Using a pre-defined method to change a property of an object Javascript
|
<p>I have a function which is defined before the object was created. This pre-defined function uses the 'this' keyword to change the value of a property in the object. Inside the object I have a method that calls the predefined method with one argument. However after calling this method and I try to print the value of the property that was supposed to be changed, it still remains the same. How do I fix this?</p>
<pre><code>var setName = function(yourName){
this.name = "Your name is " + yourName;
};
// create an object called `human`
var human = {
name: "Nothing here yet",
setHumanName: function(name) {
setName(name);//Name should be changed now
}
};
human.setHumanName("Emeka");
console.log(human.name); //this does not print the new value of name

When is the function executed when using jQuery .each()?
|
<p>Given the following jQuery expression</p>
<pre><code> $("form").each(function () {
var info = validationInfo(this);
if (info) {
info.attachValidation();
}
});
</code></pre>
<p>The selector chooses all forms on the page, and then for each 'form' found, it attaches a function.</p>
<p>My question is when does the JS in this function actually run? Does the JS in the function execute when it is attached?</p>

Cluster member variables declaration by their type useful or not?
|
<p>Please have a look a the following code sample, executed on a Windows-32 system using Visual Studio 2010:</p>
<pre><code>#include <iostream>
using namespace std;
class LogicallyClustered
{
bool _fA;
int _nA;
char _cA;
bool _fB;
int _nB;
char _cB;
};
class TypeClustered
{
bool _fA;
bool _fB;
char _cA;
char _cB;
int _nA;
int _nB;
};
int main(int argc, char* argv[])
{
cout << sizeof(LogicallyClustered) << endl; // 20
cout << sizeof(TypeClustered) << endl; // 12
return 0;
}
</code></pre>
<hr>
<h1>Question 1</h1>
<p>The <code>sizeof</code> the two classes varies because the compiler is inserting padding bytes to achieve an optimized memory allignment of the variables. Is this correct?</p>
<h1>Question 2</h1>
<p>Why is the memory footprint smaller if I cluster the variables by type as in <code>class TypeClustered</code>?</p>
<h1>Question 3</h1>
<p>Is it a good rule of thumb to always cluster member variables according to their type?
Should I also sort them according to their size ascending (bool, char, int, double...)?</p>
<p><strong>EDIT</strong></p>
<h1>Additional Question 4</h1>
<p>A smaller memory footprint will improve data cache efficiency, since more objects can be cached and you avoid full memory accesses into "slow" RAM. So could the ordering and grouping of the member declaration can be considered as a (small) but easy to achieve performance optimization?</p>

Reduce volume of received call's ringtone?

<p>I want to lower the volume in in-call mode
So I tried this code:</p>
<pre><code>AudioManager audio = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
audio.setStreamVolume(audio.STREAM_VOICE_CALL, -1, 0);
</code></pre>
<p>But In-call volume is set to 0 and still loud.
Have any idea? I don't want to set the mode of ringtone to silent, just turned down.</p>

java exception handling and continuation

<p>I have a Java Program where I get data from a different source. some times while reading I see Exception and the program is exiting.
Mine is in a program that runs every 10minutes.</p>
<pre><code>Public static void main(Strings[] args)
{
...readsource();
}
Private static void readsource() throws IOException
{
...
}
</code></pre>
<p>Issue:
I am able to get/See the Exception. But I want the program to continue
To that what is the best logic? I dont see try-catch-finally also is not addressing ..I want the program to continue even after seing the exception (I mean the next iteration should continue). This looks to be a Basic issue not sure how to address this...</p>

zlib inflate error : Z_DATA_ERROR randomly
|
<p>I have an application that compresses and sends data via socket and data received is written in remote machine. During recovery, this data is decompressed and retrieved. Compression/Decompression is done using "zlib".But during decompression I face the following problem randomly:</p>
<p><strong>zlib inflate() fails with error "Z_DATA_ERROR" for binary files like .xls,.qbw etc.</strong></p>
<p>The application compresses data in blocks say "1024" bytes in a loop with data read from the file and decompresses in the same way.From the forum posts, I found that one reason for Z_DATA_ERROR is due to data corruption. As of now, to avoid this problem, we have introduced CRC check of data compressed during send and what is received.
Any possible reasons on why this happens is really appreciated! (as this occurs randomly and for the same file, it works the other time around).Is it bcoz of incorrect handling of zlib inflate() and deflate() ?
<strong>Note: If needed,will post the exact code snippet for further analysis!</strong></p>
<p>Thanks...Udhai</p>

Storing "binary" data type in C program
|
<p>I need to create a program that converts one number system to other number systems. I used itoa in Windows (Dev C++) and my only problem is that I do not know how to convert binary numbers to other number systems. All the other number systems conversion work accordingly. Does this involve something like storing the input to be converted using %?</p>
<p>Here is a snippet of my work:</p>
<pre><code>case 2:
{
printf("\nEnter a binary number: ");
scanf("%d", &num);
itoa(num,buffer,8);
printf("\nOctal %s",buffer);
itoa(num,buffer,10);
printf("\nDecimal %s",buffer);
itoa(num,buffer,16);
printf("\nHexadecimal %s \n",buffer);
break;
}
</code></pre>
<p>For decimal I used %d, for octal I used %o and for hexadecimal I used %x. What could be the correct one for binary? Thanks for future answers!</p>

How to communicate back to a service from a broadcast receiver?
|
<p>Hope someone can help me out here. I will try to be concise!</p>
<p>I have a widget which starts a service. The service registers two broadcast receivers. I would like to send back intents from the receivers to the service, so that the service can react.</p>
<p>I believe I read somewhere that 'starting' the service multiple times works, e.g. do the following in the receivers:</p>
<pre><code>serviceIntent.setAction("me.SERVICE");
intent.putExtra("me.SERVICE", somedata);
context.startService(serviceIntent);
</code></pre>
<p>I remember reading (on some blog) that this won't start a new service, but will simply pass the intent to the already running service. Is this correct? Is it a bad way of doing it? Is there a better way?</p>
<p>Thanks very much!</p>

Provide implementation to pure virtual function through multiple inheriting another class

<p><strong>Possible Duplicate:</strong><br>
<a href="http://stackoverflow.com/questions/3291568/import-a-definition-of-a-function-from-a-base-class-to-implement-abstract-inte">“import” a definition of a function from a base class to implement abstract interface (multiple inheritance in C++)</a> </p>
</blockquote>
<p>Suppose I have a base class</p>
<pre><code>struct Base1 { virtual void f() = 0; };
</code></pre>
<p>and another class that provides implementation for function <code>f</code>:</p>
<pre><code>struct Base2 { virtual void f() {} };
</code></pre>
<p>I wanted to use <code>Base2::f</code> to implement <code>Base1::f</code> through multiple inheritance:</p>
<pre><code>struct C : Base1, Base2 {};
</code></pre>
<p>But look like compiler doesn't do what I expected, and <code>C</code> is still abstract.</p>
<p>So what is the best way to provide implementation to a pure virtual through another class?</p>
<p>Thanks.</p>

Garbage appears in vector after inserting result of operator
|
<p>I have an object with an operator defined like this:</p>
<pre><code>P& operator +(const P &rhs) {
return P(x + rhs.x, y + rhs.y, z + rhs.z);
}
</code></pre>
<p>It does not have custom copy or assignment operators.</p>
<p>After I assign directly the result of an addition inside the vector, garbage appears inside it.</p>
<pre><code>P p1(1.0, 0.0, 0.0);
P p2(0.0, 0.0, 0.0);
vector<P> v(1);
v[0] = p1 + p2; // v[0] now contains garbage.
</code></pre>
<p>If I do it through a variable, everything is as expected.</p>
<pre><code>vector<P> u(1);
P q = p1 + p2;
u[0] = q; // u[0] contains correct value.
</code></pre>
<p>What can be the reason for such behavior? What is the difference between the two cases?</p>

Why swap don't use Xor operation in C++
|
<p>I've learned that Xor operation can be used to implement effective swap function. like this:</p>
<pre><code>template<class T>
void swap(T& a, T& b)
{
a = a^b;
b = a^b;
a = a^b;
}
</code></pre>
<p>But the implementation of swap all i can found on the internet is essentially like this:</p>
<pre><code>template<class T>
void swap(T& a, T& b)
{
T temp(a);
a = b;
b = temp;
}
</code></pre>
<p>It seems that the compiler didn't generate the same code for the two form above because I tested it on VC++ 2010 and the first one is done the job more quickly(and is more quickly than std::swap). Is there portable or any other problem with first one? Feel free to correct any of my mistake cause i'm not an English native and not good at C++.</p>

WebBrowser control manipulation
|
<p>I use a webbrowser control in C# to input text into forms, click on forms, etc to automate some tasks. But with a webbrowser control it takes forever for pages to load. How can I speed things up. Is it possible to login to a website using webrequest? I know it can post data but will it consider it to be logged in. If I used a webclient control and downloaded the source code to a web page. Will it download the normal page or the logged in page?</p>
<p>Also whenever I download a page using webclient, certain elements dont load (some images/forms) unless the page was accessed in a browser. Is there a way around that?</p>
<p>@John Saunders
Its not the wpf version.
I navigate to websites with the Navigate function, from there I can access elements in the page such as:</p>
<pre><code>HtmlElementCollection links = webBrowser.Document.GetElementsByTagName("a");
if(links[index].InnerText == "some link value")
links[index].InvokeMember("click");
</code></pre>
<p>That is some pseudo code for following a specific link on a page.
Its just too slow. Takes easily 10-20 seconds for a page to load.</p>

Looking for javascript techniques
|
<p>I'm trying to learn some fresh and hacky javascript techniques and on my quest to do so, here is a function I mocked up:</p>
<pre><code>function doAction(index) {
for(var a = Array.prototype.slice.call(arguments, 1),
i = 0, r = [], l = a.length; i < l; i++)
r.push(a[i][index]);
return r;
}
doAction(2, ['a','b','c'],['a','b','c'],['a','b','c']) //==> ["c", "c", "c"]
</code></pre>
<p>This is basically what it does: get every nth element from a number of arrays and return them in a new one.</p>
<p>I would like to improve this function with freaky ninja-style ideas, not necessarily shorten the code, but rather optimize it. (You most probably already noticed the infamous <code>Array.prototype.slice</code> thingy);</p>
<p>As English is not my native tongue, I would also like a decent name for the action performed by this function. Thanks in advance guys (and women!)</p>
<p>Oh, here's a Fiddle: <a href="http://jsfiddle.net/Exv7Z/" rel="nofollow">http://jsfiddle.net/Exv7Z/</a></p>
<p>EDIT: Talking about optimizing things... (Idea from the genius in the comments)</p>

return Array.prototype.slice.call(arguments, 1).map(function(b) {
return b[index];
});

Using PDO for Data Management
|
<p>This question is more a design oriented question than a code specific question. I am new to PHP and I am planning to use PDO as a data access layer. Say for instance I have a class called CITY. Now if I need to create an instance of this class, what is the best technique. </p>
<ul>
<li>Should have a singleton DB access class which is used to write and read data from the db layer. </li>
<li>OR should I delegate it to the individual class object. For example if I invoke city.save() (city is a class), then the city class will handle the saving of that city object's data into the database. </li>
</ul>
<p>Excuse my ignorance but i have a java background and therefore trying to understand what is the best design principle for data management when using php. </p>

C# classes - Why so many static methods?
|
<p>I'm pretty new to C# so bear with me.</p>
<p>One of the first things I noticed about C# is that many of the classes are static method heavy. For example...</p>
<p>Why is it:</p>
<pre><code>Array.ForEach(arr, proc)
</code></pre>
<p>instead of:</p>
<pre><code>arr.ForEach(proc)
</code></pre>
<p>And why is it:</p>
<pre><code>Array.Sort(arr)
</code></pre>
<p>instead of:</p>
<pre><code>arr.Sort()
</code></pre>
<p>Feel free to point me to some FAQ on the net. If a detailed answer is in some book somewhere, I'd welcome a pointer to that as well. I'm looking for the definitive answer on this, but your speculation is welcome.</p>

Android apk won't install from the market nor web server
|
<p>This is my own application developed with the intention of distributing it via the Android market. It's been tested on several handsets, installed each time with from the SDK (so, adb).
However that appears to be the only way I can install it:</p>
<ul>
<li>I signed the application and uploaded it to my own server.</li>
<li>Any previous version is uninstalled from the device:</li>
<li>Downloading via the browser results in a silent fail. Server logs show that there was only one access (a successful OTA install requires, I believe, two request/responses). There is nothing at all in Logcat.</li>
<li>I tried instead releasing it to the Android Market. This time Logcat indicates a server-side error:

<p>The most likely problem, then, is how I signed the application. However the signed version can be installed via adb on the command line and even from gmail. Furthermore I signed a small, unrelated application with exactly the same results. I've also tried building from another machine and under Windows and Linux. Same results every time, on three different devices, factory reset, over the internet or WIFI. The only constant is me.</p>
<p>I've read literally every thread on stackoverflow regarding the above error in Logcat, all of which appear to be unrelated because I have no difficulty installing other applications from the Android market.</p>
<p>I've exhausted my meagre wits trying to debug this and would be very grateful for any ideas.</p>

Process and Task in Android
|
<p>Can someone let me know what is the difference between process and task in android.
As far as I understand whenever you lanuch an application, it will run in a seperate process. Am I Right? <br />
An application can contain multiple activities which can be run in same or different process. <br />
A Task is a set of activities (orederly). <br />
A process can contain multiple tasks. <br />
Please differentiate the two.</p>

Find connected device to Galaxy Tab - Android

<p>I'm developing an app in which I must start a slideshow with some picture info. So far, so good. There's only one issue: I need to show one type of view when the device (galaxy tab) is connected to a TV (TV-Out) and another view if it's showing on the tab.</p>
<p>Example:</p>
<p>If is connected to TV: Show only the images on TV, no info.
If is not connected to TV: Show images plus info.</p>
<p>How can I find out if the device is plugged to a TV?</p>

Difference between Server.MapPath and Page.MapPath

<p>What is the difference between those two?
If I only want to retrieve the absoluate path to an image on web server, is Server.MapPath safer in any case?
I'm using Page.MapPath right now, but it won't work if control was created in WebService since control.Page property become null?
Whether Server.MapPath always work?</p>

How do I get the path of a binary in c#?
|
<p>For some reporting purposes I'm trying to get the location of a certain binary.</p>
<p>I was doing this, and it was working, but I'm now getting a NullReferenceException when I try to get testProc.MainModule.FileName; and I think it may be that the program is closing before I'm able to grab it. Is there any better way to do this?</p>
<pre><code>ProcessStartInfo testPSI = new ProcessStartInfo(RunOptions.TestBinary);
testPSI.RedirectStandardError = true;
testPSI.RedirectStandardOutput = true;
testPSI.UseShellExecute = false;
Process testProc = new Process();
testProc.StartInfo = testPSI;
testProc.Start();
ret = testProc.MainModule.FileName;
testProc.Kill();
if (ret != null)

<p>Essentially, a very large number. Now, why does it output <code>241872</code>? I know PHP has float handlers. When I remove the leading zero, it functions as expected. What is that leading zero signifying?</p>

Javascript: How do I code a script where the user inputs a number and it returns three other numbers?
|
<p>I'm not even quite sure how I can make myself clear and I do apologize... but I have been searching all over the internet for a similar JavaScript code and I'm not even quite sure how to phrase the question ...</p>
<p>Basically, I want the user to input one thing, and I want something else to pop up.</p>
<p>As an example, the user would type in a number, let's say "10" into a text field or drop-down menu and then three other numbers would pop up, such as 15.25, 16.50, and 17.75 (either in pop window form, or just in a plain sentence, or in other text fields ... it doesn't really matter).</p>
<p>What I'm doing is I want to post an estimate calculator for loan payments on a website (with options for 30 day, 60 day, and 90 day payoff options).</p>
<p>There's no math involved in this code whatsoever (I understand if I have to input a lot of numbers - I already have those!). I don't want to create a calculator, because I think a calculator would be more complicated (I'm aiming for simple!) ... The loan fees and interest vary from one group of numbers to another, so if it were to be a calculator the script might get really complicated (because we're not looking at a easy 1 + 1 = 2 equation ... it's more like 1 + 1.50 + 1.00 = 3.50, or 10.00 + 4.00 + 1.25 = 15.25, or even 30.00 + 6.00 + 1.75 etc., there's no consistency).</p>
<p>So I'm figuring a simpler way around this beast would be to have the numbers readily available, with no calculations. So if they enter in a 1, the result they would get be 3.50, 4.50, and 5.50.</p>
<p>I don't know, that might be asking a bit much too....</p>
<p>Thank you in advance for your time and help.</p>

Generating objects and putting into arraylist with no duplicates
|
<p>Hi I am figuring out why this code is not working the way how i wanted it to work..</p>
<p>What i basically want is a random object that has a char and an int generating and putting it into an arraylist. However if the generated matches the same in the arraylist it must regenerate the number again and check to see if it exists. If it does not exist it will then be added into the arraylist.</p>
<pre><code> private final char letter;
private final int num;
private static Collection<RegistrationNumber> REGISTRATION_NUMBER = new ArrayList<RegistrationNumber>();
private RegistrationNumber(){
Random rand = new Random();
this.num = (1+(rand.nextInt(3)));
this.letter = Character.toUpperCase((char)(rand.nextInt(1)+'a'));
}
public static RegistrationNumber getInstance(){
boolean foo = false;
RegistrationNumber rn = null;
while(!foo){
rn = new RegistrationNumber();
if(!REGISTRATION_NUMBER.contains(rn)){
REGISTRATION_NUMBER.add(rn);
foo=true;
}
}return rn;
}
</code></pre>
<p>Once I look through the arraylist, there are still some repeating for example [A1,A1,A2] or [A2,A2,A3] </p>
<p>Many thanks!</p>

Finding objects in JS array and storing names to new array?

I want to store these dates in an array for later use and objects are, apparently, not found in an array by array[i], so how do I iterate through the array and just save the names to a string in another array?</p>

var dPTmp = [];
var i = 0;
for (var id in dP) {
dPTmp[i] = dP[id].toString();
i++;

Escape sequences from an integer

<p>I am writing an application to communicate with a serial device and I need to send the length of a string field in the string that is written to the serial port.
For example <code>"\x00\x27"</code> would be 27 bytes, and if I send this in the string it works as everything is hard coded so I know the length.</p>
<p>Another example is <code>"\x01\x27"</code> would be 127 bytes.</p>
<p>The problem is I need to be able to send variable length string fields. I know I can get the length using </p>
