in your CFG file please change the hibernate dialect

I can't comment on the accepted answer, due to low reputation. However, I would like to add, this behavior is by design. The NodeManager is killing your container. It sounds like you are trying to use hadoop streaming which is running as a child process of the map-reduce task. The NodeManager monitors the entire process tree of the task and if it eats up more memory than the maximum set in mapreduce.map.memory.mb or mapreduce.reduce.memory.mb respectively, we would expect the Nodemanager to kill the task, otherwise your task is stealing memory belonging to other containers, which you don't want.

[Update]

The original answer was written prior to jQuery 1.3, and the functions that existed at the time where not adequate by themselves to calculate the whole width.

Now, as J-P correctly states, jQuery has the functions outerWidth and outerHeight which include the border and padding by default, and also the margin if the first argument of the function is true

[Original answer]

The width method no longer requires the dimensions plugin, because it has been added to the jQuery Core

What you need to do is get the padding, margin and border width-values of that particular div and add them to the result of the width method

Something like this:

var theDiv = $("#theDiv");
var totalWidth = theDiv.width();
totalWidth += parseInt(theDiv.css("padding-left"), 10) + parseInt(theDiv.css("padding-right"), 10); //Total Padding Width
totalWidth += parseInt(theDiv.css("margin-left"), 10) + parseInt(theDiv.css("margin-right"), 10); //Total Margin Width
totalWidth += parseInt(theDiv.css("borderLeftWidth"), 10) + parseInt(theDiv.css("borderRightWidth"), 10); //Total Border Width

Split into multiple lines to make it more readable

That way you will always get the correct computed value, even if you change the padding or margin values from the css

Recommended is to use JSON.parse

There is an alternative you can do :

 var myObject = eval('(' + myJSONtext + ')');

Json in javascript

Why is using the JavaScript eval function a bad idea?

Ideally, I would use a construct like this instead:

for (std::vector<your_type>::const_iterator i = things.begin(); i != things.end(); ++i)
{
  // if you ever need the distance, you may call std::distance
  // it won't cause any overhead because the compiler will likely optimize the call
  size_t distance = std::distance(things.begin(), i);
}

This a has the neat advantage that your code suddenly becomes container agnostic.

And regarding your problem, if some library you use requires you to use int where an unsigned int would better fit, their API is messy. Anyway, if you are sure that those int are always positive, you may just do:

int int_distance = static_cast<int>(distance);

Which will specify clearly your intent to the compiler: it won't bug you with warnings anymore.

This is a confusion between constructors and instances.

Remember that when you write a component in React:

class Greeter extends React.Component<any, any> {
    render() {
        return <div>Hello, {this.props.whoToGreet}</div>;
    }
}

You use it this way:

return <Greeter whoToGreet='world' />;

You don't use it this way:

let Greet = new Greeter();
return <Greet whoToGreet='world' />;

In the first example, we're passing around Greeter, the constructor function for our component. That's the correct usage. In the second example, we're passing around an instance of Greeter. That's incorrect, and will fail at runtime with an error like "Object is not a function".

The problem with this code

function renderGreeting(Elem: React.Component<any, any>) {
    return <span>Hello, <Elem />!</span>;
}

is that it's expecting an instance of React.Component. What you want is a function that takes a constructor for React.Component:

function renderGreeting(Elem: new() => React.Component<any, any>) {
    return <span>Hello, <Elem />!</span>;
}

or similarly:

function renderGreeting(Elem: typeof React.Component) {
    return <span>Hello, <Elem />!</span>;
}

There's most likely a more elegant way, but this does find every record with a letter in it, both upper or lower case:

select * from your_table
where UPPER(your_field) like '%A%'
or UPPER(your_field) like '%B%'
or UPPER(your_field) like '%C%'
or UPPER(your_field) like '%D%'
or UPPER(your_field) like '%E%'
or UPPER(your_field) like '%F%'
or UPPER(your_field) like '%G%'
or UPPER(your_field) like '%H%'
or UPPER(your_field) like '%I%'
or UPPER(your_field) like '%J%'
or UPPER(your_field) like '%K%'
or UPPER(your_field) like '%L%'
or UPPER(your_field) like '%M%'
or UPPER(your_field) like '%N%'
or UPPER(your_field) like '%O%'
or UPPER(your_field) like '%P%'
or UPPER(your_field) like '%Q%'
or UPPER(your_field) like '%R%'
or UPPER(your_field) like '%S%'
or UPPER(your_field) like '%T%'
or UPPER(your_field) like '%U%'
or UPPER(your_field) like '%V%'
or UPPER(your_field) like '%W%'
or UPPER(your_field) like '%X%'
or UPPER(your_field) like '%Y%'
or UPPER(your_field) like '%Z%'

But be careful. A PL/SQL function will only search the first 32K of LONG.

I just do this way :

if let myView = UINib.init(nibName: "MyView", bundle: nil).instantiate(withOwner: self)[0] as? MyView {
    // Do something with myView
}

This sample uses the first view in the nib "MyView.xib" in the main bundle. But you can vary either the index, the nib name, or the bundle ( main by default ).

I used to awake views into the view init method or make generic methods as in the proposed answers above ( which are smart by the way ), but I don't do it anymore because I have noticed use cases are often different, and to cover all cases, generic methods become as complex as using the UINib.instantiate method.

I prefer to use a factory object, usually the ViewController that will use the view, or a dedicated factory object or view extension if the view needs to be used in multiple places.

In this example, a ViewController loads a view from nib. The nib file can be changed to use different layouts for the same view class. ( This not nice code, it just illustrates the idea )

class MyViewController {
    // Use "MyView-Compact" for compact version
    var myViewNibFileName = "MyView-Standard"

    lazy var myView: MyView = {
        // Be sure the Nib is correct, or it will crash
        // We don't want to continue with a wrong view anyway, so ! is ok
        UINib.init(nibName: myViewNibFileName, bundle: nil).instantiate(withOwner: self)[0] as! MyView
    }()
}

Divide and Conquer

• In this problem is solved in following three steps: 1. Divide - Dividing into number of sub-problems 2. Conquer - Conquering by solving sub-problems recursively 3. Combine - Combining sub-problem solutions to get original problem's solution
• Recursive approach
• Top Down technique
• Example: Merge Sort

Dynamic Programming

• In this the problem is solved in following steps: 1. Defining structure of optimal solution 2. Defines value of optimal solutions repeatedly. 3. Obtaining values of optimal solution in bottom-up fashion 4. Getting final optimal solution from obtained values
• Non-Recursive
• Bottom Up Technique
• Example: Strassen's Matrix Multiplication

$parent doesn't work if there are multiple parents. instead of that we can define a parent index variable in init and use it

<div data-ng-init="parentIndex = $index" ng-repeat="f in foos">
  <div>
    <div data-ng-init="childIndex = $index" ng-repeat="b in foos.bars">
      <a ng-click="addSomething(parentIndex)">Add Something</a>
    </div>
  </div>
</div>

You can use this function that gets promiseFactories List:

function executeSequentially(promiseFactories) {
    var result = Promise.resolve();
    promiseFactories.forEach(function (promiseFactory) {
        result = result.then(promiseFactory);
    });
    return result;
}

Promise Factory is just simple function that returns a Promise:

function myPromiseFactory() {
    return somethingThatCreatesAPromise();
}

It works because a promise factory doesn't create the promise until it's asked to. It works the same way as a then function – in fact, it's the same thing!

You don't want to operate over an array of promises at all. Per the Promise spec, as soon as a promise is created, it begins executing. So what you really want is an array of promise factories...

sumall = summ + sumd + sumy

Your sumall is an integer. If you want the individual characters from it, convert it to a string first.

The Chrome CSS property -webkit-print-color-adjust: exact; works appropriately.

However, making sure you have the correct CSS for printing can often be tricky. Several things can be done to avoid the difficulties you are having. First, separate all your print CSS from your screen CSS. This is done via the @media print and @media screen.

Often times just setting up some extra @media print CSS is not enough because you still have all your other CSS included when printing as well. In these cases you just need to be aware of CSS specificity as the print rules don't automatically win against non-print CSS rules.

In your case, the -webkit-print-color-adjust: exact is working. However, your background-color and color definitions are being beaten out by other CSS with higher specificity.

While I do not endorse using !important in nearly any circumstance, the following definitions work properly and expose the problem:

@media print {
    tr.vendorListHeading {
        background-color: #1a4567 !important;
        -webkit-print-color-adjust: exact; 
    }
}

@media print {
    .vendorListHeading th {
        color: white !important;
    }
}

Here is the fiddle (and embedded for ease of print previewing).

You can just use the -R (recursive) flag.

Looks like no, though it was requested, and there’s a UDF for it.

Edit: Or there’s… this. Ugh.

Well, you may read System.in itself as it is a valid InputStream. Or also you can wrap it in a BufferedReader:

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

Try redirecting the output to Out-Null. Like so,

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null

Never, never, never say

if something == True:

Never. It's crazy, since you're redundantly repeating what is redundantly specified as the redundant condition rule for an if-statement.

Worse, still, never, never, never say

if something == False:

You have not. Feel free to use it.

Finally, doing a == None is inefficient. Do a is None. None is a special singleton object, there can only be one. Just check to see if you have that object.

I found exellent solution on http://habrahabr.ru/post/164945/

public class ResourceQuery
{
   public string Param1 { get; set; }
   public int OptionalParam2 { get; set; }
}

public class SampleResourceController : ApiController
{
    public SampleResourceModel Get([FromUri] ResourceQuery query)
    {
        // action
    }
}

Use:

#include <iostream>

...

std::cout << std::hex << a;

There are many other options to control the exact formatting of the output number, such as leading zeros and upper/lower case.

anyItem is a method and the System.out.println call is after your return statement so that won't compile anyway since it is unreachable.

Might want to re-write it like:

import java.util.ArrayList;
import java.util.Random;

public class Catalogue
{
    private Random randomGenerator;
    private ArrayList<Item> catalogue;

    public Catalogue()
    { 
        catalogue = new ArrayList<Item>();
        randomGenerator = new Random();
    }

    public Item anyItem()
    {
        int index = randomGenerator.nextInt(catalogue.size());
        Item item = catalogue.get(index);
        System.out.println("Managers choice this week" + item + "our recommendation to you");
        return item;
    }
}

You need to call self.a() to invoke a from b. a is not a global function, it is a method on the class.

You may want to read through the Python tutorial on classes some more to get the finer details down.

For IntelliJ 20.1 or above, on Mac OSX:

IntelliJ IDEA -> Editor -> General -> Appearance -> Show line numbers

Point to be noted: Always look for Editor

For shortcut:

? + ? + A (command + shift + A)

type

and click on the pop up to turn on Show line numbers and you are good to go.

Functional decision for @pegah answer:

from itertools import groupby

mylist = [('a', 1), ('b', 3), ('a', 2), ('b', 4)]
#mylist = iter([('a', 1), ('b', 3), ('a', 2), ('b', 4)])

result = { k : [*map(lambda v: v[1], values)]
    for k, values in groupby(sorted(mylist, key=lambda x: x[0]), lambda x: x[0])
    }

print(result)
# {'a': [1, 2], 'b': [3, 4]}

wanna very, very comfortable 1 minute solution?

just you this app https://play.google.com/store/apps/details?id=com.cvinfo.filemanager (smart file manager from google play).

tap "apps", choose one and tap "backup". it will end up on your file system in app_backup folder ;)

Assuming both lists a and b have same length, you do not need zip, numpy or anything else.

Python 2.x and 3.x:

[a[i]+b[i] for i in range(len(a))]

Lots of potential solutions, but let's add just one more. Use Jackson (JSON processing lib) to do "json-less" conversion, like:

ObjectMapper m = new ObjectMapper();
Map<String,Object> props = m.convertValue(myBean, Map.class);
MyBean anotherBean = m.convertValue(props, MyBean.class);

(this blog entry has some more examples)

You can basically convert any compatible types: compatible meaning that if you did convert from type to JSON, and from that JSON to result type, entries would match (if configured properly can also just ignore unrecognized ones).

Works well for cases one would expect, including Maps, Lists, arrays, primitives, bean-like POJOs.

You have to do two things:

• be sure to have imported right appcompat-v7 library in your project structure -> dependencies
• change the theme in the preview window to not an AppCompat theme. Try with Holo.light or Holo.dark for example.

with open(fpath, 'rb') as myfile:
    fstr = myfile.read()

I encounter this error because the file is empty. This answer may not a correct answer for this question but should give developers a hint like me.

I finally managed to create a query that does exactly what i wanted to have:

A filtered nested boolean query. I am not sure why this is not documented. Maybe someone here can tell me?

Here is the query:

GET /test/object/_search

    "_score": "desc"
  },

                    }
                  }
                ]
              }
            }

          "minimum_should_match": 1
        }
      }    
    }
  }
}

In pseudo-SQL:

SELECT * FROM /test/object
WHERE 
    ((name=foo AND name=bar) OR (info=foo AND info=bar))
AND state=1

Please keep in mind that it depends on your document field analysis and mappings how name=foo is internally handled. This can vary from a fuzzy to strict behavior.

"minimum_should_match": 1 says, that at least one of the should statements must be true.

This statements means that whenever there is a document in the resultset that contains has_image:1 it is boosted by factor 100. This changes result ordering.

"should": [
  {
    "match": {
      "has_image": {
        "query": 1,
        "boost": 100
      }
    }
   }
 ]

Have fun guys :)

You use this style code

.heighttext{
 float:right;
 height:30px;
 width:70px;
 }

public void addNotification()
{
    NotificationCompat.Builder mBuilder=new NotificationCompat.Builder(MainActivity.this);
    mBuilder.setSmallIcon(R.drawable.email);
    mBuilder.setContentTitle("Notification Alert, Click Me!");
    mBuilder.setContentText("Hi,This notification for you let me check");
    Intent notificationIntent = new Intent(this,MainActivity.class);
    PendingIntent conPendingIntent = PendingIntent.getActivity(this,0,notificationIntent,PendingIntent.FLAG_UPDATE_CURRENT);

    mBuilder.setContentIntent(conPendingIntent);

    NotificationManager manager=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
    manager.notify(0,mBuilder.build());
    Toast.makeText(MainActivity.this, "Notification", Toast.LENGTH_SHORT).show();

}

If you're going to be using this often (and on multiple arrays), extend the Array object to create an unset function.

Array.prototype.unset = function(value) {
    if(this.indexOf(value) != -1) { // Make sure the value exists
        this.splice(this.indexOf(value), 1);
    }   
}

tag_story.unset(56)

PriceList[0] is a float. PriceList[0][1] is trying to access the first element of a float. Instead, do

PriceList[0] = PriceList[1] = ...code omitted... = PriceList[6] = PizzaChange

or

PriceList[0:7] = [PizzaChange]*7

You can also achieve it by using StadiumBorder shape

FlatButton(
  onPressed: () {},
  child: Text('StadiumBorder'),
  shape: StadiumBorder(),
  color: Colors.pink,
  textColor: Colors.white,
),

Not the most readable solution, but you can mix the result from a value-of with plain text:

<a>
  <xsl:attribute name="href"> 
    Text<xsl:value-of select="/*/properties/property[@name='report']/@value"/>Text
  </xsl:attribute>
</a>

Have a Table class whose rows is a list of dict or better row objects

In table do not directly add rows but have a method which update few lookup maps e.g. for name if you are not adding rows in order or id are not consecutive you can have idMap too e.g.

class Table(object):
    def __init__(self):
        self.rows =  []# list of row objects, we assume if order of id
        self.nameMap = {} # for faster direct lookup for row by name

    def addRow(self, row):
        self.rows.append(row)
        self.nameMap[row['name']] = row

    def getRow(self, name):
        return self.nameMap[name]


table = Table()
table.addRow({'ID':1,'name':'a'})

If you want to start afresh, deleting the settings.json file from your user's profile will do the trick.

But if you don't want to reset everything, it is still possible through settings menu.

You can search for the setting that you want to revert back using search box.

You will see some settings with the left blue line, it means you've modified that one.

If you take your cursor to that setting, a gear button will appear. You can click this to restore that setting.

You can also use the drop-down below that setting and change it to default.

This is actually pretty simple

1. Install virtual box and vagrant on the remote machine

2. Wrap up your vagrant machine

   vagrant package --base [machine name as it shows in virtual box] --output /Users/myuser/Documents/Workspace/my.box

3. copy the box to your remote

4. init the box on your remote machine by running

   vagrant init [machine name as it shows in virtual box] /Users/myuser/Documents/Workspace/my.box

5. Run vagrant up

I came across the same issue as well. Not sure why this is working but it indeed works: Try add ENGINE INNODB after your create query.

mysql> create table course
-> (course_id varchar(7),
-> title varchar (50),
-> dept_name varchar(20),
-> credits numeric(2,0),
-> primary key(course_id),
-> foreign key (dept_name) references department) ENGINE INNODB;

If you want to restrict valid input to integer values between 1 and 100, this will do it:

^([1-9]|[1-9][0-9]|100)$

Explanation:

1. ^ = start of input
2. () = multiple options to match
3. First argument [1-9] - matches any entries between 1 and 9
4. | = OR argument separator
5. Second Argument [1-9][0-9] - matches entries between 10 and 99
6. Last Argument 100 - Self explanatory - matches entries of 100

This WILL NOT ACCEPT: 1. Zero - 0 2. Any integer preceded with a zero - 01, 021, 001 3. Any integer greater than 100

Hope this helps!

If you put position:relative; on the outer element, the inner element will place itself according to this one. Then a width:auto; on the inner element will be the same as the width of the outer.

Two more ways that do not depend on the time settings (both taken from How get data/time independent from localization). And both also get the day of the week and none of them requires admin permissions!:

1. MAKECAB - will work on EVERY Windows system (fast, but creates a small temporary file) (the foxidrive script):

   @echo off
   pushd "%temp%"
   makecab /D RptFileName=~.rpt /D InfFileName=~.inf /f nul >nul
   for /f "tokens=3-7" %%a in ('find /i "makecab"^<~.rpt') do (
       set "current-date=%%e-%%b-%%c"
       set "current-time=%%d"
       set "weekday=%%a"
   )
   del ~.*
   popd
   echo %weekday% %current-date% %current-time%
   pause
   

2. ROBOCOPY - it's not a native command for Windows XP and Windows Server 2003, but it can be downloaded from the Microsoft site. But it is built-in in everything from Windows Vista and above:

   @echo off
   setlocal
   for /f "skip=8 tokens=2,3,4,5,6,7,8 delims=: " %%D in ('robocopy /l * \ \ /ns /nc /ndl /nfl /np /njh /XF * /XD *') do (
       set "dow=%%D"
       set "month=%%E"
       set "day=%%F"
       set "HH=%%G"
       set "MM=%%H"
       set "SS=%%I"
       set "year=%%J"
   )
   
   echo Day of the week: %dow%
   echo Day of the month : %day%
   echo Month : %month%
   echo hour : %HH%
   echo minutes : %MM%
   echo seconds : %SS%
   echo year : %year%
   endlocal
   

   And three more ways that uses other Windows script languages. They will give you more flexibility e.g. you can get week of the year, time in milliseconds and so on.

3. JScript/BATCH hybrid (need to be saved as .bat). JScript is available on every system from Windows NT and above, as a part of Windows Script Host (though can be disabled through the registry it's a rare case):

   @if (@X)==(@Y) @end /* ---Harmless hybrid line that begins a JScript comment
   
   @echo off
   cscript //E:JScript //nologo "%~f0"
   exit /b 0
   *------------------------------------------------------------------------------*/
   
   function GetCurrentDate() {
       // Today date time which will used to set as default date.
       var todayDate = new Date();
       todayDate = todayDate.getFullYear() + "-" +
                      ("0" + (todayDate.getMonth() + 1)).slice(-2) + "-" +
                      ("0" + todayDate.getDate()).slice(-2) + " " + ("0" + todayDate.getHours()).slice(-2) + ":" +
                      ("0" + todayDate.getMinutes()).slice(-2);
   
       return todayDate;
   }
   
   WScript.Echo(GetCurrentDate());
   

4. VBScript/BATCH hybrid (Is it possible to embed and execute VBScript within a batch file without using a temporary file?) same case as jscript , but hybridization is not so perfect:

   :sub echo(str) :end sub
   echo off
   '>nul 2>&1|| copy /Y %windir%\System32\doskey.exe %windir%\System32\'.exe >nul
   '& echo current date:
   '& cscript /nologo /E:vbscript "%~f0"
   '& exit /b
   
   '0 = vbGeneralDate - Default. Returns date: mm/dd/yy and time if specified: hh:mm:ss PM/AM.
   '1 = vbLongDate - Returns date: weekday, monthname, year
   '2 = vbShortDate - Returns date: mm/dd/yy
   '3 = vbLongTime - Returns time: hh:mm:ss PM/AM
   '4 = vbShortTime - Return time: hh:mm
   
   WScript.echo  Replace(FormatDateTime(Date, 1), ", ", "-")
   

5. PowerShell - can be installed on every machine that has .NET - download from Microsoft (v1, v2, and v3 (only for Windows 7 and above)). Installed by default on everything form Windows 7/Win2008 and above:

   C:\> powershell get-date -format "{dd-MMM-yyyy HH:mm}"
   

6. Self-compiled jscript.net/batch (I have never seen a Windows machine without .NET so I think this is a pretty portable):

   @if (@X)==(@Y) @end /****** silent line that start jscript comment ******
   
   @echo off
   ::::::::::::::::::::::::::::::::::::
   :::       Compile the script    ::::
   ::::::::::::::::::::::::::::::::::::
   setlocal
   if exist "%~n0.exe" goto :skip_compilation
   
   set "frm=%SystemRoot%\Microsoft.NET\Framework\"
   :: searching the latest installed .net framework
   for /f "tokens=* delims=" %%v in ('dir /b /s /a:d /o:-n "%SystemRoot%\Microsoft.NET\Framework\v*"') do (
       if exist "%%v\jsc.exe" (
           rem :: the javascript.net compiler
           set "jsc=%%~dpsnfxv\jsc.exe"
           goto :break_loop
       )
   )
   echo jsc.exe not found && exit /b 0
   :break_loop
   
   
   call %jsc% /nologo /out:"%~n0.exe" "%~dpsfnx0"
   ::::::::::::::::::::::::::::::::::::
   :::       End of compilation    ::::
   ::::::::::::::::::::::::::::::::::::
   :skip_compilation
   
   "%~n0.exe"
   
   exit /b 0
   
   
   ****** End of JScript comment ******/
   import System;
   import System.IO;
   
   var dt=DateTime.Now;
   Console.WriteLine(dt.ToString("yyyy-MM-dd hh:mm:ss"));
   

7. Logman This cannot get the year and day of the week. It's comparatively slow, also creates a temp file and is based on the time stamps that logman puts on its log files.Will work everything from Windows XP and above. It probably will be never used by anybody - including me - but it is one more way...

   @echo off
   setlocal
   del /q /f %temp%\timestampfile_*
   
   Logman.exe stop ts-CPU 1>nul 2>&1
   Logman.exe delete ts-CPU 1>nul 2>&1
   
   Logman.exe create counter ts-CPU  -sc 2 -v mmddhhmm -max 250 -c "\Processor(_Total)\%% Processor Time" -o %temp%\timestampfile_ >nul
   Logman.exe start ts-CPU 1>nul 2>&1
   
   Logman.exe stop ts-CPU >nul 2>&1
   Logman.exe delete ts-CPU >nul 2>&1
   for /f "tokens=2 delims=_." %%t in  ('dir /b %temp%\timestampfile_*^&del /q/f %temp%\timestampfile_*') do set timestamp=%%t
   
   echo %timestamp%
   echo MM: %timestamp:~0,2%
   echo dd: %timestamp:~2,2%
   echo hh: %timestamp:~4,2%
   echo mm: %timestamp:~6,2%
   
   endlocal
   exit /b 0

I've create a ClassPathResourceReader class in a java 8 way to make easy read files from classpath

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.stream.Collectors;

import org.springframework.core.io.ClassPathResource;

public final class ClassPathResourceReader {

    private final String path;

    private String content;

    public ClassPathResourceReader(String path) {
        this.path = path;
    }

    public String getContent() {
        if (content == null) {
            try {
                ClassPathResource resource = new ClassPathResource(path);
                BufferedReader reader = new BufferedReader(new InputStreamReader(resource.getInputStream()));
                content = reader.lines().collect(Collectors.joining("\n"));
                reader.close();
            } catch (IOException ex) {
                throw new RuntimeException(ex);
            }
        }
        return content;
    }
}

Utilization:

String content = new ClassPathResourceReader("data.sql").getContent();

You won't find C# running on any consoles, so it's useless in that regard.

If you are learning programming, C# offers a softer learning curve than C++, but you can write C++ without getting into the more scary and complex areas of the language, so it's not really much more difficult.

If you want to program with graphics or other "gamesey" things, then C# is a pretty poor choice - go for C++ with OpenGL or DirectX.

edit

Ultimately, if you want a career in games, go for C++. You may be able to write game code in C#, but realistically you won't find nearly as many career opportunities using C# as you do with C++. Unless you want to become a game tools programmer, in which case C# is much better than C++ because you can get a lot more functionality working in a lot less time. A lot of games companies are switching to C# for as much tools dev as possible.

Of course, if you can handle the workload, the best way is to learn both languages, and apply "the best tool for the job". As they're so similar, it's really not difficult to learn one when you've learned the other. (Really most of the learning curve moving from C++ to C# is .net and LINQ etc rather than the core C# language per se - an awful lot of it is nearly identical, with just a few bits of syntactical sugar here and there)

You can .split() to get an array of strings, then loop through to convert them to numbers, like this:

var myArray = "14 2".split(" ");
for(var i=0; i<myArray.length; i++) { myArray[i] = +myArray[i]; } 
//use myArray, it's an array of numbers

The +myArray[i] is just a quick way to do the number conversion, if you're sure they're integers you can just do:

for(var i=0; i<myArray.length; i++) { myArray[i] = parseInt(myArray[i], 10); } 

for (int i = 0; i < dataGridView2.Rows.Count; i++)
{
SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=ID_Proof;Integrated Security=True");
                        SqlCommand cmd = new SqlCommand("INSERT INTO Restaurant (Customer_Name,Quantity,Price,Category,Subcategory,Item,Room_No,Tax,Service_Charge,Service_Tax,Order_Time) values (@customer,@quantity,@price,@category,@subcategory,@item,@roomno,@tax,@servicecharge,@sertax,@ordertime)", con);
                        cmd.Parameters.AddWithValue("@customer",dataGridView2.Rows[i].Cells[0].Value);
                        cmd.Parameters.AddWithValue("@quantity",dataGridView2.Rows[i].Cells[1].Value);
                        cmd.Parameters.AddWithValue("@price",dataGridView2.Rows[i].Cells[2].Value);
                        cmd.Parameters.AddWithValue("@category",dataGridView2.Rows[i].Cells[3].Value);
                        cmd.Parameters.AddWithValue("@subcategory",dataGridView2.Rows[i].Cells[4].Value);
                        cmd.Parameters.AddWithValue("@item",dataGridView2.Rows[i].Cells[5].Value);
                        cmd.Parameters.AddWithValue("@roomno",dataGridView2.Rows[i].Cells[6].Value);
                        cmd.Parameters.AddWithValue("@tax",dataGridView2.Rows[i].Cells[7].Value);

                        cmd.Parameters.AddWithValue("@sertax",dataGridView2.Rows[i].Cells[9].Value);
                        cmd.Parameters.AddWithValue("@ordertime",dataGridView2.Rows[i].Cells[10].Value);
                        con.Open();
                        cmd.ExecuteNonQuery();
                        con.Close();
                        MessageBox.Show("Added successfully!");

I think it is a problem(aka. bug) with the API you are using. JSONArray implements Collection (the json.org implementation from which this API is derived does not have JSONArray implement Collection). And JSONObject has an overloaded put() method which takes a Collection and wraps it in a JSONArray (thus causing the problem). I think you need to force the other JSONObject.put() method to be used:

    jsonObject.put("aoColumnDefs",(Object)arr);

You should file a bug with the vendor, pretty sure their JSONObject.put(String,Collection) method is broken.

When using -c command, as a tricky way, instead of reading the stdin (and more flexible in some cases) you can pass a shell script command as well to your python command by putting the shell command in quotes within a parenthesis started by $ sign.

e.g.

python3 -c "import sys; print(len(sys.argv[1].split('\n')))" "$(cat ~/.goldendict/history)"

This will count the number of lines from goldendict's history file.

You can iterate DefaultView as the following code by Indexer:

DataTable dt = new DataTable();
// add some rows to your table
// ...
dt.DefaultView.Sort = "OneColumnName ASC"; // For example
for (int i = 0; i < dt.Rows.Count; i++)
{
    DataRow oRow = dt.DefaultView[i].Row;
    // Do your stuff with oRow
    // ...
}

Converting a JSON String to Map

public static Map<String, Object> jsonString2Map( String jsonString ) throws JSONException{
        Map<String, Object> keys = new HashMap<String, Object>(); 

        org.json.JSONObject jsonObject = new org.json.JSONObject( jsonString ); // HashMap
        Iterator<?> keyset = jsonObject.keys(); // HM

        while (keyset.hasNext()) {
            String key =  (String) keyset.next();
            Object value = jsonObject.get(key);
            System.out.print("\n Key : "+key);
            if ( value instanceof org.json.JSONObject ) {
                System.out.println("Incomin value is of JSONObject : ");
                keys.put( key, jsonString2Map( value.toString() ));
            }else if ( value instanceof org.json.JSONArray) {
                org.json.JSONArray jsonArray = jsonObject.getJSONArray(key);
                //JSONArray jsonArray = new JSONArray(value.toString());
                keys.put( key, jsonArray2List( jsonArray ));
            } else {
                keyNode( value);
                keys.put( key, value );
            }
        }
        return keys;
    }

Converting JSON Array to List

public static List<Object> jsonArray2List( JSONArray arrayOFKeys ) throws JSONException{
        System.out.println("Incoming value is of JSONArray : =========");
        List<Object> array2List = new ArrayList<Object>();
        for ( int i = 0; i < arrayOFKeys.length(); i++ )  {
            if ( arrayOFKeys.opt(i) instanceof JSONObject ) {
                Map<String, Object> subObj2Map = jsonString2Map(arrayOFKeys.opt(i).toString());
                array2List.add(subObj2Map);
            }else if ( arrayOFKeys.opt(i) instanceof JSONArray ) {
                List<Object> subarray2List = jsonArray2List((JSONArray) arrayOFKeys.opt(i));
                array2List.add(subarray2List);
            }else {
                keyNode( arrayOFKeys.opt(i) );
                array2List.add( arrayOFKeys.opt(i) );
            }
        }
        return array2List;      
    }

Display JSON of Any Format

public static void displayJSONMAP( Map<String, Object> allKeys ) throws Exception{
        Set<String> keyset = allKeys.keySet(); // HM$keyset
        if (! keyset.isEmpty()) {
            Iterator<String> keys = keyset.iterator(); // HM$keysIterator
            while (keys.hasNext()) {
                String key = keys.next();
                Object value = allKeys.get( key );
                if ( value instanceof Map ) {
                    System.out.println("\n Object Key : "+key);
                        displayJSONMAP(jsonString2Map(value.toString()));                   
                }else if ( value instanceof List ) {
                    System.out.println("\n Array Key : "+key);
                    JSONArray jsonArray = new JSONArray(value.toString());
                    jsonArray2List(jsonArray);
                }else {
                    System.out.println("key : "+key+" value : "+value);
                }
            }
        }   

    }

Google.gson to HashMap.

Changing the web.config generally causes an application restart.

If you really need your application to edit its own settings, then you should consider a different approach such as databasing the settings or creating an xml file with the editable settings.

Update 2018

While everything written below still holds true, Rails 5.2 now includes active_storage, which allows stuff like uploading directly to S3 (or other cloud storage services), image transformations, etc. You should check out the rails guide and decide for yourself what fits your needs.

While there are plenty of gems that solve file uploading pretty nicely (see https://www.ruby-toolbox.com/categories/rails_file_uploads for a list), rails has built-in helpers which make it easy to roll your own solution.

Use the file_field-form helper in your form, and rails handles the uploading for you:

<%= form_for @person do |f| %>
  <%= f.file_field :picture %>
<% end %>

You will have access in the controller to the uploaded file as follows:

uploaded_io = params[:person][:picture]
File.open(Rails.root.join('public', 'uploads', uploaded_io.original_filename), 'wb') do |file|
  file.write(uploaded_io.read)
end

It depends on the complexity of what you want to achieve, but this is totally sufficient for easy file uploading/downloading tasks. This example is taken from the rails guides, you can go there for further information: http://guides.rubyonrails.org/form_helpers.html#uploading-files

This can be scripted in PL/SQL pretty simply based on the DBA/ALL/USER_CONSTRAINTS system view, but various details make not as trivial as it sounds. You have to be careful about the order in which it is done and you also have to take account of the presence of unique indexes.

The order is important because you cannot drop a unique or primary key that is referenced by a foreign key, and there could be foreign keys on tables in other schemas that reference primary keys in your own, so unless you have ALTER ANY TABLE privilege then you cannot drop those PKs and UKs. Also you cannot switch a unique index to being a non-unique index so you have to drop it in order to drop the constraint (for this reason it's almost always better to implement unique constraints as a "real" constraint that is supported by a non-unique index).

I was getting nothing for any $_GET["..."] (e.g print_r($_GET) gave an empty array) yet $_SERVER['REQUEST_URI'] showed stuff should be there. In the end it turned out that I was only getting to the web page because my .htaccess was redirecting it there (my 404 handler was the same .php file, and I had made a typo in the browser when testing).

Simply changing the name meant the same php code worked once the 404 redirection wasn't kicking in!

So there are ways $_GET can return nothing even though the php code may be correct.

Go to config/sessions.php

find the row

'secure' => env('SESSION_SECURE_COOKIE', true),

change it to false

'secure' => env('SESSION_SECURE_COOKIE', false),

If this parameter is set to TRUE browser will require you to use HTTPS protocol, otherwise it wont store the session. As it is not valid

I have done quite a bit of what you're talking about, and SOAP interoperability between platforms has one cardinal rule: CONTRACT FIRST. Do not derive your WSDL from code and then try to generate a client on a different platform. Anything more than "Hello World" type functions will very likely fail to generate code, fail to talk at runtime or (my favorite) fail to properly send or receive all of the data without raising an error.

That said, WSDL is complicated, nasty stuff and I avoid writing it from scratch whenever possible. Here are some guidelines for reliable interop of services (using Web References, WCF, Axis2/Java, WS02, Ruby, Python, whatever):

• Go ahead and do code-first to create your initial WSDL. Then, delete your code and re-generate the server class(es) from the WSDL. Almost every platform has a tool for this. This will show you what odd habits your particular platform has, and you can begin tweaking the WSDL to be simpler and more straightforward. Tweak, re-gen, repeat. You'll learn a lot this way, and it's portable knowledge.
• Stick to plain old language classes (POCO, POJO, etc.) for complex types. Do NOT use platform-specific constructs like List<> or DataTable. Even PHP associative arrays will appear to work but fail in ways that are difficult to debug across platforms.
• Stick to basic data types: bool, int, float, string, date(Time), and arrays. Odds are, the more particular you get about a data type, the less agile you'll be to new requirements over time. You do NOT want to change your WSDL if you can avoid it.
• One exception to the data types above - give yourself a NameValuePair mechanism of some kind. You wouldn't believe how many times a list of these things will save your bacon in terms of flexibility.
• Set a real namespace for your WSDL. It's not hard, but you might not believe how many web services I've seen in namespace "http://www.tempuri.org". Also, use a URN ("urn:com-myweb-servicename-v1", not a URL-based namespace ("http://servicename.myweb.com/v1". It's not a website, it's an abstract set of characters that defines a logical grouping. I've probably had a dozen people call me for support and say they went to the "website" and it didn't work.

    DecimalPosition = InStr(NumStr, ".")
    Numbers(0) = "Zero"
    If DecimalPosition > 0 And DecimalPosition < Len(NumStr) Then
        Temp1 = " point"
        For n = DecimalPosition + 1 To Len(NumStr)
            Temp1 = Temp1 & " " & Numbers(Val(Mid(NumStr, n, 1)))
        Next n
        WordNum = WordNum & Temp1
    End If
    If Len(WordNum) = 0 Or Left(WordNum, 2) = " p" Then
        WordNum = "Zero" & WordNum
    End If
End Function

Function GetTens(TensNum As Integer) As String
' Converts a number from 0 to 99 into text.
    If TensNum <= 19 Then
        GetTens = Numbers(TensNum)
    Else
        Dim MyNo As String
        MyNo = Format(TensNum, "00")
        GetTens = Tens(Val(Left(MyNo, 1))) & " " & Numbers(Val(Right(MyNo, 1)))
    End If
End Function

After this, From File Menu select Save Book ,from next menu select "Excel 97-2003 Add-In (*.xla)

It will save as Excel Add-In. that will be available till the Ms.Office Installation to that machine.

Now Open any Excel File in any Cell type =WordNum(<your numeric value or cell reference>)

you will see a Words equivalent of the numeric value.

• validate: validates the schema, no change happens to the database.
• update: updates the schema with current execute query.
• create: creates new schema every time, and destroys previous data.
• create-drop: drops the schema when the application is stopped or SessionFactory is closed explicitly.

DECLARE @LastChangeDate as date 
SET @LastChangeDate = GETDATE() 

I know that this is quite old thing, but I solved issue like that: I had parent and child element was scrollable.

   if ($('#parent > *').length == 0 ){
        var wait = setInterval(function() {
            if($('#parent > *').length != 0 ) {
                $('#parent .child').bind('scroll',function() {
                  //do staff
                });
                clearInterval(wait);
            },1000);
        }

The issue I had is that I didn't know when the child is loaded to DOM, but I kept checking for it every second.

NOTE:this is useful if it happens soon but not right after document load, otherwise it will use clients computing power for no reason.

One thing that really hung me up, was when I inspected this html in the browser, instead of seeing it expanded to something like:

<button ng-click="removeTask(1234)">remove</button>

I saw:

<button ng-click="removeTask(task.id)">remove</button>

However, the latter works!

This is because you are in the "Angular World", when inside ng-click="" Angular all ready knows about task.id as you are inside it's model. There is no need to use Data binding, as in {{}}.

Further, if you wanted to pass the task object itself, you can like:

<button ng-click="removeTask(task)">remove</button>

this worked for me:

jQuery('form').attr("placeholder","Wert eingeben");

but now this don't work:

// Prioritize "important" elements on medium.
            skel.on('+medium -medium', function() {
                jQuery.prioritize(
                    '.important\\28 medium\\29',
                    skel.breakpoint('medium').active
                );
            });

I had a similar issue and ended up with this:

For me this has the advantage that data and annotation are not overlapping.

from matplotlib import pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)

# annotations at the side (ordered by B values)
x0,x1=ax.get_xlim()
y0,y1=ax.get_ylim()
for ii, ind in enumerate(np.argsort(B)):
    x = A[ind]
    y = B[ind]
    xPos = x1 + .02 * (x1 - x0)
    yPos = y0 + ii * (y1 - y0)/(len(B) - 1)
    ax.annotate('',#label,
          xy=(x, y), xycoords='data',
          xytext=(xPos, yPos), textcoords='data',
          arrowprops=dict(
                          connectionstyle="arc3,rad=0.",
                          shrinkA=0, shrinkB=10,
                          arrowstyle= '-|>', ls= '-', linewidth=2
                          ),
          va='bottom', ha='left', zorder=19
          )
    ax.text(xPos + .01 * (x1 - x0), yPos,
            '({:.2f}, {:.2f})'.format(x,y),
            transform=ax.transData, va='center')

plt.grid()
plt.show()

Using the text argument in .annotate ended up with unfavorable text positions. Drawing lines between a legend and the data points is a mess, as the location of the legend is hard to address.

UCanAccess is a pure Java JDBC driver that allows us to read from and write to Access databases without using ODBC. It uses two other packages, Jackcess and HSQLDB, to perform these tasks. The following is a brief overview of how to get it set up.

Option 1: Using Maven

If your project uses Maven you can simply include UCanAccess via the following coordinates:

groupId: net.sf.ucanaccess
artifactId: ucanaccess

The following is an excerpt from pom.xml, you may need to update the <version> to get the most recent release:

  <dependencies>
    <dependency>
        <groupId>net.sf.ucanaccess</groupId>
        <artifactId>ucanaccess</artifactId>
        <version>4.0.4</version>
    </dependency>
  </dependencies>

Option 2: Manually adding the JARs to your project

As mentioned above, UCanAccess requires Jackcess and HSQLDB. Jackcess in turn has its own dependencies. So to use UCanAccess you will need to include the following components:

UCanAccess (ucanaccess-x.x.x.jar)
HSQLDB (hsqldb.jar, version 2.2.5 or newer)
Jackcess (jackcess-2.x.x.jar)
commons-lang (commons-lang-2.6.jar, or newer 2.x version)
commons-logging (commons-logging-1.1.1.jar, or newer 1.x version)

Fortunately, UCanAccess includes all of the required JAR files in its distribution file. When you unzip it you will see something like

ucanaccess-4.0.1.jar  
  /lib/
    commons-lang-2.6.jar  
    commons-logging-1.1.1.jar  
    hsqldb.jar  
    jackcess-2.1.6.jar

All you need to do is add all five (5) JARs to your project.

NOTE: Do not add loader/ucanload.jar to your build path if you are adding the other five (5) JAR files. The UcanloadDriver class is only used in special circumstances and requires a different setup. See the related answer here for details.

Eclipse: Right-click the project in Package Explorer and choose Build Path > Configure Build Path.... Click the "Add External JARs..." button to add each of the five (5) JARs. When you are finished your Java Build Path should look something like this

NetBeans: Expand the tree view for your project, right-click the "Libraries" folder and choose "Add JAR/Folder...", then browse to the JAR file.

After adding all five (5) JAR files the "Libraries" folder should look something like this:

IntelliJ IDEA: Choose File > Project Structure... from the main menu. In the "Libraries" pane click the "Add" (+) button and add the five (5) JAR files. Once that is done the project should look something like this:

That's it!

Now "U Can Access" data in .accdb and .mdb files using code like this

// assumes...
//     import java.sql.*;
Connection conn=DriverManager.getConnection(
        "jdbc:ucanaccess://C:/__tmp/test/zzz.accdb");
Statement s = conn.createStatement();
ResultSet rs = s.executeQuery("SELECT [LastName] FROM [Clients]");
while (rs.next()) {
    System.out.println(rs.getString(1));
}

Disclosure

At the time of writing this Q&A I had no involvement in or affiliation with the UCanAccess project; I just used it. I have since become a contributor to the project.

You're very close:

while IFS=$'\t' read -r -a myArray
do
 echo "${myArray[0]}"
 echo "${myArray[1]}"
 echo "${myArray[2]}"
done < myfile

(The -r tells read that \ isn't special in the input data; the -a myArray tells it to split the input-line into words and store the results in myArray; and the IFS=$'\t' tells it to use only tabs to split words, instead of the regular Bash default of also allowing spaces to split words as well. Note that this approach will treat one or more tabs as the delimiter, so if any field is blank, later fields will be "shifted" into earlier positions in the array. Is that O.K.?)

I git-rm'd a few files and went on making changes before my next commit when I realized I needed some of those files back. Rather than stash and reset, you can simply checkout the individual files you missed/removed if you want:

git checkout HEAD path/to/file path/to/another_file

This leaves your other uncommitted changes intact with no workarounds.

I am using this method in my application and it's working fine. I hope this may help you too.

func makeCall(phone: String) {
    let formatedNumber = phone.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet).joinWithSeparator("")
    let phoneUrl = "tel://\(formatedNumber)"
    let url:NSURL = NSURL(string: phoneUrl)!
    UIApplication.sharedApplication().openURL(url)
}

In my case I believe I had an old Ruby remaining on the system, not registered on rvm, and even if the path variables and gem list was okay, it would still use the old Ruby during deployments with Capistrano

And then I realized, the Ruby I had installed with rvm wasn't set to the default one. Running

rvm alias create default <rvm_registered_ruby>

Fixed it.

Define a style in UserControl.Resources or Window.Resources

 <Window.Resources>
        <Style x:Key="MyButton" TargetType="Button">
            <Setter Property="OverridesDefaultStyle" Value="True" />
            <Setter Property="Cursor" Value="Hand" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="Button">
                        <Border Name="border" BorderThickness="0" BorderBrush="Black" Background="{TemplateBinding Background}">
                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
                        </Border>
                        <ControlTemplate.Triggers>
                            <Trigger Property="IsMouseOver" Value="True">
                                <Setter Property="Opacity" Value="0.8" />
                            </Trigger>
                        </ControlTemplate.Triggers>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>

Then add the style to your button this way Style="{StaticResource MyButton}"

<Button Name="btnSecond" Width="350" Height="120" Margin="15" Style="{StaticResource MyButton}">
    <Button.Background>
        <ImageBrush ImageSource="/Remove_Default_Button_Effect;component/Images/WithStyle.jpg"></ImageBrush>
    </Button.Background>
</Button>

        for (...) {
            while (...) {
                if (...) {
                    break loop; // Exist the outermost do-while loop
                }
                if (...) {
                    continue; // skips current iteration in the while loop
                }
            }
        }
        if (...) {
            break loop;
        }
        if (...) {
            break loop;
        }
        if (...) {
            break loop;
        }
        if (...) {
            break loop;
        }
        ok = true;
        break;
    } while(true);
    CleanupAndCallbackBeforeReturning(ok);
    return ok;
};

With any $SHELL that supports it (dash/zsh/bash...):

find . -name "*.txt" -exec $SHELL -c '
    for i in "$@" ; do
        echo "$i"

Done.

my suggestion will be add a function call settings like this inside the function check the header which is appropriate for it. I am sure it will definitely work. it is perfectly working for me.

function getSettings(requestData) {
    return {
        url: requestData.url,
        dataType: requestData.dataType || "json",
        data: requestData.data || {},
        headers: requestData.headers || {
            "accept": "application/json; charset=utf-8",
            'Authorization': 'Bearer ' + requestData.token
        },
        async: requestData.async || "false",
        cache: requestData.cache || "false",
        success: requestData.success || {},
        error: requestData.error || {},
        complete: requestData.complete || {},
        fail: requestData.fail || {}
    };
}

then call your data like this

    var requestData = {
        url: 'API end point',
        data: Your Request Data,
        token: Your Token
    };

    var settings = getSettings(requestData);
    settings.method = "POST"; //("Your request type")
    return $http(settings);

to get value of textbox

   string username = TextBox1.Text;
   string password = TextBox2.Text;

to set value of textbox

  TextBox1.Text = "my_username";
   TextBox2.Text = "12345";

I have created a sorting function in Typescript which we can use to search strings, dates and numbers in array of objects. It can also sort on multiple fields.

export type SortType = 'string' | 'number' | 'date';
export type SortingOrder = 'asc' | 'desc';

export interface SortOptions {
  sortByKey: string;
  sortType?: SortType;
  sortingOrder?: SortingOrder;
}


class CustomSorting {
    static sortArrayOfObjects(fields: SortOptions[] = [{sortByKey: 'value', sortType: 'string', sortingOrder: 'desc'}]) {
        return (a, b) => fields
          .map((field) => {
            if (!a[field.sortByKey] || !b[field.sortByKey]) {
              return 0;
            }

            const direction = field.sortingOrder === 'asc' ? 1 : -1;

            let firstValue;
            let secondValue;

            if (field.sortType === 'string') {
              firstValue = a[field.sortByKey].toUpperCase();
              secondValue = b[field.sortByKey].toUpperCase();
            } else if (field.sortType === 'number') {
              firstValue = parseInt(a[field.sortByKey], 10);
              secondValue = parseInt(b[field.sortByKey], 10);
            } else if (field.sortType === 'date') {
              firstValue = new Date(a[field.sortByKey]);
              secondValue = new Date(b[field.sortByKey]);
            }
            return firstValue > secondValue ? direction : firstValue < secondValue ? -(direction) : 0;

          })
          .reduce((pos, neg) => pos ? pos : neg, 0);
      }
    }
}

Usage:

const sortOptions = [{
      sortByKey: 'anyKey',
      sortType: 'string',
      sortingOrder: 'asc',
    }];

arrayOfObjects.sort(CustomSorting.sortArrayOfObjects(sortOptions));

Here is the corresponding presentViewController version that I used if it helps other newbies like myself:

if ([self respondsToSelector:@selector(presentModalViewController:animated:)]) {
    [self performSelector:@selector(presentModalViewController:animated:) withObject:testView afterDelay:0];
} else {
    [self presentViewController:configView animated:YES completion:nil];
}
[testView.testFrame setImage:info]; //this doesn't work for performSelector
[testView.testText setHidden:YES];

I had used a ViewController 'generically' and was able to get the modal View to appear differently depending what it was called to do (using setHidden and setImage). and things were working nicely before, but performSelector ignores 'set' stuff, so in the end it seems to be a poor solution if you try to be efficient like I tried to be...

to select records for the last 7 days

WHERE Created_Date >= DATEADD(day, -7, GETDATE())

to select records for the current week

SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT * FROM
WHERE CreatedDate >= DATEADD(day, 1 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE())) 
  AND CreatedDate <  DATEADD(day, 8 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))

if you want to select records for last week instead of the last 7 days

SET DATEFIRST 1 -- Define beginning of week as Monday
SELECT * FROM  
WHERE CreatedDate >= DATEADD(day, -(DATEPART(dw, GETDATE()) + 6), CONVERT(DATE, GETDATE())) 
  AND CreatedDate <  DATEADD(day, 1 - DATEPART(dw, GETDATE()), CONVERT(DATE, GETDATE()))

var temp = data.oldKey; // or data['oldKey']
data.newKey = temp;
delete data.oldKey;

$this->db->where('(a = 1 or a = 2)');

If you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()
        @RenderSection("scripts", required: false)
    </body>
</html>

then you can have an index.cshtml content view like this

@section scripts {
     <script type="text/javascript">alert('hello');</script>
}

the required indicates whether or not the view using the layout page must have a scripts section

Change your javascript to:

var input = document.getElementById('userInput').value;

This will get the value that has been types into the text box, not a DOM object

there is a simple way to do this: in the html file add:

<link rel="stylesheet" href="fonts/vermin_vibes.ttf" />

Note: you put the name of .ttf file you have. then go to to your css file and add:

h1 {
    color: blue;
    font-family: vermin vibes;
}

Note: you put the font family name of the font you have.

Note: do not write the font-family name as your font.ttf name example: if your font.ttf name is: "vermin_vibes.ttf" your font-family will be: "vermin vibes" font family doesn't contain special chars as "-,_"...etc it only can contain spaces.

You can use concatenation operator and instead of declaring two variables only use one variable

String finalString =  cursor.getString(numcol) + cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE));

I am answering this old question just because it still shows up in google queries and I think one optimal answer is missing. Try this code: use ::before or ::after

See Align <hr> to the left in an HTML5-compliant way

Check for the import statements.It should be ended with semicolon. If you miss any, you will get this error.

Also check whether following import statement added in you component.

import { threadId } from 'worker_threads';

If so remove that line. It works for me.

I would also like to point out that you can use a javascript approach, window.history.replaceState to prevent a resubmit on refresh and back button.

<script>
    if ( window.history.replaceState ) {
        window.history.replaceState( null, null, window.location.href );
    }
</script>

Proof of concept here: https://dtbaker.net/files/prevent-post-resubmit.php

I would still recommend a Post/Redirect/Get approach, but this is a novel JS solution.

In Python 2 use the tkFileDialog module.

import tkFileDialog

tkFileDialog.askopenfilename()

In Python 3 use the tkinter.filedialog module.

import tkinter.filedialog

tkinter.filedialog.askopenfilename()

array_values() will do pretty much what you want:

$numeric_indexed_array = array_values($your_array);
// $numeric_indexed_array = array('bar', 'bin', 'ipsum');
print($numeric_indexed_array[0]); // bar

WORKER TIMEOUT means your application cannot response to the request in a defined amount of time. You can set this using gunicorn timeout settings. Some application need more time to response than another.

Another thing that may affect this is choosing the worker type

The default synchronous workers assume that your application is resource-bound in terms of CPU and network bandwidth. Generally this means that your application shouldn’t do anything that takes an undefined amount of time. An example of something that takes an undefined amount of time is a request to the internet. At some point the external network will fail in such a way that clients will pile up on your servers. So, in this sense, any web application which makes outgoing requests to APIs will benefit from an asynchronous worker.

When I got the same problem as yours (I was trying to deploy my application using Docker Swarm), I've tried to increase the timeout and using another type of worker class. But all failed.

And then I suddenly realised I was limitting my resource too low for the service inside my compose file. This is the thing slowed down the application in my case

deploy:
  replicas: 5
  resources:
    limits:
      cpus: "0.1"
      memory: 50M
  restart_policy:
    condition: on-failure

So I suggest you to check what thing slowing down your application in the first place

A function like that without validating the enum is a trifle dangerous. I suggest using a switch statement. Another advantage is that this can be used for enums that have defined values, for example for flags where the values are 1,2,4,8,16 etc.

Also put all your enum strings together in one array:-

static const char * allEnums[] = {
    "Undefined",
    "apple",
    "orange"
    /* etc */
};

define the indices in a header file:-

#define ID_undefined       0
#define ID_fruit_apple     1
#define ID_fruit_orange    2
/* etc */

Doing this makes it easier to produce different versions, for example if you want to make international versions of your program with other languages.

Using a macro, also in the header file:-

#define CASE(type,val) case val: index = ID_##type##_##val; break;

Make a function with a switch statement, this should return a const char * because the strings static consts:-

const char * FruitString(enum fruit e){

    unsigned int index;

    switch(e){
        CASE(fruit, apple)
        CASE(fruit, orange)
        CASE(fruit, banana)
        /* etc */
        default: index = ID_undefined;
    }
    return allEnums[index];
}

If programming with Windows then the ID_ values can be resource values.

(If using C++ then all the functions can have the same name.

string EnumToString(fruit e);

)

Yes, It is required to add libraries after the source files/objects files. This command will solve the problem:

gcc -static -L/usr/lib -I/usr/lib main.c -ltommath

You can use _.mapValues(users, function(o) { return o.age; }); in Lodash and _.mapObject({ one: 1, two: 2, three: 3 }, function (v) { return v * 3; }); in Underscore.

I had the same issue and I resolved it with MySQL workbench, as shown in the attached screenshot:

1. in the navigator (on the left side), under the section "management", click on "Status and System variables",
2. then choose "system variables" (tab at the top),
3. then search for "connection" in the search field,
4. and 5. you will see two fields that need to be adjusted to fit your needs (max_connections and mysqlx_max_connections).

Hope that helps!

The system does not allow me to upload pictures, instead please click on this link and you can see my screenshot...

Color? color = null;

or you can use

Color? color = new Color?();

example where assigning null wont work

color = x == 5 ? Color.Red : x == 9 ? Color.Black : null ; 

so you can use :

 color = x == 5 ? Color.Red : x == 9 ? Color.Black : new Color?(); 

RFC 2616, section 14.9.1:

Indicates that all or part of the response message is intended for a single user and MUST NOT be cached by a shared cache...A private (non-shared) cache MAY cache the response.

Browsers could use this information. Of course, the current "user" may mean many things: OS user, a browser user (e.g. Chrome's profiles), etc. It's not specified.

For me, a more concrete example of Cache-Control: private is that proxy servers (which typically have many users) won't cache it. It is meant for the end user, and no one else.

FYI, the RFC makes clear that this does not provide security. It is about showing the correct content, not securing content.

This usage of the word private only controls where the response may be cached, and cannot ensure the privacy of the message content.

For some reason Louise's answer didn't work for me I had to:

-Open anaconda prompt and generate the config file for Jupyter: jupyter notebook --generate-config

-Open the newly created config file at: C:\Users\builder\.juptyer\jupyter_notebook_config.py

-Add the following to the file:

import webbrowser
webbrowser.register('chrome', None, webbrowser.GenericBrowser(r'C:\Program Files (x86)\Google\Chrome\Application\chrome.exe'))
c.NotebookApp.browser = 'chrome'

The only time you would NOT throw exceptions from constructors is if your project has a rule against using exceptions (for instance, Google doesn't like exceptions). In that case, you wouldn't want to use exceptions in your constructor any more than anywhere else, and you'd have to have an init method of some sort instead.

To add a bit on to @ethanmay 's answer: (https://stackoverflow.com/a/44334424/8479303)...

If there are contents within the div that has the curved corners, you have to set overflow: hidden because otherwise the child div's overflow can give the impression that the border-radius isn't working.

<!-- This will look like the border-radius isn't working-->
<div style="border: 1px solid black; border-radius: 10px;">
  <div style="background: red;">
      text!
  </div>
</div>

<!-- but here the contents properly fit within the rounded div -->
<div style="border: 1px solid black; border-radius: 10px; overflow: hidden;">
  <div style="background: red;">
      text!
  </div>
</div>

Package graphql-type-json supports custom-scalars type JSON. Use it can show all the field of your json objects. Here is the link of the example in ApolloGraphql Server. https://www.apollographql.com/docs/apollo-server/schema/scalars-enums/#custom-scalars

Just in case you were not able to accomplish the above code, here is a simple way of using it with jquery:

$.getJSON("http://www.geoplugin.net/json.gp?jsoncallback=?",

            document.write('data["i"] = ' + i + '<br/>');

There is quite a mix of direct and indirect answers on this page and some good advice in comments, but there isn't an answer that represents what I would write in my own project.

PHP Escape Sequence \R documentation: https://www.php.net/manual/en/regexp.reference.escape.php#:~:text=line%20break,\r\n

Code: (Demo)

$string = '
My text1

My text2


My text3


';

var_export(
    preg_split('/\R+/', $string, 0, PREG_SPLIT_NO_EMPTY)
);

Output:

array (
  0 => 'My text1',
  1 => 'My text2',
  2 => 'My text3',
)

The OP makes no mention of trimming horizontal whitespace characters from the lines, so there is no expectation of removing \s or \h while exploding on variable (system agnostic) new lines.

While PHP_EOL is sensible advice, it lacks the flexibility appropriately explode the string when the newline sequence is coming from another operating system.

Using a non-regex explode will tend to be less direct because it will require string preparations. Furthermore, there may be mopping up after the the explosions if there are unwanted blank lines to remove.

Using \R+ (one or more consecutive newline sequences) and the PREG_SPLIT_NO_EMPTY function flag will deliver a gap-less, indexed array in a single, concise function call. Some people have a bias against regular expressions, but this is a perfect case for why regex should be used. If performance is a concern for valid reasons (e.g. you are processing hundreds of thousands of points of data), then go ahead and invest in benchmarking and micro-optimization. Beyond that, just use this one-line of code so that your code is brief, robust, and direct.

So long as Excel can open the file, the functionality to change the format of the opened file is built in.

To convert an .html file, open it using Excel (File - Open) and then save it as a .xlsx file from Excel (File - Save as).

To do it using VBA, the code would look like this:

Sub Open_HTML_Save_XLSX()

    Workbooks.Open Filename:="C:\Temp\Example.html"
    ActiveWorkbook.SaveAs Filename:= _
        "C:\Temp\Example.xlsx", FileFormat:= _
        xlOpenXMLWorkbook

End Sub

I just got this exact error in .Net Core 2.2 Entity Framework because I didn't have the set; in my DbContext like so:

public DbSet<Account> Account { get; }

changed to:

public DbSet<Account> Account { get; set;}

However, it didn't show the exception until I tried to use a linq query with Where() and Select() as others had mentioned above.

I was trying to set the DbSet as read only. I'll keep trying...

Wouldn't establishing a connection to the database do this for you? If the database isn't up you won't be able to establish a connection.

Could you try this one:

create or replace 
procedure point_triangle
IS
BEGIN
  FOR thisteam in (select P.FIRSTNAME,P.LASTNAME, SUM(P.PTS) S from PLAYERREGULARSEASON P  where P.TEAM = 'IND'  group by P.FIRSTNAME, P.LASTNAME order by SUM(P.PTS) DESC)
  LOOP
    dbms_output.put_line(thisteam.FIRSTNAME|| ' ' || thisteam.LASTNAME  || ':' || thisteam.S);
  END LOOP;

END;

dot -Tps input.dot > output.eps
dot -Tpng input.dot > output.png

PostScript output seems always there. I am not sure if dot has PNG output by default. This may depend on how you have built it.

You can use the Y-combinator: (Wikipedia)

// ES5 syntax
var Y = function Y(a) {
  return (function (a) {
    return a(a);
  })(function (b) {
    return a(function (a) {
      return b(b)(a);
    });
  });
};

// ES6 syntax
const Y = a=>(a=>a(a))(b=>a(a=>b(b)(a)));

// If the function accepts more than one parameter:
const Y = a=>(a=>a(a))(b=>a((...a)=>b(b)(...a)));

And you can use it as this:

// ES5
var fn = Y(function(fn) {
  return function(counter) {
    console.log(counter);
    if (counter > 0) {
      fn(counter - 1);
    }
  }
});

// ES6
const fn = Y(fn => counter => {
  console.log(counter);
  if (counter > 0) {
    fn(counter - 1);
  }
});

You can do it using pandas only:

In [235]:
dfTest = pd.DataFrame({'A':[14.00,90.20,90.95,96.27,91.21],'B':[103.02,107.26,110.35,114.23,114.68], 'C':['big','small','big','small','small']})
df = dfTest[['A', 'B']]
df_norm = (df - df.min()) / (df.max() - df.min())
print df_norm
print pd.concat((df_norm, dfTest.C),1)

          A         B
0  0.000000  0.000000
1  0.926219  0.363636
2  0.935335  0.628645
3  1.000000  0.961407
4  0.938495  1.000000
          A         B      C

1  0.926219  0.363636  small

I think .myi you can repair from inside mysql.

If you see these type of error messages from MySQL: Database failed to execute query (query) 1016: Can't open file: 'sometable.MYI'. (errno: 145) Error Msg: 1034: Incorrect key file for table: 'sometable'. Try to repair it thenb you probably have a crashed or corrupt table.

You can check and repair the table from a mysql prompt like this:

check table sometable;
+------------------+-------+----------+----------------------------+
| Table | Op | Msg_type | Msg_text | 
+------------------+-------+----------+----------------------------+ 
| yourdb.sometable | check | warning | Table is marked as crashed | 
| yourdb.sometable | check | status | OK | 
+------------------+-------+----------+----------------------------+ 

repair table sometable;
+------------------+--------+----------+----------+ 
| Table | Op | Msg_type | Msg_text | 
+------------------+--------+----------+----------+ 
| yourdb.sometable | repair | status | OK | 
+------------------+--------+----------+----------+

and now your table should be fine:

check table sometable;
+------------------+-------+----------+----------+ 
| Table | Op | Msg_type | Msg_text |
+------------------+-------+----------+----------+ 
| yourdb.sometable | check | status | OK |
+------------------+-------+----------+----------+

It is not clear to me what you mean by "escape an executable which is running", but ctrl-z will put a process into the background and return control to the command line. You can then use the fg command to bring the program back into the foreground.

using Calendar is simple:

Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("Europe/Madrid"));
Date currentDate = calendar.getTime();

[checked 27 Nov 2020 and confirmed to be still accurate with Xcode 12.1]

The most convenient way these days: Xcode provides a code snippet to do this where you just have to enter the delay value and the code you wish to run after the delay.

1. click on the + button at the top right of Xcode.
2. search for after
3. It will return only 1 search result, which is the desired snippet (see screenshot). Double click it and you're good to go.

There are a couple options you can use:

1. You could try using the string "(DATETIME('now'))" instead.
2. Insert the datetime yourself, ie with System.currentTimeMillis()
3. When creating the SQLite table, specify a default value for the created_date column as the current date time.
4. Use SQLiteDatabase.execSQL to insert directly.

Of course @Stephan202 has given a really nice answer. I am providing an alternative.

def compressx(min_index = 3, max_index = 6, x = ['a', 'b', 'c', 'd', 'e', 'f', 'g']):
    x = x[:min_index] + [''.join(x[min_index:max_index])] + x[max_index:]
    return x
compressx()

>>>['a', 'b', 'c', 'def', 'g']

You can also do the following.

x = x[:min_index] + [''.join(x[min_index:max_index])] + x[max_index:]
print(x)

>>>['a', 'b', 'c', 'def', 'g']

GroupBox is better.But not only group box, even you can use Panels (System.Windows.Forms.Panel).

• That is very usefully when you are designing Internet Protocol version 4 setting dialog.(Check it with your pc(windows),then you can understand the behavior)

You can use routerLink which is an alternative of href for angular 2.** Use routerLink as below in html

<a routerLink="/dashboard">My Link</a>

and make sure you register your routerLink in modules.ts or router.ts like this

const routes: Routes = [
  { path: 'dashboard', component: DashboardComponent }
]

_msize(array) in Windows or malloc_usable_size(array) in Linux should work for the dynamic array

Both are located within malloc.h and both return a size_t

Gutch's code is close, but it'll only work right if:

• There are no annotations (links, fields, etc), no Document Structure/Marked Content, no bookmarks, no document-level script, etc, etc, etc...
• The page size happens to be A.4 (decent odds, but it won't work on any ol' PDF you happen to come across)
• You don't mind losing all the original document metadata (producer, creation date, possibly author/title/keywords), and maybe the document ID. You can't copy the creation date and doc ID unless you do some pretty deep hackery on iText itself).

The Approved Method is to do it the other way around. Open the existing document with a PdfStamper, and use the returned PdfContentByte from getOverContent() to write text (and whatever else you might need) directly to the page. No second document needed.

And you can use a ColumnText to handle layout and such for you... no need to get down and dirty with beginText(),setFontAndSize(),drawText(),drawText()...,endText().

Here's a question and answer for this: Difference between screen.availHeight and window.height()

Has pics too, so you can actually see the differences. Hope this helps.

Basically, $(window).height() give you the maximum height inside of the browser window (viewport), and$(document).height() gives you the height of the document inside of the browser. Most of the time, they will be exactly the same, even with scrollbars.

What if you've got array of fieldsets?

<fieldset>
<input type="text" name="item[1]" />
<input type="text" name="item[2]" />
<input type="hidden" name="fset[]"/>
</fieldset>

<fieldset>
<input type="text" name="item[3]" />
<input type="text" name="item[4]" />
<input type="hidden" name="fset[]"/>
</fieldset>

I added a hidden field to count the number of the fieldsets. The user can add or delete the fields and then save it.

Use the below command to solve your issue,

Your server side code is JAVA then Follow this below steps

step 1 : Download urlrewritefilter JAR Click Here and save to build path WEB-INF/lib

step 2 : Enable HTML5 Mode $locationProvider.html5Mode(true);

step 3 : set base URL <base href="/example.com/"/>

step 4 : copy and paste to your WEB.XML

 <filter>
     <filter-name>UrlRewriteFilter</filter-name>
 <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>UrlRewriteFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

step 5 : create file in WEN-INF/urlrewrite.xml

 <urlrewrite default-match-type="wildcard">


    <rule>
            <from>/</from>
            <to>/index.html</to>
        </rule>

    <!--Write every state dependent on your project url-->
    <rule>
            <from>/example</from>
            <to>/index.html</to>
        </rule>
    </urlrewrite>

You could try this solution :

In your location block when you use proxy_pass do something like this:

location ... {

  add_header yourHeaderName yourValue;
  proxy_pass xxxx://xxx_my_proxy_addr_xxx;

  # Now use this solution:
  proxy_ignore_headers yourHeaderName // but set by proxy

  # Or if above didn't work maybe this:
  proxy_hide_header yourHeaderName // but set by proxy

}

I'm not sure would it be exactly what you need but try some manipulation of this method and maybe result will fit your problem.

Also you can use this combination:

proxy_hide_header headerSetByProxy;
set $sent_http_header_set_by_proxy yourValue;

var query = list.Where(r => listofIds.Any(id => id == r.Id));

Another approach, useful if the listOfIds array is large:

HashSet<int> hash = new HashSet<int>(listofIds);
var query = list.Where(r => hash.Contains(r.Id));

One very quick way around this is, when you're viewing the "Your connection is not private" screen:

type badidea

type thisisunsafe (credit to The Java Guy for finding the new passphrase)

That will allow the security exception when Chrome is otherwise not allowing the exception to be set via clickthrough, e.g. for this HSTS case.

This is only recommended for local connections and local-network virtual machines, obviously, but it has the advantage of working for VMs being used for development (e.g. on port-forwarded local connections) and not just direct localhost connections.

Note: the Chrome developers have changed this passphrase in the past, and may do so again. If badidea ceases to work, please leave a note here if you learn the new passphrase. I'll try to do the same.

Edit: as of 30 Jan 2018 this passphrase appears to no longer work.

If I can hunt down a new one I'll post it here. In the meantime I'm going to take the time to set up a self-signed certificate using the method outlined in this stackoverflow post:

How to create a self-signed certificate with openssl?

Edit: as of 1 Mar 2018 and Chrome Version 64.0.3282.186 this passphrase works again for HSTS-related blocks on .dev sites.

Edit: as of 9 Mar 2018 and Chrome Version 65.0.3325.146 the badidea passphrase no longer works.

Edit 2: the trouble with self-signed certificates seems to be that, with security standards tightening across the board these days, they cause their own errors to be thrown (nginx, for example, refuses to load an SSL/TLS cert that includes a self-signed cert in the chain of authority, by default).

The solution I'm going with now is to swap out the top-level domain on all my .app and .dev development sites with .test or .localhost. Chrome and Safari will no longer accept insecure connections to standard top-level domains (including .app).

The current list of standard top-level domains can be found in this Wikipedia article, including special-use domains:

Wikipedia: List of Internet Top Level Domains: Special Use Domains

These top-level domains seem to be exempt from the new https-only restrictions:

• .local
• .localhost
• .test
• (any custom/non-standard top-level domain)

Use Xcode's native Color Literals feature to add hex colors easily and natively.

Type Color Literal into your code and let Xcode autocomplete do the rest.

The color picker UI will allow you to paste in a Hex Color: #FF9300

The git diff of the macro will show RGB values rather than hex:

let orange = #colorLiteral(red: 1, green: 0.5763723254, blue: 0, alpha: 1)

But it's still an easy way to paste in hex without any 3rd party tools or extensions.

I would do it like this:

var form2 = new Form2();
form2.Show();

and to close current form I would use

this.Hide(); instead of

this.close();

You know, all this stuff about the joins and the 'complex transactions' -- but it was Monty himself who, many years ago, explained away the "need" for COMMIT / ROLLBACK, saying that 'all that is done in the logic classes (and not the database) anyway' -- so it's the same thing all over again. What is needed is a dumb yet incredibly tidy and fast data storage/retrieval engine, for 99% of what the web apps do.

My understanding is that this question is better answered over in this post.

But briefly, the answer to the OP with this method is simply:

s1 = pd.merge(df1, df2, how='inner', on=['user_id'])

Which gives s1 with 5 columns: user_id and the other two columns from each of df1 and df2.

>>> a = "545.2222"
>>> float(a)
545.22220000000004
>>> int(float(a))
545

You can use inWaiting() to get the amount of bytes available at the input queue.

Then you can use read() to read the bytes, something like that:

While True:
    bytesToRead = ser.inWaiting()
    ser.read(bytesToRead)

Why not to use readline() at this case from Docs:

Read a line which is terminated with end-of-line (eol) character (\n by default) or until timeout.

You are waiting for the timeout at each reading since it waits for eol. the serial input Q remains the same it just a lot of time to get to the "end" of the buffer, To understand it better: you are writing to the input Q like a race car, and reading like an old car :)

Needed the form elements named in the HTML as an array to be an array in the javascript object, as if the form was actually submitted.

If there is a form with multiple checkboxes such as:

<input name='breath[0]' type='checkbox' value='presence0'/>
<input name='breath[1]' type='checkbox' value='presence1'/>
<input name='breath[2]' type='checkbox' value='presence2'/>
<input name='serenity'  type='text' value='Is within the breath.'/>
...

The result is an object with:

data = {
   'breath':['presence0','presence1','presence2'],
   'serenity':'Is within the breath.'
}


var $form = $(this),
    data  = {};

$form.find("input").map(function()
{
    var $el  = $(this),
        name = $el.attr("name");

    if (/radio|checkbox/i.test($el.attr('type')) && !$el.prop('checked'))return;

    if(name.indexOf('[') > -1)
    {
        var name_ar = name.split(']').join('').split('['),
            name    = name_ar[0],
            index   = name_ar[1];

        data[name]  = data[name] || [];
        data[name][index] = $el.val();
    }
    else data[name] = $el.val();
});

And there are tons of answers here which helped improve my code, but they were either too complex or didn't do exactly want I wanted: Convert form data to JavaScript object with jQuery

Works but can be improved: only works on one-dimensional arrays and the resulting indexes may not be sequential. The length property of an array returns the next index number as the length of the array, not the actually length.

Hope this helped. Namaste!

I used numpy library and it works fine for me. Its just a single line and easy to understand. The input needs to be in a single size separated by space and the reshape converts the list into shape you want. Here (2,2) resizes the list of 4 elements into 2*2 matrix. Be careful in giving equal number of elements in the input corresponding to the dimension of the matrix.

import numpy as np
a=np.array(list(map(int,input().strip().split(' ')))).reshape(2,2)

print(a)

Input

array([[1, 2],
       [3, 4]])

you can try using JSONP . If the API is not supporting jsonp, you have to create a service which acts as a middleman between the API and your client. In my case, i have created a asmx service.

sample below:

ajax call:

$(document).ready(function () {
        $.ajax({
            crossDomain: true,
            type:"GET",
            contentType: "application/json; charset=utf-8",
            async:false,
            url: "<your middle man service url here>/GetQuote?callback=?",
            data: { symbol: 'ctsh' },
            dataType: "jsonp",                
            jsonpCallback: 'fnsuccesscallback'
        });
    });

service (asmx) which will return jsonp:

[WebMethod]
    [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
    public void GetQuote(String symbol,string callback)
    {          

        WebProxy myProxy = new WebProxy("<proxy url here>", true);

        myProxy.Credentials = new System.Net.NetworkCredential("username", "password", "domain");
        StockQuoteProxy.StockQuote SQ = new StockQuoteProxy.StockQuote();
        SQ.Proxy = myProxy;
        String result = SQ.GetQuote(symbol);
        StringBuilder sb = new StringBuilder();
        JavaScriptSerializer js = new JavaScriptSerializer();
        sb.Append(callback + "(");
        sb.Append(js.Serialize(result));
        sb.Append(");");
        Context.Response.Clear();
        Context.Response.ContentType = "application/json";
        Context.Response.Write(sb.ToString());
        Context.Response.End();         
    }

After much digging around we were able to scrape the info more or less (mainly from Keycloak's own JS client lib):

• Authorization Endpoint: /auth/realms/{realm}/tokens/login
• Token Endpoint: /auth/realms/{realm}/tokens/access/codes

As for OpenID Connect UserInfo, right now (1.1.0.Final) Keycloak doesn't implement this endpoint, so it is not fully OpenID Connect compliant. However, there is already a patch that adds that as of this writing should be included in 1.2.x.

But - Ironically Keycloak does send back an id_token in together with the access token. Both the id_token and the access_token are signed JWTs, and the keys of the token are OpenID Connect's keys, i.e:

"iss":  "{realm}"
"sub":  "5bf30443-0cf7-4d31-b204-efd11a432659"
"name": "Amir Abiri"
"email: "..."

So while Keycloak 1.1.x is not fully OpenID Connect compliant, it does "speak" in OpenID Connect language.

Turn it around by doing:

<style type="text/css">
  #middlecol {
    border-right: 2px solid red;
    width: 45%;
  }

  #middlecol table {
    max-width: 400px;
    width: 100% !important;
  }
</style>

Also I would advise you to:

• Not use the center tag (it's deprecated)
• Don't use width, bgcolor attributes, set them by CSS (width and background-color)

(assuming that you can control the table that was rendered)

As this adapter destroys the fragment when it is not visible to the user and only savedInstanceState of the fragment is kept for further use. This way a low amount of memory is used and a better performance is delivered in case of dynamic fragments.

That's why it's not working because you code something that is not right, that's why it always exit and the script executer will read it as not operable batch file that prevent it to exit and stop so it must be

tasklist /fi "IMAGENAME eq Notepad.exe" 2>NUL | find /I /N "Notepad.exe">NUL
if "%ERRORLEVEL%"=="0" (
msg * Program is running
goto Exit
)
else if "%ERRORLEVEL%"=="1" (
msg * Program is not running
goto Exit
)

rather than

@echo off
tasklist /fi "imagename eq notepad.exe" > nul
if errorlevel 1 taskkill /f /im "notepad.exe"
exit

$("#drop").change(function () {

});

You seem to be doing file name comparisons, so I would just add that OrdinalIgnoreCase is closest to what NTFS does (it's not exactly the same, but it's closer than InvariantCultureIgnoreCase)

If you prefer shorter if else statement, you can use this shorthand:

<%= typeof(id)!== 'undefined' ?  id : '' %>

It means display the id if is valid and blank if it wasn't.

When Python2.x sees a == b, it tries the following.

• If type(b) is a new-style class, and type(b) is a subclass of type(a), and type(b) has overridden __eq__, then the result is b.__eq__(a).
• If type(a) has overridden __eq__ (that is, type(a).__eq__ isn't object.__eq__), then the result is a.__eq__(b).
• If type(b) has overridden __eq__, then the result is b.__eq__(a).
• If none of the above are the case, Python repeats the process looking for __cmp__. If it exists, the objects are equal iff it returns zero.
• As a final fallback, Python calls object.__eq__(a, b), which is True iff a and b are the same object.

If any of the special methods return NotImplemented, Python acts as though the method didn't exist.

Note that last step carefully: if neither a nor b overloads ==, then a == b is the same as a is b.

The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS

for single line comment add # at starting of a line
for multiple line comments add ' (single quote) from where you want to start & add ' (again single quote) at the point where you want to end the comment line.

Either declare set1 and set2 as floats instead of integers or cast them to floats as part of the calculation:

SET @weight= CAST(@set1 AS float) / CAST(@set2 AS float);

Cause: A trigger was attempted to be retrieved for execution and was found to be invalid. This also means that compilation/authorization failed for the trigger.

Action: Options are to resolve the compilation/authorization errors, disable the trigger, or drop the trigger.

Syntax

ALTER TRIGGER trigger Name DISABLE;

ALTER TRIGGER trigger_Name ENABLE;

If you will be doing many searches of the array, AND matching always is defined as string equivalence, then you can normalize your data and use a hash.

my @strings = qw( aAa Bbb cCC DDD eee );

my %string_lut;

# Init via slice:
@string_lut{ map uc, @strings } = ();

# or use a for loop:
#    for my $string ( @strings ) {
#        $string_lut{ uc($string) } = undef;
#    }


#Look for a string:

my $search = 'AAa';

print "'$string' ", 
    ( exists $string_lut{ uc $string ? "IS" : "is NOT" ),
    " in the array\n";

Let me emphasize that doing a hash lookup is good if you are planning on doing many lookups on the array. Also, it will only work if matching means that $foo eq $bar, or other requirements that can be met through normalization (like case insensitivity).

Late to the party, but...

The environment I work in is highly constrained, supporting some vendor products and providing "value-added" services like reporting. Due to policy and contract limitations, I am not usually allowed the luxury of separate table/data space and/or the ability to create permanent code [it gets a little better, depending upon the application].

IOW, I can't usually develop a stored procedure or UDFs or temp tables, etc. I pretty much have to do everything through MY application interface (Crystal Reports - add/link tables, set where clauses from w/in CR, etc.). One SMALL saving grace is that Crystal allows me to use COMMANDS (as well as SQL Expressions). Some things that aren't efficient through the regular add/link tables capability can be done by defining a SQL Command. I use CTEs through that and have gotten very good results "remotely". CTEs also help w/ report maintenance, not requiring that code be developed, handed to a DBA to compile, encrypt, transfer, install, and then require multiple-level testing. I can do CTEs through the local interface.

The down side of using CTEs w/ CR is, each report is separate. Each CTE must be maintained for each report. Where I can do SPs and UDFs, I can develop something that can be used by multiple reports, requiring only linking to the SP and passing parameters as if you were working on a regular table. CR is not really good at handling parameters into SQL Commands, so that aspect of the CR/CTE aspect can be lacking. In those cases, I usually try to define the CTE to return enough data (but not ALL data), and then use the record selection capabilities in CR to slice and dice that.

So... my vote is for CTEs (until I get my data space).

Another way:

x=$'Some\nstring'
readarray -t y <<<"$x"

Or, if you don't have bash 4, the bash 3.2 equivalent:

IFS=$'\n' read -rd '' -a y <<<"$x"

You can also do it the way you were initially trying to use:

y=(${x//$'\n'/ })

This, however, will not function correctly if your string already contains spaces, such as 'line 1\nline 2'. To make it work, you need to restrict the word separator before parsing it:

IFS=$'\n' y=(${x//$'\n'/ })

...and then, since you are changing the separator, you don't need to convert the \n to space anymore, so you can simplify it to:

IFS=$'\n' y=($x)

This approach will function unless $x contains a matching globbing pattern (such as "*") - in which case it will be replaced by the matched file name(s). The read/readarray methods require newer bash versions, but work in all cases.

Evidence for truncation mentioned by others, (a personal example)

foo=$(ps -p 689 -o command); echo "$foo"

COMMAND
/opt/conda/bin/python -m ipykernel_launcher -f /root/.local/share/jupyter/runtime/kernel-5732db1a-d484-4a58-9d67-de6ef5ac721b.json

That ^^ captures that long output in a variable As opposed to

ps -p 689 -o command

COMMAND
/opt/conda/bin/python -m ipykernel_launcher -f /root/.local/share/jupyter/runtim

Since I was trying this from a Docker jupyter notebook, I needed to run this with the bang of course ..

!foo=$(ps -p 689 -o command); echo "$foo"

Surprisingly jupyter notebooks let you execute even that! But glad to help find the offending notebook taking up all my memory =D

try adding my answers (my thought of learning) :

__enter__ and [__exit__] both are methods that are invoked on entry to and exit from the body of "the with statement" (PEP 343) and implementation of both is called context manager.

the with statement is intend to hiding flow control of try finally clause and make the code inscrutable.

the syntax of the with statement is :

with EXPR as VAR:
    BLOCK

which translate to (as mention in PEP 343) :

mgr = (EXPR)
exit = type(mgr).__exit__  # Not calling it yet
value = type(mgr).__enter__(mgr)
exc = True
try:
    try:
        VAR = value  # Only if "as VAR" is present
        BLOCK
    except:
        # The exceptional case is handled here
        exc = False
        if not exit(mgr, *sys.exc_info()):
            raise
        # The exception is swallowed if exit() returns true
finally:
    # The normal and non-local-goto cases are handled here
    if exc:
        exit(mgr, None, None, None)

try some code:

the result of the server side same as before

sorry for my bad english and my unclear explanations, thank you....

Not exactly. You can't get two Streams out of one; this doesn't make sense -- how would you iterate over one without needing to generate the other at the same time? A stream can only be operated over once.

However, if you want to dump them into a list or something, you could do

stream.forEach((x) -> ((x == 0) ? heads : tails).add(x));

I found this SQL statement to be a useful place to start (sorry I can't attribute this to the original author; I found it somewhere on the internet):

SELECT * FROM
(SELECT
    sql_fulltext,
    sql_id,
    elapsed_time,
    child_number,
    disk_reads,
    executions,
    first_load_time,
    last_load_time
FROM    v$sql
ORDER BY elapsed_time DESC)
WHERE ROWNUM < 10
/

This finds the top SQL statements that are currently stored in the SQL cache ordered by elapsed time. Statements will disappear from the cache over time, so it might be no good trying to diagnose last night's batch job when you roll into work at midday.

You can also try ordering by disk_reads and executions. Executions is useful because some poor applications send the same SQL statement way too many times. This SQL assumes you use bind variables correctly.

Then, you can take the sql_id and child_number of a statement and feed them into this baby:-

SELECT * FROM table(DBMS_XPLAN.DISPLAY_CURSOR('&sql_id', &child));

This shows the actual plan from the SQL cache and the full text of the SQL.

I'm not sure you really want to do what you say you want to do, but it's not for me to reason why!

You cannot add properties to a class after it has been JITed.

The closest you could get would be to dynamically create a subtype with Reflection.Emit and copy the existing fields over, but you'd have to update all references to the the object yourself.

You also wouldn't be able to access those properties at compile time.

Something like:

public class Dynamic
{
    public Dynamic Add<T>(string key, T value)
    {
        AssemblyBuilder assemblyBuilder = AppDomain.CurrentDomain.DefineDynamicAssembly(new AssemblyName("DynamicAssembly"), AssemblyBuilderAccess.Run);
        ModuleBuilder moduleBuilder = assemblyBuilder.DefineDynamicModule("Dynamic.dll");
        TypeBuilder typeBuilder = moduleBuilder.DefineType(Guid.NewGuid().ToString());
        typeBuilder.SetParent(this.GetType());
        PropertyBuilder propertyBuilder = typeBuilder.DefineProperty(key, PropertyAttributes.None, typeof(T), Type.EmptyTypes);

        MethodBuilder getMethodBuilder = typeBuilder.DefineMethod("get_" + key, MethodAttributes.Public, CallingConventions.HasThis, typeof(T), Type.EmptyTypes);
        ILGenerator getter = getMethodBuilder.GetILGenerator();
        getter.Emit(OpCodes.Ldarg_0);
        getter.Emit(OpCodes.Ldstr, key);
        getter.Emit(OpCodes.Callvirt, typeof(Dynamic).GetMethod("Get", BindingFlags.Instance | BindingFlags.NonPublic).MakeGenericMethod(typeof(T)));
        getter.Emit(OpCodes.Ret);
        propertyBuilder.SetGetMethod(getMethodBuilder);

        Type type = typeBuilder.CreateType();

        Dynamic child = (Dynamic)Activator.CreateInstance(type);
        child.dictionary = this.dictionary;
        dictionary.Add(key, value);
        return child;
    }

    protected T Get<T>(string key)
    {
        return (T)dictionary[key];
    }

    private Dictionary<string, object> dictionary = new Dictionary<string,object>();
}

I don't have VS installed on this machine so let me know if there are any massive bugs (well... other than the massive performance problems, but I didn't write the specification!)

Now you can use it:

Dynamic d = new Dynamic();
d = d.Add("MyProperty", 42);
Console.WriteLine(d.GetType().GetProperty("MyProperty").GetValue(d, null));

You could also use it like a normal property in a language that supports late binding (for example, VB.NET)

Found another (manual) answer which worked well for me

1. Select the column.
2. Choose Data tab
3. Text to Columns - opens new box
4. (choose Delimited), Next
5. (uncheck all boxes, use "none" for text qualifier), Next
6. use the ymd option from the Date dropdown.
7. Click Finish

Any time you do a remove() or a removeAll(), you should call

  validate();
  repaint();

after you have completed add()'ing the new components.

Calling validate() or revalidate() is mandatory when you do a remove() - see the relevant javadocs.

My own testing indicates that repaint() is also necessary. I'm not sure exactly why.

is there a better syntax?

No. CSS' or operator (,) does not permit groupings. It's essentially the lowest-precedence logical operator in selectors, so you must use .a.c,.b.c.

There are 5 6 NINE (or 63*, depending how you count) different ways to write multi-line strings in YAML.

TL;DR

• Use > most of the time: interior line breaks are stripped out, although you get one at the end:

  key: >
    Your long
    string here.
  

• Use | if you want those linebreaks to be preserved as \n (for instance, embedded markdown with paragraphs).

  key: |
    ### Heading
  
    * Bullet
    * Points
  

• Use >- or |- instead if you don't want a linebreak appended at the end.

• Use "..." if you need to split lines in the middle of words or want to literally type linebreaks as \n:

  key: "Antidisestab\
   lishmentarianism.\n\nGet on it."
  

• YAML is crazy.

Block scalar styles (>, |)

These allow characters such as \ and " without escaping, and add a new line (\n) to the end of your string.

> Folded style removes single newlines within the string (but adds one at the end, and converts double newlines to singles):

Key: >
  this is my very very very
  long string

? this is my very very very long string\n

| Literal style turns every newline within the string into a literal newline, and adds one at the end:

Key: |
  this is my very very very 
  long string

? this is my very very very\nlong string\n

Here's the official definition from the YAML Spec 1.2

Scalar content can be written in block notation, using a literal style (indicated by “|”) where all line breaks are significant. Alternatively, they can be written with the folded style (denoted by “>”) where each line break is folded to a space unless it ends an empty or a more-indented line.

Block styles with block chomping indicator (>-, |-, >+, |+)

You can control the handling of the final new line in the string, and any trailing blank lines (\n\n) by adding a block chomping indicator character:

• >, |: "clip": keep the line feed, remove the trailing blank lines.
• >-, |-: "strip": remove the line feed, remove the trailing blank lines.
• >+, |+: "keep": keep the line feed, keep trailing blank lines.

"Flow" scalar styles (, ", ')

These have limited escaping, and construct a single-line string with no new line characters. They can begin on the same line as the key, or with additional newlines first.

plain style (no escaping, no # or : combinations, limits on first character):

Key: this is my very very very 
  long string

double-quoted style (\ and " must be escaped by \, newlines can be inserted with a literal \n sequence, lines can be concatenated without spaces with trailing \):

Key: "this is my very very \"very\" loooo\
  ng string.\n\nLove, YAML."

→ "this is my very very \"very\" loooong string.\n\nLove, YAML."

single-quoted style (literal ' must be doubled, no special characters, possibly useful for expressing strings starting with double quotes):

Key: 'this is my very very "very"
  long string, isn''t it.'

→ "this is my very very \"very\" long string, isn't it."

Summary

In this table, _ means space character. \n means "newline character" (\n in JavaScript), except for the "in-line newlines" row, where it means literally a backslash and an n).

                      >     |            "     '     >-     >+     |-     |+

  "very \"long\" 'string' with\nparagraph gap, \\n and spaces.",

  "very \"long\" 'string' with\nparagraph gap, \\n and spaces.", 
  "very \"long\" 'string' with\nparagraph gap, \\n and         spaces."
]

Block styles with indentation indicators

Just in case the above isn't enough for you, you can add a "block indentation indicator" (after your block chomping indicator, if you have one):

- >8
        My long string
        starts over here
- |+1
 This one
 starts here

Addendum

If you insert extra spaces at the start of not-the-first lines in Folded style, they will be kept, with a bonus newline. This doesn't happen with flow styles:

- >
    my long
      string
- my long
    string

? ["my long\n string\n", "my long string"]

I can't even.

*2 block styles, each with 2 possible block chomping indicators (or none), and with 9 possible indentation indicators (or none), 1 plain style and 2 quoted styles: 2 x (2 + 1) x (9 + 1) + 1 + 2 = 63

Some of this information has also been summarised here.

var desired = stringToReplace.replace(/[^\w\s]/gi, '')

As was mentioned in the comments it's easier to do this as a whitelist - replace the characters which aren't in your safelist.

The caret (^) character is the negation of the set [...], gi say global and case-insensitive (the latter is a bit redundant but I wanted to mention it) and the safelist in this example is digits, word characters, underscores (\w) and whitespace (\s).

String[] fileSizeUnits = {"bytes", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB"};

public String calculateProperFileSize(double bytes){
    String sizeToReturn = "";
    int index = 0;
    for(index = 0; index < fileSizeUnits.length; index++){
        if(bytes < 1024){
            break;
        }
        bytes = bytes / 1024;
    }

    System.out.println("File size in proper format: " + bytes + " " + fileSizeUnits[index]);
    sizeToReturn = String.valueOf(bytes) + " " + fileSizeUnits[index];
    return sizeToReturn;
}

Just add more file units (if any missing), and you will see unit size up to that unit (if your file has that much length):

Finally got this error to go away on a restore. I moved to SQL2012 out of frustration, but I guess this would probably still work on 2008R2. I had to use the logical names:

RESTORE FILELISTONLY
FROM DISK = ‘location of your.bak file’

And from there I ran a restore statement with MOVE using logical names.

RESTORE DATABASE database1
FROM DISK = '\\database path\database.bak'
WITH
MOVE 'File_Data' TO 'E:\location\database.mdf',
MOVE 'File_DOCS' TO 'E:\location\database_1.ndf',
MOVE 'file' TO 'E:\location\database_2.ndf',
MOVE 'file' TO 'E:\location\database_3.ndf',
MOVE 'file_Log' TO 'E:\location\database.ldf'

When it was done restoring, I almost wept with joy.

Good luck!

Your title question and your example are completely different. I'll start by answering the title question:

$("a").removeAttr("href");

And as far as not requiring an href, the generally accepted way of doing this is:

<a href"#" onclick="doWork(); return false;">link</a>

The return false is necessary so that the href doesn't actually go anywhere.

1. Go to "Microsoft Visual C++ Compiler for Python 2.7" and continue based on "System Requirements" (this is what I did to put below steps together).

2. Install setuptools (setuptools 6.0 or later is required for Python to automatically detect this compiler package) either by: pip install setuptools or download "Setuptools bootstrapping installer" source from, save this file somwhere on your filestystem as "ez_python.py" and install with: python ez_python.py

3. Install wheel (wheel is recommended for producing pre-built binary packages). You can install it with: pip install wheel

4. Open Windows elevated Command Prompt cmd.exe (with "Run as administrator") to install "Microsoft Visual C++ Compiler for Python 2.7" for all users. You can use following command to do so: msiexec /i C:\users\jozko\download\VCForPython27.msi ALLUSERS=1 just use your own path to file: msiexec /i <path to MSI> ALLUSERS=1

5. Now you should be able to install pycrypto with: pip install pycrypto

Now I've got the same problem, and for some reasons I decided to avoid decorators, factories and metaclasses. I did it like this:

Main file

def _alt(func):
    import functools
    @functools.wraps(func)
    def init(self, *p, **k):
        if hasattr(self, "parent_initialized"):
            return
        else:
            self.parent_initialized = True
            func(self, *p, **k)

    return init


class Parent:
    # Empty dictionary, shouldn't ever be filled with anything else
    parent_cache = {}

    def __new__(cls, n, *args, **kwargs):

        # Checks if object with this ID (n) has been created
        if n in cls.parent_cache:

            # It was, return it
            return cls.parent_cache[n]

        else:

            # Check if it was modified by this function
            if not hasattr(cls, "parent_modified"):
                # Add the attribute
                cls.parent_modified = True
                cls.parent_cache = {}

                # Apply it
                cls.__init__ = _alt(cls.__init__)

            # Get the instance
            obj = super().__new__(cls)

            # Push it to cache
            cls.parent_cache[n] = obj

            # Return it
            return obj

Example classes

class A(Parent):

    def __init__(self, n):
        print("A.__init__", n)


class B(Parent):

    def __init__(self, n):
        print("B.__init__", n)

In use

>>> A(1)
A.__init__ 1  # First A(1) initialized 
<__main__.A object at 0x000001A73A4A2E48>
>>> A(1)      # Returned previous A(1)
<__main__.A object at 0x000001A73A4A2E48>
>>> A(2)
A.__init__ 2  # First A(2) initialized
<__main__.A object at 0x000001A7395D9C88>
>>> B(2)
B.__init__ 2  # B class doesn't collide with A, thanks to separate cache
<__main__.B object at 0x000001A73951B080>

• Warning: You shouldn't initialize Parent, it will collide with other classes - unless you defined separate cache in each of the children, that's not what we want.
• Warning: It seems a class with Parent as grandparent behaves weird. [Unverified]

Try it online!

$.ajax({
        url: 'http://url.of.my.server/submit',
        dataType: "jsonp",
        jsonp: 'callback',
        jsonpCallback: 'jsonp_callback'
    });

jsonp is the querystring parameter name that is defined to be acceptable by the server while the jsonpCallback is the javascript function name to be executed at the client.
When you use such url:

url: 'http://url.of.my.server/submit?callback=?'

the question mark ? at the end instructs jQuery to generate a random function while the predfined behavior of the autogenerated function will just invoke the callback -the sucess function in this case- passing the json data as a parameter.

$.ajax({
        url: 'http://url.of.my.server/submit?callback=?',
        success: function (data, status) {
            mySurvey.closePopup();
        },
        error: function (xOptions, textStatus) {
            mySurvey.closePopup();
        }
    });

The same goes here if you are using $.getJSON with ? placeholder it will generate a random function while the predfined behavior of the autogenerated function will just invoke the callback:

$.getJSON('http://url.of.my.server/submit?callback=?',function(data){
//process data here
});

As I stated in comment i would use a box layout for this.

JPanel panel = new JPanel();
panel.setLayout(new BoxLayout());

JButton button = new JButton("Button1");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button2");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button3");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

add(panel);

The method I used included part of Richard Harrison's method:

So, install SQL Server 2008 Express edition,

This requires the download of the Web Platform Installer "wpilauncher_n.exe" Once you have this installed click on the database selection ( you are also required to download Frameworks and Runtimes)

After instalation go to the windows command prompt and:

use sqlcmd -S \SQLExpress (whilst logged in as administrator)

then issue the following command.

restore filelistonly from disk='c:\temp\mydbName-2009-09-29-v10.bak'; GO This will list the contents of the backup - what you need is the first fields that tell you the logical names - one will be the actual database and the other the log file.

RESTORE DATABASE mydbName FROM disk='c:\temp\mydbName-2009-09-29-v10.bak' WITH MOVE 'mydbName' TO 'c:\temp\mydbName_data.mdf', MOVE 'mydbName_log' TO 'c:\temp\mydbName_data.ldf'; GO

I fired up Web Platform Installer and from the what's new tab I installed SQL Server Management Studio and browsed the db to make sure the data was there...

At that point i tried the tool included with MSSQL "SQL Import and Export Wizard" but the result of the csv dump only included the column names...

So instead I just exported results of queries like "select * from users" from the SQL Server Management Studio

You can update with MERGE Command with much more control over MATCHED and NOT MATCHED:(I slightly changed the source code to demonstrate my point)

USE tempdb;
GO
IF(OBJECT_ID('target') > 0)DROP TABLE dbo.target
IF(OBJECT_ID('source') > 0)DROP TABLE dbo.source
CREATE TABLE dbo.Target
    (
      EmployeeID INT ,
      EmployeeName VARCHAR(100) ,
      CONSTRAINT Target_PK PRIMARY KEY ( EmployeeID )
    );
CREATE TABLE dbo.Source
    (
      EmployeeID INT ,
      EmployeeName VARCHAR(100) ,
      CONSTRAINT Source_PK PRIMARY KEY ( EmployeeID )
    );
GO
INSERT  dbo.Target
        ( EmployeeID, EmployeeName )
VALUES  ( 100, 'Mary' );
INSERT  dbo.Target
        ( EmployeeID, EmployeeName )
VALUES  ( 101, 'Sara' );
INSERT  dbo.Target
        ( EmployeeID, EmployeeName )
VALUES  ( 102, 'Stefano' );

GO
INSERT  dbo.Source
        ( EmployeeID, EmployeeName )
VALUES  ( 100, 'Bob' );
INSERT  dbo.Source
        ( EmployeeID, EmployeeName )
VALUES  ( 104, 'Steve' );
GO

SELECT * FROM dbo.Source
SELECT * FROM dbo.Target

MERGE Target AS T
USING Source AS S
ON ( T.EmployeeID = S.EmployeeID )
WHEN MATCHED THEN
    UPDATE SET T.EmployeeName = S.EmployeeName + '[Updated]';
GO 
SELECT '-------After Merge----------'
SELECT * FROM dbo.Source
SELECT * FROM dbo.Target

I had the same issue while executing my selenium tests and I removed the selenium dependencies from the ModulePath to ClassPath under Build path in eclipse and it worked!

I had the same problem, which went away after I listed my library last: gcc prog.c -lm

This answer fails in a couple of edge cases (see comments). The accepted solution above will handle these. str.splitlines() is the way to go. I will leave this answer nevertheless as reference.

Old (incorrect) answer:

s =  \
"""line1
line2
line3
"""

lines = s.split('\n')
print(lines)
for line in lines:
    print(line)

For print session data you do not need to use print_r() function every time .

If you use it then it will be non-readable format.Data will be looks very dirty.

But if you use my function all you have to do is to use p()-Funtion and pass data into it. //create new file into application/cms_helper.php and load helper cms into //autoload or on controller

/*Copy Code for p function from here and paste into cms_helper.php in application/helpers folder */

   //@parram $data-array,$d-if true then die by default it is false
   //@author Your name

    function p($data,$d = false){

          echo "<pre>"; 
             print_r($data);
          echo "</pre>"; 

        if($d == TRUE){
             die();
          } 
      }

Just remember to load cms_helper into your project or controller using $this->load->helper('cms'); use bellow code into your controller or model it will works just GREAT.

 p($this->session->all_userdata()); // it will apply pre to your sesison data and other array as  well

Here is some main point which differentiate Spring, Spring MVC and Spring Boot :

Spring :

1. Main Difference is "Test-ability".
2. Spring come with the DI and IOC. Through which all hard-work done by system we don't need to do any kind of work(like, normally we define object of class manually but through Di we just annotate with @Service or @Component - matching class manage those).
3. Through @Autowired annotation we easily mock() it at unit testing time.
4. Duplication and Plumbing code. In JDBC we writing same code multiple time to perform any kind of database operation Spring solve that issue through Hibernate and ORM.
5. Good Integration with other frameworks. Like Hibernate, ORM, Junit & Mockito.

Spring MVC

1. Spring MVC framework is module of spring which provide facility HTTP oriented web application development.
2. Spring MVC have clear code separation on input logic(controller), business logic(model), and UI logic(view).
3. Spring MVC pattern help to develop flexible and loosely coupled web applications.
4. Provide various hard coded way to customise your application based on your need.

Spring Boot :

1. Create of Quick Application so that, instead of manage single big web application we divide them individually into different Microservices which have their own scope & capability.
2. Auto Configuration using Web Jar : In normal Spring there is lot of configuration like DispatcherServlet, Component Scan, View Resolver, Web Jar, XMLs. (For example if I would like to configure datasource, Entity Manager Transaction Manager Factory). Configure automatically when it's not available using class-path.
3. Comes with Default Spring Starters, which come with some default Spring configuration dependency (like Spring Core, Web-MVC, Jackson, Tomcat, Validation, Data Binding, Logging). Don't worry about versioning issue as well.

(Evolution like : Spring -> Spring MVC -> Spring Boot, So newer version have the compatibility of old version features.) Note : It doesn't contain all point.

Use std::this_thread::sleep_for:

#include <chrono>
#include <thread>

std::chrono::milliseconds timespan(111605); // or whatever

std::this_thread::sleep_for(timespan);

There is also the complementary std::this_thread::sleep_until.

Prior to C++11, C++ had no thread concept and no sleep capability, so your solution was necessarily platform dependent. Here's a snippet that defines a sleep function for Windows or Unix:

#ifdef _WIN32
    #include <windows.h>

    void sleep(unsigned milliseconds)
    {
        Sleep(milliseconds);
    }
#else
    #include <unistd.h>
    
    void sleep(unsigned milliseconds)
    {
        usleep(milliseconds * 1000); // takes microseconds
    }
#endif

But a much simpler pre-C++11 method is to use boost::this_thread::sleep.

    public MainWindow()
    {
        // This button needs to exist on your form.
        myButton.Click += myButton_Click;
    }

    void myButton_Click(object sender, RoutedEventArgs e)
    {
        MessageBox.Show("Message here");
        this.Close();
    }

You typically set the port at the server using the rmiregistry command. You can set the port on the command line, or it will default to 1099

By the rational of making everything multiplication I add the entry at the end of the list

    clc; clear all;
    V = rand(1024*1024*32,1);
    N = 10;
    tic; for i=1:N, V1 = V/norm(V);         end; toc % 4.5 s
    tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 7.5 s
    tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 4.9 s
    tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 6.8 s
    tic; for i=1:N, V1 = V/norm(V);         end; toc % 4.7 s
    tic; for i=1:N, d = 1/norm(V); V1 = V*d;end; toc % 4.9 s
    tic; for i=1:N, d = norm(V)^-1; V1 = V*d;end;toc % 4.4 s

Frank Heikens answer will only update database ownership. Often, you also want to update ownership of contained objects (including tables). Starting with Postgres 8.2, REASSIGN OWNED is available to simplify this task.

IMPORTANT EDIT!

Never use REASSIGN OWNED when the original role is postgres, this could damage your entire DB instance. The command will update all objects with a new owner, including system resources (postgres0, postgres1, etc.)

First, connect to admin database and update DB ownership:

psql
postgres=# REASSIGN OWNED BY old_name TO new_name;

This is a global equivalent of ALTER DATABASE command provided in Frank's answer, but instead of updating a particular DB, it change ownership of all DBs owned by 'old_name'.

The next step is to update tables ownership for each database:

psql old_name_db
old_name_db=# REASSIGN OWNED BY old_name TO new_name;

This must be performed on each DB owned by 'old_name'. The command will update ownership of all tables in the DB.

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

std::copy is what you're looking for.

Oskar Persson's answer is the best way to handle it because makes it easier to pass the data to the context and treat it normally from the template as we get the object instances (easily iterable to get props) instead of a plain value list.

After that you can just easily get the wanted prop:

for employee in employees:
    print(employee.eng_name)

Or in the template:

{% for employee in employees %}

    <p>{{ employee.eng_name }}</p>

{% endfor %}

Call getActivity() method inside the onActivityCreated()

I know it's been a while on this question, but I was just looking for the same answer and found this seems to be the simplest solution:

select * from sales where datediff(dd, salesDate, '20101111') = 0

I actually use it more to find things within the last day or two, so my version looks like this:

select * from sales where datediff(dd, salesDate, getdate()) = 0

And by changing the 0 for today to a 1 I get yesterday's transactions, 2 is the day before that, and so on. And if you want everything for the last week, just change the equals to a less-than-or-equal-to:

select * from sales where datediff(dd, salesDate, getdate()) <= 7

The size of a structure is greater than the sum of its parts because of what is called packing. A particular processor has a preferred data size that it works with. Most modern processors' preferred size if 32-bits (4 bytes). Accessing the memory when data is on this kind of boundary is more efficient than things that straddle that size boundary.

For example. Consider the simple structure:

struct myStruct
{
   int a;
   char b;
   int c;
} data;

If the machine is a 32-bit machine and data is aligned on a 32-bit boundary, we see an immediate problem (assuming no structure alignment). In this example, let us assume that the structure data starts at address 1024 (0x400 - note that the lowest 2 bits are zero, so the data is aligned to a 32-bit boundary). The access to data.a will work fine because it starts on a boundary - 0x400. The access to data.b will also work fine, because it is at address 0x404 - another 32-bit boundary. But an unaligned structure would put data.c at address 0x405. The 4 bytes of data.c are at 0x405, 0x406, 0x407, 0x408. On a 32-bit machine, the system would read data.c during one memory cycle, but would only get 3 of the 4 bytes (the 4th byte is on the next boundary). So, the system would have to do a second memory access to get the 4th byte,

Now, if instead of putting data.c at address 0x405, the compiler padded the structure by 3 bytes and put data.c at address 0x408, then the system would only need 1 cycle to read the data, cutting access time to that data element by 50%. Padding swaps memory efficiency for processing efficiency. Given that computers can have huge amounts of memory (many gigabytes), the compilers feel that the swap (speed over size) is a reasonable one.

Unfortunately, this problem becomes a killer when you attempt to send structures over a network or even write the binary data to a binary file. The padding inserted between elements of a structure or class can disrupt the data sent to the file or network. In order to write portable code (one that will go to several different compilers), you will probably have to access each element of the structure separately to ensure the proper "packing".

On the other hand, different compilers have different abilities to manage data structure packing. For example, in Visual C/C++ the compiler supports the #pragma pack command. This will allow you to adjust data packing and alignment.

For example:

#pragma pack 1
struct MyStruct
{
    int a;
    char b;
    int c;
    short d;
} myData;

I = sizeof(myData);

I should now have the length of 11. Without the pragma, I could be anything from 11 to 14 (and for some systems, as much as 32), depending on the default packing of the compiler.

These methods will work, but without an explicit id as a PK then determining which rows to delete could be a problem. The bounce out into a temp table delete from original and re-insert without the dupes seems to be the simplest.
