This worked for me :
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.format.annotation.DateTimeFormat.ISO;
@Column(name="end_date", nullable = false)
@DateTimeFormat(iso = ISO.DATE_TIME)
@JsonFormat(pattern = "yyyy-MM-dd HH:mm")
private LocalDateTime endDate;
Expanding on retrography's answer..: I had this same problem even when using LocalDate
and not LocalDateTime
. The issue was that I had created my DateTimeFormatter
using .withResolverStyle(ResolverStyle.STRICT);
, so I had to use date pattern uuuuMMdd
instead of yyyyMMdd
(i.e. "year" instead of "year-of-era")!
DateTimeFormatter formatter = new DateTimeFormatterBuilder()
.parseStrict()
.appendPattern("uuuuMMdd")
.toFormatter()
.withResolverStyle(ResolverStyle.STRICT);
LocalDate dt = LocalDate.parse("20140218", formatter);
(This solution was originally a comment to retrography's answer, but I was encouraged to post it as a stand-alone answer because it apparently works really well for many people.)
The prefix "Local" in JSR-310 (aka java.time-package in Java-8) does not indicate that there is a timezone information in internal state of that class (here: LocalDateTime
). Despite the often misleading name such classes like LocalDateTime
or LocalTime
have NO timezone information or offset.
You tried to format such a temporal type (which does not contain any offset) with offset information (indicated by pattern symbol Z). So the formatter tries to access an unavailable information and has to throw the exception you observed.
Solution:
Use a type which has such an offset or timezone information. In JSR-310 this is either OffsetDateTime
(which contains an offset but not a timezone including DST-rules) or ZonedDateTime
. You can watch out all supported fields of such a type by look-up on the method isSupported(TemporalField).. The field OffsetSeconds
is supported in OffsetDateTime
and ZonedDateTime
, but not in LocalDateTime
.
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd HH:mm:ss.SSSSSS Z");
String s = ZonedDateTime.now().format(formatter);
If you're looking for short answer:
In the case of using java.util.Date, Java doesn't really know how to directly relate to SQL types. This is when @Temporal
comes into play. It's used to specify the desired SQL type.

Instants are already in UTC and already have a default date format of yyyy-MM-dd. If you're happy with that and don't want to mess with time zones or formatting, you could also toString()
it:
Instant instant = Instant.now();
instant.toString()
output: 2020-02-06T18:01:55.648475Z
Don't want the T and Z? (Z indicates this date is UTC. Z stands for "Zulu" aka "Zero hour offset" aka UTC):
instant.toString().replaceAll("[TZ]", " ")
output: 2020-02-06 18:01:55.663763
Want milliseconds instead of nanoseconds? (So you can plop it into a sql query):
instant.truncatedTo(ChronoUnit.MILLIS).toString().replaceAll("[TZ]", " ")
output: 2020-02-06 18:01:55.664
etc.
Use count(d.ertek)
or count(d.id)
instead of count(d)
. This can be happen when you have composite primary key at your entity.
Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity
).
Make sure you refer to the property as fileName
in the Criteria query, not filename
.
Specifically, Hibernate will call the getter method of the filename
property when executing that Criteria query, so it will look for a method called getFilename()
. But the property is called FileName
and the getter getFileName()
.
So, change the projection like so:
criteria.setProjection(Projections.property("fileName"));
Make sure that the attribute is primary key and Auto Incrementable in the database. Then map it into the data class with the annotation with @GeneratedValue
annotation using IDENTITY.
@Entity
@Table(name = "client")
data class Client(
@Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id") private val id: Int? = null
)
GL
use this, is work for me:
@Column(name = "candidate_id", nullable=false)
private Long candidate_id;
@ManyToOne(optional=false)
@JoinColumn(name = "candidate_id", insertable=false, updatable=false)
private Candidate candidate;
A simple alternative to using a custom UserType is to construct a new java.util.Date in the setter for the date property in your persisted bean, eg:
import java.util.Date;
import javax.persistence.Entity;
import javax.persistence.Column;
@Entity
public class Purchase {
private Date date;
@Column
public Date getDate() {
return this.date;
}
public void setDate(Date date) {
// force java.sql.Timestamp to be set as a java.util.Date
this.date = new Date(date.getTime());
}
}
Yes there is possible to close TCP or UDP port there is a command in DOS
TASKKILL /f /pid 1234
I hope this will work for You
Here's a quick overview:
One last thing: If you declare Foo foo;
without assigning it you don't have to worry - nothing is leaked. If Foo is a reference type, nothing was created. If Foo is a value type, it is allocated on the stack and thus will automatically be cleaned up.
Try this query (replace t.eventsDate
with e.eventsDate
):
SELECT e FROM Events e WHERE e.eventsDate BETWEEN :startDate AND :endDate
VERY IMPORTANT: If you are using LOMBOK, make shure to exclude attributes of collections like Set, List, etc...
Like this:
@EqualsAndHashCode(exclude = {"attributeOfTypeList", "attributeOfTypeSet"})
I have this working well using JPA2.0 and MySQL 5.5.10, for cases where I only care about the last time the row was modified. MySQL will create a timestamp on first insertion, and every time UPDATE is called on the row. (NOTE: this will be problematic if I cared whether or not the UPDATE actually made a change).
The "timestamp" column in this example is like a "last-touched" column.x`
The code below uses a separate column "version" for optimistic locking.
private long version;
private Date timeStamp
@Version
public long getVersion() {
return version;
}
public void setVersion(long version) {
this.version = version;
}
// columnDefinition could simply be = "TIMESTAMP", as the other settings are the MySQL default
@Column(name="timeStamp", columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP")
@Temporal(TemporalType.TIMESTAMP)
public Date getTimeStamp() {
return timeStamp;
}
public void setTimeStamp(Date timeStamp) {
this.timeStamp = timeStamp;
}
(NOTE: @Version doesn't work on a MySQL "DATETIME" column, where the attribute type is "Date" in the Entity class. This was because Date was generating a value down to the millisecond, however MySQL was not storing the millisecond, so when it did a comparison between what was in the database, and the "attached" entity, it thought they had different version numbers)
From the MySQL manual regarding TIMESTAMP :
With neither DEFAULT nor ON UPDATE clauses, it is the same as DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP.
To allow cross domain:
about:config
security.fileuri.strict_origin_policy
in the search barYou can now close the tab. Normally you can now make cross domain request with this config.
See here for more details.
In your case (creating a list) there is no difference in practice. But generally it is better to use setUp(), because that will help Junit to report Exceptions correctly. If an exception occurs in constructor/initializer of a Test, that is a test failure. However, if an exception occurs during setup, it is natural to think of it as some issue in setting up the test, and junit reports it appropriately.
To the best of my knowledge, you need to put your entire Java app in UTC timezone (so that Hibernate will store dates in UTC), and you'll need to convert to whatever timezone desired when you display stuff (at least we do it this way).
At startup, we do:
TimeZone.setDefault(TimeZone.getTimeZone("Etc/UTC"));
And set the desired timezone to the DateFormat:
fmt.setTimeZone(TimeZone.getTimeZone("Europe/Budapest"))
Taking the resources in this post along with information taken left and right from different sources, I came with this elegant solution, create the following abstract class
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.MappedSuperclass;
import javax.persistence.PrePersist;
import javax.persistence.PreUpdate;
import javax.persistence.Temporal;
import javax.persistence.TemporalType;
@MappedSuperclass
public abstract class AbstractTimestampEntity {
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "created", nullable = false)
private Date created;
@Temporal(TemporalType.TIMESTAMP)
@Column(name = "updated", nullable = false)
private Date updated;
@PrePersist
protected void onCreate() {
updated = created = new Date();
}
@PreUpdate
protected void onUpdate() {
updated = new Date();
}
}
and have all your entities extend it, for instance:
@Entity
@Table(name = "campaign")
public class Campaign extends AbstractTimestampEntity implements Serializable {
...
}
If you are issuing a single command with several select statements, you might use NextResult method to move to next resultset within the datareader: http://msdn.microsoft.com/en-us/library/system.data.idatareader.nextresult.aspx
I show how it could look bellow:
public DataSet SelectOne(int id)
{
DataSet result = new DataSet();
using (DbCommand command = Connection.CreateCommand())
{
command.CommandText = @"
select * from table1
select * from table2
";
var param = ParametersBuilder.CreateByKey(command, "ID", id, null);
command.Parameters.Add(param);
Connection.Open();
using (DbDataReader reader = command.ExecuteReader())
{
result.MainTable.Load(reader);
reader.NextResult();
result.SecondTable.Load(reader);
// ...
}
Connection.Close();
}
return result;
}
I think you could do:
$('#google_translate_element').find('*').each(function(){
$(this).unbind('click');
});
but it would cause a lot of overhead
It works for me. The Java code works exactly as you wrote it. In the tester, the input string should be:
This is a string.
This is a long string.
...with a real linefeed. You can't use:
This is a string.\nThis is a long string.
...because it treats \n
as the literal sequence backslash 'n'.

I had to use the following steps to get there.
1) Ensure that pip and django are installed at the sudo level
2) Ensure that security group in-bound rules includ http on port 80 for 0.0.0.0/0
3) Add Public IP and DNS to ALLOWED_HOSTS
4) Launch development server with sudo on port 80

A monad is a data type that encapsulates a value, and to which, essentially, two operations can be applied:
return x
creates a value of the monad type that encapsulates x
m >>= f
(read it as "the bind operator") applies the function f
to the value in the monad m
That's what a monad is. There are a few more technicalities, but basically those two operations define a monad. The real question is, "What a monad does?", and that depends on the monad — lists are monads, Maybes are monads, IO operations are monads. All that it means when we say those things are monads is that they have the monad interface of return
and >>=
.
Your quotes are in the wrong spot. Here's a simple example:
<div style={{backgroundColor: "#FF0000"}}>red</div>
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import os
from flask import Flask, redirect, url_for
app = Flask(__name__)
@app.route('/')
def hello():
return redirect(url_for('foo'))
@app.route('/foo')
def foo():
return 'Hello Foo!'
if __name__ == '__main__':
# Bind to PORT if defined, otherwise default to 5000.
port = int(os.environ.get('PORT', 5000))
app.run(host='0.0.0.0', port=port)
Take a look at the example in the documentation.
There is no command to do exactly what you asked.
Here are some close matches.
You can delete all the pods in a single namespace with this command:
kubectl delete --all pods --namespace=foo
You can also delete all deployments in namespace which will delete all pods attached with the deployments corresponding to the namespace
kubectl delete --all deployments --namespace=foo
You can delete all namespaces and every object in every namespace (but not un-namespaced objects, like nodes and some events) with this command:
kubectl delete --all namespaces
However, the latter command is probably not something you want to do, since it will delete things in the kube-system namespace, which will make your cluster not usable.
This command will delete all the namespaces except kube-system, which might be useful:
for each in $(kubectl get ns -o jsonpath="{.items[*].metadata.name}" | grep -v kube-system);
do
kubectl delete ns $each
done
You could also grab the attributes with the getAttribute() method which will return the value of a specific HTML attribute.
var elem = document.getElementById('the-span');_x000D_
_x000D_
var typeId = elem.getAttribute('data-typeId');_x000D_
var type = elem.getAttribute('data-type');_x000D_
var points = elem.getAttribute('data-points');_x000D_
var important = elem.getAttribute('data-important');_x000D_
_x000D_
console.log(`typeId: ${typeId} | type: ${type} | points: ${points} | important: ${important}`_x000D_
);
_x000D_
<span data-typeId="123" data-type="topic" data-points="-1" data-important="true" id="the-span"></span>

element.try changing OUT
to INOUT
for your out_number
parameter definition.
CREATE PROCEDURE my_sqrt(input_number INT, INOUT out_number FLOAT)
INOUT
means that the input variable for out_number
(@out_value
in your case.) will also serve as the output variable from which you can select the value from.
Here is a simple example, using class:
$input = array(
'element1' => 'value1',
'element2' => 'value2',
'element3' => 'value3'
);
echo FlatData::flatArray($input,', ', '=');
class FlatData
{
public static function flatArray(array $input = array(), $separator_elements = ', ', $separator = ': ')
{
$output = implode($separator_elements, array_map(
function ($v, $k, $s) {
return sprintf("%s{$s}%s", $k, $v);
},
$input,
array_keys($input),
array_fill(0, count($input), $separator)
));
return $output;
}
}
You should try and avoid jQuery in ReactJS. But if you really want to use it, you'd put it in componentDidMount() lifecycle function of the component.
e.g.
class App extends React.Component {
componentDidMount() {
// Jquery here $(...)...
}
// ...
}
Ideally, you'd want to create a reusable Accordion component. For this you could use Jquery, or just use plain javascript + CSS.
class Accordion extends React.Component {
constructor() {
super();
this._handleClick = this._handleClick.bind(this);
}
componentDidMount() {
this._handleClick();
}
_handleClick() {
const acc = this._acc.children;
for (let i = 0; i < acc.length; i++) {
let a = acc[i];
a.onclick = () => a.classList.toggle("active");
}
}
render() {
return (
<div
ref={a => this._acc = a}
onClick={this._handleClick}>
{this.props.children}
</div>
)
}
}
Then you can use it in any component like so:
class App extends React.Component {
render() {
return (
<div>
<Accordion>
<div className="accor">
<div className="head">Head 1</div>
<div className="body"></div>
</div>
</Accordion>
</div>
);
}
}

You have to load the db library first. In autoload.php
add :
$autoload['libraries'] = array('database');
Also, try renaming User model class for "User_model".
var array = [];
//length array now = 0
array[array.length] = 'hello';
//length array now = 1
// 0
//array = ['hello'];//length = 1
pad
In order to move the colorbar relative to the subplot, one may use the pad
argument to fig.colorbar
.
import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)
fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")
fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()
One can use an instance of make_axes_locatable
to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad
argument would allow to set the space between the two axes.
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)
fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")
divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")
plt.show()
One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios
as gridspec_kw={"height_ratios":[1, 0.05]}
in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.
import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)
fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4),
gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")
fig.colorbar(im, cax=cax, orientation="horizontal")
plt.show()
Simply have a look a look at https://www.w3.org/.
The image has a z-index:1
, the text is here but behind because of the z-index:0
coupled to the position: absolute;

<img src="/2008/site/images/logo-w3c-mobile-lg" width="90" height="53" alt="W3C">
</a>
<span class="alt-logo">W3C</span>
</h1>
The original CSS:
#w3c_mast h1 a {
display: block;
float: left;
background: url(../images/logo-w3c-screen-lg) no-repeat top left;
width: 100%;
height: 107px;
position: relative;

}

Delete the project from your workspace & import again.
This worked for me.
Can't believe similar issue has been there since 2008.

There are several related solutions available on the internet, but it all depends on the configuration of the machine and the firewall rules.
For me below solution is worked:
I catch the next case about cors. Maybe it will be useful to somebody. If you add feature 'WebDav Redirector' to your server, PUT and DELETE requests are failed.
So, you will need to remove 'WebDAVModule' from your IIS server:
Or add to your config:
<system.webServer>
<modules>
<remove name="WebDAVModule"/>
</modules>
<handlers>
<remove name="WebDAV" />
...
</handlers>
Using Node.js
sync mode:
var fs = require("fs");
var text = fs.readFileSync("./mytext.txt");
var textByLine = text.split("\n")
async mode:
var fs = require("fs");
fs.readFile("./mytext.txt", function(text){
var textByLine = text.split("\n")
});
UPDATE
As of at least Node 6, readFileSync
returns a Buffer
, so it must first be converted to a string in order for split
to work:
var text = fs.readFileSync("./mytext.txt").toString('utf-8');
Or
var text = fs.readFileSync("./mytext.txt", "utf-8");

In order to send data from child component create property decorated with output() in child component and in the parent listen to the created event. Emit this event with new values in the payload when ever it needed.
@Output() public eventName:EventEmitter = new EventEmitter();
to emit this event:

You want an independent for loop for all the rows in grid view, then refer the below link
http://nikhilsreeni.wordpress.com/asp-net/checkbox/
Select all checkbox in Gridview
CheckBox cb = default(CheckBox);

{
cb = (CheckBox)grdforumcomments.Rows[i].Cells[0].FindControl(“cbSel”);
cb.Checked = ((CheckBox)sender).Checked;
}
Select checked rows to a dataset; For gridview multiple edit
CheckBox cb = default(CheckBox);
foreach (GridViewRow row in grdforumcomments.Rows)
{
cb = (CheckBox)row.FindControl("cbsel");
if (cb.Checked)
{
drArticleCommentsUpdates = dtArticleCommentsUpdates.NewRow();
drArticleCommentsUpdates["Id"] = dgItem.Cells[0].Text;

Sorry, not enough rep to add a comment, but from zmbq's answer:
Anyway, to see if a cookie exists, you can check Cookies.Get(string), this will not modify the cookie collection.
is maybe not fully correct, as Cookies.Get(string) will actually create a cookie with that name, if it does not already exist. However, as he said, you need to be looking at Request.Cookies, not Response.Cookies So, something like:
bool cookieExists = HttpContext.Current.Request.Cookies["cookie_name"] != null;
Similar kind of thing I tried with normal javascript
function fixedEncodeURIComponent(str){
return encodeURIComponent(str).replace(/[!'()]/g, escape).replace(/\*/g, "%2A");

You might want to take a look at Standard Compression Scheme for Unicode.
SQL Server 2008 R2 use it internally and can achieve up to 50% compression.

To conditionally check the length of the string, use CASE
.
SELECT CASE WHEN LEN(comments) <= 60
THEN comments
ELSE LEFT(comments, 60) + '...'
END As Comments

WHERE joiningdate >= NOW();
Another solution to handle this case is creating a customized Seekbar, to get ride of converting the real value and SeekBar progress every time:
import android.content.Context
import android.util.AttributeSet
import android.widget.SeekBar
//
// Require SeekBar with range [Min, Max] and INCREMENT value,
// However, Android Seekbar starts from 0 and increment is 1 by default, Android supports min attr on API 26,
// To make a increment & range Seekbar, we can do the following conversion:
//
// seekbar.setMax((Max - Min) / Increment)
// seekbar.setProgress((actualValue - Min) / Increment)
// seekbar.getProgress = Min + (progress * Increment)
//
// The RangeSeekBar is responsible for handling all these logic inside the class.
data class Range(val min: Int, val max: Int, private val defaultIncrement: Int) {
val increment = if ((max - min) < defaultIncrement) 1 else defaultIncrement
}
internal fun Range.toSeekbarMaximum(): Int = (max - min) / increment
class RangeSeekBar: SeekBar, SeekBar.OnSeekBarChangeListener {
constructor(context: Context) : super(context)
constructor(context: Context, attrs: AttributeSet) : super(context, attrs)
var range: Range = Range(0, 100, 1)
set(value) {
field = value
max = value.toSeekbarMaximum()
}
var value: Int = 0
get() = range.min + progress * range.increment
set(value) {
progress = (value - range.min) / range.increment
field = value
}
var onSeekBarChangeListenerDelegate: OnSeekBarChangeListener? = this
override fun setOnSeekBarChangeListener(l: OnSeekBarChangeListener?) {
onSeekBarChangeListenerDelegate = l
super.setOnSeekBarChangeListener(this)
}
override fun onProgressChanged(seekBar: SeekBar?, progress: Int, fromUser: Boolean) {
onSeekBarChangeListenerDelegate?.onProgressChanged(seekBar, value, fromUser)
}
override fun onStartTrackingTouch(seekBar: SeekBar?) {
onSeekBarChangeListenerDelegate?.onStartTrackingTouch(seekBar)
}
override fun onStopTrackingTouch(seekBar: SeekBar?) {
onSeekBarChangeListenerDelegate?.onStopTrackingTouch(seekBar)
}
}
Then in your fragment,
// init
range_seekbar.range = Range(10, 110, 10)
range_seekbar.value = 20
// observe value changes
range_seekbar.userChanges().skipInitialValue().subscribe {
println("current value=$it")
}

While the top answer here is a workaround for the asker's particular case, if you're looking for a solution to actually using 'starts with' on individual class names:
You can use this custom jQuery selector, which I call :acp()
for "A Class Prefix." Code is at the bottom of this post.
var test = $('div:acp("starting_text")');
This will select any and all <div>
elements that have at least one class name beginning with the given string ("starting_text" in this example), regardless of whether that class is at the beginning or elsewhere in the class attribute strings.
<div id="1" class="apple orange lemon" />
<div id="2" class="orange applelemon banana" />
<div id="3" class="orange lemon apple" />
<div id="4" class="lemon orangeapple" />
<div id="5" class="lemon orange" />
var startsWithapp = $('div:acp("app")');
This will return elements 1, 2, and 3, but not 4 or 5.
Here's the declaration for the :acp
custom selector, which you can put anywhere:
$(function(){
$.expr[":"].acp = function(elem, index, m){
var regString = '\\b' + m[3];
var reg = new RegExp(regString, "g");
return elem.className.match(reg);
}
});
I made this because I do a lot of GreaseMonkey hacking of websites on which I have no backend control, so I often need to find elements with class names that have dynamic suffixes. It's been very useful.
Only text type
$(".form-edit-account :input[type=text]").attr("disabled", "disabled");
Only Password type
$(".form-edit-account :input[type=password]").attr("disabled", "disabled");
Only Email Type
$(".form-edit-account :input[type=email]").attr("disabled", "disabled");

Then, supposing you name the script as co, say, do something like this to get the sizes of files (the example assumes you're using Linux, but the script itself is OS-independent) :-
ls -lh | co 5
Could it be that your file is not ISO-8859-15 encoded? You should be able to check with the file command:
file YourFile.txt
Also, you can use iconv without providing the encoding of the original file:
iconv -t UTF-8 YourFile.txt
Use the DOM's getElementByid
method:
document.getElementById("DATE").value = "your date";
A date can be made with the Date
class:
d = new Date();
(Protip: install a javascript console such as in Chrome or Firefox' Firebug extension. It enables you to play with the DOM and Javascript)
If they are two integers you can try a quick and dirty trick: Map<String, ?>
using the key as i+"#"+j
.
If the key i+"#"+j
is the same as j+"#"+i
try min(i,j)+"#"+max(i,j)
.
Maybe these two examples illustrate you the difference between a deadlock and a livelock:
Java-Example for a deadlock:
import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;
public class DeadlockSample {
private static final Lock lock1 = new ReentrantLock(true);
private static final Lock lock2 = new ReentrantLock(true);
public static void main(String[] args) {
Thread threadA = new Thread(DeadlockSample::doA,"Thread A");
Thread threadB = new Thread(DeadlockSample::doB,"Thread B");
threadA.start();
threadB.start();
}
public static void doA() {
System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
lock1.lock();
System.out.println(Thread.currentThread().getName() + " : holds lock 1");
try {
System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
lock2.lock();
System.out.println(Thread.currentThread().getName() + " : holds lock 2");
try {
System.out.println(Thread.currentThread().getName() + " : critical section of doA()");
} finally {
lock2.unlock();
System.out.println(Thread.currentThread().getName() + " : does not hold lock 2 any longer");
}
} finally {
lock1.unlock();
System.out.println(Thread.currentThread().getName() + " : does not hold lock 1 any longer");
}
}
public static void doB() {
System.out.println(Thread.currentThread().getName() + " : waits for lock 2");
lock2.lock();
System.out.println(Thread.currentThread().getName() + " : holds lock 2");
try {
System.out.println(Thread.currentThread().getName() + " : waits for lock 1");
lock1.lock();
System.out.println(Thread.currentThread().getName() + " : holds lock 1");
try {

}
} finally {
lock2.unlock();
System.out.println(Thread.currentThread().getName() + " : does not hold lock 2 any longer");
}
}
}
Sample output:

Thread B : waits for lock 2
Thread A : holds lock 1
Thread B : holds lock 2
Thread B : waits for lock 1

Both examples force the threads to aquire the locks in different orders. While the deadlock waits for the other lock, the livelock does not really wait - it desperately tries to acquire the lock without the chance of getting it. Every try consumes CPU cycles.
https://github.com/stephenlb/geo-ip will generate a list of Valid IP Public Addresses including Localities.
'1.0.0.0/8'
to '191.0.0.0/8'
are the valid public IP Address range exclusive of the reserved Private IP Addresses as follows:
import iptools
## Private IP Addresses
private_ips = iptools.IpRangeList(
'0.0.0.0/8', '10.0.0.0/8', '100.64.0.0/10', '127.0.0.0/8',
'169.254.0.0/16', '172.16.0.0/12', '192.0.0.0/24', '192.0.2.0/24',
'192.88.99.0/24', '192.168.0.0/16', '198.18.0.0/15', '198.51.100.0/24',
'203.0.113.0/24', '224.0.0.0/4', '240.0.0.0/4', '255.255.255.255/32'
)
Generates a JSON dump of IP Addresses and associated Geo information.
Note that the valid public IP Address range is
from '1.0.0.0/8'
to '191.0.0.0/8'
excluding the reserved
Private IP Address ranges shown lower down in this readme.
docker build -t geo-ip .
docker run -e IPRANGE='54.0.0.0/30' geo-ip ## a few IPs
docker run -e IPRANGE='54.0.0.0/26' geo-ip ## a few more IPs
docker run -e IPRANGE='54.0.0.0/16' geo-ip ## a lot more IPs
docker run -e IPRANGE='0.0.0.0/0' geo-ip ## ALL IPs ( slooooowwwwww )
docker run -e IPRANGE='0.0.0.0/0' geo-ip > geo-ip.json ## ALL IPs saved to JSON File
docker run geo-ip
A little faster option for scanning all valid public addresses:
for i in $(seq 1 191); do \
docker run -e IPRANGE="$i.0.0.0/8" geo-ip; \
sleep 1; \
done
This prints less than 4,228,250,625 JSON lines to STDOUT. Here is an example of one of the lines:
{"city": "Palo Alto", "ip": "0.0.0.0", "longitude": -122.1274,
"continent": "North America", "continent_code": "NA",
"state": "California", "country": "United States", "latitude": 37.418,
"iso_code": "US", "state_code": "CA", "aso": "PubNub",
"asn": "11404", "zip_code": "94107"}
The dockerfile in the repo above will exclude non-usable IP addresses following the guide from the wikipedia article: https://en.wikipedia.org/wiki/Reserved_IP_addresses
The dockerfile imports a free public Database provided by https://www.maxmind.com/en/home

You cannot insert a class into a vector, you can insert an object (provided that it is of the proper type or convertible) of a class though.
If the type Player
has a default constructor, you can create a temporary object by doing Player()
, and that should work for your case:
vectorOfGamers.push_back(Player());
Assert.Throws
returns the exception that's thrown which lets you assert on the exception.
var ex = Assert.Throws<Exception>(() => user.MakeUserActive());
Assert.That(ex.Message, Is.EqualTo("Actual exception message"));
So if no exception is thrown, or an exception of the wrong type is thrown, the first Assert.Throws
assertion will fail. However if an exception of the correct type is thrown then you can now assert on the actual exception that you've saved in the variable.
By using this pattern you can assert on other things than the exception message, e.g. in the case of ArgumentException
and derivatives, you can assert that the parameter name is correct:
var ex = Assert.Throws<ArgumentNullException>(() => foo.Bar(null));
Assert.That(ex.ParamName, Is.EqualTo("bar"));
You can also use the fluent API for doing these asserts:
Assert.That(() => foo.Bar(null),
Throws.Exception
.TypeOf<ArgumentNullException>()
.With.Property("ParamName")
.EqualTo("bar"));
or alternatively
Assert.That(
Assert.Throws<ArgumentNullException>(() =>
foo.Bar(null)
.ParamName,
Is.EqualTo("bar"));
A little tip when asserting on exception messages is to decorate the test method with the SetCultureAttribute
to make sure that the thrown message is using the expected culture. This comes into play if you store your exception messages as resources to allow for localization.
This destroyed me for a while.... I knew that there HAD to be an easier way with a world class IDE like Netbeans.
The easiest method is to press Shift+F11 (Clean and Build Project), then hit F6 to run it.
It refreshes Netbeans appropriately and finds your main without all the manual labor; and if you have multiple mains, it will give you the option to select the correct one.

You have to add android:exported="true"
in the manifest file in the activity you are trying to start.
From the android:exported documentation:
android:exported
Whether or not the activity can be launched by components of other applications — "true" if it can be, and "false" if not. If "false", the activity can be launched only by components of the same application or applications with the same user ID.The default value depends on whether the activity contains intent filters. The absence of any filters means that the activity can be invoked only by specifying its exact class name. This implies that the activity is intended only for application-internal use (since others would not know the class name). So in this case, the default value is "false". On the other hand, the presence of at least one filter implies that the activity is intended for external use, so the default value is "true".
This attribute is not the only way to limit an activity's exposure to other applications. You can also use a permission to limit the external entities that can invoke the activity (see the permission attribute).

This can be the message you receive even when custom errors is turned off in web.config file. It can mean you have run out of free space on the drive that hosts the application. Clean your log files if you have no other space to gain on the drive.
You are tying one had behind your back saying that you won't use the LESS files. I built my first Twitter Bootstrap theme using 2.0, and I did everything in CSS -- creating an override.css file. It took days to get things to work correctly.
Now we have 3.0. Let me assure you that it takes less time to learn LESS, which is pretty straight forward if you're comfortable with CSS, than doing all of those crazy CSS overrides. Making changes like the one you want is a piece of cake.
In Bootstrap 3.0, the container class controls the width, and all of the contained styles adjust to fill the container. The container width variables are at the bottom of the variables.less file.
// Container sizes
// --------------------------------------------------
// Small screen / tablet
@container-tablet: ((720px + @grid-gutter-width));
// Medium screen / desktop
@container-desktop: ((940px + @grid-gutter-width));
// Large screen / wide desktop
@container-lg-desktop: ((1020px + @grid-gutter-width));
Some sites either don't have enough content to fill the 1020 display or you want a narrower frame for aesthetic reasons. Because BS uses a 12-column grid I use a multiple like 960.
This code is working fine for me,
var a = serializer.Deserialize<List<Entity>>(json);
To augment T.J.'s answer, exceeding the min/max values generates an Invalid Date.

console.log(new Date(maxDate.getTime() + 1).toString()); // Invalid Date_x000D_
_x000D_
console.log(new Date(minDate.getTime()).toString());_x000D_
console.log(new Date(minDate.getTime() + 1).toString());_x000D_
console.log(new Date(minDate.getTime() - 1).toString()); // Invalid Date

I quote from http://www.php.net/manual/en/language.oop5.visibility.php
Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword). In PHP 5 before 5.1.3, its usage would generate an
E_STRICT
warning.
Try doing a nav
element with a ul
element. Mine has a main
above but I don't think you need it.
<main>
<nav>
<ul><li><a href="http//www.google.com">search</a>
<li><a href="http//www.google.com">search</a>
<li><a href="http//www.google.com">search</a>
The code is something like this.
When ever I put in the code it wouldn't work right so you need to fill in the blank,
then center it.
main
nav
ul> li> a>: href="link of choice":name of link:/a>
RecyclerView doesn't provide straightforward interface for drawing dividers of lists. But actually it provides us a much more flexible way to draw dividers. We use RecyclerView.ItemDecoration to decorate RecyclerView's tiles with dividers or anything you want. That is also why it is called ItemDecoration.
As described in Meterial Design Guidelines:
The divider sits within the baseline of the tile.
So if you want to follow the Material Design Guidelines, you don't need extra space to draw the dividers. Just draw them on the tiles. However, you have the right to do whatever you want to do. So I implemented one which gives you the ability to set insets as well as draw on/underneath the tiles.
public class InsetDivider extends RecyclerView.ItemDecoration {
public static final int HORIZONTAL_LIST = LinearLayoutManager.HORIZONTAL;
public static final int VERTICAL_LIST = LinearLayoutManager.VERTICAL;
private Paint mPaint;
// in pixel
private int mDividerHeight;
// left inset for vertical list, top inset for horizontal list
private int mFirstInset;
// right inset for vertical list, bottom inset for horizontal list
private int mSecondInset;
private int mColor;
private int mOrientation;
// set it to true to draw divider on the tile, or false to draw beside the tile.
// if you set it to false and have inset at the same time, you may see the background of
// the parent of RecyclerView.
private boolean mOverlay;
private InsetDivider() {
mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
mPaint.setStyle(Paint.Style.FILL);
}
public int getDividerHeight() {
return mDividerHeight;
}
public void setDividerHeight(int dividerHeight) {
this.mDividerHeight = dividerHeight;
}
public int getFirstInset() {
return mFirstInset;
}
public void setFirstInset(int firstInset) {
this.mFirstInset = firstInset;
}
public int getSecondInset() {
return mSecondInset;
}
public void setSecondInset(int secondInset) {
this.mSecondInset = secondInset;
}
public int getColor() {
return mColor;
}
public void setColor(int color) {
this.mColor = color;
mPaint.setColor(color);
}
public int getOrientation() {
return mOrientation;
}
public void setOrientation(int orientation) {
this.mOrientation = orientation;
}
public boolean getOverlay() {
return mOverlay;
}
public void setOverlay(boolean overlay) {
this.mOverlay = overlay;
}
@Override
public void onDrawOver(Canvas c, RecyclerView parent, RecyclerView.State state) {
if (mOrientation == VERTICAL_LIST) {
drawVertical(c, parent);
} else {
drawHorizontal(c, parent);
}
}
protected void drawVertical(Canvas c, RecyclerView parent) {
final int left = parent.getPaddingLeft() + mFirstInset;
final int right = parent.getWidth() - parent.getPaddingRight() - mSecondInset;
final int childCount = parent.getChildCount();
for (int i = 0; i < childCount; i++) {
final View child = parent.getChildAt(i);
if (parent.getChildAdapterPosition(child) == (parent.getAdapter().getItemCount() - 1)) {
continue;
}
final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();
final int bottom;
final int top;
if (mOverlay) {
bottom = child.getBottom() + params.bottomMargin + Math.round(ViewCompat.getTranslationY(child));
top = bottom - mDividerHeight;
} else {
top = child.getBottom() + params.bottomMargin + Math.round(ViewCompat.getTranslationY(child));
bottom = top + mDividerHeight;
}
c.drawRect(left, top, right, bottom, mPaint);
}
}
protected void drawHorizontal(Canvas c, RecyclerView parent) {
final int top = parent.getPaddingTop() + mFirstInset;
final int bottom = parent.getHeight() - parent.getPaddingBottom() - mSecondInset;
final int childCount = parent.getChildCount();
for (int i = 0; i < childCount; i++) {
final View child = parent.getChildAt(i);
if (parent.getChildAdapterPosition(child) == (parent.getAdapter().getItemCount() - 1)) {
continue;
}
final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child
.getLayoutParams();
final int right;
final int left;
if (mOverlay) {
right = child.getRight() + params.rightMargin + Math.round(ViewCompat.getTranslationX(child));
left = right - mDividerHeight;
} else {
left = child.getRight() + params.rightMargin + Math.round(ViewCompat.getTranslationX(child));
right = left + mDividerHeight;
}
c.drawRect(left, top, right, bottom, mPaint);
}
}
@Override
public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
if (mOverlay) {
super.getItemOffsets(outRect, view, parent, state);
return;
}
if (mOrientation == VERTICAL_LIST) {
outRect.set(0, 0, 0, mDividerHeight);
} else {
outRect.set(0, 0, mDividerHeight, 0);
}
}
/**
* Handy builder for creating {@link InsetDivider} instance.
*/
public static class Builder {
private Context mContext;
private int mDividerHeight;
private int mFirstInset;
private int mSecondInset;
private int mColor;
private int mOrientation;
private boolean mOverlay = true; // set default to true to follow Material Design Guidelines
public Builder(Context context) {
mContext = context;
}
public Builder dividerHeight(int dividerHeight) {
mDividerHeight = dividerHeight;
return this;
}
public Builder insets(int firstInset, int secondInset) {
mFirstInset = firstInset;
mSecondInset = secondInset;
return this;
}
public Builder color(@ColorInt int color) {
mColor = color;
return this;
}
public Builder orientation(int orientation) {
mOrientation = orientation;
return this;
}
public Builder overlay(boolean overlay) {
mOverlay = overlay;
return this;
}
public InsetDivider build() {
InsetDivider insetDivider = new InsetDivider();
if (mDividerHeight == 0) {
// Set default divider height to 1dp.
insetDivider.setDividerHeight(mContext.getResources().getDimensionPixelSize(R.dimen.divider_height));
} else if (mDividerHeight > 0) {
insetDivider.setDividerHeight(mDividerHeight);
} else {
throw new IllegalArgumentException("Divider's height can't be negative.");
}
insetDivider.setFirstInset(mFirstInset < 0 ? 0 : mFirstInset);
insetDivider.setSecondInset(mSecondInset < 0 ? 0 : mSecondInset);
if (mColor == 0) {
throw new IllegalArgumentException("Don't forget to set color");
} else {
insetDivider.setColor(mColor);
}
if (mOrientation != InsetDivider.HORIZONTAL_LIST && mOrientation != InsetDivider.VERTICAL_LIST) {
throw new IllegalArgumentException("Invalid orientation");
} else {
insetDivider.setOrientation(mOrientation);
}
insetDivider.setOverlay(mOverlay);
return insetDivider;
}
}
}
And you can use it like this:
ItemDecoration divider = new InsetDivider.Builder(this)
.orientation(InsetDivider.VERTICAL_LIST)
.dividerHeight(getResources().getDimensionPixelSize(R.dimen.divider_height))
.color(getResources().getColor(R.color.colorAccent))
.insets(getResources().getDimensionPixelSize(R.dimen.divider_inset), 0)
.overlay(true)
.build();
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.addItemDecoration(divider);
I also wrote a demo App about how to implement ItemDecoration and how to use them. You can check out my GitHub repo Dividers-For-RecyclerView. There are three implementations in it:
RegExp can be used on the input string not just technically but practically with the match
method too.
Because the output of the match()
is an array we need to retrieve the first array element of the result. When the match fails, the function returns null
. To avoid an exception error we will add the ||
conditional operator before accessing the first array element and test against the input
property that is a static property of regular expressions that contains the input string.
str = 'XYZ test';
switch (str) {
case (str.match(/^xyz/) || {}).input:
console.log("Matched a string that starts with 'xyz'");
break;
case (str.match(/test/) || {}).input:
console.log("Matched the 'test' substring");
break;
default:
console.log("Didn't match");
break;
}
Another approach is to use the String()
constructor to convert the resulting array that must have only 1 element (no capturing groups) and whole string must be captured with quanitifiers (.*
) to a string. In case of a failure the null
object will become a "null"
string. Not convenient.
str = 'haystack';
switch (str) {
case String(str.match(/^hay.*/)):
console.log("Matched a string that starts with 'hay'");
break;
}
Anyway, a more elegant solution is to use the /^find-this-in/.test(str)
with switch (true)
method which simply returns a boolean value and it's easier to search without case sensitivity.
[u'{email:[email protected],gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test,gem:0}', u'{email:test1,gem:0}']
'u' denotes unicode characters. We can easily remove this with map function on the final list element
map(str, test)
Another way is when you are appending it to the list
test.append(str(a))
Either something like this:
"abc" + str(9)
or
"abs{0}".format(9)
or
"abs%d" % (9,)
Both answers to this questions are correct, but I was still missing a complete, short solution to backup a Github repository into a local file. The gist is available here, feel free to fork or adapt to your needs.
backup.sh:
#!/bin/bash
# Backup the repositories indicated in the command line
# Example:
# bin/backup user1/repo1 user1/repo2
set -e
for i in $@; do
FILENAME=$(echo $i | sed 's/\//-/g')
echo "== Backing up $i to $FILENAME.bak"
git clone [email protected]:$i $FILENAME.git --mirror
cd "$FILENAME.git"
git bundle create ../$FILENAME.bak --all
cd ..
rm -rf $i.git
echo "== Repository saved as $FILENAME.bak"
done
restore.sh:
#!/bin/bash
# Restore the repository indicated in the command line
# Example:
# bin/restore filename.bak
set -e
FOLDER_NAME=$(echo $1 | sed 's/.bak//')
git clone --bare $1 $FOLDER_NAME.git
In Sql Server Management Studio:
just go to security->schema->dbo
.
Double click dbo, then click on permission tab->(blue font)view database permission
and feel free to scroll for required fields like "execute".
Help yourself to choose usinggrant
or deny
controls. Hope this will help:)
in my case i am add in manifest file `
tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"
application tag of course, It will work
Assuming you're on at least 3.2, there's a built in for this:
int.from_bytes( bytes, byteorder, *, signed=False )
...
The argument bytes must either be a bytes-like object or an iterable producing bytes.
The byteorder argument determines the byte order used to represent the integer. If byteorder is "big", the most significant byte is at the beginning of the byte array. If byteorder is "little", the most significant byte is at the end of the byte array. To request the native byte order of the host system, use sys.byteorder as the byte order value.
The signed argument indicates whether two’s complement is used to represent the integer.
## Examples:
int.from_bytes(b'\x00\x01', "big") # 1
int.from_bytes(b'\x00\x01', "little") # 256
int.from_bytes(b'\x00\x10', byteorder='little') # 4096
int.from_bytes(b'\xfc\x00', byteorder='big', signed=True) #-1024
Reason to that is with the new update, they changed the URL for the Android Developer Tools update site to require HTTPS. If you are updating ADT, make sure you use HTTPS in the URL for the Android Developer Tools update site.
You're obviously not closing your file descriptors before opening new ones. Are you on windows or linux?
What to do if :foo
in its natural form contains slashes? You wouldn't want it to Isn't that the distinction the recommendation is attempting to preserve? It specifically notes,
The similarity to unix and other disk operating system filename conventions should be taken as purely coincidental, and should not be taken to indicate that URIs should be interpreted as file names.
If one was building an online interface to a backup program, and wished to express the path as a part of the URL path, it would make sense to encode the slashes in the file path, as that is not really part of the hierarchy of the resource - and more importantly, the route. /backups/2016-07-28content//home/dan/
loses the root of the filesystem in the double slash. Escaping the slashes is the appropriate way to distinguish, as I read it.
Let me add my own answer, because I believe the others are missing the point of Docker.
Using VOLUME
in the Dockerfile is the Right Way™, because you let Docker know that a certain directory contains permanent data. Docker will create a volume for that data and never delete it, even if you remove all the containers that use it.
It also bypasses the union file system, so that the volume is in fact an actual directory that gets mounted (read-write or readonly) in the right place in all the containers that share it.
Now, in order to access that data from the host, you only need to inspect your container:
# docker inspect myapp
[{
.
.
.
"Volumes": {
"/var/www": "/var/lib/docker/vfs/dir/b3ef4bc28fb39034dd7a3aab00e086e6...",
"/var/cache/nginx": "/var/lib/docker/vfs/dir/62499e6b31cb3f7f59bf00d8a16b48d2...",
"/var/log/nginx": "/var/lib/docker/vfs/dir/71896ce364ef919592f4e99c6e22ce87..."
},
"VolumesRW": {
"/var/www": false,
"/var/cache/nginx": true,
"/var/log/nginx": true
}
}]
What I usually do is make symlinks in some standard place such as /srv, so that I can easily access the volumes and manage the data they contain (only for the volumes you care about):
ln -s /var/lib/docker/vfs/dir/b3ef4bc28fb39034dd7a3aab00e086e6... /srv/myapp-www
ln -s /var/lib/docker/vfs/dir/71896ce364ef919592f4e99c6e22ce87... /srv/myapp-log
File.getParent() from Java Documentation
you can swipe the key and the value. For example
String[] k = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil"};
int[] v = {341, 273, 278, 329, 445};
TreeMap<Integer,String>a=new TreeMap();
for (int i = 0; i < k.length; i++)
a.put(v[i],k[i]);
System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
a.remove(a.firstEntry().getKey());
System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
private void button1_Click(object sender, EventArgs e)
{
Form2 m = new Form2();
m.Show();
this.Visible = false;
}
Yes there is a way to do it.
First declare a class.
//anyfile.ts
export class Custom
{
name: string,
empoloyeeID: number
}
Then in your component import the class
import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
name: string;
empoloyeeID : number;
empList: Array<Custom> = [];
constructor() {
}
ngOnInit() {
}
onEmpCreate(){
//console.log(this.name,this.empoloyeeID);
let customObj = new Custom();
customObj.name = "something";
customObj.employeeId = 12;
this.empList.push(customObj);
this.name ="";
this.empoloyeeID = 0;
}
}
Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html
Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2
This is how to assign a value to a variable:
SELECT @EmpID = Id
FROM dbo.Employee
However, the above query is returning more than one value. You'll need to add a WHERE
clause in order to return a single Id
value.
Workbooks.Open
does work too.
Workbooks.Open ActiveWorkbook.Path & "\Temp.csv", Local:=True
this works/is needed because i use Excel in germany and excel does use "," to separate .csv by default because i use an english installation of windows. even if you use the code below excel forces the "," separator.
Workbooks.Open ActiveWorkbook.Path & "\Test.csv", , , 6, , , , , ";"
and Workbooks.Open ActiveWorkbook.Path & "\Temp.csv", , , 4
+variants of this do not work(!)
why do they even have the delimiter parameter if it is blocked by the Local parameter ?! this makes no sense at all. but now it works.

Here is a little something I cooked up today. Seems to work for me. Basically you override the Add method in your base namespace to do a check and then call the base's Add method in order to actually add it. Hope this works for you
using System;
using System.Collections.Generic;
using System.Collections;
namespace Main
{
internal partial class Dictionary<TKey, TValue> : System.Collections.Generic.Dictionary<TKey, TValue>
{
internal new virtual void Add(TKey key, TValue value)
{
if (!base.ContainsKey(key))
{
base.Add(key, value);
}
}
}
internal partial class List<T> : System.Collections.Generic.List<T>
{
internal new virtual void Add(T item)
{
if (!base.Contains(item))
{
base.Add(item);
}
}
}
public class Program
{
public static void Main()
{
Dictionary<int, string> dic = new Dictionary<int, string>();
dic.Add(1,"b");
dic.Add(1,"a");
dic.Add(2,"c");
dic.Add(1, "b");
dic.Add(1, "a");
dic.Add(2, "c");
string val = "";
dic.TryGetValue(1, out val);
Console.WriteLine(val);
Console.WriteLine(dic.Count.ToString());
List<string> lst = new List<string>();
lst.Add("b");
lst.Add("a");
lst.Add("c");
lst.Add("b");
lst.Add("a");
lst.Add("c");
Console.WriteLine(lst[2]);
Console.WriteLine(lst.Count.ToString());
}
}
}
My user account did not have the permissions to alter the database and table, as suggested in this solution.
If, like me, you don't care about the character collation (you are using the '=' operator), you can apply the reverse fix. Run this before your SELECT:
SET collation_connection = 'latin1_swedish_ci';
Just wanted to add an important piece of information that I believe was left out perhaps with the assumption that the ones seeking answers might already know. This problem happens a lot and I too found myself stuck when I tried to implement the viewAlert
method for the buttons of the UIAlertView
message. To do this you need to 1st add the delegate class which may look something like this:
@interface YourViewController : UIViewController <UIAlertViewDelegate>
Also you can find a very helpful tutorial here!
Hope this helps.
You can also copy a cell which contains the conditional formatting and then select the range (of destination document -or page-) where you want the conditional format to be applied and select "paste special" > "paste only conditional formatting"
For anyone trying to use jQuery.active with JSONP requests (like I was) you'll need enable it with this:
jQuery.ajaxPrefilter(function( options ) {
options.global = true;
});
Keep in mind that you'll need a timeout on your JSONP request to catch failures.
If you're currently on the branch you want to rename:
git branch -m new_name
Or else:
git branch -m old_name new_name
You can check with:
git branch -a
As you can see, only the local name changed Now, to change the name also in the remote you must do:
git push origin :old_name
This removes the branch, then upload it with the new name:
git push origin new_name
Arrays in JS have two types of properties:
Regular elements and associative properties (which are nothing but objects)
When you define a = new Array()
, you are defining an empty array. Note that there are no associative objects yet
When you define b = new Array(2)
, you are defining an array with two undefined locations.
In both your examples of 'a' and 'b', you are adding associative properties i.e. objects to these arrays.
console.log (a)
or console.log(b)
prints the array elements i.e. []
and [undefined, undefined]
respectively. But since a1/a2
and b1/b2
are associative objects inside their arrays, they can be logged only by console.log(a.a1, a.a2)
kind of syntax

How to print unicode characters into a file:
Save this to file: foo.py:
#!/usr/bin/python -tt
# -*- coding: utf-8 -*-
import codecs
import sys
UTF8Writer = codecs.getwriter('utf8')
sys.stdout = UTF8Writer(sys.stdout)
print(u'e with obfuscation: é')
Run it and pipe output to file:
python foo.py > tmp.txt
Open tmp.txt and look inside, you see this:
el@apollo:~$ cat tmp.txt
e with obfuscation: é
Thus you have saved unicode e with a obfuscation mark on it to a file.
There is no built in way to do this accurately in idiomatic-c#. There are some workarounds, such as this CodeProject example that people have coded though.
make the image the exact size needed in the email. Windows MSO has a hard time resizing images in different scenarios.
in the case of using a 1px by 1px transparent png or gif as a spacer, defining the dimensions via width, height, or style attributes will work as expected in the majority of clients, but not windows MSO (of course).
example use case - you are using a background image and need to position a with a link inside over some part of the background image. Using a 1px by 1px spacer gif/png will only expand so wide (about 30px). You need size the spacer to the exact dimensions.
Do you mean just this:
SELECT Count(*) FROM YourTable WHERE Position = 'Manager'
If so, then yup that works!
It looks like you would do something like this:

void writer()
{
// get upgradable access
boost::upgrade_lock<boost::shared_mutex> lock(_access);
// get exclusive access
boost::upgrade_to_unique_lock<boost::shared_mutex> uniqueLock(lock);
// now we have exclusive access

You need to run the server first. The command you use (in the question) starts a client to connect to the server but the server is not there so there the error.
Since I am not a Windows user (Linux comes equipped) so I might not be the best person to tell you how but I can point to you to a guide and another guide that show you how to get MySQL server up and running in Windows.
After you get that running, you can use the command (in the question) to connect it.
NOTE: You may also try http://www.apachefriends.org/en/xampp.html if you plan to use MySQL for web database development.
Hope this helps.

One thing that I have to add is that there is no reference in C.
Secondly, this is the language syntax convention. & - is an address operator but it also mean a reference - all depends on usa case
If there was some "reference" keyword instead of & you could write
int CDummy::isitme (reference CDummy param)
but this is C++ and we should accept it advantages and disadvantages...

(Spoiler: accept
attribute is not bulletproof solution)
required
is a reflected property (like id
, name
, type
, and such), so:
element.required = true;
...where element
is the actual input
DOM element, e.g.:
document.getElementById("edName").required = true;
(Just for completeness.)
Re:
Then the attribute's value is not the empty string, nor the canonical name of the attribute:
edName.attributes.required = [object Attr]
That's because required
in that code is an attribute object, not a string; attributes
is a NamedNodeMap
whose values are Attr
objects. To get the value of one of them, you'd look at its value
property. But for a boolean attribute, the value isn't relevant; the attribute is either present in the map (true) or not present (false).
So if required
weren't reflected, you'd set it by adding the attribute:
element.setAttribute("required", "");
...which is the equivalent of element.required = true
. You'd clear it by removing it entirely:
element.removeAttribute("required");
...which is the equivalent of element.required = false
.
But we don't have to do that with required
, since it's reflected.
I did this in 1.9.1 (to delete the last or latest migration created):
rm <appname>/migrations/<migration #>*
example: rm myapp/migrations/0011*
logged into database and ran this SQL (postgres in this example)
delete from django_migrations where name like '0011%';
I was then able to create new migrations that started with the migration number that I had just deleted (in this case, 11).
Okay this is how datatypes work in Java. (You have to excuse my English, I am prob. not using the right vocab. You have to differentiate between two of them. The base datatypes and the normal datatypes. Base data types pretty much make up everything that exists. For example, there are all numbers, char, boolean etc. The normal data types or complex data types is everything else. A String is an array of chars, therefore a complex data type.
Every variable that you create is actually a pointer on the value in your memory. For example:
String s = new String("This is just a test");
the variable "s" does NOT contain a String. It is a pointer. This pointer points on the variable in your memory.
When you call System.out.println(anyObject)
, the toString()
method of that object is called. If it did not override toString
from Object, it will print the pointer.
For example:
public class Foo{
public static void main(String[] args) {
Foo f = new Foo();
System.out.println(f);
}
}
>>>>
>>>>
>>>>Foo@330bedb4
Everything behind the "@" is the pointer. This only works for complex data types. Primitive datatypes are DIRECTLY saved in their pointer. So actually there is no pointer and the values are stored directly.
For example:
int i = 123;
i does NOT store a pointer in this case. i will store the integer value 123 (in byte ofc).
Okay so lets come back to the ==
operator.
It always compares the pointer and not the content saved at the pointer's position in the memory.
Example:
String s1 = new String("Hallo");
String s2 = new String("Hallo");
System.out.println(s1 == s2);
>>>>> false
This both String have a different pointer. String.equals(String other) however compares the content. You can compare primitive data types with the '==' operator because the pointer of two different objects with the same content is equal.
Null would mean that the pointer is empty. An empty primitive data type by default is 0 (for numbers). Null for any complex object however means, that object does not exist.

in your terminal window and it will show you exactly where it was installed.
There is a library called BoofCV which claims to better than ZBar and other libraries.
Here are the steps to use that (any OS).
Pre-requisites:
pip install pyboof
Class to decode:
import os
import numpy as np
import pyboof as pb
pb.init_memmap() #Optional
class QR_Extractor:
# Src: github.com/lessthanoptimal/PyBoof/blob/master/examples/qrcode_detect.py
def __init__(self):
self.detector = pb.FactoryFiducial(np.uint8).qrcode()
def extract(self, img_path):
if not os.path.isfile(img_path):
print('File not found:', img_path)
return None
image = pb.load_single_band(img_path, np.uint8)
self.detector.detect(image)
qr_codes = []
for qr in self.detector.detections:
qr_codes.append({
'text': qr.message,
'points': qr.bounds.convert_tuple()
})
return qr_codes
Usage:
qr_scanner = QR_Extractor()
output = qr_scanner.extract('Your-Image.jpg')
print(output)
Tested and works on Python 3.8 (Windows & Ubuntu)
One way you can do this, is to Keep track of the current selected position in your activity:
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
currentPosition = position
lv_cli.notifyDataSetChanged();
}
Now, be sure you assign an ID to the parent layout (linearLayout, boxLayout, relativeLayout, .. Whatever you prefer) of your list item.
Then in your ListView you can do something Like this:
layoutBackground = (LinearLayout) convertView.findViewById(R.id.layout_background);
if (YourActivity.this.currentPosition == position) {
layoutBackground.setBackgroundColor(YourActivity.this.getResources().getColor(R.color.hilight_color));
} else{
layoutBackground.setBackgroundResource(R.drawable.list_item_drawable);
}
Basically, you just set the hilight color to the layout as a background when it equals your current selected position. Notice how I set a drawable background resource when the item is not selected. This could be in your case different (since you posted no code). In my case, this drawable is a selector which makes sure the item is hi-lighted when pressed.
NOTE: This simple code doesn't use a view-holder, but I really recommend using one.
Take a look at ISO 11179-5: Naming and identification principles You can get it here: http://metadata-standards.org/11179/#11179-5
I blogged about it a while back here: ISO-11179 Naming Conventions
I was getting this error with Laravel Sanctum. I fixed it by adding \Illuminate\Session\Middleware\StartSession::class,
to the api
middleware group in Kernel.php, but I later figured out this "worked" because my authentication routes were added in api.php
instead of web.php
, so Laravel was using the wrong auth guard.
I moved these routes here into web.php
and then they started working properly with the AuthenticatesUsers.php
trait:
Route::group(['middleware' => ['guest', 'throttle:10,5']], function () {
Route::post('register', 'Auth\RegisterController@register')->name('register');
Route::post('login', 'Auth\LoginController@login')->name('login');
Route::post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail');
Route::post('password/reset', 'Auth\ResetPasswordController@reset');
Route::post('email/verify/{user}', 'Auth\VerificationController@verify')->name('verification.verify');
Route::post('email/resend', 'Auth\VerificationController@resend');
Route::post('oauth/{driver}', 'Auth\OAuthController@redirectToProvider')->name('oauth.redirect');
Route::get('oauth/{driver}/callback', 'Auth\OAuthController@handleProviderCallback')->name('oauth.callback');
});
Route::post('logout', 'Auth\LoginController@logout')->name('logout');
I figured out the problem after I got another weird error about RequestGuard::logout()
does not exist.
It made me realize that my custom auth routes are calling methods from the AuthenticatesUsers trait, but I wasn't using Auth::routes()
to accomplish it. Then I realized Laravel uses the web guard by default and that means routes should be in routes/web.php
.
This is what my settings look like now with Sanctum and a decoupled Vue SPA app:
Kernel.php
protected $middlewareGroups = [
'web' => [
\App\Http\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
// \Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\App\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
],
'api' => [
EnsureFrontendRequestsAreStateful::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
'throttle:60,1',
],
];
Note: With Laravel Sanctum and same-domain Vue SPA, you use httpOnly cookies for session cookie, and remember me cookie, and unsecure cookie for CSRF, so you use the
web
guard for auth, and every other protected, JSON-returning route should useauth:sanctum
middleware.
config/auth.php
'defaults' => [
'guard' => 'web',
'passwords' => 'users',
],
...
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
'api' => [
'driver' => 'token',
'provider' => 'users',
'hash' => false,
],
],
Then you can have unit tests such as this, where critically, Auth::check()
, Auth::user()
, and Auth::logout()
work as expected with minimal config and maximal usage of AuthenticatesUsers
and RegistersUsers
traits.
Here are a couple of my login unit tests:
TestCase.php
/**
* Creates and/or returns the designated regular user for unit testing
*
* @return \App\User
*/
public function user() : User
{
$user = User::query()->firstWhere('email', '[email protected]');
if ($user) {
return $user;
}
// User::generate() is just a wrapper around User::create()
$user = User::generate('Test User', '[email protected]', self::AUTH_PASSWORD);
return $user;
}
/**
* Resets AuthManager state by logging out the user from all auth guards.
* This is used between unit tests to wipe cached auth state.
*
* @param array $guards
* @return void
*/
protected function resetAuth(array $guards = null) : void
{
$guards = $guards ?: array_keys(config('auth.guards'));
foreach ($guards as $guard) {
$guard = $this->app['auth']->guard($guard);
if ($guard instanceof SessionGuard) {
$guard->logout();
}
}
$protectedProperty = new \ReflectionProperty($this->app['auth'], 'guards');
$protectedProperty->setAccessible(true);
$protectedProperty->setValue($this->app['auth'], []);
}
LoginTest.php
protected $auth_guard = 'web';
/** @test */
public function it_can_login()
{
$user = $this->user();
$this->postJson(route('login'), ['email' => $user->email, 'password' => TestCase::AUTH_PASSWORD])
->assertStatus(200)
->assertJsonStructure([
'user' => [
...expectedUserFields,
],
]);
$this->assertEquals(Auth::check(), true);
$this->assertEquals(Auth::user()->email, $user->email);
$this->assertAuthenticated($this->auth_guard);
$this->assertAuthenticatedAs($user, $this->auth_guard);
$this->resetAuth();
}
/** @test */
public function it_can_logout()
{
$this->actingAs($this->user())
->postJson(route('logout'))
->assertStatus(204);
$this->assertGuest($this->auth_guard);
$this->resetAuth();
}
I overrided the registered
and authenticated
methods in the Laravel auth traits so that they return the user object instead of just the 204 OPTIONS:
public function authenticated(Request $request, User $user)
{
return response()->json([
'user' => $user,
]);
}
protected function registered(Request $request, User $user)
{
return response()->json([
'user' => $user,
]);
}
Look at the vendor code for the auth traits. You can use them untouched, plus those two above methods.
Here is my Vue SPA's Vuex actions for login:
async login({ commit }, credentials) {
try {
const { data } = await axios.post(route('login'), {
...credentials,
remember: credentials.remember || undefined,
});
commit(FETCH_USER_SUCCESS, { user: data.user });
commit(LOGIN);
return commit(CLEAR_INTENDED_URL);
} catch (err) {
commit(LOGOUT);
throw new Error(`auth/login# Problem logging user in: ${err}.`);
}
},
async logout({ commit }) {
try {
await axios.post(route('logout'));
return commit(LOGOUT);
} catch (err) {
commit(LOGOUT);
throw new Error(`auth/logout# Problem logging user out: ${err}.`);
}
},
It took me over a week to get Laravel Sanctum + same-domain Vue SPA + auth unit tests all working up to my standard, so hopefully my answer here can help save others time in the future.
When I'm working with csv
files, I often use the pandas library. It makes things like this very easy. For example:
import pandas as pd
a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)
Some explanation follows. First, we read in the csv files:
>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a
title stage jan feb
0 darn 3.001 0.421 0.532
1 ok 2.829 1.036 0.751
2 three 1.115 1.146 2.921
>>> b
title mar apr may jun Unnamed: 5
0 darn 0.631 1.321 0.951 1.7510 NaN
1 ok 1.001 0.247 2.456 0.3216 NaN
2 three 0.285 1.283 0.924 956.0000 NaN
and we see there's an extra column of data (note that the first line of fileb.csv
-- title,mar,apr,may,jun,
-- has an extra comma at the end). We can get rid of that easily enough:
>>> b = b.dropna(axis=1)
>>> b
title mar apr may jun
0 darn 0.631 1.321 0.951 1.7510
1 ok 1.001 0.247 2.456 0.3216
2 three 0.285 1.283 0.924 956.0000
Now we can merge a
and b
on the title column:
>>> merged = a.merge(b, on='title')
>>> merged
title stage jan feb mar apr may jun
0 darn 3.001 0.421 0.532 0.631 1.321 0.951 1.7510
1 ok 2.829 1.036 0.751 1.001 0.247 2.456 0.3216
2 three 1.115 1.146 2.921 0.285 1.283 0.924 956.0000
and finally write this out:
>>> merged.to_csv("output.csv", index=False)
producing:
title,stage,jan,feb,mar,apr,may,jun
darn,3.001,0.421,0.532,0.631,1.321,0.951,1.751
ok,2.829,1.036,0.751,1.001,0.247,2.456,0.3216
three,1.115,1.146,2.921,0.285,1.283,0.924,956.0
Useful for passing array of error messages to View, perhaps via Json:
messageArray = this.ViewData.ModelState.Values.SelectMany(modelState => modelState.Errors, (modelState, error) => error.ErrorMessage).ToArray();
Private members are accessible only within the body of the class or the struct in which they are declared.
Internal types or members are accessible only within files in the same assembly
Things get messy quickly if you are talking about checked-in code in an enterprise environment. We've found that the best approach is to have the web.Release.config contain the following:
<system.web>
<compilation xdt:Transform="RemoveAttributes(debug)" />
<authentication>
<forms xdt:Transform="Replace" timeout="20" requireSSL="true" />
</authentication>
</system.web>
That way, developers are not affected (running in Debug), and only servers that get Release builds are requiring cookies to be SSL.
A simple solution is to use Microsoft ASP.NET Web API 2.2 Client
from NuGet.
Then you can simply do this and it'll serialize the object to JSON and set the Content-Type
header to application/json; charset=utf-8
:
var data = new
{
name = "Foo",
category = "article"
};
var client = new HttpClient();
client.BaseAddress = new Uri(baseUri);
client.DefaultRequestHeaders.Add("token", token);
var response = await client.PostAsJsonAsync("", data);
Thanks a ton for Bhaskar Karambelkar's answer which explains in detail and fixed my issue. But also I would like to re phrase the answer in three simple steps for someone who is in a hurry to fix
wsdlLocation= "http://localhost/wsdl/yourwsdlname.wsdl"
Create an xml file jax-ws-catalog.xml under META-INF as below
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"
prefer="system">
<system systemId="http://localhost/wsdl/yourwsdlname.wsdl" uri="wsdl/yourwsdlname.wsdl" />
</catalog>
Now package your jar. No more reference to the local directory, it's all packaged and referenced within
The issue I had is that sometimes I will need to get at a value that is deeply
nested. Normally you would need to do a type assertion at each level, so I went
ahead and just made a method that takes a map[string]interface{}
and a
string
key, and returns the resulting map[string]interface{}
.
The issue that cropped up for me was that at some depths you will encounter a Slice instead of Map. So I also added methods to return a Slice from Map, and Map from Slice. I didnt do one for Slice to Slice, but you could easily add that if needed. Here are the methods:
package main
type Slice []interface{}
type Map map[string]interface{}
func (m Map) M(s string) Map {
return m[s].(map[string]interface{})
}
func (m Map) A(s string) Slice {
return m[s].([]interface{})
}
func (a Slice) M(n int) Map {
return a[n].(map[string]interface{})
}
and example code:
package main
import (
"encoding/json"
"fmt"
"log"
"os"
)
func main() {
o, e := os.Open("a.json")
if e != nil {
log.Fatal(e)
}
in_m := Map{}
json.NewDecoder(o).Decode(&in_m)
out_m := in_m.
M("contents").
M("sectionListRenderer").
A("contents").
M(0).
M("musicShelfRenderer").
A("contents").
M(0).
M("musicResponsiveListItemRenderer").
M("navigationEndpoint").
M("browseEndpoint")
fmt.Println(out_m)
}
For anyone interested, here's a trivial conversion of Joshua's Javascript code to Objective-C:
- (double)distanceToPoint:(CGPoint)p fromLineSegmentBetween:(CGPoint)l1 and:(CGPoint)l2
{
double A = p.x - l1.x;
double B = p.y - l1.y;
double C = l2.x - l1.x;
double D = l2.y - l1.y;
double dot = A * C + B * D;
double len_sq = C * C + D * D;
double param = dot / len_sq;
double xx, yy;
if (param < 0 || (l1.x == l2.x && l1.y == l2.y)) {
xx = l1.x;
yy = l1.y;
}
else if (param > 1) {
xx = l2.x;
yy = l2.y;
}
else {
xx = l1.x + param * C;
yy = l1.y + param * D;
}
double dx = p.x - xx;
double dy = p.y - yy;
return sqrtf(dx * dx + dy * dy);
}
I needed this solution to work with MKMapPoint
so I will share it in case someone else needs it. Just some minor change and this will return the distance in meters :
- (double)distanceToPoint:(MKMapPoint)p fromLineSegmentBetween:(MKMapPoint)l1 and:(MKMapPoint)l2
{
double A = p.x - l1.x;
double B = p.y - l1.y;
double C = l2.x - l1.x;
double D = l2.y - l1.y;
double dot = A * C + B * D;
double len_sq = C * C + D * D;
double param = dot / len_sq;
double xx, yy;
if (param < 0 || (l1.x == l2.x && l1.y == l2.y)) {
xx = l1.x;
yy = l1.y;
}
else if (param > 1) {
xx = l2.x;
yy = l2.y;
}
else {
xx = l1.x + param * C;
yy = l1.y + param * D;
}
return MKMetersBetweenMapPoints(p, MKMapPointMake(xx, yy));
}
Only this worked for me:
#container:hover .cube { background-color: yellow; }
Where .cube
is CssClass of the #cube
.
Tested in Firefox, Chrome and Edge.
A little late, but if any of you have been going crazy trying to use inline SVG as a background, the escaping suggestions above do not quite work. For one, it does not work in IE, and depending on the content of your SVG the technique will cause trouble in other browsers, like FF.
If you base64 encode the svg (not the entire url, just the svg tag and its contents! ) it works in all browsers. Here is the same jsfiddle example in base64: http://jsfiddle.net/vPA9z/3/
The CSS now looks like this:
body { background-image:
url("data:image/svg+xml;base64,PHN2ZyB4bWxucz0naHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmcnIHdpZHRoPScxMCcgaGVpZ2h0PScxMCc+PGxpbmVhckdyYWRpZW50IGlkPSdncmFkaWVudCc+PHN0b3Agb2Zmc2V0PScxMCUnIHN0b3AtY29sb3I9JyNGMDAnLz48c3RvcCBvZmZzZXQ9JzkwJScgc3RvcC1jb2xvcj0nI2ZjYycvPiA8L2xpbmVhckdyYWRpZW50PjxyZWN0IGZpbGw9J3VybCgjZ3JhZGllbnQpJyB4PScwJyB5PScwJyB3aWR0aD0nMTAwJScgaGVpZ2h0PScxMDAlJy8+PC9zdmc+");
Remember to remove any URL escaping before converting to base64. In other words, the above example showed color='#fcc' converted to color='%23fcc', you should go back to #.
The reason why base64 works better is that it eliminates all the issues with single and double quotes and url escaping
If you are using JS, you can use window.btoa()
to produce your base64 svg; and if it doesn't work (it might complain about invalid characters in the string), you can simply use https://www.base64encode.org/.
Example to set a div background:
var mySVG = "<svg xmlns='http://www.w3.org/2000/svg' width='10' height='10'><linearGradient id='gradient'><stop offset='10%' stop-color='#F00'/><stop offset='90%' stop-color='#fcc'/> </linearGradient><rect fill='url(#gradient)' x='0' y='0' width='100%' height='100%'/></svg>";_x000D_
var mySVG64 = window.btoa(mySVG);_x000D_
document.getElementById('myDiv').style.backgroundImage = "url('data:image/svg+xml;base64," + mySVG64 + "')";
_x000D_
html, body, #myDiv {_x000D_
width: 100%;_x000D_
height: 100%;_x000D_
margin: 0;_x000D_
}
_x000D_
<div id="myDiv"></div>
_x000D_
With JS you can generate SVGs on the fly, even changing its parameters.
One of the better articles on using SVG is here : http://dbushell.com/2013/02/04/a-primer-to-front-end-svg-hacking/
Hope this helps

(or you can specify any other range to look in)
If you are using c# on the desktop, you can use SimpleMapi. That way it will be sent using the default mail client, and the user has the option of reviewing the message before sending, just like mailto:
.
To use it you add the Simple-MAPI.NET package (it's 13Kb), and run:
var mapi = new SimpleMapi();
mapi.AddRecipient(null, address, false);
mapi.Attach(path);
//mapi.Logon(ParentForm.Handle); //not really necessary
mapi.Send(subject, body, true);
There is a significant different in how jQuery handles the this variable with a "on" method
$("outer DOM element").on('click',"inner DOM element",function(){
$(this) // refers to the "inner DOM element"
})
If you compare this with :-
$("outer DOM element").click(function(){
$(this) // refers to the "outer DOM element"
})
For clarification, here is a more detailed example demonstrating Form Validation using jQuery Validation Unobtrusive.
Both use the following JavaScript with jQuery:
$("#commentForm").validate({
submitHandler: function(form) {
// some other code
// maybe disabling submit button
// then:
alert("This is a valid form!");
// form.submit();
}
});
The main differences between the two plugins are the attributes used for each approach.
jQuery Validation
Simply use the following attributes:
Here's the form...
<form id="commentForm">
<label for="form-name">Name (required, at least 2 characters)</label>
<input id="form-name" type="text" name="form-name" class="form-control" minlength="2" required>
<input type="submit" value="Submit">
</form>
jQuery Validation Unobtrusive
The following data attributes are needed:
Here's the form...
<form id="commentForm">
<label for="form-x-name">Name (required, at least 2 characters)</label>
<input id="form-x-name" type="text" name="name" minlength="2" class="form-control" data-msg-required="Name is required." data-rule-required="true">
<input type="submit" value="Submit">
</form>
Based on either of these examples, if the form fields that are required have been filled, and they meet the additional attribute criteria, then a message will pop up notifying that all form fields are validated. Otherwise, there will be text near the offending form fields that indicates the error.

Mapped to CoffeeScript if anyones interested. **edit -> sorry using backbone too, but you get the idea.
Modified slightly to accept a beacon with attribs
{latitude: item.lat,longitude: item.lng,date: new Date(item.effective_at),accuracy: item.gps_accuracy}
MIN_ACCURACY = 1
# mapped from http://stackoverflow.com/questions/1134579/smooth-gps-data
class v.Map.BeaconFilter
constructor: ->
_.extend(this, Backbone.Events)
process: (decay,beacon) ->
accuracy = Math.max beacon.accuracy, MIN_ACCURACY
unless @variance?
# if variance nil, inititalise some values
@variance = accuracy * accuracy
@timestamp_ms = beacon.date.getTime();
@lat = beacon.latitude
@lng = beacon.longitude
else
@timestamp_ms = beacon.date.getTime() - @timestamp_ms
if @timestamp_ms > 0
# time has moved on, so the uncertainty in the current position increases
@variance += @timestamp_ms * decay * decay / 1000;
@timestamp_ms = beacon.date.getTime();
# Kalman gain matrix K = Covarariance * Inverse(Covariance + MeasurementVariance)
# NB: because K is dimensionless, it doesn't matter that variance has different units to lat and lng
_k = @variance / (@variance + accuracy * accuracy)
@lat = _k * (beacon.latitude - @lat)
@lng = _k * (beacon.longitude - @lng)
@variance = (1 - _k) * @variance
[@lat,@lng]
The best way to do it is by using git diff
in the following way:
git diff <source_branch> <target_branch> -- file_path
It will check the difference between files in those branches. Take a look at this article for more information about git commands and how they work.
Try this:
<?php
$handle = fopen ("specialchars.csv","r");
echo '<table border="1"><tr><td>First name</td><td>Last name</td></tr><tr>';
while ($data = fgetcsv ($handle, 1000, ";")) {
$data = array_map("utf8_encode", $data); //added
$num = count ($data);
for ($c=0; $c < $num; $c++) {
// output data
echo "<td>$data[$c]</td>";
}
echo "</tr><tr>";
}
?>
Just as a tidbit:
Even (
((A)null)
instanceof A)
will return false
.
(If typecasting null
seems surprising, sometimes you have to do it, for example in situations like this:
public class Test
{
public static void test(A a)
{
System.out.println("a instanceof A: " + (a instanceof A));
}
public static void test(B b) {
// Overloaded version. Would cause reference ambiguity (compile error)
// if Test.test(null) was called without casting.
// So you need to call Test.test((A)null) or Test.test((B)null).
}
}
So Test.test((A)null)
will print a instanceof A: false
.)
P.S.: If you are hiring, please don't use this as a job interview question. :D
With CSS you can simulate object-fit: [cover|contain];
. It's use transform
and [max|min]-[width|height]
.
It's not perfect. That not work in one case: if the image is wider and shorter than the container.

I had the same issue. After changing a semicolon in the php.ini file I solved my problem. Let's see how can you solve it?
First, open php.ini file. xampp/php/php.ini
Search extension=imap
remove semicolon before extension and save this file.
Code before remove semicolon ;extension=imap
Code after remove semicolon extension=imap
Finally, open the XAMPP Control panel and restart Apache.
Caling .Value2
is an expensive operation because it's a COM-interop call. I would instead read the entire range into an array and then loop through the array:
object[,] data = Range.Value2;
// Create new Column in DataTable
for (int cCnt = 1; cCnt <= Range.Columns.Count; cCnt++)
{
textBox3.Text = cCnt.ToString();
var Column = new DataColumn();
Column.DataType = System.Type.GetType("System.String");
Column.ColumnName = cCnt.ToString();
DT.Columns.Add(Column);
// Create row for Data Table
for (int rCnt = 1; rCnt <= Range.Rows.Count; rCnt++)
{
textBox2.Text = rCnt.ToString();
string CellVal = String.Empty;
try
{
cellVal = (string)(data[rCnt, cCnt]);
}
catch (Microsoft.CSharp.RuntimeBinder.RuntimeBinderException)
{
ConvertVal = (double)(data[rCnt, cCnt]);
cellVal = ConvertVal.ToString();
}
DataRow Row;
// Add to the DataTable
if (cCnt == 1)
{
Row = DT.NewRow();
Row[cCnt.ToString()] = cellVal;
DT.Rows.Add(Row);
}
else
{
Row = DT.Rows[rCnt + 1];
Row[cCnt.ToString()] = cellVal;
}
}
}
Try this:
MessageBox.Show("Some text", "Some title",
MessageBoxButtons.OK, MessageBoxIcon.Error);
Include javascript using script tags just before your ending body tag. Preferably you will want to put it in a separate file and link to it to keep things a little more organized and easier to read. Theres a simple article here that will show you how http://www.selftaughtweb.com/how-to-include-javascript/
just put Wait() to wait until task completed

In market client on phones at least featured apps with high ratings get to display the promotional graphic.
This is the one that shows up on top even before you start searching the market for a specific app.
See this answer from Android market forum.
Edited: One of the google employee gives some clarifications here
Update: Both links above are now broken but the detailed information can be found here
Selected applications have the ability to be featured atop their respective categories. This is not a guaranteed feature, but uploading promotional graphics is something that we recommend.
Vertical align bottom and remove the float seems to work. I then had a margin issue, but the -2px keeps them from getting pushed down (and they still don't overlap)
.profile-header > div {
display: inline-block;
vertical-align: bottom;
float: none;
margin: -2px;
}
.profile-header {
margin-bottom:20px;
border:2px solid green;
display: table-cell;
}
.profile-pic {
height:300px;
border:2px solid red;
}
.profile-about {
border:2px solid blue;
}
.profile-about2 {
border:2px solid pink;
}
Example here: http://www.bootply.com/125740#
The problem with most solutions here is that they rewind the stack. This can be a big problem in some cases.In this example I show how to use iterators in different way to simulate real sleep
In this example the generator is calling it's own next()
so once it's going, it's on his own.
var h=a();
h.next().value.r=h; //that's how U run it, best I came up with
//sleep without breaking stack !!!
function *a(){
var obj= {};
console.log("going to sleep....2s")
setTimeout(function(){obj.r.next();},2000)
yield obj;
console.log("woke up");
console.log("going to sleep no 2....2s")
setTimeout(function(){obj.r.next();},2000)
yield obj;
console.log("woke up");
console.log("going to sleep no 3....2s")
setTimeout(function(){obj.r.next();},2000)
yield obj;
console.log("done");
}
You're pretty much right about cout
and cin
. They are objects (not functions) defined inside the std
namespace. Here are their declarations as defined by the C++ standard:
Header
<iostream>
synopsis#include <ios> #include <streambuf> #include <istream> #include <ostream> namespace std { extern istream cin; extern ostream cout; extern ostream cerr; extern ostream clog; extern wistream wcin; extern wostream wcout; extern wostream wcerr; extern wostream wclog; }
::
is known as the scope resolution operator. The names cout
and cin
are defined within std
, so we have to qualify their names with std::
.
Classes behave a little like namespaces in that the names declared inside the class belong to the class. For example:
class foo
{
public:
foo();
void bar();
};
The constructor named foo
is a member of the class named foo
. They have the same name because its the constructor. The function bar
is also a member of foo
.
Because they are members of foo
, when referring to them from outside the class, we have to qualify their names. After all, they belong to that class. So if you're going to define the constructor and bar
outside the class, you need to do it like so:
foo::foo()
{
// Implement the constructor
}
void foo::bar()
{
// Implement bar
}
This is because they are being defined outside the class. If you had not put the foo::
qualification on the names, you would be defining some new functions in the global scope, rather than as members of foo
. For example, this is entirely different bar
:
void bar()
{
// Implement different bar
}
It's allowed to have the same name as the function in the foo
class because it's in a different scope. This bar
is in the global scope, whereas the other bar
belonged to the foo
class.
slice does not change original array it return new array but splice changes the original array.
example: var arr = [1,2,3,4,5,6,7,8];
arr.slice(1,3); // output [2,3] and original array remain same.
arr.splice(1,3); // output [2,3,4] and original array changed to [1,5,6,7,8].
splice method second argument is different from slice method. second argument in splice represent count of elements to remove and in slice it represent end index.
arr.splice(-3,-1); // output [] second argument value should be greater then
0.
arr.splice(-3,-1); // output [6,7] index in minus represent start from last.
-1 represent last element so it start from -3 to -1. Above are major difference between splice and slice method.
Rather than using a proxy, I'm using the Firefox plugin "Modify Headers" to insert headers (in my case, to fake a login using the Single Sign On so I can test as different people).
Set the GroupName
property of both radio buttons to the same value. You could also try using a RadioButtonGroup
, which does this for you automatically.
NOTE: This won't work in IE
var ob = {
p: "ob.p"
}
var p = "window.p";
setTimeout(function(){
console.log(this.p); // will print "window.p"
},1000);
setTimeout(function(){
console.log(this.p); // will print "ob.p"
}.bind(ob),1000);
fruits.shift(); // Removes the first element from an array and returns only that element.
fruits.pop(); // Removes the last element from an array and returns only that element.
Just do that: getTabAt(index of your tab)
ActionBar actionBar = getSupportActionBar();
actionBar.selectTab(actionBar.getTabAt(0));
For me this issue was appearing due to the WWRD cert -- Mine was up to date but for some reason it was set to 'always trust' instead of 'use system default', which apparently makes a difference.
I've created an NPM module, which allows you to share locally-stored data across domains: https://www.npmjs.com/package/cookie-toss
By using an iframe hosted on Domain A, you can store all of your user data on Domain A, and reference that data by posting requests to the Domain A iframe.
Thus, Domains B, C, etc. can inject the iframe and post requests to it to store and access the desired data. Domain A becomes the hub for all shared data.
With a domain whitelist inside of Domain A, you can ensure only your dependent sites can access the data on Domain A.
The trick is to have the code inside of the iframe on Domain A which is able to recognize which data is being requested. The README in the above NPM module goes more in depth into the procedure.
Hope this helps!

Then, the output of fscanf

In some cases, there is no difference in file versions, but only in indentation, spacing, line ending or line numbers.
To patch despite those differences, it's possible to use the following two arguments :
--ignore-whitespace : It ignores whitespace differences (indentation, etc).
--fuzz 3 : the "--fuzz X" option sets the maximum fuzz factor to lines. This option only applies to context and unified diffs; it ignores up to X lines while looking for the place to install a hunk. Note that a larger fuzz factor increases the odds of making a faulty patch. The default fuzz factor is 2; there is no point to setting it to more than the number of lines of context in the diff, ordinarily 3.
Don't forget to user "--dry-run" : It'll try the patch without applying it.
Example :
patch --verbose --dry-run --ignore-whitespace --fuzz 3 < /path/to/patch.patch
More informations about Fuzz :
https://www.gnu.org/software/diffutils/manual/html_node/Inexact.html
Yes, it is possible:
public class Foo {
private int x;
public Foo() {
this(1);
}
public Foo(int x) {
this.x = x;
}
}
To chain to a particular superclass constructor instead of one in the same class, use super
instead of this
. Note that you can only chain to one constructor, and it has to be the first statement in your constructor body.
See also this related question, which is about C# but where the same principles apply.
Not necessarily better, but since it's nice to have options here's how to do it using Jinja statements:
- debug:
msg: "{% for address in network.addresses.private_man %}\
{% if address.type == 'fixed' %}\
{{ address.addr }}\
{% endif %}\
{% endfor %}"
Or if you prefer to put it all on one line:
- debug:
msg: "{% for address in network.addresses.private_man if address.type == 'fixed' %}{{ address.addr }}{% endfor %}"
Which returns:
ok: [localhost] => {
"msg": "172.16.1.100"

We are developing Versile Python (VPy), an implementation for python 2.6+ and 3.x of a new ORB/RPC framework. Functional AGPL dev releases for review and testing are available. VPy has native python capabilities similar to PyRo and RPyC via a general native objects layer (code example). The product is designed for platform-independent remote object interaction for implementations of Versile Platform.
Full disclosure: I work for the company developing VPy.

You can create a .a
file using the ar
utility, like so:
ar crf lib/libHeader.a header.o
lib
is a directory that contains all your libraries. it is good practice to organise your code this way and separate the code and the object files. Having everything in one directory generally looks ugly. The above line creates libHeader.a
in the directory lib
. So, in your current directory, do:
mkdir lib
Then run the above ar
command.
When linking all libraries, you can do it like so:
g++ test.o -L./lib -lHeader -o test
The -L
flag will get g++
to add the lib/
directory to the path. This way, g++
knows what directory to search when looking for libHeader
. -llibHeader
flags the specific library to link.
where test.o is created like so:
g++ -c test.cpp -o test.o

You might be interested in this list of HTML5 elements and attributes.
Also, please note that it's "HTML 4", not "HTML4". Indeed, for HTML 5, both variants are used, but there is an important difference in meaning. HTML 5 refers to the name of the W3C specification, whereas "HTML5" is the document type of those HTML files with a text/html
MIME type that follow this spec.
The same goes for XHTML 5 vs. XHTML5.

Your idea to use enumerate()
was correct.
indices = []
for i, elem in enumerate(mylist):
if 'aa' in elem:
indices.append(i)
Alternatively, as a list comprehension:
indices = [i for i, elem in enumerate(mylist) if 'aa' in elem]

The original question wants XYZ/ABC/(*files) to become ABC/ABC/(*files). After implementing the accepted answer for my own code, I noticed that it actually changes XYZ/ABC/(*files) into ABC/(*files). The filter-branch man page even says,
The result will contain that directory (and only that) as its project root."
In other words, it promotes the top-level folder "up" one level. That's an important distinction because, for example, in my history I had renamed a top-level folder. By promoting folders "up" one level, git loses continuity at the commit where I did the rename.
My answer to the question then is to make 2 copies of the repository and manually delete the folder(s) you want to keep in each. The man page backs me up with this:
[...] avoid using [this command] if a simple single commit would suffice to fix your problem
I blindly followed the accepted answer of using pip3 freeze > requirements.txt
It generated a huge file that listed all the dependencies of the entire solution, which is not what I wanted.
So you need to figure out what sort of requirements.txt you are trying to generate.
If you need a requirements.txt file that has ALL the dependencies, then use the pip3
pip3 freeze > requirements.txt
However, if you want to generate a minimal requirements.txt that only lists the dependencies you need, then use the pipreqs package. Especially helpful if you have numerous requirements.txt files in per component level in the project and not a single file on the solution wide level.
pip install pipreqs
pipreqs [path to folder]
e.g. pipreqs .
Are you moving it using svn mv

Try to disable SELinux by this command /usr/sbin/setenforce 0
. In my case it solved the problem.
Another approach is by using regular expressions.
$fileName = basename($filePath);
$fileNameNoExtension = preg_replace("/\.[^.]+$/", "", $fileName);
This removes from the last period .

$select.html('');
//iterate over the data and append a select option
$.each(data.List, function(key, val){

The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.
Then try the following:
@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST,
consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE,
produces = {MediaType.APPLICATION_ATOM_XML_VALUE, MediaType.APPLICATION_JSON_VALUE})
public @ResponseBody Representation authenticate(@PathVariable("email") String anEmailAddress, MultiValueMap paramMap) throws Exception {
if(paramMap == null && paramMap.get("password") == null) {
throw new IllegalArgumentException("Password not provided");
}
return null;
}
Note that removed the annotation @RequestBody

As already noted by gezzed in his comment, meanwhile there is a good solution (described in Polling must die: triggering Jenkins builds from a Git hook):
Set the Jenkins job's build trigger to Poll SCM, but do not specify a schedule.
Create a GitHub post-receive trigger to notify the URL
http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>?token=<get token from git to build remotely>
This will trigger all builds that poll the specified Git repository.
However, polling actually checks whether anything has been pushed to the used branch.
It works perfectly.
AFAIK JSON.Net does not provide functionality for reading from a URL. So you need to do this in two steps:
using (var webClient = new System.Net.WebClient()) {
var json = webClient.DownloadString(URL);
// Now parse with JSON.Net
}
To test and try curl requests from Windows, you can make use of Postman client Chrome extension. It is very simple to use and quite powerful.
Or as suggested you can install the cURL util.
A sample curl request is as follows.
curl -X POST -H "Content-Type: application/json" -H "Cache-Control: no-cache" -d '{
"user" : "Arun Thundyill Saseendran",
"post_date" : "2009-03-23T12:30:00",
"message" : "trying out Elasticsearch"
}' "http://10.103.102.56:9200/sampleindex/sampletype/"
I am also getting started with and exploring ES in vast. So please let me know if you have any other doubts.
EDIT: Updated the index name and type name to be fully lowercase to avoid errors and follow convention.

Note that the fs(yaffs2) and device(/dev/block/mtdblock3) are depend on your system.

Here is a real quick temporary fix, at least until you reboot again but it will get rid of a persistent access. I had installed a program that works fine but for some reason, there is a point that did not install correctly in the right file. So when it cannot access the file, it pops up the access denied but instead of just one, it keeps trying to start it up so even searching for the location to stop it permanently, it will continue to pop up more and more and more every 3 seconds. To stop that from happening at least temporarily, do the following...
That will prevent the window from persistently popping up, at least until you reboot. I know that does not solve the problem but like anything, there is a process of elimination and this step here will at least make it a little less annoying.
In my case, the file ~/.curlrc had a wrong proxy configured.
Declare separate functions in the <head> section and invoke those in your onClick method. If you have lots you could use a naming scheme that numbers them, or pass an integer in in your onClicks and have a big fat switch statement in the function.
for item in my_list:
if item.find("abc") != -1:
print item
You can use Lodash debounce https://lodash.com/docs/4.17.5#debounce method. It is simple and effective.
import * as lodash from lodash;
const update = (input) => {
// Update the input here.
console.log(`Input ${input}`);
}
const debounceHandleUpdate = lodash.debounce((input) => update(input), 200, {maxWait: 200});
doHandleChange() {
debounceHandleUpdate(input);
}
You can also cancel the debounce method by using the below method.
this.debounceHandleUpdate.cancel();
Hope it helps you. Cheers!!
All three give the same result if we modify the second one a bit:
my @arr = (2, 4, 8, 10);
print "First result:\n";
print scalar @arr;
print "\n\nSecond result:\n";
print $#arr + 1; # Shift numeration with +1 as it shows last index that starts with 0.
print "\n\nThird result:\n";
my $arrSize = @arr;
print $arrSize;
It's the array that's causing trouble in:
void print_graph(g_node graph_node[], double weight[][], int nodes);
The second and subsequent dimensions must be given:
void print_graph(g_node graph_node[], double weight[][32], int nodes);
Or you can just give a pointer to pointer:
void print_graph(g_node graph_node[], double **weight, int nodes);
However, although they look similar, those are very different internally.
If you're using C99, you can use variably-qualified arrays. Quoting an example from the C99 standard (section §6.7.5.2 Array Declarators):
void fvla(int m, int C[m][m]); // valid: VLA with prototype scope
void fvla(int m, int C[m][m]) // valid: adjusted to auto pointer to VLA
{
typedef int VLA[m][m]; // valid: block scope typedef VLA
struct tag {
int (*y)[n]; // invalid: y not ordinary identifier
int z[n]; // invalid: z not ordinary identifier
};
int D[m]; // valid: auto VLA
static int E[m]; // invalid: static block scope VLA
extern int F[m]; // invalid: F has linkage and is VLA
int (*s)[m]; // valid: auto pointer to VLA
extern int (*r)[m]; // invalid: r has linkage and points to VLA
static int (*q)[m] = &B; // valid: q is a static block pointer to VLA
}
[...] In my main(), the variable I am trying to pass into the function is a
double array[][]
, so how would I pass that into the function? Passingarray[0][0]
into it gives me incompatible argument type, as does&array
and&array[0][0]
.
In your main()
, the variable should be:
double array[10][20];
or something faintly similar; maybe
double array[][20] = { { 1.0, 0.0, ... }, ... };
You should be able to pass that with code like this:
typedef struct graph_node
{
int X;
int Y;
int active;
} g_node;
void print_graph(g_node graph_node[], double weight[][20], int nodes);
int main(void)
{
g_node g[10];
double array[10][20];
int n = 10;
print_graph(g, array, n);
return 0;
}
That compiles (to object code) cleanly with GCC 4.2 (i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)) and also with GCC 4.7.0 on Mac OS X 10.7.3 using the command line:
/usr/bin/gcc -O3 -g -std=c99 -Wall -Wextra -c zzz.c
The problem is that this character is UTF8, but json_encode does not handle it correctly. To say more, there is a list of other characters (see Unicode characters list), that will trigger the same error, so stripping off this one (Å) will not correct an issue to the end.
What we have used is to convert these chars to html entities like this:
htmlentities( (string) $value, ENT_QUOTES, 'utf-8', FALSE);
You can use extension method, recursion to resolve this problem:
public static bool DeepCompare(this object obj, object another)
{
if (ReferenceEquals(obj, another)) return true;
if ((obj == null) || (another == null)) return false;
//Compare two object's class, return false if they are difference
if (obj.GetType() != another.GetType()) return false;
var result = true;
//Get all properties of obj
//And compare each other
foreach (var property in obj.GetType().GetProperties())
{
var objValue = property.GetValue(obj);
var anotherValue = property.GetValue(another);
if (!objValue.Equals(anotherValue)) result = false;
}
return result;
}
public static bool CompareEx(this object obj, object another)
{
if (ReferenceEquals(obj, another)) return true;
if ((obj == null) || (another == null)) return false;
if (obj.GetType() != another.GetType()) return false;
//properties: int, double, DateTime, etc, not class
if (!obj.GetType().IsClass) return obj.Equals(another);
var result = true;
foreach (var property in obj.GetType().GetProperties())
{
var objValue = property.GetValue(obj);
var anotherValue = property.GetValue(another);
//Recursion
if (!objValue.DeepCompare(anotherValue)) result = false;
}
return result;
}
or compare by using Json (if object is very complex) You can use Newtonsoft.Json:
public static bool JsonCompare(this object obj, object another)
{
if (ReferenceEquals(obj, another)) return true;
if ((obj == null) || (another == null)) return false;
if (obj.GetType() != another.GetType()) return false;
var objJson = JsonConvert.SerializeObject(obj);
var anotherJson = JsonConvert.SerializeObject(another);
return objJson == anotherJson;
}
In Swift 3.0
func deleteAllRecords() {
//delete all data
let context = appDelegate.persistentContainer.viewContext
let deleteFetch = NSFetchRequest<NSFetchRequestResult>(entityName: "YourClassName")
let deleteRequest = NSBatchDeleteRequest(fetchRequest: deleteFetch)
do {
try context.execute(deleteRequest)
try context.save()
} catch {
print ("There was an error")
}
}
Look up the specification of HTTP. Or to get started, try http://www.jmarshall.com/easy/http/
Try this, it works for me:
var storage = null;
setLocalStorage();
function setLocalStorage() {
storage = (localStorage ? localStorage : (window.content.localStorage ? window.content.localStorage : null));
try {
storage.setItem('test_key', 'test_value');//verify if posible saving in the current storage
}
catch (e) {
if (e.name == "NS_ERROR_FILE_CORRUPTED") {
storage = sessionStorage ? sessionStorage : null;//set the new storage if fails
}
}
}

One option is to put the subquery in a LEFT JOIN
:
select sum ( t.graduates ) - t1.summedGraduates
from table as t
left join
(
select sum ( graduates ) summedGraduates, id
from table
where group_code not in ('total', 'others' )
group by id
) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates
Perhaps a better option would be to use SUM
with CASE
:
select sum(case when group_code = 'total' then graduates end) -
sum(case when group_code not in ('total','others') then graduates end)
from yourtable
The easiest way I've seen is to use Google Fonts.
Go to Google Fonts and choose a font, then Google will give you a link to put in your HTML.
Then add this to your custom.css:
h1, h2, h3, h4, h5, h6 {
font-family: 'Your Font' !important;
}
p, div {
font-family: 'Your Font' !important;
}
or
body {
font-family: 'Your Font' !important;
}
Use:
$("#id option").each(function()
{
// Add $(this).val() to your list
});
I think this should be a simple example:
$('#item1 span').text();
or
$('#item1 span').html();
Try browser.execute_script
instead of selenium.GetEval
.
See this answer for example.
I know I'm a little late to the party but in Kotlin you can easily use:
fun Collection<String>.containsIgnoreCase(item: String) = any {
it.equals(item, ignoreCase = true)
}
val list = listOf("Banana")
println(list.contains("banana"))
println(list.containsIgnoreCase("BaNaNa"))
The most simple way is to use Record type Record<number, productDetails >
interface productDetails {
productId : number ,
price : number ,
discount : number
};
const myVar : Record<number, productDetails> = {
1: {
productId : number ,
price : number ,
discount : number
}
}
Here is how I did it:
This was easier for me than trying to figure out the specific regex necessary.
int indexPictureData = result.IndexOf("-PictureData:");
int indexIdentity = result.IndexOf("-Identity:");
string returnValue = result.Remove(indexPictureData + 13);
returnValue = returnValue + " [bytecoderemoved] " + result.Remove(0, indexIdentity); `
