Programs & Examples On #Zeta components

The jquery BalusC's solution improved by me. Used also: Brad Robertson's comment here.

Just put this in a .js, use the wide class for your desired combos and don't forge to give it an Id. Call the function in the onload (or documentReady or whatever).
As simple ass that :)
It will use the width that you defined for the combo as minimun length.

function fixIeCombos() {
    if ($.browser.msie && $.browser.version < 9) {
    var style = $('<style>select.expand { width: auto; }</style>');
    $('html > head').append(style);

    var defaultWidth = "200";

    // get predefined combo's widths.
    var widths = new Array();
    $('select.wide').each(function() {
        var width = $(this).width();
        if (!width) {
        width = defaultWidth;
        }
        widths[$(this).attr('id')] = width;
    });

    $('select.wide')
    .bind('focus mouseover', function() {
        // We're going to do the expansion only if the resultant size is bigger
        // than the original size of the combo.
        // In order to find out the resultant size, we first clon the combo as
        // a hidden element, add to the dom, and then test the width.
        var originalWidth = widths[$(this).attr('id')];

        var $selectClone = $(this).clone();
        $selectClone.addClass('expand').hide();
        $(this).after( $selectClone );
        var expandedWidth = $selectClone.width()
        $selectClone.remove();
        if (expandedWidth > originalWidth) {
        $(this).addClass('expand').removeClass('clicked');
        }
    })
    .bind('click', function() {
        $(this).toggleClass('clicked'); 
    })
    .bind('mouseout', function() {
        if (!$(this).hasClass('clicked')) {
        $(this).removeClass('expand');
        }
    })
    .bind('blur', function() {
        $(this).removeClass('expand clicked');
    })
    }
}

There are no problems with the second version of the assignment operator. In fact, that is the standard way for an assignment operator.

Edit: Note that I am referring to the return type of the assignment operator, not to the implementation itself. As has been pointed out in comments, the implementation itself is another issue. See here.

One might also use, works ok in all browsers, require javascript:

onselectstart = (e) => {e.preventDefault()}

Example:

onselectstart = (e) => {_x000D_
  e.preventDefault()_x000D_
  console.log("nope!")_x000D_
  }

Select me!

One other js alternative, by testing CSS supports, and disable userSelect, or MozUserSelect for Firefox.

let FF_x000D_
if (CSS.supports("( -moz-user-select: none )")){FF = 1} else {FF = 0}_x000D_
(FF===1) ? document.body.style.MozUserSelect="none" : document.body.style.userSelect="none"

Select me!

Pure css, same logic. Warning you will have to extend those rules to every browser, this can be verbose.

@supports (user-select:none) {_x000D_
  div {_x000D_
    user-select:none_x000D_
  }_x000D_
}_x000D_
_x000D_
@supports (-moz-user-select:none) {_x000D_
  div {_x000D_
    -moz-user-select:none_x000D_
  }_x000D_
}

<div>Select me!</div>

May be your properties are getting overridden. Try attaching !important to your code along with the :active .

.btn:focus,.btn:active {
   outline: none !important;
   box-shadow: none;
}

Also add box-shadow because otherwise you will still see the shadow around button.

Although this isn't a good practise to use !important I suggest you use more specific class and then try applying the css with the use of !important...

Suspose we wish to access various views with dynamic component loading.The following code gives a working example of how to accomplish this by using a string parsed from the search string of a url.

Lets assume we want to access a page 'snozberrys' with two unique views using these url paths:

'http://localhost:3000/snozberrys?aComponent'

and

'http://localhost:3000/snozberrys?bComponent'

we define our view's controller like this:

import React, { Component } from 'react';
import ReactDOM from 'react-dom'
import {
  BrowserRouter as Router,
  Route
} from 'react-router-dom'
import AComponent from './AComponent.js';
import CoBComponent sole from './BComponent.js';

const views = {
  aComponent: <AComponent />,
  console: <BComponent />
}

const View = (props) => {
  let name = props.location.search.substr(1);
  let view = views[name];
  if(view == null) throw "View '" + name + "' is undefined";
  return view;
}

class ViewManager extends Component {
  render() {
    return (
      <Router>
        <div>
          <Route path='/' component={View}/>
        </div>
      </Router>
    );
  }
}

export default ViewManager

ReactDOM.render(<ViewManager />, document.getElementById('root'));

Taking the answer from ZyX using pure bash but with new style regex matching and indirect parameter substitution it becomes:

#!/bin/bash
regex='\$\{([a-zA-Z_][a-zA-Z_0-9]*)\}'
while read line; do
    while [[ "$line" =~ $regex ]]; do
        param="${BASH_REMATCH[1]}"
        line=${line//${BASH_REMATCH[0]}/${!param}}
    done
    echo $line
done

You can take database back-up of SQL server instance using C#, as below

Step 1: Install Nuget package "Install-Package Microsoft.SqlServer.SqlManagementObjects"

Step 2: Use the below C# Command to take backup using Custom function

public void BackupDatabase(string databaseName, string userName, string password, string serverName, string destinationPath)

 {  
//Define a Backup object variable.
Backup sqlBackup = new Backup();
//Specify the type of backup, the description, the name, and the database to be backed up.
sqlBackup.Action = BackupActionType.Database;

sqlBackup.BackupSetDescription = "BackUp of:" + databaseName + "on" + DateTime.Now.ToShortDateString();

sqlBackup.BackupSetName = "FullBackUp";

sqlBackup.Database = databaseName;
//Declare a BackupDeviceItem
BackupDeviceItem deviceItem = new BackupDeviceItem(destinationPath + "FullBackUp.bak", DeviceType.File);

//Define Server connection
ServerConnection connection = new ServerConnection(serverName, userName, password); //To Avoid TimeOut Exception
Server sqlServer = new Server(connection);
sqlServer.ConnectionContext.StatementTimeout = 60 * 60;
Database db = sqlServer.Databases[databaseName];
(Reference Database As microsoft.sqlserver.management.smo.database, not as System.entity.database)

sqlBackup.Initialize = true;

sqlBackup.Checksum = true;

sqlBackup.ContinueAfterError = true;
//Add the device to the Backup object.
sqlBackup.Devices.Add(deviceItem);

//Set the Incremental property to False to specify that this is a full database backup. 
sqlBackup.Incremental = false;
sqlBackup.ExpirationDate = DateTime.Now.AddDays(3);

//Specify that the log must be truncated after the backup is complete.        
sqlBackup.LogTruncation = BackupTruncateLogType.Truncate;
sqlBackup.FormatMedia = false;

//Run SqlBackup to perform the full database backup on the instance of SQL Server. 
sqlBackup.SqlBackup(sqlServer);

//Remove the backup device from the Backup object.           
 sqlBackup.Devices.Remove(deviceItem);

}

Microsoft.SqlServer.ConnectionInfo
Microsoft.SqlServer.Management.Sdk.Sfc
Microsoft.SqlServer.Smo
Microsoft.SqlServer.SmoExtended
Microsoft.SqlServer.SqlEnum

That's it, you are done, it will take backup of specified database at specified location passed to the function.

Source: Various ways to back up SQL server database

Note: User must have proper rights to write backup data on specified disk location.

Remove :

npm uninstall -g angular-cli

Reinstall (with yarn)

# npm install --global yarn
yarn global add @angular/cli@latest
ng set --global packageManager=yarn  # This will help ng-cli to use yarn

Reinstall (with npm)

npm install --global @angular/cli@latest

Another way is to not use global install, and add /node_modules/.bin folder in the PATH, or use npm scripts. It will be softer to upgrade.

In iOS SDK When your API call time-outs, you get status 0 for that.

input[type='text'], input[type='password']
{
   // my css
}

That is the correct way to do it. Sadly CSS is not a programming language.

You can change the CSS color property using JavaScript in the onclick event handler (in the same way you change the value property):

<input type="text" onclick="this.value=''; this.style.color='#000'" />

Note that it's not the best practice to use inline JavaScript. You'd be better off giving your input an ID, and moving your JavaScript out to a <script> block instead:

document.getElementById("yourInput").onclick = function() {
    this.value = '';
    this.style.color = '#000';
}

It is not valid for TypeScript as:

declare function isNaN(number: number): boolean;

For TypeScript you can use:

/^\d+$/.test(key)

String[] columnDetail = new String[11];
columnDetail = column.split("\t", -1); // unlimited
OR
columnDetail = column.split("\t", 11); // if you are sure about limit.

 * The {@code limit} parameter controls the number of times the
 * pattern is applied and therefore affects the length of the resulting
 * array.  If the limit <i>n</i> is greater than zero then the pattern
 * will be applied at most <i>n</i>&nbsp;-&nbsp;1 times, the array's
 * length will be no greater than <i>n</i>, and the array's last entry
 * will contain all input beyond the last matched delimiter.  If <i>n</i>
 * is non-positive then the pattern will be applied as many times as
 * possible and the array can have any length.  If <i>n</i> is zero then
 * the pattern will be applied as many times as possible, the array can
 * have any length, and trailing empty strings will be discarded.

Aside from object initializers (usable only in constructor calls), the best you can get is:

var it = Stuff.Elements.Foo;
it.Name = "Bob Dylan";
it.Age = 68;
...

As DOC says, you can pass data to the handler as next:

// say your selector and click handler looks something like this...
$("some selector").on('click',{param1: "Hello", param2: "World"}, cool_function);

// in your function, just grab the event object and go crazy...
function cool_function(event){
    alert(event.data.param1);
    alert(event.data.param2);

    // access element's id where click occur
    alert( event.target.id ); 
}

You can use

t1<- t1[-4:-6,-7:-9]  

or

t1 <- t1[-(4:6), -(7:9)]

or

t1 <- t1[-c(4, 5, 6), -c(7, 8, 9)]

You can pass vectors to select rows/columns to be deleted. First two methods are useful if you are trying to delete contiguous rows/columns. Third method is useful if You are trying to delete discrete rows/columns.

> t1 <- array(1:20, dim=c(10,10));

> t1[-c(1, 4, 6, 7, 9), -c(2, 3, 8, 9)]

     [,1] [,2] [,3] [,4] [,5] [,6]
[1,]    2   12    2   12    2   12
[2,]    3   13    3   13    3   13
[3,]    5   15    5   15    5   15
[4,]    8   18    8   18    8   18
[5,]   10   20   10   20   10   20

all you need to know is in Jackson Documentation https://www.baeldung.com/jackson-serialize-dates

Ad.9 quick solved the problem for me.

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);

i make in word by doing this:

dpkg-reconfigure locales

and choose your preferred locales

pg_createcluster 9.5 main --start

(9.5 is my version of postgresql)

/etc/init.d/postgresql start

and then it word!

sudo su - postgres
psql

Old post but I made an good solution what is tested on serval places.

https://github.com/CreativForm/Load-jQuery-if-it-is-not-already-loaded

CODE:

(function(url, position, callback){
    // default values
    url = url || 'https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js';
    position = position || 0;

    // Check is jQuery exists
    if (!window.jQuery) {
        // Initialize <head>
        var head = document.getElementsByTagName('head')[0];
        // Create <script> element
        var script = document.createElement("script");
        // Append URL
        script.src = url;
        // Append type
        script.type = 'text/javascript';
        // Append script to <head>
        head.appendChild(script);
        // Move script on proper position
        head.insertBefore(script,head.childNodes[position]);

        script.onload = function(){
            if(typeof callback == 'function') {
                callback(jQuery);
            }
        };
    } else {
        if(typeof callback == 'function') {
            callback(jQuery);
        }
    }
}('https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js', 5, function($){ 
    console.log($);
}));

At GitHub is better explanation but generaly this function you can add anywhere in your HTML code and you will initialize jquery if is not already loaded.

Such behavior of ruby is really frustrating. I mean if you move to private section self.method then it is NOT private. But if you move it to class << self then it suddenly works. It is just disgusting.

Confusing it probably is, frustrating it may well be, but disgusting it is definitely not.

It makes perfect sense once you understand Ruby's object model and the corresponding method lookup flow, especially when taking into consideration that private is NOT an access/visibility modifier, but actually a method call (with the class as its recipient) as discussed here... there's no such thing as "a private section" in Ruby.

To define private instance methods, you call private on the instance's class to set the default visibility for subsequently defined methods to private... and hence it makes perfect sense to define private class methods by calling private on the class's class, ie. its metaclass.

Other mainstream, self-proclaimed OO languages may give you a less confusing syntax, but you definitely trade that off against a confusing and less consistent (inconsistent?) object model without the power of Ruby's metaprogramming facilities.

Sanity testing

Sanity testing is the subset of regression testing and it is performed when we do not have enough time for doing testing.

Sanity testing is the surface level testing where QA engineer verifies that all the menus, functions, commands available in the product and project are working fine.

Example

For example, in a project there are 5 modules: Login Page, Home Page, User's Details Page, New User Creation and Task Creation.

Suppose we have a bug in the login page: the login page's username field accepts usernames which are shorter than 6 alphanumeric characters, and this is against the requirements, as in the requirements it is specified that the username should be at least 6 alphanumeric characters.

Now the bug is reported by the testing team to the developer team to fix it. After the developing team fixes the bug and passes the app to the testing team, the testing team also checks the other modules of the application in order to verify that the bug fix does not affect the functionality of the other modules. But keep one point always in mind: the testing team only checks the extreme functionality of the modules, it does not go deep to test the details because of the short time.

Sanity testing is performed after the build has cleared the smoke tests and has been accepted by QA team for further testing. Sanity testing checks the major functionality with finer details.

Sanity testing is performed when the development team needs to know quickly the state of the product after they have done changes in the code, or there is some controlled code changed in a feature to fix any critical issue, and stringent release time-frame does not allow complete regression testing.

Smoke testing

Smoke Testing is performed after a software build to ascertain that the critical functionalities of the program are working fine. It is executed "before" any detailed functional or regression tests are executed on the software build.

The purpose is to reject a badly broken application, so that the QA team does not waste time installing and testing the software application.

In smoke testing, the test cases chosen cover the most important functionalities or components of the system. The objective is not to perform exhaustive testing, but to verify that the critical functionalities of the system are working fine. For example, typical smoke tests would be:

• verify that the application launches successfully,
• Check that the GUI is responsive

I have had to resort to this, but this has issues with upkeep.

Function sheet_match(rng As Range) As String  ' Converts Excel TAB names to the required VSB Sheetx names.
  TABname = rng.Worksheet.Name                ' Excel sheet TAB name, not VSB Sheetx name. Thanks, Bill Gates.
' Next, match this Excel sheet TAB name to the VSB Sheetx name:
   Select Case TABname 'sheet_match
      Case Is = "Sheet1": sheet_match = "Sheet1"  ' You supply these relationships
      Case Is = "Sheet2": sheet_match = "Sheet2"

      Case Is = "Sheet7": sheet_match = "Sheet7"
      Case Is = "Sheet8": sheet_match = "Sheet8"

Use the bootstrap classes to your advantage. navbar-static-bottom leaves it at the bottom.

<div class="navbar-static-bottom" id="footer"></div>

You made a simple mistake. Don't worry.... Simply use getElementById instead getElementsById

true

var first_number = parseInt(document.getElementById("Text1").value);

False

var first_number = parseInt(document.getElementsById("Text1").value);

Thanks ...

The 487 Response indicates that the previous request was terminated by user/application action. The most common occurrence is when the CANCEL happens as explained above. But it is also not limited to CANCEL. There are other cases where such responses can be relevant. So it depends on where you are seeing this behavior and whether its a user or application action that caused it.

15.1.2 UAS Behavior==> BYE Handling in RFC 3261

The UAS MUST still respond to any pending requests received for that dialog. It is RECOMMENDED that a 487 (Request Terminated) response be generated to those pending requests.

I was getting the same error and inspite of doing everything mentioned here and elsewhere nothing worked. Turned out that I had copied the source code of global.asax.cs from a previous version of the project which had a different name. So the namespace Test should have been namespace Test.WebUI. A silly mistake of course and am a bit embarrassed to write this! But writing in the hope that a similar error from anyone else may lead him to check this trivial aspect as well.

Oddly enough, the issue for me was I was trying to open 2012 SQL Server Integration Services on SSMS 2008 R2. When I opened the same in SSMS 2012, it connected right away.

If you're looking to put line breaks into the tooltip that appears on mouseover, there's no reliable crossbrowser way to do that. You'd have to fall back to one of the many Javascript tooltip code samples

Simplest solution would be to use tool which allows you to directly specify ranges, like gnu shuf

shuf -i1-10 -n1

If you want to use $RANDOM, it would be more precise to throw out the last 8 numbers in 0...32767, and just treat it as 0...32759, since taking 0...32767 mod 10 you get the following distribution

0-8 each: 3277 
8-9 each: 3276

So, slightly slower but more precise would be

while :; do ran=$RANDOM; ((ran < 32760)) && echo $(((ran%10)+1)) && break; done 

new File(absolutePath).getName();

This is a version of Ben James's answer, above:

>>> import datetime
>>> x = datetime.date.today()
>>> print x
2013-01-11
>>> 
>>> 
>>> print "Today's date is %s ..." % x
Today's date is 2013-01-11 ...
>>> 
>>> print "Today's date is %r ..." % x
Today's date is datetime.date(2013, 1, 11) ...
>>>

When I ran this, it helped me see the usefulness of %r.

System.out.println("hello"+"\n"+"world");

I'm surprised no one mentioned the HTML entities   and   which produce horizontal white space equivalent to the characters n and m, respectively. If you want to accumulate horizontal white space quickly, those are more efficient than  .

1. no space
2.   
3.  
4.  

Along with <space> and  , these are the five entities HTML provides for horizontal white space.

Note that except for  , all entities allow breaking. Whatever text surrounds them will wrap to a new line if it would otherwise extend beyond the container boundary. With   it would wrap to a new line as a block even if the text before   could fit on the previous line.

Depending on your use case, that may be desired or undesired. For me, unless I'm dealing with things like names (John Doe), addresses or references (see eq. 5), breaking as a block is usually undesired.

Quite simple with a closure:

def map = [
           'iPhone':'iWebOS',
           'Android':'2.3.3',
           'Nokia':'Symbian',
           'Windows':'WM8'
           ]

map.each{ k, v -> println "${k}:${v}" }

If you want the original URL just use the method as described by jthalborn. If you want to rebuild the url do like David Levesque explained, here is a code snippet for it:

final javax.servlet.http.HttpServletRequest req = (javax.servlet.http.HttpServletRequest) ...;
final int serverPort = req.getServerPort();
if ((serverPort == 80) || (serverPort == 443)) {
  // No need to add the server port for standard HTTP and HTTPS ports, the scheme will help determine it.
  url = String.format("%s://%s/...", req.getScheme(), req.getServerName(), ...);
} else {
  url = String.format("%s://%s:%s...", req.getScheme(), req.getServerName(), serverPort, ...);
}

You still need to consider the case of a reverse-proxy:

• request.getScheme() is returning http instead of returning https in java

Could use constants for the ports but not sure if there is a reliable source for them, default ports:

• Are HTTP and HTTPS default port numbers defined in the JDK?

Most developers will know about port 80 and 443 anyways, so constants are not that helpful.

Also see this similar post.

Here the passage from the MSDN:

When you specify a PRIMARY KEY constraint for a table, the Database Engine enforces data uniqueness by creating a unique index for the primary key columns. This index also permits fast access to data when the primary key is used in queries. Therefore, the primary keys that are chosen must follow the rules for creating unique indexes.

Windows->Preferences->Server

Server Timeout can be specified there.

or another method via the Servers tab here:

http://henneberke.wordpress.com/2009/09/28/fixing-eclipse-tomcat-timeout/

You can use .empty(), like this:

$("#foo").empty();

From the docs:

Remove all child nodes of the set of matched elements from the DOM.

The best way is ViewOverlay , You can add any drawable as overlay to any view as its overlay since Android JellyBeanMR2(Api 18).

Add mMyDrawable to mMyView as its overlay:

mMyDrawable.setBounds(0, 0, mMyView.getMeasuredWidth(), mMyView.getMeasuredHeight())
mMyView.getOverlay().add(mMyDrawable)

The $ is just a function. It is actually an alias for the function called jQuery, so your code can be written like this with the exact same results:

jQuery('#Text').click(function () {
  jQuery('#Text').css('color', 'red');
});

SELECT CASE WHEN EXISTS (SELECT TOP 1 *
                         FROM dbo.[YourTable] 
                         WHERE [YourColumn] = [YourValue]) 
            THEN CAST (1 AS BIT) 
            ELSE CAST (0 AS BIT) END

This approach returns a boolean for you.

The integer is being converted into a string rather than vice-versa. You want:

var newValue = parseInt(currentValue) + 1

If the line before your error contains COMMENT '' either populate the comment in the script or remove the empty comment definition. I've found this in scripts generated by MySQL Workbench.

I wouldn't set the ngmodel via an attribute, you can specify it right in the template:

template: '<div class="some"><label>{{label}}</label><input data-ng-model="ngModel"></div>',

Within your onDropDownChange handler, just make a jQuery AJAX call, passing in any data you need to pass up to your URL. You can handle successful and failure calls with the success and error options. In the success option, use the data contained in the data argument to do whatever rendering you need to do. Remember these are asynchronous by default!

function onDropDownChange(e) {
    var url = '/Home/Index/' + e.value;
    $.ajax({
      url: url,
      data: {}, //parameters go here in object literal form
      type: 'GET',
      datatype: 'json',
      success: function(data) { alert('got here with data'); },
      error: function() { alert('something bad happened'); }
    });
}

jQuery's AJAX documentation is here.

I use this code and RUN SUCCESS FULL:

$filename = 'apptoko-2016-12-23.sql'; //change to ur .sql file
                            $handle = fopen($filename, "r+");
                            $contents = fread($handle, filesize($filename));

                            $sql = explode(";",$contents);// 
                            foreach($sql as $query){
                                $result=mysql_query($query);
                                if ($result){
                                 echo '<tr><td><BR></td></tr>';
                                 echo '<tr><td>' . $query . ' <b>SUCCESS</b></td></tr>';
                                 echo '<tr><td><BR></td></tr>';
                                }
                            }
                            fclose($handle);

The problem in my case was in the discrepancy between the Gradle version installed globally and the one required by React Native. To fix it, I had to update the folder android/gradle/wrapper from the current 6.5 RN version from GH.

sep='' in the context of a function call sets the named argument sep to an empty string. See the print() function; sep is the separator used between multiple values when printing. The default is a space (sep=' '), this function call makes sure that there is no space between Property tax: $ and the formatted tax floating point value.

Compare the output of the following three print() calls to see the difference

>>> print('foo', 'bar')
foo bar
>>> print('foo', 'bar', sep='')
foobar
>>> print('foo', 'bar', sep=' -> ')
foo -> bar

All that changed is the sep argument value.

\t in a string literal is an escape sequence for tab character, horizontal whitespace, ASCII codepoint 9.

\t is easier to read and type than the actual tab character. See the table of recognized escape sequences for string literals.

Using a space or a \t tab as a print separator shows the difference:

>>> print('eggs', 'ham')
eggs ham
>>> print('eggs', 'ham', sep='\t')
eggs    ham

from datetime import datetime 
from dateutil.relativedelta import relativedelta
d = datetime.now()
date = datetime.isoformat(d).split('.')[0]
d_month = datetime.today() + relativedelta(months=1)
next_month = datetime.isoformat(d_month).split('.')[0]

Maybe you can try to use the function gc(). A call of gc() causes a garbage collection to take place. It can be useful to call gc() after a large object has been removed, as this may prompt R to return memory to the operating system. gc() also return a summary of the occupy memory.

Maybe you can build a function / static class Method that does exactly that. I use Kohana which has a nice function called:

Kohana::Debug

That will do what you want. That's reduces it to only one line. A simple function will look like

function debug($input) {
    echo "<pre>";
    print_r($input);
    echo "</pre>";
}

When you are using JVM in 32-bit mode, the maximum heap size that can be allocated is 1280 MB. So, if you want to go beyond that, you need to invoke JVM in 64-mode.

You can use following:

$ java -d64 -Xms512m -Xmx4g HelloWorld

where,

• -d64: Will enable 64-bit JVM
• -Xms512m: Will set initial heap size as 512 MB
• -Xmx4g: Will set maximum heap size as 4 GB

You can tune in -Xms and -Xmx as per you requirements (YMMV)

A very good resource on JVM performance tuning, which might want to look into: http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html

The answer of this question is lies in the internal working of java compiler(constructor chaining). If we see the internal working of java compiler:

public class Bank {
  public void printBankBalance(){
    System.out.println("10k");
  }
}
class SBI extends Bank{
 public void printBankBalance(){
    System.out.println("20k");
  }
}

After compiling this look like:

public class Bank {
  public Bank(){
   super();
  }
  public void printBankBalance(){
    System.out.println("10k");
  }
}
class SBI extends Bank {
 SBI(){
   super();
 }
 public void printBankBalance(){
    System.out.println("20k");
  }
}

when we extends class and create an object of it, one constructor chain will run till Object class.

Above code will run fine. but if we have another class called Car which extends Bank and one hybrid(multiple inheritance) class called SBICar:

class Car extends Bank {
  Car() {
    super();
  }
  public void run(){
    System.out.println("99Km/h");
  }
}
class SBICar extends Bank, Car {
  SBICar() {
    super(); //NOTE: compile time ambiguity.
  }
  public void run() {
    System.out.println("99Km/h");
  }
  public void printBankBalance(){
    System.out.println("20k");
  }
}

In this case(SBICar) will fail to create constructor chain(compile time ambiguity).

For interfaces this is allowed because we cannot create an object of it.

For new concept of default and static method kindly refer default in interface.

Hope this will solve your query. Thanks.

You can use top_n

df %>% group_by(A, B) %>% top_n(n=1)

This will rank by the last column (value) and return the top n=1 rows.

Currently, you can't change the this default without causing an error (See https://github.com/hadley/dplyr/issues/426)

I think the LINQ expression may be best:

   const string MyKey = "myKey"

   if (ConfigurationManager.AppSettings.AllKeys.Any(key => key == MyKey))
          {
              // Key exists
          }

Additional information

Sometimes it is necessary to bind a model into a view models and give a type conversion error. In this situation you should use ToList() method.

var list = (from t in ctn.Items
       where t.DeliverySelection == true && t.Delivery.SentForDelivery == null
       orderby t.Delivery.SubmissionDate
       select t).Take(5).ToList();

String array[]={"one","two"};
String s="";

for(int i=0;i<array.length;i++)
{
  s=s+array[i];
}

System.out.print(s);

As option, if you need just default text in dropdown without default value, try add <option disabled value="null">default text here</option> like this:

<select id="country" formControlName="country">
 <option disabled value="null">default text here</option>
 <option *ngFor="let c of countries" [value]="c" >{{ c }}</option>
</select>

In Chrome and Firefox works fine.

If you'd decide for a solution acting "in place" you could take a look at this one:

>>> d = [ { 'a':'1' , 'b':'2' , 'c':'3' }, { 'd':'4' , 'e':'5' , 'f':'6' } ]
>>> [dt.update({k: int(v)}) for dt in d for k, v in dt.iteritems()]
[None, None, None, None, None, None]
>>> d
[{'a': 1, 'c': 3, 'b': 2}, {'e': 5, 'd': 4, 'f': 6}]

Btw, key order is not preserved because that's the way standard dictionaries work, ie without the concept of order.

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }
}

public Image ByteArrayToImage(byte[] byteArrayIn)
{
     using(var ms = new MemoryStream(byteArrayIn))
     {
         var returnImage = Image.FromStream(ms);

         return returnImage;
     }
}

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

I had to insert date at the beginning of the lines of a log file and it's done like below:

DATE=$(date +"%Y-%m-%d")
awk '{ print "'"$DATE"'", $0; }' /path_to_log_file/log_file.log

It can be redirect to another file to save

Skip all of this. Download Microsoft FUZZY LOOKUP add in. Create tables using your columns. Create a new worksheet. INPUT tables into the tool. Click all corresponding columns check boxes. Use slider for exact matches. HIT go and wait for the magic.

No, you can't use a non-standard size or dimension, as it'd wreak havoc on peoples' browsers wherever the icons are displayed. You could make it 12x16 (with four pixels of white/transparent padding on the 12 pixel side) to preserve your aspect ratio, but you can't go bigger (well, you can, but the browser'll shrink it).

Since you're already using Google's Json-Simple library, you can parse the json from an InputStream like this:

InputStream inputStream = ... //Read from a file, or a HttpRequest, or whatever.
JSONParser jsonParser = new JSONParser();
JSONObject jsonObject = (JSONObject)jsonParser.parse(
      new InputStreamReader(inputStream, "UTF-8"));

This is best answered here Question 211383

These days, any self-respecting person should be using the stated "micro-clearfix" approach of clearing floats.

You can use dict to convert string to boolean. Change this line flag = bool(reader[0]) to:

flag = {'True': True, 'False': False}.get(reader[0], False) # default is False

Sorry I dont know Java, but I was faced with the same problem tonight, so I wrote this (it's in c#)

public string IncrementString(string inboundString)    {
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(inboundString.ToArray);
bool incrementNext = false;

for (l = -(bytes.Count - 1); l <= 0; l++) {
    incrementNext = false;

    int bIndex = Math.Abs(l);
    int asciiVal = Conversion.Val(bytes(bIndex).ToString);

    asciiVal += 1;

    if (asciiVal > 57 & asciiVal < 65)
        asciiVal = 65;
    if (asciiVal > 90) {
        asciiVal = 48;
        incrementNext = true;
    }

    bytes(bIndex) = System.Text.Encoding.ASCII.GetBytes({ Strings.Chr(asciiVal) })(0);

    if (incrementNext == false)
        break; // TODO: might not be correct. Was : Exit For
}

inboundString = System.Text.Encoding.ASCII.GetString(bytes);

return inboundString;
}

It's example from great MSDN article about using ExpandoObject for creating dynamic ad-hoc types for incoming structured data (i.e XML, Json).

We can also assign delegate to ExpandoObject's dynamic property:

dynamic person = new ExpandoObject();
person.FirstName = "Dino";
person.LastName = "Esposito";

person.GetFullName = (Func<String>)(() => { 
  return String.Format("{0}, {1}", 
    person.LastName, person.FirstName); 
});

var name = person.GetFullName();
Console.WriteLine(name);

Thus it allows us to inject some logic into dynamic object at runtime. Therefore, together with lambda expressions, closures, dynamic keyword and DynamicObject class, we can introduce some elements of functional programming into our C# code, which we knows from dynamic languages as like JavaScript or PHP.

The accepted answer only shows files in the current directory's tree. To show all of the tracked files that have been committed (on the current branch), use

git ls-tree --full-tree --name-only -r HEAD

• --full-tree makes the command run as if you were in the repo's root directory.
• -r recurses into subdirectories. Combined with --full-tree, this gives you all committed, tracked files.
• --name-only removes SHA / permission info for when you just want the file paths.
• HEAD specifies which branch you want the list of tracked, committed files for. You could change this to master or any other branch name, but HEAD is the commit you have checked out right now.

This is the method from the accepted answer to the ~duplicate question https://stackoverflow.com/a/8533413/4880003.

Take a look on life cycle of Activity

Where

***onCreate()***

Called when the activity is first created. This is where you should do all of your normal static set up: create views, bind data to lists, etc. This method also provides you with a Bundle containing the activity's previously frozen state, if there was one. Always followed by onStart().

***onStart()***

Called when the activity is becoming visible to the user. Followed by onResume() if the activity comes to the foreground, or onStop() if it becomes hidden.

And you can write your simple class to take a look when these methods call

public class TestActivity extends Activity {
    /** Called when the activity is first created. */

    private final static String TAG = "TestActivity";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Log.i(TAG, "On Create .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onDestroy()
    */
    @Override
    protected void onDestroy() { 
        super.onDestroy();
        Log.i(TAG, "On Destroy .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onPause()
    */
    @Override
    protected void onPause() { 
        super.onPause();
        Log.i(TAG, "On Pause .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onRestart()
    */
    @Override
    protected void onRestart() {
        super.onRestart();
        Log.i(TAG, "On Restart .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onResume()
    */
    @Override
    protected void onResume() {
        super.onResume();
        Log.i(TAG, "On Resume .....");
    }

    /* (non-Javadoc)
    * @see android.app.Activity#onStart()
    */
    @Override
    protected void onStart() {
        super.onStart();
        Log.i(TAG, "On Start .....");
    }
    /* (non-Javadoc)
    * @see android.app.Activity#onStop()
    */
    @Override
    protected void onStop() {
        super.onStop();
        Log.i(TAG, "On Stop .....");
    }
}

Hope this will clear your confusion.

And take a look here for details.

Lifecycle Methods in Details is a very good example and demo application, which is a very good article to understand the life cycle.

Shouldn't creating a new Runnable class make a new second thread?

No. new Runnable does not create second Thread.

What is the purpose of the Runnable class here apart from being able to pass a Runnable class to postAtTime?

Runnable is posted to Handler. This task runs in the thread, which is associated with Handler.

If Handler is associated with UI Thread, Runnable runs in UI Thread.

If Handler is associated with other HandlerThread, Runnable runs in HandlerThread

To explicitly associate Handler to your MainThread ( UI Thread), write below code.

Handler  mHandler = new Handler(Looper.getMainLooper();

If you write is as below, it uses HandlerThread Looper.

HandlerThread handlerThread = new HandlerThread("HandlerThread");
handlerThread.start();
Handler requestHandler = new Handler(handlerThread.getLooper());

Your code is fine.You can also use the same thing in this way.

public static String getResponseFromJsonURL(String url) {
    String jsonResponse = null;
    if (CommonUtility.isNotEmpty(url)) {
        try {
            /************** For getting response from HTTP URL start ***************/
            URL object = new URL(url);

            HttpURLConnection connection = (HttpURLConnection) object
                    .openConnection();
            // int timeOut = connection.getReadTimeout();
            connection.setReadTimeout(60 * 1000);
            connection.setConnectTimeout(60 * 1000);
            String authorization="xyz:xyz$123";
            String encodedAuth="Basic "+Base64.encode(authorization.getBytes());
            connection.setRequestProperty("Authorization", encodedAuth);
            int responseCode = connection.getResponseCode();
            //String responseMsg = connection.getResponseMessage();

            if (responseCode == 200) {
                InputStream inputStr = connection.getInputStream();
                String encoding = connection.getContentEncoding() == null ? "UTF-8"
                        : connection.getContentEncoding();
                jsonResponse = IOUtils.toString(inputStr, encoding);
                /************** For getting response from HTTP URL end ***************/

            }
        } catch (Exception e) {
            e.printStackTrace();

        }
    }
    return jsonResponse;
}

Its Return response code 200 if authorizationis success

override func viewDidLoad() {
    super.viewDidLoad()
    self.view.backgroundColor = UIColor(patternImage: UIImage(named: "background.png"))
}

If you're using T-SQL, the only thing wrong with your code is that you used braces {} instead of parentheses ().

PS: Both IDENTITY and PRIMARY KEY imply NOT NULL, so you can omit that if you wish.

I assume you're using typescript.

To be extra cautious you can define your type as an array of objects that need to match certain interface:

type MyArrayType = Array<{id: number, text: string}>;

const arr: MyArrayType = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

Or short syntax without defining a custom type:

const arr: Array<{id: number, text: string}> = [...];

public <E> List<E> collectionToList(Collection<E> collection)
{
    return (collection instanceof List) ? (List<E>) collection : new ArrayList<E>(collection);
}

Use the above method for converting the collection to list

Quoting from http://dev.mysql.com/doc/refman/5.1/en/create-table.html

{INDEX|KEY}

So KEY is an INDEX ;)

if my_list is the list that you want to store your objects in it and my_object is your object wanted to be stored, use this structure:

my_list.append(my_object)

VB.NET

Linha.Split(" ").ToList().Where(Function(x) x <> " ").ToArray

C#

Linha.Split(" ").ToList().Where(x => x != " ").ToArray();

Enjoy the power of LINQ =D

All of the answers already given are really good and valid (especially Yunus idea of using the mask property).

However I needed something a little more complex because my layer could often change sizes which mean I needed to call that masking logic every time and this was a little bit annoying.

I used swift extensions and computed properties to build a real cornerRadii property which takes care of auto updating the mask when layer is layed out.

This was achieved using Peter Steinberg great Aspects library for swizzling.

Full code is here:

extension CALayer {
  // This will hold the keys for the runtime property associations
  private struct AssociationKey {
    static var CornerRect:Int8 = 1    // for the UIRectCorner argument
    static var CornerRadius:Int8 = 2  // for the radius argument
  }

  // new computed property on CALayer
  // You send the corners you want to round (ex. [.TopLeft, .BottomLeft])
  // and the radius at which you want the corners to be round
  var cornerRadii:(corners: UIRectCorner, radius:CGFloat) {
    get {
      let number = objc_getAssociatedObject(self, &AssociationKey.CornerRect)  as? NSNumber ?? 0
      let radius = objc_getAssociatedObject(self, &AssociationKey.CornerRadius)  as? NSNumber ?? 0
      return (corners: UIRectCorner(rawValue: number.unsignedLongValue), radius: CGFloat(radius.floatValue))
    }
    set (v) {
      let radius = v.radius
      let closure:((Void)->Void) = {
        let path = UIBezierPath(roundedRect: self.bounds, byRoundingCorners: v.corners, cornerRadii: CGSize(width: radius, height: radius))
        let mask = CAShapeLayer()
        mask.path = path.CGPath
        self.mask = mask
      }
      let block: @convention(block) Void -> Void = closure
      let objectBlock = unsafeBitCast(block, AnyObject.self)
      objc_setAssociatedObject(self, &AssociationKey.CornerRect, NSNumber(unsignedLong: v.corners.rawValue), .OBJC_ASSOCIATION_RETAIN)
      objc_setAssociatedObject(self, &AssociationKey.CornerRadius, NSNumber(float: Float(v.radius)), .OBJC_ASSOCIATION_RETAIN)
      do { try aspect_hookSelector("layoutSublayers", withOptions: .PositionAfter, usingBlock: objectBlock) }
      catch _ { }
    }
  }
}

I wrote a simple blog post explaining this.

WSDL: Stands for Web Service Description Language

In SOAP(simple object access protocol), when you use web service and add a web service to your project, your client application(s) doesn't know about web service Functions. Nowadays it's somehow old-fashion and for each kind of different client you have to implement different WSDL files. For example you cannot use same file for .Net and php client. The WSDL file has some descriptions about web service functions. The type of this file is XML. SOAP is an alternative for REST.

REST: Stands for Representational State Transfer

It is another kind of API service, it is really easy to use for clients. They do not need to have special file extension like WSDL files. The CRUD operation can be implemented by different HTTP Verbs(GET for Reading, POST for Creation, PUT or PATCH for Updating and DELETE for Deleting the desired document) , They are based on HTTP protocol and most of times the response is in JSON or XML format. On the other hand the client application have to exactly call the related HTTP Verb via exact parameters names and types. Due to not having special file for definition, like WSDL, it is a manually job using the endpoint. But it is not a big deal because now we have a lot of plugins for different IDEs to generating the client-side implementation.

SOA: Stands for Service Oriented Architecture

Includes all of the programming with web services concepts and architecture. Imagine that you want to implement a large-scale application. One practice can be having some different services, called micro-services and the whole application mechanism would be calling needed web service at the right time. Both REST and SOAP web services are kind of SOA.

JSON: Stands for javascript Object Notation

when you serialize an object for javascript the type of object format is JSON. imagine that you have the human class :

class Human{
 string Name;
 string Family;
 int Age;
}

and you have some instances from this class :

Human h1 = new Human(){
  Name='Saman',
  Family='Gholami',
  Age=26
}

when you serialize the h1 object to JSON the result is :

  [h1:{Name:'saman',Family:'Gholami',Age:'26'}, ...]

javascript can evaluate this format by eval() function and make an associative array from this JSON string. This one is different concept in comparison to other concepts I described formerly.

Other alternatives to an installer and gacutil are GUI tools like Gac Manager or GACAdmin. Or if you like PowerShell you could use PowerShell GAC from which I am the author.

However, one approach to dividing the dataset into train, test, cv with 0.6, 0.2, 0.2 would be to use the train_test_split method twice.

from sklearn.model_selection import train_test_split

x, x_test, y, y_test = train_test_split(xtrain,labels,test_size=0.2,train_size=0.8)
x_train, x_cv, y_train, y_cv = train_test_split(x,y,test_size = 0.25,train_size =0.75)

then you need to look in android.jar >> android >> R.class >> R >> color.

Here is the list that come with Android 4.4W I'm using:

background_dark
background_light
black
darker_gray
holo_blue_bright
holo_blue_dark
holo_blue_light
holo_green_dark
holo_green_light
holo_orange_dark
holo_orange_light
holo_purple
holo_red_dark
holo_red_light
primary_text_dark
primary_text_dark_nodisable
primary_text_light
primary_text_lignt_nodisable
secondary_text_dark
secondary_text_dark_nodisable
secondaryy_text_light
secondary_text_lignt_nodisable
tab_indicator_text
tertiary_text_dark
tertiary_text_light
transparent
white
widget_edittext_dark

To position the datepicker next to the input field you could use following code.

$('#datepicker').datepicker({
    beforeShow: function(input, inst)
    {
        inst.dpDiv.css({marginLeft: input.offsetWidth + 'px'});
    }
});

The primary committer to node-mongodb-native says:

You open do MongoClient.connect once when your app boots up and reuse the db object. It's not a singleton connection pool each .connect creates a new connection pool.

So, to answer your question directly, reuse the db object that results from MongoClient.connect(). This gives you pooling, and will provide a noticeable speed increase as compared with opening/closing connections on each db action.

just use the core https module with the https.request function. Example for a POST request (GET would be similar):

var https = require('https');

var options = {
  host: 'www.google.com',
  port: 443,
  path: '/upload',
  method: 'POST'
};

var req = https.request(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));
  res.setEncoding('utf8');
  res.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
  });
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

// write data to request body
req.write('data\n');
req.write('data\n');
req.end();

mutil init function in one package execute order:

1. const and variable defined file init() function execute

2. init function execute order by the filename asc

Delete the java.exe process in Task Manager and re-execute.It worked for me.

In the latest GitLab Community Edition version 9.2.2.:

1. You have to click on 'Settings' tab located at right most on tabs panel after opening the project.
2. Under 'Settings' you will get section 'Default Branch' dropdown which will give you all branches for the repository. Select the desired branch.
3. Scroll down to hit green colored 'Save changes' button located just after 'Project Avatar'.

Sorry for late post but still for info,I also facing same problem so I Used updated version of chromedriver ie.2.28 for updated chrome browser ie. 55 to 57 which resolved my problem.

Embedded option:

Wrap python code in a bash function.

#!/bin/bash

function current_datetime {
python - <<END
import datetime
print datetime.datetime.now()
END
}

# Call it
current_datetime

# Call it and capture the output
DT=$(current_datetime)
echo Current date and time: $DT

Use environment variables, to pass data into to your embedded python script.

#!/bin/bash

function line {
PYTHON_ARG="$1" python - <<END
import os
line_len = int(os.environ['PYTHON_ARG'])
print '-' * line_len
END
}

# Do it one way
line 80

# Do it another way
echo $(line 80)

Go dependency management summary:

• vgo if your go version is: x >= go 1.11
• dep or vendor if your go version is: go 1.6 >= x < go 1.11
• Manually if your go version is: x < go 1.6

Edit 3: Go 1.11 has a feature vgo which will replace dep.

To use vgo, see Modules documentation. TLDR below:

export GO111MODULE=on
go mod init
go mod vendor # if you have vendor/ folder, will automatically integrate
go build

This method creates a file called go.mod in your projects directory. You can then build your project with go build. If GO111MODULE=auto is set, then your project cannot be in $GOPATH.

Edit 2: The vendoring method is still valid and works without issue. vendor is largely a manual process, because of this dep and vgo were created.

Edit 1: While my old way works it's not longer the "correct" way to do it. You should be using vendor capabilities, vgo, or dep (for now) that are enabled by default in Go 1.6; see. You basically add your "external" or "dependent" packages within a vendor directory; upon compilation the compiler will use these packages first.

Found. I was able import local package with GOPATH by creating a subfolder of package1 and then importing with import "./package1" in binary1.go and binary2.go scripts like this :

binary1.go

...
import (
        "./package1"
      )
...

So my current directory structure looks like this:

myproject/
+-- binary1.go
+-- binary2.go
+-- package1/
¦   +-- package1.go
+-- package2.go

I should also note that relative paths (at least in go 1.5) also work; for example:

import "../packageX"

Your problem is this

<button type="button" value=" Send" class="btn btn-success" type="submit" id="submit" />

You've set the type twice. Your browser is only accepting the first, which is "button".

<button type="submit" value=" Send" class="btn btn-success" id="submit" />

I had a similar issue with 2 fixed elements - even though the z-index heirachy was correct, the bootstrap tooltip was hidden behind the one element wth a lower z-index.

Adding data-container="body" resolved the issue and now works as expected.

No, [^\x20-\x7E] is not ASCII.

This is real ASCII:

 [^\x00-\x7F]

Otherwise, it will trim out newlines and other special characters that are part of the ASCII table!

Yes, add it to the php.ini, restart apache and it should work.

Microsoft provides a walkthrough for creating a Windows Explorer style interface in C#.

There are also several examples on Code Project and other sites. Immediate examples are Explorer Tree, My Explorer, File Browser and Advanced File Explorer but there are others. Explorer Tree seems to look the best from the brief glance I took.

I used the search term windows explorer tree view C# in Google to find these links.

If the code of the previous posts doesn't work, give this a try:

$("a.ui-dialog-titlebar-close")[0].click();

Quite simple:

<input ng-model="somefield">
<span ng-show="!somefield.length">Please enter something!</span>
<span ng-show="somefield.length">Good boy!</span>

You could also use ng-hide="somefield.length" instead of ng-show="!somefield.length" if that reads more naturally for you.

A better alternative might be to really take advantage of the form abilities of Angular:

<form name="myform">
  <input name="myfield" ng-model="somefield" ng-minlength="5" required>
  <span ng-show="myform.myfield.$error.required">Please enter something!</span>
  <span ng-show="!myform.myfield.$error.required">Good boy!</span>
</form>

You just need to specify that you want to delete the entries from the posts table:

DELETE posts

You can use the Codecs module in the Python Standard Library, i.e.

import codecs

codecs.decode(hexstring, 'hex_codec')

You can even give multiple columns with null values and get multiple quantile values (I use 95 percentile for outlier treatment)

my_df[['field_A','field_B']].dropna().quantile([0.0, .5, .90, .95])

I use PHP as my serverside language, so the example i will write in it - but i'm sure there is a method in your server side as well.

Just have your serverside language add it from a variable. w/ php something like that would go as follows.

Do note, that this will only work if the script is loaded with the page load. If you want to load it dynamically, this solution will not help you.

</head>

I am new to Python, but after my brief research I found out that this is typical of sockets being binded. It just so happens that the socket is still being used and you may have to wait to use it. Or, you can just add:

tcpSocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

This should make the port available within a shorter time. In my case, it made the port available almost immediately.

I am surprised why there is not a CrytpoGraphic solution in place. GUID is unique but not cryptographically safe. See this Dotnet Fiddle.

var bytes = new byte[40]; // byte size
using (var crypto = new RNGCryptoServiceProvider())
  crypto.GetBytes(bytes);

var base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

In case you want to Prepend with a Guid:

var result = Guid.NewGuid().ToString("N") + base64;
Console.WriteLine(result);

A cleaner alphanumeric string:

result = Regex.Replace(result,"[^A-Za-z0-9]","");
Console.WriteLine(result);

useLayoutEffect could accomplish this with an empty set of observers ([]) if the functionality is actually similar to componentWillMount -- it will run before the first content gets to the DOM -- though there are actually two updates but they are synchronous before drawing to the screen.

for example:

function MyComponent({ ...andItsProps }) {
     useLayoutEffect(()=> {
          console.log('I am about to render!');
     },[]);

     return (<div>some content</div>);
}

The benefit over useState with an initializer/setter or useEffect is though it may compute a render pass, there are no actual re-renders to the DOM that a user will notice, and it is run before the first noticable render, which is not the case for useEffect. The downside is of course a slight delay in your first render since a check/update has to happen before painting to screen. It really does depend on your use-case, though.

I think personally, useMemo is fine in some niche cases where you need to do something heavy -- as long as you keep in mind it is the exception vs the norm.

I had the same problem, but finally discovered that it was an issue with the way I was invoking the script from an ASP web user control. I was using ClientScript.RegisterStartupScript(), but forgot to give the script a unique key (the second argument). With both scripts being assigned the same key, only the first box was actually being converted into a datepicker. So I decided to append the textbox's ID to the key to make it unique:

Page.ClientScript.RegisterStartupScript(this.GetType(), "DPSetup" + DPTextbox.ClientID, dpScript);

NOTE: This answer is from 2011. It was a really good answer back then, but as of 2015, native HTML properties are supported by most browsers, so there's (usually) no need to implement such custom logic in JS. See Edi's answer and the docs.

Before the file is uploaded, you can check the file's extension using Javascript, and prevent the form being submitted if it doesn't match. The name of the file to be uploaded is stored in the "value" field of the form element.

Here's a simple example that only allows files that end in ".gif" to be uploaded:

<script type="text/javascript">
    function checkFile() {
        var fileElement = document.getElementById("uploadFile");
        var fileExtension = "";
        if (fileElement.value.lastIndexOf(".") > 0) {
            fileExtension = fileElement.value.substring(fileElement.value.lastIndexOf(".") + 1, fileElement.value.length);
        }
        if (fileExtension.toLowerCase() == "gif") {
            return true;
        }
        else {
            alert("You must select a GIF file for upload");
            return false;
        }
    }
</script>

<form action="upload.aspx" enctype="multipart/form-data" onsubmit="return checkFile();">
    <input name="uploadFile" id="uploadFile" type="file" />

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

However, this method is not foolproof. Sean Haddy is correct that you always want to check on the server side, because users can defeat your Javascript checking by turning off javascript, or editing your code after it arrives in their browser. Definitely check server-side in addition to the client-side check. Also I recommend checking for size server-side too, so that users don't crash your server with a 2 GB file (there's no way that I know of to check file size on the client side without using Flash or a Java applet or something).

However, checking client side before hand using the method I've given here is still useful, because it can prevent mistakes and is a minor deterrent to non-serious mischief.

You should do

alert(data[0].name); //Take the property name of the first array

and not

 alert(data.myName)

jQuery should be able to sniff the dataType for you even if you don't set it so no need for JSON.parse.

Yes, it does deserialize to List<>. No need to keep it in an array and wrap/encapsulate it in a list.

public class UserHolder
{
    private List<User> users = null;

    public UserHolder()

    }

    [XmlElement("user")]
    public List<User> Users
    {
        get { return users; }
        set { users = value; }
    }
}

Deserializing code,

XmlSerializer xs = new XmlSerializer(typeof(UserHolder));
UserHolder uh = (UserHolder)xs.Deserialize(new StringReader(str));

URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
            new InputStreamReader(

Instantiate a new ArrayList:

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

Iterate over your data structure (with a for loop, for instance, more details on your code would help.) and for each element (yourElement):

myList.add(yourElement);

Regarding the issue with 'size', size is not a function on a dataframe, it is rather a property. So instead of using size(), plain size should work

Apart from that, a method like this should work

 def doCalculation(df):
    groupCount = df.size
    groupSum = df['my_labels'].notnull().sum()

    return groupCount / groupSum

dataFrame.groupby('my_labels').apply(doCalculation)

1. Add the icon to the project resources and rename to icon.

2. Open the designer of the form you want to add the icon to.

3. Append the InitializeComponent function.

4. Add this line in the top:

   this.Icon = PROJECTNAME.Properties.Resources.icon;
   

   repeat step 4 for any forms in your project you want to update

You can use these plugins;

Sublime SFTP

sublime FTPSync

if you want to call click event:

SomeButton.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));

And if you want the button looks like it is pressed:

typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(SomeButton, new object[] { true });

and unpressed after that:

typeof(Button).GetMethod("set_IsPressed", BindingFlags.Instance | BindingFlags.NonPublic).Invoke(SomeButton, new object[] { false });

or use the ToggleButton

Another solution not mentioned yet is to use: rewind(stdin);

After build. Refresh project and if still persist just right click Problems tab in eclipse and choose delete all.

It often happens if you do maven install and eclipse properties files do not get updated properly. Even though your project does not have any errors. Hopefully!

When using SQLFiddle, make sure that the separator is set to GO. Also the schema build script is executed in a different connection from the run script, so a temp table created in the one is not visible in the other. This fiddle shows that your code is valid and working in SQL 2012:

Push annotated tags, keep lightweight local

man git-tag says:

Annotated tags are meant for release while lightweight tags are meant for private or temporary object labels.

And certain behaviors do differentiate between them in ways that this recommendation is useful e.g.:

• annotated tags can contain a message, creator, and date different than the commit they point to. So you could use them to describe a release without making a release commit.

  Lightweight tags don't have that extra information, and don't need it, since you are only going to use it yourself to develop.

• git push --follow-tags will only push annotated tags
• git describe without command line options only sees annotated tags

Internals differences

• both lightweight and annotated tags are a file under .git/refs/tags that contains a SHA-1

• for lightweight tags, the SHA-1 points directly to a commit:

  git tag light
  cat .git/refs/tags/light
  

  prints the same as the HEAD's SHA-1.

  So no wonder they cannot contain any other metadata.

• annotated tags point to a tag object in the object database.

  git tag -as -m msg annot
  cat .git/refs/tags/annot
  

  contains the SHA of the annotated tag object:

  c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  and then we can get its content with:

  git cat-file -p c1d7720e99f9dd1d1c8aee625fd6ce09b3a81fef
  

  sample output:

  object 4284c41353e51a07e4ed4192ad2e9eaada9c059f
  type commit
  tag annot
  tagger Ciro Santilli <[email protected]> 1411478848 +0200
  
  msg
  -----BEGIN PGP SIGNATURE-----
  Version: GnuPG v1.4.11 (GNU/Linux)
  
  <YOUR PGP SIGNATURE>
  -----END PGP SIGNAT
  

  And this is how it contains extra metadata. As we can see from the output, the metadata fields are:

  • the object it points to
  • the type of object it points to. Yes, tag objects can point to any other type of object like blobs, not just commits.
  • the name of the tag
  • tagger identity and timestamp
  • message. Note how the PGP signature is just appended to the message

  A more detailed analysis of the format is present at: What is the format of a git tag object and how to calculate its SHA?

Bonuses

• Determine if a tag is annotated:

  git cat-file -t tag
  

  Outputs

  • commit for lightweight, since there is no tag object, it points directly to the commit
  • tag for annotated, since there is a tag object in that case

• List only lightweight tags: How can I list all lightweight tags?

Since you're dealing with values that are just supposed to be boolean anyway, just use == and convert the logical response to as.integer:

df <- data.frame(col = c("true", "true", "false"))
df
#     col
# 1  true
# 2  true
# 3 false
df$col <- as.integer(df$col == "true")
df
#   col
# 1   1
# 2   1
# 3   0

I could fix it.

Root Cause: This is a common issue when using the Sun JAXB implementation with signed jars. Essentially the JAXB implementation is trying to avoid reflection by generating a class to directly access the properties without using reflection. Unfortunately, it generates this new class in the same package as the class being accessed which is where this error comes from.

Resolution: Add the following system property to disable the JAXB optimizations that are not compatible with signed jars: -Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true

Ref: https://access.redhat.com/site/solutions/42149

To Hugo:

You probably mean list rather than array, but that points to the whole problem with type checking - you don't want to know if the object in question is a list, you want to know if it's some kind of sequence or if it's a single object. So try to use it like a sequence.

Say you want to add the object to an existing sequence, or if it's a sequence of objects, add them all

try:
   my_sequence.extend(o)
except TypeError:
  my_sequence.append(o)

One trick with this is if you are working with strings and/or sequences of strings - that's tricky, as a string is often thought of as a single object, but it's also a sequence of characters. Worse than that, as it's really a sequence of single-length strings.

I usually choose to design my API so that it only accepts either a single value or a sequence - it makes things easier. It's not hard to put a [ ] around your single value when you pass it in if need be.

(Though this can cause errors with strings, as they do look like (are) sequences.)

Here is one that we have saved off to findcol.sql so we can run it easily from within SQLPlus

                decode(data_type,'LONG',null,'LONG RAW',null,
                       'BLOB',null,'CLOB',null,'NUMBER',
                       decode(data_precision,null,to_char(data_length),
                              data_precision||','||data_scale
                             ), data_length

Since Java passes copies of arguments I feel the relevance of final is rather limited. I guess the habit comes from the C++ era where you could prohibit reference content from being changed by doing a const char const *. I feel this kind of stuff makes you believe the developer is inherently stupid as f*** and needs to be protected against truly every character he types. In all humbleness may I say, I write very few bugs even though I omit final (unless I don't want someone to override my methods and classes). Maybe I'm just an old-school dev.

Problem mainly occurs when you try to relocate the Global.asax file to another solution directory. Relocate the Global.asax file again into the default location. It will work as expected.

I think it could be used for "retroactively forking"

If you have a Git repo, and have now decided that it should have forked another repo. Retroactively you would like it to become a fork, without disrupting the team that uses the repo by needing them to target a new repo.

But I could be wrong.

You can use the finish command.

finish: Continue running until just after function in the selected stack frame returns. Print the returned value (if any). This command can be abbreviated as fin.

(See 5.2 Continuing and Stepping.)

use ADD instead of COPY. Suppose you want to copy everything in directory src from host to directory dst from container:

ADD src dst

Note: directory dst will be automatically created in container.

• if c and d are respectively the first character of s and t in which s and t differ, then c precedes d in character order.

Note: For the characters that are alphabetical letters, the character order coincides with the alphabetical order. Digits precede letters, and uppercase letters precede lowercase ones.

Example:

• house precedes household
• Household precedes house
• composer precedes computer
• H2O precedes HOTEL

Another way to detect the bitness of Office is to find out the typelib.

For example, to detect Outlook's bitness, write a .JS file as following:

function detectVersion()
    var outlooktlib = "TypeLib\\{00062FFF-0000-0000-C000-000000000046}";
    var HKCR = 0x80000000;

    var loc = new ActiveXObject("WbemScripting.SWbemLocator");
    var svc = loc.ConnectServer(null,"root\\default");
    var reg = svc.Get("StdRegProv");

    var method = reg.Methods_.Item("EnumKey");
    var inparam = method.InParameters.SpawnInstance_();
    inparam.hDefKey = HKCR;
    inparam.sSubKeyName = outlooktlib;
    var outparam = reg.ExecMethod_(method.Name,inparam);
    tlibver = outparam.sNames.toArray()[0];

    method = reg.Methods_.Item("GetStringValue");
    inparam = method.InParameters.SpawnInstance_();
    inparam.hDefKey = HKCR;
    inparam.sSubKeyName = outlooktlib + "\\" + tlibver + "\\0\\win32";
    inparam.sValueName = "";
    outparam = reg.ExecMethod_(method.Name,inparam);
    if(outparam.sValue) return "32 bit";

    method = reg.Methods_.Item("GetStringValue");
    inparam = method.InParameters.SpawnInstance_();
    inparam.hDefKey = HKCR;
    inparam.sSubKeyName = outlooktlib + "\\" + tlibver + "\\0\\win64";
    inparam.sValueName = "";
    outparam = reg.ExecMethod_(method.Name,inparam);
    if(outparam.sValue) return "64 bit";

    return "Not installed or unrecognizable";
}

You could find out other Office component's typelib id, and replace the first line of the function for it. Here is a brief list of interesting IDs:

{4AFFC9A0-5F99-101B-AF4E-00AA003F0F07} - Access
{00020905-0000-0000-C000-000000000046} - Word
{00020813-0000-0000-C000-000000000046} - Excel
{91493440-5A91-11CF-8700-00AA0060263B} - Powerpoint
{0002123C-0000-0000-C000-000000000046} - Publisher
{0EA692EE-BB50-4E3C-AEF0-356D91732725} - OneNote 2010+
{F2A7EE29-8BF6-4A6D-83F1-098E366C709C} - OneNote 2007

All above lib id were found through the Windows SDK tool OLE-COM Object Viewer, you could find out more lib id's by using it.

The benefit of this approach is that it works for all versions of office, and provides control on every single component in you interest. Furthermore, those keys are in the HKEY_CLASSES_ROOT and deeply integrated into the system, so it is highly unlikely they were not accessible even in a sandbox environment.

You could try this...

var myTable= document.getElementById("myTable");
if(myTable== null)
    return;
var oTBody = myTable.getElementsByTagName("TBODY")[0];
if(oTBody== null)
    return;
try
{
    oTBody.innerHTML = "";
}
catch(e)
{
    for(var i=0, j=myTable.rows.length; i<j; i++)
        myTable.deleteRow(0);
}

you should see this:jquery.validate.js,add it to your project

using it like this:

<input id='email' name='email' class='required email'/>

HTML forms support GET and POST. (HTML5 at one point added PUT/DELETE, but those were dropped.)

XMLHttpRequest supports every method, including CHICKEN, though some method names are matched against case-insensitively (methods are case-sensitive per HTTP) and some method names are not supported at all for security reasons (e.g. CONNECT).

Browsers are slowly converging on the rules specified by XMLHttpRequest, but as the other comment pointed out there are still some differences.

If you want a method other than findcontrol try the following:

 GridViewRow row = Gridview1.SelectedRow;
 int CustomerId = int.parse(row.Cells[0].Text);// to get the column value
 CheckBox checkbox1= row.Cells[0].Controls[0] as CheckBox; // you can access the controls like this

You're calling write_file with arguments like this:

write_file(foo, bar)

But you haven't defined 'foo' correctly, or you have a typo in your code so that it's creating a new empty variable and passing it in.

You should use the ClearContents method if you want to clear the content but preserve the formatting.

Worksheets("Sheet1").Range("A1:G37").ClearContents

The Good News is:

It's 100% working.

Just add something inside the script tag such as alert('voila!');. The right question you might want to ask perhaps, "Why didn't I see it in the DOM?".

Karl Swedberg has made a nice explanation to visitor's comment in jQuery API site. I don't want to repeat all his words, you can read directly there here (I found it hard to navigate through the comments there).

All of jQuery's insertion methods use a domManip function internally to clean/process elements before and after they are inserted into the DOM. One of the things the domManip function does is pull out any script elements about to be inserted and run them through an "evalScript routine" rather than inject them with the rest of the DOM fragment. It inserts the scripts separately, evaluates them, and then removes them from the DOM.

I believe that one of the reasons jQuery does this is to avoid "Permission Denied" errors that can occur in Internet Explorer when inserting scripts under certain circumstances. It also avoids repeatedly inserting/evaluating the same script (which could potentially cause problems) if it is within a containing element that you are inserting and then moving around the DOM.

The next thing is, I'll summarize what's the bad news by using .append() function to add a script.

And The Bad News is..

You can't debug your code.

I'm not joking, even if you add debugger; keyword between the line you want to set as breakpoint, you'll be end up getting only the call stack of the object without seeing the breakpoint on the source code, (not to mention that this keyword only works in webkit browser, all other major browsers seems to omit this keyword).

If you fully understand what your code does, than this will be a minor drawback. But if you don't, you will end up adding a debugger; keyword all over the place just to find out what's wrong with your (or my) code. Anyway, there's an alternative, don't forget that javascript can natively manipulate HTML DOM.

Workaround.

Use javascript (not jQuery) to manipulate HTML DOM

If you don't want to lose debugging capability, than you can use javascript native HTML DOM manipulation. Consider this example:

var script   = document.createElement("script");
script.type  = "text/javascript";
script.src   = "path/to/your/javascript.js";    // use this for linked script
script.text  = "alert('voila!');"               // use this for inline script
document.body.appendChild(script);

There it is, just like the old days isn't it. And don't forget to clean things up whether in the DOM or in the memory for all object that's referenced and not needed anymore to prevent memory leaks. You can consider this code to clean things up:

document.body.removechild(document.body.lastChild);
delete UnusedReferencedObjects; // replace UnusedReferencedObject with any object you created in the script you load.

The drawback from this workaround is that you may accidentally add a duplicate script, and that's bad. From here you can slightly mimic .append() function by adding an object verification before adding, and removing the script from the DOM right after it was added. Consider this example:

function AddScript(url, object){
    if (object != null){
        // add script
        var script   = document.createElement("script");
        script.type  = "text/javascript";
        script.src   = "path/to/your/javascript.js";
        document.body.appendChild(script);

        // remove from the dom
        document.body.removeChild(document.body.lastChild);
        return true;
    } else {
        return false;
    };
};

function DeleteObject(UnusedReferencedObjects) {
    delete UnusedReferencedObjects;
}

This way, you can add script with debugging capability while safe from script duplicity. This is just a prototype, you can expand for whatever you want it to be. I have been using this approach and quite satisfied with this. Sure enough I will never use jQuery .append() to add a script.

task deleteJar(type: Delete) {
    delete 'libs/mylibrary.jar'
}           

task exportjar(type: Copy) {
    from('build/intermediates/compile_library_classes/release/')
    into('libs/')
    include('classes.jar')
    rename('classes.jar', 'mylibrary.jar')
}

exportjar.dependsOn(deleteJar, build)

I thought i'd expand on the above answer by talking about how you'd fit modules together into an application. I'd read about this in the doug crockford book but being new to javascript it was all still a bit mysterious.

I come from a c# background so have added some terminology I find useful from there.

Html

You'll have some kindof top level html file. It helps to think of this as your project file. Every javascript file you add to the project wants to go into this, unfortunately you dont get tool support for this (I'm using IDEA).

You need add files to the project with script tags like this:

        <script type="text/javascript" src="app/native/MasterFile.js" /></script>
        <script type="text/javascript" src="app/native/SomeComponent.js" /></script>

It appears collapsing the tags causes things to fail - whilst it looks like xml it's really something with crazier rules!

Namespace file

MasterFile.js

myAppNamespace = {};

that's it. This is just for adding a single global variable for the rest of our code to live in. You could also declare nested namespaces here (or in their own files).

Module(s)

SomeComponent.js

myAppNamespace.messageCounter= (function(){

    var privateState = 0;

    var incrementCount = function () {
        privateState += 1;
    };

    return function (message) {
        incrementCount();
        //TODO something with the message! 
    }
})();

What we're doing here is assigning a message counter function to a variable in our application. It's a function which returns a function which we immediately execute.

Concepts

I think it helps to think of the top line in SomeComponent as being the namespace where you are declaring something. The only caveat to this is all your namespaces need to appear in some other file first - they are just objects rooted by our application variable.

I've only taken minor steps with this at the moment (i'm refactoring some normal javascript out of an extjs app so I can test it) but it seems quite nice as you can define little functional units whilst avoiding the quagmire of 'this'.

You can also use this style to define constructors by returning a function which returns an object with a collection of functions and not calling it immediately.

For anyone like me that was trying to do this via a drush (Drupal shell) command on a remote server, you will not be able to use the solution that requires you to CD into the working directory:

Instead you need to use the solution that breaks up the pull into a fetch & merge:

drush @remote exec git --git-dir=/REPO/PATH --work-tree=/REPO/WORKDIR-PATH fetch origin
drush @remote exec git --git-dir=/REPO/PATH --work-tree=/REPO/WORKDIR-PATH merge origin/branch

If you want to save data that is derived from a Javascript canvas.toDataURL() function, you have to convert blanks into plusses. If you do not do that, the decoded data is corrupted:

<?php
  $encodedData = str_replace(' ','+',$encodedData);
  $decocedData = base64_decode($encodedData);
?>

http://php.net/manual/ro/function.base64-decode.php

Also think about using

$(document).ready(function() {});

Don't know why no one here came up with this yet (kinda sad). When do you execute your code??? Right at the start? Then you might want to use upper mentioned ready() function so your code is being executed after the whole page (with all it's dom elements) has been loaded and not before! Of course this is useless if you run some code that adds dom elements after page load! Then you simply want to wait for those functions and execute your code afterwards...

Fastest approach is the traditional for loop. Here is a more comprehensive performance comparison.

https://gists.cwidanage.com/2019/11/how-to-iterate-over-javascript-arrays.html

You never call varsObject.setNum();

Without a backslash, special characters have a natural special meaning. With a backslash they print as they appear.

\   -   escape the next character
"   -   start or end of string
’   -   start or end a character constant
%   -   start a format specification
\\  -   print a backslash
\"  -   print a double quote
\’  -   print a single quote
%%  -   print a percent sign

The statement

printf("  \"  "); 

will print you the quotes. You can also print these special characters \a, \b, \f, \n, \r, \t and \v with a (slash) preceeding it.

XAMPP - Port 80 in use by “Unable to open process” with PID 4! 12

run the comment in cmd tasklist

and find which the PID and process name related to this now open window task manager

you can also open window task manager by using CTRL+ALT+DEL

now click on the process tab and find the name which using PID and right click on that and end process

now again restart the xampp

== is a bash-specific alias for = and it performs a string (lexical) comparison instead of a numeric comparison. eq being a numeric comparison of course.

Finally, I usually prefer to use the form if [ "$a" == "$b" ]

I believe the flag --force is what you are really looking for. Just use git branch -d --force <branch_name> to delete the branch forcibly.

To be more C# like, define the Nullable type like this:

type Nullable<T> = T | null;

interface Employee{
   id: number;
   name: string;
   salary: Nullable<number>;
}

Bonus:

To make Nullable behave like a built in Typescript type, define it in a global.d.ts definition file in the root source folder. This path worked for me: /src/global.d.ts

You just need to add three file and two css links. You can either cdn's as well. Links for the js files and css files are as such :-

1. jQuery.dataTables.min.js
2. dataTables.bootstrap.min.js
3. dataTables.bootstrap.min.css
4. bootstrap-datepicker.css
5. bootstrap-datepicker.js

They are valid if you are using bootstrap in your project.

-Xmn : the size of the heap for the young generation Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor" .

For Binary Search, T(N) = T(N/2) + O(1) // the recurrence relation

Apply Masters Theorem for computing Run time complexity of recurrence relations : T(N) = aT(N/b) + f(N)

Here, a = 1, b = 2 => log (a base b) = 1

also, here f(N) = n^c log^k(n) //k = 0 & c = log (a base b)

So, T(N) = O(N^c log^(k+1)N) = O(log(N))

Try below code to get currently loaded product id:

$product_id = $this->getProduct()->getId();

When you don’t have access to $this, you can use Magento registry:

$product_id = Mage::registry('current_product')->getId();

Also for product type i think

$product = Mage::getModel('catalog/product')->load($product_id); 

$productType = $product->getTypeId();

Everything is very simple

I went over most of the answers here and none of them gave me the right user name.

In my case I wanted to get the logged in user name, while running my app from a different user, like when shift+right click on a file and "Run as a different user".

The answers I tried gave me the 'other' username.

This blog post supplies a way to get the logged in user name, which works even in my scenario:

This is a variation to get all checked checkboxes in all_location_id without using an "if" statement

var all_location_id = document.querySelectorAll('input[name="location[]"]:checked');

var aIds = [];

for(var x = 0, l = all_location_id.length; x < l;  x++)
{
    aIds.push(all_location_id[x].value);
}

var str = aIds.join(', ');

console.log(str);

Do you mean just? alert()

function hello_world(){ alert("hello world"); }

Add an event handler for the Control.DoubleClick event for your ListBox, and in that event handler open up a MessageBox displaying the selected item.

E.g.:

 private void ListBox1_DoubleClick(object sender, EventArgs e)
 {
     if (ListBox1.SelectedItem != null)
     {
         MessageBox.Show(ListBox1.SelectedItem.ToString());
     }
 }

Where ListBox1 is the name of your ListBox.

Note that you would assign the event handler like this:

ListBox1.DoubleClick += new EventHandler(ListBox1_DoubleClick);

WPF
Pretty much the same as above, but you'd use the MouseDoubleClick event instead:

ListBox1.MouseDoubleClick += new RoutedEventHandler(ListBox1_MouseDoubleClick);

And the event handler:

 private void ListBox1_MouseDoubleClick(object sender, RoutedEventArgs e)
 {
     if (ListBox1.SelectedItem != null)
     {
         MessageBox.Show(ListBox1.SelectedItem.ToString());
     }
 }

Edit: Sisya's answer checks to see if the double-click occurred over an item, which would need to be incorporated into this code to fix the issue mentioned in the comments (MessageBox shown if ListBox is double-clicked while an item is selected, but not clicked over an item).

Hope this helps!

• With Jenkins CLI you do not have to reload everything - you just can load the job (update-job command). You can't use tokens with CLI, AFAIK - you have to use password or password file.

• Token name for user can be obtained via http://<jenkins-server>/user/<username>/configure - push on 'Show API token' button.

• Here's a link on how to use API tokens (it uses wget, but curl is very similar).

I use Github Desktop for Windows and I wanted to move location of a repository. No problem if you move your directory and choose the new location in the software. But if you set a bad directory, you get a fatal error and no second chance to make a relocation to the good one. So to repair that. You must copy project files in the bad directory, make its reconize by Github Desktop, after that, you can move again your project in another folder and make a relocate in the software. No need to close Github Desktop for that, it will check folders in live.

Hoping this will help someone.

In my case (backend), I was using res.send(token);

Everything got fixed when I changed to res.send(data);

You may want to check this if everything is working and posting as intended, but the error keeps popping up in your front-end.

The Google Style Guide for HTML recommends omitting all optional tags.
That includes <html>, <head>, <body>, <p> and <li>.

https://google.github.io/styleguide/htmlcssguide.html#Optional_Tags

For file size optimization and scannability purposes, consider omitting optional tags. The HTML5 specification defines what tags can be omitted.

(This approach may require a grace period to be established as a wider guideline as it’s significantly different from what web developers are typically taught. For consistency and simplicity reasons it’s best served omitting all optional tags, not just a selection.)

You should run this command from within your d:\study folder. It will delete all subfolders which are older than 10 days.

The /S /Q after the rd makes it delete folders even if they are not empty, without prompting.

I suggest you put the above command into a .bat file, and save it as d:\study\cleanup.bat.

It's worth mentioning that you can specify argument ranges with this syntax.

function example() {
    echo "line1 ${@:1:1}"; #First argument
    echo "line2 ${@:2:1}"; #Second argument
    echo "line3 ${@:3}"; #Third argument onwards
}

I hadn't seen it mentioned.

Click here this is a good tutorial for both window/ubuntu.

1. apktool1.5.1.jar download from here.

2. apktool-install-linux-r05-ibot download from here.

3. dex2jar-0.0.9.15.zip download from here.

4. jd-gui-0.3.3.linux.i686.tar.gz (java de-complier) download from here.

5. framework-res.apk ( Located at your android device /system/framework/)

Procedure:

1. Rename the .apk file and change the extension to .zip ,

it will become .zip.

2. Then extract .zip.

3. Unzip downloaded dex2jar-0.0.9.15.zip file , copy the contents and paste it to unzip folder.

4. Open terminal and change directory to unzip “dex2jar-0.0.9.15 “

– cd – sh dex2jar.sh classes.dex (result of this command “classes.dex.dex2jar.jar” will be in your extracted folder itself).

5. Now, create new folder and copy “classes.dex.dex2jar.jar” into it.

6. Unzip “jd-gui-0.3.3.linux.i686.zip“ and open up the “Java Decompiler” in full screen mode.

7. Click on open file and select “classes.dex.dex2jar.jar” into the window.

8. “Java Decompiler” and go to file > save and save the source in a .zip file.

9. Create “source_code” folder.

10. Extract the saved .zip and copy the contents to “source_code” folder.

11. This will be where we keep your source code.

12. Extract apktool1.5.1.tar.bz2 , you get apktool.jar

13. Now, unzip “apktool-install-linux-r05-ibot.zip”

14. Copy “framework-res.apk” , “.apk” and apktool.jar

15. Paste it to the unzip “apktool-install-linux-r05-ibot” folder (line no 13).

16. Then open terminal and type:

    – cd

    – chown -R : ‘apktool.jar’

    – chown -R : ‘apktool’

    – chown -R : ‘aapt’

    – sudo chmod +x ‘apktool.jar’

    – sudo chmod +x ‘apktool’

    – sudo chmod +x ‘aapt’

    – sudo mv apktool.jar /usr/local/bin

    – sudo mv apktool /usr/local/bin

    – sudo mv aapt /usr/local/bin

    – apktool if framework-res.apk – apktool d .apk

try this with jQuery:

$('body').load( url,[data],[callback] );

conda install jupyterthemes

did not worked for me in Windows. I am using Anaconda.

But,

pip install jupyterthemes

worked in Anaconda Prompt.

Try this npm install bson and npm update

public class Test {
    public static void main(String args[]) {
    String s = "pre/fix/dir1/dir2/dir3/dir4/..";
    String prefix = "pre/fix";
    String[] tokens = s.substring(prefix.length()).split("/");
    for (int i=0; i<tokens.length; i++) {
        System.out.println(tokens[i]);
    }
    }

}

You should be able to create a query with this filter here:

(&(objectClass=user)(sAMAccountName=yourUserName)
  (memberof=CN=YourGroup,OU=Users,DC=YourDomain,DC=com))

and when you run that against your LDAP server, if you get a result, your user "yourUserName" is indeed a member of the group "CN=YourGroup,OU=Users,DC=YourDomain,DC=com

Try and see if this works!

If you use C# / VB.Net and System.DirectoryServices, this snippet should do the trick:

DirectoryEntry rootEntry = new DirectoryEntry("LDAP://dc=yourcompany,dc=com");

DirectorySearcher srch = new DirectorySearcher(rootEntry);
srch.SearchScope = SearchScope.Subtree;

srch.Filter = "(&(objectClass=user)(sAMAccountName=yourusername)(memberOf=CN=yourgroup,OU=yourOU,DC=yourcompany,DC=com))";

SearchResultCollection res = srch.FindAll();

if(res == null || res.Count <= 0) {
    Console.WriteLine("This user is *NOT* member of that group");
} else {
    Console.WriteLine("This user is INDEED a member of that group");
}

Word of caution: this will only test for immediate group memberships, and it will not test for membership in what is called the "primary group" (usually "cn=Users") in your domain. It does not handle nested memberships, e.g. User A is member of Group A which is member of Group B - that fact that User A is really a member of Group B as well doesn't get reflected here.
