It's very easy to solve it without url hacks, with CloudFront help.

• Create S3 bucket, for example: react
• Create CloudFront distributions with these settings:
  • Default Root Object: index.html
  • Origin Domain Name: S3 bucket domain, for example: react.s3.amazonaws.com
• Go to Error Pages tab, click on Create Custom Error Response:
  • HTTP Error Code: 403: Forbidden (404: Not Found, in case of S3 Static Website)
  • Customize Error Response: Yes
  • Response Page Path: /index.html
  • HTTP Response Code: 200: OK
  • Click on Create

You have to add this line just before loop

    MyFile = Dir

If your app is a system app,you can use PowerManager.goToSleep() to turn screen off,you requires a special permission

before you use goToSleep(), you need use reflection just like:

public static void goToSleep(Context context) {
    PowerManager powerManager= (PowerManager)context.getSystemService(Context.POWER_SERVICE);
    try {
        powerManager.getClass().getMethod("goToSleep", new Class[]{long.class}).invoke(powerManager, SystemClock.uptimeMillis());
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    } catch (NoSuchMethodException e) {
        e.printStackTrace();
    }
}

Now,you can use goToSleep() to turn screen off.

This is what happens when the power key is pressed to turn off the screen.

To get the label of a specific option in a dropdown yo can ty this --

$('.class_of_dropdown > option[value='value_to_be_searched']').html();

or

$('#id_of_dropdown > option[value='value_to_be_Searched']').html();

First we can make use of git stash list to get all stash items:

$git stash list
stash@{0}: WIP on ...
stash@{1}: WIP on ....
stash@{2}: WIP on ...

Then we can make use of git stash show stash@{N} to check the files under a specific stash N. If we fire it then we may get:

$ git stash show stash@{2}
fatal: ambiguous argument 'stash@2': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

The reason for this may be that the shell is eating up curly braces and git sees stash@2 and not stash@{2}. And to fix this we need to make use of single quotes for braces as:

git stash show stash@'{2'}
com/java/myproject/my-xml-impl.xml                     | 16 ++++++++--------
com/java/myproject/MyJavaClass.java                    | 16 ++++++++--------
etc.

If the formula already exists in a cell you can fill it down as follows:

• Select the cell containing the formula and press CTRL+SHIFT+DOWN to select the rest of the column (CTRL+SHIFT+END to select up to the last row where there is data)
• Fill down by pressing CTRL+D
• Use CTRL+UP to return up

On Mac, use CMD instead of CTRL.

An alternative if the formula is in the first cell of a column:

• Select the entire column by clicking the column header or selecting any cell in the column and pressing CTRL+SPACE
• Fill down by pressing CTRL+D

based from the answer of @SW4, you could also add a little animation at the end.

body > div{_x000D_
    border:1px solid grey;_x000D_
}_x000D_
html, body, #container {_x000D_
    height:100%;_x000D_
    width:100%;_x000D_
    margin:0;_x000D_
    padding:0;_x000D_
}_x000D_
#container {_x000D_
    overflow:hidden;_x000D_
    position:relative;_x000D_
}_x000D_
#hideMe {_x000D_
    -webkit-animation: cssAnimation 5s forwards; _x000D_
    animation: cssAnimation 5s forwards;_x000D_
}_x000D_
@keyframes cssAnimation {_x000D_
    0%   {opacity: 1;}_x000D_
    90%  {opacity: 1;}_x000D_
    100% {opacity: 0;}_x000D_
}_x000D_
@-webkit-keyframes cssAnimation {_x000D_
    0%   {opacity: 1;}_x000D_
    90%  {opacity: 1;}_x000D_
    100% {opacity: 0;}_x000D_
}

<div>_x000D_
<div id='container'>_x000D_
    <div id='hideMe'>Wait for it...</div>_x000D_
</div>_x000D_
</div>

Making the remaining 0.5 seconds to animate the opacity attribute. Just make sure to do the math if you're changing the length, in this case, 90% of 5 seconds leaves us 0.5 seconds to animate the opacity.

You could avoid explicit loops by taking the LINQ route:

sList.Any(s => s.Equals("ok"))

Note that, in addition to number of predictive variables, the Adjusted R-squared formula above also adjusts for sample size. A small sample will give a deceptively large R-squared.

Ping Yin & Xitao Fan, J. of Experimental Education 69(2): 203-224, "Estimating R-squared shrinkage in multiple regression", compares different methods for adjusting r-squared and concludes that the commonly-used ones quoted above are not good. They recommend the Olkin & Pratt formula.

However, I've seen some indication that population size has a much larger effect than any of these formulas indicate. I am not convinced that any of these formulas are good enough to allow you to compare regressions done with very different sample sizes (e.g., 2,000 vs. 200,000 samples; the standard formulas would make almost no sample-size-based adjustment). I would do some cross-validation to check the r-squared on each sample.

Don't declare the variable in the userform. Declare it as Public in the module.

Public pass As String

In the Userform

Private Sub CommandButton1_Click()
    pass = UserForm1.TextBox1
    Unload UserForm1
End Sub

In the Module

Public pass As String

Public Sub Login()
    '
    '~~> Rest of the code
    '
    UserForm1.Show
    driver.findElementByName("PASSWORD").SendKeys pass
    '
    '~~> Rest of the code
    '
End Sub

You might want to also add an additional check just before calling the driver.find... line?

If Len(Trim(pass)) <> 0 Then

This will ensure that a blank string is not passed.

In python 2.7, the / operator is integer division if inputs are integers.

If you want float division (which is something I always prefer), just use this special import:

from __future__ import division

See it here:

>>> 7 / 2
3
>>> from __future__ import division
>>> 7 / 2
3.5
>>>

Integer division is achieved by using //, and modulo by using %

>>> 7 % 2
1
>>> 7 // 2
3
>>>

EDIT

As commented by user2357112, this import has to be done before any other normal import.

SELECT CONVERT(CAST(column as BINARY) USING utf8) as column FROM table 

Here is the Latest solution of the problem:

In your CSS file write the following class called .clearfix along with the pseudo selector :after

.clearfix:after {
content: "";
display: table;
clear: both;
}

Then, in your HTML, add the .clearfix class to your parent Div. For example:

<div class="clearfix">
    <div></div>
    <div></div>
</div>

It should work always. You can call the class name as .group instead of .clearfix , as it will make the code more semantic. Note that, it is Not necessary to add the dot or even a space in the value of Content between the double quotation "".

Check out in here, worked well for me, with no limits in the output size, no omitted elements, even beyond 1000

Exporting large lists in R as .txt or .csv

Try my baby:

**

myApp.filter('inputSelected', function(){
  return function(formData){
    var keyArr = [];
    var word = [];
    Object.keys(formData).forEach(function(key){
    if (formData[key]){
        var keyCap = key.charAt(0).toUpperCase() + key.slice(1);
      for (var char = 0; char<keyCap.length; char++ ) {
        if (keyCap[char] == keyCap[char].toUpperCase()){
          var spacedLetter = ' '+ keyCap[char];
          word.push(spacedLetter);
        }
        else {
          word.push(keyCap[char]);
        }
      }
    }
    keyArr.push(word.join(''))
    word = [];
    })
    return keyArr.toString();
  }
})

**

Then for any ng-model with checkboxes, it will return a string of all the input you selected:

<label for="Heard about ITN">How did you hear about ITN?: *</label><br>
<label class="checkbox-inline"><input ng-model="formData.heardAboutItn.brotherOrSister" type="checkbox" >Brother or Sister</label>
<label class="checkbox-inline"><input ng-model="formData.heardAboutItn.friendOrAcquaintance" type="checkbox" >Friend or Acquaintance</label>


{{formData.heardAboutItn | inputSelected }}

//returns Brother or Sister, Friend or Acquaintance

Three approaches I can think of:

1. Create a custom table cell that lays out the view of the entire cell in the manner that you desire

2. Instead of adding the image to the image view, clear the subviews of the image view, create a custom view that adds an UIImageView for the image and another view, perhaps a simple UIView that provides the desired spacing, and add it as a subview of the image view.

3. I want to suggest that you manipulate the UIImageView directly to set a fixed size/padding, but I'm nowhere near Xcode so I can't confirm whether/how this would work.

Does that make sense?

I think you should make a class for this anonymous type. That'd be the most sensible thing to do in my opinion. But if you really don't want to, you could use dynamics:

public void LogEmployees (IEnumerable<dynamic> list)
{
    foreach (dynamic item in list)
    {
        string name = item.Name;
        int id = item.Id;
    }
}

Note that this is not strongly typed, so if, for example, Name changes to EmployeeName, you won't know there's a problem until runtime.

You can also do like this:

  var mocha = require('mocha')
  var describe = mocha.describe
  var it = mocha.it
  var assert = require('chai').assert

  describe('#indexOf()', function() {
    it('should return -1 when not present', function() {
      assert.equal([1,2,3].indexOf(4), -1)
    })
  })

From the netstat output you can see the process is listening on address 127.0.0.1

tcp        0      0 127.0.0.1:9000          0.0.0.0:*  ...

from the exception message you can see that it tries to connect to address 127.0.1.1

java.net.ConnectException: Call From marta-komputer/127.0.1.1 to localhost:9000 failed ...

further in the exception it's mentionend

For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

on this page you find

Check that there isn't an entry for your hostname mapped to 127.0.0.1 or 127.0.1.1 in /etc/hosts (Ubuntu is notorious for this)

so the conclusion is to remove this line in your /etc/hosts

127.0.1.1       marta-komputer

I know the question is asking about your "csv" package implementation, but for your information, there are options that are much simpler — numpy, for instance.

import numpy as np
np.savetxt('data.csv', (col1_array, col2_array, col3_array), delimiter=',')

(This answer posted 6 years later, for posterity's sake.)

In a different case similar to what you're asking about, say you have two columns like this:

names = ['Player Name', 'Foo', 'Bar']
scores = ['Score', 250, 500]

You could save it like this:

np.savetxt('scores.csv', [p for p in zip(names, scores)], delimiter=',', fmt='%s')

scores.csv would look like this:

Player Name,Score
Foo,250
Bar,500

Here's a cleaner way to do it with macros:

#include <stdio.h>
#include <stdlib.h>

#define DOW(X, S)                                                         \
    X(Sunday) S X(Monday) S X(Tuesday) S X(Wednesday) S X(Thursday) S X(Friday) S X(Saturday)

#define COMMA ,

/* declare the enum */
#define DOW_ENUM(DOW) DOW
enum dow {
    DOW(DOW_ENUM, COMMA)
};

/* create an array of strings with the enum names... */
#define DOW_ARR(DOW ) [DOW] = #DOW
const char * const dow_str[] = {
    DOW(DOW_ARR, COMMA)
};

/* ...or create a switchy function. */
static const char * dowstr(int i)
{
#define DOW_CASE(D) case D: return #D

    switch(i) {
        DOW(DOW_CASE, ;);
    default: return NULL;
    }
}


int main(void)
{
    for(int i = 0; i < 7; i++)
        printf("[%d] = «%s»\n", i, dow_str[i]);
    printf("\n");
    for(int i = 0; i < 7; i++)
        printf("[%d] = «%s»\n", i, dowstr(i));
    return 0;
}

I'm not sure that this is totally portable b/w preprocessors, but it works with gcc.

This is c99 btw, so use c99 strict if you plug it into (the online compiler) ideone.

Previously posted solutions did not work for me. cell.getRawValue() returned the same formula as stated in the cell. The following function worked for me:

public void readFormula() throws IOException {
    FileInputStream fis = new FileInputStream("Path of your file");
    Workbook wb = new XSSFWorkbook(fis);
    Sheet sheet = wb.getSheetAt(0);
    FormulaEvaluator evaluator = wb.getCreationHelper().createFormulaEvaluator();

    CellReference cellReference = new CellReference("C2"); // pass the cell which contains the formula
    Row row = sheet.getRow(cellReference.getRow());
    Cell cell = row.getCell(cellReference.getCol());

    CellValue cellValue = evaluator.evaluate(cell);

    switch (cellValue.getCellType()) {
        case Cell.CELL_TYPE_BOOLEAN:
            System.out.println(cellValue.getBooleanValue());
            break;
        case Cell.CELL_TYPE_NUMERIC:
            System.out.println(cellValue.getNumberValue());
            break;
        case Cell.CELL_TYPE_STRING:
            System.out.println(cellValue.getStringValue());
            break;
        case Cell.CELL_TYPE_BLANK:
            break;
        case Cell.CELL_TYPE_ERROR:
            break;

        // CELL_TYPE_FORMULA will never happen
        case Cell.CELL_TYPE_FORMULA:
            break;
    }

}

A simple function to get UNIX Epoch time.

NOTE: This function assumes the input date time is in UTC format (Refer to comments here).

def utctimestamp(ts: str, DATETIME_FORMAT: str = "%d/%m/%Y"):
    import datetime, calendar
    ts = datetime.datetime.utcnow() if ts is None else datetime.datetime.strptime(ts, DATETIME_FORMAT)
    return calendar.timegm(ts.utctimetuple())

Usage:

>>> utctimestamp("01/12/2011")
1322697600
>>> utctimestamp("2011-12-01", "%Y-%m-%d")
1322697600

If i assume that your second code is the puppet config then i have a logical explaination, if the error and log files were create before, you can try this

sudo chown -R www-data:www-data /var/log/nginx;
sudo chmod -R 755 /var/log/nginx;

Go to your mysql bin directory and install mysql service again:

c:
cd \mysql\bin
mysqld-nt.exe --install

or if mysqld-nt.exe is missing (depending on version):

mysqld.exe --install

Then go to services, start the service and set it to automatic start.

If you have already the Query String as a string, you can also use simple string manipulation:

int pos = queryString.ToLower().IndexOf("parameter=");
if (pos >= 0)
{
    int pos_end = queryString.IndexOf("&", pos);
    if (pos_end >= 0)   // there are additional parameters after this one
        queryString = queryString.Substring(0, pos) + queryString.Substring(pos_end + 1);
    else
        if (pos == 0) // this one is the only parameter
            queryString = "";
        else        // this one is the last parameter
            queryString=queryString.Substring(0, pos - 1);
}

I used this way to make my project faster:

RichTextBox rcbCatalyst = new RichTextBox()
{
    Lines = arrayString
};
string text = rcbCatalyst.Text;
rcbCatalyst.Dispose();

return text;

RichTextBox.Text will automatically convert your array to a multiline string!

You can execute this command to enable nodejs:

scl enable rh-nodejs8 bash

Note: Check your node version.

The following works for me:

grep -P "[\x80-\xFF]" file.xml

Non-ASCII characters start at 0x80 and go to 0xFF when looking at bytes. Grep (and family) don't do Unicode processing to merge multi-byte characters into a single entity for regex matching as you seem to want. The -P option in my grep allows the use of \xdd escapes in character classes to accomplish what you want.

Using the dplyr package, if your data.frame is called df1:

library(dplyr)

df1 %>%
  select(A, B, E)

This can also be written without the %>% pipe as:

select(df1, A, B, E)

Looks like Users that are added in your Country object, are not already present in the DB. You need to use cascade to make sure that when Country is persisted, all User which are not there in data but are associated with Country also get persisted.

Below code should help:

@ManyToOne (cascade = CascadeType.ALL)
   @JoinColumn (name = "countryId")
   private Country country;

This is a slight variation, but PJW's solution didn't quite work for me:

java -version 2>&1 | head -n 1 | cut -d'"' -f2

just cut the string on the delimiter " (double quotes) and get the second field.

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').

Are you going to want to do a setInterval()?

setInterval(function(){get_fb();}, 10000);

Or:

setInterval(get_fb, 10000);

Or, if you want it to run only after successfully completing the call, you can set it up in your .ajax().success() callback:

function get_fb(){
    var feedback = $.ajax({
        type: "POST",
        url: "feedback.php",
        async: false
    }).success(function(){
        setTimeout(function(){get_fb();}, 10000);
    }).responseText;

    $('div.feedback-box').html(feedback);
}

Or use .ajax().complete() if you want it to run regardless of result:

function get_fb(){
    var feedback = $.ajax({
        type: "POST",
        url: "feedback.php",
        async: false
    }).complete(function(){
        setTimeout(function(){get_fb();}, 10000);
    }).responseText;

    $('div.feedback-box').html(feedback);
}

Here is a demonstration of the two. Note, the success works only once because jsfiddle is returning a 404 error on the ajax call.

Global variables are not extern nor static by default on C and C++. When you declare a variable as static, you are restricting it to the current source file. If you declare it as extern, you are saying that the variable exists, but are defined somewhere else, and if you don't have it defined elsewhere (without the extern keyword) you will get a link error (symbol not found).

Your code will break when you have more source files including that header, on link time you will have multiple references to varGlobal. If you declare it as static, then it will work with multiple sources (I mean, it will compile and link), but each source will have its own varGlobal.

What you can do in C++, that you can't in C, is to declare the variable as const on the header, like this:

const int varGlobal = 7;

And include in multiple sources, without breaking things at link time. The idea is to replace the old C style #define for constants.

If you need a global variable visible on multiple sources and not const, declare it as extern on the header, and then define it, this time without the extern keyword, on a source file:

Header included by multiple files:

extern int varGlobal;

In one of your source files:

int varGlobal = 7;

Have you seen the SqlDateTime object? use SqlDateTime.MinValue to get your minimum date (Jan 1 1753).

Try this:

String yourVal = "20.5";
float a = (Float.valueOf(yourVal)).floatValue(); 
System.out.println(a);

The history limit is a pane attribute that is fixed at the time of pane creation and cannot be changed for existing panes. The value is taken from the history-limit session option (the default value is 2000).

To create a pane with a different value you will need to set the appropriate history-limit option before creating the pane.

To establish a different default, you can put a line like the following in your .tmux.conf file:

set-option -g history-limit 3000

Note: Be careful setting a very large default value, it can easily consume lots of RAM if you create many panes.

For a new pane (or the initial pane in a new window) in an existing session, you can set that session’s history-limit. You might use a command like this (from a shell):

tmux set-option history-limit 5000 \; new-window

For (the initial pane of the initial window in) a new session you will need to set the “global” history-limit before creating the session:

tmux set-option -g history-limit 5000 \; new-session

Note: If you do not re-set the history-limit value, then the new value will be also used for other panes/windows/sessions created in the future; there is currently no direct way to create a single new pane/window/session with its own specific limit without (at least temporarily) changing history-limit (though show-option (especially in 1.7 and later) can help with retrieving the current value so that you restore it later).

This error arise from the fact that you are trying to define an object of shape (0,) as an object of shape (2,). If you append what you want without forcing it to be equal to result[0] there is no any issue:

b = np.append([result[0]], [1,2])

But when you define result[0] = b you are equating objects of different shapes, and you can not do this. What are you trying to do?

As a general point when using a search engine to search for SQL codes make sure you put the sqlcode e.g. -302 in quote marks - like "-302" otherwise the search engine will exclude all search results including the text 302, since the - sign is used to exclude results.

No reason. Maybe the person who coded it came from PHP. It has the same effect as if you had named it "_item" or "item" or "item$$".

As a suffix (like "item$", pronounced "items"), it can signify an observable such as a DOM element as a convention called "Finnish Notation" similar to the Hungarian Notation.

Where do you get the list of ids from in the first place? Since they are IDs in your database, did they come from some previous query?

When I have seen this in the past it has been because:-

1. a reference table is missing and the correct way would be to add the new table, put an attribute on that table and join to it
2. a list of ids is extracted from the database, and then used in a subsequent SQL statement (perhaps later or on another server or whatever). In this case, the answer is to never extract it from the database. Either store in a temporary table or just write one query.

I think there may be better ways to rework this code that just getting this SQL statement to work. If you provide more details you might get some ideas.

You can make a class for your global variable and then export this class like this:

export class CONSTANT {
    public static message2 = [
        { "NAME_REQUIRED": "Name is required" }
    ]

    public static message = {
        "NAME_REQUIRED": "Name is required",
    }
}

After creating and exporting your CONSTANT class, you should import this class in that class where you want to use, like this:

import { Component, OnInit                       } from '@angular/core';
import { CONSTANT                                } from '../../constants/dash-constant';


@Component({
  selector   : 'team-component',
  templateUrl: `../app/modules/dashboard/dashComponents/teamComponents/team.component.html`,
})

export class TeamComponent implements OnInit {
  constructor() {
    console.log(CONSTANT.message2[0].NAME_REQUIRED);
    console.log(CONSTANT.message.NAME_REQUIRED);
  }

  ngOnInit() {
    console.log("oninit");
    console.log(CONSTANT.message2[0].NAME_REQUIRED);
    console.log(CONSTANT.message.NAME_REQUIRED);
  }
}

You can use this either in constructor or ngOnInit(){}, or in any predefine methods.

perhaps you need to update your wget (~$ wget --version GNU Wget 1.14 built on linux-gnu.)

try this code

String data = "";
InputStream iStream = httpEntity.getContent();
BufferedReader br = new BufferedReader(new InputStreamReader(iStream, "utf8"));
StringBuffer sb = new StringBuffer();
String line = "";

while ((line = br.readLine()) != null) {
    sb.append(line);
}

data = sb.toString();
System.out.println(data);

I tried this code to accept files using Ajax and on submit file gets store using my php file. Code modified slightly to work. (Uploaded Files: PDF,JPG)

function verify1() {
    jQuery.ajax({
        type: 'POST',
        url:"functions.php",
        data: new FormData($("#infoForm1")[0]),
        processData: false,

        success: function(returnval) {
             $("#show1").html(returnval);
             $('#show1').show();
         }
    });
}

Just print the file details and check. You will get Output. If error let me know.

This recently happen to me when enabling JMX on two running tomcat service within Eclipse. I mistakenly put the same port for each server.

Simply give each jmx remote a different port

Server 1

-Dcom.sun.management.jmxremote.port=9000

Server 2

-Dcom.sun.management.jmxremote.port=9001

The Sun JVM requires a lot of memory for HotSpot and it maps in the runtime libraries in shared memory.

If memory is an issue consider using another JVM suitable for embedding. IBM has j9, and there is the Open Source "jamvm" which uses GNU classpath libraries. Also Sun has the Squeak JVM running on the SunSPOTS so there are alternatives.

You'll need to loop through your array elements, create a new DOM node for each and append it to your object.

var select = document.getElementById("selectNumber"); 
var options = ["1", "2", "3", "4", "5"]; 

for(var i = 0; i < options.length; i++) {
    var opt = options[i];
    var el = document.createElement("option");
    el.textContent = opt;
    el.value = opt;
    select.appendChild(el);
}?

Live example

I tried $count = $stmt->rowCount(); with Oracle 11.2 and it did not work. I decided to used a for loop as show below.

   $count =  "";
    $stmt =  $conn->prepare($sql);
    $stmt->execute();
   echo "<table border='1'>\n";
   while($row = $stmt->fetch(PDO::FETCH_OBJ)) {
        $count++;
        echo "<tr>\n";
    foreach ($row as $item) {
    echo "<td class='td2'>".($item !== null ? htmlentities($item, ENT_QUOTES):"&nbsp;")."</td>\n";
        } //foreach ends
        }// while ends
        echo "</table>\n";
       //echo " no of rows : ". oci_num_rows($stmt);
       //equivalent in pdo::prepare statement
       echo "no.of rows :".$count;

Spring security is a filter based framework, it plants a WALL(HttpFireWall) before your application in terms of proxy filters or spring managed beans. Your request has to pass through multiple filters to reach your API.

Sequence of execution in Spring Security

1. WebAsyncManagerIntegrationFilter Provides integration between the SecurityContext and Spring Web's WebAsyncManager.
   

2. SecurityContextPersistenceFilter This filter will only execute once per request, Populates the SecurityContextHolder with information obtained from the configured SecurityContextRepository prior to the request and stores it back in the repository once the request has completed and clearing the context holder.
   Request is checked for existing session. If new request, SecurityContext will be created else if request has session then existing security-context will be obtained from respository.

3. HeaderWriterFilter Filter implementation to add headers to the current response.

4. LogoutFilter If request url is /logout(for default configuration) or if request url mathces RequestMatcher configured in LogoutConfigurer then

   • clears security context.
   • invalidates the session
   • deletes all the cookies with cookie names configured in LogoutConfigurer
   • Redirects to default logout success url / or logout success url configured or invokes logoutSuccessHandler configured.

5. UsernamePasswordAuthenticationFilter

   • For any request url other than loginProcessingUrl this filter will not process further but filter chain just continues.
   • If requested URL is matches(must be HTTP POST) default /login or matches .loginProcessingUrl() configured in FormLoginConfigurer then UsernamePasswordAuthenticationFilter attempts authentication.
   • default login form parameters are username and password, can be overridden by usernameParameter(String), passwordParameter(String).
   • setting .loginPage() overrides defaults
   • While attempting authentication
     • an Authentication object(UsernamePasswordAuthenticationToken or any implementation of Authentication in case of your custom auth filter) is created.
     • and authenticationManager.authenticate(authToken) will be invoked
       
     • Note that we can configure any number of AuthenticationProvider authenticate method tries all auth providers and checks any of the auth provider supports authToken/authentication object, supporting auth provider will be used for authenticating. and returns Authentication object in case of successful authentication else throws AuthenticationException.
   • If authentication success session will be created and authenticationSuccessHandler will be invoked which redirects to the target url configured(default is /)
   • If authentication failed user becomes un-authenticated user and chain continues.

6. SecurityContextHolderAwareRequestFilter, if you are using it to install a Spring Security aware HttpServletRequestWrapper into your servlet container

7. AnonymousAuthenticationFilter Detects if there is no Authentication object in the SecurityContextHolder, if no authentication object found, creates Authentication object (AnonymousAuthenticationToken) with granted authority ROLE_ANONYMOUS. Here AnonymousAuthenticationToken facilitates identifying un-authenticated users subsequent requests.
   

DEBUG - /app/admin/app-config at position 9 of 12 in additional filter chain; firing Filter: 'AnonymousAuthenticationFilter'
DEBUG - Populated SecurityContextHolder with anonymous token: 'org.springframework.security.authentication.AnonymousAuthenticationToken@aeef7b36: Principal: anonymousUser; Credentials: [PROTECTED]; Authenticated: true; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@b364: RemoteIpAddress: 0:0:0:0:0:0:0:1; SessionId: null; Granted Authorities: ROLE_ANONYMOUS' 

8. ExceptionTranslationFilter, to catch any Spring Security exceptions so that either an HTTP error response can be returned or an appropriate AuthenticationEntryPoint can be launched

9. FilterSecurityInterceptor
   There will be FilterSecurityInterceptor which comes almost last in the filter chain which gets Authentication object from SecurityContext and gets granted authorities list(roles granted) and it will make a decision whether to allow this request to reach the requested resource or not, decision is made by matching with the allowed AntMatchers configured in HttpSecurityConfiguration.

Consider the exceptions 401-UnAuthorized and 403-Forbidden. These decisions will be done at the last in the filter chain

• Un authenticated user trying to access public resource - Allowed
  
• Un authenticated user trying to access secured resource - 401-UnAuthorized
  
• Authenticated user trying to access restricted resource(restricted for his role) - 403-Forbidden
  

Note: User Request flows not only in above mentioned filters, but there are others filters too not shown here.(ConcurrentSessionFilter,RequestCacheAwareFilter,SessionManagementFilter ...)
It will be different when you use your custom auth filter instead of UsernamePasswordAuthenticationFilter.
It will be different if you configure JWT auth filter and omit .formLogin() i.e, UsernamePasswordAuthenticationFilter it will become entirely different case.

From Documentation ordering of filters is given as

• ChannelProcessingFilter
• ConcurrentSessionFilter
• SecurityContextPersistenceFilter
• LogoutFilter
• X509AuthenticationFilter
• AbstractPreAuthenticatedProcessingFilter
• CasAuthenticationFilter
• UsernamePasswordAuthenticationFilter
• ConcurrentSessionFilter
• OpenIDAuthenticationFilter
• DefaultLoginPageGeneratingFilter
• DefaultLogoutPageGeneratingFilter
• ConcurrentSessionFilter
• DigestAuthenticationFilter
• BearerTokenAuthenticationFilter
• BasicAuthenticationFilter
• RequestCacheAwareFilter
• SecurityContextHolderAwareRequestFilter
• JaasApiIntegrationFilter
• RememberMeAuthenticationFilter
• AnonymousAuthenticationFilter
• SessionManagementFilter
• ExceptionTranslationFilter
• FilterSecurityInterceptor
• SwitchUserFilter

The MySQL dependency should be like the following syntax in the pom.xml file.

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.21</version>
    </dependency>

Make sure the syntax, groupId, artifactId, Version has included in the dependancy.

I used below to fix issue

yum install -y php-intl php-xsl php-opcache php-xml php-mcrypt php-gd php-devel php-mysql php-mbstring php-bcmath

I got same error. Because i used v4 alpha class names like carousel-control-next When i changed with v3, problem solved.

I would have your main thread pass a callback method to your first thread, and when it's done, it will invoke the callback method on the mainthread, which can launch the second thread. This keeps your main thread from hanging while its waiting for a Join or Waithandle. Passing methods as delegates is a useful thing to learn with C# anyway.

That's because you may using the repository cloned from the git or svn. Try to clone another new version and run it.

With an Android-powered device, you can develop and debug your Android applications just as you would on the emulator.

1. Declare your application as "debuggable" in AndroidManifest.xml.

<application
    android:debuggable="true"
    ... >
    ...
</application>

2. On your handset, navigate to Settings > Security and check Unknown sources

3. Go to Settings > Developer Options and check USB debugging
Note that if Developer Options is invisible you will need to navigate to Settings > About Phone and tap on Build number several times until you are notified that it has been unlocked.

4. Set up your system to detect your device.
Follow the instructions below for your OS:

Windows Users

Install the Google USB Driver from the ADT SDK Manager
(Support for: ADP1, ADP2, Verizon Droid, Nexus One, Nexus S).

For devices not listed above, install an OEM driver for your device

Mac OS X

Your device should automatically work; Go to the next step

Ubuntu Linux

Add a udev rules file that contains a USB configuration for each type of device you want to use for development. In the rules file, each device manufacturer is identified by a unique vendor ID, as specified by the ATTR{idVendor} property. For a list of vendor IDs, click here. To set up device detection on Ubuntu Linux:

1. Log in as root and create this file: /etc/udev/rules.d/51-android.rules.
2. Use this format to add each vendor to the file:
   SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", MODE="0666", GROUP="plugdev"
   In this example, the vendor ID is for HTC. The MODE assignment specifies read/write permissions, and GROUP defines which Unix group owns the device node.
3. Now execute: chmod a+r /etc/udev/rules.d/51-android.rules

Note: The rule syntax may vary slightly depending on your environment. Consult the udev documentation for your system as needed. For an overview of rule syntax, see this guide to writing udev rules.

5. Run the project with your connected device.

With Eclipse/ADT: run or debug your application as usual. You will be presented with a Device Chooser dialog that lists the available emulator(s) and connected device(s).

With ADB: issue commands with the -d flag to target your connected device.

You could use the methods described in this question (especially since you start off with an InputStream): Read/convert an InputStream to a String

In particular, if you don't want to rely on external libraries, you can try this answer, which reads the InputStream via an InputStreamReader into a char[] buffer and appends it into a StringBuilder.

I had a similar issue where I was getting an error for a member in the class that wasn't mapped to the db column, it was just a holder for a List of another entity. I changed List to ArrayList and the error went away. I know, I really shouldn't do that in a mapped entity, and that's what DTO's are for. Just wanted to share in case someone finds this thread and the answers above don't apply or help.

I know this question has been answered already, but I feel like there are a whole other set of pre-defined variables not covered by the ansible_* facts. This documentation page covers the directives (variables that modify Ansible's behavior), which I was looking for when I came across this page.

This includes some common and some specific use-case directives:

• become: Controls privilege escalation (sudo)
• delegate_to: run task on another host (like running on localhost)
• serial: allows you to run a play across a specific number/percentage of hosts before moving onto next set

This is working

<form name="myform" ng-submit="create()">
    <input type="number"
           name="price_field"
           ng-model="price"
           require
           ng-pattern="/^\d{0,9}(\.\d{1,9})?$/">
    <span  ng-show="myform.price_field.$error.pattern">Not valid number!</span>
    <input type="submit" class="btn">
 </form>

If you just use round then the two end numbers (1 and 9) will occur less frequently, to get an even distribution of integers between 1 and 9 then:

SELECT MOD(Round(DBMS_RANDOM.Value(1, 99)), 9) + 1 FROM DUAL

Before executing

git branch --delete <branch>

make sure you determine first what the exact name of the remote branch is by executing:

git ls-remote

This will tell you what to enter exactly for <branch> value. (branch is case sensitive!)

One other scenario which I encountered.

String imageName ="Hello" and then when it is passed into getIdentifier function as first argument, it will pass the name with string null termination and will always return zero. Pass this imageName.substring(0, imageName.length()-1)

PEP 8 advises the first form for readability. You can find it here.

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

I created a simple templated function, Sequence(), for generating sequences of numbers. The functionality follows the seq() function in R (link). The nice thing about this function is that it works for generating a variety of number sequences and types.

#include <iostream>
#include <vector>

template <typename T>
std::vector<T> Sequence(T min, T max, T by) {
  size_t n_elements = ((max - min) / by) + 1;
  std::vector<T> vec(n_elements);
  min -= by;
  for (size_t i = 0; i < vec.size(); ++i) {
    min += by;
    vec[i] = min;
  }
  return vec;
}

Example usage:

int main()
{
    auto vec = Sequence(0., 10., 0.5);
    for(auto &v : vec) {
        std::cout << v << std::endl;
    }
}

The only caveat is that all of the numbers should be of the same inferred type. In other words, for doubles or floats, include decimals for all of the inputs, as shown.

You can't easily decrypt the password from the hash string that you see. You should rather replace the hash string with a new one from a password that you do know.

There's a good howto here:

https://jakebillo.com/wordpress-phpass-generator-resetting-or-creating-a-new-admin-user/

Basically:

1. generate a new hash from a known password using e.g. http://scriptserver.mainframe8.com/wordpress_password_hasher.php, as described in the above link, or any other product that uses the phpass library,
2. use your DB interface (e.g. phpMyAdmin) to update the user_pass field with the new hash string.

If you have more users in this WordPress installation, you can also copy the hash string from one user whose password you know, to the other user (admin).

Hope this can help!

        defaultDate: "+1w",
        changeMonth: true,
        numberOfMonths: 2,

        onSelect: function( selectedDate ) {




            $( ".selector" ).datepicker({ defaultDate: +7 });
            var option = this.id == "from" ? "minDate" : "maxDate",


                instance = $( this ).data( "datepicker" ),
                date = $.datepicker.parseDate(
                    instance.settings.dateFormat ||
                    $.datepicker._defaults.dateFormat,
                    selectedDate, instance.settings );

            dates.not( this ).datepicker( "option", "dateFormat", 'yy-mm-dd' );


        }
    });
});

</script>

The problem is I am not sure how to restrict previous dates selection.

Meteor is a framework built ontop of node.js. It uses node.js to deploy but has several differences.

The key being it uses its own packaging system instead of node's module based system. It makes it easy to make web applications using Node. Node can be used for a variety of things and on its own is terrible at serving up dynamic web content. Meteor's libraries make all of this easy.

As this page also lists alternative tools I'll mention xpdf which has command line tools ready compiled for Linux/Windows/Mac. Supports transparency. Is free for commercial use - opposed to Ghostscript which has truly outrageous pricing.

In a test on a huge PDF file it was 7.5% faster than Ghostscript.

(It also has PDF to text and HTML converters)

You can use the clear method

List<string> test = new List<string>();
test.Clear();

Problem. My stored Claws Mail messages are wrapped as follows, and I am trying to extract the Subject lines:

Subject: [SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key molecular

Message-ID: <[email protected]>

Per A2 in this thread, How to use sed/grep to extract text between two words? the first expression, below, "works" as long as the matched text does not contain a newline:

grep -o -P '(?<=Subject: ).*(?=molecular)' corpus/01

[SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key

However, despite trying numerous variants (.+?; /s; ...), I could not get these to work:

grep -o -P '(?<=Subject: ).*(?=link)' corpus/01
grep -o -P '(?<=Subject: ).*(?=therapeutic)' corpus/01
etc.

Solution 1.

Per Extract text between two strings on different lines

sed -n '/Subject: /{:a;N;/Message-ID:/!ba; s/\n/ /g; s/\s\s*/ /g; s/.*Subject: \|Message-ID:.*//g;p}' corpus/01

which gives

[SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key molecular link in major cell growth pathway: Findings point to new potential therapeutic target in pancreatic cancer [mTORC1 Activator SLC38A9 Is Required to Efflux Essential Amino Acids from Lysosomes and Use Protein as a Nutrient] [Re: Nutrient sensor in key growth-regulating metabolic pathway identified [Lysosomal amino acid transporter SLC38A9 signals arginine sufficiency to mTORC1]]                              

Solution 2.*

Per How can I replace a newline (\n) using sed?

sed ':a;N;$!ba;s/\n/ /g' corpus/01

will replace newlines with a space.

Chaining that with A2 in How to use sed/grep to extract text between two words?, we get:

sed ':a;N;$!ba;s/\n/ /g' corpus/01 | grep -o -P '(?<=Subject: ).*(?=Message-ID:)'

which gives

[SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key molecular  link in major cell growth pathway: Findings point to new potential  therapeutic target in pancreatic cancer [mTORC1 Activator SLC38A9 Is  Required to Efflux Essential Amino Acids from Lysosomes and Use Protein as  a Nutrient] [Re: Nutrient sensor in key growth-regulating metabolic pathway  identified [Lysosomal amino acid transporter SLC38A9 signals arginine  sufficiency to mTORC1]] 

This variant removes double spaces:

sed ':a;N;$!ba;s/\n/ /g; s/\s\s*/ /g' corpus/01 | grep -o -P '(?<=Subject: ).*(?=Message-ID:)'

giving

[SLC38A9 lysosomal arginine sensor; mTORC1 pathway] Key molecular link in major cell growth pathway: Findings point to new potential therapeutic target in pancreatic cancer [mTORC1 Activator SLC38A9 Is Required to Efflux Essential Amino Acids from Lysosomes and Use Protein as a Nutrient] [Re: Nutrient sensor in key growth-regulating metabolic pathway identified [Lysosomal amino acid transporter SLC38A9 signals arginine sufficiency to mTORC1]]

If you don't like libraries, how about this?

Note that you should not use this function on the whole URL, instead you should use this on the components...e.g. just the "a b" component, as you build up the URL - otherwise the computer won't know what characters are supposed to have a special meaning and which ones are supposed to have a literal meaning.

/** Converts a string into something you can safely insert into a URL. */
public static String encodeURIcomponent(String s)
{
    StringBuilder o = new StringBuilder();
    for (char ch : s.toCharArray()) {
        if (isUnsafe(ch)) {
            o.append('%');
            o.append(toHex(ch / 16));
            o.append(toHex(ch % 16));
        }
        else o.append(ch);
    }
    return o.toString();
}

private static char toHex(int ch)
{
    return (char)(ch < 10 ? '0' + ch : 'A' + ch - 10);
}

private static boolean isUnsafe(char ch)
{
    if (ch > 128 || ch < 0)
        return true;
    return " %$&+,/:;=?@<>#%".indexOf(ch) >= 0;

In C# this is how to get the resolution Screen:

button click or form load:

string screenWidth = Screen.PrimaryScreen.Bounds.Width.ToString();
string screenHeight = Screen.PrimaryScreen.Bounds.Height.ToString();
Label1.Text = ("Resolution: " + screenWidth + "x" + screenHeight);

Look closely at your code. In it, there are already three line breaks, and a ton of white space before </textarea>. Remove those first so that there are no line breaks in between the tags any more. It might already do the trick.

Also you can use ss utility to dump sockets statistics.

To dump summary:

ss -s

Total: 91 (kernel 0)
TCP:   18 (estab 11, closed 0, orphaned 0, synrecv 0, timewait 0/0), ports 0

Transport Total     IP        IPv6
*         0         -         -        
RAW       0         0         0        
UDP       4         2         2        
TCP       18        16        2        
INET      22        18        4        
FRAG      0         0         0

To display all sockets:

ss -a

To display UDP sockets:

ss -u -a

To display TCP sockets:

ss -t -a

Here you can read ss man: ss

In larvel => 6 Version:

Input no longer exists In larvel 6,7,8 Version. Use Request instead of Input.

Based on the Laravel docs, since version 6.x Input has been removed.

The Input Facade

Likelihood Of Impact: Medium

The Input facade, which was primarily a duplicate of the Request facade, has been removed. If you are using the Input::get method, you should now call the Request::input method. All other calls to the Input facade may simply be updated to use the Request facade.

use Illuminate\Support\Facades\Request;
..
..
..
 public function functionName(Request $request)
    {
        $searchInput = $request->q;
}

If you are not given a specific file and you need to extract IP address then we need to do it recursively. grep command -> Searches a text or file for matching a given string and displays the matched string .

grep -roE '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}' | grep -oE '[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}'

-r We can search the entire directory tree i.e. the current directory and all levels of sub-directories. It denotes recursive searching.

-o Print only the matching string

-E Use extended regular expression

If we would not have used the second grep command after the pipe we would have got the IP address along with the path where it is present

The new urllib3 library has a nice documentation here
In order to get your desired result you shuld follow that:

Import urllib3
from bs4 import BeautifulSoup

url = 'http://www.thefamouspeople.com/singers.php'

http = urllib3.PoolManager()
response = http.request('GET', url)
soup = BeautifulSoup(response.data.decode('utf-8'))

The "decode utf-8" part is optional. It worked without it when i tried, but i posted the option anyway.

This solved the issue for me:

pip install -I --upgrade psutil --force

Afterwards just uninstall psutil with the new version and hop you can suddenly install the older version (:

I could be wrong but I thought it used IE's proxy settings.

If it sees that you need to login it opens a dialog and asks you to do so (login that is).

You can use CSS for that.

HTML (only for demo, it is customizable)

<div class="button">
    <input type="radio" name="a" value="a" id="a" />
    <label for="a">a</label>
</div>
<div class="button">
    <input type="radio" name="a" value="b" id="b" />
    <label for="b">b</label>
</div>
<div class="button">
    <input type="radio" name="a" value="c" id="c" />
    <label for="c">c</label>
</div>
...

CSS

input[type="radio"] {
    display: none;
}
input[type="radio"]:checked + label {
    border: 1px solid red;
}

My solution is:

$maxs = array_keys($array, max($array))

Note:
this way you can retrieve every key related to a given max value.

If you are interested only in one key among all simply use $maxs[0]

Steps to change the default date format of ng-model

For different date formats check the jqueryui datepicker date format values here for example I have used dd/mm/yy

Create angularjs directive

angular.module('app', ['ui.bootstrap']).directive('dt', function () {
return {
    restrict: 'EAC',
    require: 'ngModel',
    link: function (scope, element, attr, ngModel) {
        ngModel.$parsers.push(function (viewValue) {
           return dateFilter(viewValue, 'dd/mm/yy');
        });
    }
 }
});

Write dateFilter function

function dateFilter(val,format) {
    return $.datepicker.formatDate(format,val);
}

In html page write the ng-modal attribute

<input type="text" class="form-control" date-type="string"  uib-datepicker-popup="{{format}}" ng-model="src.pTO_DATE" is-open="popup2.opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" show-button-bar="false" show-weeks="false" dt />

The GroupBox has a Validated event for this purpose, if you are using WinForms.

private void grpBox_Validated(object sender, EventArgs e)
    {
        GroupBox g = sender as GroupBox;
        var a = from RadioButton r in g.Controls
                 where r.Checked == true select r.Name;
        strChecked = a.First();
     }

A Comma Separated File is really just a text file where the lines consist of values separated by commas.

There is no standard which defines the contents of a CSV file, so there is no defined way of indicating a comment. It depends on the program which will be importing the CSV file.

Of course, this is usually Excel. You should ask yourself how does Excel define a comment? In other words, what would make Excel ignore a line (or part of a line) in the CSV file? I'm not aware of anything which would do this.

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.

How about:

echo "hello" >> <filename>

Using the >> operator will append data at the end of the file, while using the > will overwrite the contents of the file if already existing.

You could also use printf in the same way:

printf "hello" >> <filename>

Note that it can be dangerous to use the above. For instance if you already have a file and you need to append data to the end of the file and you forget to add the last > all data in the file will be destroyed. You can change this behavior by setting the noclobber variable in your .bashrc:

set -o noclobber

Now when you try to do echo "hello" > file.txt you will get a warning saying cannot overwrite existing file.

To force writing to the file you must now use the special syntax:

echo "hello" >| <filename>

You should also know that by default echo adds a trailing new-line character which can be suppressed by using the -n flag:

echo -n "hello" >> <filename>

References

• echo(1) - Linux man page
• noclobber variable
• I/O Redirection

isinstance works:

if isinstance(obj, MyClass): do_foo(obj)

but, keep in mind: if it looks like a duck, and if it sounds like a duck, it is a duck.

EDIT: For the None type, you can simply do:

if obj is None: obj = MyClass()

In version 7.1.2 pip downloads the wheel of a package (if available) with the following:

pip install package -d /path/to/downloaded/file

The following downloads a source distribution:

pip install package -d /path/to/downloaded/file --no-binary :all:

These download the dependencies as well, if pip is aware of them (e.g., if pip show package lists them).

Update

As noted by Anton Khodak, pip download command is preferred since version 8. In the above examples this means that /path/to/downloaded/file needs to be given with option -d, so replacing install with download works.

You just need to:

Step 1: Go home directory of C:\ with typing cd.. (2 times)

Step 2: It appears now C:\>

Step 3: Type dir Windows\System32\run

That's all, it shows complete files & folder details inside target folder.

Details: I used Windows\System32\com folder as example, you should type your own folder name etc. Windows\System32\run

You are getting AttributeError because you're calling groups on None, which hasn't any methods.

regex.search returning None means the regex couldn't find anything matching the pattern from supplied string.

when using regex, it is nice to check whether a match has been made:

Result = re.search(SearchStr, htmlString)

if Result:
    print Result.groups()

Update: Two lightweight CSS solutions:

Using flex, flex-flow and order:

Example1: Demo Fiddle

    body{
        display:flex;
        flex-flow: column;
    }
    #blockA{
        order:4;
    }
    #blockB{
        order:3;
    }
    #blockC{
        order:2;
    }

Alternatively, reverse the Y scale:

Example2: Demo Fiddle

body{
    -webkit-transform: scaleY(-1);
    transform: scaleY(-1);
}
div{
    -webkit-transform: scaleY(-1);
    transform: scaleY(-1);
}

Try the following

for ( const auto &p : table )
{
   std::cout << p.first << '\t' << p.second << std::endl;
} 

The same can be written using an ordinary for loop

for ( auto it = table.begin(); it != table.end(); ++it  )
{
   std::cout << it->first << '\t' << it->second << std::endl;
} 

Take into account that value_type for std::map is defined the following way

typedef pair<const Key, T> value_type

Thus in my example p is a const reference to the value_type where Key is std::string and T is int

Also it would be better if the function would be declared as

void output( const map<string, int> &table );

The best way around this would be to create an Excel called 'launcher.xlsm' in the same folder as the file you wish to open. In the 'launcher' file put the following code in the 'Workbook' object, but set the constant TargetWBName to be the name of the file you wish to open.

Private Const TargetWBName As String = "myworkbook.xlsx"

'// First, a function to tell us if the workbook is already open...
Function WorkbookOpen(WorkBookName As String) As Boolean
' returns TRUE if the workbook is open
    WorkbookOpen = False
    On Error GoTo WorkBookNotOpen
    If Len(Application.Workbooks(WorkBookName).Name) > 0 Then
        WorkbookOpen = True
        Exit Function
    End If
WorkBookNotOpen:
End Function

Private Sub Workbook_Open()
    'Check if our target workbook is open
    If WorkbookOpen(TargetWBName) = False Then
        'set calculation to manual
        Application.Calculation = xlCalculationManual
        Workbooks.Open ThisWorkbook.Path & "\" & TargetWBName
        DoEvents
        Me.Close False
    End If
End Sub

Set the constant 'TargetWBName' to be the name of the workbook that you wish to open. This code will simply switch calculation to manual, then open the file. The launcher file will then automatically close itself. *NOTE: If you do not wish to be prompted to 'Enable Content' every time you open this file (depending on your security settings) you should temporarily remove the 'me.close' to prevent it from closing itself, save the file and set it to be trusted, and then re-enable the 'me.close' call before saving again. Alternatively, you could just set the False to True after Me.Close

Any chance that you changed the name of your table view from "tableView" to "myTableView" at some point?

The regex module recommended in python docs, supports this

words = {'he', 'or', 'low'}
p = regex.compile(r"\L<name>", name=words)
m = p.findall('helloworld')
print(m)

output:

['he', 'low', 'or']

Some details on implementation: link

The above answer doesn't support observable interpolation (and cost me a lot of time trying to debug). The jsFiddle link in @BrandonTilley comment was the answer that worked for me, which I'll re-post here for preservation:

app.directive('backImg', function(){
    return function(scope, element, attrs){
        attrs.$observe('backImg', function(value) {
            element.css({
                'background-image': 'url(' + value +')',
                'background-size' : 'cover'
            });
        });
    };
});

Example using controller and template

Controller :

$scope.someID = ...;
/* 
The advantage of using directive will also work inside an ng-repeat :
someID can be inside an array of ID's 
*/

$scope.arrayOfIDs = [0,1,2,3];

Template :

Use in template like so :

<div back-img="img/service-sliders/{{someID}}/1.jpg"></div>

or like so :

<div ng-repeat="someID in arrayOfIDs" back-img="img/service-sliders/{{someID}}/1.jpg"></div>

#!/usr/bin/python3 is a shebang line.

A shebang line defines where the interpreter is located. In this case, the python3 interpreter is located in /usr/bin/python3. A shebang line could also be a bash, ruby, perl or any other scripting languages' interpreter, for example: #!/bin/bash.

Without the shebang line, the operating system does not know it's a python script, even if you set the execution flag (chmod +x script.py) on the script and run it like ./script.py. To make the script run by default in python3, either invoke it as python3 script.py or set the shebang line.

You can use #!/usr/bin/env python3 for portability across different systems in case they have the language interpreter installed in different locations.

//file1.php
<?php

class ClassA
{
   private $name = 'John';

   function getName()
   {
     return $this->name;
   }   
}
?>

//file2.php
<?php
   include ("file1.php");

   class ClassB
   {

     function __construct()
     {
     }

     function callA()
     {
       $classA = new ClassA();
       $name = $classA->getName();
       echo $name;    //Prints John
     }
   }

   $classb = new ClassB();
   $classb->callA();
?>

I'd refrain from using floats for this sort of thing; I'd rather use inline-block.

Some more points to consider:

• Inline styles are bad for maintainability
• You shouldn't have spaces in selector names
• You missed some important HTML tags, like <head> and <body>
• You didn't include a doctype

Here's a better way to format your document:

<!DOCTYPE html>
<html>
<head>
<title>Website Title</title>
<style type="text/css">
* {margin: 0; padding: 0;}
#container {height: 100%; width:100%; font-size: 0;}
#left, #middle, #right {display: inline-block; *display: inline; zoom: 1; vertical-align: top; font-size: 12px;}
#left {width: 25%; background: blue;}
#middle {width: 50%; background: green;}
#right {width: 25%; background: yellow;}
</style>
</head>
<body>
<div id="container">
    <div id="left">Left Side Menu</div>
    <div id="middle">Random Content</div>
    <div id="right">Right Side Menu</div>
</div>
</body>
</html>

Here's a jsFiddle for good measure.

dynDiv.Attributes["class"] = "myCssClass";

I spent a day messing with CSS before I found anataliocs tip. Add wmode=transparent as a parameter to the YouTube URL:

<iframe title=<your frame title goes here> 
    src="http://www.youtube.com/embed/K3j9taoTd0E?wmode=transparent"  
    scrolling="no" 
    frameborder="0" 
    width="640" 
    height="390" 
    style="border:none;">
</iframe>

This allows the iframe to inherit the z-index of its container so your opaque <div> would be in front of the iframe.

My rep is too low to comment, but concerning the CallbackOnCollectedDelegate exception, I modified the public void SetupKeyboardHooks() in C4d's answer to look like this:

public void SetupKeyboardHooks(out object hookProc)
{
  _globalKeyboardHook = new GlobalKeyboardHook();
  _globalKeyboardHook.KeyboardPressed += OnKeyPressed;


  hookProc = _globalKeyboardHook.GcSafeHookProc;
}

where GcSafeHookProc is just a public getter for _hookProc in OPs

_hookProc = LowLevelKeyboardProc; // we must keep alive _hookProc, because GC is not aware about SetWindowsHookEx behaviour.

and stored the hookProc as a private field in the class calling the SetupKeyboardHooks(...), therefore keeping the reference alive, save from garbage collection, no more CallbackOnCollectedDelegate exception. Seems having this additional reference in the GlobalKeyboardHook class is not sufficient. Maybe make sure that this reference is also disposed when closing your app.

I can see libc error in the log.

install these packages in your system

sudo apt-get install lib32stdc++6 lib32z1 lib32z1-dev

Restart android studio after installation

I know if that can help you a bit.

Here is something I tried to simulate for you.

Checkout the jsFiddle ;)

http://jsfiddle.net/migontech/gbW8Z/5/

Created a filter that you also can use in 'ng-repeat'

app.filter('getById', function() {
  return function(input, id) {
    var i=0, len=input.length;
    for (; i<len; i++) {
      if (+input[i].id == +id) {
        return input[i];
      }
    }
    return null;
  }
});

Usage in controller:

app.controller('SomeController', ['$scope', '$filter', function($scope, $filter) {
     $scope.fish = [{category:'freshwater', id:'1', name: 'trout', more:'false'},  {category:'freshwater', id:'2', name:'bass', more:'false'}]

     $scope.showdetails = function(fish_id){
         var found = $filter('getById')($scope.fish, fish_id);
         console.log(found);
         $scope.selected = JSON.stringify(found);
     }
}]);

If there are any questions just let me know.

Since Jet 4, all queries that have a join to a SQL statement that summarizes data will be non-updatable. You aren't using a JOIN, but the WHERE clause is exactly equivalent to a join, and thus, the Jet query optimizer treats it the same way it treats a join.

I'm afraid you're out of luck without a temp table, though maybe somebody with greater Jet SQL knowledge than I can come up with a workaround.

BTW, it might have been updatable in Jet 3.5 (Access 97), as a whole lot of queries were updatable then that became non-updatable when upgraded to Jet 4.

The way I think of it is Debug.Assert is a way to establish a contract about how a method is supposed to be called, focusing on specifics about the values of a paramter (instead of just the type). For example, if you are not supposed to send a null in the second parameter you add the Assert around that parameter to tell the consumer not to do that.

It prevents someone from using your code in a boneheaded way. But it also allows that boneheaded way to go through to production and not give the nasty message to a customer (assuming you build a Release build).

The new version of phpMyAdmin (3.5.1) has much better support for stored procedures; including: editing, execution, exporting, PHP code creation, and some debugging.

Open any database, you'll see a new tab at the top called Routines, then select Add Routine.

The first test I did produced the following error message:

Ciuly's Blog provides a good solution, assuming you have command line access. Not sure how you would fix it if you don't.

May be using two br tags is the simplest solution that works with all browsers. But it is repetitive.

The swift 4.2 version of solution would be the following:

let spacing: CGFloat = 10 // the amount of spacing to appear between image and title
self.button?.imageEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: spacing)
self.button?.titleEdgeInsets = UIEdgeInsets(top: 0, left: spacing, bottom: 0, right: 0)

Are you asking about absolute values?

Math.abs(...) is the function you probably want.

To use foreach would require you have an array that contains every row from the query result. Some DB libraries for PHP provide a fetch_all function that provides an appropriate array but I could not find one for mysql (however the mysqli extension does) . You could of course write your own, like so

function mysql_fetch_all($result) {
   $rows = array();
   while ($row = mysql_fetch_array($result)) {
     $rows[] = $row;
   }
   return $rows;
}

However I must echo the "why?" Using this function you are creating two loops instead of one, and requring the entire result set be loaded in to memory. For sufficiently large result sets, this could become a serious performance drag. And for what?

foreach (mysql_fetch_all($result) as $row)

vs

while ($row = mysql_fetch_array($result))

while is just as concise and IMO more readable.

EDIT There is another option, but it is pretty absurd. You could use the Iterator Interface

class MysqlResult implements Iterator {
  private $rownum = 0;
  private $numrows = 0;
  private $result;

  public function __construct($result) {
    $this->result = $result;
    $this->numrows = mysql_num_rows($result);
  }

  public function rewind() {
    $this->rownum = 0;
  }

  public function current() {
    mysql_data_seek($this->result, $this->rownum);
    return mysql_fetch_array($this->result);
  }

  public function key() {
    return $this->rownum;
  }

  public function next() {
    $this->rownum++;
  }

  public function valid() {
    return $this->rownum < $this->numrows ? true : false;
  }
}

$rows = new MysqlResult(mysql_query($query_select));

foreach ($rows as $row) {
  //code...
}

In this case, the MysqlResult instance fetches rows only on request just like with while, but wraps it in a nice foreach-able package. While you've saved yourself a loop, you've added the overhead of class instantiation and a boat load of function calls, not to mention a good deal of added code complexity.

But you asked if it could be done without using while (or for I imagine). Well it can be done, just like that. Whether it should be done is up to you.

Shorter than accepted A, easily extensible and addresses 0 and below:

=if(or(A2<=0,A2>2000),"?",if(A2<500,"Less than 500","Between "&500*int(A2/500)&" and "&500*(int(A2/500)+1))) 

You could always use a list comprehension and check the results with all, it would be a little less resource intensive than using a regex: all([c in string.letters + string.digits + ["_", "-"] for c in mystring])

In the old days, when we could assume that most computers used ASCII, we would just do

int i = c[0] - '0';

But in these days of Unicode, it's not a good idea. It was never a good idea if your code had to run on a non-ASCII computer.

Edit: Although it looks hackish, evidently it is guaranteed by the standard to work. Thanks @Earwicker.

The first thing you need is the real File path If you have it great, if you are using URI then use this method to get the real Path:

 public static String getRealPathFromURI(Uri contentURI,Context context) {
    String path= contentURI.getPath();
    try {
        Cursor cursor = context.getContentResolver().query(contentURI, null, null, null, null);
        cursor.moveToFirst();
        String document_id = cursor.getString(0);
        document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
        cursor.close();

        cursor = context.getContentResolver().query(
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
        cursor.moveToFirst();
        path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
        cursor.close();
    }
    catch(Exception e)
    {
        return path;
    }
    return path;
}

extract your Bitmap for example:

  try {
                            Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);

                        }
                        catch (IOException e)
                        {
                            Log.e("IOException",e.toString());
                        }

you can use decodeFile() instead if you wish.

Now that you have the Bitmap and the real Path get the Orientation of the Image:

 private static int getExifOrientation(String src) throws IOException {
        int orientation = 1;

        ExifInterface exif = new ExifInterface(src);
        String orientationString=exif.getAttribute(ExifInterface.TAG_ORIENTATION);
        try {
            orientation = Integer.parseInt(orientationString);
        }
        catch(NumberFormatException e){}

        return orientation;
    }

and finally rotate it to the right position like so:

public static Bitmap rotateBitmap(String src, Bitmap bitmap) {
        try {
            int orientation = getExifOrientation(src);

            if (orientation == 1) {
                return bitmap;
            }

            Matrix matrix = new Matrix();
            switch (orientation) {
                case 2:
                    matrix.setScale(-1, 1);
                    break;
                case 3:
                    matrix.setRotate(180);
                    break;
                case 4:
                    matrix.setRotate(180);
                    matrix.postScale(-1, 1);
                    break;
                case 5:
                    matrix.setRotate(90);
                    matrix.postScale(-1, 1);
                    break;
                case 6:
                    matrix.setRotate(90);
                    break;
                case 7:
                    matrix.setRotate(-90);
                    matrix.postScale(-1, 1);
                    break;
                case 8:
                    matrix.setRotate(-90);
                    break;
                default:
                    return bitmap;
            }

            try {
                Bitmap oriented = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
                bitmap.recycle();
                return oriented;
            } catch (OutOfMemoryError e) {
                e.printStackTrace();
                return bitmap;
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        return bitmap;
    }

That's it , you now have the bitmap rotated to the right position.

cheers.

Note that if the object you are talking about has a custom property model (such as DataRowView etc for DataTable), then you need to use TypeDescriptor; the good news is that this still works fine for regular classes (and can even be much quicker than reflection):

foreach(PropertyDescriptor prop in TypeDescriptor.GetProperties(obj)) {
    Console.WriteLine("{0} = {1}", prop.Name, prop.GetValue(obj));
}

This also provides easy access to things like TypeConverter for formatting:

    string fmt = prop.Converter.ConvertToString(prop.GetValue(obj));

To add the solution I found to this problem when I had it, I was including a class from another file and the file I tried to instantiate it in gave the "not a constructor" error. Ultimately the issue was a couple unused requires in the other file before the class was defined. I'm not sure why they broke it, but removing them fixed it. Always be sure to check if something might be hiding in between the steps you're thinking about.

This issue arise because we try to delete the parent table still child table data is present. We solve the problem with help of cascade delete.

In model Create method in dbcontext class.

 modelBuilder.Entity<Job>()
                .HasMany<JobSportsMapping>(C => C.JobSportsMappings)
                .WithRequired(C => C.Job)
                .HasForeignKey(C => C.JobId).WillCascadeOnDelete(true);
            modelBuilder.Entity<Sport>()
                .HasMany<JobSportsMapping>(C => C.JobSportsMappings)
                  .WithRequired(C => C.Sport)
                  .HasForeignKey(C => C.SportId).WillCascadeOnDelete(true);

After that,In our API Call

var JobList = Context.Job                       
          .Include(x => x.JobSportsMappings)                                     .ToList();
Context.Job.RemoveRange(JobList);
Context.SaveChanges();

Cascade delete option delete the parent as well parent related child table with this simple code. Make it try in this simple way.

Remove Range which used for delete the list of records in the database Thanks

Based on kynan's answer, here are the same aliases, modified so they can handle spaces and initial dashes in filenames:

accept-ours = "!f() { [ -z \"$@\" ] && set - '.'; git checkout --ours -- \"$@\"; git add -u -- \"$@\"; }; f"
accept-theirs = "!f() { [ -z \"$@\" ] && set - '.'; git checkout --theirs -- \"$@\"; git add -u -- \"$@\"; }; f"

For anyone trying to mirror the Back button style with the chevron like this:

import UIKit

class NextBarButton: UIBarButtonItem {

    convenience init(target: Any, selector: Selector) {

        // Create UIButton
        let button = UIButton(frame: .zero)

        // Set Title
        button.setTitle("Next", for: .normal)
        button.setTitleColor(.systemBlue, for: .normal)
        button.titleLabel?.font = UIFont.systemFont(ofSize: 17)

        // Configure Symbol
        let config = UIImage.SymbolConfiguration(pointSize: 19.0, weight: .semibold, scale: .large)
        let image = UIImage(systemName: "chevron.right", withConfiguration: config)
        button.setImage(image, for: .normal)

        // Add Target
        button.addTarget(target, action: selector, for: .touchUpInside)

        // Put the Image on the right hand side of the button
        // Credit to liau-jian-jie for this part
        button.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
        button.titleLabel?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
        button.imageView?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)

        // Customise spacing to match system Back button
        button.imageEdgeInsets = UIEdgeInsets(top: 0.0, left: -18.0, bottom: 0.0, right: 0.0)
        button.titleEdgeInsets = UIEdgeInsets(top: 0.0, left: -12.0, bottom: 0.0, right: 0.0)

        self.init(customView: button)
    }
}

Implementation:

override func viewDidLoad() {
    super.viewDidLoad()
    let nextButton = NextBarButton(target: self, selector: #selector(nextTapped))
    navigationItem.rightBarButtonItem = nextButton
}

@objc func nextTapped() {
    // your code
}

Here is a simple programe to capture a image from using laptop default camera.I hope that this will be very easy method for all.

import cv2

# 1.creating a video object
video = cv2.VideoCapture(0) 
# 2. Variable
a = 0
# 3. While loop
while True:
    a = a + 1
    # 4.Create a frame object
    check, frame = video.read()
    # Converting to grayscale
    #gray = cv2.cvtColor(frame,cv2.COLOR_BGR2GRAY)
    # 5.show the frame!
    cv2.imshow("Capturing",frame)
    # 6.for playing 
    key = cv2.waitKey(1)
    if key == ord('q'):
        break
# 7. image saving
showPic = cv2.imwrite("filename.jpg",frame)
print(showPic)
# 8. shutdown the camera
video.release()
cv2.destroyAllWindows

[Linqer] is a SQL to LINQ converter tool. It helps you to learn LINQ and convert your existing SQL statements.

Not every SQL statement can be converted to LINQ, but Linqer covers many different types of SQL expressions. Linqer supports both .NET languages - C# and Visual Basic.

All the random numbers generated after setting particular seed value are same across all the platforms/systems.

this works for me, sudo apt-get install libx11-dev

I had to manage a scenario where the percentage of duplicates being provided in the new data records was very high, and so many thousands of database calls were being made to check for duplicates (so the CPU sent a lot of time at 100%). In the end I decided to keep the last 100,000 records cached in memory. This way I could check for duplicates against the cached records which was extremely fast when compared to a LINQ query against the SQL database, and then write any genuinely new records to the database (as well as add them to the data cache, which I also sorted and trimmed to keep its length manageable).

Note that the raw data was a CSV file that contained many individual records that had to be parsed. The records in each consecutive file (which came at a rate of about 1 every 5 minutes) overlapped considerably, hence the high percentage of duplicates.

In short, if you have timestamped raw data coming in, pretty much in order, then using a memory cache might help with the record duplication check.

tar.gz file is just a tar file that's been gzipped. Both tar and gzip are available for windows.

If you like GUIs (Graphical user interface), 7zip can pack with both tar and gzip.

Here is a log lifecycle of each fragment in ViewPager which have 4 fragment and offscreenPageLimit = 1 (default value)

FragmentStatePagerAdapter

Go to Fragment1 (launch activity)

Fragment1: onCreateView
Fragment1: onStart
Fragment2: onCreateView
Fragment2: onStart

Go to Fragment2

Fragment3: onCreateView
Fragment3: onStart

Go to Fragment3

Fragment1: onStop
Fragment1: onDestroyView
Fragment1: onDestroy
Fragment1: onDetach
Fragment4: onCreateView
Fragment4: onStart

Go to Fragment4

Fragment2: onStop
Fragment2: onDestroyView
Fragment2: onDestroy

FragmentPagerAdapter

Go to Fragment1 (launch activity)

Fragment1: onCreateView
Fragment1: onStart
Fragment2: onCreateView
Fragment2: onStart

Go to Fragment2

Fragment3: onCreateView
Fragment3: onStart

Go to Fragment3

Fragment1: onStop
Fragment1: onDestroyView
Fragment4: onCreateView
Fragment4: onStart

Go to Fragment4

Fragment2: onStop
Fragment2: onDestroyView

Conclusion: FragmentStatePagerAdapter call onDestroy when the Fragment is overcome offscreenPageLimit while FragmentPagerAdapter not.

Note: I think we should use FragmentStatePagerAdapter for a ViewPager which have a lot of page because it will good for performance.

Example of offscreenPageLimit:

If we go to Fragment3, it will detroy Fragment1 (or Fragment5 if have) because offscreenPageLimit = 1. If we set offscreenPageLimit > 1 it will not destroy.
If in this example, we set offscreenPageLimit=4, there is no different between using FragmentStatePagerAdapter or FragmentPagerAdapter because Fragment never call onDestroyView and onDestroy when we change tab

Your problem is on the call for the dialog

If you dont initialize the dialog, you don't have to pass "open" for it to show:

$("#dialog").dialog();

Also, this code needs to be on a $(document).ready(); function or be below the elements for it to work.

Inline elements:

1. respect left & right margins and padding, but not top & bottom
2. cannot have a width and height set
3. allow other elements to sit to their left and right.
4. see very important side notes on this here.

Block elements:

1. respect all of those
2. force a line break after the block element
3. acquires full-width if width not defined

Inline-block elements:

1. allow other elements to sit to their left and right
2. respect top & bottom margins and padding
3. respect height and width

From W3Schools:

• An inline element has no line break before or after it, and it tolerates HTML elements next to it.

• A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.

• An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

When you visualize this, it looks like this:

The image is taken from this page, which also talks some more about this subject.

The Value of num will be some garbage value from the main memory(RAM). its better if you initialize the variable just after creating.

You can simply set the status code of the response to 200 like the following

public ActionResult SomeMethod(parameters...)
{
   //others code here
   ...      
   Response.StatusCode = 200;
   return YourObject;  
}

All About margins

this works in Android, but did not test it in ios

import React, { PureComponent } from 'react'
import PropTypes from 'prop-types'
import { View, Platform } from 'react-native'
import EStyleSheet from 'react-native-extended-stylesheet'

const styles = EStyleSheet.create({
    wrapper: {
        margin: '-1.4rem'
    },
    shadow: {
        padding: '1.4rem',
        margin: '1.4rem',
        borderRadius: 4,
        borderWidth: 0,
        borderColor: 'transparent',
        ...Platform.select({
            ios: {
                shadowColor: 'rgba(0,0,0, 0.4)',
                shadowOffset: { height: 1, width: 1 },
                shadowOpacity: 0.7,
                shadowRadius: '1.4rem'
            },
            android: {
                elevation: '1.4rem'
            }
        })
    },

class ShadowWrapper extends PureComponent {
    static propTypes = {
        children: PropTypes.oneOfType([
            PropTypes.element,
            PropTypes.node,

    }
}

export default ShadowWrapper

{{ app.user.username|default('') }}

Just present login username for example, filter function default('') should be nice when user is NOT login by just avoid annoying error message.

According to the documentation, there needs to be a top level layout set.

A top level layout is necessary to ensure that your widgets will resize correctly when its window is resized. To check if you have set a top level layout, preview your widget and attempt to resize the window by dragging the size grip.

You can set one by clearing the selection and right clicking on the form itself and choosing one of the layouts available in the context menu.

For me, this error message originated from a banner from Admob SDK.

I was able to track the origin to "WebThread" by setting a conditional breakpoint.

Then I was able to get rid of the issue by encapsulating the Banner creation with:

dispatch_async(dispatch_get_main_queue(), ^{
   _bannerForTableFooter = [[GADBannerView alloc] initWithAdSize:kGADAdSizeSmartBannerPortrait];
   ...
}

I don't know why this helped as I cannot see how this code was called from a non-main-thread.

Hope it can help anyone.

<?php echo 'apple'; ?> is pretty much literally all you need on the server.

as for the JS side, the output of the server-side script is passed as a parameter to the success handler function, so you'd have

success: function(data) {
   alert(data); // apple
}

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

[[ $1 =~ ^-?[0-9]+$ ]] && echo "number"

Don't forget - to include negative numbers!

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

The context parameter just sets the value of this in the iterator function.

var someOtherArray = ["name","patrick","d","w"];

_.each([1, 2, 3], function(num) { 
    // In here, "this" refers to the same Array as "someOtherArray"

    alert( this[num] ); // num is the value from the array being iterated
                        //    so this[num] gets the item at the "num" index of
                        //    someOtherArray.
}, someOtherArray);

Working Example: http://jsfiddle.net/a6Rx4/

It uses the number from each member of the Array being iterated to get the item at that index of someOtherArray, which is represented by this since we passed it as the context parameter.

If you do not set the context, then this will refer to the window object.

// import following package
import scala.util.control._

// create a Breaks object as follows
val loop = new Breaks;

// Keep the loop inside breakable as follows
loop.breakable{
// Loop will go here
for(...){
   ....
   // Break will go here
   loop.break;

If you use the Logcat display inside the 'debug' perspective in Eclipse the lines are colour-coded. It's pretty easy to find what made your app crash because it's usually in red.

The Java (or Dalvik) virtual machine should never crash, but if your program throws an exception and does not catch it the VM will terminate your program, which is the 'crash' you are seeing.

In my projects, this piece of code always worked as a default serializer which serializes the specified value as if there was no special converter:

serializer.Serialize(writer, value);

s=[52, 33, 70, 39, 57, 59, 7, 2, 46, 69, 11, 74, 58, 60, 63, 43, 75, 92, 65, 19, 1, 79, 22, 38, 26, 3, 66, 88, 9, 15, 28, 44, 67, 87, 21, 49, 85, 32, 89, 77, 47, 93, 35, 12, 73, 76, 50, 45, 5, 29, 97, 94, 95, 56, 48, 71, 54, 55, 51, 23, 84, 80, 62, 30, 13, 34]

dic={}

for i in range(0,len(s),10):
    dic[i,i+10]=list(filter(lambda x:((x>=i)&(x<i+10)),s))
print(dic)

for keys,values in dic.items():
    print(keys)
    print(values)

Output:

(0, 10)
[7, 2, 1, 3, 9, 5]
(20, 30)
[22, 26, 28, 21, 29, 23]
(30, 40)
[33, 39, 38, 32, 35, 30, 34]
(10, 20)
[11, 19, 15, 12, 13]
(40, 50)
[46, 43, 44, 49, 47, 45, 48]
(60, 70)
[69, 60, 63, 65, 66, 67, 62]
(50, 60)
[52, 57, 59, 58, 50, 56, 54, 55, 51]  

For me:

$last = $array[count($array) - 1];

With associatives:

$last =array_values($array)[count($array - 1)]

To print subprocess' output line-by-line as soon as its stdout buffer is flushed in Python 3:

from subprocess import Popen, PIPE, CalledProcessError

with Popen(cmd, stdout=PIPE, bufsize=1, universal_newlines=True) as p:
    for line in p.stdout:
        print(line, end='') # process line here

if p.returncode != 0:
    raise CalledProcessError(p.returncode, p.args)

Notice: you do not need p.poll() -- the loop ends when eof is reached. And you do not need iter(p.stdout.readline, '') -- the read-ahead bug is fixed in Python 3.

See also, Python: read streaming input from subprocess.communicate().

In order to get the group chat id, do as follows:

1. Add the Telegram BOT to the group.

2. Get the list of updates for your BOT:

   https://api.telegram.org/bot<YourBOTToken>/getUpdates
   

   Ex:

   https://api.telegram.org/bot123456789:jbd78sadvbdy63d37gda37bd8/getUpdates
   

3. Look for the "chat" object:

{"update_id":8393,"message":{"message_id":3,"from":{"id":7474,"first_name":"AAA"},"chat":{"id":,"title":""},"date":25497,"new_chat_participant":{"id":71,"first_name":"NAME","username":"YOUR_BOT_NAME"}}}

This is a sample of the response when you add your BOT into a group.

4. Use the "id" of the "chat" object to send your messages.

In Some cases, you need to increase the maximum execution time.

max_execution_time=30

I made it

max_execution_time=600000

then I was happy.

var iDiv = document.createElement('div'),
    jDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';
jDiv.className = 'block-2';
iDiv.appendChild(jDiv);
document.getElementsByTagName('body')[0].appendChild(iDiv);

Why don't you build a DataTable first then assign it to the DataGridView as DataSource:

DataTable table4DataSource=new DataTable();

table4DataSource.Columns.Add("col00");
table4DataSource.Columns.Add("col01");
table4DataSource.Columns.Add("col02");

...

(add your rows, manually, in a circle or via a DataReader from a database table) (assign the datasource)

dtGrdViewGrid.DataSource = table4DataSource;

and then use:

(dtGrdViewGrid.DataSource as DataTable).DefaultView.RowFilter = "col00 = '" + textBoxSearch.Text+ "'";
dtGrdViewGrid.Refresh();

You can even put this piece of code within your textbox_textchange event and your filtered values will be showing as you write.

By omitting all parts of the head, the loop can also become infinite:

for (;;) {}

Assuming you're asking for WinForms, you may use the FormClosing() event. The event FormClosing() is triggered any time a form is to get closed.

To detect if the user clicked either X or your CloseButton, you may get it through the sender object. Try to cast sender as a Button control, and verify perhaps for its name "CloseButton", for instance.

private void Form1_FormClosing(object sender, FormClosingEventArgs e) {
    if (string.Equals((sender as Button).Name, @"CloseButton"))
        // Do something proper to CloseButton.
    else
        // Then assume that X has been clicked and act accordingly.
}

Otherwise, I have never ever needed to differentiate whether X or CloseButton was clicked, as I wanted to perform something specific on the FormClosing event, like closing all MdiChildren before closing the MDIContainerForm, or event checking for unsaved changes. Under these circumstances, we don't need, according to me, to differentiate from either buttons.

Closing by ALT+F4 will also trigger the FormClosing() event, as it sends a message to the Form that says to close. You may cancel the event by setting the

FormClosingEventArgs.Cancel = true. 

In our example, this would translate to be

e.Cancel = true.

Notice the difference between the FormClosing() and the FormClosed() events.

FormClosing occurs when the form received the message to be closed, and verify whether it has something to do before it is closed.

FormClosed occurs when the form is actually closed, so after it is closed.

Does this help?

In general, fixing corrupt objects can be pretty difficult. However, in this case, we're confident that the problem is an aborted transfer, meaning that the object is in a remote repository, so we should be able to safely remove our copy and let git get it from the remote, correctly this time.

The temporary object file, with zero size, can obviously just be removed. It's not going to do us any good. The corrupt object which refers to it, d4a0e75..., is our real problem. It can be found in .git/objects/d4/a0e75.... As I said above, it's going to be safe to remove, but just in case, back it up first.

At this point, a fresh git pull should succeed.

...assuming it was going to succeed in the first place. In this case, it appears that some local modifications prevented the attempted merge, so a stash, pull, stash pop was in order. This could happen with any merge, though, and didn't have anything to do with the corrupted object. (Unless there was some index cleanup necessary, and the stash did that in the process... but I don't believe so.)

The syntax has changed in that print is now a function. This means that the % formatting needs to be done inside the parenthesis:¹

print("%d. %s appears %d times." % (i, key, wordBank[key]))

However, since you are using Python 3.x., you should actually be using the newer str.format method:

print("{}. {} appears {} times.".format(i, key, wordBank[key]))

Though % formatting is not officially deprecated (yet), it is discouraged in favor of str.format and will most likely be removed from the language in a coming version (Python 4 maybe?).

_{¹Just a minor note: %d is the format specifier for integers, not %s.}

Try this:

/**
 * The template for displaying demo page
 *
 * template name: demo template
 *
 */

I came across this, tot it would be nice to share...

What do you guys think?

$(document).ready(function() {
  window.mousemove = function(e) {
    p = $(e).position();  //remember $(e) - could be any html tag also.. 
    left = e.left;        //retrieving the left position of the div... 
    top = e.top;          //get the top position of the div... 
  }
});

and boom, there we have it..

You're close.

The LIKE operator works with strings (CHAR, NVARCHAR, etc). so you need to concattenate the '%' symbol to the string...

MS SQL Server:

SELECT * FROM table1,table2 WHERE table1.x LIKE table2.y + '%'

Use of LIKE, however, is often slower than other operations. It's useful, powerful, flexible, but has performance considerations. I'll leave those for another topic though :)

EDIT:

I don't use MySQL, but this may work...

SELECT * FROM table1,table2 WHERE table1.x LIKE CONCAT(table2.y, '%')

If you are using a "Standard TCP/IP over SSH" type of connection, under "Preferences"->"Others" there is "SSH KeepAlive" field. It took me quite a while to find it :(

Some of the answers have already provided various approaches related to getting rid of the create extension and comment on extensions. For me, the following command line seemed to work and be the simplest approach to solve the problem:

cat /tmp/backup.sql.gz | gunzip - | \
  grep -v -E '(CREATE\ EXTENSION|COMMENT\ ON)' |  \
    psql --set ON_ERROR_STOP=on -U db_user -h localhost my_db

Some notes

• The first line is just uncompressing my backup and you may need to adjust accordingly.
• The second line is using grep to get rid of offending lines.
• the third line is my psql command; you may need to adjust as you normally would use psql for restore.

If you wish to ensure that the numbers being added are unique, you could use a Set object

if using 2.7 or greater, or import the sets module if not.

As others have mentioned, this means the numbers are not truly random.

One option is to use the delete method as follows:

StringBuffer sb = new StringBuffer();
for (int n = 0; n < 10; n++) {
   sb.append("a");

   // This will clear the buffer
   sb.delete(0, sb.length());
}

Another option (bit cleaner) uses setLength(int len):

sb.setLength(0);

See Javadoc for more info:

Just add a transition to the element you are messing with. Be aware that there could be some effects when the page loads. Like if you made a border radius change, you will see it when the dom loads.

.element {_x000D_
  width: 100px;_x000D_
  transition: all ease-in-out 0.5s;_x000D_
}_x000D_
 _x000D_
 .element:hover {_x000D_
  width: 200px;_x000D_
    transition: all ease-in-out 0.5s;_x000D_
}

I like simple javascript, and I usually have jQuery around. Here's what I came up with, based off mparkuk's:

function typeInTextarea(el, newText) {
  var start = el.prop("selectionStart")
  var end = el.prop("selectionEnd")
  var text = el.val()
  var before = text.substring(0, start)
  var after  = text.substring(end, text.length)
  el.val(before + newText + after)
  el[0].selectionStart = el[0].selectionEnd = start + newText.length
  el.focus()
}

$("button").on("click", function() {
  typeInTextarea($("textarea"), "some text")
  return false
})

Here's a demo: http://codepen.io/erikpukinskis/pen/EjaaMY?editors=101

You can do something like:

s = np.random.normal(2, 3, 1000)
import matplotlib.pyplot as plt
count, bins, ignored = plt.hist(s, 30, density=True)
plt.plot(bins, 1/(3 * np.sqrt(2 * np.pi)) * np.exp( - (bins - 2)**2 / (2 * 3**2) ), 
linewidth=2, color='r')
plt.show()

A thread is a set of (CPU)instructions which can be executed.

But in order to better understand the thread we have to have some knowledge about how the CPU and RAM works.

A computer follows instructions and manipulates data. RAM is the place where those instructions and data on which the CPU will operate on, are saved. Within the CPU some memory cells called registers exist. Those registers contain numbers on which the CPU performs simple mathematical operations. An example can be the following: “Add the number in register #3 to the number in register #1.”.

The collection of all operations a CPU can do is called instruction set. Each operation in the instruction set is assigned a number, so computer code is essentially a sequence of numbers representing CPU operations. These operations are stored as numbers in the RAM.

The CPU works in a never-ending loop, always fetching and executing an instruction from memory. At the core of this cycle is the PC register, or Program Counter. It's a special register that stores the memory address of the next instruction to be executed.

The CPU will:  

1. Fetch the instruction at the memory address given by the PC,
2. Increment the PC by 1,
3. Execute the instruction,
4. Go back to step 1.

The CPU can be instructed to write a new value to the PC, causing the execution to branch, or "jump" to somewhere else in the memory. And this branching can be conditional. For instance, a CPU instruction could say: "set PC to address #200 if register #1 equals zero". This allows computers to execute stuff like this:

if  x = 0
    compute_this()
else
    compute_that()

Resources taken from Computer Science Distilled were used.

I found it best to only update the calculation when a specific cell is changed. Here is an example VBA code to place in the "Worksheet" "Change" event:

Private Sub Worksheet_Change(ByVal Target As Range)
  If Not Intersect(Target, Range("F3")) Is Nothing Then
    Application.CalculateFull
  End If
End Sub

You can use __unused to tell the compiler that variable might not be used.

- (void)myMethod:(__unused NSObject *)theObject    
{
    // there will be no warning about `theObject`, because you wrote `__unused`

    __unused int theInt = 0;
    // there will be no warning, but you are still able to use `theInt` in the future
}

They are usually stored in the following folders:

/bin/
/usr/bin/
/sbin/
/usr/sbin/

If you're not sure, use the which command:

~$ which firefox
/usr/bin/firefox

This happened to me suddenly because my app's distribution profile had expired. Xcode began using the wildcard profile instead, which did not have the push notification entitlement enabled. I didn't receive any warning. The fix was easy; I just had to generate another distribution profile for my app in the Apple Developer Member Center, download it, and double-click to install in Xcode.

I would like to add that the height of the tree is the length of the longest path from the root to a leaf, and that the height of a node is the length of the longest path from that node to a leaf. The path means the number of nodes we encounter while traversing the tree between two nodes. In order to achieve O(log n) time complexity, the tree should be balanced, meaning that the difference of the height between the children of any node should be less than or equal to 1. Therefore, trees do not always guarantee a time complexity O(log n), unless they are balanced. Actually in some cases, the time complexity of searching in a tree can be O(n) in the worst case scenario.

You can take a look at the balance trees such as AVL tree. This one works on balancing the tree while inserting data in order to keep a time complexity of (log n) while searching in the tree.

It would be the former. Go by extensions as well instead of folder structure.

Update

I thought I'd provide an update from the comments below. Although not directly answering the OP's question, see the following for more examples of .gitignore syntax.

Community wiki (constantly being updated):

More examples with specific language use can be found here (thanks to Chris McKnight's comment):

Use git add -A, this will include the deleted files.

Note: use git rm for certain files.

1. Firstly, your have to confirm that you also access server api via your mac ip on mac browser. If not, make sure your server allow do that instead of just localhost (127.0.0.1) by runing your server on 0.0.0.0
2. Go to safari on iphone and make a get request by api your server serve: ex http://0.0.0.0/st. Safari auto redirect to server your mac runing (at your mac ip)
3. If you want to make request on your iphone app. It shoud be repalce requet 0.0.0.0 by [your mac/server ip]

I think this will do:

Dim filename As String
filename = Application.GetOpenFilename

At the beginning of your file you set raw_input to 0. Do not do this, at it modifies the built-in raw_input() function. Therefore, whenever you call raw_input(), it is essentially calling 0(), which raises the error. To remove the error, remove the first line of your code:
