Programs & Examples On #Httphandler

On windows server 2016 i have used:

dism /online /enable-feature /featurename:IIS-ASPNET45 /all

Also can be done via Powershell:

Install-WindowsFeature .NET-Framework-45-Features

I came across the same situation in my ASP.NET website. I deleted the published files, restarted VS, cleaned and rebuild the project again. After the next publish, the error was gone...

An ASP.NET HTTP handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page through the page handler. You can create your own HTTP handlers that render custom output to the browser.

You can also use

re.findall(r"\[([A-Za-z0-9_]+)\]", string)

if there are many occurrences that you would like to find.

Make sure the hamcrest jar is higher on the import order than your JUnit jar.

JUnit comes with its own org.hamcrest.Matcher class that is probably being used instead.

You can also download and use the junit-dep-4.10.jar instead which is JUnit without the hamcrest classes.

mockito also has the hamcrest classes in it as well, so you may need to move\reorder it as well

I tested below code and worked ok

Also I'm using library: org.apache.commons.lang.ArrayUtils

public void testConcatArrayString(){
    String[] a = null;
    String[] b = null;
    String[] c = null;
    a = new String[] {"1","2","3","4","5"};
    b = new String[] {"A","B","C","D","E"};

    c = (String[]) ArrayUtils.addAll(a, b);
    if(c!=null){
        for(int i=0; i<c.length; i++){
            System.out.println("c[" + (i+1) + "] = " + c[i]);
        }
    }
}

Yes - older POSIX standards defined usleep(), so this is available on Linux:

int usleep(useconds_t usec);

DESCRIPTION

The usleep() function suspends execution of the calling thread for (at least) usec microseconds. The sleep may be lengthened slightly by any system activity or by the time spent processing the call or by the granularity of system timers.

usleep() takes microseconds, so you will have to multiply the input by 1000 in order to sleep in milliseconds.

usleep() has since been deprecated and subsequently removed from POSIX; for new code, nanosleep() is preferred:

#include <time.h>

int nanosleep(const struct timespec *req, struct timespec *rem);

DESCRIPTION

nanosleep() suspends the execution of the calling thread until either at least the time specified in *req has elapsed, or the delivery of a signal that triggers the invocation of a handler in the calling thread or that terminates the process.

The structure timespec is used to specify intervals of time with nanosecond precision. It is defined as follows:

struct timespec {
    time_t tv_sec;        /* seconds */
    long   tv_nsec;       /* nanoseconds */
};

An example msleep() function implemented using nanosleep(), continuing the sleep if it is interrupted by a signal:

#include <time.h>
#include <errno.h>    

/* msleep(): Sleep for the requested number of milliseconds. */
int msleep(long msec)
{
    struct timespec ts;
    int res;

    if (msec < 0)
    {
        errno = EINVAL;
        return -1;
    }

    ts.tv_sec = msec / 1000;
    ts.tv_nsec = (msec % 1000) * 1000000;

    do {
        res = nanosleep(&ts, &ts);
    } while (res && errno == EINTR);

    return res;
}

hmmm, you can do it with a list comprehension. This would only make sense if you had a real range.. but it does do the job:

print([a for i in range(0,1) if b])

or using just those two variables:

print([a for a in range(a,a+1) if b])

There are many different ways to convert a datetime to a string. Here is one way:

SELECT convert(varchar(25), getdate(), 121)  – yyyy-mm-dd hh:mm:ss.mmm

See Demo

Here is a website that has a list of all of the conversions:

How to Format datetime & date in SQL Server

The following

function gettzdate(){
    var fd = moment().format('YYYY-MM-DDTHH:MM:ss');
    return fd ; 
}

works for forcing the current date onto a <input type="datetime-local">

Well here is a solution for you but I don't really understand why it works:

<html><body>
  <div style="width: 200px; border: 1px solid red;">Test</div>
  <div style="width: 200px; border: 1px solid blue; overflow: hidden; height: 1.5em;">My hovercraft is full of eels.  These pretzels are making me thirsty.</div>
  <div style="width: 200px; border: 1px solid yellow; overflow: hidden; height: 1.5em;">
  This_is_a_terrible_example_of_thinking_outside_the_box.
  </div>
  <table style="border: 2px solid black; border-collapse: collapse; width: 200px;"><tr>
   <td style="width:200px; border: 1px solid green; overflow: hidden; height: 1.5em;"><div style="width: 200px; border: 1px solid yellow; overflow: hidden;">
    This_is_a_terrible_example_of_thinking_outside_the_box.
   </div></td>
  </tr></table>
</body></html>

Namely, wrapping the cell contents in a div.

Use

where list.Contains(item.Property)

Or in your case:

var foo = from codeData in channel.AsQueryable<CodeData>()
          where codeIDs.Contains(codeData.CodeId)
          select codeData;

But you might as well do that in dot notation:

var foo = channel.AsQueryable<CodeData>()
                 .Where(codeData => codeIDs.Contains(codeData.CodeId));

@tcaswell already answered, but I was in the middle of typing my answer up, so I'll go ahead and post it...

There are a number of different ways you could do this. To begin with, matplotlib will automatically cycle through colors. By default, it cycles through blue, green, red, cyan, magenta, yellow, black:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
for i in range(1, 6):
    plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you want to control which colors matplotlib cycles through, use ax.set_color_cycle:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
fig, ax = plt.subplots()
ax.set_color_cycle(['red', 'black', 'yellow'])
for i in range(1, 6):
    plt.plot(x, i * x + i, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

If you'd like to explicitly specify the colors that will be used, just pass it to the color kwarg (html colors names are accepted, as are rgb tuples and hex strings):

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
for i, color in enumerate(['red', 'black', 'blue', 'brown', 'green'], start=1):
    plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

Finally, if you'd like to automatically select a specified number of colors from an existing colormap:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 1, 10)
number = 5
cmap = plt.get_cmap('gnuplot')
colors = [cmap(i) for i in np.linspace(0, 1, number)]

for i, color in enumerate(colors, start=1):
    plt.plot(x, i * x + i, color=color, label='$y = {i}x + {i}$'.format(i=i))
plt.legend(loc='best')
plt.show()

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);

I agree with @GregoryKlopper that the right way to solve the general problem of finding Waldo (or any object of interest) in an arbitrary image would be to train a supervised machine learning classifier. Using many positive and negative labeled examples, an algorithm such as Support Vector Machine, Boosted Decision Stump or Boltzmann Machine could likely be trained to achieve high accuracy on this problem. Mathematica even includes these algorithms in its Machine Learning Framework.

The two challenges with training a Waldo classifier would be:

1. Determining the right image feature transform. This is where @Heike's answer would be useful: a red filter and a stripped pattern detector (e.g., wavelet or DCT decomposition) would be a good way to turn raw pixels into a format that the classification algorithm could learn from. A block-based decomposition that assesses all subsections of the image would also be required ... but this is made easier by the fact that Waldo is a) always roughly the same size and b) always present exactly once in each image.
2. Obtaining enough training examples. SVMs work best with at least 100 examples of each class. Commercial applications of boosting (e.g., the face-focusing in digital cameras) are trained on millions of positive and negative examples.

A quick Google image search turns up some good data -- I'm going to have a go at collecting some training examples and coding this up right now!

However, even a machine learning approach (or the rule-based approach suggested by @iND) will struggle for an image like the Land of Waldos!

Well this should change your format to text.

Here's a very simply static encrypt/decrypt class biased on the Bouncy Castle no padding example by Jose Luis Montes de Oca. This one is using "DESede/ECB/PKCS7Padding" so I don't have to bother manually padding.

If you pass a variable data (dictionary type) as context to a template, then you code should be:

{% for key, value in data.items %}
    <p>{{ key }} : {{ value }}</p> 
{% endfor %}

I like Jesper's explanation in layman terms

By improvising examples from Jesper's answer,

class House {
// blue print for House Objects
}

class Car {
// blue print for Instances of Class Car 
}

House myHouse = new House();
Car myCar = new Car();

myHouse and myCar are objects

myHouse is an instance of House (relates Object-myHouse to its Class-House) myCar is an instance of Car

in short

"myHouse is an instance of Class House" which is same as saying "myHouse is an Object of type House"

If d = date(2011, 1, 1) is in UTC:

>>> from datetime import datetime, date
>>> import calendar
>>> timestamp1 = calendar.timegm(d.timetuple())
>>> datetime.utcfromtimestamp(timestamp1)
datetime.datetime(2011, 1, 1, 0, 0)

If d is in local timezone:

>>> import time
>>> timestamp2 = time.mktime(d.timetuple()) # DO NOT USE IT WITH UTC DATE
>>> datetime.fromtimestamp(timestamp2)
datetime.datetime(2011, 1, 1, 0, 0)

timestamp1 and timestamp2 may differ if midnight in the local timezone is not the same time instance as midnight in UTC.

mktime() may return a wrong result if d corresponds to an ambiguous local time (e.g., during DST transition) or if d is a past(future) date when the utc offset might have been different and the C mktime() has no access to the tz database on the given platform. You could use pytz module (e.g., via tzlocal.get_localzone()) to get access to the tz database on all platforms. Also, utcfromtimestamp() may fail and mktime() may return non-POSIX timestamp if "right" timezone is used.

To convert datetime.date object that represents date in UTC without calendar.timegm():

DAY = 24*60*60 # POSIX day in seconds (exact value)
timestamp = (utc_date.toordinal() - date(1970, 1, 1).toordinal()) * DAY
timestamp = (utc_date - date(1970, 1, 1)).days * DAY

How can I get a date converted to seconds since epoch according to UTC?

To convert datetime.datetime (not datetime.date) object that already represents time in UTC to the corresponding POSIX timestamp (a float).

Python 3.3+

datetime.timestamp():

from datetime import timezone

timestamp = dt.replace(tzinfo=timezone.utc).timestamp()

Note: It is necessary to supply timezone.utc explicitly otherwise .timestamp() assume that your naive datetime object is in local timezone.

Python 3 (< 3.3)

From the docs for datetime.utcfromtimestamp():

There is no method to obtain the timestamp from a datetime instance, but POSIX timestamp corresponding to a datetime instance dt can be easily calculated as follows. For a naive dt:

timestamp = (dt - datetime(1970, 1, 1)) / timedelta(seconds=1)

And for an aware dt:

timestamp = (dt - datetime(1970,1,1, tzinfo=timezone.utc)) / timedelta(seconds=1)

Interesting read: Epoch time vs. time of day on the difference between What time is it? and How many seconds have elapsed?

See also: datetime needs an "epoch" method

Python 2

To adapt the above code for Python 2:

timestamp = (dt - datetime(1970, 1, 1)).total_seconds()

where timedelta.total_seconds() is equivalent to (td.microseconds + (td.seconds + td.days * 24 * 3600) * 10**6) / 10**6 computed with true division enabled.

Example

from __future__ import division
from datetime import datetime, timedelta

def totimestamp(dt, epoch=datetime(1970,1,1)):
    td = dt - epoch
    # return td.total_seconds()
    return (td.microseconds + (td.seconds + td.days * 86400) * 10**6) / 10**6 

now = datetime.utcnow()
print now
print totimestamp(now)

Beware of floating-point issues.

Output

How to convert an aware datetime object to POSIX timestamp

assert dt.tzinfo is not None and dt.utcoffset() is not None
timestamp = dt.timestamp() # Python 3.3+

On Python 3:

from datetime import datetime, timedelta, timezone

epoch = datetime(1970, 1, 1, tzinfo=timezone.utc)
timestamp = (dt - epoch) / timedelta(seconds=1)
integer_timestamp = (dt - epoch) // timedelta(seconds=1)

On Python 2:

# utc time = local time              - utc offset
utc_naive  = dt.replace(tzinfo=None) - dt.utcoffset()
timestamp = (utc_naive - datetime(1970, 1, 1)).total_seconds()

To have greater control of the track color (no API controlled alpha changes), I extended SwitchCompat and style the elements programmatically:

    public class CustomizedSwitch extends SwitchCompat {

    public CustomizedSwitch(Context context) {
        super(context);
        initialize(context);
    }

    public CustomizedSwitch(Context context, AttributeSet attrs) {
        super(context, attrs);
        initialize(context);
    }

    public CustomizedSwitch(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initialize(context);
    }

    public void initialize(Context context) {
        // DisplayMeasurementConverter is just a utility to convert from dp to px and vice versa
        DisplayMeasurementConverter displayMeasurementConverter = new DisplayMeasurementConverter(context);
        // Sets the width of the switch
        this.setSwitchMinWidth(displayMeasurementConverter.dpToPx((int) getResources().getDimension(R.dimen.tp_toggle_width)));
        // Setting up my colors
        int mediumGreen = ContextCompat.getColor(context, R.color.medium_green);
        int mediumGrey = ContextCompat.getColor(context, R.color.medium_grey);
        int alphaMediumGreen = Color.argb(127, Color.red(mediumGreen), Color.green(mediumGreen), Color.blue(mediumGreen));
        int alphaMediumGrey = Color.argb(127, Color.red(mediumGrey), Color.green(mediumGrey), Color.blue(mediumGrey));
        // Sets the tints for the thumb in different states
        DrawableCompat.setTintList(this.getThumbDrawable(), new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_checked},
                        new int[]{}
                },
                new int[]{
                        mediumGreen,
                        ContextCompat.getColor(getContext(), R.color.light_grey)
                }));
        // Sets the tints for the track in different states
        DrawableCompat.setTintList(this.getTrackDrawable(), new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_checked},
                        new int[]{}
                },
                new int[]{
                        alphaMediumGreen,
                        alphaMediumGrey
                }));
    }
}

Whenever I want to use the CustomizedSwitch, I just add one to my xml file.

Edit: These are library functions. Following them is the manual way to do it.

I am absolutely stunned by the number of people unaware of __byteswap_ushort, __byteswap_ulong, and __byteswap_uint64. Sure they are Visual C++ specific, but they compile down to some delicious code on x86/IA-64 architectures. :)

Here's an explicit usage of the bswap instruction, pulled from this page. Note that the intrinsic form above will always be faster than this, I only added it to give an answer without a library routine.

uint32 cq_ntohl(uint32 a) {
    __asm{
        mov eax, a;
        bswap eax; 
    }
}

I'm fairly certain that the ls command is for Linux, not Windows (I'm assuming you're using Windows as you referred to cmd, which is the command line for the Windows OS).

You should use dir instead, which is the Windows equivalent of ls.

Edit (since this post seems to be getting so many views :) ):

You can't use ls on cmd as it's not shipped with Windows, but you can use it on other terminal programs (such as GitBash). Note, ls might work on some FTP servers if the servers are linux based and the FTP is being used from cmd.

dir on Windows is similar to ls. To find out the various options available, just do dir/?.

If you really want to use ls, you could install 3rd party tools to allow you to run unix commands on Windows. Such a program is Microsoft Windows Subsystem for Linux (link to docs).

I oddly ran into a similar issue with one of my .py files. I simply opened the file in Pycharm and pressed Option+Command+L which correctly formats the file contents in one go.

I suspect I was having trouble because I coded this particular .py file through jupyter labs as opposed to my usual choice of sublime text or Pycharm and therefore ran into some hidden indentation issues many answers here have alluded to

For installing standard toolboxes: Just insert your CD/DVD of MATLAB and start installing, when you see typical/Custom, choose custom and check the toolboxes you want to install and uncheck the others which are installed already.

In some cases the checkbox may be selected by default. If you want to restore default selection rather than set as unselected, compare the defaultChecked property.

$(':checkbox').each(function(i,item){ 
        this.checked = item.defaultChecked; 
}); 

I have also come across this need for my database project. I decided to share my findings here.

1) There is no way to a NOT NULL field without a default when data already exists (Can I add a not null column without DEFAULT value)

2) This topic has been addressed for a long time. Here is a 2008 question (Add a column with a default value to an existing table in SQL Server)

3) The DEFAULT constraint is used to provide a default value for a column. The default value will be added to all new records IF no other value is specified. (https://www.w3schools.com/sql/sql_default.asp)

4) The Visual Studio Database Project that I use for development is really good about generating change scripts for you. This is the change script created for my DB promotion:

GO
PRINT N'Altering [dbo].[PROD_WHSE_ACTUAL]...';

GO
ALTER TABLE [dbo].[PROD_WHSE_ACTUAL]
    ADD [DATE] DATE DEFAULT getdate() NOT NULL;

-

Here are the steps I took to update my database using Visual Studio for development.

1) Add default value (Visual Studio SSDT: DB Project: table designer)

2) Use the Schema Comparison tool to generate the change script.

code already provided above

3) View the data BEFORE applying the change.

4) View the data AFTER applying the change.

Use this

Let say Application Test.exe is running and function is foo() in form1 [basically it is class form1], then above code will generate below response.

string s1 = System.Reflection.MethodBase.GetCurrentMethod().DeclaringType.Name;

This will return .

s1 = "TEST.form1"

for function name:

string s1 = System.Reflection.MethodBase.GetCurrentMethod().Name;

will return

s1 = foo 

Note if you want to use this in exception use :

catch (Exception ex)
{

    MessageBox.Show(ex.StackTrace );

}

I think the Apache Commons Lang library's StringEscapeUtils.unescapeHtml3() and unescapeHtml4() methods are what you are looking for. See https://commons.apache.org/proper/commons-text/javadocs/api-release/org/apache/commons/text/StringEscapeUtils.html.

You can change the name of the column, therefore instead of "COUNT(*)" you would have something meaningful. You will have to update your "RowCount.sql" script for that.

For example:

SQL> select count(*) as RecordCountFromTableOne from TableOne;

Will be displayed as:

RecordCountFromTableOne
-----------------------
           0

If you want to have space in the title, you need to enclose it in double quotes

SQL> select count(*) as "Record Count From Table One" from TableOne;

Will be displayed as:

As aready proposed in this answer and this other answer Microsoft.VisualBasic.CompilerServices.Operators.LikeString could be a good option for simple tasks, when a RegExp is overkill. Syntax is different from RegExp and SQL LIKE operator, but it's really simple to learn (mainly because it's also very limited).

Assembly Microsoft.VisualBasic must be added as a reference to the project to use this method.

For more information see Operators.LikeString Method and for a description of the syntax see Like Operator (Visual Basic).

It can be used as an extension method to String class:

/// <summary>
/// Visual Basic like operator. Performs simple, case insensitive, string pattern matching.
/// </summary>
/// <param name="thisString"></param>
/// <param name="pattern"> ? = Any single character. * = Zero or more characters. # = Any single digit (0–9)</param>
/// <returns>true if the string matches the pattern</returns>
public static bool Like(this string thisString, string pattern)
    => Microsoft.VisualBasic.CompilerServices.Operators
        .LikeString(thisString, pattern, Microsoft.VisualBasic.CompareMethod.Text);

This function will recursively put only files into a list.

import os


def ls_files(dir):
    files = list()
    for item in os.listdir(dir):
        abspath = os.path.join(dir, item)
        try:
            if os.path.isdir(abspath):
                files = files + ls_files(abspath)
            else:
                files.append(abspath)
        except FileNotFoundError as err:
            print('invalid directory\n', 'Error: ', err)
    return files

int is a primitive type, you can read what does mean a primitive type in java here, and a Map is an interface that has to objects as input:

public interface Map<K extends Object, V extends Object>

object means a class, and it means also that you can create an other class that exends from it, but you can not create a class that exends from int. So you can not use int variable as an object. I have tow solutions for your problem:

Map<String, Integer> map = new HashMap<>();

or

Map<String, int[]> map = new HashMap<>();
int x = 1;

//put x in map
int[] x_ = new int[]{x};
map.put("x", x_);

//get the value of x
int y = map.get("x")[0];

I tried all of the above suggestions, which did not work for me, but I found how to fix the error in my case.

The following steps made the project compile succesfully:

In project explorer, right-click on project, select “properties” In the tree on the right, go to Java build path. Select the tab “libraries”. Click “Add library”. Select JRE system library. Click next. Select radio button Alternate JRE. Click “installed JRE’s”. Select the JRE with the right version. Click Appy and close. In the next screen, click finish. In the properties window, click Apply and close. In the project explorer, right-click your pom.xml and select run as > maven build In the goal textbox, write “install”. Click Run.

This made the project build succesfully in my case.

This error can be caused when you are requesting a value from something and you put parenthesis at the end, as if it is a function call, yet the value is correctly retrieved without ending parenthesis. For example, if what you are accessing is a Property 'get' in Typescript.

private IMadeAMistakeHere(): void {
    let mynumber = this.SuperCoolNumber();
}

private IDidItCorrectly(): void {
    let mynumber = this.SuperCoolNumber;
}

private get SuperCoolNumber(): number {
    let response = 42;
    return response;
};

I think there is no standard syntax for command line usage, but most use this convention:

Microsoft Command-Line Syntax, IBM has similar Command-Line Syntax

• Text without brackets or braces

  Items you must type as shown
  
  

• <Text inside angle brackets>

  Placeholder for which you must supply a value
  
  

• [Text inside square brackets]

  Optional items
  
  

• {Text inside braces}

  Set of required items; choose one
  
  

• Vertical bar {a|b}

  Separator for mutually exclusive items; choose one
  
  

• Ellipsis <file> …

  Items that can be repeated
  
  

For performance reasons, please do not use recursion. It would be disastrous.

def fact(n, total=1):
    while True:
        if n == 1:
            return total
        n, total = n - 1, total * n

Check running results

cProfile.run('fact(126000)')

4 function calls in 5.164 seconds

Using the stack is convenient(like recursive call), but it comes at a cost: storing detailed information can take up a lot of memory.

If the stack is high, it means that the computer stores a lot of information about function calls.

The method only takes up constant memory(like iteration).

Or Using for loop

def fact(n):
    result = 1
    for i in range(2, n + 1):
        result *= i
    return result

Check running results

cProfile.run('fact(126000)')

4 function calls in 4.708 seconds

Or Using builtin function math

def fact(n):
    return math.factorial(n)

Check running results

cProfile.run('fact(126000)')

5 function calls in 0.272 seconds

              ),
            ),
          ),
          ),

Working from what you've given I'll assume you want to check that someone has NOT entered any letters other than the ones you've listed. For that to work you want to search for any characters other than those listed:

[^A-Za-z0-9_.]

And use that in a match in your code, something like:

if ( /[^A-Za-z0-9_.]/.match( your_input_string ) ) {
   alert( "you have entered invalid data" );
}

Hows that?

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

Take a look at the inspect module - this will do the inspection of the various code object properties for you.

>>> inspect.getfullargspec(a_method)
(['arg1', 'arg2'], None, None, None)

The other results are the name of the *args and **kwargs variables, and the defaults provided. ie.

>>> def foo(a, b, c=4, *arglist, **keywords): pass
>>> inspect.getfullargspec(foo)
(['a', 'b', 'c'], 'arglist', 'keywords', (4,))

Note that some callables may not be introspectable in certain implementations of Python. For Example, in CPython, some built-in functions defined in C provide no metadata about their arguments. As a result, you will get a ValueError if you use inspect.getfullargspec() on a built-in function.

Since Python 3.3, you can use inspect.signature() to see the call signature of a callable object:

>>> inspect.signature(foo)
<Signature (a, b, c=4, *arglist, **keywords)>

If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw always interrupt the execution flow of the current method. a try/catch block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.

Find this tutorial about exception and how they work - http://docs.oracle.com/javase/tutorial/essential/exceptions/

These days, if you use two different video formats (WebM and HEVC), you can have a transparent video that works in all of the major browsers except Internet Explorer with a simple <video> tag:

<video>
  <source src="video.webm" type="video/webm">
  <source src="video.mov" type="video/quicktime">
</video>

Here's a demo you can test with

You need to configure Apache (the webserver) to process PHP scripts as PHP. Check Apache's configuration. You need to load the module (the path may differ on your system):

LoadModule php5_module "c:/php/php5apache.dll"

And you also need to tell Apache what to process with PHP:

AddType application/x-httpd-php .php

See the documentation for more details.

Swift 3

For a simple solution without third party code:

Just use a normal UIAlertController but with style = actionSheet (look at code down below)

let alertDisapperTimeInSeconds = 2.0
let alert = UIAlertController(title: nil, message: "Toast!", preferredStyle: .actionSheet)
self.present(alert, animated: true)
DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + alertDisapperTimeInSeconds) {
  alert.dismiss(animated: true)
}

The advantage of this solution:

1. Android like Toast message
2. Still iOS Look&Feel

I resolved it by following what Eddi mentioned above,

 resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "26.1.0"
            }
        }

@dfa answer is great, so I took it a step farther to make it possible to test blocks of ouput.

First I created TestHelper with a method captureOutput that accepts the annoymous class CaptureTest. The captureOutput method does the work of setting and tearing down the output streams. When the implementation of CaptureOutput's test method is called, it has access to the output generate for the test block.

Source for TestHelper:

public class TestHelper {

    public static void captureOutput( CaptureTest test ) throws Exception {
        ByteArrayOutputStream outContent = new ByteArrayOutputStream();
        ByteArrayOutputStream errContent = new ByteArrayOutputStream();

        System.setOut(new PrintStream(outContent));
        System.setErr(new PrintStream(errContent));

        test.test( outContent, errContent );

        System.setOut(new PrintStream(new FileOutputStream(FileDescriptor.out)));
        System.setErr(new PrintStream(new FileOutputStream(FileDescriptor.out)));

    }
}

abstract class CaptureTest {
    public abstract void test( ByteArrayOutputStream outContent, ByteArrayOutputStream errContent ) throws Exception;
}

Note that TestHelper and CaptureTest are defined in the same file.

Then in your test, you can import the static captureOutput. Here is an example using JUnit:

// imports for junit
import static package.to.TestHelper.*;

public class SimpleTest {

    @Test
    public void testOutput() throws Exception {

        captureOutput( new CaptureTest() {
            @Override
            public void test(ByteArrayOutputStream outContent, ByteArrayOutputStream errContent) throws Exception {

                // code that writes to System.out

                assertEquals( "the expected output\n", outContent.toString() );
            }
        });
}

You aren't building your formula right.

Worksheets("EmployeeCosts").Range("B" & var1a).Formula =  "=SUM(H5:H" & var1a & ")"

This does the same as the following lines do:

Dim myFormula As String
myFormula = "=SUM(H5:H"
myFormula = myFormula & var1a
myformula = myformula & ")"

which is what you are trying to do.

Also, you want to have the = at the beginning of the formala.

I was face same problem when I am going to delete my record than some issue was occur , for this issue solution is that when you are going to delete your record than you missing some thing before deleting header/master record you must write to code for delete its detail before header/Master I hope you issue will be resolve.

As always with reference types, there are two notions of "copy". I'm sure you know them, but for completeness.

1. A bitwise copy. In this, we just copy the memory bit for bit - this is what NSCopyObject does. Nearly always, it's not what you want. Objects have internal state, other objects, etc, and often make assumptions that they're the only ones holding references to that data. Bitwise copies break this assumption.
2. A deep, logical copy. In this, we make a copy of the object, but without actually doing it bit by bit - we want an object that behaves the same for all intents and purposes, but isn't (necessarily) a memory-identical clone of the original - the Objective C manual calls such an object "functionally independent" from it's original. Because the mechanisms for making these "intelligent" copies varies from class to class, we ask the objects themselves to perform them. This is the NSCopying protocol.

You want the latter. If this is one of your own objects, you need simply adopt the protocol NSCopying and implement -(id)copyWithZone:(NSZone *)zone. You're free to do whatever you want; though the idea is you make a real copy of yourself and return it. You call copyWithZone on all your fields, to make a deep copy. A simple example is

@interface YourClass : NSObject <NSCopying> 
{
   SomeOtherObject *obj;
}

// In the implementation
-(id)copyWithZone:(NSZone *)zone
{
  // We'll ignore the zone for now
  YourClass *another = [[YourClass alloc] init];
  another.obj = [obj copyWithZone: zone];

  return another;
}

Now with react-router v5 you can use the useHistory hook like this:

import { useHistory } from "react-router-dom";

function HomeButton() {
  let history = useHistory();

  function handleClick() {
    history.push("/home");
  }

  return (
    <button type="button" onClick={handleClick}>
      Go home
    </button>
  );
}

Argument is often used in the sense of actual argument vs. formal parameter.

The formal parameter is what is given in the function declaration/definition/prototype, while the actual argument is what is passed when calling the function — an instance of a formal parameter, if you will.

That being said, they are often used interchangeably, their exact use depending on different programming languages and their communities. For example, I have also heard actual parameter etc.

So here, x and y would be formal parameters:

int foo(int x, int y) {
    ...
}

Whereas here, in the function call, 5 and z are the actual arguments:

foo(5, z);

Instead of ng-options="product as product.label for product in products"> in the select element, you can even use this:

<option ng-repeat="product in products" value="{{product.label}}">{{product.label}}

which works just fine as well.

At the VS code

press Ctrl+Shift+P

then type Format Document With...

At the end of the list click on Configure Default Formatter...

Now you can choose your favorite beautifier from the list.

Update 2021

if "Format Document With..." didn't exist any more, go to file => preferences => settings then navigate to Extensions => Vetur scroll a little bit then you will see format > defaultFormatter:css, now you can pick any document formatter that you installed bofer for different file type extensions.

Sometimes this occurs when you have the folder of the package you are trying to restore inside the "packages" folder (i.e. "Packages/EntityFramework.6.0.0/") but the "DLLs" are not inside it (most of the version control systems automatically ignore ".dll" files). This occurs because before NuGet tries to restore each package it checks if the folders already exist, so if it exists, NuGet assumes that the "dll" is inside it. So if this is the problem for you just delete the folder that NuGet will restore it correctly.

Just another hint for those who need to massively convert bytes to binary strings: Use a lookup table instead of using those String operation all the time. This is a lot faster than calling the convert function over and over again

public class ByteConverterUtil {

  private static final String[] LOOKUP_TABLE = IntStream.range(0, Byte.MAX_VALUE - Byte.MIN_VALUE + 1)
                                                        .mapToObj(intValue -> Integer.toBinaryString(intValue + 0x100).substring(1))
                                                        .toArray(String[]::new);

  public static String convertByte(final byte byteValue) {
    return LOOKUP_TABLE[Byte.toUnsignedInt(byteValue)];
  }

  public static void main(String[] args){
    System.out.println(convertByte((byte)0)); //00000000
    System.out.println(convertByte((byte)2)); //00000010
    System.out.println(convertByte((byte)129)); //10000001
    System.out.println(convertByte((byte)255)); //11111111
  }


}

Use command:

git tag v1.0 ec32d32

Where v1.0 is the tag name and ec32d32 is the commit you want to tag

Once done you can push the tags by:

git push origin --tags

int** create2DArray(unsigned height, unsigned width)
{
     int** array2D = 0;
     array2D = new int*[height];

     for (int h = 0; h < height; h++)
     {
          array2D[h] = new int[width];

          for (int w = 0; w < width; w++)
          {
               // fill in some initial values
               // (filling in zeros would be more logic, but this is just for the example)
               array2D[h][w] = w + width * h;
          }
     }

     return array2D;
}

int main ()
{

    printf("Creating a 2D array2D\n");
    printf("\n");

    int height = 15;
    int width = 10;
    int** my2DArray = create2DArray(height, width);
    printf("Array sized [%i,%i] created.\n\n", height, width);

    // print contents of the array2D
    printf("Array contents: \n");

    for (int h = 0; h < height; h++)
    {
         for (int w = 0; w < width; w++)
         {
              printf("%i,", my2DArray[h][w]);
         }
         printf("\n");
    }

    return 0;
}

You could also define a variable in a jinja2 template like this:

{% if step is not defined %}
{% set step = 1 %}
{% endif %}

And then You can use it like this:

{% if step == 1 %}
<div class="col-xs-3 bs-wizard-step active">
{% elif step > 1 %}
<div class="col-xs-3 bs-wizard-step complete">
{% else %}
<div class="col-xs-3 bs-wizard-step disabled">
{% endif %}

Otherwise (if You wouldn't use {% set step = 1 %}) the upper code would throw:

UndefinedError: 'step' is undefined

$var:25%;
$foo:5px;
.selector {
    height:unquote("calc( #{$var} - #{$foo} )");
}

Try this:

select * from T_PARTNER 
where C_DISTRIBUTOR_TYPE_ID = 6 and
translate(C_PARTNER_ID, '.1234567890', '.') is null;

I'm adding another option. The answers above were very useful for me, but I wanted to use jQuery instead of ic-ajax (it seems to have a dependency with Ember when I tried to install through bower). Keep in mind that this solution only works on modern browsers.

In order to implement this on jQuery I used jQuery BinaryTransport. This is a nice plugin to read AJAX responses in binary format.

Then you can do this to download the file and send the headers:

$.ajax({
    url: url,
    type: 'GET',
    dataType: 'binary',
    headers: headers,
    processData: false,
    success: function(blob) {
        var windowUrl = window.URL || window.webkitURL;
        var url = windowUrl.createObjectURL(blob);
        anchor.prop('href', url);
        anchor.prop('download', fileName);
        anchor.get(0).click();
        windowUrl.revokeObjectURL(url);
    }
});

The vars in the above script mean:

• url: the URL of the file
• headers: a Javascript object with the headers to send
• fileName: the filename the user will see when downloading the file
• anchor: it is a DOM element that is needed to simulate the download that must be wrapped with jQuery in this case. For example $('a.download-link').

I resolve similar problem with:

document.getElementById("xyz").style.padding = "10px 0 0 0";

Hope that helps.

AWS RDS users if you are getting this it is because you are not a superuser and according to aws documentation you cannot be one. I have found I have to ignore these errors.

I don't think there are any machine code decompilers that produce Pascal code. Most "Delphi decompilers" parse form and RTTI data, but do not actually decompile the machine code. I can only recommend using something like DeDe (or similar software) to extract symbol information in combination with a C decompiler, then translate the decompiled C code to Delphi (there are many source code converters out there).

1. Make sure you have your name and % the right way round
2. Makes sure you have added your port 3306 to any firewall you may be running (although this will give a different error message)

hope this helps someone...

You can also try jQuery based method:

$(document).ready(function() {
    $('form:first *:input[type!=hidden]:first').focus();
});

Inspecting and mocking request body

When you first read the body, you have to store it so once you're done with it, you can set a new io.ReadCloser as the request body constructed from the original data. So when you advance in the chain, the next handler can read the same body.

One option is to read the whole body using ioutil.ReadAll(), which gives you the body as a byte slice.

You may use bytes.NewBuffer() to obtain an io.Reader from a byte slice.

The last missing piece is to make the io.Reader an io.ReadCloser, because bytes.Buffer does not have a Close() method. For this you may use ioutil.NopCloser() which wraps an io.Reader, and returns an io.ReadCloser, whose added Close() method will be a no-op (does nothing).

Note that you may even modify the contents of the byte slice you use to create the "new" body. You have full control over it.

^{Care must be taken though, as there might be other HTTP fields like content-length and checksums which may become invalid if you modify only the data. If subsequent handlers check those, you would also need to modify those too!}

Inspecting / modifying response body

If you also want to read the response body, then you have to wrap the http.ResponseWriter you get, and pass the wrapper on the chain. This wrapper may cache the data sent out, which you can inspect either after, on on-the-fly (as the subsequent handlers write to it).

Here's a simple ResponseWriter wrapper, which just caches the data, so it'll be available after the subsequent handler returns:

type MyResponseWriter struct {
    http.ResponseWriter
    buf *bytes.Buffer
}

func (mrw *MyResponseWriter) Write(p []byte) (int, error) {
    return mrw.buf.Write(p)
}

Note that MyResponseWriter.Write() just writes the data to a buffer. You may also choose to inspect it on-the-fly (in the Write() method) and write the data immediately to the wrapped / embedded ResponseWriter. You may even modify the data. You have full control.

^{Care must be taken again though, as the subsequent handlers may also send HTTP response headers related to the response data –such as length or checksums– which may also become invalid if you alter the response data.}

Full example

Putting the pieces together, here's a full working example:

func loginmw(handler http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        body, err := ioutil.ReadAll(r.Body)
        if err != nil {
            log.Printf("Error reading body: %v", err)
            http.Error(w, "can't read body", http.StatusBadRequest)
            return
        }

        // Work / inspect body. You may even modify it!

        // And now set a new body, which will simulate the same data we read:
        r.Body = ioutil.NopCloser(bytes.NewBuffer(body))

        // Create a response wrapper:
        mrw := &MyResponseWriter{
            ResponseWriter: w,
            buf:            &bytes.Buffer{},
        }

        // Call next handler, passing the response wrapper:
        handler.ServeHTTP(mrw, r)

        // Now inspect response, and finally send it out:
        // (You can also modify it before sending it out!)
        if _, err := io.Copy(w, mrw.buf); err != nil {
            log.Printf("Failed to send out response: %v", err)
        }
    })
}

As an alternative to @Mark Byers' approach, you can use while True:

guess = 50     # this should be outside the loop, I think
while True:    # infinite loop
    n = raw_input("\n\nTrue, False or Correct?: ")
    if n == "Correct":
        break  # stops the loop
    elif n == "True":
        # etc.

They're completely different. Objective C has more in common with Smalltalk than with C++ (well, except for the syntax, really).

Below query will provide exactly the same result as given in the desired response:

db.books.aggregate([
    {
        $group: {
            _id: { addresses: "$addr", books: "$book" },
            num: { $sum :1 }
        }
    },
    {
        $group: {
            _id: "$_id.addresses",
            bookCounts: { $push: { bookName: "$_id.books",count: "$num" } }
        }
    },
    {
        $project: {
            _id: 1,
            bookCounts:1,

To get Ant running on your Mac in 5 minutes, follow these steps.

Open up your terminal.

Perform these commands in order:

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew install ant

If you don't have Java installed yet, you will get the following error: "Error: An unsatisfied requirement failed this build." Run this command next: brew cask install java to fix this.

The installation will resume.

Check your version of by running this command:

ant -version

And you're ready to go!

Faced with this same problem, I discovered if you have committed and/or pushed to remote since your successful cherry-pick, and you want to remove it, you can find the cherry-pick's SHA by running:

git log --graph --decorate --oneline

Then, (after using :wq to exit the log) you can remove the cherry-pick using

git rebase -p --onto YOUR_SHA_HERE^ YOUR_SHA_HERE

where YOUR_SHA_HERE equals the cherry-picked commit's 40- or abbreviated 7-character SHA.

At first, you won't be able to push your changes because your remote repo and your local repo will have different commit histories. You can force your local commits to replace what's on your remote by using

git push --force origin YOUR_REPO_NAME

(I adapted this solution from Seth Robertson: See "Removing an entire commit.")

This will pop a dialog asking the user if he really wants to close or stay, with a message.

var message = "You have not filled out the form.";
window.onbeforeunload = function(event) {
    var e = e || window.event;
    if (e) {
        e.returnValue = message;
    }
    return message;
};

You can then unset it before the form gets submitted or something else with

window.onbeforeunload = null;

Keep in mind that this is extremely annoying. If you are trying to force your users to fill out a form that they don't want to fill out, then you will fail: they will find a way to close the window and never come back to your mean website.

The core thing is to define prefixes for namespaces and use them to fortify each and every tag - you are mixing 3 namespaces and that just doesn't fly by trying to hack defaults. It's also good to use exactly the prefixes used in the standard doc - just in case that the other side get a little sloppy.

Last but not least, it's much better to use default types for fields whenever you can - so for password you have to list the type, for the Nonce it's already Base64.

Make sure that you check that the generated token is correct before you send it via XML and don't forget that the content of wsse:Password is Base64( SHA-1 (nonce + created + password) ) and date-time in wsu:Created can easily mess you up. So once you fix prefixes and namespaces and verify that yout SHA-1 work fine without XML (just imagine you are validating the request and do the server side of SHA-1 calculation) you can also do a truial wihtout Created and even without Nonce. Oh and Nonce can have different encodings so if you really want to force another encoding you'll have to look further into wsu namespace.

If you have access to manipulate the code of the site you are loading, the following should provide a comprehensive method to updating the height of the iframe container anytime the height of the framed content changes.

Add the following code to the pages you are loading (perhaps in a header). This code sends a message containing the height of the HTML container any time the DOM is updated (if you're lazy loading) or the window is resized (when the user modifies the browser).

window.addEventListener("load", function(){
    if(window.self === window.top) return; // if w.self === w.top, we are not in an iframe 
    send_height_to_parent_function = function(){
        var height = document.getElementsByTagName("html")[0].clientHeight;
        //console.log("Sending height as " + height + "px");
        parent.postMessage({"height" : height }, "*");
    }
    // send message to parent about height updates
    send_height_to_parent_function(); //whenever the page is loaded
    window.addEventListener("resize", send_height_to_parent_function); // whenever the page is resized
    var observer = new MutationObserver(send_height_to_parent_function);           // whenever DOM changes PT1
    var config = { attributes: true, childList: true, characterData: true, subtree:true}; // PT2
    observer.observe(window.document, config);                                            // PT3 
});

Add the following code to the page that the iframe is stored on. This will update the height of the iframe, given that the message came from the page that that iframe loads.

<script>
window.addEventListener("message", function(e){
    var this_frame = document.getElementById("healthy_behavior_iframe");
    if (this_frame.contentWindow === e.source) {
        this_frame.height = e.data.height + "px";
        this_frame.style.height = e.data.height + "px";
    }
})
</script>

Matplotlib chooses Xwindows backend by default. You need to set matplotlib to not use the Xwindows backend.

Add this code to the start of your script (before importing pyplot) and try again:

import matplotlib
matplotlib.use('Agg')

Or add to .config/matplotlib/matplotlibrc line backend: Agg to use non-interactive backend.

echo "backend: Agg" > ~/.config/matplotlib/matplotlibrc

Or when connect to server use ssh -X remoteMachine command to use Xwindows.

Also you may try to export display: export DISPLAY=mymachine.com:0.0.

In android-N, this feature is included in it. check Number-blocking update for android N

Android N now supports number-blocking in the platform and provides a framework API to let service providers maintain a blocked-number list. The default SMS app, the default phone app, and provider apps can read from and write to the blocked-number list. The list is not accessible to other app.

advantage of are:

1. Numbers blocked on calls are also blocked on texts
2. Blocked numbers can persist across resets and devices through the Backup & Restore feature
3. Multiple apps can use the same blocked numbers list

For more information, see android.provider.BlockedNumberContract

Update an existing project.

To compile your app against the Android N platform, you need to use the Java 8 Developer Kit (JDK 8), and in order to use some tools with Android Studio 2.1, you need to install the Java 8 Runtime Environment (JRE 8).

Open the build.gradle file for your module and update the values as follows:

android {
  compileSdkVersion 'android-N'
  buildToolsVersion 24.0.0 rc1
  ...

  defaultConfig {
     minSdkVersion 'N'
     targetSdkVersion 'N'
     ...
  }
  ...
}

This is a late contribution, but there is a valid case for casting json_decode with (array).
Consider the following:

$jsondata = '';
$arr = json_decode($jsondata, true);
foreach ($arr as $k=>$v){
    echo $v; // etc.
}

If $jsondata is ever returned as an empty string (as in my experience it often is), json_decode will return NULL, resulting in the error Warning: Invalid argument supplied for foreach() on line 3. You could add a line of if/then code or a ternary operator, but IMO it's cleaner to simply change line 2 to ...

$arr = (array) json_decode($jsondata,true);

... unless you are json_decodeing millions of large arrays at once, in which case as @TCB13 points out, performance could be negatively effected.

If it's running all of the above from the command line that you're looking for, then I'd recommend HTTPie. It is a fantastic cURL alternative and is super easy and convenient to use (and customize).

Here's is its (succinct and precise) description from GitHub;

HTTPie (pronounced aych-tee-tee-pie) is a command line HTTP client. Its goal is to make CLI interaction with web services as human-friendly as possible.

It provides a simple http command that allows for sending arbitrary HTTP requests using a simple and natural syntax, and displays colorized output. HTTPie can be used for testing, debugging, and generally interacting with HTTP servers.

For the pull to refresh i am using

DGElasticPullToRefresh

https://github.com/gontovnik/DGElasticPullToRefresh

Installation

pod 'DGElasticPullToRefresh'

import DGElasticPullToRefresh

and put this function into your swift file and call this funtion from your

override func viewWillAppear(_ animated: Bool)

     func Refresher() {
      let loadingView = DGElasticPullToRefreshLoadingViewCircle()
      loadingView.tintColor = UIColor(red: 255.0/255.0, green: 255.0/255.0, blue: 255.0/255.0, alpha: 1.0)
      self.table.dg_addPullToRefreshWithActionHandler({ [weak self] () -> Void in

          //Completion block you can perfrom your code here.

           print("Stack Overflow")

           self?.table.dg_stopLoading()
           }, loadingView: loadingView)
      self.table.dg_setPullToRefreshFillColor(UIColor(red: 255.0/255.0, green: 57.0/255.0, blue: 66.0/255.0, alpha: 1))
      self.table.dg_setPullToRefreshBackgroundColor(self.table.backgroundColor!)
 }

And dont forget to remove reference while view will get dissapear

to remove pull to refresh put this code in to your

override func viewDidDisappear(_ animated: Bool)

override func viewDidDisappear(_ animated: Bool) {
      table.dg_removePullToRefresh()

 }

And it will looks like

Happy coding :)

Frequently, we may need to calculate Median not just for the whole table, but for aggregates with respect to some ID. In other words, calculate median for each ID in our table, where each ID has many records. (based on the solution edited by @gdoron: good performance and works in many SQL)

SELECT our_id, AVG(1.0 * our_val) as Median
FROM
( SELECT our_id, our_val, 
  COUNT(*) OVER (PARTITION BY our_id) AS cnt,
  ROW_NUMBER() OVER (PARTITION BY our_id ORDER BY our_val) AS rnk
  FROM our_table
) AS x
WHERE rnk IN ((cnt + 1)/2, (cnt + 2)/2) GROUP BY our_id;

Hope it helps.

From a practical point of view, MVC (Model-View-Controller) is a pattern. However, MVC when used as ASP.net MVC, when combined with Entity Framework (EF) and the "power tools" is a very powerful, partially automated approach for bringing databases, tables, and columns to a web-page, for either full CRUD operations or R (Retrieve or Read) operations only. At least as I used MVVM, the View Models interacted with models that depended upon business objects, which were in turn "hand-made" and after a lot of effort, one was lucky to get models as good as what EF gives one "out-of-the-box". From a practical programming point of view, MVC seems a good choice because it gives one lots of utility out-of-box, but there is still a potential for bells-and-whistles to be added.

If you are using SQL Server 2012 or above versions,

Use Format() function.

There are already multiple answers and formatting types for SQL server. But most of the methods are somewhat ambiguous and it would be difficult for you to remember the numbers for format type or functions with respect to Specific Date Format. That's why in next versions of SQL server there is better option.

FORMAT ( value, format [, culture ] )

Culture option is very useful, as you can specify date as per your viewers.

You have to remember d (for small patterns) and D (for long patterns).

1."d" - Short date pattern.

2009-06-15T13:45:30 -> 6/15/2009 (en-US)
2009-06-15T13:45:30 -> 15/06/2009 (fr-FR)
2009-06-15T13:45:30 -> 2009/06/15 (ja-JP)

2."D" - Long date pattern.

2009-06-15T13:45:30 -> Monday, June 15, 2009 (en-US)
2009-06-15T13:45:30 -> 15 ???? 2009 ?. (ru-RU)
2009-06-15T13:45:30 -> Montag, 15. Juni 2009 (de-DE)

If you want more formats, you can go to:

1. Standard Date and Time Format Strings
2. Custom Date and Time Format Strings

Use utcOffset function.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).utcOffset(10 * 60); //set timezone offset in minutes
console.log(localDate.format()); //2015-01-30T20:00:00+10:00

I got this error after I accidentally published one website into the directory of another website. The two websites had different versions of .net. What fixed it for me was changing the application pool. To do that, in the IIS manager:

click the website => Advanced Settings... (on the right) => click to the right of Application Pool => a button with "..." should appear => select ".NET v4.5 Classic"

If that application pool doesn't work, try some of the others.

CREDIT: Programmatic access to properties in Spring without re-reading the properties file

I've found a nice implementation of accessing the properties programmatically in spring without reloading the same properties that spring has already loaded. [Also, It is not required to hardcode the property file location in the source]

With these changes, the code looks cleaner & more maintainable.

The concept is pretty simple. Just extend the spring default property placeholder (PropertyPlaceholderConfigurer) and capture the properties it loads in the local variable

public class SpringPropertiesUtil extends PropertyPlaceholderConfigurer {

    private static Map<String, String> propertiesMap;
    // Default as in PropertyPlaceholderConfigurer
    private int springSystemPropertiesMode = SYSTEM_PROPERTIES_MODE_FALLBACK;

    @Override
    public void setSystemPropertiesMode(int systemPropertiesMode) {
        super.setSystemPropertiesMode(systemPropertiesMode);
        springSystemPropertiesMode = systemPropertiesMode;
    }

    @Override
    protected void processProperties(ConfigurableListableBeanFactory beanFactory, Properties props) throws BeansException {
        super.processProperties(beanFactory, props);

        propertiesMap = new HashMap<String, String>();
        for (Object key : props.keySet()) {
            String keyStr = key.toString();
            String valueStr = resolvePlaceholder(keyStr, props, springSystemPropertiesMode);
            propertiesMap.put(keyStr, valueStr);
        }
    }

    public static String getProperty(String name) {
        return propertiesMap.get(name).toString();
    }

}

Usage Example

SpringPropertiesUtil.getProperty("myProperty")

Spring configuration changes

<bean id="placeholderConfigMM" class="SpringPropertiesUtil">
    <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
    <property name="locations">
    <list>
        <value>classpath:myproperties.properties</value>
    </list>
    </property>
</bean>

Hope this helps to solve the problems you have

You can use find and -exec directly into sed rather than first locating oldstr with grep. It's maybe a bit less efficient, but that might not be important. This way, the sed replacement is executed over all files listed by find, but if oldstr isn't there it obviously won't operate on it.

find /path -type f -exec sed -i 's/oldstr/newstr/g' {} \;

Based on some of the previous answers, I'm going to break my answer down into three areas.

First, physical limitations of using Action<T1, T2, T2... > vs using a derived class of EventArgs. There are three: First, if you change the number or types of parameters, every method that subscribes to will have to be changed to conform to the new pattern. If this is a public facing event that 3rd party assemblies will be using, and there is any possiblity that the event args would change, this would be a reason to use a custom class derived from event args for consistencies sake (remember, you COULD still use an Action<MyCustomClass>) Second, using Action<T1, T2, T2... > will prevent you from passing feedback BACK to the calling method unless you have a some kind of object (with a Handled property for instance) that is passed along with the Action. Third, you don't get named parameters, so if you're passing 3 bool's an int, two string's, and a DateTime, you have no idea what the meaning of those values are. As a side note, you can still have a "Fire this event safely method while still using Action<T1, T2, T2... >".

Secondly, consistency implications. If you have a large system you're already working with, it's nearly always better to follow the way the rest of the system is designed unless you have an very good reason not too. If you have publicly facing events that need to be maintained, the ability to substitute derived classes can be important. Keep that in mind.

Thirdly, real life practice, I personally find that I tend to create a lot of one off events for things like property changes that I need to interact with (Particularly when doing MVVM with view models that interact with each other) or where the event has a single parameter. Most of the time these events take on the form of public event Action<[classtype], bool> [PropertyName]Changed; or public event Action SomethingHappened;. In these cases, there are two benefits. First, I get a type for the issuing class. If MyClass declares and is the only class firing the event, I get an explicit instance of MyClass to work with in the event handler. Secondly, for simple events such as property change events, the meaning of the parameters is obvious and stated in the name of the event handler and I don't have to create a myriad of classes for these kinds of events.

The simplest way to do that

  git fetch origin <branch> && git checkout <branch>

Example: I want to fetch uat branch from origin and switch to this as the current working branch.

   git fetch origin uat && git checkout uat

I created a event based solution based on Bjorn Tipling's answer:

(function(doc){
    'use strict';

    window.onscroll = function (event) {
        if (isEndOfElement(doc.body)){
            sendNewEvent('end-of-page-reached');
        }
    };

    function isEndOfElement(element){
        //visible height + pixel scrolled = total height 
        return element.offsetHeight + element.scrollTop >= element.scrollHeight;
    }

    function sendNewEvent(eventName){
        var event = doc.createEvent('Event');
        event.initEvent(eventName, true, true);
        doc.dispatchEvent(event);
    }
}(document));

And you use the event like this:

document.addEventListener('end-of-page-reached', function(){
    console.log('you reached the end of the page');
});

BTW: you need to add this CSS for javascript to know how long the page is

html, body {
    height: 100%;
}

just to extend Shankars and amals answers with simple unit testing:

/**
 *
 * workaround HTTPS problems with file_get_contents
 *
 * @param $url
 * @return boolean|string
 */
function curl_get_contents($url)
{
    $data = FALSE;
    if (filter_var($url, FILTER_VALIDATE_URL))
    {
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        $data = curl_exec($ch);
        curl_close($ch);
    }
    return $data;
}
// then in the unit tests:
public function test_curl_get_contents()
{
    $this->assertFalse(curl_get_contents(NULL));
    $this->assertFalse(curl_get_contents('foo'));
    $this->assertTrue(strlen(curl_get_contents('https://www.google.com')) > 0);
}

Below Test Init will also do the job.

[TestInitialize]
public void TestInit()
{
  HttpContext.Current = new HttpContext(new HttpRequest(null, "http://tempuri.org", null), new HttpResponse(null));
  YourControllerToBeTestedController = GetYourToBeTestedController();
}

You can do it in one line of code:

Log.d("intent URI", intent.toUri(0));

It outputs something like:

"#Intent;action=android.intent.action.MAIN;category=android.intent.category.LAUNCHER;launchFlags=0x10a00000;component=com.mydomain.myapp/.StartActivity;sourceBounds=12%20870%20276%201167; l.profile=0; end"

At the end of this string (the part that I bolded) you can find the list of extras (only one extra in this example).

This is according to the toUri documentation: "The URI contains the Intent's data as the base URI, with an additional fragment describing the action, categories, type, flags, package, component, and extras."

This is only a warning: your code still works, but probably won't work in the future as the method is deprecated. See the relevant source of Chromium and corresponding patch.

This has already been recognised and fixed in jQuery 1.11 (see here and here).

By using exploits or on badly configured servers it could be possible to download your PHP source. You could however either obfuscate and/or encrypt your code (using Zend Guard, Ioncube or a similar app) if you want to make sure your source will not be readable (to be accurate, obfuscation by itself could be reversed given enough time/resources, but I haven't found an IonCube or Zend Guard decryptor yet...).

Add sudo to your command line, like:

$ sudo firebase init

For anyone stumbling on this question, here is the answer if you are doing C++: You can check in your cpp code for vs version like the example bellow which links against a library based on vs version being 2015 or higher:

#if (_MSC_VER > 1800)
#pragma comment (lib, "legacy_stdio_definitions.lib")
#endif

This is done at link time and no extra run-time cost.

You Just need to subtract one day from today's date. In Python datetime.timedelta object lets you create specific spans of time as a timedelta object.

datetime.timedelta(1) gives you the duration of "one day" and is subtractable from a datetime object. After you subtracted the objects you can use datetime.strftime in order to convert the result --which is a date object-- to string format based on your format of choice:

>>> from datetime import datetime, timedelta
>>> yesterday = datetime.now() - timedelta(1)

>>> type(yesterday)                                                                                                                                                                                    
>>> datetime.datetime    

>>> datetime.strftime(yesterday, '%Y-%m-%d')
'2015-05-26'

Note that instead of calling the datetime.strftime function, you can also directly use strftime method of datetime objects:

>>> (datetime.now() - timedelta(1)).strftime('%Y-%m-%d')
'2015-05-26'

As a function:

def yesterday(string=False):
    yesterday = datetime.now() - timedelta(1)
    if string:
        return yesterday.strftime('%Y-%m-%d')
    return yesterday

This, works for me:

var getBaseUrl = function (url) {_x000D_
  if (url) {_x000D_
    var parts = url.split('://');_x000D_
    _x000D_
    if (parts.length > 1) {_x000D_
      return parts[0] + '://' + parts[1].split('/')[0] + '/';_x000D_
    } else {_x000D_
      return parts[0].split('/')[0] + '/';_x000D_
    }_x000D_
  }_x000D_
};

This works for me, hacked it once to see if it is possible, but never actually used in my program (GUI is so much nicer):

import time
f = '%4i %%'
len_to_clear = len(f)+1
clear = '\x08'* len_to_clear
print 'Progress in percent:'+' '*(len_to_clear),
for i in range(123):
    print clear+f % (i*100//123),
    time.sleep(0.4)
raw_input('\nDone')

SELECT * FROM user_cons_columns WHERE table_name = 'table_name';

You receive this error because in C language you are not allowed to use initializers with variable length arrays. The error message you are getting basically says it all.

6.7.8 Initialization

...

3 The type of the entity to be initialized shall be an array of unknown size or an object type that is not a variable length array type.

If your $result variable is a string json like, you must use json_decode function to parse it as an object or array:

$result = '{"Cancelled":false,"MessageID":"402f481b-c420-481f-b129-7b2d8ce7cf0a","Queued":false,"SMSError":2,"SMSIncomingMessages":null,"Sent":false,"SentDateTime":"\/Date(-62135578800000-0500)\/"}';
$json = json_decode($result, true);
print_r($json);

OUTPUT

Array
(
    [Cancelled] => 
    [MessageID] => 402f481b-c420-481f-b129-7b2d8ce7cf0a
    [Queued] => 
    [SMSError] => 2
    [SMSIncomingMessages] => 
    [Sent] => 
    [SentDateTime] => /Date(-62135578800000-0500)/
)

Now you can work with $json variable as an array:

echo $json['MessageID'];
echo $json['SMSError'];
// other stuff

You can do it server-side with nodejs.

Check out the popular Nodemailer package. There are plenty of transports and plugins for integrating with services like AWS SES and SendGrid!

The following example uses SES transport (Amazon SES):

let nodemailer = require("nodemailer");
let aws = require("aws-sdk");
let transporter = nodemailer.createTransport({
  SES: new aws.SES({ apiVersion: "2010-12-01" })
});

If you want to declare an empty array of string type you can do that in 5 different way:-

var myArray: Array<String> = Array()
var myArray = [String]()
var myArray: [String] = []
var myArray = Array<String>()
var myArray:Array<String> = []

Array of any type :-

    var myArray: Array<AnyObject> = Array()
    var myArray = [AnyObject]()
    var myArray: [AnyObject] = []
    var myArray = Array<AnyObject>()
    var myArray:Array<AnyObject> = []

Array of Integer type :-

    var myArray: Array<Int> = Array()
    var myArray = [Int]()
    var myArray: [Int] = []
    var myArray = Array<Int>()
    var myArray:Array<Int> = []

[ngStyle]="{'opacity': is_mail_sent ? '0.5' : '1' }"

I am sharing our nodejs implementation of the solution as implemented by @Raymond Hettinger.

var crypto = require('crypto');
var s = 'she sells sea shells by the sea shore';
console.log(BigInt('0x' + crypto.createHash('sha1').update(s).digest('hex'))%(10n ** 8n));

CD returns an EXIT_FAILURE when the specified directory does not exist. And you got conditional processing symbols, so you could do like the below for this.

SET cd_backup=%cd%
(CD "%~1" && CD %cd_backup%) || GOTO Error

:Error
CD %cd_backup%

I was able to create an EntityManager with Hibernate and PostgreSQL purely using Java code (with a Spring configuration) the following:

@Bean
public DataSource dataSource() {
    final PGSimpleDataSource dataSource = new PGSimpleDataSource();

    dataSource.setDatabaseName( "mytestdb" );
    dataSource.setUser( "myuser" );
    dataSource.setPassword("mypass");

    return dataSource;
}

@Bean
public Properties hibernateProperties(){
    final Properties properties = new Properties();

    properties.put( "hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect" );
    properties.put( "hibernate.connection.driver_class", "org.postgresql.Driver" );
    properties.put( "hibernate.hbm2ddl.auto", "create-drop" );

    return properties;
}

@Bean
public EntityManagerFactory entityManagerFactory( DataSource dataSource, Properties hibernateProperties ){
    final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
    em.setDataSource( dataSource );
    em.setPackagesToScan( "net.initech.domain" );
    em.setJpaVendorAdapter( new HibernateJpaVendorAdapter() );
    em.setJpaProperties( hibernateProperties );
    em.setPersistenceUnitName( "mytestdomain" );
    em.setPersistenceProviderClass(HibernatePersistenceProvider.class);
    em.afterPropertiesSet();

    return em.getObject();
}

The call to LocalContainerEntityManagerFactoryBean.afterPropertiesSet() is essential since otherwise the factory never gets built, and then getObject() returns null and you are chasing after NullPointerExceptions all day long. >:-(

It then worked with the following code:

PageEntry pe = new PageEntry();
pe.setLinkName( "Google" );
pe.setLinkDestination( new URL( "http://www.google.com" ) );

EntityTransaction entTrans = entityManager.getTransaction();
entTrans.begin();
entityManager.persist( pe );
entTrans.commit();

Where my entity was this:

@Entity
@Table(name = "page_entries")
public class PageEntry {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long id;

    private String linkName;
    private URL linkDestination;

    // gets & setters omitted
}

Create a file named filesize.cmd (and put into folder C:\Windows\System32):

@echo %~z1

I think you don't have to use sub query in this scenario.You can directly left outer join the DEPRMNT table .

While using Left Outer Join ,don't use columns in the RHS table of the join in the where condition, you ll get wrong output

I'm late to the game, but an anonymous objects would do the trick:

[HttpGet]
public HttpResponseMessage Me(string hash)
{
    HttpResponseMessage httpResponseMessage;
    List<Something> somethings = ...

    var returnObjects = somethings.Select(x => new {
        Id = x.Id,
        OtherField = x.OtherField
    });

    httpResponseMessage = Request.CreateResponse(HttpStatusCode.OK, 
                                 new { result = true, somethings = returnObjects });

    return httpResponseMessage;
}

This is quite an old question so I've updated this answer to take the HTML 5 email type into account.

You don't actually need JavaScript for this at all with HTML 5; just use the email input type:

<input type="email" />

• If you want to make it mandatory, you can add the required parameter.

• If you want to add additional RegEx validation (limit to @foo.com email addresses for example), you can use the pattern parameter, e.g.:

  <input type="email" pattern="[email protected]" />
  

There's more information available on MozDev.

Original answer follows

First off - I'd recommend the email validator RegEx from Hexillion: http://hexillion.com/samples/

It's pretty comprehensive - :

^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$

I think you want a function in your JavaScript like:

function validateEmail(sEmail) {
  var reEmail = /^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$/;

  if(!sEmail.match(reEmail)) {
    alert("Invalid email address");
    return false;
  }

  return true;

}

In the HTML input you need to trigger the event with an onblur - the easy way to do this is to simply add something like:

<input type="text" name="email" onblur="validateEmail(this.value);" />

Of course that's lacking some sanity checks and won't do domain verification (that has to be done server side) - but it should give you a pretty solid JS email format verifier.

Note: I tend to use the match() string method rather than the test() RegExp method but it shouldn't make any difference.

Inverse of a matrix using python and numpy:

>>> import numpy as np
>>> b = np.array([[2,3],[4,5]])
>>> np.linalg.inv(b)
array([[-2.5,  1.5],
       [ 2. , -1. ]])

Not all matrices can be inverted. For example singular matrices are not Invertable:

>>> import numpy as np
>>> b = np.array([[2,3],[4,6]])
>>> np.linalg.inv(b)

LinAlgError: Singular matrix

Solution to singular matrix problem:

try-catch the Singular Matrix exception and keep going until you find a transform that meets your prior criteria AND is also invertable.

Intuition for why matrix inversion can't always be done; like in singular matrices:

Imagine an old overhead film projector that shines a bright light through film onto a white wall. The pixels in the film are projected to the pixels on the wall.

If I stop the film projection on a single frame, you will see the pixels of the film on the wall and I ask you to regenerate the film based on what you see. That's easy, you say, just take the inverse of the matrix that performed the projection. An Inverse of a matrix is the reversal of the projection.

Now imagine if the projector was corrupted, and I put a distorted lens in front of the film. Now multiple pixels are projected to the same spot on the wall. I asked you again to "undo this operation with the matrix inverse". You say: "I can't because you destroyed information with the lens distortion, I can't get back to where we were, because the matrix is either Singular or Degenerate."

A matrix that can be used to transform some data into other data is invertable only if the process can be reversed with no loss of information. If your matrix can't be inverted, perhaps you are defining your projection using a guess-and-check methodology rather than using a process that guarantees a non-corrupting transform.

If you're using a heuristic or anything less than perfect mathematical precision, then you'll have to define another process to manage and quarantine distortions so that programming by Brownian motion can resume.

This should work

if(!Directory.Exists(@"C:\MP_Upload")) {
    Directory.CreateDirectory(@"C:\MP_Upload");
}

SHOW TABLE STATUS WHERE Name = 'xxx'

This will give you (among other things) an Engine column, which is what you want.

If you use "hg remove b" against a file with "A" status, which means it has been added but not commited, Mercurial will respond:

  not removing b: file has been marked for add (use forget to undo)

This response is a very clear explication of the difference between remove and forget.

My understanding is that "hg forget" is for undoing an added but not committed file so that it is not tracked by version control; while "hg remove" is for taking out a committed file from version control.

This thread has a example for using hg remove against files of 7 different types of status.

"mm" means the "minutes" fragment of a date. For the "months" part, use "MM".

So, try to change the code to:

DateFormat df = new SimpleDateFormat("MM/dd/yyyy"); 
Date startDate = df.parse(startDateString);

Edit: A DateFormat object contains a date formatting definition, not a Date object, which contains only the date without concerning about formatting. When talking about formatting, we are talking about create a String representation of a Date in a specific format. See this example:

    import java.text.DateFormat;
    import java.text.SimpleDateFormat;
    import java.util.Date;

    public class DateTest {

        public static void main(String[] args) throws Exception {
            String startDateString = "06/27/2007";

            // This object can interpret strings representing dates in the format MM/dd/yyyy
            DateFormat df = new SimpleDateFormat("MM/dd/yyyy"); 

            // Convert from String to Date
            Date startDate = df.parse(startDateString);

            // Print the date, with the default formatting. 
            // Here, the important thing to note is that the parts of the date 
            // were correctly interpreted, such as day, month, year etc.
            System.out.println("Date, with the default formatting: " + startDate);

            // Once converted to a Date object, you can convert 
            // back to a String using any desired format.
            String startDateString1 = df.format(startDate);
            System.out.println("Date in format MM/dd/yyyy: " + startDateString1);

            // Converting to String again, using an alternative format
            DateFormat df2 = new SimpleDateFormat("dd/MM/yyyy"); 
            String startDateString2 = df2.format(startDate);
            System.out.println("Date in format dd/MM/yyyy: " + startDateString2);
        }
    }

Output:

Date, with the default formatting: Wed Jun 27 00:00:00 BRT 2007
Date in format MM/dd/yyyy: 06/27/2007
Date in format dd/MM/yyyy: 27/06/2007

Here is a function I came up with to do "round up". I used double Math.round to compensate for JavaScript's inaccurate multiplying, so 1.005 will be correctly rounded as 1.01.

function myRound(number, decimalplaces){
    if(decimalplaces > 0){
        var multiply1 = Math.pow(10,(decimalplaces + 4));
        var divide1 = Math.pow(10, decimalplaces);
        return Math.round(Math.round(number * multiply1)/10000 )/divide1;
    }
    if(decimalplaces < 0){
        var divide2 = Math.pow(10, Math.abs(decimalplaces));
        var multiply2 = Math.pow(10, Math.abs(decimalplaces));
        return Math.round(Math.round(number / divide2) * multiply2);
    }
    return Math.round(number);
}

If you want to print the last 10 lines, use

tail(dataset, 10)

for the first 10, you could also do

head(dataset, 10)

The CGRectZero constant is equal to a rectangle at position (0,0) with zero width and height. This is fine to use, and actually preferred, if you use AutoLayout, since AutoLayout will then properly place the view.

But, I expect you do not use AutoLayout. So the most simple solution is to specify the size of the custom view by providing a frame explicitly:

customView = MyCustomView(frame: CGRect(x: 0, y: 0, width: 200, height: 50))
self.view.addSubview(customView)

Note that you also need to use addSubview otherwise your view is not added to the view hierarchy.

I found that the cleanest way to do this is to create a custom TwigExtension and override its getGlobals() method. Rather than using $_SESSION, it's also better to use Symfony's Session class since it handles automatically starting/stopping the session.

I've got the following extension in /src/AppBundle/Twig/AppExtension.php:

<?php    
namespace AppBundle\Twig;

use Symfony\Component\HttpFoundation\Session\Session;

class AppExtension extends \Twig_Extension {

    public function getGlobals() {
        $session = new Session();
        return array(
            'session' => $session->all(),
        );
    }

    public function getName() {
        return 'app_extension';
    }
}

Then add this in /app/config/services.yml:

services:
    app.twig_extension:
        class: AppBundle\Twig\AppExtension
        public: false
        tags:
            - { name: twig.extension }

Then the session can be accessed from any view using:

{{ session.my_variable }}

Simple solution:

document.onpaste = function(e) {
    var pasted = e.clipboardData.getData('Text');
    console.log(pasted)
}

This problem happening when your build tool is not set to do restore on projects set to use PackageReference vs packages.config and mostly affect Net Core and Netstandard new style projects.

When you open Visual Studio and build, it resolves this for you. But if you use automation, CLI tools, you see this issue.

Many solutions are offered here. But all you need to remember, you need to force restore. In some instances you use dotnet restore before build. If you build using MsBuild just add /t:Restore switch to your command.

Bottom line, you need to see why restoring can't be activated. Either bad nuget source or missing restore action, or outdated nuget.exe, or all of the above.

This is how I do it, with a README.md file in each directory:

/data/*
!/data/README.md

!/data/input/
/data/input/*
!/data/input/README.md

!/data/output/
/data/output/*
!/data/output/README.md

You can also apply TR classes: info, error, warning, or success.

You can swap out instances of NULL with a different value to sort them first (like 0 or -1) or last (a large number or a letter)...

SELECT field1, IF(field2 IS NULL, 9999, field2) as ordered_field2
  FROM tablename
 WHERE visible = 1
 ORDER BY ordered_field2 ASC, id DESC

On the last entry; this is another trick:

SELECT AUTO_INCREMENT FROM information_schema.tables WHERE table_schema = ... and table_name = ...

No, find() method is not a member of std::list. Instead, use std::find from <algorithm>

    std :: list < int > l;
    std :: list < int > :: iterator pos;

    l.push_back(1);
    l.push_back(2);
    l.push_back(3);
    l.push_back(4);
    l.push_back(5);
    l.push_back(6);

    int elem = 3;   
    pos = find(l.begin() , l.end() , elem);
    if(pos != l.end() )
        std :: cout << "Element is present. "<<std :: endl;
    else
        std :: cout << "Element is not present. "<<std :: endl;

Invoke it from the shell, with an argument like /? or --help. Those are the usual help switches.

Not sure if this is valid but it worked for me.

The code :

<div style='position:relative;background-color:#000000;width:600px;height:30px;border:solid;'>_x000D_
  <p style='display:inline;color:#ffffff;float:left;'> Whatever </p>     _x000D_
  <a style='position:absolute;top:0px;left:0px;width:100%;height:100%;display:inline;' href ='#'></a>_x000D_
</div>

just a tip,

try to use JodaTime instead of java,util.Date it is much more powerfull and it has a method toString("") that you can pass the format you want like toString("yyy-MM-dd HH:mm:ss");

http://joda-time.sourceforge.net/

As you become more experienced with using Perl, you'll find that there are fewer and fewer occasions when you need to run shell commands. For example, one way to get a list of files is to use Perl's built-in glob function. If you want the list in sorted order you could combine it with the built-in sort function. If you want details about each file, you can use the stat function. Here's an example:

#!/usr/bin/perl

use strict;

Technically C# Extension have no equivalent in Java. But if you do want to implement such functions for a cleaner code and maintainability, you have to use Manifold framework.

package extensions.java.lang.String;

import manifold.ext.api.*;

@Extension
public class MyStringExtension {

  public static void print(@This String thiz) {
    System.out.println(thiz);
  }

  @Extension
  public static String lineSeparator() {
    return System.lineSeparator();
  }
}

I'm on Linux and get same result for both of these approaches:

@Test
public void aaa()
{
    System.err.println(Paths.get("").toAbsolutePath().toString());

    System.err.println(System.getProperty("user.dir"));
}

Not sure why nobody mentioned this : when you run the installation command from the official site, in the final lines you would see something like below, and you need to follow the ==> Next steps:

This is for bash shell. You will see different steps for every different shell, but the source of the steps are same.

I want to add that when using Npgsql (data provider for PostgreSQL), arrays and lists of primitive types are actually supported:

In applied usage for the Asynchronous IO coroutine, yield from has a similar behavior as await in a coroutine function. Both of which is used to suspend the execution of coroutine.

• yield from is used by the generator-based coroutine.

• await is used for async def coroutine. (since Python 3.5+)

For Asyncio, if there's no need to support an older Python version (i.e. >3.5), async def/await is the recommended syntax to define a coroutine. Thus yield from is no longer needed in a coroutine.

But in general outside of asyncio, yield from <sub-generator> has still some other usage in iterating the sub-generator as mentioned in the earlier answer.

I had this issue with MacOS. I had to uncheck "use download cache" under Android SDK Manager preferences. This worked. I also recreated the cache folder and set my user as the owner then check user download cache. This also worked.

I had similar issues with the threads being started in Spring bean. These threads were not closing properly after i called executor.shutdownNow() in @PreDestroy method. So the solution for me was to let the thread finsih with IO already started and start no more IO, once @PreDestroy was called. And here is the @PreDestroy method. For my application the wait for 1 second was acceptable.

@PreDestroy
    public void beandestroy() {
        this.stopThread = true;
        if(executorService != null){
            try {
                // wait 1 second for closing all threads
                executorService.awaitTermination(1, TimeUnit.SECONDS);
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
            }
        }
    }

Here I have explained all the issues faced while trying to close threads.http://programtalk.com/java/executorservice-not-shutting-down/

There isn't really a way to edit files in-place. What you usually do when you can get away with it (i.e. if the files are not too big) is, you read the file into memory (File.read), perform your substitutions on the read string (String#gsub) and then write the changed string back to the file (File.open, File#write).

If the files are big enough for that to be unfeasible, what you need to do, is read the file in chunks (if the pattern you want to replace won't span multiple lines then one chunk usually means one line - you can use File.foreach to read a file line by line), and for each chunk perform the substitution on it and append it to a temporary file. When you're done iterating over the source file, you close it and use FileUtils.mv to overwrite it with the temporary file.

If you came across the error when tried to generate a jks file (keystore), so try adding

/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home/bin/keytool

before running the command, like so:

/Applications/Android\ Studio.app/Contents/jre/jdk/Contents/Home/bin/keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key

just install the database driver:

apt-get install php5-pgsql php5-mysql php5-sqlite ... and so on ...

and be happy!

For a standard shell (without bashisms) using only builtins:

uppers=ABCDEFGHIJKLMNOPQRSTUVWXYZ
lowers=abcdefghijklmnopqrstuvwxyz

lc(){ #usage: lc "SOME STRING" -> "some string"
    i=0
    while ([ $i -lt ${#1} ]) do
        CUR=${1:$i:1}
        case $uppers in
            *$CUR*)CUR=${uppers%$CUR*};OUTPUT="${OUTPUT}${lowers:${#CUR}:1}";;
            *)OUTPUT="${OUTPUT}$CUR";;
        esac
        i=$((i+1))
    done
    echo "${OUTPUT}"
}

And for upper case:

uc(){ #usage: uc "some string" -> "SOME STRING"
    i=0
    while ([ $i -lt ${#1} ]) do
        CUR=${1:$i:1}
        case $lowers in
            *$CUR*)CUR=${lowers%$CUR*};OUTPUT="${OUTPUT}${uppers:${#CUR}:1}";;
            *)OUTPUT="${OUTPUT}$CUR";;
        esac
        i=$((i+1))
    done
    echo "${OUTPUT}"
}

I agree with other posters that Xcode as a developing environment should include an easy way to debug variables. Well, good news, there IS one!

After searching and not finding a simple answer/tutorial on how to debug variables in Xcode I went to explore with Xcode itself and found this (at least for me) very useful discovery.

How to easily debug your variables in Xcode 4.6.3

In the main screen of Xcode make sure to see the bottom Debug Area by clicking the upper-right corner button showed in the screenshot.

Now set a Breakpoint – the line in your code where you want your program to pause, by clicking the border of your Code Area.

Now in the Debug Area look for this buttons and click the one in the middle. You will notice your area is now divided in two.

Now run your application.

When the first Breakpoint is reached during the execution of your program you will see on the left side all your variables available at that breakpoint.

You can expand the left arrows on the variable for a greater detail. And even use the search field to isolate that variable you want and see it change on real time as you "Step into" the scope of the Breakpoint.

On the right side of your Debug Area you can send to print the variables as you desire using the mouse's right-button click over the desired variable.

As you can see, that contextual menu is full of very interesting debugging options. Such as Watch that has been already suggested with typed commands or even Edit Value… that changes the runtime value of your variable!

It seems the original author has found their solution, but for anyone else who gets here looking to add actual custom headers, if you have access to mod the generated Protocol code you can override GetWebRequest:

protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
  System.Net.WebRequest request = base.GetWebRequest(uri);
  request.Headers.Add("myheader", "myheader_value");
  return request;
}

Make sure you remove the DebuggerStepThroughAttribute attribute if you want to step into it.

See under the heading One Operating System Running On Multiple Platforms where it states:

Most of the source code for Windows NT is written in C or C++.

Take a look at the Cookie Plugin for jQuery.

This works:

$('body').append($("<script>alert('Hi!');<\/script>")[0]);

It seems like jQuery is doing something clever with scripts so you need to append the html element rather than jQuery object.

I'm going to attempt to explain this without making any mistakes, but I'm betting this will attract a clarification or two in the comments.

A data frame is a list. When you subset a data frame using the name of a column and [, what you're getting is a sublist (or a sub data frame). If you want the actual atomic column, you could use [[, or somewhat confusingly (to me) you could do aframe[,2] which returns a vector, not a sublist.

So try running this sequence and maybe things will be clearer:

avector <- as.vector(aframe['a2'])
class(avector) 

avector <- aframe[['a2']]
class(avector)

avector <- aframe[,2]
class(avector)

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

I think one of the original questions here was not answered. I believe that vanilla eval() is not used because then angular apps would not work as Chrome apps, which explicitly prevent eval() from being used for security reasons.

You need to initialize whatever members you have in your struct, e.g.:

struct MyStruct {
  private:
    int someInt_;
    float someFloat_;

  public:
    MyStruct(): someInt_(0), someFloat_(1.0) {} // Initializer list will set appropriate values

};

I am siteConfiguration class for calling all my appSetting like this way. I share it if it will help anyone.

add the following code at the "web.config"

<configuration>
   <configSections>
     <!-- some stuff omitted here -->
   </configSections>
   <appSettings>
      <add key="appKeyString" value="abc" />
      <add key="appKeyInt" value="123" />  
   </appSettings>
</configuration>

Now you can define a class for getting all your appSetting value. like this

using System; 
using System.Configuration;
namespace Configuration
{
   public static class SiteConfigurationReader
   {
      public static String appKeyString  //for string type value
      {
         get
         {
            return ConfigurationManager.AppSettings.Get("appKeyString");
         }
      }

      public static Int32 appKeyInt  //to get integer value
      {
         get
         {
            return ConfigurationManager.AppSettings.Get("appKeyInt").ToInteger(true);
         }
      }

      // you can also get the app setting by passing the key
      public static Int32 GetAppSettingsInteger(string keyName)
      {
          try
          {
            return Convert.ToInt32(ConfigurationManager.AppSettings.Get(keyName));
        }
        catch
        {
            return 0;
        }
      }
   }
}

Now add the reference of previous class and to access a key call like bellow

string appKeyStringVal= SiteConfigurationReader.appKeyString;
int appKeyIntVal= SiteConfigurationReader.appKeyInt;
int appKeyStringByPassingKey = SiteConfigurationReader.GetAppSettingsInteger("appKeyInt");

None of the solutions worked for me in Firefox.

The following solution changes the border style on focus for Firefox and sets the outline to none for other browsers.

I've effectively made the focus border go from a 3px blue glow to a border style that matches the text area border. Here's some border styles:

Dashed border (border 2px dashed red):

No border! (border 0px):

Textarea border (border 1px solid gray):

Here is the code:

input:focus, textarea:focus {_x000D_
    outline: none; /** For Safari, etc **/_x000D_
    border:1px solid gray; /** For Firefox **/_x000D_
}_x000D_
_x000D_
#textarea  {_x000D_
  position:absolute;_x000D_
  top:10px;_x000D_
  left:10px;_x000D_
  right:10px;_x000D_
  width:calc(100% - 20px);_x000D_
  height:160px;_x000D_
  display:inline-block;_x000D_
  margin-top:-0.2em;_x000D_
}

<textarea id="textarea">yo</textarea>

import io, pygame, zipfile
archive = zipfile.ZipFile('images.zip', 'r')

# read bytes from archive
img_data = archive.read('img_01.png')

# create a pygame-compatible file-like object from the bytes
bytes_io = io.BytesIO(img_data)

img = pygame.image.load(bytes_io)

I was trying to figure this out for myself just now and thought this might be useful for anyone who comes across this question in the future.

I know this a very much late reply but I saw this query recently And found a working scenario,

OnClick of Submit use the below code:

 $('#Submit').click(function ()
 { $(this).html('<img src="icon-loading.gif" />'); // A GIF Image of Your choice
 return false });

To Stop the Gif use the below code:

$('#Submit').ajaxStop();

The accepted answer has a couple of shortcomings:

• Don't target IDs in your JavaScript code. Use classes and data attributes to avoid repeating your code.
• It is good practice to hide with CSS on load rather than with JavaScript—to support non-JavaScript users, and prevent a show-hide flicker on load.

Considering the above, your options could even have different values, but toggle the same class:

<select class="div-toggle" data-target=".my-info-1">
  <option value="orange" data-show=".citrus">Orange</option>
  <option value="lemon" data-show=".citrus">Lemon</option>
  <option value="apple" data-show=".pome">Apple</option>
  <option value="pear" data-show=".pome">Pear</option>
</select>

<div class="my-info-1">
  <div class="citrus hide">Citrus is...</div>
  <div class="pome hide">A pome is...</div>
</div>

jQuery:

$(document).on('change', '.div-toggle', function() {
  var target = $(this).data('target');
  var show = $("option:selected", this).data('show');
  $(target).children().addClass('hide');
  $(show).removeClass('hide');
});
$(document).ready(function(){
    $('.div-toggle').trigger('change');
});

CSS:

.hide {
  display: none;
}

Here's a JSFiddle to see it in action.

Try this:

bitmap.compress(Bitmap.CompressFormat.PNG, quality, outStream);

See this

You can put an apostrophe in a single quoted JavaScript string by escaping it with a backslash, like so:

theAnchorText = 'I\'m home';

On linux systems:

~/.sqldeveloper/system<sqldeveloper_version>/o.jdeveloper.db.connection/connections.xml

The answers seems a bit over complicated. I hope I didn't misunderstand the question.

If you simply want to open a fancy box from a click to an "A" tag. Just set your html to

<a id="my_fancybox" href="#contentdiv">click me</a>

The contents of your box will be inside of a div with id "contentdiv" and in your javascript you can initialize fancybox like this:

$('#my_fancybox').fancybox({
    'autoScale': true,
    'transitionIn': 'elastic',
    'transitionOut': 'elastic',
    'speedIn': 500,
    'speedOut': 300,
    'autoDimensions': true,
    'centerOnScroll': true,
});

This will show a fancybox containing "contentdiv" when your anchor tag is clicked.

This should print the list of positions without the -1 at the end that Peter Lawrey's solution has had.

int index = word.indexOf(guess);
while (index >= 0) {
    System.out.println(index);
    index = word.indexOf(guess, index + 1);
}

It can also be done as a for loop:

for (int index = word.indexOf(guess);
     index >= 0;
     index = word.indexOf(guess, index + 1))
{
    System.out.println(index);
}

[Note: if guess can be longer than a single character, then it is possible, by analyzing the guess string, to loop through word faster than the above loops do. The benchmark for such an approach is the Boyer-Moore algorithm. However, the conditions that would favor using such an approach do not seem to be present.]

<html>
<head>
<script>
function updateTextarea(element)
{
document.getElementById(element).innerText = document.getElementById("ment").value;
}
</script>
</head>
<body>

<input type="text" value="Enter your text here." id = "ment" style = " border: 1px solid grey; margin-bottom: 4px;"  

onKeyUp="updateTextarea('myDiv')" />

<br>

<textarea id="myDiv" ></textarea>

</body>
</html>

Just a matter of the right google search:

data = dat_1.append(dat_2)
data = data.groupby(data.index).sum()

In Vuetify 2.x, v-layout and v-flex are replaced by v-row and v-col respectively. To center the content both vertically and horizontally, we have to instruct the v-row component to do it:

<v-container fill-height>
    <v-row justify="center" align="center">
        <v-col cols="12" sm="4">
            Centered both vertically and horizontally
        </v-col>
    </v-row>
</v-container>

• align="center" will center the content vertically inside the row
• justify="center" will center the content horizontally inside the row
• fill-height will center the whole content compared to the page.

1st way is to use props

<Row id = "someRandomID">

Wherein, in the Definition, you may just go

const Row = props  => {
 div id = {props.id}
}

The same could be done with class, replacing id with className in the above example.

You might as well use react-html-id, that is an npm package. This is an npm package that allows you to use unique html IDs for components without any dependencies on other libraries.

Ref: react-html-id

Peace.

UPDATE: Thanks to Bruno Lopes. If several ip addresses could come then need to use this method:

    private string GetUserIP()
    {
        string ipList = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

        if (!string.IsNullOrEmpty(ipList))
        {
            return ipList.Split(',')[0];
        }

        return Request.ServerVariables["REMOTE_ADDR"];
    }

Also, from ojdbc14 to ojdbc6, several types (e.g., OracleResultSet, OracleStatement) moved from package oracle.jdbc.driver to oracle.jdbc.

In case anyone is still looking for this functionality: I made an Android library that has this ability and much more, called ExpandableFab (https://github.com/nambicompany/expandable-fab).

The Material Design spec refers to this functionality as 'Speed Dial' and ExpandableFab implements it along with many additional features.

Nearly everything is customizable (colors, text, size, placement, margins, animations and more) and optional (don't need an Overlay, or FabOptions, or Labels, or icons, etc). Every property can be accessed or set through XML layouts or programmatically - whatever you prefer.

Written 100% in Kotlin but comes with full JavaDoc and KDoc (published API is well documented). Also comes with an example app so you can see different use cases with 0 coding.

Github: https://github.com/nambicompany/expandable-fab

To disable bundling and minification just put this your .aspx file (this will disable optimization even if debug=true in web.config)

vb.net:

System.Web.Optimization.BundleTable.EnableOptimizations = false

c#.net

System.Web.Optimization.BundleTable.EnableOptimizations = false;

If you put EnableOptimizations = true this will bundle and minify even if debug=true in web.config

I have used the following logic in SSRS reports.

BUS_DATE = 17-09-2013

X=DATEADD(MONTH,-1,BUS_DATE) = 17-08-2013

Y=DAY(BUS_DATE)=17

first_date = DATEADD(DAY,-Y+1,X)=01-08-2013

last_date  = DATEADD(DAY,-Y,BUS_DATE)=31-08-2013

Using http.createServer is very low-level and really not useful for creating web applications as-is.

A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express.

When you have, you can create a basic application to handle your form:

var express = require('express');
var bodyParser = require('body-parser');
var app     = express();

//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true })); 

//app.use(express.bodyParser());

app.post('/myaction', function(req, res) {
  res.send('You sent the name "' + req.body.name + '".');
});

app.listen(8080, function() {
  console.log('Server running at http://127.0.0.1:8080/');
});

You can make your form point to it using:

<form action="http://127.0.0.1:8080/myaction" method="post">

The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html). You could use Express to also serve static content, like index.html, using the express.static middleware.

Create a UIKeyboardListener when you know the keyboard is not visible, for example by calling [UIKeyboardListener shared] from applicationDidFinishLaunching.

@implementation UIKeyboardListener

+ (UIKeyboardListener) shared {
    static UIKeyboardListener sListener;    
    if ( nil == sListener ) sListener = [[UIKeyboardListener alloc] init];

    return sListener;
}

-(id) init {
    self = [super init];

    if ( self ) {

Some of it is native, the rest is available through libraries.

For example Datejs is a good international date library.

For the rest, it's just about language translation, and JavaScript is natively Unicode compatible (as well as all major browsers).

Invoke-WebRequest can download HTTP, HTTPS, and FTP links.

$source = 'ftp://Blah.com/somefile.txt'
$target = 'C:\Users\someuser\Desktop\BlahFiles\somefile.txt'
$password = Microsoft.PowerShell.Security\ConvertTo-SecureString -String 'mypassword' -AsPlainText -Force
$credential = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList myuserid, $password

# Download
Invoke-WebRequest -Uri $source -OutFile $target -Credential $credential -UseBasicParsing

Since the cmdlet uses IE parsing you may need the -UseBasicParsing switch. Test to make sure.

Since there are limited real answers I'll share this workaround. For really simple cases like your example you do it backwards...

From this

1
2
3
4
5

Replace \r\n with " />\r\n<row id=" and you'll get 90% of the way there

1" />
<row id="2" />
<row id="3" />
<row id="4" />
<row id="5

Or is a similar fashion you can hack about data with excel/spreadsheet. Just split your original data into columns and manipulate values as you require.

|   <row id="   |   1   |   " />    |
|   <row id="   |   1   |   " />    |
|   <row id="   |   1   |   " />    |
|   <row id="   |   1   |   " />    |
|   <row id="   |   1   |   " />    |

Obvious stuff but it may help someone doing the odd one-off hack job to save a few key strokes.

The obvious subtext of this question is:

why can't you just use == to check if two strings are the same?

Perl doesn't have distinct data types for text vs. numbers. They are both represented by the type "scalar". Put another way, strings are numbers if you use them as such.

if ( 4 == "4" ) { print "true"; } else { print "false"; }
true

if ( "4" == "4.0" ) { print "true"; } else { print "false"; }
true

print "3"+4
7

Since text and numbers aren't differentiated by the language, we can't simply overload the == operator to do the right thing for both cases. Therefore, Perl provides eq to compare values as text:

if ( "4" eq "4.0" ) { print "true"; } else { print "false"; }
false

if ( "4.0" eq "4.0" ) { print "true"; } else { print "false"; }
true

In short:

• Perl doesn't have a data-type exclusively for text strings
• use == or !=, to compare two operands as numbers
• use eq or ne, to compare two operands as text

There are many other functions and operators that can be used to compare scalar values, but knowing the distinction between these two forms is an important first step.

I checked the mysql log in the cd /var/lib/mysql directory in the mysql-error.log file with the command tail -n 200 mysql-error.log and identified ([ERROR]) that there were two wrong variables in my.ini, after I removed them I was able to start the mysql service with the command /etc/init.d/mysql start or service mysql start

There's no need to use replace for this.

What you have is a encoded string (using the string_escape encoding) and you want to decode it:

>>> s = r"Escaped\nNewline"
>>> print s
Escaped\nNewline
>>> s.decode('string_escape')
'Escaped\nNewline'
>>> print s.decode('string_escape')
Escaped
Newline
>>> "a\\nb".decode('string_escape')
'a\nb'

In Python 3:

>>> import codecs
>>> codecs.decode('\\n\\x21', 'unicode_escape')
'\n!'

Just a supplement to the first post: use a user defined union type to store the pthread_t:

union tid {
    pthread_t pthread_id;
    unsigned long converted_id;
};

Whenever you want to print pthread_t, create a tid and assign tid.pthread_id = ..., then print tid.converted_id.

To see all keys of Jsonobject use this

    String JSON = "{\"LanguageLevels\":{\"1\":\"Pocz\\u0105tkuj\\u0105cy\",\"2\":\"\\u015arednioZaawansowany\",\"3\":\"Zaawansowany\",\"4\":\"Ekspert\"}}\n";
    JSONObject obj = new JSONObject(JSON);
    Iterator iterator = obj.keys();
    String key = null;
    while (iterator.hasNext()) {
        key = (String) iterator.next();
        System.out.pritnln(key);
    } 

Add compat library compilation to the build.gradle file:

compile 'com.android.support:appcompat-v7:19.+'

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

For merging first branch to second one:

on first branch: git merge secondBranch

on second branch: Move to first branch-> git checkout firstBranch-> git merge secondBranch

A few of the options are deprecated as of today. So watch out for those.

If you try <input onkeypress="blockSpecialCharacters(event)" />, an IDE like WebStorm will slash out event and tell you:

Deprecated symbol used, consults docs for better alternative

Then when you get to the JavaScript, console.log(e.keyCode) will also give keyCode and say:

Deprecated symbol used, consults docs for better alternative

Anyways I did it using jQuery.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.js"></script>

<input id="theInput" />

<script>
    function blockSpecialCharacters(e) {
            let key = e.key;
            let keyCharCode = key.charCodeAt(0);

            // 0-9
            if(keyCharCode >= 48 && keyCharCode <= 57) {
                return key;
            }
            // A-Z
            if(keyCharCode >= 65 && keyCharCode <= 90) {
                return key;
            }
            // a-z
            if(keyCharCode >= 97 && keyCharCode <= 122) {
                return key;
            }

            return false;
    }

    $('#theInput').keypress(function(e) {
        blockSpecialCharacters(e);
    });
</script>

The latest version of angular is only setup for evergreen browsers by default...

The current setup is for so-called "evergreen" browsers; the last versions of browsers that automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera), Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
This also includes firefox, although not mentioned.

See here for more information on browser support along with a list of suggested polyfills for specific browsers. https://angular.io/guide/browser-support#polyfill-libs

To achieve this, go into polyfills.ts (in the src folder by default) and just uncomment the following imports:

/***************************************************************************************************
 * BROWSER POLYFILLS
 */

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
 import 'core-js/es6/symbol';
 import 'core-js/es6/object';
 import 'core-js/es6/function';
 import 'core-js/es6/parse-int';
 import 'core-js/es6/parse-float';
 import 'core-js/es6/number';
 import 'core-js/es6/math';
 import 'core-js/es6/string';
 import 'core-js/es6/date';
 import 'core-js/es6/array';
 import 'core-js/es6/regexp';
 import 'core-js/es6/map';
 import 'core-js/es6/set';

Note that the comment is literally in the file, so this is easy to find.

If you are still having issues, you can downgrade the target property to es5 in tsconfig.json as @MikeDub suggested. What this does is change the compilation output of any es6 definitions to es5 definitions. For example, fat arrow functions (()=>{}) will be compiled to anonymous functions (function(){}). You can find a list of es6 supported browsers here.

Notes

• I was asked in the comments by @jackOfAll whether IE11 polyfills are loaded even if the user is in an evergreen browser which doesn't need them. The answer is, yes they are! The inclusion of the IE11 polyfills will take your polyfill file from ~162KB to ~258KB as of Aug 8 '17. I have invested in trying to solve this however it does not seem possible at this time.

• If you are getting errors in IE10 and below, go into you package.json and downgrade webpack-dev-server to 2.7.1 specifically. Versions higher than this no longer support "older" IE versions.

In C, declaring your enum the first way allows you to use it like so:

TokenType my_type;

If you use the second style, you'll be forced to declare your variable like this:

enum TokenType my_type;

As mentioned by others, this doesn't make a difference in C++. My guess is that either the person who wrote this is a C programmer at heart, or you're compiling C code as C++. Either way, it won't affect the behaviour of your code.

I found that, I am using a different InstallUtil from my target .NET Framework. I am building a .NET Framework 4.5, meanwhile the error occured if I am using the .NET Framework 2.0 release. Having use the right InstallUtil for my target .NET Framework, solved this problem!
