for me this works

unicode(data).encode('utf-8')

Unless you have some really compelling reason not to, I suggest ditching the MS JDBC driver.

Instead, use the jtds jdbc driver. Read the README.SSO file in the jtds distribution on how to configure for single-sign-on (native authentication) and where to put the native DLL to ensure it can be loaded by the JVM.

In my case I resolved that problem using such approach:

1. Set new environment variable: JAVA_TOOL_OPTIONS = -Dfile.encoding=UTF8
2. Or set MAVEN_OPTS= -Dfile.encoding=UTF-8

Dont forget to add this code in your MainActivity.java:

MainActivity.java

mShaker = new ShakeListener(this);
mShaker.setOnShakeListener(new ShakeListener.OnShakeListener () {
    public void onShake() {
        Toast.makeText(MainActivity.this, "Shake " , Toast.LENGTH_LONG).show();        
    }
});

@Override
protected void onResume() {
    super.onResume();
    mShaker.resume();
}

@Override
protected void onPause() {
    super.onPause();
    mShaker.pause();
}

Or I give you a link about this stuff.

write() only takes a single string argument, so you could do this:

outf.write(str(num))

or

outf.write('{}'.format(num))  # more "modern"
outf.write('%d' % num)        # deprecated mostly

Also note that write will not append a newline to your output so if you need it you'll have to supply it yourself.

Aside:

Using string formatting would give you more control over your output, so for instance you could write (both of these are equivalent):

num = 7
outf.write('{:03d}\n'.format(num))

num = 12
outf.write('%03d\n' % num)          

to get three spaces, with leading zeros for your integer value followed by a newline:

007
012

format() will be around for a long while, so it's worth learning/knowing.

I had the same error message (in my case : "Argument 'languageSelectorCtrl' is not a function, got undefined").

After some tedious comparison with Angular seed's code, I found out that I had previously removed a reference to the controllers module in app.js. (spot it at https://github.com/angular/angular-seed/blob/master/app/js/app.js)

So I had this:

angular.module('MyApp', ['MyApp.filters', 'MyApp.services', 'MyApp.directives'])

This failed.

And when I added the missing reference:

angular.module('MyApp', ['MyApp.filters', 'MyApp.services', 'MyApp.controllers', 'MyApp.directives'])

The error message disappeared and Angular could instanciate the controllers again.

In makefile language $@ means "name of the target", so rm -f $@ translates to rm -f clean.

You need to specify to rm what exactly you want to delete, like rm -f *.o code1 code2

NSMutableAttributedString *text = [self.myUILabel.attributedText mutableCopy];
[text addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:NSMakeRange(0, text.length)];
self.myUILabel.attributedText = text;

The Correct Way from Sam Quest's answer only works if the first date is earlier than the second. Moreover, it will return 1 if the two dates are within a single day.

This is the solution that worked best for me. Just like most other solutions, it would still show incorrect results on two days in a year because of wrong day light saving offset.

private final static long MILLISECS_PER_DAY = 24 * 60 * 60 * 1000;

long calculateDeltaInDays(Calendar a, Calendar b) {

    // Optional: avoid cloning objects if it is the same day
    if(a.get(Calendar.ERA) == b.get(Calendar.ERA) 
            && a.get(Calendar.YEAR) == b.get(Calendar.YEAR)
            && a.get(Calendar.DAY_OF_YEAR) == b.get(Calendar.DAY_OF_YEAR)) {
        return 0;
    }
    Calendar a2 = (Calendar) a.clone();
    Calendar b2 = (Calendar) b.clone();
    a2.set(Calendar.HOUR_OF_DAY, 0);
    a2.set(Calendar.MINUTE, 0);
    a2.set(Calendar.SECOND, 0);
    a2.set(Calendar.MILLISECOND, 0);
    b2.set(Calendar.HOUR_OF_DAY, 0);
    b2.set(Calendar.MINUTE, 0);
    b2.set(Calendar.SECOND, 0);
    b2.set(Calendar.MILLISECOND, 0);
    long diff = a2.getTimeInMillis() - b2.getTimeInMillis();
    long days = diff / MILLISECS_PER_DAY;
    return Math.abs(days);
}

I've gotten the following to work:

html {
  background:
      linear-gradient(rgba(0,184,255,0.45),rgba(0,184,255,0.45)),
      url('bgimage.jpg') no-repeat center center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

The above will produce a nice opaque blue overlay.

The original variables you listed can be declared and assigned to the same value in a short line of code using destructuring assignment. The keywords let, const, and var can all be used for this type of assignment.

let [moveUp, moveDown, moveLeft, moveRight, mouseDown, touchDown] = Array(6).fill(false);

VBA has a CurDir keyword that will return the "current directory" as stored in Excel. I'm not sure all the things that affect the current directory, but definitely opening or saving a workbook will change it.

MyWorkbook.SaveAs CurDir & Application.PathSeparator & "MySavedWorkbook.xls"

This assumes that the sheet you want to save has never been saved and you want to define the file name in code.

More generic way in case qs has more than one dictionaries:

[int(v) for lst in qs for k, v in lst.items()]

--

>>> qs = [{u'a': 15L, u'b': 9L, u'a': 16L}, {u'a': 20, u'b': 35}]
>>> result_list = [int(v) for lst in qs for k, v in lst.items()]
>>> result_list
[16, 9, 20, 35]

This is simple css for Sign Mark.

ul li:after{opacity: 1;content: '\2713';right: 20px;position: absolute;font-size: 20px;font-weight: bold;}

I got this error when stubbing with sinon.

The fix is to use npm package sinon-as-promised when resolving or rejecting promises with stubs.

Instead of ...

sinon.stub(Database, 'connect').returns(Promise.reject( Error('oops') ))

Use ...

require('sinon-as-promised');
sinon.stub(Database, 'connect').rejects(Error('oops'));

There is also a resolves method (note the s on the end).

See http://clarkdave.net/2016/09/node-v6-6-and-asynchronously-handled-promise-rejections

I tried all the above methods and I did not get the value properly in the same format, then I found this.

$("#datetimepicker1").find("input")[1].value;

The above code will return the value in the same format as in the datetime picker.

This may help you guys in the future.

Hope this was helpful..

I can't reproduce this issue in a simple .NET 4.0 console application:

static class Program
{
    static void Main(string[] args)
    {
        var myDict = new Dictionary<string, string>
        {
            { "key1", "value1" },
            { "key2", "value2" }
        };

        Console.ReadKey();
    }
}

Can you try to reproduce it in a simple Console application and go from there? It seems likely that you're targeting .NET 2.0 (which doesn't support it) or client profile framework, rather than a version of .NET that supports initialization syntax.

"ABCDEFG".First returns "A"

Dim s as string

s = "Rajan"
s.First

s = "Sajan"
s.First

Great answer by F.Mörk. But if you want to update translation, or add new languages once the application is released, you're stuck, because you always have to recompile it to generate the resources.dll.

Here is a solution to manually compile a resource dll. It uses the resgen.exe and al.exe tools (installed with the sdk).

Say you have a Strings.fr.resx resource file, you can compile a resources dll with the following batch:

resgen.exe /compile Strings.fr.resx,WpfRibbonApplication1.Strings.fr.resources 
Al.exe /t:lib /embed:WpfRibbonApplication1.Strings.fr.resources /culture:"fr" /out:"WpfRibbonApplication1.resources.dll"
del WpfRibbonApplication1.Strings.fr.resources
pause

Be sure to keep the original namespace in the file names (here "WpfRibbonApplication1")

To make PasswordChar use the ? character instead:

passwordTextBox.PasswordChar = '\u25CF';

If you are getting this error, it could be because you don't have a route defined for your get.

For example:

const express = require('express');

const app = express();

app.get('/people', function (req, res) {
    res.send('hello');
})

app.listen(3000);


http://http://localhost:3000/people --> this works
http://http://localhost:3000 --> this will output Cannot GET / message.

Yeah, it's pretty simple:

input[type="submit"]{
  background: #fff;
  border: 1px solid #000;
  text-shadow: 1px 1px 1px #000;
}

I recommend giving it an ID or a class so that you can target it more easily.

eval() can not handle the list object

tf.reset_default_graph()

a = tf.Variable(0.2, name="a")
b = tf.Variable(0.3, name="b")
z = tf.constant(0.0, name="z0")
for i in range(100):
    z = a * tf.cos(z + i) + z * tf.sin(b - i)
grad = tf.gradients(z, [a, b])

init = tf.global_variables_initializer()

with tf.Session() as sess:
    init.run()
    print("z:", z.eval())
    print("grad", grad.eval())

but Session.run() can

print("grad", sess.run(grad))

correct me if I am wrong

Check this:

hello.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View paramView) {
        text.setText("hello");
    }
});

In navigateExtra we can pass only some specific name as argument otherwise it showing error like below: For Ex- Here I want to pass customer key in router navigate and I pass like this-

this.Router.navigate(['componentname'],{cuskey: {customerkey:response.key}});

but it showing some error like below:

Argument of type '{ cuskey: { customerkey: any; }; }' is not assignable to parameter of type 'NavigationExtras'.
  Object literal may only specify known properties, and 'cuskey' does not exist in type 'NavigationExt## Heading ##ras'

.

Solution: we have to write like this:

this.Router.navigate(['componentname'],{state: {customerkey:response.key}});

You should check that what you are passing to foreach is an array by using the is_array function

If you are not sure it's going to be an array you can always check using the following PHP example code:

if (is_array($variable)) {

  foreach ($variable as $item) {
   //do something
  }
}

This is a simple example and try to combine it with yours using some modifications. I prefer you set all the images in one array in order to make your code easier to read and shorter:

var myImage = document.getElementById("mainImage");

var imageArray = ["_images/image1.jpg","_images/image2.jpg","_images/image3.jpg",
  "_images/image4.jpg","_images/image5.jpg","_images/image6.jpg"];

var imageIndex = 0; 

function changeImage() {
  myImage.setAttribute("src",imageArray[imageIndex]);
  imageIndex = (imageIndex + 1) % imageArray.length;
}

setInterval(changeImage, 5000);

This will do it recursively for you:

find /path/to/base/dir/* -type d -ctime +10 -exec rm -rf {} \;

Explanation:

• find: the unix command for finding files / directories / links etc.
• /path/to/base/dir: the directory to start your search in.
• -type d: only find directories
• -ctime +10: only consider the ones with modification time older than 10 days
• -exec ... \;: for each such result found, do the following command in ...
• rm -rf {}: recursively force remove the directory; the {} part is where the find result gets substituted into from the previous part.

Alternatively, use:

find /path/to/base/dir/* -type d -ctime +10 | xargs rm -rf

Which is a bit more efficient, because it amounts to:

rm -rf dir1 dir2 dir3 ...

as opposed to:

rm -rf dir1; rm -rf dir2; rm -rf dir3; ...

as in the -exec method.

With modern versions of find, you can replace the ; with + and it will do the equivalent of the xargs call for you, passing as many files as will fit on each exec system call:

find . -type d -ctime +10 -exec rm -rf {} +

I got my code for the answer from a book called "C++ Programming In Easy Steps". The could below should work.

#include <fstream>
#include <string>
#include <iostream>

using namespace std;

int main()
{
    ofstream writer("filename.file-extension" , ios::app);

    if (!writer)
    {
        cout << "Error Opening File" << endl;
        return -1;
    }

    string info = "insert text here";
    writer.append(info);

    writer << info << endl;
    writer.close;
    return 0;   
} 

I hope this helps you.

One major point about Yield keyword is Lazy Execution. Now what I mean by Lazy Execution is to execute when needed. A better way to put it is by giving an example

Example: Not using Yield i.e. No Lazy Execution.

public static IEnumerable<int> CreateCollectionWithList()
{
    var list =  new List<int>();
    list.Add(10);
    list.Add(0);
    list.Add(1);
    list.Add(2);
    list.Add(20);

    return list;
}

Example: using Yield i.e. Lazy Execution.

public static IEnumerable<int> CreateCollectionWithYield()
{
    yield return 10;
    for (int i = 0; i < 3; i++) 
    {
        yield return i;
    }

    yield return 20;
}

Now when I call both methods.

var listItems = CreateCollectionWithList();
var yieldedItems = CreateCollectionWithYield();

you will notice listItems will have a 5 items inside it (hover your mouse on listItems while debugging). Whereas yieldItems will just have a reference to the method and not the items. That means it has not executed the process of getting items inside the method. A very efficient a way of getting data only when needed. Actual implementation of yield can seen in ORM like Entity Framework and NHibernate etc.

Depending on situation where you need this, maybe you can use anonymous functions like this:

$greet = function($name)
{
    echo('Hello ' . $name);
};

$greet('World');

...then you can set new function to the given variable any time

you can fix it with:

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>${servlet-api-version}</version>
    <scope>provided</scope>
</dependency>

provided solves this problem

This worked for me fine:

File 1:

    <html>
    <head></head>
    <body>
        <a href="#" onclick="window.open('file:///D:/Examples/file2.html'); return false">CLICK ME</a>
    </body>
    <footer></footer>
    </html>

File 2:

    <html>
        ...
    </html>

This method works regardless of whether or not the 2 files are in the same directory, BUT both files must be local.

For obvious security reasons, if File 1 is located on a remote server you absolutely cannot open a file on some client's host computer and trying to do so will open a blank target.

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

If you have 2 beans of the same class autowired to one class you shoud use @Qualifier (Spring Autowiring @Qualifier example).

But it seems like your problem comes from incorrect Java Syntax.

Your object should start with lower case letter

SuggestionService suggestion;

Your setter should start with lower case as well and object name should be with Upper case

public void setSuggestion(final Suggestion suggestion) {
    this.suggestion = suggestion;
}

Short answer is no.

XAMPP is normally built around a specific PHP version to ensure plugins and modules are all compatible and working correctly.

If your project specifically needs PHP 5.3 - the cleanest method is simply reinstalling an older version of XAMPP with PHP 5.3 packaged into it.

XAMPP 1.7.7 was their last update before moving off PHP 5.3.

I did it using Angular 2 Location since I didn't want to manipulate the global window object myself.

https://angular.io/docs/ts/latest/api/common/index/Location-class.html#!#prepareExternalUrl-anchor

It can be done like this:

import {Component} from '@angular/core';
import {Location} from '@angular/common';
@Component({selector: 'app-component'})
class AppCmp {
  constructor(location: Location) {
    location.go('/foo');
  }
}

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

I'm using XAMPP with Apache2.4, I had this same issue. I wanted to leave the default xampp/htdocs folder in place, be able to access it from locahost and have a Virtual Host to point to my dev area...

The full contents of my C:\xampp\apache\conf\extra\http-vhosts.conf file is below...

# Virtual Hosts
#
# Required modules: mod_log_config

# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs/2.4/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# Use name-based virtual hosting.
#

##NameVirtualHost *:80

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not

#
##<VirtualHost *:80>
    ##ServerAdmin [email protected]
    ##DocumentRoot "C:/xampp/htdocs/dummy-host.example.com"
    ##ServerName dummy-host.example.com

    <Directory "C:\nick\static">
        Allow from all
        Require all granted
    </Directory>
</VirtualHost>

I then updated my C:\windows\System32\drivers\etc\hosts file like this...

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#

# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.

#   ::1             localhost

127.0.0.1   dev.middleweek.co.uk
127.0.0.1       localhost

Restart your machine for good measure, open the XAMPP Control Panel and start Apache.

Now open your custom domain in your browser, in the above example, it'll be http://dev.middleweek.co.uk

Hope that helps someone!

And if you want to be able to view directory listings under your new Virtual host, then edit your VirtualHost block in C:\xampp\apache\conf\extra\http-vhosts.conf to include "Options Indexes" like this...

<VirtualHost *:80>
    DocumentRoot "C:\nick\static"
    ServerName dev.middleweek.co.uk
    <Directory "C:\nick\static">
        Allow from all
        Require all granted
        Options Indexes
    </Directory>
</VirtualHost>

Try this:

Calendar calendar = Calendar.getInstance();
calendar.setTime(yourdate);
int hours = calendar.get(Calendar.HOUR_OF_DAY);
int minutes = calendar.get(Calendar.MINUTE);
int seconds = calendar.get(Calendar.SECOND);

Edit:

hours, minutes, seconds

above will be the hours, minutes and seconds after converting yourdate to System Timezone!

If you're using a wrapper layer (like Kitchen CI) and you're running a 32b host, you'll have to preempt the installation of Vagrant boxes. Their default provider is the opscode "family" of binaries.

So before kitchen create default-ubuntu-1204 make sure you use:

vagrant box add default-ubuntu-1204 http://opscode-vm-bento.s3.amazonaws.com/vagrant/virtualbox/opscode_ubuntu-12.04-i386_chef-provisionerless.box

for using the 32b image if your host doesn't support word size virtualization

Depending on your version of postgresql you might run into a bug, that makes pg_stat_activity to omit active connections from dropped users. These connections are also not shown inside pgAdminIII.

If you are doing automatic testing (in which you also create users) this might be a probable scenario.

In this case you need to revert to queries like:

 SELECT pg_terminate_backend(procpid) 
 FROM pg_stat_get_activity(NULL::integer) 
 WHERE datid=(SELECT oid from pg_database where datname = 'your_database');

NOTE: In 9.2+ you'll have change procpid to pid.

No idea how you got your results, since it would not sort by string value... You should reverse a1 and a2 in your example

Best way in any case (as per Mladen) is:

metrics = {"sitea.com" => 745, "siteb.com" => 9, "sitec.com" => 10 }
metrics.sort_by {|_key, value| value}
  # ==> [["siteb.com", 9], ["sitec.com", 10], ["sitea.com", 745]]

If you need a hash as a result, you can use to_h (in Ruby 2.0+)

metrics.sort_by {|_key, value| value}.to_h
  # ==> {"siteb.com" => 9, "sitec.com" => 10, "sitea.com", 745}

The question is already answered, but you can resolve it like this:

File dependency.js

const doSomething = (x) => x
export default doSomething;

File myModule.js

import doSomething from "./dependency";

export default (x) => doSomething(x * 2);

File myModule.spec.js

jest.mock('../dependency');
import doSomething from "../dependency";
import myModule from "../myModule";

describe('myModule', () => {
  it('calls the dependency with double the input', () => {
    doSomething.mockImplementation((x) => x * 10)

    myModule(2);

    expect(doSomething).toHaveBeenCalledWith(4);
    console.log(myModule(2)) // 40
  });
});

Try:

With DependencedIncidents AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
),
lalala AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
)

And yes, you can reference common table expression inside common table expression definition. Even recursively. Which leads to some very neat tricks.

Something like this should work:

sh -c 'cd /tmp && exec pwd'

Declare the a element as display: inline-block and drop the width and height from the li element.

Alternatively, apply a float: left to the li element and use display: block on the a element. This is a bit more cross browser compatible, as display: inline-block is not supported in Firefox <= 2 for example.

The first method allows you to have a dynamically centered list if you give the ul element a width of 100% (so that it spans from left to right edge) and then apply text-align: center.

Use line-height to control the text's Y-position inside the element.

Because of the infinite superiority of Python over Java, Python has not one, but two toString operations.

One is __str__, the other is __repr__

__str__ will return a human readable string. __repr__ will return an internal representation.

__repr__ can be invoked on an object by calling repr(obj) or by using backticks `obj`.

When printing lists as well as other container classes, the contained elements will be printed using __repr__.

I guess the question arises, why would you need to do this? The reason for async in C# 5.0 is so you can await a result. This method is not actually asynchronous, but simply called at a time so as not to interfere too much with the current thread.

Perhaps it may be better to start a thread and leave it to finish on its own.

try this:

$("#mySelect1").find("option[text=" + text1 + "]").attr("selected", true);

As others have mentioned, try stopPropagation().

And there is a second handler to try: event.cancelBubble = true; It's a IE specific handler, but it is supported in at least FF. Don't really know much about it, as I haven't used it myself, but it might be worth a shot, if all else fails.

Had to look it up in the specs:

• Class.getResource(String resource)

• ClassLoader.getResource(String resource)

Class's getResource() - documentation states the difference:

This method delegates the call to its class loader, after making these changes to the resource name: if the resource name starts with "/", it is unchanged; otherwise, the package name is prepended to the resource name after converting "." to "/". If this object was loaded by the bootstrap loader, the call is delegated to ClassLoader.getSystemResource.

This isn't really recommended, but you can do it all inline like so:

<a href="#" onClick="function test(){ /* Do something */  } test(); return false;"></a>

But I can't think of any situations off hand where this would be better than writing the function somewhere else and invoking it onClick.

If you're on a shared hosting environment you won't have access to the php.ini to make these changes, if you need access, a virtual private server (VPS) or a dedicated server may be a better option if you're confident in managing it yourself.

Alternatively if you create a new file called .htaccess in your root of your web directory (Ensure it doesn't contain a .txt extension if using notepad to create the file) and copy something like this inside.

php_value settingToChange 6000

This will only work if your hosting provider let's you override the certain config value. Best to ask if it doesn't work after trying.

First of all print isn't a function in Python 2, it is a statement.

To suppress the automatic newline add a trailing ,(comma). Now a space will be used instead of a newline.

Demo:

print 1,
print 2

output:

1 2

Or use Python 3's print() function:

from __future__ import print_function
print(1, end=' ') # default value of `end` is '\n'
print(2)

As you can clearly see print() function is much more powerful as we can specify any string to be used as end rather a fixed space.

PHP uses weak typing (which it calls 'type juggling'), which is a bad idea (though that's a conversation for another time). When you try to use a variable in a context that requires a boolean, it will convert whatever your variable is into a boolean, according to some mostly arbitrary rules available here: http://www.php.net/manual/en/language.types.boolean.php#language.types.boolean.casting

the aim of balanced tree is to reach the leaf in a minimum of traversal (min height). The degree of the tree is the number of branches minus 1. A Balanced tree may be not Binary.

No. NodeJS is not available as an Apache module in the way mod-perl and mod-php are, so it's not possible to run node "on top of" Apache. As hexist pointed out, it's possible to run node as a separate process and arrange communication between the two, but this is quite different to the LAMP stack you're already using.

As a replacement for Apache, node offers performance advantages if you have many simultaneous connections. There's also a huge ecosystem of modules for almost anything you can think of.

From your question, it's not clear if you need to dynamically generate pages on every request, or just generate new content periodically for caching and serving. If its the latter, you could use separate node task to generate content to a directory that Apache would serve, but again, that's quite different to PHP or Perl.

Node isn't the best way to serve static content. Nginx and Varnish are more effective at that. They can serve static content while Node handles the dynamic data.

If you're considering using node for a web application at all, Express should be high on your list. You could implement a web application purely in Node, but Express (and similar frameworks like Flatiron, Derby and Meteor) are designed to take a lot of the pain and tedium away. Although the Express documentation can seem a bit sparse at first, check out the screen casts which are still available here: http://expressjs.com/2x/screencasts.html They'll give you a good sense of what express offers and why it is useful. The github repository for ExpressJS also contains many good examples for everything from authentication to organizing your app.

1. Use conditional formatting instead of VBA to highlight errors.

2. Using a VBA loop like the one you posted will take a long time to process

3. the statement If cell.Value = "#N/A" Then will never work. If you insist on using VBA to highlight errors, try this instead.

   Sub ColorCells()

   Dim Data As Range
   Dim cell As Range
   Set currentsheet = ActiveWorkbook.Sheets("Comparison")
   Set Data = currentsheet.Range("A2:AW1048576")
   
   For Each cell In Data
   
   If IsError(cell.Value) Then
      cell.Interior.ColorIndex = 3
   End If
   Next
   
   End Sub
   

4. Be prepared for a long wait, since the procedure loops through 51 million cells

5. There are more efficient ways to achieve what you want to do. Update your question if you have a change of mind.

In the controller action append to the header the following lines

    public ActionResult Create(string PositionID)
    {
        Response.AppendHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
        Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.0.
        Response.AppendHeader("Expires", "0"); // Proxies.

string connectionstring="DataSource=severname;InitialCatlog=databasename;Uid=; password=;"
SqlConnection con=new SqlConnection(connectionstring)

I was facing the same issue in bitbucket, and this worked for me:

line1
##<2 white spaces><enter>
line2

The postition:absolute; tag positions the element relative to it's immediate parent. I noticed that even in the examples, there isn't room for scrolling, and when i tried it out, it didn't work. Therefore, to pull off the facebook floating menu, the position:fixed; tag should be used instead. It displaces/keeps the element at the given/specified location, and the rest of the page can scroll smoothly - even with the responsive ones.

Please see CSS postion attribute documentation when you can :)

Below code changes to 'datetime' type and also formats in the given format string. Works well!

df['DOB']=pd.to_datetime(df['DOB'].dt.strftime('%m/%d/%Y'))

If you'd like to have your JAVA_HOME recognised by intellij, you can do one of these:

• Start your intellij from terminal /Applications/IntelliJ IDEA 14.app/Contents/MacOS (this will pick your bash env variables)
• Add login env variable by executing: launchctl setenv JAVA_HOME "/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home"

To directly answer your question, you can add launchctl line in your ~/.bash_profile

As others have answered you can ignore JAVA_HOME by setting up SDK in project structure.

If none of them are working then check this.. say if you have x and y arrays of data along respective axis. Then check in which cell(jupyter) you have initialized x and y to empty. This is because , maybe you are appending data to x and y without re-initializing them. So plot has old data too. So check that..

You have asked two questions, one in the title about the difference between PNG8 and PNG24, which has received a few answers, namely that PNG24 has 8-bit red, green, and blue channels, and PNG-8 has a single 8-bit index into a palette. Naturally, PNG24 usually has a larger filesize than PNG8. Furthermore, PNG8 usually means that it is opaque or has only binary transparency (like GIF); it's defined that way in ImageMagick/GraphicsMagick.

This is an answer to the other one, "I would like to know that if I use either type in my html page, will there be any error? Or is this only quality matter?"

You can put either type on an HTML page and no, this won't cause an error; the files should all be named with the ".png" extension and referred to that way in your HTML. Years ago, early versions of Internet Explorer would not handle PNG with an alpha channel (PNG32) or indexed-color PNG with translucent pixels properly, so it was useful to convert such images to PNG8 (indexed-color with binary transparency conveyed via a PNG tRNS chunk) -- but still use the .png extension, to be sure they would display properly on IE. I think PNG24 was always OK on Internet Explorer because PNG24 is either opaque or has GIF-like single-color transparency conveyed via a PNG tRNS chunk.

The names PNG8 and PNG24 aren't mentioned in the PNG specification, which simply calls them all "PNG". Other names, invented by others, include

• PNG8 or PNG-8 (indexed-color with 8-bit samples, usually means opaque or with GIF-like, binary transparency, but sometimes includes translucency)
• PNG24 or PNG-24 (RGB with 8-bit samples, may have GIF-like transparency via tRNS)
• PNG32 (RGBA with 8-bit samples, opaque, transparent, or translucent)
• PNG48 (Like PNG24 but with 16-bit R,G,B samples)
• PNG64 (like PNG32 but with 16-bit R,G,B,A samples)

There are many more possible combinations including grayscale with 1, 2, 4, 8, or 16-bit samples and indexed PNG with 1, 2, or 4-bit samples (and any of those with transparent or translucent pixels), but those don't have special names.

The vtables are created by the compiler. A class object has a pointer to its vtable. When it starts life, that vtable pointer points to the vtable of the base class. At the end of the constructor code, the compiler generates code to re-point the vtable pointer to the actual vtable for the class. This ensures that constructor code that calls virtual functions calls the base class implementations of those functions, not the override in the class.

maybe:

>>> import datetime
>>> dt0 = datetime.datetime(1,1,1)
>>> td = datetime.timedelta(minutes=34, hours=12, seconds=56)
>>> (dt0+td).strftime('%X')
'12:34:56'
>>> (dt0+td).strftime('%M:%S')
'34:56'
>>> (dt0+td).strftime('%H:%M')
'12:34'
>>>

Since C# 7.0 supports using static directive and Local functions you don't need preprocessor macros for most cases.

df <- read.table(text = 
             "X  Y
             1  2  3
             2  4  5
             3  6  7
             4  8  9
             5 10 11",
             header = TRUE)


y_min <- min(df[,"Y"])

# Corresponding X value
x_val_associated <- df[df$Y == y_min, "X"]

x_val_associated

First, you find the Y min using the min function on the "Y" column only. Notice the returned result is just an integer value. Then, to find the associated X value, you can subset the data.frame to only the rows where the minimum Y value is located and extract just the "X" column.

You now have two integer values for X and Y where Y is the min.

    public static bool IsPositive<T>(T value)
        where T : struct, IComparable<T>
    {
        return value.CompareTo(default(T)) > 0;
    }

just use bash

while read -r line
do
  case "$line" in
    *MYSQL_ROLE=master*)
       echo "do your stuff";;
    *) echo "doesn't exist";;

I know this question is supposedly solved, but I wasn't totally happy with the way it was implemented. I found another source over here on the MSDN blogs that has an overridden XmlTextWriter class that strips out the namespaces. I tweaked it a bit to get some other things I wanted in such as pretty formatting and preserving the root element. Here is what I have in my project at the moment.

http://blogs.msdn.com/b/kaevans/archive/2004/08/02/206432.aspx

Class

/// <summary>
/// Modified XML writer that writes (almost) no namespaces out with pretty formatting
/// </summary>

public class XmlNoNamespaceWriter : XmlTextWriter
{
    private bool _SkipAttribute = false;
    private int _EncounteredNamespaceCount = 0;

    public XmlNoNamespaceWriter(TextWriter writer)
        : base(writer)
    {
        this.Formatting = System.Xml.Formatting.Indented;
    }

    public override void WriteStartElement(string prefix, string localName, string ns)
    {
        base.WriteStartElement(null, localName, null);
    }

    public override void WriteStartAttribute(string prefix, string localName, string ns)
    {
        //If the prefix or localname are "xmlns", don't write it.
        //HOWEVER... if the 1st element (root?) has a namespace we will write it.
        if ((prefix.CompareTo("xmlns") == 0
                || localName.CompareTo("xmlns") == 0)
            && _EncounteredNamespaceCount++ > 0)
        {
            _SkipAttribute = true;
        }
        else
        {
            base.WriteStartAttribute(null, localName, null);
        }
    }

    public override void WriteString(string text)
    {
        //If we are writing an attribute, the text for the xmlns
        //or xmlns:prefix declaration would occur here.  Skip
        //it if this is the case.
        if (!_SkipAttribute)
        {
            base.WriteString(text);
        }
    }

    public override void WriteEndAttribute()
    {
        //If we skipped the WriteStartAttribute call, we have to
        //skip the WriteEndAttribute call as well or else the XmlWriter
        //will have an invalid state.
        if (!_SkipAttribute)
        {
            base.WriteEndAttribute();
        }
        //reset the boolean for the next attribute.
        _SkipAttribute = false;
    }

    public override void WriteQualifiedName(string localName, string ns)
    {
        //Always write the qualified name using only the
        //localname.
        base.WriteQualifiedName(localName, null);
    }
}

Usage

//Save the updated document using our modified (almost) no-namespace XML writer
using(StreamWriter sw = new StreamWriter(this.XmlDocumentPath))
using(XmlNoNamespaceWriter xw = new XmlNoNamespaceWriter(sw))
{
    //This variable is of type `XmlDocument`
    this.XmlDocumentRoot.Save(xw);
}

Using Linq to find the object you can do:

var obj = myList.FirstOrDefault(x => x.MyProperty == myValue);
if (obj != null) obj.OtherProperty = newValue;

But in this case you might want to save the List into a Dictionary and use this instead:

// ... define after getting the List/Enumerable/whatever
var dict = myList.ToDictionary(x => x.MyProperty);
// ... somewhere in code
MyObject found;
if (dict.TryGetValue(myValue, out found)) found.OtherProperty = newValue;

Looking for EventHandling, ActionListener?

or code?

JButton b = new JButton("Clear");
b.addActionListener(new ActionListener(){
    public void actionPerformed(ActionEvent e){
        textfield.setText("");
        //textfield.setText(null); //or use this
    }
});

You can verify where your Setting.xml is by pressing shortcut Ctrl+3, you will see Quick Access on top right side of Eclipse, then search setting.xml in searchbox. If you got setting.xml it will show up in search. Click that, and it will open the window showing directory path wherever it is stored. Your Maven Global Settings should be as such:

Global Setting C:\maven\apache-maven-3.5.0\conf\settings.xml
User Setting %userprofile%\\.m2\setting.xml
You can use global setting usually and leave the second option user setting untouched. Store your setting.xml in Global Setting

One way to give preference to specific rows is to add a large number to their priority. You can do this with a CASE statement:

  select id, name, priority
    from mytable
order by priority + CASE WHEN name='core' THEN 1000 ELSE 0 END desc

:focus is when an element is able to accept input - the cursor in a input box or a link that has been tabbed to.

:active is when an element is being activated by a user - the time between when a user presses a mouse button and then releases it.

$('div').html('');

But why are you clearing, divToUpdate.html(data); will completely replace the old HTML.

You can set the width in pixels via inline styling:

<input type="text" name="text" style="width: 195px;">

You can also set the width with a visible character length:

<input type="text" name="text" size="35">

I know it's now 2020, but I couldn't see an answer that satisfied the "ignore" part of the question. Turns out, you can tell TSLint to do just that using a directive;

// @ts-ignore
this.x = this.x.filter(x => x.someProp !== false);

Normally this would throw an error, stating that 'someProp does not exist on type'. With the comment, that error goes away.

This will stop any errors being thrown when compiling and should also stop your IDE complaining at you.

To understand why we need constraints, you must first understand the value of data integrity.

Data Integrity refers to the validity of data. Are your data valid? Are your data representing what you have designed them to?

What weird questions I ask you might think, but sadly enough all too often, databases are filled with garbage data, invalid references to rows in other tables, that are long gone... and values that doesn't mean anything to the business logic of your solution any longer.

All this garbage is not alone prone to reduce your performance, but is also a time-bomb under your application logic that eventually will retreive data that it is not designed to understand.

Constraints are rules you create at design-time that protect your data from becoming corrupt. It is essential for the long time survival of your heart child of a database solution. Without constraints your solution will definitely decay with time and heavy usage.

You have to acknowledge that designing your database design is only the birth of your solution. Here after it must live for (hopefully) a long time, and endure all kinds of (strange) behaviour by its end-users (ie. client applications). But this design-phase in development is crucial for the long-time success of your solution! Respect it, and pay it the time and attention it requires.

A wise man once said: "Data must protect itself!". And this is what constraints do. It is rules that keep the data in your database as valid as possible.

There are many ways of doing this, but basically they boil down to:

• Foreign key constraints is probably the most used constraint, and ensures that references to other tables are only allowed if there actually exists a target row to reference. This also makes it impossible to break such a relationship by deleting the referenced row creating a dead link.
• Check constraints can ensure that only specific values are allowed in certain column. You could create a constraint only allowing the word 'Yellow' or 'Blue' in a VARCHAR column. All other values would yield an error. Get ideas for usage of check constraints check the sys.check_constraints view in the AdventureWorks sample database
• Rules in SQL Server are just reusable Check Constraints (allows you to maintain the syntax from a single place, and making it easier to deploy your constraints to other databases)

As I've hinted here, it takes some thorough considerations to construct the best and most defensive constraint approach for your database design. You first need to know the possibilities and limitations of the different constraint types above. Further reading could include:

FOREIGN KEY Constraints - Microsoft

Foreign key constraint - w3schools

Good luck! ;)

This error message appears if the Windows service launcher has quit immediately after being started. This problem usually happens because the license key has not been correctly deployed(license.txt file in the license folder). If service is not strtign with correct key, just put incorrect key and try to start. Once started, place the correct key, it will work.

In Java 8 it can be done with:

String s = "edcba".chars()
    .sorted()
    .collect(StringBuilder::new, StringBuilder::appendCodePoint, StringBuilder::append)
    .toString();

A slightly shorter alternative that works with a Stream of Strings of length one (each character in the unsorted String is converted into a String in the Stream) is:

String sorted =
    Stream.of("edcba".split(""))
        .sorted()
        .collect(Collectors.joining());

Union has not good performance : this article describe about compare them with together

var dict = list2.ToDictionary(p => p.Number);
foreach (var person in list1)
{
        dict[person.Number] = person;
}
var merged = dict.Values.ToList();

Lists and LINQ merge: 4820ms
Dictionary merge: 16ms
HashSet and IEqualityComparer: 20ms
LINQ Union and IEqualityComparer: 24ms

You can also achieve similar results by using 'query' and @:

eg:

df = pd.DataFrame({'A': [1, 2, 3], 'B': ['a', 'b', 'f']})
df = pd.DataFrame({'A' : [5,6,3,4], 'B' : [1,2,3, 5]})
list_of_values = [3,6]
result= df.query("A in @list_of_values")
result
   A  B
1  6  2
2  3  3

CGI is a mechanism whereby an external program is called by the web server in order to handle a request, with environment variables and standard input being used to feed the request data to the program. The exact language the external program is written in does not matter, although it is easier to write CGI programs in some languages versus others.

Since CGI scripts need execute permissions, httpd by default only allows CGI programs in the cgi-bin directory to be run for (possibly now misguided) security purposes.

Most PHP scripts run in the web server process via mod_php. This is not CGI.

CGI is slow since the program (and related interpreter) must be started up per request. Modern alternatives are embedded execution, used by mod_php, and long-running processes, used by FastCGI. A given language may have its own way of implementing those mechanisms, so be sure to ask around before resorting to CGI.

You need to edit the Tomcat/conf/server.xml and change the connector port. The connector setting should look something like this:

<Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

Just change the connector port from default 8080 to another valid port number.

You should be injecting NameService inside providers array of your AppModule's NgModule metadata.

@NgModule({
   imports: [BrowserModule, ...],
   declarations: [...],
   bootstrap: [AppComponent],
   //inject providers below if you want single instance to be share amongst app
   providers: [MyService]
})
export class AppModule {

}

If you want to create an Dependency for particular component level without bothering about state of your application, then you can inject that dependency on component providers metadata option like accepted @Klass answer shown.

With EL 2 (Expression Language 2) you can use this type of construct for your question:

    #{formatBean.format(myBean.birthdate)}

Or you can add an alternate getter in your bean resulting in

    #{myBean.birthdateString}

where getBirthdateString returns the proper text representation. Remember to annotate the get method as @Transient if it is an Entity.

I always thought that for a task that trivial, I wouldn't want to import anything. But i may be wrong, depending on collections.Counter being faster or not.

items = "Whats the simpliest way to add the list items to a dictionary "

stats = {}
for i in items:
    if i in stats:
        stats[i] += 1
    else:
        stats[i] = 1

# bonus
for i in sorted(stats, key=stats.get):
    print("%d×'%s'" % (stats[i], i))

I think this may be preferable to using count(), because it will only go over the iterable once, whereas count may search the entire thing on every iteration. I used this method to parse many megabytes of statistical data and it always was reasonably fast.

As of PowerShell 4.0 (Windows 8.1/Server 2012 R2) it is possible to make a certificate in Windows without makecert.exe.

The commands you need are New-SelfSignedCertificate and Export-PfxCertificate.

Instructions are in Creating Self Signed Certificates with PowerShell.

Just use

$location.url();

Instead of

$location.path();

PowerShell Fun

Get-WmiObject win32_logicaldisk -Computername <ServerName> -Credential $(get-credential) | Select DeviceID,VolumeName,FreeSpace,Size | where {$_.DeviceID -eq "C:"}

If you wish to read only access to the string you can use array notation directly.

Type "help", "copyright", "credits" or "license" for more information.
>>> t = 'my string'
>>> t[1]
'y'

Could be useful for testing without using regexp. Does the string contain an ending newline?

>>> t[-1] == '\n'
False
>>> t = 'my string\n'
>>> t[-1] == '\n'
True

The Range object has both width and height properties, which are measured in points.

Subject is the certificate's common name and is a critical property for the certificate in a lot of cases if it's a server certificate and clients are looking for a positive identification.

As an example on an SSL certificate for a web site the subject would be the domain name of the web site.

For me it was a load balancer/url issue. A web service behind a load balancer called another service behind the same load balancer using the full url like: loadbalancer.mycompany.com. I changed it to bypass the load balancer when calling the second service by using localhost.mycompany.com instead.

I think there was some kind of circular reference issue going on with the load balancer.

If listOfIds is a list, this will work, but, List.Contains() is a linear search, so this isn't terribly efficient.

You're better off storing the ids you want to look up into a container that is suited for searching, like Set.

List<int> listOfIds = new List(GetListOfIds());
lists.Where(r=>listOfIds.Contains(r.Id));

git push --follow-tags

This is a sane option introduced in Git 1.8.3:

git push --follow-tags

It pushes both commits and only tags that are both:

• annotated
• reachable (an ancestor) from the pushed commits

This is sane because:

• you should only push annotated tags to the remote, and keep lightweight tags for local development to avoid tag clashes. See also: What is the difference between an annotated and unannotated tag?
• it won't push annotated tags on unrelated branches

It is for those reasons that --tags should be avoided.

Git 2.4 has added the push.followTags option to turn that flag on by default which you can set with:

git config --global push.followTags true

or by adding followTags = true to the [push] section of your ~/.gitconfig file.

This is going to work for all situations while working with width.

`<asp:TemplateField HeaderText="DATE">
   <ItemTemplate>
   <asp:Label ID="Label1" runat="server" Text='<%# Bind("date") %>' Width="100px"></asp:Label>
   </ItemTemplate>
  </asp:TemplateField>`

Using just one call to replace (regex version): var bgUrl = $('#element-id').css('background-image').replace(/url\(("|')(.+)("|')\)/gi, '$2');

You can multiply numpy arrays by scalars and it just works.

>>> import numpy as np
>>> np.array([1, 2, 3]) * 2
array([2, 4, 6])
>>> np.array([[1, 2, 3], [4, 5, 6]]) * 2
array([[ 2,  4,  6],
       [ 8, 10, 12]])

This is also a very fast and efficient operation. With your example:

>>> a_1 = np.array([1.0, 2.0, 3.0])
>>> a_2 = np.array([[1., 2.], [3., 4.]])
>>> b = 2.0
>>> a_1 * b
array([2., 4., 6.])
>>> a_2 * b
array([[2., 4.],
       [6., 8.]])

New Selenium libraries are now out, according to: https://github.com/SeleniumHQ/selenium/issues/2110

The download page http://www.seleniumhq.org/download/ seems not to be updated just yet, but by adding 1 to the minor version in the link, I could download the C# version: http://selenium-release.storage.googleapis.com/2.53/selenium-dotnet-2.53.1.zip

It works for me with Firefox 47.0.1.

As a side note, I was able build just the webdriver.xpi Firefox extension from the master branch in GitHub, by running ./go //javascript/firefox-driver:webdriver:run – which gave an error message but did build the build/javascript/firefox-driver/webdriver.xpi file, which I could rename (to avoid a name clash) and successfully load with the FirefoxProfile.AddExtension method. That was a reasonable workaround without having to rebuild the entire Selenium library.

Do as below create class and call it like this

Check : Reset all Controls (Textbox, ComboBox, CheckBox, ListBox) in a Windows Form using C#

private void button1_Click(object sender, EventArgs e)
{
   Utilities.ResetAllControls(this);
}

public class Utilities
    {
        public static void ResetAllControls(Control form)
        {
            foreach (Control control in form.Controls)
            {
                if (control is TextBox)
                {
                    TextBox textBox = (TextBox)control;
                    textBox.Text = null;
                }

                if (control is ComboBox)
                {
                    ComboBox comboBox = (ComboBox)control;
                    if (comboBox.Items.Count > 0)
                        comboBox.SelectedIndex = 0;
                }

                if (control is CheckBox)
                {
                    CheckBox checkBox = (CheckBox)control;
                    checkBox.Checked = false;
                }

                if (control is ListBox)
                {
                    ListBox listBox = (ListBox)control;
                    listBox.ClearSelected();
                }
            }
        }      
    }

... Thanks guys... all I needed was the 'value' of the checked radio button where each radio button in the set had a different id...

 var user_cat = $("input[name='user_cat']:checked").val();

works for me...

Gustavomcls's solution to change com.google.* version to same version worked for me .

I change both dependancies to 9.2.1 in buid.gradle (Module:app)

compile 'com.google.firebase:firebase-ads:9.2.1'
compile 'com.google.android.gms:play-services:9.2.1'

git diff --name-only --diff-filter=U | xargs git checkout --theirs

Seems to do the job. Note that you have to be cd'ed to the root directory of the git repo to achieve this.

Set FormsBorderStyle of the Form to None.

If you do, it's up to you how to implement the dragging and closing functionality of the window.

You can use String.Remove to delete from a specified position to the end of the string.

myString = myString.Remove(myString.Length - 3);

An endpoint is the 'connection point' of a service, tool, or application accessed over a network. In the world of software, any software application that is running and "listening" for connections uses an endpoint as the "front door." When you want to connect to the application/service/tool to exchange data you connect to its endpoint

Try this to move your table (tbl1) to tablespace (tblspc2).

alter table tb11 move tablespace tblspc2;

#define ID_LEN 5

int variableNumberOfElements = 5; /* Hard coded here */

orderedIds = (char **)malloc(variableNumberOfElements * (ID_LEN + 1) * sizeof(char));

Quick guide to setup a cron job

Create a new text file, example: mycronjobs.txt

For each daily job (00:00, 03:45), save the schedule lines in mycronjobs.txt

00 00 * * * ruby path/to/your/script.rb
45 03 * * * path/to/your/script2.sh

Send the jobs to cron (everytime you run this, cron deletes what has been stored and updates with the new information in mycronjobs.txt)

crontab mycronjobs.txt

Extra Useful Information

See current cron jobs

crontab -l

Remove all cron jobs

crontab -r

You can use php built in CONCAT() for this.

SELECT CONCAT(`name`, ' ', `email`) as password_email FROM `table`;

change filed name as your requirement

then the result is

and if you want to concat same filed using other field which same then

SELECT filed1 as category,filed2 as item, GROUP_CONCAT(CAST(filed2 as CHAR)) as item_name FROM `table` group by filed1 

then this is output

TL;DR

mysql_real_escape_string() will provide no protection whatsoever (and could furthermore munge your data) if:

• MySQL's NO_BACKSLASH_ESCAPES SQL mode is enabled (which it might be, unless you explicitly select another SQL mode every time you connect); and

• your SQL string literals are quoted using double-quote " characters.

This was filed as bug #72458 and has been fixed in MySQL v5.7.6 (see the section headed "The Saving Grace", below).

This is another, (perhaps less?) obscure EDGE CASE!!!

In homage to @ircmaxell's excellent answer (really, this is supposed to be flattery and not plagiarism!), I will adopt his format:

The Attack

Starting off with a demonstration...

mysql_query('SET SQL_MODE="NO_BACKSLASH_ESCAPES"'); // could already be set
$var = mysql_real_escape_string('" OR 1=1 -- ');
mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');

This will return all records from the test table. A dissection:

1. Selecting an SQL Mode

   mysql_query('SET SQL_MODE="NO_BACKSLASH_ESCAPES"');
   

   As documented under String Literals:

   There are several ways to include quote characters within a string:

   • A “'” inside a string quoted with “'” may be written as “''”.

   • A “"” inside a string quoted with “"” may be written as “""”.

   • Precede the quote character by an escape character (“\”).

   • A “'” inside a string quoted with “"” needs no special treatment and need not be doubled or escaped. In the same way, “"” inside a string quoted with “'” needs no special treatment.

   If the server's SQL mode includes NO_BACKSLASH_ESCAPES, then the third of these options—which is the usual approach adopted by mysql_real_escape_string()—is not available: one of the first two options must be used instead. Note that the effect of the fourth bullet is that one must necessarily know the character that will be used to quote the literal in order to avoid munging one's data.

2. The Payload

   " OR 1=1 -- 
   

   The payload initiates this injection quite literally with the " character. No particular encoding. No special characters. No weird bytes.

3. mysql_real_escape_string()

   $var = mysql_real_escape_string('" OR 1=1 -- ');
   

   Fortunately, mysql_real_escape_string() does check the SQL mode and adjust its behaviour accordingly. See libmysql.c:

   ulong STDCALL
   mysql_real_escape_string(MYSQL *mysql, char *to,const char *from,
                ulong length)
   {
     if (mysql->server_status & SERVER_STATUS_NO_BACKSLASH_ESCAPES)
       return escape_quotes_for_mysql(mysql->charset, to, 0, from, length);
     return escape_string_for_mysql(mysql->charset, to, 0, from, length);
   }
   

   Thus a different underlying function, escape_quotes_for_mysql(), is invoked if the NO_BACKSLASH_ESCAPES SQL mode is in use. As mentioned above, such a function needs to know which character will be used to quote the literal in order to repeat it without causing the other quotation character from being repeated literally.

   However, this function arbitrarily assumes that the string will be quoted using the single-quote ' character. See charset.c:

   /*
     Escape apostrophes by doubling them up
   
   // [ deletia 839-845 ]
   
     DESCRIPTION
       This escapes the contents of a string by doubling up any apostrophes that
       it contains. This is used when the NO_BACKSLASH_ESCAPES SQL_MODE is in
       effect on the server.
   
   // [ deletia 852-858 ]
   */
   
   size_t escape_quotes_for_mysql(CHARSET_INFO *charset_info,
                                  char *to, size_t to_length,
                                  const char *from, size_t length)
   {
   // [ deletia 865-892 ]
   
       if (*from == '\'')
       {
         if (to + 2 > to_end)
         {
           overflow= TRUE;
           break;
         }
         *to++= '\'';
         *to++= '\'';
       }
   

   So, it leaves double-quote " characters untouched (and doubles all single-quote ' characters) irrespective of the actual character that is used to quote the literal! In our case $var remains exactly the same as the argument that was provided to mysql_real_escape_string()—it's as though no escaping has taken place at all.

4. The Query

   mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');
   

   Something of a formality, the rendered query is:

   SELECT * FROM test WHERE name = "" OR 1=1 -- " LIMIT 1
   

As my learned friend put it: congratulations, you just successfully attacked a program using mysql_real_escape_string()...

The Bad

mysql_set_charset() cannot help, as this has nothing to do with character sets; nor can mysqli::real_escape_string(), since that's just a different wrapper around this same function.

The problem, if not already obvious, is that the call to mysql_real_escape_string() cannot know with which character the literal will be quoted, as that's left to the developer to decide at a later time. So, in NO_BACKSLASH_ESCAPES mode, there is literally no way that this function can safely escape every input for use with arbitrary quoting (at least, not without doubling characters that do not require doubling and thus munging your data).

The Ugly

It gets worse. NO_BACKSLASH_ESCAPES may not be all that uncommon in the wild owing to the necessity of its use for compatibility with standard SQL (e.g. see section 5.3 of the SQL-92 specification, namely the <quote symbol> ::= <quote><quote> grammar production and lack of any special meaning given to backslash). Furthermore, its use was explicitly recommended as a workaround to the (long since fixed) bug that ircmaxell's post describes. Who knows, some DBAs might even configure it to be on by default as means of discouraging use of incorrect escaping methods like addslashes().

Also, the SQL mode of a new connection is set by the server according to its configuration (which a SUPER user can change at any time); thus, to be certain of the server's behaviour, you must always explicitly specify your desired mode after connecting.

The Saving Grace

So long as you always explicitly set the SQL mode not to include NO_BACKSLASH_ESCAPES, or quote MySQL string literals using the single-quote character, this bug cannot rear its ugly head: respectively escape_quotes_for_mysql() will not be used, or its assumption about which quote characters require repeating will be correct.

For this reason, I recommend that anyone using NO_BACKSLASH_ESCAPES also enables ANSI_QUOTES mode, as it will force habitual use of single-quoted string literals. Note that this does not prevent SQL injection in the event that double-quoted literals happen to be used—it merely reduces the likelihood of that happening (because normal, non-malicious queries would fail).

In PDO, both its equivalent function PDO::quote() and its prepared statement emulator call upon mysql_handle_quoter()—which does exactly this: it ensures that the escaped literal is quoted in single-quotes, so you can be certain that PDO is always immune from this bug.

As of MySQL v5.7.6, this bug has been fixed. See change log:

Functionality Added or Changed

• Incompatible Change: A new C API function, mysql_real_escape_string_quote(), has been implemented as a replacement for mysql_real_escape_string() because the latter function can fail to properly encode characters when the NO_BACKSLASH_ESCAPES SQL mode is enabled. In this case, mysql_real_escape_string() cannot escape quote characters except by doubling them, and to do this properly, it must know more information about the quoting context than is available. mysql_real_escape_string_quote() takes an extra argument for specifying the quoting context. For usage details, see mysql_real_escape_string_quote().

   Note

  Applications should be modified to use mysql_real_escape_string_quote(), instead of mysql_real_escape_string(), which now fails and produces an CR_INSECURE_API_ERR error if NO_BACKSLASH_ESCAPES is enabled.

  References: See also Bug #19211994.

Safe Examples

Taken together with the bug explained by ircmaxell, the following examples are entirely safe (assuming that one is either using MySQL later than 4.1.20, 5.0.22, 5.1.11; or that one is not using a GBK/Big5 connection encoding):

mysql_set_charset($charset);
mysql_query("SET SQL_MODE=''");
$var = mysql_real_escape_string('" OR 1=1 /*');
mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');

...because we've explicitly selected an SQL mode that doesn't include NO_BACKSLASH_ESCAPES.

mysql_set_charset($charset);
$var = mysql_real_escape_string("' OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

...because we're quoting our string literal with single-quotes.

$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(["' OR 1=1 /*"]);

...because PDO prepared statements are immune from this vulnerability (and ircmaxell's too, provided either that you're using PHP=5.3.6 and the character set has been correctly set in the DSN; or that prepared statement emulation has been disabled).

$var  = $pdo->quote("' OR 1=1 /*");
$stmt = $pdo->query("SELECT * FROM test WHERE name = $var LIMIT 1");

...because PDO's quote() function not only escapes the literal, but also quotes it (in single-quote ' characters); note that to avoid ircmaxell's bug in this case, you must be using PHP=5.3.6 and have correctly set the character set in the DSN.

$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "' OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

...because MySQLi prepared statements are safe.

Wrapping Up

Thus, if you:

• use native prepared statements

OR

• use MySQL v5.7.6 or later

OR

• in addition to employing one of the solutions in ircmaxell's summary, use at least one of:

  • PDO;
  • single-quoted string literals; or
  • an explicitly set SQL mode that does not include NO_BACKSLASH_ESCAPES

...then you should be completely safe (vulnerabilities outside the scope of string escaping aside).

Mine is a bit more smaller and simpler:

/// <summary>
/// Runs a PowerShell script taking it's path and parameters.
/// </summary>
/// <param name="scriptFullPath">The full file path for the .ps1 file.</param>
/// <param name="parameters">The parameters for the script, can be null.</param>
/// <returns>The output from the PowerShell execution.</returns>
public static ICollection<PSObject> RunScript(string scriptFullPath, ICollection<CommandParameter> parameters = null)
{
    var runspace = RunspaceFactory.CreateRunspace();
    runspace.Open();
    var pipeline = runspace.CreatePipeline();
    var cmd = new Command(scriptFullPath);
    if (parameters != null)
    {
        foreach (var p in parameters)
        {
            cmd.Parameters.Add(p);
        }
    }
    pipeline.Commands.Add(cmd);
    var results = pipeline.Invoke();
    pipeline.Dispose();
    runspace.Dispose();
    return results;
}

I guess problem is in width attributes in table and td remove 'px' for example

<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">

Should be

<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">

SELECT CURRENT_USER usr, :'HOST' host, inet_server_port() port;

This uses psql's built in HOST variable, documented here

And postgres System Information Functions, documented here

Policykit is a system daemon and policykit authentication agent is used to verify identity of the user before executing actions. The messages logged in /var/log/secure show that an authentication agent is registered when user logs in and it gets unregistered when user logs out. These messages are harmless and can be safely ignored.

if you want to populate a table in SQL SERVER you can use while statement as follows:

declare @llenandoTabla INT = 0;
while @llenandoTabla < 10000
begin
insert into employeestable // Name of my table
(ID, FIRSTNAME, LASTNAME, GENDER, SALARY) // Parameters of my table
VALUES 
(555, 'isaias', 'perez', 'male', '12220') //values
set @llenandoTabla = @llenandoTabla + 1;
end

Hope it helps.

If you just want to know about your screen width, you can just search for "smallest screen width" in your developer options. You can even edit it.

If you're using ReSharper, go into the ReSharper menu → Code → Generate...

(Or hit Alt + Ins inside the surrounding class), and you'll get all the options for generating getters and/or setters you can think of :-)

MySQL DELETE records with JOIN

You generally use INNER JOIN in the SELECT statement to select records from a table that have corresponding records in other tables. We can also use the INNER JOIN clause with the DELETE statement to delete records from a table and also the corresponding records in other tables e.g., to delete records from both T1 and T2 tables that meet a particular condition, you use the following statement:

DELETE T1, T2
FROM T1
INNER JOIN T2 ON T1.key = T2.key
WHERE condition

Notice that you put table names T1 and T2 between DELETE and FROM. If you omit the T1 table, the DELETE statement only deletes records in the T2 table, and if you omit the T2 table, only records in the T1 table are deleted.

The join condition T1.key = T2.key specifies the corresponding records in the T2 table that need be deleted.

The condition in the WHERE clause specifies which records in the T1 and T2 that need to be deleted.

a=input("Enter number:")

def isprime(): 

    total=0
    factors=(1,a)# The only factors of a number
    pfactors=range(1,a+1) #considering all possible factors


    if a==1 or a==0:# One and Zero are not prime numbers
        print "%d is NOT prime"%a


    elif a==2: # Two is the only even prime number
        print "%d is  prime"%a


    elif a%2==0:#Any even number is not prime except two
        print "%d is NOT prime"%a  



    else:#a number is prime if its multiples are 1 and itself 
         #The sum of the number that return zero moduli should be equal to the "only" factors
        for number in pfactors: 
            if (a%number)==0: 
                total+=number
        if total!=sum(factors):
            print "%d is NOT prime"%a 
        else:
             print "%d is  prime"%a
isprime()

Backspace and tab both move the cursor position. Neither is truly a 'printable' character.

Your code says:

1. print "foo"
2. move the cursor back one space
3. move the cursor forward to the next tabstop
4. output "bar".

To get the output you expect, you need printf("foo\b \tbar"). Note the extra 'space'. That says:

1. output "foo"
2. move the cursor back one space
3. output a ' ' (this replaces the second 'o').
4. move the cursor forward to the next tabstop
5. output "bar".

Most of the time it is inappropriate to use tabs and backspace for formatting your program output. Learn to use printf() formatting specifiers. Rendering of tabs can vary drastically depending on how the output is viewed.

This little script shows one way to alter your terminal's tab rendering. Tested on Ubuntu + gnome-terminal:

#!/bin/bash
tabs -8 
echo -e "\tnormal tabstop"
for x in `seq 2 10`; do
  tabs $x
  echo -e "\ttabstop=$x"
 done

tabs -8
echo -e "\tnormal tabstop"

Also see man setterm and regtabs.

And if you redirect your output or just write to a file, tabs will quite commonly be displayed as fewer than the standard 8 chars, especially in "programming" editors and IDEs.

So in otherwords:

printf("%-8s%s", "foo", "bar"); /* this will ALWAYS output "foo     bar" */
printf("foo\tbar"); /* who knows how this will be rendered */

IMHO, tabs in general are rarely appropriate for anything. An exception might be generating output for a program that requires tab-separated-value input files (similar to comma separated value).

Backspace '\b' is a different story... it should never be used to create a text file since it will just make a text editor spit out garbage. But it does have many applications in writing interactive command line programs that cannot be accomplished with format strings alone. If you find yourself needing it a lot, check out "ncurses", which gives you much better control over where your output goes on the terminal screen. And typically, since it's 2011 and not 1995, a GUI is usually easier to deal with for highly interactive programs. But again, there are exceptions. Like writing a telnet server or console for a new scripting language.

Another possible solution is to compare current date with January 1, 1970, you can get January 1, 1970 by new Date(0);

var date = new Date(); 
var myDate= date - new Date(0);

Short and sweet, no additional modules needed:

my $toDate = `date +%m/%d/%Y" "%l:%M:%S" "%p`;

Output for example would be: 04/25/2017 9:30:33 AM

SUBSTR will be better than FLOOR in some cases because FLOOR has a "bug" as follow:

SELECT 25 * 9.54 + 0.5 -> 239.00

SELECT FLOOR(25 * 9.54 + 0.5) -> 238  (oops!)

SELECT SUBSTR((25*9.54+0.5),1,LOCATE('.',(25*9.54+0.5)) - 1) -> 239

you should have three tables: users, comments and comment_users.

comment_users has just two fields: fk_user_id and fk_comment_id

That way you can keep your performance up to a maximum :)

The problem lays here:

--This result set has 3 columns
select LOC_id,LOC_locatie,LOC_deelVan_LOC_id from tblLocatie t
where t.LOC_id = 1 -- 1 represents an example

union all

--This result set has 1 columns   
select t.LOC_locatie + '>' from tblLocatie t
inner join q parent on parent.LOC_id = t.LOC_deelVan_LOC_id

In order to use union or union all number of columns and their types should be identical cross all result sets.

I guess you should just add the column LOC_deelVan_LOC_id to your second result set

Forward Warning

Just a quick headsup to those visiting this and other similar threads looking for a way to parallelize EntityFramework using async+await+task tool-set: The pattern shown here is sound, however, when it comes to the special snowflake of EF you will not achieve parallel execution unless and until you use a separate (new) db-context-instance inside each and every *Async() call involved.

This sort of thing is necessary due to inherent design limitations of ef-db-contexts which forbid running multiple queries in parallel in the same ef-db-context instance.

Capitalizing on the answers already given, this is the way to make sure that you collect all values even in the case that one or more of the tasks results in an exception:

  public async Task<string> Foobar() {
    async Task<string> Awaited(Task<Cat> a, Task<House> b, Task<Tesla> c) {
        return DoSomething(await a, await b, await c);
    }

    using (var carTask = BuyCarAsync())
    using (var catTask = FeedCatAsync())
    using (var houseTask = SellHouseAsync())
    {
        if (carTask.Status == TaskStatus.RanToCompletion //triple
            && catTask.Status == TaskStatus.RanToCompletion //cache
            && houseTask.Status == TaskStatus.RanToCompletion) { //hits
            return Task.FromResult(DoSomething(catTask.Result, carTask.Result, houseTask.Result)); //fast-track
        }

        cat = await catTask;
        car = await carTask;
        house = await houseTask;
        //or Task.AwaitAll(carTask, catTask, houseTask);
        //or await Task.WhenAll(carTask, catTask, houseTask);
        //it depends on how you like exception handling better

        return Awaited(catTask, carTask, houseTask);
   }
 }

An alternative implementation that has more or less the same performance characteristics could be:

 public async Task<string> Foobar() {
    using (var carTask = BuyCarAsync())
    using (var catTask = FeedCatAsync())
    using (var houseTask = SellHouseAsync())
    {
        cat = catTask.Status == TaskStatus.RanToCompletion ? catTask.Result : (await catTask);
        car = carTask.Status == TaskStatus.RanToCompletion ? carTask.Result : (await carTask);
        house = houseTask.Status == TaskStatus.RanToCompletion ? houseTask.Result : (await houseTask);

        return DoSomething(cat, car, house);
     }
 }

size_t is the type used to represent sizes (as its names implies). Its platform (and even potentially implementation) dependent, and should be used only for this purpose. Obviously, representing a size, size_t is unsigned. Many stdlib functions, including malloc, sizeof and various string operation functions use size_t as a datatype.

An int is signed by default, and even though its size is also platform dependant, it will be a fixed 32bits on most modern machine (and though size_t is 64 bits on 64-bits architecture, int remain 32bits long on those architectures).

To summarize : use size_t to represent the size of an object and int (or long) in other cases.

You can wire the CheckedEvents of all the buttons against one handler. There you can easily get the correct Checkbox.

// Wire all events into this.
private void AllCheckBoxes_CheckedChanged(Object sender, EventArgs e) {
    // Check of the raiser of the event is a checked Checkbox.
    // Of course we also need to to cast it first.
    if (((RadioButton)sender).Checked) {
        // This is the correct control.
        RadioButton rb = (RadioButton)sender;
    }
}

It can be done like this:

import numpy as np

# create a random matrix:
A = np.random.normal(size=(5,2))

# add a column of zeros to it:
print(np.hstack((A,np.zeros((A.shape[0],1)))))

In general, if A is an m*n matrix, and you need to add a column, you have to create an n*1 matrix of zeros, then use "hstack" to add the matrix of zeros to the right of the matrix A.

Tags are labels you use to mark up the begining and end of an element.

All tags have the same format: they begin with a less-than sign "<" and end with a greater-than sign ">".

Generally speaking, there are two kinds of tags - opening tags: <html> and closing tags: </html>. The only difference between an opening tag and a closing tag is the forward slash "/". You label content by putting it between an opening tag and a closing tag.

HTML is all about elements. To learn HTML is to learn and use different tags.

For example:

<h1></h1>

Where as elements are something that consists of start tag and end tag as shown:

<h1>Heading</h1>

setTimeout(() => { emailGroup.disable(); });

Now there's a dedicated function on console for that:

console.trace()

// Embarcadero C++ Builder 

// convertion string to wstring
string str1 = "hello";
String str2 = str1;         // typedef UnicodeString String;   -> str2 contains now u"hello";

// convertion wstring to string
String str2 = u"hello";
string str1 = UTF8string(str2).c_str();   // -> str1 contains now "hello"

Before reconfiguring the global excludes file, you might want to check what it's currently configured to, using this command:

git config --get core.excludesfile

In my case, when I ran it I saw my global excludes file was configured to

~/.gitignore_global

Use the Apache commons lang3 lib instead

 EnumUtils.isValidEnum(MyEnum.class, myValue)

It is unfortunately not supported in older versions of MSTest. Apparently there is an extensibility model and you can implement it yourself. Another option would be to use data-driven tests.

My personal opinion would be to just stick with NUnit though...

As of Visual Studio 2012, update 1, MSTest has a similar feature. See McAden's answer.

wtluo, great ! May I propose a slight modification of your code 2. ? Here it is:

for i, detected_box in enumerate(detect_boxes):
    box = detected_box["box"]
    face_img = img[ box[1]:box[1] + box[3], box[0]:box[0] + box[2] ]
    cv2.imwrite("face-{:03d}.jpg".format(i+1), face_img)

Just set the img css to be display:inline or display:inline-block

Just use the standard library in C++:

#include <bitset>

You need a variable of type std::bitset:

std::bitset<8ul> x;
x = std::bitset<8>(10);
for (int i = x.size() - 1; i >= 0; i--) {
      std::cout << x[i];
}

In this example, I stored the binary form of 10 in x.

8ul defines the size of your bits, so 7ul means seven bits and so on.

You should set property file name without .properties extension, it works correctly for me:)

I know this is old. But yeah. I prefer much shorter solution, than Giona answer

[contenteditable] {
    border-bottom: 1px solid transparent;
    &:focus {outline: none; border-bottom: 1px dashed #000;}
}

If the top answers don't work, look for a config named PrecompiledApp.config in the hosting directory and delete it if it exists. This file prevents IISExpress and LocalIIS to work properly. (And I think that's a bug) The content of the file in my case was:

<precompiledApp version="2" updatable="true"/>

And I'm 100% positive that was the problem with my case since I tried everything in 2 hours and tested lots of times with this config.

One more thing: You cannot use aspnet_regiis in newer versions of Windows and IIS so try

dism /online /enable-feature /featurename:IIS-ASPNET45 /all

Also, if you can't change class B, you can fix the error by using multiple inheritance.

class B:
    def meth(self, arg):
        print arg

class C(B, object):
    def meth(self, arg):
        super(C, self).meth(arg)

print C().meth(1)

Finally I found the solution, that works for me:

jQuery.ajax ({
    url: myurl,
    type: "POST",
    data: JSON.stringify({data:"test"}),
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function(){
        //
    }
});

Suppose you want to search "column" in "Table" and you want case insenstive search. The best and efficient way is as below;

//create empty JSON Object
mycolumn = {};

//check if column has valid value
if(column) {
    mycolumn.column = {$regex: new RegExp(column), $options: "i"};
}
Table.find(mycolumn);

Above code just adds your search value as RegEx and searches in with insensitve criteria set with "i" as option.

All the best.

The name of the DOM function is actually getElementsByClassName, not getElementByClassName, simply because more than one element on the page can have the same class, hence: Elements.

The return value of this will be a NodeList instance, or a superset of the NodeList (FF, for instance returns an instance of HTMLCollection). At any rate: the return value is an array-like object:

var y = document.getElementsByClassName('foo');
var aNode = y[0];

If, for some reason you need the return object as an array, you can do that easily, because of its magic length property:

var arrFromList = Array.prototype.slice.call(y);
//or as per AntonB's comment:
var arrFromList = [].slice.call(y);

As yckart suggested querySelector('.foo') and querySelectorAll('.foo') would be preferable, though, as they are, indeed, better supported (93.99% vs 87.24%), according to caniuse.com:

• querySelector(all)
• getElementsByClassName
• Don't use w3schools to learn something
• Refer to MDN for accurate information

Since you say you're using Java 5, you can use setInt with an Integer due to autounboxing: pstmt.setInt(1, tempID) should work just fine. In earlier versions of Java, you would have had to call .intValue() yourself.

The opposite works as well... assigning an int to an Integer will automatically cause the int to be autoboxed using Integer.valueOf(int).

Try this:

jquery

    $('#save-source').click(function (e) {
        e.preventDefault();
        var source = {
            'ID': 0,
            //'ProductID': $('#ID').val(),
            'PartNumber': $('#part-number').val(),
            //'VendorID': $('#Vendors').val()
        }
        $.ajax({
            type: "POST",
            dataType: "json",
            url: "/api/PartSourceAPI",
            data: source,
            success: function (data) {
                alert(data);
            },
            error: function (error) {
                jsonValue = jQuery.parseJSON(error.responseText);
                //jError('An error has occurred while saving the new part source: ' + jsonValue, { TimeShown: 3000 });
            }
        });
    });

Controller

    public string Post(PartSourceModel model)
    {
        return model.PartNumber;
    }

View

<label>Part Number</label>
<input type="text" id="part-number" name="part-number" />

<input type="submit" id="save-source" name="save-source" value="Add" />

Now when you click 'Add' after you fill out the text box, the controller will spit back out what you wrote in the PartNumber box in an alert.

This may work if you can call a batch file (I use php with XP sp2 and IE8... you can try IE7, dunno). Use the following (or similar) in your .bat file to open Windows: Start ""C:\Progra~1\Intern~1\iexplore "http://www.site.com". There is no space between the quotation mark and C:\Progr... etc. At some point, this may begin to open new windows (i.e., target="_blank") rather than new tabs, but works up to a point; not extensively tested. To use this in a regular batch file (CMD.exe), you probably need to have a window already open. Just sharing something I stumbled across. EDITED for clarification.

Here is a non-numpy solution:

>>> a = [[40, 10], [50, 11]]
>>> [float(sum(l))/len(l) for l in zip(*a)]
[45.0, 10.5]

If you removed the make all line from your "fresh" target:

fresh :
    rm -f *.o $(EXEC)
    clear

You could simply run the command make fresh all, which will execute as make fresh; make all.

Some might consider this as a second instance of make, but it's certainly not a sub-instance of make (a make inside of a make), which is what your attempt seemed to result in.

UPDATE January, 2017:

According to Can I use, the user-select is currently supported in all browsers except Internet Explorer 9 and earlier versions (but sadly still needs a vendor prefix).

All of the correct CSS variations are:

.noselect {_x000D_
  -webkit-touch-callout: none; /* iOS Safari */_x000D_
    -webkit-user-select: none; /* Safari */_x000D_
     -khtml-user-select: none; /* Konqueror HTML */_x000D_
       -moz-user-select: none; /* Firefox */_x000D_
        -ms-user-select: none; /* Internet Explorer/Edge */_x000D_
            user-select: none; /* Non-prefixed version, currently_x000D_
                                  supported by Chrome and Opera */_x000D_
}

<p>_x000D_
  Selectable text._x000D_
</p>_x000D_
<p class="noselect">_x000D_
  Unselectable text._x000D_
</p>

Note that it's a non-standard feature (i.e. not a part of any specification). It is not guaranteed to work everywhere, and there might be differences in implementation among browsers and in the future browsers can drop support for it.

More information can be found in Mozilla Developer Network documentation.

You should look into Video For Everyone:

Video for Everybody is very simply a chunk of HTML code that embeds a video into a website using the HTML5 element which offers native playback in Firefox 3.5 and Safari 3 & 4 and an increasing number of other browsers.

The video is played by the browser itself. It loads quickly and doesn’t threaten to crash your browser.

In other browsers that do not support , it falls back to QuickTime.

If QuickTime is not installed, Adobe Flash is used. You can host locally or embed any Flash file, such as a YouTube video.

The only downside, is that you have to have 2/3 versions of the same video stored, but you can serve to every existing device/browser that supports video (i.e.: the iPhone).

<video width="640" height="360" poster="__POSTER__.jpg" controls="controls">

What about

now()::timestamp

If your other timestamp are without time zone then this cast will yield the matching type "timestamp without time zone" for the current time.

I would like to read what others think about that option, though. I still don't trust in my understanding of this "with/without" time zone stuff.

EDIT: Adding Michael Ekoka's comment here because it clarifies an important point:

Caveat. The question is about generating default timestamp in UTC for a timestamp column that happens to not store the time zone (perhaps because there's no need to store the time zone if you know that all your timestamps share the same). What your solution does is to generate a local timestamp (which for most people will not necessarily be set to UTC) and store it as a naive timestamp (one that does not specify its time zone).

C# has a lot of reference types. Even if a container stores the references contiguously, the objects themselves may be scattered through the heap

var array = [[1, "grape", 42], [2, "fruit", 9]];

array.sort(function(a, b)
{
    // a and b will here be two objects from the array
    // thus a[1] and b[1] will equal the names

    // if they are equal, return 0 (no sorting)
    if (a[1] == b[1]) { return 0; }
    if (a[1] > b[1])
    {
        // if a should come after b, return 1
        return 1;
    }
    else
    {
        // if b should come after a, return -1
        return -1;
    }
});

The sort function takes an additional argument, a function that takes two arguments. This function should return -1, 0 or 1 depending on which of the two arguments should come first in the sorting. More info.

I also fixed a syntax error in your multidimensional array.

First of all need to understand what is CSV and how to write it.

(Most of answers (all of them at the moment) do not use this requirements, that's why they all is wrong!)

1. Every next string ( /r/n ) is next "table" row.
2. "Table" cells is separated by some delimiter symbol.
3. As delimiter can be used ANY symbol. Often this is \t or ,.
4. Each cell possibly can contain this delimiter symbol inside of the cell (cell must to start with double quotes symbol and to have double quote in the end in this case)
5. Each cell possibly can contains /r/n symbols inside of the cell (cell must to start with double quotes symbol and to have double quote in the end in this case)

Some time ago I had wrote simple class for CSV read/write based on standard Microsoft.VisualBasic.FileIO library. Using this simple class you will be able to work with CSV like with 2 dimensions array.

Simple example of using my library:

Csv csv = new Csv("\t");//delimiter symbol

csv.FileOpen("c:\\file1.csv");

var row1Cell6Value = csv.Rows[0][5];

csv.AddRow("asdf","asdffffff","5")

csv.FileSave("c:\\file2.csv");

You can find my class by the following link and investigate how it's written: https://github.com/ukushu/DataExporter

This library code is really fast in work and source code is really short.

PS: In the same time this solution will not work for unity.

PS2: Another solution is to work with library "LINQ-to-CSV". It must also work well. But it's will be bigger.

A li doesn't have a value. Only form-related elements such as input, textarea and select have values.

First set path of python https://stackoverflow.com/questions/3701646/how-to-add-to-the-pythonpath-in-windows

and run python file

python filename.py

command line argument with python

python filename.py command-line argument

For SQL Server 2005+

;WITH T AS
(
SELECT *, 
       COUNT(*) OVER (PARTITION BY Lastname) as Cnt
FROM Students
)
SELECT * /*TODO: Add column list. Don't use "*"                   */
FROM T
WHERE Cnt >= 3

numbers = [1, 2, 3]
numsum = sum(list(numbers))
print(numsum)

This would work, if your are trying to Sum up a list.

That should fit your needs:

var yourComponent = React.createClass({
    render: function () {
        return (
            <View style={{flex:1, flexDirection:'column', justifyContent:'center'}}>
                <View style={{flexDirection:'row'}}>
                    <TextInput style={{flex:0.8, borderWidth:1, height:20}}></TextInput>
                    <View style={{flex:0.2}}></View> // spacer
                </View>
            </View>
        );
    }
});

Verify it on SQL Server:

Select top 10 * From emp 
EXCEPT
Select top 9 * From emp

This will give you 10th ROW of emp table!

Common approach

There is option for tar program:

-I, --use-compress-program PROG
      filter through PROG (must accept -d)

You can use multithread version of archiver or compressor utility.

Most popular multithread archivers are pigz (instead of gzip) and pbzip2 (instead of bzip2). For instance:

$ tar -I pbzip2 -cf OUTPUT_FILE.tar.bz2 paths_to_archive
$ tar --use-compress-program=pigz -cf OUTPUT_FILE.tar.gz paths_to_archive

Archiver must accept -d. If your replacement utility hasn't this parameter and/or you need specify additional parameters, then use pipes (add parameters if necessary):

$ tar cf - paths_to_archive | pbzip2 > OUTPUT_FILE.tar.gz
$ tar cf - paths_to_archive | pigz > OUTPUT_FILE.tar.gz

Input and output of singlethread and multithread are compatible. You can compress using multithread version and decompress using singlethread version and vice versa.

p7zip

For p7zip for compression you need a small shell script like the following:

#!/bin/sh
case $1 in
  -d) 7za -txz -si -so e;;
   *) 7za -txz -si -so a .;;
esac 2>/dev/null

Save it as 7zhelper.sh. Here the example of usage:

$ tar -I 7zhelper.sh -cf OUTPUT_FILE.tar.7z paths_to_archive
$ tar -I 7zhelper.sh -xf OUTPUT_FILE.tar.7z

xz

Regarding multithreaded XZ support. If you are running version 5.2.0 or above of XZ Utils, you can utilize multiple cores for compression by setting -T or --threads to an appropriate value via the environmental variable XZ_DEFAULTS (e.g. XZ_DEFAULTS="-T 0").

This is a fragment of man for 5.1.0alpha version:

Multithreaded compression and decompression are not implemented yet, so this option has no effect for now.

However this will not work for decompression of files that haven't also been compressed with threading enabled. From man for version 5.2.2:

Threaded decompression hasn't been implemented yet. It will only work on files that contain multiple blocks with size information in block headers. All files compressed in multi-threaded mode meet this condition, but files compressed in single-threaded mode don't even if --block-size=size is used.

Recompiling with replacement

If you build tar from sources, then you can recompile with parameters

--with-gzip=pigz
--with-bzip2=lbzip2
--with-lzip=plzip

After recompiling tar with these options you can check the output of tar's help:

$ tar --help | grep "lbzip2\|plzip\|pigz"
  -j, --bzip2                filter the archive through lbzip2
      --lzip                 filter the archive through plzip
  -z, --gzip, --gunzip, --ungzip   filter the archive through pigz

Strings are immutable, meaning their contents cannot change. When you call replace(this,that) you end up with a totally new String. If you want to keep this new copy, you need to assign it to a variable. You can overwrite the old reference (a la sentence = sentence.replace(this,that) or a new reference as seen below:

public class Test{

    public static void main(String[] args) {

        String sentence = "Define, Measure, Analyze, Design and Verify";

        String replaced = sentence.replace("and", "");
        System.out.println(replaced);

    }
}

As an aside, note that I've removed the contains() check, as it is an unnecessary call here. If it didn't contain it, the replace will just fail to make any replacements. You'd only want that contains method if what you're replacing was different than the actual condition you're checking.

You're walking on uncharted territory here. Here is the Go example for calling C code, perhaps you can do something like that after reading up on C++ name mangling and calling conventions, and lots of trial and error.

If you still feel like trying it, good luck.

My usecase is:

1. Navigate to webapp.
2. Webapp detects I am not logged in, and redirects to an SSO site - different server!
3. SSO site (maybe on Jenkins) detects I am not logged into AD, and shows a login popup.
4. After you enter credentials, you are redirected back to webapp.

I am on later versions of Selenium 3, and the login popup is not detected with driver.switchTo().alert(); - results in NoAlertPresentException.

Just providing username:password in the URL is not propagated from step 1 to 2 above.

My workaround:

import org.apache.http.client.utils.URIBuilder;

driver.get(...webapp_location...);
wait.until(ExpectedConditions.urlContains(...sso_server...));

URIBuilder uri = null;
try {
    uri = new URIBuilder(driver.getCurrentUrl());
} catch (URISyntaxException ex) {
    ex.printStackTrace();
}
uri.setUserInfo(username, password);
driver.navigate().to(uri.toString());

I have a rotating image using the same thing as you:

.knoop1 img{
    position:absolute;
    width:114px;
    height:114px;
    top:400px;
    margin:0 auto;
    margin-left:-195px;
    z-index:0;

    -webkit-transition-duration: 0.8s;
    -moz-transition-duration: 0.8s;
    -o-transition-duration: 0.8s;
    transition-duration: 0.8s;

    -webkit-transition-property: -webkit-transform;
    -moz-transition-property: -moz-transform;
    -o-transition-property: -o-transform;
     transition-property: transform;

     overflow:hidden;
}

.knoop1:hover img{
    -webkit-transform:rotate(360deg);
    -moz-transform:rotate(360deg); 
    -o-transform:rotate(360deg);
}

If you have an unsorted vector, then you can simply swap with the last vector element then resize().

With an ordered container, you'll be best off with ?std::vector::erase(). Note that there is a std::remove() defined in <algorithm>, but that doesn't actually do the erasing. (Read the documentation carefully).

for me DATENAME was not accessable due to company restrictions.... but this worked very easy too.

I faced similar issue when the SDK tools installation was failed during the initial setup. To resolution is to download SDK tools from Android Developer Site

• Expand "USE AN EXISTING IDE" section and download standalone SDK tools
• Choose your destination as (%HOMEPATH%\android-sdks)
• Now start Android-SDKs folder and run SDK manager

There are two common ways of doing that with built-in JSON serializers:

1. JavaScriptSerializer

   var serializer = new JavaScriptSerializer();
   return serializer.Serialize(TheList);
   

2. DataContractJsonSerializer

   var serializer = new DataContractJsonSerializer(TheList.GetType());
   using (var stream = new MemoryStream())
   {
       serializer.WriteObject(stream, TheList);
       using (var sr = new StreamReader(stream))
       {
           return sr.ReadToEnd();
       }
   }
   

   Note, that this option requires definition of a data contract for your class:

   [DataContract]
   public class MyObjectInJson
   {
      [DataMember]
      public long ObjectID {get;set;}
      [DataMember]
      public string ObjectInJson {get;set;}
   }
   

Question?

Looking at the answers and the question, it seems the question has been modified significantly. So to answer the current question:

Convert LocalDateTime to LocalDateTime in UTC.

Timezone?

LocalDateTime does not store any information about the time-zone, it just basically holds the values of year, month, day, hour, minute, second, and smaller units. So an important question is: What is the timezone of the original LocalDateTime? It might as well be UTC already, therefore no conversion has to be made.

System Default Timezone

Considering that you asked the question anyway, you probably meant that the original time is in your system-default timezone and you want to convert it to UTC. Because usually a LocalDateTime object is created by using LocalDateTime.now() which returns the current time in the system-default timezone. In this case, the conversion would be the following:

LocalDateTime convertToUtc(LocalDateTime time) {
    return time.atZone(ZoneId.systemDefault()).withZoneSameInstant(ZoneOffset.UTC).toLocalDateTime();
}

An example of the conversion process:

2019-02-25 11:39 // [time] original LocalDateTime without a timezone
2019-02-25 11:39 GMT+1 // [atZone] converted to ZonedDateTime (system timezone is Madrid)
2019-02-25 10:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2019-02-25 10:39 // [toLocalDateTime] losing the timezone information

Explicit Timezone

In any other case, when you explicitly specify the timezone of the time to convert, the conversion would be the following:

LocalDateTime convertToUtc(LocalDateTime time, ZoneId zone) {
    return time.atZone(zone).withZoneSameInstant(ZoneOffset.UTC).toLocalDateTime();
}

An example of the conversion process:

2019-02-25 11:39 // [time] original LocalDateTime without a timezone
2019-02-25 11:39 GMT+2 // [atZone] converted to ZonedDateTime (zone is Europe/Tallinn)
2019-02-25 09:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2019-02-25 09:39 // [toLocalDateTime] losing the timezone information

The atZone() Method

The result of the atZone() method depends on the time passed as its argument, because it considers all the rules of the timezone, including Daylight Saving Time (DST). In the examples, the time was 25th February, in Europe this means winter time (no DST).

If we were to use a different date, let's say 25th August from last year, the result would be different, considering DST:

2018-08-25 11:39 // [time] original LocalDateTime without a timezone
2018-08-25 11:39 GMT+3 // [atZone] converted to ZonedDateTime (zone is Europe/Tallinn)
2018-08-25 08:39 GMT // [withZoneSameInstant] converted to UTC, still as ZonedDateTime
2018-08-25 08:39 // [toLocalDateTime] losing the timezone information

The GMT time does not change. Therefore the offsets in the other timezones are adjusted. In this example, the summer time of Estonia is GMT+3, and winter time GMT+2.

Also, if you specify a time within the transition of changing clocks back one hour. E.g. October 28th, 2018 03:30 for Estonia, this can mean two different times:

2018-10-28 03:30 GMT+3 // summer time [UTC 2018-10-28 00:30]
2018-10-28 04:00 GMT+3 // clocks are turned back 1 hour [UTC 2018-10-28 01:00]
2018-10-28 03:00 GMT+2 // same as above [UTC 2018-10-28 01:00]
2018-10-28 03:30 GMT+2 // winter time [UTC 2018-10-28 01:30]

Without specifying the offset manually (GMT+2 or GMT+3), the time 03:30 for the timezone Europe/Tallinn can mean two different UTC times, and two different offsets.

Summary

As you can see, the end result depends on the timezone of the time passed as an argument. Because the timezone cannot be extracted from the LocalDateTime object, you have to know yourself which timezone it is coming from in order to convert it to UTC.

Note that openpyxl does not have a large toolbox for manipulating and editing images. Xlsxwriter has methods for images, but on the other hand cannot import existing worksheets...

I have found that this works for rows... I'm sure there's a way to do it for columns...

import openpyxl

oxl = openpyxl.load_workbook('File Loction Here')
xl = oxl.['SheetName']

x=0
col = "A"
row = x

while (row <= 100):
    y = str(row)
    cell = col + row
    xl[cell] = x
    row = row + 1
    x = x + 1

1) Create a .gitignore file. To do that, you just create a .txt file and change the extension as follows:

Then you have to change the name, writing the following line in a cmd window:

 rename git.txt .gitignore

Where git.txt is the name of the file you've just created.

Then you can open the file and write all the files you don’t want to add on the repository. For example, mine looks like this:

#OS junk files
[Tt]humbs.db
*.DS_Store

#Visual Studio files
*.[Oo]bj
*.user
*.aps
*.pch
*.vspscc
*.vssscc
*_i.c
*_p.c
*.ncb
*.suo
*.tlb
*.tlh
*.bak
*.[Cc]ache
*.ilk
*.log
*.lib
*.sbr
*.sdf
*.pyc
*.xml
ipch/
obj/
[Bb]in
[Dd]ebug*/
[Rr]elease*/
Ankh.NoLoad

#Tooling
_ReSharper*/
*.resharper
[Tt]est[Rr]esult*

#Project files
[Bb]uild/

#Subversion files
.svn

# Office Temp Files
~$*

Once you have this, you need to add it to your Git repository. You have to save the file where your repository is.

Then in Git Bash you have to write the following line:

git config --global core.excludesfile ~/.gitignore_global

If the repository already exists then you have to do the following:

1. git rm -r --cached .
2. git add .
3. git commit -m ".gitignore is now working"

If the step 2 doesn’t work then you should write the whole route of the files that you would like to add.

Iterate through strings characters and use functions of 'Char' called 'IsLetter' and 'IsDigit'.

If you need something more specific - use Regex class.

The answer to your question is yes and no, depending on what you mean by "inline function". If you're using the term like it's used in C++ development then the answer is no, you can't do that - even a lambda expression is a function call. While it's true that you can define inline lambda expressions to replace function declarations in C#, the compiler still ends up creating an anonymous function.

Here's some really simple code I used to test this (VS2015):

    static void Main(string[] args)
    {
        Func<int, int> incr = a => a + 1;
        Console.WriteLine($"P1 = {incr(5)}");
    }

What does the compiler generate? I used a nifty tool called ILSpy that shows the actual IL assembly generated. Have a look (I've omitted a lot of class setup stuff)

This is the Main function:

        IL_001f: stloc.0
        IL_0020: ldstr "P1 = {0}"
        IL_0025: ldloc.0
        IL_0026: ldc.i4.5
        IL_0027: callvirt instance !1 class [mscorlib]System.Func`2<int32, int32>::Invoke(!0)
        IL_002c: box [mscorlib]System.Int32
        IL_0031: call string [mscorlib]System.String::Format(string, object)
        IL_0036: call void [mscorlib]System.Console::WriteLine(string)
        IL_003b: ret

See those lines IL_0026 and IL_0027? Those two instructions load the number 5 and call a function. Then IL_0031 and IL_0036 format and print the result.

And here's the function called:

        .method assembly hidebysig 
            instance int32 '<Main>b__0_0' (
                int32 a
            ) cil managed 
        {
            // Method begins at RVA 0x20ac
            // Code size 4 (0x4)
            .maxstack 8

            IL_0000: ldarg.1
            IL_0001: ldc.i4.1
            IL_0002: add
            IL_0003: ret
        } // end of method '<>c'::'<Main>b__0_0'

It's a really short function, but it is a function.

Is this worth any effort to optimize? Nah. Maybe if you're calling it thousands of times a second, but if performance is that important then you should consider calling native code written in C/C++ to do the work.

In my experience readability and maintainability are almost always more important than optimizing for a few microseconds gain in speed. Use functions to make your code readable and to control variable scoping and don't worry about performance.

for iterating through JSON you can use this:

json_object = json.loads(json_file)
for element in json_object: 
    for value in json_object['Name_OF_YOUR_KEY/ELEMENT']:
        print(json_object['Name_OF_YOUR_KEY/ELEMENT']['INDEX_OF_VALUE']['VALUE'])

The solution given by Sandman and Praveen is very well. The only problem with that if you have categorical variables in other columns of your data frame this method will need some adjustments.

My solution to this type of issue is following:

 from sklearn import preprocesing
 x = pd.concat([df.Numerical1, df.Numerical2,df.Numerical3])
 min_max_scaler = preprocessing.MinMaxScaler()
 x_scaled = min_max_scaler.fit_transform(x)
 x_new = pd.DataFrame(x_scaled)
 df = pd.concat([df.Categoricals,x_new])

Scanner's buffer full when we take a input string through scan.nextLine(); so it skips the input next time . So solution is that we can create a new object of Scanner , the name of the object can be same as previous object......

In the case of integers that are included at the string, if you want to avoid casting them to int individually you can do:

mList = [int(e) if e.isdigit() else e for e in mStr.split(',')]

It is called list comprehension, and it is based on set builder notation.

ex:

>>> mStr = "1,A,B,3,4"
>>> mList = [int(e) if e.isdigit() else e for e in mStr.split(',')]
>>> mList
>>> [1,'A','B',3,4]
