What about com.sun.tools.javac.util.Pair?

Be careful while using these notations: For eg. if we want to access a function present in the parent of a window. In IE :

window['parent']['func']

is not equivalent to

window.['parent.func']

We may either use:

window['parent']['func'] 

or

window.parent.func 

to access it

You need to do the subselect based on a column name, not *.

For example, if you had an id field common to both tables, you could do:

SELECT * FROM Table1 WHERE id NOT IN (SELECT id FROM Table2)

Refer to the MySQL subquery syntax for more examples.

This is more predictable then "line-height"

.loginBtn {_x000D_
    background:url(images/loginBtn-center.jpg) repeat-x;_x000D_
    width:175px;_x000D_
    height:65px;_x000D_
    margin:20px auto;_x000D_
    border-radius:10px;_x000D_
    -webkit-border-radius:10px;_x000D_
    box-shadow:0 1px 2px #5e5d5b;_x000D_
}_x000D_
_x000D_
.loginBtn span {_x000D_
    display: block;_x000D_
    padding-top: 22px;_x000D_
    text-align: center;_x000D_
    line-height: 1em;_x000D_
}

<div id="loginBtn" class="loginBtn"><span>Log in</span></div>

EDIT (2018): use flexbox

.loginBtn {
    display: flex;
    align-items: center;
    justify-content: center;
}

I know the question was about postgresql version 8 but I wrote this simple way here for people who want to get sequences in version 10 and upper

you can use the bellow query

You can use PdfBox from Apache which is simple to use and has good performance.

Here is an example of extracting text from a PDF file (you can read more here) :

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\Invoice.pdf");  // The PDF file from where you would like to extract
         File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
         PDFTextStripper stripper = new PDFTextStripper();
         wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
         stripper.writeText(pd, wr);
         if (pd != null) {
             pd.close();
         }
        // I use close() to flush the stream.
        wr.close();
 } catch (Exception e){
         e.printStackTrace();
        } 
     }
}

UPDATE:

You can get the text using PDFTextStripper:

PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created

I solved it for myself with Window->Preferences->Android and SDK Location: path to adt\sdk e.g. C:\adt\sdk

You can not do this directly. In standard WebForms JavaScript is interpreted by browser and C# by server. What you can do to call a method from server using JavaScript is.

• Use WebMethod as attribute in target methods.
• Add ScriptManager setting EnablePageMethods as true.
• Add JavaScript code to call the methods through the object PageMethods.

Like this:

Step 1

public partial class Products : System.Web.UI.Page 
{ 
    [System.Web.Services.WebMethod()] 
    [System.Web.Script.Services.ScriptMethod()] 
    public static List<Product> GetProducts(int cateogryID) 
    {
        // Put your logic here to get the Product list 
    }

Step 2: Adding a ScriptManager on the Page

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true" />

Step 3: Calling the method using JavaScript

function GetProductsByCategoryID(categoryID)
{
    PageMethods.GetProducts(categoryID, OnGetProductsComplete);
}

Take a look at this link.

To call a JavaScript function from server you can use RegisterStartupScript:

ClientScript.RegisterStartupScript(GetType(),"id","callMyJSFunction()",true);

I have faced similar issue and none of the above solution worked as I was in protected network.

To overcome this, I have installed "Fiddler" tool from Telerik, after installation start Fiddler and start installation of Protractor again.

Hope this will resolve your issue.

Thanks.

I will share my solution which worked for me in a create-react-app project:

in the same images folder include a js file which exports all the images, and in components where you need the image import that image and use it :), Yaaah thats it, lets see in detail

folder structure with JS file

// js file in images folder
export const missing = require('./missingposters.png');
export const poster1 = require('./poster1.jpg');
export const poster2 = require('./poster2.jpg');
export const poster3 = require('./poster3.jpg');
export const poster4 = require('./poster4.jpg');

you can import in you component: import {missing , poster1, poster2, poster3, poster4} from '../../assets/indexImages';

you can now use this as src to image tag.

Happy coding!

ADD go /usr/local/

will copy the contents of your local go directory in the /usr/local/ directory of your docker image.

To copy the go directory itself in /usr/local/ use:

ADD go /usr/local/go

or

COPY go /usr/local/go

You don't. The closest thing you can do is working with Maps to simulate it, or defining your own Objects to deal with.

Instead of step="any", which allows for any number of decimal places, use step=".01", which allows up to two decimal places.

More details in the spec: https://www.w3.org/TR/html/sec-forms.html#the-step-attribute

Subtract from another date object

var d = new Date();

d.setHours(d.getHours() - 2);

• Complete reference list for Date object

You also may use str.len() to count length of element in the column

data['name of column'].str.len() 

The tools sed or tr will do this for you by swapping the whitespace for nothing

sed 's/ //g'

tr -d ' '

Example:

$ echo "   3918912k " | sed 's/ //g'
3918912k

From back side with Spring Boot I've used custom BasicAuthenticationEntryPoint:

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.cors().and().authorizeRequests()
            ...
            .antMatchers(PUBLIC_AUTH).permitAll()
            .and().httpBasic()
//    https://www.baeldung.com/spring-security-basic-authentication
            .authenticationEntryPoint(authBasicAuthenticationEntryPoint())
            ...

@Bean
public BasicAuthenticationEntryPoint authBasicAuthenticationEntryPoint() {
    return new BasicAuthenticationEntryPoint() {
        {
            setRealmName("pirsApp");
        }

        @Override
        public void commence
                (HttpServletRequest request, HttpServletResponse response, AuthenticationException authEx)
                throws IOException, ServletException {
            if (request.getRequestURI().equals(PUBLIC_AUTH)) {
                response.sendError(HttpStatus.PRECONDITION_FAILED.value(), "Wrong credentials");
            } else {
                super.commence(request, response, authEx);
            }
        }
    };
}

Update:

Separate the event and property bindings:

<select [ngModel]="selectedItem" (ngModelChange)="onChange($event)">

onChange(newValue) {
    console.log(newValue);
    this.selectedItem = newValue;  // don't forget to update the model here
    // ... do other stuff here ...
}

You could also use

<select [(ngModel)]="selectedItem" (ngModelChange)="onChange($event)">

and then you wouldn't have to update the model in the event handler, but I believe this causes two events to fire, so it is probably less efficient.

Old answer, before they fixed a bug in beta.1:

Create a local template variable and attach a (change) event:

<select [(ngModel)]="selectedItem" #item (change)="onChange(item.value)">

Some extend functions in third party libraries are more complex than others. Knockout.js for instance contains a minimally simple one that doesn't have some of the checks that jQuery's does:

function extend(target, source) {
    if (source) {
        for(var prop in source) {
            if(source.hasOwnProperty(prop)) {
                target[prop] = source[prop];
            }
        }
    }
    return target;
}

filter_by uses keyword arguments, whereas filter allows pythonic filtering arguments like filter(User.name=="john")

Do this:

I created a derived class to have a more self-documented instruction instead of $conn=null;.

class CMyPDO extends PDO {
    public function __construct($dsn, $username = null, $password = null, array $options = null) {
        parent::__construct($dsn, $username, $password, $options);
    }

    static function getNewConnection() {
        $conn=null;
        try {
            $conn = new CMyPDO("mysql:host=$host;dbname=$dbname",$user,$pass);
        }
        catch (PDOException $exc) {
            echo $exc->getMessage();
        }
        return $conn;
    }

    static function closeConnection(&$conn) {
        $conn=null;
    }
}

So I can call my code between:

$conn=CMyPDO::getNewConnection();
// my code
CMyPDO::closeConnection($conn);

I made this implementation in kotlin I thing is not very efficient but works ivIsSelected is a ImageView that represent in my case a check mark

var selectedItems = mutableListOf<Int>(-1)

override fun onBindViewHolder(holder: ContactViewHolder, position: Int) {
    // holder.setData(ContactViewModel, position)  // I'm passing this to the ViewHolder
    holder.itemView.setBackgroundColor(Color.WHITE)   
    holder.itemView.ivIsSelected.visibility = INVISIBLE
    selectedItems.forEach {
        if (it == position) {
            holder.itemView.setBackgroundColor(Color.argb(45, 0, 255, 43))
            holder.itemView.ivIsSelected.visibility = VISIBLE
        }
    }

    holder.itemView.setOnClickListener { it ->
        it.setBackgroundColor(Color.BLUE)  
        selectedItems.add(position)
        selectedItems.forEach { selectedItem ->  // this forEach is required to refresh all the list
            notifyItemChanged(selectedItem)

I use the below query for tracing application activity on a SQL server that does not have trace profiler enabled. The method uses Query Store (SQL Server 2016+) instead of the DMV's. This gives better ability to look into historical data, as well as faster lookups. It is very efficient to capture short-running queries that can't be captured by sp_who/sp_whoisactive.

    Run full script (F5) -> Interact with UI -> Run full script again (F5)

For Safari versions <5.1 the css3 property background-size doesn't work. In such cases you need webkit.

So you need to use -webkit-background-size attribute to specify the background-size.

Hence use -webkit-background-size:cover.

Reference-Safari versions using webkit

You can simply use

document.getElementById("elementID").outerHTML="";

It works in all browsers, even on Internet Explorer.

I believe the easiest way to understand the difference is to visualise how threads and processes execute their jobs.

Threads are running in parallel, in a shared memory space (of the process that created them):

Thread 1              Thread 2              Thread 3
   | 
   | 
   |
                         |
                         |
                                               |
                                               |
                                               |
   |
                         |
                         | 
                         |            
Complete             Complete              Complete

Note: The above can be interpreted as a process (i.e. one process with 3 threads)

Processes are running in parallel and concurrently:

Process 1              Process 2              Process 3
    |                      |                      |
    |                      |                      |

Use --build-arg in lower case environment variable:

docker build --build-arg http_proxy=http://proxy:port/ --build-arg https_proxy=http://proxy:port/ --build-arg ftp_proxy=http://proxy:port --build-arg no_proxy=localhost,127.0.0.1,company.com -q=false .

Ok, if it doesn't matter which value in the non-duplicated column you select, this should be pretty easy:

dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))
> dat[!duplicated(dat[,c('id','id2')]),]
  id id2 somevalue
1  1   1         x
3  3   4         z

Inside the duplicated call, I'm simply passing only those columns from dat that I don't want duplicates of. This code will automatically always select the first of any ambiguous values. (In this case, x.)

If you need to get all td's inside tr without defining id for them, you can use the code below :

var items = new Array();

$('#TABLE_ID td:nth-child(1)').each(function () {
      items.push($(this).html());
});

The code above will add all first cells inside the Table into an Array variable.

you can change nth-child(1) which means the first cell to any cell number you need.

hope this code helps you.

The String "false" is actually considered a "TRUE" value by PHP. The documentation says:

To explicitly convert a value to boolean, use the (bool) or (boolean) casts. However, in most cases the cast is unnecessary, since a value will be automatically converted if an operator, function or control structure requires a boolean argument.

See also Type Juggling.

When converting to boolean, the following values are considered FALSE:

• the boolean FALSE itself

• the integer 0 (zero)

• the float 0.0 (zero)

• the empty string, and the string "0"

• an array with zero elements

• an object with zero member variables (PHP 4 only)

• the special type NULL (including unset variables)

• SimpleXML objects created from empty tags

Every other value is considered TRUE (including any resource).

so if you do:

$bool = (boolean)"False";

or

$test = "false";
$bool = settype($test, 'boolean');

in both cases $bool will be TRUE. So you have to do it manually, like GordonM suggests.

I need to do this frequently, so I use this:

var loadJS = function(url, implementationCode, location){
    //url is URL of external file, implementationCode is the code
    //to be called from the file, location is the location to 
    //insert the <script> element

    var scriptTag = document.createElement('script');
    scriptTag.src = url;

    scriptTag.onload = implementationCode;
    scriptTag.onreadystatechange = implementationCode;

    location.appendChild(scriptTag);
};
var yourCodeToBeCalled = function(){
//your code goes here
}
loadJS('yourcode.js', yourCodeToBeCalled, document.body);

For more information, see this site How do I include a JavaScript file in another JavaScript file?, which is the source of my function idea.

one line function:

function type(obj) {
    return Object.prototype.toString.call(obj).replace(/^\[object (.+)\]$/,"$1").toLowerCase()
}

this give the same result as jQuery.type()

You need to point to the directory instead. You must not specify the dockerfile.

docker build -t ubuntu-test:latest . does work.

docker build -t ubuntu-test:latest ./Dockerfile does not work.

var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?foo=bar';
window.history.pushState({path:newurl},'',newurl);

UPDATE

Thanks for all the upvotes everyone, but I don't think my answer below is the best way to write enums in JavaScript anymore. See my blog post for more details: Enums in JavaScript.

Alerting the name is already possible:

if (currentColor == my.namespace.ColorEnum.RED) {
   // alert name of currentColor (RED: 0)
   var col = my.namespace.ColorEnum;
   for (var name in col) {
     if (col[name] == col.RED)
       alert(name);
   }
}

Alternatively, you could make the values objects, so you can have the cake and eat it too:

var SIZE = {
  SMALL : {value: 0, name: "Small", code: "S"}, 
  MEDIUM: {value: 1, name: "Medium", code: "M"}, 
  LARGE : {value: 2, name: "Large", code: "L"}
};

var currentSize = SIZE.MEDIUM;
if (currentSize == SIZE.MEDIUM) {
  // this alerts: "1: Medium"
  alert(currentSize.value + ": " + currentSize.name);
}

In JavaScript, as it is a dynamic language, it is even possible to add enum values to the set later:

// Add EXTRALARGE size
SIZE.EXTRALARGE = {value: 3, name: "Extra Large", code: "XL"};

Remember, the fields of the enum (value, name and code in this example) are not needed for the identity check and are only there for convenience. Also the name of the size property itself does not need to be hard coded, but can also be set dynamically. So supposing you only know the name for your new enum value, you can still add it without problems:

// Add 'Extra Large' size, only knowing it's name
var name = "Extra Large";
SIZE[name] = {value: -1, name: name, code: "?"};

Of course this means that some assumptions can no longer be made (that value represents the correct order for the size for example).

Remember, in JavaScript an object is just like a map or hash table. A set of name-value pairs. You can loop through them or otherwise manipulate them without knowing much about them in advance.

Example

for (var sz in SIZE) {
  // sz will be the names of the objects in SIZE, so
  // 'SMALL', 'MEDIUM', 'LARGE', 'EXTRALARGE'
  var size = SIZE[sz]; // Get the object mapped to the name in sz
  for (var prop in size) {
    // Get all the properties of the size object, iterates over
    // 'value', 'name' and 'code'. You can inspect everything this way.        
  }
} 

And by the way, if you are interested in namespaces, you may want to have a look at my solution for simple but powerful namespace and dependency management for JavaScript: Packages JS

You're trying to put a text node inside an input element.

Input elements are empty and can't have children.

...

feat: Summarize changes in around 50 characters or less

More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. In some contexts, the first line is treated as the
subject of the commit and the rest of the text as the body. The
blank line separating the summary from the body is critical (unless
you omit the body entirely); various tools like `log`, `shortlog`
and `rebase` can get confused if you run the two together.

Explain the problem that this commit is solving. Focus on why you
are making this change as opposed to how (the code explains that).
Are there side effects or other unintuitive consequenses of this
change? Here's the place to explain them.

Further paragraphs come after blank lines.

 - Bullet points are okay, too

 - Typically a hyphen or asterisk is used for the bullet, preceded
   by a single space, with blank lines in between, but conventions
   vary here

If you use an issue tracker, put references to them at the bottom,
like this:

Resolves: #123
See also: #456, #789

You can also reference the repositories:

githubuser/repository#issue_number

Two options - the first, as you said in your own answer, is setting the environment variable ANSIBLE_HOST_KEY_CHECKING to False.

The second way to set it is to put it in an ansible.cfg file, and that's a really useful option because you can either set that globally (at system or user level, in /etc/ansible/ansible.cfg or ~/.ansible.cfg), or in an config file in the same directory as the playbook you are running.

To do that, make an ansible.cfg file in one of those locations, and include this:

[defaults]
host_key_checking = False

You can also set a lot of other handy defaults there, like whether or not to gather facts at the start of a play, whether to merge hashes declared in multiple places or replace one with another, and so on. There's a whole big list of options here in the Ansible docs.

Edit: a note on security.

SSH host key validation is a meaningful security layer for persistent hosts - if you are connecting to the same machine many times, it's valuable to accept the host key locally.

For longer-lived EC2 instances, it would make sense to accept the host key with a task run only once on initial creation of the instance:

  - name: Write the new ec2 instance host key to known hosts
    connection: local
    shell: "ssh-keyscan -H {{ inventory_hostname }} >> ~/.ssh/known_hosts"

There's no security value for checking host keys on instances that you stand up dynamically and remove right after playbook execution, but there is security value in checking host keys for persistent machines. So you should manage host key checking differently per logical environment.

• Leave checking enabled by default (in ~/.ansible.cfg)
• Disable host key checking in the working directory for playbooks you run against ephemeral instances (./ansible.cfg alongside the playbook for unit tests against vagrant VMs, automation for short-lived ec2 instances)

My problem was that I spelt one of the libraries wrongly when installing with pip3, which ended up all the other downloaded libaries in the same command not being installed. Just run pip3 install on them again and they should be installed from their cache.

Steps to install curl in windows

Install cURL on Windows

There are 4 steps to follow to get cURL installed on Windows.

Step 1 and Step 2 is to install SSL library. Step 3 is to install cURL. Step 4 is to install a recent certificate

Step One: Install Visual C++ 2008 Redistributables

From https://www.microsoft.com/en-za/download/details.aspx?id=29 For 64bit systems Visual C++ 2008 Redistributables (x64) For 32bit systems Visual C++ 2008 Redistributables (x32)

Step Two: Install Win(32/64) OpenSSL v1.0.0k Light

From http://www.shininglightpro.com/products/Win32OpenSSL.html For 64bit systems Win64 OpenSSL v1.0.0k Light For 32bit systems Win32 OpenSSL v1.0.0k Light

Step Three: Install cURL

Depending on if your system is 32 or 64 bit, download the corresponding** curl.exe.** For example, go to the Win64 - Generic section and download the Win64 binary with SSL support (the one where SSL is not crossed out). Visit http://curl.haxx.se/download.html

Copy curl.exe to C:\Windows\System32

Step Four: Install Recent Certificates

Do not skip this step. Download a recent copy of valid CERT files from https://curl.haxx.se/ca/cacert.pem Copy it to the same folder as you placed curl.exe (C:\Windows\System32) and rename it as curl-ca-bundle.crt

If you have already installed curl or after doing the above steps, add the directory where it's installed to the windows path:

1 - From the Desktop, right-click My Computer and click Properties.
2 - Click Advanced System Settings .
3 - In the System Properties window click the Environment Variables button.
4 - Select Path and click Edit.
5 - Append ;c:\path to curl directory at the end.
5 - Click OK.
6 - Close and re-open the command prompt

It's worth noting that since $.when expects all of the ajax requests as sequential arguments (not an array) you'll commonly see $.when used with .apply() like so:

// Save all requests in an array of jqXHR objects
var requests = arrayOfThings.map(function(thing) {
    return $.ajax({
        method: 'GET',
        url: 'thing/' + thing.id
    });
});

$.when.apply(this, requests).then(function(resp1, resp2/*, ... */) {
    // Each argument is an array with the following structure: [ data, statusText, jqXHR ]
    var responseArgsArray = Array.prototype.slice.call(this, arguments);

});

Using the Spread syntax, you can now write this code like so:

$.when(...requests).then((...responses) => {
    // do something with responses
})

This is because $.when accepts args like this

$.when(ajaxRequest1, ajaxRequest2, ajaxRequest3);

And not like this:

$.when([ajaxRequest1, ajaxRequest2, ajaxRequest3]);

A crude way would be to call dumpbin with the headers option from the Visual Studio tools on each DLL and look for the appropriate output:

dumpbin /headers my32bit.dll

PE signature found

File Type: DLL

FILE HEADER VALUES
             14C machine (x86)
               1 number of sections
        45499E0A time date stamp Thu Nov 02 03:28:10 2006
               0 file pointer to symbol table
               0 number of symbols
              E0 size of optional header
            2102 characteristics
                   Executable
                   32 bit word machine
                   DLL

OPTIONAL HEADER VALUES
             10B magic # (PE32)

You can see a couple clues in that output that it is a 32 bit DLL, including the 14C value that Paul mentions. Should be easy to look for in a script.

If you are using BookId as an combined primary key, then remember to change your interface from:

public interface QueuedBookRepo extends JpaRepository<QueuedBook, Long> {

to:

public interface QueuedBookRepo extends JpaRepository<QueuedBook, BookId> {

And change the annotation @Embedded to @EmbeddedId, in your QueuedBook class like this:

public class QueuedBook implements Serializable {

@EmbeddedId
@NotNull
private BookId bookId;

...

To bring the existing answers together with an important clarification:

As stated, the problem with NAME=sam echo "$NAME" is that $NAME gets expanded by the current shell before assignment NAME=sam takes effect.

Solutions that preserve the original semantics (of the (ineffective) solution attempt NAME=sam echo "$NAME"):

Use either eval^[1] (as in the question itself), or printenv (as added by Aaron McDaid to heemayl's answer), or bash -c (from Ljm Dullaart's answer), in descending order of efficiency:

NAME=sam eval 'echo "$NAME"'  # use `eval` only if you fully control the command string
NAME=sam printenv NAME
NAME=sam bash -c 'echo "$NAME"'

^{printenv is not a POSIX utility, but it is available on both Linux and macOS/BSD.}

What this style of invocation (<var>=<name> cmd ...) does is to define NAME:

• as an environment variable
• that is only defined for the command being invoked.

In other words: NAME only exists for the command being invoked, and has no effect on the current shell (if no variable named NAME existed before, there will be none after; a preexisting NAME variable remains unchanged).

POSIX defines the rules for this kind of invocation in its Command Search and Execution chapter.

The following solutions work very differently (from heemayl's answer):

NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"

While they produce the same output, they instead define:

• a shell variable NAME (only) rather than an environment variable
  • if echo were a command that relied on environment variable NAME, it wouldn't be defined (or potentially defined differently from earlier).
• that lives on after the command.

Note that every environment variable is also exposed as a shell variable, but the inverse is not true: shell variables are only visible to the current shell and its subshells, but not to child processes, such as external utilities and (non-sourced) scripts (unless they're marked as environment variables with export or declare -x).

^{[1] Technically, bash is in violation of POSIX here (as is zsh): Since eval is a special shell built-in, the preceding NAME=sam assignment should cause the the variable $NAME to remain in scope after the command finishes, but that's not what happens.
However, when you run bash in POSIX compatibility mode, it is compliant.
dash and ksh are always compliant.
The exact rules are complicated, and some aspects are left up to the implementations to decide; again, see Command Search and Execution.
Also, the usual disclaimer applies: Use eval only on input you fully control or implicitly trust.}

Try to encapsulate the ajax call into a function and set the async option to false. Note that this option is deprecated since jQuery 1.8.

function foo() {
    var myajax = $.ajax({
        type: "POST",
        url: "CHService.asmx/SavePurpose",
        dataType: "text",
        data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
        contentType: "application/json; charset=utf-8",
        async: false, //add this
    });
    return myajax.responseText;
}

You can do this also:

$.ajax({
    type: "POST",
    url: "CHService.asmx/SavePurpose",
    dataType: "text",
    data: JSON.stringify({ Vid: Vid, PurpId: PurId }),
    contentType: "application/json; charset=utf-8",
    async: false, //add this
}).done(function ( data ) {
        Success = true;
}).fail(function ( data ) {
       Success = false;
});

Put your prompt in the 1st option and disable it:

<selection>
    <option disabled selected>”Select a language”</option>
    <option>English</option>
    <option>Spanish</option>
</selection>

The first option will automatically be the selected default (what you see first when you look at the drop-down) but adding the selected attribute is more clear and actually needed when the first field is a disabled field.

The disabled attribute will make the option be un-selectable/grayed out.

Other answers suggest setting disabled=“disabled” but that’s only necessary if you need to parse as XHTML, which is basically a more strict version of HTML. disabled on it’s on is enough for standard HTML.

If you want to make the selection “required” (without accepting the “Select a language” option as an accepted answer):

Add the required attribute to selection and set the first option’s value to the empty string ””.

<selection required>
    <option disabled value=“”>Select a language</option>
    <option>English</option>
    <option>Spanish</option>
</selection>

In angular 2 we don't have pre-defined filter and order by as it was with AngularJs, we need to create it for our requirements. It is time killing but we need to do it, (see No FilterPipe or OrderByPipe). In this article we are going to see how we can create filter called pipe in angular 2 and sorting feature called Order By. Let's use a simple dummy json data array for it. Here is the json we will use for our example

First we will see how to use the pipe (filter) by using the search feature:

Create a component with name category.component.ts

    import { Component, OnInit } from '@angular/core';_x000D_
    @Component({_x000D_
      selector: 'app-category',_x000D_
      templateUrl: './category.component.html'_x000D_
    })_x000D_
    export class CategoryComponent implements OnInit {_x000D_
_x000D_
      records: Array<any>;_x000D_
      isDesc: boolean = false;_x000D_
      column: string = 'CategoryName';_x000D_
      constructor() { }_x000D_
_x000D_
      ngOnInit() {_x000D_
        this.records= [_x000D_
          { CategoryID: 1,  CategoryName: "Beverages", Description: "Coffees, teas" },_x000D_
          { CategoryID: 2,  CategoryName: "Condiments", Description: "Sweet and savory sauces" },_x000D_
          { CategoryID: 3,  CategoryName: "Confections", Description: "Desserts and candies" },_x000D_
          { CategoryID: 4,  CategoryName: "Cheeses",  Description: "Smetana, Quark and Cheddar Cheese" },_x000D_
          { CategoryID: 5,  CategoryName: "Grains/Cereals", Description: "Breads, crackers, pasta, and cereal" },_x000D_
          { CategoryID: 6,  CategoryName: "Beverages", Description: "Beers, and ales" },_x000D_
          { CategoryID: 7,  CategoryName: "Condiments", Description: "Selishes, spreads, and seasonings" },_x000D_
          { CategoryID: 8,  CategoryName: "Confections", Description: "Sweet breads" },_x000D_
          { CategoryID: 9,  CategoryName: "Cheeses",  Description: "Cheese Burger" },_x000D_
          { CategoryID: 10, CategoryName: "Grains/Cereals", Description: "Breads, crackers, pasta, and cereal" }_x000D_
         ];_x000D_
         // this.sort(this.column);_x000D_
      }_x000D_
    }

<div class="col-md-12">_x000D_
  <table class="table table-responsive table-hover">_x000D_
    <tr>_x000D_
      <th >Category ID</th>_x000D_
      <th>Category</th>_x000D_
      <th>Description</th>_x000D_
    </tr>_x000D_
    <tr *ngFor="let item of records">_x000D_
      <td>{{item.CategoryID}}</td>_x000D_
      <td>{{item.CategoryName}}</td>_x000D_
      <td>{{item.Description}}</td>_x000D_
    </tr>_x000D_
  </table>_x000D_
</div>

2.Nothing special in this code just initialize our records variable with a list of categories, two other variables isDesc and column are declared which we will use for sorting latter. At the end added this.sort(this.column); latter we will use, once we will have this method.

Note templateUrl: './category.component.html', which we will create next to show the records in tabluar format.

For this create a HTML page called category.component.html, whith following code:

3.Here we use ngFor to repeat the records and show row by row, try to run it and we can see all records in a table.

Search - Filter Records

Say we want to search the table by category name, for this let's add one text box to type and search

<div class="form-group">_x000D_
  <div class="col-md-6" >_x000D_
    <input type="text" [(ngModel)]="searchText" _x000D_
           class="form-control" placeholder="Search By Category" />_x000D_
  </div>_x000D_
</div>

5.Now we need to create a pipe to search the result by category because filter is not available as it was in angularjs any more.

Create a file category.pipe.ts and add following code in it.

    import { Pipe, PipeTransform } from '@angular/core';_x000D_
    @Pipe({ name: 'category' })_x000D_
    export class CategoryPipe implements PipeTransform {_x000D_
      transform(categories: any, searchText: any): any {_x000D_
        if(searchText == null) return categories;_x000D_
_x000D_
        return categories.filter(function(category){_x000D_
          return category.CategoryName.toLowerCase().indexOf(searchText.toLowerCase()) > -1;_x000D_
        })_x000D_
      }_x000D_
    }

6.Here in transform method we are accepting the list of categories and search text to search/filter record on the list. Import this file into our category.component.ts file, we want to use it here, as follows:

import { CategoryPipe } from './category.pipe';_x000D_
@Component({      _x000D_
  selector: 'app-category',_x000D_
  templateUrl: './category.component.html',_x000D_
  pipes: [CategoryPipe]   // This Line       _x000D_
})

7.Our ngFor loop now need to have our Pipe to filter the records so change it to this.You can see the output in image below

enter image description here

The only thing that worked for me is deleting the project and then importing it again. Works like a charm :)

Date.prototype.toUTCArray= function(){
    var D= this;
    return [D.getUTCFullYear(), D.getUTCMonth(), D.getUTCDate(), D.getUTCHours(),
    D.getUTCMinutes(), D.getUTCSeconds()];
}

Date.prototype.toISO= function(){
    var tem, A= this.toUTCArray(), i= 0;
    A[1]+= 1;
    while(i++<7){
        tem= A[i];
        if(tem<10) A[i]= '0'+tem;
    }
    return A.splice(0, 3).join('-')+'T'+A.join(':');    
}

proxy: {
        type: 'ajax',
        actionMethods: {
            read: 'POST',
            update: 'POST'
        },
        api: {
            read: '/bcm/rest/gcl/fetch',
            update: '/bcm/rest/gcl/save'
        },
        paramsAsJson: true,
        reader: {
            rootProperty: 'data',
            type: 'json'
        },
        writer: {
            allowSingle: false,
            writeAllFields: true,
            type: 'json'
        }
    }

Use allowSingle it will convert into array

The error you receive is from another method than the one you show here. It's a method that takes a parameter with the name "source". In your Visual Studio Options dialog, disable "Just my code", disable "Step over properties and operators" and enable "Enable .NET Framework source stepping". Make sure the .NET symbols can be found. Then the debugger will break inside the .NET method if it isn't your own. then check the stacktrace to find which value is passed that's null, but shouldn't.

What you should look for is a value that becomes null and prevent that. From looking at your code, it may be the itemsal.Add line that breaks.

Edit

Since you seem to have trouble with debugging in general and LINQ especially, let's try to help you out step by step (also note the expanded first section above if you still want to try it the classic way, I wasn't complete the first time around):

• Narrow down the possible error scenarios by splitting your code;
• Replace locations that can end up null with something deliberately not null;
• If all fails, rewrite your LINQ statement as loop and go through it step by step.

Step 1

First make the code a bit more readable by splitting it in manageable pieces:

// in your using-section, add this:
using Roundsman.BAL;

// keep this in your normal location
var nCounts = from sale in sal
              select new
              {
                  SaleID = sale.OrderID,
                  LineItem = GetLineItem(sale.LineItems)
              };

foreach (var item in nCounts)
{
    foreach (var itmss in item.LineItem)
    {
        itemsal.Add(CreateWeeklyStockList(itmss));
    }
}


// add this as method somewhere
WeeklyStockList CreateWeeklyStockList(LineItem lineItem)
{
    string name = itmss.Item.Name.ToString();  // isn't Name already a string?
    string code = itmss.Item.Code.ToString();  // isn't Code already a string?
    string description = itmss.Item.Description.ToString();  // isn't Description already a string?
    int quantity = Convert.ToInt32(itmss.Item.Quantity); // wouldn't (int) or "as int" be enough?

    return new WeeklyStockList(
                 name, 
                 code, 
                 description,
                 quantity, 
                 2, 2, 2, 2, 2, 2, 2, 2, 2
              );
}

// also add this as a method
LineItem GetLineItem(IEnumerable<LineItem> lineItems)
{
    // add a null-check
    if(lineItems == null)
        throw new ArgumentNullException("lineItems", "Argument cannot be null!");

    // your original code
    from sli in lineItems
    group sli by sli.Item into ItemGroup
    select new
    {
        Item = ItemGroup.Key,
        Weeks = ItemGroup.Select(s => s.Week)
    }
}

The code above is from the top of my head, of course, because I cannot know what type of classes you have and thus cannot test the code before posting. Nevertheless, if you edit it until it is correct (if it isn't so out of the box), then you already stand a large chance the actual error becomes a lot clearer. If not, you should at the very least see a different stacktrace this time (which we still eagerly await!).

Step 2

The next step is to meticulously replace each part that can result in a null reference exception. By that I mean that you replace this:

select new
{
    SaleID = sale.OrderID,
    LineItem = GetLineItem(sale.LineItems)
};

with something like this:

select new
{
    SaleID = 123,
    LineItem = GetLineItem(new LineItem(/*ctor params for empty lineitem here*/))
};

This will create rubbish output, but will narrow the problem down even further to your potential offending line. Do the same as above for other places in the LINQ statements that can end up null (just about everything).

Step 3

This step you'll have to do yourself. But if LINQ fails and gives you such headaches and such unreadable or hard-to-debug code, consider what would happen with the next problem you encounter? And what if it fails on a live environment and you have to solve it under time pressure=

The moral: it's always good to learn new techniques, but sometimes it's even better to grab back to something that's clear and understandable. Nothing against LINQ, I love it, but in this particular case, let it rest, fix it with a simple loop and revisit it in half a year or so.

Conclusion

Actually, nothing to conclude. I went a bit further then I'd normally go with the long-extended answer. I just hope it helps you tackling the problem better and gives you some tools understand how you can narrow down hard-to-debug situations, even without advanced debugging techniques (which we haven't discussed).

Here an example of how I do that, I don't know if it is the best solution, but works perfectly.

First, code in HTML. Look at ng-class, it's calling hasError function. Look also to the input's name declaration. I use the $index to create different input names.

<div data-ng-repeat="tipo in currentObject.Tipo"
    ng-class="{'has-error': hasError(planForm, 'TipoM', 'required', $index) || hasError(planForm, 'TipoM', 'maxlength', $index)}">
    <input ng-model="tipo.Nombre" maxlength="100" required
        name="{{'TipoM' + $index}}"/>

And now, here is the hasError function:

$scope.hasError = function (form, elementName, errorType, index) {
           if (form == undefined
               || elementName == undefined
               || errorType == undefined
               || index == undefined)
               return false;

           var element = form[elementName + index];
           return (element != null && element.$error[errorType] && element.$touched);
       };

To make a new list retaining the order of first elements of duplicates in L

newlist=[ii for n,ii in enumerate(L) if ii not in L[:n]]

for example if L=[1, 2, 2, 3, 4, 2, 4, 3, 5] then newlist will be [1,2,3,4,5]

This checks each new element has not appeared previously in the list before adding it. Also it does not need imports.

You can use Armory plugin which makes switching between projects comfortable. The default shortcut for Project List is Alt + A.

By default currently opened projects are displayed at the top of this list (with bold style).

As of today the download URL for the latest version of the extension is embedded verbatim in the source of the page on Marketplace, e.g. source at URL:

https://marketplace.visualstudio.com/items?itemName=lukasz-wronski.ftp-sync

contains string:

https://lukasz-wronski.gallerycdn.vsassets.io/extensions/lukasz-wronski/ftp-sync/0.3.3/1492669004156/Microsoft.VisualStudio.Services.VSIXPackage

I use following Python regexp to extract dl URL:

urlre = re.search(r'source.+(http.+Microsoft\.VisualStudio\.Services\.VSIXPackage)', content)
if urlre:
    return urlre.group(1)

It looks like XMLHttpRequest has been replaced by the Fetch API. Google published a good introduction that includes this example doing what you want:

fetch('./api/some.json')
  .then(
    function(response) {
      if (response.status !== 200) {
        console.log('Looks like there was a problem. Status Code: ' +
          response.status);
        return;
      }

      // Examine the text in the response
      response.json().then(function(data) {
        console.log(data);
      });
    }
  )
  .catch(function(err) {
    console.log('Fetch Error :-S', err);
  });

However, you probably want to call response.text() instead of response.json().

It will work in IE7. But here you need to fixed the size less than the number of option and not use overflow-y:scroll. In your example you have 2 option but you set size=10, which will not work.

Suppose your select has 10 option, then fixed size=9.

Here, in your code reference you used height:100px with size:2. I remove the height css, because its not necessary and change the size:5 and it works fine.

Here is your modified code from jsfiddle:

<select size="5" style="width:100px;">
 <option>1</option>
 <option>2</option>
 <option>3</option>
 <option>4</option>
 <option>5</option>
 <option>6</option>
</select>

this will generate a larger select box than size:2 create.In case of small size the select box will not display the scrollbar,you have to check with appropriate size quantity.Without scrollbar it will work if click on the upper and lower icons of scrollbar.I show both example in your fiddle with size:2 and size greater than 2(e.g: 3,5).

Here is your desired result. I think this will help you:

CSS

  .wrapper{
    border: 1px dashed red;
    height: 150px;
    overflow-x: hidden;
    overflow-y: scroll;
    width: 150px;
 }
 .wrapper .selection{
   width:150px;
   border:1px solid #ccc
 }

HTML

<div class="wrapper">
<select size="15" class="selection">
    <option>Item 1</option>
    <option>Item 2</option>
    <option>Item 3</option>
</select>
</div>

HTTP_CLIENT_IP is the most reliable way of getting the user's IP address. Next is HTTP_X_FORWARDED_FOR, followed by REMOTE_ADDR. Check all three, in that order, assuming that the first one that is set (isset($_SERVER['HTTP_CLIENT_IP']) returns true if that variable is set) is correct. You can independently check if the user is using a proxy using various methods. Check this out.

Building on Amine's answer, create a helper like:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString CurrencyFormat(this HtmlHelper helper, string value)
    {
        var result = string.Format("{0:C2}", value);
        return new MvcHtmlString(result);
    }
}

in your view: use @Html.CurrencyFormat(model.value)

If you are doing simple formating like Standard Numeric Formats, then simple use string.Format() in your view like in the helper example above:

@string.Format("{0:C2}", model.value)

Perhaps an example will help:

git rm --cached asd
git commit -m "the file asd is gone from the repository"

versus

git reset HEAD -- asd
git commit -m "the file asd remains in the repository"

Note that if you haven't changed anything else, the second commit won't actually do anything.

Just the same way as you would do in normal Java code.

for (Map.Entry<String, String> entry : countries.entrySet()) {
    String key = entry.getKey();
    String value = entry.getValue();
    // ...
}

However, scriptlets (raw Java code in JSP files, those <% %> things) are considered a poor practice. I recommend to install JSTL (just drop the JAR file in /WEB-INF/lib and declare the needed taglibs in top of JSP). It has a <c:forEach> tag which can iterate over among others Maps. Every iteration will give you a Map.Entry back which in turn has getKey() and getValue() methods.

Here's a basic example:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<c:forEach items="${map}" var="entry">
    Key = ${entry.key}, value = ${entry.value}<br>
</c:forEach>

Thus your particular issue can be solved as follows:

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

<select name="country">
    <c:forEach items="${countries}" var="country">
        <option value="${country.key}">${country.value}</option>
    </c:forEach>
</select>

You need a Servlet or a ServletContextListener to place the ${countries} in the desired scope. If this list is supposed to be request-based, then use the Servlet's doGet():

protected void doGet(HttpServletRequest request, HttpServletResponse response) {
    Map<String, String> countries = MainUtils.getCountries();
    request.setAttribute("countries", countries);
    request.getRequestDispatcher("/WEB-INF/page.jsp").forward(request, response);
}

Or if this list is supposed to be an application-wide constant, then use ServletContextListener's contextInitialized() so that it will be loaded only once and kept in memory:

public void contextInitialized(ServletContextEvent event) {
    Map<String, String> countries = MainUtils.getCountries();
    event.getServletContext().setAttribute("countries", countries);
}

In both cases the countries will be available in EL by ${countries}.

Hope this helps.

I liked Lost Koder's method the most. I ran into issues when trying to serialize more complex objects whos members/methods aren't serializable. Here's my implementation that works on more objects:

class Serializer(object):
    @staticmethod
    def serialize(obj):
        def check(o):
            for k, v in o.__dict__.items():
                try:
                    _ = json.dumps(v)
                    o.__dict__[k] = v
                except TypeError:
                    o.__dict__[k] = str(v)
            return o
        return json.dumps(check(obj).__dict__, indent=2)

Try this command

ps -ef | awk '/[t]omcat/{print $2}' 

It will return the pid if tomcat is running.

If anyone else comes across this, I'm adding another answer to provide the response code or other information that might be needed in the "response".

http://php.net/manual/en/function.curl-getinfo.php

// init curl object        
$ch = curl_init();

// define options
$optArray = array(
    CURLOPT_URL => 'http://www.google.com',
    CURLOPT_RETURNTRANSFER => true
);

// apply those options
curl_setopt_array($ch, $optArray);

// execute request and get response
$result = curl_exec($ch);

// also get the error and response code
$errors = curl_error($ch);
$response = curl_getinfo($ch, CURLINFO_HTTP_CODE);

curl_close($ch);

var_dump($errors);
var_dump($response);

Output:

string(0) ""
int(200)

// change www.google.com to www.googlebofus.co
string(42) "Could not resolve host: www.googlebofus.co"
int(0)

Note that git checkout --ours|--theirs will overwrite the files entirely, by choosing either theirs or ours version, which might be or might not be what you want to do (if you have any non-conflicted changes coming from the other side, they will be lost).

If instead you want to perform a three-way merge on the file, and only resolve the conflicted hunks using --ours|--theirs, while keeping non-conflicted hunks from both sides in place, you may want to resort to git merge-file; see details in this answer.

A quick workaround for this is to use numpy.core.defchararray. I also faced the same warning message and was able to resolve it using above module.

import numpy.core.defchararray as npd
resultdataset = npd.equal(dataset1, dataset2)

my solution:`

   public void onTextChanged(CharSequence s, int start, int before, int count) {
   char ch=s.charAt(start + count - 1);
   if (Character.isLetter(ch)) {
       s=s.subSequence(start, count-1);
       edittext.setText(s);
    }

Also with python3 you might find convenient to use Extended Iterable Unpacking to handle optional positional arguments without additional dependencies:

try:
   _, arg1, arg2, arg3, *_ = sys.argv + [None] * 2
except ValueError:
   print("Not enough arguments", file=sys.stderr) # unhandled exception traceback is meaningful enough also
   exit(-1)

The above argv unpack makes arg2 and arg3 "optional" - if they are not specified in argv, they will be None, while if the first is not specified, ValueError will be thouwn:

Traceback (most recent call last):
  File "test.py", line 3, in <module>
    _, arg1, arg2, arg3, *_ = sys.argv + [None] * 2
ValueError: not enough values to unpack (expected at least 4, got 3)

That's what ln is documented to do when the target already exists and is a directory. If you want /etc/nginx to be a symlink rather than contain a symlink, you had better not create it as a directory first!

I found the solution for the above program, which had the goal of signing in to http://rediff.com

public class Handle_popupNAlert
{
    public static void main(String[] args ) throws InterruptedException
    {
        WebDriver driver= new FirefoxDriver(); 
        driver.get("http://www.rediff.com/");
        WebElement sign = driver.findElement(By.xpath("//html/body/div[3]/div[3]/span[4]/span/a"));
        sign.click();

        Set<String> windowId = driver.getWindowHandles();    // get  window id of current window
        Iterator<String> itererator = windowId.iterator();   

        String mainWinID = itererator.next();
        String  newAdwinID = itererator.next();

        driver.switchTo().window(newAdwinID);
        System.out.println(driver.getTitle());
        Thread.sleep(3000);
        driver.close();

        driver.switchTo().window(mainWinID);
        System.out.println(driver.getTitle());
        Thread.sleep(2000);

        WebElement email_id= driver.findElement(By.xpath("//*[@id='c_uname']"));
        email_id.sendKeys("hi");
        Thread.sleep(5000);

        driver.close();
        driver.quit();
    }  
}

You can also do it with the keyboard shortcut shown under the simulator menu bar (Hardware-> Home).

The shortcut is ?+?+H, but you need to hit H twice in a row for it to simulate the double press that shows the apps.

There is a package that converts it for you and returns the svg as a string to implement into your reactJS file.

No, you shouldn't always. However, I tend to avoid it when there are multiple concerns on a particular object that only need to be threadsafe in respect to themselves. For example, you might have a mutable data object that has "label" and "parent" fields; these need to be threadsafe, but changing one need not block the other from being written/read. (In practice I would avoid this by declaring the fields volatile and/or using java.util.concurrent's AtomicFoo wrappers).

Synchronization in general is a bit clumsy, as it slaps a big lock down rather than thinking exactly how threads might be allowed to work around each other. Using synchronized(this) is even clumsier and anti-social, as it's saying "no-one may change anything on this class while I hold the lock". How often do you actually need to do that?

I would much rather have more granular locks; even if you do want to stop everything from changing (perhaps you're serialising the object), you can just acquire all of the locks to achieve the same thing, plus it's more explicit that way. When you use synchronized(this), it's not clear exactly why you're synchronizing, or what the side effects might be. If you use synchronized(labelMonitor), or even better labelLock.getWriteLock().lock(), it's clear what you are doing and what the effects of your critical section are limited to.

Another way is to use TRANSLATE:

TRANSLATE (col_name, 'x'||CHR(10)||CHR(13), 'x')

The 'x' is any character that you don't want translated to null, because TRANSLATE doesn't work right if the 3rd parameter is null.

val notifyIdLong = ((Date().time / 1000L) % Integer.MAX_VALUE)

notificationManager.notify(notifyIdInteger, mBuilder.build())
log.d(TAG,"notifyId = $notifyIdInteger")

For some reason my push and pull origin was changed to HTTPS-url in stead of SSH-url (probably a copy-paste error on my end), but trying to push would give me the following error after trying to login:

Username for 'https://github.com': xxx
Password for 'https://[email protected]': 
remote: Invalid username or password.

Updating the remote origin with the SSH url, solved the problem:

git remote set-url origin [email protected]:<username>/<repo>.git

Hope this helps!

You could do something like this, based on the ascii values of the characters:

char[26] alphabet;

for(int i = 0; i <26; i++)
{
     alphabet[i] = (char)(i+65); //65 is the offset for capital A in the ascaii table
}

(See the table here.) You are just casting from the int value of the character to the character value - but, that only works for ascii characters not different languages etc.

EDIT: As suggested by Mehrdad in the comment to a similar solution, it's better to do this:

alphabet[i] = (char)(i+(int)('A'));

This casts the A character to it's int value and then increments based on this, so it's not hardcoded.

It looks like you're running this on Windows (given your H://log.txt file path).

Try using \r\n instead of just \n.

Honestly, \n is fine; you're probably viewing the log file in notepad or something else that doesn't render non-Windows newlines. Try opening it in a different viewer/editor (e.g. Wordpad).

when using the categorical_crossentropy loss, your targets should be in categorical format (e.g. if you have 10 classes, the target for each sample should be a 10-dimensional vector that is all-zeros except for a 1 at the index corresponding to the class of the sample).

Pero's answer got me here :)

I wanted to rename files relative to time as the image viewers did not display images in time order.

bash # run that command

If I understand correctly, you want PowerShell to send the ENTER keystroke to some interactive application?

$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('title of the application window')
Sleep 1
$wshell.SendKeys('~')

If that interactive application is a PowerShell script, just use whatever is in the title bar of the PowerShell window as the argument to AppActivate (by default, the path to powershell.exe). To avoid ambiguity, you can have your script retitle its own window by using the title 'new window title' command.

A few notes:

• The tilde (~) represents the ENTER keystroke. You can also use {ENTER}, though they're not identical - that's the keypad's ENTER key. A complete list is available here: http://msdn.microsoft.com/en-us/library/office/aa202943%28v=office.10%29.aspx.
• The reason for the Sleep 1 statement is to wait 1 second because it takes a moment for the window to activate, and if you invoke SendKeys immediately, it'll send the keys to the PowerShell window, or to nowhere.
• Be aware that this can be tripped up, if you type anything or click the mouse during the second that it's waiting, preventing to window you activate with AppActivate from being active. You can experiment with reducing the amount of time to find the minimum that's reliably sufficient on your system (Sleep accepts decimals, so you could try .5 for half a second). I find that on my 2.6 GHz Core i7 Win7 laptop, anything less than .8 seconds has a significant failure rate. I use 1 second to be safe.
• IMPORTANT WARNING: Be extra careful if you're using this method to send a password, because activating a different window between invoking AppActivate and invoking SendKeys will cause the password to be sent to that different window in plain text!

Sometimes wscript.shell's SendKeys method can be a little quirky, so if you run into problems, replace the fourth line above with this:

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.SendKeys]::SendWait('~');

First difference - Fail Fast

I agree with @zzzzBov's answer, but the "fail fast" advantage of Promise.all is not the only difference. Some users in the comments have asked why using Promise.all is worth it when it's only faster in the negative scenario (when some task fails). And I ask, why not? If I have two independent async parallel tasks and the first one takes a very long time to resolve but the second is rejected in a very short time, why leave the user to wait for the longer call to finish to receive an error message? In real-life applications we must consider the negative scenario. But OK - in this first difference you can decide which alternative to use: Promise.all vs. multiple await.

Second difference - Error Handling

But when considering error handling, YOU MUST use Promise.all. It is not possible to correctly handle errors of async parallel tasks triggered with multiple awaits. In the negative scenario you will always end with UnhandledPromiseRejectionWarning and PromiseRejectionHandledWarning, regardless of where you use try/ catch. That is why Promise.all was designed. Of course someone could say that we can suppress those errors using process.on('unhandledRejection', err => {}) and process.on('rejectionHandled', err => {}) but this is not good practice. I've found many examples on the internet that do not consider error handling for two or more independent async parallel tasks at all, or consider it but in the wrong way - just using try/ catch and hoping it will catch errors. It's almost impossible to find good practice in this.

Summary

TL;DR: Never use multiple await for two or more independent async parallel tasks, because you will not be able to handle errors correctly. Always use Promise.all() for this use case.

Async/ await is not a replacement for Promises, it's just a pretty way to use promises. Async code is written in "sync style" and we can avoid multiple thens in promises.

Some people say that when using Promise.all() we can't handle task errors separately, and that we can only handle the error from the first rejected promise (separate handling can be useful e.g. for logging). This is not a problem - see "Addition" heading at the bottom of this answer.

Examples

Consider this async task...

const task = function(taskNum, seconds, negativeScenario) {
  return new Promise((resolve, reject) => {
    setTimeout(_ => {
      if (negativeScenario)
        reject(new Error('Task ' + taskNum + ' failed!'));
      else
        resolve('Task ' + taskNum + ' succeed!');
    }, seconds * 1000)
  });
};

When you run tasks in the positive scenario there is no difference between Promise.all and multiple awaits. Both examples end with Task 1 succeed! Task 2 succeed! after 5 seconds.

// Promise.all alternative
const run = async function() {
  // tasks run immediate in parallel and wait for both results
  let [r1, r2] = await Promise.all([
    task(1, 5, false),
    task(2, 5, false)
  ]);
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: Task 1 succeed! Task 2 succeed!

// multiple await alternative
const run = async function() {
  // tasks run immediate in parallel
  let t1 = task(1, 5, false);
  let t2 = task(2, 5, false);
  // wait for both results
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: Task 1 succeed! Task 2 succeed!

However, when the first task takes 10 seconds and succeeds, and the second task takes 5 seconds but fails, there are differences in the errors issued.

// Promise.all alternative
const run = async function() {
  let [r1, r2] = await Promise.all([
      task(1, 10, false),
      task(2, 5, true)
  ]);
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!

// multiple await alternative
const run = async function() {
  let t1 = task(1, 10, false);
  let t2 = task(2, 5, true);
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};
run();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)
// at 10th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!

We should already notice here that we are doing something wrong when using multiple awaits in parallel. Let's try handling the errors:

// Promise.all alternative
const run = async function() {
  let [r1, r2] = await Promise.all([
    task(1, 10, false),
    task(2, 5, true)
  ]);
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Caught error', err); });
// at 5th sec: Caught error Error: Task 2 failed!

As you can see, to successfully handle errors, we need to add just one catch to the run function and add code with catch logic into the callback. We do not need to handle errors inside the run function because async functions do this automatically - promise rejection of the task function causes rejection of the run function.

To avoid a callback we can use "sync style" (async/ await + try/ catch)
try { await run(); } catch(err) { }
but in this example it's not possible, because we can't use await in the main thread - it can only be used in async functions (because nobody wants to block main thread). To test if handling works in "sync style" we can call the run function from another async function or use an IIFE (Immediately Invoked Function Expression: MDN):

(async function() { 
  try { 
    await run(); 
  } catch(err) { 
    console.log('Caught error', err); 
  }
})();

This is the only correct way to run two or more async parallel tasks and handle errors. You should avoid the examples below.

Bad Examples

// multiple await alternative
const run = async function() {
  let t1 = task(1, 10, false);
  let t2 = task(2, 5, true);
  let r1 = await t1;
  let r2 = await t2;
  console.log(r1 + ' ' + r2);
};

We can try to handle errors in the code above in several ways...

try { run(); } catch(err) { console.log('Caught error', err); };
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled 

... nothing got caught because it handles sync code but run is async.

run().catch(err => { console.log('Caught error', err); });
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: Caught error Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... huh? We see firstly that the error for task 2 was not handled and later that it was caught. Misleading and still full of errors in console, it's still unusable this way.

(async function() { try { await run(); } catch(err) { console.log('Caught error', err); }; })();
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: Caught error Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... the same as above. User @Qwerty in his deleted answer asked about this strange behavior where an error seems to be caught but are also unhandled. We catch error the because run() is rejected on the line with the await keyword and can be caught using try/ catch when calling run(). We also get an unhandled error because we are calling an async task function synchronously (without the await keyword), and this task runs and fails outside the run() function.
It is similar to when we are not able to handle errors by try/ catch when calling some sync function which calls setTimeout:

function test() {
  setTimeout(function() { 
    console.log(causesError); 
    }, 0);
}; 
try { 
  test(); 
} catch(e) { 
  /* this will never catch error */ 
}`.

Another poor example:

const run = async function() {
  try {
    let t1 = task(1, 10, false);
    let t2 = task(2, 5, true);
    let r1 = await t1;
    let r2 = await t2;
  }
  catch (err) {
    return new Error(err);
  }
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Caught error', err); });
// at 5th sec: UnhandledPromiseRejectionWarning: Error: Task 2 failed!
// at 10th sec: PromiseRejectionHandledWarning: Promise rejection was handled asynchronously (rejection id: 1)

... "only" two errors (3rd one is missing) but nothing is caught.

Addition (handling separate task errors and also first-fail error)

const run = async function() {
  let [r1, r2] = await Promise.all([
    task(1, 10, true).catch(err => { console.log('Task 1 failed!'); throw err; }),
    task(2, 5, true).catch(err => { console.log('Task 2 failed!'); throw err; })
  ]);
  console.log(r1 + ' ' + r2);
};
run().catch(err => { console.log('Run failed (does not matter which task)!'); });
// at 5th sec: Task 2 failed!
// at 5th sec: Run failed (does not matter which task)!
// at 10th sec: Task 1 failed!

... note that in this example I rejected both tasks to better demonstrate what happens (throw err is used to fire final error).

You can convert to an array and call array soring methods on it:

[...map].sort(/* etc */);

git reset HEAD <file> 

for removing a particular file from the index.

and

git reset HEAD

for removing all indexed files.

Try this regular expression:

\w*Id\b

\w* allows word characters in front of Id and the \b ensures that Id is at the end of the word (\b is word boundary assertion).

A slight variation of user2966600's solution...

To redirect all except a single URL (In case of multiple frontend/backend):

redirect scheme https if !{ hdr(Host) -i www.mydomain.com } !{ ssl_fc }

You can do this as follows:

std::sort(v.begin(), v.end());
v.erase(std::unique(v.begin(), v.end()), v.end());

I think you are looking for Integer.parseInt. The second argument takes a radix, which in this case is 2.

Integer.parseInt(c, 2)

What worked for me

import databricks.koalas as ks

df1k = df1.to_koalas()
df2k = df2.to_koalas()
df3k = df1k.merge(df2k, on=['col1', 'col2'])
df3 = df3k.to_spark()

All of the columns except for col1 and col2 had "_x" appended to their names if they had come from df1 and "_y" appended if they had come from df2, which is exactly what I needed.

Here is an old version I have that works on version 1.0 of the .NET framework and does not need generic types.

public static Array RemoveAt(Array source, int index)
{
    if (source == null)
        throw new ArgumentNullException("source");

    if (0 > index || index >= source.Length)
        throw new ArgumentOutOfRangeException("index", index, "index is outside the bounds of source array");

    Array dest = Array.CreateInstance(source.GetType().GetElementType(), source.Length - 1);
    Array.Copy(source, 0, dest, 0, index);
    Array.Copy(source, index + 1, dest, index, source.Length - index - 1);

    return dest;
}

This is used like this:

class Program
{
    static void Main(string[] args)
    {
        string[] x = new string[20];
        for (int i = 0; i < x.Length; i++)
            x[i] = (i+1).ToString();

        string[] y = (string[])MyArrayFunctions.RemoveAt(x, 3);

        for (int i = 0; i < y.Length; i++)
            Console.WriteLine(y[i]);
    }
}

Inside in yours classses on which is complain maven is some dependecy which belongs to some jar's try right these jars re-build with maven command, i use this command mvn clean install -DskipTests=true should be work in this case when some symbols from classes is missing

This is what you need!

function onGeneratedRow(columnsResult)
{
    var jsonData = {};
    columnsResult.forEach(function(column) 
    {
        var columnName = column.metadata.colName;
        jsonData[columnName] = column.value;
    });
    viewData.employees.push(jsonData);
 }

It's an array, so you're looking for Count to test for contents.

I'd recommend

$foo.count -gt 0

The "why" of this is related to how PSH handles comparison of collection objects

Also you may omit the AS keyword.
SELECT row1 Price, row2 'Other Price' FROM exampleDB.table1;
in this option readability is a bit degraded but you have desired result.

I don't know how Kosher it is, but I found that this scheme moves the ViewController's view down and provides the status bar with a solid background:

- (void)viewDidLoad {
    [super viewDidLoad];

    // Shove everything down if iOS 7 or later
    float systemVersion = [[[UIDevice currentDevice] systemVersion] floatValue];
    if (systemVersion >= 7.0f) {

        // Move the view down 20 pixels
        CGRect bounds = self.view.bounds;
        bounds.origin.y -= 20.0;
        [self.view setBounds:bounds];

        // Create a solid color background for the status bar
        CGRect statusFrame = CGRectMake(0.0, -20.0, bounds.size.width, 20);
        UIView* statusBar = [[UIView alloc] initWithFrame:statusFrame];
        statusBar.backgroundColor = [UIColor redColor];
        [self.view addSubview:statusBar];
    }

Of course, replace redColor with whatever color you want for the background.

You must separately do one of the swizzles to set the color of the characters/symbols in the status bar. I use View controller-based status bar appearance = NO and Status bar style = Opaque black style in the plist, to do this globally.

Seems to work, and I'd be interested to hear of any bugs or issues with it.

  Intent callIntent = new Intent(Intent.ACTION_CALL);  
  callIntent.setData(Uri.parse("tel:"+number));  
   startActivity(callIntent);   

 **Add permission :**

 <uses-permission android:name="android.permission.CALL_PHONE" />          

Try this one for current selection:

Sub A_SelectAllMakeTable2()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, Selection, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

or equivalent of your macro (for Ctrl+Shift+End range selection):

Sub A_SelectAllMakeTable()
    Dim tbl As ListObject
    Dim rng As Range

    Set rng = Range(Range("A1"), Range("A1").SpecialCells(xlLastCell))
    Set tbl = ActiveSheet.ListObjects.Add(xlSrcRange, rng, , xlYes)
    tbl.TableStyle = "TableStyleMedium15"
End Sub

To center it, you can use the technique shown here: Absolute centering.

To make it as big as possible, give it max-width and max-height of 100%.

To maintain the aspect ratio (even when the width is specifically set like in the snippet below), use object-fit as explained here.

.className {
    max-width: 100%;
    max-height: 100%;
    bottom: 0;
    left: 0;
    margin: auto;
    overflow: auto;
    position: fixed;
    right: 0;
    top: 0;
    -o-object-fit: contain;
    object-fit: contain;
}

MySQL casts to Decimal:

Cast bare integer to decimal:

select cast(9 as decimal(4,2));       //prints 9.00

Cast Integers 8/5 to decimal:

select cast(8/5 as decimal(11,4));    //prints 1.6000

Cast string to decimal:

select cast(".885" as decimal(11,3));   //prints 0.885

Cast two int variables into a decimal

mysql> select 5 into @myvar1;
Query OK, 1 row affected (0.00 sec)

mysql> select 8 into @myvar2;
Query OK, 1 row affected (0.00 sec)

mysql> select @myvar1/@myvar2;   //prints 0.6250

Cast decimal back to string:

select cast(1.552 as char(10));   //shows "1.552"

A very pythonic and practical way to do it is by using the string join() method:

str.join(iterable)

The official Python documentations says:

Return a string which is the concatenation of the strings in iterable... The separator between elements is the string providing this method.

How to use it?

Remember: this is a string method.

This method will be applied to the str above, which reflects the string that will be used as separator of the items in the iterable.

Let's have some practical example!

iterable = "BINGO"
separator = " " # A whitespace character.
                # The string to which the method will be applied
separator.join(iterable)
> 'B I N G O'

In practice you would do it like this:

iterable = "BINGO"    
" ".join(iterable)
> 'B I N G O'

But remember that the argument is an iterable, like a string, list, tuple. Although the method returns a string.

iterable = ['B', 'I', 'N', 'G', 'O']    
" ".join(iterable)
> 'B I N G O'

What happens if you use a hyphen as a string instead?

iterable = ['B', 'I', 'N', 'G', 'O']    
"-".join(iterable)
> 'B-I-N-G-O'

In more recent browsers code like below may be enough.

<object data="https://www.w3.org/TR/PNG/iso_8859-1.txt" width="300" height="200">_x000D_

</object>

If you use the Oracle native data provider rather than the Microsoft driver then you can get at all field types

Dim cn As New Oracle.DataAccess.Client.OracleConnection
Dim cm As New Oracle.DataAccess.Client.OracleCommand
Dim dr As Oracle.DataAccess.Client.OracleDataReader

The connection string does not require a Provider value so you would use something like:

"Data Source=myOracle;UserID=Me;Password=secret"

Open the connection:

cn.ConnectionString = "Data Source=myOracle;UserID=Me;Password=secret"
cn.Open()

Attach the command and set the Sql statement

cm.Connection = cn
cm.CommandText = strCommand

Set the Fetch size. I use 4000 because it's as big as a varchar can be

cm.InitialLONGFetchSize = 4000

Start the reader and loop through the records/columns

dr = cm.ExecuteReader

Do while dr.read()
    strMyLongString = dr(i)
Loop

You can be more specific with the read, eg dr.GetOracleString(i) dr.GetOracleClob(i) etc. if you first identify the data type in the column. If you're reading a LONG datatype then the simple dr(i) or dr.GetOracleString(i) works fine. The key is to ensure that the InitialLONGFetchSize is big enough for the datatype. Note also that the native driver does not support CommandBehavior.SequentialAccess for the data reader but you don't need it and also, the LONG field does not even have to be the last field in the select statement.

Presuming you get the timestamp in Helsinki time, I would create a date object set to midnight January 1 1970 UTC (for disregarding the local timezone settings of the browser). Then just add the needed number of milliseconds to it.

var _date = new Date( Date.UTC(1970, 0, 1, 0, 0, 0, 0) );_x000D_
_date.setUTCMilliseconds(1270544790922);_x000D_
_x000D_
alert(_date); //date shown shifted corresponding to local time settings_x000D_
alert(_date.getUTCFullYear());    //the UTC year value_x000D_
alert(_date.getUTCMonth());       //the UTC month value_x000D_
alert(_date.getUTCDate());        //the UTC day of month value_x000D_
alert(_date.getUTCHours());       //the UTC hour value_x000D_
alert(_date.getUTCMinutes());     //the UTC minutes value

Watch out later, to always ask UTC values from the date object. This way users will see the same date values regardless of local settings. Otherwise date values will be shifted corresponding to local time settings.

With template literals, you can use multiple spaces or multi-line strings and string interpolation. Template Literals are a new ES2015 / ES6 feature that allows you to work with strings. The syntax is very simple, just use backticks instead of single or double quotes:

let a = `something                 something`;

and to make multiline strings just press enter to create a new line, with no special characters:

let a = `something 

    
                         something`;

The results are exactly the same as you write in the string.

Multiple commands' output can be redirected. This works for either the command line or most usefully in a bash script. The -s directs the password prompt to the screen.

Hereblock cmds stdout/stderr are sent to seperate files and nothing to display.

sudo -s -u username <<'EOF' 2>err 1>out
ls; pwd;
EOF

Hereblock cmds stdout/stderr are sent to a single file and display.

sudo -s -u username <<'EOF' 2>&1 | tee out
ls; pwd;
EOF

Hereblock cmds stdout/stderr are sent to separate files and stdout to display.

sudo -s -u username <<'EOF' 2>err | tee out
ls; pwd;
EOF

Depending on who you are(whoami) and username a password may or may not be required.

I know it's been a long time, but still the most obvious solution via fold (aka reduce in js) is missing, for the sake of completeness i'll leave it here:

function mapO(f, o) {
  return Object.keys(o).reduce((acc, key) => {
    acc[key] = f(o[key])
    return acc
  }, {})
}

Unfortunately max-width + max-height do not fully cover my task... So I have found another solution:

To save the Image ratio while scaling you also can use object-fit CSS3 propperty.

Useful article: Control image aspect ratios with CSS3

img {
    width: 100%; /* or any custom size */
    height: 100%; 
    object-fit: contain;
}

Bad news: IE not supported (Can I Use)

to convert the current datetime to file name to save files you can use

DateTime.Now.ToFileTime();

this should resolve your objective

Why so complicated? just put this :

data-html='true'

Here I have a solution that avoid multiple requests, for loops and old document removal.

You can easily create a new idea manually using something like:_id:ObjectId() But knowing Mongo will automatically assign an _id if missing, you can use aggregate to create a $project containing all the fields of your document, but omit the field _id. You can then save it with $out

So if your document is:

{
"_id":ObjectId("5b5ed345cfbce6787588e480"),
"title": "foo",
"description": "bar"
}

Then your query will be:

    db.getCollection('myCollection').aggregate([
        {$match:
             {_id: ObjectId("5b5ed345cfbce6787588e480")}
        }        
        {$project:
            {
             title: '$title',
             description: '$description'             
            }     
        },
        {$out: 'myCollection'}
    ])

find path -type f | xargs -L1 command 

is all you need.

In Linux Mint 18 Cinnamon be sure to check /etc/profile.d/jdk_home.sh I renamed this file to jdk_home.sh.old and now my path does not keep getting overridden and I can call java -version and see Java 9 as expected. Even though I correctly selected Java 9 in update-aternatives --config java this jdk_home.sh file kept overriding the $PATH on boot-up.

Python 3.7 is now available to be installed, but many packages have not been updated yet. As noted by another answer here, there is a GitHub issue tracking the progress of Anaconda building all the updated packages.

Until someone creates a conda package for Python 3.7, you can't install it. Unfortunately, something like 3500 packages show up in a search for "python" on Anaconda.org (https://anaconda.org/search?q=%22python%22) so I couldn't see if anyone has done that yet.

You might be able to build your own package, depending on what OS you want it for. You can start with the recipe that conda-forge uses to build Python: https://github.com/conda-forge/python-feedstock/

In the past, I think Continuum have generally waited until a stable release to push out packages for new Pythons, but I don't work there, so I don't know what their actual policy is.

Yes there is no change event for currently selected radio button. But problem is when each radio button is taken as a separate element. Instead a radio group should be considered a single element like select. So change event is triggered for that group. If it is a select element we never worry about each option in it, but take only the selected option. We store the current value in a variable which will become the previous value, when a new option is selected. Similarly you have to use a separate variable for storing value of checked radio button.

If you want to identify the previous radio button, you have to loop on mousedown event.

var radios = document.getElementsByName("myRadios");
var val;
for(var i = 0; i < radios.length; i++){
    if(radios[i].checked){
        val = radios[i].value;
    }
}

Set it in the body selector of your css. E.g.

In mathematics, there are sets and ordered sets (osets).

• set: an unordered container of unique elements (Implemented)
• oset: an ordered container of unique elements (NotImplemented)

In Python, only sets are directly implemented. We can emulate osets with regular dict keys (3.7+).

Given

a = [1, 2, 20, 6, 210, 2, 1]
b = {2, 6}

Code

oset = dict.fromkeys(a).keys()
# dict_keys([1, 2, 20, 6, 210])

Demo

Replicates are removed, insertion-order is preserved.

list(oset)
# [1, 2, 20, 6, 210]

Set-like operations on dict keys.

oset - b
# {1, 20, 210}

oset | b
# {1, 2, 5, 6, 20, 210}

oset & b
# {2, 6}

oset ^ b
# {1, 5, 20, 210}

Details

Note: an unordered structure does not preclude ordered elements. Rather, maintained order is not guaranteed. Example:

assert {1, 2, 3} == {2, 3, 1}                    # sets (order is ignored)

assert [1, 2, 3] != [2, 3, 1]                    # lists (order is guaranteed)

One may be pleased to discover that a list and multiset (mset) are two more fascinating, mathematical data structures:

• list: an ordered container of elements that permits replicates (Implemented)
• mset: an unordered container of elements that permits replicates (NotImplemented)*

Summary

Container | Ordered | Unique | Implemented
----------|---------|--------|------------
set       |    n    |    y   |     y
oset      |    y    |    y   |     n
list      |    y    |    n   |     y
mset      |    n    |    n   |     n*  

^{*A multiset can be indirectly emulated with collections.Counter(), a dict-like mapping of multiplicities (counts).}

If you have a parent container with vertical padding and you want something (e.g. an image) inside that container to ignore its vertical padding you can set a negative, but equal, margin for both 'top' and 'bottom':

margin-top: -100px;
margin-bottom: -100px;

The actual value doesn't appear to matter much. Haven't tried this for horizontal paddings.

The think that following would probably work in python 3:

def get_flat_iter(xparent):
    try:
        r = xparent
        if hasattr(xx, '__iter__'):
            iparent = iter(xparent)
            if iparent != xparent:
                r = map(a, xparent)
    finally:
         pass
    return r

irregular_list = [1, [2, [3, 4]]]
flat_list = list(irregular_list)
print(flat_list) # [1, 2, 3, 4]

                        case 'Y': return LANIDX_CY;
                      }
                      break;
          case 'D':   switch(Lan[1]) {
                        case 'A': return LANIDX_DA;

LANIDX_* being constant integers used to index in arrays.

You can vertically align a div in another div. See this example on JSFiddle or consider the example below.

HTML

<div class="outerDiv">
    <div class="innerDiv"> My Vertical Div </div>
</div>

CSS

.outerDiv {
    display: inline-flex;  // <-- This is responsible for vertical alignment
    height: 400px;
    background-color: red;
    color: white;
}

.innerDiv {
    margin: auto 5px;   // <-- This is responsible for vertical alignment
    background-color: green;   
}

The .innerDiv's margin must be in this format: margin: auto *px;

[Where, * is your desired value.]

display: inline-flex is supported in the latest (updated/current version) browsers with HTML5 support.

It may not work in Internet Explorer :P :)

Always try to define a height for any vertically aligned div (i.e. innerDiv) to counter compatibility issues.

I don't know if this will help, but here's the SWT FAQ question How do I use Mozilla as the Browser's underlying renderer?

Edit: Having researched this further, it sounds like this isn't possible in Eclipse 3.4, but may be slated for a later release.

There is a third-party log4net adapter for the ASP.NET Core logging interface.

Only thing you need to do is pass the ILoggerFactory to your Startup class, then call

loggerFactory.AddLog4Net();

and have a config in place. So you don't have to write any boiler-plate code.

I have same problem. It just the javascript's script loads too fast--before the HTML's element loaded. So the browser returning null, since the browser can't find where is the element you like to manipulate.

Another js alternative:

Working Example

fontsize = function () {
    var fontSize = $("#container").width() * 0.10; // 10% of container width
    $("#container h1").css('font-size', fontSize);
};
$(window).resize(fontsize);
$(document).ready(fontsize);

Or as stated in torazaburo's answer you could use svg. I put together a simple example as a proof of concept:

SVG Example

<div id="container">
    <svg width="100%" height="100%" viewBox="0 0 13 15">
        <text x="0" y="13">X</text>
    </svg>
</div>

It's not built into the SDK, but you can use the Zxing library. It's free, open source, and Apache-licensed.

The 2016 recommendation is to use the Barcode API, which also works offline.

My answer is according to the documentation, which works fine.

1) In xml file include android:onClick="onRadioButtonClicked" as shown below:

<RadioGroup
android:id="@+id/rg1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
<RadioButton
    android:id="@+id/b1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="onCreateOptionsMenu()"
    android:onClick="onRadioButtonClicked"
            />
<RadioButton
    android:id="@+id/b2"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="onCreateMenu()"
    android:onClick="onRadioButtonClicked"
            />
</RadioGroup>

2) In Java file implement onRadioButtonClicked method outside onCreate() method as shown below:

public void onRadioButtonClicked(View view) {
    // Is the button now checked?
    boolean checked = ((RadioButton) view).isChecked();

    // Check which radio button was clicked
    switch(view.getId()) {
        case R.id.b1:
            if (checked)
            {
                Log.e("b1", "b1" );
                break;
            }
        case R.id.b2:
            if (checked)
                break;
    }
}

I answered a similar question here.

In the Project’s Settings, add /FORCE:MULTIPLE to the Linker’s Command Line options.

From MSDN: "Use /FORCE:MULTIPLE to create an output file whether or not LINK finds more than one definition for a symbol."

That's what programmers call a "quick and dirty" solution, but sometimes you just want the build to be completed and get to the bottom of the problem later, so that's kind of a ad-hoc solution. To actually avoid this error, provided that you want

int WIDTH = 1024;
int HEIGHT = 800;

to be shared among several source files, just declare them only in a single .c / .cpp file, and refer to them in a header file:

extern int WIDTH;
extern int HEIGHT;

Then include the header in any other source file you wish these global variables to be available.

The send pattern is a one-to-one relationship. If you want to "send" to more than one receiver you should be using the pub/sub pattern. See http://www.rabbitmq.com/tutorials/tutorial-three-python.html for more details.

As others have pointed out, the $x are capture variables for regular expressions, allowing you to reference sections of a matched pattern.

Perl also supports named captures which might be easier for humans to remember in some cases.

Given input: 111 222

/(\d+)\s+(\d+)/

$1 is 111

$2 is 222

One could also say:

/(?<myvara>\d+)\s+(?<myvarb>\d+)/

$+{myvara} is 111

$+{myvarb} is 222

Your best bet is to use find with tar, via xargs (to handle the large number of arguments). For example:

find / -print0 | xargs -0 tar cjf tarfile.tar.bz2

Here's a solution that doesn't use negative margins or calc. Run the snippet below to see the final result.

Explanation

We give the header and the footer a fixed height of 30px and position them absolutely at the top and bottom, respectively. To prevent the content from falling underneath, we use two classes: below-header and above-footer to pad the div above and below with 30px.

All of the content is wrapped in a position: relative div so that the header and footer are at the top/bottom of the content and not the window.

We use the classes fit-to-parent and min-fit-to-parent to make the content fill out the page. This gives us a sticky footer which is at least as low as the window, but hidden if the content is longer than the window.

Inside the header and footer, we use the display: table and display: table-cell styles to give the header and footer some vertical padding without disrupting the shrink-wrap quality of the page. (Giving them real padding can cause the total height of the page to be more than 100%, which causes a scroll bar to appear when it isn't really needed.)

This is a solution where you have many fields in your table and don't want to get a finger cramp from typing all the fields, just type the ones needed :)

How to copy some rows into the same table, with some fields having different values:

1. Create a temporary table with all the rows you want to copy
2. Update all the rows in the temporary table with the values you want
3. If you have an auto increment field, you should set it to NULL in the temporary table
4. Copy all the rows of the temporary table into your original table
5. Delete the temporary table

Your code:

CREATE table temporary_table AS SELECT * FROM original_table WHERE Event_ID="155";

UPDATE temporary_table SET Event_ID="120";

UPDATE temporary_table SET ID=NULL

INSERT INTO original_table SELECT * FROM temporary_table;

DROP TABLE temporary_table

General scenario code:

CREATE table temporary_table AS SELECT * FROM original_table WHERE <conditions>;

UPDATE temporary_table SET <fieldx>=<valuex>, <fieldy>=<valuey>, ...;

UPDATE temporary_table SET <auto_inc_field>=NULL;

INSERT INTO original_table SELECT * FROM temporary_table;

DROP TABLE temporary_table

Simplified/condensed code:

CREATE TEMPORARY TABLE temporary_table AS SELECT * FROM original_table WHERE <conditions>;

UPDATE temporary_table SET <auto_inc_field>=NULL, <fieldx>=<valuex>, <fieldy>=<valuey>, ...;

INSERT INTO original_table SELECT * FROM temporary_table;

As creation of the temporary table uses the TEMPORARY keyword it will be dropped automatically when the session finishes (as @ar34z suggested).

Following JavaScript function handles ', ", \b, \t, \n, \f or \r equivalent of php function addslashes().

function addslashes(string) {
    return string.replace(/\\/g, '\\\\').
        replace(/\u0008/g, '\\b').
        replace(/\t/g, '\\t').
        replace(/\n/g, '\\n').
        replace(/\f/g, '\\f').
        replace(/\r/g, '\\r').
        replace(/'/g, '\\\'').
        replace(/"/g, '\\"');
}

Use multiselect function as below.

$('#drp_Books_Ill_Illustrations').multiSelect('select', 'value');

Also echo json_encode($dataobject); might be helpful

getResourceAsStream is the right way to do it for web apps (as you already learned).

The reason is that reading from the file system cannot work if you package your web app in a WAR. This is the proper way to package a web app. It's portable that way, because you aren't dependent on an absolute file path or the location where your app server is installed.

I use this simple playbook:

---
# vars.yml
#
# Shows the value of all variables/facts.
#
# Example:
#
#   ansible-playbook vars.yml -e 'hosts=localhost'
#
- hosts: localhost
  tasks:
    - fail: "You must specify a value for `hosts` variable - e.g.: ansible-playbook vars.yml -e 'hosts=localhost'"
      when: hosts is not defined

- hosts: "{{ hosts }}"
  tasks:
    - debug: var=vars
    - debug: var=hostvars[inventory_hostname]

In this particular case the clearest solution is the S.Lott answer

But in some complex logical conditions I would prefer use some boolean algebra to get a clear solution.

Using De Morgan's law ¬(A^B) = ¬Av¬B

not (u0 <= u and u < u0+step)
(not u0 <= u) or (not u < u0+step)
u0 > u or u >= u0+step

then

if u0 > u or u >= u0+step:
    pass

... in this case the «clear» solution is not more clear :P

Starting from Java 9, there is a new utility method allowing to create an immutable entry which is Map#entry(Object, Object).

Here is a simple example:

Entry<String, String> entry = Map.entry("foo", "bar");

As it is immutable, calling setValue will throw an UnsupportedOperationException. The other limitations are the fact that it is not serializable and null as key or value is forbidden, if it is not acceptable for you, you will need to use AbstractMap.SimpleImmutableEntry or AbstractMap.SimpleEntry instead.

NB: If your need is to create directly a Map with 0 to up to 10 (key, value) pairs, you can instead use the methods of type Map.of(K key1, V value1, ...).

According to Flexbugs:

In IE 10-11, min-height declarations on flex containers work to size the containers themselves, but their flex item children do not seem to know the size of their parents. They act as if no height has been set at all.

Here are a couple of workarounds:

1. Always fill the viewport + scrollable <aside> and <section>:

html {
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
  height: 100%;
  margin: 0;
}

header,
footer {
  background: #7092bf;
}

main {
  flex: 1;
  display: flex;
}

aside, section {
  overflow: auto;
}

aside {
  flex: 0 0 150px;
  background: #3e48cc;
}

section {
  flex: 1;
  background: #9ad9ea;
}

<header>
  <p>header</p>
</header>

<main>
  <aside>
    <p>aside</p>
  </aside>
  <section>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
  </section>
</main>

<footer>
  <p>footer</p>
</footer>

2. Fill the viewport initially + normal page scroll with more content:

html {
  height: 100%;
}

body {
  display: flex;
  flex-direction: column;
  height: 100%;
  margin: 0;
}

header,
footer {
  background: #7092bf;
}

main {
  flex: 1 0 auto;
  display: flex;
}

aside {
  flex: 0 0 150px;
  background: #3e48cc;
}

section {
  flex: 1;
  background: #9ad9ea;
}

<header>
  <p>header</p>
</header>

<main>
  <aside>
    <p>aside</p>
  </aside>
  <section>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
    <p>content</p>
  </section>
</main>

<footer>
  <p>footer</p>
</footer>

Just like you do for getting something from the CNode you also need to do for the ANode

XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
  XmlNode anode = xn.SelectSingleNode("ANode");
    if (anode!= null)
    {
        string id = anode["ID"].InnerText;
        string date = anode["Date"].InnerText;
        XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
        foreach (XmlNode node in CNodes)
        {
         XmlNode example = node.SelectSingleNode("Example");
         if (example != null)
         {
            string na = example["Name"].InnerText;
            string no = example["NO"].InnerText;
         }
        }
    }
}

Just add to the CommandArgument parameter and read it out on the Click handler:

<asp:LinkButton ID="ENameLinkBtn" runat="server" 
    style="font-weight: 700; font-size: 8pt;" CommandArgument="YourValueHere" 
    OnClick="ENameLinkBtn_Click" >

Then in your click event:

protected void ENameLinkBtn_Click(object sender, EventArgs e)
{
    LinkButton btn = (LinkButton)(sender);
    string yourValue = btn.CommandArgument;
    // do what you need here
}   

Also you can set the CommandArgument argument when binding if you are using the LinkButton in any bindable controls by doing:

CommandArgument='<%# Eval("SomeFieldYouNeedArguementFrom") %>'

There are a few misunderstandings in the discussion above.

First, you can always ROLLBACK a transaction... no matter what the state of the transaction. So you only have to check the XACT_STATE before a COMMIT, not before a rollback.

As far as the error in the code, you will want to put the transaction inside the TRY. Then in your CATCH, the first thing you should do is the following:

 IF @@TRANCOUNT > 0
      ROLLBACK TRANSACTION @transaction

Then, after the statement above, then you can send an email or whatever is needed. (FYI: If you send the email BEFORE the rollback, then you will definitely get the "cannot... write to log file" error.)

This issue was from last year, so I hope you have resolved this by now :-) Remus pointed you in the right direction.

As a rule of thumb... the TRY will immediately jump to the CATCH when there is an error. Then, when you're in the CATCH, you can use the XACT_STATE to decide whether you can commit. But if you always want to ROLLBACK in the catch, then you don't need to check the state at all.

For update() and saveOrUpdate() methods, id generator value should be there in the database. For the save() method, id generator is not required.

How about:

Dir["/path/to/directory/*.rb"].each {|file| require file }

This works for me:

function isTouchDevice(){
    return true == ("ontouchstart" in window || window.DocumentTouch && document instanceof DocumentTouch);
}

I have solved this problem on my side by 2 ways:

1. Adding this configuration in pom.xml

   <configuration><argLine>-Xmx1024m</argLine></configuration>
   

2. Switch to used JDK 1.7 instead of 1.6

Bind-address XXX.XX.XX.XXX in /etc/my.cnf

comment line:

skip-networking

or

skip-external-locking

after edit hit service mysqld restart

login into mysql and hit this query:

GRANT ALL PRIVILEGES ON dbname.* TO 'username'@'%' IDENTIFIED BY 'password';

FLUSH PRIVILEGES;
quit;

add firewall rule:

iptables -I INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPT

static __attribute__ ((noinline))  void foo()
{

}

This is what worked for me.

Add a column to your existing data to get rid of the hour:minute:second time stamp on each row:

 =DATE(YEAR(A1), MONTH(A1), DAY(A1))

Extend this down the length of your data. Even easier: quit collecting the hh:mm:ss data if you don't need it. Assuming your date/time was in column A, and your value was in column B, you'd put the above formula in column C, and auto-extend it for all your data.

Now, in another column (let's say E), create a series of dates corresponding to each day of the specific month you're interested in. Just type the first date, (for example, 10/7/2016 in E1), and auto-extend. Then, in the cell next to the first date, F1, enter:

=SUMIF(C:C, E1, B:B )

autoextend the formula to cover every date in the month, and you're done. Begin at 1/1/2016, and auto-extend for the whole year if you like.

I found that I had to discover the inside of the extension method I was trying to mock the input for, and mock what was going on inside the extension.

I viewed using an extension as adding code directly to your method. This meant I needed to mock what happens inside the extension rather than the extension itself.

In general keeping data like this is not a great thing to do if you can avoid it, because people are always confusing tabs and spaces.

Solving your problem is very straightforward in a scripting language like Perl, Python or Ruby. Here's some example code:

#!/usr/bin/perl -w

use strict;

my $sort_field = 2;
my $split_regex = qr{\s+};

my @data;
push @data, "7 8\t 9";
push @data, "4 5\t 6";
push @data, "1 2\t 3";

my @sorted_data = 
    map  { $_->[1] }
    sort { $a->[0] <=> $b->[0] }
    map  { [ ( split $split_regex, $_ )[$sort_field], $_ ] }
    @data;

print "unsorted\n";
print join "\n", @data, "\n";
print "sorted by $sort_field, lines split by $split_regex\n";
print join "\n", @sorted_data, "\n";

You can host an internal NuGet Server and share the common libraries that will be shared in other projects internally and externally.

Further on this read

Try

//book[title/@lang = 'it']

This reads:

• get all book elements
  • that have at least one title
    • which has an attribute lang
      • with a value of "it"

You may find this helpful — it's an article entitled "XPath in Five Paragraphs" by Ronald Bourret.

But in all honesty, //book[title[@lang='it']] and the above should be equivalent, unless your XPath engine has "issues." So it could be something in the code or sample XML that you're not showing us -- for example, your sample is an XML fragment. Could it be that the root element has a namespace, and you aren't counting for that in your query? And you only told us that it didn't work, but you didn't tell us what results you did get.

Get rid of the values keyword and the parens. You can see an example here.

This is basic INSERT syntax:

INSERT INTO "table_name" ("column1", "column2", ...)
VALUES ("value1", "value2", ...);

This is the INSERT SELECT syntax:

INSERT INTO "table1" ("column1", "column2", ...)
SELECT "column3", "column4", ...
FROM "table2";

Spring Data JPA 1.11 now supports the exists projection in repository query derivation.

See documentation here.

In your case the following will work:

public interface MyEntityRepository extends CrudRepository<MyEntity, String> {  
    boolean existsByFoo(String foo);
}

This works like a charm:

1. Remove the "disabled" attributes
2. Submit the form
3. Add the attributes again. The best way to do this is to use a setTimeOut function, e.g. with a 1 millisecond delay.

The only disadvantage is the short flashing up of the disabled input fields when submitting. At least in my scenario that isn´t much of a problem!

$('form').bind('submit', function () {
  var $inputs = $(this).find(':input'),
      disabledInputs = [],
      $curInput;

  // remove attributes
  for (var i = 0; i < $inputs.length; i++) {
    $curInput = $($inputs[i]);

    if ($curInput.attr('disabled') !== undefined) {
      $curInput.removeAttr('disabled');
      disabledInputs.push(true);
    } else 
      disabledInputs.push(false);
  }

  // add attributes
  setTimeout(function() {
    for (var i = 0; i < $inputs.length; i++) {

      if (disabledInputs[i] === true)
        $($inputs[i]).attr('disabled', true);

    }
  }, 1);

});

If you recently reached here as I did when searching for the same error in vain you may find it to be an update to NSS causing failure on CentOS. Test by running yum update and see if you get errors, curl also creates this error. Solution is simple enough just install NSS manually.

Read on...

If you're like me it threw up an error similar to this:

curl: (77) Problem with the SSL CA cert (path? access rights?)

This took some time to solve but found that it wasn't the CA cert because by recreating them and checking all the configuration I had ruled it out. It could have been libcurl so I went in search of updates.

As mentioned I recreated CA certs. You can do this also but it may be a waste of time. http://wiki.centos.org/HowTos/Https

The next step (probably should of been my first) was to check that everything was up-to-date by simply running yum.

$ yum update
$ yum upgrade

This gave me an affirmative answer that there was a bigger problem at play: Downloading Packages: error: rpmts_HdrFromFdno: Header V3 RSA/SHA1 Signature, key ID c105b9de: BAD Problem opening package nss-softokn-freebl-3.14.3–19.el6_6.x86_64.rpm I started reading about Certificate Verification with NSS and how this new update may be related to my problems. So yum is broken. This is because nss-softokn-* needs nss-softokn-freebl-* need each other to function. The problem is they don't check each others version for compatibility and in some cases it ends up breaking yum. Lets go fix things:

$ wget http://mirrors.linode.com/centos/6.6/updates/x86_64/Packages/nsssoftokn-freebl-3.14.3-19.el6_6.x86_64.rpm
$ rpm -Uvh nss-softokn-freebl-3.14.3–19.el6_6.x86_64.rpm
$ yum update

You should of course download from your nearest mirror and check for the correct version / OS etc. We basically download and install the update from the rpm to fix yum. As @grumpysysadmin pointed out you can shorten the commands down. @cwgtex contributed that you should install the upgrade using the RPM command making the process even simplier.

To fix things with wordpress you need to restart your http server.

$ service httpd restart

Try again and success!

for others that find this in the search:

I often get this one when I accidentally call a function using the class name rather than the object name. This typically happens because i give them too similar names : P

ie:

MyClass myclass = new MyClass();

// then later

MyClass.someFunction();

This is obviously a static method. (good for somethings) But what i really wanted to do (in most cases was)

myclass.someFunction();

It's such a silly mistake, but every couple of months, i waste about 30 mins messing with vars in the "MyClass" definitions to work out what im doing wrong when really, its just a typo.

Funny note: stack overflow highlights the syntax to make the mistake really obvious here.

From crtdbg.h (and many other headers):

#ifndef NULL
#ifdef __cplusplus
#define NULL    0
#else
#define NULL    ((void *)0)
#endif
#endif

Therefore NULL is 0, at least on the Windows platform. So no, not that I know of.

I'm faced with the same problem and came across this post. Is this what's meant by the IDictionary approach:

Dictionary<Type, int> typeDict = new Dictionary<Type, int>
{
    {typeof(int),0},
    {typeof(string),1},
    {typeof(MyClass),2}
};

void Foo(object o)
{
    switch (typeDict[o.GetType()])
    {
        case 0:
            Print("I'm a number.");
            break;
        case 1:
            Print("I'm a text.");
            break;
        case 2:
            Print("I'm classy.");
            break;
        default:
            break;
    }
}

If so, I can't say I'm a fan of reconciling the numbers in the dictionary with the case statements.

This would be ideal but the dictionary reference kills it:

void FantasyFoo(object o)
{
    switch (typeDict[o.GetType()])
    {
        case typeDict[typeof(int)]:
            Print("I'm a number.");
            break;
        case typeDict[typeof(string)]:
            Print("I'm a text.");
            break;
        case typeDict[typeof(MyClass)]:
            Print("I'm classy.");
            break;
        default:
            break;
    }
}

Is there another implementation I've overlooked?

If you are using sakila-db from mysql website, It's very easy on the Linux platform just follow the below-mentioned steps, After downloading the zip file of sakila-db, extract it. Now you will have two files, one is sakila-schema.sql and the other one is sakila-data.sql.

1. Open terminal
2. Enter command mysql -u root -p < sakila-schema.sql
3. Enter command mysql -u root -p < sakila-data.sql
4. Now enter command mysql -u root -p and enter your password, now you have entered into mysql system with default database.
5. To use sakila database, use this command use sakila;
6. To see tables in sakila-db, use show tables command

Please take care that extracted files are present in home directory.

Don't worry...! Follow these below steps and you will get your signed .apk file. I was also worry about that, but these step get ride me off from the frustration. Steps to sign your application:

1. Export the unsigned package:

Right click on the project in Eclipse -> Android Tools -> Export Unsigned Application Package (like here we export our GoogleDriveApp.apk to Desktop)

Sign the application using your keystore and the jarsigner tool (follow below steps):

Open cmd-->change directory where your "jarsigner.exe" exist (like here in my system it exist at "C:\Program Files\Java\jdk1.6.0_17\bin"

Now enter belwo command in cmd:

jarsigner -verbose -keystore c:\users\android\debug.keystore c:\users\pir fahim\Desktops\GoogleDriveApp.apk my_keystore_alias

It will ask you to provide your password: Enter Passphrase for keystore: It will sign your apk.To verify that the signing is successful you can run:

jarsigner -verify c:\users\pir fahim\Desktops\GoogleDriveApp.apk

It should come back with: jar verified.

Method 2

If you are using eclipse with ADT, then it is simple to compiled, signed, aligned, and ready the file for distribution.what you have to do just follow this steps.

• File > Export.
• Export android application
• Browse-->select your project
• Next-->Next

These steps will compiled, signed and zip aligned your project and now you are ready to distribute your project or upload at Google Play store.

By far the nicest and simplest DateTime picker option is http://trentrichardson.com/examples/timepicker/.

It is an extension of the jQuery UI Datepicker so it will support the same themes as well it works very much the same way, similar syntax, etc. This should be packaged with the jQuery UI imo.

Short answer: You can't.

Technically there is an accurate way, which would be checking the property:

history.previous

However, it won't work. The problem with this is that in most browsers this is considered a security violation and usually just returns undefined.

history.length

Is a property that others have suggested...
However, the length doesn't work completely because it doesn't indicate where in the history you are. Additionally, it doesn't always start at the same number. A browser not set to have a landing page, for example, starts at 0 while another browser that uses a landing page will start at 1.

Most of the time a link is added that calls:

history.back();

or

 history.go(-1);

and it's just expected that if you can't go back then clicking the link does nothing.

if object_id('FUNCTION_NAME') is not NULL
   DROP FUNCTION <name>

You can also look the name up in sysobjects

IF EXISTS (SELECT * 
       FROM   sysobjects 
           WHERE name='<function name>' and xtype='FN'

Actually, if the function could be a table function, you need to use

xtype in ('FN','TF')

This worked for me!

String amount= "123.0000";
String.Format("{0:0.##}", amount);      // "123.00"

Converting to str is definitely slower then dividing by 10.

map is sligthly slower than list comprehension:

convert to string with map 2.13599181175
convert to string with list comprehension 1.92812991142
modulo, division, recursive 0.948769807816
modulo, division 0.699964046478

These times were returned by the following code on my laptop:

foo = """\
def foo(limit):
    return sorted(set(map(sum, map(lambda x: map(int, list(str(x))), map(lambda x: x * 9, range(limit))))))

foo(%i)
"""

bar = """\
def bar(limit):
    return sorted(set([sum([int(i) for i in str(n)]) for n in [k *9 for k in range(limit)]]))

bar(%i)
"""

rac = """\
def digits(n):
    return [n] if n<10 else digits(n / 10)+[n %% 10]

def rabbit(limit):

rabbit(%i)
"""

rab = """\

    return sorted(set([sum_digits(n) for n in [k *9 for k in range(limit)]]))

import timeit

print "convert to string with map", timeit.timeit(foo % 100, number=10000)

One thing to recognize when using the ternary operator that it is an expression not a statement.

In functional languages like scheme the distinction doesn't exists:

(if (> a b) a b)

Conditional ?: Operator "Doesn't seem to be as flexible as the if/else construct"

In functional languages it is.

When programming in imperative languages I apply the ternary operator in situations where I typically would use expressions (assignment, conditional statements, etc).

Sorry to post answer for very old thread. my answer may help other in future.

string[] TobeDistinct = {"Name","City","State"};
DataTable dtDistinct = GetDistinctRecords(DTwithDuplicate, TobeDistinct);

    //Following function will return Distinct records for Name, City and State column.
    public static DataTable GetDistinctRecords(DataTable dt, string[] Columns)
       {
           DataTable dtUniqRecords = new DataTable();
           dtUniqRecords = dt.DefaultView.ToTable(true, Columns);
           return dtUniqRecords;
       }

You can use arguments with default values.

def someMethod(def mandatory,def optional=null){}

if argument "optional" not exist, it turns to "null".

An additional cause of this issue, is if you have Instant Run enabled for Android Studio.

The fix

If you find you start getting this error, turn off Instant Run.

1. Android Studio main settings
2. Build, Execution, Deployment
3. Instant Run
4. Untick "Enable instant run..."

Why

Instant Run modifies a large number of things during development, to make it quicker to provide updates to your running App. Hence instant run. When it works, it is really useful. However, when an issue such as this strikes, the best thing to do is to turn off Instant Run until the next version of Android Studio releases.

This works for me (Excel 2013):

Public Sub StartExeWithArgument()
    Dim strProgramName As String
    Dim strArgument As String

    strProgramName = "C:\Program Files\Test\foobar.exe"
    strArgument = "/G"

    Call Shell("""" & strProgramName & """ """ & strArgument & """", vbNormalFocus)
End Sub

The version archive is sorted newest at the top, but Anaconda2 ABOVE Anaconda3.

I needed to convert a specific PDF to plain text within a python module. I used PDFMiner 20110515, after reading through their pdf2txt.py tool I wrote this simple snippet:

from cStringIO import StringIO
from pdfminer.pdfinterp import PDFResourceManager, process_pdf
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams

def to_txt(pdf_path):
    input_ = file(pdf_path, 'rb')
    output = StringIO()

    manager = PDFResourceManager()
    converter = TextConverter(manager, output, laparams=LAParams())
    process_pdf(manager, converter, input_)

    return output.getvalue() 

You can be more precise with CSS background-origin:

background-origin: content-box;

This will make image respect the padding of the box.

clone() was designed with several mistakes (see this question), so it's best to avoid it.

From Effective Java 2nd Edition, Item 11: Override clone judiciously

Given all of the problems associated with Cloneable, it’s safe to say that other interfaces should not extend it, and that classes designed for inheritance (Item 17) should not implement it. Because of its many shortcomings, some expert programmers simply choose never to override the clone method and never to invoke it except, perhaps, to copy arrays. If you design a class for inheritance, be aware that if you choose not to provide a well-behaved protected clone method, it will be impossible for subclasses to implement Cloneable.

This book also describes the many advantages copy constructors have over Cloneable/clone.

• They don't rely on a risk-prone extralinguistic object creation mechanism
• They don't demand unenforceable adherence to thinly documented conventions
