You can't read the transaction log file easily because that's not properly documented. There are basically two ways to do this. Using undocumented or semi-documented database functions or using third-party tools.
Note: This only makes sense if your database is in full recovery mode.
SQL Functions:
DBCC LOG and fn_dblog - more details here and here.
Third-party tools:
Toad for SQL Server and ApexSQL Log.
You can also check out several other topics where this was discussed:
In addition to the steps you have already taken, you will need to set the recovery mode to simple before you can shrink the log.
THIS IS NOT A RECOMMENDED PRACTICE for production systems... You will lose your ability to recover to a point in time from previous backups/log files.
See example B on this DBCC SHRINKFILE (Transact-SQL) msdn page for an example, and explanation.
Try this:
USE DatabaseName
GO
DBCC SHRINKFILE( TransactionLogName, 1)
BACKUP LOG DatabaseName WITH TRUNCATE_ONLY
DBCC SHRINKFILE( TransactionLogName, 1)
GO
new Date().toLocaleDateString();
simple as that, just pass your date to js Date Object
Yes you can use CASE
UPDATE table
SET columnB = CASE fieldA
WHEN columnA=1 THEN 'x'
WHEN columnA=2 THEN 'y'
ELSE 'z'
END
WHERE columnC = 1
It sounds like you have a form tag in a Master Page and in the Page that is throwing the error.
You can have only one.
With support for C++11 initializer lists it is very easy:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
using Strings = vector<string>;
void foo( Strings const& strings )
{
for( string const& s : strings ) { cout << s << endl; }
}
auto main() -> int
{
foo( Strings{ "hi", "there" } );
}
Lacking that (e.g. for Visual C++ 10.0) you can do things like this:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
typedef vector<string> Strings;
void foo( Strings const& strings )
{
for( auto it = begin( strings ); it != end( strings ); ++it )
{
cout << *it << endl;
}
}
template< class Elem >
vector<Elem>& r( vector<Elem>&& o ) { return o; }
template< class Elem, class Arg >
vector<Elem>& operator<<( vector<Elem>& v, Arg const& a )
{
v.push_back( a );
return v;
}
int main()
{
foo( r( Strings() ) << "hi" << "there" );
}
SELECT MAX(Salary) FROM Employee WHERE Salary NOT IN (SELECT MAX(Salary) FROM Employee )
This query will return the maximum salary, from the result - which not contains maximum salary from overall table.
First you should use print_r($_FILES)
to debug, and see what it contains. :
your uploads.php
would look like:
//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);
//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];
//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
//Tells you if its all ok
echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
// Connects to your Database
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;
//Writes the information to the database
mysql_query("INSERT INTO picture (Filename,Description)
VALUES ('$Filename', '$Description')") ;
} else {
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>
EDIT: Since this is old post, currently it is strongly recommended to use either mysqli or pdo instead mysql_ functions in php
In my case, I also got this error.
I already checked for other processes that might be the cause of locked database such as (SQLite Manager, other programs that connects to my database). But there's no other program that connects to it, it's just another active SQLConnection in the same application that stays connected.
Try checking your previous active SQLConnection that might be still connected (disconnect it first) before you establish a new SQLConnection and new command.
A column with default value:
CREATE TABLE <TableName>(
...
<ColumnName> <Type> DEFAULT <DefaultValue>
...
)
<DefaultValue>
is a placeholder for a:
(
expression )
Examples:
Count INTEGER DEFAULT 0,
LastSeen TEXT DEFAULT (datetime('now'))
Small update: Incase if you get below error in regard to node-sass follow the steps given below.
code EPERM
npm ERR! syscall unlink
steps to solve the issue:
I also struggled with HOME button for awhile. I wanted to stop/skip a background service (which polls location) when user clicks HOME button.
here is what I implemented as "hack-like" solution;
keep the state of the app on SharedPreferences using boolean value
on each activity
onResume() -> set appactive=true
onPause() -> set appactive=false
and the background service checks the appstate in each loop, skips the action
IF appactive=false
it works well for me, at least not draining the battery anymore, hope this helps....
I had the same problem, and found that the solution was to add the android:tools to the first node. In my case it is a LineraLayout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
This function should work whichever the locale and currency settings :
function getNumPrice(price, decimalpoint) {
var p = price.split(decimalpoint);
for (var i=0;i<p.length;i++) p[i] = p[i].replace(/\D/g,'');
return p.join('.');
}
This assumes you know the decimal point character (in my case the locale is set from PHP, so I get it with <?php echo cms_function_to_get_decimal_point(); ?>
).
Also, if you want to send embedded spaces with the input command, use %s
adb shell input text 'this%sis%san%sexample'
will yield
this is an example
being input.
%
itself does not need escaping - only the special %s
pair is treated specially. This leads of course to the obvious question of how to enter the literal string %s
, which you would have to do with two separate commands.
from your question I assume that you already have your data in hdfs.
So you don't need to LOAD DATA
, which moves the files to the default hive location /user/hive/warehouse
. You can simply define the table using the external
keyword, which leaves the files in place, but creates the table definition in the hive metastore. See here:
Create Table DDL
eg.:
create external table table_name (
id int,
myfields string
)
location '/my/location/in/hdfs';
Please note that the format you use might differ from the default (as mentioned by JigneshRawal in the comments). You can use your own delimiter, for example when using Sqoop:
row format delimited fields terminated by ','
<span>
will allow you to style text, but it adds no semantic content.
As you're emphasizing some text, it sounds like you'd be better served by wrapping the text in <em></em>
and using CSS to change the color of the <em>
element. For example:
.description {
color: #fff;
}
.description em {
color: #ffa500;
}
<p class="description">Lorem ipsum dolor sit amet, consectetur
adipiscing elit. Sed hendrerit mollis varius. Etiam ornare placerat
massa, <em>eget vulputate tellus fermentum.</em></p>
In fact, I'd go to great pains to avoid the <span>
element, as it's completely meaningless to everything that doesn't render your style sheet (bots, screen readers, luddites who disable styles, parsers, etc.) or renders it in unexpected ways (personal style sheets). In many ways, it's no better than using the <font>
element.
.description {_x000D_
color: #000;_x000D_
}_x000D_
_x000D_
.description em {_x000D_
color: #ffa500;_x000D_
}
_x000D_
<p class="description">Lorem ipsum dolor sit amet, consectetur _x000D_

Starting with .Net 4.5 you can use Task.Run to simply start an action:
void Foo(string args){}
...
Task.Run(() => Foo("bar"));
Based on @Micheal's answer, but checks for negative numbers and computes the square incrementally
public static bool IsPrime( int candidate ) {
if ( candidate % 2 <= 0 ) {
return candidate == 2;
}
int power2 = 9;
for ( int divisor = 3; power2 <= candidate; divisor += 2 ) {
if ( candidate % divisor == 0 )
return false;
power2 += divisor * 4 + 4;
}
return true;
}
Thank Alexander, I found a way how to modify format for en lang. (Didn't know which lang uses such format)
$.webshims.formcfg = {
en: {
dFormat: '/',
dateSigns: '/',
patterns: {
d: "yy/mm/dd"
}
}
};
$.webshims.activeLang('en');
It's a reserved keyword (like return, filter, function, break).
Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:
But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.
Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:
PS C:\> function ex{exit}
PS C:\> new-alias ^D ex
For non-printing characters, you can do the following:
One solution is with JQuery:
$(document).ready(
function () {
$('#mycheckboxId').click(function () {
// here the action or function to call
});
}
);
setTitle(getResources().getText(R.string.MyTitle));
this is the easy way to do that you just need to download the jar file "rs2xml.jar"
add it to your project
and do that :
1- creat a connection
2- statment and resultset
3- creat a jtable
4- give the result set to DbUtils.resultSetToTableModel(rs)
as define in this methode you well get your jtable so easy.
public void afficherAll(String tableName){
String sql="select * from "+tableName;
try {
stmt=con.createStatement();
rs=stmt.executeQuery(sql);
tbContTable.setModel(DbUtils.resultSetToTableModel(rs));
} catch (SQLException e) {
// TODO Auto-generated catch block
JOptionPane.showMessageDialog(null, e);
}
}
The number 61.0 does indeed have an exact floating-point operation—but that's not true for all integers. If you wrote a loop that added one to both a double-precision floating point number and a 64-bit integer, eventually you'd reach a point where the 64-bit integer perfectly represents a number, but the floating point doesn't—because there aren't enough significant bits.
It's just much easier to reach the point of approximation on the right side of the decimal point. If you started writing out all the numbers in binary floating point, it'd make more sense.
Another way of thinking about it is that when you note that 61.0 is perfectly representable in base 10, and shifting the decimal point around doesn't change that, you're performing multiplication by powers of ten (10^1, 10^-1). In floating point, multiplying by powers of two does not affect the precision of the number. Try taking 61.0 and dividing it by three repeatedly for an illustration of how a perfectly precise number can lose its precise representation.

I think You are trying to use the normal URL of video Like this :
Copying Direct URL from YouTube
That doesn't let you display the content on other domains.To Tackle this up , You should use the Copy Embed Code feature provided by the YouTube itself .Like this :
That would free you up from any issues .
For the above Scenario :
Go to Youtube Video

Stopping the Storyboard can be done in the code behind, or the xaml, depending on where the need comes from.
If the EventTrigger is moved outside of the button, then we can go ahead and target it with another EventTrigger that will tell the storyboard to stop. When the storyboard is stopped in this manner it will not revert to the previous value.
Here I've moved the Button.Click EventTrigger to a surrounding StackPanel and added a new EventTrigger on the the CheckBox.Click to stop the Button's storyboard when the CheckBox is clicked. This lets us check and uncheck the CheckBox when it is clicked on and gives us the desired unchecking behavior from the button as well.
<StackPanel x:Name="myStackPanel">
<CheckBox x:Name="myCheckBox"
Content="My CheckBox" />
<Button Content="Click to Uncheck"
x:Name="myUncheckButton" />
<Button Content="Click to check the box in code."
Click="OnClick" />
<StackPanel.Triggers>
<EventTrigger RoutedEvent="Button.Click"
SourceName="myUncheckButton">
<EventTrigger.Actions>
<BeginStoryboard x:Name="myBeginStoryboard">
<Storyboard x:Name="myStoryboard">
<BooleanAnimationUsingKeyFrames Storyboard.TargetName="myCheckBox"
Storyboard.TargetProperty="IsChecked">
<DiscreteBooleanKeyFrame KeyTime="00:00:00"
Value="False" />
</BooleanAnimationUsingKeyFrames>
</Storyboard>
</BeginStoryboard>
</EventTrigger.Actions>
</EventTrigger>
<EventTrigger RoutedEvent="CheckBox.Click"
SourceName="myCheckBox">
<EventTrigger.Actions>
<StopStoryboard BeginStoryboardName="myBeginStoryboard" />
</EventTrigger.Actions>
</EventTrigger>
</StackPanel.Triggers>
</StackPanel>
To stop the storyboard in the code behind, we will have to do something slightly different. The third button provides the method where we will stop the storyboard and set the IsChecked property back to true through code.
We can't call myStoryboard.Stop() because we did not begin the Storyboard through the code setting the isControllable parameter. Instead, we can remove the Storyboard. To do this we need the FrameworkElement that the storyboard exists on, in this case our StackPanel. Once the storyboard is removed, we can once again set the IsChecked property with it persisting to the UI.
private void OnClick(object sender, RoutedEventArgs e)
{
myStoryboard.Remove(myStackPanel);
myCheckBox.IsChecked = true;
}
(Mar 2017) The accepted answer is not the best solution. It relies on manual translation using Apps Script, and the code may not be resilient, requiring maintenance. If your legacy system autogenerates CSV files, it's best they go into another folder for temporary processing (importing [uploading to Google Drive & converting] to Google Sheets files).
My thought is to let the Drive API do all the heavy-lifting. The Google Drive API team released v3 at the end of 2015, and in that release, insert()
changed names to create()
so as to better reflect the file operation. There's also no more convert flag -- you just specify MIMEtypes... imagine that!
The documentation has also been improved: there's now a special guide devoted to uploads (simple, multipart, and resumable) that comes with sample code in Java, Python, PHP, C#/.NET, Ruby, JavaScript/Node.js, and iOS/Obj-C that imports CSV files into Google Sheets format as desired.
Below is one alternate Python solution for short files ("simple upload") where you don't need the apiclient.http.MediaFileUpload
class. This snippet assumes your auth code works where your service endpoint is DRIVE
with a minimum auth scope of https://www.googleapis.com/auth/drive.file
.
# filenames & MIMEtypes
DST_FILENAME = 'inventory'
SRC_FILENAME = DST_FILENAME + '.csv'
SHT_MIMETYPE = 'application/vnd.google-apps.spreadsheet'
CSV_MIMETYPE = 'text/csv'
# Import CSV file to Google Drive as a Google Sheets file
METADATA = {'name': DST_FILENAME, 'mimeType': SHT_MIMETYPE}
rsp = DRIVE.files().create(body=METADATA, media_body=SRC_FILENAME).execute()
if rsp:
print('Imported %r to %r (as %s)' % (SRC_FILENAME, DST_FILENAME, rsp['mimeType']))
Better yet, rather than uploading to My Drive
, you'd upload to one (or more) specific folder(s), meaning you'd add the parent folder ID(s) to METADATA
. (Also see the code sample on this page.) Finally, there's no native .gsheet "file" -- that file just has a link to the online Sheet, so what's above is what you want to do.
If not using Python, you can use the snippet above as pseudocode to port to your system language. Regardless, there's much less code to maintain because there's no CSV parsing. The only thing remaining is to blow away the CSV file temp folder your legacy system wrote to.
After trying most of the solutions here, the easiest thing I found was the obvious - using a temp file. I'm not sure what you want to do with your multiple line output, but you can then deal with it line by line using read. About the only thing you can't really do is easily stick it all in the same variable, but for most practical purposes this is way easier to deal with.
./myscript.sh > /tmp/foo
while read line ; do
echo 'whatever you want to do with $line'
done < /tmp/foo
Quick hack to make it do the requested action:
result=""
./myscript.sh > /tmp/foo
while read line ; do
result="$result$line\n"
done < /tmp/foo
echo -e $result
Note this adds an extra line. If you work on it you can code around it, I'm just too lazy.
EDIT: While this case works perfectly well, people reading this should be aware that you can easily squash your stdin inside the while loop, thus giving you a script that will run one line, clear stdin, and exit. Like ssh will do that I think? I just saw it recently, other code examples here: https://unix.stackexchange.com/questions/24260/reading-lines-from-a-file-with-bash-for-vs-while
One more time! This time with a different filehandle (stdin, stdout, stderr are 0-2, so we can use &3 or higher in bash).
result=""
./test>/tmp/foo
while read line <&3; do
result="$result$line\n"
done 3</tmp/foo
echo -e $result
you can also use mktemp, but this is just a quick code example. Usage for mktemp looks like:
filenamevar=`mktemp /tmp/tempXXXXXX`
./test > $filenamevar
Then use $filenamevar like you would the actual name of a file. Probably doesn't need to be explained here but someone complained in the comments.
Because JSON has a string data type (which is practically anything between "
and "
). It does not have a data type that matches something
You can emulate it like this:
countDownLatch = {
count: 0,
check: function() {
this.count--;
if (this.count == 0) this.calculate();
},
calculate: function() {...}
};
then each async call does this:
countDownLatch.count++;
while in each asynch call back at the end of the method you add this line:
countDownLatch.check();
In other words, you emulate a count-down-latch functionality.
For example, your remote host is example.com and remote login name is user1:
scp [email protected]:/path/to/file /path/to/store/file

I nearly used everything in that article to create the SQLite database for my own C# Application.
Don't forget to download the SQLite.dll, and add it as a reference to your project. This can be done using NuGet and by adding the dll manually.
After you added the reference, refer to the dll from your code using the following line on top of your class:
using System.Data.SQLite;
You can find the dll's here:
You can find the NuGet way here:
Up next is the create script. Creating a database file:
SQLiteConnection.CreateFile("MyDatabase.sqlite");
SQLiteConnection m_dbConnection = new SQLiteConnection("Data Source=MyDatabase.sqlite;Version=3;");
m_dbConnection.Open();
string sql = "create table highscores (name varchar(20), score int)";
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
sql = "insert into highscores (name, score) values ('Me', 9001)";
command = new SQLiteCommand(sql, m_dbConnection);
command.ExecuteNonQuery();
m_dbConnection.Close();
After you created a create script in C#, I think you might want to add rollback transactions, it is safer and it will keep your database from failing, because the data will be committed at the end in one big piece as an atomic operation to the database and not in little pieces, where it could fail at 5th of 10 queries for example.
Example on how to use transactions:
using (TransactionScope tran = new TransactionScope())
{
//Insert create script here.
//Indicates that creating the SQLiteDatabase went succesfully, so the database can be committed.
tran.Complete();
}

Other answers did a great job of explaining differences between interfaces and traits. I will focus on a useful real world example, in particular one which demonstrates that traits can use instance variables - allowing you add behavior to a class with minimal boilerplate code.
Again, like mentioned by others, traits pair well with interfaces, allowing the interface to specify the behavior contract, and the trait to fulfill the implementation.
Adding event publish / subscribe capabilities to a class can be a common scenario in some code bases. There's 3 common solutions:
use
the trait, aka import it, to gain the capabilities.How well does each work?
#1 Doesn't work well. It would, until the day you realize you can't extend the base class because you're already extending something else. I won't show an example of this because it should be obvious how limiting it is to use inheritance like this.
#2 & #3 both work well. I'll show an example which highlights some differences.
First, some code that will be the same between both examples:
An interface
interface Observable {
function addEventListener($eventName, callable $listener);
function removeEventListener($eventName, callable $listener);
function removeAllEventListeners($eventName);
}
And some code to demonstrate usage:
$auction = new Auction();
// Add a listener, so we know when we get a bid.
$auction->addEventListener('bid', function($bidderName, $bidAmount){
echo "Got a bid of $bidAmount from $bidderName\n";
});
// Mock some bids.
foreach (['Moe', 'Curly', 'Larry'] as $name) {
$auction->addBid($name, rand());
}
Ok, now lets show how the implementation of the Auction
class will differ when using traits.
First, here's how #2 (using composition) would look like:
class EventEmitter {
private $eventListenersByName = [];
function addEventListener($eventName, callable $listener) {
$this->eventListenersByName[$eventName][] = $listener;
}
function removeEventListener($eventName, callable $listener) {
$this->eventListenersByName[$eventName] = array_filter($this->eventListenersByName[$eventName], function($existingListener) use ($listener) {
return $existingListener === $listener;
});
}
function removeAllEventListeners($eventName) {
$this->eventListenersByName[$eventName] = [];
}
function triggerEvent($eventName, array $eventArgs) {
foreach ($this->eventListenersByName[$eventName] as $listener) {
call_user_func_array($listener, $eventArgs);
}
}
}
class Auction implements Observable {
private $eventEmitter;
public function __construct() {
$this->eventEmitter = new EventEmitter();
}
function addBid($bidderName, $bidAmount) {
$this->eventEmitter->triggerEvent('bid', [$bidderName, $bidAmount]);
}
function addEventListener($eventName, callable $listener) {
$this->eventEmitter->addEventListener($eventName, $listener);
}
function removeEventListener($eventName, callable $listener) {
$this->eventEmitter->removeEventListener($eventName, $listener);
}
function removeAllEventListeners($eventName) {
$this->eventEmitter->removeAllEventListeners($eventName);
}
}
Here's how #3 (traits) would look like:
trait EventEmitterTrait {
private $eventListenersByName = [];
function addEventListener($eventName, callable $listener) {
$this->eventListenersByName[$eventName][] = $listener;
}
function removeEventListener($eventName, callable $listener) {
$this->eventListenersByName[$eventName] = array_filter($this->eventListenersByName[$eventName], function($existingListener) use ($listener) {
return $existingListener === $listener;
});
}
function removeAllEventListeners($eventName) {
$this->eventListenersByName[$eventName] = [];
}
protected function triggerEvent($eventName, array $eventArgs) {
foreach ($this->eventListenersByName[$eventName] as $listener) {
call_user_func_array($listener, $eventArgs);
}
}
}
class Auction implements Observable {
use EventEmitterTrait;
function addBid($bidderName, $bidAmount) {
$this->triggerEvent('bid', [$bidderName, $bidAmount]);
}
}
Note that the code inside the EventEmitterTrait
is exactly the same as what's inside the EventEmitter
class except the trait declares the triggerEvent()
method as protected. So, the only difference you need to look at is the implementation of the Auction
class.
And the difference is large. When using composition, we get a great solution, allowing us to reuse our EventEmitter
by as many classes as we like. But, the main drawback is the we have a lot of boilerplate code that we need to write and maintain because for each method defined in the Observable
interface, we need to implement it and write boring boilerplate code that just forwards the arguments onto the corresponding method in our composed the EventEmitter
object. Using the trait in this example lets us avoid that, helping us reduce boilerplate code and improve maintainability.
However, there may be times where you don't want your Auction
class to implement the full Observable
interface - maybe you only want to expose 1 or 2 methods, or maybe even none at all so that you can define your own method signatures. In such a case, you might still prefer the composition method.
But, the trait is very compelling in most scenarios, especially if the interface has lots of methods, which causes you to write lots of boilerplate.
* You could actually kinda do both - define the EventEmitter
class in case you ever want to use it compositionally, and define the EventEmitterTrait
trait too, using the EventEmitter
class implementation inside the trait :)
It is possible of course, use -l:
instead of -l
. For example -l:libXYZ.a
to link with libXYZ.a
. Notice the lib
written out, as opposed to -lXYZ
which would auto expand to libXYZ
.
Sometimes you can use the CROSS APPLY operator like this:
select distinct result.* from data d
cross apply (select top 1 * from data where data.Id = d.Id) result
In this query I need to pick only the first of many duplicates that naturally happen to occur in my data. It works on SQL Server 2005+ databases.
Since vertical-align
works as expected on a td
, you could put a single celled table
in the div
to align its content.
<div>
<table style="width: 100%; height: 100%;"><tr><td style="vertical-align: middle; text-align: center">
Aligned content here...
</td></tr></table>
</div>
Clunky, but works as far as I can tell. It might not have the drawbacks of the other workarounds.
Try
if (!(i == 'InvKey' || i == 'PostDate')) {
or
if (i != 'InvKey' || i != 'PostDate') {
that says if i does not equals InvKey
OR PostDate
You can not ask for instance during configuration phase - you can ask only for providers.
var app = angular.module('modx', []);
// configure stuff
app.config(function($routeProvider, $locationProvider) {
// you can inject any provider here
});
// run blocks
app.run(function($rootScope) {
// you can inject any instance here
});
See http://docs.angularjs.org/guide/module for more info.
If you already have var parent = document.querySelector('.parent');
you can do this to scope the search to parent
's children:
parent.querySelector('.child')
That plugin will automatically do the "organize import" action on file save: https://github.com/dubreuia/intellij-plugin-save-actions.

<translate
android:duration="1500"
android:fromYDelta="100%"
android:toYDelta="1%" />
</set>
JAVA:
LinearLayout ll = findViewById(R.id.ll);
Animation animation;
animation = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.sample_animation);
ll .setAnimation(animation);
str.replace(/[[\]]/g,'')
All you need is parent
part if you use pathlib
.
from pathlib import Path
p = Path(r'C:\Program Files\Internet Explorer\iexplore.exe')
print(p.parent)
Will output:
C:\Program Files\Internet Explorer
Case you need all parts (already covered in other answers) use parts
:
p = Path(r'C:\Program Files\Internet Explorer\iexplore.exe')
print(p.parts)
Then you will get a list:
('C:\\', 'Program Files', 'Internet Explorer', 'iexplore.exe')
Saves tone of time.
This worked for me:
select pg_terminate_backend(pid) from pg_stat_activity where datname='YourDatabase';
for postgresql earlier than 9.2 replace pid
with procpid
DROP DATABASE "YourDatabase";
First create an object of class2 in class1 and then use that object to call any function of class2 for example write this in class1
class2 obj= new class2();
obj.thefunctioname(args);
You need to encode your parameter's values before concatenating them to URL.
Backslash \
is special character which have to be escaped as %5C
Escaping example:
String paramValue = "param\\with\\backslash";
String yourURLStr = "http://host.com?param=" + java.net.URLEncoder.encode(paramValue, "UTF-8");
java.net.URL url = new java.net.URL(yourURLStr);
The result is http://host.com?param=param%5Cwith%5Cbackslash
which is properly formatted url string.
Your task declaration is incorrectly combining the Copy
task type and project.copy
method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy
isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File
API) will do. Assuming Project1
is the project directory:
task renABCToXYZ { doLast { file("ABC").renameTo(file("XYZ")) } }
Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast
task action) to the task that produces ABC
.
Anyone going for Bootstrap 5 (beta as on date), here is what worked for me. In my case, I had to align two items in the card's header section side-by-side:
<div class="card small-card text-white bg-secondary">
<div class="d-flex justify-content-between card-header">
<div class="col-md-6 col-sm-6">
<h4>100+ Components</h4>
</div>
<div class="ml-auto">
<!--<div class="col-md-6 col-sm-6 ml-auto"> -->
<i class="data-feather hoverzoom" data-feather="grid"></i>
</div>
</div>
<div class="card-body">
<p>Lorem ipsum dolor sit amet, adipscing elitr, sed diam
nonumy eirmod tempor ividunt labor dolore magna.</p>
</div>
</div>
The catch here is justify-content-between
and ml-auto
. You can get more info here at the official link. And a live working example here.

Someone recommended Joda Time so - I have been using this CalendarDate class http://calendardate.sourceforge.net
It's a somewhat competing project to Joda Time, but much more basic at only 2 classes. It's very handy and worked great for what I needed since I didn't want to use a package bigger than my project. Unlike the Java counterparts, its smallest unit is the day so it is really a date (not having it down to milliseconds or something). Once you create the date, all you do to subtract is something like myDay.addDays(-5) to go back 5 days. You can use it to find the day of the week and things like that. Another example:
CalendarDate someDay = new CalendarDate(2011, 10, 27);
CalendarDate someLaterDay = today.addDays(77);
And:
//print 4 previous days of the week and today
String dayLabel = "";
CalendarDate today = new CalendarDate(TimeZone.getDefault());
CalendarDateFormat cdf = new CalendarDateFormat("EEE");//day of the week like "Mon"
CalendarDate currDay = today.addDays(-4);
while(!currDay.isAfter(today)) {
dayLabel = cdf.format(currDay);
if (currDay.equals(today))
dayLabel = "Today";//print "Today" instead of the weekday name
System.out.println(dayLabel);
currDay = currDay.addDays(1);//go to next day
}
Another method: insert the following in your theme's function.php file.
remove_filter('get_the_excerpt', 'wp_trim_excerpt');
add_filter('get_the_excerpt', 'custom_trim_excerpt');
function custom_trim_excerpt($text) { // Fakes an excerpt if needed
global $post;
if ( '' == $text ) {
$text = get_the_content('');
$text = apply_filters('the_content', $text);
$text = str_replace(']]>', ']]>', $text);
$text = strip_tags($text);
$excerpt_length = x;
$words = explode(' ', $text, $excerpt_length + 1);
if (count($words) > $excerpt_length) {
array_pop($words);
array_push($words, '...');
$text = implode(' ', $words);
}
}
return $text;
}
You can use this.
just type
cordova platform ls
This will list all the platforms installed along with its version and available for installation plus :)

Switch fallthrough is historically one of the major source of bugs in modern softwares. The language designer decided to make it mandatory to jump at the end of the case, unless you are defaulting to the next case directly without processing.
switch(value)

case 1:// this is still legal
case 2:
}
It depends on when the self executing anonymous function is running. It is possible that it is running before window.document
is defined.
In that case, try adding a listener
window.addEventListener('load', yourFunction, false);
// ..... or
window.addEventListener('DOMContentLoaded', yourFunction, false);
yourFunction () {
// some ocde
}
Update: (after the update of the question and inclusion of the code)
Read the following about the issues in referencing DOM elements from a JavaScript inserted and run in head

- “getElementsByTagName(…)[0]” is undefined?
- Traversing the DOM
In Windows, if you want to move the npm or nodejs folder in disk C to another location, but it still makes sure node and npm works well, you can create symlink like this: Open Command Prompt:
mklink /D "your_location_want_to_create_symlink" "location_of_node_npm_file"
Example:
mklink /D "C:\Users\MyUser\AppData\Roaming\npm" "D:\Nodejs Data\npm"
Now you've created a symlink for npm folder, this symlink will refer to D:\Nodejs Data\npm
Everything will work well.
Use Datatable.Default.Sort
property and then bind it to the datagridview.
I think it works the other way
<#if object.attribute??>
Do whatever you want....
</#if>
If object.attribute
is NOT NULL, then the content will be printed.
You can use it to transform some aggregate functions into analytic:
SELECT MAX(date)
FROM mytable
will return 1
row with a single maximum,
SELECT MAX(date) OVER (ORDER BY id)
FROM mytable
will return all rows with a running maximum.
Configuration
The styles and scripts options in your angular.json configuration now allow to reference a package directly:
before: "styles": ["../node_modules/bootstrap/dist/css/bootstrap.css"]
after: "styles": ["bootstrap/dist/css/bootstrap.css"]
"builder": "@angular-devkit/build-angular:browser",
"options": {
"outputPath": "dist/ng6",
"index": "src/index.html",
"main": "src/main.ts",
"polyfills": "src/polyfills.ts",
"tsConfig": "src/tsconfig.app.json",
"assets": [
"src/favicon.ico",

],
"styles": [
"src/styles.css","bootstrap/dist/css/bootstrap.min.css"
],
"scripts": [
"jquery/dist/jquery.min.js",
"bootstrap/dist/js/bootstrap.min.js"
]
},
Angular v6 Onwards
CLI projects in angular 6 onwards will be using angular.json
instead of .angular-cli.json
for build and project configuration.
Each CLI workspace has projects, each project has targets, and each target can have configurations.Docs
. {
"projects": {
"my-project-name": {
"projectType": "application",
"architect": {
"build": {
"configurations": {
"production": {},
"demo": {},
"staging": {},
}
},
"serve": {},
"extract-i18n": {},
"test": {},
}
},
"my-project-name-e2e": {}
},
}
OPTION-1
execute npm install bootstrap@4 jquery --save
The JavaScript parts of Bootstrap
are dependent on jQuery
. So you need the jQuery
JavaScript
library file too.
In your angular.json add the file paths to the styles and scripts array in under build
target
NOTE:
Before v6 the Angular CLI project configuration was stored in <PATH_TO_PROJECT>/.angular-cli.json.
As of v6 the location of the file changed to angular.json.
Since there is no longer a leading dot, the file is no longer hidden by default and is on the same level.
which also means that file paths in angular.json should not contain leading dots and slash
i.e you can provide an absolute path instead of a relative path
In .angular-cli.json
file Path was "../node_modules/"
In angular.json
it is "node_modules/"
"build": {
"builder": "@angular-devkit/build-angular:browser",
"options": {
"outputPath": "dist/ng6",

OPTION 3
Execute npm install bootstrap
In src/styles.css
add the following line:
@import "~bootstrap/dist/css/bootstrap.css";
OPTION-4
ng-bootstrap It contains a set of native Angular directives based on Bootstrap’s markup and CSS. As a result, it's not dependent on jQuery or Bootstrap’s JavaScript
npm install --save @ng-bootstrap/ng-bootstrap
After Installation import it in your root module and register it in @NgModule
imports` array
import {NgbModule} from '@ng-bootstrap/ng-bootstrap';
@NgModule({
declarations: [AppComponent, ...],
imports: [NgbModule.forRoot(), ...],
bootstrap: [AppComponent]
})
NOTE
ng-bootstrap
requires Bootstrap's 4 css to be added in your project. you need to Install it explicitly via:
npm install bootstrap@4 --save
In your angular.json add the file paths to the styles array in under build
target
"styles": [
"src/styles.css",
"node_modules/bootstrap/dist/css/bootstrap.min.css"
],
Use update
, stop
and receive
events, check it over here
The array declaration should be:
Car[] garage = new Car[100];
You can also just assign directly:
garage[1] = new Car("Blue");
As you use Joda Time, you should use DateTimeFormatter
:
final DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy-MMM-dd");
final LocalDate dt = dtf.parseLocalDate(yourinput);
If using Java 8 or later, then refer to hertzi's answer
Create an extension on UIImage:
/// UIImage Extensions
extension UIImage {
func maskWithColor(color: UIColor) -> UIImage {
var maskImage = self.CGImage
let width = self.size.width
let height = self.size.height
let bounds = CGRectMake(0, 0, width, height)
let colorSpace = CGColorSpaceCreateDeviceRGB()
let bitmapInfo = CGBitmapInfo(CGImageAlphaInfo.PremultipliedLast.rawValue)
let bitmapContext = CGBitmapContextCreate(nil, Int(width), Int(height), 8, 0, colorSpace, bitmapInfo)
CGContextClipToMask(bitmapContext, bounds, maskImage)
CGContextSetFillColorWithColor(bitmapContext, color.CGColor)
CGContextFillRect(bitmapContext, bounds)
let cImage = CGBitmapContextCreateImage(bitmapContext)
let coloredImage = UIImage(CGImage: cImage)
return coloredImage!
}
}
Then you can use it like that:
image.maskWithColor(UIColor.redColor())
A bit decent web application consists of a mix of design patterns. I'll mention only the most important ones.
The core (architectural) design pattern you'd like to use is the Model-View-Controller pattern. The Controller is to be represented by a Servlet which (in)directly creates/uses a specific Model and View based on the request. The Model is to be represented by Javabean classes. This is often further dividable in Business Model which contains the actions (behaviour) and Data Model which contains the data (information). The View is to be represented by JSP files which have direct access to the (Data) Model by EL (Expression Language).
Then, there are variations based on how actions and events are handled. The popular ones are:
Request (action) based MVC: this is the simplest to implement. The (Business) Model works directly with HttpServletRequest
and HttpServletResponse
objects. You have to gather, convert and validate the request parameters (mostly) yourself. The View can be represented by plain vanilla HTML/CSS/JS and it does not maintain state across requests. This is how among others Spring MVC, Struts and Stripes works.
Component based MVC: this is harder to implement. But you end up with a simpler model and view wherein all the "raw" Servlet API is abstracted completely away. You shouldn't have the need to gather, convert and validate the request parameters yourself. The Controller does this task and sets the gathered, converted and validated request parameters in the Model. All you need to do is to define action methods which works directly with the model properties. The View is represented by "components" in flavor of JSP taglibs or XML elements which in turn generates HTML/CSS/JS. The state of the View for the subsequent requests is maintained in the session. This is particularly helpful for server-side conversion, validation and value change events. This is how among others JSF, Wicket and Play! works.
As a side note, hobbying around with a homegrown MVC framework is a very nice learning exercise, and I do recommend it as long as you keep it for personal/private purposes. But once you go professional, then it's strongly recommended to pick an existing framework rather than reinventing your own. Learning an existing and well-developed framework takes in long term less time than developing and maintaining a robust framework yourself.
In the below detailed explanation I'll restrict myself to request based MVC since that's easier to implement.
First, the Controller part should implement the Front Controller pattern (which is a specialized kind of Mediator pattern). It should consist of only a single servlet which provides a centralized entry point of all requests. It should create the Model based on information available by the request, such as the pathinfo or servletpath, the method and/or specific parameters. The Business Model is called Action
in the below HttpServlet
example.
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
try {
Action action = ActionFactory.getAction(request);
String view = action.execute(request, response);
if (view.equals(request.getPathInfo().substring(1)) {
request.getRequestDispatcher("/WEB-INF/" + view + ".jsp").forward(request, response);
}
else {
response.sendRedirect(view); // We'd like to fire redirect in case of a view change as result of the action (PRG pattern).
}
}
catch (Exception e) {
throw new ServletException("Executing action failed.", e);
}
}
Executing the action should return some identifier to locate the view. Simplest would be to use it as filename of the JSP. Map this servlet on a specific url-pattern
in web.xml
, e.g. /pages/*
, *.do
or even just *.html
.
In case of prefix-patterns as for example /pages/*
you could then invoke URL's like http://example.com/pages/register, http://example.com/pages/login, etc and provide /WEB-INF/register.jsp
, /WEB-INF/login.jsp
with the appropriate GET and POST actions. The parts register
, login
, etc are then available by request.getPathInfo()
as in above example.
When you're using suffix-patterns like *.do
, *.html
, etc, then you could then invoke URL's like http://example.com/register.do, http://example.com/login.do, etc and you should change the code examples in this answer (also the ActionFactory
) to extract the register
and login
parts by request.getServletPath()
instead.
The Action
should follow the Strategy pattern. It needs to be defined as an abstract/interface type which should do the work based on the passed-in arguments of the abstract method (this is the difference with the Command pattern, wherein the abstract/interface type should do the work based on the arguments which are been passed-in during the creation of the implementation).
public interface Action {
public String execute(HttpServletRequest request, HttpServletResponse response) throws Exception;
}
You may want to make the Exception
more specific with a custom exception like ActionException
. It's just a basic kickoff example, the rest is all up to you.
Here's an example of a LoginAction
which (as its name says) logs in the user. The User
itself is in turn a Data Model. The View is aware of the presence of the User
.
public class LoginAction implements Action {
public String execute(HttpServletRequest request, HttpServletResponse response) throws Exception {
String username = request.getParameter("username");
String password = request.getParameter("password");
User user = userDAO.find(username, password);
if (user != null) {
request.getSession().setAttribute("user", user); // Login user.
return "home"; // Redirect to home page.
}
else {
request.setAttribute("error", "Unknown username/password. Please retry."); // Store error message in request scope.
return "login"; // Go back to redisplay login form with error.
}
}
}
The ActionFactory
should follow the Factory method pattern. Basically, it should provide a creational method which returns a concrete implementation of an abstract/interface type. In this case, it should return an implementation of the Action
interface based on the information provided by the request. For example, the method and pathinfo (the pathinfo is the part after the context and servlet path in the request URL, excluding the query string).
public static Action getAction(HttpServletRequest request) {
return actions.get(request.getMethod() + request.getPathInfo());
}
The actions
in turn should be some static/applicationwide Map<String, Action>
which holds all known actions. It's up to you how to fill this map. Hardcoding:
actions.put("POST/register", new RegisterAction());
actions.put("POST/login", new LoginAction());
actions.put("GET/logout", new LogoutAction());
// ...
Or configurable based on a properties/XML configuration file in the classpath: (pseudo)
for (Entry entry : configuration) {
actions.put(entry.getKey(), Class.forName(entry.getValue()).newInstance());
}
Or dynamically based on a scan in the classpath for classes implementing a certain interface and/or annotation: (pseudo)
for (ClassFile classFile : classpath) {
if (classFile.isInstanceOf(Action.class)) {
actions.put(classFile.getAnnotation("mapping"), classFile.newInstance());
}
}
Keep in mind to create a "do nothing" Action
for the case there's no mapping. Let it for example return directly the request.getPathInfo().substring(1)
then.
Those were the important patterns so far.
To get a step further, you could use the Facade pattern to create a Context
class which in turn wraps the request and response objects and offers several convenience methods delegating to the request and response objects and pass that as argument into the Action#execute()
method instead. This adds an extra abstract layer to hide the raw Servlet API away. You should then basically end up with zero import javax.servlet.*
declarations in every Action
implementation. In JSF terms, this is what the FacesContext
and ExternalContext
classes are doing. You can find a concrete example in this answer.
Then there's the State pattern for the case that you'd like to add an extra abstraction layer to split the tasks of gathering the request parameters, converting them, validating them, updating the model values and execute the actions. In JSF terms, this is what the LifeCycle
is doing.
Then there's the Composite pattern for the case that you'd like to create a component based view which can be attached with the model and whose behaviour depends on the state of the request based lifecycle. In JSF terms, this is what the UIComponent
represent.
This way you can evolve bit by bit towards a component based framework.
Use the replace
function in js:
var emailAdd = $(this).text().replace(/ /g,'');
That will remove all the spaces
If you want to remove the leading and trailing whitespace only, use the jQuery $.trim method :
var emailAdd = $.trim($(this).text());
You can also use Scanner :
Scanner s = new Scanner(MyString);
s.nextInt();

As an alternative to 'save & quit', you can use git-commit's function git-commit-commit
, by default bound to C-c C-c. It will save the file and close it. Afterwards, you still have to close emacs with C-x C-c, as mentioned before. I am currently trying to find out how to make emacs quit automatically.
I have my scripts organized in different folders for each package I pull in from bower, plus my own script for my app. Since you are going to list the order of these scripts somewhere, why not just list them in your gulp file? For new developers on your project, it's nice that all your script end-points are listed here. You can do this with gulp-add-src:
gulpfile.js
var gulp = require('gulp'),
less = require('gulp-less'),
minifyCSS = require('gulp-minify-css'),
uglify = require('gulp-uglify'),
concat = require('gulp-concat'),
addsrc = require('gulp-add-src'),
sourcemaps = require('gulp-sourcemaps');
// CSS & Less
gulp.task('css', function(){
gulp.src('less/all.less')
.pipe(sourcemaps.init())
.pipe(less())
.pipe(minifyCSS())
.pipe(sourcemaps.write('source-maps'))
.pipe(gulp.dest('public/css'));
});
// JS
gulp.task('js', function() {
gulp.src('resources/assets/bower/jquery/dist/jquery.js')
.pipe(addsrc.append('resources/assets/bower/bootstrap/dist/js/bootstrap.js'))
.pipe(addsrc.append('resources/assets/bower/blahblah/dist/js/blah.js'))
.pipe(addsrc.append('resources/assets/js/my-script.js'))
.pipe(sourcemaps.init())
.pipe(concat('all.js'))
.pipe(uglify())
.pipe(sourcemaps.write('source-maps'))
.pipe(gulp.dest('public/js'));
});
gulp.task('default',['css','js']);
Note: jQuery and Bootstrap added for demonstration purposes of order. Probably better to use CDNs for those since they are so widely used and browsers could have them cached from other sites already.
Other than writings conditionals depending on what $SHELL/$TERM is set to, no. What's wrong with using Perl? It's pretty ubiquitous (I can't think of a single UNIX variant that doesn't have it), and it'll spare you the trouble.

They're nearly identical but bash
has more features – sh
is (more or less) an older subset of bash
.
sh
often means the original Bourne shell
, which predates bash
(Bourne *again* shell
), and was created in 1977. But, in practice, it may be better to think of it as a highly-cross-compatible shell compliant with the POSIX standard from 1992.
Scripts that start with #!/bin/sh
or use the sh
shell usually do so for backwards compatibility. Any unix/linux OS will have an sh
shell. On Ubuntu sh
often invokes dash
and on MacOS it's a special POSIX version of bash
. These shells may be preferred for standard-compliant behavior, speed or backwards compatibility.
bash
is newer than the original sh
, adds more features, and seeks to be backwards compatible with sh
. In theory, sh
programs should run in bash
. bash
is available on nearly all linux/unix machines and usually used by default – with the notable exception of MacOS defaulting to zsh
as of Catalina (10.15). FreeBSD, by default, does not come with bash
installed.
In here:
if (ValidationUtils.isNullOrEmpty(lastName)) {
registrationErrors.add(ValidationErrors.LAST_NAME);
}
if (!ValidationUtils.isEmailValid(email)) {
registrationErrors.add(ValidationErrors.EMAIL);
}
you check for null or empty value on lastname, but in isEmailValid you don't check for empty value. Something like this should do
if (ValidationUtils.isNullOrEmpty(email) || !ValidationUtils.isEmailValid(email)) {
registrationErrors.add(ValidationErrors.EMAIL);
}
or better yet, fix your ValidationUtils.isEmailValid() to cope with null email values. It shouldn't crash, it should just return false.
SELECT col,
COUNT(dupe_col) AS dupe_cnt
FROM TABLE
GROUP BY col
HAVING COUNT(dupe_col) > 1

This is quite easy with jQuery using insertAfter()
or insertBefore()
:
<div class="left">content</div>
<div class="right">sidebar</div>
<script>
$('.right').insertBefore('left');
</script>
_x000D_
If you want to to set o condition for mobile devices you can make it like this:
<script>
var $iW = $(window).innerWidth();
if ($iW < 992){
$('.right').insertBefore('.left');
}else{
$('.right').insertAfter('.left');
}
</script>

In my case I just change the order migrations are executed manually so table users is created first.
In folder database/migrations/ your migration filename have this format: year_month_day_hhmmss_create_XXXX_table.php
Just rename create user file so creation date of your table priorities table is set later than user date (even one second later is enough)
mkdir -p `dirname /nosuchdirectory/hi.txt` && cp -r urls-resume /nosuchdirectory/hi.txt
The accepted answer has it spot on, but if you might want to specify which class label should be assigned to a specific color or label you could do the following. I did a little label gymnastics with the colorbar, but making the plot itself reduces to a nice one-liner. This works great for plotting the results from classifications done with sklearn. Each label matches a (x,y) coordinate.
import matplotlib
import matplotlib.pyplot as plt
import numpy as np
x = [4,8,12,16,1,4,9,16]
y = [1,4,9,16,4,8,12,3]
label = [0,1,2,3,0,1,2,3]
colors = ['red','green','blue','purple']
fig = plt.figure(figsize=(8,8))
plt.scatter(x, y, c=label, cmap=matplotlib.colors.ListedColormap(colors))
cb = plt.colorbar()
loc = np.arange(0,max(label),max(label)/float(len(colors)))
cb.set_ticks(loc)
cb.set_ticklabels(colors)
Using a slightly modified version of this answer, one can generalise the above for N colors as follows:
import numpy as np
import matplotlib as mpl
import matplotlib.pyplot as plt
N = 23 # Number of labels
# setup the plot
fig, ax = plt.subplots(1,1, figsize=(6,6))
# define the data
x = np.random.rand(1000)
y = np.random.rand(1000)
tag = np.random.randint(0,N,1000) # Tag each point with a corresponding label
# define the colormap
cmap = plt.cm.jet
# extract all colors from the .jet map
cmaplist = [cmap(i) for i in range(cmap.N)]
# create the new map
cmap = cmap.from_list('Custom cmap', cmaplist, cmap.N)
# define the bins and normalize
bounds = np.linspace(0,N,N+1)
norm = mpl.colors.BoundaryNorm(bounds, cmap.N)
# make the scatter
scat = ax.scatter(x,y,c=tag,s=np.random.randint(100,500,N),cmap=cmap, norm=norm)
# create the colorbar
cb = plt.colorbar(scat, spacing='proportional',ticks=bounds)
cb.set_label('Custom cbar')
ax.set_title('Discrete color mappings')
plt.show()
Which gives:
This way you don't have to use any magic numbers:
os.MkdirAll(newPath, os.ModePerm)
Also, rather than using + to create paths, you can use:
import "path/filepath"
path := filepath.Join(someRootPath, someSubPath)
The above uses the correct separators automatically on each platform for you.
Just found this, it works for me and I personally find it easier to read.
This will set the actual index just like gnarf's answer number 3 option.
// sets selected index of a select box the actual index of 0
$("select#elem").attr('selectedIndex', 0);
This didn't used to work but does now... see bug: http://dev.jquery.com/ticket/1474
As recommended in the comments use :
$("select#elem").prop('selectedIndex', 0);
You tagged the question with both sql-server and plsql so I will provide answers for both SQL Server and Oracle.
In SQL Server you can use FOR XML PATH
to concatenate multiple rows together:
select distinct t.[user],
STUFF((SELECT distinct ', ' + t1.department
from yourtable t1
where t.[user] = t1.[user]
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,2,'') department
from yourtable t;
See SQL Fiddle with Demo.
In Oracle 11g+ you can use LISTAGG
:
select "User",
listagg(department, ',') within group (order by "User") as departments
from yourtable
group by "User"
Prior to Oracle 11g, you could use the wm_concat
function:
select "User",
wm_concat(department) departments
from yourtable
group by "User"
As mentioned in other answers, all of the following will work for the standard string-based syntax.
WAITFOR DELAY '02:00' --Two hours
WAITFOR DELAY '00:02' --Two minutes
WAITFOR DELAY '00:00:02' --Two seconds
WAITFOR DELAY '00:00:00.200' --Two tenths of a seconds
There is also an alternative method of passing it a DATETIME
value. You might think I'm confusing this with WAITFOR TIME
, but it also works for WAITFOR DELAY
.
Considerations for passing DATETIME
:
'1900-01-01'
).DATETIME
than to properly format a VARCHAR
.How to wait for 2 seconds:
--Example 1
DECLARE @Delay1 DATETIME
SELECT @Delay1 = '1900-01-01 00:00:02.000'
WAITFOR DELAY @Delay1
--Example 2
DECLARE @Delay2 DATETIME
SELECT @Delay2 = dateadd(SECOND, 2, convert(DATETIME, 0))
WAITFOR DELAY @Delay2
A note on waiting for TIME
vs DELAY
:
Have you ever noticed that if you accidentally pass WAITFOR TIME
a date that already passed, even by just a second, it will never return? Check it out:
--Example 3
DECLARE @Time1 DATETIME
SELECT @Time1 = getdate()
WAITFOR DELAY '00:00:01'
WAITFOR TIME @Time1 --WILL HANG FOREVER
Unfortunately, WAITFOR DELAY
will do the same thing if you pass it a negative DATETIME
value (yes, that's a thing).
--Example 4
DECLARE @Delay3 DATETIME
SELECT @Delay3 = dateadd(SECOND, -1, convert(DATETIME, 0))
WAITFOR DELAY @Delay3 --WILL HANG FOREVER
However, I would still recommend using WAITFOR DELAY
over a static time because you can always confirm your delay is positive and it will stay that way for however long it takes your code to reach the WAITFOR
statement.
As per June 2020, I suppose this version (pip install -U opencv-contrib-python==3.4.2.16

You can do it with a dynamic query.

select @cadena = @cadena + 'exec spAPI ' + ltrim(id) + ';'
from sysobjects;
exec(@cadena);
You just need to override the method for back button. You can leave the method empty if you want so that nothing will happen when you press back button. Please have a look at the code below:
@Override
public void onBackPressed()
{
// Your Code Here. Leave empty if you want nothing to happen on back press.
}
That's simple, in Java
your_component.setRotation(15);
or
your_component.setRotation(295.18f);
in XML
<Button android:rotation="15" />
since python 3.5 you can use *
iterable unpacking operator:
user_list = [*your_iterator]
but the pythonic way to do it is:
user_list = list(your_iterator)
As the other have mentioned, the load event does not bubble. Instead you can manually trigger a load-like event with a custom event:
$('#item').on('namespace/onload', handleOnload).trigger('namespace/onload')
If your element is already listening to a change
event:
$('#item').on('change', handleChange).trigger('change')
I find this works well. Though, I stick to custom events to be more explicit and avoid side effects.
document.getElementById("something").innerHTML = "<img src=\"something\" onmouseover=\"change('ex1')\" />";
OR
document.getElementById("something").innerHTML = '<img src="something" onmouseover="change(\'ex1\')" />';
It should be working...

Some form of rounding is often unavoidable when dealing with floating point numbers. This is because numbers that you can express exactly in base 10 cannot always be expressed exactly in base 2 (which your computer uses).
For example:
>>> .1
0.10000000000000001
In this case, you're seeing .1 converted to a string using repr
:
>>> repr(.1)
'0.10000000000000001'
I believe python chops off the last few digits when you use str() in order to work around this problem, but it's a partial workaround that doesn't substitute for understanding what's going on.
>>> str(.1)
'0.1'
I'm not sure exactly what problems "rounding" is causing you. Perhaps you would do better with string formatting as a way to more precisely control your output?
e.g.
>>> '%.5f' % .1
'0.10000'
>>> '%.5f' % .12345678
'0.12346'
I was getting lots of these errors running "M-x rgrep" from Emacs on Windows with /Git/usr/bin in my PATH. Apparently in that case, M-x rgrep uses "NUL" (the Windows null device) rather than "/dev/null". I fixed the issue by adding this to .emacs:
;; Prevent issues with the Windows null device (NUL)
;; when using cygwin find with rgrep.
(defadvice grep-compute-defaults (around grep-compute-defaults-advice-null-device)
"Use cygwin's /dev/null as the null-device."
(let ((null-device "/dev/null"))
ad-do-it))
(ad-activate 'grep-compute-defaults)
What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.
E.g.
<iframe width="1024" height="768" src="http://www.bbc.com" style="-webkit-transform:scale(0.5);-moz-transform-scale(0.5);"></iframe>
What's dumpsys and what are its benefit
dumpsys is an android tool that runs on the device and dumps interesting information about the status of system services.
Obvious benefits:
What information can we retrieve from dumpsys shell command and how we can use it
If you run dumpsys you would see a ton of system information. But you can use only separate parts of this big dump.

dumpsys is ultimately flexible and useful tool!
If you want to use this tool do not forget to add permission into your android manifest automatically android.permission.DUMP
Try to test all commands to learn more about dumpsys. Happy dumping!
All the answers for the Run->Run menu option go with the "/K" switch of cmd, so the terminal stays open, or "-i" for python.exe so python forces interactive mode - both to preserve the output for you to observe.
Yet in cmd /k
you have to type exit
to close it, in the python -i
- quit()
. If that is too much typing for your liking (for me it sure is :), the Run command to use is
cmd /k C:\Python27\python.exe "$(FULL_CURRENT_PATH)" & pause & exit
C:\Python27\python.exe
- obviously the full path to your python install (or just python
if you want to go with the first executable in your user's path).
&
is unconditional execution of the next command in Windows - unconditional as it runs regardless of the RC of the previous command (&&
is "and" - run only if the previous completed successfully, ||
- is "or").
pause
- prints "Press any key to continue . . ." and waits for any key (that output can be suppressed if need).
exit
- well, types the exit for you :)
So at the end, cmd
runs python.exe
which executes the current file and keeps the window opened, pause
waits for you to press any key, and exit
finally close the window once you press that any key.
As root on CentOS 7:
systemctl start memcached
systemctl stop memcached
systemctl restart memcached
To tell the service to start at reboot (ex chkconfig):
systemctl enable memcached
To tell the service to not start at reboot:
systemctl disable memcached
ECMAScript 6 sets can permit faster computing of the elements of one array that aren't in the other:
const myArray = ['a', 'b', 'c', 'd', 'e', 'f', 'g'];
const toRemove = new Set(['b', 'c', 'g']);
const difference = myArray.filter( x => !toRemove.has(x) );
console.log(difference); // ["a", "d", "e", "f"]

Since the lookup complexity for the V8 engine browsers use these days is O(1), the time complexity of the whole algorithm is O(n).
Here's a situation where you HAVE to use property accessors. Imagine you have a GENERIC abstract class with lots of implementation goodness to inherit into 8 concrete subclasses:
public abstract class Foo<T extends Bar> {
T oneThing;
T anotherThing;
// getters and setters ommited for brevity
// Lots and lots of implementation regarding oneThing and anotherThing here
}
Now exactly how should you annotate this class? The answer is YOU CAN'T annotate it at all with either field or property access because you can't specify the target entity at this point. You HAVE to annotate the concrete implementations. But since the persisted properties are declared in this superclass, you MUST used property access in the subclasses.
Field access is not an option in an application with abstract generic super-classes.
You can just type in command line (console) on Linux, in the repository directory:
$ git status
and you will see some text, among which something similar to:
...
On branch master
...
which means you are currently on master
branch. If you are editing any file at that moment and it is located in the same local repository (local directory containing the files that are under Git version control management), you are editing file in this branch.
You can use isin
method:
In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})
In [2]: df
Out[2]:
A B
0 5 1
1 6 2
2 3 3
3 4 5
In [3]: df[df['A'].isin([3, 6])]
Out[3]:
A B
1 6 2
2 3 3
And to get the opposite use ~
:
In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
A B
0 5 1
3 4 5
I wrote this method to handle UTF8 arrays and JSON problems. It works fine with array (simple and multidimensional).
/**
* Encode array from latin1 to utf8 recursively
* @param $dat
* @return array|string
*/
public static function convert_from_latin1_to_utf8_recursively($dat)
{
if (is_string($dat)) {
return utf8_encode($dat);
} elseif (is_array($dat)) {
$ret = [];
foreach ($dat as $i => $d) $ret[ $i ] = self::convert_from_latin1_to_utf8_recursively($d);
return $ret;
} elseif (is_object($dat)) {
foreach ($dat as $i => $d) $dat->$i = self::convert_from_latin1_to_utf8_recursively($d);
return $dat;
} else {
return $dat;
}
}
// Sample use
// Just pass your array or string and the UTF8 encode will be fixed
$data = convert_from_latin1_to_utf8_recursively($data);
Another way, which I've been using for awhile in XCode3:
See steps 1-15 above.
The nice thing about this way is it will use the same environment to develop in that you would use to run in outside of XCode (as setup from your bash .profile).
It's also generic enough to let you develop/run any type of file, not just python.
First, set up a loading image in a div. Next, get the div element. Then, set a function that edits the css to make the visibility to "hidden". Now, in the <body>
, put the onload to the function name.
For custom color to TitleText
at NavigationBar
, here a simple and short code for Swift 3:
UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName : UIColor.white]
or
navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName :UIColor.white]
Each line of a batch file will get executed; but only after the previous line has completed. In your case, as soon as it hits the ftp line the ftp program will start and take over user input. When it is closed then the remaining lines will execute. Meaning the username/password are never sent to the FTP program and instead will be fed to the command prompt itself once the ftp program is closed.
Instead you need to pass everything you need on the ftp command line. Something like:
@echo off
echo user MyUserName> ftpcmd.dat
echo MyPassword>> ftpcmd.dat
echo bin>> ftpcmd.dat
echo put %1>> ftpcmd.dat
echo quit>> ftpcmd.dat
ftp -n -s:ftpcmd.dat SERVERNAME.COM
del ftpcmd.dat
Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.
$("legend").each(function() {
var SoftwareItem = $(this).text();
itemCost = GetItemCost(SoftwareItem);
$("input:checked").each(function() {
var Component = $(this).next("label").text();
itemCost += GetItemCost(Component);
});
$(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
});
You want the zip
function.
for (f,b) in zip(foo, bar):
print "f: ", f ,"; b: ", b
Anonymous FTP usage is covered by RFC 1635: How to Use Anonymous FTP:
What is Anonymous FTP?
Anonymous FTP is a means by which archive sites allow general access to their archives of information. These sites create a special account called "anonymous".
…
Traditionally, this special anonymous user account accepts any string as a password, although it is common to use either the password "guest" or one's electronic mail (e-mail) address. Some archive sites now explicitly ask for the user's e-mail address and will not allow login with the "guest" password. Providing an e-mail address is a courtesy that allows archive site operators to get some idea of who is using their services.
These are general recommendations, though. Each FTP server may have its own guidelines.
For sample use of the ftp
command on anonymous FTP access, see appendix A:

}
#region IWin32Window Members
System.IntPtr System.Windows.Forms.IWin32Window.Handle

And to actually use it:
var dlg = new FolderBrowserDialog();
System.Windows.Forms.DialogResult result = dlg.ShowDialog(this.GetIWin32Window());
Here's the results of MY homework. It doesn't ensure the input is in the right range and I probably should be using StringBuilder
(time I looked it up!) and isn't one single method. But if anyone is reading this far I'd appreciate both positive and negative feedback on it!

This is not specific to sqlite but you can just do
SELECT * FROM ... WHERE UPPER(name) = UPPER('someone')
If B
is a Boolean array, write
B = B*1
(A bit code golfy.)
I prefer the second way.
When you use the first way, if you decide to use a parallel stream to improve performance, you'll have no control over the order in which the elements will be added to the output list by forEach
.
When you use toList
, the Streams API will preserve the order even if you use a parallel stream.
There's another alternative for lazy people. You can set the layer.cornerRadius
key path for your view in the Interface Builder. For example, if your view has a width = height of 48, set layer.cornerRadius = 24
:
However, this only works if you have a static size of the view (width/height is fixed)
and it's not showing the circle in the interface builder.
When in doubt, read the documentation:
filename = "C:\Temp\vblist.txt"
Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)
Do Until f.AtEndOfStream
WScript.Echo f.ReadLine
Loop
f.Close
I found the following approach to be the most effective for sampling a DataFrame:
print(df[A:B]) ## 'A' and 'B' are the first and last records in range
For example, print(df[10:15])
will print rows 10 through 15 - inclusive - from your data set.
you should to delete your the Override onOptionsItemSelected and replate your onCreateOptionsMenu with this code
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_action_bar_finish_order_stop, menu);
menu.getItem(0).setOnMenuItemClickListener(new FinishOrderStopListener(this, getApplication(), selectedChild));

According to Wikipedia, (and many programming books) the definition of method/function overloading is the following:
In some programming languages, function overloading or method overloading is the ability to create multiple functions of the same name with different implementations. Calls to an overloaded function will run a specific implementation of that function appropriate to the context of the call, allowing one function call to perform different tasks depending on context.
In typescript we cannot have different implementations of the same function that are called according to the number and type of arguments. This is because when TS is compiled to JS, the functions in JS have the following characteristics:
Therefore, in a strict sense, one could argue that TS function overloading doesn't exists. However, there are things you can do within your TS code that can perfectly mimick function overloading.
Here is an example:
function add(a: number, b: number, c: number): number;
function add(a: number, b: number): any;
function add(a: string, b: string): any;
function add(a: any, b: any, c?: any): any {
if (c) {
return a + c;
}
if (typeof a === 'string') {
return `a is ${a}, b is ${b}`;
} else {
return a + b;
}
}
The TS docs call this method overloading, and what we basically did is supplying multiple method signatures (descriptions of possible parameters and types) to the TS compiler. Now TS can figure out if we called our function correctly during compile time and give us an error if we called the function incorrectly.
Try this:
foreach (var dept in employees.SelectMany(e => e.Departments))
{
dept.SomeProperty = null;
collection.Add(dept);
}
In general, I would recommend that you look into using Python's struct module for this. It's standard with Python, and it should be easy to translate your question's specification into a formatting string suitable for struct.unpack()
.
Do note that if there's "invisible" padding between/around the fields, you will need to figure that out and include it in the unpack()
call, or you will read the wrong bits.
Reading the contents of the file in order to have something to unpack is pretty trivial:
import struct
data = open("from_fortran.bin", "rb").read()
(eight, N) = struct.unpack("@II", data)
This unpacks the first two fields, assuming they start at the very beginning of the file (no padding or extraneous data), and also assuming native byte-order (the @
symbol). The I
s in the formatting string mean "unsigned integer, 32 bits".
While so many answers mention this in some form by saying that regex does not support recursive matching and so on, the primary reason for this lies in the roots of the Theory of Computation.
Language of the form {a^nb^n | n>=0} is not regular
. Regex can only match things that form part of the regular set of languages.

If you are trying to set default value as NOW(),MySQL supports that you have to change the type of that column TIMESTAMP instead of DATETIME. TIMESTAMP have current date and time as default..i think it will resolved your problem..
I'd seriously recommend installing MacVim via MacPorts (sudo port install MacVim
).
When installed, MacPorts automatically updates your profile to include /opt/local/bin in your path, and so when mvim is installed as /opt/local/bin/mvim during the install of MacVim you'll find it ready to use straight away.
When you install the MacVim port the MacVim.app bundle is installed in /Applications/MacPorts for you too.
A good thing about going the MacPorts route is that you'll also be able to install git too (sudo port install git-core
) and many many other ports. Highly recommended.
Are you meaning?
data2 <- data1[good,]
With
data1[good]
you're selecting columns in a wrong way (using a logical vector of complete rows).
Consider that parameter pollutant
is not used; is it a column name that you want to extract? if so it should be something like
data2 <- data1[good, pollutant]
Furthermore consider that you have to rbind
the data.frame
s inside the for
loop, otherwise you get only the last data.frame (its completed.cases)
And last but not least, i'd prefer generating filenames eg with
id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")
A little modified chunk of ?sprintf
The string fmt
(in our case "%3d"
) contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through ...
. The allowed conversion specifications start with a %
and end with one of the letters in the set aAdifeEgGosxX%
. These letters denote the following types:
d
: integerEg a more general example
sprintf("I am %10d years old", 25)
[1] "I am 25 years old"

Heh tried all these answers and none of them worked. I think a common cause of this issue is something a lot simpler.
I advise all who get this problem to look at their launch configuration:
Look! The launch configuration contains options for which APK to deploy. If you choose default, Android Studio will be dumb to any product flavors, build types etc. you have in your gradle file. In my case, I have multiple build types and product flavors, and received "no local path" when trying to launch a non-default product flavor.
Android Studio was not wrong! It couldn't find the default APK, because I was not building for it. I solve my issue by instead choosing "Do not deploy anything" and then executing the gradle install task I needed for my specific combination of product flavor / build type.
It's almost correct.
Since the -
is a javascript operator, you can't really have that in property names. If you were setting, border
or something single-worded like that instead, your code would work just fine.
However, the thing you need to remember for padding-top
, and for any hyphenated attribute name, is that in javascript, you remove the hyphen, and make the next letter uppercase, so in your case that'd be paddingTop
.
There are some other exceptions. JavaScript has some reserved words, so you can't set float
like that, for instance. Instead, in some browsers you need to use cssFloat
and in others styleFloat
. It is for discrepancies like this that it is recommended that you use a framework such as jQuery, that handles browser incompatibilities for you...
PL/SQL is complaining that TRUE is not a valid identifier, or variable. Set up a local variable, set it to TRUE, and pass it into the get_something function.
Here is another python code to check whether closed segments intersect. It is the rewritten version of the C++ code in http://www.cdn.geeksforgeeks.org/check-if-two-given-line-segments-intersect/. This implementation covers all special cases (e.g. all points colinear).

(q[0] - p[0]) * (r[1] - q[1]))
if val == 0:
return 0 # colinear
elif val > 0:
return 1 # clockwise
else:
return 2 # counter-clockwise

You need to use array_merge_recursive
instead of array_merge
. Of course there can only be one key equal to 'c'
in the array, but the associated value will be an array containing both 3
and 4

You have to overrride the scale, try this: (applies to ChartJS v1.x)
window.onload = function(){
var ctx = document.getElementById("canvas").getContext("2d");
window.myLine = new Chart(ctx).Line(lineChartData, {
scaleOverride : true,
scaleSteps : 10,
scaleStepWidth : 50,
scaleStartValue : 0
});
}

ul li:not(:last-child){
border-right: 1px solid rgba(153, 151, 151, 0.75);

I had to handle this a while back. I removed the Tab from the TabPages collection (I think that's it) and added it back in when the conditions changed. But that was only in Winforms where I could keep the tab around until I needed it again.
WorksheetFunction Transpose()
Instead of copying, pasting via PasteSpecial, and using the Transpose
option you can simply type a formula
=TRANSPOSE(Sheet1!A1:A5)
or if you prefer VBA:
Dim v
v = WorksheetFunction.Transpose(Sheet1.Range("A1:A5"))
Sheet2.Range("A1").Resize(1, UBound(v)) = v
Note: alternatively you could use late-bound Application.Transpose
instead.
MS help reference states that having a current version of Microsoft 365, one can simply input the formula in the top-left-cell of the target range, otherwise the formula must be entered as a legacy array formula via Ctrl+Shift+Enter to confirm it.

Short answer: Use the change
event. Here's a couple of practical examples. Since I misread the question, I'll include jQuery examples along with plain JavaScript. You're not gaining much, if anything, by using jQuery though.
Using querySelector
.
var checkbox = document.querySelector("input[name=checkbox]");
checkbox.addEventListener('change', function() {
if (this.checked) {
console.log("Checkbox is checked..");
} else {
console.log("Checkbox is not checked..");
}
});
_x000D_
<input type="checkbox" name="checkbox" />
_x000D_
$('input[name=checkbox]').change(function() {
if ($(this).is(':checked')) {
console.log("Checkbox is checked..")
} else {
console.log("Checkbox is not checked..")
}
});
_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" name="checkbox" />
_x000D_
Here's an example of a list of checkboxes. To select multiple elements we use querySelectorAll
instead of querySelector
. Then use Array.filter
and Array.map
to extract checked values.
// Select all checkboxes with the name 'settings' using querySelectorAll.
var checkboxes = document.querySelectorAll("input[type=checkbox][name=settings]");
let enabledSettings = []
/*
For IE11 support, replace arrow functions with normal functions and
use a polyfill for Array.forEach:
https://vanillajstoolkit.com/polyfills/arrayforeach/
*/
// Use Array.forEach to add an event listener to each checkbox.
checkboxes.forEach(function(checkbox) {
checkbox.addEventListener('change', function() {
enabledSettings =
Array.from(checkboxes) // Convert checkboxes to an array to use filter and map.
.filter(i => i.checked) // Use Array.filter to remove unchecked checkboxes.
.map(i => i.value) // Use Array.map to extract only the checkbox values from the array of objects.
console.log(enabledSettings)
})
});
_x000D_
<label>
<input type="checkbox" name="settings" value="forcefield">

_x000D_
let checkboxes = $("input[type=checkbox][name=settings]")
let enabledSettings = [];
// Attach a change event handler to the checkboxes.
checkboxes.change(function() {
enabledSettings = checkboxes
.filter(":checked") // Filter out unchecked boxes.
.map(function() { // Extract values using jQuery map.
return this.value;
})
.get() // Get array.
console.log(enabledSettings);
});

Mutable objects have fields that can be changed, immutable objects have no fields that can be changed after the object is created.
A very simple immutable object is a object without any field. (For example a simple Comparator Implementation).
class Mutable{
private int value;
public Mutable(int value) {
this.value = value;
}
//getter and setter for value
}
class Immutable {
private final int value;
public Immutable(int value) {
this.value = value;
}
//only getter
}
static means that the variable or method marked as such is available at the class level. In other words, you don't need to create an instance of the class to access it.
public class Foo {
public static void doStuff(){
// does stuff
}
}
So, instead of creating an instance of Foo and then calling doStuff
like this:
Foo f = new Foo();
f.doStuff();
You just call the method directly against the class, like so:
Foo.doStuff();
print_r(unpack("H*","The quick fox jumped over the lazy brown dog"))
Array ( [1] => 54686520717569636b20666f78206a756d706564206f76657220746865206c617a792062726f776e20646f67 )
T = 0x54, h = 0x68, ...
You can split the result into two-hex-character chunks if necessary.
Here's a flow chart that illustrates a for loop:
The equivalent C code would be
for(i = 2; i <= 6; i = i + 2) {
printf("%d\t", i + 1);
}
I found this and several other examples on one of Tenouk's C Laboratory practice worksheets.
In the interest of coverage. I put forward an implementation using lambda expressions.
C++11
#include <vector>
#include <algorithm>
using namespace std;
vector< MyStruct > values;
sort( values.begin( ), values.end( ), [ ]( const MyStruct& lhs, const MyStruct& rhs )
{
return lhs.key < rhs.key;
});
C++14
#include <vector>
#include <algorithm>
using namespace std;
vector< MyStruct > values;
sort( values.begin( ), values.end( ), [ ]( const auto& lhs, const auto& rhs )
{
return lhs.key < rhs.key;
});
Add the following text to your xml file.
<!--Dummy layout that gain focus -->
<LinearLayout
android:layout_width="0dp"
android:layout_height="0dp"
android:focusable="true"
android:focusableInTouchMode="true"
android:orientation="vertical" >
</LinearLayout>
The illegal character is not in $matches[1]
, but in $xml
Try
iconv($matches[1], 'utf-8//TRANSLIT', $xml);
And showing us the input string would be nice for a better answer.
I suppose this depends on your architecture and whatever else you may need to consider, but you could also take the object-oriented approach and use a class.
class ClassName {
private $site_url;
function __construct( $url ) {
$this->site_url = $url;
}
public function parts( string $part ) {
echo 'http://' . $this->site_url . 'content/' . $part . '.php';
}
# You could build a bunch of other things here
# too and still have access to $this->site_url.
}
Then you can create and use the object wherever you'd like.
$obj = new ClassName($site_url);
$obj->parts('part_argument');
This could be overkill for what OP was specifically trying to achieve, but it's at least an option I wanted to put on the table for newcomers since nobody mentioned it yet.
The advantage here is scalability and containment. For example, if you find yourself needing to pass the same variables as references to multiple functions for the sake of a common task, that could be an indicator that a class is in order.

If you use <mvc:annotation-driven/>

If you do not want to depend on throwing exception (which you probably should not) you can try this:
public static <T> T cast(Object o, Class<T> clazz) {
return clazz.isInstance(o) ? clazz.cast(o) : null;
}
Both Google and Python's style guide is the best practice:
if x is not None:
# Do something about x
Using not x
can cause unwanted results.
See below:
>>> x = 1
>>> not x
False
>>> x = [1]
>>> not x
False
>>> x = 0
>>> not x
True
>>> x = [0] # You don't want to fall in this one.
>>> not x
False
You may be interested to see what literals are evaluated to True
or False
in Python:
Edit for comment below:
I just did some more testing. not x is None
doesn't negate x
first and then compared to None
. In fact, it seems the is
operator has a higher precedence when used that way:
>>> x
[0]
>>> not x is None
True
>>> not (x is None)
True
>>> (not x) is None
False
Therefore, not x is None
is just, in my honest opinion, best avoided.
More edit:
I just did more testing and can confirm that bukzor's comment is correct. (At least, I wasn't able to prove it otherwise.)
This means if x is not None
has the exact result as if not x is None
. I stand corrected. Thanks bukzor.
However, my answer still stands: Use the conventional if x is not None
. :]
The meaning of this exception is explained here: https://bz.apache.org/bugzilla/show_bug.cgi?id=27829
Summary: Java dies, Tomcat shut down hook is called, exception is thrown.
So if a firewall prevents the shutdown message from reaching Tomcat, Java will eventually die first (ex during system reboot/shutdown), and the exception will appear.
There are other possibilities.
In my case, my problem had something to do with my initscript (Linux) being incorrectly installed. That implied Java was getting killed by the OS during shutdown/reboot and not as a result of the script. The solution as simple as this:
chkconfig --del initscript
chkconfig --add initscript
Before the fix I had the following in rc.d:
find /etc/rc.d | grep initscript | sort
/etc/rc.d/init.d/initscript
/etc/rc.d/rc2.d/S85initscript
/etc/rc.d/rc3.d/S85initscript
/etc/rc.d/rc4.d/S85initscript
/etc/rc.d/rc5.d/S85initscript
After the fix:
find /etc/rc.d | grep initscript | sort
/etc/rc.d/init.d/initscript
/etc/rc.d/rc0.d/K15initscript
/etc/rc.d/rc1.d/K15initscript
/etc/rc.d/rc2.d/K15initscript
/etc/rc.d/rc3.d/K15initscript
/etc/rc.d/rc4.d/K15initscript
/etc/rc.d/rc5.d/S85initscript
/etc/rc.d/rc6.d/K15initscript
Conclusion: if you get this exception, make sure Tomcat is shutdown properly, not as a result of Java being terminated. Check your firewall, shutdown scripts etc.
The reason that max
works with apply
is that apply
is coercing your data frame to a matrix first, and a matrix can only hold one data type. So you end up with a matrix of characters. sapply
is just a wrapper for lapply
, so it is not surprising that both yield the same error.
The default behavior when you create a data frame is for categorical columns to be stored as factors. Unless you specify that it is an ordered factor, operations like max
and min
will be undefined, since R is assuming that you've created an unordered factor.
You can change this behavior by specifying options(stringsAsFactors = FALSE)
, which will change the default for the entire session, or you can pass stringsAsFactors = FALSE
in the data.frame()
construction call itself. Note that this just means that min
and max
will assume "alphabetical" ordering by default.
Or you can manually specify an ordering for each factor, although I doubt that's what you want to do.
Regardless, sapply
will generally yield an atomic vector, which will entail converting everything to characters in many cases. One way around this is as follows:
#Some test data
d <- data.frame(v1 = runif(10), v2 = letters[1:10],
v3 = rnorm(10), v4 = LETTERS[1:10],stringsAsFactors = TRUE)
d[4,] <- NA
#Similar function to DWin's answer
fun <- function(x){
if(is.numeric(x)){max(x,na.rm = 1)}
else{max(as.character(x),na.rm=1)}
}
#Use colwise from plyr package
colwise(fun)(d)
v1 v2 v3 v4
1 0.8478983 j 1.999435 J
All java objects are pointer because a variable which holds address is called pointer and object hold address.so object is pointer variable.
Apart from cool solutions above I'd mention also about supervisord and monit tools which allow to start process, monitor its presence and start it if it died. With 'monit' you can also run some active checks like check if process responds for http request
RichTextBox rtf = new RichTextBox();
System.IO.MemoryStream stream = new System.IO.MemoryStream(ASCIIEncoding.Default.GetBytes(yourText));
rtf.Selection.Load(stream, DataFormats.Rtf);
OR
rtf.Selection.Text = yourText;
Your code is correct you just used .div
instead of div

We've just come across a very similar issue and I'm now very much a +1 for never using Money except in top level presentation. We have multiple tables (effectively a sales voucher and sales invoice) each of which contains one or more Money fields for historical reasons, and we need to perform a pro-rata calculation to work out how much of the total invoice Tax is relevant to each line on the sales voucher. Our calculation is
vat proportion = total invoice vat x (voucher line value / total invoice value)
This results in a real world money / money calculation which causes scale errors on the division part, which then multiplies up into an incorrect vat proportion. When these values are subsequently added, we end up with a sum of the vat proportions which do not add up to the total invoice value. Had either of the values in the brackets been a decimal (I'm about to cast one of them as such) the vat proportion would be correct.
When the brackets weren't there originally this used to work, I guess because of the larger values involved, it was effectively simulating a higher scale. We added the brackets because it was doing the multiplication first, which was in some rare cases blowing the precision available for the calculation, but this has now caused this much more common error.
Sometimes you need to apply a function to the members of a list in place. The following code worked for me:
>>> def func(a, i):
... a[i] = a[i].lower()
>>> a = ['TEST', 'TEXT']
>>> list(map(lambda i:func(a, i), range(0, len(a))))
[None, None]
>>> print(a)
['test', 'text']
Please note, the output of map() is passed to the list constructor to ensure the list is converted in Python 3. The returned list filled with None values should be ignored, since our purpose was to convert list a in place
If you used the auth scaffolding in 5.5 simply direct your href
to:
{{ route('logout') }}
There is no need to alter any routes or controllers.
I would do it that way in python 2.
inv_map = {my_map[x] : x for x in my_map}
You say in a comment you want to get "15.09.2016".
For this, use Date
and DateFormatter
:
let date = Date()
let formatter = DateFormatter()
Give the format you want to the formatter:
formatter.dateFormat = "dd.MM.yyyy"
Get the result string:
let result = formatter.string(from: date)
Set your label:
label.text = result
Result:
15.09.2016
The most concise solution if you need the dates to be in Date format:
library(zoo)
month <- "2000-03"
as.Date(as.yearmon(month))
[1] "2000-03-01"
as.Date
will fix the first day of each month to a yearmon object for you.
I downloaded the jar file manually and replace the one in my local directory and it worked
If you have url with path variables, example www.myexampl.com/item/12/update where 12 is the id and create is the variable you want to use for specifying your execution for instance in using a single form to do an update and create, you do this in your controller.
@PostMapping(value = "/item/{id}/{method}")
public String getForm(@PathVariable("id") String itemId ,
@PathVariable("method") String methodCall , Model model){
if(methodCall.equals("create")){
//logic
}
if(methodCall.equals("update")){
//logic
}
return "path to your form";
}
All the other responses I see are fine, but C# has support for named groups!
I'd use the following code:
const string input = "Lorem ipsum dolor sit %download%#456 amet, consectetur adipiscing %download%#3434 elit. Duis non nunc nec mauris feugiat porttitor. Sed tincidunt blandit dui a viverra%download%#298. Aenean dapibus nisl %download%#893434 id nibh auctor vel tempor velit blandit.";
static void Main(string[] args)
{
Regex expression = new Regex(@"%download%#(?<Identifier>[0-9]*)");
var results = expression.Matches(input);
foreach (Match match in results)
{
Console.WriteLine(match.Groups["Identifier"].Value);
}
}
The code that reads: (?<Identifier>[0-9]*)
specifies that [0-9]*
's results will be part of a named group that we index as above: match.Groups["Identifier"].Value
As per this gist, the solution is to create a ~/.bash_profile
(in HOME
directory) that contains:
export SHELLOPTS
set -o igncr
BOOST_VERSION is defined in the boost header file version.hpp.
install the dependencies:
npm install jquery --save
npm install tether --save
npm install bootstrap@version --save;
next, add scripts in your angular-cli.json
"scripts": [
"../node_modules/jquery/dist/jquery.min.js",
"../node_modules/tether/dist/js/tether.js",
"../node_modules/bootstrap/dist/js/bootstrap.min.js",
"script.js"
]
then, create a script.js
$("[data-toggle=tooltip]").tooltip();
now restart your server.
In my case neither Windows Features nor aspnet_regiis -i

We offer a tool called DocFlex/XML XSDDoc that allows you to enjoy both things at once:
The diagrams in fact are generated not by us, but by Altova XMLSpy. We implemented an Integration with XMLSpy (with the full support of all diagram hyperlinks):
Here you can see the full this doc: http://www.filigris.com/docflex-xml/xsddoc/examples/html/XMLSchema/index.html
The whole thing provides a functionality not offered by any single vendor right now on the market!
Some our customers were so impressed that they purchased an extra license for XMLSpy only because of our tool. (That's no joke!)
Currently, we've also implemented similar integrations with other XML editors:
See: http://www.filigris.com/docflex-xml/OxygenXML/demo/html/xslt20/index.html
See: http://www.filigris.com/docflex-xml/LiquidXML/demo/html/XMLSchema/index.html
Concerning what all those diagrams depict... Essentially, they are all about content model of XSD elements (as well as other XSD components that lead to elements: complexTypes, element/attribute groups). It seems, there are two approaches here:
I personally believe that the diagrams generated by XMLSpy are more useful.
Yet, there were no attempts so far (at least known to me) to depict graphically anything else contained in XML schemas, although one can imagine many...
The chances are that the problem is in one of the unit tests that you've asked Maven to run.
As such, fiddling with the heap size is the wrong approach. Instead, you should be looking at the unit test that has caused the OOME, and trying to figure out if it is the fault of the unit test or the code that it is testing.
Start by looking at the stack trace. If there isn't one, run mvn ... test
again with the -e
option.
When you open an Eclipse workspace from within a clearcase view and try to rename the project, you will often get the pop-up warning ... “Resource ‘project’ is out of sync with the file system”. If refreshing the project does not fix the problem, then do the following workaround: a. Open workspace WITHOUT being in a view b. Select the project in Project Explorer c. ClearCase -> Associate Project (project should now look like project [] ) d. Right click project -> Refresh (vob sub-folders should now be empty) e. Right click project -> Rename ... f. Enter New name
Now you can close the workspace, reopen it in a view and refresh the project. You may also dissociate the project if you prefer the project not to be associated with the vob.
This is not possible from HTML on. The closest what you can get is the accept-charset
attribute of the <form>
. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type
header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.
To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding
attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).
Update:
Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type
header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.
This should get you started:
R> qplot(hwy, cty, data = mpg) +
facet_grid(. ~ manufacturer) +
theme(strip.text.x = element_text(size = 8, colour = "orange", angle = 90))

jqxhr is a json object:
complete returns:
The jqXHR (in jQuery 1.4.x, XMLHTTPRequest) object and a string categorizing the status of the request ("success", "notmodified", "error", "timeout", "abort", or "parsererror").
see: jQuery ajax
so you would do:
jqxhr.status
to get the status
It's not enough to have just compile project("xy")

You need to configure root project to include all modules (or to call them subprojects but that might not be correct word here).
Create a settings.gradle file in the root of your project and add this:
include ':progressfragment'
to that file. Then sync Gradle and it should work.
Also one interesting side note: If you add ':unexistingProject' in settings.gradle (project that you haven't created yet), Gradle will create folder for this project after sync (at least in Android studio this is how it behaves). So, to avoid errors with settings.gradle when you create project from existing files, first add that line to file, sync and then put existing code in created folder. Unwanted behavior arising from this might be that if you delete the project folder and then sync folder will come back empty because Gradle sync recreated it since it is still listed in settings.gradle.
I came to add:
map(str.strip, string.split(','))
but saw it had already been mentioned by Jason Orendorff in a comment.
Reading Glenn Maynard's comment in the same answer suggesting list comprehensions over map I started to wonder why. I assumed he meant for performance reasons, but of course he might have meant for stylistic reasons, or something else (Glenn?).
So a quick (possibly flawed?) test on my box applying the three methods in a loop revealed:
[word.strip() for word in string.split(',')]
$ time ./list_comprehension.py
real 0m22.876s
map(lambda s: s.strip(), string.split(','))
$ time ./map_with_lambda.py
real 0m25.736s
map(str.strip, string.split(','))
$ time ./map_with_str.strip.py
real 0m19.428s
making map(str.strip, string.split(','))
the winner, although it seems they are all in the same ballpark.
Certainly though map (with or without a lambda) should not necessarily be ruled out for performance reasons, and for me it is at least as clear as a list comprehension.

Just copy/paste it into a php file and run it.
The easiest way to do it is to use the End
method, which is gives you the cell that you reach by pressing the end key and then a direction when you're on a cell (in this case B6). This won't give you what you expect if B6 or B7 is empty, though.
Dim start_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Range(start_cell, start_cell.End(xlDown)).Copy Range("[Workbook2.xlsx]Sheet1!A2")
If you can't use End
, then you would have to use a loop.
Dim start_cell As Range, end_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Set end_cell = start_cell
Do Until IsEmpty(end_cell.Offset(1, 0))
Set end_cell = end_cell.Offset(1, 0)
Loop
Range(start_cell, end_cell).Copy Range("[Workbook2.xlsx]Sheet1!A2")
If you want to delete same effect in input, you could add the following code as well as button.
input:focus {outline:0;}
Assuming that onMove
is an event handler, it is likely that its context is something other than the instance of MyContainer
, i.e. this
points to something different.
You can manually bind the context of the function during the construction of the instance via Function.bind
:
class MyContainer extends Component {
constructor(props) {
super(props);
this.onMove = this.onMove.bind(this);
this.test = "this is a test";
}
onMove() {
console.log(this.test);
}
}
Also, test !== testVariable
.
While this would not work for an entire application, it would work for an Activity and could be re-used for any other Activity. I've updated my code thanks to @FR073N to support other Views. I'm not sure about issues with Buttons
, RadioGroups
, etc. because those classes all extend TextView
so they should work just fine. I added a boolean conditional for using reflection because it seems very hackish and might notably compromise performance.
Note: as pointed out, this will not work for dynamic content! For that, it's possible to call this method with say an onCreateView
or getView
method, but requires additional effort.
/**
* Recursively sets a {@link Typeface} to all
* {@link TextView}s in a {@link ViewGroup}.
*/
public static final void setAppFont(ViewGroup mContainer, Typeface mFont, boolean reflect)
{
if (mContainer == null || mFont == null) return;
final int mCount = mContainer.getChildCount();
// Loop through all of the children.
for (int i = 0; i < mCount; ++i)
{
final View mChild = mContainer.getChildAt(i);
if (mChild instanceof TextView)
{
// Set the font if it is a TextView.
((TextView) mChild).setTypeface(mFont);
}
else if (mChild instanceof ViewGroup)
{
// Recursively attempt another ViewGroup.
setAppFont((ViewGroup) mChild, mFont);
}
else if (reflect)
{
try {
Method mSetTypeface = mChild.getClass().getMethod("setTypeface", Typeface.class);
mSetTypeface.invoke(mChild, mFont);
} catch (Exception e) { /* Do something... */ }
}
}
}
Then to use it you would do something like this:
final Typeface mFont = Typeface.createFromAsset(getAssets(),
"fonts/MyFont.ttf");
final ViewGroup mContainer = (ViewGroup) findViewById(
android.R.id.content).getRootView();
HomeActivity.setAppFont(mContainer, mFont);
Hope that helps.
If you need to do it with a set number of columns, H.B.'s way is best. But if you don't know how many columns you are dealing with until runtime, then the below code [read: hack] will work. I am not sure if there is a better solution with an unknown number of columns. It took me two days working at it off and on to get it, so I'm sticking with it regardless.
C#
public class ValueToBrushConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
int input;
try
{
DataGridCell dgc = (DataGridCell)value;
System.Data.DataRowView rowView = (System.Data.DataRowView)dgc.DataContext;
input = (int)rowView.Row.ItemArray[dgc.Column.DisplayIndex];
}
catch (InvalidCastException e)
{
return DependencyProperty.UnsetValue;
}
switch (input)
{
case 1: return Brushes.Red;
case 2: return Brushes.White;
case 3: return Brushes.Blue;
default: return DependencyProperty.UnsetValue;
}
}
public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
throw new NotSupportedException();
}
}
XAML
<UserControl.Resources>
<conv:ValueToBrushConverter x:Key="ValueToBrushConverter"/>
<Style x:Key="CellStyle" TargetType="DataGridCell">
<Setter Property="Background" Value="{Binding RelativeSource={RelativeSource Self}, Converter={StaticResource ValueToBrushConverter}}" />
</Style>
</UserControl.Resources>
<DataGrid x:Name="dataGrid" CellStyle="{StaticResource CellStyle}">

You need to use get_serving_url
from the Images API. As that page explains, you need to call create_gs_key()
first to get the key to pass to the Images API.

For me is the best solution but there's a way to avoid use jQuery.

You need to replace $(element).show(); and (element).show(); with $scope.loadingStatus = 'true'; and $scope.loadingStatus = 'false';
Than, you need to use this variable to set the ng-show attribute of the element.
Here's my hacky workaround - generate a console application (.NET Framework) that reads its own name and arguments, and then calls dotnet [nameOfExe].dll [args]
.
Of course this assumes that .NET is installed on the target machine.
Here's the code. Feel free to copy!
using System;
using System.Diagnostics;
using System.Text;
namespace dotNetLauncher
{
class Program
{
/*
If you make .NET Core applications, they have to be launched like .NET blah.dll args here
This is a convenience EXE file that launches .NET Core applications via name.exe
Just rename the output exe to the name of the .NET Core DLL file you wish to launch
*/
static void Main(string[] args)
{
var exePath = AppDomain.CurrentDomain.BaseDirectory;
var exeName = AppDomain.CurrentDomain.FriendlyName;
var assemblyName = exeName.Substring(0, exeName.Length - 4);
StringBuilder passInArgs = new StringBuilder();
foreach(var arg in args)
{
bool needsSurroundingQuotes = false;
if (arg.Contains(" ") || arg.Contains("\""))
{
passInArgs.Append("\"");
needsSurroundingQuotes = true;
}
passInArgs.Append(arg.Replace("\"","\"\""));
if (needsSurroundingQuotes)
{
passInArgs.Append("\"");
}
passInArgs.Append(" ");
}
string callingArgs = $"\"{exePath}{assemblyName}.dll\" {passInArgs.ToString().Trim()}";
var p = new Process
{
StartInfo = new ProcessStartInfo("dotnet", callingArgs)
{
UseShellExecute = false
}
};
p.Start();
p.WaitForExit();
}
}
}
Express version:
"dependencies": {
"body-parser": "^1.19.0",
"express": "^4.17.1"
}
Optional parameter are very much handy, you can declare and use them easily using express:
app.get('/api/v1/tours/:cId/:pId/:batchNo?', (req, res)=>{
console.log("category Id: "+req.params.cId);
console.log("product ID: "+req.params.pId);
if (req.params.batchNo){
console.log("Batch No: "+req.params.batchNo);
}
});
In the above code batchNo is optional. Express will count it optional because after in URL construction, I gave a '?' symbol after batchNo '/:batchNo?'
Now I can call with only categoryId and productId or with all three-parameter.

As a bonus for setting up a Title Case shortcut key Ctrl+kt (while holding Ctrl, press k and t), go to Preferences
--> Keybindings-User
If you have a blank file open and close with the square brackets:
[ { "keys": ["ctrl+k", "ctrl+t"], "command": "title_case" } ]
Otherwise if you already have stuff in there, just make sure if it comes after another command to prepend a comma "," and add:
{ "keys": ["ctrl+k", "ctrl+t"], "command": "title_case" }
The way we typically handle printing is to just open the new window with everything in it that needs to be sent to the printer. Then we have the user actually click on their browsers Print button.
This has always been acceptable in the past, and it sidesteps the security restrictions that Chilln is talking about.
If you want use the name of new window etc posting a form to this window, then the solution, that working in IE, FF, Chrome:
var ret = window.open("", "_blank");
ret.name = "NewFormName";
var myForm = document.createElement("form");
myForm.method="post";
myForm.action = "xyz.php";
myForm.target = "NewFormName";
...
consider
data={'fld':'hello'}
now
jsonify(data)
will yield {'fld':'hello'} and
json.dumps(data)
gives
"<html><body><p>{'fld':'hello'}</p></body></html>"
