Redefine a method
|
<p>I have a class A which holds a collection of objects. Every instance of the class fills the collection according a different logic. From time to time I need to update all the collections.
I was thinking this could be done maybe if the class has a method that holds the logic for filling the collection and I can set this logic at the time of the creation of the object.
Like this:</p>
<pre><code>MyClass instance = new MyClass();
instance.updateCollection = { logic for filling the collection } //
</code></pre>
<p>The logic will be different for each object.</p>
<p>Thanks</p>

Optimizing the load time of presentModalViewController:
|
<p>In my NiB, I have several View controllers. When the app launches, all their corresponding ViewDidLoad() calls are called.</p>
<p>in ViewControllerA, I have ViewA that contains a UiScrollView with 100 pictures. In initalize these pictures in ViewdidLoad. So on app launch, all pictures are initalized.</p>
<p>In my Main Menu View Controller, I have a button that when pressed calls presentModalViewController:ViewControllerA </p>
<p>That call is taking 20 seconds. </p>
<p>I thought the pre loading in ViewDidload would optimize this. However, once the call returns and recalled (bringing up this VC the second time, its really quick and instant).</p>
<p>So what is causing this? Why is it taking so long the first time calling presentModalViewController. Internally, is it trying to arrange all the images? Any way of optimizing this? If not, whats the best way to show UiActivityIndicator</p>
<p>Thank you in Advance </p>

Working with Bundles in Android
|
<p>I have an app containing many functions, of course. On of my functions is returning two variables, one <code>int</code> and one <code>String</code>. I've figured out that the easiest way to return this variables is to put them in a <code>Bundle</code>, e.g like this:</p>
<pre><code>private Bundle returnInfo() {
Bundle result = new Bundle();
String something = "This is a test";
int number = 15;
result.putInt("number", number);
result.putString("string", something);
return result;
}
</code></pre>
<p>And in another function like this:</p>
<pre><code>private void getInfo() {
Bundle gotcha = returnInfo();
String gotSomething = gotcha.getString("string");
int gotNumber = gotcha.getInt("number");
}
</code></pre>
<p>This is just a part of my app, in fact this is just a mockup to show you my problem. Cause when I debug my app, the variables <code>gotSomething</code> and <code>gotNumber</code> contains <code>null</code>, but my Bundle <code>gotcha</code> contains <code>Bundle[{string=This is a test, number=15 }]</code> isn't this the way to solve my problem? </p>

threads reagarding notification
|
<p>I was going through threads and I read that ..The notify() method is used to send a signal to one and only one of the threads that are waiting in that same object's waiting pool.
The method notifyAll() works in the same way as notify(), only it sends the signal to all of the threads waiting on the object.</p>
<p>Now my query is that if Lets say I have 5 threads waiting and through Notify() , i want to send to notification to thread 3 only, what logic should be there that notification is sent to thread 3 only ..!!</p>

How to convert an array to a double so big array?

<p>I have an element type:</p>
<pre><code>public class FieldInfo

public string Label { get; set; }
public string Value { get; set; }
}
</code></pre>
<p>And I have an array filled with <code>FieldInfo</code> objects.</p>
<pre><code>FieldInfo[] infos = new FieldInfo[]
{
new FieldInfo{Label = "label1", Value = "value1"},
new FieldInfo{Label = "label2", Value = "value2"}

<p>Now I want to convert that array to a new one that contains following values:</p>
<pre><code>string[] wantThatArray = new string[] {"label1", "value1", "label2", "value2"};

<p>Is there a short way to do the conversion from an array like <code>infos</code> to an array like <code>wantThatArray</code>?<br>

Javascript displaying dynamic content

function showhide(t) {
var target = document.getElementById('bankingdetails');
if (target.style.display == 'none') {
var text = 'Please effect payment to the following account:<br />';
var accountnum = 'Account Number: 39485620346<br />';
var branchcode = 'Branch Code: 34985<br />';
var branchname = 'Branch: F00 Bank Whoville';
if (t == 0) {
// User opted for Online Payment
target.style.display = 'block';
target.innerHTML = 'Please click here to go to PayPal:<br /><a href="http://www.paypal.com">Go to PayPal</a>';
} else {
target.style.display = 'block';
target.innerHTML = text + accountnum + branchcode + branchname;
};
} else {
target.style.display = 'none';
};
};
</script>
<input type="radio" name="radPayment" onclick="showhide(0);" />Pay Online
<input type="radio" name="radPayment" onclick="showhide(1);" />EFT
</code></pre>
<p>Right now, I can click either radio button to display it's message, but... I have to click it again, or click on the other one to hide the visible message.</p>
<p>What I'd like is to change the text that displays on the page so that if the EFT text is visible, if I click on the Pay Online button, the text will change immediately.</p>

jQuery fadeTo delay in Webkit browsers
|
<p>I've implemented what I feel is a rather simple script on my menu. It works in Firefox and IE, but in Chrome and Safari, there is a delay of about a half-second. All it is doing is setting the opacity 60%, and then 100% on hover. Here's the code:</p>
<pre><code> $(document).ready(function() {
$(".NavMenu a").fadeTo('200', 0.6);
$(".NavMenu a").hover(function() {
$(this).fadeTo('200', 1.0);
}, function() {
$(this).fadeTo('200', 0.6);
});
});
</code></pre>
<p>Has anyone else experienced this, or know of a workaround? I've tested other sites in Webkit browsers and the fadeTo effect seemed fine.</p>

Why getHeight() of a Viewgroup does not change

<p>I have a LinearLayout (ViewGroup). And in my code, I have added a child view (another linear layout) to the LinearLayout. My question is why the LinearLayout 's getHeight() return the SAME value? On the phone, I do see my child linear layout is visible and is displayed correctly. But why the getHeight() does not return me the right value?</p>
<p>And I have looked at the source code of add() in ViewGroup. It does call 'requestLayout()' so I expect the getHeight() of the ViewGroup does get update correctly. Am I correct?</p>

Fix Javascript Value to 0 decimals
|
<p>I have this script which is working in formatting my currency but now its not fixing my value to 0 decimal places, Im new to javascript so could anybody explain where and hwo I'd do this? Thanks</p>
<pre><code>function FormatNumberBy3(num, decpoint, sep) {
// check for missing parameters and use defaults if so
if (arguments.length == 2) {
sep = ",";
}
if (arguments.length == 1) {
sep = ",";
decpoint = ".";
}
// need a string for operations
num = num.toString();
// separate the whole number and the fraction if possible
a = num.split(decpoint);
x = a[0]; // decimal
y = a[1]; // fraction
z = "";
if (typeof(x) != "undefined") {
// reverse the digits. regexp works from left to right.
for (i=x.length-1;i>=0;i--)
z += x.charAt(i);
// add seperators. but undo the trailing one, if there
z = z.replace(/(\d{3})/g, "$1" + sep);
if (z.slice(-sep.length) == sep)
z = z.slice(0, -sep.length);
x = "";
// reverse again to get back the number
for (i=z.length-1;i>=0;i--)
x += z.charAt(i);
// add the fraction back in, if it was there
if (typeof(y) != "undefined" && y.length > 0)
x += decpoint + y;

How to activate functionality only in developer mode

<p>I have application with in app billing. I'm using the <a href="https://github.com/robotmedia/AndroidBillingLibrary" rel="nofollow">AndroidBillingLibrary</a> to manage the purchase.</p>
<p>I would like to be able to have access to all the buyable option when i run the app in debug mode.</p>
<p>Currently when i need to test an option i replace something like this : </p>
<pre><code>bool option = BillingController.isPurchased(this,OPTION_NAME);
</code></pre>
<p>by</p>
<pre><code>bool option = true;//BillingController.isPurchased(this,OPTION_NAME);
</code></pre>
<p>Clearly not a good solution !</p>
<p>Is it safe todo something like this ? :</p>
<pre><code>public class MyApp extends Application {
public static final bool DEBUG = true;
}
if(MyApp.DEBUG)
option = true;
else
option = BillingController.isPurchased(this,OPTION_NAME);
</code></pre>

Mixing inline attributes with an attribute object
|
<p>I should get 3 images here but I get 2. The last one fails:</p>
<pre><code><!DOCTYPE html>
<html>
<head>
<script src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.5.1.js" type="text/javascript"></script>
<script type="text/javascript">
$().ready(function() {
var img = $('<img src="icon.next.gif" url="/" />');
$("body").append(img);
img = $('<img />', { src: "icon.next.gif", url: "/" });
$("body").append(img);
var img = $('<img src="icon.next.gif" />', { url: "/" });
$("body").append(img);
});
</script>
</head>
<body>
</body>
</html>
</code></pre>
<p>I could swear I've mixed these before but now it seems like the second parameter replaces all tags. I really need it to add because I've got a string generated (which comes with inline attributes) and I need to add to it.</p>
<p>Here's [<a href="http://jsfiddle.net/x2qSz/" rel="nofollow">fiddle</a>] for anyone who'd like to play with it.</p>
<p>Using IE9 and it breaks with:</p>

Android: extending PhoneBase?
|
<p>I know it is possible to use TelephonyManager to get information like: service state, device ID, Sim Operator, etc...
Is it possible to edit some of this information?</p>
<p>Couldn't find .set() functions on Android.com documentation but I've found the <a href="http://www.netmite.com/android/mydroid/frameworks/base/telephony/java/com/android/internal/telephony/gsm/GSMPhone.java" rel="nofollow">GSMPhone.java</a> source code which includes functions like .setNumber1Number() (used to set/edit the number?).</p>
<p>I basically want to know if it's possible to edit the phone number located on Sim card (Settings->About->Status->My Phone Number).</p>
<p>Appreciate any answer, even a simple "NO", if it's indeed impossible.</p>
<p>Thank you!</p>

fstream's getline() works for a little bit...and then breaks
|
<p>I have a text file with a bunch of numbers separated by newlines, like this:
123.25
95.12
114.12 etc...</p>
<p>The problem is, when my program reads it, it only copies the number to the array up to the second number and then fills the rest of the elements with zeroes. I've tried using delimiters and ignore statements but nothing has worked. Here's the code.</p>
<p>Edit(here's the whole program:)</p>
<pre><code>#include <iostream>
#include <string.h>
#include <iomanip>
#include <fstream>
using namespace std;
struct utilityInfo
{
char utility[20];
double monthlyExpenses[12];
};
int main(){
utilityInfo Utility[3];
char charray[100];
fstream inFile;
inFile.open("expenses.txt");
inFile.getline(charray, 7);
cout<<charray<<endl;
if(inFile.fail()) cout<<"it didnt work";
for(int i=0; i<12; i++)
{
inFile.getline(charray,20);
Utility[0].monthlyExpenses[i]=atof(charray);
}
for(int z=0; z<12; z++)
{
cout<<Utility[0].monthlyExpenses[z]<<endl;
}
inFile.close();
return 0;
}
</code></pre>
<p>Here's what the text file looks like:</p>
<pre><code>207.14
177.34
150.55
104.22
86.36
53.97
52.55
58.77
64.66
120.32
153.45
170.90
</code></pre>
<p>And here's what the output looks like:</p>
<pre><code>207.14
177.34

The correct way to modify an object that is being passed as a parameter into the modifying class
|
<p>What is the best way of the following 2 suggestions to modify a property on an object that is being modified by a class that accepts the object as a parameter?</p>
<ol>
<li>Have the class work on the object and a return a value which you then assign to the object</li>
</ol>
<p>or.</p>
<ol>
<li>Pass the object in using the ref keyword and have the class amend the object without actually returning anything.</li>
</ol>
<p>For example, I have a Person object with a First Name and Last Name and 2 different ways to create the Full Name.</p>
<p>Which is the best way? </p>
<pre><code>public static void Main()
{
Person a = new Person { FirstName = "John", LastName = "Smith" };
Person b = new Person { FirstName = "John", LastName = "Smith" };
NameProcesser np = new NameProcesser();
// Example A
a.FullName = np.CreateFullNameA(a);
// Example B
np.CreateFullNameB(ref b);
}
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
public string FullName { get; set; }
}
public class NameProcesser
{
public string CreateFullNameA(Person person)
{
return person.FirstName + " " + person.LastName;
}
public void CreateFullNameB(ref Person person)
{
person.FullName = person.FirstName + " " + person.LastName;

I have the following code: </p>

int main()
{
const int SIZE = 5;
float a[SIZE];
cout << "Enter " << SIZE << "numbers:\n";
for(int i = 0; i<SIZE; i++);
cin >> a[i];
sort(a,5);
cout << "In sorted order: ";
}
void sort (float a[], int n)
{
for (int i=1; i < n; i++)
for (int j=0; j < n-i; j++)
if (a[j] > a[j+1]) swap (a[j], a[j+1]);

Private Set or Private member?
|
<p>I was wondering what's considered the C# best practice, private/protected members with public getters, or public getters with private/protected setters?</p>
<pre><code> public int PublicGetPrivateSetter
{
get;
private set;
}
</code></pre>
<hr>
<pre><code> private int _privateMember;
public int PublicGetPrivateMember
{
get { return _privateMember; }
}
</code></pre>
<p>I feel that using a private member is more explicit in your code that it's a private setter (using naming conventions).
On the other hand using private setters gives you an option to use virtual (protected), write less code, has less room for mistakes and can give you an option to add a side effect later on if you need to.</p>
<p>I couldn't find what's considered a best practice, or even if one is considered better than the other. From what I've seen usually 80% of the time (from code that I'VE seen) people DONT use private setters... I'm not sure if this is because people don't know about private setters, or because it's considered better to actually use private members.</p>
<p>EDIT:</p>
<p>Indeed, other benefits which I forgot about when using private members is default values and the use of readonly.</p>

Using Mediaplayer to replay the same file
|
<p>Im hoping you can provide some guidance. I created a 'final' instance of a mediaplayer (mp1) and on a button click it plays a mp3 file. I then need to stop the file when I click a second button. This works fine until I try to play the file again - nothing happens. I think that because the mp1 instance is 'final', when I stop it, it stops for good until I relaunch the app. I dont want to pause the file, I want to stop it and then restart it afresh. Any ideas welcome. I tried putting the mp1 creation within the button. This worked until the app crashed - probably because multiple mediaplayer creations used all the device memory?</p>
<p>Thanks!!!</p>
<pre><code>// const mediaplayer
mp1 = MediaPlayer.create(getApplicationContext(), R.raw.mysound);
...
// in button 1
if (radSound1.isChecked()) {
radSound2.setChecked(false); // ...set radiobutton 2 to false
mp1.start(); // ...play the mp3 file
}
...
// in button 2
if (mp1 != null){
mp1.reset();
//mp1.setDataSource();
// mp1.prepare();
}
</code></pre>

Android - Rotate image around center point?

<p>How can I rotate a bitmap (not a view or canvas) around its center point when the user touches it and drags it?</p>
<p>I have tried loads of examples on stack overflow and none appear to work.</p>

rotation = (int) Math.toDegrees(r);

Can I change the temp folder path?
|
<p>I have an asp.net app that uses <code>System.IO.Path.GetTempFileName()</code> for temporary files. In the production IIS environment (W2K3), the temp folder (<code>System.IO.Path.GetTempPath()</code>) points to <code>C:\Windows\Temp</code>. But on my XP dev machine it's <code>C:\documents and settings\machinename\ASPNET\temp</code>. </p>
<p>Is it possible to change this folder without affecting other accounts on my machine?</p>

where to import the jquery.js file
|
<p>I was wondering where I should write the <code><script src="jquery.js"></script></code> in a php project.
I wrote it in the main file menu.phpm in the head and I then include this file in other files but if I do that the jquery functions I use don't work in the other files while if I add again <code><script src="jquery.js"></script></code> in the other file, it work.
Do I have to write that in every file in which I use jquery functions?</p>

jquery Have same div show on multiple hovers

<p>I have several divs of the same class that I want to show the same div whenever any of them are hovered over. I only want to create this second div once. I have tried creating it within the document and then cloning and appending it whenever I need it. This isn't working. In the example below, I main_item is the class being hovered over and optionbar is the div to show. Note that any main_item class is assigned an id of 9999 when you hover over it and the id is removed when you hover away from it.</p>
<pre><code>$(function(){
$(".main_item").hover(function(){
$('.optionbar').clone().appendTo("#9999");

stand alone application unable to connect to database
|
<p>We have a web based application which has web services (say user.asmx) which communicate with application database using generic credentials. In order to provide access to a user, we have an automation tool which uses the above web services and uses same credentials (as web application is using) and insert/update records in the application database.</p>
<p>Here, we have a concern that there is a logon trigger on the database and is preventing the tool to communicate to database. While investigating the error log on database, we found the below error message:</p>
<p>LOGON_TRIGGER: oerr, unhandled exception occurred</p>
<p>LOGON_TRIGGER: user =>abcdef</p>
<p>LOGON_TRIGGER: machine=></p>
<p>LOGON_TRIGGER: program=>W3WP.EXE</p>

<p>LOGON_TRIGGER: -20001</p>
<p>LOGON_TRIGGER: ORA-20001: abcdef@W3WP.EXE You are not allowed to login</p>
<p>DBA want us to investigate and get the machine name populated so that they can alter the trigger to allow this tool.</p>
<p>Can experts please advise what could be the reason that machine name is not populating at the database level.</p>

interface variables are final and static by default and methods are public and abstract
|
<p>The question is why it's been decided to have variable as final and static and methods as public and abstract by default.</p>
<p>Is there any particular reason for making them implicit,variable as final and static and methods as public and abstract.</p>
<p>Why they are not allowing static method but allowing static variable?</p>
<p>We have interface to have feature of multiple inheritance in Java and to avoid diamond problem. But how it solves diamond problem,since it does not allow static methods.</p>
<p>In the following program, both interfaces have method with the same name..but while implementing only one we implement...is this how diamond problem is solved?</p>
<pre><code>interface testInt {
int m = 0;
void testMethod();
}
interface testInt1 {
int m = 10;
void testMethod();
}
public class interfaceCheck implements testInt, testInt1{
public void testMethod() {
System . out . println ( "m is"+ testInt.m );
System . out . println ( "Hi World!" );
}

Email or Database?

<p>I`m making a site where users have to sign up. They will be contacted later once the site is ready.</p>
<p>Right now, I have a simple plugin that creates a form and sends me the contact info via email of anyone who signs up. </p>
<p>Is this a stupid plan? Should I have a form that submits the information to a database? or can the contact info be easily exported from gmail later when needed?</p>
<p>If you think a database is a better solution, can you recommend a simple PHP script with the necessary filters.</p>

Android XML Composite View
|
<p>I'm new to Android development, and am having a tough time working something out. I want to make a composite view (called SkillDiceGroup) of a TextView, EditText, and SkillDiceButton (which is an extension of the Button class). I have it working when declaring my SkillDiceGroup as pure code, and putting this in my XML layout:</p>
<pre><code> <com.jeremybush.d20.SkillDiceGroup android:id="@+id/skillDiceTest"
android:title="Foobar!"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</com.jeremybush.d20.SkillDiceGroup>
</code></pre>
<p>And I have this code:</p>
<pre><code>public class SkillDiceGroup extends LinearLayout
{
// The View components
private TextView mTitle;
private EditText mSkill;
private SkillDiceButton mDice;
public SkillDiceGroup(Context context, AttributeSet attrs)
{
super(context);
this.setOrientation(HORIZONTAL);
mTitle = new TextView(context);
mTitle.setText("foobar");
addView(mTitle, new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
));
mSkill = new EditText(context);
addView(mSkill, new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
));
mDice = new SkillDiceButton(context, attrs);
mDice.setText("d20");
addView(mDice, new LinearLayout.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT
));
}
private class SkillDiceButton extends DiceButton
{
public SkillDiceButton(Context context, AttributeSet attrs) {
super(context, attrs);
}
public void onClick(View view)
{
modifier = Integer.parseInt(mSkill.getText().toString());
super.onClick(view);
}
}
}
</code></pre>
<p>This works how I want it, but I would like to declare the three items in the xml view on their own. How can I do this?</p>

Best Way to Avoid Errors due to Settings/Configuration BEFORE Runtime
|
<p>A common problem is that programs may compile ok, but external (user/environment) settings may cause applications to crash during runtime.</p>
<p>Aside from performing checks all over the code, (alas actually performed during Runtime),
I would like to have rule sets to assert <strong>during build</strong> that, at least default values settings, are coherent.</p>
<p>The simplest case may be, if default settings are hardcoded : </p>
<pre><code>Directory defaultDir = new Directory("D:\\Data");
UserLogin usr1 = "Jesse";
UserLogin usr2 = "James";
</code></pre>
<p>(yeah, "Booh"; this is an example, please <strong>DO NOT</strong> comment/answer on that unsignificant detail... I know it's hard for some of you, but please REFRAIN ! :-) )</p>
<p>So, is there a SIMPLE way to check DURING Build, that "D:\Data" exists, and that usr1 and usr2 do have different login strings etc...</p>
<p>I am sure there are assertion mechanisms in .Net, and maybe Unit Testing (I'd rather avoid the latter cause it may be oversized for the very light usage/need in this particular case. But I guess that's what Unit Tests are designed for too...)</p>

android:id = "@+id/button1"
android:layout_width = "wrap_content"
android:layout_height = "wrap_content"
android:text = "Next Activity"

<p>And in my R.java:</p>
<pre><code>public static final class id {
public static final int button1=0x7f050000;
}
</code></pre>
<p>Why I get and error saying that my button is a view when it actually is indeed a button... is a mystery.</p>

In PHP, how do we return a large array?
|
<p>Say if this is the code:</p>
<pre><code>function bar() {
$result = array();
for ($i = 0; $i < 1000; $i++) {
$result[] = $i * 10;
}
return $result;
}
$ha = bar();
print_r($ha);
</code></pre>
<p>Is it not efficient to return a large array like that since it is "return by value"? (say if it is not 1000 but 1000000). So to improve it, would we change the first line to:</p>
<pre><code>function &bar() {
</code></pre>
<p>that is, just by adding an <code>&</code> in front of the function name -- is this a correct and preferred way if a large array is returned?</p>

} catch (Exception e) {
throw new ServiceLoadException(serviceName + "not loaded");
}
}
private String getImplName (String name) throws Exception {
java.util.Properties props = new java.util.Properties();
java.io.FileInputStream fis = new java.io.FileInputStream("properties.txt");
props.load(fis);
fis.close();
return props.getProperty(serviceName);
}
}
</code></pre>
<p>This should be really simple - but I keep getting two errors - IService cannot be resolved to a type (on both the factory and the service) and also an serviceName cannot be resolved into a variable error in the factory. I know I am missing something simple...</p>

CompleteWizardStep not working as should be - Why?
|
<p>I am trying to create a website which will allow users to register, log in, change password, etc.</p>
<p>Currently i am creating the register process, and i am doing this by using a custom CreateUserWizard in order to avoid the default buttons that it inserts.
I have successfully created the custom CreateUserWizardStep and when i run the page from VS 2010, i see all the controls on the webpage, that is, Username, email, password, etc textbox-controls. Everything looks as supposed to look.</p>
<p>I didn't want to use the default Create User button that the CreateUserWizard control inserts, and so i put an asp button with ID="Next" Text=Create User and CommandName=MoveNext</p>
<p>Note that I still haven't written code to store the user's credentials in the database yet. I don't want to do that yet. </p>
<p>I also have created the CompleteWizardStep,which follows the CreateUserWizardStep, containing an asp Literal saying that the account was created successfully, when the account will be created, that is when i will also implement the storing of user's credentials into the database that i have created, cause i don't want to use the default one that the .NET framework provides. I will use SQLMembership Provider, but my own database.</p>
<p>When i click the Create User button (i remind that is not the default button of the CreateUserWizard , but an asp button that i inserted), the message in the CompleteWizardStep control doesn't show up at all on the browser. So i assumed that the CompleteWizardStep control is not working. </p>
<p>**And my question is why is this happening?
Is it because i haven't implemented yet the storing of data into the database and that way the CreateUserWizard control detects this fact and doesn't move to the CompleteWizardStep ?
If so, how the CreateUserWizard control detects that the data were stored successfully into the databse?
Shouldn't the CompleteWizardStep control run immediately after the Create User button is clicked?</p>
<p>If not so, what am i doing wrong?**</p>
<p>If you need code sample i can provide it, but i didn't do so because this is more like a general question i am putting here.</p>
<p>Thank you in advance ! </p>
