It's a general comparison operator. It returns either a -1, 0, or +1 depending on whether its receiver is less than, equal to, or greater than its argument.

The <=> ("Spaceship") operator will offer combined comparison in that it will :

Return 0 if values on either side are equal
Return 1 if the value on the left is greater
Return -1 if the value on the right is greater

The rules used by the combined comparison operator are the same as the currently used comparison operators by PHP viz. <, <=, ==, >= and >. Those who are from Perl or Ruby programming background may already be familiar with this new operator proposed for PHP7.

   //Comparing Integers

    echo 1 <=> 1; //output  0
    echo 3 <=> 4; //output -1
    echo 4 <=> 3; //output  1

    //String Comparison

    echo "x" <=> "x"; //output  0
    echo "x" <=> "y"; //output -1
    echo "y" <=> "x"; //output  1

yes! well to position a background image as though 0px from the right-hand side of the browser instead of the left - i use:

background-position: 100% 0px;

Try using the ArrayIntList from the apache framework. It works exactly like an arraylist, except it can hold primitive int.

From java specification :

The floating-point types are float and double, which are conceptually associated with the single-precision 32-bit and double-precision 64-bit format IEEE 754 values and operations as specified in IEEE Standard for Binary Floating-Point Arithmetic, ANSI/IEEE Standard 754-1985 (IEEE, New York).

As it's hard to do anything with numbers without understanding IEEE754 basics, here's another link.

It's important to understand that the precision isn't uniform and that this isn't an exact storage of the numbers as is done for integers.

An example :

double a = 0.3 - 0.1;
System.out.println(a);          

prints

0.19999999999999998

If you need arbitrary precision (for example for financial purposes) you may need Big Decimal.

"react-router-dom": "^4.2.2"

url like

BrowserHistory: http://localhost:3000/demo-7/detail/2?sort=name

HashHistory: http://localhost:3000/demo-7/#/detail/2?sort=name

with query-string dependency:

this.id = props.match.params.id;
this.searchObj = queryString.parse(props.location.search);
this.from = props.location.state.from;

console.log(this.id, this.searchObj, this.from);

results:

"react-router": "^2.4.1"

Url like http://localhost:8080/react-router01/1?name=novaline&age=26

const queryParams = this.props.location.query;

queryParams is a object contains the query params: {name: novaline, age: 26}

Though I found Gabriel answer to work to a degree i did find the following when trying to order the list vertically (first ul A-D and second ul E-G):

• When the ul had an even number of li's in it, it was not evenly spreading it across the ul's
• using the data-column in the ul didn't seem to work very well, I had to put 4 for 3 columns and even then it was still only spreading the li's into 2 of the ul generated by the JS

I have revised the JQuery so the above hopefully doesn't happen.

(function ($) {
    var initialContainer = $('.customcolumns'),
        columnItems = $('.customcolumns li'),
        columns = null,
        column = 0;
    function updateColumns() {
        column = 0;
        columnItems.each(function (idx, el) {
            if ($(columns.get(column)).find('li').length >= (columnItems.length / initialContainer.data('columns'))) {
                column += 1;
            }
            $(columns.get(column)).append(el);
        });
    }
    function setupColumns() {
        columnItems.detach();
        while (column++ < initialContainer.data('columns')) {
            initialContainer.clone().insertBefore(initialContainer);
            column++;
        }
        columns = $('.customcolumns');
        updateColumns();
    }

    $(setupColumns);
})(jQuery);

or

du -d1 is perhaps the shortest option. (As long as you don't need to pipe the input to another command.)

Adding to @gojomo you could use :after pseudo element for the additional element. The only caveat is that you'll need to define your innerText in a data-text attribute since CSS has limited content functions.

s {_x000D_
  color: red;_x000D_
  text-align: -1000em;_x000D_
  overflow: hidden;_x000D_
}_x000D_
s:after {_x000D_
  color: black;_x000D_
  content: attr(data-text);_x000D_
}

<s data-text="Strikethrough">Strikethrough</s>

If your databaseName value is correct, then use this: DriverManger.getconnection("jdbc:sqlserver://ServerIp:1433;user=myuser;password=mypassword;databaseName=databaseName;")

It turns out Microsoft already has this covered in its testing framework: CollectionAssert.AreEquivalent

Remarks

Two collections are equivalent if they have the same elements in the same quantity, but in any order. Elements are equal if their values are equal, not if they refer to the same object.

Using reflector, I modified the code behind AreEquivalent() to create a corresponding equality comparer. It is more complete than existing answers, since it takes nulls into account, implements IEqualityComparer and has some efficiency and edge case checks. plus, it's Microsoft :)

public class MultiSetComparer<T> : IEqualityComparer<IEnumerable<T>>
{
    private readonly IEqualityComparer<T> m_comparer;
    public MultiSetComparer(IEqualityComparer<T> comparer = null)
    {
        m_comparer = comparer ?? EqualityComparer<T>.Default;
    }

    public bool Equals(IEnumerable<T> first, IEnumerable<T> second)
    {
        if (first == null)
            return second == null;

        if (second == null)
            return false;

        if (ReferenceEquals(first, second))
            return true;

        if (first is ICollection<T> firstCollection && second is ICollection<T> secondCollection)
        {
            if (firstCollection.Count != secondCollection.Count)
                return false;

            if (firstCollection.Count == 0)
                return true;
        }

        return !HaveMismatchedElement(first, second);
    }

    private bool HaveMismatchedElement(IEnumerable<T> first, IEnumerable<T> second)
    {
        int firstNullCount;
        int secondNullCount;

        var firstElementCounts = GetElementCounts(first, out firstNullCount);
        var secondElementCounts = GetElementCounts(second, out secondNullCount);

        if (firstNullCount != secondNullCount || firstElementCounts.Count != secondElementCounts.Count)
            return true;

        foreach (var kvp in firstElementCounts)
        {
            var firstElementCount = kvp.Value;
            int secondElementCount;
            secondElementCounts.TryGetValue(kvp.Key, out secondElementCount);

            if (firstElementCount != secondElementCount)
                return true;
        }

        return false;
    }

    private Dictionary<T, int> GetElementCounts(IEnumerable<T> enumerable, out int nullCount)
    {
        var dictionary = new Dictionary<T, int>(m_comparer);
        nullCount = 0;

        foreach (T element in enumerable)
        {
            if (element == null)
            {
                nullCount++;
            }
            else
            {
                int num;
                dictionary.TryGetValue(element, out num);
                num++;
                dictionary[element] = num;
            }
        }

        return dictionary;
    }

    public int GetHashCode(IEnumerable<T> enumerable)
    {
        if (enumerable == null) throw new 
            ArgumentNullException(nameof(enumerable));

        int hash = 17;

        foreach (T val in enumerable)
            hash ^= (val == null ? 42 : m_comparer.GetHashCode(val));

        return hash;
    }
}

Sample usage:

var set = new HashSet<IEnumerable<int>>(new[] {new[]{1,2,3}}, new MultiSetComparer<int>());
Console.WriteLine(set.Contains(new [] {3,2,1})); //true
Console.WriteLine(set.Contains(new [] {1, 2, 3, 3})); //false

Or if you just want to compare two collections directly:

var comp = new MultiSetComparer<string>();
Console.WriteLine(comp.Equals(new[] {"a","b","c"}, new[] {"a","c","b"})); //true
Console.WriteLine(comp.Equals(new[] {"a","b","c"}, new[] {"a","b"})); //false

Finally, you can use your an equality comparer of your choice:

var strcomp = new MultiSetComparer<string>(StringComparer.OrdinalIgnoreCase);
Console.WriteLine(strcomp.Equals(new[] {"a", "b"}, new []{"B", "A"})); //true

A simple answer if you don't want to install anything new

To change all the fonts in your plot plot + theme(text=element_text(family="mono")) Where mono is your chosen font.

List of default font options:

• mono
• sans
• serif
• Courier
• Helvetica
• Times
• AvantGarde
• Bookman
• Helvetica-Narrow
• NewCenturySchoolbook
• Palatino
• URWGothic
• URWBookman
• NimbusMon
• URWHelvetica
• NimbusSan
• NimbusSanCond
• CenturySch
• URWPalladio
• URWTimes
• NimbusRom

R doesn't have great font coverage and, as Mike Wise points out, R uses different names for common fonts.

This page goes through the default fonts in detail.

I think what you are looking for is to keep the background image fixed and just move the content on scroll. For that you have to simply use the following css property :

background-attachment: fixed;

I usually start with something like:

set lines 256
set trimout on
set tab off

Have a look at help set if you have the help information installed. And then select name,address rather than select * if you really only want those two columns.

Try this:

if (items.elementAt(1) instanceof Double) {
   sum.add( i, items.elementAt(1));
}

You need to pass your context to your fyl class..
One solution is make a constructor like this for your fyl class:

public class fyl {
 Context mContext;
 public fyl(Context mContext) {
       this.mContext = mContext;
 }

 public Location getLocation() {
       --
       locationManager = (LocationManager)mContext.getSystemService(context);

       --
 }
}

So in your activity class create the object of fyl in onCreate function like this:

package com.atClass.lmt;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import android.location.Location;

public class lmt extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        fyl lfyl = new fyl(this); //Here the context is passing 

        Location location = lfyl.getLocation();
        String latLongString = lfyl.updateWithNewLocation(location);

        TextView myLocationText = (TextView)findViewById(R.id.myLocationText);
        myLocationText.setText("Your current position is:\n" + latLongString);
    }
}

Create a linked server to the source server. The easiest way is to right click "Linked Servers" in Management Studio; it's under Management -> Server Objects.

Then you can copy the table using a 4-part name, server.database.schema.table:

select  *
into    DbName.dbo.NewTable
from    LinkedServer.DbName.dbo.OldTable

This will both create the new table with the same structure as the original one and copy the data over.

I had the same issue. Turns out the reason was a few of my resources had capital letters in their filenames. I know it sounds trivial but just changing them to all small letters fixed it and retrieved my R.java file again.

Hope that helps.

Just copy the remote from the original git clone command (or from git remote -v). You will get something like this:

• Bitbucket: git+ssh://[email protected]:your_account/my_pro.git

• GitHub: git+ssh://[email protected]:your_account/my_pro.git

Next, you need to replace : with / next to the domain name.

So install using:

pip install git+ssh://[email protected]/your_account/my_pro.git

It is actually a permission issue. Add these lines in your platforms/android/AndroidManifest.xml file:

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

You can try this

netstat -vanp tcp | grep 3000

In order to remotely access a PostgreSQL database, you must set the two main PostgreSQL configuration files:

postgresql.conf
pg_hba.conf

Here is a brief description about how you can set them (note that the following description is purely indicative: To configure a machine safely, you must be familiar with all the parameters and their meanings)

First of all configure PostgreSQL service to listen on port 5432 on all network interfaces in Windows 7 machine:
open the file postgresql.conf (usually located in C:\Program Files\PostgreSQL\9.2\data) and sets the parameter

listen_addresses = '*'

Check the network address of WindowsXP virtual machine, and sets parameters in pg_hba.conf file (located in the same directory of postgresql.conf) so that postgresql can accept connections from virtual machine hosts.
For example, if the machine with Windows XP have 192.168.56.2 IP address, add in the pg_hba.conf file:

host all all 192.168.56.1/24 md5

this way, PostgreSQL will accept connections from all hosts on the network 192.168.1.XXX.

Restart the PostgreSQL service in Windows 7 (Services-> PosgreSQL 9.2: right click and restart sevice). Install pgAdmin on windows XP machine and try to connect to PostgreSQL.

Add the following code before you instantiate your web service client:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Or for backward compatibility with TLS 1.1 and prior:

System.Net.ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12; 

To initialize a 2-dimensional array use: arr = [[]*m for i in range(n)]

actually, arr = [[]*m]*n will create a 2D array in which all n arrays will point to same array, so any change in value in any element will be reflected in all n lists

for more further explanation visit : https://www.geeksforgeeks.org/python-using-2d-arrays-lists-the-right-way/

If you're dealing with Data Validation lists, you can use the Worksheet_Change event. Right click on the sheet with the data validation and choose View Code. Then type in this:

Private Sub Worksheet_Change(ByVal Target As Range)

    MsgBox Target.Value

End Sub

If you're dealing with ActiveX comboboxes, it's a little more complicated. You need to create a custom class module to hook up the events. First, create a class module named CComboEvent and put this code in it.

Public WithEvents Cbx As MSForms.ComboBox

Private Sub Cbx_Change()

    MsgBox Cbx.Value

End Sub

Next, create another class module named CComboEvents. This will hold all of our CComboEvent instances and keep them in scope. Put this code in CComboEvents.

Private mcolComboEvents As Collection

Private Sub Class_Initialize()
    Set mcolComboEvents = New Collection
End Sub

Private Sub Class_Terminate()
    Set mcolComboEvents = Nothing
End Sub

Public Sub Add(clsComboEvent As CComboEvent)

    mcolComboEvents.Add clsComboEvent, clsComboEvent.Cbx.Name

End Sub

Finally, create a standard module (not a class module). You'll need code to put all of your comboboxes into the class modules. You might put this in an Auto_Open procedure so it happens whenever the workbook is opened, but that's up to you.

You'll need a Public variable to hold an instance of CComboEvents. Making it Public will kepp it, and all of its children, in scope. You need them in scope so that the events are triggered. In the procedure, loop through all of the comboboxes, creating a new CComboEvent instance for each one, and adding that to CComboEvents.

Public gclsComboEvents As CComboEvents

Public Sub AddCombox()

    Dim oleo As OLEObject
    Dim clsComboEvent As CComboEvent

    Set gclsComboEvents = New CComboEvents

    For Each oleo In Sheet1.OLEObjects
        If TypeName(oleo.Object) = "ComboBox" Then
            Set clsComboEvent = New CComboEvent
            Set clsComboEvent.Cbx = oleo.Object
            gclsComboEvents.Add clsComboEvent
        End If
    Next oleo

End Sub

Now, whenever a combobox is changed, the event will fire and, in this example, a message box will show.

You can see an example at https://www.dropbox.com/s/sfj4kyzolfy03qe/ComboboxEvents.xlsm

you can simply use your own code but add name for the select tag

<form method="POST" action="index.php?action=contact_agent&agent_id=">
    <select name="agent_id">
        <option value="1">Agent Homer</option>
        <option value="2">Agent Lenny</option>
        <option value="3">Agent Carl</option>
    </select>

then you can access it like this

String agent=request.getparameter("agent_id");

This might be a simple solution to achieve this:

INSERT INTO funds (ID, date, price)
SELECT 23, DATE('2013-02-12'), 22.5
  FROM dual
 WHERE NOT EXISTS (SELECT 1 
                     FROM funds 
                    WHERE ID = 23
                      AND date = DATE('2013-02-12'));

p.s. alternatively (if ID a primary key):

 INSERT INTO funds (ID, date, price)
    VALUES (23, DATE('2013-02-12'), 22.5)
        ON DUPLICATE KEY UPDATE ID = 23; -- or whatever you need

see this Fiddle.

here's my refactored version which accepts multiline/single as an option

   public string ShowDialog(string text, string caption, bool isMultiline = false, int formWidth = 300, int formHeight = 200)
        {
            var prompt = new Form
            {
                Width = formWidth,
                Height = isMultiline ? formHeight : formHeight - 70,
                FormBorderStyle = isMultiline ? FormBorderStyle.Sizable : FormBorderStyle.FixedSingle,
                Text = caption,
                StartPosition = FormStartPosition.CenterScreen,
                MaximizeBox = isMultiline
            };

            var textLabel = new Label
            {
                Left = 10,
                Padding = new Padding(0, 3, 0, 0),
                Text = text,
                Dock = DockStyle.Top
            };

            var textBox = new TextBox
            {
                Left = isMultiline ? 50 : 4,
                Top = isMultiline ? 50 : textLabel.Height + 4,
                Multiline = isMultiline,
                Dock = isMultiline ? DockStyle.Fill : DockStyle.None,
                Width = prompt.Width - 24,
                Anchor = isMultiline ? AnchorStyles.Left | AnchorStyles.Top : AnchorStyles.Left | AnchorStyles.Right
            };

            var confirmationButton = new Button
            {
                Text = @"OK",
                Cursor = Cursors.Hand,
                DialogResult = DialogResult.OK,
                Dock = DockStyle.Bottom,
            };

            confirmationButton.Click += (sender, e) =>
            {
                prompt.Close();
            };

            prompt.Controls.Add(textBox);
            prompt.Controls.Add(confirmationButton);
            prompt.Controls.Add(textLabel);

            return prompt.ShowDialog() == DialogResult.OK ? textBox.Text : string.Empty;
        }

$('select[name=selValue]').val(1);
$('.selectpicker').selectpicker('refresh');

This is all you need to do. No need to change the generated html of selectpicker directly, just change the hidden select field, and then call the selectpicker('refresh').

I was looking for something that looked like jquery for generating dom in C# (I don't need to parse). Unfortunately no luck in finding a lightweight solution so I created this simple class that is inherited from System.Xml.Linq.XElement. The key feature is that you can chain the operator like when using jquery in javascript so it's more fluent. It's not fully featured but it does what I need and if there is interest I can start a git.

public class DomElement : XElement
{
    public DomElement(string name) : base(name)
    {
    }

    public DomElement(string name, string value) : base(name, value)
    {
    }

    public DomElement Css(string style, string value)
    {
        style = style.Trim();
        value = value.Trim();
        var existingStyles = new Dictionary<string, string>();
        var xstyle = this.Attribute("style");
        if (xstyle != null)
        {
            foreach (var s in xstyle.Value.Split(';'))
            {
                var keyValue = s.Split(':');
                existingStyles.Add(keyValue[0], keyValue.Length < 2 ? null : keyValue[1]);
            }
        }

        if (existingStyles.ContainsKey(style))
        {
            existingStyles[style] = value;
        }
        else
        {
            existingStyles.Add(style, value);
        }

        var styleString = string.Join(";", existingStyles.Select(s => $"{s.Key}:{s.Value}"));
        this.SetAttributeValue("style", styleString);

        return this;
    }

    public DomElement AddClass(string cssClass)
    {
        var existingClasses = new List<string>();
        var xclass = this.Attribute("class");
        if (xclass != null)
        {
            existingClasses.AddRange(xclass.Value.Split());
        }

Delete it with git tag -d <tagname> and then recreate it on the correct commit.

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

I couldn't always use pointer-events: none in my scenario, because I wanted both the overlay and the underlying element(s) to be clickable / selectable.

The DOM structure looked like this:

<div id="outerElement">
   <div id="canvas-wrapper">
      <canvas id="overlay"></canvas>
   </div>
   <!-- Omitted: element(s) behind canvas that should still be selectable -->
</div>

(The outerElement, canvas-wrapper and canvas elements have the same size.)

To make the elements behind the canvas act normally (e.g. selectable, editable), I used the following code:

canvasWrapper.style.pointerEvents = 'none';

outerElement.addEventListener('mousedown', event => {
    const clickedOnElementInCanvas = yourCheck // TODO: check if the event *would* click a canvas element.
    if (!clickedOnElementInCanvas) {

        // if necessary, add logic to deselect your canvas elements ...

        wrapper.style.pointerEvents = 'none';
        return true;
    }

    // Check if we emitted the event ourselves (avoid endless loop)
    if (event.isTrusted) {
        // Manually forward element to the canvas
        const mouseEvent = new MouseEvent(event.type, event);
        canvas.dispatchEvent(mouseEvent);
        mouseEvent.stopPropagation();
    }
    return true;
});

Some canvas objects also came with input fields, so I had to allow keyboard events, too. To do this, I had to update the pointerEvents property based on whether a canvas input field was currently focused or not:

onCanvasModified(canvas, () => {
    const inputFieldInCanvasActive = // TODO: Check if an input field of the canvas is active.
    wrapper.style.pointerEvents = inputFieldInCanvasActive  ? 'auto' : 'none';
});

The easiest is probably to create a PKCS#12 file using OpenSSL:

openssl pkcs12 -export -in abc.crt -inkey abc.key -out abc.p12

You should be able to use the resulting file directly using the PKCS12 keystore type.

If you really need to, you can convert it to JKS using keytool -importkeystore (available in keytool from Java 6):

keytool -importkeystore -srckeystore abc.p12 \
        -srcstoretype PKCS12 \
        -destkeystore abc.jks \
        -deststoretype JKS

Consider the following code:

error_reporting(E_STRICT);
class test {
    function test_arr(&$a) {
        var_dump($a);
    }
    function get_arr() {
        return array(1, 2);
    }
}

$t = new test;
$t->test_arr($t->get_arr());

This will generate the following output:

Strict Standards: Only variables should be passed by reference in `test.php` on line 14
array(2) {
  [0]=>
  int(1)
  [1]=>
  int(2)
}

The reason? The test::get_arr() method is not a variable and under strict mode this will generate a warning. This behavior is extremely non-intuitive as the get_arr() method returns an array value.

To get around this error in strict mode, either change the signature of the method so it doesn't use a reference:

function test_arr($a) {
    var_dump($a);
}

Since you can't change the signature of array_shift you can also use an intermediate variable:

$inter = get_arr();
$el = array_shift($inter);

Python

As @numeral correctly said, column._jc.toString() works fine in case of unaliased columns.

In case of aliased columns (i.e. column.alias("whatever") ) the alias can be extracted, even without the usage of regular expressions: str(column).split(" AS ")[1].split("`")[1] .

I don't know Scala syntax, but I'm sure It can be done the same.

The best way I can think of to answer this is to make a custom jquery plugin to do this:

jQuery.fn.getIdArray = function() {
  var ret = [];
  $('[id]', this).each(function() {
    ret.push(this.id);
  });
  return ret;
};

Then do something like

var array = $("#mydiv").getIdArray();

Another way is to set the version number in appDelegate didFinishLaunchingWithOptions:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
     NSString * ver = [self myVersion];
     NSLog(@"version: %@",ver);

     NSUserDefaults* userDefaults = [NSUserDefaults standardUserDefaults];
     [userDefaults setObject:ver forKey:@"version"];
     return YES;
}

- (NSString *) myVersion {
    NSString *version = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"];
    NSString *build = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleVersion"];
    return [NSString stringWithFormat:@"%@ build %@", version, build];
}

If you by any chance using java for configuration, you may need to check the below bean declaration if you have package level changes. Eg: com.abc.spring package changed to com.bbc.spring

@Bean
    public SessionFactory sessionFactory() {

        LocalSessionFactoryBuilder builder = new LocalSessionFactoryBuilder(dataSource());
        //builder.scanPackages("com.abc.spring");    //Comment this line as this package no longer valid.
        builder.scanPackages("com.bbc.spring");
        builder.addProperties(getHibernationProperties());

        return builder.buildSessionFactory();
    }

add apache.commons dependency on your pom.xml

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-io</artifactId>
    <version>1.3.2</version>
</dependency>

And below code works.

StringUtils.substringBetween(String mydata, String "'", String "'")

You can do it converting by the constructor to a string using .toString() :

function getObjectClass(obj){
   if (typeof obj != "object" || obj === null) return false;
   else return /(\w+)\(/.exec(obj.constructor.toString())[1];}

Try:

Select * Into <DestinationTableName> From <SourceTableName> Where 1 = 2

Note that this will not copy indexes, keys, etc.

If you want to copy the entire structure, you need to generate a Create Script of the table. You can use that script to create a new table with the same structure. You can then also dump the data into the new table if you need to.

If you are using Enterprise Manager, just right-click the table and select copy to generate a Create Script.

This is what I recently used, and it worked fine for me:

NSString *post = @"key1=val1&key2=val2";
NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:@"http://www.nowhere.com/sendFormHere.php"]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

yourLabel.intrinsicContentSize.width for Objective-C / Swift

I've always found it easier to invert the test against the list in situations like this. For instance...

SELECT 
    field0, field1, field2 
FROM 
    my_table 
WHERE 
    ',' + @mysearchlist + ',' LIKE '%,' + CAST(field3 AS VARCHAR) + ',%' 

This means that there is no complicated mish-mash required for the values that you are looking for.

As an example, if our list was ('1,2,3'), then we add a comma to the start and end of our list like so: ',' + @mysearchlist + ','.

We also do the same for the field value we're looking for and add wildcards: '%,' + CAST(field3 AS VARCHAR) + ',%' (notice the % and the , characters).

Finally we test the two using the LIKE operator: ',' + @mysearchlist + ',' LIKE '%,' + CAST(field3 AS VARCHAR) + ',%'.

As an alternative to rewriting history, consider using git replace as in this article from the Pro Git book. The example discussed involves replacing a parent commit to simulate the beginning of a tree, while still keeping the full history as a separate branch for safekeeping.

Small script that print, centered in bottom of the page, the script execution that started at server call with microsecond precision.

So as not to distort the result and to be 100% compatible with content in page, I used, to write the result on the page, a browser-side native javascript snippet.

//Uncomment the line below to test with 2 seconds 
//usleep(2000000);

$prec = 5; // numbers after comma
$time = number_format(microtime(true) - $_SERVER['REQUEST_TIME_FLOAT'], $prec, '.', '');
echo "<script>
    if(!tI) { 
        var tI=document.createElement('div');
        tI.style.fontSize='8px';
        tI.style.marginBottom='5px';
        tI.style.position='absolute';
        tI.style.bottom='0px';
        tI.style.textAlign='center';
        tI.style.width='98%';
        document.body.appendChild(tI);
    }
    tI.innerHTML='$time';
</script>";

Another approach is to make the snippet as small as possible, and style it with a class in your stylesheet.

1. Replace the echo ...; part with the following:

   echo "<script>if(!tI){var tI=document.createElement('div');tI.className='ldtme';document.body.appendChild(tI);}tI.innerHTML='$time';</script>";

2. In your CSS create and fill the .ldtme{...} class.

If you wan to provide lollipop support notification icon then make two type notification icon :

1. normal notification icon : for below lollipop version.
2. notification icon with transparent background : for lollipop and above version.

Now set appropriate icon to notification builder at run time base on OS version :

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    mBuilder.setSmallIcon(R.drawable.ic_push_notification_transperent);
} else {
    mBuilder.setSmallIcon(R.drawable.ic_push_notification);
}

Probably the SIMPLEST method is this:

super.setBackground(Color.CYAN);

You must extend JFrame in the class before doing this!

The PrimeFaces ajax events sometimes are very poorly documented, so in most cases you must go to the source code and check yourself.

p:selectOneMenu supports change event:

<p:selectOneMenu ..>
    <p:ajax event="change" update="msgtext"
        listener="#{post.subjectSelectionChanged}" />
    <!--...-->
</p:selectOneMenu>

which triggers listener with AjaxBehaviorEvent as argument in signature:

public void subjectSelectionChanged(final AjaxBehaviorEvent event)  {...}

Delegate are essentially inline Action's or Func<T>. You can declare a delegate outside the scope of a method which you are running or using a lambda expression(=>); because you run the delegate within a method, you run it on the thread which is being run for the current window/application which is the bit in bold.

Lambda example

int AddFiveToNumber(int number)
{
  var d = (int i => i + 5);
  d.Invoke(number);
}

I justed faced very similar problem... BUT RegExp_Count couldn't resolved it. How many times string '16,124,3,3,1,0,' contains ',3,'? As we see 2 times, but RegExp_Count returns just 1. Same thing is with ''bbaaaacc' and when looking in it 'aa' - should be 3 times and RegExp_Count returns just 2.

select REGEXP_COUNT('336,14,3,3,11,0,' , ',3,') from dual;
select REGEXP_COUNT('bbaaaacc' , 'aa') from dual;

I lost some time to research solution on web. Couldn't' find... so i wrote my own function that returns TRUE number of occurance. Hope it will be usefull.

CREATE OR REPLACE FUNCTION EXPRESSION_COUNT( pEXPRESSION VARCHAR2, pPHRASE VARCHAR2 ) RETURN NUMBER AS
  vRET NUMBER := 0;
  vPHRASE_LENGTH NUMBER := 0;
  vCOUNTER NUMBER := 0;
  vEXPRESSION VARCHAR2(4000);
  vTEMP VARCHAR2(4000);
BEGIN
  vEXPRESSION := pEXPRESSION;
  vPHRASE_LENGTH := LENGTH( pPHRASE );
  LOOP
    vCOUNTER := vCOUNTER + 1;
    vTEMP := SUBSTR( vEXPRESSION, 1, vPHRASE_LENGTH);
    IF (vTEMP = pPHRASE) THEN        
        vRET := vRET + 1;
    END IF;
    vEXPRESSION := SUBSTR( vEXPRESSION, 2, LENGTH( vEXPRESSION ) - 1);
  EXIT WHEN ( LENGTH( vEXPRESSION ) = 0 ) OR (vEXPRESSION IS NULL);
  END LOOP;
  RETURN vRET;
END;

export in sh and related shells (such as bash), marks an environment variable to be exported to child-processes, so that the child inherits them.

export is defined in POSIX:

The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the environment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to word.

You also run into this issue when you are creating routine in a class module.

When you try to run the code externally, you get this error.
You can't assign macro to button to a member of a class module either.

If you try to run from within the code by pressing green play button you will also see the same error.

Either move the routine in to a regular module or create a new routine in a regular module that calls the class member.

Update: ES6 version:

const dates = dates_as_int.map(date => new Date(date).getTime())

When you write a "string" in your source code, it gets written directly into the executable because that value needs to be known at compile time (there are tools available to pull software apart and find all the plain text strings in them). When you write char *a = "This is a string", the location of "This is a string" is in the executable, and the location a points to, is in the executable. The data in the executable image is read-only.

What you need to do (as the other answers have pointed out) is create that memory in a location that is not read only--on the heap, or in the stack frame. If you declare a local array, then space is made on the stack for each element of that array, and the string literal (which is stored in the executable) is copied to that space in the stack.

char a[] = "This is a string";

you can also copy that data manually by allocating some memory on the heap, and then using strcpy() to copy a string literal into that space.

char *a = malloc(256);
strcpy(a, "This is a string");

Whenever you allocate space using malloc() remember to call free() when you are finished with it (read: memory leak).

Basically, you have to keep track of where your data is. Whenever you write a string in your source, that string is read only (otherwise you would be potentially changing the behavior of the executable--imagine if you wrote char *a = "hello"; and then changed a[0] to 'c'. Then somewhere else wrote printf("hello");. If you were allowed to change the first character of "hello", and your compiler only stored it once (it should), then printf("hello"); would output cello!)

Maybe you want unpack elements of array, I don't know if I got it, but below a example:

def my_func(*args):
    for a in args:
        print a

my_func(*[1,2,3,4])
my_list = ['a','b','c']
my_func(*my_list)

Actually, none of the given answers are fully cover the request.
As the OP didn't provided a specific use case or types of numbers, I will try to cover all possible cases and permutations.

Regular Numbers

Whole Positive

This number is usually called unsigned integer, but you can also call it a positive non-fractional number, include zero. This includes numbers like 0, 1 and 99999.
The Regular Expression that covers this validation is:

/^(0|[1-9]\d*)$/

Test This Regex

Whole Positive and Negative

This number is usually called signed integer, but you can also call it a non-fractional number. This includes numbers like 0, 1, 99999, -99999, -1 and -0.
The Regular Expression that covers this validation is:

/^-?(0|[1-9]\d*)$/

Test This Regex

As you probably noticed, I have also included -0 as a valid number. But, some may argue with this usage, and tell that this is not a real number (you can read more about Signed Zero here). So, if you want to exclude this number from this regex, here's what you should use instead:

/^-?(0|[1-9]\d*)(?<!-0)$/

Test This Regex

All I have added is (?<!-0), which means not to include -0 before this assertion. This (?<!...) assertion called negative lookbehind, which means that any phrase replaces the ... should not appear before this assertion. Lookbehind has limitations, like the phrase cannot include quantifiers. That's why for some cases I'll be using Lookahead instead, which is the same, but in the opposite way.

Many regex flavors, including those used by Perl and Python, only allow fixed-length strings. You can use literal text, character escapes, Unicode escapes other than \X, and character classes. You cannot use quantifiers or backreferences. You can use alternation, but only if all alternatives have the same length. These flavors evaluate lookbehind by first stepping back through the subject string for as many characters as the lookbehind needs, and then attempting the regex inside the lookbehind from left to right.

You can read more bout Lookaround assertions here.

Fractional Numbers

Positive

This number is usually called unsigned float or unsigned double, but you can also call it a positive fractional number, include zero. This includes numbers like 0, 1, 0.0, 0.1, 1.0, 99999.000001, 5.10.
The Regular Expression that covers this validation is:

/^(0|[1-9]\d*)(\.\d+)?$/

Test This Regex

Some may say, that numbers like .1, .0 and .00651 (same as 0.1, 0.0 and 0.00651 respectively) are also valid fractional numbers, and I cannot disagree with them. So here is a regex that is additionally supports this format:

/^(0|[1-9]\d*)?(\.\d+)?(?<=\d)$/

Test This Regex

Negative and Positive

This number is usually called signed float or signed double, but you can also call it a fractional number. This includes numbers like 0, 1, 0.0, 0.1, 1.0, 99999.000001, 5.10, -0, -1, -0.0, -0.1, -99999.000001, 5.10.
The Regular Expression that covers this validation is:

/^-?(0|[1-9]\d*)(\.\d+)?$/

Test This Regex

For non -0 believers:

/^(?!-0(\.0+)?$)-?(0|[1-9]\d*)(\.\d+)?$/

Test This Regex

For those who want to support also the invisible zero representations, like .1, -.1, use the following regex:

/^-?(0|[1-9]\d*)?(\.\d+)?(?<=\d)$/

Test This Regex

The combination of non -0 believers and invisible zero believers, use this regex:

/^(?!-0?(\.0+)?$)-?(0|[1-9]\d*)?(\.\d+)?(?<=\d)$/

Test This Regex

Numbers with a Scientific Notation (AKA Exponential Notation)

Some may want to support in their validations, numbers with a scientific character e, which is by the way, an absolutely valid number, it is created for shortly represent a very long numbers. You can read more about Scientific Notation here. These numbers are usually looks like 1e3 (which is 1000), 1e-3 (which is 0.001) and are fully supported by many major programming languages (e.g. JavaScript). You can test it by checking if the expression '1e3'==1000 returns true.
I will divide the support for all the above sections, including numbers with scientific notation.

Regular Numbers

Whole positive number regex validation, supports numbers like 6e4, 16e-10, 0e0 but also regular numbers like 0, 11:

/^(0|[1-9]\d*)(e-?(0|[1-9]\d*))?$/i

Test This Regex

Whole positive and negative number regex validation, supports numbers like -6e4, -16e-10, -0e0 but also regular numbers like -0, -11 and all the whole positive numbers above:

/^-?(0|[1-9]\d*)(e-?(0|[1-9]\d*))?$/i

Test This Regex

Whole positive and negative number regex validation for non -0 believers, same as the above, except now it forbids numbers like -0, -0e0, -0e5 and -0e-6:

/^(?!-0)-?(0|[1-9]\d*)(e-?(0|[1-9]\d*))?$/i

Test This Regex

Fractional Numbers

Positive number regex validation, supports also the whole numbers above, plus numbers like 0.1e3, 56.0e-3, 0.0e10 and 1.010e0:

/^(0|[1-9]\d*)(\.\d+)?(e-?(0|[1-9]\d*))?$/i

Test This Regex

Positive number with invisible zero support regex validation, supports also the above positive numbers, in addition numbers like .1e3, .0e0, .0e-5 and .1e-7:

/^(0|[1-9]\d*)?(\.\d+)?(?<=\d)(e-?(0|[1-9]\d*))?$/i

Test This Regex

Negative and positive number regex validation, supports the positive numbers above, but also numbers like -0e3, -0.1e0, -56.0e-3 and -0.0e10:

/^-?(0|[1-9]\d*)(\.\d+)?(e-?(0|[1-9]\d*))?$/i

Test This Regex

Negative and positive number regex validation fro non -0 believers, same as the above, except now it forbids numbers like -0, -0.00000, -0.0e0, -0.00000e5 and -0e-6:

/^(?!-0(\.0+)?(e|$))-?(0|[1-9]\d*)(\.\d+)?(e-?(0|[1-9]\d*))?$/i

Negative and positive number with invisible zero support regex validation, supports also the above positive and negative numbers, in addition numbers like -.1e3, -.0e0, -.0e-5 and -.1e-7:

/^-?(0|[1-9]\d*)?(\.\d+)?(?<=\d)(e-?(0|[1-9]\d*))?$/i

Test This Regex

Negative and positive number with the combination of non -0 believers and invisible zero believers, same as the above, but forbids numbers like -.0e0, -.0000e15 and -.0e-19:

/^(?!-0?(\.0+)?(e|$))-?(0|[1-9]\d*)?(\.\d+)?(?<=\d)(e-?(0|[1-9]\d*))?$/i

Numbers with Hexadecimal Representation

In many programming languages, string representation of hexadecimal number like 0x4F7A may be easily cast to decimal number 20346.
Thus, one may want to support it in his validation script.
The following Regular Expression supports only hexadecimal numbers representations:

/^0x[0-9a-f]+$/i

Test This Regex

All Permutations

These final Regular Expressions, support the invisible zero numbers.

Signed Zero Believers

/^(-?(0|[1-9]\d*)?(\.\d+)?(?<=\d)(e-?(0|[1-9]\d*))?|0x[0-9a-f]+)$/i

Hope I covered all number permutations that are supported in many programming languages.
Good luck!

Oh, forgot to mention, that those who want to validate a number includes a thousand separator, you should clean all the commas (,) first, as there may be any type of separator out there, you can't actually cover them all.
But you can remove them first, before the number validation:

//JavaScript
function clearSeparators(number)
{
    return number.replace(/,/g,'');
}

JAXB Limitation.

I worked on JAXB, as per my opinion its a nice way of dealing with data between XML and Java objects. The Positive sides are its proven and better in performance and control over the data during runtime. With a good usage of built tools or scripts it will takes away lot of coding efforts.

I found the configuration part is not a straight away task, and spent hours in getting the development environment setup.

However I dropped this solution due to a silly limitation I faced. My XML Schema Definition ( XSD ) has a attribute/element with name "value" and that I have to use XSD as it is. This very little constraint forced the my binding step XJC failed with a Error "Property 'Value' already used."

This is due to the JAXB implementation, the binding process tries to create Java objects out of XSD by adding few attributes to each class and one of them being a value attribute. When it processed my XSD it complained that there is already a property with that name.

How about

with open(csv_input_path + file, 'r') as ft:
    header = ft.readline() # read only first line; returns string
    header_list = header.split(',') # returns list

I am assuming your input file is CSV format. If using pandas, it takes more time if the file is big size because it loads the entire data as the dataset.

On my machine:

C:\Program Files\PostgreSQL\8.4\data\postgresql.conf

$("#pageCSS").attr('href', './css/new_css.css');

I think that concat method and + should be mentioned here as well:

assert_eq!(
  ("My".to_owned() + " " + "string"),
  ["My", " ", "string"].concat()
);

and there is also concat! macro but only for literals:

let s = concat!("test", 10, 'b', true);
assert_eq!(s, "test10btrue");

Another way to fix this would be to go to the properties of the server on eclipse (right click on server -> properties) In general tab you would see location as workspace.metadata. Click on switch location.

If your code seems too unwieldy, a function might help:

def clamp(minvalue, value, maxvalue):
    return max(minvalue, min(value, maxvalue))

new_index = clamp(0, new_index, len(mylist)-1)

you can use line.seperator for appending new line in

The answer was surprisingly simple. I had to add a Content-Type header in the POST request with a value of application/json. Without this header Jersey did not know what to do with the request body (in spite of the @Consumes(MediaType.APPLICATION_JSON) annotation)!

You can notify your users that there is a new version of the current app available to update. Also, if this condition is true, you can block login in the app.

Please see if this provides you the solution.

This works for me to find queries on any database in the instance. I'm sysadmin on the instance (check your privileges):

SELECT deqs.last_execution_time AS [Time], dest.text AS [Query], dest.*
FROM sys.dm_exec_query_stats AS deqs
CROSS APPLY sys.dm_exec_sql_text(deqs.sql_handle) AS dest
WHERE dest.dbid = DB_ID('msdb')
ORDER BY deqs.last_execution_time DESC

This is the same answer that Aaron Bertrand provided but it wasn't placed in an answer.

In order to do this without FuncAnimation (eg you want to execute other parts of the code while the plot is being produced or you want to be updating several plots at the same time), calling draw alone does not produce the plot (at least with the qt backend).

The following works for me:

import matplotlib.pyplot as plt
plt.ion()
class DynamicUpdate():
    #Suppose we know the x range
    min_x = 0
    max_x = 10

    def on_launch(self):
        #Set up plot
        self.figure, self.ax = plt.subplots()
        self.lines, = self.ax.plot([],[], 'o')
        #Autoscale on unknown axis and known lims on the other
        self.ax.set_autoscaley_on(True)
        self.ax.set_xlim(self.min_x, self.max_x)
        #Other stuff
        self.ax.grid()
        ...

    def on_running(self, xdata, ydata):
        #Update data (with the new _and_ the old points)
        self.lines.set_xdata(xdata)
        self.lines.set_ydata(ydata)
        #Need both of these in order to rescale
        self.ax.relim()
        self.ax.autoscale_view()
        #We need to draw *and* flush
        self.figure.canvas.draw()
        self.figure.canvas.flush_events()

    #Example
    def __call__(self):
        import numpy as np
        import time
        self.on_launch()
        xdata = []
        ydata = []
        for x in np.arange(0,10,0.5):
            xdata.append(x)
            ydata.append(np.exp(-x**2)+10*np.exp(-(x-7)**2))
            self.on_running(xdata, ydata)
            time.sleep(1)
        return xdata, ydata

d = DynamicUpdate()

You can increase the List View Threshold beyond the 5,000 default, but it is highly recommended that you don't, as it has performance implications. The recommended fix is to add an index to the field or fields used in the query (usually the ID field for a list or the Title field for a library).

When there is an index, that is used to retrieve the item(s); when there is no index the whole list is opened for a scan (and therefore hits the threshold). You create the index on the List (or Library) settings page.

This article is a good overview: http://office.microsoft.com/en-us/sharepoint-foundation-help/manage-lists-and-libraries-with-many-items-HA010377496.aspx

In my case, I got this no cipher suites in common error because I've loaded a p12 format file to the keystore of the server, instead of a jks file.

Sound like you just have an issue with the path. Include the full path, if you use backslashes they need to be escaped: "C:\\folder\\folder\\Desktop\\file.csv" or "C:/folder/folder/Desktop/file.csv".

myfile = read.csv("C:/folder/folder/Desktop/file.csv")  # or read.table()

It may also be wise to avoid spaces and symbols in your file names, though I'm fairly certain spaces are OK.

Please notice that the article that dowski and Panos was reffering to (MSDN Win32_Printer) can be a little misleading.

I'm referring the first value of most of the arrays. some begins with 1 and some begins with 0. for example, "ExtendedPrinterStatus" first value in table is 1, therefore, your array should be something like this:

string[] arrExtendedPrinterStatus = { 
    "","Other", "Unknown", "Idle", "Printing", "Warming Up",
    "Stopped Printing", "Offline", "Paused", "Error", "Busy",
    "Not Available", "Waiting", "Processing", "Initialization",
    "Power Save", "Pending Deletion", "I/O Active", "Manual Feed"
};

and on the other hand, "ErrorState" first value in table is 0, therefore, your array should be something like this:

string[] arrErrorState = {
    "Unknown", "Other", "No Error", "Low Paper", "No Paper", "Low Toner",
    "No Toner", "Door Open", "Jammed", "Offline", "Service Requested",
    "Output Bin Full"
};

BTW, "PrinterState" is obsolete, but you can use "PrinterStatus".

Fusion charts has a new javascript/jquery library that looks promising.

It's an older question, but if anyone has a problem with setting this, their documentation is outdated. I made a copy of the php.ini file named php5.ini and now it works.

In one of my projects there was a nuget packages with higher version of System.Net.Http. and in my startup project there reference to System.Net.Http v 4.0.0 , i just installed System.Net.Http nuget package in my startup project and the problem solved

import android.graphics.Matrix
public Bitmap getResizedBitmap(Bitmap bm, int newWidth, int newHeight) {
    int width = bm.getWidth();
    int height = bm.getHeight();
    float scaleWidth = ((float) newWidth) / width;
    float scaleHeight = ((float) newHeight) / height;
    // CREATE A MATRIX FOR THE MANIPULATION
    Matrix matrix = new Matrix();
    // RESIZE THE BIT MAP
    matrix.postScale(scaleWidth, scaleHeight);

    // "RECREATE" THE NEW BITMAP
    Bitmap resizedBitmap = Bitmap.createBitmap(
        bm, 0, 0, width, height, matrix, false);
    bm.recycle();
    return resizedBitmap;
}

EDIT: as suggested by by @aveschini, I have added bm.recycle(); for memory leaks. Please note that in case if you are using the previous object for some other purposes, then handle accordingly.

To convert you PHP array to JS , you can do it like this :

var js_array = [<?php echo '"'.implode('","',  $disabledDaysRange ).'"' ?>];

or using JSON_ENCODE :

var js_array =<?php echo json_encode($disabledDaysRange );?>;

Example without JSON_ENCODE:

<script type='text/javascript'>
    <?php
    $php_array = array('abc','def','ghi');
    ?>
    var js_array = [<?php echo '"'.implode('","', $php_array).'"' ?>];
    alert(js_array[0]);
</script>

Example with JSON_ENCODE :

<script type='text/javascript'>
    <?php
    $php_array = array('abc','def','ghi');
    ?>
    var js_array =<?php echo json_encode($disabledDaysRange );?>;
    alert(js_array[0]);
</script>

In a Helper file,

Your can use Route::current()->uri() to get current URL.

Hence, If you compare your route name to set active class on menu then it would be good if you use

Route::currentRouteName() to get the name of route and compare

Use a negative lookahead and a negative lookbehind:

> s = "one two 3.4 5,6 seven.eight nine,ten"
> parts = re.split('\s|(?<!\d)[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten']

In other words, you always split by \s (whitespace), and only split by commas and periods if they are not followed (?!\d) or preceded (?<!\d) by a digit.

DEMO.

EDIT: As per @verdesmarald comment, you may want to use the following instead:

> s = "one two 3.4 5,6 seven.eight nine,ten,1.2,a,5"
> print re.split('\s|(?<!\d)[,.]|[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten', '1.2', 'a', '5']

This will split "1.2,a,5" into ["1.2", "a", "5"].

DEMO.

Just for future reference, this problem happened with me, using Vagrant 1.7.4 and VirtualBox 5.0.10 r104061, when I provisioned a shared folder in / and created a symbolic link to my home folder. Something like this:

/folder
~/folder -> /folder

Apparently, this operation is not allowed by Vagrant due to security purposes and throws the described error.

I solved it by provisioning the desired folder directly to my home directory, such as /home/vagrant/folder.

I believe fcntl() is a POSIX function. Where as ioctl() is a standard UNIX thing. Here is a list of POSIX io. ioctl() is a very kernel/driver/OS specific thing, but i am sure what you use works on most flavors of Unix. some other ioctl() stuff might only work on certain OS or even certain revs of it's kernel.

I just put this together from what morty346 posted:

set folder="C:\test"
IF EXIST "%folder%" (
    cd /d %folder%
    for /F "delims=" %%i in ('dir /b') do (rmdir "%%i" /s/q || del "%%i" /s/q)
)

It adds a quick check that the folder defined in the variable exists first, changes directory to the folder, and deletes the contents.

Use the in operator: e.g. "key1" in a.

Instead of

background-repeat-x: no-repeat;
background-repeat-y: no-repeat;

which is not correct, use

background-repeat: no-repeat;

n % x == 0

Means that n can be divided by x. So... for instance, in your case:

boolean isDivisibleBy20 = number % 20 == 0;

Also, if you want to check whether a number is even or odd (whether it is divisible by 2 or not), you can use a bitwise operator:

boolean even = (number & 1) == 0;
boolean odd  = (number & 1) != 0;

When the accepted answer doesn't work (for example when dealing with Paint) you can use:

float spTextSize = 12;
float textSize = spTextSize * getResources().getDisplayMetrics().scaledDensity;
textPaint.setTextSize(textSize);

Just point to the dictionary at given key and assign a new value:

myDictionary[myKey] = myNewValue;

Linq equivalents of Map and Reduce: If you’re lucky enough to have linq then you don’t need to write your own map and reduce functions. C# 3.5 and Linq already has it albeit under different names.

• Map is Select:

  Enumerable.Range(1, 10).Select(x => x + 2);
  

• Reduce is Aggregate:

  Enumerable.Range(1, 10).Aggregate(0, (acc, x) => acc + x);
  

• Filter is Where:

  Enumerable.Range(1, 10).Where(x => x % 2 == 0);

The only way is to obfuscate javascript or minify your javascript which makes it hard for the end user to reverse engineer. however its not impossible to reverse engineer.

    List<int> first_list = new List<int>() {
        1,
        12,
        12,
        5
    };

    List<int> second_list = new List<int>() {
        12,
        5,
        7,
        9,
        1
    };

    var result = first_list.Union(second_list);

If you need two or more dealings with the filter, is possible to chain them:

{{ value | decimalRound: 2 | currencySimbol: 'U$' }} 
// 11.1111 becomes U$ 11.11

If you're using SQL Server 2005 or later (and the tags for your question indicate SQL Server 2008), you can use ranking functions to return the duplicate records after the first one if using joins is less desirable or impractical for some reason. The following example shows this in action, where it also works with null values in the columns examined.

create table Table1 (
 Field1 int,
 Field2 int,
 Field3 int,
 Field4 int 
)

insert  Table1 
values    (1,1,1,1)
        , (1,1,1,2)
        , (1,1,1,3)
        , (2,2,2,1)
        , (3,3,3,1)
        , (3,3,3,2)
        , (null, null, 2, 1)
        , (null, null, 2, 3)

select    *
from     (select      Field1
                    , Field2
                    , Field3
                    , Field4
                    , row_number() over (partition by   Field1
                                                      , Field2
                                                      , Field3
                                         order by       Field4) as occurrence
          from      Table1) x
where     occurrence > 1

Notice after running this example that the first record out of every "group" is excluded, and that records with null values are handled properly.

If you don't have a column available to order the records within a group, you can use the partition-by columns as the order-by columns.

You can use also

select * from tablename where column1 ='a' and column2!='b';

You can try using get_the_category():

$categories = get_the_category();
$category_id = $categories[0]->cat_ID;

You need enctype="multipart/form-data" otherwise you will load only the file name and not the data.

Please do not reinvent the wheel. There are many open-source & COTS solutions that already exist to solve this problem.

Please take a look at the following JavaScript libraries:

• Moment.js: [Source] | [Minified]

• Datejs: [Source] | [Alpha1.zip (1.6MB)]

Demo

I wrote a one-liner using Moment.js below. You can check out the demo here: JSFiddle.

moment('2014-08-20 15:30:00').format('MM/DD/YYYY h:mm a'); // 08/20/2014 3:30 pm

You can try using blockinfile instead.

You can do something like

- blockinfile: |
    dest=/etc/network/interfaces backup=yes
    content="iface eth0 inet static
        address 192.168.0.1
        netmask 255.255.255.0"

You need to use the CONCAT() function in MySQL for string concatenation:

UPDATE categories SET code = CONCAT(code, '_standard') WHERE id = 1;

I know this is an old one with an accepted answer, and that answer works great.. IF you are not styling the background and floating the final inputs left. If you are, then the form background will not include the floated input fields.

To avoid this make the divs with the smaller input fields inline-block rather than float left.

This:

<div style="display:inline-block;margin-right:20px;">
    <label for="name">Name</label>
    <input id="name" type="text" value="" name="name">
</div>

Rather than:

<div style="float:left;margin-right:20px;">
    <label for="name">Name</label>
    <input id="name" type="text" value="" name="name">
</div>

I search into this question becuase: I create a new directory and it contains many files. Among these files, some I want to add to git repository and some not. But when I do "git status". It only shows:

Untracked files:
  (use "git add <file>..." to include in what will be committed)
    ../trine/device_android/

It does not list the seperate files in this new directory. Then I think maybe I can add this directory only and then deal with the seperate files. So I google "git add directory only".

In my situation, I found I can just add one file in the new directory that I am sure I want to add it to git.

git add new_folder/some_file

After this, "git status" will show the status of seperate files.

a possible solution in js

In case the WebSocket server initiative disconnects the ws link after a few minutes there no messages sent between the server and client.

1. client sends a custom ping message, to keep alive by using the keepAlive function

2. server ignore the ping message and response a custom pong message

var timerID = 0; 
function keepAlive() { 
    var timeout = 20000;  
    if (webSocket.readyState == webSocket.OPEN) {  
        webSocket.send('');  
    }  
    timerId = setTimeout(keepAlive, timeout);  
}  
function cancelKeepAlive() {  
    if (timerId) {  
        clearTimeout(timerId);  
    }  
}

I've just found a great tool for that need, it is called tabulate.

It prints tabular data and works with DataFrame.

from tabulate import tabulate
import pandas as pd

df = pd.DataFrame({'col_two' : [0.0001, 1e-005 , 1e-006, 1e-007],
                   'column_3' : ['ABCD', 'ABCD', 'long string', 'ABCD']})
print(tabulate(df, headers='keys', tablefmt='psql'))

+----+-----------+-------------+
|    |   col_two | column_3    |
|----+-----------+-------------|
|  0 |    0.0001 | ABCD        |
|  1 |    1e-05  | ABCD        |
|  2 |    1e-06  | long string |
|  3 |    1e-07  | ABCD        |
+----+-----------+-------------+

Edit:
r means row and w waiting time.
When you initially press start button 80 (or any other number) of concurrent ajax request are launched by javascript, but as is known they are spooled by the browser. Also they are requested to the server in parallel (limited to certain number, this is the fact of this question). Here the requests are solved server side with a random delay (established by w). At start time all the time needed to solve all ajax calls is calculated. When test is finished, you can see if it took half, took third, took a quarter, etc of the total time, deducting which was the parallelism on the calls to the server. This is not strict, nor precise, but is nice to see in real time how ajaxs calls are completed (seeing the incoming cross). And is a very simple self contained script to show ajax basics.
Of course, this assumes, that server side is not introducing any extra limit.
Preferably use in conjunction with firebug net panel (or your browser's equivalent)

I got a similar error with '/' operand while processing images. I discovered the folder included a text file created by the 'XnView' image viewer. So, this kind of error occurs when some object is not the kind of object expected.

I know this is kinda an old question but:

root["bg"] = "black"

will also do what you want and it involves less typing.

Since you have a FULL backup, you can restore the backup to a different server as a database of the same name or to the same server with a different name.

Then you can just review the contents pre-update and write a SQL script to do the update.

Try this:

$('select option:selected').text();

I also experienced an issue like this, my workspace was corrupted and didn't do all the important things anymore.

For some reason, I had a corrupt resource on one of my projects. It didn't show up in the package tree, but it did show in the error log in Eclipse as

Error while creating a link for external folder X:\somefolder

After checking every project (because the error didn't point to one), I indeed found this resource in one of the build paths (in Configure Build Path menu it did show an error icon!) and deleted it.

See Eclipse (Kepler) Workspace acting weird (type hierarchy, searching for references not working) for a wider description of my issue if you're experiencing something similar.

Posted this for future developers to reference.

Imagine you are developing a web-application and you decide to decouple the functionality from the presentation of the application, because it affords greater freedom.

You create an API and let others implement their own front-ends over it as well. What you just did here is implement an SOA methodology, i.e. using web-services.

Web services make functional building-blocks accessible over standard Internet protocols independent of platforms and programming languages.

So, you design an interchange mechanism between the back-end (web-service) that does the processing and generation of something useful, and the front-end (which consumes the data), which could be anything. (A web, mobile, or desktop application, or another web-service). The only limitation here is that the front-end and back-end must "speak" the same "language".

That's where SOAP and REST come in. They are standard ways you'd pick communicate with the web-service.

SOAP:

SOAP internally uses XML to send data back and forth. SOAP messages have rigid structure and the response XML then needs to be parsed. WSDL is a specification of what requests can be made, with which parameters, and what they will return. It is a complete specification of your API.

REST:

REST is a design concept.

The World Wide Web represents the largest implementation of a system conforming to the REST architectural style.

It isn't as rigid as SOAP. RESTful web-services use standard URIs and methods to make calls to the webservice. When you request a URI, it returns the representation of an object, that you can then perform operations upon (e.g. GET, PUT, POST, DELETE). You are not limited to picking XML to represent data, you could pick anything really (JSON included)

Flickr's REST API goes further and lets you return images as well.

JSON and XML, are functionally equivalent, and common choices. There are also RPC-based frameworks like GRPC based on Protobufs, and Apache Thrift that can be used for communication between the API producers and consumers. The most common format used by web APIs is JSON because of it is easy to use and parse in every language.

a = getUniques(a)
arrInfo a
End Sub

Function getUniques(a, Optional ZeroBased As Boolean = True)
Dim tmp: tmp = Application.Transpose(WorksheetFunction.Unique(a))
If ZeroBased Then ReDim Preserve tmp(0 To UBound(tmp) - 1)
getUniques = tmp
End Function

This is a server side issue. You don't need to add any headers in angular for cors. You need to add header on the server side:

Access-Control-Allow-Headers: Content-Type
Access-Control-Allow-Methods: GET, POST, OPTIONS
Access-Control-Allow-Origin: *

If you want a string mm/dd/yyyy instead of the datetime object, you can use strftime (string format time):

>>> dt.datetime.today().strftime("%m/%d/%Y")
                   # ^ note parentheses
'02/12/2014'

firstobject's 605k download lightweight native Windows free XML editor opens a 50MB file in 1.3 seconds and provides text editing, search, syntax-colored printing, plus tree view and additional XML features including formatting and full-blown CMarkup scripting built in.

This answer is based on this excellent answer by 18446744073709551615. Their solution, though helpful, does not size the image icon with the surrounding text. It also doesn't set the icon colour to that of the surrounding text.

The solution below takes a white, square icon and makes it fit the size and colour of the surrounding text.

public class TextViewWithImages extends TextView {

    private static final String DRAWABLE = "drawable";
    /**
     * Regex pattern that looks for embedded images of the format: [img src=imageName/]
     */
    public static final String PATTERN = "\\Q[img src=\\E([a-zA-Z0-9_]+?)\\Q/]\\E";

    public TextViewWithImages(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    public TextViewWithImages(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public TextViewWithImages(Context context) {
        super(context);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        final Spannable spannable = getTextWithImages(getContext(), text, getLineHeight(), getCurrentTextColor());
        super.setText(spannable, BufferType.SPANNABLE);
    }

    private static Spannable getTextWithImages(Context context, CharSequence text, int lineHeight, int colour) {
        final Spannable spannable = Spannable.Factory.getInstance().newSpannable(text);
        addImages(context, spannable, lineHeight, colour);
        return spannable;
    }

    private static boolean addImages(Context context, Spannable spannable, int lineHeight, int colour) {
        final Pattern refImg = Pattern.compile(PATTERN);
        boolean hasChanges = false;

        final Matcher matcher = refImg.matcher(spannable);
        while (matcher.find()) {
            boolean set = true;
            for (ImageSpan span : spannable.getSpans(matcher.start(), matcher.end(), ImageSpan.class)) {
                if (spannable.getSpanStart(span) >= matcher.start()
                        && spannable.getSpanEnd(span) <= matcher.end()) {
                    spannable.removeSpan(span);
                } else {
                    set = false;
                    break;
                }
            }
            final String resName = spannable.subSequence(matcher.start(1), matcher.end(1)).toString().trim();
            final int id = context.getResources().getIdentifier(resName, DRAWABLE, context.getPackageName());
            if (set) {
                hasChanges = true;
                spannable.setSpan(makeImageSpan(context, id, lineHeight, colour),
                        matcher.start(),
                        matcher.end(),
                        Spannable.SPAN_EXCLUSIVE_EXCLUSIVE
                );
            }
        }
        return hasChanges;
    }

    /**
     * Create an ImageSpan for the given icon drawable. This also sets the image size and colour.
     * Works best with a white, square icon because of the colouring and resizing.
     *
     * @param context       The Android Context.
     * @param drawableResId A drawable resource Id.
     * @param size          The desired size (i.e. width and height) of the image icon in pixels.
     *                      Use the lineHeight of the TextView to make the image inline with the
     *                      surrounding text.
     * @param colour        The colour (careful: NOT a resource Id) to apply to the image.
     * @return An ImageSpan, aligned with the bottom of the text.
     */
    private static ImageSpan makeImageSpan(Context context, int drawableResId, int size, int colour) {
        final Drawable drawable = context.getResources().getDrawable(drawableResId);
        drawable.mutate();
        drawable.setColorFilter(colour, PorterDuff.Mode.MULTIPLY);
        drawable.setBounds(0, 0, size, size);
        return new ImageSpan(drawable, ImageSpan.ALIGN_BOTTOM);
    }

}

How to use:

Simply embed references to the desired icons in the text. It doesn't matter whether the text is set programatically through textView.setText(R.string.string_resource); or if it's set in xml.

To embed a drawable icon named example.png, include the following string in the text: [img src=example/].

For example, a string resource might look like this:

<string name="string_resource">This [img src=example/] is an icon.</string>

for Axis2 client this may be helpful

...
serviceStub = new TestBeanServiceStub("<WEB SERVICE URL>"); // Set your value
HttpTransportProperties.Authenticator basicAuthenticator = new HttpTransportProperties.Authenticator();
List<String> authSchemes = new ArrayList<String>();
authSchemes.add(Authenticator.BASIC);
basicAuthenticator.setAuthSchemes(authSchemes); 
basicAuthenticator.setUsername("<UserName>"); // Set your value
basicAuthenticator.setPassword("<Password>"); // Set your value
basicAuthenticator.setPreemptiveAuthentication(true);
serviceStub._getServiceClient().getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE, basicAuthenticator);
serviceStub._getServiceClient().getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.CHUNKED, "false");
...

Another example, which is really a variation of another answer, in that it uses a dictionary too:

>>> vr={} 
... for num in range(1,4): 
...     vr[str(num)] = 5 + num
...     
>>> print vr["3"]
8
>>> 

Check whether your phone supports the video format or not.Even I had the problem when playing a 3gp file but it played a mp4 file perfectly.

If you have more than this in javascript consider some javascript library, e.g. jquery which takes away a little speed, but gives you more readable code.

Your question's code via jquery:

$("td").hide();

Of course there are other javascript libraries out there, as this comparison on wikipedia shows.

Do not forget check the bindings-related code too. So if you wrote:

BasicHttpBinding binding = new BasicHttpBinding();

Be sure that all your app.config files contains

<endpoint address="..."
          binding="basicHttpBinding" ...

not the

<endpoint address="..."
          binding="wsHttpBinding" ...

or so.

I'd been trying to build a menu (in Camping and Markaby) using a hash.

Each item has 2 elements: a menu label and a URL, so a hash seemed right, but the '/' URL for 'Home' always appeared last (as you'd expect for a hash), so menu items appeared in the wrong order.

Using an array with each_slice does the job:

['Home', '/', 'Page two', 'two', 'Test', 'test'].each_slice(2) do|label,link|
   li {a label, :href => link}
end

Adding extra values for each menu item (e.g. like a CSS ID name) just means increasing the slice value. So, like a hash but with groups consisting of any number of items. Perfect.

So this is just to say thanks for inadvertently hinting at a solution!

Obvious, but worth stating: I suggest checking if the length of the array is divisible by the slice value.

You don't have JSON. You have a JavaScript data structure consisting of objects, an array, some strings and some numbers.

Use JSON.stringify(object) to turn it into (a string of) JSON text.

I recommend that you use REQUERY the specific combo box whose data you have changed AND that you do it after the Cmd.Close statement. that way, if you were inputing data, that data is also requeried.

DoCmd.Close
Forms![Form_Name]![Combo_Box_Name].Requery

you might also want to point to the recently changed value

Dim id As Integer
id = Me.[Index_Field]
DoCmd.Close
Forms![Form_Name]![Combo_Box_Name].Requery
Forms![Form_Name]![Combo_Box_Name] = id

this example supposes that you opened a form to input data into a secondary table.

let us say you save School_Index and School_Name in a School table and refer to it in a Student table (which contains only the School_Index field). while you are editing a student, you need to associate him with a school that is not in your School table, etc etc

It means maven is not able to download artifacts from repository. Following steps will help you:

1. Go to repository browser and check if artifact exist.

The other answers didn't work for me, I guess something wrong happens between ButterKnife and 3.0.0 alpha5.

However, I found that when I annotated any one sentence, either BUtterKnife or 3.0.0 alpha5, it works normally.

So, you should just avoid the duplication or conflict.

This is my pure HTML & Javascript solution:

var setHeight = function (element, height) {
    if (!element) {;
        return false;
    }
    else {
        var elementHeight = parseInt(window.getComputedStyle(element, null).height, 10),
        toggleButton = document.createElement('a'),
        text = document.createTextNode('...Show more'),
        parent = element.parentNode;

        toggleButton.src = '#';
        toggleButton.className = 'show-more';
        toggleButton.style.float = 'right';
        toggleButton.style.paddingRight = '15px';
        toggleButton.appendChild(text);

        parent.insertBefore(toggleButton, element.nextSibling);

        element.setAttribute('data-fullheight', elementHeight);
        element.style.height = height;
        return toggleButton;
    }
}

var toggleHeight = function (element, height) {
    if (!element) {
        return false;
    }
    else {
        var full = element.getAttribute('data-fullheight'),
        currentElementHeight = parseInt(element.style.height, 10);

        element.style.height = full == currentElementHeight ? height : full + 'px';
    }
}

var toggleText = function (element) {
    if (!element) {
        return false;
    }
    else {
        var text = element.firstChild.nodeValue;
        element.firstChild.nodeValue = text == '...Show more' ? '...Show less' : '...Show more';
    }
}


var applyToggle = function(elementHeight){
    'use strict';
    return function(){
        toggleHeight(this.previousElementSibling, elementHeight);
        toggleText(this);
    }
}


var modifyDomElements = function(className, elementHeight){
    var elements = document.getElementsByClassName(className);
    var toggleButtonsArray = [];


    for (var index = 0, arrayLength = elements.length; index < arrayLength; index++) {
        var currentElement = elements[index];
        var toggleButton = setHeight(currentElement, elementHeight);
        toggleButtonsArray.push(toggleButton);
    }

    for (var index=0, arrayLength=toggleButtonsArray.length; index<arrayLength; index++){
        toggleButtonsArray[index].onclick = applyToggle(elementHeight);
    }
}

You can then call modifyDomElements function to apply text shortening on all the elements that have shorten-text class name. For that you would need to specify the class name and the height that you would want your elements to be shortened to:

modifyDomElements('shorten-text','50px'); 

Lastly, in your your html, just set the class name on the element you would want your text to get shorten:

<div class="shorten-text">Your long text goes here...</div>

Faced this issue of removing the labels in Chartjs now. Looks like the documentation is improved. http://www.chartjs.org/docs/#getting-started-global-chart-configuration

Chart.defaults.global.legend.display = false;

this global settings prevents legends from being shown in all Charts. Since this was enough for me, I used it. I am not sure to how to avoid legends for individual charts.

I believe that the problem is that the WebRequest measures the time only after the request is actually made. If you submit multiple requests to the same address then the ServicePointManager will throttle your requests and only actually submit as many concurrent connections as the value of the corresponding ServicePoint.ConnectionLimit which by default gets the value from ServicePointManager.DefaultConnectionLimit. Application CLR host sets this to 2, ASP host to 10. So if you have a multithreaded application that submits multiple requests to the same host only two are actually placed on the wire, the rest are queued up.

I have not researched this to a conclusive evidence whether this is what really happens, but on a similar project I had things were horrible until I removed the ServicePoint limitation.

Another factor to consider is the DNS lookup time. Again, is my belief not backed by hard evidence, but I think the WebRequest does not count the DNS lookup time against the request timeout. DNS lookup time can show up as very big time factor on some deployments.

And yes, you must code your app around the WebRequest.BeginGetRequestStream (for POSTs with content) and WebRequest.BeginGetResponse (for GETs and POSTSs). Synchronous calls will not scale (I won't enter into details why, but that I do have hard evidence for). Anyway, the ServicePoint issue is orthogonal to this: the queueing behavior happens with async calls too.

Say that you want to count the rows in an existing table:

Use mysql_result with only one parameter set to "0"

Like this:

$string = mysql_result(
          mysql_query("SELECT COUNT(*) FROM database_name.table_name ")
,0);

Put ( ` ) around database_name and table_name

var_dump($string);

// string(1) "5" //if it only has 5 records in the table

Note: if you query for something else like

SELECT * FROM database.table LIMIT 1

and the table has more than one column then you WILL NOT get an array() in your var_dump you will get the first column only

You can also set DirectoryIndex in apache's httpd.conf file.

CentOS keeps this file in /etc/httpd/conf/httpd.conf Debian: /etc/apache2/apache2.conf

Open the file in your text editor and find the line starting with DirectoryIndex

To load landing.html as a default (but index.html if that's not found) change this line to read:

DirectoryIndex  landing.html index.html

I know this thread is a bit old but, I was looking for something similar and could not find it. Here's what I came up with. I create a string object using the .Net String class to expose all the methods normally found if using C#

[System.String]$myString
 $myString = "237801_201011221155.xml"
 $startPos = $myString.LastIndexOf("_") + 1 # Do not include the "_" character
 $subString = $myString.Substring($startPos,$myString.Length - $startPos)

Result: 201011221155.xml

Here is a vbs script that was passed down to me:

Set servicelist = GetObject("winmgmts:").InstancesOf ("Win32_Service")

for each service in servicelist
    sname = lcase(service.name)
    If sname = "NameOfMyService" Then 
        msgbox(sname)
        service.delete ' the internal name of your service
    end if
next

No, that's not possible since assigning it to a derived class reference would be like saying "Base class is a fully capable substitute for derived class, it can do everything the derived class can do", which is not true since derived classes in general offer more functionality than their base class (at least, that's the idea behind inheritance).

You could write a constructor in the derived class taking a base class object as parameter, copying the values.

Something like this:

public class Base {
    public int Data;

    public void DoStuff() {
        // Do stuff with data
    }
}

public class Derived : Base {
    public int OtherData;

    public Derived(Base b) {
        this.Data = b.Data;
        OtherData = 0; // default value
    }

    public void DoOtherStuff() {
        // Do some other stuff
    }
}

In that case you would copy the base object and get a fully functional derived class object with default values for derived members. This way you can also avoid the problem pointed out by Jon Skeet:

Base b = new Base();//base class
Derived d = new Derived();//derived class

b.DoStuff();    // OK
d.DoStuff();    // Also OK
b.DoOtherStuff();    // Won't work!
d.DoOtherStuff();    // OK

d = new Derived(b);  // Copy construct a Derived with values of b
d.DoOtherStuff();    // Now works!

Arguably, it is an example of syntactic sugar, since it is implemented as an array anyways (which doesn't mean it's useless) - I prefer passing an array to keep it clear, and also declare methods with arrays of given type. Rather an opinion than an answer, though.

Ad 1. null is not an identifier for a property of the global object, like undefined can be

let x;      // undefined_x000D_
let y=null; // null_x000D_
let z=3;    // has value_x000D_
// 'w'      // is undeclared_x000D_
_x000D_
if(!x) console.log('x is null or undefined');_x000D_
if(!y) console.log('y is null or undefined');_x000D_
if(!z) console.log('z is null or undefined');_x000D_
_x000D_
try { if(w) 0 } catch(e) { console.log('w is undeclared') }_x000D_
// typeof not throw exception for undelared variabels_x000D_
if(typeof w === 'undefined') console.log('w is undefined');

Ad 2. The === check values and types. The == dont require same types and made implicit conversion before comparison (using .valueOf() and .toString()). Here you have all (src):

if

== (its negation !=)

=== (its negation !==)

Right after @mail($email_to, $email_subject, $email_message, $headers);

header('Location: nextpage.php');

Note that you will never see 'Thanks for subscribing to our mailing list'

That should be on the next page, if you echo any text you will get an error because the headers would have been already created, if you want to redirect never return any text, not even a space!

One significant difference is that you can include a function in your SQL queries, but stored procedures can only be invoked with the CALL statement:

UDF Example:

CREATE FUNCTION hello (s CHAR(20))
   RETURNS CHAR(50) DETERMINISTIC
   RETURN CONCAT('Hello, ',s,'!');
Query OK, 0 rows affected (0.00 sec)

CREATE TABLE names (id int, name varchar(20));
INSERT INTO names VALUES (1, 'Bob');
INSERT INTO names VALUES (2, 'John');
INSERT INTO names VALUES (3, 'Paul');

SELECT hello(name) FROM names;
+--------------+
| hello(name)  |
+--------------+
| Hello, Bob!  |
| Hello, John! |
| Hello, Paul! |
+--------------+
3 rows in set (0.00 sec)

Sproc Example:

delimiter //

CREATE PROCEDURE simpleproc (IN s CHAR(100))
BEGIN
   SELECT CONCAT('Hello, ', s, '!');
END//
Query OK, 0 rows affected (0.00 sec)

delimiter ;

CALL simpleproc('World');
+---------------------------+
| CONCAT('Hello, ', s, '!') |
+---------------------------+
| Hello, World!             |
+---------------------------+
1 row in set (0.00 sec)

if qs.count()==1:
        print('cart id exists')
        if ....

else:    
        return render(request,"carts/home.html",{})

Such type of code will also return you the same error this is because of the intents as the return statement should be for else not for if statement.

above code can be changed to

if qs.count()==1:
        print('cart id exists')
        if ....

else:   

return render(request,"carts/home.html",{})

This may solve such issues

You want $.param(): http://api.jquery.com/jQuery.param/

Specifically, you want this:

var data = { one: 'first', two: 'second' };
var result = $.param(data);

When given something like this:

{a: 1, b : 23, c : "te!@#st"}

$.param will return this:

a=1&b=23&c=te!%40%23st

Another solution we can use MySQL IF() conditional function :

UPDATE test
SET  field  = IF(something == 1{CONDITION}, 1 {NEW VALUE}, field)
WHERE `id` = 5

private void button1_Click(object sender, EventArgs e)
{
      Form2 m = new Form2();
      m.Show();
      this.Visible = false;
}

There is no command to do it (like you would do it with MySQL for instance). The number of Redis databases is fixed, and set in the configuration file. By default, you have 16 databases. Each database is identified by a number (not a name).

You can use the following command to know the number of databases:

CONFIG GET databases
1) "databases"
2) "16"

You can use the following command to list the databases for which some keys are defined:

INFO keyspace
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0

Please note that you are supposed to use the "redis-cli" client to run these commands, not telnet. If you want to use telnet, then you need to run these commands formatted using the Redis protocol.

For instance:

*2
$4
INFO
$8
keyspace

$79
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0

You can find the description of the Redis protocol here: http://redis.io/topics/protocol

Sometimes that problem occurs if you already have a branch with the base name.

I tried this:

git checkout -b features/aName origin/features/aName

Unfortunately, I already had a branch named features, and I got the exception of the question asker.

Removing the branch features resolved the problem, the above command worked.

This is some really cool stuff! I needed pretty much the same, but with horizontal gradient from white to transparent. And it is working just fine! Here ist my code:

.gradient{
        /* webkit example */
        background-image: -webkit-gradient(
          linear, right top, left top, from(rgba(255, 255, 255, 1.0)),
          to(rgba(255, 255, 255, 0))
        );

        /* mozilla example - FF3.6+ */
        background-image: -moz-linear-gradient(
          right center,
          rgba(255, 255, 255, 1.0) 20%, rgba(255, 255, 255, 0) 95%
        );

        /* IE 5.5 - 7 */
        filter: progid:DXImageTransform.Microsoft.gradient(
          gradientType=1, startColor=0, endColorStr=#FFFFFF
        );

        /* IE8 uses -ms-filter for whatever reason... */
        -ms-filter: progid:DXImageTransform.Microsoft.gradient(
          gradientType=1, startColor=0, endColoStr=#FFFFFF
        );
    }

To be precise, a ||= b means "if a is undefined or falsy (false or nil), set a to b and evaluate to (i.e. return) b, otherwise evaluate to a".

Others often try to illustrate this by saying that a ||= b is equivalent to a || a = b or a = a || b. These equivalencies can be helpful for understanding the concept, but be aware that they are not accurate under all conditions. Allow me to explain:

• a ||= b ? a || a = b?

  The behavior of these statements differs when a is an undefined local variable. In that case, a ||= b will set a to b (and evaluate to b), whereas a || a = b will raise NameError: undefined local variable or method 'a' for main:Object.

• a ||= b ? a = a || b?

  The equivalency of these statements are often assumed, since a similar equivalence is true for other abbreviated assignment operators (i.e. +=,-=,*=,/=,%=,**=,&=,|=,^=,<<=, and >>=). However, for ||= the behavior of these statements may differ when a= is a method on an object and a is truthy. In that case, a ||= b will do nothing (other than evaluate to a), whereas a = a || b will call a=(a) on a's receiver. As others have pointed out, this can make a difference when calling a=a has side effects, such as adding keys to a hash.

• a ||= b ? a = b unless a??

  The behavior of these statements differs only in what they evaluate to when a is truthy. In that case, a = b unless a will evaluate to nil (though a will still not be set, as expected), whereas a ||= b will evaluate to a.

• a ||= b ? defined?(a) ? (a || a = b) : (a = b)????

  Still no. These statements can differ when a method_missing method exists which returns a truthy value for a. In this case, a ||= b will evaluate to whatever method_missing returns, and not attempt to set a, whereas defined?(a) ? (a || a = b) : (a = b) will set a to b and evaluate to b.

Okay, okay, so what is a ||= b equivalent to? Is there a way to express this in Ruby?

Well, assuming that I'm not overlooking anything, I believe a ||= b is functionally equivalent to... (drumroll)

begin
  a = nil if false
  a || a = b
end

Hold on! Isn't that just the first example with a noop before it? Well, not quite. Remember how I said before that a ||= b is only not equivalent to a || a = b when a is an undefined local variable? Well, a = nil if false ensures that a is never undefined, even though that line is never executed. Local variables in Ruby are lexically scoped.

Fax me some electricity, please?

Because you initialized the top variable to -1 in your constructor, you need to increment the top variable in your push() method before you access the array. Note that I've changed the assignment to use ++top:

public void push(int i) 
{
    if (top == stack.length)
    {
        extendStack();
    }

    stack[++top]= i;
}

That will fix the ArrayIndexOutOfBoundsException you posted about. I can see other issues in your code, but since this is a homework assignment I'll leave those as "an exercise for the reader." :)

VMDK/VMX are VMWare file formats but you can use it with VirtualBox:

1. Create a new Virtual Machine and when asks for a hard disk choose "Use an existing hard disk"
2. Click on the "button with folder and green arrow image on the combo box right" which opens Virtual Media Manager, it looks like this (you can open it directly pressing CTRL+D on main window or in File > Virtual Media Manager menu)...
3. Then you can add the VMDK/VMX hard disk image and setup it for your virtual machine :)

1. Create a template.yml, which is your docker-compose.yml with environment variable.
2. Suppose your environment variables are in a file 'env.sh'
3. Put the below piece of code in a sh file and run it.

source env.sh; rm -rf docker-compose.yml; envsubst < "template.yml" > "docker-compose.yml";

A new file docker-compose.yml will be generated with the correct values of environment variables.

Sample template.yml file:

oracledb:
        image: ${ORACLE_DB_IMAGE}
        privileged: true
        cpuset: "0"
        ports:
                - "${ORACLE_DB_PORT}:${ORACLE_DB_PORT}"
        command: /bin/sh -c "chmod 777 /tmp/start; /tmp/start"
        container_name: ${ORACLE_DB_CONTAINER_NAME}

Sample env.sh file:

#!/bin/bash 
export ORACLE_DB_IMAGE=<image-name> 
export ORACLE_DB_PORT=<port to be exposed> 
export ORACLE_DB_CONTAINER_NAME=ORACLE_DB_SERVER

I dont know if you can select a specific number of columns?

For me, I was having the same issue, the issue was that there was an unused RecyclerView in xml with view gone but I am not binding it to any adapter in Activity, hence the issue. It was solved as soon as I removed such unused recycler views in xml

i.e - I removed this view as this was not called in code or any adapter has been set

<android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/rv_profileview_allactivities"
        android:visibility="gone" />

In my development I found two distinct advantages for using an SPA. That is not to say that the following can not be achieved in a traditional web app just that I see incremental benefit without introducing additional disadvantages.

• Potential for less server request as rendering new content isn’t always or even ever an http server request for a new html page. But I say potential because new content could easily require an Ajax call to pull in data but that data could be incrementally lighter than the itself plus markup providing a net benefit.

• The ability to maintain “State”. In its simplest terms, set a variable on entry to the app and it will be available to other components throughout the user’s experience without passing it around or setting it to a local storage pattern. Intelligently managing this ability however is key to keep the top level scope uncluttered.

Other than requiring JS (which is not a crazy thing to require of web apps) other noted disadvantages are in my opinion either not specific to SPA or can be mitigated through good habits and development patterns.

Use the strstr function.

<?php
$myString = "Posted On April 6th By Some Dude";
$result = strstr($myString, 'By', true);

echo $result ;

The third parameter true tells the function to return everything before first occurrence of the second parameter.

Just call .getClass() on each Object in a loop.

Unfortunately, Java doesn't have map(). :)

Also the corresponding API should be enabled for the given project

In Linux and Mac there are not default shortcuts, so try to set your custom shortcut and be careful about don't choose a hotkey used (For example, CTRL+U is taken for uncomment)

1. File-> Preferences -> Keyboard Shortcuts.
2. Type 'transfrom' in the search input to find transform shortcuts.
3. Edit your key combination.

In my case I have CTRL+U CTRL+U for transform to uppercase and CTRL+L CTRL+L for transform to lowercase

Just in case, for Mac instead of CTRL I used ?

In spanish keyboard without changing anything I can make a comment with the keys:

cmd + -

OR

cmd + alt + -

This works because in english keyboard / is located at the same place than - on a spanish keyboard

I had the same problem, I solved changing the ports.

Hope this helps you to understand what is happening.

You will need an intermediate class which will buffer between. Each time InputStream.read(byte[]...) is called, the buffering class will fill the passed in byte array with the next chunk passed in from OutputStream.write(byte[]...). Since the sizes of the chunks may not be the same, the adapter class will need to store a certain amount until it has enough to fill the read buffer and/or be able to store up any buffer overflow.

This article has a nice breakdown of a few different approaches to this problem:

http://blog.ostermiller.org/convert-java-outputstream-inputstream

• suppose you have an array like

   const arr = [1, 2, 3, 4, 5, 6, 7, 8, 9]
    
    
    arr.map((myArr, index) => {
      console.log(`your index is -> ${index} AND value is ${myArr}`);
    })

> output will be
 index is -> 0 AND value is 1
 index is -> 1 AND value is 2
 index is -> 2 AND value is 3
 index is -> 3 AND value is 4
 index is -> 4 AND value is 5
 index is -> 5 AND value is 6
 index is -> 6 AND value is 7
 index is -> 7 AND value is 8
 index is -> 8 AND value is 9

I have the following code which maybe could help:

set.seed(123)
n <- 1000
u <- runif(n) #creates U
x <- -log(u)
y <- runif(n, max=u*sqrt((2*exp(1))/pi)) #create Y
z <- ifelse (y < dnorm(x)/2, -x, NA)
z <- ifelse ((y > dnorm(x)/2) & (y < dnorm(x)), x, z)
z <- z[!is.na(z)]

Be sure to check out verilog-mode and especially verilog-auto. http://www.veripool.org/wiki/verilog-mode/ It is a verilog mode for emacs, but plugins exist for vi(m?) for example.

An instantiation can be automated with AUTOINST. The comment is expanded with M-x verilog-auto and can afterwards be manually edited.

subcomponent subcomponent_instance_name(/*AUTOINST*/);

Expanded

subcomponent subcomponent_instance_name (/*AUTOINST*/
  //Inputs

  .data_rx      (data_rx_1[9:0]),
  //Outputs

);

Implicit wires can be automated with /*AUTOWIRE*/. Check the link for further information.

a = [(0,2), (4,3), (9,9), (10,-1)]
print(list(map(lambda item: item[1], a)))

I have checked the links in Gumbo's answer, and I wanted to paste some part of those things here to exist on Stack Overflow as well.

"...Some people are under the misconception that Unicode is simply a 16-bit code where each character takes 16 bits and therefore there are 65,536 possible characters. This is not, actually, correct. It is the single most common myth about Unicode, so if you thought that, don't feel bad.

In fact, Unicode has a different way of thinking about characters, and you have to understand the Unicode way of thinking of things or nothing will make sense.

Until now, we've assumed that a letter maps to some bits which you can store on disk or in memory:

A -> 0100 0001

In Unicode, a letter maps to something called a code point which is still just a theoretical concept. How that code point is represented in memory or on disk is a whole other story..."

"...Every platonic letter in every alphabet is assigned a magic number by the Unicode consortium which is written like this: U+0639. This magic number is called a code point. The U+ means "Unicode" and the numbers are hexadecimal. U+0639 is the Arabic letter Ain. The English letter A would be U+0041...."

"...OK, so say we have a string:

Hello

which, in Unicode, corresponds to these five code points:

U+0048 U+0065 U+006C U+006C U+006F.

Just a bunch of code points. Numbers, really. We haven't yet said anything about how to store this in memory or represent it in an email message..."

"...That's where encodings come in.

The earliest idea for Unicode encoding, which led to the myth about the two bytes, was, hey, let's just store those numbers in two bytes each. So Hello becomes

00 48 00 65 00 6C 00 6C 00 6F

Right? Not so fast! Couldn't it also be:

48 00 65 00 6C 00 6C 00 6F 00 ? ..."

The problem is, SelectList works as designed. The bug is in the design. You may set the Selected Property in SelectedItem, but this will completely be ignored, if you traverse the list with the GetEnumerator() (or if Mvc does that for you). Mvc will create new SelectListItems instead.

You have to use the SelectList ctor with the SelectListItem[], the Text-Name, the Value-Name and the SelectedValue. Be aware to pass as SelectedValue the VALUE of SelectListItem, which you want to be selected, not the SelectListItem itself! Example:

SelectList sl = new SelectList( new[]{
  new SelectListItem{ Text="one", Value="1"},
  new SelectListItem{ Text="two", Value="2"},
  new SelectListItem{ Text="three", Value="3"}
}, "Text", "Value", "2" );

(not tested this, but I had the same problem)

then the 2nd option will get the selected="selected" attribute. That looks like good old DataSets ;-)

GO ends a batch, you would only very rarely need to use it in code. Be aware that if you use it in a stored proc, no code after the GO will be executed when you execute the proc.

BEGIN and END are needed for any procedural type statements with multipe lines of code to process. You will need them for WHILE loops and cursors (which you will avoid if at all possible of course) and IF statements (well techincally you don't need them for an IF statment that only has one line of code, but it is easier to maintain the code if you always put them in after an IF). CASE statements also use an END but do not have a BEGIN.

for making uppercase from lowercase to upper just use

"string".upper()

where "string" is your string that you want to convert uppercase

for this question concern it will like this:

s.upper()

for making lowercase from uppercase string just use

"string".lower()

where "string" is your string that you want to convert lowercase

for this question concern it will like this:

s.lower()

If you want to make your whole string variable use

s="sadf"
# sadf

s=s.upper()
# SADF

You can also wrap your text in label fields, so your form will be more self-explainable semantically.

Just remember to float labels and inputs to the left and to add a specific width to them, and the containing form. Then you can add margins to both of them, to adjust the spacing between the lines (you understand, of course, that this is a pretty minimal markup that expects content to be as big as to some limit).

That way you wont have to add any more elements, just the label-input pairs, all of them wrapped in a form element.

For example:

<form>
<label for="txtName">Name</label>
<input id"txtName" type="text">
<label for="txtEmail">Email</label>
<input id"txtEmail" type="text">
<label for="txtAddress">Address</label>
<input id"txtAddress" type="text">
...
<input type="submit" value="Submit The Form">
</form>

And the css will be:

form{
float:left; /*to clear the floats of inner elements,usefull if you wanna add a border or background image*/
width:300px;
}
label{
float:left;
width:150px;
margin-bottom:10px; /*or whatever you want the spacing to be*/
}
input{
float:left;
width:150px;
margin-bottom:10px; /*or whatever you want the spacing to be*/
}

Here is a way to remove a specific commit id knowing only the commit id you would like to remove.

git rebase --onto commit-id^ commit-id

Note that this actually removes the change that was introduced by the commit.

You make the http request

HttpResponse response = httpclient.execute(httpget);           
HttpEntity entity = response.getEntity();

inputStream = entity.getContent();

BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8);
            StringBuilder sb = new StringBuilder();

You read the Buffer

String line = null;
while ((line = reader.readLine()) != null)
{
sb.append(line + "\n");
}
Log.d("Result", sb.toString());
result = sb.toString();

Create a JSONObject and pass the result string to the constructor:

JSONObject json = new JSONObject(result);

Parse the json results to your desired variables:

String usuario= json.getString("usuario");
int idperon = json.getInt("idperson");
String nombre = json.getString("nombre");

Do not forget to import:

import org.json.JSONObject;

svn co svn://path destination

To specify current directory, use a "." for your destination directory:

svn checkout file:///home/landonwinters/svn/waterproject/trunk .

Execute these series of commands (insert, update, and install) and you are all set to go.

1. First add the repository:

   sudo add-apt-repository ppa:webupd8team/java
   

2. Update:

   sudo apt-get update
   

3. Install:

   sudo apt-get install oracle-java7-installer
   

I am writing this solution for those who are still facing such issue and cant find the solution.

in my case, I am using

shared hosting (Cpanel Access) Linux CentOS.

I was facing this issue

No module named '_ssl'

I tried for all possible solutions but as you know sometimes things don't work for you and in hosting you don't have access to fully root and run queries. even my hosting provider did for me.. but NO GOOD RESULT.

so how I solved if you are using shared hosting and you have deployed your Django App using

Setup Python App

You only have to downgrade your Python Version, I downgraded from

Python 3.7.3

(As Python 3.7 does not have SSL module in it) To

Python 3.6.8

Hope it will be helpful for someone with the same issue,

There are two types of measurements you can use for specifying widths, heights, margins etc: relative and fixed.

Relative

An example of a relative measurement is percentages, which you have used. Percentages are relevant to their containing element. If there is no containing element they are relative to the window.

<div style="width:100%"> 
<!-- This div will be the full width of the browser, whatever size it is -->
    <div style="width:300px">
    <!-- this div will be 300px, whatever size the browser is -->
        <p style="width:50%">
            This paragraph's width will be 50% of it's parent (150px).
        </p>
    </div>
</div>

Another relative measurement is ems which are relative to font size.

Fixed

An example of a fixed measurement is pixels but a fixed measurement can also be pt (points), cm (centimetres) etc. Fixed (sometimes called absolute) measurements are always the same size. A pixel is always a pixel, a centimetre is always a centimetre.

If you were to use fixed measurements for your sizes the browser size wouldn't affect the layout.

Well, your code is not reproducible so we will never know for sure, but this is what help('break')says:

break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop.

So yes, break only breaks the current loop. You can also see it in action with e.g.:

for (i in 1:10)
{
    for (j in 1:10)
    {
        for (k in 1:10)
        {
            cat(i," ",j," ",k,"\n")
            if (k ==5) break
        }   
    }
}

My problem was that the old assemblies were in the _bin_deployableAssemblies folder under the Web Application. This meant the old assemblies were overwriting the GAC assemblies when building the project.

ServicePointManager.ServerCertificateValidationCallback isn't supported in .Net Core.

Current situation is that it will be a a new ServerCertificateCustomValidationCallback method for the upcoming 4.1.* System.Net.Http contract (HttpClient). .NET Core team are finalizing the 4.1 contract now. You can read about this in here on github

You can try out the pre-release version of System.Net.Http 4.1 by using the sources directly here in CoreFx or on the MYGET feed: https://dotnet.myget.org/gallery/dotnet-core

Use the audio.js which is a polyfill for the <audio> tag with fallback to flash.

In general, look at https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills for polyfills to the HTML 5 APIs.. (it includes more <audio> polyfills)

LINQ is slower now, but it might get faster at some point. The good thing about LINQ is that you don't have to care about how it works. If a new method is thought up that's incredibly fast, the people at Microsoft can implement it without even telling you and your code would be a lot faster.

More importantly though, LINQ is just much easier to read. That should be enough reason.
