Yes, right click the project. Click Run as then Run Configurations. You can change the parameters passed to the JVM in the Arguments tab in the VM Arguments box.

That configuration can then be used as the default when running the project.

In MS Windows the temporary directory is set by the environment variable TEMP. In XP, the temporary directory was set per-user as Local Settings\Temp.

If you change your TEMP environment variable to C:\temp, then you get the same when you run :

System.out.println(System.getProperty("java.io.tmpdir"));

You forgot braces around the if block, and a semicolon between the statements in the block.

awk '{if($3 != 0) {a = ($3/$4); print $0, a;} else if($3==0) print $0, "-" }' file > out

Just use

y_pred = (y_pred > 0.5)
accuracy_score(y_true, y_pred, normalize=False)

As stated in a similar question, try removing instances of the input-group class and see if that helps.

refering to bootstrap:

Individual form controls automatically receive some global styling. All textual , , and elements with .form-control are set to width: 100%; by default. Wrap labels and controls in .form-group for optimum spacing.

u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)

Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.

Doing a 302 will typically cause clients to convert a POST to a GET request.

You can use $routeProvider resolve property to delay route change until data is loaded.

angular.module('app', ['ngRoute']).
  config(['$routeProvider', function($routeProvider, EntitiesCtrlResolve, EntityCtrlResolve) {
    $routeProvider.
      when('/entities', {
        templateUrl: 'entities.html', 
        controller: 'EntitiesCtrl', 
        resolve: EntitiesCtrlResolve
      }).
      when('/entity/:entityId', {
        templateUrl: 'entity.html', 
        controller: 'EntityCtrl', 
        resolve: EntityCtrlResolve
      }).
      otherwise({redirectTo: '/entities'});
}]);

Notice that the resolve property is defined on route.

EntitiesCtrlResolve and EntityCtrlResolve is constant objects defined in same file as EntitiesCtrl and EntityCtrl controllers.

// EntitiesCtrl.js

angular.module('app').constant('EntitiesCtrlResolve', {
  Entities: function(EntitiesService) {
    return EntitiesService.getAll();
  }
});

angular.module('app').controller('EntitiesCtrl', function(Entities) {
  $scope.entities = Entities;

  // some code..
});

// EntityCtrl.js

angular.module('app').constant('EntityCtrlResolve', {
  Entity: function($route, EntitiesService) {
    return EntitiesService.getById($route.current.params.projectId);
  }
});

angular.module('app').controller('EntityCtrl', function(Entity) {
  $scope.entity = Entity;

  // some code..
});

Here is an answer that should work in all cases:

def is_empty(s):
    "Check whether a string is empty"
    return not s or not s.strip()

If the variable is None, it will stop at not sand not evaluate further (since not None == True). Apparently, the strip()method takes care of the usual cases of tab, newline, etc.

Sorry not sure what was going on this worked in the end:

<VirtualHost *> 
    ServerName example.com
    DocumentRoot /var/www/html/mjp

    Alias /ncn "/var/www/html/ncn"

    <Directory "/var/www/html/ncn">
        Options None
        AllowOverride None
        Order allow,deny
        Allow from all
    </Directory>
</VirtualHost>

Add !importent in your css

* {
   font-size: 16px !importent;
   line-height: 2;
}

Stop the IIS service. It should work then

You post JSON like this

$.ajax(url, {
    data : JSON.stringify(myJSObject),
    contentType : 'application/json',
    type : 'POST',
    ...

if you pass an object as settings.data jQuery will convert it to query parameters and by default send with the data type application/x-www-form-urlencoded; charset=UTF-8, probably not what you want

The first thing you should do is learn to read error messages. What does it tell you -- that you can't use two strings with the divide operator.

So, ask yourself why they are strings and how do you make them not-strings. They are strings because all input is done via strings. And the way to make then not-strings is to convert them.

One way to convert a string to an integer is to use the int function. For example:

percent = (int(pyc) / int(tpy)) * 100

Here's my solution in C. Hope this helps!

int next_power_of_two(int n) {
    int i = 0;
    for (--n; n > 0; n >>= 1) {
        i++;
    }
    return 1 << i;
}

Use the sizing utility classes...

• h-100 = height 100%

To illustrate my comment on Andy's answer, with additional file descriptor manipulation to avoid use of /dev/tty:

#!/bin/bash

exec 3>&1

returnString() {
    exec 4>&1 >&3
    local s=$1
    s=${s:="some default string"}
    echo "writing to stdout"
    echo "writing to stderr" >&2
    exec >&4-
    echo "$s"
}

my_string=$(returnString "$*")
echo "my_string:  [$my_string]"

Still nasty, though.

Essentially the same as Mike Ramirez's answer, but simpler and closer in stylistics to django standard get_absolute_url method:

from django.urls import reverse

def get_admin_url(self):
    return reverse('admin:%s_%s_change' % (self._meta.app_label, self._meta.model_name),
                   args=[self.id])

I am using Chosen. Look at: http://harvesthq.github.io/chosen/

It works on Firefox, Chrome, IE and Safari with the same style. But not on Mobile Devices.

Here is an example that works with multibyte ( UTF-8 ) strings.

$str = 'äbcd';

// PHP 5.4.8 allows null as the third argument of mb_strpos() function
do {
    $arr[] = mb_substr( $str, 0, 1, 'utf-8' );
} while ( $str = mb_substr( $str, 1, mb_strlen( $str ), 'utf-8' ) );

It can be also done with preg_split() ( preg_split( '//u', $str, null, PREG_SPLIT_NO_EMPTY ) ), but unlike the above example, that runs almost as fast regardless of the size of the string, preg_split() is fast with small strings, but a lot slower with large ones.

For anyone who is still having issues after trying all the answers on this page, the following (finally) worked:

sudo apt-get install libgmp3-dev
gem install pg

This was after doing everything else mentioned on this page.

The init(frame:) version is the default initializer. You must call it only after initializing your instance variables. If this view is being reconstituted from a Nib then your custom initializer will not be called, and instead the init?(coder:) version will be called. Since Swift now requires an implementation of the required init?(coder:), I have updated the example below and changed the let variable declarations to var and optional. In this case, you would initialize them in awakeFromNib() or at some later time.

class TestView : UIView {
    var s: String?
    var i: Int?
    init(s: String, i: Int) {
        self.s = s
        self.i = i
        super.init(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
    }

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

Simple and Best

echo date('Y-m-d H:i:s')."\n";
echo "<br>";
echo date('Y-m-d H:i:s', mktime(date('H'),date('i'),date('s'), date('m'),date('d')+30,date('Y')))."\n";

Try this

Every time a new device is opened par() will reset, so another option is simply do dev.off() and continue.

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

Newer versions of svn support the --show-item argument:

svn info --show-item revision

For the revision number of your local working copy, use:

svn info --show-item last-changed-revision

You can use os.system() to execute a command line like this:

svn info | grep "Revision" | awk '{print $2}'

I do that in my nightly build scripts.

Also on some platforms there is a svnversion command, but I think I had a reason not to use it. Ahh, right. You can't get the revision number from a remote repository to compare it to the local one using svnversion.

Use the CLIM function (equivalent to CAXIS function in MATLAB):

plt.pcolor(X, Y, v, cmap=cm)
plt.clim(-4,4)  # identical to caxis([-4,4]) in MATLAB
plt.show()

If you mean use the same code but add a new line so that when you add something to the file it will be on a new line. You can simply use BufferedWriter's newLine().
Here I have Improved you code also: NumberFormatException was unnecessary as nothing was being cast to a number data type, saving variables to use once also was.

try {
    BufferedWriter writer = new BufferedWriter(new FileWriter("file.txt"));
        writer.write(jTextField1.getText());
        writer.write(jTextField2.getText());
        writer.newLine();
        writer.flush();
        writer.close();
} catch (IOException ex) {
    System.out.println("File could not be created");
}

OpenCV has support for getting data from a webcam, and it comes with Python wrappers by default, you also need to install numpy for the OpenCV Python extension (called cv2) to work. As of 2019, you can install both of these libraries with pip: pip install numpy pip install opencv-python

More information on using OpenCV with Python.

An example copied from Displaying webcam feed using opencv and python:

import cv2

cv2.namedWindow("preview")
vc = cv2.VideoCapture(0)

if vc.isOpened(): # try to get the first frame
    rval, frame = vc.read()
else:
    rval = False

while rval:
    cv2.imshow("preview", frame)
    rval, frame = vc.read()
    key = cv2.waitKey(20)
    if key == 27: # exit on ESC
        break
cv2.destroyWindow("preview")

Create a new style

<!-- Theme.AppCompat.Light.Dialog -->
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
    <item name="colorAccent">@color/blue_500</item>
</style>

Java code:

The parent theme is the key here. Choose your colorAccent

DatePickerDialog = new DatePickerDialog(context,R.style.DialogTheme,this,now.get(Calendar.YEAR),now.get(Calendar.MONTH),now.get(Calendar.DAY_OF_MONTH);

Result:

A lambda is an anonymous function:

>>> f = lambda: 'foo'
>>> print f()
foo

It is often used in functions such as sorted() that take a callable as a parameter (often the key keyword parameter). You could provide an existing function instead of a lambda there too, as long as it is a callable object.

Take the sorted() function as an example. It'll return the given iterable in sorted order:

>>> sorted(['Some', 'words', 'sort', 'differently'])
['Some', 'differently', 'sort', 'words']

but that sorts uppercased words before words that are lowercased. Using the key keyword you can change each entry so it'll be sorted differently. We could lowercase all the words before sorting, for example:

>>> def lowercased(word): return word.lower()
...
>>> lowercased('Some')
'some'
>>> sorted(['Some', 'words', 'sort', 'differently'], key=lowercased)
['differently', 'Some', 'sort', 'words']

We had to create a separate function for that, we could not inline the def lowercased() line into the sorted() expression:

>>> sorted(['Some', 'words', 'sort', 'differently'], key=def lowercased(word): return word.lower())
  File "<stdin>", line 1
    sorted(['Some', 'words', 'sort', 'differently'], key=def lowercased(word): return word.lower())
                                                           ^
SyntaxError: invalid syntax

A lambda on the other hand, can be specified directly, inline in the sorted() expression:

 >>> sorted(['Some', 'words', 'sort', 'differently'], key=lambda word: word.lower())
['differently', 'Some', 'sort', 'words']

Lambdas are limited to one expression only, the result of which is the return value.

There are loads of places in the Python library, including built-in functions, that take a callable as keyword or positional argument. There are too many to name here, and they often play a different role.

Try this:

import base64
imgdata = base64.b64decode(imgstring)
filename = 'some_image.jpg'  # I assume you have a way of picking unique filenames
with open(filename, 'wb') as f:
    f.write(imgdata)
# f gets closed when you exit the with statement
# Now save the value of filename to your database

Short answer

Just copy an image into your res/drawable folder and use

imageView.setImageResource(R.drawable.my_image);

Details

The variety of answers can cause a little confusion. We have

• setBackgroundResource()
• setBackgroundDrawable()
• setBackground()
• setImageResource()
• setImageDrawable()
• setImageBitmap()

The methods with Background in their name all belong to the View class, not to ImageView specifically. But since ImageView inherits from View you can use them, too. The methods with Image in their name belong specifically to ImageView.

The View methods all do the same thing as each other (though setBackgroundDrawable() is deprecated), so we will just focus on setBackgroundResource(). Similarly, the ImageView methods all do the same thing, so we will just focus on setImageResource(). The only difference between the methods is they type of parameter you pass in.

Setup

Here is a FrameLayout that contains an ImageView. The ImageView initially doesn't have any image in it. (I only added the FrameLayout so that I could put a border around it. That way you can see the edge of the ImageView.)

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/frameLayout"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:background="@drawable/border"
        android:layout_centerInParent="true">

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

    </FrameLayout>
</RelativeLayout>

Below we will compare the different methods.

setImageResource()

If you use ImageView's setImageResource(), then the image keeps its aspect ratio and is resized to fit. Here are two different image examples.

• imageView.setImageResource(R.drawable.sky);
• imageView.setImageResource(R.drawable.balloons);

setBackgroundResource()

Using View's setBackgroundResource(), on the other hand, causes the image resource to be stretched to fill the view.

• imageView.setBackgroundResource(R.drawable.sky);
• imageView.setBackgroundResource(R.drawable.balloons);

Both

The View's background image and the ImageView's image are drawn separately, so you can set them both.

imageView.setBackgroundResource(R.drawable.sky);
imageView.setImageResource(R.drawable.balloons);

Depends on what they looked like. I use gitx which makes pictures like this one:

You can compare git log --graph vs. gitk on a 24-way octopus merge (originally from http://clojure-log.n01se.net/date/2008-12-24.html):

jQlite (angular's "jQuery" port) doesn't support lookup by classes.

One solution would be to include jQuery in your app.

Another is using QuerySelector or QuerySelectorAll:

link: function(scope, element, attrs) {
   console.log(element[0].querySelector('.list-scrollable'))
}

We use the first item in the element array, which is the HTML element. element.eq(0) would yield the same.

FIDDLE

It's a parameter. You can specify it when executing query.

Because of things like this, as a general rule of thumb, I try to avoid as much XAML "trickery" as possible and keep the XAML as dumb and simple as possible and do the rest in the ViewModel (or attached properties or IValueConverters etc. if really necessary).

If possible I would give the ViewModel of the current DataContext a reference (i.e. property) to the relevant parent ViewModel

public class ThisViewModel : ViewModelBase
{
    TypeOfAncestorViewModel Parent { get; set; }
}

and bind against that directly instead.

<TextBox Text="{Binding Parent}" />

BigDecimal no = new BigDecimal(10); //you can add like this also
no = no.add(new BigDecimal(10));
System.out.println(no);

There is a command (not a part of core Git, but it is in the git-extras package) specifically for reverting and staging old commits:

git back

Per the man page, it can also be used as such:

# Remove the latest three commits
git back 3

EOF is -1 because that's how it's defined. The name is provided by the standard library headers that you #include. They make it equal to -1 because it has to be something that can't be mistaken for an actual byte read by getchar(). getchar() reports the values of actual bytes using positive number (0 up to 255 inclusive), so -1 works fine for this.

The != operator means "not equal". 0 stands for false, and anything else stands for true. So what happens is, we call the getchar() function, and compare the result to -1 (EOF). If the result was not equal to EOF, then the result is true, because things that are not equal are not equal. If the result was equal to EOF, then the result is false, because things that are equal are not (not equal).

The call to getchar() returns EOF when you reach the "end of file". As far as C is concerned, the 'standard input' (the data you are giving to your program by typing in the command window) is just like a file. Of course, you can always type more, so you need an explicit way to say "I'm done". On Windows systems, this is control-Z. On Unix systems, this is control-D.

The example in the book is not "wrong". It depends on what you actually want to do. Reading until EOF means that you read everything, until the user says "I'm done", and then you can't read any more. Reading until '\n' means that you read a line of input. Reading until '\0' is a bad idea if you expect the user to type the input, because it is either hard or impossible to produce this byte with a keyboard at the command prompt :)

The Inversion of Control (IoC) and Dependency Injection (DI) patterns are all about removing dependencies from your code.

For example, say your application has a text editor component and you want to provide spell checking. Your standard code would look something like this:

public class TextEditor {

    private SpellChecker checker;

    public TextEditor() {
        this.checker = new SpellChecker();
    }
}

What we've done here creates a dependency between the TextEditor and the SpellChecker. In an IoC scenario we would instead do something like this:

public class TextEditor {

    private IocSpellChecker checker;

    public TextEditor(IocSpellChecker checker) {
        this.checker = checker;
    }
}

In the first code example we are instantiating SpellChecker (this.checker = new SpellChecker();), which means the TextEditor class directly depends on the SpellChecker class.

In the second code example we are creating an abstraction by having the SpellChecker dependency class in TextEditor's constructor signature (not initializing dependency in class). This allows us to call the dependency then pass it to the TextEditor class like so:

SpellChecker sc = new SpellChecker(); // dependency
TextEditor textEditor = new TextEditor(sc);

Now the client creating the TextEditor class has control over which SpellChecker implementation to use because we're injecting the dependency into the TextEditor signature.

I had the same problem using PHP and prepared statements on a VARCHAR2 column. My string didn't exceeed the VARCHAR2 size. The problem was that I used -1 as maxlength for binding, but the variable content changed later.

In example:

$sMyVariable = '';
$rParsedQuery = oci_parse($rLink, 'INSERT INTO MyTable (MyVarChar2Column) VALUES (:MYPLACEHOLDER)');
oci_bind_by_name($rParsedQuery, ':MYPLACEHOLDER', $sMyVariable, -1, SQLT_CHR);

$sMyVariable = 'a';
oci_execute($rParsedQuery, OCI_DEFAULT);
$sMyVariable = 'b';
oci_execute($rParsedQuery, OCI_DEFAULT);

If you replace the -1 with the max column width (i. e. 254) then this code works. With -1 oci_bind_by_param uses the current length of the variable content (in my case 0) as maximum length for this column. This results in ORA-01461 when executing.

As per https://android.stackexchange.com/a/78183/239063 you can run a one line command in Linux to add in an appropriate tar header to extract it.

( printf "\x1f\x8b\x08\x00\x00\x00\x00\x00" ; tail -c +25 backup.ab ) | tar xfvz -

Replace backup.ab with the path to your file.

check the name of the database in a file where you established a connection.

you can try just add

network_mode: "host"

example :

version: '2'
services:
  feedx:
    build: web
    ports:
    - "127.0.0.1:8000:8000"
    network_mode: "host"

list option available

network_mode: "bridge"
network_mode: "host"
network_mode: "none"
network_mode: "service:[service name]"
network_mode: "container:[container name/id]"

Because it's all just about memory, in the end all the numerical values are stored in binary.

A 32 bit unsigned integer can contain values from all binary 0s to all binary 1s.

When it comes to 32 bit signed integer, it means one of its bits (most significant) is a flag, which marks the value to be positive or negative.

In case it helps anyone... I was having a lot of trouble with setting up notifications using the support package when testing against newer an older API's. I was able to get them to work on the newer device but would get an error testing on the old device. What finally got it working for me was to delete all the imports related to the notification functions. In particular the NotificationCompat and the TaskStackBuilder. It seems that while setting up my code in the beginning the imports where added from the newer build and not from the support package. Then when I wanted to implement these items later in eclipse, I wasn't prompted to import them again. Hope that makes sense, and that it helps someone else out :)

If you don't create the DOM yourself (e.g. in a userscript) you can do the following with pure JS:

for ( td of document.querySelectorAll('td') ) {_x000D_
  console.debug("text:", td, td.innerText)_x000D_
  td.setAttribute('text', td.innerText)_x000D_
}_x000D_
for ( td of document.querySelectorAll('td[text="male"]') )_x000D_
  console.debug("male:", td, td.innerText)

<table>_x000D_
  <tr>_x000D_
    <td>Peter</td>_x000D_
    <td>male</td>_x000D_
    <td>34</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Susanne</td>_x000D_
    <td>female</td>_x000D_
    <td>12</td>_x000D_
  </tr>_x000D_
</table>

Console output

text: <td> Peter
text: <td> male
text: <td> 34
text: <td> Susanne
text: <td> female
text: <td> 12
male: <td text="male"> male

I had a more basic problem when I received this error.

The "Validate your installation" instructions say to type: python

However, I have both 2.7 and 3.6 installed. Because I used pip3 to install tensorflow, I needed to type: python3

Using the correct version, I could import the "tensorflow" module.

Right-click on the widget and choose "center" -> "horizontally". Then choose "center"->"vertically".

You can also try this: Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37 In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.

Ctrl+Space : Show Imports

This displays imports as you're typing a non-standard class name provided the proper references have been added to the project.

This works on partial or complete class names as you are typing them or after the fact (Just place the cursor back on the class name with squigglies).

Just simply write BETWEEN '{$startDate}' AND '{$endDate}' in where condition as

->where("date BETWEEN '{$startDate}' AND '{$endDate}'")

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

$(this).dialog('destroy').remove()

This will destroy the dialog and then remove the div that was "hosting" the dialog completely from the DOM

all you can do is to navigate to your jre destination in your computer via command line and then once you reach bin, you type the keytool command and it would work.

C:\Program Files (x86)\Java\jre7\bin>
C:\Program Files (x86)\Java\jre7\bin>keytool -list -v -keystore"%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

This is probably too late, but I had a similar problem with dates that I wanted entered into cells from a text variable. Inevitably, it converted my variable text value to a date. What I finally had to do was concatentate a ' to the string variable and then put it in the cell like this:

prvt_rng_WrkSht.Cells(prvt_rng_WrkSht.Rows.Count, cnst_int_Col_Start_Date).Formula = "'" & _ 
    param_cls_shift.Start_Date (string property of my class) 

Simply the answer according to my reading and understanding to this thread and @remus-rusanu answer is based on this simple scenario:

There are two transactions A and B. Transaction B is reading Table X Transaction A is writing in table X Transaction B is reading again in Table X.

• ReadUncommitted: Transaction B can read uncommitted data from Transaction A and it could see different rows based on B writing. No lock at all
• ReadCommitted: Transaction B can read ONLY committed data from Transaction A and it could see different rows based on COMMITTED only B writing. could we call it Simple Lock?
• RepeatableRead: Transaction B will read the same data (rows) whatever Transaction A is doing. But Transaction A can change other rows. Rows level Block
• Serialisable: Transaction B will read the same rows as before and Transaction A cannot read or write in the table. Table-level Block
• Snapshot: every Transaction has its own copy and they are working on it. Each one has its own view

for me it was because in /etc/hosts file the hostname is not added

>>> dict(zip([1, 2, 3, 4], ['a', 'b', 'c', 'd']))
{1: 'a', 2: 'b', 3: 'c', 4: 'd'}

If they are not the same size, zip will truncate the longer one.

i did try this and its working in windows machine to run a sql file on a specific schema.

psql -h localhost -p 5432 -U username -d databasename -v schema=schemaname < e:\Table.sql

Step 1: View page code

<input type="button" id="btnExport" value="Export" class="btn btn-primary" />
<script>
  $(document).ready(function () {

 $('#btnExport').click(function () {          

  window.location = '/Inventory/ExportInventory';

        });
});
</script>

Step 2: Controller Code

  public ActionResult ExportInventory()
        {
            //Load Data
            var dataInventory = _inventoryService.InventoryListByPharmacyId(pId);
            string xml=String.Empty;
            XmlDocument xmlDoc = new XmlDocument();

            XmlSerializer xmlSerializer = new XmlSerializer(dataInventory.GetType());

            using (MemoryStream xmlStream = new MemoryStream())
            {
                xmlSerializer.Serialize(xmlStream, dataInventory);
                xmlStream.Position = 0;
                xmlDoc.Load(xmlStream);
                xml = xmlDoc.InnerXml;
            }

            var fName = string.Format("Inventory-{0}", DateTime.Now.ToString("s"));

            byte[] fileContents = Encoding.UTF8.GetBytes(xml);

            return File(fileContents, "application/vnd.ms-excel", fName);
        }

Shortest form (without having to install random libraries) ?

public static void play(String filename)
{
    try
    {
        Clip clip = AudioSystem.getClip();
        clip.open(AudioSystem.getAudioInputStream(new File(filename)));
        clip.start();
    }
    catch (Exception exc)
    {
        exc.printStackTrace(System.out);
    }
}

The only problem is there is no good way to make this method blocking to close and dispose the data after *.wav finishes. clip.drain() says it's blocking but it's not. The clip isn't running RIGHT AFTER start(). The only working but UGLY way I found is:

// ...
clip.start();
while (!clip.isRunning())
    Thread.sleep(10);
while (clip.isRunning())
    Thread.sleep(10);
clip.close();

        public static void ReminderDigints(decimal? number, out decimal? Value,  out decimal? Reminder)
        {
            Reminder = null;
            Value = null;
            if (number.HasValue)
            {
                Value = Math.Floor(number.Value);
                Reminder = (number - Math.Truncate(number.Value));
            }
        }



        decimal? number= 50.55m;             
        ReminderDigints(number, out decimal? Value, out decimal? Reminder);

Try:

java -cp . Echo "hello"

Assuming that you compiled with:

javac Echo.java 

Then there is a chance that the "current" directory is not in your classpath ( where java looks for .class definitions )

If that's the case and listing the contents of your dir displays:

Echo.java
Echo.class

Then any of this may work:

java -cp . Echo "hello"

or

SET CLASSPATH=%CLASSPATH;.  

java Echo "hello"

And later as Fredrik points out you'll get another error message like.

Exception in thread "main" java.lang.NoSuchMethodError: main

When that happens, go and read his answer :)

In PowerShell and PowerShell ISE, it is also possible to use Shift + Enter at the end of each line for multiline editing (instead of standard backtick `).

float is the closest equivalent.

SqlDbType Enumeration

For Lat/Long as OP mentioned.

A metre is 1/40,000,000 of the latitude, 1 second is around 30 metres. Float/double give you 15 significant figures. With some quick and dodgy mental arithmetic... the rounding/approximation errors would be the about the length of this fill stop -> "."

It seem like your Resort method doesn't declare a compareTo method. This method typically belongs to the Comparable interface. Make sure your class implements it.

Additionally, the compareTo method is typically implemented as accepting an argument of the same type as the object the method gets invoked on. As such, you shouldn't be passing a String argument, but rather a Resort.

Alternatively, you can compare the names of the resorts. For example

if (resortList[mid].getResortName().compareTo(resortName)>0)  

In short, it lets you assign values to a variable in an outer (but non-global) scope. See PEP 3104 for all the gory details.

There could be only two things in settings.py which causes problems for you.

1) STATIC_URL = '/static/'

2)

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, "static"),
)

and your static files should lie under static directory which is in same directory as project's settings file.

Even then if your static files are not loading then reason is , you might have kept

DEBUG = False

change it to True (strictly for development only). In production just change STATICFILES_DIRS to whatever path where static files resides.

It's just a principle about exposure APIs.

Using python, It's a good idea to avoid exposure API in outer space(module or class), function is a good encapsulation place.

It could be a good idea. when you ensure

1. inner function is ONLY used by outer function.
2. insider function has a good name to explain its purpose because the code talks.
3. code cannot directly understand by your colleagues(or other code-reader).

Even though, Abuse this technique may cause problems and implies a design flaw.

Just from my exp, Maybe misunderstand your question.

For ubuntu users, this error may arise because setuptool is not installed system-wide. Simply install setuptool using the command:

sudo apt-get install -y python-setuptools

For python3:

sudo apt-get install -y python3-setuptools

After that, install your package again normally, using

sudo python setup.py install

That's all.

Here's a working solution (2019): put this code inside your login logic;

 GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                @Override
                public void onCompleted(JSONObject json, GraphResponse response) {
                    // Application code
                    if (response.getError() != null) {
                        System.out.println("ERROR");
                    } else {
                        System.out.println("Success");
                        String jsonresult = String.valueOf(json);
                        System.out.println("JSON Result" + jsonresult);

                        String fbUserId = json.optString("id");
                        String fbUserFirstName = json.optString("name");
                        String fbUserEmail = json.optString("email");
                        //String fbUserProfilePics = "http://graph.facebook.com/" + fbUserId + "/picture?type=large";
                        Log.d("SignUpActivity", "Email: " + fbUserEmail + "\nName: " + fbUserFirstName + "\nID: " + fbUserId);
                    }
                    Log.d("SignUpActivity", response.toString());
                }
            });
            Bundle parameters = new Bundle();
            parameters.putString("fields", "id,name,email,gender, birthday");
            request.setParameters(parameters);
            request.executeAsync();
        }

        @Override
        public void onCancel() {
            setResult(RESULT_CANCELED);
            Toast.makeText(SignUpActivity.this, "Login Attempt Cancelled", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onError(FacebookException error) {
            Toast.makeText(SignUpActivity.this, "An Error Occurred", Toast.LENGTH_LONG).show();
            error.printStackTrace();
        }
    });

p is the conversion specifier to print pointers. Use this.

int a = 42;

printf("%p\n", (void *) &a);

Remember that omitting the cast is undefined behavior and that printing with p conversion specifier is done in an implementation-defined manner.

easy way

   someString.replace(' ', '');

One way to handle this is to do it in a transaction, and make your SELECT query take an update lock on the rows selected until the transaction completes.

BEGIN TRAN

SELECT Id FROM Table1 WITH (UPDLOCK)
WHERE AlertDate IS NULL;

UPDATE Table1 SET AlertDate = getutcdate() 
WHERE AlertDate IS NULL;

COMMIT TRAN 

This eliminates the possibility that a concurrent client updates the rows selected in the moment between your SELECT and your UPDATE.

When you commit the transaction, the update locks will be released.

Another way to handle this is to declare a cursor for your SELECT with the FOR UPDATE option. Then UPDATE WHERE CURRENT OF CURSOR. The following is not tested, but should give you the basic idea:

DECLARE cur1 CURSOR FOR
  SELECT AlertDate FROM Table1 
  WHERE AlertDate IS NULL
  FOR UPDATE;

DECLARE @UpdateTime DATETIME

SET @UpdateTime = GETUTCDATE()

OPEN cur1;

FETCH NEXT FROM cur1;

WHILE @@FETCH_STATUS = 0
BEGIN

  UPDATE Table1 
  SET AlertDate = @UpdateTime  --set value
  WHERE CURRENT OF cur1;

  FETCH NEXT FROM cur1;
  
END

You should use thenReturn or doReturn when you know the return value at the time you mock a method call. This defined value is returned when you invoke the mocked method.

thenReturn(T value) Sets a return value to be returned when the method is called.

@Test
public void test_return() throws Exception {
    Dummy dummy = mock(Dummy.class);
    int returnValue = 5;

    // choose your preferred way
    when(dummy.stringLength("dummy")).thenReturn(returnValue);
    doReturn(returnValue).when(dummy).stringLength("dummy");
}

Answer is used when you need to do additional actions when a mocked method is invoked, e.g. when you need to compute the return value based on the parameters of this method call.

Use doAnswer() when you want to stub a void method with generic Answer.

Answer specifies an action that is executed and a return value that is returned when you interact with the mock.

@Test
public void test_answer() throws Exception {
    Dummy dummy = mock(Dummy.class);
    Answer<Integer> answer = new Answer<Integer>() {
        public Integer answer(InvocationOnMock invocation) throws Throwable {
            String string = invocation.getArgumentAt(0, String.class);
            return string.length() * 2;
        }
    };

    // choose your preferred way
    when(dummy.stringLength("dummy")).thenAnswer(answer);
    doAnswer(answer).when(dummy).stringLength("dummy");
}

Environ() gets you the value of any environment variable. These can be found by doing the following command in the Command Prompt:

set

If you wanted to get the username, you would do:

Environ("username")

If you wanted to get the fully qualified name, you would do:

Environ("userdomain") & "\" & Environ("username")

This is how to use chai to deeply test associative arrays.

I had an issue trying to assert that two associative arrays were equal. I know that these shouldn't really be used in javascript but I was writing unit tests around legacy code which returns a reference to an associative array. :-)

I did it by defining the variable as an object (not array) prior to my function call:

var myAssocArray = {};   // not []
var expectedAssocArray = {};  // not []

expectedAssocArray['myKey'] = 'something';
expectedAssocArray['differentKey'] = 'something else';

// legacy function which returns associate array reference
myFunction(myAssocArray);

assert.deepEqual(myAssocArray, expectedAssocArray,'compare two associative arrays');

You need to go there

/jdk1.8.0_152 | /jre | /lib | /security | java.security and uncomment the

#crypto.policy=unlimited

to

crypto.policy=unlimited

A way around this would be to use Object datatype instead:

Private _myDate As Object
Private Property MyDate As Date
    Get
        If IsNothing(_myDate) Then Return Nothing
        Return CDate(_myDate)
    End Get
    Set(value As Date)
        If date = Nothing Then
            _myDate = Nothing
            Return
        End If
        _myDate = value
     End Set
End Property

Then you can set the date to nothing like so:

MyDate = Nothing
Dim theDate As Date = MyDate
If theDate = Nothing Then
    'date is nothing
End If

Use the remove() method:

$(this).children("ul").remove();

Here is how removed special characters.

I simply applied regex

Dim strPattern As String: strPattern = "[^a-zA-Z0-9]" 'The regex pattern to find special characters
Dim strReplace As String: strReplace = "" 'The replacement for the special characters
Set regEx = CreateObject("vbscript.regexp") 'Initialize the regex object    
Dim GCID As String: GCID = "Text #N/A" 'The text to be stripped of special characters

' Configure the regex object
With regEx
    .Global = True
    .MultiLine = True
    .IgnoreCase = False
    .Pattern = strPattern
End With

' Perform the regex replacement
GCID = regEx.Replace(GCID, strReplace)

Here is example how to remove NULL characters using ex (in-place):

ex -s +"%s/\%x00//g" -cwq nulls.txt

and for multiple files:

ex -s +'bufdo!%s/\%x00//g' -cxa *.txt

^{For recursivity, you may use globbing option **/*.txt (if it is supported by your shell).}

Useful for scripting since sed and its -i parameter is a non-standard BSD extension.

See also: How to check if the file is a binary file and read all the files which are not?

In a word, no. It's not possible using the Selenium WebDriver API. This has been discussed ad nauseam in the issue tracker for the project, and the feature will not be added to the API.

Yes, Mid.

Dim sub_str
sub_str = Mid(source_str, 10, 5)

The first parameter is the source string, the second is the start index, and the third is the length.

@bobobobo: Note that VBScript strings are 1-based, not 0-based. Passing 0 as an argument to Mid results in "invalid procedure call or argument Mid".

First you are trying to write to the innerHTML of the input field. This will not work. You need to have a div or span to write to. Try something like:

First_Name
<input type=text id=fname name=fname onblur="validate()"> </input>
<div id="fname_error"></div>

Then change your validate function to read

if(myform.fname.value.length==0)
    {
    document.getElementById("fname_error").innerHTML="this is invalid name ";
    }

Second, I'm always hesitant about using onBlur for this kind of thing. It is possible to submit a form without exiting the field (e.g. return key) in which case your validation code will not be executed. I prefer to run the validation from the button that submits the form and then call the submit() from within the function only if the document has passed validation.

As mentioned the basic Date() can do what you need in terms of getting the current time. In my recent experience working heavily with Java dates there are a lot of oddities with the built in classes (as well as deprecation of many of the Date class methods). One oddity that stood out to me was that months are 0 index based which from a technical standpoint makes sense, but in real terms can be very confusing.

If you are only concerned with the current date that should suffice - however if you intend to do a lot of manipulating/calculations with dates it could be very beneficial to use a third party library (so many exist because many Java developers have been unsatisfied with the built in functionality).

I second Stephen C's recommendation as I have found Joda-time to be very useful in simplifying my work with dates, it is also very well documented and you can find many useful examples throughout the web. I even ended up writing a static wrapper class (as DateUtils) which I use to consolidate and simplify all of my common date manipulation.

This is what I'm using nowadays if the test result is produced asynchronously.

public class TestUtil {

    public static <R> R await(Consumer<CompletableFuture<R>> completer) {
        return await(20, TimeUnit.SECONDS, completer);
    }

    public static <R> R await(int time, TimeUnit unit, Consumer<CompletableFuture<R>> completer) {
        CompletableFuture<R> f = new CompletableFuture<>();
        completer.accept(f);
        try {
            return f.get(time, unit);
        } catch (InterruptedException | TimeoutException e) {
            throw new RuntimeException("Future timed out", e);
        } catch (ExecutionException e) {
            throw new RuntimeException("Future failed", e.getCause());
        }
    }
}

Using static imports, the test reads kinda nice. (note, in this example I'm starting a thread to illustrate the idea)

    @Test
    public void testAsync() {
        String result = await(f -> {
            new Thread(() -> f.complete("My Result")).start();
        });
        assertEquals("My Result", result);
    }

If f.complete isn't called, the test will fail after a timeout. You can also use f.completeExceptionally to fail early.

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock

True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

The input won't have a value if it doesn't exist. Try this...

if($('.input1').val())

To really get this clear, here's my for-beginners answer: You inputed the arguments in the wrong order.
A keyword argument has this style:

nullable=True, unique=False

A fixed parameter should be defined: True, False, etc. A non-keyword argument is different:

name="Ricardo", fruit="chontaduro" 

This syntax error asks you to first put name="Ricardo" and all of its kind (non-keyword) before those like nullable=True.

PySpark only

I came across this post when looking to do the same in PySpark. The easiest way is to just add the parameter ascending=False:

df.orderBy("col1", ascending=False).show(10)

Reference: http://spark.apache.org/docs/2.1.0/api/python/pyspark.sql.html#pyspark.sql.DataFrame.orderBy

If your application needs to handle money values up to a trillion then this should work: 13,2 If you need to comply with GAAP (Generally Accepted Accounting Principles) then use: 13,4

Usually you should sum your money values at 13,4 before rounding of the output to 13,2.

Go to /var/log/ and run cat postgres.log Here you will find the reason for the failure of postgres. If it is a smart shut down then probably your icu4c version (C++ library for Unicode) is not proper which is linked with postgres. So run the following commands.

brew upgrade brew cleanup This should work ;)

Previous answers point out correctly that you can only do this with the standard JDK tools by converting the JKS file into PKCS #12 format first. If you're interested, I put together a compact utility to import OpenSSL-derived keys into a JKS-formatted keystore without having to convert the keystore to PKCS #12 first: http://commandlinefanatic.com/cgi-bin/showarticle.cgi?article=art049

You would use the linked utility like this:

$ openssl req -x509 -newkey rsa:2048 -keyout localhost.key -out localhost.csr -subj "/CN=localhost"

(sign the CSR, get back localhost.cer)

$ openssl rsa -in localhost.key -out localhost.rsa
Enter pass phrase for localhost.key:
writing RSA key
$ java -classpath . KeyImport -keyFile localhost.rsa -alias localhost -certificateFile localhost.cer -keystore localhost.jks -keystorePassword changeit -keystoreType JKS -keyPassword changeit

If you want to override values specified in your application.properties file, you can change your active profile while you run your application and create an application properties file for the profile. So, for example, let's specify the active profile "override" and then, assuming you have created your new application properties file called "application-override.properties" under /tmp, then you can run

java -jar yourApp.jar --spring.profiles.active="override" --spring.config.location="file:/tmp/,classpath:/" 

The values especified under spring.config.location are evaluated in reverse order. So, in my example, the classpat is evaluated first, then the file value.

If the jar file and the "application-override.properties" file are in the current directory you can actually simply use

java -jar yourApp.jar --spring.profiles.active="override"

since Spring Boot will find the properties file for you

check fnAddData: https://legacy.datatables.net/ref

$(document).ready(function () {
  var table = $('#example').dataTable();
  var url = '/RESTApplicationTest/webresources/entity.person';
  $.get(url, function (data) {
    for (var i = 0; i < data.length; i++) {
      table.fnAddData([data[i].idPerson, data[i].firstname, data[i].lastname, data[i].email, data[i].phone])
    }
  });
});

It works the same way for axes: parse(text='70^o*N') will raise the o as a superscript (the *N is to make sure the N doesn't get raised too).

labelsX=parse(text=paste(abs(seq(-100, -50, 10)), "^o ", "*W", sep=""))
labelsY=parse(text=paste(seq(50,100,10), "^o ", "*N", sep=""))
plot(-100:-50, 50:100, type="n", xlab="", ylab="", axes=FALSE)

Here's an example:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def self.up
    rename_table :old_table_name, :new_table_name
  end

  def self.down
    rename_table :new_table_name, :old_table_name
  end
end

I had to go and rename the model declaration file manually.

Edit:

In Rails 3.1 & 4, ActiveRecord::Migration::CommandRecorder knows how to reverse rename_table migrations, so you can do this:

class RenameOldTableToNewTable < ActiveRecord::Migration
  def change
    rename_table :old_table_name, :new_table_name
  end 
end

(You still have to go through and manually rename your files.)

I think this works:

$(document).ready(function(){

    // Hide (collapse) the toggle containers on load
    $(".toggle_container").hide();

    // Switch the "Open" and "Close" state per click then 
    // slide up/down (depending on open/close state)
    $("h2.trigger").click(function(){
        $(this).toggleClass("active").next().slideToggle("slow");
        return false; // Prevent the browser jump to the link anchor
    });
});

You can throw your own custom errors by extending the Exception class.

class CustomException : Exception {
    [string] $additionalData

    CustomException($Message, $additionalData) : base($Message) {
        $this.additionalData = $additionalData
    }
}

try {
    throw [CustomException]::new('Error message', 'Extra data')
} catch [CustomException] {
    # NOTE: To access your custom exception you must use $_.Exception
    Write-Output $_.Exception.additionalData

    # This will produce the error message: Didn't catch it the second time
    throw [CustomException]::new("Didn't catch it the second time", 'Extra data')
}

For int[] what you've done looks good to me. astander's answer would also work well for List<int>.

Yes.. It is possible using css

<a class="disable-me" href="page.html">page link</a>

.disable-me {
    pointer-events: none;
}

Lists represent a sequential ordering of elements. Maps are used to represent a collection of key / value pairs.

While you could use a map as a list, there are some definite downsides of doing so.

Maintaining order: - A list by definition is ordered. You add items and then you are able to iterate back through the list in the order that you inserted the items. When you add items to a HashMap, you are not guaranteed to retrieve the items in the same order you put them in. There are subclasses of HashMap like LinkedHashMap that will maintain the order, but in general order is not guaranteed with a Map.

Key/Value semantics: - The purpose of a map is to store items based on a key that can be used to retrieve the item at a later point. Similar functionality can only be achieved with a list in the limited case where the key happens to be the position in the list.

Code readability Consider the following examples.

    // Adding to a List
    list.add(myObject);         // adds to the end of the list
    map.put(myKey, myObject);   // sure, you can do this, but what is myKey?
    map.put("1", myObject);     // you could use the position as a key but why?

    // Iterating through the items
    for (Object o : myList)           // nice and easy
    for (Object o : myMap.values())   // more code and the order is not guaranteed

Collection functionality Some great utility functions are available for lists via the Collections class. For example ...

    // Randomize the list
    Collections.shuffle(myList);

    // Sort the list
    Collections.sort(myList, myComparator);  

Hope this helps,

Here is my gradle build script that executes strings stored in heredocs:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

You can use reorder:

qplot(reorder(factor(cyl),factor(cyl),length),data=mtcars,geom="bar")

Edit:

To have the tallest bar at the left, you have to use a bit of a kludge:

qplot(reorder(factor(cyl),factor(cyl),function(x) length(x)*-1),
   data=mtcars,geom="bar")

I would expect this to also have negative heights, but it doesn't, so it works!

Code to read CSV file and upload to table in database.

   $file = fopen($filename, "r");
            while (($getData = fgetcsv($file, 10000, ",")) !== FALSE) {

                $result = mysqli_query($conn, $sql);
                if (!isset($result)) {
                    echo "<script type=\"text/javascript\">
                            alert(\"Invalid File:Please Upload CSV File. 
                            window.location = \"home.do\"
                          </script>";
                } else {
                    echo "<script type=\"text/javascript\">

Had similar problem due to some CSV files that had various names for the same column.
This was the solution:

I wrote a function to return the first valid column name in a list, then used that...

# Return the string name of the first name in names that is a column name in tbl
# else null
ChooseCorrectColumnName <- function(tbl, names) {
for(n in names) {
    if (n %in% colnames(tbl)) {
        return(n)
    }
}
return(null)
}

then...

cptcodefieldname = ChooseCorrectColumnName(file, c("CPT", "CPT.Code"))
icdcodefieldname = ChooseCorrectColumnName(file, c("ICD.10.CM.Code", "ICD10.Code"))

if (is.null(cptcodefieldname) || is.null(icdcodefieldname)) {
        print("Bad file column name")
}

# Here we use the hash table implementation where 
# we have a string key and list value so we need actual strings,
# not Factors
file[cptcodefieldname] = as.character(file[cptcodefieldname])
file[icdcodefieldname] = as.character(file[icdcodefieldname])
for (i in 1:length(file[cptcodefieldname])) {
    cpt_valid_icds[file[cptcodefieldname][i]] <<- unique(c(cpt_valid_icds[[file[cptcodefieldname][i]]], file[icdcodefieldname][i]))
}

I know this question is old, but for the one's what are new, here is what you can do:

HTML

<img id="demo" src="myImage.png">

<button onclick="myFunction()">Click Me!</button>

JAVASCRIPT

function myFunction() {
document.getElementById('demo').src = "myImage.png";
}

I faced the issue even though JAVA_HOME was pointing to JDK. It took time to figure out why it was throwing the exception.

The issue was I set JAVA_HOME as admin user on my window machine. You need to add JAVA_HOME environment variable pointing to right JDK to your user profile environment variable settings.

I would not use .at for performance reasons.

Define a struct:

//#pragma pack(push, 2) //not useful (see comments below)
struct RGB {
    uchar blue;
    uchar green;
    uchar red;  };

And then use it like this on your cv::Mat image:

RGB& rgb = image.ptr<RGB>(y)[x];

image.ptr(y) gives you a pointer to the scanline y. And iterate through the pixels with loops of x and y

Not append() but appends() So, right answer is:

{!! $records->appends(Input::except('page'))->links() !!}

your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if as a top-level step in declarative, so you need to wrap it in a script step. here's a working declarative version:

pipeline {
    agent any

    stages {
        stage('test') {
            steps {
                sh 'echo hello'
            }
        }
        stage('test1') {
            steps {
                sh 'echo $TEST'
            }
        }
        stage('test3') {
            steps {
                script {
                    if (env.BRANCH_NAME == 'master') {
                        echo 'I only execute on the master branch'
                    } else {
                        echo 'I execute elsewhere'
                    }
                }
            }
        }
    }
}

you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!

The + character has a special meaning in a URL => it means whitespace - . If you want to use the literal + sign, you need to URL encode it to %2b:

body=Hi+there%2bHello+there

Here's an example of how you could properly generate URLs in .NET:

var uriBuilder = new UriBuilder("https://mail.google.com/mail");

var values = HttpUtility.ParseQueryString(string.Empty);
values["view"] = "cm";
values["tf"] = "0";
values["to"] = "[email protected]";
values["su"] = "some subject";
values["body"] = "Hi there+Hello there";

uriBuilder.Query = values.ToString();

Console.WriteLine(uriBuilder.ToString());

The result

https://mail.google.com:443/mail?view=cm&tf=0&to=someemail%40somedomain.com&su=some+subject&body=Hi+there%2bHello+there

This works in IE without even having to declare a var for the table and will delete all rows:

for(var i = 0; i < resultsTable.rows.length;)
{   
   resultsTable.deleteRow(i);
}

Another option is to go with bokeh. IMO, it is a good alternative at least for real-time plots. Here is a bokeh version of the code in the question:

from bokeh.plotting import curdoc, figure
import random
import time

def update():
    global i
    temp_y = random.random()
    r.data_source.stream({'x': [i], 'y': [temp_y]})
    i += 1

i = 0
p = figure()
r = p.circle([], [])
curdoc().add_root(p)
curdoc().add_periodic_callback(update, 100)

and for running it:

pip3 install bokeh
bokeh serve --show test.py

bokeh shows the result in a web browser via websocket communications. It is especially useful when data is generated by remote headless server processes.

TypeScript 0.9+ has a specification for enums:

enum AnimationType {
    BOUNCE,
    DROP,
}

The final comma is optional.

If the data is populated from the database, you might consider not using an <input> tag to display it. Nevertheless, you can disable it right in the tag:

<input type='text' value='${magic.database.value}' disabled>

If you need to disable it with Javascript later, you can set the "disabled" attribute:

document.getElementById('theInput').disabled = true;

The reason I suggest not showing the value as an <input> is that, in my experience, it causes layout issues. If the text is long, then in an <input> the user will need to try and scroll the text, which is not something normal people would guess to do. If you just drop it into a <span> or something, you have more styling flexibility.

One quick way to do this is to create a column with a formula that evaluates to true for the rows you care about and then filter for the value TRUE in that column.

You are just missing to make it raw. The issue is with "\". Adding r before the path would do the work :)

import os
os.system(r"D:\xxx1\xxx2XMLnew\otr.bat")

With Laravel 5.6, if you want pass multiple emails with names, you need to pass array of associative arrays. Example pushing multiple recipients into the $to array:

$to[] = array('email' => $email, 'name' => $name);

Fixed two recipients:

$to = [['email' => '[email protected]', 'name' => 'User One'], 
       ['email' => '[email protected]', 'name' => 'User Two']];

The 'name' key is not mandatory. You can set it to 'name' => NULL or do not add to the associative array, then only 'email' will be used.

Here is a pure python method for simple strings, left here for posterity.

def string2bits(s=''):
    return [bin(ord(x))[2:].zfill(8) for x in s]

def bits2string(b=None):
    return ''.join([chr(int(x, 2)) for x in b])

s = 'Hello, World!'
b = string2bits(s)
s2 = bits2string(b)

print 'String:'
print s

print '\nList of Bits:'
for x in b:
    print x

print '\nString:'
print s2

String:
Hello, World!

List of Bits:
01001000
01100101
01101100
01101100
01101111
00101100

01101111
01110010

Just provide another implementation of Jason's answer by C.

After discussing with my classmates, based on Jason's explanation, I like the recursive version more if you don't care about the performance very much:

For example:

#include<stdio.h>

int mypow( int base, int pow, int mod ){
    if( pow == 0 ) return 1;
    if( pow % 2 == 0 ){
        int tmp = mypow( base, pow >> 1, mod );
        return tmp * tmp % mod;
    }
    else{
        return base * mypow( base, pow - 1, mod ) % mod;
    }
}

int main(){
    printf("%d", mypow(5,55,221));
    return 0;
}

Yes you can change it. but in api 22 and above, using NotificationCompat.Builder and setColorized(true) :

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context, context.getPackageName())
                .setContentTitle(title)
                .setContentText(message)
                .setSmallIcon(icon, level)
                .setLargeIcon(largeIcon)
                .setContentIntent(intent)
                .setColorized(true)
                .setDefaults(0)
                .setCategory(Notification.CATEGORY_SERVICE)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setPriority(NotificationCompat.PRIORITY_HIGH);

You can't access a MySQL DB from Android natively. EDIT: Actually you may be able to use JDBC, but it is not recommended (or may not work?) ... see Android JDBC not working: ClassNotFoundException on driver

For most [good] users this might be fine. But imagine you get a hacker that gets a hold of your program. I've decompiled my own applications and its scary what I've seen. What if they get your username / password to your database and wreak havoc? Bad.

Asked by many, The childs in list must not have width "match_parent" if you are looking for listview click only.

Even if you set the "Focusable" to false it wont work. Set the child's Width to wrap_content

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ...

On OS X Synalyze It! lets you display parts of your file in different encodings (all which are supported by the ICU library). Once you know what's the source encoding you can copy the whole file (bytes) via clipboard and insert into a new document where the target encoding (UTF-8 or whatever you like) is selected.

Very helpful when working with UTF-8 or other Unicode representations is UnicodeChecker

There are methods like WriteAllText in the File class for common operations on files.

Use the MapPath method to get the physical path for a file in your web application.

File.WriteAllText(Server.MapPath("~/data.txt"), TextBox1.Text);

Per Byron's answer, you can't set networkaddress.cache.ttl or networkaddress.cache.negative.ttl as System Properties by using the -D flag or calling System.setProperty because these are not System properties - they are Security properties.

If you want to use a System property to trigger this behavior (so you can use the -D flag or call System.setProperty), you will want to set the following System property:

-Dsun.net.inetaddr.ttl=0

This system property will enable the desired effect.

But be aware: if you don't use the -D flag when starting the JVM process and elect to call this from code instead:

java.security.Security.setProperty("networkaddress.cache.ttl" , "0")

This code must execute before any other code in the JVM attempts to perform networking operations.

This is important because, for example, if you called Security.setProperty in a .war file and deployed that .war to Tomcat, this wouldn't work: Tomcat uses the Java networking stack to initialize itself much earlier than your .war's code is executed. Because of this 'race condition', it is usually more convenient to use the -D flag when starting the JVM process.

If you don't use -Dsun.net.inetaddr.ttl=0 or call Security.setProperty, you will need to edit $JRE_HOME/lib/security/java.security and set those security properties in that file, e.g.

networkaddress.cache.ttl = 0
networkaddress.cache.negative.ttl = 0

But pay attention to the security warnings in the comments surrounding those properties. Only do this if you are reasonably confident that you are not susceptible to DNS spoofing attacks.

Use the ArrayList copy constructor, then sort that.

List oldList;
List newList = new ArrayList(oldList);
Collections.sort(newList);

After making the copy, any changes to newList do not affect oldList.

Note however that only the references are copied, so the two lists share the same objects, so changes made to elements of one list affect the elements of the other.

It is easy to check for removable devices. However, there's no guarantee that it is a USB device:

var drives = DriveInfo.GetDrives()
    .Where(drive => drive.IsReady && drive.DriveType == DriveType.Removable);

This will return a list of all removable devices that are currently accessible. More information:

• The DriveType enumeration (msdn documentation)

What @VonC says is correct, but you can put the commands to set debug directly into VM arguments on jBoss Launch.

To do that, open jBoss server inside Eclipse, go to Open launch configuration and put this in VM arguments textbox: vm args

import json
data = json.load(open('/Users/laxmanjeergal/Desktop/json.json'))
jtopy=json.dumps(data) #json.dumps take a dictionary as input and returns a string as output.
dict_json=json.loads(jtopy) # json.loads take a string as input and returns a dictionary as output.
print(dict_json["shipments"])

The following code worked for me:

echo userInput

Make sure you include the = sign in addition to passing the arguments to the function. I.E.

=SUM(A1:A3) //this would give you the sum of cells A1, A2, and A3.

 @foreach (var m in Model)
    {
      <img src="~/Images/@m.Url" style="overflow: hidden; position: relative; width:200px; height:200px;" />
    }

A simple solution would be to iterate through the Controls list in a foreach loop. Something like this:

foreach (Control child in Controls)
{
    // Code that executes for each control.
}

So now you have your iterator, child, which is of type Control. Now do what you will with that, personally I found this in a project I did a while ago in which it added an event for this control, like this:

child.MouseDown += new MouseEventHandler(dragDown);

If you use ReSharper, you can quickly generate constructors by typing:

• 'ctor' + Tab + Tab (without parameters),
• 'ctorf' + Tab + Tab (with parameters that initialize all fields) or
• 'ctorp' + Tab + Tab (with parameters that initialize all properties).

In C++11

for (auto i = path.begin(); i != path.end(); ++i)
std::cout << *i << ' ';

for(int i=0; i<path.size(); ++i)
std::cout << path[i] << ' ';

Use below bash command to locate all virtual env in your system. You can modify the command according to your need to get in your desired format.

locate --regex "bin/activate"$ | sed 's/bin\/activate$//'

To sort by MULTIPLE COLUMN (Sort by column_1, and then sort by column_2)

with open('unsorted.csv',newline='') as csvfile:
    spamreader = csv.DictReader(csvfile, delimiter=";")
    sortedlist = sorted(spamreader, key=lambda row:(row['column_1'],row['column_2']), reverse=False)


with open('sorted.csv', 'w') as f:
    fieldnames = ['column_1', 'column_2', column_3]
    writer = csv.DictWriter(f, fieldnames=fieldnames)
    writer.writeheader()
    for row in sortedlist:
        writer.writerow(row)

Found a good solution what worked for me, check this link https://codepen.io/chriswrightdesign/pen/emQNGZ/?editors=1100 First, we add a parent div, second we change min-height:100% to min-height:100vh. It works like a charm.

// by having a parent with flex-direction:row, 
// the min-height bug in IE doesn't stick around.
.flashy-content-outer { 
    display:flex;
    flex-direction:row;
}
.flashy-content-inner {
    display:flex;
    flex-direction:column;
    justify-content:center;
    align-items:center;
    min-width:100vw;
    min-height:100vh;
    padding:20px;
    box-sizing:border-box;
}
.flashy-content {
    display:inline-block;
    padding:15px;
    background:#fff;
}  

Update 2018

There is no need for extra CSS, and there are multiple centering methods in Bootstrap 4:

• text-center for center display:inline elements
• mx-auto for centering display:block elements inside display:flex (d-flex)
• offset-* or mx-auto can be used to center grid columns
• or justify-content-center on row to center grid columns

mx-auto (auto x-axis margins) will center inside display:flex elements that have a defined width, (%, vw, px, etc..). Flexbox is used by default on grid columns, so there are also various centering methods.

In your case, you can simply mx-auto to the cards.

I know this is an old question but you can use:

array_push($data, array($category => $question));

This will push the array onto the end of your current array. Or if you are just trying to add single values to the end of your array, not more arrays then you can use this:

array_push($data,$question);

It is useful to think of MIME in the context of the client-server model. Clients and servers communicate over what is known as the HTTP protocol. In a http request or response, we can have a body. The Content-type or MIME type specifies what is the type of the body, like text/javascript or something else like audio, video, etc.

However, MIME types are not limited just to HTTP.

As the name suggests, MIME stands for Multipurpose Internet Mail Extensions. Originally, SMTP only supported ascii-encodings. However, there as a need for more. We could use MIME to slap a label on the content being transmitted or received.

While probably not any better than your solution, you could adjust your T-SQL to return the same result using COALESCE:

SELECT MyField = COALESCE(table.MyField, " NA")

The reasoning for the extra space before the NA is to allow sorting to place the NA results at the top. Since your data may vary, that may not be a great option.

declare @float as float(10)
declare @Decimal as decimal(10)
declare @Inetger as int

set @float =10.7
set @Decimal =10.7
set @Inetger=@Decimal

print @Inetger

in float when set value to integer print 10 but in decimal 11

Well it depends on your OS - actually I did not test it on MS Windows - but Conque is one of the best plugins out there.

Actually, it can be better, but works.

Pass a header name to this function to get its value without using for loop. Returns null if header not found.

/**
 * @var string $headerName case insensitive header name
 *
 * @return string|null header value or null if not found
 */
function get_header($headerName)
{
    $headers = getallheaders();
    return isset($headerName) ? $headers[$headerName] : null;
}

Note: this works only with Apache server, see: http://php.net/manual/en/function.getallheaders.php

Note: this function will process and load all of the headers to the memory and it's less performant than a for loop.

As I understand, you want the average value for each id at each pass. The solution is

SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;

babel-polyfill allows you to use the full set of ES6 features beyond syntax changes. This includes features such as new built-in objects like Promises and WeakMap, as well as new static methods like Array.from or Object.assign.

Without babel-polyfill, babel only allows you to use features like arrow functions, destructuring, default arguments, and other syntax-specific features introduced in ES6.

I was facing a similar issue, I had a file on my project, and wanted to test a class which had to deal with loading files from the FS and process them some way. What I did was:

• added the file test.txt to my test project
• on the solution explorer hit alt-enter (file properties)
• there I set BuildAction to Content and Copy to Output Directory to Copy if newer, I guess Copy always would have done it as well

then on my tests I just had to Path.Combine(Environment.CurrentDirectory, "test.txt") and that's it. Whenever the project is compiled it will copy the file (and all it's parent path, in case it was in, say, a folder) to the bin\Debug (or whatever configuration you are using) folder.

Hopes this helps someone

In Python, functions are first-class objects, this means: function references can be passed in inputs to other functions and/or methods, and executed from inside them.

Instances of Classes (aka Objects), can be treated as if they were functions: pass them to other methods/functions and call them. In order to achieve this, the __call__ class function has to be specialized.

def __call__(self, [args ...]) It takes as an input a variable number of arguments. Assuming x being an instance of the Class X, x.__call__(1, 2) is analogous to calling x(1,2) or the instance itself as a function.

In Python, __init__() is properly defined as Class Constructor (as well as __del__() is the Class Destructor). Therefore, there is a net distinction between __init__() and __call__(): the first builds an instance of Class up, the second makes such instance callable as a function would be without impacting the lifecycle of the object itself (i.e. __call__ does not impact the construction/destruction lifecycle) but it can modify its internal state (as shown below).

Example.

class Stuff(object):

    def __init__(self, x, y, range):
        super(Stuff, self).__init__()
        self.x = x
        self.y = y
        self.range = range

    def __call__(self, x, y):
        self.x = x
        self.y = y
        print '__call__ with (%d,%d)' % (self.x, self.y)

    def __del__(self):
        del self.x
        del self.y
        del self.range

>>> s = Stuff(1, 2, 3)
>>> s.x
1
>>> s(7, 8)
__call__ with (7,8)
>>> s.x
7

JavaScript does require semicolons, it's just that the interpreter will insert them for you on line breaks where possible^*.

Unfortunately, the code

var a = new B(args)(stuff)()

does not result in a syntax error, so no ; will be inserted. (An example which can run is

var answer = new Function("x", "return x")(function(){return 42;})();

To avoid surprises like this, train yourself to always end a statement with ;.

Use:

find . ! -readable -prune -o -print

or more generally

find <paths> ! -readable -prune -o <other conditions like -name> -print

• to avoid "Permission denied"
• AND do NOT suppress (other) error messages
• AND get exit status 0 ("all files are processed successfully")

Works with: find (GNU findutils) 4.4.2. Background:

• The -readable test matches readable files. The ! operator returns true, when test is false. And ! -readable matches not readable directories (&files).
• The -prune action does not descend into directory.
• ! -readable -prune can be translated to: if directory is not readable, do not descend into it.
• The -readable test takes into account access control lists and other permissions artefacts which the -perm test ignores.

See also find(1) manpage for many more details.

Best answer doesn't work for me. I needed ssh:// from the beggining.

# does not work
git remote set-url origin [email protected]:10000/aaa/bbbb/ccc.git
# work
git remote set-url origin ssh://[email protected]:10000/aaa/bbbb/ccc.git

If you need two variables in the XML, you can use:

%1$d text... %2$d or %1$s text... %2$s for string variables.

Example :

strings.xml

<string name="notyet">Website %1$s isn\'t yet available, I\'m working on it, please wait %2$s more days</string>

activity.java

String site = "site.tld";
String days = "11";

//Toast example
String notyet = getString(R.string.notyet, site, days);
Toast.makeText(getApplicationContext(), notyet, Toast.LENGTH_LONG).show();

The answer above worked fine (MVC5 + Bootstrap 3.0), but the height returned to the default once the navbar button showed up (very small screen). Had to add the below in my .css to fix that as well.

.navbar-header .navbar-toggle {
    margin-top:0px;
    margin-bottom:0px;
    padding-bottom:0px;
}

A simple approach instead of using JSON.parse

 success: function(response){
     var resdata = response;
     alert(resdata['name']);
}

just enter this line in the command line :

set RANDFILE=.rnd

Short answer: You can't.

CSS does not have techniques which affect the rendering of fonts in the browser; only the system can do that.

Obviously, text sharpness can easily be achieved with pixel-dense screens, but if you're using a normal PC that's gonna be hard to achieve.

There are some newer fonts that are smooth but at the sacrifice of it appearing somewhat blurry (look at most of Adobe's fonts, for example). You can also find some smooth-but-blurry-by-design fonts at Google Fonts, however.

There are some new CSS3 techniques for font rendering and text effects though the consistency, performance, and reliability of these techniques vary so largely to the point where you generally shouldn't rely on them too much.

On a default instance, SQL Server listens on TCP/1433 by default. This can be changed. On a named instance, unless configured differently, SQL Server listens on a dynamic TCP port. What that means is should SQL Server discover that the port is in use, it will pick another TCP port. How clients usually find the right port in the case of a named instance is by talking to the SQL Server Listener Service/SQL Browser. That listens on UDP/1434 and cannot be changed. If you have a named instance, you can configure a static port and if you have a need to use Kerberos authentication/delegation, you should.

What you'll need to determine is what port your SQL Server is listening on. Then you'll need to get with your networking/security folks to determine if they allow communication to that port via VPN. If they are, as indicated, check your firewall settings. Some systems have multiple firewalls (my laptop is an example). If so, you'll need to check all the firewalls on your system.

If all of those are correct, verify the server doesn't have an IPSEC policy that restricts access to the SQL Server port via IP address. That also could result in you being blocked.

As in the answer of Escobar Ceaser, I suggest to use quotes arround the whole path. It's the common way to wrap the whole path in "", not only separate directory names within the path.

I had a similar issue that it didn't work for me. But it was no option to use "" within the path for separate directory names because the path contained environment variables, which theirself cover more than one directory hierarchies. The conclusion was that I missed the space between the closing " and the (

The correct version, with the space before the bracket, would be

If NOT exist "C:\Documents and Settings\John\Start Menu\Programs\Software Folder" (
 start "\\filer\repo\lab\software\myapp\setup.exe"
 pause
) 

It sounds like perhaps the class is not the UITableViewDelegate for that table view, though UITableViewController is supposed to set that automatically.

Any chance you reset the delegate to some other class?

This is very good discussion. I had one of those moments when I wished or lets say hoped (successfully that I might add) to reinvent the wheel be it a square one. Any ways above is good discussion, so any one coming here looking for what is the difference between Element property and attribute. here is my penny worth and I did have to find it out hard way. I would keep it simple so no extraordinary tech jargon.

suppose we have a variable calls 'A'. what we are used to is as following.

Below will throw an error because simply it put its is kind of object that can only have one property and that is singular left hand side = singular right hand side object. Every thing else is ignored and tossed out in bin.

let A = 'f';
A.b =2;
console.log(A.b);

who has decided that it has to be singular = singular. People who make JavaScript and html standards and thats how engines work.

Lets change the example.

let A = {};
A.b =2;
console.log(A.b);

This time it works ..... because we have explicitly told it so and who decided we can tell it in this case but not in previous case. Again people who make JavaScript and html standards.

I hope we are on this lets complicate it further

let A = {};
A.attribute ={};
A.attribute.b=5;
console.log(A.attribute.b); // will work

console.log(A.b); // will not work

What we have done is tree of sorts level 1 then sub levels of non-singular object. Unless you know what is where and and call it so it will work else no.

This is what goes on with HTMLDOM when its parsed and painted a DOm tree is created for each and every HTML ELEMENT. Each has level of properties per say. Some are predefined and some are not. This is where ID and VALUE bits come on. Behind the scene they are mapped on 1:1 between level 1 property and sun level property aka attributes. Thus changing one changes the other. This is were object getter ans setter scheme of things plays role.

let A = {
attribute :{
id:'',
value:''
},
getAttributes: function (n) {
    return this.attribute[n];
  },
setAttributes: function (n,nn){
this.attribute[n] = nn;
if(this[n]) this[n] = nn;
},
id:'',
value:''
};



A.id = 5;
console.log(A.id);
console.log(A.getAttributes('id'));

A.setAttributes('id',7)
console.log(A.id);
console.log(A.getAttributes('id'));

A.setAttributes('ids',7)
console.log(A.ids);
console.log(A.getAttributes('ids'));

A.idsss=7;
console.log(A.idsss);
console.log(A.getAttributes('idsss'));

This is the point as shown above ELEMENTS has another set of so called property list attributes and it has its own main properties. there some predefined properties between the two and are mapped as 1:1 e.g. ID is common to every one but value is not nor is src. when the parser reaches that point it simply pulls up dictionary as to what to when such and such are present.

All elements have properties and attributes and some of the items between them are common. What is common in one is not common in another.

In old days of HTML3 and what not we worked with html first then on to JS. Now days its other way around and so has using inline onlclick become such an abomination. Things have moved forward in HTML5 where there are many property lists accessible as collection e.g. class, style. In old days color was a property now that is moved to css for handling is no longer valid attribute.

Element.attributes is sub property list with in Element property.

Unless you could change the getter and setter of Element property which is almost high unlikely as it would break hell on all functionality is usually not writable off the bat just because we defined something as A.item does not necessarily mean Js engine will also run another line of function to add it into Element.attributes.item.

I hope this gives some headway clarification as to what is what. Just for the sake of this I tried Element.prototype.setAttribute with custom function it just broke loose whole thing all together, as it overrode native bunch of functions that set attribute function was playing behind the scene.

@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

For those using npm to install packages, you can install jquery via npm install jquery and then use elixir to compile jquery and your other npm packages into one file (e.g. vendor.js). Here's a sample gulpfile.js

var elixir = require('laravel-elixir');

elixir(function(mix) {
    mix

    .scripts([
        'jquery/dist/jquery.min.js',
        // list your other npm packages here
    ],
    'public/js/vendor.js', // 2nd param is the output file
    'node_modules')        // 3rd param is saying "look in /node_modules/ for these scripts"

    .scripts([
        'scripts.js'       // your custom js file located in default location: /resources/assets/js/
    ], 'public/js/app.js') // looks in default location since there's no 3rd param

    .version([             // optionally append versioning string to filename
        'js/vendor.js',    // compiled files will be in /public/build/js/
        'js/app.js'
    ]);

});

Convenience method for implementing @Pangea's answer:

/*
*  Convenience method to add a specified number of minutes to a Date object
*  From: http://stackoverflow.com/questions/9043981/how-to-add-minutes-to-my-date
*  @param  minutes  The number of minutes to add
*  @param  beforeTime  The time that will have minutes added to it
*  @return  A date object with the specified number of minutes added to it 
*/
private static Date addMinutesToDate(int minutes, Date beforeTime){
    final long ONE_MINUTE_IN_MILLIS = 60000;//millisecs

    long curTimeInMs = beforeTime.getTime();
    Date afterAddingMins = new Date(curTimeInMs + (minutes * ONE_MINUTE_IN_MILLIS));
    return afterAddingMins;
}

Basically, you can't run it from a UNC path without seeing that message.

What I usually do is just put a CLS at the top of the script so I don't have to see that message. Then, specify the full path to files in the network share that you need to use.

Paths under linux are separated by colons (:), not semi-colons (;), as theatrus correctly used it in his example. I believe Java respects this convention.

Edit

Alternatively to what andy suggested, you may use the following form (which sets CLASSPATH for the duration of the command):

CLASSPATH=".:../somejar.jar:../mysql-connector-java-5.1.6-bin.jar" java -Xmx500m ...

whichever is more convenient to you.

There might be another solution to this:
Your code was:

geom_point(aes(..., show.legend = FALSE))

You can specify the show.legend parameter after the aes call:

geom_point(aes(...), show.legend = FALSE)

then the corresponding legend should disappear

There is a subtle difference between running FOR from the command line and from a batch file. In a batch file, you need to put two % characters in front of each variable reference.

From a command line:

FOR %i IN (*) DO ECHO %i

From a batch file:

FOR %%i IN (*) DO ECHO %%i

Better yet, use JodaTime. Much easier to parse strings and into strings. Is thread safe as well. Worth the time it will take you to implement it.

new Date().toISOString()
"2016-02-18T23:59:48.039Z"
new Date().toISOString().split('T')[0];
"2016-02-18"
new Date().toISOString().replace('-', '/').split('T')[0].replace('-', '/');
"2016/02/18"

new Date().toLocaleString().split(',')[0]
"2/18/2016"

I use ajaxcontrol toolkit's AutoComplete

A key currently still is not required ("required" in the meaning "it will not work without"), but I think there is a good reason for the warning.

But in the documentation you may read now : "All JavaScript API applications require authentication."

I'm sure that it's planned for the future , that Javascript API Applications will not work without a key(as it has been in V2).

You better use a key when you want to be sure that your application will still work in 1 or 2 years.

You get this error if you have constrained T to being a class

The best solution is to keep multiple Views in a Single View / View Group and then keep that one view in the SrcollView. ie.

Format -

<ScrollView> 
  <Another View>
       <RecyclerView>
       <TextView>
       <And Other Views>
  </Another View>
</ScrollView>

Eg.

<ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView

You can use a Stream for this, but instead of appending query parameters myself I'd use a Uri.Builder. For example:

final Map<String, String> map = new HashMap<>();
map.put("param1", "cat");
map.put("param2", "12");

final Uri uri = 
    map.entrySet().stream().collect(
        () -> Uri.parse("relativeUrl").buildUpon(),
        (builder, e) -> builder.appendQueryParameter(e.getKey(), e.getValue()),
        (b1, b2) -> { throw new UnsupportedOperationException(); }
    ).build();

//Or, if you consider it more readable...
final Uri.Builder builder = Uri.parse("relativeUrl").buildUpon();
map.entrySet().forEach(e -> builder.appendQueryParameter(e.getKey(), e.getValue())
final Uri uri = builder.build();

//...    

assertEquals(Uri.parse("relativeUrl?param1=cat&param2=12"), uri);

SQL Server doesn't have regular expressions. It uses the LIKE pattern matching syntax which isn't the same.

As it happens, you are close. Just need leading+trailing wildcards and move the NOT

 WHERE whatever NOT LIKE '%[a-z0-9]%'

I was stripping out single quotes so a telephone number column such as +1-800-123-4567 didn't result in a computation and yielding a negative number. I attempted a hack to remove them on empty cells, bar the quote, then hit this issue too (column F). It's far easier to just call text on the source cell and voila!:

=IF(F2="'","",TEXT(F2,""))

Once you set your Global Jenkins credentials, you can apply this step:

stage('Update GIT') {
  steps {
    script {
      catchError(buildResult: 'SUCCESS', stageResult: 'FAILURE') {
        withCredentials([usernamePassword(credentialsId: 'example-secure', passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME')]) {
            def encodedPassword = URLEncoder.encode("$GIT_PASSWORD",'UTF-8')
            sh "git config user.email [email protected]"
            sh "git config user.name example"
            sh "git add ."
            sh "git commit -m 'Triggered Build: ${env.BUILD_NUMBER}'"
            sh "git push https://${GIT_USERNAME}:${encodedPassword}@github.com/${GIT_USERNAME}/example.git"
        }
      }
    }
  }
}

You can achive this with creating new array:

<?php
$array = array(1 => "Toyota", 2 => "Nissan", 3 => "BMW");

if (isset ($_POST['search'])) {
  $maker = mysql_real_escape_string($_POST['Make']);
  echo $array[$maker];
}
?>

If someone need to preserve dots in extracted numbers:

var some = '65,87 EUR';
var number = some.replace(",",".").replace(/[^0-9&.]/g,'');
console.log(number); // returns 65.87

The following query is very helpful

select  * from
(select count(*) used from pg_stat_activity) q1,
(select setting::int res_for_super from pg_settings where name=$$superuser_reserved_connections$$) q2,
(select setting::int max_conn from pg_settings where name=$$max_connections$$) q3;

Source: java-implementation-of-rubys-gsub

Usage:

// Rewrite an ancient unit of length in SI units.
String result = new Rewriter("([0-9]+(\\.[0-9]+)?)[- ]?(inch(es)?)") {
    public String replacement() {
        float inches = Float.parseFloat(group(1));
        return Float.toString(2.54f * inches) + " cm";
    }
}.rewrite("a 17 inch display");
System.out.println(result);

// The "Searching and Replacing with Non-Constant Values Using a
// Regular Expression" example from the Java Almanac.
result = new Rewriter("([a-zA-Z]+[0-9]+)") {
    public String replacement() {
        return group(1).toUpperCase();
    }
}.rewrite("ab12 cd efg34");
System.out.println(result);

Implementation (redesigned):

import static java.lang.String.format;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public abstract class Rewriter {
    private Pattern pattern;
    private Matcher matcher;

    public Rewriter(String regularExpression) {
        this.pattern = Pattern.compile(regularExpression);
    }

    public String group(int i) {
        return matcher.group(i);
    }

    public abstract String replacement() throws Exception;

    public String rewrite(CharSequence original) {
        return rewrite(original, new StringBuffer(original.length())).toString();
    }

    public StringBuffer rewrite(CharSequence original, StringBuffer destination) {
        try {
            this.matcher = pattern.matcher(original);
            while (matcher.find()) {
                matcher.appendReplacement(destination, "");
                destination.append(replacement());
            }
            matcher.appendTail(destination);
            return destination;
        } catch (Exception e) {
            throw new RuntimeException("Cannot rewrite " + toString(), e);
        }
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(pattern.pattern());
        for (int i = 0; i <= matcher.groupCount(); i++)
            sb.append(format("\n\t(%s) - %s", i, group(i)));
        return sb.toString();
    }
}

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

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

I had a similar problem in spring tool suite(sts). THE .m2 repository was not completely downloaded in the local system which is the reason why I was getting this error. So I reinstalled sts and deleted the old .m2 repository from the system and created a new maven project in sts which downloaded the complete .m2 repository. It worked for me.

Because the question is not always supposed to be understood as the fastest technical way - I always suggest the most straightforward fastest way to understand/write: a list comprehension, one-liner

[i for i in list_from_which_to_search if i in list_to_search_in]

I had a list_to_search_in with all the items, and wanted to return the indexes of the items in the list_from_which_to_search.

This returns the indexes in a nice list.

There are other ways to check this problem - however list comprehensions are quick enough, adding to the fact of writing it quick enough, to solve a problem.

I have used wire shark tool for monitoring service calls from silver light app in browser to service. try the link gives clear info

It enables you to monitor the whole request and response contents.
