-Xmn : the size of the heap for the young generation Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor" .

Good size is 33%

document.getElementById('something') can be 'undefined'. Usually (thought not always) it's sufficient to do tests like if (document.getElementById('something')).

I had this problem today where the phone was charging when connected, but wasn't seen by the Mac. It turned out the micro USB cable that I was using was for charging only and didn't do data. Once I changed the USB cable it started working fine.

UITableView has a tableHeaderView property. Set that to whatever view you want up there.

Use a new UIView as a container, add a text label and an image view to that new UIView, then set tableHeaderView to the new view.

For example, in a UITableViewController:

-(void)viewDidLoad
{
     // ...
     UIView *headerView = [[UIView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     [headerView addSubview:imageView];
     UILabel *labelView = [[UILabel alloc] initWithFrame:CGRectMake(XXX, YYY, XXX, YYY)];
     [headerView addSubview:labelView];
     self.tableView.tableHeaderView = headerView;
     [imageView release];
     [labelView release];
     [headerView release];
     // ...
} 

KOUT[i] is a single element of a list. But you are assigning a list to this element. your func is generating a list.

<div style="width:100%;">
    <div style="margin-left:45px;">
       <asp:TextBox ID="txtTitle" runat="server" Width="100%"></asp:TextBox><br />
    </div>
</div>

I remember my CompSci professor saying never to use floats for currency.

The reason for that is how the IEEE specification defines floats in binary format. Basically, it stores sign, fraction and exponent to represent a Float. It's like a scientific notation for binary (something like +1.43*10^2). Because of that, it is impossible to store fractions and decimals in Float exactly.

That's why there is a Decimal format. If you do this:

irb:001:0> "%.47f" % (1.0/10)
=> "0.10000000000000000555111512312578270211815834045" # not "0.1"!

whereas if you just do

irb:002:0> (1.0/10).to_s
=> "0.1" # the interprer rounds the number for you

So if you are dealing with small fractions, like compounding interests, or maybe even geolocation, I would highly recommend Decimal format, since in decimal format 1.0/10 is exactly 0.1.

However, it should be noted that despite being less accurate, floats are processed faster. Here's a benchmark:

require "benchmark" 
require "bigdecimal" 

d = BigDecimal.new(3) 
f = Float(3)

time_decimal = Benchmark.measure{ (1..10000000).each { |i| d * d } } 
time_float = Benchmark.measure{ (1..10000000).each { |i| f * f } }

puts time_decimal 
#=> 6.770960 seconds 
puts time_float 
#=> 0.988070 seconds

Answer

Use float when you don't care about precision too much. For example, some scientific simulations and calculations only need up to 3 or 4 significant digits. This is useful in trading off accuracy for speed. Since they don't need precision as much as speed, they would use float.

Use decimal if you are dealing with numbers that need to be precise and sum up to correct number (like compounding interests and money-related things). Remember: if you need precision, then you should always use decimal.

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

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

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

A bit late, but this could also be useful. There is an IE filter, for IE 5.5+, which you can apply:

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale');

-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(
src='images/logo.gif',
sizingMethod='scale')";

However, this scales the entire image to fit in the allocated area, so if you're using a sprite, this may cause issues.

Specification: AlphaImageLoader Filter @microsoft

Is it possible that you can avoid using wsdl2java? You can straight away use CXF FrontEnd APIs to invoke your SOAP Webservice. The only catch is that you need to create your SEI and VOs on your client end. Here is a sample code.

package com.aranin.weblog4j.client;

import com.aranin.weblog4j.services.BookShelfService;
import com.aranin.weblog4j.vo.BookVO;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;

public class DemoClient {
    public static void main(String[] args){
        String serviceUrl = "http://localhost:8080/weblog4jdemo/bookshelfservice";
        JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean();
        factory.setServiceClass(BookShelfService.class);
        factory.setAddress(serviceUrl);
        BookShelfService bookService = (BookShelfService) factory.create();

        //insert book
        BookVO bookVO = new BookVO();
        bookVO.setAuthor("Issac Asimov");
        bookVO.setBookName("Foundation and Earth");

        String result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        bookVO = new BookVO();
        bookVO.setAuthor("Issac Asimov");
        bookVO.setBookName("Foundation and Empire");

        result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        bookVO = new BookVO();
        bookVO.setAuthor("Arthur C Clarke");
        bookVO.setBookName("Rama Revealed");

        result = bookService.insertBook(bookVO);

        System.out.println("result : " + result);

        //retrieve book

        bookVO = bookService.getBook("Foundation and Earth");

        System.out.println("book name : " + bookVO.getBookName());
        System.out.println("book author : " + bookVO.getAuthor());

    }
}

Put that file in assets.

For project created in Android Studio project you need to create assets folder under the main folder.

Read that file as:

public String loadJSONFromAsset(Context context) {
        String json = null;
        try {
            InputStream is = context.getAssets().open("file_name.json");

            int size = is.available();

            byte[] buffer = new byte[size];

            is.read(buffer);

            is.close();

            json = new String(buffer, "UTF-8");


        } catch (IOException ex) {
            ex.printStackTrace();
            return null;
        }
        return json;

    }

and then you can simply read this string return by this function as

JSONObject obj = new JSONObject(json_return_by_the_function);

For further details regarding JSON see http://www.vogella.com/articles/AndroidJSON/article.html

Hope you will get what you want.

it's better use this example.

Call action and controller using a ActionLink:

@Html.ActionLink("Submit", "Action", "Controller", route, new { @class = "btn btn-block"})

As of Node.js 14.3.0 the top-level await is supported.

Required flag: --experimental-top-level-await.

Another thing on linux is:

send does not allow to operate on non-socket fd. Thus, for example to write on usb port, write is necessary.

Remember that sizes on the web are increasing dramatically. 3 years ago, I did an overhaul to bring our 500 px wide site layout to 1000. Now, where many sites are doing the jump to 1200, we jumped past that and went to a 2560 max optimized for 1600 wide (or 80% depending on the content level) main content area with responsiveness to allow the exact same ratios and look and feel on a laptop (1366x768) and on mobile (1280x720 or smaller).

Dynamic resizing is an integral part of this and will only become more-so as responsiveness becomes more and more important in 2013.

My smartphone has no trouble dealing with the content with 25 items on a page being resized - neither the computation for resizing nor the bandwidth. 3 seconds loads the page from fresh. Looks great on our 6 year old presentation laptop (1366x768) and on the projector (800x600).

Only on Mozilla Firefox does it look genuinely atrocious. It even looks just fine on IE8 (never used/updated since I installed it 2.5 years ago).

jQuery UI Touch Punch just solves it all.

It's a Touch Event Support for jQuery UI. Basically, it just wires touch event back to jQuery UI. Tested on iPad, iPhone, Android and other touch-enabled mobile devices. I used jQuery UI sortable and it works like a charm.

Just use ojdb6.jar and will fix all such issues.

For maven based applications:

1. Download and copy ojdbc6.jar to a directory in your local machine

2. From the location where you have copied your jar install the ojdbc6.jar in your local .M2 Repo by issuing below command C:\SRK\Softwares\Libraries>mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.3 -Dpackaging=jar -Dfile=ojdbc6.jar -DgeneratePom=true

3. Add the below in your project pom.xml as ojdbc6.jar dependency

   <dependency>
       <groupId>com.oracle</groupId>
       <artifactId>ojdbc6</artifactId>
       <version>11.2.0.3</version>
   </dependency>
   

PS: The issue might be due to uses of @Lob annotation in JPA for storing large objects specifically in oracle db columns. Upgrading to 11.2.0.3 (ojdbc6.jar) can resolve the issue.

If you are not using "-XX:HeapDumpPath" option then in case of JBoss EAP/As by default the heap dump file will be generated in "JBOSS_HOME/bin" directory.

If you want to use Android's default drawable, you can use @android:drawable/ic_menu_search like this:

<EditText android:id="@+id/inputSearch"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:drawableLeft="@android:drawable/ic_menu_search"
    android:hint="Search product.."
    android:inputType="textVisiblePassword"/>

As mentioned above @NotNull does nothing on its own. A good way of using @NotNull would be using it with Objects.requireNonNull

public class Foo {
    private final Bar bar;

    public Foo(@NotNull Bar bar) {
        this.bar = Objects.requireNonNull(bar, "bar must not be null");
    }
}

If the file is small, you can read the whole data once:

File file = new File("a.txt");
FileInputStream fis = new FileInputStream(file);
byte[] data = new byte[(int) file.length()];
fis.read(data);
fis.close();

String str = new String(data, "UTF-8");

I don't know of anyway to put a condition in the format specifier, but you can write your own formatter:

using System;
using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
               // all of these don't work
            Console.WriteLine("{0:C}", 10);
            Console.WriteLine("{0:00.0}", 10);
            Console.WriteLine("{0:0}", 10);
            Console.WriteLine("{0:0.00}", 10);
            Console.WriteLine("{0:0}", 10.0);
            Console.WriteLine("{0:0}", 10.1);
            Console.WriteLine("{0:0.00}", 10.1);

          // works
            Console.WriteLine(String.Format(new MyFormatter(),"{0:custom}", 9));
            Console.WriteLine(String.Format(new MyFormatter(),"{0:custom}", 9.1));
            Console.ReadKey();
        }
    }

    class MyFormatter : IFormatProvider, ICustomFormatter
    {
        public string Format(string format, object arg, IFormatProvider formatProvider)
        {
            switch (format.ToUpper())
            {
                case "CUSTOM":
                    if (arg is short || arg is int || arg is long)
                        return arg.ToString();
                    if (arg is Single || arg is Double)
                        return String.Format("{0:0.00}",arg);
                    break;
                // Handle other
                default:
                    try
                    {
                        return HandleOtherFormats(format, arg);
                    }
                    catch (FormatException e)
                    {
                        throw new FormatException(String.Format("The format of '{0}' is invalid.", format), e);
                    }
            }
            return arg.ToString(); // only as a last resort
        }

        private string HandleOtherFormats(string format, object arg)
        {
            if (arg is IFormattable)
                return ((IFormattable)arg).ToString(format, CultureInfo.CurrentCulture);
            if (arg != null)
                return arg.ToString();
            return String.Empty;
        }

        public object GetFormat(Type formatType)
        {
            if (formatType == typeof(ICustomFormatter))
                return this;
            return null;
        }
    }
}

1. Select Project->Properties from the menu bar.

2. Click C/C++ Build on the left in the dialog that comes up.

3. Under the Builder Settings tab on the right, check and make sure the "Build location" is correct.

var stack = [1,2,3,4,5,6];

stack.reverse().shift();

stack.push(0);

Output will be: Array[0,1,2,3,4,5]. This will allow you to keep the same amount of array elements as you push a new value in.

If you want to remove all control characters, including CR and LF, you can use this:

myString.replace(/[^\x20-\x7E]/gmi, "")

It will remove all non-printable characters. This are all characters NOT within the ASCII HEX space 0x20-0x7E. Feel free to modify the HEX range as needed.

Try This:

using System;
using System.Configuration;
using System.Web.Configuration;

namespace SampleApplication.WebConfig
{
    public partial class webConfigFile : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //Helps to open the Root level web.config file.
            Configuration webConfigApp = WebConfigurationManager.OpenWebConfiguration("~");
            //Modifying the AppKey from AppValue to AppValue1
            webConfigApp.AppSettings.Settings["ConnectionString"].Value = "ConnectionString";
            //Save the Modified settings of AppSettings.
            webConfigApp.Save();
        }
    }
}

You can also run ->select('DISTINCT `field`', FALSE) and the second parameter tells CI not to escape the first argument.

With the second parameter as false, the output would be SELECT DISTINCT `field` instead of without the second parameter, SELECT `DISTINCT` `field`

Take a look at rogerdudler/eclipse-ui-themes . In the readme there is a link to a file that you need to extract into your eclipse/dropins folder.

When you have done that go to

Window -> Preferences -> General -> Appearance

And change the theme from GTK (or what ever it is currently) to Dark Juno (or Dark).

That will change the UI to a nice dark theme but to get the complete look and feel you can get the Eclipse Color Theme plugin from eclipsecolorthemes.org. The easiest way is to add this update URI to "Help -> Install New Software" and install it from there.

Eclipse Color Themes

This adds a "Color Theme" menu item under

Window -> Preferences -> Appearance

Where you can select from a large range of editor themes. My preferred one to use with PyDev is Wombat. For Java Solarized Dark

I found Three Way to do this >

1) Using requestWindowFeature

Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(dialog.getWindow().FEATURE_NO_TITLE); 

2) Using style (style.xml)

<style name="FullHeightDialog" parent="android:style/Theme.Dialog">
   <item name="android:windowNoTitle">true</item>
</style>

Dialog dialog = new Dialog(context, R.style.FullHeightDialog);

3) Using XML theme in AndroidManifest.xml

 android:theme="@android:style/Theme.NoTitleBar"

// sample data
$requiredKeys = ['key1', 'key2', 'key3'];
$arrayToValidate = ['key1' => 1, 'key2' => 2, 'key3' => 3];

function keysExist(array $requiredKeys, array $arrayToValidate) {
    if ($requiredKeys === array_keys($arrayToValidate)) {
        return true;
    }

    return false;
}

Add MultipleActiveResultSets=true to the provider part of your connection string. See the example below:

<add name="DbContext" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=dbName;Persist Security Info=True;User ID=userName;Password=password;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />

The best way for paging in sql server 2012 is by using offset and fetch next in a stored procedure. OFFSET Keyword - If we use offset with the order by clause then the query will skip the number of records we specified in OFFSET n Rows.

FETCH NEXT Keywords - When we use Fetch Next with an order by clause only it will returns the no of rows you want to display in paging, without Offset then SQL will generate an error. here is the example given below.

create procedure sp_paging
(
 @pageno as int,
 @records as int
)
as
begin
declare @offsetcount as int
set @offsetcount=(@pageno-1)*@records
select id,bs,variable from salary order by id offset @offsetcount rows fetch Next @records rows only
end

you can execute it as follow.

exec sp_paging 2,3

Your example fails because Thread methods take either one or zero arguments. To create a thread without passing arguments, your code looks like this:

void Start()
{
    // do stuff
}

void Test()
{
    new Thread(new ThreadStart(Start)).Start();
}

If you want to pass data to the thread, you need to encapsulate your data into a single object, whether that is a custom class of your own design, or a dictionary object or something else. You then need to use the ParameterizedThreadStart delegate, like so:

void Start(object data)
{
    MyClass myData = (MyClass)myData;
    // do stuff
}

void Test(MyClass data)
{
    new Thread(new ParameterizedThreadStart(Start)).Start(data);
}

I'm not aware of anything built-in. It's pretty simple to implement:

class assertMethodIsCalled(object):
    def __init__(self, obj, method):
        self.obj = obj
        self.method = method

    def called(self, *args, **kwargs):
        self.method_called = True
        self.orig_method(*args, **kwargs)

    def __enter__(self):
        self.orig_method = getattr(self.obj, self.method)
        setattr(self.obj, self.method, self.called)
        self.method_called = False

    def __exit__(self, exc_type, exc_value, traceback):
        assert getattr(self.obj, self.method) == self.called,
            "method %s was modified during assertMethodIsCalled" % self.method

        setattr(self.obj, self.method, self.orig_method)

        # If an exception was thrown within the block, we've already failed.
        if traceback is None:
            assert self.method_called,
                "method %s of %s was not called" % (self.method, self.obj)

class test(object):
    def a(self):
        print "test"
    def b(self):
        self.a()

obj = test()
with assertMethodIsCalled(obj, "a"):
    obj.b()

This requires that the object itself won't modify self.b, which is almost always true.

In case you also want to include your real name in the from-field, you can use the following format

mailx -r "[email protected] (My Name)" -s "My Subject" ...

If you happen to have non-ASCII characters in you name, like My AEÆoeøaaå (Æ= C3 86, ø= C3 B8, å= C3 A5), you have to encode them like this:

mailx -r "[email protected] (My =?utf-8?Q?AE=C3=86oe=C3=B8aa=C3=A5?=)" -s "My Subject" ...

Hope this can save someone an hour of hard work/research!

It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</div>

the >> appends the output of echo to the file.

Note that there are two reasons this might not work like you want it to. You may be aware of these, but I mention them just in case.

First, it won't affect a web browser, for example, that already has the current, "real" IP address resolved. So, it won't always take effect right away.

Second, it requires you to add an entry for every host name on a domain; just adding websitename.com will not block www.websitename.com, for example.

I thought I lose all my hairs for solving this 'challenge'. I faced following problems:

1. How to deserialize nested objects, lists etc.
2. I like constructors with specified fields
3. I don't like dynamic fields
4. I don't like hacky solutions

I found a library called jsonpickle which is has proven to be really useful.

Installation:

pip install jsonpickle

Here is a code example with writing nested objects to file:

import jsonpickle


class SubObject:
    def __init__(self, sub_name, sub_age):
        self.sub_name = sub_name
        self.sub_age = sub_age


class TestClass:

    def __init__(self, name, age, sub_object):
        self.name = name
        self.age = age
        self.sub_object = sub_object


john_junior = SubObject("John jr.", 2)

john = TestClass("John", 21, john_junior)

file_name = 'JohnWithSon' + '.json'

john_string = jsonpickle.encode(john)

with open(file_name, 'w') as fp:
    fp.write(john_string)

john_from_file = open(file_name).read()

test_class_2 = jsonpickle.decode(john_from_file)

print(test_class_2.name)
print(test_class_2.age)
print(test_class_2.sub_object.sub_name)

Output:

John
21
John jr.

You can fake the disabled effect using CSS.

I had success following the answer by kellen with the vital update from Toby J, but had to make this revision:

When creating the self-signed certificate, it was necessary to place the new subjectAltName field under the v3_ca extensions, instead of v3_req. I copied /etc/ssl/openssl.conf to a temporary file and then added a line subjectAltName = DNS:*.example.com under [ v3_ca ]. Then passed that file to the cert creation command, something like

  openssl req -x509 -nodes -newkey rsa:2048 \
          -config /tmp/openssl-revised.cfg \
          -keyout example.com.key -out example.com.crt

and followed kellen's updated steps.

You can also just add an ON CONFLICT REPLACE clause to your user_name unique constraint and then just INSERT away, leaving it to SQLite to figure out what to do in case of a conflict. See:https://sqlite.org/lang_conflict.html.

Also note the sentence regarding delete triggers: When the REPLACE conflict resolution strategy deletes rows in order to satisfy a constraint, delete triggers fire if and only if recursive triggers are enabled.

You can use closures to pass parameters:

iframe.document.addEventListener('click', function(event) {clic(this.id);}, false);

However, I recommend that you use a better approach to access your frame (I can only assume that you are using the DOM0 way of accessing frame windows by their name - something that is only kept around for backwards compatibility):

document.getElementById("myFrame").contentDocument.addEventListener(...);

By their mathematical definition, OR and AND are binary operators; they verify the LHS and RHS conditions regardless, similarly to | and &.

|| and && alter the properties of the OR and AND operators by stopping them when the LHS condition isn't fulfilled.

You could use:

NSString *stringWithoutSpaces = [myString 
   stringByReplacingOccurrencesOfString:@" " withString:@""];

The <passwordHash> element in users/<username>/config.xml will accept data of the format

salt:sha256("password{salt}")

So, if your salt is bar and your password is foo then you can produce the SHA256 like this:

echo -n 'foo{bar}' | sha256sum

You should get 7f128793bc057556756f4195fb72cdc5bd8c5a74dee655a6bfb59b4a4c4f4349 as the result. Take the hash and put it with the salt into <passwordHash>:

<passwordHash>bar:7f128793bc057556756f4195fb72cdc5bd8c5a74dee655a6bfb59b4a4c4f4349</passwordHash>

Restart Jenkins, then try logging in with password foo. Then reset your password to something else. (Jenkins uses bcrypt by default, and one round of SHA256 is not a secure way to store passwords. You'll get a bcrypt hash stored when you reset your password.)

The short answer

There is none. They are exactly the same.

The long answer

Both .htm and .html are exactly the same and will work in the same way. The choice is down to personal preference, provided you’re consistent with your file naming you won’t have a problem with either.

Depending on the configuration of the web server, one of the file types will take precedence over the other. This should not be an issue since it’s unlikely that you’ll have both index.htm and index.html sitting in the same folder.

We always use the shorter .htm for our file names since file extensions are typically 3 characters long.

AND MORE ON: http://www.sightspecific.com/~mosh/WWW_FAQ/ext.html or http://www.sightspecific.com/~mosh/WWW_FAQ/ext.htm

I think I should add this part here:
There is one single slight difference between .htm and .html files. Consider a path in your server like: mydomain.com/myfolder. If you create an index.htm file inside that folder and you open that like this:mydomain.com/myfolder/, it will goes crazy and spit out your files as it is in your server,
but if you create an index.html file in there and open that directory in your browser, it will load that file. I tested this on my VPS and found this Maybe you could somehow set your server to load index.htm files by default, but I guess the .html file is the default file type for browsers to open in each directory.

I added this for an answer to another question and seemed relevant. Hopefully might help someone that needs to change the value of the keys in an array. Uses built-in functions for php.

$inputArray = array('app_test' => 'test', 'app_two' => 'two');

/**
 * Used to remap keys of an array by removing the prefix passed in
 * 
 * Example:
 * $inputArray = array('app_test' => 'test', 'app_two' => 'two');
 * $keys = array_keys($inputArray);
 * array_walk($keys, 'removePrefix', 'app_');
 * $remappedArray = array_combine($keys, $inputArray);
 *
 * @param $value - key value to replace, should be from array_keys
 * @param $omit - unused, needed for prefix call
 * @param $prefix - prefix to string replace in keys
 */
function removePrefix(&$value, $omit, $prefix) {
    $value = str_replace($prefix, '', $value);
}

// first get all the keys to remap
$keys = array_keys($inputArray);

// perform internal iteration with prefix passed into walk function for dynamic replace of key
array_walk($keys, 'removePrefix', 'app_');

// combine the rewritten keys and overwrite the originals
$remappedArray = array_combine($keys, $inputArray);

// see full output of comparison
var_dump($inputArray);
var_dump($remappedArray);

Output:

array(2) {
  'attr_test' =>
  string(4) "test"
  'attr_two' =>
  string(3) "two"
}
array(2) {
  'test' =>
  string(4) "test"
  'two' =>
  string(3) "two"
}

Normalize.css is mainly a set of styles, based on what its author thought would look good, and make it look consistent across browsers. Reset basically strips styling from elements so you have more control over the styling of everything.

I use both.

Some styles from Reset, some from Normalize.css. For example, from Normalize.css, there's a style to make sure all input elements have the same font, which doesn't occur (between text inputs and textareas). Reset has no such style, so inputs have different fonts, which is not normally wanted.

So bascially, using the two CSS files does a better job 'Equalizing' everything ;)

We use the bulk insert as well. The file we upload is sent from an external party. After a while of troubleshooting, I realized that their file had columns with commas in it. Just another thing to look for...

HTML4 specification states that:

Inline elements may contain only data and other inline elements

Span is an inline element, therefore having span inside span is valid. There's a related question: Can <span> tags have any type of tags inside them? which makes it completely clear.

HTML5 specification (including the most current draft of HTML 5.3 dated November 16, 2017) changes terminology, but it's still perfectly valid to place span inside another span.

If you still look for a solution, here's one that combined other answers (Bart Kiers and culmat) for your reference:

Usage:
HintTextField field = new HintTextField();
field.setHint("Here's a hint");

javax.el.PropertyNotFoundException: Property 'foo' not found on type com.example.Bean

This literally means that the mentioned class com.example.Bean doesn't have a public (non-static!) getter method for the mentioned property foo. Note that the field itself is irrelevant here!

The public getter method name must start with get, followed by the property name which is capitalized at only the first letter of the property name as in Foo.

public Foo getFoo() {
    return foo;
}

You thus need to make sure that there is a getter method matching exactly the property name, and that the method is public (non-static) and that the method does not take any arguments and that it returns non-void. If you have one and it still doesn't work, then chances are that you were busy editing code forth and back without firmly cleaning the build, rebuilding the code and redeploying/restarting the application. You need to make sure that you have done so.

For boolean (not Boolean!) properties, the getter method name must start with is instead of get.

public boolean isFoo() {
    return foo;
}

Regardless of the type, the presence of the foo field itself is thus not relevant. It can have a different name, or be completely absent, or even be static. All of below should still be accessible by ${bean.foo}.

public Foo getFoo() {
    return bar;
}

public Foo getFoo() {
    return new Foo("foo");
}

public Foo getFoo() {
    return FOO_CONSTANT;
}

You see, the field is not what counts, but the getter method itself. Note that the property name itself should not be capitalized in EL. In other words, ${bean.Foo} won't ever work, it should be ${bean.foo}.

I was using nano, and it took me a long time to figure out this error. My problem was I was using the wrong port. I had port 5948 instead of 5984.

var nano = require('nano')('http://localhost:5984');
var db = nano.use('address');
var app = express();

I assume that since you're using an XML declaration, you're not worrying about IE or older browsers.

So you can use display:table-cell and display:table-row like so:

This solution will change the existing dataframe itself:

mydf = pd.DataFrame({"BrandName":["A", "B", "ABC", "D", "AB"], "Speciality":["H", "I", "J", "K", "L"]})
mydf["BrandName"].replace(["ABC", "AB"], "A", inplace=True)

In C# if you declare a string variable and if you don’t assign any value to that variable, then by default that variable takes a null value. In such a case, if you use the ToString() method then your program will throw the null reference exception. On the other hand, if you use the Convert.ToString() method then your program will not throw an exception.

mainWB.Sheets.Add(After:=Sheets(Sheets.Count)).Name = new_sheet_name 

should probably be

mainWB.Sheets.Add(After:=mainWB.Sheets(mainWB.Sheets.Count)).Name = new_sheet_name 

Tool: Using Proguard in your application it can be restricted to reverse engineering your application

A better answer is to leave your script as it was. When doing the Select name, follow it by -ExpandProperty Name like so:

Get-ADGroupMember 'Domain Admins' | Select Name -ExpandProperty Name | out-file Admins.txt

It depends.

When you commit to sending output to stdout, you're basically leaving it up to the user to decide where that output should go.

If you use printf(...) (or the equivalent fprintf(stdout, ...)), you're sending the output to stdout, but where that actually ends up can depend on how I invoke your program.

If I launch your program from my console like this, I'll see output on my console:

$ prog
Hello, World! # <-- output is here on my console

However, I might launch the program like this, producing no output on the console:

$ prog > hello.txt

but I would now have a file "hello.txt" with the text "Hello, World!" inside, thanks to the shell's redirection feature.

Who knows – I might even hook up some other device and the output could go there. The point is that when you decide to print to stdout (e.g. by using printf()), then you won't exactly know where it will go until you see how the process is launched or used.

Since git 1.8.5 (Q4 2013):

"git fetch" (hence "git pull" as well) learned to check "fetch.prune" and "remote.*.prune" configuration variables and to behave as if the "--prune" command line option was given.

That means that, if you set remote.origin.prune to true:

git config remote.origin.prune true

Any git fetch or git pull will automatically prune.

Note: Git 2.12 (Q1 2017) will fix a bug related to this configuration, which would make git remote rename misbehave.
See "How do I rename a git remote?".

See more at commit 737c5a9:

Without "git fetch --prune", remote-tracking branches for a branch the other side already has removed will stay forever.
Some people want to always run "git fetch --prune".

To accommodate users who want to either prune always or when fetching from a particular remote, add two new configuration variables "fetch.prune" and "remote.<name>.prune":

• "fetch.prune" allows to enable prune for all fetch operations.
• "remote.<name>.prune" allows to change the behaviour per remote.

The latter will naturally override the former, and the --[no-]prune option from the command line will override the configured default.

Since --prune is a potentially destructive operation (Git doesn't keep reflogs for deleted references yet), we don't want to prune without users consent, so this configuration will not be on by default.

A quick step-by-step guide how to configure NetBeans default encoding UTF-8. In result NetBeans will create all new files in UTF-8 encoding.

NetBeans default encoding UTF-8 step-by-step guide

• Go to etc folder in NetBeans installation directory

• Edit netbeans.conf file

• Find netbeans_default_options line

• Add -J-Dfile.encoding=UTF-8 inside quotation marks inside that line

  (example: netbeans_default_options="-J-Dfile.encoding=UTF-8")

• Restart NetBeans

You set NetBeans default encoding UTF-8.

Your netbeans_default_options may contain additional parameters inside the quotation marks. In such case, add -J-Dfile.encoding=UTF-8 at the end of the string. Separate it with space from other parameters.

Example:

netbeans_default_options="-J-client -J-Xss128m -J-Xms256m -J-XX:PermSize=32m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.java2d.dpiaware=true -J-Dsun.zip.disableMemoryMapping=true -J-Dfile.encoding=UTF-8"

Yeah I agree with your approach. To merge mobiledevicesupport into master you can use

git checkout master
git pull origin master //Get all latest commits of master branch
git merge mobiledevicesupport

Similarly you can also merge master in mobiledevicesupport.

Q. If cross merging is an issue or not.

A. Well it depends upon the commits made in mobile* branch and master branch from the last time they were synced. Take this example: After last sync, following commits happen to these branches

Master branch: A -> B -> C [where A,B,C are commits]
Mobile branch: D -> E

Now, suppose commit B made some changes to file a.txt and commit D also made some changes to a.txt. Let us have a look at the impact of each operation of merging now,

git checkout master //Switches to master branch
git pull // Get the commits you don't have. May be your fellow workers have made them.
git merge mobiledevicesupport // It will try to add D and E in master branch.

Now, there are two types of merging possible

1. Fast forward merge
2. True merge (Requires manual effort)

Git will first try to make FF merge and if it finds any conflicts are not resolvable by git. It fails the merge and asks you to merge. In this case, a new commit will occur which is responsible for resolving conflicts in a.txt.

So Bottom line is Cross merging is not an issue and ultimately you have to do it and that is what syncing means. Make sure you dirty your hands in merging branches before doing anything in production.

Also remember one thing. Very important
You have to specify the command something like this to be more precise
grep -l "pattern" *

Date.js is a handy library for manipulating and formatting dates. It can help in this situation.

If your textbox is a Required field and have some regex pattern to match and has minlength and maxlength

TestBox code

<input type="text" name="myfieldname" ng-pattern="/^[ A-Za-z0-9_@./#&+-]*$/" ng-minlength="3" ng-maxlength="50" class="classname" ng-model="model.myfieldmodel">

Ng-Class to Add

ng-class="{ 'err' :  myform.myfieldname.$invalid || (myform.myfieldname.$touched && !model.myfieldmodel.length) }"

This error can occur on anything that requires elevated privileges in Windows.

It happens when the "Application Information" service is disabled in Windows services. There are a few viruses that use this as an attack vector to prevent people from removing the virus. It also prevents people from installing software to remove viruses.

The normal way to fix this would be to run services.msc, or to go into Administrative Tools and run "Services". However, you will not be able to do that if the "Application Information" service is disabled.

Instead, reboot your computer into Safe Mode (reboot and press F8 until the Windows boot menu appears, select Safe Mode with Networking). Then run services.msc and look for services that are designated as "Disabled" in the Startup Type column. Change these "Disabled" services to "Automatic".

Make sure the "Application Information" service is set to a Startup Type of "Automatic".

When you are done enabling your services, click Ok at the bottom of the tool and reboot your computer back into normal mode. The problem should be resolved when Windows reboots.

The standard Web Storage, does not say anything about the restoring any of these. So there won't be any standard way to do it. You have to go through the way the browsers implement these, or find a way to backup these before you delete them.

This is because the content of

<p myHighlight>Highlight me!</p>

has not been rendered when the constructor of the HighlightDirective is called so there is no content yet.

If you implement the AfterContentInit hook you will get the element and its content.

import { Directive, ElementRef, AfterContentInit } from '@angular/core';

@Directive({ selector: '[myHighlight]' })

export class HighlightDirective {

    constructor(private el: ElementRef) {
        //el.nativeElement.style.backgroundColor = 'yellow';
    }

    ngAfterContentInit(){
        //you can get to the element content here 
        //this.el.nativeElement
    }
}

I had the same problem while debugging a class library from a testbed web app. I was referencing the release version in the testbed and that was set to be optimised in the class library properties.

Un-ticking the optimise code checkbox for the release version in the class library properties, just while I am writing it, has solved the issue.

Just use "javascript:" in your action attribute of form if you are not using action.

You may check *spell en-GB dictionary used by Mozilla, OpenOffice, plenty of other software.

Conaider this situation:

Mark and Lisa are secretly a couple, and because of age difference they are not allowed to be together. Mark and Lisa meet every night when nobody is watching. They have estabilished their own set of rules how to comunicate when the time comes. He stands in her garden and throws the small rock at her window. Lisa knows that it is time, and responds by waving from the window and opening it afterwards so Mark can climb in. That was example how the API works. The rock is initial request to another end. Another end waves, opens the window which basicaly means "Welcome in!".

API is almost like human language but for computers.

To find all tables with a particular column:

select owner, table_name from all_tab_columns where column_name = 'ID';

To find tables that have any or all of the 4 columns:

select owner, table_name, column_name
from all_tab_columns
where column_name in ('ID', 'FNAME', 'LNAME', 'ADDRESS');

To find tables that have all 4 columns (with none missing):

select owner, table_name
from all_tab_columns
where column_name in ('ID', 'FNAME', 'LNAME', 'ADDRESS')
group by owner, table_name
having count(*) = 4;

SQLFiddle will let you test out your queries, while it doesn't explicitly correct syntax etc. per se it does let you play around with the script and will definitely let you know if things are working or not.

Definitely not the most correct way, but if you just need a quick solution to get the date without the time and you do not wish to use a third party library this should do

    Date db = db.substring(0, 10) + db.substring(23,28);

I only needed the date for visual purposes and couldn't Joda so I substringed.

$("#selectsearch").change(function() {
  var action = $(this).val() == "people" ? "user" : "content";
  $("#search-form").attr("action", "/search/" + action);
});

For url with aplication alias like http://example.com/appAlias/... You can try this:

var req = HttpContext.Current.Request;
string baseUrl = string.Format("{0}://{1}/{2}", req.Url.Scheme, req.Url.Authority, req.ApplicationPath);

To center the div on a page, check the fiddle link.

#vh {_x000D_
    margin: auto;_x000D_
    position: absolute;_x000D_
    top: 0;_x000D_
    left: 0;_x000D_
    bottom: 0;_x000D_
    right: 0;_x000D_
}_x000D_
.box{_x000D_
    border-radius: 15px;_x000D_
    box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);_x000D_
    padding: 25px;_x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
    background: white;_x000D_
}

<div id="vh" class="box">Div to be aligned vertically</div>

Another option is to use flex box, check the fiddle link.

.vh {_x000D_
    background-color: #ddd;_x000D_
    height: 400px;_x000D_
    align-items: center;_x000D_
    display: flex;_x000D_
}_x000D_
.vh > div {_x000D_
    width: 100%;_x000D_
    text-align: center;_x000D_
    vertical-align: middle;_x000D_
}

<div class="vh">_x000D_
    <div>Div to be aligned vertically</div>_x000D_
</div>

Another option is to use a CSS 3 transform:

#vh {_x000D_
    position: absolute;_x000D_
    top: 50%;_x000D_
    left: 50%;_x000D_
    /*transform: translateX(-50%) translateY(-50%);*/_x000D_
    transform: translate(-50%, -50%);_x000D_
}_x000D_
.box{_x000D_
    border-radius: 15px;_x000D_
    box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);_x000D_
    padding: 25px;_x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
    background: white;_x000D_
}

<div id="vh" class="box">Div to be aligned vertically</div>

You can achieve that be using this simple extension method

public static class IEnumerableExtensions
{

    public static IEnumerable<t> Randomize<t>(this IEnumerable<t> target)
    {
        Random r = new Random();

        return target.OrderBy(x=>(r.Next()));
    }        
}

and you can use it by doing the following

// use this on any collection that implements IEnumerable!
// List, Array, HashSet, Collection, etc

List<string> myList = new List<string> { "hello", "random", "world", "foo", "bar", "bat", "baz" };

foreach (string s in myList.Randomize())
{
    Console.WriteLine(s);
}

Here's yet another approach that allows you to choose which mounted components you want the window scroll position to reset to without mass duplicating the ComponentDidUpdate/ComponentDidMount.

The example below is wrapping the Blog component with ScrollIntoView(), so that if the route changes when the Blog component is mounted, then the HOC's ComponentDidUpdate will update the window scroll position.

You can just as easily wrap it over the entire app, so that on any route change, it'll trigger a window reset.

ScrollIntoView.js

import React, { Component } from 'react';
import { withRouter } from 'react-router';

export default WrappedComponent => {
  class ResetWindowScroll extends Component {
    componentDidUpdate = (prevProps) => {
      if(this.props.location !== prevProps.location) window.scrollTo(0,0);
    }

    render = () => <WrappedComponent {...this.props} />
  }
  return withRouter(ResetWindowScroll);
}

Routes.js

import React from 'react';
import { Route, IndexRoute } from 'react-router';

import App from '../components/App';
import About from '../components/pages/About';
import Blog from '../components/pages/Blog'
import Index from '../components/Landing';
import NotFound from '../components/navigation/NotFound';
import ScrollIntoView from '../components/navigation/ScrollIntoView';

 export default (
    <Route path="/" component={App}>
        <IndexRoute component={Index} />
        <Route path="/about" component={About} /> 
        <Route path="/blog" component={ScrollIntoView(Blog)} />
        <Route path="*" component={NotFound} />
    </Route>
);

The above example works great, but if you've migrated to react-router-dom, then you can simplify the above by creating a HOC that wraps the component.

Once again, you could also just as easily wrap it over your routes (just change componentDidMount method to the componentDidUpdate method example code written above, as well as wrapping ScrollIntoView with withRouter).

containers/ScrollIntoView.js

import { PureComponent, Fragment } from "react";

class ScrollIntoView extends PureComponent {
  componentDidMount = () => window.scrollTo(0, 0);

  render = () => this.props.children
}

export default ScrollIntoView;

components/Home.js

import React from "react";
import ScrollIntoView from "../containers/ScrollIntoView";

export default () => (
  <ScrollIntoView>
    <div className="container">
      <p>
        Sample Text
      </p>
    </div>
  </ScrollIntoView>
);

Use a std::wstring instead of a C99 variable length array. The current standard guarantees a contiguous buffer for std::basic_string. E.g.,

std::wstring wc( cSize, L'#' );
mbstowcs( &wc[0], c, cSize );

C++ does not support C99 variable length arrays, and so if you compiled your code as pure C++, it would not even compile.

With that change your function return type should also be std::wstring.

Remember to set relevant locale in main.

E.g., setlocale( LC_ALL, "" ).

Cheers & hth.,

This is one of those things that can be difficult to search for if you don't already know where to look.

[ is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.

There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.

[ is equivalent to the test command, except that [ requires ] as its last argument, and test does not.

Assuming the bash documentation is installed on your system, if you type info bash and search for 'test' or '[' (the apostrophes are part of the search), you'll find the documentation for the [ command, also known as the test command. If you use man bash instead of info bash, search for ^ *test (the word test at the beginning of a line, following some number of spaces).

Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, != is the string inequality operator.

You can also find bash documentation on the web.

• Bash reference
• Bourne shell builtins (including test and [)
• Bash Conditional Expressions -- (Scroll to the bottom; -ne is under "arg1 OP arg2")
• POSIX documentation for test

The official definition of the test command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).

You can use this for your purpose.

In parent form:

private void addCustomerToolStripMenuItem_Click(object sender, EventArgs e)
{
    CustomerPage f = new CustomerPage();
    f.LoadType = 1;
    f.MdiParent = this;
    f.Show();            
    f.Focus();
}

In child form:

public int LoadType{get;set;}

private void CustomerPage_Load(object sender, EventArgs e)
{        
    if (LoadType == 1)
    {
        this.button1.Visible = false;
    }
}

tl;dr

Instant and LocalDateTime are two entirely different animals: One represents a moment, the other does not.

• Instant represents a moment, a specific point in the timeline.
• LocalDateTime represents a date and a time-of-day. But lacking a time zone or offset-from-UTC, this class cannot represent a moment. It represents potential moments along a range of about 26 to 27 hours, the range of all time zones around the globe. A LocalDateTime value is inherently ambiguous.

Incorrect Presumption

LocalDateTime is rather date/clock representation including time-zones for humans.

Your statement is incorrect: A LocalDateTime has no time zone. Having no time zone is the entire point of that class.

To quote that class’ doc:

This class does not store or represent a time-zone. Instead, it is a description of the date, as used for birthdays, combined with the local time as seen on a wall clock. It cannot represent an instant on the time-line without additional information such as an offset or time-zone.

So Local… means “not zoned, no offset”.

Instant

An Instant is a moment on the timeline in UTC, a count of nanoseconds since the epoch of the first moment of 1970 UTC (basically, see class doc for nitty-gritty details). Since most of your business logic, data storage, and data exchange should be in UTC, this is a handy class to be used often.

Instant instant = Instant.now() ;  // Capture the current moment in UTC.

OffsetDateTime

The class OffsetDateTime class represents a moment as a date and time with a context of some number of hours-minutes-seconds ahead of, or behind, UTC. The amount of offset, the number of hours-minutes-seconds, is represented by the ZoneOffset class.

If the number of hours-minutes-seconds is zero, an OffsetDateTime represents a moment in UTC the same as an Instant.

ZoneOffset

The ZoneOffset class represents an offset-from-UTC, a number of hours-minutes-seconds ahead of UTC or behind UTC.

A ZoneOffset is merely a number of hours-minutes-seconds, nothing more. A zone is much more, having a name and a history of changes to offset. So using a zone is always preferable to using a mere offset.

ZoneId

A time zone is represented by the ZoneId class.

A new day dawns earlier in Paris than in Montréal, for example. So we need to move the clock’s hands to better reflect noon (when the Sun is directly overhead) for a given region. The further away eastward/westward from the UTC line in west Europe/Africa the larger the offset.

A time zone is a set of rules for handling adjustments and anomalies as practiced by a local community or region. The most common anomaly is the all-too-popular lunacy known as Daylight Saving Time (DST).

A time zone has the history of past rules, present rules, and rules confirmed for the near future.

These rules change more often than you might expect. Be sure to keep your date-time library's rules, usually a copy of the 'tz' database, up to date. Keeping up-to-date is easier than ever now in Java 8 with Oracle releasing a Timezone Updater Tool.

Specify a proper time zone name in the format of Continent/Region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 2-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

Time Zone = Offset + Rules of Adjustments

ZoneId z = ZoneId.of( “Africa/Tunis” ) ; 

ZonedDateTime

Think of ZonedDateTime conceptually as an Instant with an assigned ZoneId.

ZonedDateTime = ( Instant + ZoneId )

To capture the current moment as seen in the wall-clock time used by the people of a particular region (a time zone):

ZonedDateTime zdt = ZonedDateTime.now( z ) ;  // Pass a `ZoneId` object such as `ZoneId.of( "Europe/Paris" )`. 

Nearly all of your backend, database, business logic, data persistence, data exchange should all be in UTC. But for presentation to users you need to adjust into a time zone expected by the user. This is the purpose of the ZonedDateTime class and the formatter classes used to generate String representations of those date-time values.

ZonedDateTime zdt = instant.atZone( z ) ;
String output = zdt.toString() ;                 // Standard ISO 8601 format.

You can generate text in localized format using DateTimeFormatter.

DateTimeFormatter f = DateTimeFormatter.ofLocalizedDateTime( FormatStyle.FULL ).withLocale( Locale.CANADA_FRENCH ) ; 
String outputFormatted = zdt.format( f ) ;

LocalDate, LocalTime, LocalDateTime

The "local" date time classes, LocalDateTime, LocalDate, LocalTime, are a different kind of critter. The are not tied to any one locality or time zone. They are not tied to the timeline. They have no real meaning until you apply them to a locality to find a point on the timeline.

The word “Local” in these class names may be counter-intuitive to the uninitiated. The word means any locality, or every locality, but not a particular locality.

So for business apps, the "Local" types are not often used as they represent just the general idea of a possible date or time not a specific moment on the timeline. Business apps tend to care about the exact moment an invoice arrived, a product shipped for transport, an employee was hired, or the taxi left the garage. So business app developers use Instant and ZonedDateTime classes most commonly.

So when would we use LocalDateTime? In three situations:

• We want to apply a certain date and time-of-day across multiple locations.
• We are booking appointments.
• We have an intended yet undetermined time zone.

Notice that none of these three cases involve a single certain specific point on the timeline, none of these are a moment.

One time-of-day, multiple moments

Sometimes we want to represent a certain time-of-day on a certain date, but want to apply that into multiple localities across time zones.

For example, "Christmas starts at midnight on the 25th of December 2015" is a LocalDateTime. Midnight strikes at different moments in Paris than in Montréal, and different again in Seattle and in Auckland.

LocalDate ld = LocalDate.of( 2018 , Month.DECEMBER , 25 ) ;
LocalTime lt = LocalTime.MIN ;   // 00:00:00
LocalDateTime ldt = LocalDateTime.of( ld , lt ) ;  // Christmas morning anywhere. 

Another example, "Acme Company has a policy that lunchtime starts at 12:30 PM at each of its factories worldwide" is a LocalTime. To have real meaning you need to apply it to the timeline to figure the moment of 12:30 at the Stuttgart factory or 12:30 at the Rabat factory or 12:30 at the Sydney factory.

Booking appointments

Another situation to use LocalDateTime is for booking future events (ex: Dentist appointments). These appointments may be far enough out in the future that you risk politicians redefining the time zone. Politicians often give little forewarning, or even no warning at all. If you mean "3 PM next January 23rd" regardless of how the politicians may play with the clock, then you cannot record a moment – that would see 3 PM turn into 2 PM or 4 PM if that region adopted or dropped Daylight Saving Time, for example.

For appointments, store a LocalDateTime and a ZoneId, kept separately. Later, when generating a schedule, on-the-fly determine a moment by calling LocalDateTime::atZone( ZoneId ) to generate a ZonedDateTime object.

ZonedDateTime zdt = ldt.atZone( z ) ;  // Given a date, a time-of-day, and a time zone, determine a moment, a point on the timeline.

If needed, you can adjust to UTC. Extract an Instant from the ZonedDateTime.

Instant instant = zdt.toInstant() ;  // Adjust from some zone to UTC. Same moment, same point on the timeline, different wall-clock time.

Unknown zone

Some people might use LocalDateTime in a situation where the time zone or offset is unknown.

I consider this case inappropriate and unwise. If a zone or offset is intended but undetermined, you have bad data. That would be like storing a price of a product without knowing the intended currency (dollars, pounds, euros, etc.). Not a good idea.

All date-time types

For completeness, here is a table of all the possible date-time types, both modern and legacy in Java, as well as those defined by the SQL standard. This might help to place the Instant & LocalDateTime classes in a larger context.

Notice the odd choices made by the Java team in designing JDBC 4.2. They chose to support all the java.time times… except for the two most commonly used classes: Instant & ZonedDateTime.

But not to worry. We can easily convert back and forth.

Converting Instant.

// Storing
OffsetDateTime odt = instant.atOffset( ZoneOffset.UTC ) ;
myPreparedStatement.setObject( … , odt ) ;

// Retrieving
OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;
Instant instant = odt.toInstant() ;

Converting ZonedDateTime.

// Storing
OffsetDateTime odt = zdt.toOffsetDateTime() ;
myPreparedStatement.setObject( … , odt ) ;

// Retrieving
OffsetDateTime odt = myResultSet.getObject( … , OffsetDateTime.class ) ;
ZoneId z = ZoneId.of( "Asia/Kolkata" ) ;
ZonedDateTime zdt = odt.atZone( z ) ; 

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

It seems like that it is only me who are so clumsy, because i have yet to found a solution that my case required.

I am developing a multi-modular project, thus base android module configuration is extracted in single gradle script. All the concrete versions of sdks/libs are also extracted in a script.

A script containing versions looked like this:

...

ext.androidVersions = [
    compile_sdk_version     : '27',
    min_sdk_version         : '19',
    target_sdk_version      : '27',
    build_tool_version      : '27.0.3',
    application_id          : 'com.test.test',
]

...

Not accustomed to groovy syntax my eye has not spotted that the values for compile, min and target sdks were not integers but STRINGS! Therefore a compiler rightfully complained about not being able to find an sdk a version of which would match HASH STRING '27'.

So the solution would be to make sdk's versions integers: ...

ext.androidVersions = [
    compile_sdk_version     : 27,
    min_sdk_version         : 19,
    target_sdk_version      : 27,
    build_tool_version      : '27.0.3',
    application_id          : 'com.test.test',
]

...

Here's an implementation of URL Safe encryption and Decryption using AES(PyCrypto) and base64.

import base64
from Crypto import Random
from Crypto.Cipher import AES

AKEY = b'mysixteenbytekey' # AES key must be either 16, 24, or 32 bytes long

iv = Random.new().read(AES.block_size)

def encode(message):
    obj = AES.new(AKEY, AES.MODE_CFB, iv)
    return base64.urlsafe_b64encode(obj.encrypt(message))

def decode(cipher):
    obj2 = AES.new(AKEY, AES.MODE_CFB, iv)
    return obj2.decrypt(base64.urlsafe_b64decode(cipher))

If you face some issue like this https://bugs.python.org/issue4329 (TypeError: character mapping must return integer, None or unicode) use str(cipher) while decoding as follows:

return obj2.decrypt(base64.urlsafe_b64decode(str(cipher)))

Test:

<textarea ><?php echo htmlentities($page_html); ?></textarea>

works fine for me..

"keeping in mind Alexander's suggestion, here is why I think this is a good approach"

if we just try plain <textarea> it may not always work since there may be closing textarea tags which may wrongly close the parent tag and display rest of the HTML source on the parent document, which would look awkward.

using htmlentities converts all applicable characters such as < > to HTML entities which eliminates any possibility of leaks.

There maybe benefits or shortcomings to this approach or a better way of achieving the same results, if so please comment as I would love to learn from them :)

Use javascript:

<button onclick="window.location.href='/css_page.html'">CSS page</button>

You can always style the button in css anyaways. Hope it helped!

Good luck!

Here is a bash script inspired by abarnert's answer which will unpack a package named MyPackage.pkg into a subfolder named MyPackage_pkg and then open the folder in Finder.

    #!/usr/bin/env bash
    filename="$*"
    dirname="${filename/\./_}"
    pkgutil --expand "$filename" "$dirname"
    cd "$dirname"
    tar xvf Payload
    open .

Usage:

    pkg-upack.sh MyPackage.pkg

Warning: This will not work in all cases, and will fail with certain files, e.g. the PKGs inside the OSX system installer. If you want to peek inside the pkg file and see what's inside, you can try SuspiciousPackage (free app), and if you need more options such as selectively unpacking specific files, then have a look at Pacifist (nagware).

make a class for that button lets say :

`<input type="button" value="+" class="b1" onclick="addRow()">`

your js should look like this :

$(document).ready(function(){
  $('.b1').click(function(){
      $('div').append('<input type="text"..etc ');
  });
});

use java decompiler. http://jd.benow.ca/. you can open the jar files.

Thanks, Manirathinam.

You can do something similar:

var tuple = Object.freeze({ name:'Bob', age:14 })

and then refer to name and age as attributes

tuple.name 
tuple.age 

No need to import any special libraries to do this.

Use normal syntax and it will open the file for reading then close it.

with open("/etc/hostname","r") as f: print f.read() 

or

with open("/etc/hosts","r") as f: x = f.read().splitlines()

which gives you an array x containing the lines, and can be printed like so:

for line in x: print line

These one-liners are very helpful for maintenance - basically self-documenting.

Since I found that the above approved answer lacks some clarity and the op provides an incorrect solution that he/she will use. I therefore hope that the below example will help others. The solution is more or less portable as well.

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

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

Example straight from the API:

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

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

Guys using autolayout and your sizetofit isn't working, then please check your width constraint once. If you had missed the width constraint then the height will be accurate.

No need to use any other API. just one line would fix all the issue.

[_textView sizeToFit];

Here, I was only concerned with height, keeping the width fixed and had missed the width constraint of my TextView in storyboard.

And this was to show up the dynamic content from the services.

Hope this might help..

Underscore.js has a nice method for that:

myArray = [{'id':'73','foo':'bar'},{'id':'45','foo':'bar'},etc.]
obj = _.find(myArray, function(obj) { return obj.id == '45' })

This worked for me:

• put a .bat file with the commands you need (I use to run .py script into this) into a FOLDER,
• go in the variable environment setting (type var in the search bar and it will show up)
• in the global settings
  • choose path,
  • then modify,
  • then add the path to your .bat file (without the .bat file)
  • close everything: done.

Open the cmd, write the name of the .bat file and it will work

This is an modified version of Manoj's answer that I use on a project. Just updated to take a class, html attributes and use the TagBuilder.

    public static IHtmlString Image(this HtmlHelper helper, byte[] image, string imgclass, 
                                     object htmlAttributes = null)
    {
        var builder = new TagBuilder("img");
        builder.MergeAttribute("class", imgclass);
        builder.MergeAttributes(new RouteValueDictionary(htmlAttributes));

        var imageString = image != null ? Convert.ToBase64String(image) : "";
        var img = string.Format("data:image/jpg;base64,{0}", imageString);
        builder.MergeAttribute("src", img);

        return MvcHtmlString.Create(builder.ToString(TagRenderMode.SelfClosing));
    }

Which can be used then as follows:

    @Html.Image(Model.Image, "img-cls", new { width="200", height="200" })

This also happened to me on Ubuntu 16.04 using the nvidia-348 package (latest nvidia version on Ubuntu 16.04).

However I could resolve the problem by installing nvidia-390 through the Proprietary GPU Drivers PPA.

So a solution to the described problem on Ubuntu 16.04 is doing this:

• sudo add-apt-repository ppa:graphics-drivers/ppa
• sudo apt-get update
• sudo apt-get install nvidia-390

Note: This guide assumes a clean Ubuntu install. If you have previous drivers installed a reboot migh be needed to reload all the kernel modules.

Find root build.gradle file and add google maven repo inside allprojects tag

repositories {
        mavenLocal()
        mavenCentral()
        maven {                                  // <-- Add this
            url 'https://maven.google.com/' 
            name 'Google'
        }
    } 

It's better to use specific version instead of variable version

compile 'com.android.support:appcompat-v7:27.0.0'

If you're using Android Plugin for Gradle 3.0.0 or latter version

repositories {
      mavenLocal()
      mavenCentral()
      google()        //---> Add this
} 

and inject dependency in this way :

implementation 'com.android.support:appcompat-v7:27.0.0'

If all else fails you can also use

"My text needs a line break here" + System.Environment.NewLine + " This should be a new line"

So, I decided to throw my own solution in the pot. Here is a working fiddle. Note this only runs on very modern browsers.

What it uses

This implementation is very modern - it requires a (very) modern browser and users two new technologies:

• MutationObservers to detect changes in the dom (event listeners are used as well)
• Object.observe to detect changes in the object and notifying the dom. Danger, since this answer has been written O.o has been discussed and decided against by the ECMAScript TC, consider a polyfill.

How it works

• On the element, put a domAttribute:objAttribute mapping - for example bind='textContent:name'
• Read that in the dataBind function. Observe changes to both the element and the object.
• When a change occurs - update the relevant element.

The solution

Here is the dataBind function, note it's just 20 lines of code and could be shorter:

function dataBind(domElement, obj) {    
    var bind = domElement.getAttribute("bind").split(":");
    var domAttr = bind[0].trim(); // the attribute on the DOM element
    var itemAttr = bind[1].trim(); // the attribute the object

    // when the object changes - update the DOM
    Object.observe(obj, function (change) {
        domElement[domAttr] = obj[itemAttr]; 
    });
    // when the dom changes - update the object
    new MutationObserver(updateObj).observe(domElement, { 
        attributes: true,
        childList: true,
        characterData: true
    });
    domElement.addEventListener("keyup", updateObj);
    domElement.addEventListener("click",updateObj);
    function updateObj(){
        obj[itemAttr] = domElement[domAttr];   
    }
    // start the cycle by taking the attribute from the object and updating it.
    domElement[domAttr] = obj[itemAttr]; 
}

Here is some usage:

HTML:

<div id='projection' bind='textContent:name'></div>
<input type='text' id='textView' bind='value:name' />

JavaScript:

var obj = {
    name: "Benjamin"
};
var el = document.getElementById("textView");
dataBind(el, obj);
var field = document.getElementById("projection");
dataBind(field,obj);

Here is a working fiddle. Note that this solution is pretty generic. Object.observe and mutation observer shimming is available.

[textField resignFirstResponder];

Use this

Modern browsers (tested on Chrome, Firefox, Safari) implement some helper functions using the dollar sign $ that are very similar to jQuery (if the website doesn't define something using window.$).

Those utilities are quite useful for selecting elements in the DOM and modifying them.

Docs: Chrome, Firefox

I would use ruby-build with rbenv. The following lines install Ruby 3.0.0 and set it as your default Ruby version:

$ brew update
$ brew install ruby-build
$ brew install rbenv

$ rbenv install 3.0.0
$ rbenv global 3.0.0

The SyntheticEvent interface is generic:

interface SyntheticEvent<T> {
    ...
    currentTarget: EventTarget & T;
    ...
}

(Technically the currentTarget property is on the parent BaseSyntheticEvent type.)

And the currentTarget is an intersection of the generic constraint and EventTarget.
Also, since your events are caused by an input element you should use the ChangeEvent (in definition file, the react docs).

Should be:

update = (e: React.ChangeEvent<HTMLInputElement>): void => {
    this.props.login[e.currentTarget.name] = e.currentTarget.value
}

(Note: This answer originally suggested using React.FormEvent. The discussion in the comments is related to this suggestion, but React.ChangeEvent should be used as shown above.)

For me the problem was an invisible to human eye "?" Left-To-Right Embedding character.
It stuck at the beginning of the string (just before the 'D'), after I copy-pasted the path, from the windows file properties security tab.

var yourJson = System.IO.File.ReadAllText(@"D:\test\json.txt"); // Works
var yourJson = System.IO.File.ReadAllText(@"?D:\test\json.txt"); // Error

So those, identical at first glance, two lines are actually different.

I am not sure that you understand what submit() does...

When you do form1.submit(); the form information is sent to the webserver.

The WebServer will do whatever its supposed to do and return a brand new webpage to the client(usually the same page with something changed).

So, there is no way you can "catch" the return of a form.submit() action.

I think everything that you need is array_key_exists:

if (!array_key_exists('id', $access_data['Privilege'])) {
                $this->Session->setFlash(__('Access Denied! You are not eligible to access this.'), 'flash_custom_success');
                return $this->redirect(array('controller' => 'Dashboard', 'action' => 'index'));
            }

I had the same error on OSX Sierra, but in my case the ~/.android folder was owned by root (from a previous install) I changed the ownership to my User and now it works.

• socket.isConnected() returns always true once the client connects (and even after the disconnect) weird !!
• socket.getInputStream().read()
  • makes the thread wait for input as long as the client is connected and therefore makes your program not do anything - except if you get some input
  • returns -1 if the client disconnected
• socket.getInetAddress().isReachable(int timeout): From isReachable(int timeout)

  Test whether that address is reachable. Best effort is made by the implementation to try to reach the host, but firewalls and server configuration may block requests resulting in a unreachable status while some specific ports may be accessible. A typical implementation will use ICMP ECHO REQUESTs if the privilege can be obtained, otherwise it will try to establish a TCP connection on port 7 (Echo) of the destination host.

When the session expires the data is no longer present, so something like

if (!isset($_SESSION['id'])) {
    header("Location: destination.php");
    exit;
}

will redirect whenever the session is no longer active.

You can set how long the session cookie is alive using session.cookie_lifetime

ini_set("session.cookie_lifetime","3600"); //an hour

EDIT: If you are timing sessions out due to security concern (instead of convenience,) use the accepted answer, as the comments below show, this is controlled by the client and thus not secure. I never thought of this as a security measure.

This is a little function that prints colored text using bash scripting. You may add as many styles as you want, and even print tabs and new lines:

#!/bin/bash

# prints colored text
print_style () {

    if [ "$2" == "info" ] ; then
        COLOR="96m";
    elif [ "$2" == "success" ] ; then
        COLOR="92m";
    elif [ "$2" == "warning" ] ; then
        COLOR="93m";
    elif [ "$2" == "danger" ] ; then
        COLOR="91m";
    else #default color
        COLOR="0m";
    fi

    STARTCOLOR="\e[$COLOR";
    ENDCOLOR="\e[0m";

    printf "$STARTCOLOR%b$ENDCOLOR" "$1";
}

print_style "This is a green text " "success";
print_style "This is a yellow text " "warning";
print_style "This is a light blue with a \t tab " "info";
print_style "This is a red text with a \n new line " "danger";
print_style "This has no color";

You could use a @HostListener decorator. Works with Angular 4 and up.

import { HostListener } from '@angular/core';

@HostListener("window:scroll", []) onWindowScroll() {
    // do some stuff here when the window is scrolled
    const verticalOffset = window.pageYOffset 
          || document.documentElement.scrollTop 
          || document.body.scrollTop || 0;
}

A simpler solution without using filter can be achieved with Object.entries() instead of Object.keys()

const raw = {
  item1: { key: 'sdfd', value:'sdfd' },
  item2: { key: 'sdfd', value:'sdfd' },
  item3: { key: 'sdfd', value:'sdfd' }
};

const allowed = ['item1', 'item3'];

const filtered = Object.entries(raw).reduce((acc,elm)=>{
  const [k,v] = elm
  if (allowed.includes(k)) {
    acc[k] = v 
  }
  return acc
},{})

No, it's not the script, it's the fact that your script is not executed by Python at all. If your script is stored in a file named script.py, you have to execute it as python script.py, otherwise the default shell will execute it and it will bail out at the from keyword. (Incidentally, from is the name of a command line utility which prints names of those who have sent mail to the given username, so that's why it tries to access the mailboxes).

Another possibility is to add the following line to the top of the script:

#!/usr/bin/env python

This will instruct your shell to execute the script via python instead of trying to interpret it on its own.

Great question.

Consider the following example (scroller is a UIScrollView):

float offset = 1000;
[super viewDidLoad];
for (int i=0;i<500; i++) {
    UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(i * 100, 50, 95, 100)] autorelease];
    [label setText:[NSString stringWithFormat:@"label %d",i]];
    [self.scroller addSubview:label];
    [self.scroller setContentSize:CGSizeMake(self.view.frame.size.width * 2 + offset, 0)];
    [self.scroller setContentInset:UIEdgeInsetsMake(0, -offset, 0, 0)];
}

The insets are the ONLY way to force your scroller to have a "window" on the content where you want it. I'm still messing with this sample code, but the idea is there: use the insets to get a "window" on your UIScrollView.

Simpler is better IMO!

Why don't you do this?

public class CourseController : JsonController
{
    public ActionResult ManageCoursesModel()
    {
        return JsonContent(<somedata>);
    }
}

The simple base class controller

public class JsonController : BaseController
{
    protected ContentResult JsonContent(Object data)
    {
        return new ContentResult
        {
            ContentType = "application/json",
             Content = JsonConvert.SerializeObject(data, new JsonSerializerSettings { 
              ContractResolver = new CamelCasePropertyNamesContractResolver() }),
            ContentEncoding = Encoding.UTF8
        };
    }
}

The best tool I found useful and worked every time is code review (with good code reviewers).

Other than code review, I'd first try Page Heap. Page Heap takes a few seconds to set up and with luck it might pinpoint your problem.

If no luck with Page Heap, download Debugging Tools for Windows from Microsoft and learn to use the WinDbg. Sorry couldn't give you more specific help, but debuging multi-threaded heap corruption is more an art than science. Google for "WinDbg heap corruption" and you should find many articles on the subject.

Jasypt provides the org.jasypt.properties.EncryptableProperties class for loading, managing and transparently decrypting encrypted values in .properties files, allowing the mix of both encrypted and not-encrypted values in the same file.

http://www.jasypt.org/encrypting-configuration.html

By using an org.jasypt.properties.EncryptableProperties object, an application would be able to correctly read and use a .properties file like this:

datasource.driver=com.mysql.jdbc.Driver 
datasource.url=jdbc:mysql://localhost/reportsdb 
datasource.username=reportsUser 
datasource.password=ENC(G6N718UuyPE5bHyWKyuLQSm02auQPUtm) 

Note that the database password is encrypted (in fact, any other property could also be encrypted, be it related with database configuration or not).

How do we read this value? like this:

/*
* First, create (or ask some other component for) the adequate encryptor for   
* decrypting the values in our .properties file.   
*/  
StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();     
encryptor.setPassword("jasypt"); // could be got from web, env variable...    
/*   
* Create our EncryptableProperties object and load it the usual way.   
*/  
Properties props = new EncryptableProperties(encryptor);  
props.load(new FileInputStream("/path/to/my/configuration.properties"));

/*   
* To get a non-encrypted value, we just get it with getProperty...   
*/  
String datasourceUsername = props.getProperty("datasource.username");

/*   
* ...and to get an encrypted value, we do exactly the same. Decryption will   
* be transparently performed behind the scenes.   
*/ 
String datasourcePassword = props.getProperty("datasource.password");

 // From now on, datasourcePassword equals "reports_passwd"...

Your assumptions don't seem to be right. After a clear(), the newly added data start from index 0.

var filtered = projects;
foreach (var tag in filteredTags) {
  filtered = filtered.Where(p => p.Tags.Contains(tag))
}

The nice thing with this approach is that you can refine search results incrementally.

make will do this for you. Investigate the -j and -l switches in the man page. I don't think g++ is parallelizable.

C# Xamarin version

    var userDefaults = NSUserDefaults.StandardUserDefaults;
    if (!userDefaults.BoolForKey(FIRST_RUN))
    {
        //TODO: remove keychain items
        userDefaults.SetBool(true, FIRST_RUN);
        userDefaults.Synchronize();
    }

... and to clear records from the keychain (TODO comment above)

it is saved in your Documents and Settings\%user%\Local Settings\Application Data......etc search for a file called user.config there

the location may change however.

echo "<script>
window.location.href='admin/ahm/panel';
alert('There are no fields to generate a report');
</script>";

Try out this way it works...

First assign the window with the new page where the alert box must be displayed then show the alert box.

The most succinct way to do this is:

Get-WmiObject -Class win32_computersystem -Property *

In Swift 3 you can do it like this:

@IBOutlet weak var webview: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Web view load
    let url = URL (string: "http://www.example.com/")
    let request = URLRequest(url: url!)
    webview.loadRequest(request)
}

Remember to add permission at Info.plist, add the following values:

I've had the same error and I solve it with: git merge -s recursive -X theirs origin/master

'joins' just used to join tables and when you called associations on joins then it will again fire query (it mean many query will fire)

lets suppose you have tow model, User and Organisation
User has_many organisations
suppose you have 10 organisation for a user 
@records= User.joins(:organisations).where("organisations.user_id = 1")
QUERY will be 
 select * from users INNER JOIN organisations ON organisations.user_id = users.id where organisations.user_id = 1

it will return all records of organisation related to user
and @records.map{|u|u.organisation.name}
it run QUERY like 
select * from organisations where organisations.id = x then time(hwo many organisation you have)

total number of SQL is 11 in this case

But with 'includes' will eager load the included associations and add them in memory(load all associations on first load) and not fire query again

when you get records with includes like @records= User.includes(:organisations).where("organisations.user_id = 1") then query will be

select * from users INNER JOIN organisations ON organisations.user_id = users.id where organisations.user_id = 1
and 


 select * from organisations where organisations.id IN(IDS of organisation(1, to 10)) if 10 organisation
and when you run this 

@records.map{|u|u.organisation.name} no query will fire

You can start Eclipse in clean mode from the command line:

Add Custom Font in Swift

1. Drag and drop your font in your project.
2. Double check that it is added in Copy Bundle Resource. (Build Phase -> Copy Bundle Resource).
3. In your plist file add "Font Provided by application" and add your fonts with full name.
4. Now use your font like: myLabel.font = UIFont (name: "GILLSANSCE-ROMAN", size: 20)

You can try this simple code with the features of ucwords in PHP.

function ucWords(text) {
    return text.split(' ').map((txt) => (txt.substring(0, 1).toUpperCase() + txt.substring(1, txt.length))).join(' ');
}
ucWords('hello WORLD');

It will keep the Upper Cases unchanged.

For some reason, I have to use

element.find('.fc-event-inner').empty();

to make it work, i guess i'm in day view.

We can use drush command also to check logs drush watchdog-show it will show recent 10 messages.

or if we want to continue showing logs with more information we can user

drush watchdog-show --tail --full.

Please add: CFLAGS="-lrt" and LDFLAGS="-lrt"

case the column isn't string, use astype to convert:

df['col'] = df['col'].astype(str).str[:9]

If you have a job that continues running, you need to search the job and delete it:

kubectl get job --all-namespaces | grep <name>

and

kubectl delete job <job-name>

Because UTF-8 is multibyte and there is no char corresponding to your combination of \xe9 plus following space.

Why should it succeed in both utf-8 and latin-1?

Here how the same sentence should be in utf-8:

>>> o.decode('latin-1').encode("utf-8")
'a test of \xc3\xa9 char'

Soo, your question to convert NaN at ['x',C] to value 10

the answer is..

df['x'].loc['C':]=10
df

alternative code is

df.loc['C', 'x']=10
df

var name = from DataRow dr in tblClassCode.Rows where (long)dr["ID"] == Convert.ToInt32(i) select (int)dr["Name"]).FirstOrDefault().ToString()

I'm not familiar enough with Glide, but it looks like if you know the target size, you can use something like this:

Bitmap theBitmap = Glide.
        with(this).
        load("http://....").
        asBitmap().
        into(100, 100). // Width and height
        get();

It looks like you can pass -1,-1, and get a full size image (purely based on tests, can't see it documented).

Note into(int,int) returns a FutureTarget<Bitmap>, so you have to wrap this in a try-catch block covering ExecutionException and InterruptedException. Here's a more complete example implementation, tested and working:

class SomeActivity extends Activity {

    private Bitmap theBitmap = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // onCreate stuff ...
        final ImageView image = (ImageView) findViewById(R.id.imageView);

        new AsyncTask<Void, Void, Void>() {
            @Override
            protected Void doInBackground(Void... params) {
                Looper.prepare();
                try {
                    theBitmap = Glide.
                        with(SomeActivity.this).
                        load("https://www.google.es/images/srpr/logo11w.png").
                        asBitmap().
                        into(-1,-1).
                        get();
                 } catch (final ExecutionException e) {
                     Log.e(TAG, e.getMessage());
                 } catch (final InterruptedException e) {
                     Log.e(TAG, e.getMessage());
                 }
                 return null;
            }
            @Override
            protected void onPostExecute(Void dummy) {
                if (null != theBitmap) {
                    // The full bitmap should be available here
                    image.setImageBitmap(theBitmap);
                    Log.d(TAG, "Image loaded");
                };
            }
        }.execute();
    }
}

Following Monkeyless' suggestion in the comment below (and this appears to be the official way too), you can use a SimpleTarget, optionally coupled with override(int,int) to simplify the code considerably. However, in this case the exact size must be provided (anything below 1 isn't accepted):

Glide
    .with(getApplicationContext())
    .load("https://www.google.es/images/srpr/logo11w.png")
    .asBitmap()
    .into(new SimpleTarget<Bitmap>(100,100) {
        @Override
        public void onResourceReady(Bitmap resource, GlideAnimation glideAnimation) {
            image.setImageBitmap(resource); // Possibly runOnUiThread()
        }
    });

as suggested by @hennry if you required the same image then use new SimpleTarget<Bitmap>()

you dont have to use open when you are using for loops.

declare
cursor cur_name is  select * from emp;
begin
for cur_rec in cur_name Loop
    dbms_output.put_line(cur_rec.ename);
end loop;
End ;

or

declare
cursor cur_name is  select * from emp;
cur_rec emp%rowtype;
begin
Open cur_name;
Loop
Fetch cur_name into  Cur_rec;
   Exit when cur_name%notfound;
    dbms_output.put_line(cur_rec.ename);
end loop;
Close cur_name;
End ;

You can put the above answers into one line like this. And you don't need to write the function.

    <asp:Button runat="server" ID="btnUserDelete" Text="Delete" CssClass="GreenLightButton"
         OnClick="BtnUserDelete_Click" meta:resourcekey="BtnUserDeleteResource1"
OnClientClick="if ( !confirm('Are you sure you want to delete this user?')) return false;"  />

printStackTrace() tells at what line you are getting error any why are you getting error.

Example:

 java.lang.ArithmeticException: / by zero
    at MinNumber.main(MinNumber.java:8) 

In Javascript (among others), this is simple. It covers attributes and multiple lines:

/<pre[^>]*>([\s\S]*?)<\/pre>/

Use myDialogFragment.setTargetFragment(this, MY_REQUEST_CODE) from the place where you show the dialog, and then when your dialog is finished, from it you can call getTargetFragment().onActivityResult(getTargetRequestCode(), ...), and implement onActivityResult() in the containing fragment.

It seems like an abuse of onActivityResult(), especially as it doesn't involve activities at all. But I've seen it recommended by official google people, and maybe even in the api demos. I think it's what g/setTargetFragment() were added for.

Expanding a bit on the answers from @Guru and @Ronnis, you can hide the sequence and make it look more like an auto-increment using a trigger, and have a procedure that does the insert for you and returns the generated ID as an out parameter.

create table batch(batchid number,
    batchname varchar2(30),
    batchtype char(1),
    source char(1),
    intarea number)
/

create sequence batch_seq start with 1
/

create trigger batch_bi
before insert on batch
for each row
begin
    select batch_seq.nextval into :new.batchid from dual;
end;
/

create procedure insert_batch(v_batchname batch.batchname%TYPE,
    v_batchtype batch.batchtype%TYPE,
    v_source batch.source%TYPE,
    v_intarea batch.intarea%TYPE,
    v_batchid out batch.batchid%TYPE)
as
begin
    insert into batch(batchname, batchtype, source, intarea)
    values(v_batchname, v_batchtype, v_source, v_intarea)
    returning batchid into v_batchid;
end;
/

You can then call the procedure instead of doing a plain insert, e.g. from an anoymous block:

declare
    l_batchid batch.batchid%TYPE;
begin
    insert_batch(v_batchname => 'Batch 1',
        v_batchtype => 'A',
        v_source => 'Z',
        v_intarea => 1,
        v_batchid => l_batchid);
    dbms_output.put_line('Generated id: ' || l_batchid);

    insert_batch(v_batchname => 'Batch 99',
        v_batchtype => 'B',
        v_source => 'Y',
        v_intarea => 9,
        v_batchid => l_batchid);
    dbms_output.put_line('Generated id: ' || l_batchid);
end;
/

Generated id: 1
Generated id: 2

You can make the call without an explicit anonymous block, e.g. from SQL*Plus:

variable l_batchid number;
exec insert_batch('Batch 21', 'C', 'X', 7, :l_batchid);

... and use the bind variable :l_batchid to refer to the generated value afterwards:

print l_batchid;
insert into some_table values(:l_batch_id, ...);

If the browser has a pdf plugin installed it executes the object, if not it uses Google's PDF Viewer to display it as plain HTML:

</object>

I was incorrectly trying to create a default path with:

<IndexRoute component={DefaultComponent} />
<Route path="/default-path" component={DefaultComponent} />

But this creates two different paths that render the same component. Not only is this pointless, but it can cause glitches in your UI, i.e., when you are styling <Link/> elements based on this.history.isActive().

The right way to create a default route (that is not the index route) is to use <IndexRedirect/>:

<IndexRedirect to="/default-path" />
<Route path="/default-path" component={DefaultComponent} />

This is based on react-router 1.0.0. See https://github.com/rackt/react-router/blob/master/modules/IndexRedirect.js.

You can do this using Cygwin’s setup.exe from Windows command line. Example:

cd C:\cygwin64
setup-x86_64 -q -P wget,tar,gawk,bzip2,subversion,vim

For a more convenient installer, you may want to use the apt-cyg package manager. Its syntax is similar to apt-get, which is a plus. For this, follow the above steps and then use Cygwin Bash for the following steps:

wget rawgit.com/transcode-open/apt-cyg/master/apt-cyg
install apt-cyg /bin

Now that apt-cyg is installed. Here are a few examples of installing some packages:

apt-cyg install nano
apt-cyg install git
apt-cyg install ca-certificates

TL;DR

Error #1064 means that MySQL can't understand your command. To fix it:

• Read the error message. It tells you exactly where in your command MySQL got confused.

• Examine your command. If you use a programming language to create your command, use echo, console.log(), or its equivalent to show the entire command so you can see it.

• Check the manual. By comparing against what MySQL expected at that point, the problem is often obvious.

• Check for reserved words. If the error occurred on an object identifier, check that it isn't a reserved word (and, if it is, ensure that it's properly quoted).

1. Aaaagh!! What does #1064 mean?

   Error messages may look like gobbledygook, but they're (often) incredibly informative and provide sufficient detail to pinpoint what went wrong. By understanding exactly what MySQL is telling you, you can arm yourself to fix any problem of this sort in the future.

   As in many programs, MySQL errors are coded according to the type of problem that occurred. Error #1064 is a syntax error.

   • What is this "syntax" of which you speak? Is it witchcraft?

     Whilst "syntax" is a word that many programmers only encounter in the context of computers, it is in fact borrowed from wider linguistics. It refers to sentence structure: i.e. the rules of grammar; or, in other words, the rules that define what constitutes a valid sentence within the language.

     For example, the following English sentence contains a syntax error (because the indefinite article "a" must always precede a noun):

     This sentence contains syntax error a.

   • What does that have to do with MySQL?

     Whenever one issues a command to a computer, one of the very first things that it must do is "parse" that command in order to make sense of it. A "syntax error" means that the parser is unable to understand what is being asked because it does not constitute a valid command within the language: in other words, the command violates the grammar of the programming language.

     It's important to note that the computer must understand the command before it can do anything with it. Because there is a syntax error, MySQL has no idea what one is after and therefore gives up before it even looks at the database and therefore the schema or table contents are not relevant.

2. How do I fix it?

   Obviously, one needs to determine how it is that the command violates MySQL's grammar. This may sound pretty impenetrable, but MySQL is trying really hard to help us here. All we need to do is…

   • Read the message!

     MySQL not only tells us exactly where the parser encountered the syntax error, but also makes a suggestion for fixing it. For example, consider the following SQL command:

     UPDATE my_table WHERE id=101 SET name='foo'
     

     That command yields the following error message:

     ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id=101 SET name='foo'' at line 1

     MySQL is telling us that everything seemed fine up to the word WHERE, but then a problem was encountered. In other words, it wasn't expecting to encounter WHERE at that point.

     Messages that say ...near '' at line... simply mean that the end of command was encountered unexpectedly: that is, something else should appear before the command ends.

   • Examine the actual text of your command!

     Programmers often create SQL commands using a programming language. For example a php program might have a (wrong) line like this:

     $result = $mysqli->query("UPDATE " . $tablename ."SET name='foo' WHERE id=101");
     

     If you write this this in two lines

     $query = "UPDATE " . $tablename ."SET name='foo' WHERE id=101"
     $result = $mysqli->query($query);
     

     then you can add echo $query; or var_dump($query) to see that the query actually says

     UPDATE userSET name='foo' WHERE id=101
     

     Often you'll see your error immediately and be able to fix it.

   • Obey orders!

     MySQL is also recommending that we "check the manual that corresponds to our MySQL version for the right syntax to use". Let's do that.

     I'm using MySQL v5.6, so I'll turn to that version's manual entry for an UPDATE command. The very first thing on the page is the command's grammar (this is true for every command):

     UPDATE [LOW_PRIORITY] [IGNORE] table_reference
         SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
         [WHERE where_condition]
         [ORDER BY ...]
         [LIMIT row_count]
     

     The manual explains how to interpret this syntax under Typographical and Syntax Conventions, but for our purposes it's enough to recognise that: clauses contained within square brackets [ and ] are optional; vertical bars | indicate alternatives; and ellipses ... denote either an omission for brevity, or that the preceding clause may be repeated.

     We already know that the parser believed everything in our command was okay prior to the WHERE keyword, or in other words up to and including the table reference. Looking at the grammar, we see that table_reference must be followed by the SET keyword: whereas in our command it was actually followed by the WHERE keyword. This explains why the parser reports that a problem was encountered at that point.

   A note of reservation

   Of course, this was a simple example. However, by following the two steps outlined above (i.e. observing exactly where in the command the parser found the grammar to be violated and comparing against the manual's description of what was expected at that point), virtually every syntax error can be readily identified.

   I say "virtually all", because there's a small class of problems that aren't quite so easy to spot—and that is where the parser believes that the language element encountered means one thing whereas you intend it to mean another. Take the following example:

   UPDATE my_table SET where='foo'
   

   Again, the parser does not expect to encounter WHERE at this point and so will raise a similar syntax error—but you hadn't intended for that where to be an SQL keyword: you had intended for it to identify a column for updating! However, as documented under Schema Object Names:

   If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it. (Exception: A reserved word that follows a period in a qualified name must be an identifier, so it need not be quoted.) Reserved words are listed at Section 9.3, “Keywords and Reserved Words”.

   [ deletia ]

   The identifier quote character is the backtick (“`”):

   mysql> SELECT * FROM `select` WHERE `select`.id > 100;

   If the ANSI_QUOTES SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks:

   mysql> CREATE TABLE "test" (col INT);
   ERROR 1064: You have an error in your SQL syntax...
   mysql> SET sql_mode='ANSI_QUOTES';
   mysql> CREATE TABLE "test" (col INT);
   Query OK, 0 rows affected (0.00 sec)

The pack syntax you are using here is for an image that is contained as a Resource within your application, not for a loose file in the file system.

You simply want to pass the actual path to the UriSource:

logo.UriSource = new Uri(@"\\myserver\folder1\Customer Data\sample.png");

I know if that can help you a bit.

Here is something I tried to simulate for you.

Checkout the jsFiddle ;)

Created a filter that you also can use in 'ng-repeat'

app.filter('getById', function() {
  return function(input, id) {
    var i=0, len=input.length;
    for (; i<len; i++) {
      if (+input[i].id == +id) {
        return input[i];
      }
    }
    return null;
  }
});

Usage in controller:

app.controller('SomeController', ['$scope', '$filter', function($scope, $filter) {
     $scope.fish = [{category:'freshwater', id:'1', name: 'trout', more:'false'},  {category:'freshwater', id:'2', name:'bass', more:'false'}]

     $scope.showdetails = function(fish_id){
         var found = $filter('getById')($scope.fish, fish_id);
         console.log(found);
         $scope.selected = JSON.stringify(found);
     }
}]);

Method

$user = $stmt->fetch(PDO::FETCH_ASSOC);

returns a dictionary. You can simply get email and password:

$email = $user['email'];
$password = $user['password'];

Other method

The problem is that varargs got introduced in Java5 and unfortunately, Arrays.asList() got overloaded with a vararg version too. So Arrays.asList(spam) is understood by the Java5 compiler as a vararg parameter of int arrays.

This problem is explained in more details in Effective Java 2nd Ed., Chapter 7, Item 42.

To get started with dotnet core, SqlServer and EF core the below DBContextOptionsBuilder would sufice and you do not need to create App.config file. Do not forget to change the sever address and database name in the below code.

protected override void OnConfiguring(DbContextOptionsBuilder options)
        => options.UseSqlServer(@"Server=(localdb)\MSSQLLocalDB;Database=TestDB;Trusted_Connection=True;");

To use the EF core SqlServer provider and compile the above code install the EF SqlServer package

dotnet add package Microsoft.EntityFrameworkCore.SqlServer

After compilation before running the code do the following for the first time

dotnet tool install --global dotnet-ef
dotnet add package Microsoft.EntityFrameworkCore.Design
dotnet ef migrations add InitialCreate
dotnet ef database update

To run the code

dotnet run

Database is a collection of schemas and schema is a collection of tables. But in MySQL they use it the same way.

I thought of Adding these links -

• A brief History of DateTime - By Anthony Moore by BCL team
• Choosing between Datetime and DateTime Offset - by MSDN
• Do not forget SQL server 2008 onwards has a new Datatype as DateTimeOffset
• The .NET Framework includes the DateTime, DateTimeOffset, and TimeZoneInfo types, all of which can be used to build applications that work with dates and times.
• Performing Arithmetic Operations with Dates and Times-MSDN

Coming back to original question , Using Reflector i have explained the difference in code

 public static DateTime Today
    {
      get
      {
        return DateTime.Now.Date;   // It returns the date part of Now

        //Date Property
       // returns same date as this instance, and the time value set to 12:00:00 midnight (00:00:00) 
      }
    }


    private const long TicksPerMillisecond = 10000L;
    private const long TicksPerDay = 864000000000L;
    private const int MillisPerDay = 86400000;

    public DateTime Date
    {
       get
      {
        long internalTicks = this.InternalTicks; // Date this instance is converted to Ticks 
        return new DateTime((ulong) (internalTicks - internalTicks % 864000000000L) | this.InternalKind);  
// Modulo of TicksPerDay is subtracted - which brings the time to Midnight time 
      }
    }


     public static DateTime Now
        {
          get
          {
           /* this is why I guess Jon Skeet is recommending to use  UtcNow as you can see in one of the above comment*/
            DateTime utcNow = DateTime.UtcNow;


            /* After this i guess it is Timezone conversion */
            bool isAmbiguousLocalDst = false;
            long ticks1 = TimeZoneInfo.GetDateTimeNowUtcOffsetFromUtc(utcNow, out isAmbiguousLocalDst).Ticks;
            long ticks2 = utcNow.Ticks + ticks1;
            if (ticks2 > 3155378975999999999L)
              return new DateTime(3155378975999999999L, DateTimeKind.Local);
            if (ticks2 < 0L)
              return new DateTime(0L, DateTimeKind.Local);
            else
              return new DateTime(ticks2, DateTimeKind.Local, isAmbiguousLocalDst);
          }
        }

default is basically const someVariableName

You don't need a named identifier because it's the default export for the file and you can name it whatever you want when you import it, so default is just condensing the variable assignment into a single keyword.

functools.reduce and pd.concat are good solutions but in term of execution time pd.concat is the best.

from functools import reduce
import pandas as pd

dfs = [df1, df2, df3, ...]
nan_value = 0

# solution 1 (fast)
result_1 = pd.concat(dfs, join='outer', axis=1).fillna(nan_value)

# solution 2
result_2 = reduce(lambda df_left,df_right: pd.merge(df_left, df_right, 
                                              left_index=True, right_index=True, 
                                              how='outer'), 
                  dfs).fillna(nan_value)

Late to the party, but another easy way of comparing NSDate objects is to convert them into primitive types which allows for easy use of '>' '<' '==' etc

eg.

if ([dateA timeIntervalSinceReferenceDate] > [dateB timeIntervalSinceReferenceDate]) {
    //do stuff
}

timeIntervalSinceReferenceDate converts the date into seconds since the reference date (1 January 2001, GMT). As timeIntervalSinceReferenceDate returns a NSTimeInterval (which is a double typedef), we can use primitive comparators.

As of January 31, 2013 Github markdown supports relative links to files.

[a relative link](markdown_file.md)

However, there are a few deficiencies that have been discussed in this comment thread.

As an alternative, you can use Gitdown to construct full URLs to the repository and even make them branch aware, e.g.

{"gitdown": "gitinfo", "name": "url"} // https://github.com/gajus/gitdown
{"gitdown": "gitinfo", "name": "branch"} // master

Gitdown is a GitHub markdown preprocessor. It streamlines common tasks associated with maintaining a documentation page for a GitHub repository, e.g. generating table of contents, including variables, generating URLs and getting information about the repository itself at the time of processing the input. Gitdown seamlessly integrates with your building scripts.

Just 2 step for fix this error.

1. Remove old certificate from developer.apple.com
2. Create new certificate from Xcode or developer.apple.com

My problem has been solved (I am using Xcode 9.4.1).

Please check, Xcode created new certificate.

Try this solution: https://stackoverflow.com/a/46274919/907576 :

with @BeforeAllMethods/@AfterAllMethods annotation you could execute any method in Test class in an instance context, where all injected values are available.

1. Set up your routes to accept data

{
    path: 'some-route',
    loadChildren: 
      () => import(
        './some-component/some-component.module'
      ).then(
        m => m.SomeComponentModule
      ),
    data: {
      key: 'value',
      ...
    },
}

2. Navigate to route:

From HTML:

<a [routerLink]=['/some-component', { key: 'value', ... }> ... </a>

Or from Typescript:

import {Router} from '@angular/router';

...

 this.router.navigate(
    [
       '/some-component',
       {
          key: 'value',
          ...
       }
    ]
 );

3. Get data from route

import {ActivatedRoute} from '@angular/router';

...

this.value = this.route.snapshot.params['key'];

You need to use a regular expression, so that you can specify the global (g) flag:

var s = 'some+multi+word+string'.replace(/\+/g, ' ');

(I removed the $() around the string, as replace is not a jQuery method, so that won't work at all.)

If the problem is that you don't have access to SQL Server and now you are using mixed mode to enable sa or grant an account admin privileges, then it is far easier just to uninstall SQL Server and reinstall.

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

I realize I am a little late here, (5 years or so), but I think there is a better answer than the accepted one as follows:

$("#addComment").click(function() {
    if(typeof TinyMCE === "undefined") {
        $.ajax({
            url: "tinymce.js",
            dataType: "script",
            cache: true,
            success: function() {
                TinyMCE.init();
            }
        });
    }
});

The getScript() function actually prevents browser caching. If you run a trace you will see the script is loaded with a URL that includes a timestamp parameter:

http://www.yoursite.com/js/tinymce.js?_=1399055841840

If a user clicks the #addComment link multiple times, tinymce.js will be re-loaded from a differently timestampped URL. This defeats the purpose of browser caching.

===

Alternatively, in the getScript() documentation there is a some sample code that demonstrates how to enable caching by creating a custom cachedScript() function as follows:

jQuery.cachedScript = function( url, options ) {

    // Allow user to set any option except for dataType, cache, and url
    options = $.extend( options || {}, {
        dataType: "script",
        cache: true,
        url: url
    });

    // Use $.ajax() since it is more flexible than $.getScript
    // Return the jqXHR object so we can chain callbacks
    return jQuery.ajax( options );
};

// Usage
$.cachedScript( "ajax/test.js" ).done(function( script, textStatus ) {
    console.log( textStatus );
});

===

Or, if you want to disable caching globally, you can do so using ajaxSetup() as follows:

$.ajaxSetup({
    cache: true
});

Try either

• sudo apt-get install php-zip or
• sudo apt-get install php5.6-zip

Then, you might have to restart your web server.

• sudo service apache2 restart or
• sudo service nginx restart

If you are installing on centos or fedora OS then use yum in place of apt-get. example:-

sudo yum install php-zip or sudo yum install php5.6-zip and sudo service httpd restart

Another, and more streamlined, approach to deserializing a camel-cased JSON string to a pascal-cased POCO object is to use the CamelCasePropertyNamesContractResolver.

It's part of the Newtonsoft.Json.Serialization namespace. This approach assumes that the only difference between the JSON object and the POCO lies in the casing of the property names. If the property names are spelled differently, then you'll need to resort to using JsonProperty attributes to map property names.

using Newtonsoft.Json; 
using Newtonsoft.Json.Serialization;

. . .

private User LoadUserFromJson(string response) 
{
    JsonSerializerSettings serSettings = new JsonSerializerSettings();
    serSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
    User outObject = JsonConvert.DeserializeObject<User>(jsonValue, serSettings);

    return outObject; 
}

You can add it manually in the .gitconfig file

[alias]
    cm = "commit -m"

Or using the script:

git config --global alias.cm "commit -m"

Here is a screenshot of the .gitconfig

If you want the powershell errormessage for a cmdlet suppressed, but still want to catch the error, use "-erroraction 'silentlyStop'"

The following is the one that I'm using to generate a vertical gradient from completely opaque (top) to 20% in transparency (bottom) for the same color:

background: linear-gradient(to bottom, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* W3C, IE10+, FF16+, Chrome26+, Opera12+, Safari7+ */
background: -o-linear-gradient(top, rgba(0, 64, 122, 1) 0%, rgba(0, 64, 122, 0.8) 100%); /* Opera 11.10+ */
background: -moz-linear-gradient(top, rgba(0, 64, 122, 1) 0%, rgba(0, 64, 122, 0.8) 100%); /* FF3.6-15 */
background: -webkit-linear-gradient(top, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* Chrome10-25,Safari5.1-6 */
background: -ms-linear-gradient(top, rgba(0, 64, 122, 1) 0%,rgba(0, 64, 122, 0.8) 100%); /* IE10+ */
-ms-filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00407a', endColorstr='#cc00407a',GradientType=0 ); /* IE8 */
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#00407a', endColorstr='#cc00407a',GradientType=0 ); /* IE 5.5 - 9 */

obj = {'a':'c','b':'d'}

You can try:

[index for (index in obj)] 

this will return:

['a','b']

to get the list of keys or

[obj[index] for (index in obj)]

to get the values

Following is my project structure:

ProjectFolder:
 - project:
     - __init__.py
     - item.py
 - tests:
     - test_item.py

I found it better to import in the setUp() method:

import unittest
import sys    

class ItemTest(unittest.TestCase):

    def setUp(self):
        sys.path.insert(0, "../project")
        from project import item
        # further setup using this import

    def test_item_props(self):
        # do my assertions

if __name__ == "__main__":
    unittest.main()

You can have a look at this library: https://github.com/mozilla/pdf.js it renders PDF document in a Web/HTML page

Also you can use Flash to embed the document into any HTML page like that:

<object data="your_file.pdf#view=Fit" type="application/pdf" width="100%" height="850">
    <p>
        It appears your Web browser is not configured to display PDF files. No worries, just <a href="your_file.pdf">click here to download the PDF file.</a>
    </p>
</object>

I prefer using standard converters:

#include <codecvt>

std::string s = "Hi";
std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> converter;
std::wstring wide = converter.from_bytes(s);
LPCWSTR result = wide.c_str();

Please find more details in this answer: https://stackoverflow.com/a/18597384/592651

Update 12/21/2020 : My answer was commented on by @Andreas H . I thought his comment is valuable, so I updated my answer accordingly:

1. codecvt_utf8_utf16 is deprecated in C++17.
2. Also the code implies that source encoding is UTF-8 which it usually isn't.
3. In C++20 there is a separate type std::u8string for UTF-8 because of that.

But it worked for me because I am still using an old version of C++ and it happened that my source encoding was UTF-8 .

String joined = 
                Stream.of(isRead?"read":"", isFlagged?"flagged":"", isActionRequired?"action":"", isHide?"hide":"")
                      .filter(s -> s != null && !s.isEmpty())
                      .collect(Collectors.joining(","));

Assuming you are looking out in Winform, there is a SelectedIndexChanged event for the tab

Now in it you could check for your specific tab and proceed with the logic

private void tab1_SelectedIndexChanged(object sender, EventArgs e)
{
     if (tab1.SelectedTab == tab1.TabPages["tabname"])//your specific tabname
     {
         // your stuff
     }
}

another solution is catching onClick event and for aggregate data to js function you can

.hmtl.erb

<%= link_to "Action", 'javascript:;', class: 'my-class', data: { 'array' => %w(foo bar) } %>

.js

// handle my-class click
$('a.my-class').on('click', function () {
  var link = $(this);
  var array = link.data('array');
});
