There's another solution that also works.
This works because you have multiple classes in different jar files. Removing and re-adding the JRE lib will make the right classes be first. If you want a fundamental solution make sure you exclude the jar files with the same classes.
For me I have: javax.xml.soap.SOAPPart
in three different jars: axis-saaj-1.4.jar
, saaj-api-1.3.jar
and the rt.jar
Number (1): The IP was incorrect - is the correct answer. The /etc/hosts file (a.k.a. C:\Windows\system32\drivers\etc\hosts ) had an incorrect entry for the local machine name. Corrected the 'hosts' file and Camel runs very well. Thanks for the pointer.

I like the explanantion put out by Roy Osherove [video link].
Every class or object created is a Fake. It is a Mock if you verify calls against it. Otherwise its a stub.
url
prop is deprecated as of Next.js version 6:
https://github.com/zeit/next.js/blob/master/errors/url-deprecated.md
To get the query parameters, use getInitialProps
:
import Link from 'next/link'
const About = ({query}) => (
<div>Click <Link href={{ pathname: 'about', query: { name: 'leangchhean' }}}><a>here</a></Link> to read more</div>
)
About.getInitialProps = ({query}) => {
return {query}
}
export default About;
class About extends React.Component {
static getInitialProps({query}) {
return {query}
}
render() {
console.log(this.props.query) // The query is available in the props object
return <div>Click <Link href={{ pathname: 'about', query: { name: 'leangchhean' }}}><a>here</a></Link> to read more</div>
}
}
The query object will be like: url.com?a=1&b=2&c=3
becomes: {a:1, b:2, c:3}
None of the above answers were complete for me.
If your field is named field
, so the selector should be the following one:
IFNULL(`field`,0) AS field
For example in a SELECT query:
SELECT IFNULL(`field`,0) AS field, `otherfield` FROM `mytable`
Hope this can help someone to not waste time.
const mongoose = require('mongoose');
const config = require('config');
const util = require('util');
const Schema = mongoose.Schema;
const BaseSchema = function(obj, options) {
if (typeof(options) == 'undefined') {
options = {};
}
if (typeof(options['timestamps']) == 'undefined') {
options['timestamps'] = true;
}
Schema.apply(this, [obj, options]);
};
util.inherits(BaseSchema, Schema);
var testSchema = new BaseSchema({
jsonObject: { type: Object }
, stringVar : { type: String }
});
Now you can use this, so that there is no need to include this option in every table
You can just add a main
function to resolve this problem.
Just like:
int main()
{
return 0;
}
You could also use in_array as follows:
<?php
$found = null;
$people = array(3,20,2);
$criminals = array( 2, 4, 8, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20);
foreach($people as $num) {
if (in_array($num,$criminals)) {
$found[$num] = true;
}
}
var_dump($found);
// array(2) { [20]=> bool(true) [2]=> bool(true) }
While array_intersect is certainly more convenient to use, it turns out that its not really superior in terms of performance. I created this script too:
<?php
$found = null;
$people = array(3,20,2);
$criminals = array( 2, 4, 8, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20);
$fastfind = array_intersect($people,$criminals);
var_dump($fastfind);
// array(2) { [1]=> int(20) [2]=> int(2) }
Then, I ran both snippets respectively at: http://3v4l.org/WGhO7/perf#tabs and http://3v4l.org/g1Hnu/perf#tabs and checked the performance of each. The interesting thing is that the total CPU time, i.e. user time + system time is the same for PHP5.6 and the memory also is the same. The total CPU time under PHP5.4 is less for in_array than array_intersect, albeit marginally so.
"Segmentation fault" means that you tried to access memory that you do not have access to.
The first problem is with your arguments of main
. The main
function should be int main(int argc, char *argv[])
, and you should check that argc
is at least 2 before accessing argv[1]
.
Also, since you're passing in a float
to printf
(which, by the way, gets converted to a double
when passing to printf
), you should use the %f
format specifier. The %s
format specifier is for strings ('\0'
-terminated character arrays).
I use this routine to find the count of data rows. There is a minimum of overhead required, but by counting using a decreasing scale, even a very large result requires few iterations. For example, a result of 28,395 would only require 2 + 8 + 3 + 9 + 5, or 27 times through the loop, instead of a time-expensive 28,395 times.
Even were we to multiply that by 10 (283,950), the iteration count is the same 27 times.

My friend and I just had this argument: What is the difference between a programming language and a scripting language.
A popular argument is that programming languages are compiled and scripting languages are interpreted - However I believe this argument to be completely false...why?
On that basis, this is my argument for the difference between a programming language and a scripting language:
A programming language runs at the machine level and has access to the machine itself (memory, graphics, sound etc).
A scripting language is sand boxed and only has access to objects exposed to the sand box. It has no direct access to the underlying machine.
If you want to set environment variables permanently in Git-Bash, you have two options:
Set a regular Windows environment variable. Git-bash gets all existing Windows environment variables at startupp.
Set up env variables in .bash_profile
file.
.bash_profile
is by default located in a user home folder, like C:\users\userName\git-home\.bash_profile
. You can change the path to the bash home folder by setting HOME
Windows environment variable.
.bash_profile
file uses the regular Bash syntax and commands
# Export a variable in .bash_profile
export DIR=c:\dir
# Nix path style works too
export DIR=/c/dir
# And don't forget to add quotes if a variable contains whitespaces
export ANOTHER_DIR="c:\some dir"
Read more information about Bash configurations files.
You can't call a Javascript function from the CodeBehind, because the CodeBehind file contains the code that executes server side on the web server. Javascript code executes in the web browser on the client side.
The best way (actually the only way*) to simulate an actual click event using only CSS (rather than just hovering on an element or making an element active, where you don't have mouseUp) is to use the checkbox hack. It works by attaching a label
to an <input type="checkbox">
element via the label's for=""
attribute.
This feature has broad browser support (the :checked
pseudo-class is IE9+).
Apply the same value to an <input>
's ID attribute and an accompanying <label>
's for=""
attribute, and you can tell the browser to re-style the label on click with the :checked
pseudo-class, thanks to the fact that clicking a label will check and uncheck the "associated" <input type="checkbox">
.
* You can simulate a "selected" event via the :active
or :focus
pseudo-class in IE7+ (e.g. for a button that's normally 50px
wide, you can change its width while active
: #btnControl:active { width: 75px; }
), but those are not true "click" events. They are "live" the entire time the element is selected (such as by Tabbing with your keyboard), which is a little different from a true click event, which fires an action on - typically - mouseUp
.
label {
display: block;
background: lightgrey;
width: 100px;
height: 100px;
}
#demo:checked + label {
background: blue;
color: white;
}
_x000D_
<input type="checkbox" id="demo"/>
<label for="demo">I'm a square. Click me.</label>
_x000D_
Here I've positioned the label right after the input in my markup. This is so that I can use the adjacent sibling selector (the + key) to select only the label that immediately follows my #demo
checkbox. Since the :checked
pseudo-class applies to the checkbox, #demo:checked + label
will only apply when the checkbox is checked.
#btnControl {
display: none;
}
#btnControl:checked + label > img {
width: 70px;
height: 74px;
}
_x000D_
<input type="checkbox" id="btnControl"/>
<label class="btn" for="btnControl"><img src="https://placekitten.com/200/140" id="btnLeft" /></label>
_x000D_
With that being said, there is some bad news. Because a label can only be associated with one form control at a time, that means you can't just drop a button inside the <label></label>
tags and call it a day. However, we can use some CSS to make the label look and behave fairly close to how an HTML button looks and behaves.
#btnControl {
display: none;
}
.btn {
width: 60px;
height: 20px;
background: silver;
border-radius: 5px;
padding: 1px 3px;
box-shadow: 1px 1px 1px #000;
display: block;
text-align: center;
background-image: linear-gradient(to bottom, #f4f5f5, #dfdddd);
font-family: arial;
font-size: 12px;
line-height:20px;
}
.btn:hover {
background-image: linear-gradient(to bottom, #c3e3fa, #a5defb);
}
.btn:active {
margin-left: 1px 1px 0;
box-shadow: -1px -1px 1px #000;
outline: 1px solid black;
-moz-outline-radius: 5px;
background-image: linear-gradient(to top, #f4f5f5, #dfdddd);
}
#btnControl:checked + label {
width: 70px;
height: 74px;
line-height: 74px;
}
_x000D_
<input type="checkbox" id="btnControl"/>
<label class="btn" for="btnControl">Click me!</label>
_x000D_
Most of the CSS in this demo is just for styling the label element. If you don't actually need a button, and any old element will suffice, then you can remove almost all of the styles in this demo, similar to my second demo above.
You'll also notice I have one prefixed property in there, -moz-outline-radius
. A while back, Mozilla added this awesome non-spec property to Firefox, but the folks at WebKit decided they aren't going to add it, unfortunately. So consider that line of CSS just a progressive enhancement for people who use Firefox.
Reading binary Word documents would involve creating a parser according to the published file format specifications for the DOC format. I think this is no real feasible solution.
You could use the Microsoft Office XML formats for reading and writing Word files - this is compatible with the 2003 and 2007 version of Word. For reading you have to ensure that the Word documents are saved in the correct format (it's called Word 2003 XML-Document in Word 2007). For writing you just have to follow the openly available XML schema. I've never used this format for writing out Office documents from PHP, but I'm using it for reading in an Excel worksheet (naturally saved as XML-Spreadsheet 2003) and displaying its data on a web page. As the files are plainly XML data it's no problem to navigate within and figure out how to extract the data you need.
The other option - a Word 2007 only option (if the OpenXML file formats are not installed in your Word 2003) - would be to ressort to OpenXML. As databyss pointed out here the DOCX file format is just a ZIP archive with XML files included. There are a lot of resources on MSDN regarding the OpenXML file format, so you should be able to figure out how to read the data you want. Writing will be much more complicated I think - it just depends on how much time you'll invest.
Perhaps you can have a look at PHPExcel which is a library able to write to Excel 2007 files and read from Excel 2007 files using the OpenXML standard. You could get an idea of the work involved when trying to read and write OpenXML Word documents.
Thanks to https://stackoverflow.com/users/1652962/cimmanon that gave me the answer.
The solution is setting a height to the vertical scrollable element. For example:
#container article {
flex: 1 1 auto;
overflow-y: auto;
height: 0px;
}
The element will have height because flexbox recalculates it unless you want a min-height so you can use height: 100px;
that it is exactly the same as: min-height: 100px;
#container article {
flex: 1 1 auto;
overflow-y: auto;
height: 100px; /* == min-height: 100px*/
}
So the best solution if you want a min-height
in the vertical scroll:
#container article {
flex: 1 1 auto;
overflow-y: auto;
min-height: 100px;
}
If you just want full vertical scroll in case there is no enough space to see the article:
#container article {
flex: 1 1 auto;
overflow-y: auto;
min-height: 0px;
}
The final code: http://jsfiddle.net/ch7n6/867/
1- you need to close the block of the function with '}', which is missing.
2- the argument of querySelector may not be an empty string '' or ' '... Use '*' for all.
3- those arguments will return the needed value:
querySelector('*')
querySelector('input')
querySelector('input[name="pwd"]')
querySelector('[name="pwd"]')
This is good Angular plugin for uploading files, and its free!
setting the overflow
should take care of it, but you need to set the height of Content
also. If the height attribute is not set, the div will grow vertically as tall as it needs to, and scrollbars wont be needed.
See Example: http://jsfiddle.net/ftkbL/1/
I accidentally encoded a file in UTF-7 and had a similar issue. When I typed file -i name.file
I would get charset=us-ascii
.
iconv -f us-ascii -t utf-9//translit name.file
would not work since I've gathered UTF-7 is a subset of US ASCII, as is UTF-8.
To solve this, I entered
iconv -f UTF-7 -t UTF-8//TRANSLIT name.file -o output.file
I'm not sure how to determine the encoding other than what others have suggested here.
You just need one line:
ImageViewer1.Source = new BitmapImage(new Uri(@"\myserver\folder1\Customer Data\sample.png"));
For Python 3.6+ sudo apt-get install libmysqlclient-dev

does the trick
Builder and Abstract Factory have meant for different purposes. Depending on right use case, you have to select suitable design pattern.
Builder salient features:
Factory (simple Factory) salient features:
Often, designs start out using Factory Method (less complicated, more customizable, subclasses proliferate) and evolve toward Abstract Factory, Prototype, or Builder (more flexible, more complex)
Have a look at related posts:
Keeping builder in separate class (fluent interface)
Design Patterns: Factory vs Factory method vs Abstract Factory
You can refer to below articles for more details:
Store a reference to the meter instance as a member in Production:
public class Production {
//The other members, properties etc...
private Meter m;
Production(Meter m) {
this.m = m;
}
}
And then in the Meter-class:
public class Meter
{
private int _powerRating = 0;
private Production _production;
public Meter()
{
_production = new Production(this);
}
}
Also note that you need to implement an accessor method/property so that the Production class can actually access the powerRating member of the Meter class.
when you construct yours strings it should be like this
bool inact = new string[] { "SUSPENDARE", "DIZOLVARE" }.Any(s=>stare.Contains(s));
with(dfr[dfr$var3 < 155,], plot(var1, var2))
should do the trick.
Edit regarding multiple conditions:
with(dfr[(dfr$var3 < 155) & (dfr$var4 > 27),], plot(var1, var2))
You would use the WITH ADMIN OPTION
option in the GRANT
statement
GRANT CREATE SESSION TO <<username>> WITH ADMIN OPTION
You are assigning reloaded items to global variable items in onResume()
, but this will not reflect in ItemAdapter
class, because it has its own instance variable called 'items'.
For refreshing ListView
, add a refresh() in ItemAdapter
class which accepts list data i.e items
class ItemAdapter
{
.....
public void refresh(List<Item> items)
{
this.items = items;
notifyDataSetChanged();
}
}
update onResume()
with following code
@Override
public void onResume()
{
super.onResume();
items.clear();
items = dbHelper.getItems(); //reload the items from database
**adapter.refresh(items);**
}
Another way without using the .form-control is this:
$(".dropdown-menu li a").click(function(){
$(this).parents(".btn-group").find('.btn').html($(this).text() + ' <span class="caret"></span>');
$(this).parents(".btn-group").find('.btn').val($(this).data('value'));
});
$(".dropdown-menu li a").click(function(){_x000D_
$(this).parents(".btn-group").find('.btn').html($(this).text() + ' <span class="caret"></span>');_x000D_

It's not in standard C, so the behavior is undefined.
Some implementation uses it to clear stdin
buffer.
From C11 7.21.5.2 The fflush function, fflush
works only with output/update stream, not input stream.
If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.
simply don't close in
remove in.close()
from your code.
THis is other method
You can also use setCenter
method with add new marker
check below code
$('#my_map').gmap3({
action: 'setCenter',
map:{
options:{
zoom: 10
}
},
marker:{
values:
[
{latLng:[position.coords.latitude, position.coords.longitude], data:"Netherlands !"}
]
}
});
This can happen with symlinks sometimes. If you experience this issue and you know you are in an existing directory, but your symlink may have changed, you can use this command:
cd $(pwd)
This is not a good way when you want to seeding database.
Use faker instead of hard coding, and before all this maybe it's better to truncate tables.
Consider this example :
// Truncate table.
DB::table('users')->truncate();
// Create an instance of faker.
$faker = Faker::create();
// define an array for fake data.
$users = [];
// Make an array of 500 users with faker.
foreach (range(1, 500) as $index)
{
$users[] = [
'group_id' => rand(1, 3),
'name' => $faker->name,
'company' => $faker->company,
'email' => $faker->email,
'phone' => $faker->phoneNumber,
'address' => "{$faker->streetName} {$faker->postCode} {$faker->city}",
'about' => $faker->sentence($nbWords = 20, $variableNbWords = true),
'created_at' => new DateTime,
'updated_at' => new DateTime,
];
}
// Insert into database.
DB::table('users')->insert($users);
var model = JSON.stringify({
'ID': 0,
'ProductID': $('#ID').val(),
'PartNumber': $('#part-number').val(),
'VendorID': $('#Vendors').val()
})
$.ajax({
type: "POST",
dataType: "json",
contentType: "application/json",
url: "/api/PartSourceAPI/",
data: model,
success: function (data) {
alert('success');
},
error: function (error) {
jsonValue = jQuery.parseJSON(error.responseText);
jError('An error has occurred while saving the new part source: ' + jsonValue, { TimeShown: 3000 });
}
});
var model = JSON.stringify({ 'ID': 0, ...': 5, 'PartNumber': 6, 'VendorID': 7 }) // output is "{"ID":0,"ProductID":5,"PartNumber":6,"VendorID":7}"
your data is something like this "{"model": "ID":0,"ProductID":6,"PartNumber":7,"VendorID":8}}" web api controller cannot bind it to Your model

I finally discover the error. The problem is that the primary key constraint name is equal the table name. I don know how postgres represents constraints, but I think the error "Relation already exists" was being triggered during the creation of the primary key constraint because the table was already declared. But because of this error, the table wasnt created at the end.

UPDATE: Since this answer was written, Visibility
was introduced and provides the best solution to this problem.
You can use Opacity
with an opacity:
of 0.0
to draw make an element hidden but still occupy space.
To make it not occupy space, replace it with an empty Container()
.
EDIT: To wrap it in an Opacity object, do the following:
new Opacity(opacity: 0.0, child: new Padding(
padding: const EdgeInsets.only(
left: 16.0,
),
child: new Icon(pencil, color: CupertinoColors.activeBlue),
))

C++11 has another (imperfect) option:

def approximate_size(size, flag_1024_or_1000=True):
mult = 1024 if flag_1024_or_1000 else 1000
for unit in UNITS[mult]:
size = size / mult
if size < mult:
return '{0:.3f} {1}'.format(size, unit)

you can use Package Manager to add it as package and it is the easiest way to do. You don't need anything else to work with mysql database.
Or you can run below command in Package Manager Console
PM> Install-Package MySql.Data
$lastMonth = date('M Y', strtotime("-1 month"));
var_dump($lastMonth);
$lastMonth = date('M Y', mktime(0, 0, 0, date('m') - 1, 1, date('Y')));
var_dump($lastMonth);
Go to your project's properties and set the start page property.
In addition to options suggested by others I can recommend the fmt library which implements string formatting similar to str.format
in Python and String.Format
in C#. Here's an example:
std::string a = "test";
std::string b = "text.txt";
std::string c = "text1.txt";
std::string result = fmt::format("{0} {1} > {2}", a, b, c);
Disclaimer: I'm the author of this library.
try as this code.
$.ajax({
type: "POST",
url: "http://rt.ja.com/includes/register.php?submit=1",
data: "username="+username+"&email="+email+"&password="+password+"&passconf="+passconf,
success: function(html)
{
//alert(html);
$('#userError').html(html);
$("#userError").html(userChar);
$("#userError").html(userTaken);
}
});
i think this will work definitely..
you can also use .serialize() function for sending data via jquery Ajax..
i.e: data : $("#registerSubmit").serialize()
Thanks.
There's also ROUND() if your numbers don't necessarily always end with .00. ROUND(20.6) will give 21, and ROUND(20.4) will give 20.
I bet (no language specified) size()

However valid for

If you need to stretch your background image while resizing the screen and you don't need compatibility with older browser versions this will do the work:
body {
background-image: url('../images/image.jpg');
background-repeat: no-repeat;
background-size: cover;
}
ASP.NET always generate asp:Button
as an input type=submit
.
If you want a button which doesn't do a post, but need some control for the element on the server side, create a simple HTML input with attributes type=button
and runat=server
.
If you disable click actions doing OnClientClick=return false
, it won't do anything on click, unless you create a function like:
function btnClick() {
// do stuff
return false;
}
for windows use &
in between command also. Like,
"scripts": {
"start": "SET NODE_ENV=development & nodemon app/app.js",
}
You can use gcc/clang's unused attribute, however I use these macros in a header to avoid having gcc specific attributes all over the source, also having __attribute__

#endif
#ifdef __GNUC__
# define UNUSED_FUNCTION(x) __attribute__((__unused__)) UNUSED_ ## x
#else
# define UNUSED_FUNCTION(x) UNUSED_ ## x
#endif
Then you can do...
void foo(int UNUSED(bar)) { ... }
I prefer this because you get an error if you try use bar
in the code anywhere so you can't leave the attribute in by mistake.
and for functions...
static void UNUSED_FUNCTION(foo)(int bar) { ... }
Note 1):
As far as I know, MSVC doesn't have an equivalent to __attribute__((__unused__))
.
Note 2):
The UNUSED
macro won't work for arguments which contain parenthesis,
so if you have an argument like float (*coords)[3]
you can't do,float UNUSED((*coords)[3])
or float (*UNUSED(coords))[3]
, This is the only downside to the UNUSED
macro I found so far, in these cases I fall back to (void)coords;
You can install android-sdk in different ways
homebrew
Install brew using command from brew.sh
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Install android-sdk
using
brew install android-sdk
Now android-sdk
will be installed in /usr/local/opt/android-sdk
export ANDROID_HOME=/usr/local/opt/android-sdk
If you installed android studio following the website,
android-sdk
will be installed in ~/Library/Android/sdk
export ANDROID_HOME=~/Library/Android/sdk
I think these defaults make sense and its better to stick to it

allocationSize=1
It is a micro optimization before getting query Hibernate tries to assign value in the range of allocationSize and so try to avoid querying database for sequence. But this query will be executed every time if you set it to 1. This hardly makes any difference since if your data base is accessed by some other application then it will create issues if same id is used by another application meantime .
Next generation of Sequence Id is based on allocationSize.
By defualt it is kept as 50
which is too much. It will also only help if your going to have near about 50
records in one session which are not persisted and which will be persisted using this particular session and transation.
So you should always use allocationSize=1
while using SequenceGenerator
. As for most of underlying databases sequence is always incremented by 1
.
Try this: parseInt(jQuery.offset().top, 10)

You can change the listen port as per your requirement. This task can be accomplished in two diffrent ways. By changing config.xml file By changing in admin console Change the listen port in config.xml as per your requirement and bounce the domain. Admin Console Login to AdminConsole->Server->Configuration->ListenPort (Change it) Note: It is a bad practice to edit config.xml and try to edit in admin console(It's a good practise as well)

I try to avoid a few things when using Git.
Using knowledge of the internals, e.g. refs/tags. I try to use solely the documented Git commands and avoid using things which require knowledge of the internal contents of the .git directory. (That is to say, I treat Git as a Git user and not a Git developer.)
The use of force when not required.
Overdoing things. (Pushing a branch and/or lots of tags, to get one tag where I want it.)
So here is my non-violent solution for changing a tag, both locally and remotely, without knowledge of the Git internals.
I use it when a software fix ultimately has a problem and needs to be updated/re-released.
git tag -d fix123 # delete the old local tag
git push github :fix123 # delete the old remote tag (use for each affected remote)
git tag fix123 790a621265 # create a new local tag
git push github fix123 # push new tag to remote (use for each affected remote)
github
is a sample remote name, fix123
is a sample tag name, and 790a621265
a sample commit.
An update to @rleelr:
It's possible to view proxy settings in Google Chrome:
chrome://net-internals/#http2
Then select
View live HTTP/2 sessions
Then select one of the live sessions (you need to have some tabs open). There you find:
[...]
t=504112 [st= 0] +HTTP2_SESSION [dt=?]
--> host = "play.google.com:443"
--> proxy = "PROXY www.xxx.yyy.zzz:8080"
[...]
============================
It's important to distinguish two different formats:
The HTML5 specification does not include any means of overriding or manually specifying either format.
There are three basic options:
1) If retrieval performance is paramount and it is practical to do so, use a form of hash table built once (and altered as/if the List changes).
2) If the List is conveniently sorted or it is practical to sort it and O(log n) retrieval is sufficient, sort and search.
3) If O(n) retrieval is fast enough or if it is impractical to manipulate/maintain the data structure or an alternate, iterate over the List.
Before writing code more complex than a simple iteration over the List, it is worth thinking through some questions.
Why is something different needed? (Time) performance? Elegance? Maintainability? Reuse? All of these are okay reasons, apart or together, but they influence the solution.
How much control do you have over the data structure in question? Can you influence how it is built? Managed later?
What is the life cycle of the data structure (and underlying objects)? Is it built up all at once and never changed, or highly dynamic? Can your code monitor (or even alter) its life cycle?
Are there other important constraints, such as memory footprint? Does information about duplicates matter? Etc.
fenomas's answer was really good...it got me off of looking into the HTML code. I know that jb was looking for something that works in Captivate, but the question is broad enough to include people working out of Flash (I'm using CS5), so I thought I'd throw in the specific answer to my situation here.
If you're using the stock Adobe FLVPlayback component in Flash (you probably are if you used File > Import > Import Video...), there's an option in the Properties panel, under Component Parameters. Look for 'autoPlay' and uncheck it. That'll stop autoplay when the page loads!

String y = "hello";

As stated by David W. "First of all, check your URL" - Our dns entry changed breaking all svn repo connections. Connecting on ip instead of url as Wes stated worked - (now we have to fix our dns)
in your sample code you must remove the brackets, because it's not a functional assignment; also for documentary reasons I would suggest you use the :=
notation (see code sample below)
Application.Thisworkbook
refers to the book containing the VBA code, not necessarily the book containing the data, so be cautious.Express the sheet you're working on as a sheet object and pass it, together with a logical variable to the following sub:
Sub SetProtectionMode(MySheet As Worksheet, ProtectionMode As Boolean)
If ProtectionMode Then
MySheet.Protect DrawingObjects:=True, Contents:=True, _
AllowSorting:=True, AllowFiltering:=True
Else
MySheet.Unprotect
End If
End Sub
Within the .Protect
method you can define what you want to allow/disallow. This code block will switch protection on/off - without password in this example, you can add it as a parameter or hardcoded within the Sub. Anyway somewhere the PW will be hardcoded. If you don't want this, just call the Protection Dialog window and let the user decide what to do:
Application.Dialogs(xlDialogProtectDocument).Show
Hope that helps
Good luck - MikeD
None of the above worked for me today, so I tried putting the 0 in quotes, as shown in the example below.
Example: =IF(INDEX(a,b,c)="0","", INDEX(a,b,c))
One suspects this perennial bit of manager-candy was coined when everything was a sys app written in C because if nothing else the magic number would vary by orders of magnitude depending on the language, scale and nature of the application. And then you have to discount comments and attributes. And ultimately who cares about the number of lines of code written? Are you supposed to be finished when you've reach 10K lines? 100K? So arbitrary.
It's useless.
dict2 = dict1
does not copy the dictionary. It simply gives you the programmer a second way (dict2
) to refer to the same dictionary.

Unfortunately renewing does not seem to work in my case. My Ad Hoc Distribution Profile is about to expire in 5 days. I got warnings about that on the iPhone and the Xcode Organizer shows a warning sign next to it as well.
In Apple's provisioning portal it was marked as inactive and there was a button to reactivate it. But still with the same expiry date, 5 days from now. Next, I added two more iPhones to it, yet, the changed profile still expires 5 days from now.
Finally, I deleted the profile in the provisioning portal and created a new one from scratch, using a different name, yet this new one still expires on April 13th, 5 days from now!
That is really frustrating! So I guess I have to wait until after it expires and create a new one then.
In case you are wondering if my developer subscription runs out, it is not. I just renewed it in February.

Install mysysgit. (Same as Greg Hewgill's answer.)
Install Tortoisegit. (Tortoisegit requires mysysgit or something similiar like Cygwin.)
After TortoiseGit is installed, right-click on a folder, select Git Clone..., then enter the Url of the repository, then click Ok.
This answer is not any better than just installing mysysgit, but you can avoid the dreaded command line. :)
Be careful when setting text with an onClick listener on the field you are setting the text. I was doing this and setting the text to an empty string. This was causing the pointer to come up to indicate where my cursor was, which will normally go away after a few seconds. When I did not wait for it to go away before leaving my page causing finish() to be called, it would cause a memory leak and crash my app. Took me a while to figure out what was causing the crash on this one..
Anyway, I would recommend using selectAll() in your on click listener rather than setText() if you can. This way, once the text is selected, the user can start typing and all of the previous text will be cleared.

iOS 9 forces connections that are using HTTPS to be TLS 1.2 to avoid recent vulnerabilities. In iOS 8 even unencrypted HTTP connections were supported, so that older versions of TLS didn't make any problems either. As a workaround, you can add this code snippet to your Info.plist:
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
*referenced to App Transport Security (ATS)
Well, you can do
DataTable data = (DataTable)(dgvMyMembers.DataSource);
and then use
data.Columns.Remove(...);
I think it's the fastest way. This will modify data source table, if you don't want it, then copy of table is reqired. Also be aware that DataGridView.DataSource
is not necessarily of DataTable
type.
Starting with TypeScript 2.2 using dot notation to access indexed properties is allowed. You won't get error TS2339 on your example.
See Dotted property for types with string index signatures in TypeScript 2.2 release note.

Date convertedDate = new Date();
Date convertedDate2 = new Date();
try {
convertedDate = dateFormat.parse(date);
convertedDate2 = dateFormat.parse(dateafter);
if (convertedDate2.after(convertedDate)) {
txtView.setText("true");
} else {
txtView.setText("false");
}
} catch (ParseException e) {
// TODO Auto-generated catch block

it return true.. and you can also check before and equal with help of date.before and date.equal..
Yes. It is very simple to use String.replaceAll()
method:
package com.test;
public class Replace {
public static void main(String[] args) {
String input = "Hello World";
input = input.replaceAll("o", "0");
System.out.println(input);
}
}
Output:
Hell0 W0rld
If you really want to use StringBuilder.replace(int start, int end, String str)
instead then here you go:
public static void main(String args[]) {
StringBuilder sb = new StringBuilder("This is a new StringBuilder");
System.out.println("Before: " + sb);
String from = "new";
String to = "replaced";
sb = sb.replace(sb.indexOf(from), sb.indexOf(from) + from.length(), to);
System.out.println("After: " + sb);
}
Output:
Before: This is a new StringBuilder
After: This is a replaced StringBuilder
//To show xml tags in table columns you will have to encode the tags first

return $('<div/>').text(value).html();
}
html = htmlEncode(html)
I have experienced a great example of reproducing such a problem. Maybe my experience will help someone one day.
Check that your @Embedded Id of container has no possible collisions.
When Hibernate instantiates collection wrapper, it searches for already instantiated collection by CollectionKey in internal Map.
For Entity with @Embedded id, CollectionKey wraps EmbeddedComponentType and uses @Embedded Id properties for equality checks and hashCode calculation.
So if you have two entities with equal @Embedded Ids, Hibernate will instantiate and put new collection by the first key and will find same collection for the second key. So two entities with same @Embedded Id will be populated with same collection.
Suppose you have Account entity which has lazy set of loans. And Account has @Embedded Id consists of several parts(columns).
@Entity
@Table(schema = "SOME", name = "ACCOUNT")
public class Account {
@OneToMany(fetch = FetchType.LAZY, mappedBy = "account")
private Set<Loan> loans;
@Embedded
private AccountId accountId;
...
}
@Embeddable
public class AccountId {
@Column(name = "X")
private Long x;
@Column(name = "BRANCH")
private String branchId;
@Column(name = "Z")
private String z;
...
}
Then suppose that Account has additional property mapped by @Embedded Id but has relation to other entity Branch.
@ManyToOne(fetch = FetchType.EAGER)
@JoinColumn(name = "BRANCH")
@MapsId("accountId.branchId")
@NotFound(action = NotFoundAction.IGNORE)//Look at this!
private Branch branch;
It could happen that you have no FK for Account to Brunch relation id DB so Account.BRANCH column can have any value not presented in Branch table.
According to @NotFound(action = NotFoundAction.IGNORE)
if value is not present in related table, Hibernate will load null value for the property.
If X and Y columns of two Accounts are same(which is fine), but BRANCH is different and not presented in Branch table, hibernate will load null for both and Embedded Ids will be equal.
So two CollectionKey objects will be equal and will have same hashCode for different Accounts.
result = {CollectionKey@34809} "CollectionKey[Account.loans#Account@43deab74]"
role = "Account.loans"
key = {Account@26451}
keyType = {EmbeddedComponentType@21355}
factory = {SessionFactoryImpl@21356}
hashCode = 1187125168
entityMode = {EntityMode@17415} "pojo"
result = {CollectionKey@35653} "CollectionKey[Account.loans#Account@33470aa]"
role = "Account.loans"
key = {Account@35225}
keyType = {EmbeddedComponentType@21355}
factory = {SessionFactoryImpl@21356}
hashCode = 1187125168
entityMode = {EntityMode@17415} "pojo"
Because of this, Hibernate will load same PesistentSet for two entities.
Use the CSS3 Viewport-percentage feature.
Viewport-Percentage Explanation
Assuming you want the body width size to be a ratio of the browser's view port. I added a border so you can see the body resize as you change your browser width or height. I used a ratio of 90% of the view-port size.

(1) Set the tabindex
attribute:
<div id="mydiv" tabindex="0" />
(2) Bind to keydown:
$('#mydiv').on('keydown', function(event) {
//console.log(event.keyCode);
switch(event.keyCode){
//....your actions for the keys .....
}
});
To set the focus on start:
$(function() {
$('#mydiv').focus();
});
To remove - if you don't like it - the div
focus border, set outline: none
in the CSS.
See the table of keycodes for more keyCode
possibilities.
All of the code assuming you use jQuery.
#Try width:inherit
to make the image take the width of it's container <div>
. It will stretch/shrink it's height to maintain proportion. Don't set the height in the <div>
, it will size to fit the image height.
img {
width:inherit;
}
.item {
border:1px solid pink;
width: 120px;
float: left;
margin: 3px;
padding: 3px;
}
As a follow-up to the accepted answer, this is a minimal definition of the IHTMLScriptElement
interface which does not require to include additional type libraries:
[ComImport, ComVisible(true), Guid(@"3050f28b-98b5-11cf-bb82-00aa00bdce0b")]
[InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIDispatch)]
[TypeLibType(TypeLibTypeFlags.FDispatchable)]
public interface IHTMLScriptElement
{
[DispId(1006)]
string text { set; [return: MarshalAs(UnmanagedType.BStr)] get; }
}
So a full code inside a WebBrowser control derived class would look like:
protected override void OnDocumentCompleted(
WebBrowserDocumentCompletedEventArgs e)
{
base.OnDocumentCompleted(e);
// Disable text selection.
var doc = Document;
if (doc != null)
{
var heads = doc.GetElementsByTagName(@"head");
if (heads.Count > 0)
{
var scriptEl = doc.CreateElement(@"script");
if (scriptEl != null)
{
var element = (IHTMLScriptElement)scriptEl.DomElement;
element.text =
@"function disableSelection()
{
document.body.onselectstart=function(){ return false; };
document.body.ondragstart=function() { return false; };
}";
heads[0].AppendChild(scriptEl);
doc.InvokeScript(@"disableSelection");
}
}
}
}
You can iterate the key/value pairs of the saveData object to build an array of the pairs, then use join("&") on the resulting array:
var a = [];
for (key in saveData) {
a.push(key+"="+saveData[key]);
}
var serialized = a.join("&") // a=2&c=1
Since the name is likely to change in future versions of Android (currently the latest is AppCompatActivity
but it will probably change at some point), I believe a good thing to have is a class Activity
that extends AppCompatActivity
and then all your activities extend from that one. If tomorrow, they change the name to AppCompatActivity2
for instance you will have to change it just in one place.
Step by step:
In the new window you should see your connected phone.
I assume you are using the caption feature of Word, that is, captions were not typed in as normal text, but were inserted using Insert > Caption (Word versions before 2007), or References > Insert Caption (in the ribbon of Word 2007 and up). If done correctly, the captions are really 'fields'. You'll know if it is a field if the caption's background turns grey when you put your cursor on them (or is permanently displayed grey).
Captions are fields - Unfortunately fields (like caption fields) are only updated on specific actions, like opening of the document, printing, switching from print view to normal view, etc. The easiest way to force updating of all (caption) fields when you want it is by doing the following:
Captions are normal text - If the caption number is not a field, I am afraid you'll have to edit the text manually.

Unexpected end of file
means that something else was expected before the PHP parser reached the end of the script.
Judging from your HUGE file, it's probably that you're missing a closing brace (}
) from an if
statement.
Please at least attempt the following things:
;
in some of your embedded PHP statements, and not in others, ie. <?php echo base_url(); ?>
vs <?php echo $this->layouts->print_includes() ?>
. It's not required, so don't use it (or do, just do one or the other).There are cases when you want to restart a specific container instead of deleting the pod and letting Kubernetes recreate it.
Doing a kubectl exec POD_NAME -c CONTAINER_NAME /sbin/killall5
worked for me.
(I changed the command from reboot
to /sbin/killall5
based on the below recommendations.)
First the bigint(20) not null auto_increment
will not work, simply use bigserial primary key
. Then datetime
is timestamp
in PostgreSQL. All in all:
CREATE TABLE article (
article_id bigserial primary key,
article_name varchar(20) NOT NULL,
article_desc text NOT NULL,
date_added timestamp default NULL
);
When you use df.apply()
, each row of your DataFrame will be passed to your lambda function as a pandas Series. The frame's columns will then be the index of the series and you can access values using series[label]
.
So this should work:
df['D'] = (df.apply(lambda x: myfunc(x[colNames[0]], x[colNames[1]]), axis=1))
it is easy try to use this command :
ls | grep \.txt$ && ls | grep \.exe
Sub AddColor()
For Each cell In Selection
R = Round(cell.Value)
G = Round(cell.Offset(0, 1).Value)
B = Round(cell.Offset(0, 2).Value)
Cells(cell.Row, 1).Resize(1, 4).Interior.Color = RGB(R, G, B)
Next cell
End Sub
Assuming that there are 3 columns R, G and B (in this order). Select first column ie R. press alt+F11 and run the above code. We have to select the first column (containing R or red values) and run the code every time we change the values to reflect the changes.
I hope this simpler code helps !
have a look at the php documentation for theese functions you can send post reqeust using them.
fsockopen()
fputs()
or simply use a class like Zend_Http_Client which is also based on socket-conenctions.
also found a neat example using google...

lst2 = range(100)
lst3 = range(100)
percentile_list = pd.DataFrame(

If you need a more performant solution you can use np.column_stack
rather than zip
as in your first attempt, this has around a 2x speedup on the example here, however comes at bit of a cost of readability in my opinion:
import numpy as np
percentile_list = pd.DataFrame(np.column_stack([lst1, lst2, lst3]),
columns=['lst1Title', 'lst2Title', 'lst3Title'])
Another take on this problem in 2020 ... Here's a generalization of the problem. I interpret the 'divide a list in half' to be .. (i.e. two lists only and there shall be no spillover to a third array in case of an odd one out etc). For instance, if the array length is 19 and a division by two using // operator gives 9, and we will end up having two arrays of length 9 and one array (third) of length 1 (so in total three arrays). If we'd want a general solution to give two arrays all the time, I will assume that we are happy with resulting duo arrays that are not equal in length (one will be longer than the other). And that its assumed to be ok to have the order mixed (alternating in this case).
"""
arrayinput --> is an array of length N that you wish to split 2 times
"""
ctr = 1 # lets initialize a counter
holder_1 = []
holder_2 = []
for i in range(len(arrayinput)):
if ctr == 1 :
holder_1.append(arrayinput[i])
elif ctr == 2:
holder_2.append(arrayinput[i])
ctr += 1
if ctr > 2 : # if it exceeds 2 then we reset
ctr = 1
This concept works for any amount of list partition as you'd like (you'd have to tweak the code depending on how many list parts you want). And is rather straightforward to interpret. To speed things up , you can even write this loop in cython / C / C++ to speed things up. Then again, I've tried this code on relatively small lists ~ 10,000 rows and it finishes in a fraction of second.
Just my two cents.
Thanks!
Just use this constructor of List<T>
. It accepts any IEnumerable<T>
as an argument.
string[] arr = ...
List<string> list = new List<string>(arr);
You never need to set objects to null in C#. The compiler and runtime will take care of figuring out when they are no longer in scope.
Yes, you should dispose of objects that implement IDisposable.
I don't think the accepted answer works anymore. According to Microsoft here, here, and here, asp.net-5 has been re-branded to ASP.Net Core
. It looks like they've taken down the asp.net-5 templates from the general ASP.Net Web Application project type. But now there's a new project type of ASP.Net Core Web Application. I don't see an MVC template for this project type, but I don't think the Core framework has been completely released yet.
<script>
//$(document).ready(function () {
function showcontent() {
document.getElementById("demo22").innerHTML = "Hello World";
}
//});// end of ready function
</script>
I had the same problem where onclick function calls would not work. I had included the function inside the usual "$(document).ready(function(){});" block used to wrap jquery scripts. Commenting this block out solved the problem.
The finally block is always run after the try block ends, whether try ends normally or abnormally due to an exception, er, throwable.
If an exception is thrown by any of the code within the try block, then the current method simply re-throws (or continues to throw) the same exception (after running the finally block).
If the finally block throws an exception / error / throwable, and there is already a pending throwable, it gets ugly. Quite frankly, I forget exactly what happens (so much for my certification years ago). I think both throwables get linked together, but there is some special voodoo you have to do (i.e. - a method call I would have to look up) to get the original problem before the "finally" barfed, er, threw up.
Incidentally, try/finally is a pretty common thing to do for resource management, since java has no destructors.
E.g. -
r = new LeakyThing();
try { useResource( r); }
finally { r.release(); } // close, destroy, etc
"Finally", one more tip: if you do bother to put in a catch, either catch specific (expected) throwable subclasses, or just catch "Throwable", not "Exception", for a general catch-all error trap. Too many problems, such as reflection goofs, throw "Errors", rather than "Exceptions", and those will slip right by any "catch all" coded as:
catch ( Exception e) ... // doesn't really catch *all*, eh?
do this instead:
catch ( Throwable t) ...
Here is the method by using explode
:
$text = explode('_', '233718_This_is_a_string', 2)[1]; // Returns This_is_a_string
or:
$text = @end((explode('_', '233718_This_is_a_string', 2)));
By specifying 2
for the limit
parameter in explode()
, it returns array with 2 maximum elements separated by the string delimiter. Returning 2nd element ([1]
), will give the rest of string.
Here is another one-liner by using strpos
(as suggested by @flu):
$needle = '233718_This_is_a_string';
$text = substr($needle, (strpos($needle, '_') ?: -1) + 1); // Returns This_is_a_string
I meet the problem when using Firebase, i think different package cause the problem.
I solved by adding packeage of new app within Firebase Console, and download google-services.json again.
If embed no longer works for you, try with /v

I was facing a similar issue and found that a few fields like Date were not getting a concrete value, once given the values things worked fine. Please make sure you do not have date or any other field present on the form which needs a concrete value.
If you want to be general, you have to look at the precise specification of the a tag, like here. But even with that, if you do your perfect regexp, what if you have malformed html?
I would suggest to go for a library to parse html, depending on the language you work with: e.g. like python's Beautiful Soup.
In Jenkins ver. 1.635, it is impossible to show a native environment variable like this:
$BUILD_NUMBER or ${BUILD_NUMBER}
In this case, you have to set it in an other variable.
set BUILDNO = $BUILD_NUMBER
$BUILDNO
You were setting BCC but then overwriting the variable with the FROM
$to = "[email protected]";
$subject .= "".$emailSubject."";
$headers .= "Bcc: ".$emailList."\r\n";
$headers .= "From: [email protected]\r\n" .
"X-Mailer: php";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";
$message = '<html><body>';
$message .= 'THE MESSAGE FROM THE FORM';
if (mail($to, $subject, $message, $headers)) {
$sent = "Your email was sent!";
} else {
$sent = ("Error sending email.");
}
If you build packages from scratch:
Specifically, if you build bash
from source, install docs, including man pages, will fail (silently) without makeinfo
available.
The better option would be to just use the resource returned array as an array, meaning :
getResources().getStringArray(R.array.your_array)[position]
This is a shortcut approach of above mentioned approaches but does the work in the fashion you want. Otherwise android doesnt provides direct XML indexing for xml based arrays.
Here's a slightly less complicated answer:
NSString *myString = @"abcdefg";
NSString *mySmallerString = [myString substringToIndex:4];

All you need is:
guard let url = URL(string: "http://www.google.com") else {
return //be safe
}
if #available(iOS 10.0, *) {
UIApplication.shared.open(url, options: [:], completionHandler: nil)
} else {
UIApplication.shared.openURL(url)
}
To suppress output, use redirection to NUL
.
There are two kinds of output that console commands use:
standard output, or stdout
,
standard error, or stderr
.
Of the two, stdout
is used more often, both by internal commands, like copy
, and by console utilities, or external commands, like find
and others, as well as by third-party console programs.
>NUL
suppresses the standard output and works fine e.g. for suppressing the 1 file(s) copied.
message of the copy
command. An alternative syntax is 1>NUL
. So,
COPY file1 file2 >NUL
or
COPY file1 file2 1>NUL
or
>NUL COPY file1 file2
or
1>NUL COPY file1 file2
suppresses all of COPY
's standard output.
To suppress error messages, which are typically printed to stderr
, use 2>NUL
instead. So, to suppress a File Not Found
message that DEL
prints when, well, the specified file is not found, just add 2>NUL
either at the beginning or at the end of the command line:
DEL file 2>NUL
or
2>NUL DEL file
Although sometimes it may be a better idea to actually verify whether the file exists before trying to delete it, like you are doing in your own solution. Note, however, that you don't need to delete the files one by one, using a loop. You can use a single command to delete the lot:
IF EXIST "%scriptDirectory%*.noext" DEL "%scriptDirectory%*.noext"
You can change the port in the console by running the following on Windows:
SET PORT=8000
For Mac, Linux or Windows WSL use the following:
export PORT=8000
The export sets the environment variable for the current shell and all child processes like npm that might use it.
If you want the environment variable to be set just for the npm process, precede the command with the environment variable like this (on Mac and Linux and Windows WSL):
PORT=8000 npm run start
If you have a border or padding, then the solution
html, body {_x000D_
margin: 0;_x000D_
height: 100%;_x000D_
}_x000D_
body {_x000D_
border: solid red 5px;_x000D_
border-radius: 2em;_x000D_
}
_x000D_
produces the imperfect rendering
To get it right in the presence of a border or padding
use instead
html, body {_x000D_
margin: 0;_x000D_
height: 100%;_x000D_
}_x000D_
body {_x000D_
box-sizing: border-box;_x000D_
border: solid red 5px;_x000D_
border-radius: 2em;_x000D_
}
_x000D_
as Martin pointed out, although overflow: hidden
is not needed.

You need to provide a valid strict weak ordering comparison for the type stored in the queue, Person
in this case. The default is to use std::less<T>
, which resolves to something equivalent to operator<
. This relies on it's own stored type having one. So if you were to implement
bool operator<(const Person& lhs, const Person& rhs);
it should work without any further changes. The implementation could be
bool operator<(const Person& lhs, const Person& rhs)
{
return lhs.age < rhs.age;
}
If the the type does not have a natural "less than" comparison, it would make more sense to provide your own predicate, instead of the default std::less<Person>
. For example,
struct LessThanByAge
{
bool operator()(const Person& lhs, const Person& rhs) const
{
return lhs.age < rhs.age;
}
};
then instantiate the queue like this:
std::priority_queue<Person, std::vector<Person>, LessThanByAge> pq;
Concerning the use of std::greater<Person>
as comparator, this would use the equivalent of operator>
and have the effect of creating a queue with the priority inverted WRT the default case. It would require the presence of an operator>
that can operate on two Person
instances.
Use the Character.toString()
method like so:
char mChar = 'l';
String s = Character.toString(mChar);
This works
String x = "22/06/2012";
String y = "25/10/2014";
String datestart = x;
String datestop = y;
//DateTimeFormatter format = DateTimeFormat.forPattern("dd/mm/yyyy");
SimpleDateFormat format = new SimpleDateFormat("dd/mm/yyyy");
Date d1 = null;
Date d2 = null;
try {
d1 = format.parse(datestart);
d2 = format.parse(datestop);
DateTime dt1 = new DateTime(d1);
DateTime dt2 = new DateTime(d2);
//Period
period = new Period (dt1,dt2);
//calculate days
int days = Days.daysBetween(dt1, dt2).getDays();
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
you may forgot to wrap your object with $()
var tableChild = children[i];
tableChild.val("my Value");// this is wrong
and the ccorrect one is
$(tableChild).val("my Value");// this is correct
This issue arises because of different reasons. It might encountered if you are using Spring boot built war file. As Spring boot web and rest starter projects jars do have embedded Tomcat in it, hence fails with "SEVERE: ContainerBase.addChild: start: org.apache.catalina.LifecycleException".
You can fix this by exclusion of the embedded tomcat at the time of packaging by using exclusions in case of maven.
Maven dependency of "spring-boot-starter-web" will look like
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
</exclusion>
</exclusions>
</dependency>
This HTML is fine:
<a href="#" id="contactUs">Contact Us</a>
<div id="dialog" title="Contact form">
<p>appear now</p>
</div>
You need to initialize the Dialog (not sure if you are doing this):
$(function() {
// this initializes the dialog (and uses some common options that I do)
$("#dialog").dialog({
autoOpen : false, modal : true, show : "blind", hide : "blind"
});
// next add the onclick handler
$("#contactUs").click(function() {
$("#dialog").dialog("open");
return false;
});
});
Structure types should, whenever practical, either have all of their state encapsulated in public fields which may independently be set to any values which are valid for their respective type, or else behave as a single unified value which can only bet set via constructor, factory, method, or else by passing an instance of the struct as an explicit ref
parameter to one of its public methods. Contrary to what some people claim, that there's nothing wrong with a struct having public fields, if it is supposed to represent a set of values which may sensibly be either manipulated individually or passed around as a group (e.g. the coordinates of a point). Historically, there have been problems with structures that had public property setters, and a desire to avoid public fields (implying that setters should be used instead) has led some people to suggest that mutable structures should be avoided altogether, but fields do not have the problems that properties had. Indeed, an exposed-field struct is the ideal representation for a loose collection of independent variables, since it is just a loose collection of variables.
In your particular example, however, it appears that the two fields of your struct are probably not supposed to be independent. There are three ways your struct could sensibly be designed:
You could have the only public field be the string, and then have a read-only "helper" property called length
which would report its length if the string is non-null, or return zero if the string is null.
You could have the struct not expose any public fields, property setters, or mutating methods, and have the contents of the only field--a private string--be specified in the object's constructor. As above, length
would be a property that would report the length of the stored string.
You could have the struct not expose any public fields, property setters, or mutating methods, and have two private fields: one for the string and one for the length, both of which would be set in a constructor that takes a string, stores it, measures its length, and stores that. Determining the length of a string is sufficiently fast that it probably wouldn't be worthwhile to compute and cache it, but it might be useful to have a structure that combined a string and its GetHashCode
value.
It's important to be aware of a detail with regard to the third design, however: if non-threadsafe code causes one instance of the structure to be read while another thread is writing to it, that may cause the accidental creation of a struct instance whose field values are inconsistent. The resulting behaviors may be a little different from those that occur when classes are used in non-threadsafe fashion. Any code having anything to do with security must be careful not to assume that structure fields will be in a consistent state, since malicious code--even in a "full trust" enviroment--can easily generate structs whose state is inconsistent if that's what it wants to do.
PS -- If you wish to allow your structure to be initialized using an assignment from a string, I would suggest using an implicit conversion operator and making Length
be a read-only property that returns the length of the underlying string if non-null, or zero if the string is null.
I think I solved it removing the check mark to Break all processes when one process breaks
in Debug options (op's first screenshot->second option).
It's been building/running well for a while since I unchecked it.
I'm using MySql NET Connector and DevExpress controls in my project. May be one of them was not disposing connections, bindings, etc. well because of this flag beeing activated.
EDITED: definitely it works! No more 'Unable to copy file' and no more Form designer errors.
In my case, setting Copy to Output Directory
to Copy Always
and Build did not do the trick, while Rebuild did.
Hope this helps someone!
$product_id = $this->input->get('id', TRUE);

I have found the answer and solution to this problem. Before, I did not know that php.ini resides where in wordpress files. Now I have found that file in wp-admin directory where I placed the code
post_max_size 33M
upload_max_filesize 32M
then it worked. It increases the upload file size for my worpdress website. But, it is the same 2M as was before on cPanel.
If you're using bash
version > 4.0, you can exploit shopt -s globstar
to make short work of this:
shopt -s globstar; tar -czvf deploy.tar.gz **/Alice*.yml **/Bob*.json
this will add all .yml files that starts with Alice from any sub-directory and add all .json files that starts with Bob from any sub-directory.
Try this one, it worked for me in Athena:
cast(MyVarcharCol as integer)
These are utf-8 encoded characters. Use utf8_decode() to convert them to normal ISO-8859-1 characters.
Just use the function below that returns width and height of the screen size as an array of integers
private int[] getScreenSIze(){
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int h = displaymetrics.heightPixels;
int w = displaymetrics.widthPixels;
int[] size={w,h};
return size;
}
On your onCreate function or button click add the following code to output the screen sizes as shown below
int[] screenSize= getScreenSIze();
int width=screenSize[0];
int height=screenSize[1];
screenSizes.setText("Phone Screen sizes \n\n width = "+width+" \n Height = "+height);
In case you expect more than one maximum this will work:
_.maxBy(Object.entries(_.groupBy(x, y => y.length)), y => parseInt(y[0]))[1]
It uses lodash and returns an array.
Use npm run[-script] <script name>
After using npm to install the bin package to your local ./node_modules
directory, modify package.json
to add <script name>
like this:
$ npm install --save learnyounode
$ edit packages.json
>>> in packages.json
...
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"learnyounode": "learnyounode"
},
...
$ npm run learnyounode
It would be nice if npm install had a --add-script option or something or if npm run would work without adding to the scripts block.
I prefer to specify the table and the schema owner.
Watch out for case sensitivity as well. (see "upper" clause below).
I threw a couple of different objects in to show that is can be used in places besides TABLEs.
.............
declare
v_counter int;
begin
select count(*) into v_counter from dba_users where upper(username)=upper('UserSchema01');
if v_counter > 0 then
execute immediate 'DROP USER UserSchema01 CASCADE';
end if;
end;
/
CREATE USER UserSchema01 IDENTIFIED BY pa$$word
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp
QUOTA UNLIMITED ON users;
grant create session to UserSchema01;
And a TABLE example:
declare
v_counter int;
begin
select count(*) into v_counter from all_tables where upper(TABLE_NAME)=upper('ORDERS') and upper(OWNER)=upper('UserSchema01');
if v_counter > 0 then
execute immediate 'DROP TABLE UserSchema01.ORDERS';
end if;
end;

You can do that but the changes will affect for new data that is inserted on the database. On the long run follow as suggested above.
Also there are certain tricks you can override the collation, such as parameters for stored procedures or functions, alias data types, and variables are assigned the default collation of the database. To change the collation of an alias type, you must drop the alias and re-create it.
You can override the default collation of a literal string by using the COLLATE clause. If you do not specify a collation, the literal is assigned the database default collation. You can use DATABASEPROPERTYEX to find the current collation of the database.
You can override the server, database, or column collation by specifying a collation in the ORDER BY clause of a SELECT statement.
You can probably add two foreign key constraints (honestly: I've never tried it), but it'd then insist the parent row exist in both tables.
Instead you probably want to create a supertype for your two employee subtypes, and then point the foreign key there instead. (Assuming you have a good reason to split the two types of employees, of course).
employee
employees_ce ———————— employees_sn
———————————— type ————————————
empid —————————> empid <——————— empid
name /|\ name
|

deductions |

empid ————————+
name
type
in the employee table would be ce
or sn
.

Based on Vasily Sochinsky's answer a bit tweaked & with a small fix:
public static void unzip(File zipFile, File targetDirectory) throws IOException {
ZipInputStream zis = new ZipInputStream(
new BufferedInputStream(new FileInputStream(zipFile)));
try {
ZipEntry ze;
int count;
byte[] buffer = new byte[8192];
while ((ze = zis.getNextEntry()) != null) {
File file = new File(targetDirectory, ze.getName());
File dir = ze.isDirectory() ? file : file.getParentFile();
if (!dir.isDirectory() && !dir.mkdirs())
throw new FileNotFoundException("Failed to ensure directory: " +
dir.getAbsolutePath());
if (ze.isDirectory())
continue;
FileOutputStream fout = new FileOutputStream(file);
try {
while ((count = zis.read(buffer)) != -1)
fout.write(buffer, 0, count);
} finally {
fout.close();
}
/* if time should be restored as well
long time = ze.getTime();
if (time > 0)

*/
}
} finally {
zis.close();
}
}
Notable differences
public static
- this is a static utility method that can be anywhere.File
parameters because String
are :/ for files and one could not specify where the zip file is to be extracted before. Also path + filename
concatenation > https://stackoverflow.com/a/412495/995891throws
- because catch late - add a try catch if really not interested in them.mkdirs()
is important.finally
to prevent resource leaks.So
unzip(new File("/sdcard/pictures.zip"), new File("/sdcard"));
should do the equivalent of the original
unpackZip("/sdcard/", "pictures.zip")
For Fiddler to capture traffic from localhost on local IIS, there are 3 steps (It worked on my computer):
node-http-proxy is a great solution as was suggested by @hross above. If you're not deadset on using node, we use NGINX to do the same thing. It works really well with node. We use it for example to process SSL requests before forwarding them to node. It can also handle cacheing and forwarding routes. Yay!
using(StreamWriter writer = new StreamWriter("debug.txt", true))
{
writer.WriteLine("whatever you text is");
}
The second "true" parameter tells it to append.
Technically, I have seen HTTP GET will have issues if the URL length goes beyond 2000 characters. In that case, it's better to use HTTP POST or split the URL.
Use the Make shell

you can use optional variable by ?

To follow up on Yenchi's comment above, the OK button will also do nothing if the camera app can't write to the directory in question.
That means that you can't create the file in a place that's only writeable by your application (for instance, something under getCacheDir())
Something under getExternalFilesDir()
ought to work, however.
It would be nice if the camera app printed an error message to the logs if it could not write to the specified EXTRA_OUTPUT
path, but I didn't find one.
You can learn commands from the command palette Ctrl/Cmd + Shift + P). Look for "Go to Bracket". The keybinding is also shown there.
Would it be as easy as running a LINQ query on your List?
List<string> mylist = new List<string>{ "hello","world","foo","bar"};
List<string> listContainingLetterO = mylist.Where(x=>x.Contains("o")).ToList();
Although that question is pretty old, I came here via google and I found a quite simple way: List slicing. Let's say you want to put an '&' between all list entries.
s = ""
l = [1, 2, 3]
for i in l[:-1]:
s = s + str(i) + ' & '
s = s + str(l[-1])
This returns '1 & 2 & 3'.
The following command has served me well in finding date/time metadata on various AVI/MP4 videos:
ffmpeg -i /path/to/video.mp4 -dump
Note: as mentioned in other answers, there is no guarantee that such information is available in all video files or available in a specific format.

Lot of good answers, here is another way to clean up a string of numbers, is not deleting chars but by moving the numbers out.
string str("(555) 555-5555"), clean;
for (char c : str)
if (c >= 48 and c <= 57)
clean.push_back(c);
The sequel gem adds an update_or_create method which seems to do what you're looking for.
As I can see, you are comparing the message with the empty string using ==.
Its very hard to write the full code, but I can tell the flow of code - first, create db class & method inide that which will return the connection. second, create a servelet(ex-login.java) & import that db class onto that servlet. third, create instance of imported db class with the help of new operator & call the connection method of that db class. fourth, creaet prepared statement & execute statement & put this code in try catch block for exception handling.Use if-else condition in the try block to navigate your login page based on success or failure.
I hope, it will help you. If any problem, then please revert.

Readability can be improved by static factory methods:
Compare
public class Foo{
public Foo(boolean withBar){
//...
}
}
//...
// What exactly does this mean?
Foo foo = new Foo(true);
// You have to lookup the documentation to be sure.
// Even if you remember that the boolean has something to do with a Bar
// you might not remember whether it specified withBar or withoutBar.
to
public class Foo{
public static Foo createWithBar(){
//...
}
public static Foo createWithoutBar(){
//...
}
}
// ...
// This is much easier to read!
Foo foo = Foo.createWithBar();
Take a look at JSMPEG project. There is a great idea implemented there — to decode MPEG in the browser using JavaScript. Bytes from encoder (FFMPEG, for example) can be transfered to browser using WebSockets or Flash, for example. If community will catch up, I think, it will be the best HTML5 live video streaming solution for now.
put your CA & root certificate in /usr/share/ca-certificate or /usr/local/share/ca-certificate. Then
dpkg-reconfigure ca-certificates
or even reinstall ca-certificate package with apt-get.
After doing this your certificate is collected into system's DB: /etc/ssl/certs/ca-certificates.crt
Then everything should be fine.
If you know which operating systems your application will be running on, I would create one virtualenv for each system and include it in my repository. Then I would make my application detect which system it is running on and use the corresponding virtualenv.
The system could e.g. be identified using the platform module.
In fact, this is what I do with an in-house application I have written, and to which I can quickly add a new system's virtualenv in case it is needed. This way, I do not have to rely on that pip will be able to successfully download the software my application requires. I will also not have to worry about compilation of e.g. psycopg2 which I use.
If you do not know which operating system your application may run on, you are probably better off using pip freeze
as suggested in other answers here.
Try This query:

Be careful using SelectedItem.Text... If there is no item selected, then SelectedItem will be null and SelectedItem.Text will generate a null-value exception.
.NET should have provided a SelectedText property like the SelectedValue property that returns String.Empty when there is no selected item.
I had to get clean table without columns. I have done folowing:
jMyTable.setModel(new DefaultTableModel());
Set the Format to Custom and then specify the format:
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "MM/dd/yyyy hh:mm:ss";
or however you want to lay it out. You could then type in directly the date/time. If you use MMM, you'll need to use the numeric value for the month for entry, unless you write some code yourself for that (e.g., 5 results in May)
Don't know about the picker for date and time together. Sounds like a custom control to me.
Thing's to be Consider While Designing the Elevator System,
Elevator
Floor/Location Identifier
Number of steps
Rotation speed
Daterange
InstallationDate
MaintainenceDate
Department Identifier
AllowedWeight
Detail / Description
Poison Ratio (Statistics)
Start
Stop
SetDirection

Each button press results in an elevator request which has to be served. Each of these requests is tracked at a global place
The number of elevators in the building will be determined by the user. The building will contain a fixed number of floors. The number of passengers that can fit into the elevator will be fixed. The passengers will be counted as they leave the elevator at their destination floor. The destination floor will be determined using a "random" Poisson interval. When all of the passengers in the elevator have reached their destination floors, the elevator will return to the lobby to pickup more passengers
To add new ViewController
once you have have an existing ViewController
, follow below step:
Click on background of Main.storyboard
.
Search and select ViewController
from object library at the
utility window.
Drag and drop it in background to create a new ViewController
.
You have several options:
.gitignore
file in your working dir (or apply it automatically using topgit or some other such patch tool).$GIT_DIR/info/exclude
file, if this is specific to one tree.git config --global core.excludesfile ~/.gitignore
and add patterns to your ~/.gitignore
. This option applies if you want to ignore certain patterns across all trees. I use this for .pyc
and .pyo
files, for example.Also, make sure you are using patterns and not explicitly enumerating files, when applicable.
Short answer: Not likely.
Long answer: Your compiler has an optimizer in it that knows how to multiply as quickly as your target processor architecture is capable. Your best bet is to tell the compiler your intent clearly (i.e. i*2 rather than i << 1) and let it decide what the fastest assembly/machine code sequence is. It's even possible that the processor itself has implemented the multiply instruction as a sequence of shifts & adds in microcode.
Bottom line--don't spend a lot of time worrying about this. If you mean to shift, shift. If you mean to multiply, multiply. Do what is semantically clearest--your coworkers will thank you later. Or, more likely, curse you later if you do otherwise.
I think this first failed because you are ordering value which is null. If Delivery is a foreign key associated table then you should include this table first, example below:
var itemList = from t in ctn.Items.Include(x=>x.Delivery)
where !t.Items && t.DeliverySelection
orderby t.Delivery.SubmissionDate descending
select t;
You don't need those imports. The only thing you need in your urls.py (to start) is:
from django.conf.urls.defaults import *
# This two if you want to enable the Django Admin: (recommended)
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
# ... your url patterns
)
NOTE: This solution was intended for Django <1.6. This was actually the code generated by Django itself. For newer version, see Jacob Hume's answer.
You could use memset, if you sure about the length.
memset(ptr, 0x00, length)
When it comes to areal device, the behavior of devices seem different to a different group of devices.
Some of the strange collection of the opinion I heard form different people is:
./adb install ~Application_path
android:installLocation="preferExternal"
I hope one of them is relevant to you! ;)
You can also do like this if you're only interested in extracting the "user_id":
String userId =
given().
contentType("application/json").
body(requestBody).
when().
post("/admin").
then().
statusCode(200).
extract().
path("user_id");
In its simplest form it looks like this:
String userId = get("/person").path("person.userId");
mail -s "Your Subject" [email protected] < /file/with/mail/content
(/file/with/mail/content
should be a plaintext file, not a file attachment or an image, etc)
use a blackslash not a forwardslash. \n
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="title">Hello\nWorld!</string>
</resources>
Also, if you plan on using the string as HTML, you can use <br />
for a line break(<br />
)
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="title">Hello<br />World!</string>
</resources>
Use this with WPF:
Cursor = Cursors.Wait;
// Your Heavy work here
Cursor = Cursors.Arrow;
Some answers are slightly incorrect and point to the wrong part of the docs:
If you want a component to render nothing, just return null
, as per doc:
In rare cases you might want a component to hide itself even though it was rendered by another component. To do this return null instead of its render output.
If you try to return undefined
for example, you'll get the following error:
Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null.
As pointed out by other answers, null
, true
, false
and undefined
are valid children which is useful for conditional rendering inside your jsx, but it you want your component to hide / render nothing, just return null
.
HTML and XML entities are just a way of referencing a Unicode code-point in a way that reliably works regardless of the encoding of the actual page, making them useful for using esoteric Unicode characters in a page using 7-bit ASCII or some other encoding scheme, ideally on a one-off basis. They're also used to escape the <
, >
, "
and &
characters as these are reserved in SGML.
Anyway, Unicode has a number of tick/check characters, as per Wikipedia ( http://en.wikipedia.org/wiki/Tick_(check_mark) ).
Ideally you should save/store your HTML in a Unicode format like UTF-8 or 16, thus obviating the need to use HTML entities to represent a Unicode character. Nonetheless use: ✔
✔.
✔
✔
Is using hex notation and is the same as
$#10004;
(as 2714
in base 16 is the same as 10004
in base 10)
Check if you also installed the "Google Repository". If not, you also have to install the "Google Repository" in your SDK Manager.
Also be aware that there might be 2 SDK installations - one coming from AndroidStudio and one you might have installed. Better consolidate this to one installation - this is a common pitfall - that you have it installed in one installation but it fails when you build with the other installation.
Peer dependency warnings, more often than not, can be ignored. The only time you will want to take action is if the peer dependency is missing entirely, or if the version of a peer dependency is higher than the version you have installed.
Let's take this warning as an example:
npm WARN @angular/[email protected] requires a peer of @angular/[email protected] but none is installed. You must install peer dependencies yourself.
With Angular, you would like the versions you are using to be consistent across all packages. If there are any incompatible versions, change the versions in your package.json, and run npm install
so they are all synced up. I tend to keep my versions for Angular at the latest version, but you will need to make sure your versions are consistent for whatever version of Angular you require (which may not be the most recent).
In a situation like this:
npm WARN [email protected] requires a peer of @angular/core@^2.4.0 || ^4.0.0 but none is installed. You must install peer dependencies yourself.
If you are working with a version of Angular that is higher than 4.0.0, then you will likely have no issues. Nothing to do about this one then. If you are using an Angular version under 2.4.0, then you need to bring your version up. Update the package.json, and run npm install
, or run npm install
for the specific version you need. Like this:
npm install @angular/[email protected] --save
You can leave out the --save
if you are running npm 5.0.0 or higher, that version saves the package in the dependencies section of the package.json automatically.
In this situation:
npm WARN optional SKIPPING OPTIONAL DEPENDENCY: [email protected] (node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"})
You are running Windows, and fsevent requires OSX. This warning can be ignored.
Hope this helps, and have fun learning Angular!
For what it's worth, my groovy spike seems to work with both UTF-8 and ISO-8859-1 character encodings. Not sure what will happen when a non zxing decoder tries to decode the UTF-8 encoded image though... probably varies depending on the device.

You can use a free third party solution to handle this for you such as Quantum-Key.Net It's free and handles payments via paypal through a web sales page it creates for you, key issuing via email and locks key use to a specific computer to prevent piracy.
Your should also take care to obfuscate/encrypt your code or it can easily be reverse engineered using software such as De4dot and .NetReflector. A good free code obfuscator is ConfuserEx wich is fast and simple to use and more effective than expensive alternatives.
You should run your finished software through De4Dot and .NetReflector to reverse-engineer it and see what a cracker would see if they did the same thing and to make sure you have not left any important code exposed or undisguised.
Your software will still be crackable but for the casual cracker it may well be enough to put them off and these simple steps will also prevent your code being extracted and re-used.

Extending off of Rapti's answer, this should work just as well, but it adds more margin to the right side of the body
and hides it with negative html
margin, instead of adding extra padding that could potentially affect the page's layout. This way, nothing is changed on the actual page (in most cases), and the code is still functional.
html {
margin-right: calc(100% - 100vw);
}
body {
margin-right: calc(100vw - 100%);
}
Scott Murray wrote a great explanation of this[1]. For instance, for the code snippet:
svg.append("g")
.attr("class", "axis")
.attr("transform", "translate(0," + h + ")")
.call(xAxis);
He explains using the following:
Note that we use attr() to apply transform as an attribute of g. SVG transforms are quite powerful, and can accept several different kinds of transform definitions, including scales and rotations. But we are keeping it simple here with only a translation transform, which simply pushes the whole g group over and down by some amount.
Translation transforms are specified with the easy syntax of translate(x,y), where x and y are, obviously, the number of horizontal and vertical pixels by which to translate the element.

The accepted answer:
const initialState = {
/* etc */
};
class MyComponent extends Component {
constructor(props) {
super(props)
this.state = initialState;
}
reset() {
this.setState(initialState);
}
/* etc */
}
unfortunately is not correct.
initialState
is passed as a reference to this.state
, so whenever you change state
you also change initialState
(const doesn't really matter here). The result is that you can never go back to initialState
.
You have to deep copy initialState
to state
, then it will work. Either write a deep copy function yourself or use some existing module like this.
int
variables can't be null
If a null
is to be converted to int
, then it is the converter which decides whether to set 0
, throw exception, or set another value (like Integer.MIN_VALUE
). Try to plug your own converter.
After the merge, it's safe to delete the branch:
git branch -d branch1
Additionally, git will warn you (and refuse to delete the branch) if it thinks you didn't fully merge it yet. If you forcefully delete a branch (with git branch -D
) which is not completely merged yet, you have to do some tricks to get the unmerged commits back though (see below).
There are some reasons to keep a branch around though. For example, if it's a feature branch, you may want to be able to do bugfixes on that feature still inside that branch.
If you also want to delete the branch on a remote host, you can do:
git push origin :branch1
This will forcefully delete the branch on the remote (this will not affect already checked-out repositiories though and won't prevent anyone with push access to re-push/create it).
git reflog
shows the recently checked out revisions. Any branch you've had checked out in the recent repository history will also show up there. Aside from that, git fsck
will be the tool of choice at any case of commit-loss in git.

I don't expose any endpoints and start (with nohup in background and without out files created through nohup) and stop with shell script(with KILL PID gracefully and force kill if app is still running after 3 mins). I just create executable jar and use PID file writer to write PID file and store Jar and Pid in folder with same name as of application name and shell scripts also have same name with start and stop in the end. I call these stop script and start script via jenkins pipeline also. No issues so far. Perfectly working for 8 applications(Very generic scripts and easy to apply for any app).

In Kotlin it will look like this:
