How do I improve my style of JavaScript coding?
|
<p>My style of coding, I would say, is weak from a structural point of view. I can never conform my code to a style suitable for reuse or maintainability. I can't code exactly as you'd take a "professional's" code to be. And now I would like to start learning how to improve my style of coding that can match that of professionals. Do you have any resources that could help me out? Thanks.</p>

Randomly NoneType object is not callable error

<p>Python 2.7 32-bit</p>
<p>It's wired, because this showed up after ~1000 iterations, with out any previus problem.
This application scans online store to get current prices.
Firstly I thought that somewhere I missed someting, and as result there is <code>None.encode('utf-8')</code>, but no, and "".encode('utf-8') seems to work. Moreover, I can't reproduce this error on testing site, just sometimes shows up while hard-working with ~2500 products.
What are possible other sources of this error?</p>

How do I display the Java console?
|
<p>I'm aware of the fact that you can set it to "show" in the Java control panel, but that's not what I'm asking about. I'm curious about the other options... "Do not start" is pretty straightforward, but what about "Hide"? That would seem to imply that it is indeed running. If so, how can I make it show on demand from the hidden state?</p>
<p>Reason: It's annoying to have it open ALL the time, hoping there's a way to (preferably via keystroke) bring it from "hidden" to "shown" state for occasional debugging.</p>

How search number within range formatted string using delimiter?

<p>If my formatted string is:</p>

$min = min($arr);
$max = max($arr);

Is there any overhead with referencing static functions as part of a class definition?
|
<p>I am currently implementing some utility functions for implementing some libraries I am working on. I was forced to choose between segmenting the functions as static members as part of a class definition within a more general namespace, or enter more specific namespace and then define the functions. I choose the former feeling as it was more flexible in the way those utility classes may be drawn into scope (using or inheritance) though I was unsure whether there was any overhead associated with this design choice or not:</p>
<p>Is</p>
<pre><code>namespace Utilities {
struct CharUtil {
static void foo();
}
}
Utilities::CharUtil::foo();
</code></pre>
<p>slower than</p>
<pre><code>namespace Utilities {
namespace CharUtil {
void foo();
}
}
Utilities::CharUtil::foo();
</code></pre>
<p>?</p>
<p>Is the former faster using inheritance?</p>

OOP in Python!! My First assignment in Python
|
<p>I have no clue how OOP works in Python. I tried to get ideas from online tutorials but I couldn't understand clearly and my due date for this assignment is tomorrow morning. :(
I would really appreciate if you guys could help me in solving this!</p>
<blockquote>
<h3>Question 1:</h3>
<p>Write a class named Car that has the following data attributes:</p>
<ul>
<li><code>__year_model</code> (for the car's year model)</li>
<li><code>__make</code> (for the make of the car)</li>
<li><code>__speed</code> (for the car's current speed)</li>
</ul>
<p>The Car class should have an <code>__init__</code> method that accept the car's year model and make as
arguments. These values should be assigned to the object's <code>__year_model</code> and <code>_make</code> data
attributes. It should also assign 0 to the <code>__speed</code> data attributes.</p>
<p>The class should also have the following methods:</p>
<ul>
<li><code>accelerate</code><br>
The accelerate method should add 5 to the speed data attribute each time it is called.</li>
<li><code>brake</code><br>
The brake method should subtract 5 from the speed data attribute each time it is
called.</li>
<li><code>get_speed</code><br>
The get_speed method should return the current speed.</li>
</ul>
<p>Next, design a program that creates a Car object and then calls the accelerate method five
times. After each call to the accelerate method, get the current speed of the car and display
it. Then call the brake method five times. After each call to the brake method, get the current
speed of the car and display it.</p>

How does Python distinguish callback function which is a member of a class?
|
<p>Please look at the simple example:</p>
<pre><code>class A:
def __init__(self, flag):
self.flag = flag
def func(self):
print self.flag
a = A(1)
b = A(2)
callback_a = a.func
callback_b = b.func
callback_a()
callback_b()
</code></pre>
<p>The result is:</p>
<pre><code>1
2
</code></pre>
<p>It runs as expected. But I have a question. In C, the callback function is passed as a pointer. In Python, it should have a similar way to do this, so the caller knows the address of the function. But in my example, not only the function pointer is passed, but also the parameter (self) is passed, because the same method of the same class prints different results. So my questions are:</p>
<ol>
<li><p>Does such a method in Python only has one copy in memory? My meaning is that the code of any method only has one copy, and in my example the method won't be cloned itself. I think it should have only one copy, but here I still make this question in order to get more inputs.</p></li>
<li><p>I remember everything in Python is an object. So in my example, are there two function instances with different parameters but only one copy of code?</p></li>
</ol>

How to ensure that one time is always less than another
|
<p>I've got two times that need to be stored into a database. The time format is hh:mm:ss with NO DATE. These times can be changed by the users on the system. One is a time on and the other is a time off. The time off should always be greater than the time on within a 24 hour cycle.</p>
<p>Here is the part that I'm having trouble with. I don't want to limit the user to selecting times before midnight to keep everything in the same "daily" cycle so I'd like to be able to logically determine if the users' times are simply within a 24 hour time period and then test that the on time is always less.</p>
<p>Can someone help me work through this? There are so many time and date functions that I really don't know which one(s) I need to do this; plus, I'm unclear on how I should test for this.</p>
<hr>
<p>I'm starting to think that there is no way to test for this without having a date included. Just the times is not enough.</p>

Javascript Game Engine

<p>I'm trying to write a javascript game engine myself. I did something like this;
How do you think can make it more useful? Waiting for suggestions. thanks</p>
<p>How do I write less than this initial code, for example?</p>
<pre><code> var jSgame = function(w,h,bgcolor){
if(bgcolor == undefined){
bgcolor = '#ccc';
}
this.bgcolor = bgcolor;
if(w==undefined){
w = 400;
}
if(h==undefined){
h = 200;
}
this.w = w;
this.h = h;
this.start = function(){
var c = document.createElement('canvas');
if(c){
c.style.backgroundColor = this.bgcolor;
c.width = this.w;
c.height = this.h;
document.body.appendChild(c);
this.ctx = c.getContext('2d');
}
}
}
jSgame.prototype.draw = function(x,y,bgcolor){
a = new jSgame(x,y,bgcolor);

Problem finding/reading a file
|
<p>I'm trying to develop a small application, where I was given a JSON file, and I have to extract data from it. As I understood a JSON object takes a string argument, thus I'm trying to access a file and write the data from it to a string.
I've placed that file in a "JSON file" folder, and when I try to read the file, it throws me a file not found exception.
I've tried several ways to find a path to that file, but every attempt was for vain.
It might be that I'm extracting the path wrong, or might be something else, please help me.
Thanks in advance.
here is the code of finding the path:</p>
<pre><code> try
{
path = Environment.getRootDirectory().getCanonicalPath();
}
catch (IOException e)
{
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
File jFile = new File(path + /"JSON file/gallery.json");
</code></pre>
<p>here is the code for reading from a file :</p>
<pre><code> String str ="";
try
{
BufferedReader in = new BufferedReader(new FileReader(jFile));
while ((str += in.readLine()) != null)
{
}
in.close();
}
catch (IOException e)
{
e.getMessage();
}
return str;
</code></pre>
<p>Here more specification:
I want to take the data from the file in order to do that : JSONObject(jString).
when I extract the path of json file I create a file with the path and pass it to the function that reads from the file, and there it throws me a file not found exception, when I try to read from it.
The file does exists in the folder (even visually - I've tried to attach an image but the site won't let me, because I'm new user)
I've tried to open the file through the windows address bar by typing the path like that:
C:\Users\Marat\IdeaProjects\MyTask\JSON file\gallery.json and it opens it. </p>

Google Chrome, text input value
|
<p>I have an authentication system in my program, and when I did 'Save Password' with google chrome, it automatically fills the username and password text boxes with the last username and password that was saved.</p>
<p>However, when I try to check the value of the content of the username input box, using:</p>
<pre><code>alert($('#user_email').val());
</code></pre>
<p>Google Chrome gives me blank output, while Firefox gives me the value in the text box. Is there a way to get this value for Google Chrome as well? Maybe using something other than <strong>.val()</strong>?</p>
<p>Thanks.</p>

ASP.NET, refresh dropdownlist2 when dropdownlist1 selection changes?
|
<p>I have two databound dropdownlist controls. The first one (dropdownlist1) pulls directly from a table. The second one (dropdownlist2) also pulls from a table, but uses the selected value from dropdownlist1 in it's WHERE clause.</p>
<p>How do I update/refresh dropdownlist2 after the user makes a selection in dropdownlist1? (Using VB if done by code)</p>
<p>I've tried setting the "Auto Postback" property of dropdownlist1 to "true" and ultimately, this approach works. The only problem is, if I keep changing the selection in dropdownlist1, the selections available in dropdownlist2 are duplicated.</p>
<p>Both dropdownlist controls are contained within a CreateUserWizard control using template. I've tried using FindControl and then DataBind() on dropdownlist2 from the SelectedIndexChanged event of dropdownlist1, but no change occurs after a selection is made in dropdownlist1.</p>
<p>Any ideas?</p>
<p><strong>SelectedIndexChanged Event</strong></p>
<pre><code>Protected Sub AssignedManager_SelectedIndexChanged(sender As Object, e As System.EventArgs)
CreateUserWizard1.CreateUserStep.ContentTemplateContainer.FindControl("AssignedSupervisor").DataBind()
End Sub
</code></pre>
<p><strong>* Above, AssignedManager is the first dropdownlist and AssignedSupervisor is the second dropdownlist *</strong></p>

method getInputStream() in HttpURLConnection in Android always failed

<pre><code>HttpURLConnection urlConn = (HttpURLConnection) new URL(

InputStream is = urlConn.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(is));

<p>When it comes to urlConn.getInputStream(), it fails.
But the same code works in normal java project instead of Android project.</p>
<p>And I find that in Android, when it runs the first statement, urlConn is:"libcore.net.http.HttpURLConnectionImpl:http://www.google.com"</p>
<p>But in normal java project, it is "sun.net.www.protocol.http.HttpURLConnection:http://www.google.com"</p>

C++::How to put different length arrays of const strings into common class
|
<p>Sorry, new to C++, converting from C, and have struggled to find a good way to do this...</p>
<p>//Fragment follows</p>
<pre><code>const char *List1[]={"Choice1", "Not a good choice", "choice3"}; //rom-able
const char *List2[]={"Hello", "Experts", "Can", "You", "Help?"};
class ListIF{
private:
int index;
char *list;
public:
void GetValString(char *tgt,int len);//get parameter value as string max len chars
void SetIndex(int n){index = n;};
int GetIndex(void){return index;};
};
</code></pre>
<p>//end Fragment</p>
<p>The problem is how to write the constructor so that I can "encapsulate" the lists inside the class, without getting heap bloat (embedded target). And then how to write the gettor so that we can see list[index] within the class.</p>
<p>I am going daft trying to do something that seems obvious, so I am missing something?</p>

Does prototype really matter in JavaScript if the class will never be subclassed?
|
<p>So, in answering another question on this site, I wrote a class for someone to create a BitArray instance in JavaScript. The code I posted looked like this:</p>
<pre><code>var foo = function(param1) {
this._member = param1;
this.getMember = function() { return this._member; };
this.setMember = function(val) { this._member = val; };
this.alertMember = function() { alert(this._member); };
foo.STATIC_CONSTANT = "some value";
}
</code></pre>
<p>One of the comments I received was a rather stern "You should absolutely add the methods to foo.prototype instead of this". If I take that criticism and apply it to the above, it turns the code into:</p>
<pre><code>var foo = function(param1) {
this._member = param1;
}
foo.prototype.getMember = function(){ return this._member; };
foo.prototype.setMember = function(val) { this._member = val; };
foo.prototype.alertMember = function() { alert(this._member); };
foo.STATIC_CONSTANT = "some value";
</code></pre>
<p>My question is, what's the difference here between the two approaches assuming foo will never be subclassed? </p>
<p>To be clear, I'm not advocating writing sloppy code - I credit the commentor with catching me being sloppy - but as I was conceeding to his correctness, it really did make me think - why should I prototype if I'm creating an effectively sealed class? </p>
<p>Is there some performance or functional consequence I'm missing here? Or when a class won't be subclassed is using the prototype irrelevent?</p>

PHP dollar sign in strings
|
<p>I don't unserstand why PHP doesn't make replacements in strings containing dollar signs.
Look at the following example:</p>
<pre><code><?php
error_reporting (E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
$var = 1024;
$str = '$var';
echo $str, '<br>', "$str";
</code></pre>
<p>Output is <em>$var $var</em>. Why is it so? Everything is clear with first <code>echo</code> parameter, but I expected that the last parameter will give a different result (1024), because it contains dollar sign encapsulated by double quotes, so it should be interpreted as variable and replaced to 1024. Where am I going wrong?</p>

Parsing the integer part of string
|
<p>I have a string which could be entered as <code>{n}d {n}h {n}m {n}s</code> where <code>{n}</code> is a integer denoting the number of days, hours, min, sec. How would I extract this <code>{n}</code> number from the string?</p>
<p>The user does not have to enter all 4 - d, h, m, s. He could only enter 4d which means 4 days or 5h 2s which means 5 hours and 2 sec. </p>
<p>Here's what I have. Definitely there should be a better way to do this. Also, does not cover all cases. </p>
<pre><code>int d; int m; int h; int sec;
string [] split = textBox3.Text.Split(new Char [] {' ', ','});
List<string> myCollection = new List<string>();
foreach (string s in split)
{
d = Convert.ToInt32(s.Substring(0,s.Length-1));
h = Convert.ToInt32(split[1].Substring(1));
m = Convert.ToInt32(split[2].Substring(1));
sec = Convert.ToInt32(split[3].Substring(1));
}
dt =new TimeSpan(h,m,s);

Updated to Android sdk r15, but now I can't use anything
|
<p>I'm not sure what I did wrong, but I'll try and give as much information as I can.</p>
<p>Yesterday, I updated a few things in the manager, with one of them being sdk r15. Now, I'm not sure what was updated because I believe there is the sdk 15 and the adt plugin r15. In any case, one of them was updated. I didn't restart and continued to work without any problems. However, today my emulator stopped loading the app I was testing. I restarted eclipse and was thrown this prompt:</p>
<blockquote>
<p>"This Android SDK requires Android Developer Toolkit version 14.0.0
or above. Current version is 12.0.0.v201106281929-138431. Please
update ADT to the latest version."</p>
</blockquote>
<p>Currently, all of my projects have error symbols next to them. I then proceed to click the AVD manager, which I'm given a prompt that says: </p>
<blockquote>
<p>"The location of the Android SDK has not been setup in Preferences."</p>
</blockquote>
<p>I go to Preferences and see that the sdk path is pointing to the correct folder. I haven't changed anything so I dont see how the path could be a problem. </p>
<p>What happened? How can I get things working again? Perhaps, the update did not install everything properly? </p>
<p>EDIT:
By the way, I "apply" and "ok" are greyed out in Preferences no matter which folder I choose.</p>

Passing form name and form object names to functions
|
<p>I'm having trouble understanding the workings of Javascript...I want to pass a form name and the submit button name so that the function can evaluate a passed value and either enable or disable the submit button. </p>
<p>It works if I explicitly use the names but I'd like it to work dynamically. Unfortunately I just am not understanding how to correctly use these arguments.</p>
<p>Right now the first document statement works (form name and button name are used), why doesn't the second, where arguments are used? I know from the alert that the form name isn't correct and can't be used as is but this won't work even if I explicitly name the form but use the passed button name which does appear correct.</p>
<p>I know this must be javascript 101 but I run into this time and again and am just not getting what's what. Anyone willing to explain this to me?</p>
<pre><code><script type="text/javascript">
function aTest(formName,objName,val){
if (val<5){
document.aForm.aBtn.disabled=false;
alert(formName+" - "+objName);
}
else {
document.formName.objName.disabled=true;
}
}//end function aTest(formName,objName)
</script>
<form name="aForm">
<input name="testFld" type="text" onBlur="aTest(this.form,'aBtn',this.value)">
<input name="aBtn" type="submit" value='submit'></form>

inject JS code into a textarea
|
<p>I am trying to show some JS code in a textarea. The code is generated with JS so I am injecting it into the textarea with JS. However, using the <code><script></code> tags, causes the script to execute. I thought using <code>&lt;</code> would solve this, but this is simply displaying <code>&lt;</code> instead of <code><</code>.</p>
<p>Any suggestions how I can do this?</p>

body runat="server" causing compilation error

<p>In a Master Page I have the following markup</p>

<p>However, this is giving my a compile error, with a message of "Cannot resolve symbol someJavaScriptFunction();". If I run the application I get an error telling me</p>
<pre>Compiler Error Message: CS1026: ) expected</pre>
<p>What is going on here? <code>onload</code> is a client-side event, so why does the ASP.NET compiler care about this?</p>

How can a type that is used only in one compilation unit, violate the One Definition Rule?
|
<p>I was told that these types, that are visible in there own unique translation unit, were in violation of the One Definition Rule. Can someone explain this?</p>
<pre><code>//File1.cpp
#include "StdAfx.h"
static struct S { int Value() { return 1; } } s1;
int GetValue1() { return s1.Value(); }
//File2.cpp
#include "StdAfx.h"
static struct S { int Value() { return 2; } } s2;
int GetValue2() { return s2.Value(); }
// main.cpp
#include "stdafx.h"
extern int GetValue1();
extern int GetValue2();
int _tmain(int argc, _TCHAR* argv[])
{
if( GetValue1() != 1 ) throw "ODR violation";
if( GetValue2() != 2 ) throw "ODR violation";
return 0;
}
</code></pre>
<p>I know how to fix the problem. As per the title, I was looking to why it was a ODR violation. How does it violate: "In any translation unit, a template, type, function, or object can have no more than one definition."? Or maybe it violates a different part of the rule.</p>

difference between final int and final static int

<a href="http://stackoverflow.com/questions/2070669/java-is-using-a-final-static-int-1-better-than-just-a-normal-1">java: is using a final static int = 1 better than just a normal 1?</a> </p>

<p>Well I'd like to know what difference between:
final int a=10;
and
final static int a=10;
when they're the member variables of a class, they both hold the same value and cannot be changed anytime during the execution.
Is there any other difference than that the static variable is shared by all the objects and a copy is created in case of non-static variable?</p>

Cast to not explicitly implemented interface?
|
<p>Let's say you define some arbitrary interface:</p>
<pre><code>public interface IInterface
{
void SomeMethod();
}
</code></pre>
<p>And let's say there are some classes that happen to have a matching public interface, even though they do not "implement IInterface". IE:</p>
<pre><code>public class SomeClass
{
public void SomeMethod()
{
// some code
}
}
</code></pre>
<p>is there nevertheless a way to get an IInterface reference to a SomeClass instance? IE:</p>
<pre><code>SomeClass myInstance = new SomeClass();
IInterface myInterfaceReference = (IInterface)myInstance;
</code></pre>

Swapping pointer to pointer
|
<p>In this program I'm writing, I'm using 2 matrices declared as pointer to pointer. Initially, matrix B is equal to matrix A, and all the changes are being made to matrix B (I need to not modify the values in A because I'm using those values to compute something else and if I directly modify it I practically get the wrong result). In the end, I need to swap the values in the two matrices. My program is already running and compiling, but to swap the matrices I've used </p>
<pre><code>for(i=0;i<n;++i)
for(j=0;j<n;++j)
A[i][j]=B[i][j];
</code></pre>
<p>I know that's not the best method, so I was wondering whether there's a way to swap my matrices by pointers. I've already tried to do it myself. but I'm new to C++ programming and I cannot seem to manage to do it right :(. </p>
<p>This is a sketch of my code: </p>
<pre><code>void swap(int **A, int **B){
?
}
main (){
int **A, **B;
*code*
swap(A,B);
}

whats the significance between having the java class containing the main method setup as public and not
|
<p>When I started learning Java I too started with the ubiqutous Hello world app. Which is more or less like :</p>
<pre><code>public class MyClass {
public static void main(String args[]){
//some code here....
}
}
</code></pre>
<p>Its been many years since my tryst with Java but recently I was confronted by a beginner with a problem : Her class file wouldn't run even though she was able to compile correctly.</p>
<p>After looking at her code the first thing I noticed was that is didn't have the public access specifier on the class with the main method. I immediately mocked her on that slip up and went about "fixing" it by adding the public access modifier. The joke was on me offcourse as that didn't make any difference either. I then realized that she was trying to execute the compiled class from a different directory from the one where the class file was. I changed to that dir and issued the java command and it ran immediately. </p>
<p>This brings me to my question... Most hello world examples have the class setup with public access when its just as ok to not have that at all. So what difference does it make if at all for a class that contains the main method ? </p>
<p>To help make it clearer as to what we were doing exactly here are the steps :</p>
<p>We had the class in </p>
<pre><code>c:\users\[usersname]\[my documents folder]\myprog.class
</code></pre>
<p>and we tried to run it from c:\ (as our working dir) . We did specify the full relative path expecting it to work. like so :</p>
<pre><code>java users\[usersname]\[my documents folder]\myprog
</code></pre>
<p>Offcourse this just failed untill I changed into the documents folder making it the current working dir and issuing the command again like so</p>
<pre><code>java myprog
</code></pre>
<p>So basically such a call makes sense when you have the class in a package resembling the folder structure prepended to its name. In this case the class is not in any package.</p>

Make a piece of heap memory read-only
|
<p>If I have a database application in C++. When the data size is small, it's easy to debug for bugs.
But when the data size becomes huge, and relationship becomes complex, the bug is very hard to debug, or hard to find the root cause of it. Sometimes the callstack can't tell you enough information to find the root cause, because the memory has been collapsed. It's very easy the memory of one component is written by other component. Only when the first component visit that memory, we met the crash, but it's too late.</p>
<p>The difficulty to find the root cause is proportional to the size of the handling data.</p>
<p>I am wondering if there is any tricks to predicate the risk, and protection code for avoid illegal memory written.</p>
<p>C++ pointer is a powerful tool, but it's also the high risk to use it. Any code could use the pointer to write/update the memory anytime. When one code write a memory, no other class object know it unless the class visit that memory,then find the value is already invalid, crashed.</p>
<p>If A hold a pointer to B, then some code write that memory to make the value to C.
Then when A use the B pointer to do something, invalid pointer.</p>
<p>I want to know, maybe it's impossible, if there some way to avoid this situation. Could we add some protection code there.</p>
<p>One method I thought could be is I could make the memory to be writable before change, after change make it readable. So other code can't write it, otherwise crash. This would help me to find the issue earlier.</p>
<p>Is there some way to make a piece of heap memory read-only?</p>
<p>Platform is windows. I hope I could use some switch in the code to control it's access right.</p>

header location delay
|
<p>I have the following php code which I want to add a delay too:</p>
<pre><code><?php
echo "Message has been sent.";
header("Location: page2.php", true, 303);
exit;
?>
</code></pre>
<p>The above code happens too fast so I can't see the message:</p>
<p>I have tried:</p>
<pre><code><?php
sleep(5);
echo "Message has been sent.";
header("Location: page2.php", true, 303);
exit;
?>
</code></pre>
<p>This doesn't display the message either, but it does sleep for 5 seconds, which is just a waste of time.</p>
<p>How do I get it to display a message for 5 second before redirecting?</p>

How can I make my function work with my if statement that changes my array
|
<p>In the script below I have an array. My array stores all the links, titles and descriptions from a web page. But I want to make sure that if there is no description, it will use the first 20 characters of a p tag using a function which works. Only problem is I have the jigsaw pieces and just can't seem to put them together, So I want my if statement to show that if the description is empty to use the function getWord instead of <code>getMetas()</code>.</p>
<pre><code>function getMetas($link) {
$str1 = file_get_contents($link);
if (strlen($str1)>0) {
preg_match_all( '/<meta.*?name=("|\')description("|\').*?content=("|\')(.*?)("|\')/i', $str1, $description);
if (count($description) > 1) {
return $description[4];
}
}
}
</code></pre>
<p>Then my function goes here (<code>get_custom_excert</code>), but there is no need to see that as I know that works.</p>
<pre><code>function getWord() {
$html = file_get_contents($link);
preg_match('%(<p[^>]*>.*?</p>)%i', $html, $re);
$res = get_custom_excerpt($re[1]);
}
$outputs = array();
foreach ($links as $thisLink) {
$output[] = array("link" => $thisLink, "title" => Titles($thisLink), "description" => getMetas($thisLink));
if ($output['description'] == null) {
$output['description'] = getWord($res);
}
$outputs[] = $output;
}
print_r($output);
</code></pre>

How to go from a selected button in a list to different activities or the same activity with different text
|
<p>So, I'm making my first android app and want to perform a simple task, but can't seem to figure out the way to do it. I simply want to go from a list view to a screen of differing information based on which button was pressed. The information is similar enough(ie. a title and block of text) that I think I can use the same activity for it all, but I don't know how to switch out the different information based on the user's selection. Should I make a separate activity for each button in the list, or can I have the first activity send context to a single next activity and somehow determine what xml code to use, and how do I do it?</p>

How do I hide a specific value from users in script source?
|
<p>I'm trying to hide a value in the PHP source code to prevent users from seeing the IP of a game server.
The following code shows up in the source code:</p>
<pre><code>"connection.host" : "888.888.888.888",
"connection.port" : "30000",
</code></pre>
<p>So in this case I would like to hide 888.888.888.888 (Which is the IP of a server).
Is there a way to encode this so the user won't see this?
I heared about Ioncube but I'm looking for something else if that is possible.</p>
