. But, when I want want to parse functions defined only on R+ for example, ln(x), naturally parser gives NaN into result.</p>
<p>Now, I tried to handle it thru exception handling, like so:</p>
<pre><code>for (float value = -xaxis; value < xaxis; value += konst)
{
hash.Add("x", value.ToString());
double result = 0;
try{
result = parser.Parse(func, hash);
}
catch {
count = false; //just a variable I am using to draw lines
continue; // I hoped to skip the "wrong" number parsed until I came to R+ numbers
}...
</code></pre>
<p>But this doesen´t work, while debugging, catch is not executed at all.</p>

Create dynamic button with dynamic text
|
<p>I have a project where I need to create menu buttons from a list in SQL Server. The problem I am having is that I need to add code to the text of those buttons. So there would be a birthday button and it should display the number of birthdays within the next two weeks or a button with the number of upcoming events. Any thoughts on how best to do this? Thanks.</p>
<p>Wade</p>
<p>Clarification:</p>
<p>There is no code yet, just some requirements. What I am doing is querying a table to get the list of buttons to display. Now each of these buttons may have dynamic text, for things like count of birthdays, events,etc... I am trying to see what the best way would be to handle this. Should I embed a snippet of code to go along with the menu item to execute when I iterate over the menu items? Maybe I should build a javascript file to go along with the code, which I add code to query a service for certain menu items? Thanks for any help.</p>

Making a table row animate upward movement in sortable UI
|
<p>I'm using Sortable jQuery UI to allow users to drag and drop table rows. This allows users to rank items in a table based on their preference. Once a user has finished ordering his list, they press a save button which executes an Ajax call. The new rank is saved into the database and the table highlights briefly.</p>
<p>I have now added an additional button that will send an item straight to the top of the list. It's also ajax. It works very well except that I would like to add a transition effect where by the <code><tr></code> will break away and drag itself to the top of the table, and push the following rows down. Is this possible? Here is the code I'm using:</p>
<p>This code handles the call to save changes to the database from the "drag-and-drop" feature:</p>
<pre><code><input type="button" value="Save Queue" id="saveButton" class="list-button">
$(document).ready(function(){
$("#sortable").sortable();
$("#saveButton").click(persist);
});
// Persist function (save order)
function persist() {
var data = $("#sortable").sortable('toArray');
$.ajax({
traditional: true,
url: "/gz/index.cfm/membros/rankListByAjax?order="+data,
type: "POST",
success: function(msg){
$("#sortable tr").effect("highlight", {}, 1000);
}
});
}
</code></pre>
<p>The following code is the new "send-item-to-top" button I added. This is when I would like the transition to happen:</p>
<pre><code><form ...onsubmit="

Sorting and reinserting elements removes bound functions
|
<p>I need to sort some rows after they've been inserted. What I'm doing now is:</p>
<pre><code>var $r = $tbody.find('tr').sort(function(a,b) {
return compare(taxstatusOf(a), taxstatusOf(b));
});
$tbody.empty().append($r);
</code></pre>
<p>This works, <em>except</em> that functions that were bound to elements contained in the rows are no longer bound (or no longer fire, which amounts to the same thing).</p>
<p>So, is there a right way to sort rows that doing fail like this? Do I have to re-bind?</p>

Best language tooling
|
<p>I was listening to a podcast recently (may have been SO - can't remember) when the interviewee said that one of the reasons Java was so successful and popular was the tooling.</p>
<p>Having use of great FOSS editors such as Eclipse, NetBeans. Metrics tools such as Cobertura, Find Bugs, Build tools such as Maven and ANT.. I'd have to agree</p>
<p>I've done a fair bit of .NET and the tools are OKish. The problem seems to be that there isn't the depth in tooling that there is in Java. The FOSS stuff seems pretty limited. </p>
<p>My question: Are there any modern languages with a better community and tooling for getting the job done? </p>

<p>I have a project in Java I am running that uses an external JAR file.</p>

borrowing costructors and prototype chain
|
<p>in many books and online tutorial there are examples on passing data to a super-class
constructor via a borrowing method pattern:</p>
<pre><code>var Parent = function(name)
{
this.name = name;
this.my_parent = "parent_property";
this.go = function()
{
alert("GO")
}
}
var Child = function(name)
{
this.name = name;
this.my_child = "child_property";
Parent.call(this);
alert(this.hasOwnProperty("go")) // HERE TRUE!!!
}
var ChildChild = function(name)
{
this.name = name;
this.su = function(){}
}
// PSEUDO CLASSICAL ECMA STANDARD
Child.prototype = new Parent("PARENT");
ChildChild.prototype = new Child("CHILD");
var c = new ChildChild("CHILDCHILD");
</code></pre>
<p>now my question is: is this correct? in that pattern the properties of the super-class
are copied into THIS but in a OOP system I think that those properties must be in its
super-class. Now BORROWING constructor is only another pattern to make a sort of inheritance so I could not use prototype and so all the chain superclass properties are
into the last child class...but I don't think it's efficient.</p>
<p>So, at end, how can I pass data to a super-class without that pattern?</p>
<p>Thanks</p>

How to setup Math program
|
<p>I'm needing to write a program (C#) that will allow the user to create generic formulas with variables and numbers. For example:</p>
<pre><code>D = A + (A - C / X)(7.8 - 6.6)
F = E + (E - C / X)(7.8 - 6.6)
FinalResult = (A + D)(0.9) + (E + F)(0.32) + B(0.1) + .023
</code></pre>
<p>where all variables would mean for me to go to a database and look something up based on values and return a number in its place. So A would be 2.12 for example (and the same for C and E)</p>
<p>Whats the best way to structure this program? How would I make my program read these formulas?</p>
<p>I've seen a little bit of the MathML but not sure how to get that started (or an example of it)</p>
<p>--Update--</p>
<p>I mentioned MathML just seeing some other questions involving it on SO. Y'all are correct, I'm not needing to display it, I'm just needing to identify what someone wants and use that to calculate something.</p>
<p>My variables will map to something in a database. For example, A would tell me to use the following:</p>
<pre><code>Vend_Key = 3
Trmnl_Key = 5
Prod_Key = 7
</code></pre>
<p>which would then be used to return a number from a database.</p>
<p>I'm going to need a database to save the formula's that people create. I'll have to have a scheduled task that can run and execute these functions and save the information somewhere else.</p>

Changing Base Path In PHP
|
<p>I need to change the folder that "relative include paths" are based on.</p>
<p>I might currently be "in" this folder:
C:\ABC\XYZ\123\ZZZ</p>
<p>And in this case, the path "../../Source/SomeCode.php" would actually be in this folder:
C:\ABC\XYZ\Source</p>
<p>And realpath('.') would = 'C:\ABC\XYZ\123\ZZZ';</p>
<p>If however, realpath('.') were "C:\Some\Other\Folder"</p>
<p>Then in this case, the path "../../Source/SomeCode.php" would actually be in this folder:
C:\Some\Source</p>
<p>How do I change what folder is represented by '.' in realpath()?</p>
<p>Like this:</p>
<pre><code>echo ('BEFORE = '.realpath('.')); // BEFORE = C:\ABC\XYZ\123\ZZZ
// Some PHP code here...
echo ('AFTER = '.realpath('.')); // AFTER = C:\Some\Other\Folder
</code></pre>

Hidden Field being set with data from another website
|
<p>I have a very interesting situation and I'm just looking for ideas at the moment. I have a webpage for insurance agents that the agent will login and then enter some insured information. </p>
<p>There is a field named "agentnumber" that is on the form, but is hidden by a display:none. The field is set from the username of the person who logs in whenever the form loads the first time. The form will save automatically when the user leaves the page. </p>
<p>I am experiencing a weird issue that every now and then, the agentnumber field is getting saved with incorrect data. After discussing it with the agent, it is being saved with the agentnumber of the agent from other companies, not from the my website. Just looking for any ideas on what may be happening as I thought browser security would prevent cross site javascript. The users are using IE 7 & IE 8. Any help would be appreciated as I'm not even sure what to look for.</p>

Website is freezing and cant login to cpanel

It was working great on my local server but when I put it up on an actual server it started running really slow until it finally gave up and now I can't even access the website.. or cpanel... I have been doing a little research thinking maybe it had to do with and overload of sql queries but I can't seem to find any... </p>
<p>My site contains a lot of javascript and ajax calls to php scripts which fetch data from the database... (new notifications, messages) and I have stuff like:</p>

}
});
$r = setTimeout(alive_retrieval,100);
}
$(function(){
$t = setTimeout(question_retrieval,100);
});
</code></pre>
<p>This just keeps calling the alive_retrieval function over and over, which I am guessing could cause my site to be slow...</p>
<p>I don't kno what to post in order to help (code, the link to my website.. or w/e) Please tell me what I should give you guys so you might be able to see what is happening...</p>

Supporting multiple screen sizes with Android using ImageButtons
|
<p>I've read the Android documentation:
<a href="http://developer.android.com/guide/practices/screens_support.html" rel="nofollow">http://developer.android.com/guide/practices/screens_support.html</a>
but still have some questions.</p>
<p>I'm trying to design a music application which basically has images of the instrument (ImageButton) that play a sound when clicked. However, I'm confused about how to have the ImageButtons scale to fit all the different screen sizes and how to position them.</p>
<ol>
<li><p>Which layout is best used for needing to position ImageButtons in specific locations on the screen? (i.e. cymbals on a drum set) FrameLayout, RelativeLayout?</p></li>
<li><p>If I only really care about medium and large screens, do I need to create different resources (images) for both as well as a different XML layout to position them?</p></li>
</ol>
<p>I'm trying to find the simplest way to do this without having to create a separate layout XML file for positioning/size and separate image resources for each screen.</p>
<p>Any guidance is greatly appreciated. Thanks!</p>

Reasons for C++ Prototyping
|
<p>I'm a beginning programmer, trying to get a grasp on everything, so pardon the probably mundane theoretical question:</p>
<p>I see in a C++ tutorial that prototyping is needed to let the compiler know that a function(?) is coming up and not to throw up any errors. Why does it not search throughout a document to find the function it's looking for?</p>
<p>Maybe the question I'm asking is; what is the purpose for prototyping? And can it be used in other languages?</p>

<p>I am using jcreator to practice java language. I came up with a conditional statement in which if the user input is = "test" it will print an "okay!" message. This is my code: </p>
<pre><code>class conditional {
public static void main (String[] args) {
Scanner user_input = new Scanner(System.in);
String username;
System.out.print("username: ");
username = user_input.next();
if (username == "test") {
System.out.println("okay");
}
else {
System.out.println("not okay");
}
}
</code></pre>
<p>The above code does not show any error, it does not display the "okay" && "not okay" message either. I am not sure what's wrong with my logic.</p>

Accessing object's property inside generic method
|
<p>How can access the property of an object inside generic method?<br>
I can't use <code>where T: A</code> because this method will receive different objects, but all objects have a common property to work on.<br>
(I also can't make for them a common interface) </p>
<pre><code>public class A
{
public int Number {get;set;}
}
List<A> listA = new List<A>{
new A {Number =4},
new A {Number =1},
new A {Number =5}
};
Work<A>(listA);
public static void Work<T>(List<T> list1)
{
foreach(T item in list1)
{
do something with item.Number;
}
}
</code></pre>
<p>An update: I need also to set the property</p>

calculating factorials in C#

<p>I am trying to write a program that will take the users input value and asks whether they want to calculate the value of the numbers 1 to n or the factorial of n!

Getting specific table row based on id mysql DB
|
<p>I have a database where I view all the records, the last column is the table ID, I click it and I want to be able to edit that rows data only, here's what I got but it doesn't waork after updating phpmyadmin:::</p>
<pre><code> <?php
include "db.inc.php";
$id=$_GET['id'];
$order = "SELECT * FROM ircb where id='$id'";
$result = mysql_query($order);
$row = mysql_fetch_array($result);

<td>
<input type="text" name="item"
value="<? echo "$row[item]"?>" size="30" style="color: black;background-color:#FFFF11">
</td>
</tr>
</code></pre>
<p>I end up getting no results returned, when I hover over the link it does display the correct table row id but when I click the link I get empty boxes containing some of the code like <code><? echo</code> in the fields..no true values though..and the page header after clicking the link does show ::: ...../edit_form.php?id=8 for row 8 so I assume something in my query is not quite right.

Sorting a dictionary by value then by key
|
<p>This seems like it has to be a dupe but my SO-searching-fu is poor today...</p>
<p>Say I have a dictionary of integer key/values, how can I sort the dictionary by the values descending, then by the key descending (for common values).</p>
<p>Input:</p>
<pre><code>{12:2, 9:1, 14:2}
{100:1, 90:4, 99:3, 92:1, 101:1}
</code></pre>
<p>Output:</p>
<pre><code>[(14,2), (12,2), (9,1)] # output from print
[(90,4), (99,3), (101,1), (100,1), (92,1)]

Python element-wise in-place addition
|
<p>Here is the scenario: given <em>n</em> lists (of identical length) of integers and an accumulator (of the same length, indeed), accumulate the element-wise sum, in-place. The in-place constraint is here because I accumulate values in a dict of lists (hum ... quite not clear, see the example below)</p>
<p><strong>EDIT</strong>: I'm looking for a solution that does not involve numpy</p>
<pre><code># My lists are long (they are actually pixels in 1000x1000 images)
# but I keep l low for the sake of the example
l = 5
# Values here are arbitrary and won't be repeated in the real word
# e.g. list 1 might be [41,15,0,2,3], etc.
lists = [
{'id': 1, 'values': [12]*l},
{'id': 2, 'values': [42]*l},
{'id': 2, 'values': [25]*l},
{'id': 1, 'values': [6]*l},
]
maps = {
1: [0]*l,
2: [0]*l
}
for item in lists:
# Get the "target" for this list
target = maps[item['id']]
# Element-wise addition of item['values'] to target here!
# This won't work
target = map(lambda x,y:x+y, target, item['values'])
# This neither
target = [(x+y) for x,y in itertools.izip(target,item['values'])]
# For either of the previous to work, I need to re-assign
# the result to 'target', like so
maps[item['id']] = target
</code></pre>
<p>While it works and I can professionally live with it, I personally can't.</p>

How are Messengers garbage collected?
|
<p>Consider this code:</p>
<pre><code>Message message = Message.obtain(null, MSG_REQUEST_QUOTE, symbol);
message.replyTo = new Messenger(new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case StockMessengerService.MSG_QUOTE_VALUE:
callback.onQuote(symbol, msg.arg1);
break;
case StockMessengerService.MSG_QUOTE_FAILURE:
callback.onFailure(symbol, msg.obj.toString());
break;
default:
super.handleMessage(msg);
}
}
});
mService.send(message);
</code></pre>
<p>How is the JVM able to garbage collect the replyTo Messenger? In the Android javadocs, they only have a single Messenger, bound to the Activity. But this code works, but I'm quite curious how it is the JVM doesn't GC the Messenger before it gets its message, OR, whether this code is quite risky and will leak memory?</p>
<p>Edit2:
mService is like:</p>
<pre><code>private ServiceConnection mConnection = new ServiceConnection() {
public void onServiceConnected(ComponentName className, IBinder service) {
mService = new Messenger(service);
</code></pre>
<p>This is based on the sample code in the Service javadoc at <a href="http://developer.android.com/reference/android/app/Service.html" rel="nofollow">http://developer.android.com/reference/android/app/Service.html</a></p>

<p>My question is, when I create an Android in Eclipse, which SDK should I choose? My initial thought is to write with 2.3.3 SDK. I imagine I should be able to run it on honeycomb as well, or I will have to write the same app but using the 3.0 SDK?</p>

A way to pass a variable into a nested function

<p>Is there a way i can pass information into a nested function ? The problem is i want to use jQuery to animate an object being removed and then after have it remove the object from the dom. But theres no way to pass information into the nested function. I first though the bellow would work but no luck,</p>
<pre><code>tab = this.tab //this.tab is a dom element
$(this.tab).effect('drop',null,null, function(tab)
{
$(tab).remove()
})
</code></pre>
<p>People have suggested that i store the element in a global put this function is part of a class and there can be many objects which may call this function at the same time.</p>

Force superscripts for operators in jqMath
|
<p>I am using jqMath to display chemistry formulas on a website. I need to be able to display charges as superscripts (i.e., positive + and negative charges -). It seems like jqMath (or maybe MathML) hardcodes all math operators to display as normal size. I've tested this with +, -, =, and % signs and none will display as superscripts (tested here: <a href="http://mathscribe.com/author/jqmath.html" rel="nofollow">http://mathscribe.com/author/jqmath.html</a>). Note that </p>
<pre><code><sup></sup>
</code></pre>
<p>is not valid markup when using jqMath; the ^ precedes any character to be superscripted. </p>
<p>Has anyone found a way around this? </p>

Is using menuItem.getItemId() valid in finding which MenuItem is selected by user?
|
<p>I have menu in my App. I need to check for the which menu item been selected by the user and take appropriate action. I did this as,</p>
<pre><code> @Override
public boolean onOptionsItemSelected(MenuItem menuitem){
String title = menuitem.getTitle().toString();
int itemId = menuitem.getItemId();
switch(itemId){
case 2131296257:
-----------------;
break;
case 2131296258:
------------------;
break;
}
</code></pre>
<p>But these MenuItem Id's are getting changed each time I run my App. Now I thought to compare the menuTitle with hard coded string values like ,</p>
<pre><code> String title = menuitem.getTitle().toString();
if(title.equals("Settings..")){
-------------
-------------
-------------
}
</code></pre>
<p>But I don't think it's a good practice. But I guess I can do the same using the menu titles defined in strings.xml. But I am not sure how to use this.... (like R.string.....).</p>
<p>Can someone suggest on this please.</p>
<p>Thanks</p>

Once control reaches class C , Audio is played. But when Backkey is pressed Audio doesnot stop it continuous to play. How can I make the Audio to stop when BackKey is pressed.
