Using REQUIRES_NEW
is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED
- it will create a new transaction.
That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional
, it will create a new transaction.
So, with that in mind, if using REQUIRES_NEW
makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.
On rollback - using REQUIRES_NEW
will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations.
Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.
I had a similar use case during testing hibernate event listeners which are only called on commit.
The solution was to wrap the code to be persistent into another method annotated with REQUIRES_NEW
. (In another class) This way a new transaction is spawned and a flush/commit is issued once the method returns.
Keep in mind that this might influence all the other tests! So write them accordingly or you need to ensure that you can clean up after the test ran.
For me the thing that worked was the order in which the namespaces were defined in the xsi:schemaLocation tag : [ since the version was all good and also it was transaction-manager already ]
The error was with :
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/tx

AND RESOLVED WITH :

Autocomplete="Off"
doesn't work anymore.
Try using just a random string instead of "Off"
, for example Autocomplete="NoAutocomplete"
I hope it helps.
Try:
<label><input type=checkbox" value="check" onChange = {(e) => this.setState({check: !this.state.check.value})}/> Checkbox </label>
Using check: !check.value
means it is looking for the check
object, which you haven't declared.
You need to specify that you want the opposite value of this.state.check
.
in MySQL are
".myd" a database self and
".tmd" a temporal file.
But sometimes I see also ".sql".
It depends on your settings and/or export method.
You could also use a CSS "calc" to get the same effect instead of using the negative margin or transform properties (in case you want to use those properties for anything else).
.hero:after,
.hero:after {
z-index: -1;
position: absolute;
top: 98.1%;
left: calc(50% - 25px);
content: '';
width: 0;
height: 0;
border-top: solid 50px #e15915;
border-left: solid 50px transparent;
border-right: solid 50px transparent;
}
Currently it only works for the .dropdown-menu
:
.dropdown-menu .divider {
height: 1px;
margin: 9px 0;
overflow: hidden;
background-color: #e5e5e5;
}
If you want it for other use, in your own css, following the bootstrap.css create another one:
.divider {
height: 1px;
width:100%;
display:block; /* for use on default inline elements like span */
margin: 9px 0;
overflow: hidden;
background-color: #e5e5e5;
}
change this {% if loop.counter == 1 %}
to {% if forloop.counter == 1 %} {#your code here#} {%endfor%}
and this from {{ user }} {{loop.counter}}
to {{ user }} {{forloop.counter}}
More permanent solution would be to fill the missing values, in the output shown by command: locale
Output from locale
is:
$ locale
LANG=en_US.utf8
LANGUAGE=
LC_CTYPE="en_US.utf8"
LC_NUMERIC=es_ES.utf8
LC_TIME=es_ES.utf8
LC_COLLATE="en_US.utf8"
LC_MONETARY=es_ES.utf8
LC_MESSAGES="en_US.utf8"
LC_PAPER=es_ES.utf8
LC_NAME="en_US.utf8"
LC_ADDRESS="en_US.utf8"
LC_TELEPHONE="en_US.utf8"
LC_MEASUREMENT=es_ES.utf8
LC_IDENTIFICATION="en_US.utf8"
LC_ALL=
To Fill the missing values edit ~/.bashrc :
$ vim ~/.bashrc
Add the following lines after the above command (suppose you want en_US.UTF-8 to be your language):
export LANGUAGE="en_US.UTF-8"
export LC_ALL="en_US.UTF-8"
If this file is ReadOnly you would be needing to follow the steps mentioned by The GeekyBoy. The answer given by Dr Beco in Superuser has details relating to saving readonly files.
After saving the file do:
$ source ~/.bashrc
Now you wont be facing the same problem anymore.
Look at node-ffi.
node-ffi is a Node.js addon for loading and calling dynamic libraries using pure JavaScript. It can be used to create bindings to native libraries without writing any C++ code.
What is wrong with a git merge master
on the feature
branch? This will preserve the work you had, while keeping it separate from the mainline branch.
A--B--C------F--G
\ \
D--E------H
Edit: Ah sorry did not read your problem statement. You will need force as you performed a rebase
. All commands that modify the history will need the --force
argument. This is a failsafe to prevent you from losing work (the old D
and E
would be lost).
So you performed a git rebase
which made the tree look like (although partially hidden as D
and E
are no longer in a named branch):
A--B--C------F--G
\ \
D--E D'--E'
So, when trying to push your new feature
branch (with D'
and E'
in it), you would lose D
and E
.
could it be that you forgot to load it in the document ready function?
$(document).ready(function () {
//your jQuery function
});
I have been banging my head against the wall with a similar problem. The only thing that helped is following the steps in this post.
Setting CSS width to 1% or 100% of an element according to all specs I could find out is related to the parent. Although Blink Rendering Engine (Chrome) and Gecko (Firefox) at the moment of writing seems to handle that 1% or 100% (make a columns shrink or a column to fill available space) well, it is not guaranteed according to all CSS specifications I could find to render it properly.
One option is to replace table with CSS4 flex divs:
https://css-tricks.com/snippets/css/a-guide-to-flexbox/
That works in new browsers i.e. IE11+ see table at the bottom of the article.
The hint is, the output file is created even if you get this error. The automatic deconstruction of vector starts after your code executed. Elements in the vector are deconstructed as well. This is most probably where the error occurs. The way you access the vector is through vector::operator[]
with an index read from stream. Try vector::at()
instead of vector::operator[]
. This won't solve your problem, but will show which assignment to the vector causes error.
I use Portecle, and it works like a charm.
You, maybe the not the OP, but someone may have a directory called /var/run/docker.sock/
already due to how many times you hack and slash to get things right with docker (especially noobs). Delete that directory and try again.
This helped me on my way to getting it to work on Centos 7.
It's called setuptools. You run it with the "easy_install" command.
You can find the directory at http://pypi.python.org/
Just convert it to a date using NSDateFormatter and the "h:mm a" format and convert it back to a string using the "HH:mm" format. Check out this date formatting guide to familiarize yourself with this material.
let dateAsString = "6:35 PM"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "h:mm a"
let date = dateFormatter.dateFromString(dateAsString)
dateFormatter.dateFormat = "HH:mm"
let date24 = dateFormatter.stringFromDate(date!)
On Ubuntu Bionic 18.04, this works as desired:
$ echo -e "testing email via yourisp.com from command line\n\nsent on: $(date)" | mailx --append='FROM:Foghorn Leghorn <[email protected]>' -s "test cli email $(date)" -- [email protected]
For me as I have already xampp on 127.0.0.1 and django on 127.0.1.1 and i kept trying adding hosts
ALLOWED_HOSTS = ['127.0.0.1', 'localhost', 'www.yourdomain.com', '*', '127.0.1.1']
and i got the same error or (400) bad request
so I change the url to 127.0.1.1:(the used port)/project and voila !
you have to check what is your virtual network address, for me as i use bitnami django stack 2.2.3-1 on Linux i can check which port django is using. if you have an error ( 400 bad request ) then i guess django on different virtual network .. good luck
Currently you are confined to the container bound nature of using scripts within docs. If you create a new script inside outside of docs then you will be able to export information to a google spreadsheet and use it like a logging tool.
For example in your first code block
function setCheckboxes() {
// Add your spreadsheet data
var errorSheet = SpreadsheetApp.openById('EnterSpreadSheetIDHere').getSheetByName('EnterSheetNameHere');
var cell = errorSheet.getRange('A1').offset(errorSheet.getLastRow(),0);
// existing code
var checklist = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("checklist");
var checklist_data_range = checklist.getDataRange();
var checklist_num_rows = checklist_data_range.getNumRows();
// existing logger
Logger.log("checklist num rows: " + checklist_num_rows);
//We can pass the information to the sheet using cell.setValue()
cell.setValue(new Date() + "Checklist num rows: " + checklist_num_rows);
When I'm working with GAS I have two monitors ( you can use two windows ) set up with one containing the GAS environment and the other containing the SS so I can write information to and log.
You can use something like this.
$ cat test_file.txt
54 68 69 73 20 69 73 20 74 65 78 74 20 64 61 74 61 2e 0a 4f 6e 65 20 6d 6f 72 65 20 6c 69 6e 65 20 6f 66 20 74 65 73 74 20 64 61 74 61 2e
$ for c in `cat test_file.txt`; do printf "\x$c"; done;
This is text data.
One more line of test data.
To also get things outside the <html>...</html>
, most importantly the <!DOCTYPE ...>
declaration, you could walk through document.childNodes, turning each into a string:
const html = [...document.childNodes]
.map(node => nodeToString(node))
.join('\n') // could use '' instead, but whitespace should not matter.
function nodeToString(node) {
switch (node.nodeType) {
case node.ELEMENT_NODE:
return node.outerHTML
case node.TEXT_NODE:
// Text nodes should probably never be encountered, but handling them anyway.
return node.textContent
case node.COMMENT_NODE:
return `<!--${node.textContent}-->`
case node.DOCUMENT_TYPE_NODE:
return doctypeToString(node)
default:
throw new TypeError(`Unexpected node type: ${node.nodeType}`)
}
}
I published this code as document-outerhtml on npm.
edit Note the code above depends on a function doctypeToString
; its implementation could be as follows (code below is published on npm as doctype-to-string):
function doctypeToString(doctype) {
if (doctype === null) {
return ''
}
// Checking with instanceof DocumentType might be neater, but how to get a
// reference to DocumentType without assuming it to be available globally?
// To play nice with custom DOM implementations, we resort to duck-typing.
if (!doctype
|| doctype.nodeType !== doctype.DOCUMENT_TYPE_NODE
|| typeof doctype.name !== 'string'
|| typeof doctype.publicId !== 'string'
|| typeof doctype.systemId !== 'string'
) {
throw new TypeError('Expected a DocumentType')
}
const doctypeString = `<!DOCTYPE ${doctype.name}`
+ (doctype.publicId ? ` PUBLIC "${doctype.publicId}"` : '')
+ (doctype.systemId
? (doctype.publicId ? `` : ` SYSTEM`) + ` "${doctype.systemId}"`
: ``)
+ `>`
return doctypeString
}
Only OpenJDK 7. OpenJDK6 is basically the same code base as SUN's version, that's why it redirects you to the official Oracle site.
First, let's see what each function does:
regexObject.test( String )
Executes the search for a match between a regular expression and a specified string. Returns true or false.
string.match( RegExp )
Used to retrieve the matches when matching a string against a regular expression. Returns an array with the matches or
null
if there are none.
Since null
evaluates to false
,
if ( string.match(regex) ) {
// There was a match.
} else {
// No match.
}
Is there any difference regarding performance?
Yes. I found this short note in the MDN site:
If you need to know if a string matches a regular expression regexp, use regexp.test(string).
Is the difference significant?
The answer once more is YES! This jsPerf I put together shows the difference is ~30% - ~60% depending on the browser:
Use .test
if you want a faster boolean check. Use .match
to retrieve all matches when using the g
global flag.
I came up with my own version of the encodeURIComponent, because the posted solution has one problem, if there was a + present in the String, which should be encoded, it will converted to a space.
So here is my class:
import java.io.UnsupportedEncodingException;
import java.util.BitSet;
public final class EscapeUtils
{
/** used for the encodeURIComponent function */
private static final BitSet dontNeedEncoding;
static
{
dontNeedEncoding = new BitSet(256);
// a-z
for (int i = 97; i <= 122; ++i)
{
dontNeedEncoding.set(i);
}
// A-Z
for (int i = 65; i <= 90; ++i)
{
dontNeedEncoding.set(i);
}
// 0-9
for (int i = 48; i <= 57; ++i)
{
dontNeedEncoding.set(i);
}
// '()*
for (int i = 39; i <= 42; ++i)
{
dontNeedEncoding.set(i);
}
dontNeedEncoding.set(33); // !
dontNeedEncoding.set(45); // -
dontNeedEncoding.set(46); // .
dontNeedEncoding.set(95); // _
dontNeedEncoding.set(126); // ~
}
/**
* A Utility class should not be instantiated.
*/
private EscapeUtils()
{
}
/**
* Escapes all characters except the following: alphabetic, decimal digits, - _ . ! ~ * ' ( )
*
* @param input
* A component of a URI
* @return the escaped URI component
*/
public static String encodeURIComponent(String input)
{
if (input == null)
{
return input;
}
StringBuilder filtered = new StringBuilder(input.length());
char c;
for (int i = 0; i < input.length(); ++i)
{
c = input.charAt(i);
if (dontNeedEncoding.get(c))
{
filtered.append(c);
}
else
{
final byte[] b = charToBytesUTF(c);
for (int j = 0; j < b.length; ++j)
{
filtered.append('%');
filtered.append("0123456789ABCDEF".charAt(b[j] >> 4 & 0xF));
filtered.append("0123456789ABCDEF".charAt(b[j] & 0xF));
}
}
}
return filtered.toString();
}
private static byte[] charToBytesUTF(char c)
{
try
{
return new String(new char[] { c }).getBytes("UTF-8");
}
catch (UnsupportedEncodingException e)
{
return new byte[] { (byte) c };
}
}
}
If the only characters to consider are letters then you can do:
select X from myTable where upper(X) = lower(X)
But of course that won't filter out other characters, just letters.
It's likely that your output encoding is set to ASCII. Try using this before sending output:
Console.OutputEncoding = System.Text.Encoding.UTF8;
(MSDN link to supporting documentation.)
And here's a little console test app you may find handy:
C#
using System;
using System.Text;
public static class ConsoleOutputTest {
public static void Main() {
Console.OutputEncoding = System.Text.Encoding.UTF8;
for (var i = 0; i <= 1000; i++) {
Console.Write(Strings.ChrW(i));
if (i % 50 == 0) { // break every 50 chars
Console.WriteLine();
}
}
Console.ReadKey();
}
}
VB.NET
imports Microsoft.VisualBasic
imports System
public module ConsoleOutputTest
Sub Main()
Console.OutputEncoding = System.Text.Encoding.UTF8
dim i as integer
for i = 0 to 1000
Console.Write(ChrW(i))
if i mod 50 = 0 'break every 50 chars
Console.WriteLine()
end if
next
Console.ReadKey()
End Sub
end module
It's also possible that your choice of Console font does not support that particular character. Click on the Windows Tool-bar Menu (icon like C:.) and select Properties -> Font. Try some other fonts to see if they display your character properly:
Just paste this code into functions.php file:
add_filter('nav_menu_css_class' , 'special_nav_class' , 10 , 2);
function special_nav_class ($classes, $item) {
if (in_array('current-menu-item', $classes) ){
$classes[] = 'active ';
}
return $classes;
}

If you want to set the Cache-Control header, there's nothing in the IIS7 UI to do this, sadly.
You can however drop this web.config in the root of the folder or site where you want to set it:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<staticContent>
<clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="7.00:00:00" />
</staticContent>
</system.webServer>
</configuration>
That will inform the client to cache content for 7 days in that folder and all subfolders.
You can also do this by editing the IIS7 metabase via appcmd.exe
, like so:
\Windows\system32\inetsrv\appcmd.exe set config "Default Web Site/folder" -section:system.webServer/staticContent -clientCache.cacheControlMode:UseMaxAge \Windows\system32\inetsrv\appcmd.exe set config "Default Web Site/folder" -section:system.webServer/staticContent -clientCache.cacheControlMaxAge:"7.00:00:00"
in my case, I forget to add (or deleted accidentally) firebase core in build gradle
implementation 'com.google.firebase:firebase-core:xx.x.x'
Although similar in general cases ("run and get results for many tasks"), each function has some specific functionality for other cases:
asyncio.gather()
Returns a Future instance, allowing high level grouping of tasks:
import asyncio
from pprint import pprint
import random
async def coro(tag):
print(">", tag)
await asyncio.sleep(random.uniform(1, 3))
print("<", tag)
return tag
loop = asyncio.get_event_loop()
group1 = asyncio.gather(*[coro("group 1.{}".format(i)) for i in range(1, 6)])
group2 = asyncio.gather(*[coro("group 2.{}".format(i)) for i in range(1, 4)])
group3 = asyncio.gather(*[coro("group 3.{}".format(i)) for i in range(1, 10)])
all_groups = asyncio.gather(group1, group2, group3)
results = loop.run_until_complete(all_groups)
loop.close()
pprint(results)
All tasks in a group can be cancelled by calling group2.cancel()
or even all_groups.cancel()
. See also .gather(..., return_exceptions=True)
,
asyncio.wait()
Supports waiting to be stopped after the first task is done, or after a specified timeout, allowing lower level precision of operations:
import asyncio
import random
async def coro(tag):
print(">", tag)
await asyncio.sleep(random.uniform(0.5, 5))
print("<", tag)
return tag
loop = asyncio.get_event_loop()
tasks = [coro(i) for i in range(1, 11)]
print("Get first result:")
finished, unfinished = loop.run_until_complete(
asyncio.wait(tasks, return_when=asyncio.FIRST_COMPLETED))
for task in finished:
print(task.result())
print("unfinished:", len(unfinished))
print("Get more results in 2 seconds:")
finished2, unfinished2 = loop.run_until_complete(
asyncio.wait(unfinished, timeout=2))
for task in finished2:
print(task.result())
print("unfinished2:", len(unfinished2))
print("Get all other results:")
finished3, unfinished3 = loop.run_until_complete(asyncio.wait(unfinished2))
for task in finished3:
print(task.result())
loop.close()
Though late, I had to use that today and found a very useful php script here that will allow you to dynamically create a png file, much like the way rgba works.
background: url(rgba.php?r=255&g=100&b=0&a=50) repeat;
background: rgba(255,100,0,0.5);
The script can be downloaded here: http://lea.verou.me/wp-content/uploads/2009/02/rgba.zip
I know it may not be the perfect solution for everybody, but it's worth considering in some cases, since it saves a lot of time and works flawlessly. Hope that helps somebody!
Use this command in cmd:
adb shell pm uninstall -k com.packagename
For example:
adb shell pm uninstall -k com.fedmich.pagexray
The -k
flag tells the package manager to keep the cache and data directories around, even though the app is removed. If you want a clean uninstall, don't specify -k
.
So to start with some kind of answer : ) - You can't
I am not an expert, but as far as I understand DataFrames, they are not equal to rdd and DataFrame has no such thing as Partitioner.
Generally DataFrame's idea is to provide another level of abstraction that handles such problems itself. The queries on DataFrame are translated into logical plan that is further translated to operations on RDDs. The partitioning you suggested will probably be applied automatically or at least should be.
If you don't trust SparkSQL that it will provide some kind of optimal job, you can always transform DataFrame to RDD[Row] as suggested in of the comments.
Also check to see if you are missing the www in the url which was on my case
i was testing on http://www.mywebsite.com and in the facebook app i had set http://mywebsite.com
I would say "Yes". As "Matz" had said something like this in one of his talks, "Ruby objects have no types." Not all of it but the part that he is trying to get across to us. Why would anyone have said "Everything is an Object" then? To add he said "Data has Types not objects".
So we might enjoy this.
https://www.youtube.com/watch?v=1l3U1X3z0CE
But Ruby doesn't care to much about the type of object just the class. We use classes not types. All data then has a class.
12345.class
'my string'.class
They may also have ancestors
Object.ancestors
They also have meta classes but I'll save you the details on that.
Once you know the class then you'll be able to lookup what methods you may use for it. That's where the "data type" is needed. If you really want to get into details the look up...
"The Ruby Object Model"
This is the term used for how Ruby handles objects. It's all internal so you don't really see much of this but it's nice to know. But that's another topic.
Yes! The class is the data type. Objects have classes and data has types. So if you know about data bases then you know there are only a finite set of types.
text blocks numbers
Here's a simple helper function that I created modeled after the above answers, tailored to a Babel environment:
import { isEmpty } from 'lodash'
export default function unflattenEntities(entities, parent = {id: null}, tree = []) {
let children = entities.filter( entity => entity.parent_id == parent.id)
if (!isEmpty( children )) {
if ( parent.id == null ) {
tree = children
} else {
parent['children'] = children
}
children.map( child => unflattenEntities( entities, child ) )
}
return tree
}
An abstract class is a class that contains at least one abstract method, which is a method without any actual code in it, just the name and the parameters, and that has been marked as "abstract".
The purpose of this is to provide a kind of template to inherit from and to force the inheriting class to implement the abstract methods.
An abstract class thus is something between a regular class and a pure interface. Also interfaces are a special case of abstract classes where ALL methods are abstract.
See this section of the PHP manual for further reference.
A small Node.js HTTP server listening on port 9080, parsing GET or POST data and sending it back to the client as part of the response is:
var sys = require('sys'),
url = require('url'),
http = require('http'),
qs = require('querystring');
var server = http.createServer(
function (request, response) {
if (request.method == 'POST') {
var body = '';
request.on('data', function (data) {
body += data;
});
request.on('end',function() {
var POST = qs.parse(body);
//console.log(POST);
response.writeHead( 200 );
response.write( JSON.stringify( POST ) );
response.end();
});
}
else if(request.method == 'GET') {
var url_parts = url.parse(request.url,true);
//console.log(url_parts.query);
response.writeHead( 200 );
response.write( JSON.stringify( url_parts.query ) );
response.end();
}
}
);
server.listen(9080);
Save it as parse.js
, and run it on the console by entering "node parse.js".
In your Java file write the following piece of code...
ImageView Button = (ImageView)findViewById(R.id.yourButtonsId);
Button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.addCategory(Intent.CATEGORY_BROWSABLE);
intent.setData(Uri.parse("http://www.yourURL.com"));
startActivity(intent);
}
});
What about something like:
Alter Table Products
Add LastUpdate varchar(200) null
Do you need something more complex than this?
Mike Stall posted the code for one he wrote in c# here :
http://blogs.msdn.com/jmstall/archive/2006/10/20/rtf_5F00_html.aspx
With EF or LINQ to SQL:
var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();
With LINQ to Objects I suggest to use morelinq extension MaxBy
(get morelinq from nuget):
var item = items.MaxBy(i => i.Value);
To search for multiple matches in each file, we can sequence several Select-String calls:
Get-ChildItem C:\Logs |
where { $_ | Select-String -Pattern 'VendorEnquiry' } |
where { $_ | Select-String -Pattern 'Failed' } |
...
At each step, files that do not contain the current pattern will be filtered out, ensuring that the final list of files contains all of the search terms.
Rather than writing out each Select-String call manually, we can simplify this with a filter to match multiple patterns:
filter MultiSelect-String( [string[]]$Patterns ) {
# Check the current item against all patterns.
foreach( $Pattern in $Patterns ) {
# If one of the patterns does not match, skip the item.
$matched = @($_ | Select-String -Pattern $Pattern)
if( -not $matched ) {
return
}
}
# If all patterns matched, pass the item through.
$_
}
Get-ChildItem C:\Logs | MultiSelect-String 'VendorEnquiry','Failed',...
Now, to satisfy the "Logtime about 11:30 am" part of the example would require finding the log time corresponding to each failure entry. How to do this is highly dependent on the actual structure of the files, but testing for "about" is relatively simple:
function AboutTime( [DateTime]$time, [DateTime]$target, [TimeSpan]$epsilon ) {
$time -le ($target + $epsilon) -and $time -ge ($target - $epsilon)
}
PS> $epsilon = [TimeSpan]::FromMinutes(5)
PS> $target = [DateTime]'11:30am'
PS> AboutTime '11:00am' $target $epsilon
False
PS> AboutTime '11:28am' $target $epsilon
True
PS> AboutTime '11:35am' $target $epsilon
True

I faced this error while debugging my C# .Net project in Visual Studio 2017 Community edition. I was calling a native method by performing p/invoke on a C++ assembly loaded at run-time. I encountered the very same error reported by OP.
I realized that Visual Studio was launched with a user account which was not an administrator on the machine. Then I relaunched Visual Studio under a different user account which was an administrator on the machine. That's all. My problem got resolved and I didn't face the issue again.
One thing to note is that the method which was being invoked on C++ assembly was supposed to write few things in registry. I didn't go debugging the C++ code to do some RCA but I see a possibility that the whole thing was failing as administrative privileges are required to write registry in Windows 10 operating system. So earlier when Visual Studio was running under a user account which didn't have administrative privileges on the machine, then the native calls were failing.
If you downloaded the file from the internet, either separately or inside a .zip file or similar, it may have been "locked" because it is flagged as coming from the internet zone. Many programs will use this as a sign that the content should not be trusted.
The simplest solution is to right-click the file in Windows Explorer, select Properties, and along the bottom of this dialog, you should have an "Unblock" option. Remember to click OK to accept the change.
If you got the file from an archive, it is usually better to unblock the archive first, if the file is flagged as coming from the internet zone, and you unzip it, that flag might propagate to many of the files you just unarchived. If you unblock first, the unarchived files should be fine.
There's also a Powershell command for this, Unblock-File:
> Unblock-File *
Additionally, there are ways to write code that will remove the lock as well.
From the comments by @Defcon1: You can also combine Unblock-File
with Get-ChildItem
to create a pipeline that unblocks file recursively. Since Unblock-File
has no way to find files recursively by itself, you have to use Get-ChildItem
to do that part.

Well, some time passed since 2008 and it's time for some fresh answer. Since Django 1.5 you will be able to create custom User class. Actually, at the time I'm writing this, it's already merged into master, so you can try it out.
There's some information about it in docs or if you want to dig deeper into it, in this commit.
All you have to do is add AUTH_USER_MODEL
to settings with path to custom user class, which extends either AbstractBaseUser
(more customizable version) or AbstractUser
(more or less old User class you can extend).
For people that are lazy to click, here's code example (taken from docs):
from django.db import models
from django.contrib.auth.models import (
BaseUserManager, AbstractBaseUser
)
class MyUserManager(BaseUserManager):
def create_user(self, email, date_of_birth, password=None):
"""
Creates and saves a User with the given email, date of
birth and password.
"""
if not email:
raise ValueError('Users must have an email address')
user = self.model(
email=MyUserManager.normalize_email(email),
date_of_birth=date_of_birth,
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, username, date_of_birth, password):
"""
Creates and saves a superuser with the given email, date of
birth and password.
"""
u = self.create_user(username,
password=password,
date_of_birth=date_of_birth
)
u.is_admin = True
u.save(using=self._db)
return u
class MyUser(AbstractBaseUser):
email = models.EmailField(
verbose_name='email address',
max_length=255,
unique=True,
)
date_of_birth = models.DateField()
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
objects = MyUserManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['date_of_birth']
def get_full_name(self):
# The user is identified by their email address
return self.email
def get_short_name(self):
# The user is identified by their email address
return self.email
def __unicode__(self):
return self.email
def has_perm(self, perm, obj=None):
"Does the user have a specific permission?"
# Simplest possible answer: Yes, always
return True
def has_module_perms(self, app_label):
"Does the user have permissions to view the app `app_label`?"
# Simplest possible answer: Yes, always
return True
@property
def is_staff(self):
"Is the user a member of staff?"
# Simplest possible answer: All admins are staff
return self.is_admin
I apologize for resurecting this old thread, but I just wanted to let everyone know there is a very close Bootstrap like CSS framework specifically created for email styling, here is the link: http://zurb.com/ink/

Nginx prefers prefix-based location matches (not involving regular expression), that's why in your code block, /stash redirects are going to /.
The algorithm used by Nginx to select which location to use is described thoroughly here: https://www.digitalocean.com/community/tutorials/understanding-nginx-server-and-location-block-selection-algorithms#matching-location-blocks
Here is a simple example for saving to a directory(external usb drive) using Python version 2.7.10 with Sublime Text 2 editor:
import numpy as np
import matplotlib.pyplot as plt
X = np.linspace(-np.pi, np.pi, 256, endpoint = True)
C, S = np.cos(X), np.sin(X)
plt.plot(X, C, color = "blue", linewidth = 1.0, linestyle = "-")
plt.plot(X, S, color = "red", linewidth = 1.0, linestyle = "-")
plt.savefig("/Volumes/seagate/temp_swap/sin_cos_2.png", dpi = 72)
Try:
mmatrix = np.zeros((nrows, ncols))
Since the shape parameter has to be an int or sequence of ints
http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html
Otherwise you are passing ncols
to np.zeros
as the dtype.
One way, using regular expressions:
>>> s = "how much for the maple syrup? $20.99? That's ridiculous!!!"
>>> re.sub(r'[^\w]', ' ', s)
'how much for the maple syrup 20 99 That s ridiculous '
\w
will match alphanumeric characters and underscores
[^\w]
will match anything that's not alphanumeric or underscore
I've used various methods for scripting telnet sessions under unix, but the simplest one is probably a sequence of echo and sleep commands, with their output piped into telnet. Piping the output into another command is also a possibility.
Silly example
(echo password; echo "show ip route"; sleep 1; echo "quit" ) | telnet myrouter
This (basicallly) retrieves the routing table of a Cisco router.
In NuGet 3.0 the Get-Package
command is deprecated and replaced with Find-Package
command.
Find-Package Common.Logging -AllVersions
See the NuGet command reference docs for details.
This is the message shown if you try to use Get-Package in Visual Studio 2015.
This Command/Parameter combination has been deprecated and will be removed
in the next release. Please consider using the new command that replaces it:
'Find-Package [-Id] -AllVersions'
Or as @Yishai said, you can use the version number dropdown in the NuGet screen in Visual Studio.
I don’t know how to add a comment onto Steve’s answer, but I would like to recommend the
GHC libraries documentation,
and in there specifically the
Sublist functions in Data.List
Which is much better as a reference, than just reading the plain Haskell report.
Generically, a fold with a rule on when to create a new sublist to feed, should solve it too.
The above answers are correct but I calling spyder
within my virtualenv would still use my PATH
to look up the version of spyder in my default anaconda env. I found this answer which gave the following workaround:
source activate my_env # activate your target env with spyder installed
conda info -e # look up the directory of your conda env
find /path/to/my/env -name spyder # search for the spyder executable in your env
/path/to/my/env/then/to/spyder # run that executable directly
I chose this over modifying PATH
or adding a link to the executable at a higher priority in PATH
since I felt this was less likely to break other programs. However, I did add an alias to the executable in ~/.bash_aliases
.
I don't think it's bad to use any?
at all. I use it a lot. It's clear and concise.
However if you are concerned about all nil
values throwing it off, then you are really asking if the array has size > 0
. In that case, this dead simple extension (NOT optimized, monkey-style) would get you close.
Object.class_eval do
def size?
respond_to?(:size) && size > 0
end
end
> "foo".size?
=> true
> "".size?
=> false
> " ".size?
=> true
> [].size?
=> false
> [11,22].size?
=> true
> [nil].size?
=> true
This is fairly descriptive, logically asking "does this object have a size?". And it's concise, and it doesn't require ActiveSupport. And it's easy to build on.
Some extras to think about:
present?
from ActiveSupport.String
, that ignores whitespace (like present?
does).length?
for String
or other types where it might be more descriptive.Integer
and other Numeric
types, so that a logical zero returns false
.In general your .h contains the class defition, which is all your data and all your method declarations. Like this in your case:
A2DD.h:
class A2DD
{
private:
int gx;
int gy;
public:
A2DD(int x,int y);
int getSum();
};
And then your .cpp contains the implementations of the methods like this:
A2DD.cpp:
A2DD::A2DD(int x,int y)
{
gx = x;
gy = y;
}
int A2DD::getSum()
{
return gx + gy;
}
The previous answers using the ISNULL
function are correct only for MS Sql Server. The COALESCE
function will also work in SQL Server. But will also work in standard SQL database systems. In the given example:
SELECT sum(COALESCE(TotalHoursM,0))
+ COALESCE(TotalHoursT,0)
+ COALESCE(TotalHoursW,0)
+ COALESCE(TotalHoursTH,0)
+ COALESCE(TotalHoursF,0) AS TOTAL FROM LeaveRequest
This is identical to the ISNULL
solution with the only difference being the name of the function. Both work in SQL Server but, COALESCE
is ANSI standard and ISNULL
is not. Also, COALESCE
is more flexible.
ISNULL
will only work with two parameters. If the first parameter is NULL then the value of the second parameter is returned, else the value of the first is returned.
COALESCE will take 2 to 'n' (I don't know the limit of 'n') parameters and return the value of the first parameter that is not NULL
. When there are only two parameters the effect is the same as ISNULL
.
For me it was just a matter of changing the path variable to: 'C:\Program Files\Mozilla Firefox' instead of 'C:\Program Files (x86)\Mozilla Firefox'
One should not recommend this as a general solution, but for one-off deletion of rows in a database that is not in production or in active use, you may be able to temporarily disable triggers on the tables in question.
In my case, I'm in development mode and have a couple of tables that reference one another via foreign keys. Thus, deleting their contents isn't quite as simple as removing all of the rows from one table before the other. So, for me, it worked fine to delete their contents as follows:
ALTER TABLE table1 DISABLE TRIGGER ALL;
ALTER TABLE table2 DISABLE TRIGGER ALL;
DELETE FROM table1;
DELETE FROM table2;
ALTER TABLE table1 ENABLE TRIGGER ALL;
ALTER TABLE table2 ENABLE TRIGGER ALL;
You should be able to add WHERE clauses as desired, of course with care to avoid undermining the integrity of the database.
There's some good, related discussion at http://www.openscope.net/2012/08/23/subverting-foreign-key-constraints-in-postgres-or-mysql/
You can specify that the data to be returned is not JSON using responseType
.
In your example, you can use a responseType
string value of text
, like this:
return this.http.post(
'http://10.0.1.19/login',
{email, password},
{responseType: 'text'})
The full list of options for responseType
is:
json
(the default)text
arraybuffer
blob
See the docs for more information.
I think this should help. Trick is to bind the contextmenu event.
<script type="text/javascript" language="javascript">
$(function() {
$(this).bind("contextmenu", function(e) {
e.preventDefault();
});
});
</script>
Use UIWindow
or UIView
's safeAreaInsets

// height - UIApplication.shared.keyWindow!.safeAreaInsets.bottom
// On iPhoneX
// UIApplication.shared.keyWindow!.safeAreaInsets.top = 44
// UIApplication.shared.keyWindow!.safeAreaInsets.bottom = 34
// Other devices
// UIApplication.shared.keyWindow!.safeAreaInsets.top = 0
// UIApplication.shared.keyWindow!.safeAreaInsets.bottom = 0
// example
let window = UIApplication.shared.keyWindow!
let viewWidth = window.frame.size.width
let viewHeight = window.frame.size.height - window.safeAreaInsets.bottom
let viewFrame = CGRect(x: 0, y: 0, width: viewWidth, height: viewHeight)
let aView = UIView(frame: viewFrame)
aView.backgroundColor = .red
view.addSubview(aView)
aView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
if you fetching it from database then
<select id="cmbMake" name="Make" >
<option value="">Select Manufacturer</option>
<?php $s2="select * from <tablename>";
$q2=mysql_query($s2);
while($rw2=mysql_fetch_array($q2)) {
?>
<option value="<?php echo $rw2['id']; ?>"><?php echo $rw2['carname']; ?></option><?php } ?>
</select>
You can use Ctrl + /. This works for me.
There is no inherent ordering to a table. So, the row number itself is a meaningless metric.
However, you can get the row number of a result set by using the ROWNUM psuedocolumn or the ROW_NUMBER()
analytic function, which is more powerful.
As there is no ordering to a table both require an explicit ORDER BY clause in order to work.
select rownum, a.*
from ( select *
from student
where name like '%ram%'
order by branch
) a
or using the analytic query
select row_number() over ( order by branch ) as rnum, a.*
from student
where name like '%ram%'
Your syntax where name is like ...
is incorrect, there's no need for the IS, so I've removed it.
The ORDER BY here relies on a binary sort, so if a branch starts with anything other than B the results may be different, for instance b
is greater than B
.
Hoping to provide a more nuanced answer than any of the ones here, especially as some things have changed since this was originally asked ~4 years ago, and because many of the top-voted answers claiming that you have to set this up as two separate applications are not accurate.
You have two primary architecture options:
These might look something like this:
Option 1 (Client/Server Architecture):
Option 2 (Hybrid Architecture):
The decision between these two will depend on your / your team's experience, as well as the complexity of your UI. The first option is good if you have a lot of JS experience, want to keep your front-end / back-end developers separate, or want to write your entire application as a React single-page-app. The second option is generally better if you are more familiar with Django and want to move quickly while also using React for some parts of your app. I find it's a particularly good fit for full-stack solo-developers.
There is a lot more information in the series "Modern JavaScript for Django Developers", including choosing your architecture, integrating your JS build into a Django project and building a single-page React app.
Full disclosure, I'm the author of that series.
const int n = snprintf(NULL, 0, "%lu", ulong_value);
assert(n > 0);
char buf[n+1];
int c = snprintf(buf, n+1, "%lu", ulong_value);
assert(buf[n] == '\0');
assert(c == n);
You are going wrong here:
int retval = chooser.showOpenDialog(null);
public boolean accept(File directory, String fileName) {`
return fileName.endsWith(".txt");`
}
You first show the file chooser dialog and then apply the filter! This wont work. First apply the filter and then show the dialog:
public boolean accept(File directory, String fileName) {
return fileName.endsWith(".txt");
}
int retval = chooser.showOpenDialog(null);
If you are accessing scoped beans within Spring Web MVC, i.e. within a request that is processed by the Spring DispatcherServlet, or DispatcherPortlet, then no special setup is necessary: DispatcherServlet and DispatcherPortlet already expose all relevant state.
If you are runnning outside of Spring MVC ( Not processed by DispatchServlet) you have to use the RequestContextListener
Not just ContextLoaderListener
.
Add the following in your web.xml
<listener>
<listener-class>
org.springframework.web.context.request.RequestContextListener
</listener-class>
</listener>
That will provide session to Spring in order to maintain the beans in that scope
Update :
As per other answers , the @Controller
only sensible when you are with in Spring MVC Context, So the @Controller is not serving actual purpose in your code. Still you can inject your beans into any where with session scope / request scope ( you don't need Spring MVC / Controller to just inject beans in particular scope) .
Update :
RequestContextListener exposes the request to the current Thread only.
You have autowired ReportBuilder in two places
1. ReportPage
- You can see Spring injected the Report builder properly here, because we are still in Same web Thread. i did changed the order of your code to make sure the ReportBuilder injected in ReportPage like this.
log.info("ReportBuilder name: {}", reportBuilder.getName());
reportController.getReportData();
i knew the log should go after as per your logic , just for debug purpose i added .
2. UselessTasklet
- We got exception , here because this is different thread created by Spring Batch , where the Request is not exposed by RequestContextListener
.
You should have different logic to create and inject ReportBuilder
instance to Spring Batch ( May Spring Batch Parameters and using Future<ReportBuilder>
you can return for future reference)
First you need to start karma server with
karma start
Then, you can use grep to filter a specific test or describe block:

The time() function displays the seconds between now and the unix epoch , 01 01 1970 (00:00:00 GMT). The strtotime() transforms a normal date format into a time() format. So the representation of that date into seconds will be : 1388516401

If you're using Angular's ng-repeat to populate the table hackel's jquery snippet will not work by placing it in the document load event. You'll need to run the snippet after angular has finished rendering the table.
To trigger an event after ng-repeat has rendered try this directive:
var app = angular.module('myapp', [])
.directive('onFinishRender', function ($timeout) {
return {
restrict: 'A',
link: function (scope, element, attr) {
if (scope.$last === true) {
$timeout(function () {
scope.$emit('ngRepeatFinished');
});
}
}
}
});
Complete example in angular: http://jsfiddle.net/ADukg/6880/
I got the directive from here: Use AngularJS just for routing purposes
I've had good results with Apache Tika. Its purpose is the extraction of metadata and text from content, hence the underlying parser is tuned accordingly out of the box.
Tika can be run as a server, is trivial to run / deploy in a Docker container, and from there can be accessed via Python bindings.

Connecting to PostgreSQL via SSH Tunneling
In the event that you don't want to open port 5432 to any traffic, or you don't want to configure PostgreSQL to listen to any remote traffic, you can use SSH Tunneling to make a remote connection to the PostgreSQL instance. Here's how:
The sign in such cases (i.e when one or both operands are negative) is implementation-defined. The spec says in §5.6/4 (C++03),
The binary / operator yields the quotient, and the binary % operator yields the remainder from the division of the first expression by the second. If the second operand of / or % is zero the behavior is undefined; otherwise (a/b)*b + a%b is equal to a. If both operands are nonnegative then the remainder is nonnegative; if not, the sign of the remainder is implementation-defined.
That is all the language has to say, as far as C++03 is concerned.
I think Jason's right. If your "Delete" action is a minimal one, make that be in a form by itself, and line it up with the other buttons so as to make the interface look like one unified form, even if it's not.
Or, of course, redesign your interface, and let people delete somewhere else entirely which doesn't require them to see the enormo-form at all.

If you don't know that you will get an array of dictionaries or single dictionary in the response from server you need to check whether the result contains an array or not.
In my case always receiving an array of dictionaries except once. So, to handle that I used the below code for swift 3.
if let str = strDict["item"] as? Array<Any>
Here as? Array checks whether the obtained value is array (of dictionary items). In else case you can handle if it is single dictionary item which is not kept inside an array.
There's multiple ways of doing things in batch, so if escaping with a double percent %%
isn't working for you, then you could try something like this:
set olddir=%CD%
cd /d "path of folder"
del "file name/ or *.txt etc..."
cd /d "%olddir%"
How this works:
set olddir=%CD%
sets the variable "olddir"
or any other variable name you like to the directory
your batch file was launched from.
cd /d "path of folder"
changes the current directory the batch will be looking at. keep the
quotations and change path of folder to which ever path you aiming for.
del "file name/ or *.txt etc..."
will delete the file in the current directory your batch is looking at, just don't add a directory path before the file name and just have the full file name or, to delete multiple files with the same extension with *.txt
or whatever extension you need.
cd /d "%olddir%"
takes the variable saved with your old path and goes back to the directory you started the batch with, its not important if you don't want the batch going back to its previous directory path, and like stated before the variable name can be changed to whatever you wish by changing the set olddir=%CD% line
.
That's one of the few legitimate jobs for cat
:
openssl verify -verbose -CAfile <(cat Intermediate.pem RootCert.pem) UserCert.pem
Update:
As Greg Smethells points out in the comments, this command implicitly trusts Intermediate.pem. I recommend reading the first part of the post Greg references (the second part is specifically about pyOpenSSL and not relevant to this question).
In case the post goes away I'll quote the important paragraphs:
Unfortunately, an "intermediate" cert that is actually a root / self-signed will be treated as a trusted CA when using the recommended command given above:
$ openssl verify -CAfile <(cat geotrust_global_ca.pem rogue_ca.pem) fake_sometechcompany_from_rogue_ca.com.pem fake_sometechcompany_from_rogue_ca.com.pem: OK
It seems openssl will stop verifying the chain as soon as a root certificate is encountered, which may also be Intermediate.pem if it is self-signed. In that case RootCert.pem is not considered. So make sure that Intermediate.pem is coming from a trusted source before relying on the command above.
If you are passing package name as parameter to any of your user defined function then use the below code :
Intent intent=new Intent(Intent.ACTION_DELETE);
intent.setData(Uri.parse("package:"+packageName));
startActivity(intent);
To mimic Excel CSV:
public static string Convert(DataTable dt)
{
StringBuilder sb = new StringBuilder();
IEnumerable<string> columnNames = dt.Columns.Cast<DataColumn>().
Select(column => column.ColumnName);
sb.AppendLine(string.Join(",", columnNames));
foreach (DataRow row in dt.Rows)
{
IEnumerable<string> fields = row.ItemArray.Select(field =>
{
string s = field.ToString().Replace("\"", "\"\"");
if(s.Contains(','))
s = string.Concat("\"", s, "\"");
return s;
});
sb.AppendLine(string.Join(",", fields));
}
return sb.ToString().Trim();

I don't know about CSS but this Javascript code should work:

}
else if(typeof document.documentElement != 'undefined' && typeof document.documentElement.clientWidth != 'undefined' && document.documentElement.clientWidth != 0)
{
w = document.documentElement.clientWidth; //IE
h = document.documentElement.clientHeight;
}
else{
w = document.body.clientWidth; //IE
h = document.body.clientHeight;
}
return {'width':w, 'height': h};
}
if(parseInt(getBrowserSize().width) < 1026){
document.getElementById("fadeshow1").style.display = "none";

MM => 2 digit month (you must type MM in ALL CAPS)
dd => 2 digit "day of the month"
HH => 2-digit "hour in day" (0 to 23)
mm => 2-digit minute (you must type mm in lowercase)
ss => 2-digit seconds
SSS => milliseconds
So "yyyy-MM-dd HH:mm:ss" returns "2018-01-05 09:49:32"
But "MMM dd, yyyy hh:mm a" returns "Jan 05, 2018 09:49 am"
The so-called examples at https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html show only output. They do not tell you what formats to use!
In chrome, you can apply this css if you need to apply ellipsis on multiple lines.
You can also add width in your css to specify element of certain width:

overflow: hidden;_x000D_
display: -webkit-box;_x000D_
-webkit-line-clamp: 3;_x000D_
-webkit-box-orient: vertical;_x000D_
}
_x000D_

Cookies are only sent at the time of the request, and therefore cannot be retrieved as soon as it is assigned (only available after reloading).
Once the cookies have been set, they can be accessed on the next page load with the $_COOKIE or $HTTP_COOKIE_VARS arrays.
If output exists prior to calling this function, setcookie() will fail and return FALSE. If setcookie() successfully runs, it will return TRUE. This does not indicate whether the user accepted the cookie.
Cookies will not become visible until the next loading of a page that the cookie should be visible for. To test if a cookie was successfully set, check for the cookie on a next loading page before the cookie expires. Expire time is set via the expire parameter. A nice way to debug the existence of cookies is by simply calling print_r($_COOKIE);.
dynDiv.Attributes["class"] = "myCssClass";
The number in parentheses specifies the precision of fractional seconds to be stored. So, (0)
would mean don't store any fraction of a second, and use only whole seconds. The default value if unspecified is 6 digits after the decimal separator.
So an unspecified value would store a date like:
TIMESTAMP 24-JAN-2012 08.00.05.993847 AM
And specifying (0)
stores only:
TIMESTAMP(0) 24-JAN-2012 08.00.05 AM
No reason but indifference, I'd guess.
Such query strings are usually generated by a graphical query tool. The user joins a few tables, adds a filter, a sort order, and tests the results. Since the user may want to save the query as a view, the tool adds a TOP 100 PERCENT. In this case, though, the user copies the SQL into his code, parameterized the WHERE clause, and hides everything in a data access layer. Out of mind, out of sight.
You need a loop over the lines of a file, you need to learn about string methods
with open(filename,'r') as f:
for line in f.readlines():
# python can do regexes, but this is for s fixed string only
if "something" in line:
idx1 = line.find('"')
idx2 = line.find('"', idx1+1)
field = line[idx1+1:idx2-1]
print(field)
and you need a method to pass the filename to your python program and while you are at it, maybe also the string to search for...
For the future, try to ask more focused questions if you can,
I need more information really but it will be along the lines of..
SELECT table1.*, table2.col1, table2.col3 FROM table1 JOIN table2 USING(id)
I will assume that you've done a data dump as insert statements, and you (or whoever Googles this) are attempting to figure out the date and time, or translate it for use elsewhere (eg: to convert to MySQL inserts). This is actually easy in any programming language.
Let's work with this:
CAST(0x0000A61300B1F1EB AS DateTime)
This Hex representation is actually two separate data elements... Date and Time. The first four bytes are date, the second four bytes are time.
Convert both of the segments to integers using the programming language of your choice (it's a direct hex to integer conversion, which is supported in every modern programming language, so, I will not waste space with code that may or may not be the programming language you're working in).
Now, what to do with those integers:
Date
Date is since 01/01/1900, and is represented as days. So, add 42,515 days to 01/01/1900, and your result is 05/27/2016.
Time
Time is a little more complex. Take that INT and do the following to get your time in microseconds since midnight (pseudocode):
TimeINT=Hex2Int(HexTime)
MicrosecondsTime = TimeINT*10000/3
From there, use your language's favorite function calls to translate microseconds (38872676666.7 µs in the example above) into time.
The result would be 10:47:52.677
Go to Window → Preferences → Java → Installed JREs. Select the JRE you're using, click Edit, and there will be a line for Default VM Arguments which will apply to every execution. For instance, I use this on OS X to hide the icon from the dock, increase max memory and turn on assertions:
-Xmx512m -ea -Djava.awt.headless=true
ng --version

In case your git-bash
's PATH
presents but not latest and you don't want a reboot but regenerate your PATH
s, you can try the following:
cmd.exe
, powershell.exe
, and git-bash.exe
and reopen one cmd.exe window from the Start Menu or Desktop context.PATH
, you may also need to open one privileged cmd window.PATH
env is updated. Please note that the terminal in IntelliJ IDEA is probably a login shell or some other kind of magic, so PATH
in it may won't change until you restart IDEA.Windows Explorer
process as well and retry the steps above.Note: This doesn't work with all Windows versions, and open cmd.exe
anywhere other than the Start Menu or Desktop context menu may not work, tested with my 4 computers and 3 of them works. I didn't figure out why this works, but since the PATH
environment variable is generated automatically when I login and logout, I'd not to mess up that variable with variable concatenation.
If ruby was installed in the following way:
./configure --prefix=/usr/local
make
sudo make install
You can uninstall it in the following way:
Check installed ruby version; lets assume 2.1.2
wget http://cache.ruby-lang.org/pub/ruby/2.1/ruby-2.1.2.tar.bz2
bunzip ...
tar xfv ...
cd ruby-2.1.2
./configure --prefix=/usr/local
make
sudo checkinstall
# will build deb or rpm package and try to install it
After installation, you can now remove the package and it will remove the directories/files/etc.
sudo rpm -e ruby # or dpkg -P ruby (for Debian-like systems)
There might be some artifacts left:

Use -Xms1024m -Xmx1024m to control your heap size (1024m is only for demonstration, the exact number depends your system memory). Setting minimum and maximum heap size to the same is usually a best practice since JVM doesn't have to increase heap size at runtime.

git ls-tree --full-tree -r HEAD
and git ls-files
return all files at once. For a large project with hundreds or thousands of files, and if you are interested in a particular file/directory, you may find more convenient to explore specific directories. You can do it by obtaining the ID/SHA-1 of the directory that you want to explore and then use git cat-file -p [ID/SHA-1 of directory]
. For example:
git cat-file -p 14032aabd85b43a058cfc7025dd4fa9dd325ea97
100644 blob b93a4953fff68df523aa7656497ee339d6026d64 glyphicons-halflings-regular.eot

100644 blob 9e612858f802245ddcbf59788a0db942224bab35 glyphicons-halflings-regular.woff
100644 blob 64539b54c3751a6d9adb44c8e3a45ba5a73b77f0 glyphicons-halflings-regular.woff2
In the example above, 14032aabd85b43a058cfc7025dd4fa9dd325ea97
is the ID/SHA-1 of the directory that I wanted to explore. In this case, the result was that four files within that directory were being tracked by my Git repo. If the directory had additional files, it would mean those extra files were not being tracked. You can add files using git add <file>...
of course.
You'd want the COUNT
operator.
SELECT NUMBER, COUNT(*)

I was unable to use the JSONConvert method suggested by xhafan
In .Net 4.5 even after adding the "System.Web.Extensions" assembly reference I was still unable to access the JSONConvert.
However, once you add the reference you can get the same string print out using:
JavaScriptSerializer js = new JavaScriptSerializer();
string jsonstring = js.Serialize(yourClassObject);
You have misunderstood the Python list
object. It is similar to a C pointer-array
. It does not actually "copy" the object which you append to it. Instead, it just store a "pointer" to that object.
Try the following code:
>>> d={}
>>> dlist=[]
>>> for i in xrange(0,3):
d['data']=i
dlist.append(d)
print(d)
{'data': 0}
{'data': 1}
{'data': 2}
>>> print(dlist)
[{'data': 2}, {'data': 2}, {'data': 2}]
So why is print(dlist)
not the same as print(d)
?
The following code shows you the reason:
>>> for i in dlist:
print "the list item point to object:", id(i)
the list item point to object: 47472232
the list item point to object: 47472232
the list item point to object: 47472232
So you can see all the items in the dlist
is actually pointing to the same dict
object.
The real answer to this question will be to append the "copy" of the target item, by using d.copy()
.
>>> dlist=[]
>>> for i in xrange(0,3):
d['data']=i
dlist.append(d.copy())
print(d)
{'data': 0}
{'data': 1}
{'data': 2}
>>> print dlist
[{'data': 0}, {'data': 1}, {'data': 2}]
Try the id()
trick, you can see the list items actually point to completely different objects.
>>> for i in dlist:
print "the list item points to object:", id(i)
the list item points to object: 33861576
the list item points to object: 47472520
the list item points to object: 47458120
Ignoring checking is a bad idea as it makes you susceptible to Man-in-the-middle attacks.
I took the freedom to improve nikobelia's answer by only adding each machine's key once and actually setting ok/changed status in Ansible:
- name: Accept EC2 SSH host keys
connection: local
become: false
shell: |
ssh-keygen -F {{ inventory_hostname }} ||
ssh-keyscan -H {{ inventory_hostname }} >> ~/.ssh/known_hosts
register: known_hosts_script
changed_when: "'found' not in known_hosts_script.stdout"
However, Ansible starts gathering facts before the script runs, which requires an SSH connection, so we have to either disable this task or manually move it to later:
- name: Example play
hosts: all
gather_facts: no # gather facts AFTER the host key has been accepted instead
tasks:
# https://stackoverflow.com/questions/32297456/
- name: Accept EC2 SSH host keys
connection: local
become: false
shell: |
ssh-keygen -F {{ inventory_hostname }} ||
ssh-keyscan -H {{ inventory_hostname }} >> ~/.ssh/known_hosts
register: known_hosts_script
changed_when: "'found' not in known_hosts_script.stdout"
- name: Gathering Facts
setup:
One kink I haven't been able to work out is that it marks all as changed even if it only adds a single key. If anyone could contribute a fix that would be great!

If you are looking for row count of all tables in all databases (which was what I was looking for) then I found this combination of this and this to work. No idea whether it is optimal or not:
SET NOCOUNT ON
DECLARE @AllTables table (DbName sysname,SchemaName sysname, TableName sysname, RowsCount int )
DECLARE
@SQL nvarchar(4000)
SET @SQL='SELECT ''?'' AS DbName, s.name AS SchemaName, t.name AS TableName, p.rows AS RowsCount FROM [?].sys.tables t INNER JOIN sys.schemas s ON t.schema_id=s.schema_id INNER JOIN [?].sys.partitions p ON p.OBJECT_ID = t.OBJECT_ID'
INSERT INTO @AllTables (DbName, SchemaName, TableName, RowsCount)
EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT DbName, SchemaName, TableName, SUM(RowsCount), MIN(RowsCount), SUM(1)
FROM @AllTables
WHERE RowsCount > 0
GROUP BY DbName, SchemaName, TableName
ORDER BY DbName, SchemaName, TableName
Yes, there is a split
command. It will split a file by lines or bytes.
$ split --help
Usage: split [OPTION]... [INPUT [PREFIX]]
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default
size is 1000 lines, and default PREFIX is `x'. With no INPUT, or when INPUT
is -, read standard input.
Mandatory arguments to long options are mandatory for short options too.
-a, --suffix-length=N use suffixes of length N (default 2)
-b, --bytes=SIZE put SIZE bytes per output file
-C, --line-bytes=SIZE put at most SIZE bytes of lines per output file
-d, --numeric-suffixes use numeric suffixes instead of alphabetic
-l, --lines=NUMBER put NUMBER lines per output file
--verbose print a diagnostic just before each
output file is opened
--help display this help and exit
--version output version information and exit
SIZE may have a multiplier suffix:
b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024,
GB 1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y.
Updated answer:
The problem with my original answer, as pointed out in the comments by @jpm, is the behavior at the boundaries. Python 3 makes this even more difficult since it uses "bankers" rounding instead of "old school" rounding. However, in looking into this issue I discovered an even better solution using the decimal
library.
import decimal
def round_up(x, place=0):
context = decimal.getcontext()
# get the original setting so we can put it back when we're done
original_rounding = context.rounding
# change context to act like ceil()
context.rounding = decimal.ROUND_CEILING
rounded = round(decimal.Decimal(str(x)), place)
context.rounding = original_rounding
return float(rounded)
Or if you really just want a one-liner:
import decimal
decimal.getcontext().rounding = decimal.ROUND_CEILING
# here's the one-liner
float(round(decimal.Decimal(str(0.1111)), ndigits=2))
>> 0.12
# Note: this only affects the rounding of `Decimal`
round(0.1111, ndigits=2)
>> 0.11
Here are some examples:
round_up(0.022499999999999999, 2)
>> 0.03
round_up(0.1111111111111000, 2)
>> 0.12
round_up(0.1111111111111000, 3)
>> 0.112
round_up(3.4)
>> 4.0
# @jpm - boundaries do what we want
round_up(0.1, 2)
>> 0.1
round_up(1.1, 2)
>> 1.1
# Note: this still rounds toward `inf`, not "away from zero"
round_up(2.049, 2)
>> 2.05
round_up(-2.0449, 2)
>> -2.04
We can use it to round to the left of the decimal as well:
round_up(11, -1)
>> 20
We don't multiply by 10, thereby avoiding the overflow mentioned in this answer.
round_up(1.01e308, -307)
>> 1.1e+308
Original Answer (Not recommended):
This depends on the behavior you want when considering positive and negative numbers, but if you want something that always rounds to a larger value (e.g. 2.0449 -> 2.05, -2.0449 -> -2.04) then you can do:
round(x + 0.005, 2)
or a little fancier:
def round_up(x, place):
return round(x + 5 * 10**(-1 * (place + 1)), place)
This also seems to work as follows:
round(144, -1)
# 140
round_up(144, -1)
# 150
round_up(1e308, -307)
# 1.1e308
Just Specify the Frame of the View, where you want to show the gradient color.
let firstColor = UIColor(red: 69/255, green: 90/255, blue: 195/255, alpha: 1.0).CGColor
let secondColor = UIColor(red: 230/255, green: 44/255, blue: 75/255, alpha: 1.0).CGColor
let gradientLayer = CAGradientLayer()
gradientLayer.colors = [ firstColor, secondColor]
gradientLayer.locations = [ 0.0, 1.0]
gradientLayer.frame = CGRectMake(0, 0, 375, 64)// You can mention frame here
self.view.layer.addSublayer(gradientLayer)
On OS X or macOS using Homebrew to install and upgrade Python3 I had to delete symbolic links before python -m venv --upgrade ENV_DIR
would work.
I saved the following in upgrade_python3.sh so I would remember how months from now when I need to do it again:
brew upgrade python3
find ~/.virtualenvs/ -type l -delete
find ~/.virtualenvs/ -type d -mindepth 1 -maxdepth 1 -exec python3 -m venv --upgrade "{}" \;
UPDATE: while this seemed to work well at first, when I ran py.test it gave an error. In the end I just re-created the environment from a requirements file.
Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:
The second example would be the one to go with, not just for readability, but because of the fact that in the first example, If NOT value1 would return a boolean value to be compared against value2. IOW, you need to rewrite that example as
If NOT (value1 = value2)
which just makes the use of the NOT keyword pointless.
The error means the OS of the listening socket recognized the inbound connection request but chose to intentionally reject it.
Assuming an intermediate firewall is not getting in the way, there are only two reasons (that I know of) for the OS to reject an inbound connection request. One reason has already been mentioned several times - the listening port being connected to is not open.
There is another reason that has not been mentioned yet - the listening port is actually open and actively being used, but its backlog of queued inbound connection requests has reached its maximum so there is no room available for the inbound connection request to be queued at that moment. The server code has not called accept() enough times yet to finish clearing out available slots for new queue items.
Wait a moment or so and try the connection again. Unfortunately, there is no way to differentiate between "the port is not open at all" and "the port is open but too busy right now". They both use the same generic error code.

For some reason the file you are writing to cannot be created or overwritten.
The reason could be that you do not have permission to write in the directory
or the file name is not valid.
Vim has a builtin help system. I just quoted what it says to :h E212
.
You might want to edit the file as a superuser as sudo vim FILE
. Or if you don't want to leave your existing vim session (and now have proper sudo rights), you can issue:
:w !sudo tee % > /dev/null
Which will save the file.

You can use SQLite's function creation routines (PHP manual):
$db_obj->sqliteCreateFunction('Encrypt', 'MyEncryptFunction', 2);
$db_obj->sqliteCreateFunction('Decrypt', 'MyDecryptFunction', 2);
When inserting data, you can use the encryption function directly and INSERT the encrypted data or you can use the custom function and pass unencrypted data:
$insert_obj = $db_obj->prepare('INSERT INTO table (Clear, Encrypted) ' .
'VALUES (:clear, Encrypt(:data, "' . $passwordhash_str . '"))');
When retrieving data, you can also use SQL search functionality:
$select_obj = $db_obj->prepare('SELECT Clear, ' .
'Decrypt(Encrypted, "' . $passwordhash_str . '") AS PlainText FROM table ' .
'WHERE PlainText LIKE :searchterm');
find -execdir rename
This renames files and directories with a regular expression affecting only basenames.
So for a prefix you could do:
PATH=/usr/bin find . -depth -execdir rename 's/^/Unix_/' '{}' \;
or to affect files only:
PATH=/usr/bin find . -type f -execdir rename 's/^/Unix_/' '{}' \;
-execdir
first cd
s into the directory before executing only on the basename.

Select's default value should be one of its value in the list. In order to load the select with default value you can use ng-options. A scope variable need to be set in the controller and that variable is assigned as ng-model in HTML's select tag.

If you try to console log query object directly you will get error TypeError: Cannot convert object to primitive value
So I would suggest use JSON.stringify
const http = require('http');
const url = require('url');
const server = http.createServer((req, res) => {
const parsedUrl = url.parse(req.url, true);
const path = parsedUrl.pathname, query = parsedUrl.query;
const method = req.method;
res.end("hello world\n");
console.log(`Request received on: ${path} + method: ${method} + query:
${JSON.stringify(query)}`);
console.log('query: ', query);
});
server.listen(3000, () => console.log("Server running at port 3000"));
So doing curl http://localhost:3000/foo\?fizz\=buzz
will return Request received on: /foo + method: GET + query: {"fizz":"buzz"}
If you just deserialize to dynamic you will get a JObject back. You can get what you want by using an ExpandoObject.
var converter = new ExpandoObjectConverter();
dynamic message = JsonConvert.DeserializeObject<ExpandoObject>(jsonString, converter);
If I understood OP correctly, we want to enforce a contract where GraphicsDeviceManager is always initialised by implementing classes. I had a similar problem and I was looking for a better solution, but this is the best I can think of:
Add a SetGraphicsDeviceManager(GraphicsDeviceManager gdo) to the interface, and that way the implementing classes will be forced to write a logic which will be require a call from constructor.
Use services.msc or (Start > Control Panel > Administrative Tools > Services) to find the service in question. Double-click to see the service name and the path to the executable.
Check the exe version information for a clue as to the owner of the service, and use Add/Remove programs to do a clean uninstall if possible.
Failing that, from the command prompt:
sc stop servicexyz
sc delete servicexyz
No restart should be required.
The font may exist with different names, and not at all on some systems, so you need to use different variations and fallback to get the closest possible look on all systems:
font-family: "Comic Sans MS", "Comic Sans", cursive;
Be careful what you use this font for, though. Many consider it as ugly and overused, so it should not be use for something that should look professional.
Federico Zancan's answer is correct but you don't have to give your script an ID and eval all your script. Just eval your function name and it can be called.
To achieve this in our project, we wrote a proxy function to call the function returned inside the Ajax response.
function FunctionProxy(functionName){
var func = eval(functionName);
func();
}

Set setHasMenuOptions(true) works if application has a theme with Actionbar such as Theme.MaterialComponents.DayNight.DarkActionBar
or Activity
has it's own Toolbar, otherwise onCreateOptionsMenu
in fragment does not get called.
If you want to use standalone Toolbar
you either need to get activity and set your Toolbar
as support action bar with
(requireActivity() as? MainActivity)?.setSupportActionBar(toolbar)
which lets your fragment onCreateOptionsMenu to be called.
Other alternative is, you can inflate your Toolbar
's own menu with toolbar.inflateMenu(R.menu.YOUR_MENU)
and item listener with
toolbar.setOnMenuItemClickListener {
// do something
true
}
It varies based on the options that you pass to install
and the contents of the distutils configuration files on the system/in the package. I don't believe that any files are modified outside of directories specified in these ways.
Notably, distutils does not have an uninstall command at this time.
It's also noteworthy that deleting a package/egg can cause dependency issues – utilities like easy_install
attempt to alleviate such problems.
You just missed an initialization step I think.
You can see what fonts you have available with the command windowsFonts()
. For example mine looks like this when I started looking at this:
> windowsFonts()
$serif
[1] "TT Times New Roman"
$sans
[1] "TT Arial"
$mono
[1] "TT Courier New"
After intalling the package extraFont and running font_import
like this (it took like 5 minutes):
library(extrafont)
font_import()
loadfonts(device = "win")
I had many more available - arguable too many, certainly too many to list here.
Then I tried your code:
library(ggplot2)
library(extrafont)
loadfonts(device = "win")
a <- ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
ggtitle("Fuel Efficiency of 32 Cars") +
xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
theme(text=element_text(size=16, family="Comic Sans MS"))
print(a)
yielding this:
You can find the name of a font you need for the family
parameter of element_text
with the following code snippet:
> names(wf[wf=="TT Times New Roman"])
[1] "serif"
And then:
library(ggplot2)
library(extrafont)
loadfonts(device = "win")
a <- ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
ggtitle("Fuel Efficiency of 32 Cars") +
xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
theme(text=element_text(size=16, family="serif"))
print(a)

Operators like <=
in Python are generally not overriden to mean something significantly different than "less than or equal to". It's unusual for the standard library does this--it smells like legacy API to me.
Use the equivalent and more clearly-named method, set.issubset
. Note that you don't need to convert the argument to a set; it'll do that for you if needed.
set(['a', 'b']).issubset(['a', 'b', 'c'])

You never created an instance.
You've defined average as an instance method, thus, in order to use average you need to create an instance first.
If you've decided that:
then I don't see the a taboo over synchronizezd(this).
Some people deliberately use synchronized(this) (instead of marking the method synchronized) inside the whole contents of a method because they think it's "clearer to the reader" which object is actually being synchronized on. So long as people are making an informed choice (e.g. understand that by doing so they're actually inserting extra bytecodes into the method and this could have a knock-on effect on potential optimisations), I don't particularly see a problem with this. You should always document the concurrent behaviour of your program, so I don't see the "'synchronized' publishes the behaviour" argument as being so compelling.
As to the question of which object's lock you should use, I think there's nothing wrong with synchronizing on the current object if this would be expected by the logic of what you're doing and how your class would typically be used. For example, with a collection, the object that you would logically expect to lock is generally the collection itself.
Different tools may interpret the meaning of @Nullable
differently. For example, the Checker Framework and FindBugs handle @Nullable
differently.
Since MongoDB version 3.2 you can use updateMany():

To answer your comment to Alex. Here's quick code that should allow you to get the fields like activity_details, last_name, etc. from the json dictionary that is returned:
NSDictionary *userinfo=[jsondic valueforKey:@"#data"];
NSDictionary *user;
NSInteger i = 0;
NSString *skey;
if(userinfo != nil){
for( i = 0; i < [userinfo count]; i++ ) {
if(i)
skey = [NSString stringWithFormat:@"%d",i];
else
skey = @"";
user = [userinfo objectForKey:skey];
NSLog(@"activity_details:%@",[user objectForKey:@"activity_details"]);
NSLog(@"last_name:%@",[user objectForKey:@"last_name"]);
NSLog(@"first_name:%@",[user objectForKey:@"first_name"]);
NSLog(@"photo_url:%@",[user objectForKey:@"photo_url"]);
}
}
Open the properties of the solution and click publish. Then, reclick application files. Change prerequisite to include.
Though asynchronous style may be the nature of node.js and generally you should not do this, there are some times you want to do this.
I'm writing a handy script to check an API and want not to mess it up with callbacks.
Javascript cannot execute synchronous requests, but C libraries can.
You can also use head
and tail
:
In [29]: pd.concat([df.head(1), df.tail(1)])
Out[29]:
a b
0 1 a
3 4 d
When you say
enum {RANDOM, IMMEDIATE, SEARCH} strategy;
you create a single instance variable, called 'strategy' of a nameless enum. This is not a very useful thing to do - you need a typedef:
typedef enum {RANDOM, IMMEDIATE, SEARCH} StrategyType;
StrategyType strategy = IMMEDIATE;
According to official documentation, the following command worked for me.

I was trying to run by "react-native run-android" command. make sure to have react-native cli installed globally!
(From Microsoft SQL Server Book Online)
UNION [ALL]
Specifies that multiple result sets are to be combined and returned as a single result set.
ALL
Incorporates all rows into the results. This includes duplicates. If not specified, duplicate rows are removed.
UNION
will take too long as a duplicate rows finding like DISTINCT
is applied on the results.
SELECT * FROM Table1
UNION
SELECT * FROM Table2
is equivalent of:
SELECT DISTINCT * FROM (
SELECT * FROM Table1
UNION ALL
SELECT * FROM Table2) DT
A side effect of applying
DISTINCT
over results is a sorting operation on results.
UNION ALL
results will be shown as arbitrary order on results But UNION
results will be shown as ORDER BY 1, 2, 3, ..., n (n = column number of Tables)
applied on results. You can see this side effect when you don't have any duplicate row.
driver.findElement(By.id("invoice_supplier_id")).setAttribute("value", "your value");
You can solve this problem by using AJAX. You don't need to load JQuery for AJAX but it has a better error and success handling than native JS.
I would do it like so:
1) add an click eventlistener to all my anchors on the page. 2) on click, you can setup an ajax-request to your php, in the POST-DATA you set the anchor id or the text-value 3) the php gets the value and you can setup a request to your database. Then you return the value which you need and echo it to the ajax-request. 4) your success function of the ajax-request is doing some stuff
For more information about ajax-requests look back here:
-> Ajax-Request NATIVE https://blog.garstasio.com/you-dont-need-jquery/ajax/
A simple JQuery examle:
$("button").click(function(){
$.ajax({url: "demo_test.txt", success: function(result){
$("#div1").html(result);
}});
});
If you want to stick to an array then this way you can make use. But its not good as compared to List and not recommended. However it will solve your problem.
import java.util.Scanner;
public class ArrayModify {
public static void main(String[] args) {
int[] list;
String st;
String[] stNew;
Scanner scan = new Scanner(System.in);
System.out.println("Enter Numbers: "); // If user enters 5 6 7 8 9
st = scan.nextLine();
stNew = st.split("\\s+");
list = new int[stNew.length]; // Sets array size to 5
for (int i = 0; i < stNew.length; i++){
list[i] = Integer.parseInt(stNew[i]);
System.out.println("You Enterred: " + list[i]);
}
}
}
You can use ->child
to get a child element named child.
This element will contain the text of the child element.
But if you try var_dump()
on that variable, you will see it is not actually a PHP string.
The easiest way around this is to perform a strval(xml->child);
That will convert it to an actual PHP string.
This is useful when debugging when looping your XML and using var_dump()
to check the result.
So $s = strval($xml->child);
.
Use this both installation and then go ahead with your python code
pip install google-cloud
pip install google-cloud-vision

DateTime->now->strftime('%m/%d/%Y')

fun String?.longARGB(): String? {
if (this == null || !startsWith("#")) return null
// #RRGGBB or #AARRGGBB
if (length == 7 || length == 9) return this
// #RGB or #ARGB
if (length in 4..5) {
val rgb = "#${this[1]}${this[1]}${this[2]}${this[2]}${this[3]}${this[3]}"

Yes you can. In c++, class and struct are kind of similar. We can define not only structure inside a class, but also a class inside one. It is called inner class.
As an example I am adding a simple Trie class.
class Trie {
private:
struct node{
node* alp[26];
bool isend;
};
node* root;
node* createNode(){
node* newnode=new node();
for(int i=0; i<26; i++){
newnode->alp[i]=nullptr;
}
newnode->isend=false;
return newnode;
}
public:
/** Initialize your data structure here. */
Trie() {
root=createNode();
}
/** Inserts a word into the trie. */
void insert(string word) {
node* head=root;
for(int i=0; i<word.length(); i++){
if(head->alp[int(word[i]-'a')]==nullptr){
node* newnode=createNode();
head->alp[int(word[i]-'a')]=newnode;
}
head=head->alp[int(word[i]-'a')];
}
head->isend=true;
}
/** Returns if the word is in the trie. */
bool search(string word) {
node* head=root;
for(int i=0; i<word.length(); i++){
if(head->alp[int(word[i]-'a')]==nullptr){
return false;
}
head=head->alp[int(word[i]-'a')];
}
if(head->isend){return true;}
return false;
}
/** Returns if there is any word in the trie that starts with the given prefix. */
bool startsWith(string prefix) {
node* head=root;
for(int i=0; i<prefix.length(); i++){
if(head->alp[int(prefix[i]-'a')]==nullptr){
return false;
}
head=head->alp[int(prefix[i]-'a')];
}
return true;
}
};
/**
* Your Trie object will be instantiated and called as such:
* Trie* obj = new Trie();
* obj->insert(word);
* bool param_2 = obj->search(word);
* bool param_3 = obj->startsWith(prefix);
*/
$scope.rtGo = function(){

android:drawableLeft is always keeping android:paddingLeft as a distance from the left border. When the button is not set to android:width="wrap_content", it will always hang to the left!
With Android 4.0 (API level 14) you can use android:drawableStart attribute to place a drawable at the start of the text. The only backward compatible solution I've come up with is using an ImageSpan to create a Text+Image Spannable:
Button button = (Button) findViewById(R.id.button);
Spannable buttonLabel = new SpannableString(" Button Text");
buttonLabel.setSpan(new ImageSpan(getApplicationContext(), R.drawable.icon,
ImageSpan.ALIGN_BOTTOM), 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
button.setText(buttonLabel);
In my case I needed to also adjust the android:gravity attribute of the Button to make it look centered:
<Button
android:id="@+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minHeight="32dp"
android:minWidth="150dp"
android:gravity="center_horizontal|top" />
I encountered the same problem... I solved it by creating a custom axios instance. and using that to make a authenticated delete request..
const token = localStorage.getItem('token');
const request = axios.create({
headers: {
Authorization: token
}
});
await request.delete('<your route>, { data: { <your data> }});
Try to use (focus)
and (focusout)
instead of onfocus
and onfocusout
like this : -
<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">
also you can use like this :-
some people prefer the on- prefix alternative, known as the canonical form:
<input name="date" type="text" on-focus="focusFunction()" on-focusout="focusOutFunction()">
Know more about event binding see here.
you have to use HostListner for your use case
Angular will invoke the decorated method when the host element emits the specified event.
@HostListener
is a decorator for the callback/event handler method
See my Update working Plunker.
Working Example Working Stackblitz
Some other events can be used in angular -
(focus)="myMethod()"
(blur)="myMethod()"
(submit)="myMethod()"
(scroll)="myMethod()"
Rarely, a hardened HTTP server is configured to give no server information or misleading server information. In those scenarios if the server has PHP enabled you can add:
<?php phpinfo(); ?>
in a file and browse to it and look for the
_SERVER["SERVER_SOFTWARE"]
entry. This is susceptible to the same hardening lack of information/misleading though I would imagine that it's not altered often, because this method first requires access to the machine to create the PHP file.
Adding to @David Roussel answer, classes may be loaded by multiple class loaders.
Lets understand how class loader works.
From javin paul blog in javarevisited :
ClassLoader
follows three principles.
A class is loaded in Java, when its needed. Suppose you have an application specific class called Abc.class, first request of loading this class will come to Application ClassLoader which will delegate to its parent Extension ClassLoader which further delegates to Primordial or Bootstrap class loader
Bootstrap ClassLoader is responsible for loading standard JDK class files from rt.jar and it is parent of all class loaders in Java. Bootstrap class loader don't have any parents.
Extension ClassLoader delegates class loading request to its parent, Bootstrap and if unsuccessful, loads class form jre/lib/ext directory or any other directory pointed by java.ext.dirs system property
System or Application class loader and it is responsible for loading application specific classes from CLASSPATH environment variable, -classpath or -cp command line option, Class-Path attribute of Manifest file inside JAR.
Application class loader is a child of Extension ClassLoader and its implemented by sun.misc.Launcher$AppClassLoader
class.
NOTE: Except Bootstrap class loader, which is implemented in native language mostly in C, all Java class loaders are implemented using java.lang.ClassLoader
.
According to visibility principle, Child ClassLoader can see class loaded by Parent ClassLoader but vice-versa is not true.
According to this principle a class loaded by Parent should not be loaded by Child ClassLoader again
You can modify the whole InfoWindow using jquery alone...
var popup = new google.maps.InfoWindow({
content:'<p id="hook">Hello World!</p>'
});
Here the <p> element will act as a hook into the actual InfoWindow. Once the domready fires, the element will become active and accessible using javascript/jquery, like $('#hook').parent().parent().parent().parent()
.
The below code just sets a 2 pixel border around the InfoWindow.
google.maps.event.addListener(popup, 'domready', function() {
var l = $('#hook').parent().parent().parent().siblings();
for (var i = 0; i < l.length; i++) {
if($(l[i]).css('z-index') == 'auto') {
$(l[i]).css('border-radius', '16px 16px 16px 16px');
$(l[i]).css('border', '2px solid red');
}
}
});
You can do anything like setting a new CSS class or just adding a new element.
Play around with the elements to get what you need...
why don't u try using an absolute xPath
//soap:Envelope[1]/soap:Body[1]/PaymentNotification[1]/payment
or since u know that it is a payment and payment doesn't have any attributes just select directly from payment
//soap:Envelope[1]/soap:Body[1]/PaymentNotification[1]/payment/*
In CSS:
textarea {
border-style: none;
border-color: Transparent;
overflow: auto;
}
You can achieve the desired result by encapsulating the HTML code in a div tag which contains the "required' class followed by the "form-group" class. *however this works only if you have Bootstrap.
<div class="form-group required">
<div class="required">
<label>Name:</label>
<input type="text">
</div>
<div>
Right click the table design and go to Relationships and choose the foreign key on the left-side pane and in the right-side pane, set Enforce foreign key constraint to 'Yes' (to enable foreign key constraints) or 'No' (to disable it).
Here is the solution I could find:
#wrapper {
float:right;
position:relative;
left:-50%;
text-align:left;
}
#wrapper ul {
list-style:none;
position:relative;
left:50%;
}
#wrapper li{
float:left;
position:relative;
}
To update this ancient question for .NET 4, there is now a much neater way:
var lines = File.ReadAllLines(filename);
foreach (string line in lines)
{
Console.WriteLine(line);
}
git checkout -f
must work, if your previous state is clean.
For version 4.x you can now use the req.baseUrl
in addition to req.path
to get the full path. For example, the OP would now do something like:
//auth required or redirect
app.use('/account', function(req, res, next) {
console.log(req.baseUrl + req.path); // => /account
if(!req.session.user) {
res.redirect('/login?ref=' + encodeURIComponent(req.baseUrl + req.path)); // => /login?ref=%2Faccount
} else {
next();
}
});
If you want this to be handled by UILabel and not UITextView, you can make UILabel subclass, like this one:
class LinkedLabel: UILabel {
fileprivate let layoutManager = NSLayoutManager()
fileprivate let textContainer = NSTextContainer(size: CGSize.zero)
fileprivate var textStorage: NSTextStorage?
override init(frame aRect:CGRect){
super.init(frame: aRect)
self.initialize()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.initialize()
}
func initialize(){
let tap = UITapGestureRecognizer(target: self, action: #selector(LinkedLabel.handleTapOnLabel))
self.isUserInteractionEnabled = true
self.addGestureRecognizer(tap)
}
override var attributedText: NSAttributedString?{
didSet{
if let _attributedText = attributedText{
self.textStorage = NSTextStorage(attributedString: _attributedText)
self.layoutManager.addTextContainer(self.textContainer)
self.textStorage?.addLayoutManager(self.layoutManager)
self.textContainer.lineFragmentPadding = 0.0;
self.textContainer.lineBreakMode = self.lineBreakMode;
self.textContainer.maximumNumberOfLines = self.numberOfLines;
}
}
}
func handleTapOnLabel(tapGesture:UITapGestureRecognizer){
let locationOfTouchInLabel = tapGesture.location(in: tapGesture.view)
let labelSize = tapGesture.view?.bounds.size
let textBoundingBox = self.layoutManager.usedRect(for: self.textContainer)
let textContainerOffset = CGPoint(x: ((labelSize?.width)! - textBoundingBox.size.width) * 0.5 - textBoundingBox.origin.x, y: ((labelSize?.height)! - textBoundingBox.size.height) * 0.5 - textBoundingBox.origin.y)
let locationOfTouchInTextContainer = CGPoint(x: locationOfTouchInLabel.x - textContainerOffset.x, y: locationOfTouchInLabel.y - textContainerOffset.y)
let indexOfCharacter = self.layoutManager.characterIndex(for: locationOfTouchInTextContainer, in: self.textContainer, fractionOfDistanceBetweenInsertionPoints: nil)
self.attributedText?.enumerateAttribute(NSLinkAttributeName, in: NSMakeRange(0, (self.attributedText?.length)!), options: NSAttributedString.EnumerationOptions(rawValue: UInt(0)), using:{
(attrs: Any?, range: NSRange, stop: UnsafeMutablePointer<ObjCBool>) in
if NSLocationInRange(indexOfCharacter, range){
if let _attrs = attrs{
UIApplication.shared.openURL(URL(string: _attrs as! String)!)
}
}
})
}}
This class was made by reusing code from this answer. In order to make attributed strings check out this answer. And here you can find how to make phone urls.
I have a similar solution to @Satheesh using React hooks:
State initialization:
const [enteredText, setEnteredText] = useState('');
Input tag:
<input type="text" value={enteredText} (event handler, classNames, etc.) />
Inside the event handler function, after updating the object with data from input form, call:
setEnteredText('');
Note: This is described as 'two-way binding'
