You may use the SPOOL command to write the information to a file.

Before executing any command type the following:

SPOOL <output file path>

All commands output following will be written to the output file.

To stop command output writing type

SPOOL OFF

Yes you can. The default location for script files is data/db

If you put any script there you can call it as

load("myjstest.js")      // or 
load("/data/db/myjstest.js")

Here is the JSONP I wrote to share with everyone:

the page to send req

please save the srec below to .html youself
c64.tw/r20/eqDiv/src/fr64.txt
the page to resp, please save the srec below to .jsp youself
c64.tw/r20/eqDiv/src/doFr64.txt

or embedded the code in your page:

function callbackForJsonp(resp) {

var elemDivResp = $("#idForDivResp");
elemDivResp.empty();

try {

    elemDivResp.html($("#idForF1").val() + " + " + $("#idForF2").val() + "<br/>");
    elemDivResp.append(" = " + resp.ans + "<br/>");
    elemDivResp.append(" = " + resp.ans2 + "<br/>");

} catch (e) {

    alert("callbackForJsonp=" + e);

}

}

$(document).ready(function() {

var testUrl = "http://c64.tw/r20/eqDiv/doFr64.jsp?callback=?";

$(document.body).prepend("post to " + testUrl + "<br/><br/>");

$("#idForBtnToGo").click(function() {

    $.ajax({

        url : testUrl,
        type : "POST",

        data : {
            f1 : $("#idForF1").val(),
            f2 : $("#idForF2").val(),
            op : "add"
        },

        dataType : "jsonp",
        crossDomain : true,
        //jsonpCallback : "callbackForJsonp",
        success : callbackForJsonp,

        //success : function(resp) {

        //console.log("Yes, you success");
        //callbackForJsonp(resp);

        //},

        error : function(XMLHttpRequest, status, err) {

            console.log(XMLHttpRequest.status + "\n" + err);
            //alert(XMLHttpRequest.status + "\n" + err);

        }

    });

});

});

You are all messing with the global installations and -path files. Just a little error might damage every project you have ever written, and you will spend the rest of the night trying to get a console.log('hi') to work again.

If you have run npm i typescript --save-dev in your project - just try to run:

npx tsc 

And see if it works before messing with global stuff (unless of course you really know what you are doing)

I met this problem with typescript but forgot to add ts and tsx suffix to resolve entry.

module.exports = {
  ...
  resolve: {
    extensions: ['.js', '.jsx', '.ts', '.tsx'],
  },
};

This does the job for me

You could create a class and use the class when you define all of your future 's that you want (or don't want) to be selected by the CSS.

This would be done by writing

<tr class="unselected">

and then in your css having the lines (and using the text-align command as an example) :

unselected {
  text-align:center;
}



selected {
  text-align:right;
}

This is the way it worked for me:

$.post("/Controller/Action", $("#form").serialize(), function(json) {       
        // handle response
}, "json");

[HttpPost]
public ActionResult TV(MyModel id)
{
    return Json(new { success = true });
}

SELECT owner, table_name
  FROM dba_tables

This is assuming that you have access to the DBA_TABLES data dictionary view. If you do not have those privileges but need them, you can request that the DBA explicitly grants you privileges on that table, or, that the DBA grants you the SELECT ANY DICTIONARY privilege or the SELECT_CATALOG_ROLE role (either of which would allow you to query any data dictionary table). Of course, you may want to exclude certain schemas like SYS and SYSTEM which have large numbers of Oracle tables that you probably don't care about.

Alternatively, if you do not have access to DBA_TABLES, you can see all the tables that your account has access to through the ALL_TABLES view:

SELECT owner, table_name
  FROM all_tables

Although, that may be a subset of the tables available in the database (ALL_TABLES shows you the information for all the tables that your user has been granted access to).

If you are only concerned with the tables that you own, not those that you have access to, you could use USER_TABLES:

SELECT table_name
  FROM user_tables

Since USER_TABLES only has information about the tables that you own, it does not have an OWNER column – the owner, by definition, is you.

Oracle also has a number of legacy data dictionary views-- TAB, DICT, TABS, and CAT for example-- that could be used. In general, I would not suggest using these legacy views unless you absolutely need to backport your scripts to Oracle 6. Oracle has not changed these views in a long time so they often have problems with newer types of objects. For example, the TAB and CAT views both show information about tables that are in the user's recycle bin while the [DBA|ALL|USER]_TABLES views all filter those out. CAT also shows information about materialized view logs with a TABLE_TYPE of "TABLE" which is unlikely to be what you really want. DICT combines tables and synonyms and doesn't tell you who owns the object.

Use the command line parameter -XX:MaxPermSize=128m for a Sun JVM (obviously substituting 128 for whatever size you need).

I solved this by changing owner from root to me on all files on /db dir.

Just do ls -l on that folder, if any of the filer is owned by root just change it to you, using: sudo chown user file

set -x

Prints a trace of simple commands, for commands, case commands, select commands, and arithmetic for commands and their arguments or associated word lists after they are expanded and before they are executed. The value of the PS4 variable is expanded and the resultant value is printed before the command and its expanded arguments.

[source]

Example

set -x
echo `expr 10 + 20 `
+ expr 10 + 20
+ echo 30
30

set +x
echo `expr 10 + 20 `
30

Above example illustrates the usage of set -x. When it is used, above arithmetic expression has been expanded. We could see how a singe line has been evaluated step by step.

• First step expr has been evaluated.
• Second step echo has been evaluated.

Generic answer

The standard "nop" in Python is the pass statement:

try:
    do_something()
except Exception:
    pass

Using except Exception instead of a bare except avoid catching exceptions like SystemExit, KeyboardInterrupt etc.

Python 2

Because of the last thrown exception being remembered in Python 2, some of the objects involved in the exception-throwing statement are being kept live indefinitely (actually, until the next exception). In case this is important for you and (typically) you don't need to remember the last thrown exception, you might want to do the following instead of pass:

try:
    do_something()
except Exception:
    sys.exc_clear()

This clears the last thrown exception.

Python 3

In Python 3, the variable that holds the exception instance gets deleted on exiting the except block. Even if the variable held a value previously, after entering and exiting the except block it becomes undefined again.

If you need symbols keys:

I try to use a union to combine two queries to format the returns you want:

SELECT recordid, startdate, enddate FROM tmp Where enddate is null UNION SELECT recordid, MIN(startdate), MAX(enddate) FROM tmp GROUP BY recordid

But I have no idea if the Union would have great impact on the performance

Here's a simple and clean function that returns the file size.

long get_file_size(char *path)
{
    FILE *fp;
    long size = -1;
    /* Open file for reading */
    fp = fopen(path, "r");
    fseek(fp, 0, SEEK_END);
    size = ftell(fp); 
    fp.close();
    return 
}

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

If you are using the Atom IDE, you can install the node-debugger package.

You could combine the maven-shade-plugin and maven-jar-plugin.

• The maven-shade-plugin packs your classes and all dependencies in a single jar file.
• Configure the maven-jar-plugin to specify the main class of your executable jar (see Set Up The Classpath, chapter "Make The Jar Executable").

Example POM configuration for maven-jar-plugin:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                        <mainClass>com.example.MyMainClass</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>

Finally create the executable jar by invoking:

mvn clean package shade:shade

With PostgreSQL 8.4 or newer there is no need to specify the WITH 1 anymore. The start value that was recorded by CREATE SEQUENCE or last set by ALTER SEQUENCE START WITH will be used (most probably this will be 1).

Reset the sequence:

ALTER SEQUENCE seq RESTART;

Then update the table's ID column:

UPDATE foo SET id = DEFAULT;

One way is to create a DateTime object and use it for formatting:

// or using String.Format:
String.Format("{0:HHmmss}", new DateTime(myTimeSpan.Ticks))

Optional TimeSpan attribute.

Specifies the maximum number of seconds that a request is allowed to execute before being automatically shut down by ASP.NET.

This time-out applies only if the debug attribute in the compilation element is False. To help to prevent shutting down the application while you are debugging, do not set this time-out to a large value.

The default is "00:01:50" (110 seconds).

What are you expecting? The default Tomcat homepage? If so, you'll need to configure Eclipse to take control over from Tomcat.

Doubleclick the Tomcat server entry in the Servers tab, you'll get the server configuration. At the left column, under Server Locations, select Use Tomcat installation (note, when it is grayed out, read the section leading text! ;) ). This way Eclipse will take full control over Tomcat, this way you'll also be able to access the default Tomcat homepage with the Tomcat Manager when running from inside Eclipse. I only don't see how that's useful while developing using Eclipse.

The port number is not the problem. You would otherwise have gotten an exception in Tomcat's startup log, and the browser would show a browser-specific "Connection timed out" error page and thus not a Tomcat-specific error page which could impossibly be served when Tomcat was not up and running.

Here's how i finally created the ~/.android/debug.keystore file.

First some background. I got a new travel laptop. Installed Android Studio. Cloned my android project from git hub. The project would not run. Finally figured out that the debug.keystore was not created ... and i could not figure out how to get Android Studio to create it.

Finally, i created a new blank project ... and that created the debug.keystore!

Hope this helps other who have this problem.

This might work:

^(\*|\d+(\.\d+){0,2}(\.\*)?)$

At the top level, "*" is a special case of a valid version number. Otherwise, it starts with a number. Then there are zero, one, or two ".nn" sequences, followed by an optional ".*". This regex would accept 1.2.3.* which may or may not be permitted in your application.

The code for retrieving the matched sequences, especially the (\.\d+){0,2} part, will depend on your particular regex library.

Just Try this:

def __str__(self):
    return f'Memo={self.memo}, Tag={self.tags}'

.success() only gets called if your webserver responds with a 200 OK HTTP header - basically when everything is fine.

The callbacks attached to done() will be fired when the deferred is resolved. The callbacks attached to fail() will be fired when the deferred is rejected.

.done() has only one callback and it is the success callback

This could be an answer to your question:

JSONArray msg1 = (JSONArray) json.get("source");
for(int i = 0; i < msg1.length(); i++){
  String name = msg1.getString("name");
  int age     = msg1.getInt("age");
}

struct DeviceType {
        static let IS_IPHONE_4_OR_LESS = UIDevice.current.userInterfaceIdiom == .phone && Constants.SCREEN_MAX_LENGTH < 568
        static let IS_IPHONE_5 = UIDevice.current.userInterfaceIdiom == .phone && Constants.SCREEN_MAX_LENGTH == 568
        static let IS_IPHONE_6 = UIDevice.current.userInterfaceIdiom == .phone && Constants.SCREEN_MAX_LENGTH == 667
        static let IS_IPHONE_6P = UIDevice.current.userInterfaceIdiom == .phone && Constants.SCREEN_MAX_LENGTH == 736
        static let IS_IPAD = UIDevice.current.userInterfaceIdiom == .pad && Constants.SCREEN_MAX_LENGTH == 1024
    }

This also seems to work:

while "  " in s:
    s = s.replace("  ", " ")

Where the variable s represents your string.

To illustrate the need for move semantics, let's consider this example without move semantics:

Here's a function that takes an object of type T and returns an object of the same type T:

T f(T o) { return o; }
  //^^^ new object constructed

The above function uses call by value which means that when this function is called an object must be constructed to be used by the function.
Because the function also returns by value, another new object is constructed for the return value:

T b = f(a);
  //^ new object constructed

Two new objects have been constructed, one of which is a temporary object that's only used for the duration of the function.

When the new object is created from the return value, the copy constructor is called to copy the contents of the temporary object to the new object b. After the function completes, the temporary object used in the function goes out of scope and is destroyed.

Now, let's consider what a copy constructor does.

It must first initialize the object, then copy all the relevant data from the old object to the new one.
Depending on the class, maybe its a container with very much data, then that could represent much time and memory usage

// Copy constructor
T::T(T &old) {
    copy_data(m_a, old.m_a);
    copy_data(m_b, old.m_b);
    copy_data(m_c, old.m_c);
}

With move semantics it's now possible to make most of this work less unpleasant by simply moving the data rather than copying.

// Move constructor
T::T(T &&old) noexcept {
    m_a = std::move(old.m_a);
    m_b = std::move(old.m_b);
    m_c = std::move(old.m_c);
}

Moving the data involves re-associating the data with the new object. And no copy takes place at all.

This is accomplished with an rvalue reference.
An rvalue reference works pretty much like an lvalue reference with one important difference:
an rvalue reference can be moved and an lvalue cannot.

From cppreference.com:

To make strong exception guarantee possible, user-defined move constructors should not throw exceptions. In fact, standard containers typically rely on std::move_if_noexcept to choose between move and copy when container elements need to be relocated. If both copy and move constructors are provided, overload resolution selects the move constructor if the argument is an rvalue (either a prvalue such as a nameless temporary or an xvalue such as the result of std::move), and selects the copy constructor if the argument is an lvalue (named object or a function/operator returning lvalue reference). If only the copy constructor is provided, all argument categories select it (as long as it takes a reference to const, since rvalues can bind to const references), which makes copying the fallback for moving, when moving is unavailable. In many situations, move constructors are optimized out even if they would produce observable side-effects, see copy elision. A constructor is called a 'move constructor' when it takes an rvalue reference as a parameter. It is not obligated to move anything, the class is not required to have a resource to be moved and a 'move constructor' may not be able to move a resource as in the allowable (but maybe not sensible) case where the parameter is a const rvalue reference (const T&&).

Type type = typeof(MessageProcessor<>).MakeGenericType(key);

That's the best you can do, however without actually knowing what type it is, there's really not much more you can do with it.

EDIT: I should clarify. I changed from var type to Type type. My point is, now you can do something like this:

object obj = Activator.CreateInstance(type);

obj will now be the correct type, but since you don't know what type "key" is at compile time, there's no way to cast it and do anything useful with it.

May be this helps some one who are looking for multiple date formats one after the other by willingly or unexpectedly. Please find the code: I am using moment.js format function on a current date as (today is 29-06-2020) var startDate = moment(new Date()).format('MM/DD/YY'); Result: 06/28/20

what happening is it retains only the year part :20 as "06/28/20", after If I run the statement : new Date(startDate) The result is "Mon Jun 28 1920 00:00:00 GMT+0530 (India Standard Time)",

Then, when I use another format on "06/28/20": startDate = moment(startDate ).format('MM-DD-YYYY'); Result: 06-28-1920, in google chrome and firefox browsers it gives correct date on second attempt as: 06-28-2020. But in IE it is having issues, from this I understood we can apply one dateformat on the given date, If we want second date format, it should be apply on the fresh date not on the first date format result. And also observe that for first time applying 'MM-DD-YYYY' and next 'MM-DD-YY' is working in IE. For clear understanding please find my question in the link: Date went wrong when using Momentjs date format in IE 11

For exe files, I suppose the differences are nearly unimportant.
But to start an exe you don't even need CALL.

When starting another batch it's a big difference,
as CALL will start it in the same window and the called batch has access to the same variable context.
So it can also change variables which affects the caller.

START will create a new cmd.exe for the called batch and without /b it will open a new window.
As it's a new context, variables can't be shared.

Differences

Using start /wait <prog>
- Changes of environment variables are lost when the <prog> ends
- The caller waits until the <prog> is finished

Using call <prog>
- For exe it can be ommited, because it's equal to just starting <prog>
- For an exe-prog the caller batch waits or starts the exe asynchronous, but the behaviour depends on the exe itself.
- For batch files, the caller batch continues, when the called <batch-file> finishes, WITHOUT call the control will not return to the caller batch

Addendum:

Using CALL can change the parameters (for batch and exe files), but only when they contain carets or percent signs.

call myProg param1 param^^2 "param^3" %%path%%

Will be expanded to (from within an batch file)

myProg param1 param2 param^^3 <content of path>

Here goes my humble attempt to explain the concept to newbies around the world: (a color coded version on my blog too)

A lot of people run to a lone phone booth (they don't have mobile phones) to talk to their loved ones. The first person to catch the door-handle of the booth, is the one who is allowed to use the phone. He has to keep holding on to the handle of the door as long as he uses the phone, otherwise someone else will catch hold of the handle, throw him out and talk to his wife :) There's no queue system as such. When the person finishes his call, comes out of the booth and leaves the door handle, the next person to get hold of the door handle will be allowed to use the phone.

A thread is : Each person
The mutex is : The door handle
The lock is : The person's hand
The resource is : The phone

Any thread which has to execute some lines of code which should not be modified by other threads at the same time (using the phone to talk to his wife), has to first acquire a lock on a mutex (clutching the door handle of the booth). Only then will a thread be able to run those lines of code (making the phone call).

Once the thread has executed that code, it should release the lock on the mutex so that another thread can acquire a lock on the mutex (other people being able to access the phone booth).

[The concept of having a mutex is a bit absurd when considering real-world exclusive access, but in the programming world I guess there was no other way to let the other threads 'see' that a thread was already executing some lines of code. There are concepts of recursive mutexes etc, but this example was only meant to show you the basic concept. Hope the example gives you a clear picture of the concept.]

With C++11 threading:

#include <iostream>
#include <thread>
#include <mutex>

std::mutex m;//you can use std::lock_guard if you want to be exception safe
int i = 0;

void makeACallFromPhoneBooth() 
{
    m.lock();//man gets a hold of the phone booth door and locks it. The other men wait outside
      //man happily talks to his wife from now....
      std::cout << i << " Hello Wife" << std::endl;
      i++;//no other thread can access variable i until m.unlock() is called
      //...until now, with no interruption from other men
    m.unlock();//man lets go of the door handle and unlocks the door
}

int main() 
{
    //This is the main crowd of people uninterested in making a phone call

    //man1 leaves the crowd to go to the phone booth
    std::thread man1(makeACallFromPhoneBooth);

Compile and run using g++ -std=c++0x -pthread -o thread thread.cpp;./thread

Instead of explicitly using lock and unlock, you can use brackets as shown here, if you are using a scoped lock for the advantage it provides. Scoped locks have a slight performance overhead though.

Try this:

import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URL;
import javax.imageio.ImageIO;

public class WriteImage 
{   
    public static void main( String[] args )
    {
        BufferedImage image = null;
        try {

            URL url = new URL("URL_IMAGE");
            image = ImageIO.read(url);

            ImageIO.write(image, "jpg",new File("C:\\out.jpg"));
            ImageIO.write(image, "gif",new File("C:\\out.gif"));
            ImageIO.write(image, "png",new File("C:\\out.png"));

        } catch (IOException e) {
            e.printStackTrace();
        }
        System.out.println("Done");
    }
}

Here's an upstart solution I've been using for my personal projects:

Place it in /etc/init/node_app_daemon.conf:

description "Node.js Daemon"
author      "Adam Eberlin"

stop on shutdown

respawn
respawn limit 3 15

script
  export APP_HOME="/srv/www/MyUserAccount/server"
  cd $APP_HOME
  exec sudo -u user /usr/bin/node server.js
end script

This will also handle respawning your application in the event that it crashes. It will give up attempts to respawn your application if it crashes 3 or more times in less than 15 seconds.

The following should work for a JSON returned string. It will also work for an associative array of data.

for (var key in data)
     alert(key + ' is ' + data[key]);

You can do this

@Html.DropDownList("Sortby", new SelectListItem[] { new SelectListItem() 
  { 

       Text = "Newest to Oldest", Value = "0" }, new SelectListItem() { Text = "Oldest to Newest", Value = "1" } , new
       {
           onchange = @"form.submit();"
       }
})

Microsoft Visual Studio is funny when your using the installer you MUST checkbox a-lot of options to bypass the .netframework(somewhat) to make more c++ instead of c sharp applications, such as the clr options under dekstop development... in visual studio installer.... difference is c++ win32 console project or a c++ CLR console project. So whats the difference? Well i'm not going to list all of the files CLR includes but since most good c++ kernals are in linux... so CLR allows you to bypass a-lot of the windows .netframework b/c visual studio was really meant for you to make apps in C sharp.

Heres a C++ win32 console project!

#include "stdafx.h"
#include <iostream>
using namespace std;
int main( )
{
cout<<"Hello World"<<endl;
return 0;
}

Now heres a c++ CLR console project!

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
Console::WriteLine("Hello World");
return 0;
}

Both programs do the same thing .... CLR just looks more frameworked class overloading methodology so microsoft can great it's own vast library you should familiarize yourself w/ if so inclined. https://msdn.microsoft.com/en-us/library/2e6a4at9.aspx

other things you'll learn from debugging to add for error avoidance

#ifdef _MRC_VER
#define _CRT_SECURE_NO_WARNINGS
#endif

If you don't want to open Android Studio just to modify your path...

They live here with a default installation:

${HOME}/Library/Android/sdk/tools
${HOME}/Library/Android/sdk/platform-tools

Here's what you want to add to your .bashwhatever

export PATH="${HOME}/Library/Android/sdk/tools:${HOME}/Library/Android/sdk/platform-tools:${PATH}"

If you don't want to block the current thread by waiting/checking for the other running thread completion, you can implement callback method like this.

Action onCompleted = () => 
{  
    //On complete action
};

var thread = new Thread(
  () =>
  {
    try
    {
      // Do your work
    }
    finally
    {
      onCompleted();
    }
  });
thread.Start();

If you are dealing with controls that doesn't support cross-thread operation, then you have to invoke the callback method

this.Invoke(onCompleted);

All u need do is to change the lowercase 'hh' in the pattern to an uppercase letter 'HH'

for Kotlin:

val sdf = SimpleDateFormat("yyyy-MM-dd HH:mm:ss") val currentDate = sdf.format(Date())

for java:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-ddHH:mm:ss") Date currentDate = sdf.format(new Date())

My implementation)

const items = Array.from(document.querySelectorAll('.item'));_x000D_
items.forEach(item =>{_x000D_
    item.style.color = checkEllipsis(item) ? 'red': 'black'_x000D_
})_x000D_
_x000D_
function checkEllipsis(el){_x000D_
  const styles = getComputedStyle(el);_x000D_
  const widthEl = parseFloat(styles.width);_x000D_
  const ctx = document.createElement('canvas').getContext('2d');_x000D_
  ctx.font = `${styles.fontSize} ${styles.fontFamily}`;_x000D_
  const text = ctx.measureText(el.innerText);_x000D_
  return text.width > widthEl;_x000D_
}

.item{_x000D_
  width: 60px;_x000D_
  overflow: hidden;_x000D_
  text-overflow: ellipsis;_x000D_
}

      <div class="item">Short</div>_x000D_
      <div class="item">Loooooooooooong</div>

For completeness, there're actually three ways to set the encoding when connecting to MySQL from PDO and which ones are available depend on your PHP version. The order of preference would be:

1. charset parameter in the DSN string
2. Run SET NAMES utf8 with PDO::MYSQL_ATTR_INIT_COMMAND connection option
3. Run SET NAMES utf8 manually

This sample code implements all three:

<?php

define('DB_HOST', 'localhost');
define('DB_SCHEMA', 'test');
define('DB_USER', 'test');
define('DB_PASSWORD', 'test');
define('DB_ENCODING', 'utf8');


$dsn = 'mysql:host=' . DB_HOST . ';dbname=' . DB_SCHEMA;
$options = array(
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
);

if( version_compare(PHP_VERSION, '5.3.6', '<') ){
    if( defined('PDO::MYSQL_ATTR_INIT_COMMAND') ){
        $options[PDO::MYSQL_ATTR_INIT_COMMAND] = 'SET NAMES ' . DB_ENCODING;
    }
}else{
    $dsn .= ';charset=' . DB_ENCODING;
}

$conn = @new PDO($dsn, DB_USER, DB_PASSWORD, $options);

if( version_compare(PHP_VERSION, '5.3.6', '<') && !defined('PDO::MYSQL_ATTR_INIT_COMMAND') ){
    $sql = 'SET NAMES ' . DB_ENCODING;
    $conn->exec($sql);
}

Doing all three is probably overkill (unless you're writing a class you plan to distribute or reuse).

If you just need to go from BitmapImage to Bitmap it's quite easy,

private Bitmap BitmapImage2Bitmap(BitmapImage bitmapImage)
    {
        return new Bitmap(bitmapImage.StreamSource);
    }

On Ubuntu, hostname command can be used with the following options:

• -i, --ip-address addresses for the host name
• -I, --all-ip-addresses all addresses for the host

For example:

$ hostname -i
172.17.0.2

To assign to the variable, the following one-liner can be used:

IP=$(hostname -i)

I needed to do a query to get me all groups with a managedBy value set (not empty) and this gave some nice results:

(!(!managedBy=*))

This makes it possible to show any wanted layout previously hidden by the keyboard.

Add this to the activity tag in AndroidManifest.xml

android:windowSoftInputMode="adjustResize"

Surround your root view with a ScrollView, preferably with scrollbars=none. The ScrollView will properly not change any thing with your layout except be used to solve this problem.

And then set fitsSystemWindows="true" on the view that you want to make fully shown above the keyboard. This will make your EditText visible above the keyboard, and make it possible to scroll down to the parts below the EditText but in the view with fitsSystemWindows="true".

android:fitsSystemWindows="true"

For example:

<ScrollView
    android:id="@+id/scrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="none">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true">

        ...

    </android.support.constraint.ConstraintLayout>
</ScrollView>   

If you want to show the full part of fitsSystemWindows="true" view above the keyboard in the moment the keyboard appears, you will need some code to scroll the view to the bottom:

// Code is in Kotlin

setupKeyboardListener(scrollView) // call in OnCreate or similar


private fun setupKeyboardListener(view: View) {
    view.viewTreeObserver.addOnGlobalLayoutListener {
        val r = Rect()
        view.getWindowVisibleDisplayFrame(r)
        if (Math.abs(view.rootView.height - (r.bottom - r.top)) > 100) { // if more than 100 pixels, its probably a keyboard...
            onKeyboardShow()
        }
    }
}

private fun onKeyboardShow() {
    scrollView.scrollToBottomWithoutFocusChange()
}

fun ScrollView.scrollToBottomWithoutFocusChange() { // Kotlin extension to scrollView
    val lastChild = getChildAt(childCount - 1)
    val bottom = lastChild.bottom + paddingBottom
    val delta = bottom - (scrollY + height)
    smoothScrollBy(0, delta)
}

I can use pointers, but I am a bit afraid of using them.

If you need a dynamic array, you can't escape pointers. Why are you afraid though? They won't bite (as long as you're careful, that is). There's no built-in dynamic array in C, you'll just have to write one yourself. In C++, you can use the built-in std::vector class. C# and just about every other high-level language also have some similar class that manages dynamic arrays for you.

If you do plan to write your own, here's something to get you started: most dynamic array implementations work by starting off with an array of some (small) default size, then whenever you run out of space when adding a new element, double the size of the array. As you can see in the example below, it's not very difficult at all: (I've omitted safety checks for brevity)

typedef struct {
  int *array;
  size_t used;
  size_t size;
} Array;

void initArray(Array *a, size_t initialSize) {
  a->array = malloc(initialSize * sizeof(int));
  a->used = 0;
  a->size = initialSize;
}

void insertArray(Array *a, int element) {
  // a->used is the number of used entries, because a->array[a->used++] updates a->used only *after* the array has been accessed.
  // Therefore a->used can go up to a->size 
  if (a->used == a->size) {
    a->size *= 2;
    a->array = realloc(a->array, a->size * sizeof(int));
  }
  a->array[a->used++] = element;
}

void freeArray(Array *a) {
  free(a->array);
  a->array = NULL;
  a->used = a->size = 0;
}

Using it is just as simple:

Array a;
int i;

initArray(&a, 5);  // initially 5 elements
for (i = 0; i < 100; i++)
  insertArray(&a, i);  // automatically resizes as necessary
printf("%d\n", a.array[9]);  // print 10th element
printf("%d\n", a.used);  // print number of elements
freeArray(&a);

In response to your postscript, that depends on what you would like.

You are getting (possible) multiple rows for each row in your left table because there are multiple matches for the join condition. If you want your total results to have the same number of rows as there is in the left part of the query you need to make sure your join conditions cause a 1-to-1 match.

Alternatively, depending on what you actually want you can use aggregate functions (if for example you just want a string from the right part you could generate a column that is a comma delimited string of the right side results for that left row.

If you are only looking at 1 or 2 columns from the outer join you might consider using a scalar subquery since you will be guaranteed 1 result.

Use the range type. If the user enter a date:

select *
from table
where
    update_date
    <@
    tsrange('2013-05-03', '2013-05-03'::date + 1, '[)');

If the user enters timestamps then you don't need the ::date + 1 part

GISTS The Gist is an outstanding service provided by GitHub. Using this service, you can share your work publically or privately. You can share a single file, articles, full applications or source code etc.

The GitHub is much more than just Gists. It provides immense services to group together a project or programs digital resources in a centralized location called repository and share among stakeholder. The GitHub repository will hold or maintain the multiple version of the files or history of changes and you can retrieve a specific version of a file when you want. Whereas gist will create each post as a new repository and will maintain the history of the file.

Mostly we write below statement select * from table where length(ltrim(rtrim(field)))=10;

My simple solution is this

if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) ==
        PackageManager.PERMISSION_GRANTED &&
        ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) ==
        PackageManager.PERMISSION_GRANTED) {
    googleMap.setMyLocationEnabled(true);
    googleMap.getUiSettings().setMyLocationButtonEnabled(true);
} else {
    Toast.makeText(this, R.string.error_permission_map, Toast.LENGTH_LONG).show();
}

or you can open permission dialog in else like this

} else {
   ActivityCompat.requestPermissions(this, new String[] {
      Manifest.permission.ACCESS_FINE_LOCATION, 
      Manifest.permission.ACCESS_COARSE_LOCATION }, 
      TAG_CODE_PERMISSION_LOCATION);
}

There is a tool from Microsoft to convert java to C#. For the opposite direction take a look here and here. If this doesn't work out, it should not take too long to convert the source manually because C# and java are very similar,

I had the best luck combining two of the answers above. Navigate to the site in Chrome, then find the request on the Network tab of DevTools. Right click the request and Copy, but Copy as fetch instead of cURL. You can paste the fetch code directly into the DevTools console and edit it, instead of using the command line.

EDIT: I had not realized this was about the data format. You could use

import pandas as pd
import scipy
two_data = pd.DataFrame(data, index=data['Category'])

Then accessing the categories is as simple as

scipy.stats.ttest_ind(two_data.loc['cat'], two_data.loc['cat2'], equal_var=False)

The loc operator accesses rows by label.

As @G Garcia said

one sided or two sided dependent or independent

If you have two independent samples but you do not know that they have equal variance, you can use Welch's t-test. It is as simple as

scipy.stats.ttest_ind(cat1['values'], cat2['values'], equal_var=False)

For reasons to prefer Welch's test, see https://stats.stackexchange.com/questions/305/when-conducting-a-t-test-why-would-one-prefer-to-assume-or-test-for-equal-vari.

For two dependent samples, you can use

scipy.stats.ttest_rel(cat1['values'], cat2['values'])

Just try beeprint

it prints something like this:

instance(Animal):
    legs: 2,
    name: 'Dog',
    color: 'Spotted',
    smell: 'Alot',
    age: 10,
    kids: 0,

I think is exactly what you need.

childform = new Child();
childform.Show(this);

In event childform load

this.CenterToParent();

typedef union{
    float a;
    char b[4];
} my_union_t;

You can access to float data value byte by byte and send it through 8-bit output buffer (e.g. USART) without casting.

you can use call back function, like this

  $this->form_validation->set_rules('userfile', 'Document', 'callback_file_selected_test');

    if ($this->form_validation->run() == FALSE) {
         //error
     }
    else{
           // success       
      }

function file_selected_test(){

    $this->form_validation->set_message('file_selected_test', 'Please select file.');
    if (empty($_FILES['userfile']['name'])) {
            return false;
        }else{
            return true;
        }
}

I am working on DOM Keyboard Event Level 3 polyfill . In latest browsers or with this polyfill you can do something like this:

element.addEventListener("keydown", function(e){ console.log(e.key, e.char, e.keyCode) })

var e = new KeyboardEvent("keydown", {bubbles : true, cancelable : true, key : "Q", char : "Q", shiftKey : true});
element.dispatchEvent(e);

//If you need legacy property "keyCode"
// Note: In some browsers you can't overwrite "keyCode" property. (At least in Safari)
delete e.keyCode;
Object.defineProperty(e, "keyCode", {"value" : 666})

UPDATE:

Now my polyfill supports legacy properties "keyCode", "charCode" and "which"

var e = new KeyboardEvent("keydown", {
    bubbles : true,
    cancelable : true,
    char : "Q",
    key : "q",
    shiftKey : true,
    keyCode : 81
});

Examples here

Additionally here is cross-browser initKeyboardEvent separately from my polyfill: (gist)

If the verification logic is non-trivial, it will be messy to write a large lambda method (as your example shows). You could put all the test statements in a separate method, but I don't like to do this because it disrupts the flow of reading the test code.

Another option is to use a callback on the Setup call to store the value that was passed into the mocked method, and then write standard Assert methods to validate it. For example:

// Arrange
MyObject saveObject;
mock.Setup(c => c.Method(It.IsAny<int>(), It.IsAny<MyObject>()))
        .Callback<int, MyObject>((i, obj) => saveObject = obj)
        .Returns("xyzzy");

// Act
// ...

// Assert
// Verify Method was called once only
mock.Verify(c => c.Method(It.IsAny<int>(), It.IsAny<MyObject>()), Times.Once());
// Assert about saveObject
Assert.That(saveObject.TheProperty, Is.EqualTo(2));

View Custmv;

 private void initViews() {
        inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        Custmv = inflater.inflate(R.layout.id_number_edit_text_custom, this, true);
        editText = (EditText) findViewById(R.id.id_number_custom);
        loadButton = (ImageButton) findViewById(R.id.load_data_button);
        loadButton.setVisibility(RelativeLayout.INVISIBLE);
        loadData();
    }

private void loadData(){
        loadButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                EditText firstName = (EditText) Custmv.getParent().findViewById(R.id.display_name);
                firstName.setText("Some Text");
            }
        });
    }

try like this.

self.automaticallyAdjustsScrollViewInsets = NO;

try, you can deal with it!

From the official Swift programming guide:

Global variables are variables that are defined outside of any function, method, closure, or type context. Global constants and variables are always computed lazily.

You can define it in any file and can access it in current module anywhere. So you can define it somewhere in the file outside of any scope. There is no need for static and all global variables are computed lazily.

 var yourVariable = "someString"

You can access this from anywhere in the current module.

However you should avoid this as Global variables are not good for application state and mainly reason of bugs.

As shown in this answer, in Swift you can encapsulate them in struct and can access anywhere. You can define static variables or constant in Swift also. Encapsulate in struct

struct MyVariables {
    static var yourVariable = "someString"
}

You can use this variable in any class or anywhere

let string = MyVariables.yourVariable
println("Global variable:\(string)")

//Changing value of it
MyVariables.yourVariable = "anotherString"

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

Just updating this question with a more modern wrapper This library wraps Pillow (a fork of PIL) https://pypi.org/project/python-resize-image/

Allowing you to do something like this :-

from PIL import Image
from resizeimage import resizeimage

fd_img = open('test-image.jpeg', 'r')
img = Image.open(fd_img)
img = resizeimage.resize_width(img, 200)
img.save('test-image-width.jpeg', img.format)

Update 2019 - Bootstrap v4.1+

Here's a much more simple way to change the navbar background color.

Just use .navbar-dark instead of .navbar-light and add your custom background color class like .bg-company-red

.navbar-dark will make all your links white.

HTML

<nav class="navbar navbar-dark bg-company-red">

CSS style...

.bg-company-red {
    background-color: darkred !important;
}

See http://getbootstrap.com/docs/4.1/components/navbar/#color-schemes for official documentation.

A basically full command is like git push <remote> <local_ref>:<remote_ref>. If you run just git push, git does not know what to do exactly unless you have made some config that helps git to make a decision. In a git repo, we can setup multiple remotes. Also we can push a local ref to any remote ref. The full command is the most straightforward way to make a push. If you want to type fewer words, you have to config first, like --set-upstream.

A deferred can be used in place of a mutex. This is essentially the same as the multiple ajax usage scenarios.

MUTEX

var mutex = 2;

setTimeout(function() {
 callback();
}, 800);

setTimeout(function() {
 callback();
}, 500);

function callback() {
 if (--mutex === 0) {
  //run code
 }
}

DEFERRED

function timeout(x) {
 var dfd = jQuery.Deferred();
 setTimeout(function() {
  dfd.resolve();
 }, x);
 return dfd.promise();
}

jQuery.when(
timeout(800), timeout(500)).done(function() {
 // run code
});

When using a Deferred as a mutex only, watch out for performance impacts (http://jsperf.com/deferred-vs-mutex/2). Though the convenience, as well as additional benefits supplied by a Deferred is well worth it, and in actual (user driven event based) usage the performance impact should not be noticeable.

If the query's column has an appropriate type then

var dateString = MyReader.GetDateTime(MyReader.GetOrdinal("column")).ToString(myDateFormat)

If the query's column is actually a string then see other answers.

This is fastest way I know of, even though you said you didn't want to use regular expressions:

Regex.Replace(XML, @"\s+", "")

Another way to do this (in modern browsers) is with a negative spread box-shadow. Check out this updated fiddle: http://jsfiddle.net/WuZat/290/

box-shadow: 0px 24px 3px -24px magenta;

I think the safest and most compatible way is the accepted answer above, though. Just thought I'd share another technique.

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

You can use MATCH for instance.

1. Select the column from the first cell, for example cell A2 to cell A100 and insert a conditional formatting, using 'New Rule...' and the option to conditional format based on a formula.

2. In the entry box, put:

   =MATCH(A2, 'Sheet2'!A:A, 0)
   

3. Pick the desired formatting (change the font to red or fill the cell background, etc) and click OK.

MATCH takes the value A2 from your data table, looks into 'Sheet2'!A:A and if there's an exact match (that's why there's a 0 at the end), then it'll return the row number.

Note: Conditional formatting based on conditions from other sheets is available only on Excel 2010 onwards. If you're working on an earlier version, you might want to get the list of 'Don't check' in the same sheet.

EDIT: As per new information, you will have to use some reverse matching. Instead of the above formula, try:

=SUM(IFERROR(SEARCH('Sheet2'!$A$1:$A$44, A2),0))

How to specify the JDK version?

Use any of three ways: (1) Spring Boot feature, or use Maven compiler plugin with either (2) source & target or (3) with release.

Spring Boot

1. <java.version> is not referenced in the Maven documentation.
   It is a Spring Boot specificity.
   It allows to set the source and the target java version with the same version such as this one to specify java 1.8 for both :

   1.8

Feel free to use it if you use Spring Boot.

maven-compiler-plugin with source & target

2. Using maven-compiler-plugin or maven.compiler.source/maven.compiler.target properties are equivalent.

That is indeed :

<plugins>
    <plugin>    
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
    </plugin>
</plugins>

is equivalent to :

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

according to the Maven documentation of the compiler plugin since the <source> and the <target> elements in the compiler configuration use the properties maven.compiler.source and maven.compiler.target if they are defined.

source

The -source argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.source.

target

The -target argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.target.

About the default values for source and target, note that since the 3.8.0 of the maven compiler, the default values have changed from 1.5 to 1.6.

maven-compiler-plugin with release instead of source & target

3. The maven-compiler-plugin 3.6 and later versions provide a new way :

   org.apache.maven.plugins maven-compiler-plugin 3.8.0 9

You could also declare just :

<properties>
    <maven.compiler.release>9</maven.compiler.release>
</properties>

But at this time it will not work as the maven-compiler-plugin default version you use doesn't rely on a recent enough version.

The Maven release argument conveys release : a new JVM standard option that we could pass from Java 9 :

Compiles against the public, supported and documented API for a specific VM version.

This way provides a standard way to specify the same version for the source, the target and the bootstrap JVM options.
Note that specifying the bootstrap is a good practice for cross compilations and it will not hurt if you don't make cross compilations either.

Which is the best way to specify the JDK version?

The first way (<java.version>) is allowed only if you use Spring Boot.

For Java 8 and below :

About the two other ways : valuing the maven.compiler.source/maven.compiler.target properties or using the maven-compiler-plugin, you can use one or the other. It changes nothing in the facts since finally the two solutions rely on the same properties and the same mechanism : the maven core compiler plugin.

Well, if you don't need to specify other properties or behavior than Java versions in the compiler plugin, using this way makes more sense as this is more concise:

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

From Java 9 :

The release argument (third point) is a way to strongly consider if you want to use the same version for the source and the target.

What happens if the version differs between the JDK in JAVA_HOME and which one specified in the pom.xml?

It is not a problem if the JDK referenced by the JAVA_HOME is compatible with the version specified in the pom but to ensure a better cross-compilation compatibility think about adding the bootstrap JVM option with as value the path of the rt.jar of the target version.

An important thing to consider is that the source and the target version in the Maven configuration should not be superior to the JDK version referenced by the JAVA_HOME.
A older version of the JDK cannot compile with a more recent version since it doesn't know its specification.

To get information about the source, target and release supported versions according to the used JDK, please refer to java compilation : source, target and release supported versions.

How handle the case of JDK referenced by the JAVA_HOME is not compatible with the java target and/or source versions specified in the pom?

For example, if your JAVA_HOME refers to a JDK 1.7 and you specify a JDK 1.8 as source and target in the compiler configuration of your pom.xml, it will be a problem because as explained, the JDK 1.7 doesn't know how to compile with.
From its point of view, it is an unknown JDK version since it was released after it.
In this case, you should configure the Maven compiler plugin to specify the JDK in this way :

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <compilerVersion>1.8</compilerVersion>      
        <fork>true</fork>
        <executable>D:\jdk1.8\bin\javac</executable>                
    </configuration>
</plugin>

You could have more details in examples with maven compiler plugin.

It is not asked but cases where that may be more complicated is when you specify source but not target. It may use a different version in target according to the source version. Rules are particular : you can read about them in the Cross-Compilation Options part.

Why the compiler plugin is traced in the output at the execution of the Maven package goal even if you don't specify it in the pom.xml?

To compile your code and more generally to perform all tasks required for a maven goal, Maven needs tools. So, it uses core Maven plugins (you recognize a core Maven plugin by its groupId : org.apache.maven.plugins) to do the required tasks : compiler plugin for compiling classes, test plugin for executing tests, and so for... So, even if you don't declare these plugins, they are bound to the execution of the Maven lifecycle.
At the root dir of your Maven project, you can run the command : mvn help:effective-pom to get the final pom effectively used. You could see among other information, attached plugins by Maven (specified or not in your pom.xml), with the used version, their configuration and the executed goals for each phase of the lifecycle.

In the output of the mvn help:effective-pom command, you could see the declaration of these core plugins in the <build><plugins> element, for example :

...
<plugin>
   <artifactId>maven-clean-plugin</artifactId>
   <version>2.5</version>
   <executions>
     <execution>
       <id>default-clean</id>
       <phase>clean</phase>
       <goals>
         <goal>clean</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-resources-plugin</artifactId>
   <version>2.6</version>
   <executions>
     <execution>
       <id>default-testResources</id>
       <phase>process-test-resources</phase>
       <goals>
         <goal>testResources</goal>
       </goals>
     </execution>
     <execution>
       <id>default-resources</id>
       <phase>process-resources</phase>
       <goals>
         <goal>resources</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.1</version>
   <executions>
     <execution>
       <id>default-compile</id>
       <phase>compile</phase>
       <goals>
         <goal>compile</goal>
       </goals>
     </execution>
     <execution>
       <id>default-testCompile</id>
       <phase>test-compile</phase>
       <goals>
         <goal>testCompile</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
  ...

You can have more information about it in the introduction of the Maven lifeycle in the Maven documentation.

Nevertheless, you can declare these plugins when you want to configure them with other values as default values (for example, you did it when you declared the maven-compiler plugin in your pom.xml to adjust the JDK version to use) or when you want to add some plugin executions not used by default in the Maven lifecycle.

You can't wrap that text as it's unbroken without any spaces. You need a JavaScript or server side solution which splits the string after a few characters.

EDIT

You need to add this property in CSS.

word-wrap: break-word;

DisplayFor is also useful for templating. You could write a template for your Model, and do something like this:

@Html.DisplayFor(m => m)

Similar to @Html.EditorFor(m => m). It's useful for the DRY principal so that you don't have to write the same display logic over and over for the same Model.

Take a look at this blog on MVC2 templates. It's still very applicable to MVC3:

http://www.dalsoft.co.uk/blog/index.php/2010/04/26/mvc-2-templates/

It's also useful if your Model has a Data annotation. For instance, if the property on the model is decorated with the EmailAddress data annotation, DisplayFor will render it as a mailto: link.

A slightly simpler method:

>>> t = ((1, 'a'),(2, 'b'))
>>> dict(map(reversed, t))
{'a': 1, 'b': 2}

because you have set index is 0 it shows always 1st value from combobox as input.

Try this :

With Me.ComboBox1
    .DropDownStyle = ComboBoxStyle.DropDown
    .Text = " "
End With

LEFT(colName, 1) will also do this, also. It's equivalent to SUBSTRING(colName, 1, 1).

I like LEFT, since I find it a bit cleaner, but really, there's no difference either way.

Given what you said in a comment:

my id coloumn is auto increment i have to get the id and convert it to another base.So i need to get the next id before insert cause converted code will be inserted too.

There is a way to do what you're asking, which is to ask the table what the next inserted row's id will be before you actually insert:

SHOW TABLE STATUS WHERE name = "myTable"

there will be a field in that result set called "Auto_increment" which tells you the next auto increment value.

This appears to be a more general SWING/AWT/JDK problem that just the JBOSS installer:

The accepted answer below solved the issue for me :

Unable to run java gui programs with ubuntu

("sudo apt-get install openjdk-6-jdk")

Most of the times it should not be used as the primary key for a table because it really hit the performance of the database. useful links regarding GUID impact on performance and as a primary key.

Do you mean to property files located in src/main/resources? Then you should exclude them using the maven-resource-plugin. See the following page for details:

http://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html

getUserRootFolder() {
  return process.env.HOME || process.env.HOMEPATH || process.env.USERPROFILE;
}

The cause of your problems is that you are trying to do a cross-domain call and it fails.

If you're doing localhost development you can make cross-domain calls - I do it all the time.

For Firefox, you have to enable it in your config settings

signed.applets.codebase_principal_support = true

Then add something like this to your XHR open code:

  if (isLocalHost()){
    if (typeof(netscape) != 'undefined' && typeof(netscape.security) != 'undefined'){
      netscape.security.PrivilegeManager.enablePrivilege('UniversalBrowserRead');
    }
  }

For IE, if I remember right, all you have to do is enable the browser's Security setting under "Miscellaneous → Access data sources across domains" to get it to work with ActiveX XHRs.

IE8 and above also added cross-domain capabilities to the native XmlHttpRequest objects, but I haven't played with those yet.

If you want to disable the highlight for a single list view item, but keep the cell enabled, set the background color for that cell to disable the highlighting.

For instance, in your cell layout, set android:background="@color/white"

I had the same problem in docker and these steps worked for me:

apt update

then:

apt install libsm6 libxext6 libxrender-dev

LDF holds the transaction log. If you set your backups correctly - it will be small. It it grows - you have a very common problem of setting database recovery mode to FULL and then forgetting to backup the transaction log (LDF file). Let me explain how to fix it.

1. If your business can afford to lose a little data between backups, just set the database recovery mode to SIMPLE, then forget about LDF - it will be small. This is the recommended solution for most of the cases.
2. If you have to be able to restore to the exact point in time - use FULL recovery mode. In this case you have to take regular Transaction Log backups. The simplest way to do it is to use a tool like SqlBackupAndFTP (disclosure - I am a developer). The log file will be truncated at this time and would not grow beyond certain limits.

Some would suggest to use SHRINKFILE to trim you log. Note that this is OK only as an exception. If you do it regularly, it defeats the purpose of FULL recovery model: first you go into trouble of saving every single change in the log, then you just dump it. Set recovery mode to SIMPLE instead.

Why does it implement its methods? How can it implement its methods when an interface can't contain method body? How can it implement the methods when it extends the other interface and not implement it? What is the purpose of an interface implementing another interface?

Interface does not implement the methods of another interface but just extends them. One example where the interface extension is needed is: consider that you have a vehicle interface with two methods moveForward and moveBack but also you need to incorporate the Aircraft which is a vehicle but with some addition methods like moveUp, moveDown so in the end you have:

public interface IVehicle {
  bool moveForward(int x);
  bool moveBack(int x);
};

and airplane:

public interface IAirplane extends IVehicle {
  bool moveDown(int x);
  bool moveUp(int x);
};

Try below code :

Assign the path of the folder to variable FolderPath before running the below code.

Sub sample()

    Dim FolderPath As String, path As String, count As Integer
    FolderPath = "C:\Documents and Settings\Santosh\Desktop"

    path = FolderPath & "\*.xls"

    Filename = Dir(path)

    Do While Filename <> ""
       count = count + 1
        Filename = Dir()
    Loop

    Range("Q8").Value = count
    'MsgBox count & " : files found in folder"
End Sub

I had the same problem. Coudn't resolve google.com. There was a bug somewhere in php fpm, which i am using. Restarting php-fpm solved it for me.

You need to execute all the different-user commands as their own script. If it's just one, or a few commands, then inline should work. If it's lots of commands then it's probably best to move them to their own file.

su -c "cd /home/$USERNAME/$PROJECT ; svn update" -m "$USERNAME" 

try

 cat ~/.mysql_history

this will show you all mysql commands ran on the system

Please store your JSON file with the .js extension and make sure that your JSON should be in same directory.

You shouldn't need a $watch. Just bind to resize event on window:

DEMO

'use strict';

var app = angular.module('plunker', []);

app.directive('myDirective', ['$window', function ($window) {

     return {
        link: link,
        restrict: 'E',
        template: '<div>window size: {{width}}px</div>'
     };

     function link(scope, element, attrs){

       scope.width = $window.innerWidth;

       angular.element($window).bind('resize', function(){

         scope.width = $window.innerWidth;

         // manuall $digest required as resize event
         // is outside of angular
         scope.$digest();
       });

     }

 }]);

I believe some people may come to this question wanting to know how to rollback committed changes they've made in their master - ie throw everything away and go back to origin/master, in which case, do this:

git reset --hard origin/master

https://superuser.com/questions/273172/how-to-reset-master-to-origin-master

You just do an opposite comparison. if Col2 <= 1. This will return a boolean Series with False values for those greater than 1 and True values for the other. If you convert it to an int64 dtype, True becomes 1 and False become 0,

df['Col3'] = (df['Col2'] <= 1).astype(int)

If you want a more general solution, where you can assign any number to Col3 depending on the value of Col2 you should do something like:

df['Col3'] = df['Col2'].map(lambda x: 42 if x > 1 else 55)

Or:

df['Col3'] = 0
condition = df['Col2'] > 1
df.loc[condition, 'Col3'] = 42
df.loc[~condition, 'Col3'] = 55

Django does not support free group by queries. I learned it in the very bad way. ORM is not designed to support stuff like what you want to do, without using custom SQL. You are limited to:

• RAW sql (i.e. MyModel.objects.raw())
• cr.execute sentences (and a hand-made parsing of the result).
• .annotate() (the group by sentences are performed in the child model for .annotate(), in examples like aggregating lines_count=Count('lines'))).

Over a queryset qs you can call qs.query.group_by = ['field1', 'field2', ...] but it is risky if you don't know what query are you editing and have no guarantee that it will work and not break internals of the QuerySet object. Besides, it is an internal (undocumented) API you should not access directly without risking the code not being anymore compatible with future Django versions.

A rather simplistic approach that seems to be working...

String getPublicIPv4() throws UnknownHostException, SocketException{
    Enumeration<NetworkInterface> e = NetworkInterface.getNetworkInterfaces();
    String ipToReturn = null;
    while(e.hasMoreElements())
    {
        NetworkInterface n = (NetworkInterface) e.nextElement();
        Enumeration<InetAddress> ee = n.getInetAddresses();
        while (ee.hasMoreElements())
        {
            InetAddress i = (InetAddress) ee.nextElement();
            String currentAddress = i.getHostAddress();
            logger.trace("IP address "+currentAddress+ " found");
            if(!i.isSiteLocalAddress()&&!i.isLoopbackAddress() && validate(currentAddress)){
                ipToReturn = currentAddress;    
            }else{
                System.out.println("Address not validated as public IPv4");
            }

        }
    }

    return ipToReturn;
}

private static final Pattern IPv4RegexPattern = Pattern.compile(
        "^(([01]?\\d\\d?|2[0-4]\\d|25[0-5])\\.){3}([01]?\\d\\d?|2[0-4]\\d|25[0-5])$");

public static boolean validate(final String ip) {
    return IPv4RegexPattern.matcher(ip).matches();
}

Ultimately you want to review the datetime documentation and become familiar with the formatting variables, but here are some examples to get you started:

import datetime

print('Timestamp: {:%Y-%m-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Timestamp: {:%Y-%b-%d %H:%M:%S}'.format(datetime.datetime.now()))
print('Date now: %s' % datetime.datetime.now())
print('Date today: %s' % datetime.date.today())

today = datetime.date.today()
print("Today's date is {:%b, %d %Y}".format(today))

schedule = '{:%b, %d %Y}'.format(today) + ' - 6 PM to 10 PM Pacific'
schedule2 = '{:%B, %d %Y}'.format(today) + ' - 1 PM to 6 PM Central'
print('Maintenance: %s' % schedule)
print('Maintenance: %s' % schedule2)

The output:

Timestamp: 2014-10-18 21:31:12

Timestamp: 2014-Oct-18 21:31:12

Date now: 2014-10-18 21:31:12.318340

Date today: 2014-10-18

Today's date is Oct, 18 2014

Maintenance: Oct, 18 2014 - 6 PM to 10 PM Pacific

Maintenance: October, 18 2014 - 1 PM to 6 PM Central

To not have to worry whether you are running your scripts on Windows, Mac or Linux install the cross-env package. Then you can use your scripts easily, like so:

"scripts": {
    "start-dev": "cross-env NODE_ENV=development nodemon --exec babel-node -- src/index.js",
    "start-prod": "cross-env NODE_ENV=production nodemon --exec babel-node -- src/index.js"
}

Massive props to the developers of this package.

npm install --save-dev cross-env

You can use $(!!) to recompute (not re-use) the output of the last command.

The !! on its own executes the last command.

$ echo pierre
pierre
$ echo my name is $(!!)
echo my name is $(echo pierre)
my name is pierre

echo "Enter no of terms"
read count
for i in $(seq 1 $count)
do
  t=` expr $i - 1 `
  for j in $(seq $t -1 0)
  do
    echo -n " "
  done
  j=` expr $count + 1 `
  x=` expr $j - $i `
  for k in $(seq 1 $x)
  do
    echo -n "* "
  done
  echo ""
done

As I have found and wrote in another topic - this applies to angular < 7 (not sure how it is in 7+)

Just for the future

we need to observe that [(ngModel)]="hero.name" is just a short-cut that can be de-sugared to: [ngModel]="hero.name" (ngModelChange)="hero.name = $event".

So if we de-sugar code we would end up with:

<select (ngModelChange)="onModelChange()" [ngModel]="hero.name" (ngModelChange)="hero.name = $event">

or

<[ngModel]="hero.name" (ngModelChange)="hero.name = $event" select (ngModelChange)="onModelChange()">

If you inspect the above code you will notice that we end up with 2 ngModelChange events and those need to be executed in some order.

Summing up: If you place ngModelChange before ngModel, you get the $event as the new value, but your model object still holds previous value. If you place it after ngModel, the model will already have the new value.

There are lot of factors , first see whether server returns the result, then check between server and client.

rectify them from server side first,then check the writing condition between server and client !

server side rectify the time outs between the datalayer and server from client side rectify the time out and number of available connections !

Java 8 user can do that: list.removeIf(...)

    List<String> list = new ArrayList<>(Arrays.asList("a", "b", "c"));
    list.removeIf(e -> (someCondition));

It will remove elements in the list, for which someCondition is satisfied

All API

if use all API just create the theme in style

style.xml

<resources>

    //...

    <style name="progressBarBlue" parent="@style/Theme.AppCompat">
        <item name="colorAccent">@color/blue</item>
    </style>

</resources>

and use in progress

<ProgressBar
    ...
    android:theme="@style/progressBarBlue" />

API level 21 and higher

if used in API level 21 and higher just use this code:

<ProgressBar
   //...
   android:indeterminate="true"
   android:indeterminateTintMode="src_atop"
   android:indeterminateTint="@color/secondary"/>

One can issue the SQL*Plus command SET TIMING ON to get wall-clock times, but one can't take, for example, fetch time out of that trivially.

The AUTOTRACE setting, when used as SET AUTOTRACE TRACEONLY will suppress output, but still perform all of the work to satisfy the query and send the results back to SQL*Plus, which will suppress it.

Lastly, one can trace the SQL*Plus session, and manually calculate the time spent waiting on events which are client waits, such as "SQL*Net message to client", "SQL*Net message from client".

I had come across this issue for a complex model with several nested objects. A good example of what I was looking at doing would be this: Lets say you have a polaroid of yourself. And that picture is then put into a trunk of a car. The car is inside of a large crate. The crate is in the hold of a large ship with many other crates. I had to search the hold, look in the crates, check the trunk, and then look for an existing picture of me.

I could not find any good solutions online to use, and using .filter() only works on arrays. Most solutions suggested just checking to see if model["yourpicture"] existed. This was very undesirable because, from the example, that would only search the hold of the ship and I needed a way to get them from farther down the rabbit hole.

This is the recursive solution I made. In comments, I confirmed from T.J. Crowder that a recursive version would be required. I thought I would share it in case anyone came across a similar complex situation.

function ContainsKeyValue( obj, key, value ){
    if( obj[key] === value ) return true;
    for( all in obj )
    {
        if( obj[all] != null && obj[all][key] === value ){
            return true;
        }
        if( typeof obj[all] == "object" && obj[all]!= null ){
            var found = ContainsKeyValue( obj[all], key, value );
            if( found == true ) return true;
        }
    }
    return false;
}

This will start from a given object inside of the graph, and recurse down any objects found. I use it like this:

var liveData = [];
for( var items in viewmodel.Crates )
{
    if( ContainsKeyValue( viewmodel.Crates[items], "PictureId", 6 ) === true )
    {
        liveData.push( viewmodel.Crates[items] );
    }
}

Which will produce an array of the Crates which contained my picture.

As other answers have stated, there really just isn't a way that's any good. Base64 can be decoded. Bytecode can be decompiled. Python was initially just interpreted, and most interpreted languages try to speed up machine interpretation more than make it difficult for human interpretation.

Python was made to be readable and shareable, not obfuscated. The language decisions about how code has to be formatted were to promote readability across different authors.

Obfuscating python code just doesn't really mesh with the language. Re-evaluate your reasons for obfuscating the code.

I fixed this by setting the Enabled property to false.

I ran into this problem because the Android-Maven-plugin in Eclipse was apparently not recognizing transitive references and references referenced twice from a couple of projects (including an Android library project), and including them more than once. I had to use hocus-pocus to get everything included only once, even though Maven is supposed to take care of all this.

For example, I had a core library globalmentor-core, that was also used by globalmentor-google and globalmentor-android (the latter of which is an Android library). In the globalmentor-android pom.xml I had to mark the dependency as "provided" as well as excluded from other libraries in which it was transitively included:

    <dependency>
        <groupId>com.globalmentor</groupId>
        <artifactId>globalmentor-core</artifactId>
        <version>1.0-SNAPSHOT</version>
        <!-- android-maven-plugin can't seem to automatically keep this from being
             included twice; it must therefore be included manually (either explicitly
             or transitively) in dependent projects -->
        <scope>provided</scope>
    </dependency>

Then in the final application pom.xml I had to use the right trickery to allow only one inclusion path---as well as not explicitly including the core library:

    <!-- android-maven-plugin can't seem to automatically keep this from being
        included twice -->
    <!-- <dependency> -->
    <!-- <groupId>com.globalmentor</groupId> -->
    <!-- <artifactId>globalmentor-core</artifactId> -->
    <!-- <version>1.0-SNAPSHOT</version> -->
    <!-- </dependency> -->

    <dependency>
        <groupId>com.globalmentor</groupId>
        <artifactId>globalmentor-google</artifactId>
        <version>1.0-SNAPSHOT</version>
        <exclusions>
            <!-- android-maven-plugin can't seem to automatically keep this from
                being included twice -->
            <exclusion>
                <groupId>com.globalmentor</groupId>
                <artifactId>globalmentor-core</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

    <dependency>
        <groupId>com.globalmentor</groupId>
        <artifactId>globalmentor-android</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

The values you provided are UTF-8 values. When set, the array of:

declare -a ARR=(0xA7 0x9B 0x46 0x8D 0x1E 0x52 0xA7 0x9B 0x7B 0x31 0xD2)

Will be parsed to print the plaintext characters of each value.

for ((n=0; n < ${#ARR[*]}; n++)); do echo -e "\u${ARR[$n]//0x/}"; done

And the output will yield a few printable characters and some non-printable characters as shown here:

For converting hex values to plaintext using the echo command:

echo -e "\x<hex value here>"

And for converting UTF-8 values to plaintext using the echo command:

echo -e "\u<UTF-8 value here>"

And then for converting octal to plaintext using the echo command:

echo -e "\0<octal value here>"

When you have encoding values you aren't familiar with, take the time to check out the ranges in the common encoding schemes to determine what encoding a value belongs to. Then conversion from there is a snap.

Most certainly, export JAVA_HOME=/usr/bin/java is the culprit. This env var should point to the JDK or JRE installation directory. Googling shows that the best option for MacOS X seems to be export JAVA_HOME=/Library/Java/Home.

This question has been already answered in Unicode characters in Windows command line - how?

You missed one step -> you need to use Lucida console fonts in addition to executing chcp 65001 from cmd console.

An alternative strict solution using the standard library is to perform the following:

1) Create a strict SimpleDateFormat using your pattern

2) Attempt to parse the user entered value using the format object

3) If successful, reformat the Date resulting from (2) using the same date format (from (1))

4) Compare the reformatted date against the original, user-entered value. If they're equal then the value entered strictly matches your pattern.

This way, you don't need to create complex regular expressions - in my case I needed to support all of SimpleDateFormat's pattern syntax, rather than be limited to certain types like just days, months and years.

I have the same issue with the ".index()" method on lists. I have no issue with the fact that it throws an exception but I strongly disagree with the fact that it's a non-descriptive ValueError. I could understand if it would've been an IndexError, though.

I can see why returning "-1" would be an issue too because it's a valid index in Python. But realistically, I never expect a ".index()" method to return a negative number.

Here goes a one liner (ok, it's a rather long line ...), goes through the list exactly once and returns "None" if the item isn't found. It would be trivial to rewrite it to return -1, should you so desire.

indexOf = lambda list, thing: \
            reduce(lambda acc, (idx, elem): \
                   idx if (acc is None) and elem == thing else acc, list, None)

How to use:

>>> indexOf([1,2,3], 4)
>>>
>>> indexOf([1,2,3], 1)
0
>>>

Sorry to pile on to an old item. I found partial answers to my questions here but had to do some work so I wanted to share my results for the next person.

I ended up using the same approach as the other contributors, but with a few tweaks to fix the following

1. Long text was covering the arrows in the other solutions
2. The image being used was a somewhat old and ugly up/down combo arrow.

The below will give you a working solution with the above issues fixed. Note: I used a white arrow for my use case, you may need to change the color of the arrow for yours.

This should work :

The instructions says that you add a separate .htaccess containing the lines above to the wp-admin folder - and leave the main .htaccess, in the root, alone.

if that don't help , you can try this:

copy the .htaccess file as is from the wp-admin and placed it in the root folder and bingo! It should work ! if you face new error after this let us know.

for reference you can look here as well:

Another possibility is too many threads. We just ran into this error message when running a test harness against an app that uses a thread pool. We used

watch -n 5 -d "ps -eL <java_pid> | wc -l"

to watch the ongoing count of Linux native threads running within the given Java process ID. After this hit about 1,000 (for us--YMMV), we started getting the error message you mention.

To me, it seems as if your actual intention is to put different words on different lines. But let me answer your first question:

JLabel lab=new JLabel("text");
lab.setHorizontalAlignment(SwingConstants.LEFT);     

And if you have an image:

JLabel lab=new Jlabel("text");
lab.setIcon(new ImageIcon("path//img.png"));
lab.setHorizontalTextPosition(SwingConstants.LEFT);

But, I believe you want to make the label such that there are only 2 words on 1 line.

In that case try this:

String urText="<html>You can<br>use basic HTML<br>in Swing<br> components," 
   +"Hope<br> I helped!";
JLabel lac=new JLabel(urText);
lac.setAlignmentX(Component.RIGHT_ALIGNMENT);

This same problem just started occurring for me and I was able to "fix" it by updating the vcvars32.bat file located in the C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\ folder (by default). Add the following after the first line:

@SET VSINSTALLDIR=c:\Program Files\Microsoft Visual Studio 10.0\
@SET VCINSTALLDIR=c:\Program Files\Microsoft Visual Studio 10.0\VC\
@SET FrameworkDir32=c:\Windows\Microsoft.NET\Framework\
@SET FrameworkVersion32=v4.0.30319
@SET Framework35Version=v3.5

And then comment out the following lines:

:: @call :GetVSCommonToolsDir
:: @if "%VS100COMNTOOLS%"=="" goto error_no_VS100COMNTOOLSDIR
:: @call "%VS100COMNTOOLS%VCVarsQueryRegistry.bat" 32bit No64bit

Found this here. Note that I say fix in quotes because I haven't checked to make sure that all the appropriate variables are set properly; that said, at a cursory glance it does appear to be valid.

Note that you'll have to edit the vcvars32.bat file in an elevated text editor (ie, Run as Admin) to be able to save the file in Vista and Windows 7.

If you could reload this, you might be able to use dtypes argument.

One-liner for a quick-and-easy JSON representation:

    echo json_encode($data, JSON_PRETTY_PRINT);

If using composer for the project already, require symfony/yaml and:

    echo Yaml::dump($data);

Did you just try

$('#datebox li a').on('click', function(){
    //$('#datebox').val($(this).text());
    alert($(this).text());
});

It works for me :)

You have to do binding in a directive. Look at this:

angular.module('ng', []).
directive('sliderRange', function($parse, $timeout){
    return {
        restrict: 'A',
        replace: true,
        transclude: false,
        compile: function(element, attrs) {            
            var html = '<div class="slider-range"></div>';
            var slider = $(html);
            element.replaceWith(slider);
            var getterLeft = $parse(attrs.ngModelLeft), setterLeft = getterLeft.assign;
            var getterRight = $parse(attrs.ngModelRight), setterRight = getterRight.assign;

            return function (scope, slider, attrs, controller) {
                var vsLeft = getterLeft(scope), vsRight = getterRight(scope), f = vsLeft || 0, t = vsRight || 10;                        

                var processChange = function() {
                    var vs = slider.slider("values"), f = vs[0], t = vs[1];                                        
                    setterLeft(scope, f);
                    setterRight(scope, t);                    
                }                 
                slider.slider({
                    range: true,
                    min: 0,
                    max: 10,
                    step: 1,
                    change: function() { setTimeout(function () { scope.$apply(processChange); }, 1) }
                }).slider("values", [f, t]);                    
            };            
        }
    };
});

This shows you an example of a slider range, done with jQuery UI. Example usage:

<div slider-range ng-model-left="question.properties.range_from" ng-model-right="question.properties.range_to"></div>

Note from 2017: File::Slurp is not recommended due to design mistakes and unmaintained errors. Use File::Slurper or Path::Tiny instead.

extending on your answer

use File::Slurp ();
my $value = File::Slurp::slurp($filename);
$value =~ s/\R*//g;

File::Slurp abstracts away the File IO stuff and just returns a string for you.

NOTE

1. Important to note the addition of /g , without it, given a multi-line string, it will only replace the first offending character.

2. Also, the removal of $, which is redundant for this purpose, as we want to strip all line breaks, not just line-breaks before whatever is meant by $ on this OS.

3. In a multi-line string, $ matches the end of the string and that would be problematic ).

4. Point 3 means that point 2 is made with the assumption that you'd also want to use /m otherwise '$' would be basically meaningless for anything practical in a string with >1 lines, or, doing single line processing, an OS which actually understands $ and manages to find the \R* that proceed the $

Examples

while( my $line = <$foo> ){
      $line =~ $regex;
}

Given the above notation, an OS which does not understand whatever your files '\n' or '\r' delimiters, in the default scenario with the OS's default delimiter set for $/ will result in reading your whole file as one contiguous string ( unless your string has the $OS's delimiters in it, where it will delimit by that )

So in this case all of these regex are useless:

• /\R*$// : Will only erase the last sequence of \R in the file
• /\R*// : Will only erase the first sequence of \R in the file

• /\012?\015?// : When will only erase the first 012\015 , \012 , or \015 sequence, \015\012 will result in either \012 or \015 being emitted.

• /\R*$// : If there happens to be no byte sequences of '\015$OSDELIMITER' in the file, then then NO linebreaks will be removed except for the OS's own ones.

It would appear nobody gets what I'm talking about, so here is example code, that is tested to NOT remove line feeds. Run it, you'll see that it leaves the linefeeds in.

#!/usr/bin/perl

Note there are certain combinations that of course work, but they are likely the ones you yourself naívely tested.

Note that in this output, all results must be of the form >|$string|<>|$string|< with NO LINE FEEDS to be considered valid output.

and $string is of the general form {0}$data{1}$delimiter{2} where in all output sources, there should be either :

1. Nothing between {1} and {2}
2. only |<>| between {1} and {2}

I think your choices are

• Use a map implementation built for this, like the BiMap from google collections. Note that the google collections BiMap requires uniqueless of values, as well as keys, but it provides high performance in both directions performance
• Manually maintain two maps - one for key -> value, and another map for value -> key
• Iterate through the entrySet() and to find the keys which match the value. This is the slowest method, since it requires iterating through the entire collection, while the other two methods don't require that.

for jQuery we can use below:

by input name:

$('input[name="textboxname"]').val('some value');

by input class:

$('input[type=text].textboxclass').val('some value');

by input id:

$('#textboxid').val('some value');

If you are able to wrap your XML in a root element - say then the following is your solution:

DECLARE @PersonsXml XML = '<persons><person><firstName>Jon</firstName><lastName>Johnson</lastName></person>
<person><firstName>Kathy</firstName><lastName>Carter</lastName></person>
<person><firstName>Bob</firstName><lastName>Burns</lastName></person></persons>'

SELECT  b.value('(./firstName/text())[1]','nvarchar(max)') as FirstName, b.value('(./lastName/text())[1]','nvarchar(max)') as LastName
FROM @PersonsXml.nodes('/persons/person') AS a(b)

You're currently writing the binary data in the string-object to your file. This binary data will probably only consist of a pointer to the actual data, and an integer representing the length of the string.

If you want to write to a text file, the best way to do this would probably be with an ofstream, an "out-file-stream". It behaves exactly like std::cout, but the output is written to a file.

The following example reads one string from stdin, and then writes this string to the file output.txt.

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

int main()
{
    std::string input;
    std::cin >> input;
    std::ofstream out("output.txt");
    out << input;
    out.close();
    return 0;
}

Note that out.close() isn't strictly neccessary here: the deconstructor of ofstream can handle this for us as soon as out goes out of scope.

For more information, see the C++-reference: http://cplusplus.com/reference/fstream/ofstream/ofstream/

Now if you need to write to a file in binary form, you should do this using the actual data in the string. The easiest way to acquire this data would be using string::c_str(). So you could use:

write.write( studentPassword.c_str(), sizeof(char)*studentPassword.size() );

Neither main() or void main() are standard C. The former is allowed as it has an implicit int return value, making it the same as int main(). The purpose of main's return value is to return an exit status to the operating system.

In standard C, the only valid signatures for main are:

int main(void)

and

int main(int argc, char **argv)

The form you're using: int main() is an old style declaration that indicates main takes an unspecified number of arguments. Don't use it - choose one of those above.

define this "decoratorize function" to generate customized decorator function:

def decoratorize(FUN, **kw):
    def foo(*args, **kws):
        return FUN(*args, **kws, **kw)
    return foo

use it this way:

    @decoratorize(FUN, arg1 = , arg2 = , ...)
    def bar(...):
        ...

Edit: OP (or an editor) silently changed some of the single quotes in the original question to double quotes at some point after I provided this answer.

Your code will result in compiler errors. Your first code fragment:

char buf[10] ; buf = ''

is doubly illegal. First, in C, there is no such thing as an empty char. You can use double quotes to designate an empty string, as with:

char* buf = ""; 

That will give you a pointer to a NUL string, i.e., a single-character string with only the NUL character in it. But you cannot use single quotes with nothing inside them--that is undefined. If you need to designate the NUL character, you have to specify it:

char buf = '\0';

The backslash is necessary to disambiguate from character '0'.

char buf = 0;

accomplishes the same thing, but the former is a tad less ambiguous to read, I think.

Secondly, you cannot initialize arrays after they have been defined.

char buf[10];

declares and defines the array. The array identifier buf is now an address in memory, and you cannot change where buf points through assignment. So

buf =     // anything on RHS

is illegal. Your second and third code fragments are illegal for this reason.

To initialize an array, you have to do it at the time of definition:

char buf [10] = ' ';

will give you a 10-character array with the first char being the space '\040' and the rest being NUL, i.e., '\0'. When an array is declared and defined with an initializer, the array elements (if any) past the ones with specified initial values are automatically padded with 0. There will not be any "random content".

If you declare and define the array but don't initialize it, as in the following:

char buf [10];

you will have random content in all the elements.

One common case for explicitly flushing is when you create a new persistent entity and you want it to have an artificial primary key generated and assigned to it, so that you can use it later on in the same transaction. In that case calling flush would result in your entity being given an id.

Another case is if there are a lot of things in the 1st-level cache and you'd like to clear it out periodically (in order to reduce the amount of memory used by the cache) but you still want to commit the whole thing together. This is the case that Aleksei's answer covers.

Bootstrap's CSS for the .container class looks like that:

.container {
    padding-right: 15px;
    padding-left: 15px;
    margin-right: auto;
    margin-left: auto;
}
@media (min-width: 768px) {
    .container {
        width: 750px;
    }
}
@media (min-width: 992px) {
    .container {
        width: 970px;
    }
}
@media (min-width: 1200px) {
    .container {
        width: 1170px;
    }
}

So this means we can safely rely on jQuery('.container').css('width') to detect breakpoints without the drawbacks of relying on jQuery(window).width().

We can write a function like this:

function detectBreakpoint() {
    // Let's ensure we have at least 1 container in our pages.
    if (jQuery('.container').length == 0) {
        jQuery('body').append('<div class="container"></div>');
    }

    var cssWidth = jQuery('.container').css('width');

    if (cssWidth === '1170px') return 'lg';
    else if (cssWidth === '970px') return 'md';
    else if (cssWidth === '750px') return 'sm';

    return 'xs';
}

And then test it like

jQuery(document).ready(function() {
    jQuery(window).resize(function() {
        jQuery('p').html('current breakpoint is: ' + detectBreakpoint());
    });

    detectBreakpoint();
});

As others have noted, most likely you don't have .html set up to handle php code.

Having said that, if all you're doing is using index.html to include index.php, your question should probably be 'how do I use index.php as index document?

In which case, for Apache (httpd.conf), search for DirectoryIndex and replace the line with this (will only work if you have dir_module enabled, but that's default on most installs):

DirectoryIndex index.php

If you use other directory indexes, list them in order of preference i.e.

DirectoryIndex index.php index.phtml index.html index.htm

In AquaMacs CMD + and CMD - adjust the font size for the current buffer.

If you wish to stay away from regular expressions, the simplest way I can think of is:

string input = "User name (sales)";
string output = input.Split('(', ')')[1];

In Java 11, you have repeat:

String s = " ";
s = s.repeat(1);

(Although at the time of writing still subject to change)

This may be overkill for what you're looking for, but there is an npm package called marky that you can use to do this. It gives you a couple of extra features beyond just starting and stopping a timer. You just need to install it via npm and then import the dependency anywhere you'd like to use it. Here is a link to the npm package: https://www.npmjs.com/package/marky

An example of use after installing via npm would be as follows:

import * as _M from 'marky';

@Component({
 selector: 'app-test',
 templateUrl: './test.component.html',
 styleUrls: ['./test.component.scss']
})

export class TestComponent implements OnInit {
 Marky = _M;
}

constructor() {}

ngOnInit() {}

startTimer(key: string) {
 this.Marky.mark(key);
}

stopTimer(key: string) {
 this.Marky.stop(key);
}

key is simply a string which you are establishing to identify that particular measurement of time. You can have multiple measures which you can go back and reference your timer stats using the keys you create.

When I disabled the stack smashing protector no errors were detected, which should have happened when I used "./a.out wepassssssssssssssssss"

So to answer your question above, the message "** stack smashing detected : xxx" was displayed because your stack smashing protector was active and found that there is stack overflow in your program.

Just find out where that occurs, and fix it.

I wanted to add one more point is, if you are storing a really large number like 902054990011312 then one can easily see the difference of INT(20) and BIGINT(20). It is advisable to store in BIGINT.

Here is the solution for c# MVC:

1. First : Create a custom attribute and override method like this:

   public class CultureAttribute : ActionFilterAttribute
   {
       public override void OnActionExecuting(ActionExecutingContext filterContext)
       {
           // Retreive culture from GET
           string currentCulture = filterContext.HttpContext.Request.QueryString["culture"];
   
           // Also, you can retreive culture from Cookie like this :
           //string currentCulture = filterContext.HttpContext.Request.Cookies["cookie"].Value;
   
           // Set culture
           Thread.CurrentThread.CurrentCulture = new CultureInfo(currentCulture);
           Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture(currentCulture);
       }
   }
   

2. Second : In App_Start, find FilterConfig.cs, add this attribute. (this works for WHOLE application)

   public class FilterConfig
   {
       public static void RegisterGlobalFilters(GlobalFilterCollection filters)
       {
           // Add custom attribute here
           filters.Add(new CultureAttribute());
       }
   }    
   

That's it !

If you want to define culture for each controller/action in stead of whole application, you can use this attribute like this:

[Culture]
public class StudentsController : Controller
{
}

Or:

[Culture]
public ActionResult Index()
{
    return View();
}

sleep()causes the thread to definitely stop executing for a given amount of time; if no other thread or process needs to be run, the CPU will be idle (and probably enter a power saving mode). yield()basically means that the thread is not doing anything particularly important and if any other threads or processes need to be run, they should. Otherwise, the current thread will continue to run.

I have had a similar problem, turns out we don't need hooks to do these, we can make an conditional render and it will still work fine.

<Button
    type="submit"
    disabled={
        name === "" || email === "" || password === "" ? true : false
    }
    fullWidth
    variant="contained"
    color="primary"
    className={classes.submit}>
    SignUP
</Button>

If you just want a really simple way to do this.. Heres a script I have used in the past

select 'drop table '||table_name||' cascade constraints;' from user_tables;

This will print out a series of drop commands for all tables in the schema. Spool the result of this query and execute it.

Source: https://forums.oracle.com/forums/thread.jspa?threadID=614090

Likewise if you want to clear more than tables you can edit the following to suit your needs

select 'drop '||object_type||' '|| object_name || ';' from user_objects where object_type in ('VIEW','PACKAGE','SEQUENCE', 'PROCEDURE', 'FUNCTION', 'INDEX')

I am using angular 4 and faced the same issue apply, all possible solution but finally, this solve my problem

export class AppRoutingModule {
constructor(private router: Router) {
    this.router.errorHandler = (error: any) => {
        this.router.navigate(['404']); // or redirect to default route
    }
  }
}

Hope this will help you.

For embeding youtube video into your angularjs page, you can simply use following filter for your video

app.filter('scrurl', function($sce) {_x000D_
    return function(text) {_x000D_
        text = text.replace("watch?v=", "embed/");_x000D_
        return $sce.trustAsResourceUrl(text);_x000D_
    };_x000D_
});

<iframe class="ytplayer" type="text/html" width="100%" height="360" src="{{youtube_url | scrurl}}" frameborder="0"></iframe>

If you do not want to mess with what should be the primary key, I recommend:

1. Incorporate ROW_NUMBER into your selection
2. Set it as primary key
3. Set all other columns/members as non-primary in the model

There is no need for subplots, and pyplot can display PIL images, so this can be simplified further:

import matplotlib.pyplot as plt
from matplotlib.patches import Rectangle
from PIL import Image

im = Image.open('stinkbug.png')

# Display the image
plt.imshow(im)

# Get the current reference
ax = plt.gca()

# Create a Rectangle patch
rect = Rectangle((50,100),40,30,linewidth=1,edgecolor='r',facecolor='none')

# Add the patch to the Axes
ax.add_patch(rect)

Or, the short version:

import matplotlib.pyplot as plt
from matplotlib.patches import Rectangle
from PIL import Image

# Display the image
plt.imshow(Image.open('stinkbug.png'))

# Add the patch to the Axes
plt.gca().add_patch(Rectangle((50,100),40,30,linewidth=1,edgecolor='r',facecolor='none'))

As already mentioned you can use Fine Code Coverage that visualize coverlet output. If you create a xunit test project (dotnet new xunit) you'll find coverlet reference already present in csproj file because Coverlet is the default coverage tool for every .NET Core and >= .NET 5 applications.

Microsoft has an example using ReportGenerator that converts coverage reports generated by coverlet, OpenCover, dotCover, Visual Studio, NCover, Cobertura, JaCoCo, Clover, gcov or lcov into human readable reports in various formats.

Example report:

While the article focuses on C# and xUnit as the test framework, both MSTest and NUnit would also work.

Guide:

https://docs.microsoft.com/en-us/dotnet/core/testing/unit-testing-code-coverage?tabs=windows#generate-reports

If you want code coverage in .xml files you can run any of these commands:

dotnet test --collect:"XPlat Code Coverage"

dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura

I haven't tested your code, just tried to help you understand how it operates in comment;

The simplest example of a recursive CTE I can think of to illustrate its operation is;

;WITH Numbers AS
(
    SELECT n = 1
    UNION ALL
    SELECT n + 1
    FROM Numbers
    WHERE n+1 <= 10
)
SELECT n
FROM Numbers

Q 1) how value of N is getting incremented. if value is assign to N every time then N value can be incremented but only first time N value was initialize.

A1: In this case, N is not a variable. N is an alias. It is the equivalent of SELECT 1 AS N. It is a syntax of personal preference. There are 2 main methods of aliasing columns in a CTE in T-SQL. I've included the analog of a simple CTE in Excel to try and illustrate in a more familiar way what is happening.

--  Outside
;WITH CTE (MyColName) AS
(
    SELECT 1
)
-- Inside
;WITH CTE AS
(
    SELECT 1 AS MyColName
    -- Or
    SELECT MyColName = 1  
    -- Etc...
)

Q 2) now here about CTE and recursion of employee relation the moment i add two manager and add few more employee under second manager then problem start. i want to display first manager detail and in the next rows only those employee details will come those who are subordinate of that manager

A2:

Please run the below query, it doesn't requires STUFF and GROUP BY in your case:

Select
      A.maskid
    , A.maskname
    , A.schoolid
    , B.schoolname
    , CAST((
          SELECT  T.maskdetail+','
          FROM dbo.maskdetails T
          WHERE A.maskid = T.maskid
          FOR XML PATH(''))as varchar(max)) as maskdetail 
FROM dbo.tblmask A
JOIN dbo.school B ON B.ID = A.schoolid

Insert pull-right into the class attribute and let bootstrap arrange the buttons.

For Bootstrap 2.3, see: http://getbootstrap.com/2.3.2/components.html#misc > Helper classes > .pull-right.

For Bootstrap 3, see: https://getbootstrap.com/docs/3.3/css/#helper-classes > Helper classes.

For Bootstrap 4, see: https://getbootstrap.com/docs/4.0/utilities/float/#responsive

The pull-right command was removed and replaced with float-right or in general to float-{sm,md,lg,xl}-{left,right,none}

Perhaps setOnClickListener(null) ?

Snowflake/Teradata supports QUALIFY clause which works like HAVING for windowed functions:

SELECT id, customer, total
FROM PURCHASES
QUALIFY ROW_NUMBER() OVER(PARTITION BY p.customer ORDER BY p.total DESC) = 1

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

If you are using a GUI and you are still getting the same problem. Just leave the size value empty, the primary key defaults the value to 11, you should be fine with this. Worked with Bitnami phpmyadmin.

Calendar cal = Calendar.getInstance();
   DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
   System.out.println("Today's date is "+dateFormat.format(cal.getTime()));

   cal.add(Calendar.DATE, -1);
   System.out.println("Yesterday's date was "+dateFormat.format(cal.getTime())); 

Well, it's not a single statement, but it's about as close as you can get with oracle:

BEGIN
   FOR R IN (SELECT owner, table_name FROM all_tables WHERE owner='TheOwner') LOOP
      EXECUTE IMMEDIATE 'grant select on '||R.owner||'.'||R.table_name||' to TheUser';
   END LOOP;
END; 

I this answer to setup a combo box from an enum attributes which was great.

I then needed to code the reverse so that I can get the selection from the box and return the enum in the correct type.

I also modified the code to handle the case where an attribute was missing

For the benefits of the next person, here is my final solution

public static class Program
{
   static void Main(string[] args)
    {
       // display the description attribute from the enum
       foreach (Colour type in (Colour[])Enum.GetValues(typeof(Colour)))
       {
            Console.WriteLine(EnumExtensions.ToName(type));
       }

       // Get the array from the description
       string xStr = "Yellow";
       Colour thisColour = EnumExtensions.FromName<Colour>(xStr);

       Console.ReadLine();
    }

   public enum Colour
   {
       [Description("Colour Red")]
       Red = 0,

       [Description("Colour Green")]
       Green = 1,

       [Description("Colour Blue")]
       Blue = 2,

       Yellow = 3
   }
}

public static class EnumExtensions
{

    // This extension method is broken out so you can use a similar pattern with 
    // other MetaData elements in the future. This is your base method for each.
    public static T GetAttribute<T>(this Enum value) where T : Attribute
    {
        var type = value.GetType();
        var memberInfo = type.GetMember(value.ToString());
        var attributes = memberInfo[0].GetCustomAttributes(typeof(T), false);

        // check if no attributes have been specified.
        if (((Array)attributes).Length > 0)
        {
            return (T)attributes[0];
        }
        else
        {
            return null;
        }
    }

    // This method creates a specific call to the above method, requesting the
    // Description MetaData attribute.
    public static string ToName(this Enum value)
    {
        var attribute = value.GetAttribute<DescriptionAttribute>();
        return attribute == null ? value.ToString() : attribute.Description;
    }

    /// <summary>
    /// Find the enum from the description attribute.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="desc"></param>
    /// <returns></returns>
    public static T FromName<T>(this string desc) where T : struct
    {
        string attr;
        Boolean found = false;
        T result = (T)Enum.GetValues(typeof(T)).GetValue(0);

        foreach (object enumVal in Enum.GetValues(typeof(T)))
        {
            attr = ((Enum)enumVal).ToName();

            if (attr == desc)
            {
                result = (T)enumVal;
                found = true;
                break;
            }
        }

        if (!found)
        {
            throw new Exception();
        }

        return result;
    }
}

}

This looks like a situation for producer-consumer pattern. If you’re using java 5 or up, you may consider using blocking queue(java.util.concurrent.BlockingQueue) and leave the thread coordination work to the underlying framework/api implementation. See the example from java 5: http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/BlockingQueue.html or java 7 (same example): http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/BlockingQueue.html

Here's another canvas based version with variable width (based on drawing velocity) curves: demo at http://szimek.github.io/signature_pad and code at https://github.com/szimek/signature_pad.

Change IDs and data attributes as you wish!

  <select id="selectVehicle">
       <option value="1" data-year="2011">Mazda</option>
       <option value="2" data-year="2015">Honda</option>
       <option value="3" data-year="2008">Mercedes</option>
       <option value="4" data-year="2005">Toyota</option>
  </select>

$("#selectVehicle").change(function () {
     alert($(this).find(':selected').data("year"));
});

Here is the working example: https://jsfiddle.net/ed5axgvk/1/

Fast method : (new foobar())->foobarfunc();

You need to load your class replace :

foobar::foobarfunc();

by :

(new foobar())->foobarfunc();

or :

$Foobar = new foobar();
$Foobar->foobarfunc();

Or make static function to use foobar::.

class foobar {
    //...

    static function foobarfunc() {
        return $this->foo();
    }
}

This is some really cool stuff! I needed pretty much the same, but with horizontal gradient from white to transparent. And it is working just fine! Here ist my code:

.gradient{
        /* webkit example */
        background-image: -webkit-gradient(
          linear, right top, left top, from(rgba(255, 255, 255, 1.0)),
          to(rgba(255, 255, 255, 0))
        );

        /* mozilla example - FF3.6+ */
        background-image: -moz-linear-gradient(
          right center,
          rgba(255, 255, 255, 1.0) 20%, rgba(255, 255, 255, 0) 95%
        );

        /* IE 5.5 - 7 */
        filter: progid:DXImageTransform.Microsoft.gradient(
          gradientType=1, startColor=0, endColorStr=#FFFFFF
        );

        /* IE8 uses -ms-filter for whatever reason... */
        -ms-filter: progid:DXImageTransform.Microsoft.gradient(
          gradientType=1, startColor=0, endColoStr=#FFFFFF
        );
    }

For those of you who share my weird fondness of manually editing config files, adding (or modifying) the following would also do the trick.

.git/config (personal config)

[submodule "cookbooks/apt"]
    url = https://github.com/opscode-cookbooks/apt

.gitmodules (committed shared config)

[submodule "cookbooks/apt"]
    path = cookbooks/apt
    url = https://github.com/opscode-cookbooks/apt

See this as well - difference between .gitmodules and specifying submodules in .git/config?

For Python 3, I'm using this function:

def user_prompt(question: str) -> bool:
    """ Prompt the yes/no-*question* to the user. """
    from distutils.util import strtobool

    while True:
        user_input = input(question + " [y/n]: ")
        try:
            return bool(strtobool(user_input))
        except ValueError:
            print("Please use y/n or yes/no.\n")

The strtobool() function converts a string into a bool. If the string cant be parsed it will raise a ValueError.

In Python 3 raw_input() has been renamed to input().

As Geoff said, strtobool actually returns 0 or 1, therefore the result has to be cast to bool.

This is the implementation of strtobool, if you want special words to be recognized as true, you can copy the code and add your own cases.

def strtobool (val):
    """Convert a string representation of truth to true (1) or false (0).
    True values are 'y', 'yes', 't', 'true', 'on', and '1'; false values
    are 'n', 'no', 'f', 'false', 'off', and '0'.  Raises ValueError if
    'val' is anything else.
    """
    val = val.lower()
    if val in ('y', 'yes', 't', 'true', 'on', '1'):
        return 1
    elif val in ('n', 'no', 'f', 'false', 'off', '0'):
        return 0
    else:
        raise ValueError("invalid truth value %r" % (val,))

I normally configure the applicationContext using Annotation based configuration rather than XML based configuration. Anyway, I believe both of them have the same priority.

*Answering your question, system variable has higher priority *

Getting profile based beans from applicationContext

• Use @Profile on a Bean

@Component
@Profile("dev")
public class DatasourceConfigForDev

Now, the profile is dev

Note : if the Profile is given as @Profile("!dev") then the profile will exclude dev and be for all others.

• Use profiles attribute in XML

<beans profile="dev">
    <bean id="DatasourceConfigForDev" class="org.skoolguy.profiles.DatasourceConfigForDev"/>
</beans>

Set the value for profile:

• Programmatically via WebApplicationInitializer interface

  In web applications, WebApplicationInitializer can be used to configure the ServletContext programmatically

@Configuration
public class MyWebApplicationInitializer implements WebApplicationInitializer {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
            servletContext.setInitParameter("spring.profiles.active", "dev");
    }
}

• Programmatically via ConfigurableEnvironment

  You can also set profiles directly on the environment:

    @Autowired
    private ConfigurableEnvironment env;

    // ...

    env.setActiveProfiles("dev");

• Context Parameter in web.xml

  profiles can be activated in the web.xml of the web application as well, using a context parameter:

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/app-config.xml</param-value>
    </context-param>
    <context-param>
        <param-name>spring.profiles.active</param-name>
        <param-value>dev</param-value>
    </context-param>

• JVM System Parameter

  The profile names passed as the parameter will be activated during application start-up:

  -Dspring.profiles.active=dev
  

  In IDEs, you can set the environment variables and values to use when an application runs. The following is the Run Configuration in Eclipse:

• Environment Variable

  to set via command line : export spring_profiles_active=dev

Any bean that does not specify a profile belongs to “default” profile.

The priority order is :

1. Context parameter in web.xml
2. WebApplicationInitializer
3. JVM System parameter
4. Environment variable

You're probably missing some dependencies.

Locate the dependencies you're missing with mvn dependency:tree, then install them manually, and build your project with the -o (offline) option.
