Very, very late to answer this one, but I've just discovered that using a background-image that is encoded as a base64 URI in the CSS, rather than held as a separate image, continues to animate in IE8.

I have the following in a types.ts file for html input, select, and textarea:

export type InputChangeEventHandler = React.ChangeEventHandler<HTMLInputElement>
export type TextareaChangeEventHandler = React.ChangeEventHandler<HTMLTextAreaElement>
export type SelectChangeEventHandler = React.ChangeEventHandler<HTMLSelectElement>

Then import them:

import { InputChangeEventHandler } from '../types'

Then use them:

const updateName: InputChangeEventHandler = (event) => {
  // Do something with `event.currentTarget.value`
}
const updateBio: TextareaChangeEventHandler = (event) => {
  // Do something with `event.currentTarget.value`
}
const updateSize: SelectChangeEventHandler = (event) => {
  // Do something with `event.currentTarget.value`
}

Then apply the functions on your markup (replacing ... with other necessary props):

<input onChange={updateName} ... />
<textarea onChange={updateName} ... />
<select onChange={updateSize} ... >
  // ...
</select>

Use Keystore Explorer gui - http://keystore-explorer.sourceforge.net/ - allows you to extract the private key from a .jks in various formats.

Without preg_replace()

$str = "This is   a Text \n and so on \t     Text text.";
$str = str_replace(["\r", "\n", "\t"], " ", $str);
while (strpos($str, "  ") !== false)
{
    $str = str_replace("  ", " ", $str);
}
echo $str;

Not sure if this is what you're after, but it will loop through the range that you gave it and if it finds an "A" it will remove it from the cell. I'm not sure what oldStr is used for...

Private Sub foo()
Dim myString As String
RowCount = WorksheetFunction.CountA(Range("A:A"))

For i = 2 To RowCount
    myString = Trim(Cells(i, 1).Value)
    If InStr(myString, "A") > 0 Then
        Cells(i, 1).Value = Left(myString, InStr(myString, "A"))
    End If
Next
End Sub

Add image in repository from upload file option then in README file

![Alt text]("enter image url of repositoryhere") 

I cleared this use. By using this site click Here , follow the steps, the same steps follows upto the ubuntu version 18.04

StringUtils.isBlank() checks that each character of the string is a whitespace character (or that the string is empty or that it's null). This is totally different than just checking if the string is empty.

From the linked documentation:

Checks if a String is whitespace, empty ("") or null.

 StringUtils.isBlank(null)      = true
 StringUtils.isBlank("")        = true  
 StringUtils.isBlank(" ")       = true  
 StringUtils.isBlank("bob")     = false  
 StringUtils.isBlank("  bob  ") = false

For comparison StringUtils.isEmpty:

 StringUtils.isEmpty(null)      = true
 StringUtils.isEmpty("")        = true  
 StringUtils.isEmpty(" ")       = false  
 StringUtils.isEmpty("bob")     = false  
 StringUtils.isEmpty("  bob  ") = false

Warning: In java.lang.String.isBlank() and java.lang.String.isEmpty() work the same except they don't return true for null.

java.lang.String.isBlank() (since Java 11)

java.lang.String.isEmpty()

I like Zarembisty's answer. Although, if you want to be more explicit, you can always do:

if len(my_list) == 0:
    print "my_list is empty"

Based on your description of what you want to do, the code seems to be correct as it is. ENDIF isn't a valid SQL loop control keyword. Are you sure that the INSERTS are actually pulling data to put into @Classes? In fact, if it was bad it just wouldn't run.

What you might want to try is to put a few PRINT statements in there. Put a PRINT above each of the INSERTS just outputting some silly text to show that that line is executing. If you get both outputs, then your SELECT...INSERT... is suspect. You could also just do the SELECT in place of the PRINT (that is, without the INSERT) and see exactly what data is being pulled.

If you want to drop rows of data frame on the basis of some complicated condition on the column value then writing that in the way shown above can be complicated. I have the following simpler solution which always works. Let us assume that you want to drop the column with 'header' so get that column in a list first.

text_data = df['name'].tolist()

now apply some function on the every element of the list and put that in a panda series:

text_length = pd.Series([func(t) for t in text_data])

in my case I was just trying to get the number of tokens:

text_length = pd.Series([len(t.split()) for t in text_data])

now add one extra column with the above series in the data frame:

df = df.assign(text_length = text_length .values)

now we can apply condition on the new column such as:

df = df[df.text_length  >  10]

def pass_filter(df, label, length, pass_type):

    text_data = df[label].tolist()

    text_length = pd.Series([len(t.split()) for t in text_data])

    df = df.assign(text_length = text_length .values)

    if pass_type == 'high':
        df = df[df.text_length  >  length]

    if pass_type == 'low':
        df = df[df.text_length  <  length]

    df = df.drop(columns=['text_length'])

    return df

You can use swift.quicktype.io for converting JSON to either struct or class. Even you can mention version of swift to genrate code.

Example JSON:

{
  "message": "Hello, World!"
}

Generated code:

import Foundation

typealias Sample = OtherSample

struct OtherSample: Codable {
    let message: String
}

// Serialization extensions

extension OtherSample {
    static func from(json: String, using encoding: String.Encoding = .utf8) -> OtherSample? {
        guard let data = json.data(using: encoding) else { return nil }
        return OtherSample.from(data: data)
    }

    static func from(data: Data) -> OtherSample? {
        let decoder = JSONDecoder()
        return try? decoder.decode(OtherSample.self, from: data)
    }

    var jsonData: Data? {
        let encoder = JSONEncoder()
        return try? encoder.encode(self)
    }

    var jsonString: String? {
        guard let data = self.jsonData else { return nil }
        return String(data: data, encoding: .utf8)
    }
}

extension OtherSample {
    enum CodingKeys: String, CodingKey {
        case message
    }
}

You can try and add a new run configuration: Run -> Run Configurations ... -> Select "Java Appliction" and click "New".

Alternatively use the shortcut: place the cursor in the class, then press Alt + Shift + X to open up a context menu, then press J.

You can use customValidity

$(function(){     var elements = document.getElementsByTagName("input");     for (var i = 0; i < elements.length; i++) {         elements[i].oninvalid = function(e) {             e.target.setCustomValidity("This can't be left blank!");         };     } }); 

I think that will work on at least Chrome and FF, I'm not sure about other browsers

As long as you don't need to support versions of Internet Explorer earlier than IE8, you can use display: table-cell to accomplish this:

HTML:

<div class="outer">
    <div class="inner">
        <p>Menu or Whatever</p>
    </div>
    <div class="inner">
        <p>Page contents...</p>
    </div>
</div>

CSS:

.inner {
    display: table-cell;
}

This will force each element with the .inner class to occupy the full height of its parent element.

Following up on Timores's elegant solution, I have found that the following creates a vertical fill in a vertical LinearLayout and a horizontal fill in a horizontal LinearLayout:

<Space
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1" />

You're sending JSON-formatted data to a server which isn't expecting that format. You already provided the format that the server needs, so you'll need to format it yourself which is pretty simple.

var data = '"title='+title+'" "text='+text+'" "file='+file+'"';
$http.post(uploadUrl, data)

When using sonar-scanner for swift, use sonar.coverage.exclusions in your sonar-project.properties to exclude any file for only code coverage. If you want to exclude files from analysis as well, you can use sonar.exclusions. This has worked for me in swift

sonar.coverage.exclusions=**/*ViewController.swift,**/*Cell.swift,**/*View.swift

I'm using this way:

IIF(EXISTS (SELECT TOP 1 1 
                FROM Users 
                WHERE FirstName = 'John'), 1, 0) AS DoesJohnExist

TL;DR: If it works, avoid, or use specifiers like __attribute__, otherwise _Pragma.

This is a short version of my blog article Suppressing Warnings in GCC and Clang.

Consider the following Makefile

CPPFLAGS:=-std=c11 -W -Wall -pedantic -Werror

.PHONY: all
all: puts

for building the following puts.c source code

#include <stdio.h>

int main(int argc, const char *argv[])
{
    while (*++argv) puts(*argv);
    return 0;
}

It will not compile because argc is unused, and the settings are hardcore (-W -Wall -pedantic -Werror).

There are 5 things you could do:

• Improve the source code, if possible
• Use a declaration specifier, like __attribute__
• Use _Pragma
• Use #pragma
• Use a command line option.

Improving the source

The first attempt should be checking if the source code can be improved to get rid of the warning. In this case we don't want to change the algorithm just because of that, as argc is redundant with !*argv (NULL after last element).

Using a declaration specifier, like __attribute__

#include <stdio.h>

int main(__attribute__((unused)) int argc, const char *argv[])
{
    while (*++argv) puts(*argv);
    return 0;
}

If you're lucky, the standard provides a specifier for your situation, like _Noreturn.

__attribute__ is proprietary GCC extension (supported by Clang and some other compilers like armcc as well) and will not be understood by many other compilers. Put __attribute__((unused)) inside a macro if you want portable code.

_Pragma operator

_Pragma can be used as an alternative to #pragma.

#include <stdio.h>

_Pragma("GCC diagnostic push")
_Pragma("GCC diagnostic ignored \"-Wunused-parameter\"")

int main(int argc, const char *argv[])
{
    while (*++argv) puts(*argv);
    return 0;
}
_Pragma("GCC diagnostic pop")

The main advantage of the _Pragma operator is that you could put it inside macros, which is not possible with the #pragma directive.

Downside: It's almost a tactical nuke, as it works line-based instead of declaration-based.

The _Pragma operator was introduced in C99.

#pragma directive.

We could change the source code to suppress the warning for a region of code, typically an entire function:

#include <stdio.h>

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused-parameter"
int main(int argc, const char *argv[])
{
    while (*++argc) puts(*argv);
    return 0;
}
#pragma GCC diagnostic pop

Downside: It's almost a tactical nuke, as it works line-based instead of declaration-based.

Note that a similar syntax exists in clang.

Suppressing the warning on the command line for a single file

We could add the following line to the Makefile to suppress the warning specifically for puts:

CPPFLAGS:=-std=c11 -W -Wall -pedantic -Werror

.PHONY: all
all: puts

puts.o: CPPFLAGS+=-Wno-unused-parameter

This is probably not want you want in your particular case, but it may help other reads who are in similar situations.

You could use

awk '/test_pattern/ {
    match($0, /test_pattern/); print substr($0, RSTART - 10, RLENGTH + 20);
}' file

I do this without external libaries:

var yourArray = ['aaa','bbb','ccc'];
var counter = [];

yourArray.forEach(function(name){
    conn.collection(name).drop(function(err) {
        counter.push(true);
        console.log('dropped');
        if(counter.length === yourArray.length){
            console.log('all dropped');
        }
    });                
});

My issue is :

return __import__('MySQLdb')
ImportError: No module named MySQLdb

and my resolution :

pip install MySQL-python
yum install mysql-devel.x86_64

at the very beginning, i just installed MySQL-python, but the issue still existed. So i think if this issue happened, you should also take mysql-devel into consideration. Hope this helps.

There is Effort which is an in memory entity framework database provider. I've not actually tried it... Haa just spotted this was mentioned in the question!

Alternatively you could switch to EntityFrameworkCore which has an in memory database provider built-in.

The simplest way to check the existence of the column in mongo compass is :

{ 'column_name': { $exists: true } }

Use document.location.reload(true) it will not load page from cache.

We can implement the basic authorization without needing any module

//1.
var http = require('http');

//2.
var credentials = {
    userName: "vikas kohli",
    password: "vikas123"
};
var realm = 'Basic Authentication';

//3.
function authenticationStatus(resp) {
    resp.writeHead(401, { 'WWW-Authenticate': 'Basic realm="' + realm + '"' });
    resp.end('Authorization is needed');

};

//4.
var server = http.createServer(function (request, response) {
    var authentication, loginInfo;

    //5.
    if (!request.headers.authorization) {
        authenticationStatus (response);
        return;
    }

    //6.
    authentication = request.headers.authorization.replace(/^Basic/, '');

    //7.
    authentication = (new Buffer(authentication, 'base64')).toString('utf8');

    //8.
    loginInfo = authentication.split(':');

    //9.
    if (loginInfo[0] === credentials.userName && loginInfo[1] === credentials.password) {
        response.end('Great You are Authenticated...');
         // now you call url by commenting the above line and pass the next() function
    }else{

    authenticationStatus (response);

}

});
 server.listen(5050);

The error is exactly what it says it is; you're trying to take sumall[0] when sumall is an int and that doesn't make any sense. What do you believe sumall should be?

// "Main" is name of .storybord file "
let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
// "MiniGameView" is the ID given to the ViewController in the interfacebuilder
// MiniGameViewController is the CLASS name of the ViewController.swift file acosiated to the ViewController
var setViewController = mainStoryboard.instantiateViewControllerWithIdentifier("MiniGameView") as MiniGameViewController
var rootViewController = self.window!.rootViewController
rootViewController?.presentViewController(setViewController, animated: false, completion: nil)

This worked fine for me when i put it in AppDelegate

Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS

// Example using HTTP POST operation

var page = require('webpage').create(),
    server = 'http://posttestserver.com/post.php?dump',
    data = 'universe=expanding&answer=42';

page.open(server, 'post', data, function (status) {
    if (status !== 'success') {
        console.log('Unable to post!');
    } else {
        console.log(page.content);
    }
    phantom.exit();
});

... or MyEnum.values() ? Or am I missing something?

In my case where I had the problem I was referring to a module when I tried extending the class.

import logging
class UserdefinedLogging(logging):

If you look at the Documentation Info, you'll see "logging" displayed as module.

In this specific case I had to simply inherit the logging module to create an extra class for the logging.

While I strongly disagree with the idea of running a laravel app on shared hosting (a bad idea all around), this package would likely solve your problem. It is a package that allows you to run some artisan commands from the web. It's far from perfect, but can work for some usecases.

https://github.com/recca0120/laravel-terminal

Two of the most widely used parsers are Expat and libxml.

If you are okay with using C++, there's Xerces-C++ too.

There is probably no need to use the ldpi , mdpi or hdpi qualifiers in this case.

When you define a dimension in a resource file you include the measurement unit. If you use sp units they are scaled according to the screen density so text at 15sp should appear roughly the same size on screens of differing density.
(The real screen density of the device isn't going to exactly match as Android generalises screen density into 120, 160, 240, 320, 480 and 640 dpi groups.)

When calling getResources().getDimension(R.dimen.textsize) it will return the size in pixels. If using sp it will scaled by the screen density,

Calling setText(float) sets the size in sp units. This is where the issue is,
i.e you have pixels measurements on one hand and sp unit on the other to fix do this:

textView.setTextSize(TypedValue.COMPLEX_UNIT_PX,
    getResources().getDimension(R.dimen.textsize));

Note you can also use

getResources().getDimensionPixelSize(R.dimen.textSize);

instead of getDimension() and it will round and convert to an non fractional value.

On a linux server you can just use this commands to reconfigure Tomcat to listen on port 80:

sed -i 's|port="8080"|port="80"|g' /etc/tomcat?/server.xml
sed -i 's|#AUTHBIND=no|AUTHBIND=yes|g' /etc/default/tomcat?
service tomcat8 restart

The div take the height of its parent, but since it has no content (expecpt for your divs) it will only be as height as its content.

You need to set the height of the body and html:

HTML:

<div class="block12">
    <div class="block1">1</div>
    <div class="block2">2</div>
</div>
<div class="block3">3</div>

CSS:

body, html {
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
}
.block12 {
    width: 100%;
    height: 50%;
    background: yellow;
    overflow: auto;
}
.block1, .block2 {
    width: 50%;
    height: 100%;
    display: inline-block;
    margin-right: -4px;
    background: lightgreen;
}
.block2 { background: lightgray }
.block3 {
    width: 100%;
    height: 50%;
    background: lightblue;
}

This question already has many answers, but in some cases you can settle for something simpler than all of them. If the string you're looking for is known (hardcoded), you can use regular expressions without any quoting etc.

Check if a string starts with 'ABC':

preg_match('/^ABC/', $myString); // "^" here means beginning of string

ends with 'ABC':

preg_match('/ABC$/', $myString); // "$" here means end of string

In my simple case, I wanted to check if a string ends with slash:

preg_match('#/$#', $myPath);   // Use "#" as delimiter instead of escaping slash

The advantage: since it's very short and simple, you don't have to define a function (such as endsWith()) as shown above.

But again -- this is not a solution for every case, just this very specific one.

You should be able to use the variable name directly

ansible_ssh_host

Or you can go through hostvars without having to specify the host literally by using the magic variable inventory_hostname

hostvars[inventory_hostname].ansible_ssh_host

Note before you read the rest: The shell script shown here is certainly not safe to use and well tested. Use at your own risk!

I wrote a bash script to accomplish that task. Suppose your library is lib1 and the one you need to include some symbols from is lib2. The script now runs in a loop, where it first checks which undefined symbols from lib1 can be found in lib2. It then extracts the corresponding object files from lib2 with ar, renames them a bit, and puts them into lib1. Now there may be more missing symbols, because the stuff you included from lib2 needs other stuff from lib2, which we haven't included yet, so the loop needs to run again. If after some passes of the loop there are no changes anymore, i.e. no object files from lib2 added to lib1, the loop can stop.

Note, that the included symbols are still reported as undefined by nm, so I'm keeping track of the object files, that were added to lib1, themselves, in order to determine whether the loop can be stopped.

#! /bin/bash

lib1="$1"
lib2="$2"

if [ ! -e $lib1.backup ]; then
    echo backing up
    cp $lib1 $lib1.backup
fi

remove_later=""

new_tmp_file() {
    file=$(mktemp)
    remove_later="$remove_later $file"
    eval $1=$file
}
remove_tmp_files() {
    rm $remove_later
}
trap remove_tmp_files EXIT

find_symbols() {
    nm $1 $2 | cut -c20- | sort | uniq 
}

new_tmp_file lib2symbols
new_tmp_file currsymbols

nm $lib2 -s --defined-only > $lib2symbols

prefix="xyz_import_"
pass=0
while true; do
    ((pass++))
    echo "Starting pass #$pass"
    curr=$lib1
    find_symbols $curr "--undefined-only" > $currsymbols
    changed=0
    for sym in $(cat $currsymbols); do
        for obj in $(egrep "^$sym in .*\.o" $lib2symbols | cut -d" " -f3); do
            echo "  Found $sym in $obj."
            if [ -e "$prefix$obj" ]; then continue; fi
            echo "    -> Adding $obj to $lib1"
            ar x $lib2 $obj
            mv $obj "$prefix$obj"
            ar -r -s $lib1 "$prefix$obj"
            remove_later="$remove_later $prefix$obj"
            ((changed=changed+1))
        done
    done
    echo "Found $changed changes in pass #$pass"

    if [[ $changed == 0 ]]; then break; fi
done

I named that script libcomp, so you can call it then e.g. with

./libcomp libmylib.a libwhatever.a

where libwhatever is where you want to include symbols from. However, I think it's safest to copy everything into a separate directory first. I wouldn't trust my script so much (however, it worked for me; I could include libgsl.a into my numerics library with that and leave out that -lgsl compiler switch).

A callback URL will be invoked by the API method you're calling after it's done. So if you call

POST /api.example.com/foo?callbackURL=http://my.server.com/bar

Then when /foo is finished, it sends a request to http://my.server.com/bar. The contents and method of that request are going to vary - check the documentation for the API you're accessing.

The accepted answer (its image) is wrong, at least now in QT5. Instead you should assign a layout to the root object/widget (pointing to the aforementioned image, it should be the MainWindow instead of centralWidget). Also note that you must have at least one QObject created beneath it for this to work. Do this and your ui will become responsive to window resizing.

This is a stab in the dark, but maybe do you need to wrap your JSON arguments; like say something like this:

data: "{'Ids':[{'Id1':'2'},{'Id2':'2'}]}"

Make sure your JSON is properly formed?

Java 9 offers a Matcher.replaceAll() that accepts a replacement function:

resultString = regexMatcher.replaceAll(
        m -> String.valueOf(Integer.parseInt(m.group()) * 3));

I have a solution. in my JS I have two functions. First to get Cookies (ie. csrftoken):

function getCookie(name) {
let cookieValue = null;
if (document.cookie && document.cookie !== '') {
    const cookies = document.cookie.split(';');
    for (let i = 0; i < cookies.length; i++) {
        const cookie = cookies[i].trim();
        // Does this cookie string begin with the name we want?
        if (cookie.substring(0, name.length + 1) === (name + '=')) {
            cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
            break;
        }
    }
}
return cookieValue;

}

Second one is my ajax function. in this case it's for login and in fact doesn't return any thing, just pass values to set a session:

function LoginAjax() {


    //get scrftoken:
    const csrftoken = getCookie('csrftoken');

    var req = new XMLHttpRequest();
    var userName = document.getElementById("Login-Username");
    var password = document.getElementById("Login-Password");

    req.onreadystatechange = function () {
        if (this.readyState == 4 && this.status == 200) {            
            //read response loggedIn JSON show me if user logged in or not
            var respond = JSON.parse(this.responseText);            
            alert(respond.loggedIn);

        }
    }

    req.open("POST", "login", true);

    //following header set scrftoken to resolve problem
    req.setRequestHeader('X-CSRFToken', csrftoken);

    req.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
    req.send("UserName=" + userName.value + "&Password=" + password.value);
}

I had the same problem, mine was a little different though I did not have a package name. My problem was the Class Path for example:

C:\Java Example>java -cp . HelloWorld 

The -cp option for Java and from what I can tell from my experience (not much) but I encountered the error about 20 times trying different methods and until I declared the class Path I was receiving the same error. Vishrant was correct in stating that . represents current directory.

If you need more information about the java options enter java -? or java -help I think the options are not optional.

I just did some more research I found a website that goes into detail about CLASSPATH. The CLASSPATH must be set as an environment variable; to the current directory <.>. You can set it from the command line in windows:

// Set CLASSPATH to the current directory '.'
prompt> set CLASSPATH=.

When you add a new environment setting you need to reboot before enabling the variable. But from the command prompt you can set it. It also can be set like I mentioned at the beginning. For more info, and if your using a different OS, check: Environment Variables.

scanf("%s",str) scans only until it finds a whitespace character. With the input "A 1", it will scan only the first character, hence s2 points at the garbage that happened to be in str, since that array wasn't initialised.

According to the documentation (emphasis mine):

Parses the string argument as a boolean. The boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string "true".

I didn't think this was possible: I had to delete flutter folder and reinstall it from scratch!

Updated 10-second countdown using Hooks (a new feature proposal that lets you use state and other React features without writing a class. They’re currently in React v16.7.0-alpha).

import React, { useState, useEffect } from 'react';
import ReactDOM from 'react-dom';

const Clock = () => {
    const [currentCount, setCount] = useState(10);
    const timer = () => setCount(currentCount - 1);

    useEffect(
        () => {
            if (currentCount <= 0) {
                return;
            }
            const id = setInterval(timer, 1000);
            return () => clearInterval(id);
        },
        [currentCount]
    );

    return <div>{currentCount}</div>;
};

const App = () => <Clock />;

ReactDOM.render(<App />, document.getElementById('root'));

The rouine is pretty good, however it causes my app to hang, so I needed to add the case:

  <xsl:when test="$text = '' or $replace = ''or not($replace)" >
    <xsl:value-of select="$text" />
    <!-- Prevent thsi routine from hanging -->
  </xsl:when>

before the function gets called recursively.

I got the answer from here: When test hanging in an infinite loop

Thank you!

alternative to stdbuf is awk '{print} END {fflush()}' I wish there were a bash builtin to do this. Normally it shouldn't be necessary, but with older versions there might be bash synchronization bugs on file descriptors.

This way works well for me:

1. Add onSubmit attribute in your form, don't forget to include return in the value.

   <form id='frm-contact' method='POST' action='' onSubmit="return contact()">
   

2. Define the function.

   function contact(params) {
       $.ajax({
           url: 'sendmail.php',
           type: "POST",
           dataType: "json",
           timeout: 5000,
           data: { params:params },
           success: function (data, textStatus, jqXHR) {
               // callback
           },
           error: function(jqXHR, textStatus, errorThrown) {
               console.log(jqXHR.responseText);
           }
       });
   
       return false;
   }
   

The sumplest solution is:

From the project dir:

sudo chmod 777 -R .git/objects

Should be

private ArrayList<String[]> action = new ArrayList<String[]>();
action.add(new String[2]);
...

You can't specify the size of the array within the generic parameter, only add arrays of specific size to the list later. This also means that the compiler can't guarantee that all sub-arrays be of the same size, it must be ensured by you.

A better solution might be to encapsulate this within a class, where you can ensure the uniform size of the arrays as a type invariant.

It sometimes happen even when we stop running processes in IDE with help of Red button , we continue to get same error.

It was resolved with following steps,

1. Check what processes are running at available ports

   netstat -ao |find /i "listening"

   We get following

   TCP 0.0.0.0:7981 machinename:0 LISTENING 2428 TCP 0.0.0.0:7982 machinename:0 LISTENING 2428 TCP 0.0.0.0:8080 machinename:0 LISTENING 12704 TCP 0.0.0.0:8500 machinename:0 LISTENING 2428

   i.e. Port Numbers and what Process Id they are listening to

2. Stop process running at your port number(In this case it is 8080 & Process Id is 12704)

   Taskkill /F /IM 12704 (Note: Mention correct Process Id)

For more information follow these links Link1 and Link2.

My Issue was resolved with this, Hope this helps !

string result = myList.FirstOrDefault(x => x == myString)
if(result != null)
{
  //found
}

Here's what I ended up doing:

Obj.writeToStream(toWrite, os);
try {
    String out = new String(os.toByteArray(), "UTF-8");
    assertTrue(out.contains("testString"));
} catch (UnsupportedEncondingException e) {
    fail("Caught exception: " + e.getMessage());
}

Where os is a ByteArrayOutputStream.

Simply type conda update pandas in your preferred shell (on Windows, use cmd; if Anaconda is not added to your PATH use the Anaconda prompt). You can of course use Eclipse together with Anaconda, but you need to specify the Python-Path (the one in the Anaconda-Directory). See this document for a detailed instruction.

You can save the JavaScript into local files:

• https://www.youtube.com/player_api
• https://s.ytimg.com/yts/jsbin/www-widgetapi-vfluxKqfs/www-widgetapi.js

Into the first file, player_api put this code:

if(!window.YT)var YT={loading:0,loaded:0};if(!window.YTConfig)var YTConfig={host:"https://www.youtube.com"};YT.loading||(YT.loading=1,function(){var o=[];YT.ready=function(n){YT.loaded?n():o.push(n)},window.onYTReady=function(){YT.loaded=1;for(var n=0;n<o.length;n++)try{o[n]()}catch(i){}},YT.setConfig=function(o){for(var n in o)o.hasOwnProperty(n)&&(YTConfig[n]=o[n])}}());

Into the second file, find the code: this.a.contentWindow.postMessage(a,b[c]);

and replace it with:

if(this._skiped){
    this.a.contentWindow.postMessage(a,b[c]); 
}
this._skiped = true;

Of course, you can concatenate into one file - will be more efficient. This is not a perfect solution, but it's works!

If you don't mind a Perl one-liner:

$ perl -CS -E 'say "\x{2620}"'
?

-CS enables UTF-8 decoding on input and UTF-8 encoding on output. -E evaluates the next argument as Perl, with modern features like say enabled. If you don't want a newline at the end, use print instead of say.

If you want a true O(n) algorithm, as opposed to O(kn) or something like that, then you should use quickselect (it's basically quicksort where you throw out the partition that you're not interested in). My prof has a great writeup, with the runtime analysis: (reference)

The QuickSelect algorithm quickly finds the k-th smallest element of an unsorted array of n elements. It is a RandomizedAlgorithm, so we compute the worst-case expected running time.

Here is the algorithm.

QuickSelect(A, k)
  let r be chosen uniformly at random in the range 1 to length(A)
  let pivot = A[r]
  let A1, A2 be new arrays
  # split into a pile A1 of small elements and A2 of big elements
  for i = 1 to n
    if A[i] < pivot then
      append A[i] to A1
    else if A[i] > pivot then
      append A[i] to A2
    else
      # do nothing
  end for
  if k <= length(A1):
    # it's in the pile of small elements
    return QuickSelect(A1, k)
  else if k > length(A) - length(A2)
    # it's in the pile of big elements
    return QuickSelect(A2, k - (length(A) - length(A2))
  else
    # it's equal to the pivot
    return pivot

What is the running time of this algorithm? If the adversary flips coins for us, we may find that the pivot is always the largest element and k is always 1, giving a running time of

T(n) = Theta(n) + T(n-1) = Theta(n2)

But if the choices are indeed random, the expected running time is given by

T(n) <= Theta(n) + (1/n) ?i=1 to nT(max(i, n-i-1))

where we are making the not entirely reasonable assumption that the recursion always lands in the larger of A1 or A2.

Let's guess that T(n) <= an for some a. Then we get

T(n) 
 <= cn + (1/n) ?i=1 to nT(max(i-1, n-i))
 = cn + (1/n) ?i=1 to floor(n/2) T(n-i) + (1/n) ?i=floor(n/2)+1 to n T(i)
 <= cn + 2 (1/n) ?i=floor(n/2) to n T(i)
 <= cn + 2 (1/n) ?i=floor(n/2) to n ai

and now somehow we have to get the horrendous sum on the right of the plus sign to absorb the cn on the left. If we just bound it as 2(1/n) ?i=n/2 to n an, we get roughly 2(1/n)(n/2)an = an. But this is too big - there's no room to squeeze in an extra cn. So let's expand the sum using the arithmetic series formula:

?i=floor(n/2) to n i  
 = ?i=1 to n i - ?i=1 to floor(n/2) i  
 = n(n+1)/2 - floor(n/2)(floor(n/2)+1)/2  
 <= n2/2 - (n/4)2/2  
 = (15/32)n2

where we take advantage of n being "sufficiently large" to replace the ugly floor(n/2) factors with the much cleaner (and smaller) n/4. Now we can continue with

cn + 2 (1/n) ?i=floor(n/2) to n ai,
 <= cn + (2a/n) (15/32) n2
 = n (c + (15/16)a)
 <= an

provided a > 16c.

This gives T(n) = O(n). It's clearly Omega(n), so we get T(n) = Theta(n).

The poster's second comment from September 21st is spot on. For those who may be coming to this thread later with the same problem as the poster, here is a brief explanation. The other answers are good to keep in mind, but do not address the common issue encountered by this code.

In Swift, declarations made with the let keyword are constants. Of course if you were going to add items to an array, the array can't be declared as a constant, but a segmented control should be fine, right?! Not if you reference the completed segmented control in its declaration.

Referencing the object (in this case a UISegmentedControl, but this also happens with UIButton) in its declaration when you say .addTarget and let the target be self, things crash. Why? Because self is in the midst of being defined. But we do want to define behaviour as part of the object... Declare it lazily as a variable with var. The lazy fools the compiler into thinking that self is well defined - it silences your compiler from caring at the time of declaration. Lazily declared variables don't get set until they are first called. So in this situation, lazy lets you use the notion of self without issue while you set up the object, and then when your object gets a .touchUpInside or .valueChanged or whatever your 3rd argument is in your .addTarget(), THEN it calls on the notion of self, which at that point is fully established and totally prepared to be a valid target. So it lets you be lazy in declaring your variable. In cases like these, I think they could give us a keyword like necessary, but it is generally seen as a lazy, sloppy practice and you don't want to use it all over your code, though it may have its place in this sort of situation. What it

There is no lazy let in Swift (no lazy for constants).

Here is the Apple documentation on lazy.

Here is the Apple on variables and constants. There is a little more in their Language Reference under Declarations.

import java.util.HashMap;
import java.util.Scanner;


public class HashMapDemo {

    public static void main(String[] args) {
        //Create HashMap object to Store Element as Key and Value 
        HashMap<Character,Integer> hm= new HashMap<Character,Integer>();
        //Enter Your String From Console
        System.out.println("Enter an String:");
        //Create Scanner Class Object From Retrive the element from console to our java application
        Scanner sc = new Scanner(System.in);
        //Store Data in an string format
        String s1=sc.nextLine();
        //find the length of an string and check that hashmap object contain the character or not by using 
        //containskey() if that map object contain element only one than count that value as one or if it contain more than one than increment value 

        for(int i=0;i<s1.length();i++){
            if(!hm.containsKey(s1.charAt(i))){
                hm.put(s1.charAt(i),(Integer)1);
            }//if
            else{
                hm.put(s1.charAt(i),hm.get(s1.charAt(i))+1);

    }//main
}//HashMapDemo

Here's how I solved the problem today after hours of trying all of these different solutions - (for anyone looking for another way still).

Open 2 instances of cmd at your quickstart dir:

window #1:

npm run build:watch

then...

window #2:

npm run serve

It will then open in the browser and work as expected

window.location sets the URL of your current window. To open a new window, you need to use window.open. This should work:

function ToKey(){
    var key = document.tokey.key.value.toLowerCase();
    if (key == "smk") {
        window.open('http://www.smkproduction.eu5.org', '_blank');
    } else {
        alert("Kodi nuk është valid!");
    }
}

Use:

if (containerObject.has("video")) {
    //get value of video
}

Use following layerlist:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
    <item>
        <shape android:shape="rectangle" android:padding="10dp">
            <corners
                 android:bottomRightRadius="5dp"
                 android:bottomLeftRadius="5dp"
                 android:topLeftRadius="5dp"
                 android:topRightRadius="5dp"/>
         </shape>
   </item>
   <item android:drawable="@drawable/image_name_here" />
</layer-list>

You can use iter to process lines as soon as the command outputs them: lines = iter(fd.readline, ""). Here's a full example showing a typical use case (thanks to @jfs for helping out):

from __future__ import print_function # Only Python 2.x
import subprocess

def execute(cmd):
    popen = subprocess.Popen(cmd, stdout=subprocess.PIPE, universal_newlines=True)
    for stdout_line in iter(popen.stdout.readline, ""):
        yield stdout_line 
    popen.stdout.close()
    return_code = popen.wait()
    if return_code:
        raise subprocess.CalledProcessError(return_code, cmd)

# Example
for path in execute(["locate", "a"]):
    print(path, end="")

If you want to remove EVERYTHING :

textarea {
    border: none;
    background-color: transparent;
    resize: none;
    outline: none;
}

RJSONIO from Omegahat is another package which provides facilities for reading and writing data in JSON format.

rjson does not use S4/S3 methods and so is not readily extensible, but still useful. Unfortunately, it does not used vectorized operations and so is too slow for non-trivial data. Similarly, for reading JSON data into R, it is somewhat slow and so does not scale to large data, should this be an issue.

Update (new Package 2013-12-03):

jsonlite: This package is a fork of the RJSONIO package. It builds on the parser from RJSONIO but implements a different mapping between R objects and JSON strings. The C code in this package is mostly from the RJSONIO Package, the R code has been rewritten from scratch. In addition to drop-in replacements for fromJSON and toJSON, the package has functions to serialize objects. Furthermore, the package contains a lot of unit tests to make sure that all edge cases are encoded and decoded consistently for use with dynamic data in systems and applications.

Example - sending some data encoded as JSON as a POST data:

import json
import urllib2
data = json.dumps([1, 2, 3])
f = urllib2.urlopen(url, data)
response = f.read()
f.close()

To remove the hash, you may try using this function

function remove_hash_from_url()
{
    var uri = window.location.toString();
    if (uri.indexOf("#") > 0) {
        var clean_uri = uri.substring(0, uri.indexOf("#"));
        window.history.replaceState({}, document.title, clean_uri);
    }
}

Experienced this on ubuntu 16.04 running PHP 7.1.14. To resolve,first put this in a script and execute. It will return true if curl is installed and enabled,otherwise, it will return false.

<?php
    var_dump(extension_loaded('curl'));
?>

If it returns false, run

sudo apt-get install php7.1-curl

And finally,

sudo service apache2 restart

After the restart, the script will return true and hopefully, your error should be resolved.

Simplest ever solution for TextBox Validation in VB.NET

First, add new VB code file in your project.

1. Go To Solution Explorer
2. Right Click to your project
3. Select Add > New item...
4. Add new VB code file (i.e. example.vb)

or press Ctrl+Shift+A

COPY & PASTE following code into this file and give it a suitable name. (i.e. KeyValidation.vb)

Imports System.Text.RegularExpressions
Module Module1
    Public Enum ValidationType
        Only_Numbers = 1
        Only_Characters = 2
        Not_Null = 3
        Only_Email = 4
        Phone_Number = 5
    End Enum
    Public Sub AssignValidation(ByRef CTRL As Windows.Forms.TextBox, ByVal Validation_Type As ValidationType)
        Dim txt As Windows.Forms.TextBox = CTRL
        Select Case Validation_Type
            Case ValidationType.Only_Numbers
                AddHandler txt.KeyPress, AddressOf number_Leave
            Case ValidationType.Only_Characters
                AddHandler txt.KeyPress, AddressOf OCHAR_Leave
            Case ValidationType.Not_Null
                AddHandler txt.Leave, AddressOf NotNull_Leave
            Case ValidationType.Only_Email
                AddHandler txt.Leave, AddressOf Email_Leave
            Case ValidationType.Phone_Number
                AddHandler txt.KeyPress, AddressOf Phonenumber_Leave
        End Select
    End Sub
    Public Sub number_Leave(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
        Dim numbers As Windows.Forms.TextBox = sender
        If InStr("1234567890.", e.KeyChar) = 0 And Asc(e.KeyChar) <> 8 Or (e.KeyChar = "." And InStr(numbers.Text, ".") > 0) Then
            e.KeyChar = Chr(0)
            e.Handled = True
        End If
    End Sub
    Public Sub Phonenumber_Leave(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
        Dim numbers As Windows.Forms.TextBox = sender
        If InStr("1234567890.()-+ ", e.KeyChar) = 0 And Asc(e.KeyChar) <> 8 Or (e.KeyChar = "." And InStr(numbers.Text, ".") > 0) Then
            e.KeyChar = Chr(0)
            e.Handled = True
        End If
    End Sub
    Public Sub OCHAR_Leave(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
        If InStr("1234567890!@#$%^&*()_+=-", e.KeyChar) > 0 Then
            e.KeyChar = Chr(0)
            e.Handled = True
        End If
    End Sub
    Public Sub NotNull_Leave(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim No As Windows.Forms.TextBox = sender
        If No.Text.Trim = "" Then
            MsgBox("This field Must be filled!")
            No.Focus()
        End If
    End Sub
    Public Sub Email_Leave(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim Email As Windows.Forms.TextBox = sender
        If Email.Text <> "" Then
            Dim rex As Match = Regex.Match(Trim(Email.Text), "^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,3})$", RegexOptions.IgnoreCase)
            If rex.Success = False Then
                MessageBox.Show("Please Enter a valid Email Address", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information)
                Email.BackColor = Color.Red
                Email.Focus()
                Exit Sub
            Else
                Email.BackColor = Color.White
            End If
        End If
    End Sub
End Module

Now use following code to Form Load Event like below.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        AssignValidation(Me.TextBox1, ValidationType.Only_Digits)
        AssignValidation(Me.TextBox2, ValidationType.Only_Characters)
        AssignValidation(Me.TextBox3, ValidationType.No_Blank)
        AssignValidation(Me.TextBox4, ValidationType.Only_Email)
End Sub

Done..!

Just came acreoss this, and since I had the same issue, I'd just post the results I came up with

when parsing, you could update the offset (ie I am parsing a data (1.1.2014) and I only want the date, 1st Jan 2014. On GMT+1 I'd get 31.12.2013. So I offset the value first.

moment(moment.utc('1.1.2014').format());

Well, came in handy for me to support across timezones

Try something like:

from tkinter import Tk, Button, Frame, Entry, END

class ABC(Frame):
    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.pack()        

root = Tk()
app = ABC(master=root)
app.master.title("Simple Prog")
app.mainloop()
root.destroy()

Now you should have a frame with a title, then afterwards you can add windows for different widgets if you like.

Apart from the fantastic answers that were already provided, if it is just a matter of printing out the data you may consider using awk:

awk -F";" '{for (i=1;i<=NF;i++) printf("> [%s]\n", $i)}' <<< "$IN"

This sets the field separator to ;, so that it can loop through the fields with a for loop and print accordingly.

Test

$ IN="[email protected];[email protected]"
$ awk -F";" '{for (i=1;i<=NF;i++) printf("> [%s]\n", $i)}' <<< "$IN"
> [[email protected]]
> [[email protected]]

With another input:

$ awk -F";" '{for (i=1;i<=NF;i++) printf("> [%s]\n", $i)}' <<< "a;b;c   d;e_;f"
> [a]
> [b]
> [c   d]
> [e_]
> [f]

Diagnostics:

You can see which java version Maven uses by running "mvn --version"

Solution for Debian:

The mvn script sets the JAVA_HOME env variable internally by looking for javac (which javac). Therefore, if you have multiple java versions installed concurrently, e.g. JDK 6 and JDK 7 and use the Debian Alternatives system to choose between them, even though you changed the alternative for "java" to JDK 7, mvn will still use JDK 6. You have to change the alternative for "javac", too. E.g.:

# update-alternatives --set javac /usr/lib/jvm/java-7-openjdk-amd64/bin/javac

EDIT:

Actually, an even better solution is to use update-java-alternatives (e.g.)

# update-java-alternatives -s java-1.7.0-openjdk-amd64

as detailed in https://wiki.debian.org/JavaPackage, because this will change all the alternatives to various Java tools (there's a dozen or so).

What you put directly under src/main/java is in the default package, at the root of the classpath. It's the same for resources put under src/main/resources: they end up at the root of the classpath.

So the path of the resource is app-context.xml, not main/resources/app-context.xml.

I had set:

log4j.appender.R=org.apache.log4j.DailyRollingFileAppender
log4j.appender.R.DatePattern='.'yyyy-MM-dd
# Archive log files (Keep one year of daily files)
log4j.appender.R.MaxBackupIndex=367

Like others before me, the DEBUG option showed me the error:

log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.DailyRollingFileAppender.

Here is an idea I have not tried yet, suppose I set the DatePattern such that the files overwrite each other after the required time period. To retain a year's worth I could try setting:

log4j.appender.R.DatePattern='.'MM-dd

Would it work or would it cause an error ? Like that it will take a year to find out, I could try:

log4j.appender.R.DatePattern='.'dd

but it will still take a month to find out.

You could use CONCAT, and the numeric argument of it is converted to its equivalent binary string form.

select t2.* 
from t1 join t2 
on t2.url=CONCAT('site.com/path/%', t1.id, '%/more') where t1.id > 9000

Deleting a null pointer has no effect. It's not good coding style necessarily because it's not needed, but it's not bad either.

If you are searching for good coding practices consider using smart pointers instead so then you don't need to delete at all.

TLS/SSL (The S in HTTPS) guarantees that there are no eavesdroppers between you and the server you are contacting, i.e. no proxies. Normally, you use CONNECT to open up a TCP connection through the proxy. In this case, the proxy will not be able to cache, read, or modify any requests/responses, and therefore be rather useless.

If you want the proxy to be able to read information, you can take the following approach:

1. Client starts HTTPS session
2. Proxy transparently intercepts the connection and returns an ad-hoc generated(possibly weak) certificate K_a, signed by a certificate authority that is unconditionally trusted by the client.
3. Proxy starts HTTPS session to target
4. Proxy verifies integrity of SSL certificate; displays error if the cert is not valid.
5. Proxy streams content, decrypts it and re-encrypts it with K_a
6. Client displays stuff

An example is Squid's SSL bump. Similarly, burp can be configured to do this. This has also been used in a less-benign context by an Egyptian ISP.

Note that modern websites and browsers can employ HPKP or built-in certificate pins which defeat this approach.

There is no installation per se.

You download jQuery and include it in your html files like this:

<script src="jquery.js" type="text/javascript"></script>

Of course, modify the filename so that it's the same as the downloaded script file.

Done!

NSString *deviceType = [UIDevice currentDevice].model;

It's very simple to define a function inside razor.

@functions {

    public static HtmlString OrderedList(IEnumerable<string> items)
    { }
}

So you can call a the function anywhere. Like

@Functions.OrderedList(new[] { "Blue", "Red", "Green" })

However, this same work can be done through helper too. As an example

@helper OrderedList(IEnumerable<string> items){
    <ol>
        @foreach(var item in items){
            <li>@item</li>
        }
    </ol>
}

So what is the difference?? According to this previous post both @helpers and @functions do share one thing in common - they make code reuse a possibility within Web Pages. They also share another thing in common - they look the same at first glance, which is what might cause a bit of confusion about their roles. However, they are not the same. In essence, a helper is a reusable snippet of Razor sytnax exposed as a method, and is intended for rendering HTML to the browser, whereas a function is static utility method that can be called from anywhere within your Web Pages application. The return type for a helper is always HelperResult, whereas the return type for a function is whatever you want it to be.

When you use float without width, there remains some space in that row. To block this space you can use clear:both; in next element.

if string is a variable, use the .repr method on it:

>>> s = '\tgherkin\n'

>>> s
'\tgherkin\n'

>>> print(s)
    gherkin

>>> print(s.__repr__())
'\tgherkin\n'

If someone uses AndroidStudio make sure that the assets folder is placed in

1. app/src/main/assets

   directory.

SELECT datetime('now', 'localtime');

Try this code:

Drawable thumb = ContextCompat.getDrawable(getActivity(), R.mipmap.cir_32);
mSeekBar.setThumb(thumb);

A tree in Python is quite simple. Make a class that has data and a list of children. Each child is an instance of the same class. This is a general n-nary tree.

class Node(object):
    def __init__(self, data):
        self.data = data
        self.children = []

    def add_child(self, obj):
        self.children.append(obj)

Then interact:

>>> n = Node(5)
>>> p = Node(6)
>>> q = Node(7)
>>> n.add_child(p)
>>> n.add_child(q)
>>> n.children
[<__main__.Node object at 0x02877FF0>, <__main__.Node object at 0x02877F90>]
>>> for c in n.children:
...   print c.data
... 
6
7
>>> 

This is a very basic skeleton, not abstracted or anything. The actual code will depend on your specific needs - I'm just trying to show that this is very simple in Python.

I used SCSS, and the fully responsive modal:

.modal-dialog.large {
    @media (min-width: $screen-sm-min) { width:500px; }
    @media (min-width: $screen-md-min) { width:700px; }
    @media (min-width: $screen-lg-min) { width:850px; }
} 

You shouldn't edit it, you should completely scrap it.

Any attempt to make execution stop for a certain amount of time will lock up the browser and switch it to a Not Responding state. The only thing you can do is use setTimeout correctly.

try:
    a # does a exist in the current namespace
except NameError:
    a = 10 # nope

I started by using the answers here, but modified it to use YouTube's new iframe embedding...

$('a.more').on('click', function(event) {
    event.preventDefault();
    $.fancybox({
        'type' : 'iframe',
        // hide the related video suggestions and autoplay the video
        'href' : this.href.replace(new RegExp('watch\\?v=', 'i'), 'embed/') + '?rel=0&autoplay=1',
        'overlayShow' : true,
        'centerOnScroll' : true,
        'speedIn' : 100,
        'speedOut' : 50,
        'width' : 640,
        'height' : 480
    });
});

This is for others who may encounter the following requirements:

1. Completely replace the visual indication of "selected" (e.g. use some kind of shape), beyond just changing the color of the standard highlight
2. Include this selected indication in the DataTemplate along with the other visual representations of your model, but,
3. Don't want to have to add an "IsSelectedItem" property to your model class and be burdened with manually manipulating that property on all model objects.
4. Require items to be selectable in the ListView
5. Also would like to replace the visual representation of IsMouseOver

If you're like me (using WPF with .NET 4.5) and found that the solutions involving style triggers simply didn't work, here's my solution:

Replace the ControlTemplate of the ListViewItem in a style:

<ListView ItemsSource="{Binding MyStrings}" ItemTemplate="{StaticResource dtStrings}">
        <ListView.ItemContainerStyle>
            <Style TargetType="ListViewItem">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="ListViewItem">
                            <ContentPresenter/>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ListView.ItemContainerStyle>
    </ListView>

..And the DataTemplate:

<DataTemplate x:Key="dtStrings">
        <Border Background="LightCoral" Width="80" Height="24" Margin="1">
            <Grid >
                <Border Grid.ColumnSpan="2" Background="#88FF0000" Visibility="{Binding RelativeSource={RelativeSource AncestorType=ListViewItem}, Path=IsMouseOver, Converter={StaticResource conBoolToVisibilityTrueIsVisibleFalseIsCollapsed}}"/>
                <Rectangle Grid.Column="0" Fill="Lime" Width="10" HorizontalAlignment="Left" Visibility="{Binding RelativeSource={RelativeSource AncestorType=ListViewItem}, Path=IsSelected, Converter={StaticResource conBoolToVisibilityTrueIsVisibleFalseIsCollapsed}}" />
                <TextBlock Grid.Column="1" Text="{Binding}" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="White" />
            </Grid>
        </Border>
    </DataTemplate>

Results in this at runtime (item 'B' is selected, item 'D' has mouse over):

try:

[checked]="item.checked"

Just add the following rules to the parent element:

display: flex;
justify-content: center; /* align horizontal */
align-items: center; /* align vertical */

Here's a sample demo (Resize window to see the image align)

Browser support for Flexbox nowadays is quite good.

For cross-browser compatibility for display: flex and align-items, you can add the older flexbox syntax as well:

display: -webkit-box;
display: -webkit-flex;
display: -moz-box;
display: -ms-flexbox;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;

Here's the more concise and easy to read solution based on offset width difference:

function getScrollbarWidth(): number {

  // Creating invisible container
  const outer = document.createElement('div');
  outer.style.visibility = 'hidden';
  outer.style.overflow = 'scroll'; // forcing scrollbar to appear
  outer.style.msOverflowStyle = 'scrollbar'; // needed for WinJS apps
  document.body.appendChild(outer);

  // Creating inner element and placing it in the container
  const inner = document.createElement('div');
  outer.appendChild(inner);

  // Calculating difference between container's full width and the child width
  const scrollbarWidth = (outer.offsetWidth - inner.offsetWidth);

  // Removing temporary elements from the DOM
  outer.parentNode.removeChild(outer);

  return scrollbarWidth;

}

See the JSFiddle.

Imagine you've thread A and thread B. They are both synchronised on the same object and inside this block there's a global variable they are both updating;

static boolean commonVar = false;
Object lock = new Object;

...

void threadAMethod(){
    ...
    while(commonVar == false){
         synchornized(lock){
              ...
              commonVar = true
         }
    }
}

void threadBMethod(){
    ...
    while(commonVar == true){
         synchornized(lock){
              ...
              commonVar = false
         }
    }
}

So, when thread A enters in the while loop and holds the lock, it does what it has to do and set the commonVar to true. Then thread B comes in, enters in the while loop and since commonVar is true now, it is be able to hold the lock. It does so, executes the synchronised block, and sets commonVar back to false. Now, thread A again gets it's new CPU window, it was about to quit the while loop but thread B has just set it back to false, so the cycle repeats over again. Threads do something (so they're not blocked in the traditional sense) but for pretty much nothing.

It maybe also nice to mention that livelock does not necessarily have to appear here. I'm assuming that the scheduler favours the other thread once the synchronised block finish executing. Most of the time, I think it's a hard-to-hit expectation and depends on many things happening under the hood.

If you want to know the number of visitors (as is titled in the question) and not the number of pageviews, then you'll need to create a custom report.

Terminology

Google Analytics has changed the terminology they use within the reports. Now, visits is named "sessions" and unique visitors is named "users."

User - A unique person who has visited your website. Users may visit your website multiple times, and they will only be counted once.

Session - The number of different times that a visitor came to your site.

Pageviews - The total number of pages that a user has accessed.

Creating a Custom Report

1. To create a custom report, click on the "Customization" item in the left navigation menu, and then click on "Custom Reports".

2. The "Create Custom Report" page will open.
3. Enter a name for your report.
4. In the "Metric Groups" section, enter either "Users" or "Sessions" depending on what information you want to collect (see Terminology, above).
5. In the "Dimension Drilldowns" section, enter "Page".
6. Under "Filters" enter the individual page (exact) or group of pages (using regex) that you would like to see the data for.
7. Save the report and run it.

The answer is from https://crontab.guru/every-2-hours. It is interesting.

Yes, image alt text can be styled using any style property you use for regular text, such as font-size, font-weight, line-height, color, background-color,etc. The line-height (of text) or vertical-align (if display:table-cell used) could also be used to vertically align alt text within an image element or image wrapping container, i.e. div.

To prevent accessibility issues regarding contrast, and inheriting the browser's default black font color when you've set a dark blue background-color, always set both the color of your font and its background-color at the same time.

Using the Interop you get a range of cells and call the .Merge() method on that range.

eWSheet.Range[eWSheet.Cells[1, 1], eWSheet.Cells[4, 1]].Merge();

I create a file dif.go that contains your code:

package dif

import (
    "time"
)

var StartTime = time.Now()

Outside the folder I create my main.go, it is ok!

package main

    dif "./dif"
    "fmt"
)

func main() {
    fmt.Println(dif.StartTime)
}

Outputs:

It works!

Objective-C is not Java. In Objective-C exceptions are what they are called. Exceptions! Don’t use them for error handling. It’s not their proposal. Just check the length of the string before using characterAtIndex and everything is fine....

you can simply use this

 startActivity(new Intent(this, Splash.class));
 moveTaskToBack(true);

The startActivity(new Intent(this, Splash.class)); is the first class that will be lauched when the application starts

moveTaskToBack(true); will minimize your application

I will provide really simple solution to the problem. Suppose we have two inputs username and password,but we want our handle to be easy and generic ,so we can reuse it and don't write boilerplate code.

I.Our form:

                <form>
                    <input type="text" name = "username" onChange={this.onChange} value={this.state.username}/>
                    <input type="text" name = "password" onChange={this.onChange} value={this.state.password}/>
                    <br></br>
                    <button type="submit">Submit</button>
                </form>

II.Our constructor ,which we want to save our username and password ,so we can access them easily:

constructor(props) {
    super(props);
    this.state = {
        username: '',
        password: ''
    };

    this.onSubmit = this.onSubmit.bind(this);
    this.onChange = this.onChange.bind(this);
}

III.The interesting and "generic" handle with only one onChange event is based on this:

onChange(event) {
    let inputName = event.target.name;
    let value = event.target.value;

    this.setState({[inputName]:value});


    event.preventDefault();
}

Let me explain:

1.When a change is detected the onChange(event) is called

2.Then we get the name parameter of the field and its value:

let inputName = event.target.name; ex: username

let value = event.target.value; ex: itsgosho

3.Based on the name parameter we get our value from the state in the constructor and update it with the value:

this.state['username'] = 'itsgosho'

4.The key to note here is that the name of the field must match with our parameter in the state

In jQuery, you can do alert($("#theid").css("width")).

-- if you haven't taken a look at jQuery, I highly recommend it; it makes many simple javascript tasks effortless.

for the record, this post is 5 years old. The web has developed, moved on, etc. There are ways to do this with Plain Old Javascript, which is better.

I was having a problem building notifications (only developing for Android 4.0+). This link showed me exactly what I was doing wrong and says the following:

Required notification contents

A Notification object must contain the following:

A small icon, set by setSmallIcon()
A title, set by setContentTitle()
Detail text, set by setContentText()

Basically I was missing one of these. Just as a basis for troubleshooting with this, make sure you have all of these at the very least. Hopefully this will save someone else a headache.

Just after your Page_Load add this:

public override void VerifyRenderingInServerForm(Control control)
{
    //base.VerifyRenderingInServerForm(control);
}

Note that I don't do anything in the function.

If you want to specifically use java ArrayList then you can do something like this:

fun initList(){
    val list: ArrayList<String> = ArrayList()
    list.add("text")
    println(list)
}

Otherwise @guenhter answer is the one you are looking for.

A library and demo with the complete source code for scrolling toolbars or any type of header can be downloaded here:

https://github.com/JohannBlake/JBHeaderScroll

Headers can be Toolbars, LinearLayouts, RelativeLayouts, or whatever type of view you use to create a header.

The scrollable area can be any type of scroll content including ListView, ScrollView, WebView, RecyclerView, RelativeLayout, LinearLayout or whatever you want.

There's even support for nested headers.

It is indeed a complex undertaking to synchronize headers (toolbars) and scrollable content the way it's done in Google Newsstand.

This library doesn't require implementing any kind of onScrollListener.

The solutions listed above by others are only half baked solutions that don't take into consideration that the top edge of the scrollable content area beneath the toolbar has to initially be aligned to the bottom edge of the toolbar and then during scrolling the content area needs to be repositioned and possibly resized. The JBHeaderScroll handles all these issues.

The python code you write is compiled into python bytecode, which creates file with extension .pyc. If compiles, again question is, why not compiled language.

Note that this isn't compilation in the traditional sense of the word. Typically, we’d say that compilation is taking a high-level language and converting it to machine code. But it is a compilation of sorts. Compiled in to intermediate code not into machine code (Hope you got it Now).

Back to the execution process, your bytecode, present in pyc file, created in compilation step, is then executed by appropriate virtual machines, in our case, the CPython VM The time-stamp (called as magic number) is used to validate whether .py file is changed or not, depending on that new pyc file is created. If pyc is of current code then it simply skips compilation step.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

string firstdayofyear = new DateTime(DateTime.Now.Year, 1, 1).ToString("MM-dd-yyyy");
string lastdayofyear = new DateTime(DateTime.Now.Year, 12, 31).ToString("MM-dd-yyyy");
string firstdayofmonth = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1).ToString("MM-dd-yyyy");
string lastdayofmonth = new DateTime(DateTime.Now.Year, DateTime.Now.Month, 1).AddMonths(1).AddDays(-1).ToString("MM-dd-yyyy");

How about:

writing-mode:tb-rl

Where top->bottom, right->left?

We will need vertical rule for this.

Dim fileEntries As String() = Directory.GetFiles("YourPath", "*.txt")
' Process the list of .txt files found in the directory. '
Dim fileName As String

For Each fileName In fileEntries
    If (System.IO.File.Exists(fileName)) Then
        'Read File and Print Result if its true
        ReadFile(fileName)
    End If
    TransfereFile(fileName, 1)
Next

If you are on Rails 4 and you get this error, it could happen if you are using enum on the model if you've defined with symbols like this:

class User
  enum preferred_phone: [:home_phone, :mobile_phone, :work_phone]
end

The form will pass say a radio selector as a string param. That's what happened in my case. The simple fix is to change enum to strings instead of symbols

enum preferred_phone: %w[home_phone mobile_phone work_phone]
# or more verbose
enum preferred_phone: ['home_phone', 'mobile_phone', 'work_phone']

The format string attack on printf you mentioned isn't specific to the "%x" formatting - in any case where printf has more formatting parameters than passed variables, it will read values from the stack that do not belong to it. You will get the same issue with %d for example. %x is useful when you want to see those values as hex.

As explained in previous answers, %08x will produce a 8 digits hex number, padded by preceding zeros.

Using the formatting in your code example in printf, with no additional parameters:

printf ("%08x %08x %08x %08x");

Will fetch 4 parameters from the stack and display them as 8-digits padded hex numbers.

Go to Build > Clean Project

Build your project again.

Try this:

<a onclick='$("#notification").fadeOut(300, function() { $(this).remove(); });' class="notificationClose "><img src="close.png"/></a>

I think your double quotes around the onclick were making it not work. :)

EDIT: As pointed out below, inline javascript is evil and you should probably take this out of the onclick and move it to jQuery's click() event handler. That is how the cool kids are doing it nowadays.

Or using regular expressions

"rmlike" <- function(...) {
  names <- sapply(
    match.call(expand.dots = FALSE)$..., as.character)
  names = paste(names,collapse="|")
  Vars <- ls(1)
  r <- Vars[grep(paste("^(",names,").*",sep=""),Vars)]
  rm(list=r,pos=1)
}

rmlike(temp)

I like this approach because it is simple and clean:

    String getCompaniesIdAndName = " select "
            + " c.id as id, "
            + " c.name as name "
            + " from Company c ";

    @Query(value = getCompaniesWithoutAccount)
    Set<CompanyIdAndName> findAllIdAndName();

    public static interface CompanyIdAndName extends DTO {
        Integer getId();

        String getName();

    }

You can use display: table-cell property as in the following code:

div {
     height: 100%;
     display: table-cell; 
     vertical-align: middle;
    }

The source for this answer is the comment to the answer at: Will docker container auto sync time with the host machine?

After looking at the answer, I realized that there is no way a clock drift will occur on the docker container. Docker uses the same clock as the host and the docker cannot change it. It means that doing an ntpdate inside the docker does not work.

The correct thing to do is to update the host time using ntpdate

As far as syncing timezones is concerned, -v /etc/localtime:/etc/localtime:ro works.

Here is a useful git alias that works for me.

git config --global alias.tree '! git ls-tree --full-name --name-only -t -r HEAD | sed -e "s/[^-][^\/]*\//   |/g" -e "s/|\([^ ]\)/|-- \1/"'

Here is the output of git tree

Clearly tree has better output, but I would like it to use my .gitignore file. So that my compiled content doesn't show

To complement Jon Lin's answer, here is a no-trailing-slash technique that also works if the website is located in a directory (like example.org/blog/):

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [R=301,L]

For the sake of completeness, here is an alternative emphasizing that REQUEST_URI starts with a slash (at least in .htaccess files):

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} /(.*)/$
RewriteRule ^ /%1 [R=301,L] <-- added slash here too, don't forget it

Just don't use %{REQUEST_URI} (.*)/$. Because in the root directory REQUEST_URI equals /, the leading slash, and it would be misinterpreted as a trailing slash.

./gradlew

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

Yes, you can do this quite easily. Click on your project in the project explorer or Navigator, go to the Search menu at the top, click File..., input your search string, and make sure that 'Selected Resources' or 'Enclosing Projects' is selected, then hit search. The alternative way to open the window is with Ctrl-H. This may depend on your keyboard accelerator configuration.

_{(source: avajava.com)}

You can also use this approach in case you want to pass some http parameters and send a json request:

(note: I have added in some extra code just incase it helps any other future readers)

public void postJsonWithHttpParams() throws URISyntaxException, UnsupportedEncodingException, IOException {

    //add the http parameters you wish to pass
    List<NameValuePair> postParameters = new ArrayList<>();
    postParameters.add(new BasicNameValuePair("param1", "param1_value"));
    postParameters.add(new BasicNameValuePair("param2", "param2_value"));

    //Build the server URI together with the parameters you wish to pass
    URIBuilder uriBuilder = new URIBuilder("http://google.ug");
    uriBuilder.addParameters(postParameters);

    HttpPost postRequest = new HttpPost(uriBuilder.build());
    postRequest.setHeader("Content-Type", "application/json");

    //this is your JSON string you are sending as a request
    String yourJsonString = "{\"str1\":\"a value\",\"str2\":\"another value\"} ";

    //pass the json string request in the entity
    HttpEntity entity = new ByteArrayEntity(yourJsonString.getBytes("UTF-8"));
    postRequest.setEntity(entity);

    //create a socketfactory in order to use an http connection manager
    PlainConnectionSocketFactory plainSocketFactory = PlainConnectionSocketFactory.getSocketFactory();
    Registry<ConnectionSocketFactory> connSocketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
            .register("http", plainSocketFactory)
            .build();

    PoolingHttpClientConnectionManager connManager = new PoolingHttpClientConnectionManager(connSocketFactoryRegistry);

    connManager.setMaxTotal(20);
    connManager.setDefaultMaxPerRoute(20);

    RequestConfig defaultRequestConfig = RequestConfig.custom()
            .setSocketTimeout(HttpClientPool.connTimeout)
            .setConnectTimeout(HttpClientPool.connTimeout)
            .setConnectionRequestTimeout(HttpClientPool.readTimeout)
            .build();

    // Build the http client.
    CloseableHttpClient httpclient = HttpClients.custom()
            .setConnectionManager(connManager)
            .setDefaultRequestConfig(defaultRequestConfig)
            .build();

    CloseableHttpResponse response = httpclient.execute(postRequest);

    //Read the response
    String responseString = "";

    int statusCode = response.getStatusLine().getStatusCode();
    String message = response.getStatusLine().getReasonPhrase();

    HttpEntity responseHttpEntity = response.getEntity();

    InputStream content = responseHttpEntity.getContent();

    BufferedReader buffer = new BufferedReader(new InputStreamReader(content));
    String line;

    while ((line = buffer.readLine()) != null) {
        responseString += line;
    }

    //release all resources held by the responseHttpEntity
    EntityUtils.consume(responseHttpEntity);

    //close the stream
    response.close();

    // Close the connection manager.
    connManager.close();
}

Try reading the InputStream of the runtime:

Runtime rt = Runtime.getRuntime();
String[] commands = {"system.exe", "-send", argument};
Process proc = rt.exec(commands);
BufferedReader br = new BufferedReader(
    new InputStreamReader(proc.getInputStream()));
String line;
while ((line = br.readLine()) != null)
    System.out.println(line);

You might also need to read the error stream (proc.getErrorStream()) if the process is printing error output. You can redirect the error stream to the input stream if you use ProcessBuilder.

I am using OSX -v 10.10.4. The solution above is a quick & easy.

Happening OSX does not have the connection library by default.

First you should install the connector:

brew install mysql-connector-c

Then install with pip mysql

pip install mysql-python

The OP did not ask for cleanup for all remotes, rather for all branches of default remote.

So git fetch --prune is what should be used.

Setting git config remote.origin.prune true makes --prune automatic. In that case just git fetch will also prune stale remote branches from the local copy. See also Automatic prune with Git fetch or pull.

Note that this does not clean local branches that are no longer tracking a remote branch. See How to prune local tracking branches that do not exist on remote anymore for that.

If you're looking for a good alias to do this plus not blow up cd if you aren't in a git dir:

alias ..g='git rev-parse && cd "$(git rev-parse --show-cdup)"'

This is an answer to the comment posted by erikkallen:

You don't need a temp table. If you only have a few rows, (SELECT 1 FROM dual UNION SELECT 2 FROM dual) will do. Why would your example give ORA-0001? Wouldn't merge take the update lock on the index key and not continue until Sess1 has either committed or rolled back? – erikkallen

Well, try it yourself and tell me whether you get the same error or not:

SESS1:

create table t1 (pk int primary key, i int);
create table t11 (pk int primary key, i int);
insert into t1 values(1, 1);
insert into t11 values(2, 21);
insert into t11 values(3, 31);
commit;

SESS2: insert into t1 values(2, 2);

SESS1:

MERGE INTO t1 d
USING t11 s ON (d.pk = s.pk)
WHEN NOT MATCHED THEN INSERT (d.pk, d.i) VALUES (s.pk, s.i);

SESS2: commit;

SESS1: ORA-00001

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors at your server side.

You can fetch request using mode: 'cors'. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.

So in both condition you need to configure cors in your server or you need to use custom proxy server.

Like others already wrote, in short:

shared project
reuse on the code (file) level, allowing for folder structure and resources as well

pcl
reuse on the assembly level

What was mostly missing from answers here for me is the info on reduced functionality available in a PCL: as an example you have limited file operations (I was missing a lot of File.IO fuctionality in a Xamarin cross-platform project).

In more detail
shared project:
+ Can use #if when targeting multiple platforms (e. g. Xamarin iOS, Android, WinPhone)
+ All framework functionality available for each target project (though has to be conditionally compiled)
o Integrates at compile time
- Slightly larger size of resulting assemblies
- Needs Visual Studio 2013 Update 2 or higher

pcl:
+ generates a shared assembly
+ usable with older versions of Visual Studio (pre-2013 Update 2)
o dynamically linked
- lmited functionality (subset of all projects it is being referenced by)

If you have the choice, I would recommend going for shared project, it is generally more flexible and more powerful. If you know your requirements in advance and a PCL can fulfill them, you might go that route as well. PCL also enforces clearer separation by not allowing you to write platform-specific code (which might not be a good choice to be put into a shared assembly in the first place).

Main focus of both is when you target multiple platforms, else you would normally use just an ordinary library/dll project.

In addition to above differences following are few more:

1. RV separates view creation and binding of data to view. In LV, you need to check if convertView is null or not for creating view, before binding data to it. So, in case of RV, view will be created only when it is needed but in case of LV, one can miss the check for convertview and will create view everytime.

2. Switching between Grid and List is more easy now with LayoutManager.

3. No need to notify and update all items, even if only single item is changed.

4. One had to implement view caching in case of LV. It is provided in RV by default. (There is difference between view caching n recycling.)

5. Very easy item animations in case of RV.

Have you checked your hidden input field where the token is generated?

If it is null then your token is not returned by csrf_token function.You have to write your route that renders the form inside the middleware group provide by laravel as follows:

  Route::group(['middleware' => 'web'], function () {
Route::get('/', function () {
    return view('welcome');
});

Here root route contains my sign up page which requires csrf token. This token is managed by laravel 5.2.7 inside 'web' middleware in kernel.php.

Do not forget to insert {!! csrf_field() !!} inside the form..

Yes, SQL Server 2012 supports multiple inserts - that feature was introduced in SQL Server 2008.

That makes me wonder if you have Management Studio 2012, but you're really connected to a SQL Server 2005 instance ...

What version of the SQL Server engine do you get from SELECT @@VERSION ??

A quick solution:

First, exclude the package: Right click on the source package >> Build Path >> Exclude

Then include it back: Right click on the source package >> Build Path >> Include

Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.

You might not be able to change npm registry using .bat file as Gntem pointed out. But I understand that you need the ability to automate changing registries. You can do so by having your .npmrc configs in separate files (say npmrc_jfrog & npmrc_default) and have your .bat files do the copying task.

For example (in Windows): Your default_registry.bat will have

xcopy /y npmrc_default .npmrc

and your jfrog_registry.bat will have

xcopy /y npmrc_jfrog .npmrc

Note: /y suppresses prompting to confirm that you want to overwrite an existing destination file.

This will make sure that all the config properties (registry, proxy, apiKeys, etc.) get copied over to .npmrc.

You can read more about xcopy here.

/* I have done it this way, and also tested it */

Step 1 = Register custom cell class (in case of prototype cell in table) or nib (in case of custom nib for custom cell) for table like this in viewDidLoad method:

[self.yourTableView registerClass:[CustomTableViewCell class] forCellReuseIdentifier:@"CustomCell"];

OR

[self.yourTableView registerNib:[UINib nibWithNibName:@"CustomTableViewCell" bundle:nil] forCellReuseIdentifier:@"CustomCell"];

Step 2 = Use UITableView's "dequeueReusableCellWithIdentifier: forIndexPath:" method like this (for this, you must register class or nib) :

   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
            CustomTableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"CustomCell" forIndexPath:indexPath];

            cell.imageViewCustom.image = nil; // [UIImage imageNamed:@"default.png"];
            cell.textLabelCustom.text = @"Hello";

            dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
                // retrive image on global queue
                UIImage * img = [UIImage imageWithData:[NSData dataWithContentsOfURL:     [NSURL URLWithString:kImgLink]]];

                dispatch_async(dispatch_get_main_queue(), ^{

                    CustomTableViewCell * cell = (CustomTableViewCell *)[tableView cellForRowAtIndexPath:indexPath];
                  // assign cell image on main thread
                    cell.imageViewCustom.image = img;
                });
            });

            return cell;
        }

Try changing it to.

 Response.Clear();
 Response.ClearHeaders();
 Response.ClearContent();
 Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
 Response.AddHeader("Content-Length", file.Length.ToString());
 Response.ContentType = "text/plain";
 Response.Flush();
 Response.TransmitFile(file.FullName);
 Response.End();

For general check if there was a POST action use:

if (!empty($_POST))

EDIT: As stated in the comments, this method won't work for in some cases (e.g. with check boxes and button without a name). You really should use:

if ($_SERVER['REQUEST_METHOD'] == 'POST')

If MySQLdb's now distributed in a way that requires setuptools, your choices are either to download the latter (e.g. from here) or refactor MySQLdb's setup.py to bypass setuptools (maybe just importing setup and Extension from plain distutils instead might work, but you may also need to edit some of the setup_*.py files in the same directory).

Depending on how your site's Python installation is configured, installing extensions for your own individual use without requiring sysadm rights may be hard, but it's never truly impossible if you have shell access. You'll need to tweak your Python's sys.path to start with a directory of your own that's your personal equivalent of the system-wide site pacages directory, e.g. by setting PYTHONPATH persistently in your own environment, and then manually place in said personal directory what normal installs would normally place in site-packages (and/or subdirectories thereof).

Your arguments are in the wrong order. Try git commit -m 'my notes' path/to/my/file.ext, or if you want to be more explicit, git commit -m 'my notes' -- path/to/my/file.ext.

Incidentally, git v1.5.2.1 is 4.5 years old. You may want to update to a newer version (1.7.8.3 is the current release).

readline is for string.. just use read

Mostly we write below statement select * from table where length(ltrim(rtrim(field)))=10;

ORA-06512 is part of the error stack. It gives us the line number where the exception occurred, but not the cause of the exception. That is usually indicated in the rest of the stack (which you have still not posted).

In a comment you said

"still, the error comes when pNum is not between 12 and 14; when pNum is between 12 and 14 it does not fail"

Well, your code does this:

IF ((pNum < 12) OR (pNum > 14)) THEN     
    RAISE vSOME_EX;

That is, it raises an exception when pNum is not between 12 and 14. So does the rest of the error stack include this line?

ORA-06510: PL/SQL: unhandled user-defined exception

If so, all you need to do is add an exception block to handle the error. Perhaps:

PROCEDURE PX(pNum INT,pIdM INT,pCv VARCHAR2,pSup FLOAT)
AS
    vSOME_EX EXCEPTION;

BEGIN 
    IF ((pNum < 12) OR (pNum > 14)) THEN     
        RAISE vSOME_EX;
    ELSE  
        EXECUTE IMMEDIATE  'INSERT INTO M'||pNum||'GR (CV, SUP, IDM'||pNum||') VALUES('||pCv||', '||pSup||', '||pIdM||')';
    END IF;
exception
    when vsome_ex then
         raise_application_error(-20000
                                 , 'This is not a valid table:  M'||pNum||'GR');

END PX;

The documentation covers handling PL/SQL exceptions in depth.

URL url = new File("src/main/java/ua/adeptius/goit/sample.fxml").toURI().toURL();
Parent root = FXMLLoader.load(url);

That is helped for me because

getClass.getResource("path")

always returns me null;

In the layout (app/design/frontend/your_theme/layout/default.xml):

<default>
    <cms_page> <!-- need to be redefined for your needs -->
        <reference name="content">
            <block type="cms/block" name="cms_newest_product" as="cms_newest_product">
                <action method="setBlockId"><block_id>newest_product</block_id></action>
            </block>
        </reference>
    </cms_page>
</default>

In your phtml template:

<?php echo $this->getChildHtml('newest_product'); ?>

Don't forget about cache cleaning.

I think it help.

C# Xamarin version

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

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

        var securityRecords = new[] { SecKind.GenericPassword,
                                    SecKind.Certificate,

        {
            SecRecord query = new SecRecord(recordKind);
            SecKeyChain.Remove(query);
        }

Reason can be Middleware if you forget to put following code to the end of handle function

return $next($request);

or you can simply have

$('.date-pick').datePicker().val(new Date()).trigger('change')

                      Collectors.joining(System.lineSeparator()));
            }

        } catch (IOException ex) {

            content = String.format("Cannot read webpage %s", ex);
            Logger.getLogger(WebPageReader.class.getName()).log(Level.SEVERE, null, ex);
        }

        return content;
    }

    private boolean validateUrl(String webpage) {

        UrlValidator urlValidator = new UrlValidator();

        return urlValidator.isValid(webpage);
    }
}

WebPageReader validates the URL and reads the contents of the web page. It returns a string containing the HTML code of the page.

<!DOCTYPE html>
<html>
    <head>
        <title>Home page</title>
        <meta charset="UTF-8">
    </head>
    <body>
        <form action="ReadWebPage">

            <label for="page">Enter a web page name:</label>
            <input  type="text" id="page" name="webpage">

            <button type="submit">Submit</button>

        </form>
    </body>
</html>

Finally, this is the home page containing the HTML form. This is taken from my tutorial about this topic.

For Data access you can use OData. Here is a demo where Scott Hanselman creates an OData front end to StackOverflow database in 30 minutes, with XML and JSON access: Creating an OData API for StackOverflow including XML and JSON in 30 minutes.

For administrative access, like phpMyAdmin package, there is no well established one. You may give a try to IIS Database Manager.

if you know at least one <style> tag exist in page , use this function :

CSS=function(i){document.getElementsByTagName('style')[0].innerHTML+=i};

usage :

CSS("div{background:#00F}");

The WHERE clause is misplaced, it has to follow the table references and JOIN operations.

Something like this:

 FROM tartikel p1 
 JOIN tartikelpict p2 
   ON p1.kArtikel = p2.kArtikel 
  AND p2.nNr = 1
WHERE p1.dErstellt >= DATE(NOW()) - INTERVAL 7 DAY
ORDER BY p1.kArtikel DESC

EDIT (three plus years later)

The above essentially answers the question "I tried to add a WHERE clause to my query and now the query is returning an error, how do I fix it?"

As to a question about writing a condition that checks a date range of "last 7 days"...

That really depends on interpreting the specification, what the datatype of the column in the table is (DATE or DATETIME) and what data is available... what should be returned.

To summarize: the general approach is to identify a "start" for the date/datetime range, and "end" of that range, and reference those in a query. Let's consider something easier... all rows for "yesterday".

If our column is DATE type. Before we incorporate an expression into a query, we can test it in a simple SELECT

 SELECT DATE(NOW()) + INTERVAL -1 DAY 

and verify the result returned is what we expect. Then we can use that same expression in a WHERE clause, comparing it to a DATE column like this:

 WHERE datecol = DATE(NOW()) + INTERVAL -1 DAY

For a DATETIME or TIMESTAMP column, we can use >= and < inequality comparisons to specify a range

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -1 DAY
   AND datetimecol <  DATE(NOW()) + INTERVAL  0 DAY

For "last 7 days" we need to know if that mean from this point right now, back 7 days ... e.g. the last 7*24 hours , including the time component in the comparison, ...

 WHERE datetimecol >= NOW() + INTERVAL -7 DAY
   AND datetimecol <  NOW() + INTERVAL  0 DAY

the last seven complete days, not including today

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -7 DAY
   AND datetimecol <  DATE(NOW()) + INTERVAL  0 DAY

or past six complete days plus so far today ...

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -6 DAY
   AND datetimecol <  NOW()       + INTERVAL  0 DAY

I recommend testing the expressions on the right side in a SELECT statement, we can use a user-defined variable in place of NOW() for testing, not being tied to what NOW() returns so we can test borders, across week/month/year boundaries, and so on.

SET @clock = '2017-11-17 11:47:47' ;

SELECT DATE(@clock)
     , DATE(@clock) + INTERVAL -7 DAY 
     , @clock + INTERVAL -6 DAY 

Once we have expressions that return values that work for "start" and "end" for our particular use case, what we mean by "last 7 days", we can use those expressions in range comparisons in the WHERE clause.

(Some developers prefer to use the DATE_ADD and DATE_SUB functions in place of the + INTERVAL val DAY/HOUR/MINUTE/MONTH/YEAR syntax.

And MySQL provides some convenient functions for working with DATE, DATETIME and TIMESTAMP datatypes... DATE, LAST_DAY,

Some developers prefer to calculate the start and end in other code, and supply string literals in the SQL query, such that the query submitted to the database is

  WHERE datetimecol >= '2017-11-10 00:00'
    AND datetimecol <  '2017-11-17 00:00'

And that approach works too. (My preference would be to explicitly cast those string literals into DATETIME, either with CAST, CONVERT or just the + INTERVAL trick...

  WHERE datetimecol >= '2017-11-10 00:00' + INTERVAL 0 SECOND
    AND datetimecol <  '2017-11-17 00:00' + INTERVAL 0 SECOND

The above all assumes we are storing "dates" in appropriate DATE, DATETIME and/or TIMESTAMP datatypes, and not storing them as strings in variety of formats e.g. 'dd/mm/yyyy', m/d/yyyy, julian dates, or in sporadically non-canonical formats, or as a number of seconds since the beginning of the epoch, this answer would need to be much longer.

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

Well, this solution might sound very silly, but can save you in certain conditions.

A friend of mine just ran into accidentally committing very some huge files (four auto-generated files ranging between 3GB to 5GB each) and then made some additional code commits on top of that before realizing the problem that git push wasn't working any longer!

The files had been listed in .gitignore but after renaming the container folder, they got exposed and committed! And now there were a few more commits of the code on top of that, but push was running forever (trying to upload GB of data!) and finally would fail due to Github's file size limits.

The problem with interactive rebase or anything similar was that they would deal with poking around these huge files and would take forever to do anything. Nevertheless, after spending almost an hour in the CLI, we weren't sure if the files (and deltas) are actually removed from the history or simply not included in the current commits. The push wasn't working either and my friend was really stuck.

So, the solution I came up with was:

1. Rename current git folder to ~/Project-old.
2. Clone the git folder again from github (to ~/Project).
3. Checkout to the same branch.
4. Manually cp -r the files from ~/Project-old folder to ~/Project.
5. Make sure the massive files, that are not needed to be checked in are mved, and included in .gitignore properly.
6. Also make sure you don't overwrite .git folder in the recently-cloned ~/Project by the old one. That's where the logs of the problematic history lives!
7. Now review the changes. It should be the union of all the recent commits, excluding the problematic files.
8. Finally commit the changes, and it's good to be push'ed.

The biggest problem with this solution is, it deals with manual copying some files, and also it merges all the recent commits into one (obviously with a new commit-hash.) B

The big benefits are that, it is very clear in every step, it works great for huge files (as well as sensitive ones), and it doesn't leave any trace in history behind!

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

Try

let str ="554,20";_x000D_
let float = +str.replace(',','.');_x000D_
let int = str.split(',').map(x=>+x);_x000D_
_x000D_
console.log({float,int});

final means that the value cannot be changed after initialization, that's what makes it a constant. static means that instead of having space allocated for the field in each object, only one instance is created for the class.

So, static final means only one instance of the variable no matter how many objects are created and the value of that variable can never change.

Although probably not exactly what your looking for and you probably don't care at this point since the question was asked 5 years ago, one method is to use "forward".

Go to your inbox or wherever your messages are and select the 2+ messages you want to send than simply click forward... all messages get combined into 1.

You can use Future.delayed to run your code after some time. e.g.:

Future.delayed(const Duration(milliseconds: 500), () {

// Here you can write your code

  setState(() {
    // Here you can write your code for open new view
  });

});

In setState function, you can write a code which is related to app UI e.g. refresh screen data, change label text, etc.

I'm not sure what you are doing wrong here, when I build a form using form classes Symfony takes care of selecting the correct option in the list. Here's an example of one of my forms that works.

In the controller for the edit action:

$entity = $em->getRepository('FooBarBundle:CampaignEntity')->find($id);

if (!$entity) {
throw $this->createNotFoundException('Unable to find CampaignEntity entity.');
}


$editForm = $this->createForm(new CampaignEntityType(), $entity);
$deleteForm = $this->createDeleteForm($id);

return $this->render('FooBarBundle:CampaignEntity:edit.html.twig', array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));

The campaign entity type class (src: Foo\BarBundle\Form\CampaignEntityType.php):

namespace Foo\BarBundle\Form;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
use Doctrine\ORM\EntityRepository;

class CampaignEntityType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder
        ->add('store', 'entity', array('class'=>'FooBarBundle:Store', 'property'=>'name', 'em'=>'my_non_default_em','required'  => true, 'query_builder' => function(EntityRepository $er) {return $er->createQueryBuilder('s')->orderBy('s.name', 'ASC');}))
        ->add('reward');
    }
    public function getName()
    {
        return 'foo_barbundle_campaignentitytype';
    }
}

Using break-inside should work:

@media print {
  div {
    break-inside: avoid;
  }
}

It works on all major browsers:

• Chrome 50+
• Edge 12+
• Firefox 65+
• Opera 37+
• Safari 10+

Using page-break-inside: avoid; instead should work too, but has been exactly deprecated by break-inside: avoid.

Run the installer from command line with argument /CustomInstallPath InstallationDirectory

See more command-line parameters and other installation information.

Note: this won't change location of all files, but only of those which can be (by design) installed onto different location. Be warned that there is many shared components which will be installed into shared repositories on drive C: without any possibility to change their path (unless you do some hacking using mklink /j (directory junction, i.e."hard link for folder"), but it is questionable whether it is worth it, because any Visual Studio updates will break those hard links. This is confirmed by people who tried that, although on Visual Studio 2012.)

Update: per recent comment, uninstallation of Visual Studio might be required before the above applies. Uninstallation command is like this: vs_community_ENU.exe /uninstall /force

I found that this works and seems more readable:

switch($someString)
{
    { @("y", "yes") -contains $_ } { "You entered Yes." }
    default { "You entered No." }
}

The "-contains" operator performs a non-case sensitive search, so you don't need to use "ToLower()". If you do want it to be case sensitive, you can use "-ccontains" instead.

Here's an alternate

req.hostname

Read about it in the Express Docs.

Have you tried to access your page by typing "http://localhost:8012" (after restarting the apache)?

No one has mentioned the obvious:

var myCallback = function() { console.log("name or age changed"); };
$scope.$watch("name", myCallback);
$scope.$watch("age", myCallback);

This might mean a little less polling. If you watch both name + age (for this) and name (elsewhere) then I assume Angular will effectively look at name twice to see if it's dirty.

It's arguably more readable to use the callback by name instead of inlining it. Especially if you can give it a better name than in my example.

And you can watch the values in different ways if you need to:

$scope.$watch("buyers", myCallback, true);
$scope.$watchCollection("sellers", myCallback);

$watchGroup is nice if you can use it, but as far as I can tell, it doesn't let you watch the group members as a collection or with object equality.

If you need the old and new values of both expressions inside one and the same callback function call, then perhaps some of the other proposed solutions are more convenient.

in 1.x there used to be things DataTables couldn't do which DataSets could (don't remember exactly what). All that was changed in 2.x. My guess is that's why a lot of examples still use DataSets. DataTables should be quicker as they are more lightweight. If you're only pulling a single resultset, its your best choice between the two.

It is possible using ConfigTransform build target available as a Nuget package - https://www.nuget.org/packages/CodeAssassin.ConfigTransform/

All "web.*.config" transform files will be transformed and output as a series of "web.*.config.transformed" files in the build output directory regardless of the chosen build configuration.

The same applies to "app.*.config" transform files in non-web projects.

and then adding the following target to your *.csproj.

<Target Name="TransformActiveConfiguration" Condition="Exists('$(ProjectDir)/Web.$(Configuration).config')" BeforeTargets="Compile" >
    <TransformXml Source="$(ProjectDir)/Web.Config" Transform="$(ProjectDir)/Web.$(Configuration).config" Destination="$(TargetDir)/Web.config" />
</Target>

For more generic advice on debugging this kind of problem MDN have a good article TypeError: "x" is not a function:

It was attempted to call a value like a function, but the value is not actually a function. Some code expects you to provide a function, but that didn't happen.

Maybe there is a typo in the function name? Maybe the object you are calling the method on does not have this function? For example, JavaScript objects have no map function, but JavaScript Array object do.

Basically the object (all functions in js are also objects) does not exist where you think it does. This could be for numerous reasons including(not an extensive list):

• Missing script library
• Typo
• The function is within a scope that you currently do not have access to, e.g.:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//the global scope can't access y because it is closed over in x and not exposed_x000D_
//y is not a function err triggered_x000D_
x.y();

• Your object/function does not have the function your calling:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//z is not a function error (as above) triggered_x000D_
x.z();

You are on the right track. Since you said you can't modify the global settings, then the next best thing is to apply the JsonConverter attribute on an as-needed basis, as you suggested. It turns out Json.Net already has a built-in IsoDateTimeConverter that lets you specify the date format. Unfortunately, you can't set the format via the JsonConverter attribute, since the attribute's sole argument is a type. However, there is a simple solution: subclass the IsoDateTimeConverter, then specify the date format in the constructor of the subclass. Apply the JsonConverter attribute where needed, specifying your custom converter, and you're ready to go. Here is the entirety of the code needed:

class CustomDateTimeConverter : IsoDateTimeConverter
{
    public CustomDateTimeConverter()
    {
        base.DateTimeFormat = "yyyy-MM-dd";
    }
}

If you don't mind having the time in there also, you don't even need to subclass the IsoDateTimeConverter. Its default date format is yyyy'-'MM'-'dd'T'HH':'mm':'ss.FFFFFFFK (as seen in the source code).

I will suggest creating a setup project for the reasons while deploying this seems the best convinience , no headaches of copying files manually. Follow the Windows service setup creation tutorial and you know how to create it. And this instance is for vb.net but it is the same for any type.

This answer was made pre-JPA2 implementations, if you're using JPA2, see the ElementCollection answer above:

Lists of objects inside a model object are generally considered "OneToMany" relationships with another object. However, a String is not (by itself) an allowable client of a One-to-Many relationship, as it doesn't have an ID.

So, you should convert your list of Strings to a list of Argument-class JPA objects containing an ID and a String. You could potentially use the String as the ID, which would save a little space in your table both from removing the ID field and by consolidating rows where the Strings are equal, but you would lose the ability to order the arguments back into their original order (as you didn't store any ordering information).

Alternatively, you could convert your list to @Transient and add another field (argStorage) to your class that is either a VARCHAR() or a CLOB. You'll then need to add 3 functions: 2 of them are the same and should convert your list of Strings into a single String (in argStorage) delimited in a fashion that you can easily separate them. Annotate these two functions (that each do the same thing) with @PrePersist and @PreUpdate. Finally, add the third function that splits the argStorage into the list of Strings again and annotate it @PostLoad. This will keep your CLOB updated with the strings whenever you go to store the Command, and keep the argStorage field updated before you store it to the DB.

I still suggest doing the first case. It's good practice for real relationships later.
