Add this line to your floated element selector
.floated {
float: left;
...
box-sizing: border-box;
}
It will prevent padding and borders to be added to width, so element always stay in row, even if you have eg. three elements with width of 33.33333%
Originally, callback were used for asynchronous operations (e.g. in the XMLHttpRequest API). Now promise-based APIs like the browser's Fetch API have become the default solution and the nicer async/await
syntax is supported by all modern browsers and on Node.Js (server side).
A common scenario - fetching JSON data from the server - can look like this:
async function fetchResource(url) {
const res = await fetch(url);
if (!res.ok) {
throw new Error(res.statusText);
}
return res.json();
}
To use it in another function:
async function doSomething() {
try {
const data = await fetchResource("https://example.test/resource/1");
// ...
} catch (e) {
// handle error
...
}
}
If you design a modern API, it is strongly recommended to prefer promise-based style over callbacks. If you inherited an API that relies on callbacks, it is possible to wrap it as a promise:
function sleep(timeout) {
return new Promise((resolve) => {
setTimeout(() => {
resolve();
}, timeout);
});
}
async function fetchAfterTwoSeconds(url) {
await sleep(2000);
return fetchResource(url);
}
In Node.Js, which historically relied exclusively on callbacks, that technique is so common that they added a helper function called util.promisify
.
before the position where repetitive objects begin , you should close the session and then you should start a new session
session.close();
session = HibernateUtil.getSessionFactory().openSession();
so in this way in one session there is not more than one entities that have the same identifier.
finalName is created as:
<build>
<finalName>${project.artifactId}-${project.version}</finalName>
</build>
One of the solutions is to add own property:
<properties>
<finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
<finalName>${finalName}</finalName>
</build>
And now try:
mvn -DfinalName=build clean package
Download it from here:
http://www.iis.net/downloads/microsoft/url-rewrite
or if you already have Web Platform Installer on your machine you can install it from there.
Ok, it's actually simple. Assuming that your macro is in a module,not in one of the sheets, you use:
objExcel.Application.Run "test.xls!dog"
'notice the format of 'workbook name'!macro
For a filename with spaces, encase the filename with quotes.
If you've placed the macro under a sheet, say sheet1, just assume sheet1 owns the function, which it does.
objExcel.Application.Run "'test 2.xls'!sheet1.dog"
Notice: You don't need the macro.testfunction notation you've been using.
Well, I would like to add my 2 cents here.
I'm using shared webhosting and I tackled this problem many times, tried to resolve it on my own but to no avail.
Finally I managed to resolve it through checking various web sources and contacting my hosting service provider. My questions were "How can I change php value memory_limit
in shared webhosting?", "How can I change php value upload_max_filesize
in shared webhosting?", "How can I change php value max_input_vars
in shared webhosting?", "How can I change php value max_execution_time
in shared webhosting?", "How can I change php value max_input_time
in shared webhosting?" and many more by configuring or changing php.ini or .htaccess
file. I tried to change them but problems arose. Finally I contacted my hosting provider, and it turns out that I set my php to native, they changed it to php 5.6, here is their answer:
"Your PHP was set to 'native' mode which means you can't override those values. I've changed you to just '5.6' so you should be good to go."
After that I connected my website through ftp Filezilla, also don't forget to make both your ftp service to show hidden files, and your local computer to do so, because .htaccess
file was hidden in my local laptop and in my website. It was available in public_html folder, I just downloaded it and added the following codes to the end of the file and then uploaded it back to the server:
php_value memory_limit 256M
php_value post_max_size 256M
php_value upload_max_filesize 64M
php_value max_input_vars 1800
php_value max_execution_time 300
php_value max_input_time 300
Everything is working properly for the time being, if any of you overcome with some problems please write here and warn me so that I can change the above-shown codes. By the way, I also upload some pictures which shows the change.
One more thing I almost forgot to mention ZipArchive installation on your shared webhosting service, I managed that requirement to tick by just going to php settings through my cpanel, click on php selector extensions and then tick zip section, that's all.
Thanks.
PS: I'm open to good practices, and if you see any bad practice here please let me know, I'll try to change them. Thanks.
Simple Solution from ascending to descending and vice versa is:
STRINGS
str = ['ravi', 'aravind', 'joker', 'poker']
asc_string = str.sort # => ["aravind", "joker", "poker", "ravi"]
asc_string.reverse # => ["ravi", "poker", "joker", "aravind"]
DIGITS
digit = [234,45,1,5,78,45,34,9]
asc_digit = digit.sort # => [1, 5, 9, 34, 45, 45, 78, 234]
asc_digit.reverse # => [234, 78, 45, 45, 34, 9, 5, 1]
For the same solution I was looking for Angularjs directive with ng-Model
.
Here is the code that resolve the problem.
myApp.directive('zipcodeformatter', function () {
return {
restrict: 'A', // only activate on element attribute
require: '?ngModel', // get a hold of NgModelController
link: function (scope, element, attrs, ngModel) {
scope.$watch(attrs.ngModel, function (v) {
if (v) {
console.log('value changed, new value is: ' + v + ' ' + v.length);
if (v.length > 5) {
var newzip = v.replace("-", '');
var str = newzip.substring(0, 5) + '-' + newzip.substring(5, newzip.length);
element.val(str);
} else {
element.val(v);
}
}
});
}
};
});

Apart from the previous use cases, you can also use Docker Compose to create directories in case you want to make new dummy folders on docker-compose up
:
volumes:
- .:/ftp/
- /ftp/node_modules
- /ftp/files
Its simple, just make sure the data type in your columns are the same. For e.g. I faced the same error, that and an another error:
Error in
contrasts<-
(*tmp*
, value = contr.funs[1 + isOF[nn]]) : contrasts can be applied only to factors with 2 or more levels
So, I went back to my excel file or csv file, set a filter on the variable throwing me an error and checked if the distinct datatypes are the same. And... Oh! it had numbers and strings, so I converted numbers to string and it worked just fine for me.
Eclipse used to need a column mode plugin to be able to select a rectangular selection.
Since Eclipse 3.5, you just need to type Alt+Shift+A: see its News and Noteworthy section. (On OS X it's Option-Command-A.)
Or activate the '
Editor Presentation
' action set ( Window > Customize Perspective menu) to get a tool bar button for toggling the block selection mode.
AmbroseChapel adds in the comments:
This is a toggle.
Columnar selection is a mode you enter and leave: in other words, Eclipse switches into a mode where all mouse selections have to be columnar and you stay in that mode until you switch back (by using the same command again).
It's not like other editors where columnar selections are enabled only while certain keys are down.
I had this issue so I just took all my content, copy/pasted it into notepad, made a new php file, pasted back in, re-saved and overwrote, and.. that worked! It really was some relic of Microsoft Word editing...
var
variables still have a type - and the compiler error message says this type must be established during the declaration.
The specific request (assigning an initial null value) can be done, but I don't recommend it. It doesn't provide an advantage here (as the type must still be specified) and it could be viewed as making the code less readable:
var x = (String)null;
Which is still "type inferred" and equivalent to:
String x = null;
The compiler will not accept var x = null
because it doesn't associate the null with any type - not even Object. Using the above approach, var x = (Object)null
would "work" although it is of questionable usefulness.
Generally, when I can't use var
's type inference correctly then
The second approach can be done by moving code into methods or functions.
Try using this command. See the example given below:
df.loc[len(df)] = ['Product 9',99,9.99,8.88,1.11]
df
I found an easy resolution for this issue was to add source /etc/profile to the top of the script.sh file I was trying to run on the target system. On the systems here, this caused the environmental variables which were needed by script.sh to be configured as if running from a login shell.
In one of the prior responses it was suggested that ~/.bashr_profile etc... be used. I didn't spend much time on this but, the problem with this is if you ssh to a different user on the target system than the shell on the source system from which you log in it appeared to me that this causes the source system user name to be used for the ~.
I would recommend using Git Graph extension.
If you want to select only one of two nodes with union operator, you can use this solution:
(//bookstore/book/title | //bookstore/city/zipcode/title)[1]
I found this one more helpful and simple
DECLARE @StartTime datetime,@EndTime datetime
SELECT @StartTime=GETDATE()
--Your Query to be run goes here--
SELECT @EndTime=GETDATE()
SELECT DATEDIFF(ms,@StartTime,@EndTime) AS [Duration in milliseconds]
By default, git will update execute file permissions if you change them. It will not change or track any other permissions.
If you don't see any changes when modifying execute permission, you probably have a configuration in git which ignore file mode.
Look into your project, in the .git
folder for the config
file and you should see something like this:
[core]
filemode = false
You can either change it to true
in your favorite text editor, or run:
git config core.filemode true
Then, you should be able to commit normally your files. It will only commit the permission changes.
Well ya you can do that in this way.
<input type="text" name="address" id="address">
<div id="map_canvas" style="width: 500px; height: 300px"></div>
<input type="button" onclick="showAddress(address.value)" value="ShowMap"/>
Java Script
function showAddress(address){
alert("This is address :"+address)
}
That is one example for the same. and that will run.
You can use T-Regx library, that doesn't need delimiters
pattern('^([0-9]+)$')->match($input);
Valid numbers for ports are: 0 to 2^16-1 = 0 to 65535
That is because a port number is 16 bit length.
However ports are divided into:
Well-known ports: 0 to 1023 (used for system services e.g. HTTP, FTP, SSH, DHCP ...)
Registered/user ports: 1024 to 49151 (you can use it for your server, but be careful some famous applications: like Microsoft SQL Server database management system (MSSQL) server or Apache Derby Network Server are already taking from this range i.e. it is not recommended to assign the port of MSSQL to your server otherwise if MSSQL is running then your server most probably will not run because of port conflict )
Dynamic/private ports: 49152 to 65535. (not used for the servers rather the clients e.g. in NATing service)
In programming you can use any numbers 0 to 65535 for your server, however you should stick to the ranges mentioned above, otherwise some system services or some applications will not run because of port conflict.
Check the list of most ports here: https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers
DataRow's are nice in the way that they have their underlying table linked to them. With the underlying table you can verify that a specific row has a specific column in it.
If DataRow.Table.Columns.Contains("column") Then
MsgBox("YAY")
End If
To typecast in python use the constructor funtions of the type, passing the string (or whatever value you are trying to cast) as a parameter.
For example:
>>>float("23.333")
23.333
Behind the scenes, python is calling the objects __float__
method, which should return a float representation of the parameter. This is especially powerful, as you can define your own types (using classes) with a __float__
method so that it can be casted into a float using float(myobject).
A simple solution for a delayed auto submit:
<body onload="setTimeout(function() { document.frm1.submit() }, 5000)">
<form action="https://www.google.com" name="frm1">
<input type="hidden" name="q" value="Hello world" />
</form>
</body>
If I am to define the same proptypes for a particular shape multiple times, I like abstract it out to a proptypes file so that if the shape of the object changes, I only have to change the code in one place. It helps dry up the codebase a bit.
Example:
// Inside my proptypes.js file
import PT from 'prop-types';
export const product = {
id: PT.number.isRequired,
title: PT.string.isRequired,
sku: PT.string.isRequired,
description: PT.string.isRequired,
};
// Inside my component file
import PT from 'prop-types';
import { product } from './proptypes;
List.propTypes = {
productList: PT.arrayOf(product)
}
Write a simple server python server listening on a port (say 8080), bind the port -p 8080:8080 with the container, make a HTTP request to localhost:8080 to ask the python server running shell scripts with popen, run a curl or writing code to make a HTTP request curl -d '{"foo":"bar"}' localhost:8080

To really get this clear, here's my for-beginners answer:
You inputed the arguments in the wrong order.
A keyword argument has this style:
nullable=True, unique=False
A fixed parameter should be defined: True, False, etc. A non-keyword argument is different:
name="Ricardo", fruit="chontaduro"
This syntax error asks you to first put name="Ricardo"
and all of its kind (non-keyword) before those like nullable=True.
On Mac OS X, neither of these regex syntaxes work inside sed for matching whole words
\bmyWord\b
\<myWord\>
Hear me now and believe me later, this ugly syntax is what you need to use:
/[[:<:]]myWord[[:>:]]/
So, for example, to replace mint with minty for whole words only:
sed "s/[[:<:]]mint[[:>:]]/minty/g"
Source: re_format man page
Under "Start" enter "environment" in the search field. That will list the option to change the system variables directly in the start menu.
I used DateTime.Now.TimeOfDay.TotalMilliseconds (for current day), hope it helps you out as well.
In jQuery, you can do alert($("#theid").css("width"))
.
-- if you haven't taken a look at jQuery, I highly recommend it; it makes many simple javascript tasks effortless.
for the record, this post is 5 years old. The web has developed, moved on, etc. There are ways to do this with Plain Old Javascript, which is better.
Perhaps storing a blog post -> comments relation in a non-relational database is not really the best design.
You should probably store comments in a separate collection to blog posts anyway.
[edit]
See comments below for further discussion.
You are trying to call DeckOfCards::shuffle
with a deckOfCards
parameter:
deckOfCards cardDeck; // create DeckOfCards object
cardDeck.shuffle(cardDeck); // shuffle the cards in the deck
But the method takes a vector<Card>&
:
void deckOfCards::shuffle(vector<Card>& deck)
The compiler error messages are quite clear on this. I'll paraphrase the compiler as it talks to you.
Error:
[Error] no matching function for call to 'deckOfCards::shuffle(deckOfCards&)'
Paraphrased:
Hey, pal. You're trying to call a function called
shuffle
which apparently takes a single parameter of type reference-to-deckOfCards
, but there is no such function.
Error:
[Note] candidate is:
In file included from main.cpp
[Note] void deckOfCards::shuffle(std::vector&)
Paraphrased:
I mean, maybe you meant this other function called
shuffle
, but that one takes a reference-tovector<something>
.
Error:
[Note] no known conversion for argument 1 from 'deckOfCards' to 'std::vector&'
Which I'd be happy to call if I knew how to convert from a
deckOfCards
to avector
; but I don't. So I won't.
I am not a big fan of if...else; so I took a simpler approach.
$(document).ready(function(event) {
$('ul.nav.nav-tabs a:first').tab('show'); // Select first tab
$('ul.nav.nav-tabs a[href="'+ window.location.hash+ '"]').tab('show'); // Select tab by name if provided in location hash
$('ul.nav.nav-tabs a[data-toggle="tab"]').on('shown', function (event) { // Update the location hash to current tab
window.location.hash= event.target.hash;
})
});
Doesn't address scrolling to requested hash; but should it?
You can set the horizontal alignment of ticklabels, see the example below. If you imagine a rectangular box around the rotated label, which side of the rectangle do you want to be aligned with the tickpoint?
Given your description, you want: ha='right'
n=5
x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Ticklabel %i' % i for i in range(n)]
fig, axs = plt.subplots(1,3, figsize=(12,3))
ha = ['right', 'center', 'left']
for n, ax in enumerate(axs):
ax.plot(x,y, 'o-')
ax.set_title(ha[n])
ax.set_xticks(x)
ax.set_xticklabels(xlabels, rotation=40, ha=ha[n])
Have a look at git bup which is a Git extension to smartly store large binaries in a Git repository.
You'd want to have it as a submodule, but you won't have to worry about the repository getting hard to handle. One of their sample use cases is storing VM images in Git.
I haven't actually seen better compression rates, but my repositories don't have really large binaries in them.
Your mileage may vary.
Each commit has a unique hash. Other than that there are no revision numbers in git. You'll have to tag commits yourself if you want more user-friendliness.
Correction to above:
<img src="" id="image">
<input id="input" type="file" onchange="handleFiles()">
<script>
function handleFiles()
{
var filesToUpload = document.getElementById('input').files;
var file = filesToUpload[0];
// Create an image
var img = document.createElement("img");
// Create a file reader
var reader = new FileReader();
// Set the image once loaded into file reader
reader.onload = function(e)
{
img.src = e.target.result;
var canvas = document.createElement("canvas");
//var canvas = $("<canvas>", {"id":"testing"})[0];
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0);
var MAX_WIDTH = 400;
var MAX_HEIGHT = 300;
var width = img.width;
var height = img.height;
if (width > height) {
if (width > MAX_WIDTH) {
height *= MAX_WIDTH / width;
width = MAX_WIDTH;
}
} else {
if (height > MAX_HEIGHT) {
width *= MAX_HEIGHT / height;
height = MAX_HEIGHT;
}
}
canvas.width = width;
canvas.height = height;
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0, width, height);
var dataurl = canvas.toDataURL("image/png");
document.getElementById('image').src = dataurl;
}
// Load files into file reader
reader.readAsDataURL(file);
// Post the data
/*
var fd = new FormData();
fd.append("name", "some_filename.jpg");
fd.append("image", dataurl);
fd.append("info", "lah_de_dah");
*/
}</script>
You should try to remove unnecessary images before removing the image:
docker rmi $(docker images --filter "dangling=true" -q --no-trunc)
After that, run:
docker rmi c565603bc87f
There's no need for extra css the .btn-group-justified
class does this.
You have to add this to the parent element and then wrap each btn element in a div with .btn-group like this
<div class="form-group">
<div class="btn-group btn-group-justified">
<div class="btn-group">
<button type="submit" id="like" class="btn btn-lg btn-success ">Like</button>
</div>
<div class="btn-group">
<button type="submit" id="nope" class="btn btn-lg btn-danger ">Nope</button>
</div>
</div>
</div>
IF you have excel 2007, you can use
=NORMSINV(RAND())*SD+MEAN
Because there was a big change in 2010 about excel's function
For a simple array, you have the union approach, but you can also use :
_.uniq([2, 1, 2]);
if the file containing that link tag is in the root dir of the project, then the correct path would be "css/styles.css"
Added some more logic to solution provided by @Andrew Burgess. Here is the full solution:
Created a action filter to get errors for ajax request:
public class ValidateAjaxAttribute : ActionFilterAttribute
{
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
if (!filterContext.HttpContext.Request.IsAjaxRequest())
return;
var modelState = filterContext.Controller.ViewData.ModelState;
if (!modelState.IsValid)
{
var errorModel =
from x in modelState.Keys
where modelState[x].Errors.Count > 0
select new
{
key = x,
errors = modelState[x].Errors.
Select(y => y.ErrorMessage).
ToArray()
};
filterContext.Result = new JsonResult()
{
Data = errorModel
};
filterContext.HttpContext.Response.StatusCode =
(int)HttpStatusCode.BadRequest;
}
}
}
Added the filter to my controller method as:
[HttpPost]
// this line is important
[ValidateAjax]
public ActionResult AddUpdateData(MyModel model)
{
return Json(new { status = (result == 1 ? true : false), message = message }, JsonRequestBehavior.AllowGet);
}
Added a common script for jquery validation:
function onAjaxFormError(data) {
var form = this;
var errorResponse = data.responseJSON;
$.each(errorResponse, function (index, value) {
// Element highlight
var element = $(form).find('#' + value.key);
element = element[0];
highLightError(element, 'input-validation-error');
// Error message
var validationMessageElement = $('span[data-valmsg-for="' + value.key + '"]');
validationMessageElement.removeClass('field-validation-valid');
validationMessageElement.addClass('field-validation-error');
validationMessageElement.text(value.errors[0]);
});
}
$.validator.setDefaults({
ignore: [],
highlight: highLightError,
unhighlight: unhighlightError
});
var highLightError = function(element, errorClass) {
element = $(element);
element.addClass(errorClass);
}
var unhighLightError = function(element, errorClass) {
element = $(element);
element.removeClass(errorClass);
}
Finally added the error javascript method to my Ajax Begin form:
@model My.Model.MyModel
@using (Ajax.BeginForm("AddUpdateData", "Home", new AjaxOptions { HttpMethod = "POST", OnFailure="onAjaxFormError" }))
{
}
You can use TimerTask for Cronjobs.
Main.java
public class Main{
public static void main(String[] args){
Timer t = new Timer();
MyTask mTask = new MyTask();
// This task is scheduled to run every 10 seconds
t.scheduleAtFixedRate(mTask, 0, 10000);
}
}
MyTask.java
class MyTask extends TimerTask{
public MyTask(){
//Some stuffs
}
@Override
public void run() {
System.out.println("Hi see you after 10 seconds");
}
}
Alternative You can also use ScheduledExecutorService.
You can use a background image to accomplish this;
From MDN - Background Size: Contain:
This keyword specifies that the background image should be scaled to be as large as possible while ensuring both its dimensions are less than or equal to the corresponding dimensions of the background positioning area.
CSS:
#im {
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
background-image: url("path/to/img");
background-repeat: no-repeat;
background-size: contain;
}
HTML:
<div id="wrapper">
<div id="im">
</div>
</div>
You can use the following in the web module that produces the war:
<build>
<finalName>bird</finalName>
. . .
</build>
This leads to a file called bird.war to be created when goal "war:war" is used.
locals
in Rails 4.2+In Rails 4.2 I had to remove the locals
part and just use size: 30
instead. Otherwise, it wouldn't pass the local variable correctly.
For example, use this:
<%= render @users, size: 30 %>
You could use the @Rule
annotation with ExpectedException
, like this:
@Rule
public ExpectedException expectedEx = ExpectedException.none();
@Test
public void shouldThrowRuntimeExceptionWhenEmployeeIDisNull() throws Exception {
expectedEx.expect(RuntimeException.class);
expectedEx.expectMessage("Employee ID is null");
// do something that should throw the exception...
System.out.println("=======Starting Exception process=======");
throw new NullPointerException("Employee ID is null");
}
Note that the example in the ExpectedException
docs is (currently) wrong - there's no public constructor, so you have to use ExpectedException.none()
.
Your file will probably be cached - but it depends...
Different browsers have slightly different behaviors - most noticeably when dealing with ambiguous/limited caching headers emanating from the server. If you send a clear signal, the browsers obey, virtually all of the time.
The greatest variance by far, is in the default caching configuration of different web servers and application servers.
Some (e.g. Apache) are likely to serve known static file types with HTTP headers encouraging the browser to cache them, while other servers may send no-cache
commands with every response - regardless of filetype.
...
So, first off, read some of the excellent HTTP caching tutorials out there. HTTP Caching & Cache-Busting for Content Publishers was a real eye opener for me :-)
Next install and fiddle around with Firebug and the Live HTTP Headers add-on , to find out which headers your server is actually sending.
Then read your web server docs to find out how to tweak them to perfection (or talk your sysadmin into doing it for you).
...
As to what happens when the browser is restarted, it depends on the browser and the user configuration.
As a rule of thumb, expect the browser to be more likely to check in with the server after each restart, to see if anything has changed (see If-Last-Modified and If-None-Match).
If you configure your server correctly, it should be able to return a super-short 304 Not Modified (costing very little bandwidth) and after that the browser will use the cache as normal.
I see this isn't answered yet, this is an exact quote from here:
WSHttpBinding will try and perform an internal negotiate at the SSP layer. In order for this to be successful, you will need to allow anonymous in IIS for the VDir. WCF will then by default perfrom an SPNEGO for window credentials. Allowing anonymous at IIS layer is not allowing anyone in, it is deferring to the WCF stack.

That looks like it might belong in the select statement:
SELECT id, col1, col2, col3, (CASE WHEN table3.col3 IS NULL THEN table2.col3 AS col4 ELSE table3.col3 as col4 END)
FROM table1
LEFT OUTER JOIN table2
ON table1.id = table2.id
LEFT OUTER JOIN table3
ON table1.id = table3.id
How about

I got this error when I tried to install pymssql even though Visual C++ 2015 (14.0) is installed in my system.
I resolved this error by downloading the .whl file of pymssql from here.
Once downloaded, it can be installed by the following command :
pip install python_package.whl
Hope this helps
If you get an error 1044 (42000) when you try to run SQL commands in MySQL (which installed along XAMPP server) cmd prompt, then here's the solution:
Close your MySQL command prompt.
Open your cmd prompt (from Start menu -> run -> cmd) which will show: C:\Users\User>_
Go to MySQL.exe by Typing the following commands:
C:\Users\User>cd\
C:\>cd xampp
C:\xampp>cd mysql
C:\xxampp\mysql>cd bin
C:\xampp\mysql\bin>mysql -u root
Now try creating a new database by typing:
mysql> create database employee;
if it shows:
Query OK, 1 row affected (0.00 sec)
mysql>
Then congrats ! You are good to go...
For the height of a div to be responsive, it must be inside a parent element with a defined height to derive it's relative height from.
If you set the height of the container holding the image and text box on the right, you can subsequently set the heights of its two children to be something like 75% and 25%.
However, this will get a bit tricky when the site layout gets narrower and things will get wonky. Try setting the padding on .contentBg to something like 5.5%.
My suggestion is to use Media Queries to tweak the padding at different screen sizes, then bump everything into a single column when appropriate.
$A = array('a' => 1, 'b' => 2, 'c' => 3);
$B = array('c' => 4, 'd'=> 5);
$C = array_merge_recursive($A, $B);
$aWhere = array();
foreach ($C as $k=>$v) {
if (is_array($v)) {
$aWhere[] = $k . ' in ('.implode(', ',$v).')';
}
else {
$aWhere[] = $k . ' = ' . $v;
}
}
$where = implode(' AND ', $aWhere);
echo $where;
You can use the base64
module to encode strings to stop shoulder surfing, but it's not going to stop someone finding your code if they have access to your files.
You can then use the compile()
function and the eval()
function to execute your code once you've decoded it.
>>> import base64
>>> mycode = "print 'Hello World!'"
>>> secret = base64.b64encode(mycode)
>>> secret
'cHJpbnQgJ2hlbGxvIFdvcmxkICEn'
>>> mydecode = base64.b64decode(secret)
>>> eval(compile(mydecode,'<string>','exec'))
Hello World!
So if you have 30 lines of code you'll probably want to encrypt it doing something like this:
>>> f = open('myscript.py')
>>> encoded = base64.b64encode(f.read())
You'd then need to write a second script that does the compile()
and eval()
which would probably include the encoded script as a string literal encased in triple quotes. So it would look something like this:
import base64
myscript = """IyBUaGlzIGlzIGEgc2FtcGxlIFB5d
GhvbiBzY3JpcHQKcHJpbnQgIkhlbG
xvIiwKcHJpbnQgIldvcmxkISIK"""
eval(compile(base64.b64decode(myscript),'<string>','exec'))
Using LINQ, ofcourse. The below code would give you dictionary of item as string, and the count of each item in your sourc list.
var item2ItemCount = list.GroupBy(item => item).ToDictionary(x=>x.Key,x=>x.Count());
Although other answers are correct they are setting the global config value whereas there is a default git location for the global git ignore file:
*nix:
~/.config/git/ignore
Windows:
%USERPROFILE%\git\ignore
You may need to create git
directory and ignore
file but then you can put your global ignores into that file and that's it!
Which file to place a pattern in depends on how the pattern is meant to be used.
…
- Patterns which a user wants Git to ignore in all situations (e.g., backup or temporary files generated by the user’s editor of choice) generally go into a file specified by
core.excludesFile
in the user’s~/.gitconfig
. Its default value is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore is used instead.
Updating @Crashalot's answer for Swift 3.x:
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
if let touch = touches.first {
let currentPoint = touch.location(in: self)
// do something with your currentPoint
}
}
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
if let touch = touches.first {
let currentPoint = touch.location(in: self)
// do something with your currentPoint
}
}
override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
if let touch = touches.first {
let currentPoint = touch.location(in: self)
// do something with your currentPoint
}
}
A simpler version, for easy eyes!
@(true?"yes":"no")
other.component.ts
So final correct solution is :
import { Component, OnInit } from '@angular/core';
import { Location } from '@angular/common';
import { Router } from '@angular/router';
/* 'router' it must be in small case */
@Component({
selector: 'app-other',
templateUrl: './other.component.html',
styleUrls: ['./other.component.css']
})
export class OtherComponent implements OnInit {
public href: string = "";
url: string = "asdf";
constructor(private router : Router) {} // make variable private so that it would be accessible through out the component
ngOnInit() {
this.href = this.router.url;
console.log(this.router.url);
}
}
auto
was a keyword that C++ "inherited" from C that had been there nearly forever, but virtually never used because there were only two possible conditions: either it wasn't allowed, or else it was assumed by default.
The use of auto
to mean a deduced type was new with C++11.
At the same time, auto x = initializer
deduces the type of x
from the type of initializer
the same way as template type deduction works for function templates. Consider a function template like this:
template<class T>
int whatever(T t) {
// point A
};
At point A, a type has been assigned to T
based on the value passed for the parameter to whatever
. When you do auto x = initializer;
, the same type deduction is used to determine the type for x
from the type of initializer
that's used to initialize it.
This means that most of the type deduction mechanics a compiler needs to implement auto
were already present and used for templates on any compiler that even sort of attempted to implement C++98/03. As such, adding support for auto
was apparently fairly easy for essentially all the compiler teams--it was added quite quickly, and there seem to have been few bugs related to it either.
When this answer was originally written (in 2011, before the ink was dry on the C++ 11 standard) auto
was already quite portable. Nowadays, it's thoroughly portable among all the mainstream compilers. The only obvious reasons to avoid it would be if you need to write code that's compatible with a C compiler, or you have a specific need to target some niche compiler that you know doesn't support it (e.g., a few people still write code for MS-DOS using compilers from Borland, Watcom, etc., that haven't seen significant upgrades in decades). If you're using a reasonably current version of any of the mainstream compilers, there's no reason to avoid it at all though.
Looks like you created a separate question. I was answering your other question How to change flat file source using foreach loop container in an SSIS package? with the same answer. Anyway, here it is again.
Create two string data type variables namely DirPath
and FilePath
. Set the value C:\backup\ to the variable DirPath
. Do not set any value to the variable FilePath
.
Select the variable FilePath
and select F4 to view the properties. Set the EvaluateAsExpression
property to True and set the Expression property as @[User::DirPath] + "Source" + (DT_STR, 4, 1252) DATEPART("yy" , GETDATE()) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2)
s = "I am having a very nice 23!@$ day. "
sum([i.strip(string.punctuation).isalpha() for i in s.split()])
The statement above will go through each chunk of text and remove punctuations before verifying if the chunk is really string of alphabets.
It's very important to point out that view.layoutIfNeeded()
applies to the view subviews only.
Therefore to animate the view constraint, it is important to call it on the view-to-animate superview as follows:
topConstraint.constant = heightShift
UIView.animate(withDuration: 0.3) {
// request layout on the *superview*
self.view.superview?.layoutIfNeeded()
}
An example for a simple layout as follows:
class MyClass {
/// Container view
let container = UIView()
/// View attached to container
let view = UIView()
/// Top constraint to animate
var topConstraint = NSLayoutConstraint()
/// Create the UI hierarchy and constraints
func createUI() {
container.addSubview(view)
// Create the top constraint
topConstraint = view.topAnchor.constraint(equalTo: container.topAnchor, constant: 0)
view.translatesAutoresizingMaskIntoConstraints = false
// Activate constaint(s)
NSLayoutConstraint.activate([
topConstraint,
])
}
/// Update view constraint with animation
func updateConstraint(heightShift: CGFloat) {
topConstraint.constant = heightShift
UIView.animate(withDuration: 0.3) {
// request layout on the *superview*
self.view.superview?.layoutIfNeeded()
}
}
}
Based on this forum post: https://groups.google.com/forum/#!topic/ggplot2/mK9DR3dKIBU
Sounds like the easiest thing to do is to add a line break (\n) before your x axis, and after your y axis labels. Seems a lot easier (although dumber) than the solutions posted above.
ggplot(mpg, aes(cty, hwy)) +
geom_point() +
xlab("\nYour_x_Label") + ylab("Your_y_Label\n")
Hope that helps!
Here is a pretty good way to do it
http://support.microsoft.com/kb/555972
System.Collections.ArrayList arr = new System.Collections.ArrayList();
arr.Add("1");
arr.Add("2");
arr.Add("3");
/*This throws an exception
foreach (string s in arr)
{
arr.Remove(s);
}
*/
//where as this works correctly
Console.WriteLine(arr.Count);
foreach (string s in new System.Collections.ArrayList(arr))
{
arr.Remove(s);
}
Console.WriteLine(arr.Count);
Console.ReadKey();
It might be most sensible to use multiprocessing.Pool
which produces a pool of worker processes based on the max number of cores available on your system, and then basically feeds tasks in as the cores become available.
The example from the standard docs (http://docs.python.org/2/library/multiprocessing.html#using-a-pool-of-workers) shows that you can also manually set the number of cores:
from multiprocessing import Pool
def f(x):
return x*x
if __name__ == '__main__':
pool = Pool(processes=4) # start 4 worker processes
result = pool.apply_async(f, [10]) # evaluate "f(10)" asynchronously
print result.get(timeout=1) # prints "100" unless your computer is *very* slow
print pool.map(f, range(10)) # prints "[0, 1, 4,..., 81]"
And it's also handy to know that there is the multiprocessing.cpu_count()
method to count the number of cores on a given system, if needed in your code.
Edit: Here's some draft code that seems to work for your specific case:
import multiprocessing
def f(name):
print 'hello', name
if __name__ == '__main__':
pool = multiprocessing.Pool() #use all available cores, otherwise specify the number you want as an argument
for i in xrange(0, 512):
pool.apply_async(f, args=(i,))
pool.close()
pool.join()
You can use
substr(string $string, int $start, int[optional] $length=null);
See substr in the PHP documentation. It returns part of a string.
Note that you can only read a stream once, so in some cases, you may need to clone the response in order to repeatedly read it:
fetch('example.json')
.then(res=>res.clone().json())
.then( json => console.log(json))
fetch('url_that_returns_text')
.then(res=>res.clone().text())
.then( text => console.log(text))
The good news is a transaction in SQL Server can span multiple batches (each exec
is treated as a separate batch.)
You can wrap your EXEC
statements in a BEGIN TRANSACTION
and COMMIT
but you'll need to go a step further and rollback if any errors occur.
Ideally you'd want something like this:
BEGIN TRY
BEGIN TRANSACTION
exec( @sqlHeader)
exec(@sqlTotals)
exec(@sqlLine)
COMMIT
END TRY
BEGIN CATCH
IF @@TRANCOUNT > 0
ROLLBACK
END CATCH
The BEGIN TRANSACTION
and COMMIT
I believe you are already familiar with. The BEGIN TRY
and BEGIN CATCH
blocks are basically there to catch and handle any errors that occur. If any of your EXEC
statements raise an error, the code execution will jump to the CATCH
block.
Your existing SQL building code should be outside the transaction (above) as you always want to keep your transactions as short as possible.
<?php
$fh = fopen('filename.txt','r');
while ($line = fgets($fh)) {
// <... Do your work with the line ...>
// echo($line);
}
fclose($fh);
?>
This will give you a line by line read.. read the notes at php.net/fgets regarding the end of line issues with Macs.
select distinct(city) from STATION
where lower(substr(city, -1)) in ('a','e','i','o','u')
and lower(substr(city, 1,1)) in ('a','e','i','o','u');
Try this:
for (var i in tracks[racer_id].data.points) {
values = tracks[racer_id].data.points[i];
point = new google.maps.LatLng(values.lat, values.lng);
if (values.qst) {
var marker = new google.maps.Marker({map: map, position: point, clickable: true});
tracks[racer_id].markers[i] = marker;
var info = new google.maps.InfoWindow({
content: '<b>Speed:</b> ' + values.inst + ' knots'
});
tracks[racer_id].info[i] = info;
google.maps.event.addListener(tracks[racer_id].markers[i], 'click', function() {
tracks[racer_id].info[i].open(map, tracks[racer_id].markers[i]);
});
}
track_coordinates.push(point);
bd.extend(point);
}
I recommend you to use JSON.NET
. it is an open source library to serialize and deserialize your c# objects into json and Json objects into .net objects ...
Serialization Example:
Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };
string json = JsonConvert.SerializeObject(product);
//{
// "Name": "Apple",
// "Expiry": new Date(1230422400000),
// "Price": 3.99,
// "Sizes": [
// "Small",
// "Medium",
// "Large"
// ]
//}
Product deserializedProduct = JsonConvert.DeserializeObject<Product>(json);
Performance Comparison To Other JSON serializiation Techniques
Add Permission Internet permission in manifest.

This code it working
public class WebActivity extends Activity {
WebView wv;
String url="http://www.teluguoneradio.com/rssHostDescr.php?hostId=147";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web);

WebSettings webSettings = wv.getSettings();
wv.getSettings().setLoadWithOverviewMode(true);
wv.getSettings().setUseWideViewPort(true);
wv.getSettings().setBuiltInZoomControls(true);
wv.getSettings().setPluginState(PluginState.ON);
wv.setWebViewClient(new myWebClient());
wv.loadUrl(url);
}
public class myWebClient extends WebViewClient {
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
These queries will also work:
Workaround 1)
SELECT ename, sal
FROM Emp e1 WHERE n-1 = (SELECT COUNT(DISTINCT sal)
FROM Emp e2 WHERE e2.sal > e1.sal)
Workaround 2) using row_num function.
SELECT *
FROM (
SELECT e.*, ROW_NUMBER() OVER (ORDER BY sal DESC) rn FROM Emp e
) WHERE rn = n;
Workaround 3 ) using rownum pseudocolumn
Select MAX(SAL)
from (
Select *
from (
Select *
from EMP
order by SAL Desc
) where rownum <= n
)
This works for me and is quite simple:
Import these:
import java.awt.datatransfer.StringSelection;
import java.awt.Toolkit;
import java.awt.datatransfer.Clipboard;
And then put this snippet of code wherever you'd like to alter the clipboard:
String myString = "This text will be copied into clipboard";
StringSelection stringSelection = new StringSelection(myString);
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
clipboard.setContents(stringSelection, null);
First you should use print_r($_FILES)
to debug, and see what it contains. :
your uploads.php
would look like:
//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);
//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];
//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
//Tells you if its all ok
echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
// Connects to your Database
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;
//Writes the information to the database
mysql_query("INSERT INTO picture (Filename,Description)
VALUES ('$Filename', '$Description')") ;
} else {
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>
EDIT: Since this is old post, currently it is strongly recommended to use either mysqli or pdo instead mysql_ functions in php
If you use "firebase-functions" to host your sever-side-rendered application, you should be aware of this one:
error: Error: ENOENT: no such file or directory, open 'C:\Codes\url_shortener\functions\.env'
Means you have to store the .env file in the functions folder as well.
Found this one by:
console.log(require('dotenv').config())
Why not to try simple (but powerful) html()
method:
iElement.html('<svg width="600" height="100" class="svg"></svg>');
Or append
as an alternative:
iElement.append('<svg width="600" height="100" class="svg"></svg>');
And , of course , more cleaner way:
var svg = angular.element('<svg width="600" height="100" class="svg"></svg>');
iElement.append(svg);
If you are using implicit Authentication must have the problem of not being able to find the user_id
I found a way for example:
Access Token = 1506417331.18b98f6.8a00c0d293624ded801d5c723a25d3ec
the User id is 1506417331
would you do a split single seperated by . obtenies to acces token and the first element
You need to use __repr__
. This is a standard function like __init__
.
For example:
class Foobar():
"""This will create Foobar type object."""
def __init__(self):
print "Foobar object is created."
def __repr__(self):
return "Type what do you want to see here."
a = Foobar()
print a
Yes. In your login
module, just export a single function that takes the db
as its argument. For example:
module.exports = function(db) {
...
};
There are two ways of storing a color with alpha. The first is exactly as you see it, with each component as-is. The second is to use pre-multiplied alpha, where the color values are multiplied by the alpha after converting it to the range 0.0-1.0; this is done to make compositing easier. Ordinarily you shouldn't notice or care which way is implemented by any particular engine, but there are corner cases where you might, for example if you tried to increase the opacity of the color. If you use rgba(0, 0, 0, 0)
you are less likely to to see a difference between the two approaches.
At HauteLook, we changed many of our tables to use natural keys. We did experience a real-world increase in performance. As you mention, many of our queries now use less joins which makes the queries more performant. We will even use a composite primary key if it makes sense. That being said, some tables are just easier to work with if they have a surrogate key.
Also, if you are letting people write interfaces to your database, a surrogate key can be helpful. The 3rd party can rely on the fact that the surrogate key will change only in very rare circumstances.
For a simple way, use system()
:
#include <stdlib.h>
...
int status = system("./foo 1 2 3");
system()
will wait for foo to complete execution, then return a status variable which you can use to check e.g. exitcode (the command's exitcode gets multiplied by 256, so divide system()'s return value by that to get the actual exitcode: int exitcode = status / 256
).
The manpage for wait()
(in section 2, man 2 wait
on your Linux system) lists the various macros you can use to examine the status, the most interesting ones would be WIFEXITED
and WEXITSTATUS
.
Alternatively, if you need to read foo's standard output, use popen(3)
, which returns a file pointer (FILE *
); interacting with the command's standard input/output is then the same as reading from or writing to a file.
You should be aware that values of fields could contain commas and quotation characters, so some of the suggested answers would not work, as the CSV output file would not be correct. To replace quotation characters in a field, and replace it with the double quotation character, you can use the REPLACE function that oracle provides, to change a single quote to double quote.
set echo off
set heading off
set feedback off
set linesize 1024 -- or some other value, big enough
set pagesize 50000
set verify off
set trimspool on
spool output.csv
select trim(
'"' || replace(col1, '"', '""') ||
'","' || replace(col2, '"', '""') ||
'","' || replace(coln, '"', '""') || '"' ) -- etc. for all the columns
from yourtable
/
spool off
Or, if you want the single quote character for the fields:
set echo off
set heading off
set feedback off
set linesize 1024 -- or some other value, big enough
set pagesize 50000
set verify off
set trimspool on
spool output.csv
select trim(
'"' || replace(col1, '''', '''''') ||
'","' || replace(col2, '''', '''''') ||
'","' || replace(coln, '''', '''''') || '"' ) -- etc. for all the columns
from yourtable
/
spool off
Did you check the string concatenation function? Something like:
update table_c set column_a = column_b || column_c
should work. More here

For me, I was pushing the changes to a private repo to which I didn't had the write access. Make sure you have the valid access rights while performing push or pull operations.
You can directly verify via
Use a script like the following to execute the rest or part of the script under another user:
#!/bin/sh
id
exec sudo -u transmission /bin/sh - << eof
id
eof
You can do like
$timeout(function() {
angular.element('#btn2').triggerHandler('click');
});
Improved @Andrew's answer above :
Array.from({ length : 1 }, () => Math.random().toString(36)[2]).join('');
Base 36 conversion of the random number is inconsistent, so selecting a single indice fixes that. You can change the length for a string with the exact length desired.
I think that once you've imported it, the behaviour is the same (in the place your variable will be used outside source file).
The only difference would be if you try to reassign it before the end of this very file.
No, you don't have to bother grep.
find $dir -size 0 ! -name "*.xml"
In my case, I was attempting to pass an object into a template via an express route (akin to OPs setup). Then I wanted to pass that object into a function I was calling via a script tag in a pug template. Though lagginreflex's answer got me close, I ended up with the following:
script.
var data = JSON.parse('!{JSON.stringify(routeObj)}');
funcName(data)
This ensured the object was passed in as expected, rather than needing to deserialise in the function. Also, the other answers seemed to work fine with primitives, but when arrays etc. were passed along with the object they were parsed as string values.
One way to fix it is by modifying the assembly redirect in the web.config file.
Modify the following:
<dependentAssembly>
<assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
</dependentAssembly>
to
<dependentAssembly>
<assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.2.3.0" newVersion="4.0.0.0" />
</dependentAssembly>
So the oldVersion attribute should change from "...-4.0.0.0" to "...-5.2.3.0".
If anyone is trying to generate a diff file from two branches :
git diff master..otherbranch > myDiffFile.diff
In Rails 4.1.0, I have faced problem with saving latitude and longitude to MySql database. It can't save large fraction number with float data type. And I change the data type to decimal and working for me.
def change change_column :cities, :latitude, :decimal, :precision => 15, :scale => 13 change_column :cities, :longitude, :decimal, :precision => 15, :scale => 13 end
@article = user.articles.build(:title => "MainTitle")
@article.save
You should change the query to:
SELECT time_col, COUNT(time_col) As Count
FROM time_table
WHERE activity_col = 3
GROUP BY time_col
This vl works correctly.
A dummy answer :-
I think explanation is given in above answer, so i am just gonna tell you where to use STRONG
and where to use WEAK
:
Use of Weak
:-
1. Delegates
2. Outlets
3. Subviews
4. Controls, etc.
Use of Strong
:-
Remaining everywhere which is not included in WEAK
.
If you need or want a simple HTTP server with the following:
I built one on top of the excellent SimpleHTTPAuthServer already on PyPI. This adds handling of POST requests: https://github.com/arielampol/SimpleHTTPAuthServerWithPOST
Otherwise, all the other options publicly available are already so good and robust.
I wasted too much time on this, I find that the AVAST is the issue!!!
If you have AVAST installed in you system, you have to:
Go to
settings
tab -->troubleshooting
, then you should UNCHECK the "enable hardware-assisted virtualization
"
Restart your PC, the install the intelhaxm-android.exe if it is not installed. You can find it:
C:\Users\{YOURUSERNAME}\AppData\Local\Android\sdk\extras\intel\Hardware_Accelerated_Execution_Manager
Beside of read.csv(url("..."))
you also can use read.table("http://...")
.
Example:
> sample <- read.table("http://www.ats.ucla.edu/stat/examples/ara/angell.txt")
> sample
V1 V2 V3 V4 V5
1 Rochester 19.0 20.6 15.0 E
2 Syracuse 17.0 15.6 20.2 E
...
43 Atlanta 4.2 70.6 32.6 S

Use chooseOkOnNextConfirmation() to dismiss the alert and getAlert() to verify that it has been shown (and optionally grab its text for verification).
selenium.chooseOkOnNextConfirmation(); // prepares Selenium to handle next alert
selenium.click(locator);
String alertText = selenium.getAlert(); // verifies that alert was shown
assertEquals("This is a popup window", alertText);
...
A simple way to do so is to add the below code (for Seaborn):
for p in splot.patches:
splot.annotate(format(p.get_height(), '.1f'),
(p.get_x() + p.get_width() / 2., p.get_height()),
ha = 'center', va = 'center',
xytext = (0, 9),
textcoords = 'offset points')
Example :
splot = sns.barplot(df['X'], df['Y'])
# Annotate the bars in plot
for p in splot.patches:
splot.annotate(format(p.get_height(), '.1f'),
(p.get_x() + p.get_width() / 2., p.get_height()),
ha = 'center', va = 'center',
xytext = (0, 9),
textcoords = 'offset points')
plt.show()
It's not possible to do multi-shot playing with a single <audio>
element. You need to use multiple elements for this.
jQuery's documentation states:
[jQuery.val] checks, or selects, all the radio buttons, checkboxes, and select options that match the set of values.
This behavior is in jQuery
versions 1.2
and above.
You most likely want this:
$("._statusDDL").val('2');
In my case, I forgot to tell the type controller that the response is a JSON object. response.setContentType("application/json");
Usually SelectedItems
returns either a collection, an array or an IQueryable
.
Either way you can access items via the index as with an array:
String text = listView1.SelectedItems[0].Text;
By the way, you can save an item you want to look at into a variable, and check its structure in the locals after setting a breakpoint.
Make sure no other apache servers are running as it generates an error when you try to access it on the browser even with a different port. Go to Finder and below Device you will usually see the lampp icon. You can also open the htdocs from any of the ide or code editor by opening files or project once you locate the lampp icon. Make sure you mount the stack.
Browsers can often tell the image type by sniffing out the meta information of the image. Also, there should be a space in that header:
header('Content-type: image/png');
@xpmatteo has the answer to disabling portions of code, but in addition to this, the default eclipse settings should be set to only format edited lines of code instead of the whole file.
Preferences->Java->Editor->Save Actions->Format Source Code->Format Edited Lines
This would have prevented it from happening in the first place since your coworkers are reformatting code they didn't actually change. This is a good practice to prevent mishaps that render diff on your source control useless (when an entire file is reformatted because of minor format setting differences).
It would also prevent the reformatting if the on/off tags option was turned off.
Yep, and just don't forget to use variables like %%1
when using if
and for
and the gang.
If you forget the double %
, then you will be substituting in (possibly null) command line arguments and you will receive some pretty confusing error messages.

Android Native Icons (Recommended) You can change color of these icons programmatically. https://design.google.com/icons/
This cannot be answered that easily. It depends on the font used and the points per inch (ppi). This should give an overview of the problem.
You can also use apply
with .get
i.e.
w['female'] = w['female'].apply({'male':0, 'female':1}.get)
:
w = pd.DataFrame({'female':['female','male','female']})
print(w)
Dataframe w
:
female
0 female
1 male
2 female
Using apply
to replace values from the dictionary:
w['female'] = w['female'].apply({'male':0, 'female':1}.get)
print(w)
Result:
female
0 1
1 0
2 1
Note: apply
with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.
You could probably use a set object instead. Just add
numbers to the set. They inherently do not replicate.
Following worked for me in C++11:
template <typename Enum>
constexpr typename std::enable_if<std::is_enum<Enum>::value,
typename std::underlying_type<Enum>::type>::type
to_integral(Enum const& value) {
return static_cast<typename std::underlying_type<Enum>::type>(value);
}
You could pipe your grep output into Perl like this:
grep "th" * | perl -n -e'while(/(\w*th\w*)/g) {print "$1\n"}'
The existing answers already cover the "how", but I just wanted to elaborate on the "what" and "why" for others who might be wondering.
What a compiler (gcc) does: The term "compile" is a bit of an overloaded term because it is used at a high-level to mean "convert source code to a program", but more technically means to "convert source code to object code". A compiler like gcc actually performs two related, but arguably distinct functions to turn your source code into a program: compiling (as in the latter definition of turning source to object code) and linking (the process of combining the necessary object code files together into one complete executable).
The original error that you saw is technically a "linking error", and is thrown by "ld", the linker. Unlike (strict) compile-time errors, there is no reference to source code lines, as the linker is already in object space.
By default, when gcc is given source code as input, it attempts to compile each and then link them all together. As noted in the other responses, it's possible to use flags to instruct gcc to just compile first, then use the object files later to link in a separate step. This two-step process may seem unnecessary (and probably is for very small programs) but it is very important when managing a very large program, where compiling the entire project each time you make a small change would waste a considerable amount of time.
obj= Model.objects.filter(testfield=12).order_by('-id')[0]
Use simple CSS3 (not supported in IE<9)
img
{
box-shadow: 0px 0px 5px #fff;
}
This will put a white glow around every image in your document, use more specific selectors to choose which images you'd like the glow around. You can change the color of course :)
If you're worried about the users that don't have the latest versions of their browsers, use this:
img
{
-moz-box-shadow: 0 0 5px #fff;
-webkit-box-shadow: 0 0 5px #fff;
box-shadow: 0px 0px 5px #fff;
}
For IE you can use a glow filter (not sure which browsers support it)
img
{
filter:progid:DXImageTransform.Microsoft.Glow(Color=white,Strength=5);
}
Play with the settings to see what suits you :)

You have misspelt the second pixels
as pixel
. The following works:
pixels = [1,2,3]
pixels[0] = 5
It appears that due to the typo you were trying to accidentally modify some tuple called pixel
, and in Python tuples are immutable. Hence the confusing error message.
npm outdated
will identify packages that should be updated, and npm update <package name>
can be used to update each package. But prior to [email protected], npm update <package name>
will not update the versions in your package.json which is an issue.
The best workflow is to:
npm update
to install the latest versions of each packageCheck out npm-check-updates
to help with this workflow.
npm-check-updates
to list what packages are out of date (basically the same thing as running npm outdated
)npm-check-updates -u
to update all the versions in your package.json (this is the magic sauce)npm update
as usual to install the new versions of your packages based on the updated package.jsonI use the following code:
<Button onClick={this.onSubmit} id={item.key} value={shop.ethereum}>
Approve
</Button>
Then inside the method:
onSubmit = async event => {
event.preventDefault();
event.persist();
console.log("Param passed => Eth addrs: ", event.target.value)
console.log("Param passed => id: ", event.target.id)
...
}
As a result:
Param passed in event => Eth addrs: 0x4D86c35fdC080Ce449E89C6BC058E6cc4a4D49A6
Param passed in event => id: Mlz4OTBSwcgPLBzVZ7BQbwVjGip1
Another way of doing it would be:
stuff = Object.assign(stuff, {$(this).attr('value'):$(this).attr('checked')});
Read more here: Object.assign()
The fragment identifier (also known as: Fragment IDs, Anchor Identifiers, Named Anchors) introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.
<a href="http://www.someuri.com/page#fragment">Link to fragment identifier</a>
Syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment the fragment follows the query.
<a href="http://www.someuri.com/page?query=1#fragment">Link to fragment with a query</a>
When a Web browser requests a resource from a Web server, the agent sends the URI to the server, but does not send the fragment. Instead, the agent waits for the server to send the resource, and then the agent (Web browser) processes the resource according to the document type and fragment value.
Named Anchors <a name="fragment">
are deprecated in XHTML 1.0, the ID attribute is the suggested replacement. <div id="fragment"></div>
Each version has some improvements in certain technologies. For users the biggest difference is whether or not to execute certain plugins, because some were made only for a particular version of Eclipse.
I use an extension method for this. My extension method first checks to see if the enumeration is null and if so creates an empty list. This allows you to do a foreach on it without explicitly having to check for null.
Here is a very contrived example:
IEnumerable<string> stringEnumerable = null;
StringBuilder csv = new StringBuilder();
stringEnumerable.ToNonNullList().ForEach(str=> csv.Append(str).Append(","));
Here is the extension method:
public static List<T> ToNonNullList<T>(this IEnumerable<T> obj)
{
return obj == null ? new List<T>() : obj.ToList();
}
Replace the * with a /
So instead of
COPY * <destination>
use
COPY / <destination>
Admittedly, my solution wouldn't work for negative integers, but it will extract all positive integers from input text containing integers. It makes use of numeric_only
locale:
int main() {
int num;
std::cin.imbue(std::locale(std::locale(), new numeric_only()));
while ( std::cin >> num)
std::cout << num << std::endl;
return 0;
}
Input text:
the format (-5) or (25) etc... some text.. and then.. 7987...78hjh.hhjg9878
Output integers:
5
25
7987
78
9878
The class numeric_only
is defined as:
struct numeric_only: std::ctype<char>
{
numeric_only(): std::ctype<char>(get_table()) {}
static std::ctype_base::mask const* get_table()
{
static std::vector<std::ctype_base::mask>
rc(std::ctype<char>::table_size,std::ctype_base::space);
std::fill(&rc['0'], &rc[':'], std::ctype_base::digit);
return &rc[0];
}
};

To get around the html
vs body
issue, I fixed this by not animating the css directly but rather calling window.scrollTo();
on each step:
$({myScrollTop:window.pageYOffset}).animate({myScrollTop:300}, {
duration: 600,
easing: 'swing',
step: function(val) {
window.scrollTo(0, val);
}
});
This works nicely without any refresh gotchas as it's using cross-browser JavaScript.
Have a look at http://james.padolsey.com/javascript/fun-with-jquerys-animate/ for more information on what you can do with jQuery's animate function.
.toString()
is available, or just add ""
to the end of the int
var x = 3,
toString = x.toString(),
toConcat = x + "";
Angular is simply JavaScript at the core.
string.join
connects elements inside list of strings, not ints.
Use this generator expression instead :
values = ','.join(str(v) for v in value_list)
Try:
^[1-9][0-9]?$|^100$
EDIT: IF you want to match 00001, 00000099 try
^0*(?:[1-9][0-9]?|100)$
Hmya, the enduring mystique of DoEvents(). There's been an enormous amount of backlash against it, but nobody ever really explains why it is "bad". The same kind of wisdom as "don't mutate a struct". Erm, why does the runtime and the language supports mutating a struct if that's so bad? Same reason: you shoot yourself in the foot if you don't do it right. Easily. And doing it right requires knowing exactly what it does, which in the case of DoEvents() is definitely not easy to grok.
Right off the bat: almost any Windows Forms program actually contains a call to DoEvents(). It is cleverly disguised, however with a different name: ShowDialog(). It is DoEvents() that allows a dialog to be modal without it freezing the rest of the windows in the application.
Most programmers want to use DoEvents to stop their user interface from freezing when they write their own modal loop. It certainly does that; it dispatches Windows messages and gets any paint requests delivered. The problem however is that it isn't selective. It not only dispatches paint messages, it delivers everything else as well.
And there's a set of notifications that cause trouble. They come from about 3 feet in front of the monitor. The user could for example close the main window while the loop that calls DoEvents() is running. That works, user interface is gone. But your code didn't stop, it is still executing the loop. That's bad. Very, very bad.
There's more: The user could click the same menu item or button that causes the same loop to get started. Now you have two nested loops executing DoEvents(), the previous loop is suspended and the new loop is starting from scratch. That could work, but boy the odds are slim. Especially when the nested loop ends and the suspended one resumes, trying to finish a job that was already completed. If that doesn't bomb with an exception then surely the data is scrambled all to hell.
Back to ShowDialog(). It executes DoEvents(), but do note that it does something else. It disables all the windows in the application, other than the dialog. Now that 3-feet problem is solved, the user cannot do anything to mess up the logic. Both the close-the-window and start-the-job-again failure modes are solved. Or to put it another way, there is no way for the user to make your program run code in a different order. It will execute predictably, just like it did when you tested your code. It makes dialogs extremely annoying; who doesn't hate having a dialog active and not being able to copy and paste something from another window? But that's the price.
Which is what it takes to use DoEvents safely in your code. Setting the Enabled property of all your forms to false is a quick and efficient way to avoid problems. Of course, no programmer ever actually likes doing this. And doesn't. Which is why you shouldn't use DoEvents(). You should use threads. Even though they hand you a complete arsenal of ways to shoot your foot in colorful and inscrutable ways. But with the advantage that you only shoot your own foot; it won't (typically) let the user shoot hers.
The next versions of C# and VB.NET will provide a different gun with the new await and async keywords. Inspired in small part by the trouble caused by DoEvents and threads but in large part by WinRT's API design that requires you to keep your UI updated while an asynchronous operation is taking place. Like reading from a file.
One nice way (without adding a fake .js extension which is for code not for data and configs) is to use json-loader
module. If you have used create-react-app
to scaffold your project, the module is already included, you just need to import your json:
import Profile from './components/profile';
This answer explains more.
That's right, if you're on a mac(unix) you won't see .git in finder(the file browser). You can follow the directions above to delete and there are git commands that allow you to delete files as well(they are sometimes difficult to work with and learn, for example: on making a 'git rm -r ' command you might be prompted with a .git/ not found. Here is the git command specs:
usage: git rm [options] [--] ...
-n, --dry-run dry run
-q, --quiet do not list removed files
--cached only remove from the index
-f, --force override the up-to-date check
-r allow recursive removal
--ignore-unmatch exit with a zero status even if nothing matched
When I had to do this, deleting the objects and refs didn't matter. After I deleted the other files in the .git, I initialized a git repo with 'git init' and it created an empty repo.
Enyo's tutorial is excellent.
I found that the sample script in the tutorial worked well for a button embedded in the dropzone (i.e., the form element). If you wish to have the button outside the form element, I was able to accomplish it using a click event:
First, the HTML:
<form id="my-awesome-dropzone" action="/upload" class="dropzone">
<div class="dropzone-previews"></div>
<div class="fallback"> <!-- this is the fallback if JS isn't working -->
<input name="file" type="file" multiple />
</div>
</form>
<button type="submit" id="submit-all" class="btn btn-primary btn-xs">Upload the file</button>
Then, the script tag....
Dropzone.options.myAwesomeDropzone = { // The camelized version of the ID of the form element
// The configuration we've talked about above
autoProcessQueue: false,
uploadMultiple: true,
parallelUploads: 25,
maxFiles: 25,
// The setting up of the dropzone
init: function() {
var myDropzone = this;
// Here's the change from enyo's tutorial...
$("#submit-all").click(function (e) {
e.preventDefault();
e.stopPropagation();
myDropzone.processQueue();
});
}
}
I had a similar situation where I wanted to replace a URL query parameter. However, I only had one param, and I could simply replace it:
window.location.search = '?filter=' + my_filter_value
The location.search
property allows you to get or set the query portion of a URL.

export type InputChangeEventHandler = React.ChangeEventHandler<HTMLInputElement>
export type TextareaChangeEventHandler = React.ChangeEventHandler<HTMLTextAreaElement>
export type SelectChangeEventHandler = React.ChangeEventHandler<HTMLSelectElement>
Then import them:
import { InputChangeEventHandler } from '../types'
Then use them:
const updateName: InputChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
const updateBio: TextareaChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
const updateSize: SelectChangeEventHandler = (event) => {
// Do something with `event.currentTarget.value`
}
Then apply the functions on your markup (replacing ...
with other necessary props):
<input onChange={updateName} ... />
<textarea onChange={updateName} ... />
<select onChange={updateSize} ... >
// ...
</select>
If you've ever been saved by an Emacs backup file, you
probably want more of them, not less of them. It is annoying
that they go in the same directory as the file you're editing,
but that is easy to change. You can make all backup files go
into a directory by putting something like the following in your
.emacs
.
(setq backup-directory-alist `(("." . "~/.saves")))
There are a number of arcane details associated with how Emacs might create your backup files. Should it rename the original and write out the edited buffer? What if the original is linked? In general, the safest but slowest bet is to always make backups by copying.
(setq backup-by-copying t)
If that's too slow for some reason you might also have a look at
backup-by-copying-when-linked
.
Since your backups are all in their own place now, you might want
more of them, rather than less of them. Have a look at the Emacs
documentation for these variables (with C-h v
).
(setq delete-old-versions t
kept-new-versions 6
kept-old-versions 2
version-control t)
Finally, if you absolutely must have no backup files:
(setq make-backup-files nil)
It makes me sick to think of it though.
onPause()
method works in activity class you can use:
public void onDestroyView(){
super.onDestroyView
}
for same purpose..
X.each_with_index do |item, index|
puts "current_index: #{index}"
end
The combination that worked for me was:
Using atos I wasn't able to resolve the correct symbol information with the addresses and offsets that were in the crash report. When I did this, I see something more meaningful, and it seems to be a legitimate stack trace.
Use Supplier
if it takes nothing, but returns something.
Use Consumer
if it takes something, but returns nothing.
Use Callable
if it returns a result and might throw (most akin to Thunk
in general CS terms).
Use Runnable
if it does neither and cannot throw.
I had received a similar error message. Think I inadvertently typed "9o" at start of first line of php.ini file. Once I removed that, I no longer received the "fatal error" messages. Hope this helps.
Also, in the above case there should be only one
implicit function whose type is double => Int
. Otherwise, the compiler gets confused and won't compile properly.
//this won't compile
implicit def doubleToInt(d: Double) = d.toInt
implicit def doubleToIntSecond(d: Double) = d.toInt
val x: Int = 42.0
This answer is more of an example code. All the above answers give good explanations regarding why one should use partial. I will give my observations and use cases about partial.
from functools import partial
def adder(a,b,c):
print('a:{},b:{},c:{}'.format(a,b,c))
ans = a+b+c
print(ans)
partial_adder = partial(adder,1,2)
partial_adder(3) ## now partial_adder is a callable that can take only one argument
Output of the above code should be:
a:1,b:2,c:3
6
Notice that in the above example a new callable was returned that will take parameter (c) as it's argument. Note that it is also the last argument to the function.
args = [1,2]
partial_adder = partial(adder,*args)
partial_adder(3)
Output of the above code is also:
a:1,b:2,c:3
6
Notice that * was used to unpack the non-keyword arguments and the callable returned in terms of which argument it can take is same as above.
Another observation is: Below example demonstrates that partial returns a callable which will take the undeclared parameter (a) as an argument.
def adder(a,b=1,c=2,d=3,e=4):
print('a:{},b:{},c:{},d:{},e:{}'.format(a,b,c,d,e))
ans = a+b+c+d+e
print(ans)
partial_adder = partial(adder,b=10,c=2)
partial_adder(20)
Output of the above code should be:
a:20,b:10,c:2,d:3,e:4
39
Similarly,
kwargs = {'b':10,'c':2}
partial_adder = partial(adder,**kwargs)
partial_adder(20)
Above code prints
a:20,b:10,c:2,d:3,e:4
39
I had to use it when I was using Pool.map_async
method from multiprocessing
module. You can pass only one argument to the worker function so I had to use partial
to make my worker function look like a callable with only one input argument but in reality my worker function had multiple input arguments.
The other answers that involve writing a custom Collector
are probably more efficient (such as Louis Wasserman's, +1), but if you want brevity, I'd suggest the following:
List<User> result = users.stream()
.filter(user -> user.getId() == 1)
.limit(2)
.collect(Collectors.toList());
Then verify the size of the result list.
if (result.size() != 1) {
throw new IllegalStateException("Expected exactly one user but got " + result);
User user = result.get(0);
}
Simple math.
double result = ((double)number) / 100.0;
Although you may want to use decimal
rather than double
: decimal vs double! - Which one should I use and when?

Update 1: I changed my username. The link to the example is now https://github.com/Yannic92/stackOverflowExamples/tree/master/SpringBoot/MySQL
The server you're trying to download from may be badly configured. Even if it works in your browser, it may not be including all the public certificates in the chain needed for a cache-empty client to verify.
I recommend checking the site in SSLlabs tool: https://www.ssllabs.com/ssltest/
Look for this error:
This server's certificate chain is incomplete.
And this:

In iOS 11 there is a method that tells when the safeArea has changed.
override func viewSafeAreaInsetsDidChange() {
super.viewSafeAreaInsetsDidChange()
let top = view.safeAreaInsets.top
let bottom = view.safeAreaInsets.bottom
}
If you need wait until the ajax call is completed all do you need is make your call synchronously.
I had this issue with AOSP (clang).
Add external\libcxx\include
to includes and _LIBCPP_COMPILER_CLANG

TryGetValue is slightly faster, because FindEntry will only be called once.
How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.
FYI: It's not actually catching an error.
It's calling:
public bool TryGetValue(TKey key, out TValue value)
{
int index = this.FindEntry(key);
if (index >= 0)
{
value = this.entries[index].value;
return true;
}
value = default(TValue);
return false;
}
ContainsKey is this:
public bool ContainsKey(TKey key)
{
return (this.FindEntry(key) >= 0);
}
I know this is an old question, but I'd like to offer one example of how the yield keyword can be creatively used. I have really benefited from this technique. Hopefully this will be of assistance to anyone else who stumbles upon this question.
Note: Don't think about the yield keyword as merely being another way to build a collection. A big part of the power of yield comes in the fact that execution is paused in your method or property until the calling code iterates over the next value. Here's my example:
Using the yield keyword (alongside Rob Eisenburg's Caliburn.Micro coroutines implementation) allows me to express an asynchronous call to a web service like this:
public IEnumerable<IResult> HandleButtonClick() {
yield return Show.Busy();
var loginCall = new LoginResult(wsClient, Username, Password);
yield return loginCall;
this.IsLoggedIn = loginCall.Success;
yield return Show.NotBusy();
}
What this will do is turn my BusyIndicator on, call the Login method on my web service, set my IsLoggedIn flag to the return value, and then turn the BusyIndicator back off.
Here's how this works: IResult has an Execute method and a Completed event. Caliburn.Micro grabs the IEnumerator from the call to HandleButtonClick() and passes it into a Coroutine.BeginExecute method. The BeginExecute method starts iterating through the IResults. When the first IResult is returned, execution is paused inside HandleButtonClick(), and BeginExecute() attaches an event handler to the Completed event and calls Execute(). IResult.Execute() can perform either a synchronous or an asynchronous task and fires the Completed event when it's done.
LoginResult looks something like this:
public LoginResult : IResult {
// Constructor to set private members...
public void Execute(ActionExecutionContext context) {
wsClient.LoginCompleted += (sender, e) => {
this.Success = e.Result;
Completed(this, new ResultCompletionEventArgs());
};
wsClient.Login(username, password);
}
public event EventHandler<ResultCompletionEventArgs> Completed = delegate { };
public bool Success { get; private set; }
}
It may help to set up something like this and step through the execution to watch what's going on.
Hope this helps someone out! I've really enjoyed exploring the different ways yield can be used.
This is a few months late but I thought I'd provide my solution based on this here tutorial. The gist of it is that it's a lot easier to manage once you change the way you approach forms.
First, use ReactiveFormsModule
instead of or in addition to the normal FormsModule
. With reactive forms you create your forms in your components/services and then plug them into your page instead of your page generating the form itself. It's a bit more code but it's a lot more testable, a lot more flexible, and as far as I can tell the best way to make a lot of non-trivial forms.
The end result will look a little like this, conceptually:
You have one base FormGroup
with whatever FormControl
instances you need for the entirety of the form. For example, as in the tutorial I linked to, lets say you want a form where a user can input their name once and then any number of addresses. All of the one-time field inputs would be in this base form group.
Inside that FormGroup
instance there will be one or more FormArray
instances. A FormArray
is basically a way to group multiple controls together and iterate over them. You can also put multiple FormGroup
instances in your array and use those as essentially "mini-forms" nested within your larger form.
By nesting multiple FormGroup
and/or FormControl
instances within a dynamic FormArray
, you can control validity and manage the form as one, big, reactive piece made up of several dynamic parts. For example, if you want to check if every single input is valid before allowing the user to submit, the validity of one sub-form will "bubble up" to the top-level form and the entire form becomes invalid, making it easy to manage dynamic inputs.
As a FormArray
is, essentially, a wrapper around an array interface but for form pieces, you can push, pop, insert, and remove controls at any time without recreating the form or doing complex interactions.
In case the tutorial I linked to goes down, here some sample code you can implement yourself (my examples use TypeScript) that illustrate the basic ideas:
Base Component code:
import { Component, Input, OnInit } from '@angular/core';
import { FormArray, FormBuilder, FormGroup, Validators } from '@angular/forms';
@Component({
selector: 'my-form-component',
templateUrl: './my-form.component.html'
})
export class MyFormComponent implements OnInit {
@Input() inputArray: ArrayType[];
myForm: FormGroup;
constructor(private fb: FormBuilder) {}
ngOnInit(): void {
let newForm = this.fb.group({
appearsOnce: ['InitialValue', [Validators.required, Validators.maxLength(25)]],
formArray: this.fb.array([])
});
const arrayControl = <FormArray>newForm.controls['formArray'];
this.inputArray.forEach(item => {
let newGroup = this.fb.group({
itemPropertyOne: ['InitialValue', [Validators.required]],
itemPropertyTwo: ['InitialValue', [Validators.minLength(5), Validators.maxLength(20)]]
});
arrayControl.push(newGroup);
});
this.myForm = newForm;
}
addInput(): void {
const arrayControl = <FormArray>this.myForm.controls['formArray'];
let newGroup = this.fb.group({
/* Fill this in identically to the one in ngOnInit */
});
arrayControl.push(newGroup);
}
delInput(index: number): void {
const arrayControl = <FormArray>this.myForm.controls['formArray'];
arrayControl.removeAt(index);
}
onSubmit(): void {
console.log(this.myForm.value);
// Your form value is outputted as a JavaScript object.
// Parse it as JSON or take the values necessary to use as you like
}
}
Sub-Component Code: (one for each new input field, to keep things clean)
import { Component, Input } from '@angular/core';
import { FormGroup } from '@angular/forms';
@Component({
selector: 'my-form-sub-component',
templateUrl: './my-form-sub-component.html'
})
export class MyFormSubComponent {
@Input() myForm: FormGroup; // This component is passed a FormGroup from the base component template
}
Base Component HTML
<form [formGroup]="myForm" (ngSubmit)="onSubmit()" novalidate>
<label>Appears Once:</label>
<input type="text" formControlName="appearsOnce" />
<div formArrayName="formArray">
<div *ngFor="let control of myForm.controls['formArray'].controls; let i = index">
<button type="button" (click)="delInput(i)">Delete</button>
<my-form-sub-component [myForm]="myForm.controls.formArray.controls[i]"></my-form-sub-component>
</div>
</div>
<button type="button" (click)="addInput()">Add</button>
<button type="submit" [disabled]="!myForm.valid">Save</button>
</form>
Sub-Component HTML
<div [formGroup]="form">
<label>Property One: </label>
<input type="text" formControlName="propertyOne"/>
<label >Property Two: </label>
<input type="number" formControlName="propertyTwo"/>
</div>
In the above code I basically have a component that represents the base of the form and then each sub-component manages its own FormGroup
instance within the FormArray
situated inside the base FormGroup
. The base template passes along the sub-group to the sub-component and then you can handle validation for the entire form dynamically.
Also, this makes it trivial to re-order component by strategically inserting and removing them from the form. It works with (seemingly) any number of inputs as they don't conflict with names (a big downside of template-driven forms as far as I'm aware) and you still retain pretty much automatic validation. The only "downside" of this approach is, besides writing a little more code, you do have to relearn how forms work. However, this will open up possibilities for much larger and more dynamic forms as you go on.
If you have any questions or want to point out some errors, go ahead. I just typed up the above code based on something I did myself this past week with the names changed and other misc. properties left out, but it should be straightforward. The only major difference between the above code and my own is that I moved all of the form-building to a separate service that's called from the component so it's a bit less messy.
hashMaps
can't have duplicate keys. That said, you can create a map with list values:
Map<Integer, List<String>>
However, using this approach will have performance implications.
You should use something like this pg_dump --schema=your_schema_name db1
, for details take a look here
You can simply use multiprocessing.Pool
:
from multiprocessing import Pool
def process_image(name):
sci=fits.open('{}.fits'.format(name))
<process>
if __name__ == '__main__':
pool = Pool() # Create a multiprocessing Pool
pool.map(process_image, data_inputs) # process data_inputs iterable with pool
So actually, my comment that you should do a console.log(el.nativeElement)
should have pointed you in the right direction, but I didn't expect the output to be just a string representing the DOM Element
.
What you have to do to inspect it in the way it helps you with your problem, is to do a console.log(el)
in your example, then you'll have access to the nativeElement
object and will see a property called innerHTML
.
Which will lead to the answer to your original question:
let myCurrentContent:string = el.nativeElement.innerHTML; // get the content of your element
el.nativeElement.innerHTML = 'my new content'; // set content of your element
Since it's the accepted answer and web workers are getting more important day to day (and it's considered best practice anyway) I want to add this suggestion by Mark Rajcok here.
The best way to manipulate DOM Elements
programmatically is using the Renderer:
constructor(private _elemRef: ElementRef, private _renderer: Renderer) {
this._renderer.setElementProperty(this._elemRef.nativeElement, 'innerHTML', 'my new content');
}
Since Renderer
is deprecated now, use Renderer2 instead with setProperty
This question with its answer explained the console.log
behavior.
Which means that console.dir(el.nativeElement)
would be the more direct way of accessing the DOM Element
as an "inspectable" Object in your console for this situation.
Hope this helped.
Nothing worked for me except, I loggined using pgAdmin4 and on the Dashboard I disconnected all connections except pgAdmin4 and then was able to rename by right lick on the database and properties and typed new name.
npm uninstall yarn removes the yarn packages that are installed via npm but what yarn does underneath the hood is, it installs a software named yarn in your PC. If you have installed in Windows, Go to add or remove programs and then search for yarn and uninstall it then you are good to go.
I'm probably late but this worked for me:

Java 8 solution for produce string like "key1: value1,key2: value2"
private static String hashMapToString(HashMap<String, String> hashMap) {
return hashMap.keySet().stream()
.map((key) -> key + ": " + hashMap.get(key))
.collect(Collectors.joining(","));
}
and produce a list simple collect as list
private static List<String> hashMapToList(HashMap<String, String> hashMap) {
return hashMap.keySet().stream()
.map((key) -> key + ": " + hashMap.get(key))
.collect(Collectors.toList());
}
In case you don't want/need to post:
@Html.ActionLink("link caption", "actionName", new { Model.Page }) // view's controller
@Html.ActionLink("link caption", "actionName", "controllerName", new { reportID = 1 }, null);
[HttpGet]
public ActionResult actionName(int reportID)
{
Note that the reportID in the new {} part matches reportID in the action parameters, you can add any number of parameters this way, but any more than 2 or 3 (some will argue always) you should be passing a model via a POST (as per other answer)
Edit: Added null for correct overload as pointed out in comments. There's a number of overloads and if you specify both action+controller, then you need both routeValues and htmlAttributes. Without the controller (just caption+action), only routeValues are needed but may be best practice to always specify both.
They're faster; unless you're loading the entire flat file into memory, a database will allow faster access in almost all cases.
They're safer; databases are easier to safely backup; they have mechanisms to check for file corruption, which flat files do not. Once corruption in your flat file migrates to your backups, you're done, and you might not even know it yet.
They have more features; databases can allow many users to read/write at the same time.
They're much less complex to work with, once they're setup.
Now visibility change animations should be done via Transition API
which available in support (androidx) package. Just call TransitionManager.beginDelayedTransition method with Slide transition then change visibility of the view.
import androidx.transition.Slide;
import androidx.transition.Transition;
import androidx.transition.TransitionManager;
private void toggle(boolean show) {
View redLayout = findViewById(R.id.redLayout);
ViewGroup parent = findViewById(R.id.parent);
Transition transition = new Slide(Gravity.BOTTOM);
transition.setDuration(600);
transition.addTarget(R.id.redLayout);
TransitionManager.beginDelayedTransition(parent, transition);
redLayout.setVisibility(show ? View.VISIBLE : View.GONE);
}
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>

Check this answer with another default and custom transition examples.
One of other differences is kmalloc will return logical address (else you specify GPF_HIGHMEM). Logical addresses are placed in "low memory" (in the first gigabyte of physical memory) and are mapped directly to physical addresses (use __pa macro to convert it). This property implies kmalloced memory is continuous memory.
In other hand, Vmalloc is able to return virtual addresses from "high memory". These addresses cannot be converted in physical addresses in a direct fashion (you have to use virt_to_page function).
A HashSet
has an internal structure (hash), where items can be searched and identified quickly. The downside is that iterating through a HashSet
(or getting an item by index) is rather slow.
So why would someone want be able to know if an entry already exists in a set?
One situation where a HashSet
is useful is in getting distinct values from a list where duplicates may exist. Once an item is added to the HashSet
it is quick to determine if the item exists (Contains
operator).
Other advantages of the HashSet
are the Set operations: IntersectWith
, IsSubsetOf
, IsSupersetOf
, Overlaps
, SymmetricExceptWith
, UnionWith
.
If you are familiar with the object constraint language then you will identify these set operations. You will also see that it is one step closer to an implementation of executable UML.
Maybe just an OR operator |
could be enough for your problem:
String: foo,bar,baz
Regex: (foo)|(baz)
Result: ["foo", "baz"]
colrm x
For example, if you need the first 100 characters:
cat file |colrm 101
It's been around for years and is in most linux's and bsd's (freebsd for sure), usually by default. I can't remember ever having to type apt-get install colrm
.
A nice technique i've started using with some of my apps on express is to create an object which merges the query, params, and body fields of express's request object.
//./express-data.js
const _ = require("lodash");
class ExpressData {
/*
* @param {Object} req - express request object
*/
constructor (req) {
//Merge all data passed by the client in the request
this.props = _.merge(req.body, req.params, req.query);
}
}
module.exports = ExpressData;
Then in your controller body, or anywhere else in scope of the express request chain, you can use something like below:
//./some-controller.js
const ExpressData = require("./express-data.js");
const router = require("express").Router();
router.get("/:some_id", (req, res) => {
let props = new ExpressData(req).props;
//Given the request "/592363122?foo=bar&hello=world"
//the below would log out
// {
// some_id: 592363122,
// foo: 'bar',
// hello: 'world'
// }
console.log(props);
return res.json(props);
});
This makes it nice and handy to just "delve" into all of the "custom data" a user may have sent up with their request.
Note
Why the 'props' field? Because that was a cut-down snippet, I use this technique in a number of my APIs, I also store authentication / authorisation data onto this object, example below.
/*
* @param {Object} req - Request response object
*/
class ExpressData {
/*
* @param {Object} req - express request object
*/
constructor (req) {
//Merge all data passed by the client in the request
this.props = _.merge(req.body, req.params, req.query);
//Store reference to the user
this.user = req.user || null;
//API connected devices (Mobile app..) will send x-client header with requests, web context is implied.
//This is used to determine how the user is connecting to the API
this.client = (req.headers) ? (req.headers["x-client"] || (req.client || "web")) : "web";
}
}
Maybe too many years late, but nevertheless a theory to try.
The ratio of bounding rectangle of red logo region to the overall dimension of the bottle/can is different. In the case of Can, should be 1:1, whereas will be different in that of bottle (with or without cap). This should make it easy to distinguish between the two.
Update: The horizontal curvature of the logo region will be different between the Can and Bottle due their respective size difference. This could be specifically useful if your robot needs to pick up can/bottle, and you decide the grip accordingly.
Do not forget to exclude carriage returns from your data !!!
as in:
SELECT
Myotherval
, CASE WHEN TRIM(REPLACE([MyVal], char(13) + char(10), '')) not like '%[^0-9]%' and RTRIM(REPLACE([MyVal], char(13) + char(10), '')) not like '.' and isnumeric(REPLACE([MyVal], char(13) + char(10), '')) = 1 THEN 'my number: ' + [MyVal]
ELSE ISNULL(Cast([MyVal] AS VARCHAR(8000)), '')

In addition to the Eclipse solutions and the tool mentioned in another answer, consider flip. It can 'flip' either way between normal and Windows linebreaks, and does nice things like preserve the file's timestamp and other stats.
You can use it like this to solve your problem:
find . -type f -not -path './.git/*' -exec flip -u {} \;
(I put in a clause to ignore your .git directory, in case you use git, but since flip ignores binary files by default, you mightn't need this.)
For individual variables you want to make available on a one off basis you can make it part of the command.
