You could merge two queries together:
$merged = $query_one->merge($query_two);
You need both a value and a field to assign it to. The value is TableField + 1
, so the assignment is:
SET TableField = TableField + 1
You create the relationships the other way around; add foreign keys to the Person
type to create a Many-to-One relationship:
class Person(models.Model):
name = models.CharField(max_length=50)
birthday = models.DateField()
anniversary = models.ForeignKey(
Anniversary, on_delete=models.CASCADE)
address = models.ForeignKey(
Address, on_delete=models.CASCADE)
class Address(models.Model):
line1 = models.CharField(max_length=150)
line2 = models.CharField(max_length=150)
postalcode = models.CharField(max_length=10)
city = models.CharField(max_length=150)
country = models.CharField(max_length=150)
class Anniversary(models.Model):
date = models.DateField()
Any one person can only be connected to one address and one anniversary, but addresses and anniversaries can be referenced from multiple Person
entries.
Anniversary
and Address
objects will be given a reverse, backwards relationship too; by default it'll be called person_set
but you can configure a different name if you need to. See Following relationships "backward" in the queries documentation.
You can try this!

I have the same problem with Django 1.9 and 1.10. This code works!
import datetime
datetime.datetime.now().strftime ("%Y%m%d")
20151015
For the time
from time import gmtime, strftime
showtime = strftime("%Y-%m-%d %H:%M:%S", gmtime())
print showtime

You can use django's filter
with datetime.date
objects:
import datetime
samples = Sample.objects.filter(sampledate__gte=datetime.date(2011, 1, 1),
sampledate__lte=datetime.date(2011, 1, 31))
import datetime
def age(date_of_birth):
if date_of_birth > datetime.date.today().replace(year = date_of_birth.year):
return datetime.date.today().year - date_of_birth.year - 1
else:
return datetime.date.today().year - date_of_birth.year
In your case:
import datetime
# your model
def age(self):
if self.birthdate > datetime.date.today().replace(year = self.birthdate.year):
return datetime.date.today().year - self.birthdate.year - 1
else:
return datetime.date.today().year - self.birthdate.year
You could also use lambda
. Useful if you're using django.utils.timezone.now
date = models.DateField(_("Date"), default=lambda: now().date())
The current v2
registry now supports deleting via DELETE /v2/<name>/manifests/<reference>
See: https://github.com/docker/distribution/blob/master/docs/spec/api.md#deleting-an-image
Working usage: https://github.com/byrnedo/docker-reg-tool
Edit:
The manifest <reference>
above can be retrieved from requesting to
GET /v2/<name>/manifests/<tag>
and checking the Docker-Content-Digest
header in the response.
Edit 2: You may have to run your registry with the following env set:
REGISTRY_STORAGE_DELETE_ENABLED="true"
Edit3: You may have to run garbage collection to free this disk space: https://docs.docker.com/registry/garbage-collection/

If you want to get list of all files in a commit, you can use
git ls-tree --name-only -r <commit-ish>
setTimeout(expression, timeout);
runs the code/function once after the timeout.
setInterval(expression, timeout);
runs the code/function in intervals, with the length of the timeout between them.
Example:
var intervalID = setInterval(alert, 1000); // Will alert every second.
// clearInterval(intervalID); // Will clear the timer.
setTimeout(alert, 1000); // Will alert once, after a second.
There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:
pause
to the batch file so that you can see what is happening before it exits.
.bat
files and select "edit". This will open the file in notepad.pause
.- OR -
.bat
files are located, hold down the "shift" key and right click in the white space.Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.
In the docs for angular.Module
, there's an entry describing the run
function:
Use this method to register work which should be performed when the injector is done loading all modules.
So if you have some module that is your app:
var app = angular.module('app', [/* module dependencies */]);
You can run stuff after the modules have loaded with:
app.run(function() {
// Do post-load initialization stuff here
});
So it's been pointed out that the run
doesn't get called when the DOM is ready and linked up. It gets called when the $injector
for the module referenced by ng-app
has loaded all its dependencies, which is separate from the DOM compilation step.
I took another look at manual initialization, and it seems that this should do the trick.
I've made a fiddle to illustrate.
The HTML is simple:
<html>
<body>
<test-directive>This is a test</test-directive>
</body>
</html>
Note the lack of an ng-app
. And I have a directive that will do some DOM manipulation, so we can make sure of the order and timing of things.
As usual, a module is created:
var app = angular.module('app', []);
And here's the directive:
app.directive('testDirective', function() {
return {
restrict: 'E',
template: '<div class="test-directive"><h1><div ng-transclude></div></h1></div>',
replace: true,
transclude: true,
compile: function() {
console.log("Compiling test-directive");
return {
pre: function() { console.log("Prelink"); },
post: function() { console.log("Postlink"); }
};
}
};
});
We're going to replace the test-directive
tag with a div
of class test-directive
, and wrap its contents in an h1
.
I've added a compile function that returns both pre and post link functions so we can see when these things run.
Here's the rest of the code:
// The bootstrapping process
var body = document.getElementsByTagName('body')[0];
// Check that our directive hasn't been compiled
function howmany(classname) {
return document.getElementsByClassName(classname).length;
}
Before we've done anything, there should be no elements with a class of test-directive
in the DOM, and after we're done there should be 1.
console.log('before (should be 0):', howmany('test-directive'));
angular.element(document).ready(function() {
// Bootstrap the body, which loades the specified modules
// and compiled the DOM.
angular.bootstrap(body, ['app']);
// Our app is loaded and the DOM is compiled
console.log('after (should be 1):', howmany('test-directive'));
});
It's pretty straightforward. When the document is ready, call angular.bootstrap
with the root element of your app and an array of module names.
In fact, if you attach a run
function to the app
module, you'll see it gets run before any of the compiling takes place.
If you run the fiddle and watch the console, you'll see the following:
before (should be 0): 0
Compiling test-directive
Prelink
Postlink
after (should be 1): 1 <--- success!
You could use these functions:
sp_help TableName
sp_helptext ProcedureName
To completely remove a button from its parent layout:
((ViewGroup)button.getParent()).removeView(button);
It is better to use scanf(" %[^\n]",str) in c++ than cin.ignore() after cin>> statement.To do that first you have to include < cstdio > header.
In your case (and in most use cases I have seen), all you need is:
$("#baba").val("");
The short version can be like this:
const diff = (a, b) => b.filter((i) => a.indexOf(i) === -1);
result:
diff(['a', 'b'], ['a', 'b', 'c', 'd']);
["c", "d"]
For reference, these are very similar questions.
These seem to work the best for me. They also work with spaces, and don't re-add ignored files. I didn't see them listed on any of the other answers I saw.
adding:
svn st | grep ^? | sed 's/? //' | xargs svn add
removing:
svn st | grep ^! | sed 's/! //' | xargs svn rm
Edit: It's important to NOT use "add *" if you want to keep your ignored files, otherwise everything that was ignored will be re-added.
See here if you want to grant a Facebook App permanent access to a page (even when you / the app owner are logged out):

Complementing the accepted answer, if you use SELECT2 plugin, you need to recall select2 script to make changes is all select2 fields:
function resetForm(formId){
$('#'+formId).find('input:text, input:password, input:file, select, select2, textarea').val('');
$('#'+formId).find('input:radio, input:checkbox').removeAttr('checked').removeAttr('selected');
$('.select2').select2();
}
I assume you know what a byte is. A byte array is simply an area of memory containing a group of contiguous (side by side) bytes, such that it makes sense to talk about them in order: the first byte, the second byte etc..
Just as bytes can encode different types and ranges of data (numbers from 0 to 255, numbers from -128 to 127, single characters using ASCII e.g. 'a' or '%', CPU op-codes), each byte in a byte array may be any of these things, or contribute to some multi-byte values such as numbers with larger range (e.g. 16-bit unsigned int from 0..65535), international character sets, textual strings ("hello"), or part/all of a compiled computer programs.
The crucial thing about a byte array is that it gives indexed (fast), precise, raw access to each 8-bit value being stored in that part of memory, and you can operate on those bytes to control every single bit. The bad thing is the computer just treats every entry as an independent 8-bit number - which may be what your program is dealing with, or you may prefer some powerful data-type such as a string that keeps track of its own length and grows as necessary, or a floating point number that lets you store say 3.14 without thinking about the bit-wise representation. As a data type, it is inefficient to insert or remove data near the start of a long array, as all the subsequent elements need to be shuffled to make or fill the gap created/required.
Have you tried
document.getElementById('body').style.display = "none";
instead of
document.getElementById('body').style.display = "hidden";
?
public static string ToLeadZeros(this int strNum, int num)
{
var str = strNum.ToString();
return str.PadLeft(str.Length + num, '0');
}
// var i = 1;
// string num = i.ToLeadZeros(5);
Ok, I had the same problem.I came up with this solution.It worked for me the best.I did try atoi() but didn't work well for me.So here is my solution:
void splitInput(int arr[], int sizeArr, char num[])
{
for(int i = 0; i < sizeArr; i++)
// We are subtracting 48 because the numbers in ASCII starts at 48.
arr[i] = (int)num[i] - 48;
}
Sure you can. Something like:
HTML
<div ng-controller="fessCntrl">
<label ng-repeat="(key,val) in list">
<input type="radio" name="localityTypeRadio" ng-model="$parent.localityTypeRadio" ng-value="key" />{{key}}
<div ng-if="key == 'City' || key == 'County'">
<pre>City or County !!! {{$parent.localityTypeRadio}}</pre>
</div>
<div ng-if="key == 'Town'">
<pre>Town!!! {{$parent.localityTypeRadio}}</pre>
</div>
</label>
</div>
JS
var fessmodule = angular.module('myModule', []);
fessmodule.controller('fessCntrl', function ($scope) {
$scope.list = {
City: [{name: "cityA"}, {name: "cityB"}],
County: [{ name: "countyA"}, {name: "countyB"}],
Town: [{ name: "townA"}, {name: "townB"}]
};
$scope.localityTypeRadio = 'City';
});
fessmodule.$inject = ['$scope'];

np.fliplr()
flips the array left to right.
Note that for 1d arrays, you need to trick it a bit:
arr1d = np.array(some_sequence)
reversed_arr = np.fliplr([arr1d])[0]
I saw similar issues (particularly with depth) on some legacy projects when we were cloning that used to live on TFS. Enabling long paths resolved our issue and may be something else worth trying.
git config --system core.longpaths true
It can be done using a single line:
perl -pi.back -e 's/oldString/newString/g;' inputFileName
Pay attention that oldString
is processed as a Regular Expression.
In case the string contains any of {}[]()^$.|*+?
(The special characters for Regular Expression syntax) make sure to escape them unless you want it to be processed as a regular expression.
Escaping it is done by \
, so \[
.
Simply add these to your ggplot:
+ scale_x_continuous(expand = c(0, 0), limits = c(0, NA)) +
scale_y_continuous(expand = c(0, 0), limits = c(0, NA))
df <- data.frame(x = 1:5, y = 1:5)
p <- ggplot(df, aes(x, y)) + geom_point()
p <- p + expand_limits(x = 0, y = 0)
p # not what you are looking for
p + scale_x_continuous(expand = c(0, 0), limits = c(0,NA)) +
scale_y_continuous(expand = c(0, 0), limits = c(0, NA))
Lastly, take great care not to unintentionally exclude data off your chart. For example, a position = 'dodge'
could cause a bar to get left off the chart entirely (e.g. if its value is zero and you start the axis at zero), so you may not see it and may not even know it's there. I recommend plotting data in full first, inspect, then use the above tip to improve the plot's aesthetics.
Two issues with answers given so far, if , for instance, one streams such non-standard JSON. Because then one might have to interpret an incoming string (not a python dictionary).
Issue 1 - demjson
:
With Python 3.7.+ and using conda I wasn't able to install demjson since obviosly it does not support Python >3.5 currently. So I need a solution with simpler means, for instance ast
and/or json.dumps
.
Issue 2 - ast
& json.dumps
:
If a JSON is both single quoted and contains a string in at least one value, which in turn contains single quotes, the only simple yet practical solution I have found is applying both:
In the following example we assume line
is the incoming JSON string object :
>>> line = str({'abc':'008565','name':'xyz','description':'can control TV\'s and more'})
Step 1: convert the incoming string into a dictionary using ast.literal_eval()
Step 2: apply json.dumps
to it for the reliable conversion of keys and values, but without touching the contents of values:
>>> import ast
>>> import json
>>> print(json.dumps(ast.literal_eval(line)))
{"abc": "008565", "name": "xyz", "description": "can control TV's and more"}
json.dumps
alone would not do the job because it does not interpret the JSON, but only see the string. Similar for ast.literal_eval()
: although it interprets correctly the JSON (dictionary), it does not convert what we need.
It might be that the package "Combinations" is not updated anymore and does not work with a recent version of R (I was also unable to install it on R 2.13.1 on windows). The package "combinat" installs without problem for me and might be a solution for you depending on what exactly you're trying to do.
IPInfoDB has an API that you can call in order to find a location based on an IP address.
For "City Precision", you call it like this (you'll need to register to get a free API key):
http://api.ipinfodb.com/v2/ip_query.php?key=<your_api_key>&ip=74.125.45.100&timezone=false
Here's an example in both VB and C# that shows how to call the API.
ZoneId usersTimeZone = ZoneId.of("Asia/Tashkent");
Locale usersLocale = Locale.forLanguageTag("ga-IE");
DateTimeFormatter formatter = DateTimeFormatter.ofLocalizedDateTime(FormatStyle.MEDIUM)
.withLocale(usersLocale);
long microsSince1970 = 1_512_345_678_901_234L;
long secondsSince1970 = TimeUnit.MICROSECONDS.toSeconds(microsSince1970);
long remainingMicros = microsSince1970 - TimeUnit.SECONDS.toMicros(secondsSince1970);
ZonedDateTime dateTime = Instant.ofEpochSecond(secondsSince1970,
TimeUnit.MICROSECONDS.toNanos(remainingMicros))
.atZone(usersTimeZone);
String dateTimeInUsersFormat = dateTime.format(formatter);
System.out.println(dateTimeInUsersFormat);
The above snippet prints:
4 Noll 2017 05:01:18
“Noll” is Gaelic for December, so this should make your user happy. Except there may be very few Gaelic speaking people living in Tashkent, so please specify the user’s correct time zone and locale yourself.
I am taking seriously that you got microseconds from your database. If second precision is fine, you can do without remainingMicros
and just use the one-arg Instant.ofEpochSecond()
, which will make the code a couple of lines shorter. Since Instant
and ZonedDateTime
do support nanosecond precision, I found it most correct to keep the full precision of your timestamp. If your timestamp was in milliseconds rather than microseconds (which they often are), you may just use Instant.ofEpochMilli()
.
The answers using Date
, Calendar
and/or SimpleDateFormat
were fine when this question was asked 7 years ago. Today those classes are all long outdated, and we have so much better in java.time
, the modern Java date and time API.
For most uses I recommend you use the built-in localized formats as I do in the code. You may experiment with passing SHORT
, LONG
or FULL
for format style. Yo may even specify format style for the date and for the time of day separately using an overloaded ofLocalizedDateTime
method. If a specific format is required (this was asked in a duplicate question), you can have that:
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("HH:mm:ss, dd/MM/uuuu");
Using this formatter instead we get
05:01:18, 04/12/2017

Most likely the reason your push did not work is order of execution.
use
is a compile time directive. You push
is done at execution time:
push ( @INC,"directory_path/more_path");
use Foo.pm; # In directory path/more_path
You can use a BEGIN block to get around this problem:
BEGIN {
push ( @INC,"directory_path/more_path");
}
use Foo.pm; # In directory path/more_path
IMO, it's clearest, and therefore best to use lib
:
use lib "directory_path/more_path";
use Foo.pm; # In directory path/more_path
See perlmod for information about BEGIN and other special blocks and when they execute.
Edit
For loading code relative to your script/library, I strongly endorse File::FindLib
You can say use File::FindLib 'my/test/libs';
to look for a library directory anywhere above your script in the path.
Say your work is structured like this:
/home/me/projects/
|- shared/
| |- bin/
| `- lib/
`- ossum-thing/
`- scripts
|- bin/
`- lib/
Inside a script in ossum-thing/scripts/bin
:
use File::FindLib 'lib/';
use File::FindLib 'shared/lib/';
Will find your library directories and add them to your @INC
.
It's also useful to create a module that contains all the environment set-up needed to run your suite of tools and just load it in all the executables in your project.
use File::FindLib 'lib/MyEnvironment.pm'
See http://msdn.microsoft.com/en-us/library/ms187928.aspx
You can concatenate it:
SELECT CONVERT(VARCHAR(10), GETDATE(), 104) + ' ' + CONVERT(VARCHAR(8), GETDATE(), 108)
Another option to avoid nesting two different environments (like multicols
and enumerate
).
The environment called tasks
from the package with the same name seems to me very easy to customize thanks to a variety of options (pdf guide here).
This code:
\documentclass{article}
\usepackage{tasks}
%\settasks{style=itemize}
\begin{document}
Text text text text text text text text text text text text
text text text text text text text text text text text text
text text text text text text text text text text text text.
\begin{tasks}(2)
\task[*] a
\task[*] b
\task[*] c
\task[*] d
\task[*] e
\task[*] f
\end{tasks}
Text text text text text text text text text text text text
text text text text text text text text text text text text
text text text text text text text text text text text text.
\end{document}
produces this output
The package tasks
was updated in August 2020 and it was originally created specifically for horizontally columned lists (see the screenshot just above here), the motivations behind this are resumed in the guide. If such arrangement of the items/tasks is acceptable, then this may be a good choice since it keeps - IMHO - the code tidy and flexible.
alternatively you can retrieve DOM properties
with .prop
here is sample code for select box
if( ctrl.prop('type') == 'select-one' ) { // for single select }
if( ctrl.prop('type') == 'select-multiple' ) { // for multi select }
for textbox
if( ctrl.prop('type') == 'text' ) { // for text box }
To really slow things down and perform a lot of runtime checking, try adding the following at the top of your main()
or equivalent in Microsoft Visual Studio C++
_CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF | _CRTDBG_CHECK_ALWAYS_DF );
Use
print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))
like this:
>>> my_string = "deadbeef"
>>> print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))
0xde 0xad 0xbe 0xef
>>>
On an unrelated side note ... using string
as a variable name even as an example variable name is very bad practice.
Just drop
<script>
myfunction();
</script>
in the body where you want it to be called, understanding that when the page loads and the browser reaches that point, that's when the call will occur.
browser's back/forward button solution
I encountered the same problem and I solved it using the popstate event
from the $window object and ui-router's $state object
. A popstate event is dispatched to the window every time the active history entry changes.
The $stateChangeSuccess
and $locationChangeSuccess
events are not triggered on browser's button click even though the address bar indicates the new location.
So, assuming you've navigated from states main
to folder
to main
again, when you hit back
on the browser, you should be back to the folder
route. The path is updated but the view is not and still displays whatever you have on main
. try this:
angular
.module 'app', ['ui.router']
.run($state, $window) {
$window.onpopstate = function(event) {
var stateName = $state.current.name,
pathname = $window.location.pathname.split('/')[1],
routeParams = {}; // i.e.- $state.params
console.log($state.current.name, pathname); // 'main', 'folder'
if ($state.current.name.indexOf(pathname) === -1) {
// Optionally set option.notify to false if you don't want
// to retrigger another $stateChangeStart event
$state.go(
$state.current.name,
routeParams,
{reload:true, notify: false}
);
}
};
}
back/forward buttons should work smoothly after that.
note: check browser compatibility for window.onpopstate() to be sure
Use btn-block
class on your button/element
Use input-block-level
class on your button/element
Other possible situation: you have multiple users defined in your server environment. In that case, running
passenger-config --ruby-command
will give you the necessary command to specify your nginx/sites-enabled/relevant_application
file with your use case, example:
passenger-config was invoked through the following Ruby interpreter:
Command: /home/other_user/.rbenv/versions/2.4.5/bin/ruby
Version: ruby 2.4.5p335 (2018-10-18 revision 65137) [x86_64-linux]
To use in Apache: PassengerRuby /home/other_user/.rbenv/versions/2.4.5/bin/ruby
To use in Nginx : passenger_ruby /home/other_user/.rbenv/versions/2.4.5/bin/ruby
To use with Standalone: /home/other_user/.rbenv/versions/2.4.5/bin/ruby /usr/bin/passenger start
invalidate cache in android studio will resolve this issue. Go to file-> click on invalidate cache/restart option.
I was able to solve this problem by executing this statement
sudo dpkg-reconfigure mysql-server-5.5
Which will change the root password.
Assuming you've got access to a standard Unix shell and/or cygwin environment:
tr -s ' ' '\n' < yourfile | sort | uniq -d -c
^--space char
Basically: convert all space characters to linebreaks, then sort the tranlsated output and feed that to uniq and count duplicate lines.
You may actually go with ViewChild API
...
parent.ts
<button (click)="clicked()">click</button>
export class App {
@ViewChild(Child) vc:Child;
constructor() {
this.name = 'Angular2'
}
func(e) {
console.log(e)
}
clicked(){
this.vc.getName();
}
}
child.ts
export class Child implements OnInit{
onInitialized = new EventEmitter<Child>();
...
...
getName()
{
console.log('called by vc')
console.log(this.name);
}
}
You need to multi value check. Try using the following code :
<?php
$illstack=array(...............);
$val=array('uk','bn','in');
if(count(array_intersect($illstack,$val))===count($val)){ // all of $val is in $illstack}
?>
There is a way to iterate throw rows while getting a DataFrame in return, and not a Series. I don't see anyone mentioning that you can pass index as a list for the row to be returned as a DataFrame:
for i in range(len(df)):
row = df.iloc[[i]]
Note the usage of double brackets. This returns a DataFrame with a single row.
The other answers are what you asked about, but in case it’s useful to anyone else, here’s how to set the font conditionally from the screen DPI (Windows only):

"get dpi, strip out utf-16 garbage and new lines
"system() converts 0x00 to 0x01 for 'platform independence'
"should return something like 'PixelsPerXLogicalInch=192'
"get the part from the = to the end of the line (eg '=192') and strip
"the first character

Eaven if you are going to prevent sql injection front-end, using html or js checks, you'd have to consider that front-end checks are "bypassable".
You can disable js or edit a pattern with a front-end development tool (built in with firefox or chrome nowadays).
So, in order to prevent SQL injection, would be right to sanitize input date backend inside your controller.
I would like to suggest to you to use filter_input() native PHP function in order to sanitize GET and INPUT values.
If you want to go ahead with security, for sensible database queries, I'd like to suggest to you to use regular expression to validate data format. preg_match() will help you in this case! But take care! Regex engine is not so light. Use it only if necessary, otherwise your application performances will decrease.
Security has a costs, but do not waste your performance!
Easy example:
if you want to double check if a value, received from GET is a number, less then 99 if(!preg_match('/[0-9]{1,2}/')){...} is heavyer of
if (isset($value) && intval($value)) <99) {...}
So, the final answer is: "No! PDO Prepared Statements does not prevent all kind of sql injection"; It does not prevent unexpected values, just unexpected concatenation
I just run this command as a root from terminal and problem is solved,
sudo apt-get install -y postgis postgresql-9.3-postgis-2.1
pip install psycopg2
or
sudo apt-get install libpq-dev python-dev
pip install psycopg2
With ES6 syntax
import mongoose from "mongoose";
// Generate a new new ObjectId
const newId2 = new mongoose.Types.ObjectId();
// Convert string to ObjectId
const newId = new mongoose.Types.ObjectId('56cb91bdc3464f14678934ca');
I came across the same situation, I found the answer with use of socket library helpful but it doesn't provide support for ipv6 addresses. Found a better way for it:
Unfortunately it Works for python3 only
import ipaddress
def valid_ip(address):
try:
print ipaddress.ip_address(address)
return True
except:
return False
print valid_ip('10.10.20.30')
print valid_ip('2001:DB8::1')
print valid_ip('gibberish')
Since method public void setColorFilter(@ColorInt int color, @NonNull PorterDuff.Mode mode)
is deprecated, I use such form:
progressBar.indeterminateDrawable.colorFilter =
PorterDuffColorFilter(ContextCompat.getColor(this, R.color.black), PorterDuff.Mode.SRC_IN)
use below statement if safe_mode
is off
set_time_limit(0);
For equals, look into Secrets of Equals by Angelika Langer. I love it very much. She's also a great FAQ about Generics in Java. View her other articles here (scroll down to "Core Java"), where she also goes on with Part-2 and "mixed type comparison". Have fun reading them!
If ||
as a replacement of C#'s ??
isn't good enough in your case, because it swallows empty strings and zeros, you can always write your own function:
function $N(value, ifnull) {
if (value === null || value === undefined)
return ifnull;
return value;
}
var whatIWant = $N(someString, 'Cookies!');
var pinIcon = new google.maps.MarkerImage(
"http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
null, /* size is determined at runtime */
null, /* origin is 0,0 */
null, /* anchor is bottom center of the scaled image */
new google.maps.Size(12, 18)
);
Using Math.round()
will round the float to the nearest integer.
Sadly, no.
I agree that such frequent operation should have easier implementation than copying of input line by line in loop, but you'll have to either write helper method or use external library.
The Doc of the npm defines that only tag/version can be specified after repo_url.
Here is the Doc: https://docs.npmjs.com/cli/install
In C++ the stack memory is where local variables get stored/constructed. The stack is also used to hold parameters passed to functions.
The stack is very much like the std::stack class: you push parameters onto it and then call a function. The function then knows that the parameters it expects can be found on the end of the stack. Likewise, the function can push locals onto the stack and pop them off it before returning from the function. (caveat - compiler optimizations and calling conventions all mean things aren't this simple)
The stack is really best understood from a low level and I'd recommend Art of Assembly - Passing Parameters on the Stack. Rarely, if ever, would you consider any sort of manual stack manipulation from C++.
Generally speaking, the stack is preferred as it is usually in the CPU cache, so operations involving objects stored on it tend to be faster. However the stack is a limited resource, and shouldn't be used for anything large. Running out of stack memory is called a Stack buffer overflow. It's a serious thing to encounter, but you really shouldn't come across one unless you have a crazy recursive function or something similar.
Heap memory is much as rskar says. In general, C++ objects allocated with new, or blocks of memory allocated with the likes of malloc end up on the heap. Heap memory almost always must be manually freed, though you should really use a smart pointer class or similar to avoid needing to remember to do so. Running out of heap memory can (will?) result in a std::bad_alloc.
An abstract class can not be directly instantiated, but must be derived from to be usable. A class MUST be abstract if it contains abstract methods: either directly
abstract class Foo {
abstract void someMethod();
}
or indirectly
interface IFoo {
void someMethod();
}
abstract class Foo2 implements IFoo {
}
However, a class can be abstract without containing abstract methods. Its a way to prevent direct instantation, e.g.
abstract class Foo3 {
}
class Bar extends Foo3 {
}
Foo3 myVar = new Foo3(); // illegal! class is abstract
Foo3 myVar = new Bar(); // allowed!
The latter style of abstract classes may be used to create "interface-like" classes. Unlike interfaces an abstract class is allowed to contain non-abstract methods and instance variables. You can use this to provide some base functionality to extending classes.
Another frequent pattern is to implement the main functionality in the abstract class and define part of the algorithm in an abstract method to be implemented by an extending class. Stupid example:
abstract class Processor {
protected abstract int[] filterInput(int[] unfiltered);
public int process(int[] values) {
int[] filtered = filterInput(values);
// do something with filtered input
}
}
class EvenValues extends Processor {
protected int[] filterInput(int[] unfiltered) {
// remove odd numbers
}
}
class OddValues extends Processor {
protected int[] filterInput(int[] unfiltered) {
// remove even numbers
}
}
1) use for tommorow's date startDate: '+1d'

CheckLogin(uName, pswod);
It's simple :
Let's imagine that you are trying to upload a file within js framework, ajax request or mobile application (Client side)
Here how to do it using PHP
<?php
$base64String = "kfezyufgzefhzefjizjfzfzefzefhuze"; // I put a static base64 string, you can implement you special code to retrieve the data received via the request.
$filePath = "/MyProject/public/uploads/img/test.png";
file_put_contents($filePath, base64_decode($base64String));
?>
First things first, if the date property is storing a date, store it using a DateTime. If you parse the date through the sort you have to parse it for each item being compared, that's not very efficient...
You can then make an IComparer:
public class TagComparer : IComparer<cTag>
{
public int Compare(cTag first, cTag second)
{
if (first != null && second != null)
{
// We can compare both properties.
return first.date.CompareTo(second.date);
}
if (first == null && second == null)
{
// We can't compare any properties, so they are essentially equal.
return 0;
}
if (first != null)
{
// Only the first instance is not null, so prefer that.
return -1;
}
// Only the second instance is not null, so prefer that.
return 1;
}
}
var list = new List<cTag>();
// populate list.
list.Sort(new TagComparer());
You can even do it as a delegate:
list.Sort((first, second) =>
{
if (first != null && second != null)
return first.date.CompareTo(second.date);
if (first == null && second == null)
return 0;
if (first != null)
return -1;
return 1;
});

Screen
If process is running in a screen session you can use screen's log command to log the output of that window to a file:
Switch to the script's window, C-a H to log.
Now you can :
$ tail -f screenlog.2 | grep whatever
From screen's man page:
log [on|off]
Start/stop writing output of the current window to a file "screenlog.n" in the window's default directory, where n is the number of the current window. This filename can be changed with the 'logfile' command. If no parameter is given, the state of logging is toggled. The session log is appended to the previous contents of the file if it already exists. The current contents and the contents of the scrollback history are not included in the session log. Default is 'off'.
I'm sure tmux has something similar as well.
You can also create a project repository. It's useful if more developers are working on the same project, and the library must be included in the project.
First, create a repository structure in your project's lib directory, and then copy the library into it. The library must have following name-format: <artifactId>-<version>.jar
<your_project_dir>/lib/com/microsoft/sqlserver/<artifactId>/<version>/
Create pom file next to the library file, and put following information into it:
<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.2.0</modelVersion>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.2</version>
</project>
At this point, you should have this directory structure:
<your_project_dir>/lib/com/microsoft/sqlserver/sqljdbc4/4.2/sqljdbc4-4.2.jar
<your_project_dir>/lib/com/microsoft/sqlserver/sqljdbc4/4.2/sqljdbc4-4.2.pom
Go to your project's pom file and add new repository:
<repositories>
<repository>
<id>Project repository</id>
<url>file://${basedir}/lib</url>
</repository>
</repositories>
Finally, add a dependency on the library:
<dependencies>
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>sqljdbc4</artifactId>
<version>4.2</version>
</dependency>
</dependencies>
Update 2017-03-04
It seems like the library can be obtained from publicly available repository. @see nirmal's and Jacek Grzelaczyk's answers for more details.
Update 2020-11-04
Currently Maven has a convenient target install
which allow you to deploy an existing package into a project / file repository without the need of creating POM files manually. It will generate those files for you.
mvn install:install-file \
-Dfile=sqljdbc4.jar \
-DgroupId=com.microsoft.sqlserver \
-DartifactId=sqljdbc4 \
-Dversion=4.2 \
-Dpackaging=jar \
-DlocalRepositoryPath=${your_project_dir}/lib
Elements are added to list using append()
:
>>> data = {'list': [{'a':'1'}]}
>>> data['list'].append({'b':'2'})
>>> data
{'list': [{'a': '1'}, {'b': '2'}]}
If you want to add element to a specific place in a list (i.e. to the beginning), use insert()
instead:
>>> data['list'].insert(0, {'b':'2'})
>>> data
{'list': [{'b': '2'}, {'a': '1'}]}
After doing that, you can assemble JSON again from dictionary you modified:
>>> json.dumps(data)
'{"list": [{"b": "2"}, {"a": "1"}]}'
We're using Kafka 2.11 and make use of this tool - kafka-consumer-groups
.
$ rpm -qf /bin/kafka-consumer-groups
confluent-kafka-2.11-1.1.1-1.noarch
For example:
$ kafka-consumer-groups --describe --group logstash | grep -E "TOPIC|filebeat"

:
alias kafka-consumer-groups="KAFKA_JVM_PERFORMANCE_OPTS=\"-Djava.security.auth.login.config=$HOME/.kafka_client_jaas.conf\" kafka-consumer-groups --bootstrap-server ${KAFKA_HOSTS} --command-config /etc/kafka/security-enabler.properties"
Yes, there is a maximum, but it's system dependent. Try it and see, doubling until you hit a limit then searching down. At least with Sun JRE 1.6 on linux you get interesting if not always informative error messages (peregrino is netbook running 32 bit ubuntu with 2G RAM and no swap):
peregrino:$ java -Xmx4096M -cp bin WheelPrimes
Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.
peregrino:$ java -Xmx4095M -cp bin WheelPrimes
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified
peregrino:$ java -Xmx4092M -cp bin WheelPrimes
Error occurred during initialization of VM
The size of the object heap + VM data exceeds the maximum representable size
peregrino:$ java -Xmx4000M -cp bin WheelPrimes
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
(experiment reducing from 4000M until)
peregrino:$ java -Xmx2686M -cp bin WheelPrimes
(normal execution)
Most are self explanatory, except -Xmx4095M which is rather odd (maybe a signed/unsigned comparison?), and that it claims to reserve 2686M on a 2GB machine with no swap. But it does hint that the maximum size is 4G not 2G for a 32 bit VM, if the OS allows you to address that much.
This is a cheap deep merge that uses as little code as I could think of. Each source overwrites the previous property when it exists.
const { keys } = Object;
const isObject = a => typeof a === "object" && !Array.isArray(a);
const merge = (a, b) =>
isObject(a) && isObject(b)
? deepMerge(a, b)
: isObject(a) && !isObject(b)
? a
: b;
const coalesceByKey = source => (acc, key) =>
(acc[key] && source[key]
? (acc[key] = merge(acc[key], source[key]))
: (acc[key] = source[key])) && acc;
/**
* Merge all sources into the target
* overwriting primitive values in the the accumulated target as we go (if they already exist)
* @param {*} target
* @param {...any} sources
*/
const deepMerge = (target, ...sources) =>
sources.reduce(
(acc, source) => keys(source).reduce(coalesceByKey(source), acc),
target
);
console.log(deepMerge({ a: 1 }, { a: 2 }));
console.log(deepMerge({ a: 1 }, { a: { b: 2 } }));
console.log(deepMerge({ a: { b: 2 } }, { a: 1 }));
The reason this is wrong:
if (title == "User greeting" || "User name") {do stuff};
is because what that's saying is
If title equals the string "User greeting"
or just "User name" (not if title equals the string "User name"). The part after your or would be like writing
if ("User name")
which c# doesn't know what to do with. It can't figure out how to get a boolean out of "User name"
You need to add the content-disposition header to the response:
response.StatusCode = HttpStatusCode.OK;
response.Content = new StreamContent(result);
response.AppendHeader("content-disposition", "attachment; filename=" + fileName);
return response;
Syntax: ALTER TABLE table_name CHANGE old_column_name new_column_name datatype;
If table name is Student and column name is Name. Then, if you want to change Name to First_Name
ALTER TABLE Student CHANGE Name First_Name varchar(20);
Though this might be too late to comment but here's the working code for problems such as yours.
<div id="player">
<audio autoplay hidden>
<source src="link/to/file/file.mp3" type="audio/mpeg">
If you're reading this, audio isn't supported.
</audio>
</div>
Using this:
if (navigator.userAgent.match("MSIE")) {}
The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc
A set of simple examples:
Using Gson:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
public class Gson {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
com.google.gson.Gson gson = new com.google.gson.Gson();
Response respuesta = gson.fromJson(json, Response.class);
System.out.println(respuesta.getExample());
System.out.println(respuesta.getFr());
} catch (IOException ex) {
}
return null;
}
public class Response{
private String example;
private String fr;
public String getExample() {
return example;
}
public void setExample(String example) {
this.example = example;
}
public String getFr() {
return fr;
}
public void setFr(String fr) {
this.fr = fr;
}
}
}
Using json-simple:
import java.io.IOException;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
public class JsonSimple {
public static void main(String[] args) {
}
public HttpResponse http(String url, String body) {
try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
HttpPost request = new HttpPost(url);
StringEntity params = new StringEntity(body);
request.addHeader("content-type", "application/json");
request.setEntity(params);
HttpResponse result = httpClient.execute(request);
String json = EntityUtils.toString(result.getEntity(), "UTF-8");
try {
JSONParser parser = new JSONParser();
Object resultObject = parser.parse(json);
if (resultObject instanceof JSONArray) {
JSONArray array=(JSONArray)resultObject;
for (Object object : array) {
JSONObject obj =(JSONObject)object;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
}else if (resultObject instanceof JSONObject) {
JSONObject obj =(JSONObject)resultObject;
System.out.println(obj.get("example"));
System.out.println(obj.get("fr"));
}
} catch (Exception e) {
// TODO: handle exception
}
} catch (IOException ex) {
}
return null;
}
}
etc...
Checkout the entry on the numpy example list. Here is the entry on .loadtxt()
>>> from numpy import *
>>>
>>> data = loadtxt("myfile.txt") # myfile.txt contains 4 columns of numbers
>>> t,z = data[:,0], data[:,3] # data is 2D numpy array
>>>
>>> t,x,y,z = loadtxt("myfile.txt", unpack=True) # to unpack all columns
>>> t,z = loadtxt("myfile.txt", usecols = (0,3), unpack=True) # to select just a few columns
>>> data = loadtxt("myfile.txt", skiprows = 7) # to skip 7 rows from top of file
>>> data = loadtxt("myfile.txt", comments = '!') # use '!' as comment char instead of '#'
>>> data = loadtxt("myfile.txt", delimiter=';') # use ';' as column separator instead of whitespace
>>> data = loadtxt("myfile.txt", dtype = int) # file contains integers instead of floats
To update this for Python-3 you can do this
"{} {}".format(True, False)
However if you want to actually format the string (e.g. add white space), you encounter Python casting the boolean into the underlying C value (i.e. an int), e.g.
>>> "{:<8} {}".format(True, False)
'1 False'
To get around this you can cast True
as a string, e.g.
>>> "{:<8} {}".format(str(True), False)
'True False'
If you can count on having a period of time where the table is in a stable state with no new inserts going on, this should do it (untested):
DECLARE
last_used NUMBER;
curr_seq NUMBER;
BEGIN
SELECT MAX(pk_val) INTO last_used FROM your_table;
LOOP
SELECT your_seq.NEXTVAL INTO curr_seq FROM dual;
IF curr_seq >= last_used THEN EXIT;
END IF;
END LOOP;
END;
This enables you to get the sequence back in sync with the table, without dropping/recreating/re-granting the sequence. It also uses no DDL, so no implicit commits are performed. Of course, you're going to have to hunt down and slap the folks who insist on not using the sequence to populate the column...
Mono Develop is what you want, if you have used visual studio you should find it simple enough to get started.
If I recall correctly you should be able to install with sudo apt-get install monodevelop
Which specific index? If you want 'Add New' to be first on the dropdownlist you can add it though the code like this:
<asp:DropDownList ID="DropDownList1" AppendDataBoundItems="true" runat="server">
<asp:ListItem Text="Add New" Value="0" />

If you want to add it at a different index, maybe the last then try:
ListItem lst = new ListItem ( "Add New" , "0" );
DropDownList1.Items.Insert( DropDownList1.Items.Count-1 ,lst);
The following works for me in Firefox and Internet Explorer:

What I did to print that actual query is a bit complicated but it works :)
In method that assigns variables to my statement I have another variable that looks a bit like this:
$this->fullStmt = str_replace($column, '\'' . str_replace('\'', '\\\'', $param) . '\'', $this->fullStmt);
Where:
$column
is my token
$param
is the actual value being assigned to token
$this->fullStmt
is my print only statement with replaced tokens
What it does is a simply replace tokens with values when the real PDO assignment happens.
I hope I did not confuse you and at least pointed you in right direction.
For that you just need write to some lines
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.setDrawerIndicatorEnabled(true);
toggle.syncState();
toggle.setDrawerIndicatorEnabled(true); if this is false make it true or remove this line
Following your EDIT, here's my suggestion :
If you have only one entry, you might replace the Map by a dual object. Depending on the types, and your preferences:
I redirect stderr
to stdout
and then use grep's invert-match (-v
) to exclude the warning/error string that I want to hide:
grep -r <pattern> * 2>&1 | grep -v "No such file or directory"
Actually you can do it pretty simple, since the list have a ForEach
method and since you can pass in Console.WriteLine
as a method group. The compiler will then use an implicit conversion to convert the method group to, in this case, an Action<int>
and pick the most specific method from the group, in this case Console.WriteLine(int)
:
var list = new List<int>(Enumerable.Range(0, 50));
list.ForEach(Console.WriteLine);
Works with strings too =)
To be utterly pedantic (and I'm not suggesting a change to your answer - just commenting for the sake of interest) Console.WriteLine
is a method group. The compiler then uses an implicit conversion from the method group to Action<int>
, picking the most specific method (Console.WriteLine(int)
in this case).
if you have 4.2 and want to install 5.0.0 then
nvm install v5.0.0 --reinstall-packages-from=4.2
the answer of gabrielperales is right except that he missed the "=" sign at the end. if you don't put the "=" sign then new node version will be installed but the packages won't be installed.

I like to give the users a bit of flexibility and trust, that they will get the format right, but I do want to enforce only digits and two decimals for currency
^[$\-\s]*[\d\,]*?([\.]\d{0,2})?\s*$
Takes care of:
$ 1.
-$ 1.00
$ -1.0
.1
.10
-$ 1,000,000.0
Of course it will also match:
$$--$1,92,9,29.1 => anyway after cleanup => -192,929.10
OP asked about running from node
not from mocha
. This is a very common use case, see Using Mocha Programatically
This is what injected describe and it into my tests.
mocha.ui('bdd').run(function (failures) {
process.on('exit', function () {
process.exit(failures);
});
});
I tried tdd
like in the docs, but that didn't work, bdd worked though.
Here is my solution using tr:
var1=match
var2=MATCH
var1=`echo $var1 | tr '[A-Z]' '[a-z]'`
var2=`echo $var2 | tr '[A-Z]' '[a-z]'`
if [ "$var1" = "$var2" ] ; then
echo "MATCH"

d-block d-md-none
to hide on medium, large and extra large devices.
d-none d-md-block
to hide on small and extra-small devices.
Note that you can also inline by replacing d-*-block
with d-*-inline-block
Old answer: Bootstrap 4 Alpha
You can use the classes .hidden-*-up
to hide on a given size and larger devices
.hidden-md-up
to hide on medium, large and extra large devices.
The same goes with .hidden-*-down
to hide on a given size and smaller devices
.hidden-md-down
to hide on medium, small and extra-small devices
visible-* is no longer an option with bootstrap 4
To display only on medium devices, you can combine the two:
hidden-sm-down
andhidden-xl-up
The valid sizes are:
xs
for phones in portrait mode (<34em)sm
for phones in landscape mode (=34em)md
for tablets (=48em)lg
for desktops (=62em)xl
for desktops (=75em)This was as of Bootstrap 4, alpha 5 (January 2017). More details here: http://v4-alpha.getbootstrap.com/layout/responsive-utilities/
On Bootstrap 4.3.x: https://getbootstrap.com/docs/4.3/utilities/display/
You can work around that via a Live Template. Go to Settings -> Live Template, click the "Add"-Button (green plus on the right).
In the "Abbreviation" field, enter the string that should activate the template (e.g. @a
), and in the "Template Text" area enter the string to complete (e.g. @author - My Name
). Set the "Applicable context" to Java (Comments only maybe) and set a key to complete (on the right).
I tested it and it works fine, however IntelliJ seems to prefer the inbuild templates, so "@a + Tab" only completes "author". Setting the completion key to Space worked however.
To change the user name that is automatically inserted via the File Templates (when creating a class for example), can be changed by adding
-Duser.name=Your name
to the idea.exe.vmoptions or idea64.exe.vmoptions (depending on your version) in the IntelliJ/bin directory.
Restart IntelliJ
You may have enough correct answers for your question but in case your IDE gives you the warning
Promise returned from navigate is ignored
you may either ignore that warning or use this.router.navigate(['/your-path']).then()

@last_run_time
is a 9.4. User-Defined Variables and last_run_time datetime
one 13.6.4.1. Local Variable DECLARE Syntax, are different variables.
Try: SELECT last_run_time;
UPDATE
Example:
/* CODE FOR DEMONSTRATION PURPOSES */
DELIMITER $$
CREATE PROCEDURE `sp_test`()
BEGIN
DECLARE current_procedure_name CHAR(60) DEFAULT 'accounts_general';
DECLARE last_run_time DATETIME DEFAULT NULL;
DECLARE current_run_time DATETIME DEFAULT NOW();
-- Define the last run time
SET last_run_time := (SELECT MAX(runtime) FROM dynamo.runtimes WHERE procedure_name = current_procedure_name);
-- if there is no last run time found then use yesterday as starting point
IF(last_run_time IS NULL) THEN

Though it's an old thread, but adding another option might not harm. (JDK 1.8 lambda functions seem to make it easy);
The problem could be broken down into the following steps;
Here is the function with some description:
/**
* Provided an unsequenced / sequenced list of integers, the function returns unique random IDs as defined by the parameter
* @param numberToGenerate
* @param idList
* @return List of unique random integer values from the provided list
*/
private List<Integer> getUniqueRandomInts(List<Integer> idList, Integer numberToGenerate) {
List<Integer> generatedUniqueIds = new ArrayList<>();
Integer minId = idList.stream().mapToInt (v->v).min().orElseThrow(NoSuchElementException::new);
Integer maxId = idList.stream().mapToInt (v->v).max().orElseThrow(NoSuchElementException::new);
ThreadLocalRandom.current().ints(minId,maxId)
.filter(e->idList.contains(e))
.distinct()
.limit(numberToGenerate)
.forEach(generatedUniqueIds:: add);
return generatedUniqueIds;
}
So that, to get 11 unique random numbers for 'allIntegers' list object, we'll call the function like;
List<Integer> ids = getUniqueRandomInts(allIntegers,11);
The function declares new arrayList 'generatedUniqueIds' and populates with each unique random integer up to the required number before returning.
P.S. ThreadLocalRandom class avoids common seed value in case of concurrent threads.
try the following program
using System;

InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)

System.Data.OleDb.OleDbConnection MyConnection;
System.Data.DataSet DtSet;
System.Data.OleDb.OleDbDataAdapter MyCommand;
MyConnection = new System.Data.OleDb.OleDbConnection(@"provider=Microsoft.Jet.OLEDB.4.0;Data Source='c:\csharp.net-informations.xls';Extended Properties=Excel 8.0;");
MyCommand = new System.Data.OleDb.OleDbDataAdapter("select * from [Sheet1$]", MyConnection);
MyCommand.TableMappings.Add("Table", "Net-informations.com");
DtSet = new System.Data.DataSet();
MyCommand.Fill(DtSet);
dataGridView1.DataSource = DtSet.Tables[0];
MyConnection.Close();
}

A solution that works on my Android 4.2.2, compiled with build target Android 4.4W:
WebSettings settings = webView.getSettings();
settings.setDomStorageEnabled(true);
settings.setDatabaseEnabled(true);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
File databasePath = getDatabasePath("yourDbName");
settings.setDatabasePath(databasePath.getPath());
}
I found theDuncs answer very useful and below you can find my own (refactored) version:
- (void)viewWillAppear:(BOOL)animated {
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}
- (void)viewWillDisappear:(BOOL)animated {
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}
- (void)keyboardWillShow:(NSNotification *)notification {
CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue].size;
float newVerticalPosition = -keyboardSize.height;
[self moveFrameToVerticalPosition:newVerticalPosition forDuration:0.3f];
}
- (void)keyboardWillHide:(NSNotification *)notification {
[self moveFrameToVerticalPosition:0.0f forDuration:0.3f];
}
- (void)moveFrameToVerticalPosition:(float)position forDuration:(float)duration {
CGRect frame = self.view.frame;
frame.origin.y = position;
[UIView animateWithDuration:duration animations:^{
self.view.frame = frame;
}];
}
You're using Comparators
incorrectly.
Collections.sort(movieItems, new Comparator<Movie>(){
public int compare (Movie m1, Movie m2){
return m1.getDate().compareTo(m2.getDate());
}
});
You can use array.nbytes
for numpy arrays, for example:
>>> import numpy as np
>>> from sys import getsizeof
>>> a = [0] * 1024
>>> b = np.array(a)
>>> getsizeof(a)
8264
>>> b.nbytes

In the aspx page load event, add an onkeypress
to the box.
this.TextBox1.Attributes.Add(
"onkeypress", "button_click(this,'" + this.Button1.ClientID + "')");
Then add this javascript to evaluate the key press, and if it is "enter," click the right button.
<script>
function button_click(objTextBox,objBtnID)
{
if(window.event.keyCode==13)
{
document.getElementById(objBtnID).focus();
document.getElementById(objBtnID).click();
}
}
</script>
A small change to your algorithm:
filne = "D:/testtube/testdkanimfilternode.txt"
f = open(filne, 'r+')
while 1:
lines = f.readlines()
if not lines:
break
line_iter= iter(lines) # here
for line in line_iter: # and here
print line
if (line[:5] == "anim "):
print 'next() '
ne = line_iter.next() # and here
print ' ne ',ne,'\n'
break
f.close()
However, using the pairwise
function from itertools
recipes:
def pairwise(iterable):
"s -> (s0,s1), (s1,s2), (s2, s3), ..."
a, b = itertools.tee(iterable)
next(b, None)
return itertools.izip(a, b)
you can change your loop into:
for line, next_line in pairwise(f): # iterate over the file directly
print line
if line.startswith("anim "):
print 'next() '
print ' ne ', next_line, '\n'
break
There is no difference in terms of functionality
The addwithvalue
method takes an object as the value. There is no type data type checking. Potentially, that could lead to error if data type does not match with SQL table. The add
method requires that you specify the Database type first. This helps to reduce such errors.

You may also want to make sure that your code localizes correctly, or make sure the users are used to the "international" notation. For example, "1,112" actually means different numbers across different countries. In Germany it means the number a little over one, instead of one thousand and something.
Corresponding Wikipedia article is at http://en.wikipedia.org/wiki/Decimal_mark. It seems to be poorly written at this time though. For example as a Chinese I'm not sure where does these description about thousand separator in China come from.

You don't need jQuery for this. Here's a simple working example:
<!DOCTYPE html>
<html>
<head>
<title>box-shadow-experiment</title>
<style type="text/css">
#box-shadow-div{
position: fixed;
width: 1px;
height: 1px;
border-radius: 100%;
background-color:black;
box-shadow: 0 0 10px 10px black;
top: 49%;
left: 48.85%;
}
</style>
<script type="text/javascript">
window.onload = function(){
var bsDiv = document.getElementById("box-shadow-div");
var x, y;
// On mousemove use event.clientX and event.clientY to set the location of the div to the location of the cursor:
window.addEventListener('mousemove', function(event){
x = event.clientX;
y = event.clientY;
if ( typeof x !== 'undefined' ){
bsDiv.style.left = x + "px";
bsDiv.style.top = y + "px";
}
}, false);
}
</script>
</head>
<body>
<div id="box-shadow-div"></div>
</body>
</html>
I chose position: fixed;
so scrolling wouldn't be an issue.

Check out the MSDN page for SortedList:
From Remarks section:
The
SortedList<(Of <(TKey, TValue>)>)
generic class is a binary search tree withO(log n)
retrieval, wheren
is the number of elements in the dictionary. In this, it is similar to theSortedDictionary<(Of <(TKey, TValue>)>)
generic class. The two classes have similar object models, and both haveO(log n)
retrieval. Where the two classes differ is in memory use and speed of insertion and removal:
SortedList<(Of <(TKey, TValue>)>)
uses less memory thanSortedDictionary<(Of <(TKey, TValue>)>)
.
SortedDictionary<(Of <(TKey, TValue>)>)
has faster insertion and removal operations for unsorted data,O(log n)
as opposed toO(n)
forSortedList<(Of <(TKey, TValue>)>)
.If the list is populated all at once from sorted data,
SortedList<(Of <(TKey, TValue>)>)
is faster thanSortedDictionary<(Of <(TKey, TValue>)>)
.
My answer is quite easy:
Use Entity Framework for communication between C# and your SQL database. That will make parameterized SQL strings that isn't vulnerable to SQL injection.
As a bonus, it's very easy to work with as well.

You can search for (1...100)! on Wolfram|Alpha to pre-calculate the factorial sequence.
The first 100 numbers are:

If you still want to calculate the values yourself, you can use memoization:
var f = [];
function factorial (n) {
if (n == 0 || n == 1)
return 1;
if (f[n] > 0)
return f[n];
return f[n] = factorial(n-1) * n;
}
I thought it would be useful to add a working example of lazy iterative factorial function that uses big numbers to get exact result with memoization and cache as comparison
var f = [new BigNumber("1"), new BigNumber("1")];
var i = 2;
function factorial(n)
{
if (typeof f[n] != 'undefined')
return f[n];
var result = f[i-1];
for (; i <= n; i++)
f[i] = result = result.multiply(i.toString());
return result;
}
var cache = 100;
// Due to memoization, following line will cache first 100 elements.
factorial(cache);
I assume you would use some kind of closure to limit variable name visibility.
Try ["points.bean.pointsBase"]
It's in the python docs.
import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1),
datetime.time(10, 23))
returns
datetime.datetime(2011, 1, 1, 10, 23)
If you're using .NET 3.5 or .NET 4, it's easy to create the dictionary using LINQ:
Dictionary<string, ArrayList> result = target.GetComponents()
.ToDictionary(x => x.Key, x => x.Value);
There's no such thing as an IEnumerable<T1, T2>
but a KeyValuePair<TKey, TValue>
is fine.
Just for completeness, using the modern .format()
syntax:
>>> numbers = [1, 15, 255]
>>> ''.join('{:02X}'.format(a) for a in numbers)
'010FFF'
This answer is an attempt to explain why Git behaves the way it does. It is not a recommendation to engage in any particular workflows. (My own preference is to just commit anyway, avoiding git stash
and not trying to be too tricky, but others like other methods.)
The observation here is that, after you start working in branch1
(forgetting or not realizing that it would be good to switch to a different branch branch2
first), you run:
git checkout branch2
Sometimes Git says "OK, you're on branch2 now!" Sometimes, Git says "I can't do that, I'd lose some of your changes."
If Git won't let you do it, you have to commit your changes, to save them somewhere permanent. You may want to use git stash
to save them; this is one of the things it's designed for. Note that git stash save
or git stash push
actually means "Commit all the changes, but on no branch at all, then remove them from where I am now." That makes it possible to switch: you now have no in-progress changes. You can then git stash apply
them after switching.
Sidebar:
git stash save
is the old syntax;git stash push
was introduced in Git version 2.13, to fix up some problems with the arguments togit stash
and allow for new options. Both do the same thing, when used in the basic ways.
If Git won't let you switch, you already have a remedy: use git stash
or git commit
; or, if your changes are trivial to re-create, use git checkout -f
to force it. This answer is all about when Git will let you git checkout branch2
even though you started making some changes. Why does it work sometimes, and not other times?
The rule here is simple in one way, and complicated/hard-to-explain in another:
That is—and please note that this is still simplified; there are some extra-difficult corner cases with staged git add
s, git rm
s and such—suppose you are on branch1
. A git checkout branch2
would have to do this:
branch1
and not in branch2
,1 remove that file.branch2
and not in branch1
, create that file (with appropriate contents).branch2
is different, update the working tree version.Each of these steps could clobber something in your work-tree:
branch1
; it's "unsafe" if you've made changes.branch2
is "safe" if it does not exist now.2 It's "unsafe" if it does exist now but has the "wrong" contents.branch1
.Creating a new branch (git checkout -b newbranch
) is always considered "safe": no files will be added, removed, or altered in the work-tree as part of this process, and the index/staging-area is also untouched. (Caveat: it's safe when creating a new branch without changing the new branch's starting-point; but if you add another argument, e.g., git checkout -b newbranch different-start-point
, this might have to change things, to move to different-start-point
. Git will then apply the checkout safety rules as usual.)
1This requires that we define what it means for a file to be in a branch, which in turn requires defining the word branch properly. (See also What exactly do we mean by "branch"?) Here, what I really mean is the commit to which the branch-name resolves: a file whose path is P
is in branch1
if git rev-parse branch1:P
produces a hash. That file is not in branch1
if you get an error message instead. The existence of path P
in your index or work-tree is not relevant when answering this particular question. Thus, the secret here is to examine the result of git rev-parse
on each branch-name:path
. This either fails because the file is "in" at most one branch, or gives us two hash IDs. If the two hash IDs are the same, the file is the same in both branches. No changing is required. If the hash IDs differ, the file is different in the two branches, and must be changed to switch branches.
The key notion here is that files in commits are frozen forever. Files you will edit are obviously not frozen. We are, at least initially, looking only at the mismatches between two frozen commits. Unfortunately, we—or Git—also have to deal with files that aren't in the commit you're going to switch away from and are in the commit you're going to switch to. This leads to the remaining complications, since files can also exist in the index and/or in the work-tree, without having to exist these two particular frozen commits we're working with.
2It might be considered "sort-of-safe" if it already exists with the "right contents", so that Git does not have to create it after all. I recall at least some versions of Git allowing this, but testing just now shows it to be considered "unsafe" in Git 1.8.5.4. The same argument would apply to a modified file that happens to be modified to match the to-be-switch-to branch. Again, 1.8.5.4 just says "would be overwritten", though. See the end of the technical notes as well: my memory may be faulty as I don't think the read-tree rules have changed since I first started using Git at version 1.5.something.
Yes, in some ways. In particular, you can stage a change, then "de-modify" the work tree file. Here's a file in two branches, that's different in branch1
and branch2
:
$ git show branch1:inboth
this file is in both branches
$ git show branch2:inboth
this file is in both branches
but it has more stuff in branch2 now
$ git checkout branch1
Switched to branch 'branch1'
$ echo 'but it has more stuff in branch2 now' >> inboth
At this point, the working tree file inboth
matches the one in branch2
, even though we're on branch1
. This change is not staged for commit, which is what git status --short
shows here:
$ git status --short
M inboth
The space-then-M means "modified but not staged" (or more precisely, working-tree copy differs from staged/index copy).
$ git checkout branch2
error: Your local changes ...
OK, now let's stage the working-tree copy, which we already know also matches the copy in branch2
.
$ git add inboth
$ git status --short
M inboth
$ git checkout branch2
Switched to branch 'branch2'
Here the staged-and-working copies both matched what was in branch2
, so the checkout was allowed.
Let's try another step:
$ git checkout branch1
Switched to branch 'branch1'
$ cat inboth
this file is in both branches
The change I made is lost from the staging area now (because checkout writes through the staging area). This is a bit of a corner case. The change is not gone, but the fact that I had staged it, is gone.
Let's stage a third variant of the file, different from either branch-copy, then set the working copy to match the current branch version:
$ echo 'staged version different from all' > inboth
$ git add inboth
$ git show branch1:inboth > inboth
$ git status --short
MM inboth
The two M
s here mean: staged file differs from HEAD
file, and, working-tree file differs from staged file. The working-tree version does match the branch1
(aka HEAD
) version:
$ git diff HEAD
$
But git checkout
won't allow the checkout:
$ git checkout branch2
error: Your local changes ...
Let's set the branch2
version as the working version:
$ git show branch2:inboth > inboth
$ git status --short
MM inboth
$ git diff HEAD
diff --git a/inboth b/inboth
index ecb07f7..aee20fb 100644
--- a/inboth
+++ b/inboth
@@ -1 +1,2 @@
this file is in both branches
+but it has more stuff in branch2 now
$ git diff branch2 -- inboth
$ git checkout branch2
error: Your local changes ...
Even though the current working copy matches the one in branch2
, the staged file does not, so a git checkout
would lose that copy, and the git checkout
is rejected.
The underlying implementation mechanism for all of this is Git's index. The index, also called the "staging area", is where you build the next commit: it starts out matching the current commit, i.e., whatever you have checked-out now, and then each time you git add
a file, you replace the index version with whatever you have in your work-tree.
Remember, the work-tree is where you work on your files. Here, they have their normal form, rather than some special only-useful-to-Git form like they do in commits and in the index. So you extract a file from a commit, through the index, and then on into the work-tree. After changing it, you git add
it to the index. So there are in fact three places for each file: the current commit, the index, and the work-tree.
When you run git checkout branch2
, what Git does underneath the covers is to compare the tip commit of branch2
to whatever is in both the current commit and the index now. Any file that matches what's there now, Git can leave alone. It's all untouched. Any file that's the same in both commits, Git can also leave alone—and these are the ones that let you switch branches.
Much of Git, including commit-switching, is relatively fast because of this index. What's actually in the index is not each file itself, but rather each file's hash. The copy of the file itself is stored as what Git calls a blob object, in the repository. This is similar to how the files are stored in commits as well: commits don't actually contain the files, they just lead Git to the hash ID of each file. So Git can compare hash IDs—currently 160-bit-long strings—to decide if commits X and Y have the same file or not. It can then compare those hash IDs to the hash ID in the index, too.
This is what leads to all the oddball corner cases above. We have commits X and Y that both have file path/to/name.txt
, and we have an index entry for path/to/name.txt
. Maybe all three hashes match. Maybe two of them match and one doesn't. Maybe all three are different. And, we might also have another/file.txt
that's only in X or only in Y and is or is not in the index now. Each of these various cases requires its own separate consideration: does Git need to copy the file out from commit to index, or remove it from index, to switch from X to Y? If so, it also has to copy the file to the work-tree, or remove it from the work-tree. And if that's the case, the index and work-tree versions had better match at least one of the committed versions; otherwise Git will be clobbering some data.
(The complete rules for all of this are described in, not the git checkout
documentation as you might expect, but rather the git read-tree
documentation, under the section titled "Two Tree Merge".)
if you don't like the double brackets or you don't want to write a function, you can just use a variable.
$path = Test-Path C:\Code
if (!$path) {
write "it doesn't exist!"
}
For what purpose is this function useful?
One particular usage is counting with a dictionary. Let's assume you want to count the number of occurrences of each element in a given list. The common way to do so is to make a dictionary where keys are elements and values are the number of occurrences.
fruits = ['apple', 'banana', 'peach', 'apple', 'pear']
d = {}
for fruit in fruits:
if fruit not in d:
d[fruit] = 0
d[fruit] += 1
Using the .get()
method, you can make this code more compact and clear:
for fruit in fruits:
d[fruit] = d.get(fruit, 0) + 1
You could also use deconstruction and tuples and try something like this:
@foreach (var (index, member) in @Model.Members.Select((member, i) => (i, member)))
{
<div>@index - @member.anyProperty</div>
if(index > 0 && index % 4 == 0) { // display clear div every 4 elements
@: <div class="clear"></div>
}
}

Listen , Make Following changes in your code if you want to show empty datetimepicker and get null when no date is selected by user, else save date.
if user will interact with datetimepicker its VALUECHANGED event will be called and there set its TAG property to 1.
Now when saving, check if its TAG is zero, then save NULL date else if TAG is 1 then pick and save Datetime picker value.
It Works like a charm.
Now if you want its value be changed back to empty by user interaction, then add checkbox and show text "Clear" with this checkbox. if user wants to clear date, simply again set its CUSTOM FORMAT property to empty string " ", and set its TAG back to 0. Thats it..
I do the following for my .NET Standard 2.0 projects.
Create a Directory.Build.props
file (e.g. in the root of your repo)
and move the properties to be shared from the .csproj
file to this file.
MSBuild will pick it up automatically and apply them to the autogenerated AssemblyInfo.cs
.
They also get applied to the nuget package when building one with dotnet pack
or via the UI in Visual Studio 2017.
See https://docs.microsoft.com/en-us/visualstudio/msbuild/customize-your-build
Example:
<Project>
<PropertyGroup>
<Company>Some company</Company>
<Copyright>Copyright © 2020</Copyright>
<AssemblyVersion>1.0.0.1</AssemblyVersion>
<FileVersion>1.0.0.1</FileVersion>
<Version>1.0.0.1</Version>
<!-- ... -->

In my case, I had generated DbContext from an existing database. I had my connection string set in appSettings.json
file; however, when I generated the class files by scaffolding the DbContext class it had incorrect connection string.
So make sure your connection string is proper in appSettings.json
file as well as in DbContext
file. This will solve your issue.
I spent half a day with this problem. The reason was that be sure to check where the volume was recorded.

But the fact is that in this place was the code that we changed. But when updating the docker, the code did not change.
Therefore, if you are checking someone else's code and for some reason you are not updating, check this.
And so in general this approach works:
docker-compose down
docker-compose build
docker-compose up -d
IETF has suggested jose libs on it's wiki: http://trac.tools.ietf.org/wg/jose/trac/wiki
I would highly recommend using them for signing. I am not a Java guy, but seems like jose4j seems like a good option. Has nice examples as well: https://bitbucket.org/b_c/jose4j/wiki/JWS%20Examples
Update: jwt.io provides a neat comparison of several jwt related libraries, and their features. A must check!

This solution merges smoothly and does not lose history:
jQuery offers $.inArray
:
Note that inArray returns the index of the element found, so 0
indicates the element is the first in the array. -1
indicates the element was not found.
var categoriesPresent = ['word', 'word', 'specialword', 'word'];_x000D_
var categoriesNotPresent = ['word', 'word', 'word'];_x000D_
_x000D_
var foundPresent = $.inArray('specialword', categoriesPresent) > -1;_x000D_
var foundNotPresent = $.inArray('specialword', categoriesNotPresent) > -1;_x000D_
_x000D_
console.log(foundPresent, foundNotPresent); // true false
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
_x000D_
Edit 3.5 years later
$.inArray
is effectively a wrapper for Array.prototype.indexOf
in browsers that support it (almost all of them these days), while providing a shim in those that don't. It is essentially equivalent to adding a shim to Array.prototype
, which is a more idiomatic/JSish way of doing things. MDN provides such code. These days I would take this option, rather than using the jQuery wrapper.
var categoriesPresent = ['word', 'word', 'specialword', 'word'];_x000D_
var categoriesNotPresent = ['word', 'word', 'word'];_x000D_
_x000D_
var foundPresent = categoriesPresent.indexOf('specialword') > -1;_x000D_
var foundNotPresent = categoriesNotPresent.indexOf('specialword') > -1;_x000D_
_x000D_
console.log(foundPresent, foundNotPresent); // true false
_x000D_
Edit another 3 years later
Gosh, 6.5 years?!
The best option for this in modern Javascript is Array.prototype.includes
:
var found = categories.includes('specialword');
No comparisons and no confusing -1
results. It does what we want: it returns true
or false
. For older browsers it's polyfillable using the code at MDN.
var categoriesPresent = ['word', 'word', 'specialword', 'word'];_x000D_
var categoriesNotPresent = ['word', 'word', 'word'];_x000D_
_x000D_
var foundPresent = categoriesPresent.includes('specialword');_x000D_
var foundNotPresent = categoriesNotPresent.includes('specialword');_x000D_
_x000D_
console.log(foundPresent, foundNotPresent); // true false

To get a list of tables for the current database in DB2 -->
Connect to the database:
db2 connect to DATABASENAME user USER using PASSWORD
Run this query:
db2 LIST TABLES
This is the equivalent of SHOW TABLES in MySQL.
You may need to execute 'set schema myschema' to the correct schema before you run the list tables command. By default upon login your schema is the same as your username - which often won't contain any tables. You can use 'values current schema' to check what schema you're currently set to.
Change the checkboxes so that the name includes the index inside the brackets:
<input type="checkbox" class="checkbox_veh" id="checkbox_addveh<?php echo $i; ?>" <?php if ($vehicle_feature[$i]->check) echo "checked"; ?> name="feature[<?php echo $i; ?>]" value="<?php echo $vehicle_feature[$i]->id; ?>">
The checkboxes that aren't checked are never submitted. The boxes that are checked get submitted, but they get numbered consecutively from 0, and won't have the same indexes as the other corresponding input fields.
Try to edit your my.cf and comment the original sql_mode and add sql_mode = "".

String cd="Holding some value";
Converting from string to byte[]:
byte[] cookie = new sun.misc.BASE64Decoder().decodeBuffer(cd);
Converting from byte[] to string:
cd = new sun.misc.BASE64Encoder().encode(cookie);
You can also use a proxy tool like Charles to capture the outgoing request headers, data, etc. by passing the proxy details through CURLOPT_PROXY
to your curl_setopt_array
method.
For example:
$proxy = '127.0.0.1:8888';
$opt = array (
CURLOPT_URL => "http://www.example.com",
CURLOPT_PROXY => $proxy,
CURLOPT_POST => true,
CURLOPT_VERBOSE => true,
);
$ch = curl_init();
curl_setopt_array($ch, $opt);
curl_exec($ch);
curl_close($ch);
Default is:
Username: root
Password: [null]
The Password is set to 'password' in some versions.
After spending about two hours trying to come up with a solution I realized that I had adblockers blocking the call to GA. Once I turned them off I was good to go.
$this->db->where('emailsToCampaigns.campaignId !=' , $campaignId);
This should work (which you have tried)
To debug you might place this code just after you execute your query to see what exact SQL it is producing, this might give you clues, you might add that to the question to allow for further help.
$this->db->get(); // your query executing
echo '<pre>'; // to preserve formatting
die($this->db->last_query()); // halt execution and print last ran query.
You can use this regex to get the yyyy-MM-dd format:
((?:19|20)\\d\\d)-(0?[1-9]|1[012])-([12][0-9]|3[01]|0?[1-9])

I looked at my Environment Variables and had a System Variable called _JAVA_OPTIONS
with the value -Xms256m -Xmx512m

If you want to place the cursor in a certain position on an EditText, you can use:
yourEditText.setSelection(position);
Additionally, there is the possibility to set the initial and final position, so that you programmatically select some text, this way:
yourEditText.setSelection(startPosition, endPosition);
Please note that setting the selection might be tricky since you can place the cursor before or after a character, the image below explains how to index works in this case:
So, if you want the cursor at the end of the text, just set it to yourEditText.length()
.
You can also try getting the element's onclick attribute and then passing into eval. This should work despite the big taboo over eval. I put a sample below
eval(document.getElementById('elementId').getAttribute('onclick'));
Assuming the image data is already in the format you want, you don't need image ImageIO
at all - you just need to write the data to the file:
// Note preferred way of declaring an array variable
byte[] data = Base64.decodeBase64(crntImage);
try (OutputStream stream = new FileOutputStream("c:/decode/abc.bmp")) {
stream.write(data);
}
(I'm assuming you're using Java 7 here - if not, you'll need to write a manual try/finally statement to close the stream.)
If the image data isn't in the format you want, you'll need to give more details.
Your regex is good altough I would replace it with the empty string
String resultString = subjectString.replaceAll("[\t\n\r]", "");
You expect a space between "text." and "And" right?
I get that space when I try the regex by copying your sample
"This is my text. "
So all is well here. Maybe if you just replace it with the empty string it will work. I don't know why you replace it with \s. And the alternation | is not necessary in a character class.
Is there a good reason not to use a hash? Lookups are O(1)
vs. O(n)
for the array.

I was getting this error, and determined it was actually on a field that was not hidden.
In this case, it was a type="number"
field, that is required. When no value has ever been entered into this field, the error message is shown in the console, and the form is not submitted. Entering a value, and then removing it means that the validation error is shown as expected.
I believe this is a bug in Chrome: my workaround for now was to come up with an initial/default value.
I wasn't satisfied with the rounded top and bottom to the shadow present in Deefour's solution so created my own.
inset
box-shadow
creates a nice uniform shadow with the top and bottom cut off.
To use this effect on the sides of your element, create two pseudo elements :before
and :after
positioned absolutely on the sides of the original element.
div:before, div:after {
content: " ";
height: 100%;
position: absolute;
top: 0;
width: 15px;
}
div:before {
box-shadow: -15px 0 15px -15px inset;
left: -15px;
}
div:after {
box-shadow: 15px 0 15px -15px inset;
right: -15px;
}
div {
background: #EEEEEE;
height: 100px;
margin: 0 50px;
width: 100px;
position: relative;
}
_x000D_
<div></div>
_x000D_
Edit
Depending on your design, you may be able to use clip-path
, as shown in @Luke's answer. However, note that in many cases this still results in the shadow tapering off at the top and bottom as you can see in this example:
div {
width: 100px;
height: 100px;
background: #EEE;
box-shadow: 0 0 15px 0px #000;
clip-path: inset(0px -15px 0px -15px);
position: relative;
margin: 0 50px;
}

First thing to do: Check for the PHP version your machine is running.
Command Line: php -version
This will show something like this (in my case):
PHP 7.0.8-0ubuntu0.16.04.3 (cli) ( NTS ) Copyright (c) 1997-2016 The PHP Group
If you are using PHP 5.x.x => run command: sudo apt-get install php5-curl
If PHP 7.x.x => run command (in my case): sudo apt-get install php7.0-curl
Enable this extension by running:
sudo gedit /etc/php/7.0/cli/php.ini
And in the file "php.ini" search for keyword "curl" to find this line below and change it from
;extension=php_curl.dll
To:
extension=php_curl.dll
Next, save your file "php.ini".
Finally, in your command line, restart your server by running: sudo service apache2 restart
.
We just released an experimental GitHub repository which should ease the process of using NVIDIA GPUs inside Docker containers.
Your curl gets timed out. Probably the url you are trying that requires more that 30 seconds.
If you are running the script through browser, then set the set_time_limit
to zero for infinite seconds.
set_time_limit(0);
Increase the curl's operation time limit using this option CURLOPT_TIMEOUT
curl_setopt($ch, CURLOPT_TIMEOUT,500); // 500 seconds
It can also happen for infinite redirection from the server. To halt this try to run the script with follow location disabled.
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
You can use browscap-java to get browser's information.
For Example:
UserAgentParser parser = new UserAgentService().loadParser(Arrays.asList(BrowsCapField.BROWSER));
Capabilities capabilities = parser.parse(user_agent);
String browser = capabilities.getBrowser();
By default verbose = 1,
verbose = 1, which includes both progress bar and one line per epoch
verbose = 0, means silent
verbose = 2, one line per epoch i.e. epoch no./total no. of epochs
Try this:
@Html.DropDownList(
"country",
new[] {
new SelectListItem() { Value = "IN", Text = "India" },
new SelectListItem() { Value = "US", Text = "United States" }
},
"Country",
new { @class = "form-control",@selected = Model.Country}
)
How about nan_to_num()?
Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error()
and curl_errno()
will contain further information in case of failure:
try {
$ch = curl_init();
// Check if initialization had gone wrong*
if ($ch === false) {
throw new Exception('failed to initialize');
}
curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt(/* ... */);
$content = curl_exec($ch);
// Check the return value of curl_exec(), too
if ($content === false) {
throw new Exception(curl_error($ch), curl_errno($ch));
}
/* Process $content here */
// Close curl handle
curl_close($ch);
} catch(Exception $e) {
trigger_error(sprintf(
'Curl failed with error #%d: %s',
$e->getCode(), $e->getMessage()),
E_USER_ERROR);
}
* The curl_init()
manual states:
Returns a cURL handle on success, FALSE on errors.
I've observed the function to return FALSE
when you're using its $url
parameter and the domain could not be resolved. If the parameter is unused, the function might never return FALSE
. Always check it anyways, though, since the manual doesn't clearly state what "errors" actually are.

The accepted answer is good, but if you are using it to get values from a textView in android, it would be good to check if the string is empty. If the string is empty it would throw an exception.
private String capitizeString(String name){
String captilizedString="";
if(!name.trim().equals("")){
captilizedString = name.substring(0,1).toUpperCase() + name.substring(1);
}
return captilizedString;
}

I am not sure that the issue is related to what header php is sending. Make sure that the buffering is enabled. The simple way is to create a proxy.conf file:
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 100m;
client_body_buffer_size 128k;
proxy_connect_timeout 90;
proxy_send_timeout 90;
proxy_read_timeout 90;
proxy_buffering on;
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
And a fascgi.conf file:
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_buffers 128 4096k;
fastcgi_buffer_size 4096k;
fastcgi_index index.php;
fastcgi_param REDIRECT_STATUS 200;
Next you need to call them in your default config server this way:
http {
include /etc/nginx/mime.types;
include /etc/nginx/proxy.conf;
include /etc/nginx/fastcgi.conf;
index index.html index.htm index.php;
log_format main '$remote_addr - $remote_user [$time_local] $status '
'"$request" $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
#access_log /logs/access.log main;
sendfile on;
tcp_nopush on;
# ........
}
If you wont to forward your ref
, in Props interface you need to use RefObject<CmpType>
type from import React, { RefObject } from 'react';

I took a long look at many questions like this, and found this post... I didn't like the fact that the conversion code is duplicated for each type, so I've made a generic method to perform the task:
public static byte[] toByteArray(long value, int n)
{
byte[] ret = new byte[n];
ret[n-1] = (byte) ((value >> (0*8) & 0xFF);
ret[n-2] = (byte) ((value >> (1*8) & 0xFF);
...
ret[1] = (byte) ((value >> ((n-2)*8) & 0xFF);
ret[0] = (byte) ((value >> ((n-1)*8) & 0xFF);
return ret;
}
See full post.
I don't see any reason why it would be a bad practice PROVIDED that you want to complete STOP processing at that point.
pydantic is an increasingly popular library for python 3.6+ projects. It mainly does data validation and settings management using type hints.
A basic example using different types:
from pydantic import BaseModel
class ClassicBar(BaseModel):
count_drinks: int
is_open: bool
data = {'count_drinks': '226', 'is_open': 'False'}
cb = ClassicBar(**data)
>>> cb
ClassicBar(count_drinks=226, is_open=False)
What I love about the lib is that you get a lot of goodies for free, like
>>> cb.json()
'{"count_drinks": 226, "is_open": false}'
>>> cb.dict()
{'count_drinks': 226, 'is_open': False}
I was looking for the right method to handle those radio buttons here is an example for a solution I found here:
<tr *ngFor="let entry of entries">
<td>{{ entry.description }}</td>
<td>
<input type="radio" name="radiogroup"
[value]="entry.id"
(change)="onSelectionChange(entry)">
</td>
</tr>
Notice the onSelectionChange that passes the current element to the method.
The default behavior of Selenium us to scroll so the element is barely in view at the top of the viewport. Also, not all browsers have the exact same behavior. This is very dis-satisfying. If you record videos of your browser tests, like I do, what you want is for the element to scroll into view and be vertically centered.
Here is my solution for Java:
public List<String> getBoundedRectangleOfElement(WebElement we)
{
JavascriptExecutor je = (JavascriptExecutor) driver;
List<String> bounds = (ArrayList<String>) je.executeScript(
"var rect = arguments[0].getBoundingClientRect();" +
"return [ '' + parseInt(rect.left), '' + parseInt(rect.top), '' + parseInt(rect.width), '' + parseInt(rect.height) ]", we);
System.out.println("top: " + bounds.get(1));
return bounds;
}
And then, to scroll, you call it like this:
public void scrollToElementAndCenterVertically(WebElement we)
{
List<String> bounds = getBoundedRectangleOfElement(we);
Long totalInnerPageHeight = getViewPortHeight(driver);
JavascriptExecutor je = (JavascriptExecutor) driver;
je.executeScript("window.scrollTo(0, " + (Integer.parseInt(bounds.get(1)) - (totalInnerPageHeight/2)) + ");");
je.executeScript("arguments[0].style.outline = \"thick solid #0000FF\";", we);
}

.ipa
is there!from ..subpkg2 import mod
Per the Python docs: When inside a package hierarchy, use two dots, as the import statement doc says:
When specifying what module to import you do not have to specify the absolute name of the module. When a module or package is contained within another package it is possible to make a relative import within the same top package without having to mention the package name. By using leading dots in the specified module or package after
from
you can specify how high to traverse up the current package hierarchy without specifying exact names. One leading dot means the current package where the module making the import exists. Two dots means up one package level. Three dots is up two levels, etc. So if you executefrom . import mod
from a module in thepkg
package then you will end up importingpkg.mod
. If you executefrom ..subpkg2 import mod
from withinpkg.subpkg1
you will importpkg.subpkg2.mod
. The specification for relative imports is contained within PEP 328.
PEP 328 deals with absolute/relative imports.
use this:
\password
enter the new password you want for that user and then confirm it. If you don't remember the password and you want to change it, you can log in as postgres and then use this:
ALTER USER 'the username' WITH PASSWORD 'the new password';
why not printf '%02d' $num
? See help printf
for this internal bash command.
if re.search(r"\b(?<=\w)%s\b(?!\w)" % TEXTO, subject, re.IGNORECASE):
This will insert what is in TEXTO into the regex as a string.
If you want "insert or replace" semantics, use this syntax:
A[key] = value; // <-- insert or replace semantics
It's more efficient and readable than calls involving "ContainsKey()" or "Remove()" prior to "Add()".
So in your case:
rct3Features[items[0]] = items[1];
I want to share how I did this. I spent the last few days rattling my head with how to pass a couple of parameters to the bootstrap modal dialog. After much head bashing, I came up with a rather simple way of doing this.
Here is my modal code:
<div class="modal fade" id="editGroupNameModal" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div id="editGroupName" class="modal-header">Enter new name for group </div>
<div class="modal-body">
<%= form_tag( { action: 'update_group', port: portnum } ) do %>
<%= text_field_tag( :gid, "", { type: "hidden" }) %>
<div class="input-group input-group-md">
<span class="input-group-addon" style="font-size: 16px; padding: 3;" >Name</span>
<%= text_field_tag( :gname, "", { placeholder: "New name goes here", class: "form-control", aria: {describedby: "basic-addon1"}}) %>
</div>
<div class="modal-footer">
<%= submit_tag("Submit") %>
</div>
<% end %>
</div>
</div>
</div>
</div>
And here is the simple javascript to change the gid, and gname input values:
function editGroupName(id, name) {
$('input#gid').val(id);
$('input#gname.form-control').val(name);
}
I just used the onclick event in a link:
// ' is single quote
// ('1', 'admin')
<a data-toggle="modal" data-target="#editGroupNameModal" onclick="editGroupName('1', 'admin'); return false;" href="#">edit</a>
The onclick fires first, changing the value property of the input boxes, so when the dialog pops up, values are in place for the form to submit.
I hope this helps someone someday. Cheers.
This may be a overwhelming problem if you use Auto layout because you can not directly manipulate frames anymore. There is a simple solution without too much work.
I ended up writing an utility method in an Utility Class and called it from all the view controllers's viewDidLayoutSubviews
Method.
+ (void)addStatusBarIfiOS7:(UIViewController *)vc
{
if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_6_1) {
CGRect viewFrame = vc.view.frame;
if(viewFrame.origin.y == 20) {
//If the view's y origin is already 20 then don't move it down.
return;
}
viewFrame.origin.y+=20.0;
viewFrame.size.height-= 20.0;
vc.view.frame = viewFrame;
[vc.view layoutIfNeeded];
}
}
Override your viewDidLayoutSubviews
method in the view controller, where you want status bar. It will get you through the burden of Autolayout.
- (void)viewDidLayoutSubviews
{
[[UIApplication sharedApplication]setStatusBarStyle:UIStatusBarStyleLightContent];
[super viewDidLayoutSubviews];
[MyUtilityClass addStatusBarIfiOS7:self];
}
Try this:
$('select option:selected').prop('label');
This will pull out the displayed text for both styles of <option>
elements:
<option label="foo"><option>
-> "foo"
<option>bar<option>
-> "bar"
If it has both a label
attribute and text inside the element, it'll use the label
attribute, which is the same behavior as the browser.
For posterity, this was tested under jQuery 3.1.1
As in Objective-C, you can't add stored property to existing classes. If you're extending an Objective-C class (UIView
is definitely one), you can still use Associated Objects to emulate stored properties:
for Swift 1
import ObjectiveC
private var xoAssociationKey: UInt8 = 0
extension UIView {
var xo: PFObject! {
get {
return objc_getAssociatedObject(self, &xoAssociationKey) as? PFObject
}
set(newValue) {
objc_setAssociatedObject(self, &xoAssociationKey, newValue, objc_AssociationPolicy(OBJC_ASSOCIATION_RETAIN))
}
}
}
The association key is a pointer that should be the unique for each association. For that, we create a private global variable and use it's memory address as the key with the &
operator. See the Using Swift with Cocoa and Objective-C
on more details how pointers are handled in Swift.
UPDATED for Swift 2 and 3
import ObjectiveC
private var xoAssociationKey: UInt8 = 0
extension UIView {
var xo: PFObject! {
get {
return objc_getAssociatedObject(self, &xoAssociationKey) as? PFObject
}
set(newValue) {
objc_setAssociatedObject(self, &xoAssociationKey, newValue, objc_AssociationPolicy.OBJC_ASSOCIATION_RETAIN)
}
}
}
UPDATED for Swift 4
In Swift 4, it's much more simple. The Holder struct will contain the private value that our computed property will expose to the world, giving the illusion of a stored property behaviour instead.
extension UIViewController {
struct Holder {
static var _myComputedProperty:Bool = false
}
var myComputedProperty:Bool {
get {
return Holder._myComputedProperty
}
set(newValue) {
Holder._myComputedProperty = newValue
}
}
}
<?php

$return = array_key_exists($key, $arr);
if($return == false){
break;
}
}
}
}
return $return;
}
//run demo

$array = array('a'=>'aaaa','b'=>'ccc','c'=>'eeeee');

I had this error because I was providing a string of arguments to subprocess.call
instead of an array of arguments. To prevent this, use shlex.split
:
import shlex, subprocess
command_line = "ls -a"
args = shlex.split(command_line)
p = subprocess.Popen(args)
There's a workaround to achieve it.
First, bind your iframe to a target page with relative url. The browsers will treat the site in iframe the same domain with your website.
In your web server, using a rewrite module to redirect request from the relative url to absolute url. If you use IIS, I recommend you check on IIRF module.
Straightforward and easy solution is:
docker build .
=> ....
=> Successfully built a3e628814c67
docker run -p 3000:3000 a3e628814c67
3000
- can be any port
a3e628814c68
- hash result given by success build command
NOTE: you should be within directory that contains Dockerfile.
String tokenizer this code should put you in the right direction.
int main(void) {
char st[] ="Where there is will, there is a way.";
char *ch;
ch = strtok(st, " ");
while (ch != NULL) {
printf("%s\n", ch);
ch = strtok(NULL, " ,");
}
getch();
return 0;
}
You need to use Arrow function ()=>
ES6 feature to preserve this
context within setTimeout
.
// var that = this; // no need of this line
this.messageSuccess = true;
setTimeout(()=>{ //<<<---using ()=> syntax
this.messageSuccess = false;
}, 3000);
The top answer here from Micah Hainline works great, but even better is the library that was built from it by user aleb as he posted in the comments under Micahs answer:
I created an Android library with this component and changed it to be able to show as many lines of text as possible and ellipsize the last one; see github.com/triposo/barone
There are some more features to it, if you only need the TextView, it is here.
Maybe this will help others find it faster than I did :-)
Use a DecimalFormatter:
double number = 0.9999999999999;
DecimalFormat numberFormat = new DecimalFormat("#.00");
System.out.println(numberFormat.format(number));
Will give you "0.99". You can add or subtract 0 on the right side to get more or less decimals.
Or use '#' on the right to make the additional digits optional, as in with #.## (0.30) would drop the trailing 0 to become (0.3).
I believe GUIDs are constrained to 16-byte lengths (or 32 bytes for an ASCII hex equivalent).
I had this problem because I had a typo in my template near [(ngModel)]]. Extra bracket. Example:
<input id="descr" name="descr" type="text" required class="form-control width-half"
[ngClass]="{'is-invalid': descr.dirty && !descr.valid}" maxlength="16" [(ngModel)]]="category.descr"
[disabled]="isDescrReadOnly" #descr="ngModel">

You should use a SQL tool to visualize possbile errors like MySQL Workbench.
For me it was because they are not in the same namespace. After I remove my AppStart from "project.Startup.AppStart" and let they both Startup.cs and Startup.Auth.cs with "project.Startup" namespace, everything was back to work perfectly.
I hope it help!
You can do it in one sql statement for existing customers, 3 statements for new ones. All you have to do is be an optimist and act as though the customer already exists:
insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);
If the customer does not exist, you'll get an sql exception which text will be something like:
null value in column "customer_id" violates not-null constraint
(providing you made customer_id non-nullable, which I'm sure you did). When that exception occurs, insert the customer into the customer table and redo the insert into the order table:
insert into customer(name) values ('John');
insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);
Unless your business is growing at a rate that will make "where to put all the money" your only real problem, most of your inserts will be for existing customers. So, most of the time, the exception won't occur and you'll be done in one statement.
For those looking for a Kotlin version, you can use something like this;
private fun telephonyService() {
val telephonyManager = getSystemService(TELEPHONY_SERVICE) as TelephonyManager
val imei = if (android.os.Build.VERSION.SDK_INT >= 26) {
Timber.i("Phone >= 26 IMEI")
telephonyManager.imei
} else {
Timber.i("Phone IMEI < 26")
telephonyManager.deviceId
}
Timber.i("Phone IMEI $imei")
}
NOTE: You must wrap telephonyService()
above with a permission check using checkSelfPermission or whatever method you use.
Also add this permission in the manifest file;
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
The Set statement is only used for object variables (like Range
, Cell
or Worksheet
in Excel), while the simple equal sign '=' is used for elementary datatypes like Integer
. You can find a good explanation for when to use set here.
The other problem is, that your variable g1val
isn't actually declared as Integer
, but has the type Variant
. This is because the Dim statement doesn't work the way you would expect it, here (see example below). The variable has to be followed by its type right away, otherwise its type will default to Variant
. You can only shorten your Dim statement this way:
Dim intColumn As Integer, intRow As Integer 'This creates two integers
For this reason, you will see the "Empty" instead of the expected "0" in the Watches window.
Try this example to understand the difference:
Sub Dimming()
Dim thisBecomesVariant, thisIsAnInteger As Integer
Dim integerOne As Integer, integerTwo As Integer
MsgBox TypeName(thisBecomesVariant) 'Will display "Empty"
MsgBox TypeName(thisIsAnInteger ) 'Will display "Integer"
MsgBox TypeName(integerOne ) 'Will display "Integer"
MsgBox TypeName(integerTwo ) 'Will display "Integer"
'By assigning an Integer value to a Variant it becomes Integer, too
thisBecomesVariant = 0
MsgBox TypeName(thisBecomesVariant) 'Will display "Integer"
End Sub
Two further notices on your code:
First remark: Instead of writing
'If g1val is bigger than the value in the current cell
If g1val > Cells(33, i).Value Then
g1val = g1val 'Don't change g1val
Else
g1val = Cells(33, i).Value 'Otherwise set g1val to the cell's value
End If
you could simply write
'If g1val is smaller or equal than the value in the current cell
If g1val <= Cells(33, i).Value Then
g1val = Cells(33, i).Value 'Set g1val to the cell's value
End If
Since you don't want to change g1val
in the other case.
Second remark: I encourage you to use Option Explicit when programming, to prevent typos in your program. You will then have to declare all variables and the compiler will give you a warning if a variable is unknown.
This worked for me:
try this. There are in general three ways to use mysqldump—
in order to dump a set of one or more tables,
shell> mysqldump [options] db_name [tbl_name ...]
a set of one or more complete databases
shell> mysqldump [options] --databases db_name ...
or an entire MySQL server—as shown here:
shell> mysqldump [options] --all-databases
