I use python setup.py build_ext -R/usr/local/lib -I/usr/local/include/libcalg-1.0 and the compiled .so file is under the build folder. you can type python setup.py --help build_ext to see the explanations of -R and -I

Based on my personal experience with this knowledge base software, I would also like to join 'Julien H.' in suggesting PHPKB from http://www.knowledgebase-script.com

Personally I believe its one of the best. Many features, continously developed, excellent support & the GUI is just simple & great.

To do this without jQuery or any other library, you'll need to attach onMouseOver and onMouseOut events to each div and change the style in the event handlers.

For example:

var category = document.getElementById("catestory");
for (var child = category.firstChild; child != null; child = child.nextSibling) {
    if (child.nodeType == 1 && child.className == "content") {
        child.onmouseover = function() {
            this.style.backgroundColor = "#FF0000";
        }

        child.onmouseout = function() {
            // Set to transparent to let the original background show through.
            this.style.backgroundColor = "transparent"; 
        }
    }
}

If your h2 has not set its own background, the div background will show through and color it too.

You can create a new table using the following code.

SELECT IDENTITY (int, 1, 1) AS id, column1, column2
INTO dbo.NewTable
FROM dbo.OldTable

Then delete the old db, and rename the new db to the old db's name. Note: that column1 and column2 represent all the columns in your old table that you want to keep in your new table.

You can use global like so:

global._ = require('underscore')

ListViewItem item = new ListViewItem();
item.Text = "fdfdfd";
item.SubItems.Add ("melp");
listView.Items.Add(item);

The following code creates and prints an array of strings in shell:

#!/bin/bash
array=("A" "B" "ElementC" "ElementE")
for element in "${array[@]}"
do
    echo "$element"
done

echo
echo "Number of elements: ${#array[@]}"
echo
echo "${array[@]}"

Result:

A
B
ElementC
ElementE

Number of elements: 4

A B ElementC ElementE

In a past project that had to support IE8+ and I achieved this using a image encoded in data-url format.

The image was 2800x1px, half of the image white, and half transparent. Worked pretty well.

body {
    /* 50% right white */
    background: red url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAACvAAAAABAQAAAAAqT0YHAAAAAnRSTlMAAHaTzTgAAAAOSURBVHgBYxhi4P/QAgDwrK5SDPAOUwAAAABJRU5ErkJggg==) center top repeat-y;

   /* 50% left white */
   background: red url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAACvAAAAABAQAAAAAqT0YHAAAAAnRSTlMAAHaTzTgAAAAPSURBVHgBY/g/tADD0AIAIROuUgYu7kEAAAAASUVORK5CYII=) center top repeat-y;
}

You can see it working here JsFiddle. Hope it can help someone ;)

Typically, a thread is terminated when it's interrupted. So, why not use the native boolean? Try isInterrupted():

Thread t = new Thread(new Runnable(){
        @Override
        public void run() {
            while(!Thread.currentThread().isInterrupted()){
                // do stuff         
            }   
        }});
    t.start();

    // Sleep a second, and then interrupt
    try {
        Thread.sleep(1000);
    } catch (InterruptedException e) {}
    t.interrupt();

ref- How can I kill a thread? without using stop();

You might have output (maybe error/debug output) that precedes your call to

header("Content-type: text/xml");

Therefore, the content being delivered to the browser is not "xml"... that's what the error message is trying to tell you (at least that was the case for me and I had the same error message as you've described).

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

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

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

img = pygame.image.load(bytes_io)

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

I use frame and expand option. Very simple. I want some buttons in the middle of screen. Resize window and button stay in the middle. This is my solution.

frame = Frame(parent_window)
Button(frame, text='button1', command=command_1).pack(fill=X)
Button(frame, text='button2', command=command_2).pack(fill=X)
Button(frame, text='button3', command=command_3).pack(fill=X)
frame.pack(anchor=CENTER, expand=1)

mkdirs() also creates parent directories in the path this File represents.

javadocs for mkdirs():

Creates the directory named by this abstract pathname, including any necessary but nonexistent parent directories. Note that if this operation fails it may have succeeded in creating some of the necessary parent directories.

javadocs for mkdir():

Creates the directory named by this abstract pathname.

Example:

File  f = new File("non_existing_dir/someDir");
System.out.println(f.mkdir());
System.out.println(f.mkdirs());

will yield false for the first [and no dir will be created], and true for the second, and you will have created non_existing_dir/someDir

I also faced the similar issues, changing the version from 2.0.0.RELEASE to 1.5.10.RELEASE worked for me, please try it before downgrading the maven version

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.10.RELEASE</version>
</parent>
<dependencies>
 <dependency>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-starter-web</artifactId>
 </dependency>  
</dependencies>

this worked for me:-

<?php echo '<pre>' . print_r($_SESSION, TRUE) . '</pre>'; ?>

thanks for sharing code...

The 'u' in front of the string values means the string is a Unicode string. Unicode is a way to represent more characters than normal ASCII can manage. The fact that you're seeing the u means you're on Python 2 - strings are Unicode by default on Python 3, but on Python 2, the u in front distinguishes Unicode strings. The rest of this answer will focus on Python 2.

You can create a Unicode string multiple ways:

>>> u'foo'
u'foo'
>>> unicode('foo') # Python 2 only
u'foo'

But the real reason is to represent something like this (translation here):

>>> val = u'???????????? ? ?????????????'
>>> val
u'\u041e\u0437\u043d\u0430\u043a\u043e\u043c\u044c\u0442\u0435\u0441\u044c \u0441 \u0434\u043e\u043a\u0443\u043c\u0435\u043d\u0442\u0430\u0446\u0438\u0435\u0439'
>>> print val
???????????? ? ?????????????

For the most part, Unicode and non-Unicode strings are interoperable on Python 2.

There are other symbols you will see, such as the "raw" symbol r for telling a string not to interpret backslashes. This is extremely useful for writing regular expressions.

>>> 'foo\"'
'foo"'
>>> r'foo\"'
'foo\\"'

Unicode and non-Unicode strings can be equal on Python 2:

>>> bird1 = unicode('unladen swallow')
>>> bird2 = 'unladen swallow'
>>> bird1 == bird2
True

but not on Python 3:

>>> x = u'asdf' # Python 3
>>> y = b'asdf' # b indicates bytestring
>>> x == y
False

I prefer to use a looping variable, as it tends to read a bit nicer than just "while 1:", and no ugly-looking break statement:

finished = False
while not finished:
    ... do something...
    finished = evaluate_end_condition()

I believe the simplest method would be to use Python:

python -m webbrowser "http://www.example.com/"

If you run in linux, open file netbeans.conf using nano or anything else.

nano netbeans-8.2/etc/netbeans.conf

and edit jdkhome or directory for jdk

netbeans_jdkhome="/usr/lib/jvm/java-1.8.0-openjdk-amd64"

you can check your jdk version with

java -version

or

ls /usr/lib/jvm

Just use ng-repeat="(sectionIndex, section) in sections"

and that will be useable on the next level ng-repeat down.

<ul ng-repeat="(sectionIndex, section) in sections">
    <li  class="section_title {{section.active}}" >
        {{section.name}}
    </li>
    <ul>
        <li ng-repeat="tutorial in section.tutorials">
            {{tutorial.name}}, Your section index is {{sectionIndex}}
        </li>
    </ul>
</ul>

You can also count on multiple groups and their intersection:

self.session.query(func.count(Table.column1),Table.column1, Table.column2).group_by(Table.column1, Table.column2).all()

The query above will return counts for all possible combinations of values from both columns.

Look at real_ates ES2016 way, it's more correct.

import crypto from 'crypto';

function spawnTokenBuf() {
    return function(callback) {
        crypto.randomBytes(48, callback);
    };
}

async function() {
    console.log((await spawnTokenBuf()).toString('base64'));
};

Generator/Yield Way

var crypto = require('crypto');
var co = require('co');

function spawnTokenBuf() {
    return function(callback) {
        crypto.randomBytes(48, callback);
    };
}

co(function* () {
    console.log((yield spawnTokenBuf()).toString('base64'));
});

This script detects all versions of Firefox, for Desktop, from version 1 to 46.

It's the third time I've tried to answer this question on StackOverflow because I kept finding new ways to break my script. However, I think it's working now. It's a great exercise to learn about Firefox features and interesting to see how things have evolved. The script can be rewritten with different features, I chose ones I thought would be most useful, I would love for someone else to rewrite with other more useful features and post here, and compare results.

I placed the script in a try statement in case the user has any disabled settings in about.config. Otherwise I tested on every version of Firefox and it detects each one. I gave a brief description of what each feature is used for in the comments. I would like to do this for Webkit too but find the documentation not as good. Mozilla has easy to download previous versions and detailed releases.

IMHO I think that all the models have a great place but the problem I have with the model first approach is in many large businesses with DBA's controlling the databases you do not get the flexibility of building applications without using database first approaches. I have worked on many projects and when it came to deployment they wanted full control.

So as much as I agree with all the possible variations Code First, Model First, Database first, you must consider the actual production environment. So if your system is going to be a large user base application with many users and DBA's running the show then you might consider the Database first option just my opinion.

import java.util.Scanner;
public class Solution {

    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        double d = scan.nextDouble();
        String s="";
        while(scan.hasNext())
        {
            s=scan.nextLine();
        }

        System.out.println("String: " +s);
        System.out.println("Double: " + d);
        System.out.println("Int: " + i);
    }
}

Q. List the name of each show, and the number of different times it has been held. List the show which has been held most often first.

event_id show_id event_name judge_id
0101    01  Dressage        01
0102    01  Jumping         02
0103    01  Led in          01
0201    02  Led in          02
0301    03  Led in          01
0401    04  Dressage        04
0501    05  Dressage        01
0502    05  Flag and Pole   02

Ans:

select event_name, count(show_id) as held_times from event 
group by event_name 
order by count(show_id) desc

If you are stuck on django 1.2 like I am and RedirectView doesn't exist, another route-centric way to add the redirect mapping is using:

(r'^match_rules/$', 'django.views.generic.simple.redirect_to', {'url': '/new_url'}),  

You can also re-route everything on a match. This is useful when changing the folder of an app but wanting to preserve bookmarks:

(r'^match_folder/(?P<path>.*)', 'django.views.generic.simple.redirect_to', {'url': '/new_folder/%(path)s'}),  

This is preferable to django.shortcuts.redirect if you are only trying to modify your url routing and do not have access to .htaccess, etc (I'm on Appengine and app.yaml doesn't allow url redirection at that level like an .htaccess).

For Print Result to text file

we can follow

echo "test data" > test.txt

This will create test.txt file and written "test data"

If you want to append then

echo "test data" >> test.txt

Following these steps allows you to install tensorflow and keras:

1. Download Anaconda3-5.2.0 which comes with python 3.6 from https://repo.anaconda.com/archive/

2. Install Anaconda and open Anaconda Prompt and execute below commands

   conda install jupyter 
   conda install scipy
   pip install sklearn
   pip install msgpack
   pip install pandas
   pip install pandas-datareader
   pip install matplotlib 
   pip install pillow
   pip install requests
   pip install h5py
   pip install tensorflow
   pip install keras
   

You can use twitter search page to bypass 3,200 limit. However you have to scroll down many times in the search results page. For example, I searched tweets from @beyinsiz_adam. This is the link of search results: https://twitter.com/search?q=from%3Abeyinsiz_adam&src=typd&f=realtime

Now in order to scroll down many times, you can use the following javascript code.

    var myVar=setInterval(function(){myTimer()},1000);
    function myTimer() {
        window.scrollTo(0,document.body.scrollHeight);
    }

Just run it in the FireBug console. And wait some time to load all tweets.

Another java 8 lambda option :

String[] array2 = Arrays.stream(array).map(String::trim).toArray(String[]::new);

And the ugly but optimized version without new array creation

Arrays.stream(array).map(String::trim).toArray(unused -> array);

Original "array" is modified.

if we make the particular activity as

android:exported="true"

it will be the launching activity. Click on the module name just to the left of the run button and click on "Edit configurations..." Now make sure "Launch default Activity" is selected.

You are most likely not using the correct credentials for the MySQL server. You also need to ensure the user you are connecting as has the correct privileges to view databases/tables, and that you can connect from your current location in network topographic terms (localhost).

When you want monitor specified process, usually it is done by scripting. Here is perl example. This put percents as the same way as top, scalling it to one CPU. Then when some process is active working with 2 threads, cpu usage can be more than 100%. Specially look how cpu cores are counted :D then let me show my example:

#!/usr/bin/perl

my $pid=1234; #insert here monitored process PID

#returns current process time counters or single undef if unavailable
#returns:  1. process counter  , 2. system counter , 3. total system cpu cores
sub GetCurrentLoads {
    my $pid=shift;
    my $fh;
    my $line;
    open $fh,'<',"/proc/$pid/stat" or return undef;
    $line=<$fh>;
    close $fh;
    return undef unless $line=~/^\d+ \([^)]+\) \S \d+ \d+ \d+ \d+ -?\d+ \d+ \d+ \d+ \d+ \d+ (\d+) (\d+)/;
    my $TimeApp=$1+$2;
    my $TimeSystem=0;
    my $CpuCount=0;
    open $fh,'<',"/proc/stat" or return undef;
    while (defined($line=<$fh>)) {
        if ($line=~/^cpu\s/) {
            foreach my $nr ($line=~/\d+/g) { $TimeSystem+=$nr; };
            next;
        };
        $CpuCount++ if $line=~/^cpu\d/;
    }
    close $fh;
    return undef if $TimeSystem==0;
    return $TimeApp,$TimeSystem,$CpuCount;
}

my ($currApp,$currSys,$lastApp,$lastSys,$cores);
while () {
    ($currApp,$currSys,$cores)=GetCurrentLoads($pid);
    printf "Load is: %5.1f\%\n",($currApp-$lastApp)/($currSys-$lastSys)*$cores*100 if defined $currApp and defined $lastApp and defined $currSys and defined $lastSys;
    ($lastApp,$lastSys)=($currApp,$currSys);
    sleep 1;
}

I hope it will help you in any monitoring. Of course you should use scanf or other C functions for converting any perl regexpes I've used to C source. Of course 1 second for sleeping is not mandatory. you can use any time. effect is, you will get averrage load on specfied time period. When you will use it for monitoring, of course last values you should put outside. It is needed, because monitoring usually calls scripts periodically, and script should finish his work asap.

Try this:

select sum(num_tax_amount+num_total_amount) from table_name;

// Get the focused element:
var $focused = $(':focus');

// No jQuery:
var focused = document.activeElement;

// Does the element have focus:
var hasFocus = $('foo').is(':focus');

// No jQuery:
elem === elem.ownerDocument.activeElement;

Which one should you use? quoting the jQuery docs:

As with other pseudo-class selectors (those that begin with a ":"), it is recommended to precede :focus with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare $(':focus') is equivalent to $('*:focus'). If you are looking for the currently focused element, $( document.activeElement ) will retrieve it without having to search the whole DOM tree.

The answer is:

document.activeElement

And if you want a jQuery object wrapping the element:

$(document.activeElement)

No, sadly:

The Excel 2010 client application does not support co-authoring workbooks in SharePoint Server 2010. However, the Excel client application does support non-real-time co-authoring workbooks stored locally or on network (UNC) paths by using the Shared Workbook feature. Co-authoring workbooks in SharePoint is supported by using the Microsoft Excel Web App, included with Office Web Apps

From Co-authoring overview (SharePoint Server 2010)

...and not for SharePoint 2013 either. Though it works for pretty much all other Office documents. Go figure.

Your null pointer exception seems to be on this line:

String url = intent.getExtras().getString("userurl");

because intent.getExtras() returns null when the intent doesn't have any extras.

You have to realize that this piece of code:

Intent Main = new Intent(this, ToClass.class);
Main.putExtra("userurl", url);
startActivity(Main);

doesn't start the activity you wrote in Main.java, it will attempt to start an activity called ToClass and if that doesn't exist, your app crashes.

Also, there is no such thing as "android.intent.action.start" so the manifest should look more like:

<activity android:name=".start" android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
<activity android:name= ".Main">
</activity>

I hope this fixes some of the issues you are encountering but I strongly suggest you check out some "getting started" tutorials for android development and build up from there.

I fix the problem with under statement ; send data with url same GET methode

$.ajax({
    url: 'includes/get_ajax_function.php?value=jack&id='+id,
    type: 'post',
    data: $('#b-info1').serializeArray(),

and get value with $_REQUEST['value'] OR $_GET['id']

Something that just happened to me and caused me some headaches:

I have set up a new Linux RabbitMQ server and used a shell script to set up my own custom users (not guest!).

The script had several of those "code" blocks:

rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

Very similar to the one in Gabriele's answer, so I take his code and don't need to redact passwords.

Still I was not able to log in in the management console. Then I noticed that I had created the setup script in Windows (CR+LF line ending) and converted the file to Linux (LF only), then reran the setup script on my Linux server.

... and was still not able to log in, because it took another 15 minutes until I realized that calling add_user over and over again would not fix the broken passwords (which probably ended with a CR character). I had to call change_password for every user to fix my earlier mistake:

rabbitmqctl change_password test test

(Another solution would have been to delete all users and then call the script again)

this can be resolved by copying the below code in application.properties

spring.thymeleaf.enabled=false

You have a JSON object that contains an Array. You need to access the array results. Change your code to:

this.data = res.json().results

Place the following in your jQuery mouseover event handler:

$(this).css('color', 'red');

To set both color and size at the same time:

$(this).css({ 'color': 'red', 'font-size': '150%' });

You can set any CSS attribute using the .css() jQuery function.

Just as an addendum to OP accepted answer:

If you having issues with

fatal: bad object xxxxx

that's because you don't have access to that commit. Which means you don't have that repo stored locally. Then:

git remote add LABEL_FOR_THE_REPO REPO_YOU_WANT_THE_COMMIT_FROM
git fetch LABEL_FOR_THE_REPO
git cherry-pick xxxxxxx

Where xxxxxxx is the commit hash you want.

You need to define the output parameter as an output parameter in the code with the ParameterDirection.Output enumeration. There are numerous examples of this out there, but here's one on MSDN.

You can't alloc UIImage, this is impossible. Proper code with UIImageView allocate:

UIImageView *_image = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"something.png"]] ;

CGContextDrawImage(context, rect, _image.image.CGImage);

You can utilize the dependency management mechanism.

If you create entries in the <dependencyManagement> section of your pom for spring-security-web and spring-web with the desired 3.1.0 version set the managed version of the artifact will override those specified in the transitive dependency tree.

I'm not sure if that really saves you any code, but it is a cleaner solution IMO.

If you prefer immutable data objects, or if you just dont want to be destructive to the input list, you can use Guava's predicates.

ImmutableList.copyOf(Iterables.filter(tourists, Predicates.notNull()))

I understand that this question is a bit old but I'm going to introduce another solution using redux-observable aka. Epic.

Quoting the official documentation:

What is redux-observable?

RxJS 5-based middleware for Redux. Compose and cancel async actions to create side effects and more.

An Epic is the core primitive of redux-observable.

It is a function which takes a stream of actions and returns a stream of actions. Actions in, actions out.

In more or less words, you can create a function that receives actions through a Stream and then return a new stream of actions (using common side effects such as timeouts, delays, intervals, and requests).

Let me post the code and then explain a bit more about it

store.js

import {createStore, applyMiddleware} from 'redux'
import {createEpicMiddleware} from 'redux-observable'
import {Observable} from 'rxjs'
const NEW_NOTIFICATION = 'NEW_NOTIFICATION'
const QUIT_NOTIFICATION = 'QUIT_NOTIFICATION'
const NOTIFICATION_TIMEOUT = 2000

const initialState = ''
const rootReducer = (state = initialState, action) => {
  const {type, message} = action
  console.log(type)
  switch(type) {
    case NEW_NOTIFICATION:
      return message
    break
    case QUIT_NOTIFICATION:
      return initialState
    break
  }

  return state
}

const rootEpic = (action$) => {
  const incoming = action$.ofType(NEW_NOTIFICATION)
  const outgoing = incoming.switchMap((action) => {
    return Observable.of(quitNotification())
      .delay(NOTIFICATION_TIMEOUT)
      //.takeUntil(action$.ofType(NEW_NOTIFICATION))
  });

  return outgoing;
}

export function newNotification(message) {
  return ({type: NEW_NOTIFICATION, message})
}
export function quitNotification(message) {
  return ({type: QUIT_NOTIFICATION, message});
}

export const configureStore = () => createStore(
  rootReducer,
  applyMiddleware(createEpicMiddleware(rootEpic))
)

index.js

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import {configureStore} from './store.js'
import {Provider} from 'react-redux'

const store = configureStore()

ReactDOM.render(
  <Provider store={store}>
    <App />
  </Provider>,
  document.getElementById('root')
);

App.js

import React, { Component } from 'react';
import {connect} from 'react-redux'
import {newNotification} from './store.js'

class App extends Component {

  render() {
    return (
      <div className="App">
        {this.props.notificationExistance ? (<p>{this.props.notificationMessage}</p>) : ''}
        <button onClick={this.props.onNotificationRequest}>Click!</button>
      </div>
    );
  }
}

const mapStateToProps = (state) => {
  return {
    notificationExistance : state.length > 0,
    notificationMessage : state
  }
}

const mapDispatchToProps = (dispatch) => {
  return {
    onNotificationRequest: () => dispatch(newNotification(new Date().toDateString()))
  }
}

export default connect(mapStateToProps, mapDispatchToProps)(App)

The key code to solve this problem is as easy as pie as you can see, the only thing that appears different from the other answers is the function rootEpic.

Point 1. As with sagas, you have to combine the epics in order to get a top level function that receives a stream of actions and returns a stream of actions, so you can use it with the middleware factory createEpicMiddleware. In our case we only need one so we only have our rootEpic so we don't have to combine anything but it's a good to know fact.

Point 2. Our rootEpic which takes care about the side effects logic only takes about 5 lines of code which is awesome! Including the fact that is pretty much declarative!

Point 3. Line by line rootEpic explanation (in comments)

const rootEpic = (action$) => {
  // sets the incoming constant as a stream 
  // of actions with  type NEW_NOTIFICATION
  const incoming = action$.ofType(NEW_NOTIFICATION)
  // Merges the "incoming" stream with the stream resulting for each call
  // This functionality is similar to flatMap (or Promise.all in some way)
  // It creates a new stream with the values of incoming and 
  // the resulting values of the stream generated by the function passed
  // but it stops the merge when incoming gets a new value SO!,
  // in result: no quitNotification action is set in the resulting stream
  // in case there is a new alert
  const outgoing = incoming.switchMap((action) => {
    // creates of observable with the value passed 
    // (a stream with only one node)
    return Observable.of(quitNotification())
      // it waits before sending the nodes 
      // from the Observable.of(...) statement
      .delay(NOTIFICATION_TIMEOUT)
  });
  // we return the resulting stream
  return outgoing;
}

I hope it helps!

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

Check if you have Chrome App Launcher. You can usually see it in your toolbar. It runs as a second instance of chrome, but unlike the browser, it auto-runs so is going to be running whenever you start your PC. Even though it isn't a browser view, it is a chrome instance which is enough to prevent your arguments from taking effect. Go to your task manager and you will probably have to kill 2 chrome processes.

A modification of the code by @CarloCannas:

public static void sudo(String...strings) {
    try{
        Process su = Runtime.getRuntime().exec("su");
        DataOutputStream outputStream = new DataOutputStream(su.getOutputStream());

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        outputStream.close();
    }catch(IOException e){
        e.printStackTrace();
    }
}

(You are welcome to find a better place for outputStream.close())

Usage example:

private static void suMkdirs(String path) {
    if (!new File(path).isDirectory()) {
        sudo("mkdir -p "+path);
    }
}

Update: To get the result (the output to stdout), use:

public static String sudoForResult(String...strings) {
    String res = "";
    DataOutputStream outputStream = null;
    InputStream response = null;
    try{
        Process su = Runtime.getRuntime().exec("su");
        outputStream = new DataOutputStream(su.getOutputStream());
        response = su.getInputStream();

        for (String s : strings) {
            outputStream.writeBytes(s+"\n");
            outputStream.flush();
        }

        outputStream.writeBytes("exit\n");
        outputStream.flush();
        try {
            su.waitFor();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        res = readFully(response);
    } catch (IOException e){
        e.printStackTrace();
    } finally {
        Closer.closeSilently(outputStream, response);
    }
    return res;
}
public static String readFully(InputStream is) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int length = 0;
    while ((length = is.read(buffer)) != -1) {
        baos.write(buffer, 0, length);
    }
    return baos.toString("UTF-8");
}

The utility to silently close a number of Closeables (So?ket may be no Closeable) is:

public class Closer {
// closeAll()
public static void closeSilently(Object... xs) {
    // Note: on Android API levels prior to 19 Socket does not implement Closeable
    for (Object x : xs) {
        if (x != null) {
            try {
                Log.d("closing: "+x);
                if (x instanceof Closeable) {
                    ((Closeable)x).close();
                } else if (x instanceof Socket) {
                    ((Socket)x).close();
                } else if (x instanceof DatagramSocket) {
                    ((DatagramSocket)x).close();
                } else {
                    Log.d("cannot close: "+x);
                    throw new RuntimeException("cannot close "+x);
                }
            } catch (Throwable e) {
                Log.x(e);
            }
        }
    }
}
}

Encountered the same issue with a ASP.Net Web App and two library class projects which needed to be referenced within the Web App. I had no information provided on why the build failed and the references were invalid.

Solution was to ensure all projects had the same Target Framework:

In Visual Studio 2015- Right Click project > Properties > Application > Target Framework

Save, Clean and Rebuild solution. The project references should no longer appear as yellow warnings and the solution will compile.

My Web App was targeting .Net 4.5 whereas the other two dependent library class projects targeted .Net v4.5.2

End Sub

but I don't understand, why xmldoc4 should be loaded each time.

A naive approach could look like this:

#include <map>
#include <sstream>
#include <stdexcept>
#include <string>

std::map<std::string, std::string> options; // global?

void parse(std::istream & cfgfile)
{
    for (std::string line; std::getline(cfgfile, line); )
    {
        std::istringstream iss(line);
        std::string id, eq, val;

        bool error = false;

        if (!(iss >> id))
        {
            error = true;
        }
        else if (id[0] == '#')
        {
            continue;
        }
        else if (!(iss >> eq >> val >> std::ws) || eq != "=" || iss.get() != EOF)
        {
            error = true;
        }

        if (error)
        {
            // do something appropriate: throw, skip, warn, etc.
        }
        else
        {
            options[id] = val;
        }
    }
}

Now you can access each option value from the global options map anywhere in your program. If you want castability, you could make the mapped type a boost::variant.

I come to Pandas from an R background, and I see that Pandas is more complicated when it comes to selecting rows or columns.

I had to wrestle with it for a while, and then I found some ways to deal with:

Getting the number of columns:

len(df.columns)
## Here:
# df is your data.frame
# df.columns returns a string. It contains column's titles of the df.
# Then, "len()" gets the length of it.

Getting the number of rows:

len(df.index) # It's similar.

with latest Glide library

use Gradle:

repositories {
  mavenCentral()
  google()
}

dependencies {
  implementation 'com.github.bumptech.glide:glide:4.8.0'
  annotationProcessor 'com.github.bumptech.glide:compiler:4.8.0'
}

in activity or fragment:

ImageView imageView = findViewById(R.id.imageView);

/* from internet*/
Glide.with(this)
        .load("https://media.giphy.com/media/98uBZTzlXMhkk/giphy.gif")
        .into(imageView);

/*from raw folder*/
Glide.with(this)
        .load(R.raw.giphy)
        .into(imageView);

In case your goal is to have a rotated image in an imageView or file you can use Exif to achieve that. The support library now offers that: https://android-developers.googleblog.com/2016/12/introducing-the-exifinterface-support-library.html

Below is its usage but to achieve your goal you have to check the library api documentation for that. I just wanted to give a hint that rotating the bitmap isn't always the best way.

Uri uri; // the URI you've received from the other app
InputStream in;
try {
  in = getContentResolver().openInputStream(uri);
  ExifInterface exifInterface = new ExifInterface(in);
  // Now you can extract any Exif tag you want
  // Assuming the image is a JPEG or supported raw format
} catch (IOException e) {
  // Handle any errors
} finally {
  if (in != null) {
    try {
      in.close();
    } catch (IOException ignored) {}
  }
}

int rotation = 0;
int orientation = exifInterface.getAttributeInt(
    ExifInterface.TAG_ORIENTATION,
    ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
  case ExifInterface.ORIENTATION_ROTATE_90:
    rotation = 90;
    break;
  case ExifInterface.ORIENTATION_ROTATE_180:
    rotation = 180;
    break;
  case ExifInterface.ORIENTATION_ROTATE_270:
    rotation = 270;
    break;
}

dependency

compile "com.android.support:exifinterface:25.1.0"

Try using absolute positioning, rather than relative positioning

this should get you close - you can adjust by tweaking margins or top/left positions

#play_button {
    position:absolute;
    transition: .5s ease;
    top: 50%;
    left: 50%;
}

Laravel's Autoload is a bit different:

1) It will in fact use Composer for some stuff

2) It will call Composer with the optimize flag

3) It will 'recompile' loads of files creating the huge bootstrap/compiled.php

4) And also will find all of your Workbench packages and composer dump-autoload them, one by one.

np_clip = numpy.clip
mm_clip = lambda x, l, u: max(l, min(u, x))
s_clip = lambda x, l, u: sorted((x, l, u))[1]

paxdiablo has it!, use plain ol' python. The numpy version is, perhaps not surprisingly, the slowest of the lot. Probably because it's looking for arrays, where the other versions just order their arguments.

To anyone else who ended up here while searching for info on how to decode a string encoded with Base64.encodeBytes(), here was my solution:

// encode
String ps = "techPass";
String tmp = Base64.encodeBytes(ps.getBytes());

// decode
String ps2 = "dGVjaFBhC3M=";
byte[] tmp2 = Base64.decode(ps2); 
String val2 = new String(tmp2, "UTF-8"); 

Also, I'm supporting older versions of Android so I'm using Robert Harder's Base64 library from http://iharder.net/base64

Why not just do

if(BuildConfig.DEBUG)
  Log.d("tag","msg");

? No additional libraries needed, no proguard rules which tend to screw up the project and java compiler will just leave out bytecode for for this call when you make release build.

dict = {}
for i in set(str):
    b = str.count(i, 0, len(str))
    dict[i] = b
print dict

If my string is:

str = "this is string!"

Above code will print:

{'!': 1, ' ': 2, 'g': 1, 'i': 3, 'h': 1, 'n': 1, 's': 3, 'r': 1, 't': 2}

In .NET 4 you don't need the ToArray() call - string.Join is overloaded to accept IEnumerable<T> or just IEnumerable<string>.

There are potentially more efficient ways of doing it before .NET 4, but do you really need them? Is this actually a bottleneck in your code?

You could iterate over the list, work out the final size, allocate a StringBuilder of exactly the right size, then do the join yourself. That would avoid the extra array being built for little reason - but it wouldn't save much time and it would be a lot more code.

The primary goal of a hashmap is to store a data set and provide near constant time lookups on it using a unique key. There are two common styles of hashmap implementation:

• Separate chaining: one with an array of buckets (linked lists)
• Open addressing: a single array allocated with extra space so index collisions may be resolved by placing the entry in an adjacent slot.

Separate chaining is preferable if the hashmap may have a poor hash function, it is not desirable to pre-allocate storage for potentially unused slots, or entries may have variable size. This type of hashmap may continue to function relatively efficiently even when the load factor exceeds 1.0. Obviously, there is extra memory required in each entry to store linked list pointers.

Hashmaps using open addressing have potential performance advantages when the load factor is kept below a certain threshold (generally about 0.7) and a reasonably good hash function is used. This is because they avoid potential cache misses and many small memory allocations associated with a linked list, and perform all operations in a contiguous, pre-allocated array. Iteration through all elements is also cheaper. The catch is hashmaps using open addressing must be reallocated to a larger size and rehashed to maintain an ideal load factor, or they face a significant performance penalty. It is impossible for their load factor to exceed 1.0.

Some key performance metrics to evaluate when creating a hashmap would include:

• Maximum load factor
• Average collision count on insertion
• Distribution of collisions: uneven distribution (clustering) could indicate a poor hash function.
• Relative time for various operations: put, get, remove of existing and non-existing entries.

Here is a flexible hashmap implementation I made. I used open addressing and linear probing for collision resolution.

Use summary and munge the output into something useful!

library(tidyr)
library(dplyr)

df %>% 
  summary %>% 
  data.frame %>%
  select(-Var1) %>%
  separate(data=.,col=Freq,into = c('metric','value'),sep = ':') %>%
  rename(column_name=Var2) %>%
  mutate(value=as.numeric(value),
         metric = trimws(metric,'both') 
  ) %>%  
  filter(!is.na(value)) -> metrics

It's not pretty and it is certainly not fast but it gets the job done!

Using pipeline:

echo your_pswd | sudo -S your_cmd

Using here-document:

sudo -S cmd <<eof
pwd
eof
#remember to put the above two lines without "any" indentations.

Open a terminal to ask password (whichever works):

gnome-terminal -e "sudo cmd"

xterm -e "sudo cmd"

To find the Flutter SDK path [ used Windows10 ]

1. In your Android Studio home page on the bottom right click on Configure
2. Then Click on SDK Manager
3. Then on System Settings
4. Then on AndroidSDK

You will see the path at the top

In JQuery you can call

$("form:first").trigger("submit")

Don't know if that is much better. I think form.submit(); is pretty universal.

Solution for loading an external website into an iFrame even tough the x-frame option is set to deny on the external website.

If you want to load a other website into an iFrame and you get the Display forbidden by X-Frame-Options” error then you can actually overcome this by creating a server side proxy script.

The src attribute of the iFrame could have an url looking like this: /proxy.php?url=https://www.example.com/page&key=somekey

Then proxy.php would look something like:

if (isValidRequest()) {
   echo file_get_contents($_GET['url']);
}

function isValidRequest() {
    return $_SERVER['REQUEST_METHOD'] === 'GET' && isset($_GET['key']) && 
    $_GET['key'] === 'somekey';
}

This by passes the block, because it is just a GET request that might as wel have been a ordinary browser page visit.

Be aware: You might want to improve the security in this script. Because hackers could start loading in webpages via your proxy script.

This problem arises due to incompatible JDK version. Download and install latest JDK(currently its 8) from java official site in case you are using previous versions. Then in Android Studio go to File->Project Structure->SDK location -> JDK location and set it to 'C:\Program Files\Java\jdk1.8.0_121' (Default location of JDK). Gradle sync your project and you are all set...

If you are using iframe for vimeo, change the url from:

https://vimeo.com/63534746

to:

http://player.vimeo.com/video/63534746

It works for me.

My guess is Nuget Package Manager is messing up with VSO. I create a new project, add packages to it just fine, check in TFS. Then I go home, "Get Latest Version", and Run, and fail because Nuget Package Manager doesn't restore my packages. Solution: on my home machine

1. open Nuget Package Manger, uninstall every packaged that have installed
2. Open References folder, right click > Delete for all the packages you've installed
3. Re-install them via Nuget Package Manager
4. Check in

You can also "fix" this by replacing the image with its inline Base64 representation:

img.src= "data:image/gif;base64,R0lGODlhCwALAIAAAAAA3pn/ZiH5BAEAAAEALAAAAAALAAsAAAIUhA+hkcuO4lmNVindo7qyrIXiGBYAOw==";

if you user $criteria, I recommend blow usage:

$criteria = new CDbCriteria();
$criteria->compare('email_id', 101);
$comments = EmailArchive::model()->findAll($criteria);

Might found a solution very easy which you only need to create different type of
. Seem to have worked for me.

example : (html code)

<br/ class="150%space">

(css code)

br[class='150%space']
{
   line-height: 150%;
}

For those who are looking for a tiny and smart solution:

String.prototype.toDate = function(format)
{
  var normalized      = this.replace(/[^a-zA-Z0-9]/g, '-');
  var normalizedFormat= format.toLowerCase().replace(/[^a-zA-Z0-9]/g, '-');
  var formatItems     = normalizedFormat.split('-');
  var dateItems       = normalized.split('-');

  var monthIndex  = formatItems.indexOf("mm");
  var dayIndex    = formatItems.indexOf("dd");
  var yearIndex   = formatItems.indexOf("yyyy");
  var hourIndex     = formatItems.indexOf("hh");
  var minutesIndex  = formatItems.indexOf("ii");
  var secondsIndex  = formatItems.indexOf("ss");

  var today = new Date();

  var year  = yearIndex>-1  ? dateItems[yearIndex]    : today.getFullYear();
  var month = monthIndex>-1 ? dateItems[monthIndex]-1 : today.getMonth()-1;
  var day   = dayIndex>-1   ? dateItems[dayIndex]     : today.getDate();

  var hour    = hourIndex>-1      ? dateItems[hourIndex]    : today.getHours();
  var minute  = minutesIndex>-1   ? dateItems[minutesIndex] : today.getMinutes();
  var second  = secondsIndex>-1   ? dateItems[secondsIndex] : today.getSeconds();

  return new Date(year,month,day,hour,minute,second);
};

Example:

"22/03/2016 14:03:01".toDate("dd/mm/yyyy hh:ii:ss");
"2016-03-29 18:30:00".toDate("yyyy-mm-dd hh:ii:ss");

new String(byteArray, Charset.defaultCharset())

This will convert a byte array to the default charset in java. It may throw exceptions depending on what you supply with the byteArray.

To use center alignment in ionic app code itself, you can use the following code:

<ion-row center>  
 <ion-col text-center>   
  <button ion-button>Search</button>  
 </ion-col> 
</ion-row>

To use right alignment in ionic app code itself, you can use the following code:

<ion-row right>  
 <ion-col text-right>   
  <button ion-button>Search</button>  
 </ion-col> 
</ion-row>

Object Model is concerned with the following three concepts Data Abstraction Encapsulation Inheritance The relational model used the basic concept of a relation or table. Object-relational mapping (OR mapping) products integrate object programming language capabilities with relational databases.

The proper answer to your question is to use statistics.mean. But for fun, here is a version of mean that does not use the len() function, so it (like statistics.mean) can be used on generators, which do not support len():

from functools import reduce
from operator import truediv
def ave(seq):
    return truediv(*reduce(lambda a, b: (a[0] + b[1], b[0]), 
                           enumerate(seq, start=1), 
                           (0, 0)))

Use the jQuery ajaxSetup function, that can set up default values for all ajax requests.

$.ajaxSetup({
  headers: {
    'Authorization': "Basic XXXXX"
  }
});

yourTextField.tintColor = [UIColor whiteColor];

It works if you set it in code, 'cos somehow color trigger doesn't do it in the Interface Builder (Xcode 6.1.1). It suited well without a need to change any appearance proxy.

The selector returns an array of jQuery objects. If no matching elements are found, it returns an empty array. You can check the .length of the collection returned by the selector or check whether the first array element is 'undefined'.

You can use any the following examples inside an IF statement and they all produce the same result. True, if the selector found a matching element, false otherwise.

$('#notAnElement').length > 0
$('#notAnElement').get(0) !== undefined
$('#notAnElement')[0] !== undefined

import itertools
ab = itertools.chain(['it'], ['was'], ['annoying'])

Just another method....

SELECT word, COUNT(*) FROM words GROUP by word HAVING COUNT(*) > 1

How do they achieve internally that you are able to pass something like x > 5 into a method?

The short answer is that they don't.

Any sort of logical operation on a numpy array returns a boolean array. (i.e. __gt__, __lt__, etc all return boolean arrays where the given condition is true).

E.g.

x = np.arange(9).reshape(3,3)
print x > 5

yields:

array([[False, False, False],
       [False, False, False],
       [ True,  True,  True]], dtype=bool)

This is the same reason why something like if x > 5: raises a ValueError if x is a numpy array. It's an array of True/False values, not a single value.

Furthermore, numpy arrays can be indexed by boolean arrays. E.g. x[x>5] yields [6 7 8], in this case.

Honestly, it's fairly rare that you actually need numpy.where but it just returns the indicies where a boolean array is True. Usually you can do what you need with simple boolean indexing.

Assume I have below array:

Skins[
    {Id: 1, Name: "oily skin"}, 
    {Id: 2, Name: "dry skin"}
];

If we want to get item with Id = 1 and Name = "oily skin", We'll try as below:

var skinName = skins.find(x=>x.Id == "1").Name;

The result will return the skinName is "Oily skin".

I had a problem similar to the one posed in the original question. I was intrigued by the divs styled as table elements (didn't know you could do that!) and gave it a run. However, my solution was to keep my tables wrapped in tags, but rename each input and select option to become the keys of array, which I'm now parsing to get each element in the selected row.

Here's a single row from the table. Note that key [4] is the rendered ID of the row in the database from which this table row was retrieved:

<table>
  <tr>
    <td>DisabilityCategory</td>
    <td><input type="text" name="FormElem[4][ElemLabel]" value="Disabilities"></td>
    <td><select name="FormElem[4][Category]">
        <option value="1">General</option>
        <option value="3">Disability</option>
        <option value="4">Injury</option>
        <option value="2"selected>School</option>
        <option value="5">Veteran</option>
        <option value="10">Medical</option>
        <option value="9">Supports</option>
        <option value="7">Residential</option>
        <option value="8">Guardian</option>
        <option value="6">Criminal</option>
        <option value="11">Contacts</option>
      </select></td>
    <td>4</td>
    <td style="text-align:center;"><input type="text" name="FormElem[4][ElemSeq]" value="0" style="width:2.5em; text-align:center;"></td>
    <td>'ccpPartic'</td>
    <td><input type="text" name="FormElem[4][ElemType]" value="checkbox"></td>
    <td><input type="checkbox" name="FormElem[4][ElemRequired]"></td>
    <td><input type="text" name="FormElem[4][ElemLabelPrefix]" value=""></td>
    <td><input type="text" name="FormElem[4][ElemLabelPostfix]" value=""></td>
    <td><input type="text" name="FormElem[4][ElemLabelPosition]" value="before"></td>
    <td><input type="submit" name="submit[4]" value="Commit Changes"></td>
  </tr>
</table>

Then, in PHP, I'm using the following method to store in an array ($SelectedElem) each of the elements in the row corresponding to the submit button. I'm using print_r() just to illustrate:

$SelectedElem = implode(",", array_keys($_POST['submit']));
print_r ($_POST['FormElem'][$SelectedElem]);

Perhaps this sounds convoluted, but it turned out to be quite simple, and it preserved the organizational structure of the table.

You could do something like this:

i={'foo':'bar', 'baz':'huh?'}
keys=i.keys()  #in python 3, you'll need `list(i.keys())`
values=i.values()
print keys[values.index("bar")]  #'foo'

However, any time you change your dictionary, you'll need to update your keys,values because dictionaries are not ordered in versions of Python prior to 3.7. In these versions, any time you insert a new key/value pair, the order you thought you had goes away and is replaced by a new (more or less random) order. Therefore, asking for the index in a dictionary doesn't make sense.

As of Python 3.6, for the CPython implementation of Python, dictionaries remember the order of items inserted. As of Python 3.7+ dictionaries are ordered by order of insertion.

Also note that what you're asking is probably not what you actually want. There is no guarantee that the inverse mapping in a dictionary is unique. In other words, you could have the following dictionary:

d={'i':1, 'j':1}

In that case, it is impossible to know whether you want i or j and in fact no answer here will be able to tell you which ('i' or 'j') will be picked (again, because dictionaries are unordered). What do you want to happen in that situation? You could get a list of acceptable keys ... but I'm guessing your fundamental understanding of dictionaries isn't quite right.

You can define a context for your application say ExampleContext which will hold the context of your application and then use it to instantiate an activity like this:

var intent = new Intent(Application.ApplicationContext, typeof(Activity2));
intent.AddFlags(ActivityFlags.NewTask);
Application.ApplicationContext.StartActivity(intent);

Please bear in mind that this code is written in C# as I use MonoDroid, but I believe it is very similar to Java. For how to create an ApplicationContext look at this thread

This is how I made my Application Class

    [Application]
    public class Application : Android.App.Application, IApplication
    {
        public Application(IntPtr handle, JniHandleOwnership transfer) : base(handle, transfer)
        {

        }
        public object MyObject { get; set; }
    }

Yes, you can access it through GET and POST (trying this simple task would have made you aware of that).

Yes, there are other ways, one of the other "preferred" ways is using sessions. When you would want to use hidden over session is kind of touchy, but any GET / POST data is easily manipulated by the end user. A session is a bit more secure given it is saved to a file on the server and it is much harder for the end user to manipulate without access through the program.

First of all go to the device manager now go to View>>select Show hidden devices....Then go to network adapters and find out Microsoft Hosted network Virual Adapter ....Press right click and enable the option....

Then go to command prompt with administrative privileges and enter the following commands:

netsh wlan set hostednetwork mode=allow
netsh wlan start hostednetwork

Your Hostednetwork will work without any problems.

I met this issue due to operation system, simple to different platform about JRE implementation.

new SecureRandom(key.getBytes())

will get the same value in Windows, while it's different in Linux. So in Linux need to be changed to

SecureRandom secureRandom = SecureRandom.getInstance("SHA1PRNG");
secureRandom.setSeed(key.getBytes());
kgen.init(128, secureRandom);

"SHA1PRNG" is the algorithm used, you can refer here for more info about algorithms.

It means that $objPage is not an instance of an object. Can we see the code you used to initialize the variable?

As you expect a specific object type, you can also make use of PHPs type-hinting feature^Docs to get the error when your logic is violated:

function page_properties(PageAtrributes $objPortal) {    
    ...
    $objPage->set_page_title($myrow['title']);
}

This function will only accept PageAtrributes for the first parameter.

I would like to add that you can extend the compatibility of :scope by just assigning a temporary attribute to the current node.

let node = [...];
let result;

node.setAttribute("foo", "");
result = window.document.querySelectorAll("[foo] > .bar");
// And, of course, you can also use other combinators.
result = window.document.querySelectorAll("[foo] + .bar");
result = window.document.querySelectorAll("[foo] ~ .bar");
node.removeAttribute("foo");

If you are migrating to java7 or using java7 then generally this error can be seen. I faced above errors and struggled a lot to find out the root cause, I would suggest to try adding "-XX:-UseSplitVerifier" JVM argument while running your application.

You can disable them altogether by

(setq make-backup-files nil)

To be honest I don't know that you can. If you just set up a test instance and open Excel twice, because that is what you are talking about happening, if you name one workbook "test1" and another "test2" if you try to move a workbook, or even a worksheet between the two applications they are totally unaware of each other. I also notice odd behavior while simply manually cutting and pasting from Excel instance 1 and Excel instance 2.

You may have to write two macros kind of a drop off and then a pick up from a location that you share between them. Maybe a command button on the tool bar.

Maybe one of the super excel guys on here have a better answer.

As the other answers state:

• count will perform an SQL COUNT query
• length will calculate the length of the resulting array
• size will try to pick the most appropriate of the two to avoid excessive queries

But there is one more thing. We noticed a case where size acts differently to count/lengthaltogether, and I thought I'd share it since it is rare enough to be overlooked.

• If you use a :counter_cache on a has_many association, size will use the cached count directly, and not make an extra query at all.

  class Image < ActiveRecord::Base
    belongs_to :product, counter_cache: true
  end
  
  class Product < ActiveRecord::Base
    has_many :images
  end
  
  > product = Product.first  # query, load product into memory
  > product.images.size      # no query, reads the :images_count column
  > product.images.count     # query, SQL COUNT
  > product.images.length    # query, loads images into memory
  

This behaviour is documented in the Rails Guides, but I either missed it the first time or forgot about it.

I recently ran into a problem with a UICommand not invoking in a JSF 1.2 application using IBM Extended Faces Components.

I had a command button on a row of a datatable (the extended version, so <hx:datatable>) and the UICommand would not fire from certain rows from the table (the rows that would not fire were the rows greater than the default row display size).

I had a drop-down component for selecting number of rows to display. The value backing this field was in RequestScope. The data backing the table itself was in a sort of ViewScope (in reality, temporarily in SessionScope).

If the row display was increased via the control which value was also bound to the datatable's rows attribute, none of the rows displayed as a result of this change could fire the UICommand when clicked.

Placing this attribute in the same scope as the table data itself fixed the problem.

I think this is alluded to in BalusC #4 above, but not only did the table value need to be View or Session scoped but also the attribute controlling the number of rows to display on that table.

Adding;

display: inline-block;

to the child elements will prevent them being split between columns.

curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). The default bundle is named curl-ca-bundle.crt; you can specify an alternate file using the --cacert option.

If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL).

If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option.

for example

curl --insecure http://........

You could use the LINQ select clause and reference the property that relates to your Name column.

I've experienced a problem with length of None, which leads to Internal Server Error: TypeError: object of type 'NoneType' has no len()

My workaround is just displaying 0 if object is None and calculate length of other types, like list in my case:

{{'0' if linked_contacts == None else linked_contacts|length}}

For clear frame, first need to destroy all widgets inside the frame,. it will clear frame.

import tkinter as tk
from tkinter import *
root = tk.Tk()

frame = Frame(root)
frame.pack(side="top", expand=True, fill="both")

lab = Label(frame, text="hiiii")
lab.grid(row=0, column=0, padx=10, pady=5)

def clearFrame():
    # destroy all widgets from frame
    for widget in frame.winfo_children():
       widget.destroy()
    
    # this will clear frame and frame will be empty
    # if you want to hide the empty panel then
    frame.pack_forget()

frame.but = Button(frame, text="clear frame", command=clearFrame)
frame.but.grid(row=0, column=1, padx=10, pady=5)

# then whenever you add data in frame then you can show that frame
lab2 = Label(frame, text="hiiii")
lab2.grid(row=1, column=0, padx=10, pady=5)
frame.pack()
root.mainloop()

Another solutions is - Backing Up and Restoring Database

Back Up the System Database

To back up the system database using Microsoft SQL Server Management Studio Express, follow the steps below:

1. Download and install Microsoft SQL Server 2008 Management Studio Express from the Microsoft web site: http://www.microsoft.com/en-us/download/details.aspx?id=7593

2. After Microsoft SQL Server Management Studio Express has been installed, launch the application to connect to the system database. The "Connect to Server" dialog box displays. In the "Server name:" field, enter the name of the Webtrends server on which the system database is installed. In the "Authentication:" field select "Windows Authentication" if logged into the Windows machine using the Webtrends service account or an account with rights to make changes to the system database. Otherwise, select "SQL Server Authentication" from the drop-down menu and enter the credentials for a SQL Server account which has the needed rights. Click "Connect" to connect to the database.

3. Expand "Databases", right-click on "wt_sched" and select "Tasks" > "Back Up..." from the context menu. The "Back Up Database" dialog box displays. Under the "Source" section, ensure the "wt_sched" is selected for the "Database:" and "Backup type:" is "Full." Under "Backup set" provide a name, description and expiration date as needed and then select "Add..." under the "Destination" section and designate the file name and path where the backup will be saved. It may be necessary to select the "Overwrite all existing backup sets" option in the Options section if a backup already exists and is to be overwritten.

4. Select "OK" to complete the backup process.

5. Repeat the above steps for the "wtMaster" part of the database.

Restore the System Database

To restore the system database using Microsoft SQL Server Management Studio, follow the steps below:

1. If you haven't already, download and install Microsoft SQL Server 2008 Management Studio Express from the Microsoft web site: http://www.microsoft.com/en-us/download/details.aspx?id=7593

2. After Microsoft SQL Server Management Studio has been installed, launch the application to connect to the system database. The "Connect to Server" dialog box displays. In the "Server type:" field, select "Database Engine" (default). In the "Server name:" field, select "\WTSYSTEMDB" where is the name of the Webtrends server where the database is located. WTSYSTEMDB is the name of the database instance in a default installation. In the "Authentication:" field select "Windows Authentication" if logged into the Windows machine using the Webtrends service account or an account with rights to make changes to the system database. Otherwise, select "SQL Server Authentication" from the drop-down menu and enter the credentials for a SQL Server account which has the needed rights. Click "Connect" to connect to the database.

3. Expand "Databases", right-click on "wt_sched" and select "Delete" from the context menu. Make sure "Delete backup and restore history information for databases" check-box is checked.

4. Select "OK" to complete the deletion process.

5. Repeat the above steps for the "wtMaster" part of the database.

6. Right click on "Databases" and select "Restore Database..." from the context menu. In the "To database:" field type in "wt_sched". Select the "From device:" radio button. Click on the ellipse (...) to the right of the "From device:" text field. Click the "Add" button. Navigate to and select the backup file for "wt_sched". Select "OK" on the "Locate Backup File" form. Select "OK" on the "Specify Backup" form. Check the check-box in the restore column next to "wt_sched-Full Database Backup". Select "OK" on the "Restore Database" form.

7. Repeat step 6 for the "wtMaster" part of the database.

Steps:

1. Create a dataframe
2. Create a function
3. Use the named arguments of the function in the apply statement.

Example

x=pd.DataFrame([1,2,3,4])  

def add(i1, i2):  
    return i1+i2

x.apply(add,i2=9)

The outcome of this example is that each number in the dataframe will be added to the number 9.

    0
0  10
1  11
2  12
3  13

Explanation:

The "add" function has two parameters: i1, i2. The first parameter is going to be the value in data frame and the second is whatever we pass to the "apply" function. In this case, we are passing "9" to the apply function using the keyword argument "i2".

There are different approaches to refresh the current route

Change router behaviour (Since Angular 5.1) Set the routers onSameUrlNavigation to 'reload'. This will emit the router events on same URL Navigation.

• You can then handle them by subscribing to a route
• You can use it with the combination of runGuardsAndResolvers to rerun resolvers

Leave the router untouched

• Pass a refresh queryParam with the current timestamp in the URL and subscribe to queryParams in your routed component.
• Use the activate Event of the router-outlet to get a hold of the routed component.

I have written a more detailed explanation under https://medium.com/@kevinkreuzer/refresh-current-route-in-angular-512a19d58f6e

Hope this helps.

This also works:

REPLACE(ISNULL(CONVERT(DATE, @date), ''), '1900-01-01', '') AS 'Your Date Field'

I can't get it to work on $.get() because it has no complete event.

I suggest to use $.ajax() like this,

$.ajax({
    url: 'http://www.example.org',
    data: {'a':1,'b':2,'c':3},
    dataType: 'xml',
    complete : function(){
        alert(this.url)
    },
    success: function(xml){
    }
});

craz demo

The answer was already given, but I just want to give my piece of cake. What you want to achieve is called method borrowing in the context of JS, that when we take a method from an object and call it in the context of another object. It is quite common to take array methods and apply them to arguments. Let me give you an example.

So we have "super" hashing function which takes two numbers as an argument and returns "super safe" hashed string:

function hash() {
  return arguments[0]+','+arguments[1];
}

hash(1,2); // "1,2" whoaa

So far so good, but we have little problem with the above approach, it is constrained, only works with two numbers, that is not dynamic, let's make it work with any number and plus you do not have to pass an array (you can if you still insist). Ok, Enough talk, Let's fight!

The natural solution would be to use arr.join method:

function hash() {
  return arguments.join();
}

hash(1,2,4,..); //  Error: arguments.join is not a function

Oh, man. Unfortunately, that won’t work. Because we are calling hash(arguments) and arguments object is both iterable and array-like, but not a real array. How about the below approach?

function hash() {
  return [].join.call(arguments);
}

hash(1,2,3,4); // "1,2,3,4" whoaa

The trick is called method borrowing.

We borrow a join method from a regular array [].join. And use [].join.call to run it in the context of arguments.

Why does it work?

That’s because the internal algorithm of the native method arr.join(glue) is very simple.

Taken from the specification almost “as-is”:

Let glue be the first argument or, if no arguments, then a comma ",".
Let result be an empty string.
Append this[0] to result.
Append glue and this[1].
Append glue and this[2].
…Do so until this.length items are glued.
Return result.

So, technically it takes this and joins this[0], this[1] …etc together. It’s intentionally written in a way that allows any array-like this (not a coincidence, many methods follow this practice). That’s why it also works with this=arguments.

I like this one. Simple, and you can have more than one parameter for each argument:

final Map<String, List<String>> params = new HashMap<>();

List<String> options = null;
for (int i = 0; i < args.length; i++) {
    final String a = args[i];

    if (a.charAt(0) == '-') {
        if (a.length() < 2) {
            System.err.println("Error at argument " + a);
            return;
        }

        options = new ArrayList<>();
        params.put(a.substring(1), options);
    }
    else if (options != null) {
        options.add(a);
    }
    else {
        System.err.println("Illegal parameter usage");
        return;
    }
}

For example:

-arg1 1 2 --arg2 3 4

System.out.print(params.get("arg1").get(0)); // 1
System.out.print(params.get("arg1").get(1)); // 2
System.out.print(params.get("-arg2").get(0)); // 3
System.out.print(params.get("-arg2").get(1)); // 4

Use [NSIndexPath indexPathForRow:inSection:] to quickly create an index path.

Edit: In Swift 3:

let indexPath = IndexPath(row: rowIndex, section: sectionIndex)

Swift 5

IndexPath(row: 0, section: 0)

I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers.

The "Host" header field in a request provides the host and port
information from the target URI, enabling the origin server to
distinguish among resources while servicing requests for multiple
host names on a single IP address.

Just apply this style before applying any CSS. You can change width as per your need.

for react-router V5 and above use below syntax for multiple paths

<Route
          exact
          path={[path1, path2]}
          component={component}
        />

For me it was an issue with deviceToken. Please check if the receiver and sender device token is properly updated in your database or wherever you are accessing it to send notifications.

For instance, use the following to update the device token on app launch. Therefore it will be always updated properly.

// Device token for push notifications
FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(
  new OnSuccessListener<InstanceIdResult>() {

    @Override
    public void onSuccess(InstanceIdResult instanceIdResult) {

        deviceToken = instanceIdResult.getToken();

        // Insert device token into Firebase database
        fbDbRefRoot.child("user_detail_profile").child(currentUserId).child("device_token")).setValue(deviceToken)
                .addOnSuccessListener(
                  new OnSuccessListener<Void>() {

                    @Override
                    public void onSuccess(Void aVoid) {

                    }
                });
    }
});

If it happens when you try to install some package via composer just use this command COMPOSER_MEMORY_LIMIT=-1 composer require nameofpackage

You will have the duplicate values for name and price here. And ids are duplicate in the drinks_photos table.There is no way you can avoid them.Also what exactly you want the output ?

The following tested working

<iframe style="width:100%; height:100%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" src="index.html" frameborder="0" height="100%" width="100%"></iframe>

You are all wrong! Why? Because all you need is this code to work:

(image View) / C# Img is : your Image box

Keep this as is, without change ("ms-appx:///) this is code not your app name Images is your folder in your project you can change it. dog.png is your file in your folder, as well as i do my folder 'Images' and file 'dog.png' So the uri is :"ms-appx:///Images/dog.png" and my code :

private void Button_Click(object sender, RoutedEventArgs e)
    {
         img.Source = new BitmapImage(new Uri("ms-appx:///Images/dog.png"));
    }

The second thing i did was Uninstall my Anti-Virus software (AVG Antivirus) {sounds crazy but, i had to}. it reduced gradle build time upto 40%

The first thing i did was enable offline mode (1. click on Gradle usually on the right side of the editor 2. click on the connection button to toggle) it reduced the gradle build time for upto 20%

so my Gradle build time was reduced for upto 60% by doing these two things

This design was not mentioned yet:

Multiple lineage columns

Though it has limitations, if you can bear them, it's very simple and very efficient. Features:

• Columns: one for each lineage level, refers to all the parents up to the root, levels below the current items' level are set to 0 (or NULL)
• There is a fixed limit to how deep the hierarchy can be
• Cheap ancestors, descendants, level
• Cheap insert, delete, move of the leaves
• Expensive insert, delete, move of the internal nodes

Here follows an example - taxonomic tree of birds so the hierarchy is Class/Order/Family/Genus/Species - species is the lowest level, 1 row = 1 taxon (which corresponds to species in the case of the leaf nodes):

CREATE TABLE `taxons` (
  `TaxonId` smallint(6) NOT NULL default '0',
  `ClassId` smallint(6) default NULL,
  `OrderId` smallint(6) default NULL,
  `FamilyId` smallint(6) default NULL,
  `GenusId` smallint(6) default NULL,
  `Name` varchar(150) NOT NULL default ''
);

and the example of the data:

+---------+---------+---------+----------+---------+-------------------------------+
| TaxonId | ClassId | OrderId | FamilyId | GenusId | Name                          |
+---------+---------+---------+----------+---------+-------------------------------+

This is great because this way you accomplish all the needed operations in a very easy way, as long as the internal categories don't change their level in the tree.

import { HttpModule } from '@angular/http'; package in your module.ts file and add it in your imports.

You have to consider the Turkish I problem when comparing characters/ lowercasing / uppercasing:

I suggest to convert to String and use toLowerCase with invariant culture (in most cases at least).

public final static Locale InvariantLocale = new Locale(Empty, Empty, Empty); str.toLowerCase(InvariantLocale)

See similar C# string.ToLower() and string.ToLowerInvariant()

Note: Don't use String.equalsIgnoreCase http://nikolajlindberg.blogspot.co.il/2008/03/beware-of-java-comparing-turkish.html

FWIW, here is my approach = a simple one that works for me:

<div id="outerDivWrapper">
   <div id="outerDiv">
      <div id="scrollableContent">
blah blah blah
      </div>
   </div>
</div>

html, body {
   height: 100%;
   margin: 0em;
}

#outerDivWrapper, #outerDiv {
   height: 100%;
   margin: 0em;
}

#scrollableContent {
   height: 100%;
   margin: 0em;
   overflow-y: auto;
}

If only the column names are available like :

cnms <- c("Nam1","Nam2","Nam3")

To create an empty data frame with the above variable names, first create a data.frame object:

emptydf <- data.frame()

Now call zeroth element of every column, thus creating an empty data frame with the given variable names:

for( i in 1:length(cnms)){
     emptydf[0,eval(cnms[i])]
 }

• Virtual functions must have a definition in base class and also in derived class but not necessary, for example ToString() or toString() function is a Virtual so you can provide your own implementation by overriding it in user-defined class(es).

• Virtual functions are declared and defined in normal class.

• Pure virtual function must be declared ending with "= 0" and it can only be declared in abstract class.

• An abstract class having a pure virtual function(s) cannot have a definition(s) of that pure virtual functions, so it implies that implementation must be provided in class(es) that derived from that abstract class.

The answers here are outdated. Now you can easily use a CSS3 transform without hardcoding a margin. This works on all elements, including elements with no width or dynamic width.

Horizontal center:

left: 50%;
transform: translateX(-50%);

Vertical center:

top: 50%;
transform: translateY(-50%);

Both horizontal and vertical:

left: 50%;
top: 50%;
transform: translate(-50%, -50%);

Compatibility is not an issue: http://caniuse.com/#feat=transforms2d

It's possible to use TUN/TAP device. http://tuntaposx.sourceforge.net/

     android:layout_height="wrap_content"
     android:hint="Hiiiii"
     android:id="@+id/edit_id"/>


</android.support.design.widget.TextInputLayout>

In Styles Folder TextLabel Code

 <style name="TextLabel" parent="TextAppearance.AppCompat">
<!-- Hint color and label color in FALSE state -->
<item name="android:textColorHint">@color/Color Name</item> 
<item name="android:textSize">20sp</item>

The DELIMITER statement changes the standard delimiter which is semicolon ( ;) to another. The delimiter is changed from the semicolon( ;) to double-slashes //.

Why do we have to change the delimiter?

Because we want to pass the stored procedure, custom functions etc. to the server as a whole rather than letting mysql tool to interpret each statement at a time.

It also happens when apple developer account expires for stopped payment. The old cert may be still usable to debug breakpoint for a week or few. Then one day all the sudden debug stepping on iPhone devices will be denied.

The solution is re-generate cert after paying for developer account. It may take some hours to get activated by apple.

Remember to delete old certs(ios dev, apple worldwide,) in keychain app of your mac. Revoke old cert in apple developer website optionally for cleanup. And create new one (with xcode directly is also fine) That will enable iphone debug.

After looking at sp_who, Oracle does not have that ability per se. Oracle has at least 8 processes running which run the db. Like RMON etc.

You can ask the DB which queries are running as that just a table query. Look at the V$ tables.

Quick Example:

SELECT sid,
       opname,
       sofar,
       totalwork,
       units,
       elapsed_seconds,
       time_remaining
FROM v$session_longops
WHERE sofar != totalwork;

$("#dialog").dialog({
    autoOpen: false,
    resizable: false,

        "SUBMIT": function() { 
        $("form").submit();
    }, 
        "CANCEL": function() { 
        $(this).dialog("close");
    } 
    },
    close: function() {
      alert('close');
    }
});

Did you try something like:

In my case it was a failed import to eclipse. I had to delete the project from eclipse (without deleting form the filesystem of course) and reimport it. After that the error was gone immediately.

Add a class as Public and use it very easily like convertToInt32()

  using System;
  using System.Collections.Generic;
  using System.Linq;
  using System.Web;

  /// <summary>
  /// Summary description for Common
  /// </summary>
  public static class Common
  {
     public static double ConvertToDouble(string Value) {
        if (Value == null) {
           return 0;
        }
        else {
           double OutVal;
           double.TryParse(Value, out OutVal);

           if (double.IsNaN(OutVal) || double.IsInfinity(OutVal)) {
              return 0;
           }
           return OutVal;
        }
     }
  }

Then Call The Function

double DirectExpense =  Common.ConvertToDouble(dr["DrAmount"].ToString());

I think you can remove all your log with switch from full to simple recovery. Right click on your Database and select Properties and select Options and change

The problem is in your "this" value. Timer function cannot access the "state" prop because run in a different context. I suggest you to do something like this:

...
startTimer = () => {
  let interval = setInterval(this.timer.bind(this), 1000);
  this.setState({ interval });
};

As you can see I've added a "bind" method to your timer function. This allows the timer, when called, to access the same "this" of your react component (This is the primary problem/improvement when working with javascript in general).

Another option is to use another arrow function:

startTimer = () => {
  let interval = setInterval(() => this.timer(), 1000);
  this.setState({ interval });
};

I read this post Why String is Immutable or Final in Java and suppose that following may be the most important reason:

String is Immutable in Java because String objects are cached in String pool. Since cached String literals are shared between multiple clients there is always a risk, where one client's action would affect all another client.

In most browsers, the title attribute will render as a tooltip, and is generally flexible as to what sorts of elements it'll work with.

<span title="This will show as a tooltip">Mouse over for a tooltip!</span>
<a href="http://www.stackoverflow.com" title="Link to stackoverflow.com">stackoverflow.com</a>
<img src="something.png" alt="Something" title="Something">

All of those will render tooltips in most every browser.

Here I am giving you a proper example of one callback method . so suppose we have a method like method login() :

 public void login() {
    loginService = new LoginService();
    loginService.login(loginProvider, new LoginListener() {
        @Override
        public void onLoginSuccess() {
            loginService.getresult(true);
        }

        @Override
        public void onLoginFaliure() {
            loginService.getresult(false);

        }
    });
    System.out.print("@@##### get called");
}

I also put all the helper class here to make the example more clear: loginService class

public class LoginService implements Login.getresult{
public void login(LoginProvider loginProvider,LoginListener callback){

    String username  = loginProvider.getUsername();
    String pwd  = loginProvider.getPassword();
    if(username != null && pwd != null){
        callback.onLoginSuccess();
    }else{
        callback.onLoginFaliure();
    }

}

@Override
public void getresult(boolean value) {
    System.out.print("login success"+value);
}}

and we have listener LoginListener as :

interface LoginListener {
void onLoginSuccess();

void onLoginFaliure();

}

now I just wanted to test the method login() of class Login

 @Test
public void loginTest() throws Exception {
    LoginService service = mock(LoginService.class);
    LoginProvider provider = mock(LoginProvider.class);
    whenNew(LoginProvider.class).withNoArguments().thenReturn(provider);
    whenNew(LoginService.class).withNoArguments().thenReturn(service);
    when(provider.getPassword()).thenReturn("pwd");
    when(provider.getUsername()).thenReturn("username");
    login.getLoginDetail("username","password");

    verify(provider).setPassword("password");
    verify(provider).setUsername("username");

    verify(service).login(eq(provider),captor.capture());

    LoginListener listener = captor.getValue();

    listener.onLoginSuccess();

    verify(service).getresult(true);

also dont forget to add annotation above the test class as

@RunWith(PowerMockRunner.class)
@PrepareForTest(Login.class)

I have a similar question here: Writting in sub-ndarray of a ndarray in the most pythonian way. Python 2 .

Following the solution of previous post for your case the solution looks like:

columns_to_keep = [1,3] 
rows_to_keep = [1,3]

An using ix_:

x[np.ix_(rows_to_keep, columns_to_keep)] 

Which is:

array([[ 5,  7],
       [13, 15]])

If you want to do it the dirty way, try this.

@SuppressWarnings("unchecked")
public ArrayList<String> convert(ArrayList<Object> a) {
   return (ArrayList) a;
}

Advantage: here you save time by not iterating over all objects.

Disadvantage: may produce a hole in your foot.

You could use an immutable struct

public struct Data
{
    public Data(int intValue, string strValue)
    {
        IntegerData = intValue;
        StringData = strValue;
    }

    public int IntegerData { get; private set; }
    public string StringData { get; private set; }
}

var list = new List<Data>();

Or a KeyValuePair<int, string>

using Data = System.Collections.Generic.KeyValuePair<int, string>
...
var list = new List<Data>();
list.Add(new Data(12345, "56789"));

Running the command below worked with. Tried changing server.xml and the conf file but both didn't work.

/sbin/iptables -A INPUT -i eth0 -p tcp --dport 80 -j ACCEPT

/sbin/iptables -A INPUT -i eth0 -p tcp --dport 8080 -j ACCEPT

/sbin/iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080

Nothing wrong with your method, it's a G-mail security issue.

1. Login g-mail account settings.

2. Enable 2-step verification.

3. Generate app-password.

4. Use new-generated password in place of your real g-mail password.

Don't forget to clear cache.

php artisan config:cache.
php artisan config:clear.

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=generatedAppPassword
MAIL_ENCRYPTION=tls

Use Timer and tick event to copy your files.

On start the service, start the time and specify the interval in the time.

So the service is keep running and copy the files ontick.

Hope it help.

Your code was compiled with Java Version 1.8 while it is being executed with Java Version 1.7 or below.

In your case it seems that two different Java installations are used, the newer to compile and the older to execute your code.

Try recompiling your code with Java 1.7 or upgrade your Java Plugin.

No need to trying reinvent the wheel, as this is common greatest-n-per-group problem. Very nice solution is presented.

I prefer the most simplistic solution (see SQLFiddle, updated Justin's) without subqueries (thus easy to use in views):

SELECT t1.*
FROM lms_attendance AS t1
LEFT OUTER JOIN lms_attendance AS t2
  ON t1.user = t2.user 
        AND (t1.time < t2.time 
         OR (t1.time = t2.time AND t1.Id < t2.Id))
WHERE t2.user IS NULL

This also works in a case where there are two different records with the same greatest value within the same group - thanks to the trick with (t1.time = t2.time AND t1.Id < t2.Id). All I am doing here is to assure that in case when two records of the same user have same time only one is chosen. Doesn't actually matter if the criteria is Id or something else - basically any criteria that is guaranteed to be unique would make the job here.

As a variation of Bridge's answer (I don't yet have enough rep to comment, and didn't feel right about editing that answer), here is a version that works better for me.

SELECT column_name AS [Name],
   IS_NULLABLE AS [Null?],
   DATA_TYPE + CASE
                 WHEN CHARACTER_MAXIMUM_LENGTH IS NULL THEN ''
                 WHEN CHARACTER_MAXIMUM_LENGTH > 99999 THEN ''
                 ELSE '(' + Cast(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5)) + ')' 
               END AS [Type]
FROM   INFORMATION_SCHEMA.Columns
WHERE  table_name = 'table_name'

Notable changes:

• Works for types without length. For an int column, I was seeing NULL for the type because the length was null and it wiped out the whole Type column. So don't print any length component (or parens).
• Change the check for CAST length of -1 to check actual length. I was getting a syntax error because the case resulted in '*' rather than -1. Seems to make more sense to perform an arithmetic check rather than an overflow from the CAST.
• Don't print length when very long (arbitrarily > 5 digits).

m.str("");

seems to work.

We can create a for loop and pass all the numeric columns into it. The loop will plot the graphs one by one in separate pane as we are including plt.figure() into it.

import pandas as pd
import seaborn as sns
import numpy as np

numeric_features=[x for x in data.columns if data[x].dtype!="object"]
#taking only the numeric columns from the dataframe.

for i in data[numeric_features].columns:

    plt.title(i)
    sns.boxplot(data=data[i])

Not mention so far and an update, there is a very well establish library for handling paths that are too long. AlphaFS is a .NET library providing more complete Win32 file system functionality to the .NET platform than the standard System.IO classes. The most notable deficiency of the standard .NET System.IO is the lack of support of advanced NTFS features, most notably extended length path support (eg. file/directory paths longer than 260 characters).

Note that if you use rocket_r it will reverse the colors and somehow it looks more natural and better such as below:

Hashes are a sequence of bits (128 bits, 160 bits, 256 bits, etc., depending on the algorithm). Your column should be binary-typed, not text/character-typed, if MySQL allows it (SQL Server datatype is binary(n) or varbinary(n)). You should also salt the hashes. Salts may be text or binary, and you will need a corresponding column.

Not in Linux at the moment, so can't double check, but I think it's:

rpm -ql ffmpeg

That should list all the files installed as part of the ffmpeg package.

We can also create the object in this way:-

String s ="Hello";

Nobody has discuss it.

this function takes the number and precision and returns the rounded off number

float roundoff(float num,int precision)
{
      int temp=(int )(num*pow(10,precision));
      int num1=num*pow(10,precision+1);
      temp*=10;
      temp+=5;
      if(num1>=temp)
              num1+=10;
      num1/=10;
      num1*=10;
      num=num1/pow(10,precision+1);
      return num;
}

it converts the floating point number into int by left shifting the point and checking for the greater than five condition.

For me the /**<NEWLINE> or Shift-Alt-J (or ?-?-J on a Mac) approach works best.

I dislike seeing Javadoc comments in source code that have been auto-generated and have not been updated with real content. As far as I am concerned, such javadocs are nothing more than a waste of screen space.

IMO, it is much much better to generate the Javadoc comment skeletons one by one as you are about to fill in the details.

is occurring because the current SDK version is incompatible with Java 9.

So, to solve it, you can downgrade your java version to Java 8, or with a workaround, you can export the following option on your terminal:

Linux:

export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

Windows:

set JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'

And to make it stick, you can export the JAVA_OPTS in your profile file on Linux (.zshrc, .bashrc and etc.) or add as an environment permanently on Windows.

Then, you can type the flutter or sdkmanager command:

Flutter:

flutter doctor --android-licenses

sdkmanager:

sdkmanager --licenses

and type Y when needed to accept the licenses.

ps. This doesn't work for Java 11/11+, which doesn't have Java EE modules. For this option is a good idea, downgrade your Java version or wait for a Flutter update.

Before stumbling onto this post, I came up with this solution - to toggle the TopMost property:

this.TopMost = true;
this.TopMost = false;

I have this code in my form's constructor, eg:

public MyForm()
{
    //...

    // Brint-to-front hack
    this.TopMost = true;
    this.TopMost = false;

    //...
}

Java, unlike languages like C and C++, treats boolean as a completely separate data type which has 2 distinct values: true and false. The values 1 and 0 are of type int and are not implicitly convertible to boolean.

you are thinking too much... Take a look at this [i think this is what you wanted - if not let me know]

For anyone still reading this: setTargetFragment() has been deprecated. It is now recommended to use the FragmentResultListener API like this:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setFragmentResultListener("requestKey") { key, bundle ->
        val result = bundle.getString("resultKey")
        // Do something with the result...
    }

    ...

    // Somewhere show your dialog
    MyDialogFragment.newInstance().show(parentFragmentManager, "tag")
}

Then in your MyDialogFragment set the result:

button.setOnClickListener{
    val result = "some string"
    setFragmentResult("requestKey", bundleOf("resultKey" to result))
    dismiss()
}

If you are using Eclipse, for an existing project (which has a build.gradle file) you can simply type gradle eclipse which will create all the Eclipse files and folders for this project.

It takes care of all the dependencies for you and adds them to the project resource path in Eclipse as well.

Yes it can be done. You need to use

position:absolute;
left:0;
right:0;

Check working example at http://jsfiddle.net/bJbgJ/3/

I think the most intuitive way to do this is by giving the children a "wait" prop, which hides the component for the duration that was passed down from the parent. By setting the default state to hidden, React will still render the component immediately, but it won't be visible until the state has changed. Then, you can set up componentWillMount to call a function to show it after the duration that was passed via props.

var Child = React.createClass({
    getInitialState : function () {
        return({hidden : "hidden"});
    },
    componentWillMount : function () {
        var that = this;
        setTimeout(function() {
            that.show();
        }, that.props.wait);
    },
    show : function () {
        this.setState({hidden : ""});
    },
    render : function () {
        return (
            <div className={this.state.hidden}>
                <p>Child</p>
            </div>
        )
    }
});

Then, in the Parent component, all you would need to do is pass the duration you want a Child to wait before displaying it.

var Parent = React.createClass({
    render : function () {
        return (
            <div className="parent">
                <p>Parent</p>
                <div className="child-list">
                    <Child wait={1000} />
                    <Child wait={3000} />
                    <Child wait={5000} />
                </div>
            </div>
        )
    }
});

Here's a demo

I use from selenium-java-3.141.59 in windows 10 and solved my problem with this code:

System.setProperty("webdriver.gecko.driver", "C:\\gecko\\geckodriver.exe");
System.setProperty("webdriver.firefox.bin","C:\\Program Files\\Mozilla Firefox\\firefox.exe");
WebDriver driver = new FirefoxDriver();

• rgb(255, 255, 255) // returns FFFFFF

• rgb(255, 255, 300) // returns FFFFFF

• rgb(0,0,0) // returns 000000

• rgb(148, 0, 211) // returns 9400D3

   function rgb(...values){
            return values.reduce((acc, cur) => {
              let val = cur >= 255 ? 'ff' : cur <= 0 ? '00' : Number(cur).toString(16);
              return acc + (val.length === 1 ? '0'+val : val);
            }, '').toUpperCase();
        }
  

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

There are two steps here:

• Parse the data. Your example is not fully reproducible, is the data in a file, or the variable in a text or factor variable? Let us assume the latter, then if you data.frame is called X, you can do

 X$newdate <- strptime(as.character(X$date), "%d/%m/%Y")

Now the newdate column should be of type Date.

• Format the data. That is a matter of calling format() or strftime():

 format(X$newdate, "%Y-%m-%d")

A more complete example:

R> nzd <- data.frame(date=c("31/08/2011", "31/07/2011", "30/06/2011"), 
+                    mid=c(0.8378,0.8457,0.8147))
R> nzd
        date    mid
1 31/08/2011 0.8378
2 31/07/2011 0.8457
3 30/06/2011 0.8147
R> nzd$newdate <- strptime(as.character(nzd$date), "%d/%m/%Y")
R> nzd$txtdate <- format(nzd$newdate, "%Y-%m-%d")
R> nzd
        date    mid    newdate    txtdate
1 31/08/2011 0.8378 2011-08-31 2011-08-31
2 31/07/2011 0.8457 2011-07-31 2011-07-31
3 30/06/2011 0.8147 2011-06-30 2011-06-30
R> 

The difference between columns three and four is the type: newdate is of class Date whereas txtdate is character.

I recently hit the same error. Some digging brought up this: http://support.microsoft.com/kb/815645

Basically, if you have spaces in the path of the .lib, that's bad. Don't know if that's what's happening for you, but seems reasonably possible.

The fix is either 1) put the lib reference in "quotes", or 2) add the lib's path to your Library Directories (Configuration Properties >> VC++ Directories).

It has been done there : http://www.jezra.net/projects/pageplayer

Add a width to the .child elements. I personally would use percentages on the margin-left if you want to have it always 4 per row.

DEMO

.child {
    display: inline-block;
    background: blue;
    margin: 10px 0 0 2%;
    flex-grow: 1;
    height: 100px;
    width: calc(100% * (1/4) - 10px - 1px);
}

heres a DOM solution

myInput=document.getElementById("myinput");
oldHtml=myInput.outerHTML;
text=myInput.value;
newHtml=oldHtml.replace("password","text");
myInput.outerHTML=newHtml;
myInput=document.getElementById("myinput");
myInput.value=text;

Try this:

select col1, col2, 'ABC' as col3 from Table1 where col1 = 0;

from openpyxl import load_workbook

sheets = load_workbook(excel_file, read_only=True).sheetnames

For a 5MB Excel file I'm working with, load_workbook without the read_only flag took 8.24s. With the read_only flag it only took 39.6 ms. If you still want to use an Excel library and not drop to an xml solution, that's much faster than the methods that parse the whole file.

I had major trouble getting this to work in RCx releases of angular2. The Location package has moved, and running location.go() inside constructor() wont work. It needs to be ngOnInit() or later in the lifecycle. Here is some example code:

import {OnInit} from '@angular/core';
import {Location} from '@angular/common';

@Component({
  selector: 'example-component',
  templateUrl: 'xxx.html'
})
export class ExampleComponent implements OnInit
{
  constructor( private location: Location )
  {}

  ngOnInit()
  {    
    this.location.go( '/example;example_param=917' );
  }
}

Here are the angular resources on the matter: https://angular.io/docs/ts/latest/api/common/index/Location-class.html https://angular.io/docs/ts/latest/api/common/index/LocationStrategy-class.html
