I have experienced the same issues as you described. It appears to be a bug on Tortoise 1.7.3. I have reverted back to 1.7.2, executed a cleanup and an update. Now my SVN/Tortoise is working fine again

It's the part of the .NET Framework that isn't contained within the Client Profile. See MSDN for more info; specifically:

The .NET Framework is made up of the .NET Framework 4 Client Profile and .NET Framework 4 Extended components that exist separately in Programs and Features.

My case is absolutely simple.

You may have this problem in case if you type in WRONG password. No create user is needed (user already existed), no other permissions. Basically make sure that the password is correct. So make double-sure the password is correct

I solved the problem by using Socket.ConnectAsync Method instead of Socket.Connect Method. After invoking the Socket.ConnectAsync(SocketAsyncEventArgs), start a timer (timer_connection), if time is up, check whether socket connection is connected (if(m_clientSocket.Connected)), if not, pop up timeout error.

private void connect(string ipAdd,string port)
    {
        try
        {
            SocketAsyncEventArgs e=new SocketAsyncEventArgs();


            m_clientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

            IPAddress ip = IPAddress.Parse(serverIp);
            int iPortNo = System.Convert.ToInt16(serverPort);
            IPEndPoint ipEnd = new IPEndPoint(ip, iPortNo);

            //m_clientSocket.
            e.RemoteEndPoint = ipEnd;
            e.UserToken = m_clientSocket;
            e.Completed+=new EventHandler<SocketAsyncEventArgs>(e_Completed);                
            m_clientSocket.ConnectAsync(e);

            if (timer_connection != null)
            {
                timer_connection.Dispose();
            }
            else
            {
                timer_connection = new Timer();
            }
            timer_connection.Interval = 2000;
            timer_connection.Tick+=new EventHandler(timer_connection_Tick);
            timer_connection.Start();
        }
        catch (SocketException se)
        {
            lb_connectStatus.Text = "Connection Failed";
            MessageBox.Show(se.Message);
        }
    }
private void e_Completed(object sender,SocketAsyncEventArgs e)
    {
        lb_connectStatus.Text = "Connection Established";
        WaitForServerData();
    }
    private void timer_connection_Tick(object sender, EventArgs e)
    {
        if (!m_clientSocket.Connected)
        {
            MessageBox.Show("Connection Timeout");
            //m_clientSocket = null;

            timer_connection.Stop();
        }
    }

In answer the question heading (found by a google search) and not the re-question To stop the line breaking when you have different heading tags e.g.

<h5 style="display:inline;"> What the... </h5><h1 style="display:inline;"> heck is going on? </h1>

Will give you:

and not

heck is going on?

Select your project in the projects window > File > Project Structure > (in the Modules section) select your project and click the minus button.

Also be sure to check out \H, which toggles HTML output on/off. Not necessarily easy to read at the console, but interesting for dumping into a file (see \o) or pasting into an editor/browser window for viewing, especially with multiple rows of relatively complex data.

I had a similar problem with wget to my own live web site returning errors after installing a new SSL certificate. I'd already checked several browsers and they didn't report any errors:

wget --no-cache -O - "https://example.com/..." ERROR: The certificate of ‘example.com’ is not trusted. ERROR: The certificate of ‘example.com’ hasn't got a known issuer.

The problem was I had installed the wrong certificate authority .pem/.crt file from the issuer. Usually they bundle the SSL certificate and CA file as a zip file, but DigiCert email you the certificate and you have to figure out the matching CA on your own. https://www.digicert.com/help/ has an SSL certificate checker which lists the SSL authority and the hopefully matching CA with a nice blue link graphic if they agree:

`SSL Cert: Issuer GeoTrust TLS DV RSA Mixed SHA256 2020 CA-1

CA: Subject GeoTrust TLS DV RSA Mixed SHA256 2020 CA-1 Valid from 16/Jul/2020 to 31/May/2023 Issuer DigiCert Global Root CA`

I have to add that bundles are used by activities to pass data to themselves in the future.

When the screen rotates, or when another activity is started, the method protected void onSaveInstanceState(Bundle outState) is invoked, and the activity is destroyed. Later, another instance of the activity is created, and public void onCreate(Bundle savedInstanceState) is called. When the first instance of activity is created, the bundle is null; and if the bundle is not null, the activity continues some business started by its predecessor.

Android automatically saves the text in text fields, but it does not save everything, and subtle bugs sometimes appear.

The most common anti-pattern, though, is assuming that onCreate() does just initialization. It is wrong, because it also must restore the state.

There is an option to disable this "re-create activity on rotation" behavior, but it will not prevent restart-related bugs, it will just make them more difficult to mention.

Note also that the only method whose call is guaranteed when the activity is going to be destroyed is onPause(). (See the activity life cycle graph in the docs.)

Yes.

  Field f = Test.class.getDeclaredField("str");
  f.setAccessible(true);//Very important, this allows the setting to work.
  String value = (String) f.get(object);

Then you use the field object to get the value on an instance of the class.

Note that get method is often confusing for people. You have the field, but you don't have an instance of the object. You have to pass that to the get method

I'm running Git version 2.6.1.windows.1 on Windows 10, so I needed a slight modification to Nevik's answer (tilde instead of caret):

git diff COMMIT~ COMMIT

Another option is to quote the caret:

git diff "COMMIT^" COMMIT

The FileHandler class, located in the core logging package, sends logging output to a disk file.

You can use plt.subplots_adjust to change the spacing between the subplots Link

subplots_adjust(left=None, bottom=None, right=None, top=None, wspace=None, hspace=None)

left  = 0.125  # the left side of the subplots of the figure
right = 0.9    # the right side of the subplots of the figure
bottom = 0.1   # the bottom of the subplots of the figure
top = 0.9      # the top of the subplots of the figure
wspace = 0.2   # the amount of width reserved for blank space between subplots
hspace = 0.2   # the amount of height reserved for white space between subplots

Java 8 introduced default methods for interfaces using which you can body to the methods. According to OOPs interfaces should act as contract between two systems/parties.

But still i found a way to achieve storing properties in the interface. I admit it is kinda ugly implementation.

   import java.util.Map;
   import java.util.WeakHashMap;

interface Rectangle
{

class Storage
{
    private static final Map<Rectangle, Integer> heightMap = new WeakHashMap<>();
    private static final Map<Rectangle, Integer> widthMap = new WeakHashMap<>();
}

default public int getHeight()
{
    return Storage.heightMap.get(this);
}

default public int getWidth()
{
    return Storage.widthMap.get(this);
}

default public void setHeight(int height)
{
    Storage.heightMap.put(this, height);
}

default public void setWidth(int width)
{
    Storage.widthMap.put(this, width);
}
}

This interface is ugly. For storing simple property it needed two hashmaps and each hashmap by default creates 16 entries by default. Additionally when real object is dereferenced JVM additionally need to remove this weak reference.

lines = f.readlines()

reads all the lines of the file f. So it makes sense that there aren't any more line to read in the file f. If you want to read the file line by line, use readline().

When do you choose functional programming over object oriented?

When you anticipate a different kind of software evolution:

• Object-oriented languages are good when you have a fixed set of operations on things, and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods, and the existing classes are left alone.

• Functional languages are good when you have a fixed set of things, and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types, and the existing functions are left alone.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method.

• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

This problem has been well known for many years; in 1998, Phil Wadler dubbed it the "expression problem". Although some researchers think that the expression problem can be addressed with such language features as mixins, a widely accepted solution has yet to hit the mainstream.

What are the typical problem definitions where functional programming is a better choice?

Functional languages excel at manipulating symbolic data in tree form. A favorite example is compilers, where source and intermediate languages change seldom (mostly the same things), but compiler writers are always adding new translations and code improvements or optimizations (new operations on things). Compilation and translation more generally are "killer apps" for functional languages.

get_curr_date () {
    # get unix time
    DATE=$(date +%s)
    echo "DATE_CURR : "$DATE
}

conv_utime_hread () {
    # convert unix time to human readable format
    DATE_HREAD=$(date -d @$DATE +%Y%m%d_%H%M%S)
    echo "DATE_HREAD          : "$DATE_HREAD
}

James Padolsey created a wonderful filter that allows regex to be used for selection.

Say you have the following div:

<div class="asdf">

Padolsey's :regex filter can select it like so:

$("div:regex(class, .*sd.*)")

Also, check the official documentation on selectors.

UPDATE: : syntax Deprecation JQuery 3.0

Since jQuery.expr[':'] used in Padolsey's implementation is already deprecated and will render a syntax error in the latest version of jQuery, here is his code adapted to jQuery 3+ syntax:

jQuery.expr.pseudos.regex = jQuery.expr.createPseudo(function (expression) {
    return function (elem) {
        var matchParams = expression.split(','),
            validLabels = /^(data|css):/,
            attr = {
                method: matchParams[0].match(validLabels) ?
                    matchParams[0].split(':')[0] : 'attr',
                property: matchParams.shift().replace(validLabels, '')
            },
            regexFlags = 'ig',
            regex = new RegExp(matchParams.join('').replace(/^\s+|\s+$/g, ''), regexFlags);
        return regex.test(jQuery(elem)[attr.method](attr.property));
    }
});

If your software uses a ProxySelector (for example for using a PAC-script instead of a static host/port) and your HTTPComponents is version 4.3 or above then you can use your ProxySelector for your HttpClient like this:

ProxySelector myProxySelector = ...;
HttpClient myHttpClient = HttpClientBuilder.create().setRoutePlanner(new SystemDefaultRoutePlanner(myProxySelector))).build();

And then do your requests as usual:

HttpGet myRequest = new HttpGet("/");
myHttpClient.execute(myRequest);

When you have three columns : first_name, last_name, mid_name:

SELECT CASE 
    WHEN mid_name IS NULL OR TRIM(mid_name) ='' THEN
        CONCAT_WS( " ", first_name, last_name ) 
    ELSE 
        CONCAT_WS( " ", first_name, mid_name, last_name ) 
    END 
FROM USER;

If you aren't allowing the column to be Null you need to provide a default to populate existing rows. e.g.

ALTER TABLE dbo.YourTbl ADD
    newcol int NOT NULL CONSTRAINT DF_YourTbl_newcol DEFAULT 0

On Enterprise Edition this is a metadata only change since 2012

For problems where it seems to be an error on a line you think is correct, you can often remove/comment the line where the error appears to be and, if the error moves to the next line, there are two possibilities.

Either both lines have a problem or the previous line has a problem which is being carried forward. The most likely case is the second option (even more so if you remove another line and it moves again).

For example, the following Python program twisty_passages.py:

xyzzy = (1 +
plugh = 7

generates the error:

  File "twisty_passages.py", line 2
    plugh = 7
          ^
SyntaxError: invalid syntax

despite the problem clearly being on line 1.

In your particular case, that is the problem. The parentheses in the line before your error line is unmatched, as per the following snippet:

# open parentheses: 1  2             3
#                   v  v             v
fi2=0.460*scipy.sqrt(1-(Tr-0.566)**2/(0.434**2)+0.494
#                               ^             ^
# close parentheses:            1             2

Depending on what you're trying to achieve, the solution may be as simple as just adding another closing parenthesis at the end, to close off the sqrt function.

I can't say for certain since I don't recognise the expression off the top of my head. Hardly surprising if (assuming PSAT is the enzyme, and the use of the typeMolecule identifier) it's to do with molecular biology - I seem to recall failing Biology consistently in my youth :-)

If none of the above is working, you are probably working on EDI trasaction where you need to validate your result against an HIPPA schema or any other complex xsd for that matter. The requirement is that, say there 8 REF segments and any of them have to appear in any order and also not all are required, means to say you may have them in following order 1st REF, 3rd REF , 2nd REF, 9th REF. Under default situation EDI receive will fail, beacause default complex type is

<xs:sequence>
  <xs:element.../>
</xs:sequence>

The situation is even complex when you are calling your element by refrence and then that element in its original spot is quite complex itself. for example:

<xs:element>
<xs:complexType>
<xs:sequence>
<element name="REF1"  ref= "REF1_Mycustomelment" minOccurs="0" maxOccurs="1">
<element name="REF2"  ref= "REF2_Mycustomelment" minOccurs="0" maxOccurs="1">
<element name="REF3"  ref= "REF3_Mycustomelment" minOccurs="0" maxOccurs="1">
</xs:sequence>
</xs:complexType>
</xs:element>

Solution:

Here simply replacing "sequence" with "all" or using "choice" with min/max combinations won't work!

First thing replace "xs:sequence" with "<xs:all>" Now,You need to make some changes where you are Referring the element from, There go to:

<xs:annotation>
  <xs:appinfo>
    <b:recordinfo structure="delimited" field.........Biztalk/2003">

***Now in the above segment add trigger point in the end like this trigger_field="REF01_...complete name.." trigger_value = "38" Do the same for other REF segments where trigger value will be different like say "18", "XX" , "YY" etc..so that your record info now looks like:b:recordinfo structure="delimited" field.........Biztalk/2003" trigger_field="REF01_...complete name.." trigger_value="38">

This will make each element unique, reason being All REF segements (above example) have same structure like REF01, REF02, REF03. And during validation the structure validation is ok but it doesn't let the values repeat because it tries to look for remaining values in first REF itself. Adding triggers will make them all unique and they will pass in any order and situational cases (like use 5 out 9 and not all 9/9).

Hope it helps you, for I spent almost 20 hrs on this.

Good Luck

In Rails, the unit folder is meant to hold tests for your models, the functional folder is meant to hold tests for your controllers, and the integration folder is meant to hold tests that involve any number of controllers interacting. Fixtures are a way of organizing test data; they reside in the fixtures folder. The test_helper.rb file holds the default configuration for your tests. u can visit this.

Ugliest interface possible, but does what you ask. Zero allocations.

http://zserge.com/jsmn.html Another zero-allocation approach.

The solutions posted above all do dynamic memory allocation, hence will be inevitably end up slower at some point, depending on the data structure - and will be dangerous to include in a heap constrained environment like an embedded system.

Benchmarks of vjson, rapidjson and sajson here : http://chadaustin.me/2013/01/json-parser-benchmarking/ if you are interested in that sort of thing.

And to answer your "writer" part of the question i doubt that you could beat an efficient

printf("{%s:%s}",name,value)

implementation with any library - assuming your printf/sprintf implementation itself is lightweight of course.

EDIT: actually let me take that back, RapidJson allows on-stack allocation only through its MemoryPoolAllocator and actually makes this a default for its GenericReader. I havent done the comparison but i would expect it to be more robust than anything else listed here. It also doesnt have any dependencies, and it doesnt throw exceptions which probably makes it ultimately suitable for embedded. Fully header based lib so, easy to include anywhere.

Simple js

if ($(document).height() <= $(window).height()) {
    $("footer").addClass("navbar-fixed-bottom");
}

Update #1

$(window).on('resize', function() {
    $('footer').toggleClass("navbar-fixed-bottom", $(document).height() <= $(window).height());
});

multipart/form-data contains boundary to separate name/value pairs. The boundary acts like a marker of each chunk of name/value pairs passed when a form gets submitted. The boundary is automatically added to a content-type of a request header.

The form with enctype="multipart/form-data" attribute will have a request header Content-Type : multipart/form-data; boundary --- WebKit193844043-h (browser generated vaue).

The payload passed looks something like this:

Content-Type: multipart/form-data; boundary=---WebKitFormBoundary7MA4YWxkTrZu0gW

    -----WebKitFormBoundary7MA4YWxkTrZu0gW
    Content-Disposition: form-data; name=”file”; filename=”captcha”
    Content-Type:

    -----WebKitFormBoundary7MA4YWxkTrZu0gW
    Content-Disposition: form-data; name=”action”

    submit
    -----WebKitFormBoundary7MA4YWxkTrZu0gW--

On the webservice side, it's consumed in @Consumes("multipart/form-data") form.

Beware, when testing your webservice using chrome postman, you need to check the form data option(radio button) and File menu from the dropdown box to send attachment. Explicit provision of content-type as multipart/form-data throws an error. Because boundary is missing as it overrides the curl request of post man to server with content-type by appending the boundary which works fine.

See RFC1341 sec7.2 The Multipart Content-Type

There are special cases where arrow functions just won't do the trick:

1. If we're changing a method of an external API, and need the object's reference.

2. If we need to use special keywords that are exclusive to the function expression: arguments, yield, bind etc. For more information: Arrow function expression limitations

Example:

I assigned this function as an event handler in the Highcharts API. It's fired by the library, so the this keyword should match a specific object.

export const handleCrosshairHover = function (proceed, e) {
  const axis = this; // axis object
  proceed.apply(axis, Array.prototype.slice.call(arguments, 1)); // method arguments
};

With an arrow function, this would match the declaration scope, and we won't have access to the API obj:

export const handleCrosshairHover = (proceed, e) => {
  const axis = this; // this = undefined
  proceed.apply(axis, Array.prototype.slice.call(arguments, 1)); // compilation error
};

S22.Imap

While there are a couple of good and well-documented IMAP libraries for .NET available, none of them are free for personal, let alone commercial use...and I was just not all that satisfied with the mostly abandoned free alternatives I found.

S22.Imap supports IMAP IDLE notifications as well as SSL and partial message fetching. I have put some effort into producing documentation and keeping it up to date, because with the projects I found, documentation was often sparse or non-existent.

Feel free to give it a try and let me know if you run into any issues!

About promise composition vs. Rxjs, as this is a frequently asked question, you can refer to a number of previously asked questions on SO, among which :

• How to do the chain sequence in rxjs
• RxJS Promise Composition (passing data)
• RxJS sequence equvalent to promise.then()?

Basically, flatMap is the equivalent of Promise.then.

For your second question, do you want to replay values already emitted, or do you want to process new values as they arrive? In the first case, check the publishReplay operator. In the second case, standard subscription is enough. However you might need to be aware of the cold. vs. hot dichotomy depending on your source (cf. Hot and Cold observables : are there 'hot' and 'cold' operators? for an illustrated explanation of the concept)

You could use sed,

sed 's/.\{4\}$//' <<< "$var"

EXample:

$ var="some string.rtf"
$ var1=$(sed 's/.\{4\}$//' <<< "$var")
$ echo $var1
some string

Google crawlers are not smart enough, they can't crawl relative URLs, that's why it's always recommended to use absolute URL's for better crawlability and indexability.

Therefore, you can not use this variation

> sitemap: /sitemap.xml

Recommended syntax is

Sitemap: https://www.yourdomain.com/sitemap.xml

Note:

• Don't forgot to capitalise the first letter in "sitemap"
• Don't forgot to put space after "Sitemap:"

What you are trying to deserialize to a Dictionary is actually a Javascript object serialized to JSON. In Javascript, you can use this object as an associative array, but really it's an object, as far as the JSON standard is concerned.

So you would have no problem deserializing what you have with a standard JSON serializer (like the .net ones, DataContractJsonSerializer and JavascriptSerializer) to an object (with members called AppName, AnotherAppName, etc), but to actually interpret this as a dictionary you'll need a serializer that goes further than the Json spec, which doesn't have anything about Dictionaries as far as I know.

One such example is the one everybody uses: JSON .net

There is an other solution if you don't want to use an external lib, which is to convert your Javascript object to a list before serializing it to JSON.

var myList = [];
$.each(myObj, function(key, value) { myList.push({Key:key, Value:value}) });

now if you serialize myList to a JSON object, you should be capable of deserializing to a List<KeyValuePair<string, ValueDescription>> with any of the aforementioned serializers. That list would then be quite obvious to convert to a dictionary.

Note: ValueDescription being this class:

public class ValueDescription
{
    public string Description { get; set; }
    public string Value { get; set; }
}

In .NET Core WebAPI (version 3.0 and above):

var requestUrl = $"{Request.Scheme}://{Request.Host.Value}/";


     

According to this code golfing solution by Gaffi, the following works:

a = Split(StrConv(s, 64), Chr(0))

You can search for column in all tables in database using:

SELECT so.name 
FROM sysobjects so
INNER JOIN syscolumns sc ON so.id = sc.id 
WHERE sc.name = 'YOUR_COLUMN_NAME'

Here's a question and answer for this: Difference between screen.availHeight and window.height()

Has pics too, so you can actually see the differences. Hope this helps.

Basically, $(window).height() give you the maximum height inside of the browser window (viewport), and$(document).height() gives you the height of the document inside of the browser. Most of the time, they will be exactly the same, even with scrollbars.

Visual Studio 2019

The only thing that worked for me: Go to Tools -> Options -> Text editor -> C# -> Intellisense

And turn off

Turns out I was too eager to try everything that's new in VS :) It was broken in only one solutions though.

1. Install jquery-ui-dist

   use npm

   npm install --save jquery-ui-dist

   or yarn

   yarn add jquery-ui-dist

2. Import it inside your app code

   import 'jquery-ui-dist/jquery-ui';

   or

   require('jquery-ui-dist/jquery-ui');

Using a regex

Using a regex, you can clean everything inside <> :

import re

def cleanhtml(raw_html):
  cleanr = re.compile('<.*?>')
  cleantext = re.sub(cleanr, '', raw_html)
  return cleantext

Some HTML texts can also contain entities that are not enclosed in brackets, such as '&nsbm'. If that is the case, then you might want to write the regex as

cleanr = re.compile('<.*?>|&([a-z0-9]+|#[0-9]{1,6}|#x[0-9a-f]{1,6});')

This link contains more details on this.

Using BeautifulSoup

You could also use BeautifulSoup additional package to find out all the raw text.

You will need to explicitly set a parser when calling BeautifulSoup I recommend "lxml" as mentioned in alternative answers (much more robust than the default one (html.parser) (i.e. available without additional install).

from bs4 import BeautifulSoup
cleantext = BeautifulSoup(raw_html, "lxml").text

But it doesn't prevent you from using external libraries, so I recommend the first solution.

EDIT: To use lxml you need to pip install lxml.

I had an issue with this with an existing box (not sure what changed), but I could connect via SSH, even though the Vagrant box failed to boot up. As it happens my SSH key had changed somehow.

From the vagrant root folder I ran vagrant ssh-config which told me where the key file was. I opened this with puttygen and then it gave me a new key.

On my Linux guest, I edited ~/.ssh/authorized_keys and dropped the new public key in there.

Everything is working again - for now!

$('#toptitle').html('New world');

or

$('#toptitle').text('New world');

1. we can call a stored procedure inside stored Procedure,Function within function ,StoredProcedure within function but we can not call function within stored procedure.
2. we can call function inside select statement.
3. We can return value from function without passing output parameter as a parameter to the stored procedure.

This is what the difference i found. Please let me know if any .

This is what worked for me. I am not sure why the syntax is different, But it was extremely frustrating trying every combination of activate, inactive, deactivated, disabled, etc. In lower case upper case in quotes out of quotes in brackets out of brackets etc. Well, here's the winning combination for me, for some reason.. different than everyone else?

import tkinter

class App(object):
    def __init__(self):
        self.tree = None
        self._setup_widgets()

    def _setup_widgets(self):
        butts = tkinter.Button(text = "add line", state="disabled")
        butts.grid()

def main():  
    root = tkinter.Tk()
    app = App()
    root.mainloop()

if __name__ == "__main__":
    main()

You can use Rout redirecting.

protected void btnNewEntry_Click(object sender, EventArgs e)
{
    Response.RedirectToRoute("CMS_1"); 
}

which requires to define your routing logic in Global.asax file that could be like that:

routes.MapPageRoute("CMS_1", "CMS_1", "~/CMS_1.aspx");

where any request by CMS_1 pattern in application scope will be redirecting to CMS_1.aspx, but in URL shows like www.yoursite.com/CMS_1

You could use the System.Web.UI.WebControls.CheckBoxList control or use the System.Web.UI.WebControls.ListBox control with the SelectionMode property set to Multiple.

Public Class Form1

   Public Shared SomeValue As Integer = 5

End Class

The answer:

MessageBox.Show("this is the number"&GlobalVariables.SomeValue)

without using the System.arraycopy method you can delete an element from an array with the following

    int i = 0;
    int x = 0;
    while(i < oldArray.length){
        if(oldArray[i] == 3)i++;

        intArray[x] = oldArray[i];
        i++;
        x++;
    }

where 3 is the value you want to remove.

Even simpler, use path/filepath:

package main    

import (
    "fmt"
    "log"
    "path/filepath"
)

func main() {
    files, err := filepath.Glob("*")
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(files) // contains a list of all files in the current directory
}

If you want to due this in component.ts

HTML:

<button class="class1 class2" (click)="clicked($event)">Click me</button>

Component:

clicked(event) {
  event.target.classList.add('class3'); // To ADD
  event.target.classList.remove('class1'); // To Remove
  event.target.classList.contains('class2'); // To check
  event.target.classList.toggle('class4'); // To toggle
}

I'm not sure about best-practise, but I'd use switch - and then trap intentional fall-through via 'default'

I encountered the same error message but don't have any access to the table like "dba_free_space" because I am not a dba. I use some previous answers to check available space and I still have a lot of space. However, after reducing the full table scan as many as possible. The problem is solved. My guess is that Oracle uses temp table to store the full table scan data. It the data size exceeds the limit, it will show the error. Hope this helps someone with the same issue

You need to detect the click from js side, your HTML remaining same. Note: this method is deprecated since v3.5.5 and removed in v4.

$("button").click(function() {
    var $btn = $(this);
    $btn.button('loading');
    // simulating a timeout
    setTimeout(function () {
        $btn.button('reset');
    }, 1000);
});

Also, don't forget to load jQuery and Bootstrap js (based on jQuery) file in your page.

This has happened to me also, after undating to IOS11 on my iPhone. When I try to connect to the corporate network it bring up the corporate cert and says it isn't trusted. I press the 'trust' button and the connection fails and the cert does not appear in the trusted certs list.

I know sounds crazy but I received such error because I forget to remove

after your pc connects to other pc use these 4 step:
4 steps:
1- Edit this file: httpd.conf
for that click on wamp server and select Apache and select httpd.conf
2- Find this text: Deny from all
in the below tag:

     Order Deny,Allow
    Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost
</Directory>

3- Change to: Deny from none
like this:

     Order Deny,Allow
    Deny from none
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

4- Restart Apache
Don't forget restart Apache or all servises!!!

You can append a select statement to your insert statement. Integer myInt = Insert into table1 (FName) values('Fred'); Select Scope_Identity(); This will return a value of the identity when executed scaler.

Usually this happens if something is wrong with the byte array.

File.WriteAllBytes("filename.PDF", Byte[]);

This creates a new file, writes the specified byte array to the file, and then closes the file. If the target file already exists, it is overwritten.

Asynchronous implementation of this is also available.

public static System.Threading.Tasks.Task WriteAllBytesAsync 
(string path, byte[] bytes, System.Threading.CancellationToken cancellationToken = null);

A blanket "no you shouldn't" is terrible advice. This is perfectly reasonable in many situations depending on your use case, workload, data entropy, hardware, etc.. What you shouldn't do is make assumptions.

It should be noted that you can specify a prefix which will limit MySQL's indexing, thereby giving you some help in narrowing down the results before scanning the rest. This may, however, become less useful over time as your prefix "fills up" and becomes less unique.

It's very simple to do, e.g.:

CREATE TABLE IF NOT EXISTS `foo` (
  `id` varchar(128),
  PRIMARY KEY (`id`(4))
)

Also note that the prefix (4) appears after the column quotes. Where the 4 means that it should use the first 4 characters of the 128 possible characters that can exist as the id.

Lastly, you should read how index prefixes work and their limitations before using them: https://dev.mysql.com/doc/refman/8.0/en/create-index.html

If you did literally this:

encodeURIComponent('&')

Then the result is %26, you can test it here. Make sure the string you are encoding is just & and not & to begin with...otherwise it is encoding correctly, which is likely the case. If you need a different result for some reason, you can do a .replace(/&/g,'&') before the encoding.

Without JQuery

HTML:

<INPUT type="file" class="custom-file-input"  onchange="return onChangeFileInput(this);">

JS:

function onChangeFileInput(elem){
  var sibling = elem.nextSibling.nextSibling;
  sibling.innerHTML=elem.value;
  return true;
}

KliG

Better use:

sock.bind((MCAST_GRP, MCAST_PORT))

instead of:

sock.bind(('', MCAST_PORT))

because, if you want to listen to multiple multicast groups on the same port, you'll get all messages on all listeners.

Visual mode map example to add single quotes around a selected block of text:

:vnoremap qq <Esc>`>a'<Esc>`<i'<Esc>

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

try some thing like blow:

SString otherParametersUrServiceNeed =  "Company=acompany&Lng=test&MainPeriod=test&UserID=123&CourseDate=8:10:10";
String request = "http://android.schoolportal.gr/Service.svc/SaveValues";

URL url = new URL(request); 
HttpURLConnection connection = (HttpURLConnection) url.openConnection();   
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setInstanceFollowRedirects(false); 
connection.setRequestMethod("POST"); 
connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); 
connection.setRequestProperty("charset", "utf-8");
connection.setRequestProperty("Content-Length", "" + Integer.toString(otherParametersUrServiceNeed.getBytes().length));
connection.setUseCaches (false);

DataOutputStream wr = new DataOutputStream(connection.getOutputStream ());
wr.writeBytes(otherParametersUrServiceNeed);

   JSONObject jsonParam = new JSONObject();
jsonParam.put("ID", "25");
jsonParam.put("description", "Real");
jsonParam.put("enable", "true");

wr.writeBytes(jsonParam.toString());

wr.flush();
wr.close();

The objects in the std::set are stored as const StudentT. So when you try to call getId() with the const object the compiler detects a problem, mainly you're calling a non-const member function on const object which is not allowed because non-const member functions make NO PROMISE not to modify the object; so the compiler is going to make a safe assumption that getId() might attempt to modify the object but at the same time, it also notices that the object is const; so any attempt to modify the const object should be an error. Hence compiler generates an error message.

The solution is simple: make the functions const as:

int getId() const {
    return id;
}
string getName() const {
    return name;
}

This is necessary because now you can call getId() and getName() on const objects as:

void f(const StudentT & s)
{
     cout << s.getId();   //now okay, but error with your versions
     cout << s.getName(); //now okay, but error with your versions
}

As a sidenote, you should implement operator< as :

inline bool operator< (const StudentT & s1, const StudentT & s2)
{
    return  s1.getId() < s2.getId();
}

Note parameters are now const reference.

A possibility is that the git server you are pushing to is down/crashed, and the solution lies in restarting the git server.

instanceof works for instences of the same class or its subclasses

You can use it to test if an object is an instance of a class, an instance of a subclass, or an instance of a class that implements a particular interface.

ArryaList and RoleList are both instanceof List

While

getClass() == o.getClass() will be true only if both objects ( this and o ) belongs to exactly the same class.

So depending on what you need to compare you could use one or the other.

If your logic is: "One objects is equals to other only if they are both the same class" you should go for the "equals", which I think is most of the cases.

Passing arguments is easy, and receiving them is just a matter of reading the process.argv array Node makes accessible from everywhere, basically. But you're sure to want to read them as key/value pairs, so you'll need a piece to script to interpret it.

Joseph Merdrignac posted a beautiful one using reduce, but it relied on a key=value syntax instead of -k value and --key value. I rewrote it much uglier and longer to use that second standard, and I'll post it as an answer because it wouldn't fit as a commentary. But it does get the job done.

   const args = process.argv.slice(2).reduce((acc,arg,cur,arr)=>{
     if(arg.match(/^--/)){
       acc[arg.substring(2)] = true
       acc['_lastkey'] = arg.substring(2)
     } else
     if(arg.match(/^-[^-]/)){
       for(key of arg.substring(1).split('')){
         acc[key] = true
         acc['_lastkey'] = key
       }
     } else
       if(acc['_lastkey']){
         acc[acc['_lastkey']] = arg
         delete acc['_lastkey']
       } else
         acc[arg] = true
     if(cur==arr.length-1)
       delete acc['_lastkey']
     return acc
   },{})

With this code a command node script.js alpha beta -charlie delta --echo foxtrot would give you the following object

args = {
 "alpha":true,
 "beta":true,
 "c":true,
 "h":true,
 "a":true,
 "r":true
 "l":true,
 "i":true,
 "e":"delta",
 "echo":"foxtrot"
}

While it's good to read and understand Josh's answer, you'll probably be happier using the class Microsoft provided for this purpose: System.Collections.BitArray It's available in all versions of .NET Framework.

The easiest way is to add a type to the variable that is receiving the value, like this:

var value: string = (event.target as any).value;

Or you could cast the value property as well as event.target like this:

var value = ((event.target as any).value as string);

Edit:

Lastly, you can define what EventTarget.value is in a separate .d.ts file. However, the type will have to be compatible where it's used elsewhere, and you'll just end up using any again anyway.

globals.d.ts

interface EventTarget {
    value: any;
}

Well, the basic premise here is: no, it is not secure yet.

Basically, you can't run crypto in JavaScript: JavaScript Crypto Considered Harmful.

The problem is that you can't reliably get the crypto code into the browser, and even if you could, JS isn't designed to let you run it securely. So until browsers have a cryptographic container (which Encrypted Media Extensions provide, but are being rallied against for their DRM purposes), it will not be possible to do securely.

As far as a "Better way", there isn't one right now. Your only alternative is to store the data in plain text, and hope for the best. Or don't store the information at all. Either way.

Either that, or if you need that sort of security, and you need local storage, create a custom application...

SELECT User FROM mysql.user;

use above query to get Mysql Users

For e.g. when a user has login.Now lets say the user want to create a forum topic, How will I know that the user is already logged in?

Think about it - there must be some handshake that tells your "Create Forum" API that this current request is from an authenticated user. Since REST APIs are typically stateless, the state must be persisted somewhere. Your client consuming the REST APIs is responsible for maintaining that state. Usually, it is in the form of some token that gets passed around since the time the user was logged in. If the token is good, your request is good.

Check how Amazon AWS does authentications. That's a perfect example of "passing the buck" around from one API to another.

*I thought of adding some practical response to my previous answer. Try Apache Shiro (or any authentication/authorization library). Bottom line, try and avoid custom coding. Once you have integrated your favorite library (I use Apache Shiro, btw) you can then do the following:

1. Create a Login/logout API like: /api/v1/login and api/v1/logout
2. In these Login and Logout APIs, perform the authentication with your user store
3. The outcome is a token (usually, JSESSIONID) that is sent back to the client (web, mobile, whatever)
4. From this point onwards, all subsequent calls made by your client will include this token
5. Let's say your next call is made to an API called /api/v1/findUser
6. The first thing this API code will do is to check for the token ("is this user authenticated?")
7. If the answer comes back as NO, then you throw a HTTP 401 Status back at the client. Let them handle it.
8. If the answer is YES, then proceed to return the requested User

That's all. Hope this helps.

You can do this faster using a nearly optimal trial division sieve in one (long) line like this:

Enumerable.Range(0, Math.Floor(2.52*Math.Sqrt(num)/Math.Log(num))).Aggregate(
    Enumerable.Range(2, num-1).ToList(), 
    (result, index) => { 
        var bp = result[index]; var sqr = bp * bp;
        result.RemoveAll(i => i >= sqr && i % bp == 0); 
        return result; 
    }
);

The approximation formula for number of primes used here is p(x) < 1.26 x / ln(x). We only need to test by primes not greater than x = sqrt(num).

Note that the sieve of Eratosthenes has much better run time complexity than trial division (should run much faster for bigger num values, when properly implemented).

Dan Beaulieu's answer in swift5 (also working since swift 3.0.1).

Swift 5.0.1

extension DispatchQueue {

    static func background(delay: Double = 0.0, background: (()->Void)? = nil, completion: (() -> Void)? = nil) {
        DispatchQueue.global(qos: .background).async {
            background?()
            if let completion = completion {
                DispatchQueue.main.asyncAfter(deadline: .now() + delay, execute: {
                    completion()
                })
            }
        }
    }

}

Usage

DispatchQueue.background(delay: 3.0, background: {
    // do something in background
}, completion: {
    // when background job finishes, wait 3 seconds and do something in main thread
})

DispatchQueue.background(background: {
    // do something in background
}, completion:{
    // when background job finished, do something in main thread
})

DispatchQueue.background(delay: 3.0, completion:{
    // do something in main thread after 3 seconds
})

I think I had a better output, especially for a double datatype sorting.

Though this question has been marked answered, perhaps this will help someone else;

Arrays.sort(newTag, new Comparator<String[]>() {
         @Override
         public int compare(final String[] entry1, final String[] entry2) {
              final Integer time1 = (int)Integer.valueOf((int) Double.parseDouble(entry1[2]));
              final Integer time2 = (int)Integer.valueOf((int) Double.parseDouble(entry2[2]));
              return time1.compareTo(time2);
         }
    });

Yeah I had the same problem and it was driving me crazy because I couldn't find the image.

This may help you out...

1. Look for a CSS file in your directories called jquery-ui.css
2. Open it up and search for ui-bg_flat_75_ffffff_40x100.png.

You will then see something like this...

.ui-widget-content {
    border: 1px solid #aaaaaa;
    background: #ffffff url(images/ui-bg_flat_75_ffffff_40x100.png) 50% 50% repeat-x;
    color: #222222;
}

And comment out the background and save the CSS document. Or you can set an absolute path to that background property and see if that works for you. (i.e. background: #ffffff url(http://.../image.png);

Hope this helps

I came here looking for the answer to this on OSX. I ended up getting what I wanted with bash and awk:

topfiltered() {

  dump="/tmp/top_dump"
  rm -f "$dump"
  while :; do
    clear

}

I loop top in logging mode and filter it with awk, building an associative array from the output of pgrep. Awk prints the first 12 lines, where line 12 is the column headers, and then every line which has a pid that's a key in the array. The dump file is used for a more watchable loop.

You can create a MemoryStream from a String and use that in any third-party function that requires a stream. In this case, MemoryStream, with the help of UTF8.GetBytes, provides the functionality of Java's StringStream.

From String examples

String content = "stuff";
using (MemoryStream stream = new MemoryStream(System.Text.Encoding.UTF8.GetBytes(content)))
{
    Print(stream); //or whatever action you need to perform with the stream
    stream.Seek(0, SeekOrigin.Begin); //If you need to use the same stream again, don't forget to reset it.
    UseAgain(stream);
}

To String example

stream.Seek(0, SeekOrigin.Begin);
string s;
using (var readr = new StreamReader(stream))
{
    s = readr.ReadToEnd();
}
//and don't forget to dispose the stream if you created it

This parameter is is working for me:

--enable-easy-off-store-extension-install

Do the following:

1. Right click on your "Chrome" icon.
2. Choose properties
3. At the end of your target line, place these parameters: --enable-easy-off-store-extension-install
4. It should look like: chrome.exe --enable-easy-off-store-extension-install
5. Start Chrome by double-clicking on the icon

add a space before the close bracket

You can't. New browsers like Firefox, Safari etc. block the 'file' protocol. It will only work on old browsers.

You'll have to upload the files you want.

First of all, let's try to make your code a little simpler:

// No need to create a circle unless it is clearly necessary to
// demonstrate the problem

// Your Rect2f defines a default constructor, so let's use it for simplicity.
shared_ptr<Shape> rect(new Rect2f());

Okay, so now we see that the parentheses are clearly balanced. What else could it be? Let's check the following code snippet's error:

int main() {
    delete new T();
}

This may seem like weird usage, and it is, but I really hate memory leaks. However, the output does seem useful:

In function 'int main()':
Line 2: error: expected type-specifier before 'T'

Aha! Now we're just left with the error about the parentheses. I can't find what causes that; however, I think you are forgetting to include the file that defines Rect2f.

use Illuminate\Database\Eloquent\Builder;

$query = Customers::with('orders');
$query = $query->whereHas('orders', function (Builder $query) use ($request) {
     $query = $query->where('orders.customer_id', 'NULL') 
});
    $query = $query->get();

The .htaccess is either in the root-directory of your webpage or in the directory you want to protect.

Make sure to make them visible in your filesystem, because AFAIK (I'm no unix expert either) files starting with a period are invisible by default on unix-systems.

CENTERING THE WINDOW IN PYTHON Tkinter This is the most easiest thing in tkinter because all we must know is the dimension of the window as well as the dimensions of the computer screen. I come up with the following code which can help someone somehow and i did add some comments so that they can follow up.

code

    #  create a window first
    root = Tk()
    # define window dimensions width and height
    window_width = 800
    window_height = 500
    # get the screen size of your computer [width and height using the root object as foolows]
    screen_width = root.winfo_screenwidth()
    screen_height = root.winfo_screenheight()
    # Get the window position from the top dynamically as well as position from left or right as follows
    position_top = int(screen_height/2 -window_height/2)
    position_right = int(screen_width / 2 - window_width/2)
    # this is the line that will center your window
    root.geometry(f'{window_width}x{window_height}+{position_right}+{position_top}')
    # initialise the window
    root.mainloop(0)

The scalar formatter supports collecting the exponents. The docs are as follows:

class matplotlib.ticker.ScalarFormatter(useOffset=True, useMathText=False, useLocale=None) Bases: matplotlib.ticker.Formatter

Tick location is a plain old number. If useOffset==True and the data range is much smaller than the data average, then an offset will be determined such that the tick labels are meaningful. Scientific notation is used for data < 10^-n or data >= 10^m, where n and m are the power limits set using set_powerlimits((n,m)). The defaults for these are controlled by the axes.formatter.limits rc parameter.

your technique would be:

from matplotlib.ticker import ScalarFormatter
xfmt = ScalarFormatter()
xfmt.set_powerlimits((-3,3))  # Or whatever your limits are . . .
{{ Make your plot }}
gca().xaxis.set_major_formatter(xfmt)

To get the exponent displayed in the format x10^5, instantiate the ScalarFormatter with useMathText=True.

You could also use:

xfmt.set_useOffset(10000)

To get a result like this:

You have a truncated array representation. Let's look at a full example:

>>> a = np.zeros((2, 3, 4))
>>> a
array([[[ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.]],

       [[ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.],
        [ 0.,  0.,  0.,  0.]]])

Arrays in NumPy are printed as the word array followed by structure, similar to embedded Python lists. Let's create a similar list:

>>> l = [[[ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.]],

          [[ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.],
          [ 0.,  0.,  0.,  0.]]]

>>> l
[[[0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0]], 
 [[0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0], [0.0, 0.0, 0.0, 0.0]]]

The first level of this compound list l has exactly 2 elements, just as the first dimension of the array a (# of rows). Each of these elements is itself a list with 3 elements, which is equal to the second dimension of a (# of columns). Finally, the most nested lists have 4 elements each, same as the third dimension of a (depth/# of colors).

So you've got exactly the same structure (in terms of dimensions) as in Matlab, just printed in another way.

Some caveats:

1. Matlab stores data column by column ("Fortran order"), while NumPy by default stores them row by row ("C order"). This doesn't affect indexing, but may affect performance. For example, in Matlab efficient loop will be over columns (e.g. for n = 1:10 a(:, n) end), while in NumPy it's preferable to iterate over rows (e.g. for n in range(10): a[n, :] -- note n in the first position, not the last).

2. If you work with colored images in OpenCV, remember that:

   2.1. It stores images in BGR format and not RGB, like most Python libraries do.

   2.2. Most functions work on image coordinates (x, y), which are opposite to matrix coordinates (i, j).

You are confusing 'sets' and 'lists'. A set does not guarantee order, but lists do.

Sets are declared using curly brackets: {}. In contrast, lists are declared using square brackets: [].

mySet = {a, b, c, c}

Does not guarantee order, but list does:

myList = [a, b, c]

Had the same problem...im also new at javascript but i solved this with req.connection.remoteAddress; that gave me th IP address (but in ipv6 format ::ffff.192.168.0.101 ) and then .slice to remove the 7 first digits.

var ip = req.connection.remoteAddress;

if (ip.length < 15) 
{   
   ip = ip;
}
else
{
   var nyIP = ip.slice(7);
   ip = nyIP;
}

In many cases an element must be positioned for z-index to work.

Indeed, applying position: relative to the elements in the question would likely solve the problem (but there's not enough code provided to know for sure).

Actually, position: fixed, position: absolute and position: sticky will also enable z-index, but those values also change the layout. With position: relative the layout isn't disturbed.

Essentially, as long as the element isn't position: static (the default setting) it is considered positioned and z-index will work.

Many answers to "Why isn't z-index working?" questions assert that z-index only works on positioned elements. As of CSS3, this is no longer true.

Elements that are flex items or grid items can use z-index even when position is static.

From the specs:

4.3. Flex Item Z-Ordering

Flex items paint exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

5.4. Z-axis Ordering: the z-index property

The painting order of grid items is exactly the same as inline blocks, except that order-modified document order is used in place of raw document order, and z-index values other than auto create a stacking context even if position is static.

Here's a demonstration of z-index working on non-positioned flex items: https://jsfiddle.net/m0wddwxs/

<%
String session_val = (String)session.getAttribute("sessionval"); 
System.out.println("session_val"+session_val);
%>
<html>
<head>
<script type="text/javascript">
var session_obj= '<%=session_val%>';
alert("session_obj"+session_obj);
</script>
</head>
</html>

This is, IMHO, the most generic and robust solution (if your actions are user-triggered, eg 'user clicks on a button'):

• the first time a handler is called check WHO triggered it:
  • if a user tiggered it - do your stuff, and then trigger it again (if you want) - programmatically
  • otherwise - do nothing (= "continue default")

As an example, note this elegant solution to adding "Are you sure?" popup to any button just by decorating a button with an attribute. We will conditionally continue default behavior if the user doesn't opt out.

1. Let's add to every button that we want an "are you sure" popup a warning text:

<button class="btn btn-success-outline float-right" type="submit"  ays_text="You will lose any unsaved changes... Do you want to continue?"                >Do something dangerous</button>

2. Attach handlers to ALL such buttons:

$('button[ays_text]').click(function (e, from) {
    if (from == null) {  // user clicked it!
        var btn = $(this);
        e.preventDefault();
        if (confirm() == true) {
            btn.trigger('click', ['your-app-name-here-or-anything-that-is-not-null']);
        }
    }
    // otherwise - do nothing, ie continue default
});

That's it.

After 3 hours of searching and investigation.

I had problems with it because we have two members in team (using GitHub source control), because we didn't restrict files for packages for sending to remote repository, one of team members was send packages to server and i have pull that changes to my local.

After that i had same problem as PO, also i wasn't be able to publish my API project to server.

At the and I have just used

Update-Package -Reinstall - run this command on Package Manager Console

This command will reinstall all your packages that you have used in your solution. (For every project)

Reinstall all packages in ALL PROJECTS of the current solution:

Update-Package -ProjectName 'NameOfProject' -Reinstall - run this command on Package Manager Console

This command will reinstall all your packages that are in relation with project that you specified after "-ProjectName". And i think that this is better because i had wait for half a hour to reinstall all packages in solution.

For this many thanks to Rodolpho Brock.

Also, I would recommend you that when you pull changes from remote server, to press "Restore packages" button that will be shown by Visual studio.

I was facing with this problem some time ago and I found java.util.LinkedList is best for my case. It has several methods, with different namings, but they're doing what is needed:

push()    -> LinkedList.addLast(); // Or just LinkedList.add();
pop()     -> LinkedList.pollLast();
shift()   -> LinkedList.pollFirst();
unshift() -> LinkedList.addFirst();

PHP Arrays don't need to be declared with a size.

An array in PHP is actually an ordered map

You also shouldn't get a warning/notice using code like the example you have shown. The common Notice people get is "Undefined offset" when reading from an array.

A way to counter this is to check with isset or array_key_exists, or to use a function such as:

function isset_or($array, $key, $default = NULL) {
    return isset($array[$key]) ? $array[$key] : $default;
}

So that you can avoid the repeated code.

Note: isset returns false if the element in the array is NULL, but has a performance gain over array_key_exists.

If you want to specify an array with a size for performance reasons, look at:

SplFixedArray in the Standard PHP Library.

First of all, a modified version of your service.

a )

var app = angular.module('app',[]);

app.factory('ExampleService',function(){
    return {
        f1 : function(world){
            return 'Hello' + world;
        }
    };
});

This returns an object, nothing to new here.

Now the way to get this from the console is

b )

var $inj = angular.injector(['app']);
var serv = $inj.get('ExampleService');
serv.f1("World");

c )

One of the things you were doing there earlier was to assume that the app.factory returns you the function itself or a new'ed version of it. Which is not the case. In order to get a constructor you would either have to do

app.factory('ExampleService',function(){
        return function(){
            this.f1 = function(world){
                return 'Hello' + world;
            }
        };
    });

This returns an ExampleService constructor which you will next have to do a 'new' on.

Or alternatively,

app.service('ExampleService',function(){
            this.f1 = function(world){
                return 'Hello' + world;
            };
    });

This returns new ExampleService() on injection.

In Chrome, right click in the console and check 'preserve log on navigation'.

You have to put all your assets in app/public folder, and to access them from your views you can use asset() helper method.

Ex. you can retrieve assets/images/image.png in your view as following:

<img src="{{asset('assets/images/image.png')}}">

The standalone declaration is a way of telling the parser to ignore any markup declarations in the DTD. The DTD is thereafter used for validation only.

As an example, consider the humble <img> tag. If you look at the XHTML 1.0 DTD, you see a markup declaration telling the parser that <img> tags must be EMPTY and possess src and alt attributes. When a browser is going through an XHTML 1.0 document and finds an <img> tag, it should notice that the DTD requires src and alt attributes and add them if they are not present. It will also self-close the <img> tag since it is supposed to be EMPTY. This is what the XML specification means by "markup declarations can affect the content of the document." You can then use the standalone declaration to tell the parser to ignore these rules.

Whether or not your parser actually does this is another question, but a standards-compliant validating parser (like a browser) should.

Note that if you do not specify a DTD, then the standalone declaration "has no meaning," so there's no reason to use it unless you also specify a DTD.

I have a similar case. I need to install openssl via brew and then use pip to install mitmproxy. I get the same complaint from brew link --force. Following is the solution I reached: (without force link by brew)

LDFLAGS=-L/usr/local/opt/openssl/lib 
CPPFLAGS=-I/usr/local/opt/openssl/include
PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig 
pip install mitmproxy

This does not address the question straightforwardly. I leave the one-liner in case anyone uses pip and requires the openssl lib.

Note: the /usr/local/opt/openssl/lib paths are obtained by brew info openssl

Basically, you have two major choices:

• You can generate the identifier yourself, in which case you can use an assigned identifier.
• You can use the @GeneratedValue annotation and Hibernate will assign the identifier for you.

For the generated identifiers you have two options:

• UUID identifiers.
• Numerical identifiers.

For numerical identifiers you have three options:

• IDENTITY
• SEQUENCE
• TABLE

IDENTITY is only a good choice when you cannot use SEQUENCE (e.g. MySQL) because it disables JDBC batch updates.

SEQUENCE is the preferred option, especially when used with an identifier optimizer like pooled or pooled-lo.

TABLE is to be avoided since it uses a separate transaction to fetch the identifier and row-level locks which scales poorly.

This:

 lst = [8 for i in range(9)]

creates a list, elements are initialized 8

but this:

lst = [0] * 7

would create 7 lists which have one element

The simplest way that doesn't require third party libraries it to create a URL object and then call either openConnection or openStream on it. Note that this is a pretty basic API, so you won't have a lot of control over the headers.

I was facing a similar issue, I had a file on my project, and wanted to test a class which had to deal with loading files from the FS and process them some way. What I did was:

• added the file test.txt to my test project
• on the solution explorer hit alt-enter (file properties)
• there I set BuildAction to Content and Copy to Output Directory to Copy if newer, I guess Copy always would have done it as well

then on my tests I just had to Path.Combine(Environment.CurrentDirectory, "test.txt") and that's it. Whenever the project is compiled it will copy the file (and all it's parent path, in case it was in, say, a folder) to the bin\Debug (or whatever configuration you are using) folder.

Hopes this helps someone

When slicing in Python the third parameter is the step. As others mentioned, see Extended Slices for a nice overview.

With this knowledge, [::3] just means that you have not specified any start or end indices for your slice. Since you have specified a step, 3, this will take every third entry of something starting at the first index. For example:

>>> '123123123'[::3]
'111'

For anyone else who gets caught, ensure setCustomAnimations is called before the call to replace/add when building the transaction.

You could do something like this:

HTML

<div class="element">
   <span>Hi, I am Murtaza</span>
</div>

jQuery

$(".element span").text(function(index, text) { 
    return text.replace('am', 'am not'); 
});

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

In NodeJS, Buffer.byteLength is a method specifically for this purpose:

let strLengthInBytes = Buffer.byteLength(str); // str is UTF-8

Note that by default the method assumes the string is in UTF-8 encoding. If a different encoding is required, pass it as the second argument.

In Python 3.6, f-string is much cleaner.

In earlier version:

print("Total score for %s is %s. " % (name, score))

In Python 3.6:

print(f'Total score for {name} is {score}.')

will do.

It is more efficient and elegant.

First I want to thank you for all the good answers and explanations. This is the method I created based upon all your answer to get the base url. I only use it in very rare situations. So there is NOT a big focus on security issues, like XSS attacks. Maybe someone needs it.

// Get base url
function getBaseUrl($array=false) {
    $protocol = "";
    $host = "";
    $port = "";
    $dir = "";  

    // Get protocol
    if(array_key_exists("HTTPS", $_SERVER) && $_SERVER["HTTPS"] != "") {

        return htmlspecialchars($protocol."://".$host.$port.$dir, ENT_QUOTES);

Basically indexOf() is a method belongs to string(array object also), But while calling the function you are passing a number, try to cast it to a string and pass it.

document.getElementById("oset").innerHTML = timeD2C(timeofday + "");

 var timeofday = new Date().getHours() + (new Date().getMinutes()) / 60;_x000D_
_x000D_
_x000D_
_x000D_
_x000D_
 function timeD2C(time) { // Converts 11.5 (decimal) to 11:30 (colon)_x000D_
    var pos = time.indexOf('.');_x000D_
    var hrs = time.substr(1, pos - 1);_x000D_
    var min = (time.substr(pos, 2)) * 60;_x000D_
_x000D_
    if (hrs > 11) {_x000D_
        hrs = (hrs - 12) + ":" + min + " PM";_x000D_
    } else {_x000D_
        hrs += ":" + min + " AM";_x000D_
    }_x000D_
    return hrs;_x000D_
}_x000D_
alert(timeD2C(timeofday+""));

And it is good to do the string conversion inside your function definition,

function timeD2C(time) { 
  time = time + "";
  var pos = time.indexOf('.');

So that the code flow won't break at times when devs forget to pass a string into this function.

The easiest fix for me to see the Result Grid again was to click on Explain Command

[

After that Execution Plan is going to be shown and on the right side you can click on Result Grid

Excerpt from PostgreSQL documentation:

Restricting and cascading deletes are the two most common options. [...] CASCADE specifies that when a referenced row is deleted, row(s) referencing it should be automatically deleted as well.

This means that if you delete a category – referenced by books – the referencing book will also be deleted by ON DELETE CASCADE.

Example:

CREATE SCHEMA shire;

CREATE TABLE shire.clans (
    id serial PRIMARY KEY,
    clan varchar
);

CREATE TABLE shire.hobbits (
    id serial PRIMARY KEY,
    hobbit varchar,
    clan_id integer REFERENCES shire.clans (id) ON DELETE CASCADE
);

DELETE FROM clans will CASCADE to hobbits by REFERENCES.

sauron@mordor> psql
sauron=# SELECT * FROM shire.clans;
 id |    clan    
----+------------
  1 | Baggins
  2 | Gamgi
(2 rows)

sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  1 | Bilbo    |       1
  2 | Frodo    |       1
  3 | Samwise  |       2
(3 rows)

sauron=# DELETE FROM shire.clans WHERE id = 1 RETURNING *;
 id |  clan   
----+---------
  1 | Baggins
(1 row)

DELETE 1
sauron=# SELECT * FROM shire.hobbits;
 id |  hobbit  | clan_id 
----+----------+---------
  3 | Samwise  |       2
(1 row)

If you really need the opposite (checked by the database), you will have to write a trigger!

You can simply use $pull to remove a sub-document. The $pull operator removes from an existing array all instances of a value or values that match a specified condition.

Collection.update({
    _id: parentDocumentId
  }, {
    $pull: {
      subDocument: {
        _id: SubDocumentId
      }
    }
  });

This will find your parent document against given ID and then will remove the element from subDocument which matched the given criteria.

Read more about pull here.

A bit long winded but it works for me: try this::

=SUM(IF(OR(ISBLANK(AU2), NOT(ISERR(YEAR(AU2)))),0,1)
 +IF(OR(ISBLANK(AV2), NOT(ISERR(YEAR(AV2)))),0,1))

first part of if will allow cell to be blank or if there is something in the cell it tries to convert to a year, if there is an error or there is something other than a date result = 1, do the same for each cell and sum the result

Make Sure You're Not Closing Database By using db_close() Before To Running Your Query:

If you're using multiple queries in a script even you're including other pages which contains queries or database connection, then it might be possible that at any place you use db_close() that would close your database connection so make sure you're not doing this mistake in your scripts.

Perhaps this should be the select (if I understand the question correctly)

select user.user_fname, user.user_lname, parent.user_fname, parent.user_lname
... As before

On the model set $incrementing to false

public $incrementing = false;

This will stop it from thinking it is an auto increment field.

Move the data retrieval at the top of the script, and after that use:

<title>Ultan.me - <?php echo htmlspecialchars($title, ENT_QUOTES, 'UTF-8'); ?></title>

I had the same problem you did - didn't find much that worked. The following code, however, works like a charm.

import win32com.client

outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")

inbox = outlook.GetDefaultFolder(6) # "6" refers to the index of a folder - in this case,
                                    # the inbox. You can change that number to reference
                                    # any other folder
messages = inbox.Items
message = messages.GetLast()
body_content = message.body
print body_content

Go to file->export->JAR file, there you may select "Export generated class files and sources" and make sure that your project is selected, and all folder under there are also! Good luck!

There are two types of WITH clauses:

Here is the FizzBuzz in SQL form, using a WITH common table expression (CTE).

;WITH mil AS (
 SELECT TOP 1000000 ROW_NUMBER() OVER ( ORDER BY c.column_id ) [n]
 FROM master.sys.all_columns as c
 CROSS JOIN master.sys.all_columns as c2
)                
 SELECT CASE WHEN n  % 3 = 0 THEN
             CASE WHEN n  % 5 = 0 THEN 'FizzBuzz' ELSE 'Fizz' END
        WHEN n % 5 = 0 THEN 'Buzz'
        ELSE CAST(n AS char(6))
     END + CHAR(13)
 FROM mil

Here is a select statement also using a WITH clause

SELECT * FROM orders WITH (NOLOCK) where order_id = 123

J Bryan Price, a good example, but there are shortcomings

{\"response\":[123, 456, {\"name\":\"John\"}, {\"count\":3}]}

after formatting

{
    "response" : [
        123,
         456,
         {
            "name" : "John"
        },
         {
            "count" : 3
        }
    ]
}

improper bias :(

You can also use window.location.href=window.location.href;

I did it this way: Take backup of your existing database. It will give you a db.zip.tmp and then in command prompt write following

"C:\Program Files (x86)\MySQL\MySQL Server 5.6\bin\mysql.exe" -h localhost -u root -p[password] [new db name] < "C:\Backups\db.zip.tmp"

Indeed, Python does garbage collection through reference counting. As soon as the last reference to an object falls out of scope, it is deleted. In your example:

a = A()
a.kill()

I don't believe there's any way for variable 'a' to implicitly set itself to None.

I don't know how it crazy it looks but it does the job really well

ascii2hex(){ a="$@";s=0000000;printf "$a" | hexdump | grep "^$s"| sed s/' '//g| sed s/^$s//;}

Created this when I was trying to see my name in HEX ;) use how can you use it :)

Is you are in bash shell:

for i in {1..1000}
do
   echo "Welcome $i times"
done

DataRow's are nice in the way that they have their underlying table linked to them. With the underlying table you can verify that a specific row has a specific column in it.

    If DataRow.Table.Columns.Contains("column") Then
        MsgBox("YAY")
    End If

You can use the python sorting functions' key parameter to sort the index array instead.

>>> s = [2, 3, 1, 4, 5, 3]
>>> sorted(range(len(s)), key=lambda k: s[k])
[2, 0, 1, 5, 3, 4]
>>> 

Here is the link ... You must read it.

Deleting an entire folder tree sometimes works and sometimes fails with "Directory not empty" errors. Subsequently attempting to check if the folder still exists can result in "Access Denied" or "Unauthorized Access" errors. I do not know why this happens, though some insight may be gained from this StackOverflow posting.

I have been able to get around these issues by specifying the order in which items within the folder are deleted, and by adding delays. The following runs well for me:

# First remove any files in the folder tree
Get-ChildItem -LiteralPath $FolderToDelete -Recurse -Force | Where-Object { -not ($_.psiscontainer) } | Remove-Item –Force

# Then remove any sub-folders (deepest ones first).    The -Recurse switch may be needed despite the deepest items being deleted first.
ForEach ($Subfolder in Get-ChildItem -LiteralPath $FolderToDelete -Recurse -Force | Select-Object FullName, @{Name="Depth";Expression={($_.FullName -split "\\").Count}} | Sort-Object -Property @{Expression="Depth";Descending=$true}) { Remove-Item -LiteralPath $Subfolder.FullName -Recurse -Force }

# Then remove the folder itself.  The -Recurse switch is sometimes needed despite the previous statements.
Remove-Item -LiteralPath $FolderToDelete -Recurse -Force

# Finally, give Windows some time to finish deleting the folder (try not to hurl)
Start-Sleep -Seconds 4

A Microsoft TechNet article Using Calculated Properties in PowerShell was helpful to me in getting a list of sub-folders sorted by depth.

Similar reliability issues with RD /S /Q can be solved by running DEL /F /S /Q prior to RD /S /Q and running the RD a second time if necessary - ideally with a pause in between (i.e. using ping as shown below).

DEL /F /S /Q "C:\Some\Folder\to\Delete\*.*" > nul
RD /S /Q "C:\Some\Folder\to\Delete" > nul
if exist "C:\Some\Folder\to\Delete"  ping -4 -n 4 127.0.0.1 > nul
if exist "C:\Some\Folder\to\Delete"  RD /S /Q "C:\Some\Folder\to\Delete" > nul

I had same issue. My Json response from the server was having [, and, ]:

[{"DATE_HIRED":852344800000,"FRNG_SUB_ACCT":0,"MOVING_EXP":0,"CURRENCY_CODE":"CAD  ","PIN":"          ","EST_REMUN":0,"HM_DIST_CO":1,"SICK_PAY":0,"STAND_AMT":0,"BSI_GROUP":"           ","LAST_DED_SEQ":36}]

http://jsonlint.com/ says valid json. you can copy and verify it.

I have fixed with below code as temporary solution:

BufferedReader br = new BufferedReader(new InputStreamReader((response.getEntity().getContent())));
String result ="";
String output = null;
while ((result = br.readLine()) != null) {
    output = result.replace("[", "").replace("]", "");
    JSONObject jsonObject = new JSONObject(output); 
    JSONArray jsonArray = new JSONArray(output); 
    .....   
}

I have the same problem: Failed to install test.apk on device 'xxxxxxxxx': null

I try to reboot phone, restart Eclipse, and nothing!

Then, I remove this project from Eclipse workspace, and import again. (File, Import, Existing project to workspace). I do not know exactly what the problem was, but now is working ok.

Yes you can use jquery with Angular 4

Steps:

1) In index.html put below line in tag.

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>

2) In component ts file below you have to declare var like this

import { Component } from '@angular/core';
declare var jquery:any;
declare var $ :any;

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angular 4 with jquery';
  toggleTitle(){
    $('.title').slideToggle(); //
  }

}

And use this code for corresponding html file like this:

<h1 class="title" style="display:none">
  {{title}}
</h1>
<button (click)="toggleTitle()"> clickhere</button>

This will work for you. Thanks

Note that if you're using Sublime as your commit editor, you need the -n -w flags, otherwise git keeps thinking your commit message is empty and aborting.

Perhaps the most useful extension methods I've written and used are here:

http://www.codeproject.com/KB/cs/fun-with-cs-extensions.aspx?msg=2838918#xx2838918xx

There does exist a split function based on regular expressions. It's not listed in the tutorial, but it is listed on the language manual on the wiki:

split(string str, string pat)
   Split str around pat (pat is a regular expression) 

In your case, the delimiter "|" has a special meaning as a regular expression, so it should be referred to as "\\|".

Use this query:

UPDATE `table` SET date_date=now();

Sample code can be:

<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("my_db", $con);

mysql_query("UPDATE `table` SET date_date=now()");

mysql_close($con);
?>

This should do the job:

diff -rq dir1 dir2

Options explained (via diff(1) man page):

• -r - Recursively compare any subdirectories found.
• -q - Output only whether files differ.

I usually attach a class to the element then check if the class exist like this:

let element = document.getElementsById("someElement");

if(!element.classList.contains('attached-listener'))
   element.addEventListener("click", this.itemClicked);

element.classList.add('attached-listener');

I know this is not an ideal question to answer but as the OP seems to be a beginner, I'd love to share some basic knowledge with him... Hope everybody understands

OP, you can convert a string to type Boolean by using any of the methods stated below:

 string sample = "True";
 bool myBool = bool.Parse(sample);

 ///or

 bool myBool = Convert.ToBoolean(sample);

bool.Parse expects one parameter which in this case is sample, .ToBoolean also expects one parameter.

You can use TryParse which is the same as Parse but it doesn't throw any exception :)

  string sample = "false";
  Boolean myBool;

  if (Boolean.TryParse(sample , out myBool))
  {
  }

Please note that you cannot convert any type of string to type Boolean because the value of a Boolean can only be True or False

Hope you understand :)

I want to complete the answer from tchester.

(1) Enable the xp_cmdshell procedure:

-- To allow advanced options to be changed.
EXEC sp_configure 'show advanced options', 1
RECONFIGURE
GO

-- Enable the xp_cmdshell procedure
EXEC sp_configure 'xp_cmdshell', 1
RECONFIGURE
GO

(2) Create a login 'Domain\TestUser' (windows user) for the non-sysadmin user that has public access to the master database

(3) Grant EXEC permission on the xp_cmdshell stored procedure:

GRANT EXECUTE ON xp_cmdshell TO [Domain\TestUser]

(4) Create a proxy account that xp_cmdshell will be run under using sp_xp_cmdshell_proxy_account

EXEC sp_xp_cmdshell_proxy_account 'Domain\TestUser', 'pwd'
-- Note: pwd means windows password for [Domain\TestUser] account id on the box.
--       Don't include square brackets around Domain\TestUser.

(5) Grant control server permission to user

USE master;
GRANT CONTROL SERVER TO [Domain\TestUser]
GO

Use a semaphore with a count that is equal to the number of readers. Let each reader take one count of the semaphore in order to read, that way they can all read at the same time. Then let the writer take ALL the semaphore counts prior to writing. This causes the writer to wait for all reads to finish and then block out reads while writing.

The problem is that you are using SingleOrDefault. This method will only succeed when the collections contains exactly 0 or 1 element. I believe you are looking for FirstOrDefault which will succeed no matter how many elements are in the collection.

For tomcat you can increase the permGem space by using

 -XX:MaxPermSize=128m

For this you need to create (if not already exists) a file named setenv.sh in tomcat/bin folder and include following line in it

   export JAVA_OPTS="-XX:MaxPermSize=128m"

Reference : http://wiki.razuna.com/display/ecp/Adjusting+Memory+Settings+for+Tomcat

To set permission on the data folder and all it's subfolders and files:
Open command prompt from the ADB folder:

>> adb shell
>> su
>> find /data -type d -exec chmod 777 {} \;

You cannot clear the browser history. It belongs to the user, not the developer. Also have a look at the MDN documentation.

Update: The link you were posting all over does not actually clear your browser history. It just prevents using the back button.

You could convert it to a string instead of printing the list directly:

print(", ".join(LIST))

If the elements in the list aren't strings, you can convert them to string using either repr (if you want quotes around strings) or str (if you don't), like so:

LIST = [1, "foo", 3.5, { "hello": "bye" }]
print( ", ".join( repr(e) for e in LIST ) )

Which gives the output:

1, 'foo', 3.5, {'hello': 'bye'}

Allen Holub's "Enough Rope to Shoot Yourself in the Foot" lists the following 2 rules:

120. Reference arguments should always be `const`
121. Never use references as outputs, use pointers

He lists several reasons why references were added to C++:

• they are necessary to define copy constructors
• they are necessary for operator overloads
• const references allow you to have pass-by-value semantics while avoiding a copy

His main point is that references should not be used as 'output' parameters because at the call site there's no indication of whether the parameter is a reference or a value parameter. So his rule is to only use const references as arguments.

Personally, I think this is a good rule of thumb as it makes it more clear when a parameter is an output parameter or not. However, while I personally agree with this in general, I do allow myself to be swayed by the opinions of others on my team if they argue for output parameters as references (some developers like them immensely).

Personally,I prefer to use preg_match() function:

if(preg_match("/\.(gif|png|jpg)$/", $filename))

or in_array()

$exts = array('gif', 'png', 'jpg'); 
if(in_array(end(explode('.', $filename)), $exts)

With in_array() can be useful if you have a lot of extensions to validate and perfomance question. Another way to validade file images: you can use @imagecreatefrom*(), if the function fails, this mean the image is not valid.

For example:

function testimage($path)
{
   if(!preg_match("/\.(png|jpg|gif)$/",$path,$ext)) return 0;
   $ret = null;
   switch($ext)
   {
       case 'png': $ret = @imagecreatefrompng($path); break;
       case 'jpeg': $ret = @imagecreatefromjpeg($path); break;
       // ...
       default: $ret = 0;
   }

   return $ret;
}

then:

$valid = testimage('foo.png');

Assuming that foo.png is a PHP-script file with .png extension, the above function fails. It can avoid attacks like shell update and LFI.

Assuming that your profile in ~/aws/config is using the region (instead of AZ as per your original question); the other cause is your client's inability to connect to s3.us-east-1.amazonaws.com. In my case, I was unable to resolve that DNS name due to an error in my network configuration. Fixing the DNS issue solved my problem.

As said before, with JPA, in order to have the chance to have extra columns, you need to use two OneToMany associations, instead of a single ManyToMany relationship. You can also add a column with autogenerated values; this way, it can work as the primary key of the table, if useful.

For instance, the implementation code of the extra class should look like that:

@Entity
@Table(name = "USER_SERVICES")
public class UserService{

    // example of auto-generated ID
    @Id
    @Column(name = "USER_SERVICES_ID", nullable = false)
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private long userServiceID;



    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "USER_ID")
    private User user;

    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "SERVICE_ID")
    private Service service;



    // example of extra column
    @Column(name="VISIBILITY")    
    private boolean visibility;



    public long getUserServiceID() {
        return userServiceID;
    }


    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }

    public Service getService() {
        return service;
    }

    public void setService(Service service) {
        this.service = service;
    }

    public boolean getVisibility() {
        return visibility;
    }

    public void setVisibility(boolean visibility) {
        this.visibility = visibility;
    }

}

Here's a way I've used in the past. Please note that you have to add a reference to the Microsoft Scripting Runtime so you can use the Dictionary object - if you don't want to add that reference you can do this with Collections but they're slower and there's no elegant way to check .Exists (you have to trap the error).

Dim OldVals As New Dictionary
Private Sub Worksheet_Change(ByVal Target As Range)
Dim cell As Range
    For Each cell In Target
        If OldVals.Exists(cell.Address) Then
            Debug.Print "New value of " & cell.Address & " is " & cell.Value & "; old value was " & OldVals(cell.Address)
        Else
            Debug.Print "No old value for " + cell.Address
        End If
        OldVals(cell.Address) = cell.Value
    Next
End Sub

Like any similar method, this has its problems - first off, it won't know the "old" value until the value has actually been changed. To fix this you'd need to trap the Open event on the workbook and go through Sheet.UsedRange populating OldVals. Also, it will lose all its data if you reset the VBA project by stopping the debugger or some such.

Here are the two main approaches. I prefer this one for its readability:

bar <- subset(foo, location == "there")

Note that you can string together many conditionals with & and | to create complex subsets.

The second is the indexing approach. You can index rows in R with either numeric, or boolean slices. foo$location == "there" returns a vector of T and F values that is the same length as the rows of foo. You can do this to return only rows where the condition returns true.

foo[foo$location == "there", ]

edtFTPnet is a free, fast, open source FTP library for .NET, written in C#.

Since @OscarLopez and I have different opinions on what the second largest means, I'll post the code according to my interpretation and in line with the first algorithm provided by the questioner.

def second_largest(numbers):
    count = 0
    m1 = m2 = float('-inf')
    for x in numbers:
        count += 1
        if x > m2:
            if x >= m1:
                m1, m2 = x, m1            
            else:
                m2 = x
    return m2 if count >= 2 else None

(Note: Negative infinity is used here instead of None since None has different sorting behavior in Python 2 and 3 – see Python - Find second smallest number; a check for the number of elements in numbers makes sure that negative infinity won't be returned when the actual answer is undefined.)

If the maximum occurs multiple times, it may be the second largest as well. Another thing about this approach is that it works correctly if there are less than two elements; then there is no second largest.

Running the same tests:

second_largest([20,67,3,2.6,7,74,2.8,90.8,52.8,4,3,2,5,7])
=> 74
second_largest([1,1,1,1,1,2])
=> 1
second_largest([2,2,2,2,2,1])
=> 2
second_largest([10,7,10])
=> 10
second_largest([1,1,1,1,1,1])
=> 1
second_largest([1])
=> None
second_largest([])
=> None

Update

I restructured the conditionals to drastically improve performance; almost by a 100% in my testing on random numbers. The reason for this is that in the original version, the elif was always evaluated in the likely event that the next number is not the largest in the list. In other words, for practically every number in the list, two comparisons were made, whereas one comparison mostly suffices – if the number is not larger than the second largest, it's not larger than the largest either.

Enter the following command in the directory you want to modify the right:

for example the directory: /var/www/html

sudo setfacl -m g:username:rwx . #-> for file

sudo setfacl -d -m g:username: rwx . #-> for directory

This will solve the problem.

Replace username with your username.

You can use Gson .

Example

Step 1

Add compile

compile 'com.google.code.gson:gson:2.8.2'

Step 2

Convert json to Kotlin Bean(use JsonToKotlinClass)

Like this

Json data

{
"timestamp": "2018-02-13 15:45:45",
"code": "OK",
"message": "user info",
"path": "/user/info",
"data": {
    "userId": 8,
    "avatar": "/uploads/image/20180115/1516009286213053126.jpeg",
    "nickname": "",
    "gender": 0,
    "birthday": 1525968000000,
    "age": 0,
    "province": "",
    "city": "",
    "district": "",
    "workStatus": "Student",
    "userType": 0
},
"errorDetail": null
}

Kotlin Bean

class MineUserEntity {

    data class MineUserInfo(
        val timestamp: String,
        val code: String,
        val message: String,
        val path: String,
        val data: Data,
        val errorDetail: Any
    )

    data class Data(
        val userId: Int,
        val avatar: String,
        val nickname: String,
        val gender: Int,
        val birthday: Long,
        val age: Int,
        val province: String,
        val city: String,
        val district: String,
        val workStatus: String,
        val userType: Int
    )
}

Step 3

Use Gson

var gson = Gson()
var mMineUserEntity = gson?.fromJson(response, MineUserEntity.MineUserInfo::class.java)

To allow DMARC checks for SPF to pass and also be aligned when using sendmail, make sure you are setting the envelope sender address (-f or -r parameter) to something that matches the domain in the From: header address.

With PHP:

Using PHP's built-in mail() function without setting the 5th paramater will cause DMARC SPF checks to be unaligned if not done correctly. By default, sendmail will send the email with the webserver's user as the RFC5321.MailFrom / Return Path header.

For example, say you are hosting your website domain.com on the host.com web server. If you do not set the additional parameters parameter:

mail($to,$subject,$message,$headers); // Wrong way

The email recipient will receive an email with the following mail headers:

Return-Path: <[email protected]>
From: <[email protected]>

Even though this passes SPF checks, it will be unaligned (since domain.com and host.com do not match), which means that DMARC SPF check will fail as unaligned.

Instead, you must pass the envelope sender address to sendmail by including the 5th parameter in the PHP mail() function, for example:

mail($to,$subject,$message,$headers, '-r [email protected]'); // Right way

In this case, the email recipient will receive an email with the following mail headers:

Return-Path: <[email protected]>
From: <[email protected]>

Since both of these headers contain addresses from domain.com, SPF will pass and also be aligned, which means that DMARC will also pass the SPF check.

For those who came here looking for a way to download a blob url video / audio, this answer worked for me. In short, you would need to find an *.m3u8 file on the desired web page through Chrome -> Network tab and paste it into a VLC player.

Another guide shows you how to save a stream with the VLC Player.

1.this is my answer for your problem.

.ModalCarrot::before {
content:'';
background: url('blackCarrot.png'); /*url of image*/
height: 16px; /*height of image*/
width: 33px;  /*width of image*/
position: absolute;
}

Maybe this is a bit redundant, but no one appeared to have mentioned this as a solution.

As a beginner in SQL I find that when using a BEGIN and END SSMS usually adds a squiggly line with incorrect syntax near 'END' to END, simply because there's no content in between yet. If you're just setting up BEGIN and END to get started and add the actual query later, then simply add a bogus PRINT statement so SSMS stops bothering you.

For example:

IF (1=1)
BEGIN
  PRINT 'BOGUS'
END

The following will indeed set you on the wrong track, thinking you made a syntax error which in this case just means you still need to add content in between BEGIN and END:

IF (1=1)
BEGIN
END

Create Function

function toggleFullScreen() {

            if ((document.fullScreenElement && document.fullScreenElement !== null) ||
                    (!document.mozFullScreen && !document.webkitIsFullScreen)) {
             $scope.topMenuData.showSmall = true;
                if (document.documentElement.requestFullScreen) {
                    document.documentElement.requestFullScreen();
                } else if (document.documentElement.mozRequestFullScreen) {
                    document.documentElement.mozRequestFullScreen();
                } else if (document.documentElement.webkitRequestFullScreen) {
                    document.documentElement.webkitRequestFullScreen(Element.ALLOW_KEYBOARD_INPUT);
                }
            } else {

                  $scope.topMenuData.showSmall = false;
                if (document.cancelFullScreen) {
                    document.cancelFullScreen();
                } else if (document.mozCancelFullScreen) {
                    document.mozCancelFullScreen();
                } else if (document.webkitCancelFullScreen) {
                    document.webkitCancelFullScreen();
                }
            }
        }

In Html Put Code like

<ul class="unstyled-list fg-white">

            <li class="place-right" data-ng-if="!topMenuData.showSmall" data-ng-click="toggleFullScreen()">Full Screen</li>
            <li class="place-right" data-ng-if="topMenuData.showSmall" data-ng-click="toggleFullScreen()">Back</li>
        </ul>

I think the size of the object matters as well. In one of my projects, we had declared and initialized a large two dimensional array that was making the application throw an out-of-memory exception. We moved the declaration out of the loop instead and cleared the array at the start of every iteration.

You can use the && symbol between commands to execute the second command only if the first succeeds. More info here http://commandwindows.com/command1.htm

How about this?

node-compress
A streaming compression / gzip module for node.js
To install, ensure that you have libz installed, and run:
node-waf configure
node-waf build
This will put the compress.node binary module in build/default.

This worked for me,

Step 1: Click on + New Repository> Clone from URL

Step 2: In Source URL provide URL followed by your user name,

Example:

• GitLab Repo URL : http://git.zaid-labs.info/zaid/iosapp.git
• GitLab User Name : zaid.pathan

So final URL should be http://[email protected]/zaid/iosapp.git

Note: zaid.pathan@ added before git.

Step 3: Enjoy cloning :).

Answer by the user 'onlyblank' is correct. A small addition to that- You can set more than 1 default values if you want.

Instead of passing on id to the setValue(), pass an array. Example:

var $select = $("#my_input").selectize();
var selectize = $select[0].selectize;
var yourDefaultIds = [1,2]; # find the ids using search as shown by the user onlyblank
selectize.setValue(defaultValueIds);

Are you running a 64 bit system with the database running 32 bit but the console running 64 bit? There are no MS Access drivers that run 64 bit and would report an error identical to the one your reported.

Your list:

List<MyCustomObject> myCustomObjectList;

Your JSONArray:

// Don't need to loop through it. JSONArray constructor do it for you.
new JSONArray(myCustomObjectList)

Your response:

return new JSONObject().put("yourCustomKey", new JSONArray(myCustomObjectList));

Your post/put http body request would be like this:

    {
        "yourCustomKey: [
           {
               "myCustomObjectProperty": 1
           },
           {
               "myCustomObjectProperty": 2
           }
        ]
    }

Make sure that "Enable 32 - Bit Applications" is set to false for the app pool.

Use the backslash before db on the header and you can use it then typically as you wrote it before.

Here is the example:

Use \DB;

Then inside your controller class you can use as you did before, like that ie :

$item = DB::table('items')->get();

You can use RelativeSource to find the parent element, like this -

Binding="{Binding Path=DataContext.CurveSpeedMustBeSpecified, 
RelativeSource={RelativeSource AncestorType={x:Type local:YourParentElementType}}}"

See this SO question for more details about RelativeSource.
