I discovered while following the above suggestions that for line in f: does not work for a pandas dataframe (not that anyone said it would) because the end of file in a dataframe is the last column, not the last row. for example if you have a data frame with 3 fields (columns) and 9 records (rows), the for loop will stop after the 3rd iteration, not after the 9th iteration.

I have done some testing and using CSS3 to redefine the scrollbars works and you get to keep your Overflow:scroll; or Overflow:auto

I ended up with something like this...

::-webkit-scrollbar {
    width: 15px;
    height: 15px;
    border-bottom: 1px solid #eee; 
    border-top: 1px solid #eee;
}
::-webkit-scrollbar-thumb {
    border-radius: 8px;
    background-color: #C3C3C3;
    border: 2px solid #eee;
}

::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.2); 
} 

The only down side which I have not yet been able to figure out is how to interact with the scrollbars on iProducts but you can interact with the content to scroll it

It is very useful when you want to perform an "ordered update".

MS SQL does not allow you to use ORDER BY with UPDATE, but with help of CTE you can do it that way:

WITH cte AS
(
    SELECT TOP(5000) message_compressed, message, exception_compressed, exception
    FROM logs
    WHERE Id >= 5519694 
    ORDER BY Id
)
UPDATE  cte
SET     message_compressed = COMPRESS(message), exception_compressed = COMPRESS(exception)

Look here for more info: How to update and order by using ms sql

If you operate on a large dataset, it is very possible that arrays will be used. For me creating a few arrays from 500 000 rows and 30 columns worksheet caused this error. I solved it simply by using the line below to get rid of array which is no longer necessary to me, before creating another one:

Erase vArray

Also if only 2 columns out of 30 are used, it is a good idea to create two 1-column arrays instead of one with 30 columns. It doesn't affect speed, but there will be a difference in memory usage.

tl;dr

• Use modern java.time classes as much as possible, rather than the terrible legacy classes.
• Always specify your desired/expected time zone or offset-from-UTC rather than rely implicitly on JVM’s current default.

Example code (without exception-handling):

XMLGregorianCalendar xgc = 
    DatatypeFactory                           // Data-type converter.
    .newInstance()                            // Instantiate a converter object.
    .newXMLGregorianCalendar(                 // Converter going from `GregorianCalendar` to `XMLGregorianCalendar`.
        GregorianCalendar.from(               // Convert from modern `ZonedDateTime` class to legacy `GregorianCalendar` class.
            LocalDate                         // Modern class for representing a date-only, without time-of-day and without time zone.
            .parse( "2014-01-07" )            // Parsing strings in standard ISO 8601 format is handled by default, with no need for custom formatting pattern. 
            .atStartOfDay( ZoneOffset.UTC )   // Determine the first moment of the day as seen in UTC. Returns a `ZonedDateTime` object.
        )                                     // Returns a `GregorianCalendar` object.
    )                                         // Returns a `XMLGregorianCalendar` object.
;

Parsing date-only input string into an object of XMLGregorianCalendar class

Avoid the terrible legacy date-time classes whenever possible, such as XMLGregorianCalendar, GregorianCalendar, Calendar, and Date. Use only modern java.time classes.

When presented with a string such as "2014-01-07", parse as a LocalDate.

LocalDate.parse( "2014-01-07" )

To get a date with time-of-day, assuming you want the first moment of the day, specify a time zone. Let java.time determine the first moment of the day, as it is not always 00:00:00.0 in some zones on some dates.

LocalDate.parse( "2014-01-07" )
         .atStartOfDay( ZoneId.of( "America/Montreal" ) )

This returns a ZonedDateTime object.

ZonedDateTime zdt = 
        LocalDate
        .parse( "2014-01-07" )
        .atStartOfDay( ZoneId.of( "America/Montreal" ) )
;

zdt.toString() = 2014-01-07T00:00-05:00[America/Montreal]

But apparently, you want the start-of-day as seen in UTC (an offset of zero hours-minutes-seconds). So we specify ZoneOffset.UTC constant as our ZoneId argument.

ZonedDateTime zdt = 
        LocalDate
        .parse( "2014-01-07" )
        .atStartOfDay( ZoneOffset.UTC )
;

zdt.toString() = 2014-01-07T00:00Z

The Z on the end means UTC (an offset of zero), and is pronounced “Zulu”.

If you must work with legacy classes, convert to GregorianCalendar, a subclass of Calendar.

GregorianCalendar gc = GregorianCalendar.from( zdt ) ;

gc.toString() = java.util.GregorianCalendar[time=1389052800000,areFieldsSet=true,areAllFieldsSet=true,lenient=true,zone=sun.util.calendar.ZoneInfo[id="UTC",offset=0,dstSavings=0,useDaylight=false,transitions=0,lastRule=null],firstDayOfWeek=2,minimalDaysInFirstWeek=4,ERA=1,YEAR=2014,MONTH=0,WEEK_OF_YEAR=2,WEEK_OF_MONTH=2,DAY_OF_MONTH=7,DAY_OF_YEAR=7,DAY_OF_WEEK=3,DAY_OF_WEEK_IN_MONTH=1,AM_PM=0,HOUR=0,HOUR_OF_DAY=0,MINUTE=0,SECOND=0,MILLISECOND=0,ZONE_OFFSET=0,DST_OFFSET=0]

Apparently, you really need an object of the legacy class XMLGregorianCalendar. If the calling code cannot be updated to use java.time, convert.

XMLGregorianCalendar xgc = 
        DatatypeFactory
        .newInstance()
        .newXMLGregorianCalendar( gc ) 
;

Actually, that code requires a try-catch.

try
{
    XMLGregorianCalendar xgc =
            DatatypeFactory
                    .newInstance()
                    .newXMLGregorianCalendar( gc );
}
catch ( DatatypeConfigurationException e )
{
    e.printStackTrace();
}

xgc = 2014-01-07T00:00:00.000Z

Putting that all together, with appropriate exception-handling.

// Given an input string such as "2014-01-07", return a `XMLGregorianCalendar` object
// representing first moment of the day on that date as seen in UTC. 
static public XMLGregorianCalendar getXMLGregorianCalendar ( String input )
{
    Objects.requireNonNull( input );
    if( input.isBlank() ) { throw new IllegalArgumentException( "Received empty/blank input string for date argument. Message # 11818896-7412-49ba-8f8f-9b3053690c5d." ) ; }
    XMLGregorianCalendar xgc = null;
    ZonedDateTime zdt = null;

    try
    {
        zdt =
                LocalDate
                        .parse( input )
                        .atStartOfDay( ZoneOffset.UTC );
    }
    catch ( DateTimeParseException e )
    {
        throw new IllegalArgumentException( "Faulty input string for date does not comply with standard ISO 8601 format. Message # 568db0ef-d6bf-41c9-8228-cc3516558e68." );
    }

    GregorianCalendar gc = GregorianCalendar.from( zdt );
    try
    {
        xgc =
                DatatypeFactory
                        .newInstance()
                        .newXMLGregorianCalendar( gc );
    }
    catch ( DatatypeConfigurationException e )
    {
        e.printStackTrace();
    }

    Objects.requireNonNull( xgc );
    return xgc ;
}

Usage.

String input = "2014-01-07";
XMLGregorianCalendar xgc = App.getXMLGregorianCalendar( input );

Dump to console.

System.out.println( "xgc = " + xgc );

xgc = 2014-01-07T00:00:00.000Z

Modern date-time classes versus legacy

Date-time != String

Do not conflate a date-time value with its textual representation. We parse strings to get a date-time object, and we ask the date-time object to generate a string to represent its value. The date-time object has no ‘format’, only strings have a format.

So shift your thinking into two separate modes: model and presentation. Determine the date-value you have in mind, applying appropriate time zone, as the model. When you need to display that value, generate a string in a particular format as expected by the user.

Avoid legacy date-time classes

The Question and other Answers all use old troublesome date-time classes now supplanted by the java.time classes.

ISO 8601

Your input string "2014-01-07" is in standard ISO 8601 format.

The T in the middle separates date portion from time portion.

The Z on the end is short for Zulu and means UTC.

Fortunately, the java.time classes use the ISO 8601 formats by default when parsing/generating strings. So no need to specify a formatting pattern.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate ld = LocalDate.parse( "2014-01-07" ) ;

ld.toString(): 2014-01-07

Start of day ZonedDateTime

If you want to see the first moment of that day, specify a ZoneId time zone to get a moment on the timeline, a ZonedDateTime. The time zone is crucial because the date varies around the globe by zone. A few minutes after midnight in Paris France is a new day while still “yesterday” in Montréal Québec.

Never assume the day begins at 00:00:00. Anomalies such as Daylight Saving Time (DST) means the day may begin at another time-of-day such as 01:00:00. Let java.time determine the first moment.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = ld.atStartOfDay( z ) ;

zdt.toString(): 2014-01-07T00:00:00Z

For your desired format, generate a string using the predefined formatter DateTimeFormatter.ISO_LOCAL_DATE_TIME and then replace the T in the middle with a SPACE.

String output = zdt.format( DateTimeFormatter.ISO_LOCAL_DATE_TIME )
                   .replace( "T" , " " ) ; 

2014-01-07 00:00:00

About java.time

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

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

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

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

No special escape sequence is required: you can just type the space directly:

if (char_i_want_to_test == ' ') { 
    // Do something because it is space
}

In ASCII, space is code 32, so you could specify space by '\x20' or even 32, but you really shouldn't do that.

Aside: the word "whitespace" is a catch all for space, tab, newline, and all of that. When you're referring specifically to the ordinary space character, you shouldn't use the term.

For Strawberry Perl, try:

cpan -u

I had the same problem and I solved as follows define an interface like mine

export class Notification {
    id: number;
    heading: string;
    link: string;
}

and in nofificationService write

allNotifications: Notification[]; 
  //NotificationDetail: Notification;  
  private notificationsUrl = 'assets/data/notification.json';  // URL to web api 
  private downloadsUrl = 'assets/data/download.json';  // URL to web api 

  constructor(private httpClient: HttpClient ) { }

  getNotifications(): Observable<Notification[]> {    
       //return this.allNotifications = this.NotificationDetail.slice(0);  
     return this.httpClient.get<Notification[]>

(this.notificationsUrl).pipe(map(res => this.allNotifications = res))
      } 

and in component write

 constructor(private notificationService: NotificationService) {
   }

  ngOnInit() {
      /* get Notifications */
      this.notificationService.getNotifications().subscribe(data => this.notifications = data);
}

A shorthand of the previous solutions is

var myDate = +new Date("2012-02-10T13:19:11+0000");

It does an on the fly type conversion and directly outputs date in millisecond format.

Another way is also using parse method of Date util which only outputs EPOCH time in milliseconds.

var myDate = Date.parse("2012-02-10T13:19:11+0000");

I had this problem and I just realized that if in the server you see the user in the menu SERVER -> USERS AND PRIVILEGES and find the user who has % as HOSTNAME, you can use it instead the root user.

That's all

I can confirm that I have the same bug on Windows 7 using Chrome Version 35 but I share my partial solution who is open a new tab on Chrome and showing a dialog.

For other browser when the user click on cancel automatically close the new print window.

//Chrome's versions > 34 is some bug who stop all javascript when is show a prints preview
//http://stackoverflow.com/questions/23071291/javascript-window-print-in-chrome-closing-new-window-or-tab-instead-of-cancel
if(navigator.userAgent.toLowerCase().indexOf('chrome') > -1) {
    var popupWin = window.open();
    popupWin.window.focus();
    popupWin.document.write('<!DOCTYPE html><html><head>' +
        '<link rel="stylesheet" type="text/css" href="style.css" />' +
        '</head><body onload="window.print()"><div class="reward-body">' + printContents + '</div></html>');
    popupWin.onbeforeunload = function (event) {
        return 'Please use the cancel button on the left side of the print preview to close this window.\n';
    };
}else {
    var popupWin = window.open('', '_blank', 'width=600,height=600,scrollbars=no,menubar=no,toolbar=no,location=no,status=no,titlebar=no');
    popupWin.document.write('<!DOCTYPE html><html><head>' +
        '<link rel="stylesheet" type="text/css" href="style.css" />' +
        '</head><body onload="window.print()"><div class="reward-body">' + printContents + '</div>' +
        '<script>setTimeout(function(){ window.parent.focus(); window.close() }, 100)</script></html>');
}
popupWin.document.close();

-split outputs an array, and you can save it to a variable like this:

$a = -split 'Once  upon    a     time'
$a[0]

Once

Another cute thing, you can have arrays on both sides of an assignment statement:

$a,$b,$c = -split 'Once  upon    a'
$c

a

"\n" = new line
'\n' = \n
"\t" = tab
'\t' = \t

'SELECT * FROM Employ where number = ' + parseInt(val, 10) + ';'

For example, if val is "10" then this will end up building the string:

"SELECT * FROM Employ where number = 10;"

For surfaces it's a bit different than a list of 3-tuples, you should pass in a grid for the domain in 2d arrays.

If all you have is a list of 3d points, rather than some function f(x, y) -> z, then you will have a problem because there are multiple ways to triangulate that 3d point cloud into a surface.

Here's a smooth surface example:

import numpy as np
from mpl_toolkits.mplot3d import Axes3D  
# Axes3D import has side effects, it enables using projection='3d' in add_subplot
import matplotlib.pyplot as plt
import random

def fun(x, y):
    return x**2 + y

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
x = y = np.arange(-3.0, 3.0, 0.05)
X, Y = np.meshgrid(x, y)
zs = np.array(fun(np.ravel(X), np.ravel(Y)))
Z = zs.reshape(X.shape)

ax.plot_surface(X, Y, Z)

ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')

plt.show()

I just had this issue and was doing exactly as was documented and it still was not working.

Look at your error message and make sure you do not have any special characters copied in. I was getting the error

SyntaxError: illegal character @(shell):1:43

When I went to character 43 it was just the start of my object ID, after the open quotes, exactly as I pasted it in. I put my cursor there and hit backspace nothing appeared to happen when it should have removed the open quote. I hit backspace again and it removed the open quote, then I put the quote back in and executed the query and it worked, despite looking exactly the same.

I was doing development in WebMatrix and copied the object id from the console. Whenever you copy from the console in WebMatrix you're likely to pick up some invisible characters that will cause errors.

Yes: replace_all is one of the boost string algorithms:

Although it's not a standard library, it has a few things on the standard library:

1. More natural notation based on ranges rather than iterator pairs. This is nice because you can nest string manipulations (e.g., replace_all nested inside a trim). That's a bit more involved for the standard library functions.
2. Completeness. This isn't hard to be 'better' at; the standard library is fairly spartan. For example, the boost string algorithms give you explicit control over how string manipulations are performed (i.e., in place or through a copy).

Came across a nice tool for doing this.

node-env-file

Parses and loads environment files (containing ENV variable exports) into Node.js environment, i.e. process.env - Uses this style:

.env

# some env variables

FOO=foo1
BAR=bar1
BAZ=1
QUX=
# QUUX=

You have a CryptoListPresenter _presenter but you are never initializing it. You should either be doing that when you declare it or in your initState() (or another appropriate but called-before-you-need-it method).

One thing I find that helps is that if I know a member is functionally 'final', to actually set it to final as that way the analyzer complains that it hasn't been initialized.

EDIT:

I see diegoveloper beat me to answering this, and that the OP asked a follow up.

@Jake - it's hard for us to tell without knowing exactly what CryptoListPresenter is, but depending on what exactly CryptoListPresenter actually is, generally you'd do final CryptoListPresenter _presenter = new CryptoListPresenter(...);, or

CryptoListPresenter _presenter;

@override
void initState() {
  _presenter = new CryptoListPresenter(...);
}

In IE11, you can see local storage in console on dev tools:

1. Show dev tools (press F12)
2. Click "Console" or press Ctrl+2
3. Type localStorage and press Enter

Also, if you need to clear the localStorage, type localStorage.clear() on console.

I had enough success just catchig socket.timeout and socket.error; although socket.error can be raised for lots of reasons. Be careful.

import socket
import logging

hostname='google.com'
port=443

try:
    sock = socket.create_connection((hostname, port), timeout=3)

except socket.timeout as err:
    logging.error(err)

except socket.error as err:
    logging.error(err)

<script type="text/javascript">
    function clearThis(target){
        if(target.value=='[email protected]'){
        target.value= "";}
    }
    </script>

Is this really what your looking for?

If you are using php-intl to localize your application, you probably want to use ResourceBundle::getLocales() instead of static list that you maintain yourself. It can also give you locales for particular language.

<?php
print_r(ResourceBundle::getLocales(''));

/* Output might show
  * Array
  * (
  *    [0] => af
  *    [1] => af_NA
  *    [2] => af_ZA
  *    [3] => am
  *    [4] => am_ET
  *    [5] => ar
  *    [6] => ar_AE
  *    [7] => ar_BH
  *    [8] => ar_DZ
  *    [9] => ar_EG
  *    [10] => ar_IQ
  *  ...
  */
?>

process.cwd() returns the current working directory,

i.e. the directory from which you invoked the node command.

__dirname returns the directory name of the directory containing the JavaScript source code file

For relative imports you have to:

• a) use relative name

• b) provide anchor explicitly

  importlib.import_module('.c', 'a.b')
  

Of course, you could also just do absolute import instead:

importlib.import_module('a.b.c')

With lattice:

library(lattice)

df <- data.frame(time = 1:10,
                 a = cumsum(rnorm(10)),
                 b = cumsum(rnorm(10)),
                 c = cumsum(rnorm(10)))

form <- as.formula(paste(paste(names(df)[- 1],  collapse = ' + '),  
                         'time',  sep = '~'))

xyplot(form,  data = df,  type = 'b',  outer = TRUE)

I faced to the same problem. I solved it by

1. navigate to HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath and edit the default key with the output of C:\> where python.exe command.
2. navigate to HKEY_CURRENT_USER\Software\Python\PythonCore\3.4\InstallPath\InstallGroup and edit the default key with Python 3.4

Note: My python version is 3.4 and you need to replace 3.4 with your python version.

Normally you can find Registry entries for Python in HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\<version>. You just need to copy those entries to HKEY_CURRENT_USER\Software\Python\PythonCore\<version>

This came up in another question recently. I'll elaborate on my answer from there:

Ellipsis is an object that can appear in slice notation. For example:

myList[1:2, ..., 0]

Its interpretation is purely up to whatever implements the __getitem__ function and sees Ellipsis objects there, but its main (and intended) use is in the numpy third-party library, which adds a multidimensional array type. Since there are more than one dimensions, slicing becomes more complex than just a start and stop index; it is useful to be able to slice in multiple dimensions as well. E.g., given a 4x4 array, the top left area would be defined by the slice [:2,:2]:

>>> a
array([[ 1,  2,  3,  4],
       [ 5,  6,  7,  8],
       [ 9, 10, 11, 12],
       [13, 14, 15, 16]])

>>> a[:2,:2]  # top left
array([[1, 2],
       [5, 6]])

Extending this further, Ellipsis is used here to indicate a placeholder for the rest of the array dimensions not specified. Think of it as indicating the full slice [:] for all the dimensions in the gap it is placed, so for a 3d array, a[...,0] is the same as a[:,:,0] and for 4d, a[:,:,:,0], similarly, a[0,...,0] is a[0,:,:,0] (with however many colons in the middle make up the full number of dimensions in the array).

Interestingly, in python3, the Ellipsis literal (...) is usable outside the slice syntax, so you can actually write:

>>> ...
Ellipsis

Other than the various numeric types, no, I don't think it's used. As far as I'm aware, it was added purely for numpy use and has no core support other than providing the object and corresponding syntax. The object being there didn't require this, but the literal "..." support for slices did.

As a newbie in React world, I came across a similar issues where I could not edit the textarea and struggled with binding. It's worth knowing about controlled and uncontrolled elements when it comes to react.

The value of the following uncontrolled textarea cannot be changed because of value

 <textarea type="text" value="some value"
    onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following uncontrolled textarea can be changed because of use of defaultValue or no value attribute

<textarea type="text" defaultValue="sample" 
    onChange={(event) => this.handleOnChange(event)}></textarea>

<textarea type="text" 
   onChange={(event) => this.handleOnChange(event)}></textarea>

The value of the following controlled textarea can be changed because of how value is mapped to a state as well as the onChange event listener

<textarea value={this.state.textareaValue} 
onChange={(event) => this.handleOnChange(event)}></textarea>

Here is my solution using different syntax. I prefer the auto-bind than manual binding however, if I were to not use {(event) => this.onXXXX(event)} then that would cause the content of textarea to be not editable OR the event.preventDefault() does not work as expected. Still a lot to learn I suppose.

class Editor extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      textareaValue: ''
    }
  }
  handleOnChange(event) {
    this.setState({
      textareaValue: event.target.value
    })
  }
  handleOnSubmit(event) {
    event.preventDefault();
    this.setState({
      textareaValue: this.state.textareaValue + ' [Saved on ' + (new Date()).toLocaleString() + ']'
    })
  }
  render() {
    return <div>
        <form onSubmit={(event) => this.handleOnSubmit(event)}>
          <textarea rows={10} cols={30} value={this.state.textareaValue} 
            onChange={(event) => this.handleOnChange(event)}></textarea>
          <br/>
          <input type="submit" value="Save"/>
        </form>
      </div>
  }
}
ReactDOM.render(<Editor />, document.getElementById("content"));

The versions of libraries are

"babel-cli": "6.24.1",
"babel-preset-react": "6.24.1"
"React & ReactDOM v15.5.4" 

this worked for me.

change varchar column to int

change_column :table_name, :column_name, :integer

got:

PG::DatatypeMismatch: ERROR:  column "column_name" cannot be cast automatically to type integer
HINT:  Specify a USING expression to perform the conversion.

chnged to

change_column :table_name, :column_name, 'integer USING CAST(column_name AS integer)'

Standard C++ has no notion of 'colors'. So what you are asking depends on the operating system.

For Windows, you can check out the SetConsoleTextAttribute function.

On *nix, you have to use the ANSI escape sequences.

holy errors The reason for the code below is to show how to not void main every function and not to type return; for functions...... instead push everything into the sediment for which is the print function prototype... if you need to use useful functions ... you will have to below..... (p.s. this below is for people overwhelmed by these object and T templates which allow different variable declaration types(such as float and char) to use the same passed by value in a user defined function)

char arr[ ] = "This is a test";

string str(arr);


//  You can also assign directly to a string.
str = "This is another string";

can anyone tell me why c++ made arrays into pass by value one at a time and the only way to eliminate spaces and punctuation is the use of string tokens. I couldn't get around the problem when i was trying to delete spaces for a palindrome...

#include <iostream>
#include <iomanip>
using namespace std;
int getgrades(float[]);
int getaverage(float[], float);
int calculateletters(float[], float, float, float[]);
int printResults(float[], float, float, float[]);


int main()
{

int i;
float  maxSize=3, size;
float  lettergrades[5], numericgrades[100], average;

size=getgrades(numericgrades);
average = getaverage(numericgrades, size);
printResults(numericgrades, size, average, lettergrades);
return 0;
}

int getgrades(float a[])
{ 


int i, max=3;

for (i = 0; i <max; i++)
{
    //ask use for input
    cout << "\nPlease Enter grade " << i+1 << " : ";
    cin >> a[i];
    //makes sure that user enters a vlue between 0 and 100

   if(a[i] < 0 || a[i] >100)
    {
        cout << "Wrong input. Please
 enter a value between 0 and 100 only." << endl;
        cout << "\nPlease Reenter grade " << i+1 << " : ";
        cin >> a[i];

        return i;
    }
}
}

int getaverage(float a[], float n) 
{ 
int i;
float sum = 0;
 if (n == 0)
return 0;
for (i = 0; i < n; i++)
sum += a[i];
return sum / n;
}                               


int printResults(float a[], float n, float average, float letters[]) 
{
int i;
cout << "Index Number | input  |
array values address in memory " << endl;

for (i = 0; i < 3; i++)
{
cout <<"     "<< i<<" \t\t"<<setprecision(3)<<
a[i]<<"\t\t" << &a[i] << endl;
}
cout<<"The average of your grades is: "<<setprecision(3)<<average<<endl;

}

Assgining a value that starts with a "=" will kick in formula evaluation and gave in my case the above mentioned error #1004. Prepending it with a space was the ticket for me.

There is the conditional expression:

a if cond else b

but this is an expression, not a statement.

In if statements, the if (or elif or else) can be written on the same line as the body of the block if the block is just one like:

if something: somefunc()
else: otherfunc()

but this is discouraged as a matter of formatting-style.

Just change sizeof with strlen.

Like this:

char *source = "This is an example.";
int i;

for (i = 0; i < strlen(source); i++){

    printf("%c", source[i]);

}

Hover your mouse cursor over the name of the array, then hover over the little (+) icon that appears.

I tried:

internal static void IndentedNewWSDLString(string filePath)
{
    var xml = File.ReadAllText(filePath);
    XDocument doc = XDocument.Parse(xml);
    File.WriteAllText(filePath, doc.ToString());
}

it is working fine as expected.

I agree with somebody's recently deleted post that the differences in performance are so small that, with very very few exceptions, (he got dinged for saying never) you should not make your design decision based upon that.

In your example, where the elements are Objects, the performance difference should be minimal.

If you are dealing with a large number of primitives, an array will offer significantly better performance, both in memory and time.

I did not test the following snippet... hopefully it will point you towards the right direction:

    var jsreader = new JsonTextReader(new StringReader(stringData));
    var json = (JObject)new JsonSerializer().Deserialize(jsreader);
    var tableRows = from p in json["items"]
                 select new
                 {
                     Name = (string)p["Name"],
                     Age = (int)p["Age"],
                     Job = (string)p["Job"]
                 };

HTML (ejs dianmic web page): this is a table list of all users and from nodejs generate the table. NodeJS provide dinamic "<%= user.id %>". simply change for any value like "54"

<span type="button" data-href='/admin/user/del/<%= user.id %>' class="item" 
 data-toggle="modal" data-target="#confirm_delete">
    <div data-toggle="tooltip" data-placement="top" title="Delete" data- 
     toggle="modal">
       <i class="zmdi zmdi-delete"></i> 
    </div>
</span>

<div class="modal fade" id="confirm_delete" tabindex="-1" role="dialog" aria-labelledby="staticModalLabel" aria-hidden="true"
         data-backdrop="static">
  <div class="modal-dialog modal-sm" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="staticModalLabel">Static Modal</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button>
      </div>
      <div class="modal-body">
        <p> This is a static modal, backdrop click will not close it. </p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
          <form method="POST" class="btn-ok">
            <input  type="submit" class="btn btn-danger" value="Confirm"></input>
        </form>
      </div>
    </div>
  </div>
</div>
<!-- end modal static --> 

JS:

    $(document).ready(function(){
        $('#confirm_delete').on('show.bs.modal', function(e) {
            $(this).find('.btn-ok').attr('action', $(e.relatedTarget).data('href'));
        });
    });

Use these following commands, this will solve the error:

sudo apt-get install postgresql

then fire:

sudo apt-get install python-psycopg2

and last:

sudo apt-get install libpq-dev

You cannot use a select statement that assigns values to variables to also return data to the user The below code will work fine, because i have declared 1 local variable and that variable is used in select statement.

 Begin
    DECLARE @name nvarchar(max)
    select @name=PolicyHolderName from Table
    select @name
    END

The below code will throw error "A SELECT statement that assigns a value to a variable must not be combined with data-retrieval operations" Because we are retriving data(PolicyHolderAddress) from table, but error says data-retrieval operation is not allowed when you use some local variable as part of select statement.

 Begin
    DECLARE @name nvarchar(max)
    select 
       @name = PolicyHolderName,
       PolicyHolderAddress 
    from Table
 END

The the above code can be corrected like below,

Begin
    DECLARE @name nvarchar(max)
    DECLARE @address varchar(100)
    select 
       @name = PolicyHolderName,
       @address = PolicyHolderAddress 
    from Table
END

So either remove the data-retrieval operation or add extra local variable. This will resolve the error.

If you want to view the file in the browser, it's also possible using a similar method to the one provided by rufo and Torxed:

The most recent versions of hibernate JPA provider applies the bean validation constraints (JSR 303) like @NotNull to DDL by default (thanks to hibernate.validator.apply_to_ddl property defaults to true). But there is no guarantee that other JPA providers do or even have the ability to do that.

You should use bean validation annotations like @NotNull to ensure, that bean properties are set to a none-null value, when validating java beans in the JVM (this has nothing to do with database constraints, but in most situations should correspond to them).

You should additionally use the JPA annotation like @Column(nullable = false) to give the jpa provider hints to generate the right DDL for creating table columns with the database constraints you want. If you can or want to rely on a JPA provider like Hibernate, which applies the bean validation constraints to DDL by default, then you can omit them.

Auto formatting can be done by

• Select View > Code View Options
• Click the View Options button in the toolbar at the top of Code view or the Code inspector.

Auto Indent Makes your code indent automatically when you press Enter while writing code.

source

Depending on your version ou cannot do it directly, but you could do something hacky like

select top 25 *
from ( 
  select top 75 *
  from   table 
  order by field asc
) a 
order by field desc 

where 'field' is the key.

Opening the debug console in Chrome, or even looking at the html source file (after it is loaded in the browser), make sure that all the paths there are valid (i.e. when you follow a link you get to it's content, and not an error). When something is not valid, fix the path (e.g. get rid of the server specific part and make sure you only refer to files that are part of your extension through paths like /js/jquery-123-min.js).

You can also do this:

git reset --hard <commit-hash>
git push -f origin master

and have everyone else who got the latest bad commits reset:

git reset --hard origin/master

Visual Studio's search in folders is by far the fastest I've found.

I believe it intelligently searches only text (non-binary) files, and subsequent searches in the same folder are extremely fast, unlike with the other tools (likely the text files fit in the windows disk cache).

VS2010 on a regular hard drive, no SSD, takes 1 minute to search a 20GB folder with 26k files, source code and binaries mixed up. 15k files are searched - the rest are likely skipped due to being binary files. Subsequent searches in the same folder are on the order of seconds (until stuff gets evicted form the cache).

The next closest I've found for the same folder was grepWin. Around 3 minutes. I excluded files larger than 2000KB (default). The "Include binary files" setting seems to do nothing in terms of speeding up the search, it looks like binary files are still touched (bug?), but they don't show up in the search results. Subsequent searches all take the same 3 minutes - can't take advantage of hard drive cache. If I restrict to files smaller than 200k, the initial search is 2.5min and subsequent searches are on the order of seconds, about as fast as VS - in the cache.

Agent Ransack and FileSeek are both very slow on that folder, around 20min, due to searching through everything, including giant multi-gigabyte binary files. They search at about 10-20MB per second according to Resource Monitor.

UPDATE: Agent Ransack can be set to search files of certain sizes, and using the <200KB cutoff it's 1:15min for a fresh search and 5s for subsequent searches. Faster than grepWin and as fast as VS overall. It's actually pretty nice if you want to keep several searches in tabs and you don't want to pollute the VS recently searched folders list, and you want to keep the ability to search binaries, which VS doesn't seem to wanna do. Agent Ransack also creates an explorer context menu entry, so it's easy to launch from a folder. Same as grepWin but nicer UI and faster.

My new search setup is Agent Ransack for contents and Everything for file names (awesome tool, instant results!).

Please find the below logic where it works on the condition.

If we simply call taskkill /im applicationname.exe, it will kill only if this process is running. If this process is not running, it will throw an error.

So as to check before takskill is called, a check can be done to make sure execute taskkill will be executed only if the process is running, so that it won't throw error.

tasklist /fi "imagename eq applicationname.exe" |find ":" > nul

if errorlevel 1 taskkill /f /im "applicationname.exe"

    var ele = document.getElementById('newSkill')
    ele.onchange = function(){
            var length = ele.children.length
            for(var i=0; i<length;i++){
                if(ele.children[i].selected){alert(ele.children[i].text)};              
            }
    }   

You can run this in powershell:

[System.Runtime.InteropServices.RuntimeEnvironment]::SystemConfigurationFile

Which outputs this for .net 4:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\config\machine.config

Note however that this might change depending on whether .net is running as 32 or 64 bit which will result in \Framework\ or \Framework64\ respectively.

How about calling a function from within your callback instead of returning a value in sync_call()?

function sync_call(input) {
    var value;

    // Assume the async call always succeed
    async_call(input, function(result) {
        value = result;
        use_value(value);
    } );
}

mainJSON.getJSONArray("source") returns a JSONArray, hence you can remove the new JSONArray.

The JSONArray contructor with an object parameter expects it to be a Collection or Array (not JSONArray)

Try this:

JSONArray jsonMainArr = mainJSON.getJSONArray("source"); 

z-index only works on absolute or relatively positioned elements. I would use an outer div set to position relative. Set the div on top to position absolute to remove it from the flow of the document.

.wrapper {position:relative;width:500px;}_x000D_

I suggest that you add

#!/usr/bin/env python

instead of #!/usr/bin/python at the top of the file. The reason for this is that the python installation may be in different folders in different distros or different computers. By using env you make sure that the system finds python and delegates the script's execution to it.

As said before to make the script executable, something like:

chmod u+x name_of_script.py

should do.

I like to define custom structs locally. So:

// my handler func
func addImage(w http.ResponseWriter, r *http.Request) {

    // define custom type
    type Input struct {
        Url        string  `json:"url"`
        Name       string  `json:"name"`
        Priority   int8    `json:"priority"`
    }

    // define a var 
    var input Input

    // decode input or return error
    err := json.NewDecoder(r.Body).Decode(&input)
    if err != nil {
        w.WriteHeader(400)
        fmt.Fprintf(w, "Decode error! please check your JSON formating.")
        return
    }

    // print user inputs
    fmt.Fprintf(w, "Inputed name: %s", input.Name)

}

I also struggled with this but got it working once I figured out how the paths work in UploadHandler.php: upload_dir and upload_url are about the only settings to look at to get it working. Also check your server error logs for debugging information.

While this is an old question, it's worth updating the answer to C++17. In the standard library there is now the templated function std::size(), which returns the number of elements in both a std container or a C-style array. For example:

#include <iterator>

uint32_t data[] = {10, 20, 30, 40};
auto dataSize = std::size(data);
// dataSize == 4

<LinearLayout
 android:id="@+id/LinearLayouts02"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical"
 android:gravity="bottom|end">

<TextView
android:id="@+id/texts1"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_weight="2"
android:text="@string/forgotpass"
android:padding="7dp"
android:gravity="bottom|center_horizontal"
android:paddingLeft="10dp"
android:layout_marginBottom="30dp"
android:bottomLeftRadius="10dp"
android:bottomRightRadius="50dp"
android:fontFamily="sans-serif-condensed"
android:textColor="@color/colorAccent"
android:textStyle="bold"
android:textSize="16sp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>

</LinearLayout>

The quick and dirty way would be to simple bind to the keyup event.

$('#mytxt').keyup(function(){_x000D_
    $('#divlen').text('you typed ' + this.value.length + ' characters');_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<input type=text id=mytxt >_x000D_
<div id=divlen></div>

But better would be to bind a reusable function to several events. For example also to the change(), so you can also anticipate text changes such as pastes (with the context menu, shortcuts would also be caught by the keyup )

> 2020 Answer = The Easy Way using Google Apps Script (5 Mins)

We had a similar challenge to solve yesterday, and we solved it using a Google Apps Script!

Send Email From an HTML Form Without a Backend (Server) via Google!

The solution takes 5 mins to implement and I've documented with step-by-step instructions: https://github.com/nelsonic/html-form-send-email-via-google-script-without-server

Brief Overview

A. Using the sample script, deploy a Google App Script

Deploy the sample script as a Google Spreadsheet APP Script: google-script-just-email.js

remember to set the TO_ADDRESS in the script to where ever you want the emails to be sent.
and copy the APP URL so you can use it in the next step when you publish the script.

B. Create your HTML Form and Set the action to the App URL

Using the sample html file: index.html create a basic form.

remember to paste your APP URL into the form action in the HTML form.

C. Test the HTML Form in your Browser

Open the HTML Form in your Browser, Input some data & submit it!

Submit the form. You should see a confirmation that it was sent:

Open the inbox for the email address you set (above)

Done.

Everything about this is customisable, you can easily style/theme the form with your favourite CSS Library and Store the submitted data in a Google Spreadsheet for quick analysis.
The complete instructions are available on GitHub:
https://github.com/nelsonic/html-form-send-email-via-google-script-without-server

You'd better go with something like this:

var mouse_is_inside = false;

$(document).ready(function()
{
    $('.form_content').hover(function(){ 
        mouse_is_inside=true; 
    }, function(){ 
        mouse_is_inside=false; 
    });

    $("body").mouseup(function(){ 
        if(! mouse_is_inside) $('.form_wrapper').hide();
    });
});

I am late for this but i want put some more solution relevant to this.

 @GetMapping
public ResponseEntity<List<JSONObject>> getRole() {
    return ResponseEntity.ok(service.getRole());
}

Go to Project setting

CHECK if the project setting is like this,if the module that you want is show in here

IF the module that you want or "Module SDK" is not show or not correct.

then go to the module's build.gradle file to check if the CompileSdkVersion has installed in your computer.

or modifier the CompileSdkVersion to the version that has been installed in your computer.

In my case:I just installed sdk version 29 in my computer but in the module build.gradle file ,I'm setting the CompilerSdkVersion 28

Both are not matched.

Modifier the build.gradle file CompilerSdkVersion 29 which I installed in my computer

It's working!!!

All the examples are great, but I figure I'd add one more to show how working in a "tidy" format simplifies things. Right now the data frame is in "wide" format meaning the variables "a" through "d" are represented in columns. To get to a "tidy" (or long) format, you can use gather() from the tidyr package which shifts the variables in columns "a" through "d" into rows. Then you use the group_by() and summarize() functions to get the mean of each group. If you want to present the data in a wide format, just tack on an additional call to the spread() function.

library(tidyverse)

# Create reproducible df
set.seed(101)
df <- tibble(a   = sample(1:5, 10, replace=T), 
             b   = sample(1:5, 10, replace=T), 
             c   = sample(1:5, 10, replace=T), 
             d   = sample(1:5, 10, replace=T), 
             grp = sample(1:3, 10, replace=T))

# Convert to tidy format using gather
df %>%
    gather(key = variable, value = value, a:d) %>%
    group_by(grp, variable) %>%
    summarize(mean = mean(value)) %>%
    spread(variable, mean)
#> Source: local data frame [3 x 5]
#> Groups: grp [3]
#> 
#>     grp        a     b        c        d
#> * <int>    <dbl> <dbl>    <dbl>    <dbl>
#> 1     1 3.000000   3.5 3.250000 3.250000
#> 2     2 1.666667   4.0 4.666667 2.666667
#> 3     3 3.333333   3.0 2.333333 2.333333

you can render the page in express more easily

 var app   = require('express')();    
    app.set('views', path.join(__dirname, 'views'));
    app.set('view engine', 'jade');
 
    app.get('/signup',function(req,res){      
    res.sendFile(path.join(__dirname,'/signup.html'));
    });

so if u request like http://127.0.0.1:8080/signup that it will render signup.html page under views folder.

NSUserDefaults.standardUserDefaults().setObject(["fr"], forKey: "AppleLanguages")
NSUserDefaults.standardUserDefaults().synchronize()

I think the accepted answer is great, but it seems many people have failed to grasp some fundamental points.

First, Scala's for comprehensions are equivalent to Haskell's do notation, and it is nothing more than a syntactic sugar for composition of multiple monadic operations. As this statement will most likely not help anyone who needs help, let's try again… :-)

Scala's for comprehensions is syntactic sugar for composition of multiple operations with map, flatMap and filter. Or foreach. Scala actually translates a for-expression into calls to those methods, so any class providing them, or a subset of them, can be used with for comprehensions.

First, let's talk about the translations. There are very simple rules:

1. This

   for(x <- c1; y <- c2; z <-c3) {...}
   

   is translated into

   c1.foreach(x => c2.foreach(y => c3.foreach(z => {...})))
   

2. This

   for(x <- c1; y <- c2; z <- c3) yield {...}
   

   is translated into

   c1.flatMap(x => c2.flatMap(y => c3.map(z => {...})))
   

3. This

   for(x <- c; if cond) yield {...}
   

   is translated on Scala 2.7 into

   c.filter(x => cond).map(x => {...})
   

   or, on Scala 2.8, into

   c.withFilter(x => cond).map(x => {...})
   

   with a fallback into the former if method withFilter is not available but filter is. Please see the section below for more information on this.

4. This

   for(x <- c; y = ...) yield {...}
   

   is translated into

   c.map(x => (x, ...)).map((x,y) => {...})
   

When you look at very simple for comprehensions, the map/foreach alternatives look, indeed, better. Once you start composing them, though, you can easily get lost in parenthesis and nesting levels. When that happens, for comprehensions are usually much clearer.

I'll show one simple example, and intentionally omit any explanation. You can decide which syntax was easier to understand.

l.flatMap(sl => sl.filter(el => el > 0).map(el => el.toString.length))

or

for {
  sl <- l
  el <- sl
  if el > 0
} yield el.toString.length

withFilter

Scala 2.8 introduced a method called withFilter, whose main difference is that, instead of returning a new, filtered, collection, it filters on-demand. The filter method has its behavior defined based on the strictness of the collection. To understand this better, let's take a look at some Scala 2.7 with List (strict) and Stream (non-strict):

scala> var found = false
found: Boolean = false

scala> List.range(1,10).filter(_ % 2 == 1 && !found).foreach(x => if (x == 5) found = true else println(x))
1
3
7
9

scala> found = false
found: Boolean = false

scala> Stream.range(1,10).filter(_ % 2 == 1 && !found).foreach(x => if (x == 5) found = true else println(x))
1
3

The difference happens because filter is immediately applied with List, returning a list of odds -- since found is false. Only then foreach is executed, but, by this time, changing found is meaningless, as filter has already executed.

In the case of Stream, the condition is not immediatelly applied. Instead, as each element is requested by foreach, filter tests the condition, which enables foreach to influence it through found. Just to make it clear, here is the equivalent for-comprehension code:

for (x <- List.range(1, 10); if x % 2 == 1 && !found) 
  if (x == 5) found = true else println(x)

for (x <- Stream.range(1, 10); if x % 2 == 1 && !found) 
  if (x == 5) found = true else println(x)

This caused many problems, because people expected the if to be considered on-demand, instead of being applied to the whole collection beforehand.

Scala 2.8 introduced withFilter, which is always non-strict, no matter the strictness of the collection. The following example shows List with both methods on Scala 2.8:

scala> var found = false
found: Boolean = false

scala> List.range(1,10).filter(_ % 2 == 1 && !found).foreach(x => if (x == 5) found = true else println(x))
1
3
7
9

scala> found = false
found: Boolean = false

scala> List.range(1,10).withFilter(_ % 2 == 1 && !found).foreach(x => if (x == 5) found = true else println(x))
1
3

This produces the result most people expect, without changing how filter behaves. As a side note, Range was changed from non-strict to strict between Scala 2.7 and Scala 2.8.

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    die("Database selection failed: " . mysqli_error($connection));
}

You got the order of the arguments to mysqli_select_db() backwards. And mysqli_error() requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.

Note also that with mysqli you can specify the DB in mysqli_connect():

$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
  die("Database connection failed: " . mysqli_connect_error();
}

You must use mysqli_connect_error(), not mysqli_error(), to get the error from mysqli_connect(), since the latter requires you to supply a valid connection.

You can't truly do it in "standard" C, because the size of an int and of a char aren't fixed. Let's say you are using a compiler under Windows or Linux on an intel PC...

int i = 5;
char a = ((char*)&i)[0];
char b = ((char*)&i)[1];

Remember of endianness of your machine! And that int are "normally" 32 bits, so 4 chars!

But you probably meant "i want to stringify a number", so ignore this response :-)

You can use both with relatively few issues. Twitter Bootstrap uses jQuery 1.7.1 (as of this writing), and I can't think of any reasons why you cannot integrate additional Jquery UI components into your HTML templates.

I've been using a combination of HTML5 Boilerplate & Twitter Bootstrap built at Initializr.com. This combines two awesome starter templates into one great starter project. Check out the details at http://html5boilerplate.com/ and http://www.initializr.com/ Or to get started right away, go to http://www.initializr.com/, click the "Bootstrap 2" button, and click "Download It". This will give you all the js and css you need to get started.

And don't be scared off by HTML5 and CSS3. Initializr and HTML5 Boilerplate include polyfills and IE specific code that will allow all features to work in IE 6, 7 8, and 9.

The use of LESS in Twitter Bootstrap is also optional. They use LESS to compile all the CSS that is used by Bootstrap, but if you just want to override or add your own styles, they provide an empty css file for that purpose.

There is also a blank js file (script.js) for you to add custom code. This is where you would add your handlers or selectors for additional jQueryUI components.

The error happens because of you are trying to map a numeric vector to data in geom_errorbar: GVW[1:64,3]. ggplot only works with data.frame.

In general, you shouldn't subset inside ggplot calls. You are doing so because your standard errors are stored in four separate objects. Add them to your original data.frame and you will be able to plot everything in one call.

Here with a dplyr solution to summarise the data and compute the standard error beforehand.

library(dplyr)
d <- GVW %>% group_by(Genotype,variable) %>%
    summarise(mean = mean(value),se = sd(value) / sqrt(n()))

ggplot(d, aes(x = variable, y = mean, fill = Genotype)) + 
  geom_bar(position = position_dodge(), stat = "identity", 
      colour="black", size=.3) +
  geom_errorbar(aes(ymin = mean - se, ymax = mean + se), 
      size=.3, width=.2, position=position_dodge(.9)) +
  xlab("Time") +
  ylab("Weight [g]") +
  scale_fill_hue(name = "Genotype", breaks = c("KO", "WT"), 
      labels = c("Knock-out", "Wild type")) +
  ggtitle("Effect of genotype on weight-gain") +
  scale_y_continuous(breaks = 0:20*4) +
  theme_bw()

If you don't need the leading and trailing spaces :

str.Trim().Length

template <typename T> bool IsInVector(const T & what, const std::vector<T> & vec)
{
    return std::find(vec.begin(),vec.end(),what)!=vec.end();
}

You can use

df <- read.csv("filename.csv", header=TRUE)

# To loop each column
for (i in 1:ncol(df))
    {
    dosomething(df[,i])
    }
# To loop each row
for (i in 1:nrow(df))
    {
    dosomething(df[i,])
    }

Also, you may want to have a look to the apply function (type ?apply or help(apply))if you want to use the same function on each row/column

If the number is stored in a string (which it would be if typed by a user), you can use atoi() to convert it to an integer.

An integer can be assigned directly to a character. A character is different mostly just because how it is interpreted and used.

char c = atoi("61");

function alphaOnly(event) {
  var key = event.keyCode;
  return ((key >= 65 && key <= 90) || key == 8);
};

or

function lettersOnly(evt) {
       evt = (evt) ? evt : event;
       var charCode = (evt.charCode) ? evt.charCode : ((evt.keyCode) ? evt.keyCode :
          ((evt.which) ? evt.which : 0));
       if (charCode > 31 && (charCode < 65 || charCode > 90) &&
          (charCode < 97 || charCode > 122)) {
          alert("Enter letters only.");
          return false;
       }
       return true;
     }

If you're simply trying to scroll to the specified element, you can use the scrollIntoView method of the Element. Here's an example :

$target.get(0).scrollIntoView();

It seems that cygstart/runas does not properly handle "$@" and thus commands that have arguments containing spaces (and perhaps other shell meta-characters -- I didn't check) will not work correctly.

I decided to just write a small sudo script that works by writing a temporary script that does the parameters correctly.

#! /bin/bash

# If already admin, just run the command in-line.
# This works on my Win10 machine; dunno about others.
if id -G | grep -q ' 544 '; then
   "$@"
   exit $?
fi

# cygstart/runas doesn't handle arguments with spaces correctly so create
# a script that will do so properly.
tmpfile=$(mktemp /tmp/sudo.XXXXXX)
echo "#! /bin/bash" >>$tmpfile
echo "export PATH=\"$PATH\"" >>$tmpfile
echo "$1 \\" >>$tmpfile
shift
for arg in "$@"; do
  qarg=`echo "$arg" | sed -e "s/'/'\\\\\''/g"`
  echo "  '$qarg' \\" >>$tmpfile
done
echo >>$tmpfile

# cygstart opens a new window which vanishes as soon as the command is complete.
# Give the user a chance to see the output.
echo "echo -ne '\n$0: press <enter> to close window... '" >>$tmpfile
echo "read enter" >>$tmpfile

# Clean up after ourselves.
echo "rm -f $tmpfile" >>$tmpfile

# Do it as Administrator.
cygstart --action=runas /bin/bash $tmpfile

When one gets the error 'sub-query returns more than 1 row', the database is actually telling you that there is an unresolvable circular reference. It's a bit like using a spreadsheet and saying cell A1 = B1 and then saying B1 = A1. This error is typically associated with a scenario where one needs to have a double nested sub-query. I would recommend you look up a thing called a 'cross-tab query' this is the type of query one normally needs to solve this problem. It's basically an outer join (left or right) nested inside a sub-query or visa versa. One can also solve this problem with a double join (also considered to be a type of cross-tab query) such as below:

CREATE DEFINER=`root`@`localhost` PROCEDURE `SP_GET_VEHICLES_IN`(
    IN P_email VARCHAR(150),
    IN P_credentials VARCHAR(150)
)
BEGIN
    DECLARE V_user_id INT(11);
    SET V_user_id = (SELECT user_id FROM users WHERE email = P_email AND credentials = P_credentials LIMIT 1);
    SELECT vehicles_in.vehicle_id, vehicles_in.make_id, vehicles_in.model_id, vehicles_in.model_year,
    vehicles_in.registration, vehicles_in.date_taken, make.make_label, model.model_label
    FROM make
    LEFT OUTER JOIN vehicles_in ON vehicles_in.make_id = make.make_id
    LEFT OUTER JOIN model ON model.make_id = make.make_id AND vehicles_in.model_id = model.model_id
    WHERE vehicles_in.user_id = V_user_id;
END

In the code above notice that there are three tables in amongst the SELECT clause and these three tables show up after the FROM clause and after the two LEFT OUTER JOIN clauses, these three tables must be distinct amongst the FROM and LEFT OUTER JOIN clauses to be syntactically correct.

It is noteworthy that this is a very important construct to know as a developer especially if you're writing periodical report queries and it's probably the most important skill for any complex cross referencing, so all developers should study these constructs (cross-tab and double join).

Another thing I must warn about is: If you are going to use a cross-tab as a part of a working system and not just a periodical report, you must check the record count and reconfigure the join conditions until the minimum records are returned, otherwise large tables and cross-tabs can grind your server to a halt. Hope this helps.

You use separator when you are building a file path. So in unix the separator is /. So if you wanted to build the unix path /var/temp you would do it like this:

String path = File.separator + "var"+ File.separator + "temp"

You use the pathSeparator when you are dealing with a list of files like in a classpath. For example, if your app took a list of jars as argument the standard way to format that list on unix is: /path/to/jar1.jar:/path/to/jar2.jar:/path/to/jar3.jar

So given a list of files you would do something like this:

String listOfFiles = ...
String[] filePaths = listOfFiles.split(File.pathSeparator);

Experienced this when I downloaded a page for offline view.

I just had to remove the integrity="*****" and crossorigin="anonymous" attributes from all <link> and <script> tags

This is potentially a better option and faster than ERB: https://github.com/dewski/json_builder

I'm not sure this will help you to much by I once needed a batch file to open a game, the .exe was in a folder with blanks (duh!) and I tried : START "C:\Fold 1\fold 2\game.exe" and START C:\Fold 1\fold 2\game.exe - None worked, then I tried

   START C:\"Fold 1"\"fold 2"\game.exe and it worked 

Hope it helps :)

Here's a code excerpt we're using in our app to set request headers. You'll note we set the CONTENT_TYPE header only on a POST or PUT, but the general method of adding headers (via a request interceptor) is used for GET as well.

/**
 * HTTP request types
 */
public static final int POST_TYPE   = 1;
public static final int GET_TYPE    = 2;
public static final int PUT_TYPE    = 3;
public static final int DELETE_TYPE = 4;

/**
 * HTTP request header constants
 */
public static final String CONTENT_TYPE         = "Content-Type";
public static final String ACCEPT_ENCODING      = "Accept-Encoding";
public static final String CONTENT_ENCODING     = "Content-Encoding";
public static final String ENCODING_GZIP        = "gzip";
public static final String MIME_FORM_ENCODED    = "application/x-www-form-urlencoded";
public static final String MIME_TEXT_PLAIN      = "text/plain";

private InputStream performRequest(final String contentType, final String url, final String user, final String pass,
    final Map<String, String> headers, final Map<String, String> params, final int requestType) 
            throws IOException {

    DefaultHttpClient client = HTTPClientFactory.newClient();

    client.getParams().setParameter(HttpProtocolParams.USER_AGENT, mUserAgent);

    // add user and pass to client credentials if present
    if ((user != null) && (pass != null)) {
        client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(user, pass));
    }

    // process headers using request interceptor
    final Map<String, String> sendHeaders = new HashMap<String, String>();
    if ((headers != null) && (headers.size() > 0)) {
        sendHeaders.putAll(headers);
    }
    if (requestType == HTTPRequestHelper.POST_TYPE || requestType == HTTPRequestHelper.PUT_TYPE ) {
        sendHeaders.put(HTTPRequestHelper.CONTENT_TYPE, contentType);
    }
    // request gzip encoding for response
    sendHeaders.put(HTTPRequestHelper.ACCEPT_ENCODING, HTTPRequestHelper.ENCODING_GZIP);

    if (sendHeaders.size() > 0) {
        client.addRequestInterceptor(new HttpRequestInterceptor() {

            public void process(final HttpRequest request, final HttpContext context) throws HttpException,
                IOException {
                for (String key : sendHeaders.keySet()) {
                    if (!request.containsHeader(key)) {
                        request.addHeader(key, sendHeaders.get(key));
                    }
                }
            }
        });
    }

It seems you need DataFrame.var:

Normalized by N-1 by default. This can be changed using the ddof argument

var1 = credit_card.var()

Sample:

#random dataframe
np.random.seed(100)
credit_card = pd.DataFrame(np.random.randint(10, size=(5,5)), columns=list('ABCDE'))
print (credit_card)
   A  B  C  D  E
0  8  8  3  7  7
1  0  4  2  5  2
2  2  2  1  0  8
3  4  0  9  6  2
4  4  1  5  3  4

var1 = credit_card.var()
print (var1)
A     8.8
B    10.0
C    10.0
D     7.7
E     7.8
dtype: float64

var2 = credit_card.var(axis=1)
print (var2)
0     4.3
1     3.8
2     9.8
3    12.2
4     2.3
dtype: float64

If need numpy solutions with numpy.var:

print (np.var(credit_card.values, axis=0))
[ 7.04  8.    8.    6.16  6.24]

print (np.var(credit_card.values, axis=1))
[ 3.44  3.04  7.84  9.76  1.84]

Differences are because by default ddof=1 in pandas, but you can change it to 0:

var1 = credit_card.var(ddof=0)
print (var1)
A    7.04
B    8.00
C    8.00
D    6.16
E    6.24
dtype: float64

var2 = credit_card.var(ddof=0, axis=1)
print (var2)
0    3.44
1    3.04
2    7.84
3    9.76
4    1.84
dtype: float64

Don't use CREATE TYPE to return a polymorphic result. Use and abuse the RECORD type instead. Check it out:

CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE 
  ret RECORD;
BEGIN
  -- Arbitrary expression to change the first parameter
  IF LENGTH(a) < LENGTH(b) THEN
      SELECT TRUE, a || b, 'a shorter than b' INTO ret;
  ELSE
      SELECT FALSE, b || a INTO ret;
  END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;

Pay attention to the fact that it can optionally return two or three columns depending on the input.

test=> SELECT test_ret('foo','barbaz');
             test_ret             
----------------------------------
 (t,foobarbaz,"a shorter than b")
(1 row)

test=> SELECT test_ret('barbaz','foo');
             test_ret             
----------------------------------
 (f,foobarbaz)
(1 row)

This does wreak havoc on code, so do use a consistent number of columns, but it's ridiculously handy for returning optional error messages with the first parameter returning the success of the operation. Rewritten using a consistent number of columns:

CREATE FUNCTION test_ret(a TEXT, b TEXT) RETURNS RECORD AS $$
DECLARE 
  ret RECORD;
BEGIN
  -- Note the CASTING being done for the 2nd and 3rd elements of the RECORD
  IF LENGTH(a) < LENGTH(b) THEN
      ret := (TRUE, (a || b)::TEXT, 'a shorter than b'::TEXT);
  ELSE
      ret := (FALSE, (b || a)::TEXT, NULL::TEXT);
   END IF;
RETURN ret;
END;$$ LANGUAGE plpgsql;

Almost to epic hotness:

test=> SELECT test_ret('foobar','bar');
   test_ret    
----------------
 (f,barfoobar,)
(1 row)

test=> SELECT test_ret('foo','barbaz');
             test_ret             
----------------------------------
 (t,foobarbaz,"a shorter than b")
(1 row)

But how do you split that out in to multiple rows so that your ORM layer of choice can convert the values in to your language of choice's native data types? The hotness:

test=> SELECT a, b, c FROM test_ret('foo','barbaz') AS (a BOOL, b TEXT, c TEXT);
 a |     b     |        c         
---+-----------+------------------
 t | foobarbaz | a shorter than b
(1 row)

test=> SELECT a, b, c FROM test_ret('foobar','bar') AS (a BOOL, b TEXT, c TEXT);
 a |     b     | c 
---+-----------+---
 f | barfoobar | 
(1 row)

This is one of the coolest and most underused features in PostgreSQL. Please spread the word.

Not sure where you get your legends from but:

Submit button with <button>

As with:

<button type="submit">(html content)</button>

IE6 will submit all text for this button between the tags, other browsers will only submit the value. Using <button> gives you more layout freedom over the design of the button. In all its intents and purposes, it seemed excellent at first, but various browser quirks make it hard to use at times.

In your example, IE6 will send text to the server, while most other browsers will send nothing. To make it cross-browser compatible, use <button type="submit" value="text">text</button>. Better yet: don't use the value, because if you add HTML it becomes rather tricky what is received on server side. Instead, if you must send an extra value, use a hidden field.

Button with <input>

As with:

<input type="button" />

By default, this does next to nothing. It will not even submit your form. You can only place text on the button and give it a size and a border by means of CSS. Its original (and current) intent was to execute a script without the need to submit the form to the server.

Normal submit button with <input>

As with:

<input type="submit" />

Like the former, but actually submits the surrounding form.

Image submit button with <input>

As with:

<input type="image" />

Like the former (submit), it will also submit a form, but you can use any image. This used to be the preferred way to use images as buttons when a form needed submitting. For more control, <button> is now used. This can also be used for server side image maps but that's a rarity these days. When you use the usemap-attribute and (with or without that attribute), the browser will send the mouse-pointer X/Y coordinates to the server (more precisely, the mouse-pointer location inside the button of the moment you click it). If you just ignore these extras, it is nothing more than a submit button disguised as an image.

There are some subtle differences between browsers, but all will submit the value-attribute, except for the <button> tag as explained above.

For question 1 use os.getcwd() # get working dir and os.chdir(r'D:\Steam\steamapps\common') # set working dir

I recommend using sys.argv[0] for question 2 because sys.argv is immutable and therefore always returns the current file (module object path) and not affected by os.chdir(). Also you can do like this:

import os
this_py_file = os.path.realpath(__file__)

# vvv Below comes your code vvv #

but that snippet and sys.argv[0] will not work or will work wierd when compiled by PyInstaller because magic properties are not set in __main__ level and sys.argv[0] is the way your exe was called (means that it becomes affected by the working dir).

use,

delete req.session.yoursessionname;

s[0:"s".index("&")]

what does this do:

• take a slice from the string starting at index 0, up to, but not including the index of &in the string.

You could use the following:

var json = @Html.Raw(Json.Encode(@Model.CollegeInformationlist));

This would output the following (without seeing your model I've only included one field):

<script>
    var json = [{"State":"a state"}];   
</script>

Working Fiddle

AspNetCore

AspNetCore uses Json.Serialize intead of Json.Encode

var json = @Html.Raw(Json.Serialize(@Model.CollegeInformationlist));

MVC 5/6

You can use Newtonsoft for this:

    @Html.Raw(Newtonsoft.Json.JsonConvert.SerializeObject(Model, 
Newtonsoft.Json.Formatting.Indented))

This gives you more control of the json formatting i.e. indenting as above, camelcasing etc.

Using CMD you can run your python scripts as long as the installed python is added to the path with the following line:

C: \ Python27;

The (27) is example referring to version 2.7, add as per your version.

Path to system path:

Control Panel => System and Security => System => Advanced Settings => Advanced => Environment Variables.

Under "User Variables," append the PATH variable to the path of the Python installation directory (As above).

Once this is done, you can open a CMD where your scripts are saved, or manually navigate through the CMD.

To run the script enter:

C: \ User \ X \ MyScripts> python ScriptName.py

See excerpt from official documentation for containment option:

containment

Default: false

Constrains dragging to within the bounds of the specified element or region.
Multiple types supported:

• Selector: The draggable element will be contained to the bounding box of the first element found by the selector. If no element is found, no containment will be set.
• Element: The draggable element will be contained to the bounding box of this element.
• String: Possible values: "parent", "document", "window".
• Array: An array defining a bounding box in the form [ x1, y1, x2, y2 ].

Code examples:
Initialize the draggable with the containment option specified:

$( ".selector" ).draggable({
    containment: "parent" 
}); 

Get or set the containment option, after initialization:

// Getter
var containment = $( ".selector" ).draggable( "option", "containment" );
// Setter
$( ".selector" ).draggable( "option", "containment", "parent" );

Look at shutil in the Python docs, specifically the copytree command.

If the destination directory already exists, try:

shutil.copytree(source, destination, dirs_exist_ok=True)

Under "Start" enter "environment" in the search field. That will list the option to change the system variables directly in the start menu.

Assuming you do not have local commits,

git diff origin/master

I want to give my resolution, it work when i replace the line [session = tf.Session()] with [sess = tf.InteractiveSession()]. Hope this will be useful to others.

OUTPUT :

Alternatively, if you want to get the IP address of whichever interface is used to connect to the network without having to know its name, you can use this:

import socket
def get_ip_address():
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    s.connect(("8.8.8.8", 80))
    return s.getsockname()[0]

I know it's a little different than your question, but others may arrive here and find this one more useful. You do not have to have a route to 8.8.8.8 to use this. All it is doing is opening a socket, but not sending any data.

Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.

Update:

It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.

I just added the existing framework folder manually into the project navigator. Worked for me.

So what will happen if two threads attack a volatile primitive variable at same time?

Usually each one can increment the value. However sometime, both will update the value at the same time and instead of incrementing by 2 total, both thread increment by 1 and only 1 is added.

Does this mean that whosoever takes lock on it, that will be setting its value first.

There is no lock. That is what synchronized is for.

And in if meantime, some other thread comes up and read old value while first thread was changing its value, then doesn't new thread will read its old value?

Yes,

What is the difference between Atomic and volatile keyword?

AtomicXxxx wraps a volatile so they are basically same, the difference is that it provides higher level operations such as CompareAndSwap which is used to implement increment.

AtomicXxxx also supports lazySet. This is like a volatile set, but doesn't stall the pipeline waiting for the write to complete. It can mean that if you read a value you just write you might see the old value, but you shouldn't be doing that anyway. The difference is that setting a volatile takes about 5 ns, bit lazySet takes about 0.5 ns.

If you install Notepad++ on Linux system by wine (In my case desktop Ubuntu 14.04-LTS_X64) the file "shortcuts.xml" is under :

Thanks to Harrison and all that have suggestions for that isssue.

Append vs Extend

With append you can append a single element that will extend the list:

>>> a = [1,2]
>>> a.append(3)
>>> a
[1,2,3]

If you want to extend more than one element you should use extend, because you can only append one elment or one list of element:

>>> a.append([4,5])
>>> a
>>> [1,2,3,[4,5]]

So that you get a nested list

Instead with extend, you can extend a single element like this

>>> a = [1,2]
>>> a.extend([3])
>>> a
[1,2,3]

Or, differently, from append, extend more elements in one time without nesting the list into the original one (that's the reason of the name extend)

>>> a.extend([4,5,6])
>>> a
[1,2,3,4,5,6]

Adding one element with both methods

Both append and extend can add one element to the end of the list, though append is simpler.

append 1 element

>>> x = [1,2]
>>> x.append(3)
>>> x
[1,2,3]

extend one element

>>> x = [1,2]
>>> x.extend([3])
>>> x
[1,2,3]

Adding more elements... with different results

If you use append for more than one element, you have to pass a list of elements as arguments and you will obtain a NESTED list!

>>> x = [1,2]
>>> x.append([3,4])
>>> x
[1,2,[3,4]]

With extend, instead, you pass a list as an argument, but you will obtain a list with the new element that is not nested in the old one.

>>> z = [1,2] 
>>> z.extend([3,4])
>>> z
[1,2,3,4]

So, with more elements, you will use extend to get a list with more items. However, appending a list will not add more elements to the list, but one element that is a nested list as you can clearly see in the output of the code.

Maven advantages over ant are quite a few. I try to summarize them here.

Convention over Configuration
Maven uses a distinctive approach for the project layout and startup, that makes easy to just jump in a project. Usually it only takes the checkount and the maven command to get the artifacts of the project.

Project Modularization
Project conventions suggest (or better, force) the developer to modularize the project. Instead of a monolithic project you are often forced to divide your project in smaller sub components, which make it easier debug and manage the overall project structure

Dependency Management and Project Lifecycle
Overall, with a good SCM configuration and an internal repository, the dependency management is quite easy, and you are again forced to think in terms of Project Lifecycle - component versions, release management and so on. A little more complex than the ant something, but again, an improvement in quality of the project.

What is wrong with maven?
Maven is not easy. The build cycle (what gets done and when) is not so clear within the POM. Also, some issue arise with the quality of components and missing dependencies in public repositories.
The best approach (to me) is to have an internal repository for caching (and keeping) dependencies around, and to apply to release management of components. For projects bigger than the sample projects in a book, you will thank maven before or after

I've created a "lazy load" plugin which might help. Here is the a possible way to get the job done with it in your case:

$('img').lazyloadanything({
    'onLoad': function(e, LLobj) {
        var $img = LLobj.$element;
        var src = $img.attr('data-src');
        $img.css('background-image', 'url("'+src+'")');
    }
});

It is simple like maosmurf's example but still gives you the "lazy load" functionality of event firing when the element comes into view.

This is a very good and reliable solution: http://vinsol.com/blog/2014/10/01/handling-back-button-press-inside-fragments/

The guy has made an abstract fragment that handles the backPress behaviour and is switching between the active fragments using the strategy pattern.

For some of you there maybe a little drawback in the abstract class...

Shortly, the solution from the link goes like this:

// Abstract Fragment handling the back presses

public abstract class BackHandledFragment extends Fragment {
    protected BackHandlerInterface backHandlerInterface;
    public abstract String getTagText();
    public abstract boolean onBackPressed();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if(!(getActivity()  instanceof BackHandlerInterface)) {
            throw new ClassCastException("Hosting activity must implement BackHandlerInterface");
        } else {
            backHandlerInterface = (BackHandlerInterface) getActivity();
        }
    }

    @Override
    public void onStart() {
        super.onStart();

        // Mark this fragment as the selected Fragment.
        backHandlerInterface.setSelectedFragment(this);
    }

    public interface BackHandlerInterface {
        public void setSelectedFragment(BackHandledFragment backHandledFragment);
    }
}   

And usage in the activity:

// BASIC ACTIVITY CODE THAT LETS ITS FRAGMENT UTILIZE onBackPress EVENTS 
// IN AN ADAPTIVE AND ORGANIZED PATTERN USING BackHandledFragment

public class TheActivity extends FragmentActivity implements BackHandlerInterface {
    private BackHandledFragment selectedFragment;

    @Override
    public void onBackPressed() {
        if(selectedFragment == null || !selectedFragment.onBackPressed()) {
            // Selected fragment did not consume the back press event.
            super.onBackPressed();
        }
    }

    @Override
    public void setSelectedFragment(BackHandledFragment selectedFragment) {
        this.selectedFragment = selectedFragment;
    }
}

You can make a deep copy with serialization without creating files.

Your object you wish to deep copy will need to implement serializable. If the class isn't final or can't be modified, extend the class and implement serializable.

Convert your class to a stream of bytes:

ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(object);
oos.flush();
oos.close();
bos.close();
byte[] byteData = bos.toByteArray();

Restore your class from a stream of bytes:

ByteArrayInputStream bais = new ByteArrayInputStream(byteData);
(Object) object = (Object) new ObjectInputStream(bais).readObject();

If you can't be bothered to remember what argument position is for what and you want do something like a ruby argument hash. You can use one argument to pass in a string and then regex that string into an options hash.

namespace :dummy_data do
  desc "Tests options hash like arguments"
  task :test, [:options] => :environment do |t, args|
    arg_options = args[:options] || '' # nil catch incase no options are provided
    two_d_array = arg_options.scan(/\W*(\w*): (\w*)\W*/)
    puts two_d_array.to_s + ' # options are regexed into a 2d array'
    string_key_hash = two_d_array.to_h
    puts string_key_hash.to_s + ' # options are in a hash with keys as strings'
    options = two_d_array.map {|p| [p[0].to_sym, p[1]]}.to_h
    puts options.to_s + ' # options are in a hash with symbols'
    default_options = {users: '50', friends: '25', colour: 'red', name: 'tom'}
    options = default_options.merge(options)
    puts options.to_s + ' # default option values are merged into options'
  end
end

And on the command line you get.

$ rake dummy_data:test["users: 100 friends: 50 colour: red"]
[["users", "100"], ["friends", "50"], ["colour", "red"]] # options are regexed into a 2d array
{"users"=>"100", "friends"=>"50", "colour"=>"red"} # options are in a hash with keys as strings
{:users=>"100", :friends=>"50", :colour=>"red"} # options are in a hash with symbols
{:users=>"100", :friends=>"50", :colour=>"red", :name=>"tom"} # default option values are merged into options

Bozo sort is a related algorithm that checks if the list is sorted and, if not, swaps two items at random. It has the same best and worst case performances, but I would intuitively expect the average case to be longer than Bogosort. It's hard to find (or produce) any data on performance of this algorithm.

I had this same error with ADT22. Resolved it checking "Android Private Libraries" in properties -> Java build path -> Order and export. If you are using any library projects, the same should be done for them as well.

SQL Server 2012 and up support LAG / LEAD functions to access the previous or subsequent row. SQL Server 2005 does not support this (in SQL2005 you need a join or something else).

A SQL 2012 example on this data

/* Prepare */
select * into #tmp
from
(
    select 2  as rowint,      23 as Value
    union select 3,       45
    union select 17,      10
    union select 9,       0
) x


/* The SQL 2012 query */
select rowInt, Value, LEAD(value) over (order by rowInt) - Value  
from #tmp

LEAD(value) will return the value of the next row in respect to the given order in "over" clause.

I had this or a similar problem after installing Tomcat.

The other answers didn't quite work, but got me on the right path. I answered this at https://stackoverflow.com/a/20762179/3128838 after discovering a YouTube video showing the exact problem I was having.

Another notable (good) difference about PDO is that it's PDO::quote() method automatically adds the enclosing quotes, whereas mysqli::real_escape_string() (and similars) don't:

PDO::quote() places quotes around the input string (if required) and escapes special characters within the input string, using a quoting style appropriate to the underlying driver.

2. See MERGE CHANGES in sidebar.
3. Those files have merge conflicts.

If I could suggest setting up your dataframes like this (auto-indexing):

df = pd.DataFrame({'a':[np.nan, 1, 2], 'b':[4, 5, 6]})

then you can set up your s1 and s2 values thus (using shape() to return the number of rows from df):

s = pd.DataFrame({'s1':[5]*df.shape[0], 's2':[6]*df.shape[0]})

then the result you want is easy:

display (df.merge(s, left_index=True, right_index=True))

Alternatively, just add the new values to your dataframe df:

df = pd.DataFrame({'a':[nan, 1, 2], 'b':[4, 5, 6]})
df['s1']=5
df['s2']=6
display(df)

Both return:

     a  b  s1  s2
0  NaN  4   5   6
1  1.0  5   5   6
2  2.0  6   5   6

If you have another list of data (instead of just a single value to apply), and you know it is in the same sequence as df, eg:

s1=['a','b','c']

then you can attach this in the same way:

df['s1']=s1

returns:

     a  b s1
0  NaN  4  a
1  1.0  5  b
2  2.0  6  c

You can leave date_add function.

TWO DECIMALS

result = Math.round(x * 1000) / 1000      // result .123

EOF indicates "end of file". A newline (which is what happens when you press enter) isn't the end of a file, it's the end of a line, so a newline doesn't terminate this loop.

The code isn't wrong[*], it just doesn't do what you seem to expect. It reads to the end of the input, but you seem to want to read only to the end of a line.

The value of EOF is -1 because it has to be different from any return value from getchar that is an actual character. So getchar returns any character value as an unsigned char, converted to int, which will therefore be non-negative.

If you're typing at the terminal and you want to provoke an end-of-file, use CTRL-D (unix-style systems) or CTRL-Z (Windows). Then after all the input has been read, getchar() will return EOF, and hence getchar() != EOF will be false, and the loop will terminate.

[*] well, it has undefined behavior if the input is more than LONG_MAX characters due to integer overflow, but we can probably forgive that in a simple example.

Try this

<div class="row">
    <div class="col-xs-2 col-xs-offset-5"></div>
</div>

You can use other col as well like col-md-2, etc.

This formula will do the job:

=INDEX(G:G,MATCH(FALSE,ISERROR(SEARCH(H1,G:G)),0)+3)

you need to enter it as an array formula, i.e. press Ctrl-Shift-Enter. It assumes that the substring you're searching for is in cell H1.

This code removes repetition of characters i.e, if the input is aaabbcc then the output will be abc. (the array must be sorted for this code to work)

cin >> s;
ans = "";
ans += s[0];
for(int i = 1;i < s.length();++i)
if(s[i] != s[i-1])
    ans += s[i];
cout << ans << endl;

I believe you can do this using a cast:

float f_val = 3.6f;
int i_val = (int) f_val;

You may be able to replace the:

VirtualHost ipaddress:443

with

VirtualHost *:443

You probably need todo this on all of your virt hosts.

It will probably clear up that message. Let the ServerName directive worry about routing the message request.

Again, you may not be able to do this if you have multiple ip's aliases to the same machine.

If you need not equal object condition use cross join sequences:

var query = from obj1 in set1
from obj2 in set2
where obj1.key1 == obj2.key2 && obj1.key3.contains(obj2.key5) [...conditions...]

In case if you were to pass the image as part of JSON along with other attributes, you can use the below snippet.

headers = {'Content-type': 'application/json', 'Accept': 'text/plain'}
  
payload = json.dumps({"image": im_b64, "other_key": "value"})
response = requests.post(api, data=payload, headers=headers)

The accepted answer here indeed makes a json from a form, but the json contents is really a string with url-encoded contents.

To make a more realistic json POST, use some solution from Serialize form data to JSON to make formToJson function and add contentType: 'application/json;charset=UTF-8' to the jQuery ajax call parameters.

$.ajax({
    url: 'test.php',
    type: "POST",
    dataType: 'json',
    data: formToJson($("form")),
    contentType: 'application/json;charset=UTF-8',
    ...
})

If you want to use default mailtrip.io you don't need to modify mail.php file.

1. Create account on mailtrip.io
2. Go to Inboxes > My Inbox > SMTP Settings > Integration Laravel
3. Modify .env file and replace all nulls of correct credentials:

MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

4. Run:

php artisan config:cache

In most contexts where double values are used, calculations will have a certain amount of uncertainty. The difference between 1.33333333333333300 and 1.33333333333333399 may be less than the amount of uncertainty that exists in the calculations. Displaying the value of "2/3 + 2/3" as "1.33333333333333" is apt to be more meaningful than displaying it as "1.33333333333333319", since the latter display implies a level of precision that doesn't really exist.

In the debugger, however, it is important to uniquely indicate the value held by a variable, including essentially-meaningless bits of precision. It would be very confusing if a debugger displayed two variables as holding the value "1.333333333333333" when one of them actually held 1.33333333333333319 and the other held 1.33333333333333294 (meaning that, while they looked the same, they weren't equal). The extra precision shown by the debugger isn't apt to represent a numerically-correct calculation result, but indicates how the code will interpret the values held by the variables.

The Host property will return the domain name you used when accessing the site. So, in your development environment, since you're requesting

It's returning localhost. You can break apart your URL like so:

Protocol: http
Host: localhost
Port: 950

This extension helps you to constraint a UIVIew to its superview and superview+safeArea:

extension UIView {

    ///Constraints a view to its superview
    func constraintToSuperView() {
        guard let superview = superview else { return }
        translatesAutoresizingMaskIntoConstraints = false

        topAnchor.constraint(equalTo: superview.topAnchor).isActive = true
        leftAnchor.constraint(equalTo: superview.leftAnchor).isActive = true
        bottomAnchor.constraint(equalTo: superview.bottomAnchor).isActive = true
        rightAnchor.constraint(equalTo: superview.rightAnchor).isActive = true
    }

    ///Constraints a view to its superview safe area
    func constraintToSafeArea() {
        guard let superview = superview else { return }
        translatesAutoresizingMaskIntoConstraints = false

        topAnchor.constraint(equalTo: superview.safeAreaLayoutGuide.topAnchor).isActive = true
        leftAnchor.constraint(equalTo: superview.safeAreaLayoutGuide.leftAnchor).isActive = true
        bottomAnchor.constraint(equalTo: superview.safeAreaLayoutGuide.bottomAnchor).isActive = true
        rightAnchor.constraint(equalTo: superview.safeAreaLayoutGuide.rightAnchor).isActive = true
    }

}

change this {% if loop.counter == 1 %} to {% if forloop.counter == 1 %} {#your code here#} {%endfor%}

and this from {{ user }} {{loop.counter}} to {{ user }} {{forloop.counter}}

AndroidStudio is alpha version for now. So you have to edit gradle build script files by yourself. Add next lines to your build.gradle

android {

    signingConfigs {

        release {

            storeFile file('android.keystore')
            storePassword "pwd"
            keyAlias "alias"
            keyPassword "pwd"
        }
    }

    buildTypes {

       release {

           signingConfig signingConfigs.release
       }
    }
}

To actually run your application at emulator or device run gradle installDebug or gradle installRelease.

You can create helloworld project from AndroidStudio wizard to see what structure of gradle files is needed. Or export gradle files from working eclipse project. Also this series of articles are helpfull http://blog.stylingandroid.com/archives/1872#more-1872

Yes there is, since setState works in an asynchronous way. That means after calling setState the this.state variable is not immediately changed. so if you want to perform an action immediately after setting state on a state variable and then return a result, a callback will be useful

Consider the example below

....
changeTitle: function changeTitle (event) {
  this.setState({ title: event.target.value });
  this.validateTitle();
},
validateTitle: function validateTitle () {
  if (this.state.title.length === 0) {
    this.setState({ titleError: "Title can't be blank" });
  }
},
....

The above code may not work as expected since the title variable may not have mutated before validation is performed on it. Now you may wonder that we can perform the validation in the render() function itself but it would be better and a cleaner way if we can handle this in the changeTitle function itself since that would make your code more organised and understandable

In this case callback is useful

....
changeTitle: function changeTitle (event) {
  this.setState({ title: event.target.value }, function() {
    this.validateTitle();
  });

},
validateTitle: function validateTitle () {
  if (this.state.title.length === 0) {
    this.setState({ titleError: "Title can't be blank" });
  }
},
....

Another example will be when you want to dispatch and action when the state changed. you will want to do it in a callback and not the render() as it will be called everytime rerendering occurs and hence many such scenarios are possible where you will need callback.

Another case is a API Call

A case may arise when you need to make an API call based on a particular state change, if you do that in the render method, it will be called on every render onState change or because some Prop passed down to the Child Component changed.

In this case you would want to use a setState callback to pass the updated state value to the API call

....
changeTitle: function (event) {
  this.setState({ title: event.target.value }, () => this.APICallFunction());
},
APICallFunction: function () {
  // Call API with the updated value
}
....

The top voted answer is deprecated in Bootstrap 3.3 and will be removed in v4. Try this instead:

JavaScript:

// Fill modal with content from link href
$("#myModal").on("show.bs.modal", function(e) {
    var link = $(e.relatedTarget);
    $(this).find(".modal-body").load(link.attr("href"));
});

Html (Based on the official example. Note that for Bootstrap 3.* we set data-remote="false" to disable the deprecated Bootstrap load function):

<!-- Link trigger modal -->

In MacOS Catalina 10.15.5 the .npmrc file path can be found at

/Users/<user-name>/.npmrc

Open in it in (for first time users, create a new file) any editor and copy-paste your token. Save it.

You are ready to go.

Note: As mentioned by @oligofren, the command npm config ls -l will npm configurations. You will get the .npmrc file from config parameter userconfig

Python3 + Using boto3 API approach.

By using S3.Client.download_fileobj API and Python file-like object, S3 Object content can be retrieved to memory.

Since the retrieved content is bytes, in order to convert to str, it need to be decoded.

import io
import boto3

client = boto3.client('s3')
bytes_buffer = io.BytesIO()
client.download_fileobj(Bucket=bucket_name, Key=object_key, Fileobj=bytes_buffer)
byte_value = bytes_buffer.getvalue()
str_value = byte_value.decode() #python3, default decoding is utf-8

Below example may help,

int main(void)
{
    double **a2d = new double*[5]; 
    /* initializing Number of rows, in this case 5 rows) */
    for (int i = 0; i < 5; i++)
    {
        a2d[i] = new double[3]; /* initializing Number of columns, in this case 3 columns */
    }

    for (int i = 0; i < 5; i++)
    {
        for (int j = 0; j < 3; j++)
        {
            a2d[i][j] = 1; /* Assigning value 1 to all elements */
        }
    }

    for (int i = 0; i < 5; i++)
    {
        for (int j = 0; j < 3; j++)
        {
            cout << a2d[i][j] << endl;  /* Printing all elements to verify all elements have been correctly assigned or not */
        }
    }

    for (int i = 0; i < 5; i++)
        delete[] a2d[i];

    delete[] a2d;


    return 0;
}

You can get a stream from the List and put in in the TreeSet from which you provide a custom comparator that compares id uniquely.

Then if you really need a list you can put then back this collection into an ArrayList.

import static java.util.Comparator.comparingInt;
import static java.util.stream.Collectors.collectingAndThen;
import static java.util.stream.Collectors.toCollection;

...
List<Employee> unique = employee.stream()
                                .collect(collectingAndThen(toCollection(() -> new TreeSet<>(comparingInt(Employee::getId))),
                                                           ArrayList::new));

Given the example:

List<Employee> employee = Arrays.asList(new Employee(1, "John"), new Employee(1, "Bob"), new Employee(2, "Alice"));

It will output:

[Employee{id=1, name='John'}, Employee{id=2, name='Alice'}]

Another idea could be to use a wrapper that wraps an employee and have the equals and hashcode method based with its id:

class WrapperEmployee {
    private Employee e;

    public WrapperEmployee(Employee e) {
        this.e = e;
    }

    public Employee unwrap() {
        return this.e;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        WrapperEmployee that = (WrapperEmployee) o;
        return Objects.equals(e.getId(), that.e.getId());
    }

    @Override
    public int hashCode() {
        return Objects.hash(e.getId());
    }
}

Then you wrap each instance, call distinct(), unwrap them and collect the result in a list.

List<Employee> unique = employee.stream()
                                .map(WrapperEmployee::new)
                                .distinct()
                                .map(WrapperEmployee::unwrap)
                                .collect(Collectors.toList());

In fact, I think you can make this wrapper generic by providing a function that will do the comparison:

public class Wrapper<T, U> {
    private T t;
    private Function<T, U> equalityFunction;

    public Wrapper(T t, Function<T, U> equalityFunction) {
        this.t = t;
        this.equalityFunction = equalityFunction;
    }

    public T unwrap() {
        return this.t;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        @SuppressWarnings("unchecked")
        Wrapper<T, U> that = (Wrapper<T, U>) o;
        return Objects.equals(equalityFunction.apply(this.t), that.equalityFunction.apply(that.t));
    }

    @Override
    public int hashCode() {
        return Objects.hash(equalityFunction.apply(this.t));
    }
}

and the mapping will be:

.map(e -> new Wrapper<>(e, Employee::getId))

As far as I know, the order of the repositories in your pom.xml will also decide the order of the repository access.

As for configuring repositories in settings.xml, I've read that the order of repositories is interestingly enough the inverse order of how the repositories will be accessed.

Here a post where someone explains this curiosity:
http://community.jboss.org/message/576851

as i know there are 4 ways to do that.

var style= document.createElement("style");
(document.head || document.documentElement).appendChild(style);
var rule=':visited {    color: rgb(233, 106, 106) !important;}';

//no 1
style.innerHTML = rule;
//no 2
style.appendChild(document.createTextNode(rule));

//no 3 limited with one group
style.sheet.insertRule(rule);
//no 4 limited too
document.styleSheets[0].insertRule('strong { color: red; }');

//addon
style.sheet.cssRules //list all style
stylesheet.deleteRule(0)  //delete first rule

f(n) belongs to O(n) if exists positive k as f(n)<=k*n

f(n) belongs to T(n) if exists positive k1, k2 as k1*n<=f(n)<=k2*n

try to implement Application_AuthenticateRequest instead of Application_Start.

this method has an instance for HttpContext.Current, unlike Application_Start (which fires very soon in app lifecycle, soon enough to not hold a HttpContext.Current object yet).

hope that helps.

In Server tab of Tomcat configuration in IntelliJ, change JMX port to another number.

Another source of this problem: I found that in Debian 9, the Python httplib2 is hardcoded to insist on TLS v1.0. So any application that uses httplib2 to connect to a server that insists on better security fails with TLSV1_ALERT_PROTOCOL_VERSION.

I fixed it by changing

context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)

to

context = ssl.SSLContext()

in /usr/lib/python3/dist-packages/httplib2/__init__.py .

Debian 10 doesn't have this problem.

You can create files in browser using Blob and URL.createObjectURL. All recent browsers support this.

You can not directly save the file you create, since that would cause massive security problems, but you can provide it as a download link for the user. You can suggest a file name via the download attribute of the link, in browsers that support the download attribute. As with any other download, the user downloading the file will have the final say on the file name though.

var textFile = null,
  makeTextFile = function (text) {
    var data = new Blob([text], {type: 'text/plain'});

    // If we are replacing a previously generated file we need to
    // manually revoke the object URL to avoid memory leaks.
    if (textFile !== null) {
      window.URL.revokeObjectURL(textFile);
    }

    textFile = window.URL.createObjectURL(data);

    // returns a URL you can use as a href
    return textFile;
  };

Here's an example that uses this technique to save arbitrary text from a textarea.

If you want to immediately initiate the download instead of requiring the user to click on a link, you can use mouse events to simulate a mouse click on the link as Lifecube's answer did. I've created an updated example that uses this technique.

  var create = document.getElementById('create'),
    textbox = document.getElementById('textbox');

  create.addEventListener('click', function () {
    var link = document.createElement('a');
    link.setAttribute('download', 'info.txt');
    link.href = makeTextFile(textbox.value);
    document.body.appendChild(link);

    // wait for the link to be added to the document
    window.requestAnimationFrame(function () {
      var event = new MouseEvent('click');
      link.dispatchEvent(event);
      document.body.removeChild(link);
    });

  }, false);

str = (str + '?').replace(list[i] + '?', 'finish');

at is the correct way.

If you don't have the at command in the machine and you also don't have install privilegies on it, you can put something like this on cron (maybe with the crontab command):

* * * 5 * /path/to/comand_to_execute; /usr/bin/crontab -l | /usr/bin/grep -iv command_to_execute | /usr/bin/crontab - 

it will execute your command one time and remove it from cron after that.

I have tried some hours now and the easiest way to stop browsers to jump to the anchor instead of scrolling to it is: Using another anchor (an id you do not use on the site). So instead of linking to "http://#YourActualID" you link to "http://#NoIDonYourSite". Poof, browsers won’t jump anymore.

Then just check if an anchor is set (with the script provided below, that is pulled out of the other thread!). And set your actual id you want to scroll to.

$(document).ready(function(){


  $(window).load(function(){
    // Remove the # from the hash, as different browsers may or may not include it
    var hash = location.hash.replace('#','');

    if(hash != ''){

       // Clear the hash in the URL
       // location.hash = '';   // delete front "//" if you want to change the address bar
        $('html, body').animate({ scrollTop: $('#YourIDtoScrollTo').offset().top}, 1000);

       }
   });
});

See https://lightningsoul.com/media/article/coding/30/YOUTUBE-SOCKREAD-SCRIPT-FOR-MIRC#content for a working example.

This is what I did and it works try and play around with it. It calculates total,avarage,minimum and maximum.

public static void main(String[] args) {
   int[] score= {56,90,89,99,59,67};
   double avg;
   int sum=0;
   int maxValue=0;
   int minValue=100;

   for(int i=0;i<6;i++){
       sum=sum+score[i];
   if(score[i]<minValue){
    minValue=score[i];
   }
   if(score[i]>maxValue){
    maxValue=score[i];
   }
   }
   avg=sum/6.0;
System.out.print("Max: "+maxValue+"," +" Min: "+minValue+","+" Avarage: "+avg+","+" Sum: "+sum);}

 }

You can use this tool as well. It is really useful.

BigSqlRunner

In HTML, elements containing nothing but normal whitespace characters are considered empty. A paragraph that contains just a normal space character will have zero height. A non-breaking space is a special kind of whitespace character that isn't considered to be insignificant, so it can be used as content for a non-empty paragraph.

Even if you consider CSS margins on paragraphs, since an "empty" paragraph has zero height, its vertical margins will collapse. This causes it to have no height and no margins, making it appear as if it were never there at all.

If you don't want to use a module you have to install like requests, and your use case is very basic, then you can use urllib2

urllib2.urlopen(url, body)

See the documentation for urllib2 here: https://docs.python.org/2/library/urllib2.html.

Before going to a command prompt, please follow these steps...

Open My Computer ? double click "C:" drive ? double click "Windows" ? double click "Microsoft.NET" ? double click "Framework" ? Inside this folder, there will be folder(s) like "v1.0.3705" and/or "v2.0.50727" and/or "v3.5" and/or "v4.0.30319".

Your latest .NET version would be in the highest v number folder, so if v4.0.30319 is available that would hold your latest .NET framework. However, the v4.0.30319 does not mean that you have the .NET framework version 4.0. The v4.0.30319 is your Visual C# compiler version, therefore, in order to find the .NET framework version do the following.

Go to a command prompt and follow this path:

C:\Windows\Microsoft.NET\Framework\v4.0.30319 (or whatever the highest v number folder)

C:\Windows\Microsoft.NET\Framework\v4.0.30319 > csc.exe

Output:

Microsoft (R) Visual C# Compiler version 4.0.30319.17929 for Microsoft (R) .NET Framework 4.5 Copyright (C) Microsoft Corporation. All rights reserved.

Example below:

Here's the result of running your code in Ipython. Note that result is a (2,0) array, 2 rows, 0 columns, 0 elements. The append produces a (2,) array. result[0] is (0,) array. Your error message has to do with trying to assign that 2 item array into a size 0 slot. Since result is dtype=float64, only scalars can be assigned to its elements.

In [65]: result=np.asarray([np.asarray([]),np.asarray([])])

In [66]: result
Out[66]: array([], shape=(2, 0), dtype=float64)

In [67]: result[0]
Out[67]: array([], dtype=float64)

In [68]: np.append(result[0],[1,2])
Out[68]: array([ 1.,  2.])

np.array is not a Python list. All elements of an array are the same type (as specified by the dtype). Notice also that result is not an array of arrays.

Result could also have been built as

ll = [[],[]]
result = np.array(ll)

while

ll[0] = [1,2]
# ll = [[1,2],[]]

the same is not true for result.

np.zeros((2,0)) also produces your result.

Actually there's another quirk to result.

result[0] = 1

does not change the values of result. It accepts the assignment, but since it has 0 columns, there is no place to put the 1. This assignment would work in result was created as np.zeros((2,1)). But that still can't accept a list.

But if result has 2 columns, then you can assign a 2 element list to one of its rows.

result = np.zeros((2,2))
result[0] # == [0,0]
result[0] = [1,2]

What exactly do you want result to look like after the append operation?

A bearer token is like a currency note e.g 100$ bill . One can use the currency note without being asked any/many questions.

Bearer Token A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

If you have JQuery loaded already, you can just do this:

$('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');

EDIT:

First load JQuery in the head tag:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>

Then call the Javascript to change the background image when something happens on the page, like when it finishes loading:

<script type="text/javascript">
    $(document).ready(function() {
        $('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');
    });
</script>

dear friend, Jon Skeet said you can find character Decimal codebut it is not character Hex code as it should mention in unicode, so you should represent character codes via HexCode not in Deciaml.

there is an open source tool at http://unicode.codeplex.com that provides complete information about a characer or a sentece.

so it is better to create a parser that give a char as a parameter and return ahexCode as string

public static String GetHexCode(char character)
    {
        return String.format("{0:X4}", GetDecimal(character));
    }//end

hope it help

simply provide the init block for HomeCell class

it's work in my case

To give you some idea:

public void paint(Graphics g) {
   drawCoordinates(g);
}

private void drawCoordinates(Graphics g) {

  // get width & height here (w,h)

  // define grid width (dh, dv)

  for (int x = 0; i < w; i += dh) {
    g.drawLine(x, 0, x, h);
  }
  for (int y = 0; j < h; j += dv) {
      g.drawLine(0, y, w, y);
  }
}

A solution with numpy for quick access to all indexes:

string_array = np.array(list(my_string))
char_indexes = np.where(string_array == 'C')

Use

/js/bootstrap.bundle.min.js

instead of

/js/bootstrap.min.js

If you are utilizing arrays too much then you should include cstring.h because it has too many functions including finding substrings.

I had the same problem when trying to use a token with Github.

The only syntax that has worked for me with Python 3 is:

import requests

myToken = '<token>'
myUrl = '<website>'
head = {'Authorization': 'token {}'.format(myToken)}
response = requests.get(myUrl, headers=head)

You're in that annoying boundary area where regexps almost won't do (as has been pointed out by Bart, escaping the quotes would make life hard) , and yet a full-blown parser seems like overkill.

If you are likely to need greater complexity any time soon I would go looking for a parser library. For example this one

For testing only two values, I'd personally do this:

if x ~= 0 and x ~= 1 then
    print( "X must be equal to 1 or 0" )
    return
end

If you need to test against more than two values, I'd stuff your choices in a table acting like a set, like so:

choices = {[0]=true, [1]=true, [3]=true, [5]=true, [7]=true, [11]=true}

if not choices[x] then
    print("x must be in the first six prime numbers")
    return
end

Check your X Window environment variables using the "env" command.

This should work:

DECLARE db_cursor CURSOR FOR SELECT name, age, color FROM table; 
DECLARE @myName VARCHAR(256);
DECLARE @myAge INT;
DECLARE @myFavoriteColor VARCHAR(40);
OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
WHILE @@FETCH_STATUS = 0  
BEGIN  

       --Do stuff with scalar values

       FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;

It might be that you have an expired development profile on your phone.

My development provisioning profile expired several days ago and I had to renew it. I installed the new profile on my phone and came up with the same error message when I tried to run my app. When I looked at the profile settings on my phone I noticed the expired profile and removed it. That cleared the error for me.

The size of a pointer is the size required by your system to hold a unique memory address (since a pointer just holds the address it points to)

Working with Intellij, because I don't know how to set keyboard shortcut to mvn spring-boot:run -Dspring.profiles.active=dev, I have to do this:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <jvmArguments>
            -Dspring.profiles.active=dev
        </jvmArguments>
    </configuration>
</plugin>

This works for me:

1. Right click on My Computer.
2. Select Manage.
3. Double click Services and Applications.
4. Then double click Services.
5. Right click on "World Wide Web Publishing Service".
6. Select Stop.

Node.js introduced async await in 7.6 so this makes Javascript more beautiful.

var results = [];
var config = JSON.parse(queries);
for (var key in config) {
  var query = config[key].query;
  results.push(await search(query));
}
res.writeHead( ... );
res.end(results);

For this to work search fucntion has to return a promise or it has to be async function

If it is not returning a Promise you can help it to return a Promise

function asyncSearch(query) {
  return new Promise((resolve, reject) => {
   search(query,(result)=>{
    resolve(result);
   })
  })
}

Then replace this line await search(query); by await asyncSearch(query);

If you want a generic solution using MutationObserver you can use this function

export function elementReady(selector) {
  return new Promise((resolve, reject) => {

Example how to use it

elementReady('#someWidget').then((someWidget)=>{someWidget.remove();});

Et voilà ! :)

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

You can also use convert to make the date searchable using LIKE. For example,

select convert(VARCHAR(40),create_date,121) , * from sys.objects where     convert(VARCHAR(40),create_date,121) LIKE '%17:34%'

Apart from the similarities i.e. Task.Run() being a shorthand for Task.Factory.StartNew(), there is a minute difference between their behaviour in case of sync and async delegates.

Suppose there are following two methods:

public async Task<int> GetIntAsync()
{
    return Task.FromResult(1);
}

public int GetInt()
{
    return 1;
}

Now consider the following code.

var sync1 = Task.Run(() => GetInt());
var sync2 = Task.Factory.StartNew(() => GetInt());

Here both sync1 and sync2 are of type Task<int>

However, difference comes in case of async methods.

var async1 = Task.Run(() => GetIntAsync());
var async2 = Task.Factory.StartNew(() => GetIntAsync());

In this scenario, async1 is of type Task<int>, however async2 is of type Task<Task<int>>

It seems that in general, this happens when Wordpress doesn't find the site information in the expected places (tables) in the database. It thinks no site has been created yet, so it starts going through the installation process.

This situation means that:

1. Wordpress WAS ABLE to connect to a database. If it didn't, it would say there was an error and refuse to install or do anything else

AND

2. it didn't find the things it was looking for in the expected places in the database it connected to.

Just to be clear, both 1) and 2) are happening when you see this symptom.

Possible causes:

• Wrong database. You're working on several projects and you copied and pasted wrong database name, database host, or table prefix to the wp-config file. So now, you're unwittingly destroying ANOTHER client's website while agonizing over why isn't THIS website working at all.

• Wrong database prefix. You can put several Wordpress sites in one database by using different prefixes for each. Make sure the tables in the database have the same prefixes as you entered in your wp-config. So, if wp-config says: $table_prefix = 'wp_'; Check that the tables in your database are called "wp_options", etc. and not "WP_options", "mysite_options" or something like that.

• The data in the database is corrupted. Maybe you messed up while importing the sql dump, you imported a truncated file, a file belonging to some other project, or whatever.

Human readable: (eg. can be log to text file..)

print_r( $arr_name , TRUE);

Other answers already cover how to filter by an address, but if you would like to exclude an address use

ip.addr < 192.168.0.11

MailAddress fromAddress = new MailAddress  (fromMail,fromName);
MailAddress toAddress = new MailAddress(toMail,toName);
MailMessage message = new MailMessage(fromAddress,toAddress);
message.Subject = subject;
message.Body = body;
SmtpClient smtp = new SmtpClient()
{
    Host = host, Port = port,
    enabHost = "smtp.gmail.com",
    Port = 25,
    EnableSsl = true,
    UseDefaultCredentials = true,
    Credentials = new  NetworkCredentials (fromMail, password)
};
smtp.send(message);

There is a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

When you use HttpClient with Observable, you have to use .subscribe(x=>...) in the rest of your code.

This is because Observable<HttpResponse<T>> is tied to HttpResponse.

This tightly couples the http layer with the rest of your code.

This library encapsulates the .subscribe(x => ...) part and exposes only the data and error through your Models.

With strongly-typed callbacks, you only have to deal with your Models in the rest of your code.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    getRaceInfo(success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.get(url, ResponseType.IObservable, success, ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the getRaceInfo API called as shown below.

  ngOnInit() {    
    this.service.getRaceInfo(response => this.result = response.result,
                                error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Also, you can still use the traditional route and return Observable<HttpResponse<T>> from Service API.

Runas doesn't magically run commands as an administrator, it runs them as whatever account you provide credentials for. If it's not an administrator account, runas doesn't care.

No, it's not possible in java.

You can do this way .. But try to avoid it.

one = two = three = "";
