parse_str appending ampersand to elements?
|
<p>I've been playing around with cURL, and am trying to send an array through as POST variables. I've decided to use http_build_query to pass the string as expected: </p>
<pre><code>curl_setopt($this->ch, CURLOPT_POSTFIELDS, http_build_query($sendParams));
</code></pre>
<p>I have the receiving end simply <code>print_r</code>'ing the $_POST, so I can see what is being sent through.</p>
<p>However, I am getting an ampersand attached to all of the parent elements <em>after</em> the first, is this normal? I assume that parse_str is used by cURL when parsing the querystring, so here is a super-simplified example that also leads to the ampersands:</p>
<pre><code><?php
$array = array('foo', array('bar' => array('baz' => array(1,2,3))), 'test' => array(2,3,4));
parse_str(http_build_query($array), $vars);
print_r($vars);
?>
</code></pre>
<p>Returns:</p>
<pre><code>Array ( [0] => foo [amp;1] => Array ( [bar] => Array ( [baz] => Array ( [0] => 1 [1] => 2 [2] => 3 ) ) ) [amp;test] => Array ( [0] => 2 [1] => 3 [2] => 4 ) )
</code></pre>

Missing section declaration (system.web.extensions)
|
<p>I am encountering an issue wherein when I added the system.web.extensions on my web.config, I am getting the error saying, "Missing section declaration(system.web.extensions)".</p>
<p>The main root of this issue comes from another issue, which says "System.InvalidOPerationException: Error during serialization or deserialization using the JSON JavaScriptSerializer.", so when I researched for answers, they said that you need to add this configuration on your web.config,</p>
<pre><code><system.web.extensions>
<scripting>
<webServices>
<jsonSerialization maxJsonLength="500000">
</jsonSerialization>
</webServices>
</scripting>
</system.web.extensions>
</code></pre>
<p>But when I add this code, I am getting the "missing declaration issue", question is, what file/s do I need to modify so that the system.web.extensions can be read by my web.config? I am getting stuck here.</p>
<p>@edit: My web application is running on a V2.0, is this achievable using this version?</p>
<p>Thanks.</p>

Equivalent is_file() function for URLs?

<p>What is the best way to check if a given url points to a valid file (i.e. not return a 404/301/etc.)? I've got a script that will load certain .js files on a page, but I need a way to verify each URL it receives points to a valid file.</p>
<p>I'm still poking around the PHP manual to see which file functions (if any) will actually work with remote URLs. I'll edit my post as I find more details, but if anyone has already been down this path feel free to chime in.</p>

Which is better loading of images for ListView?

<p>I am wondering if which of the two is better in loading images in a listview from web, is it by batch through some number of threads that are running simultaneously or one by one through thread queue?</p>
<p>I have noticed (but I don't know if that is really the implementation) from the youtube app that the images are loaded by batch and it is kinda fast. Even for not only loading images but also requesting some data from the web as well. Does anyone have an idea?</p>

Module API mismatch between PHP and SSH2 module
|
<p>I'm trying to install the ssh2 extension for PHP, and after hours of working on it, I've near figured it out. I think.</p>
<p>It's compiled and the ssh2.so is in the correct directory and all. The problem, I believe, is version mismatches.</p>
<p>Here's the error it's spouting for me:</p>
<pre><code>PHP Warning: PHP Startup: ssh2: Unable to initialize module
Module compiled with module API=20050922, debug=0, thread-safety=0
PHP compiled with module API=20060613, debug=0, thread-safety=0
These options need to match
in Unknown on line 0

How to force a method to be overridden in java?
|
<p>newbie question.. I have to create a lot of very similar classes which have just one method different between them. So I figured creating abstract class would be a good way to achieve this. But the method I want to override (say, method foo()) has no default behavior. I don't want to keep any default implementation, forcing all extending classes to implement this method. How do I do this?</p>

jQuery -> Selected Element to HTML

$(document).ready(function() {
$('img').each(function() {
var img = $(this).clone();
var html = '<div class="bounding">'+$(img)+'</div>';
$(this).replaceWith(html);
});
});
</script>
</code></pre>
<p>The script is printing out <code>[object Object]</code>. <code>.html()</code> doesn't work because that is basically innerHTML. Is there a jQuery function that achieves this?</p>

Best way to select n elements at a time in jQuery
|
<p>I have an <code>ul</code> of <code>li</code> elements, what I want to do is this:</p>
<ol>
<li>If there are 6 or less <code>li</code> elements, select them all and put them into a new <code>ul</code>.</li>
<li>For any number greater than 6 elements, loop through, selecting 6 elements, put into new <code>ul</code>, start at the next <code>li</code> element and continue.</li>
<li>If there are less than 6 element left at the end, they get put into a new <code>ul</code> as well.</li>
</ol>
<p>If I start out with 5 <code>li</code> elements, I would hope to end up with 1 <code>ul</code> element with 5 <code>li</code> children.</p>
<p>If I start out with 40 <code>li</code> elements, I would hope to end up with 7 <code>ul</code> elements, 6 with 6 <code>li</code> children and 1 with 4.</p>
<p>What would be the most efficient way of handling this in jQuery?</p>

circularly linked list in python
|
<p>I am stuck implementing the add function of a circularly linked list in python. I have a head pointer that should be a reference to a node, but every time I add something to the list, head is always None. Here is the code I have so far:</p>
<pre><code>class CircleList():
__slots__ = ('head', 'size')
def __init__(self):
self.head = None
self.size = 0
def __str__(self):
result = "<"
node = self.head
count = self.size
while count != 0:
result = result + str(node.data)
if count != 1:
result = result + ", "
node = node.next
count -= 1
result = result + ">"
return result
def add(self, element):
head = self.head
print(head)
size = self.size
if head == None:
head = Node(element, None)
head.next = head
else:
cursor = head
while cursor.next != head:
cursor = cursor.next
temp = Node(element, head)
cursor.next = temp
size += 1
class Node():
__slots__ = ('data','next')
def __init__(self, data, next):
self.data = data
self.next = next
</code></pre>
<p>Here is the driver:</p>

circlelist = CircleList()
for name in stream
circlelist.add(name)
print(circlelist)

How do I append a page's URL to a social media 'sharing' URL in jQuery?
|
<p>How do I create a link that takes the static part of a 'sharing' link (of a social media site like LinkedIn) and appends the url of the current page? So that a user can share the page's URL on their social media account.</p>
<p>I do not want to use Share This or any other such widgets.</p>
<p>Thanks</p>
<p><strong>EDIT</strong></p>
<p>So of the solutions suggested I opted for the jQuery one. After a lot of help, this was the solution:</p>
<p>HTML</p>
<pre><code><a class="linkedin" href="#">LinkedIn</a>
</code></pre>
<p>jQuery</p>
<pre><code>$(document).ready(function() {
$('a.linkedin').click(function() {
var link = document.location;
var url = "https://www.linkedin.com/shareArticle?mini=true&url=" + link;
document.location.href = url;
});
});
</code></pre>
<p>Obviously, it can work for any social media site that allows such URLs.</p>

The field that I set on an global array does not persist
|
<p>On my PHP web-page I have a global array:</p>
<pre><code>$test = array();
</code></pre>
<p>Then I invoke this function:</p>
<pre><code>function f ()
{
global $test;
init( $test );
$test['foo'] // Error: undefined index "foo"
}
</code></pre>
<p>which in turn invokes this function:</p>
<pre><code>function init ( $test )
{
$test['foo'] = 'bar';
$test['foo'] // evaluates to'bar'
}
</code></pre>
<p>As you can see, I get an error. The "foo" field that I've added to the array inside <code>init()</code> did not persist. Why does this happen? I thought I was mutating the global <code>$test</code> inside <code>init()</code>, but it seems that I'm not doing that. What's going on here, and how can I set a "foo" field inside <code>init()</code> that persists?</p>

How to build a single python file from multiple scripts
|
<p>I have a simple python script, which imports various other modules I've written (and so on). Due to my environment, my PYTHONPATH is quite long. I'm also using Python 2.4.</p>
<p>What I need to do is somehow package up my script and all the dependencies that aren't part of the standard python, so that I can email a single file to another system where I want to execute it. I know the target version of python is the same, but it's on linux where I'm on Windows. Otherwise I'd just use py2exe.</p>
<p>Ideally I'd like to send a .py file that somehow embeds all the required modules, but I'd settle for automatically building a zip I can just unzip, with the required modules all in a single directory.</p>
<p>I've had a look at various packaging solutions, but I can't seem to find a suitable way of doing this. Have I missed something?</p>
<p>[edit] I appear to be quite unclear in what I'm after. I'm basically looking for something like py2exe that will produce a single file (or 2 files) from a given python script, automatically including all the imported modules.</p>
<p>For example, if I have the following two files:</p>
<pre><code>[\foo\module.py]
def example():
print "Hello"
[\bar\program.py]
import module
module.example()
</code></pre>
<p>And I run:</p>
<pre><code>cd \bar
set PYTHONPATH=\foo
program.py

What does delete[] do if given a pointer to the middle of an array?
|
<p>What would happen in the following code?</p>
<pre><code> int *p1 = new int[100];
int *p2 = &p1[50];
delete [] p2;
</code></pre>
<p>I've heard that some implementations of new store the size of the array in the (-1)th array index, but then wouldn't things go horribly wrong in the above?</p>

Declaring 'long' over 'int' in Java

Can't remove intent extra!
|
<p>I'm creating a notification for the notification tray. I'm specifying a click intent like this:</p>
<pre><code>Intent intent = new Intent(context, MyActivity.class);
intent.putExtra("foo", true);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
intent.setData(Uri.parse("" + System.currentTimeMillis()));
</code></pre>
<p>The MyActivity class gets launched just fine with the "foo" parameter present. However, I cannot get rid of that extra afterwards - it seems to persist in the Intent:</p>
<pre><code>// MyActivity
public void onNewIntent(Intent intent) {
super.onNewIntent(intent);
// please go away..
intent.removeExtra("foo");
getIntent().removeExtra("foo");
}
</code></pre>
<p>Iterating over the keys of the intent shows that "foo" no longer exists. But if I background the activity, then bring it to the foreground again, the "foo" parameter is present again.</p>
<p>Anyone know how to really get rid of it? I've also tried calling setIntent(), same behavior. It's like the launcher holds onto the original intent and keeps reusing it.</p>
<p>Thanks</p>

Java, declare variable with multiple interfaces?
|
<p>In Java, is it possible to declare a field/variable whose type is multiple interfaces? For example, I need to declare a <code>Map</code> that is also <code>Serializable</code>. I want to make sure the variable references a serializable map. The <code>Map</code> interface does not extend <code>Serializable</code>, but most of <code>Map</code>'s implementations are <code>Serializable</code>.</p>
<p>I'm pretty sure the answer is no.</p>
<p><strong>Follow up</strong>: I'm fully aware of creating a new interface that extends both <code>Map</code> and <code>Serializable</code>. This will not work as existing implementations (such as <code>HashMap</code>) do not implement my new interface.</p>

os.walk and read file, having some problems with walking the path
|
<p>Here is the entirety of my code, I am trying to debug it, but it seems like I can't do any reading of files while using os.walk. The problem is that without changing directories, I am hit with a error that 'out.csv' cannot be found, so i put in a chdir(), to move to that directory to read that file, but now it will only read that one file. My estimate is there should be over 300+ of these files. So it seems to stop after just the first file read after I put in the chdir().</p>
<pre><code>#! /usr/bin/env python
import csv, os
current = os.curdir
filescntd = 0
avg = 0
for root, dirs, files in os.walk('ARCIVE'):
for file in files:
base, ext = os.path.splitext(file)
if ('csv' in ext):
os.chdir(root)
print root
f = csv.reader(open('out.csv','rb'))
count = 0
for row in f:
if (count >= 6 and count <= 10):
tempavg = 0
for i in row:
tempavg += float(i)
filescntd += 1
tempavg /= len(row)
avg += tempavg
count += 1
os.chdir(current)
os.chdir(current)
print '---'
avg /= 5.0
print avg
</code></pre>
<p>output:</p>
<pre><code>ARCIVE/8-15-11/temp/29033
---
0.02775
</code></pre>
<p>the option of filescntd is a little misleading, it is the amount of numbers averaged, and it comes to 40.</p>
<p>To clarify, what I want this program to do, is walk this directory tree and open all files that contain 'csv' in the extension, and read lines 6-10, and average those lines. I am having problems with the walking the path and opening the files.</p>

How to retrieve data from an object in a simple way?

<p>I have an object, which contains 2 name parameters - see the example below. I understand that to reach the data I need to loop through the object, but I feel this is too annoying. Is there a better way to get the data in simple way?</p>
<pre><code>var obj = {[[[{name:'one'},{name:'two'}]]]};
$.each(obj,function(i,val){
var first = [] // i will get first time
$.each(first, function(i, val){
var second = [] //i will get second time and third later fourth // like so?
})
})
</code></pre>
<p>Does this mean that I should loop the <code>each</code> function four times to get the <code>name</code> values? If so which is the right way to get that? Is there any way to use the same function to get the data?</p>

I need some help concerning using 2 jar files in Java
|
<p>Well I have 2 .jar files. The main jar file is the jar file for my whole project and the other .jar file being the MySql JDBC Connector.</p>
<p>Well basically whats happening right now is that when I build the project I have the one main .jar file with everything but the MySql JDBC Connector .jar file is inside the main jar file when it builds in NetBeans.</p>
<p>Now when I am just running the project from within NetBeans the MySql JDBC driver can be found inside the src/com/game/mysql folder that I have it in. But when I build the project the Java application cannot locate the JDBC driver from within the main jar file.</p>
<p>When I open the main jar file with WinRar I can see that the JDBC jar file is still in its /com/game/mysql/ folder. But why cant the Java application access it?</p>
<p>I have heard that nested .jar files are not supported in Java so Im thinking this might be the reason although Im not sure if thats true. Is there a way that I can make it so that the application can find the JDBC .jar file within the main jar file?</p>
<p>Also I have done the thing in NetBeans where you add the .jar file through right clicking project -> properties -> Library -> Add Folder/Jar. Thats what makes it work in the NetBeans run but still not the App build.</p>

No overload for 'pnlArr_Click' matches delegate 'System.EventHandler'
|
<p>Just starting out on C# and I keep getting stuck on this particular piece code (more precisely the <code>lblArr[i, j].Click += pnlArr_Click;</code> line):</p>
<pre><code>public void CreateLabelArray(int height, int width, int nrofShips)
{
pnlBase.Controls.Clear();
lblArr = new Label[height, width];
int xpos = 0;
int ypos = 0;
for (int j = 0; j < width; j++)
{
int column = j + 1;
for (int i = 0; i < height; i++)
{
Coordinaat pos = new Coordinaat();
pos.X = j;
pos.Y = i;
lblArr[i, j] = new Label();
lblArr[i, j].Left = xpos;
lblArr[i, j].Top = ypos;
lblArr[i, j].Width = 35;
lblArr[i, j].Height = 35;
lblArr[i, j].Tag = pos;
lblArr[i, j].Click += pnlArr_Click;
lblArr[i, j].BackColor = System.Drawing.Color.LightBlue;
lblArr[i, j].BorderStyle = BorderStyle.FixedSingle;
pnlBase.Controls.Add(lblArr[i, j]);
xpos += 0;
ypos += lblArr[i, j].Height;
}
xpos += 35;
ypos = 0;
}
}
</code></pre>
<p>As I am trying to find out what particular mouse button was pressed on a label in an array, I thought this method might work:</p>
<pre><code>public int pnlArr_Click(object sender, MouseEventArgs e)
</code></pre>
<p>The error goes away if i change MouseEventArgs to EventArgs, but then this won't work anymore:</p>
<pre><code>if (e.Button == MouseButtons.Left)
</code></pre>
<p>Any ideas? all help is much appreciated.</p>

Android TextView update

<p>Hi
I am trying to update a textview to notify the user when the GPS coordinates have been logged.
My problem is that I need to access the location infomation from another class and I cannot directly edit the textview from anything apart from the onCreate class.</p>
<p>here is my code:</p>
<pre><code>public class Location extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LocationManager mlocManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
LocationListener mlocListener = new MyLocationListener();
mlocManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, 0, 0, mlocListener);
}
public class MyLocationListener implements LocationListener
{
private final String TAG = null;
@Override
public void onLocationChanged(android.location.Location location) {
// TODO Auto-generated method stub
location.getLatitude();
location.getLongitude();
String Text = "My current location is: " + "Latitud = " + location.getLatitude() + "Longitud = " + location.getLongitude();
try
{
File root = Environment.getExternalStorageDirectory();
File gps = new File(root, "log.txt");
BufferedWriter out = new BufferedWriter(
new FileWriter(gps,true)) ;
TextView tv = (TextView)findViewById(R.id.textView1);

Java Grouping Images
|
<p>I'm working on a game and had someone propose a challenge for me that I am having trouble solving so I am now turning to the stack overflow community for some help. I am trying to create a game similar to Tanks. I currently have two images (the tank body and tank arm) that I move based on two lines of code. They challenged me to create a separated class for the tank where I upload both images but am only required to draw it onto my game panel once. That is, I will have the tank body and tank arm in the class and can do whatever I need to do to them in there, but when I go to draw it onto my game scree panel, I am only required to write one line of code that simply draws on that class.</p>
<p>For Example: </p>
<pre><code>g.drawImage(tank1, nX1, nY1, null)
</code></pre>
<p>Rather than:</p>
<pre><code>g.drawImage(tank1, nX1, nY1, null)
g.drawImage(tank1, nX1, nY1, null)
</code></pre>
<p>Any links or ideas as to what to do would be appreciated. Example code would be even better.</p>

How might a List<T> be reset?
|
<p>I have an object I create and stick in a collection:</p>
<pre><code>public class Level
{
private string id;
private List<LevelTypes> usableLevelTypes; // LevelTypes is an enum
private List<BlockTypes> levelMapping; // BlockTypes is also an enum
public Level(string id, List<LevelTypes> levelTypes, List<BlockTypes> incomingBlocks)
{
this.id = id;
this.usableLevelTypes = levelTypes
levelMapping = incomingBlocks;
}
</code></pre>
<p>Stepping through this, I can see each item being set properly. The object is then placed in a HashSet.</p>
<p>Another class then iterates through the HashSet calling each item's overloaded <code>.ToString()</code> method. </p>
<p>At this point I have all relevant variables in this class on my watch list. Everything within the object called is set properly. "id", "levelMapping" and all other variables that I have not listed including other <code>List<T></code>'s and int's contain their proper values except "usableLevelTypes", which is reported as being empty. </p>
<pre><code>public override string ToString()
{
var s = new StringBuilder();
s.Append("ID: " + id);
s.Append(" Level Types: " + usableLevelTypes[0].ToString()); // At this point,
// this list should have at minimum one value in it. However, it is empty and
// will throw an exception stating as much.
return s.ToString();
}
</code></pre>
<p>At no point is <code>.Clear()</code> called on the usableLevelTypes List and it is read-only. How could it be reset when other lists within the same object are not?</p>

Best practices for creating an application which will be upgraded frequently - C++
|
<p>I am developing a portable C++ application and looking for some best practices in doing that. This application will have frequent updates and I need to build it in such a way that parts of program can be updated easily.</p>
<ol>
<li>For a frequently updating program, creating the program parts into libraries is the best practice? If program parts are in separate libraries, users can just replace the library when something changes. </li>
<li>If answer for point 1 is "yes", what type of library I have to use? In LINUX, I know I can create a "<em>shared library</em>", but I am not sure how portable is that to windows. What type of library I have to use? I am aware about the DLL hell issues in windows as well. </li>

Are these really different functions? jQuery.extend()
|
<p>The jQuery documentation covers the function jQuery.extend()s twice, giving it different definitions. The first relates to extending the jQuery object itself: <a href="http://docs.jquery.com/Core/jQuery.extend#object" rel="nofollow">http://docs.jquery.com/Core/jQuery.extend#object</a>. The second relates to extend an input argument: <a href="http://docs.jquery.com/Utilities/jQuery.extend" rel="nofollow">http://docs.jquery.com/Utilities/jQuery.extend</a></p>
<p>Are these two usages of the same function, or are these actually different functions? I presume its the same function, but then I wonder why its documented twice as different functions.</p>

Android - How to get the mobile nunber when not stored in the SIM card
|
<p>I want to get the mobile number related with a SIM card. But I know that some celular operators doesn't store the number into the SIM card.</p>
<p>So use the code below will not return anything,</p>
<pre><code>TelephonyManager tm = (TelephonyManager)this.getApplicationContext()
.getSystemService(Context.TELEPHONY_SERVICE);
String phoneNumber = tm.getLine1Number();
</code></pre>
<p>Anyone knows any other way to get the mobile number?</p>
<p>Maybe some API that retrieves the number using the IMSI of the SIM Card, or maybe the mobile number is stored somewhere on the memory of the device.</p>
<p>One desperate way could be make some kind of request to the operator or carrier to ask for the mobile number for that IMSI, I don't know :)</p>
<p>any help will be appreciated :)</p>

PHP exceptions thrown in error handler are not caught by exception handler
|
<p>I use the following function to set my own error handler and exception handler.</p>
<pre><code>set_error_handler
set_exception_handler
</code></pre>
<p>The error handler transforms errors to exception. (throws a new exception)</p>
<p>But these exceptions are not caught by my own exception handler.</p>
<p>error handler example:</p>
<pre><code>function errorHandler($errno, $errstr, $errfile, $errline, $errcontext) {
throw new Exception("this was an error");
}
</code></pre>
<p>exception handler example:</p>
<pre><code>function exceptionHandler($e){
// don't get here when exception is thrown in error handler
Logger::logException($e);
}
</code></pre>
<p>(I think this can not work anyway)</p>
<p>Should this work ?</p>
<p>Or can someone explain why it can not work ?</p>
<p>EDIT:</p>
<p>I made some tests, and it should work. </p>
<p>Exceptions thrown in the ErrorHandler are getting caught by the ExceptionHandler
And Errors triggered in the ExceptionHandler are getting processed by the ErrorHandler </p>
<p>Just FYI.</p>
<p>My Problem has to be elsewhere</p>
<hr>
<p>EDIT:</p>
<p>I Still have not found why the exception thrown in my errorHandler is not caught by my exceptionHandler.</p>
<p>For Example when I have this somewhere in the code.</p>
<pre><code>trigger_error("this is an error"); // gets handled by the errorHandler
throw new Exception("this is an exception"); // gets handler by the exceptionHandler
</code></pre>
<p>The error gets handled by the errorHandler but the exception thrown in the errorHandler gets not handled by the exceptionHandler.</p>
<p>But if I throw an exception at the same place where I trigger an error, this exception gets handled by the exception handler. </p>
<p>(Hope it is somehow understandable what I mean)</p>
<p>I'm clueless here.
Any Ideas where I have to look for the Problem?</p>

vectorOfPointers.reserve(n);
</code></pre>
<p>For up to which number <strong>n</strong> does the above mentioned program run in <strong>O(1)</strong> ? </p>
<p>Let us suppose that for a laptop running 32 bit Ubuntu with 3 gigabytes of memory, not running any other programs. Is it tens, thousands, millions? What information does one need to know to be able to asses such a question? Is there a way to find out without running any experiments?</p>
<p>I have never studied anything about operating systems but in my imagination, the operating system allocates memory in just 2 steps. It determines the pointer to start the chunk and the pointer of the end of the chunk. The situation can be more complicated because the system may have to tidy up in order to get a big enough chunk of memory. But if we suppose that the system runs just this one program, how can we estimate the time needed? Are there some other aspects to be considered, besides the fragmentation of memory?</p>
<p>EDIT:</p>
<p>sorry, I didn't make my question clear. It is important to consider, that the vector is empty before calling reserve, so no copying of data is required.</p>

How do I convert "1.20E+07" to a float?
|
<p>I can't convert the text, "1.20E+07" to a float.</p>
<p>I've tried:</p>
<pre><code>info = CultureInfo.GetCultureInfo ("en-US");
float.TryParse ("1.20E+07", NumberStyles.AllowExponent, info, out cellValue);
</code></pre>

NSTimer to update label
|
<pre><code>self.timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(updateTimerDisplay) userInfo:nil repeats:YES];
[runLoop addTimer:self.timer forMode:NSRunLoopCommonModes];
</code></pre>
<p>This code-snippet is copied from my viewDidLoad method, so it is runned from the main-thread. All it do is to call a method to update a label. </p>
<p>I thought I need to have a own thread for doing this, but after getting help on this at SO I figured out that I did not. </p>
<p>However, I do not understand the <code>NSRunLoopCommonModes</code>. Why does it work?</p>
<hr>
<p>AND the timer updates the label which is a "digital counter" which is on the same screen as a tableview so it CAN'T stop the timer even if the user holds the screen.</p>
<p>Thanks.</p>
