How to build software that mimics topcoder, codingbat etc.?
|
<p>I want to build a downloadable desktop software which shows the user a GUI with a sample problem.</p>
<p><img src="http://i.stack.imgur.com/mxbww.png" alt="enter image description here"></p>
<p>The user then proceeds to code a solution and pastes it to a blank screen.</p>
<p>The program evaluates it and gives points to the user. The user progresses to the next level.</p>
<p>My question is, how do these sites evaluate a program for correctness? I don't mean to measure performance. </p>
<p>Do they write their own compiler or parse the text and feed it to javac and extract the output as well as search for some required keywords in the code.</p>

Android: how to draw TextView as focused?
|
<p>I have a series of Views in a tablelayout. Some are EditTexts, some are TextViews. I would like the TextViews to be focusable in the same way as the EditTexts; meaning, I would like them to be highlighted by the "up" and "down" arrows. <code>TextView.setFocusable(true)</code> allows them to gain focus from arrow keys, but they do not draw an orange border to indicate their focus like the EditTexts do. Is there an easy way to draw them as focused?</p>

Getting The ID Of URL
|
<p>Let say we have set of URLs like this</p>
<pre><code>yoursite.com/39827-key1-key2-key3
yoursite.com/132-key1-key2-key3
yoursite.com/9223455-key1-key2-key3
</code></pre>
<p>and so on
and let say with the help of .htaccess we can point all this urls to file say info.php
with the code </p>
<pre><code><?=id?>
</code></pre>
<p>it should gives the following ids (with respect to each url)</p>
<pre><code>39827-key1-key2-key3
132-key1-key2-key3
9223455-key1-key2-key3
</code></pre>
<p>My question now is there any way that we only get the number before first (-)
let say</p>
<pre><code>$id = 39827-key1-key2-key3
</code></pre>
<p>we need to make it</p>
<pre><code>$realid = 39827
</code></pre>
<p>so i wonder if there any preg_replace or any any idea that can remove first (-) and all after it. </p>
<p>example</p>
<pre><code>For $id = 39827-key1-key2-key3
$realid = (something),$id
Then finally $realid = 39827
</code></pre>
<p>it will helps me to create easy understandable url and retrieve its data from database.</p>
<p>Thanks you and sorry for poor english.</p>

Difference between SHA256CryptoServiceProvider and SHA256Managed
|
<p>The .Net SHA256Managed class is supported in all framework versions while the SHA256CryptoServiceProvider class is only supported from framework 3.5 and above.</p>
<p>Why is the SHA256CryptoServiceProvider introduced ? It seems to do the same as the SHA256Managed class, but the latter performs better. </p>
<p>What am I missing and why should I use the SHA256CryptoServiceProvider ?</p>

UIModalPresentationFullScreen gives error in UniversalApplication
|
<p>i am created Universal application, in that i used UIModalPresentationFull, for displaying MFMailComposerSheet in iPad, which helps me to show the full screen of a MailComposer view in landscape view of ipad. When i run the application in ipad simulator i works well. If i set it to iPhone simulator 3.0 or 3.1.3 it shows the error like "<strong>error: 'UIModalPresentationFullScreen' undeclared (first use in this function)</strong>" when i comment it and run in iPhone simulator it works what would be the solution for this error or, else is that any method replaces "UIModalPresentationFull" works in both ipad and iphone?</p>

implementing multiple string replace() using lambda function

<p>I've found tons of solutions doing exactly what I'm trying to do WITHOUT lambda...but I'm learning lambda today... </p>
<p>I have a string <code>stri</code> and I'm trying to replace some characters in <code>stri</code> that are all stored in a dictionary.</p>
<p><code>bad_chars={"\newline":" ","\n": " ", "\b":" ", "\f":" ", "\r":" ", "\t":" ", "\v":" ", "\0x00":" "}</code> and then I want to print <code>stri</code> out all pretty and empty of all of these ugly characters. My current code print's <code>stri</code> many many times. </p>
<p><code>format_ugly = lambda stri: [ stri.replace(i,j) for i,j in bad_chars.iteritems()]</code></p>
<p>Is there a way to make it print once, and with only 1 lambda function?</p>

List column logic
|
<p>I have a bunch of list items and I want to arrange them into 3 columns, alphabetically from top to bottom, left to right. This is easy enough to do by dividing the total amount of items by 3 and spitting them out. The other thing I need to do though is to keep the amount of items in each column even, starting at 4 per column.</p>
<p>Example:</p>
<pre><code>A E I
B F J
C G K
D H L
</code></pre>
<p>So if there were <= 4 items, it would just be 1 column</p>
<pre><code>A
B
C
D
</code></pre>
<p>The 5th item would start column 2 and the 9th would start column 3.</p>
<p>If there are > 12 items, it always adds it to the end of the rightmost column, starting a new row if the other columns have equal amounts of rows. Still maintaining alpha sort order.</p>
<p>So for 14:</p>
<pre><code>A F K
B G L
C H M
D I N
E J
</code></pre>
<p>And 16:</p>
<pre><code>A G L
B H M
C I N
D J O
E K P
F
</code></pre>
<p>I'm doing this on the server side and loading up 3 arrays (one for each column) so for 16 items it would be:</p>
<pre><code>$left_col = array('A', 'B', 'C', 'D', 'E', 'F');
$mid_col = array('G', 'H', 'I', 'J', 'K');
$right_col = array('L', 'M', 'N', 'O', 'P');
</code></pre>
<p>I want to keep this logic on the server side (PHP) rather than handle it with Javascript.</p>

Initialize a string variable in Python: "" or None?
|
<p>Suppose I have a class with a <strong>string</strong> instance attribute.
Should I initialize this attribute with <strong>""</strong> value or <strong>None</strong>? Is either okay?</p>
<pre><code>def __init__(self, mystr="")
self.mystr = mystr
</code></pre>
<p>or</p>
<pre><code>def __init__(self, mystr=None)
self.mystr = mystr
</code></pre>
<p><strong>Edit</strong>: What I thought is that if I use <strong>""</strong> as an initial value, I "<em>declare</em>" a variable to be of <strong>string</strong> type. And then I won't be able to assign any other type to it later. Am I right?</p>
<p><strong>Edit</strong>: I think it's important to note here, that my suggestion was WRONG. And there is no problem to assign another type to a variable. I liked a comment of <strong>S.Lott</strong>: "<em>Since nothing in Python is "declared", you're not thinking about this the right way.</em>"</p>

Accessing internal expando id for an element
|
<p>I've been having issues with on/off removing event handlers that I don't want to, and would like to namespace the event binding with the html element's expando id. </p>
<pre><code>function SomeWidget(el) {
$(document).on('handler.MY_EXPANDO_ID', this.handler.bind(this));
};
var widget = new SomeWidget($(sometargetelement));
</code></pre>
<p>The problem with not having a unique identifier, is that currently I have namespaces the same, which screws up when I have two widgets of the same time, and one removed, it removed the handler for both objects.</p>
<p>Question 1) How do I access an elements' internal expando id?
Question 2) Is there a better way to do this? Function.bind !== Function, which makes removing based on the actual method pointer not possible</p>

find current directory level with PHP
|
<p>I need to require_once a file that is located in my sites root directory. The problem I have is that I won't always know how many levels up the root directory is from where my current script is running. So I need to figure out how many directory levels I need to go up to require_once my file.</p>
<p>Some times it could be:</p>
<pre><code>require_once '../../file.php';
</code></pre>
<p>And some times it could be:</p>
<pre><code>require_once '../file.php';
</code></pre>
<p>Or any other number of directory levels up.</p>
<p>How can I calculate how many "../" I need to get to the root directory from any location in a sub directory?</p>

How to protect the .php file with JSON object when accessed through url in the browser
|
<p>I hope that this is not too difficult, so here is a story, I have created a simple process which is being sent as JSON object when requested, but for security reasons, would really like to protect (403) the content of the file if it is accessed by placing a full URL to it in the browser. </p>
<p>Here is a script inside my ajax.php</p>
<pre><code><?php
$image = array(
"/trial/images/1.png",
"/trial/images/2.png",
"/trial/images/3.png",
"/trial/images/4.png"
);
$msg = array(
'status' => 1,
'message' => 'Remember to +1',
'html' => '<p>Thank you for downloading our software <img src="'. $image[array_rand($image)] .'" width="80" height="80" alt="Thank You"></p>'
);
echo json_encode($msg);
?>
</code></pre>
<p>and here is a script of the function that I am using to POST with ajax into that file to obtain JSON object out.</p>
<pre><code>function custom_reminder(aElem){
theLink=$(aElem).attr("href");
$.ajax({
type:"POST",
url:"/includes/ajax.php",
data:"action=reminder&thepath="+theLink,
dataType:"json",
error:function(){window.location=theLink;},
success:function(msg){
if(msg.status == 1) {
display_reminder(msg.html,theLink);
}else{
custom_message(msg.message,"error");
}
}
});
}

getting incorrect fileextension and content type
|
<p>I have an asp.net application where the users can upload files to our database. sometimes when they upload the files, the content-type is set as "application/octet-stream" which is a binary file. When I ask the user, they say that they uploaded the "tif" file but somehow the upload control sets it as "application/octet-stream". when I upload the same tif file from my computer it uploads with the correct content type (application/octet-stream). </p>
<p>Also, I am using the following code to get the fileextension</p>
<pre><code>fileExtension = filUpload.PostedFile.FileName.Substring(filUpload.PostedFile.FileName.LastIndexOf(".") + 1)
</code></pre>
<p>sometimes it returns the file extension as "c:\documen" or "j:\testing" etc. I know that windows doesn't allow special characters in the filename.</p>

<p>When I clicked checkbox into first div (class avalible) then function has been successfull executed - this chekbox is child of main div (#banner-menu-holder).</p>
<p>When I clicked second div's checkboxes and the function had not worked. jQuery didn't detected that these checkboxes are children of main div.</p>

jQuery addClass to element based on attribute value
|
<p>I am stuck with this and need some help. I know the logical solution for this, but not sure how to translate it to jQuery code (newbie here :)). Any suggestions or help greatly appreciated!</p>
<p>I need to add a css class (active class), to an element that has a title attribute equal to the value of a variable. So, let's say my variable currentElement = 'great day'. There is also an a tag element on the page that has the title attribute of 'great day', such as <code><a title='great day' href='#'></code>.</p>
<p>With jQuery I want to: Find a tag in the DOM where currentElement == a tag title and add css class. So, ideally it should find that a tag and add the css class to it.</p>
<p>I came up with something like this but not working:</p>
<pre><code>/* set currentElement var to the src attribute
value of an a tag on the page
this works */
var currentElement = $('#greatLink'] img[src*=' + test + ']').attr('src');
/* now find an a tag on the page that has
the same title attribute as var currentElement
this does not work */
$("a[title ='+currentElement+']").addClass('selectedThumb');

Is it safe to downgrade an iphone app to a previous SDK?

<p>I have released an app with the 2.2.1 SDK, to realize that I'm pointlessly losing a big percentage of customers still on firmware 2.2 (See this article: <a href="http://arstechnica.com/apple/news/2009/03/app-store-lessons-firmware-followup.ars" rel="nofollow">http://arstechnica.com/apple/news/2009/03/app-store-lessons-firmware-followup.ars</a>) So I'm thinking of updating the app to the previous SDK, 2.2.</p>
<p>I was wondering if anyone has run into any problem doing this? Is this safe for customers who have already installed the previous version, to install my "downgrading" update?</p>

Expand only one row in javascript code
|
<p>hey guys having trouble figuring out how to make it so that i can make it only open one table at once, once you open another the other should close any help here? </p>
<pre><code>function showRow(cctab){
if (document.getElementById(cctab)) {
document.getElementById(cctab).style.display = '';

<p>Is there a way to refresh a UIView which will subsequently call drawRect?</p>

In JS, which is faster: Object's "in" operator or Array's indexof?
|
<p>I want to keep a list of strings that I will only ever check for the presence of, eg:</p>
<pre><code>corporatePlan = [
'canDeAuthorize',
'hasGmailSupport',
'canShareReports',
'canSummonKraken',
'etc'
]
</code></pre>
<p>So, when the user tries to summon the kraken, I'll do <code>corporatePlan.indexof('canSummonKraken') != -1</code> to see if he can.</p>
<p>A coworker suggests that it would be faster to store it as an object:</p>
<pre><code>"Corporate Plan" = {
'canDeAuthorize' : null,
'hasGmailSupport' : null,
'canShareReports' : null,
'canSummonKraken' : null,
'etc' : null
}
</code></pre>
<p>And just do something like <code>'canSummonKraken' in corporatePlan</code> to check if the plan contains that key. This makes sense in a classic CS sense, since of course 'contains' is constant time on a map and linear on an array. Does this check out against how arrays and objects are implemented under the hood in JS, though?</p>
<p>In our particular case, with less than 100 elements, the speed doesn't matter much. But for a larger array, which way would be faster on access?</p>

Conflict with jscrollPane and animate
|
<p>I am using jscollPane on a div that is displayed via the jquery animate function.</p>
<p>The animate function seems to be causing a conflict with the jscrollpane script and thus the scrollbars do not show. </p>
<p>Here is an example page to demonstrate: <a href="http://mikesewell.net/dev/scrollpane/" rel="nofollow">http://mikesewell.net/dev/scrollpane/</a></p>
<p>The div #text is hidden using display: none; it is shown using this function:</p>
<pre><code>$(".bio-button").hover(function() {
$(this).next("#text").animate({opacity: "show"}, "slow");
}
</code></pre>
<p>If I dont' hide #text jscrollPane works fine, but if using this function to animate stops the scrollbars from showing.</p>
<p>Any suggestions would be greatly, greatly appreciated. Thanks!!</p>

java - how to open a program and detect when the program is closed
|
<p>My main method opens an app and sets <code>running</code> to false after it has finished executing, the only problem is that I want to to set <code>running</code> to false only once the opened app has been closed. Is there any easy way to do this?</p>
<p>This is my code:</p>
<pre><code>Runtime runtime = Runtime.getRuntime();
boolean running = true;
try {
Process p = runtime.exec("open test.app");
p.waitFor();
} catch (InterruptedException e) {}
running = false;
</code></pre>
<p>EDIT: What happens at the moment is it opens <code>test.app</code>, then it sets <code>running</code> to false even though the app is still running.</p>

Access modifier for php class properties
|
<p>Why doesn't php have default access modifier for Class properties (like functions - functions do have a default : <a href="http://stackoverflow.com/questions/2224380/default-visibility-of-class-methods-in-php">Default visibility of class methods in PHP</a>) ? It always forces you to use one of the access modifiers(private,public or protected) or var. Would it make more sense to have a default access modifier like 'public' if none is specified ? What was the logic of not providing one ?
Am no php expert so please excuse if i am missing anything obvious.</p>

newbie questions about overloading contructors
|
<p>While I have done OOP before, I am just learning Java.</p>
<p>I have a 3 questions on overloaded constructors:</p>
<p>1.On the line marked line 1,
I am calling an overloaded constructor but the compiler doesn't resolve the call,<br>
is there something else I need to do?</p>
<ol>
<li><p>On the line marked with a 2,
The compiler complains that the "this()" needs to be the first statement in the
method, when it is. What's with that?</p></li>
<li><p>If I am writing an overloaded constructor, and I haven't overridden the default constructor do I need an explicit "this();" in the overloaded constructor, if i want to execute the behavior of the default constructor, or is it included in all constructors for "free"?</p></li>
</ol>
<p>.</p>
<pre><code>class JavaSnippet {
public static void main(String[] args) {
String MenuItemName="Coffee";
double MenuItemPrice=1.0;
Item MenuItem;
//1-> MenuItem=new Item(MenuItemName,MenuItemPrice);// Get "cannot find symbol"
}
}
class Item {
String name;
double price;
public void Item(String InName, double InPrice) {
// 2-> this();// get "call to this must be first statement in constructor"

difficulty referencing functions, using prototype

<p>I am working on HTML 5 Canvas game, with a gameloop. </p>
<p>Here is my code so far. It doesn't do anything and that is fine, but I am getting an error</p>
<p>TypeError: Object [object DOMWindow] has no method 'Update' [http://localhost:2516/scripts/lib/Game.js:47] </p>
<p>Edit: This code works, it no longer reflects the problem, it reflects the solution</p>
<pre><code> var game;
var Game = function () {
}
Game.prototype.Update = function () {
}
Game.prototype.Draw = function () {
}
function GameLoop () {
game.Update(); //this is line 47
//context.save();
game.Draw();
// context.restore();
setTimeout(GameLoop, 10);
}
function Start() {
game = new Game();
GameLoop();
}
</code></pre>

Error with a href click
|
<p>I have a problem to share with you guys..In my page I have different tabs that was created by some method, before moving onto another tab i need to do some validations, but the problem is when i click next tab the page is submitted before going to my validation check even though they check the validation script is executed but because of the page is submitted first it's moving to the next tab.How can i prevent moving to next tab if validation is false.</p>
<p>Code for a href click: </p>
<pre><code><a onclick="adc.FormHandler.goto('user_edit', 0); return false;"
href="#">
<i data="1" class="icon-tab-num"></i>
General Info
</a>
</code></pre>
<p>code for actual click function</p>
<pre><code>if (null !== document.forms[formName]) {
document.forms[formName].elements['__goto'].value = gotoIndex;
document.forms[formName].submit();
return false;
}
</code></pre>
<p>I can't modify these scripts because this is a general script and created by some other team memeber.I am using jquery for validation.</p>

Context Menu for ListView
|
<p>I have a <code>ListView</code> with a customized adapter in my application. I want to add a <code>ContextMenu</code> for deleting items in this <code>ListView</code> </p>
<p>in my <code>onCreate</code> method I register the <code>Context Menu</code>:</p>
<pre><code>registerForContextMenu(lastCases);
</code></pre>
<p>where the parameter is my ListView</p>
<p>This should call this method: </p>
<pre><code>@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
Log.i("onCreateContextMenu: ", "Inside");
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.stock_file_menu, menu);
}
</code></pre>
<p>As you can see I use the Logger to log info whenever this method is called. But it doesn't outputs anything to <code>LogCat</code>, which indicates that this method is never fired off.</p>
<p>Also I should mention that my <code>ListView</code> is filled with information from this method: </p>
<pre><code>private void RefreshCaseList() {
lastTenCases = db.getAllCases(10);
if (lastTenCases.size() > 0)
error.setText("");
lastCases.setAdapter(new CustomAdapter(myClass.this, lastTenCases));
}
</code></pre>
<p>This method grabs some objects from a database, and fills the <code>ListView</code> with these objects, but this method is called before I register the <code>context menu</code> in <code>OnCreate</code>. </p>
<p>No errors does occure so I doesn't have any more information that can help me. Anybody how knows how to make a <code>Context Menu</code> for a <code>ListView</code> with a customized adapter? </p>
<p>Thanks in advance!</p>

}
@Override

<ul>
<li>While on main screen, I click preferences icon in action bar, PrefsFragment starts.</li>
<li>While on PrefsFragment, I click preferences icon in action bar PrefsFragment starts <strong>again</strong> (this is where problem arise).</li>
<li>I hit the back button and it reverts fragment transaction and goes back to <strong>PrefsFragment</strong>. (it should go back to main screen).</li>
</ul>
<p><strong>Question:</strong>
Is there any smart way to disable double showing PrefsFragment?</p>
<p><strong>Desired outcome:</strong>
Clicking prefs icon in action bar if on main screen shows PrefsFragement, clicking prefs icon in action bar while PrefsFragemnt is visible does nothing, clicking back button while on PrefsFragment always goes back to main screen.</p>

How can I make text into links using jQuery?
|
<p>I'm trying to make a reply system for the comments on my blog. When someone clicks on "Reply" it will take the comment id and put two brackets infront of it in comment textbox.</p>
<p>Basically it will look like this <strong>>>123456789</strong>, it's not a link or anything it's just plain text. Once it's been posted the brackets are converted to <code>&gt;</code> so it'll look like this in the final source code: <strong><code>&gt;&gt;123456789</code></strong> (every id has 9 numbers)</p>
<p>I need to make that text into a link.</p>
<p>Here's what's supposed to happen:
<a href="http://jsfiddle.net/KFXFd/" rel="nofollow">http://jsfiddle.net/KFXFd/</a><br>
Here's what happens when I try to change the class:
<a href="http://jsfiddle.net/qWYCQ/" rel="nofollow">http://jsfiddle.net/qWYCQ/</a></p>
<p>Note that the class has to be <strong>.commenttext</strong> instead of <strong>body</strong>, but for some reason I can't get it working (I'm terrible at js).</p>

C++: String and unions
|
<p>I'm having a (design) problem:
I'm building an interpreter and I need some storage for variables. There are basically two types of content a variable here can have: <code>string</code> or <code>int</code>.</p>
<p>I'm using a simple class for the variables, all variables are then stored in a vector.</p>
<p>However, as a variable can hold a number or a string, I don't want C++ to allocate both and consume memory for no reason.</p>
<p>That's why I wanted to use unions:</p>
<pre><code>union
{
string StringValue;
int IntValue;
}
</code></pre>
<p>However, strings don't work with unions.</p>

<li>Is there any workaround so no memory gets eaten for no reason?</li>

Making my own data type
|
<p>I'm new to programming and Java. I'm trying to write my own data type/collection class but I'm not quite sure how to go about it. </p>
<p>I want a class that contains a string, and an array-list of strings.</p>
<p>Usually I would go about making a data type like this:</p>
<pre><code>public class Collection {
private int id;
private String word;
private int howMany;
private char firstChar;
public Collection (int i, String w, int h, char f){
id = i;
word = w;
howMany = h;
firstChar = f;
}
//Getters and Setters
}
</code></pre>
<p>Not sure how I can do this with an ArrayList field. </p>
<p>My goal behind this is to have a class of unique words in the string field read in from .txt files and in the arraylist field have all the .txt file names that contain that word. </p>
<p>Edit: Building on Tom Anderson's Response and what I initially thought to do:</p>
<pre><code>public class Collection {
private int id;
private String word;
private int howMany;
private char firstChar;
private List<String> filenames;
public Collection (int i, String w, int h, char f, List<String> filenames){
id = i;
word = w;
howMany = h;
firstChar = f;
this.filenames = filenames;
}
}
</code></pre>
<p>I'm still not sure how to use this since I can not simply add a string to the ArrayList parameter when creating a new instance of the my Collection Class. Such as this:</p>
<pre><code>ArrayList<Collection> collection = new ArrayList<Collection>();
Collection newTest= new Collection("test","test");
collection.add(newTest);
</code></pre>

<p>When I run my application on a physical phone from within Eclipse, my Google MapView works perfectly. If export the app to an apk file and install it to the same phone from the command line with adb then the MapView comes up but shows only the Google logo and grid - no map tiles appear. I'm using a debug application key and a GMaps API key generated with that debug key. I've verified that this happens on both the Droid and N1 phones. The logcat looks identical in both the working and non-working cases - no obvious error messages.</p>
<p>Any ideas what might be wrong?</p>

Honeycomb is not passing the app_data bundle to my search results activity
|
<p>This code which works fine in previous versions of Android is not working on 3.0:</p>
<pre>
public boolean onSearchRequested()
{
Bundle currentData = new Bundle();
currentData.putLong(Folder.FOLDER_LUID, folderId);
startSearch (lastSearchText, false, currentData, false);
return true;
}
</pre>
<p>The app_data bundle is NOT in the intent passed to my search results activity.
Is there perhaps some new configuration that must be done to get this data passed in the intent?</p>

Another typedef error with C++
|
<pre><code>#ifndef C_H
#define C_H
#include <memory>
class C
{
public:
C(){};
~C() {};
};
typedef auto_ptr<C> CPtr;
#endif
</code></pre>
<p>The above codes seem fine for me, but when I compile them with VC10, I got the following errors:
"error C2143: syntax error : missing ';' before '<'". Any ideas about it will be appreciated. </p>
