In EclipseLink to get the SQL for a specific Query at runtime you can use the DatabaseQuery API:

Query query = em.createNamedQuery("findMe"); 
Session session = em.unwrap(JpaEntityManager.class).getActiveSession(); 
DatabaseQuery databaseQuery = ((EJBQueryImpl)query).getDatabaseQuery(); 
databaseQuery.prepareCall(session, new DatabaseRecord());

String sqlString = databaseQuery.getSQLString();

This SQL will contain ? for parameters. To get the SQL translated with the arguments you need a DatabaseRecord with the parameter values.

DatabaseRecord recordWithValues= new DatabaseRecord();
recordWithValues.add(new DatabaseField("param1"), "someValue");

String sqlStringWithArgs = 
         databaseQuery.getTranslatedSQLString(session, recordWithValues);

Instead of catching the error, wouldn't it be possible to test in or before the myplotfunction() function first if the error will occur (i.e. if the breaks are unique) and only plot it for those cases where it won't appear?!

Or you could use

show tables where Tables_in_{insert_db_name}='tablename';

$var = preg_replace( "/return=[^&]+/", "", $var ); 
$var = preg_replace( "/&{2,}/", "&", $var );

Second line will just replace && to &

A summary.lm object stores these values in a matrix called 'coefficients'. So the value you are after can be accessed with:

a2Pval <- summary(mg)$coefficients[2, 4]

Or, more generally/readably, coef(summary(mg))["a2","Pr(>|t|)"]. See here for why this method is preferred.

In addition to other replies. If you allow html in options you can pass jQuery object to content, and it will be appended to popover's content with all events and bindings. Here is the logic from source code:

• if you pass a function it will be called to unwrap content data
• if html is not allowed content data will be applied as text
• if html allowed and content data is string it will be applied as html
• otherwise content data will be appended to popover's content container

$("#popover-button").popover({
    content: $("#popover-content"),
    html: true,
    title: "Popover title"
});

Since jQuery 1.6, you can use .is. Below is the answer from over a year ago...

var a = $('#foo');
var b = a;


if (a.is(b)) {
    // the same object!
}

If you want to see if two variables are actually the same object, eg:

var a = $('#foo');
var b = a;

...then you can check their unique IDs. Every time you create a new jQuery object it gets an id.

if ($.data(a) == $.data(b)) {
    // the same object!
}

Though, the same could be achieved with a simple a === b, the above might at least show the next developer exactly what you're testing for.

In any case, that's probably not what you're after. If you wanted to check if two different jQuery objects contain the same set of elements, the you could use this:

$.fn.equals = function(compareTo) {
  if (!compareTo || this.length != compareTo.length) {
    return false;
  }
  for (var i = 0; i < this.length; ++i) {
    if (this[i] !== compareTo[i]) {
      return false;
    }
  }
  return true;
};

_Source

var a = $('p');
var b = $('p');
if (a.equals(b)) {
    // same set
}

Eric Niebler is working on a range-proposal and some of the examples show how to remove certain elements. Removing 8. Does create a new vector.

#include <iostream>
#include <range/v3/all.hpp>

int main(int argc, char const *argv[])
{
    std::vector<int> vi{2,4,6,8,10};
    for (auto& i : vi) {
        std::cout << i << std::endl;
    }
    std::cout << "-----" << std::endl;
    std::vector<int> vim = vi | ranges::view::remove_if([](int i){return i == 8;});
    for (auto& i : vim) {
        std::cout << i << std::endl;
    }
    return 0;
}

outputs

#include "stdafx.h"

    cin >> n;
    int *a = new int[n];
    int *b = new int[n];
    for (i = 0; i < n; i++)
    {
        cout << "a[" << i << "]= ";
        cin >> a[i];
    }
    for (i = 0; i < n; i++)
    {
        b[i] = a[n - 1 - i];
    }
    for (i = 0; i < n; i++)
    {
        cout << b[i];
    }
}

Use something like this -

SELECT DISTINCT COL_NAME FROM myTable WHERE UPPER(COL_NAME) LIKE UPPER('%PriceOrder%')

or

SELECT DISTINCT COL_NAME FROM myTable WHERE LOWER(COL_NAME) LIKE LOWER('%PriceOrder%')

Example 1:

funct("z", function (x) { return x; });

function funct(a, foo){
    foo(a) // this will return a
}

Example 2:

function foodemo(value){
    return 'hello '+value;
}

function funct(a, foo){
    alert(foo(a));
}

//call funct    
funct('world!',foodemo); //=> 'hello world!'

look at this

In my case i was returning string value from my api eg: "35" and in my HTML i was using

       <mat-select placeholder="State*" formControlName="states" [(ngModel)]="selectedState" (ngModelChange)="getDistricts()">
            <mat-option *ngFor="let state of formInputs.states" [value]="state.stateId">
              {{ state.stateName }}
            </mat-option>
          </mat-select>

Like others mentioned in the comment value will only accept integer values i guess. So what I did is I converted my string value to integer in my component class like below

          var x = user.state;
          var y: number = +x;

and then assigned it like

  this.EditProfileForm.get('states').setValue(y);

Now the correct values is getting setting by default.

I ran into this problem in the same situation, and I wrote up a detailed answer to a related question on stack overflow explaining how to more easily modify the system's cacerts using a GUI tool. I think it's a little bit better than using a one-off keystore for a specific project or modifying the settings for maven (which may cause trouble down the road).

I assume you have proper xml encoding and matching with Schema.

If you still get this error, check code that unmarshalls the xml and input type you have used. Because XML documents declare their own encoding, it is preferable to create a StreamSource object from an InputStream instead of from a Reader, so that XML processor can correctly handle the declared encoding [Ref Book: Java in A Nutshell ]

Hope this helps!

For me there was no default constructor defined for the POJOs I was trying to use. creating default constructor fixed it.

public class TeamCode {

    @Expose
    private String value;

    public String getValue() {
        return value;
    }

    **public TeamCode() {
    }**

    public TeamCode(String value) {
        this.value = value;
    }

    @Override
    public String toString() {
        return "TeamCode{" +
                "value='" + value + '\'' +
                '}';
    }

    public void setValue(String value) {
        this.value = value;
    }

}

Add the column and update all rows in the DataTable, for example:

DataTable tbl = new DataTable();
tbl.Columns.Add(new DataColumn("ID", typeof(Int32)));
tbl.Columns.Add(new DataColumn("Name", typeof(string)));
for (Int32 i = 1; i <= 10; i++) {
    DataRow row = tbl.NewRow();
    row["ID"] = i;
    row["Name"] = i + ". row";
    tbl.Rows.Add(row);
}
DataColumn newCol = new DataColumn("NewColumn", typeof(string));
newCol.AllowDBNull = true;
tbl.Columns.Add(newCol);
foreach (DataRow row in tbl.Rows) {
    row["NewColumn"] = "You DropDownList value";
}
//if you don't want to allow null-values'
newCol.AllowDBNull = false;

I had the same problem in iOS, using the onChangeText event to update the value of the text typed by the user I was not being able to update the value of the TextInput, so the user would still see the non numeric characters that he typed.

This was because, when a non numeric character was pressed the state would not change since this.setState would be using the same number (the number that remained after removing the non numeric characters) and then the TextInput would not re render.

The only way I found to solve this was to use the keyPress event which happens before the onChangeText event, and in it, use setState to change the value of the state to another, completely different, forcing the re render when the onChangeText event was called. Not very happy with this but it worked.

In MySql, you can get 10 rows starting from row 20 using:

SELECT * FROM Reflow  
WHERE ReflowProcessID = somenumber
ORDER BY ID DESC
LIMIT 10 OFFSET 20 --Equivalent to LIMIT 20, 10

From What is Unicode:

Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one.

......

Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language.

So when a computer represents a string, it finds characters stored in the computer of the string through their unique Unicode number and these figures are stored in memory. But you can't directly write the string to disk or transmit the string on network through their unique Unicode number because these figures are just simple decimal number. You should encode the string to byte string, such as UTF-8. UTF-8 is a character encoding capable of encoding all possible characters and it stores characters as bytes (it looks like this). So the encoded string can be used everywhere because UTF-8 is nearly supported everywhere. When you open a text file encoded in UTF-8 from other systems, your computer will decode it and display characters in it through their unique Unicode number. When a browser receive string data encoded UTF-8 from network, it will decode the data to string (assume the browser in UTF-8 encoding) and display the string.

In python3, you can transform string and byte string to each other:

>>> print('??'.encode('utf-8'))
b'\xe4\xb8\xad\xe6\x96\x87'
>>> print(b'\xe4\xb8\xad\xe6\x96\x87'.decode('utf-8'))
?? 

In a word, string is for displaying to humans to read on a computer and byte string is for storing to disk and data transmission.

You could try giving an ID to the form, in order to get ahold of it, and then call form.submit() from a Javascript call.

Reverting a merge commit has been exhaustively covered in other questions. When you do a fast-forward merge, the second one you describe, you can use git reset to get back to the previous state:

git reset --hard <commit_before_merge>

You can find the <commit_before_merge> with git reflog, git log, or, if you're feeling the moxy (and haven't done anything else): git reset --hard HEAD@{1}

Generate a number in the range from 100000 to 999999.

// pseudo code
int n = 100000 + random_float() * 900000;

For more details see the documentation for Random

Late reply for future reference. What was working for me was enabling it by nuget and then adding custom headers into web.config.

There is no way to get the memory address of a value in Python 2.7 in general. In Jython or PyPy, the implementation doesn't even know your value's address (and there's not even a guarantee that it will stay in the same place—e.g., the garbage collector is allowed to move it around if it wants).

However, if you only care about CPython, id is already returning the address. If the only issue is how to format that integer in a certain way… it's the same as formatting any integer:

>>> hex(33)
0x21
>>> '{:#010x}'.format(33) # 32-bit
0x00000021
>>> '{:#018x}'.format(33) # 64-bit
0x0000000000000021

… and so on.

However, there's almost never a good reason for this. If you actually need the address of an object, it's presumably to pass it to ctypes or similar, in which case you should use ctypes.addressof or similar.

You could also use the below code to redirect to the main page (home):

{ path: '', redirectTo: 'home', pathMatch: 'full'}

After specifying your redirect as above, you can redirect the other pages, for example:

{ path: 'add-new-registration', component: AddNewRegistrationComponent},
{ path: 'view-registration', component: ViewRegistrationComponent},
{ path: 'home', component: HomeComponent}

For what it's worth, you can reset to default the value of a config entry with npm config delete <key> (or npm config rm <key>, but the usage of npm config rm is not mentioned in npm help config).

Example:

# set registry value
npm config set registry "https://skimdb.npmjs.com/registry"
# revert change back to default
npm config delete registry

If you are developing a command line application, you can also use Console.ReadLine() at the end of your code to wait for the 'Enter' keypress before closing the console window so that you can read your output. However, both the Trace and Debug answers posted above are better options.

• STEP 1: Disable KeepAlive

• STEP 3: Limiting the number of service points

First of all, it's actually not accurate to say that

x % 2 == x & 1

Simple counterexample: x = -1. In many languages, including Java, -1 % 2 == -1. That is, % is not necessarily the traditional mathematical definition of modulo. Java calls it the "remainder operator", for example.

With regards to bitwise optimization, only modulo powers of two can "easily" be done in bitwise arithmetics. Generally speaking, only modulo powers of base b can "easily" be done with base b representation of numbers.

In base 10, for example, for non-negative N, N mod 10^k is just taking the least significant k digits.

@ allows a value defined on the directive attribute to be passed to the directive's isolate scope. The value could be a simple string value (myattr="hello") or it could be an AngularJS interpolated string with embedded expressions (myattr="my_{{helloText}}"). Think of it as "one-way" communication from the parent scope into the child directive. John Lindquist has a series of short screencasts explaining each of these. Screencast on @ is here: https://egghead.io/lessons/angularjs-isolate-scope-attribute-binding

& allows the directive's isolate scope to pass values into the parent scope for evaluation in the expression defined in the attribute. Note that the directive attribute is implicitly an expression and does not use double curly brace expression syntax. This one is tougher to explain in text. Screencast on & is here: https://egghead.io/lessons/angularjs-isolate-scope-expression-binding

= sets up a two-way binding expression between the directive's isolate scope and the parent scope. Changes in the child scope are propagated to the parent and vice-versa. Think of = as a combination of @ and &. Screencast on = is here: https://egghead.io/lessons/angularjs-isolate-scope-two-way-binding

And finally here is a screencast that shows all three used together in a single view: https://egghead.io/lessons/angularjs-isolate-scope-review

1. Temporarily rename existing xampp folder
2. Install xampp 1.7.7 into xampp folder name
3. Folder containing just installed 1.7.7 distribution rename to different name and previously existing xampp folder rename back just to xampp.
4. In xampp folder rename php and apache folders to different names (I propose php_prev and apache_prev) so you can after switch back to them by renaming them back.
5. Copy apache and php folders from folder with xampp 1.7.7 into xampp directory

6. In xampp directory comment line apache/conf/httpd.conf:458

   #Include "conf/extra/httpd-perl.conf"

7. In xampp directory do next replaces in files:

Yes, underscores may be used anywhere in an identifier. I believe the rules are: any of a-z, A-Z, _ in the first character and those +0-9 for the following characters.

Underscore prefixes are common in C code -- a single underscore means "private", and double underscores are usually reserved for use by the compiler.

See the end of this post for how to do this in WAMPServer 3

For WampServer 2.5 and previous versions

WAMPServer is designed to be a single seat developers tool. Apache is therefore configure by default to only allow access from the PC running the server i.e. localhost or 127.0.0.1 or ::1

But as it is a full version of Apache all you need is a little knowledge of the server you are using.

The simple ( hammer to crack a nut ) way is to use the 'Put Online' wampmanager menu option.

left click wampmanager icon -> Put Online

This however tells Apache it can accept connections from any ip address in the universe. That's not a problem as long as you have not port forwarded port 80 on your router, or never ever will attempt to in the future.

The more sensible way is to edit the httpd.conf file ( again using the wampmanager menu's ) and change the Apache access security manually.

left click wampmanager icon -> Apache -> httpd.conf

This launches the httpd.conf file in notepad.

Look for this section of this file

<Directory "d:/wamp/www">
    #
    # Possible values for the Options directive are "None", "All",
    # or any combination of:
    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
    #
    # Note that "MultiViews" must be named *explicitly* --- "Options All"
    # doesn't give it to you.
    #
    # The Options directive is both complicated and important.  Please see
    # http://httpd.apache.org/docs/2.4/mod/core.html#options
    # for more information.
    #
    Options Indexes FollowSymLinks

    #
    # AllowOverride controls what directives may be placed in .htaccess files.
    # It can be "All", "None", or any combination of the keywords:
    #   AllowOverride FileInfo AuthConfig Limit
    #
    AllowOverride All

    #
    # Controls who can get stuff from this server.
    #
#    Require all granted
#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost
</Directory>

Now assuming your local network subnet uses the address range 192.168.0.?

Add this line after Allow from localhost

Allow from 192.168.0

This will tell Apache that it is allowed to be accessed from any ip address on that subnet. Of course you will need to check that your router is set to use the 192.168.0 range.

This is simply done by entering this command from a command window ipconfig and looking at the line labeled IPv4 Address. you then use the first 3 sections of the address you see in there.

For example if yours looked like this:-

IPv4 Address. . . . . . . . . . . : 192.168.2.11

You would use

Allow from 192.168.2

UPDATE for Apache 2.4 users

Of course if you are using Apache 2.4 the syntax for this has changed.

You should replace ALL of this section :

Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from ::1
Allow from localhost

With this, using the new Apache 2.4 syntax

Require local
Require ip 192.168.0

You should not just add this into httpd.conf it must be a replace.

For WAMPServer 3 and above

In WAMPServer 3 there is a Virtual Host defined by default. Therefore the above suggestions do not work. You no longer need to make ANY amendments to the httpd.conf file. You should leave it exactly as you find it.

Instead, leave the server OFFLINE as this funtionality is defunct and no longer works, which is why the Online/Offline menu has become optional and turned off by default.

Now you should edit the \wamp\bin\apache\apache{version}\conf\extra\httpd-vhosts.conf file. In WAMPServer3.0.6 and above there is actually a menu that will open this file in your editor

left click wampmanager -> Apache -> httpd-vhost.conf

just like the one that has always existsed that edits your httpd.conf file.

It should look like this if you have not added any of your own Virtual Hosts

#
# Virtual Hosts
#

<VirtualHost *:80>
    ServerName localhost
    DocumentRoot c:/wamp/www
    <Directory  "c:/wamp/www/">
        Options +Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require local
    </Directory>
</VirtualHost>

Now simply change the Require parameter to suite your needs EG

If you want to allow access from anywhere replace Require local with

Require all granted

If you want to be more specific and secure and only allow ip addresses within your subnet add access rights like this to allow any PC in your subnet

Require local
Require ip 192.168.1

Or to be even more specific

Require local
Require ip 192.168.1.100
Require ip 192.168.1.101

Background for the solution

As stated in the mongoose documentation and in the answer by Benjamin, the method Model.count() is deprecated. Instead of using count(), the alternatives are the following:

Model.countDocuments(filterObject, callback)

Counts how many documents match the filter in a collection. Passing an empty object {} as filter executes a full collection scan. If the collection is large, the following method might be used.

Model.estimatedDocumentCount()

This model method estimates the number of documents in the MongoDB collection. This method is faster than the previous countDocuments(), because it uses collection metadata instead of going through the entire collection. However, as the method name suggests, and depending on db configuration, the result is an estimate as the metadata might not reflect the actual count of documents in a collection at the method execution moment.

Both methods return a mongoose query object, which can be executed in one of the following two ways. Use .exec() if you want to execute a query at a later time.

The solution

Option 1: Pass a callback function

For example, count all documents in a collection using .countDocuments():

someModel.countDocuments({}, function(err, docCount) {
    if (err) { return handleError(err) } //handle possible errors
    console.log(docCount)
    //and do some other fancy stuff
})

Or, count all documents in a collection having a certain name using .countDocuments():

someModel.countDocuments({ name: 'Snow' }, function(err, docCount) {
    //see other example
}

Option 2: Use .then()

A mongoose query has .then() so it’s “thenable”. This is for a convenience and query itself is not a promise.

For example, count all documents in a collection using .estimatedDocumentCount():

someModel
    .estimatedDocumentCount()
    .then(docCount => {
        console.log(docCount)
        //and do one super neat trick
    })
    .catch(err => {
        //handle possible errors
    })

Option 3: Use async/await

When using async/await approach, the recommended way is to use it with .exec() as it provides better stack traces.

const docCount = await someModel.countDocuments({}).exec();

Learning by stackoverflowing,

The best answer in my opinion:

$num = count(glob("/exact/path/to/files/" . "*"));
echo $num;

• It doesnt counts . and ..
• Its a one liner
• Im proud of it

I just went through this. If you want to manually move your Eclipse installation you need to find and edit relative references in the following files.

Relative to Eclipse install dir:

• configuration/org.eclipse.equinox.source/source.info
• configuration/org.eclipse.equinox.simpleconfigurator/bundles.info
• configuration/config.ini
• eclipse.ini

For me in all these files there was a ../ reference to a .p2 folder in my home directory. Found them all using a simple grep:

grep '../../../../' * -R

Then just hit it with sed or manually go change it. In my case I moved it up one folder so easy fix:

grep -rl '../../../../' * -R | xargs sed -i 's/..\/..\/..\/..\//..\/..\/..\//g'

Now Eclipse runs fine again.

I implemented it in the following way. I wanted a generic MakeRequest method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type. I create a Dictionary<string, string> object to house the content to be submitted, and then set the HttpRequestMessage Content property with it:

Generic method to call the API:

    private static T MakeRequest<T>(string httpMethod, string route, Dictionary<string, string> postParams = null)
    {
        using (var client = new HttpClient())
        {
            HttpRequestMessage requestMessage = new HttpRequestMessage(new HttpMethod(httpMethod), $"{_apiBaseUri}/{route}");

            if (postParams != null)
                requestMessage.Content = new FormUrlEncodedContent(postParams);   // This is where your content gets added to the request body


            HttpResponseMessage response = client.SendAsync(requestMessage).Result;

            string apiResponse = response.Content.ReadAsStringAsync().Result;
            try
            {
                // Attempt to deserialise the reponse to the desired type, otherwise throw an expetion with the response from the api.
                if (apiResponse != "")
                    return JsonConvert.DeserializeObject<T>(apiResponse);
                else
                    throw new Exception();
            }
            catch (Exception ex)
            {
                throw new Exception($"An error ocurred while calling the API. It responded with the following message: {response.StatusCode} {response.ReasonPhrase}");
            }
        }
    }

Call the method:

    public static CardInformation ValidateCard(string cardNumber, string country = "CAN")
    { 
        // Here you create your parameters to be added to the request content
        var postParams = new Dictionary<string, string> { { "cardNumber", cardNumber }, { "country", country } };
        // make a POST request to the "cards" endpoint and pass in the parameters
        return MakeRequest<CardInformation>("POST", "cards", postParams);
    }

Good quote taken from a blog

The DOM component is "garbage collected", as is the JScript component, which means that if you create an object within either component, and then lose track of that object, it will eventually be cleaned up.

For example:

function makeABigObject() {
var bigArray = new Array(20000);
}

When you call that function, the JScript component creates an object (named bigArray) that is accessible within the function. As soon as the function returns, though, you "lose track" of bigArray because there's no way to refer to it anymore. Well, the JScript component realizes that you've lost track of it, and so bigArray is cleaned up--its memory is reclaimed. The same sort of thing works in the DOM component. If you say document.createElement('div'), or something similar, then the DOM component creates an object for you. Once you lose track of that object somehow, the DOM component will clean up the related.

You need to use javascript for this.

<form id="form1" action="showMessage.jsp" method="post">
    <a href="javascript:;" onclick="document.getElementById('form1').submit();"><%=n%></a>
    <input type="hidden" name="mess" value=<%=n%>/>
</form>

Let me quote this:

Hibernate created a new language named Hibernate Query Language (HQL), the syntax is quite similar to database SQL language. The main difference between is HQL uses class name instead of table name, and property names instead of column name.

As far as I can see you are using the table name.

So it should be like this:

Query query = session.createQuery("from Employee");

SQL> alter session set "_ORACLE_SCRIPT"=true;  
SQL> create user sec_admin identified by "Chutinhbk123@!";

You can also perform Implicit Type Conversions with template literals. Example:

let fruits = ["mango","orange","pineapple","papaya"];

console.log(`My favourite fruits are ${fruits}`);
// My favourite fruits are mango,orange,pineapple,papaya

You have Integer#to_s(base) and String#to_i(base) available to you.

Integer#to_s(base) converts a decimal number to a string representing the number in the base specified:

9.to_s(2) #=> "1001"

while the reverse is obtained with String#to_i(base):

"1001".to_i(2) #=> 9

This method worked in my case.

video=getElementsByTagName('video');
function removeControls(video){
  video.removeAttribute('controls');
}
window.onload=removeControls(video);

I like to use presence, inspired from Ruby on Rails:

$.fn.presence = function () {
    return this.length !== 0 && this;
}

Your example becomes:

alert($('#notAnElement').presence() || "No object found");

I find it superior to the proposed $.fn.exists because you can still use boolean operators or if, but the truthy result is more useful. Another example:

$ul = $elem.find('ul').presence() || $('<ul class="foo">').appendTo($elem)
$ul.append('...')

Days until Christmas:

>>> import datetime
>>> today = datetime.date.today()
>>> someday = datetime.date(2008, 12, 25)
>>> diff = someday - today
>>> diff.days
86

More arithmetic here.

Subclass is to Class as Java is to Programming Language.

From the code that you have provided, not knowing the language that you are programming in. The variable capital is null. When you are trying to read the property length, the system cant as it is trying to deference a null variable. You need to define capital.

That header file is not part of the C++ standard, is therefore non-portable, and should be avoided.

Moreover, even if there were some catch-all header in the standard, you would want to avoid it in lieu of specific headers, since the compiler has to actually read in and parse every included header (including recursively included headers) every single time that translation unit is compiled.

I believe this is what you're looking for:

Convert Decimal Numbers to Text showing only the non-zero decimals

Especially this line might be helpful:

StringVar text     :=  Totext ( {Your.NumberField} , 6 , ""  )  ;

The first parameter is the decimal to be converted, the second parameter is the number of decimal places and the third parameter is the separator for thousands/millions etc.

To access the entity body of a POST or PUT request (or any other HTTP method):

$entityBody = file_get_contents('php://input');

Also, the STDIN constant is an already-open stream to php://input, so you can alternatively do:

$entityBody = stream_get_contents(STDIN);

From the PHP manual entry on I/O streams^docs:

php://input is a read-only stream that allows you to read raw data from the request body. In the case of POST requests, it is preferable to use php://input instead of $HTTP_RAW_POST_DATA as it does not depend on special php.ini directives. Moreover, for those cases where $HTTP_RAW_POST_DATA is not populated by default, it is a potentially less memory intensive alternative to activating always_populate_raw_post_data. php://input is not available with enctype="multipart/form-data".

Specifically you'll want to note that the php://input stream, regardless of how you access it in a web SAPI, is not seekable. This means that it can only be read once. If you're working in an environment where large HTTP entity bodies are routinely uploaded you may wish to maintain the input in its stream form (rather than buffering it like the first example above).

To maintain the stream resource something like this can be helpful:

<?php

function detectRequestBody() {
    $rawInput = fopen('php://input', 'r');
    $tempStream = fopen('php://temp', 'r+');
    stream_copy_to_stream($rawInput, $tempStream);
    rewind($tempStream);

    return $tempStream;
}

php://temp allows you to manage memory consumption because it will transparently switch to filesystem storage after a certain amount of data is stored (2M by default). This size can be manipulated in the php.ini file or by appending /maxmemory:NN, where NN is the maximum amount of data to keep in memory before using a temporary file, in bytes.

Of course, unless you have a really good reason for seeking on the input stream, you shouldn't need this functionality in a web application. Reading the HTTP request entity body once is usually enough -- don't keep clients waiting all day while your app figures out what to do.

Note that php://input is not available for requests specifying a Content-Type: multipart/form-data header (enctype="multipart/form-data" in HTML forms). This results from PHP already having parsed the form data into the $_POST superglobal.

Try the command

sudo mysql_secure_installation

press enter and assign a new password for root in mysql/mariadb.

If you get an error like

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock'

enable the service with

service mysql start

now if you re-enter with

mysql -u root -p

if you follow the problem enter with sudo su and mysql -u root -p now apply permissions to root

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' IDENTIFIED BY '<password>';

this fixed my problem in MariaDB.

Good luck

Take below reference to convert a JSON into POJO and vice-versa

Let's suppose your JSON schema looks like:

{
  "type":"object",
  "properties": {
    "dataOne": {
      "type": "string"
    },
    "dataTwo": {
      "type": "integer"
    },
    "dataThree": {
      "type": "boolean"
    }
  }
}

Then to covert into POJO, your need to decleare some classes as explained in below style:

==================================
package ;
public class DataOne
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class DataTwo
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class DataThree
{
    private String type;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
}

==================================
package ;
public class Properties
{
    private DataOne dataOne;

    private DataTwo dataTwo;

    private DataThree dataThree;

    public void setDataOne(DataOne dataOne){
        this.dataOne = dataOne;
    }
    public DataOne getDataOne(){
        return this.dataOne;
    }
    public void setDataTwo(DataTwo dataTwo){
        this.dataTwo = dataTwo;
    }
    public DataTwo getDataTwo(){
        return this.dataTwo;
    }
    public void setDataThree(DataThree dataThree){
        this.dataThree = dataThree;
    }
    public DataThree getDataThree(){
        return this.dataThree;
    }
}

==================================
package ;
public class Root
{
    private String type;

    private Properties properties;

    public void setType(String type){
        this.type = type;
    }
    public String getType(){
        return this.type;
    }
    public void setProperties(Properties properties){
        this.properties = properties;
    }
    public Properties getProperties(){
        return this.properties;
    }
}

One more option, not exactly what you asked, but can be useful:

Go to Settings -> Editor -> File and code templates -> Includes tab (on the right). There is a template header for the new files, you can use the username here:

/**
 * @author myname
 */

For system username use:

/**
 * @author ${USER}
 */

There is a middle way. If you want a HTML control but you need to access it server side you can simply add the runat="server" attribute:

<a runat="server" Id="lnkBack">Back</a>

You can then alter the href server side using Attributes

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
       lnkBack.Attributes.Add("href", url);
    }
}

resulting in:

<a id="ctl00_ctl00_mainContentPlaceHolder_contentPlaceHolder_lnkBack" 
      href="url.aspx">Back</a>

in my case, adding -lboost_system was not enough, it still could not find it in my custom build environment. I had to use the advice at Get rid of "gcc - /usr/bin/ld: warning lib not found" and change my ./configure command to:

./configure CXXFLAGS="-I$HOME/include" LDFLAGS="-L$HOME/lib -Wl,-rpath-link,$HOME/lib" --with-boost-libdir=$HOME/lib --prefix=$HOME

for more details see Boost 1.51 : "error: could not link against boost_thread !"

when you need to call derived class destructor from base class. you need to declare virtual base class destructor in base class.

If I'm not mistaken this is usually handled via a timeout.

You will need to create an instance of a new window like so.

var window2 = new Window2();

Once you have the instance you can use the Show() or ShowDialog() method depending on what you want to do.

window2.Show();

or

var result = window2.ShowDialog();

ShowDialog() will return a Nullable<bool> if you need that.

I believe +%s is seconds since epoch. It's timezone invariant.

fout = "/your/outfile/here.txt"
fo = open(fout, "w")

for k, v in yourDictionary.items():
    fo.write(str(k) + ' >>> '+ str(v) + '\n\n')

fo.close()

Here's an ugly solution for you:

var date = new Date(new Date().setDate(new Date().getDate() - 30));

You can use microtime and calculate the difference:

$time_pre = microtime(true);
exec(...);
$time_post = microtime(true);
$exec_time = $time_post - $time_pre;

Here's the PHP docs for microtime: http://php.net/manual/en/function.microtime.php

Thank you all for this thread! My colleague and I just discovered that the default_value property is a Constant, not a Variable.

In other React forms I've built, the default value for a Select was preset in an associated Context. So the first time the Select was rendered, default_value was set to the correct value.

But in my latest React form (a small modal), I'm passing the values for the form as props and then using a useEffect to populate the associated Context. So the FIRST time the Select is rendered, default_value is set to null. Then when the Context is populated and the Select is supposed to be re-rendered, default_value cannot be changed and thus the initial default value is not set.

The solution was ultimately simple: Use the value property instead. But figuring out why default_value didn't work like it did with my other forms took some time.

I'm posting this to help others in the community.

This is a simple task. You can follow the following steps.

1. Create a folder in your solution and name it Reports.
2. Add an ASP.Net web form and name it ReportView.aspx

3. Create a Class ReportData and add it to the Reports folder. Add the following code to the Class.

   public class ReportData  
   {  
       public ReportData()  
       {  
           this.ReportParameters = new List<Parameter>();  
           this.DataParameters = new List<Parameter>();  
       }
   
       public bool IsLocal { get; set; }
       public string ReportName { get; set; }
       public List<Parameter> ReportParameters { get; set; }
       public List<Parameter> DataParameters { get; set; }
   }
   
   public class Parameter  
   {  
       public string ParameterName { get; set; }  
       public string Value { get; set; }  
   }
   

4. Add another Class and name it ReportBasePage.cs. Add the following code in this Class.

   public class ReportBasePage : System.Web.UI.Page
   {
       protected ReportData ReportDataObj { get; set; }
   
       protected override void OnInit(EventArgs e)
       {
           base.OnInit(e);
           if (HttpContext.Current != null)
               if (HttpContext.Current.Session["ReportData"] != null)
               {
                   ReportDataObj = HttpContext.Current.Session["ReportData"] as ReportData;
                   return;
               }
           ReportDataObj = new ReportData();
           CaptureRouteData(Page.Request);
       }
   
   
       private void CaptureRouteData(HttpRequest request)
       {
           var mode = (request.QueryString["rptmode"] + "").Trim();
           ReportDataObj.IsLocal = mode == "local" ? true : false;
           ReportDataObj.ReportName = request.QueryString["reportname"] + "";
           string dquerystr = request.QueryString["parameters"] + "";
           if (!String.IsNullOrEmpty(dquerystr.Trim()))
           {
               var param1 = dquerystr.Split(',');
               foreach (string pm in param1)
               {
                   var rp = new Parameter();
                   var kd = pm.Split('=');
                   if (kd[0].Substring(0, 2) == "rp")
                   {
                       rp.ParameterName = kd[0].Replace("rp", "");
                       if (kd.Length > 1) rp.Value = kd[1];
                       ReportDataObj.ReportParameters.Add(rp);
                   }
                   else if (kd[0].Substring(0, 2) == "dp")
                   {
                       rp.ParameterName = kd[0].Replace("dp", "");
                       if (kd.Length > 1) rp.Value = kd[1];
                       ReportDataObj.DataParameters.Add(rp);
                   }
               }
           }
       }
   }
   

5. Add ScriptManager to the ReportView.aspx page. Now add a Report Viewer to the page. In report viewer set the property AsyncRendering="false". The code is given below.

       <rsweb:ReportViewer ID="ReportViewerRSFReports" runat="server" AsyncRendering="false"
           Width="1271px" Height="1000px" >
       </rsweb:ReportViewer>
   

6. Add two NameSpace in ReportView.aspx.cs

   using Microsoft.Reporting.WebForms;
   using System.IO;
   

7. Change the System.Web.UI.Page to ReportBasePage. Just replace your code using the following.

   public partial class ReportView : ReportBasePage
   {
       protected void Page_Load(object sender, EventArgs e)
       {
           if (!IsPostBack)
           {
               RenderReportModels(this.ReportDataObj);
           }
       }
   
       private void RenderReportModels(ReportData reportData)
       {
           // This is the Data Access Layer from which a method is called to fill data to the list.
           RASolarERPData dal = new RASolarERPData();
           List<ClosingInventoryValuation> objClosingInventory = new List<ClosingInventoryValuation>();
   
           // Reset report properties.
           ReportViewerRSFReports.Height = Unit.Parse("100%");
           ReportViewerRSFReports.Width = Unit.Parse("100%");
           ReportViewerRSFReports.CssClass = "table";
   
           // Clear out any previous datasources.
           this.ReportViewerRSFReports.LocalReport.DataSources.Clear();
   
           // Set report mode for local processing.
           ReportViewerRSFReports.ProcessingMode = ProcessingMode.Local;
   
           // Validate report source.
           var rptPath = Server.MapPath(@"./Report/" + reportData.ReportName +".rdlc");
   
           //@"E:\RSFERP_SourceCode\RASolarERP\RASolarERP\Reports\Report\" + reportData.ReportName + ".rdlc";
           //Server.MapPath(@"./Report/ClosingInventory.rdlc");
   
           if (!File.Exists(rptPath))
               return;
   
           // Set report path.
           this.ReportViewerRSFReports.LocalReport.ReportPath = rptPath;
   
           // Set report parameters.
           var rpPms = ReportViewerRSFReports.LocalReport.GetParameters();
           foreach (var rpm in rpPms)
           {
               var p = reportData.ReportParameters.SingleOrDefault(o => o.ParameterName.ToLower() == rpm.Name.ToLower());
               if (p != null)
               {
                   ReportParameter rp = new ReportParameter(rpm.Name, p.Value);
                   ReportViewerRSFReports.LocalReport.SetParameters(rp);
               }
           }
   
           //Set data paramater for report SP execution
           objClosingInventory = dal.ClosingInventoryReport(this.ReportDataObj.DataParameters[0].Value);
   
           // Load the dataSource.
           var dsmems = ReportViewerRSFReports.LocalReport.GetDataSourceNames();
           ReportViewerRSFReports.LocalReport.DataSources.Add(new ReportDataSource(dsmems[0], objClosingInventory));
   
           // Refresh the ReportViewer.
           ReportViewerRSFReports.LocalReport.Refresh();
       }
   }
   

8. Add a Folder to the Reports Folder and name it Report. Now add a RDLC report to the Reports/Report folder and name it ClosingInventory.rdlc.

9. Now add a Controller and name it ReportController. In the controller add the following action method.

   public ActionResult ReportViewer()
       {                
           ViewData["reportUrl"] = "../Reports/View/local/ClosingInventory/";
   
           return View();
       }
   

10. Add a view page click on the ReportViewer Controller. Name the view page ReportViewer.cshtml. Add the following code to the view page.

    @using (Html.BeginForm("Login"))
     { 
           @Html.DropDownList("ddlYearMonthFormat", new SelectList(ViewBag.YearMonthFormat, "YearMonthValue",
     "YearMonthName"), new { @class = "DropDown" })
    
    Stock In Transit: @Html.TextBox("txtStockInTransit", "", new { @class = "LogInTextBox" })
    
    <input type="submit" onclick="return ReportValidationCheck();" name="ShowReport"
                     value="Show Report" />
    
    }
    

11. Add an Iframe. Set the property of the Iframe as follows

    frameborder="0"  width="1000"; height="1000"; style="overflow:hidden;"
    scrolling="no"
    

12. Add Following JavaScript to the viewer.

    function ReportValidationCheck() {
    
        var url = $('#hdUrl').val();
        var yearmonth = $('#ddlYearMonthFormat').val();      
        var stockInTransit = $('#txtStockInTransit').val()
    
        if (stockInTransit == "") {
            stockInTransit = 0;
        }
    
        if (yearmonth == "0") {
            alert("Please Select Month Correctly.");
        }
        else {
    
            //url = url + "dpSpYearMonth=" + yearmonth + ",rpYearMonth=" + yearmonth + ",rpStockInTransit=" + stockInTransit;
    
            url = "../Reports/ReportView.aspx?rptmode=local&reportname=ClosingInventory&parameters=dpSpYearMonth=" + yearmonth + ",rpYearMonth=" + yearmonth + ",rpStockInTransit=" + stockInTransit;
    
            var myframe = document.getElementById("ifrmReportViewer");
            if (myframe !== null) {
                if (myframe.src) {
                    myframe.src = url;
                }
                else if (myframe.contentWindow !== null && myframe.contentWindow.location !== null) {
                    myframe.contentWindow.location = url;
                }
                else { myframe.setAttribute('src', url); }
            }
        }
    
        return false;
    }
    

13. Web.config file add the following key to the appSettings section

    add key="UnobtrusiveJavaScriptEnabled" value="true"
    

14. In system.web handlers Section add the following key

    add verb="*" path="Reserved.ReportViewerWebControl.axd" type = "Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
    

15. Change your data source to your own. This solution is very simple and I think every one will enjoy it.

You can use the pseudo-selector :checkbox with a call to jQuery's is function:

$('#myinput').is(':checkbox')

To add to Paul's answer, I found that to ultimately recover space, I have to push HEAD to a clean repository and that trims down the size of the .git/objects/pack directory.

i.e.

$ mkdir ...ABC.git
$ cd ...ABC.git
$ git init --bare

After the gc prune, also do:

$ git push ...ABC.git HEAD

Then you can do

$ git clone ...ABC.git

and the size of ABC/.git is reduced

Actually, some of the time consuming steps (e.g. git gc) aren't needed with the push to clean repository, i.e.:

$ git clone --no-hardlinks /XYZ /ABC
$ git filter-branch --subdirectory-filter ABC HEAD
$ git reset --hard
$ git push ...ABC.git HEAD

Extending on the answers, this is what worked for me, maybe someone will find it useful.

Html

<form method="post" action="/url" id="editMeta">
   <textarea class="form-control" onkeypress="submitOnEnter(event)"></textarea>
</form>

Js

function submitOnEnter(e) {
  if (e.which == 13) {
    document.getElementById("editMeta").submit()
  }
}

How about something like this.

Test the live example: http://jsfiddle.net/6hBZU/1/

It assumes that the string will always end with the extension:

function openFile(file) {
    var extension = file.substr( (file.lastIndexOf('.') +1) );
    switch(extension) {
        case 'jpg':
        case 'png':
        case 'gif':
            alert('was jpg png gif');  // There's was a typo in the example where
        break;                         // the alert ended with pdf instead of gif.
        case 'zip':
        case 'rar':
            alert('was zip rar');
        break;
        case 'pdf':
            alert('was pdf');
        break;
        default:
            alert('who knows');
    }
};

openFile("somestring.png");

EDIT: I mistakenly deleted part of the string in openFile("somestring.png");. Corrected. Had it in the Live Example, though.

I have stumbled upon this problem for one hour. After an hour, I tried debugging and this helped:

$('.list').on('click', 'span', (e) => {
  $(e.target).parent().remove();
});

HTML:

<ul class="list">
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
  <li class="task">some text<span>X</span></li>
</ul>

try this, this works for me, I forgot where I found it, somewhere in stack overflow, i'm not here to explained it why it doesn't work, but this is the answer :).

    final ListView AturIsiPulsaDataIsiPulsa = (ListView) findViewById(R.id.listAturIsiPulsaDataIsiPulsa);
    AturIsiPulsaDataIsiPulsa.setOnTouchListener(new ListView.OnTouchListener() 
    {
        @Override
        public boolean onTouch(View v, MotionEvent event) 
        {
            int action = event.getAction();
            switch (action) 
            {
                case MotionEvent.ACTION_DOWN:
                // Disallow ScrollView to intercept touch events.
                v.getParent().requestDisallowInterceptTouchEvent(true);
                break;

                case MotionEvent.ACTION_UP:
                // Allow ScrollView to intercept touch events.
                v.getParent().requestDisallowInterceptTouchEvent(false);
                break;
            }

            // Handle ListView touch events.
            v.onTouchEvent(event);
            return true;
        }
    });
    AturIsiPulsaDataIsiPulsa.setClickable(true);
    AturIsiPulsaDataIsiPulsa.setAdapter(AturIsiPulsaDataIsiPulsaAdapter);

EDIT !, I finally found out where I got the code. here ! : ListView inside ScrollView is not scrolling on Android

It's not difficult and actually documented:

import youtube_dl

ydl = youtube_dl.YoutubeDL({'outtmpl': '%(id)s.%(ext)s'})

with ydl:
    result = ydl.extract_info(
        'http://www.youtube.com/watch?v=BaW_jenozKc',
        download=False # We just want to extract the info
    )

if 'entries' in result:
    # Can be a playlist or a list of videos
    video = result['entries'][0]
else:
    # Just a video
    video = result

print(video)
video_url = video['url']
print(video_url)

The one exception worth noting is that while you can't delete apps, the folks over at Google Play Developer Support are able to on their end if the app is both unpublished and has 0 lifetime installs. So if your app has 0 lifetime installs, you might be in luck.

First you will need unpublish the app and wait 24 hours (to allow global stats to update and ensure that no last-minute installs happened). Assuming no last-minute installs happen over those 24 hours, you can contact Google Play Developer Support and check to see if they can delete it.

Please note that their requirement for 0 installs is a hard requirement. No exceptions can be made (not even if you installed the app yourself for testing purposes).

if (position ==0) {
    if (rYes.isChecked()) {
        Toast.makeText(SportActivity.this, "yes ur answer is right", Toast.LENGTH_LONG).show();
    } else if (rNo.isChecked()) {
        Toast.makeText(SportActivity.this, "no.ur answer is wrong", Toast.LENGTH_LONG).show();
    }
}

This code is supposed to select both check boxes.
Is there a problem with it?

I find it odd that (Apache) StringUtils wasn't covered here yet.

you can remove all newlines (or any other occurences of a substring for that matter) from a string using the .replace method

StringUtils.replace(myString, "\n", "");

This line will replace all newlines with the empty string.

because newline is technically a character you can optionally use the .replaceChars method that will replace characters

StringUtils.replaceChars(myString, '\n', '');

You can add an extra exit command after the return statement/command so that it works for both, executing the script from the command line and sourcing from the terminal.

Example exit code in the script:

   if [ $# -lt 2 ]; then
     echo "Needs at least two arguments"
     return 1 2>/dev/null
     exit 1
   fi

The line with the exit command will not be called when you source the script after the return command.

When you execute the script, return command gives an error. So, we suppress the error message by forwarding it to /dev/null.

This has been answered by numerous ways but what I came up with was the simplest and easiest for me with Bootstrap 3 and font awesome. I just did

$('a.toggler').on('click', function () {$('i', this).toggleClass('fa-caret-up');});

This just toggles the CSS class of the icon I want to show. I add the class toggler to the item I want to apply this to. This can be added onto any item you want to toggle an icon.

It is a good approach. I use it myself as well. I would only suggest to override onCreate to set the singleton instead of using a constructor.

And since you mentioned SQLiteOpenHelper: In onCreate () you can open the database as well.

Personally I think the documentation got it wrong in saying that There is normally no need to subclass Application. I think the opposite is true: You should always subclass Application.

I think using visual block mode is a better and more versatile method for dealing with this type of thing. Here's an example:

This is the First line.  
This is the second.  
The third.

To insert " Hello world." (space + clipboard) at the end of each of these lines:

• On a character in the first line, press Ctrl-V (or Ctrl-Q if Ctrl-V is paste).
• Press jj to extend the visual block over three lines.
• Press $ to extend the visual block to the end of each line. Press A then space then type Hello world. + then Esc.

The result is:

This is the First line. Hello world.  
This is the second. Hello world.  
The third. Hello world.  

(example from Vim.Wikia.com)

In C ^ is the bitwise XOR:

0101 ^ 1100 = 1001 // in binary

There's no operator for power, you'll need to use pow function from math.h (or some other similar function):

result = pow( a, i );

Laravel v5.6.12 (2018-03-14) added fromSub() and fromRaw() methods to query builder (#23476).

The accepted answer is correct but can be simplified into:

DB::query()->fromSub(function ($query) {
    $query->from('abc')->groupBy('col1');
}, 'a')->count();

The above snippet produces the following SQL:

select count(*) as aggregate from (select * from `abc` group by `col1`) as `a`

that syntax is now deprecated, you will get this error:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 14: Expected a stage @ line 14, column 9.
       parallel firstTask: {
       ^

WorkflowScript: 14: Stage does not have a name @ line 14, column 9.
       parallel secondTask: {
       ^

2 errors

You should do something like:

stage("Parallel") {
    steps {
        parallel (
            "firstTask" : {
                //do some stuff
            },
            "secondTask" : {
                // Do some other stuff in parallel
            }
        )
    }
}

Just to add the use of node here, to distribute jobs across multiple build servers/ VMs:

pipeline {
  stages {
    stage("Work 1"){
     steps{
      parallel ( "Build common Library":   
            {
              node('<Label>'){
                  /// your stuff
                  }
            },

        "Build Utilities" : {
            node('<Label>'){
               /// your stuff
              }
           }
         )
    }
}

All VMs should be labelled as to use as a pool.

Though @Test(expected = MyException.class) and the ExpectedException rule are very good choices, there are some instances where the JUnit3-style exception catching is still the best way to go:

@Test public void yourTest() {
  try {
    systemUnderTest.doStuff();
    fail("MyException expected.");
  } catch (MyException expected) {

    // Though the ExpectedException rule lets you write matchers about
    // exceptions, it is sometimes useful to inspect the object directly.

    assertEquals(1301, expected.getMyErrorCode());
  }

  // In both @Test(expected=...) and ExpectedException code, the
  // exception-throwing line will be the last executed line, because Java will
  // still traverse the call stack until it reaches a try block--which will be
  // inside the JUnit framework in those cases. The only way to prevent this
  // behavior is to use your own try block.

  // This is especially useful to test the state of the system after the
  // exception is caught.

  assertTrue(systemUnderTest.isInErrorState());
}

Another library that claims to help here is catch-exception; however, as of May 2014, the project appears to be in maintenance mode (obsoleted by Java 8), and much like Mockito catch-exception can only manipulate non-final methods.

Working on the same idea as above , but generalizing a bit . Since the backspace should work fine on the input elements , but should not work if the focus is a paragraph or something , since it is there where the page tends to go back to the previous page in history .

$('html').on('keydown' , function(event) {

        if(! $(event.target).is('input')) {
            console.log(event.which);
           //event.preventDefault();
           if(event.which == 8) {
            //  alert('backspace pressed');
            return false;
         }
        }
});

returning false => both event.preventDefault and event.stopPropagation are in effect .

I resolved this problem by deleting the registry key under

hkey_current_user\software\Microsoft\VSCommon\12.0\clientservices\tokenstorage\visualstudio\ideuser

var img = new Image();

$(img).load(function(){

  $('.container').append($(this));

}).attr({

  src: someRemoteImage

}).error(function(){
  //do something if image cannot load
});

This provides an answer for people who arrive at this Question that may want to link an editor other than vim.

The linked resource, by Github,is likely to be kept up to date, when editors are updated, even if answers on SO (including this one) are not.

Associating Text Editors with git

Github's post shows exactly what to type in to your command line for various editors, including the options/flags specific to each editor for it to work best with git.

Notepad++:
git config --global core.editor "'C:/Program Files (x86)/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"

Sublime Text:
git config --global core.editor "'c:/Program Files/sublime text 3/subl.exe' -w"

Atom:
git config --global core.editor "atom --wait"

The commands above assume your editor has been installed in the default directory for a windows machine.

The commands basically add the text between double-quotes to .gitconfig in your home directory.
On a windows machine home is likely to be C:\Users\your-user-name, where your-user-name is your login name.
From the command line, you can reach this directory by typing in cd ~.

for example, a command above would be add the following line under the [core] section like so:
[core] editor = 'C:/Program Files/sublime text 3/subl.exe' -w

If you have a different editor, just replace with the path to your editor, using either method above. (and hope no flags are needed for optimal usage.)

dict.copy() is a shallow copy function for dictionary
id is built-in function that gives you the address of variable

First you need to understand "why is this particular problem is happening?"

In [1]: my_dict = {'a': [1, 2, 3], 'b': [4, 5, 6]}

In [2]: my_copy = my_dict.copy()

In [3]: id(my_dict)
Out[3]: 140190444167808

In [4]: id(my_copy)
Out[4]: 140190444170328

In [5]: id(my_copy['a'])
Out[5]: 140190444024104

In [6]: id(my_dict['a'])
Out[6]: 140190444024104

The address of the list present in both the dicts for key 'a' is pointing to same location.
Therefore when you change value of the list in my_dict, the list in my_copy changes as well.

Solution for data structure mentioned in the question:

In [7]: my_copy = {key: value[:] for key, value in my_dict.items()}

In [8]: id(my_copy['a'])
Out[8]: 140190444024176

Or you can use deepcopy as mentioned above.

You can use the auto_now and auto_now_add options for updated_at and created_at respectively.

class MyModel(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

Example of using a function() in bash:

# file.sh: a sample shell script to demonstrate the concept of Bash shell functions
# define usage function
usage(){
    echo "Usage: $0 filename"
    exit 1
}

# define is_file_exists function
# $f -> store argument passed to the script
is_file_exists(){
    local f="$1"
    [[ -f "$f" ]] && return 0 || return 1
}
# invoke  usage
# call usage() function if filename not supplied
[[ $# -eq 0 ]] && usage

# Invoke is_file_exits
if ( is_file_exists "$1" )
then
 echo "File found: $1"
else
 echo "File not found: $1"
fi

I wanted to open the Bluetooth Menu in the Settings Application and the above path (prefs:root=General&path=Bluetooth) didn't work for me. What ended up working for me was

UIApplication.sharedApplication().openURL(NSURL(string:"prefs:root=Bluetooth")!)

Make sure you have the prefs URL Scheme defined first.

If Folder getting from other, and host file is already generated on ProjectName\.vs\config folder, then it conflicts with a new one and gets this error.
So delete host file from ProjectName\.vs\config and restart project once again. It was worked for me

I was getting an error while installation that not able to link node and /usr/local/include is not writable

Below solution worked for me :- First create the include folder, note that this requires sudo privileges

cd /usr/local

sudo mkdir include

sudo chown -R $(whoami) $(brew --prefix)/*

brew link node

To do this in the fewest lines I would suggest using the built-in DIRECTORY_SEPARATOR constant along with explode(delimiter, string) to separate the path into parts and then simply pluck off the last element in the provided array.

Example:

$path = 'F:\Program Files\SSH Communications Security\SSH SecureShell\Output.map'

//Get filename from path
$pathArr = explode(DIRECTORY_SEPARATOR, $path);
$filename = end($pathArr);

echo $filename;
>> 'Output.map'

Try this script

<script language="JavaScript">
function fullScreen(theURL) {
window.open(theURL, '', 'fullscreen=yes, scrollbars=auto' );
}
</script>

For calling from script use this code,

window.fullScreen('fullscreen.jsp');

or with hyperlink use this

<a href="javascript:void(0);" onclick="fullScreen('fullscreen.jsp');"> 
Open in Full Screen Window</a>

As of iOS 5.0 Apple provides the NSJSONSerialization class "to convert JSON to Foundation objects and convert Foundation objects to JSON". No external frameworks to incorporate and according to benchmarks its performance is quite good, significantly better than SBJSON.

You should know that it is not possible to directly run a DDL statement like you do for DML from a PL/SQL block because PL/SQL does not support late binding directly it only support compile time binding which is fine for DML. hence to overcome this type of problem oracle has provided a dynamic SQL approach which can be used to execute the DDL statements.The dynamic sql approach is about parsing and binding of sql string at the runtime. Also you should rememder that DDL statements are by default auto commit hence you should be careful about any of the DDL statement using the dynamic SQL approach incase if you have some DML (which needs to be commited explicitly using TCL) before executing the DDL in the stored proc/function.

You can use any of the following dynamic sql approach to execute a DDL statement from a pl/sql block.

1) Execute immediate

2) DBMS_SQL package

3) DBMS_UTILITY.EXEC_DDL_STATEMENT (parse_string IN VARCHAR2);

Hope this answers your question with explanation.

I believe for this typical case, i.e. to run something with a fixed interval, Timer is more appropriate. Here is a simple example:

myTimer = new Timer();
myTimer.schedule(new TimerTask() {          
@Override
public void run() {
    // If you want to modify a view in your Activity
    MyActivity.this.runOnUiThread(new Runnable()
        public void run(){
            tv.append("Hello World");
        });
    }
}, 1000, 1000); // initial delay 1 second, interval 1 second

Using Timer has few advantages:

• Initial delay and the interval can be easily specified in the schedule function arguments
• The timer can be stopped by simply calling myTimer.cancel()
• If you want to have only one thread running, remember to call myTimer.cancel() before scheduling a new one (if myTimer is not null)

myHash.each{|item|..} is returning you array object for item iterative variable like the following :--

[:company_name, "MyCompany"]
[:street, "Mainstreet"]
[:postcode, "1234"]
[:city, "MyCity"]
[:free_seats, "3"]

You should do this:--

def format
  output = Hash.new
  myHash.each do |k, v|
    output[k] = cleanup(v)
  end
  output
end

To compare between latest commit of current branch and a tag:

git log --pretty=oneline HEAD...tag

First use pkill or kill -9 <pid> to kill the process.

Then use following userdel command to delete user,

userdel -f cafe_fixer

According to userdel man page:

-f, --force

This option forces the removal of the user account, even if the user is still logged in. It also forces userdel to remove the user's home directory and mail spool, even if another user uses the same home directory or if the mail spool is not owned by the specified user. If USERGROUPS_ENAB is defined to yes in /etc/login.defs and if a group exists with the same name as the deleted user, then this group will be removed, even if it is still the primary group of another user.

Edit 1: (by @Ajedi32)

Note: This option (i.e. --force) is dangerous and may leave your system in an inconsistent state.

Edit 2: (by @socketpair)

In spite of the description about some files, this key allows removing the user while it is in use. Don't forget to chdir / before, because this command will also remove home directory.

You have mentioned Wrong id

alert(document.getElementById("name").value);

if you want to use name attribute then

alert(document.getElementsByName("username")[0].value);

Updates:

input type="text" id="name" name="username"  

id is different from name

Create a scope property called selectedIndex, and an itemClicked function:

function MyController ($scope) {
  $scope.collection = ["Item 1", "Item 2"];

  $scope.selectedIndex = 0; // Whatever the default selected index is, use -1 for no selection

  $scope.itemClicked = function ($index) {
    $scope.selectedIndex = $index;
  };
}

Then my template would look something like this:

<div>
      <span ng-repeat="item in collection"
             ng-class="{ 'selected-class-name': $index == selectedIndex }"
             ng-click="itemClicked($index)"> {{ item }} </span>
</div>

Just for reference $index is a magic variable available within ng-repeat directives.

You can use this same sample within a directive and template as well.

When I used policy before I set the default authentication scheme into it as well. I had modified the DefaultPolicy so it was slightly different. However the same should work for add policy as well.

                                {
                                    CookieAuthenticationDefaults.AuthenticationScheme
                                }
            });
        });

Do take into consideration that by Default AuthenticationSchemes property uses a read only list. I think it would be better to implement that instead of List as well.

Performance

Today 2020.12.04 I perform tests on MacOs HighSierra 10.13.6 on Chrome v86, Safari v13.1.2 and Firefox v83 for chosen solutions.

Results

For all browsers

• in-place solution based on length (B) is fastest for small arrays, and in Firefox for big too and for Chrome and Safari is fast
• in-place solution based on push (A) is fastest for big arrays on Chrome and Safari, and fast for Firefox and small arrays
• in-place solution C is slow for big arrays and medium fast for small
• non-in-place solutions D and E are slow for big arrays
• non-in-place solutions E,F and D(on Firefox) are slow for small arrays

Details

I perform 2 tests cases:

• for small array with 10 elements - you can run it HERE
• for big array with 1M elements - you can run it HERE

Below snippet presents differences between solutions A, B, C, D, E, F

Yes you can convert it back. You can try:

date("Y-m-d H:i:s", 1388516401);

The logic behind this conversion from date to an integer is explained in strtotime in PHP:

The function expects to be given a string containing an English date format and will try to parse that format into a Unix timestamp (the number of seconds since January 1 1970 00:00:00 UTC), relative to the timestamp given in now, or the current time if now is not supplied.

For example, strtotime("1970-01-01 00:00:00") gives you 0 and strtotime("1970-01-01 00:00:01") gives you 1.

This means that if you are printing strtotime("2014-01-01 00:00:01") which will give you output 1388516401, so the date 2014-01-01 00:00:01 is 1,388,516,401 seconds after January 1 1970 00:00:00 UTC.

This should do it

At the end of your for() loop, you can use the savefig() function instead of plt.show() and set the name, dpi and format of your figure.

E.g. 1000 dpi and eps format are quite a good quality, and if you want to save every picture at folder ./ with names 'Sample1.eps', 'Sample2.eps', etc. you can just add the following code:

for fname in glob("./*.txt"):
    # Your previous code goes here
    [...]

    plt.savefig("./{}.eps".format(fname), bbox_inches='tight', format='eps', dpi=1000)

In Angular 7, the (ngModelChange)="eventHandler()" will fire before the value bound to [(ngModel)]="value" is changed while the (change)="eventHandler()" will fire after the value bound to [(ngModel)]="value" is changed.

My scenario is little different, but the intent is same i would like to know when the parent window hosting my user control is closing/closed as The view(i.e my usercontrol) should invoke the presenters oncloseView to execute some functionality and perform clean up. ( well we are implementing a MVP pattern on a WPF PRISM application).

I just figured that in the Loaded event of the usercontrol, i can hook up my ParentWindowClosing method to the Parent windows Closing event. This way my Usercontrol can be aware when the Parent window is being closed and act accordingly!

According to Ruby Doc instance_methods

Returns an array containing the names of the public and protected instance methods in the receiver. For a module, these are the public and protected methods; for a class, they are the instance (not singleton) methods. If the optional parameter is false, the methods of any ancestors are not included. I am taking the official documentation example.

module A
  def method1()  
    puts "method1 say hi"
  end
end
class B
  include A #mixin
  def method2()  
     puts "method2 say hi"
  end
end
class C < B #inheritance
  def method3() 
     puts "method3 say hi"
  end
end

Let's see the output.

A.instance_methods(false)
  => [:method1]

A.instance_methods
  => [:method1]
B.instance_methods
 => [:method2, :method1, :nil?, :===, ...# ] # methods inherited from parent class, most important :method1 is also visible because we mix module A in class B

B.instance_methods(false)
  => [:method2]
C.instance_methods
  => [:method3, :method2, :method1, :nil?, :===, ...#] # same as above
C.instance_methods(false)
 => [:method3]

Here is other example:

import numpy as np
import pandas as pd

""" This just creates a list of touples, and each element of the touple is an array"""
a = [ (np.random.randint(1,10,10), np.array([0,1,2,3,4,5,6,7,8,9]))  for i in 
range(0,10) ]

""" Panda DataFrame will allocate each of the arrays , contained as a touple 
element , as column"""
df = pd.DataFrame(data =a,columns=['random_num','sequential_num'])

The secret in general is to allocate the data in the form a = [ (array_11, array_12,...,array_1n),...,(array_m1,array_m2,...,array_mn) ] and panda DataFrame will order the data in n columns of arrays. Of course , arrays of arrays could be used instead of touples, in that case the form would be : a = [ [array_11, array_12,...,array_1n],...,[array_m1,array_m2,...,array_mn] ]

This is the output if you print(df) from the code above:

                       random_num                  sequential_num
0  [7, 9, 2, 2, 5, 3, 5, 3, 1, 4]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
1  [8, 7, 9, 8, 1, 2, 2, 6, 6, 3]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
2  [3, 4, 1, 2, 2, 1, 4, 2, 6, 1]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
3  [3, 1, 1, 1, 6, 2, 8, 6, 7, 9]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
4  [4, 2, 8, 5, 4, 1, 2, 2, 3, 3]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
5  [3, 2, 7, 4, 1, 5, 1, 4, 6, 3]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
6  [5, 7, 3, 9, 7, 8, 4, 1, 3, 1]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
7  [7, 4, 7, 6, 2, 6, 3, 2, 5, 6]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
8  [3, 1, 6, 3, 2, 1, 5, 2, 2, 9]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
9  [7, 2, 3, 9, 5, 5, 8, 6, 9, 8]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Other variation of the example above:

b = [ (i,"text",[14, 5,], np.array([0,1,2,3,4,5,6,7,8,9]))  for i in 
range(0,10) ]
df = pd.DataFrame(data=b,columns=['Number','Text','2Elemnt_array','10Element_array'])

Output of df:

   Number  Text 2Elemnt_array                 10Element_array
0       0  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
1       1  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
2       2  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
3       3  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
4       4  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
5       5  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
6       6  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
7       7  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
8       8  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
9       9  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

If you want to add other columns of arrays, then:

df['3Element_array']=[([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3]),([1,2,3])]

The final output of df will be:

   Number  Text 2Elemnt_array                 10Element_array 3Element_array
0       0  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]
1       1  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]
2       2  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]
3       3  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]
4       4  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]
5       5  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]
6       6  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]
7       7  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]
8       8  text       [14, 5]  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]      [1, 2, 3]

Most of the answers given seem to assume that all the classes we are looking to inherit from are defined by us.

But what if one of the classes is not defined by us, i.e. we cannot change what one of those classes inherits from and therefore cannot make use of the accepted answer, what happens then?

Well the answer depends on if we have at least one of the classes having been defined by us. i.e. there exists a class A among the list of classes we would like to inherit from, where A is created by us.

In addition to the already accepted answer, I propose 3 more instances of this multiple inheritance problem and possible solutions to each.

Inheritance type 1

Ok say you want a class C to extend classes, A and B, where B is a class defined somewhere else, but A is defined by us. What we can do with this is to turn A into an interface then, class C can implement A while extending B.

class A {}
class B {} // Some external class
class C {}

Turns into

interface A {}
class AImpl implements A {}
class B {} // Some external class
class C extends B implements A

Inheritance type 2

Now say you have more than two classes to inherit from, well the same idea still holds - all but one of the classes has to be defined by us. So say we want class A to inherit from the following classes, B, C, ... X where X is a class which is external to us, i.e. defined somewhere else. We apply the same idea of turning all the other classes but the last into an interface then we can have:

interface B {}
class BImpl implements B {}
interface C {}
class CImpl implements C {}
...
class X {}
class A extends X implements B, C, ...

Inheritance type 3

Finally, there is also the case where you have just a bunch of classes to inherit from, but none of them are defined by you. This is a bit trickier, but it is doable by making use of delegation. Delegation allows a class A to pretend to be some other class B but any calls on A to some public method defined in B, actually delegates that call to an object of type B and the result is returned. This makes class A what I would call a Fat class

How does this help?

Well it's simple. You create an interface which specifies the public methods within the external classes which you would like to make use of, as well as methods within the new class you are creating, then you have your new class implement that interface. That may have sounded confusing, so let me explain better.

Initially we have the following external classes B, C, D, ..., X, and we want our new class A to inherit from all those classes.

class B {
    public void foo() {}
}

class C {
    public void bar() {}
}

class D {
    public void fooFoo() {}
}

...

class X {
    public String fooBar() {}
}

Next we create an interface A which exposes the public methods that were previously in class A as well as the public methods from the above classes

interface A {
    void doSomething(); // previously defined in A
    String fooBar(); // from class X
    void fooFoo(); // from class D
    void bar(); // from class C
    void foo(); // from class B
}

Finally, we create a class AImpl which implements the interface A.

class AImpl implements A {
    // It needs instances of the other classes, so those should be
    // part of the constructor
    public AImpl(B b, C c, D d, X x) {}
    ... // define the methods within the interface
}

And there you have it! This is sort of pseudo-inheritance because an object of type A is not a strict descendant of any of the external classes we started with but rather exposes an interface which defines the same methods as in those classes.

You might ask, why we didn't just create a class that defines the methods we would like to make use of, rather than defining an interface. i.e. why didn't we just have a class A which contains the public methods from the classes we would like to inherit from? This is done in order to reduce coupling. We don't want to have classes that use A to have to depend too much on class A (because classes tend to change a lot), but rather to rely on the promise given within the interface A.

Android 4.2 Jelly Bean (API 17) puts the text paddingLeft from the buttonDrawable (ints right edge). It also works for RTL mode.

Before 4.2 paddingLeft was ignoring the buttonDrawable - it was taken from the left edge of the CompoundButton view.

You can solve it via XML - set paddingLeft to buttonDrawable.width + requiredSpace on older androids. Set it to requiredSpace only on API 17 up. For example use dimension resources and override in values-v17 resource folder.

The change was introduced via android.widget.CompoundButton.getCompoundPaddingLeft();

After reading all comments. this was my resolution:
I had to "Add" it again than commit:

$ git commit -i -m support.html "doit once for all" [master 18ea92e] support.html

Implement an interface to call your function in your method
interface IMyInterface
{
 void MyinterfaceMethod();
}

IMyInterface MyObj = obj as IMyInterface;
if ( MyObj != null)
{
MyMethod(IMyInterface MyObj );
}

        function yourfunctionName() {
            var yourFileName = $("#yourinputfieldis").val();

            var yourFileExtension = yourFileName .replace(/^.*\./, '');
            switch (yourFileExtension ) {
                case 'pdf':
                case 'jpg':
                case 'doc':
                    $("#formId").submit();// your condition what you want to do
                    break;
                default:
                    alert('your File extension is wrong.');
                    this.value = '';
            }    
        }

In .NET Core 2.0 MVC app / Microsoft.AspNetCore.All v2.0.0, you can have environmental specific startup class as described by @vaindil but I don't like that approach.

You can also inject IHostingEnvironment into StartUp constructor. You don't need to store the environment variable in Program class.

public class Startup
{
    private readonly IHostingEnvironment _currentEnvironment;
    public IConfiguration Configuration { get; private set; }

    public Startup(IConfiguration configuration, IHostingEnvironment env)
    {
        _currentEnvironment = env;
        Configuration = configuration;
    }

    public void ConfigureServices(IServiceCollection services)
    {
        ......

        services.AddMvc(config =>
        {
            // Requiring authenticated users on the site globally
            var policy = new AuthorizationPolicyBuilder()
                .RequireAuthenticatedUser()
                .Build();
            config.Filters.Add(new AuthorizeFilter(policy));

            // Validate anti-forgery token globally
            config.Filters.Add(new AutoValidateAntiforgeryTokenAttribute());

            // If it's Production, enable HTTPS
            if (_currentEnvironment.IsProduction())      // <------
            {
                config.Filters.Add(new RequireHttpsAttribute());
            }            
        });

        ......
    }
}

sudo apt-get install mysql-client-core-5.5

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

git branch -d [branch name] for local delete

git branch -D [branch name] also for local delete but forces it

I deleted folder app/build and the problem was resolved in my case.

You have to be careful, server responses in the range of 4xx and 5xx throw a WebException. You need to catch it, and then get status code from a WebException object:

try
{
    wResp = (HttpWebResponse)wReq.GetResponse();
    wRespStatusCode = wResp.StatusCode;
}
catch (WebException we)
{
    wRespStatusCode = ((HttpWebResponse)we.Response).StatusCode;
}

barplot(data)

barplot(data, yaxp=c(0, max(data), 5))

yaxp=c(minY-axis, maxY-axis, Interval)

If you use ng-model, you don't want to also use ng-checked. Instead just initialize the model variable to true. Normally you would do this in a controller that is managing your page (add one). In your fiddle I just did the initialization in an ng-init attribute for demonstration purposes.

http://jsfiddle.net/UTULc/

<div ng-app="">
  Send to Office: <input type="checkbox" ng-model="checked" ng-init="checked=true"><br/>
  <select id="transferTo" ng-disabled="checked">
    <option>Tech1</option>
    <option>Tech2</option>
  </select>
</div>

See the following snippet, is this what you want?

body {
    background: silver;
    padding: 0 10px;
}

#content:after {
    height: 10px;
    display: block;
    width: 100px;
    background: #808080;
    border-right: 1px white;
    content: '';
}

#footer:before {
    display: block;
    content: '';
    background: silver;
    height: 10px;
    margin-top: -20px;
    margin-left: 101px;
}

#content {
    background: white;
}


#footer {
    padding-top: 10px;
    background: #404040;

Faced with the same issue, supporting older devices via the deprecated camera API and needing the new Camera2 API for both current devices and moving into the future; I ran into the same issues -- and have not found a 3rd party library that bridges the 2 APIs, likely because they are very different, I turned to basic OOP principals.

The 2 APIs are markedly different making interchanging them problematic for client objects expecting the interfaces presented in the old API. The new API has different objects with different methods, built using a different architecture. Got love for Google, but ragnabbit! that's frustrating.

So I created an interface focussing on only the camera functionality my app needs, and created a simple wrapper for both APIs that implements that interface. That way my camera activity doesn't have to care about which platform its running on...

I also set up a Singleton to manage the API(s); instancing the older API's wrapper with my interface for older Android OS devices, and the new API's wrapper class for newer devices using the new API. The singleton has typical code to get the API level and then instances the correct object.

The same interface is used by both wrapper classes, so it doesn't matter if the App runs on Jellybean or Marshmallow--as long as the interface provides my app with what it needs from either Camera API, using the same method signatures; the camera runs in the App the same way for both newer and older versions of Android.

The Singleton can also do some related things not tied to the APIs--like detecting that there is indeed a camera on the device, and saving to the media library.

I hope the idea helps you out.

The number 0 in {0:X} refers to the position in the list or arguments. In this case 0 means use the first value, which is Blue. Use {1:X} for the second argument (Green), and so on.

colorstring = String.Format("#{0:X}{1:X}{2:X}{3:X}", Blue, Green, Red, Space);

The syntax for the format parameter is described in the documentation:

Format Item Syntax

Each format item takes the following form and consists of the following components:

{ index[,alignment][:formatString]}

The matching braces ("{" and "}") are required.

Index Component

The mandatory index component, also called a parameter specifier, is a number starting from 0 that identifies a corresponding item in the list of objects. That is, the format item whose parameter specifier is 0 formats the first object in the list, the format item whose parameter specifier is 1 formats the second object in the list, and so on.

Multiple format items can refer to the same element in the list of objects by specifying the same parameter specifier. For example, you can format the same numeric value in hexadecimal, scientific, and number format by specifying a composite format string like this: "{0:X} {0:E} {0:N}".

Each format item can refer to any object in the list. For example, if there are three objects, you can format the second, first, and third object by specifying a composite format string like this: "{1} {0} {2}". An object that is not referenced by a format item is ignored. A runtime exception results if a parameter specifier designates an item outside the bounds of the list of objects.

Alignment Component

The optional alignment component is a signed integer indicating the preferred formatted field width. If the value of alignment is less than the length of the formatted string, alignment is ignored and the length of the formatted string is used as the field width. The formatted data in the field is right-aligned if alignment is positive and left-aligned if alignment is negative. If padding is necessary, white space is used. The comma is required if alignment is specified.

Format String Component

The optional formatString component is a format string that is appropriate for the type of object being formatted. Specify a standard or custom numeric format string if the corresponding object is a numeric value, a standard or custom date and time format string if the corresponding object is a DateTime object, or an enumeration format string if the corresponding object is an enumeration value. If formatString is not specified, the general ("G") format specifier for a numeric, date and time, or enumeration type is used. The colon is required if formatString is specified.

Note that in your case you only have the index and the format string. You have not specified (and do not need) an alignment component.

Oracle has two different ways of making views updatable:-

1. The view is "key preserved" with respect to what you are trying to update. This means the primary key of the underlying table is in the view and the row appears only once in the view. This means Oracle can figure out exactly which underlying table row to update OR
2. You write an instead of trigger.

I would stay away from instead-of triggers and get your code to update the underlying tables directly rather than through the view.

I have not found a satisfying answer for this question, i.e how to load edit, run and save. Overwriting either using %%writefile or %save -f doesn't work well if you want to show incremental changes in git. It would look like you delete all the lines in filename.py and add all new lines, even though you just edit 1 line.

Here is the code for it, enjoy!, I picked that up from the dotNetReference type the "using" statement inside the namespace line 106 http://referencesource.microsoft.com/#mscorlib/microsoft/win32/win32native.cs

using System;
using System.Collections.Generic;
namespace UsingStatement
{
    using Typedeffed = System.Int32;
    using TypeDeffed2 = List<string>;
    class Program
    {
        static void Main(string[] args)
        {
        Typedeffed numericVal = 5;
        Console.WriteLine(numericVal++);

        TypeDeffed2 things = new TypeDeffed2 { "whatever"};
        }
    }
}

Try using a single quote instead of double quotes along with -g

Following scenario worked for me

curl -g -d '{"collection":[{"NumberOfParcels":1,"Weight":1,"Length":1,"Width":1,"Height":1}]}" -H "Accept: application/json" -H "Content-Type: application/json" --user [email protected]:123456 -X POST  https://yoururl.com

WITH

curl -g -d "{'collection':[{'NumberOfParcels':1,'Weight':1,'Length':1,'Width':1,'Height':1}]}" -H "Accept: application/json" -H "Content-Type: application/json" --user [email protected]:123456 -X POST  https://yoururl.com

This especially resolved my error curl command error : bad url colon is first character

All that is left is to

git checkout featurex
git merge our-team

This will merge our-team into featurex.

The above assumes you have already committed/stashed your changes in featurex, if that is not the case you will need to do this first.

Based in @TMS answer, I like it because there's no need for subqueries but I think ommiting the 'OR' part will be sufficient and much simpler to understand and read.

SELECT t1.*
FROM lms_attendance AS t1
LEFT JOIN lms_attendance AS t2
  ON t1.user = t2.user 
        AND t1.time < t2.time
WHERE t2.user IS NULL

if you are not interested in rows with null times you can filter them in the WHERE clause:

SELECT t1.*
FROM lms_attendance AS t1
LEFT JOIN lms_attendance AS t2
  ON t1.user = t2.user 
        AND t1.time < t2.time
WHERE t2.user IS NULL and t1.time IS NOT NULL

You're probably just getting a stack overflow here. The array is too big to fit in your program's stack address space.

If you allocate the array on the heap you should be fine, assuming your machine has enough memory.

int* array = new int[1000000];

But remember that this will require you to delete[] the array. A better solution would be to use std::vector<int> and resize it to 1000000 elements.

On Windows, you can also use the Win32 File Namespace prefixed with \\?\ to refer to your local directories:

\\?\C:\my_dir

See this answer for description.

Let me expand a bit on a VonC's very comprehensive answer:

First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.

Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".

Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

HTH

Unfortunately, yes.

void MyParameterizedFunction(String param1, int param2, bool param3=false) {}

could be written in Java 1.5 as:

void MyParameterizedFunction(String param1, int param2, Boolean... params) {
    assert params.length <= 1;
    bool param3 = params.length > 0 ? params[0].booleanValue() : false;
}

But whether or not you should depend on how you feel about the compiler generating a

new Boolean[]{}

for each call.

For multiple defaultable parameters:

void MyParameterizedFunction(String param1, int param2, bool param3=false, int param4=42) {}

could be written in Java 1.5 as:

void MyParameterizedFunction(String param1, int param2, Object... p) {
    int l = p.length;
    assert l <= 2;
    assert l < 1 || Boolean.class.isInstance(p[0]);
    assert l < 2 || Integer.class.isInstance(p[1]);
    bool param3 = l > 0 && p[0] != null ? ((Boolean)p[0]).booleanValue() : false;
    int param4 = l > 1 && p[1] != null ? ((Integer)p[1]).intValue() : 42;
}

This matches C++ syntax, which only allows defaulted parameters at the end of the parameter list.

Beyond syntax, there is a difference where this has run time type checking for passed defaultable parameters and C++ type checks them during compile.

It should be document.getElementById("hidden").style.display = "block"; not document.getElementById["hidden"].style.display = "block";

EDIT due to author edit:

Why are you using a <div> here? Just add an ID to the table element and add a hidden style to it. E.g. <td id="hidden" style="display:none" class="depot_table_left">

Multiply by 2, round, then divide by 2

if you want nearest quarter, multiply by 4, divide by 4, etc

Replace '+' with '000'. For example, 'U+1F600' will become 'U0001F600' and prepend the Unicode code with "\" and print. Example:

>>> print("Learning : ", "\U0001F40D")
Learning :  
>>> 

Check this maybe it will help python unicode emoji

Use git add -A, this will include the deleted files.

Note: use git rm for certain files.

On Linux and BSD you can directly create the socket in non-blocking mode (https://www.man7.org/linux/man-pages/man7/socket.7.html):

int fd = socket(res->ai_family, res->ai_socktype | SOCK_NONBLOCK | SOCK_CLOEXEC, res->ai_protocol);
if (fd == -1) {
    perror("socket");
    return -1;
}

When accepting connections you can use the accept4 function to directly accept new connections in non-blocking mode (https://man7.org/linux/man-pages/man2/accept.2.html):

int fd = accept4(lfd, NULL, 0, SOCK_NONBLOCK | SOCK_CLOEXEC);
if (fd == -1) {
    perror("accept4");
    return -1;
}

I don't know why the accepted answer doesn't mention this.

This is the better way that I use to create submit without loading in a form.

You can use some CSS to stylise the iframe the way you want.

A php result will be loaded into the iframe.

<form method="post" action="test.php" target="view">
  <input type="text" name="anyname" palceholder="Enter your name"/>
  <input type="submit" name="submit" value="submit"/>
  </form>
<iframe name="view" frameborder="0" style="width:100%">
  </iframe>

import * as Rx from 'rxjs/Rx';

We should add the above import to make the blow code to work

Let obs = Rx.Observable
    .interval(1000).take(3);

obs.subscribe(value => console.log('Subscriber: ' + value));

Please note that there is a mistake in the url provided in this answer:

For a PUT mapping request: the url should be as follows:

http://localhost:9200/name_of_index/_mappings/document_type

and NOT

http://localhost:9200/name_of_index/document_type/_mappings

Aligning text in native markdown is not possible. However, you can align the text using inline HTML tags.

<div style="text-align: right"> your-text-here </div>

To justify, replace right with justify in the above.

If Apache was installed using NSIS installer it should have left an uninstaller. You should search inside Apache installation directory for executable named unistaller.exe or something like that. NSIS uninstallers support /S flag by default for silent uninstall. So you can run something like "C:\Program Files\<Apache installation dir here>\uninstaller.exe" /S

From NSIS documentation:

3.2.1 Common Options

/NCRC disables the CRC check, unless CRCCheck force was used in the script. /S runs the installer or uninstaller silently. See section 4.12 for more information. /D sets the default installation directory ($INSTDIR), overriding InstallDir and InstallDirRegKey. It must be the last parameter used in the command line and must not contain any quotes, even if the path contains spaces. Only absolute paths are supported.

To fetch single row

$result = $this->getEntityManager()->getConnection()->fetchAssoc($sql)

To fetch all records

$result = $this->getEntityManager()->getConnection()->fetchAll($sql)

Here you can use sql native query, all will work without any issue.

Best way to do what you want is to add another server block:

server {
        #implemented by default, change if you need different ip or port
        #listen *:80 | *:8000;
        server_name test.com;
        return 301 $scheme://www.test.com$request_uri;
}

And edit your main server block server_name variable as following:

server_name  www.test.com;

Important: New server block is the right way to do this, if is evil. You must use locations and servers instead of if if it's possible. Rewrite is sometimes evil too, so replaced it with return.

There is a change in syntax from Python 2 to Python 3. In Python 2,

print "Hello, World!" 

will work but in Python 3, use parentheses as

print("Hello, World!")

This is equivalent syntax to Scala and near to Java.

It seems you can provide just the local image name, assuming it is in the same folder...

It suffices like:

background-image: url("img1.png")

It really depends on the database server.

For example, SQL Server 2008 supports a FILESTREAM datatype for exactly this situation.

Other than that, if you use a MemoryStream, it has a ToArray() method that will convert to a byte[] - this can be used for populating a varbinary field..

sudo xcodebuild -license

will take care of it with no trouble on the command line. Note that you'll have to manually scroll through the license, and agree to its terms at the end, unless you add "accept" to the command line :

sudo xcodebuild -license accept

Jasmine doesn't have that functionality, but you might be able to hack something together using Object.defineProperty.

You could refactor your code to use a getter function, then spy on the getter.

spyOn(myObj, 'getValueA').andReturn(1);
expect(myObj.getValueA()).toBe(1);

Here is code with AWK. It can be done more simply. But I am not good in AWK.

filename$ ls
abc.a.txt  a.b.c.txt  pp-kk.txt
filename$ find . -type f | awk -F/ '{print $2}' | rev | awk -F"." '{$1="";print}' | rev | awk 'gsub(" ",".") ,sub(".$", "")'
abc.a
a.b.c
pp-kk
filename$ find . -type f | awk -F/ '{print $2}' | awk -F"." '{print $NF}'
txt
txt
txt

UPDATE

Angular offers now the two scope methods $watchGroup (since 1.3) and $watchCollection. Those have been mentioned by @blazemonger and @kargold.

This should work independent of the types and values:

$scope.$watch('[age,name]', function () { ... }, true);

You have to set the third parameter to true in this case.

The string concatenation 'age + name' will fail in a case like this:

<button ng-init="age=42;name='foo'" ng-click="age=4;name='2foo'">click</button>

Before the user clicks the button the watched value would be 42foo (42 + foo) and after the click 42foo (4 + 2foo). So the watch function would not be called. So better use an array expression if you cannot ensure, that such a case will not appear.

PS:

As stated by @reblace in a comment, it is of course possible to access the values:

$scope.$watch('[age,name]', function (newValue, oldValue) {
    var newAge  = newValue[0];
    var newName = newValue[1];
    var oldAge  = oldValue[0];
    var oldName = oldValue[1];
}, true);

Like mentioned before, Math.max() only takes two arguments. It's not exactly compatible with your current syntax but you could try Collections.max().

If you don't like that you can always create your own method for it...

public class test {
    final static int MY_INT1 = 25;
    final static int MY_INT2 = -10;
    final static double MY_DOUBLE1 = 15.5;

    public static void main(String args[]) {
        double maxOfNums = multiMax(MY_INT1, MY_INT2, MY_DOUBLE1);
    }

    public static Object multiMax(Object... values) {
        Object returnValue = null;
        for (Object value : values)
            returnValue = (returnValue != null) ? ((((value instanceof Integer) ? (Integer) value
                    : (value instanceof Double) ? (Double) value
                            : (Float) value) > ((returnValue instanceof Integer) ? (Integer) returnValue
                    : (returnValue instanceof Double) ? (Double) returnValue
                            : (Float) returnValue)) ? value : returnValue)
                    : value;
        return returnValue;
    }
}

This will take any number of mixed numeric arguments (Integer, Double and Float) but the return value is an Object so you would have to cast it to Integer, Double or Float.

It might also be throwing an error since there is no such thing as "MY_DOUBLE2".

Just as a addition. You can find the Catalina Paths in

->RUN->RUN CONFIGURATIONS->APACHE TOMCAT->ARGUMENTS

In the VM Arguments the Paths are listed and changeable

Here's my solution, loads from .json to allow changes without rebuilding

import { Injectable, Inject } from '@angular/core';
import { Http } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import { Location } from '@angular/common';

@Injectable()
export class ConfigService {

    private config: any;

    constructor(private location: Location, private http: Http) {
    }

    async apiUrl(): Promise<string> {
        let conf = await this.getConfig();
        return Promise.resolve(conf.apiUrl);
    }

    private async getConfig(): Promise<any> {
        if (!this.config) {
            this.config = (await this.http.get(this.location.prepareExternalUrl('/assets/config.json')).toPromise()).json();
        }
        return Promise.resolve(this.config);
    }
}

and config.json

{
    "apiUrl": "http://localhost:3000/api"
}

HttpClientFactory

It's important to evaluate the different ways you can create an HttpClient, and part of that is understanding HttpClientFactory.

https://docs.microsoft.com/en-us/dotnet/architecture/microservices/implement-resilient-applications/use-httpclientfactory-to-implement-resilient-http-requests

This is not a direct answer I know - but you're better off starting here than ending up with new HttpClient(...) everywhere.

You can also get this error by prematurely taking PyCharm's advice to annotate a method @staticmethod. Remove the annotation.

Instead of foreach(), use a for() loop with a numeric index.

add this line to your sonar-project.properties file

ex: sonar.exclusions=src/*.java be careful if you want to exclude a folder and inside the folder there is a file you must first exclude the files or add the files one by one for example imagine there is a folder like below:

src/app.java src/controllers/home.java src/services/test.java

you have to do this: sonar.exclusions=src/app.java,src/controllers/*.java,src/services/*.java

It worked for me

Another option is set this value "tcp_keepalives_idle". Check more in documentation https://www.postgresql.org/docs/10/runtime-config-connection.html.

You can use the -d option with mysqldump command

mysqldump -u root -p -d databasename > database.sql

width:1px;
white-space: nowrap;

works fine for me :)

I had these SQL behavior settings enabled on options query execution: ANSI SET IMPLICIT_TRANSACTIONS checked. On execution of your query e.g create, alter table or stored procedure, you have to COMMIT it.

Just type COMMIT and execute it F5

1. start up the command prompt (CMD) with administrator rights.
2. Type c:\windows\microsoft.net\framework\v4.0.30319\installutil.exe [your windows service path to exe]
3. Press return

CSS isn't going to be able to call other elements like that, you'll need to use JavaScript to reach beyond a child or sibling selector.

You could try something like this:

<a>Some Link
<div><img src="/you/image" /></div>
</a>

then...

a>div { display: none; }
a:hover>div { display: block; }

Visitor

Visitor allows one to add new virtual functions to a family of classes without modifying the classes themselves; instead, one creates a visitor class that implements all of the appropriate specializations of the virtual function

Visitor structure:

Use Visitor pattern if:

1. Similar operations have to be performed on objects of different types grouped in a structure
2. You need to execute many distinct and unrelated operations. It separates Operation from objects Structure
3. New operations have to be added without change in object structure
4. Gather related operations into a single class rather than force you to change or derive classes
5. Add functions to class libraries for which you either do not have the source or cannot change the source

Even though Visitor pattern provides flexibility to add new operation without changing the existing code in Object, this flexibility has come with a drawback.

If a new Visitable object has been added, it requires code changes in Visitor & ConcreteVisitor classes. There is a workaround to address this issue : Use reflection, which will have impact on performance.

Code snippet:

import java.util.HashMap;

interface Visitable{
    void accept(Visitor visitor);
}

interface Visitor{
    void logGameStatistics(Chess chess);
    void logGameStatistics(Checkers checkers);
    void logGameStatistics(Ludo ludo);    
}
class GameVisitor implements Visitor{
    public void logGameStatistics(Chess chess){
        System.out.println("Logging Chess statistics: Game Completion duration, number of moves etc..");    
    }
    public void logGameStatistics(Checkers checkers){
        System.out.println("Logging Checkers statistics: Game Completion duration, remaining coins of loser");    
    }
    public void logGameStatistics(Ludo ludo){
        System.out.println("Logging Ludo statistics: Game Completion duration, remaining coins of loser");    
    }
}

abstract class Game{
    // Add game related attributes and methods here
    public Game(){

    }
    public void getNextMove(){};
    public void makeNextMove(){}
    public abstract String getName();
}
class Chess extends Game implements Visitable{
    public String getName(){
        return Chess.class.getName();
    }
    public void accept(Visitor visitor){
        visitor.logGameStatistics(this);
    }
}
class Checkers extends Game implements Visitable{
    public String getName(){
        return Checkers.class.getName();
    }
    public void accept(Visitor visitor){
        visitor.logGameStatistics(this);
    }
}
class Ludo extends Game implements Visitable{
    public String getName(){
        return Ludo.class.getName();
    }
    public void accept(Visitor visitor){
        visitor.logGameStatistics(this);
    }
}

public class VisitorPattern{
    public static void main(String args[]){
        Visitor visitor = new GameVisitor();
        Visitable games[] = { new Chess(),new Checkers(), new Ludo()};
        for (Visitable v : games){
            v.accept(visitor);
        }
    }
}

Explanation:

1. Visitable (Element) is an interface and this interface method has to be added to a set of classes.
2. Visitor is an interface, which contains methods to perform an operation on Visitable elements.
3. GameVisitor is a class, which implements Visitor interface ( ConcreteVisitor).
4. Each Visitable element accept Visitor and invoke a relevant method of Visitor interface.
5. You can treat Game as Element and concrete games like Chess,Checkers and Ludo as ConcreteElements.

In above example, Chess, Checkers and Ludo are three different games ( and Visitable classes). On one fine day, I have encountered with a scenario to log statistics of each game. So without modifying individual class to implement statistics functionality, you can centralise that responsibility in GameVisitor class, which does the trick for you without modifying the structure of each game.

output:

Logging Chess statistics: Game Completion duration, number of moves etc..
Logging Checkers statistics: Game Completion duration, remaining coins of loser
Logging Ludo statistics: Game Completion duration, remaining coins of loser

Decorator

pattern allows behaviour to be added to an individual object, either statically or dynamically, without affecting the behaviour of other objects from the same class

If you are using the GitHub Windows client (as I am) and you are in the situation of having made uncommitted changes that you wish to move to a new branch, you can simply "Crate a new branch" via the GitHub client. It will switch to the newly created branch and preserve your changes.

I think you should call the super.draw() method first before you do anything in surfaceView's draw method.

Use the ActivityInfo (android.content.pm.ActivityInfo) in your onCreate method before calling setLayout method like this

this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

The use-case for CORS is simple. Imagine the site alice.com has some data that the site bob.com wants to access. This type of request traditionally wouldn’t be allowed under the browser’s same origin policy. However, by supporting CORS requests, alice.com can add a few special response headers that allows bob.com to access the data. In order to understand it well, please visit this nice tutorial.. How to solve the issue of CORS

I have just recently been required to work on an application which involved the parsing of an XML document and I agree with Jon Galloway that the LINQ to XML based approach is, in my opinion, the best. I did however have to dig a little to find usable examples, so without further ado, here are a few!

Any comments welcome as this code works but may not be perfect and I would like to learn more about parsing XML for this project!

public void ParseXML(string filePath)  
{  
    // create document instance using XML file path
    XDocument doc = XDocument.Load(filePath);

    // get the namespace to that within of the XML (xmlns="...")
    XElement root = doc.Root;
    XNamespace ns = root.GetDefaultNamespace();

    // obtain a list of elements with specific tag
    IEnumerable<XElement> elements = from c in doc.Descendants(ns + "exampleTagName") select c;

    // obtain a single element with specific tag (first instance), useful if only expecting one instance of the tag in the target doc
    XElement element = (from c in doc.Descendants(ns + "exampleTagName" select c).First();

    // obtain an element from within an element, same as from doc
    XElement embeddedElement = (from c in element.Descendants(ns + "exampleEmbeddedTagName" select c).First();

    // obtain an attribute from an element
    XAttribute attribute = element.Attribute("exampleAttributeName");
}

With these functions I was able to parse any element and any attribute from an XML file no problem at all!

Result Set are actually contains multiple rows of data, and use a cursor to point out current position. So in your case, rs4.getString(1) only get you the data in first column of first row. In order to change to next row, you need to call next()

a quick example

while (rs.next()) {
    String sid = rs.getString(1);
    String lid = rs.getString(2);
    // Do whatever you want to do with these 2 values
}

there are many useful method in ResultSet, you should take a look :)

One work-around is to right-click on the result set and select "Save Results As...". This exports it to a CSV file with the entire contents of the column. Not perfect but worked well enough for me.

This works for me:

Console.OutputEncoding = System.Text.Encoding.Default;

To display some of the symbols, it's required to set Command Prompt's font to Lucida Console:

1. Open Command Prompt;

2. Right click on the top bar of the Command Prompt;

3. Click Properties;

4. If the font is set to Raster Fonts, change it to Lucida Console.

1. Place your image in a div.
2. Give your div explicit square dimensions.
3. Set the CSS overflow property on the div to hidden (overflow:hidden).
4. Put your imagine inside the div.
5. Profit.

For example:

<div style="width:200px;height:200px;overflow:hidden">
    <img src="foo.png" />
</div>
