Hi this is due to new version of the jQuery => 1.9.0
you can check the update : http://blog.jquery.com/2013/01/15/jquery-1-9-final-jquery-2-0-beta-migrate-final-released/
jQuery.Browser is deprecated. you can keep latest version by adding a migration script : http://code.jquery.com/jquery-migrate-1.0.0.js
replace :
<script src="http://code.jquery.com/jquery-latest.js"></script>
by :
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.0.0.js"></script>
in your page and its working.
The solution is very simple, but took me about 2 hours and half the hair on my head to find it.
Simply wrap your content with a (redundant) div
that has display: none
and Bob is your uncle.
<div style="display: none">
<div id="content-div">Some content here</div>
</div>
Voila
You could use:
$('#btnForm').click(function(){
$.fancybox({
'content' : $("#divForm").html()
});
};
As it turns out, autoplay cannot be done on iOS devices (iPhone, iPad, iPod touch) and Android.
See https://stackoverflow.com/a/8142187/2054512 and https://stackoverflow.com/a/3056220/2054512
According to http://fancybox.net/faq
- How can I close FancyBox from other element? ?
Just call
$.fn.fancybox.close()
on your onClick event
So you should just be able to add in the fn
.
$("a.more").click(function() {
$.fancybox({
'padding' : 0,
'autoScale' : false,
'transitionIn' : 'none',
'transitionOut' : 'none',
'title' : this.title,
'width' : 680,
'height' : 495,
'href' : this.href.replace(new RegExp("watch\\?v=", "i"), 'v/'),
'type' : 'swf', // <--add a comma here
'swf' : {'allowfullscreen':'true'} // <-- flashvars here
});
return false;
});
function myfunction(){
$('.classname').fancybox().trigger('click');
}
It works for me..
Fancybox 2.x at least has an "overlay helper" which turned out to be the key for me. I added the following to my fancybox configuration parameters:
helpers : {
overlay : {
css : { 'overlay' : 'hidden' }
}
}
I had tried setting this in the CSS, but that didn't work, and late in the game, such as on the beforeShow event, but that led to a flickering bar. This seems to work without a hitch.
Greybox cannot handle forms inside it on its own. It requires a forms plugin. No iframes or external html files needed. Don't forget to download the greybox.css file too as the page misses that bit out.
Kiss Jquery UI goodbye and a lightbox hello. You can get it here.
I got this to work by calling this function in document ready:
$(document).ready(function () {
$.fancybox({
'width': '40%',
'height': '40%',
'autoScale': true,
'transitionIn': 'fade',
'transitionOut': 'fade',
'type': 'iframe',
'href': 'http://www.example.com'
});
});
var formatter = new Intl.NumberFormat("ru", {
style: "currency",
currency: "GBP"
});
alert( formatter.format(1234.5) ); // 1 234,5 £

This way is good and conventional:

Late to the party but for anyone who wants to make 2 borders (on the bottom and right in my case) you can use the technique in the accepted answer and add an :after psuedo-element for the second line then just change the properties like so: http://jsfiddle.net/oeaL9fsm/
div
{
width:500px;
height:500px;
position: relative;
z-index : 1;
}
div:before {
content : "";
position: absolute;
left : 25%;
bottom : 0;
height : 1px;
width : 50%;
border-bottom:1px solid magenta;
}
div:after {
content : "";
position: absolute;
right : 0;
bottom : 25%;
height : 50%;
width : 1px;
border-right:1px solid magenta;
}
Assuming your m_Queue
contains integers:
std::queue<int>().swap(m_Queue)
Otherwise, if it contains e.g. pointers to Job
objects, then:
std::queue<Job*>().swap(m_Queue)
This way you swap an empty queue with your m_Queue
, thus m_Queue
becomes empty.
Starting with the mobile version first, you can achieve what you want, most of the time.

A workaround to consider in a pinch:
The data in the database will have the quotes once the import is done... you can update the data later on to remove the quotes, or use the "replace" function in your read query, such as "replace([dbo].[MyTable].[MyColumn], '''', '')"
Here a CSS animation fork of jezzipin's Solution, to seperate code from styling.
JS:
$(window).on("scroll touchmove", function () {
$('#header_nav').toggleClass('tiny', $(document).scrollTop() > 0);
});
CSS:
.header {
width:100%;
height:100px;
background: #26b;
color: #fff;
position:fixed;
top:0;
left:0;
transition: height 500ms, background 500ms;
}
.header.tiny {
height:40px;
background: #aaa;
}
http://jsfiddle.net/sinky/S8Fnq/
On scroll/touchmove the css class "tiny" is set to "#header_nav" if "$(document).scrollTop()" is greater than 0.
CSS transition attribute animates the "height" and "background" attribute nicely.
Want to add a difference:
Trying to acess a inexistent key gives runtime error in Dictionary but no problem in hashtable as it returns null instead of error.
e.g.
//No strict type declaration
Hashtable hash = new Hashtable();
hash.Add(1, "One");
hash.Add(2, "Two");
hash.Add(3, "Three");
hash.Add(4, "Four");
hash.Add(5, "Five");
hash.Add(6, "Six");
hash.Add(7, "Seven");
hash.Add(8, "Eight");
hash.Add(9, "Nine");
hash.Add("Ten", 10);// No error as no strict type
for(int i=0;i<=hash.Count;i++)//=>No error for index 0
{
//Can be accessed through indexers
Console.WriteLine(hash[i]);
}
Console.WriteLine(hash["Ten"]);//=> No error in Has Table
here no error for key 0 & also for key "ten"(note: t is small)
//Strict type declaration
Dictionary<int,string> dictionary= new Dictionary<int, string>();
dictionary.Add(1, "One");
dictionary.Add(2, "Two");
dictionary.Add(3, "Three");
dictionary.Add(4, "Four");
dictionary.Add(5, "Five");
dictionary.Add(6, "Six");
dictionary.Add(7, "Seven");
dictionary.Add(8, "Eight");
dictionary.Add(9, "Nine");
//dictionary.Add("Ten", 10);// error as only key, value pair of type int, string can be added
//for i=0, key doesn't exist error
for (int i = 1; i <= dictionary.Count; i++)
{
//Can be accessed through indexers
Console.WriteLine(dictionary[i]);
}
//Error : The given key was not present in the dictionary.
//Console.WriteLine(dictionary[10]);
here error for key 0 & also for key 10 as both are inexistent in dictionary, runtime error, while try to acess.
Socket connections in Android are the same as in Java: http://www.oracle.com/technetwork/java/socket-140484.html
Things you need to be aware of:
Take a look at AlarmManager
, if you need scheduled execution of your code.
Do you need to run your code and receive data even if user does not use the app any more (i.e. app is inactive)?
For example if there is employee table which consists of columns as:
employee_number,f_name,l_name,email_id,phone_number
if we want to concatenate f_name + l_name
as name
.
SELECT employee_number,f_name ::TEXT ||','|| l_name::TEXT AS "NAME",email_id,phone_number,designation FROM EMPLOYEE;
These messages are rather misleading and understandably a source of confusion. Older Ubuntu versions used Libav which is a fork of the FFmpeg project. FFmpeg returned in Ubuntu 15.04 "Vivid Vervet".
The fork was basically a non-amicable result of conflicting personalities and development styles within the FFmpeg community. It is worth noting that the maintainer for Debian/Ubuntu switched from FFmpeg to Libav on his own accord due to being involved with the Libav fork.
ffmpeg
vs the fake oneFor a while both Libav and FFmpeg separately developed their own version of ffmpeg
.
Libav then renamed their bizarro ffmpeg
to avconv
to distance themselves from the FFmpeg project. During the transition period the "not developed anymore" message was displayed to tell users to start using avconv
instead of their counterfeit version of ffmpeg
. This confused users into thinking that FFmpeg (the project) is dead, which is not true. A bad choice of words, but I can't imagine Libav not expecting such a response by general users.
This message was removed upstream when the fake "ffmpeg
" was finally removed from the Libav source, but, depending on your version, it can still show up in Ubuntu because the Libav source Ubuntu uses is from the ffmpeg-to-avconv transition period.
In June 2012, the message was re-worded for the package libav - 4:0.8.3-0ubuntu0.12.04.1
. Unfortunately the new "deprecated" message has caused additional user confusion.
Starting with Ubuntu 15.04 "Vivid Vervet", FFmpeg's ffmpeg
is back in the repositories again.
To further complicate matters, Libav chose a name that was historically used by FFmpeg to refer to its libraries (libavcodec, libavformat, etc). For example the libav-user mailing list, for questions and discussions about using the FFmpeg libraries, is unrelated to the Libav project.
If you are using avconv
then you are using Libav. If you are using ffmpeg
you could be using FFmpeg or Libav. Refer to the first line in the console output to tell the difference: the copyright notice will either mention FFmpeg or Libav.
Secondly, the version numbering schemes differ. Each of the FFmpeg or Libav libraries contains a version.h
header which shows a version number. FFmpeg will end in three digits, such as 57.67.100, and Libav will end in one digit such as 57.67.0. You can also view the library version numbers by running ffmpeg
or avconv
and viewing the console output.
ffmpeg
The real ffmpeg
is in the repository, so you can install it with:
apt-get install ffmpeg
Your options are:
ffmpeg
,ffmpeg
,These methods are non-intrusive, reversible, and will not interfere with the system or any repository packages.
Another possible option is to upgrade to Ubuntu 15.04 "Vivid Vervet" or newer and just use ffmpeg
from the repository.
For an interesting blog article on the situation, as well as a discussion about the main technical differences between the projects, see The FFmpeg/Libav situation.
The only easy way to do this is to use snprintf
to print to a buffer that's long enough to hold the entire, exact value, then truncate it as a string. Something like:
char buf[2*(DBL_MANT_DIG + DBL_MAX_EXP)];
snprintf(buf, sizeof buf, "%.*f", (int)sizeof buf, x);
char *p = strchr(buf, '.'); // beware locale-specific radix char, though!
p[2+1] = 0;
puts(buf);
This is the default working setup https://www.youtube.com/watch?v=XiD7JTCBdpI
Use Connection Method: standard TCP/IP over ssh
Then ssh hostname: 127.0.0.1:2222
SSH Username: vagrant password vagrant

I want to share the one I am using:
import time
# provide a waiting-time list:
lst = [1,2,7,4,5,6,4,3]
# set the timeout limit
timeLimit = 4
for i in lst:
timeCheck = time.time()
while True:
time.sleep(i)
if time.time() <= timeCheck + timeLimit:
print ([i,'looks ok'])
break
else:
print ([i,'too long'])
break
Then you will get:
[1, 'looks ok']
[2, 'looks ok']
[7, 'too long']
[4, 'looks ok']
[5, 'too long']
[6, 'too long']
[4, 'looks ok']
[3, 'looks ok']
There are two differences:
We can use Iterator to traverse Set and List and also Map type of Objects. While a ListIterator can be used to traverse for List-type Objects, but not for Set-type of Objects.
That is, we can get a Iterator object by using Set and List, see here:
By using Iterator we can retrieve the elements from Collection Object in forward direction only.
Methods in Iterator:
hasNext()
next()
remove()
Iterator iterator = Set.iterator();
Iterator iterator = List.iterator();
But we get ListIterator object only from the List interface, see here:
where as a ListIterator allows you to traverse in either directions (Both forward and backward). So it has two more methods like hasPrevious()
and previous()
other than those of Iterator. Also, we can get indexes of the next or previous elements (using nextIndex()
and previousIndex()
respectively )
Methods in ListIterator:
ListIterator listiterator = List.listIterator();
i.e., we can't get ListIterator object from Set interface.
Reference : - What is the difference between Iterator and ListIterator ?
Define your own parse format string to use.
string formatString = "yyyyMMddHHmmss";
string sample = "20100611221912";
DateTime dt = DateTime.ParseExact(sample,formatString,null);
In case you got a datetime having milliseconds, use the following formatString
string format = "yyyyMMddHHmmssfff"
string dateTime = "20140123205803252";
DateTime.ParseExact(dateTime ,format,CultureInfo.InvariantCulture);

There is a way to make youtube autoplay, and complete playlists play through. Get Adblock browser for Android, and then go to the youtube website, and and configure it for the desktop version of the page, close Adblock browser out, and then reopen, and you will have the desktop version, where autoplay will work.
Using the desktop version will also mean that AdBlock will work. The mobile version invokes the standalone YouTube player, which is why you want the desktop version of the page, so that autoplay will work, and so ad blocking will work.
I'm not sure whether you think about:
select * from friend f
where not exists (
select 1 from likes l where f.id1 = l.id and f.id2 = l.id2
)
it works only if id1 is related with id1 and id2 with id2 not both.
All you need is the following snippet inside pom.xml's build/plugins
:
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
The above will run in the package
phase when you run
mvn clean package
And the dependencies will be copied to the outputDirectory specified in the snippet, i.e. lib
in this case.
If you only want to do that occasionally, then no changes to pom.xml are required. Simply run the following:
mvn clean package dependency:copy-dependencies
To override the default location, which is ${project.build.directory}/dependencies
, add a System property named outputDirectory
, i.e.
-DoutputDirectory=${project.build.directory}/lib
date -j -f "%Y-%m-%d" "2010-10-02" "+%s"
>>> a= [1, 2, 3, 4, 5, 1, 2, 3, 4, 5, 1]
>>> for n, i in enumerate(a):
... if i == 1:
... a[n] = 10
...
>>> a
[10, 2, 3, 4, 5, 10, 2, 3, 4, 5, 10]
OK, singleton could be good or evil, I know. This is my implementation, and I simply extend a classic approach to introduce a cache inside and produce many instances of a different type or, many instances of same type, but with different arguments.
I called it Singleton_group, because it groups similar instances together and prevent that an object of the same class, with same arguments, could be created:
# Peppelinux's cached singleton
class Singleton_group(object):
__instances_args_dict = {}
def __new__(cls, *args, **kwargs):
if not cls.__instances_args_dict.get((cls.__name__, args, str(kwargs))):
cls.__instances_args_dict[(cls.__name__, args, str(kwargs))] = super(Singleton_group, cls).__new__(cls, *args, **kwargs)
return cls.__instances_args_dict.get((cls.__name__, args, str(kwargs)))
# It's a dummy real world use example:
class test(Singleton_group):
def __init__(self, salute):
self.salute = salute
a = test('bye')
b = test('hi')
c = test('bye')
d = test('hi')
e = test('goodbye')
f = test('goodbye')
id(a)
3070148780L
id(b)
3070148908L
id(c)
3070148780L
b == d
True
b._Singleton_group__instances_args_dict
{('test', ('bye',), '{}'): <__main__.test object at 0xb6fec0ac>,
('test', ('goodbye',), '{}'): <__main__.test object at 0xb6fec32c>,
('test', ('hi',), '{}'): <__main__.test object at 0xb6fec12c>}
Every object carries the singleton cache... This could be evil, but it works great for some :)

I found the syslog module to make it quite easy to get the basic logging behavior you describe:
import syslog
syslog.syslog("This is a test message")
syslog.syslog(syslog.LOG_INFO, "Test message at INFO priority")
There are other things you could do, too, but even just the first two lines of that will get you what you've asked for as I understand it.
This solution worked for me:
<body onload="setTimeout(function() { document.myform.submit() }, 5000)">
<form action=TripRecorder name="myform">
<textarea id="result1" name="res1" value="str1" cols="20" rows="1" ></textarea> <br> <br/>
<textarea id="result2" name="res2" value="str2" cols="20" rows="1" ></textarea>
</form>
</body>
As mentioned in other answers, test.only
merely filters out other tests in the same file. So tests in other files would still run.
So to run a single test, there are two approaches:
Option 1: If your test name is unique, you can enter t
while in watch mode and enter the name of the test you'd like to run.
Option 2:
p
while in watch mode to enter a regex for the filename you'd like to run. (Relevant commands like this are displayed when you run Jest in watch mode).it
to it.only
on the test you'd like to run.With either of the approaches above, Jest will only run the single test in the file you've specified.
Ok, here's a simple box that follows the cursor
Doing the rest is a simple case of remembering the last cursor position and applying a formula to get the box to move other than exactly where the cursor is. A timeout would also be handy if the box has a limited acceleration and must catch up to the cursor after it stops moving. Replacing the box with an image is simple CSS (which can replace most of the setup code for the box). I think the actual thinking code in the example is about 8 lines.
Select the right image (use a sprite) to orientate the rocket.

I'd just like to point out something in these answers. In a date/time format string, '/' will be replaced with whatever the user's date separator is, and ':' will be replaced with whatever the user's time separator is. That is, if I've defined my date separator to be '.' (in the Regional and Language Options control panel applet, "intl.cpl"), and my time separator to be '?' (just pretend I'm crazy like that), then
DateTime.Now.ToString("MM/dd/yyyy h:mm tt")
would return
01.05.2009 6?01 PM
In most cases, this is what you want, because you want to respect the user's settings. If, however, you require the format be something specific (say, if it's going to parsed back out by somebody else down the wire), then you need to escape these special characters:
DateTime.Now.ToString("MM\\/dd\\/yyyy h\\:mm tt")
or
DateTime.Now.ToString(@"MM\/dd\/yyyy h\:mm tt")
which would now return
01/05/2009 6:01 PM
EDIT:
Then again, if you really want to respect the user's settings, you should use one of the standard date/time format strings, so that you respect not only the user's choices of separators, but also the general format of the date and/or time.
DateTime.Now.ToShortDateString()
DateTime.Now.ToString("d")
Both would return "1/5/2009" using standard US options, or "05/01/2009" using standard UK options, for instance.
DateTime.Now.ToLongDateString()
DateTime.Now.ToString("D")
Both would return "Monday, January 05, 2009" in US locale, or "05 January 2009" in UK.
DateTime.Now.ToShortTimeString()
DateTime.Now.ToString("t");
"6:01 PM" in US, "18:01" in UK.
DateTime.Now.ToLongTimeString()
DateTime.Now.ToString("T");
"6:01:04 PM" in US, "18:01:04" in UK.
DateTime.Now.ToString()
DateTime.Now.ToString("G");
"1/5/2009 6:01:04 PM" in US, "05/01/2009 18:01:04" in UK.
Many other options are available. See docs for standard date and time format strings and custom date and time format strings.
- First to me Iterating
and Looping
are 2 different things.
Eg: Increment a variable till 5 is Looping.
int count = 0;
for (int i=0 ; i<5 ; i++){
count = count + 1;
}
Eg: Iterate over the Array to print out its values, is about Iteration
int[] arr = {5,10,15,20,25};
for (int i=0 ; i<arr.length ; i++){
System.out.println(arr[i]);
}
Now about all the Loops:
- Its always better to use For-Loop when you know the exact nos of time you gonna Loop, and if you are not sure of it go for While-Loop. Yes out there many geniuses can say that it can be done gracefully with both of them and i don't deny with them...but these are few things which makes me execute my program flawlessly...
For Loop
:
int sum = 0;
for (int i = 1; i <= 100; i++) {
sum += i;
}
System.out.println("The sum is " + sum);
The Difference between While and Do-While is as Follows :
- While
is a Entry Control Loop
, Condition is checked in the Beginning before entering the loop.
- Do-While
is a Exit Control Loop
, Atleast once the block is always executed then the Condition is checked.
While Loop
:
int sum = 0;
int i = 0; // i is 0 Here
while (i<100) {
sum += i;
i++;
}
System.out.println("The sum is " + sum);
do-While
:
int sum = 0;
int i = 0; // i is 0 Here
do{
sum += i;
i++
}while(i < 100; );
System.out.println("The sum is " + sum);
From Java 5 we also have For-Each Loop to iterate over the Collections, even its handy with Arrays.
ArrayList<String> arr = new ArrayList<String>();
arr.add("Vivek");
arr.add("Is");
arr.add("Good");
arr.add("Boy");
for (String str : arr){ // str represents the value in each index of arr
System.out.println(str);
}
Strictly speaking, you should put something that makes sense - according to the spec here, the most correct version is:
<input name=name id=id type=checkbox checked=checked>
For HTML, you can also use the empty attribute syntax, checked=""
, or even simply checked
(for stricter XHTML, this is not supported).
Effectively, however, most browsers will support just about any value between the quotes. All of the following will be checked:
<input name=name id=id type=checkbox checked>
<input name=name id=id type=checkbox checked="">
<input name=name id=id type=checkbox checked="yes">
<input name=name id=id type=checkbox checked="blue">
<input name=name id=id type=checkbox checked="false">
And only the following will be unchecked:
<input name=name id=id type=checkbox>
See also this similar question on disabled="disabled"
.
This isn't necessarily exhaustive.
options = {...optionsDefault, ...options};
If authoring code for execution in environments without native support, you may be able to just compile this syntax (as opposed to using a polyfill). (With Babel, for example.)
Less verbose.
When this answer was originally written, this was a proposal, not standardized. When using proposals consider what you'd do if you write code with it now and it doesn't get standardized or changes as it moves toward standardization. This has since been standardized in ES2018.
Literal, not dynamic.
Object.assign()
options = Object.assign({}, optionsDefault, options);
Standardized.
Dynamic. Example:
var sources = [{a: "A"}, {b: "B"}, {c: "C"}];
options = Object.assign.apply(Object, [{}].concat(sources));
// or
options = Object.assign({}, ...sources);
This is the commit that made me wonder.
That's not directly related to what you're asking. That code wasn't using Object.assign()
, it was using user code (object-assign
) that does the same thing. They appear to be compiling that code with Babel (and bundling it with Webpack), which is what I was talking about: the syntax you can just compile. They apparently preferred that to having to include object-assign
as a dependency that would go into their build.
In addition to what Andrew said, it is worth noting that:
The distinction between a language, a runtime, and a library is more strict in .NET/C# than for example in C++, where the language specification also includes some basic library functions. The C# specification says only a very little about the environment (basically, that it should contain some types such as int
, but that's more or less all).
I was searching how to do something similar in WPF and I got this solution:
<ItemsControl ItemsSource="{Binding MyItems,Mode=OneWay}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Vertical" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<RadioButton
Content="{Binding}"
Command="{Binding Path=DataContext.CustomCommand,
RelativeSource={RelativeSource Mode=FindAncestor,
AncestorType={x:Type ItemsControl}} }"
CommandParameter="{Binding}" />
</DataTemplate>
</ItemsControl.ItemTemplate>
I hope this works for somebody else. I have a data context which is set automatically to the ItemsControls, and this data context has two properties: MyItems
-which is a collection-, and one command 'CustomCommand'. Because of the ItemTemplate
is using a DataTemplate
, the DataContext
of upper levels is not directly accessible. Then the workaround to get the DC of the parent is use a relative path and filter by ItemsControl
type.
If you're looking for short answer:
In the case of using java.util.Date, Java doesn't really know how to directly relate to SQL types. This is when @Temporal
comes into play. It's used to specify the desired SQL type.

Another approach, if you're desperate and don't have access to (a) the code or (b) the command line, then you can use environment variables:
http://docs.oracle.com/javase/7/docs/webnotes/tsg/TSG-Desktop/html/plugin.html.
Specifically for java web start set the environment variable:
JAVAWS_VM_ARGS
and for applets:
_JPI_VM_OPTIONS
e.g.
_JPI_VM_OPTIONS=-Djava.net.preferIPv4Stack=true
Additionally, under Windows global options (for general Java applications) can be set in the Java control plan page under the "Java" tab.
You just need to have your class inherit from Comparable.
then implement the compareTo method the way you like.
This is the correct answer. It worked!!

A cast, as Blaz Bratanic suggested:
size_t data = 99999999;
int convertdata = static_cast<int>(data);
is likely to silence the warning (though in principle a compiler can warn about anything it likes, even if there's a cast).
But it doesn't solve the problem that the warning was telling you about, namely that a conversion from size_t
to int
really could overflow.
If at all possible, design your program so you don't need to convert a size_t
value to int
. Just store it in a size_t
variable (as you've already done) and use that.
Converting to double
will not cause an overflow, but it could result in a loss of precision for a very large size_t
value. Again, it doesn't make a lot of sense to convert a size_t
to a double
; you're still better off keeping the value in a size_t
variable.
(R Sahu's answer has some suggestions if you can't avoid the cast, such as throwing an exception on overflow.)
just use the -d option of the date command, e.g.
date -d '20121212' +'%Y %m'
To find a very long list of words in big files, it can be more efficient to use egrep:
remove the last \n of A
$ tr '\n' '|' < A > A_regex
$ egrep -f A_regex B
I had a similar issue so I found a workaround (remove hyperlink tags thanks to regular expressions so that only a paragraph tag remains). I posted this solution on https://github.com/python-openxml/python-docx/issues/85 BP
That should work. I am not sure why it's failing. You're quoting your variables properly. What happens if you use this script with double [[
]]
?
if [[ -d $PASSED ]]; then
echo "$PASSED is a directory"
elif [[ -f $PASSED ]]; then
echo "$PASSED is a file"
else
echo "$PASSED is not valid"
exit 1
fi
Double square brackets is a bash extension to [ ]
. It doesn't require variables to be quoted, not even if they contain spaces.
Also worth trying: -e
to test if a path exists without testing what type of file it is.
You can use LIMIT 2,1
instead of WHERE row_number() = 3
.
As the documentation explains, the first argument specifies the offset of the first row to return, and the second specifies the maximum number of rows to return.
Keep in mind that it's an 0-based index. So, if you want the line number n, the first argument should be n-1. The second argument will always be 1, because you just want one row. For example, if you want the line number 56 of a table customer
:
SELECT * FROM customer LIMIT 55,1

If the use case is storing data in a collection then ECMAScript 6 provides the Map
type.
It's only heavier to initialize.
Here is an example:
const map = new Map();
map.set(1, "One");
map.set(2, "Two");
map.set(3, "Three");
console.log("=== With Map ===");
for (const [key, value] of map) {
console.log(`${key}: ${value} (${typeof(key)})`);
}
console.log("=== With Object ===");
const fakeMap = {
1: "One",
2: "Two",
3: "Three"
};
for (const key in fakeMap) {
console.log(`${key}: ${fakeMap[key]} (${typeof(key)})`);
}
Result:
=== With Map ===
1: One (number)
2: Two (number)
3: Three (number)
=== With Object ===
1: One (string)
2: Two (string)
3: Three (string)

I read all the clunky solutions on the net about how to mask passwords in a batch file, the ones from using a hide.com solution and even the ones that make the text and the background the same color. The hide.com solution works decent, it isn't very secure, and it doesn't work in 64-bit Windows. So anyway, using 100% Microsoft utilities, there is a way!
First, let me explain my use. I have about 20 workstations that auto logon to Windows. They have one shortcut on their desktop - to a clinical application. The machines are locked down, they can't right click, they can't do anything but access the one shortcut on their desktop. Sometimes it is necessary for a technician to kick up some debug applications, browse windows explorer and look at log files without logging the autolog user account off.
So here is what I have done.
Do it however you wish, but I put my two batch files on a network share that the locked down computer has access to.
My solution utilizes 1 main component of Windows - runas. Put a shortcut on the clients to the runas.bat you are about to create. FYI, on my clients I renamed the shortcut for better viewing purposes and changed the icon.
You will need to create two batch files.
I named the batch files runas.bat and Debug Support.bat
runas.bat contains the following code:
cls
@echo off
TITLE CHECK CREDENTIALS
goto menu
:menu
cls
echo.
echo ....................................
echo ~Written by Cajun Wonder 4/1/2010~
echo ....................................
echo.
@set /p un=What is your domain username?
if "%un%"=="PUT-YOUR-DOMAIN-USERNAME-HERE" goto debugsupport
if not "%un%"=="PUT-YOUR-DOMAIN-USERNAME-HERE" goto noaccess
echo.
:debugsupport
"%SYSTEMROOT%\system32\runas" /netonly /user:PUT-YOUR-DOMAIN-NAME-HERE\%un% "\\PUT-YOUR-NETWORK-SHARE-PATH-HERE\Debug Support.bat"
@echo ACCESS GRANTED! LAUNCHING THE DEBUG UTILITIES....
@ping -n 4 127.0.0.1 > NUL
goto quit
:noaccess
cls
@echo.
@echo.
@echo.
@echo.
@echo \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
@echo \\ \\
@echo \\ Insufficient privileges \\
@echo \\ \\
@echo \\ Call Cajun Wonder \\
@echo \\ \\
@echo \\ At \\
@echo \\ \\
@echo \\ 555-555-5555 \\
@echo \\ \\
@echo \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
@ping -n 4 127.0.0.1 > NUL
goto quit
@pause
:quit
@exit
You can add as many if "%un%" and if not "%un%" for all the users you want to give access to. The @ping is my coonass way of making a seconds timer.
So that takes care of the first batch file - pretty simple eh?
Here is the code for Debug Support.bat:
cls
@echo off
TITLE SUPPORT UTILITIES
goto menu
:menu
cls
@echo %username%
echo.
echo .....................................
echo ~Written by Cajun Wonder 4/1/2010~
echo .....................................
echo.
echo What do you want to do?
echo.
echo [1] Launch notepad
echo.
:choice
set /P C=[Option]?
if "%C%"=="1" goto notepad
goto choice
:notepad
echo.
@echo starting notepad....
@ping -n 3 127.0.0.1 > NUL
start notepad
cls
goto menu
I'm not a coder and really just started getting into batch scripting about a year ago, and this round about way that I discovered of masking a password in a batch file is pretty awesome!
I hope to hear that someone other than me is able to get some use out of it!
If you want to create dynamically/runtime data table in VB.Net then you should follow these steps as mentioned below :
For eg.
Dim dt As New DataTable
dt.Columns.Add("Id", GetType(Integer))
dt.Columns.Add("FirstName", GetType(String))
dt.Columns.Add("LastName", GetType(String))
dt.Rows.Add(1, "Test", "data")
dt.Rows.Add(15, "Robert", "Wich")
dt.Rows.Add(18, "Merry", "Cylon")
dt.Rows.Add(30, "Tim", "Burst")
If you have control over the structure of the list, the most pythonic thing to do would probably be to change it from:
l=[1,2,3,4]
to:
l=[(1,2),(3,4)]
Then, your loop would be:
for i,j in l:
print i, j
Ref: https://garbagevalue.com/blog/4-simle-ways-to-check-ip-adress-in-centos-7
I'm using CentOS 7 and command
ip a
is enough to do the job.
Just slice out the IP address part from that test.
ip a | grep 192
I opened this thread looking for a quick solution to a simple question, but I found that the answers here were either not helpful or overly complicated. The best way to get the last 5 chars of a string is, in fact, to use the Right() method. Here is a simple example:
Dim sMyString, sLast5 As String
sMyString = "I will be going to school in 2011!"
sLast5 = Right(sMyString, - 5)
MsgBox("sLast5 = " & sLast5)
If you're getting an error then there is probably something wrong with your syntax. Also, with the Right() method you don't need to worry much about going over or under the string length. In my example you could type in 10000 instead of 5 and it would just MsgBox the whole string, or if sMyString was NULL or "", the message box would just pop up with nothing.
new Integer(i).toString();
This statement creates the object of the Integer and then call its methods toString(i)
to return the String representation of Integer's value.
Integer.toString(i);
It returns the String object representing the specific int (integer), but here toString(int)
is a static
method.
Summary is in first case it returns the objects string representation, where as in second case it returns the string representation of integer.
Another good trick is to go into UTF8 mode in your editor so that you can actually see these funny characters and delete them yourself.
I think your issue may be in the url pattern. Changing
<servlet-mapping>
<servlet-name>Register</servlet-name>
<url-pattern>/Register</url-pattern>
</servlet-mapping>
and
<form action="/Register" method="post">
may fix your problem

You can use the extension method AsEnumerable in Assembly System.Core and System.Linq namespace :
List<Book> list = new List<Book>();
return list.AsEnumerable();
This will, as said on this MSDN link change the type of the List in compile-time. This will give you the benefits also to only enumerate your collection we needed (see MSDN example for this).
Check out my answer in this similar question:
python: urllib2 how to send cookie with urlopen request
import urllib2
import urllib
from cookielib import CookieJar
cj = CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
# input-type values from the html form
formdata = { "username" : username, "password": password, "form-id" : "1234" }
data_encoded = urllib.urlencode(formdata)
response = opener.open("https://page.com/login.php", data_encoded)
content = response.read()
EDIT:
I see I've gotten a few downvotes for my answer, but no explaining comments. I'm guessing it's because I'm referring to the urllib
libraries instead of requests
. I do that because the OP asks for help with requests
or for someone to suggest another approach.
For checkbox with an id
<input id="id_input_checkbox13" type="checkbox"></input>
you can simply do
$("#id_input_checkbox13").prop('checked')
you will get true
or false
as return value for above syntax. You can use it in if clause as normal boolean expression.
The Bitwise complement operator(~) is a unary operator.
It works as per the following methods
First it converts the given decimal number to its corresponding binary value.That is in case of 2 it first convert 2 to 0000 0010 (to 8 bit binary number).
Then it converts all the 1 in the number to 0,and all the zeros to 1;then the number will become 1111 1101.
that is the 2's complement representation of -3.
In order to find the unsigned value using complement,i.e. simply to convert 1111 1101 to decimal (=4294967293) we can simply use the %u during printing.
I would recommend separating out all of the foreign-key constraints from your CREATE TABLE
statements. Create all the tables first without FK constraints, and then create all the FK constraints once you have created the tables.
You can add an FK constraint to a table using SQL like the following:
ALTER TABLE orders ADD CONSTRAINT orders_FK
FOREIGN KEY (m_p_unique_id) REFERENCES library (m_p_unique_id);
In particular, your formats
and library
tables both have foreign-key constraints on one another. The two CREATE TABLE
statements to create these two tables can never run successfully, as each will only work when the other table has already been created.
Separating out the constraint creation allows you to create tables with FK constraints on one another. Also, if you have an error with a constraint, only that constraint fails to be created. At present, because you have errors in the constraints in your CREATE TABLE
statements, then entire table creation fails and you get various knock-on errors because FK constraints may depend on these tables that failed to create.
A better solution would be to make an Ajax call inside the iframe to the page that would get/set cookies...
You can also try BootFlat, which has a section in their documentation specifically for crafting Timelines:
It could also be that your anaconda
version is 32 bit
when it should be 64 bit

The title of your question is:
How to join a slice of strings into a single string?
but in fact, reg
is not a slice, but a length-three array. [...]string
is just syntactic sugar for (in this case) [3]string
.
To get an actual slice, you should write:
reg := []string {"a","b","c"}
(Try it out: https://play.golang.org/p/vqU5VtDilJ.)
Incidentally, if you ever really do need to join an array of strings into a single string, you can get a slice from the array by adding [:]
, like so:
fmt.Println(strings.Join(reg[:], ","))
(Try it out: https://play.golang.org/p/zy8KyC8OTuJ.)
You've already got it: A if test else B
is a valid Python expression. The only problem with your dict comprehension as shown is that the place for an expression in a dict comprehension must have two expressions, separated by a colon:
{ (some_key if condition else default_key):(something_if_true if condition
else something_if_false) for key, value in dict_.items() }
The final if
clause acts as a filter, which is different from having the conditional expression.
Could not get this to work until I put Authorization in single quotes:
axios.get(URL, { headers: { 'Authorization': AuthStr } })
NOTE: I concocted this solution before I was reminded about all the "special cases" that can occur in a valid CSV file, like escaped quotes. I'm leaving my answer for those who want something quick and dirty, but I recommend Evan's answer for accuracy.
This code will work when your data.txt
file is one long string of comma-separated entries, with no newlines:
data.txt:
heading1,heading2,heading3,heading4,heading5,value1_1,...,value5_2
javascript:
$(document).ready(function() {
$.ajax({
type: "GET",
url: "data.txt",
dataType: "text",
success: function(data) {processData(data);}
});
});
function processData(allText) {
var record_num = 5; // or however many elements there are in each row
var allTextLines = allText.split(/\r\n|\n/);
var entries = allTextLines[0].split(',');
var lines = [];
var headings = entries.splice(0,record_num);
while (entries.length>0) {
var tarr = [];
for (var j=0; j<record_num; j++) {
tarr.push(headings[j]+":"+entries.shift());
}
lines.push(tarr);
}
// alert(lines);
}
The following code will work on a "true" CSV file with linebreaks between each set of records:
data.txt:
heading1,heading2,heading3,heading4,heading5
value1_1,value2_1,value3_1,value4_1,value5_1
value1_2,value2_2,value3_2,value4_2,value5_2
javascript:
$(document).ready(function() {
$.ajax({
type: "GET",
url: "data.txt",
dataType: "text",
success: function(data) {processData(data);}
});
});
function processData(allText) {
var allTextLines = allText.split(/\r\n|\n/);
var headers = allTextLines[0].split(',');
var lines = [];
for (var i=1; i<allTextLines.length; i++) {
var data = allTextLines[i].split(',');
if (data.length == headers.length) {
var tarr = [];
for (var j=0; j<headers.length; j++) {
tarr.push(headers[j]+":"+data[j]);
}
lines.push(tarr);
}
}
// alert(lines);
}

arc4random_uniform() is recommended over constructions like arc4random() % upper_bound
as it avoids "modulo bias" when the upper bound is not a power of two.
it should be :
$_SERVER['REQUEST_URI'];

As strings are immutable in Python, just create a new string which includes the value at the desired index.
Assuming you have a string s
, perhaps s = "mystring"
You can quickly (and obviously) replace a portion at a desired index by placing it between "slices" of the original.
s = s[:index] + newstring + s[index + 1:]
You can find the middle by dividing your string length by 2 len(s)/2
If you're getting mystery inputs, you should take care to handle indices outside the expected range
def replacer(s, newstring, index, nofail=False):
# raise an error if index is outside of the string
if not nofail and index not in range(len(s)):
raise ValueError("index outside given string")
# if not erroring, but the index is still not in the correct range..
if index < 0: # add it to the beginning
return newstring + s
if index > len(s): # add it to the end
return s + newstring
# insert the new string between "slices" of the original
return s[:index] + newstring + s[index + 1:]
This will work as
replacer("mystring", "12", 4)
'myst12ing'

It's 2020 - nobody should be using Net::HTTP
any more and all answers seem to be saying so, use a more high level gem such as Faraday - Github
That said, what I like to do is a wrapper around the HTTP api call,something that's called like
rv = Transporter::FaradayHttp[url, options]
because this allows me to fake HTTP calls without additional dependencies, ie:
if InfoSig.env?(:test) && !(url.to_s =~ /localhost/)
response_body = FakerForTests[url: url, options: options]
else
conn = Faraday::Connection.new url, connection_options
Where the faker looks something like this
I know there are HTTP mocking/stubbing frameworks, but at least when I researched last time they didn't allow me to validate requests efficiently and they were just for HTTP, not for example for raw TCP exchanges, this system allows me to have a unified framework for all API communication.
Assuming you just want to quick&dirty convert a hash to json, send the json to a remote host to test an API and parse response to ruby this is probably fastest way without involving additional gems:
JSON.load `curl -H 'Content-Type:application/json' -H 'Accept:application/json' -X POST localhost:3000/simple_api -d '#{message.to_json}'`
Hopefully this goes without saying, but don't use this in production.
Seems like you posted a new question after you realized that you were dealing with a simpler problem related to size_t
. I am glad that you did.
Anyways, You have a .c
source file, and most of the code looks as per C standards, except that #include <iostream>
and using namespace std;
C equivalent for the built-in functions of C++ standard #include<iostream>
can be availed through #include<stdio.h>
#include <iostream>
with #include <stdio.h>
, delete using namespace std;
With #include <iostream>
taken off, you would need a C standard alternative for cout << endl;
, which can be done by printf("\n");
or putchar('\n');
Out of the two options, printf("\n");
works the faster as I observed.
When used printf("\n");
in the code above in place of cout<<endl;
$ time ./thread.exe

You can use "<pre>(.*?)</pre>"

As other commenters have suggested, if you're doing something complex, use a HTML parser.

DB2 has several strategies to cope with this problem.
You can use the "scrollable cursor" in feature.
In this case you can open a cursor and, instead of re-issuing a query you can FETCH forward and backward.
This works great if your application can hold state since it doesn't require DB2 to rerun the query every time.
You can use the ROW_NUMBER() OLAP function to number rows and then return the subset you want.
This is ANSI SQL
You can use the ROWNUM pseudo columns which does the same as ROW_NUMBER() but is suitable if you have Oracle skills.
You can use LIMIT and OFFSET if you are more leaning to a mySQL or PostgreSQL dialect.
Since I have recently developed an Android application using gyroscope data (steady compass), I tried to collect a list with such devices. This is not an exhaustive list at all, but it is what I have so far:
*** Phones:
*** Tablets:
Hope the list keeps growing and hope that gyros will be soon available on mid and low price smartphones.
As Pax said, you probably aren't going to get any faster than this. The reason is that there are almost no filesystems that support truncating from the beginning of the file so this is going to be an O(n
) operation where n
is the size of the file. What you can do much faster though is overwrite the first line with the same number of bytes (maybe with spaces or a comment) which might work for you depending on exactly what you are trying to do (what is that by the way?).
Chris pretty much sums up what w3wp is. In order to disable the warning, go to this registry key:
HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\Debugger
And set the value DisableAttachSecurityWarning
to 1.
WordPress
If you work in the wordpress environment, Wordpress sets the error level in file wp-includes/load.php in function wp_debug_mode()
. So you have to change the level AFTER this function has been called ( in a file not checked into git so that's development only ), or either modify directly the error_reporting()
call
Do you mean that for a select element with an id of "next" you need to perform some specific script?
$("#next").change(function(){
//enter code here
});
In Python 3, I find pathlib is the easiest way to do this. Request's response.content marries up nicely with pathlib's write_bytes.
from pathlib import Path
import requests
filename = Path('metadata.pdf')
url = 'http://www.hrecos.org//images/Data/forweb/HRTVBSH.Metadata.pdf'
response = requests.get(url)
filename.write_bytes(response.content)
You can't do it with client side script only... you could make an AJAX call to some server side code that will send an email...
('.cat').hover(
function () {
$(this).show();
},
function () {
$(this).hide();
}
);
It's the same for the others.

Make the table with an integer timestamp:
mysql> create table foo(id INT, mytimestamp INT(11));
Query OK, 0 rows affected (0.02 sec)
Insert some values
mysql> insert into foo values(1, 1381262848);
Query OK, 1 row affected (0.01 sec)
Take a look
mysql> select * from foo;
+------+-------------+
| id | mytimestamp |
+------+-------------+
| 1 | 1381262848 |
+------+-------------+
1 row in set (0.00 sec)
Convert the number to a timestamp:
mysql> select id, from_unixtime(mytimestamp) from foo;
+------+----------------------------+
| id | from_unixtime(mytimestamp) |
+------+----------------------------+
| 1 | 2013-10-08 16:07:28 |
+------+----------------------------+
1 row in set (0.00 sec)
Convert it into a readable format:
mysql> select id, from_unixtime(mytimestamp, '%Y %D %M %H:%i:%s') from foo;
+------+-------------------------------------------------+
| id | from_unixtime(mytimestamp, '%Y %D %M %H:%i:%s') |

Without a bit of information about what files are in your repository (pure source code, images, executables, ...), it's a bit hard to answer the question :)
Beside this, I'll consider that you're willing to default to LF as line endings in your working directory because you're willing to make sure that text files have LF line endings in your .git repository wether you work on Windows or Linux. Indeed better safe than sorry....
However, there's a better alternative: Benefit from LF line endings in your Linux workdir, CRLF line endings in your Windows workdir AND LF line endings in your repository.
As you're partially working on Linux and Windows, make sure core.eol
is set to native
and core.autocrlf
is set to true
.
Then, replace the content of your .gitattributes
file with the following
* text=auto
This will let Git handle the automagic line endings conversion for you, on commits and checkouts. Binary files won't be altered, files detected as being text files will see the line endings converted on the fly.
However, as you know the content of your repository, you may give Git a hand and help him detect text files from binary files.
Provided you work on a C based image processing project, replace the content of your .gitattributes
file with the following
* text=auto
*.txt text
*.c text
*.h text
*.jpg binary
This will make sure files which extension is c, h, or txt will be stored with LF line endings in your repo and will have native line endings in the working directory. Jpeg files won't be touched. All of the others will be benefit from the same automagic filtering as seen above.
In order to get a get a deeper understanding of the inner details of all this, I'd suggest you to dive into this very good post "Mind the end of your line" from Tim Clem, a Githubber.
As a real world example, you can also peek at this commit where those changes to a .gitattributes
file are demonstrated.
UPDATE to the answer considering the following comment
I actually don't want CRLF in my Windows directories, because my Linux environment is actually a VirtualBox sharing the Windows directory
Makes sense. Thanks for the clarification. In this specific context, the .gitattributes
file by itself won't be enough.
Run the following commands against your repository
$ git config core.eol lf
$ git config core.autocrlf input
As your repository is shared between your Linux and Windows environment, this will update the local config file for both environment. core.eol
will make sure text files bear LF line endings on checkouts. core.autocrlf
will ensure potential CRLF in text files (resulting from a copy/paste operation for instance) will be converted to LF in your repository.
Optionally, you can help Git distinguish what is a text file by creating a .gitattributes
file containing something similar to the following:
# Autodetect text files
* text=auto
# ...Unless the name matches the following
# overriding patterns
# Definitively text files
*.txt text
*.c text
*.h text
# Ensure those won't be messed up with
*.jpg binary
*.data binary
If you decided to create a .gitattributes
file, commit it.
Lastly, ensure git status
mentions "nothing to commit (working directory clean)", then perform the following operation
$ git checkout-index --force --all
This will recreate your files in your working directory, taking into account your config changes and the .gitattributes
file and replacing any potential overlooked CRLF in your text files.
Once this is done, every text file in your working directory WILL bear LF line endings and git status
should still consider the workdir as clean.
There's no way to do this with any built-in functions, because it would be terribly inefficient. You'd need to shift the existing contents of the file down each time you add a line at the front.
There's a Unix/Linux utility tail
which can read from the end of a file. Perhaps you can find that useful in your application.
This did the trick for me when I couldn't get the style spacing to work from the span tag:
<p style='margin-bottom: 5px' >

A cleaner Python3 version that use standard numpy, matplotlib and PIL. Merging the answer for opening from URL.
import matplotlib.pyplot as plt
from PIL import Image
import numpy as np
pil_im = Image.open('image.png') #Take jpg + png
## Uncomment to open from URL
#import requests
#r = requests.get('https://www.vegvesen.no/public/webkamera/kamera?id=131206')
#pil_im = Image.open(BytesIO(r.content))
im_array = np.asarray(pil_im)
plt.imshow(im_array)
plt.show()
I had this error in tests, the directive templateUrl
wasn't trusted, but only for the spec, so I added the template directory:
beforeEach(angular.mock.module('app.templates'));
My main directory is app
.
Try
$(bla).click(function(){
if (something) {
console.log("A:"+$target.prev("input")) // gives out the right object
$target.toggleClass("open").prev("input").attr("disabled", "disabled");
}else{
console.log("A:"+$target.prev("input")) // any thing from there for a single click?
$target.toggleClass("open").prev("input").removeAttr("disabled"); //this works
}
});
Be careful, when you register by
LocalBroadcastManager.getInstance(this).registerReceiver()
you can't unregister by
unregisterReceiver()
you must use
LocalBroadcastManager.getInstance(this).unregisterReceiver()
or app will crash, log as follow:

There are three ways
1) This runs the GUI editor for the user environment variables. It does exactly what the OP wanted to do and does not prompt for administrative credentials.
rundll32.exe sysdm.cpl,EditEnvironmentVariables
(bonus: This works on Windows Vista to Windows 10 for desktops and Windows Server 2008 through Server 2016. It does not work on Windows NT, 2000, XP, and 2003. However, on the older systems you can use sysdm.cpl without the ",EditEnvironmentVariables" parameter and then navigate to the Advanced tab and then Environment Variables button.)
2) Use the SETX command from the command prompt. This is like the set command but updates the environment that's stored in the registry. Unfortunately, SETX is not as easy to use as the built in SET command. There's no way to list the variables for example. Thus it's impossible to do something such as appending a folder to the user's PATH variable. While SET will display the variables you don't know which ones are user vs. system variables and the PATH that's shown is a combination of both.
3) Use regedit and navigate to HKEY_CURRENT_USER\Environment
Keep in mind that changes to the user's environment does not immediately propagate to all processes currently running for that user. You can see this in a command prompt where your changes will not be visible if you use SET. For example
rem Add a user environment variable named stackoverflow that's set to "test"
setx stackoverflow test
set st
This should show all variables whose names start with the letters "st". If there are none then it displays "Environment variable st not defined
".
Exit the command prompt and start another. Try set st
again
and you'll see
stackoverflow=test
To delete the stackoverflow variable use
setx stackoverflow ""
It will respond with "SUCCESS: Specified value was saved.
" which looks strange given you want to delete the variable. However, if you start a new command prompt then set st
will show that there are no variables starting with the letters "st"
(correction - I discovered that setx stackoverflow ""
did not delete the variable. It's in the registry as an empty string. The SET
command though interprets it as though there is no variable. if not defined stackoverflow echo Not defined
says it's not defined.)
add a reference to this
, which refers to your b_row
:
$("tr.b_row").each(function(){
var a_href = $( this ).find('div.cpt h2 a').attr('href');
alert ("Href is: "+a_href);
});
I had a similar issue and was able to resolve it by identifying which JDBC driver I intended to use. In my case, I was connecting to an Oracle database. I placed the following statement, prior to creating the connection variable.
DriverManager.registerDriver( new oracle.jdbc.driver.OracleDriver());
Other way to solve the problem of space reclaiming is, Create multiple partitions within table - Range based, Value based partitions and just drop/truncate the partition to reclaim the space, which will release the space used by whole data stored in the particular partition.
There will be some changes needed in table schema when you introduce the partitioning for your table like - Unique Keys, Indexes to include partition column etc.
Here's an alternate solution, without using dblink
.
Suppose B represents the source database and A represents the target database: Then,
Copy table from source DB to target DB:
pg_dump -t <source_table> <source_db> | psql <target_db>
Open psql prompt, connect to target_db, and use a simple insert
:
psql
# \c <target_db>;
# INSERT INTO <target_table>(id, x, y) SELECT id, x, y FROM <source_table>;
At the end, delete the copy of source_table that you created in target_table.
# DROP TABLE <source_table>;
Yet another trick (as of v1.6)
A=np.arange(1,10).reshape(3,3)
b=np.arange(3)
np.einsum('ij,i->ij',A,b)
I'm proficient with the numpy broadcasting (newaxis
), but I'm still finding my way around this new einsum
tool. So I had play around a bit to find this solution.
Timings (using Ipython timeit):
einsum: 4.9 micro
transpose: 8.1 micro
newaxis: 8.35 micro
dot-diag: 10.5 micro
Incidentally, changing a i
to j
, np.einsum('ij,j->ij',A,b)
, produces the matrix that Alex does not want. And np.einsum('ji,j->ji',A,b)
does, in effect, the double transpose.
<?php
foreach ($_POST as $key => $value) {
echo '<p>'.$key.'</p>';
foreach($value as $k => $v)
{
echo '<p>'.$k.'</p>';
echo '<p>'.$v.'</p>';
echo '<hr />';
}
}
?>
this will work, your first solution is trying to print array, because your value is an array.
Try this
ALTER TABLE `table_name` CHANGE `column_name` `column_name` data_type NULL DEFAULT '';
like this
ALTER TABLE `drivers_meta` CHANGE `driving_license` `driving_license` VARCHAR(30) NULL DEFAULT '';
Ansible supports patterns which can be used for one/multiple hosts,groups and also can exclude/include groups. Here is the link for official document.

I thought that I might add this snippet to this old post. This is what I had done in the past, before the icons were fonts:
<i class="social-icon linkedin small" style="border-radius:7.5px;height:15px;width:15px;background-color:white;></i>
<i class="social-icon facebook small" style="border-radius:7.5px;height:15px;width:15px;background-color:white;></i>
This is very similar to @frbl 's sneaky answer, yet it does not use another image. Instead, this sets the background-color of the <i>
element to white
and uses the CSS property border-radius
to make the entire <i>
element "rounded." If you noticed, the value of the border-radius
(7.5px) is exactly half that of the width
and height
property (both 15px, making the icon square), making the <i>
element circular.
One thing not mentioned in answers is inline element can break among lines while inline-block can't (and obviously block)! So inline elements can be useful to style sentences of text and blocks inside them, but as they can't be padded you can use line-height instead.

When you have a lot of variables that don't need escaping, you can use an autoescape
block:
{% autoescape off %}
{{ something }}
{{ something_else }}
<b>{{ something_important }}</b>
{% endautoescape %}
You need to go through SimpleDateFormat.format
in order to format the date as a string.
Here's an example that goes from String
-> Date
-> String
.
SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy");
Date date = dateFormat.parse("31/05/2011");
System.out.println(dateFormat.format(date)); // prints 31/05/2011
// ^^^^^^
You should be pointing it towards the Developer
directory, not the Xcode application bundle. Run this:
sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.
The function takes two arguments:
start - the start index;
length - the length of substring to capitalise
String.prototype.subUpper = function () {
var result = this.toString();
var start = 0;
var length = 1;
if (arguments.length > 0) {
start = arguments[0];
if (start < this.length) {
if (arguments.length > 1) {
length = arguments[1];
}
if (start + length > this.length) {
length = this.length - start;
}
var startRest = start + length;
var prefix = start > 0 ? this.substr(0, start) : String.empty;
var sub = this.substr(start, length);
var suffix = this.substr(startRest, this.length - startRest);
result = prefix + sub.toUpperCase() + suffix;
}
}
return result;
};
The first argument should be the path to the executable program. So
gdb progname 12271
set -x
Prints a trace of simple commands, for commands, case commands, select commands, and arithmetic for commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4 variable is expanded and the resultant value is printed before the command and its expanded arguments.

set -x
echo `expr 10 + 20 `
+ expr 10 + 20
+ echo 30
30
set +x
echo `expr 10 + 20 `
30
Above example illustrates the usage of set -x
. When it is used, above arithmetic expression has been expanded. We could see how a singe line has been evaluated step by step.

The easiest and the most straightforward way:
To activate: File > Settings > Editor > General
For Mac OS X
, Android Studio > Preferences > Editor > General and check Show quick documentation on mouse move:
Other ways:
You can go into your IntelliJ's bin folder and search for idea.properties. Add this line to the document:
auto.show.quick.doc=true
Now you'll have the same floating docs window like in Eclipse.
You have to press CTRL+Q to see the Javadoc.
You can pin the window and make the documentation appear every time you select a method with your mouse though.
Android Studio 1.0: You have to hold CTRL if you want to get hold of documentation window for e.g. scrolling documentation otherwise as you move your mouse away from method documentation window will disappear.
You can do it programatically:
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
public class ActivityName extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// remove title
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
}
}
Or you can do it via your AndroidManifest.xml
file:
<activity android:name=".ActivityName"
android:label="@string/app_name"
android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">
</activity>
Edit: I added some lines so that you can show it in fullscreen, as it seems that's what you want.

Explanation of both of these functions from here.
Generally the reason why the "instanceof" operator is frowned upon in a case like that (where the instanceof is checking for subclasses of this base class) is because what you should be doing is moving the operations into a method and overridding it for the appropriate subclasses. For instance, if you have:
if (o instanceof Class1)
doThis();
else if (o instanceof Class2)
doThat();
//...
You can replace that with
o.doEverything();
and then have the implementation of "doEverything()" in Class1 call "doThis()", and in Class2 call "doThat()", and so on.
A compiler may place structure members on particular byte boundaries for reasons of performance on a particular architecture. This may leave unused padding between members. Structure packing forces members to be contiguous.
This may be important for example if you require a structure to conform to a particular file or communications format where the data you need the data to be at specific positions within a sequence. However such usage does not deal with endian-ness issues, so although used, it may not be portable.
It may also to exactly overlay the internal register structure of some I/O device such as a UART or USB controller for example, in order that register access be through a structure rather than direct addresses.
As you can see in the Java Source of the java.lang.String class:
/**
* Allocates a new <code>String</code> that contains characters from
* a subarray of the character array argument. The <code>offset</code>
* argument is the index of the first character of the subarray and
* the <code>count</code> argument specifies the length of the
* subarray. The contents of the subarray are copied; subsequent
* modification of the character array does not affect the newly
* created string.
*
* @param value array that is the source of characters.
* @param offset the initial offset.
* @param count the length.
* @exception IndexOutOfBoundsException if the <code>offset</code>
* and <code>count</code> arguments index characters outside
* the bounds of the <code>value</code> array.
*/
public String(char value[], int offset, int count) {
if (offset < 0) {
throw new StringIndexOutOfBoundsException(offset);
}
if (count < 0) {
throw new StringIndexOutOfBoundsException(count);
}
// Note: offset or count might be near -1>>>1.
if (offset > value.length - count) {
throw new StringIndexOutOfBoundsException(offset + count);
}
this.value = new char[count];
this.count = count;
System.arraycopy(value, offset, this.value, 0, count);
}
Parameter references are surrounded by <code></code>
tags, which means that the Javadoc syntax does not provide any way to do such a thing. (I think String.class is a good example of javadoc usage).
Gson is very usefull for this. easier even. here is my example:
public class Bean {
private String nombre="juan";
private String apellido="machado";
private List<InnerBean> datosCriticos;
class InnerBean
{
private int edad=12;
}
public Bean() {
datosCriticos = new ArrayList<>();
datosCriticos.add(new InnerBean());
}
}
Bean bean = new Bean();
Gson gson = new Gson();
String json =gson.toJson(bean);
out.print(json);
{"nombre":"juan","apellido":"machado","datosCriticos":[{"edad":12}]}
Have to say people if yours vars are empty when using gson it wont build the json for you.Just the
{}
In almost any language this should work instead:
a = true && 5 || 10
a = false && 5 || 10
Microsoft Core Library, ie they are at the heart of everything.
There is a more "massaged" explanation you may prefer:
"When Microsoft first started working on the .NET Framework, MSCorLib.dll was an acronym for Microsoft Common Object Runtime Library. Once ECMA started to standardize the CLR and parts of the FCL, MSCorLib.dll officially became the acronym for Multilanguage Standard Common Object Runtime Library."
From http://weblogs.asp.net/mreynolds/archive/2004/01/31/65551.aspx
Around 1999, to my personal memory, .Net was known as "COOL", so I am a little suspicious of this derivation. I never heard it called "COR", which is a silly-sounding name to a native English speaker.
For Fedora (tested for Fedora 23/24) run

If I may suggest a safer approach:
Declare a buffer big enough to hold the string:
char user_input[255];
Get the user input in a safe way:
fgets(user_input, 255, stdin);
A safe way to get the input, the first argument being a pointer to a buffer where the input will be stored, the second the maximum input the function should read and the third is a pointer to the standard input - i.e. where the user input comes from.
Safety in particular comes from the second argument limiting how much will be read which prevents buffer overruns. Also, fgets
takes care of null-terminating the processed string.
More info on that function here.
EDIT: If you need to do any formatting (e.g. convert a string to a number), you can use atoi once you have the input.
You could do something like this:
Convert.ToDate(month + " 01, 1900").Month
It's required for extensibility -- if someone uses an API you've developed, the enums you define are static; they can't be added to or modified. However, if you let it implement an interface, the person using the API can develop their own enum using the same interface. You can then register this enum with an enum manager which conglomerates the enums together with the standard interface.
Edit: @Helper Method has the perfect example of this. Think about having other libraries defining new operators and then telling a manager class that 'hey, this enum exists -- register it'. Otherwise, you'd only be able to define Operators in your own code - there'd be no extensibility.
If you intend to use the times later to compute with, learn how to use the -f
option of /usr/bin/time
to output code that saves times. Here's some code I used recently to get and sort the execution times of a whole classful of students' programs:
fmt="run { date = '$(date)', user = '$who', test = '$test', host = '$(hostname)', times = { user = %U, system = %S, elapsed = %e } }"
/usr/bin/time -f "$fmt" -o $timefile command args...
I later concatenated all the $timefile
files and pipe the output into a Lua interpreter. You can do the same with Python or bash or whatever your favorite syntax is. I love this technique.
Write the following method:
public boolean isAlertPresent() {
try {
driver.switchTo().alert();
return true;
} // try
catch (Exception e) {
return false;
} // catch
}
Now, you can check whether alert is present or not by using the method written above as below:
if (isAlertPresent()) {
driver.switchTo().alert();
driver.switchTo().alert().accept();
driver.switchTo().defaultContent();
}
If somebody is looking for solution respecting holidays (without any huge library like pandas), try this function:
import holidays
import datetime
def previous_working_day(check_day_, holidays=holidays.US()):
offset = max(1, (check_day_.weekday() + 6) % 7 - 3)
most_recent = check_day_ - datetime.timedelta(offset)
if most_recent not in holidays:
return most_recent
else:
return previous_working_day(most_recent, holidays)
check_day = datetime.date(2020, 12, 28)
previous_working_day(check_day)
which produce:
datetime.date(2020, 12, 24)
Resize image with high quality:
private static InputStream resizeImage(InputStream uploadedInputStream, String fileName, int width, int height) {
try {
BufferedImage image = ImageIO.read(uploadedInputStream);
Image originalImage= image.getScaledInstance(width, height, Image.SCALE_DEFAULT);
int type = ((image.getType() == 0) ? BufferedImage.TYPE_INT_ARGB : image.getType());
BufferedImage resizedImage = new BufferedImage(width, height, type);
Graphics2D g2d = resizedImage.createGraphics();
g2d.drawImage(originalImage, 0, 0, width, height, null);
g2d.dispose();
g2d.setComposite(AlphaComposite.Src);
g2d.setRenderingHint(RenderingHints.KEY_INTERPOLATION,RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g2d.setRenderingHint(RenderingHints.KEY_RENDERING,RenderingHints.VALUE_RENDER_QUALITY);
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
ImageIO.write(resizedImage, fileName.split("\\.")[1], byteArrayOutputStream);
return new ByteArrayInputStream(byteArrayOutputStream.toByteArray());
} catch (IOException e) {
// Something is going wrong while resizing image
return uploadedInputStream;
}
}
This answer focusses more on the sidenote "i.e. has at least one alphanumeric character". Besides that, it doesn't add too much to the other (earlier) solution, except that it doesn't hurt you with NPE in case the String is null
.
We want false
if (1) s is null
or (2) s is empty or (3) s only contains whitechars.
public static boolean containsNonWhitespaceChar(String s) {
return !((s == null) || "".equals(s.trim()));
}
I don't think this is allowed by most browsers for security reasons, in a pure JavaScript context as the question asks.
You could add dataformatstring="{0:M-dd-yyyy}
" attribute to the bound field, like this:
<asp:BoundField DataField="Date" HeaderText="Date" DataFormatString="{0:dd-M-yyyy}" />
If you need one ore more fixed-width columns while other columns should resize, try setting both min-width
and max-width
to the same value.
a = [1,1,1,1,2,2,2,2,3,3,4,5,5]
# 1. Get counts and store in another list
output = []
for i in set(a):
output.append(a.count(i))
print(output)
# 2. Remove duplicates using set constructor
a = list(set(a))
print(a)
Output
D:\MLrec\venv\Scripts\python.exe D:/MLrec/listgroup.py
[4, 4, 2, 1, 2]
[1, 2, 3, 4, 5]
Its not exactly elegant, but if you use List.listIterator(int index) you can get a bi-directional ListIterator to the end of the list:
//Assume List<String> foo;
ListIterator li = foo.listIterator(foo.size());
while (li.hasPrevious()) {
String curr = li.previous()
}
Actually it is possible in JPA, although a little bit of a hack using the columnDefinition
property of the @Column
annotation, for example:
@Column(name="Price", columnDefinition="Decimal(10,2) default '100.00'")
For iTunes 12, drag the .ipa file from the Finder to the Apps area NOT inside your device (in iTunes)... alternately, you can just double click on the .ipa in the Finder.
Important note: you have to change Version and/or Build number. Otherwise, you get no notice from iTunes at all...
Then switch to your device in iTunes, and install or update the application.
Then hit sync.
For gcc 4.8.4
you need to use -std=c++1y
in later versions, looks like starting with 5.2
you can use -std=c++14
.
If we look at the gcc online documents we can find the manuals for each version of gcc and we can see by going to Dialect options for 4.9.3 under the GCC 4.9.3 manual it says:
‘c++1y’
The next revision of the ISO C++ standard, tentatively planned for 2014. Support is highly experimental, and will almost certainly change in incompatible ways in future releases.
So up till 4.9.3
you had to use -std=c++1y
while the gcc 5.2 options say:
‘c++14’ ‘c++1y’
The 2014 ISO C++ standard plus amendments. The name ‘c++1y’ is deprecated.
It is not clear to me why this is listed under Options Controlling C Dialect
but that is how the documents are currently organized.

if lims is None:
lims = ax.get_xlim()
y_points = np.repeat(ys[:, None], repeats=3, axis=1).flatten()
x_points = np.repeat(np.array(lims + (np.nan, ))[None, :], repeats=len(ys), axis=0).flatten()

I had the same problem, getting the message "ImportError: No module named numpy".
I'm also using anaconda and found out that I needed to add numpy to the ENV I was using. You can check the packages you have in your environment with the command:
conda list
So, when I used that command, numpy was not displayed. If that is your case, you just have to add it, with the command:
conda install numpy
After I did that, the error with the import numpy
was gone
There is a list option in Data validation. If this is combined with a VLOOKUP formula you would be able to convert the selected value into a number.
The steps in Excel 2010 are:
In a cell enter a formula like this
=VLOOKUP(A2,$D$3:$E$5,2,FALSE)
which will return the matching value from the second part of your list.
Alternatively, Form controls can be placed on a worksheet. They can be linked to a range and return the position number of the selected value to a specific cell.
The steps in Excel 2010 are:
If you are using Sql Server Management Studio, you can create your own schema by browsing to Databases - Your Database - Security - Schemas.
To create one using a script is as easy as (for example):
CREATE SCHEMA [EnterSchemaNameHere] AUTHORIZATION [dbo]
You can use them to logically group your tables, for example by creating a schema for "Financial" information and another for "Personal" data. Your tables would then display as:
Financial.BankAccounts Financial.Transactions Personal.Address
Rather than using the default schema of dbo.
If the file is small, you can read the whole data once:
File file = new File("a.txt");
FileInputStream fis = new FileInputStream(file);
byte[] data = new byte[(int) file.length()];
fis.read(data);
fis.close();
String str = new String(data, "UTF-8");
Try the Content-Disposition
header
Content-Disposition: attachment; filename=<file name.ext>
This is a hack to make inner functions (functions defined inside other functions) work more like they should. In javascript when you define one function inside another this
automatically gets set to the global scope. This can be confusing because you expect this
to have the same value as in the outer function.
var car = {};
car.starter = {};
car.start = function(){
var that = this;
// you can access car.starter inside this method with 'this'
this.starter.active = false;
var activateStarter = function(){
// 'this' now points to the global scope
// 'this.starter' is undefined, so we use 'that' instead.
that.starter.active = true;
// you could also use car.starter, but using 'that' gives
// us more consistency and flexibility
};
activateStarter();
};
This is specifically a problem when you create a function as a method of an object (like car.start
in the example) then create a function inside that method (like activateStarter
). In the top level method this
points to the object it is a method of (in this case, car
) but in the inner function this
now points to the global scope. This is a pain.
Creating a variable to use by convention in both scopes is a solution for this very general problem with javascript (though it's useful in jquery functions, too). This is why the very general sounding name that
is used. It's an easily recognizable convention for overcoming a shortcoming in the language.
Like El Ronnoco hints at Douglas Crockford thinks this is a good idea.
You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like
$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");
You can confirm this by printing out the string to see that it turns out identical to the first case.
Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string
, which would make it look perhaps like this:
$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
mysql_real_escape_string($prefix));
$query = mysql_query($sql);
Note that inside the first argument of sprintf
the percent sign needs to be doubled to end up appearing once in the result.
Let's understand in simple words
Note: These keys have more depth as a concept but this is good to start.
If it´s in the global scope it´s better to use:
function foo()
{
alert('foo');
}
var a = 'foo';
window[a]();
than eval()
. Because eval()
is evaaaaaal.

1) How to access Model data in Javascript/Jquery code block in
.cshtml
file2) How to access Model data in Javascript/Jquery code block in
.js
file
.cshtml
fileThere are two types of c# variable (Model
) assignments to JavaScript variable.
int
, string
, DateTime
(ex: Model.Name
)Model
, Model.UserSettingsObj
)Lets look into the details of these two assignments.
For the rest of the answer lets consider the below AppUser
Model as an example.
public class AppUser
{
public string Name { get; set; }
public bool IsAuthenticated { get; set; }
public DateTime LoginDateTime { get; set; }
public int Age { get; set; }
public string UserIconHTML { get; set; }
}
And the values we assign this Model are
AppUser appUser = new AppUser
{
Name = "Raj",
IsAuthenticated = true,
LoginDateTime = DateTime.Now,
Age = 26,
UserIconHTML = "<i class='fa fa-users'></i>"
};
Lets use different syntax for assignment and observe the results.
1) Without wrapping property assignment in quotes.
var Name = @Model.Name;
var Age = @Model.Age;
var LoginTime = @Model.LoginDateTime;
var IsAuthenticated = @Model.IsAuthenticated;
var IconHtml = @Model.UserIconHTML;
As you can see there are couple of errors, Raj
and True
is considered to be javascript variables and since they dont exist its an variable undefined
error. Where as for the dateTime varialble the error is unexpected number
numbers cannot have special characters, The HTML tags are converted into its entity names so that the browser doesn't mix up your values and the HTML markup.
2) Wrapping property assignment in Quotes.
var Name = '@Model.Name';
var Age = '@Model.Age';
var LoginTime = '@Model.LoginDateTime';
var IsAuthenticated = '@Model.IsAuthenticated';
var IconHtml = '@Model.UserIconHTML';
The results are valid, So wrapping the property assignment in quotes gives us valid syntax. But note that the Number Age
is now a string, So if you dont want that we can just remove the quotes and it will be rendered as a number type.
3) Using @Html.Raw
but without wrapping it in quotes
var Name = @Html.Raw(Model.Name);
var Age = @Html.Raw(Model.Age);
var LoginTime = @Html.Raw(Model.LoginDateTime);
var IsAuthenticated = @Html.Raw(Model.IsAuthenticated);
var IconHtml = @Html.Raw(Model.UserIconHTML);
The results are similar to our test case 1. However using @Html.Raw()
on the HTML
string did show us some change. The HTML is retained without changing to its entity names.
From the docs Html.Raw()
Wraps HTML markup in an HtmlString instance so that it is interpreted as HTML markup.
But still we have errors in other lines.
4) Using @Html.Raw
and also wrapping it within quotes
var Name ='@Html.Raw(Model.Name)';
var Age = '@Html.Raw(Model.Age)';
var LoginTime = '@Html.Raw(Model.LoginDateTime)';
var IsAuthenticated = '@Html.Raw(Model.IsAuthenticated)';
var IconHtml = '@Html.Raw(Model.UserIconHTML)';
The results are good with all types. But our HTML
data is now broken and this will break the scripts. The issue is because we are using single quotes '
to wrap the the data and even the data has single quotes.
We can overcome this issue with 2 approaches.
1) use double quotes " "
to wrap the HTML part. As the inner data has only single quotes. (Be sure that after wrapping with double quotes there are no "
within the data too)
var IconHtml = "@Html.Raw(Model.UserIconHTML)";
2) Escape the character meaning in your server side code. Like
UserIconHTML = "<i class=\"fa fa-users\"></i>"
Conclusion of property assignment
Html.Raw
to interpret your HTML data as is.Lets use different syntax for assignment and observe the results.
1) Without wrapping object assignment in quotes.
var userObj = @Model;
When you assign a c# object to javascript variable the value of the .ToString()
of that oject will be assigned. Hence the above result.
2 Wrapping object assignment in quotes
var userObj = '@Model';
3) Using Html.Raw
without quotes.
var userObj = @Html.Raw(Model);
4) Using Html.Raw
along with quotes
var userObj = '@Html.Raw(Model)';
The Html.Raw
was of no much use for us while assigning a object to variable.
5) Using Json.Encode()
without quotes
var userObj = @Json.Encode(Model);
//result is like
var userObj = {"Name":"Raj",
"IsAuthenticated":true,
"LoginDateTime":"\/Date(1482572875150)\/",
"Age":26,
"UserIconHTML":"\u003ci class=\"fa fa-users\"\u003e\u003c/i\u003e"
};
We do see some change, We see our Model is being interpreted as a object. But we have those special characters changed into entity names
. Also wrapping the above syntax in quotes is of no much use. We simply get the same result within quotes.
From the docs of Json.Encode()
Converts a data object to a string that is in the JavaScript Object Notation (JSON) format.
As you have already encountered this entity Name
issue with property assignment and if you remember we overcame it with the use of Html.Raw
. So lets try that out. Lets combine Html.Raw
and Json.Encode
6) Using Html.Raw
and Json.Encode
without quotes.
var userObj = @Html.Raw(Json.Encode(Model));
Result is a valid Javascript Object
var userObj = {"Name":"Raj",
"IsAuthenticated":true,
"LoginDateTime":"\/Date(1482573224421)\/",
"Age":26,
"UserIconHTML":"\u003ci class=\"fa fa-users\"\u003e\u003c/i\u003e"
};
7) Using Html.Raw
and Json.Encode
within quotes.
var userObj = '@Html.Raw(Json.Encode(Model))';
As you see wrapping with quotes gives us a JSON data
Conslusion on Object assignment
Html.Raw
and Json.Encode
in combintaion to assign your object to javascript variable as JavaScript object.Html.Raw
and Json.Encode
also wrap it within quotes
to get a JSONNote: If you have observed the DataTime data format is not right. This is because as said earlier Converts a data object to a string that is in the JavaScript Object Notation (JSON) format
and JSON does not contain a date
type. Other options to fix this is to add another line of code to handle this type alone using javascipt Date() object
var userObj.LoginDateTime = new Date('@Html.Raw(Model.LoginDateTime)');
//without Json.Encode
.js
fileRazor syntax has no meaning in .js
file and hence we cannot directly use our Model insisde a .js
file. However there is a workaround.
1) Solution is using javascript Global variables.
We have to assign the value to a global scoped javascipt variable and then use this variable within all code block of your .cshtml
and .js
files. So the syntax would be
<script type="text/javascript">
var userObj = @Html.Raw(Json.Encode(Model)); //For javascript object
var userJsonObj = '@Html.Raw(Json.Encode(Model))'; //For json data
</script>
With this in place we can use the variables userObj
and userJsonObj
as and when needed.
Note: I personally dont suggest using global variables as it gets very hard for maintainance. However if you have no other option then you can use it with having a proper naming convention .. something like userAppDetails_global
.
2) Using function() or closure
Wrap all the code that is dependent on the model data in a function. And then execute this function from the .cshtml
file .
external.js
function userDataDependent(userObj){
//.... related code
}
.cshtml
file
<script type="text/javascript">
userDataDependent(@Html.Raw(Json.Encode(Model))); //execute the function
</script>
Note: Your external file must be referenced prior to the above script. Else the userDataDependent
function is undefined.
Also note that the function must be in global scope too. So either solution we have to deal with global scoped players.
C# 9 (released with .NET 5) includes the logical patterns and
, or
and not
, which allows us to write this more elegantly:
if (child is not IContainer) { ... }
Likewise, this pattern can be used to check for null:
if (child is not null) { ... }
you need double quotes in all your three if
statements, eg.:
IF "%a%"=="2" (
@echo OFF &SETLOCAL ENABLEDELAYEDEXPANSION
cls
title ~USB Wizard~
echo What do you want to do?
echo 1.Enable/Disable USB Storage Devices.
echo 2.Enable/Disable Writing Data onto USB Storage.
echo 3.~Yet to come~.
set "a=%globalparam1%"
goto :aCheck
:aPrompt
set /p "a=Enter Choice: "
:aCheck
if "%a%"=="" goto :aPrompt
echo %a%
IF "%a%"=="2" (
title USB WRITE LOCK
echo What do you want to do?
echo 1.Apply USB Write Protection
echo 2.Remove USB Write Protection
::param1
set "param1=%globalparam2%"
goto :param1Check
:param1Prompt
set /p "param1=Enter Choice: "
:param1Check
if "!param1!"=="" goto :param1Prompt
if "!param1!"=="1" (
REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies\ /v WriteProtect /t REG_DWORD /d 00000001
USB Write is Locked!
)
if "!param1!"=="2" (
REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies\ /v WriteProtect /t REG_DWORD /d 00000000
USB Write is Unlocked!
)
)

This one works for me.

Even though the name is immutable, you may still want to have the option of computing it rather than storing it in a field. (I realize this is unlikely for "name", but let's aim for the general case.) For that reason, even constant fields are best wrapped inside of getters:
class Foo {
public:
const std::string& getName() const {return name_;}
private:
const std::string& name_;
};
Note that if you were to change getName()
to return a computed value, it couldn't return const ref. That's ok, because it won't require any changes to the callers (modulo recompilation.)
It should work, however http://nginx.org/en/docs/http/ngx_http_core_module.html#alias says:
When location matches the last part of the directive’s value: it is better to use the root directive instead:
which would yield:
server {
listen 8080;
server_name www.mysite.com mysite.com;
error_log /home/www-data/logs/nginx_www.error.log;
error_page 404 /404.html;
location /public/doc/ {
autoindex on;
root /home/www-data/mysite;
}
location = /404.html {
root /home/www-data/mysite/static/html;
}
}
The good practice is: Dispatch Groups
dispatch_group_t imageGroup = dispatch_group_create();
dispatch_group_enter(imageGroup);
[uploadImage executeWithCompletion:^(NSURL *result, NSError* error){
// Image successfully uploaded to S3
dispatch_group_leave(imageGroup);
}];
dispatch_group_enter(imageGroup);
[setImage executeWithCompletion:^(NSURL *result, NSError* error){
// Image url updated
dispatch_group_leave(imageGroup);
}];
dispatch_group_notify(imageGroup,dispatch_get_main_queue(),^{
// We get here when both tasks are completed
});
Open your PHPMyAdmin, don't select any database and look for Binary Log

Subclass is to Class as Java is to Programming Language.
I faced this issue with Eclipse (Version: 2019-12 (4.14.0)) too. The solution seems either to use IntelliJ or to use the Maven test to run such tests in Eclipse.
os.path.isdir() checks if the path exists and is a directory and returns TRUE for the case.
Similarly, os.path.isfile() checks if the path exists and is a file and returns TRUE for the case.
And, os.path.exists() checks if the path exists and doesn’t care if the path points to a file or a directory and returns TRUE in either of the cases.
In light of the unreadability and overcomplication of answers, i believe this is what the requestor should do
PATH
. scriptname
The .
(dot) will make sure the script is not run in a child shell.
Try this.Vals.replace(/("|')/g, "")
I find that the OS Utils from Swingx does the job.
I managed to copy text to the clipboard (without showing any text boxes) by adding a hidden input
element to body
, i.e.:
function copy(txt){_x000D_
var cb = document.getElementById("cb");_x000D_
cb.value = txt;_x000D_
cb.style.display='block';_x000D_
cb.select();_x000D_
document.execCommand('copy');_x000D_
cb.style.display='none';_x000D_
}
_x000D_
<button onclick="copy('Hello Clipboard!')"> copy </button>_x000D_
<input id="cb" type="text" hidden>
_x000D_
The jackson API has changed:
new ObjectMapper()
.writer()
.withDefaultPrettyPrinter()
.writeValueAsString(new HashMap<String, Object>());
"abcdefgh..".IndexOf("d")
returns 3
In general returns first occurrence index, if not present returns -1
I resolved the same issue using next sql and restarting MySQL server:
update mysql.user set Select_priv='Y',Insert_priv='Y',Update_priv='Y',Delete_priv='Y',Create_priv='Y',Drop_priv='Y',Reload_priv='Y',Shutdown_priv='Y',Process_priv='Y',File_priv='Y',Grant_priv='Y',References_priv='Y',Index_priv='Y',Alter_priv='Y',Show_db_priv='Y',Super_priv='Y',Create_tmp_table_priv='Y',Lock_tables_priv='Y',Execute_priv='Y',Repl_slave_priv='Y',Repl_client_priv='Y',Create_view_priv='Y',Show_view_priv='Y',Create_routine_priv='Y',Alter_routine_priv='Y',Create_user_priv='Y',Event_priv='Y',Trigger_priv='Y',Create_tablespace_priv='Y'
where user='root';
First add an Enrty
and Category
class:
public class Entry { public string Id { get; set; } public string Title { get; set; } public string Updated { get; set; } public string Summary { get; set; } public string GPoint { get; set; } public string GElev { get; set; } public List<string> Categories { get; set; } } public class Category { public string Label { get; set; } public string Term { get; set; } }
Then use LINQ to XML
XDocument xDoc = XDocument.Load("path"); List<Entry> entries = (from x in xDoc.Descendants("entry") select new Entry() { Id = (string) x.Element("id"), Title = (string)x.Element("title"), Updated = (string)x.Element("updated"), Summary = (string)x.Element("summary"), GPoint = (string)x.Element("georss:point"), GElev = (string)x.Element("georss:elev"), Categories = (from c in x.Elements("category") select new Category { Label = (string)c.Attribute("label"), Term = (string)c.Attribute("term") }).ToList(); }).ToList();

Upgrade JDK to 1.7
Make sure the 32-bit or 64 bit versions match on both sides
Elaborating on previous answer by Pir Fahim, he's right but i'm using selectedItem.Text (only way to make it work to me)
Use the SelectedIndexChanged() event to store the data somewhere. In my case, i usually fill a custom class, something like:
class myItem {
string name {get; set;}
string price {get; set;}
string desc {get; set;}
}
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
myItem selected_item = new myItem();
selected_item.name = listBox1.SelectedItem.Text;
Retrieve (selected_item.name);
}
And then you can retrieve the rest of data from a List of "myItems"..
myItem Retrieve (string wanted_item) {
foreach (myItem item in my_items_list) {
if (item.name == wanted_item) {
// This is the selected item
return item;
}
}
return null;
}
As a more systematic and structured solution you could define folders where your classes are stored and create an autoloader (__autoload()
) which will search the class files in defined places:
require_once("../settings.php");
define('DIR_CLASSES', '/path/to/the/classes/folder/'); // this can be inside your settings.php
$user = new User();
$user->createUser($_POST["username"], $_POST["email"], $_POST["password"]);
function __autoload($classname) {
if(file_exists(DIR_CLASSES . 'class' . $classname . '.php')) {
include_once(DIR_CLASSES . 'class' . $classname . '.php'); // looking for the class in the project's classes folder
} else {
include_once($classname . '.php'); // looking for the class in include_path
}
}
Here is my simple version.
The function draggable takes a jQuery object as argument.
/**
* @param {jQuery} elem
*/
function draggable(elem){
elem.mousedown(function(evt){
var x = parseInt(this.style.left || 0) - evt.pageX;
var y = parseInt(this.style.top || 0) - evt.pageY;
elem.mousemove(function(evt){
elem.css('left', x + evt.pageX);
elem.css('top', y + evt.pageY);
});
});
elem.mouseup(off);
elem.mouseleave(off);
function off(){
elem.off("mousemove");
}
}
I think, that you have to declare the associated sheet!
Try something like this
objsheet(1).Cells[i,j].Value;
I had the same exception when my code tried to set the "Accept" header value like this:
WebRequest request = WebRequest.Create("http://someServer:6405/biprws/logon/long");
request.Headers.Add("Accept", "application/json");
The solution was to change it to this:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://someServer:6405/biprws/logon/long");
request.Accept = "application/json";
If you are at a certain branch mybranch
, just go ahead and git checkout commit_hash
. Then you can return to your branch by git checkout mybranch
. I had the same game bisecting a bug today :) Also, you should know about git bisect.
you can use unique property by using len function
len(df['hID'].unique()) 5
you have to check your linked project, in the new version of RN, don't need to link if you linked it cause a problem, I Fixed the problem by unlinked manually the dependency that I linked and re-run.
byte test[] = new byte[3];
test[0] = 0x0A;
test[1] = 0xFF;
test[2] = 0x01;
for (byte theByte : test)
{
System.out.println(Integer.toHexString(theByte));
}
NOTE: test[1] = 0xFF; this wont compile, you cant put 255 (FF) into a byte, java will want to use an int.
you might be able to do...
test[1] = (byte) 0xFF;
I'd test if I was near my IDE (if I was near my IDE I wouln't be on Stackoverflow)
I have just faced the same problem. First, you need to install the appropriate Oracle client for your OS. In my case, to install it on Ubuntu x64 I have followed this instructions https://help.ubuntu.com/community/Oracle%20Instant%20Client#Install_RPMs
Then, you need to install cx_Oracle, a Python module to connect to the Oracle client. Again, assuming you are running Ubuntu in a 64bit machine, you should type in a shell:
wget -c http://prdownloads.sourceforge.net/cx-oracle/cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm
sudo alien -i cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm
This will work for Oracle 11g if you have installed Python 2.7.x, but you can download a different cx_Oracle version in http://cx-oracle.sourceforge.net/ To check which Python version do you have, type in a terminal:
python -V

In pthread_exit
, ret
is an input parameter. You are simply passing the address of a variable to the function.
In pthread_join
, ret
is an output parameter. You get back a value from the function. Such value can, for example, be set to NULL
.
Long explanation:
In pthread_join
, you get back the address passed to pthread_exit
by the finished thread. If you pass just a plain pointer, it is passed by value so you can't change where it is pointing to. To be able to change the value of the pointer passed to pthread_join, it must be passed as a pointer itself, that is, a pointer to a pointer.
Get the value of your textboxes using val()
and store them in a variable. Pass those values through $.post
. In using the $.Post Submit button
you can actually remove the form.
<script>
username = $("#username").val();
password = $("#password").val();
$("#post-btn").click(function(){
$.post("process.php", { username:username, password:password } ,function(data){
alert(data);
});
});
</script>
This one helped me:
// Add an observer that will respond to loginComplete
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(showMainMenu:)
name:@"loginComplete" object:nil];
// Post a notification to loginComplete
[[NSNotificationCenter defaultCenter] postNotificationName:@"loginComplete" object:nil];
// the function specified in the same class where we defined the addObserver
- (void)showMainMenu:(NSNotification *)note {
NSLog(@"Received Notification - Someone seems to have logged in");
}
