This is from my own library, will return the difference of months between two dates.

public static int MonthDiff(DateTime d1, DateTime d2)
{
    int retVal = 0;

    // Calculate the number of years represented and multiply by 12
    // Substract the month number from the total
    // Substract the difference of the second month and 12 from the total
    retVal = (d1.Year - d2.Year) * 12;
    retVal = retVal - d1.Month;
    retVal = retVal - (12 - d2.Month);

    return retVal;
}

Cursors tend to be used by beginning SQL developers in places where set-based operations would be better. Particularly when people learn SQL after learning a traditional programming language, the "iterate over these records" mentality tends to lead people to use cursors inappropriately.

Most serious SQL books include a chapter enjoining the use of cursors; well-written ones make it clear that cursors have their place but shouldn't be used for set-based operations.

There are obviously situations where cursors are the correct choice, or at least A correct choice.

just select '0' as the value for the desired column

If you want to open it for a range and for a protocol

ufw allow 11200:11299/tcp
ufw allow 11200:11299/udp

var name = $('#myElement').attr('name');

Correct Xpath syntax is like:

//tagname[@value='name']

So you should write something like this:

findElement(By.xpath("//input[@test-id='test-username']"));

Use this code to setup your mongodb connection:

var mongoose = require('mongoose');

var mongoURI = "mongodb://localhost:27017/test";
var MongoDB = mongoose.connect(mongoURI).connection;
MongoDB.on('error', function(err) { console.log(err.message); });
MongoDB.once('open', function() {
  console.log("mongodb connection open");
});

Make sure mongod is running while you start the server. Are you using Express or just a simple node.js server? What is the error message you get with the above code?

Try removing the float attribute from span6:

{ float:none !important; }

Technically the answer of zlovelady is preferable, but as I had only to remove items from the navigation, the approach of unsetting the not-needed navigation items in the template was the fastest/easiest way for me:

Just duplicate

app/design/frontend/base/default/template/customer/account/navigation

to

app/design/frontend/YOUR_THEME/default/template/customer/account/navigation

and unset the unneeded navigation items before the get rendered, e.g.:

<?php $_links = $this->getLinks(); ?>    
<?php 
    unset($_links['recurring_profiles']);
?>

The dir you specified is a working directory of running process - it doesn't help to find executable. Use cmd /c winrar ... to run process looking for executable in PATH or try to use absolute path to winrar.

grep -n "YOUR SEARCH STRING" * > output-file

The -n will print the line number and the > will redirect grep-results to the output-file.
If you want to "clean" the results you can filter them using pipe | for example:
grep -n "test" * | grep -v "mytest" > output-file will match all the lines that have the string "test" except the lines that match the string "mytest" (that's the switch -v) - and will redirect the result to an output file.
A few good grep-tips can be found on this post

with open('dump.sql', 'w') as f:

ANSWER: <embed src="https://YOURDOMAIN.com/PAGE.HTM" style="width:100%; height: 50vw;">

I always prefer to use mixins for small CSS classes like fade in / out incase you want to use them in more than one class.

@mixin fade-in {
    opacity: 1;
    animation-name: fadeInOpacity;
    animation-iteration-count: 1;
    animation-timing-function: ease-in;
    animation-duration: 2s;
}

@keyframes fadeInOpacity {
    0% {
        opacity: 0;
    }
    100% {
        opacity: 1;
    }
}

and if you don't want to use mixins, you can create a normal class .fade-in.

I know this post is old but I just wanted to add my answer!

You said to log a user out WITHOUT directing... this method DOES redirect but it returns the user to the page they were on! here's my implementation:

// every page with logout button
<?php
        // get the full url of current page
        $page = $_SERVER['PHP_SELF'];
        // find position of the last '/'
        $file_name_begin_pos = strripos($page, "/");
        // get substring from position to end 
        $file_name = substr($page, ++$fileNamePos);
    }
?>

// the logout link in your html
<a href="logout.php?redirect_to=<?=$file_name?>">Log Out</a>

// logout.php page
<?php
    session_start();
    $_SESSION = array();
    session_destroy();
    $page = "index.php";
    if(isset($_GET["redirect_to"])){
        $file = $_GET["redirect_to"];
        if ($file == "user.php"){
            // if redirect to is a restricted page, redirect to index
            $file = "index.php";
        }
    }
    header("Location: $file");
?>

and there we go!

the code that gets the file name from the full url isn't bug proof. for example if query strings are involved with un-escaped '/' in them, it will fail.

However there are many scripts out there to get the filename from url!

Happy Coding!

You can do this using a group by:

select id, addressCode
from t
group by id, addressCode
having min(address) <> max(address)

Another way of writing this may seem clearer, but does not perform as well:

select id, addressCode
from t
group by id, addressCode
having count(distinct address) > 1

The difference is in which lock is being acquired:

• synchronized method acquires a lock on the whole object. This means no other thread can use any synchronized method in the whole object while the method is being run by one thread.

• synchronized blocks acquires a lock in the object between parentheses after the synchronized keyword. Meaning no other thread can acquire a lock on the locked object until the synchronized block exits.

So if you want to lock the whole object, use a synchronized method. If you want to keep other parts of the object accessible to other threads, use synchronized block.

If you choose the locked object carefully, synchronized blocks will lead to less contention, because the whole object/class is not blocked.

This applies similarly to static methods: a synchronized static method will acquire a lock in the whole class object, while a synchronized block inside a static method will acquire a lock in the object between parentheses.

Encountering the same problem, I solved this by reconverting the file with default mp4 settings in iMovie.

With map (not as good, but another approach to the problem):

list(map(lambda x: x*5,[5, 10, 15, 20, 25]))

also, if you happen to be using numpy or numpy arrays, you could use this:

import numpy as np
list(np.array(x) * 5)

Prior to ECMAScript 5, parseInt() also autodetected octal literals, which caused problems because many developers assumed a leading 0 would be ignored.

So Instead of :

var num = parseInt("071");      // 57

Do this:

var num = parseInt("071", 10);  // 71

var num = parseInt("071", 8);

var num = parseFloat(someValue); 

Reference

I was getting this error today and couldn't work it out for a while, but I realised it was after adding some RequireAttributes to my models and that some development seed data was not populating all of the required fields.
So just a note that if you're getting this error whilst updating the database through some sort of init strategy like DropCreateDatabaseIfModelChanges then you have to make sure that your seed data fulfils and satisfies any model data validation attributes.

I know this is slightly different to the problem in the question, but it's a popular question so I thought I'd add a bit more to the answer for others having the same issue as myself.
Hope this helps others :)

Something like this should work.

System.Net.WebClient

public static bool CheckForInternetConnection()
{
    try
    {
        using (var client = new WebClient())
            using (client.OpenRead("http://google.com/generate_204")) 
                return true; 
    }
    catch
    {
        return false;
    }
}

The jQuery answer was pretty useful to me. With a little refactory it fitted my needs well. I hope it helps anybody else.

function onReady ( callback ){
    var addListener = document.addEventListener || document.attachEvent,
        removeListener =  document.removeEventListener || document.detachEvent
        eventName = document.addEventListener ? "DOMContentLoaded" : "onreadystatechange"

    addListener.call(document, eventName, function(){
        removeListener( eventName, arguments.callee, false )
        callback()
    }, false )
}

And don't forget to create a __init__.py with each folder/subfolder (even if they are empty)

A trick I often use when I just need "a little" shadow (read: contour must not be super-precise) is placing a DIV with a radial fill 100%-black-to-100%-transparent under the image. The CSS for the DIV looks something like:

.shadow320x320{    
        background: -moz-radial-gradient(center, ellipse cover, rgba(0,0,0,0.58) 0%, rgba(0,0,0,0.58) 1%, rgba(0,0,0,0) 43%, rgba(0,0,0,0) 100%); /* FF3.6+ */
        background: -webkit-gradient(radial, center center, 0px, center center, 100%, color-stop(0%,rgba(0,0,0,0.58)), color-stop(1%,rgba(0,0,0,0.58)), color-stop(43%,rgba(0,0,0,0)), color-stop(100%,rgba(0,0,0,0))); /* Chrome,Safari4+ */
        background: -webkit-radial-gradient(center, ellipse cover, rgba(0,0,0,0.58) 0%,rgba(0,0,0,0.58) 1%,rgba(0,0,0,0) 43%,rgba(0,0,0,0) 100%); /* Chrome10+,Safari5.1+ */
        background: -o-radial-gradient(center, ellipse cover, rgba(0,0,0,0.58) 0%,rgba(0,0,0,0.58) 1%,rgba(0,0,0,0) 43%,rgba(0,0,0,0) 100%); /* Opera 12+ */
        background: -ms-radial-gradient(center, ellipse cover, rgba(0,0,0,0.58) 0%,rgba(0,0,0,0.58) 1%,rgba(0,0,0,0) 43%,rgba(0,0,0,0) 100%); /* IE10+ */
        background: radial-gradient(ellipse at center, rgba(0,0,0,0.58) 0%,rgba(0,0,0,0.58) 1%,rgba(0,0,0,0) 43%,rgba(0,0,0,0) 100%); /* W3C */
        filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#94000000', endColorstr='#00000000',GradientType=1 ); /* IE6-9 fallback on horizontal gradient */
  }

This will create a circular black faded-out 'dot' on a 320x320 DIV. If you scale the height or width of the DIV you get a corresponding oval. Very nice to create eg shadows under bottles or other cylinder-like shapes.

There is an absolute incredible, super-excellent tool to create CSS gradients here:

http://www.colorzilla.com/gradient-editor/

ps: Do a courtesy ad-click when you use it. (And, no,I'm not affiliated with it. But courtesy clicking should become a bit of a habit, especially for tool you use often... just sayin... since we're all working on the net...)

use the min-height property. min-height:20px;

@ Original Poster - see inline comments.

public class demo 
{
    public static void main(String a[]) 
    {
        B b = (B) new A(); // compiles with the cast, but runtime exception - java.lang.ClassCastException 
        //- A subclass variable cannot hold a reference to a superclass  variable. so, the above statement will not work.

        //For downcast, what you need is a superclass ref containing a subclass object.
        A superClassRef = new B();//just for the sake of illustration
        B subClassRef = (B)superClassRef; // Valid downcast. 
    }
}

class A

    public void draw() 
    {
        System.out.println("1");
    }

    public void draw1() 
    {
        System.out.println("2");
    }
}

class B extends A 
{
    public void draw() 
    {
        System.out.println("3");

    public void draw2() 
    {
        System.out.println("4");

Most updated:

$product->get_attribute( 'your_attr' );

You will need to define $product if it's not on the page.

- (NSString *)removeWhitespaces {
  return [[self componentsSeparatedByCharactersInSet:
                    [NSCharacterSet whitespaceCharacterSet]]
      componentsJoinedByString:@""];
}

One more solution is to use contains which will return true or false

_.contains($(".right-tree").css("background-image"), "stage1")

Hope this helps

On server-side it will be not as accurate as with JavaScript. Meanwhile, sometimes it is required to solve such task. Just to share the possible solution in this case I write this answer.

If you need to determine user's time zone it could be done via Geo-IP services. Some of them providing timezone. For example, this one (http://smart-ip.net/geoip-api) could help:

<?php
$ip     = $_SERVER['REMOTE_ADDR']; // means we got user's IP address 
$json   = file_get_contents( 'http://smart-ip.net/geoip-json/' . $ip); // this one service we gonna use to obtain timezone by IP
// maybe it's good to add some checks (if/else you've got an answer and if json could be decoded, etc.)
$ipData = json_decode( $json, true);

if ($ipData['timezone']) {
    $tz = new DateTimeZone( $ipData['timezone']);
    $now = new DateTime( 'now', $tz); // DateTime object corellated to user's timezone
} else {
   // we can't determine a timezone - do something else...
}

Just made this piece of code, wich converts "this.altura" from negative to positive number. Hope this helps someone in need

       if(this.altura < 0){    

                        String aux = Integer.toString(this.altura);
                        char aux2[] = aux.toCharArray();
                        aux = "";
                        for(int con = 1; con < aux2.length; con++){
                            aux += aux2[con];
                        }
                        this.altura = Integer.parseInt(aux);
                        System.out.println("New Value: " + this.altura);
                    }

To get more information about tensorflow and its options you can use below command:

>> import tensorflow as tf
>> help(tf)

I used almost all of the answers posted here but not comfortable with that so i dig one step furter and found easy solution that fits my need and feel worth sharing with you guys.
Instead of iteration all over the options or using JQuery you can do using core JS in simple steps:

Example

<select id="org_list">
  <option value="23">IBM</option>
  <option value="33">DELL</option>
  <option value="25">SONY</option>
  <option value="29">HP</option>
</select>

So you must know the value of the option to select.

function selectOrganization(id){
    org_list=document.getElementById('org_list');
    org_list.selectedIndex=org_list.querySelector('option[value="'+id+'"]').index;
}

How to Use?

selectOrganization(25); //this will select SONY from option List

Your comments are welcome. :) AzmatHunzai.

hello i have had same problem an i did the steps with tommer and the problem solved thank you

note :

you don't have to go to that like just do this ;

1)-- Edit your “my.ini” file in c:\xampp\mysql\bin\ Change all default 3306 port entries to a new value 3308

2)--edit your “php.ini” in c:\xampp\php and replace 3306 by 3308

3)--Create the service entry - in Windows command line type

sc.exe create "mysqlweb" binPath= "C:\xampp\mysql\bin\mysqld.exe --defaults-file=c:\xampp\mysql\bin\my.ini mysqlweb"

4)--Open Windows Services and set Startup Type: Automatic, Start the service

You could use AJAX to call this controller action. For example if you are using jQuery you might use the $.ajax() method:

<script type="text/javascript">
    $.ajax({
        url: '@Url.Action("NameOfYourAction")',
        type: 'GET',
        cache: false,
        success: function(result) {
            // you could use the result.values dictionary here
        }
    });
</script>

On my machine mysqld service stopped that's why it was giving me the same problem.

1:- Go to terminal and type

sudo service mysqld restart

This will restart the mysqld service and create a new sock file on the required location.

If you want to select text between two matching parentheses, you are out of luck with regular expressions. This is impossible^(*).

This regex just returns the text between the first opening and the last closing parentheses in your string.

^(*) Unless your regex engine has features like balancing groups or recursion. The number of engines that support such features is slowly growing, but they are still not a commonly available.

If you will change the ID then Toggle will not working same problem was with me i just change

<div class="collapse navbar-collapse" id="defaultNavbar1">
    <ul class="nav navbar-nav">

id="defaultNavbar1" then toggle is working

Since these are member functions, call it as a member function on the instance, self.

def isNear(self, p):
    self.distToPoint(p)
    ...

I don't think you need complicated intermediate functions or eval or be dependent on global variables like window:

function fun1(arg) {
  console.log(arg);
}

function fun2(arg) {
  console.log(arg);
}

const operations = {
  fun1,
  fun2
};

operations["fun1"]("Hello World");
operations.fun2("Hello World");

// You can use intermediate variables, if you like
let temp = "fun1";
operations[temp]("Hello World");

It will also work with imported functions:

// mode.js
export function fun1(arg) {
  console.log(arg);
}

export function fun2(arg) {
  console.log(arg);
}

// index.js
import { fun1, fun2 } from "./mod";

const operations = {
  fun1,
  fun2
};

operations["fun1"]("Hello World");
operations["fun2"]("Hello World");

Since it is using property access, it will survive minimization or obfuscation, contrary to some answers you will find here.

Set equal name attributes to create a group;

<form>_x000D_
  <fieldset id="group1">_x000D_
    <input type="radio" value="value1" name="group1">_x000D_
    <input type="radio" value="value2" name="group1">_x000D_

    <input type="radio" value="value3" name="group2">_x000D_
  </fieldset>_x000D_
</form>

This is an old bug, but I encountered it today on a web service which had barely been altered since being created via "New \ Project.."

For me, this issue was caused by the "IService.cs" file containing the following:

<%@ ServiceHost Language="C#" Debug="true" Service="JSONWebService.Service1.svc" CodeBehind="Service1.svc.cs" %>

Notice the value in the Service attribute contains ".svc" at the end.

This shouldn't be there.

Removing those 4 characters resolved this issue.

<%@ ServiceHost Language="C#" Debug="true" Service="JSONWebService.Service1" CodeBehind="Service1.svc.cs" %>

Note that you need to open this file from outside of Visual Studio.

Visual Studio shows one file, Service1.cs in the Solution Explorer, but that only lets you alter Service1.svc.cs, not the Service1.svc file.

Use Google Sheets instead of Excel - this feature is built in, so you can use regex right from the find and replace dialog.

To answer your question:

1. Copy the data from Excel and paste into Google Sheets
2. Use the find and replace dialog with regex
3. Copy the data from Google Sheets and paste back into Excel

You also can lead your initial string, which you are going to check for pattern matching, to lower case. And using in your pattern lower case symbols respectively .

I may be way way too late but it could help someone in the future.
This answer is a modification to mangu23 answer
I only added a for loop to avoid repetition and to easily add more fragments without boilerplate code.

We first need a list of the fragments that should be displayed

public class MainActivity extends AppCompatActivity{
    //...
    List<Fragment> fragmentList = new ArrayList<>();
}

Then we need to fill it with our fragments

@Override
protected void onCreate(Bundle savedInstanceState) {
    //...
    HomeFragment homeFragment = new HomeFragment();
    MessagesFragment messagesFragment = new MessagesFragment();
    UserFragment userFragment = new UserFragment();
    FavoriteFragment favoriteFragment = new FavoriteFragment();
    MapFragment mapFragment = new MapFragment();

    fragmentList.add(homeFragment);
    fragmentList.add(messagesFragment);
    fragmentList.add(userFragment);
    fragmentList.add(favoriteFragment);
    fragmentList.add(mapFragment);
}

And we need a way to know which fragment were selected from the list, so we need getFragmentIndex function

private int getFragmentIndex(Fragment fragment) {
    int index = -1;
    for (int i = 0; i < fragmentList.size(); i++) {
        if (fragment.hashCode() == fragmentList.get(i).hashCode()){
            return i;
        }
    }
    return index;
}

And finally, the displayFragment method will like this:

private void displayFragment(Fragment fragment) {
        int index = getFragmentIndex(fragment);
        FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
        if (fragment.isAdded()) { // if the fragment is already in container
            transaction.show(fragment);
        } else { // fragment needs to be added to frame container
            transaction.add(R.id.placeholder, fragment);
        }
        // hiding the other fragments
        for (int i = 0; i < fragmentList.size(); i++) {
            if (fragmentList.get(i).isAdded() && i != index) {
                transaction.hide(fragmentList.get(i));
            }
        }
        transaction.commit();
    }

In this way, we can call displayFragment(homeFragment) for example.
This will automatically show the HomeFragment and hide any other fragment in the list.
This solution allows you to append more fragments to the fragmentList without having to repeat the if statements in the old displayFragment version.
I hope someone will find this useful.

I ran across a solution that doesn't use image maps at all but rather anchor tags that are absolutely positioned over the image. The only drawback would be that the hotspot would have to be rectangular, but the plus is that this solution doesn't rely on Javascript, just CSS. There is a website that you can use to generate the HTML code for the anchors: http://www.zaneray.com/responsive-image-map/

I put the image and the generated anchor tags in a relatively positioned div tag and everything worked perfectly on window resize and on my mobile phone.

If you want to log errors from web-page, you should use WebChromeClient and override its onConsoleMessage:

webView.settings.apply {
    javaScriptEnabled = true
    javaScriptCanOpenWindowsAutomatically = true
    domStorageEnabled = true
}
webView.webViewClient = WebViewClient()
webView.webChromeClient = MyWebChromeClient()

private class MyWebChromeClient : WebChromeClient() {
    override fun onConsoleMessage(consoleMessage: ConsoleMessage): Boolean {
        Timber.d("${consoleMessage.message()}")
        Timber.d("${consoleMessage.lineNumber()} ${consoleMessage.sourceId()}")
        return super.onConsoleMessage(consoleMessage)
    }
}

The C language definition specifies minimum ranges for various data types. For int, this minimum range is -32767 to 32767, meaning an int must be at least 16 bits wide. An implementation is free to provide a wider int type with a correspondingly wider range. For example, on the SLES 10 development server I work on, the range is -2147483647 to 2137483647.

There are still some systems out there that use 16-bit int types (All The World Is Not A VAX x86), but there are plenty that use 32-bit int types, and maybe a few that use 64-bit.

The C language was designed to run on different architectures. Java was designed to run in a virtual machine that hides those architectural differences.

In java and C# all the object references are pointers, the thing with c++ is that you have more control on where you pointer points. Remember With great power comes grand responsibility.

I honestly suggest that you use moment.js. Just download moment.min.js and then use this snippet to get your date in whatever format you want:

<script>
$(document).ready(function() {

     // set an element
     $("#date").val( moment().format('MMM D, YYYY') );

     // set a variable
     var today = moment().format('D MMM, YYYY');

});
</script>

Use following chart for date formats:

You can do it this way:

xml.Descendants().SingleOrDefault(p => p.Name.LocalName == "Name of the node to find")

where xml is a XDocument.

Be aware that the property Name returns an object that has a LocalName and a Namespace. That's why you have to use Name.LocalName if you want to compare by name.

Actually the list of parameters could be accessed with $1 $2 ... etc.
Which is exactly equivalent to:

${!i}

So, the list of parameters could be changed with set,
and ${!i} is the correct way to access them:

$ set -- aa bb cc dd 55 ff gg hh ii jjj kkk lll
$ for ((i=0;i<=$#;i++)); do echo "$#" "$i" "${!i}"; done

12 1 aa
12 2 bb
12 3 cc
12 4 dd
12 5 55
12 6 ff
12 7 gg
12 8 hh
12 9 ii
12 10 jjj
12 11 kkk
12 12 lll

For your specific case, this could be used (without the need for arrays), to set the list of arguments when none was given:

if [ "$#" -eq 0 ]; then
    set -- defaultarg1 defaultarg2
fi

which translates to this even simpler expression:

[ "$#" == "0" ] && set -- defaultarg1 defaultarg2

There are many way you can do this. Those are given bellow:

Suppose your original number is given bellow: double number = 2354548.235;

Using NumberFormat and Rounding mode

NumberFormat nf = DecimalFormat.getInstance(Locale.ENGLISH);
    DecimalFormat decimalFormatter = (DecimalFormat) nf;
    decimalFormatter.applyPattern("#,###,###.##");
    decimalFormatter.setRoundingMode(RoundingMode.CEILING);

    String fString = decimalFormatter.format(number);
    System.out.println(fString);

Using String formatter

System.out.println(String.format("%1$,.2f", number));

In all cases the output will be: 2354548.24

Note:

During rounding you can add RoundingMode in your formatter. Here are some Rounding mode given bellow:

    decimalFormat.setRoundingMode(RoundingMode.CEILING);
    decimalFormat.setRoundingMode(RoundingMode.FLOOR);
    decimalFormat.setRoundingMode(RoundingMode.HALF_DOWN);
    decimalFormat.setRoundingMode(RoundingMode.HALF_UP);
    decimalFormat.setRoundingMode(RoundingMode.UP);

Here are the imports:

import java.math.BigDecimal;
import java.math.RoundingMode;
import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.Locale;

Set a local value with the observer

...also, don't forget to initialize the value with dummy data to avoid uninitialized errors.

export class ModelService {
    constructor() {
      this.mode = new Model();

      this._http.get('/api/v1/cats')
      .map(res => res.json())
      .subscribe(
        json => {
          this.model = new Model(json);
        },
        error => console.log(error);
      );
    }
}

This assumes Model, is a data model representing the structure of your data.

Model with no parameters should create a new instance with all values initialized (but empty). That way, if the template renders before the data is received it won't throw an error.

Ideally, if you want to persist the data to avoid unnecessary http requests you should put this in an object that has its own observer that you can subscribe to.

? 1. Can I set state inside a useEffect hook?

In principle, you can set state freely where you need it - including inside useEffect and even during rendering. Just make sure to avoid infinite loops by settting Hook deps properly and/or state conditionally.

? 2. Lets say I have some state that is dependent on some other state. Is it appropriate to create a hook that observes A and sets B inside the useEffect hook?

You just described the classic use case for useReducer:

useReducer is usually preferable to useState when you have complex state logic that involves multiple sub-values or when the next state depends on the previous one. (React docs)

When setting a state variable depends on the current value of another state variable, you might want to try replacing them both with useReducer. [...] When you find yourself writing setSomething(something => ...), it’s a good time to consider using a reducer instead. (Dan Abramov, Overreacted blog)

? 3. Will the effects cascade such that, when I click the button, the first effect will fire, causing b to change, causing the second effect to fire, before the next render?

useEffect always runs after the render is committed and DOM changes are applied. The first effect fires, changes b and causes a re-render. After this render has completed, second effect will run due to b changes.

  console.log("render");_x000D_

? 4. Are there any performance downsides to structuring code like this?

Yes. By wrapping the state change of b in a separate useEffect for a, the browser has an additional layout/paint phase - these effects are potentially visible for the user. If there is no way you want give useReducer a try, you could change b state together with a directly:

let MyComponent = () => {_x000D_

  let [a, setA] = useState(1);_x000D_
  let [b, setB] = useState(2);_x000D_

I've just fixed such an issue on my laptop running windows 10. Suddenly wamp became super slow - a request to load a page was taking 2 minutes.

After trying numerous things, what it turned out to fix the problem was disabling windows defender. All worked like a charm after that.

p.s. I'd suggest you add your apache root dir to the exceptions list and not actually disable defender completely.

You must modify the query like this

CREATE TABLE #TMPGUARDIAN(
LAST_NAME NVARCHAR(30),
FRST_NAME NVARCHAR(30))  

INSERT INTO #TMPGUARDIAN(FRST_NAME,LAST_NAME)
SELECT LAST_NAME,FRST_NAME  FROM TBL_PEOPLE

-- Make a last session for clearing the all temporary tables. always drop at end. In your case, sometimes, there might be an error happen if the table is not exists, while you trying to delete.

DROP TABLE #TMPGUARDIAN

Avoid using insert into Because If you are using insert into then in future if you want to modify the temp table by adding a new column which can be filled after some process (not along with insert). At that time, you need to rework and design it in the same manner.

Use Table Variable http://odetocode.com/articles/365.aspx

declare @userData TABLE(
 LAST_NAME NVARCHAR(30),
    FRST_NAME NVARCHAR(30)
)

Advantages No need for Drop statements, since this will be similar to variables. Scope ends immediately after the execution.

Brief syntax lesson

Cells(Row, Column) identifies a cell. Row must be an integer between 1 and the maximum for version of Excel you are using. Column must be a identifier (for example: "A", "IV", "XFD") or a number (for example: 1, 256, 16384)

.Cells(Row, Column) identifies a cell within a sheet identified in a earlier With statement:

With ActiveSheet
  :
  .Cells(Row,Column)
  :
End With

If you omit the dot, Cells(Row,Column) is within the active worksheet. So wsh = ActiveWorkbook wsh.Range is not strictly necessary. However, I always use a With statement so I do not wonder which sheet I meant when I return to my code in six months time. So, I would write:

With ActiveSheet
  :
  .Range.  
  :
End With

Actually, I would not write the above unless I really did want the code to work on the active sheet. What if the user has the wrong sheet active when they started the macro. I would write:

With Sheets("xxxx")
  :
  .Range.  
  :
End With

because my code only works on sheet xxxx.

Cells(Row,Column) identifies a cell. Cells(Row,Column).xxxx identifies a property of the cell. Value is a property. Value is the default property so you can usually omit it and the compiler will know what you mean. But in certain situations the compiler can be confused so the advice to include the .Value is good.

Cells(Row,Column) like "*Miami*" will give True if the cell is "Miami", "South Miami", "Miami, North" or anything similar.

Cells(Row,Column).Value = "Miami" will give True if the cell is exactly equal to "Miami". "MIAMI" for example will give False. If you want to accept MIAMI, use the lower case function:

Lcase(Cells(Row,Column).Value) = "miami"  

My suggestions

Your sample code keeps changing as you try different suggestions which I find confusing. You were using Cells(Row,Column) <> "Miami" when I started typing this.

Use

If Cells(i, "A").Value like "*Miami*" And Cells(i, "D").Value like "*Florida*" Then
  Cells(i, "C").Value = "BA"

if you want to accept, for example, "South Miami" and "Miami, North".

Use

If Cells(i, "A").Value = "Miami" And Cells(i, "D").Value like "Florida" Then
  Cells(i, "C").Value = "BA"

if you want to accept, exactly, "Miami" and "Florida".

Use

If Lcase(Cells(i, "A").Value) = "miami" And _
   Lcase(Cells(i, "D").Value) = "florida" Then
  Cells(i, "C").Value = "BA"

if you don't care about case.

Taking up @ZF007's answer, this is not answering your question as a whole, but can be the solution for the same error. I post it here since I have not found a direct solution as an answer to this error message elsewhere on Stack Overflow.

The error appears when you check whether an array was empty or not.

• if np.array([1,2]): print(1) --> ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all().

• if np.array([1,2])[0]: print(1) --> no ValueError, but: if np.array([])[0]: print(1) --> IndexError: index 0 is out of bounds for axis 0 with size 0.

• if np.array([1]): print(1) --> no ValueError, but again will not help at an array with many elements.

• if np.array([]): print(1) --> DeprecationWarning: The truth value of an empty array is ambiguous. Returning False, but in future this will result in an error. Use 'array.size > 0' to check that an array is not empty.

Doing so:

• if np.array([]).size: print(1) solved the error.

Use

$(document).on("click", "#btn_a", function(){
  alert ('button clicked');
});

to add the listener for the dynamically created button.

alert($("#btn_a").val());

will give you the value of the button

You can also do

if ($ie) {
    # Do Something if $ie is not null
}

you could always do something like

myString = "false"
val = (myString == "true")

the bit in parens would evaluate to False. This is just another way to do it without having to do an actual function call.

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.

Reference: https://developer.mozilla.org/en-US/docs/Web/API/Window/location

Less obvious but more than 2 times faster :

// 10000000 runs

DateTime d = DateTime.Now;

// 484,375ms
d = new DateTime((d.Ticks / TimeSpan.TicksPerSecond) * TimeSpan.TicksPerSecond);

// 1296,875ms
d = d.AddMilliseconds(-d.Millisecond);

You need to use df.shift here.
df.shift(i) shifts the entire dataframe by i units down.

So, for i = 1:

Input:

    x1   x2  
0  206  214  
1  226  234  
2  245  253  
3  265  272    
4  283  291

Output:

    x1   x2
0  Nan  Nan   
1  206  214  
2  226  234  
3  245  253  
4  265  272 

So, run this script to get the expected output:

import pandas as pd

df = pd.DataFrame({'x1': ['206', '226', '245',' 265', '283'],
                   'x2': ['214', '234', '253', '272', '291']})

print(df)
df['x2'] = df['x2'].shift(1)
print(df)

Instead of using a margin, could you use a border? You should do this with <div>, anyway.

Something like this?

In my case, is a permission problem.

I changed the log level to DEBUG3, and in /var/log/secure I see this line:

Authentication refused: bad ownership or modes for directory

Googled and I found this post:

https://www.daveperrett.com/articles/2010/09/14/ssh-authentication-refused/

chmod g-w /home/your_user
chmod 700 /home/your_user/.ssh
chmod 600 /home/your_user/.ssh/authorized_keys

Basically, it tells me to:

• get rid of group w permission of your user home dir
• change permission to 700 of the .ssh dir
• change permission to 600 of the authorized_keys file.

And that works.

Another thing is that even I enabled root login, I cannot get root to work. Better use another user.

For the toast message in flutter use bot_toast library. This library provides Feature-rich, support for displaying notifications, text, loading, attachments, etc. Toast

Ok here is my version of doing this. I noticed that you want your output to be 7, which means you dont want to count special characters and numbers. So here is regex pattern:

re.findall("[a-zA-Z_]+", string)

Where [a-zA-Z_] means it will match any character beetwen a-z (lowercase) and A-Z (upper case).

About spaces. If you want to remove all extra spaces, just do:

string = string.rstrip().lstrip() # Remove all extra spaces at the start and at the end of the string
while "  " in string: # While  there are 2 spaces beetwen words in our string...
    string = string.replace("  ", " ") # ... replace them by one space!

I figured it out. I was referencing JavaSE-1.5 and using JDK 1.6. I changed it to use 1.6 and that appears to fix it.

Seems like through my research that is an overloaded error message that covers a lot of error cases.

Here are more approaches for doing this by using numpy.ravel(), numpy.array(), utilizing the fact that 1D arrays can be unpacked into plain elements:

# we'll utilize the concept of unpacking
In [15]: (*a, *b)
Out[15]: (1, 2, 3, 5, 6)

# using `numpy.ravel()`
In [14]: np.ravel((*a, *b))
Out[14]: array([1, 2, 3, 5, 6])

# wrap the unpacked elements in `numpy.array()`
In [16]: np.array((*a, *b))
Out[16]: array([1, 2, 3, 5, 6])

I got the same problem in here, and guess what.... looking at the csproj's xml' structure, I noticed the Content node (inside ItemGroup node) was as "none"... not sure why but that was the reason I was getting the same error, just edited that to "Content" as the others, and it's working.

Hope that helps

Make sure:

<meta http-equiv="X-UA-Compatible" content="IE=edge">

is the first <meta> tag on your page, otherwise IE may not respect it.

Alternatively, the problem may be that IE is using Enterprise Mode for this website:

• Your question mentioned that the console shows: HTML1122: Internet Explorer is running in Enterprise Mode emulating IE8.
• If so you may need to disable enterprise mode (or like this) or turn it off for that website from the Tools menu in IE.
• However Enterprise Mode should in theory be overridden by the X-UA-Compatible tag, but IE might have a bug...

Useful Utils methods as below for manage Time in GMT with DST Savings:

public static Date convertToGmt(Date date) {
    TimeZone tz = TimeZone.getDefault();
    Date ret = new Date(date.getTime() - tz.getRawOffset());

    // if we are now in DST, back off by the delta.  Note that we are checking the GMT date, this is the KEY.
    if (tz.inDaylightTime(ret)) {
        Date dstDate = new Date(ret.getTime() - tz.getDSTSavings());

        // check to make sure we have not crossed back into standard time
        // this happens when we are on the cusp of DST (7pm the day before the change for PDT)
        if (tz.inDaylightTime(dstDate)) {
            ret = dstDate;
        }
    }
    return ret;
}

public static Date convertFromGmt(Date date) {
    TimeZone tz = TimeZone.getDefault();
    Date ret = new Date(date.getTime() + tz.getRawOffset());

    // if we are now in DST, back off by the delta.  Note that we are checking the GMT date, this is the KEY.
    if (tz.inDaylightTime(ret)) {
        Date dstDate = new Date(ret.getTime() + tz.getDSTSavings());

        // check to make sure we have not crossed back into standard time
        // this happens when we are on the cusp of DST (7pm the day before the change for PDT)
        if (tz.inDaylightTime(dstDate)) {
            ret = dstDate;
        }
    }
    return ret;
}

Here are two ways you could do this, if you are scheduling the reboot.

First you could create a task on one machine using credentials that have rights needed to connect and reboot another machine. This makes the scheduler responsible for securely storing the credentials. The reboot command (I'm a Powershell guy, but this is cleaner.) is:

SHUTDOWN /r /f /m \\ComputerName

The command line to create a scheduled task on the local machine, to remotely reboot another, would be:

SCHTASKS /Create /TN "Reboot Server" /TR "shutdown.exe /r /f /m \\ComputerName" /SC ONCE /ST 00:00 /SD "12/24/2012" /RU "domain\username" /RP "password"

I prefer the second way, where you use your current credentials to create a scheduled task that runs with the system account on a remote machine.

SCHTASKS /Create /TN "Reboot Server" /TR "shutdown.exe /r /f" /SC ONCE /ST 00:00 /SD "12/24/2012" /RU SYSTEM /S ComputerName

This also works through the GUI, just enter SYSTEM as the user name, leaving the password fields blank.

In your batch file do this

set source=C:\Users\Habib\test
set destination=C:\Users\Habib\testdest\
xcopy %source% %destination% /y

If you want to copy the sub directories including empty directories then do:

xcopy %source% %destination% /E /y

If you only want to copy sub directories and not empty directories then use /s like:

xcopy %source% %destination% /s /y

Though Dan Lowe's excellent answer very thoroughly answered the OP's question about the difference between PUT and PATCH, its answer to the question of why PATCH is not idempotent is not quite correct.

To show why PATCH isn't idempotent, it helps to start with the definition of idempotence (from Wikipedia):

The term idempotent is used more comprehensively to describe an operation that will produce the same results if executed once or multiple times [...] An idempotent function is one that has the property f(f(x)) = f(x) for any value x.

In more accessible language, an idempotent PATCH could be defined as: After PATCHing a resource with a patch document, all subsequent PATCH calls to the same resource with the same patch document will not change the resource.

Conversely, a non-idempotent operation is one where f(f(x)) != f(x), which for PATCH could be stated as: After PATCHing a resource with a patch document, subsequent PATCH calls to the same resource with the same patch document do change the resource.

To illustrate a non-idempotent PATCH, suppose there is a /users resource, and suppose that calling GET /users returns a list of users, currently:

[{ "id": 1, "username": "firstuser", "email": "[email protected]" }]

Rather than PATCHing /users/{id}, as in the OP's example, suppose the server allows PATCHing /users. Let's issue this PATCH request:

PATCH /users
[{ "op": "add", "username": "newuser", "email": "[email protected]" }]

Our patch document instructs the server to add a new user called newuser to the list of users. After calling this the first time, GET /users would return:

[{ "id": 1, "username": "firstuser", "email": "[email protected]" },
 { "id": 2, "username": "newuser", "email": "[email protected]" }]

Now, if we issue the exact same PATCH request as above, what happens? (For the sake of this example, let's assume that the /users resource allows duplicate usernames.) The "op" is "add", so a new user is added to the list, and a subsequent GET /users returns:

[{ "id": 1, "username": "firstuser", "email": "[email protected]" },
 { "id": 2, "username": "newuser", "email": "[email protected]" },
 { "id": 3, "username": "newuser", "email": "[email protected]" }]

The /users resource has changed again, even though we issued the exact same PATCH against the exact same endpoint. If our PATCH is f(x), f(f(x)) is not the same as f(x), and therefore, this particular PATCH is not idempotent.

Although PATCH isn't guaranteed to be idempotent, there's nothing in the PATCH specification to prevent you from making all PATCH operations on your particular server idempotent. RFC 5789 even anticipates advantages from idempotent PATCH requests:

A PATCH request can be issued in such a way as to be idempotent, which also helps prevent bad outcomes from collisions between two PATCH requests on the same resource in a similar time frame.

In Dan's example, his PATCH operation is, in fact, idempotent. In that example, the /users/1 entity changed between our PATCH requests, but not because of our PATCH requests; it was actually the Post Office's different patch document that caused the zip code to change. The Post Office's different PATCH is a different operation; if our PATCH is f(x), the Post Office's PATCH is g(x). Idempotence states that f(f(f(x))) = f(x), but makes no guarantes about f(g(f(x))).

To compare entire revisions, it's simply:

svn diff -r 8979:11390

If you want to compare the last committed state against your currently saved working files, you can use convenience keywords:

svn diff -r PREV:HEAD

(Note, without anything specified afterwards, all files in the specified revisions are compared.)

You can compare a specific file if you add the file path afterwards:

svn diff -r 8979:HEAD /path/to/my/file.php

I would do something like the following:

INSERT INTO cache VALUES (key, generation)
ON DUPLICATE KEY UPDATE (key = key, generation = generation + 1);

Setting the generation value to 0 in code or in the sql but the using the ON DUP... to increment the value. I think that's the syntax anyway.

Well, if only for research purposes, then your best bet is to look at this Wikipedia entry on Filenames.

If you want to write a portable function to validate user input and create filenames based on that, the short answer is don't. Take a look at a portable module like Perl's File::Spec to have a glimpse to all the hops needed to accomplish such a "simple" task.

If you want to rule out any problems with the else part, try removing the else and place the command on a new line. Like this:

IF EXIST D:\RPS_BACKUP\backups_temp\ goto tempexists
goto tempexistscontinue  

One of the nice things about IntelliJ is that you don't need to use their annotations. You can write your own, or you can use those of whatever other tool you like. You're not even limited to a single type. If you're using two libraries that use different @NotNull annotations, you can tell IntelliJ to use both of them. To do this, go to "Configure Inspections", click on the "Constant Conditions & Exceptions" inspection, and hit the "Configure inspections" button. I use the Nullness Checker wherever I can, so I set up IntelliJ to use those annotations, but you can make it work with whatever other tool you want. (I have no opinion on the other tools because I've been using IntelliJ's inspections for years, and I love them.)

In your ajax success callback do this:

success: function(data){
   if(data.success == true){ // if true (1)
      setTimeout(function(){// wait for 5 secs(2)
           location.reload(); // then reload the page.(3)
      }, 5000); 
   }
}

As you want to reload the page after 5 seconds, then you need to have a timeout as suggested in the answer.

You could possibly make your own Map.of (which is only available in Java 9 and higher) method easily in 2 easy ways

Make it with a set amount of parameters

Example

public <K,V> Map<K,V> mapOf(K k1, V v1, K k2, V v2 /* perhaps more parameters */) {
    return new HashMap<K, V>() {{
      put(k1, v1);
      put(k2,  v2);
      // etc...
    }};
}

Make it using a List

You can also make this using a list, instead of making a lot of methods for a certain set of parameters.

Example

public <K, V> Map<K, V> mapOf(List<K> keys, List<V> values) {
   if(keys.size() != values.size()) {
        throw new IndexOutOfBoundsException("amount of keys and values is not equal");
    }

    return new HashMap<K, V>() {{
        IntStream.range(0, keys.size()).forEach(index -> put(keys.get(index), values.get(index)));
    }};
}

Note It is not recommended to use this for everything as this makes an anonymous class every time you use this.

The solution for me was to install the oracle unlimited JCE and install in JRE_HOME/lib/security. Then restarted glassfish and I was able to connect to my sftp server using jsch.

you can use preload="none" in the attribute of video tag so the video will be displayed only when user clicks on play button.

<video preload="none">

You can do this from ECMAScript 6 onwards using arrays and "destructuring assignments". Note that these are not available in older Javascript versions (meaning — neither with ECMAScript 3rd nor 5th editions).

It allows you to assign to 1+ variables simultaneously:

var [x, y] = [1, 2];
x; // 1
y; // 2

// or

[x, y] = (function(){ return [3, 4]; })();
x; // 3
y; // 4

You can also use object destructuring combined with property value shorthand to name the return values in an object and pick out the ones you want:

let {baz, foo} = (function(){ return {foo: 3, bar: 500, baz: 40} })();
baz; // 40
foo; // 3

And by the way, don't be fooled by the fact that ECMAScript allows you to return 1, 2, .... What really happens there is not what might seem. An expression in return statement — 1, 2, 3 — is nothing but a comma operator applied to numeric literals (1 , 2, and 3) sequentially, which eventually evaluates to the value of its last expression — 3. That's why return 1, 2, 3 is functionally identical to nothing more but return 3.

return 1, 2, 3;
// becomes
return 2, 3;
// becomes
return 3;

I have the same problem and i think the firewall is blocking the git protocol. So in the end I have to resort to using https:// to fetch and push. However this will always prompt the user to enter the password...

here is the example what working for me (just to share with those cant use git:// protocol :)

git fetch https://[user-name]@github.com/[user-name]/[project].git

if the above works, you can remove the origin and replace with

git remote rm origin  
git remote add origin https://[user-name]@github.com/[user-name]/[project].git

$(function() {
  $(":text").keypress(check_submit).each(function() {
    check_submit();
  });
});

function check_submit() {
  if ($(this).val().length == 0) {
    $(":submit").attr("disabled", true);
  } else {
    $(":submit").removeAttr("disabled");
  }
}

The below code works for me, for both accessing and changing a pixel value.

For accessing pixel's channel value :

for (int i = 0; i < image.cols; i++) {
    for (int j = 0; j < image.rows; j++) {
        Vec3b intensity = image.at<Vec3b>(j, i);
        for(int k = 0; k < image.channels(); k++) {
            uchar col = intensity.val[k]; 
        }   
    }
}

For changing a pixel value of a channel :

uchar pixValue;
for (int i = 0; i < image.cols; i++) {
    for (int j = 0; j < image.rows; j++) {
        Vec3b &intensity = image.at<Vec3b>(j, i);
        for(int k = 0; k < image.channels(); k++) {
            // calculate pixValue
            intensity.val[k] = pixValue;
        }
     }
}

Just use Date constructor to compare with string input:

function isDate(str) {_x000D_
  return 'string' === typeof str && (dt = new Date(str)) && !isNaN(dt) && str === dt.toISOString().substr(0, 10);_x000D_
}_x000D_
_x000D_
console.log(isDate("2018-08-09"));_x000D_
console.log(isDate("2008-23-03"));_x000D_
console.log(isDate("0000-00-00"));_x000D_
console.log(isDate("2002-02-29"));_x000D_
console.log(isDate("2004-02-29"));

Firefox Screenshots is a new tool that ships with Firefox. It is not a developer tool, it is aimed at end-users of the browser.

To take a screenshot, click on the page actions menu in the address bar, and click "take a screenshot". If you then click "Save full page", it will save the full page, scrolling for you.

From The Zen of Python:

There should be one-- and preferably only one --obvious way to do it.

You can also use a regular expression as a field separator. The following will print "bar" by using a regular expression to set the number "10" as a separator.

echo "foo 10 bar" | awk -F'[0-9][0-9]' '{print $2}'

As far as I know the for loop uses the iter function and you should not mess with a structure while iterating over it.

Does it have to be a dictionary? If you use a list something like this might work:

while len(my_list) > 0:
    #get last item from list
    key, value = my_list.pop()
    #do something with key and value
    #maybe
    my_list.append((key, value))

Note that my_list is a list of the tuple (key, value). The only disadvantage is that you cannot access by key.

EDIT: Nevermind, the answer above is mostly the same.

You could always add it to your Connection String:

connect timeout=180;

I have 2 targets in my project, Free and Paid. My mistake was i was looking at my free target while trying to build the paid target, a stupid mistake but possible someone out there might learn from this as well.

Since I only use admin interface in my app, I put this in the admin.py :

admin.site.site_header = 'My administration'

This is an old post and the links are no longer valid but because it came up early in a search I was doing I thought I should comment to help others understand the problem better.

By using float you are asking the browser to arrange your controls automatically. It responds by wrapping when the controls don't fit the width for their specified float arrangement. float:left, float:right or clear:left,clear:right,clear:both.

So if you want to force a bunch of float:left items to float uniformly into one left column then you need to make the browser decide to wrap/unwrap them at the same width. Because you don't want to do any scripting you can wrap all of the controls you want to float together in a single div. You would want to add a new wrapping div with a class like:

.LeftImages{
    float:left;
}

html

<div class="LeftImages">   
  <img...>   
  <img...> 
</div>

This div will automatically adjust to the width of the largest image and all the images will be floated left with the div all the time (no wrapping).

If you still want them to wrap you can give the div a width like width:30% and each of the images the float:left; style. Rather than adjust to the largest image it will vary in size and allow the contained images to wrap.

Here is a solution found at http://www.mrexcel.com/forum/excel-questions/510011-fails-activeworkbook-refreshall-backgroundquery-%3Dfalse.html:

Either have all the pivotcaches' backgroundquery properties set to False, or loop through all the workbook's pivotcaches:

Code:
    For Each pc In ActiveWorkbook.PivotCaches
       pc.BackgroundQuery = False
       pc.Refresh
    Next 

this will leave all pivotcaches backgroundquery properties as false. You could retain each one's settings with:

Code:

For Each pc In ActiveWorkbook.PivotCaches
  originalBGStatus = pc.BackgroundQuery
  pc.BackgroundQuery = False
  pc.Refresh
  pc.BackgroundQuery = originalBGStatus
Next

Correct, use --httpPort parameter. If you also want to specify the $JENKINS_HOME, you can do like this:

java -DJENKINS_HOME=/Users/Heros/jenkins -jar jenkins.war  --httpPort=8484

Actually you can only style few CSS properties on :modified option elements. color does not work, background-color either, but you can set a background-image.

You can couple this with gradients to do the trick.

option:hover,_x000D_
option:focus,_x000D_
option:active,_x000D_
option:checked {_x000D_
  background: linear-gradient(#5A2569, #5A2569);_x000D_
}

<select>_x000D_
  <option>A</option>_x000D_
  <option>B</option>_x000D_
  <option>C</option>_x000D_
</select>

Works on gecko/webkit.

If you are using Angular 7 or a previous version and you dont' have access to the clear() method, there is a way to achieve that without doing any loop:

yourFormGroup.controls.youFormArrayName = new FormArray([]);

You can't use float inside flex container and the reason is that float property does not apply to flex-level boxes as you can see here Fiddle.

So if you want to position child element to right of parent element you can use margin-left: auto but now child element will also push other div to the right as you can see here Fiddle.

What you can do now is change order of elements and set order: 2 on child element so it doesn't affect second div

.parent {_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  margin-left: auto;_x000D_
  order: 2;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Ignore parent?</div>_x000D_
  <div>another child</div>_x000D_
</div>

In my case I showed DialogFragment in Activity. In this dialog fragment I wrote as in DialogFragment remove black border:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setStyle(STYLE_NO_FRAME, 0)
}

override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
    super.onCreateDialog(savedInstanceState)

    val dialog = Dialog(context!!, R.style.ErrorDialogTheme)
    val inflater = LayoutInflater.from(context)
    val view = inflater.inflate(R.layout.fragment_error_dialog, null, false)
    dialog.setTitle(null)
    dialog.setCancelable(true)
    dialog.setContentView(view)
    return dialog
}

Either remove setStyle(STYLE_NO_FRAME, 0) in onCreate() or chande/remove onCreateDialog. Because dialog settings have changed after the dialog has been created.

You need to find what your local network's IP of that computer is. Then other people can access to your site by that IP.

You can find your local network's IP by go to Command Prompt or press Windows + R then type in ipconfig. It will give out some information and your local IP should look like 192.168.1.x.

Your function will return the size of a ResultSet, but its cursor will be set after last record, so without rewinding it by calling beforeFirst(), first() or previous() you won't be able to read its rows, and rewinding methods won't work with forward only ResultSet (you'll get the same exception you're getting in your second code fragment).

next - it's like return, but for blocks! (So you can use this in any proc/lambda too.)

That means you can also say next n to "return" n from the block. For instance:

puts [1, 2, 3].map do |e|
  next 42 if e == 2
  e
end.inject(&:+)

This will yield 46.

Note that return always returns from the closest def, and never a block; if there's no surrounding def, returning is an error.

Using return from within a block intentionally can be confusing. For instance:

def my_fun
  [1, 2, 3].map do |e|
    return "Hello." if e == 2
    e
  end
end

my_fun will result in "Hello.", not [1, "Hello.", 2], because the return keyword pertains to the outer def, not the inner block.

if you don't export default in A, B, C but just export {} then it's possible to do so

// things/A.js
export function A() {}

// things/B.js
export function B() {}

// things/C.js
export function C() {}

// foo.js
import * as Foo from ./thing
Foo.A()
Foo.B()
Foo.C()

Think of ob_start() as saying "Start remembering everything that would normally be outputted, but don't quite do anything with it yet."

For example:

ob_start();
echo("Hello there!"); //would normally get printed to the screen/output to browser
$output = ob_get_contents();
ob_end_clean();

There are two other functions you typically pair it with: ob_get_contents(), which basically gives you whatever has been "saved" to the buffer since it was turned on with ob_start(), and then ob_end_clean() or ob_flush(), which either stops saving things and discards whatever was saved, or stops saving and outputs it all at once, respectively.

Since Snow Leopard, up to Catalina and Big Sur, every version of macOS supports this:

sudo lsof -iTCP -sTCP:LISTEN -n -P

Personally I've end up with this simple function in my ~/.bash_profile:

listening() {
    if [ $# -eq 0 ]; then
        sudo lsof -iTCP -sTCP:LISTEN -n -P
    elif [ $# -eq 1 ]; then
        sudo lsof -iTCP -sTCP:LISTEN -n -P | grep -i --color $1
    else
        echo "Usage: listening [pattern]"
    fi
}

Then listening command gives you a listing of processes listening on some port and listening smth greps this for some pattern.

Having this, it's quite easy to ask about particular process, e.g. listening dropbox, or port, e.g. listening 22.

lsof command has some specialized options for asking about port, protocol, process etc. but personally I've found above function much more handy, since I don't need to remember all these low-level options. lsof is quite powerful tool, but unfortunately not so comfy to use.

Here is a script i wrote a while back (it is written using the jQuery library):

        return;
    }
    var moveIt = function () {
        var winWidth = $(window).width();
        var winHeight = $(window).height();
        el.css("position","absolute").css("left", ((winWidth / 2) - (el.width() / 2)) + "px").css("top", ((winHeight / 2) - (el.height() / 2)) + "px");
    }; 
    $(window).resize(moveIt);
    moveIt();
};

Bootstrap.yml is used to fetch config from the server. It can be for a Spring cloud application or for others. Typically it looks like:

spring:
  application:
    name: "app-name"
  cloud:
    config:
      uri: ${config.server:http://some-server-where-config-resides}

When we start the application it tries to connect to the given server and read the configuration based on spring profile mentioned in run/debug configuration.

If the server is unreachable application might even be unable to proceed further. However, if configurations matching the profile are present locally the server configs get overridden.

Good approach:

Maintain a separate profile for local and run the app using different profiles.

The other way to see it in windows command line :

tasklist /fi "imagename eq nginx.exe"

INFO: No tasks are running which match the specified criteria.

if there is a running nginx you will see them

Firstly a warning: you should never tinker with DOM that is managed by React, which you are doing by calling ReactDOM.render(<SampleComponent ... />);

With React, you should use SampleComponent directly in the main App.

var App = require('./App.js');
var SampleComponent = require('./SampleComponent.js');
ReactDOM.render(<App/>, document.body);

The content of your Component is irrelevant, but it should be used like this:

var App = React.createClass({
    render: function() {
        return (
            <div>
                <h1>App main component! </h1>
                <SampleComponent name="SomeName"/>
            </div>
        );
    }
});

You can then extend your app component to use a list.

var App = React.createClass({
    render: function() {
        var componentList = [
            <SampleComponent name="SomeName1"/>,
            <SampleComponent name="SomeName2"/>
        ]; // Change this to get the list from props or state
        return (
            <div>
                <h1>App main component! </h1>
                {componentList}
            </div>
        );
    }
});

I would really recommend that you look at the React documentation then follow the "Get Started" instructions. The time you spend on that will pay off later.

If you can catch this in time and you don't have the ability to ROLLBACK or use the transaction log, you can take a backup immediately and use a tool like Redgate's SQL Data Compare to generate a script to "restore" the affected data. This worked like a charm for me. :)

Best and Simple solution to follow:

Select the range of the columns you want to be copied to single column

Copy the range of cells (multiple columns)

Open Notepad++

Paste the selected range of cells

Press Ctrl+H, replace \t by \n and click on replace all

all the multiple columns fall under one single column

now copy the same and paste in excel

Simple and effective solution for those who dont want to waste time coding in VBA

If you need to reference a dynamically generated value you can also append query string paramters after the @URL.Action like so:

    var id = $(this).attr('id');
    var value = $(this).attr('value');
    $('#user_content').load('@Url.Action("UserDetails","User")?Param1=' + id + "&Param2=" + value);


    public ActionResult Details( int id, string value )
    {
        var model = GetFooModel();
        if (Request.IsAjaxRequest())
        {
            return PartialView( "UserDetails", model );
        }
        return View(model);
    }

You will have to create an auto-increment field with the sequence object (this object generates a number sequence).

Use the following CREATE SEQUENCE syntax:

  CREATE SEQUENCE seq_person
  MINVALUE 1
  START WITH 1
  INCREMENT BY 1
  CACHE 10

The code above creates a sequence object called seq_person, that starts with 1 and will increment by 1. It will also cache up to 10 values for performance. The cache option specifies how many sequence values will be stored in memory for faster access.

To insert a new record into the "Persons" table, we will have to use the nextval function (this function retrieves the next value from seq_person sequence):

  INSERT INTO Persons (P_Id,FirstName,LastName)
  VALUES (seq_person.nextval,'Lars','Monsen')

The SQL statement above would insert a new record into the "Persons" table. The "P_Id" column would be assigned the next number from the seq_person sequence. The "FirstName" column would be set to "Lars" and the "LastName" column would be set to "Monsen".

For Each row As DataRow In dtDataTable.Rows
    strDetail = row.Item("Detail")
Next row

There's also a shorthand:

For Each row As DataRow In dtDataTable.Rows
    strDetail = row("Detail")
Next row

Note that Microsoft's style guidelines for .Net now specifically recommend against using hungarian type prefixes for variables. Instead of "strDetail", for example, you should just use "Detail".

I found this version most suitable for all cases. It doesn't remove all whitespaces.

For example "a (test) b" -> "a b"

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim(); "Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();

try to compile

 compile 'com.android.support:cardview-v7:25.3.1'

The default value can be followed with a : after the property key, e.g.

<property name="port" value="${my.server.port:8080}" />

Or in java code:

@Value("${my.server.port:8080}")
private String myServerPort;

See:

• valueSeparator (from AbstractPropertyResolver)

• and VALUE_SEPARATOR (from SystemPropertyUtils)

BTW, the Elvis Operator is only available within Spring Expression Language (SpEL),
e.g.: https://stackoverflow.com/a/37706167/537554

Firstly, as Etienne says, float in C# is Single. It is just the C# keyword for that data type.

So you can definitely do this:

float f = 13.5f;
string s = f.ToString("R");

Secondly, you have referred a couple of times to the number's "format"; numbers don't have formats, they only have values. Strings have formats. Which makes me wonder: what is this thing you have that has a format but is not a string? The closest thing I can think of would be decimal, which does maintain its own precision; however, calling simply decimal.ToString should have the effect you want in that case.

How about including some example code so we can see exactly what you're doing, and why it isn't achieving what you want?

I tried to update a field with

$table->update(['field' => 'val']);

But it wasn't working, i had to modify my table Model to authorize this field to be edited : add 'field' in the array "protected $fillable"

Hope it will help someone :)

As several answer explained the you should run:

npm i

BUT if it does not solve...

Check the version of your npm executable. (For me it was 3.x.x which doesn't uses the package-lock.json (at all))

npm -v

It should be at least 5.x.x (which introduced the package-lock.json file.)

To update npm on Linux, follow these instructions.

For more details about package files, please read this medium story.

you just use variable type any and remove these types of problem.

error code :

  let accessToken = res;
  localStorage.setItem(LocalStorageConstants.TOKEN_KEY, accessToken);

given error Argument of type '{}' is not assignable to parameter of type 'string'.

success Code :

  var accessToken:any = res;
  localStorage.setItem(LocalStorageConstants.TOKEN_KEY, accessToken);

we create var type variable then use variable type any and resolve this issue.

any = handle any type of value so that remove error.

In general, methods that end in ! indicate that the method will modify the object it's called on. Ruby calls these as "dangerous methods" because they change state that someone else might have a reference to. Here's a simple example for strings:

foo = "A STRING"  # a string called foo
foo.downcase!     # modifies foo itself
puts foo          # prints modified foo

This will output:

a string

In the standard libraries, there are a lot of places you'll see pairs of similarly named methods, one with the ! and one without. The ones without are called "safe methods", and they return a copy of the original with changes applied to the copy, with the callee unchanged. Here's the same example without the !:

foo = "A STRING"    # a string called foo
bar = foo.downcase  # doesn't modify foo; returns a modified string
puts foo            # prints unchanged foo
puts bar            # prints newly created bar

This outputs:

A STRING
a string

Keep in mind this is just a convention, but a lot of Ruby classes follow it. It also helps you keep track of what's getting modified in your code.

For those who code-golf, an unreliable test with fewest characters:

function isArray(a) {
  return a.map;
}

This is commonly used when traversing/flattening a hierarchy:

function golf(a) {
  return a.map?[].concat.apply([],a.map(golf)):a;
}

input: [1,2,[3,4,[5],6],[7,[8,[9]]]]
output: [1, 2, 3, 4, 5, 6, 7, 8, 9]

When you run the Windows Command Prompt, and type in python, it starts the Python interpreter.

Typing it again tries to interpret python as a variable, which doesn't exist and thus won't work:

Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation.  All rights reserved.

C:\Users\USER>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> python
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'python' is not defined
>>> print("interpreter has started")
interpreter has started
>>> quit() # leave the interpreter, and go back to the command line

C:\Users\USER>

If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python is interpreted as a variable, which you have not defined.

Using explicit types in scan filters is ugly for me. I believe more elegant approach is to create own marker annotation:

@Retention(RetentionPolicy.RUNTIME)
public @interface IgnoreDuringScan {
}

Mark component that should be excluded with it:

@Component("foo") 
@IgnoreDuringScan
class Foo {
    ...
}

And exclude this annotation from your component scan:

@ComponentScan(excludeFilters = @Filter(IgnoreDuringScan.class))
public class MySpringConfiguration {}

$('#DateDepenseInput').val("2020-12-28")
the Format should be like Year-Month-Day
It worked well for me ...

@RobW's answer is correct, but this is more performant ! Because it uses a hashmap/set:

const customStringify = function (v) {
  const cache = new Set();
  return JSON.stringify(v, function (key, value) {
    if (typeof value === 'object' && value !== null) {
      if (cache.has(value)) {
        // Circular reference found
        try {
          // If this value does not reference a parent it can be deduped
         return JSON.parse(JSON.stringify(value));
        }
        catch (err) {
          // discard key if value cannot be deduped
         return;
        }
      }
      // Store value in our set
      cache.add(value);
    }
    return value;
  });
};

Added webkit specific values missing from above

I am assuming that we are dealing with a JFrame? The visible portion in the content pane - you have to use jframe.getContentPane().setBackground(...);

I have tried methods mentioned above, restarting the AS didn't work for me, and rebuilding didn't work either. Finally I found the problem was with the .9.png files, I deleted them and rebuilt the project, and it worked fine! Try it.

Try declaring the unit of width:

e1.style.width = "400px"; // width in PIXELS

Nope. The reason ActiveX can do it is because ActiveX is a little application that runs on the client's machine.

I would imagine access to such information via JavaScript would be a security vulnerability.

You can use curl this way:

curl -OL https://raw.githubusercontent.com/<username>/<repo-name>/<branch-name>/path/to/file

O means that curl downloads the content
L means that curl follows the redirection

Do you create the DataTables yourself? Because iterating through the children of any Object (as in DataSet.Tables) is usually not needed, as it's the job of the Parent to dispose all its child members.

Generally, the rule is: If you created it and it implements IDisposable, Dispose it. If you did NOT create it, then do NOT dispose it, that's the job of the parent object. But each object may have special rules, check the Documentation.

For .NET 3.5, it explicitly says "Dispose it when not using anymore", so that's what I would do.

The java documentation states:

The compiler does not consider return type when differentiating methods, so you cannot declare two methods with the same signature even if they have a different return type.

See: http://docs.oracle.com/javase/tutorial/java/javaOO/methods.html

As Jarret Hardie answered, hasattr will do the trick. I would like to add, though, that many in the Python community recommend a strategy of "easier to ask for forgiveness than permission" (EAFP) rather than "look before you leap" (LBYL). See these references:

EAFP vs LBYL (was Re: A little disappointed so far)
EAFP vs. LBYL @Code Like a Pythonista: Idiomatic Python

ie:

try:
    doStuff(a.property)
except AttributeError:
    otherStuff()

... is preferred to:

if hasattr(a, 'property'):
    doStuff(a.property)
else:
    otherStuff()

My issue was calling my program with the same name as one of its cocoapods. It caused a conflict. Solution: Create a program different name.

Thew problem is because of spaces in the titles(Headers). Remove spaces in all headers and it works fine.

Error 403.14 is the HTTP error code for not being allowed to list the contents of a directory. Please be sure that

Since I just lost two days of my life trying to solve for tryCatch for an irr function, I thought I should share my wisdom (and what is missing). FYI - irr is an actual function from FinCal in this case where got errors in a few cases on a large data set.

1. Set up tryCatch as part of a function. For example:

   irr2 <- function (x) {
     out <- tryCatch(irr(x), error = function(e) NULL)
     return(out)
   }
   

2. For the error (or warning) to work, you actually need to create a function. I originally for error part just wrote error = return(NULL) and ALL values came back null.

3. Remember to create a sub-output (like my "out") and to return(out).

You can handle the Firefox driver automatically using WebDriverManager.

This library downloads the proper binary (geckodriver) for your platform (Mac, Windows, Linux) and then exports the proper value of the required Java environment variable (webdriver.gecko.driver).

Take a look at a complete example as a JUnit test case:

public class FirefoxTest {

  private WebDriver driver;

  @BeforeClass
  public static void setupClass() {
    WebDriverManager.firefoxdriver().setup();
  }

  @Before
  public void setupTest() {
    driver = new FirefoxDriver();
  }

  @After
  public void teardown() {
    if (driver != null) {
      driver.quit();
    }
  }

  @Test
  public void test() {
    // Your test code here
  }
}

If you are using Maven you have to put at your pom.xml:

<dependency>
    <groupId>io.github.bonigarcia</groupId>
    <artifactId>webdrivermanager</artifactId>
    <version>4.3.1</version>
</dependency>

WebDriverManager does magic for you:

1. It checks for the latest version of the WebDriver binary
2. It downloads the WebDriver binary if it's not present on your system
3. It exports the required WebDriver Java environment variables needed by Selenium

So far, WebDriverManager supports Chrome, Opera, Internet Explorer, Microsoft Edge, PhantomJS, and Firefox.

This method will return true if any part of the element is visible on the page. It worked better in my case and may help someone else.

function isOnScreen(element) {
  var elementOffsetTop = element.offset().top;
  var elementHeight = element.height();

  var screenScrollTop = $(window).scrollTop();
  var screenHeight = $(window).height();

  var scrollIsAboveElement = elementOffsetTop + elementHeight - screenScrollTop >= 0;
  var elementIsVisibleOnScreen = screenScrollTop + screenHeight - elementOffsetTop >= 0;

  return scrollIsAboveElement && elementIsVisibleOnScreen;
}

In your src/main/resources put an application.properties or application.yml and put a server.contextPath in there.

server.contextPath=/your/context/here

When starting your application the application will be available at http://localhost:8080/your/context/here.

For a comprehensive list of properties to set see Appendix A. of the Spring Boot reference guide.

Instead of putting it in the application.properties you can also pass it as a system property when starting your application

java -jar yourapp.jar -Dserver.contextPath=/your/path/here

In March I made a deck presentation in slidify, Rmarkdown with impress.js which is a cool 3D framework. My index.Rmdheader looks like

Some issues appeared since I last worked on it (photos are no more in background, text it too large on my R plot) but it works fine on my local. Troubles come when I run it on RPubs.

$scope.$watch('age + name', function () {
  //called when name or age changed
});

for what it's worth, I experienced this same error when I had a typo (md4 instead of md5) in my pg_hba.conf file (/etc/postgresql/9.5/main/pg_hba.conf)

If you got here as I did, double-check that file once to make sure there isn't anything ridiculous in there.

You have to specify project_id:

reverse('edit_project', kwargs={'project_id':4})

Doc here

Using RIGHT is a good option but you can also do the following:

SUBSTRING(CAST((POWER(10, N) + value) AS NVARCHAR(N + 1)), 2, N)

where N is the total number of digits you want displayed. So for a 3-digit value with leading zeros (N = 3):

SUBSTRING(CAST((POWER(10, 3) + value) AS NVARCHAR(4)), 2, 3)

or alternately

SUBSTRING(CAST(1000 + value) AS NVARCHAR(4)), 2, 3)

What this is doing is adding the desired value to a power of 10 large enough to generate enough leading zeros, then chopping off the leading 1.

The advantage of this technique is that the result will always be the same length, allowing the use of SUBSTRING instead of RIGHT, which is not available in some query languages (like HQL).

Be careful with "/" and "\". Even on Windows the command should be in the form:

\i c:/1.sql

This was written quickly, and is neither pretty nor efficient (plus it autoboxes alot, converting between int and Integer is annoying!), but it works.

It probably breaks the rules since I'm creating my own objects but hey I'm doing this as a diversion from real work :)

This also assumes that the resultSet/table is completely read into some sort of structure before you start building Nodes, which wouldn't be the best solution if you have hundreds of thousands of rows.

public class Node {

    private Node parent = null;

    private List<Node> children;

    private String name;

    private int id = -1;

    public Node(Node parent, int id, String name) {
        this.parent = parent;
        this.children = new ArrayList<Node>();
        this.name = name;
        this.id = id;
    }

    public int getId() {
        return this.id;
    }

    public String getName() {
        return this.name;
    }

    public void addChild(Node child) {
        children.add(child);
    }

    public List<Node> getChildren() {
        return children;
    }

    public boolean isRoot() {
        return (this.parent == null);
    }

    @Override
    public String toString() {
        return "id=" + id + ", name=" + name + ", parent=" + parent;
    }
}

public class NodeBuilder {

    public static Node build(List<Map<String, String>> input) {

        // maps id of a node to it's Node object
        Map<Integer, Node> nodeMap = new HashMap<Integer, Node>();

        // maps id of a node to the id of it's parent
        Map<Integer, Integer> childParentMap = new HashMap<Integer, Integer>();

        // create special 'root' Node with id=0
        Node root = new Node(null, 0, "root");
        nodeMap.put(root.getId(), root);

        // iterate thru the input
        for (Map<String, String> map : input) {

            // expect each Map to have keys for "id", "name", "parent" ... a
            // real implementation would read from a SQL object or resultset
            int id = Integer.parseInt(map.get("id"));
            String name = map.get("name");
            int parent = Integer.parseInt(map.get("parent"));

            Node node = new Node(null, id, name);
            nodeMap.put(id, node);

            childParentMap.put(id, parent);
        }

        // now that each Node is created, setup the child-parent relationships
        for (Map.Entry<Integer, Integer> entry : childParentMap.entrySet()) {
            int nodeId = entry.getKey();
            int parentId = entry.getValue();

            Node child = nodeMap.get(nodeId);
            Node parent = nodeMap.get(parentId);
            parent.addChild(child);
        }

        return root;
    }
}

public class NodePrinter {

    static void printRootNode(Node root) {
        printNodes(root, 0);
    }

    static void printNodes(Node node, int indentLevel) {

        printNode(node, indentLevel);
        // recurse
        for (Node child : node.getChildren()) {

        }
    }

    static void printNode(Node node, int indentLevel) {
        StringBuilder sb = new StringBuilder();
        for (int i = 0; i < indentLevel; i++) {
            sb.append("\t");
        }
        sb.append(node);

        System.out.println(sb.toString());
    }

    public static void main(String[] args) {

        // setup dummy data
        List<Map<String, String>> resultSet = new ArrayList<Map<String, String>>();
        resultSet.add(newMap("1", "Node 1", "0"));
        resultSet.add(newMap("2", "Node 1.1", "1"));
        resultSet.add(newMap("3", "Node 2", "0"));
        resultSet.add(newMap("4", "Node 1.1.1", "2"));
        resultSet.add(newMap("5", "Node 2.1", "3"));
        resultSet.add(newMap("6", "Node 1.2", "1"));

        Node root = NodeBuilder.build(resultSet);
        printRootNode(root);

    }

    //convenience method for creating our dummy data
    private static Map<String, String> newMap(String id, String name, String parentId) {
        Map<String, String> row = new HashMap<String, String>();
        row.put("id", id);
        row.put("name", name);
        row.put("parent", parentId);
        return row;
    }
}

The only solution I've found (almost instantly after posting the question), is to loop through the array and use Object.assign()

Like this:

public duplicateArray() {
  let arr = [];
  this.content.forEach((x) => {
    arr.push(Object.assign({}, x));
  })
  arr.map((x) => {x.status = DEFAULT});
  return this.content.concat(arr);
}

I know this is not optimal. And I wonder if there's any better solutions.

thers is a simple way to create toggle button. I test it in vs2010. It's perfect.

ToolStripButton has a "Checked" property and a "CheckOnClik" property. You can use it to act as a toggle button

tbtnCross.CheckOnClick = true;

OR

    tbtnCross.CheckOnClick = false;
    tbtnCross.Click += new EventHandler(tbtnCross_Click);
    .....

    void tbtnCross_Click(object sender, EventArgs e)
    {
        ToolStripButton target = sender as ToolStripButton;
        target.Checked = !target.Checked;
    }

also, You can create toggle button list like this:

        private void Form1_Load(object sender, EventArgs e)
    {
        arrToolView[0] = tbtnCross;
        arrToolView[1] = tbtnLongtitude;
        arrToolView[2] = tbtnTerrain;
        arrToolView[3] = tbtnResult;
        for (int i = 0; i<arrToolView.Length; i++)
        {
            arrToolView[i].CheckOnClick = false;
            arrToolView[i].Click += new EventHandler(tbtnView_Click);
        }
        InitTree();
    }

    void tbtnView_Click(object sender, EventArgs e)
    {
        ToolStripButton target = sender as ToolStripButton;
        if (target.Checked) return;
        foreach (ToolStripButton btn in arrToolView)
        {
                btn.Checked = false;
                //btn.CheckState = CheckState.Unchecked;
        }
        target.Checked = true;
        target.CheckState = CheckState.Checked;

    }

Based on the documentation you should be able to use auto in combination with the preferred placement e.g. auto left

http://getbootstrap.com/javascript/#popovers: "When "auto" is specified, it will dynamically reorient the popover. For example, if placement is "auto left", the tooltip will display to the left when possible, otherwise it will display right."

I was trying to do the same thing and then realised that this functionality already existed.

There is a dummy solution I use it to abort all ajax requests. This solution is reload the whole page. This solution is good if you don't like to assign an ID to each ajax request, and if you make ajax requests inside for-loop. This will make sure all ajax requests are killed.

location.reload();

Solution for pulling Map using @Value from application.yml property coded as multiline

application.yml

other-prop: just for demo 

my-map-property-name: "{\
         key1: \"ANY String Value here\", \  
         key2: \"any number of items\" , \ 
         key3: \"Note the Last item does not have comma\" \
         }"

other-prop2: just for demo 2 

Here the value for our map property "my-map-property-name" is stored in JSON format inside a string and we have achived multiline using \ at end of line

myJavaClass.java

import org.springframework.beans.factory.annotation.Value;

public class myJavaClass {

@Value("#{${my-map-property-name}}") 
private Map<String,String> myMap;

public void someRandomMethod (){
    if(myMap.containsKey("key1")) {
            //todo...
    } }

}

More explanation

• \ in yaml it is Used to break string into multiline

• \" is escape charater for "(quote) in yaml string

• {key:value} JSON in yaml which will be converted to Map by @Value

• #{ } it is SpEL expresion and can be used in @Value to convert json int Map or Array / list Reference

A neat trick for fast rounding is to add .5 before you cast your decimal to an int.

decimal d = 10.1m;
d += .5m;
int i = (int)d;

Still leaves i=10, but

decimal d = 10.5m;
d += .5m;
int i = (int)d;

Would round up so that i=11.

Use shared variable to communicate. For example like this:

import multiprocessing


def worker(procnum, return_dict):
    """worker function"""
    print(str(procnum) + " represent!")
    return_dict[procnum] = procnum


if __name__ == "__main__":
    manager = multiprocessing.Manager()
    return_dict = manager.dict()
    jobs = []
    for i in range(5):
        p = multiprocessing.Process(target=worker, args=(i, return_dict))
        jobs.append(p)
        p.start()

    for proc in jobs:
        proc.join()
    print(return_dict.values())

[ stands for single dimension array
Ljava.lang.String stands for the string class (L followed by class/interface name)

Few Examples:

1. Class.forName("[D") -> Array of primitive double
2. Class.forName("[[Ljava.lang.String") -> Two dimensional array of strings.

List of notations:
Element Type : Notation
boolean : Z
byte : B
char : C
class or interface : Lclassname
double : D
float : F
int : I
long : J
short : S

With webdriver aka selenium2 you can use implicit wait configuration as mentionned on https://www.selenium.dev/documentation/en/webdriver/waits/#implicit-wait

Using Java:

WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.get("http://somedomain/url_that_delays_loading");
WebElement myDynamicElement = driver.findElement(By.id("myDynamicElement"));

Or using python:

from selenium import webdriver

ff = webdriver.Firefox()
ff.implicitly_wait(10) # seconds
ff.get("http://somedomain/url_that_delays_loading")
myDynamicElement = ff.find_element_by_id("myDynamicElement")

Simply do this:

IF EXISTS (SELECT * FROM tablename)
BEGIN
    DELETE from  tablename
    DBCC checkident ('tablename', reseed, 0)
END

This can happen when the system time changes while debugging or between debug sessions, be it programmatically, manually or by an external program.

ArrayList<String> arrayList = new ArrayList<String>();
Object[] objectList = arrayList.toArray();
String[] stringArray =  Arrays.copyOf(objectList,objectList.length,String[].class);

Using copyOf, ArrayList to arrays might be done also.

As someone who has been interested in this for a VERY LONG TIME. See from the manual:

$XDG_CONFIG_HOME/git/config - Second user-specific configuration file. If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/config will be used. Any single-valued variable set in this file will be overwritten by whatever is in ~/.gitconfig. It is a good idea not to create this file if you sometimes use older versions of Git, as support for this file was added fairly recently.

Which was only recently added. This dump is from 2.15.0.

Works for me.

As per @kexik's suggestion using the UNIX time function as below :

  time_t result = time(NULL);
  NSLog([NSString stringWithFormat:@"The current Unix epoch time is %d",(int)result]);

.As per my experience - don't use timeIntervalSince1970 , it gives epoch timestamp - number of seconds you are behind GMT.

There used to be a bug with [[NSDate date]timeIntervalSince1970] , it used to add/subtract time based on the timezone of the phone but it seems to be resolved now.

I try many things and finally found that the last parameter must be false and you must add <SCRIPT> tag to the java script :

string script = "< SCRIPT >alert('hello!');< /SCRIPT>";

ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), key, script, **false**);

Ubuntu 10.04 with openSSH

this is the exact usage:

ssh -v -i [yourkeypairfile] ec2-user@[yourdnsaddress]

for example:

ssh -v -i GSG_Keypair.pem [email protected]

above example was taken directly from the AWS tutorial for connecting to a Linux/UNIX machine at: http://docs.amazonwebservices.com/AWSEC2/latest/GettingStartedGuide/

ncdu (ncurses du)

This awesome CLI utility allows you to easily find the large files and directories (recursive total size) interactively.

For example, from inside the root of a well known open source project we do:

sudo apt install ncdu
ncdu

The outcome its:

Then, I enter down and right on my keyboard to go into the /drivers folder, and I see:

ncdu only calculates file sizes recursively once at startup for the entire tree, so it is efficient.

"Total disk usage" vs "Apparent size" is analogous to du, and I have explained it at: why is the output of `du` often so different from `du -b`

Tested in Ubuntu 16.04.

Ubuntu list root

You likely want:

ncdu --exclude-kernfs -x /

where:

• -x stops crossing of filesystem barriers
• --exclude-kernfs skips special filesystems like /sys

MacOS 10.15.5 list root

To properly list root / on that system, I also needed --exclude-firmlinks, e.g.:

brew install ncdu
cd /
ncdu --exclude-firmlinks

otherwise it seemed to go into some link infinite loop, likely due to: https://www.swiftforensics.com/2019/10/macos-1015-volumes-firmlink-magic.html

The things we learn for love.

ncdu non-interactive usage

Another cool feature of ncdu is that you can first dump the sizes in a JSON format, and later reuse them.

For example, to generate the file run:

ncdu -o ncdu.json

and then examine it interactively with:

ncdu -f ncdu.json

This is very useful if you are dealing with a very large and slow filesystem like NFS.

This way, you can first export only once, which can take hours, and then explore the files, quit, explore again, etc.

The output format is just JSON, so it is easy to reuse it with other programs as well, e.g.:

ncdu -o -  | python -m json.tool | less

reveals a simple directory tree data structure:

ser.read(64) should be ser.read(size=64); ser.read uses keyword arguments, not positional.

Also, you're reading from the port twice; what you probably want to do is this:

i=0
for modem in PortList:
    for port in modem:
        try:
            ser = serial.Serial(port, 9600, timeout=1)
            ser.close()
            ser.open()
            ser.write("ati")
            time.sleep(3)
            read_val = ser.read(size=64)
            print read_val
            if read_val is not '':
                print port
        except serial.SerialException:
            continue
        i+=1

Also, there was no place to put the proxy credentials, but it will prompt you for them.

IPython is basically the "recommended" Python shell, which provides extra features. There is no language called IPython.

I've been using Typescript in my current angular project for about a year and a half and while there are a few issues with definitions every now and then the DefinitelyTyped project does an amazing job at keeping up with the latest versions of most popular libraries.

Having said that there is a definite learning curve when transitioning from vanilla JavaScript to TS and you should take into account the ability of you and your team to make that transition. Also if you are going to be using angular 1.x most of the examples you will find online will require you to translate them from JS to TS and overall there are not a lot of resources on using TS and angular 1.x together right now.

If you plan on using angular 2 there are a lot of examples using TS and I think the team will continue to provide most of the documentation in TS, but you certainly don't have to use TS to use angular 2.

ES6 does have some nice features and I personally plan on getting more familiar with it but I would not consider it a production-ready language at this point. Mainly due to a lack of support by current browsers. Of course, you can write your code in ES6 and use a transpiler to get it to ES5, which seems to be the popular thing to do right now.

Overall I think the answer would come down to what you and your team are comfortable learning. I personally think both TS and ES6 will have good support and long futures, I prefer TS though because you tend to get language features quicker and right now the tooling support (in my opinion) is a little better.
