• JVM terminated. Exit code = -1

  - by Lex

  Hello, I've been using Eclipse for some time already, and I didn't have any problems with it. However, when I tried to generate some javadoc, I found that I didn't have the SDK installed. I installed jdk 6u23, and from then on, Eclipse hasn't been working. At first it told me it couldn't find a JRE/SDK. After copying and placing the JRE in the Eclipse folder, the error changed to this: http://i258.photobucket.com/albums/hh261/magical_7/Eclipse.png I've searched around for some solutions, and found a few of varying nature. However, none of them seemed to work. I've tried emptying my eclipse.ini file without success. Altering some values in eclipse.ini didn't work either. Installing Java SDK 1.5 didn't work. Does anyone have other possible solutions? Update: I tried reinstalling Eclipse, but it didn't fix the problem. I did notice that it's a 32bit version, while I'm running a 64bit system. However, if this were to be the problem, I find it strange that it hasn't been an issue earlier.

• Layout question with BlackBerry IDE FieldManagers; how to emulate HTML's rowspan

  - by canadiancreed

  Hello all I'm trying to create a page where a list of items are displayed in a row where there are multiple columns on the left, but only one on the right, encased within a horizontialFieldManager. Currently I have the following code to attempt to do the following: VerticalFieldManager mainScreenManager = new VerticalFieldManager(); mainScreenManager.add(titleField); for (int i = 0; i < 10; i++) { HorizontalFieldManager itemAreaManager = new HorizontalFieldManager(); VerticalFieldManager itemTextFieldsAreaManager = new VerticalFieldManager(); itemTextFieldsAreaManager.add(new RichTextField(contentArticleTitle[i])); itemTextFieldsAreaManager.add(new RichTextField(contentArticleDate[i])); itemTextFieldsAreaManager.add(new SeparatorField()); itemAreaManager.add(itemTextFieldsAreaManager); itemAreaManager.add(new ButtonField("", 0)); mainScreenManager.add(itemAreaManager); }; add(mainScreenManager); Now the issue I'm experiencing is probably obvious to those familiar with managers; the horizontialFieldManager has the first item added to it consuming the entire width available, thereby never showing the button. What I'm wondering is how can I tell this in an extended class to only take up a certain percentage of the available width? I've tried subLayout and setting the width to be a certain amount, but it will just show the button instead of the text (pretty much same problem, just reversed)

• C++ bughunt - High-score insertion in a vector crashes the program

  - by Francisco P.

  Hello, everyone! I have a game I'm working on. My players are stored in a vector, and, at the end of the game, the game crashes when trying to insert the high-scores in the correct positions. Here's what I have (please ignore the portuguese comments, the code is pretty straightforward :P): //TOTAL_HIGHSCORES is the max. number of hiscores that i'm willing to store. This is set as 10. bool Game::updateHiScores() { bool stopIterating; bool scoresChanged = false; //Se ainda nao existirem TOTAL_HISCORES melhores pontuacoes ou se a pontuacao for melhor que uma das existentes for (size_t i = 0; i < players.size(); ++i) { //&& !(players[i].isAI()) if (players[i].getScoreValue() > 0 && (hiScores.size() < TOTAL_HISCORES || hiScores.back() < players[i].getScore())) { scoresChanged = true; if(hiScores.empty() || hiScores.back() >= players[i].getScore()) hiScores.push_back(players[i].getScore()); else { //Ciclo que encontra e insere a pontuacao no lugar desejado stopIterating = false; for(vector<Score>::iterator it = hiScores.begin(); it < hiScores.end() && !(stopIterating); ++it) { if(*it <= players[i].getScore()) { //E inserida na posicao 'it' o Score correspondente hiScores.insert(it, players[i].getScore()); //Verifica se o comprimento do vector esta dentro do desejado, se nao estiver, este e rectificado if (hiScores.size() > TOTAL_HISCORES) hiScores.pop_back(); stopIterating = true; } } } } } if (scoresChanged) sort(hiScores.begin(), hiScores.end(), higher); return scoresChanged; } What am I doing wrong here? Thanks for your time, fellas.

• [PHP] Local/Dev/Live deployment - best workflow

  - by Adam Kiss

  Hello, situation We our little company with 3 people, each has a localhost webserver and most projects (previous and current) are on one PC network shared disk. We have virtual server, where some of our clients' sites and our site. Our standard workflow is: Coder PC ? Programmer localhost ? dev domain (client.company.com) ? live version (client.com) It often happens, that there are two or three guys working on same projects at the same time - one is on dev version, two are on localhost. When finished, we try to synchronize the files on dev version and ideally not to mess up any files, which *knock knock * doesn't happen often. And then one of us deploys dev version on live webserver. question we are looking for a way to simplify this workflow while updating websites - ideally some sort of diff uploader or VCS probably (Git/SVN/VCS/...), but we are not completely sure where to begin or what way would be ideal, therefore I ask you, fellow stackoverflowers for your experience with website / application deployment and recommended workflow. We probably will also need to use Mac in process, so if it won't be a problem, that would be even better. Thank you

• Very simple code for number search gives me infinite loop

  - by Joshua

  Hello, I am a newbie Computer Science high school student and I have trouble with a small snippet of code. Basically, my code should perform a basic CLI search in an array of integers. However, what happens is I get what appears to be an infinite loop (BlueJ, the compiler I'm using, gets stuck and I have to reset the machine). I have set break points but I still don't quite get the problem...(I don't even understand most of the things that it tells me) Here's the offending code (assume that "ArrayUtil" works, because it does): import java.util.Scanner; public class intSearch { public static void main(String[] args) { search(); } public static void search() { int[] randomArray = ArrayUtil.randomIntArray(20, 100); Scanner searchInput = new Scanner(System.in); int searchInt = searchInput.nextInt(); if (findNumber(randomArray, searchInt) == -1) { System.out.println("Error"); }else System.out.println("Searched Number: " + findNumber(randomArray, searchInt)); } private static int findNumber(int[] searchedArray, int searchTerm) { for (int i = 0; searchedArray[i] == searchTerm && i < searchedArray.length; i++) { return i; } return -1; } } This has been bugging me for some time now...please help me identify the problem!

• Chrome + jQuery hide/show inline

  Hello I have these things <ul class="ul_std" style="float:right"> <li class="action_buttons" ><a id="button_deleteNormal" class="button_small button_small_red" >??a??af?</a></li> <li class="action_buttons"><a id="button_editCancel" class="button_small" >?????s? ???p?p???s??</a></li> <li class="action_buttons"><a id="button_editNormal" class="button_small" >???p?p???s?</a></li> <li class="action_buttons" style="margin-right:0" ><a id="button_addNormal" class="button_small">???s????</a></li> </ul> The problem is that i hide all of them except the anchor with id = button_addNormal at $(document).ready()... Everything works fine but at chrome when i want to show them ,it displays them as display:inline and not as display:inline-block ... The css class button_small have display:inline-block.... Firefox,IE 6+ works ok... Havent tested on safari but i hope that it would be ok... Why chrome kills inline-block? The solution was to put .css("display","inline-block") instead of .show()

• Writing a program which uses voice recogniton... where should I start?

  - by Katsideswide

  Hello! I'm a design student currently dabbling with Arduino code (based on c/c++) and flash AS3. What I want to do is to be able to write a program with a voice control input. So, program prompts user to spell a word. The user spells out the word. The program recognizes if this is right, adds one to a score if it's correct, and corrects the user if it's wrong. So I'm seeing a big list of words, each with an audio file of the word being read out, with the voice recognition part checking to see if the reply matches the input. Ideally i'd like to be able to interface this with an Arduino microcontroller so that a physical output with a motor could be achieved in reaction also. Thing is i'm not sure if I can make this program in flash, in Processing (associated with arduino) or if I need another CS3 program-making-program. I guess I need to download a good voice recognizing program, but how can I interface this with anything else? Also, I'm on a mac. (not sure if this makes a difference) I apologize for my cluelessness, any hints would be great! -Susan

• Using functions and arrays

  - by Ordo

  Hello! My little program below shall take 5 numbers from the user, store them into an array of integers and use a function to print them out. Sincerly it doesn't work and my output is always "00000". I can't find a mistake, so i would be glad about any advice. Thanks. #include <stdio.h> void printarray(int intarray[], int n) { int i; for(i = 0; i < n; i ++) { printf("%d", intarray[i]); } } int main () { const int n = 5; int temp = 0; int i; int intarray [n]; char check; printf("Please type in your numbers!\n"); for(i = 0; i < n; i ++) { printf(""); scanf("&d", &temp); intarray[i] = temp; getchar(); getchar(); } printf("Do you want to print them out? (yes/no): "); scanf("%c", &check); if (check == 'y') printarray(intarray, n); getchar(); getchar(); return 0; }

• Jquery (non-gem) plugin won't work in my rails 3.2 app

  - by jfdimark

  I'm trying to equalize columns in my rails 3.2 app, and while there may be a better way to do it then my current attempt, after hours of trying to make it work I'd like to see if anyone can point out specifically why this jQuery plugin (which isn't a gem) is not working. I'm not getting any errors in the developer console, so it's hard to pin point. Here's the relevant code: The index view, where I've followed the plugin's instructions: div id="column-group"> <div class="equalize span5 offset1 UserProfile"> <% if user_signed_in? %> <h3>Hello <%= current_user.name %>!</h3> </div> <div class="equalize span5 MemberDisplay"> My application.js file, where I've also included the specific js code, so it would definitely be picked up by the application: //= require jquery //= require jquery_ujs //= require bootstrap //= require equalize_column_heights //= require_tree . $(document).ready(function() { $("#column-group").equalize_column_heights("equalize"); }); The jQuery plugin code, which is saved in my vendor/assets/javascripts folder: (function ($) { $.fn.equalize_column_heights = function (equalize_class) { var tallest_column=0; parent_id = "column-group" + $(this).attr("id") + " ." + equalize_class; $(parent_id).each(function(index, value) { if (tallest_column < $(this).height()){ tallest_column = $(this).height(); } }); $(parent_id).each(function(index, value) { $(this).css({'min-height': tallest_column}); }); } }(jQuery)); I've read all the rails guides documentation on the asset pipeline and all the relevant jQuery-rails3 questions on SO, but after several hours, I just can't seem to figure this one out. If anyone can point to other tutorials on how to get non-gem jQuery plugins to work in a Rails 3.2 app then I'd be glad to take a look!

• Very fast document similarity

  - by peyton

  Hello, I am trying to determine document similarity between a single document and each of a large number of documents (n ~= 1 million) as quickly as possible. More specifically, the documents I'm comparing are e-mails; they are grouped (i.e., there are folders or tags) and I'd like to determine which group is most appropriate for a new e-mail. Fast performance is critical. My a priori assumption is that the cosine similarity between term vectors is appropriate for this application; please comment on whether this is a good measure to use or not! I have already taken into account the following possibilities for speeding up performance: Pre-normalize all the term vectors Calculate a term vector for each group (n ~= 10,000) rather than each e-mail (n ~= 1,000,000); this would probably be acceptable for my application, but if you can think of a reason not to do it, let me know! I have a few questions: If a new e-mail has a new term never before seen in any of the previous e-mails, does that mean I need to re-compute all of my term vectors? This seems expensive. Is there some clever way to only consider vectors which are likely to be close to the query document? Is there some way to be more frugal about the amount of memory I'm using for all these vectors? Thanks!

• Fade in an HTML element with raw javascript over 500 miliseconds.

  - by Juan C. Rois

  Hello everybody, Once again I find myself stuck by something that I just don't understand. Any help would be appreciated. I'm working on a modal window, you click something and the background is masked and a modal window shows some content. I have a div with "display:none" and "opacity:0", and when the user triggers the modal, this div will overlay everything and have certain transparency to it. In my mind, what I need to do is: Set the opacity Perform a "for" loop that will check if the opacity is less than the desired value. Inside this loop, perform a "setInterval" to gradually increment the value of the opacity until it reaches the desired value. When the desired value has been reached, perform an "if" statement to "clearInterval". My code so far is as follows: var showMask = document.getElementById('mask'); function fireModal(){ showMask.style.opacity = 0; showMask.style.display = 'block'; var getCurrentOpacity = showMask.style.opacity; var increaseOpacity = 0.02; var finalOpacity = 0.7; var intervalIncrement = 20; var timeLapse = 500; function fadeIn(){ for(var i = getCurrentOpacity; i < finalOpacity; i++){ setInterval(function(){ showMask.style.opacity = i; }, intervalIncrement) } if(getCurrentOpacity == finalOpacity){ clearInterval(); } } fadeIn(); } As you all can guess, this is not working, all it does is set the opacity to "1" without gradually fade it in. Thanks in advance for your help.

• [iPhone] Play video not in full screen mode

  - by Kyo

  Hello, First, excuse my english :) I've read on apple developer website that video playback provides by the framework supports only full screen mode. I will need to develop an application where video can be played in reduce screen mode. I've see that Orange TV make something which looks like what i need to do. http://img218.imageshack.us/img218/1228/tvplayerorange.jpg The application is available on app store but you need to have a subscription to test this application. Whatever, to resume it, we can see video (tv stream video) in a reduce mode and if we click on the screen it switch to a full screen mode. So my question, what i want to do is possible (Orange TV made it) but i wonder the difficulty to make it. It seems that I have to make a video player. If it take a bunch of time, I tkink I will use Media Player Framework of iPhone even isn't the optimal solution for me. Feel free to ask me more details ;) Thank you for your answers.

• Keeping the number of objects and event-listeners on stage as low as possible

  - by DevEight

  Hello. I am creating a site with lots of big scrollable text-boxes in it. Each text-box object contained some text, and two buttons to scroll up/down with. The scroll buttons each had an event listener so the text moved when you clicked them. These text-boxes were stacked on-top of each other with all except one having an alpha of 0. If I wanted to change which text-box is active I move it to the front and call a small TweenLite animation. To the left (outside of the text-box objects) I have an object similar to a menu. It also has about 12 or so event-listeners (one for every button). This turns out cause A LOT of lag an it's very troublesome for my laptop to run it. What I need help with doing is to reduce the number of event-listeners on the stage and also the amount of text-boxes. What I was thinking was to add the text-boxes using AS so I only have 1 on the stage at a time but I couldn't figure out how to do it. I also thought it might be better to just use 1 big event-listeners and from mouseX and mouseY decide which button the user is trying to push. Are there any better alternatives to this? And if so, please elaborate on how to do it.

• PHP: Problem with reading Files

  - by mathiregister

  hello guys, i wonder what i'm doing wrong! i want to read a folder and run through the existing files, checking if they are either images or textfiles. if there are textfiles they should be put into a div, if there are images the should be output as an image. <?php $path = 'thumbs'; if ($handle = opendir($path)) { while (false !== ($file = readdir($handle))) { $ext = pathinfo($file, PATHINFO_EXTENSION); if ($ext == "jpg" || $ext == "jpeg" || $ext == "gif" || $ext == "png") { print "<img class='thumb' src='$path/$file'/>"; } else if ($ext == "txt" || $ext == "rtf") { //read text $lines = file_get_contents($file); $lines = str_replace("\n","<br/>",$lines); print "<div class='text'>" . $lines .

• Python - Access a class from a list using a key

  - by Fake Name

  Is there any way to make a list of classes behave like a set in python? Basically, I'm working on a piece of software that does some involved string comparison, and I have a custom class for handling the strings. Therefore, there is an instance of the class for each string. As a result, I have a large list containing all these classes. I would like to be able to access them like list[key], where in this case, the key is a string the class is based off of. It seems to me that I sould be able to do this somewhat easily, by adding something like __cmp__ to the class, but either I'm being obtuse (likely), or Im missing someting in the docs. Basically, I want to be able to do something like this (Python prompt example): >>class a: ... def __init__(self, x): ... self.var = x ... >>> from test import a >>> cl = set([a("Hello"), a("World"), a("Pie")]) >>> print cl set([<test.a instance at 0x00C866C0>, <test.a instance at 0x00C866E8>, <test.a instance at 0x00C86710>]) >>> cl["World"] <test.a instance at 0x00C866E8> Thanks!

• Unsure how to come up with a good design

  - by Mewzer

  Hello there, I am having trouble coming up with a good design for a group of classes and was hoping that someone could give me some guidance on best practices. I have kept the classes and member functions generic to make the problem simpler. Essentially, I have three classes (lets call them A, B, and C) as follows: class A { ... int GetX( void ) const { return x; }; int GetY( void ) const { return y; }; private: B b; // NOTE: A "has-a" B int x; int y; }; class B { ... void SetZ( int value ) { z = value }; private: int z; C c; // NOTE: B "has-a" C }; class C { private: ... void DoSomething(int x, int y){ ... }; void DoSomethingElse( int z ){ ... }; }; My problem is as follows: Class A uses its member variables "x" and "y" a lot internally. Class B uses its member variable "z" a lot internally. Class B needs to call C::DoSomething(), but C::DoSomething() needs the values of X and Y in class A passed in as arguments. C::DoSomethingElse() is called from say another class (e.g. D), but it needs to invoke SetZ() in class B!. As you can see, it is a bit of a mess as all the classes need information from one another!. Are there any design patterns I can use?. Any ideas would be much appreciated ....

• Trouble managing events in Flex/actionscript

  - by Zaka

  Hello all, I'm doing some newbie tests, so I decided to capture the keyboard events to move a rectangle. But I don't get the desired result. Unless I click on the TextArea box, I'm not able to capture the event key code. After that, all goes pretty well. I'm using Eclipse 3.3 + Flex 3.0 on Linux. Here's my code: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" enterFrame="enterFrame(event)" keyDown="onKeyDown(event)"> <mx:TextArea id="myText" x="200" y="200" width="100" height="100" /> <mx:Canvas id="myCanvas" x="0" y="0" width="100" height="100" /> <mx:Script> <![CDATA[ public var clearColor : uint = 0xFF456798; public var myPoint : Point = new Point(0,0); public function enterFrame(event:Event):void { myCanvas.graphics.clear(); myCanvas.graphics.beginFill(0xFF344ff0); myCanvas.graphics.drawRect(myPoint.x,myPoint.y,40,40); myCanvas.graphics.endFill(); } public function onKeyDown(event:KeyboardEvent):void { myText.text = "Keycode is: " + event.keyCode + "\n"; switch(event.keyCode) { case 37: //Left myPoint.x -= 1; break; case 38: //Up myPoint.y -= 1; break; case 39: //Right myPoint.x += 1; break; case 40: //Down myPoint.y += 1; break; } } ]]> </mx:Script> </mx:Application>

• How do I populate an NSMutableArray in one class with another object?

  - by AngeloS

  Hello, I know this is a simple answer, but I can't seem to find the solution. I created an object in its own class and I am trying to populate it with data from another class. For simple data types like NSString, I have no problem, but when trying make an NSMutableArray equal to another NSMutableArray or when I try to populate a NSMutableArray with another objects (like strings), I keep getting exception errors... Here is the object I am trying to populate: #import <Foundation/Foundation.h> @interface RSSFeedList : NSObject { NSString *subject; NSMutableArray *rssfeedDetail; } @property (nonatomic, retain) NSString *subject; @property (nonatomic, retain) NSMutableArray *rssfeedDetail; @end This is how I was able to populate the NSString 'subject' in another class: rssFeedList.subject = @"test"; However, if I follow similar convention within that same class with respect to an Array, it throws an exception: rssFeedList.rssfeedDetail = rssItemDetailArray; Where rssItemDetailArray is a NSMutableArray that I have built in the same class. I have also tried to add items (i tried strings for testing) to the NSMutableArray directly like so to no avail: [rssFeedList.rssfeedDetail addObject:@"test"]; Any ideas?? Thanks in advance!!

  Hello all, I have Windows 7 with the latest XAMPP installation. I configured BASE to work, for the most part. My problem is that in BASE, when I click on the graph alerts button, I get this error: Error loading the Graphing library: Check your Pear::Image_Graph installation! * Image_Graph can be found here:at http://pear.veggerby.dk/. Without this library no graphing operations can be performed. * Make sure PEAR libraries can be found by php at all: pear config-show | grep "PEAR directory" PEAR directory php_dir /usr/share/pear This path must be part of the include path of php (cf. /etc/php.ini): php -i | grep "include_path" include_path => .:/usr/share/pear:/usr/share/php => .:/usr/share/pear:/usr/share/php</code> I think it may have to do with the include path of the php.ini so here is what it currently says: ;;;;;;;;;;;;;;;;;;;;;;;;; ; Paths and Directories ; ;;;;;;;;;;;;;;;;;;;;;;;;; ; UNIX: "/path1:/path2" ;include_path = ".:/php/includes" ; ; Windows: "\path1;\path2" ;include_path = ".;c:\php\includes" ; ; PHP's default setting for include_path is ".;/path/to/php/pear" ; http://php.net/include-path include_path = ".;C:\xampp\php\PEAR" I am really at a loss as to how to resolve this. I searched for a while for some documentation but most referred to installing on ubuntu. I don't know any pear or php, so if you know how to fix this please explain thoroughly. I am willing to supply as much information as needed.
