Testing if either of two condtions are true

<p>I'm trying to test if either of two variables are true using the code below, but I the code always returns the true conditions even when the variable is blank. Have I done this correctly or is it possible the variables are always true?</p>
<p>Thanks in advance for your help.</p>
<pre><code><?php
if (($gogo_team_member_twitter !== true) or ($gogo_team_member_facebook !== true)) {
echo('class="amb-with-socal"');

How do I access javascript functions in the "object Window"
|
<p>I feel silly asking this in such a crude way, but in Firebug I see my current object (this) and below that a line then, "object Window," where the global namespaces seem to live (e.g., there's a <code>$</code> object, <code>jQuery</code> object ...). I have an object I created called "g" with a function called "Update" that lives in this global namespace (again, using that term loosely).</p>
<p>Am I using the right terminology here? Does the jQuery object live in the "global namespace"? Furthermore, if I want to call something living here, do I just need to call, say, <code>g.Update()</code>? Would it be right to say these are the equivalent of what you'd call static variables in OO terminology?</p>
<p>Thanks!</p>

Where would I use a bitwise operator in JavaScript?
|
<p>I've read <strong><a href="http://stackoverflow.com/questions/276706/what-are-bitwise-operators">this</a></strong> (<a href="http://stackoverflow.com/questions/276706/what-are-bitwise-operators">http://stackoverflow.com/quest...</a>), so I know <strong>what</strong> bitwise operators are but I'm still not clear on how one might use them... Can anyone offer any real-world examples of where a bitwise operator would be useful in JavaScript?</p>
<p>Thanks.</p>
<h2>Edit:</h2>
<p>Just digging into the <strong><a href="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js">jQuery source</a></strong> I've found a couple of places where bitwise operators are used, for example: (only the & operator)</p>
<pre><code>// Line 2756:
event.which = (event.button & 1 ? 1 : ( event.button & 2 ? 3 : ( event.button & 4 ? 2 : 0 ) ));

Moving inline code into function, with object name generation
|
<p>I am customizing Denis Gritcyuk's <a href="http://javascriptkit.com/script/script2/timestamp.shtml" rel="nofollow">Popup date picker</a>.</p>
<ol>
<li><p>This pop-up script uses inline Javascript in a <code>href</code> link, to set the selected date into the <code>input</code> field, in the parent window, that is was called for. An example URL looks like:</p>
<pre><code><a href="javascript:window.opener.document.formname.field.value='03-10-2011';
window.close();">3</a>
</code></pre></li>
<li><p>The input field name, (e.g. <code>document.formname.field</code>), is passed to the script as a string parameter.</p></li>
</ol>
<p>I would like to add things done when that link is clicked (e.g. change background color of field, set flag, etc.). So while this DOES work, it's getting <strong>ugly</strong> fast.</p>
<pre><code><a href="javascript:window.opener.document.formname.field.value='03-10-2011';
window.opener.document.formname.field.style.backgroundColor='#FFB6C1';
window.close();">3</a>
</code></pre>
<p><br>
How would I move these inline commands into a JS function? This would give me much cleaner URLs and code. The URL would now look something like </p>
<pre><code><a href="javascript:updateField ('document.formname.field', '03-10-2011');">3</a>
</code></pre>
<p>with a function like (this example obviously does NOT work):</p>
<pre><code>function updateField (str_target, str_datetime) {
var fieldName = "window.opener" + str_target;
[fieldName].value = str_datetime;
[fieldName].style.backgroundColor = '#FFB6C1';
// Set flag, etc.
window.close();
}
</code></pre>
<p><br>So any suggestions on how this can be done, please?</p>

Javascript understanding

<p>This is probably a stupidly basic question for this community, but if someone could explain it to me I would be very great full, I am so confused by it. I found this tutorial on the net and this was example.</p>
<pre><code><script type="text/javascript">
function sports (x){
alert("I love " + x);
}
sports ("Football");
sports ("Rally");
sports ("Rugby");
</script>
</code></pre>
<p>Why does this display the 3 variables: Football, Rally and Rugby?</p>
<p>Is it because x = sports? So when the variables of sports are defined they get displayed? </p>
<p>I think I confused myself more when writing this so I hope it kind of makes sense :(</p>

How to access javascript array values within a setinterval function

<p>EDIT: The correct way to do it is self.series[0].data[self.series[0].data.length-1].x to access the last x value</p>
<p>How can I access the series data from within the function defined in setinterval. When I try to access any of the values, or even the array length, it says undefined.</p>
<pre><code>events: {
load: function() {
// set up the updating of the chart each second
var series0 = this.series[0];
var series1 = this.series[1];
var series2 = this.series[2];
var series3 = this.series[3];
setInterval(function() {
var y = $.ajax({url: "/index.php/control/fetch/<?php echo $uid; ?>",async: false}).responseText;
y = y.split(" ");
var x = parseInt(y[0]);
//alert("x = " + series0[0]);
//alert("len is " + parseInt(series0.length));
series0.addPoint([x, parseFloat(y[1])], true, true);
series1.addPoint([x, parseFloat(y[2])], true, true);
series2.addPoint([x, parseFloat(y[3])], true, true);
series3.addPoint([x, parseFloat(y[4])], true, true);

Reloading tab activity onResume but don't want to reload on tab switch
|
<p>I'm not sure if my title is clear so let me explain.</p>
<p>Tab A - contains a listview populated from a database
Tab B - search form</p>
<p>I need to update the contents of tab A after coming back from a search results screen. Using onResume() works great but this also reloads the Tab whenever I click back and forth through between tabs. Is there another method I could use here?</p>
<p>EDIT: I guess it's a bit more complex than this. The search form loads a new intent that displays the results in a listview. An item can be select which then loads a item info screen. From here the user can select from a few option, one being Add. This is the action that needs to reload the original listview in Tab A.</p>

Multidimensional Array to String

foreach($array as $value) {
if(count($value) > 1) {
$array = implode("~", $value);
}
$array = implode("&", $value);
}
print_r($array);
}
$arr = array(array("blue", "red", "green"), array("one", "three", "twenty"));
convert_multi_array($arr);
</code></pre>
<p>Should Output: <code>blue~red~green&one~three~twenty</code> ... and so on for more sub-arrays.</p>
<p>Let me just say that I have not been able to produce any code that is remotely close to the results I want. After two hours, this is pretty much the best I can get. I don't know why the implodes are acting differently than they usually do for strings or maybe I'm just not looking at this right. Are you able to use implode for arrays values?</p>

PHP: Most efficient way to get the number of files within a directory

<p>Consider these two folder structures:</p>
<pre><code>Foo/
Folder1/
File1.txt
Folder2/
Folder3/
File2.txt
Bar/
Folder1/
Folder2/
Folder3/
Folder4/
</code></pre>
<p>I'd like to know the most efficient way in PHP to tell me that the "Foo" folder has two files in it and that the "Bar" folder has zero files in it. Notice that it's recursive. Even though the "File1.txt" file is not <em>immediately</em> inside the "Foo" folder, I still want it to count. Also, I don't care what the names of the files are. I just want the total number of files.</p>
<p>Any help would be appreciated. Thanks!</p>

Opening a file without extension

Javascript, escape is not a function - from firefox?
|
<p>I'm quite puzzled by this one, getting this error from firefox.</p>
<pre><code>escape is not a function
</code></pre>
<p><img src="http://i.stack.imgur.com/EOknY.png" alt="enter image description here">
Looking at the W3C page, it says it is supported as I thought.</p>
<p>I tried <code>escapeURI</code> instead and this produced the same error.</p>
<p>Any suggestions ?</p>

Saving boolean return value into variable?
|
<p>Is there a way to save a boolean true/false value in a function to a variable?</p>
<pre><code>function check() {
if(1 = 1) {
return false;
}
}
$status = check();
if($status === false) {
echo "sign in please";
}
</code></pre>
<p>As of now <code>$status</code> comes out to be null. I don't like having to use <code>if(check() === false) {}</code> since a lot of my function have a lot of arguments. And setting <code>$status</code> within the function would defeat the purpose of a universal function that can be used for multiple variables.</p>
<p>How do you guys handle this?</p>
<p>EDIT: I apologize, something else in my code was causing it to be null. Tried to make a test (above code) and when it failed, I thought it was a worthy question :P</p>

C++ question about setting class variables
|
<p>I'm not new to programming, but after working in Java I'm coming back to C++ and am a little confused about class variables that aren't pointers. Given the following code:</p>
<pre><code>#include <iostream>
#include <map>
using namespace std;
class Foo {
public:
Foo() {
bars[0] = new Bar;
bars[0]->id = 5;
}
~Foo() { }
struct Bar {
int id;
};
void set_bars(map<int,Bar*>& b) {
bars = b;
}
void hello() {
cout << bars[0]->id << endl;
}
protected:
map<int,Bar*> bars;
};
int main() {
Foo foo;
foo.hello();
map<int,Foo::Bar*> testbars;
testbars[0] = new Foo::Bar;
testbars[0]->id = 10;
foo.set_bars(testbars);
foo.hello();
return(0);
}
</code></pre>
<p>I get the expected output of 5 & 10. However, my lack of understanding about references and pointers and such in C++ make me wonder if this will actually work in the wild, or if once testbars goes out of scope it will barf. Of course, here, testbars will not go out of scope before the program ends, but what if it were created in another class function as a function variable? Anyway, I guess my main question is would it better/safer for me to create the bars class variable as a pointer to the map map?</p>

Building a .net 1.1 project using msbuild
|
<p>The Web project we are working on is built against .net 1.1 framework.We would like to automate the build process for this project by using msbuild.However MSBuild only targets 2.0 framework. So how can this be done if we like to use MSBuild or MSBEE(this asks us to convert the web project to new version by opening up in Visual studio IDE)?We cannot convert the project to suit to 2.0 framework</p>

How do you explicitly initialize a reference in c++?
|
<p>I have the following code:</p>
<pre><code>class SomeClass {};
class SomeOtherClass {
SomeClass& someObj;
public:
SomeOtherClass() {someObj = SomeClass();}
};
</code></pre>
<p>And I get an error on the constructor for <code>SomeOtherClass</code> saying <code>Constructor for 'SomeOtherClass' must explicitly initialize the reference member 'someObj'</code>.</p>
<p>So I guess my question is pretty strait forward. How do you initialize a reference?</p>

Remove non printable characters C# multilanguage
|
<p>I have a multi-language application in asp.net C#. Here I have to create a zip file and use some items from the database to construct file name. I strip out special characters from file name. However if the language is German for example my trimming algorithm will remove some german characters like Umlaut.</p>
<p>Could someone provide me with a language adaptable trimming algorithm.</p>
<p>Here is my code:</p>
<pre><code>private string RemoveSpecialCharacters(string str)
{
return str;
StringBuilder sb = new StringBuilder();
foreach (char c in str)
{
if ((c >= '0' && c <= '9') || (c >= 'A' && c <= 'Z') || (c >= 'a' && c <= 'z') | c == '.' || c == '_' || c == ' ' || c == '+')
{
sb.Append(c);
}
}
return sb.ToString();
}

is it possible to write an app that is invoked by the phone ringing?
|
<p>I'm guessing the answer is no, but just in case, I'm curious if there's any way to write a receiver that would launch an app when the phone starts to receive a call. Even something as simple as a dialog activity that says "your phone is ringing". Or is the phone always going to suppress any other app that's trying to run?</p>

Java object error
|
<p>Ok I'm very new to Java and I'm trying to complete a homework assignment, but my object isn't working in my class. (Forgive me if I'm using wrong terminology, noobie here)</p>
<p>So I'm making a basic stopwatch program that records 2 laps. I have gotten to the point of creating the 1st lap and it works great. Then when I call the timer.reset() object to reset the stopwatch it displays the same time as the first lap. Why isn't my timer.reset() not working?</p>
<pre><code>public class StopWatch
{
/**
* This method
*
* @param args
*/
public static void main(String[] args)
{
// TODO Auto-generated method stub
Scanner input = new Scanner(System.in);
System.out.println("Start stopwatch [press s]: ");
System.out.println("Stop stopwatch [press q]: ");
Timer timer = new Timer();
input.next();
timer.start();
input.next();
timer.stop();
int elapsedTime = timer.getElapsedTime();
System.out.print("Elapsed time: ");
System.out.print(elapsedTime);
System.out.println(" milliseconds");
timer.reset();
input.next();
timer.start();
input.next();
timer.stop();
System.out.print("Elapsed time: ");
System.out.print(elapsedTime);
System.out.println(" milliseconds");
}
}
</code></pre>
<p>Here's the timer.java class im using in my program.</p>
<pre><code>public class Timer {
private long start;
private long stop;
private int elapsedTime;
public Timer() {
}
public void start() {
if (this.start == 0 && this.stop == 0)
this.start = System.currentTimeMillis();
}
public void stop() {
if (this.start > 0 && this.stop == 0) {
this.stop = System.currentTimeMillis();
this.elapsedTime = (int) (stop - start);
}
}
public int getElapsedTime() {
return this.elapsedTime;
}
public void reset() {
this.start = 0;
this.stop = 0;
this.elapsedTime = 0;

onLocationChanged not getting called other than the first time for GPS
|
<p>I am using GPS on Android phone, and trying to get GPS coordinates from satellite. I have disabled wifi on my phone.</p>
<p>I am using the following code snippet,</p>
<pre><code>mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, (float)0.0, mlocListener);
</code></pre>
<p>the <code>onLocationChanged</code> function will get called everytime as I have set my <code>minTime</code> and <code>minDistance</code> as <code>0</code>.(i am able to see this on the phone)</p>
<p>However I want GPS coordinates to be updated only when I change my distance by 1m.
Thus I use,</p>
<pre><code>mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, (float)1.0, mlocListener);
</code></pre>
<p>Now the <code>onLocationChanged</code> function is getting called only for the first time when application starts, however if I move my even more than 10metres the <code>onLocationChanged</code> does not get called.</p>
<p>The function prototype is ,</p>
<pre><code>public void requestLocationUpdates (String provider, long minTime, float minDistance, LocationListener listener)
</code></pre>
<p>Can someone please tell me a solution.</p>
<p>Thanks</p>

Why doesn't my PHP foreach work?
|
<pre><code>$start = true;
$new = "";
foreach($array as $val)
{
if($start = true && $val != " ")
{
$start = false;
$new .= strtoupper($val);
}
elseif($val == " ")
{
$new .= " ";
$start = true;
}
else
{
$new .= strtolower($val);
}
$start = false;
}
</code></pre>
<p>Basically what happens is <code>$start</code> NEVER becomes <code>false</code> AND everything becomes capitalized. So it looks like the first <code>if</code> IS running, but for some reason NEVER SETS <code>$start</code> to <code>false</code>. </p>

Drag and drop javascript event

How to extend a Java class with a loaded class?
|
<p>I am injecting a Applet that way that it can't check on which website it is.<br />
The purpose is to load an external unmodified applet into mine so I can embed it into mine.</p>
<pre><code> final URL[] appletURL = { new URL(Main.getBase() + "/loader.jar") };
final URLClassLoader classLoader = new URLClassLoader(appletURL); // gets the class
final Class<?> loader = classLoader.loadClass("loader"); // loads the class
applet = (Applet) loader.newInstance(); // creates the applet
applet.setStub(new Injector()); // injects the getdocumentbase, so it thinks he is on his own website
applet.init(); // start applet
applet.start();
applet.setPreferredSize(new Dimension(800, 600)); // to be able to add to jframe properly
</code></pre>
<p>The "applet.setStub(new Injector());" part is to prevent navigating away or not loading because it's not the applet's own website.<br />
But now I want to render the external applet to a screenshot.
I tried this:</p>
<pre><code>@Override
public void actionPerformed(final ActionEvent e) {
final String s = e.getActionCommand();
if (s.equals("Screenshot")) {
final BufferedImage offScreen = new BufferedImage(800, 600, BufferedImage.TYPE_INT_RGB);
applet.update(offScreen.createGraphics());
try {
ImageIO.write(offScreen, "PNG", new File("C:/Users/Mitchell/Pictures/screenshot.png"));
} catch (Exception ex) { }
}
}

<p>But it doesn't use the paint nor updat method.
It uses getGraphics() instead, I got tipped to extend the applet that I want to screenshot.
But the applet is dynamically loaded, so how do I extend a class with a loaded class (or applet)?</p>
<p>Can someone provide a code sample?
I am about to freak out because this is taking all my time and I can't continue without this.</p>

Check if a “run-time” multidimensional array key exists

</blockquote>
<p>Hi,</p>
<p>I have a multidimensional array. I need a function that checks if a specified key exists and if not set the value.</p>
<p>Let's take this array</p>
<pre><code>$config['lib']['template']['engine'] = false;
</code></pre>
<p>A function should not update the value to true when i call with:</p>
<pre><code>checkAndSetKey('lib template engine',true);
//> Checks if isset $config['lib']['template']['engine'] and if not isset $config['lib']['template']['engine'] = true;
</code></pre>
<p>Note that my array isn't only 3 dimensional. It should be able to check and set even with only 1 dimension:</p>
<pre><code>checkAndSetKey('genericSetting',true);
//> In this considering there isn't any $c['genericSetting'] the function set the key to true;
</code></pre>
<p>At the moment I am using an awful eval code, I would like to hear suggest :)</p>
<p>To dynamically check if the key exists it could be used this code:</p>
<pre><code>$array = $config;
$keys=explode(' ',$argument1);
foreach($keys as $v) {
if (!array_key_exists($v,$array)) {
//> [todo!] the current key doens't exist now we should set the value
}
$array = &$array[$v];
}
</code></pre>

How can i get a value from a string with an alternating name?
|
<p>I have the following code:</p>
<pre><code>var currentCity = db.City.Find(player.Location);
switch (TravelTo) {
case 1:
costs = currentCity.TravelCost.City1;
break;
case 2:
costs = currentCity.TravelCost.City2;
break;
case 3:
costs = currentCity.TravelCost.City3;
break;
case 4:
costs = currentCity.TravelCost.City4;
break;
case 5:
costs = currentCity.TravelCost.City5;
break;
}
</code></pre>
<p>Is there a better way to get the cost value? Is there a way i can change the name of the string i want to call? So i could create something like</p>
<pre><code>costs = currentCity.TravelCost.City[TravelTo]
</code></pre>
<p>Or something like that? I feel i wrote an unnecessary switch statement but my knowledge of C# is not good enough to come up with an alternative.</p>

How to read compressed HTML page with Content-Encoding : gzip
|
<p>I request a web page that sends a <strong>Content-Encoding: gzip</strong> header, but got stuck how to read it..</p>
<p>My code:</p>
<pre><code> try {
URLConnection connection = new URL("http://jquery.org").openConnection();
String html = "";
BufferedReader in = null;
connection.setReadTimeout(10000);
in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null){
html+=inputLine+"\n";

Is there a way to express a generic handler in a generic way in C#?
|
<p>Imagine I have an interface that specifies some collection handler:</p>
<pre><code>interface ICollectionHandler<T> where T : new() { ... }
</code></pre>
<p>I then have same other class that wants a collection handler, which it will use for various types, so I want to do something like:</p>
<pre><code>class SomeClass<T> where T : ICollectionHandler<> ...
</code></pre>
<p>If I do this though, I get an error saying that the "Type argument is missing".</p>
<p>So is there a way of specifying that T is a generic type, whose own type argument can be specified at runtime, or am I pushing C# beyond its (possibly sensible) boundaries here?</p>

Time delay in Javascript

<p>Function PS.Tick() is called every 100 milliseconds and its job is to call AI function of NPCs so they can move:</p>
<pre><code>PS.Tick = function ()

for (NPCid = 0; NPCid < NPCnumber; NPCid++)
{
NPCAI(NPCid);
};
};
</code></pre>
<p>But I want the NPCs to not move simultaneously every 100 millisecond, but do it at their own frequency, so I tried this code:</p>
<pre><code>PS.Tick = function ()
{
"use strict";
for (NPCid = 0; NPCid < NPCnumber; NPCid++)
{
var timeout = 0;
timeout = PS.Random (1000);
setTimeout("NPCAI(NPCid)",timeout);
};
};

<p>Now, they don't move at all. Why? How do I make them move at different time intervals?</p>

Python tool to balance parentheses, quotes, and brackets

<p>Does anyone know of an already-written Python script, tool, or editor that will check for unbalanced multi-line tokens? (parentheses, quotes, {}, [], etc.)</p>
<p>I've been writing Python code in IDLE, and every so often I'll get "EOF token in multi-line statement" and start swearing, because it means that somewhere in about 200 lines of code I forgot a closing parenthesis or quote and IDLE can't tell me where. This seems like a fairly straightforward thing, I just don't really have the time or headspace to work it out myself right now.</p>

Best way to procedurally add Power-up items to an iPhone game
|
<p>To better explain this I'll use Doodle Jump as an example. Assuming that the platforms are recycled, when the character jumps up and the new platforms appear (by scrolling down) there is occasionally a propeller hat on one of them. is there a recommended method to manage this new object? Should I instantiate a single one of these power-ups in the game level's "init" method, and then set a boolean to flag whether it appears in my render method and update methods? Or should I instantiate it at the time that I want it to appear (i.e. just before the new platform scrolls down from its position just above the screen) and release it when it's a) grabbed by the character sprite or b) moves off the screen untouched?</p>
<p>Thanks!</p>

Passing a bound object method in JavaScript
|
<p>For a Firefox extension, I'm trying to do the following:</p>
<ol>
<li>Setup an object with two methods and a field/property/attribute</li>
<li>One of the methods has to be able to call the other method and access the attribute</li>
<li>I want to register that method as an event listener.</li>
</ol>
<p>Right now, I have it setup like a class:</p>
<pre><code>var Obj = {
field: null,
a: function() { }
b: function() {
Obj.field = 'x';
Obj.a();
}
}
window.addEventListener('mouseup', Obj.b, false);
</code></pre>
<p>But it seems like it should be possible to have the mod not refer to the object "from the outside" (e.g. by using <code>Obj</code>), but using just <code>this</code> instead. However, I can't figure out how to get this to work correctly, pass a simple function reference to <code>addEventListener()</code> <em>and</em> (preferably) only polluting the namespace with a single name. Is that possible? I tried googling for it and found e.g. <a href="http://ejohn.org/blog/simple-class-instantiation/" rel="nofollow">http://ejohn.org/blog/simple-class-instantiation/</a>, but that didn't seem to lead to something that fits my criteria of a clean setup.</p>

Why use generic constraints in C#

}
</code></pre>
<p>can't I switch ALL references of <code>T</code> in this class with <code>ISomething</code>?</p>
