Just for the purpose of mentioning underscore's find method works in IE with no problem.
country.code
is not in your group by
statement, and is not an aggregate (wrapped in an aggregate function).
I had the same issue with Python3.
My code was writing into io.BytesIO()
.
Replacing with io.StringIO()
solved.
You need to do the following:
public class CountryInfoResponse {
@JsonProperty("geonames")
private List<Country> countries;
//getter - setter
}
RestTemplate restTemplate = new RestTemplate();
List<Country> countries = restTemplate.getForObject("http://api.geonames.org/countryInfoJSON?username=volodiaL",CountryInfoResponse.class).getCountries();
It would be great if you could use some kind of annotation to allow you to skip levels, but it's not yet possible (see this and this)
Implement Comparable<Animal>
interface in your class and provide implementation of int compareTo(Animal other)
method in your class.See This Post
Alternatively, when you want to save individual R objects, I recommend using saveRDS
.
You can save R objects using saveRDS
, then load them into R with a new variable name using readRDS
.
Example:
# Save the city object
saveRDS(city, "city.rds")
# ...
# Load the city object as city
city <- readRDS("city.rds")
# Or with a different name
city2 <- readRDS("city.rds")
But when you want to save many/all your objects in your workspace, use Manetheran's answer.
You can use boost::optional
(or std::optional
for newer versions), which was developed in particular for decision of your problem:
boost::optional<int> y[50];
....
geoGraph.y[x] = nums[x];
....
const size_t size_y = sizeof(y)/sizeof(y[0]); //!!!! correct size of y!!!!
for(int i=0; i<size_y;i++){
if(y[i]) { //check for null
p[i].SetPoint(Recto.Height()-x,*y[i]);
....
}
}
P.S. Do not use C-type array -> use std::array or std::vector:
std::array<int, 50> y; //not int y[50] !!!
Try something like the following:
# some sample data
idnat <- sample(c("french","foreigner"),100,TRUE)
idbp <- rep(NA,100)
idbp[idnat=="french"] <- sample(c("mainland","overseas","colony"),sum(idnat=="french"),TRUE)
# recoding
out <- ifelse(idnat=="french" & !idbp %in% c("overseas","colony"), "mainland",
ifelse(idbp %in% c("overseas","colony"),"overseas",
"foreigner"))
cbind(idnat,idbp,out) # check result
Your confusion comes from how SAS and R handle if-else constructions. In R, if
and else
are not vectorized, meaning they check whether a single condition is true (i.e., if("french"=="french")
works) and cannot handle multiple logicals (i.e., if(c("french","foreigner")=="french")
doesn't work) and R gives you the warning you're receiving.
By contrast, ifelse
is vectorized, so it can take your vectors (aka input variables) and test the logical condition on each of their elements, like you're used to in SAS. An alternative way to wrap your head around this would be to build a loop using if
and else
statements (as you've started to do here) but the vectorized ifelse
approach will be more efficient and involve generally less code.
Your syntax is incorrect. The var
keyword in your for
loop must be followed by a variable name, in this case its propName
var propValue;
for(var propName in nyc) {
propValue = nyc[propName]
console.log(propName,propValue);
}
I suggest you have a look here for some basics:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/for...in
Filter out the null instances before groupingBy.
Here is an exampleMyObjectlist.stream()
.filter(p -> p.getSomeInstance() != null)
.collect(Collectors.groupingBy(MyObject::getSomeInstance));
Make sure you are not using "PATH" as a variable, which will override the existing PATH for environment variables.
Maybe a bit simpler approach with ngInit
and Lodash's debounce
method without the need of custom directive:
Controller:
$scope.items = [1, 2, 3, 4];
$scope.refresh = _.debounce(function() {
// Debounce has timeout and prevents multiple calls, so this will be called
// once the iteration finishes
console.log('we are done');
}, 0);
Template:
<ul>
<li ng-repeat="item in items" ng-init="refresh()">{{item}}</li>
</ul>
There is even simpler pure AngularJS solution using ternary operator:
Template:
<ul>
<li ng-repeat="item in items" ng-init="$last ? doSomething() : null">{{item}}</li>
</ul>
Be aware that ngInit uses pre-link compilation phase - i.e. the expression is invoked before child directives are processed. This means that still an asynchronous processing might be required.
If it has to be "nested", this would be one way, to get your job done:
SELECT o.name AS country, o.headofstate
FROM country o
WHERE o.headofstate like 'A%'
AND (
SELECT i.population
FROM city i
WHERE i.id = o.capital
) > 100000
A JOIN
would be more efficient than a correlated subquery, though. Can it be, that who ever gave you that task is not up to speed himself?
Another correct way to get selected value would be using this selector:
$("option[value="0"]:selected")
Best for you!
It looks like you want:
public static string GetRandomBits()
Without static
, you would need an object before you can call the GetRandomBits()
method. However, since the implementation of GetRandomBits()
does not depend on the state of any Program
object, it's best to declare it static
.
I'm using Kotlin here
Just adding the information in here, you can also create readable file outside Private Directory for the apps by doing this example
var teks="your teks"
var NamaFile="Text1.txt"
var strwrt:FileWriter
strwrt=FileWriter(File("sdcard/${NamaFile}"))
strwrt.write(teks)
strwrt.close()
after that you can acces File Manager and look up on the Internal Storage. Text1.txt will be on there below all the folder.
You can use the regular expression /(?!$)/
:
"overpopulation".split(/(?!$)/)
The negative look-ahead assertion (?!$)
will match right in front of every character.
if x
is a vector with raw scores then scale(x)
is a vector with standardized scores.
Or manually: (x-mean(x))/sd(x)
Your compiler is right. You can't use the growthRate variable you declared in main as a function.
Maybe you should pick different names for your variables so they don't override function names?
All the random methods end up calling random.random()
so the best way is to call it directly:
[int(1000*random.random()) for i in xrange(10000)]
For example,
random.randint
calls random.randrange
.random.randrange
has a bunch of overhead to check the range before returning istart + istep*int(self.random() * n)
.NumPy is much faster still of course.
Statistics::Descriptive is a very decent Perl module for these types of calculations:
#!/usr/bin/perl
use strict; use warnings;
use Statistics::Descriptive qw( :all );
my $data = [
[ 0.01, 0.01, 0.02, 0.04, 0.03 ],
[ 0.00, 0.02, 0.02, 0.03, 0.02 ],
[ 0.01, 0.02, 0.02, 0.03, 0.02 ],
[ 0.01, 0.00, 0.01, 0.05, 0.03 ],
];
my $stat = Statistics::Descriptive::Full->new;
# You also have the option of using sparse data structures
for my $ref ( @$data ) {
$stat->add_data( @$ref );
printf "Running mean: %f\n", $stat->mean;
printf "Running stdev: %f\n", $stat->standard_deviation;
}
__END__
Output:
C:\Temp> g
Running mean: 0.022000
Running stdev: 0.013038
Running mean: 0.020000
Running stdev: 0.011547
Running mean: 0.020000
Running stdev: 0.010000
Running mean: 0.020000
Running stdev: 0.012566
No import is necessary as long as you declare both a.go
and b.go
to be in the same package. Then, you can use go run
to recognize multiple files with:
$ go run a.go b.go
You can just use:
<input type="radio" checked />
Using just the attribute checked without stating a value is the same as checked="checked"
.
str.join()
works fine in Python 3, you just need to get the order of the arguments correct
>>> str.join('.', ('a', 'b', 'c'))
'a.b.c'
$myObj = new stdClass();
// OR
$myObj = (object) [
"foo" => "Foo value",
"bar" => "Bar value"
];
I love how easy is to create objects of anonymous type in JavaScript:
//JavaScript
var myObj = {
foo: "Foo value",
bar: "Bar value"
};
console.log(myObj.foo); //Output: Foo value
So I always try to write this kind of objects in PHP like javascript does:
//PHP >= 5.4
$myObj = (object) [
"foo" => "Foo value",
"bar" => "Bar value"
];
//PHP < 5.4
$myObj = (object) array(
"foo" => "Foo value",
"bar" => "Bar value"
);
echo $myObj->foo; //Output: Foo value
But as this is basically an array you can't do things like assign anonymous functions to a property like js does:
//JavaScript
var myObj = {
foo: "Foo value",
bar: function(greeting) {
return greeting + " bar";
}
};
console.log(myObj.bar("Hello")); //Output: Hello bar
//PHP >= 5.4
$myObj = (object) [
"foo" => "Foo value",
"bar" => function($greeting) {
return $greeting . " bar";
}
];
var_dump($myObj->bar("Hello")); //Throw 'undefined function' error
var_dump($myObj->bar); //Output: "object(Closure)"
Well, you can do it, but IMO isn't practical / clean:
$barFunc = $myObj->bar;
echo $barFunc("Hello"); //Output: Hello bar
Also, using this synthax you can find some funny surprises, but works fine for most cases.
Based on bnkdev's answer I modified Narayana's Code to search all columns even numeric ones.
It'll run slower, but this version actually finds all matches not just those found in text columns.

You should be able to split('\n').length and get the line breaks.
update: this works on FF/Chrome but not IE.
<html>
<head>
<script src="jquery-1.3.2.min.js"></script>
<script>
$(document).ready(function() {
var arr = $("div").text().split('\n');
for (var i = 0; i < arr.length; i++)
$("div").after(i + '=' + arr[i] + '<br/>');

Use the insert
method of a list:
l = list(...)
l.insert(index, item)
Alternatively, you can use a slice notation:
l[index:index] = [item]
If you want to move an item that's already in the list to the specified position, you would have to delete it and insert it at the new position:
l.insert(newindex, l.pop(oldindex))
This will do the trick for you:
ng update @angular/cli @angular/core
ng s
or ng build
respectively.I need to select character to split urls in string, so I decided to create list of characters which could not be found in URL by myself:
>>> allowed = "-_.~!*'();:@&=+$,/?%#[]?@ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"
>>> from string import printable
>>> ''.join(set(printable).difference(set(allowed)))
'`" <\x0b\n\r\x0c\\\t{^}|>'
So, the possible choices are the newline, tab, space, backslash and "<>{}^|
. I guess I'll go with the space or newline. :)
That's How Python works. Try this :
from sqlitedbx import SqliteDBzz
Such that you can directly use the name without the enclosing module.Or just import the module and prepend 'sqlitedbx.' to your function,class etc
As long as it's supposed to return a reference to the object, returning a NULL should be good.
However, if it's returning the whole bloody thing (like in C++ if you do: 'return blah;' rather than 'return &blah;' (or 'blah' is a pointer), then you can't return a NULL, because it's not of type 'object'. In that case, throwing an exception, or returning a blank object that doesn't have a success flag set is how I would approach the problem.
One possible answer will be given when you run this snippet.

Rails has an except/except! method that returns the hash with those keys removed. If you're already using Rails, there's no sense in creating your own version of this.
class Hash
# Returns a hash that includes everything but the given keys.
# hash = { a: true, b: false, c: nil}
# hash.except(:c) # => { a: true, b: false}
# hash # => { a: true, b: false, c: nil}
#
# This is useful for limiting a set of parameters to everything but a few known toggles:
# @person.update(params[:person].except(:admin))
def except(*keys)
dup.except!(*keys)
end
# Replaces the hash without the given keys.
# hash = { a: true, b: false, c: nil}
# hash.except!(:c) # => { a: true, b: false}
# hash # => { a: true, b: false }
def except!(*keys)
keys.each { |key| delete(key) }
self
end
end
Index the list then the dict.

Solution 1 (Elegant approach with great user experience)
HTML
<input id="inputID" class="uppercase" name="inputName" value="" />
CSS
.uppercase{
text-transform: uppercase;
}
JS
$('#inputID').on('blur', function(){
this.value = this.value.toUpperCase();
});
By using CSS text-transform: uppercase;
you'll eliminate the animation of lower to uppercase as the user types into the field.
Use blur
event to handle converting to uppercase. This happens behind the scene as CSS took care of the user's visually appealing masking.
Solution 2 (Great, but less elegant)
If you insist on using keyup
, here it is...
$('#inputID').on('keyup', function(){
var caretPos = this.selectionStart;
this.value = this.value.toUpperCase();
this.setSelectionRange(caretPos, caretPos);
});
User would notice the animation of lowercase to uppercase as they type into the field. It gets the job done.
Solution 3 (Just get the job done)
$('#inputID').on('keyup', function(){
this.value = this.value.toUpperCase();
});
This method is most commonly suggested but I do not recommend.
The downside of this solution is you'll be annoying the user as the cursor's caret position keeps jumping to the end of the text after every key input. Unless you know your users will never encounter typos or they will always clear the text and retype every single time, this method works.
Xcode 4.3.2 didn't install "Command Line Tools" by default. I had to open Xcode Preferences / Downloads / Components Tab. It had a list of optional components with an "Install" button beside each. This includes "Command Line Tools" and components to support developing for older versions of iOS.
Now "make" is available and you can check by opening terminal and typing:make -v
The result should look like:GNU Make 3.81
You may need "make" even if you don't need Xcode, such as a Perl developer installing Perl Modules using cpan -i on the commandline.

You will need to copy the files as part of your build process. For example, you can use a npm postinstall
script to copy the files to the correct directory:
"postinstall": "cp -R node_modules/font-awesome/fonts ./public/"
For some build tools, there are preexisting font-awesome packages. For example, webpack has font-awesome-webpack which lets you simple require('font-awesome-webpack')
.
You can also put the conditional expression in brackets inside the list comprehension:
l = [22, 13, 45, 50, 98, 69, 43, 44, 1]
print [[x+5,x+1][x >= 45] for x in l]
[false,true][condition] is the syntax
Let is a mathematical statement that was adopted by early programming languages like Scheme and Basic. Variables are considered low level entities not suitable for higher levels of abstraction, thus the desire of many language designers to introduce similar but more powerful concepts like in Clojure, F#, Scala, where let
might mean a value, or a variable that can be assigned, but not changed, which in turn lets the compiler catch more programming errors and optimize code better.
JavaScript has had var
from the beginning, so they just needed another keyword, and just borrowed from dozens of other languages that use let
already as a traditional keyword as close to var
as possible, although in JavaScript let
creates block scope local variable instead.
How to use conditional in ng-class:

Solution 2:
<i ng-class="{true: 'icon-autoscroll', false: 'icon-autoscroll-disabled'}[autoScroll]"></i>
Solution 3 (angular v.1.1.4+ introduced support for ternary operator):
<i ng-class="autoScroll ? 'icon-autoscroll' : 'icon-autoscroll-disabled'"></i>

Rather than choosing date from date picker, you can enable the date box using javascript & enter the required date, this would avoid excessive time required to traverse through all date elements till you reach one you require to select.
Code for from date
((JavascriptExecutor)driver).executeScript ("document.getElementById('fromDate').removeAttribute('readonly',0);"); // Enables the from date box
WebElement fromDateBox= driver.findElement(By.id("fromDate"));
fromDateBox.clear();
fromDateBox.sendKeys("8-Dec-2014"); //Enter date in required format
Code for to date
((JavascriptExecutor)driver).executeScript ("document.getElementById('toDate').removeAttribute('readonly',0);"); // Enables the from date box
WebElement toDateBox= driver.findElement(By.id("toDate"));
toDateBox.clear();
toDateBox.sendKeys("15-Dec-2014"); //Enter date in required format
You can add it as script file. save the txt file with js suffix
in the head section add
<script src="fileName.js"></script>

I developed a new plugin called JavaScript Enhancements, that you can find on Package Control. It uses Flow (javascript static type checker from Facebook) under the hood.
Furthermore, it offers smart javascript autocomplete (compared to my other plugin JavaScript Completions), real-time errors, code refactoring and also a lot of features about creating, developing and managing javascript projects.
See the Wiki to know all the features that it offers!
An introduction to this plugin could be found in this css-tricks.com article: Turn Sublime Text 3 into a JavaScript IDE
Just some quick screenshots:
This can reasonably be achieved in a single line statement in API 12 and above. Below is an example where v
is the view you wish to animate;
v.animate().translationXBy(-1000).start();
This will slide the View
in question off to the left by 1000px. To slide the view back onto the UI we can simply do the following.
v.animate().translationXBy(1000).start();
I hope someone finds this useful.
Actually, there appears to now be a simple way. The following code works in TypeScript 1.5:
function sayName({ first, last = 'Smith' }: {first: string; last?: string }): void {
const name = first + ' ' + last;
console.log(name);
}
sayName({ first: 'Bob' });
The trick is to first put in brackets what keys you want to pick from the argument object, with key=value
for any defaults. Follow that with the :
and a type declaration.
This is a little different than what you were trying to do, because instead of having an intact params
object, you have instead have dereferenced variables.
If you want to make it optional to pass anything to the function, add a ?
for all keys in the type, and add a default of ={}
after the type declaration:
function sayName({first='Bob',last='Smith'}: {first?: string; last?: string}={}){
var name = first + " " + last;
alert(name);
}
sayName();

All of the DISPATCH_QUEUE_PRIORITY_X queues are concurrent queues (meaning they can execute multiple tasks at once), and are FIFO in the sense that tasks within a given queue will begin executing using "first in, first out" order. This is in comparison to the main queue (from dispatch_get_main_queue()), which is a serial queue (tasks will begin executing and finish executing in the order in which they are received).
So, if you send 1000 dispatch_async() blocks to DISPATCH_QUEUE_PRIORITY_DEFAULT, those tasks will start executing in the order you sent them into the queue. Likewise for the HIGH, LOW, and BACKGROUND queues. Anything you send into any of these queues is executed in the background on alternate threads, away from your main application thread. Therefore, these queues are suitable for executing tasks such as background downloading, compression, computation, etc.
Note that the order of execution is FIFO on a per-queue basis. So if you send 1000 dispatch_async() tasks to the four different concurrent queues, evenly splitting them and sending them to BACKGROUND, LOW, DEFAULT and HIGH in order (ie you schedule the last 250 tasks on the HIGH queue), it's very likely that the first tasks you see starting will be on that HIGH queue as the system has taken your implication that those tasks need to get to the CPU as quickly as possible.
Note also that I say "will begin executing in order", but keep in mind that as concurrent queues things won't necessarily FINISH executing in order depending on length of time for each task.
As per Apple:
A concurrent dispatch queue is useful when you have multiple tasks that can run in parallel. A concurrent queue is still a queue in that it dequeues tasks in a first-in, first-out order; however, a concurrent queue may dequeue additional tasks before any previous tasks finish. The actual number of tasks executed by a concurrent queue at any given moment is variable and can change dynamically as conditions in your application change. Many factors affect the number of tasks executed by the concurrent queues, including the number of available cores, the amount of work being done by other processes, and the number and priority of tasks in other serial dispatch queues.
Basically, if you send those 1000 dispatch_async() blocks to a DEFAULT, HIGH, LOW, or BACKGROUND queue they will all start executing in the order you send them. However, shorter tasks may finish before longer ones. Reasons behind this are if there are available CPU cores or if the current queue tasks are performing computationally non-intensive work (thus making the system think it can dispatch additional tasks in parallel regardless of core count).
The level of concurrency is handled entirely by the system and is based on system load and other internally determined factors. This is the beauty of Grand Central Dispatch (the dispatch_async() system) - you just make your work units as code blocks, set a priority for them (based on the queue you choose) and let the system handle the rest.
So to answer your above question: you are partially correct. You are "asking that code" to perform concurrent tasks on a global concurrent queue at the specified priority level. The code in the block will execute in the background and any additional (similar) code will execute potentially in parallel depending on the system's assessment of available resources.
The "main" queue on the other hand (from dispatch_get_main_queue()) is a serial queue (not concurrent). Tasks sent to the main queue will always execute in order and will always finish in order. These tasks will also be executed on the UI Thread so it's suitable for updating your UI with progress messages, completion notifications, etc.
JPA provides an SqlResultSetMapping
that allows you to map whatever returns from your native query into an Entity or a custom class.
EDIT JPA 1.0 does not allow mapping to non-entity classes. Only in JPA 2.1 a ConstructorResult has been added to map return values a java class.
Also, for OP's problem with getting count it should be enough to define a result set mapping with a single ColumnResult
I definitely wouldn't use Block1. It doesn't seem right having the Error block in an IF statement unrelated to Errors.
Blocks 2,3 & 4 I guess are variations of a theme. I prefer the use of Blocks 3 & 4 over 2 only because of a dislike of the GOTO statement; I generally use the Block4 method. This is one example of code I use to check if the Microsoft ActiveX Data Objects 2.8 Library is added and if not add or use an earlier version if 2.8 is not available.

One of the reason I found for this error is 'Packet Size=xxxxx' in connection string. if the value of xxxx is too large, we will see this error. Either remove this value and let SQL server handle it or keep it low, depending on the network capabilities.
dict.update()
looks like it will do what you want...
>> orig.update(extra)
>>> orig
{'A': 1, 'C': 3, 'B': 2, 'E': 5, 'D': 4}
>>>
Perhaps, though, you don't want to update your original dictionary, but work on a copy:
>>> dest = orig.copy()
>>> dest.update(extra)
>>> orig
{'A': 1, 'C': 3, 'B': 2}
>>> dest
{'A': 1, 'C': 3, 'B': 2, 'E': 5, 'D': 4}
The align-items
, or respectively align-content
attribute controls this behaviour.
align-items
defines the items' positioning perpendicularly to flex-direction
.
The default flex-direction
is row
, therfore vertical placement can be controlled with align-items
.
There is also the align-self
attribute to control the alignment on a per item basis.
#a {_x000D_
display:flex;_x000D_
_x000D_
align-items:flex-start;_x000D_
align-content:flex-start;_x000D_

css-tricks has an excellent article on the topic. I recommend reading it a couple of times.
Another workaround is to use grep -o
with a little regex magic to get three chars followed by the end of line:
$ foo=1234567890
$ echo $foo | grep -o ...$
890
To make it optionally get the 1 to 3 last chars, in case of strings with less than 3 chars, you can use egrep
with this regex:
$ echo a | egrep -o '.{1,3}$'
a
$ echo ab | egrep -o '.{1,3}$'
ab
$ echo abc | egrep -o '.{1,3}$'
abc
$ echo abcd | egrep -o '.{1,3}$'
bcd
You can also use different ranges, such as 5,10
to get the last five to ten chars.
it seems that you should set your command as an String[]
,for example:
String[] command = new String[]{"rmiregistry","2020"};
Runtime.getRuntime().exec(command);
it just like the style of main(String[] args)
.
Here's a fairly raw way to do it using bit fiddling to generate the binary strings.
The key bit to understand is:
(n & (1 << i)) and 1
Which will generate either a 0 or 1 if the i'th bit of n is set.
import binascii
def byte_to_binary(n):
return ''.join(str((n & (1 << i)) and 1) for i in reversed(range(8)))
def hex_to_binary(h):
return ''.join(byte_to_binary(ord(b)) for b in binascii.unhexlify(h))
print hex_to_binary('abc123efff')
>>> 1010101111000001001000111110111111111111
Edit: using the "new" ternary operator this:
(n & (1 << i)) and 1
Would become:
1 if n & (1 << i) or 0
(Which TBH I'm not sure how readable that is)
Just because it happened to me and can be useful. If you do this
try {
...
} catch (Exception e) {
log.error( "failed! {}", e );
}
you will get the header of the exception and not the whole stacktrace. Because the logger will think that you are passing a String.
Do it without {}
as skaffman said
Do you just want to know how to write a line to a file? First, you need to open the file:
f = open("filename.txt", 'w')
Then, you need to write the string to the file:
f.write("dict = {'one': 1, 'two': 2}" + '\n')
You can repeat this for each line (the +'\n'
adds a newline if you want it).
Finally, you need to close the file:
f.close()
You can also be slightly more clever and use with
:
with open("filename.txt", 'w') as f:
f.write("dict = {'one': 1, 'two': 2}" + '\n')
### repeat for all desired lines
This will automatically close the file, even if exceptions are raised.
But I suspect this is not what you are asking...

If you want an ANSI SQL-92 version:
select view_definition from information_schema.views where table_name = 'view_name';
Keep it simple:
import os
relevant_path = "[path to folder]"
included_extensions = ['jpg','jpeg', 'bmp', 'png', 'gif']
file_names = [fn for fn in os.listdir(relevant_path)
if any(fn.endswith(ext) for ext in included_extensions)]
I prefer this form of list comprehensions because it reads well in English.
I read the fourth line as: For each fn in os.listdir for my path, give me only the ones that match any one of my included extensions.
It may be hard for novice python programmers to really get used to using list comprehensions for filtering, and it can have some memory overhead for very large data sets, but for listing a directory and other simple string filtering tasks, list comprehensions lead to more clean documentable code.
The only thing about this design is that it doesn't protect you against making the mistake of passing a string instead of a list. For example if you accidentally convert a string to a list and end up checking against all the characters of a string, you could end up getting a slew of false positives.
But it's better to have a problem that's easy to fix than a solution that's hard to understand.
Assuming the changes you want are at the head of the branch you want the changes from, use git checkout

The HTML
<div>
element (or HTML Document Division Element) is the generic container for flow content, which does not inherently represent anything. It can be used to group elements for styling purposes (using the class or id attributes), or because they share attribute values, such as lang. It should be used only when no other semantic element (such as<article>

Combination of Mritunjay and Bartu's answers are full answer to this question. I copying the full example.
<input class="form-control" type="email" required="" placeholder="username"
oninvalid="this.setCustomValidity('Please Enter valid email')"

Here,
this.setCustomValidity('Please Enter valid email')" - Display the custom message on invalidated of the field
oninput="setCustomValidity('')" - Remove the invalidate message on validated filed.
If you go here you can find a comprehensive matrix that includes both the NLog and Log4Net libs as well as Enterprise Lib and other products.
Somebody could argue that the matrix is done in a way to underline the features of the only commercial lib present in the matrix. I think it's true but it was useful anyway to drive my choice versus NLog.

Updated.. I solved this issue by stating the charset on PDO connection as below:
"mysql:host=$host;dbname=$db;charset=utf8"
All data received was then in the correct charset for the rest of the code to use
To add onto the other answers that state that you might wish store variables in the application scope, for any long-running threads or other objects that need binding to your application where you are NOT using an activity (application is not an activity).. such as not being able to request a binded service.. then binding to the application instance is preferred. The only obvious warning with this approach is that the objects live for as long as the application is alive, so more implicit control over memory is required else you'll encounter memory-related problems like leaks.
Something else you may find useful is that in the order of operations, the application starts first before any activities. In this timeframe, you can prepare any necessary housekeeping that would occur before your first activity if you so desired.

You have to fetch the whole data in the list and then do the iteration as it is a file and will become inefficient otherwise.
private static final Type REVIEW_TYPE = new TypeToken<List<Review>>() {
}.getType();
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
List<Review> data = gson.fromJson(reader, REVIEW_TYPE); // contains the whole reviews list
data.toScreen(); // prints to screen some values
We can reverse Java number int or double using this :
int x = 5;
int y = -7;
x = x - (x*2); // reverse to negative
y = y - (y*2); // reverse to positif
Simple algorithm to reverse number :)
You could use a Polygon Clipping algorithm to find the intersection between two polygons. However these tend to be complicated algorithms when all of the edge cases are taken into account.
One implementation of polygon clipping that you can use your favorite search engine to look for is Weiler-Atherton. wikipedia article on Weiler-Atherton
Alan Murta has a complete implementation of a polygon clipper GPC.
Edit:
Another approach is to first divide each polygon into a set of triangles, which are easier to deal with. The Two-Ears Theorem by Gary H. Meisters does the trick. This page at McGill does a good job of explaining triangle subdivision.

The Linux Kernel refers to everything that runs in Kernel mode and is made up of several distinct layers. At the lowest layer, the Kernel interacts with the hardware via the HAL. At the middle level, the UNIX Kernel is divided into 4 distinct areas. The first of the four areas handles character devices, raw and cooked TTY and terminal handling. The second area handles network device drivers, routing protocols and sockets. The third area handles disk device drivers, page and buffer caches, file system, virtual memory, file naming and mapping. The fourth and last area handles process dispatching, scheduling, creation and termination as well as signal handling. Above all this we have the top layer of the Kernel which includes system calls, interrupts and traps. This level serves as the interface to each of the lower level functions. A programmer uses the various system calls and interrupts to interact with the features of the operating system.

Use following statement for error
be careful about your data take backup if data have in table.
ALTER TABLE your_table_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;
I'm a complete noob on Entity but this is how I would do it in theory...
var name = yourDbContext.MyTable.Find(1).Name;
If It's A Primary Key.
-- OR --
var name = yourDbContext.MyTable.SingleOrDefault(mytable => mytable.UserId == 1).Name;
-- OR --
For whole Column:
var names = yourDbContext.MyTable
.Where(mytable => mytable.UserId == 1)
.Select(column => column.Name); //You can '.ToList();' this....

Fix: You are missing a semi-colon (;) to separate the expressions
userListQuery = {

"isCameraAdded": true
}; // Without a semi colon, the error is produced
( cameraInfo.findtext != "" ) ? searchQuery : userListQuery;

I found the simplest solution is to add two registry entries as follows (run this in a command prompt with admin privileges):
reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /reg:32
reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SchUseStrongCrypto /t REG_DWORD /d 1 /reg:64
These entries seem to affect how the .NET CLR chooses a protocol when making a secure connection as a client.
There is more information about this registry entry here:
https://docs.microsoft.com/en-us/security-updates/SecurityAdvisories/2015/2960358#suggested-actions
Not only is this simpler, but assuming it works for your case, far more robust than a code-based solution, which requires developers to track protocol and development and update all their relevant code. Hopefully, similar environment changes can be made for TLS 1.3 and beyond, as long as .NET remains dumb enough to not automatically choose the highest available protocol.
NOTE: Even though, according to the article above, this is only supposed to disable RC4, and one would not think this would change whether the .NET client is allowed to use TLS1.2+ or not, for some reason it does have this effect.
NOTE: As noted by @Jordan Rieger in the comments, this is not a solution for POODLE, since it does not disable the older protocols a -- it merely allows the client to work with newer protocols e.g. when a patched server has disabled the older protocols. However, with a MITM attack, obviously a compromised server will offer the client an older protocol, which the client will then happily use.
TODO: Try to disable client-side use of TLS1.0 and TLS1.1 with these registry entries, however I don't know if the .NET http client libraries respect these settings or not:

One issue with REPLACE
will be where city names contain the district name. You can use something like.
SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)

JOIN dbo.Cities C
ON C.foo = O.foo
WHERE O.GKZ = '06440004'
When you use recv
in connection with select
if the socket is ready to be read from but there is no data to read that means the client has closed the connection.
Here is some code that handles this, also note the exception that is thrown when recv
is called a second time in the while loop. If there is nothing left to read this exception will be thrown it doesn't mean the client has closed the connection :
def listenToSockets(self):
while True:
changed_sockets = self.currentSockets
ready_to_read, ready_to_write, in_error = select.select(changed_sockets, [], [], 0.1)
for s in ready_to_read:
if s == self.serverSocket:
self.acceptNewConnection(s)
else:
self.readDataFromSocket(s)
And the function that receives the data :
def readDataFromSocket(self, socket):
data = ''
buffer = ''
try:
while True:
data = socket.recv(4096)
if not data:
break
buffer += data
except error, (errorCode,message):
# error 10035 is no data available, it is non-fatal
if errorCode != 10035:
print 'socket.error - ('+str(errorCode)+') ' + message
if data:
print 'received '+ buffer
else:
print 'disconnected'
var i = [NaN, 1,2,3];
var j = i.map(i =>{ return isNaN(i) ? 0 : i});
console.log(j)

The context parameter just sets the value of this
in the iterator function.
var someOtherArray = ["name","patrick","d","w"];
_.each([1, 2, 3], function(num) {
// In here, "this" refers to the same Array as "someOtherArray"
alert( this[num] ); // num is the value from the array being iterated
// so this[num] gets the item at the "num" index of
// someOtherArray.
}, someOtherArray);
Working Example: http://jsfiddle.net/a6Rx4/
It uses the number from each member of the Array being iterated to get the item at that index of someOtherArray
, which is represented by this
since we passed it as the context parameter.
If you do not set the context, then this
will refer to the window
object.
PHP preg functions needs your regex to be wrapped with a delimiter character, which can be any character. You can't use this delimiter character without escaping inside the regex. This should work (here the delimiter character is /):
preg_match('/\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}/', '2008-09-01 12:35:45');
// or this, to allow matching 0:00:00 time too.
preg_match('/\d{4}-\d{2}-\d{2} \d{1,2}:\d{2}:\d{2}/', '2008-09-01 12:35:45');
If you need to match lines that contain only datetime, add ^ and $ at the beginning and end of the regex.
preg_match('/^\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}$/', '2008-09-01 12:35:45');
You can do it by using the td's index:
var tdIndex = $td.index() + 1;
var $th = $('#table tr').find('th:nth-child(' + tdIndex + ')');
I encountered the same error, with the below code.
return this.state.employees.map((employee) => {
<option value={employee.id}>
{employee.name}
</option>
});
Above issue got resolved, when I changed curly braces to parenthesis, as indicated in the below modified code snippet.
return this.state.employees.map((employee) => (
<option value={employee.id}>
{employee.name}
</option>
));
As far as I see it's currently not possible to sort a Map properly.
The other solutions where the Map is converted into an array and sorted this way have the following bug:
var a = new Map([[1, 2], [3,4]])
console.log(a); // a = Map(2) {1 => 2, 3 => 4}
var b = a;
console.log(b); // b = Map(2) {1 => 2, 3 => 4}
a = new Map(); // this is when the sorting happens
console.log(a, b); // a = Map(0) {} b = Map(2) {1 => 2, 3 => 4}
The sorting creates a new object and all other pointers to the unsorted object get broken.
Use either of these depending how you want backslashes in the shell variables handled (avar
is an awk variable, svar
is a shell variable):
awk -v avar="$svar" '... avar ...' file
awk 'BEGIN{avar=ARGV[1];ARGV[1]=""}... avar ...' "$svar" file
See http://cfajohnson.com/shell/cus-faq-2.html#Q24 for details and other options. The first method above is almost always your best option and has the most obvious semantics.
You can do it with just xml.
the app:reverseLayout="true" do the job!

app:reverseLayout="true"

You can add this in your css file:
[data-role=page]{height: 100% !important; position:relative !important;}
[data-role=footer]{bottom:0; position:absolute !important; top: auto !important; width:100%;}
So the page data-role now have 100% height, and footer is in absolute position.
Also Yappo have wrote an excellent plugin that you can find here: jQuery Mobile in a iScroll plugin http://yappo.github.com/projects/jquery.mobile.iscroll/livedemo.html
hope you found the answer!
An answer update
You can now use the data-position="fixed"
attribute to keep your footer element on the bottom.
Docs and demos: http://view.jquerymobile.com/master/demos/toolbar-fixed/
give on .view-type
class float:left;
or delete the float:right;
of .view-name
edit: Wrap your div <div class="view-row">
with another div for example <div class="table">
and set the following css :
.table {
display:table;
width:100%;}
You have to use the table structure for correct results.
You might want to change selector:
$('input[name=q12_3]:checked').val()
If you always want to strip leading brackets:
"[12,23,987,43".gsub(/^\[/, "")
If you just want to remove the first character, and you know it won't be in a multibyte character set:
"[12,23,987,43"[1..-1]

To have the same flexibility in CONCAT_WS as in CONCAT (if you don't want the same separator between every member for instance) use the following:
SELECT CONCAT_WS("",affiliate_name,':',model,'-',ip,... etc)
The error is telling you it cannot find the class because it is not available in your application.
If you are using Maven, make sure you have the dependency for jstl
artifact:
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jstl</artifactId>
<version>1.2</version>
</dependency>
If you are not using it, just make sure you include the JAR in your classpath. See this answer for download links.
I got this exception because eclipse was working in a different version of jdk, just changed to the correct, clean and build and worked!
I've had problems trying to do it in pure CSS - depending on the font it can look a bit rubbish. As an alternative you can use SVG/VML to do it. There are libraries that help make it cross browser with ease e.g. Raphael and ExtJS. In ExtJS4 the code looks like this:
var drawComp = Ext.create('Ext.draw.Component', {
renderTo: Ext.getBody(), //or whatever..
height: 100, width: 100 //ditto..
});
var text = Ext.create('Ext.draw.Component', {
type: "text",
text: "The text to draw",
rotate: {
x: 0, y: 0, degrees: 270
},
x: -50, y: 10 //or whatever to fit (you could calculate these)..
});
text.show(true);
This will work in IE6+ and all modern browsers, however, unfortunately I think you need at least FF3.0.
You can use following SQL to restore if you've already created database
RESTORE DATABASE [YourDB]
FROM DISK = 'C:\YourDB.bak'
WITH MOVE 'YourDB' TO 'C:\YourDB.mdf',
MOVE 'YourDB_Log' TO 'C:\YourDB.ldf', REPLACE
Got this issue after I upgraded PostgreSQL 9.4 to 9.6. The 9.4 binary package had PgAdmin 3 while 9.6 came with PgAdmin 4. I resolved it after a clean installation (I completely uninstalled and reinstalled) of PostgreSQL.
However, under different circumstances, you could try running the pgAdmin 4 application as an Administrator. This should fix the error.
About this solution, we could just create a directive and attach it to the DOM element that has to get the focus when a given condition is satisfied. By following this approach we avoid coupling controller to DOM element ID's.
Sample code directive:
gbndirectives.directive('focusOnCondition', ['$timeout',
function ($timeout) {
var checkDirectivePrerequisites = function (attrs) {
if (!attrs.focusOnCondition && attrs.focusOnCondition != "") {
throw "FocusOnCondition missing attribute to evaluate";
}
}
return {
restrict: "A",
link: function (scope, element, attrs, ctrls) {
checkDirectivePrerequisites(attrs);
scope.$watch(attrs.focusOnCondition, function (currentValue, lastValue) {
if(currentValue == true) {
$timeout(function () {
element.focus();
});
}
});
}
};
}
]);
A possible usage
.controller('Ctrl', function($scope) {
$scope.myCondition = false;
// you can just add this to a radiobutton click value
// or just watch for a value to change...
$scope.doSomething = function(newMyConditionValue) {
// do something awesome
$scope.myCondition = newMyConditionValue;
};
});
HTML
<input focus-on-condition="myCondition">

Building on @IllidanS4 's answer, I have created a template class that allows virtually any member function with predefined arguments and class instance to be passed by reference for later calling.
template<class RET, class... RArgs> class Callback_t {
public:
virtual RET call(RArgs&&... rargs) = 0;
//virtual RET call() = 0;
};
template<class T, class RET, class... RArgs> class CallbackCalltimeArgs : public Callback_t<RET, RArgs...> {
public:
T * owner;
RET(T::*x)(RArgs...);
RET call(RArgs&&... rargs) {
return (*owner.*(x))(std::forward<RArgs>(rargs)...);
};
CallbackCalltimeArgs(T* t, RET(T::*x)(RArgs...)) : owner(t), x(x) {}
};
template<class T, class RET, class... Args> class CallbackCreattimeArgs : public Callback_t<RET> {
public:
T* owner;
RET(T::*x)(Args...);
RET call() {
return (*owner.*(x))(std::get<Args&&>(args)...);
};
std::tuple<Args&&...> args;
CallbackCreattimeArgs(T* t, RET(T::*x)(Args...), Args&&... args) : owner(t), x(x),
args(std::tuple<Args&&...>(std::forward<Args>(args)...)) {}
};
Test / example:
class container {
public:
static void printFrom(container* c) { c->print(); };
container(int data) : data(data) {};
~container() {};
void print() { printf("%d\n", data); };
void printTo(FILE* f) { fprintf(f, "%d\n", data); };
void printWith(int arg) { printf("%d:%d\n", data, arg); };
private:
int data;
};
int main() {
container c1(1), c2(20);
CallbackCreattimeArgs<container, void> f1(&c1, &container::print);
Callback_t<void>* fp1 = &f1;
fp1->call();//1
CallbackCreattimeArgs<container, void, FILE*> f2(&c2, &container::printTo, stdout);
Callback_t<void>* fp2 = &f2;
fp2->call();//20
CallbackCalltimeArgs<container, void, int> f3(&c2, &container::printWith);
Callback_t<void, int>* fp3 = &f3;
fp3->call(15);//20:15
}
Obviously, this will only work if the given arguments and owner class are still valid. As far as readability... please forgive me.
Edit: removed unnecessary malloc by making the tuple normal storage. Added inherited type for the reference. Added option to provide all arguments at calltime instead. Now working on having both....
Edit 2: As promised, both. Only restriction (that I see) is that the predefined arguments must come before the runtime supplied arguments in the callback function. Thanks to @Chipster for some help with gcc compliance. This works on gcc on ubuntu and visual studio on windows.

You can do something like this to read 10 bytes:
char buffer[10];
read(STDIN_FILENO, buffer, 10);
remember read() doesn't add '\0'
to terminate to make it string (just gives raw buffer).
To read 1 byte at a time:
char ch;
while(read(STDIN_FILENO, &ch, 1) > 0)
{
//do stuff
}
and don't forget to #include <unistd.h>
, STDIN_FILENO
defined as macro in this file.
There are three standard POSIX file descriptors, corresponding to the three standard streams, which presumably every process should expect to have:
Integer value Name
0 Standard input (stdin)
1 Standard output (stdout)
2 Standard error (stderr)
So instead STDIN_FILENO
you can use 0.
Edit:
In Linux System you can find this using following command:
$ sudo grep 'STDIN_FILENO' /usr/include/* -R | grep 'define'
/usr/include/unistd.h:#define STDIN_FILENO 0 /* Standard input. */
Notice the comment /* Standard input. */
If you use apachectl to start or stop, then you can find it with this command
apachectl -t -D DUMP_RUN_CFG
In Apache, you can add the woff2
mime type via your .htaccess
file as stated by this link.
AddType application/font-woff2 .woff2
In IIS, simply add the following mimeMap
tag into your web.config
file inside the staticContent
tag.
<configuration>
<system.webServer>
<staticContent>
<mimeMap fileExtension=".woff2" mimeType="application/font-woff2" />
it is not possible to import js file inside another js file
The way to use jquery inside js is
import the js in the html or whatever view page you are using inside which you are going to include the js file
view.html
<script src="<%=request.getContextPath()%>/js/jquery-1.11.3.js"></script>
<script src="<%=request.getContextPath()%>/js/default.js"></script>
default.js
$('document').ready(function() {
$('li#user').click(function() {
$(this).addClass('selectedEmp');
});
});
this will definitely work for you

Around 1:51 in the video, notice how she puts a <script>
tag in there? The way it works is like this:
Create an html file (that's just a text file with a .html
ending) somewhere on your computer. In the same folder that you put index.html
, put a javascript file (that's just a textfile with a .js
ending - let's call it game.js
). Then, in your index.html
file, put some html that includes the script tag with game.js
, like Mary did in the video. index.html
should look something like this:
<html>
<head>
<script src="game.js"></script>
</head>
</html>
Now, double click on that file in finder, and it should open it up in your browser. To open up the console to see the output of your javascript code, hit Command-alt-j (those three buttons at the same time).
Good luck on your journey, hope it's as fun for you as it has been for me so far :)
If you're using Google Maps v2, call checkResize()

Google Maps JavaScript API v2 was deprecated in 2011. It is not available anymore.

You could have the function take a variable as the first arg and modify the variable with the string you want to return.
#!/bin/bash
set -x
function pass_back_a_string() {
eval "$1='foo bar rab oof'"
}
return_var=''
pass_back_a_string return_var
echo $return_var
Prints "foo bar rab oof".
Edit: added quoting in the appropriate place to allow whitespace in string to address @Luca Borrione's comment.
Edit: As a demonstration, see the following program. This is a general-purpose solution: it even allows you to receive a string into a local variable.
#!/bin/bash
set -x
function pass_back_a_string() {
eval "$1='foo bar rab oof'"
}
return_var=''
pass_back_a_string return_var
echo $return_var
function call_a_string_func() {
local lvar=''
pass_back_a_string lvar
echo "lvar='$lvar' locally"
}
call_a_string_func
echo "lvar='$lvar' globally"
This prints:
+ return_var=
+ pass_back_a_string return_var
+ eval 'return_var='\''foo bar rab oof'\'''
++ return_var='foo bar rab oof'
+ echo foo bar rab oof
foo bar rab oof
+ call_a_string_func
+ local lvar=
+ pass_back_a_string lvar
+ eval 'lvar='\''foo bar rab oof'\'''
++ lvar='foo bar rab oof'
+ echo 'lvar='\''foo bar rab oof'\'' locally'
lvar='foo bar rab oof' locally
+ echo 'lvar='\'''\'' globally'
lvar='' globally
Edit: demonstrating that the original variable's value is available in the function, as was incorrectly criticized by @Xichen Li in a comment.
#!/bin/bash
set -x
function pass_back_a_string() {
eval "echo in pass_back_a_string, original $1 is \$$1"
eval "$1='foo bar rab oof'"
}
return_var='original return_var'
pass_back_a_string return_var
echo $return_var
function call_a_string_func() {
local lvar='original lvar'
pass_back_a_string lvar
echo "lvar='$lvar' locally"
}
call_a_string_func
echo "lvar='$lvar' globally"
This gives output:
+ return_var='original return_var'
+ pass_back_a_string return_var
+ eval 'echo in pass_back_a_string, original return_var is $return_var'
++ echo in pass_back_a_string, original return_var is original return_var
in pass_back_a_string, original return_var is original return_var
+ eval 'return_var='\''foo bar rab oof'\'''
++ return_var='foo bar rab oof'
+ echo foo bar rab oof
foo bar rab oof
+ call_a_string_func
+ local 'lvar=original lvar'
+ pass_back_a_string lvar
+ eval 'echo in pass_back_a_string, original lvar is $lvar'
++ echo in pass_back_a_string, original lvar is original lvar
in pass_back_a_string, original lvar is original lvar
+ eval 'lvar='\''foo bar rab oof'\'''
++ lvar='foo bar rab oof'
+ echo 'lvar='\''foo bar rab oof'\'' locally'
lvar='foo bar rab oof' locally
+ echo 'lvar='\'''\'' globally'
lvar='' globally
In my mind true way is:
# add READ permission to all directories and files under your DocumentRoot
sudo chmod +r /path/to/DocumentRoot/ -R
# add EXECUTE permission to all DIRECTORIES under your DocumentRoot
find /path/to/DocumentRoot/ -type d -exec chmod +x {} \;
var ofd = new Microsoft.Win32.OpenFileDialog() {Filter = "JPEG Files (*.jpeg)|*.jpeg|PNG Files (*.png)|*.png|JPG Files (*.jpg)|*.jpg|GIF Files (*.gif)|*.gif"};
var result = ofd.ShowDialog();
if (result == false) return;
textBox1.Text = ofd.FileName;

You can download the sample file. Just place the html
you want to convert in the files
folder and run. It will automatically generate the pdf file and place it in the same folder. But in your case, you can specify your html path in the htmlFileName
variable.
With jQuery, you can try to call trigger:
$(window).trigger('resize');
Neither of the answers here helped me. The problem was: I was using the slim build of jQuery, which had some things removed, ajax being one of them.
The solution: Just download the regular (compressed or not) version of jQuery here and include it in your project.
This is the case from the question because the OP wants to commit to a new branch and also applies if your changes are compatible with the target branch without triggering an overwrite.
As in the accepted answer by John Brodie, you can simply checkout the new branch and commit the work:
git checkout -b branch_name
git add <files>
git commit -m "message"
If you get the error:
error: Your local changes to the following files would be overwritten by checkout:
...
Please commit your changes or stash them before you switch branches
Then you can stash your work, create a new branch, then pop your stash changes, and resolve the conflicts:
git stash
git checkout -b branch_name
git stash pop
It will be as if you had made those changes after creating the new branch. Then you can commit as usual:
git add <files>
git commit -m "message"
See the answer by Carl Norum with cherry-picking, which is the right tool in this case:
git checkout <target name>
git cherry-pick <original branch>
See the answer by joeytwiddle on this potential duplicate. Follow any of the above steps as appropriate, then roll back the original branch:
git branch -f <original branch> <earlier commit id>
If you have pushed your changes to a shared remote like GitHub, you should not attempt this roll-back unless you know what you are doing.
No you can't - IP addresses get reallocated and reassigned from time to time, so the mapping of IP to location will also change over time.
If you want to find out the location that an IP address currently maps to you can either download a geolocation database, such as GeoLite from MaxMind, or use an API like http://ipinfo.io (my own service) which will also give you additional details:
$ curl ipinfo.io/8.8.8.8
{
"ip": "8.8.8.8",
"hostname": "google-public-dns-a.google.com",
"loc": "37.385999999999996,-122.0838",
"org": "AS15169 Google Inc.",
"city": "Mountain View",
"region": "California",
"country": "US",
"phone": 650
}
You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model
Post.objects.all().delete()
and to delete any Post with a future publication date
Post.objects.filter(pub_date__gt=datetime.now()).delete()
You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.
EDIT:
Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForm
s and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.
Consider also passing in the shell variable (EMAILID) as a jq variable (here also EMAILID, for the sake of illustration):
projectID=$(jq -r --arg EMAILID "$EMAILID" '
.resource[]
| select(.username==$EMAILID)
| .id' file.json)
For the record, another possibility would be to use jq's env
function for accessing environment variables. For example, consider this sequence of bash commands:
[email protected] # not exported
EMAILID="$EMAILID" jq -n 'env.EMAILID'
The output is a JSON string:
"[email protected]"
Just to round out Reed's answer, you can either get the Button
objects from the Form
or other container and add the handler, or you could create the Button
objects programmatically.
If you get the Button
objects from the Form
or other container, then you can iterate over the Controls
collection of the Form
or other container control, such as Panel
or FlowLayoutPanel
and so on. You can then just add the click handler with
AddHandler ctrl.Click, AddressOf Me.Button_Click
(variables as in the code below),
but I prefer to check the type of the Control
and cast to a Button
so as I'm not adding click handlers for any other controls in the container (such as Labels). Remember that you can add handlers for any event of the Button
at this point using AddHandler
.
Alternatively, you can create the Button
objects programmatically, as in the second block of code below.
Then, of course, you have to write the handler method, as in the third code block below.
Here is an example using Form
as the container, but you're probably better off using a Panel
or some other container control.
Dim btn as Button = Nothing
For Each ctrl As Control in myForm.Controls
If TypeOf ctrl Is Button Then
btn = DirectCast(ctrl, Button)
AddHandler btn.Click, AddressOf Me.Button_Click ' From answer by Reed.
End If
Next
Alternatively creating the Button
s programmatically, this time adding to a Panel
container.
Dim Panel1 As new Panel()
For i As Integer = 1 to 100
btn = New Button()
' Set Button properties or call a method to do so.
Panel1.Controls.Add(btn) ' Add Button to the container.
AddHandler btn.Click, AddressOf Me.Button_Click ' Again from the answer by Reed.
Next
Then your handler will look something like this
Private Sub Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
' Handle your Button clicks here
End Sub
WIth the Help of @excray's comment, I manage to figure it out the answer, What we need to do is actually write a simple for loop to iterate over the two arrays that represent the train data and test data.
First implement a simple lambda function to hold formula for the cosine calculation:
cosine_function = lambda a, b : round(np.inner(a, b)/(LA.norm(a)*LA.norm(b)), 3)
And then just write a simple for loop to iterate over the to vector, logic is for every "For each vector in trainVectorizerArray, you have to find the cosine similarity with the vector in testVectorizerArray."

You can resolve this error by changing the web.config file.
With ASP.NET 4.0, add the following lines to your web.config:
<system.serviceModel>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
With ASP.NET 2.0/3.0/3.5, add the following lines to your web.config:

I see some of you doing return self
in __iter__
. I just wanted to note that __iter__
itself can be a generator (thus removing the need for __next__
and raising StopIteration
exceptions)
class range:
def __init__(self,a,b):
self.a = a
self.b = b
def __iter__(self):
i = self.a
while i < self.b:
yield i
i+=1
Of course here one might as well directly make a generator, but for more complex classes it can be useful.
Don't think so. I've always had to write them or use someone else's work to get that info. Has to be reflection as far as i'm aware.
EDIT:
Check this out. I was investigating some debugging on long object graphs and noticed this when i Add Watches, VS throws in this class: Mscorlib_CollectionDebugView<>
. It's an internal type for displaying collections nicely for viewing in the watch windows/code debug modes. Now coz it's internal you can reference it, but u can use Reflector to copy (from mscorlib) the code and have your own (the link above has a copy/paste example). Looks really useful.
For same error code i had quite different reason, I'm sharing here to help
I had web api action like below
public IHttpActionResult GetBooks (int id)
I changed the method to accept two parameters category and author so i changed the parameters as below, i also put the attribute [Httppost]
public IHttpActionResult GetBooks (int category, int author)
I also changed ajax options like below and at this point i start getting error 405 method not allowed
var options = {
url: '/api/books/GetBooks',
type: 'POST',
dataType: 'json',
cache: false,
traditional: true,
data: {
category: 1,
author: 15
}
}
When i created class for web api action parameters like below error was gone
public class BookParam
{
public int Category { get; set; }
public int Author { get; set; }
}
public IHttpActionResult GetBooks (BookParam param)
List can be instantiated by any class implementing the interface.By this way,Java provides us polymorphic behaviour.See the example below:
List<String> list = new ArrayList<String>();
Instead of instantiating an ArrayList directly,I am using a List to refer to ArrayList object so that we are using only the List interface methods and do not care about its actual implementation.
Examples of classes implementing List are ArrayList,LinkedList,Vector.You probably want to create a List depending upon your requirements.
Example:- a LinkedList is more useful when you hve to do a number of inertion or deletions .Arraylist is more performance intensive as it is backed by a fixed size array and array contents have to be changed by moving or regrowing the array.
Again,using a List we can simply change our object instantiation without changing any code further in your programs.
Suppose we are using ArrayList<String> value = new ArrayList<String>();
we may use a specific method of ArrrayList and out code will not be robust
By using List<String> value = new ArrayList<String>();
we are making sure we are using only List interface methods..and if we want to change it to a LinkedList we simply have to change the code :
List<String> value = new ArrayList<String>();
------ your code uses List interface methods.....
value = new LinkedList<String>();
-----your code still uses List interface methods and we do not have to change anything---- and we dont have to change anything in our code further
By the way a LinkedList also works a Deque which obviously also you cannot instantiate as it is also an interface
You can use django-ipware which supports Python 2 & 3 and handles IPv4 & IPv6.
Install:
pip install django-ipware
Simple Usage:
# In a view or a middleware where the `request` object is available
from ipware import get_client_ip
ip, is_routable = get_client_ip(request)
if ip is None:
# Unable to get the client's IP address
else:
# We got the client's IP address
if is_routable:
# The client's IP address is publicly routable on the Internet
else:
# The client's IP address is private
# Order of precedence is (Public, Private, Loopback, None)
Advanced Usage:
Custom Header - Custom request header for ipware to look at:
i, r = get_client_ip(request, request_header_order=['X_FORWARDED_FOR'])
i, r = get_client_ip(request, request_header_order=['X_FORWARDED_FOR', 'REMOTE_ADDR'])
Proxy Count - Django server is behind a fixed number of proxies:
i, r = get_client_ip(request, proxy_count=1)
Trusted Proxies - Django server is behind one or more known & trusted proxies:
i, r = get_client_ip(request, proxy_trusted_ips=('177.2.2.2'))
# For multiple proxies, simply add them to the list
i, r = get_client_ip(request, proxy_trusted_ips=('177.2.2.2', '177.3.3.3'))
# For proxies with fixed sub-domain and dynamic IP addresses, use partial pattern
i, r = get_client_ip(request, proxy_trusted_ips=('177.2.', '177.3.'))
Note: read this notice.
You need to use find
instead of grep
in this case.
You can also use find
in combination with grep
or egrep
:
$ find | grep "f[[:alnum:]]\.frm"

The jQueryUI provides a extension to animate
function that allows you to animate css class.
edit: Example here
There are also methods to add/remove/toggle class which you might also be interested in.
I would prefere
if (!myStr.empty())
{
//do something
}
Also you don't have to write std::string a = "";
. You can just write std::string a;
- it will be empty by default
You don't need JDK
to run Java based programs. JDK
is for development which stands for Java Development Kit
.
You need JRE
which should be there in Mac.
Try: java -jar Myjar_file.jar
EDIT: According to this article, for Mac OS 10
The Java runtime is no longer installed automatically as part of the OS installation.
Then, you need to install JRE to your machine.
List <SomeEnum> theList = Enum.GetValues(typeof(SomeEnum)).Cast<SomeEnum>().ToList();
function add(){
var first=parseFloat($("#first").val());
var second=parseFloat($("#second").val());
$("#result").val(+(first+second).toFixed(2));
}
If you are using Spring Framework with application.yml
and having trouble to make the test find the SQL file on the INIT
property, you can use the classpath:
notation.
For example, if you have a init.sql
SQL file on the src/test/resources
, just use:
url=jdbc:h2:~/test;INIT=RUNSCRIPT FROM 'classpath:init.sql';DB_CLOSE_DELAY=-1;
+'' or +[] evaluates 0.
++[[]][+[]]+[+[]] = 10
++[''][0] + [0] : First part is gives zeroth element of the array which is empty string
1+0

System.out.println("Output from Server .... \n");
String output = response.getEntity(String.class);
System.out.println(output);
} catch (Exception e) {
e.printStackTrace();
}
}
}
The only other thing I would add is to make it a tad more flexible. Most times I'll have a trivial java file I want to run like - Main.java, Simple.java, Example.java, or Playground.java (you get the idea).
I use the following to strike off a javac and corresponding java.
@echo off
javac %~n1.java
java %~n1
The %~n1 gets the filename (sans extension) of the first argument passed to the batch file. So this way I can run it using tab completion and not have to worry about it working with either the .class or .java extension.
So both of the following will have the same result:
run.bat Main.class
and
run.bat Main.java
Doesn't 100% answer the original posters question, but I think it is a good next step/evolution for simple javac/java programs.
Use CHAR
:
=Char(34)&"This is in quotes"&Char(34)
Should evaluate to:
"This is in quotes"
If you always search based on value3
, you could store the objects in a Map:
Map<String, List<Sample>> map = new HashMap <>();
You can then populate the map with key = value3
and value = list of Sample objects with that same value3
property.
You can then query the map:
List<Sample> allSamplesWhereValue3IsDog = map.get("Dog");
Note: if no 2 Sample
instances can have the same value3
, you can simply use a Map<String, Sample>
.
I am working with Meteor and I just got the same problem. The cause of my bug was this:
{{#if tourmanager}}
{{>contactInformation tourmanager}}
{{else}}
<a href="#addArtistTourmanagerModal" data-toggle="modal"><i class="fa fa-plus"></i> Tourmanager toevoegen</a>
{{>addArtistTourmanagerModal}}
{{/if}}
As you can see I added the modal in the else, so when my modal updated the contactinformation the if had another state. This caused the modal template to be left out of the DOM just before it would close.
The solution: move the modal out of the if-else:
{{#if tourmanager}}
{{>contactInformation tourmanager}}
{{else}}
<a href="#addArtistTourmanagerModal" data-toggle="modal"><i class="fa fa-plus"></i> Tourmanager toevoegen</a>
{{>addArtistTourmanagerModal}}
{{/if}}
If all your rows have equal height, you should definitely take a look at the virtualizing ng-repeat: http://kamilkp.github.io/angular-vs-repeat/
This demo looks very promising (and it supports inertial scrolling)
For all those recommending using table variables, be cautious in doing so. Table variable cannot be indexed whereas a temp table can be. A table variable is best when working with small amounts of data but if you are working on larger sets of data (e.g. 50k records) a temp table will be much faster than a table variable.
Also keep in mind that you can't rely on a try/catch to force a cleanup within the stored procedure. certain types of failures cannot be caught within a try/catch (e.g. compile failures due to delayed name resolution) if you want to be really certain you may need to create a wrapper stored procedure that can do a try/catch of the worker stored procedure and do the cleanup there.
e.g. create proc worker AS BEGIN -- do something here END
create proc wrapper AS
BEGIN
Create table #...
BEGIN TRY
exec worker
exec worker2 -- using same temp table
-- etc
END TRY
END CATCH
-- handle transaction cleanup here
drop table #...
END CATCH
END
One place where table variables are always useful is they do not get rolled back when a transaction is rolled back. This can be useful for capturing debug data that you want to commit outside the primary transaction.

The position relative is important, and i just stumbled about it. Could not make it work without it.
I'd like to provide an answer for the case that you do not have control over the code that opens the connection. Like I did when using the URLClassLoader
to load a jar file from a password protected server.
The Authenticator
solution would work but has the drawback that it first tries to reach the server without a password and only after the server asks for a password provides one. That's an unnecessary roundtrip if you already know the server would need a password.
public class MyStreamHandlerFactory implements URLStreamHandlerFactory {
private final ServerInfo serverInfo;
public MyStreamHandlerFactory(ServerInfo serverInfo) {
this.serverInfo = serverInfo;
}
@Override
public URLStreamHandler createURLStreamHandler(String protocol) {
switch (protocol) {
case "my":
return new MyStreamHandler(serverInfo);
default:
return null;
}
}
}
public class MyStreamHandler extends URLStreamHandler {
private final String encodedCredentials;
public MyStreamHandler(ServerInfo serverInfo) {
String strCredentials = serverInfo.getUsername() + ":" + serverInfo.getPassword();
this.encodedCredentials = Base64.getEncoder().encodeToString(strCredentials.getBytes());
}
@Override
protected URLConnection openConnection(URL url) throws IOException {
String authority = url.getAuthority();
String protocol = "http";
URL directUrl = new URL(protocol, url.getHost(), url.getPort(), url.getFile());
HttpURLConnection connection = (HttpURLConnection) directUrl.openConnection();
connection.setRequestProperty("Authorization", "Basic " + encodedCredentials);
return connection;
}
}
This registers a new protocol my
that is replaced by http
when credentials are added. So when creating the new URLClassLoader
just replace http
with my
and everything is fine. I know URLClassLoader
provides a constructor that takes an URLStreamHandlerFactory
but this factory is not used if the URL points to a jar file.
The answer of the user load step worked for me.
Sometimes is need edit the file in /etc/mysql/my.cnf
add line to client
[client]
password = your_mysql_root_password
port = 3306
host = 127.0.0.1
socket = /var/lib/mysql/mysql.sock
In my case i use the replace method by testing every entity in every variable, my code looks like this:
text = text.replace("Ç", "Ç");
text = text.replace("ç", "ç");
text = text.replace("Á", "Á");
text = text.replace("Â", "Â");
text = text.replace("Ã", "Ã");
text = text.replace("É", "É");
text = text.replace("Ê", "Ê");
text = text.replace("Í", "Í");
text = text.replace("Ô", "Ô");
text = text.replace("Õ", "Õ");
text = text.replace("Ó", "Ó");
text = text.replace("Ú", "Ú");
text = text.replace("á", "á");
text = text.replace("â", "â");
text = text.replace("ã", "ã");
text = text.replace("é", "é");
text = text.replace("ê", "ê");
text = text.replace("í", "í");
text = text.replace("ô", "ô");
text = text.replace("õ", "õ");
text = text.replace("ó", "ó");
text = text.replace("ú", "ú");
In my case this worked very well.
you should you use following code
$configValue = Mage::getStoreConfig(
'sectionName/groupName/fieldName',
Mage::app()->getStore()
);
Mage::app()->getStore()
this will add store code in fetch values so that you can get correct configuration values for current store this will avoid incorrect store's values because magento is also use for multiple store/views so must add store code to fetch anything in magento.
if we have more then one store or multiple views configured then this will insure that we are getting values for current store
I've made a custom date string format function, you can use that.
var getDateString = function(date, format) {
var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'],
getPaddedComp = function(comp) {
return ((parseInt(comp) < 10) ? ('0' + comp) : comp)
},
formattedDate = format,
o = {
"y+": date.getFullYear(), // year
"M+": months[date.getMonth()], //month
"d+": getPaddedComp(date.getDate()), //day
"h+": getPaddedComp((date.getHours() > 12) ? date.getHours() % 12 : date.getHours()), //hour
"H+": getPaddedComp(date.getHours()), //hour
"m+": getPaddedComp(date.getMinutes()), //minute
"s+": getPaddedComp(date.getSeconds()), //second
"S+": getPaddedComp(date.getMilliseconds()), //millisecond,
"b+": (date.getHours() >= 12) ? 'PM' : 'AM'
};
for (var k in o) {
if (new RegExp("(" + k + ")").test(format)) {
formattedDate = formattedDate.replace(RegExp.$1, o[k]);
}
}
return formattedDate;
};
And now suppose you've :-
var date = "2014-07-12 10:54:11";
So to format this date you write:-
var formattedDate = getDateString(new Date(date), "d-M-y")
.class {
font-size: clamp(minimum-size, prefered-size, maximum-size)
}
using this you could set it up so prefered and max values are 5vw but the minimum is 15px or something so it won't go over 5vw but if 5vw < 15px it will stick to 15px
You should use NSError object.
let error = NSError(domain:"", code:401, userInfo:[ NSLocalizedDescriptionKey: "Invalid access token"])
Then cast NSError to Error object
If you want to change a color quickly (and you don't have Hex numbers memorized) android has a few preset colors you can access like this:
android:background="@android:color/black"
There are 15 colors you can choose from which is nice for testing things out quickly, and you don't need to set up additional files.
Setting up a values/colors.xml file and using straight Hex like explained above will still work.

In my case I had a multi module project just like you. I had to change a group Id of one of the external libraries my project was depending on as shown below.
From:
<dependencyManagement>
<dependency>
<groupId>org.thirdparty</groupId>
<artifactId>calculation-api</artifactId>
<version>2.0</version>
<type>jar</type>
<scope>provided</scope>
</dependency>
<dependencyManagement>
To:
<dependencyManagement>
<dependency>
<groupId>org.thirdparty.module</groupId>
<artifactId>calculation-api</artifactId>
<version>2.0</version>
<type>jar</type>
<scope>provided</scope>
</dependency>
<dependencyManagement>
Pay attention to the <groupId> section. It turned out that I was forgetting to modifiy the corresponding section of the submodules that define this dependency in their pom files.
It drove me very crazy because the module was available locally.

sys.argv
is the list of arguments passed to the Python program. The first argument, sys.argv[0]
, is actually the name of the program as it was invoked. That's not a Python thing, but how most operating systems work. The reason sys.argv[0]
exists is so you can change your program's behaviour depending on how it was invoked. sys.argv[1]
is thus the first argument you actually pass to the program.
Because lists (like most sequences) in Python start indexing at 0, and because indexing past the end of the list is an error, you need to check if the list has length 2 or longer before you can access sys.argv[1]
.
You'll want to use the GetExtensionName method on the FileSystemObject object.
Set x = CreateObject("scripting.filesystemobject")
WScript.Echo x.GetExtensionName("foo.pdf")
In your example, try using this
For Each objFile in colFiles
If UCase(objFSO.GetExtensionName(objFile.name)) = "PDF" Then
Wscript.Echo objFile.Name
End If

Assuming they are all defined in the same assembly, you can do:
IEnumerable<AbstractDataExport> exporters = typeof(AbstractDataExport)
.Assembly.GetTypes()
.Where(t => t.IsSubclassOf(typeof(AbstractDataExport)) && !t.IsAbstract)
.Select(t => (AbstractDataExport)Activator.CreateInstance(t));
The question is a few months old but for other people looking --
A simpler way to import a large file is to make a sub directory 'upload' in your folder c:/wamp/apps/phpmyadmin3.5.2 and edit this line in the config.inc.php file in the same directory to include the folder name $cfg['UploadDir'] = 'upload';
Then place the incoming .sql file in the folder /upload.
Working from inside the phpmyadmin console, go to the new database and import. You will now see an additional option to upload files from that folder. Chose the correct file and be a little patient. It works.
If you still get a time out error try adding $cfg['ExecTimeLimit'] = 0; to the same config.inc.php file.
I have had difficulty importing an .sql file where the user name was root and the password differed from my the root password on my new server. I simply took off the password before I exported the .sql file and the import worked smoothly.

You can use php built in CONCAT() for this.
SELECT CONCAT(`name`, ' ', `email`) as password_email FROM `table`;
change filed name as your requirement
then the result is
and if you want to concat same filed using other field which same then
SELECT filed1 as category,filed2 as item, GROUP_CONCAT(CAST(filed2 as CHAR)) as item_name FROM `table` group by filed1

I'm assuming you are having at least OSX 10.7, so go ahead into the applications folder (Click on Finder icon > On the Sidebar, you'll find "Applications", click on it ), delete the "Xcode" icon. That will remove Xcode from your system completely. Restart your mac.
Now go to https://developer.apple.com/download/more/ and download an older version of Xcode, as needed and install. You need an Apple ID to login to that portal.
You may also get that error when CSRF "token" for the active user session is out of date, even if the token was specified in ajax request.
You'll need to save as a blob, LONGBLOB datatype in mysql will work.
Ex:
CREATE TABLE 'test'.'pic' (
'idpic' INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
'caption' VARCHAR(45) NOT NULL,
'img' LONGBLOB NOT NULL,
PRIMARY KEY ('idpic')

As others have said, its a bad practice but it can be done. Not sure if this code would scale well, though.
I found this url to be very useful: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/2cdcab2e-ea49-4fd5-b2b8-13824ab4619b/help-server-not-listening-on-1433
In particular, my problem was that I did not enable the TCP/IP in Sql Server Configuration Manager->SQL Server Network Configuration->Protocols for SQLEXPRESS.
Once you open it, you have to go to the IP Addresses tab and for me, changing IPAll to TCP port 1433 and deleting the TCP Dynamic Ports value worked.
Follow the other steps to make sure 1433 is listening (Use netstat -an to make sure 0.0.0.0:1433 is LISTENING.), and that you can telnet to the port from the client machine.
Finally, I second the suggestion to remove the \SQLEXPRESS from the connection.
EDIT: I should note I am using SQL Server 2014 Express.
Just add the column names, yes you can use Null instead but is is a very bad idea to not use column names in any insert, ever.
Serhii's suggestion works and here is some more detail.
If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents
export JAVA_OPTS="-server -Xmx512m"
For Windows you will need, in setenv.bat, something like
set JAVA_OPTS=-server -Xmx768m
Hope this helps, Glenn
From the official docs:
interval The amount of time to delay between automatically cycling an item. If false, carousel will not automatically cycle.
You can either pass this value with javascript or using a data-interval="false"
attribute.
please import requestoptions from angular cors
import {RequestOptions, Request, Headers } from '@angular/http';
and add request options in your code like given below
let requestOptions = new RequestOptions({ headers:null, withCredentials:
true });
send request option in your api request
code snippet below-
let requestOptions = new RequestOptions({ headers:null,
withCredentials: true });
return this.http.get(this.config.baseUrl +
this.config.getDropDownListForProject, requestOptions)
.map(res =>
{
if(res != null)
{
return res.json();
//return true;
}
})
.catch(this.handleError);
}
and add CORS in your backend PHP code where all api request will land first.
try this and let me know if it is working or not i had a same issue i was adding CORS from angular5 that was not working then i added CORS to backend and it worked for me
You can't wait()
on an object unless the current thread owns that object's monitor. To do that, you must synchronize
on it:
class Runner implements Runnable
{
public void run()
{
try
{
synchronized(Main.main) {
Main.main.wait();
}
} catch (InterruptedException e) {}
System.out.println("Runner away!");
}
}
The same rule applies to notify()
/notifyAll()
as well.
The Javadocs for wait()
mention this:
This method should only be called by a thread that is the owner of this object's monitor. See the
Throws:notify
method for a description of the ways in which a thread can become the owner of a monitor.
IllegalMonitorStateException
– if the current thread is not the owner of this object's monitor.
And from notify()
:
A thread becomes the owner of the object's monitor in one of three ways:
- By executing a synchronized instance method of that object.
- By executing the body of a
synchronized
statement that synchronizes on the object.- For objects of type
Class
, by executing a synchronized static method of that class.
If you're using AppCompat
, declare your activity in AndroidManifest.xml
as follows:
<activity
android:name=".SomeActivity"
...
android:theme="@style/Theme.AppCompat.Light.NoActionBar" />
In certain cases, it might be necessary to restrict the display of a webpage to a document mode supported by an earlier version of Internet Explorer. You can do this by serving the page with an x-ua-compatible header. For more info, see Specifying legacy document modes.
- https://msdn.microsoft.com/library/cc288325
Thus this tag is used to future proof the webpage, such that the older / compatible engine is used to render it the same way as intended by the creator.
Make sure that you have checked it to work properly with the IE version you specify.
Usage:
select replace_foreign_key('user_rates_posts', 'post_id', 'ON DELETE CASCADE');
Function:
CREATE OR REPLACE FUNCTION
replace_foreign_key(f_table VARCHAR, f_column VARCHAR, new_options VARCHAR)
RETURNS VARCHAR
AS $$
DECLARE constraint_name varchar;
DECLARE reftable varchar;
DECLARE refcolumn varchar;
BEGIN
SELECT tc.constraint_name, ccu.table_name AS foreign_table_name, ccu.column_name AS foreign_column_name
FROM
information_schema.table_constraints AS tc
JOIN information_schema.key_column_usage AS kcu
ON tc.constraint_name = kcu.constraint_name
JOIN information_schema.constraint_column_usage AS ccu
ON ccu.constraint_name = tc.constraint_name
WHERE constraint_type = 'FOREIGN KEY'
AND tc.table_name= f_table AND kcu.column_name= f_column
INTO constraint_name, reftable, refcolumn;
EXECUTE 'alter table ' || f_table || ' drop constraint ' || constraint_name ||
', ADD CONSTRAINT ' || constraint_name || ' FOREIGN KEY (' || f_column || ') ' ||
' REFERENCES ' || reftable || '(' || refcolumn || ') ' || new_options || ';';
RETURN 'Constraint replaced: ' || constraint_name || ' (' || f_table || '.' || f_column ||
' -> ' || reftable || '.' || refcolumn || '); New options: ' || new_options;
END;
$$ LANGUAGE plpgsql;
Be aware: this function won't copy attributes of initial foreign key. It only takes foreign table name / column name, drops current key and replaces with new one.
For Angular 2 - 5 refer the article Multiple Environment in angular
For Angular 6 use ng serve --configuration=dev
Note: Refer the same article for angular 6 as well. But wherever you find
--env
instead use--configuration
. That's works well for angular 6.

One of the easiest ways is to convert to Array:
for(int i = 0; i < set.size(); i++) {
System.out.println(set.toArray()[i]);
}
Extract the package to C:\ from here and install it
Copy the path C:\MinGW\bin
which contains gcc.exe.
go to Control Panel->System->Advanced>Environment variables
, and add or modify PATH. (just concatenate with ';')
Then, open a cmd.exe command prompt
(Windows + R and type cmd, if already opened, please close and open a new one, to get the path change)
change the folder to your file path by cd D:\c code Path
type gcc main.c -o helloworld.o
. It will compile the code. for C++ use g++
7 type ./helloworld
to run the program.
If zlib1.dll is missing, download from here
You can use int()
function to convert float64
type data to an int
. Similarly you can use float64()
Example:
func check(n int) bool {
// count the number of digits
var l int = countDigit(n)
var dup int = n
var sum int = 0
// calculates the sum of digits
// raised to power
for dup > 0 {
**sum += int(math.Pow(float64(dup % 10), float64(l)))**
dup /= 10
}
return n == sum
}
Another option would be to check the error code generated using try-catch block and first catching a WebException.
In my case, the error code was "SendFailure" because of certificate issue on HTTPS url, once I hit HTTP, that got resolved.
in Mac Remove Java Version using this 3 Commands
java -version
sudo rm -rf /Library/Java/*
sudo rm -rf /Library/PreferencePanes/Java*
sudo rm -rf /Library/Internet\ Plug-Ins/Java*
Run
java -version
//See java was successfully uninstalled.
java -version sudo rm -rf /Library/Java/* sudo rm -rf /Library/PreferencePanes/Java* sudo rm -rf /Library/Internet\ Plug-Ins/Java*
Run java -version

You can get rid of the first line. You don't need import java.lang.*;
Just change your 5th line to:
public static void main(String [] args) throws Exception
Reloading existing classes with existing data is likely to break things.
You can load new code into new class loaders relatively easily:
ClassLoader loader = URLClassLoader.newInstance(
new URL[] { yourURL },
getClass().getClassLoader()
);
Class<?> clazz = Class.forName("mypackage.MyClass", true, loader);
Class<? extends Runnable> runClass = clazz.asSubclass(Runnable.class);
// Avoid Class.newInstance, for it is evil.
Constructor<? extends Runnable> ctor = runClass.getConstructor();
Runnable doRun = ctor.newInstance();
doRun.run();
Class loaders no longer used can be garbage collected (unless there is a memory leak, as is often the case with using ThreadLocal, JDBC drivers, java.beans
, etc).
If you want to keep the object data, then I suggest a persistence mechanism such as Serialisation, or whatever you are used to.
Of course debugging systems can do fancier things, but are more hacky and less reliable.
It is possible to add new classes into a class loader. For instance, using URLClassLoader.addURL
. However, if a class fails to load (because, say, you haven't added it), then it will never load in that class loader instance.
Use numpy.asarray
:
import numpy as np
myarray = np.asarray(mylist)
This should give what you want:
FLOOR(RAND() * 401) + 100
Generically, FLOOR(RAND() * (<max> - <min> + 1)) + <min>
generates a number between <min
> and <max>
inclusive.
Update
This full statement should work:
SELECT name, address, FLOOR(RAND() * 401) + 100 AS `random_number`
FROM users
No one is talking about Linux but all above answers will work. Just use Ctrl to select more than one file. If you are looking to compare side by side, Meld is lovely.
The best way to fix it I have looked for the code or trick how to center nav menu and found the real solutions it works for all browsers and for my friends ;)
Here is how I have done:
body {
margin: 0;
padding: 0;
}
div maincontainer {
margin: 0 auto;
width: ___px;
text-align: center;
}
ul {
margin: 0;
padding: 0;
}
ul li {
margin-left: auto;
margin-right: auto;
}
and do not forget to set doctype html5

If it was mine I'd wrap the choruses and verses in XML elements as well.
I have thesame issue before but i solved it easily by just following this steps:
*connect your android phone in a debugging mode (to enable debugging mode goto settings scroll down About Phone scroll down tap seven times Build Number and it will automatically enable developer option turn on developer options and check USB debugging)
download Universal ADB Driver Installer
*choose Adb Driver Installer (Universal)
*install it *it will automatically detect your android device(any kind of brand) *chose the device and install
In version 0.2.13, You should be able to pass objects into $state.go,
$state.go('myState', {myParam: {some: 'thing'}})
$stateProvider.state('myState', {
url: '/myState/{myParam:json}',
params: {myParam: null}, ...
and then access the parameter in your controller.
$stateParams.myParam //should be {some: 'thing'}
myParam will not show up in the URL.
Source:
See the comment by christopherthielen https://github.com/angular-ui/ui-router/issues/983, reproduced here for convenience:
christopherthielen: Yes, this should be working now in 0.2.13.
.state('foo', { url: '/foo/:param1?param2', params: { param3: null } // null is the default value });
$state.go('foo', { param1: 'bar', param2: 'baz', param3: { id: 35, name: 'what' } });
$stateParams in 'foo' is now { param1: 'bar', param2: 'baz', param3: { id: 35, name: 'what' } }
url is /foo/bar?param2=baz.
var match=Regex.Match(@"a99b",@"\d+");
if(match.Success)
{
int val;
if(int.TryParse(match.Value,out val))

String text = "text";
text += new String(" ");
In fact, you don't even need to iterate over the iterable if it already comprehends some kind of mapping, the dict constructor doing it graciously for you:
>>> ts = [(1, 2), (3, 4), (5, 6)]
>>> dict(ts)
{1: 2, 3: 4, 5: 6}
>>> gen = ((i, i+1) for i in range(1, 6, 2))
>>> gen
<generator object <genexpr> at 0xb7201c5c>
>>> dict(gen)
{1: 2, 3: 4, 5: 6}
//Do it like---
function dragStart(this_,event) {
var row=$(this_).attr('whatever');
event.dataTransfer.setData("Text", row);
}
I have experienced same problem with System.Data.SQLite. The source of the problem is the dll you have used should have same .NET version with your project.
For example if you have used (in my case) SQLite for .NET 4.5, your platform target should be .NET 4.5 too.
You can find platform target by: Project > (project name) Properties > Build.

Use GregorianCalendar
. Set the date of the object, and then use getActualMaximum(Calendar.DAY_IN_MONTH)
.
http://docs.oracle.com/javase/7/docs/api/java/util/GregorianCalendar.html#getActualMaximum%28int%29 (but it was the same in Java 1.4)
