I got this error because I found out that I referenced jQuery twice.

The first time: on the master page (_Layout.cshtml) in ASP.NET MVC, and then again on one current page so I commented out the one on the master page.

If you are using ASP.NET MVC this snippet could help you

@*@Scripts.Render("~/bundles/jquery")*@//comment this line 
@Scripts.Render("~/bundles/bootstrap")
@RenderSection("scripts", required: false)

and in the current page I added these lines

<script src="~/scripts/jquery-1.10.2.js"></script>

<!-- #region datatables files -->
<link rel="stylesheet" type="text/css" href="//cdn.datatables.net/1.10.12/css/jquery.dataTables.min.css" />
<script src="//cdn.datatables.net/1.10.12/js/jquery.dataTables.min.js"></script>
<!-- #endregion -->

Hope this help you even if don't use ASP.NET MVC

If the image is in your resources folder and its build action is set to Resource. You can reference the image in XAML as follows:

"pack://application:,,,/Resources/Search.png"

Assuming you do not have any folder structure under the Resources folder and it is an application. For example I use:

ImageSource="pack://application:,,,/Resources/RibbonImages/CloseButton.png"

when I have a folder named RibbonImages under Resources folder.

You do not have many complex methods to import a python file from one folder to another. Just create a __init__.py file to declare this folder is a python package and then go to your host file where you want to import just type

from root.parent.folder.file import variable, class, whatever

The magic method __getitem__ is basically used for accessing list items, dictionary entries, array elements etc. It is very useful for a quick lookup of instance attributes.

Here I am showing this with an example class Person that can be instantiated by 'name', 'age', and 'dob' (date of birth). The __getitem__ method is written in a way that one can access the indexed instance attributes, such as first or last name, day, month or year of the dob, etc.

import copy

# Constants that can be used to index date of birth's Date-Month-Year
D = 0; M = 1; Y = -1

class Person(object):
    def __init__(self, name, age, dob):
        self.name = name
        self.age = age
        self.dob = dob

    def __getitem__(self, indx):
        print ("Calling __getitem__")
        p = copy.copy(self)

        p.name = p.name.split(" ")[indx]
        p.dob = p.dob[indx] # or, p.dob = p.dob.__getitem__(indx)
        return p

Suppose one user input is as follows:

p = Person(name = 'Jonab Gutu', age = 20, dob=(1, 1, 1999))

With the help of __getitem__ method, the user can access the indexed attributes. e.g.,

print p[0].name # print first (or last) name
print p[Y].dob  # print (Date or Month or ) Year of the 'date of birth'

You could also use React's useState hook to declare local state for a function component. The initial state of the variable toggled has been passed as an argument to the method .useState.

import { render } from 'react-dom';
import React from "react";

type Props = {
  text: string,
  onClick(event: React.MouseEvent<HTMLButtonElement>): void,
};

export function HelloWorldButton(props: Props) {
  const [toggled, setToggled] = React.useState(false); // returns a stateful value, and a function to update it
  return <button
  onClick={(event) => {
    setToggled(!toggled);
    props.onClick(event);
  }}
  >{props.text} (toggled: {toggled.toString()})</button>;
}


render(<HelloWorldButton text='Hello World' onClick={() => console.log('clicked!')} />, document.getElementById('root'));

https://stackblitz.com/edit/react-ts-qga3vc

For the original see doublep answer:

Foo[] a = x.toArray(new Foo[x.size()]);

As for the update:

int i = 0;
Bar[] bars = new Bar[fooCollection.size()];
for( Foo foo : fooCollection ) { // where fooCollection is Collection<Foo>
    bars[i++] = new Bar(foo);
}    

The way I fixed similar issue was by adding Month to my SELECT portion

Month DATEADD(day,Created_Date,'1971/12/31') As Month

and than I added WHERE statement

Month DATEADD(day,Created_Date,'1971/12/31') = month(getdate())-1

I want to add the important hint that converting a project like this can have side effects which are noticeable when you have a larger project. This is due the fact that Intellij Idea (2017) takes some important settings only from the pom.xml then which can lead to some confusion, following sections are affected at least:

1. Annotation settings are changed for the modules
2. Compiler output path is changed for the modules
3. Resources settings are ignored totally and only taken from pom.xml
4. Module dependencies are messed up and have to checked
5. Language/Encoding settings are changed for the modules

All these points need review and adjusting but after this it works like charm.

Further more unfortunately there is no sufficient pom.xml template created, I have added an example which might help to solve most problems.

Edit 2019:

• Added recursive resource scan
• Added directory specification which might be important to avoid confusion of IDEA recarding the content root structure

Another poster provided a lookup-table using a byte-wide lookup. In case you want to eke out a bit more performance (at the cost of 32K of memory instead of just 256 lookup entries) here is a solution using a 15-bit lookup table, in C# 7 for .NET.

The interesting part is initializing the table. Since it's a relatively small block that we want for the lifetime of the process, I allocate unmanaged memory for this by using Marshal.AllocHGlobal. As you can see, for maximum performance, the whole example is written as native:

readonly static byte[] msb_tab_15;

// Initialize a table of 32768 bytes with the bit position (counting from LSB=0)
// of the highest 'set' (non-zero) bit of its corresponding 16-bit index value.
// The table is compressed by half, so use (value >> 1) for indexing.
static MyStaticInit()
{
    var p = new byte[0x8000];

    for (byte n = 0; n < 16; n++)
        for (int c = (1 << n) >> 1, i = 0; i < c; i++)
            p[c + i] = n;

    msb_tab_15 = p;
}

The table requires one-time initialization via the code above. It is read-only so a single global copy can be shared for concurrent access. With this table you can quickly look up the integer log₂, which is what we're looking for here, for all the various integer widths (8, 16, 32, and 64 bits).

Notice that the table entry for 0, the sole integer for which the notion of 'highest set bit' is undefined, is given the value -1. This distinction is necessary for proper handling of 0-valued upper words in the code below. Without further ado, here is the code for each of the various integer primitives:

ulong (64-bit) Version

/// <summary> Index of the highest set bit in 'v', or -1 for value '0' </summary>
public static int HighestOne(this ulong v)
{
    if ((long)v <= 0)
        return (int)((v >> 57) & 0x40) - 1;      // handles cases v==0 and MSB==63

    int j = /**/ (int)((0xFFFFFFFFU - v /****/) >> 58) & 0x20;
    j |= /*****/ (int)((0x0000FFFFU - (v >> j)) >> 59) & 0x10;
    return j + msb_tab_15[v >> (j + 1)];
}

uint (32-bit) Version

/// <summary> Index of the highest set bit in 'v', or -1 for value '0' </summary>
public static int HighestOne(uint v)
{
    if ((int)v <= 0)
        return (int)((v >> 26) & 0x20) - 1;     // handles cases v==0 and MSB==31

    int j = (int)((0x0000FFFFU - v) >> 27) & 0x10;
    return j + msb_tab_15[v >> (j + 1)];
}

Various overloads for the above

public static int HighestOne(long v) => HighestOne((ulong)v);
public static int HighestOne(int v) => HighestOne((uint)v);
public static int HighestOne(ushort v) => msb_tab_15[v >> 1];
public static int HighestOne(short v) => msb_tab_15[(ushort)v >> 1];
public static int HighestOne(char ch) => msb_tab_15[ch >> 1];
public static int HighestOne(sbyte v) => msb_tab_15[(byte)v >> 1];
public static int HighestOne(byte v) => msb_tab_15[v >> 1];

This is a complete, working solution which represents the best performance on .NET 4.7.2 for numerous alternatives that I compared with a specialized performance test harness. Some of these are mentioned below. The test parameters were a uniform density of all 65 bit positions, i.e., 0 ... 31/63 plus value 0 (which produces result -1). The bits below the target index position were filled randomly. The tests were x64 only, release mode, with JIT-optimizations enabled.

That's the end of my formal answer here; what follows are some casual notes and links to source code for alternative test candidates associated with the testing I ran to validate the performance and correctness of the above code.

The version provided above above, coded as Tab16A was a consistent winner over many runs. These various candidates, in active working/scratch form, can be found here, here, and here.

Notable is that the terrible performance of ntdll.dll!RtlFindMostSignificantBit via P/Invoke:

[DllImport("ntdll.dll"), SuppressUnmanagedCodeSecurity, SecuritySafeCritical]
public static extern int RtlFindMostSignificantBit(ulong ul);

It's really too bad, because here's the entire actual function:

    RtlFindMostSignificantBit:
        bsr rdx, rcx  
        mov eax,0FFFFFFFFh  
        movzx ecx, dl  
        cmovne      eax,ecx  
        ret

I can't imagine the poor performance originating with these five lines, so the managed/native transition penalties must be to blame. I was also surprised that the testing really favored the 32KB (and 64KB) short (16-bit) direct-lookup tables over the 128-byte (and 256-byte) byte (8-bit) lookup tables. I thought the following would be more competitive with the 16-bit lookups, but the latter consistently outperformed this:

public static int HighestOne_Tab8A(ulong v)
{
    if ((long)v <= 0)
        return (int)((v >> 57) & 64) - 1;

    int j;
    j =  /**/ (int)((0xFFFFFFFFU - v) >> 58) & 32;
    j += /**/ (int)((0x0000FFFFU - (v >> j)) >> 59) & 16;
    j += /**/ (int)((0x000000FFU - (v >> j)) >> 60) & 8;
    return j + msb_tab_8[v >> j];
}

The last thing I'll point out is that I was quite shocked that my deBruijn method didn't fare better. This is the method that I had previously been using pervasively:

const ulong N_bsf64 = 0x07EDD5E59A4E28C2,
            N_bsr64 = 0x03F79D71B4CB0A89;

readonly public static sbyte[]
bsf64 =
{
    63,  0, 58,  1, 59, 47, 53,  2, 60, 39, 48, 27, 54, 33, 42,  3,
    61, 51, 37, 40, 49, 18, 28, 20, 55, 30, 34, 11, 43, 14, 22,  4,
    62, 57, 46, 52, 38, 26, 32, 41, 50, 36, 17, 19, 29, 10, 13, 21,
    56, 45, 25, 31, 35, 16,  9, 12, 44, 24, 15,  8, 23,  7,  6,  5,
},
bsr64 =
{
     0, 47,  1, 56, 48, 27,  2, 60, 57, 49, 41, 37, 28, 16,  3, 61,
    54, 58, 35, 52, 50, 42, 21, 44, 38, 32, 29, 23, 17, 11,  4, 62,
    46, 55, 26, 59, 40, 36, 15, 53, 34, 51, 20, 43, 31, 22, 10, 45,
    25, 39, 14, 33, 19, 30,  9, 24, 13, 18,  8, 12,  7,  6,  5, 63,
};

public static int IndexOfLSB(ulong v) =>
    v != 0 ? bsf64[((v & (ulong)-(long)v) * N_bsf64) >> 58] : -1;

public static int IndexOfMSB(ulong v)
{
    if ((long)v <= 0)
        return (int)((v >> 57) & 64) - 1;

    v |= v >> 1; v |= v >> 2;  v |= v >> 4;   // does anybody know a better
    v |= v >> 8; v |= v >> 16; v |= v >> 32;  // way than these 12 ops?
    return bsr64[(v * N_bsr64) >> 58];
}

There's much discussion of how superior and great deBruijn methods at this SO question, and I had tended to agree. My speculation is that, while both the deBruijn and direct lookup table methods (that I found to be fastest) both have to do a table lookup, and both have very minimal branching, only the deBruijn has a 64-bit multiply operation. I only tested the IndexOfMSB functions here--not the deBruijn IndexOfLSB--but I expect the latter to fare much better chance since it has so many fewer operations (see above), and I'll likely continue to use it for LSB.

It's very simple to control custom messages with the help of HTML5 event oninvalid

Here is code:

<input id="UserID"  type="text" required="required"
       oninvalid="this.setCustomValidity('Witinnovation')"
       onvalid="this.setCustomValidity('')">

This is most important:

onvalid="this.setCustomValidity('')"

You get this error when you try to run a 32-bit build on your 64-bit Linux.

Also contrast what file had to say on the binary you tried (ie: 32-bit) with what you get for your /bin/gzip:

$ file /bin/gzip
/bin/gzip: ELF 64-bit LSB executable, x64-64, version 1 (SYSV), \
dynamically linked (uses shared libs), for GNU/Linux 2.6.15, stripped

which is what I get on Ubuntu 9.10 for amd64 aka x86_64.

Edit: Your expanded post shows that as the readelf output also reflects a 32-bit build.

One liner answer to the above question is :-

let the two lists be list1 and list2, and your requirement is to ensure whether two lists have the same elements, then as per me, following will be the best approach :-

if ((len(list1) == len(list2)) and
   (all(i in list2 for i in list1))):
    print 'True'
else:
    print 'False'

The above piece of code will work per your need i.e. whether all the elements of list1 are in list2 and vice-verse.

But if you want to just check whether all elements of list1 are present in list2 or not, then you need to use the below code piece only :-

if all(i in list2 for i in list1):
    print 'True'
else:
    print 'False'

The difference is, the later will print True, if list2 contains some extra elements along with all the elements of list1. In simple words, it will ensure that all the elements of list1 should be present in list2, regardless of whether list2 has some extra elements or not.

Get Shared Preferences Color Code in String then Convert to integer and add layout-background color:

    sharedPreferences = getSharedPreferences(mypref, Context.MODE_PRIVATE);
    String sw=sharedPreferences.getString(name, "");
    relativeLayout.setBackgroundColor(Color.parseColor(sw));

There are actually two place where where mac os x serves website by default:

/Library/WebServer/Documents --> http://localhost

~/Sites --> http://localhost/~user/

.toString() is available, or just add "" to the end of the int

var x = 3,
    toString = x.toString(),
    toConcat = x + "";

Angular is simply JavaScript at the core.

When you really want to write an i-test for a spring data repository you can do it like this:

@RunWith(SpringRunner.class)
@DataJpaTest
@EnableJpaRepositories(basePackageClasses = WebBookingRepository.class)
@EntityScan(basePackageClasses = WebBooking.class)
public class WebBookingRepositoryIntegrationTest {

    @Autowired
    private WebBookingRepository repository;

    @Test
    public void testSaveAndFindAll() {
        WebBooking webBooking = new WebBooking();
        webBooking.setUuid("some uuid");
        webBooking.setItems(Arrays.asList(new WebBookingItem()));
        repository.save(webBooking);

        Iterable<WebBooking> findAll = repository.findAll();

        assertThat(findAll).hasSize(1);
        webBooking.setId(1L);
        assertThat(findAll).containsOnly(webBooking);
    }
}

To follow this example you have to use these dependencies:

My solution works with MySQL date time formats and provides a callback function. on complition. Disclaimer: works only with minutes and seconds, as this is what I needed.

jQuery.fn.countDownTimer = function(futureDate, callback){
    if(!futureDate){
        throw 'Invalid date!';
    }

    var currentTs = +new Date();
    var futureDateTs = +new Date(futureDate);

    if(futureDateTs <= currentTs){
        throw 'Invalid date!';
    }


    var diff = Math.round((futureDateTs - currentTs) / 1000);
    var that = this;

    (function countdownLoop(){
        // Get hours/minutes from timestamp
        var m = Math.floor(diff % 3600 / 60);
        var s = Math.floor(diff % 3600 % 60);
        var text = zeroPad(m, 2) + ':' + zeroPad(s, 2);

        $(that).text(text);

        if(diff <= 0){
            typeof callback === 'function' ? callback.call(that) : void(0);
            return;
        }

        diff--;
        setTimeout(countdownLoop, 1000);
    })();

    function zeroPad(num, places) {
      var zero = places - num.toString().length + 1;
      return Array(+(zero > 0 && zero)).join("0") + num;
    }
}

// $('.heading').countDownTimer('2018-04-02 16:00:59', function(){ // on complete})

    define('ENVIRONMENT', 'development');
} else {
    define('ENVIRONMENT', 'production');
}

if (defined('ENVIRONMENT')){
    switch (ENVIRONMENT){
        case 'development':
            error_reporting(E_ALL);
        break;

        case 'testing':
        case 'production':
            error_reporting(0);
        break;

        default:
            exit('The application environment is not set correctly.');
    }
}

IF PHP errors are off, but any MySQL errors are still going to show, turn these off in the /config/database.php file. Set the db_debug option to false:

$db['default']['db_debug'] = FALSE; 

Also, you can use active_group as development and production to match the environment https://www.codeigniter.com/user_guide/database/configuration.html

$active_group = 'development';


$db['development']['hostname'] = 'localhost';
$db['development']['username'] = '---';
$db['development']['password'] = '---';
$db['development']['database'] = '---';
$db['development']['dbdriver'] = 'mysql';
$db['development']['dbprefix'] = '';
$db['development']['pconnect'] = TRUE;

$db['development']['db_debug'] = TRUE;

$db['development']['cache_on'] = FALSE;
$db['development']['cachedir'] = '';
$db['development']['char_set'] = 'utf8';
$db['development']['dbcollat'] = 'utf8_general_ci';
$db['development']['swap_pre'] = '';
$db['development']['autoinit'] = TRUE;
$db['development']['stricton'] = FALSE;



$db['production']['hostname'] = 'localhost';
$db['production']['username'] = '---';
$db['production']['password'] = '---';
$db['production']['database'] = '---';
$db['production']['dbdriver'] = 'mysql';
$db['production']['dbprefix'] = '';
$db['production']['pconnect'] = TRUE;

$db['production']['db_debug'] = FALSE;

$db['production']['cache_on'] = FALSE;
$db['production']['cachedir'] = '';
$db['production']['char_set'] = 'utf8';
$db['production']['dbcollat'] = 'utf8_general_ci';
$db['production']['swap_pre'] = '';
$db['production']['autoinit'] = TRUE;
$db['production']['stricton'] = FALSE;

If you want to search for the last instance of a string in a text, you can run rfind.

Example:

   s="Hello"
   print s.rfind('l')

output: 3

*no import needed

Complete syntax:

stringEx.rfind(substr, beg=0, end=len(stringEx))

I know nothing about Jenkins, but it looks like you are trying to access environment variables using some form of unix syntax - that won't work.

If the name of the variable is WORKSPACE, then the value is expanded in Windows batch using
%WORKSPACE%. That form of expansion is performed at parse time. For example, this will print to screen the value of WORKSPACE

echo %WORKSPACE%

If you need the value at execution time, then you need to use delayed expansion !WORKSPACE!. Delayed expansion is not normally enabled by default. Use SETLOCAL EnableDelayedExpansion to enable it. Delayed expansion is often needed because blocks of code within parentheses and/or multiple commands concatenated by &, &&, or || are parsed all at once, so a value assigned within the block cannot be read later within the same block unless you use delayed expansion.

setlocal enableDelayedExpansion
set WORKSPACE=BEFORE
(
  set WORKSPACE=AFTER
  echo Normal Expansion = %WORKSPACE%
  echo Delayed Expansion = !WORKSPACE!
)

The output of the above is

Normal Expansion = BEFORE
Delayed Expansion = AFTER

Use HELP SET or SET /? from the command line to get more information about Windows environment variables and the various expansion options. For example, it explains how to do search/replace and substring operations.

Remove a determinated string from start and end from a string.

s = '""Hello World""'
s.strip('""')

> 'Hello World'

Those of us using Python 3.x should do this:

python -c "import sys; print(sys.path)"

Quick Update, effective from February 15th, 2015, we cannot submit apps to the store that were developed using an SDK prior to iOS 8. So, keeping that in mind , its better to not to worry about this issue as many people have suggested that apps made in Swift can be deployed to OS X 10.9 and iOS 7.0 as well.

I come to this question quite regularly and it always takes me a while to find what I search:

Add Class

• Cross Compatible

  In the following example we add a classname to the <body> element. This is IE-8 compatible.

  var a = document.body;
  a.classList ? a.classList.add('classname') : a.className += ' classname';
  

  This is shorthand for the following..

  var a = document.body;
  if (a.classList) {
      a.classList.add('wait');
  } else {
      a.className += ' wait';
  }
  

• Performance

  If your more concerned with performance over cross-compatibility you can shorten it to the following which is 4% faster.

  var z = document.body;
  document.body.classList.add('wait');
  

• Convenience

  Alternatively you could use jQuery but the resulting performance is significantly slower. 94% slower according to jsPerf

  $('body').addClass('wait');
  

Removing the class

• Performance

  Using jQuery selectively is the best method for removing a class if your concerned with performance

  var a = document.body, c = ' classname';
  $(a).removeClass(c);
  

• Without jQuery it's 32% slower

  var a = document.body, c = ' classname';
  a.className = a.className.replace( c, '' );
  a.className = a.className + c;

There are two solutions posted on that page. The one with lower votes I would recommend if possible.

If you are using HTML5 then it is perfectly valid to put a div inside of a. As long as the div doesn't also contain some other specific elements like other link tags.

<a href="Music.html">
  <div id="music" class="nav">
    Music I Like
  </div>
</a>

The solution you are confused about actually makes the link as big as its container div. To make it work in your example you just need to add position: relative to your div. You also have a small syntax error which is that you have given the span a class instead of an id. You also need to put your span inside the link because that is what the user is clicking on. I don't think you need the z-index at all from that example.

div { position: relative; }
.hyperspan {
    position:absolute;
    width:100%;
    height:100%;
    left:0;
    top:0;
}

<div id="music" class="nav">Music I Like 
    <a href="http://www.google.com"> 
        <span class="hyperspan"></span>
    </a>   
</div>

http://jsfiddle.net/rBKXM/9

When you give absolute positioning to an element it bases its location and size after the first parent it finds that is relatively positioned. If none, then it uses the document. By adding relative to the parent div you tell the span to only be as big as that.

For this particular case, if using re module is overkill, how about using split (or rsplit) method as

se='</html>'
z.write(article.split(se)[0]+se)

For example,

#!/usr/bin/python

article='''<html>Larala
Ponta Monta 
</html>Kurimon
Waff Moff
'''
z=open('out.txt','w')

se='</html>'
z.write(article.split(se)[0]+se)

outputs out.txt as

<html>Larala
Ponta Monta 
</html>

Maybe too late, but I'd cast 0/1 as bit to make the datatype eventually becomes True/False when consumed by .NET framework:

SELECT   EntityId, 
         EntityName, 
         CASE 
            WHEN EntityProfileIs IS NULL 
            THEN CAST(0 as bit) 
            ELSE CAST(1 as bit) END AS HasProfile
FROM      Entities
LEFT JOIN EntityProfiles ON EntityProfiles.EntityId = Entities.EntityId`

Don't know why but in my case it doesn't work the way suggested earlier. But it works like this:

Time.now.change(offset: "-3000")

Of course you need to change offset value to yours.

currentDate(){
        var today = new Date();
        var dateTime =  today.getFullYear()+'-'+
                        ((today.getMonth()+1)<10?("0"+(today.getMonth()+1)):(today.getMonth()+1))+'-'+
                        (today.getDate()<10?("0"+today.getDate()):today.getDate())+'T'+
                        (today.getHours()<10?("0"+today.getHours()):today.getHours())+ ":" +
                        (today.getMinutes()<10?("0"+today.getMinutes()):today.getMinutes())+ ":" +
                        (today.getSeconds()<10?("0"+today.getSeconds()):today.getSeconds());        
            return dateTime;
},

There are two problems in your code:

• The property is called visibility and not visiblity.
• It is not a property of the element itself but of its .style property.

It's easy to fix. Simple replace this:

document.getElementById("remember").visiblity

with this:

document.getElementById("remember").style.visibility

Why not simply return your calculated value and let the caller modify the global variable. It's not a good idea to manipulate a global variable within a function, as below:

Var1 = 1
Var2 = 0

def function(): 
    if Var2 == 0 and Var1 > 0:
        print("Result One")
    elif Var2 == 1 and Var1 > 0:
        print("Result Two")
    elif Var1 < 1:
        print("Result Three")
    return Var1 - 1

Var1 = function()

or even make local copies of the global variables and work with them and return the results which the caller can then assign appropriately

def function():
v1, v2 = Var1, Var2
# calculate using the local variables v1 & v2
return v1 - 1

Var1 = function()

Probably working Perl solution, if the string is on one line:

my $NesteD ;
$NesteD = qr/ \{( [^{}] | (??{ $NesteD }) )* \} /x ;

if ( $Stringy =~ m/\b( \w+$NesteD )/x ) {
    print "Found: $1\n" ;
  }

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

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

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

define the indices in a header file:-

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

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

Using a macro, also in the header file:-

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

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

const char * FruitString(enum fruit e){

    unsigned int index;

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

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

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

string EnumToString(fruit e);

)

public static <T> List<T> toList(String json, Class<T> clazz) {
    if (null == json) {
        return null;
    }
    Gson gson = new Gson();
    return gson.fromJson(json, new TypeToken<T>(){}.getType());
}

sample call:

List<Specifications> objects = GsonUtils.toList(products, Specifications.class);

QMessageBox includes static methods to quickly ask such questions:

#include <QApplication>
#include <QMessageBox>

int main(int argc, char **argv)
{
    QApplication app{argc, argv};
    while (QMessageBox::question(nullptr,
                                 qApp->translate("my_app", "Test"),
                                 qApp->translate("my_app", "Are you sure you want to quit?"),
                                 QMessageBox::Yes|QMessageBox::No)
           != QMessageBox::Yes)
        // ask again
        ;
}

If your needs are more complex than provided for by the static methods, you should construct a new QMessageBox object, and call its exec() method to show it in its own event loop and obtain the pressed button identifier. For example, we might want to make "No" be the default answer:

#include <QApplication>
#include <QMessageBox>

int main(int argc, char **argv)
{
    QApplication app{argc, argv};
    auto question = new QMessageBox(QMessageBox::Question,
                                    qApp->translate("my_app", "Test"),
                                    qApp->translate("my_app", "Are you sure you want to quit?"),
                                    QMessageBox::Yes|QMessageBox::No,
                                    nullptr);
    question->setDefaultButton(QMessageBox::No);

    while (question->exec() != QMessageBox::Yes)
        // ask again
        ;
}

I had faced the similar issue while using Convert.ToSingle(my_value) If the OS language settings is English 2.5 (example) will be taken as 2.5 If the OS language is German, 2.5 will be treated as 2,5 which is 25 I used the invariantculture IFormat provided and it works. It always treats '.' as '.' instead of ',' irrespective of the system language.

float var = Convert.ToSingle(my_value, System.Globalization.CultureInfo.InvariantCulture);

Programmatically it can be done by :

image_button.setAlpha(0f) // to make it full transparent
image_button.setAlpha(0.5f) // to make it half transparent
image_button.setAlpha(0.6f) // to make it (40%) transparent
image_button.setAlpha(1f) // to make it opaque

                break;
            }
        }
        columnIndex++; // keep adding 1 while we don't have the correct name
    }
    return foundIndex;
}

and

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        int index = GetColumnIndexByName(e.Row, "myDataField");
        if( index>0)
        {
            string columnValue = e.Row.Cells[index].Text;
        }
    }
}

It would probably be easier to just fake it by using a div. Just make sure you set the height if its empty so that it can actually appear. Say for instance you want it to be 50px tall set the div height to 50px.

<div id="rightflower">
<div id="divImg"></div> 
</div>

And in your style sheet just add the background and its properties, height and width, and what ever positioning you had in mind.

You need to change the sshd_config file in the remote server (probably in /etc/ssh/sshd_config).

Change

PasswordAuthentication no

to

PasswordAuthentication yes

And then restart the sshd daemon.

The following code changes the hexadecimal string to a byte array by parsing the string byte-by-byte.

public static byte[] ConvertHexStringToByteArray(string hexString)
{
    if (hexString.Length % 2 != 0)
    {
        throw new ArgumentException(String.Format(CultureInfo.InvariantCulture, "The binary key cannot have an odd number of digits: {0}", hexString));
    }

    byte[] data = new byte[hexString.Length / 2];
    for (int index = 0; index < data.Length; index++)
    {
        string byteValue = hexString.Substring(index * 2, 2);
        data[index] = byte.Parse(byteValue, NumberStyles.HexNumber, CultureInfo.InvariantCulture);
    }

    return data; 
}

Just did this and UrlSearchParams did the trick Here is my code if it helps someone

import 'url-search-params-polyfill';
const userLogsInOptions = (username, password) => {



// const formData = new FormData();
  const formData = new URLSearchParams();
  formData.append('grant_type', 'password');
  formData.append('client_id', 'entrance-app');
  formData.append('username', username);
  formData.append('password', password);
  return (
    {
      method: 'POST',
      headers: {
        // "Content-Type": "application/json; charset=utf-8",
        "Content-Type": "application/x-www-form-urlencoded",
    },
      body: formData.toString(),
    json: true,
  }
  );
};


const getUserUnlockToken = async (username, password) => {
  const userLoginUri = `${scheme}://${host}/auth/realms/${realm}/protocol/openid-connect/token`;
  const response = await fetch(
    userLoginUri,
    userLogsInOptions(username, password),
  );
  const responseJson = await response.json();
  console.log('acces_token ', responseJson.access_token);
  if (responseJson.error) {
    console.error('error ', responseJson.error);
  }
  console.log('json ', responseJson);
  return responseJson.access_token;
};

Most of the answers are disabling animations or creating new copies of data which is an overkill in my opinion. They do work but they don't address the root cause of the issue. In my case it was due to using DiffUtils in a wrong way. In the areItemsTheSame(old, new) method I did not properly implement the equality check, that, in turn cased the adapter to be notified by notifyItemRangeInserted() even though the same number of items are in the new list. So pay close attention to how you implement the DiffUtils callbacks!

Did you edit the AndroidManifest.xml directly in the .apk file? If so, that won't work.

Every Android .apk needs to be signed if it is going to be installed on a phone, even if you're not installing through the Market. The development tools work round this by signing with a development certificate but the .apk is still signed.

One use of this is so a device can tell if an .apk is a valid upgrade for an installed application, since if it is the Certificates will be the same.

So if you make any changes to your app at all you'll need to rebuild the .apk so it gets signed properly.

On a 64-bit system you have to make sure that both the Tomcat application and the JDK are the same architecture: either both are x86 or x64.

In case you want to change the Tomcat instance to x64 you might have to download the tomcat8.exe or tomcat9.exe and the tcnative-1.dll with the appropriate x64 versions. You can get those at http://svn.apache.org/viewvc/tomcat/.

Alternatively you can point Tomcat to the x86 JDK by changing the Java Virtual Machine path in the Tomcat config.

For practically all date and time matters I prefer to simplify things, very, very simple... Down to seconds stored in integers.

Integers will always be supported as integers in databases, flat files, etc. You do a little math and cast it into another type and you can format the date anyway you want.

Doing it this way, you don't have to worry when [insert current favorite database here] is replaced with [future favorite database] which coincidentally didn't use the date format you chose today.

It's just a little math overhead (eg. methods--takes two seconds, I'll post a gist if necessary) and simplifies things for a lot of operations regarding date/time later.

You can use calc (100% - 100px) on the fluid element, along with display:inline-block for both elements.

Be aware that there should not be any space between the tags, otherwise you will have to consider that space in your calc too.

.left{
    display:inline-block;
    width:100px;
}
.right{
    display:inline-block;
    width:calc(100% - 100px);
}


<div class=“left”></div><div class=“right”></div>

Quick example: http://jsfiddle.net/dw689mt4/1/

Try this link.... horizontal rule

That should do the trick.

The code below is xml.

<View
    android:layout_width="fill_parent"
    android:layout_height="2dip"
    android:background="#FF00FF00" />

As per this link you may also have to prefix your param with &rp if not using proxy syntax

You can find/debug XPath/CSS locators in the IE as well as in different browsers with the tool called SWD Page Recorder

The only restrictions/limitations:

1. The browser should be started from the tool
2. Internet Explorer Driver Server - IEDriverServer.exe - should be downloaded separately and placed near SwdPageRecorder.exe

If using STS, you can in Eclipse mark the configuration file as "Bean Configuration" file (you can specify that when creating or on right click on a XML file):

You project has to have Spring Nature (right click on maven project for example):

then spring.xml is opened by default with Spring Config Editor

and this editor has Namespaces tab

Which enables you to specify the namespaces:

Please be aware, that it depends on dependencies (using maven project), so if spring-tx is not defined in maven's pom.xml, option is not there, which prevents you to have The matching wildcard is strict, but no declaration can be found for element 'tx:annotation-driven' 'context:component-scan' problem...

You can use the mounted() Vue Lifecycle Hook. This will allow you to call a method before the page loads.

This is an implementation example:

HTML:

<div id="app">
  <h1>Welcome our site {{ name }}</h1>
</div>

JS:

var app = new Vue ({
    el: '#app',
    data: {
        name: ''
    },
    mounted: function() {
        this.askName() // Calls the method before page loads
    },
    methods: {
        // Declares the method
        askName: function(){
            this.name = prompt(`What's your name?`)
        }
    }
})

This will get the prompt method's value, insert it in the variable name and output in the DOM after the page loads. You can check the code sample here.

You can read more about Lifecycle Hooks here.

To use $variables inside your calc() of the height property:

HTML:

<div></div>

SCSS:

$a: 4em;

div {
  height: calc(#{$a} + 7px);
  background: #e53b2c;
}

The instruction has been tested on Mac OSx Catalina.

After installing Sublime Text 3, install Package Control through Tools > Package Control. Use the following instructions to install package or theme:

1. press CMD + SHIFT + P

2. choose Package Control: Install Package---or any other options you require.

3. enter the name of required package or theme and press enter.

I wouldn't recommended this is you've got a lot of "thinking" in your app, but using XSLT could be better (and potentially faster with XSLT-to-bytecode compilation) than Java manipulation.

2014 and above at least you can set a default and it will take that and NOT error when you do not pass that parameter. Partial Example: the 3rd parameter is added as optional. exec of the actual procedure with only the first two parameters worked fine

exec getlist 47,1,0

create procedure getlist
   @convId int,
   @SortOrder int,
   @contestantsOnly bit = 0
as

PRIMARY KEY CONSTRAINT cannot be altered, you may only drop it and create again. For big datasets it can cause a long run time and thus - table inavailability.

I derived this from all the above answers. Nothing worked for me when I tried each one of them. I did lot of trail and error by combining all the above answers and concluded on this. I am not sure if this works for you but it worked for me on Ununtu 12.04 and RHEL 5.4.

echo "This is the body of the mail" | mail -s 'This is the subject' '<[email protected]>,<[email protected]>' -- -F '<SenderName>' -f '<[email protected]>'

One can send the mail to any number of people by adding any number of receiver id's and the mail is sent by SenderName from [email protected]

Hope this helps.

In your giant elif chain, you skipped 13. You might want to throw an error if you hit the end of the chain without returning anything, to catch numbers you missed and incorrect calls of the function:

else:
    raise ValueError(x)

Run Python Files in Sublime Text3

For Sublime Text 3, First Install Package Control:

• Press Ctrl + Shift + P, a search bar will open

• Type Install package and then press enter Click here to see Install Package Search Pic

• After the package got installed. It may prompt to restart SublimeText

• After completing the above step
• Just again repeat the 1st and 2nd step, it will open the repositories this time
• Search for Python 3 and Hit enter.
• There you go.
• Just press Ctrl + B in your python file and you'll get the output. Click here to see Python 3 repo pic

It perfectly worked for me. Hopefully, it helped you too. For any left requirements, visit https://packagecontrol.io/installation#st3 here.

You cannot change the order of columns in smaller screens but you can do that in large screens.

So change the order of your columns.

<!--Main Content-->
<div class="col-lg-9 col-lg-push-3">
</div>

<!--Sidebar-->
<div class="col-lg-3 col-lg-pull-9">
</div>

By default this displays the main content first.

So in mobile main content is displayed first.

By using col-lg-push and col-lg-pull we can reorder the columns in large screens and display sidebar on the left and main content on the right.

Working fiddle here.

Config file:

}

worker_rlimit_nofile    20000;  # Each connection needs a filehandle (or 2 if you are proxying)


# Total amount of users you can serve = worker_processes * worker_connections

Simply quote your variable:

[ -e "$VAR" ]

This evaluates to [ -e "" ] if $VAR is empty.

Your version does not work because it evaluates to [ -e ]. Now in this case, bash simply checks if the single argument (-e) is a non-empty string.

From the manpage:

test and [ evaluate conditional expressions using a set of rules based on the number of arguments. ...

1 argument

The expression is true if and only if the argument is not null.

(Also, this solution has the additional benefit of working with filenames containing spaces)

I was initially running:

sudo scp

Once I ran just scp, without sudo, it copied everything fine:

scp

It seems to me that sudo scp command wasn't reading my current user's SSH public key at ~/.ssh/id_rsa.pub.

If you have more numbers or if you intend to add new test numbers for CASE then you can use a more flexible approach:

DECLARE @Numbers TABLE
(
    Number VARCHAR(50) PRIMARY KEY
    ,Class TINYINT NOT NULL
);
INSERT @Numbers
VALUES ('1121231',1);
INSERT @Numbers
VALUES ('31242323',1);
INSERT @Numbers
VALUES ('234523',2);
INSERT @Numbers
VALUES ('2342423',2);

SELECT c.*, n.Class
FROM   tblClient c  
LEFT OUTER JOIN   @Numbers n ON c.Number = n.Number;

Also, instead of table variable you can use a regular table.

When we apply local url, ErrorDocument directive expect the full path from DocumentRoot. There fore,

Just delete the whole directory. This will delete all the projects but also the Eclipse cache and settings for the workspace. These are kept in the .metadata folder of an Eclipse workspace. Note that you can configure Eclipse to use project folders that are outside the workspace folder as well, so you may want to verify the location of each of the projects.

You can remove the workspace from the suggested workspaces by going into the General/Startup and Shutdown/Workspaces section of the preferences (via Preferences > General > Startup & Shudown > Workspaces > [Remove] ). Note that this does not remove the files itself. For old versions of Eclipse you will need to edit the org.eclipse.ui.ide.prefs file in the configuration/.settings directory under your installation directory (or in ~/.eclipse on Unix, IIRC).

I too had this problem after updating to the latest Xcode Beta. The settings on the simulator are refreshed, so the laptop (external) keyboard was being detected. If you simply press:

iOS Simulator -> Hardware -> Keyboard -> Connect Hardware Keyboard

so that the entry is UNchecked then the software keyboard will be displayed once again.

These examples seem a bit inefficient. Try this if you want to act upon the value:

<input id="cta" type="email" placeholder="Enter Email...">
<button onclick="return joinMailingList()">Join</button>

<script>
    const joinMailingList = () => {
        const email = document.querySelector('#cta').value
        console.log(email)
    }
</script>

You will encounter issue if you use this keyword with fat arrow (=>). If you need to do that, go old school:

<script>
    function joinMailingList() {
        const email = document.querySelector('#cta').value
        console.log(email)
    }
</script>

If you are working with password inputs, you should use type="password" so it will display ****** while the user is typing, and it is also more semantic.

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

LINQ provides Last():

csharp> int[] nums = {1,2,3,4,5};
csharp> nums.Last();              
5

This is handy when you don't want to make a variable unnecessarily.

string lastName = "Abraham Lincoln".Split().Last();

Dim dgv As DataGridView = Me.TblCalendarDataGridView

For i As Integer = 0 To dgv.Rows.Count - 1
    For ColNo As Integer = 4 To 7
        If Not dgv.Rows(i).Cells(ColNo).Value Is DBNull.Value Then

            dgv.Rows(i).Cells(ColNo).Style.BackColor =  vbcolor.blue
        End If
    Next
Next

For those of you who faced this issue while creating a controller through the context menu, reopening Visual Studio as an administrator fixed it.

You can wire up your own custom event

$('textarea').bind("enterKey",function(e){
   //do stuff here
});
$('textarea').keyup(function(e){
    if(e.keyCode == 13)
    {
        $(this).trigger("enterKey");
    }
});

It can convert by

Convert.ToInt32 method

But it will throw an OverflowException if it the value is outside range of the Int32 Type. A basic test will show us how it works:

long[] numbers = { Int64.MinValue, -1, 0, 121, 340, Int64.MaxValue };
int result;
foreach (long number in numbers)
{
   try {
         result = Convert.ToInt32(number);
        Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                    number.GetType().Name, number,
                    result.GetType().Name, result);
     }
     catch (OverflowException) {
      Console.WriteLine("The {0} value {1} is outside the range of the Int32 type.",
                    number.GetType().Name, number);
     }
}
// The example displays the following output:
//    The Int64 value -9223372036854775808 is outside the range of the Int32 type.
//    Converted the Int64 value -1 to the Int32 value -1.
//    Converted the Int64 value 0 to the Int32 value 0.
//    Converted the Int64 value 121 to the Int32 value 121.
//    Converted the Int64 value 340 to the Int32 value 340.
//    The Int64 value 9223372036854775807 is outside the range of the Int32 type.

Here there is a longer explanation.

This behaviour is now part of the component lifecycle.

A component can implement the ngOnChanges method in the OnChanges interface to get access to input changes.

Example:

import {Component, Input, OnChanges} from 'angular2/core';


@Component({
  selector: 'hero-comp',
  templateUrl: 'app/components/hero-comp/hero-comp.html',
  styleUrls: ['app/components/hero-comp/hero-comp.css'],
  providers: [],
  directives: [],

  pipes: [],
  inputs:['hero', 'real']
})
export class HeroComp implements OnChanges{
  @Input() hero:Hero;
  @Input() real:string;
  constructor() {
  }
  ngOnChanges(changes) {
      console.log(changes);
  }
}

In Asp.net Core 3+ Vesrion

Controller: If wants to return anything related to IActionResult & Data also, go for Controllercontroller

ApiController: Used as attribute/notation in API controller. That inherits ControllerBase Class

ControllerBase: If wants to return data only go for ControllerBase class

Each class will use its own classloader to load other classes. So if ClassA.class references ClassB.class then ClassB needs to be on the classpath of the classloader of ClassA, or its parents.

The thread context classloader is the current classloader for the current thread. An object can be created from a class in ClassLoaderC and then passed to a thread owned by ClassLoaderD. In this case the object needs to use Thread.currentThread().getContextClassLoader() directly if it wants to load resources that are not available on its own classloader.

Same as the answer from 'Richie' but a bit more concise.

1. Query for user constraints only

   SELECT column_name FROM all_cons_columns WHERE constraint_name = (
     SELECT constraint_name FROM user_constraints 
     WHERE UPPER(table_name) = UPPER('tableName') AND CONSTRAINT_TYPE = 'P'
   );
   

2. Query for all constraints

   SELECT column_name FROM all_cons_columns WHERE constraint_name = (
     SELECT constraint_name FROM all_constraints 
     WHERE UPPER(table_name) = UPPER('tableName') AND CONSTRAINT_TYPE = 'P'
   );
   

There is no difference, except that Pragma is only defined as applicable to the requests by the client, whereas Cache-Control may be used by both the requests of the clients and the replies of the servers.

So, as far as standards go, they can only be compared from the perspective of the client making a requests and the server receiving a request from the client. The http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.32 defines the scenario as follows:

HTTP/1.1 caches SHOULD treat "Pragma: no-cache" as if the client had sent "Cache-Control: no-cache". No new Pragma directives will be defined in HTTP.

  Note: because the meaning of "Pragma: no-cache as a response
  header field is not actually specified, it does not provide a
  reliable replacement for "Cache-Control: no-cache" in a response

The way I would read the above:

• if you're writing a client and need no-cache:

  • just use Pragma: no-cache in your requests, since you may not know if Cache-Control is supported by the server;
  • but in replies, to decide on whether to cache, check for Cache-Control

• if you're writing a server:

  • in parsing requests from the clients, check for Cache-Control; if not found, check for Pragma: no-cache, and execute the Cache-Control: no-cache logic;
  • in replies, provide Cache-Control.

Of course, reality might be different from what's written or implied in the RFC!

I get the same error when I run Oracle XE instance on the same machine. As my database is Oracle, I preferred changing Glassfish's default port:

1. Locate domain.xml inside Glassfish installation folders.
2. Change the the port on the below line:

  <network-listener port="9090" protocol="http-listener-1" transport="tcp" name="http-listener-1" thread-pool="http-thread-pool"></network-listener>_x000D_
        

The CLR uses it when it is compiling at runtime. Here is a link to MSDN that explains further.

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
char *substring(int i,int j,char *ch)
{
    int n,k=0;
    char *ch1;
    ch1=(char*)malloc((j-i+1)*1);
    n=j-i+1;

    while(k<n)
    {
        ch1[k]=ch[i];
        i++;k++;
    }

    return (char *)ch1;
}

int main()
{
    int i=0,j=2;
    char s[]="String";
    char *test;

    test=substring(i,j,s);
    printf("%s",test);
    free(test); //free the test 
    return 0;
}

This will compile fine without any warning

1. #include stdlib.h
2. pass test=substring(i,j,s);
3. remove m as it is unused
4. either declare char substring(int i,int j,char *ch) or define it before main

Another good solution is to use outline instead of border. It adds a border without affecting the box model. This works on IE8+, Chrome, Firefox, Opera, Safari.

You can use either length property and length is better on performance than size.

$('#input1 option').length;

OR you can use size function like (removed in jQuery v3)

$('#input1 option').size(); 

$(document).ready(function(){
   console.log($('#input1 option').size());
   console.log($('#input1 option').length);
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<select data-attr="dropdown" id="input1">
   <option value="Male" id="Male">Male</option>
   <option value="Female" id="Female">Female</option>
</select>

It follows the convention that static methods should be thread-safe, but actually in v2 that static api is a proxy to an instance method on a default instance: in the case protobuf-net, it internally minimises contention points, and synchronises the internal state when necessary. Basically the library goes out of its way to do things right so that you can have simple code.

Posting a note here for users looking into this into the future. Google's libphonenumber is what you most likely would want to use. There is wrappers for PHP, node.js, Java, etc. to use the data which Google has been collecting and reduces the requirements for maintaining large arrays of regex patterns to apply.

You can also use kafkactl for this:

# get all consumer groups (output as yaml)
kafkactl get consumer-groups -o yaml

# get only consumer groups assigned to a single topic (output as table)
kafkactl get consumer-groups --topic topic-a

Sample output (e.g. as yaml):

name: my-group
protocoltype: consumer
topics:
 - topic-a
 - topic-b
 - topic-c

git clone --filter=blob:none --no-checkout --single-branch --branch master git://some.repo.git .
git log

This will vary depending on your architecture and how it treats basic data types. It will also depend on whether the system requires natural alignment.

awk '$3 ~ /snow/ { print }' dummy_file 

Not sure about the performance implications, but it seems a possible compromise, at least during development, would be to include both the auto-incremented, integer "surrogate" key, as well as your intended, unique, "natural" key. This would give you the opportunity to evaluate performance, as well as other possible issues, including the changeability of natural keys.

/dev/null is a standard file that discards all you write to it, but reports that the write operation succeeded.

1 is standard output and 2 is standard error.

2>&1 redirects standard error to standard output. &1 indicates file descriptor (standard output), otherwise (if you use just 1) you will redirect standard error to a file named 1. [any command] >>/dev/null 2>&1 redirects all standard error to standard output, and writes all of that to /dev/null.

As Kris mentions, you can use the $resource service to interact with the server, but I get the impression you are beginning your journey with Angular - I was there last week - so I recommend to start experimenting directly with the $http service. In this case you can call its get method.

If you have the following JSON

[{ "text":"learn angular", "done":true },
 { "text":"build an angular app", "done":false},
 { "text":"something", "done":false },
 { "text":"another todo", "done":true }]

You can load it like this

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

App.controller('TodoCtrl', function($scope, $http) {
  $http.get('todos.json')
       .then(function(res){
          $scope.todos = res.data;                
        });
});

The get method returns a promise object which first argument is a success callback and the second an error callback.

When you add $http as a parameter of a function Angular does it magic and injects the $http resource into your controller.

I've put some examples here

Try littler. littler provides hash-bang (i.e. script starting with #!/some/path) capability for GNU R, as well as simple command-line and piping use.

Use getattr to get an attribute from a name in a string. In other words, get the instance as

instance = getattr(modul, class_name)()

you can use a static array in your method, to avoid lose of your array when your function ends :

char * createStr() 
{
    char char1= 'm';
    char char2= 'y';

    static char str[3];  
    str[0] = char1;
    str[1] = char2;
    str[2] = '\0';

    return str;
}

Edit : As Toby Speight mentioned this approach is not thread safe, and also recalling the function leads to data overwrite that is unwanted in some applications. So you have to save the data in a buffer as soon as you return back from the function. (However because it is not thread safe method, concurrent calls could still make problem in some cases, and to prevent this you have to use lock. capture it when entering the function and release it after copy is done, i prefer not to use this approach because its messy and error prone.)

Copy all file and replace to /var/lib/mysql , after that you must change owner of files to mysql this is so important if mariadb.service restart has been faild

chown -R mysql:mysql /var/lib/mysql/*

and

chmod -R 700 /var/lib/mysql/*

One simple solution to the problem -

JAVA_HOME=/usr/lib/jvm/java-6-sun/ mvn clean install

On Mac, it would look something like -

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_21.jdk/Contents/Home/ mvn clean install

PS: One special case that i found is the above given command does not work on 'fish' shell. I also had bash shell available and it worked fine there. just use command 'bash' to switch to bash shell.

Although it is safe to declare a static ObjectMapper in terms of thread safety, you should be aware that constructing static Object variables in Java is considered bad practice. For more details, see Why are static variables considered evil? (and if you'd like, my answer)

In short, statics should be avoided because the make it difficult to write concise unit tests. For example, with a static final ObjectMapper, you can't swap out the JSON serialization for dummy code or a no-op.

In addition, a static final prevents you from ever reconfiguring ObjectMapper at runtime. You might not envision a reason for that now, but if you lock yourself into a static final pattern, nothing short of tearing down the classloader will let you re-initialize it.

In the case of ObjectMapper its fine, but in general it is bad practice and there is no advantage over using a singleton pattern or inversion-of-control to manage your long-lived objects.

Put your code in a method.

Try this:

public class MyClass {
    public static void main(String[] args) {
        UserInput input = new UserInput();
        input.name();
    }
}

Then "run" the class from your IDE

The ideal situation for resolving conflicts is when you know ahead of time which way you want to resolve them and can pass the -Xours or -Xtheirs recursive merge strategy options. Outside of this I can see three scenarious:

1. You want to just keep a single version of the file (this should probably only be used on unmergeable binary files, since otherwise conflicted and non-conflicted files may get out of sync with each other).
2. You want to simply decide all of the conflicts in a particular direction.
3. You need to resolve some conflicts manually and then resolve all of the rest in a particular direction.

To address these three scenarios you can add the following lines to your .gitconfig file (or equivalent):

[merge]
  conflictstyle = diff3
[mergetool.getours]
  cmd = git-checkout --ours ${MERGED}
  trustExitCode = true
[mergetool.mergeours]
  cmd = git-merge-file --ours ${LOCAL} ${BASE} ${REMOTE} -p > ${MERGED}
  trustExitCode = true
[mergetool.keepours]
  cmd = sed -i '' -e '/^<<<<<<</d' -e '/^|||||||/,/^>>>>>>>/d' ${MERGED}
  trustExitCode = true
[mergetool.gettheirs]
  cmd = git-checkout --theirs ${MERGED}
  trustExitCode = true
[mergetool.mergetheirs]
  cmd = git-merge-file --theirs ${LOCAL} ${BASE} ${REMOTE} -p > ${MERGED}
  trustExitCode = true
[mergetool.keeptheirs]
  cmd = sed -i '' -e '/^<<<<<<</,/^=======/d' -e '/^>>>>>>>/d' ${MERGED}
  trustExitCode = true

The get(ours|theirs) tool just keeps the respective version of the file and throws away all of the changes from the other version (so no merging occurs).

The merge(ours|theirs) tool re-does the three way merge from the local, base, and remote versions of the file, choosing to resolve conflicts in the given direction. This has some caveats, specifically: it ignores the diff options that were passed to the merge command (such as algorithm and whitespace handling); does the merge cleanly from the original files (so any manual changes to the file are discarded, which could be good or bad); and has the advantage that it cannot be confused by diff markers that are supposed to be in the file.

The keep(ours|theirs) tool simply edits out the diff markers and enclosed sections, detecting them by regular expression. This has the advantage that it preserves the diff options from the merge command and allows you to resolve some conflicts by hand and then automatically resolve the rest. It has the disadvantage that if there are other conflict markers in the file it could get confused.

These are all used by running git mergetool -t (get|merge|keep)(ours|theirs) [<filename>] where if <filename> is not supplied it processes all conflicted files.

Generally speaking, assuming you know there are no diff markers to confuse the regular expression, the keep* variants of the command are the most powerful. If you leave the mergetool.keepBackup option unset or true then after the merge you can diff the *.orig file against the result of the merge to check that it makes sense. As an example, I run the following after the mergetool just to inspect the changes before committing:

for f in `find . -name '*.orig'`; do vimdiff $f ${f%.orig}; done

Note: If the merge.conflictstyle is not diff3 then the /^|||||||/ pattern in the sed rule needs to be /^=======/ instead.

Use:

System.Security.Principal.WindowsIdentity.GetCurrent().Name

That will be the logon name.

On macOS Mojave with Xcode 10.3, I got scary warnings from the gem route with or without -n /usr/local/bin:

xcodeproj's executable "xcodeproj" conflicts with /usr/local/bin/xcodeproj
Overwrite the executable? [yN] 

What works for me is still Homebrew, just

brew install cocoapods

It looks like you are entering a blank line after the body of the if statement. This is a cue to the interactive compiler that you are done with the block entirely, so it is not expecting any elif/else blocks. Try entering the code exactly like this, and only hit enter once after each line:

if guess == number:
    print('Congratulations! You guessed it.')
elif guess < number:
    pass # Your code here
else:
    pass # Your code here

My cause was different I referenced a web service then I got this message.

Then I changed my target .Net Framework 4.0 to .Net Framework 2.0 and re-refer my webservice. After a few changes problem solved. There is no error worked fine.

hope this helps!

You can use the Microsoft.VisualBasic namespace to find this helper function:

Replace(sourceString, "replacethis", "withthis", , , CompareMethod.Text)

I've tried a lot of things to let this work on Marshmallow and Lollipop. Finally i ended up moving the saved picture to the DCIM folder (new Google Photo app scan images only if they are inside this folder apparently)

public static File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")
         .format(System.currentTimeInMillis());
    File storageDir = new File(Environment
         .getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) + "/Camera/");
    if (!storageDir.exists())
        storageDir.mkdirs();
    File image = File.createTempFile(
            timeStamp,                   /* prefix */
            ".jpeg",                     /* suffix */
            storageDir                   /* directory */
    );
    return image;
}

And then the standard code for scanning files which you can find in the Google Developers site too.

public static void addPicToGallery(Context context, String photoPath) {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(photoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    context.sendBroadcast(mediaScanIntent);
}

Please remember that this folder could not be present in every device in the world and that starting from Marshmallow (API 23), you need to request the permission to WRITE_EXTERNAL_STORAGE to the user.

If you don't have borders, or have borders and want the spacing inside the cells, you can use padding, or line-height. As far as I know, margin has no effect on cells and rows.
A CSS property for spacing of cells is border-spacing, but it doesn't work on IE6/7 (so you can use it depending on your crowd).

If all else fails you can use the old cellspacing attribute in your markup - but this will also give you spacing between the columns. Some CSS reset suggest you should set it anyway to get cross-browser support:

/* tables still need cellspacing="0" in the markup */

I mostly use lstlistings in papers, but for coloured output (for slides) I use pygments instead.

Groupby can helps you:

grouped = data.groupby(['name'])

Then you can work with each group like with a dataframe for each participant. And DataFrameGroupBy object methods such as (apply, transform, aggregate, head, first, last) return a DataFrame object.

Or you can make list from grouped and get all DataFrame's by index:

l_grouped = list(grouped)

l_grouped[0][1] - DataFrame for first group with first name.

To manipulate the white space, use str_trim() in the stringr package. The package has manual dated Feb 15, 2013 and is in CRAN. The function can also handle string vectors.

install.packages("stringr", dependencies=TRUE)
require(stringr)
example(str_trim)
d4$clean2<-str_trim(d4$V2)

(Credit goes to commenter: R. Cotton)

To use the parent of an element use parentElement:

function selectedProduct(event){
  var target = event.target;
  var parent = target.parentElement;//parent of "target"
}

wrap you shared code into another function:

<script>
  function myFun () {
      //do something
  }

  $(document).ready(function(){
    //Load City by State
    $(document).on('change', '#billing_state_id', function() {
       myFun ();
    });   
    $(document).on('click', '#click_me', function() {
       //do something
       myFun();
    });   
  });
</script>

Use get_the_category() like this:

<?php
foreach((get_the_category()) as $category) { 
    echo $category->cat_name . ' '; 
} 
?>

It returns a list because a post can have more than one category.

The documentation also explains how to do this from outside the loop.

MySQL password expiry

Resetting the password will only solve the problem temporarily. From MySQL 5.7.4 to 5.7.10 (to encourage better security - see MySQL: Password Expiration Policy) the default default_password_lifetime variable value is 360 (1 year-ish). For those versions, if you make no changes to this variable (or to individual user accounts) all passwords expire after 360 days.

So from a script you might get the message: "Your password has expired. To log in you must change it using a client that supports expired passwords."

To stop automatic password expiry, log in as root (mysql -u root -p), then, for clients that automatically connect to the server (e.g. scripts.) change password expiration settings:

ALTER USER 'script'@'localhost' PASSWORD EXPIRE NEVER;

OR you can disable automatic password expiration for all users:

SET GLOBAL default_password_lifetime = 0;

As pointed out by Mertaydin in the comments, to make this permanent add the following line to a my.cnf file MySQL reads on startup, under the [mysqld] group of settings. The location of my.cnf depends on your setup (e.g. Windows, or Homebrew on OS X, or an installer), and whether you want this per-user on Unix or global:

[mysqld] default_password_lifetime = 0 (There may be other settings here too...)

See the MySQL docs on configuration files.

This error comes when you have not made migrations to your newly created table, So,firsty write command on cmd as: python manage.py makemigrations and then write another command for applying these migrations made by makemigrations command: python manage.py migrate

The Host Header tells the webserver which virtual host to use (if set up). You can even have the same virtual host using several aliases (= domains and wildcard-domains). In this case, you still have the possibility to read that header manually in your web app if you want to provide different behavior based on different domains addressed. This is possible because in your webserver you can (and if I'm not mistaken you must) set up one vhost to be the default host. This default vhost is used whenever the host header does not match any of the configured virtual hosts.

That means: You get it right, although saying "multiple hosts" may be somewhat misleading: The host (the addressed machine) is the same, what really gets resolved to the IP address are different domain names (including subdomains) that are also referred to as hostnames (but not hosts!).

Although not part of the question, a fun fact: This specification led to problems with SSL in early days because the web server has to deliver the certificate that corresponds to the domain the client has addressed. However, in order to know what certificate to use, the webserver should have known the addressed hostname in advance. But because the client sends that information only over the encrypted channel (which means: after the certificate has already been sent), the server had to assume you browsed the default host. That meant one ssl-secured domain per IP address / port-combination.

This has been overcome with Server Name Indication; however, that again breaks some privacy, as the server name is now transferred in plain text again, so every man-in-the-middle would see which hostname you are trying to connect to.

Although the webserver would know the hostname from Server Name Indication, the Host header is not obsolete, because the Server Name Indication information is only used within the TLS handshake. With an unsecured connection, there is no Server Name Indication at all, so the Host header is still valid (and necessary).

Another fun fact: Most webservers (if not all) reject your HTTP request if it does not contain exactly one Host header, even if it could be omitted because there is only the default vhost configured. That means the minimum required information in an http-(get-)request is the first line containing METHOD RESOURCE and PROTOCOL VERSION and at least the Host header, like this:

GET /someresource.html HTTP/1.1
Host: www.example.com

In the MDN Documentation on the "Host" header they actually phrase it like this:

A Host header field must be sent in all HTTP/1.1 request messages. A 400 (Bad Request) status code will be sent to any HTTP/1.1 request message that lacks a Host header field or contains more than one.

As mentioned by Darrel Miller, the complete specs can be found in RFC7230.

Since tuples are immutable, this will result in a new tuple. Just place it back where you got the old one.

sometuple + (someitem,)

This is a possible solution for you:

a = [15, 12, 10]
b = sorted(a)
print b # --> b = [10, 12, 15]
c = 13
for i in range(len(b)):
    if b[i] > c:
        break
d = b[:i] + [c] + b[i:]
print d # --> d = [10, 12, 13, 15]

dircache is "Deprecated since version 2.6: The dircache module has been removed in Python 3.0."

import dircache
list = dircache.listdir(pathname)
i = 0
check = len(list[0])
temp = []
count = len(list)
while count != 0:
  if len(list[i]) != check:
     temp.append(list[i-1])
     check = len(list[i])
  else:
    i = i + 1
    count = count - 1

print temp

Here is the solution that worked for me

=IF(H14<>"",NOW(),"")

Just adding another way for DataFrame expanded over all columns:

for column in df.columns:
   df = df[df[column]!=0]

Example:

def z_score(data,count):
   threshold=3
   for column in data.columns:
       mean = np.mean(data[column])
       std = np.std(data[column])
       for i in data[column]:
           zscore = (i-mean)/std
           if(np.abs(zscore)>threshold):
               count=count+1
               data = data[data[column]!=i]
   return data,count

"\n" works fine. If the input is coming from a multi-line textbox, the new line characters will be "\r\n", if this is replaced with "\n", it will work.

When I encountered the problem, the changes.xml document was malformed (missing an end tag). The fix was to edit the XML to make it well formed.

So checking that the XML is well formed can be important, especially when the release plugin does not complain about it.

Is this what you are trying to do?

# Our data
text <- c("F.US.CLE.V13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", 
"F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", 
"F.US.DL.U13", "F.US.DL.U13", "F.US.DL.U13", "F.US.DL.Z13", "F.US.DL.Z13"
)

#  Split into individual elements by the '.' character
#  Remember to escape it, because '.' by itself matches any single character
elems <- unlist( strsplit( text , "\\." ) )

#  We know the dataframe should have 4 columns, so make a matrix
m <- matrix( elems , ncol = 4 , byrow = TRUE )

#  Coerce to data.frame - head() is just to illustrate the top portion
head( as.data.frame( m ) )
#  V1 V2  V3  V4
#1  F US CLE V13
#2  F US CA6 U13
#3  F US CA6 U13
#4  F US CA6 U13
#5  F US CA6 U13
#6  F US CA6 U13

it depends where is your Data folder

To get the directory where the .exe file is:

AppDomain.CurrentDomain.BaseDirectory

To get the current directory:

Environment.CurrentDirectory

Then you can concatenate your directory path (@"\Data\Names.txt")

Look, every answer above that proposes writing a string replacement by a constant string can only be wrong. Why? Because you don't respect the region settings of Windows! Windows assures the user to have the freedom to set whatever separator character s/he wants. S/He can open up the control panel, go into the region panel, click on advanced and change the character at any time. Even during your program run. Think of this. A good solution must be aware of this.

So, first you will have to ask yourself, where this number is coming from, that you want to parse. If it's coming from input in the .NET Framework no problem, because it will be in the same format. But maybe it was coming from outside, maybe from a external server, maybe from an old DB that only supports string properties. There, the db admin should have given a rule in which format the numbers are to be stored. If you know for example that it will be an US DB with US format you can use this piece of code:

CultureInfo usCulture = new CultureInfo("en-US");
NumberFormatInfo dbNumberFormat = usCulture.NumberFormat;
decimal number = decimal.Parse(db.numberString, dbNumberFormat);

This will work fine anywhere on the world. And please don't use 'Convert.ToXxxx'. The 'Convert' class is thought only as a base for conversions in any direction. Besides: You may use the similar mechanism for DateTimes too.

If you want to set options temporarily to display one large DataFrame, you can use option_context:

with pd.option_context('display.max_rows', None, 'display.max_columns', None):
    print (df)

Option values are restored automatically when you exit the with block.

Use Int32.TryParse.

 int integer;
 Int32.TryParse(Textbox.Text, out integer)

It will return a bool so you can see if they entered a valid integer.

As you are reading the binary file, you need to unpack it into a integer, so use struct module for that

import struct
fin = open("hi.bmp", "rb")
firm = fin.read(2)  
file_size, = struct.unpack("i",fin.read(4))

Note: If you are using Bootstrap + AngularJS + UI Bootstrap, .left .right and .next classes are never added. Using the example at the following link and the CSS from Robert McKee answer works. I wanted to comment because it took 3 days to find a full solution. Hope this helps others!

https://angular-ui.github.io/bootstrap/#/carousel

Code snip from UI Bootstrap Demo at the above link.

angular.module('ui.bootstrap.demo').controller('CarouselDemoCtrl', function ($scope) {
  $scope.myInterval = 5000;
  var slides = $scope.slides = [];
  $scope.addSlide = function() {
    var newWidth = 600 + slides.length + 1;
    slides.push({
      image: 'http://placekitten.com/' + newWidth + '/300',
      text: ['More','Extra','Lots of','Surplus'][slides.length % 4] + ' ' +
        ['Cats', 'Kittys', 'Felines', 'Cutes'][slides.length % 4]
    });
  };
  for (var i=0; i<4; i++) {
    $scope.addSlide();
  }
});

Html From UI Bootstrap, Notice I added the .fade class to the example.

<div ng-controller="CarouselDemoCtrl">
    <div style="height: 305px">
        <carousel class="fade" interval="myInterval">
          <slide ng-repeat="slide in slides" active="slide.active">
            <img ng-src="{{slide.image}}" style="margin:auto;">
            <div class="carousel-caption">
              <h4>Slide {{$index}}</h4>
              <p>{{slide.text}}</p>
            </div>
          </slide>
        </carousel>
    </div>
</div>

I needed including newlines and including the brackets

i think you should use hidden better.

activityIndicator.hidden = YES

What Jeremiah said, plus the compiler issues the warning because the production:

*src ="anotherstring";

says: take the address of "anotherstring" -- "anotherstring" IS a char pointer -- and store that pointer indirect through src (*src = ... ) into the first char of the string "abcdef..." The warning might be baffling because there is nowhere in your code any mention of any integer: the warning seems nonsensical. But, out of sight behind the curtain, is the rule that "int" and "char" are synonymous in terms of storage: both occupy the same number of bits. The compiler doesn't differentiate when it issues the warning that you are storing into an integer. Which, BTW, is perfectly OK and legal but probably not exactly what you want in this code.

After a bit of time (and more searching), I found this blog entry by Jomo Fisher.

One of the recent problems we’ve seen is that, because of the support for side-by-side runtimes, .NET 4.0 has changed the way that it binds to older mixed-mode assemblies. These assemblies are, for example, those that are compiled from C++\CLI. Currently available DirectX assemblies are mixed mode. If you see a message like this then you know you have run into the issue:

Mixed mode assembly is built against version 'v1.1.4322' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

[Snip]

The good news for applications is that you have the option of falling back to .NET 2.0 era binding for these assemblies by setting an app.config flag like so:

<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0"/>
</startup>

So it looks like the way the runtime loads mixed-mode assemblies has changed. I can't find any details about this change, or why it was done. But the useLegacyV2RuntimeActivationPolicy attribute reverts back to CLR 2.0 loading.

'' encloses single char, while "" encloses a String.

Change

y = 'hello';

-->

y = "hello";

If you want to filter y active accounts add this to Harvey's code:

 UserPrincipal userPrin = new UserPrincipal(context);
 userPrin.Enabled = true;

after the first using. Then add

  searcher.QueryFilter = userPrin;

before the find all. And that should get you the active ones.

You don't have to test the dataset.

The Fill() method returns the # of rows added.

See DbDataAdapter.Fill Method (DataSet)

In recent versions of eclipse the fix is slightly different...

1. Right click and select Project Properties
2. Select Project Facets
3. If necessary, click "Convert to faceted form"
4. Select "Java" facet
5. Click OK

try something like

public static Document loadXML(String xml) throws Exception
{
   DocumentBuilderFactory fctr = DocumentBuilderFactory.newInstance();
   DocumentBuilder bldr = fctr.newDocumentBuilder();
   InputSource insrc = new InputSource(new StringReader(xml));
   return bldr.parse(insrc);

apue.h dependency was still missing in my /usr/local/include after I managed to fix this problem on Mac OS Catalina following the instructions of this answer

I downloaded the dependency manually from git and placed it in /usr/local/include

Replace

volume = (4 / 3) Math.PI * Math.pow(radius, 3);

With:

volume = (4 * Math.PI * Math.pow(radius, 3)) / 3;

Use this function. It works like a charm. replace "|" with the char to explode/split and the values 1,2,3,etc are based on the number of entries in the data-set: Value_ONE|Value_TWO|Value_THREE.

SUBSTRING_INDEX(SUBSTRING_INDEX(`tblNAME`.`tblFIELD`, '|', 1), '|', -1) AS PSI,
SUBSTRING_INDEX(SUBSTRING_INDEX(`tblNAME`.`tblFIELD`, '|', 2), '|', -1) AS GPM,
SUBSTRING_INDEX(SUBSTRING_INDEX(`tblNAME`.`tblFIELD`, '|', 3), '|', -1) AS LIQUID

I hope this helps.

You could parse the response body like this:

parsed_body = JSON.parse(response.body)

Then you can make your assertions against that parsed content.

parsed_body["foo"].should == "bar"

Since vertical-align works as expected on a td, you could put a single celled table in the div to align its content.

<div>
    <table style="width: 100%; height: 100%;"><tr><td style="vertical-align: middle; text-align: center">
        Aligned content here...
    </td></tr></table>
</div>

Clunky, but works as far as I can tell. It might not have the drawbacks of the other workarounds.

To modify the float output do this:

df= pd.DataFrame(range(5), columns=['a'])
df.a = df.a.astype(float)
df

Out[33]:

          a
0 0.0000000
1 1.0000000
2 2.0000000
3 3.0000000
4 4.0000000

pd.options.display.float_format = '{:,.0f}'.format
df

Out[35]:

   a
0  0
1  1
2  2
3  3
4  4

There's the more general but perhaps not as helpful to you Wireshark.

One of the SO server sites might be better suited for your question. In fact, it's already been asked on SuperUser.

For me, only this solution worked for multiline text:

.circle-multiline {
    display: table-cell;
    height: 200px;
    width: 200px;
    text-align: center;
    vertical-align: middle;
    border-radius: 50%;
    background: yellow;
}

this worked for me :)

select * from Common

where

common_id not in (select ISNULL(common_id,'dummy-data') from Table1)

and common_id not in (select ISNULL(common_id,'dummy-data') from Table2)

I got a simpler solution which worked perfectly for me :

Drawable drawable = ContextCompat.getDrawable(getApplicationContext(),R.drawable.change_pass);
        toolbar.setOverflowIcon(drawable);

You can do:

#if MACRO0
    //code...
#elif MACRO1
    //code...
#endif

…where the identifier can be:

    __linux__       Defined on Linux
    __sun           Defined on Solaris
    __FreeBSD__     Defined on FreeBSD
    __NetBSD__      Defined on NetBSD
    __OpenBSD__     Defined on OpenBSD
    __APPLE__       Defined on Mac OS X
    __hpux          Defined on HP-UX
    __osf__         Defined on Tru64 UNIX (formerly DEC OSF1)
    __sgi           Defined on Irix
    _AIX            Defined on AIX
    _WIN32          Defined on Windows

if exist <insert file name here> (
    rem file exists
) else (
    rem file doesn't exist
)

Or on a single line (if only a single action needs to occur):

if exist <insert file name here> <action>

for example, this opens notepad on autoexec.bat, if the file exists:

if exist c:\autoexec.bat notepad c:\autoexec.bat

Had a need for similar functionality myself, so after much hair pulling I came up with the function below

/**
 * Fetches angle relative to screen centre point
 * where 3 O'Clock is 0 and 12 O'Clock is 270 degrees
 * 
 * @param screenPoint
 * @return angle in degress from 0-360.
 */
public double getAngle(Point screenPoint) {
    double dx = screenPoint.getX() - mCentreX;
    // Minus to correct for coord re-mapping
    double dy = -(screenPoint.getY() - mCentreY);

    double inRads = Math.atan2(dy, dx);

    // We need to map to coord system when 0 degree is at 3 O'clock, 270 at 12 O'clock
    if (inRads < 0)
        inRads = Math.abs(inRads);
    else
        inRads = 2 * Math.PI - inRads;

    return Math.toDegrees(inRads);
}

Note: This example uses the draft version of the Flexible Box Layout Module. It has been superseded by the incompatible modern specification.

Center the child elements of a div box by using the box-align and box-pack properties together.

Example:

div
{
width:350px;
height:100px;
border:1px solid black;

/* Internet Explorer 10 */
display:-ms-flexbox;
-ms-flex-pack:center;
-ms-flex-align:center;

/* Firefox */
display:-moz-box;
-moz-box-pack:center;
-moz-box-align:center;

/* Safari, Opera, and Chrome */
display:-webkit-box;
-webkit-box-pack:center;
-webkit-box-align:center;

/* W3C */
display:box;
box-pack:center;
box-align:center;

On Yosemite, install vim using brew and the override-system-vi option. This will automatically install vim with the features of the 'huge' vim install.

brew install vim --with-override-system-vi

The output of this command will show you where brew installed vim. In that folder, go down into /bin/vim to actually run vim. This is your command to run vim from any folder:

/usr/local/Cellar/vim/7.4.873/bin/vim

Then alias this command by adding the following line in your .bashrc:

alias vim="/usr/local/Cellar/vim/7.4.873/bin/vim"

EDIT: Brew flag --override-system-vi has been deprecated. Changed for --with-override-system-vi. Source: https://github.com/Shougo/neocomplete.vim/issues/401

Using changeit for the password is important too.

This command finally worked for me(with jetty):

 keytool -genkey -keyalg RSA -alias selfsigned -keystore keystore.jks -storepass changeit -validity 360 -keysize 2048

var full_url = document.URL; // Get current url
var url_array = full_url.split('/') // Split the string into an array with / as separator
var last_segment = url_array[url_array.length-1];  // Get the last part of the array (-1)
alert( last_segment ); // Alert last segment

Option #1

Instead of picking the binary/raw data into a variable and then writing, you can use CURLOPT_FILE option to directly show a file to the curl for the downloading.

Here is the function:

// takes URL of image and Path for the image as parameter
function download_image1($image_url, $image_file){
    $fp = fopen ($image_file, 'w+');              // open file handle

    $ch = curl_init($image_url);
    // curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want
    curl_setopt($ch, CURLOPT_FILE, $fp);          // output to file
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 1000);      // some large value to allow curl to run for a long time
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
    // curl_setopt($ch, CURLOPT_VERBOSE, true);   // Enable this line to see debug prints
    curl_exec($ch);

    curl_close($ch);                              // closing curl handle
    fclose($fp);                                  // closing file handle
}

And here is how you should call it:

// test the download function
download_image1("http://www.gravatar.com/avatar/10773ae6687b55736e171c038b4228d2", "local_image1.jpg");

Option #2

Now, If you want to download a very large file, that case above function may not become handy. You can use the below function this time for handling a big file. Also, you can print progress(in % or in any other format) if you want. Below function is implemented using a callback function that writes a chunk of data in to the file in to the progress of downloading.

// takes URL of image and Path for the image as parameter
function download_image2($image_url){
    $ch = curl_init($image_url);
    // curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // enable if you want
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_TIMEOUT, 1000);      // some large value to allow curl to run for a long time
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
    curl_setopt($ch, CURLOPT_WRITEFUNCTION, "curl_callback");
    // curl_setopt($ch, CURLOPT_VERBOSE, true);   // Enable this line to see debug prints
    curl_exec($ch);

    curl_close($ch);                              // closing curl handle
}

/** callback function for curl */
function curl_callback($ch, $bytes){
    global $fp;
    $len = fwrite($fp, $bytes);
    // if you want, you can use any progress printing here
    return $len;
}

And here is how to call this function:

// test the download function
$image_file = "local_image2.jpg";
$fp = fopen ($image_file, 'w+');              // open file handle
download_image2("http://www.gravatar.com/avatar/10773ae6687b55736e171c038b4228d2");
fclose($fp);                                  // closing file handle

Completely relative:

<img src="kitten.png"/>

this is a relative path indeed.

Absolute in all respects:

<img src="http://www.foo.com/images/kitten.png"/>

this is a URL, and it can be seen in some way as an absolute path, but it's not representative for this matter.

The difference between relative and absolute paths is that when using relative paths you take as reference the current working directory while with absolute paths you refer to a certain, well known directory. Relative paths are useful when you make some program that has to use resources from certain folders that can be opened using the working directory as a starting point.

Example of relative paths:

• image.png, which is the equivalent to .\image.png (in Windows) or ./image.png (anywhere else). The . explicitly specifies that you're expressing a path relative to the current working directory, but this is implied whenever the path doesn't begin at a root directory (designated with a slash), so you don't have to use it necessarily (except in certain contexts where a default directory (or a list of directories to search) will be applied unless you explicitly specify some directory).

• ..\images\image2.jpg This way you can access resources from directories one step up the folders tree.  The ..\ means you've exited the current folder, entering the directory that contains both the working and images folders.  Again, use \ in Windows and / anywhere else.

Example of absolute paths:

• D:\documents\something.doc
• E:\music\good_music.mp3

and so on.

get one column in the distinct select and ignore null values:

 var items = db.table.Where(p => p.id!=null).GroupBy(p => p.id)
                                .Select(grp => grp.First().id)
                                .ToList();

In DB2, using single quotes instead of your double quotes will work. So that could translate the same in Oracle..

SELECT CustomerName AS Customer, '' AS Contact 
FROM Customers;

I found a good Blog post about the behaviour of Hibernate in this kind of object mappings: http://blog.eyallupu.com/2010/06/hibernate-exception-simultaneously.html

This won't fail on Linq2Objects, but it will fail for Linq2SQL, so I am assuming that you are talking about the SQL provider or something similar.

The reason has to do with the way that the SQL provider handles your lambda expression. It doesn't take it as a function Func<P,T>, but an expression Expression<Func<P,T>>. It takes that expression tree and translates it so an actual SQL statement, which it sends off to the server.

The translator knows how to handle basic operators, but it doesn't know how to handle methods on objects. It doesn't know that IsNullOrEmpty(x) translates to return x == null || x == string.empty. That has to be done explicitly for the translation to SQL to take place.

Works in Net Core 2.1

    var file = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot", "email", "EmailRegister.htm");

    string SendData = System.IO.File.ReadAllText(file);

Use the SQLCMD utility.

http://technet.microsoft.com/en-us/library/ms162773.aspx

There is a connect statement that allows you to swing from database server A to server B in the same batch.

:Connect server_name[\instance_name] [-l timeout] [-U user_name [-P password]] Connects to an instance of SQL Server. Also closes the current connection.

On the other hand, if you are familiar with PowerShell, you can programmatic do the same.

While it's possible to call open(filename, 'rb') and check through the binary image headers for the dimensions, it seems much more useful to install PIL and spend your time writing great new software! You gain greater file format support and the reliability that comes from widespread usage. From the PIL documentation, it appears that the code you would need to complete your task would be:

from PIL import Image
im = Image.open('filename.png')
print 'width: %d - height: %d' % im.size # returns (width, height) tuple

As for writing code yourself, I'm not aware of a module in the Python standard library that will do what you want. You'll have to open() the image in binary mode and start decoding it yourself. You can read about the formats at:

• PNG file format documentation
• Notes on the JPEG file format headers

I recently ran into an issue with IEnumerable v. IQueryable. The algorithm being used first performed an IQueryable query to obtain a set of results. These were then passed to a foreach loop, with the items instantiated as an Entity Framework (EF) class. This EF class was then used in the from clause of a Linq to Entity query, causing the result to be IEnumerable.

I'm fairly new to EF and Linq for Entities, so it took a while to figure out what the bottleneck was. Using MiniProfiling, I found the query and then converted all of the individual operations to a single IQueryable Linq for Entities query. The IEnumerable took 15 seconds and the IQueryable took 0.5 seconds to execute. There were three tables involved and, after reading this, I believe that the IEnumerable query was actually forming a three table cross-product and filtering the results.

Try to use IQueryables as a rule-of-thumb and profile your work to make your changes measurable.

JavaScript file paths

When in script, paths are relative to displayed page

to make things easier you can print out a simple js declaration like this and using this variable all across your scripts:

Solution, which was employed on StackOverflow around Feb 2010:

<script type="text/javascript">
   var imagePath = 'http://sstatic.net/so/img/';
</script>

If you were visiting this page around 2010 you could just have a look at StackOverflow's html source, you could find this badass one-liner [formatted to 3 lines :) ] in the <head /> section

These examples are fine, I wanted to point out that you can achieve the same result using an Intent. The intent opens the Contacts app with the fields you provide already filled in.

It's up to the user to save the newly created contact.

You can read about it here: https://developer.android.com/training/contacts-provider/modify-data.html

Intent contactIntent = new Intent(ContactsContract.Intents.Insert.ACTION);
contactIntent.setType(ContactsContract.RawContacts.CONTENT_TYPE);

contactIntent
        .putExtra(ContactsContract.Intents.Insert.NAME, "Contact Name")
        .putExtra(ContactsContract.Intents.Insert.PHONE, "5555555555");

startActivityForResult(contactIntent, 1);

startActivityForResult() gives you the opportunity to see the result.

I've noticed the resultCode works on >5.0 devices,

but I have an older Samsung (<5) that always returns RESULT_CANCELLED (0).

Which I understand is the default return if an activity doesn't expect to return anything.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);

    if (requestCode == 1)
    {
        if (resultCode == Activity.RESULT_OK) {
            Toast.makeText(this, "Added Contact", Toast.LENGTH_SHORT).show();
        }
        if (resultCode == Activity.RESULT_CANCELED) {
            Toast.makeText(this, "Cancelled Added Contact", Toast.LENGTH_SHORT).show();
        }
    }
}

<a href="#Foo" onclick="return runMyFunction();">Do it!</a>

and

function runMyFunction() {
  //code
  return true;
}

This way you will have youf function executed AND you will follow the link AND you will follow the link exactly after your function was successfully run.

I think the following makes a bit more sense for print strings in reverse, but maybe that's just me:

for char in reversed( myString ):  
  print( char, end = "" )

No need to use fancy unicode char exmaples to show the difference. Here's one simple example I found out today which is surprising, consisting of only ASCII characters.

According to the ASCII table, 0 (0x48) is smaller than _ (0x95) when compared ordinally. InvariantCulture would say the opposite (PowerShell code below):

PS> [System.StringComparer]::Ordinal.Compare("_", "0")
47
PS> [System.StringComparer]::InvariantCulture.Compare("_", "0")
-1

If using g++, make sure that you are not running gcc instead

revalidate() just request to layout the container, when you experienced simply call revalidate() works, it could be caused by the updating of child components bounds triggers the repaint() when their bounds are changed during the re-layout. In the case you mentioned, only component removed and no component bounds are changed, this case no repaint() is "accidentally" triggered.

Lets say your data is -

data = {'a': [ [1, 2] ], 'b': [ [3, 4] ],'c':[ [5,6]] }

You can use the data.items() method to get the dictionary elements. Note, in django templates we do NOT put (). Also some users mentioned values[0] does not work, if that is the case then try values.items.

<table>
    <tr>
        <td>a</td>
        <td>b</td>
        <td>c</td>
    </tr>

    {% for key, values in data.items %}
    <tr>
        <td>{{key}}</td>
        {% for v in values[0] %}
        <td>{{v}}</td>
        {% endfor %}
    </tr>
    {% endfor %}
</table>

Am pretty sure you can extend this logic to your specific dict.

To iterate over dict keys in a sorted order - First we sort in python then iterate & render in django template.

return render_to_response('some_page.html', {'data': sorted(data.items())})

In template file:

{% for key, value in data %}
    <tr>
        <td> Key: {{ key }} </td> 
        <td> Value: {{ value }} </td>
    </tr>
{% endfor %}

We now have a more modern way to do this work.

java.time

The java.time framework is bundled with Java 8 and later. See Tutorial. These new classes are inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project. They are a vast improvement over the troublesome old classes, java.util.Date/.Calendar et al.

Note that the 3-4 letter codes like EDT are neither standardized nor unique. Avoid them whenever possible. Learn to use ISO 8601 standard formats instead. The java.time framework may take a stab at translating, but many of the commonly used codes have duplicate values.

By the way, note how java.time by default generates strings using the ISO 8601 formats but extended by appending the name of the time zone in brackets.

String input = "Thu Jun 18 20:56:02 EDT 2009";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern ( "EEE MMM d HH:mm:ss zzz yyyy" , Locale.ENGLISH );
ZonedDateTime zdt = formatter.parse ( input , ZonedDateTime :: from );

Dump to console.

System.out.println ( "zdt : " + zdt );

When run.

zdt : 2009-06-18T20:56:02-04:00[America/New_York]

Adjust Time Zone

For fun let's adjust to the India time zone.

ZonedDateTime zdtKolkata = zdt.withZoneSameInstant ( ZoneId.of ( "Asia/Kolkata" ) );

zdtKolkata : 2009-06-19T06:26:02+05:30[Asia/Kolkata]

Convert to j.u.Date

If you really need a java.util.Date object for use with classes not yet updated to the java.time types, convert. Note that you are losing the assigned time zone, but have the same moment automatically adjusted to UTC.

java.util.Date date = java.util.Date.from( zdt.toInstant() );

In a new sheet (where you want to create a new pivot table) press the key combination (Alt+D+P). In the list of data source options choose "Microsoft Excel list of database". Click Next and select the pivot table that you want to use as a source (select starting with the actual headers of the fields). I assume that this range is rather static and if you refresh the source pivot and it changes it's size you would have to re-size the range as well. Hope this helps.

Adding a solution here for a different problem, but one that manifests with the same error... Take care when constructing json on the fly (as api responses or whatever) to escape literal double quotes in your string members. You may be consuming your own malformed json.

Just had same issue. In Python 3, Binary modes 'wb', 'rb' must be specified whereas in Python 2x, they are not needed. When you follow tutorials that are based on Python 2x, that's why you are here.

import pickle

class MyUser(object):
    def __init__(self,name):
        self.name = name

user = MyUser('Peter')

print("Before serialization: ")
print(user.name)
print("------------")
serialized = pickle.dumps(user)
filename = 'serialized.native'

with open(filename,'wb') as file_object:
    file_object.write(serialized)

with open(filename,'rb') as file_object:
    raw_data = file_object.read()

deserialized = pickle.loads(raw_data)


print("Loading from serialized file: ")
user2 = deserialized
print(user2.name)

As the original question does not state which NuGet frontend should be used, I would like to mention that NuGet 3.5 adds support for updating to a specific version via the command line client (which works for downgrades, too):

NuGet.exe update Common.Logging -Version 1.2.0

I know you're using jQuery but for those who want a pure Javascript solution:

        var e = form.elements[i];
        if(!e.name || !e.value) continue; // Shortcut, may not be suitable for values = 0 (considered as false)
        switch (e.type) {
