Have you tried with a sub-query for every field:
UPDATE
MasterTbl
SET
TotalX = (SELECT SUM(X) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID),
TotalY = (SELECT SUM(Y) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID),
TotalZ = (SELECT SUM(Z) from DetailTbl where DetailTbl.MasterID = MasterTbl.ID)
WHERE
....
You need to identify the primary key in TableA in order to delete the correct record. The primary key may be a single column or a combination of several columns that uniquely identifies a row in the table. If there is no primary key, then the ROWID pseudo column may be used as the primary key.
DELETE FROM tableA
WHERE ROWID IN
( SELECT q.ROWID
FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum)
WHERE (LENGTH(q.memotext) NOT IN (8,9,10) OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date'));
Use only:
divID = "question-" + parseInt(i) + 1;
When "n" comes from html input field or is declared as string, you need to use explicit conversion.
var n = "1"; //type is string
var frstCol = 5;
lstCol = frstCol + parseInt(n);
If "n" is integer, don't need conversion.
n = 1; //type is int
var frstCol = 5, lstCol = frstCol + n;
You may group your library.available_until wheres area by grouping method of Codeigniter for without disable escaping where clauses.
$this->db
->select('*')
->from('library')
->where('library.rating >=', $form['slider'])
->where('library.votes >=', '1000')
->where('library.language !=', 'German')
->group_start() //this will start grouping
->where('library.available_until >=', date("Y-m-d H:i:s"))
->or_where('library.available_until =', "00-00-00 00:00:00")
->group_end() //this will end grouping
->where('library.release_year >=', $year_start)
->where('library.release_year <=', $year_end)
->join('rating_repo', 'library.id = rating_repo.id')

Creating a Guava BiMap and getting its inverted value is not so trivial.
A simple example:
import com.google.common.collect.BiMap;
import com.google.common.collect.HashBiMap;
public class BiMapTest {
public static void main(String[] args) {
BiMap<String, String> biMap = HashBiMap.create();
biMap.put("k1", "v1");
biMap.put("k2", "v2");
System.out.println("k1 = " + biMap.get("k1"));
System.out.println("v2 = " + biMap.inverse().get("v2"));
}
}
To get it done only with XAML you need to add Validation Rules for individual properties. But i would recommend you to go with code behind approach. In your code, define your specifications in properties setters and throw exceptions when ever it doesn't compliance to your specifications. And use error template to display your errors to user in UI. Your XAML will look like this
<Window x:Class="WpfApplication1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<Style x:Key="CustomTextBoxTextStyle" TargetType="TextBox">
<Setter Property="Foreground" Value="Green" />
<Setter Property="MaxLength" Value="40" />
<Setter Property="Width" Value="392" />
<Style.Triggers>
<Trigger Property="Validation.HasError" Value="True">
<Trigger.Setters>
<Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self},Path=(Validation.Errors)[0].ErrorContent}"/>
<Setter Property="Background" Value="Red"/>
</Trigger.Setters>
</Trigger>
</Style.Triggers>
</Style>
</Window.Resources>
<Grid>
<TextBox Name="tb2" Height="30" Width="400"
Text="{Binding Name, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, ValidatesOnExceptions=True}"
Style="{StaticResource CustomTextBoxTextStyle}"/>
</Grid>
Code Behind:
public partial class MainWindow : Window
{
private ExampleViewModel m_ViewModel;
public MainWindow()
{
InitializeComponent();
m_ViewModel = new ExampleViewModel();
DataContext = m_ViewModel;
}
}
public class ExampleViewModel : INotifyPropertyChanged
{
private string m_Name = "Type Here";
public ExampleViewModel()
{
}
public string Name
{
get
{
return m_Name;
}
set
{
if (String.IsNullOrEmpty(value))
{
throw new Exception("Name can not be empty.");
}
if (value.Length > 12)
{
throw new Exception("name can not be longer than 12 charectors");
}
if (m_Name != value)
{
m_Name = value;
OnPropertyChanged("Name");
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
}
}
sep='\t'
is often used for Tab-delimited file.
Try this:
npm install -g tsd
npm i
and npm start
You shouldn't overload the templates with complex logic, it's a bad practice. Remember to always keep it simple!
The better approach would be to extract this logic into reusable function on your $rootScope
:
.run(function ($rootScope) {
$rootScope.inArray = function (item, array) {
return (-1 !== array.indexOf(item));
};
})
Then, use it in your template:
<li ng-class="{approved: inArray(jobSet, selectedForApproval)}"></li>
I think everyone will agree that this example is much more readable and maintainable.
In my and possibly @BIOHAZARD case it was nginx proxy timeout
. In default it's 60
sec without activity in socket
I changed it to 24h in nginx
and it resolved problem
proxy_read_timeout 86400s;
proxy_send_timeout 86400s;
If you are able to use the bash shell, you can consider simply running the R code from within a bash script and piping the stdout and stderr streams to a file. Here is an example using a heredoc:
File: test.sh
#!/bin/bash
# this is a bash script
echo "Hello World, this is bash"
test1=$(echo "This is a test")
echo "Here is some R code:"
Rscript --slave --no-save --no-restore - "$test1" <<EOF
## R code
cat("\nHello World, this is R\n")
args <- commandArgs(TRUE)
bash_message<-args[1]
cat("\nThis is a message from bash:\n")
cat("\n",paste0(bash_message),"\n")
EOF
# end of script
Then when you run the script with both stderr and stdout piped to a log file:
$ chmod +x test.sh
$ ./test.sh
$ ./test.sh &>test.log
$ cat test.log
Hello World, this is bash
Here is some R code:
Hello World, this is R
This is a message from bash:
This is a test
Other things to look at for this would be to try simply pipping the stdout and stderr right from the R heredoc into a log file; I haven't tried this yet but it will probably work too.
This feature already exists in Ubuntu and Debian, in the command-not-found
package.
use following command if you installed in globally,
npm uninstall -g angular-cli
WHERE dates BETWEEN (convert(datetime, '2012-12-12',110) AND (convert(datetime, '2012-12-12',110))
map.keySet()
will return you all the keys. If you want the keys to be sorted, you might consider a TreeMap
Try with these steps :
npm rm -g create-react-app
npm install -g create-react-app
npx create-react-app my-app
Definitely this works!!
This works:
$string = 'A B C D';
$arr = preg_split('/[\s]+/', $string);
use php implode()
or serialize()
python 3.2
>>>> from itertools import chain
>>>> eg=sorted(list(set(list(chain(*eg)))), reverse=True)
[7, 6, 5, 4, 3, 2, 1]
##### eg contain 2 list within a list. so if you want to use set() function
you should flatten the list like [1, 2, 3, 4, 4, 5, 6, 7]
>>> res= list(chain(*eg)) # [1, 2, 3, 4, 4, 5, 6, 7]
>>> res1= set(res) # [1, 2, 3, 4, 5, 6, 7]
>>> res1= sorted(res1,reverse=True)
Use the Apache Commons CLI library commandline.getArgs() to get arg1, arg2, arg3, and arg4. Here is some code:

System.out.println("Option test is present. This is a flag option.");
}
{
String[] remainder = commandLine.getArgs();
System.out.print("Remaining arguments: ");
for (String argument : remainder)
{
System.out.print(argument);
System.out.print(" ");
}
System.out.println();
}
}
catch (ParseException exception)
{
System.out.print("Parse error: ");
System.out.println(exception.getMessage());
}
}
It's possible to redirect to another view with angular-ui-router. For this purpose, we have the method $state.go("target_view")
. For example:
---- app.js -----
var app = angular.module('myApp', ['ui.router']);
app.config(function ($stateProvider, $urlRouterProvider) {
// Otherwise
$urlRouterProvider.otherwise("/");
$stateProvider
// Index will decide if redirects to Login or Dashboard view
.state("index", {
url: ""
controller: 'index_controller'
})
.state('dashboard', {
url: "/dashboard",
controller: 'dashboard_controller',
templateUrl: "views/dashboard.html"
})
.state('login', {
url: "/login",
controller: 'login_controller',
templateUrl: "views/login.html"
});
});
// Associate the $state variable with $rootScope in order to use it with any controller
app.run(function ($rootScope, $state, $stateParams) {
$rootScope.$state = $state;
$rootScope.$stateParams = $stateParams;
});
app.controller('index_controller', function ($scope, $log) {
/* Check if the user is logged prior to use the next code */
if (!isLoggedUser) {
$log.log("user not logged, redirecting to Login view");
// Redirect to Login view
$scope.$state.go("login");
} else {
// Redirect to dashboard view
$scope.$state.go("dashboard");
}
});

To bad CSS doesn't support cross-browser multiline clamping, only webkit seems to be pushing it.
You could try and use a simple Javascript ellipsis library like Ellipsity on github the source code is very clean and small so if you do need to make any additional changes it should be quite easy.
The Easiest way to do it is to have good site structure and write it as a constant.
DEFINE("BACK_ROOT","/var/www/");
One thing you might want to look at is the Commons DBCP project. It provides a BasicDataSource that is configured fairly similarly to your example. To use that you need the database vendor's JDBC JAR in your classpath and you have to specify the vendor's driver class name and the database URL in the proper format.
Edit:
If you want to configure a BasicDataSource
for MySQL, you would do something like this:
BasicDataSource dataSource = new BasicDataSource();
dataSource.setDriverClassName("com.mysql.jdbc.Driver");
dataSource.setUsername("username");
dataSource.setPassword("password");
dataSource.setUrl("jdbc:mysql://<host>:<port>/<database>");
dataSource.setMaxActive(10);
dataSource.setMaxIdle(5);
dataSource.setInitialSize(5);
dataSource.setValidationQuery("SELECT 1");
Code that needs a DataSource
can then use that.
Most likely the TinyMce editor is adding its own formatting to the post. You'll need to see how you can escape TinyMce's editing abilities. The code works fine for me. Is it a wordpress blog?
Best alternative:
public static readonly byte[] ZeroHash = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 };
You did not add #
before id of the button. You do not have right selector in your jquery code. So jquery is never execute in your button click. its submitted your form directly not passing any ajax request.
See documentation: http://api.jquery.com/category/selectors/
its your friend.
Try this:
It seems that id: $("#Shareitem").val()
is wrong if you want to pass the value of
<input type="hidden" name="id" value="" id="id">
you need to change this line:
id: $("#Shareitem").val()
by
id: $("#id").val()
All together:
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script>
$(document).ready(function(){
$("#Shareitem").click(function(e){
e.preventDefault();
$.ajax({type: "POST",
url: "/imball-reagens/public/shareitem",
data: { id: $("#Shareitem").val(), access_token: $("#access_token").val() },
success:function(result){
$("#sharelink").html(result);
}});
});
});
</script>
You can change the code by using class definition for the i
element:
<a href="javascript:void"><i class="fa fa-plus-circle"></i>Category 1</a>
Then you can switch the classes rapresenting the plus/minus state using toggleClass
with multiple classes:
$('#category-tabs li a').click(function(){
$(this).next('ul').slideToggle('500');
$(this).find('i').toggleClass('fa-plus-circle fa-minus-circle');
});
I profiled a few methods to move an item within the same list with timeit. Here are the ones to use if j>i:
+---------------------------------+ ¦ 14.4usec ¦ x[i:i]=x.pop(j), ¦ ¦ 14.5usec ¦ x[i:i]=[x.pop(j)] ¦ ¦ 15.2usec ¦ x.insert(i,x.pop(j)) ¦ +---------------------------------+
and here the ones to use if j<=i:
+--------------------------------------+ ¦ 14.4usec ¦ x[i:i]=x[j],;del x[j] ¦ ¦ 14.4usec ¦ x[i:i]=[x[j]];del x[j] ¦ ¦ 15.4usec ¦ x.insert(i,x[j]);del x[j] ¦ +--------------------------------------+
Not a huge difference if you only use it a few times, but if you do heavy stuff like manual sorting, it's important to take the fastest one. Otherwise, I'd recommend just taking the one that you think is most readable.

I usually construct custom objects in these loops, and then add these objects to an array that I can easily manipulate, sort, export to CSV, etc.:
# Construct an out-array to use for data export
$OutArray = @()
# The computer loop you already have
foreach ($server in $serverlist)
{
# Construct an object
$myobj = "" | Select "computer", "Speed", "Regcheck"
# Fill the object
$myobj.computer = $computer
$myobj.speed = $speed
$myobj.regcheck = $regcheck
# Add the object to the out-array
$outarray += $myobj
# Wipe the object just to be sure
$myobj = $null
}
# After the loop, export the array to CSV
$outarray | export-csv "somefile.csv"
According to this: http://www.vistax64.com/vista-installation-setup/33219-regsvr32-error-0x80004005.html
Run it in a elevated command prompt.
Here is how I do it by using HashSet
HashSet<String> hs = new HashSet<string>(new String[] { "Pluto", "Earth", "Neptune" });
String[] arr =
{
"Pluto",
"Earth",
"Neptune",
"Jupiter",
"Saturn",
"Mercury",
"Pluto",
"Earth",
"Neptune",
"Jupiter",
"Saturn",
"Mercury",
// etc.
};
ICollection<String> coll = arr;
String[] arrStrFiltered = coll.Where(str => hs.Contains(str)).ToArray();
HashSet is basically almost to O(1) so your complexity remains O(n).
There are a lot of great answers here, but I want to come with my 50 cents.
What all of these answers are missing is a simple analogy which would work for a person who just starts his journey in the programming languages.
Hopefully, I will fill this gap with this analogy:
Feel the difference with a sentence creation.
If I have a sentence "I like cheese"
, I can tell you clearly and loudly (literally, or verbatim): I like cheese.
This is my literal (word by word) creation of the sentence.
All other ways are some tricky ways of making you to understand of what sentence I created exactly. For example, I tell you:
"I"
, the object is "cheese"
, and the predicate is "to like"
.
This is another way of YOU to learn without any ambiguities the very same sentence: "I like cheese".Or,
In this case, you also come to the same result: you know exactly what the sentence is.
You can devise any other methods which would differ from "word-by-word" sentence creation (LITERAL), and which would be INDIRECT (non literal, non verbatim) method of sentence creation.
I think this is the core concept which lays here.
Have you tried:
eval $cmd
For the follow-on question of how to escape *
since it has special meaning when it's naked or in double quoted strings: use single quotes.
MYSQL='mysql AMORE -u username -ppassword -h localhost -e'
QUERY="SELECT "'*'" FROM amoreconfig" ;# <-- "double"'single'"double"
eval $MYSQL "'$QUERY'"
Bonus: It also reads nice: eval mysql query ;-)
If you are suffering from "ADB not responding. If you’d like to retry, then please manually kill ‘adb’ and click ‘Restart’ or terminal appear Syntax error: “)” unexpected" then perhaps you are using 32bit OS and platform-tools has updated up 23.1. The solution is to go back to the platform-tools 23.0.1.
You can download the platform-tools 23.0.1 for Linux here , for windowns here and Mac here
After the download, go to your sdk location > platform-tools folder to delete old platform-tools in sdk and paste down into the downloaded one.
Woohooo ... it should work.
This is a bug with latest ADT.
pip is installed by default when we install Python in windows.
After setting up the environment variables path for python executables, we can run python interpreter from the command line on windows CMD
After that, we can directly use the python command with pip option to install further packages as following:-
C:\ python -m pip install python_module_name
This will install the module using pip.
This is old thread, so I figured for anyone looking for a modern answer, I would suggest using Object.keys();
var myDiv = document.getElementById("myDiv");
var css = {
"font-size": "14px",
"color": "#447",
"font-family": "Arial",
"text-decoration": "underline"
};
function applyInlineStyles(obj) {
var result = "";
Object.keys(obj).forEach(function (prop) {
result += prop + ": " + obj[prop] + "; ";
});
return result;
}
myDiv.style = applyInlineStyles(css);
Similar to karim's, but with print_r which has a much small output and I find is usually all you need:
function PrintR($var) {
echo '<pre>';
print_r($var);
echo '</pre>';
}
In my situation, in order to include color.sh
from the same directory in init.sh
, I had to do something as follows.
. ./color.sh
Not sure why the ./
and not color.sh
directly. The content of color.sh
is as follows.
RED=`tput setaf 1`
GREEN=`tput setaf 2`
BLUE=`tput setaf 4`
BOLD=`tput bold`
RESET=`tput sgr0`
Making use of File color.sh
does not error but, the color do not display. I have tested this in Ubuntu 18.04
and the Bash
version is:
GNU bash, version 4.4.19(1)-release (x86_64-pc-linux-gnu)
Ok, maybe I'm missing something here, but this is the way I do it:
public static Byte[] ToByteArray(this Stream stream) {
Int32 length = stream.Length > Int32.MaxValue ? Int32.MaxValue : Convert.ToInt32(stream.Length);
Byte[] buffer = new Byte[length];
stream.Read(buffer, 0, length);
return buffer;
}
you can run something like this (paste the code bellow in a .bat, or if you want it to run interractively replace the %%
by %
:
for %%i in (c:\directory\*.xls) do ssconvert %%i %%i.xlsx
If you can run powershell it will be :
Get-ChildItem -Path c:\directory -filter *.xls | foreach {ssconvert $($_.FullName) $($_.baseName).xlsx }

tl;dr: You don't have to remove the slashes, you have nested JSON, and hence have to decode the JSON twice: DEMO (note I used double slashes in the example, because the JSON is inside a JS string literal).
I assume that your actual JSON looks like
{"data":"{\n \"taskNames\" : [\n \"01 Jan\",\n \"02 Jan\",\n \"03 Jan\",\n \"04 Jan\",\n \"05 Jan\",\n \"06 Jan\",\n \"07 Jan\",\n \"08 Jan\",\n \"09 Jan\",\n \"10 Jan\",\n \"11 Jan\",\n \"12 Jan\",\n \"13 Jan\",\n \"14 Jan\",\n \"15 Jan\",\n \"16 Jan\",\n \"17 Jan\",\n \"18 Jan\",\n \"19 Jan\",\n \"20 Jan\",\n \"21 Jan\",\n \"22 Jan\",\n \"23 Jan\",\n \"24 Jan\",\n \"25 Jan\",\n \"26 Jan\",\n \"27 Jan\"]}"}
I.e. you have a top level object with one key, data
. The value of that key is a string containing JSON itself. This is usually because the server side code didn't properly create the JSON. That's why you see the \"
inside the string. This lets the parser know that "
is to be treated literally and doesn't terminate the string.
So you can either fix the server side code, so that you don't double encode the data, or you have to decode the JSON twice, e.g.
var data = JSON.parse(JSON.parse(json).data));
In the file you put in /etc/init.d/
you have to set it executable with:
chmod +x /etc/init.d/start_my_app
Thanks to @meetamit, if this does not run you have to create a symlink to /etc/rc.d/
ln -s /etc/init.d/start_my_app /etc/rc.d/
Please note that on latest Debian, this will not work as your script have to be LSB compliant (provide, at least, the following actions: start, stop, restart, force-reload, and status): https://wiki.debian.org/LSBInitScripts
As a note, you should put the absolute path of your script instead of a relative one, it may solves unexpected issues:
/var/myscripts/start_my_app
And don't forget to add on top of that file:
#!/bin/sh
You can use 2 ways for solve this problem: 1) After the head tag
<head>
<meta http-equiv="refresh" content="600">
</head>
2) If your page hasn't head tag you must use Javascript to implement
<script type="text/javascript">
function RefreshPage()
{
window.location.reload()
}
</script>
My contact:
In your class, where you implement the static function, you can call a private\public method from this class. The private\public method can access the getResources.
for example:
public class Text {
public static void setColor(EditText et) {
et.resetColor(); // it works
// ERROR
et.setTextColor(getResources().getColor(R.color.Black)); // ERROR
}
// set the color to be black when reset
private void resetColor() {
setTextColor(getResources().getColor(R.color.Black));
}
}
and from other class\activity, you can call:
Text.setColor('some EditText you initialized');
subprocess.check_output() returns bytes.
so you need to convert '\n' to bytes as well:
f.write (plaintext + b'\n')
hope this helps
Basically, you can include your JAR files in three different ways. The last one is remote library that is using https://bintray.com/ jcenter online repository. But, if you do it in one of the two other ways, the JAR file will be included physically in your project. Please read this link https://stackoverflow.com/a/35369267/5475941 for more information. In this post I explained how to import your JAR file in Android studio and I explained all possible ways.
In summary, if it is like this (local address), they are downloaded and these JAR files are physically in the project:
But, if it is an internet address like this, they are remote libraries (bintray.com jcenter part) and they will be used remotely:
I hope it helps.
Edit > Advanced > View White Space. The keyboard shortcut is CTRL+R, CTRL+W. The command is called Edit.ViewWhiteSpace
.
It works in all Visual Studio versions at least since Visual Studio 2010, the current one being Visual Studio 2019 (at time of writing). In Visual Studio 2013, you can also use CTRL+E, S or CTRL+E, CTRL+S.
By default, end of line markers are not visualized. This functionality is provided by the End of the Line extension.
First, please do not use extract(), it can be a security problem because it is easy to manipulate POST parameters
In addition, you don't have to use variable variable names (that sounds odd), instead:
foreach($_POST as $key => $value) {
echo "POST parameter '$key' has '$value'";
}
To ensure that you have only parameters beginning with 'item_name' you can check it like so:
$param_name = 'item_name';
if(substr($key, 0, strlen($param_name)) == $param_name) {
// do something
}
try delete from mysql.db where user = 'jack'
and then create a user
The code should be like given below
String selectSQL = "SELECT IFNULL(tbl.column, \"\") AS column FROM MySQL_table AS tbl";
Statement st = ...;
Result set rs = st.executeQuery(selectSQL);
One thing you could do is change Sort
so it makes better use of lambdas.
public enum SortDirection { Ascending, Descending }
public void Sort<TKey>(ref List<Employee> list,
Func<Employee, TKey> sorter, SortDirection direction)
{
if (direction == SortDirection.Ascending)
list = list.OrderBy(sorter);
else
list = list.OrderByDescending(sorter);
}
Now you can specify the field to sort when calling the Sort
method.
Sort(ref employees, e => e.DOB, SortDirection.Descending);
I was using a duplicate Foreign Key Name.
Renaming the FK name solved my problem.
Clarification:
Both tables had a constraint called PK1, FK1, etc. Renaming them/making the names unique solved the problem.
Struct can be used to improve garbage collection performance. While you usually don't have to worry about GC performance, there are scenarios where it can be a killer. Like large caches in low latency applications. See this post for an example:
http://00sharp.wordpress.com/2013/07/03/a-case-for-the-struct/
You have to use .onload
let canvas = document.getElementById("myCanvas");
let ctx = canvas.getContext("2d");
const drawImage = (url) => {
const image = new Image();
image.src = url;
image.onload = () => {
ctx.drawImage(image, 0, 0)
}
}
Here's Why
If you are loading the image first after the canvas has already been created then the canvas won't be able to pass all the image data to draw the image. So you need to first load all the data that came with the image and then you can use drawImage()
Use #include <windows.h>
instead of #include <windef.h>
.
From the windows.h
wikipedia page:
There are a number of child header files that are automatically included with
windows.h
. Many of these files cannot simply be included by themselves (they are not self-contained), because of dependencies.
windef.h
is one of the files automatically included with windows.h
.
Also, you can display current position by "drag" listener and write it to visible or hidden field. You may also need to store zoom. Here's copy&paste from working tool:
function map_init() {
var lt=48.451778;
var lg=31.646305;
var myLatlng = new google.maps.LatLng(lt,lg);
var mapOptions = {
center: new google.maps.LatLng(lt,lg),
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById('map'),mapOptions);
var marker = new google.maps.Marker({
position:myLatlng,
map:map,
draggable:true
});
google.maps.event.addListener(
marker,
'drag',
function() {
document.getElementById('lat1').innerHTML = marker.position.lat().toFixed(6);
document.getElementById('lng1').innerHTML = marker.position.lng().toFixed(6);
document.getElementById('zoom').innerHTML = mapObject.getZoom();
// Dynamically show it somewhere if needed
$(".x").text(marker.position.lat().toFixed(6));
$(".y").text(marker.position.lng().toFixed(6));
$(".z").text(map.getZoom());
}
);
}
I'm using Linux Mint 18.2 of this writing. I had a similar issue; when trying to load myphpadmin, it said: "1045 - Access denied for user 'root'@'localhost' (using password: NO)"
I found the file in the /opt/lampp/phpmyadmin directory
. I opened the config.inc.php file with my text editor and typed in the correct password. Saved it, and launched it successfully. Profit!
I was having problems with modifying folders and files, I had to change permission to access all my files in /opt/lampp/ directory. I hope this helps someone in the future.
I managed to allow all my requisite sites with this header:
header("Content-Security-Policy: default-src *; style-src 'self' 'unsafe-inline'; font-src 'self' data:; script-src 'self' 'unsafe-inline' 'unsafe-eval' stackexchange.com");
What you are trying to do can almost certainly be achieved with a set.
>>> x = set([1,2,3])
>>> x.add(2)
>>> x
set([1, 2, 3])
>>> x.add(4)
>>> x.add(4)
>>> x
set([1, 2, 3, 4])
>>>
using a set's add method you can build your unique set of ids very quickly. Or if you already have a list
unique_ids = set(id_list)
as for getting your inputs in numeric form you can do something like
>>> ids = [int(n) for n in '350882 348521 350166\r\n'.split()]
>>> ids
[350882, 348521, 350166]
On Windows (with Cygwin) try
cat /dev/clipboard
or echo "foo" > /dev/clipboard
as mentioned in this article.
You can set HorizontalAlignment
to Left, set your MaxWidth
and then bind Width
to the ActualWidth
of the parent element:
<Page
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<StackPanel Name="Container">
<TextBox Background="Azure"
Width="{Binding ElementName=Container,Path=ActualWidth}"
Text="Hello" HorizontalAlignment="Left" MaxWidth="200" />
</StackPanel>
</Page>
Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable
jQuery(function(){
//here it is a closure variable
var a_href;
$('sth a').on('click', function(e){
a_href = $(this).attr('href');
console.log(a_href);
//output is "home"
e.preventDefault();
}
})
To make the variable global, one solution is to declare the variable in global scope
var a_href;
jQuery(function(){
$('sth a').on('click', function(e){
a_href = $(this).attr('href');
console.log(a_href);
//output is "home"
e.preventDefault();
}
})
another is to set the variable as a property of the window object
window.a_href = $(this).attr('href')
Why console printing undefined
You are getting the output as undefined
because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a
element is clicked till that time the variable will have the value undefined
. If you are not declaring the variable it will throw a ReferenceError
If you're happy with the Effective Java implementation recommended by dmeister, you can use a library call instead of rolling your own:
@Override
public int hashCode() {
return Objects.hashCode(this.firstName, this.lastName);
}
This requires either Guava (com.google.common.base.Objects.hashCode
) or the standard library in Java 7 (java.util.Objects.hash
) but works the same way.
If you want to use rollback, then use start transaction and otherwise forget all those things,
By default, MySQL automatically commits the changes to the database.
To force MySQL not to commit these changes automatically, execute following:
SET autocommit = 0;
//OR
SET autocommit = OFF
To enable the autocommit mode explicitly:
SET autocommit = 1;
//OR
SET autocommit = ON;
EXIT_FAILURE
, either in a return statement in main
or as an argument to exit()
, is the only portable way to indicate failure in a C or C++ program. exit(1)
can actually signal successful termination on VMS, for example.
If you're going to be using EXIT_FAILURE
when your program fails, then you might as well use EXIT_SUCCESS
when it succeeds, just for the sake of symmetry.
On the other hand, if the program never signals failure, you can use either 0
or EXIT_SUCCESS
. Both are guaranteed by the standard to signal successful completion. (It's barely possible that EXIT_SUCCESS
could have a value other than 0, but it's equal to 0 on every implementation I've ever heard of.)
Using 0
has the minor advantage that you don't need #include <stdlib.h>
in C, or #include <cstdlib>
in C++ (if you're using a return
statement rather than calling exit()
) -- but for a program of any significant size you're going to be including stdlib directly or indirectly anyway.
For that matter, in C starting with the 1999 standard, and in all versions of C++, reaching the end of main()
does an implicit return 0;
anyway, so you might not need to use either 0
or EXIT_SUCCESS
explicitly. (But at least in C, I consider an explicit return 0;
to be better style.)
(Somebody asked about OpenVMS. I haven't used it in a long time, but as I recall odd status values generally denote success while even values denote failure. The C implementation maps 0
to 1
, so that return 0;
indicates successful termination. Other values are passed unchanged, so return 1;
also indicates successful termination. EXIT_FAILURE
would have a non-zero even value.)
Don't forget that if you are concerned about reading in a file that might have huge lines that could swamp your RAM during runtime, you can always read the file piece-meal. See "Why slurping a file is bad".
File.open('file_path', 'rb') do |io|
while chunk = io.read(16 * 1024) do
something_with_the chunk
# like stream it across a network
# or write it to another file:
# other_io.write chunk
end
end
Please make sure that you have specified your class/package in TestNG.xml file.

Assuming that "external factors" you are referring to could be picked up by media queries, you could use them - adjustments will likely have to be limited to a set of predefined sizes.
Since id is an attribute don't create an id element, just do this:
myPara.setAttribute("id", "id_you_like");
This a late answer, but I am putting it out there anyway for any new programmers to see:
If you do not want to use regular expressions, and do not wish to rely on a third party library, you can use this method instead, which takes between 89920 and 100113 nanoseconds in a 2.80 GHz CPU (less than a millisecond). It's not as pretty as Simon Nickerson's example, but it works:
/**

* length(s).
*
* @param string
* the string to split.
* @param defaultLength
* the default length used for any extra substrings. If set to
* <code>0</code>, the last substring will start at the sum of
* <code>lengths</code> and end at the end of <code>string</code>.
* @param lengths
* the lengths of each substring in order. If any substring is not
* provided a length, it will use <code>defaultLength</code>.
* @return the array of strings computed by splitting this string into the given
* substring lengths.
*/
public static String[] divideString(String string, int defaultLength, int... lengths) {
java.util.ArrayList<String> parts = new java.util.ArrayList<String>();
if (lengths.length == 0) {
parts.add(string.substring(0, defaultLength));
string = string.substring(defaultLength);
while (string.length() > 0) {
if (string.length() < defaultLength) {
parts.add(string);
break;
}
parts.add(string.substring(0, defaultLength));
string = string.substring(defaultLength);
}
} else {
for (int i = 0, temp; i < lengths.length; i++) {
temp = lengths[i];
if (string.length() < temp) {
parts.add(string);
break;
}
parts.add(string.substring(0, temp));
string = string.substring(temp);
}
while (string.length() > 0) {
if (string.length() < defaultLength || defaultLength <= 0) {
parts.add(string);
break;
}
parts.add(string.substring(0, defaultLength));
string = string.substring(defaultLength);
}
}
return parts.toArray(new String[parts.size()]);
}
For Swift 3 you can use the following:
func setupSpinner(){
spinner = UIActivityIndicatorView(frame: CGRect(x: 0, y: 0, width: 40, height:40))
spinner.color = UIColor(Colors.Accent)
self.spinner.center = CGPoint(x:UIScreen.main.bounds.size.width / 2, y:UIScreen.main.bounds.size.height / 2)
self.view.addSubview(spinner)
spinner.hidesWhenStopped = true
}
The Allow-Control-Allow-Origin plugin for Chrome does not work. This is for MacOS
I added alias chrome='open -n -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --args --user-data-dir --disable-web-security'
to my .profile as an alias.
The other commands will disable my other extensions and this will boot your normal chrome with cors disabled
So if you want something unique to the device itself, TM.getDeviceId()
should be sufficient.
Here is the code which shows how to get Telephony manager ID. The android Device ID that you are using can change on factory settings and also some manufacturers have issue in giving unique id.
TelephonyManager tm =
(TelephonyManager) this.getSystemService(Context.TELEPHONY_SERVICE);
String androidId = Secure.getString(this.getContentResolver(), Secure.ANDROID_ID);
Log.d("ID", "Android ID: " + androidId);
Log.d("ID", "Device ID : " + tm.getDeviceId());
Be sure to take permissions for TelephonyManager
by using
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
Exception code c0000005
is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:
N
and you access elements with index >=N
.To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.
You can get desired behavior by listening when user hit "Done" button on keyboard, also checkout other tips about working with EditText in my post "Android form validation - the right way"
Sample code:
mTextView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
validateAndSubmit();
return true;
}
return false;
}});

I find it more useful to have null in the updated_at column when the record is been created but has never been modified. It reduces the db size (ok, just a little) and its possible to see it at the first sight that the data has never been modified.
As of this I use:
$table->timestamp('created_at')->useCurrent();
$table->timestamp('updated_at')->default(DB::raw('NULL ON UPDATE CURRENT_TIMESTAMP'))->nullable();

It was mentioned as a comment by @henri-chan, but I think it deserves some more attention:
When you update the content of an element with new html using jQuery/javascript, and this new html contains <script>
tags, those are executed synchronously and thus triggering this error. Same goes for stylesheets.
You know this is happening when you see (multiple) scripts or stylesheets being loaded as XHR
in the console window. (firefox).
What kind of object are you using for databinding? Typically I use Collection<T>, List<T>, or Queue<T> (depending on circumstances). These are relatively easy to sort using a custom delegate. See MSDN documentation on the Comparison(T) delegate.
you need to reconfigure your tnsnames.ora so that it can point to your hostname after that listener will be able to pick the new hostname. after which check the status of your listener lsnrctl status and start listener lsnrctl start then register your listener. Alter system register
Despite the question being about requests, I find this very easy to do with pycurl CURLOPT_TIMEOUT or CURLOPT_TIMEOUT_MS.
No threading or signaling required:
import pycurl

url = 'http://www.example.com/example.zip'
timeout_ms = 1000
raw = StringIO.StringIO()
c = pycurl.Curl()
c.setopt(pycurl.TIMEOUT_MS, timeout_ms) # total timeout in milliseconds
c.setopt(pycurl.WRITEFUNCTION, raw.write)
c.setopt(pycurl.NOSIGNAL, 1)
c.setopt(pycurl.URL, url)
c.setopt(pycurl.HTTPGET, 1)
try:
c.perform()
except pycurl.error:
traceback.print_exc() # error generated on timeout
pass # or just pass if you don't want to print the error
Create a local branch
git checkout -b local-branch-name

In pre-commit/post-checkout an option would be to use "mtree" (FreeBSD), or "fmtree" (Ubuntu) utility which "compares a file hierarchy against a specification, creates a specification for a file hierarchy, or modifies a specification."
The default set are flags, gid, link, mode, nlink, size, time, type, and uid. This can be fitted to the specific purpose with -k switch.

For primitive values like numbers and strings this is an easy solution:
a = [1,2,3]
b = [3,2,1]
a.sort().toString() == b.sort().toString()
The call to sort()
will ensure that the order of the elements does not matter. The toString()
call will create a string with the values comma separated so both strings can be tested for equality.
I try my darned best to write exception-safe code, yes.
That means I take care to keep an eye on which lines can throw. Not everyone can, and it is critically important to keep that in mind. The key is really to think about, and design your code to satisfy, the exception guarantees defined in the standard.
Can this operation be written to provide the strong exception guarantee? Do I have to settle for the basic one? Which lines may throw exceptions, and how can I ensure that if they do, they don't corrupt the object?
You can simply use shell commands. If you want to suppress echoing the output, use the "@" sign. For example:
clean:
@if [ "test" = "test" ]; then\
echo "Hello world";\
fi
Note that the closing ";" and "\" are necessary.
If repeating the same code is the issue, write an extension method on the String class that encapsulates the splitting logic.

You can rename/remove master on remote, but this will be an issue if lots of people have based their work on the remote master branch and have pulled that branch in their local repo.
That might not be the case here since everyone seems to be working on branch 'seotweaks
'.
In that case you can:
git remote --show may not work.
(Make a git remote show
to check how your remote is declared within your local repo. I will assume 'origin
')
(Regarding GitHub, house9 comments: "I had to do one additional step, click the 'Admin
' button on GitHub and set the 'Default Branch
' to something other than 'master
', then put it back afterwards")
git branch -m master master-old # rename master on local
git push origin :master # delete master on remote
git push origin master-old # create master-old on remote
git checkout -b master seotweaks # create a new local master on top of seotweaks
git push origin master # create master on remote
But again:
reset --hard
their local master to the remote/master branch they will fetch, and forget about their current master.You're almost there. As you can see, the onItemSelected
will give you a position
parameter, you can use this to retrieve the object from your adapter, as in getItemAtPosition(position)
.
Example:
spinner.setOnItemSelectedListener(this);
...
public void onItemSelected(AdapterView<?> parent, View view, int pos,long id) {
Toast.makeText(parent.getContext(),
"OnItemSelectedListener : " + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_SHORT).show();
}
This will put a message on screen, with the selected item printed by its toString() method.
Try this code:
WebElement userName = pathfinderdriver.switchTo().activeElement();
userName.sendKeys(Keys.TAB);
I really like grep() and grepl() for this purpose.
grep() returns a vector of integers, which indicate where matches are.
yo <- c("a", "a", "b", "b", "c", "c")
grep("b", yo)
[1] 3 4
grepl() returns a logical vector, with "TRUE" at the location of matches.
yo <- c("a", "a", "b", "b", "c", "c")
grepl("b", yo)
[1] FALSE FALSE TRUE TRUE FALSE FALSE
These functions are case-sensitive.
db.getCollection('orders').aggregate([
{$group: {
_id: {name: "$name"},
uniqueIds: {$addToSet: "$_id"},
count: {$sum: 1}
}
},
{$match: {
count: {"$gt": 1}
}
}
])
First Group Query the group according to the fields.
Then we check the unique Id and count it, If count is greater then 1 then the field is duplicate in the entire collection so that thing is to be handle by $match query.
It is easy to create a self-signed certificate, import it, and bind it to your website.
1.) Create a self-signed certificate:
Run the following 4 commands, one at a time, from an elevated Command Prompt:
cd C:\Program Files (x86)\Windows Kits\8.1\bin\x64
makecert -r -n "CN=localhost" -b 01/01/2000 -e 01/01/2099 -eku 1.3.6.1.5.5.7.3.3 -sv localhost.pvk localhost.cer
cert2spc localhost.cer localhost.spc
pvk2pfx -pvk localhost.pvk -spc localhost.spc -pfx localhost.pfx
2.) Import certificate to Trusted Root Certification Authorities store:
start --> run --> mmc.exe --> Certificates plugin --> "Trusted Root Certification Authorities" --> Certificates
Right-click Certificates --> All Tasks --> Import Find your "localhost" Certificate at C:\Program Files (x86)\Windows Kits\8.1\bin\x64\
3.) Bind certificate to website:
start --> (IIS) Manager --> Click on your Server --> Click on Sites --> Click on your top level site --> Bindings
Add or edit a binding for https and select the SSL certificate called "localhost".
4.) Import Certificate to Chrome:
Chrome Settings --> Manage Certificates --> Import .pfx certificate from C:\certificates\ folder
Test Certificate by opening Chrome and navigating to https://localhost/
Tests
On the Tests
class we will add an @XmlRootElement
annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData
property differs from the default mapping we will use the @XmlElement
annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted
package forum11221136;
import javax.xml.bind.annotation.*;
@XmlRootElement
public class Tests {
TestData testData;
@XmlElement(name="test-data")
public TestData getTestData() {
return testData;
}
public void setTestData(TestData testData) {
this.testData = testData;
}
}
TestData
On this class I used the @XmlType
annotation to specify the order in which the elements should be ordered in. I added a testData
property that appeared to be missing. I also used an @XmlElement
annotation for the same reason as in the Tests
class.
package forum11221136;
import java.util.List;
import javax.xml.bind.annotation.*;
@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
String title;
String book;
String count;
List<TestData> testData;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getBook() {
return book;
}
public void setBook(String book) {
this.book = book;
}
public String getCount() {
return count;
}
public void setCount(String count) {
this.count = count;
}
@XmlElement(name="test-data")
public List<TestData> getTestData() {
return testData;
}
public void setTestData(List<TestData> testData) {
this.testData = testData;
}
}
Demo
Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.
package forum11221136;
import java.io.File;
import javax.xml.bind.*;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(Tests.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
File xml = new File("src/forum11221136/input.xml");
Tests tests = (Tests) unmarshaller.unmarshal(xml);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(tests, System.out);
}
}
No need to include JQuery or any other third party library.
Specify your input date format in title tag.
HTML:
<script type="text/javascript" src="http://services.iperfect.net/js/IP_generalLib.js">
Body
<input type="text" name="date1" id="date1" alt="date" class="IP_calendar" title="d/m/Y">
Below works for first tr
of the table under thead
table thead tr:first-child {
background: #f2f2f2;
}
And this works for the first tr
of thead
and tbody
both:
table thead tbody tr:first-child {
background: #f2f2f2;
}
using(SqlDataReader rdr = cmd.ExecuteReader())
{
while (rdr.Read())
{
var myString = rdr.GetString(0); //The 0 stands for "the 0'th column", so the first column of the result.
// Do somthing with this rows string, for example to put them in to a list
listDeclaredElsewhere.Add(myString);
}
}
If you know the type of image and only want to generate a file, there's no need to get a BufferedImage instance. Just write the bytes to a file with the correct extension.
try (OutputStream out = new BufferedOutputStream(new FileOutputStream(path))) {
out.write(bytes);
}
Now you do not even need to think about the difference between these two because of Spacemacs. It is a community-driven Emacs distribution.
As it said,
The best editor is neither Emacs nor vim, It's Emacs and Vim.
Spacemacs combines the best from both Emacs and Vim, which make your life and job much easier.

I suggest using the official pkg on Mac. I guess docker-compose is no longer included with docker by default: https://docs.docker.com/toolbox/toolbox_install_mac/
Just one note I could not find in the answers above. In this code:
context_instance = RequestContext(request)
return render_to_response(template_name, user_context, context_instance)
What the third parameter context_instance
actually does? Being RequestContext it sets up some basic context which is then added to user_context
. So the template gets this extended context. What variables are added is given by TEMPLATE_CONTEXT_PROCESSORS
in settings.py. For instance django.contrib.auth.context_processors.auth adds variable user
and variable perm
which are then accessible in the template.
for (NSString* key in xyz) {
id value = xyz[key];
// do stuff
}
This works for every class that conforms to the NSFastEnumeration protocol (available on 10.5+ and iOS), though NSDictionary
is one of the few collections which lets you enumerate keys instead of values. I suggest you read about fast enumeration in the Collections Programming Topic.
Oh, I should add however that you should NEVER modify a collection while enumerating through it.
A bit late to the party here but here's how simple this is:
ViewBag.Countries = new SelectList(countries.GetCountries(), "id", "countryName", "82");
this uses my method getcountries to populate a model called countries, obviousley you would replace this with whatever your datasource is, a model etc, then sets the id as the value in the selectlist. then just add the last param, in this case "82" to select the default selected item.
[edit] Here's how to use this in Razor:
@Html.DropDownListFor(model => model.CountryId, (IEnumerable<SelectListItem>)ViewBag.Countries, new { @class = "form-control" })
Important: Also, 1 other thing to watch out for, Make sure the model field that you use to store the selected Id (in this case model.CountryId) from the dropdown list is nullable and is set to null on the first page load. This one gets me every time.
Hope this saves someone some time.
Yes this is possible, however not convenient as Jens said. Using Next generation load balancers like Alteon, which Uses a proprietary protocol called DSSP(Distributed site state Protocol) which performs regular site checks to make sure that the service is available both Locally or Globally i.e different geographical areas. You need to however in your Master DNS to delegate the URL or Service to the device by configuring it as an Authoritative Name Server for that IP or Service. By doing this, the device answers DNS queries where it will resolve the IP that has a service by Round-Robin or is not congested according to how you have chosen from several metrics.
For my case, I follow the steps from Firebase
and by mistake I pated it in a wrong file.
Then, I returned to the project from Project
to Android
. Once in the Android view
I pasted the file /projectname/app/YOUR-FILE-HERE
and now, you have to compile again.
You can put the filenames returned by find
into an array like this:
array=()
while IFS= read -r -d ''; do
array+=("$REPLY")
done < <(find . -name '*.txt' -print0)
Now you can just loop through the array to access individual items and do whatever you want with them.
Note: It's white space safe.

I ran into this problem as well, and figured out that the problem is in the browser. When you refresh the browser is re-populating the form with the same values as before, ignoring the checked field. If you view source, you'll see the checked value is correct. Or put your cursor in your browser's URL field and hit enter. That will re-load the form from scratch.
Mongodb v3.4
You need to do the following to create a secure database:
Make sure the user starting the process has permissions and that the directories exist (/data/db
in this case).
1) Start MongoDB without access control.
mongod --port 27017 --dbpath /data/db
2) Connect to the instance.
mongo --port 27017
3) Create the user administrator (in the admin authentication database).
use admin
db.createUser(
{
user: "myUserAdmin",
pwd: "abc123",
roles: [ { role: "userAdminAnyDatabase", db: "admin" } ]
}
)
4) Re-start the MongoDB instance with access control.
mongod --auth --port 27017 --dbpath /data/db
5) Connect and authenticate as the user administrator.
mongo --port 27017 -u "myUserAdmin" -p "abc123" --authenticationDatabase "admin"
6) Create additional users as needed for your deployment (e.g. in the test authentication database).
use test
db.createUser(
{
user: "myTester",
pwd: "xyz123",
roles: [ { role: "readWrite", db: "test" },
{ role: "read", db: "reporting" } ]
}
)
7) Connect and authenticate as myTester.
mongo --port 27017 -u "myTester" -p "xyz123" --authenticationDatabase "test"
I basically just explained the short version of the official docs here: https://docs.mongodb.com/master/tutorial/enable-authentication/
I think the simplest way is:
<th data-searchable="false">Column</th>
You can edit only the table you have to modify, without change common CSS or JS.
>>> " xyz ".rstrip()
' xyz'
There is more about rstrip
in the documentation.
One other work-around is to use jupyter notebooks and use the markdown mode in cells to render equations.
Basic stuff seems to work perfectly, like centered equations
\begin{equation}
...
\end{equation}
or inline equations
$ \sum_{\forall i}{x_i^{2}} $
Although, one of the functions that I really wanted did not render at all in github was \mbox{}
, which was a bummer. But, all in all this has been the most successful way of rendering equations on github.
The simplest supported solution is to either use margin
.element {
display: block;
margin: 0px auto;
}
Or use a second container around the element that has this margin applied. This will somewhat have the effect of padding: 0px auto
if it did exist.
CSS
.element_wrapper {
display: block;
margin: 0px auto;
}
.element {
background: blue;
}
HTML
<div class="element_wrapper">
<div class="element">
Hello world
</div>
</div>

I'm using tesseract OCR engine with TessNet2 (a C# wrapper - http://www.pixel-technology.com/freeware/tessnet2/).
Some basic code:
using tessnet2;
...
Bitmap image = new Bitmap(@"u:\user files\bwalker\2849257.tif");
tessnet2.Tesseract ocr = new tessnet2.Tesseract();
ocr.SetVariable("tessedit_char_whitelist", "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.,$-/#&=()\"':?"); // Accepted characters
ocr.Init(@"C:\Users\bwalker\Documents\Visual Studio 2010\Projects\tessnetWinForms\tessnetWinForms\bin\Release\", "eng", false); // Directory of your tessdata folder
List<tessnet2.Word> result = ocr.DoOCR(image, System.Drawing.Rectangle.Empty);
string Results = "";
foreach (tessnet2.Word word in result)
{
Results += word.Confidence + ", " + word.Text + ", " + word.Left + ", " + word.Top + ", " + word.Bottom + ", " + word.Right + "\n";
}
This code snippet can be used for displaying time in seconds,milliseconds and microseconds:
#include <sys/time.h>
struct timeval start, stop;
double secs = 0;
gettimeofday(&start, NULL);
// Do stuff here
gettimeofday(&stop, NULL);
secs = (double)(stop.tv_usec - start.tv_usec) / 1000000 + (double)(stop.tv_sec - start.tv_sec);
printf("time taken %f\n",secs);
You can use after of you method map()
. The method filter()
for example in your case:
var sources = images.map(function (img) {
if(img.src.split('.').pop() === "json"){ // if extension is .json
return null; // skip
}
else {
return img.src;
}
});
The method filter:
const sourceFiltered = sources.filter(item => item)
Then, only the existing items are in the new array sourceFiltered
.
I believe the issue at hand is that is the statement was skipped, and you tried to use the var elsewhere, it wouldn't be declared.

This is a BAD way to do it! I'm only leaving this answer in case it solves other weird problems. These better methods are the probably partly the result of newer data.table versions... so it's worth while to document this hard way. Plus, this is a nice syntax example for eval
substitute
syntax.
library(data.table)
dt <- data.table(ID = c(rep("A", 5), rep("B",5)),
fac1 = c(1:5, 1:5),
fac2 = c(1:5, 1:5) * 2,
val1 = rnorm(10),
val2 = rnorm(10))
names_factors = c('fac1', 'fac2')
names_values = c('val1', 'val2')
for (col in names_factors){
e = substitute(X := as.factor(X), list(X = as.symbol(col)))
dt[ , eval(e)]
}
for (col in names_values){
e = substitute(X := as.numeric(X), list(X = as.symbol(col)))
dt[ , eval(e)]
}
str(dt)
which gives you
Classes ‘data.table’ and 'data.frame': 10 obs. of 5 variables:
$ ID : chr "A" "A" "A" "A" ...
$ fac1: Factor w/ 5 levels "1","2","3","4",..: 1 2 3 4 5 1 2 3 4 5
$ fac2: Factor w/ 5 levels "2","4","6","8",..: 1 2 3 4 5 1 2 3 4 5

At this time, the most authoritative answer appears to be in this issue, which states "it is a custom build of jQuery that excludes effects, ajax, and deprecated code." Details will be announced with jQuery 3.0.
I suspect that the rationale for excluding these components of the jQuery library is in recognition of the increasingly common scenario of jQuery being used in conjunction with another JS framework like Angular or React. In these cases, the usage of jQuery is primarily for DOM traversal and manipulation, so leaving out those components that are either obsolete or are provided by the framework gains about a 20% reduction in file size.
You have a column InvoiceID
in the Invoices
table and also in the InvoiceLineItems
table. There is no way for the query execution engine to know which one you want returned.
Adding a table alias will help:
SELECT V.VendorName, I.InvoiceID, IL.InvoiceSequence, IL.InvoiceLineItemAmount
FROM Vendors V
JOIN Invoices I ON (...)
JOIN InvoiceLineItems IL ON (...)
WHERE ...
ORDER BY V.VendorName, I.InvoiceID, IL.InvoiceSequence, IL.InvoiceLineItemAmount
And for webkit enabled browsers I've had good results with:
.myElement {
-webkit-overflow-scrolling: touch;
scroll-behavior: smooth; // Added in from answer from Felix
overflow-x: scroll;
}
This makes scrolling behave much more like the standard browser behavior - at least it works well on the iPhone we were testing on!
Hope that helps,

you can use show
instead of shown
for making the function to load just before modal open, instead of after modal open.
$('#code').on('show.bs.modal', function (e) {
// do something...
})
From within your batch file:
%cd%
refers to the current working directory (variable)%~dp0
refers to the full path to the batch file's directory (static)%~dpnx0
and %~f0
both refer to the full path to the batch directory and file name (static).A very simple solution is to override
the toString()
method in the Node
. Then, you can call print by passing LinkedList
's head
.
You don't need to implement any kind of loop.
Code:
public class LinkedListNode {
...
//New
@Override
public String toString() {
return String.format("Node(%d, next = %s)", data, next);
}
}
public class LinkedList {
public static void main(String[] args) {

The template it is referring to is the Html helper DisplayFor
.
DisplayFor expects to be given an expression that conforms to the rules as specified in the error message.
You are trying to pass in a method chain to be executed and it doesn't like it.
This is a perfect example of where the MVVM (Model-View-ViewModel) pattern comes in handy.
You could wrap up your Trainer
model class in another class called TrainerViewModel
that could work something like this:
class TrainerViewModel
{
private Trainer _trainer;
public string ShortDescription
{
get
{
return _trainer.Description.ToString().Substring(0, 100);
}
}
public TrainerViewModel(Trainer trainer)
{
_trainer = trainer;
}
}
You would modify your view model class to contain all the properties needed to display that data in the view, hence the name ViewModel.
Then you would modify your controller to return a TrainerViewModel
object rather than a Trainer
object and change your model type declaration in your view file to TrainerViewModel
too.
If the method accepts non-primitive data type then the following method can be used to invoke a private method of any class:
public static Object genericInvokeMethod(Object obj, String methodName,
Object... params) {
int paramCount = params.length;
Method method;
Object requiredObj = null;
Class<?>[] classArray = new Class<?>[paramCount];
for (int i = 0; i < paramCount; i++) {
classArray[i] = params[i].getClass();
}
try {
method = obj.getClass().getDeclaredMethod(methodName, classArray);
method.setAccessible(true);
requiredObj = method.invoke(obj, params);
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
return requiredObj;
}
The Parameter accepted are obj, methodName and the parameters. For example
public class Test {
private String concatString(String a, String b) {
return (a+b);
}
}
Method concatString can be invoked as
Test t = new Test();
String str = (String) genericInvokeMethod(t, "concatString", "Hello", "Mr.x");
Just You have to restore packages to solve this issue, So just run command :
npm install or yarn install
without linq,
use Sort()
and then Reverse()
it.
What you put inside the </dependencies>
tag of the root pom will be included by all child modules of the root pom. If all your modules use that dependency, this is the way to go.
However, if only 3 out of 10 of your child modules use some dependency, you do not want this dependency to be included in all your child modules. In that case, you can just put the dependency inside the </dependencyManagement>
. This will make sure that any child module that needs the dependency must declare it in their own pom file, but they will use the same version of that dependency as specified in your </dependencyManagement>
tag.
You can also use the </dependencyManagement>
to modify the version used in transitive dependencies, because the version declared in the upper most pom file is the one that will be used. This can be useful if your project A includes an external project B v1.0 that includes another external project C v1.0. Sometimes it happens that a security breach is found in project C v1.0 which is corrected in v1.1, but the developers of B are slow to update their project to use v1.1 of C. In that case, you can simply declare a dependency on C v1.1 in your project's root pom inside `, and everything will be good (assuming that B v1.0 will still be able to compile with C v1.1).
WARNING: contains sarcasm judiciously! YMMV...
Luigi's answer is complete and correct. This one is only to extend it a bit with an example of how you can gloriously overuse implicits, as it happens quite often in Scala projects. Actually so often, you can probably even find it in one of the "Best Practice" guides.
object HelloWorld {
case class Text(content: String)
case class Prefix(text: String)
implicit def String2Text(content: String)(implicit prefix: Prefix) = {
Text(prefix.text + " " + content)
}
def printText(text: Text): Unit = {
println(text.content)
}
def main(args: Array[String]): Unit = {
printText("World!")
}
// Best to hide this line somewhere below a pile of completely unrelated code.
// Better yet, import its package from another distant place.
implicit val prefixLOL = Prefix("Hello")
}
You probably need to install it using one of (or something similar to) the following:
sudo apt-get install python3-tk
You can also mention version number like this
sudo apt-get install python3.7-tk
for python 3.7.
sudo dnf install python3-tkinter
Why don't you try this and let me know if it worked:
try:
# for Python2
from Tkinter import * ## notice capitalized T in Tkinter
except ImportError:
# for Python3
from tkinter import * ## notice lowercase 't' in tkinter here
Here is the reference link and here are the docs
Better to check versions as suggested here:
if sys.version_info[0] == 3:
# for Python3
from tkinter import * ## notice lowercase 't' in tkinter here
else:
# for Python2
from Tkinter import * ## notice capitalized T in Tkinter
Or you will get an error ImportError: No module named tkinter
Just to make this answer more generic I borrowed the following from Devendra Bhat's comment:
On Fedora please use either of the following commands
sudo dnf install python3-tkinter-3.6.6-1.fc28.x86_64
or
sudo dnf install python3-tkinter
This is a variation of the anwser by Muhammad Rehan Saeed, with the class getting parasitically attached to the existing .net core MVC class of the same name, so that everything just works.

The RSACryptoServiceProvider(CspParameters)
constructor creates a keypair which is stored in the keystore on the local machine. If you already have a keypair with the specified name, it uses the existing keypair.
It sounds as if you are not interested in having the key stored on the machine.
So use the RSACryptoServiceProvider(Int32)
constructor:
public static void AssignNewKey(){
RSA rsa = new RSACryptoServiceProvider(2048); // Generate a new 2048 bit RSA key
string publicPrivateKeyXML = rsa.ToXmlString(true);
string publicOnlyKeyXML = rsa.ToXmlString(false);
// do stuff with keys...
}
EDIT:
Alternatively try setting the PersistKeyInCsp to false:
public static void AssignNewKey(){
const int PROVIDER_RSA_FULL = 1;
const string CONTAINER_NAME = "KeyContainer";
CspParameters cspParams;
cspParams = new CspParameters(PROVIDER_RSA_FULL);
cspParams.KeyContainerName = CONTAINER_NAME;
cspParams.Flags = CspProviderFlags.UseMachineKeyStore;
cspParams.ProviderName = "Microsoft Strong Cryptographic Provider";
rsa = new RSACryptoServiceProvider(cspParams);
rsa.PersistKeyInCsp = false;
string publicPrivateKeyXML = rsa.ToXmlString(true);
string publicOnlyKeyXML = rsa.ToXmlString(false);
// do stuff with keys...
}
When you do the for/in loop you put up first, i is the property name. So you have the property name, i, and access the value by doing myObject[i].
ActiveX resolved in Chrome!
Hello all this is not the solution but the successful workaround and I have implemented as well.
This required some implementation on client machine as well that why is most suitable for intranet environment and not recommended for public sites. Even though one can implement it for public sites as well the only problem is end user has to download/implement solution.
Lets understand the key problem
Chrome cannot communicate with ActiceX
Solution: Since Chorme cannot communicate with ActiveX but still it can communicate with the API hosted on the client machine. So develop API using .Net MVC or any other technology so that through Ajax call it can communicate with the API and API communicate with the ActiveX object situated on the client machine. Since API also resides in Client machine that why there is no problem in communication. This API works as mediator between Chrome browser and ActiveX.
During API implementation you might encounter CORS issues, Use JSONP to deal with it.
Pictorial view of the solution
Other solution : Use URI Scheme like MailTo: or MS-Word to deal with outlook and word application. If your requirement is different then you can implement your customized URI Scheme.

CASE WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%'
THEN 'BP Medication' ELSE '' END AS [BP Medication]
The leading ', '
and trailing ','
are added so that you can handle the match regardless of where it is in the string (first entry, last entry, or anywhere in between).
That said, why are you storing data you want to search on as a comma-separated string? This violates all kinds of forms and best practices. You should consider normalizing your schema.
In addition: don't use 'single quotes'
as identifier delimiters; this syntax is deprecated. Use [square brackets]
(preferred) or "double quotes"
if you must. See "string literals as column aliases" here: http://msdn.microsoft.com/en-us/library/bb510662%28SQL.100%29.aspx
EDIT If you have multiple values, you can do this (you can't short-hand this with the other CASE
syntax variant or by using something like IN()
):
CASE
WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%'
WHEN ', ' + dbo.Table.Column +',' LIKE '%, amlodipine,%'
THEN 'BP Medication' ELSE '' END AS [BP Medication]
If you have more values, it might be worthwhile to use a split function, e.g.
USE tempdb;
GO
CREATE FUNCTION dbo.SplitStrings(@List NVARCHAR(MAX))
RETURNS TABLE
AS
RETURN ( SELECT DISTINCT Item FROM
( SELECT Item = x.i.value('(./text())[1]', 'nvarchar(max)')
FROM ( SELECT [XML] = CONVERT(XML, '<i>'
+ REPLACE(@List,',', '</i><i>') + '</i>').query('.')
) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
WHERE Item IS NOT NULL
);
GO
CREATE TABLE dbo.[Table](ID INT, [Column] VARCHAR(255));
GO
INSERT dbo.[Table] VALUES
(1,'lactulose, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(2,'lactulite, Lasix (furosemide), lactulose, propranolol, rabeprazole, sertraline,'),
(3,'lactulite, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(4,'lactulite, Lasix (furosemide), lactulose, amlodipine, rabeprazole, sertraline,');
SELECT t.ID
FROM dbo.[Table] AS t
INNER JOIN dbo.SplitStrings('lactulose,amlodipine') AS s
ON ', ' + t.[Column] + ',' LIKE '%, ' + s.Item + ',%'
GROUP BY t.ID;
GO
Results:

If I understood your question, try something like this
declare @dd varchar(50)='Jan 30 2013 12:00:00:000AM'
Select convert(varchar,(CONVERT(date,@dd,103)),103)
Update
SELECT
PREFIX_TableName.ColumnName1 AS Name,
PREFIX_TableName.ColumnName2 AS E-Mail,
convert(varchar,(CONVERT(date,PREFIX_TableName.ColumnName3,103)),103) AS TransactionDate,
PREFIX_TableName.ColumnName4 AS OrderNumber
The Meyers singleton pattern works well enough most of the time, and on the occasions it does it doesn't necessarily pay to look for anything better. As long as the constructor will never throw and there are no dependencies between singletons.
A singleton is an implementation for a globally-accessible object (GAO from now on) although not all GAOs are singletons.
Loggers themselves should not be singletons but the means to log should ideally be globally-accessible, to decouple where the log message is being generated from where or how it gets logged.
Lazy-loading / lazy evaluation is a different concept and singleton usually implements that too. It comes with a lot of its own issues, in particular thread-safety and issues if it fails with exceptions such that what seemed like a good idea at the time turns out to be not so great after all. (A bit like COW implementation in strings).
With that in mind, GOAs can be initialised like this:
namespace {
T1 * pt1 = NULL;
T2 * pt2 = NULL;
T3 * pt3 = NULL;
T4 * pt4 = NULL;
}
int main( int argc, char* argv[])
{
T1 t1(args1);
T2 t2(args2);
T3 t3(args3);
T4 t4(args4);
pt1 = &t1;
pt2 = &t2;
pt3 = &t3;
pt4 = &t4;
dostuff();
}
T1& getT1()
{
return *pt1;
}
T2& getT2()
{
return *pt2;
}
T3& getT3()
{
return *pt3;
}
T4& getT4()
{
return *pt4;
}
It does not need to be done as crudely as that, and clearly in a loaded library that contains objects you probably want some other mechanism to manage their lifetime. (Put them in an object that you get when you load the library).
As for when I use singletons? I used them for 2 things - A singleton table that indicates what libraries have been loaded with dlopen - A message handler that loggers can subscribe to and that you can send messages to. Required specifically for signal handlers.
I'm not sure what you're looking for exactly, but you really should check out these excellent blog posts written by Chris Coyier from CSS-Tricks:
http://css-tricks.com/how-to-resizeable-background-image/
http://css-tricks.com/perfect-full-page-background-image/
Read the descriptions for each of the articles and see if they're what you're looking for.
The first answers the following question:
Is there a way to make a background image resizeable? As in, fill the background of a web page edge-to-edge with an image, no matter the size of the browser window. Also, have it resize larger or smaller as the browser window changes. Also, make sure it retains its ratio (doesn't stretch weird). Also, doesn't cause scrollbars, just cuts off vertically if it needs to. Also, comes in on the page as an inline tag.
The second post's goal is to get the following, a "background image on a website that covers the entire browser window at all times. "
Hope this helps.
var oldString = "stackoverflow";
var str=oldString.replace(/stackover/g,"NO");
$scope.newString= str;
It works for me. Use an intermediate variable.
The easiest solution working fine for me is this:
export CFLAGS=-ggdb
export CXXFLAGS=-ggdb
CMake will append them to all configurations' flags. Just make sure to clear CMake cache.
There also exists a UNIQUE KEY. The main difference between PRIMARY KEY and UNIQUE KEY is that the PRIMARY KEY never takes NULL value while a UNIQUE KEY may take NULL value. Also, there can be only one PRIMARY KEY in a table while UNIQUE KEY may be more than one.
As I don't see here similar approach, and I'm not enjoying setting h/m/s/ms to 0, as it can cause problems with accurate transition to local time zone with changed date
object (I presume so), let me introduce here this, written few moments ago, lil function:
+
: Easy to use, makes a basic comparison operations done (comparing day, month and year without time.)
-
: It seems that this is a complete opposite of "out of the box" thinking.
function datecompare(date1, sign, date2) {
var day1 = date1.getDate();
var mon1 = date1.getMonth();
var year1 = date1.getFullYear();
var day2 = date2.getDate();
var mon2 = date2.getMonth();
var year2 = date2.getFullYear();
if (sign === '===') {
if (day1 === day2 && mon1 === mon2 && year1 === year2) return true;
else return false;
}
else if (sign === '>') {
if (year1 > year2) return true;
else if (year1 === year2 && mon1 > mon2) return true;
else if (year1 === year2 && mon1 === mon2 && day1 > day2) return true;
else return false;
}
}
Usage:
datecompare(date1, '===', date2)
for equality check,
datecompare(date1, '>', date2)
for greater check,
!datecompare(date1, '>', date2)
for less or equal check
Also, obviously, you can switch date1
and date2
in places to achieve any other simple comparison.
abs()
:
Returns the absolute value as per the argument i.e. if argument is int then it returns int, if argument is float it returns float.
Also it works on complex variable also i.e. abs(a+bj)
also works and returns absolute value i.e.math.sqrt(((a)**2)+((b)**2)
math.fabs()
:
It only works on the integer or float values. Always returns the absolute float value no matter what is the argument type(except for the complex numbers).
I had problems installing the 64-bit version of MySQLdb on Windows via Pip (problem compiling sources) [32bit version installed ok]. Managed to install the compiled MySQLdb from the .whl file available from http://www.lfd.uci.edu/~gohlke/pythonlibs/
The .whl file can then be installed via pip as document in https://pip.pypa.io/en/latest/user_guide/#installing-from-wheels
For example if you save in C:/
the you can install via
pip install c:/MySQL_python-1.2.5-cp27-none-win_amd64.whl
Follow-up: if you have a 64bit version of Python installed, then you want to install the 64-bit AMD version of MySQLdb from the link above [i.e. even if you have a Intel processor]. If you instead try and install the 32-bit version, I think you get the unsupported wheel error in comments below.
it is because of using web address, You can not use http to write data. don't use : http:// or https:// in your location for upload files or save data or somting like that. instead of of using $_SERVER["HTTP_REFERER"] use $_SERVER["DOCUMENT_ROOT"]. for example :
wrong :
move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["HTTP_REFERER"].'/uploads/images/1.jpg')
correct:
move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["DOCUMENT_ROOT"].'/uploads/images/1.jpg')
If you have to run composer with sudo, you should change the directory of composer to

I've been struggling with Dialog animation today, finally got it working using styles, so here is an example.
To start with, the most important thing — I probably had it working 5 different ways today but couldn't tell because... If your devices animation settings are set to "No Animations" (Settings ? Display ? Animation) then the dialogs won't be animated no matter what you do!
The following is a stripped down version of my styles.xml. Hopefully it is self-explanatory. This should be located in res/values
.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="PauseDialog" parent="@android:style/Theme.Dialog">
<item name="android:windowAnimationStyle">@style/PauseDialogAnimation</item>
</style>
<style name="PauseDialogAnimation">
<item name="android:windowEnterAnimation">@anim/spin_in</item>
<item name="android:windowExitAnimation">@android:anim/slide_out_right</item>
</style>
</resources>
The windowEnterAnimation
is one of my animations and is located in res\anim
.
The windowExitAnimation
is one of the animations that is part of the Android SDK.
Then when I create the Dialog in my activities onCreateDialog(int id)
method I do the following.
Dialog dialog = new Dialog(this, R.style.PauseDialog);
// Setting the title and layout for the dialog
dialog.setTitle(R.string.pause_menu_label);
dialog.setContentView(R.layout.pause_menu);
Alternatively you could set the animations the following way instead of using the Dialog constructor that takes a theme.
Dialog dialog = new Dialog(this);
dialog.getWindow().getAttributes().windowAnimations = R.style.PauseDialogAnimation;
By an "anonymous class", I take it you mean anonymous inner class.
An anonymous inner class can come useful when making an instance of an object with certain "extras" such as overriding methods, without having to actually subclass a class.
I tend to use it as a shortcut for attaching an event listener:
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
// do something
}
});
Using this method makes coding a little bit quicker, as I don't need to make an extra class that implements ActionListener
-- I can just instantiate an anonymous inner class without actually making a separate class.
I only use this technique for "quick and dirty" tasks where making an entire class feels unnecessary. Having multiple anonymous inner classes that do exactly the same thing should be refactored to an actual class, be it an inner class or a separate class.
The best option is create a directive and wrap the slider features there. The secret is use $timeout, the jquery code will be called only when DOM is ready.
angular.module('app')
.directive('my-slider',
['$timeout', function($timeout) {
return {
restrict:'E',
scope: true,
template: '<div id="{{ id }}"></div>',
link: function($scope) {
$scope.id = String(Math.random()).substr(2, 8);
$timeout(function() {
angular.element('#'+$scope.id).slider();
});
}
};
}]
);
Add the following code to your view controller:
if ([self respondsToSelector:@selector(setNeedsStatusBarAppearanceUpdate)]) {
// iOS 7
[self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
} else {
// iOS 6
[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationSlide];
}
- (BOOL)prefersStatusBarHidden {
return YES;
}
From the Project Explorer, expand the project you want to hook up to a remote site (or just right click and create a new Web project that's empty if you just want to explore a remote site from there). There's a "Connections" node, right click it and select "Add New connection...". A dialog will appear, at bottom you can select the destination as Remote and then click the "New..." button. There you can set up an FTP/FTPS/SFTP connection.
That's how you set up a connection that's tied to a project, typically for upload/download/sync between it and a project.
You can also do Window > Show View > Remote. From that view, you can click the globe icon in the upper right to add connections and in this view you can just browse your remote connections.
C# in .NET 3.5 using System.DirectoryServices.AccountManagement.
bool valid = false;
using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
valid = context.ValidateCredentials( username, password );
}
This will validate against the current domain. Check out the parameterized PrincipalContext constructor for other options.
You can also use DB::unprepared
for ALTER TABLE
queries.
DB::unprepared
is meant to be used for queries like CREATE TRIGGER
. But essentially it executes raw sql queries directly. (without using PDO prepared
statements)
Create another class which contains your strongly typed class.
Add your new stuff to the class and return it in the view.
Then in the view, ensure you inherit your new class and change the bits of code that will now be in error. namely the references to your fields.
Hope this helps. If not then let me know and I'll post specific code.
You can also try to check null before delete such that
if(myArray) { delete[] myArray; myArray = NULL; }
or you can define all delete operations ina safe manner like this:
#ifndef SAFE_DELETE
#define SAFE_DELETE(p) { if(p) { delete (p); (p) = NULL; } }
#endif
#ifndef SAFE_DELETE_ARRAY
#define SAFE_DELETE_ARRAY(p) { if(p) { delete[] (p); (p) = NULL; } }
#endif
and then use
SAFE_DELETE_ARRAY(myArray);
This is how you can nest multiple bool queries in one outer bool query this using Kibana,
GET my_inedx/my_type/_search
{
"query" : {
"bool": { //bool indicates we are using boolean operator
"must" : [ //must is for **AND**
{
"match" : {
"description" : "some text"
}
},
{
"match" :{
"type" : "some Type"
}
},
{
"bool" : { //here its a nested boolean query
"should" : [ //should is for **OR**
{
"match" : {
//ur query
}
},
{
"match" : {}
}
]
}
}
]
}
}
}
This is how you can nest a query in ES
There are more types in "bool" like,
All cookies are client and server
There is no difference. A regular cookie can be set server side or client side. The 'classic' cookie will be sent back with each request. A cookie that is set by the server, will be sent to the client in a response. The server only sends the cookie when it is explicitly set or changed, while the client sends the cookie on each request.
But essentially it's the same cookie.
But, behavior can change
A cookie is basically a name=value
pair, but after the value can be a bunch of semi-colon separated attributes that affect the behavior of the cookie if it is so implemented by the client (or server).
Those attributes can be about lifetime, context and various security settings.
HTTP-only (is not server-only)
One of those attributes can be set by a server to indicate that it's an HTTP-only cookie. This means that the cookie is still sent back and forth, but it won't be available in JavaScript. Do note, though, that the cookie is still there! It's only a built in protection in the browser, but if somebody would use a ridiculously old browser like IE5, or some custom client, they can actually read the cookie!
So it seems like there are 'server cookies', but there are actually not. Those cookies are still sent to the client. On the client there is no way to prevent a cookie from being sent to the server.
Alternatives to achieve 'only-ness'
If you want to store a value only on the server, or only on the client, then you'd need some other kind of storage, like a file or database on the server, or Local Storage on the client.
In my opinion, it would be a cleaner and easier solution to just set a class on the body and set the font-family in css according to that class.
don't know if that's an option in your case though.
I added the DOCTYPE
directive you see here:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [
<!ENTITY nl "
">
]>
<xsl:stylesheet xmlns:x="http://www.w3.org/2005/02/query-test-XQTSCatalog"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
This allows me to use &nl;
instead of 

to produce a newline in the output. Like other solutions, this is typically placed inside a <xsl:text>
tag.
I think there's cleaner way where you don't have to create a new webclient (and it'll work with 3rd party libraries as well)
internal static class MyWebRequestCreator
{
private static IWebRequestCreate myCreator;
public static IWebRequestCreate MyHttp
{
get
{
if (myCreator == null)
{
myCreator = new MyHttpRequestCreator();
}
return myCreator;
}
}
private class MyHttpRequestCreator : IWebRequestCreate
{
public WebRequest Create(Uri uri)
{
var req = System.Net.WebRequest.CreateHttp(uri);
req.CookieContainer = new CookieContainer();
return req;
}
}
}
Now all you have to do is opt in for which domains you want to use this:
WebRequest.RegisterPrefix("http://example.com/", MyWebRequestCreator.MyHttp);
That means ANY webrequest that goes to example.com will now use your custom webrequest creator, including the standard webclient. This approach means you don't have to touch all you code. You just call the register prefix once and be done with it. You can also register for "http" prefix to opt in for everything everywhere.
Try promise-abortable: https://www.npmjs.com/package/promise-abortable
$ npm install promise-abortable
import AbortablePromise from "promise-abortable";
const timeout = new AbortablePromise((resolve, reject, signal) => {
setTimeout(reject, timeToLive, error);
signal.onabort = resolve;
});
Promise.resolve(fn()).then(() => {
timeout.abort();
});
The string is a .NET string so you can use .NET methods. In your case:
$index = "The string".IndexOf(" ")
will return 3, which is the first occurrence of space in the string. For more information see: http://msdn.microsoft.com/en-us/library/system.string.aspx
For your need try something like:
$s.SubString($s.IndexOf("_") + 1, $s.LastIndexOf(".") - $s.IndexOf("_") - 1)
Or you could use regexps:
if ($s -Match '(_)(.*)(\.)[^.]*$') { $matches[2] }
(has to be adjusted depending on exactly what you need).
for a non-nested dict (since the title does not mention that case, it might be interesting for other people)
{str(k): str(v) for k, v in my_dict.items()}
Off topic, this can be done using the grep also, just posting it here in case if anyone is looking for grep solution
echo 'xxx yyy zzze ' | grep -oE 'yyy'
I also had this problem when doing migration => after performing php artisan migrate:refresh --seed command
"Base table or view not found: 1146 Table posts do not exist" and I solved it, I was using "soft deletes" in a separate migration file, and my original migration for "posts" table which was responsible for creating the "posts" table was performing after the "soft deletes" migration in the database\migration folder, I simply needed to rename the "posts" migration file name and put it before "softdeletes" migration to perform sooner. the do the migration again => php artisan migrate:refresh --seed it's done.
It looks like body-parser
did support uploading files in Express 3, but support was dropped for Express 4 when it no longer included Connect as a dependency
After looking through some of the modules in mscdex's answer, I found that express-busboy
was a far better alternative and the closest thing to a drop-in replacement. The only differences I noticed were in the properties of the uploaded file.
console.log(req.files)
using body-parser (Express 3) output an object that looked like this:
{ file:
{ fieldName: 'file',
originalFilename: '360px-Cute_Monkey_cropped.jpg',
name: '360px-Cute_Monkey_cropped.jpg'
path: 'uploads/6323-16v7rc.jpg',
type: 'image/jpeg',
headers:
{ 'content-disposition': 'form-data; name="file"; filename="360px-Cute_Monkey_cropped.jpg"',
'content-type': 'image/jpeg' },
ws:
WriteStream { /* ... */ },
size: 48614 } }
compared to console.log(req.files)
using express-busboy (Express 4):
{ file:
{ field: 'file',
filename: '360px-Cute_Monkey_cropped.jpg',
file: 'uploads/9749a8b6-f9cc-40a9-86f1-337a46e16e44/file/360px-Cute_Monkey_cropped.jpg',

when you render
a request tou coctext
some information:
for exampel:
return render(request, 'path to template',{'username' :username , 'email'.email})
you can acces to it on template like this :
for variabels :
{% if username %}{{ username }}{% endif %}
for array :
{% if username %}{{ username.1 }}{% endif %}
{% if username %}{{ username.2 }}{% endif %}
you can also name array objects in views.py
and ten use it like:
{% if username %}{{ username.first }}{% endif %}

Make sure the database tables are using InnoDB storage engine and READ-COMMITTED transaction isolation level.
You can check it by SELECT @@GLOBAL.tx_isolation, @@tx_isolation; on mysql console.
If it is not set to be READ-COMMITTED then you must set it. Make sure before setting it that you have SUPER privileges in mysql.
You can take help from http://dev.mysql.com/doc/refman/5.0/en/set-transaction.html.
By setting this I think your problem will be get solved.
You might also want to check you aren't attempting to update this in two processes at once. Users ( @tala ) have encountered similar error messages in this context, maybe double-check that...

You have two easy ways to do this. Jay has covered the accurate way of checking from the center of the ball.
The easier way is to use a rectangle bounding box, set the size of your box to be 80% the size of the ball, and you'll simulate collision pretty well.
Add a method to your ball class:
public Rectangle getBoundingRect()
{
int ballHeight = (int)Ball.Height * 0.80f;
int ballWidth = (int)Ball.Width * 0.80f;
int x = Ball.X - ballWidth / 2;
int y = Ball.Y - ballHeight / 2;
return new Rectangle(x,y,ballHeight,ballWidth);
}
Then, in your loop:
// Checks every ball against every other ball.
// For best results, split it into quadrants like Ryan suggested.
// I didn't do that for simplicity here.
for (int i = 0; i < balls.count; i++)
{
Rectangle r1 = balls[i].getBoundingRect();
for (int k = 0; k < balls.count; k++)
{
if (balls[i] != balls[k])
{
Rectangle r2 = balls[k].getBoundingRect();
if (r1.Intersects(r2))
{
// balls[i] collided with balls[k]
}
}
}
}
Regarding the first (and great) answer from chris who proposed a solution to the situation where the class members are held as a "true composite" members (i.e.- not as pointers nor references):
The note is a bit large, so I will demonstrate it here with some sample code.
When you chose to hold the members as I mentioned, you have to keep in mind also these two things:
For every "composed object" that does not have a default constructor - you must initialize it in the initialization list of all the constructor's of the "father" class (i.e.- BigMommaClass
or MyClass
in the original examples and MyClass
in the code below), in case there are several (see InnerClass1
in the example below). Meaning, you can "comment out" the m_innerClass1(a)
and m_innerClass1(15)
only if you enable the InnerClass1
default constructor.
For every "composed object" that does have a default constructor - you may initialize it within the initialization list, but it will work also if you chose not to (see InnerClass2
in the example below).
See sample code (compiled under Ubuntu 18.04 (Bionic Beaver) with g++
version 7.3.0):
#include <iostream>
using namespace std;
class InnerClass1
{
public:
InnerClass1(int a) : m_a(a)
{
cout << "InnerClass1::InnerClass1 - set m_a:" << m_a << endl;
}
/* No default constructor
InnerClass1() : m_a(15)
{
cout << "InnerClass1::InnerClass1() - set m_a:" << m_a << endl;
}
*/
~InnerClass1()
{
cout << "InnerClass1::~InnerClass1" << endl;
}
private:
int m_a;
};
class InnerClass2
{
public:
InnerClass2(int a) : m_a(a)
{
cout << "InnerClass2::InnerClass2 - set m_a:" << m_a << endl;
}
InnerClass2() : m_a(15)
{
cout << "InnerClass2::InnerClass2() - set m_a:" << m_a << endl;
}
~InnerClass2()
{
cout << "InnerClass2::~InnerClass2" << endl;
}
private:
int m_a;
};
class MyClass
{
public:
MyClass(int a, int b) : m_innerClass1(a), /* m_innerClass2(a),*/ m_b(b)
{
cout << "MyClass::MyClass(int b) - set m_b to:" << m_b << endl;
}
MyClass() : m_innerClass1(15), /*m_innerClass2(15),*/ m_b(17)
{
cout << "MyClass::MyClass() - m_b:" << m_b << endl;
}
~MyClass()
{
cout << "MyClass::~MyClass" << endl;
}
private:
InnerClass1 m_innerClass1;
InnerClass2 m_innerClass2;
int m_b;
};

{
cout << "main - start" << endl;

phpPgAdmin is PostgreSQL web frontend which is quite good.
When you are creating an object of intent, you can take advantage of following two methods for passing objects between two activities.
You can have your class implement either Parcelable or Serializable. Then you can pass around your custom classes across activities. I have found this very useful.
Here is a small snippet of code I am using
CustomListing currentListing = new CustomListing();
Intent i = new Intent();
Bundle b = new Bundle();
b.putParcelable(Constants.CUSTOM_LISTING, currentListing);
i.putExtras(b);
i.setClass(this, SearchDetailsActivity.class);
startActivity(i);
And in newly started activity code will be something like this...
Bundle b = this.getIntent().getExtras();
if (b != null)
mCurrentListing = b.getParcelable(Constants.CUSTOM_LISTING);
This is a refined and better performing variant:
String.prototype.hashCode = function() {
var hash = 0, i = 0, len = this.length;
while ( i < len ) {
hash = ((hash << 5) - hash + this.charCodeAt(i++)) << 0;
}
return hash;
};
This matches Java's implementation of the standard object.hashCode()
Here is also one that returns only positive hashcodes:
String.prototype.hashcode = function() {
return (this.hashCode() + 2147483647) + 1;
};
And here is a matching one for Java that only returns positive hashcodes:
public static long hashcode(Object obj) {
return ((long) obj.hashCode()) + Integer.MAX_VALUE + 1l;
}
Enjoy!
Without prototype:
function hashCode(str) {
var hash = 0, i = 0, len = str.length;
while ( i < len ) {
hash = ((hash << 5) - hash + str.charCodeAt(i++)) << 0;
}
return hash;
}
In case anyone "bumps" in this SO question in search for strategies for Informix table when PK is type Serial.
I have found that this works...as an example.
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name = "special_serial_pk")
private Integer special_serial_pk;
For this to work make sure when you do session.SaveOrUpdate you pass the value for the column special_serial_pk NULL .
In my case i do an HTML POST with JSON like so...
{
"special_serial_pk": null, //<-- Field to be incremented
"specialcolumn1": 1,
"specialcolumn2": "I love to code",
"specialcolumn3": true
}
There is another way without using $watch, using angular.copy:
var myApp = angular.module('myApp', []);
myApp.factory('Data', function(){
var service = {
FirstName: '',
setFirstName: function(name) {
// this is the trick to sync the data
// so no need for a $watch function
// call this from anywhere when you need to update FirstName
angular.copy(name, service.FirstName);
}
};
return service;
});
// Step 1 Controller
myApp.controller('FirstCtrl', function( $scope, Data ){
});
// Step 2 Controller
myApp.controller('SecondCtrl', function( $scope, Data ){
$scope.FirstName = Data.FirstName;
});
For Django versions > 1.10, according to the documentation, a custom MIDDLEWARE can be written as a function, let's say in the file: yourproject/middleware.py
(as a sibling of settings.py
):
def open_access_middleware(get_response):
def middleware(request):
response = get_response(request)
response["Access-Control-Allow-Origin"] = "*"
response["Access-Control-Allow-Headers"] = "*"
return response
return middleware
and finally, add the python path of this function (w.r.t. the root of your project) to the MIDDLEWARE list in your project's settings.py
:
MIDDLEWARE = [
.
.
'django.middleware.clickjacking.XFrameOptionsMiddleware',
'yourproject.middleware.open_access_middleware'
]
Easy peasy!

JavaScript has the Array.prototype.some()
method:
[1, 2, 3].some((num) => num % 2 === 0);
returns true
because there's (at least) one even number in the array.
In general, the Array
class in JavaScript's standard library is quite poor compared to Ruby's Enumerable. There's no isEmpty
method and .some()
requires that you pass in a function or you'll get an undefined is not a function
error. You can define your own .isEmpty()
as well as a .any()
that is closer to Ruby's like this:
Array.prototype.isEmpty = function() {
return this.length === 0;
}
Array.prototype.any = function(func) {
return this.some(func || function(x) { return x });
}
Libraries like underscore.js and lodash provide helper methods like these, if you're used to Ruby's collection methods, it might make sense to include them in your project.
Simply you can use $state.transitionTo
instead of $state.go
. $state.go
calls $state.transitionTo
internally but automatically sets options to { location: true, inherit: true, relative: $state.$current, notify: true }
. You can call $state.transitionTo
and set notify: false
. For example:
$state.go('.detail', {id: newId})
can be replaced by
$state.transitionTo('.detail', {id: newId}, {
location: true,
inherit: true,
relative: $state.$current,
notify: false
})
Edit: As suggested by fracz it can simply be:
$state.go('.detail', {id: newId}, {notify: false})
Yep, draw a box and give it a border radius that is half the width of the box:
#circle {
background: #f00;
width: 200px;
height: 200px;
border-radius: 50%;
}
Working demo:
#circle {_x000D_
background: #f00;_x000D_
width: 200px;_x000D_
height: 200px;_x000D_
border-radius: 50%;_x000D_
}
_x000D_
<div id="circle"></div>
_x000D_
You could use the Fisher-Yates Shuffle (code adapted from this site):
function shuffle(array) {
let counter = array.length;
// While there are elements in the array
while (counter > 0) {
// Pick a random index
let index = Math.floor(Math.random() * counter);
// Decrease counter by 1
counter--;
// And swap the last element with it
let temp = array[counter];
array[counter] = array[index];
array[index] = temp;
}
return array;
}
For MyBatis 3.0.4 with Annotations and Postgresql driver 9.0-801.jdbc4 you define an interface method in your Mapper like
public interface ObjectiveMapper {
@Select("insert into objectives" +
" (code,title,description) values" +
" (#{code}, #{title}, #{description}) returning id")
int insert(Objective anObjective);
Note that @Select is used instead of @Insert.
To make a note on Dick's answer, this is correct, but I would not recommend using a For Each loop. For Each creates a temporary reference to the COM Cell behind the scenes that you do not have access to (that you would need in order to dispose of it).
See the following for more discussion:
How do I properly clean up Excel interop objects?
To illustrate the issue, try the For Each example, close your application, and look at Task Manager. You should see that an instance of Excel is still running (because all objects were not disposed of properly).
A cleaner way to handle this is to query the spreadsheet using ADO:
LinkedHashMap will return the elements in the order they were inserted into the map when you iterate over the keySet(), entrySet() or values() of the map.
Map<String, String> map = new LinkedHashMap<String, String>();
map.put("id", "1");
map.put("name", "rohan");
map.put("age", "26");
for (Map.Entry<String, String> entry : map.entrySet()) {
System.out.println(entry.getKey() + " = " + entry.getValue());
}
This will print the elements in the order they were put into the map:
id = 1
name = rohan
age = 26
First, you need to import from inspect
and os
from inspect import getsourcefile
from os.path import abspath
Next, wherever you want to find the source file from you just use
abspath(getsourcefile(lambda:0))
