Great response by Jim Morris, I stumbled upon this and it took me a while to figure. Here is some simple code that shows that after submitting a "request" for a unique_lock boost (version 1.54) blocks all shared_lock requests. This is very interesting as it seems to me that choosing between unique_lock and upgradeable_lock allows if we want write priority or no priority.

Also (1) in Jim Morris's post seems to contradict this: Boost shared_lock. Read preferred?

#include <iostream>
#include <boost/thread.hpp>

using namespace std;

typedef boost::shared_mutex Lock;
typedef boost::unique_lock< Lock > UniqueLock;
typedef boost::shared_lock< Lock > SharedLock;

Lock tempLock;

void main2() {
    cout << "10" << endl;
    UniqueLock lock2(tempLock); // (2) queue for a unique lock
    cout << "11" << endl;
    boost::this_thread::sleep(boost::posix_time::seconds(1));
    lock2.unlock();
}

void main() {
    cout << "1" << endl;
    SharedLock lock1(tempLock); // (1) aquire a shared lock
    cout << "2" << endl;
    boost::thread tempThread(main2);
    cout << "3" << endl;
    boost::this_thread::sleep(boost::posix_time::seconds(3));
    cout << "4" << endl;
    SharedLock lock3(tempLock); // (3) try getting antoher shared lock, deadlock here
    cout << "5" << endl;
    lock1.unlock();
    lock3.unlock();
}

Why don't you do:

String number = String.valueOf(input);
char[] digits = number.toCharArray();

this code will work ,

.navbar .navbar-nav > li .navbar-item ,
.navbar .navbar-brand{
                       color: red;
                      }

paste in your css and run if you have a element below

<li>@Html.ActionLink("Login", "Login", "Home", new { area = "" },
 new { @class = "navbar-item" })</li>

<li> <button class="navbar-item">hi</button></li>

Also try System.currentTimeMillis()

Check if the session is empty or not in C# MVC Version Lower than 5.

if (!string.IsNullOrEmpty(Session["emp_num"] as string))
{
    //cast it and use it
    //business logic
}

Check if the session is empty or not in C# MVC Version Above 5.

if(Session["emp_num"] != null)
{
    //cast it and use it
    //business logic
}

If a function does not return anything, e.g.:

def test():
    pass

it has an implicit return value of None.

Thus, as your pick* methods do not return anything, e.g.:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")

the lines that call them, e.g.:

word = pickEasy()

set word to None, so wordInput in getInput is None. This means that:

if guess in wordInput:

is the equivalent of:

if guess in None:

and None is an instance of NoneType which does not provide iterator/iteration functionality, so you get that type error.

The fix is to add the return type:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

The 500 (internal server error) means something went wrong on the server's side. It could be several things, but I would start by verifying that the URL and parameters are correct. Also, make sure that whatever handles the request is expecting the request as a GET and not a POST.

One useful way to learn more about what's going on is to use a tool like Fiddler which will let you watch all HTTP requests and responses so you can see exactly what you're sending and the server is responding with.

If you don't have a compelling reason to write your own Ajax code, you would be far better off using a library that handles the Ajax interactions for you. jQuery is one option.

    try {
        InputStream connInputStream = connection.getInputStream();
    } catch (IOException e) {
        e.printStackTrace();
    }

    int size = connInputStream.available();

int available () Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream. The next invocation might be the same thread or another thread. A single read or skip of this many bytes will not block, but may read or skip fewer bytes.

Six Dependency scopes:

• compile: default scope, classpath is available for both src/main and src/test
• test: classpath is available for src/test
• provided: like complie but provided by JDK or a container at runtime
• runtime: not required for compilation only require at runtime
• system: provided locally provide classpath
• import: can only import other POMs into the <dependencyManagement/>, only available in Maven 2.0.9 or later (like java import )

there is a good library to use its called djagno-nomad, although not directly related to the question asked, thought of sharing this,

scenario: most of the time when switching to project, we feel like it should revert our changes that we did on this current branch, that's what exactly this library does, checkout below

https://pypi.org/project/django-nomad/

You can also get this error if you don't specify center or zoom in your map options.

The code below does just that. The below is a working example to log into a game. I made a similar file to log in into Yahoo and a kurzweilai.net forum.

Just copy the login form from any webpage's source code. Add value= "your user name" and value = "your password". Normally the -input- elements in the source code do not have the value attribute, and sometime, you will see something like that: value=""

Save the file as a html on a local machine double click it, or make a bat/cmd file to launch and close them as required.

    <!doctype html>
    <!-- saved from url=(0014)about:internet -->

    <html>
    <title>Ikariam Autologin</title>
    </head>
    <body>
    <form id="loginForm" name="loginForm" method="post"    action="http://s666.en.ikariam.com/index.php?action=loginAvatar&function=login">
    <select name="uni_url" id="logServer" class="validate[required]">
    <option  class=""  value="s666.en.ikariam.com" fbUrl=""  cookieName=""  >
            Test_en
    </option>
    </select>
    <input id="loginName" name="name" type="text" value="PlayersName" class="" />
    <input id="loginPassword" name="password" type="password" value="examplepassword" class="" />
    <input type="hidden" id="loginKid" name="kid" value=""/>
                        </form>
  <script>document.loginForm.submit();</script>       
  </body></html>

Note that -script- is just -script-. I found there is no need to specify that is is JavaScript. It works anyway. I also found out that a bare-bones version that contains just two input filds: userName and password also work. But I left a hidded input field etc. just in case. Yahoo mail has a lot of hidden fields. Some are to do with password encryption, and it counts login attempts.

Security warnings and other staff, like Mark of the Web to make it work smoothly in IE are explained here:

To count unique values in column, say hID of dataframe df, use:

len(df.hID.unique())

The best and easiest way to clear a JLIST is:

myJlist.setListData(new String[0]);

When using jQuery in asp.net, if you are using a master page and you are loading the jquery source file there, make sure you have the header contentplaceholder after all the jquery script references.

I had a problem where any pages that used that master page would return '$ is not defined' simply because the incorrect order was making the client side code run before the jquery object was created. So make sure you have:

<head runat="server">
    <script type="text/javascript" src="Scripts/jquery-VERSION#.js"></script>
    <asp:ContentPlaceHolder id="Header" runat="server"></asp:ContentPlaceHolder>
</head>

That way the code will run in order and you will be able to run jQuery code on the child pages.

Once you get the cursor you can do

Cursor.getCount()

Still an issue in Microsoft Office 2016 release, rather disturbing for those of us working with gene names such as MARC1, MARCH1, SEPT1 etc. The solution I've found to be the most practical after generating a ".csv" file in R, that will then be opened/shared with Excel users:

1. Open the CSV file as text (notepad)
2. Copy it (ctrl+a, ctrl+c).
3. Paste it in a new excel sheet -it will all paste in one column as long text strings.
4. Choose/select this column.
5. Go to Data- "Text to columns...", on the window opened choose "delimited" (next). Check that "comma" is marked (marking it will already show the separation of the data to columns below) (next), in this window you can choose the column you want and mark it as text (instead of general) (Finish).

import json
some_list = ['one', 'two', 'three', 'four']

    "three",
    "four"
]

Try copying the src and web folder in different folder location and create New project with existing sources in Netbeans. This should work. Or remove the nbproject folder as well before importing.

Suggest calling 'Now' only once in the function to guard against the minute, or even the day, changing during the execution of the function.

Thus:

Function timeStamp()
    Dim t 
    t = Now
    timeStamp = Year(t) & "-" & _
    Right("0" & Month(t),2)  & "-" & _
    Right("0" & Day(t),2)  & "_" & _  
    Right("0" & Hour(t),2) & _
    Right("0" & Minute(t),2) '    '& _    Right("0" & Second(t),2) 
End Function

Not very hard, just use m.get(i) to get the value from the list.

public double incassoMargherita()
{
    double sum = 0;
    for(int i = 0; i < m.size(); i++)
    {
        sum += m.get(i);
    }
    return sum;
}

In addition to kiran's post, there's the update helper (formerly a react addon). This can be installed with npm using npm install immutability-helper

import update from 'immutability-helper';

var abc = update(this.state.abc, {
   xyz: {$set: 'foo'}
});

this.setState({abc: abc});

This creates a new object with the updated value, and other properties stay the same. This is more useful when you need to do things like push onto an array, and set some other value at the same time. Some people use it everywhere because it provides immutability.

If you do this, you can have the following to make up for the performance of

shouldComponentUpdate: function(nextProps, nextState){
   return this.state.abc !== nextState.abc; 
   // and compare any props that might cause an update
}

There is not an equivalent statement for export in Windows Command Prompt. In Windows the environment is copied so when you exit from the session (from a called command prompt or from an executable that set a variable) the variable in Windows get lost. You can set it in user registry or in machine registry via setx but you won't see it if you not start a new command prompt.

To round up an integer division you can use

import static java.lang.Math.abs;

public static long roundUp(long num, long divisor) {
    int sign = (num > 0 ? 1 : -1) * (divisor > 0 ? 1 : -1);
    return sign * (abs(num) + abs(divisor) - 1) / abs(divisor);
}

or if both numbers are positive

public static long roundUp(long num, long divisor) {
    return (num + divisor - 1) / divisor;
}

In cryptography there are two types of algorithms used:

Symmetric algorithms

A single key is used to encrypt data. When encrypted with the key, the data can be decrypted using the same key. If, for example, Mary encrypts a message using the key "my-secret" and sends it to John, he will be able to decrypt the message correctly with the same key "my-secret".

Asymmetric algorithms

Two keys are used to encrypt and decrypt messages. While one key(public) is used to encrypt the message, the other key(private) can only be used to decrypt it. So, John can generate both public and private keys, then send only the public key to Mary to encrypt her message. The message can only be decrypted using the private key.

HS256 and RS256 Scenario

These algorithms are NOT used to encrypt/decryt data. Rather they are used to verify the origin or the authenticity of the data. When Mary needs to send an open message to Jhon and he needs to verify that the message is surely from Mary, HS256 or RS256 can be used.

HS256 can create a signature for a given sample of data using a single key. When the message is transmitted along with the signature, the receiving party can use the same key to verify that the signature matches the message.

RS256 uses pair of keys to do the same. A signature can only be generated using the private key. And the public key has to be used to verify the signature. In this scenario, even if Jack finds the public key, he cannot create a spoof message with a signature to impersonate Mary.

Thats an if/else statement equilavent to

if(row % 2 == 1){
  System.out.print("<");
}else{
  System.out.print("\r>");
}

I wrote a simple library for manipulating the JavaScript date object. You can try this:

var dateString = timeSolver.getString(new Date(), "YYYY/MM/DD HH:MM:SS.SSS")

Library here: https://github.com/sean1093/timeSolver

It is indeed based on versionCode and not on versionName. However, I noticed that changing the versionCode in AndroidManifest.xml wasn't enough with Android Studio - Gradle build system. I needed to change it in the build.gradle.

I'm not sure if you want to find duplicate files or just compare two single files. If the latter, the above approach (filecmp) is better, if the former, the following approach is better.

There are lots of duplicate files detection questions here. Assuming they are not very small and that performance is important, you can

• Compare file sizes first, discarding all which doesn't match
• If file sizes match, compare using the biggest hash you can handle, hashing chunks of files to avoid reading the whole big file

Here's is an answer with Python implementations (I prefer the one by nosklo, BTW)

You can set the SelectedValue to the value you want to select. If you already have selected item then you should clear the selection otherwise you would get "Cannot have multiple items selected in a DropDownList" error.

dropdownlist.ClearSelection();
dropdownlist.SelectedValue = value;

You can also use ListItemCollection.FindByText or ListItemCollection.FindByValue

dropdownlist.ClearSelection();  
dropdownlist.Items.FindByValue(value).Selected = true;

Use the FindByValue method to search the collection for a ListItem with a Value property that contains value specified by the value parameter. This method performs a case-sensitive and culture-insensitive comparison. This method does not do partial searches or wildcard searches. If an item is not found in the collection using this criteria, null is returned, MSDN.

If you expect that you may be looking for text/value that wont be present in DropDownList ListItem collection then you must check if you get the ListItem object or null from FindByText or FindByValue before you access Selected property. If you try to access Selected when null is returned then you will get NullReferenceException.

ListItem listItem = dropdownlist.Items.FindByValue(value);

if(listItem != null) 
{
   dropdownlist.ClearSelection();
   listItem.Selected = true;
}

If using jruby, here is a code snippet to return an array of all tables in a db.

require "rubygems"
require "jdbc/mysql"
Jdbc::MySQL.load_driver
require "java"

def get_database_tables(connection, db_name)
  md = connection.get_meta_data
  rs = md.get_tables(db_name, nil, '%',["TABLE"])

  tables = []
  count = 0
  while rs.next
    tables << rs.get_string(3)
  end #while
  return tables
end

This answer, but with storyboard support.

class SwipeNavigationController: UINavigationController {

    override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)

        self.setup()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

class Student(object):
    name = ""
    age = 0
    major = ""

    # The class "constructor" - It's actually an initializer 
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

def make_student(name, age, major):
    student = Student(name, age, major)
    return student

Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:

class Student(object):
    name = ""
    age = 0
    major = ""

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    # Note: I didn't need to create a variable in the class definition before doing this.
    student.gpa = float(4.0)
    return student

I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.

To just get the info of a CURL request do this:

$response = curl_exec($ch);

$info = curl_getinfo($ch);
var_dump($info);

I use the @Adi-lester answer and add some methods.

Method to verify if Session is Alive

public static void SessionIsAlive(HttpSessionStateBase Session)
{
    if (Session.Contents.Count == 0)
    {
        Response.Redirect("Timeout.html"); 
    }
    else
    {
        InitializeControls();
    }
}

Create session var in Page Load

protected void Page_Load(object sender, EventArgs e)
{
    Session["user_id"] = 1;
}

Create SaveData method (but you can use it in all methods)

protected void SaveData()
{
    // Verify if Session is Alive
    SessionIsAlive(Session);

    //Save Data Process
    // bla
    // bla
    // bla
}

I imagine the author just was looking for a way to get the first element of an array after getting it from some function (mysql_fetch_row, for example) without generating a STRICT "Only variables should be passed by reference".

If it so, almost all the ways described here will get this message... and some of them uses a lot of additional memory duplicating an array (or some part of it). An easy way to avoid it is just assigning the value inline before calling any of those functions:

$first_item_of_array = current($tmp_arr = mysql_fetch_row(...));
// or
$first_item_of_array = reset($tmp_arr = func_get_my_huge_array());

This way you don't get the STRICT message on screen, nor in logs, and you don't create any additional arrays. It works with both indexed AND associative arrays.

You can try this in an Activity:

getResources().getString(R.string.your string name);

In other situations like fragments,... use

getContext().getResources().getString(R.string.your string name);

You can use the ROBOCOPY command. It is very simple and can also be used to delete empty folders inside large hierarchy.

ROBOCOPY folder1 folder1 /S /MOVE

Here both source and destination are folder1, as you only need to delete empty folders, instead of moving other(required) files to different folder. /S option is to skip copying(moving - in the above case) empty folders. It is also faster as the files are moved inside the same drive.

There are multiple php config files, but THIS is the one you need to edit:

/etc/php(version)?/fpm/pool.d/www.conf

uncomment the line that says:

catch_workers_output

That will allow PHPs stderr to go to php-fpm's error log instead of /dev/null.

        if ( ! $_product->is_visible() ) {
                echo $_product->get_title();
        } else {
                echo $_product->get_title();
        }


     }

I was successful using tidy command line utility. On linux I installed it quickly with apt-get install tidy. Then the command:

tidy -q -asxml --numeric-entities yes source.html >file.xml

gave an xml file, which I was able to process with xslt processor. However I needed to set up xhtml1 dtds correctly.

This is their homepage: html-tidy.org (and the legacy one: HTML Tidy)

This one works for me (at least in Chrome and Firefox):

<input type="file" accept="image/*" title="&nbsp;"/>

You are most likely seeing the unexpected behavior because your text file was created on Windows, so the end of line sequence is \r\n. You can use dos2unix to convert it to a UNIX style text file before running sed or use

sed -r "/^\r?$/d"

to remove blank lines whether or not the carriage return is there.

If you are going to be programming an application to do all of this, the process will be something like this:

1. Convert image from RGB to HSV
2. adjust H value
3. Convert image back to RGB
4. Save image

document.getElementById('value').addEventListener('keydown', function(e) {
    var key   = e.keyCode ? e.keyCode : e.which;

/*lenght of value to use with index to know how many numbers after.*/

    var len = $('#value').val().length;
    var index = $('#value').val().indexOf('.');
    if (!( [8, 9, 13, 27, 46, 110, 190].indexOf(key) !== -1 ||
                    (key == 65 && ( e.ctrlKey || e.metaKey  ) ) ||
                    (key >= 35 && key <= 40) ||
                    (key >= 48 && key <= 57 && !(e.shiftKey || e.altKey)) ||
                    (key >= 96 && key <= 105)
            )){
        e.preventDefault();
    }

/*if theres a . count how many and if reachs 2 digits after . it blocks*/ 

    if (index > 0) {
        var CharAfterdot = (len + 1) - index;
        if (CharAfterdot > 3) {

/*permits the backsapce to remove :D could be improved*/

            if (!(key == 8))
            {
                e.preventDefault();
            }

/*blocks if you try to add a new . */

        }else if ( key == 110) {
            e.preventDefault();
        }

/*if you try to add a . and theres no digit yet it adds a 0.*/

    } else if( key == 110&& len==0){
        e.preventDefault();
        $('#value').val('0.');
    }
});

Use position:fixed, as previously stated, IE6 doesn't recognize position:fixed, but with some css magic you can get IE6 to behave:

html, body {
    height: 100%;
    overflow:auto;
}
body #fixedElement {
    position:fixed !important;
    position: absolute; /*ie6 */
    bottom: 0;
}

The !important flag makes it so you don't have to use a conditional comment for IE. This will have #fixedElement use position:fixed in all browsers but IE, and in IE, position:absolute will take effect with bottom:0. This will simulate position:fixed for IE6

I was having the same issue. I tried with the compatibility option, but in Windows 10 it doesn't show the compatibility option. The following steps solved the problem for me:

1. I made sure the account with which the task was running had the full access privileges on the file to be executed. (Executed the task and was still not running)
2. I man taskschd.msc as administrator
3. I added the account to run the task (whether was it logged or not)
4. I executed the task and now IT WORKED!

So somehow setting up the task in taskschd.msc as a regular user wasn't working, even though my account is an admin one.

Hope this helps anyone having the same issue

I dont know why but it worked for me. If you have comments like

//Comment

Then it gives this error. To fix this do

/*Comment*/

Doesn't make sense but it worked for me.

also you can reimplement protected member QWidget::closeEvent()

void YourWidgetWithXButton::closeEvent(QCloseEvent *event)
{
    // do what you need here
    // then call parent's procedure
    QWidget::closeEvent(event);
}

Using a single Awk:

... | awk -F '[/:]' '{print $5}'

That is, using as field separator either / or :, the username is always in field 5.

To store it in a variable:

username=$(... | awk -F '[/:]' '{print $5}')

A more flexible implementation with sed that doesn't require username to be field 5:

... | sed -e s/:.*// -e s?.*/??

That is, delete everything from : and beyond, and then delete everything up until the last /. sed is probably faster too than awk, so this alternative is definitely better.

It is used in the new short hand for/loop

final List<String> list = new ArrayList<String>();
for (final String s : list)
{
   System.out.println(s);
}

and the ternary operator

list.isEmpty() ? true : false;

It is very bad style to define external interfaces in .c files. .

You should do this

a.h

    extern void doSomething (int    sig);

a.c

    void doSomething (int    sig)
    {
       ... do stuff 
    }

b.c

#include "a.h"
.....
signal(SIGNAL, doSomething);

I know the question is 9 years old, but maybe for someone it will be interested furthermore. According to the question, to change the buffer size only, it can be used Powershell. The shortest command with Powershell is:

powershell -command "&{(get-host).ui.rawui.buffersize=@{width=155;height=999};}"

Replace the values of width and height with your wanted values.

But supposedly the reason of your question is to modify the size of command line window without reducing of the buffer size. For that you can use the following command:

start /b powershell -command "&{$w=(get-host).ui.rawui;$w.buffersize=@{width=177;height=999};$w.windowsize=@{width=155;height=55};}"

There you can modify the size of buffer and window independly. To avoid an error message, consider that the values of buffersize must be bigger or equal to the values of windowsize.

Additional implemented is the start /b command. The Powershell command sometimes takes a few seconds to execute. With this additional command, Powershell runs parallel and does not significantly delay the processing of the following commands.

Sometimes I had the same issues when I forget to add Lombok annotation processor dependency to the maven configuration

If you're getting something like getElementById call returns null, it's probably because the function is running, but the ID hasn't had time to load in the DOM.

Try using Will's answer (towards the top) with a delay. Example:

angular.module('MyApp', [])

.controller('MyCtrl', [function() {
    $scope.sleep = (time) => {
        return new Promise((resolve) => setTimeout(resolve, time));
    };
    angular.element(document).ready(function () {
        $scope.sleep(500).then(() => {        
            //code to run here after the delay
        });
    });
}]);

$('#form').keydown(function(e){
    if (e.keyCode === 13) { // If Enter key pressed
        $(this).trigger('submit');
    }
});

I remember when "ANSI" text referred to the pseudo VT-100 escape codes usable in DOS through the ANSI.SYS driver to alter the flow of streaming text.... Probably not what you are referring to but if it is see http://en.wikipedia.org/wiki/ANSI_escape_code

I got this problem when I try to clone a git repo in Linux machine.

the following URL is working for me in windows

http://[email protected]/scm/project/swamy-main.git

whereas the following URL works in Linux machine and it has https in URL

Of the three solutions only Option 1 is polymorphic.

Fields by themselves cannot be overridden. Which is exactly why Option 2 returns the new keyword warning.

The solution to the warning is not to append the “new” keyword, but to implement Option 1.

If you need your field to be polymorphic you need to wrap it in a Property.

Option 3 is OK if you don’t need polymorphic behavior. You should remember though, that when at runtime the property MyInt is accessed, the derived class has no control on the value returned. The base class by itself is capable of returning this value.

This is how a truly polymorphic implementation of your property might look, allowing the derived classes to be in control.

abstract class Parent
{
    abstract public int MyInt { get; }
}

class Father : Parent
{
    public override int MyInt
    {
        get { /* Apply formula "X" and return a value */ }
    }
}

class Mother : Parent
{
    public override int MyInt
    {
        get { /* Apply formula "Y" and return a value */ }
    }
}

You can solve the problem changing the compileSdkVersion in the Grandle.build file from 18 to wtever SDK is installed ..... BUTTTTT

1. If you are trying to goin back in SDK versions like 18 to 17 ,You can not use the feature available in 18 or 18+

2. If you are migrating your project (Eclipse to Android Studio ) Then off course you Don't have build.gradle file in your Existed Eclipse project

So, the only solution is to ensure the SDK version installed or not, you are targeting to , If not then install.

Error:Cause: failed to find target with hash string 'android-19' in: C:\Users\setia\AppData\Local\Android\sdk

What about an onclick function:

    <form id="form">
    <input type="text" name="firstInput">
    <button type="button" name="namebutton" 
           onClick="$('#gif').css('visibility', 'visible');
                    $('#form').submit();">
    </form>

Of course you can put this in a function and then trigger it with an onClick

It seems like sometime during the second half of 2018 many php packages such as php-mysql and phpmyadmin were removed or changed. I faced that same problem too. So you'll have to download it from another source or find out the new packages

Also, you can utilize crash dumps to debug your software. The customer sends it to you and then you can use it to identify the exact version of your source - and Visual Studio will even pull the right set of debugging symbols (and source if you're set up correctly) using the crash dump. See Microsoft's documentation on Symbol Stores.

So, I hear this works:

Data$X1<-as.character(Data$X1)
Data$GEOID<-as.character(Data$BLKIDFP00)
Data<-within(Data,X1<-ifelse(is.na(Data$X1),GEOID,Data$X2)) 

But I admit I have only intermittent luck with it.

Try out cat and sprintf in your for loop.

eg.

cat(sprintf("\"%f\" \"%f\"\n", df$r, df$interest))

See here

With the constructor:

// create a vector with 20 integer elements
std::vector<int> arr(20);

for(int x = 0; x < 20; ++x)
   arr[x] = x;

Enabling error displaying from PHP code doesn't work out for me. In my case, using NGINX and PHP-FMP, I track the log file using grep. For instance, I know the file name mycode.php causes the error 500, but don't know which line. From the console, I use this:

/var/log/php-fpm# cat www-error.log | grep mycode.php

And I have the output:

[04-Apr-2016 06:58:27] PHP Parse error:  syntax error, unexpected ';' in /var/www/html/system/mycode.php on line 1458

This helps me find the line where I have the typo.

When you change an ASP.NET website's configuration file, it restarts the application to reflect the changes...

When you do an IIS reset, that restarts all applications running on that IIS instance.

Essentially random access file wraps input and output streams in order to manage the random access. You don't open and close a file, you open and close streams to a file.

Ran into this exact problem.

What I ended up doing:

# starting with date string
sdt = "20190901"
std_format = '%Y%m%d'

# create naive datetime object
from datetime import datetime
dt = datetime.strptime(sdt, sdt_format)

# extract the relevant date time items
dt_formatters = ['%Y','%m','%d']
dt_vals = tuple(map(lambda formatter: int(datetime.strftime(dt,formatter)), dt_formatters))

# set timezone
import pendulum
tz = pendulum.timezone('utc')

dt_tz = datetime(*dt_vals,tzinfo=tz)

What's wrong with

func (e *Easy)SetStringOption(option Option, param string)
func (e *Easy)SetLongOption(option Option, param long)

and so on?

UPDATE:

I came up with this solution when I was pretty new to web design. Now that I am older and wiser, the answer Liam gave seems to be a better option. See the next top answer; it is a more productive solution.

I worked on a project recently and this example worked perfectly. I am giving you the link below.

First you have to add jQuery mobile:

http://jquerymobile.com/

This adds the touch functionality, and then you just have to make events such as swipe:

<script>
$(document).ready(function() {
   $("#myCarousel").swiperight(function() {
      $(this).carousel('prev');
    });
   $("#myCarousel").swipeleft(function() {
      $(this).carousel('next');
   });
});
</script>

The link is below, where you can find the tutorial I used:

http://lazcreative.com/blog/how-to/how-to-adding-swipe-support-to-bootstraps-carousel/

Here is a simple solution:

var val = $('#mylist option:selected').text()

Check this example: JsFiddle.

Note that if strings has spaces then quotation marks are needed at definition and must be chopped while concatenating:

rem The retail files set
set FILES_SET="(*.exe *.dll"

rem The debug extras files set
set DEBUG_EXTRA=" *.pdb"

rem Build the DEBUG set without any
set FILES_SET=%FILES_SET:~1,-1%%DEBUG_EXTRA:~1,-1%

rem Append the closing bracket
set FILES_SET=%FILES_SET%)

echo %FILES_SET%

Cheers...

To subtract timevals:

gettimeofday(&t0, 0);
/* ... */
gettimeofday(&t1, 0);
long elapsed = (t1.tv_sec-t0.tv_sec)*1000000 + t1.tv_usec-t0.tv_usec;

This is assuming you'll be working with intervals shorter than ~2000 seconds, at which point the arithmetic may overflow depending on the types used. If you need to work with longer intervals just change the last line to:

long long elapsed = (t1.tv_sec-t0.tv_sec)*1000000LL + t1.tv_usec-t0.tv_usec;

Using all built-ins..

tuple(map(sum, zip(a, b)))

In JavaScript using Associative array:
this:

function getItemPricing(customer, item) {
    switch (customer.type) {
        // VIPs are awesome. Give them 50% off.
        case 'VIP':
            return item.price * item.quantity * 0.50;

            // Preferred customers are no VIPs, but they still get 25% off.
        case 'Preferred':
            return item.price * item.quantity * 0.75;

            // No discount for other customers.
        case 'Regular':
        case
        default:
            return item.price * item.quantity;
    }
}

becomes this:

function getItemPricing(customer, item) {
var pricing = {
    'VIP': function(item) {
        return item.price * item.quantity * 0.50;
    },
    'Preferred': function(item) {
        if (item.price <= 100.0)
            return item.price * item.quantity * 0.75;

        // Else
        return item.price * item.quantity;
    },
    'Regular': function(item) {
        return item.price * item.quantity;
    }
};

    if (pricing[customer.type])
        return pricing[customer.type](item);
    else
        return pricing.Regular(item);
}

This is what I used to use a csv file into an array. Couldn't get the above answers to work, but this worked for me.

$(document).ready(function() {
   "use strict";
    $.ajax({
        type: "GET",
        url: "../files/icd10List.csv",
        dataType: "text",
        success: function(data) {processData(data);}
     });
});

function processData(icd10Codes) {
    "use strict";
    var input = $.csv.toArrays(icd10Codes);
    $("#test").append(input);
}

Used the jQuery-CSV Plug-in linked above.

May I suggest using the fish bone operator?

for (auto x = std::end(a); x != std::begin(a); )
{
    std::cout <<*--x<< ' ';
}

(Can you spot it?)

What about something like this?

var arr = [];

$('[id^=event]', response).each(function(){
    arr.push($(this).html());
});

The [attr^=selector] selector matches elements on which the attr attribute starts with the given string, that way you don't care about the numbers after "event".

Here are the steps I used to manually install python3 for anyone else who wants to do it as it's not super straight forward. EDIT: It's almost certainly easier to use the yum package manager (see other answers).

Note, you'll probably want to do sudo yum groupinstall 'Development Tools' before doing this otherwise pip won't install.

wget https://www.python.org/ftp/python/3.4.2/Python-3.4.2.tgz
tar zxvf Python-3.4.2.tgz
cd Python-3.4.2
sudo yum install gcc
./configure --prefix=/opt/python3
make
sudo yum install openssl-devel
sudo make install
sudo ln -s /opt/python3/bin/python3 /usr/bin/python3
python3 (should start the interpreter if it's worked (quit() to exit)

An alternative way to do this could be select distinct PersonId and group join with persons:

var result = 
    from id in persons.Select(x => x.PersonId).Distinct()
    join p2 in persons on id equals p2.PersonId into gr // apply group join here
    select new 
    {
        PersonId = id,
        Cars = gr.Select(x => x.Car).ToList(),
    };

Or the same with fluent API syntax:

var result = persons.Select(x => x.PersonId).Distinct()
    .GroupJoin(persons, id => id, p => p.PersonId, (id, gr) => new
    {
        PersonId = id,
        Cars = gr.Select(x => x.Car).ToList(),
    });

GroupJoin produces a list of entries in the first list ( list of PersonId in our case), each with a group of joined entries in the second list (list of persons).

For those on Mac OS Mountain Lion, I followed the anwser of zeantsoi, but it doesn't work.

I finally ended up with the solution of this post: http://appelfreelance.com/2010/06/libjpeg-pil-snow-leopard-python2-6-_jpeg_resync_to_restart/

Now, I'm happily running my script for jpeg !

It took me a while to figure this out too. url_for in Flask looks for endpoints that you specified in the routes.py script.

So if you have a decorator in your routes.py file like @blah.route('/folder.subfolder') then Flask will recognize the command {{ url_for('folder.subfolder') , filename = "some_image.jpg" }} . The 'folder.subfolder' argument sends it to a Flask endpoint it recognizes.

However let us say that you stored your image file, some_image.jpg, in your subfolder, BUT did not specify this subfolder as a route endpoint in your flask routes.py, your route decorator looks like @blah.routes('/folder'). You then have to ask for your image file this way: {{ url_for('folder'), filename = 'subfolder/some_image.jpg' }}

I.E. you tell Flask to go to the endpoint it knows, "folder", then direct it from there by putting the subdirectory path in the filename argument.

Most people already tried to answer your questions.
If you are still debugging, have you thought about using:

Double.TryParse(String, Double);

This will help you in determining what is wrong in each of the string first before you do the actual parsing.
If you have a culture-related problem, you might consider using:

Double.TryParse(String, NumberStyles, IFormatProvider, Double);

This http://msdn.microsoft.com/en-us/library/system.double.tryparse.aspx has a really good example on how to use them.

If you need a long, Int64.TryParse is also available: http://msdn.microsoft.com/en-us/library/system.int64.tryparse.aspx

Hope that helps.

There are no variables in Python

The key to understanding parameter passing is to stop thinking about "variables". There are names and objects in Python and together they appear like variables, but it is useful to always distinguish the three.

1. Python has names and objects.
2. Assignment binds a name to an object.
3. Passing an argument into a function also binds a name (the parameter name of the function) to an object.

That is all there is to it. Mutability is irrelevant to this question.

Example:

a = 1

This binds the name a to an object of type integer that holds the value 1.

b = x

This binds the name b to the same object that the name x is currently bound to. Afterward, the name b has nothing to do with the name x anymore.

See sections 3.1 and 4.2 in the Python 3 language reference.

How to read the example in the question

In the code shown in the question, the statement self.Change(self.variable) binds the name var (in the scope of function Change) to the object that holds the value 'Original' and the assignment var = 'Changed' (in the body of function Change) assigns that same name again: to some other object (that happens to hold a string as well but could have been something else entirely).

How to pass by reference

So if the thing you want to change is a mutable object, there is no problem, as everything is effectively passed by reference.

If it is an immutable object (e.g. a bool, number, string), the way to go is to wrap it in a mutable object.
The quick-and-dirty solution for this is a one-element list (instead of self.variable, pass [self.variable] and in the function modify var[0]).
The more pythonic approach would be to introduce a trivial, one-attribute class. The function receives an instance of the class and manipulates the attribute.

Just to clarify - at least from what we found on our side! It is an issue with the setup of the randomizer for Linux in the JDK distribution - and we found it in Java6, not sure about Java7. The syntax for linux for the randomizer is file:///dev/urandom, but the entry in the file is (probably left/copied from Windows) as file:/dev/urandom. So then Java probably falls back on the default, which happens to be /dev/random. And which doesn't work on a headless machine!!!

define('SECONDS_PER_DAY', 86400);
$days_ago = date('Y-m-d', time() - 5 * SECONDS_PER_DAY);

Other than that, you can use strtotime for any date:

$days_ago = date('Y-m-d', strtotime('January 18, 2034') - 5 * SECONDS_PER_DAY);

Or, as you used, mktime:

$days_ago = date('Y-m-d', mktime(0, 0, 0, 12, 2, 2008) - 5 * SECONDS_PER_DAY);

Well, you get it. The key is to remove enough seconds from the timestamp.

In Addition to @thefourtheye answer, using predicate instead of traditional anonymous functions:

  _.remove(obj.subTopics, (currentObject) => {
        return currentObject.subTopicId === stToDelete;
    });

OR

obj.subTopics = _.filter(obj.subTopics, (currentObject) => {
    return currentObject.subTopicId !== stToDelete;
});

Do not depend on ADB shell, just treat it (the adb logcat) a normal linux output and then pip it:

$ adb shell logcat | grep YouTag
# just like: 
$ ps -ef | grep your_proc 

I wanted a one-liner that didn't download any files; here is an example of piping the cookie output into the next request. I only tested the following on Gentoo, but it should work in most *nix environments:

wget -q -O /dev/null --save-cookies /dev/stdout --post-data 'u=user&p=pass' 'http://example.com/login' | wget -q -O - --load-cookies /dev/stdin 'http://example.com/private/page'

(This is one line, though it likely wraps on your browser)

If you want the output saved to a file, change -O - to -O /some/file/name.ext

You are mixing the deprecated mysql extension with mysqli.

Try something like:

$sql = mysqli_query($success, "SELECT * FROM login WHERE username = '".$_POST['username']."' and password = '".md5($_POST['password'])."'");
$row = mysqli_num_rows($sql);

<a href="#" (click)="onGoToPage2()">Go to page 2</a>

I wrote a very simple class for exporting to "Excel XML" aka SpreadsheetML. It's not quite as convenient for the end user as XSLX (depending on file extension and Excel version, they may get a warning message), but it's a lot easier to work with than XLS or XLSX.

Found an XML transform stylesheet here (wayback machine link, site itself is in german)

The stylesheet added here could be helpful:

Perhaps you want to remove the quotes inside the xsl:if tags so it doesn't put your values into quotes, depending on where you want to use the CSV file.

You need to use either PHP's ImageMagick or GD functions to work with images.

With GD, for example, it's as simple as...

function resize_image($file, $w, $h, $crop=FALSE) {
    list($width, $height) = getimagesize($file);
    $r = $width / $height;
    if ($crop) {
        if ($width > $height) {
            $width = ceil($width-($width*abs($r-$w/$h)));
        } else {
            $height = ceil($height-($height*abs($r-$w/$h)));
        }
        $newwidth = $w;
        $newheight = $h;
    } else {
        if ($w/$h > $r) {
            $newwidth = $h*$r;
            $newheight = $h;
        } else {
            $newheight = $w/$r;
            $newwidth = $w;
        }
    }
    $src = imagecreatefromjpeg($file);
    $dst = imagecreatetruecolor($newwidth, $newheight);
    imagecopyresampled($dst, $src, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

    return $dst;
}

And you could call this function, like so...

$img = resize_image(‘/path/to/some/image.jpg’, 200, 200);

From personal experience, GD's image resampling does dramatically reduce file size too, especially when resampling raw digital camera images.

This code would help:

int [] a={1,2,3,4,5,6,7};
for(int i=a.length-1;i>=0;i--)
  System.out.println(a[i]);

I had a lot of trouble with this too. Couldn't get it working using the case examples above, but this does the job for me:

Replace(rtrim(ltrim(ISNULL(Flat_no, '') + 
' ' + ISNULL(House_no, '') + 
' ' + ISNULL(Street, '') + 
' ' + ISNULL(Town, '') + 
' ' + ISNULL(City, ''))),'  ',' ')

Replace corrects the double spaces caused by concatenating single spaces with nothing between them. r/ltrim gets rid of any spaces at the ends.

There are many answers but Will some more observation it.

1. clip

Clip the overflowing text to fix its container.

You can give your objects their own toString methods in their prototypes.

This is the most complicated scenario I can imagine: I have a PDF file created with Ilustrator and modified with Acrobat to have AcroFields (AcroForm) that I'm going to fill with data with this Java code, the result of that PDF file with the data in the fields is modified adding a Document.

Actually in this case I'm dynamically generating a background that is added to a PDF that is also dynamically generated with a Document with an unknown amount of data or pages.

I'm using JBoss and this code is inside a JSP file (should work in any JSP webserver).

Note: if you are using IExplorer you must submit a HTTP form with POST method to be able to download the file. If not you are going to see the PDF code in the screen. This does not happen in Chrome or Firefox.

<%@ page import="java.io.*, com.lowagie.text.*, com.lowagie.text.pdf.*" %><%

response.setContentType("application/download");
response.setHeader("Content-disposition","attachment;filename=listaPrecios.pdf" );  

// -------- FIRST THE PDF WITH THE INFO ----------
String str = "";
// lots of words
for(int i = 0; i < 800; i++) str += "Hello" + i + " ";
// the document
Document doc = new Document( PageSize.A4, 25, 25, 200, 70 );
ByteArrayOutputStream streamDoc = new ByteArrayOutputStream();
PdfWriter.getInstance( doc, streamDoc );
// lets start filling with info
doc.open();
doc.add(new Paragraph(str));
doc.close();
// the beauty of this is the PDF will have all the pages it needs
PdfReader frente = new PdfReader(streamDoc.toByteArray());
PdfStamper stamperDoc = new PdfStamper( frente, response.getOutputStream());

// -------- THE BACKGROUND PDF FILE -------
// in JBoss the file has to be in webinf/classes to be readed this way
PdfReader fondo = new PdfReader("listaPrecios.pdf");
ByteArrayOutputStream streamFondo = new ByteArrayOutputStream();
PdfStamper stamperFondo = new PdfStamper( fondo, streamFondo);
// the acroform
AcroFields form = stamperFondo.getAcroFields();
// the fields 
form.setField("nombre","Avicultura");
form.setField("descripcion","Esto describe para que sirve la lista ");
stamperFondo.setFormFlattening(true);
stamperFondo.close();
// our background is ready
PdfReader fondoEstampado = new PdfReader( streamFondo.toByteArray() );

// ---- ADDING THE BACKGROUND TO EACH DATA PAGE ---------
PdfImportedPage pagina = stamperDoc.getImportedPage(fondoEstampado,1);
int n = frente.getNumberOfPages();
PdfContentByte background;
for (int i = 1; i <= n; i++) {
    background = stamperDoc.getUnderContent(i);
    background.addTemplate(pagina, 0, 0);
}
// after this everithing will be written in response.getOutputStream()
stamperDoc.close(); 
%>

There is another solution much simpler, and solves your problem. It depends the amount of text you want to add.

// read the file
PdfReader fondo = new PdfReader("listaPrecios.pdf");
PdfStamper stamper = new PdfStamper( fondo, response.getOutputStream());
PdfContentByte content = stamper.getOverContent(1);
// add text
ColumnText ct = new ColumnText( content );
// this are the coordinates where you want to add text
// if the text does not fit inside it will be cropped
ct.setSimpleColumn(50,500,500,50);
ct.setText(new Phrase(str, titulo1));
ct.go();

To be more specific if you are missing the class com.vaadin.external.org.slf4j.LoggerFactory add the below dependency.

<dependency>
    <groupId>com.vaadin.external.slf4j</groupId>
    <artifactId>vaadin-slf4j-jdk14</artifactId>
    <version>1.6.1</version>
</dependency>

If you are missing any other org.slf4j.LoggerFactory, just go to Maven central class name search and search for the exact class name to determine what exact dependency you are missing.

CREATE TABLE dbo.tblUsers
(
    ID INT IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
    UserID AS 'UID' + RIGHT('00000000' + CAST(ID AS VARCHAR(8)), 8) PERSISTED, 
    [Name] VARCHAR(50) NOT NULL,
)

To check if an array is either empty or not

A modern way, ES5+:

if (Array.isArray(array) && array.length) {
    // array exists and is not empty
}

An old-school way:

typeof array != "undefined"
    && array != null
    && array.length != null
    && array.length > 0

A compact way:

if (typeof array != "undefined" && array != null && array.length != null && array.length > 0) {
    // array exists and is not empty
}

A CoffeeScript way:

if array?.length > 0

Why?

Case Undefined
Undefined variable is a variable that you haven't assigned anything to it yet.

let array = new Array();     // "array" !== "array"
typeof array == "undefined"; // => true

Case Null
Generally speaking, null is state of lacking a value. For example a variable is null when you missed or failed to retrieve some data.

array = searchData();  // can't find anything
array == null;         // => true

Case Not an Array
Javascript has a dynamic type system. This means we can't guarantee what type of object a variable holds. There is a chance that we're not talking to an instance of Array.

supposedToBeArray =  new SomeObject();
typeof supposedToBeArray.length;       // => "undefined"

array = new Array();
typeof array.length;                   // => "number"

Case Empty Array
Now since we tested all other possibilities, we're talking to an instance of Array. In order to make sure it's not empty, we ask about number of elements it's holding, and making sure it has more than zero elements.

firstArray = [];
firstArray.length > 0;  // => false

secondArray = [1,2,3];
secondArray.length > 0; // => true

This code works for me:

public void Run()
{
    Dog myDog = new Dog();
    myDog.Name= "Foo";
    myDog.Color = DogColor.Brown;

    System.Console.WriteLine("{0}", myDog.ToString());

    MemoryStream stream = SerializeToStream(myDog);

    Dog newDog = (Dog)DeserializeFromStream(stream);

    System.Console.WriteLine("{0}", newDog.ToString());
}

Where the types are like this:

[Serializable]
public enum DogColor
{
    Brown,
    Black,
    Mottled
}

[Serializable]
public class Dog
{
    public String Name
    {
        get; set;
    }

    public DogColor Color
    {
        get;set;
    }

    public override String ToString()
    {
        return String.Format("Dog: {0}/{1}", Name, Color);
    }
}

and the utility methods are:

public static MemoryStream SerializeToStream(object o)
{
    MemoryStream stream = new MemoryStream();
    IFormatter formatter = new BinaryFormatter();
    formatter.Serialize(stream, o);
    return stream;
}

public static object DeserializeFromStream(MemoryStream stream)
{
    IFormatter formatter = new BinaryFormatter();
    stream.Seek(0, SeekOrigin.Begin);
    object o = formatter.Deserialize(stream);
    return o;
}

Start from m2e 0.13.0 (if not earlier than), you can convert a Java project to Maven project from the context menu. Here is how:

• Right click the Java project to pop up the context menu
• Select Configure > Convert to Maven Project

Here is the detailed steps with screen shots.

Try to use:

location.reload(true);

When this method receives a true value as argument, it will cause the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache.

More info:

• The location object

You can use zip(), which will "interleave" the two arrays together, and then map(), which will apply a function to each element in an iterable:

>>> a = [1,2,3,4,5]
>>> b = [6,7,8,9,10]
>>> zip(a, b)
[(1, 6), (2, 7), (3, 8), (4, 9), (5, 10)]
>>> map(lambda x: x[0] + x[1], zip(a, b))
[7, 9, 11, 13, 15]

I know this is an old post, but I really hate that there is only one answer here that suggests not mixing html and php. Instead of mixing content one should use template systems, or create a basic template system themselves.

In the php

<?php 
  $var1 = 'Alice'; $var2 = 'apples'; $var3 = 'lunch'; $var4 = 'Bob';

  if ($var1 == 'Alice') {
    $html = file_get_contents('/path/to/file.html'); //get the html template
    $template_placeholders = array('##variable1##', '##variable2##', '##variable3##', '##variable4##'); // variable placeholders inside the template
    $template_replace_variables = array($var1, $var2, $var3, $var4); // the variables to pass to the template
    $html_output = str_replace($template_placeholders, $template_replace_variables, $html); // replace the placeholders with the actual variable values.
  }

  echo $html_output;
?>

In the html (/path/to/file.html)

<p>##variable1## ate ##variable2## for ##variable3## with ##variable4##.</p>

The output of this would be:

Alice ate apples for lunch with Bob.

because you are just learning I suggest you practice converting a SELECT joins to UPDATE or DELETE joins. First I suggest you generate a SELECT statement joining these two tables:

SELECT *
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

Then note that we have two table aliases a and b. Using these aliases you can easily generate UPDATE statement to update either table a or b. For table a you have an answer provided by JW. If you want to update b, the statement will be:

UPDATE  b
SET     b.marks = a.marks
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

Now, to convert the statement to a DELETE statement use the same approach. The statement below will delete from a only (leaving b intact) for those records that match by name:

DELETE a
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

You can use the SQL Fiddle created by JW as a playground

yes there is on-mouseover in angular2 instead of ng-Mouseover like in angular 1.x so you have to write this :-

<div on-mouseover='over()' style="height:100px; width:100px; background:#e2e2e2">hello mouseover</div>

over(){
    console.log("Mouseover called");
  }

As @Gunter Suggested in comment there is alternate of on-mouseover we can use this too. Some people prefer the on- prefix alternative, known as the canonical form.

Update

HTML Code -

<div (mouseover)='over()' (mouseout)='out()' style="height:100px; width:100px; background:#e2e2e2">hello mouseover</div>

Controller/.TS Code -

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

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';

  over(){
    console.log("Mouseover called");
  }

  out(){
    console.log("Mouseout called");
  }
}

Working Example

Some other Mouse events can be used in Angular -

(mouseenter)="myMethod()"
(mousedown)="myMethod()"
(mouseup)="myMethod()"

XSD (XML schema definition) defines the element in an XML document. It can be used to verify if the elements in the xml document adheres to the description in which the content is to be placed. While wsdl is specific type of XML document which describes the web service. WSDL itself adheres to a XSD.

index.html

<!DOCTYPE html>
<html>
   <body>
       <form action="submit.php" method="POST">
         First name: <input type="text" name="firstname" /><br /><br />
         Last name: <input type="text" name="lastname" /><br />
         <input type="submit" value="Submit" />
      </form> 
   </body>
</html>

After that one more file which page you want to display after pressing the submit button

submit.php

<html>
  <body>

    Your First Name is -  <?php echo $_POST["firstname"]; ?><br>
    Your Last Name is -   <?php echo $_POST["lastname"]; ?>

  </body>
</html>

You have two records in your json file, and json.loads() is not able to decode more than one. You need to do it record by record.

See Python json.loads shows ValueError: Extra data

OR you need to reformat your json to contain an array:

{
    "foo" : [
       {"name": "XYZ", "address": "54.7168,94.0215", "country_of_residence": "PQR", "countries": "LMN;PQRST", "date": "28-AUG-2008", "type": null},
       {"name": "OLMS", "address": null, "country_of_residence": null, "countries": "Not identified;No", "date": "23-FEB-2017", "type": null}
    ]
}

would be acceptable again. But there cannot be several top level objects.

<input type="checkbox" name="check_list[<? echo $row['Report ID'] ?>]" value="<? echo $row['Report ID'] ?>">

And after the post, you can loop through them:

   if(!empty($_POST['check_list'])){
     foreach($_POST['check_list'] as $report_id){
        echo "$report_id was checked! ";
     }
   }

Or get a certain value posted from previous page:

if(isset($_POST['check_list'][$report_id])){
  echo $report_id . " was checked!<br/>";
}

You are looking for the SO_KEEPALIVE socket option.

The Java Socket API exposes "keep-alive" to applications via the setKeepAlive and getKeepAlive methods.

EDIT: SO_KEEPALIVE is implemented in the OS network protocol stacks without sending any "real" data. The keep-alive interval is operating system dependent, and may be tuneable via a kernel parameter.

Since no data is sent, SO_KEEPALIVE can only test the liveness of the network connection, not the liveness of the service that the socket is connected to. To test the latter, you need to implement something that involves sending messages to the server and getting a response.

Check the site's Application Pool in IIS / Application Pools / YourPool / Advanced Settings :

• Advanced / Enable 32-Bit Applications: True

There's some anecdotal evidence to suggest you do this too:

• Managed Pipeline Mode : Classic

Why not a/b/(c|d|e)? I just tried with Saxon XML library (wrapped up nicely with some Clojure goodness), and it seems to work. abc.xml is the doc described by OP.

(require '[saxon :as xml])
(def abc-doc (xml/compile-xml (slurp "abc.xml")))
(xml/query "a/b/(c|d|e)" abc-doc)
=> (#<XdmNode <c>C1</c>>
    #<XdmNode <d>D1</d>>
    #<XdmNode <e>E1</e>>
    #<XdmNode <c>C2</c>>
    #<XdmNode <d>D2</d>>
    #<XdmNode <e>E1</e>>)

valgrind --log-file="filename"

I think this is what you want:

document.getElementById('tag-id').innerHTML = '<ol><li>html data</li></ol>';

Keep in mind that innerHTML is not accessible for all types of tags when using IE. (table elements for example)

Adding to the answers above, for those who want a quick way to use an external USB device (HDD, flash drive) working inside docker, and not using priviledged mode:

Find the devpath to your device on the host:

sudo fdisk -l

You can recognize your drive by it's capacity quite easily from the list. Copy this path (for the following example it is /dev/sda2).

Disque /dev/sda2 : 554,5 Go, 57151488 octets, 111624 secteurs
Unités : secteur de 1 × 512 = 512 octets
Taille de secteur (logique / physique) : 512 octets / 512 octets
taille d'E/S (minimale / optimale) : 512 octets / 512 octets

Mount this devpath (preferable to /media):

sudo mount <drive path> /media/<mount folder name>

You can then use this either as a param to docker run like:

docker run -it -v /media/<mount folder name>:/media/<mount folder name>

or in docker compose under volumes:

services:
  whatevermyserviceis:
    volumes:
      - /media/<mount folder name>:/media/<mount folder name>

And now when you run and enter your container, you should be able to access the drive inside the container at /media/<mount folder name>

DISCLAIMER:

1. This will probably not work for serial devices such as webcams etc. I have only tested this for USB storage drives.
2. If you need to reconnect and disconnect devices regularly, this method would be annoying, and also would not work unless you reset the mount path and restart the container.
3. I used docker 17.06 + as prescribed in the docs

go to... 
C:\wamp\alias

Inside alias folder you will see some files like phpmyadmin,phpsysinfo,etc...

open each file, and you can see inside file some commented instruction are give to access from outside ,like to give access to phpmyadmin from outside replace the lines

Here's my ultimate answer to this.

Also apparently javascript's new Date(year, month, day) constructor doesn't account for leap seconds too.

// Parses an Excel Date ("serial") into a
// corresponding javascript Date in UTC+0 timezone.
//
// Doesn't account for leap seconds.
// Therefore is not 100% correct.
// But will do, I guess, since we're
// not doing rocket science here.
//
// https://www.pcworld.com/article/3063622/software/mastering-excel-date-time-serial-numbers-networkdays-datevalue-and-more.html
// "If you need to calculate dates in your spreadsheets,
//  Excel uses its own unique system, which it calls Serial Numbers".
//
lib.parseExcelDate = function (excelSerialDate) {
  // "Excel serial date" is just
  // the count of days since `01/01/1900`
  // (seems that it may be even fractional).
  //
  // The count of days elapsed
  // since `01/01/1900` (Excel epoch)
  // till `01/01/1970` (Unix epoch).
  // Accounts for leap years
  // (19 of them, yielding 19 extra days).
  const daysBeforeUnixEpoch = 70 * 365 + 19;

  // An hour, approximately, because a minute
  // may be longer than 60 seconds, see "leap seconds".
  const hour = 60 * 60 * 1000;

  // "In the 1900 system, the serial number 1 represents January 1, 1900, 12:00:00 a.m.
  //  while the number 0 represents the fictitious date January 0, 1900".
  // These extra 12 hours are a hack to make things
  // a little bit less weird when rendering parsed dates.
  // E.g. if a date `Jan 1st, 2017` gets parsed as
  // `Jan 1st, 2017, 00:00 UTC` then when displayed in the US
  // it would show up as `Dec 31st, 2016, 19:00 UTC-05` (Austin, Texas).
  // That would be weird for a website user.
  // Therefore this extra 12-hour padding is added
  // to compensate for the most weird cases like this
  // (doesn't solve all of them, but most of them).
  // And if you ask what about -12/+12 border then
  // the answer is people there are already accustomed
  // to the weird time behaviour when their neighbours
  // may have completely different date than they do.
  //
  // `Math.round()` rounds all time fractions
  // smaller than a millisecond (e.g. nanoseconds)
  // but it's unlikely that an Excel serial date
  // is gonna contain even seconds.
  //
  return new Date(Math.round((excelSerialDate - daysBeforeUnixEpoch) * 24 * hour) + 12 * hour);
};

When you say

val map = scala.collection.mutable.Map

you are not creating a map instance, but instead aliasing the Map type.

map: collection.mutable.Map.type = scala.collection.mutable.Map$@fae93e

Try instead the following:

scala> val map = scala.collection.mutable.Map[String, Int]()
map: scala.collection.mutable.Map[String,Int] = Map()

scala> map("asdf") = 9

scala> map
res6: scala.collection.mutable.Map[String,Int] = Map((asdf,9))

Use btn-primary-spacing class for all buttons remove margin-left class

Example :

<button type="button" class="btn btn-primary btn-color btn-bg-color btn-sm col-xs-2 btn-primary-spacing">
  <span class="glyphicon glyphicon-plus" aria-hidden="true"></span> ADD PACKET
</button>

CSS will be like :

.btn-primary-spacing 
{
margin-right: 5px;
margin-bottom: 5px !important;
}

Or, if you can use a DataGridView, you could just call Sort(column, direction):

namespace Sorter
{
    using System;
    using System.ComponentModel;
    using System.Windows.Forms;

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.dataGridView1.Rows.Add("Abc", 5);
            this.dataGridView1.Rows.Add("Def", 8);
            this.dataGridView1.Rows.Add("Ghi", 3);
            this.dataGridView1.Sort(this.dataGridView1.Columns[1], 
                                    ListSortDirection.Ascending);
        }
    }
}

Which would give you the desired result:

I've had a very similar issue using spring-boot-starter-data-redis. To my implementation there was offered a @Bean for RedisTemplate as follows:

@Bean
public RedisTemplate<String, List<RoutePlantCache>> redisTemplate(RedisConnectionFactory connectionFactory) {
    final RedisTemplate<String, List<RoutePlantCache>> template = new RedisTemplate<>();
    template.setConnectionFactory(connectionFactory);
    template.setKeySerializer(new StringRedisSerializer());
    template.setValueSerializer(new Jackson2JsonRedisSerializer<>(RoutePlantCache.class));

    // Add some specific configuration here. Key serializers, etc.
    return template;
}

The fix was to specify an array of RoutePlantCache as following:

template.setValueSerializer(new Jackson2JsonRedisSerializer<>(RoutePlantCache[].class));

Below the exception I had:

apt-cyg is a great installer similar to apt-get to easily install any packages for Cygwin.

$ apt-cyg install curl

Note: apt-cyg should be first installed. You can do this from Windows command line:

cd c:\cygwin
cygwinsetup.exe -q -P wget,tar,qawk, bzip2,vim,lynx

Close Windows cmd, and open Cygwin Bash.

$ lynx -source rawgit.com/transcode-open/apt-cyg/master/apt-cyg > apt-cyg install apt-cyg /bin
$ chmod +x /bin/apt-cyg

Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):

The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file

So I'd go for that one.

Alex mentioned memory efficiency, and Roberto mentions convenience, and these are both good points. For a few more ideas, I'll mention speed and functionality.

Functionality: You get a lot built in with NumPy, FFTs, convolutions, fast searching, basic statistics, linear algebra, histograms, etc. And really, who can live without FFTs?

Speed: Here's a test on doing a sum over a list and a NumPy array, showing that the sum on the NumPy array is 10x faster (in this test -- mileage may vary).

from numpy import arange
from timeit import Timer

Nelements = 10000
Ntimeits = 10000

x = arange(Nelements)
y = range(Nelements)

t_numpy = Timer("x.sum()", "from __main__ import x")
t_list = Timer("sum(y)", "from __main__ import y")
print("numpy: %.3e" % (t_numpy.timeit(Ntimeits)/Ntimeits,))
print("list:  %.3e" % (t_list.timeit(Ntimeits)/Ntimeits,))

which on my systems (while I'm running a backup) gives:

You have to check which Python you are using. I had the same problem because the Python I was using was not the same one that brew was using. In your command line:

1. which python
   output: /usr/bin/python
2. which brew
   output: /usr/local/bin/brew     //so they are different
3. cd /usr/local/lib/python2.7/site-packages
4. ls   //you can see PyQt4 and sip are here
5. Now you need to add usr/local/lib/python2.7/site-packages to your python path.
6. open ~/.bash_profile   //you will open your bash_profile file in your editor
7. Add 'export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH' to your bash file and save it
8. Close your terminal and restart it to reload the shell
9. python
10. import PyQt4    // it is ok now

Here's a Vanilla JavaScript solution:

(function init() {_x000D_
_x000D_
  var cells = document.getElementsByClassName("cell");_x000D_
_x000D_
  for(let index = 0; index < cells.length; ++index) {_x000D_
    let cell = cells.item(index);_x000D_
    cell.addEventListener('mouseenter', setTitleIfNecessary, false);_x000D_
  }_x000D_
_x000D_
  function setTitleIfNecessary() {_x000D_
    if(this.offsetWidth < this.scrollWidth) {_x000D_
      this.setAttribute('title', this.innerHTML);_x000D_
    }_x000D_
  }_x000D_
_x000D_
})();

.cell {_x000D_
  white-space: nowrap;_x000D_
  overflow: hidden;_x000D_
  text-overflow: ellipsis;_x000D_
  border: 1px;_x000D_
  border-style: solid;_x000D_
  width: 120px; _x000D_
}

<div class="cell">hello world!</div>_x000D_
<div class="cell">hello mars! kind regards, world</div>

You need to chain the method like this:

$('#input').val('test').change();

Further to Ryan's answer you will also need to set the DataColumn's Ordinal property if you are dealing with a table-valued parameter with multiple columns whose ordinals are not in alphabetical order.

As an example, if you have the following table value that is used as a parameter in SQL:

CREATE TYPE NodeFilter AS TABLE (
  ID int not null
  Code nvarchar(10) not null,
);

You would need to order your columns as such in C#:

table.Columns["ID"].SetOrdinal(0);
// this also bumps Code to ordinal of 1
// if you have more than 2 cols then you would need to set more ordinals

If you fail to do this you will get a parse error, failed to convert nvarchar to int.

you need double quotes in all your three if statements, eg.:

IF "%a%"=="2" (

@echo OFF &SETLOCAL ENABLEDELAYEDEXPANSION
cls
title ~USB Wizard~
echo What do you want to do?
echo 1.Enable/Disable USB Storage Devices.
echo 2.Enable/Disable Writing Data onto USB Storage.
echo 3.~Yet to come~.


set "a=%globalparam1%"
goto :aCheck
:aPrompt
set /p "a=Enter Choice: "
:aCheck
if "%a%"=="" goto :aPrompt
echo %a%

IF "%a%"=="2" (
    title USB WRITE LOCK
    echo What do you want to do?
    echo 1.Apply USB Write Protection
    echo 2.Remove USB Write Protection
    ::param1
    set "param1=%globalparam2%"
    goto :param1Check
    :param1Prompt
    set /p "param1=Enter Choice: "
    :param1Check
    if "!param1!"=="" goto :param1Prompt

    if "!param1!"=="1" (
         REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies\ /v WriteProtect /t REG_DWORD /d 00000001
         USB Write is Locked!
    )
    if "!param1!"=="2" (
         REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies\ /v WriteProtect /t REG_DWORD /d 00000000
         USB Write is Unlocked!
    )
)
pause

a = [5, 1, 6, 14, 2, 8]
b = [2, 6, 15]

a - b
# => [5, 1, 14, 8]

Use rsync so that you can continue if the connection gets broken. And if something changes you can copy them much faster too!

Rsync works with SSH so your copy operation is secure.

Could you just draw an svg path inside of a span using document.write? The span isn't required for the svg to work, it just ensures that the svg remains inline with whatever text the carat is next to. I used margin-bottom to vertically center it with the text, there might be another way to do that though. This is what I did on my blog's side nav (minus the js). If you don't have text next to it you wouldn't need the span or the margin-bottom offset.

<div id="ID"></div>

<script type="text/javascript">
var x = document.getElementById('ID');

// your "margin-bottom" is the negative of 1/2 of the font size (in this example the font size is 16px)
// change the "stroke=" to whatever color your font is too
x.innerHTML = document.write = '<span><svg style="margin-bottom: -8px; height: 30px; width: 25px;" viewBox="0,0,100,50"><path fill="transparent" stroke-width="4" stroke="black" d="M20 10 L50 40 L80 10"/></svg></span>';
</script>

You can append to your PATH in a minimal fashion. No need for parentheses unless you're appending more than one element. It also usually doesn't need quotes. So the simple, short way to append is:

path+=/some/new/bin/dir

This lower-case syntax is using path as an array, yet also affects its upper-case partner equivalent, PATH (to which it is "bound" via typeset).

(Notice that no : is needed/wanted as a separator.)

Common interactive usage

Then the common pattern for testing a new script/executable becomes:

path+=$PWD/.
# or
path+=$PWD/bin

Common config usage

You can sprinkle path settings around your .zshrc (as above) and it will naturally lead to the earlier listed settings taking precedence (though you may occasionally still want to use the "prepend" form path=(/some/new/bin/dir $path)).

Related tidbits

Treating path this way (as an array) also means: no need to do a rehash to get the newly pathed commands to be found.

Also take a look at vared path as a dynamic way to edit path (and other things).

You may only be interested in path for this question, but since we're talking about exports and arrays, note that arrays generally cannot be exported.

You can even prevent PATH from taking on duplicate entries (refer to this and this):

typeset -U path

You could just re-direct specific numbers in your contacts to your voice-mail. That's already supported.

Otherwise I guess the documentation for 'Contacts' would be a good place to start looking.

You can also do like this:

  var mocha = require('mocha')
  var describe = mocha.describe
  var it = mocha.it
  var assert = require('chai').assert

  describe('#indexOf()', function() {
    it('should return -1 when not present', function() {
      assert.equal([1,2,3].indexOf(4), -1)
    })
  })

Reference: http://mochajs.org/#require

Constants can be declare outside of classes and use within your class. Otherwise the get property is a nice workaround

const MY_CONSTANT: string = "wazzup";

export class MyClass {

    public myFunction() {

        alert(MY_CONSTANT);
    }
}

Just this

passwd <<EOF
oldpassword
newpassword
newpassword
EOF

Actual output from ubuntu machine (sorry no AIX available to me):

user@host:~$ passwd <<EOF
oldpassword
newpassword
newpassword
EOF

Changing password for user.
(current) UNIX password: Enter new UNIX password: Retype new UNIX password: 
passwd: password updated successfully
user@host:~$

Try:

SELECT DATE(`date_time_field`) AS date_part, TIME(`date_time_field`) AS time_part FROM `your_table`

While the answer from alireza is correct, it has one gotcha:

You can't install Microsoft Visual C++ 2015 redist (runtime) unless you have Windows Update KB2999226 installed (at least on Windows 7 64-bit SP1).

You can't do that if USER is defined as a quoted string.

But you can do that if USER is just JACK or QUEEN or Joker or whatever.

There are two tricks to use:

1. Token-splicing, where you combine an identifier with another identifier by just concatenating their characters. This allows you to compare against JACK without having to #define JACK to something
2. variadic macro expansion, which allows you to handle macros with variable numbers of arguments. This allows you to expand specific identifiers into varying numbers of commas, which will become your string comparison.

So let's start out with:

#define JACK_QUEEN_OTHER(u) EXPANSION1(ReSeRvEd_, u, 1, 2, 3)

Now, if I write JACK_QUEEN_OTHER(USER), and USER is JACK, the preprocessor turns that into EXPANSION1(ReSeRvEd_, JACK, 1, 2, 3)

Step two is concatenation:

#define EXPANSION1(a, b, c, d, e) EXPANSION2(a##b, c, d, e)

Now JACK_QUEEN_OTHER(USER) becomes EXPANSION2(ReSeRvEd_JACK, 1, 2, 3)

This gives the opportunity to add a number of commas according to whether or not a string matches:

#define ReSeRvEd_JACK x,x,x
#define ReSeRvEd_QUEEN x,x

If USER is JACK, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(x,x,x, 1, 2, 3)

If USER is QUEEN, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(x,x, 1, 2, 3)

If USER is other, JACK_QUEEN_OTHER(USER) becomes EXPANSION2(ReSeRvEd_other, 1, 2, 3)

At this point, something critical has happened: the fourth argument to the EXPANSION2 macro is either 1, 2, or 3, depending on whether the original argument passed was jack, queen, or anything else. So all we have to do is pick it out. For long-winded reasons, we'll need two macros for the last step; they'll be EXPANSION2 and EXPANSION3, even though one seems unnecessary.

Putting it all together, we have these 6 macros:

#define JACK_QUEEN_OTHER(u) EXPANSION1(ReSeRvEd_, u, 1, 2, 3)
#define EXPANSION1(a, b, c, d, e) EXPANSION2(a##b, c, d, e)
#define EXPANSION2(a, b, c, d, ...) EXPANSION3(a, b, c, d)
#define EXPANSION3(a, b, c, d, ...) d
#define ReSeRvEd_JACK x,x,x
#define ReSeRvEd_QUEEN x,x

And you might use them like this:

int main() {
#if JACK_QUEEN_OTHER(USER) == 1
  printf("Hello, Jack!\n");
#endif
#if JACK_QUEEN_OTHER(USER) == 2
  printf("Hello, Queen!\n");
#endif
#if JACK_QUEEN_OTHER(USER) == 3
  printf("Hello, who are you?\n");
#endif
}

MSVC Update: You have to parenthesize slightly differently to make things also work in MSVC. The EXPANSION* macros look like this:

#define EXPANSION1(a, b, c, d, e) EXPANSION2((a##b, c, d, e))
#define EXPANSION2(x) EXPANSION3 x
#define EXPANSION3(a, b, c, d, ...) d

How about this:

$(":submit").closest("form").submit(function(){
    $(':submit').attr('disabled', 'disabled');
});

This should disable all forms with submit buttons in your app.

my_var: the variable declared

VAR: the variable, whose value is to be checked

param_1, param_2: values of the variable VAR

value_1, value_2, value_3: the values to be assigned to my_var according to the values of my_var

my_var: "{{ 'value_1' if VAR == 'param_1' else 'value_2' if VAR == 'param_2' else 'value_3' }}"

Although I like fhucho's recommendation of

String.valueOf(i)

The irony is that this method actually calls

Integer.toString(i)

Thus, use String.valueOf(i) if you like how it reads and you don't need radix, but also knowing that it is less efficient than Integer.toString(i).

Use transparent background color for the modalbottomsheet and give separate color for box decoration

   showModalBottomSheet(
      backgroundColor: Colors.transparent,
      context: context, builder: (context) {
    return Container(

      decoration: BoxDecoration(
        color: Colors.white,
        borderRadius: BorderRadius.only(
            topLeft:Radius.circular(40) ,
            topRight: Radius.circular(40)
        ),
      ),
      padding: EdgeInsets.symmetric(vertical: 20,horizontal: 60),
      child: Settings_Form(),
    );
  });

The value of event handler attributes such as onclick should just be JavaScript, without any "javascript:" prefix. The javascript: pseudo-protocol is used in a URL, for example:

<a href="javascript:func(this)">here</a>

You should use the onclick="func(this)" form in preference to this though. Also note that in my example above using the javascript: pseudo-protocol "this" will refer to the window object rather than the <a> element.

A property can be declared in two ways.

• Creating the getter, setter methods for an attribute and then passing these as argument to property function
• Using the @property decorator.

You can have a look at few examples I have written about properties in python.

Here is the simple solution by StreamEx:

StreamEx.of(list).groupingBy(Function.identity(), MoreCollectors.countingInt());

This has the advantage of reducing the Java stream boilerplate code: collect(Collectors.

In WSDL definition, bindings contain operations, here comes style for each operation.

Document : In WSDL file, it specifies types details either having inline Or imports XSD document, which describes the structure(i.e. schema) of the complex data types being exchanged by those service methods which makes loosely coupled. Document style is default.

• Advantage:
  • Using this Document style, we can validate SOAP messages against predefined schema. It supports xml datatypes and patterns.
  • loosely coupled.
• Disadvantage: It is a little bit hard to get understand.

In WSDL types element looks as follows:

<types>
 <xsd:schema>
  <xsd:import schemaLocation="http://localhost:9999/ws/hello?xsd=1" namespace="http://ws.peter.com/"/>
 </xsd:schema>
</types>

The schema is importing from external reference.

RPC :In WSDL file, it does not creates types schema, within message elements it defines name and type attributes which makes tightly coupled.

<types/>  
<message name="getHelloWorldAsString">  
<part name="arg0" type="xsd:string"/>  
</message>  
<message name="getHelloWorldAsStringResponse">  
<part name="return" type="xsd:string"/>  
</message>  

• Advantage: Easy to understand.
• Disadvantage:
  • we can not validate SOAP messages.
  • tightly coupled

RPC : No types in WSDL
Document: Types section would be available in WSDL

In addition to adding 127.0.0.1 localhost to your hosts file, make the following changes in Eclipse.

Under

Window -> Preferences -> Android -> DDMS

Set Base local debugger port to 8601

Check the box that says Use ADBHOST and the value should be 127.0.0.1 Thanks to Ben Clayton & Doguhan Uluca in the comments for leading me to a solution.

Some Google keywords:

Ailment or solution for Nexus S Android debugging with the error message: Can't bind to local 8600 for debugger.

Here's the FIDDLE

Same code as yours but it will work on dynamically created elements.

$(document).on('click', '.deletelanguage', function () {
    alert("success");
    $('#LangTable').append(' <br>------------<br> <a class="deletelanguage">Now my class is deletelanguage. click me to test it is not working.</a>');
});

This actually does cause a problem because line endings are automatically modified dirtying files without making any changes to them. See this post for resolution.

git replacing LF with CRLF

You can also use RedirectMatch directive to deny access to a folder.

To deny access to a folder, you can use the following RedirectMatch in htaccess :

 RedirectMatch 403 ^/folder/?$

This will forbid an external access to /folder/ eg : http://example.com/folder/ will return a 403 forbidden error.

To deny access to everything inside the folder, You can use this :

RedirectMatch 403 ^/folder/.*$

This will block access to the entire folder eg : http://example.com/folder/anyURI will return a 403 error response to client.

Sorry for replying on an older question, but I would like to clarify the last question.

You use a "get" method for your form. When the name of your input-field is "g", it will make a URL like this:

https://www.google.com/search?g=[value from input-field]

But when you search with google, you notice the following URL:

https://www.google.nl/search?q=google+search+bar

Google uses the "q" Querystring variable as it's search-query. Therefor, renaming your field from "g" to "q" solved the problem.

Yes, you can.

From cplusplus.com:

Because these functions are operator overloading functions, the usual way in which they are called is:

   strm >> variable;

Where strm is the identifier of a istream object and variable is an object of any type supported as right parameter. It is also possible to call a succession of extraction operations as:

   strm >> variable1 >> variable2 >> variable3; //...

which is the same as performing successive extractions from the same object strm.

Just replace strm with cin.

I was struggling with this issue for several hours, i have read every relevant topic and found out that the error was caused because under the privacy settings of my device, the camera access to my app was blocked!!! I have never denied access to camera and i don't know how it was blocked but that was the problem!

Try:

if (record.has("problemkey") && !record.isNull("problemkey")) {
    // Do something with object.
}

Zalgo text works because of combining characters. These are special characters that allow to modify character that comes before.

OR

y + ̆ = y̆ which actually is

y + ̆ = y̆

Since you can stack them one atop the other you can produce the following:

y̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

which actually is:

y̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

The same goes for putting stuff underneath:

y̰̰̰̰̰̰̰̰̰̰̰̰̰̰̰̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

that in fact is:

y̰̰̰̰̰̰̰̰̰̰̰̰̰̰̰̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

In Unicode, the main block of combining diacritics for European languages and the International Phonetic Alphabet is U+0300–U+036F.

More about it here

To produce a list of combining diacritical marks you can use the following script (since links keep on dying)

for(var i=768; i<879; i++){console.log(new DOMParser().parseFromString("&#"+i+";", "text/html").documentElement.textContent +"  "+"&#"+i+";");}

You could also use the parse_date_time function from the lubridate package:

library(lubridate)
day<-"31/08/2011"
as.Date(parse_date_time(day,"dmy"))
[1] "2011-08-31"

parse_date_time returns a POSIXct object, so we use as.Date to get a date object. The first argument of parse_date_time specifies a date vector, the second argument specifies the order in which your format occurs. The orders argument makes parse_date_time very flexible.

Recent bash versions allow fall-through by using ;& in stead of ;;: they also allow resuming the case checks by using ;;& there.

for n in 4 14 24 34
do
  echo -n "$n = "
  case "$n" in
   3? )
     echo -n thirty-
     ;;&   #resume (to find ?4 later )
   "24" )
     echo -n twenty-
     ;&   #fallthru
   "4" | [13]4)
     echo -n four 
     ;;&  # resume ( to find teen where needed )
   "14" )
     echo -n teen
  esac
  echo 
done

sample output

4 = four
14 = fourteen
24 = twenty-four
34 = thirty-four

In my case, i imported wrong, In module place instead of importing module(DemoModule) imported routing module(DemoRoutingModule)

Wrong Import:

const routes: Routes = [
  {
  path: '', component: ContentComponent,
  children: [
  { path: '', redirectTo: 'demo' },
  { path: 'demo', loadChildren : () => import('../content/demo/demo-routing.module').then(m => m.DemoRoutingModule)}]
  }

Right Code

const routes: Routes = [

  { path: 'demo', loadChildren : () => import('../content/demo/demo.module').then(m => m.DemoModule)}]

By the time the image is loaded, the renderer has already drawn the scene, hence it is too late. The solution is to change

texture = THREE.ImageUtils.loadTexture('crate.gif'),

into

texture = THREE.ImageUtils.loadTexture('crate.gif', {}, function() {
    renderer.render(scene);
}),

edit 2018: This is outdated, js and typescript now have for..of loops.
http://www.typescriptlang.org/docs/handbook/iterators-and-generators.html

The book "TypeScript Revealed" says

"You can iterate through the items in an array by using either for or for..in loops as demonstrated here:

// standard for loop
for (var i = 0; i < actors.length; i++)
{
  console.log(actors[i]);
}

// for..in loop
for (var actor in actors)
{
  console.log(actor);
}

"

Turns out, the second loop does not pass the actors in the loop. So would say this is plain wrong. Sadly it is as above, loops are untouched by typescript.

map and forEach often help me and are due to typescripts enhancements on function definitions more approachable, lke at the very moment:

this.notes = arr.map(state => new Note(state));

My wish list to TypeScript;

1. Generic collections
2. Iterators (IEnumerable, IEnumerator interfaces would be best)

When in a jar file, the resource is located absolutely in the package hierarchy (not file system hierarchy). So if you have class com.example.Sweet loading a resource named "./default.conf" then the resource's name is specified as "/com/example/default.conf".

But if it's in a jar then it's not a File ...

You should include <string.h> (or its C++ equivalent, <cstring>).

1. Go to device manager and check hardware id's.
2. Check if the usb.inf file has the device listed in it
3. If not, add the device hardware id and install it from the device manager.

It may depend on what you consider fallthrough. I'm ok with this sort of thing:

switch (value)
{
  case 0:
    result = ZERO_DIGIT;
    break;

  case 1:
  case 3:
  case 5:
  case 7:
  case 9:
     result = ODD_DIGIT;
     break;

  case 2:
  case 4:
  case 6:
  case 8:
     result = EVEN_DIGIT;
     break;
}

But if you have a case label followed by code that falls through to another case label, I'd pretty much always consider that evil. Perhaps moving the common code to a function and calling from both places would be a better idea.

And please note that I use the C++ FAQ definition of "evil"

In case if you are using node js, then this could be the possible solution

const express = require("express");
const app = express();
const server = app.listen(8080);
server.keepAliveTimeout = 61 * 1000;

https://medium.com/hk01-tech/running-eks-in-production-for-2-years-the-kubernetes-journey-at-hk01-68130e603d76

you can even write it just like this:

<a href="javascript:void(0);"></a>

im not sure its a better way but it is a way :)

Looked around online too long not to contribute. After trying to type in the mysql prompt from the command line, I was continuing to receive this message:

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

This was due to the fact that my local mysql server was no longer running. In order to restart the server, I navigated to

shell> cd /user/local/bin

where my mysql.server was located. From here, simply type:

shell> mysql.server start

This will relaunch the local mysql server.

From there you can reset the root password if need be..

mysql> UPDATE mysql.user SET Password=PASSWORD('MyNewPass')
->                   WHERE User='root';
mysql> FLUSH PRIVILEGES;

We can directly subtract dates to get difference in Days.

Update: Note that this answer is pretty ineffective now. The Garbage Collector acts aggressively on SoftReference and WeakReference, so this code is NOT suitable for new apps. (Instead, try libraries like Universal Image Loader suggested in other answers.)

Thanks to James for the code, and Bao-Long for the suggestion of using SoftReference. I implemented the SoftReference changes on James' code. Unfortunately SoftReferences caused my images to be garbage collected too quickly. In my case it was fine without the SoftReference stuff, because my list size is limited and my images are small.

There's a discussion from a year ago regarding the SoftReferences on google groups: link to thread. As a solution to the too-early garbage collection, they suggest the possibility of manually setting the VM heap size using dalvik.system.VMRuntime.setMinimumHeapSize(), which is not very attractive to me.

public DrawableManager() {
    drawableMap = new HashMap<String, SoftReference<Drawable>>();
}

public Drawable fetchDrawable(String urlString) {
    SoftReference<Drawable> drawableRef = drawableMap.get(urlString);
    if (drawableRef != null) {
        Drawable drawable = drawableRef.get();
        if (drawable != null)
            return drawable;
        // Reference has expired so remove the key from drawableMap
        drawableMap.remove(urlString);
    }

    if (Constants.LOGGING) Log.d(this.getClass().getSimpleName(), "image url:" + urlString);
    try {
        InputStream is = fetch(urlString);
        Drawable drawable = Drawable.createFromStream(is, "src");
        drawableRef = new SoftReference<Drawable>(drawable);
        drawableMap.put(urlString, drawableRef);

                + drawable.getIntrinsicHeight() + "," + drawable.getIntrinsicWidth() + ", "
                + drawable.getMinimumHeight() + "," + drawable.getMinimumWidth());
        return drawableRef.get();

You can run composer show -i (short for --installed).

In the latest version just use composer show.

The -i options has been deprecated.

You can also use the global instalation of composer: composer global show

Update: This should probably be the accepted answer since maxElement appeared in Swift.

Use the almighty reduce:

let nums = [1, 6, 3, 9, 4, 6];
let numMax = nums.reduce(Int.min, { max($0, $1) })

Similarly:

let numMin = nums.reduce(Int.max, { min($0, $1) })

reduce takes a first value that is the initial value for an internal accumulator variable, then applies the passed function (here, it's anonymous) to the accumulator and each element of the array successively, and stores the new value in the accumulator. The last accumulator value is then returned.

Try this:

MyObject obj = new MyObject();
if(obj instanceof MyObject){System.out.println("true");} //true

Because of inheritance this is valid for interfaces, too:

class Animal {}
class Dog extends Animal {}    

Dog obj = new Dog();
Animal animal = new Dog();
if(obj instanceof Animal){System.out.println("true");} //true
if(animal instanceof Animal){System.out.println("true");} //true
if(animal instanceof Dog){System.out.println("true");} //true

To find them, you can use this

;WITH cte AS
(
   SELECT 0 AS CharCode
   UNION ALL
   SELECT CharCode + 1 FROM cte WHERE CharCode <31
)
SELECT
   *
FROM
   mytable T
     cross join cte
WHERE
   EXISTS (SELECT *
        FROM mytable Tx
        WHERE Tx.PKCol = T.PKCol
             AND
              Tx.MyField LIKE '%' + CHAR(cte.CharCode) + '%'
         )

Replacing the EXISTS with a JOIN will allow you to REPLACE them, but you'll get multiple rows... I can't think of a way around that...

I would make your final select as:

SELECT    EmplID
        , EmplName
        , InTime
        , [TimeOut]
        , [DateVisited]
        , CONVERT(varchar(3),DATEDIFF(minute,InTime, TimeOut)/60) + ':' +
          RIGHT('0' + CONVERT(varchar(2),DATEDIFF(minute,InTime,TimeOut)%60),2)
          as TotalHours
from times
Order By EmplID, DateVisited 

Any solution trying to use DATEDIFF(hour,... is bound to be complicated (if it's correct) because DATEDIFF counts transitions - DATEDIFF(hour,...09:59',...10:01') will return 1 because of the transition of the hour from 9 to 10. So I'm just using DATEDIFF on minutes.

The above can still be subtly wrong if seconds are involved (it can slightly overcount because its counting minute transitions) so if you need second or millisecond accuracy you need to adjust the DATEDIFF to use those units and then apply suitable division constants (as per the hours one above) to just return hours and minutes.

These spacing notations are quite effective in custom changes. You can also use negative values there too. Official

Though we can use them whenever we want. Bootstrap Spacing

For having a trasition effect like a highlighter just to highlight the text and fade off the bg color, we used the following:

I think there is already a number of answers related to this post, but one can use this which is easy to use just like plugin and also easily readable for programmers. Send your specific date, and get its value in string form:

public string RelativeDateTimeCount(DateTime inputDateTime)
{
    string outputDateTime = string.Empty;
    TimeSpan ts = DateTime.Now - inputDateTime;

    if (ts.Days > 7)
    { outputDateTime = inputDateTime.ToString("MMMM d, yyyy"); }

    else if (ts.Days > 0)
    {
        outputDateTime = ts.Days == 1 ? ("about 1 Day ago") : ("about " + ts.Days.ToString() + " Days ago");
    }
    else if (ts.Hours > 0)
    {
        outputDateTime = ts.Hours == 1 ? ("an hour ago") : (ts.Hours.ToString() + " hours ago");
    }
    else if (ts.Minutes > 0)
    {
        outputDateTime = ts.Minutes == 1 ? ("1 minute ago") : (ts.Minutes.ToString() + " minutes ago");
    }
    else outputDateTime = "few seconds ago";

    return outputDateTime;
}
