Jersey 2.26 and newer are not backward compatible with older versions. The reason behind that has been stated in the release notes:
Unfortunately, there was a need to make backwards incompatible changes in 2.26. Concretely jersey-proprietary reactive client API is completely gone and cannot be supported any longer - it conflicts with what was introduced in JAX-RS 2.1 (that's the price for Jersey being "spec playground..").
Another bigger change in Jersey code is attempt to make Jersey core independent of any specific injection framework. As you might now, Jersey 2.x is (was!) pretty tightly dependent on HK2, which sometimes causes issues (esp. when running on other injection containers. Jersey now defines it's own injection facade, which, when implemented properly, replaces all internal Jersey injection.
As for now one should use the following dependencies:
Maven
<dependency>
<groupId>org.glassfish.jersey.inject</groupId>
<artifactId>jersey-hk2</artifactId>
<version>2.26</version>
</dependency>
Gradle
compile 'org.glassfish.jersey.core:jersey-common:2.26'
compile 'org.glassfish.jersey.inject:jersey-hk2:2.26'

I created an arrayList from it and I somehow can't find a way to store this information into a JTable.
The DefaultTableModel doesn't support displaying custom Objects stored in an ArrayList. You need to create a custom TableModel.
You can check out the Bean Table Model. It is a reusable class that will use reflection to find all the data in your FootballClub class and display in a JTable.
Or, you can extend the Row Table Model
found in the above link to make is easier to create your own custom TableModel by implementing a few methods. The JButtomTableModel.java
source code give a complete example of how you can do this.
I had same problem. After one day, I got it.
Problem was from adding two smtp
tags in mailSettings
under <system.net>
.
I've found this issue to be prevalent in Entity Framework when we instantiate an Entity manually rather than through DBContext which will resolve all the Navigation Properties. If there are Foreign Key references (Navigation Properties) between tables and you use those references in your lambda (e.g. ProductDetail.Products.ID) then that "Products" context remains null if you manually created the Entity.
I had this exact same problem in VS 2015
. It looks like as of VS 2010
and later you need to include #include "stdafx.h"
in all your projects.
#include "stdafx.h"
#include <iostream>
using namespace std;
The above worked for me. The below did not:
#include <iostream>
using namespace std;
This also failed:
#include <iostream>
using namespace std;
#include "stdafx.h"
Using jquery's map
function
var checkboxValues = [];
$('input[name=checkboxName]:checked').map(function() {
checkboxValues.push($(this).val());
});
I really wanted a pure css
solution to this myself, since sprinkling a weighty javascript solution around all of my views seemed like an unpleasant option. Finally found the @media.hover query, which can detect "whether the primary input mechanism allows the user to hover over elements." This avoids touch devices where "hovering" is more of an emulated action than a direct capability of the input device.
So for example, if I have a link:
<a href="/" class="link">Home</a>
Then I can safely style it to only :hover
when the device easily supports it with this css
:
@media (hover: hover) {
.link:hover { /* hover styles */ }
}
While most modern browsers support interaction media feature queries, some popular browsers such as IE and Firefox do not. In my case this works fine, since I only intended to support Chrome on desktop and Chrome and Safari on mobile.
As others have responded, the key you are trying to parse doesn't have the proper PKCS#8 headers which Oracle's PKCS8EncodedKeySpec
needs to understand it. If you don't want to convert the key using openssl pkcs8
or parse it using JDK internal APIs you can prepend the PKCS#8 header like this:
static final Base64.Decoder DECODER = Base64.getMimeDecoder();
private static byte[] buildPKCS8Key(File privateKey) throws IOException {
final String s = new String(Files.readAllBytes(privateKey.toPath()));
if (s.contains("--BEGIN PRIVATE KEY--")) {
return DECODER.decode(s.replaceAll("-----\\w+ PRIVATE KEY-----", ""));
}
if (!s.contains("--BEGIN RSA PRIVATE KEY--")) {
throw new RuntimeException("Invalid cert format: "+ s);
}
final byte[] innerKey = DECODER.decode(s.replaceAll("-----\\w+ RSA PRIVATE KEY-----", ""));
final byte[] result = new byte[innerKey.length + 26];
System.arraycopy(DECODER.decode("MIIEvAIBADANBgkqhkiG9w0BAQEFAASCBKY="), 0, result, 0, 26);
System.arraycopy(BigInteger.valueOf(result.length - 4).toByteArray(), 0, result, 2, 2);
System.arraycopy(BigInteger.valueOf(innerKey.length).toByteArray(), 0, result, 24, 2);
System.arraycopy(innerKey, 0, result, 26, innerKey.length);
return result;
}
Once that method is in place you can feed it's output to the PKCS8EncodedKeySpec
constructor like this: new PKCS8EncodedKeySpec(buildPKCS8Key(privateKey));
So the problem must be with your JCE Unlimited Strength installation.
Be sure you overwrite the local_policy.jar
and US_export_policy.jar
in both your JDK's jdk1.6.0_25\jre\lib\security\
and in your JRE's lib\security\
folder.
In my case I would place the new .jars in:
C:\Program Files\Java\jdk1.6.0_25\jre\lib\security
and
C:\Program Files\Java\jre6\lib\security
If you are running Java 8 and you encounter this issue. Below steps should help!
Go to your JRE installation (e.g - jre1.8.0_181\lib\security\policy\unlimited) copy local_policy.jar and replace it with 'local_policy.jar' in your JDK installation directory (e.g - jdk1.8.0_141\jre\lib\security).
Finally, it turned out to be a missing artifact of solr that seemed to block all the rest of my build cycle.
I have no idea why mvn behaves like that, but upgrading to the latest version fixed it.
See for a comparison of net-ioc-frameworks on google code including linfu and spring.net that are not on your list while i write this text.
I worked with spring.net: It has many features (aop, libraries , docu, ...) and there is a lot of experience with it in the dotnet and the java-world. The features are modularized so you donot have to take all features. The features are abstractions of common issues like databaseabstraction, loggingabstraction. however it is difficuilt to do and debug the IoC-configuration.
From what i have read so far: If i had to chooseh for a small or medium project i would use ninject since ioc-configuration is done and debuggable in c#. But i havent worked with it yet. for large modular system i would stay with spring.net because of abstraction-libraries.

Your command for creating the BKS keystore looks correct for me.
How do you initialize the keystore.
You need to craeate and pass your own SSLSocketFactory. Here is an example which uses Apache's org.apache.http.conn.ssl.SSLSocketFactory
But I think you can do pretty the same on the javax.net.ssl.SSLSocketFactory
private SSLSocketFactory newSslSocketFactory() {
try {
// Get an instance of the Bouncy Castle KeyStore format
KeyStore trusted = KeyStore.getInstance("BKS");
// Get the raw resource, which contains the keystore with
// your trusted certificates (root and any intermediate certs)
InputStream in = context.getResources().openRawResource(R.raw.mykeystore);
try {
// Initialize the keystore with the provided trusted certificates
// Also provide the password of the keystore
trusted.load(in, "testtest".toCharArray());
} finally {
in.close();
}
// Pass the keystore to the SSLSocketFactory. The factory is responsible
// for the verification of the server certificate.
SSLSocketFactory sf = new SSLSocketFactory(trusted);
// Hostname verification from certificate
// http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html#d4e506
sf.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);
return sf;
} catch (Exception e) {
throw new AssertionError(e);
}
}
Please let me know if it worked.
There is code and binaries available here for a console app that can export private keys marked as non-exportable, and it won't trigger antivirus apps like mimikatz will.
The code is based on a paper by the NCC Group.
will need to run the tool with the local system account, as it works by writing directly to memory used by Windows' lsass
process, in order to temporarily mark keys as exportable. This can be done using PsExec
from SysInternals' PsTools:
PsExec64.exe -s -i cmd
exportrsa.exe
For those who are using web servers make sure that the bcprov-jdk16-145.jar has been installed in you servers lib, for weblogic had to put the jar in:
<weblogic_jdk_home>\jre\lib\ext
return new String(Hex.encode(digest));
If you're getting this when trying to bind JAR files for a Xamarin.Android bindings project like so:
JARTOXML : warning J2XA006: missing class error was raised while reflecting com.your.class : Invalid signature file digest for Manifest main attributes
Just open the JAR files using Winzip and delete the meta-inf directories. Rebuild - job done
jsCH has worked great for me. Below is an example of a method that will connect to sftp server and download files to specified directory. It is recommended to stay away from disabling StrictHostKeyChecking. Although a little bit more difficult to set up, for security reasons specifying the known hosts should be the norm.
jsch.setKnownHosts("C:\Users\test\known_hosts"); recommended
JSch.setConfig("StrictHostKeyChecking", "no"); - not recommended
import com.jcraft.jsch.*;
public void downloadFtp(String userName, String password, String host, int port, String path) {
Session session = null;
Channel channel = null;
try {
JSch ssh = new JSch();
JSch.setConfig("StrictHostKeyChecking", "no");
session = ssh.getSession(userName, host, port);
session.setPassword(password);
session.connect();
channel = session.openChannel("sftp");
channel.connect();
ChannelSftp sftp = (ChannelSftp) channel;
sftp.get(path, "specify path to where you want the files to be output");
} catch (JSchException e) {
System.out.println(userName);
e.printStackTrace();
} catch (SftpException e) {
System.out.println(userName);
e.printStackTrace();
} finally {
if (channel != null) {
channel.disconnect();
}
if (session != null) {
session.disconnect();
}
}
}
Version=1.0.3.0 indicates Castle RC3, however the fluent interface was developed some months after the release of RC3. Therefore, it looks like you have a versioning problem. Maybe you have Castle RC3 registered in the GAC and it's using that one...
I've done a lot of work on this kind of parsing. Because there are errors you won't get 100% accuracy, but there are a few things you can do to get most of the way there, and then do a visual BS test. Here's the general way to go about it. It's not code, because it's pretty academic to write it, there's no weirdness, just lots of string handling.
(Now that you've posted some sample data, I've made some minor changes)
I hope this helps somewhat.
Try: if(parseInt(order)>0){....
One of the simplest ways to do this is like this
var totalWords = "my name is rahul.";_x000D_
var firstWord = totalWords.replace(/ .*/, '');_x000D_
alert(firstWord);_x000D_
console.log(firstWord);
_x000D_

It is late answer but can be useful for others. In view use ViewBag as following:
@Html.Raw("<script>" + ViewBag.DynamicScripts + "</script>")
Then from controller set this ViewBag as follows:
ViewBag.DynamicScripts = "javascriptFun()";
This will execute JavaScript function. But this function would not execute if it is ajax call. To call JavaScript function from ajax call back, return two values from controller and write success function in ajax callback as following:
$.ajax({
type: "POST",
url: "/Controller/Action", // the URL of the controller action method
data: null, // optional data
success: function(result) {
// do something with result
},
success: function(result, para) {
if(para == 'something'){
//run JavaScript function
}
},
error : function(req, status, error) {
// do something with error
}
});
from controller you can return two values as following:
return Json(new { json = jr.Data, value2 = "value2" });
Try storing the state in a attribute on the element itself, such as superDirectiveStatus="true"
For example:
angular.module('app')
.directive('superDirective', function ($compile, $injector) {
return {
restrict: 'A',
replace: true,
link: function compile(scope, element, attrs) {
if (element.attr('datepicker')) { // check
return;
}
var status = element.attr('superDirectiveStatus');
if( status !== "true" ){
element.attr('datepicker', 'someValue');
element.attr('datepicker-language', 'en');
// some more
element.attr('superDirectiveStatus','true');
$compile(element)(scope);
}
}
};
});
I hope this helps you.

You need to specify the column in both expressions.

To print to any printer on the network you can send a PJL/PCL print job directly to a network printer on port 9100.
Please have a look at the below link that should give a good start:
http://frank.zinepal.com/printing-directly-to-a-network-printer
Also, If there is a way to call Windows cmd you can use FTP put to print your page on 9100. Below link should give you details, I have used this method for HP printers but I believe it will work for other printers.

IF they are both UTC date-time values you can do TimeSpan diff = dateTime1 - dateTime2;
Otherwise your chance of getting the correct answer in every single possible case is zero.
No.
A workaround is to overload with another method that doesn't have out / ref parameters, and which just calls your current method.
public bool SomeMethod(out string input)
{
...
}
// new overload
public bool SomeMethod()
{
string temp;
return SomeMethod(out temp);
}
If you have C# 7.0, you can simplify:
// new overload
public bool SomeMethod()
{
return SomeMethod(out _); // declare out as an inline discard variable
}
(Thanks @Oskar / @Reiner for pointing this out.)
You can use
cat file.txt | xargs -i sh -c 'command {} | command2 {} && command3 {}'
{} = variable for each line on the text file
If you have the option pre-existing in a fixed-with <select>

title
attribute to each option. This is non-standard HTML (if you care for this minor infraction here), but IE (and Firefox as well) will display the entire text in a mouse popup on mouse hover.If you are adding a long option later through JavaScript, look here: How to update HTML “select” box dynamically in IE
SQL*Plus uses &1, &2... &n to access the parameters.
Suppose you have the following script test.sql
:
SET SERVEROUTPUT ON
SPOOL test.log
EXEC dbms_output.put_line('&1 &2');
SPOOL off
you could call this script like this for example:
$ sqlplus login/pw @test Hello World!
In a UNIX script you would usually call a SQL script like this:
sqlplus /nolog << EOF
connect user/password@db
@test.sql Hello World!
exit
EOF
so that your login/password won't be visible with another session's ps
As I got this case at my own and the answers here didn't help me, my situation was because of I downgraded the targetSdkVersion
in gradle app module file from 24 to 22 for some reason, and apparently the apk doesn't accept another one with downgraded targetSdkVersion
to be installed over it.
So, once I changed it back to 24 the error disappeared and app installed correctly.
File -> New Window
In the new window**
Run -> Python Shell
The problem with this method is that it will clear all the things you defined, such as variables.
Alternatively, you should just use command prompt.
open up command prompt
type "cd c:\python27"
type "python example.py" , you have to edit this using IDLE when it's not in interactive mode. If you're in python shell, file -> new window.
Note that the example.py needs to be in the same directory as C:\python27, or whatever directory you have python installed.
Then from here, you just press the UP arrow key on your keyboard. You just edit example.py, use CTRL + S, then go back to command prompt, press the UP arrow key, hit enter.
If the command prompt gets too crowded, just type "clr"
The "clr" command only works with command prompt, it will not work with IDLE.
I prefer to use windowed functions(MySQL 8.0+) to find duplicates because I could see entire row:
WITH cte AS (
SELECT *
,COUNT(*) OVER(PARTITION BY col_name) AS num_of_duplicates_group
,ROW_NUMBER() OVER(PARTITION BY col_name ORDER BY col_name2) AS pos_in_group
FROM table
)
SELECT *
FROM cte
WHERE num_of_duplicates_group > 1;
Currently, the link dlptest is working fine.
The files will only be stored for 30 minutes before being deleted.
Usually I will just use the undocumented proc sp_MSForEachTable

EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL'

Did you maybe use some <tab>
instead of spaces?
Try remove all the spaces before the code and readd them using <space>
characters, just to be sure it's not a <tab>

Using a form in a view pretty much explains it.
The standard pattern for processing a form in a view looks like this:
def contact(request):
if request.method == 'POST': # If the form has been submitted...
form = ContactForm(request.POST) # A form bound to the POST data
if form.is_valid(): # All validation rules pass
# Process the data in form.cleaned_data
# ...
print form.cleaned_data['my_form_field_name']
return HttpResponseRedirect('/thanks/') # Redirect after POST
else:
form = ContactForm() # An unbound form
return render_to_response('contact.html', {
'form': form,
})
If the browser that you are planning to use is Mozilla (Addon development) (not sure of chrome) you can use the following method in Javascript
function DOM( string )
{
var {Cc, Ci} = require("chrome");
var parser = Cc["@mozilla.org/xmlextras/domparser;1"].createInstance(Ci.nsIDOMParser);
console.log("PARSING OF DOM COMPLETED ...");
return (parser.parseFromString(string, "text/html"));
};

data
will return you a string representation of a list, but it is actually still a string. Just check the type of data
with type(data)
. That means if you try using indexing on this string representation of a list as such data['fruits'][0]
, it will return you "[" as it is the first character of data['fruits']
You can do json.loads(data['fruits'])
to convert it back to a Python list so that you can interact with regular list indexing. There are 2 other ways you can convert it back to a Python list suggested here
You can try this, it looks up for the index containing this element, and it sets the index number as the int, then it checks if the int is greater then -1, so if it's 0 or more, then it means it found such an index - as arrays are 0 based.
string[] Selection = {"First", "Second", "Third", "Fourth"};
string Valid = "Third"; // You can change this to a Console.ReadLine() to
//use user input
int temp = Array.IndexOf(Selection, Valid); // it gets the index of 'Valid',
// in our case it's "Third"
if (temp > -1)
Console.WriteLine("Valid selection");
}
else
{
Console.WriteLine("Not a valid selection");
}

To open a workbook. Use xlapp.workbooks.Open()
where you have previously declared and instanitated xlapp as so.. Excel.Application xlapp = new Excel.Applicaton();
parameters are correct.
Next make sure you use the property Value2 when assigning a value to the cell using either the cells property or the range object.
First of all store $date=$_POST['your date field name'];
insert into **Your_Table Name** values('$date',**other fields**);
You must contain date in single cote (' ')

For those who intend to use venv
:
If you don't already have pip
for Python 3:
sudo apt install python3-pip
Install venv
package:
sudo apt install python3.7-venv
Create virtual environment (which will be bootstrapped with pip
by default):
python3.7 -m venv /path/to/new/virtual/environment
To activate the virtual environment, source
the appropriate script for the current shell, from the bin
directory of the virtual environment. The appropriate scripts for the different shells are:
bash/zsh – activate
fish – activate.fish
csh/tcsh – activate.csh
For example, if using bash:
source /path/to/new/virtual/environment/bin/activate
Optionally, to update pip
for the virtual environment (while it is activated):
pip install --upgrade pip
When you want to deactivate the virtual environment:
deactivate
How about:
Path.Combine(Path.GetTempPath(), DateTime.Now.Ticks.ToString() + "_" + Guid.NewGuid().ToString() + ".csv")
It is highly improbable that the computer will generate the same Guid at the same instant of time. The only weakness i see here is the performance impact DateTime.Now.Ticks will add.
Your problem seams to be located here:
SELECT @maxCode = CAST(MAX(CAST(SUBSTRING(Voucher_No,LEN(@startFrom)+1,LEN(Voucher_No)- LEN(@Prefix)) AS INT)) AS varchar(100)) FROM dbo.Journal_Entry;
SET @sCode=CAST(@maxCode AS INT)
As the error says, you're casting a string that contains a letter 'J' to an INT
which for obvious reasons is not possible.
Either fix SUBSTRING
or don't store the letter 'J' in the database and only prepend it when reading.
If anyone, fails to load because hes script violates the script-src "Content Security Policy" or "because unsafe-eval' is not an allowed", I will advice using my pretty-small module-injector as a dev-tools snippet, then you'll be able to load like this:

this solution works because:
re: VMware Workstation support for physical disks vs virtual disks.
I run Player with the VM Disk files on their own dedicated fast hard drive, independent from the OS hard drive. This allows both the OS and Player to simultaneously independently read/write to their own drives, the performance difference is noticeable, and a second WD Black or Raptor or SSD is cheap. Placing the VM disk file on a second drive also works with Microsoft Virtual PC.
I know this was posted a while ago, but in case anyone is searching for an answer and really wants to use a button element instead of an input element...
You can not use .attr('value')
or .val()
with a button in IE. IE reports both the .val() and .attr("value") as being the text label (content) of the button element instead of the actual value of the value attribute.
You can work around it by temporarily removing the button's label:
var getButtonValue = function($button) {
var label = $button.text();
$button.text('');
var buttonValue = $button.val();
$button.text(label);
return buttonValue;
}
There are a few other quirks with buttons in IE. I have posted a fix for the two most common issues here.
It also works well ...

pydoc is fantastic for generating documentation, but the documentation has to be written in the first place. You must have docstrings in your source code as was mentioned by RocketDonkey in the comments:
"""
This example module shows various types of documentation available for use
with pydoc. To generate HTML documentation for this module issue the
command:
pydoc -w foo
"""
class Foo(object):
"""
Foo encapsulates a name and an age.
"""
def __init__(self, name, age):
"""
Construct a new 'Foo' object.
:param name: The name of foo
:param age: The ageof foo
:return: returns nothing
"""
self.name = name
self.age = age
def bar(baz):
"""
Prints baz to the display.
"""
print baz
if __name__ == '__main__':
f = Foo('John Doe', 42)
bar("hello world")
The first docstring provides instructions for creating the documentation with pydoc. There are examples of different types of docstrings so you can see how they look when generated with pydoc.
You should rather use ViewPropertyAnimator. This animates the view to its future position and you don't need to force any layout params on the view after the animation ends. And it's rather simple.
myView.animate().x(50f).y(100f);
myView.animate().translateX(pixelInScreen)
Note: This pixel is not relative to the view. This pixel is the pixel position in the screen.
use Mixins for ES6 multiple Inheritence.
let classTwo = Base => class extends Base{
// ClassTwo Code
};
class Example extends classTwo(ClassOne) {
constructor() {
}
}
The thing that worked for me (and that I took from another stackoverflow response), is to set the flag:
Response.TrySkipIisCustomErrors = true;

>>> file = open('a.txt').read()
>>> file
>>> file.split('\n')
['this is line 1', 'this is line 2', '']
I'm on Linux, but I guess you just use \r\n
on Windows and it would also work
Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.
You've got:
//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]
Which translates into:
Get me all the elements that have an ID
that contains ctl00_btnAircraftMapCell
. Out of these elements, get any child elements that have a title
that contains Select Seat
.
What you actually want is:
//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]
Which translates into:
Get me all the anchor elements that have both: an id
that contains ctl00_btnAircraftMapCell
and a title
that contains Select Seat
.
Have a look at HttpUtility.ParseQueryString() It'll give you a NameValueCollection
instead of a dictionary, but should still do what you need.
The other option is to use string.Split()
.
string url = @"http://example.com/file?a=1&b=2&c=string%20param";
string[] parts = url.Split(new char[] {'?','&'});
///parts[0] now contains http://example.com/file
///parts[1] = "a=1"
///parts[2] = "b=2"
///parts[3] = "c=string%20param"
This selector should work but will be more efficient if you replace it with your suited markup:
//*[contains(@class, 'Test')]
Or, since we know the sought element is a div
:
//div[contains(@class, 'Test')]
But since this will also match cases like class="Testvalue"
or class="newTest"
, @Tomalak's version provided in the comments is better:
//div[contains(concat(' ', @class, ' '), ' Test ')]
If you wished to be really certain that it will match correctly, you could also use the normalize-space function to clean up stray whitespace characters around the class name (as mentioned by @Terry):
//div[contains(concat(' ', normalize-space(@class), ' '), ' Test ')]
Note that in all these versions, the * should best be replaced by whatever element name you actually wish to match, unless you wish to search each and every element in the document for the given condition.
This one worked for me in Bootstrap 4:

What you seem to be thinking is that most of the processing is handled in the node event loop. Node actually farms off the I/O work to threads. I/O operations typically take orders of magnitude longer than CPU operations so why have the CPU wait for that? Besides, the OS can handle I/O tasks very well already. In fact, because Node does not wait around it achieves much higher CPU utilisation.
By way of analogy, think of NodeJS as a waiter taking the customer orders while the I/O chefs prepare them in the kitchen. Other systems have multiple chefs, who take a customers order, prepare the meal, clear the table and only then attend to the next customer.
A better approach is to store the old value using .data. This spares the creation of a global var which you should stay away from and keeps the information encapsulated within the element. A real world example as to why Global Vars are bad is documented here
e.g
<script>
//look no global needed:)
$(document).ready(function(){
// Get the initial value
var $el = $('#myInputElement');
$el.data('oldVal', $el.val() );
$el.change(function(){
//store new value
var $this = $(this);
var newValue = $this.data('newVal', $this.val());
})
.focus(function(){
// Get the value when input gains focus
var oldValue = $(this).data('oldVal');
});
});
</script>
<input id="myInputElement" type="text">
I heartily recommended dbVis. The client runs on Mac, Windows and Linux and supports a variety of database servers, including PostgreSQL.
This is what we ended up using:
n = 3
d = dict(raw_input().split() for _ in range(n))
print d
Input:
A1023 CRT
A1029 Regulator
A1030 Therm
Output:
{'A1023': 'CRT', 'A1029': 'Regulator', 'A1030': 'Therm'}
Use the str_contains
function.
if (str_contains($str, "."))
{
echo 'Found it';
}
else
{
echo 'Not found.';
}
if (strpos($str, '.') !== FALSE)
{
echo 'Found it';
}
else
{
echo 'Not found.';
}
Note that you need to use the !==
operator. If you use !=
or <>
and the '.'
is found at position 0
, the comparison will evaluate to true because 0
is loosely equal to false
.
I was having the same, a fix seems to have been made in the source.
Double click and install the production certificate in your key chain. This might resolve the issue.
you could use look-ahead assertion for this:
^(?=.*\d).+$
The fix for the heartbleed
vulnerability has been backported to 1.0.1e-16
by Red Hat for Enterprise Linux see, and this is therefore the official fix that CentOS ships.
Replacing OpenSSL with the latest version from upstream (i.e. 1.0.1g) runs the risk of introducing functionality changes which may break compatibility with applications/clients in unpredictable ways, causes your system to diverge from RHEL, and puts you on the hook for personally maintaining future updates to that package. By replacing openssl using a simple make config && make && make install means that you also lose the ability to use rpm to manage that package and perform queries on it (e.g. verifying all the files are present and haven't been modified or had permissions changed without also updating the RPM database).
I'd also caution that crypto software can be extremely sensitive to seemingly minor things like compiler options, and if you don't know what you're doing, you could introduce vulnerabilities in your local installation.
I used this code:
Gson gson = new Gson();
HashMap<String, Object> fields = gson.fromJson(json, HashMap.class);
To get the first n
elements of an array, use
array.slice(0, n);
You can use RuleBasedNumberFormat. for example result will give you Ninety
ULocale locale = new ULocale(Locale.US); //us english
Double d = Double.parseDouble(90);
NumberFormat formatter = new RuleBasedNumberFormat(locale, RuleBasedNumberFormat.SPELLOUT);
String result = formatter.format(d);
It supports a wide range of languages.
Also, if you don't have the gradlew file in your current directory:
You can install gradle with homebrew with the following command:
$ brew install gradle
As mentioned in this answer. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):
$ gradle test
It is a good practice get the amount you need to store first then initialize the array.
for example, you would ask the user how many data he need to store and then initialize it, or query the component or argument of how many you need to store.
if you want a dynamic array you could use ArrayList()
and use al.add();
function to keep adding, then you can transfer it to a fixed array.
//Initialize ArrayList and cast string so ArrayList accepts strings (or anything
ArrayList<string> al = new ArrayList();
//add a certain amount of data
for(int i=0;i<x;i++)
{
al.add("data "+i);
}
//get size of data inside
int size = al.size();
//initialize String array with the size you have
String strArray[] = new String[size];
//insert data from ArrayList to String array
for(int i=0;i<size;i++)
{
strArray[i] = al.get(i);
}
doing so is redundant but just to show you the idea, ArrayList
can hold objects unlike other primitive data types and are very easy to manipulate, removing anything from the middle is easy as well, completely dynamic.same with List
and Stack
Add these to make changing text color simpler
myView.textColor = Color.BLACK // or Color.parseColor("#000000"), etc.
var TextView.textColor: Int
get() = currentTextColor
set(@ColorInt color) {
setTextColor(color)
}
myView.setTextColorRes(R.color.my_color)
fun TextView.setTextColorRes(@ColorRes colorRes: Int) {
val color = ContextCompat.getColor(context, colorRes)
setTextColor(color)
}
I am just adding example here because I think examples make it easier to understand.
In printf() they behave identically so you can use any either %d or %i. But they behave differently in scanf().
For example:
int main()
{
int num,num2;
scanf("%d%i",&num,&num2);// reading num using %d and num2 using %i
printf("%d\t%d",num,num2);
return 0;
}
Output:
You can see the different results for identical inputs.
num
:
We are reading num
using %d
so when we enter 010
it ignores the first 0
and treats it as decimal 10
.
num2
:
We are reading num2
using %i
.
That means it will treat decimals, octals, and hexadecimals differently.
When it give num2
010
it sees the leading 0
and parses it as octal.
When we print it using %d
it prints the decimal equivalent of octal 010
which is 8
.
if (($("#one").length > 0)){
alert('yes');
}
if (($("#two").length > 0)){
alert('yes');
}
if (($("#three").length > 0)){
alert('yes');
}
if (($("#four")).length == 0){
alert('no');
}
This is what you need :)
There's an even simpler solution - delete the cache folder at user/.android/built-cache and go back to android studio and sync with gradle again, if that still doesn't work delete the cache folder again, and restart android studio and re-import the project

Dates are always a nightmare. Answering your old question, perhaps this is the most elegant way:
eval(("new " + "/Date(1455418800000)/").replace(/\//g,""))
With eval we convert our string to javascript code. Then we remove the "/", into the replace function is a regular expression. As we start with new then our sentences will excecute this:
new Date(1455418800000)
Now, one thing I started using long time ago, is long values that are represented in ticks... why? well, localization and stop thinking in how is date configured in every server or every client. In fact, I use it too in databases.
Perhaps is quite late for this answer, but can help anybody arround here.
If you run the GWT compiler with the -localWorkers flag, the compiler will compile multiple permutations in parallel. This lets you use all the cores of a multi-core machine, for example -localWorkers 2 will tell the compiler to do compile two permutations in parallel. You won't get order of magnitudes differences (not everything in the compiler is parallelizable) but it is still a noticable speedup if you are compiling multiple permutations.
If you're willing to use the trunk version of GWT, you'll be able to use hosted mode for any browser (out of process hosted mode), which alleviates most of the current issues with hosted mode. That seems to be where the GWT is going - always develop with hosted mode, since compiles aren't likely to get magnitudes faster.
You don't have to load the whole product. Magentos collections are very powerful and smart.
$collection = Mage::getModel('catalog/product')->getCollection();
$collection->addAttributeToFilter('entity_id', $product->getId());
$collection->addAttributeToSelect('manufacturer');
$product = $collection->getFirstItem();
$manufacturer = $product->getAttributeText('manufacturer');
At the moment you call getFirstItem() the query will be executed and the result product is very minimal:
[status] => 1
[entity_id] => 38901
[type_id] => configurable
[attribute_set_id] => 9
[manufacturer] => 492
[manufacturer_value] => JETTE
[is_salable] => 1
[stock_item (Varien_Object)] => Array
(
[is_in_stock] => 1
)
You say you want to delete any column with the title "Percent Margin of Error" so let's try to make this dynamic instead of naming columns directly.
Sub deleteCol()
On Error Resume Next
Dim wbCurrent As Workbook
Dim wsCurrent As Worksheet
Dim nLastCol, i As Integer
Set wbCurrent = ActiveWorkbook
Set wsCurrent = wbCurrent.ActiveSheet
'This next variable will get the column number of the very last column that has data in it, so we can use it in a loop later
nLastCol = wsCurrent.Cells.Find("*", LookIn:=xlValues, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column
'This loop will go through each column header and delete the column if the header contains "Percent Margin of Error"
For i = nLastCol To 1 Step -1
If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) > 0 Then
wsCurrent.Columns(i).Delete Shift:=xlShiftToLeft
End If
Next i
End Sub
With this you won't need to worry about where you data is pasted/imported to, as long as the column headers are in the first row.
EDIT: And if your headers aren't in the first row, it would be a really simple change. In this part of the code: If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare)
change the "1" in Cells(1, i)
to whatever row your headers are in.
EDIT 2: Changed the For
section of the code to account for completely empty columns.
[Answer copied from a duplicate, now-deleted question.]
time()
is a very, very old function. It goes back to a day when the C language didn't even have type long
. Once upon a time, the only way to get something like a 32-bit type was to use an array of two int
s -- and that was when int
s were 16 bits.
So you called
int now[2];
time(now);
and it filled the 32-bit time into now[0]
and now[1]
, 16 bits at a time. (This explains why the other time-related functions, such as localtime
and ctime
, tend to accept their time arguments via pointers, too.)
Later on, dmr finished adding long
to the compiler, so you could start saying
long now;
time(&now);
Later still, someone realized it'd be useful if time()
went ahead and returned the value, rather than just filling it in via a pointer. But -- backwards compatibility is a wonderful thing -- for the benefit of all the code that was still doing time(&now)
, the time()
function had to keep supporting the pointer argument. Which is why -- and this is why backwards compatibility is not always such a wonderful thing -- if you're using the return value, you still have to pass NULL as a pointer:
long now = time(NULL);
(Later still, of course, we started using time_t
instead of plain long
for times, so that, for example, it can be changed to a 64-bit type, dodging the y2.038k problem.)
[P.S. I'm not actually sure the change from int [2]
to long
, and the change to add the return value, happened at different times; they might have happened at the same time. But note that when the time was represented as an array, it had to be filled in via a pointer, it couldn't be returned as a value, because of course C functions can't return arrays.]

As pointed out by others, you simply create mockAppender
and then create a LoggingEvent
instance which essentially listens to the logging event registered/happens inside mockAppender
.
Here is how it looks like in test:

import ch.qos.logback.classic.Logger;

import ch.qos.logback.core.Appender;
@RunWith(MockitoJUnitRunner.class)
public class TestLogEvent {
// your Logger
private Logger log = (Logger) LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
// here we mock the appender
@Mock
private Appender<ILoggingEvent> mockAppender;
// Captor is generic-ised with ch.qos.logback.classic.spi.LoggingEvent

private ArgumentCaptor<LoggingEvent> captorLoggingEvent;
/**

*/
@Before
public void setUp() {
log.addAppender(mockAppender);
}
/**

* Besides, it's good coding practise
*/
@After
public void teardown() {
log.detachAppender(mockAppender);
}
// Assuming this is your method
public void yourMethod() {
log.info("hello world");

If you have Android Studio .0.4.0, you can create a new folder in your build path, YourApp/libraries
. Copy the JAR file. There in, right click on it and "Add As Library". Now you have a popup. Just select your directory and press OK, and that's it.
Assuming you've created your certificates and private keys with Let's Encrypt in /etc/letsencrypt/live/you.com
:
openssl pkcs12 -export -in fullchain.pem -inkey privkey.pem -out pkcs.p12 \
-name letsencrypt
This combines your SSL certificate fullchain.pem
and your private key privkey.pem
into a single file, pkcs.p12
.
You'll be prompted for a password for pkcs.p12
.
The export
option specifies that a PKCS #12 file will be created rather than parsed (according to the manual).
keytool -importkeystore -destkeystore keystore.jks -srckeystore pkcs.p12 \
-srcstoretype PKCS12 -alias letsencrypt
If keystore.jks
doesn't exist, it will be created containing the pkcs.12
file created above. Otherwise, you'll import pkcs.12
into the existing keystore.
These instructions are derived from the post "Create a Java Keystore (.JKS) from Let's Encrypt Certificates" on this blog.
Here's more on the different kind of files in /etc/letsencrypt/live/you.com/
.
The other answer is correct, but for completeness, here are other ways:
List<SomeClass> list = mapper.readValue(jsonString, new TypeReference<List<SomeClass>>() { });
SomeClass[] array = mapper.readValue(jsonString, SomeClass[].class);
I had a similar problem.
I would also look at this answer: Is there a high resolution (microsecond, nanosecond) DateTime object available for the CLR?.
About half-way down is an answer by "Robert P" with some extension functions I found useful.
None of the above suggested solutions worked for me. I use Anaconda and found that opencv version 3.3.1 still had Sift enabled. If you want to test in isolated conda environment, try the following inspired from @A.Ametov's answer above
conda create -n testenv opencv=3.3.1
conda activate testenv
conda activate myenv
python
#Check version of opencv being used
>>> import cv2
>>> cv2.__version__
#Check if Sift is available
>>> cv2.xfeatures2d.SIFT_create()
<xfeatures2d_SIFT 000002A3478655B0>
In case you don't want to use a temporary variable, you can also do like this:
final int len = arr.length;
for (int i=0; i < (len/2); i++) {
arr[i] += arr[len - 1 - i]; // a = a+b
arr[len - 1 - i] = arr[i] - arr[len - 1 - i]; // b = a-b
arr[i] -= arr[len - 1 - i]; // a = a-b
}
If you are using VS2010 or later it is even easier than that

There is a library for this BarCode PHP. You just need to include a few files:
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
You can generate many types of barcodes, namely 1D or 2D. Add the required library:
require_once('class/BCGcode39.barcode.php');
Generate the colours:
// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);
After you have added all the codes, you will get this way:
Example
Since several have asked for an example here is what I was able to do to get it done
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
require_once('class/BCGcode128.barcode.php');
header('Content-Type: image/png');
$color_white = new BCGColor(255, 255, 255);
$code = new BCGcode128();
$code->parse('HELLO');
$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);
$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
If you want to actually create the image file so you can save it then change
$drawing = new BCGDrawing('', $color_white);
to
$drawing = new BCGDrawing('image.png', $color_white);
We can achieve this using flex-box very easily.
If we have three elements like Header, MiddleContainer and Footer. And we want to give some fixed height to Header and Footer. then we can write like this:
For React/RN(defaults are 'display' as flex and 'flexDirection' as column), in web css we'll have to specify the body container or container containing these as display: 'flex', flex-direction: 'column' like below:
container-containing-these-elements: {
display: flex,
flex-direction: column
}
header: {
height: 40,
},
middle-container: {
flex: 1, // this will take the rest of the space available.
},
footer: {
height: 100,
}
This seems to be already asked before:

You can do that with a single statement and a subquery in nearly all relational databases.
INSERT INTO targetTable(field1)
SELECT field1
FROM myTable
WHERE NOT(field1 IN (SELECT field1 FROM targetTable))
Certain relational databases have improved syntax for the above, since what you describe is a fairly common task. SQL Server has a MERGE
syntax with all kinds of options, and MySQL has optional INSERT OR IGNORE
syntax.
Edit: SmallSQL's documentation is fairly sparse as to which parts of the SQL standard it implements. It may not implement subqueries, and as such you may be unable to follow the advice above, or anywhere else, if you need to stick with SmallSQL.
Use trigger
to fire your own event. When ever you change class add trigger with name
$("#main").on('click', function () {
$("#chld").addClass("bgcolorRed").trigger("cssFontSet");
});
$('#chld').on('cssFontSet', function () {
alert("Red bg set ");
});
I had this problem when I installed MySQL 8.0.15 with the community installer. The my.ini file that came with the installer did not work correctly after it had been edited. I did a full manual install by downloading that zip folder. I was able to create my own my.ini file containing only the parameters that I was concerned about and it worked.
include the parameters in that my.ini file that you are concerned about. so something like this(just ensure that there is already a folder created for the datadir or else initialization won't work):
[mysqld]
basedire=C:\program files\MySQL\MySQL8.0
datadir=D:\MySQL\Data
....continue with whatever parameters you want to include
initialize the data directory by running these two commands in the command prompt:
cd C:\program files\MySQL\MySQL8.0\bin
mysqld --default-file=C:\program files\MySQL\MySQL8.0\my.ini --initialize
install the MySQL server as a service by running these two commands:
cd C:\program files\MySQL\MySQL8.0\bin
mysqld --install --default-file=C:\program files\MySQL\MySQL8.0\my.ini
finally, start the server for the first time by running these two commands:
cd C:\program files\MySQL\MySQL8.0\bin
mysqld --console
Another spin on the same theme:
protected void OnWindowSizeChanged(object sender, SizeChangedEventArgs e)
{
dataGrid.Width = e.NewSize.Width - (e.NewSize.Width * .1);
foreach (var column in dataGrid.Columns)
{
column.Width = dataGrid.Width / dataGrid.Columns.Count;
}
}
element.style.height = null;
output:
<div style="height:100px;">
// results:
<div style="">
You are going to need to call the SmsManager
class. You are probably going to need to use the STATUS_ON_ICC_READ
constant and maybe put what you get there into your apps local db so that you can keep track of what you have already read vs the new stuff for your app to parse through.
BUT bear in mind that you have to declare the use of the class in your manifest, so users will see that you have access to their SMS called out in the permissions dialogue they get when they install. Seeing SMS access is unusual and could put some users off. Good luck.
For the website ensure that IIS HTTP response headers setting and add new key X-UA-Compatible pointing to "IE=edge"
If you have access to the server, the most reliable way of doing this is to do it on the server itself, in IIS. Go in to IIS HTTP Response Headers. Add Name: X-UA-Compatible Value: IE=edge This will override your browser and your code.

I've coded simple String extension method, where you could specify if comparison is case sensitive or case senseless with boolean - see following answer:
You can't do that in Javascript from the browser... If I were you, I would use something like browserify. Write your code using commonjs modules and then compile the javascript file into one.

Your rewrite rule looks almost ok.
First make sure that your .htaccess
file is in your document root (the same place as index.php
) or it'll only affect the sub-folder it's in (and any sub-folders within that - recursively).
Next make a slight change to your rule so it looks something like:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [NC,L,QSA]
At the moment you're just matching on .
which is one instance of any character, you need at least .*
to match any number of instances of any character.
The $_GET['path']
variable will contain the fake directory structure, so /mvc/module/test
for instance, which you can then use in index.php to determine the Controller and actions you want to perform.
If you want the whole shebang installed in a sub-directory, such as /mvc/
or /framework/
the least complicated way to do it is to change the rewrite rule slightly to take that into account.
RewriteRule ^(.*)$ /mvc/index.php?path=$1 [NC,L,QSA]
And ensure that your index.php
is in that folder whilst the .htaccess
file is in the document root.
Alternative to $_GET['path']
(updated Feb '18 and Jan '19)
It's not actually necessary (nor even common now) to set the path as a $_GET
variable, many frameworks will rely on $_SERVER['REQUEST_URI']
to retrieve the same information - normally to determine which Controller to use - but the principle is exactly the same.
This does simplify the RewriteRule
slightly as you don't need to create the path parameter (which means the OP's original RewriteRule
will now work):
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /index.php [L,QSA]
However, the rule about installing in a sub-directory still applies, e.g.
RewriteRule ^.*$ /mvc/index.php [L,QSA]
The flags:
NC
= No Case (not case sensitive, not really necessary since there are no characters in the pattern)
L
= Last (it'll stop rewriting at after this Rewrite so make sure it's the last thing in your list of rewrites)
QSA
= Query String Append, just in case you've got something like ?like=penguins
on the end which you want to keep and pass to index.php.
It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:
[...] when looping through the
Iterable
value list, each Object instance is re-used, so it only keeps one instance around at a given time.
Section 6.16 Frame target names in the HTML 4.01 spec defines the meanings, but it is partly outdated. It refers to “windows”, whereas HTML5 drafts more realistically speak about “browsing contexts”, since modern browsers often use tabs instead of windows in this context.
Briefly, _self
is the default (current browsing context, i.e. current window or tab), so it is useful only to override a <base target=...>
setting. The value _parent
refers to the frameset that is the parent of the current frame, whereas _top
“breaks out of all frames” and opens the linked document in the entire browser window.
You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.
$("button").click(function() {
var $btn = $(this);
$btn.button('loading');
// simulating a timeout
setTimeout(function () {
$btn.button('reset');
}, 1000);
});
Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.

If you are using ReactTooltip
, to make the warning disappear, you can now add a wrapper
prop with a value of span
, like this:
<ReactTooltip wrapper="span" />
Since the span
is an inline element, it should no longer complain.
function isEmpty(val) {
if(val.length ==0 || val.length ==null){
return 'emptyForm';
}else{
return 'not emptyForm';
}
}
$(document).ready(function(){enter code here
$( "form" ).submit(function( event ) {
$('input').each(function(){
var getInputVal = $(this).val();
if(isEmpty(getInputVal) =='emptyForm'){
alert(isEmpty(getInputVal));
}else{
alert(isEmpty(getInputVal));
}
});
event.preventDefault();
});
});
Statement will be used for executing static SQL statements and it can't accept input parameters.
PreparedStatement will be used for executing SQL statements many times dynamically. It will accept input parameters.
You may use this too
Sub CopyPaste()
Sheet1.Range("A:A").Copy
Sheet2.Activate
col = 1
Do Until Sheet2.Cells(1, col) = ""
col = col + 1
Loop
Sheet2.Cells(1, col).PasteSpecial xlPasteValues
End Sub
I did it by setting an AncesterAdded event on the textField and the requesting focus in the window.
Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.
e.g. if you do this:
SELECT 1 / 2
you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.
e.g.
SELECT CAST(1 AS DECIMAL) / 2
gives 0.500000
I know I might get criticized for suggesting dynamic SQL, but sometimes it's a good solution. Just make sure you understand the security implications before you consider this.
DECLARE @add_a_b_func nvarchar(4000) = N'SELECT @c = @a + @b;';
DECLARE @add_a_b_parm nvarchar(500) = N'@a int, @b int, @c int OUTPUT';
DECLARE @result int;
EXEC sp_executesql @add_a_b_func, @add_a_b_parm, 2, 3, @c = @result OUTPUT;
PRINT CONVERT(varchar, @result); -- prints '5'
You can use:
set content=
for /f "delims=" %%i in ('type text.txt') do set content=!content! %%i
As mentioned above, if your data contains tab characters, commas, or newlines in your data then it's going to be very hard to export and import it with CSV. Values will overflow out of the fields and you will get errors. This problem is even worse if any of your long fields contain multi-line text with newline characters in them.
My method in these cases is to use the BCP command-line utility to export the data from SQL server, then use LOAD DATA INFILE .. INTO TABLE command in MySQL to read the data file back in. BCP is one of the oldest SQL Server command line utilities (dating back to the birth of SQL server - v6.5) but it is still around and still one of the easiest and most reliable ways to get data out.
To use this technique you need to create each destination table with the same or equivalent schema in MySQL. I do that by right clicking the Database in SQL enterprise manager, then Tasks->Generate Scripts... and create a SQL script for all the tables. You must then convert the script to MySQL compatible SQL by hand (definitely the worst part of the job) and finally run the CREATE TABLE commands on the MySQL database so you have matching tables to the SQL server versions column-wise, empty and ready for data.
Then, export the data from the MS-SQL side as follows.
bcp DatabaseName..TableName out TableName.dat -q -c -T -S ServerName -r \0 -t !\t!
(If you're using SQL Server Express, use a -S value like so: -S "ComputerName\SQLExpress")
That will create a file named TableName.dat, with fields delimited by ![tab]! and rows delimited by \0 NUL characters.
Now copy the .dat files into /tmp on the MySQL server and load on the MySQL side like so:
LOAD DATA INFILE '/tmp/TableName.dat' INTO TABLE TableName FIELDS TERMINATED BY '!\t!' LINES TERMINATED BY '\0';
Don't forget that the tables (TableName in this example) must be created already on the MySQL side.
This procedure is painfully manual when it comes to converting the SQL schema over, however it works for even the most difficult of data and because it uses flat files you never need to persuade SQL Server to talk to MySQL, or vice versa.
Add this android:screenOrientation="landscape"
to your <activity>
tag in the manifest for the specific activity that you want to be in landscape.
Edit:
To toggle the orientation from the Activity
code, call setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE)
other parameters can be found in the Android docs for ActivityInfo.
The unload() method was deprecated in jQuery version 1.8.
so if you are using versions older than 1.8
then use -
$(window).unload(function(){
alert("Goodbye!");
});
and if you are using 1.8 and higher
then use -
window.onbeforeunload = function() {
return "Bye now!";
};
hope this will work :-)
Simple and straightforward:
1) Create your recaptcha fields normally with this:
<div class="g-recaptcha" data-sitekey="YOUR_KEY_HERE"></div>
2) Load the script with this:
<script src="https://www.google.com/recaptcha/api.js?onload=CaptchaCallback&render=explicit" async defer></script>
3) Now call this to iterate over the fields and create the recaptchas:
<script type="text/javascript">
var CaptchaCallback = function() {
jQuery('.g-recaptcha').each(function(index, el) {
grecaptcha.render(el, {
'sitekey' : jQuery(el).attr('data-sitekey')
,'theme' : jQuery(el).attr('data-theme')
,'size' : jQuery(el).attr('data-size')
,'tabindex' : jQuery(el).attr('data-tabindex')
,'callback' : jQuery(el).attr('data-callback')
,'expired-callback' : jQuery(el).attr('data-expired-callback')
,'error-callback' : jQuery(el).attr('data-error-callback')
});
});
};
</script>
For me none of the solutions here solved it. Frustrated, I restarted my Macbook's iTerm terminal, and voila! My github authorization started working again.
Weird, but maybe iTerm has its own way of handling SSH authorizations or that my terminal session wasn't authorized somehow.
There are two ways to approach this.
Option 1: Update the Android Manifest If the settings Activity is always called from the same activity, you can make the relationship in the Android Manifest. Android will automagically show the 'back' button in the ActionBar
<activity
android:name=".SettingsActivity"
android:label="Setting Activity">
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.example.example.MainActivity" />
</activity>
Option 2: Change a setting for the ActionBar If you don't know which Activity will call the Settings Activity, you can create it like this. First in your activity that extends ActionBarActivity (Make sure your @imports match the level of compatibility you are looking for).
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings_test);
ActionBar actionBar = getSupportActionBar();
actionBar.setHomeButtonEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
}
Then, detect the 'back button' press and tell Android to close the currently open Activity.
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// app icon in action bar clicked; goto parent activity.
this.finish();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
That should do it!
I think it can't be simpler than this.

console.log(findDuplicates([ "q", "w", "w", "e", "i", "u", "r"]));

Above code will not work because, jQuery is not declared on the top of any library which uses jQuery ready function.
Just add water style="display:none";
to the <div>
Fiddles I say: http://jsfiddle.net/krY56/13/

Preferred to have a CSS Class .hidden
.hidden {

With after_request
we can handle the CORS response headers avoiding to add extra code to our endpoints:
### CORS section
@app.after_request
def after_request_func(response):
origin = request.headers.get('Origin')
if request.method == 'OPTIONS':
response = make_response()
response.headers.add('Access-Control-Allow-Credentials', 'true')
response.headers.add('Access-Control-Allow-Headers', 'Content-Type')
response.headers.add('Access-Control-Allow-Headers', 'x-csrf-token')
response.headers.add('Access-Control-Allow-Methods',
'GET, POST, OPTIONS, PUT, PATCH, DELETE')
if origin:
response.headers.add('Access-Control-Allow-Origin', origin)
else:
response.headers.add('Access-Control-Allow-Credentials', 'true')
if origin:
response.headers.add('Access-Control-Allow-Origin', origin)
return response
### end CORS section
Concluding from above answers, Here is the exact difference between full/strictly, complete and perfect binary trees
Full/Strictly binary tree :- Every node except the leaf nodes have two children
Complete binary tree :- Every level except the last level is completely filled and all the nodes are left justified.
Perfect binary tree :- Every node except the leaf nodes have two children and every level (last level too) is completely filled.
I would suggest using both SMS and HTTP. If the user is not signed in send their phone an SMS to notify them there's a message waiting.
That's how this Ericsson Labs service works: https://labs.ericsson.com/apis/mobile-java-push/
If you implement this yourself the tricky part is deleting the incoming SMS without the user seeing it. Or maybe it's ok if they see it in your case.
Looks like this works: Deleting SMS Using BroadCastReceiver - Android
Yes, writing code like this can be dangerous and you can potentially ruin someone's life because your application deleted an SMS it shouldn't have.
mkdirs()
will create the specified directory path in its entirety where mkdir()
will only create the bottom most directory, failing if it can't find the parent directory of the directory it is trying to create.
In other words mkdir()
is like mkdir
and mkdirs()
is like mkdir -p
.
For example, imagine we have an empty /tmp
directory. The following code
new File("/tmp/one/two/three").mkdirs();
would create the following directories:
/tmp/one
/tmp/one/two
/tmp/one/two/three
Where this code:
new File("/tmp/one/two/three").mkdir();
would not create any directories - as it wouldn't find /tmp/one/two
- and would return false
.
I'll try to provide a comprehensive answer here. Much of the points appear in other answers, but I found each answer incomplete, and some incorrect.
First and foremost, objectForKey:
is an NSDictionary
method, while valueForKey:
is a KVC protocol method required of any KVC complaint class - including NSDictionary.
Furthermore, as @dreamlax wrote, documentation hints that NSDictionary
implements its valueForKey:
method USING its objectForKey:
implementation. In other words - [NSDictionary valueForKey:]
calls on [NSDictionary objectForKey:]
.
This implies, that valueForKey:
can never be faster than objectForKey:
(on the same input key) although thorough testing I've done imply about 5% to 15% difference, over billions of random access to a huge NSDictionary. In normal situations - the difference is negligible.
Next: KVC protocol only works with NSString *
keys, hence valueForKey:
will only accept an NSString *
(or subclass) as key, whilst NSDictionary
can work with other kinds of objects as keys - so that the "lower level" objectForKey:
accepts any copy-able (NSCopying protocol compliant) object as key.
Last, NSDictionary's
implementation of valueForKey:
deviates from the standard behavior defined in KVC's documentation, and will NOT emit a NSUnknownKeyException
for a key it can't find - unless this is a "special" key - one that begins with '@' - which usually means an "aggregation" function key (e.g. @"@sum, @"@avg"
). Instead, it will simply return a nil when a key is not found in the NSDictionary - behaving the same as objectForKey:
Following is some test code to demonstrate and prove my notes.
- (void) dictionaryAccess {
NSLog(@"Value for Z:%@", [@{@"X":@(10), @"Y":@(20)} valueForKey:@"Z"]); // prints "Value for Z:(null)"
uint32_t testItemsCount = 1000000;
// create huge dictionary of numbers
NSMutableDictionary *d = [NSMutableDictionary dictionaryWithCapacity:testItemsCount];
for (long i=0; i<testItemsCount; ++i) {
// make new random key value pair:
NSString *key = [NSString stringWithFormat:@"K_%u",arc4random_uniform(testItemsCount)];
NSNumber *value = @(arc4random_uniform(testItemsCount));
[d setObject:value forKey:key];
}
// create huge set of random keys for testing.
NSMutableArray *keys = [NSMutableArray arrayWithCapacity:testItemsCount];
for (long i=0; i<testItemsCount; ++i) {
NSString *key = [NSString stringWithFormat:@"K_%u",arc4random_uniform(testItemsCount)];
[keys addObject:key];
}
NSDictionary *dict = [d copy];
NSTimeInterval vtotal = 0.0, ototal = 0.0;
NSDate *start;
NSTimeInterval elapsed;
for (int i = 0; i<10; i++) {
start = [NSDate date];
for (NSString *key in keys) {
id value = [dict valueForKey:key];
}
elapsed = [[NSDate date] timeIntervalSinceDate:start];
vtotal+=elapsed;
NSLog (@"reading %lu values off dictionary via valueForKey took: %10.4f seconds", keys.count, elapsed);
start = [NSDate date];
for (NSString *key in keys) {
id obj = [dict objectForKey:key];
}
elapsed = [[NSDate date] timeIntervalSinceDate:start];
ototal+=elapsed;
NSLog (@"reading %lu objects off dictionary via objectForKey took: %10.4f seconds", keys.count, elapsed);
}
NSString *slower = (vtotal > ototal) ? @"valueForKey" : @"objectForKey";
NSString *faster = (vtotal > ototal) ? @"objectForKey" : @"valueForKey";
NSLog (@"%@ takes %3.1f percent longer then %@", slower, 100.0 * ABS(vtotal-ototal) / MAX(ototal,vtotal), faster);
}
As to the cause, the <f:attribute>
is specific to the component itself (populated during view build time), not to the iterated row (populated during view render time).
There are several ways to achieve the requirement.
If your servletcontainer supports a minimum of Servlet 3.0 / EL 2.2, then just pass it as an argument of action/listener method of UICommand
component or AjaxBehavior
tag. E.g.
<h:commandLink action="#{bean.insert(item.id)}" value="insert" />
In combination with:
public void insert(Long id) {
// ...
}
This only requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped
.
You can even pass the entire item object:
<h:commandLink action="#{bean.insert(item)}" value="insert" />
with:
public void insert(Item item) {
// ...
}
On Servlet 2.5 containers, this is also possible if you supply an EL implementation which supports this, like as JBoss EL. For configuration detail, see this answer.
Use <f:param>
in UICommand
component. It adds a request parameter.
<h:commandLink action="#{bean.insert}" value="insert">
<f:param name="id" value="#{item.id}" />
</h:commandLink>
If your bean is request scoped, let JSF set it by @ManagedProperty
@ManagedProperty(value="#{param.id}")
private Long id; // +setter
Or if your bean has a broader scope or if you want more fine grained validation/conversion, use <f:viewParam>
on the target view, see also f:viewParam vs @ManagedProperty:
<f:viewParam name="id" value="#{bean.id}" required="true" />
Either way, this has the advantage that the datamodel doesn't necessarily need to be preserved for the form submit (for the case that your bean is request scoped).
Use <f:setPropertyActionListener>
in UICommand
component. The advantage is that this removes the need for accessing the request parameter map when the bean has a broader scope than the request scope.
<h:commandLink action="#{bean.insert}" value="insert">
<f:setPropertyActionListener target="#{bean.id}" value="#{item.id}" />
</h:commandLink>
In combination with
private Long id; // +setter
It'll be just available by property id
in action method. This only requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped
.
Bind the datatable value to DataModel<E>
instead which in turn wraps the items.
<h:dataTable value="#{bean.model}" var="item">
with
private transient DataModel<Item> model;
public DataModel<Item> getModel() {
if (model == null) {
model = new ListDataModel<Item>(items);
}
return model;
}
(making it transient
and lazily instantiating it in the getter is mandatory when you're using this on a view or session scoped bean since DataModel
doesn't implement Serializable
)
Then you'll be able to access the current row by DataModel#getRowData()
without passing anything around (JSF determines the row based on the request parameter name of the clicked command link/button).
public void insert() {
Item item = model.getRowData();
Long id = item.getId();
// ...
}
This also requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped
.
Use Application#evaluateExpressionGet()
to programmatically evaluate the current #{item}
.
public void insert() {
FacesContext context = FacesContext.getCurrentInstance();
Item item = context.getApplication().evaluateExpressionGet(context, "#{item}", Item.class);
Long id = item.getId();
// ...
}
Which way to choose depends on the functional requirements and whether the one or the other offers more advantages for other purposes. I personally would go ahead with #1 or, when you'd like to support servlet 2.5 containers as well, with #2.
You just needed to cast the unsigned char
into a char
as the string
class doesn't have a constructor that accepts unsigned char
:
unsigned char* uc;
std::string s( reinterpret_cast< char const* >(uc) ) ;
However, you will need to use the length argument in the constructor if your byte array contains nulls, as if you don't, only part of the array will end up in the string (the array up to the first null)
size_t len;
unsigned char* uc;
std::string s( reinterpret_cast<char const*>(uc), len ) ;
Another approach would be to add the following line to package.json
dependencies:
"package-name": "user/repo#branch"
For example:
"dependencies": {
... other dependencies ...
"react-native": "facebook/react-native#master"
}
And then do npm install
or yarn install
The xargs
command takes white space characters (tabs, spaces, new lines) as delimiters.
You can narrow it down only for the new line characters ('\n') with -d
option like this:
ls *.mp3 | xargs -d '\n' mplayer
It works only with GNU xargs.
For BSD systems, use the -0
option like this:
ls *.mp3 | xargs -0 mplayer
This method is simpler and works with the GNU xargs as well.
For MacOS:
ls *.mp3 | tr \\n \\0 | xargs -0 mplayer
hash.store(key, value) - Stores a key-value pair in hash.
Example:
hash #=> {"a"=>9, "b"=>200, "c"=>4}
hash.store("d", 42) #=> 42
hash #=> {"a"=>9, "b"=>200, "c"=>4, "d"=>42}
You need to reset the stream to the beginning:
stringAsStream.Seek(0, SeekOrigin.Begin);
Console.WriteLine("Differs from:\t" + (char)stringAsStream.ReadByte());
This can also be done by setting the Position
property to 0:
stringAsStream.Position = 0
From what I understand you want to make a navigation bar or something similar to it. What I recommend doing is making a list and editing the items from there. Just try this;
<ul>
<li class='item col-md-12 panel' id='gameplay-title'>Title</li>
<li class='item col-md-6 col-md-offset-3 panel' id='gameplay-scoreboard'>Scoreboard</li>
</ul>
And so on... To add more categories add another ul in there. Now, for the CSS you just need this;
ul {
list-style: none;
}
.item {
display: inline;
padding-right: 20px;
}
Just assign row to a particular index, using loc
:
df.loc[-1] = [2, 3, 4] # adding a row
df.index = df.index + 1 # shifting index
df = df.sort_index() # sorting by index
And you get, as desired:
A B C
0 2 3 4
1 5 6 7
2 7 8 9

I had exactly the same issue, after moving from old go version (installed from old PPA) to newer (1.2.1) default packages in ubuntu 14.04.
The first step was to purge existing go:
sudo apt-get purge golang*
Which outputs following warnings:
dpkg: warning: while removing golang-go, directory '/usr/lib/go/src' not empty so not removed
dpkg: warning: while removing golang-go.tools, directory '/usr/lib/go' not empty so not removed
It looks like removing go leaves some files behind, which in turn can confuse newer install. More precisely, installation itself will complete fine, but afterwards any go command, like "go get something" gives those "unrecognized import path" errors.
All I had to do was to remove those dirs first, reinstall golang, and all works like a charm (assuming you also set GOPATH)
# careful!
sudo rm -rf /usr/lib/go /usr/lib/go/src
sudo apt-get install golang-go golang-go.tools
You should write something like that :
var text = "this is some sample text that i want to replace";
var new_text = text.replace("want", "dont want");
document.write(new_text);
In case anyone wants to see the stats for every user in their codebase, a couple of my coworkers recently came up with this horrific one-liner:
git log --shortstat --pretty="%cE" | sed 's/\(.*\)@.*/\1/' | grep -v "^$" | awk 'BEGIN { line=""; } !/^ / { if (line=="" || !match(line, $0)) {line = $0 "," line }} /^ / { print line " # " $0; line=""}' | sort | sed -E 's/# //;s/ files? changed,//;s/([0-9]+) ([0-9]+ deletion)/\1 0 insertions\(+\), \2/;s/\(\+\)$/\(\+\), 0 deletions\(-\)/;s/insertions?\(\+\), //;s/ deletions?\(-\)//' | awk 'BEGIN {name=""; files=0; insertions=0; deletions=0;} {if ($1 != name && name != "") { print name ": " files " files changed, " insertions " insertions(+), " deletions " deletions(-), " insertions-deletions " net"; files=0; insertions=0; deletions=0; name=$1; } name=$1; files+=$2; insertions+=$3; deletions+=$4} END {print name ": " files " files changed, " insertions " insertions(+), " deletions " deletions(-), " insertions-deletions " net";}'

You might want to look into my fork of pbzx
here: https://github.com/NiklasRosenstein/pbzx
It allows you to stream pbzx files that are not wrapped in a XAR archive. I've experienced this with recent XCode Command-Line Tools Disk Images (eg. 10.12 XCode 8).
pbzx -n Payload | cpio -i
foreach (Control field in container.Controls)
{
if (field is TextBox)
((TextBox)field).Clear();
else if (field is ComboBox)
((ComboBox)field).SelectedIndex=0;
else
dgView.DataSource = null;
ClearAllText(field);
}
You should use as_json
method which converts ActiveRecord objects to Ruby Hashes despite its name
tasks_records = TaskStoreStatus.all
tasks_records = tasks_records.as_json
# You can now add new records and return the result as json by calling `to_json`
tasks_records << TaskStoreStatus.last.as_json
tasks_records << { :task_id => 10, :store_name => "Koramanagala", :store_region => "India" }
tasks_records.to_json
You can also convert any ActiveRecord objects to a Hash with serializable_hash
and you can convert any ActiveRecord results to an Array with to_a
, so for your example :
tasks_records = TaskStoreStatus.all
tasks_records.to_a.map(&:serializable_hash)
And if you want an ugly solution for Rails prior to v2.3
JSON.parse(tasks_records.to_json) # please don't do it
For easy understand can see my figure.
Rebase will change commit hash, so that if you want to avoid much of conflict, just use rebase when that branch is done/complete as stable.
You can save excel
as unicode
text, it is tab-delimited.
The USAGE-privilege in mysql simply means that there are no privileges for the user 'phpadmin'@'localhost' defined on global level *.*
. Additionally the same user has ALL-privilege on database phpmyadmin phpadmin.*
.
So if you want to remove all the privileges and start totally from scratch do the following:
Revoke all privileges on database level:
REVOKE ALL PRIVILEGES ON phpmyadmin.* FROM 'phpmyadmin'@'localhost';
Drop the user 'phpmyadmin'@'localhost'
DROP USER 'phpmyadmin'@'localhost';
Above procedure will entirely remove the user from your instance, this means you can recreate him from scratch.
To give you a bit background on what described above: as soon as you create a user the mysql.user
table will be populated. If you look on a record in it, you will see the user and all privileges set to 'N'
. If you do a show grants for 'phpmyadmin'@'localhost';
you will see, the allready familliar, output above. Simply translated to "no privileges on global level for the user". Now your grant ALL
to this user on database level, this will be stored in the table mysql.db
. If you do a SELECT * FROM mysql.db WHERE db = 'nameofdb';
you will see a 'Y'
on every priv.
Above described shows the scenario you have on your db at the present. So having a user that only has USAGE
privilege means, that this user can connect, but besides of SHOW GLOBAL VARIABLES; SHOW GLOBAL STATUS;
he has no other privileges.
<form (submit)="onSubmit()">
<input [(ngModel)]="playerName">
</form>
let playerName: string;
onSubmit() {
return this.playerName;
}
Using the code below you can extend the partial context class with a method that will take a collection of entity objects and bulk copy them to the database. Simply replace the name of the class from MyEntities to whatever your entity class is named and add it to your project, in the correct namespace. After that all you need to do is call the BulkInsertAll method handing over the entity objects you want to insert. Do not reuse the context class, instead create a new instance every time you use it. This is required, at least in some versions of EF, since the authentication data associated with the SQLConnection used here gets lost after having used the class once. I don't know why.

Sadly rabbit just chokes on large repos for me so is unusable, paga doesn't slow down browsing but also doesn't seem to try and recourse into directories to see if anything has changed.
You can also use "bold" and "italic" instead of "normal" here. "Verdana" can be used for fontname..
But another question is this: How do you set the color of the text You write?
Answer: You use the turtle.color() method or turtle.fillcolor(), like this:
turtle.fillcolor("blue")
or just:
turtle.color("orange")
These calls must come before the turtle.write() command..
I can think of plenty of scenarios where you might need to do this, particularly during a migration or development process. For instance, I just now had to create a new table by cross-joining two existing tables (as part of a complex set-up process), and then I needed to add a primary key after the event. You can drop the existing primary key column, and then do this.
ALTER TABLE my_table ADD `ID` INT NOT NULL AUTO_INCREMENT FIRST, ADD PRIMARY KEY (`ID`);
For a live system, it is not a good idea, and especially if there are other tables with foreign keys pointing to it.
$('#myImg').safeUrl({wanted:"http://example/nature.png",rm:"/myproject/images/anonym.png"});
$.fn.safeUrl=function(args){
var that=this;
if($(that).attr('data-safeurl') && $(that).attr('data-safeurl') === 'found'){
return that;
}else{
$.ajax({
url:args.wanted,
type:'HEAD',
error:
function(){
$(that).attr('src',args.rm)
},
success:
function(){
$(that).attr('src',args.wanted)
$(that).attr('data-safeurl','found');
}
});
}
return that;
};
Note : rm
means here risk managment .

As of May 2017, multiple FROM
s can be used in a single Dockerfile.
See "Builder pattern vs. Multi-stage builds in Docker" (by Alex Ellis) and PR 31257 by Tõnis Tiigi.
The general syntax involves adding
FROM
additional times within your Dockerfile - whichever is the lastFROM
statement is the final base image. To copy artifacts and outputs from intermediate images useCOPY --from=<base_image_number>
.
FROM golang:1.7.3 as builder
WORKDIR /go/src/github.com/alexellis/href-counter/
RUN go get -d -v golang.org/x/net/html
COPY app.go .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o app .
FROM alpine:latest
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=builder /go/src/github.com/alexellis/href-counter/app .
CMD ["./app"]
The result would be two images, one for building, one with just the resulting app (much, much smaller)

what is a base image?
A set of files, plus EXPOSE
'd ports, ENTRYPOINT
and CMD
.
You can add files and build a new image based on that base image, with a new Dockerfile
starting with a FROM
directive: the image mentioned after FROM
is "the base image" for your new image.
does it mean that if I declare
neo4j/neo4j
in aFROM
directive, that when my image is run the neo database will automatically run and be available within the container on port 7474?
Only if you don't overwrite CMD
and ENTRYPOINT
.
But the image in itself is enough: you would use a FROM neo4j/neo4j
if you had to add files related to neo4j
for your particular usage of neo4j
.
According to HTML 5.2:
When specified on an element, [the
hidden
attribute] indicates that the element is not yet, or is no longer, directly relevant to the page’s current state, or that it is being used to declare content to be reused by other parts of the page as opposed to being directly accessed by the user.
Examples include a tab list where some panels are not exposed, or a log-in screen that goes away after a user logs in. I like to call these things “temporally relevant” i.e. they are relevant based on timing.
On the other hand, ARIA 1.1 says:
[The
aria-hidden
state] indicates whether an element is exposed to the accessibility API.
In other words, elements with aria-hidden="true"
are removed from the accessibility tree, which most assistive technology honors, and elements with aria-hidden="false"
will definitely be exposed to the tree. Elements without the aria-hidden
attribute are in the "undefined (default)" state, which means user agents should expose it to the tree based on its rendering. E.g. a user agent may decide to remove it if its text color matches its background color.
Now let’s compare semantics. It’s appropriate to use hidden
, but not aria-hidden
, for an element that is not yet “temporally relevant”, but that might become relevant in the future (in which case you would use dynamic scripts to remove the hidden
attribute). Conversely, it’s appropriate to use aria-hidden
, but not hidden
, on an element that is always relevant, but with which you don’t want to clutter the accessibility API; such elements might include “visual flair”, like icons and/or imagery that are not essential for the user to consume.
The semantics have predictable effects in browsers/user agents. The reason I make a distinction is that user agent behavior is recommended, but not required by the specifications.
The hidden
attribute should hide an element from all presentations, including printers and screen readers (assuming these devices honor the HTML specs). If you want to remove an element from the accessibility tree as well as visual media, hidden
would do the trick. However, do not use hidden
just because you want this effect. Ask yourself if hidden
is semantically correct first (see above). If hidden
is not semantically correct, but you still want to visually hide the element, you can use other techniques such as CSS.
Elements with aria-hidden="true"
are not exposed to the accessibility tree, so for example, screen readers won’t announce them. This technique should be used carefully, as it will provide different experiences to different users: accessible user agents won’t announce/render them, but they are still rendered on visual agents. This can be a good thing when done correctly, but it has the potential to be abused.
Lastly, there is a difference in syntax between the two attributes.
hidden
is a boolean attribute, meaning if the attribute is present it is true—regardless of whatever value it might have—and if the attribute is absent it is false. For the true case, the best practice is to either use no value at all (<div hidden>...</div>
), or the empty string value (<div hidden="">...</div>
). I would not recommend hidden="true"
because someone reading/updating your code might infer that hidden="false"
would have the opposite effect, which is simply incorrect.
aria-hidden
, by contrast, is an enumerated attribute, allowing one of a finite list of values. If the aria-hidden
attribute is present, its value must be either "true"
or "false"
. If you want the "undefined (default)" state, remove the attribute altogether.

The solution based on omerkirk's answer involves:
autoOpen: false, width: "auto", height: "auto"
Here is a rough outline of code:

<a href="http://jsfiddle.net/yBNVr/1/show/" data-title="HD 16:9 ratio video" data-width="512" data-height="288"><img src="http://dummyimage.com/120x90/000/f00&text=HD+16-9+ratio+video" /></a></li>
</div>
$(function () {
var iframe = $('<iframe frameborder="0" marginwidth="0" marginheight="0" allowfullscreen></iframe>');
var dialog = $("<div></div>").append(iframe).appendTo("body").dialog({
autoOpen: false,
modal: true,
resizable: false,
width: "auto",

Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]
.I tried using @Aditya's method of generating an unsigned APK file and installing that, but when I went to install it on my Android tablet, it gave me an error of Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]
.
I imagine this is because the APK file wasn't signed and the tablet was not happy with this. So, after generating the React Native bundle file I was able to generate a signed APK file, as normal, via Android Studio.
By the way, our app is a fully functioning Android app that already exists in the Play Store and we are just adding React Native to it in bite-sized pieces, because it's awesome.
So to summarize, here were my steps:
1) Generate React Native bundle:
react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/<your-package-name>/src/main/assets/index.android.bu??ndle --assets-dest android/<your-package-name>/src/main/res/
2) Generate a Signed APK file from Android Studio.
3) Install Signed APK File to USB device:
adb -d install -r <path_to_signed_apk>
The -d
flag just tells adb
to install on the usb device attached, in the event that you have an emulator running as well. If you want to install on whatever an emulator, drop the -d
flag.
4) Profit!
I am not sure if this helps but I had the same problem.
You are using springSecurityFilterChain with CSRF protection. That means you have to send a token when you send a form via POST request. Try to add the next input to your form:
<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
Change setInterval("func",10000)
to either setInterval(funcName, 10000)
or setInterval("funcName()",10000)
. The former is the recommended method.
If you want to use @Html.EditorFor() you have to use jQuery ui and update your Asp.net Mvc to 5.2.6.0 with NuGet Package Manager.
@Html.EditorFor(m => m.EntryDate, new { htmlAttributes = new { @class = "datepicker" } })
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
<script>
$(document).ready(function(){
$('.datepicker').datepicker();
});
</script>
}
This worked for me:
public static void main(String[] s) {
Double d = Math.PI;
d = Double.parseDouble(String.format("%.3f", d)); // can be required precision
System.out.println(d);
}
There are already a few good answers to this question, but for the sake of completeness I wanted to point out that the applicable section of the C standard is 5.1.2.2.3/15 (which is the same as section 1.9/9 in the C++11 standard). This section states that operators can only be regrouped if they are really associative or commutative.
blazeroni already made it pretty clear, I just want to add few points.
<merge>

self.str = str(number)
new_object = new_class(2)
print(dir(new_object)) #total list attributes of new_object
attr_value = new_object.__dict__
print(attr_value) #Dictionary of attribute and value for new_class

1.A very direct and easy to use example, make object to be passed implement Serializable.
class Object implements Serializable{
String firstName;
String lastName;
}
2.pass object in bundle
Bundle bundle = new Bundle();
Object Object = new Object();
bundle.putSerializable("object", object);
3.get passed object from bundle as Serializable then cast to Object.
Object object = (Object) getArguments().getSerializable("object");
How about this.. used a string instead of list, but same thing.. string can be treated like a list in Python:
def comb(s, res):
if not s: return
res.add(s)
for i in range(0, len(s)):
t = s[0:i] + s[i + 1:]
comb(t, res)
res = set()
comb('game', res)
print(res)
For me In Xcode 10, this solution worked like a charm. Just go to the Recovered References folder and remove all files in red color and add it again with proper reference. If Recovered References folder was not found: Check for all missing files in the project (files in red colour) and try to add files references again.
If you want to style only the colors of the tooltips do as follow:
.tooltip-inner { background-color: #000; color: #fff; }
.tooltip.top .tooltip-arrow { border-top-color: #000; }
.tooltip.right .tooltip-arrow { border-right-color: #000; }
.tooltip.bottom .tooltip-arrow { border-bottom-color: #000; }
.tooltip.left .tooltip-arrow { border-left-color: #000; }
The following should do the trick:
div[class^='myclass'], div[class*=' myclass']{
color: #F00;
}
Edit: Added wildcard (*
) as suggested by David
You can use '';
to declaring NULL variable in Javascript
Pickling will serialize your list (convert it, and it's entries to a unique byte string), so you can save it to disk. You can also use pickle to retrieve your original list, loading from the saved file.
So, first build a list, then use pickle.dump
to send it to a file...

Not a documented 100% supported way. There is an approach sometimes used for calculating running totals called "quirky update" that suggests that it might update in order of clustered index if certain conditions are met but as far as I know this relies completely on empirical observation rather than any guarantee.
But what version of SQL Server are you on? If SQL2005+ you might be able to do something with row_number

I tried using the function method from jbaron above but found that I needed to keep the original array intact for use later, and creating a new array like this:
var newArray = referenceArray;
apparently creates by reference instead of value because when I removed an element from newArray the referenceArray also had it removed. So I decided to create a new array each time like this:
function newArrRemoveItem(array, item, newArray){
for(var i = 0; i < array.length; i++) {
if(array[i]!=item){
newArray.push(array[i]);
}
}
}
Then I use it like this in another function:
var vesselID = record.get('VesselID');
var otherVessels = new Array();
newArrRemoveItem(vesselArr,vesselID,otherVessels);
Now the vesselArr remains intact while each time I execute the above code the otherVessels array includes all but the latest vesselID element.
http sends/receives data as strings... this is just the way things are. You are looking to parse the string as json.

I experienced the same problem with FZ-client, while my notebook connected via WLAN and DSL/Router. In the Site Manager connection settings I was applied Host:ftp.domain-name, Encryption:Only use plain FTP (insecure) and User:username@domain-name. Then the FTP-client succesfully connected to my website server. More FTP connection information could be found in the CPanel of the webserver. Hope this helps.
If you use iOS 7 SDK, this is very simple.
Just add this line in your viewDidLoad method:
self.yourTableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
function load_tpl(selected=""){
$("#load_tpl").empty();
for(x in ds_tpl){
$("#load_tpl").append('<li><a id="'+ds_tpl[x]+'" href="#" >'+ds_tpl[x]+'</a></li>');
}
$.each($("#load_tpl a"),function(){
$(this).on("click",function(e){
alert(e.target.id);
});
});
}
$(document).ready(function(){
$('form').find("input[type=search]").each(function(ev)
{
$(this).attr("placeholder", "Search Whatever you want");
});
});
An another possible case is make sure that you have installed WCF Activation feature. Go to Server Manager > Features > Add Features

The best use of tags you should use:
<img src="" alt=""/>
Also you can use in HTML5:
<img src="" alt="">
These two are completely valid in HTML5 Pick one of them and stick with that.
Your code attempts to overwrite a string literal. This is undefined behaviour.
There are several ways to fix this:
malloc()
then strcpy()
then free()
;str
into an array and use strcpy()
;strdup()
.An Error "indicates serious problems that a reasonable application should not try to catch."
while
An Exception "indicates conditions that a reasonable application might want to catch."
Error along with RuntimeException
& their subclasses are unchecked
exceptions. All other Exception classes are checked
exceptions.
Checked exceptions are generally those from which a program can recover & it might be a good idea to recover from such exceptions programmatically. Examples include FileNotFoundException
, ParseException
, etc. A programmer is expected to check for these exceptions by using the try-catch block or throw it back to the caller
On the other hand we have unchecked exceptions. These are those exceptions that might not happen if everything is in order, but they do occur. Examples include ArrayIndexOutOfBoundException
, ClassCastException
, etc. Many applications will use try-catch
or throws
clause for RuntimeExceptions
& their subclasses but from the language perspective it is not required to do so. Do note that recovery from a RuntimeException
is generally possible but the guys who designed the class/exception deemed it unnecessary for the end programmer to check for such exceptions.
Errors are also unchecked exception & the programmer is not required to do anything with these. In fact it is a bad idea to use a try-catch
clause for Errors. Most often, recovery from an Error is not possible & the program should be allowed to terminate. Examples include OutOfMemoryError
, StackOverflowError
, etc.
Do note that although Errors are unchecked exceptions, we shouldn't try to deal with them, but it is ok to deal with RuntimeExceptions
(also unchecked exceptions) in code. Checked exceptions should be handled by the code.
It uses indentation
def func():
funcbody
if cond:
ifbody

long dateTime = DateTime.Now.Ticks;
Console.WriteLine(dateTime);
Console.WriteLine(new DateTime(dateTime));
Console.ReadKey();
There is also the DOM way of doing this in JavaScript:
// Create a div and set class
var new_row = document.createElement("div");
new_row.setAttribute("class", "aClassName");
// Add some text
new_row.appendChild(document.createTextNode("Some text"));
// Add it to the document body
document.body.appendChild(new_row);
You can use now() to set the value of a datetime column, but keep in mind that you can't use that as a default value.
Not sure what you mean with "class constructor" but I'd assume you mean one of the ones below.
Instance constructor:
Public Sub New()
End Sub
Shared constructor:
Shared Sub New()
End Sub
public static void main(String[] args) {
List<String> ls=new ArrayList<String>();
ls.add("1");
ls.add("2");
ls.add("3");
ls.add("4");
//Then you can use "foreache" loop to iterate.
for(String item:ls){
System.out.println(item);
}
}
os.path.dirname(os.path.abspath(__file__))
Should give you the path to a
.
But if b.py
is the file that is currently executed, then you can achieve the same by just doing
os.path.abspath(os.path.join('templates', 'blog1', 'page.html'))

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?
Like biegleux already said:
If you want to use the small, medium or large value on any text in your Android app, you can just create a dimens.xml
file in your values
folder and define the text size there with the following 3 lines:
<dimen name="text_size_small">14sp</dimen>
<dimen name="text_size_medium">18sp</dimen>
<dimen name="text_size_large">22sp</dimen>
Here is an example for a TextView with large text from the dimens.xml
file:
<TextView
android:id="@+id/hello_world"
android:text="hello world"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="@dimen/text_size_large"/>
So you have an entity that is updated, and you want to update it in the database with the least amount of code...
Concurrency is always tricky, but I am assuming that you just want your updates to win. Here is how I did it for my same case and modified the names to mimic your classes. In other words, just change attach
to add
, and it works for me:
public static void SaveBook(Model.Book myBook)
{
using (var ctx = new BookDBContext())
{
ctx.Books.Add(myBook);
ctx.Entry(myBook).State = System.Data.Entity.EntityState.Modified;
ctx.SaveChanges();
}
}
I prefer this approach because: you don't have to iterate over 2 collections, you can get at things other than "name" and "value" if you need to, and you can sanitize your values before you store them in the object (if you have default values that you don't wish to store, for example).
$.formObject = function($o) {
var o = {},
real_value = function($field) {
var val = $field.val() || "";
// additional cleaning here, if needed
return val;
};
if (typeof o != "object") {
$o = $(o);
}
$(":input[name]", $o).each(function(i, field) {
var $field = $(field),
name = $field.attr("name"),
value = real_value($field);
if (o[name]) {
if (!$.isArray(o[name])) {
o[name] = [o[name]];
}
o[name].push(value);
}
else {
o[name] = value;
}
});
return o;
}
Use like so:
var obj = $.formObject($("#someForm"));
Only tested in Firefox.
I know this is an old post but i want to share my experience.
HTML:
<input type="text" placeholder="Username or E-Mail" required data-required-message="E-Mail or Username is Required!">
Javascript (jQuery):
$('input[required]').on('invalid', function() {
this.setCustomValidity($(this).data("required-message"));
});
This is a very simple sample. I hope this can help to anyone.
