There are two general ways of doing that. You will either create a Domain Object Model of that XML file, take a look at this

and the second choice is using event driven parsing, which is an alternative to DOM xml representation. Imho you can find the best overall comparison of these two basic techniques here. Of course there are much more to know about processing xml, for instance if you are given XML schema definition (XSD), you could use JAXB.

ng g c component-name

For specify custom location: ng g c specific-folder/component-name

here component-name will be created inside specific-folder.

Similarl approach can be used for generating other components like directive, pipe, service, class, guard, interface, enum, module, etc.

The reason for this error is, the file which maven is trying to delete is being used by some process. One example of such process is Eclipse or any other IDE is doing validation on same project.

Please make sure that no validation running from eclipse or in any other IDE where project is open.

in any os

npm -g list

and thats it

This happened to me right after upgrading Firefox to version 51. After clearing the cache, the problem has gone.

For OpenJDK 8 on Linux see: https://askubuntu.com/questions/755853/how-to-install-jdk-sources

The way that worked for me is:

• The default src.zip is a symbolic link pointing to a non-existing folder ...
• sudo apt-get install openjdk-8-source this adds this folder
• locate "src.zip"
• Eclipse: Window --> Preferences --> Java --> "Installed JREs", edit and point to src.zip (or open any JRE class like for example HashMap and attach source)

You should now see the JavaDoc when opening JRE classes via Ctrl+Shift+t, previously this was not possible, Eclipse may have got a docs from the default URL on mouse over methods but this requires a stable internet connection.

The table normally contains multiple rows. Use a loop and use row.Field<string>(0) to access the value of each row.

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>("File");
}

You can also access it via index:

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>(0);
}

If you expect only one row, you can also use the indexer of DataRowCollection:

string file = dt.Rows[0].Field<string>(0); 

Since this fails if the table is empty, use dt.Rows.Count to check if there is a row:

if(dt.Rows.Count > 0)
    file = dt.Rows[0].Field<string>(0);

Follow up to accepted answer.

You need something other than CTRL-D to designate the end if using this in a script. Try this instead:

cat << EOF >> filename
This is text entered via the keyboard or via a script.
EOF

This will append text to the stated file (not including "EOF").

It utilizes a here document (or heredoc).

However if you need sudo to append to the stated file, you will run into trouble utilizing a heredoc due to I/O redirection if you're typing directly on the command line.

This variation will work when you are typing directly on the command line:

sudo sh -c 'cat << EOF >> filename
This is text entered via the keyboard.
EOF'

Or you can use tee instead to avoid the command line sudo issue seen when using the heredoc with cat:

tee -a filename << EOF
This is text entered via the keyboard or via a script.
EOF

Fastest solution to render DOM from string:

let render = (relEl, tpl, parse = true) => {
  if (!relEl) return;
  const range = document.createRange();
  range.selectNode(relEl);
  const child = range.createContextualFragment(tpl);
  return parse ? relEl.appendChild(child) : {relEl, el};
};

And here u can check performance for DOM manipulation React vs native JS

Now u can simply use:

let element = render(document.body, `
<div style="font-size:120%;line-height:140%">
  <p class="bold">New DOM</p>
</div>
`);

And of course in near future u use references from memory cause var "element" is your new created DOM in your document.

And remember "innerHTML=" is very slow :/

Whenever you access an Object (not being a String) in a String context then the toString() is called under the covers by the compiler.

This is why

Map map = new HashMap();
System.out.println("map=" + map);

works, and by overriding the standard toString() from Object in your own classes, you can make your objects useful in String contexts too.

(and consider it a black box! Never, ever use the contents for anything else than presenting to a human)

I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

If you need to call plot multiply times, you can also use the "label" argument:

ax = df1.plot(label='df1', y='y_var')
ax = df2.plot(label='df2', y='y_var')

While this is not the case in the OP question, this can be helpful if the DataFrame is in long format and you use groupby before plotting.

I know this is an old post and has been answered many times. I too was wondering if JavaScript had a function that would do this. I was doing some math programming and needed to concatenate two numbers.

So the what if I needed to combine two numbers 17 and 29. Sure I can turn them into strings and concatenate them then turn the new string back into a number. That seems to work pretty well and I can go on with my code, but lets take a look here and try to figure out what is really happening here.

What are we doing to these two numbers, how do we take 17 and 29 and turn it into one thousand seven hundred and twenty-nine? Well we can multiply 17 by 100 then add 29. And how about 172 and 293 to get one hundred seventy-two thousand two hundred and ninety-three? Multiply 172 by 1000 and add 293. But what about only 2 and 9? Multiply 2 by 10 then add 9 to get 29.

So hopefully by now a pattern should be apparent to you. We can devise a math formula to do this calculation for us rather than just using strings. To concatenate any two numbers, a and b, we need to take the product of a and 10 to the power of length b then add b.

So how do we get the length of number b? Well, we could turn b into a string and get the length property of it.

    a * Math.pow(10, new String(b).length) + b;

But there has to be a better way to do this without strings, right? Yes there is.

For any two numbers, a and b, with any base B. We are going to multiply a by base B to the power of length b (using log base of b then flooring it to get the nearest whole number then adding 1 to it) then adding b.

So now our code looks like this:

    a * Math.pow(10, Math.floor(Math.log10(b)) + 1) + b;

But wait, what if I wanted to do this in base 2 or base 8? How can I do that? We can't use our formula that we just created with any other base but base 10. The JavaScript Math object already has built-in functions for base 10 and 2 (just Math.log), but how do we get log functions for any other base? We divide the log of b by the log of base. Math.log(b) / Math.log(base).

So now we have our fully functioning math based code for concatenating two numbers:

    function concatenate(a, b, base) {
        return a * Math.pow(base, Math.floor(Math.log(b) / Math.log(base)) + 1) + b;
    }
    var a = 17, var b = 29;
    var concatenatedNumber = concatenate(a, b, 10);
    // concatenatedNumber = 1729

If you knew you were only going to be doing base 10 math, you could add a check for base is undefined then set base = 10:

    function concatenate(a, b, base) {
        if(typeof base == 'undefined') {
            base = 10;
        }
        return a * Math.pow(base, Math.floor(Math.log(b) / Math.log(base)) + 1) + b;
    }

    var a = 17, b = 29;
    var newNumber = concatenate(a, b); // notice I did not use the base argument
    // newNumber = 1729

To make it easier for me, I used the prototype to add the function to the Number object:

    Number.prototype.concatenate = function(b, base) {
        if(typeof base == 'undefined') {
                base = 10;
        }
        return this * Math.pow(base, Math.floor(Math.log(b) / Math.log(base)) + 1) + b;
    };
    var a = 17;
    var newNumber = a.concatenate(29);
    // newNumber = 1729

if you need to add a date-time to your backup file name (Centos7) use the following:

/usr/bin/mysqldump -u USER -pPASSWD DBNAME | gzip > ~/backups/db.$(date +%F.%H%M%S).sql.gz

this will create the file: db.2017-11-17.231537.sql.gz

This:

\d+

should work

Edit, no clue why I added the "+", without it works just as fine.

The exact answer to the question is: yes, you can use an arbitrary value for the boundary parameter, given it does not exceed 70 bytes in length and consists only of 7-bit US-ASCII (printable) characters.

If you are using one of multipart/* content types, you are actually required to specify the boundary parameter in the Content-Type header, otherwise the server (in the case of an HTTP request) will not be able to parse the payload.

You probably also want to set the charset parameter to UTF-8 in your Content-Type header, unless you can be absolutely sure that only US-ASCII charset will be used in the payload data.

A few relevant excerpts from the RFC2046:

• 4.1.2. Charset Parameter:

  Unlike some other parameter values, the values of the charset parameter are NOT case sensitive. The default character set, which must be assumed in the absence of a charset parameter, is US-ASCII.

• 5.1. Multipart Media Type

  As stated in the definition of the Content-Transfer-Encoding field [RFC 2045], no encoding other than "7bit", "8bit", or "binary" is permitted for entities of type "multipart". The "multipart" boundary delimiters and header fields are always represented as 7bit US-ASCII in any case (though the header fields may encode non-US-ASCII header text as per RFC 2047) and data within the body parts can be encoded on a part-by-part basis, with Content-Transfer-Encoding fields for each appropriate body part.

  The Content-Type field for multipart entities requires one parameter, "boundary". The boundary delimiter line is then defined as a line consisting entirely of two hyphen characters ("-", decimal value 45) followed by the boundary parameter value from the Content-Type header field, optional linear whitespace, and a terminating CRLF.

  Boundary delimiters must not appear within the encapsulated material, and must be no longer than 70 characters, not counting the two leading hyphens.

  The boundary delimiter line following the last body part is a distinguished delimiter that indicates that no further body parts will follow. Such a delimiter line is identical to the previous delimiter lines, with the addition of two more hyphens after the boundary parameter value.

Here is an example using an arbitrary boundary:

Content-Type: multipart/form-data; charset=utf-8; boundary="another cool boundary"

--another cool boundary
Content-Disposition: form-data; name="foo"

bar
--another cool boundary
Content-Disposition: form-data; name="baz"

quux
--another cool boundary--

This worked for me (win10), place before you import keras:

import os
os.environ['CUDA_VISIBLE_DEVICES'] = '-1'

$('.some_selector').attr('disabled', true);

For those who don't want to use HTML agility pack and want to get HtmlDocument from string using native .net code only here is a good article on how to convert string to HtmlDocument

Here is the code block to use

public System.Windows.Forms.HtmlDocument GetHtmlDocument(string html)
        {
            WebBrowser browser = new WebBrowser();
            browser.ScriptErrorsSuppressed = true;
            browser.DocumentText = html;
            browser.Document.OpenNew(true);
            browser.Document.Write(html);
            browser.Refresh();
            return browser.Document;
        }

Do the following, download SQLLite Database Browser from here:

Locate your db. file in your phone.

Then, as soon you install the program go to: "Browse Data", you will see all the SMS there!!

You can actually export the data to an excel file or SQL.

This is short, yet efficient and proven approach:

location ~ (patternOne|patternTwo){ #rules etc. }

So one can easily have multiple patterns with simple pipe syntax pointing to the same location block / rules.

foreach loop is faster than array_merge to append values to an existing array, so choose the loop instead if you want to add an array to the end of another.

// Create an array of arrays
$chars = [];
for ($i = 0; $i < 15000; $i++) {
    $chars[] = array_fill(0, 10, 'a');
}

// test array_merge
$new = [];
$start = microtime(TRUE);
foreach ($chars as $splitArray) {
    $new = array_merge($new, $splitArray);
}
echo microtime(true) - $start; // => 14.61776 sec

// test foreach
$new = [];
$start = microtime(TRUE);
foreach ($chars as $splitArray) {
    foreach ($splitArray as $value) {
        $new[] = $value;
    }
}
echo microtime(true) - $start; // => 0.00900101 sec
// ==> 1600 times faster

You can use

public List<E> addToListStart(List<E> list, E obj){
list.add(0,obj);
return (List<E>)list;

}

Change E with your datatype

If deleting the oldest element is necessary then you can add:

list.remove(list.size()-1); 

before return statement. Otherwise list will add your object at beginning and also retain oldest element.

This will delete last element in list.

If you were to use the C library then this could be done:

time_t t;
struct tm * timeinfo;

time (&t);
timeinfo = localtime (&t);

NSLog(@"Hour: %d Minutes: %d", timeinfo->tm_hour, timeinfo->tm_min);

And using Swift:

var t = time_t()
time(&t)
let x = localtime(&t)

println("Hour: \(x.memory.tm_hour) Minutes: \(x.memory.tm_min)")

For further guidance see: http://www.cplusplus.com/reference/ctime/localtime/

Create a new column with the desired column name: COLNew.

ALTER TABLE {tableName} ADD COLUMN COLNew {type};

Copy contents of old column COLOld to new column COLNew.

INSERT INTO {tableName} (COLNew) SELECT {COLOld} FROM {tableName}

Note: brackets are necessary in above line.

wrap your entire code block in this:

//<![CDATA[

//code here

//]]>

also make sure to specify the type of script to be text/javascript

try that and let me know how it goes

Just write this simple line of code :-

button.performClick();

where button is the reference variable of Button class and defined as follows:-

private Button buttonToday ;
buttonToday = (Button) findViewById(R.id.buttonToday);

That's it.

DecimalFormat df=new DecimalFormat("0.00");

Use this code to get exact two decimal points. Even if the value is 0.0 it will give u 0.00 as output.

Instead if you use:

DecimalFormat df=new DecimalFormat("#.00");  

It wont convert 0.2659 into 0.27. You will get an answer like .27.

Sure you can simply use two sliders overlaying each other and add a bit of javascript (actually not more than 5 lines) that the selectors are not exceeding the min/max values (like in @Garys) solution.

Attached you'll find a short snippet adapted from a current project including some CSS3 styling to show what you can do (webkit only). I also added some labels to display the selected values.

It uses JQuery but a vanillajs version is no magic though.

@Update: The code below was just a proof of concept. Due to many requests I've added a possible solution for Mozilla Firefox (without changing the original code). You may want to refractor the code below before using it.

    (function() {

        function addSeparator(nStr) {
            nStr += '';
            var x = nStr.split('.');
            var x1 = x[0];
            var x2 = x.length > 1 ? '.' + x[1] : '';
            var rgx = /(\d+)(\d{3})/;
            while (rgx.test(x1)) {
                x1 = x1.replace(rgx, '$1' + '.' + '$2');
            }
            return x1 + x2;
        }

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get(); 

For React you must use it's per-define keywords to define html attributes.

class -> className

is used and

for -> htmlFor

is used, as react is case sensitive make sure you must follow small and capital as required.

pscp and psftp are very customizable(options) and light weight. Open source to boot.

you can make use of the below code for sorting in descending order and storing to a dictionary:

        listname = []  
        for key, value in sorted(dictionaryName.iteritems(), key=lambda (k,v): (v,k),reverse=True):  
            diction= {"value":value, "key":key}  
            listname.append(diction)

Simple using html like this downloads the file mentioned using static keyword

<a href="{% static 'bt.docx' %}" class="btn btn-secondary px-4 py-2 btn-sm">Download CV</a>

This is the way that I have approached.

public class AppFCMService extends FirebaseMessagingService {

    private final static String TAG = "FCM Message";
    String notify, requstId, Notification;
    PendingIntent pendingIntent;

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
        //split string and getting order id from notification
        String Str = remoteMessage.getNotification().getBody();
        String[] tmp;
        tmp = Str.split(" ");
        String temp1 = tmp[0];
        String temp2 = tmp[1];
        String id = tmp[2];
        notify = temp1 + " " + temp2;
        requstId = id;
        showNotification(remoteMessage.getNotification().getBody());
    }

    private void showNotification(String messageBody) {
        // check whether session has been initiated or not
        if (new SessionHelper(getApplicationContext()).isLoggedIn()) {

            if (notify.equalsIgnoreCase("Travel request")) {

                Intent intent = new Intent(this, ViewTravelDetailsActivity.class);
                intent.putExtra("TravelRequestID", requstId);
                intent.putExtra("BackPress", "Notify");
                pendingIntent = PendingIntent.getActivity(this, 0, intent,
                        PendingIntent.FLAG_ONE_SHOT);

            } else if (notify.equalsIgnoreCase("Timesheet replied")) {

                Intent intent = new Intent(this, ViewReplyActivity.class);
                intent.putExtra("timesheetActivityID", requstId);
                intent.putExtra("BackPress", "Notify");
                intent.putExtra("RealmData", "DeleteRealm");
                intent.putExtra("isToday", "true");
                pendingIntent = PendingIntent.getActivity(this, 0, intent,
                        PendingIntent.FLAG_ONE_SHOT);
            } else {

                Intent intent = new Intent(this, Dashboard.class);
                intent.putExtra("timesheetActivityID", requstId);
                pendingIntent = PendingIntent.getActivity(this, 0, intent,
                        PendingIntent.FLAG_ONE_SHOT);
            }
        } else {

            Intent intent = new Intent(this, LoginActivity.class);
            intent.putExtra("timesheetActivityID", requstId);
            pendingIntent = PendingIntent.getActivity(this, 0, intent,
                    PendingIntent.FLAG_ONE_SHOT);
        }

        Bitmap notifyImage = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(notifyImage)
                .setColor(Color.parseColor("#FFE74C3C"))
                .setContentTitle("TEST")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);
        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        notificationManager.notify(0, notificationBuilder.build());
    }
}

you can put the input inside a form like this:-

<script>
    $(document).ready(function(){
        $(document).on('click','#send', function(){
            $('#hid').val(data)
            document.forms["myForm"].submit();
        })
    })
</script>

<form id="myForm" action="/request_page url/" method="post">
    <input type="hidden" id="hid" name="hid"/>
</form>
<div id="send">Send Data</div>

To walk through the @INC directory trees without using an external program like ls(1), one could use the File::Find::Rule module, which has a nice declarative interface.

Also, you want to filter out duplicates in case previous Perl versions contain the same modules. The code to do this looks like:

#! /usr/bin/perl -l

use strict;
use warnings;
use File::Find::Rule;

my %seen;
for my $path (@INC) {
    for my $file (File::Find::Rule->name('*.pm')->in($path)) {
        my $module = substr($file, length($path)+1);
        $module =~ s/.pm$//;
        $module =~ s{[\\/]}{::}g;
        print $module unless $seen{$module}++;
    }
}

At the end of the run, you also have all your module names as keys in the %seen hash. The code could be adapted to save the canonical filename (given in $file) as the value of the key instead of a count of times seen.

With string type columns like character(2) (as you mentioned later), the displayed concatenation just works because, quoting the manual:

[...] the string concatenation operator (||) accepts non-string input, so long as at least one input is of a string type, as shown in Table 9.8. For other cases, insert an explicit coercion to text [...]

Bold emphasis mine. The 2nd example (select a||', '||b from foo) works for any data types since the untyped string literal ', ' defaults to type text making the whole expression valid in any case.

For non-string data types, you can "fix" the 1st statement by casting at least one argument to text. (Any type can be cast to text):

SELECT a::text || b AS ab FROM foo;

Judging from your own answer, "does not work" was supposed to mean "returns NULL". The result of anything concatenated to NULL is NULL. If NULL values can be involved and the result shall not be NULL, use concat_ws() to concatenate any number of values (Postgres 9.1 or later):

SELECT concat_ws(', ', a, b) AS ab FROM foo;

Or concat() if you don't need separators:

SELECT concat(a, b) AS ab FROM foo;

No need for type casts here since both functions take "any" input and work with text representations.

More details (and why COALESCE is a poor substitute) in this related answer:

• Combine two columns and add into one new column

Regarding update in the comment

+ is not a valid operator for string concatenation in Postgres (or standard SQL). It's a private idea of Microsoft to add this to their products.

There is hardly any good reason to use character(n) (synonym: char(n)). Use text or varchar. Details:

• Any downsides of using data type "text" for storing strings?
• Best way to check for "empty or null value"

Leading on from Andrew's answer with regards to c#2 and c#3 ... you can also do them inline for a one off search function (see below).

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<int> list = new List<int> { 1, 2, 3 };

        List<int> newList = list.FindAll(delegate(int arg)
                           {
                               return arg> 2;
                           });
    }
}

Hope this helps.

you can also set environment variables in the script itself, rather than passing region_name parameter

os.environ['AWS_DEFAULT_REGION'] = 'your_region_name'

case sensitivity may matter.

First we can define a new operator,

"%ni%" = Negate( "%in%" )

Then, its like x not in remove

x <- 1:10
remove <- c(2,3,5)
x <- x[ x %ni% remove ]

or why to go for remove, go directly

x <- x[ x %ni% c(2,3,5)]

Download and install SAP Crystal Reports Runtime engine for .net (32 bit or 64 bit) depending on your os version. Should work there after

You have to download the whole project with either "Clone to desktop" button that will use native github program or "Download as zip".

And then search that folder in downloaded project.

private List<String[]> addresses = new ArrayList<String[]>();

this will work defenitely...

In Java there is nothing at language level similar to ref. In Java there is only passing by value semantic

For the sake of curiosity you can implement a ref-like semantic in Java simply wrapping your objects in a mutable class:

public class Ref<T> {

    private T value;

    public Ref(T value) {
        this.value = value;
    }

    public T get() {
        return value;
    }

    public void set(T anotherValue) {
        value = anotherValue;
    }

    @Override
    public String toString() {
        return value.toString();
    }

    @Override
    public boolean equals(Object obj) {
        return value.equals(obj);
    }

    @Override
    public int hashCode() {
        return value.hashCode();
    }
}

testcase:

public void changeRef(Ref<String> ref) {
    ref.set("bbb");
}

// ...
Ref<String> ref = new Ref<String>("aaa");
changeRef(ref);
System.out.println(ref); // prints "bbb"

Given the following sample

myData <- data.frame(A=rep(1:2, 3), B=rep(1:3, 2), Pulse=20:25)  

then

myData$A <-as.factor(myData$A)
myData$B <-as.factor(myData$B)

or you could select your columns altogether and wrap it up nicely:

# select columns
cols <- c("A", "B")
myData[,cols] <- data.frame(apply(myData[cols], 2, as.factor))

levels(myData$A) <- c("long", "short")
levels(myData$B) <- c("1kg", "2kg", "3kg")

To obtain

> myData
      A   B Pulse
1  long 1kg    20
2 short 2kg    21
3  long 3kg    22
4 short 1kg    23
5  long 2kg    24
6 short 3kg    25

Here is what I had and what caused my "incomplete type error":

#include "X.h" // another already declared class
class Big {...} // full declaration of class A

class Small : Big {
    Small() {}
    Small(X); // line 6
}
//.... all other stuff

What I did in the file "Big.cpp", where I declared the A2's constructor with X as a parameter is..

Big.cpp

Small::Big(X my_x) { // line 9 <--- LOOK at this !
}

I wrote "Small::Big" instead of "Small::Small", what a dumb mistake.. I received the error "incomplete type is now allowed" for the class X all the time (in lines 6 and 9), which made a total confusion..

Anyways, that is where a mistake can happen, and the main reason is that I was tired when I wrote it and I needed 2 hours of exploring and rewriting the code to reveal it.

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

The answer I got is that variables and subqueries will not work and we have to user dynamic SQL script. The following works:

DECLARE @SQL VARCHAR(4000)
SET @SQL = 'ALTER TABLE dbo.Student DROP CONSTRAINT |ConstraintName| '

SET @SQL = REPLACE(@SQL, '|ConstraintName|', ( SELECT   name
                                               FROM     sysobjects
                                               WHERE    xtype = 'PK'
                                                        AND parent_obj =        OBJECT_ID('Student')))

EXEC (@SQL)

Classic case for a recursive solution. Here's mine:

class JsonFormatter {
    public static function prettyPrint(&$j, $indentor = "\t", $indent = "") {
        $inString = $escaped = false;
        $result = $indent;

        if(is_string($j)) {
            $bak = $j;
            $j = str_split(trim($j, '"'));
        }

        while(count($j)) {
            $c = array_shift($j);
            if(false !== strpos("{[,]}", $c)) {
                if($inString) {
                    $result .= $c;
                } else if($c == '{' || $c == '[') {
                    $result .= $c."\n";
                    $result .= self::prettyPrint($j, $indentor, $indentor.$indent);
                    $result .= $indent.array_shift($j);
                } else if($c == '}' || $c == ']') {
                    array_unshift($j, $c);
                    $result .= "\n";
                    return $result;
                } else {
                    $result .= $c."\n".$indent;
                } 
            } else {
                $result .= $c;
                $c == '"' && !$escaped && $inString = !$inString;
                $escaped = $c == '\\' ? !$escaped : false;
            }
        }

        $j = $bak;
        return $result;
    }
}

Usage:

php > require 'JsonFormatter.php';
php > $a = array('foo' => 1, 'bar' => 'This "is" bar', 'baz' => array('a' => 1, 'b' => 2, 'c' => '"3"'));
php > print_r($a);
Array
(
    [foo] => 1
    [bar] => This "is" bar
    [baz] => Array
        (
            [a] => 1
            [b] => 2
            [c] => "3"
        )

)
php > echo JsonFormatter::prettyPrint(json_encode($a));
{
    "foo":1,
    "bar":"This \"is\" bar",
    "baz":{
        "a":1,
        "b":2,
        "c":"\"3\""
    }
}

Cheers

I'm not entirely sure of the general purpose of the function, but you could always do this:

function getMachine(color, qty) {
    var retval;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            retval = thisArray[3];
            return false;
        }
    });
    return retval;
}

var retval = getMachine(color, qty);

You can use store object that is returned from createStore function (which should be already used in your code in app initialization). Than you can use this object to get current state with store.getState() method or store.subscribe(listener) to subscribe to store updates.

You can even save this object to window property to access it from any part of application if you really want it (window.store = store)

More info can be found in the Redux documentation .

You could use a dictionary approach like this one. Basically you assign the value you want to be distinct as a key in the "dictionary" (here we use an array as an object to avoid dictionary-mode). If the key did not exist then you add that value as distinct.

Here is a working demo:

var array = [{"name":"Joe", "age":17}, {"name":"Bob", "age":17}, {"name":"Carl", "age": 35}];_x000D_
var unique = [];_x000D_
var distinct = [];_x000D_
for( let i = 0; i < array.length; i++ ){_x000D_
  if( !unique[array[i].age]){_x000D_
    distinct.push(array[i].age);_x000D_
    unique[array[i].age] = 1;_x000D_
  }_x000D_
}_x000D_
var d = document.getElementById("d");_x000D_
d.innerHTML = "" + distinct;

<div id="d"></div>

This will be O(n) where n is the number of objects in array and m is the number of unique values. There is no faster way than O(n) because you must inspect each value at least once.

The previous version of this used an object, and for in. These were minor in nature, and have since been minorly updated above. However, the reason for a seeming advance in performance between the two versions in the original jsperf was due to the data sample size being so small. Thus, the main comparison in the previous version was looking at the difference between the internal map and filter use versus the dictionary mode lookups.

I have updated the code above, as noted, however, I have also updated the jsperf to look through 1000 objects instead of 3. 3 overlooked many of the performance pitfalls involved (obsolete jsperf).

Performance

https://jsperf.com/filter-vs-dictionary-more-data When I ran this dictionary was 96% faster.

For Electron modules, install electron-rebuild.

Format:
electron-rebuild -o <module_name> -v <electron version>

Example:
electron-rebuild -o myaddon -v 9.0.0-beta.6

Specify the same version that you have installed in the current directory

You might have this experience where a standard node-gyp build would report as 64, then a basic electron-rebuild would report 76, not until you add -v with exact version it bumps to actual version 80 (for 9.0.0-beta.6)

SELECT * FROM MyTable WHERE Column1 Like "*word*"

This will display all the records where column1 has a partial value contains word.

See my answer to "What is a monad?"

It begins with a motivating example, works through the example, derives an example of a monad, and formally defines "monad".

It assumes no knowledge of functional programming and it uses pseudocode with function(argument) := expression syntax with the simplest possible expressions.

This C++ program is an implementation of the pseudocode monad. (For reference: M is the type constructor, feed is the "bind" operation, and wrap is the "return" operation.)

I guess the answer you need is referenced here Python sets are not json serializable

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.

In the XML file set the android:checkedButton field in your RadioGroup, with the id of your default RadioButton:

<RadioGroup
    ....
    android:checkedButton="@+id/button_1">

    <RadioButton
        android:id="@+id/button_1"
        ...../>

    <RadioButton
        android:id="@+id/button_2"
        ...../>

    <RadioButton
        android:id="@+id/button_3"
        ...../>
</RadioGroup>

Be careful with some answers...

UPDATE 2019-0829, I also included Microsoft decompiled code which should be far better than mine.

1 - You could easily represent any number with 15 significatives digits in memory with a double. See Wikipedia.

2 - The problem come from calculation of floating numbers where you could loose some precision. I mean that a number like .1 could become something like .1000000000000001 ==> after calculation. When you do some calculation, results could be truncated in order to be represented in a double. That truncation brings the error you could get.

3 - To prevent the problem when comparing double values, people introduce an error margin often called epsilon. If 2 floating numbers only have a contextual epsilon as difference, then they are considered equals. double.Epsilon is the smallest number between a double value and its neigbor (next or previous) value.

4 - The difference betwen 2 double values could be more than double.epsilon. The difference between the real double value and the one computed depends on how many calculation you have done and which ones. Many peoples think that it is always double.Epsilon but they are really wrong. To have a great answer please see: Hans Passant answer. The epsilon is based on your context where it depends on the biggest number you reach during your calculation and on the number of calculation you are doing (truncation error accumulate).

5 - This is the code that I use. Be careful that I use my epsilon only for few calculations. Otherwise I multiply my epsilon by 10 or 100.

6 - As noted by SvenL, it is possible that my epsilon is not big enough. I suggest to read SvenL comment. Also, perhaps "decimal" could do the job for your case?

This provides you to retrieve information from your URI strings

$this->uri->segment(n); // n=1 for controller, n=2 for method, etc

Consider this example:

http://example.com/index.php/controller/action/1stsegment/2ndsegment

it will return

$this->uri->segment(1); // controller
$this->uri->segment(2); // action
$this->uri->segment(3); // 1stsegment
$this->uri->segment(4); // 2ndsegment

You want $.param(): http://api.jquery.com/jQuery.param/

Specifically, you want this:

var data = { one: 'first', two: 'second' };
var result = $.param(data);

When given something like this:

{a: 1, b : 23, c : "te!@#st"}

$.param will return this:

a=1&b=23&c=te!%40%23st

for (Object object : someList) {

   // do whatever
}  throws the null pointer exception.

The __init__.py file makes Python treat directories containing it as modules.

Furthermore, this is the first file to be loaded in a module, so you can use it to execute code that you want to run each time a module is loaded, or specify the submodules to be exported.

Try moving the order by clause outside sub select and add the order by field in sub select

SELECT * FROM 

(SELECT COUNT(1) ,refKlinik_id FROM Seanslar WHERE MONTH(tarihi) = 4 GROUP BY refKlinik_id)
as dorduncuay 

ORDER BY refKlinik_id 

yes... This is for each loop in java.

Generally this loop is become useful when you are retrieving data or object from the database.

Syntex :

for(Object obj : Collection obj)
{
     //Code enter code here
}

Example :

for(User user : userList)
{
     System.out.println("USer NAme :" + user.name);
   // etc etc
}

This is for each loop.

it will incremental by automatically. one by one from collection to USer object data has been filled. and working.

Alternatively you can use the Protected Attributes gem, however this defeats the purpose of requiring strong params. However if you're upgrading an older app, Protected Attributes does provide an easy pathway to upgrade until such time that you can refactor the attr_accessible to strong params.

Add class text-center to your column:

<div class="col text-center">
I am centered
</div>

collection : A collection(with small 'c') represents a group of objects/elements.

Collection : The root interface of Java Collections Framework.

Collections : A utility class that is a member of the Java Collections Framework.

I got this error message when "/" from my URL is missing . Hope this help someone.

ex: actual URL is "https://www.myweb.com/login" .My URL which "https://www.myweb.comlogin" caused this error

You can use getChanges() on Eloquent model even after persisting.

If you're on OS X, you can change line endings in XCode by opening the file and selecting the

View -> Text -> Line Endings -> Unix

menu item, then Save. This is for XCode 3.x. Probably something similar in XCode 4.

The error complains about localhost rather than permissions and the current practice in MySQL is to have a bind-address specifying localhost only in a configuration file.

So I don't think it's a password problem - except that you say you 'unzipped' MySQL.

Is that enough installation? What did you download?

Was there any installation step which allowed you to define a root password?

And, as NawaMan said, is the server running?

I don't know about targeting iOS as a whole, but to target iOS Safari specifically:

@supports (-webkit-touch-callout: none) {
   /* CSS specific to iOS devices */ 
}

@supports not (-webkit-touch-callout: none) {
   /* CSS for other than iOS devices */ 
}

Apparently as of iOS 13 -webkit-overflow-scrolling no longer responds to @supports, but -webkit-touch-callout still does. Of course that could change in the future...

You should use partial views. I use the following approach:

Use a view model so you're not passing your domain models to your views:

public class EditPersonViewModel
{
    public int Id { get; set; }   // this is only used to retrieve record from Db
    public string Name { get; set; }
    public string Age { get; set; }
}

In your PersonController:

[HttpGet] // this action result returns the partial containing the modal
public ActionResult EditPerson(int id)
{  
    var viewModel = new EditPersonViewModel();
    viewModel.Id = id;
    return PartialView("_EditPersonPartial", viewModel);
}

[HttpPost] // this action takes the viewModel from the modal
public ActionResult EditPerson(EditPersonViewModel viewModel)
{
    if (ModelState.IsValid)
    {
        var toUpdate = personRepo.Find(viewModel.Id);
        toUpdate.Name = viewModel.Name;
        toUpdate.Age = viewModel.Age;
        personRepo.InsertOrUpdate(toUpdate);
        personRepo.Save();
        return View("Index");
    }
}

Next create a partial view called _EditPersonPartial. This contains the modal header, body and footer. It also contains the Ajax form. It's strongly typed and takes in our view model.

@model Namespace.ViewModels.EditPersonViewModel
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    <h3 id="myModalLabel">Edit group member</h3>
</div>
<div>
@using (Ajax.BeginForm("EditPerson", "Person", FormMethod.Post,
                    new AjaxOptions
                    {
                        InsertionMode = InsertionMode.Replace,
                        HttpMethod = "POST",
                        UpdateTargetId = "list-of-people"
                    }))
{
    @Html.ValidationSummary()
    @Html.AntiForgeryToken()
    <div class="modal-body">
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Name)
        @Html.Bootstrap().ControlGroup().TextBoxFor(x => x.Age)
    </div>
    <div class="modal-footer">
        <button class="btn btn-inverse" type="submit">Save</button>
    </div>
}

Now somewhere in your application, say another partial _peoplePartial.cshtml etc:

<div>
   @foreach(var person in Model.People)
    {
        <button class="btn btn-primary edit-person" data-id="@person.PersonId">Edit</button>
    }
</div>
// this is the modal definition
<div class="modal hide fade in" id="edit-person">
    <div id="edit-person-container"></div>
</div>

    <script type="text/javascript">
    $(document).ready(function () {
        $('.edit-person').click(function () {
            var url = "/Person/EditPerson"; // the url to the controller
            var id = $(this).attr('data-id'); // the id that's given to each button in the list
            $.get(url + '/' + id, function (data) {
                $('#edit-person-container').html(data);
                $('#edit-person').modal('show');
            });
        });
     });
   </script>

Since not all versions of jQuery are created equal, you may run into the same issue I did which means calling $("#item").removeClass(); does not actually remove the class. (Probably a bug)

A more reliable method is to simply use raw JavaScript and remove the class attribute altogether.

document.getElementById("item").removeAttribute("class");

You can use the following

/*eslint-disable */

//suppress all warnings between comments
alert('foo');

/*eslint-enable */

Which is slightly buried the "configuring rules" section of the docs;

To disable a warning for an entire file, you can include a comment at the top of the file e.g.

/*eslint eqeqeq:0*/

Update

ESlint has now been updated with a better way disable a single line, see @goofballLogic's excellent answer.

I think you can try this:

<a th:href="${'/category/edit/' + {category.id}}">view</a>

Or if you have "idCategory" this:

<a th:href="${'/category/edit/' + {category.idCategory}}">view</a>

Change that import to

from matplotlib.pyplot import *

Note that this style of imports (from X import *) is generally discouraged. I would recommend using the following instead:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4])

Similarly using rlang:

eval(parse_expr("5+5"))

    public static KeyValuePair<object, object > Cast<K, V>(this KeyValuePair<K, V> kvp)
    {
        return new KeyValuePair<object, object>(kvp.Key, kvp.Value);
    }

    public static KeyValuePair<T, V> CastFrom<T, V>(Object obj)
    {
        return (KeyValuePair<T, V>) obj;
    }

    public static KeyValuePair<object , object > CastFrom(Object obj)
    {
        var type = obj.GetType();
        if (type.IsGenericType)
        {
            if (type == typeof (KeyValuePair<,>))
            {
                var key = type.GetProperty("Key");
                var value = type.GetProperty("Value");
                var keyObj = key.GetValue(obj, null);
                var valueObj = value.GetValue(obj, null);
                return new KeyValuePair<object, object>(keyObj, valueObj);
            }
        }
        throw new ArgumentException(" ### -> public static KeyValuePair<object , object > CastFrom(Object obj) : Error : obj argument must be KeyValuePair<,>");
    }

From the OP:

Instead of converting my whole Dictionary, i decided to keep my obj dynamic the whole time. When i access the keys and values of my Dictionary with a foreach later, i use foreach(dynamic key in obj.Keys) and convert the keys and values to strings simply.

The maven dependency plugin can potentially solve your problem.

If you have a pom with all your project dependencies specified, all you would need to do is run

mvn dependency:copy-dependencies

and you will find the target/dependencies folder filled with all the dependencies, including transitive.

Adding Gustavo's answer from below: To download the dependency sources, you can use

mvn dependency:copy-dependencies -Dclassifier=sources

(via Apache Maven Dependency Plugin doc).

Thx Burhan Khalid, I overlooked your "You need to be root" quote, but found the way when you are not the root here.

At point 7 you need to use:

sudo env ORACLE_HOME=$ORACLE_HOME python setup.py install 

Or

sudo env ORACLE_HOME=/path/to/instantclient python setup.py install

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

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

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

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

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

try This Code

var check = function(evt){_x000D_
_x000D_
var data = document.getElementById('num').value;_x000D_
if((evt.charCode>= 48 && evt.charCode <= 57) || evt.charCode== 46 ||evt.charCode == 0){_x000D_
if(data.indexOf('.') > -1){_x000D_
 if(evt.charCode== 46)_x000D_
  evt.preventDefault();_x000D_
}_x000D_
}else_x000D_

Must it be an Eclipse plug-in? I use doxygen, just supply your code folder, it handles the rest.

If you are looking for ad-hoc items rather than something that you would put into SSIS. From within SSMS simply highlight the results grid, copy, then paste into excel, it isn't elegant, but works. Then you can save as native .xls rather than .csv

The same as an int:

float f = 6;

Also here's how to programmatically convert from an int to a float, and a single in C# is the same as a float:

int i = 8;
float f = Convert.ToSingle(i);

Or you can just cast an int to a float:

float f = (float)i;

With ES6 and later (ECMAScript 2015), you can get all properties like this:

let keys = Object.keys(myObject);

And if you wanna list out all values:

let values = Object.keys(myObject).map(key => myObject[key]);

A good idea could be to encapsulate everything inside groups, no matter if need to identify them or not. That way you can use them in your replacement string. For example:

var pattern = @"(-)(\d+)(-)";
var replaced = Regex.Replace(text, pattern, "$1AA$3"); 

or using a MatchEvaluator:

var replaced = Regex.Replace(text, pattern, m => m.Groups[1].Value + "AA" + m.Groups[3].Value);

Another way, slightly messy, could be using a lookbehind/lookahead:

(?<=-)(\d+)(?=-)

f = open('some_file.txt','r')
line_num = 0
search_phrase = "the dog barked"
for line in f.readlines():
    line_num += 1
    if line.find(search_phrase) >= 0:
        print line_num

EDIT 1.5 years later (after seeing it get another upvote): I'm leaving this as is; but if I was writing today would write something closer to Ash/suzanshakya's solution:

def line_num_for_phrase_in_file(phrase='the dog barked', filename='file.txt')
    with open(filename,'r') as f:
        for (i, line) in enumerate(f):
            if phrase in line:
                return i
    return -1

• Using with to open files is the pythonic idiom -- it ensures the file will be properly closed when the block using the file ends.
• Iterating through a file using for line in f is much better than for line in f.readlines(). The former is pythonic (e.g., would work if f is any generic iterable; not necessarily a file object that implements readlines), and more efficient f.readlines() creates an list with the entire file in memory and then iterates through it. * if search_phrase in line is more pythonic than if line.find(search_phrase) >= 0, as it doesn't require line to implement find, reads more easily to see what's intended, and isn't easily screwed up (e.g., if line.find(search_phrase) and if line.find(search_phrase) > 0 both will not work for all cases as find returns the index of the first match or -1).
• Its simpler/cleaner to wrap an iterated item in enumerate like for i, line in enumerate(f) than to initialize line_num = 0 before the loop and then manually increment in the loop. (Though arguably, this is more difficult to read for people unfamiliar with enumerate.)

See code like pythonista

You can use INSERT...SELECT syntax. Note that you can quote '1' directly in the SELECT part.

INSERT INTO mt_magazine_subscription ( 
      magazine_subscription_id, 
      subscription_name, 
      magazine_id, 
      status ) 
SELECT magazine_subscription_id, 
       subscription_name, 
       magazine_id, 
       '1'
FROM tbl_magazine_subscription
ORDER BY magazine_subscription_id ASC 

I was having the same problem and none if these worked for me. Here is what did work though...

app.factory('myService', function($http) {
    var data = function (value) {
            return $http.get(value);
    }

    return { data: data }
});

and then the function that uses it is...

vm.search = function(value) {

        var recieved_data = myService.data(value);

        recieved_data.then(
            function(fulfillment){
                vm.tags = fulfillment.data;
            }, function(){
                console.log("Server did not send tag data.");
        });
    };

The service isn't that necessary but I think its a good practise for extensibility. Most of what you will need for one will for any other, especially when using APIs. Anyway I hope this was helpful.

Try this:

{
    "ACCOUNT_EXIST": true,
    "MultipleContacts": false
}

This does the same, enhanced with CONTAINS:

Function SingleCellExtract(LookupValue As String, LookupRange As Range, ColumnNumber As Integer, Char As String)
Dim I As Long
Dim xRet As String
For I = 1 To LookupRange.Columns(1).Cells.Count
     If InStr(1, LookupRange.Cells(I, 1), LookupValue) > 0 Then
        If xRet = "" Then
            xRet = LookupRange.Cells(I, ColumnNumber) & Char
        Else
            xRet = xRet & "" & LookupRange.Cells(I, ColumnNumber) & Char
        End If
    End If
Next
SingleCellExtract = Left(xRet, Len(xRet) - 1)
End Function

You can also use .filter()

$('.slide-link').filter('[data-slide="0"]').addClass('active');

You can write a query as follows:

IF OBJECT_ID('ProcedureName','P') IS NOT NULL
    DROP PROC ProcedureName
GO

CREATE PROCEDURE [dbo].[ProcedureName]
...your query here....

To be more specific on the above syntax:
OBJECT_ID is a unique id number for an object within the database, this is used internally by SQL Server. Since we are passing ProcedureName followed by you object type P which tells the SQL Server that you should find the object called ProcedureName which is of type procedure i.e., P

This query will find the procedure and if it is available it will drop it and create new one.

For detailed information about OBJECT_ID and Object types please visit : SYS.Objects

If you need access to the internal states of a function, you're possibly better off using a class. You can make a class instance behave like a function by making it a callable, which is done by defining __call__:

class StatefulFunction( object ):
    def __init__( self ):
        self.public_value = 'foo'

    def __call__( self ):
        return self.public_value


>> f = StatefulFunction()
>> f()
`foo`
>> f.public_value = 'bar'
>> f()
`bar`

You need to use kill -9 59780 with 59780 replaced with found PID number (use lsof -wni tcp:3000 to see which process used 3000 port and get the process PID).

Or you can just modify your puma config change the tcp port tcp://127.0.0.1:3000 from 3000 to 9292 or other port that not been used.

Or you can start your rails app by using:

bundle exec puma -C config/puma.rb -b tcp://127.0.0.1:3001

The root cause

In Oracle you have three kinds of SQL statements (and additionally there are PL/SQL blocks):

• Statements in the Data Definiton Language (DDL). These statements modify the structure of the database. They begin usually with the verbs "ALTER" or "CREATE"
• Statements in the Data Modification Langugage (DML). There statements modify the content inside of tables, leaving the structure of each table unmodified. These statements usually begin with "INSERT", "MERGE" or "DELETE".
• Statements in what I call "query language" (there seems to be no canonical name for these). This statements start with the verb "SELECT".

Bind variables in Oracle are only allowed in some special places in DML and query statements. You are trying to use bind variables in a places where they are not allowed. Hence the error.

Solution

Build your statement without bind variables. Build the complete query string instead using string concatenation.

If you want to sanitize the input before concatenating the string, use the DBMS_ASSERT package.

Background

Bind variables can only be used when Oracle can build a query plan without knowing the value of the variable. For DDL statements, there is no query plan. Hence bind variables are not allowed.

In DML and query statements, bind variables are only allowed, when they are used inside a tuple (regarding the underlying set theory), i.e. when the value will be compared with the value in a table or when the value will be inserted in a table. They are not allowed to change the structure of the execution plan (e.g. to change the target table or to change the number of comparisons).

If you are running the MySQL other than default port:

mysqldump.exe -u username -p -P PORT_NO database > backup.sql

How about SymPy? Their solver looks like what you need. Have a look at their source code if you want to build the library yourself…

You would normally use -stringWithFormat here.

NSString *myString = [NSString stringWithFormat:@"%@%@%@", @"some text", stringVariable, @"some more text"];

sometimes require a carriage return:

os.popen("sudo -S %s"%(command), 'w').write('mypass\n')

Use the function advance(startIndex, endIndex):

var str = "45+22"
str = str.substringToIndex(advance(str.startIndex, countElements(str) - 1))

(1) add layer group and array to hold layers and reference to layers as global variables:

var search_group = new L.LayerGroup(); var clickArr = new Array();

(2) add map

(3) Add group layer to map

map.addLayer(search_group);

(4) the add to map function, with a popup that contains a link, which when clicked will have a remove option. This link will have, as its id the lat long of the point. This id will then be compared to when you click on one of your created markers and you want to delete it.

 map.on('click', function(e) {
        var clickPositionMarker = L.marker([e.latlng.lat,e.latlng.lng],{icon: idMarker});
        clickArr.push(clickPositionMarker);
        mapLat = e.latlng.lat;
        mapLon = e.latlng.lng;
        clickPositionMarker.addTo(search_group).bindPopup("<a name='removeClickM' id="+e.latlng.lat+"_"+e.latlng.lng+">Remove Me</a>")
                .openPopup();   

                /*   clickPositionMarker.on('click', function(e) {
                  markerDelAgain(); 
                }); */


});

(5) The remove function, compare the marker lat long to the id fired in the remove:

$(document).on("click","a[name='removeClickM']", function (e) {

      // Stop form from submitting normally
    e.preventDefault();

    for(i=0;i<clickArr.length;i++) {

    if(search_group.hasLayer(clickArr[i]))
    {
        if(clickArr[i]._latlng.lat+"_"+clickArr[i]._latlng.lng==$(this).attr('id'))
            {
                hideLayer(search_group,clickArr[i]);
                clickArr.splice(clickArr.indexOf(clickArr[i]), 1);
            }

    }

    }  

In my scenario this was happening because I renamed a parameter in swagger.yaml but did not reload the docs page.

Hence I was trying the API with an unexpected input parameter.
Long story short, F5 is my friend.

It happens that none of the above methods work. Key binding is proper, but tool tip simply doesn't show in any case, neither as completion help or on demand.

To fix it just go to Tools\Text Editor\C# (or all languages) and check the 'Parameter Information'. Now it should work

.show-grid [class*="span"]

It's a CSS selector that selects all elements with the class show-grid that has a child element whose class contains the name span.

This is what I do inside .sh file, let's consider install.sh

#!/bin/sh
echo Installing
cd .../Your_Project_Directory/com/cdy/ws/
jar cfe X.jar Main *.class
cd .../Your_Project_Directory/
ln -s .../Your_Project_Directory/com/cdy/ws/X.jar X
echo Testing...
java -jar X
echo You are Good to Go...Use hapily
#etc.

Creating Executable Jar file at the Class directory and creating a SymLink at anywhere you want.

Run it using,

$ sh install.sh[ENTER]
$ java -jar X[ENTER]

If that suits your needs, I would simply use

Application.ScreenUpdating = False

with the added benefit of accelerating your code, instead of slowing it down by using a second instance of Excel.

The correct way of getting computed style is waiting till page is rendered. It can be done in the following manner. Pay attention to timeout on getting auto values.

function getStyleInfo() {
    setTimeout(function() {
        const style = window.getComputedStyle(document.getElementById('__root__'));
        if (style.height == 'auto') {
            getStyleInfo();
        }
        // IF we got here we can do actual business logic staff
        console.log(style.height, style.width);
    }, 100);
};

window.onload=function() { getStyleInfo(); };

If you use just

window.onload=function() {
    var computedStyle = window.getComputedStyle(document.getElementById('__root__'));
}

you can get auto values for width and height because browsers does not render till full load is performed.

jQuery:

$(function(){
  // your code...this will run when DOM is ready
});

If you want to run your code after all page resources including images/frames/DOM have loaded, you need to use load event:

$(window).load(function(){
  // your code...
});

JavaScript:

window.onload = function(){
  // your code...
};

"bad enough not having a traditional for(;;) looper"?? What?

Are you trying to do

import string
for c in string.lowercase:
    ...do something with c...

Or perhaps you're using string.uppercase or string.letters?

Python doesn't have for(;;) because there are often better ways to do it. It also doesn't have character math because it's not necessary, either.

A better way to debug the code is, by using module clrprint

It prints a color full output only when pass parameter debug=True

from clrprint import *
clrprint('ERROR:', information,clr=['r','y'], debug=True)

I had to use the **/* syntax to exclude the files in a folder:

    "linterOptions": {
        "exclude": [
          "src/auto-generated/**/*",
          "src/app/auto-generated/**/*"
        ]
    },

It depends on the specific use case.

If your table is static and only has a short list of values (and there is just a small chance that this would change during a lifetime of DB), I would recommend this construction:

CREATE TABLE Foo 
(
    FooCode VARCHAR(16), -- short code or shortcut, but with some meaning.
    Name NVARCHAR(128), -- full name of entity, can be used as fallback in case when your localization for some language doesn't exist
    LocalizationCode AS ('Foo.' + FooCode) -- This could be a code for your localization table... 
)

Of course, when your table is not static at all, using INT as primary key is the best solution.

Okay If you want to change the gutter inside one row, but want those (first and last) inner divs to align with the grid surrounding the .no-gutter row, you could copy-paste-merge most answers into the following snippet:

.row.no-gutter [class*='col-']:first-child:not(:only-child) {
    padding-right: 0;
}
.row.no-gutter [class*='col-']:last-child:not(:only-child) {
    padding-left: 0;
}
.row.no-gutter [class*='col-']:not(:first-child):not(:last-child):not(:only-child) {
    padding-right: 0;
    padding-left: 0;
}

If you like to have a smaller gutter instead of completly none, just change the 0's to what you like... (eg: 5px to get 10px gutter).

java android

in my case

I want to change from

~/propic/........png

anything after /propic/ doesn't matter what before it

........png

finally, I found the code in Class StringUtils

this is the code

     public static String substringAfter(final String str, final String separator) {
         if (isEmpty(str)) {
             return str;
         }
         if (separator == null) {
             return "";
         }
         final int pos = str.indexOf(separator);
         if (pos == 0) {
             return str;
         }
         return str.substring(pos + separator.length());
     }

What I did was save a reference to the Menu at onCreateOptionsMenu. This is similar to nir's answer except instead of saving each individual item, I saved the entire menu.

Declare a Menu Menu toolbarMenu;.

Then in onCreateOptionsMenusave the menu to your variable

@Override
public boolean onCreateOptionsMenu(Menu menu)
{
    getMenuInflater().inflate(R.menu.main_menu, menu);
    toolbarMenu = menu;
    return true;
}

Now you can access your menu and all of its items anytime you want. toolbarMenu.getItem(0).setEnabled(false);

If you have Windows 10 you can use Bash on Ubuntu on Windows to install subversion.

d = {} is an empty object right now.

And d[a] is also an empty object.

It does not have any key values. So you should initialize the key values to this.

d[a] = {
greetings:'',
data:''
}

If you are using the less version to compile Bootstrap modify @modal-backdrop-opacity in your variables override file $modal-backdrop-opacity for scss.

You could use wait for exit or you can catch the HasExited property and update your UI to keep the user "informed" (expectation management):

System.Diagnostics.Process process = System.Diagnostics.Process.Start("cmd.exe");
while (!process.HasExited)
{
    //update UI
}
//done

Had this problem too and found out that the easiest way is to point your domain to the public folder and leave everything else the way they are.

PLEASE ENSURE TO USE THE RIGHT VERSION OF PHP. Save yourself some stress :)

A more modern solution:

Using display: flex and flex-direction: row

form {_x000D_
  display: flex; /* 2. display flex to the rescue */_x000D_
  flex-direction: row;_x000D_
}_x000D_
_x000D_
label, input {_x000D_
  display: block; /* 1. oh noes, my inputs are styled as block... */_x000D_
}

<form>_x000D_
  <label for="name">Name</label>_x000D_
  <input type="text" id="name" />_x000D_
  <label for="address">Address</label>_x000D_
  <input type="text" id="address" />_x000D_
  <button type="submit">_x000D_
    Submit_x000D_
  </button>_x000D_
</form>

I think when we use onClick we want to do something different than default. So, for all your links with onClick:

$("a[onClick]").on("click", function(e) {
  return e.preventDefault();
});

I've literally just arrived at the answer in my case. I'm creating a system that has implemented a create method, so I was getting this actual error because I was accessing the overridden version not the one from Eloquent.

Hope that help?

You haven't mentioned the Initial catalog name in the connection string. Give your database name as Initial Catalog name.

<add name ="AutoRepairSqlProvider" connectionString=
     "Data Source=.\SQLEXPRESS; Initial Catalog=MyDatabase; AttachDbFilename=|DataDirectory|\AutoRepairDatabase.mdf;
     Integrated Security=True;User Instance=True"/>

An ID is meant to identify the element uniquely. Any styles applied to it should also be unique to that element. If you have styles you want to apply to many elements, you should add a class to them all, rather than relying on ID selectors...

<div id="sections">
   <div id="s1" class="sec">...</div>
   <div id="s2" class="sec">...</div>
   ...
</div>

and

.sec {
    ...
}

Or in your specific case you could select all divisions inside your parent container, if nothing else is inside it, like so:

#sections > div {
    ...
}

You can do the following with Unnamed Columns:

1. Delete unnamed columns
2. Rename them (if you want to use them)

file.csv

,A,B,C
0,1,2,3
1,4,5,6
2,7,8,9

#read file df = pd.read_csv('file.csv')

Method 1: Delete Unnamed Columns

# delete one by one like column is 'Unnamed: 0' so use it's name
df.drop('Unnamed: 0', axis=1, inplace=True)

#delete all Unnamed Columns in a single code of line using regex
df.drop(df.filter(regex="Unnamed"),axis=1, inplace=True)

Method 2: Rename Unnamed Columns

df.rename(columns = {'Unnamed: 0':'Name'}, inplace = True)

If you want to write out with a blank header as in the input file, just choose 'Name' above to be ''.

I had a similar error. The answers here helped me figure out what to do.

index.html

 <!--The div element for the map -->
 <div id="map"></div>

<!--The link to external javascript file that has initMap() function-->
 <script src="main.js">

<!--Google api, this calls initMap() function-->
 <script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEYWY&callback=initMap">
</script>

main.js // This gives error

// The initMap function has not been executed
const initMap = () => {
const mapDisplayElement = document.getElementById('map');
  // The address is Uluru
const address = {lat: -25.344, lng: 131.036};
  // The zoom property specifies the zoom level for the map. Zoom: 0 is the lowest zoom,and displays the entire earth.
const map = new google.maps.Map(mapDisplayElement, { zoom: 4, center: address });
const marker = new google.maps.Marker({ position: address, map });
};

The answers here helped me figure out a solution. I used an immediately invoked the function (IIFE ) to work around it.

The error is as at the time of calling the google maps api the initMap() function has not executed.

main.js // This works

const mapDisplayElement = document.getElementById('map');
// The address is Uluru
// Run the initMap() function imidiately, 
(initMap = () => {
  const address = {lat: -25.344, lng: 131.036};
  // The zoom property specifies the zoom level for the map. Zoom: 0 is the lowest zoom,and displays the entire earth.
  const map = new google.maps.Map(mapDisplayElement, { zoom: 4, center: address });
  const marker = new google.maps.Marker({ position: address, map });
})();

You just need to add a jquery selector after the url.

See: http://api.jquery.com/load/

Example straight from the API:

$('#result').load('ajax/test.html #container');

So what that does is it loads the #container element from the specified url.

As pgb said, there are no "class variables," only "instance variables." The objective-c way of doing class variables is a static global variable inside the .m file of the class. The "static" ensures that the variable can not be used outside of that file (i.e. it can't be extern).

Apparently this issue caused by Android Studio on the various situation but the reason is build error When importing an existing project into android studio.

In my case, I've imported my exist project where I was supposed to install few build tools then finally build configuration was done with error. In this case, just do the following things

1. Close the current project
2. File>New>Import Project (Don't use the open recent project)
   
   Note: I'm sure this kind of error is not on source code when this happened on Import project.

With SQL 2012 and later, you could use TRY_CAST/TRY_CONVERT to try converting to a numeric type, e.g. TRY_CAST(answer AS float) IS NOT NULL -- note though that this will match scientific notation too (1+E34). (If you use decimal, then scientific notation won't match)

I had this problem when using X2Go. The problem happened in a folder that was shared between the remote computer and my local PC.

Solution: cd out of that folder and in again. That fixed it.

It can be done simply using PGPASSWORD. I am using psql 9.5.10. In your case the solution would be

PGPASSWORD=password psql -U myuser < myscript.sql

I have faced the same issue due to packaged name was "Java" after rename package name it was not throwing an error.

This answer is in three parts, see below for the official release (v3 and v4)

I couldn't even find the col-lg-push-x or pull classes in the original files for RC1 i downloaded, so check your bootstrap.css file. hopefully this is something they will sort out in RC2.

anyways, the col-push-* and pull classes did exist and this will suit your needs. Here is a demo

<div class="row">
    <div class="col-sm-5 col-push-5">
        Content B
    </div>
    <div class="col-sm-5 col-pull-5">
        Content A
    </div>
    <div class="col-sm-2">
        Content C
    </div>
</div>

EDIT: BELOW IS THE ANSWER FOR THE OFFICIAL RELEASE v3.0

Also see This blog post on the subject

• col-vp-push-x = push the column to the right by x number of columns, starting from where the column would normally render -> position: relative, on a vp or larger view-port.

• col-vp-pull-x = pull the column to the left by x number of columns, starting from where the column would normally render -> position: relative, on a vp or larger view-port.

  vp = xs, sm, md, or lg

  x = 1 thru 12

I think what messes most people up, is that you need to change the order of the columns in your HTML markup (in the example below, B comes before A), and that it only does the pushing or pulling on view-ports that are greater than or equal to what was specified. i.e. col-sm-push-5 will only push 5 columns on sm view-ports or greater. This is because Bootstrap is a "mobile first" framework, so your HTML should reflect the mobile version of your site. The Pushing and Pulling are then done on the larger screens.

• (Desktop) Larger view-ports get pushed and pulled.
• (Mobile) Smaller view-ports render in normal order.

DEMO

<div class="row">
    <div class="col-sm-5 col-sm-push-5">
        Content B
    </div>
    <div class="col-sm-5 col-sm-pull-5">
        Content A
    </div>
    <div class="col-sm-2">
        Content C
    </div>
</div>

View-port >= sm

|A|B|C|

View-port < sm

|B|
|A|
|C|

EDIT: BELOW IS THE ANSWER FOR v4.0

With v4 comes flexbox and other changes to the grid system and the push\pull classes have been removed in favor of using flexbox ordering.

• Use .order-* classes to control visual order (where * = 1 thru 12)
• This can also be grid tier specific .order-md-*
• Also .order-first (-1) and .order-last (13) avalable

<div class="row">_x000D_
  <div class="col order-2">1st yet 2nd</div>_x000D_
  <div class="col order-1">2nd yet 1st</div>_x000D_
</div>

I had this same problem and this link provided the solution for me:

http://www.holovaty.com/writing/cors-ie-cloudfront/

The short version of it is:

1. Edit S3 CORS config (my code sample didn't display properly)
   Note: This is already done in the original question
   Note: the code provided is not very secure, more info in the linked page.
2. Go to the "Behaviors" tab of your distribution and click to edit
3. Change "Forward Headers" from “None (Improves Caching)” to “Whitelist.”
4. Add “Origin” to the "Whitelist Headers" list
5. Save the changes

Your cloudfront distribution will update, which takes about 10 minutes. After that, all should be well, you can verify by checking that the CORS related error messages are gone from the browser.

You can use google gson library to convert json object.

Other librarys like Jackson are also available.

This won't convert it to a map. But you can do all things which you want.

For React Native Init approach (without expo) use:

npm start -- --reset-cache

A simple way to do so is to add the below code (for Seaborn):

for p in splot.patches:
    splot.annotate(format(p.get_height(), '.1f'), 
                   (p.get_x() + p.get_width() / 2., p.get_height()), 
                   ha = 'center', va = 'center', 
                   xytext = (0, 9), 
                   textcoords = 'offset points') 

Example :

splot = sns.barplot(df['X'], df['Y'])
# Annotate the bars in plot
for p in splot.patches:
    splot.annotate(format(p.get_height(), '.1f'), 
                   (p.get_x() + p.get_width() / 2., p.get_height()), 
                   ha = 'center', va = 'center', 
                   xytext = (0, 9), 
                   textcoords = 'offset points')    
plt.show()

I get the same error in Cygwin. I had to install the openssh package in Cygwin Setup.

(The strange thing was that all ssh-* commands were valid, (bash could execute as program) but the openssh package wasn't installed.)

Use JsonNode of fasterxml for the Generic Json Parsing. It internally creates a Map of key value for all the inputs.

Example:

private void test(@RequestBody JsonNode node)

input String :

{"a":"b","c":"d"}

Why was the problem: As someone already specified: If you start with a byte[] and it does not in fact contain text data, there is no "proper conversion". Strings are for text, byte[] is for binary data, and the only really sensible thing to do is to avoid converting between them unless you absolutely have to.

I was observing this problem when I was trying to create byte[] from a pdf file and then converting it to String and then taking the String as input and converting back to file.

So make sure your encoding and decoding logic is same as I did. I explicitly encoded the byte[] to Base64 and decoded it to create the file again.

Use-case: Due to some limitation I was trying to sent byte[] in request(POST) and the process was as follows:

PDF File >> Base64.encodeBase64(byte[]) >> String >> Send in request(POST) >> receive String >> Base64.decodeBase64(byte[]) >> create binary

Try this and this worked for me..

File file = new File("filePath");

        byte[] byteArray = new byte[(int) file.length()];

        try {
            FileInputStream fileInputStream = new FileInputStream(file);
            fileInputStream.read(byteArray);

            String byteArrayStr= new String(Base64.encodeBase64(byteArray));

            FileOutputStream fos = new FileOutputStream("newFilePath");
            fos.write(Base64.decodeBase64(byteArrayStr.getBytes()));
            fos.close();
        } 
        catch (FileNotFoundException e) {
            System.out.println("File Not Found.");
            e.printStackTrace();
        }
        catch (IOException e1) {
            System.out.println("Error Reading The File.");
            e1.printStackTrace();
        }

Since this is actually not a list of strings, the easiest way is to loop over it and convert each item into a new list of strings yourself:

List<String> strings = list.stream()
   .map(object -> Objects.toString(object, null))
   .collect(Collectors.toList());

Or when you're not on Java 8 yet:

List<String> strings = new ArrayList<>(list.size());
for (Object object : list) {
    strings.add(Objects.toString(object, null));
}

Or when you're not on Java 7 yet:

List<String> strings = new ArrayList<String>(list.size());
for (Object object : list) {
    strings.add(object != null ? object.toString() : null);
}

Note that you should be declaring against the interface (java.util.List in this case), not the implementation.

$id = intval($_GET['id']);
$sql = "SELECT * FROM student WHERE IDNO=$id";
$result = mysql_query($sql) or trigger_error(mysql_error().$sql);

always do it this way and it will tell you what is wrong

The primitive data types prefixed with "u" are unsigned versions with the same bit sizes. Effectively, this means they cannot store negative numbers, but on the other hand they can store positive numbers twice as large as their signed counterparts. The signed counterparts do not have "u" prefixed.

The limits for int (32 bit) are:

int: –2147483648 to 2147483647 
uint: 0 to 4294967295 

And for long (64 bit):

long: -9223372036854775808 to 9223372036854775807
ulong: 0 to 18446744073709551615

This works like magic, use it in the CSS file on the div you want to have on the new line:

.div_class {
    clear: left;
}

Or declare it in the html:

<div style="clear: left">
     <!-- Content... -->
</div>

I believe this should work:

login_div.Attributes.Add("style","display:none");

Here is an option. It works by using making an INDIRECT(ADDRESS(...)) from the ROW and COLUMN of the start cell, A1, down to the initial row + the number of rows held in B1.

SUM(INDIRECT(ADDRESS(ROW(A1),COLUMN(A1))):INDIRECT(ADDRESS(ROW(A1)+B1,COLUMN(A1))))

A1: is the start of data in a the "A" column

B1: is the number of rows to sum

With oracle 10.2g:

select  level, sequence.NEXTVAL
from  dual 
connect by level <= (select max(pk) from tbl);

will set the current sequence value to the max(pk) of your table (i.e. the next call to NEXTVAL will give you the right result); if you use Toad, press F5 to run the statement, not F9, which pages the output (thus stopping the increment after, usually, 500 rows). Good side: this solution is only DML, not DDL. Only SQL and no PL-SQL. Bad side : this solution prints max(pk) rows of output, i.e. is usually slower than the ALTER SEQUENCE solution.

In PowerShell v3, have a look at the Invoke-WebRequest and Invoke-RestMethod e.g.:

$msg = Read-Host -Prompt "Enter message"
$encmsg = [System.Web.HttpUtility]::UrlEncode($msg)
Invoke-WebRequest -Uri "http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$encmsg&encoding=windows-1255"

In current versions of Matplotlib, you can do axis.set_xticklabels(labels, fontsize='small').

(?! is useful in practice. Although strictly speaking, looking ahead is not regular expression as defined mathematically.

You can write an invert regular expression manually.

Here is a program to calculate the result automatically. Its result is machine generated, which is usually much more complex than hand writing one. But the result works.

Another way to do it would be to inspect the url bar in chrome to find the id of the element, have your WebDriver click that element, and then send the keys you use to copy and paste using the keys common function from selenium, and then printing it out or storing it as a variable, etc.

The most elegant way to fix this: use pipe. Here is example (my blog). So you can then simply use url | safe pipe to bypass the security.

<iframe [src]="url | safe"></iframe>

Refer to the documentation on npm for details: https://www.npmjs.com/package/safe-pipe

Look /etc/php5/cli/conf.d/ and delete corresponding *.ini files. This error happens when you remove some php packages not so cleanly.

If you do not want to install sqlplus on your server/machine then the following command-line tool can be your friend. It is a simple Java application, only Java 8 that you need in order to you can execute this tool.

The tool can be used to run any SQL from the Linux bash or Windows command line.

Example:

java -jar sql-runner-0.2.0-with-dependencies.jar \
     -j jdbc:oracle:thin:@//oracle-db:1521/ORCLPDB1.localdomain \
     -U "SYS as SYSDBA" \
     -P Oradoc_db1 \
      "select 1 from dual"

Documentation is here.

You can download the binary file from here.

When a module is loaded from a file in Python, __file__ is set to its path. You can then use that with other functions to find the directory that the file is located in.

Taking your examples one at a time:

A = os.path.join(os.path.dirname(__file__), '..')
# A is the parent directory of the directory where program resides.

B = os.path.dirname(os.path.realpath(__file__))
# B is the canonicalised (?) directory where the program resides.

C = os.path.abspath(os.path.dirname(__file__))
# C is the absolute path of the directory where the program resides.

You can see the various values returned from these here:

import os
print(__file__)
print(os.path.join(os.path.dirname(__file__), '..'))
print(os.path.dirname(os.path.realpath(__file__)))
print(os.path.abspath(os.path.dirname(__file__)))

and make sure you run it from different locations (such as ./text.py, ~/python/text.py and so forth) to see what difference that makes.

I just want to address some confusion first. __file__ is not a wildcard it is an attribute. Double underscore attributes and methods are considered to be "special" by convention and serve a special purpose.

http://docs.python.org/reference/datamodel.html shows many of the special methods and attributes, if not all of them.

In this case __file__ is an attribute of a module (a module object). In Python a .py file is a module. So import amodule will have an attribute of __file__ which means different things under difference circumstances.

Taken from the docs:

__file__ is the pathname of the file from which the module was loaded, if it was loaded from a file. The __file__ attribute is not present for C modules that are statically linked into the interpreter; for extension modules loaded dynamically from a shared library, it is the pathname of the shared library file.

In your case the module is accessing it's own __file__ attribute in the global namespace.

To see this in action try:

# file: test.py

print globals()
print __file__

And run:

python test.py

{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__file__':
 'test_print__file__.py', '__doc__': None, '__package__': None}
test_print__file__.py

Little unrelated but I will still put it here, For other practical purposes shell variables can be used as -

value=10
jq  '."key" = "'"$value"'"' file.json

You could use strftime, but struct tm doesn't have resolution for parts of seconds. I'm not sure if that's absolutely required for your purposes.

struct tm tm;
/* Set tm to the correct time */
char s[20]; /* strlen("2009-08-10 18:17:54") + 1 */
strftime(s, 20, "%F %H:%M:%S", &tm);

If you want to search as string, you can cast to text like this:

SELECT * FROM books WHERE price::TEXT LIKE '123%'

Delete Deep Netsted Folder like node_modules in Windows

1. Option 1

   Delete using rimraf NPM package

   • Open command prompt and change your directory to the folder where node_modules folder exists.

   • Run

     rimraf node_modules

   • Missing rimraf ERROR then Install

     npm install rimraf -g

   • When the installation completes, run

     rimraf node_modules

2. Option 2:

   Detele without installing anything

   • Create a folder with name test in any Drive

     robocopy /MIR c:\test D:\UserData\FolderToDelete > NUL

   • delete the folder test and FolderToDelete as both are empty

Why this is an issue in windows?

One of the deep nested folder structure is node_modules, Windows can’t delete the folder as its name is too long. To solve this, Easy solution, install a node module RimRaf

You can hide a part of JFrame that contains the swing controls which you want on another JFrame.

When the user clicks on a Jbutton the JFrame width increases and when he clicks on another same kind of Jbutton the JFrame comes to the default size.

  JFrame myFrame = new JFrame("");
  JButton button1 = new JButton("Basic");
  JButton button2 = new JButton("More options");
 // actionPerformed block code for button1 (Default size)  
 myFrame.setSize(400, 400);
//  actionPerformed block code for button2 (Increase width)
 myFrame.setSize(600, 400);

Since Join-Path can be piped a path value, you can pipe multiple Join-Path statements together:

Join-Path "C:" -ChildPath "Windows" | Join-Path -ChildPath "system32" | Join-Path -ChildPath "drivers"

It's not as terse as you would probably like it to be, but it's fully PowerShell and is relatively easy to read.

If you came here looking for an answer to this question but not exactly the way the OP meant, ie how do you get multi-line CMD to work in a single line, I have a sort of dangerous answer for you.

Trying to use this with things that actually use piping, like say findstr is quite problematic. The same goes for dealing with elses. But if you just want a multi-line conditional command to execute directly from CMD and not via a batch file, this should do work well.

Let's say you have something like this in a batch that you want to run directly in command prompt:

@echo off
for /r %%T IN (*.*) DO (
    if /i "%%~xT"==".sln" (
        echo "%%~T" is a normal SLN file, and not a .SLN.METAPROJ or .SLN.PROJ file
        echo Dumping SLN file contents
        type "%%~T"
    )
)

Now, you could use the line-continuation carat (^) and manually type it out like this, but warning, it's tedious and if you mess up you can learn the joy of typing it all out again.

Well, it won't work with just ^ thanks to escaping mechanisms inside of parentheses shrug At least not as-written. You actually would need to double up the carats like so:

@echo off ^
More? for /r %T IN (*.sln) DO (^^
More? if /i "%~xT"==".sln" (^^
More? echo "%~T" is a normal SLN file, and not a .SLN.METAPROJ or .SLN.PROJ file^^
More? echo Dumping SLN file contents^^
More? type "%~T"))

Instead, you can be a dirty sneaky scripter from the wrong side of the tracks that don't need no carats by swapping them out for a single pipe (|) per continuation of a loop/expression:

@echo off
for /r %T IN (*.sln) DO if /i "%~xT"==".sln" echo "%~T" is a normal SLN file, and not a .SLN.METAPROJ or .SLN.PROJ file | echo Dumping SLN file contents | type "%~T"

Don't use localhost in the url!

Short answer: You should to use "weak references" between collections, using ObjectId properties:

References store the relationships between data by including links or references from one document to another. Applications can resolve these references to access the related data. Broadly, these are normalized data models.

https://docs.mongodb.com/manual/core/data-modeling-introduction/#references

This will of course not check any referential integrity. You need to handle "dead links" on your side (application level).

HTML5 + spark-md5 and Q

Assuming your'e using a modern browser (that supports HTML5 File API), here's how you calculate the MD5 Hash of a large file (it will calculate the hash on variable chunks)

function calculateMD5Hash(file, bufferSize) {
  var def = Q.defer();

  var fileReader = new FileReader();
  var fileSlicer = File.prototype.slice || File.prototype.mozSlice || File.prototype.webkitSlice;
  var hashAlgorithm = new SparkMD5();
  var totalParts = Math.ceil(file.size / bufferSize);
  var currentPart = 0;
  var startTime = new Date().getTime();

  fileReader.onload = function(e) {
    currentPart += 1;

    def.notify({
      currentPart: currentPart,
      totalParts: totalParts
    });

    var buffer = e.target.result;
    hashAlgorithm.appendBinary(buffer);

    if (currentPart < totalParts) {
      processNextPart();
      return;
    }

    def.resolve({
      hashResult: hashAlgorithm.end(),
      duration: new Date().getTime() - startTime
    });
  };

  fileReader.onerror = function(e) {
    def.reject(e);
  };

  function processNextPart() {
    var start = currentPart * bufferSize;
    var end = Math.min(start + bufferSize, file.size);
    fileReader.readAsBinaryString(fileSlicer.call(file, start, end));
  }

  processNextPart();
  return def.promise;
}

function calculate() {

  var input = document.getElementById('file');
  if (!input.files.length) {
    return;
  }

  var file = input.files[0];
  var bufferSize = Math.pow(1024, 2) * 10; // 10MB

  calculateMD5Hash(file, bufferSize).then(
    function(result) {
      // Success
      console.log(result);
    },
    function(err) {
      // There was an error,
    },
    function(progress) {
      // We get notified of the progress as it is executed
      console.log(progress.currentPart, 'of', progress.totalParts, 'Total bytes:', progress.currentPart * bufferSize, 'of', progress.totalParts * bufferSize);
    });
}

To make things simple , please note that every time you do itr2.next() the pointer moves to the next element i.e. here if you notice carefully, then the output is perfectly fine according to the logic you have written .
This may help you in understanding better:

1st Iteration of While loop(pointer is before the 1st element):
Key: if ,value: 2 {itr2.next()=if; m.get(itr2.next()=it)=>2}

2nd Iteration of While loop(pointer is before the 3rd element):
Key: is ,value: 2 {itr2.next()=is; m.get(itr2.next()=to)=>2}

3rd Iteration of While loop(pointer is before the 5th element):
Key: be ,value: 1 {itr2.next()="be"; m.get(itr2.next()="up")=>"1"}

4th Iteration of While loop(pointer is before the 7th element):
Key: me ,value: 1 {itr2.next()="me"; m.get(itr2.next()="delegate")=>"1"}

Key: if ,value: 1
Key: it ,value: 2
Key: is ,value: 2
Key: to ,value: 2
Key: be ,value: 1
Key: up ,value: 1
Key: me ,value: 1
Key: delegate ,value: 1

It prints:

Key: if ,value: 2
Key: is ,value: 2
Key: be ,value: 1
Key: me ,value: 1

This approach worked for me:

@interface UIView (RemoveConstraints)

- (void)removeAllConstraints;

@end


@implementation UIView (RemoveConstraints)

- (void)removeAllConstraints
{
    UIView *superview = self.superview;
    while (superview != nil) {
        for (NSLayoutConstraint *c in superview.constraints) {
            if (c.firstItem == self || c.secondItem == self) {
                [superview removeConstraint:c];
            }
        }
        superview = superview.superview;
    }

    [self removeConstraints:self.constraints];
    self.translatesAutoresizingMaskIntoConstraints = YES;
}

@end

After it's done executing your view remains where it was because it creates autoresizing constraints. When I don't do this the view usually disappears. Additionally, it doesn't just remove constraints from superview but traversing all the way up as there may be constraints affecting it in ancestor views.

Swift 4 Version

extension UIView {
    
    public func removeAllConstraints() {
        var _superview = self.superview
        
        while let superview = _superview {
            for constraint in superview.constraints {
                
                if let first = constraint.firstItem as? UIView, first == self {
                    superview.removeConstraint(constraint)
                }
                
                if let second = constraint.secondItem as? UIView, second == self {
                    superview.removeConstraint(constraint)
                }
            }
            
            _superview = superview.superview
        }
        
        self.removeConstraints(self.constraints)
        self.translatesAutoresizingMaskIntoConstraints = true
    }
}

From my notes:

Which parses like this:

    q=latN+lonW+(label)     location of teardrop

    t=k             keyhole (satelite map)
    t=h             hybrid

    ll=lat,-lon     center of map
    spn=w.w,h.h     span of map, degrees

iwloc has something to do with the info window. hl is obviously language.

To add a use case to this that is often not discussed, I will pose a solution when submitting a Spark application via spark-submit in local mode.

According to the gitbook Mastering Apache Spark by Jacek Laskowski:

You can run Spark in local mode. In this non-distributed single-JVM deployment mode, Spark spawns all the execution components - driver, executor, backend, and master - in the same JVM. This is the only mode where a driver is used for execution.

Thus, if you are experiencing OOM errors with the heap, it suffices to adjust the driver-memory rather than the executor-memory.

Here is an example:

spark-1.6.1/bin/spark-submit
  --class "MyClass"
  --driver-memory 12g
  --master local[*] 
  target/scala-2.10/simple-project_2.10-1.0.jar 

On how to change values in appSettings section in your app.config file:

config.AppSettings.Settings.Remove(key);
config.AppSettings.Settings.Add(key, value);

does the job.

Of course better practice is Settings class but it depends on what are you after.

It's also possible by using rsync, for example:

rsync -va --delete-after src/ dst/

where:

• -v, --verbose: increase verbosity
• -a, --archive: archive mode; equals -rlptgoD (no -H,-A,-X)
• --delete-after: delete files on the receiving side be done after the transfer has completed

If you've root privileges, prefix with sudo to override potential permission issues.

Do you have to use the java 8 idioms (steams)? Perphaps a simple solution would be to move the complexity to a map alike data structure that holds numbers as key (without repeating) and the times it ocurrs as a value. You could them iterate that map an only do something with those numbers that are ocurrs > 1.

import java.lang.Math;
import java.util.Arrays;
import java.util.List;
import java.util.Map;
import java.util.HashMap;
import java.util.Iterator;

public class RemoveDuplicates
{
  public static void main(String[] args)
  {
   List<Integer> numbers = Arrays.asList(new Integer[]{1,2,1,3,4,4});
   Map<Integer,Integer> countByNumber = new HashMap<Integer,Integer>();
   for(Integer n:numbers)
   {
     Integer count = countByNumber.get(n);
     if (count != null) {
       countByNumber.put(n,count + 1);
     } else {
       countByNumber.put(n,1);
     }
   }
   System.out.println(countByNumber);
   Iterator it = countByNumber.entrySet().iterator();
    while (it.hasNext()) {
        Map.Entry pair = (Map.Entry)it.next();
        System.out.println(pair.getKey() + " = " + pair.getValue());
    }
  }
}

You can set events on a combination of key and mouse events, and onblur as well, to be sure. In that event, store the value of the input. In the next call, compare the current value with the lastly stored value. Only do your magic if it has actually changed.

To do this in a more or less clean way:

You can associate data with a DOM element (lookup api.jquery.com/jQuery.data ) So you can write a generic set of event handlers that are assigned to all elements in the form. Each event can pass the element it was triggered by to one generic function. That one function can add the old value to the data of the element. That way, you should be able to implement this as a generic piece of code that works on your whole form and every form you'll write from now on. :) And it will probably take no more than about 20 lines of code, I guess.

Generating locales

Missing locales are generated with locale-gen:

locale-gen en_US.UTF-8

Alternatively a locale file can be created manually with localedef:[1]

localedef -i en_US -f UTF-8 en_US.UTF-8

Setting Locale Settings

The locale settings can be set (to en_US.UTF-8 in the example) as follows:

export LANGUAGE=en_US.UTF-8
export LANG=en_US.UTF-8
export LC_ALL=en_US.UTF-8
locale-gen en_US.UTF-8
dpkg-reconfigure locales

The dpkg-reconfigure locales command will open a dialog under Debian for selecting the desired locale. This dialog will not appear under Ubuntu. The Configure Locales in Ubuntu article shows how to find the information regarding Ubuntu.

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

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

Angular is simply JavaScript at the core.

Use the show_source(); function of PHP. Check for more details in show_source. This is a better method I guess.

This is an old post, but for video you might want to consider using MPEG-DASH to obfuscate your files. Plus, it will provide a better streaming experience for your users without the need for a separate streaming server. More info in this post: How to disable video/audio downloading in web pages?

Not sure it stands for anything special. It's just a convention that you supply an 'all' rule, and generally it's used to list all the sub-targets needed to build the entire project, hence the name 'all'. The only thing special about it is that often times people will put it in as the first target in the makefile, which means that just typing 'make' alone will do the same thing as 'make all'.

Regex was proposed already, but not correctly:

<?php
    $number = '00000004523423400023402340240';
    $withoutLeadingZeroes = preg_replace('/^0+/', '', $number)
    echo $withoutLeadingZeroes;
?>

output is then:

4523423400023402340240

Background on Regex: the ^ signals beginning of string and the + sign signals more or none of the preceding sign. Therefore, the regex ^0+ matches all zeroes at the beginning of a string.

Just thought I'd add, if you'd like to enumerate over the index, key, and values of a dictionary, your for loop should look like this:

for index, (key, value) in enumerate(your_dict.items()):
    print(index, key, value)
