very basic java method
|
<p>I am a beginner in java and am writing a stack class using array.</p>
<p>So I have a method in this class called pop</p>
<pre><code> public int Pop(){
if (current_size >0)
{ // do something
return ele;
}
// return nothing <-- ths is where error is
}
</code></pre>
<p>Since i have the return type int.. the class is always expecting to return something.
How should I tackle such cases where the method wil return something if the condition is true else it wont shouldnt return anything?
Thanks</p>

javascript: this keyword
|
<p>I know <code>this</code> points to current object on which function operates. So here is the code as per the definition</p>
<pre><code>function foo(){
alert(this); //output==window
}
</code></pre>
<p>So, now function foo is equal to window.foo()
but now here</p>
<pre><code>function foo(){
function fo(){
alert(this);
}
fo();
}
</code></pre>
<p>so,now when <code>foo</code> gets executed output is again window object why? since the nested <code>this</code> should refer to different object.since fo() is now not operating on window object as foo()==window.foo() .so nested function should now point to different object</p>
<p>see here for detail:</p>
<pre><code> function foo()
{
alert(this);
function fo(){alert(this);}
as();
}
</code></pre>
<p>if now,var x=new foo();than "this" within the foo() method points to object object but the nested this points to global object right?now u should be clear what i meant to say</p>

Permissions with PendingIntent.getBroadcast() and AlarmManager
|
<p>Is there a way to enforce receiver permissions for intents broadcast by the AlarmManager? For example, I want to do this:</p>
<pre><code>AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent("myapp.MY_ACTION");
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, intent, 0);
am.setRepeating(AlarmManager.RTC_WAKEUP, now, MY_INTERVAL, pendingIntent);
</code></pre>
<p>But make the broadcasts sent by the AlarmManager act like this:</p>
<pre><code>sendBroadcast(intent, "myapp.permission.RECEIVE_BROADCASTS");
</code></pre>

Assign a value to a struct value-type
|
<p>I want to be able to create a struct, and use it like a normal built-in.
For example, say I decide that the Bool should also have a FileNotFound value (as a silly example!), so I create a struct to include that - what would it take to be able to use it as a normal struct in code (ie. assign to it), as in
bool b = true; or
b = FileNotFound;</p>
<p>The Bool is a struct, right? And you can do it with the other built-ins:
int i = 32; or
byte b = 123;</p>
<p>I want to do my own!
Anyone got any ideas...?</p>

C++: Outputing Multidimensional Arrays on loop?
|
<p>Hi everybody I have being trying to do this the whole morning but I can't seem to make it work and is to output a multidimensional array on a loop, let me explain better with a non multidimensional one:</p>
<pre><code>int j;
int line[4] = {1, 2, 3, 4,};
for(j = 0; j < 4; j ++)
{
cout << line[j] << endl;
}
</code></pre>
<p>This works but when for multidimensional arrays comes its headache:</p>
<pre><code>int i, j;
int line[2][2];
line[0][0] = 99;
line[0][1] = 98;
line[1][0] = 97;
line[1][1] = 96;
i = 0;
j = 0;
for(j; j <= 1; j ++)
{
for(i; i <= j; i ++)
{
cout << line[i][j] << endl;

normal way of using variables throughout python
|
<p>What is the standard way of declaring configuration variables for your program at the top of a python script? These are used throughout the program in multiple classes and functions. Is the best way:</p>
<ol>
<li><p>To create a mixed dictionary with the configuration options, and pass these to any classes that need them. Downside: this requires passing extra attributes. For example:</p>
<pre><code>config = {'parseTags': {'title','font','p'},
'name': 'steve',
'logFrequencies': 10,
'print_rate': False
}
</code></pre>
<p> </p>
<pre><code>newCustomObject = CustomClass(config)
customfunction(config)
print 'hi',config['name']
</code></pre></li>
<li><p>Create global variables at the beginning of the file and call those throughout the program. Downside: ruins the encapsulation of the classes.</p></li>
<li><p>Something else.</p></li>
</ol>
<p>What is the most pythonic way of doing this?</p>

Display image using a RSS feed
|
<p>I have an application in which use a RSS feed reader. My problem is that I don't know what is the best way to display an image. The closer I could get was to pull the image description (). I know I could parse this String by myself and get the image url, but I was wondering if there is a more elegant way to solve this issue. I tried using the SAX and the DOM classes, but I couldn't figure it out. </p>
<p>Thanks a lot,

php code md5 hashing explanation
|
<p>I am working with the moodle system, but it turns out that it uses md5 salt hashing. I found some come, so maybe you could explaint it to me because I am have only basic knowledge of php.</p>
<pre><code>function validate_internal_user_password($user, $password) {
global $CFG;
if (!isset($CFG->passwordsaltmain)) {
$CFG->passwordsaltmain = '';
}
$validated = false;
if ($user->password === 'not cached') {
// internal password is not used at all, it can not validate
} else if ($user->password === md5($password.$CFG->passwordsaltmain)
or $user->password === md5($password)
or $user->password === md5(addslashes($password).$CFG->passwordsaltmain)
or $user->password === md5(addslashes($password))) {
// note: we are intentionally using the addslashes() here because we
// need to accept old password hashes of passwords with magic quotes
$validated = true;
} else {
for ($i=1; $i<=20; $i++) { //20 alternative salts should be enough, right?
$alt = 'passwordsaltalt'.$i;
if (!empty($CFG->$alt)) {
if ($user->password === md5($password.$CFG->$alt) or $user->password === md5(addslashes($password).$CFG->$alt)) {
$validated = true;
break;
}
}
}
}
if ($validated) {
// force update of password hash using latest main password salt and encoding if needed
update_internal_user_password($user, $password);
}
return $validated;
</code></pre>
<p>}</p>
<p>Would it be hard to change it that after entering simple text it would became hashed?</p>

document.location / parent.location - Can they be blocked?

<p>I am using the above 2 commands on my website. It seems they work for 95% of people visiting the page it should trigger but for others it doesn't.</p>
<p>Does anyone know if these javascript commands can be blocked at all? I am having a real headache finding out why they don't work sometimes.</p>
<p>p.s I am not using these for spam or anything, just for processing payments.</p>

The char* constant value ERROR with GNU G++ compiler
|
<p>I write sevaral files with the relationship like:</p>
<p>file A.h:</p>
<pre><code>#ifndef MACRO_HEADER
#define MACRO_HEADER
const char* CONST_CHAR_NAME = "name";
#endif
</code></pre>
<p>file B.h(B.cpp) and file C.h(C.cpp) also include this common type definition header A.h.
When the g++ finally combines the obj files to lib, it gives out he redefinition error.I confess that I make a mistake and I should define the constant as:</p>
<pre><code>const char* const CONST_CHAR_NAME = "name"; //This is OK
</code></pre>
<p>But why compiler gives me a redefinition ERROR? Is const char* not a constant value?But I use typeid.name to check the types of <code>const char *</code> and <code>cosnt char* const</code>. They are the same:<strong>char const *</strong> . I am confused with the ERROR.</p>

open two different socket input stream

If server receives <code>add</code>, it adds the object it receives from the socket to a local list. Is it acceptable to open two different streams consecutively to receive two different objects?</p>

Do template parameters need to be forward declared or does the type definition to be known
|
<p>Basically I have this code, but GCC complains that the vector cannot
be constructed with an empty type. Has anybody encountered this problem
before? I should mention that Vertex3D is only used through pointers in
the file and so there should be no reason for the whole type to be
known by the compiler. I dont know how templates behave in this
respect..</p>
<pre><code>//#include "cgVertex3D.hpp"
#include "cgDirection3D.hpp"
#include "cgHandedness.hpp"
class Vertex3D; // Forward declaration to avoid mutual header include
class Polygon3D {
// Vertices constituting this polygon

That is, for example, the code can print "Haha, you are in debug" when "Debug As Java Application" but print nothing when "Run As Java Application" (I don't want to append any args when invoking main method). Is there any general method to implement this which can work under any IDEs, like eclipse, IntelliJ etc?</p>

Working with JavaScript prototypes and accessing base class fields.
|
<p>I am new to pseudo classes and prototypes in JavaScript and I am having a bit of difficulty implementing it properly. What I am trying to do is have a base 'class' with some fields then create a prototype of that base class with my methods defined as object literals. I am torn between doing it this way and just using singletons inside my base class for my methods. I think though that doing it this way is a little more elegant and I think I am actually not creating every method every time I create a new object. </p>
<p>Anyways, the small issue I am having is referencing the fields of my base class in my methods. Because when I try to reference them as this.field this is referring to the current function/ scope but I want it to reference the newly create object. Is there a work around for this or should I change the way I am creating my methods. </p>
<p>Below is some code that I think will make it more clear what I am doing and the problem I am having.</p>
<pre><code>function BaseClass() {
this.items[];
this.fieldOne = "asdasd";
}
BaseClass.prototype = {
methodOne: function (input) {
function addElement(a. b) {
var element = {};
element.prop1 = a;
element.prop2 = b;
//The issue I am having is that items is undefined, how can I refernce the parent class object.
this.items.push(element);
}
function traverse() {
//go through a list and add a bunch of elements
addElement("ASdasd", 324);
}
},
methodTwo: function () {
//see now fieldOne is asdasd
console.log("fieldOne" + fieldOne);
}
}
var forTest = new BaseClass();
forTest.methodTwo();
</code></pre>
<p>So yeah I want to have some fields in the parent class that I can access from any method, but I would rather not just put the functions in my base class so that I do not create every method everytime I create a new object from BaseClass. Is there a work around or a better way to implement this? </p>
<p>Thanks in advance for the help. </p>

Is it possible to prevent launching other applications?
|
<p>I am doing building an application for an app-store market. They gave me following scenario. but I'm not sure it is possible. please give me your advice and suggestions. </p>
<p>This is the scenario:
-User upload his application into this market.
-We wrap that application with our application (I'll explain later).
-Then we will put it in store</p>
<p>More explanation:
This wrapper should bring the ability of buying (daily, monthly and etc.) to the user. If the user had some amount of money in his account then our application should let the user download and launch the game (for example). If user download a game from market and installed it in his device, each time this game is launched we should check his account to see if it has sufficient money. if he didn't have we should prevent launching the application.</p>
<p>I think it is not possible. If a game is installed in a device therefore it is installed. we can't lunch our application when user lunch other games. Am I right? Is there any way to lunch our application any time user clicks other games or applications? </p>

Disable activity from another activity?
|
<p>I am using the following code to remove my app from the launcher:</p>
<pre><code>if (!dialercode.getText().toString().equals("")) {
getPackageManager().setComponentEnabledSetting(
getComponentName(),
PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
PackageManager.DONT_KILL_APP);
}
</code></pre>
<p>However, that also stops that activity being launched through other means (secret code).</p>
<p>So, I have setup a separate Launcher activity that will be disabled instead (all the Launcher activity does is launch the main activity).</p>
<p>However, I don't know how to go about disabling the Launcher.java activity via the main activity - IE how do I get the component name for the Launcher activity when I'm in a different activity?</p>

CSV find max in column and append new data
|
<p>I asked a question about two hours ago regarding the reading and writing of data from a website. I've spent the last two hours since then trying to find a way to read the maximum date value from column 'A' of the output, comparing that value to the refreshed website data, and appending any new data to the csv file without overriding the old ones or creating duplicates.</p>
<p>The code that is currently 100% working is this:</p>
<pre><code>import requests
symbol = "mtgoxUSD"
url = 'http://api.bitcoincharts.com/v1/trades.csv?symbol={}'.format(symbol)
data = requests.get(url)
with open("trades_{}.csv".format(symbol), "r+") as f:
f.write(data.text)
</code></pre>
<p>I've tried various ways of finding the maximum value of column 'A'. I've tried a bunch of different ways of using "Dict" and other methods of sorting/finding max, and even using pandas and numpy libs. None of which seem to work. Could someone point me in the direction of a decent way to find the maximum of a column from the .csv file? Thanks!</p>

jQuery - Pausing and resuming a looping animation too quickly causes the queue to go haywire
|
<p>I have the following code that animates forever, pauses at the end of the current animation on mouse enter, and resumes on mouse leave. It works how I want it to except for one issue.</p>
<p>If I hover in and out of the element too quickly (e.g. by cutting across the corner) it causes some kind of queue build up and everything goes haywire. However when I actually check the queue there's nothing strange in it and the animations are obviously not even running in the queued order.</p>
<p>Using the following code waggle your mouse in and out of the grey area. When you eventually allow the animations to resume they will go haywire (also available at <a href="http://jsfiddle.net/54YTx/" rel="nofollow">http://jsfiddle.net/54YTx/</a>).</p>
<pre><code>$('body').html('<div style="background: lightgrey;">Testing</div>');
function do_animations() {
// Always 0 or 1
console.log($('div').queue('fx').length);
$('div')
.delay(1000)
// Hardcoded numbers mean that resuming from the bottom position takes longer but it doesn't matter in this simple example
.animate({'padding-top': '100px'}, 1000)
.animate({'padding-top': '0px'}, 1000)
// Queue instead of callback so that clearQueue() can stop the loop reliably
.queue(function() {
do_animations();
$('div').dequeue();
});
};
do_animations();
$('div').hover(function() {
// Don't use stop(). We want the current animation to finish
$('div').clearQueue();
}, function() {
do_animations();
});

Can I use jQuery to show when my Ajax query is in progress?
|
<p>I am using the following javascript to detect when a field is changed:</p>
<pre><code><script type="text/javascript">
$(document).ready(function () {
$("select[id^='Status_'], input[id^='Position_']").change(function (e) {
var type = $(this).attr('id').split('_')[0];
updateField('Account', $(this), type);
});
});
</script>
</code></pre>
<p>This then calls the following to updata data in the database:</p>
<pre><code>function updateField(entity, obj, type) {
var val = obj.val();
var idArr = obj.attr("id");
var idTmp = idArr.split("_");
var id = idTmp[1];
var pk = $('#Meta_PartitionKey').val();
var rk = $("div[id='rk_" + id + "']").html();
$.ajax({
cache: false,
url: "/Administration/" + entity + "s/Update",
data: {
pk: pk,
rk: rk,
fld: type,
val: val
}
});
};
</code></pre>
<p>Is there some way that I could provide a visual clue to the user that the update is taking place. Something like changing the cursor and then changing it back.</p>
<p>Also how can I give a message to show if the update failed to my users?</p>

$("form").each(function(){
if("this element supports disabled"){
$(this).attr("disabled", "disabled");
}
});
});
</code></pre>
<p>I was thinking that if the element does not support this property then it should be skipped.</p>
<p>In my example above, I was checking if the element supports the disabled attribute.</p>
<p>Thanks</p>

Allowing connections given the number of threads in server
|
<p>Every connection requires one thread for each, and for now, we're allowing only certain number of connections per period. So every time a user connects, we increment the counter if we're within certain period from the last time we set the check time. </p>
<pre><code>1.get current_time = time(0)
2.if current_time is OUTSIDE certain period from check_time,
set counter = 0, and check_time = current_time.
3.(otherwise, just leave it the way it is)
4.if counter < LIMIT, counter++ and return TRUE
5.Otherwise return FALSE
</code></pre>
<p>But this is independent of actually how many threads we have running in the server, so I'm thinking of a way to allow connections depending on this number.</p>
<p>The problem is that we're actually using a third-party api for this, and we don't know exactly how long the connection will last. First I thought of creating a child thread and run ps on it to pass the result to the parent thread, but it seems like it's going to take more time since I'll have to parse the output result to get the total number of threads, etc. I'm actually not sure if I'm making any sense.. I'm using c++ by the way. Do you guys have any suggestions as to how I could implement the new checking method? It'll be very much appreciated. </p>

c# backspace simulator - deletes entire word instead of just a letter?
|
<p>I am writing a simple C# program in which when I press "ctrl+g" I want my program to automatically delete the character directly left of the cursor in any program (ex: chrome browser, word document, powerpoint document, etc...).
I have installed a global hook for "ctrl+g" and it works fine. I am using a keyboard simulator that I found from codeproject: <a href="http://www.codeproject.com/Articles/28064/Global-Mouse-and-Keyboard-Library" rel="nofollow">http://www.codeproject.com/Articles/28064/Global-Mouse-and-Keyboard-Library</a>
My issue is that when I simulate a backspace like so:</p>
<pre><code>KeyboardSimulator.KeyPress(Keys.Back);
</code></pre>
<p>the entire word is deleted instead of just the character to the left of the cursor. For example, if I am in a Microsoft Word document with the following line of text:
"Happy new year"
if my cursor is at the end of "year" and I press ctrl+g, my program deletes "year" and puts the cursor just to the right of "new" instead of just deleting the letter "r" of "year".
I have tried other simulators as well with the same result. Does anyone have a solution or know what I am doing incorrectly?
Thanks.</p>

static local variable and static local object initialization
|
<p>In VC++2008 there is a serious difference in initialization of static local variable and static local object. Static local variable is initialized before main() and its definition statement within the function is skipped. Static local object is initialized by 0 value before main() and its definition statement within the function is executed only once . Constructor is started and object is initialized by appropiate value. All that can be seen in Debug mode. Does this solution correspond to the existing C++ Standard?</p>

Sending notification to Android Application using PHP
|
<p>I am making an android application that can be remotely managed by PHP.</p>
<p>I mean like, for example, I want to send a notification to the android app.
My android app will then fetch it and process it.</p>
<p>I have an idea, my PHP program will just save this notification to "pending notifications table" then my android app will fetch it. But my android app will always fetch like for example every 5 seconds, get pending notifications, and even if no pending notifications, it will just fetch and fetch every 5 seconds which I think not a better solution for this.</p>
<p>What I want to do is, when I send a notification to the android app using PHP, it will automatically be processed.</p>
<p>Any better solution to this?</p>
<p>Thank you. </p>
<p>PS.
What I mean with notifications are not push notifications. It's like a command that I will send to the android app.</p>

Capitalizing the first character of a string - Java
|
<p>I've looked all over for how to capitalize the first character of a string, but nothing I've found has helped. For my method to work, I need to set a user entered string to lower case.</p>
<pre><code>sourceText = enterText.getText();
char chr = sourceText.charAt(0);
</code></pre>
<p>so I have a boolean that's true if the first character is uppercase.</p>
<pre><code>boolean upperCase = Character.isUpperCase(chr);
sourceTextLower = sourceText.toLowerCase();
</code></pre>
<p>Cool stuff happens here, and the final product is another string called translatedTextString and an if statement</p>
<pre><code>String s2 = "";
if(upperCase == true)
{
int x = translatedTextString.length();
s2 = translatedTextString.substring(0,1).toUpperCase().concat(translatedTextString.substring(1, x));
}
//translatedText is a label
translatedText.setText(s2);
</code></pre>
<p>However, when I run the program, the first character of my result is still lower case. So my questions is: is this even the right way to go about doing this? If so, what am I doing wrong, and if not, how can I do it correctly?</p>

BaseType of a Basetype
|
<p>this is my first question here so I hope I can articulate it well and hopefully it won't be too mind-numbingly easy.</p>
<p>I have the following class <em>SubSim</em> which extends <em>Sim</em>, which is extending <em>MainSim</em>. In a completely separate class (and library as well) I need to check if an object being passed through is a type of <em>MainSim</em>. So the following is done to check;</p>
<pre>
Type t = GetType(sim);
//in this case, sim = SubSim
if (t != null)
{
return t.BaseType == typeof(MainSim);
}
</pre>
<p>Obviously <em>t.BaseType</em> is going to return <em>Sim</em> since <em>Type.BaseType</em> gets the type from which the current Type directly inherits. </p>
<p>Short of having to do <em>t.BaseType.BaseType</em> to get <em>MainSub</em>, is there any other way to get the proper type using .NET libraries? Or are there overrides that can be redefined to return the main class? </p>
<p>Thank you in advance</p>

What's the best way to have a variable be accessible from anywhere in your program?
|
<p>I'm making a game right now and pretty much everything has its own class. The main classes I feel that I have a problem with are my 'Level' and 'Object' class. The level class contains images to every image in the level, and the Object class contains the image for each object on the screen(an object is pretty much anything: your player, an enemy, an item, etc).</p>
<p>The way I have it right now is that the Object class has an Image and when you create a new object, you load a new image into it. So lets say you have two enemies that use the same image, both instances of the object will separately load the image and I'll have two of the same images in memory. This seems like a really bad idea and later when my game gets more complicated it will slow it down a lot.</p>
<p>So what I was thinking about doing is having something like a Resource Manager class that would hold all of the images, and than each object would just ask the resource manager for the image it needs. That way it would only store each image once and save some space.</p>
<p>I could probably easily do this with a static variable in the Object class, but since the Level class also needs to use images it would also need access to the Resource Manager. Would it be best to send a pointer to a resource manager to each instance of an object/level(or any other class I later make that would need it) and access it that way? Or would there be a better way to do this?</p>
