DateTime creation = File.GetCreationTime(@"C:\test.txt");
DateTime modification = File.GetLastWriteTime(@"C:\test.txt");

An expression is something, while a statement does something.
An expression is a statement as well, but it must have a return.

I didn't need to set up remote debugging in order to get this working, I used Maven.

1. Ensure you have the Maven plugin installed into Eclipse.
2. Click Run > Run Configurations > Maven Build > new launch configuration:
   • Base directory: browse to the root of your project
   • Goals: spring-boot::run.
3. Click Apply then click Run.

NB. If your IDE has problems finding your project's source code when doing line-by-line debugging, take a look at this SO answer to find out how to manually attach your source code to the debug application.

Hope this helps someone!

I have run into this issue When I recently upgraded my IntelliJ version to 2020.3. I had to disable a plugin to solve this issue. The name of the plugin is Thrift Support.

Steps to disable the plugin is following:

1. Open the Preferences of IntelliJ. You can do so by clicking on Command + , in mac.
2. Navigate to plugins.
3. Search for the Thrift Support plugin in the search window. Click on the tick box icon to deselect it.
4. Click on the Apply icon.
5. See this image for reference

For more detail please refer to this link java.lang.UnsupportedClassVersionError 2020.3 version intellij. I found this comment in the above link which has worked for me.

bin zhao commented 31 Dec 2020 08:00 @Lejia Chen @Tobias Schulmann Workflow My IDEA3.X didn't installed Erlang plugin, I disabled Thrift Support 1.4.0 and it worked. Both IDEA 3.0 and 3.1 have the same problem.

request.getContextPath()- returns root path of your application, while ../ - returns parent directory of a file.

You use request.getContextPath(), as it will always points to root of your application. If you were to move your jsp file from one directory to another, nothing needs to be changed. Now, consider the second approach. If you were to move your jsp files from one folder to another, you'd have to make changes at every location where you are referring your files.

Also, better approach of using request.getContextPath() will be to set 'request.getContextPath()' in a variable and use that variable for referring your path.

<c:set var="context" value="${pageContext.request.contextPath}" />
<script src="${context}/themes/js/jquery.js"></script>

PS- This is the one reason I can figure out. Don't know if there is any more significance to it.

Just use len(arr):

>>> import array
>>> arr = array.array('i')
>>> arr.append('2')
>>> arr.__len__()
1
>>> len(arr)
1

Make sure your routing.yml file has 'id' specified in it. In other words, it should look like:

_category:
    path: /category/{id}

The deepcopy option is the only method that works for me:

from copy import deepcopy

a = [   [ list(range(1, 3)) for i in range(3) ]   ]
b = deepcopy(a)
b[0][1]=[3]
print('Deep:')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ]   ]
b = a*1
b[0][1]=[3]
print('*1:')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ] ]
b = a[:]
b[0][1]=[3]
print('Vector copy:')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ]  ]
b = list(a)
b[0][1]=[3]
print('List copy:')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ]  ]
b = a.copy()
b[0][1]=[3]
print('.copy():')
print(a)
print(b)
print('-----------------------------')
a = [   [ list(range(1, 3)) for i in range(3) ]  ]
b = a
b[0][1]=[3]
print('Shallow:')
print(a)
print(b)
print('-----------------------------')

leads to output of:

Deep:
[[[1, 2], [1, 2], [1, 2]]]
[[[1, 2], [3], [1, 2]]]
-----------------------------
*1:
[[[1, 2], [3], [1, 2]]]

I also come here for the same problem, The solution I found is to install npm and then restart the Visual Studio Code

The *_all() functions are so simple that for a few methods I'd just write the functions. If you have lots of identical functions, you can write a generic function:

def apply_on_all(seq, method, *args, **kwargs):
    for obj in seq:
         getattr(obj, method)(*args, **kwargs)

Or create a function factory:

def create_all_applier(method, doc=None):
    def on_all(seq, *args, **kwargs):
        for obj in seq:
            getattr(obj, method)(*args, **kwargs)
    on_all.__doc__ = doc
    return on_all

start_all = create_all_applier('start', "Start all instances")
stop_all = create_all_applier('stop', "Stop all instances")
...

You could use .data():

$("#element").click(function(){
    $(this).data('clicked', true);
});

and then check it with:

if($('#element').data('clicked')) {
    alert('yes');
}

To get a better answer you need to provide more information.

Update:

Based on your comment, I understand you want something like:

$("#element").click(function(){
    var $this = $(this);
    if($this.data('clicked')) {
        func(some, other, parameters);
    }
    else {
        $this.data('clicked', true);
        func(some, parameter);
    }
});

Use \overleftarrow to create a long arrow to the left.

\overleftarrow{blahblahblah}

From what I understand, you have your data on a table and you want to create the CSV from that data. However, you have problem creating the CSV.

My thoughts would be to iterate and parse the contents of the table and generate a string from the parsed data. You can check How to convert JSON to CSV format and store in a variable for an example. You are using jQuery in your example so that would not count as an external plugin. Then, you just have to serve the resulting string using window.open and use application/octetstream as suggested.

Had same problem - it was somewhere in the ca certificate, so I used the ca bundle used for curl, and it worked. You can download the curl ca bundle here: https://curl.haxx.se/docs/caextract.html

For encryption and security issues see this helpful article:
https://www.venditan.com/labs/2014/06/26/ssl-and-php-streams-part-1-you-are-doing-it-wrongtm/432

        'limit' => intval($limit),
        'offset' => intval($offset)
        );

    // use key 'http' even if you send the request to https://...

    $context  = stream_context_create($options);
    $response = file_get_contents($url, false, $context);

Hope that helps

Assuming a is a string. The Slice notation in python has the syntax -

list[<start>:<stop>:<step>]

So, when you do a[::-1], it starts from the end towards the first taking each element. So it reverses a. This is applicable for lists/tuples as well.

Example -

>>> a = '1234'
>>> a[::-1]
'4321'

Then you convert it to int and then back to string (Though not sure why you do that) , that just gives you back the string.

when do you call timerReset()? Perhaps you get that error when trying to call it after setTimeout() has already done its thing?

wrap it in

if (window.myTimeout) { 
  clearTimeout(myTimeout);
  myTimeout = setTimeout("timerDone()", 1000 * 1440);
}

edit: Actually, upon further reflection, since you did mention jQuery (and yet don't have any actual jQuery code here... I wonder if you have this nested within some jQuery (like inside a $(document).ready(.. and this is a matter of variable scope. If so, try this:

window.message="Logged in";
window.myTimeout = setTimeout("timerDone()",1000 * 1440);
function timerDone()
{
    window.message="Logged out";   
}
function timerReset()
{


    clearTimeout(window.myTimeout);
    window.myTimeout = setTimeout("timerDone()", 1000 * 1440);
}

the first case can also be easily done as:

A=A[0]

Based on Olivier Refalo's answer

if [ $# -eq 2 ] 
then
    echo "Setting tracking for branch " $1 " -> " $2
    git branch --set-upstream $1 $2
else
    echo "-- Local --" 
    git for-each-ref --shell --format="[ %(upstream:short) != '' ] && echo -e '\t%(refname:short) <--> %(upstream:short)'" refs/heads | sh
    echo "-- Remote --" 
    REMOTES=$(git remote -v) 
    if [ "$REMOTES" != '' ]
    then
        echo $REMOTES
    fi  
fi

It shows only local with track configured.

Write it on a script called git-track on your path an you will get a git track command

A more elaborated version on https://github.com/albfan/git-showupstream

In Java, you can escape quotes with \:

String value = " \"ROM\" ";

You can also serve on the next-highest available port doing something like this in Python:

import SimpleHTTPServer
import SocketServer

Handler = SimpleHTTPServer.SimpleHTTPRequestHandler

port = 8000
while True:
    try:
        httpd = SocketServer.TCPServer(('', port), Handler)
        print 'Serving on port', port
        httpd.serve_forever()
    except SocketServer.socket.error as exc:
        if exc.args[0] != 48:
            raise
        print 'Port', port, 'already in use'
        port += 1
    else:
        break

If you need to do the same thing for other utilities, it may be more convenient as a bash script:

#!/usr/bin/env bash

MIN_PORT=${1:-1025}
MAX_PORT=${2:-65535}

(netstat -atn | awk '{printf "%s\n%s\n", $4, $4}' | grep -oE '[0-9]*$'; seq "$MIN_PORT" "$MAX_PORT") | sort -R | head -n 1

Set that up as a executable with the name get-free-port and you can do something like this:

someprogram --port=$(get-free-port)

That's not as reliable as the native Python approach because the bash script doesn't capture the port -- another process could grab the port before your process does (race condition) -- but still may be useful enough when using a utility that doesn't have a try-try-again approach of its own.

This is by far the best post for exporting to excel from SQL:

http://www.sqlteam.com/forums/topic.asp?TOPIC_ID=49926

To quote from user madhivanan,

Apart from using DTS and Export wizard, we can also use this query to export data from SQL Server2000 to Excel

Create an Excel file named testing having the headers same as that of table columns and use these queries

1 Export data to existing EXCEL file from SQL Server table

insert into OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;', 
    'SELECT * FROM [SheetName$]') select * from SQLServerTable

2 Export data from Excel to new SQL Server table

select * 
into SQLServerTable FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [Sheet1$]')

3 Export data from Excel to existing SQL Server table (edited)

Insert into SQLServerTable Select * FROM OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
    'Excel 8.0;Database=D:\testing.xls;HDR=YES', 
    'SELECT * FROM [SheetName$]')

4 If you dont want to create an EXCEL file in advance and want to export data to it, use

EXEC sp_makewebtask 
    @outputfile = 'd:\testing.xls', 
    @query = 'Select * from Database_name..SQLServerTable', 
    @colheaders =1, 
    @FixedFont=0,@lastupdated=0,@resultstitle='Testing details'

(Now you can find the file with data in tabular format)

5 To export data to new EXCEL file with heading(column names), create the following procedure

create procedure proc_generate_excel_with_columns
(
    @db_name    varchar(100),
    @table_name varchar(100),   
    @file_name  varchar(100)
)
as

--Generate column names as a recordset
declare @columns varchar(8000), @sql varchar(8000), @data_file varchar(100)
select 
    @columns=coalesce(@columns+',','')+column_name+' as '+column_name 
from 
    information_schema.columns
where 
    table_name=@table_name
select @columns=''''''+replace(replace(@columns,' as ',''''' as '),',',',''''')

--Create a dummy file to have actual data
select @data_file=substring(@file_name,1,len(@file_name)-charindex('\',reverse(@file_name)))+'\data_file.xls'

--Generate column names in the passed EXCEL file
set @sql='exec master..xp_cmdshell ''bcp " select * from (select '+@columns+') as t" queryout "'+@file_name+'" -c'''
exec(@sql)

--Generate data in the dummy file
set @sql='exec master..xp_cmdshell ''bcp "select * from '+@db_name+'..'+@table_name+'" queryout "'+@data_file+'" -c'''
exec(@sql)

--Copy dummy file to passed EXCEL file
set @sql= 'exec master..xp_cmdshell ''type '+@data_file+' >> "'+@file_name+'"'''
exec(@sql)

--Delete dummy file 
set @sql= 'exec master..xp_cmdshell ''del '+@data_file+''''
exec(@sql)

After creating the procedure, execute it by supplying database name, table name and file path:

EXEC proc_generate_excel_with_columns 'your dbname', 'your table name','your file path'

Its a whomping 29 pages but that is because others show various other ways as well as people asking questions just like this one on how to do it.

Follow that thread entirely and look at the various questions people have asked and how they are solved. I picked up quite a bit of knowledge just skimming it and have used portions of it to get expected results.

To update single cells

A member also there Peter Larson posts the following: I think one thing is missing here. It is great to be able to Export and Import to Excel files, but how about updating single cells? Or a range of cells?

This is the principle of how you do manage that

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = -99

You can also add formulas to Excel using this:

update OPENROWSET('Microsoft.Jet.OLEDB.4.0', 
'Excel 8.0;Database=c:\test.xls;hdr=no', 
'SELECT * FROM [Sheet1$b7:b7]') set f1 = '=a7+c7'

Exporting with column names using T-SQL

Member Mladen Prajdic also has a blog entry on how to do this here

References: www.sqlteam.com (btw this is an excellent blog / forum for anyone looking to get more out of SQL Server). For error referencing I used this

Errors that may occur

If you get the following error:

OLE DB provider 'Microsoft.Jet.OLEDB.4.0' cannot be used for distributed queries

Then run this:

sp_configure 'show advanced options', 1;
GO
RECONFIGURE;
GO
sp_configure 'Ad Hoc Distributed Queries', 1;
GO
RECONFIGURE;

For temporary testing during development we can disable it by opening chrome with disabled web security like this.

Open command line terminal and go to folder where chrome is installed i.e. C:\Program Files (x86)\Google\Chrome\Application

Enter this command:

chrome.exe --user-data-dir="C:/Chrome dev session" --disable-web-security

A new browser window will open with disabled web security. Use it only for testing your app.

This is coming from JPA. In a very simple way:

• persist(entity) should be used with totally new entities, to add them to DB (if entity already exists in DB there will be EntityExistsException throw).

• merge(entity) should be used, to put entity back to persistence context if the entity was detached and was changed.

Here's a complete, self-contained example. First, use the following HTML:

<canvas id="example" width="200" height="60"></canvas>
<div id="status"></div>

Then put some squares on the canvas with random background colors:

var example = document.getElementById('example');
var context = example.getContext('2d');
context.fillStyle = randomColor();
context.fillRect(0, 0, 50, 50);
context.fillStyle = randomColor();
context.fillRect(55, 0, 50, 50);
context.fillStyle = randomColor();
context.fillRect(110, 0, 50, 50);

And print each color on mouseover:

$('#example').mousemove(function(e) {
    var pos = findPos(this);
    var x = e.pageX - pos.x;
    var y = e.pageY - pos.y;
    var coord = "x=" + x + ", y=" + y;
    var c = this.getContext('2d');
    var p = c.getImageData(x, y, 1, 1).data; 
    var hex = "#" + ("000000" + rgbToHex(p[0], p[1], p[2])).slice(-6);
    $('#status').html(coord + "<br>" + hex);
});

The code above assumes the presence of jQuery and the following utility functions:

function findPos(obj) {
    var curleft = 0, curtop = 0;
    if (obj.offsetParent) {
        do {
            curleft += obj.offsetLeft;
            curtop += obj.offsetTop;
        } while (obj = obj.offsetParent);
        return { x: curleft, y: curtop };
    }
    return undefined;
}

function rgbToHex(r, g, b) {
    if (r > 255 || g > 255 || b > 255)
        throw "Invalid color component";
    return ((r << 16) | (g << 8) | b).toString(16);
}

function randomInt(max) {
  return Math.floor(Math.random() * max);
}

function randomColor() {
    return `rgb(${randomInt(256)}, ${randomInt(256)}, ${randomInt(256)})`
}

The best way to solve this problem is, go to directory laravel/bootstrap/cache and delete all files from cache.

To do this, run the following Artisan commands on your command line
1. php artisan config:clear
2. php artisan cache:clear
3. php artisan config:cache

In your panel or server, you can execute commands by adding the following to your routes:

    Route::get('/clear-cache', function() {
        $run = Artisan::call('config:clear');
        $run = Artisan::call('cache:clear');
        $run = Artisan::call('config:cache');
        return 'FINISHED';  
    });

And then call the www.yourdomain.com/clear-cache route from your browser.

For Mac OS X:

pip install --ignore-installed six

Not sure what you are trying to do, but you have two select clauses. Do this instead:

SELECT * 
FROM ( SELECT * 
       FROM orders_products 
       INNER JOIN orders ON orders_products.orders_id = orders.orders_id 
       WHERE products_id = 181) AS A
JOIN ( SELECT * 
       FROM orders_products 
       INNER JOIN orders ON orders_products.orders_id = orders.orders_id
       WHERE products_id = 180) AS B

ON A.orders_id=B.orders_id

Update:

You could probably reduce it to something like this:

SELECT o.orders_id, 
       op1.products_id, 
       op1.quantity, 
       op2.products_id, 
       op2.quantity
FROM orders o
INNER JOIN orders_products op1 on o.orders_id = op1.orders_id  
INNER JOIN orders_products op2 on o.orders_id = op2.orders_id  
WHERE op1.products_id = 180
AND op2.products_id = 181

The after_initialize callback pattern can be improved by simply doing the following

after_initialize :some_method_goes_here, :if => :new_record?

This has a non-trivial benefit if your init code needs to deal with associations, as the following code triggers a subtle n+1 if you read the initial record without including the associated.

class Account

  has_one :config
  after_initialize :init_config

  def init_config
    self.config ||= build_config
  end

end

Similar as they are, merge! and store treat existing hashes differently depending on keynames, and will therefore affect your preference. Other than that from a syntax standpoint, merge!'s key: "value" syntax closely matches up against JavaScript and Python. I've always hated comma-separating key-value pairs, personally.

hash = {}
hash.merge!(key: "value")
hash.merge!(:key => "value")
puts hash

{:key=>"value"}

hash = {}
hash.store(:key, "value")
hash.store("key", "value")
puts hash

{:key=>"value", "key"=>"value"}

To get the shovel operator << working, I would advise using Mark Thomas's answer.

another way to create a data url from blob url may be using canvas.

var canvas = document.createElement("canvas")
var context = canvas.getContext("2d")
context.drawImage(img, 0, 0) // i assume that img.src is your blob url
var dataurl = canvas.toDataURL("your prefer type", your prefer quality)

as what i saw in mdn, canvas.toDataURL is supported well by browsers. (except ie<9, always ie<9)

You could try mixing Number() and toFixed().

Have your target number converted to a nice string with X digits then convert the formated string to a number.

Number( (myVar).toFixed(2) )

See example below:

var myNumber = 5.01;_x000D_
var multiplier = 5;_x000D_
$('#actionButton').on('click', function() {_x000D_
  $('#message').text( myNumber * multiplier );_x000D_
});_x000D_
_x000D_
$('#actionButton2').on('click', function() {_x000D_
  $('#message').text( Number( (myNumber * multiplier).toFixed(2) ) );_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>_x000D_
<button id="actionButton">Weird numbers</button>_x000D_
<button id="actionButton2">Nice numbers</button>_x000D_
_x000D_
<div id="message"></div>

#Edit (add explanation :) ) say you have an array you want to update your existing firestore document field with. You can use set(yourData, {merge: true} ) passing setOptions(second param in set function) with {merge: true} is must in order to merge the changes instead of overwriting. here is what the official documentation says about it

An options object that configures the behavior of set() calls in DocumentReference, WriteBatch, and Transaction. These calls can be configured to perform granular merges instead of overwriting the target documents in their entirety by providing a SetOptions with merge: true.

you can use this

const yourNewArray = [{who: "[email protected]", when:timestamp}
{who: "[email protected]", when:timestamp}]    


collectionRef.doc(docId).set(
  {
    proprietary: "jhon",
    sharedWith: firebase.firestore.FieldValue.arrayUnion(...yourNewArray),
  },
  { merge: true },
);

hope this helps :)

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

sudo chmod +x filename.jar

Try this, I hope this works.

Since Nov 17, 2015 you have to authenticate users to make any (even such as "get some pictures who have specific hashtag") requests. See the Instagram Platform Changelog:

That particular package does not include assemblies for dotnet core, at least not at present. You may be able to build it for core yourself with a few tweaks to the project file, but I can't say for sure without diving into the source myself.

//If you don't have .Net 4.0  :)

public void SaveStreamToFile(Stream stream, string filename)
{  
   using(Stream destination = File.Create(filename))
      Write(stream, destination);
}

//Typically I implement this Write method as a Stream extension method. 
//The framework handles buffering.

public void Write(Stream from, Stream to)
{
   for(int a = from.ReadByte(); a != -1; a = from.ReadByte())
      to.WriteByte( (byte) a );
}

/*
Note, StreamReader is an IEnumerable<Char> while Stream is an IEnumbable<byte>.
The distinction is significant such as in multiple byte character encodings 
like Unicode used in .Net where Char is one or more bytes (byte[n]). Also, the
resulting translation from IEnumerable<byte> to IEnumerable<Char> can loose bytes
or insert them (for example, "\n" vs. "\r\n") depending on the StreamReader instance
CurrentEncoding.

pygame is not distributed via pip. See this link which provides windows binaries ready for installation.

1. Install python
2. Make sure you have python on your PATH
3. Download the appropriate wheel from this link
4. Install pip using this tutorial

5. Finally, use these commands to install pygame wheel with pip

   • Python 2 (usually called pip)

     • pip install file.whl

   • Python 3 (usually called pip3)

     • pip3 install file.whl

Another tutorial for installing pygame for windows can be found here. Although the instructions are for 64bit windows, it can still be applied to 32bit

You can use CURL for this purpose see the example code:

$url = "your url";    
$content = json_encode("your data to be sent");

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
        array("Content-type: application/json"));
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);

$json_response = curl_exec($curl);

$status = curl_getinfo($curl, CURLINFO_HTTP_CODE);

if ( $status != 201 ) {
    die("Error: call to URL $url failed with status $status, response $json_response, curl_error " . curl_error($curl) . ", curl_errno " . curl_errno($curl));
}


curl_close($curl);

$response = json_decode($json_response, true);

Use simplest way of doing this-

SELECT GROUP_CONCAT(Column) from table

You're correct that this is really painful to hand out to others, but if you have to, this is how you do it.

1. Just extract the .ocx file from the .cab file (it is similar to a zip)
2. Copy to the system folder (c:\windows\sysWOW64 for 64 bit systems and c:\windows\system32 for 32 bit)
3. Use regsvr32 through the command prompt to register the file (e.g. "regsvr32 c:\windows\sysWOW64\mscomct2.ocx")

In ECMAScript implementations (for instance, ActionScript or JavaScript), Array() is a constructor function and [] is part of the array literal grammar. Both are optimized and executed in completely different ways, with the literal grammar not being dogged by the overhead of calling a function.

PHP, on the other hand, has language constructs that may look like functions but aren't treated as such. Even with PHP 5.4, which supports [] as an alternative, there is no difference in overhead because, as far as the compiler/parser is concerned, they are completely synonymous.

// Before 5.4, you could only write
$array = array(
    "foo" => "bar",
    "bar" => "foo",
);

// As of PHP 5.4, the following is synonymous with the above
$array = [
    "foo" => "bar",
    "bar" => "foo",
];

If you need to support older versions of PHP, use the former syntax. There's also an argument for readability but, being a long-time JS developer, the latter seems rather natural to me. I actually made the mistake of trying to initialise arrays using [] when I was first learning PHP.

This change to the language was originally proposed and rejected due to a majority vote against by core developers with the following reason:

This patch will not be accepted because slight majority of the core developers voted against. Though if you take a accumulated mean between core developers and userland votes seems to show the opposite it would be irresponsible to submit a patch witch is not supported or maintained in the long run.

However, it appears there was a change of heart leading up to 5.4, perhaps influenced by the implementations of support for popular databases like MongoDB (which use ECMAScript syntax).

if its a dict, flask can return it directly (Version 1.0.2)

def summary():
    d = make_summary()
    return d, 200

Android needs to be compiled for every hardware plattform / every device model seperatly with the specific drivers etc. If you manage to do that you need also break the security arrangements every manufacturer implements to prevent the installation of other software - these are also different between each model / manufacturer. So it is possible at in theory, but only there :-)

Seems like there's a bug when using rotate drawable in Android M and above as per the thread here : stackoverflow.com/a/8716798/3849039

As per my opinion, creating a custom view is the best solution for this.

Below link save my time.

https://gist.github.com/mlagerberg/4aab34e6f8bc66b1eef7/revisions

you can use @UniqueConstraint on class level, for combined primary key in a table. for example:

 @Entity
 @Table(name = "PRODUCT_ATTRIBUTE", uniqueConstraints = {
       @UniqueConstraint(columnNames = {"PRODUCT_ID"}) })

public class ProductAttribute{}

The header definition is to define the encoding of the code itself, not the resulting strings at runtime.

putting a non-ascii character like ? in the python script without the utf-8 header definition will throw a warning

Or you could simply use

View.isShown()

You can do that by applying your rotate CSS to an inner element and then adjusting the height of the element to match its width since the element was rotated to fit it into the <td>.

Also make sure you change your id #rotate to a class since you have multiple.

$(document).ready(function() {_x000D_
  $('.rotate').css('height', $('.rotate').width());_x000D_
});

JavaScript

The equivalent to the above in pure JavaScript is as follows:

jsFiddle

window.addEventListener('load', function () {
    var rotates = document.getElementsByClassName('rotate');
    for (var i = 0; i < rotates.length; i++) {
        rotates[i].style.height = rotates[i].offsetWidth + 'px';
    }
});

you must install

npm install @babel/core @babel/plugin-proposal-class-properties @babel/preset-env @babel/preset-react babel-loader

and

change entry and output

const path = require('path')        
module.exports = {
  entry: path.resolve(__dirname,'src', 'app.js'),
  output: {
    path: path.resolve(__dirname, "public","dist",'javascript'),
    filename: 'bundle.js'
  },

CDATA stands for Character Data and it means that the data in between these strings includes data that could be interpreted as XML markup, but should not be.

The key differences between CDATA and comments are:

• As Richard points out, CDATA is still part of the document, while a comment is not.
• In CDATA you cannot include the string ]]> (CDEnd), while in a comment -- is invalid.
• Parameter Entity references are not recognized inside of comments.

This means given these four snippets of XML from one well-formed document:

<!ENTITY MyParamEntity "Has been expanded">

<!--
Within this comment I can use ]]>
and other reserved characters like <
&, ', and ", but %MyParamEntity; will not be expanded
(if I retrieve the text of this node it will contain
%MyParamEntity; and not "Has been expanded")
and I can't place two dashes next to each other.
-->

<![CDATA[
Within this Character Data block I can
use double dashes as much as I want (along with <, &, ', and ")
*and* %MyParamEntity; will be expanded to the text
"Has been expanded" ... however, I can't use
the CEND sequence. If I need to use CEND I must escape one of the
brackets or the greater-than sign using concatenated CDATA sections.
]]>

<description>An example of escaped CENDs</description>
<!-- This text contains a CEND ]]> -->
<!-- In this first case we put the ]] at the end of the first CDATA block
     and the > in the second CDATA block -->
<data><![CDATA[This text contains a CEND ]]]]><![CDATA[>]]></data>
<!-- In this second case we put a ] at the end of the first CDATA block
     and the ]> in the second CDATA block -->
<alternative><![CDATA[This text contains a CEND ]]]><![CDATA[]>]]></alternative>

In regards to styled-components and react-router v4 you can do this:

import {NavLink} from 'react-router-dom'

const Link = styled(NavLink)`     
  background: blue;

  &:hover {
    color: white;
  }
`

...
<Clickable><Link to="/somewhere">somewhere</Link></Clickable>

The fulfillment value of a promise parallels the return value of a function and the rejection reason of a promise parallels the thrown exception of a function. Functions cannot return multiple values so promises must not have more than 1 fulfillment value.

For a div-Element you could just set the opacity via a class to enable or disable the effect.

.mute-all {
   opacity: 0.4;
}

When you use the -m option putty does not allocate a tty, it runs the command and quits. If you want to run an interactive script (such as a sql client), you need to tell it to allocate a tty with -t, see 3.8.3.12 -t and -T: control pseudo-terminal allocation. You'll avoid keeping a script on the server, as well as having to invoke it once you're connected.

Here's what I'm using to connect to mysql from a batch file:

I think I know what you are asking for. Here is what you can do.

first get the height of the person say h meters.

if you can calculate the height of the camera from ground (using height if the person i.e. h) and get angles A and B using gyroscope or something from android then you can calculate the height of the object using the above formula.

Isn't this what you were looking for???

let me know if you need any explanation.

        title: "My Title",
        handler: { (action, view, completion) in
            //do what you want here
            completion(true)
    })

    action.image = UIImage(named: "My Image")
    action.backgroundColor = .red
    let configuration = UISwipeActionsConfiguration(actions: [action])
    configuration.performsFirstActionWithFullSwipe = false
    return configuration
}

Also, similar method is available for leadingSwipeActions

You'll have to use JS to open the popup, though you can put it on the page conditionally with PHP, you're right that you'll have to use a JavaScript function.

The only secure way of doing this

The only guaranteed secure method of retrieving the current domain is to store it in a secure location yourself.

Most frameworks take care of storing the domain for you, so you will want to consult the documentation for your particular framework. If you're not using a framework, consider storing the domain in one of the following places:

The following work... but they're not secure

Hackers can make the following variables output whatever domain they want. This can lead to cache poisoning and barely noticeable phishing attacks.

$_SERVER['HTTP_HOST']

This gets the domain from the request headers which are open to manipulation by hackers. Same with:

$_SERVER['SERVER_NAME']

This one can be made better if the Apache setting usecanonicalname is turned off; in which case $_SERVER['SERVER_NAME'] will no longer be allowed to be populated with arbitrary values and will be secure. This is, however, non-default and not as common of a setup.

In popular systems

Below is how you can get the current domain in the following frameworks/systems:

WordPress

$urlparts = parse_url(home_url());
$domain = $urlparts['host'];

If you're constructing a URL in WordPress, just use home_url or site_url, or any of the other URL functions.

Laravel

request()->getHost()

The request()->getHost function is inherited from Symfony, and has been secure since the 2013 CVE-2013-4752 was patched.

Drupal

The installer does not yet take care of making this secure (issue #2404259). But in Drupal 8 there is documentation you can you can follow at Trusted Host Settings to secure your Drupal installation after which the following can be used:

\Drupal::request()->getHost();

Other frameworks

Feel free to edit this answer to include how to get the current domain in your favorite framework. When doing so, please include a link to the relevant source code or to anything else that would help me verify that the framework is doing things securely.

Addendum

Exploitation examples:

1. Cache poisoning can happen if a botnet continuously requests a page using the wrong hosts header. The resulting HTML will then include links to the attackers website where they can phish your users. At first the malicious links will only be sent back to the hacker, but if the hacker does enough requests, the malicious version of the page will end up in your cache where it will be distributed to other users.

2. A phishing attack can happen if you store links in the database based on the hosts header. For example, let say you store the absolute URL to a user's profiles on a forum. By using the wrong header, a hacker could get anyone who clicks on their profile link to be sent a phishing site.

3. Password reset poisoning can happen if a hacker uses a malicious hosts header when filling out the password reset form for a different user. That user will then get an email containing a password reset link that leads to a phishing site. Another more complex form of this skips the user having to do anything by getting the email to bounce and resend to one of the hacker's SMTP servers (for example CVE-2017-8295.)

4. Here are some more malicious examples

Additional Caveats and Notes:

• When usecanonicalname is turned off the $_SERVER['SERVER_NAME'] is populated with the same header $_SERVER['HTTP_HOST'] would have used anyways (plus the port). This is Apache's default setup. If you or devops turns this on then you're okay -- ish -- but do you really want to rely on a separate team, or yourself three years in the future, to keep what would appear to be a minor configuration at a non-default value? Even though this makes things secure, I would caution against relying on this setup.
• Redhat, however, does turn usecanonical on by default [source].
• If serverAlias is used in the virtual hosts entry, and the aliased domain is requested, $_SERVER['SERVER_NAME'] will not return the current domain, but will return the value of the serverName directive.
• If the serverName cannot be resolved, the operating system's hostname command is used in its place [source].
• If the host header is left out, the server will behave as if usecanonical was on [source].
• Lastly, I just tried exploiting this on my local server, and was unable to spoof the hosts header. I'm not sure if there was an update to Apache that addressed this, or if I was just doing something wrong. Regardless, this header would still be exploitable in environments where virtual hosts are not being used.

Little Rant:

     This question received hundreds of thousands of views without a single mention of the security problems at hand! It shouldn't be this way, but just because a Stack Overflow answer is popular, that doesn't mean it is secure.

Fixed version of java's Integer.parseInt(text) to work with negative numbers:

public static int parseInt(String binary) {
    if (binary.length() < Integer.SIZE) return Integer.parseInt(binary, 2);

    int result = 0;
    byte[] bytes = binary.getBytes();

    for (int i = 0; i < bytes.length; i++) {
        if (bytes[i] == 49) {
            result = result | (1 << (bytes.length - 1 - i));
        }
    }

    return result;
}

The formatting shortcuts in Intellij IDEA are :

• For Windows : Ctrl + Alt + L
• For Ubuntu : Ctrl + Alt + Windows + L
• For Mac : ? (Option) + ? (Command) + L

I think something like

$("#leftDiv").mouseover(function(){$(this).css("overflow","scroll");});
$("#leftDiv").mouseout(function(){$(this).css("overflow","hidden");});

To obtain multiple outputs from a function and keep them in the desired format you can save the outputs to your hard disk (in the working directory) from within the function and then load them from outside the function:

myfun <- function(x) {
                      df1 <- ...
                      df2 <- ...
                      save(df1, file = "myfile1")
                      save(df2, file = "myfile2")
}
load("myfile1")
load("myfile2")

Reload the current page:
F5
or
CTRL + R


Reload the current page, ignoring cached content (i.e. JavaScript files, images, etc.):
SHIFT + F5
or
CTRL + F5
or
CTRL + SHIFT + R

You can change the decimal separator by changing the culture used to display the number. Beware however that this will change everything else about the number (eg. grouping separator, grouping sizes, number of decimal places). From your question, it looks like you are defaulting to a culture that uses a comma as a decimal separator.

To change just the decimal separator without changing the culture, you can modify the NumberDecimalSeparator property of the current culture's NumberFormatInfo.

Thread.CurrentCulture.NumberFormat.NumberDecimalSeparator = ".";

This will modify the current culture of the thread. All output will now be altered, meaning that you can just use value.ToString() to output the format you want, without worrying about changing the culture each time you output a number.

_{(Note that a neutral culture cannot have its decimal separator changed.)}

I found this way of using ajax which helped me as it was better in use as not having complex json syntaxes

//fifth
function GetAjaxDataPromise(url, postData) {
    debugger;
    var promise = $.post(url, postData, function (promise, status) {
    });
    return promise;
};
$(function () {
    $("#btnGet5").click(function () {
        debugger;
        var promises = GetAjaxDataPromise('@Url.Action("AjaxMethod", "Home")', { EmpId: $("#txtId").val(), EmpName: $("#txtName").val(), EmpSalary: $("#txtSalary").val() });
        promises.done(function (response) {
            debugger;
            alert("Hello: " + response.EmpName + " Your Employee Id Is: " + response.EmpId + "And Your Salary Is: " + response.EmpSalary);
        });
    });
});

This method comes with jquery promise the best part was on controller we can received data by using separate parameters or just by using a model class.

[HttpPost]
    public JsonResult AjaxMethod(PersonModel personModel)
    {
        PersonModel person = new PersonModel
        {
            EmpId = personModel.EmpId,
            EmpName = personModel.EmpName,
            EmpSalary = personModel.EmpSalary
        };
        return Json(person);
    }

or

[HttpPost]
    public JsonResult AjaxMethod(string empId, string empName, string empSalary)
    {
        PersonModel person = new PersonModel
        {
            EmpId = empId,
            EmpName = empName,
            EmpSalary = empSalary
        };
        return Json(person);
    } 

It works for both of the cases. SO you must try out this way. Got the reference from Using Ajax With Asp.Net MVC

There are few more ways of using Ajax explained there other than this one which you must try.

With angular 6 and rxjs 6 Observable.throw(), Observable.off() has been deprecated instead you need to use throwError

ex :

return this.http.get('yoururl')
  .pipe(
    map(response => response.json()),
    catchError((e: any) =>{
      //do your processing here
      return throwError(e);
    }),
  );

For me I need to set current date and time as default value this solved my issue in View add this code :

<div class="form-group">
        @Html.LabelFor(model => model.order_date, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.order_date, new { htmlAttributes = new { @class = "form-control",@Value= DateTime.Now }  })
                @Html.ValidationMessageFor(model => model.order_date, "", new { @class = "text-danger" })
                
            </div>
        </div>

Even better, try an OrderedDict (assuming you want something like a list). Closer to a list than a regular dict since the keys have an order just like list elements have an order. With a regular dict, the keys have an arbitrary order.

Note that this is available in Python 3 and 2.7. If you want to use with an earlier version of Python you can find installable modules to do that.

I also had this issue, and fixed it by setting this setting in /etc/nginx/nginx.conf

client_max_body_size 0;

0, as in unlimited.

And also, if you have a reverse proxy running with nginx, that server should also have this setting (This is what threw me off here)

select to_timestamp(cast(epoch_ms/1000 as bigint))::date

worked for me

Python working a bit differently to JavaScript for example, the value you are concatenating needs to be same type, both int or str...

So for example the code below throw an error:

print( "Alireza" + 1980)

like this:

Traceback (most recent call last):
  File "<pyshell#12>", line 1, in <module>
    print( "Alireza" + 1980)
TypeError: can only concatenate str (not "int") to str

To solve the issue, just add str to your number or value like:

print( "Alireza" + str(1980))

And the result as:

Alireza1980

request.getSession() or request.getSession(true) both will return a current session only . if current session will not exist then it will create a new session.

as per docs:

The current thread must own this object's monitor. The thread releases ownership of this monitor.

wait() method simply means it releases the lock on the object. So the object will be locked only within the synchronized block/method. If thread is outside the sync block means it's not locked, if it's not locked then what would you release on the object?

The following cites the C11 standard (final draft).

6.3.1.2: When any scalar value is converted to _Bool, the result is 0 if the value compares equal to 0; otherwise, the result is 1.

bool (mapped by stdbool.h to the internal name _Bool for C) itself is an unsigned integer type:

... The type _Bool and the unsigned integer types that correspond to the standard signed integer types are the standard unsigned integer types.

According to 6.2.5p2:

An object declared as type _Bool is large enough to store the values 0 and 1.

AFAIK these definitions are semantically identical to C++ - with the minor difference of the built-in(!) names. bool for C++ and _Bool for C.

Note that C does not use the term rvalues as C++ does. However, in C pointers are scalars, so assigning a pointer to a _Bool behaves as in C++.

Just tested and QDir::currentPath() does return the path from which I called my executable.

And a symlink does not "exist". If you are executing an exe from that path you are effectively executing it from the path the symlink points to.

Either You can use LinkedHashMap<K, V> or you can implement you own CustomMap which maintains insertion order.

You can use the Following CustomHashMap with the following features:

• Insertion order is maintained, by using LinkedHashMap internally.
• Keys with null or empty strings are not allowed.
• Once key with value is created, we are not overriding its value.

HashMap vs LinkedHashMap vs CustomHashMap

interface CustomMap<K, V> extends Map<K, V> {
    public boolean insertionRule(K key, V value);
}

@SuppressWarnings({ "rawtypes", "unchecked" })
public class CustomHashMap<K, V> implements CustomMap<K, V> {
    private Map<K, V> entryMap;
    // SET: Adds the specified element to this set if it is not already present.
    private Set<K> entrySet;

    public CustomHashMap() {
        super();
        entryMap = new LinkedHashMap<K, V>();
        entrySet = new HashSet();
    }

    @Override
    public boolean insertionRule(K key, V value) {
        // KEY as null and EMPTY String is not allowed.
        if (key == null || (key instanceof String && ((String) key).trim().equals("") ) ) {
            return false;
        }

        // If key already available then, we are not overriding its value.
        if (entrySet.contains(key)) { // Then override its value, but we are not allowing
            return false;
        } else { // Add the entry
            entrySet.add(key);
            entryMap.put(key, value);
            return true;
        }
    }
    public V put(K key, V value) {
        V oldValue = entryMap.get(key);
        insertionRule(key, value);
        return oldValue;
    }
    public void putAll(Map<? extends K, ? extends V> t) {
        for (Iterator i = t.keySet().iterator(); i.hasNext();) {
            K key = (K) i.next();
            insertionRule(key, t.get(key));
        }
    }

    public void clear() {
        entryMap.clear();
        entrySet.clear();
    }
    public boolean containsKey(Object key) {
        return entryMap.containsKey(key);
    }
    public boolean containsValue(Object value) {
        return entryMap.containsValue(value);
    }
    public Set entrySet() {
        return entryMap.entrySet();
    }
    public boolean equals(Object o) {
        return entryMap.equals(o);
    }
    public V get(Object key) {
        return entryMap.get(key);
    }
    public int hashCode() {
        return entryMap.hashCode();
    }
    public boolean isEmpty() {
        return entryMap.isEmpty();
    }
    public Set keySet() {
        return entrySet;
    }
    public V remove(Object key) {
        entrySet.remove(key);
        return entryMap.remove(key);
    }
    public int size() {
        return entryMap.size();
    }
    public Collection values() {
        return entryMap.values();
    }
}

Usage of CustomHashMap:

public static void main(String[] args) {
    System.out.println("== LinkedHashMap ==");
    Map<Object, String> map2 = new LinkedHashMap<Object, String>();
    addData(map2);

    System.out.println("== CustomHashMap ==");
    Map<Object, String> map = new CustomHashMap<Object, String>();
    addData(map);
}
public static void addData(Map<Object, String> map) {
    map.put(null, "1");
    map.put("name", "Yash");
    map.put("1", "1 - Str");
    map.put("1", "2 - Str"); // Overriding value
    map.put("", "1"); // Empty String
    map.put(" ", "1"); // Empty String
    map.put(1, "Int");
    map.put(null, "2"); // Null

    for (Map.Entry<Object, String> entry : map.entrySet()) {
        System.out.println(entry.getKey() + " = " + entry.getValue());
    }
}

O/P:

== LinkedHashMap == | == CustomHashMap ==
null = 2            | name = Yash
name = Yash         | 1 = 1 - Str
1 = 2 - Str         | 1 = Int
 = 1                |
  = 1               |
1 = Int             |

If you know the KEY's are fixed then you can use EnumMap. Get the values form Properties/XML files

EX:

enum ORACLE {
    IP, URL, USER_NAME, PASSWORD, DB_Name;
}

EnumMap<ORACLE, String> props = new EnumMap<ORACLE, String>(ORACLE.class);
props.put(ORACLE.IP, "127.0.0.1");
props.put(ORACLE.URL, "...");
props.put(ORACLE.USER_NAME, "Scott");
props.put(ORACLE.PASSWORD, "Tiget");
props.put(ORACLE.DB_Name, "MyDB");

Can be done via changing the Collation. By default it is case insensitive.

Excerpt from the link:

SELECT 1
FROM dbo.Customers
WHERE   CustID = @CustID COLLATE SQL_Latin1_General_CP1_CS_AS
    AND CustPassword = @CustPassword COLLATE SQL_Latin1_General_CP1_CS_AS

Or, change the columns to be case sensitive.

In general, this depends what your map contains. If it has null values, things can get tricky and containsKey(key) or get(key, default) should be used to detect of the element really exists. In many cases the code can become simpler you can define a default value:

def mymap = [name:"Gromit", likes:"cheese", id:1234]
def x1 = mymap.get('likes', '[nothing specified]')
println "x value: ${x}" }

Note also that containsKey() or get() are much faster than setting up a closure to check the element mymap.find{ it.key == "likes" }. Using closure only makes sense if you really do something more complex in there. You could e.g. do this:

mymap.find{ // "it" is the default parameter
  if (it.key != "likes") return false
  println "x value: ${it.value}" 
  return true // stop searching
}

Or with explicit parameters:

mymap.find{ key,value ->
  (key != "likes")  return false
  println "x value: ${value}" 
  return true // stop searching
}

Since I got here with my problem I will add this answer although it is not exactly relevant to the original question. When you are implementing an interface make sure you do not forget to add the type pointer on your member function declarations. Example:

type AnimalSounder interface {
    MakeNoise()
}

type Dog struct {
    Name string
    mean bool
    BarkStrength int
}

func (dog *Dog) MakeNoise() {
    //implementation
}

I forgot the *(dog Dog) part, I do not recommend it. Then you get into ugly trouble when calling MakeNoice on an AnimalSounder interface variable of type Dog.

Why are you specifying myFile there?

Git revert reverts the commit(s) that you specify.

git revert HEAD~2

reverts the HEAD~2 commit

git revert HEAD~2 myfile

reverts HEAD~2 AND myFile

I take myFile is a file that you want to revert? In that case use

git checkout HEAD~2 -- myFile

No -- AL is the 8 least significant bits of AX. AX is the 16 least significant bits of EAX.

Perhaps it's easiest to deal with if we start with 04030201h in eax. In this case, AX will contain 0201h, AH wil contain 02h and AL will contain 01h.

Since I'm the current world record holder for the most digits of pi, I'll add my two cents:

Unless you're actually setting a new world record, the common practice is just to verify the computed digits against the known values. So that's simple enough.

In fact, I have a webpage that lists snippets of digits for the purpose of verifying computations against them: http://www.numberworld.org/digits/Pi/

But when you get into world-record territory, there's nothing to compare against.

Historically, the standard approach for verifying that computed digits are correct is to recompute the digits using a second algorithm. So if either computation goes bad, the digits at the end won't match.

This does typically more than double the amount of time needed (since the second algorithm is usually slower). But it's the only way to verify the computed digits once you've wandered into the uncharted territory of never-before-computed digits and a new world record.

Back in the days where supercomputers were setting the records, two different AGM algorithms were commonly used:

• Gauss–Legendre algorithm
• Borwein's algorithm

These are both O(N log(N)^2) algorithms that were fairly easy to implement.

However, nowadays, things are a bit different. In the last three world records, instead of performing two computations, we performed only one computation using the fastest known formula (Chudnovsky Formula):

This algorithm is much harder to implement, but it is a lot faster than the AGM algorithms.

Then we verify the binary digits using the BBP formulas for digit extraction.

This formula allows you to compute arbitrary binary digits without computing all the digits before it. So it is used to verify the last few computed binary digits. Therefore it is much faster than a full computation.

The advantage of this is:

1. Only one expensive computation is needed.

The disadvantage is:

1. An implementation of the Bailey–Borwein–Plouffe (BBP) formula is needed.
2. An additional step is needed to verify the radix conversion from binary to decimal.

_{I've glossed over some details of why verifying the last few digits implies that all the digits are correct. But it is easy to see this since any computation error will propagate to the last digits.}

Now this last step (verifying the conversion) is actually fairly important. One of the previous world record holders actually called us out on this because, initially, I didn't give a sufficient description of how it worked.

So I've pulled this snippet from my blog:

N = # of decimal digits desired
p = 64-bit prime number

Compute A using base 10 arithmetic and B using binary arithmetic.

If A = B, then with "extremely high probability", the conversion is correct.

There is a special trick I discovered by accident.

1. Select the query you wish to format.
2. Ctrl+Shift+Q (This will open your query in the query designer)
3. Then just go OK Voila! Query designer will format your query for you. Caveat is that you can only do this for statements and not procedural code, but its better than nothing.

To validate Phone number using regular expression in java script.

In india phone is 10 digit and starting digits are 6,7,8 and 9.

  var regx = /^[6-9]\d{9}$/ ;
  if(regx.test(text))
    alert("valid");
  else
    alert("invalid");
}

Duplicate your table into a table to be archived:

SELECT * INTO ArchiveTable FROM MyTable

Delete all entries in your table:

DELETE * FROM MyTable

Lets take below object as example

let obj = { property1: 'value 1', property2: 'value 2'};

First fetch all the key in the obj

let keys = Object.keys(obj) //it will return array of keys

and then loop through it

keys.forEach(key => //your way)

just putting all together

Object.keys(obj).forEach(key=>{/*code here*/})

Here is one way to do it:

>>> n = 46
>>> (n + 9) // 10 * 10
50

If you look at the inheritance tree (in version 2.6), HTMLParser inherits from SGMLParser which inherits from ParserBase which doesn't inherits from object. I.e. HTMLParser is an old-style class.

About your checking with isinstance, I did a quick test in ipython:

In [1]: class A:
   ...:     pass
   ...: 

In [2]: isinstance(A, object)
Out[2]: True

Even if a class is old-style class, it's still an instance of object.

All I needed to do to fix this problem was to right-click the Resources.resx file in the Solution Explorer and click Run Custom Tool. This re-generates the auto-generated Resources.Designer.cs file.

If the .resx file was added to the project manually, the Custom Tool property of the file must be set to "ResXFileCodeGenerator".

The problem is due to a mismatch of namespaces, which occurs if you change the "default namespace" of the assembly in the project settings. (I changed it from (previously) "Servers" to (now) "RT.Servers".)

In the auto-generated code in Resources.Designer.cs, there is the following code:

internal static global::System.Resources.ResourceManager ResourceManager {
    get {
        if (object.ReferenceEquals(resourceMan, null)) {
            global::System.Resources.ResourceManager temp = new global::System.Resources.ResourceManager("Servers.Resources", typeof(Resources).Assembly);
            resourceMan = temp;
        }
        return resourceMan;
    }
}

The literal string "Servers.Resources" had to be changed to "RT.Servers.Resources". I did this manually, but running the custom tool would have equally well done it.

You can cut off the milliseconds using a Calendar:

java.util.Date utilDate = new java.util.Date();
Calendar cal = Calendar.getInstance();
cal.setTime(utilDate);
cal.set(Calendar.MILLISECOND, 0);
System.out.println(new java.sql.Timestamp(utilDate.getTime()));
System.out.println(new java.sql.Timestamp(cal.getTimeInMillis()));

Output:

2014-04-04 10:10:17.78
2014-04-04 10:10:17.0

The following code works fine with me:

brew install zbar
pip install pyqrcode
pip install pyzbar

For QR code image creation:

import pyqrcode
qr = pyqrcode.create("test1")
qr.png("test1.png", scale=6)

For QR code decoding:

from PIL import Image
from pyzbar.pyzbar import decode
data = decode(Image.open('test1.png'))
print(data)

that prints the result:

[Decoded(data=b'test1', type='QRCODE', rect=Rect(left=24, top=24, width=126, height=126), polygon=[Point(x=24, y=24), Point(x=24, y=150), Point(x=150, y=150), Point(x=150, y=24)])]

I just ran into this problem and decided to debug it myself since i couldn't find a solution on the internet. All i did is change the mainClassName to it's whole path(with the correct subdirectories in the project ofc)

    mainClassName = 'main.java.hello.HelloWorld'

I know it's been almost one year since the post has been made, but i think someone will find this information useful.

Happy coding.

Either use window.onload this way

<script>
    window.onload = function() {
        // ...
    }
</script>

or alternatively

<script>
    window.onload = functionName;
</script>

(yes, without the parentheses)

Or just put the script at the very bottom of page, right before </body>. At that point, all HTML DOM elements are ready to be accessed by document functions.

<body>
    ...

    <script>
        functionName();
    </script>
</body>

zeusstl is right. it works for me too.

   <select class="form-control select2" id="myselect">
                      <option disabled="disabled" selected></option>
                      <option>Male</option>
                      <option>Female</option>
                    </select>

   $.getJSON("mysite/json1.php", function(json){
        $('#myselect').empty();
        $('#myselect').append($('<option>').text("Select"));
        $.each(json, function(i, obj){

  $('#myselect').append($('<option>').text(obj.text).attr('value', obj.val));
        });
  });

You can include the ruby mathn module.

require 'mathn'

This way, you are going to be able to make the division normally.

1/2              #=> (1/2)
(1/2) ** 3       #=> (1/8)
1/3*3            #=> 1
Math.sin(1/2)    #=> 0.479425538604203

This way, you get exact division (class Rational) until you decide to apply an operation that cannot be expressed as a rational, for example Math.sin.

You probably have found this out already, but for someone stuck with this problem:

$("#tableId > tbody").html("");

In practice, using self-closing tags in HTML should work just like you'd expect. But if you are concerned about writing valid HTML5, you should understand how the use of such tags behaves within the two different two syntax forms you can use. HTML5 defines both an HTML syntax and an XHTML syntax, which are similar but not identical. Which one is used depends on the media type sent by the web server.

More than likely, your pages are being served as text/html, which follows the more lenient HTML syntax. In these cases, HTML5 allows certain start tags to have an optional / before it's terminating >. In these cases, the / is optional and ignored, so <hr> and <hr /> are identical. The HTML spec calls these "void elements", and gives a list of valid ones. Strictly speaking, the optional / is only valid within the start tags of these void elements; for example, <br /> and <hr /> are valid HTML5, but <p /> is not.

The HTML5 spec makes a clear distinction between what is correct for HTML authors and for web browser developers, with the second group being required to accept all kinds of invalid "legacy" syntax. In this case, it means that HTML5-compliant browsers will accept illegal self-closed tags, like <p />, and render them as you probably expect. But for an author, that page would not be valid HTML5. (More importantly, the DOM tree you get from using this kind of illegal syntax can be seriously screwed up; self-closed <span /> tags, for example, tend to mess things up a lot).

(In the unusual case that your server knows how to send XHTML files as an XML MIME type, the page needs to conform to the XHTML DTD and XML syntax. That means self-closing tags are required for those elements defined as such.)

 arrList.set(5,newValue);

and if u want to update it then add this line also

 youradapater.NotifyDataSetChanged();

I enjoy the classic "what's the difference between a LinkedList and an ArrayList (or between a linked list and an array/vector) and why would you choose one or the other?"

The kind of answer I hope for is one that includes discussion of:

• insertion performance
• iteration performance
• memory allocation/reallocation impact
• impact of removing elements from the beginning/middle/end
• how knowing (or not knowing) the maximum size of the list can affect the decision

If you really want to put the checkboxes inside the label, try adding an extra span tag, eg.

Contrary to Martin's answer, casting to int (or ignoring the warning) isn't always safe even if you know your array doesn't have more than 2^31-1 elements. Not when compiling for 64-bit.

For example:

NSArray *array = @[@"a", @"b", @"c"];

int i = (int) [array indexOfObject:@"d"];
// indexOfObject returned NSNotFound, which is NSIntegerMax, which is LONG_MAX in 64 bit.
// We cast this to int and got -1.
// But -1 != NSNotFound. Trouble ahead!

if (i == NSNotFound) {
    // thought we'd get here, but we don't
    NSLog(@"it's not here");
}
else {
    // this is what actually happens
    NSLog(@"it's here: %d", i);

    // **** crash horribly ****
    NSLog(@"the object is %@", array[i]);
}

Building upon your existing Student class, this is how I usually do it, especially if I need more than one comparator.

public class Student implements Comparable<Student> {

    String name;
    int age;

    public Student(String name, int age) {
       this.name = name;
       this.age = age;
    }

    @Override
    public String toString() {
        return name + ":" + age;
    }

    @Override
    public int compareTo(Student o) {
        return Comparators.NAME.compare(this, o);
    }


    public static class Comparators {

        public static Comparator<Student> NAME = new Comparator<Student>() {
            @Override
            public int compare(Student o1, Student o2) {
                return o1.name.compareTo(o2.name);
            }
        };
        public static Comparator<Student> AGE = new Comparator<Student>() {
            @Override
            public int compare(Student o1, Student o2) {
                return o1.age - o2.age;
            }
        };
        public static Comparator<Student> NAMEANDAGE = new Comparator<Student>() {
            @Override
            public int compare(Student o1, Student o2) {
                int i = o1.name.compareTo(o2.name);
                if (i == 0) {
                    i = o1.age - o2.age;
                }
                return i;
            }
        };
    }
}

Usage:

List<Student> studentList = new LinkedList<>();
Collections.sort(studentList, Student.Comparators.AGE);

EDIT

Since the release of Java 8 the inner class Comparators may be greatly simplified using lambdas. Java 8 also introduces a new method for the Comparator object thenComparing, which removes the need for doing manual checking of each comparator when nesting them. Below is the Java 8 implementation of the Student.Comparators class with these changes taken into account.

public static class Comparators {
    public static final Comparator<Student> NAME = (Student o1, Student o2) -> o1.name.compareTo(o2.name);
    public static final Comparator<Student> AGE = (Student o1, Student o2) -> Integer.compare(o1.age, o2.age);
    public static final Comparator<Student> NAMEANDAGE = (Student o1, Student o2) -> NAME.thenComparing(AGE).compare(o1, o2);
}

As Diodeus stated, IE doesn't allow anything but the default border for <select> elements. However, I know of two hacks to achieve a similar effect :

1. Use a DIV that is placed absolutely at the same position as the dropdown and set it's borders. It will appear that the dropdown has a border.

2. Use a Javascript solution, for instance, the one provided here.

It may however prove to be too much effort, so you should evaluate if you really require the border.

You can use Python as a quick way to host static content. On Windows, there are many options for running Python, I've personally used CygWin and ActivePython.

To use Python as a simple HTTP server just change your working directory to the folder with your static content and type python -m SimpleHTTPServer 8000, everything in the directory will be available at http:/localhost:8000/

Python 3

To do this with Python, 3.4.1 (and probably other versions of Python 3), use the http.server module:

python -m http.server <PORT>
# or possibly:
python3 -m http.server <PORT>

# example:
python -m http.server 8080

On Windows:

py -m http.server <PORT>

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

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

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

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

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

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

Doing so:

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

Both 'is' and 'as' are valid syntax. Output is disabled by default. Try a procedure that also enables output...

create or replace procedure temp_proc is
begin
  DBMS_OUTPUT.ENABLE(1000000);
  DBMS_OUTPUT.PUT_LINE('Test');
end;

...and call it in a PLSQL block...

begin
  temp_proc;
end;

...as SQL is non-procedural.

In my case I was getting these errors during installation of an apk on a device:

• Error during Sync: An existing connection was forcibly closed by the remote host

• Error during Sync: EOF

• Unable to open connection to: localhost/127.0.0.1:5037, due to: java.net.ConnectException: Connection refused: connect

That led to:

java.io.IOException: EOF

Error while Installing APK

Restarting a device and adb devices didn't help.

I replaced a data-cable and installed the apk.

./gradlew

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew. . means "current directory".

This will do what you want. Fixed sides with 50px-width, and the content fills the remaining area.

<div style="width:100%;">
    <div style="width: 50px; float: left;">Left Side</div>
    <div style="width: 50px; float: right;">Right Side</div>
    <div style="margin-left: 50px; margin-right: 50px;">Content Goes Here</div>
</div>

I think using enumerate on the outer loop and using the index to slice the list on the inner loop is pretty Pythonic:

for index, this in enumerate(mylist):
    for that in mylist[index+1:]:
        compare(this, that)

You must use plt.show() at the end in order to see the plot

This is what worked for me:

interface Props {
  children: JSX.Element[] | JSX.Element
}

Edit I would recommend using children: React.ReactNode instead now.

I just ran into this and it was due to a mod_authnz_ldap misconfiguration in my .htaccess file. Absolutely nothing was being logged, but I kept getting a 500 error.

If you run into this particular issue, you can change the log level of mod_authnz_ldap like so:

LogLevel warn authnz_ldap_module:debug

That will use a log level of debug for mod_authnz_ldap but warn for everything else (https://httpd.apache.org/docs/2.4/en/mod/core.html#loglevel).

1. replace your custom tag with a invalid tag name. Save it
2. restore the invalid tag name back to custom tag name. Save it. Then you will be prompted to checkout the *.designer.cs files(or silently modify the designer.cs) and produce correct variable of custom tag control.

I can't see a new-line after that last brace.

As you know: "If a source file that is not empty does not end in a new-line character, ... the behavior is undefined".

In this line:

const char* cstr2 = ss.str().c_str();

ss.str() will make a copy of the contents of the stringstream. When you call c_str() on the same line, you'll be referencing legitimate data, but after that line the string will be destroyed, leaving your char* to point to unowned memory.

The JD-eclipse plugin 0.1.3 can only decompile .class files that are visible from the classpath/Build Path.

If your class resides in a .jar, you may simply add this jar to the Build Path as another library. From the Package Explorer browse your new library and open the class in the Class File Editor.

If you want to decompile any class on the file system, it has to reside in the appropriate folder hierachy, and the root folder has to be included in the build path. Here is an example:

1. Class is foo.bar.MyClass in .../someDir/foo/bar/MyClass.class
2. In your Eclipse project, add a folder with arbitrary name aClassDir, which links to .../someDir.
3. Add that linked folder to the Build Path of the project.
4. Use the Navigator View to navigate and open the .class file in the Class File Editor. (Note: Plain .class files on the file system are hidden in the Package Explorer view.)

Note: If someDir is a subfolder of your project, you might be able to skip step 2 (link folder) and add it directly to the Build Path. But that does not work, if it is the compiler output folder of the Eclipse project.

P.S. I wish I could just double click any .class file in any project subfolder without the need to have it in the classpath...

Looks like no, though it was requested, and there’s a UDF for it.

Edit: Or there’s… this. Ugh.

I think that I also faced this problem, and the best solution I found was to look at my console and figure out the error that was being thrown. So, I read it carefully and found that the problem was that I didn't specify my repo, description, and valid name in my package.json. I added those pieces of information and everything was okay.

As rightly said in above answers, by calling flush() we force hibernate to execute the SQL commands on Database. But do understand that changes are not "committed" yet. So after doing flush and before doing commit, if you access DB directly (say from SQL prompt) and check the modified rows, you will NOT see the changes.

This is same as opening 2 SQL command sessions. And changes done in 1 session are not visible to others until committed.

In simpler words, you can understand Bootstrap as a front-end web framework that was created by Twitter for faster creation of device responsive web applications. Bootstrap can also be understood mostly as a collection of CSS classes that are defined in it which can simply be used directly. It makes use of CSS, javascript, jQuery etc. in the background to create the style, effects, and actions for Bootstrap elements.

You might know that we use CSS for styling webpage elements and create classes and assign classes to webpage elements to apply the style to them. Bootstrap here makes the designing simpler since we only have to include Bootstrap files and mention Bootstrap's predefined class names for our webpage elements and they will be styled automatically through Bootstrap. Through this, we get rid of writing our own CSS classes to style webpage elements. Most importantly Bootstrap is designed in such a way that makes your website device responsive and that is the main purpose of it. Other alternates for Bootstrap could be - Foundation, Materialize etc. frameworks.

Bootstrap makes you free from writing lots of CSS code and it also saves your time that you spend on designing the web pages.

try like this

= IIF( MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ) ) = -1, "",  FormatNumber(  MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ), "CellReading_Reading"),3)) )

I think it is confusing to think of it in terms of negative numbers. Since it is a logarithm think of the negative values the same way you think of powers of ten. 10^3 = 1000 while 10^-3 = 0.001.

With this in mind and using the formulas from S Lists's answer (and assuming our base power is 1mW in all these cases) we can build a little table:

|--------|-------------------|
| P(dBm) |        P(mW)      |
|--------|-------------------|
|    50  |  100000           |    
|    40  |   10000           |    strong transmitter
|    30  |    1000           |             ^  
|    20  |     100           |             |
|    10  |      10           |             |
|     0  |       1           |
|   -10  |       0.1         |
|   -20  |       0.01        |
|   -30  |       0.001       |
|   -40  |       0.0001      |
|   -50  |       0.00001     |             |
|   -60  |       0.000001    |             |
|   -70  |       0.0000001   |             v
|   -80  |       0.00000001  |    sensitive receiver
|   -90  |       0.000000001 |
|--------|-------------------|

When I think of it like this I find that it's easier to see that the more negative the dBm value then the farther to the right of the decimal the actual power value is.

When it comes to mobile networks, it not so much that they aren't powerful enough, rather it is that they are more sensitive. When you see receivers specs with dBm far into the negative values, then what you are seeing is more sensitive equipment.

Normally you would want your transmitter to be powerful (further in to the positives) and your receiver to be sensitive (further in to the negatives).

$("#chkBox").attr('checked', false); 

This worked for me, this will uncheck the check box. In the same way we can use

$("#chkBox").attr('checked', true); 

to check the checkbox.

JavaScript is, with a very few exceptions (XMLHttpRequest onreadystatechange handlers in some versions of Firefox) event-loop concurrent. So you needn't worry about locking in this case.

JavaScript has a concurrency model based on an "event loop". This model is quite different than the model in other languages like C or Java.

...

A JavaScript runtime contains a message queue, which is a list of messages to be processed. To each message is associated a function. When the stack is empty, a message is taken out of the queue and processed. The processing consists of calling the associated function (and thus creating an initial stack frame) The message processing ends when the stack becomes empty again.

...

Each message is processed completely before any other message is processed. This offers some nice properties when reasoning about your program, including the fact that whenever a function runs, it cannot be pre-empted and will run entirely before any other code runs (and can modify data the function manipulates). This differs from C, for instance, where if a function runs in a thread, it can be stopped at any point to run some other code in another thread.

A downside of this model is that if a message takes too long to complete, the web application is unable to process user interactions like click or scroll. The browser mitigates this with the "a script is taking too long to run" dialog. A good practice to follow is to make message processing short and if possible cut down one message into several messages.

Late to the party as since 2015, Log4J 1.x has reached EOL.

Log4J 2.x onwards the JVM option should be -Dlog4j.configurationFile=<filename>

P.S. <filename> could be a file relative to the class path without the file: as suggested in the other answers.

If you are using MS SQL Server 2008 and above you can use table-valued parameters like described here http://www.sommarskog.se/arrays-in-sql-2008.html.

1. Create a table type for each parameter type you will be using

The following command creates a table type for integers:

create type int32_id_list as table (id int not null primary key)

2. Implement helper methods

public static SqlCommand AddParameter<T>(this SqlCommand command, string name, IEnumerable<T> ids)
{
  var parameter = command.CreateParameter();      

  parameter.ParameterName = name;
  parameter.TypeName = typeof(T).Name.ToLowerInvariant() + "_id_list";
  parameter.SqlDbType = SqlDbType.Structured;
  parameter.Direction = ParameterDirection.Input;

  parameter.Value = CreateIdList(ids);

  command.Parameters.Add(parameter);
  return command;
}

private static DataTable CreateIdList<T>(IEnumerable<T> ids)
{
  var table = new DataTable();
  table.Columns.Add("id", typeof (T));

  foreach (var id in ids)
  {
    table.Rows.Add(id);
  }

  return table;
}

3. Use it like this

cmd.CommandText = "select * from TableA where Age in (select id from @age)"; 
cmd.AddParameter("@age", new [] {1,2,3,4,5});

You can simply type Q: and that should solve your problem.

Add this below code for where you likes to

example

p{
   display: block; /* Fallback for non-webkit */
   display: -webkit-box;
   max-width: 400px;
   margin: 0 auto;
   -webkit-line-clamp: 2;
   -webkit-box-orient: vertical;
   overflow: hidden;
   text-overflow: ellipsis;
 }

I know the recursive solution is not the optimal one, but just wanted to add one here:

public class LinkedListDemo {

    static class Node {
        int val;
        Node next;

        public Node(int val, Node next) {
            this.val = val;
            this.next = next;
        }

        @Override
        public String toString() {
            return "" + val;
        }
    }

    public static void main(String[] args) {
        Node n = new Node(1, new Node(2, new Node(3, new Node(20, null))));
        display(n);
        n = reverse(n);
        display(n);
    }

    static Node reverse(Node n) {
        Node tail = n;
        while (tail.next != null) {
            tail = tail.next;
        }
        reverseHelper(n);
        return (tail);
    }

    static Node reverseHelper(Node n) {
        if (n.next != null) {
            Node reverse = reverseHelper(n.next);
            reverse.next = n;
            n.next = null;
            return (n);
        }
        return (n);
    }

    static void display(Node n) {
        for (; n != null; n = n.next) {
            System.out.println(n);
        }
    }
}

How to get the last N rows of a pandas DataFrame?

If you are slicing by position, __getitem__ (i.e., slicing with[]) works well, and is the most succinct solution I've found for this problem.

pd.__version__
# '0.24.2'

df = pd.DataFrame({'A': list('aaabbbbc'), 'B': np.arange(1, 9)})
df

   A  B
0  a  1
1  a  2
2  a  3
3  b  4
4  b  5
5  b  6
6  b  7
7  c  8

df[-3:]

   A  B
5  b  6
6  b  7
7  c  8

This is the same as calling df.iloc[-3:], for instance (iloc internally delegates to __getitem__).

As an aside, if you want to find the last N rows for each group, use groupby and GroupBy.tail:

df.groupby('A').tail(2)

   A  B
1  a  2
2  a  3
5  b  6
6  b  7
7  c  8

htmlStr is string then You need to Date and Time variables to string

while (reader.Read())
                {
                    DateTime Date = reader.GetDateTime(0);
                    DateTime Time = reader.GetDateTime(1);
                    htmlStr += "<tr><td>" + Date.ToString() + "</td><td>"  + 
                    Time.ToString() + "</td></tr>";                  
                }

Angular 2 simple dropdown selected value

It may help someone as I need to only show selected value, don't need to declare something in component and etc.

If your status is coming from the database then you can show selected value this way.

<div class="form-group">
    <label for="status">Status</label>
    <select class="form-control" name="status" [(ngModel)]="category.status">
       <option [value]="1" [selected]="category.status ==1">Active</option>
       <option [value]="0" [selected]="category.status ==0">In Active</option>
    </select>
</div>

If you want to hide just the axis text keeping the grid lines:

frame1 = plt.gca()
frame1.axes.xaxis.set_ticklabels([])
frame1.axes.yaxis.set_ticklabels([])

Doing set_visible(False) or set_ticks([]) will also hide the grid lines.

This is Exactly you must type on terminal to run your project without DEBUG = TRUE and then you see all assets (static) file is loading correctly On local server .

python manage.py runserver --insecure 

--insecure : it means you can run server without security mode

You can load your External JS files in Angular and you can load them directly instead of defining in index.html file.

component.ts:

ngOnInit() {
    this.loadScripts();
}


  loadScripts() {
    const dynamicScripts = [
      //scripts to be loaded
      "assets/lib/js/hand-1.3.8.js",
      "assets/lib/js/modernizr.jr.js",
      "assets/lib/js/jquery-2.2.3.js",
      "assets/lib/js/jquery-migrate-1.4.1.js",
      "assets/js/jr.utils.js"
    ];
    for (let i = 0; i < dynamicScripts.length; i++) {
      const node = document.createElement('script');
      node.src = dynamicScripts[i];
      node.type = 'text/javascript';
      node.async = false;
      document.getElementById('scripts').appendChild(node);
    }
  }

component.html:

<div id="scripts">
</div>

You can also load styles similarly.

component.ts:

ngOnInit() {
    this.loadStyles();
}


  loadStyles() {
    const dynamicStyles = [
      //styles to be loaded
      "assets/lib/css/ui.css",
      "assets/lib/css/material-theme.css",
      "assets/lib/css/custom-style.css"
    ];
    for (let i = 0; i < dynamicStyles.length; i++) {
      const node = document.createElement('link');
      node.href = dynamicStyles[i];
      node.rel = 'stylesheet';
      document.getElementById('styles').appendChild(node);
    }
  }

component.html:

<div id="styles">

Well, Bootstrap Carousel has various parameters to control.

i.e.

Interval: Specifies the delay (in milliseconds) between each slide.

pause: Pauses the carousel from going through the next slide when the mouse pointer enters the carousel, and resumes the sliding when the mouse pointer leaves the carousel.

wrap: Specifies whether the carousel should go through all slides continuously, or stop at the last slide

For your reference:

Fore more details please click here...

Hope this will help you :)

Note: This is for the further help.. I mean how can you customise or change default behaviour once carousel is loaded.

libcurl also provides CURLOPT_COOKIELIST which extracts all known cookies. All you need is to make sure the PHP/CURL binding can use it.

To fill a list with seperate instances of a class, you can use a for loop in the declaration of the list. The * multiply will link each copy to the same instance.

instancelist = [ MyClass() for i in range(29)]

and then access the instances through the index of the list.

instancelist[5].attr1 = 'whamma'

I don't know if VB.net in VS 2008 is any different, but none of the above worked for me. Double-clicking My Project in Solution Explorer brings up the window seen below. Select Application on the left, then browse for your icon using the combobox. After you build, it should show up on your exe file.

Here is the workaround:

In eclipse.ini write the following:

-vmargs
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors= org.eclipse.ecf.provider.filetransfer.httpclient
-Dhttp.proxyHost=*myproxyhost*
-Dhttp.proxyPort=*myproxyport*
-Dhttp.proxyUser=*proxy username*
-Dhttp.proxyPassword=*proxy password*
-Dhttp.nonProxyHosts=localhost|127.0.0.1

After starting eclipse verify, that you use the Manual proxy method.

What you need is named array. I wanted to write the following code:

int[] n = new int[4];

for(int i=1;i<4;i++)
{
    n[i] = 5;
}

You can switch to manual build so can control when this is done. Just make sure that Project > Build Automatically from the main menu is unchecked.

The recommended way (as noted in codex):

$wpdb->insert( $table_name, array('column_name_1'=>'hello', 'other'=> 123), array( '%s', '%d' ) );

So, you'd better to sanitize values - ALWAYS CONSIDER THE SECURITY.

There is no such thing as importing in MS SQL. I understand what you mean. It is so simple. Whenever you get/have a something.SQL file, you should just double click and it will directly open in your MS SQL Studio.

Default style you getting in res/value/style.xml like

  <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
  </style>

And just the below like in your activity tag,

android:theme="@style/AppTheme.NoActionBar"

Another possibility

if (list.Count(customer => customer.Firstname == "John") > 0) {
 //bla
}

You can pass an object as argument to the Thread.Start and use it as a shared data storage between the current thread and the initiating thread.

You can also just directly access (with the appropriate locking of course) your data members, if you started the thread using the instance form of the ThreadStart delegate.

You can't use attributes to create shared data between threads. You can use the attribute instances attached to your class as a data storage, but I fail to see how that is better than using static or instance data members.

I have set the vm argument in WAS server as -Dfile.encoding=UTF-8 to change the servers' default character set.

Javascript is pretty good at manipulating css.

 document.body.style.cursor = *cursor-url*;
 //OR
 var elementToChange = document.getElementsByTagName("body")[0];
 elementToChange.style.cursor = "url('cursor url with protocol'), auto";

or with jquery:

$("html").css("cursor: url('cursor url with protocol'), auto");

Firefox will not work unless you specify a default cursor after the imaged one!

other cursor keywords

Also remember that IE6 only supports .cur and .ani cursors.

If cursor doesn't change: In case you are moving the element under the cursor relative to the cursor position (e.g. element dragging) you have to force a redraw on the element:

// in plain js
document.getElementById('parentOfElementToBeRedrawn').style.display = 'none';
document.getElementById('parentOfElementToBeRedrawn').style.display = 'block';
// in jquery
$('#parentOfElementToBeRedrawn').hide().show(0);

working sample:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

There are a couple of options I can think of.

1. Linked List. You can use a linked list to make a dynamically growing array like thing. But you won't be able to do array[100] without having to walk through 1-99 first. And it might not be that handy for you to use either.
2. Large array. Simply create an array with more than enough space for everything
3. Resizing array. Recreate the array once you know the size and/or create a new array every time you run out of space with some margin and copy all the data to the new array.
4. Linked List Array combination. Simply use an array with a fixed size and once you run out of space, create a new array and link to that (it would be wise to keep track of the array and the link to the next array in a struct).

It is hard to say what option would be best in your situation. Simply creating a large array is ofcourse one of the easiest solutions and shouldn't give you much problems unless it's really large.

I know that it is a very old question, but I wanted to add the good solution with some in depth explanation. You will have to execute two statements on Ubuntu like systems and then it works like a charm.

Permissions in Linux can be represented with three digits. The first digit defines the permission of the owner of the files. The second digit the permissions of a specific group of users. The third digit defines the permissions for all users who are not the owner nor member of the group.

The webserver is supposed to execute with an id that is a member of the group. The webserver should never run with the same id as the owner of the files and directories. In Ubuntu runs apache under the id www-data. That id should be a member of the group for whom the permissions are specified.

To give the directory in which you want to change the content of files the proper rights, execute the statement:

find %DIR% -type d -exec chmod 770 {} \;

.That would imply in the question of the OP that the permissions for the directory %ROOT%/database should be changed accordingly. It is therefor important not to have files within that directory that should never get changed, or removed. It is therefor best practice to create a separate directory for files whose content must be changed.

Reading permissions (4) for a directory means being able to collect all files and directories with their metadata within a directory. Write permissions (2) gives the permission to change the content of the directory. Implying adding and removing files, changing permissions etc.. Execution permission (1) means that you have the right to go into that directory. Without the latter is it impossible to go deeper into the directory. The webserver needs read, write and execute permissions when the content of a file should be changed. Therefor needs the group the digit 7.

The second statement is in the question of the OP:

find %DOCUMENT_ROOT%/database -type f -exec chmod 760 {} \;

Being able to read and write a document is required, but it is not required to execute the file. The 7 is given to the owner of the files, the 6 to the group. The webserver does not need to have the permission to execute the file in order to change its content. Those write permissions should only be given to files in that directory.

All other users should not be given any permission.

For directories that do not require to change its files are group permissions of 5 sufficient. Documentation about permissions and some examples:

https://wiki.debian.org/Permissions

https://www.linux.com/learn/tutorials/309527-understanding-linux-file-permissions

http://www.linux.org/threads/file-permissions-chmod.4094/

You have set the upstream of that branch

(see:

• "How do you make an existing git branch track a remote branch?" and
• "Git: Why do I need to do --set-upstream-to all the time?"
  )

git branch -f --track my_local_branch origin/my_remote_branch
# OR (if my_local_branch is currently checked out):
$ git branch --set-upstream-to my_local_branch origin/my_remote_branch

(git branch -f --track won't work if the branch is checked out: use the second command git branch --set-upstream-to instead, or you would get "fatal: Cannot force update the current branch.")

That means your branch is already configured with:

branch.my_local_branch.remote origin
branch.my_local_branch.merge my_remote_branch

Git already has all the necessary information.
In that case:

# if you weren't already on my_local_branch branch:
git checkout my_local_branch 
# then:
git pull

is enough.

If you hadn't establish that upstream branch relationship when it came to push your 'my_local_branch', then a simple git push -u origin my_local_branch:my_remote_branch would have been enough to push and set the upstream branch.
After that, for the subsequent pulls/pushes, git pull or git push would, again, have been enough.

Problem Cause

In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There are Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.

Solution

• I assume you have installed the pip matplotlib, there is a directory in your root called ~/.matplotlib.
• Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg

From this link you can try different diagrams.

This worked for me:

Remove-Item $folderPath -Force  -Recurse -ErrorAction SilentlyContinue

Thus the folder is removed with all files in there and it is not producing error if folder path doesn't exists.

Use files.exclude:

• Go to File -> Preferences -> Settings (or on Mac Code -> Preferences -> Settings)
• Pick the workspace settings tab

• Add this code to the settings.json file displayed on the right side:

  // Place your settings in this file to overwrite default and user settings.
  
  {
      "settings": {
          "files.exclude": {
              "**/.git": true,         // this is a default value
              "**/.DS_Store": true,    // this is a default value
  
              "**/node_modules": true, // this excludes all folders 
                                      // named "node_modules" from 
                                      // the explore tree
  
              // alternative version
              "node_modules": true    // this excludes the folder 
                                      // only from the root of
                                      // your workspace 
          }
      }
  }
  

If you chose File -> Preferences -> User Settings then you configure the exclude folders globally for your current user.

Is NDEBUG standard?

Yes it is a standard macro with the semantic "Not Debug" for C89, C99, C++98, C++2003, C++2011, C++2014 standards. There are no _DEBUG macros in the standards.

C++2003 standard send the reader at "page 326" at "17.4.2.1 Headers" to standard C.

That NDEBUG is similar as This is the same as the Standard C library.

In C89 (C programmers called this standard as standard C) in "4.2 DIAGNOSTICS" section it was said

http://port70.net/~nsz/c/c89/c89-draft.html

If NDEBUG is defined as a macro name at the point in the source file where is included, the assert macro is defined simply as

     #define assert(ignore) ((void)0)

If look at the meaning of _DEBUG macros in Visual Studio https://msdn.microsoft.com/en-us/library/b0084kay.aspx then it will be seen, that this macro is automatically defined by your ?hoice of language runtime library version.

Docotic.Pdf library can be easily used to create PDF files at runtime. The library can also modify existing PDF documents (extract text/images, append pages, fill form fields, etc.)

The WPF DataGrid has an IsReadOnly property that you can set to True to ensure that users cannot edit your DataGrid's cells.

You can also set this value for individual columns in your DataGrid as needed.

I'm new to R as well and faced the exact same problem. But then I looked at my data and noticed that it is being caused due to the fact that my csv file was using a comma separator (,) in all numeric columns (Ex: 1,233,444.56 instead of 1233444.56).

I removed the comma separator in my csv file and then reloaded into R. My data frame now recognises all columns as numbers.

I'm sure there's a way to handle this within the read.csv function itself.

Try this one.

ALTER TABLE tb_TableName
ALTER COLUMN Record_Status VARCHAR(20) NOT NULL

ALTER TABLE tb_TableName
ADD CONSTRAINT DEF_Name DEFAULT '' FOR Record_Status

li{
    margin-left:50px;
}

or replace 50px with whatever you want.

For unicode characters, it is :

preg_replace("/[^[:alnum:][:space:]]/u", '', $string);

VB Version:

Given some of the answers, to get the actual swap and RAM for a single application I came up with the following, say we want to know what 'firefox' is using

sudo smem | awk '/firefox/{swap+=$5; pss+=$7;}END{print "swap = "swap/1024" PSS = "pss/1024}'
or for libvirt;
sudo smem | awk '/libvirt/{swap+=$5; pss+=$7;}END{print "swap = "swap/1024" PSS = "pss/1024}'

this will give you the total in MB like so;

swap = 0 PSS = 2096.92
swap = 224.75 PSS = 421.455

In addition, if you run a HTML document with multiple <tbody> tags through W3C's HTML Validator, with a HTML5 DOCTYPE, it will successfully validate.

I know this question is old but I just had this issue with jquery-ui v1.12.0.

Short Answer Make sure you have a folder called Images in the same place you have jquery-ui.min.css. The images folder must contains the images found with a fresh download of the jquery-ui

Long answer

My issue is that I am using gulp to merge all of my css files into a single file. When I do that, I am changing the location of the jquery-ui.min.css. The css code for the dialog expects a folder called Images in the same directory and inside this folder it expects default icons. since gulp was not copying the images into the new destination it was not showing the x icon.

According to the specification colspan="0" should result in a table width td.

However, this is only true if your table has a width! A table may contain rows of different widths. So, the only case that the renderer knows the width of the table if you define a colgroup! Otherwise, result of colspan="0" is indeterminable...

http://www.w3.org/TR/REC-html40/struct/tables.html#adef-colspan

I cannot test it on older browsers, but this is part of specification since 4.0...

Try this:

net use * /delete /y

The /y key makes it select Yes in prompt silently

The compiler is pointing the error to you, you're comparing a structure instance and nil. They're not of the same type so it considers it as an invalid comparison and yells at you.

What you want to do here is to compare a pointer to your config instance to nil, which is a valid comparison. To do that you can either use the golang new builtin, or initialize a pointer to it:

config := new(Config) // not nil

or

config := &Config{
                  host: "myhost.com", 
                  port: 22,
                 } // not nil

or

var config *Config // nil

Then you'll be able to check if

if config == nil {
    // then
}

For now I just switched registry URL from https to http. Like this:

npm config set registry="http://registry.npmjs.org/"

You can read a CSV file with headers into a NumPy structured array with np.genfromtxt. For example:

import numpy as np

csv_fname = 'file.csv'
with open(csv_fname, 'w') as fp:
    fp.write("""\
"A","B","C","D","E","F","timestamp"
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291111964948E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291113113366E12
611.88243,9089.5601,5133.0,864.07514,1715.37476,765.22777,1.291120650486E12
""")

# Read the CSV file into a Numpy record array
r = np.genfromtxt(csv_fname, delimiter=',', names=True, case_sensitive=True)
print(repr(r))

which looks like this:

array([(611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111196e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29111311e+12),
       (611.88243, 9089.5601, 5133., 864.07514, 1715.37476, 765.22777, 1.29112065e+12)],
      dtype=[('A', '<f8'), ('B', '<f8'), ('C', '<f8'), ('D', '<f8'), ('E', '<f8'), ('F', '<f8'), ('timestamp', '<f8')])

You can access a named column like this r['E']:

array([1715.37476, 1715.37476, 1715.37476])

Note: this answer previously used np.recfromcsv to read the data into a NumPy record array. While there was nothing wrong with that method, structured arrays are generally better than record arrays for speed and compatibility.

Sadly with OOTB tools, you cannot append either the system path or user path directly/easily. If you want to stick with OOTB tools, you have to query either the SYSTEM or USER path, save that value as a variable, then appends your additions and save it using setx. The two examples below show how to retrieve either, save them, and append your additions. Don't get mess with %PATH%, it is a concatenation of USER+SYSTEM, and will cause a lot of duplication in the result. You have to split them as shown below...

Append to System PATH

for /f "usebackq tokens=2,*" %A in (`reg query "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATH`) do set SYSPATH=%B

setx PATH "%SYSPATH%;C:\path1;C:\path2" /M

Append to User PATH

for /f "usebackq tokens=2,*" %A in (`reg query HKCU\Environment /v PATH`) do set userPATH=%B

setx PATH "%userPATH%;C:\path3;C:\path4"

1. install port: https://guide.macports.org/
2. install or upgrade openssl package: sudo port install openssl or sudo port upgrade openssl
3. that's it, run openssl version to see the result.

Another way (which avoids extended switch-case statements) is to define arrays of file extensions for similar processing and use a function to check the extension result against an array (with comments):

// Define valid file extension arrays (according to your needs)
var _docExts = ["pdf", "doc", "docx", "odt"];
var _imgExts = ["jpg", "jpeg", "png", "gif", "ico"];
// Checks whether an extension is included in the array
function isExtension(ext, extnArray) {
    var result = false;
    var i;
    if (ext) {
        ext = ext.toLowerCase();
        for (i = 0; i < extnArray.length; i++) {
            if (extnArray[i].toLowerCase() === ext) {
                result = true;
                break;
            }
        }
    }
    return result;
}
// Test file name and extension
var testFileName = "example-filename.jpeg";
// Get the extension from the filename
var extn = testFileName.split('.').pop();
// boolean check if extensions are in parameter array
var isDoc = isExtension(extn, _docExts);
var isImg = isExtension(extn, _imgExts);
console.log("==> isDoc: " + isDoc + " => isImg: " + isImg);
// Process according to result: if(isDoc) { // .. etc }

i made this custom function that will convert the line to vector

#include <iostream>
#include <vector>
#include <ctime>
#include <string>

using namespace std;

int main(){

    string line;
    getline(cin, line);
    int len = line.length();
    vector<string> subArray;

    for (int j = 0, k = 0; j < len; j++) {
        if (line[j] == ' ') {
            string ch = line.substr(k, j - k);
            k = j+1;
            subArray.push_back(ch);
        }
        if (j == len - 1) {
            string ch = line.substr(k, j - k+1);
            subArray.push_back(ch);
        }
    }

    return 0;
}

You can use contains:

string[] example = { "sample1", "sample2" };
var result = (from c in example where c.Contains("2") select c);
// returns only sample2
