You must add the declaration

At the top of your document.

Without it, jquery tends to put the dialog on the bottom of the page and errors may occur when trying to drag it.

exponent is a 1D array. This means that exponent[0] is a scalar, and exponent[0][i] is trying to access it as if it were an array.

Did you mean to say:

L = identity(len(l))
for i in xrange(len(l)):
    L[i][i] = exponent[i]

or even

L = diag(exponent)

?

The second one causes a new char array to be created, and all chars from the String to be copied to this new char array, so I would guess that the first one is faster (and less memory-hungry).

With new version of Lombok you can compile that cute class:

@Value(staticConstructor = "of") public class Pair <E> {
  E first, second;
}

and use it like: Pair<Value> pairOfValues = Pair.of(value1, value2);

Trust me, I am not joking. Remove all the System.Runtime dependencies from your app.config and it will start working.

I'm planning to static import the following to allow for the method reference to be used inline:

public static <T> Predicate<T> not(Predicate<T> t) {
    return t.negate();
}

e.g.

Stream<String> s = ...;
long nonEmptyStrings = s.filter(not(String::isEmpty)).count();

Update: Starting from Java-11, the JDK offers a similar solution built-in as well.

Use overloaded version of indexOf(), which takes the starting index (fromIndex) as 2nd parameter:

str.indexOf("is", str.indexOf("is") + 1);

You can do this without modifying the html. http://jsfiddle.net/8JwhZ/1085/

<div class="title">
<span>Cumulative performance</span>
<span>20/02/2011</span>
</div>

.title span:nth-of-type(1) { float:right }
.title span:nth-of-type(2) { float:left }

(MacOS) I got this issue after getting some malware that was forcing me to use WeKnow as a search engine. To fix this on MacOs I followed these steps

1. Go to System Preferences, then check if there's an icon named Profiles.

2. Remove AdminPrefs profile

3. Change default search engine settings, Restart Chrome

The above partially helped (I still had WeKnow as my home page). After that I followed these steps:

1. Type chrome://policy/ to see the policies. You cannot change them there

2. Copy paste this into your terminal

defaults write com.google.Chrome HomepageIsNewTabPage -bool false

defaults write com.google.Chrome NewTabPageLocation -string "https://www.google.com/"

defaults write com.google.Chrome HomepageLocation -string "https://www.google.com/"

defaults delete com.google.Chrome DefaultSearchProviderSearchURL

defaults delete com.google.Chrome DefaultSearchProviderNewTabURL

defaults delete com.google.Chrome DefaultSearchProviderName

I've also ran a scan of my system with Avast antivirus that has detected some malware

One the elements are added, use the rules method to add the rules

//bug fixed thanks to @Sparky
$('input[name^="fileupload"]').each(function () {
    $(this).rules('add', {
        required: true,
        accept: "image/jpeg, image/pjpeg"
    })
})

Demo: Fiddle

Update

var filenumber = 1;
$("#AddFile").click(function () { //User clicks button #AddFile
    var $li = $('<li><input type="file" name="FileUpload' + filenumber + '" id="FileUpload' + filenumber + '" required=""/> <a href="#" class="RemoveFileUpload">Remove</a></li>').prependTo("#FileUploader");

    $('#FileUpload' + filenumber).rules('add', {
        required: true,
        accept: "image/jpeg, image/pjpeg"
    })

    filenumber++;
    return false;
});

as amber and sinan have noted above, the javascritp '.split' method will work just fine. Just pass it the string separator(-) and the string that you intend to split('123-abc-itchy-knee') and it will do the rest.

    var coolVar = '123-abc-itchy-knee';
    var coolVarParts = coolVar.split('-'); // this is an array containing the items

    var1=coolVarParts[0]; //this will retrieve 123

To access each item from the array just use the respective index(indices start at zero).

• utf8 is MySQL's older, flawed implementation of UTF-8 which is in the process of being deprecated.
• utf8mb4 is what they named their fixed UTF-8 implementation, and is what you should use right now.

In their flawed version, only characters in the first 64k character plane - the basic multilingual plane - work, with other characters considered invalid. The code point values within that plane - 0 to 65535 (some of which are reserved for special reasons) can be represented by multi-byte encodings in UTF-8 of up to 3 bytes, and MySQL's early version of UTF-8 arbitrarily decided to set that as a limit. At no point was this limitation a correct interpretation of the UTF-8 rules, because at no point was UTF-8 defined as only allowing up to 3 bytes per character. In fact, the earliest definitions of UTF-8 defined it as having up to 6 bytes (since revised to 4). MySQL's original version was always arbitrarily crippled.

Back when MySQL released this, the consequences of this limitation weren't too bad as most Unicode characters were in that first plane. Since then, more and more newly defined character ranges have been added to Unicode with values outside that first plane. Unicode itself defines 17 planes, though so far only 7 of these are used.

In an effort not to break old code making any particular assumptions, MySQL retained the broken implementation and called the newer, fixed version utf8mb4. This has led to some confusion with the name being misinterpreted as if it's some kind of extension to UTF-8 or alternative form of UTF-8, rather than MySQL's implementation of the true UTF-8.

Future versions of MySQL will eventually phase out the older version, and for now it can be considered deprecated. For the foreseeable future you need to use utf8mb4 to ensure correct UTF-8 encoding. After sufficient time has passed, the current utf8 will be removed, and at some future date utf8 will rise again, this time referring to the fixed version, though utf8mb4 will continue to unambiguously refer to the fixed version.

Null means nothing. Its just a literal. Null is the value of reference variable. But empty string is blank.It gives the length=0. Empty string is a blank value,means the string does not have any thing.

Verify the following steps.

1. Did you include jquery
2. Check for errors in firebug

Those things should fix the problem

Do these steps:

1. open your MySQL configuration file: [drive]\xampp\mysql\bin\my.ini
2. look up for: # The MySQL server [mysqld]
3. add this right below it: lower_case_table_names = 2
4. save the file and restart MySQL service

As of the latest Bootstrap (3.1.x), the way to achieve a fluid layout it to use .container-fluid class.

See Bootstrap grid for reference

1with handler:

handler.sendEmptyMessageDelayed(1, 10000);
}

private Handler handler = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        if (msg.what == 1) {
           //your code
        }
    }
};

When you make a call to using namespace <some_namespace>; all symbols in that namespace will become visible without adding the namespace prefix. A symbol may be for instance a function, class or a variable.

E.g. if you add using namespace std; you can write just cout instead of std::cout when calling the operator cout defined in the namespace std.

This is somewhat dangerous because namespaces are meant to be used to avoid name collisions and by writing using namespace you spare some code, but loose this advantage. A better alternative is to use just specific symbols thus making them visible without the namespace prefix. Eg:

#include <iostream>
using std::cout;

int main() {
  cout << "Hello world!";
  return 0;
}

What if:

 <asp:Button ID="Button1" runat="server" CssClass="test1 test3 test-test" />

To add or remove a class, instead of overwriting all classes with

   BtnventCss.CssClass = "hom_but_a"

keep the HTML correct:

    string classname = "TestClass";

    // Add a class
    BtnventCss.CssClass = String.Join(" ", Button1
               .CssClass
               .Split(' ')
               .Except(new string[]{"",classname})
               .Concat(new string[]{classname})
               .ToArray()
       );

     // Remove a class
     BtnventCss.CssClass = String.Join(" ", Button1
               .CssClass
               .Split(' ')
               .Except(new string[]{"",classname})
               .ToArray()
       );

This assures

• The original classnames remain.
• There are no double classnames
• There are no disturbing extra spaces

Especially when client-side development is using several classnames on one element.

In your example, use

   string classname = "TestClass";

    // Add a class
    Button1.Attributes.Add("class", String.Join(" ", Button1
               .Attributes["class"]
               .Split(' ')
               .Except(new string[]{"",classname})
               .Concat(new string[]{classname})
               .ToArray()
       ));

     // Remove a class
     Button1.Attributes.Add("class", String.Join(" ", Button1
               .Attributes["class"]
               .Split(' ')
               .Except(new string[]{"",classname})
               .ToArray()
       ));

You should wrap this in a method/property ;)

The isinstance built-in is the preferred way if you really must, but even better is to remember Python's motto: "it's easier to ask forgiveness than permission"!-) (It was actually Grace Murray Hopper's favorite motto;-). I.e.:

def my_print(text, begin, end):
    "Print 'text' in UPPER between 'begin' and 'end' in lower"
    try:
      print begin.lower() + text.upper() + end.lower()
    except (AttributeError, TypeError):
      raise AssertionError('Input variables should be strings')

This, BTW, lets the function work just fine on Unicode strings -- without any extra effort!-)

You can't use a variable in an IN clause - you need to use dynamic SQL, or use a function (TSQL or CLR) to convert the list of values into a table.

Dynamic SQL example:

DECLARE @ExcludedList VARCHAR(MAX)
    SET @ExcludedList = 3 + ',' + 4 + ',' + '22'

DECLARE @SQL NVARCHAR(4000)
    SET @SQL = 'SELECT * FROM A WHERE Id NOT IN (@ExcludedList) '

 BEGIN

   EXEC sp_executesql @SQL '@ExcludedList VARCHAR(MAX)' @ExcludedList

 END

If it's just simple project, without cocoapods, like I had, u can try to move your framework inside your project directory and re-link. I had it on a desktop, but linked and "import MyFramework" made an error. After moving it inside project directory and linking it again, it worked.

This can now also happen in Node.js as of version 14.

It happens when you declare your package type as module in your package.json. If you do this, certain CommonJS variables can't be used, including require.

To fix this, remove "type": "module" from your package.json and make sure you don't have any files ending with .mjs.

The observer pattern is usually implemented with events.

Here's an example:

using System;

class Observable
{
    public event EventHandler SomethingHappened;

    public void DoSomething() =>
        SomethingHappened?.Invoke(this, EventArgs.Empty);
}

class Observer
{
    public void HandleEvent(object sender, EventArgs args)
    {
        Console.WriteLine("Something happened to " + sender);
    }
}

class Test
{
    static void Main()
    {
        Observable observable = new Observable();
        Observer observer = new Observer();
        observable.SomethingHappened += observer.HandleEvent;

        observable.DoSomething();
    }
}

See the linked article for a lot more detail.

Note that the above example uses C# 6 null-conditional operator to implement DoSomething safely to handle cases where SomethingHappened has not been subscribed to, and is therefore null. If you're using an older version of C#, you'd need code like this:

public void DoSomething()
{
    var handler = SomethingHappened;
    if (handler != null)
    {
        handler(this, EventArgs.Empty);
    }
}

Thought it might interesting to share that heroku does this with it's SSO to Add-on providers

An example of how it works can be seen in the source to the "kensa" tool:

https://github.com/heroku/kensa/blob/d4a56d50dcbebc2d26a4950081acda988937ee10/lib/heroku/kensa/post_proxy.rb

And can be seen in practice if you turn of javascript. Example page source:

<!DOCTYPE HTML>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>Heroku Add-ons SSO</title>
  </head>

  <body>
    <form method="POST" action="https://XXXXXXXX/sso/login">

        <input type="hidden" name="email" value="XXXXXXXX" />

        <input type="hidden" name="app" value="XXXXXXXXXX" />

        <input type="hidden" name="id" value="XXXXXXXX" />

        <input type="hidden" name="timestamp" value="1382728968" />

        <input type="hidden" name="token" value="XXXXXXX" />

        <input type="hidden" name="nav-data" value="XXXXXXXXX" />

    </form>

    <script type="text/javascript">
      document.forms[0].submit();
    </script>
  </body>
</html>

Try this:

mtcars %>%
  group_by(am, gear) %>%
  summarise(n = n()) %>%
  mutate(freq = n / sum(n))

#   am gear  n      freq
# 1  0    3 15 0.7894737
# 2  0    4  4 0.2105263
# 3  1    4  8 0.6153846
# 4  1    5  5 0.3846154

From the dplyr vignette:

When you group by multiple variables, each summary peels off one level of the grouping. That makes it easy to progressively roll-up a dataset.

Thus, after the summarise, the last grouping variable specified in group_by, 'gear', is peeled off. In the mutate step, the data is grouped by the remaining grouping variable(s), here 'am'. You may check grouping in each step with groups.

The outcome of the peeling is of course dependent of the order of the grouping variables in the group_by call. You may wish to do a subsequent group_by(am), to make your code more explicit.

For rounding and prettification, please refer to the nice answer by @Tyler Rinker.

win = new BrowserWindow({width: 1000, height: 1000,icon: __dirname + '/logo.png'}); //*.png or *.ico will also work 

in my case it worked !

In your example one and two are char pointers, pointing to char constants. You cannot change the char constants pointed to by these pointers. So anything like:

strcat(one,two); // append string two to string one.

will not work. Instead you should have a separate variable(char array) to hold the result. Something like this:

char result[100];   // array to hold the result.

strcpy(result,one); // copy string one into the result.
strcat(result,two); // append string two to the result.

If you use MSYS2...

Just install the certificate packages with the following commands:

32 bits

pacman -S mingw-w64-i686-ca-certificates ca-certificates

64 bits

pacman -S mingw-w64-x86_64-ca-certificates ca-certificates

If you don't want to clutter up your console with error messages, you can also run

git ls-files file_name

and then check the result. If git returns nothing, then the file is not tracked. If it's tracked, git will return the file path.

This comes in handy if you want to combine it in a script, for example PowerShell:

$gitResult = (git ls-files $_) | out-string
if ($gitResult.length -ne 0)
{
    ## do stuff with the tracked file
}

For MacOS this worked for me without the need to hardcode a particular Java version:

launchctl setenv JAVA_HOME "$(jenv javahome)"

You can sort the dataFrame by count and then remove duplicates. I think it's easier:

df.sort_values('count', ascending=False).drop_duplicates(['Sp','Mt'])

Google Brings me here. The favourite answers don't help me. I've now solved it, so maybe this will help someone else. Problem: after UPDATE of XAMPP to a new version I get the message "MySQL WILL NOT start without the configured ports free!".

However, I only have 1 instance of mysqld running.

It seems that the control panel is not as clever as it looks. As far as I can tell, the single instance of mysqld is the new one i've just updated to, but running as a 'service'. The control panel then tries to start it, and instead of realising its already running, It assumes its another service and reports the error.

Probable cause: The uninstaller failed to remove the autostart property from the mysql service, so the new instal picked it up.

Solution:
open the Xammpp Control Panel and click on the Services Button on the right. This will open the services control panel. Look for mysqld in the list of running processes, right-click it to get the properties and change the startup type to "Manual". you might as well do the same for Apache2 while you're here. Apply changes and Close the services control panel.

Now click the Config Button on xampp control panel, uncheck The Mysql (and Apache) Autostart features.

Reboot the machine. You should now be able to start / stop Mysql & Apache without any error messages. If this works, use the Xampp Control panel as usual to start/stop add service or add autostart as normal. No need to mess with any ports or config files.

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

Pay attention to one aspect when doing "purchase_date>(sysdate-30)": "sysdate" is the current date, hour, minute and second. So "sysdate-30" is not exactly "30 days ago", but "30 days ago at this exact hour".

If your purchase dates have 00.00.00 in hours, minutes, seconds, better doing:

where trunc(purchase_date)>trunc(sysdate-30)

(this doesn't take hours, minutes and seconds into account).

I'm using Conda on Windows and this answer did not work for me. But I can suggest another solution:

• rename enviroment folder (old_name to new_name)

• open shell and activate env with custom folder:

  conda.bat activate "C:\Users\USER_NAME\Miniconda3\envs\new_name"

• now you can use this enviroment, but it's not on the enviroment list. Update\install\remove any package to fix it. For example, update numpy:

  conda update numpy

• after applying any action to package, the environment will show in env list. To check this, type:

  conda env list

From what I understand, you have your data on a table and you want to create the CSV from that data. However, you have problem creating the CSV.

My thoughts would be to iterate and parse the contents of the table and generate a string from the parsed data. You can check How to convert JSON to CSV format and store in a variable for an example. You are using jQuery in your example so that would not count as an external plugin. Then, you just have to serve the resulting string using window.open and use application/octetstream as suggested.

Just copy and paste this code and you can experiment with two modals. Second modal is open after closing the first one:

                <button type="button" class="close" data-dismiss="modal">&times;</button>

        </div>
    </div>
</div>



<!-- The Modal 2 -->
<div class="modal" id="myModal2">
    <div class="modal-dialog">
        <div class="modal-content">

            <!-- Modal Header -->
            <div class="modal-header">

toCharArray followed by Arrays.sort followed by a String constructor call:

import java.util.Arrays;

public class Test
{
    public static void main(String[] args)
    {
        String original = "edcba";
        char[] chars = original.toCharArray();
        Arrays.sort(chars);
        String sorted = new String(chars);
        System.out.println(sorted);
    }
}

EDIT: As tackline points out, this will fail if the string contains surrogate pairs or indeed composite characters (accent + e as separate chars) etc. At that point it gets a lot harder... hopefully you don't need this :) In addition, this is just ordering by ordinal, without taking capitalisation, accents or anything else into account.

At the end of the last line, you have a new line character, which is not read by >> operator and it is not an end of file. Please, make an experiment and delete the new line (thelast character in file) - you will not get the duplication. To have a flexible code and avoid unwanted effects just apply any solution given by other users.

Okay, I'm not going to tell you a magical way of doing it because there isn't. If you have an action attribute set for a form element, it will redirect.

If you don't want it to redirect simply don't set any action and set onsubmit="someFunction();"

In your someFunction() you do whatever you want, (with AJAX or not) and in the ending, you add return false; to tell the browser not to submit the form...

Step-by-Step way to do this:

1. Install Android SDK
2. Start the emulator by going to $SDK_root/emulator.exe
3. Go to command prompt and go to the directory $SDK_root/platform-tools (or else add the path to windows environment)
4. Type in the command adb install
5. Bingo. Your app should be up and running on the emulator

You can do that with a psql slash command:

 \d myTable describe table

It also works for other objects:

 \d myView describe view
 \d myIndex describe index
 \d mySequence describe sequence

• Make Sure You Have MySQL Server Running
• Check connection with default credentials i.e. username : 'root' & password : '' [Blank Password]
• Try login phpmyadmin with same credentials
• Try to put 127.0.0.1 instead localhost or your lan IP would do too.
• Make sure you are running MySql on 3306 and if you have configured make sure to state it while making a connection

The problem for me was that I read the response twice as follows:

System.out.println(response.body().string());
getSucherResponse = objectMapper.readValue(response.body().string(), GetSucherResponse.class);

However, the response can only be read once as it is a stream.

I solved my problem like this

$('#startdatetime-from').datetimepicker({
language: 'en',
format: 'yyyy-MM-dd hh:mm',
defaultDate:new Date()

I was trying to measure the time between events with the exception of what one entry that has multiple processes between the start and end. I needed this in the context of other single line processes.

I used a select with an inner join as my select statement within the Nth cte. The second cte I needed to extract the start date on X and end date on Y and used 1 as an id value to left join to put them on a single line.

Works for me, hope this helps.

It will work perfectly when you will place the two required jar files under /WEB-INF/lib folder i.e. jstl-1.2.jar and javax.servlet.jsp under /WEB-INF/lib folder.

Hope it helps. :)

Circa 2019, using jquery, this can be accessed using $('#DOMId').data('typeId') where $('#DOMId') is the jquery selector for your span element.

I had the same challenge. When I collapsed some menus I had on the left of my web app, the datatable would not resize. Adding "autoWidth": false duirng initialization worked for me.

$('#dataTable').DataTable({'autoWidth':false, ...});

You're using the exec form of ENTRYPOINT. Unlike the shell form, the exec form does not invoke a command shell. This means that normal shell processing does not happen. For example, ENTRYPOINT [ "echo", "$HOME" ] will not do variable substitution on $HOME. If you want shell processing then either use the shell form or execute a shell directly, for example: ENTRYPOINT [ "sh", "-c", "echo $HOME" ].
When using the exec form and executing a shell directly, as in the case for the shell form, it is the shell that is doing the environment variable expansion, not docker.(from Dockerfile reference)

In your case, I would use shell form

ENTRYPOINT ./greeting --message "Hello, $ADDRESSEE\!"

Old question, I know. Disabling the cache facility is not needed and not the best way to manage the problem. By disabling the cache facility the server needs to work harder and generates more traffic. Also the browser and device needs to work harder, especially on mobile devices this could be a problem.

The empty page can be easily solved by using Shift key+reload button at the browser.

The empty page can be a result of:

• a bug in your code
• while testing you served an empty page (you can't remember) that is cached by the browser
• a bug in Safari (if so, please report it to Apple and don't try to fix it yourself)

Try first the Shift keyboard key + reload button and see if the problem still exists and review your code.

If you have the source code, you can use ndepend.

http://www.ndepend.com/

It's pricey and does a lot more than analyzing dependencies so it might be overkill for what you are looking for.

For this functionality you are better off not using a lock at all. Try an AtomicReference.

public class Sample {
    private final AtomicReference<String> msg = new AtomicReference<String>();

    public void setMsg(String x) {
        msg.set(x);
    }

    public String getMsg() {
        return msg.getAndSet(null);
    }
}

No locks required and the code is simpler IMHO. In any case, it uses a standard construct which does what you want.

The idea ...To create a File object (api) in javaScript for images already present in the DOM :

<img src="../img/Products/fijRKjhudDjiokDhg1524164151.jpg">

var file = new File(['fijRKjhudDjiokDhg1524164151'],
                     '../img/Products/fijRKjhudDjiokDhg1524164151.jpg', 
                     {type:'image/jpg'});

// created object file
console.log(file);

Don't do that ! ... (but I did it anyway)

-> the console give a result similar as an Object File :

File(0) {name: "fijRKjokDhgfsKtG1527053050.jpg", lastModified: 1527053530715, lastModifiedDate: Wed May 23 2018 07:32:10 GMT+0200 (Paris, Madrid (heure d’été)), webkitRelativePath: "", size: 0, …}
lastModified:1527053530715
lastModifiedDate:Wed May 23 2018 07:32:10 GMT+0200 (Paris, Madrid (heure d’été)) {}
name:"fijRKjokDhgfsKtG1527053050.jpg"
size:0
type:"image/jpg"
webkitRelativePath:""__proto__:File

But the size of the object is wrong ...

Why i need to do that ?

For example to retransmit an image form already uploaded, during a product update, along with additional images added during the update

In Android Lollipop and above, define it in your theme style:

<style name="BaseAppTheme" parent="Material.Theme">
    ...
    <item name="android:colorControlActivated">@color/color_switch</item>
</style>

1. The best getters / setters are smart.

Here's a javascript example from mozilla:

var o = { a:0 } // `o` is now a basic object

Object.defineProperty(o, "b", { 
    get: function () { 
        return this.a + 1; 
    } 
});

console.log(o.b) // Runs the getter, which yields a + 1 (which is 1)

I've used these A LOT because they are awesome. I would use it when getting fancy with my coding + animation. For example, make a setter that deals with an Number which displays that number on your webpage. When the setter is used it animates the old number to the new number using a tweener. If the initial number is 0 and you set it to 10 then you would see the numbers flip quickly from 0 to 10 over, let's say, half a second. Users love this stuff and it's fun to create.

2. Getters / setters in php

Example from sof

<?php
class MyClass {
  private $firstField;
  private $secondField;

  public function __get($property) {
    if (property_exists($this, $property)) {
      return $this->$property;
    }
  }

  public function __set($property, $value) {
    if (property_exists($this, $property)) {
      $this->$property = $value;
    }

    return $this;
  }
}
?>

citings:

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/get
• http://tweener.ivank.net/
• Getter and Setter?

Using Extension Methods:

public static class ObjectExtension
{
    public static bool In(this object obj, params object[] objects)
    {
        if (objects == null || obj == null)
            return false;
        object found = objects.FirstOrDefault(o => o.GetType().Equals(obj.GetType()) && o.Equals(obj));
        return (found != null);
    }
}

Now you can do this:

string role= "Admin";
if (role.In("Admin", "Director"))
{ 
    ...
} 

__construct() is the method name for the constructor. The constructor is called on an object after it has been created, and is a good place to put initialisation code, etc.

class Person {

    public function __construct() {
        // Code called for each new Person we create
    }

}

$person = new Person();

A constructor can accept parameters in the normal manner, which are passed when the object is created, e.g.

class Person {

    public $name = '';

    public function __construct( $name ) {
        $this->name = $name;
    }

}

$person = new Person( "Joe" );
echo $person->name;

Unlike some other languages (e.g. Java), PHP doesn't support overloading the constructor (that is, having multiple constructors which accept different parameters). You can achieve this effect using static methods.

Note: I retrieved this from the log of the (at time of this writing) accepted answer.

yes, its possible, run this command:

lets say you have user called thoko

grant select any table, insert any table, delete any table, update any table to thoko;

note: worked on oracle database

@Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)

Given annotation worked for me. Can have a try

For Example :-

     public class Parent{
            @Id
            @GeneratedValue(strategy=GenerationType.AUTO)
            @Column(name="cct_id")
            private Integer cct_id;
            @OneToMany(cascade=CascadeType.REMOVE, fetch=FetchType.EAGER,mappedBy="clinicalCareTeam", orphanRemoval=true)
            @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
            private List<Child> childs;
        }
            public class Child{
            @ManyToOne(fetch=FetchType.EAGER)
            @JoinColumn(name="cct_id")
            private Parent parent;
    }

git config credential.helper store

Note: While this is convenient, Git will store your credentials in clear text in a local file (.git-credentials) under your project directory (see below for the "home" directory). If you don't like this, delete this file and switch to using the cache option.

If you want Git to resume to asking you for credentials every time it needs to connect to the remote repository, you can run this command:

git config --unset credential.helper

To store the passwords in .git-credentials in your %HOME% directory as opposed to the project directory: use the --global flag

git config --global credential.helper store

You have to replace string line

QString line = in.readLine();

into while:

QFile file("/home/hamad/lesson11.txt");
if(!file.open(QIODevice::ReadOnly)) {
    QMessageBox::information(0, "error", file.errorString());
}

QTextStream in(&file);

while(!in.atEnd()) {
    QString line = in.readLine();    
    QStringList fields = line.split(",");    
    model->appendRow(fields);    
}

file.close();

As Suhel Meman said in the comments:

SELECT column1, column2, column3 FROM table 1
UNION
SELECT column1, column2, column3 FROM table 2
...

would work.

But all your SELECTS would have to consist of the same amount of columns. And because you are displaying it in one resulting table they should contain the same information.

What you might want to do, is a JOIN on Product ID or something like that. This way you would get more columns, which makes more sense most of the time.

update @Marcel Jackwerth's answer for general.

and only working with class attribute, not working with method variable.

    /**
     * get variable name as string
     * only work with class attributes
     * not work with method variable
     *
     * @param headClass variable name space
     * @param vars      object variable
     * @throws IllegalAccessException
     */
    public static void printFieldNames(Object headClass, Object... vars) throws IllegalAccessException {
        List<Object> fooList = Arrays.asList(vars);
        for (Field field : headClass.getClass().getFields()) {
            if (fooList.contains(field.get(headClass))) {
                System.out.println(field.getGenericType() + " " + field.getName() + " = " + field.get(headClass));
            }
        }
    }

Also you can use faster_than_requests package. That's very fast and simple:

import faster_than_requests as r
content = r.get2str("http://test.com/")

Look at this comparison:

Try the following:

if ((select VisitCount from PageImage where PID=@pid and PageNumber=5) is NULL)
begin
    update PageImage
    set VisitCount=1
    where PID=@pid and PageNumber=@pageno
end 
else
begin
    update PageImage 
    set VisitCount=VisitCount+1
    where PID=@pid and PageNumber=@pageno
end

I had to edit the below file on my Ubuntu 18.04:

/etc/mysql/mysql.conf.d/mysqld.cnf

with

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

and

sudo service mysql restart

If you need binary mode, you'll need to do it the hard way:

s = File.open(filename, 'rb') { |f| f.read }

If not, shorter and sweeter is:

s = IO.read(filename)

e.which doesn't work in IE try e.keyCode, also you probably want to use keydown() instead of keypress() if you are targeting IE.

See http://unixpapa.com/js/key.html for more information.

//create a variable that contain your button
Button button = (Button) findViewById(R.id.button);

    button.setOnClickListener(new OnClickListener(){
        @Override
        //On click function
        public void onClick(View view) {
            //Create the intent to start another activity
            Intent intent = new Intent(view.getContext(), AnotherActivity.class);
            startActivity(intent);
        }
    });

Closing all files and closing Android Studio works for me.

You need to multiply your Model matrix. Because that is where model position, scaling and rotation should be (that's why it's called the model matrix).

All you need to do is (see here)

Model = glm::rotate(Model, angle_in_radians, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)

Note that to convert from degrees to radians, use glm::radians(degrees)

That takes the Model matrix and applies rotation on top of all the operations that are already in there. The other functions translate and scale do the same. That way it's possible to combine many transformations in a single matrix.

note: earlier versions accepted angles in degrees. This is deprecated since 0.9.6

Model = glm::rotate(Model, angle_in_degrees, glm::vec3(x, y, z)); // where x, y, z is axis of rotation (e.g. 0 1 0)

Besides using multiple proxies or proxy-networks, you might want to try the planet-lab. (And probably there are other similar institutions around).

The social solution would be to post a question on some board that you are searching for volunteers that proxy your requests. (They only have to allow for one destination in their proxy config thus the danger of becoming spam-whores is relatively low.) You should prepare credentials that ensure your partners of the authenticity of the claim that the destination is indeed your computer.

Other answers are great, I just want to add... a different approach usable in PowerShell: Install GNUWin32 utils and use grep to view the lines / redirect the output to file http://gnuwin32.sourceforge.net/

This overwrites the new file every time:

grep "step[49]" logIn.log > logOut.log 

This appends the log output, in case you overwrite the logIn file and want to keep the data:

grep "step[49]" logIn.log >> logOut.log 

Note: to be able to use GNUWin32 utils globally you have to add the bin folder to your system path.

I got this error, hope this will help someone:

const firstName = 'Joe';
const lastName = 'Blogs';
const wholeName = firstName + ' ' lastName + '.';

The problem was that I was missing a plus (+) between the empty space and lastName. This is a super simplified example: I was concatenating about 9 different parts so it was hard to spot the error.

Summa summarum: if you get "SyntaxError: missing ; before statement", don't look at what is wrong with the the semicolon (;) symbols in your code, look for an error in syntax on that line.

You can use:

$redirectURL = curl_getinfo($ch,CURLINFO_REDIRECT_URL);

For me I copied my fonts folder from the assets to the res folder and caused the problem because Android Studio didn't accept capitalized names. I switched to project view mode and deleted it then added it as font resource file by right clicking res folder.

All you need to do is

android:isScrollContainer="true"

Sqlldr wants to write a log file in the same directory where the control file is. But obviously it can't. It probably doesn't have the required permission.

If you're on Linux or Unix, try to run the following command the same way you run sqldr:

touch Billing.log

It will show whether you have the permissions.

Update

The proper command line is:

sqlldr myusername/mypassword control=Billing.ctl

To say that something "is null" means that it is a reference to the null value. Primitives (int, double, float, etc) are by definition not reference types, so they cannot have null values. You will need to find out what your database wrapper will do in this case.

What about this?

std::sort(numbers.begin(), numbers.end());
std::reverse(numbers.begin(), numbers.end());

I got confused by the answer to this question, so I created a test case in MySQL, hope this helps

I found a solution wich is to do:

<span class="visible-sm"> your code without col </span>
<span class="visible-xs"> your code with col </span>

It's not very optimized but it works. Did you find something better? It really miss a class like col-sm-0 to apply colons just to the xs size...

Not sure if there any disadvantages to this approach but even more minimal, in views.py:

entry = form.save()

# save uploaded file
if request.FILES['myfile']:
    entry.myfile.save(request.FILES['myfile']._name, request.FILES['myfile'], True)

I was always under the impression the rule came from the days when parsing a file without an ending newline was difficult. That is, you would end up writing code where an end of line was defined by the EOL character or EOF. It was just simpler to assume a line ended with EOL.

However I believe the rule is derived from C compilers requiring the newline. And as pointed out on “No newline at end of file” compiler warning, #include will not add a newline.

An inline div is a freak of the web & should be beaten until it becomes a span (at least 9 times out of 10)...

<span>foo</span>
<span>bar</span>
<span>baz</span>

...answers the original question...

I have just copied and moved a Magento site to a local area so I could work on it offline and had the same problem.

But in the end I found out Magento was forcing a redirect from http to https and I didn't have a SSL setup. So this solved my problem http://www.magentocommerce.com/wiki/recover/ssl_access_with_phpmyadmin

It pretty much says set web/secure/use_in_adminhtml value from 1 to 0 in the core_config_data to allow non-secure access to the admin area

With regard to bootstrap, the correct answer is using spacing utilities as mentioned by loopasam in a previous comment. Following is an example of using padding for both left and right.

<a href="#" class="nav-item nav-link px-3">Blog</a>

leftclickben answer worked for me, but I wanted a path from a given node back up the tree to the root, and these seemed to be going the other way, down the tree. So, I had to flip some of the fields around and renamed for clarity, and this works for me, in case this is what anyone else wants too--

item | parent
-------------
1    | null
2    | 1
3    | 1
4    | 2
5    | 4
6    | 3

and

select t.item_id as item, @pv:=t.parent as parent
from (select * from item_tree order by item_id desc) t
join
(select @pv:=6)tmp
where t.item_id=@pv;

gives:

item | parent
-------------
6    | 3
3    | 1
1    | null

Array initializer support for type inference were changed in Visual Basic 10 vs Visual Basic 9.

In previous version of VB it was required to put empty parens to signify an array. Also, it would define the array as object array unless otherwise was stated:

' Integer array
Dim i as Integer() = {1, 2, 3, 4} 

' Object array
Dim o() = {1, 2, 3}

It seems you need to do some configuring as you seem to be using SSL; here's a step-by-step guide by Scott Hanselman himself.

Using event.target.reset() only works for uncontrolled components, which is not recommended. For controlled components you would do something like this:

import React, { Component } from 'react'

class MyForm extends Component {
  initialState = { name: '' }

  state = this.initialState

  handleFormReset = () => {
    this.setState(() => this.initialState)
  }

  render() {

    return (
      <form onReset={this.handleFormReset}>
        <div>
          <label htmlFor="name">Name</label>
          <input
            type="text"
            placeholder="Enter name"
            name="name"
            value={name}
            onChange={this.handleInputOnChange}
          />
        </div>
        <div>
          <input
            type="submit"
            value="Submit"
          />
          <input
            type="reset"
            value="Reset"
          />
        </div>
      </form>
    )
  }
}

ContactAdd.propTypes = {}

export default MyForm

There's certainly a performance difference when running a compiled script. If you run normal .py scripts, the machine compiles it every time it is run and this takes time. On modern machines this is hardly noticeable but as the script grows it may become more of an issue.

Cross Join: http://www.dba-oracle.com/t_garmany_9_sql_cross_join.htm

TLDR; Generates a all possible combinations between 2 tables (Carthesian product)

(Full) Outer Join: http://www.w3schools.com/Sql/sql_join_full.asp

TLDR; Returns every row in both tables and also results that have the same values (matches in CONDITION)

Maybe try simply

@(Model.AuditDate.HasValue ? Model.AuditDate.ToString("mm/dd/yyyy") : String.Empty)

also you can use many type of string format like .ToString("dd MMM, yyyy") .ToString("d") etc

Try this one in your css document,

-fx-background-color : #ffaadd;

or

-fx-base : #ffaadd; 

Also, you can set background color on your object with this code directly.

yourPane.setBackground(new Background(new BackgroundFill(Color.DARKGREEN, CornerRadii.EMPTY, Insets.EMPTY)));

You can determine if as certain word is found in a cell by using

If InStr(cell.Value, "Word1") > 0 Then

If Word1 is found in the string the InStr() function will return the location of the first character of Word1 in the string.

I know this is old, but for those surfing this question, the answer by MUG4N will align all columns that use the same defaultcellstyle. I'm not using autogeneratecolumns so that is not acceptable. Instead I used:

e.Column.DefaultCellStyle = new DataGridViewCellStyle(e.Column.DefaultCellStyle);
e.Column.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleRight;

In this case e is from:

Grd_ColumnAdded(object sender, DataGridViewColumnEventArgs e)  

According to Django documentation, inline formsets are for this purpose: "Inline formsets is a small abstraction layer on top of model formsets. These simplify the case of working with related objects via a foreign key".

See https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#inline-formsets

Many ways to skin the cat here and @Mitch's suggestion is a good way. If you want the client form to have more 'control', you may want to pass the instance of the parent to the child when created and then you can call any public parent method on the child.

Don't write if statements without a corresponding else. Once you add the else to your fragment you'll see that your true and false are in fact the last expressions of the function.

def balanceMain(elem: List[Char]): Boolean =

    else
      if (elem.head == '(')

I think you may have over-complicated your code: If you are just checking to see if a service is running and, if not, run it and then stop re-evaluating, the following should suffice:

Good point on the refresh.

$ServiceName = 'Serenade'
$arrService = Get-Service -Name $ServiceName

while ($arrService.Status -ne 'Running')
{

    Start-Service $ServiceName
    write-host $arrService.status
    write-host 'Service starting'
    Start-Sleep -seconds 60
    $arrService.Refresh()
    if ($arrService.Status -eq 'Running')
    {
        Write-Host 'Service is now Running'
    }

}

If you don't want to use the url helper, you can get the same results by using the following variable:

$this->config->config['base_url']

It will return the base url for you with no extra steps required.

Let us assume the database character set is UTF-8, which is the recommended setting in recent versions of Oracle. In this case, some characters take more than 1 byte to store in the database.

If you define the field as VARCHAR2(11 BYTE), Oracle can use up to 11 bytes for storage, but you may not actually be able to store 11 characters in the field, because some of them take more than one byte to store, e.g. non-English characters.

By defining the field as VARCHAR2(11 CHAR) you tell Oracle it can use enough space to store 11 characters, no matter how many bytes it takes to store each one. A single character may require up to 4 bytes.

You must be separate those classes which you want to remove by white space$('selector').removeClass('class1 class2');

You can use attrchange jQuery plugin. The main function of the plugin is to bind a listener function on attribute change of HTML elements.

Code sample:

$("#myDiv").attrchange({
    trackValues: true, // set to true so that the event object is updated with old & new values
    callback: function(evnt) {
        if(evnt.attributeName == "display") { // which attribute you want to watch for changes
            if(evnt.newValue.search(/inline/i) == -1) {

                // your code to execute goes here...
            }
        }
    }
});

@Table's name attribute is the actual table name. @Entitiy's name is useful if you have two @Entity classes with the same name and you need a way to differentiate them when running queries.

In bootstrap 4 use:

This will push the navbar to the right. Use mr-auto to push it to the left, this is the default behaviour.

Algorithm

Scrolling an element requires changing its scrollTop value over time. For a given point in time, calculate a new scrollTop value. To animate smoothly, interpolate using a smooth-step algorithm.

Calculate scrollTop as follows:

var point = smooth_step(start_time, end_time, now);
var scrollTop = Math.round(start_top + (distance * point));

Where:

• start_time is the time the animation started;
• end_time is when the animation will end (start_time + duration);
• start_top is the scrollTop value at the beginning; and
• distance is the difference between the desired end value and the start value (target - start_top).

A robust solution should detect when animating is interrupted, and more. Read my post about Smooth Scrolling without jQuery for details.

Demo

See the JSFiddle.

Implementation

The code:

/**
    Smoothly scroll element to the given target (element.scrollTop)
    for the given duration

    Returns a promise that's fulfilled when done, or rejected if
    interrupted
 */
var smooth_scroll_to = function(element, target, duration) {
    target = Math.round(target);
    duration = Math.round(duration);
    if (duration < 0) {
        return Promise.reject("bad duration");
    }
    if (duration === 0) {
        element.scrollTop = target;
        return Promise.resolve();
    }

    var start_time = Date.now();
    var end_time = start_time + duration;

    var start_top = element.scrollTop;
    var distance = target - start_top;

    // based on http://en.wikipedia.org/wiki/Smoothstep
    var smooth_step = function(start, end, point) {
        if(point <= start) { return 0; }
        if(point >= end) { return 1; }
        var x = (point - start) / (end - start); // interpolation
        return x*x*(3 - 2*x);
    }

    return new Promise(function(resolve, reject) {
        // This is to keep track of where the element's scrollTop is
        // supposed to be, based on what we're doing
        var previous_top = element.scrollTop;

        // This is like a think function from a game loop
        var scroll_frame = function() {
            if(element.scrollTop != previous_top) {
                reject("interrupted");
                return;
            }

            // set the scrollTop for this frame
            var now = Date.now();
            var point = smooth_step(start_time, end_time, now);
            var frameTop = Math.round(start_top + (distance * point));
            element.scrollTop = frameTop;

            // check if we're done!
            if(now >= end_time) {
                resolve();
                return;
            }

            // If we were supposed to scroll but didn't, then we
            // probably hit the limit, so consider it done; not
            // interrupted.
            if(element.scrollTop === previous_top
                && element.scrollTop !== frameTop) {
                resolve();
                return;
            }
            previous_top = element.scrollTop;

            // schedule next frame for execution
            setTimeout(scroll_frame, 0);
        }

        // boostrap the animation process
        setTimeout(scroll_frame, 0);
    });
}

If you are aiming for maximum browser support, modern approach is to place button in a div with display:flex; and flex-direction:row; The same trick will work for height with flex-direction:column; or both height and width(will require 2 divs)

The application I'm working on has to give the user the possibility to choose which fragments to display (fragments are dynamically changed at run-time). The best solution for me was to restart completely the application.

So I tried plenty of solutions and none of them has worked for me, but this:

final Intent mStartActivity = new Intent(SettingsActivity.this, Splash.class);
final int mPendingIntentId = 123456;
final PendingIntent mPendingIntent = PendingIntent.getActivity(SettingsActivity.this, mPendingIntentId, mStartActivity,
                    PendingIntent.FLAG_CANCEL_CURRENT);
final AlarmManager mgr = (AlarmManager) SettingsActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
this.finishAffinity(); //notice here
Runtime.getRuntime().exit(0); //notice here

Hoping that is going to help someone else!

The --no-ff option is useful when you want to have a clear notion of your feature branch. So even if in the meantime no commits were made, FF is possible - you still want sometimes to have each commit in the mainline correspond to one feature. So you treat a feature branch with a bunch of commits as a single unit, and merge them as a single unit. It is clear from your history when you do feature branch merging with --no-ff.

If you do not care about such thing - you could probably get away with FF whenever it is possible. Thus you will have more svn-like feeling of workflow.

For example, the author of this article thinks that --no-ff option should be default and his reasoning is close to that I outlined above:

Consider the situation where a series of minor commits on the "feature" branch collectively make up one new feature: If you just do "git merge feature_branch" without --no-ff, "it is impossible to see from the Git history which of the commit objects together have implemented a feature—you would have to manually read all the log messages. Reverting a whole feature (i.e. a group of commits), is a true headache [if --no-ff is not used], whereas it is easily done if the --no-ff flag was used [because it's just one commit]."

This is the extension I use for calculating multiline UILabel heights, it's an adjusted snippet from a previous stack overflow post:

extension UILabel {
    func estimatedHeight(forWidth: CGFloat, text: String, ofSize: CGFloat) -> CGFloat {

        let size = CGSize(width: forWidth, height: CGFloat(MAXFLOAT))

        let options = NSStringDrawingOptions.usesFontLeading.union(.usesLineFragmentOrigin)

        let attributes = [NSFontAttributeName: UIFont.systemFont(ofSize: ofSize)]

        let rectangleHeight = String(text).boundingRect(with: size, options: options, attributes: attributes, context: nil).height

        return ceil(rectangleHeight)
    }
}

If you need to do it manually, one time:

First, merge in a temporary table, with something like:

create table MERGED as select * from table 1 UNION select * from table 2

Then, identify the primary key constraints with something like

SELECT COUNT(*), PK from MERGED GROUP BY PK HAVING COUNT(*) > 1

Where PK is the primary key field...

Solve the duplicates.

Rename the table.

[edited - removed brackets in the UNION query, which was causing the error in the comment below]

See example here: Input and Output binary streams using JERSEY?

Pseudo code would be something like this (there are a few other similar options in above mentioned post):

@Path("file/")
@GET
@Produces({"application/pdf"})
public StreamingOutput getFileContent() throws Exception {
     public void write(OutputStream output) throws IOException, WebApplicationException {
        try {
          //
          // 1. Get Stream to file from first server
          //
          while(<read stream from first server>) {
              output.write(<bytes read from first server>)
          }
        } catch (Exception e) {
            throw new WebApplicationException(e);
        } finally {
              // close input stream
        }
    }
}

This code worked for me

public static void main(String[] args) {
    try {
        java.net.URL myUr = new java.net.URL("http://path");
        System.out.println("Instantiated new URL: " + connection_url);
    }
    catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

Instantiated new URL: http://path

Java 8:

int[] intArr = Arrays.stream(integerList).mapToInt(i->i).toArray();

If one wants to get the line count cheaply in Python in Linux, I recommend this method:

import os
print os.popen("wc -l file_path").readline().split()[0]

file_path can be both abstract file path or relative path. Hope this may help.

to wait until the click itself is complete (ie to resolve the Promise), use await keyword

it('test case 1', async () => {
  await login.submit.click();
})

This will stop the command queue until the click (sendKeys, sleep or any other command) is finished

If you're lucky and you're on angular page that is built well and doesn't have micro and macro tasks pending then Protractor should wait by itself until the page is ready. But sometimes you need to handle waiting yourself, for example when logging in through a page that is not Angular (read how to find out if page has pending tasks and how to work with non angular pages)

In the case you're handling the waiting manually, browser.wait is the way to go. Just pass a function to it that would have a condition which to wait for. For example wait until there is no loading animation on the page

let $animation = $$('.loading');

await browser.wait(
  async () => (await animation.count()) === 0, // function; if returns true it stops waiting; can wait for anything in the world if you get creative with it
  5000, // timeout
  `message on timeout`
);

Make sure to use await

I don't believe this is possible. I believe you have to clone that remote repo locally and perform git fetch on it before you can issue a git log against it.

This is the solution via multiple replace, which works for any strings (does not need special characters, which are not part of the string).

declare @value varchar(max)
declare @result varchar(max)
set @value = 'alpha   beta gamma  delta       xyz'

set @result = replace(replace(replace(replace(replace(replace(replace(
  @value,'a','ac'),'x','ab'),'  ',' x'),'x ',''),'x',''),'ab','x'),'ac','a')

select @result -- 'alpha beta gamma delta xyz'

Some optimizations:

• save the NodeList's length in a variable
• explicitly set the new array's length before setting.
• access the indices, rather than pushing or unshifting.

Code (jsPerf):

var arr = [];
for (var i = 0, ref = arr.length = nl.length; i < ref; i++) {
 arr[i] = nl[i];
}

How about using a public Event

I would do it like this.

public class Form2
{
   public event Action<string> SomethingCompleted;

   private void Submit_Click(object sender, EventArgs e)
   {
       SomethingCompleted?.Invoke(txtData.Text);
       this.Close();
   }
}

and call it from Form1 like this.

private void btnOpenForm2_Click(object sender, EventArgs e)
{
    using (var frm = new Form2())
    {
        frm.SomethingCompleted += text => {
            this.txtData.Text = text;
        };

        frm.ShowDialog();
    }
}

Then, Form1 could get a text from Form2 when Form2 is closed

Thank you.

You have given permission to perform commands on objects inside the S3 bucket, but you have not given permission to perform any actions on the bucket itself.

Slightly modifying your policy would look like this:

{
  "Version": "version_id",
  "Statement": [
    {
        "Sid": "some_id",
        "Effect": "Allow",
        "Action": [
            "s3:*"
        ],
        "Resource": [
            "arn:aws:s3:::bucketname",
            "arn:aws:s3:::bucketname/*"
        ]
    }
  ] 
}

However, that probably gives more permission than is needed. Following the AWS IAM best practice of Granting Least Privilege would look something like this:

{
  "Version": "2012-10-17",
  "Statement": [
      {
          "Effect": "Allow",
          "Action": [
              "s3:ListBucket"
          ],
          "Resource": [
              "arn:aws:s3:::bucketname"
          ]
      },
      {
          "Effect": "Allow",
          "Action": [
              "s3:GetObject"
          ],
          "Resource": [
              "arn:aws:s3:::bucketname/*"
          ]
      }
  ]
}

I just came across this problem and have written a solution for those of you who are using Angular. You can write a custom directive composed of a container, a button, and an input element with type file. With CSS you then place the input over the custom button but with opacity 0. You set the containers height and width to exactly the offset width and height of the button and the input's height and width to 100% of the container.

the directive

angular.module('myCoolApp')
  .directive('fileButton', function () {
    return {
      templateUrl: 'components/directives/fileButton/fileButton.html',
      restrict: 'E',
      link: function (scope, element, attributes) {

        var container = angular.element('.file-upload-container');
        var button = angular.element('.file-upload-button');

        container.css({
            position: 'relative',
            overflow: 'hidden',
            width: button.offsetWidth,
            height: button.offsetHeight
        })

      }

    };
  });

a jade template if you are using jade

div(class="file-upload-container") 
    button(class="file-upload-button") +
    input#file-upload(class="file-upload-input", type='file', onchange="doSomethingWhenFileIsSelected()")  

the same template in html if you are using html

<div class="file-upload-container">
   <button class="file-upload-button"></button>
   <input class="file-upload-input" id="file-upload" type="file" onchange="doSomethingWhenFileIsSelected()" /> 
</div>

the css

.file-upload-button {
    margin-top: 40px;
    padding: 30px;
    border: 1px solid black;
    height: 100px;
    width: 100px;
    background: transparent;
    font-size: 66px;
    padding-top: 0px;
    border-radius: 5px;
    border: 2px solid rgb(255, 228, 0); 
    color: rgb(255, 228, 0);
}

.file-upload-input {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 2;
    width: 100%;
    height: 100%;
    opacity: 0;
    cursor: pointer;
}

You should change source code Language Level also on the Source tab (Modules part).

if you're turned off by the extra line, you can use a wrapper function like so:

def with_iter(iterable):
    with iterable as iter:
        for item in iter:
            yield item

for line in with_iter(open('...')):
    ...

in Python 3.3, the yield from statement would make this even shorter:

def with_iter(iterable):
    with iterable as iter:
        yield from iter

If you a running Jupyter/Ipython notebook and having problems using;

ax = df1.plot()

df2.plot(ax=ax)

Run the command inside of the same cell!! It wont, for some reason, work when they are separated into sequential cells. For me at least.

I had a similar problem and it was due to singlequotes. The JSON standard(http://json.org) talks only about using double quotes so it must be that the python json library supports only double quotes.

You can always use normal functions:

function myPrivateFunction() {
  console.log("My property: " + this.prop);
}

class MyClass() {
  constructor() {
    this.prop = "myProp";
    myPrivateFunction.bind(this)();
  }
}

new MyClass(); // 'My property: myProp'

See if this answer can help you. Particularly the fact that CLI ini could be different than when the script is running through a browser.

Allowed memory size of X bytes exhausted

$string = str_replace(array("\n", "\r"), ' ', $string);

use
if in vim:

:s/{\|}/"/g

will replace { and } on " so {lol} becomes "lol"

In the simplest terms, a Turing-complete system can solve any possible computational problem.

One of the key requirements is the scratchpad size be unbounded and that is possible to rewind to access prior writes to the scratchpad.

Thus in practice no system is Turing-complete.

Rather some systems approximate Turing-completeness by modeling unbounded memory and performing any possible computation that can fit within the system's memory.

If someone wants to do the same thing with Pandas

import pandas as pd
import sqlite3
conn = sqlite3.connect("db.sqlite3")
table = pd.read_sql_query("SELECT name FROM sqlite_master WHERE type='table'", conn)
print(table)

Let's say we have an external table called employee

hive> SHOW CREATE TABLE employee;
OK
CREATE EXTERNAL TABLE employee(
  id string,
  fname string,
  lname string, 
  salary double)
ROW FORMAT SERDE
  'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
WITH SERDEPROPERTIES (
  'colelction.delim'=':',
  'field.delim'=',',
  'line.delim'='\n',
  'serialization.format'=',')
STORED AS INPUTFORMAT
  'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'

TBLPROPERTIES (

  'numFiles'='0',
  'numRows'='-1',
  'rawDataSize'='-1',
  'totalSize'='0',
  'transient_lastDdlTime'='1487884795')

1. To create a person table like employee

   CREATE TABLE person LIKE employee;

2. To create a person external table like employee

   CREATE TABLE person LIKE employee LOCATION 'maprfs:/user/hadoop/data/person';

3. then use DESC person; to see the newly created table schema.

JQuery has a way to pass parameters from HTML to javascript:

Put this in the myhtml.html file:

<!-- Import javascript -->
<script src="//code.jquery.com/jquery-1.11.2.min.js"></script>
<!-- Invoke a different javascript file called subscript.js -->
<script id="myscript" src="subscript.js" video_filename="foobar.mp4">/script>

In the same directory make a subscript.js file and put this in there:

//Use jquery to look up the tag with the id of 'myscript' above.  Get 
//the attribute called video_filename, stuff it into variable filename.
var filename = $('#myscript').attr("video_filename");

//print filename out to screen.
document.write(filename);

Analyze Result:

Loading the myhtml.html page has 'foobar.mp4' print to screen. The variable called video_filename was passed from html to javascript. Javascript printed it to screen, and it appeared as embedded into the html in the parent.

jsfiddle proof that the above works:

Apple recommends for stylistic purposes.If you write this code:

@property (nonatomic,assign) BOOL working;

Then you can not use [object isWorking].
It will show an error. But if you use below code means

@property (assign,getter=isWorking) BOOL working;

So you can use [object isWorking] .

Nothing worked for me except running a subprocess with this command, before calling HTTPServer(('', 443), myHandler):

kill -9 $(lsof -ti tcp:443)

Of course this is only for linux-like OS!

Run java with -d64 or -d32 specified, it will give you an error message if it doesn't support 64-bit or 32-bit respectively. Your JVM may support both.

You can if your processor is 64-bit and Virtualization Technology (VT) extension is enabled (it can be switched off in BIOS). You can't do it on 32-bit processor.

To check this under Linux you just need to look into /proc/cpuinfo file. Just look for the appropriate flag (vmx for Intel processor or svm for AMD processor)

egrep '(vmx|svm)' /proc/cpuinfo

To check this under Windows you need to use a program like CPU-Z which will display your processor architecture and supported extensions.

First get the container ID:

docker ps

(First column is for container ID)

Use the container ID to run:

docker inspect <container ID>

At the bottom,under "NetworkSettings", you can find "IPAddress"

Or Just do:

docker inspect <container id> | grep "IPAddress"

Autoplay doesn't work on the iPad or iPhone for either the video or the audio tags. This is a restriction set in place by Apple to save the users bandwidth.

I went threw the same problem. None of the answers above worked for me, but i ended finding the solution on my own. The ipa file wasn't created because there was library files (libXXX.a) in Target-> Build Phases -> Copy Bundle with resources

Hope it will help someone :)

In a Firebird database the AFTER myOtherColumn does not work but you can try re-positioning the column using:

ALTER TABLE name ALTER column POSITION new_position

I guess it may work in other cases as well.

=SUMPRODUCT((A1:A5="FRANCE")*B1:D5)

You can use strcpy but remember to end the array with '\0'

char array[20]; char string[100];

array[0]='1'; array[1]='7'; array[2]='8'; array[3]='.'; array[4]='9'; array[5]='\0';
strcpy(string, array);
printf("%s\n", string);

Use .ignore plugin: https://plugins.jetbrains.com/plugin/7495--ignore

It manages a lot of paths/patterns for you automatically and also has many useful extra features. It's compatible with:

• IntelliJ IDEA
• PhpStorm
• WebStorm
• PyCharm
• RubyMine
• AppCode
• CLion
• GoLand
• DataGrip
• Rider
• MPS
• Android Studio

I think what you want is mapply. You could apply the function to all columns, and then just drop the columns you don't want. However, if you are applying different functions to different columns, it seems likely what you want is mutate, from the dplyr package.

One option, if you need it done in a pinch, and if your initial column was created with a default, is to create the new column you want, copy the contents over to it, and basically "abandon" the old column (it stays present, but you just don't use/update it, etc.)

ex:

alter table TABLE_NAME ADD COLUMN new_column_name TYPE NOT NULL DEFAULT '';
update TABLE_NAME set new_column_name = old_column_name;
update TABLE_NAME set old_column_name = ''; -- abandon old column, basically

This leaves behind a column (and if it was created with NOT NULL but without a default, then future inserts that ignore it might fail), but if it's just a throwaway table, the tradeoffs might be acceptable. Otherwise use one of the other answers mentioned here, or a different database that allows columns to be renamed.

I had a problem with surefire plugin itself. Going back to version 2.6 worked for me. Version 2.18/20/22.1 gave me the error. Now I tried version 3.0.0-M1 of surefire plugin and it works.

So something is wrong in surefire plgin between version 2.6 and 3.0.0. I assume there is something hardcoded as default which should not.

Note that there are also a number of extensions available that will fix this behaviour for specific contexts of Markdown use.

For example, sane_lists extension of python-markdown (used in mkdocs, for example), will recognize numbers used in Markdown lists. You just need to enable this extension arkdown.markdown(some_text, extensions=['sane_lists'])

<script type="text/javascript">
$('input:text, input:password, textarea').blur(function()
    {
          var check = $(this).val();
          if(check == '')
          {
                $(this).parent().addClass('ym-error');
          }
          else
          {
                $(this).parent().removeClass('ym-error');  
          }
    });
 </script>// :)

I usually use typedef to do it, but it may be overkill, if you do not have to use the function pointer too often..

//assuming bool is available (where I come from it is an enum)

typedef bool (*pmyfun_t)();

pmyfun_t pMyFun;

pMyFun=A; //pMyFun=&A is actually same

pMyFun();

Here is a little extension I just put together.

public static class PositionsExtension
{
    public static Int32 Position<TSource>(this IEnumerable<TSource> source,
                                          Func<TSource, bool> predicate)
    {
        return Positions<TSource>(source, predicate).FirstOrDefault();
    }
    public static IEnumerable<Int32> Positions<TSource>(this IEnumerable<TSource> source, 
                                                        Func<TSource, bool> predicate)
    {
        if (typeof(TSource) is IDictionary)
        {
            throw new Exception("Dictionaries aren't supported");
        }

        if (source == null)
        {
            throw new ArgumentOutOfRangeException("source is null");
        }
        if (predicate == null)
        {
            throw new ArgumentOutOfRangeException("predicate is null");
        }
        var found = source.Where(predicate).First();
        var query = source.Select((item, index) => new
            {
                Found = ReferenceEquals(item, found),
                Index = index

            }).Where( it => it.Found).Select( it => it.Index);
        return query;
    }
}

Then you can call it like this.

IEnumerable<Int32> indicesWhereConditionIsMet = 
      ListItems.Positions(item => item == this);

Int32 firstWelcomeMessage ListItems.Position(msg =>               
      msg.WelcomeMessage.Contains("Hello"));

Generally speaking, a software product isn't your "property already", as you said in the comment. Most of the times (I won't be irresponsible to say anything in open), it's licensed to you. A license to use some thing is not the same thing as owning (property rights) that very same thing.

That's because there are authorship, copyright, intellectual property rights applicable to it. I don't know how things work in United States (or in your country), but it's generally accepted that the work of a mind, a creative work, must not be changed in its nature as such to make the expression of art to be different than that expression that the author intended. That applies for example, in some cases, to architectural work (in most countries, you can't change the appearance of a building to "desfigure" the work of art of the architect, without his prior consent). Exceptions are made, obviously, when the author expressly authorizes such changes (e.g., Creative Commons licenses, open source licenses etc.).

Anyway, that's why you see in most EULAs the typical sentence: "this software is licensed, not sold". That's the purpose and reason why.

Now that you understand the reasons why you can't wander around changing other people's art, let me be technical.

There are possible ways to decompile Java programs. You can use dex2jar, it provides a somewhat good start for you to start looking for things and changes. And perhaps rebuild the code by mounting back the pieces together. Good luck, as most people obfuscate their codes to make that harder.

However, let me say that it's still forbidden to change programs, as I said above. And it's extremely unethical. It makes me sad that people do that with no scruples (not saying it's your case, just warning you). It shouldn't need people to be at the other side to understand that. Or maybe that's just me, who lives in a country where piracy is rampant.

The tools are always out there. But the conscience, unfortunately, not always.

edit: in case it isn't clear enough already, I do NOT approve the use of these programs. I use them myself to check how hard my own applications are to be reverse engineered. But I also think that explaning is always better than denial (better be here).

I had same issue. No need to re install.

Use OOP concept instead. Create a class with function

class MyClass {

...

function getData($query) {
    $result = mysqli_query($this->conn, $query);
    while($row=mysqli_fetch_assoc($result)) {
        $resultset[] = $row;
    }       
    if(!empty($resultset))
        return $resultset;
} }

and then use the class object to call function in your code

<?php 

    $obj = new MyClass();
    $row = $obj->getData("select city_name from city"); 
?>
<select>
    <?php foreach($row as $row){ ?>
        <option><?php echo $row['city_name'] ?></option>

<?php  } ?>
</select>

I know the question is from 2012, but I found the easiest way ever, and I wanted to share.

HTML:

<div id="parent">
     <div id="child">Content here</div>
</div>

and CSS:

#parent{
     height: 100%;
     display: table;
}    
#child {
     display: table-cell;
     vertical-align: middle; 
}

Checkboxes are posting value 'on' if and only if the checkbox is checked. Insted of catching checkbox value you can use hidden inputs

JS:

var chk = $('input[type="checkbox"]');
    chk.each(function(){
        var v = $(this).attr('checked') == 'checked'?1:0;
        $(this).after('<input type="hidden" name="'+$(this).attr('rel')+'" value="'+v+'" />');
    });

chk.change(function(){ 
        var v = $(this).is(':checked')?1:0;
        $(this).next('input[type="hidden"]').val(v);
    });

HTML:

<label>Active</label><input rel="active" type="checkbox" />

a nicer way

app.filter('capitalize', function() {
  return function(token) {
      return token.charAt(0).toUpperCase() + token.slice(1);
   }
});

The tags include 'sendmail' so here's a solution using that:

(
echo "From: [email protected] "
echo "To: [email protected] "
echo "MIME-Version: 1.0"
echo "Content-Type: multipart/alternative; " 
echo ' boundary="some.unique.value.ABC123/server.xyz.com"' 
echo "Subject: Test HTML e-mail." 
echo "" 
echo "This is a MIME-encapsulated message" 
echo "" 
echo "--some.unique.value.ABC123/server.xyz.com" 
echo "Content-Type: text/html" 
echo "" 
echo "<html> 
<head>
<title>HTML E-mail</title>
</head>
<body>
<a href='http://www.google.com'>Click Here</a>
</body>
</html>"
echo "------some.unique.value.ABC123/server.xyz.com--"
) | sendmail -t

A wrapper for sendmail can make this job easier, for example, mutt:

mutt -e 'set content_type="text/html"' [email protected] -s "subject" <  message.html

if os.path.exists(filePath):
    #the file is there
elif os.access(os.path.dirname(filePath), os.W_OK):
    #the file does not exists but write privileges are given
else:
    #can not write there

Note that path.exists can fail for more reasons than just the file is not there so you might have to do finer tests like testing if the containing directory exists and so on.

After my discussion with the OP it turned out, that the main problem seems to be, that the file name might contain characters that are not allowed by the filesystem. Of course they need to be removed but the OP wants to maintain as much human readablitiy as the filesystem allows.

Sadly I do not know of any good solution for this. However Cecil Curry's answer takes a closer look at detecting the problem.

Try This :

In HTML and JS :

// Convert Password Field To Text On Hover._x000D_
  var passField = $('input[type=password]');_x000D_
  $('.show-pass').hover(function() {_x000D_
      passField.attr('type', 'text');_x000D_
  }, function() {_x000D_
    passField.attr('type', 'password');_x000D_
  })

The question asks how to check if a variable is an empty string and the best answers are already given for that.

But I landed here after a period passed programming in PHP, and I was actually searching for a check like the empty function in PHP working in a Bash shell.

After reading the answers I realized I was not thinking properly in Bash, but anyhow in that moment a function like empty in PHP would have been soooo handy in my Bash code.

As I think this can happen to others, I decided to convert the PHP empty function in Bash.

According to the PHP manual:

a variable is considered empty if it doesn't exist or if its value is one of the following:

• "" (an empty string)
• 0 (0 as an integer)
• 0.0 (0 as a float)
• "0" (0 as a string)
• an empty array
• a variable declared, but without a value

Of course the null and false cases cannot be converted in bash, so they are omitted.

function empty
{
    local var="$1"

    # Return true if:
    # 1.    var is a null string ("" as empty string)
    # 2.    a non set variable is passed
    # 3.    a declared variable or array but without a value is passed
    # 4.    an empty array is passed
    if test -z "$var"
    then
        [[ $( echo "1" ) ]]
        return

    # Return true if var is zero (0 as an integer or "0" as a string)
    elif [ "$var" == 0 2> /dev/null ]
    then
        [[ $( echo "1" ) ]]
        return

    # Return true if var is 0.0 (0 as a float)
    elif [ "$var" == 0.0 2> /dev/null ]
    then
        [[ $( echo "1" ) ]]
        return
    fi

    [[ $( echo "" ) ]]
}

Example of usage:

if empty "${var}"
    then
        echo "empty"
    else
        echo "not empty"
fi

Demo:
The following snippet:

#!/bin/bash

vars=(
    ""
    0
    0.0
    "0"
    1
    "string"
    " "
)

for (( i=0; i<${#vars[@]}; i++ ))
do
    var="${vars[$i]}"

    if empty "${var}"
        then
            what="empty"
        else
            what="not empty"
    fi
    echo "VAR \"$var\" is $what"
done

exit

outputs:

VAR "" is empty
VAR "0" is empty
VAR "0.0" is empty
VAR "0" is empty
VAR "1" is not empty
VAR "string" is not empty
VAR " " is not empty

Having said that in a Bash logic the checks on zero in this function can cause side problems imho, anyone using this function should evaluate this risk and maybe decide to cut those checks off leaving only the first one.

For me, the biggest benefit to re.compile is being able to separate definition of the regex from its use.

Even a simple expression such as 0|[1-9][0-9]* (integer in base 10 without leading zeros) can be complex enough that you'd rather not have to retype it, check if you made any typos, and later have to recheck if there are typos when you start debugging. Plus, it's nicer to use a variable name such as num or num_b10 than 0|[1-9][0-9]*.

It's certainly possible to store strings and pass them to re.match; however, that's less readable:

num = "..."
# then, much later:
m = re.match(num, input)

Versus compiling:

num = re.compile("...")
# then, much later:
m = num.match(input)

Though it is fairly close, the last line of the second feels more natural and simpler when used repeatedly.

Jon Skeet has written a library called morelinq which has a DistinctBy() operator. See here for the implementation. Your code would look like

IEnumerable<Note> distinctNotes = Notes.DistinctBy(note => note.Author);

Update: After re-reading your question, Kirk has the correct answer if you're just looking for a distinct set of Authors.

Added sample, several fields in DistinctBy:

res = res.DistinctBy(i => i.Name).DistinctBy(i => i.ProductId).ToList();

In the documentaion http://contactform7.com/text-fields/#textarea

[textarea* message id:contact-message 10x2 placeholder "Your Message"]

The above will generate a textarea with cols="10" and rows="2"

<textarea name="message" cols="10" rows="2" class="wpcf7-form-control wpcf7-textarea wpcf7-validates-as-required" id="contact-message" aria-required="true" aria-invalid="false" placeholder="Your Message"></textarea>

You append a newline to both the username and the password, i.e. the output would be something like

Sebastian
password
John
hfsjaijn

use fwrite($fh,$user." ".$password."\n"); instead to have them both on one line.
Or use fputcsv() to write the data and fgetcsv() to fetch it. This way you would at least avoid encoding problems like e.g. with $username='Charles, III';

...i.e. setting aside all the things that are wrong about storing plain passwords in plain files and using _GET for this type of operation (use _POST instead) ;-)

If you set numberOfLines to 0 (and the label to word wrap), the label will automatically wrap and use as many of lines as needed.

If you're editing a UILabel in IB, you can enter multiple lines of text by pressing option+return to get a line break - return alone will finish editing.

Using your code with some random data, this would work:

fig, axs = plt.subplots(2,5, figsize=(15, 6), facecolor='w', edgecolor='k')
fig.subplots_adjust(hspace = .5, wspace=.001)

axs = axs.ravel()

for i in range(10):

    axs[i].contourf(np.random.rand(10,10),5,cmap=plt.cm.Oranges)
    axs[i].set_title(str(250+i))

The layout is off course a bit messy, but that's because of your current settings (the figsize, wspace etc).

To give an example to what Alex said, if you're using Magento, for example, .phtml files are only to be found in the /design area as template files, and contain both HTML and PHP lines. Meanwhile the PHP files are pure code and don't have any lines of HTML in them.

I have query,

$("#login-button").click(function(e){ alert("hiii");

        var username = $("#username-field").val();
        var password = $("#username-field").val();

        alert(username);
        alert("password" + password);



        var markers = { "userName" : "admin","password" : "admin123"};
        $.ajax({
            type: "POST",
            url: url,
            // The key needs to match your method's input parameter (case-sensitive).
            data: JSON.stringify(markers),
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function(data){alert("got the data"+data);},
            failure: function(errMsg) {
                alert(errMsg);
            }
        });

    });

I'm posting the the login details in json and getting a string as "Success",but I'm not getting the response.

Prefix the call with Module2 (ex. Module2.IDLE). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.

I'll just post the code to do this using the fluent API mapping.

public class User {
    public int UserID { get; set; }
    public string Username { get; set; }
    public string Password { get; set; }

    public ICollection<UserEmail> UserEmails { get; set; }
}

public class Email {
    public int EmailID { get; set; }
    public string Address { get; set; }

    public ICollection<UserEmail> UserEmails { get; set; }
}

public class UserEmail {
    public int UserID { get; set; }
    public int EmailID { get; set; }
    public bool IsPrimary { get; set; }
}

On your DbContext derived class you could do this:

public class MyContext : DbContext {
    protected override void OnModelCreating(DbModelBuilder builder) {
        // Primary keys
        builder.Entity<User>().HasKey(q => q.UserID);
        builder.Entity<Email>().HasKey(q => q.EmailID);
        builder.Entity<UserEmail>().HasKey(q => 
            new { 
                q.UserID, q.EmailID
            });

        // Relationships
        builder.Entity<UserEmail>()
            .HasRequired(t => t.Email)
            .WithMany(t => t.UserEmails)
            .HasForeignKey(t => t.EmailID)

        builder.Entity<UserEmail>()
            .HasRequired(t => t.User)
            .WithMany(t => t.UserEmails)
            .HasForeignKey(t => t.UserID)
    }
}

It has the same effect as the accepted answer, with a different approach, which is no better nor worse.

You can do so by these ways.

Add watchpoint and while debugging you can see variable in debugger window perspective under variable tab. OR Add System.out.println("variable = " + variable); and see in console.

It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==, the following should work:

byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

This will output: YWJjZGVmPT0= which is abcdef== encoded in Base64.

Edit:

To decode a Base64 string, simply use Convert.FromBase64String(). E.g.

string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);

At this point, bytes will be a byte[] (not a string). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:

string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);

This will output the original input string, abcdef== in this case.
