Checkbox disabled not returning result from stored checkbox array
I am storing all checkboxes what my div has in to a variable, later i am
finding disabled from the stored variable, but i am not get proper result,
instead if I find separately I am getting proper result..
what why i am not find the disabled from my stored variable?
here is my code:
var checkedBoxes = $(".locale-container .panel ul
li").find("input:checkbox"),
disabledBoxes = checkedBoxes.find("input:checkbox:disabled");
// not getting
But "disabledBoxes" not getting result from checkBoxes.
In case if I do like this:
var checkedBoxes = $(".locale-container .panel ul
li").find("input:checkbox"),
disabledBoxes = $(".locale-container .panel ul
li").find("input:checkbox:disabled"); // it works
so how can i filter or get the appropriate checkboxes from stored variable?
Thanks in advance

How does compiler resolves virtual functions accessing non-virtual data members C++
How does compiler resolves virtual functions accessing non-virtual data
members C++
I was reading about the C++ Objects when I got this doubt. Suppose there
are two classes
class X
{
virtual int def() { };
}
class Y
{
virtual int abc() { };
}
class Z : public X,public Y
{
virutal int abc() { return a };
int a;
}
Now what I understand is both Y and Z have the reference to Z::abc() in
their virtual tables which helps to resolve the correct function to call.
Consider
Y *y = new Z;
Z *z = new Z;
y->abc() // I understand this is done by reaching the vptr of y by this =
this + sizeof (X)
and z->abc() // z has its own vptr reachable
My understanding is that in both the cases the "this" pointer is passed
and after finding out the correct abc() to call, how does the programm
reach the int value "a"?
How does the compiler calculate the address of " int a" correctly based on
type of the object passed?

Access to an array element with PHP
Access to an array element with PHP
To avoid multiple mysql SELECT queries I try to take the SELECT out of the
foreach-loop.
The query is
SELECT o.orders_id,
o.date_purchased,
o.orders_status,
ot.text AS order_total,
os.orders_status_name
FROM " . TABLE_ORDERS . " o
JOIN " . TABLE_ORDERS_TOTAL . " ot ON (o.orders_id = ot.orders_id AND
ot.class = 'ot_total')
JOIN " . TABLE_ORDERS_STATUS . " os ON (o.orders_status =
os.orders_status_id AND os.language_id = " .
(int)$_SESSION['languages_id'] . ")
WHERE o.customers_id = " . (int)$_SESSION['customer_id'] . "
ORDER BY orders_id DESC
As the result I get the array called $history_result['RESULT'] and it
looks like
Array
(
[0] => Array
(
[orders_id] => 309
[date_purchased] => 2013-10-02 15:49:54
[orders_status] => 1
[order_total] => 9,00 €
[orders_status_name] => Offen
)
[1] => Array

[date_purchased] => 2013-10-02 15:39:54

[orders_status] => 1
[order_total] => 9,00 €
[orders_status_name] => Offen
)
)
In the following foreach-loop is the next MySql-Query
foreach ($history_result['RESULT'] as $history) {
$trackings = $db->result("-- 03 account_history_info.php
SELECT o.ortra_parcel_id,
c.carrier_tracking_link,
c.carrier_name
FROM " . TABLE_ORDERS_TRACKING . " o
JOIN " . TABLE_CARRIERS . " c ON o.ortra_id = c.carrier_id
WHERE ortra_order_id = " . $history['orders_id']
);
}
How can I access directly to the array element 'orders_id' so that I could
create an SQL statement like
$trackings = $db->result("-- 03 account_history_info.php
SELECT o.ortra_parcel_id,
c.carrier_tracking_link,
c.carrier_name
FROM " . TABLE_ORDERS_TRACKING . " o

only a few are updated, but what happens is that, you need to press the

Why use typedef for iterators in template classes
Why use typedef for iterators in template classes
I read the following post: Why use typedef-typename in templates
I am reading up on some material which says you must have public typedef
for the following private nested class
template<typename T>
class list
{
private:
class my_private_it
{
public:
...
};
public:
typedef my_private_it iterator;
// should this be:
// typedef typename my_private_it iterator;
...
iterator begin(){return iterator(this)};
iterator end(){return iterator(NULL)};
};
Now from the aforementioned link, I understand, the typename is to help
the compiler deduce that it is infact working with types and not values
for certain dependent names. But why do people use the typedef? Is this
compiler requirement or standard requirement. Please note I understand the
typename part , but not the typedef part.

I'm trying to get icon-remove to sit top right in the li.
btn-comment and btn-youtube should be centered in the li, vertically and

The problem I am having is that the icon-remove icon is causing the

Clone closest row from a href
Clone closest row from a href
I have a code that is supposed to duplicate the row that I specify. My
table is made dynamically so I am not able to define an id. I want to be
able to click a button on the specified row and find the closest tr to
duplicate.
The code that is supposed to duplicate is:
function cloneRow()
{
var row = $(this).closest('tr'); // find row to copy
var table = document.getElementById("ScannedItems");
var clone = row.cloneNode(true); // copy children too
clone.id = "newID";
table.appendChild(clone);
}
I am needing to change var row = $(this).closest('tr'); to something else
but I don't know what to change it to so I can get the closest tr from the
a href that is clicked.
Or just duplicate the same row that the a is clicked on.
The a href looks like this
<a onclick='cloneRow();'><span class='glyphicon glyphicon-plus'
style='padding-right:15px;'>

Our problem is the entire request, beginning to end uses multiple
connections to different databases and we want to guarantee data integrity
by using TransactionScope (which starts as a light weight transaction,
then is promoted to a distributed transaction, once a second connection is
established).
The reason we need a single thread per request, is when you attempt to
dispose a transaction on a thread different than the thread that started
it, it throws an exception stating it must be disposed on the same thread
that started it. Then the transaction leaks, and nothing gets committed,
and it slowly brings the machine to a grinding halt.
Is anyone aware of any setting in IIS 7 that will force it to use a single
thread per request, and not allow it to switch threads during a request?
Or go back to a legacy thread model?

Returning value
Returning value
I have some difficulties with understanding what is really done behind
returning values in C++.
Let's have following code:
class MyClass {
public:
int id;
MyClass(int id) {
this->id = id;
cout << "[" << id << "] MyClass::ctor\n";
}
MyClass(const MyClass& other) {
cout << "[" << id << "] MyClass::ctor&\n";
}
~MyClass() {
cout << "[" << id << "] MyClass::dtor\n";
}
MyClass& operator=(const MyClass& r) {
cout << "[" << id << "] MyClass::operator=\n";
return *this;
}
};
MyClass foo() {
MyClass c(111);
return c;
}
MyClass& bar() {
MyClass c(222);
return c;
}
MyClass* baz() {
MyClass* c = new MyClass(333);
return c;
}
I use gcc 4.7.3.
Case 1
When I call:
MyClass c1 = foo();
cout << c1.id << endl;
The output is:
[111] MyClass::ctor
111
[111] MyClass::dtor
My understanding is that in foo object is created on the stack and then
destroyed upon return statement because it's end of a scope. Returning is
done by object copying (copy constructor) which is later assigned to c1 in
main (assignment operator). If I'm right why there is no output from copy
constructor nor assignment operator? Is this because of RVO?
Case 2
When I call:
MyClass c2 = bar();
cout << c2.id << endl;
The output is:
[222] MyClass::ctor
[222] MyClass::dtor
[4197488] MyClass::ctor&
4197488
[4197488] MyClass::dtor
What is going on here? I create variable then return it and variable is
destroyed because it is end of a scope. Compiler is trying copy that
variable by copy constructor but It is already destroyed and that's why I
have random value? So what is actually in c2 in main?
Case 3
When I call:
MyClass* c3 = baz();
cout << c3->id << endl;
The output is:
[333] MyClass::ctor
333
This is the simplest case? I return a dynamically created pointer which
lies on heap, so memmory is allocated and not automatically freed. This is
the case when destructor isn't called and I have memory leak. Am I right?

**</DocumentStatus>**
</Invoice>
so i need to know how can i add <DocumentStatus> after
<InvoiceNO></InvoiceNO>, and </DocumentStatus> after

Cannot Change TextView Value Inside Fragment From FragmentActivity
Cannot Change TextView Value Inside Fragment From FragmentActivity
I'm developing a simple app based on viewPager. I'm trying to change the
text in a textView inside a fragment from the mainActivity. I tried to
call textV.setText(String) right after the init() method(where the
fragment is instantiated), but the OnCreateView is executed much later, so
the reference to textV is null in that moment. The textV textView is
placed in tab0layout.xml, and become != null when the layout file is
inflated, and it is referenced inside OnCreateView method of Fragment0.
How can I get a valid reference of textV inside my MainActivity? Setting
the text from within the OnCreateView works fine, but I need it available
in the mainActivity.

Order_by in sqlalchemy with outer join
Order_by in sqlalchemy with outer join
I have the following sqlalchemy queries:
score = Scores.query.group_by(Scores.email).order_by(Scores.date).subquery()
students = db.session.query(Students,
score.c.id).filter_by(archive=0).order_by(Students.exam_date).outerjoin(score,
Students.email == score.c.email)
And then I render the things with:
return render_template('students.html', students=students.all())
Now, the issue is that I want the last score for a student to be
displayed, as there are many of them corresponding to each user. But the
first one seems to be returned. I tried some sortings and order_by on the
first query, score, but without success.
How can I affect and pick only one latest result from the "score" to be
paired with the corresponding row in "students"?
Thanks!

The problem is that if I click on a tag to write some other text in it,
the data appear at the end of the array. But I want that the data will be
replaced at the same position in the array. As you can see I also tried to
work with splice(). But I don't know how to push the new data at the
position where the deleted text was living. Have you any idea for that?

As you can see i've mentioned 3 processes and 3 threads in daemon mode.
Now, when i send 1000's of request after serving some set of requests,
apache should kill the interpreter and reinitiate a new one. Apache tries
to do this, however the killed processes stays back in the memory as
subprocesses of init(PID-1). Thus occupying memory. Eventually number of
processes increases and system crashes due to lack of memory.
So, what can be done to avoid this ? Am i doing anything wrong in
application itself ?
Please help me out.

As you can see i've mentioned 3 processes and 3 threads in daemon mode.
Now, when i send 1000's of request after serving some set of requests,
apache should kill the interpreter and reinitiate a new one. Apache tries
to do this, however the killed processes stays back in the memory as
subprocesses of init(PID-1). Thus occupying memory. Eventually number of
processes increases and system crashes due to lack of memory.
So, what can be done to avoid this ? Am i doing anything wrong in
application itself ?
Please help me out.

KineticJS layer.get() finds non existent shapes
KineticJS layer.get() finds non existent shapes
I'm experiencing some troubles with KinectJS when I try to get a rectangle
using its id. Take a look at my code here:
var obj = null;
obj = myLayer.get("#asd");
if (obj != null) {
console.log(obj);
}
There are no shapes with #asd - but obj still isn't null. When I log it in
the console i get:
[each: function, toArray: function, on: function, off: function, remove:
function…]
What I want is to check if it found the shape with id #asd. How can I do
that?

Unload a device
Unload a device
I made a device driver. But my system crashed at the moment when it was
deleting the device object. I think the symbolic link was deleted and it
crashed after it was trying to delete the device as I can't see the
symbolic link in the Global. How do I delete this device now. It also
gives me a error popup(system cannot find the file specified
Device\Mydriver) when I try to open the listed Mydriver under devices from
Winobj.
I tried starting the driver's service again. I do get a handle back when
opening the service. But it wont start now. giving the error value of
Cannot find the file specified. I was working fine, i mean starting the
driver before this crash.
I am a beginner with drivers and doing this to learn, please guide.

Setting input value with javascript nullifies PHP post
Setting input value with javascript nullifies PHP post
I have PHP form where I collect a bunch of values from text inputs, but
for one input I have the input filled in via javascript (user selects a
date from a calendar, that date then populates a text input). The way the
form basically works (radically simplified) is this:
<?php
$email = $_POST['email'];
?>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<input type="text" id="email" name="email" value="<?php echo
$_POST['email']; ?>" />
</form>
And then in jQuery or pure JS I do one of these:
$('#email').val('newValue');
or
document.getElementById('newValue').value = 'newValue';
Both of the above seem to work. They populate the input with the value I
want. But when I submit the form, the PHP variable that's supposed to
collect that value is null. Every other input in the form works, and if I
remove the javascript and manually enter the exact same text that I had
set with JavaScript into the input it works as well.
Any idea what's going on here? I've spent hours puzzling over this to no
avail.

Call an override method in an abstract class
Call an override method in an abstract class
i have a problem. I try to start the override Host method from Program.cs

I add here all sample classes i create for showing what i mean. The line
with ((AbstractGenericClass) Activator.CreateInstance(typeof(T))).Host();
crash the program because of InvalidCastException. It must be possible to
call the Host method but i have no idea how i could this, if this dont
operates.
Have you any other idea how this could operate? Or is this totally wrong
what i try?

sqlite or mysql for symfony2 CMF
sqlite or mysql for symfony2 CMF
I was installing the symfony2 CMF using composer and I noticed that the
default PDO handler for it is set to sqlite. I'm just curious if there's
any reason behind it that related to performance or the symfony team just
don't feel like using mysql for CMF.

Replace result from awk
Replace result from awk
Basically, what I want to do is replacing a result parsed from awk with
something else. I have the following awk command :
awk '$1~/^DocumentRoot/{print $2}' /etc/apache2/sites-available/default
Which returns :
/var/www/
What I want to do is replace the /var/www/ (of course, it can be anything
and not /var/www/ in particular) in the file. I tried to pipe a sed
command, but I can't figure out how to do it...
Anyone can help ?

It might be problem due to inner join? Actually I want data on the basis
of limit but how I dont know?

Can google datastore manage lots of continous write operations?
Can google datastore manage lots of continous write operations?
I'm using google app engine to read data from a google cloud sql database
and write some of its data and some derived data in google datastore, the
database right now doesn't have lots of entries per day, but it's
estimated to have around 200-300 entries per day on the future. I'm
testing to write all the data from the whole databse that now has a number
aproximately equal to these entries in it doesn't work properly, first of
all not all entries are being taken and derived data is sometimes properly
written and other times not, the result changes everytime I do a reading
from the database, so I guess that at least partially google datastore has
something that is related to the problem.
Don't know if google datastore could fall into race conditions or
something like that, although it would be sort of strange, but I'd like to
know if someone has had problems similar to mine and if how he was able to
solve it if he could.
Thanks.

Fetch user plotted latitude and longitude on Google Maps
Fetch user plotted latitude and longitude on Google Maps
I've a map displayed to the user, and he/she has the ability to plot on
the map his/her location and the google map marker appears, now how do I
fetch programatically the location plotted by the user on the google map.
I will be using this data and storing it in my database, which I can
handle on my own, but I'm unsure of how to fetch the data plotted by the
user.
Someone has already implemented it or has a link or tutorials to it,
please share.
Thanks

MySQL Order By alternate values
MySQL Order By alternate values
Im having trouble in MySQL query Order By.
First I have a table(tbl_records) that contains 10000+ records. This table
has a primary key called rec_id and a foreign key rec_f_id.
rec_f_id has only two kinds of value (555, 666).
Now my problem is how can I gather the records on the table that orders in
alternate value of rec_f_id.
Eg
SELECT * FROM tbl_records ORDER BY FIELD(rec_f_id, 555, 666) LIMIT 100;
The above query only returns record with rec_f_id = 555. What I want to
have is
| rec_id | rec_f_id |
|1 |555 |
|2 |666 |
|3 |555 |
|4 |666 |
|5 |555 |
|6 |666 |
|7 |555 |
|8 |666 |
|9 |555 |

How to perfectly combine Scrum and Kanban
How to perfectly combine Scrum and Kanban
I understand the philosophies of both Scrum and Kanban. I've seen some
articles saying they can be combined together to achieve better efficiency
than using only one of them. Can someone share some experience of running
a scrum team by combining Scrum and Kanban together? Any thoughts are
appreciated.

stop R process without closing console?
stop R process without closing console?
I've accidentally initiated a long process in R without saving what I need
from the workspace I'm using in the R console. I would like to stop the
current process without closing the console. But, what always happens in
an intensive process is that the R Console will not respond. I will then
either have to wait or exit out of the console. I am running 64 bit R
2.15.0 and my OS is Windows & 64-bit. Is there some way to kill R
processes outside the R environment and not close the console?

Comparing Multiple Items
Comparing Multiple Items
I apologize for my ignorance, but I've gone through stackoverflow array
element comparison topics, but none of them really have what I need.
I'm programming in java.
My problem is that I need to compare multiple items in an ArrayList,
however I can't seem to figure out how to draw images where the ArrayItem
is.
Like I have an Item in arraylist with an x and y, and in my main activity
class, I try to do
g.getImage(picturename, ArrayItem.x, ArrayItem.y, this);
It asks me to change the items x and y to static.
If someone could point me in the correct way, thanks.

How to get total possible result set from a pagination type query?
How to get total possible result set from a pagination type query?
I'm using SQLLite in AS3 AIR, and am paginating like in the following
example query (100 results per page):
SELECT * FROM table1 WHERE col1 LIKE "%my keywords here%" LIMIT 100 OFFSET 0
It works fine - I change the offset when the user hits a next or previous
button. So the next button's subsequent query is:
SELECT * FROM table1 WHERE col1 LIKE "%my keywords here%" LIMIT 100 OFFSET
100
Just wondering if it's possible to get the total number of possible
results, so I can dsiplay 'page 3 of 12' etc? Or do I have to do two
queries - the first a count(*) without the LIMIT and OFFSET so I get the
result total, and then the above query to get the actual page result?
Thanks for your time and help.

Condtional check: If anyone of the value in this array is false I will be
showing an error message else if everything is true I will be showing
success message.
var boolIteration = iArray.split(',');
var i;
for (i = 0; i < boolIteration.length; ++i) {
//conditional check
}
I'm struggling to iterate the array using the above condition.
Can anyone point me in the right direction with an efficient solution.
I have framed an array like below
iArray = [true, true, false, false, false, false, false, false, true,
true, true, false,
true, false, false, false, false, true]
Condtional check: If anyone of the value in this array is false I will be
showing an error message else if everything is true I will be showing
success message.
var boolIteration = iArray.split(',');
var i;
for (i = 0; i < boolIteration.length; ++i) {
