For the new Criteria since version Hibernate 5.2:
CriteriaBuilder criteriaBuilder = getSession().getCriteriaBuilder();
CriteriaQuery<SomeClass> criteriaQuery = criteriaBuilder.createQuery(SomeClass.class);
Root<SomeClass> root = criteriaQuery.from(SomeClass.class);
Path<Object> expressionA = root.get("A");
Path<Object> expressionB = root.get("B");
Predicate predicateAEqualX = criteriaBuilder.equal(expressionA, "X");
Predicate predicateBInXY = expressionB.in("X",Y);
Predicate predicateLeft = criteriaBuilder.and(predicateAEqualX, predicateBInXY);
Predicate predicateAEqualY = criteriaBuilder.equal(expressionA, Y);
Predicate predicateBEqualZ = criteriaBuilder.equal(expressionB, "Z");
Predicate predicateRight = criteriaBuilder.and(predicateAEqualY, predicateBEqualZ);
Predicate predicateResult = criteriaBuilder.or(predicateLeft, predicateRight);
criteriaQuery
.select(root)
.where(predicateResult);
List<SomeClass> list = getSession()
.createQuery(criteriaQuery)
.getResultList();
Using an example data.frame and example function (just +1 to all values)
A <- function(x) x + 1
wifi <- data.frame(replicate(9,1:4))
wifi

#1 1 1 1 1 1 1 1 1 1
#2 2 2 2 2 2 2 2 2 2
#3 3 3 3 3 3 3 3 3 3
#4 4 4 4 4 4 4 4 4 4
data.frame(wifi[1:3], apply(wifi[4:9],2, A) )
#or
cbind(wifi[1:3], apply(wifi[4:9],2, A) )

I faced the issue, In my understanding, It is because of invalid combination of Android Studio And Gradle Plugin versions. I was using Gradle version 5.4.1 and Studio version 3.4, hence I updated the Android studio to 3.5 and the issue got resolved
You can try using string replace:
string = string.replace('\r', '').replace('\n', '')
Before using (strongly type html helper into view) this line
@Html.TextBoxFor(p => p.Product.Name)
You should include your model into you page for making strongly type view.
@model SampleModel
I did this method for in-depth navigation of a Json
def filter_dict(data: dict, extract):
try:
if isinstance(extract, list):
for i in extract:
result = filter_dict(data, i)
if result:
return result
keys = extract.split('.')
shadow_data = data.copy()
for key in keys:
if str(key).isnumeric():
key = int(key)
shadow_data = shadow_data[key]
return shadow_data
except IndexError:
return None
filter_dict(wjdata, 'data.current_condition.0.temp_C')

To create a group of inputs you can create a custom html element
window.customElements.define('radio-group', RadioGroup);
https://gist.github.com/robdodson/85deb2f821f9beb2ed1ce049f6a6ed47
to keep selected option in each group, you need to add name attribute to inputs in group, if you not add it then all is one group.
/*
If your delimiters are slash-based, escape it:
\/*
*
means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.
To clarify how the shebang line works for windows, from the 3.7 Python doc:
You could create a custom tag as such:
<html>
<head>
<style>
vr {
display: inline-block;
// This is where you'd set the ruler color
background-color: black;
// This is where you'd set the ruler width
width: 2px;
//this is where you'd set the spacing between the ruler and surrounding text
margin: 0px 5px 0px 5px;
height: 100%;
vertical-align: top;
}
</style>
</head>
<body>
this is text <vr></vr> more text
</body>
</html>
(If anyone knows a way that I could turn this into an "open-ended" tag, like <hr>
let me know and I will edit it in)
I have create Demo.exe using Eclipse RCP.
I have run Demo.exe using C-Drive to same error generate like...
Solution : You might changed your drive for example
C:\Demo.exe to D:\Demo.exe
Step 1 : First Copy/Cut your .exe file like C:\Demo.exe
Step 2 : After Paste another drive like D:\Demo.exe
After executable file launching successfully.
I hope my answer is useful.
Just add:
import os
in the beginning, before:
from settings import PROJECT_ROOT
This will import the python's module os, which apparently is used later in the code of your module without being imported.
Use Strict is used to show common and repeated errors so that it is handled differently , and changes the way java script runs , such changes are :
Prevents accidental globals
No duplicates
Eliminates with
Eliminates this coercion
Safer eval()
Errors for immutables
you can also read this article for the details
You could also use Rails' with_indifferent_access
method so you could access the body with either symbols or strings.
value = '{"val":"test","val1":"test1","val2":"test2"}'
json = JSON.parse(value).with_indifferent_access
then
json[:val] #=> "test"
json["val"] #=> "test"
You had a mistake on the statement below. Use . not ,
echo '<img src="', $dir, '/', $file, '" alt="', $file, $
to
echo '<img src="'. $dir. '/'. $file. '" alt="'. $file. $
and
echo 'Directory \'', $dir, '\' not found!';
to
echo 'Directory \''. $dir. '\' not found!';
To expand on Jon Skeets answer the code for this in .Net 4
is:
string myCommaSeperatedString = string.Join(",",ls);
I'm some years late to the party here but I hit the same exception while trying to get Hibernate 3.5.1 working with HSQLDB and a desktop JavaFX program. I got it to work with the help of this thread and a lot of trial and error. It seems you get this error for a whole variety of problems:
No Persistence provider for EntityManager named mick
I tried building the hibernate tutorial examples but because I was using Java 10 I wasn't able to get them to build and run easily. I gave up on that, not really wanting to waste time fixing its problems. Setting up a module-info.java file (Jigsaw) is another hairball many people haven't discovered yet.
Somewhat confusing is that these (below) were the only two files I needed in my build.gradle file. The Hibernate documentation isn't clear about exactly which Jars you need to include. Entity-manager was causing confusion and is no longer required in the latest Hibernate version, and neither is javax.persistence-api. Note, I'm using Java 10 here so I had to include the jaxb-api, to get around some xml-bind errors, as well as add an entry for the java persistence module in my module-info.java file.
Build.gradle
// https://mvnrepository.com/artifact/org.hibernate/hibernate-core
compile('org.hibernate:hibernate-core:5.3.1.Final')
// https://mvnrepository.com/artifact/javax.xml.bind/jaxb-api
compile group: 'javax.xml.bind', name: 'jaxb-api', version: '2.3.0'
Module-info.java
// Used for HsqlDB - add the hibernate-core jar to build.gradle too
requires java.persistence;
With hibernate 5.3.1 you don't need to specify the provider, below, in your persistence.xml file. If one is not provided the Hibernate provider is chosen by default.
<provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
The persistence.xml file should be located in the correct directory so:
src/main/resources/META-INF/persistence.xml
Stepping through the hibernate source code in the Intellij debugger, where it checks for a dialect, also threw the exact same exception, because of a missing dialect property in the persistence.xml file. I added this (add the correct one for your DB type):
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
I still got the same exception after this, so stepping through the debugger again in Intellij revealed the test entity I was trying to persist (simple parent-child example) had missing annotations for the OneToMany, ManyToOne relationships. I fixed this and the exception went away and my entities were persisted ok.
Here's my full final persistence.xml:

I probably wasted about half a day on this gem. My advice would be to start very simple - a single test entity with one or two fields, as it seems like this exception can have many causes.
I had a problem, which appears just in internet explorer. Input field was styled
height:38px;
line-height:38px;
Unfortunately in IE the initial placeholder appears not at the correct position. But when I have clicked into the field and then left this field, the placeholder appeared on the right position.
My solution was to set:
line-height:normal;
No, there's no literal syntax for the empty set. You have to write set()
.
You can use PapaParse to help. https://www.papaparse.com/
Here is a CodePen. https://codepen.io/sandro-wiggers/pen/VxrxNJ
Papa.parse(e, {
header:true,
before: function(file, inputElem){ console.log('Attempting to Parse...')},
error: function(err, file, inputElem, reason){ console.log(err); },
complete: function(results, file){ $.PAYLOAD = results; }
});
Here is a function I use:
var map = new google.maps.Map(document.getElementById('map'), {
center: new google.maps.LatLng(52.2, 5),
mapTypeId: google.maps.MapTypeId.ROADMAP,
zoom: 7
});
function zoomTo(level) {
google.maps.event.addListener(map, 'zoom_changed', function () {
zoomChangeBoundsListener = google.maps.event.addListener(map, 'bounds_changed', function (event) {
if (this.getZoom() > level && this.initialZoom == true) {
this.setZoom(level);
this.initialZoom = false;
}
google.maps.event.removeListener(zoomChangeBoundsListener);
});
});
}
It's written as:
def my_function(self, param_one=None): # Or custom sentinel if None is vaild
if param_one is None:
param_one = self.one_of_the_vars
And I think it's safe to say that will never happen in Python due to the nature that self
doesn't really exist until the function starts... (you can't reference it, in its own definition - like everything else)
For example: you can't do d = {'x': 3, 'y': d['x'] * 5}
By default many profiles are defaulted to 0 core file size because the average user doesn't know what to do with them.
Try ulimit -c unlimited
before running your program.
Go to htdocs folder, right click, get info, click to unlock the padlock icon, type your password, under sharing permission change the priviledge for everyone to read & write, on the cog wheel button next to the + and - icons, click and select apply to all enclosed items, click to accept security request, close get info. Now xampp can write and read your root folder.
Note:
If you copy a new folder into the htdocs after this, you need to repeat the process for that folder to have write permission.
When you move your files to the live server, you need to also chmod the appropriate files & folders on the server as well.
If you have a Mac and not a English keyboard: Cmd-/ is still easy to produce.
Follow the below steps:
Whenever you want a Cmd-/, you have to change to the ABC keyboard (in your menu row at the top of your screen,if you have ticked it to be shown there in the System Settings - Keyboard tab
).
Cmd and the key to the left of the right "shift key
" gives you Cmd-/.
P.S: Don't forget to switch back to your normal keyboard.
Here is my code based on some answers here:
/**
* Checks if the phone is rooted.
*
* @return <code>true</code> if the phone is rooted, <code>false</code>
* otherwise.
*/
public static boolean isPhoneRooted() {
// get from build info
String buildTags = android.os.Build.TAGS;
if (buildTags != null && buildTags.contains("test-keys")) {
return true;
}
// check if /system/app/Superuser.apk is present
try {
File file = new File("/system/app/Superuser.apk");
if (file.exists()) {
return true;
}
} catch (Throwable e1) {
// ignore

I'm using PreviewKeyDown
private void _calendar_PreviewKeyDown(object sender, PreviewKeyDownEventArgs e){

The CScout refactoring browser can detect superfluous include directives in C (unfortunately not C++) code. You can find a description of how it works in this journal article.
static void PrintSmallestLargest(int[] arr)
{
if (arr.Length > 0)
{
int small = arr[0];
int large = arr[0];
for (int i = 0; i < arr.Length; i++)
{
if (large < arr[i])
{
int tmp = large;
large = arr[i];
arr[i] = large;
}
if (small > arr[i])
{
int tmp = small;
small = arr[i];
arr[i] = small;
}
}
Console.WriteLine("Smallest is {0}", small);
Console.WriteLine("Largest is {0}", large);
}
}
This way you can have smallest and largest number in a single loop.
Make sure your controller inherits from Controller
class.
It might even be crazier that stuff would work locally even without that.
Wrap it in <pre>
tags to preserve formatting.
for others there are a solution for any API level , you can place a item on top of each other example :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- my firt item with 4 corners radius(8dp)
-->
<item>
<shape>
<solid
android:angle="270.0"
android:color="#3D689A" />
<corners android:topLeftRadius="8dp" />
</shape>
</item>
<!-- my second item is on top right for a fake corner radius(0dp)
-->
<item
android:bottom="30dp"
android:left="50dp">
<shape>
<solid android:color="#5C83AF" />
</shape>
</item>
<!-- my third item is on bottom left for a fake corner radius(0dp)
-->
<item
android:right="50dp"
android:top="30dp">
<shape>
<solid android:color="#5C83AF" />
</shape>
</item>
</layer-list>
the result with light color to show you the three items :
the final result :
Best regards.
Add more than one class based on the condition:
<div ng-click="AbrirPopUp(s)"
ng-class="{'class1 class2 class3':!isNew,
'class1 class4': isNew}">{{ isNew }}</div>
Apply: class1 + class2 + class3 when isNew=false,
Apply: class1+ class4 when isNew=true
Try width: max-content
to adjust the width of the div by it's content.
<!DOCTYPE html>
<html>
<head>
<style>
div.ex1 {
width:500px;
margin: auto;
border: 3px solid #73AD21;
}
div.ex2 {
width: max-content;
margin: auto;
border: 3px solid #73AD21;
}
</style>
</head>
<body>
<div class="ex1">This div element has width 500px;</div>
<br>
<div class="ex2">Width by content size</div>

Use the time module:
epoch_time = int(time.time())
$(<img />).attr('src','http://somedomain.com/image.jpg');
Should be better than ajax because if its a gallery and you are looping through a list of pics, if the image is already in cache, it wont send another request to server. It will request in the case of jQuery/ajax and return a HTTP 304 (Not modified) and then use original image from cache if its already there. The above method reduces an empty request to server after the first loop of images in the gallery.

JSONP is really a simply trick to overcome XMLHttpRequest same domain policy. (As you know one cannot send AJAX (XMLHttpRequest) request to a different domain.)
So - instead of using XMLHttpRequest we have to use script HTMLl tags, the ones you usually use to load JS files, in order for JS to get data from another domain. Sounds weird?
Thing is - turns out script tags can be used in a fashion similar to XMLHttpRequest! Check this out:
script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://www.someWebApiServer.com/some-data";
You will end up with a script segment that looks like this after it loads the data:
<script>
{['some string 1', 'some data', 'whatever data']}
</script>
However this is a bit inconvenient, because we have to fetch this array from script tag. So JSONP creators decided that this will work better (and it is):
script = document.createElement("script");
script.type = "text/javascript";
script.src = "http://www.someWebApiServer.com/some-data?callback=my_callback";
Notice my_callback function over there? So - when JSONP server receives your request and finds callback parameter - instead of returning plain JS array it'll return this:
my_callback({['some string 1', 'some data', 'whatever data']});
See where the profit is: now we get automatic callback (my_callback) that'll be triggered once we get the data. That's all there is to know about JSONP: it's a callback and script tags.
NOTE:
These are simple examples of JSONP usage, these are not production ready scripts.
RAW JavaScript demonstration (simple Twitter feed using JSONP):
<html>
<head>
</head>
<body>
<div id = 'twitterFeed'></div>
<script>
function myCallback(dataWeGotViaJsonp){
var text = '';
var len = dataWeGotViaJsonp.length;
for(var i=0;i<len;i++){
twitterEntry = dataWeGotViaJsonp[i];
text += '<p><img src = "' + twitterEntry.user.profile_image_url_https +'"/>' + twitterEntry['text'] + '</p>'
}
document.getElementById('twitterFeed').innerHTML = text;
}
</script>
<script type="text/javascript" src="http://twitter.com/status/user_timeline/padraicb.json?count=10&callback=myCallback"></script>
</body>
</html>
Basic jQuery example (simple Twitter feed using JSONP):
<html>
<head>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
$.ajax({
url: 'http://twitter.com/status/user_timeline/padraicb.json?count=10',
dataType: 'jsonp',
success: function(dataWeGotViaJsonp){
var text = '';
var len = dataWeGotViaJsonp.length;
for(var i=0;i<len;i++){
twitterEntry = dataWeGotViaJsonp[i];
text += '<p><img src = "' + twitterEntry.user.profile_image_url_https +'"/>' + twitterEntry['text'] + '</p>'
}
$('#twitterFeed').html(text);
}
});
})
</script>
</head>
<body>
<div id = 'twitterFeed'></div>

</html>
JSONP stands for JSON with Padding. (very poorly named technique as it really has nothing to do with what most people would think of as “padding”.)
Try:
var Wrapper = React.createClass({
render: function() {
return (
<div className="wrapper">
before
{this.props.children}
after
</div>
);
}
});
See Multiple Components: Children and Type of the Children props in the docs for more info.
I use the timestamp
i.e
new File( simpleDateFormat.format( new Date() ) );
And have the simpleDateFormat initialized to something like as:
new SimpleDateFormat("File-ddMMyy-hhmmss.SSS.txt");
EDIT
What about
new File(String.format("%s.%s", sdf.format( new Date() ),
random.nextInt(9)));
Unless the number of files created in the same second is too high.
If that's the case and the name doesn't matters
new File( "file."+count++ );
:P
You should make a habit of looking at the documentation for stuff like this. It's very useful and will improve your skills very quickly. Here's the relevant bit when you do git help diff
git diff [options] [--no-index] [--] <path> <path>
The two <path>
s are what you need to change to the directories in question.
There are two problems in your code:
visibility
and not visiblity
..style
property.It's easy to fix. Simple replace this:
document.getElementById("remember").visiblity
with this:
document.getElementById("remember").style.visibility

Business Intelligence Development Studio is Microsoft Visual Studio 2008 with additional project types that are specific to SQL Server business intelligence. Business Intelligence Development Studio is the primary environment that you will use to develop business solutions that include Analysis Services, Integration Services, and Reporting Services projects. Each project type supplies templates for creating the objects required for business intelligence solutions, and provides a variety of designers, tools, and wizards to work with the objects.
If you already have Visual Studio installed, the new project types will be installed along with SQL Server.
These are configurable variables in php.ini:
; with sane limits
xdebug.var_display_max_depth = 10
xdebug.var_display_max_children = 256
xdebug.var_display_max_data = 1024
; with no limits
; (maximum nesting is 1023)
xdebug.var_display_max_depth = -1
xdebug.var_display_max_children = -1
xdebug.var_display_max_data = -1
Of course, these may also be set at runtime via ini_set()
, useful if you don't want to modify php.ini and restart your web server but need to quickly inspect something more deeply.
ini_set('xdebug.var_display_max_depth', '10');
ini_set('xdebug.var_display_max_children', '256');
ini_set('xdebug.var_display_max_data', '1024');
Xdebug settings are explained in the official documentation.
You can try this
$('div.easy_editor').css({'border-width':'9px', 'border-style':'solid', 'border-color':'red'});
The $('div.easy_editor')
refers to a collection of all divs that have the class easy editor already. There is no need to use each() unless there was some function that you wanted to run on each. The css() method actually applies to all the divs you find.
POM(Project Object Model) is nothing but the automation script for building the project,we can write the automation script in XML, the building script files are named diffrenetly in different Automation tools
like we call build.xml in ANT,pom.xml in MAVEN
MAVEN can packages jars,wars, ears and POM which new thing to all of us
if you want check WHAT IS POM.XML
One option is to put the character literally in your script, e.g.:
const omega = 'O';
This requires that you let the browser know the correct source encoding, see Unicode in JavaScript
However, if you can't or don't want to do this (e.g. because the character is too exotic and can't be expected to be available in the code editor font), the safest option may be to use new-style string escape or String.fromCodePoint
:
const omega = '\u{3a9}';
// or:
const omega = String.fromCodePoint(0x3a9);
This is not restricted to UTF-16 but works for all unicode code points. In comparison, the other approaches mentioned here have the following downsides:
const omega = 'Ω';
): only work when rendered unescaped in an HTML elementconst omega = '\u03A9';
): restricted to UTF-16String.fromCharCode
: restricted to UTF-16In addition to the answer, $ yarn cache clean
removes all libraries from cache. If you want to remove a specific lib's cache run $ yarn cache dir
to get the right yarn cache directory path for your OS, then $ cd
to that directory and remove the folder with the name
+ version
of the lib you want to cleanup.
You could use getdate() in a default as this SO question's accepted answer shows. This way you don't provide the date, you just insert the rest and that date is the default value for the column.
You could also provide it in the values list of your insert and do it manually if you wish.
Shouldnt we be using OG?
The chosen answer is good but doesn't work when a site is redirected (very common!), and doesn't return OG tags, which are the new industry standard. Here's a little function which is a bit more usable in 2018. It tries to get OG tags and falls back to meta tags if it cant them:
function getSiteOG( $url, $specificTags=0 ){
$doc = new DOMDocument();
@$doc->loadHTML(file_get_contents($url));
$res['title'] = $doc->getElementsByTagName('title')->item(0)->nodeValue;
foreach ($doc->getElementsByTagName('meta') as $m){
$tag = $m->getAttribute('name') ?: $m->getAttribute('property');
if(in_array($tag,['description','keywords']) || strpos($tag,'og:')===0) $res[str_replace('og:','',$tag)] = $m->getAttribute('content');
}
return $specificTags? array_intersect_key( $res, array_flip($specificTags) ) : $res;
}
How to use it:
/////////////
//SAMPLE USAGE:
print_r(getSiteOG("http://www.stackoverflow.com")); //note the incorrect url
/////////////
//OUTPUT:

A good answer was already posted, this is only a recommendation!
A good way would be to just add a category to NSManagedObject
and implement a method like I did:
Header File (e.g. NSManagedObject+Ext.h
)
@interface NSManagedObject (Logic)
+ (void) deleteAllFromEntity:(NSString*) entityName;
@end
Code File: (e.g. NSManagedObject+Ext.m)
@implementation NSManagedObject (Logic)
+ (void) deleteAllFromEntity:(NSString *)entityName {
NSManagedObjectContext *managedObjectContext = [AppDelegate managedObjectContext];
NSFetchRequest * allRecords = [[NSFetchRequest alloc] init];
[allRecords setEntity:[NSEntityDescription entityForName:entityName inManagedObjectContext:managedObjectContext]];
[allRecords setIncludesPropertyValues:NO];
NSError * error = nil;
NSArray * result = [managedObjectContext executeFetchRequest:allRecords error:&error];
for (NSManagedObject * profile in result) {
[managedObjectContext deleteObject:profile];
}
NSError *saveError = nil;
[managedObjectContext save:&saveError];
}
@end
... the only thing you have to is to get the managedObjectContext from the app delegate, or where every you have it in ;)
afterwards you can use it like:
[NSManagedObject deleteAllFromEntity:@"EntityName"];
one further optimization could be that you remove the parameter for tha entityname and get the name instead from the clazzname. this would lead to the usage:
[ClazzName deleteAllFromEntity];
a more clean impl (as category to NSManagedObjectContext):
@implementation NSManagedObjectContext (Logic)
- (void) deleteAllFromEntity:(NSString *)entityName {
NSFetchRequest * allRecords = [[NSFetchRequest alloc] init];
[allRecords setEntity:[NSEntityDescription entityForName:entityName inManagedObjectContext:self]];
[allRecords setIncludesPropertyValues:NO];
NSError * error = nil;
NSArray * result = [self executeFetchRequest:allRecords error:&error];
for (NSManagedObject * profile in result) {
[self deleteObject:profile];
}
NSError *saveError = nil;
[self save:&saveError];
}
@end
The usage then:
[managedObjectContext deleteAllFromEntity:@"EntityName"];
Uhm, what's wrong with this:
#include <iostream>
using namespace std;
int main(int, char **)
{
char c = 'A';
int x = c; // Look ma! No cast!
cout << "The character '" << c << "' has an ASCII code of " << x << endl;
return 0;
}
This solution does not require anchor tags but you do of course need to match the menu button (arbitrary attribute, 'ss' in example) with the destination element id in your html.
ss="about"
takes you to id="about"

Nothing printed. The argument must be a pointer to a signed int, where the number of characters written so far is stored.
#include <stdio.h>
int main()
{
int val;
printf("blah %n blah\n", &val);
printf("val = %d\n", val);
return 0;
}
The previous code prints:
blah blah
val = 5
Adding two more solutions to the problem:
#! c:\[path to Python 2.5]\python.exe
- for scripts you want to be run with Python 2.5
#! c:\[path to Python 2.6]\python.exe
- for scripts you want to be run with Python 2.6
or instead of running python
command run pylauncher command (py
) specyfing which version of Python you want;
py -2.6
– version 2.6
py -2
– latest installed version 2.x
py -3.4
– version 3.4
py -3
– latest installed version 3.x
virtualenv -p c:\[path to Python 2.5]\python.exe [path where you want to have virtualenv using Python 2.5 created]\[name of virtualenv]
virtualenv -p c:\[path to Python 2.6]\python.exe [path where you want to have virtualenv using Python 2.6 created]\[name of virtualenv]
for example
virtualenv -p c:\python2.5\python.exe c:\venvs\2.5
virtualenv -p c:\python2.6\python.exe c:\venvs\2.6
then you can activate the first and work with Python 2.5 like this
c:\venvs\2.5\activate
and when you want to switch to Python 2.6 you do
deactivate
c:\venvs\2.6\activate
Sometimes your SVG will be inlined by React so you need quotes around it:

otherwise it's invalid CSS and the browser dev tools will not show that you've set background-image at all.
Call JObject's ToString(Formatting.None)

Alternatively if you pass the object to the JsonConvert.SerializeObject method it will return the JSON without formatting.

Solution 1:
Go to your android folder > Gradle.properties > add your jdk path.
Clean and rebuild then it is done. // For Example Purpose Only
org.gradle.java.home=/Library/Java/JavaVirtualMachines/jdk1.8.0_251.jdk/Contents/Home
Solution 2 At last, here I found the solution.
Add jdk path
to gradle.properties file and did a rebuild.
This will also solve your error.
Here is all Solution could not find tools.jar
Both your examples are equivalent. However, the first one is less obvious and more "hacky", while the second one clearly states your intention.
int (*pointer)[280];
pointer = tab1;
pointer
points to an 1D array of 280 integers. In your assignment, you actually assign the first row of tab1
. This works since you can implicitly cast arrays to pointers (to the first element).
When you are using pointer[5][12]
, C treats pointer
as an array of arrays (pointer[5]
is of type int[280]
), so there is another implicit cast here (at least semantically).
In your second example, you explicitly create a pointer to a 2D array:
int (*pointer)[100][280];
pointer = &tab1;
The semantics are clearer here: *pointer
is a 2D array, so you need to access it using (*pointer)[i][j]
.
Both solutions use the same amount of memory (1 pointer) and will most likely run equally fast. Under the hood, both pointers will even point to the same memory location (the first element of the tab1
array), and it is possible that your compiler will even generate the same code.
The first solution is "more advanced" since one needs quite a deep understanding on how arrays and pointers work in C to understand what is going on. The second one is more explicit.
^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=)?$
This one is good, but will match an empty String
This one does not match empty string :
^(?:[A-Za-z0-9+/]{4})*(?:[A-Za-z0-9+/]{2}==|[A-Za-z0-9+/]{3}=|[A-Za-z0-9+/]{4})$
Use file
. Examples:
> file --mime-type image.png
image.png: image/png
> file -b --mime-type image.png
image/png
> file -i FILE_NAME
image.png: image/png; charset=binary
A slight generalization to Peter's answer -- you can specify a range over the original array's shape if you want to go beyond three dimensional arrays.
e.g. to flatten all but the last two dimensions:
arr = numpy.zeros((3, 4, 5, 6))
new_arr = arr.reshape(-1, *arr.shape[-2:])
new_arr.shape
# (12, 5, 6)
EDIT: A slight generalization to my earlier answer -- you can, of course, also specify a range at the beginning of the of the reshape too:
arr = numpy.zeros((3, 4, 5, 6, 7, 8))
new_arr = arr.reshape(*arr.shape[:2], -1, *arr.shape[-2:])
new_arr.shape
# (3, 4, 30, 7, 8)
The purpose is typically just to restrict the scope of the nested class. Nested classes compared to normal classes have the additional possibility of the private
modifier (as well as protected
of course).
Basically, if you only need to use this class from within the "parent" class (in terms of scope), then it is usually appropiate to define it as a nested class. If this class might need to be used from without the assembly/library, then it is usually more convenient to the user to define it as a separate (sibling) class, whether or not there is any conceptual relationship between the two classes. Even though it is technically possible to create a public
class nested within a public
parent class, this is in my opinion rarely an appropiate thing to implement.
Open task manager and kill adb.exe, now adb will start normally
Get each bit of byte and convert to string. Say byte has 8 bits, and we can get them one by one via bit move. For example, we move the second bit of the byte 6 bits to right, the second bit at last of bit of 8 bits, then and(&) with 0x0001 to clean the front bits.
public static String getByteBinaryString(byte b) {
StringBuilder sb = new StringBuilder();
for (int i = 7; i >= 0; --i) {
sb.append(b >>> i & 1);
}
return sb.toString();
}

The .load("file.txt")
is much easier. Which works but even if testing, you won't get results from a localdrive, you'll need an actual http server. The invisible error is an XMLHttpRequest
error.
Since Python 2.6.X you might want to use:
"my {0} string: {1}".format("cool", "Hello there!")
Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.
You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.
But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.
You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.
If you want that warm and fuzzy feeling just go with with.

So not much of a difference.

if you don't want or need a typed object try:
using Newtonsoft.Json;
// ...
dynamic json = JsonConvert.DeserializeObject(str);
or try for a typed object try:
Foo json = JsonConvert.DeserializeObject<Foo>(str)
Using Guava (r07) you can do this:
for(char c : Lists.charactersOf(someString)) { ... }
This has the convenience of using foreach while not copying the string to a new array. Lists.charactersOf
returns a view of the string as a List
.

NumPy is slower because it casts the input to boolean values (so None and 0 becomes False and everything else becomes True).
import pandas as pd
import numpy as np
s = pd.Series([True, None, False, True])
np.logical_not(s)
gives you
0 False
1 True
2 True
3 False
dtype: object
whereas ~s would crash. In most cases tilde would be a safer choice than NumPy.

I created a module to make dealing with trusted hosts slightly easier, psTrustedHosts. You can find the repo here on GitHub. It provides four functions that make working with trusted hosts easy: Add-TrustedHost
, Clear-TrustedHost
, Get-TrustedHost
, and Remove-TrustedHost
. You can install the module from PowerShell Gallery with the following command:
Install-Module psTrustedHosts -Force
In your example, if you wanted to append hosts 'machineC' and 'machineD' you would simply use the following command:
Add-TrustedHost 'machineC','machineD'
To be clear, this adds hosts 'machineC' and 'machineD' to any hosts that already exist, it does not overwrite existing hosts.
The Add-TrustedHost
command supports pipeline processing as well (so does the Remove-TrustedHost
command) so you could also do the following:
'machineC','machineD' | Add-TrustedHost
I have been using USysWare DPack since forever. It is very small and not intrusive so if all you want is a quick shortcut window showing list of methods of the current file you are using, it provides just that. Good thing is that the author is still active after more than 10 years just to keep providing the same features into latest VS release.
https://marketplace.visualstudio.com/items?itemName=SergeyM.DPack-16348
After installation, just use Alt + M
to bring up the method list window. I prefer to show all members instead, but it's up to you.
Like this:
import java.util.*;
Set<Integer> a = new HashSet<Integer>();
a.add( 1);
a.add( 2);
a.add( 3);
Or adding from an Array/ or multiple literals; wrap to a list, first.
Integer[] array = new Integer[]{ 1, 4, 5};
Set<Integer> b = new HashSet<Integer>();
b.addAll( Arrays.asList( b)); // from an array variable
b.addAll( Arrays.asList( 8, 9, 10)); // from literals
To get the intersection:
// copies all from A; then removes those not in B.
Set<Integer> r = new HashSet( a);
r.retainAll( b);
// and print; r.toString() implied.
System.out.println("A intersect B="+r);
Hope this answer helps. Vote for it!
Here is the solution:
use Illuminate\Support\Facades\Hash;
$password = request('password'); // get the value of password field
$hashed = Hash::make($password); // encrypt the password
N.B: Use 1st line code at the very beginning in your controller. Last but not the least, use the rest two lines of code inside the function of your controller where you want to manipulate with data after the from is submitted. Happy coding :)
I used this command to find last 5 minutes logs for particular event "DHCPACK

In C++
Any variable at file scope and that is not nested inside a class or function, is visible throughout all translation units in a program. This is called external linkage because at link time the name is visible to the linker everywhere, external to that translation unit.
Global variables and ordinary functions have external linkage.
Static object or function name at file scope is local to translation unit. That is called as Internal Linkage
Linkage refers only to elements that have addresses at link/load time; thus, class declarations and local variables have no linkage.
You can also use "shouldReceiveTouch" method of UIGestureRecognizer
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch: (UITouch *)touch {
UIView *view = touch.view;
NSLog(@"%d", view.tag);
}
Dont forget to set delegate of your gesture recognizer.
It is very simple.
select DATENAME(month, getdate())
output : January
>>> import numpy as np
>>> a = np.random.randint(0, 5, size=(5, 4))
>>> a
array([[4, 2, 1, 1],
[3, 0, 1, 2],
[2, 0, 1, 1],
[4, 0, 2, 3],
[0, 0, 0, 2]])
>>> b = a < 3
>>> b
array([[False, True, True, True],
[False, True, True, True],
[ True, True, True, True],
[False, True, True, False],
[ True, True, True, True]], dtype=bool)
>>>
>>> c = b.astype(int)
>>> c
array([[0, 1, 1, 1],
[0, 1, 1, 1],
[1, 1, 1, 1],
[0, 1, 1, 0],
[1, 1, 1, 1]])
You can shorten this with:
>>> c = (a < 3).astype(int)
The following query is very helpful
select * from
(select count(*) used from pg_stat_activity) q1,
(select setting::int res_for_super from pg_settings where name=$$superuser_reserved_connections$$) q2,
(select setting::int max_conn from pg_settings where name=$$max_connections$$) q3;
You can copy an object to your clip board using copy(JSON.stringify(Object_Name)); in the console.
Eg:- Copy & Paste the below code in your console and press ENTER. Now, try to paste(CTRL+V for Windows or CMD+V for mac) it some where else and you will get {"name":"Daniel","age":25}
var profile = {
name: "Daniel",
age: 25
};
copy(JSON.stringify(profile));
You could use Enumerable.Max
:
new [] { 1, 2, 3 }.Max();
Unless you are forced to use C, you should never use malloc
. Always use new
.
If you need a big chunk of data just do something like:
char *pBuffer = new char[1024];
Be careful though this is not correct:
//This is incorrect - may delete only one element, may corrupt the heap, or worse...
delete pBuffer;
Instead you should do this when deleting an array of data:
//This deletes all items in the array
delete[] pBuffer;
The new
keyword is the C++ way of doing it, and it will ensure that your type will have its constructor called. The new
keyword is also more type-safe whereas malloc
is not type-safe at all.
The only way I could think that would be beneficial to use malloc
would be if you needed to change the size of your buffer of data. The new
keyword does not have an analogous way like realloc
. The realloc
function might be able to extend the size of a chunk of memory for you more efficiently.
It is worth mentioning that you cannot mix new
/free
and malloc
/delete
.
Note: Some answers in this question are invalid.
int* p_scalar = new int(5); // Does not create 5 elements, but initializes to 5
int* p_array = new int[5]; // Creates 5 elements
I think this is a solution that solves your problem easily: (return true if any of the parameters is not null)
public boolean isUserEmpty(){
boolean isEmpty;
isEmpty = isEmpty = Stream.of(id,
name)
.anyMatch(userParameter -> userParameter != null);
return isEmpty;}
Another solution to the same task is:(you can change it to if(isEmpty==0) checks if all the parameters are null.
public boolean isUserEmpty(){
long isEmpty;
isEmpty = Stream.of(id,
name)
.filter(userParameter -> userParameter != null).count();
if (isEmpty > 0) {
return true;
} else {
return false;
}
}

Tomcat can tell you in several ways. Here's the easiest:
$ /path/to/catalina.sh version
Using CATALINA_BASE: /usr/local/apache-tomcat-7.0.29
Using CATALINA_HOME: /usr/local/apache-tomcat-7.0.29
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.29/temp
Using JRE_HOME: /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/Home
Using CLASSPATH: /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar
Server version: Apache Tomcat/7.0.29
Server built: Jul 3 2012 11:31:52
Server number: 7.0.29.0
OS Name: Mac OS X
OS Version: 10.7.4
Architecture: x86_64
JVM Version: 1.6.0_33-b03-424-11M3720
JVM Vendor: Apple Inc.
If you don't know where catalina.sh
is (or it never gets called), you can usually find it via ps
:
$ ps aux | grep catalina
chris 930 0.0 3.1 2987336 258328 s000 S Wed01PM 2:29.43 /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/java -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.library.path=/usr/local/apache-tomcat-7.0.29/lib -Djava.endorsed.dirs=/usr/local/apache-tomcat-7.0.29/endorsed -classpath /usr/local/apache-tomcat-7.0.29/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.29/bin/tomcat-juli.jar -Dcatalina.base=/Users/chris/blah/blah -Dcatalina.home=/usr/local/apache-tomcat-7.0.29 -Djava.io.tmpdir=/Users/chris/blah/blah/temp org.apache.catalina.startup.Bootstrap start
From the ps
output, you can see both catalina.home
and catalina.base
. catalina.home
is where the Tomcat base files are installed, and catalina.base
is where the running configuration of Tomcat exists. These are often set to the same value unless you have configured your Tomcat for multiple (configuration) instances to be launched from a single Tomcat base install.
You can also interrogate the JVM directly if you can't find it in a ps
listing:
$ jinfo -sysprops 930 | grep catalina
Attaching to process ID 930, please wait...
Debugger attached successfully.
Server compiler detected.
JVM version is 20.8-b03-424
catalina.base = /Users/chris/blah/blah
[...]
catalina.home = /usr/local/apache-tomcat-7.0.29
If you can't manage that, you can always try to write a JSP that dumps the values of the two system properties catalina.home
and catalina.base
.
For those finding this question in dotnet core. I found a solution here

Hold down the Option key and click where you'd like the cursor to move, and Terminal rushes the cursor that precise spot.
The biggest reason that you use LEA
over a MOV
is if you need to perform arithmetic on the registers that you are using to calculate the address. Effectively, you can perform what amounts to pointer arithmetic on several of the registers in combination effectively for "free."
What's really confusing about it is that you typically write an LEA
just like a MOV
but you aren't actually dereferencing the memory. In other words:
MOV EAX, [ESP+4]
This will move the content of what ESP+4
points to into EAX
.
LEA EAX, [EBX*8]
This will move the effective address EBX * 8
into EAX, not what is found in that location. As you can see, also, it is possible to multiply by factors of two (scaling) while a MOV
is limited to adding/subtracting.
In addition to the other answer, I would like to point out that this reasoning is also known as the De Morgan's law. It's actually more about mathematics than programming, but it is so fundamental that every programmer should know about it.
Your problem started like this:
enabled = A and B
disabled = not ( A and B )
So far so good, but you went one step further and tried to remove the braces.
And that's a little tricky, because you have to replace the and
/&&
with an or
/||
.
not ( A and B ) = not(A) OR not(B)
Or in a more mathematical notation:
I always keep this law in mind whenever I simplify conditions or work with probabilities.
Use an interpolated string, this generates a rounded up string:
var strlen = 6;
$"{48.485:F2}"
Output
"48.49"

For those who are unable to resolve with above method
Go to project settings in Xcode. Menu File->Project Settings
Go to per-User Project Settings section.
Click on advanced.
Select Xcode Default option. previously this used to be Legacy for my project.
I have analysed on similar lines and concluded that clean is causing the archive to fail. So, the new build system is not clearing the custom/legacy build directory.
delete the build/ folder in ios/ and rerun if that doesn't do any change then
File -> Project Settings (or WorkSpace Settings) -> Build System -> Legacy Build System
Rerun and voilà!
If it still Fails you need to clean full project
Do the following:
npm cache clean --force
react-native eject
npm install
react-native link
react-native run-ios
Yes, from the moment on you establish a HTTPS connection everyting is secure. The query string (GET) as the POST is sent over SSL.
Here is a code with some minor modification in Bourne's answer. As JSON.parse(number) works fine without any exception so added isNaN.
function isJson(str) {
try {
JSON.parse(str);
} catch (e) {
return false;
}
return isNaN(str);
}
an alternative would be to do something like:
SELECT
CAST(P0.seconds as bigint) as seconds
FROM
(
SELECT
seconds
FROM
TableName
WHERE
ISNUMERIC(seconds) = 1
) P0

They appear to be the same... Documentation from the click() function:
This method is a shortcut for .bind('click', handler)
Documentation from the on() function:
As of jQuery 1.7, the .on() method provides all functionality required for attaching event handlers. For help in converting from older jQuery event methods, see .bind(), .delegate(), and .live(). To remove events bound with .on(), see .off().
There are two reasons why json.Decoder
should be preferred over json.Unmarshal
- that are not addressed in the most popular answer from 2013:
go 1.10
introduced a new method json.Decoder.DisallowUnknownFields() which addresses the concern of detecting unwanted JSON-inputreq.Body
is already an io.Reader
. Reading its entire contents and then performing json.Unmarshal
wastes resources if the stream was, say a 10MB block of invalid JSON. Parsing the request body, with json.Decoder
, as it streams in would trigger an early parse error if invalid JSON was encountered. Processing I/O streams in realtime is the preferred go-way. Addressing some of the user comments about detecting bad user input:
To enforce mandatory fields, and other sanitation checks, try:
d := json.NewDecoder(req.Body)
d.DisallowUnknownFields() // catch unwanted fields
// anonymous struct type: handy for one-time use
t := struct {
Test *string `json:"test"` // pointer so we can test for field absence
}{}
err := d.Decode(&t)
if err != nil {
// bad JSON or unrecognized json field
http.Error(rw, err.Error(), http.StatusBadRequest)
return
}
if t.Test == nil {
http.Error(rw, "missing field 'test' from JSON object", http.StatusBadRequest)
return
}
// optional extra check
if d.More() {
http.Error(rw, "extraneous data after JSON object", http.StatusBadRequest)
return
}
// got the input we expected: no more, no less
log.Println(*t.Test)
Typical output:
$ curl -X POST -d "{}" http://localhost:8082/strict_test
expected json field 'test'
$ curl -X POST -d "{\"Test\":\"maybe?\",\"Unwanted\":\"1\"}" http://localhost:8082/strict_test
json: unknown field "Unwanted"
$ curl -X POST -d "{\"Test\":\"oops\"}g4rB4g3@#$%^&*" http://localhost:8082/strict_test
extraneous data after JSON
$ curl -X POST -d "{\"Test\":\"Works\"}" http://localhost:8082/strict_test

I've had success with the following code. Albeit it got me a single lock for some reason (even if I've tried different LatLng pairs), it worked for me. mLocationManager
is a LocationManager
which is hooked up to a LocationListener
:
private void getMockLocation()
{
mLocationManager.removeTestProvider(LocationManager.GPS_PROVIDER);
mLocationManager.addTestProvider
(
LocationManager.GPS_PROVIDER,
"requiresNetwork" == "",
"requiresSatellite" == "",
"requiresCell" == "",
"hasMonetaryCost" == "",
"supportsAltitude" == "",
"supportsSpeed" == "",
"supportsBearing" == "",
android.location.Criteria.POWER_LOW,
android.location.Criteria.ACCURACY_FINE
);
Location newLocation = new Location(LocationManager.GPS_PROVIDER);
newLocation.setLatitude (/* TODO: Set Some Lat */);
newLocation.setLongitude(/* TODO: Set Some Lng */);
newLocation.setAccuracy(500);
mLocationManager.setTestProviderEnabled
(
LocationManager.GPS_PROVIDER,
true
);
mLocationManager.setTestProviderStatus
(
LocationManager.GPS_PROVIDER,
LocationProvider.AVAILABLE,
null,
System.currentTimeMillis()
);
mLocationManager.setTestProviderLocation
(
LocationManager.GPS_PROVIDER,
newLocation
);
}
I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:
GET approach with JSON result
curl -i -H "Accept: application/json" http://someHostName/someEndpoint | grep }| python -mjson.tool
POST approach with JSON result
curl -X POST -H "Accept: Application/json" -H "Content-Type: application/json" http://someHostName/someEndpoint -d '{"id":"IDVALUE","name":"Mike"}' | grep }| python -mjson.tool
Applying a selector from the .nav-tabs seems to be working

<div class="tab-pane" id="aaa">...Content...</div>
<div class="tab-pane" id="bbb">...Content...</div>
<div class="tab-pane" id="ccc">...Content...</div>

instanceof
is used to check if an object is an instance of a class, an instance of a subclass, or an instance of a class that implements a particular interface.
Please check this link. Which will allow animations like L2R, R2L, T2B, B2T animations.
This code shows animation from left to right
TranslateAnimation animate = new TranslateAnimation(0,view.getWidth(),0,0);
animate.setDuration(500);
animate.setFillAfter(true);
view.startAnimation(animate);
view.setVisibility(View.GONE);
if you want to do it from R2L then use
TranslateAnimation animate = new TranslateAnimation(0,-view.getWidth(),0,0);
for top to bottom as
TranslateAnimation animate = new TranslateAnimation(0,0,0,view.getHeight());
and vice a versa..
If you want to match anything after a word stop an not only at the start of the line you may use : \bstop.*\b
- word followed by line
Or if you want to match the word in the string use \bstop[a-zA-Z]*
- only the words starting with stop
Or the start of lines with stop ^stop[a-zA-Z]*
for the word only - first word only
The whole line ^stop.*
- first line of the string only
And if you want to match every string starting with stop including newlines use : /^stop.*/s
- multiline string starting with stop
Setting the HttpWebRequest.KeepAlive

Since I was accessing a HTTPS page I had to set the Service Point Security Protocol to Tls12.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
Notice that there are other SecurityProtocolTypes
: SecurityProtocolType.Ssl3
, SecurityProtocolType.Tls
, SecurityProtocolType.Tls11
So if the Tls12 doesn't work for you, try the three remaining options.
Also notice that you can set multiple protocols. This is preferable on most cases.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
Edit: Since this is a choice of security standards it's obviously best to go with the latest (TLS 1.2 as of writing this), and not just doing what works. In fact, SSL3 has been officially prohibited from use since 2015 and TLS 1.0 and TLS 1.1 will likely be prohibited soon as well. source: @aske-b
I want to share my solution for those who are using react-router-dom v5
since none of these v4 solutions did the work for me.
What solved my problem was installing react-router-scroll-top and put the wrapper in the <App />
like this:
const App = () => (
<Router>
<ScrollToTop>
<App/>
</ScrollToTop>
</Router>
)
and that's it! it worked!

With:
global index_add_counter
You are not defining, just declaring so it's like saying there is a global index_add_counter
variable elsewhere, and not create a global called index_add_counter
. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global
keyword and initialize your variable:
index_add_counter = 0
Now you can import it with:
from app import index_add_counter
The construction:
global index_add_counter
is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:
index_add_counter = 0
def test():
global index_add_counter # means: in this scope, use the global name
print(index_add_counter)

I had a similar problem on OSX. It just so happens I had opened two instances of Eclipse so I could refer to some code in another workspace. Eventually I realized the two instances might be interfering with each other so I closed one. After that, I'm no longer seeing the "Can't bind..." error.
The actual answer to the "why" question (which is surprisingly ignored by the existing answers top this old question) is that this enum
declaration is probably located in a header file that is intended to be cross-compilable as both C and C++ code (i.e. included into both C and C++ implementation fiules). The art of writing such header files relies on the author's ability to select language features that have the proper compatible meaning in both languages.
C# is strongly typed so you can't create variables dynamically. You could use an array but a better C# way would be to use a Dictionary as follows. More on C# dictionaries here.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace QuickTest
{
class Program
{
static void Main(string[] args)
{
Dictionary<string, int> names = new Dictionary<string,int>();
for (int i = 0; i < 10; i++)
{
names.Add(String.Format("name{0}", i.ToString()), i);
}
var xx1 = names["name1"];
var xx2 = names["name2"];
var xx3 = names["name3"];
}
}
}
NOTE1: All com.android.support

You can still use the Visual Basic function in C#. The only thing you have to do is just follow my instructions shown below:
Then import it in your class as shown below:
using Microsoft.VisualBasic;
Next use it wherever you want as shown below:
if (!Information.IsNumeric(softwareVersion))
{
throw new DataException(string.Format("[{0}] is an invalid App Version! Only numeric values are supported at this time.", softwareVersion));
}
Hope, this helps and good luck!

Instead of using the dumpin.exe it is possible to call the link.exe with several options:
Example: link /dump /all myfile.lib
For detailed options see output of link /dump
In case of Visual Studio C++ Express installation, the link.exe is located here:
{root}\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\
The best way is to open the "Visual Studio Command Prompt" and then enter the lines above.
<input type="text" inputmode="decimal">
it will give u text input using numeric key-pad
This will validate against special characters and leading and trailing spaces:
var strString = "Your String";
strString.match(/^[A-Za-z0-9][A-Za-z0-9 ]\*[A-Za-z0-9]\*$/)
I don't know about javax.media.j3d, so I might be mistaken, but you usually want to investigate whether there is a memory leak. Well, as others note, if it was 64MB and you are doing something with 3d, maybe it's obviously too small...
But if I were you, I'll set up a profiler or visualvm, and let your application run for extended time (days, weeks...). Then look at the heap allocation history, and make sure it's not a memory leak.
If you use a profiler, like JProfiler or the one that comes with NetBeans IDE etc., you can see what object is being accumulating, and then track down what's going on.. Well, almost always something is incorrectly not removed from a collection...

If you want to update data you should use UPDATE
command instead of INSERT
Typically sites that do this by loading content via ajax and listening to the readystatechanged
event to update the DOM with a loading GIF or the content.
How are you currently loading your content?
The code would be similar to this:
function load(url) {
// display loading image here...
document.getElementById('loadingImg').visible = true;
// request your data...
var req = new XMLHttpRequest();
req.open("POST", url, true);
req.onreadystatechange = function () {
if (req.readyState == 4 && req.status == 200) {
// content is loaded...hide the gif and display the content...
if (req.responseText) {
document.getElementById('content').innerHTML = req.responseText;
document.getElementById('loadingImg').visible = false;
}
}
};
request.send(vars);
}
There are plenty of 3rd party javascript libraries that may make your life easier, but the above is really all you need.
An interesting alternative is to use Controllers which are responsible to show the views (dialogs).
How this works is shown by the WPF Application Framework (WAF).
Using plyr
package:
library(plyr)
count(mydf$V1)
It will return you a frequency of each value.
One issue with your ContentLoader is that internally it operates sequentially. A better pattern is to parallelize the work and then sychronize at the end, so we get
public class PageViewModel : IHandle<SomeMessage>
{
...
public async void Handle(SomeMessage message)
{
ShowLoadingAnimation();
// makes UI very laggy, but still not dead
await this.contentLoader.LoadContentAsync();
HideLoadingAnimation();
}
}
public class ContentLoader
{
public async Task LoadContentAsync()
{
var tasks = new List<Task>();
tasks.Add(DoCpuBoundWorkAsync());
tasks.Add(DoIoBoundWorkAsync());
tasks.Add(DoCpuBoundWorkAsync());
tasks.Add(DoSomeOtherWorkAsync());
await Task.WhenAll(tasks).ConfigureAwait(false);
}
}
Obviously, this doesn't work if any of the tasks require data from other earlier tasks, but should give you better overall throughput for most scenarios.

Find the below code in xampp/phpmyadmin/config.inc.php
$cfg['Servers'][$i]['controluser'] = 'user_name/root';
$cfg['Servers'][$i]['controlpass'] = 'passwaord';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'user_name/root';
$cfg['Servers'][$i]['password'] = 'password';
Replace each statement above with the corresponding entry below:
$cfg['Servers'][$i]['controluser'] = 'root';
$cfg['Servers'][$i]['controlpass'] = 'xxxx';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = 'xxxx';
Doing this caused localhost/phpmyadmin in the browser and the MySQL command prompt to work properly.
Copy the installation files into your hard drive. Rename the installer file name to vs_professional.exe for professional edition. Enjoy.
Be careful while adding a property to the existing object using .(dot) method.
(.dot) method of adding a property to the object should only be used if you know the 'key' beforehand otherwise use the [bracket] method.
Example:
var data = {_x000D_
'Property1': 1_x000D_
};_x000D_
_x000D_
// Two methods of adding a new property [ key (Property4), value (4) ] to the_x000D_
// existing object (data)_x000D_
data['Property2'] = 2; // bracket method_x000D_
data.Property3 = 3; // dot method_x000D_
console.log(data); // { Property1: 1, Property2: 2, Property3: 3 }_x000D_
_x000D_
// But if 'key' of a property is unknown and will be found / calculated_x000D_
// dynamically then use only [bracket] method not a dot method _x000D_
var key;_x000D_
for(var i = 4; i < 6; ++i) {_x000D_
key = 'Property' + i; // Key - dynamically calculated_x000D_
data[key] = i; // CORRECT !!!!_x000D_
}_x000D_
console.log(data); _x000D_
// { Property1: 1, Property2: 2, Property3: 3, Property4: 4, Property5: 5 }_x000D_
_x000D_
for(var i = 6; i < 2000; ++i) {_x000D_
key = 'Property' + i; // Key - dynamically calculated_x000D_
data.key = i; // WRONG !!!!!_x000D_
}_x000D_
console.log(data); _x000D_
// { Property1: 1, Property2: 2, Property3: 3, _x000D_
// Property4: 4, Property5: 5, key: 1999 }
_x000D_
Note the problem in the end of console log - 'key: 1999' instead of Property6: 6, Property7: 7,.........,Property1999: 1999. So the best way of adding dynamically created property is the [bracket] method.
You can use the standard Python idiom, vars()
:
for attr, value in vars(k).items():
print(attr, '=', value)
I got the same error while trying to install mysql-python
.
This is how I fixed it.
sudo PATH=/usr/local/mysql/bin/:$PATH pip install mysql-python
The problem was that the installer could not find the mysql_config in the default path. Now it can ..and it worked..

I went into wp-config/ and deleted the object-cache.php and advanced-cache.php and it worked fine for me.
The easiest solution is to toggleClass()
both classes individually.
Let's say you have an icon:
<i id="target" class="fa fa-angle-down"></i>
To toggle between fa-angle-down
and fa-angle-up
do the following:
$('.sometrigger').click(function(){
$('#target').toggleClass('fa-angle-down');
$('#target').toggleClass('fa-angle-up');
});
Since we had fa-angle-down
at the beginning without fa-angle-up
each time you toggle both, one leaves for the other to appear.
Try this:
.countTable table tr td:first-child + td
You could also reiterate in order to style the others columns:
.countTable table tr td:first-child + td + td {...} /* third column */
.countTable table tr td:first-child + td + td + td {...} /* fourth column */
.countTable table tr td:first-child + td + td + td +td {...} /* fifth column */
Simply replace image/jpeg
with application/octet-stream
. The client would not recognise the URL as an inline-able resource, and prompt a download dialog.
A simple JavaScript solution would be:
//var img = reference to image
var url = img.src.replace(/^data:image\/[^;]+/, 'data:application/octet-stream');
window.open(url);
// Or perhaps: location.href = url;
// Or even setting the location of an <iframe> element,
Another method is to use a blob:
URI:
var img = document.images[0];
img.onclick = function() {
// atob to base64_decode the data-URI
var image_data = atob(img.src.split(',')[1]);
// Use typed arrays to convert the binary data to a Blob
var arraybuffer = new ArrayBuffer(image_data.length);
var view = new Uint8Array(arraybuffer);
for (var i=0; i<image_data.length; i++) {
view[i] = image_data.charCodeAt(i) & 0xff;
}
try {
// This is the recommended method:
var blob = new Blob([arraybuffer], {type: 'application/octet-stream'});
} catch (e) {
// The BlobBuilder API has been deprecated in favour of Blob, but older
// browsers don't know about the Blob constructor
// IE10 also supports BlobBuilder, but since the `Blob` constructor
// also works, there's no need to add `MSBlobBuilder`.
var bb = new (window.WebKitBlobBuilder || window.MozBlobBuilder);
bb.append(arraybuffer);
var blob = bb.getBlob('application/octet-stream'); // <-- Here's the Blob
}
// Use the URL object to create a temporary URL
var url = (window.webkitURL || window.URL).createObjectURL(blob);
location.href = url; // <-- Download!
};
In my case, I was already logged-in and I just executed git push
.
Write this line after your insert code
ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Insert is successfull')", true);
You don't need to wrap the iframe with an additional tag. Just make sure you increase the width and height of the iframe by the same amount you scale down the iframe.
e.g. to scale the iframe content to 80% :
#frame { /* Example size! */
height: 400px; /* original height */
width: 100%; /* original width */
}
#frame {
height: 500px; /* new height (400 * (1/0.8) ) */
width: 125%; /* new width (100 * (1/0.8) )*/
transform: scale(0.8);
transform-origin: 0 0;
}
Basically, to get the same size iframe you need to scale the dimensions.
You can use this query to do the above task:

I was using express server with nodemon on NodeJS. I got the following message and it seems an error:
$ node ./bin/www
Port 3000 is already in use
There is a general solution that if you terminate all node server connections, you can add this code in your package.json file:
"scripts": {
"start": "node ./bin/www",
"stop": "taskkill -f -im node.exe"
},
In addition, I've found several solutions windows command and bash on Win 10 x64.

I also face the same problem. do the simple steps
v-flex does not have a display flex! Inspect v-flex in your browser and you will find out it is just a simple block div.
So, you should override it with display: flex
in your HTML or CSS to make it work with justify-content.
What you can do is the following:
.max-lines {_x000D_
display: block;/* or inline-block */_x000D_
text-overflow: ellipsis;_x000D_
word-wrap: break-word;_x000D_
overflow: hidden;_x000D_
max-height: 3.6em;_x000D_
line-height: 1.8em;_x000D_
}
_x000D_
<p class="max-lines">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc vitae leo dapibus, accumsan lorem eleifend, pharetra quam. Quisque vestibulum commodo justo, eleifend mollis enim blandit eu. Aenean hendrerit nisl et elit maximus finibus. Suspendisse scelerisque consectetur nisl mollis scelerisque.</p>
_x000D_
where max-height:
= line-height:
× <number-of-lines>
in em
.
or you can use package doBy
library(doBy)
dd <- orderBy(~-z+b, data=dd)
You need to make the strings raw and use latex:
fig.gca().set_ylabel(r'$\lambda$')
As of matplotlib 2.0 the default font supports most western alphabets and can simple do
ax.set_xlabel('?')
with unicode.
LinkedHashMap
is precisely what you're looking for.
It is exactly like HashMap
, except that when you iterate over it, it presents the items in the insertion order.
All good answers, but there's one difference I haven't seen mentioned yet, and that's how browsers render them by default. The major web browsers will render a <p>
tag with margin above and below the paragraph. A <div>
tag will be rendered without any margin at all.
See this Link
HTML
<div id="products"></div>
JS
var someone = {
"name":"Mahmoude Elghandour",
"price":"174 SR",
"desc":"WE Will BE WITH YOU"
};
var name = $("<div/>",{"text":someone.name,"class":"name"
});
var price = $("<div/>",{"text":someone.price,"class":"price"});
var desc = $("<div />", {
"text": someone.desc,
"class": "desc"
});
$("#products").fadeIn(1500);
$("#products").append(name).append(price).append(desc);
I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"
in my .html
<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">
then in my component.ts
reSearch(newValue: string) {
//this.searchText would equal the new value
//handle my filtering with the new value
}
You can use mongo --eval 'printjson(db.getCollectionNames())'
to get the list of collections
and then do a mongoexport on all of them.
Here is an example in ruby
out = `mongo #{DB_HOST}/#{DB_NAME} --eval "printjson(db.getCollectionNames())"`
collections = out.scan(/\".+\"/).map { |s| s.gsub('"', '') }
collections.each do |collection|
system "mongoexport --db #{DB_NAME} --collection #{collection} --host '#{DB_HOST}' --out #{collection}_dump"
end
Try setting mapper.configure(DeserializationConfig.Feature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT, true)
or
mapper.enable(DeserializationFeature.ACCEPT_EMPTY_STRING_AS_NULL_OBJECT);
depending on your Jackson version.
Since the question is general enough that it might attract people looking for answers to very trivial cases: if you just want a child rather than a descendant, you can use Linq:
private void ItemsControlItem_Loaded(object sender, RoutedEventArgs e)
{
if (SomeCondition())
{
var children = (sender as Panel).Children;
var child = (from Control child in children
where child.Name == "NameTextBox"
select child).First();
child.Focus();
}
}
or of course the obvious for loop iterating over Children.
Change the order in which you are doing things just a bit. You seem to be dividing by 2 for no particular reason at all.
While your application does not guarantee an input string of semi colon delimited variables you could easily make it do so:
package com;
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
// Good practice to initialize before use
Scanner keyboard = new Scanner(System.in);
String input = "";
// it's also a good idea to prompt the user as to what is going on
keyboardScanner : for (;;) {
input = keyboard.next();
if (input.indexOf(",") >= 0) { // Realistically we would want to use a regex to ensure [0-9],...etc groupings
break keyboardScanner; // break out of the loop
} else {
keyboard = new Scanner(System.in);
continue keyboardScanner; // recreate the scanner in the event we have to start over, just some cleanup
}
}
String strarray[] = input.split(","); // move this up here
int intarray[] = new int[strarray.length];
int count = 0; // Declare variables when they are needed not at the top of methods as there is no reason to allocate memory before it is ready to be used
for (count = 0; count < intarray.length; count++) {
intarray[count] = Integer.parseInt(strarray[count]);
}
for (int s : intarray) {
System.out.println(s);
}
}
}
I know this is an old question but I came across it while trying to solve this same issue. I thought it'd be worth sharing this solution I hadn't found anywhere else.
Basically the solution is to use CSS to hide the <input>
element and style a <label>
around it to look like a button. Click the 'Run code snippet' button to see the results.
I had used a JavaScript solution before that worked fine too but it is nice to solve a 'presentation' issue with just CSS.
label.cameraButton {_x000D_
display: inline-block;_x000D_
margin: 1em 0;_x000D_
_x000D_
/* Styles to make it look like a button */_x000D_

label.cameraButton:active {_x000D_
border-color: #CCC #EEE #EEE #CCC;_x000D_

Follow up to accepted answer.
You need something other than CTRL-D to designate the end if using this in a script. Try this instead:
cat << EOF >> filename
This is text entered via the keyboard or via a script.
EOF
This will append text to the stated file (not including "EOF").
It utilizes a here document (or heredoc).
However if you need sudo to append to the stated file, you will run into trouble utilizing a heredoc due to I/O redirection if you're typing directly on the command line.
This variation will work when you are typing directly on the command line:
sudo sh -c 'cat << EOF >> filename
This is text entered via the keyboard.
EOF'
Or you can use tee
instead to avoid the command line sudo issue seen when using the heredoc with cat:
tee -a filename << EOF
This is text entered via the keyboard or via a script.
EOF
Try this:
CASE WHEN table3.col3 IS NULL THEN table2.col3 ELSE table3.col3 END as col4
The as col4
should go at the end of the CASE the statement. Also note that you're missing the END
too.
Another probably more simple option would be:
IIf([table3.col3] Is Null,[table2.col3],[table3.col3])
Just to clarify, MS Access does not support COALESCE. If it would that would be the best way to go.
Edit after radical question change:
To turn the query into SQL Server then you can use COALESCE (so it was technically answered before too):
SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID,
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
COALESCE(dbo.EU_Admin3.EUID, dbo.EU_Admin2.EUID)
FROM dbo.AdminID
BTW, your CASE statement was missing a ,
before the field. That's why it didn't work.
The provided examples, using csv
modules, are great! Besides, you can always simply write to a text file using formatted strings, like the following tentative example:
l = [[1, 2], [2, 3], [4, 5]]
out = open('out.csv', 'w')
for row in l:
for column in row:
out.write('%d;' % column)
out.write('\n')
out.close()
I used ;
as separator, because it works best with Excell (one of your requirements).
Hope it helps!
I'd iterate through the options, comparing the text to what I want to be selected, then set the selected attribute on that option. Once you find the correct one, terminate the iteration (unless you have a multiselect).
$('#dropdown').find('option').each( function() {
var $this = $(this);
if ($this.text() == 'B') {
$this.attr('selected','selected');
return false;
}
});
You can simply use the zoom property:
#myContainer{
zoom: 0.5;
-moz-transform: scale(0.5);
}
Where myContainer contains all the elements you're editing. This is supported in all major browsers.
if you use this way :
dir, err := filepath.Abs(filepath.Dir(os.Args[0]))
if err != nil {
log.Fatal(err)
}
fmt.Println(dir)
you will get the /tmp path when you are running program using some IDE like GoLang because the executable will save and run from /tmp
i think the best way for getting the currentWorking Directory or '.' is :
import(
"os"
"fmt"
"log"
)
func main() {
dir, err := os.Getwd()
if err != nil {
log.Fatal(err)
}
fmt.Println(dir)
}
the os.Getwd() function will return the current working directory. and its all without using of any external library :D

The bind()
method takes an object as an first argument and creates a new function. When the function is invoked the value of this
in the function body will be the object which was passed in as an argument in the bind()
function.
this
work in JS anywayThe value of this
in javascript is dependent always depends on what Object the function is called. The value of this always refers to the object left of the dot from where is the function is called. In case of the global scope this is window
(or global
in nodeJS
). Only call
, apply
and bind
can alter the this binding differently. Here is an example to show how the this keyword works:
let obj = {_x000D_
prop1: 1,_x000D_
func: function () { console.log(this); } _x000D_
}_x000D_
_x000D_
obj.func(); // obj left of the dot so this refers to obj_x000D_
_x000D_
const customFunc = obj.func; // we store the function in the customFunc obj_x000D_
_x000D_
customFunc(); // now the object left of the dot is window, _x000D_
// customFunc() is shorthand for window.customFunc()_x000D_
// Therefore window will be logged
_x000D_
Bind can help in overcoming difficulties with the this
keyword by having a fixed object where this
will refer to. For example:
var name = 'globalName';_x000D_
_x000D_
const obj = {_x000D_
name: 'myName',_x000D_
sayName: function () { console.log(this.name);}_x000D_
}_x000D_
_x000D_
const say = obj.sayName; // we are merely storing the function the value of this isn't magically transferred_x000D_
_x000D_
say(); // now because this function is executed in global scope this will refer to the global var_x000D_
_x000D_
const boundSay = obj.sayName.bind(obj); // now the value of this is bound to the obj object_x000D_
_x000D_
boundSay(); // Now this will refer to the name in the obj object: 'myName'
_x000D_
Once the function is bound to a particular this
value we can pass it around and even put it on properties on other objects. The value of this
will remain the same.
The correct way to handle this is to "break" the link with jQuery when you handle the link
HTML
<a href="#" id="theLink">My Link</a>
JS
$('#theLink').click(function(ev){
// do whatever you want here
ev.preventDefault();
ev.stopPropagation();
});
Those final two calls stop the browser interpreting the click.
I think you want to specify
-H "Content-Type:text/xml"
with a colon, not an equals.
You simply have to pipe an iconv command before the sed command. Ex with file.txt input :
iconv -f ISO-8859-1 -t UTF8-MAC file.txt | sed 's/something/àéèêçùû/g' | .....
-f option is the 'from' codeset and -t option is the 'to' codeset conversion.
Take care of case, web pages usually show lowercase like that < charset=iso-8859-1"/> and iconv uses uppercase. You have list of iconv supported codesets in you system with command iconv -l
UTF8-MAC is modern OS Mac codeset for conversion.
If you need that in js code. You can use injected method of angula-filter lib. Like this.
function controller($scope, $http, groupByFilter) {
var groupedData = groupByFilter(originalArray, 'groupPropName');
}

After eight years, I faced the same challenge when trying to use the Stylish browser extension to change something on a website (not mine). And this time I made it work by looking at the source code using "inspect element" and created the CSS code based on that.

This is the same piece of the HTML and the CSS I used to modify the style:
td span[style="background-color: #e2047a;color:White;margin:2px;border-radius:2px;padding-left: 2px; padding-right: 2px;text-align: center;width: 45px; display: block;overflow: hidden;text-overflow: ellipsis;"] {_x000D_

You can run the code above and you will see that it works (tested in Chrome).
This is simply what I wanted back in the days when I asked this question.
I was using some sort of community blog/Myspace similar stuff and the only thing you had when styling your profile was their CSS editor, and that's why I wanted to select it based on the style.
I found the answer here:
MY SOLUTION!!!!!!! I fixed this problem when I was trying to install business objects. When the installer failed to register .dll's I inputted the MSVCR71.dll into both system32 and sysWOW64 then clicked retry. Installation finished. I did try adding this in before and after install but, install still failed.
Another way of saying it is that the i
in your function is bound at the time of executing the function, not the time of creating the function.
When you create the closure, i
is a reference to the variable defined in the outside scope, not a copy of it as it was when you created the closure. It will be evaluated at the time of execution.
Most of the other answers provide ways to work around by creating another variable that won't change the value for you.
Just thought I'd add an explanation for clarity. For a solution, personally, I'd go with Harto's since it is the most self-explanatory way of doing it from the answers here. Any of the code posted will work, but I'd opt for a closure factory over having to write a pile of comments to explain why I'm declaring a new variable(Freddy and 1800's) or have weird embedded closure syntax(apphacker).
Note: The user agent strings from Facebook's internal browser do indicate the actual physical device. Even the cellphone carrier (eg. AT&T)

These won't be the case in Safari or Chrome from iOS - only within the browser inside the Facebook app.
(I'm getting iPhone9
too though - not quite sure what that is!)
Why does this happen? When you install a fresh copy of linux, gcc compiler comes pre-packed with it. It only contains the files and binaries which are used to run the linux(to save space and time, obviously).
How to solve this error? All you need is to update your packages through the package manager and reinstall the build-essential packages. The commands might be different on different kernels.
I have tried all of them didn't work though,
console.log(clientIp);
console.log(req.ip);
console.log(req.headers['x-forwarded-for']);
console.log(req.connection.remoteAddress);
console.log(req.socket.remoteAddress);
console.log(req.connection.socket.remoteAddress.split(",")[0]);
When running an Express app behind a proxy for me Nginx, you have to set the application variable trust proxy to true. Express offers a few other trust proxy values which you can review in their documentation, but below steps worked for me.
app.set('trust proxy', true);
location / { proxy_pass http://localhost:3001; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $remote_addr; # this line proxy_cache_bypass $http_upgrade; }
module.exports = function(req, res, next) { let enable = true; // true/false let blacklist = ['x.x.x.x']; let whitelist = ['x.x.x.x']; let clientIp = req.header('x-forwarded-for') || req.connection.remoteAddress; if (!clientIp) { return res.json('Error'); } if (enable && paths.some((path) => (path === req.originalUrl))) { let blacklist = blacklist || []; if (blacklist.some((ip) => clientIp.match(ip) !== null)) { return res.json({ status: 401, error: 'Your IP is black-listed !'}); } let whitelist = whitelist || []; if (whitelist.length === 0 || whitelist.some((ip) => clientIp.match(ip) !== null)) { next(); return; } else { return res.json({ status: 401, error: 'Your IP is not listed !'}); } } next(); };
You want something like:
<appSettings>
<add key="developmentModeUserId" xdt:Transform="Remove" xdt:Locator="Match(key)"/>
<add key="developmentMode" value="false" xdt:Transform="SetAttributes"
xdt:Locator="Match(key)"/>
</appSettings>

You can access it as
element.dataset.points
etc. So in this case: this.dataset.points
Maven lets you specify either goals or lifecycle phases on the command line (or both).
clean
and install
are two different phases of two different lifecycles, to which different plugin goals are bound (either per default or explicitly in your pom.xml)
The clean
phase, per convention, is meant to make a build reproducible, i.e. it cleans up anything that was created by previous builds. In most cases it does that by calling clean:clean
, which deletes the directory bound to ${project.build.directory}
(usually called "target")
var q = from s in db.Serials
group s by s.Serial_Number into g
select new {Serial_Number = g.Key, MaxUid = g.Max(s => s.uid) }
I ran across a site a few weeks back. This is a working example of the first column locked but it is not browser compatible with Firefox. I didn't do a lot of checking around but it seems it only works in IE. There are some notes the author provided along with it that you can read.
Lock the First column: http://home.tampabay.rr.com/bmerkey/examples/locked-column-csv.html
Let me know if you need the Javascript to lock the Table headers too.
Vartec's answer with cURL didn't work for me. It did, with a slight improvement due to my specific problem.
e.g.,
When there is a redirect on the server (like when you are trying to save the facebook profile image) you will need following option set:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
The full solution becomes:
$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);
Dim sql As String = "
SELECT ID, Description
FROM inventory
ORDER BY DateAdded
"
You can combine them with string interpolation to maximize usefullness:
Dim primaryKey As String = "ID"
Dim inventoryTable As String = "inventory"
Dim sql As String = $"
SELECT {primaryKey}, Description
FROM {inventoryTable}
ORDER BY DateAdded
"
Note that interpolated strings begin with $
and you need to take care of "
, {
and }
contained inside – convert them into ""
, {{
or }}
respectively.
Here you can see actual syntax highlighting of interpolated parts of the above code example:
If you wonder if their recognition by the Visual Studio editor also works with refactoring (e.g. mass-renaming the variables), then you are right, code refactoring works with these. Not mentioning that they also support IntelliSense, reference counting or code analysis.
Animating items in the recyclerview when they are binded in the adapter might not be the best idea as that can cause the items in the recyclerview to animate at different speeds. In my case, the item at the end of the recyclerview animate to their position quicker then the ones at the top as the ones at the top have further to travel so it made it look untidy.
The original code that I used to animate each item into the recyclerview can be found here:
http://frogermcs.github.io/Instagram-with-Material-Design-concept-is-getting-real/
But I will copy and paste the code in case the link breaks.
STEP 1: Set this inside your onCreate method so that you ensure the animation only run once:
if (savedInstanceState == null) {
pendingIntroAnimation = true;
}
STEP 2: You will need to put this code into the method where you want to start the animation:
if (pendingIntroAnimation) {
pendingIntroAnimation = false;
startIntroAnimation();
}
In the link, the writer is animating the toolbar icons, so he put it inside this method:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
inboxMenuItem = menu.findItem(R.id.action_inbox);
inboxMenuItem.setActionView(R.layout.menu_item_view);
if (pendingIntroAnimation) {
pendingIntroAnimation = false;
startIntroAnimation();
}
return true;
}
STEP 3: Now write the logic for the startIntroAnimation():
private static final int ANIM_DURATION_TOOLBAR = 300;
private void startIntroAnimation() {
btnCreate.setTranslationY(2 * getResources().getDimensionPixelOffset(R.dimen.btn_fab_size));
int actionbarSize = Utils.dpToPx(56);
toolbar.setTranslationY(-actionbarSize);
ivLogo.setTranslationY(-actionbarSize);
inboxMenuItem.getActionView().setTranslationY(-actionbarSize);
toolbar.animate()
.translationY(0)
.setDuration(ANIM_DURATION_TOOLBAR)
.setStartDelay(300);
ivLogo.animate()
.translationY(0)
.setDuration(ANIM_DURATION_TOOLBAR)
.setStartDelay(400);
inboxMenuItem.getActionView().animate()
.translationY(0)
.setDuration(ANIM_DURATION_TOOLBAR)
.setStartDelay(500)
.setListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
startContentAnimation();
}
})
.start();
}
My preferred alternative:
I would rather animate the whole recyclerview instead of the items inside the recyclerview.
STEP 1 and 2 remains the same.
In STEP 3, as soon as your API call returns with your data, I would start the animation.
private void startIntroAnimation() {
recyclerview.setTranslationY(latestPostRecyclerview.getHeight());
recyclerview.setAlpha(0f);
recyclerview.animate()
.translationY(0)
.setDuration(400)
.alpha(1f)
.setInterpolator(new AccelerateDecelerateInterpolator())
.start();
}
This would animate your entire recyclerview so that it flys in from the bottom of the screen.
If g++
still gives error Try using:
g++ file.c -lstdc++
Look at this post: What is __gxx_personality_v0 for?
Make sure -lstdc++
is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.
def removeNonAscii(s): return "".join(filter(lambda x: ord(x)<128, s))
edit: my first impulse is always to use a filter, but the generator expression is more memory efficient (and shorter)...
def removeNonAscii(s): return "".join(i for i in s if ord(i)<128)
Keep in mind that this is guaranteed to work with UTF-8 encoding (because all bytes in multi-byte characters have the highest bit set to 1).
