How to pass $this to non-object function

<p>When I pass <code>$this</code> to a function, I got error message like this, <code>The function does not exists.</code> </p>
<pre><code>// In class A

Do($this);
}
function t()
{

function t()
{
}
}
// Some where in .inc.php file

$obj->t();

<p>Actually, I have many classes inherit from one base class. All those class have some functions in common. I need a function to deal them all.</p>

Performance of "enhanced" for loop vs "traditional" for loop?

<p>Java 5 brought about the additions of "enhanced" for loops, providing better syntax that was more concise, and less prone to errors or syntactical bugs by programmers. In addition, it seems to be easier to use. </p>
<p>However, I've heard there are performance enhancements with the "enhanced" for loop as well. Is this true, and if so, what are the performance differences between the two styles of looping? </p>

sanitizing a string before serializing and inserting to db

<p>example: "test" would be</p>
<blockquote>
<p>"string";s:4:"test";</p>
</blockquote>
<p>However problems arise when the user submits quotes and some other characters like ;
Of course I escape the string first, but the serialized data cannot be unserialized.</p>
<p><code>htmlentities</code> before submitting to db wouldn't work either since <code>;</code> messes up the data...</p>

Is there a way to create custom UIDataDetectorTypes?
|
<p>What I am trying to do is create tooltip functionality so that certain words in my instructional app can be tapped and the definition pops up. For the popup part I plan on using code from “AFInformationView” which provides bubbles on the iPhone.</p>
<p>The part I'm struggling with is how to associate A particular word's location with the bubble. Currently I have the text on a UILabel that is on a custom UITableCell. Since I calculate the row height on the fly with:</p>
<pre><code>[textToUse sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:CGSizeMake(stop-start, 500)];
</code></pre>
<p>I'm not sure what the coordinates for a specific word will be. I was thinking that if I created a custom DataDetectorType that could be the fix.</p>
<p>If anyone knows how to do this or has any other ideas I would be happy to hear them.</p>
<p>Thanks,</p>

My LINQ sort does not seem to be sorting the way I asked it to
|
<p>I have this code:</p>
<pre><code>var query = _cityRepository.GetAll(
u => u.PartitionKey == pk &
u.RowKey.CompareTo(lowerBound) >= 0 &
u.RowKey.CompareTo(upperBound) < 0)
.OrderBy(item => item.RowKey.Substring(0, 3))
.ThenBy(item => item.ShortTitle)
.Select((t, index) => new City.Grid()
{
PartitionKey = t.PartitionKey,
RowKey = t.RowKey,
Row = index + 1,
ShortTitle = t.ShortTitle,
Created = t.Created,
CreatedBy = t.CreatedBy,
Modified = t.Modified,
ModifiedBy = t.ModifiedBy
})
.ToList();
</code></pre>
<p>When I look at the data coming out I find this for the first two rows:</p>
<pre><code>RowKey = 0101004O , ShortTitle = "Access 1"
RowKey = 0103004M , ShortTitle = "Access 2"
RowKey = 0101004K , ShortTitle = "xxx"
</code></pre>
<p>When testing I simplified this to:</p>
<pre><code> var query1 = _cityRepository.GetAll()
.OrderBy(item => item.RowKey.Substring(0, 3))
.ThenBy(item => item.ShortTitle);
</code></pre>
<p>and the order is the same. Still the RowKey does not seem to be in the right order. </p>
<p>It is supposed to sort on the first four characters of the rowkey and then on the ShortTitle. </p>
<p>Can anyone see why this is not working. I have looked hard but I can't see why the OrderBy and ThenBy doesn't seem to work correctly.</p>

c++ vectors not like arrays
|
<p>I've been getting my head round c++ for a few months, and have
been directed by google to stack overflow most of the time
for c++ queries. I noted frequently exhortations of the type
"why don't you use a vector", and was inspired to do just that.</p>
<p>So, primarily to get the minor benefits of automatic memory deallocation,
and being able to write typed comparison functions for sorting.
I switched an array of pointers to objects to being a vector.
Now I thought (incorrectly it seems) that vectors could be used
more or less like arrays, and hence I initialized thusly:</p>
<pre><code>cluster clusters[LOTS];
vector<cluster *> pclust;
pclust.reserve(numClust);
for (int i=0; i<numClust; ++i)
pclust[i] = clusters + i;
</code></pre>
<p>No complaints from the compiler.
Then some time later I need to sort the vector on some
attribute of the cluster object. So:</p>
<pre><code>std::sort(pclust.begin(), pclust.end(), ClusterCompareNumSegs);
</code></pre>
<p>Again no problems compiling. Except the vector doesn't
get sorted. It turns out that vector.size() is zero,
and of course my initialization should have been </p>
<pre><code>pclust.push_back(clusters + i);
</code></pre>
<p>Now that's easy to fix, but I am confused, because the initial
incorrect assignment was working. I successfully iterated through
the vector - using the array syntax, like so:</p>
<pre><code>for (clustind=0; clustind < numClust; ++clustind) {<br>
cluster *cl = pclust[clustind];
...happily access *cl...
</code></pre>
<p>And it all worked fine. So I'm just wondering what's going on.
Presumably in my initial assignments, I was trying to access
elements not yet in the vector (I was trying to put them in),
and the vector was throwing exceptions that I was ignoring.
But nonetheless, when referencing the locations, the pointers
were there. Can anyone provide enlightenment?</p>

Organizing my JavaScript function library
|
<p>Over time, I created a bunch of various JavaScript functions. Most of them are static functions, and do things like modify the appears of a date, create the select menu HTML from an array, etc.</p>
<p>I currently have them all in a file called "general.js" which is in turn directly called by my HTML page, and each of them look something like:</p>
<pre><code>function modifyDate(data){....}
function makeArray(arr){....}
</code></pre>
<p>And then I use them as:</p>
<pre><code>alert(modifyDate("12/14/2013"));
</code></pre>
<p>I am thinking this is a bad idea as it might conflict with other libraries. Instead, I am thinking of something like the following:</p>
<pre><code>myLibrary={};
myLibrary.modifyDate= function(data){....}
myLibrary.makeArray= function(arr){....}
</code></pre>
<p>And them use them as:</p>
<pre><code>alert(myLibrary.modifyDate("12/14/2013"));
</code></pre>
<p>Note that I am kind of making this up as I go. Please provide advice how I should best organize my JavaScript library. Thank you</p>

Activity indicator not showing when there is loop code?
|
<p>I am showing an Activity indicator in welcome screen as well as main screen. It is working fine in welcome screen. In main view, there is a 'for' loop code which does some task for 16 times. At this time, device looks like a bit hang, to avoid that i want to show activity indicator. When i add the standard activity code in main screen during some loop(16 times) code going on, i'm not observing the set activity indicator show. It comes only after the loop finished. I tried giving some delay before doing loop code, but still doesn't show during expected time. Otherwise user may think that my app hangs the device, so i want to show activity indicator at that time.</p>
<p>Any suggestions to resolve this are welcome !</p>
<p>thanks.</p>

Is it possible to simulate an increased rate of passage of time in Android?
|
<p>I searched for a while, but couldn't find the same question.</p>
<p>I am writing an application where I need to schedule a lot of alarms a day, and then do different things throughout the day, and I'd love to be able to test, say 24 hours in 24 minutes, or something along those lines. </p>
<p><strong>Is it possible to simulate a faster passage of time, either in emulator, or on-device?</strong> </p>
<p>If it is, this would be great for me to be able to test these things without losing development time. As it is, I'm writing them in a way that I think will work, doing spot tests, and then running the program myself to verify that the behavior is correct, but it greatly slows my development time to have to wait a day or two between seeing a poor behavior, and then trying to fix it and retesting it. Any help would be greatly appreciated!</p>

Newbie: Checking to see if radio button is checked on form initialization. What does this code mean?
|
<p>I am a javascript novice. I'm trying to build a complex form whilst simultaneously learning JS and JQ... not an easy task. This code works, but I don't know what two lines do, so I thought I'd ask here.</p>
<p>What this code does is loop through an array to see if a radio button checkbox has been checked as yes or no. It runs at initialization when a user revisits the form he/she is filling out. The code is attached to a textfield element which unhides if myRadioButton is yes, stays hidden if no.</p>
<p>I do not know what lines 5 and 6 do (beginning with the second if statement). Would some knowledgable person please be so kind as to transcribe those lines into a couple of sentences, kind of like they do in tutorials? I would really appreciate it!</p>
<pre><code>var rbVal = "";
var rbBtn = JQuery("[name=\"myRadioButton[]\"]");
for (var i = 0; i < rbBtn.length; i++)
if (rbBtn[i].checked) {
if (rbVal != "") rbVal += ",";
rbVal += rbBtn[i].value;
}
if( rbVal != "yes" ){
doSomething;
}
else {
doSomethingElse;
}

jQuery Star Rating using Select Option dropdown
|
<p>I need a little help here... last several hours been trying to figure this out, and getting nowhere.</p>
<p>I found this simple jQuery Star rating system that i'd like to use, the original coding was using an INPUT field but I changed it to being used with a Select Option Dropdown. When it's displayed on the left you have the dropdown and to the right you have the default STARS. Now when you click on the STARS, the dropdown options change... which is good, that part I want to keep, However when you use the actual Dropdown the stars wont change... here is the coding...</p>
<pre><code><select name="my_input" id="rating_simple">
<option value="0" selected="selected"></option>
<option value="1">Poor</option>
<option value="2">Below Average</option>
<option value="3">Average</option>
<option value="4">Good</option>
<option value="5">Excellent</option>
</select>
</code></pre>
<p>JavaScript</p>
<pre><code>$(function() {
$("#rating_simple").webwidget_rating_simple({
rating_star_length: '5',
rating_initial_value: '',
rating_function_name: '',
directory: 'rating-system/'
});
});

Building New Product: ASP.NET/MVC vs SharePoint 2010
|
<p>Hi I met an investor who wants a new product to sells to other companies. We agreed to make it SaaS, but we're arguing over three options:</p>
<ul>
<li>SaaS product made by ASP.NET</li>
<li>Saas product Made up of huge SharePoint server</li>
<li>SharePoint add-on (as group of solutions/web parts)</li>
</ul>
<p>I can't disclose the product exactly, but, it is about collaboration and involves many interaction between users. That is the reason why we have SharePoint as an option, also because a user might optionally create web pages (single home page).</p>
<p>Some users dont want SaaS. There is possibility of hosting the product at a company server (some want their 'sensitive' data hosted locally).</p>
<p>So my question is: which one would you choose as SAAS with ability to make it a locally hosted solution (without losing your code of course).</p>

hiding/removing selected from select option list for multiple select tags with same list
|
<p>let's say i have 4 select tags that uses the same option choices. i wanted to remove the selected options from the choices. currently i tried this code:</p>
<pre><code> function connect(val)
{
$(".option").show();
$(".selectbox").each(function(i) {
var obj = $("option[value='" + $(this).val() + "']");
alert(obj);
if($(this).val() != "") obj.remove();
});
}
</code></pre>
<p>i have this for the select tags:</p>
<pre><code>for()
{
<select id = "sc" name = "connect_array[]" class="input-select" onchange = "connect(this.value)">
for()
{
<option></option>
}
</select>
}
</code></pre>
<p>But what actually happens is the it only removes the options of the first select and the first select ends up with no choices when all choices where chosen by the other select tags, also you can still see the full choices in the other select tags.</p>
<p>thank you.</p>

Specialization of casting operator to template argument
|
<p>I can't find this question answered in any other place, so I finally decided to ask.
I have a C++ templated class that includes a casting operator to the type of one of the arguments:</p>
<pre><code>template <class E, class B>
class bar {
private:
B innerVal_;
[...]
public:
/* Casting to the type of the 2nd template argument */
operator B() const { return innerVal_; }; // default implementation provided
};
</code></pre>
<p>However, I need to provide a specialization of this casting operator for some specific template arguments, for instance:</p>
<pre><code>template<>
bar<concreteType,int>::operator int() // <-- whoops, error!
{ [...] }
</code></pre>
<p>The thing is that, no matter how I specify the syntax of the casting operator, gcc consistently returns me an error referred to the declaration of the function. The most common one is:</p>
<blockquote>
<p>error: template-id ‘operator int<>’ for ‘bar< concreteType, int>::operator int()’ does not match any template declaration.</p>
</blockquote>
<p>Which I got with these lines:</p>
<ul>
<li>Defining the casting operator as "operator int()"</li>
<li>Using "operator typeB()", after declaring in the original template a line "typedef B typeB;"</li>
</ul>
<p>I also played around with the "typename" keyword, with template brackets, and made some other desperate attempts. All of them result in bizarre errors --that I'm not going even to paste here.</p>
<p>Am I losing some obvious detail? Do you have any hint/pointer for me? Any help will be useful.</p>

Android UI does not get refreshed with Data from DB
|
<p>I am creating an activity which paints the UI (TableLayout displayed with data from MYSQL database). The UI has a button so on clicking that, it takes to a different activity and then it comes back to the parent. My issue is that, when it comes back to the parent, the parent screen does not show the updated data.</p>
<p>to be more clear, the parent is a view screen with an add button. Clicking on Add button takes to a form where the user fills in data and submits. After submit of the Add screen, the parent screen(view screen) is invoked again. Here the table layout is not refreshed with the newly added record. </p>

When creating the page (using a PHP script) some of the rows have their cells filled with text while the rest have their cells filled with text boxes. What I want to do is allow the user to fill any number of the rows with text boxes and then submit them to a PHP script.</p>
<p>When the user clicks submit, I want to get all the rows which the user has filled in (essentially the rows with filled textboxes) and submit just the data in those text boxes to the script, ideally in a 2D array where each row of the array represents a row of the table?</p>

<p>I have this code that works as posted:</p>
<pre><code>$('#cs_tableVideoListings tbody tr td').each(

$(this).css('border-bottom','2px solid gray');
})
</code></pre>
<p>the issue is that "gray" is too dark. When I try #333 or any hex number, it doesn't work at all.</p>
<p>I only need to apply the bottom border, so using "border-bottom" : "2px solid #333" (note colon) doesn't work as that syntax seems to only work when applying multiple styles.</p>
<p>So, I'm wondering at to apply a hex color in the above code w/o getting ridiculous about assigning variables and such.</p>
<p>Thanks </p>

Find and replace URLS in a block of text, return text + list of URLS
|
<p>I'm trying to find a way to take a block of text, replace all URLs in that text with some other text, then return the new text chunk and a list of URLs it found. Something like:</p>
<pre><code>text = """This is some text www.google.com blah blah http://www.imgur.com/12345.jpg lol"""
text, urls = FindURLs(text, "{{URL}}")
</code></pre>
<p>Should give:</p>
<pre><code>text = "This is some text {{URL}} blah blah {{URL}} lol"
urls = ["www.google.com", "http://www.imgur.com/12345.jpg"]
</code></pre>
<p>I know this will involve some regex - I've found some seemingly good URL detection regex here:
<a href="http://www.regexguru.com/2008/11/detecting-urls-in-a-block-of-text/" rel="nofollow">http://www.regexguru.com/2008/11/detecting-urls-in-a-block-of-text/</a></p>
<p>I'm pretty rubbish with regex, though, so I'm finding that getting it to do what I want with python quite tricky. The order that the URLs are returned in doesn't really matter.</p>
<p>Thanks :)</p>

ViewFlipper caching issue
|
<p>The views are not cached in a ViewFlipper. Is there a way wherein we can get an image of the view and show it to user so that he sees the Ui as we see on Home scrren(when we swipe the previous view also moves along and when we lift our finger, only then the next view is shown completely.)</p>
<p>What I want to do is that when the user starts moving his finegr on screen, the view should also move along(create an image of view).</p>
<p>I am not getting to do this, as when we swipe the present view goes and next view comes, we do not get both visible when we r moving our finger on screen.</p>
<p>Please if anyone gets what I am trying to do, do help me.</p>

C# - Form.Show locks up the application on the 3rd attempt - why?
|
<p>So I have a a button that simply shows and hides a window, pretty straightforward.</p>
<p>As such:</p>
<pre><code>public static void LaunchUI()
{
if (!Forms.AllForms.UI.Visible)
{
Forms.AllForms.UI.MdiParent = MyApp.Forms.AllForms.MainForm;
Forms.AllForms.UI.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
Forms.AllForms.UI.Show();
}
}
public static void CloseUI()
{
if (Forms.AllForms.UI.Visible)
Forms.AllForms.UI.Hide();
}
</code></pre>
<p>I can open and close the window twice, then, on the 3rd time, it locks up on Forms.AllForms.UI.Show(). I have 0 idea why, it is being opened from the main thread.</p>
<p>Anyone know what I'm doing wrong?</p>
<p>Thanks!</p>

My first python program: can you tell me what I'm doing wrong?
|
<p>I hope this question is considered appropriate for stackoverflow. If not, I'll remove the question right away.</p>
<p>I've just wrote my very first python program. The idea is that you can issue a command, and it's gets sent to several servers in parallel.</p>
<p>This is just for personal educational purposes. The program works! I really want to get better at python and therefore I'd like to ask the following questions:</p>
<ol>
<li>My style looks messy compared to PHP (what I'm used to). Do you have any suggestions around style improvements.</li>
<li>Am I using the correct libraries? Am I using them correctly?</li>
<li>Am I using the correct datatypes? Am I using them correctly?</li>
</ol>
<p>I have a good programming background, but it took me quite a while to develope a decent style for PHP (PEAR-coding standards, knowing what tools to use and when).</p>
<p>The source (one file, 92 lines of code)</p>

Pass list of ids between forms
|
<p>I have an ASP.NET c# project.</p>
<p>I have to pass a list of values (id numbers such as "23,4455,21,2,765,...) from one form to another. Since QueryString is not possible because the list could be long, which is the best way to do it?</p>
<p>Thanks in advance.</p>
<p>Thanks for all your answers, you are helping a lot !!!
I decided to do this:</p>
<p>On the first form:</p>
<p>List lRecipients = new List();
.....
Session["Recipients"] = lRecipients;</p>
<p>On the final form:
List lRecipients = (List)Session["Recipients"];
Session.Remove("Recipients"); </p>

Sorting a table with foreach?
|
<p>Not sure if this is possible, but I'd like to sort a foreach table by a column, highest to lowest. The last column has a <code>count</code> formula to calculate <code>PilotData::getAllPilotsByHub</code> and I'd like the row with the highest number to be always first in the table.</p>
<pre><code><?php
$allhubs = OperationsData::GetAllHubs();
foreach($allhubs as $hub)
{
?>
<tr>
<td align="center"><?php echo $hub->icao; ?></td>
<td align="center"><?php echo $hub->name; ?></td>
<td align="center"><?php echo count(PilotData::getAllPilotsByHub(''.$hub->icao.'')); ?></td>

Read in a txt file separating and storing variables (String , Double and int) for later use
|
<p>Beginner java programmer ,
I am Looking for a way to read in a txt file (output from a till) while manipulating certain data that relates to the shift type, transaction type and cost to give me my desired result.</p>
<p>Any help would be greatly appreciated.</p>
<p>Example line in txt document:</p>
<p>"<strong>CARD</strong>","<strong>05-07-2012</strong> 10:32:42","Laminate A4",10,<strong>10</strong>,"<strong>NIGHTSHIFT</strong>",1486510814,False,130</p>
<p>So the relevant information I need is in <strong>bold</strong> the rest of the information in the text line is irrelevant.</p>
<p>Where I need to find the total <strong>cost</strong> of all <strong>card</strong> transactions made <strong>yesterday</strong> (05-07-2012) on <strong>Nightshift</strong>.</p>
<p>Heres where I have gotten so far, I have tried to split at night shift. Also thought about using an array as well and storing each value to its own variable but found this too difficult.</p>
<pre><code>import java.io.File;
import java.io.FileNotFoundException;
import java.text.SimpleDateFormat;
import java.util.*;
public class Finder{
public static void main (String args[]) throws FileNotFoundException
{
Calendar today = Calendar.getInstance();
SimpleDateFormat formatter=
new SimpleDateFormat("dd-MM-yyyy");
today.add(Calendar.DATE, -1);
String yesterday = formatter.format(today.getTime());
Scanner sc = new Scanner(new File("textdocument.log"));
while(sc.hasNextLine()) {
String[] numstrs = sc.nextLine().split(yesterday + "\"NIGHTSHIFT\""); // split by "
for(int i = 0; i < numstrs.length; i++)
{
System.out.println(numstrs[i]);
System.out.println();
}
}
}
}
</code></pre>
<p>DESIRED OUTPUT:</p>
<p>Nightshift Totals On 05-07-2012</p>
<p>Cash total $20</p>
<p>Card total $40</p>
<p>Eftpos total $20</p>
<p>I hope I have asked clearly.</p>
<p>Thanks</p>

Why use static_cast rather than dynamic_cast in here?
|
<p>I copy the following text from the book More Effective C++.</p>
<p><strong>Item 31: Making functions virtual with respect to more than one object.</strong> </p>
<pre><code>class GameObject { ... };
class SpaceShip: public GameObject { ... };
class SpaceStation: public GameObject { ... };
class Asteroid: public GameObject { ... };
</code></pre>
<p>The most common approach to double-dispatching returns us to the unforgiving world of virtual function emulation via chains of if-then-elses. In this harsh world, we first discover the real type of otherObject, then we test it against all the possibilities: </p>
<pre><code>void SpaceShip::collide(GameObject& otherObject)
{
const type_info& objectType = typeid(otherObject);
if (objectType == typeid(SpaceShip)) {
SpaceShip& ss = static_cast<SpaceShip&>(otherObject);
process a SpaceShip-SpaceShip collision;
}
else if (objectType == typeid(SpaceStation)) {
SpaceStation& ss =
static_cast<SpaceStation&>(otherObject);
process a SpaceShip-SpaceStation collision;
}
...
}
</code></pre>
<p>Here is the question:</p>
<p>Q1> Why we use static_cast here rather than obvious dynamic_cast? </p>
<p>Q2> Are they same in this case?</p>
<p>thank you</p>
<p>// updated //</p>
<p>In fact, I am more interested in question 2. </p>
<p>For example,</p>
<pre><code>class base {};
class subclass : public base {};
base *pSubClass = new subclass;
subclass *pSubClass1 = static_cast<subClass*> (pSubClass);
</code></pre>
<p>// does the static_cast do the job correctly in this case although I know we should use dynamic_cast here?</p>
