I have found this better way , no need to remove data , just call the source of the remote content each time

$(document).ready(function() {
    $('.class').click(function() {
        var id = this.id;
        //alert(id);checking that have correct id
        $("#iframe").attr("src","url?id=" + id);
        $('#Modal').modal({ 
            show: true 
        });
    });
});

Just use .animate() instead of .css() (with a duration if you want), like this:

$('#hfont1').hover(function() {
    $(this).animate({"color":"#efbe5c","font-size":"52pt"}, 1000);
}, function() {
    $(this).animate({"color":"#e8a010","font-size":"48pt"}, 1000);
});

You can test it here. Note though, you need either the jQuery color plugin, or jQuery UI included to animate the color. In the above, the duration is 1000ms, you can change it, or just leave it off for the default 400ms duration.

import javax.swing.JOptionPane;
import javax.swing.JFrame;

/*Some piece of code*/
frame.addWindowListener(new java.awt.event.WindowAdapter() {
    @Override
    public void windowClosing(java.awt.event.WindowEvent windowEvent) {
        if (JOptionPane.showConfirmDialog(frame, 
            "Are you sure you want to close this window?", "Close Window?", 
            JOptionPane.YES_NO_OPTION,
            JOptionPane.QUESTION_MESSAGE) == JOptionPane.YES_OPTION){
            System.exit(0);
        }
    }
});

If you also want to prevent the window from closing unless the user chooses 'Yes', you can add:

frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

You can disable ReSharper 5 and newer versions by using the Suspend button in menu Tools -> Options -> ReSharper.

I have not used BeuatifulSoup but maybe the following can help in some tiny way.

import re
import urllib2
stuff = urllib2.urlopen(your_url_goes_here).read()  # stuff will contain the *entire* page

# Replace the string Python with your desired regex
results = re.findall('(Python)',stuff)

for i in results:
    print i

I'm not suggesting this is a replacement but maybe you can glean some value in the concept until a direct answer comes along.

This is based on what GeekyMonkey posted above, with some modifications.

There's a native DOM API that achieves this out of the box — getBoundingClientRect:

document.querySelector("#whatever").getBoundingClientRect().right

The Chapter object should have reference to the book it came from so I would suggest something like chapter.getBook().getTitle();

Your database table structure should have a books table and a chapters table with columns like:

books

• id
• book specific info
• etc

chapters

• id
• book_id
• chapter specific info
• etc

Then to reduce the number of queries use a join table in your search query.

I had exactly the same problem with you. And after two days wondering why this occurs to me, I finally got through this by moving the adb.exe from the unreliable software list of the COMODO anti-virus to its reliable software list. At that time, I had tried at least 5 kinds of measures to make the adb work, including all above...

This worked for me On Windows 10,

xcopy /s {source drive..i.e. C:} {destination drive..i.e. D:} This will copy all the files and folders plus the folder contents.

Add this rule to your .htaccess

Header add Access-Control-Allow-Origin "*" 

even better, as suggested by @david thomas, you can use a specific domain value, e.g.

Header add Access-Control-Allow-Origin "your-domain.com"

You are dropping it, then creating it, then trying to create it again by using SELECT INTO. Change to:

DROP TABLE #TMPGUARDIAN
CREATE TABLE #TMPGUARDIAN(
LAST_NAME NVARCHAR(30),
FRST_NAME NVARCHAR(30))  

INSERT INTO #TMPGUARDIAN 
SELECT LAST_NAME,FRST_NAME  
FROM TBL_PEOPLE

In MS SQL Server you can create a table without a CREATE TABLE statement by using SELECT INTO

For an automatic letterbox/pillarbox in a fixed-size rectangle, use the object-fit CSS property. That is usually what I want, and it avoids using code to figure out which is the dominant dimension or — what I used to do — embedding an <SVG> element with an <image> child to wrap the content with its nice preserveAspectRatio options.

Just call this.finish() before startActivity(intent) like this-

       Intent intent = new Intent(ActivityOne.this, ActivityTwo.class);
        this.finish();
        startActivity(intent);

I would add that one can also use xampp, mamp type of things and put your project in the htdocs folder so it is accessible on localhost

The most decent way in my opinion is ``.

i = 32   -->    `i` == '32'

long millis = durationInMillis % 1000;
long second = (durationInMillis / 1000) % 60;
long minute = (durationInMillis / (1000 * 60)) % 60;
long hour = (durationInMillis / (1000 * 60 * 60)) % 24;

String time = String.format("%02d:%02d:%02d.%d", hour, minute, second, millis);

use this method instead:

function getCookie(name) {
    var value = "; " + document.cookie;
    var parts = value.split("; " + name + "=");
    if (parts.length == 2) return parts.pop().split(";").shift();
    else return null;
}

function doSomething() {
    var myCookie = getCookie("MyCookie");

    if (myCookie == null) {
        // do cookie doesn't exist stuff;
    }
    else {
        // do cookie exists stuff
    }
}

That file has a listen-port element - that should be what you need to change, although it is currently set to 8080, not 7001.

I had already faced this issue. In my case below code is correct.

Objective C

[textField setValue:[UIColor whiteColor] forKeyPath:@"_placeholderLabel.textColor"];

For Swift 4.X

tf_mobile.setValue(UIColor.white, forKeyPath: "_placeholderLabel.textColor")

For iOS 13 Swift Code

tf_mobile.attributedPlaceholder = NSAttributedString(string:"PlaceHolder Text", attributes: [NSAttributedString.Key.foregroundColor: UIColor.red])

You can also use below code for iOS 13

let iVar = class_getInstanceVariable(UITextField.self, "_placeholderLabel")!
let placeholderLabel = object_getIvar(tf_mobile, iVar) as! UILabel
placeholderLabel.textColor = .red

Hope, this may help you.

It's not clear exactly what you want to do with the index of a substring [update: it is clearer now - thanks] but you may be able to use the function substring-after or substring-before:

substring-before('My name is Fred', 'Fred')

returns 'My name is '.

If you need more detailed control, the substring() function can take two or three arguments: string, starting-index, length. Omit length to get the whole rest of the string.

There is no index-of() function for strings in XPath (only for sequences, in XPath 2.0). You can use string-length(substring-before($string, $substring))+1 if you specifically need the position.

There is also contains($string, $substring). These are all documented here. In XPath 2.0 you can use regular expression matching.

(XSLT mostly uses XPath for selecting nodes and processing values, so this is actually more of an XPath question. I tagged it thus.)

Expanding the #down child to fill the remaining space of #container can be accomplished in various ways depending on the browser support you wish to achieve and whether or not #up has a defined height.

Grid

CSS's grid layout offers yet another option, though it may not be as straightforward as the Flexbox model. However, it only requires styling the container element:

.container { display: grid; grid-template-rows: 100px }

The grid-template-rows defines the first row as a fixed 100px height, and the remain rows will automatically stretch to fill the remaining space.

I'm pretty sure IE11 requires -ms- prefixes, so make sure to validate the functionality in the browsers you wish to support.

Flexbox

CSS3's Flexible Box Layout Module (flexbox) is now well-supported and can be very easy to implement. Because it is flexible, it even works when #up does not have a defined height.

#container { display: flex; flex-direction: column; }
#down { flex-grow: 1; }

It's important to note that IE10 & IE11 support for some flexbox properties can be buggy, and IE9 or below has no support at all.

Calculated Height

Another easy solution is to use the CSS3 calc functional unit, as Alvaro points out in his answer, but it requires the height of the first child to be a known value:

#up { height: 100px; }
#down { height: calc( 100% - 100px ); }

It is pretty widely supported, with the only notable exceptions being <= IE8 or Safari 5 (no support) and IE9 (partial support). Some other issues include using calc in conjunction with transform or box-shadow, so be sure to test in multiple browsers if that is of concern to you.

Other Alternatives

If older support is needed, you could add height:100%; to #down will make the pink div full height, with one caveat. It will cause overflow for the container, because #up is pushing it down.

Therefore, you could add overflow: hidden; to the container to fix that.

Alternatively, if the height of #up is fixed, you could position it absolutely within the container, and add a padding-top to #down.

And, yet another option would be to use a table display:

#container { width: 300px; height: 300px; border: 1px solid red; display: table;}
#up { background: green; display: table-row; height: 0; }
#down { background: pink; display: table-row;}?

studentType newStudent() // studentType doesn't exist here
{   
    struct studentType // it only exists within the function
    {
        string studentID;
        string firstName;
        string lastName;
        string subjectName;
        string courseGrade;

        int arrayMarks[4];

        double avgMarks;

    } newStudent;
...

Move it outside the function:

struct studentType
{
    string studentID;
    string firstName;
    string lastName;
    string subjectName;
    string courseGrade;

    int arrayMarks[4];

    double avgMarks;

};

studentType newStudent()
{
    studentType newStudent
    ...
    return newStudent;
}

Pure CSS only for nav tabs, very simple for small screens:

@media (max-width: 767px) {
     .nav-tabs {
         min-width: 100%;
         display: inline-grid;
     }
}

You say it works once you install the VB6 IDE so the problem is likely to be that the components you are trying to use depend on the VB6 runtime being installed.

The VB6 runtime isn't installed on Windows by default.

Installing the IDE is one way to get the runtime. For non-developer machines, a "redistributable" installer package from Microsoft should be used instead.

Here is one VB6 runtime installer from Microsoft. I'm not sure if it will be the right version for your components:

I have just sent an email with gmail through Python. Try to use smtplib.SMTP_SSL to make the connection. Also, you may try to change the gmail domain and port.

So, you may get a chance with:

server = smtplib.SMTP_SSL('smtp.googlemail.com', 465)
server.login(gmail_user, password)
server.sendmail(gmail_user, TO, BODY)

As a plus, you could check the email builtin module. In this way, you can improve the readability of you your code and handle emails headers easily.

Be sure to check Xcode Preferences -> Locations.

The Command Line Tools I had selected was for the previous version of Xcode (8.2.1 instead of 10.1)

At last I fixed it simply using:

display: table;

There is no difference. Both will work in the same way.

CSS background properties are used to define the background effects of an element.

CSS properties used for background effects:

• background-color
• background-image
• background-repeat
• background-attachment
• background-position

Background property includes all of this properties and you can just write them in one line.

Set colspan to your number of columns, and background color as you wish

<tr style="background: #aaa;">
 <td colspan="2"></td>
</tr>

  SELECT t1.a, t2.b
  FROM t1
  JOIN t2 ON t1.a LIKE '%'+t2.b +'%'

because the last answer not work

Use Timer for this

   private System.Windows.Forms.Timer timer1; 
   private int counter = 60;
   private void btnStart_Click_1(object sender, EventArgs e)
   {
        timer1 = new System.Windows.Forms.Timer();
        timer1.Tick += new EventHandler(timer1_Tick);
        timer1.Interval = 1000; // 1 second
        timer1.Start();
        lblCountDown.Text = counter.ToString();
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        counter--;
        if (counter == 0)
            timer1.Stop();
        lblCountDown.Text = counter.ToString();
    }

So it would become:

List<Integer> myCoords = new ArrayList<Integer>();
myCoords.add(10);
myCoords.add(20);
myCoords.add(30);
myCoords.add(40);
myCoords.add(50);
while(true)
    Iterator<Integer> myListIterator = myCoords.iterator(); 
    while (myListIterator.hasNext()) {
        Integer coord = myListIterator.next();    
        System.out.print("\r" + coord);
        try{
    Thread.sleep(2000);
  }catch(Exception e){
   // handle the exception...
  }
    }
}

Installing a 64-bit version of Java will solve the issue. Go to page Java Downloads for All Operating Systems

This is a problem due to the incompatibility of the Java version and the Eclipse version both should be 64 bit if you are using a 64-bit system.

Here is a more reliable version:

class D(object):
    def __init__(self):
        self.test = 20
        self.test2 = 21
    def __getattribute__(self, name):
        if name == 'test':
            return 0.
        else:
            return super(D, self).__getattribute__(name)

It calls __getattribute__ method from parent class, eventually falling back to object.__getattribute__ method if other ancestors don't override it.

Just wanted to point out two things that seem inaccurate or at least confusing:

Always persist time according to a unified standard that is not affected by daylight savings. GMT and UTC have been mentioned by different people, though UTC seems to be mentioned most often.

For (almost) all practical computing purposes, UTC is, in fact, GMT. Unless you see a timestamps with a fractional second, you're dealing with GMT which makes this distinction redundant.

Include the local time offset as is (including DST offset) when storing timestamps.

A timestamp is always represented in GMT and thus has no offset.

Remove annotation type configuration like @Service from the thread run method.

@Service, @Component

Another option to get two digit minutes or hours.

var date = new Date("2012-01-18T16:03");

var minutes = date.toTimeString().slice(3, 5); 
var hours   = date.toTimeString().slice(0, 2); 

This is the syntax to import class

  <%@ page import="package.class" %>

It is worth mentioning that there is also: database scoped global temporary tables(currently supported only by Azure SQL Database).

Global temporary tables for SQL Server (initiated with ## table name) are stored in tempdb and shared among all users’ sessions across the whole SQL Server instance.

Azure SQL Database supports global temporary tables that are also stored in tempdb and scoped to the database level. This means that global temporary tables are shared for all users’ sessions within the same Azure SQL Database. User sessions from other databases cannot access global temporary tables.

-- Session A creates a global temp table ##test in Azure SQL Database testdb1
-- and adds 1 row
CREATE TABLE ##test ( a int, b int);
INSERT INTO ##test values (1,1);

-- Session B connects to Azure SQL Database testdb1 
-- and can access table ##test created by session A
SELECT * FROM ##test
---Results
1,1

-- Session C connects to another database in Azure SQL Database testdb2 
-- and wants to access ##test created in testdb1.
-- This select fails due to the database scope for the global temp tables 
SELECT * FROM ##test
---Results
Msg 208, Level 16, State 0, Line 1
Invalid object name '##test'

ALTER DATABASE SCOPED CONFIGURATION

GLOBAL_TEMPORARY_TABLE_AUTODROP = { ON | OFF }

APPLIES TO: Azure SQL Database (feature is in public preview)

Allows setting the auto-drop functionality for global temporary tables. The default is ON, which means that the global temporary tables are automatically dropped when not in use by any session. When set to OFF, global temporary tables need to be explicitly dropped using a DROP TABLE statement or will be automatically dropped on server restart.

With Azure SQL Database single databases and elastic pools, this option can be set in the individual user databases of the SQL Database server. In SQL Server and Azure SQL Database managed instance, this option is set in TempDB and the setting of the individual user databases has no effect.

tl;dr

LocalDate.now()       // Capture the date-only value current in the JVM’s current default time zone.
         .getYear()   // Extract the year number from that date.

2018

java.time

Both the java.util.Date and java.util.Calendar classes are legacy, now supplanted by the java.time framework built into Java 8 and later.

A time zone is crucial in determining a date. For any given moment, the date varies around the globe by zone. For example, a few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

If no time zone is specified, the JVM implicitly applies its current default time zone. That default may change at any moment, so your results may vary. Better to specify your desired/expected time zone explicitly as an argument.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "Africa/Tunis" ) ;  

If you want only the date without time-of-day, use LocalDate. This class lacks time zone info but you can specify a time zone to determine the current date.

ZoneId zoneId = ZoneId.of( "America/Montreal" );
LocalDate localDate = LocalDate.now( zoneId );

You can get the various pieces of information with getYear, getMonth, and getDayOfMonth. You will actually get the year number with java.time!

int year = localDate.getYear();

2016

If you want a date-time instead of just a date, use ZonedDateTime class.

ZonedDateTime zdt = ZonedDateTime.now( zoneId ) ;

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations.

Much of the java.time functionality is back-ported to Java 6 & Java 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP (see How to use…).

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

If you set CURLOPT_RETURNTRANSFER to true or 1 then the return value from curl_exec will be the actual result from the successful operation. In other words it will not return TRUE on success. Although it will return FALSE on failure.

As described in the Return Values section of curl-exec PHP manual page: http://php.net/manual/function.curl-exec.php

You should enable the CURLOPT_FOLLOWLOCATION option for redirects but this would be a problem if your server is in safe_mode and/or open_basedir is in effect which can cause issues with curl as well.

Try to install the missing module.

There is a Bearer type specified in the Authorization header for use with OAuth bearer tokens (meaning the client app simply has to present ("bear") the token). The value of the header is the access token the client received from the Authorization Server.

It's documented in this spec: https://tools.ietf.org/html/rfc6750#section-2.1

E.g.:

   GET /resource HTTP/1.1
   Host: server.example.com
   Authorization: Bearer mF_9.B5f-4.1JqM

Where mF_9.B5f-4.1JqM is your OAuth access token.

I have found a very easy solution! If you have a form and you want to have a custom submit button you can use some code like this:

<button type="submit">
    <img src="login.png" onmouseover="this.src='login2.png';" onmouseout="this.src='login.png';" />
</button>

Or just direct it to a link of a page.

If you want the text within the list items to be centred, try:

ul#menu-utility-navigation {
  width: 100%;
}

ul#menu-utility-navigation li {
  text-align: center;
}

To increase the font size of netbeans 7.3.1 and 7.3 , you go from menu Tools>>Options>>"Fonts & Colors" (is an inner menu in the dialog window of Options)

At the "Syntax" tab ,every entry in the "Category:" list-box ,you will notice that the font has the value "Inherited". If you find in the "Category" list-box the entry with the name "Default" and change the font value of that, you will affect the font size of your editor, because everything is inherited from "Default" entry .

Another method is to increase temporary the font of the editor by a combination of keys. To find what are the keys go to the "Options" dialog window by Tools>> Options and then choose the "Keymap" menu entry and then in the "Search" textbox type "zoom text" and it will show you what combinations of keys for zooming in /out.

for example mine is the combination of "alt" key + mouse wheel up/down

Do not use on iOS 9. This returns nil for all strings passed through it.

I have found another solution that allows you to update the language strings, w/o restarting the app and compatible with genstrings:

Put this macro in the Prefix.pch:

#define currentLanguageBundle [NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:[[NSLocale preferredLanguages] objectAtIndex:0] ofType:@"lproj"]]

and where ever you need a localized string use:

NSLocalizedStringFromTableInBundle(@"GalleryTitleKey", nil, currentLanguageBundle, @"")

To set the language use:

[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"de"] forKey:@"AppleLanguages"];

Works even with consecutive language hopping like:

NSLog(@"test %@", NSLocalizedStringFromTableInBundle(@"NewKey", nil, currentLanguageBundle, @""));
[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"fr"] forKey:@"AppleLanguages"];
NSLog(@"test %@", NSLocalizedStringFromTableInBundle(@"NewKey", nil, currentLanguageBundle, @""));
[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"it"] forKey:@"AppleLanguages"];
NSLog(@"test %@", NSLocalizedStringFromTableInBundle(@"NewKey", nil, currentLanguageBundle, @""));
[[NSUserDefaults standardUserDefaults] setObject:[NSArray arrayWithObject:@"de"] forKey:@"AppleLanguages"];
NSLog(@"test %@", NSLocalizedStringFromTableInBundle(@"NewKey", nil, currentLanguageBundle, @""));

• To update a single local package:

  1. First find out your outdated packages:

     npm outdated

  2. Then update the package or packages that you want manually as:

     npm update --save package_name

This way it is not necessary to update your local package.json file.

Note that this will update your package to the latest version.

• If you write some version in your package.json file and do:

  npm update package_name

  In this case you will get just the next stable version (wanted) regarding the version that you wrote in your package.json file.

And with npm list (package_name) you can find out the current version of your local packages.

Disabling Device Guard or Credential Guard fixed for me:

• click Start > Run, type gpedit.msc, and click Ok. The Local Group Policy Editor opens. Go to Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security. Select Disabled.
• Go to Control Panel > Uninstall a Program > Turn Windows features on or off to turn off Hyper-V.

Select. Do not restart.

Delete the related EFI variables by launching a command prompt on the host machine using an Administrator account and run these commands:

Use subprocess.check_output (new in python 2.7). It will suppress stdout and raise an exception if the command fails. (It actually returns the contents of stdout, so you can use that later in your program if you want.) Example:

import subprocess
try:
    subprocess.check_output(['espeak', text])
except subprocess.CalledProcessError:
    # Do something

You can also suppress stderr with:

    subprocess.check_output(["espeak", text], stderr=subprocess.STDOUT)

For earlier than 2.7, use

import os
import subprocess
with open(os.devnull, 'w')  as FNULL:
    try:
        subprocess._check_call(['espeak', text], stdout=FNULL)
    except subprocess.CalledProcessError:
        # Do something

Here, you can suppress stderr with

        subprocess._check_call(['espeak', text], stdout=FNULL, stderr=FNULL)

Unfortunately, I don't think Pandas allows one to drop dups off the indices. I would suggest the following:

df3 = df3.reset_index() # makes date column part of your data
df3.columns = ['timestamp','A','B','rownum'] # set names
df3 = df3.drop_duplicates('timestamp',take_last=True).set_index('timestamp') #done!

I needed this information too and got information with this method,

Launch PowerShell

run the 'import-module servermanager' command ( without quotes )

after that for asp.net 3.5 check run the 'get-windowsfeature web-asp-net' command ( without quotes )

for asp.net 4.5 check run the 'get-windowsfeature Net-Framework-45-Core' command ( without quotes )

Both of the commands will inform you below Install State header.

A possibility is that the git server you are pushing to is down/crashed, and the solution lies in restarting the git server.

The Selenium client bindings will try to locate the geckodriver executable from the system PATH. You will need to add the directory containing the executable to the system path.

• On Unix systems you can do the following to append it to your system’s search path, if you’re using a bash-compatible shell:

  export PATH=$PATH:/path/to/geckodriver
  

• On Windows you need to update the Path system variable to add the full directory path to the executable. The principle is the same as on Unix.

All below configuration for launching latest firefox using any programming language binding is applicable for Selenium2 to enable Marionette explicitly. With Selenium 3.0 and later, you shouldn't need to do anything to use Marionette, as it's enabled by default.

To use Marionette in your tests you will need to update your desired capabilities to use it.

Java :

As exception is clearly saying you need to download latest geckodriver.exe from here and set downloaded geckodriver.exe path where it's exists in your computer as system property with with variable webdriver.gecko.driver before initiating marionette driver and launching firefox as below :-

//if you didn't update the Path system variable to add the full directory path to the executable as above mentioned then doing this directly through code
System.setProperty("webdriver.gecko.driver", "path/to/geckodriver.exe");

//Now you can Initialize marionette driver to launch firefox
DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability("marionette", true);
WebDriver driver = new MarionetteDriver(capabilities); 

And for Selenium3 use as :-

WebDriver driver = new FirefoxDriver();

If you're still in trouble follow this link as well which would help you to solving your problem

.NET :

var driver = new FirefoxDriver(new FirefoxOptions());

Python :

from selenium import webdriver
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

# Path to Firefox DevEdition or Nightly.
# Firefox 47 (stable) is currently not supported,
# and may give you a suboptimal experience.
#
# On Mac OS you must point to the binary executable
# inside the application package, such as
# /Applications/FirefoxNightly.app/Contents/MacOS/firefox-bin
caps["binary"] = "/usr/bin/firefox"

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by directly passing marionette: true
# You might need to specify an alternate path for the desired version of Firefox

Selenium::WebDriver::Firefox::Binary.path = "/path/to/firefox"
driver = Selenium::WebDriver.for :firefox, marionette: true

JavaScript (Node.js) :

const webdriver = require('selenium-webdriver');
const Capabilities = require('selenium-webdriver/lib/capabilities').Capabilities;

var capabilities = Capabilities.firefox();

// Tell the Node.js bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.set('marionette', true);

var driver = new webdriver.Builder().withCapabilities(capabilities).build();

Using RemoteWebDriver

If you want to use RemoteWebDriver in any language, this will allow you to use Marionette in Selenium Grid.

Python:

caps = DesiredCapabilities.FIREFOX

# Tell the Python bindings to use Marionette.
# This will not be necessary in the future,
# when Selenium will auto-detect what remote end
# it is talking to.
caps["marionette"] = True

driver = webdriver.Firefox(capabilities=caps)

Ruby :

# Selenium 3 uses Marionette by default when firefox is specified
# Set Marionette in Selenium 2 by using the Capabilities class
# You might need to specify an alternate path for the desired version of Firefox

caps = Selenium::WebDriver::Remote::Capabilities.firefox marionette: true, firefox_binary: "/path/to/firefox"
driver = Selenium::WebDriver.for :remote, desired_capabilities: caps

Java :

DesiredCapabilities capabilities = DesiredCapabilities.firefox();

// Tell the Java bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.setCapability("marionette", true);

WebDriver driver = new RemoteWebDriver(capabilities); 

.NET

DesiredCapabilities capabilities = DesiredCapabilities.Firefox();

// Tell the .NET bindings to use Marionette.
// This will not be necessary in the future,
// when Selenium will auto-detect what remote end
// it is talking to.
capabilities.SetCapability("marionette", true);

var driver = new RemoteWebDriver(capabilities); 

Note : Just like the other drivers available to Selenium from other browser vendors, Mozilla has released now an executable that will run alongside the browser. Follow this for more details.

You can download latest geckodriver executable to support latest firefox from here

js> s = "http://www.example.com/string with + and ? and & and spaces";
http://www.example.com/string with + and ? and & and spaces
js> encodeURI(s)
http://www.example.com/string%20with%20+%20and%20?%20and%20&%20and%20spaces
js> encodeURIComponent(s)
http%3A%2F%2Fwww.example.com%2Fstring%20with%20%2B%20and%20%3F%20and%20%26%20and%20spaces

Looks like encodeURI produces a "safe" URI by encoding spaces and some other (e.g. nonprintable) characters, whereas encodeURIComponent additionally encodes the colon and slash and plus characters, and is meant to be used in query strings. The encoding of + and ? and & is of particular importance here, as these are special chars in query strings.

If you're using the ReSharper plugin, you can do that using the Shift + Alt + L shortcut or navigate via menu as shown.

^\+?\(?[0-9]{1,3}\)? ?-?[0-9]{1,3} ?-?[0-9]{3,5} ?-?[0-9]{4}( ?-?[0-9]{3})?

Check your cases here: https://regex101.com/r/DuYT9f/1

Select * 
FROM test_table 
WHERE user_id = value 
AND date_added = (select max(date_added) 
   from test_table 
   where user_id = value)

Use a keep alive.

On login:

session_start();
$_SESSION['last_action'] = time();

An ajax call every few (eg 20) seconds:

windows.setInterval(keepAliveCall, 20000);

Server side keepalive.php:

session_start();
$_SESSION['last_action'] = time();

On every other action:

session_start();
if ($_SESSION['last_action'] < time() - 30 /* be a little tolerant here */) {
  // destroy the session and quit
}

Using regexp: \S will match non whitespace character:anything but not a space, tab or new line. If your string has a single character which is not a space, tab or new line, then it's not empty. Therefore you just need to search for one character: \S

JavaScript:

function checkvalue() { 
    var mystring = document.getElementById('myString').value; 
    if(!mystring.match(/\S/)) {
        alert ('Empty value is not allowed');
        return false;
    } else {
        alert("correct input");
        return true;
    }
}

HTML:

<form onsubmit="return checkvalue(this)">
    <input name="myString" type="text" value='' id="myString">
    <input type="submit" value="check value" />
</form>

You can just make a System.Uri object, and use IsFile to verify it's a file, then Uri.LocalPath to extract the filename.

This is much safer, as it provides you a means to check the validity of the URI as well.

Edit in response to comment:

To get just the full filename, I'd use:

Uri uri = new Uri(hreflink);
if (uri.IsFile) {
    string filename = System.IO.Path.GetFileName(uri.LocalPath);
}

This does all of the error checking for you, and is platform-neutral. All of the special cases get handled for you quickly and easily.

You can put this in your .h file for your class and define it as property, in XCode 7:

@property int  (*stuffILike) [10];

I'm doing something very similar in a private project I'm working on. Thus far I've generated images up to 1024x1024 without any problems (except memory) and can display them very quickly and without any performance problems.

Overriding the paint method of JPanel subclass is overkill and requires more work than you need to do.

The way I do it is:

Class MapIcon implements Icon {...}

OR

Class MapIcon extends ImageIcon {...}

The code you use to generate the image will be in this class. I use a BufferedImage to draw onto then when the paintIcon() is called, use g.drawImvge(bufferedImage); This reduces the amount of flashing done while you generate your images, and you can thread it.

Next I extend JLabel:

Class MapLabel extends Scrollable, MouseMotionListener {...}

This is because I want to put my image on a scroll pane, I.e. display part of the image and have the user scroll around as needed.

So then I use a JScrollPane to hold the MapLabel, which contains only the MapIcon.

MapIcon map = new MapIcon (); 
MapLabel mapLabel = new MapLabel (map);
JScrollPane scrollPane = new JScrollPane();

scrollPane.getViewport ().add (mapLabel);

But for your scenario (just show the whole image every time). You need to add the MapLabel to the top JPanel, and make sure to size them all to the full size of the image (by overriding the GetPreferredSize()).

1. Right click ? copy ? copy element

For me the solution was to download the Android SDK and launch adb devices which started the adb daemon.

Think of 0 as false and 1 as true. Then bitwise and(&) and or(|) work just like regular and and or except they do all of the bits in the value at once. Typically you will see them used for flags if you have 30 options that can be set (say as draw styles on a window) you don't want to have to pass in 30 separate boolean values to set or unset each one so you use | to combine options into a single value and then you use & to check if each option is set. This style of flag passing is heavily used by OpenGL. Since each bit is a separate flag you get flag values on powers of two(aka numbers that have only one bit set) 1(2^0) 2(2^1) 4(2^2) 8(2^3) the power of two tells you which bit is set if the flag is on.

Also note 2 = 10 so x|2 is 110(6) not 111(7) If none of the bits overlap(which is true in this case) | acts like addition.

EDIT: Probably not the right way to do it, see comments

You could use sklearn.feature_selection.f_regression.

click here for the scikit-learn page

Simply:

LongOperation MyTask = new LongOperation();
MyTask.execute();

Every answer I've read indicates the SUBSYSTEM=="usb". However, my (perhaps ancient) udev needed this to be changed to DRIVER=="usb". At last I can run the adb server as a non-root user... yay.

It can be instructive to look at the output of udevmonitor --env, followed by the output of

udevinfo -a -p <DEVICE_PATH_AS_REPORTED_BY-udevmonitor>

According to official documentation https://keras.io/getting-started/faq/#how-can-i-install-hdf5-or-h5py-to-save-my-models-in-keras

you can do :

first test if you have h5py installed by running the

import h5py

if you dont have errors while importing h5py you are good to save:

from keras.models import load_model

model.save('my_model.h5')  # creates a HDF5 file 'my_model.h5'
del model  # deletes the existing model

# returns a compiled model
# identical to the previous one
model = load_model('my_model.h5')

If you need to install h5py http://docs.h5py.org/en/latest/build.html

If you want to map objects to something (in this case a property). I think Array.prototype.map is what you're looking for if you want to code functionally.

[
  {name: "Joe", age: 22},
  {name: "Kevin", age: 24},
  {name: "Peter", age: 21}
].map(function(elem){
    return elem.name;
}).join(",");

In modern JavaScript:

[
  {name: "Joe", age: 22},
  {name: "Kevin", age: 24},
  {name: "Peter", age: 21}
].map(e => e.name).join(",");

(fiddle)

If you want to support older browsers, that are not ES5 compliant you can shim it (there is a polyfill on the MDN page above). Another alternative would be to use underscorejs's pluck method:

var users = [
      {name: "Joe", age: 22},
      {name: "Kevin", age: 24},
      {name: "Peter", age: 21}
    ];
var result = _.pluck(users,'name').join(",")

Here is the simple solution with StreamEx

EntryStream.of(countByType).sortedBy(e -> e.getValue()).keys().toList();

note that at the beginning of the question, there is a typo mistake:

<action android:name="android.intent.action._BOOT_COMPLETED"/>

instead of :

<action android:name="android.intent.action.BOOT_COMPLETED"/>

one small "_" and all this trouble :)

First of all, it's important to know what you mean by "open an Excel file for reading and copy it to clipboard..."

This is very important because there are many ways you could do that depending just on what you intend to do. Let me explain:

1. If you want to read a set of data and copy that in the clipboard and you know the data format (e.g. column names), I suggest you use an OleDbConnection to open the file, this way you can treat the xls file content as a Database Table, so you can read data with SQL instruction and treat the data as you want.

2. If you want to do operations on the data with the Excel object model then open it in the way you began.

3. Some time it's possible to treat an xls file as a kind of csv file, there are tools like File Helpers which permit you to treat and open an xls file in a simple way by mapping a structure on an arbitrary object.

Another important point is in which Excel version the file is.

I have, unfortunately I say, a strong experience working with Office automation in all ways, even if bounded in concepts like Application Automation, Data Management and Plugins, and generally I suggest only as the last resort, to using Excel automation or Office automation to read data; just if there aren't better ways to accomplish that task.

Working with automation could be heavy in performance, in terms of resource cost, could involve in other issues related for example to security and more, and last but not at least, working with COM interop it's not so "free".. So my suggestion is think and analyze the situation within your needs and then take the better way.

Empty returns true if the var is not set. But isset returns true even if the var is not empty.

There's no way to initiate a file transfer back to/from local Windows from a SSH session opened in PuTTY window.

Though PuTTY supports connection-sharing.

While you still need to run a compatible file transfer client (pscp or psftp), no new login is required, it automatically (if enabled) makes use of an existing PuTTY session.

To enable the sharing see:
Sharing an SSH connection between PuTTY tools.

Even without connection-sharing, you can still use the psftp or pscp from Windows command line.

See How to use PSCP to copy file from Unix machine to Windows machine ...?

Note that the scp is OpenSSH program. It's primarily *nix program, but you can run it via Windows Subsystem for Linux or get a Windows build from Win32-OpenSSH (it is already built-in in the latest versions of Windows 10).

If you really want to download the files to a local desktop, you have to specify a target path as %USERPROFILE%\Desktop (what typically resolves to a path like C:\Users\username\Desktop).

Alternative way is to use WinSCP, a GUI SFTP/SCP client. While you browse the remote site, you can anytime open SSH terminal to the same site using Open in PuTTY command.
See Opening Session in PuTTY.

With an additional setup, you can even make PuTTY automatically navigate to the same directory you are browsing with WinSCP.
See Opening PuTTY in the same directory.

(I'm the author of WinSCP)

It is also possible to use the new button attribute called formtarget that was introduced with HTML5.

<form>
  <input type="submit" formtarget="_blank"/>
</form>

Before MySQL 5.7.6 this works from the command line:

mysql -e "SET PASSWORD FOR 'root'@'localhost' = PASSWORD('$w0rdf1sh');"

I don't have a mysql install to test on but I think in your case it would be

mysql -e "UPDATE mysql.user SET Password=PASSWORD('$w0rdf1sh') WHERE User='tate256';"

FIXED!

I've been wrestling with the same issue, and just had a breakthrough! We've established that if you give the image a background color or image, the png displays properly on top of it. The black border is gone, but now you've got an opaque background, and that pretty much defeats the purpose.

Then I remembered a rgba to ie filter converter I came across. (Thanks be to Michael Bester). So I wondered what would happen if I gave my problem pngs an ie filtered background emulating rgba(255,255,255,0), fully expecting it not to work, but lets try it anyway...

.item img {
    background: transparent;
    -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#00FFFFFF,endColorstr=#00FFFFFF)"; /* IE8 */   
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#00FFFFFF,endColorstr=#00FFFFFF);   /* IE6 & 7 */      
    zoom: 1;

}

Presto! Goodbye black, and hello working alpha channels in ie7 and 8. Fade your pngs in and out, or animate them across the screen - it's all good.

It's document.getElementById, not document.getElementsByID

I'm assuming you have <input id="Tue" ...> somewhere in your markup.

$(document).ready(function() {
    $(document).on("click", ".question", function(e) {
       var checked = $(this).find("input:checkbox").is(":checked");
       if (checked) {
           $('.answer').show(300);
       } else {
           $('.answer').hide(300);
       }
    });
});

Using numba module for speed up.

On big datasets (500k >) pd.cut can be quite slow for binning data.

I wrote my own function in numba with just in time compilation, which is roughly 16x faster:

from numba import njit

@njit
def cut(arr):
    bins = np.empty(arr.shape[0])
    for idx, x in enumerate(arr):
        if (x >= 0) & (x < 1):
            bins[idx] = 1
        elif (x >= 1) & (x < 5):
            bins[idx] = 2
        elif (x >= 5) & (x < 10):
            bins[idx] = 3
        elif (x >= 10) & (x < 25):
            bins[idx] = 4
        elif (x >= 25) & (x < 50):
            bins[idx] = 5
        elif (x >= 50) & (x < 100):
            bins[idx] = 6
        else:
            bins[idx] = 7

    return bins

cut(df['percentage'].to_numpy())

# array([5., 5., 7., 5.])

Optional: you can also map it to bins as strings:

a = cut(df['percentage'].to_numpy())

conversion_dict = {1: 'bin1',
                   2: 'bin2',
                   3: 'bin3',
                   4: 'bin4',
                   5: 'bin5',
                   6: 'bin6',
                   7: 'bin7'}

bins = list(map(conversion_dict.get, a))

# ['bin5', 'bin5', 'bin7', 'bin5']

Speed comparison:

# create dataframe of 8 million rows for testing
dfbig = pd.concat([df]*2000000, ignore_index=True)

dfbig.shape

# (8000000, 1)

%%timeit
cut(dfbig['percentage'].to_numpy())

# 38 ms ± 616 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

%%timeit
bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
pd.cut(dfbig['percentage'], bins=bins, labels=labels)

# 215 ms ± 9.76 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

If you get this error due to foreach and you really need to save one entity first inside loop and use generated identity further in loop, as was in my case, the easiest solution is to use another DBContext to insert entity which will return Id and use this Id in outer context

For example

    using (var context = new DatabaseContext())
    {
        ...
        using (var context1 = new DatabaseContext())
        {
            ...
               context1.SaveChanges();
        }                         
        //get id of inserted object from context1 and use is.   
      context.SaveChanges();
   }

You can always create an ArrayList of Objects. But it will not be very useful to you. Suppose you have created the Arraylist like this:

List<Object> myList = new ArrayList<Object>();

and add objects to this list like this:

myList.add(new Integer("5"));

myList.add("object");

myList.add(new Object());

You won't face any problem while adding and retrieving the object but it won't be very useful. You have to remember at what location each type of object is it in order to use it. In this case after retrieving, all you can do is calling the methods of Object on them.

I had a similar problem.

My Problem:

I want to calculate an SVD and need to sort my eigenvalues in descending order. But I want to keep the mapping between eigenvalues and eigenvectors. My eigenvalues were in the first row and the corresponding eigenvector below it in the same column.

So I want to sort a two-dimensional array column-wise by the first row in descending order.

My Solution

a = a[::, a[0,].argsort()[::-1]]

So how does this work?

a[0,] is just the first row I want to sort by.

Now I use argsort to get the order of indices.

I use [::-1] because I need descending order.

Lastly I use a[::, ...] to get a view with the columns in the right order.

One way to print your code is to push it to an online version control system like Github or Bitbucket. In your browser, navigate to the file and print it.

Doing it this way, you'll get syntax highlighting and version control.

You can need to pass in the string 'int64':

>>> import pandas as pd
>>> df = pd.DataFrame({'a': [1.0, 2.0]})  # some test dataframe

>>> df['a'].astype('int64')
0    1
1    2
Name: a, dtype: int64

There are some alternative ways to specify 64-bit integers:

>>> df['a'].astype('i8')      # integer with 8 bytes (64 bit)
0    1
1    2
Name: a, dtype: int64

>>> import numpy as np
>>> df['a'].astype(np.int64)  # native numpy 64 bit integer
0    1
1    2
Name: a, dtype: int64

Or use np.int64 directly on your column (but it returns a numpy.array):

>>> np.int64(df['a'])
array([1, 2], dtype=int64)

db.data.update({'name': 'zero'}, {'$set': {'value': NumberInt(0)}})

You can also use NumberLong.

For .net Core in GET method, you can do like this:

 StringValues value1;
 string DeviceId = string.Empty;

  if (Request.Headers.TryGetValue("param1", out value1))
      {
                DeviceId = value1.FirstOrDefault();
      }

About this, java declares that on Windows 10, Edge browser does not support plugins, so it will NOT run java. (see https://www.java.com/it/download/win10.jsp --> only visible with edge in win10) It also reports a notice: java is not officially supported yet in Windows 10. (see https://www.java.com/it/download/faq/win10_faq.xml)

My try is combined solution.

string = string.replace(',', '.').replace(/[^\d\.]/g, "").replace(/\./, "x").replace(/\./g, "").replace(/x/, ".");
string = Math.round( parseFloat(string) * 100) / 100;

First line solution from here: regex replacing multiple periods in floating number . It replaces comma "," with dot "." ; Replaces first comma with x; Removes all dots and replaces x back to dot.

Second line cleans numbers after dot.

Well I just pulled up the Wikipedia page on it too, and in the intro portion I saw "Unicode can be implemented by different character encodings. The most commonly used encodings are UTF-8 (which uses one byte for any ASCII characters, which have the same code values in both UTF-8 and ASCII encoding, and up to four bytes for other characters), the now-obsolete UCS-2 (which uses two bytes for each character but cannot encode every character in the current Unicode standard)"

As this quote demonstrates, your problem is that you are assuming Unicode is a single way of encoding characters. There are actually multiple forms of Unicode, and, again in that quote, one of them even has 1 byte per character just like what you are used to.

So your simple answer that you want is that it varies.

To delete the last element from the list just do this.

a = [1,2,3,4,5]
a = a[:-1]
#Output [1,2,3,4] 

Do you have multiple Radio Buttons on the page..

Because what I see is that you are assigning the events to all the radio button's on the page when you click on a radio button

It is indeed much less simple than it seems :-) Nick's suggestion is a good one.

To get started, keep in mind that any worthwhile comparison method will essentially work by converting the images into a different form -- a form which makes it easier to pick similar features out. Usually, this stuff doesn't make for very light reading ...


One of the simplest examples I can think of is simply using the color space of each image. If two images have highly similar color distributions, then you can be reasonably sure that they show the same thing. At least, you can have enough certainty to flag it, or do more testing. Comparing images in color space will also resist things such as rotation, scaling, and some cropping. It won't, of course, resist heavy modification of the image or heavy recoloring (and even a simple hue shift will be somewhat tricky).

http://en.wikipedia.org/wiki/RGB_color_space
http://upvector.com/index.php?section=tutorials&subsection=tutorials/colorspace

Another example involves something called the Hough Transform. This transform essentially decomposes an image into a set of lines. You can then take some of the 'strongest' lines in each image and see if they line up. You can do some extra work to try and compensate for rotation and scaling too -- and in this case, since comparing a few lines is MUCH less computational work than doing the same to entire images -- it won't be so bad.

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.

in older bash (or in sh) that does not support declare -A, following style can be used to emulate key/value

# key
env=staging


# values
image_dev=gcr.io/abc/dev
image_staging=gcr.io/abc/stage
image_production=gcr.io/abc/stable

img_var_name=image_$env

# active_image=${!var_name}
active_image=$(eval "echo \$$img_var_name")

echo $active_image

Django also has the 'latest(field_name = None)' function that finds the latest (max. value) entry. It not only works with date fields but also with strings and integers.

You can give the field name when calling that function:

max_rated_entry = YourModel.objects.latest('rating')
return max_rated_entry.details

Or you can already give that field name in your models meta data:

from django.db import models

class YourModel(models.Model):
    #your class definition
    class Meta:
        get_latest_by = 'rating'

Now you can call 'latest()' without any parameters:

max_rated_entry = YourModel.objects.latest()
return max_rated_entry.details

Your tables should have as immediate children just tbody and thead elements, with the rows within*. So, amend the HTML to be:

<table border="1" width="100%" id="test">
  <tbody>
    <tr>
     <td>
      <table border="1" width="100%">
        <tbody>
          <tr>
            <td>table 2</td>
          </tr>
        </tbody>
      </table>
     </td>
    </tr> 
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
  </tbody>
</table>

Then amend your selector slightly to this:

#test > tbody > tr:last-child { background:#ff0000; }

See it in action here. That makes use of the child selector, which:

...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.

So, you are targeting only direct children of tbody elements that are themselves direct children of your #test table.

Alternative solution

The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:

#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }

* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:

...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.

Now someone told me that this is not very good programming because I use the return statement inside a loop and this would cause garbage collection to malfunction.

That's incorrect, and suggests you should treat other advice from that person with a degree of skepticism.

The mantra of "only have one return statement" (or more generally, only one exit point) is important in languages where you have to manage all resources yourself - that way you can make sure you put all your cleanup code in one place.

It's much less useful in Java: as soon as you know that you should return (and what the return value should be), just return. That way it's simpler to read - you don't have to take in any of the rest of the method to work out what else is going to happen (other than finally blocks).

one liner to download latest maven artifact without mvn:

curl -O -J -L  "https://repository.sonatype.org/service/local/artifact/maven/content?r=central-proxy&g=io.staticcdn.sdk&a=staticcdn-sdk-standalone-optimizer&e=zip&v=LATEST"

The $? syntax is pretty neat:

if [ $?BLAH == 1 ]; then 
    echo "Exists"; 
else 
    echo "Does not exist";

If you are mocking the behavior (with something like doNothing()) there should really be no need to call to verify*(). That said, here's my stab at re-writing your test method:

@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
   public void testProcessOrder() {
        //Variables
        InternalService is = new InternalService();
        Order order = mock(Order.class);

        //Mock Behavior
        when(order.isSuccessful()).thenReturn(true);
        mockStatic(Internalutils.class);
        doNothing().when(InternalUtils.class); //This is the preferred way
                                               //to mock static void methods.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

        //Execute
        is.processOrder(order);            

        //Verify
        verifyStatic(InternalUtils.class); //Similar to how you mock static methods
                                           //this is how you verify them.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
   }
}

I grouped into four sections to better highlight what is going on:

1. Variables

I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.

2. Mock Behavior

This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.

3. Execute

Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.

4. Verify

This is when you call any method starting with verify or assert. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.

Additional Notes

This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.

I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:

It is bad practice to perform network operations on the main thread, which is why you are seeing the NetworkOnMainThreadException. It is prevented by the policy. If you really must do it for testing, put the following in your OnCreate:

 StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
 StrictMode.setThreadPolicy(policy); 

Please remember that is is very bad practice to do this, and should ideally move your network code to an AsyncTask or a Thread.

$('#select').val('defaultValue'); 
$('#select').change();

This will also trigger events hooked to this select

Is there a name to describe this idiom?

In UML it is called aggregation. It differs from composition in that the member object is not owned by the referring class. In C++ you can implement aggregation in two different ways, through references or pointers.

I am assuming it is to prevent the possibly large overhead of copying a big complex object?

No, that would be a really bad reason to use this. The main reason for aggregation is that the contained object is not owned by the containing object and thus their lifetimes are not bound. In particular the referenced object lifetime must outlive the referring one. It might have been created much earlier and might live beyond the end of the lifetime of the container. Besides that, the state of the referenced object is not controlled by the class, but can change externally. If the reference is not const, then the class can change the state of an object that lives outside of it.

Is this generally good practice? Are there any pitfalls to this approach?

It is a design tool. In some cases it will be a good idea, in some it won't. The most common pitfall is that the lifetime of the object holding the reference must never exceed the lifetime of the referenced object. If the enclosing object uses the reference after the referenced object was destroyed, you will have undefined behavior. In general it is better to prefer composition to aggregation, but if you need it, it is as good a tool as any other.

You need to add the tomcat dependency in your pom

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>

You can do it in two ways:

First:

render() {
    const data =[{"name":"test1"},{"name":"test2"}];
    const listItems = data.map((d) => <li key={d.name}>{d.name}</li>);

    return (
      <div>
      {listItems }
      </div>
    );
  }

Second: Directly write the map function in the return

render() {
    const data =[{"name":"test1"},{"name":"test2"}];
    return (
      <div>
      {data.map(function(d, idx){
         return (<li key={idx}>{d.name}</li>)
       })}
      </div>
    );
  }

You can designate a button as the "AcceptButton" in the Form's properties and that will catch any "Enter" keypresses on the form and route them to that control.

See How to: Designate a Windows Forms Button as the Accept Button Using the Designer and note the few exceptions it outlines (multi-line text-boxes, etc.)

You ask two questions; your title says "Displaying a vector of strings", but you're not actually doing that, you actually build a single string composed of all the strings and output that.

Your question body asks "Why doesn't this work".

It doesn't work because your for loop is constrained by "userString.size()" which is 0, and you test your loop variable for being "userString.size() - 1". The condition of a for() loop is tested before permitting execution of the first iteration.

int n = 1;
for (int i = 1; i < n; ++i) {
    std::cout << i << endl;
}

will print exactly nothing.

So your loop executes exactly no iterations, leaving userString and sentence empty.

Lastly, your code has absolutely zero reason to use a vector. The fact that you used "decltype(userString.size())" instead of "size_t" or "auto", while claiming to be a rookie, suggests you're either reading a book from back to front or you are setting yourself up to fail a class.

So to answer your question at the end of your post: It doesn't work because you didn't step through it with a debugger and inspect the values as it went. While I say it tongue-in-cheek, I'm going to leave it out there.

Another way you can achieve the desired effect is to use this Material Search View library. It handles search history automatically and it's possible to provide search suggestions to the view as well.

Sample: (It's shown in Portuguese, but it also works in english and italian).

Setup

Before you can use this lib, you have to implement a class named MsvAuthority inside the br.com.mauker package on your app module, and it should have a public static String variable called CONTENT_AUTHORITY. Give it the value you want and don't forget to add the same name on your manifest file. The lib will use this file to set the Content Provider authority.

Example:

MsvAuthority.java

package br.com.mauker;

public class MsvAuthority {
    public static final String CONTENT_AUTHORITY = "br.com.mauker.materialsearchview.searchhistorydatabase";
}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>

    <application ... >
        <provider
        android:name="br.com.mauker.materialsearchview.db.HistoryProvider"
        android:authorities="br.com.mauker.materialsearchview.searchhistorydatabase"
        android:exported="false"
        android:protectionLevel="signature"
        android:syncable="true"/>
    </application>

</manifest>

Usage

To use it, add the dependency:

compile 'br.com.mauker.materialsearchview:materialsearchview:1.2.0'

And then, on your Activity layout file, add the following:

<br.com.mauker.materialsearchview.MaterialSearchView
    android:id="@+id/search_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

After that, you'll just need to get the MaterialSearchView reference by using getViewById(), and open it up or close it using MaterialSearchView#openSearch() and MaterialSearchView#closeSearch().

P.S.: It's possible to open and close the view not only from the Toolbar. You can use the openSearch() method from basically any Button, such as a Floating Action Button.

// Inside onCreate()
MaterialSearchView searchView = (MaterialSearchView) findViewById(R.id.search_view);
Button bt = (Button) findViewById(R.id.button);

bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            searchView.openSearch();
        }
    });

You can also close the view using the back button, doing the following:

@Override
public void onBackPressed() {
    if (searchView.isOpen()) {
        // Close the search on the back button press.
        searchView.closeSearch();
    } else {
        super.onBackPressed();
    }
}

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

Can these forum ids be worked out in a pragmatic way? e.g. can you find these forums somehow - if that is the case you should do something like

Topic.all(:joins => "left join forums on (forums.id = topics.forum_id and some_condition)", :conditions => "forums.id is null")

Which would be more efficient than doing an SQL not in

Found the answer here - http://mytechead.wordpress.com/2014/01/30/android-create-a-file-and-write-to-external-storage/

   // get the state of your external storage
   String state = Environment.getExternalStorageState();

    // if storage is mounted return true
      Log.v("sTag", "Yes, can write to external storage.");
      return true;
   }
   return false;
}

and then let’s use this code to actually write to the external storage:

// get the path to sdcard
File sdcard = Environment.getExternalStorageDirectory();
// to this path add a new directory path
File dir = new File(sdcard.getAbsolutePath() + "/your-dir-name/");
// create this directory if not already created
dir.mkdir();
// create the file in which we will write the contents
File file = new File(dir, "My-File-Name.txt");
FileOutputStream os = outStream = new FileOutputStream(file);
String data = "This is the content of my file";
os.write(data.getBytes());
os.close();

And this is it. If now you visit your /sdcard/your-dir-name/ folder you will see a file named - My-File-Name.txt with the content as specified in the code.

PS:- You need the following permission -

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

If you are using a MongoDB server then after using connect in the cluster clock on connect and finding the URL, the URL will be somehing like this

<mongodb+srv://Rohan:<password>@cluster0-3kcv6.mongodb.net/<dbname>?retryWrites=true&w=majority>

In this case, don't forget to replace the password with your database password and db name and then use

const client = new MongoClient(url,{useUnifiedTopology:true});

abs() is for integers only. For floating point, use fabs() (or one of the fabs() line with the correct precision for whatever a actually is)

To address why CMD is designed to run only one service per container, let's just realize what would happen if the secondary servers run in the same container are not trivial / auxiliary but "major" (e.g. storage bundled with the frontend app). For starters, it would break down several important containerization features such as horizontal (auto-)scaling and rescheduling between nodes, both of which assume there is only one application (source of CPU load) per container. Then there is the issue of vulnerabilities - more servers exposed in a container means more frequent patching of CVEs...

So let's admit that it is a 'nudge' from Docker (and Kubernetes/Openshift) designers towards good practices and we should not reinvent workarounds (SSH is not necessary - we have docker exec / kubectl exec / oc rsh designed to replace it).

These are the steps which i follows may be it is useful for you,

1. Go to menu-tools-database utilities-compact and repair database.

2. when repairing database delete or update that record.

3. it is working finely.

Take a look at class java.lang.Character static member methods (isDigit, isLetter, isLowerCase, ...)

Example:

String str = "Hello World 123 !!";
int specials = 0, digits = 0, letters = 0, spaces = 0;
for (int i = 0; i < str.length(); ++i) {
   char ch = str.charAt(i);
   if (!Character.isDigit(ch) && !Character.isLetter(ch) && !Character.isSpace(ch)) {
      ++specials;
   } else if (Character.isDigit(ch)) {
      ++digits;
   } else if (Character.isSpace(ch)) {
      ++spaces;
   } else {
      ++letters;
   }
}

Although I like using the keyboard module to capture keyboard events, I don't like its record() function because it returns an array like [KeyboardEvent("A"), KeyboardEvent("~")], which I find kind of hard to read. So, to record keyboard events, I like to use the keyboard module and the threading module simultaneously, like this:

import keyboard
import string
from threading import *


# I can't find a complete list of keyboard keys, so this will have to do:
keys = list(string.ascii_lowercase)
"""
Optional code(extra keys):

keys.append("space_bar")
keys.append("backspace")
keys.append("shift")
keys.append("esc")
"""
def listen(key):
    while True:
        keyboard.wait(key)
        print("[+] Pressed",key)
threads = [Thread(target=listen, kwargs={"key":key}) for key in keys]
for thread in threads:
    thread.start()

According to MDN History doc
There is clearly said that second argument is for future used not for now. You are right that second argument is deal with web-page title but currently it's ignored by all major browser.

Firefox currently ignores this parameter, although it may use it in the future. Passing the empty string here should be safe against future changes to the method. Alternatively, you could pass a short title for the state to which you're moving.

"The list are variables/paramaters that is pre-defined as comma separated lists". Do you mean that your query is actually

UPDATE tab1   SET budgpost_gr1=     
CASE  WHEN (budgpost in ('1001,1012,50055'))  THEN 'BP_GR_A'   
      WHEN (budgpost in ('5,10,98,0'))  THEN 'BP_GR_B'  
      WHEN (budgpost in ('11,876,7976,67465'))     
      ELSE 'Missing' END`

If so, you need a function to take a string and parse it into a list of numbers.

create type tab_num is table of number;

create or replace function f_str_to_nums (i_str in varchar2) return tab_num is
  v_tab_num tab_num := tab_num();
  v_start   number := 1;
  v_end     number;
  v_delim   VARCHAR2(1) := ',';
  v_cnt     number(1) := 1;
begin
  v_end := instr(i_str||v_delim,v_delim,1, v_start);
  WHILE v_end > 0 LOOP
    v_cnt := v_cnt + 1;
    v_tab_num.extend;
    v_tab_num(v_tab_num.count) := 
                  substr(i_str,v_start,v_end-v_start);
    v_start := v_end + 1;
    v_end := instr(i_str||v_delim,v_delim,v_start);
  END LOOP;
  RETURN v_tab_num;
end;
/

Then you can use the function like so:

select column_id, 
   case when column_id in 
     (select column_value from table(f_str_to_nums('1,2,3,4'))) then 'red' 
   else 'blue' end
from  user_tab_columns
where table_name = 'EMP'

Action is a delegate (pointer) to a method, that takes zero, one or more input parameters, but does not return anything.

Func is a delegate (pointer) to a method, that takes zero, one or more input parameters, and returns a value (or reference).

Predicate is a special kind of Func often used for comparisons.

Though widely used with Linq, Action and Func are concepts logically independent of Linq. C++ already contained the basic concept in form of typed function pointers.

Here is a small example for Action and Func without using Linq:

class Program
{
    static void Main(string[] args)
    {
        Action<int> myAction = new Action<int>(DoSomething);
        myAction(123);           // Prints out "123"
                                 // can be also called as myAction.Invoke(123);

        Func<int, double> myFunc = new Func<int, double>(CalculateSomething);
        Console.WriteLine(myFunc(5));   // Prints out "2.5"
    }

    static void DoSomething(int i)
    {
        Console.WriteLine(i);
    }

    static double CalculateSomething(int i)
    {
        return (double)i/2;
    }
}

Here's how you remove all the whitespace from the beginning and end of a String.

(Example tested with Swift 2.0.)

let myString = "  \t\t  Let's trim all the whitespace  \n \t  \n  "
let trimmedString = myString.stringByTrimmingCharactersInSet(
    NSCharacterSet.whitespaceAndNewlineCharacterSet()
)
// Returns "Let's trim all the whitespace"

(Example tested with Swift 3+.)

let myString = "  \t\t  Let's trim all the whitespace  \n \t  \n  "
let trimmedString = myString.trimmingCharacters(in: .whitespacesAndNewlines)
// Returns "Let's trim all the whitespace"

This is intended behavior.

When you make an HTTP request, the server normally returns code 200 OK. If you set If-Modified-Since, the server may return 304 Not modified (and the response will not have the content). This is supposed to be your cue that the page has not been modified.

The authors of the class have foolishly decided that 304 should be treated as an error and throw an exception. Now you have to clean up after them by catching the exception every time you try to use If-Modified-Since.

In Excel, you can set a Range.NumberFormat to any string as you would find in the "Custom" format selection. Essentially, you have two choices:

1. General for no particular format.
2. A custom formatted string, like "$#,##0", to specify exactly what format you're using.

I have tried using the dependency without version tag and its worked fine for me.

<dependency>
    <groupId>com.oracle.ojdbc</groupId>
    <artifactId>ojdbc8</artifactId>
</dependency>

I threw this together so that you could do some querying on the results

Declare @dbName varchar(150)
set @dbName = '[YOURDATABASENAME]'

--Total machine connections
--SELECT  COUNT(dbid) as TotalConnections FROM sys.sysprocesses WHERE dbid > 0

--Available connections
DECLARE @SPWHO1 TABLE (DBName VARCHAR(1000) NULL, NoOfAvailableConnections VARCHAR(1000) NULL, LoginName VARCHAR(1000) NULL)
INSERT INTO @SPWHO1 
    SELECT db_name(dbid), count(dbid), loginame FROM sys.sysprocesses WHERE dbid > 0 GROUP BY dbid, loginame
SELECT * FROM @SPWHO1 WHERE DBName = @dbName

--Running connections
DECLARE @SPWHO2 TABLE (SPID VARCHAR(1000), [Status] VARCHAR(1000) NULL, [Login] VARCHAR(1000) NULL, HostName VARCHAR(1000) NULL, BlkBy VARCHAR(1000) NULL, DBName VARCHAR(1000) NULL, Command VARCHAR(1000) NULL, CPUTime VARCHAR(1000) NULL, DiskIO VARCHAR(1000) NULL, LastBatch VARCHAR(1000) NULL, ProgramName VARCHAR(1000) NULL, SPID2 VARCHAR(1000) NULL, Request VARCHAR(1000) NULL)

There is one method of Collection named retainAll but having some side effects for you reference

Retains only the elements in this list that are contained in the specified collection (optional operation). In other words, removes from this list all of its elements that are not contained in the specified collection.

true if this list changed as a result of the call

Its like

boolean b = list1.retainAll(list2);

Uninstall NPM and install it again.

As of February 27, 2014 npm no longer supports its self-signed certificates. http://blog.npmjs.org/post/78085451721/npms-self-signed-certificate-is-no-more

The link above suggests upgrading NPM using NPM. This also fails with SELF_SIGNED_CERT_IN_CHAIN...

What is the len of the equivalent nested list?

len([[2,3,1,0], [2,3,1,0], [3,2,1,1]])

With the more general concept of shape, numpy developers choose to implement __len__ as the first dimension. Python maps len(obj) onto obj.__len__.

X.shape returns a tuple, which does have a len - which is the number of dimensions, X.ndim. X.shape[i] selects the ith dimension (a straight forward application of tuple indexing).

I like to construct commands with echo and pipe them to the shell:

$ find dir -name \*~ | xargs echo rm
...
$ find dir -name \*~ | xargs echo rm | ksh -s

Why? Because it allows me to look at what's going to be done before I do it. That way if I have a horrible error (like removing my home directory), I can catch it before it happens. Obviously, this is most important for destructive or irrevocable actions.

Use ConstraintLayout. Here is an example that will center the view according to the width and height of the parent screen:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="#FF00FF"
        android:orientation="vertical"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintHeight_percent=".6"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintWidth_percent=".4"></LinearLayout>
</android.support.constraint.ConstraintLayout>

You might need to change your gradle to get the latest version of ConstraintLayout:

dependencies {
...
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
}

You must to download MySQLConnection NET from here.

Then you need add MySql.Data.DLL to MSVisualStudio like this:

1. Open menu project
2. Add
3. Reference
4. Browse to C:\Program Files (x86)\MySQL\MySQL Connector Net 8.0.12\Assemblies\v4.5.2
5. Add MySql.Data.dll

If you want to know more visit: enter link description here

To use in the code you must import the library:

using MySql.Data.MySqlClient;

An example with connectio to Mysql database (NO SSL MODE) by means of Click event:

using System;
using System.Windows;
using MySql.Data.MySqlClient;


namespace Deportes_WPF
{

public partial class Login : Window
{
    private MySqlConnection connection;
    private string server;
    private string database;
    private string user;
    private string password;
    private string port;
    private string connectionString;
    private string sslM;

    public Login()
    {
        InitializeComponent();

        server = "server_name";
        database = "database_name";
        user = "user_id";
        password = "password";
        port = "3306";
        sslM = "none";

        connectionString = String.Format("server={0};port={1};user id={2}; password={3}; database={4}; SslMode={5}", server, port, user, password, database, sslM);

        connection = new MySqlConnection(connectionString);
    }

    private void conexion()
    {
        try
        {
            connection.Open();

            MessageBox.Show("successful connection");

            connection.Close();
        }
        catch (MySqlException ex)
        {
            MessageBox.Show(ex.Message + connectionString);
        }
    }

    private void btn1_Click(object sender, RoutedEventArgs e)
    {
        conexion();
    }
  }

}

Its a good idea to stay away from parseInt and use Number and Math.round unless you need hex or octal. Both can use strings. Why stay away from it?

parseInt(0.001, 10)
0

parseInt(-0.0000000001, 10)
-1

parseInt(0.0000000001, 10)
1

parseInt(4000000000000000000000, 10)
4

It completly butchers really large or really small numbers. Oddly enough it works normally if these inputs are a string.

parseInt("-0.0000000001", 10)
0

parseInt("0.0000000001", 10)
0

parseInt("4000000000000000000000", 10)
4e+21

Instead of risking hard to find bugs with this and the other gotchas people mentioned, I would just avoid parseInt unless you need to parse something other than base 10. Number, Math.round, Math.foor, and .toFixed(0) can all do the same things parseInt can be used for without having these types of bugs.

If you really want or need to use parseInt for some of it's other qualities, never use it to convert floats to ints.

Try this, just an example:

u.UserTypeOptions = new SelectList(new[]
    {
        new { ID="1", Name="name1" },
        new { ID="2", Name="name2" },
        new { ID="3", Name="name3" },
    }, "ID", "Name", 1);

Or

u.UserTypeOptions = new SelectList(new List<SelectListItem>
    {
        new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
        new SelectListItem { Selected = false, Text = "Homeowner", Value = "2"},
        new SelectListItem { Selected = false, Text = "Contractor", Value = "3"},
    },"Value","Text");

You can increment the stack depth allowed - with this, deeper recursive calls will be possible, like this:

import sys
sys.setrecursionlimit(10000) # 10000 is an example, try with different values

... But I'd advise you to first try to optimize your code, for instance, using iteration instead of recursion.

you can use like these "txtpassword.PasswordChar = '•';"

the use location is ...

 namespace Library_Management_System
    {
        public partial class Login : Form
        {
            public Login()
            {
                InitializeComponent();
                txtpassword.PasswordChar = '•';

I find the easiest way to illustrate it is to look at some code. This getting started page on the NUnit site is a good introduction to the what and the how

http://www.nunit.org/index.php?p=quickStart&r=2.5

Is everything testable? Generally if it calculates something then yes. UI code is a whole other problem to deal with though, as simulating users clicking on buttons is tricky.

What should you test? I tend to write tests around the things I know are going to be tricky. Complicated state transitions, business critical calculations, that sort of thing. Generally I'm not too worried about testing basic input/output stuff, although the purists will doubtless say I'm wrong on that front and everything should be tested. Like so many other things, there is no right answer!

The easiest way is to use PyHive.

To install you'll need these libraries:

pip install sasl
pip install thrift
pip install thrift-sasl
pip install PyHive

After installation, you can connect to Hive like this:

from pyhive import hive
conn = hive.Connection(host="YOUR_HIVE_HOST", port=PORT, username="YOU")

Now that you have the hive connection, you have options how to use it. You can just straight-up query:

cursor = conn.cursor()
cursor.execute("SELECT cool_stuff FROM hive_table")
for result in cursor.fetchall():
  use_result(result)

...or to use the connection to make a Pandas dataframe:

import pandas as pd
df = pd.read_sql("SELECT cool_stuff FROM hive_table", conn)

I followed the solution above from Jonas and it worked well until I needed to add a second column. What I found is that when making the columns visible again Oracle does not necessarily set them visible in the order listed in the statement.

To demonstrate this follow Jonas' example above. As he showed, once the steps are complete the table is in the order that you'd expect. Things then break down when you add another column as shown below:

Example (continued from Jonas'):

Add another column which is to be inserted before column C.

ALTER TABLE t ADD (b2 INT);

Use the technique demonstrated above to move the newly added B2 column before column C.

ALTER TABLE t MODIFY (c INVISIBLE, d INVISIBLE, e INVISIBLE);
ALTER TABLE t MODIFY (c VISIBLE, d VISIBLE, e VISIBLE);

DESCRIBE t;

Name
----
A
B
B2
D
E
C

As shown above column C has moved to the end. It seems that the ALTER TABLE statement above processed the columns in the order D, E, C rather than in the order specified in the statement (perhaps in physical table order). To ensure that the column is placed where desired it is necessary to make the columns visible one by one in the desired order.

ALTER TABLE t MODIFY (c INVISIBLE, d INVISIBLE, e INVISIBLE);
ALTER TABLE t MODIFY c VISIBLE;
ALTER TABLE t MODIFY d VISIBLE;
ALTER TABLE t MODIFY e VISIBLE;

DESCRIBE t;

Name
----
A
B
B2
C
D
E

Here is the usage for this method:

>>> help(all_matching_cidrs)

Help on function all_matching_cidrs in module netaddr.ip:

all_matching_cidrs(ip, cidrs)
    Matches an IP address or subnet against a given sequence of IP addresses and subnets.

    @param ip: a single IP address or subnet.

    @param cidrs: a sequence of IP addresses and/or subnets.

    @return: all matching IPAddress and/or IPNetwork objects from the provided
    sequence, an empty list if there was no match.

Basically you provide an ip address as the first argument and a list of cidrs as the second argument. A list of hits are returned.

The Google Chrome cache directory $HOME/.cache/google-chrome/Default/Cache on Linux contains one file per cache entry named <16 char hex>_0 in "simple entry format":

• 20 Byte SimpleFileHeader
• key (i.e. the URI)
• payload (the raw file content i.e. the PDF in our case)
• SimpleFileEOF record
• HTTP headers
• SHA256 of the key (optional)
• SimpleFileEOF record

If you know the URI of the file you're looking for it should be easy to find. If not, a substring like the domain name, should help narrow it down. Search for URI in your cache like this:

fgrep -Rl '<URI>' $HOME/.cache/google-chrome/Default/Cache

Note: If you're not using the default Chrome profile, replace Default with the profile name, e.g. Profile 1.

You can include the branch to track when setting up remotes, to keep things working as you might expect:

git remote add --track master origin [email protected]:group/project.git   # git
git remote add --track master origin [email protected]:group/project.git   # git w/IP
git remote add --track master origin http://github.com/group/project.git   # http
git remote add --track master origin http://172.16.1.100/group/project.git # http w/IP
git remote add --track master origin /Volumes/Git/group/project/           # local
git remote add --track master origin G:/group/project/                     # local, Win

This keeps you from having to manually edit your git config or specify branch tracking manually.

There is an ongoing effort to standardize hyphenation in CSS3.

Some modern browsers, notably Safari and Firefox, already support this. Here is a good and up to date reference on browser support.

Once the CSS hyphenation gets implemented universally, that would be the best solution. In the meantime, I can recommend Hyphenator - a JS script that figures out how to hyphenate your text in the way most appropriate for a particular browser.

Hyphenator:

• relies on Franklin M. Liangs hyphenation algorithm, commonly known from LaTeX and OpenOffice.
• uses CSS3 hyphenation where it is available,
• automatically inserts ­ on most other browsers,
• supports multiple languages,
• is highly configurable,
• gracefully falls back in case javascript is not enabled.

I've used it and it works great!

This is more general than .NET and Windows. Managed is an environment where you have automatic memory management, garbage collection, type safety, ... unmanaged is everything else. So for example .NET is a managed environment and C/C++ is unmanaged.

There are a number of ways of achieving your result. If you're just wanting a solution for your case, use string multiplication as @Ant mentions. This is only going to work if each of your print statements prints the same string. Note that it works for multiplication of any length string (e.g. 'foo' * 20 works).

>>> print 'a' * 20
aaaaaaaaaaaaaaaaaaaa

If you want to do this in general, build up a string and then print it once. This will consume a bit of memory for the string, but only make a single call to print. Note that string concatenation using += is now linear in the size of the string you're concatenating so this will be fast.

>>> for i in xrange(20):
...     s += 'a'
... 
>>> print s
aaaaaaaaaaaaaaaaaaaa

Or you can do it more directly using sys.stdout.write(), which print is a wrapper around. This will write only the raw string you give it, without any formatting. Note that no newline is printed even at the end of the 20 as.

>>> import sys
>>> for i in xrange(20):
...     sys.stdout.write('a')
... 
aaaaaaaaaaaaaaaaaaaa>>> 

Python 3 changes the print statement into a print() function, which allows you to set an end parameter. You can use it in >=2.6 by importing from __future__. I'd avoid this in any serious 2.x code though, as it will be a little confusing for those who have never used 3.x. However, it should give you a taste of some of the goodness 3.x brings.

>>> from __future__ import print_function
>>> for i in xrange(20):
...     print('a', end='')
... 
aaaaaaaaaaaaaaaaaaaa>>> 

I solve such queries using this pattern:

SELECT *
FROM t
WHERE t.field=(
  SELECT MAX(t.field) 
  FROM t AS t0 
  WHERE t.group_column1=t0.group_column1
    AND t.group_column2=t0.group_column2 ...)

That is it will select records where the value of a field is at its max value. To apply it to your query I used the common table expression so that I don't have to repeat the JOIN twice:

WITH site_history AS (
  SELECT sites.siteName, sites.siteIP, history.date
  FROM sites
  JOIN history USING (siteName)
)
SELECT *
FROM site_history h
WHERE date=(
  SELECT MAX(date) 
  FROM site_history h0 
  WHERE h.siteName=h0.siteName)
ORDER BY siteName

It's important to note that it works only if the field we're calculating the maximum for is unique. In your example the date field should be unique for each siteName, that is if the IP can't be changed multiple times per millisecond. In my experience this is commonly the case otherwise you don't know which record is the newest anyway. If the history table has an unique index for (site, date), this query is also very fast, index range scan on the history table scanning just the first item can be used.

webRequest.ContentType = "application/x-www-form-urlencoded";

1. Where does application/x-www-form-urlencoded's name come from?

   If you send HTTP GET request, you can use query parameters as follows:

   http://example.com/path/to/page?name=ferret&color=purple

   The content of the fields is encoded as a query string. The application/x-www-form- urlencoded's name come from the previous url query parameter but the query parameters is in where the body of request instead of url.

   The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character

   e.g. field1=value1&field2=value2

2. It can be simple request called simple - don't trigger a preflight check

   Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests

   • application/x-www-form-urlencoded
   • multipart/form-data
   • text/plain

3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.

request.ContentType = "application/json; charset=utf-8";

1. The data will be json format.

axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.

{
  "id": 1,
  "name": "Foo",
  "price": 123,
  "tags": [
    "Bar",
    "Eek"
  ],
  "stock": {
    "warehouse": 300,
    "retail": 20
  }
}

2. "application/json" Content-Type is one of the Preflighted requests.

Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.

3. application/json is beginner-friendly. URL encoded arrays can be a nightmare!

Yes it's a little tricky in TypeScript but you can do the below example like this

let decodeData  =  JSON.parse(`${jsonResponse}`);

Some googling reveals that potentially you've got a corrupt file:

http://bitterolives.blogspot.com/2009/03/excel-interop-comexception-hresult.html

and that you can tell excel to open it anyway with the CorruptLoad parameter, with something like...

Workbook workbook = excelApplicationObject.Workbooks.Open(path, CorruptLoad: true);

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

Date/Time Functions and Operators

slices to the rescue :)

def left(s, amount):
    return s[:amount]

def right(s, amount):
    return s[-amount:]

def mid(s, offset, amount):
    return s[offset:offset+amount]

As Jakub Vrána (The creator or Adminer and NotORM) mentions in the comments, to select the current timezone offset in TIME use:

SELECT TIMEDIFF(NOW(), UTC_TIMESTAMP);

It will return: 02:00:00 if your timezone is +2:00 for that date

I made a cheatsheet here: Should MySQL have its timezone set to UTC?

First off, it's not JSON: JSON mandates that all keys must be strings.

Secondly, regular arrays do what you want:

var Game = {
  status: [
    [
      "val",
      "val",
      "val"
    ],
    [
      "val",
      "val",
      "val"
    ]
  }

will work, if you use Game.status[0][0]. You cannot use numbers with the dot notation (.0).

Alternatively, you can quote the numbers (i.e. { "0": "val" }...); you will have plain objects instead of Arrays, but the same syntax will work.

I had the same issue... installed STS but consistently got the "java was started but returned exit code=13" message. My issue was that I was using the default install file, which was not processor specific, from https://spring.io/tools/sts. I had to dive deeper to be very specific in downloading the 64 bit version. It was not intuitive as to which version you were downloading. Once I got the 64 bit version (note that the zip file still includes 'win32' in the name, just appends '-64' at end) it worked.

Case 1 should have worked. I don't see anything wrong. There may be some other problems. I would suggest a clean build.

This is what I did with Angular 9. I'm not sure does this works in older versions.

You will need to call this when you need to reload.

 this.router.navigate([], {
    skipLocationChange: true,
    queryParamsHandling: 'merge' //== if you need to keep queryParams
  })

Router forRoot needs to have SameUrlNavigation set to 'reload'

 RouterModule.forRoot(appRoutes, {
  // ..
  onSameUrlNavigation: 'reload',
  // ..
})

And your every route needs to have runGuardsAndResolvers set to 'always'

{
    path: '',
    data: {},
    runGuardsAndResolvers: 'always'
},

To be thorough and remove lines even if they include spaces or tabs something like this in perl will do it:

cat file.txt | perl -lane "print if /\S/"

Of course there are the awk and sed equivalents. Best not to assume the lines are totally blank as ^$ would do.

Cheers

In your Model set:

protected $dates = ['name_field'];

after in your view :

{{ $user->from_date->format('d/m/Y') }}

works

char firstLetter = someString.charAt(0);
String oneLetter = String.valueOf(someChar);

You find the documentation by identifying the classes likely to be involved. Here, candidates are java.lang.String and java.lang.Character.

You should start by familiarizing yourself with:

• Primitive wrappers in java.lang
• Java Collection framework in java.util

It also helps to get introduced to the API more slowly through tutorials.

• Manipulating characters in a String

Some numpy functions for how to control the rounding: rint, floor,trunc, ceil. depending how u wish to round the floats, up, down, or to the nearest int.

>>> x = np.array([[1.0,2.3],[1.3,2.9]])
>>> x
array([[ 1. ,  2.3],
       [ 1.3,  2.9]])
>>> y = np.trunc(x)
>>> y
array([[ 1.,  2.],
       [ 1.,  2.]])
>>> z = np.ceil(x)
>>> z
array([[ 1.,  3.],
       [ 2.,  3.]])
>>> t = np.floor(x)
>>> t
array([[ 1.,  2.],
       [ 1.,  2.]])
>>> a = np.rint(x)
>>> a
array([[ 1.,  2.],
       [ 1.,  3.]])

To make one of this in to int, or one of the other types in numpy, astype (as answered by BrenBern):

a.astype(int)
array([[1, 2],
       [1, 3]])

>>> y.astype(int)
array([[1, 2],
       [1, 2]])

default clean command did not work for me giving following error:

$ slack-cleaner --token=<TOKEN> --message --channel <CHANNEL>

Running slack-cleaner v0.2.4
Channel, direct message or private group not found

but following worked without any issue to clean the bot messages

slack-cleaner --token <TOKEN> --message --group <CHANNEL> --bot --perform --rate 1 

or

slack-cleaner --token <TOKEN> --message --group <CHANNEL> --user "*" --perform --rate 1 

to clean all the messages.

I use rate-limit of 1 second to avoid HTTP 429 Too Many Requests error because of slack api rate limit. In both cases, channel name was supplied without # sign

with positive integers you could use .isdigit:

>>> '16'.isdigit()
True

it doesn't work with negative integers though. suppose you could try the following:

>>> s = '-17'
>>> s.startswith('-') and s[1:].isdigit()
True

it won't work with '16.0' format, which is similar to int casting in this sense.

edit:

def check_int(s):
    if s[0] in ('-', '+'):
        return s[1:].isdigit()
    return s.isdigit()

border: 0 should be enough, but if it isn't, perhaps the button's browser-default styling in interfering. Have you tried setting appearance to none (e.g. -webkit-appearance: none)

This example shows how to use the method GetInvocationList() to retrieve delegates to all the handlers that have been added. If you are looking to see if a specific handler (function) has been added then you can use array.

public class MyClass
{
  event Action MyEvent;
}

...

MyClass myClass = new MyClass();
myClass.MyEvent += SomeFunction;

...

Action[] handlers = myClass.MyEvent.GetInvocationList(); //this will be an array of 1 in this example

Console.WriteLine(handlers[0].Method.Name);//prints the name of the method

You can examine various properties on the Method property of the delegate to see if a specific function has been added.

If you are looking to see if there is just one attached, you can just test for null.

This will end the function, and you can even customize the "Error" message:

import sys

def end():
    if condition:
        # the player wants to play again:
        main()
    elif not condition:
        sys.exit("The player doesn't want to play again") #Right here 

Have a look at json_encode() in PHP. You can get $.ajax to recognize this with the dataType: "json" parameter.

1) You can set root password by invoking MySQL console. It is located in

C:\wamp\bin\mysql\mysql5.1.53\bin by default.

Get to the directory and type MySQL. then set the password as follows..

    > SET PASSWORD FOR root@localhost = PASSWORD('new-password');

2) You can configure wamp's phpmyadmin application for root user by editing

C:\wamp\apps\phpmyadmin3.3.9\config.inc.php 

Note :- if you are using xampp then , file will be located at

C:\xampp\phpMyadmin\config.inc.php

It looks like this:

        $cfg['Servers'][$i]['verbose'] = 'localhost';
        $cfg['Servers'][$i]['host'] = 'localhost';
        $cfg['Servers'][$i]['port'] = '';
        $cfg['Servers'][$i]['socket'] = '';
        $cfg['Servers'][$i]['connect_type'] = 'tcp';
        $cfg['Servers'][$i]['extension'] = 'mysqli';
        $cfg['Servers'][$i]['auth_type'] = 'config';
        $cfg['Servers'][$i]['user'] = 'root';
        $cfg['Servers'][$i]['password'] = 'YOURPASSWORD';
        $cfg['Servers'][$i]['AllowNoPassword'] = false;

The error "Access denied for user 'root@localhost' (using password:NO)" will be resolved when you set $cfg['Servers'][$i]['AllowNoPassword'] to false

If you priviously changed the password for 'root@localhost', then you have to do 2 things to solve the error "Access denided for user 'root@localhost'":

1. if ['password'] have a empty quotes like ' ' then put your password between quotes.
2. change the (using password:NO) to (using password:YES)

This will resolve the error.

Note: phpmyadmin is a separate tool which comes with wamp. It just provide a interface to MySQL. if you change my sql root's password, then you should change the phpmyadmin configurations. Usually phpmyadmin is configured to root user.

My opinionated solution:

function objFilter(obj, filter, nonstrict){
  r = {}
  if (!filter) return {}
  if (typeof filter == 'string') return {[filter]: obj[filter]}
  for (p in obj) {
    if (typeof filter == 'object' &&  nonstrict && obj[p] ==  filter[p]) r[p] = obj[p]
    else if (typeof filter == 'object' && !nonstrict && obj[p] === filter[p]) r[p] = obj[p]
    else if (typeof filter == 'function'){ if (filter(obj[p],p,obj)) r[p] = obj[p]}
    else if (filter.length && filter.includes(p)) r[p] = obj[p]
  }
  return r
}

Test cases:

obj = {a:1, b:2, c:3}

objFilter(obj, 'a') // returns: {a: 1}
objFilter(obj, ['a','b']) // returns: {a: 1, b: 2}
objFilter(obj, {a:1}) // returns: {a: 1}
objFilter(obj, {'a':'1'}, true) // returns: {a: 1}
objFilter(obj, (v,k,o) => v%2===1) // returns: {a: 1, c: 3}

Based on what you all shared I was able to put this together:

#!/usr/bin/env bash

VAR1="192.168.1.20 192.168.1.126 192.168.1.36"

for a in $VAR1; do { ssh -t -t $a -l Administrator "sudo softwareupdate -l"; } & done;
WAITPIDS="$WAITPIDS "$!;...; wait $WAITPIDS
echo "Script has finished"

Exit 1

This lists all the updates on the mac on three machines at once. Later on I used it to perform a software update for all machines when i CAT my ipaddress.txt

The If else statement needs to be wrapped in a .get or a .post to redirect. Such as

app.post('/login', function(req, res) {
});

or

app.get('/login', function(req, res) {
});

For portability to pre-Bash 3.1 (when the =~ test was introduced), use expr.

if expr "$string" : '-\?[0-9]\+$' >/dev/null
then
  echo "String is a valid integer."
else
  echo "String is not a valid integer."
fi

expr STRING : REGEX searches for REGEX anchored at the start of STRING, echoing the first group (or length of match, if none) and returning success/failure. This is old regex syntax, hence the excess \. -\? means "maybe -", [0-9]\+ means "one or more digits", and $ means "end of string".

Bash also supports extended globs, though I don't recall from which version onwards.

shopt -s extglob
case "$string" of
    @(-|)[0-9]*([0-9]))
        echo "String is a valid integer." ;;
    *)
        echo "String is not a valid integer." ;;
esac

# equivalently, [[ $string = @(-|)[0-9]*([0-9])) ]]

@(-|) means "- or nothing", [0-9] means "digit", and *([0-9]) means "zero or more digits".

If you want the placeholder text to be red you need to target it specifically in CSS.

Write:

input::placeholder{
  color: #f00;
}

function update(datetime = "2017-01-01 05:11:58") {
    var theevent = new Date(datetime);
    now = new Date();
    var sec_num = (theevent - now) / 1000;
    var days    = Math.floor(sec_num / (3600 * 24));
    var hours   = Math.floor((sec_num - (days * (3600 * 24)))/3600);
    var minutes = Math.floor((sec_num - (days * (3600 * 24)) - (hours * 3600)) / 60);
    var seconds = Math.floor(sec_num - (days * (3600 * 24)) - (hours * 3600) - (minutes * 60));

    if (hours   < 10) {hours   = "0"+hours;}
    if (minutes < 10) {minutes = "0"+minutes;}
    if (seconds < 10) {seconds = "0"+seconds;}

    return  days+':'+ hours+':'+minutes+':'+seconds;
}

split takes regex as a parameter.| has special meaning in regex.. use \\| instead of | to escape it.

You can also use:

Range( RangeName ).end(xlDown).row

to find the last row with data in it starting at your named range.

You can use the below code:

1. For Single Table Structure alone Backup

-

mysqldump -d <database name> <tablename> > <filename.sql>

2. For Single Table Structure with data

-

mysqldump <database name> <tablename> > <filename.sql>

Hope it will help.
