In order to get new refresh_token each time on authentication the type of OAuth 2.0 credentials created in the dashboard should be "Other". Also as mentioned above the access_type='offline' option should be used when generating the authURL.

When using credentials with type "Web application" no combination of prompt/approval_prompt variables will work - you will still get the refresh_token only on the first request.

There is no event raised when a class changes. The alternative is to manually raise an event when you programatically change the class:

$someElement.on('event', function() {
    $('#myDiv').addClass('submission-ok').trigger('classChange');
});

// in another js file, far, far away
$('#myDiv').on('classChange', function() {
     // do stuff
});

UPDATE

This question seems to be gathering some visitors, so here is an update with an approach which can be used without having to modify existing code using the new MutationObserver:

var $div = $("#foo");_x000D_
var observer = new MutationObserver(function(mutations) {_x000D_
  mutations.forEach(function(mutation) {_x000D_
    if (mutation.attributeName === "class") {_x000D_
      var attributeValue = $(mutation.target).prop(mutation.attributeName);_x000D_
      console.log("Class attribute changed to:", attributeValue);_x000D_
    }_x000D_
  });_x000D_
});_x000D_
observer.observe($div[0], {_x000D_
  attributes: true_x000D_
});_x000D_
_x000D_
$div.addClass('red');

.red { color: #C00; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="foo" class="bar">#foo.bar</div>

Be aware that the MutationObserver is only available for newer browsers, specifically Chrome 26, FF 14, IE 11, Opera 15 and Safari 6. See MDN for more details. If you need to support legacy browsers then you will need to use the method I outlined in my first example.

Adding to Dmitri Chebotarev Answer,

If you want to alter multiple columns at a time , you can do it like below

DB::statement('
     ALTER TABLE `events` 
            MODIFY `event_date` DATE NOT NULL,
            MODIFY `event_start_time` TIME NOT NULL,
            MODIFY `event_end_time` TIME NOT NULL;
');

This would be a pure JS version (adapted from cowboy's):

var obj = {a: 123, b: "4 5 6"};
var data = "text/json;charset=utf-8," + encodeURIComponent(JSON.stringify(obj));

var a = document.createElement('a');
a.href = 'data:' + data;
a.download = 'data.json';
a.innerHTML = 'download JSON';

var container = document.getElementById('container');
container.appendChild(a);

Using 'minifyEnabled' instead of 'runProguard' works properly.

Previous code:

buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

Current code:

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }

Hope this helps.

I had the same problem.

This php setting solved my problem:

allow_url_fopen -> 1

filenames must sort correctly to combine correctly!

file1.bin file2.bin ... file10.bin wont work properly

file01.bin file02.bin ... file10.bin will work properly

c:>for %i in (file*.bin) do type %i >> onebinary.bin

Works for ascii or binary files.

Before we try to solve the invalid character problem, the lack of curly braces around the if and else if statements is wreaking havoc on your program's logic. Change it to this:

if (personPlay.equals(computerPlay)) {
   System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
   if (computerPlay.equals("S")) 
      System.out.println("Rock crushes scissors. You win!!");
   else if (computerPlay.equals("P")) 
        System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
   if (computerPlay.equals("S")) 
       System.out.println("Scissor cuts paper. You lose!!"); 
   else if (computerPlay.equals("R")) 
        System.out.println("Paper eats rock. You win!!");
} 
else if (personPlay.equals("S")) {
     if (computerPlay.equals("P")) 
         System.out.println("Scissor cuts paper. You win!!"); 
     else if (computerPlay.equals("R")) 
        System.out.println("Rock breaks scissors. You lose!!");
}
else 
     System.out.println("Invalid user input.");

Much clearer! It's now actually a piece of cake to catch the bad characters. You need to move the else statement to somewhere that will catch the errors before you attempt to process anything else. So change everything to:

if( /* insert your check for bad characters here */ ) { 
     System.out.println("Invalid user input.");
}
else if (personPlay.equals(computerPlay)) {
   System.out.println("It's a tie!");
}
else if (personPlay.equals("R")) {
   if (computerPlay.equals("S")) 
      System.out.println("Rock crushes scissors. You win!!");
   else if (computerPlay.equals("P")) 
        System.out.println("Paper eats rock. You lose!!");
}
else if (personPlay.equals("P")) {
   if (computerPlay.equals("S")) 
       System.out.println("Scissor cuts paper. You lose!!"); 
   else if (computerPlay.equals("R")) 
        System.out.println("Paper eats rock. You win!!");
} 
else if (personPlay.equals("S")) {
     if (computerPlay.equals("P")) 
         System.out.println("Scissor cuts paper. You win!!"); 
     else if (computerPlay.equals("R")) 
        System.out.println("Rock breaks scissors. You lose!!");
}

If it's to validate method parameters, none of the solutions throw ArgumentOutOfRangeException and allow easy/proper configuration of inclusive/exclusive min/max values.

Use like this

public void Start(int pos)
{
    pos.CheckRange(nameof(pos), min: 0);

    if (pos.IsInRange(max: 100, maxInclusive: false))
    {
        // ...
    }
}

I just wrote these beautiful functions. It also has the advantage of having no branching (a single if) for valid values. The hardest part is to craft the proper exception messages.

/// <summary>
/// Returns whether specified value is in valid range.
/// </summary>
/// <typeparam name="T">The type of data to validate.</typeparam>
/// <param name="value">The value to validate.</param>

/// <param name="minInclusive">Whether the minimum value is valid.</param>
/// <param name="max">The maximum valid value.</param>
/// <param name="maxInclusive">Whether the maximum value is valid.</param>
/// <returns>Whether the value is within range.</returns>
public static bool IsInRange<T>(this T value, T? min = null, bool minInclusive = true, T? max = null, bool maxInclusive = true)
    where T : struct, IComparable<T>
{
    var minValid = min == null || (minInclusive && value.CompareTo(min.Value) >= 0) || (!minInclusive && value.CompareTo(min.Value) > 0);
    var maxValid = max == null || (maxInclusive && value.CompareTo(max.Value) <= 0) || (!maxInclusive && value.CompareTo(max.Value) < 0);
    return minValid && maxValid;
}

public static T CheckRange<T>(this T value, string name, T? min = null, bool minInclusive = true, T? max = null, bool maxInclusive = true)
where T : struct, IComparable<T>
{
    if (!value.IsInRange(min, minInclusive, max, maxInclusive))
    {
        if (min.HasValue && minInclusive && max.HasValue && maxInclusive)
        {
            var message = "{0} must be between {1} and {2}.";
            throw new ArgumentOutOfRangeException(name, value, message.FormatInvariant(name, min, max));
        }
        else
        {
            var messageMin = min.HasValue ? GetOpText(true, minInclusive).FormatInvariant(min) : null;
            var messageMax = max.HasValue ? GetOpText(false, maxInclusive).FormatInvariant(max) : null;
            var message = (messageMin != null && messageMax != null) ?
                "{0} must be {1} and {2}." :
                "{0} must be {1}.";
            throw new ArgumentOutOfRangeException(name, value, message.FormatInvariant(name, messageMin ?? messageMax, messageMax));
        }
    }
    return value;
}

private static string GetOpText(bool greaterThan, bool inclusive)
{
    return (greaterThan && inclusive) ? "greater than or equal to {0}" :

Might be better to use a choice, don't have to type (or possibly mistype) your expressions more than once, and allows you to follow additional different behaviors.

I very often use count(/html/body) = 0, as the specific number of nodes is more interesting than the set. For example... when there is unexpectedly more than 1 node that matches your expression.

<xsl:choose>
    <xsl:when test="/html/body">
         <!-- Found the node(s) -->
    </xsl:when>
    <!-- more xsl:when here, if needed -->
    <xsl:otherwise>
         <!-- No node exists -->
    </xsl:otherwise>
</xsl:choose>

Looks like this behavior is how Ansible currently works, although there is a lot of interest in fixing it to work as desired. There's currently a pull request with the desired functionality so hopefully this will get incorporated into Ansible eventually.

This one shows SQL that is currently "ACTIVE":-

select S.USERNAME, s.sid, s.osuser, t.sql_id, sql_text
from v$sqltext_with_newlines t,V$SESSION s
where t.address =s.sql_address
and t.hash_value = s.sql_hash_value
and s.status = 'ACTIVE'
and s.username <> 'SYSTEM'
order by s.sid,t.piece
/

This shows locks. Sometimes things are going slow, but it's because it is blocked waiting for a lock:

select
  object_name, 
  object_type, 
  session_id, 
  type,         -- Type or system/user lock
  lmode,        -- lock mode in which session holds lock
  request, 
  block, 
  ctime         -- Time since current mode was granted
from
  v$locked_object, all_objects, v$lock
where
  v$locked_object.object_id = all_objects.object_id AND
  v$lock.id1 = all_objects.object_id AND
  v$lock.sid = v$locked_object.session_id
order by
  session_id, ctime desc, object_name
/

This is a good one for finding long operations (e.g. full table scans). If it is because of lots of short operations, nothing will show up.

COLUMN percent FORMAT 999.99 

SELECT sid, to_char(start_time,'hh24:mi:ss') stime, 
message,( sofar/totalwork)* 100 percent 
FROM v$session_longops
WHERE sofar/totalwork < 1
/

Use a Macro.

Macro>Start Recording

Use the keyboard to make your changes in a repeatable manner e.g.

home>type "able">end>down arrow>home

Then go back to the menu and click stop recording then run a macro multiple times.

That should do it and no regex based complications!

To properly select the elements using the logical operations that you've stated, you just need jQuery.filter() for the AND operation, not "special filter functions". You also need jQuery.add() for the OR operation.

var elements = $('[myc="blue"]').filter('[myid="1"').add('[myid="3"');

Alternatively, it is possible to accomplish using shorthand in a single selector, where jamming selectors together acts as an AND and separating with a comma acts as an OR:

var elements = $('[myc="blue"][myid="1"], [myid="3"]');

This seems to work, though possibly cumbersome for large lists.

>>> A = [0, 1]
>>> B = [1, 0]
>>> C = [0, 2]
>>> not sum([not i in A for i in B])
True
>>> not sum([not i in A for i in C])
False
>>> 

However, if each list must contain all the elements of other then the above code is problematic.

>>> A = [0, 1, 2]
>>> not sum([not i in A for i in B])
True

The problem arises when len(A) != len(B) and, in this example, len(A) > len(B). To avoid this, you can add one more statement.

>>> not sum([not i in A for i in B]) if len(A) == len(B) else False
False

One more thing, I benchmarked my solution with timeit.repeat, under the same conditions used by Aaron Hall in his post. As suspected, the results are disappointing. My method is the last one. set(x) == set(y) it is.

>>> def foocomprehend(): return not sum([not i in data for i in data2])
>>> min(timeit.repeat('fooset()', 'from __main__ import fooset, foocount, foocomprehend'))
25.2893661496
>>> min(timeit.repeat('foosort()', 'from __main__ import fooset, foocount, foocomprehend'))
94.3974742993
>>> min(timeit.repeat('foocomprehend()', 'from __main__ import fooset, foocount, foocomprehend'))
187.224562545

Use the stringInsert function rather than the putinplace function. I was using the later function to parse a mysql query. Although the output looked alright, the query resulted in a error which took me a while to track down. The following is my version of the stringInsert function requiring only one parameter.

function stringInsert($str,$insertstr,$pos)
{
    $str = substr($str, 0, $pos) . $insertstr . substr($str, $pos);
    return $str;
}  

See any reference manual, such as the man page:

f,F

The double argument is rounded and converted to decimal notation in the style [-]ddd.ddd, where the number of digits after the decimal-point character is equal to the precision specification. If the precision is missing, it is taken as 6; if the precision is explicitly zero, no decimal-point character appears. If a decimal point appears, at least one digit appears before it. (The SUSv2 does not know about F and says that character string representations for infinity and NaN may be made available. The C99 standard specifies '[-]inf' or '[-]infinity' for infinity, and a string starting with 'nan' for NaN, in the case of f conversion, and '[-]INF' or '[-]INFINITY' or 'NAN*' in the case of F conversion.)

g,G

The double argument is converted in style f or e (or F or E for G conversions). The precision specifies the number of significant digits. If the precision is missing, 6 digits are given; if the precision is zero, it is treated as 1. Style e is used if the exponent from its conversion is less than -4 or greater than or equal to the precision. Trailing zeros are removed from the fractional part of the result; a decimal point appears only if it is followed by at least one digit.

Codeigniter has a function that retrieves your base path which is:

FCPATH and BASEPATH i recommand use FCPATH.

for your base url use:

<?=base_url()?>

if your php short tag is off

<?php echo base_url(); ?>

for example: if you want to link you css files which is in your base path

<script src='<?=base_url()?>js/jquery.js' type='text/javascript' />

basically object and instance are the two words used interchangeably. A class is template for an object and an object is an instance of a class.

Try this solution:

Go to->

1. xammp ->htdocs-> then open index.php from the htdocs folder
2. you can modify the dashboard
3. restart the server

Example Code index.php :

    <?php
    if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {
        $uri = 'https://';
    } else {
        $uri = 'http://';
    }
    $uri .= $_SERVER['HTTP_HOST'];
    header('Location: '.$uri.'/dashboard/');
    exit;
   ?>

As drew_w said, you can find a good example here.

JSFIDDLE

First Google hit says:

this is usually a mismatch in the client/server bindings, where the message version in the service uses SOAP 1.2 (which expects application/soap+xml) and the version in the client uses SOAP 1.1 (which sends text/xml). WSHttpBinding uses SOAP 1.2, BasicHttpBinding uses SOAP 1.1.

It usually seems to be a wsHttpBinding on one side and a basicHttpBinding on the other.

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

On my projects i give all rows the class "borders" which I want it to display more like a table with even borders. Giving each child element a border on the bottom and right and the first element of each row a left border will make all of your boxes have an even border:

First give all of the rows children a border on the right and bottom

.borders div{
    border-right:1px solid #999;
    border-bottom:1px solid #999;
}

Next give the first child of each or a left border

.borders div:first-child{
    border-left:
    1px solid #999;
}

Last make sure to clear the borders for their child elements

.borders div > div{
    border:0;
}

HTML:

<div class="row borders">
    <div class="col-xs-5 col-md-2">Email</div>
    <div class="col-xs-7 col-md-4">[email protected]</div>
    <div class="col-xs-5 col-md-2">Phone</div>
    <div class="col-xs-7 col-md-4">555-123-4567</div>
</div>

You can use Tommy's method in forms as well:

@using (Html.BeginForm("Action", "Controller", FormMethod.Get, new { target = "_blank" }))
{
//code
}

SnackBar is definitely the right class to use, as pointed out by Darky.

One tricky thing about showSnackBar is getting to the ScaffoldState, if you're trying to call showSnackBar within the build method where you construct your Scaffold.

You might see an error like this, which includes some text explaining how to solve the problem.

--¦ EXCEPTION CAUGHT BY GESTURE ¦-------------------------------------------------------------------
The following assertion was thrown while handling a gesture:
Scaffold.of() called with a context that does not contain a Scaffold.
No Scaffold ancestor could be found starting from the context that was passed to Scaffold.of(). This
usually happens when the context provided is from the same StatefulWidget as that whose build
function actually creates the Scaffold widget being sought.
There are several ways to avoid this problem. The simplest is to use a Builder to get a context that
is "under" the Scaffold. For an example of this, please see the documentation for Scaffold.of():
  https://docs.flutter.io/flutter/material/Scaffold/of.html
A more efficient solution is to split your build function into several widgets. This introduces a
new context from which you can obtain the Scaffold. In this solution, you would have an outer widget
that creates the Scaffold populated by instances of your new inner widgets, and then in these inner
widgets you would use Scaffold.of().
A less elegant but more expedient solution is assign a GlobalKey to the Scaffold, then use the
key.currentState property to obtain the ScaffoldState rather than using the Scaffold.of() function.
The context used was:

You can either pass a GlobalKey to your Scaffold constructor:

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final key = new GlobalKey<ScaffoldState>();
    return new Scaffold(
      key: key,
      floatingActionButton: new Builder(
        builder: (BuildContext context) {
          return new FloatingActionButton(
            onPressed: () {
              key.currentState.showSnackBar(new SnackBar(
                content: new Text("Sending Message"),
              ));
            },
            tooltip: 'Increment',
            child: new Icon(Icons.add),
          );
        }
      ),
    );
  }
}

Or you can use a Builder to create a BuildContext that is a child of the Scaffold.

class MyHomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      floatingActionButton: new Builder(
        builder: (BuildContext context) {
          return new FloatingActionButton(
            onPressed: () {
              Scaffold.of(context).showSnackBar(new SnackBar(
                content: new Text("Sending Message"),
              ));
            },
            tooltip: 'Increment',
            child: new Icon(Icons.add),
          );
        }
      ),
    );
  }
}

Finally, you could split your widget into multiple classes, which is the best long-term approach.

What happens if I promote the column to be a/the PK, too (a.k.a. identifying relationship)? As the column is now the PK, I must tag it with @Id (...).

This enhanced support of derived identifiers is actually part of the new stuff in JPA 2.0 (see the section 2.4.1 Primary Keys Corresponding to Derived Identities in the JPA 2.0 specification), JPA 1.0 doesn't allow Id on a OneToOne or ManyToOne. With JPA 1.0, you'd have to use PrimaryKeyJoinColumn and also define a Basic Id mapping for the foreign key column.

Now the question is: are @Id + @JoinColumn the same as just @PrimaryKeyJoinColumn?

You can obtain a similar result but using an Id on OneToOne or ManyToOne is much simpler and is the preferred way to map derived identifiers with JPA 2.0. PrimaryKeyJoinColumn might still be used in a JOINED inheritance strategy. Below the relevant section from the JPA 2.0 specification:

11.1.40 PrimaryKeyJoinColumn Annotation

The PrimaryKeyJoinColumn annotation specifies a primary key column that is used as a foreign key to join to another table.

The PrimaryKeyJoinColumn annotation is used to join the primary table of an entity subclass in the JOINED mapping strategy to the primary table of its superclass; it is used within a SecondaryTable annotation to join a secondary table to a primary table; and it may be used in a OneToOne mapping in which the primary key of the referencing entity is used as a foreign key to the referenced entity^[108].

...

If no PrimaryKeyJoinColumn annotation is specified for a subclass in the JOINED mapping strategy, the foreign key columns are assumed to have the same names as the primary key columns of the primary table of the superclass.

...

Example: Customer and ValuedCustomer subclass

@Entity
@Table(name="CUST")
@Inheritance(strategy=JOINED)
@DiscriminatorValue("CUST")
public class Customer { ... }

@Entity
@Table(name="VCUST")
@DiscriminatorValue("VCUST")
@PrimaryKeyJoinColumn(name="CUST_ID")
public class ValuedCustomer extends Customer { ... }

_{[108] The derived id mechanisms described in section 2.4.1.1 are now to be preferred over PrimaryKeyJoinColumn for the OneToOne mapping case.}

This source http://weblogs.java.net/blog/felipegaucho/archive/2009/10/24/jpa-join-table-additional-state states that using @ManyToOne and @Id works with JPA 1.x. Who's correct now?

The author is using a pre release JPA 2.0 compliant version of EclipseLink (version 2.0.0-M7 at the time of the article) to write an article about JPA 1.0(!). This article is misleading, the author is using something that is NOT part of JPA 1.0.

For the record, support of Id on OneToOne and ManyToOne has been added in EclipseLink 1.1 (see this message from James Sutherland, EclipseLink comitter and main contributor of the Java Persistence wiki book). But let me insist, this is NOT part of JPA 1.0.

Important Update:

HttpModule and Http from @angular/http has been deprecated since Angular V5, should of using HttpClientModule and HttpClient from @angular/common/http instead, refer CHANGELOG.

For Angular version previous from **@4.3.0, You should inject Http from @angular/http, and HttpModule is for importing at your NgModule's import array.

import {HttpModule} from '@angular/http';

@NgModule({
  ...
  imports: [HttpModule]
})

Inject http at component or service

import { Http } from '@angular/http';

constructor(private http: Http) {}

For Angular version after(include) 4.3.0, you can use HttpClient from @angular/common/http instead of Http from @angular/http. Don't forget to import HttpClientModule at your NgModule's import array first.

If you're looking for something as nice as Python's x[-1] notation, I think you're out of luck. The standard idiom is

x[length(x)]  

but it's easy enough to write a function to do this:

last <- function(x) { return( x[length(x)] ) }

This missing feature in R annoys me too!

If you're on windows you probably want the pywin32 library, which includes pythoncom and a whole lot of other stuff that is pretty standard.

hey first of all to include c++ functions you should use

include<iostream.h> instead of stdio .h

and to hold the output screen there is a simple command getch();
here, is an example:

   #include<iostream.h>
   #include<conio.h>
   void main()  \\or int main(); if you want
  {
    cout<<"c# is more advanced than c++";
    getch();
  }

thank you

Have you already looked at adding a check constraint on that column which would restrict values? Something like:

CREATE TABLE SomeTable
(
   Id int NOT NULL,
   Frequency varchar(200),
   CONSTRAINT chk_Frequency CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))
)

The background color property is ignored on a UINavigationBar, so if you want to adjust the look and feel you either have to use the tintColor or call some of the other methods listed under "Customizing the Bar Appearance" of the UINavigationBar class reference (like setBackgroundImage:forBarMetrics:).

Be aware that the tintColor property works differently in iOS 7, so if you want a consistent look between iOS 7 and prior version using a background image might be your best bet. It's also worth mentioning that you can't configure the background image in the Storyboard, you'll have to create an IBOutlet to your UINavigationBar and change it in viewDidLoad or some other appropriate place.

Apple introduced the topLayoutGuide and bottomLayoutGuide as properties of UIViewController way back in iOS 7. They allowed you to create constraints to keep your content from being hidden by UIKit bars like the status, navigation or tab bar. These layout guides are deprecated in iOS 11 and replaced by a single safe area layout guide.

Refer link for more information.

A simplest fix would be:

x = input("Give starting number: ")
y = input("Give ending number: ")

x = int(x)  # parse string into an integer
y = int(y)  # parse string into an integer

for i in range(x,y):
    print(i)

input returns you a string (raw_input in Python 2). int tries to parse it into an integer. This code will throw an exception if the string doesn't contain a valid integer string, so you'd probably want to refine it a bit using try/except statements.

select * from emp where sal =(select max(sal) from emp where eno in(select eno from emp where sal <(select max(sal)from emp )));

try the above code ....

if you want the third max record then add another nested query "select max(sal)from emp" inside the bracket of the last query and give less than operator in front of it.

simply you can use "novalidate" for < form > tag

Reverse the string, replace the char, reverse the string.

Here is a post for reversing a string in javascript: How do you reverse a string in place in JavaScript?

You can use <script>'s defer attribute. It specifies that the script will be executed when the page has finished parsing.

<script defer src="path/to/yourscript.js">

A nice article about this: http://davidwalsh.name/script-defer

Browser support seems pretty good: http://caniuse.com/#search=defer

Another great article about loading JS using defer and async: https://flaviocopes.com/javascript-async-defer/

    while(i<10){
               $('#Postsoutput').prepend('<div id="first'+i+'">'+i+'</div>');
               /* get the dynamic Div*/
               $('#first'+i).hide(1000);
               $('#first'+i).show(1000);
                i++;
                }

just enter the following command on command prompt after launching the app:

adb shell dumpsys window windows | find "mCurrentFocus"

if executing the command on linux terminal replace find by grep

Forget float, margin and html 3/5. The mail is very obsolete. You need do all with table. One line = one table. You need margin or padding ? Do another column.

Codepen

Example : i need one line with 1 One Picture of 40*40 2 One margin of 10 px 3 One text of 400px

I start my line :

<table style=" background-repeat:no-repeat; width:450px;margin:0;" cellpadding="0" cellspacing="0" border="0">
   <tr style="height:40px; width:450px; margin:0;">
     <td style="height:40px; width:40px; margin:0;">
        <img src="" style="width=40px;height40;margin:0;display:block"
     </td>
     <td style="height:40px; width:10px; margin:0;">        
     </td>
     <td style="height:40px; width:400px; margin:0;">
     <p style=" margin:0;"> my text   </p>
     </td>
   </tr>
</table>

[Edit]

As noted in comments above, while still on some UA implementations, readAsBinaryString method didn't made its way to the specs and should not be used in production. Instead, use readAsArrayBuffer and loop through it's buffer to get back the binary string :

document.querySelector('input').addEventListener('change', function() {_x000D_
_x000D_
  var reader = new FileReader();_x000D_
  reader.onload = function() {_x000D_
_x000D_
    var arrayBuffer = this.result,_x000D_
      array = new Uint8Array(arrayBuffer),_x000D_
      binaryString = String.fromCharCode.apply(null, array);_x000D_
_x000D_
    console.log(binaryString);_x000D_
_x000D_
  }_x000D_
  reader.readAsArrayBuffer(this.files[0]);_x000D_
_x000D_
}, false);

<input type="file" />_x000D_
<div id="result"></div>

For a more robust way to convert your arrayBuffer in binary string, you can refer to this answer.

[old answer] _(modified)

Yes, the file API does provide a way to convert your File, in the <input type="file"/> to a binary string, thanks to the FileReader Object and its method readAsBinaryString.
[But don't use it in production !]

document.querySelector('input').addEventListener('change', function(){_x000D_
    var reader = new FileReader();_x000D_
    reader.onload = function(){_x000D_
        var binaryString = this.result;_x000D_
        document.querySelector('#result').innerHTML = binaryString;_x000D_
        }_x000D_
    reader.readAsBinaryString(this.files[0]);_x000D_
  }, false);

<input type="file"/>_x000D_
<div id="result"></div>

If you want an array buffer, then you can use the readAsArrayBuffer() method :

document.querySelector('input').addEventListener('change', function(){_x000D_
    var reader = new FileReader();_x000D_
    reader.onload = function(){_x000D_
        var arrayBuffer = this.result;_x000D_
      console.log(arrayBuffer);_x000D_
        document.querySelector('#result').innerHTML = arrayBuffer + '  '+arrayBuffer.byteLength;_x000D_
        }_x000D_
    reader.readAsArrayBuffer(this.files[0]);_x000D_
  }, false);

<input type="file"/>_x000D_
<div id="result"></div>

UPDATE for Django >= 1.7

Per Django 2.1 documentation: Serving files uploaded by a user during development

from django.conf import settings
from django.conf.urls.static import static

urlpatterns = patterns('',
    # ... the rest of your URLconf goes here ...
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

You no longer need if settings.DEBUG as Django will handle ensuring this is only used in Debug mode.

ORIGINAL answer for Django <= 1.6

Try putting this into your urls.py

from django.conf import settings

# ... your normal urlpatterns here

if settings.DEBUG:
    # static files (images, css, javascript, etc.)
    urlpatterns += patterns('',
        (r'^media/(?P<path>.*)$', 'django.views.static.serve', {
        'document_root': settings.MEDIA_ROOT}))

With this you can serve the static media from Django when DEBUG = True (when you run on local computer) but you can let your web server configuration serve static media when you go to production and DEBUG = False

For me, none of the above responses worked straight ahead. Instead, I had to do the following (Python 3):

from urllib.request import urlopen

data = urlopen("[your url goes here]").read().decode('utf-8')

# Do what you need to do with the data.

Best way would be to declare Boolean variable within the code block and return it at end of code, like this:

public boolean Test(){
    boolean booleanFlag= true; 
    if (A>B)
    {booleanFlag= true;}
    else 
    {booleanFlag = false;}
    return booleanFlag;

}

I find this the best way.

I wanted to share with you my solution to export a database with Microsoft SQL Server Management Studio.

To Export your database

1. Open a new request
2. Copy paste this script

DECLARE @BackupFile NVARCHAR(255);
SET @BackupFile = 'c:\database-backup_2020.07.22.bak';
PRINT @BackupFile;
BACKUP DATABASE [%databaseName%] TO DISK = @BackupFile;

Don't forget to replace %databaseName% with the name of the database you want to export.

Note that this method gives a lighter file than from the menu.

To import this file from SQL Server Management Studio. Don't forget to delete your database beforehand.

1. Click restore database

2. Add the backup file

3. Validate

Enjoy! :) :)

First add in the head tags:

<script>
   function showDialog(openFileDialog) {
       document.getElementById(openFileDialog).click();
   }
   function fileName(openFileDialog) {
       return document.getElementById(openFileDialog).value;
   }
   function hasFile(openFileDialog) {
       return document.getElementById(openFileDialog).value != "";
   }
   function fileNameWithoutFakePath(openFileDialog) {
       var fileName = document.getElementById(openFileDialog).value;
       return fileName.substr(fileName.lastIndexOf('\\') + 1);
   }
   function fakePathWithoutFileName(openFileDialog) {
       var fileName = document.getElementById(openFileDialog).value;
       return fileName.substr(0, fileName.lastIndexOf('\\'));
   }
</script>

if you already have script tags, just add these functions above.

In your body or form tags adding:

<input type="file" style="display:none" id="yourDesiredOrFavoriteNameForTheNewOpenFileDialogInstance"/>

No matter where in your html, is just like that you've created a new instance of type OpenFileDialog class as global variable, whose name is the id of the element, no matter where in your code or xaml, but in your script or code, you can't type his name, and then read a property or call a function, because there are global functions that do those that are not defined in the element input type="file". You just have to give these functions the id of the hidden input type="file" which is the name of the OpenFileDialog instance as string.

To ease your life in creating open file dialogs instances to your html, you can make a function that does it:

function createAndAddNewOpenFileDialog(name) {
     document.getElementById("yourBodyOrFormId").innerHtml += "<input type='file' style='display:none' id='" + name + "'/>"
}

and if you want to remove open file dialog, then you can make and use the following function:

function removeOpenFileDialog(name) {
    var html = document.getElementById("yourBodyOrFormId").innerHtml;
    html = html.replace("<input type='file' style='display:none' id='" + name + "'/>", "");
    document.getElementById("yourBodyOrFormId").innerHtml = html;
}

but before you remove open file dialog, ensure that it exists by making and using the following function:

function doesOpenFileDialogExist(name) {
    return document.getElementById("yourBodyOrFormId").innerHtml.indexOf("<input type='file' style='display:none' id='" + name + "'/>") != -1
}

and if you don't want to create and add the open file dialogs in the body or form tags in the html, because this is adding hidden input type="file"s, then you can do it in script using the create function above:

function yourBodyOrFormId_onload() {
    createAndAddNewOpenFileDialog("openFileDialog1");
    createAndAddNewOpenFileDialog("openFileDialog2");
    createAndAddNewOpenFileDialog("openFileDialog3");
    createAndAddNewOpenFileDialog("File Upload");
    createAndAddNewOpenFileDialog("Image Upload");
    createAndAddNewOpenFileDialog("bla");
    //etc and rest of your code
}

Ensure that near your body or form tags, you added:

onload="yourBodyOrFormId_onload()"

You don't have to do this line above, if you did it already.

TIP: You can add to your project or website new JScript File, if you don't have yet, and in this file you can put all the open file dialog functions away from the script tags and the html or web form page, and use them in your html or web form page from this JScript file, but don't forget before to link the html or web form page to the JScript File of course. You can do it just by dragging the JScript file to your html page in the head tags. If your page is web form and not simple html, and you don't have head tags, then put it anywhere so that it can work. Don't forget to define global variable in that JScript File, whose value will be your body or form id as string. After you linked the JScript file to your html or web form page, you can onload event of your body of form, set the value of that variable to your body or form id. Then in the JScript File, you don't have to give to the document the id of the body or form of one page anymore, just give it the value of that variable. You can call that variable bodyId or formId or bodyOrFormId or any other name you want.

Good luck man!

You need to be running a mail server locally. If this is Unix, enable sendmail If this is Windows install the Simple Mail Transfer Server (not sure if the name is correct) component of IIs. E.g. for windows 2003 follow this: http://msdn.microsoft.com/en-us/library/8b83ac7t.aspx

castable is documented by W3C here.

When I had this problem, I installed 'Remote Tools for Visual Studio 2015' from MSDN. I attached my local VS to the server to debug.

I appreciate that some folks may not have the ability to either install on or access other servers, but I thought I'd throw it out there as an option.

Parser from html-react-parser is a good solution. You just have to

• install it with npm or yarn
• import Parser from 'html-react-parser';

• call it with :

  <MyComponent text=Parser("This is <strong>not</strong> working.") />
  

  and it works well.

This seems to work:

select your_column  
from your_table  
order by   
case when isnumeric(your_column) = 1 then your_column else 999999999 end,  
your_column   

It's just what it says:

inputFile = open((x), encoding = "utf8", "r")

You have specified encoding as a keyword argument, but "r" as a positional argument. You can't have positional arguments after keyword arguments. Perhaps you wanted to do:

inputFile = open((x), "r", encoding = "utf8")

Just in case you can't / don't use CURLOPT_HEADERFUNCTION or other solutions;

$nextCheck = function($body) {
    return ($body && strpos($body, 'HTTP/') === 0);
};

[$headers, $body] = explode("\r\n\r\n", $result, 2);
if ($nextCheck($body)) {
    do {
        [$headers, $body] = explode("\r\n\r\n", $body, 2);
    } while ($nextCheck($body));
}

1. Implement a slot in your QMainWindow where you will open your new Window,
2. Place a widget on your QMainWindow,
3. Connect a signal from this widget to a slot from the QMainWindow (for example: if the widget is a QPushButton connect the signal click() to the QMainWindow custom slot you have created).

Code example:

MainWindow.h

// ...
include "newwindow.h"
// ...
public slots:
   void openNewWindow();
// ...
private:
   NewWindow *mMyNewWindow;
// ...
}

MainWindow.cpp

// ...
   MainWindow::MainWindow()
   {
      // ...
      connect(mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
      // ...
   }
// ...
void MainWindow::openNewWindow()
{
   mMyNewWindow = new NewWindow(); // Be sure to destroy your window somewhere
   mMyNewWindow->show();
   // ...
}

This is an example on how display a custom new window. There are a lot of ways to do this.

Please see my answer here. As dreamwerx.myopenid.com points out, it is possible to do this with SimpleXML, but the DOM extension would be the better and more flexible way. Additionally there is a third way: using XMLWriter. It's much more simple to use than the DOM and therefore it's my preferred way of writing XML documents from scratch.

$w=new XMLWriter();
$w->openMemory();
$w->startDocument('1.0','UTF-8');
$w->startElement("root");
    $w->writeAttribute("ah", "OK");
    $w->text('Wow, it works!');
$w->endElement();
echo htmlentities($w->outputMemory(true));

By the way: DOM stands for Document Object Model; this is the standardized API into XML documents.

First of all, whether a class has methods or what it's class structure is has nothing to do with mutability.

ints and floats are immutable. If I do

a = 1
a += 5

It points the name a at a 1 somewhere in memory on the first line. On the second line, it looks up that 1, adds 5, gets 6, then points a at that 6 in memory -- it didn't change the 1 to a 6 in any way. The same logic applies to the following examples, using other immutable types:

b = 'some string'
b += 'some other string'
c = ('some', 'tuple')
c += ('some', 'other', 'tuple')

For mutable types, I can do thing that actallly change the value where it's stored in memory. With:

d = [1, 2, 3]

I've created a list of the locations of 1, 2, and 3 in memory. If I then do

e = d

I just point e to the same list d points at. I can then do:

e += [4, 5]

And the list that both e and d points at will be updated to also have the locations of 4 and 5 in memory.

If I go back to an immutable type and do that with a tuple:

f = (1, 2, 3)
g = f
g += (4, 5)

Then f still only points to the original tuple -- you've pointed g at an entirely new tuple.

Now, with your example of

class SortedKeyDict(dict):
    def __new__(cls, val):
        return dict.__new__(cls, val.clear())

Where you pass

d = (('zheng-cai', 67), ('hui-jun', 68),('xin-yi', 2))

(which is a tuple of tuples) as val, you're getting an error because tuples don't have a .clear() method -- you'd have to pass dict(d) as val for it to work, in which case you'll get an empty SortedKeyDict as a result.

Select first the text you want to format and then press Ctrl+I.

Use Cmd+A first if you wish to format all text in the selected file.

Note: this procedure only re-indents the lines, it does not do any advanced formatting.

In XCode 12 beta:

The new key binding to re-indent is control+I.

That Exception is thrown if there is already a key in the dictionary when you try to add the new one.

There must be more than one line in rct3Lines with the same first word. You can't have 2 entries in the same dictionary with the same key.

You need to decide what you want to happen if the key already exists - if you want to just update the value where the key exists you can simply

rct3Features[items[0]]=items[1]

but, if not you may want to test if the key already exists with:

if(rect3Features.ContainsKey(items[0]))
{
    //Do something
} 
else 
{
    //Do something else
}

The easiest way only if you don't need return something it'ts just return null

seperate your page from nav bar.

pageOne.php:

$page="one";
include("navigation.php");

navigation.php

if($page=="one"){$oneIsActive = 'class="active"';}else{ $oneIsActive=""; }
if($page=="two"){$twoIsActive = 'class="active"';}else{ $twoIsActive=""; }
if($page=="three"){$threeIsActive = 'class="active"';}else{ $threeIsActive=""; }

<ul class="nav">
  <li <?php echo $oneIsActive; ?>><a href="pageOne.php">One</a></li>
  <li <?php echo $twoIsActive; ?>><a href="pageTwo.php"><a href="#">Page 2</a></li>
  <li <?php echo $threeIsActive; ?>><a href="pageThree.php"><a href="#">Page 3</a></li>
</ul>

I found that I could also set the title of my pages with this method as well.

 $page="one";
 $title="This is page one."
 include("navigation.php");

and just grab the $title var and put it in between the "title" tags. Though I am sending it to my header page above my nav bar.

Solution for EF Core

public class User
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Passport { get; set; }
}

public class ApplicationContext : DbContext
{
    public DbSet<User> Users { get; set; }
    public ApplicationContext()
    {
        Database.EnsureCreated();
    }
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        optionsBuilder.UseSqlServer(@"Server=(localdb)\mssqllocaldb;Database=efbasicsappdb;Trusted_Connection=True;");
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<User>().HasAlternateKey(u => u.Passport);
        //or: modelBuilder.Entity<User>().HasAlternateKey(u => new { u.Passport, u.Name})
    }
}

DB table will look like this:

CREATE TABLE [dbo].[Users] (
    [Id]       INT            IDENTITY (1, 1) NOT NULL,
    [Name]     NVARCHAR (MAX) NULL,
    [Passport] NVARCHAR (450) NOT NULL,
    CONSTRAINT [PK_Users] PRIMARY KEY CLUSTERED ([Id] ASC),
    CONSTRAINT [AK_Users_Passport] UNIQUE NONCLUSTERED ([Passport] ASC)
);

My answer is based on the koma's but it doesn't require to override onStart but only onCreateView which is almost always overridden by default when you create new fragments.

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.your_fragment_layout, container);

    Rect displayRectangle = new Rect();
    Window window = getDialog().getWindow();
    window.getDecorView().getWindowVisibleDisplayFrame(displayRectangle);

    v.setMinimumWidth((int)(displayRectangle.width() * 0.9f));
    v.setMinimumHeight((int)(displayRectangle.height() * 0.9f));

    return v;
}

I've tested it on Android 5.0.1.

private boolean deleteFromExternalStorage(File file) {
                        String fileName = "/Music/";
                        String myPath= Environment.getExternalStorageDirectory().getAbsolutePath() + fileName;

                        file = new File(myPath);
                        System.out.println("fullPath - " + myPath);
                            if (file.exists() && file.canRead()) {
                                System.out.println(" Test - ");
                                file.delete();
                                return false; // File exists
                            }
                            System.out.println(" Test2 - ");
                            return true; // File not exists
                    }

I couldn't find an approach which suits me, so I propose my version. Of course, it needs input and error handling.

public void Rename(string filePath, string newFileName)
{
    var newFilePath = Path.Combine(Path.GetDirectoryName(filePath), newFileName + Path.GetExtension(filePath));
    System.IO.File.Move(filePath, newFilePath);
}

After experimenting for a few hours I figured it out.

<% if @user.errors.full_messages.any? %>
  <% @user.errors.full_messages.each do |error_message| %>
    <%= error_message if @user.errors.full_messages.first == error_message %> <br />
  <% end %>
<% end %>

Even better:

<%= @user.errors.full_messages.first if @user.errors.any? %>

Sure, for windows you can use:

$WshShell = new COM("WScript.Shell");
$oExec = $WshShell->Run("C:/path/to/php-win.exe -f C:/path/to/script.php", 0, false);

Note:

If you get a COM error, add the extension to your php.ini and restart apache:

[COM_DOT_NET]
extension=php_com_dotnet.dll

dirname(parent.frame(2)$ofile)  

doesn't work for me either, but the following (as suggested in https://stackoverflow.com/a/35842176/992088) works for me in ubuntu 14.04

dirname(rstudioapi::getActiveDocumentContext()$path)

I also recommend using Joda as mentioned before.

Solving your problem using standard Java Date objects only can be done as follows:

    // **** YOUR CODE **** BEGIN ****
    long ts = System.currentTimeMillis();
    Date localTime = new Date(ts);
    String format = "yyyy/MM/dd HH:mm:ss";
    SimpleDateFormat sdf = new SimpleDateFormat(format);

    // Convert Local Time to UTC (Works Fine)
    sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
    Date gmtTime = new Date(sdf.format(localTime));
    System.out.println("Local:" + localTime.toString() + "," + localTime.getTime() + " --> UTC time:"
            + gmtTime.toString() + "," + gmtTime.getTime());

    // **** YOUR CODE **** END ****

    // Convert UTC to Local Time
    Date fromGmt = new Date(gmtTime.getTime() + TimeZone.getDefault().getOffset(localTime.getTime()));
    System.out.println("UTC time:" + gmtTime.toString() + "," + gmtTime.getTime() + " --> Local:"
            + fromGmt.toString() + "-" + fromGmt.getTime());

Output:

Local:Tue Oct 15 12:19:40 CEST 2013,1381832380522 --> UTC time:Tue Oct 15 10:19:40 CEST 2013,1381825180000
UTC time:Tue Oct 15 10:19:40 CEST 2013,1381825180000 --> Local:Tue Oct 15 12:19:40 CEST 2013-1381832380000

Try the following code

Month = Date = DateTime.Now.Month.ToString();   
Year = DateTime.Now.Year.ToString(); 
ViewBag.Today = System.Globalization.CultureInfo.InvariantCulture.DateTimeFormat.GetMonthName(Int32.Parse(Month)) + Year;

Consider following:

    /// <summary>
    /// Returns max value
    /// </summary>
    /// <param name="arr">array to search in</param>
    /// <param name="index">index of the max value</param>
    /// <returns>max value</returns>
    public static int MaxAt(int[] arr, out int index)
    {
        index = -1;
        int max = Int32.MinValue;

        for (int i = 0; i < arr.Length; i++)
        {
            if (arr[i] > max)
            { 
                max = arr[i];
                index = i;
            }
        }

        return max;
    }

Usage:

int m, at;
m = MaxAt(new int[]{1,2,7,3,4,5,6}, out at);
Console.WriteLine("Max: {0}, found at: {1}", m, at);

A worked, completed and simple example:

package io.github.baijifeilong.excel;

import lombok.SneakyThrows;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

import java.io.FileOutputStream;

/**
 * Created by [email protected] at 2019/12/6 11:41
 */
public class ExcelBoldTextDemo {

    @SneakyThrows
    public static void main(String[] args) {

        new XSSFWorkbook() {{
            XSSFRow row = createSheet().createRow(0);
            row.setRowStyle(createCellStyle());
            row.getRowStyle().getFont().setBold(true);
            row.createCell(0).setCellValue("Alpha");
            row.createCell(1).setCellValue("Beta");
            row.createCell(2).setCellValue("Gamma");
        }}.write(new FileOutputStream("demo.xlsx"));
    }
}

This should work, but there is a little trick. After you enter the formula, you need to hold down Ctrl+Shift while you press Enter. When you do, you'll see that the formula bar has curly-braces around your formula. This is called an array formula.

For example, if the Months are in cells A2:A100 and the amounts are in cells B2:B100, your formula would look like {=SUM(If(A2:A100="January",B2:B100))}. You don't actually type the curly-braces though.

You could also do something like =SUM((A2:A100="January")*B2:B100). You'd still need to use the trick to get it to work correctly.

i think the problem is that there is no data in the success-function because the request breaks up with an 401 error in your case and thus has no success.

if you use

$.ajax({
        url: "https://app.asana.com/-/api/0.1/workspaces/",
        type: 'GET',
         error: function (xhr, ajaxOptions, thrownError) {
    alert(xhr.status);
    alert(thrownError);
  }
    });

there will be your 401 code i think (this link says so)

You can get back a commit after doing a reset --hard HEAD.

Make use of "git reflog" to check the history of the HEAD in the branch.

You will see your commit and its id here.

Do a

git reset {commit Id of the commit you want to bring back}

To me this worked.

CREATE USER 'spowner'@'localhost' IDENTIFIED BY '1234'; 
GRANT ALL PRIVILEGES ON test.* To 'spowner'@'localhost'; 
FLUSH PRIVILEGES;

where

• spowner : user name
• 1234 : password of spowner
• test : database 'spowner' has access right to

There are two "quick" methods:

x = length_of_your_list
a = [None]*x
# or
a = [None for _ in xrange(x)]

It appears that [None]*x is faster:

>>> from timeit import timeit
>>> timeit("[None]*100",number=10000)
0.023542165756225586
>>> timeit("[None for _ in xrange(100)]",number=10000)
0.07616496086120605

But if you are ok with a range (e.g. [0,1,2,3,...,x-1]), then range(x) might be fastest:

>>> timeit("range(100)",number=10000)
0.012513160705566406

Using loop in hbs little bit complex

<tbody>
     {{#each item}}
         <tr>
            <td><!--HOW TO GET ARRAY INDEX HERE?--></td>
            <td>{{@index}}</td>
            <td>{{this}}</td>
         </tr>
     {{/each}}
</tbody>

You can leverage Apache Commons StringUtils.isEmpty(str), which checks for empty strings and handles null gracefully.

Example:

System.out.println(StringUtils.isEmpty("")); // true
System.out.println(StringUtils.isEmpty(null)); // true

Google Guava also provides a similar, probably easier-to-read method: Strings.isNullOrEmpty(str).

Example:

System.out.println(Strings.isNullOrEmpty("")); // true
System.out.println(Strings.isNullOrEmpty(null)); // true

For really random strings, you can use

<?php

echo md5(microtime(true).mt_Rand());

outputs :

40a29479ec808ad4bcff288a48a25d5c

so even if you try to generate string multiple times at exact same time, you will get different output.

When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools

something like this:

   product.description = line[4]  
   product.price = '' #data is missing from file

I would create a jUnit inner class that inherits from the abstract class. This can be instantiated and have access to all the methods defined in the abstract class.

public class AbstractClassTest {

}


class ConcreteClass extends AbstractClass {

}

Inserts, updates, deletes and reads are generally OK from multiple threads, but Brad's answer is not correct. You have to be careful with how you create your connections and use them. There are situations where your update calls will fail, even if your database doesn't get corrupted.

The basic answer.

The SqliteOpenHelper object holds on to one database connection. It appears to offer you a read and write connection, but it really doesn't. Call the read-only, and you'll get the write database connection regardless.

So, one helper instance, one db connection. Even if you use it from multiple threads, one connection at a time. The SqliteDatabase object uses java locks to keep access serialized. So, if 100 threads have one db instance, calls to the actual on-disk database are serialized.

So, one helper, one db connection, which is serialized in java code. One thread, 1000 threads, if you use one helper instance shared between them, all of your db access code is serial. And life is good (ish).

If you try to write to the database from actual distinct connections at the same time, one will fail. It will not wait till the first is done and then write. It will simply not write your change. Worse, if you don’t call the right version of insert/update on the SQLiteDatabase, you won’t get an exception. You’ll just get a message in your LogCat, and that will be it.

So, multiple threads? Use one helper. Period. If you KNOW only one thread will be writing, you MAY be able to use multiple connections, and your reads will be faster, but buyer beware. I haven't tested that much.

Here's a blog post with far more detail and an example app.

Setting Map Container to position to relative do the trick. Here is HTML.

<body>
    <!-- Map container -->
    <div id="map_canvas"></div>
</body>

And Simple CSS.

<style>
html, body, #map_canvas {
    width: 100%;
    height: 100%;
    margin: 0;
    padding: 0;
}
#map_canvas {
    position: relative;
}
</style>

Tested on all browsers. Here is the Screenshot.

It sounds like the populate method is what your looking for. First make small change to your post schema:

var postSchema = new Schema({
    name: String,
    postedBy: {type: mongoose.Schema.Types.ObjectId, ref: 'User'},
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Then make your model:

var Post = mongoose.model('Post', postSchema);

Then, when you make your query, you can populate references like this:

Post.findOne({_id: 123})
.populate('postedBy')
.exec(function(err, post) {
    // do stuff with post
});

Try,

var newList = 
(
from x in empCollection
select new {Loc = x.empLoc, PL = x.empPL, Shift = x.empShift}
).Distinct();

In case you have a loop with an async request in each one and you want a certain time between each request you can use this code:

   var startTimeout = function(timeout, i){
        setTimeout(function() {
            myAsyncFunc(i).then(function(data){
                console.log(data);
            })
        }, timeout);
   }

   var myFunc = function(){
        timeout = 0;
        i = 0;
        while(i < 10){
            // By calling a function, the i-value is going to be 1.. 10 and not always 10
            startTimeout(timeout, i);
            // Increase timeout by 1 sec after each call
            timeout += 1000;
            i++;
        }
    }

This examples waits 1 second after each request before sending the next one.

If you want to do this without VBA, you can use a combination of IF, ISERROR, and MATCH.

So if all values are in column A, enter this formula in column B:

=IF(ISERROR(MATCH(12345,A:A,0)),"Not Found","Value found on row " & MATCH(12345,A:A,0))

This will look for the value "12345" (which can also be a cell reference). If the value isn't found, MATCH returns "#N/A" and ISERROR tries to catch that.

If you want to use VBA, the quickest way is to use a FOR loop:

Sub FindMatchingValue()
    Dim i as Integer, intValueToFind as integer
    intValueToFind = 12345
    For i = 1 to 500    ' Revise the 500 to include all of your values
        If Cells(i,1).Value = intValueToFind then 
            MsgBox("Found value on row " & i)
            Exit Sub
        End If
    Next i

    ' This MsgBox will only show if the loop completes with no success
    MsgBox("Value not found in the range!")  
End Sub

You can use Worksheet Functions in VBA, but they're picky and sometimes throw nonsensical errors. The FOR loop is pretty foolproof.

go to http://dev.mysql.com/downloads/connector/c/ and download MySQL Connector/C. after getting the package, make a new directory 'mysql', uncompress the Mysql Connector file under directory mysql, then under mysql, make another empty directory 'build'.we will use 'build' to build MySQL Connector/C. cd build && cmake ../your-MySQL-Connector-source-dir make && make install after make install, you will get a directory named mysql under /usr/local. it contains all the headers and libs you need.go to this dirctory, and copy the headers and libs to corresponding locations.

I found this question because I wanted to generate a web page with links to all the websites running on my IIS instance. I used Alexander Shapkin's answer to come up with the following to generate a bunch of links.

$hostname = "localhost"

Foreach ($Site in get-website) {
    Foreach ($Bind in $Site.bindings.collection) {
        $data = [PSCustomObject]@{
            name=$Site.name;
            Protocol=$Bind.Protocol;
            Bindings=$Bind.BindingInformation
        }
        $data.Bindings = $data.Bindings -replace '(:$)', ''
        $html = "<a href=""" + $data.Protocol + "://" + $data.Bindings + """>" + $data.name + "</a>"
        $html.Replace("*", $hostname);
    }
}

Then I paste the results into this hastily written HTML:

<html>
<style>
    a { display: block; }
</style>
{paste PowerShell results here}
</body>
</html>

    ArrayTest obj=new ArrayTest(1);

    test.add(obj1);
    ArrayTest obj2=new ArrayTest(3);
    test.add(obj2);

    test.remove(object of ArrayTest);

you can specify how you control each object.

I've noticed that if you set the theme in the AndroidManifest, it seems to get rid of that short time where you can see the action bar. So, try adding this to your manifest:

<android:theme="@android:style/Theme.NoTitleBar">

Just add it to your application tag to apply it app-wide.

In this case the file which you want to get is stored in the strpath variable:

string strPath = Server.MapPath(Request.ApplicationPath) + "/contents/member/" + strFileName;

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

You can achieve this using the location object.

location.href = "http://someurl"; 

The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.

So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use

HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...

HttpEntity entity = new HttpEntity(headers);

ResponseEntity<String> response = restTemplate.exchange(
    url, HttpMethod.GET, entity, String.class, param);

Finally, use response.getBody() to get your result.

This question is similar to this question.

This is because you are adding your <tbody> tag before <td> in table you cannot print any data without <td>.

So for that you have to make a <div> say #header with position: fixed;

 header
 {
      position: fixed;
 }

make another <div> which will act as <tbody>

tbody
{
    overflow:scroll;
}

Now your header is fixed and the body will scroll. And the header will remain there.

We ended up realising that our one server that was experiencing this had busted fpm config resulting in php errors/warnings/notices that'd normally be logged to disk were being sent over the FCGI socket. It looks like there's a parsing bug when part of the header gets split across the buffer chunks.

So setting php_admin_value[error_log] to something actually writeable and restarting php-fpm was enough to fix the problem.

We could reproduce the problem with a smaller script:

<?php
for ($i = 0; $i<$_GET['iterations']; $i++)
    error_log(str_pad("a", $_GET['size'], "a"));
echo "got here\n";

Raising the buffers made the 502s harder to hit but not impossible, e.g native:

bash-4.1# for it in {30..200..3}; do for size in {100..250..3}; do echo "size=$size iterations=$it $(curl -sv "http://localhost/debug.php?size=$size&iterations=$it" 2>&1 | egrep '^< HTTP')"; done; done | grep 502 | head
size=121 iterations=30 < HTTP/1.1 502 Bad Gateway
size=109 iterations=33 < HTTP/1.1 502 Bad Gateway

So I believe the correct answer is: fix your fpm config so it logs errors to disk.

You can't. The emulator does not support Bluetooth, as mentioned in the SDK's docs and several other places. Android emulator does not have bluetooth capabilities".

You can only use real devices.

Emulator Limitations

The functional limitations of the emulator include:

• No support for placing or receiving actual phone calls. However, You can simulate phone calls (placed and received) through the emulator console
• No support for USB
• No support for device-attached headphones
• No support for determining SD card insert/eject
• No support for WiFi, Bluetooth, NFC

Refer to the documentation

If you are "getting data" from an application, the sensible thing would be to use the profiler and profile the database while running the application. Trace it, then search the results for that string.

simple query would be, just set a variable to some number you want. then update the column you need by incrementing 1 from that number. for all the rows it'll update each row id by incrementing 1

SET @a  = 50000835 ;  
UPDATE `civicrm_contact` SET external_identifier = @a:=@a+1 
WHERE external_identifier IS NULL;

As checking for members of a collection is a general problem, here is an abstracted version of Tim's answer:

Function Contains(objCollection As Object, strName as String) As Boolean
    Dim o as Object
    On Error Resume Next
    set o = objCollection(strName)
    Contains = (Err.Number = 0)
    Err.Clear
 End Function

This function can be used with any collection like object (Shapes, Range, Names, Workbooks, etc.).

To check for the existence of a sheet, use If Contains(Sheets, "SheetName") ...

The len() function can be used with several different types in Python - both built-in types and library types. For example:

>>> len([1, 2, 3])
3

When you are checking if an element has or does not have a class, make sure you didn't accidentally put a dot in the class name:

<div class="className"></div>

$('div').hasClass('className');
$('div').hasClass('.className'); #will not work!!!!

After a long time of staring at my code I realized I had done this. A little typo like this took me an hour to figure out what I had done wrong. Check your code!

Twitter bootstrap tables can be styled and well designed. You can style your table just adding some classes on your table and it’ll look nice. You might use it on your data reports, showing information, etc.

You can use :

basic table
Striped rows
Bordered table
Hover rows
Condensed table
Contextual classes
Responsive tables

Striped rows Table :

    <table class="table table-striped" width="647">
    <thead>
    <tr>
    <th>#</th>
    <th>Name</th>
    <th>Address</th>
    <th>mail</th>
    </tr>
    </thead>
    <tbody>
    <tr>
    <td>1</td>
    <td>Thomas bell</td>
    <td>Brick lane, London</td>
    <td>[email protected]</td>
    </tr>
    <tr>
    <td height="29">2</td>
    <td>Yan Chapel</td>
    <td>Toronto Australia</td>
    <td>[email protected]</td>
    </tr>
    <tr>
    <td>3</td>
    <td>Pit Sampras</td>
    <td>Berlin, Germany</td>
    <td>Pit @yahoo.com</td>
    </tr>
    </tbody>
    </table>

Condensed table :

Compacting a table you need to add class class=”table table-condensed” .

    <table class="table table-condensed" width="647">
    <thead>
    <tr>
    <th>#</th>
    <th>Sample Name</th>
    <th>Address</th>
    <th>Mail</th>
    </tr>
    </thead>
    <tbody>
    <tr>
    <td>1</td>
    <td>Thomas bell</td>
    <td>Brick lane, London</td>
    <td>[email protected]</td>
    </tr>
    <tr>
    <td height="29">2</td>
    <td>Yan Chapel</td>
    <td>Toronto Australia</td>
    <td>[email protected]</td>
    </tr>
    <tr>
    <td>3</td>
    <td>Pit Sampras</td>
    <td>Berlin, Germany</td>
    <td>Pit @yahoo.com</td>
    </tr>
    <tr>
    <td></td>
    <td colspan="3" align="center"></td>
    </tr>
    </tbody>
    </table>

Like others mentioned you cannot delete current branch in which you are working.

In my case, I have selected "Test_Branch" in Visual Studio and was trying to delete "Test_Branch" from Sourcetree (Git GUI). And was getting below error message.

Cannot delete branch 'Test_Branch' checked out at '[directory location]'.

Switched to different branch in Visual Studio and was able to delete "Test_Branch" from Sourcetree.

I hope this helps someone who is using Visual Studio & Sourcetree.

You can also dynamically create a class by using DynamicExpressions.

Since 'Dictionary's have compact initializers and handle key collisions, you will want to do something like this.

  var list = new Dictionary<string, string> {
    {
      "EmployeeID",
      "int"
    }, {
      "EmployeeName",
      "String"
    }, {
      "Birthday",
      "DateTime"
    }
  };

Or you might want to use a JSON converter to construct your serialized string object into something manageable.

Then using System.Linq.Dynamic;

  IEnumerable<DynamicProperty> props = list.Select(property => new DynamicProperty(property.Key, Type.GetType(property.Value))).ToList();

  Type t = DynamicExpression.CreateClass(props);

The rest is just using System.Reflection.

  object obj = Activator.CreateInstance(t);
  t.GetProperty("EmployeeID").SetValue(obj, 34, null);
  t.GetProperty("EmployeeName").SetValue(obj, "Albert", null);
  t.GetProperty("Birthday").SetValue(obj, new DateTime(1976, 3, 14), null);
}  

If you're wondering how to get the file content from each ZipEntry it's actually quite simple. Here's a sample code:

public static void main(String[] args) throws IOException {
    ZipFile zipFile = new ZipFile("C:/test.zip");

    Enumeration<? extends ZipEntry> entries = zipFile.entries();

    while(entries.hasMoreElements()){
        ZipEntry entry = entries.nextElement();
        InputStream stream = zipFile.getInputStream(entry);
    }
}

Once you have the InputStream you can read it however you want.

It's a horribly obscure way to do a type conversion.

! is NOT. So !true is false, and !false is true. !0 is true, and !1 is false.

So you're converting a value to a boolean, then inverting it, then inverting it again.

// Maximum Obscurity:
val.enabled = !!userId;

// Partial Obscurity:
val.enabled = (userId != 0) ? true : false;

// And finally, much easier to understand:
val.enabled = (userId != 0);

To change both the author date and the commit date:

GIT_COMMITTER_DATE="Wed Sep 23 9:40 2015 +0200" git commit --amend --date "Wed Sep 23 9:40 2015 +0200"

I have modified the solution of @yogi. The addition is that when the file is of incorrect format I reset the input element value.

function checkFile(sender, validExts) {
    var fileExt = sender.value;
    fileExt = fileExt.substring(fileExt.lastIndexOf('.'));
    if (validExts.indexOf(fileExt) < 0 && fileExt != "") {
        alert("Invalid file selected, valid files are of " +
                 validExts.toString() + " types.");
        $(sender).val("");
        return false;
    }
    else return true;
}

I have custom verification buildin, because in open file window the user can still choose the options "All files ('*')", regardless if I explicitly set the accept attribute in input element.

Don't forget: to get HTTPS contents, your OPENSSL extension should be enabled in your php.ini. (how to get contents of site use HTTPS)

I have your answer, as I just had the same problem today:

Someone made a working vba code that changes the vba protection password to "macro", for all excel files, including .xlsm (2007+ versions). You can see how it works by browsing his code.

This is the guy's blog: http://lbeliarl.blogspot.com/2014/03/excel-removing-password-from-vba.html Here's the file that does the work: https://docs.google.com/file/d/0B6sFi5sSqEKbLUIwUTVhY3lWZE0/edit

Pasted from a previous post from his blog:

For Excel 2007/2010 (.xlsm) files do following steps:

1. Create a new .xlsm file.
2. In the VBA part, set a simple password (for instance 'macro').
3. Save the file and exit.
4. Change file extention to '.zip', open it by any archiver program.
5. Find the file: 'vbaProject.bin' (in 'xl' folder).
6. Extract it from archive.
7. Open the file you just extracted with a hex editor.

8. Find and copy the value from parameter DPB (value in quotation mark), example: DPB="282A84CBA1CBA1345FCCB154E20721DE77F7D2378D0EAC90427A22021A46E9CE6F17188A". (This value generated for 'macro' password. You can use this DPB value to skip steps 1-8)

9. Do steps 4-7 for file with unknown password (file you want to unlock).

10. Change DBP value in this file on value that you have copied in step 8.

    If copied value is shorter than in encrypted file you should populate missing characters with 0 (zero). If value is longer - that is not a problem (paste it as is).

11. Save the 'vbaProject.bin' file and exit from hex editor.

12. Replace existing 'vbaProject.bin' file with modified one.
13. Change extention from '.zip' back to '.xlsm'
14. Now, open the excel file you need to see the VBA code in. The password for the VBA code will simply be macro (as in the example I'm showing here).

I used this approach in a recent project and I was pretty happy with the result:

.select-wrapper {
    position: relative;
    &::after {
        position: absolute;
        top: 0;
        right: 0;
        width: 100px;
        height: 100%;
        content: "";
        background: linear-gradient(to right, transparent, white);
        pointer-events: none;
    }
}

Basically, wrap the select in a div and insert a pseudo element to overlay the end of the text to create the appearance that the text fades out.

If you are using downloading data using url...may need to use

var result = client.DownloadData(url);

There are multiple ways of doing that you can use either place or grid or even the packmethod.

Sample code:

from tkinter import *
root = Tk()

l = Label(root, text="hello" )
l.pack(padx=6, pady=4) # where padx and pady represent the x and y axis respectively
# well you can also use side=LEFT inside the pack method of the label widget.

To place a widget to on basis of columns and rows , use the grid method:

but = Button(root, text="hello" )
but.grid(row=0, column=1)

I had a similar error which caused json_encode to return a null field whenever there was a hi-ascii character such as a curly apostrophe in a string, due to the wrong character set being returned in the query.

The solution was to make sure it comes as utf8 by adding:

mysql_set_charset('utf8');

after the mysql connect statement.

Do you mean like this?

import string
astr='a(b[c])d'

deleter=string.maketrans('()[]','    ')
print(astr.translate(deleter))
# a b c  d
print(astr.translate(deleter).split())
# ['a', 'b', 'c', 'd']
print(list(reversed(astr.translate(deleter).split())))
# ['d', 'c', 'b', 'a']
print(' '.join(reversed(astr.translate(deleter).split())))
# d c b a

This is my answer,

1, 2, 3 ,... are invalid identifiers in python because first of all they are integer objects and secondly in python a variable name can't start with a number.

>>> 1 = 12    #you can't assign to an integer
  File "<ipython-input-177-30a62b7248f1>", line 1
SyntaxError: can't assign to literal

>>> 1a = 12   #1a is an invalid variable name
  File "<ipython-input-176-f818ca46b7dc>", line 1
    1a = 12
     ^
SyntaxError: invalid syntax

Valid identifier definition:

identifier ::=  (letter|"_") (letter | digit | "_")*
letter     ::=  lowercase | uppercase
lowercase  ::=  "a"..."z"
uppercase  ::=  "A"..."Z"
digit      ::=  "0"..."9"

The problem is with your notificationId. Think it as an array index. Each time you update your notification, the notificationId is the place it takes to store value. As you are not incrementing your int value (in this case, your notificationId), this always replaces the previous one. The best solution I guess is to increment it just after you update a notification. And if you want to keep it persistent, then you can store the value of your notificationId in sharedPreferences. Whenever you come back, you can just grab the last integer value (notificationId stored in sharedPreferences) and use it.

SELECT CONVERT(date, GETDATE())

1. Extend "LinearLayout" class and override the necessary functions
2. Create an instance of the above class in your fragment or activity
3. Call "recyclerView.smoothScrollToPosition(targetPosition)

CustomLinearLayout.kt :

class CustomLayoutManager(private val context: Context, layoutDirection: Int):
  LinearLayoutManager(context, layoutDirection, false) {

    companion object {
      // This determines how smooth the scrolling will be
      private
      const val MILLISECONDS_PER_INCH = 300f
    }

    override fun smoothScrollToPosition(recyclerView: RecyclerView, state: RecyclerView.State, position: Int) {

      val smoothScroller: LinearSmoothScroller = object: LinearSmoothScroller(context) {

        fun dp2px(dpValue: Float): Int {
          val scale = context.resources.displayMetrics.density
          return (dpValue * scale + 0.5f).toInt()
        }

        // change this and the return super type to "calculateDyToMakeVisible" if the layout direction is set to VERTICAL
        override fun calculateDxToMakeVisible(view: View ? , snapPreference : Int): Int {
          return super.calculateDxToMakeVisible(view, SNAP_TO_END) - dp2px(50f)
        }

        //This controls the direction in which smoothScroll looks for your view
        override fun computeScrollVectorForPosition(targetPosition: Int): PointF ? {
          return this @CustomLayoutManager.computeScrollVectorForPosition(targetPosition)
        }

        //This returns the milliseconds it takes to scroll one pixel.
        override fun calculateSpeedPerPixel(displayMetrics: DisplayMetrics): Float {
          return MILLISECONDS_PER_INCH / displayMetrics.densityDpi
        }
      }
      smoothScroller.targetPosition = position
      startSmoothScroll(smoothScroller)
    }
  }

Note: The above example is set to HORIZONTAL direction, you can pass VERTICAL/HORIZONTAL during initialization.

If you set the direction to VERTICAL you should change the "calculateDxToMakeVisible" to "calculateDyToMakeVisible" (also mind the supertype call return value)

Activity/Fragment.kt :

...
smoothScrollerLayoutManager = CustomLayoutManager(context, LinearLayoutManager.HORIZONTAL)
recyclerView.layoutManager = smoothScrollerLayoutManager
.
.
.
fun onClick() {
  // targetPosition passed from the adapter to activity/fragment
  recyclerView.smoothScrollToPosition(targetPosition)
}

The tibble package now has a dedicated function that converts row names to an explicit variable.

Send SMS/Text Messages from Command Line with VBScript!

If VBA meets the rules for VB Script then it can be called from command line by simply placing it into a text file - in this case there's no need to specifically open Outlook.

I had a need to send automated text messages to myself from the command line, so I used the code below, which is just a compressed version of @Geoff's answer above.

Most mobile phone carriers worldwide provide an email address "version" of your mobile phone number. For example in Canada with Rogers or Chatr Wireless, an email sent to <YourPhoneNumber> @pcs.rogers.com will be immediately delivered to your Rogers/Chatr phone as a text message.

* ^{You may need to "authorize" the first message on your phone, and some carriers may charge an additional fee for theses message although as far as I know, all Canadian carriers provide this little-known service for free. Check your carrier's website for details.}

There are further instructions and various compiled lists of worldwide carrier's Email-to-Text addresses available online such as this and this and this.

Code & Instructions

1. Copy the code below and paste into a new file in your favorite text editor.
2. Save the file with any name with a .VBS extension, such as TextMyself.vbs.

That's all!
Just double-click the file to send a test message, or else run it from a batch file using START.

Sub SendMessage()
    Const EmailToSMSAddy = "[email protected]"
    Dim objOutlookRecip
    With CreateObject("Outlook.Application").CreateItem(0)
        Set objOutlookRecip = .Recipients.Add(EmailToSMSAddy)
        objOutlookRecip.Type = 1
        .Subject = "The computer needs your attention!"
        .Body = "Go see why Windows Command Line is texting you!"
        .Save
        .Send
    End With
End Sub

Example Batch File Usage:

START x:\mypath\TextMyself.vbs

Of course there are endless possible ways this could be adapted and customized to suit various practical or creative needs.

Alternative syntax using the -Not operator and depending on your preference for readability:

if( -Not (Test-Path -Path $TARGETDIR ) )
{
    New-Item -ItemType directory -Path $TARGETDIR
}

TextView view = (TextView) findViewById(R.id.textView);
view.setText("Add your text here");
view.setVisibility(View.VISIBLE);

for (Object key : meMap.keySet()) {
        String value=(String)meMap.get(key);
        Toast.makeText(ctx, "Key: "+key+" Value: "+value, Toast.LENGTH_LONG).show();
    }

This is what I would do:

#include <cmath>

int roundUp(int numToRound, int multiple)
{
    // if our number is zero, return immediately
   if (numToRound == 0)
        return multiple;

    // if multiplier is zero, return immediately
    if (multiple == 0)
        return numToRound;

    // how many times are number greater than multiple
    float rounds = static_cast<float>(numToRound) / static_cast<float>(multiple);

    // determine, whether if number is multiplier of multiple
    int floorRounds = static_cast<int>(floor(rounds));

    if (rounds - floorRounds > 0)
        // multiple is not multiplier of number -> advance to the next multiplier
        return (floorRounds+1) * multiple;
    else
        // multiple is multiplier of number -> return actual multiplier
        return (floorRounds) * multiple;
}

The code might not be optimal, but I prefer clean code than dry performance.

this error happened with me when i am using interceptor you have to do this in your interceptor

return next.handle(request).map(event => {
        if (event instanceof HttpResponse) {

        }
        return event;
    },
      catchError((error: HttpErrorResponse) => {
        if (error.status === 401 || error.status === 400) {
          // some logic

        }

signal isn't the most reliable way as it differs in implementations. I would recommend using sigaction. Tom's code would now look like this :

#include <signal.h>
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>

void my_handler(int s){
           printf("Caught signal %d\n",s);
           exit(1); 

}

int main(int argc,char** argv)
{

   struct sigaction sigIntHandler;

   sigIntHandler.sa_handler = my_handler;
   sigemptyset(&sigIntHandler.sa_mask);
   sigIntHandler.sa_flags = 0;

   sigaction(SIGINT, &sigIntHandler, NULL);

   pause();

   return 0;    
}

To my knowledge there is no cross-browser compatible way to make a circle with CSS & HTML only.

For the square I guess you could make a div with a border and a z-index higher than what you are putting it over. I don't understand why you would need to do this, when you could just put a border on the image or "something" itself.

If anyone else knows how to make a circle that is cross browser compatible with CSS & HTML only, I would love to hear about it!

@Caspar Kleijne border-radius does not work in IE8 or below, not sure about 9.

I think the $() syntax is easier to read...

variable=$(ps -ef | grep "port 10 -" | grep -v "grep port 10 -"| awk '{printf "%s", $12}')

But the real issue is probably that $12 should not be qouted with ""

Edited since the question was changed, This returns valid data, but it is not clear what the expected output of ps -ef is and what is expected in variable.

$("span").mouseover(function () {
$(this).css({"background-color":"green","font-size":"20px","color":"red"});
});

Ok, solved :) Angular UI Router has this new method, $urlRouterProvider.deferIntercept() https://github.com/angular-ui/ui-router/issues/64

basically it comes down to this:

angular.module('myApp', [ui.router])
  .config(['$urlRouterProvider', function ($urlRouterProvider) {
    $urlRouterProvider.deferIntercept();
  }])
  // then define the interception
  .run(['$rootScope', '$urlRouter', '$location', '$state', function ($rootScope, $urlRouter, $location, $state) {
    $rootScope.$on('$locationChangeSuccess', function(e, newUrl, oldUrl) {
      // Prevent $urlRouter's default handler from firing
      e.preventDefault();

      /** 
       * provide conditions on when to 
       * sync change in $location.path() with state reload.
       * I use $location and $state as examples, but
       * You can do any logic
       * before syncing OR stop syncing all together.
       */

      if ($state.current.name !== 'main.exampleState' || newUrl === 'http://some.url' || oldUrl !=='https://another.url') {
        // your stuff
        $urlRouter.sync();
      } else {
        // don't sync
      }
    });
    // Configures $urlRouter's listener *after* your custom listener
    $urlRouter.listen();
  }]);

I think this method is currently only included in the master version of angular ui router, the one with optional parameters (which are nice too, btw). It needs to be cloned and built from source with

grunt build

The docs are accessible from the source as well, through

grunt ngdocs

(they get built into the /site directory) // more info in README.MD

There seems to be another way to do this, by dynamic parameters (which I haven't used). Many credits to nateabele.

As a sidenote, here are optional parameters in Angular UI Router's $stateProvider, which I used in combination with the above:

angular.module('myApp').config(['$stateProvider', function ($stateProvider) {    

  $stateProvider
    .state('main.doorsList', {
      url: 'doors',
      controller: DoorsListCtrl,
      resolve: DoorsListCtrl.resolve,
      templateUrl: '/modules/doors/doors-list.html'
    })
    .state('main.doorsSingle', {
      url: 'doors/:doorsSingle/:doorsDetail',
      params: {
        // as of today, it was unclear how to define a required parameter (more below)
        doorsSingle: {value: null},
        doorsDetail: {value: null}
      },
      controller: DoorsSingleCtrl,
      resolve: DoorsSingleCtrl.resolve,
      templateUrl: '/modules/doors/doors-single.html'
    });

}]);

what that does is it allows to resolve a state, even if one of the params is missing. SEO is one purpose, readability another.

In the example above, I wanted doorsSingle to be a required parameter. It is not clear how to define those. It works ok with multiple optional parameters though, so not really a problem. The discussion is here https://github.com/angular-ui/ui-router/pull/1032#issuecomment-49196090

You need to use a graphics library. Put this in your preamble:

\usepackage{graphicx}

You can then add images like this:

\begin{figure}[ht!]
\centering
\includegraphics[width=90mm]{fixed_dome1.jpg}
\caption{A simple caption \label{overflow}}
\end{figure}

This is the basic template I use in my documents. The position and size should be tweaked for your needs. Refer to the guide below for more information on what parameters to use in \figure and \includegraphics. You can then refer to the image in your text using the label you gave in the figure:

And here we see figure \ref{overflow}.

Read this guide here for a more detailed instruction: http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions

Java 8

import java.util.Arrays;
import java.util.List;
import java.util.ArrayList;

public class HelloWorld{

     public static void main(String []args){
            List<List<String>> stringListList = new ArrayList<>();
            stringListList.add(Arrays.asList(new String[] {"(0,0)", "(0,1)"} ));
            stringListList.add(Arrays.asList(new String[] {"(1,0)", "(1,1)", "(1,2)"} ));
            stringListList.add(Arrays.asList(new String[] {"(2,0)", "(2,1)"} ));

            int count=stringListList.stream().mapToInt(i -> i.size()).sum();

            System.out.println("stringListList count: "+count);
     }
}

The isConnected method won't help, it will return true even if the remote side has closed the socket. Try this:

public class MyServer {
    public static final int PORT = 12345;
    public static void main(String[] args) throws IOException, InterruptedException {
        ServerSocket ss = ServerSocketFactory.getDefault().createServerSocket(PORT);
        Socket s = ss.accept();
        Thread.sleep(5000);
        ss.close();
        s.close();
    }
}

public class MyClient {
    public static void main(String[] args) throws IOException, InterruptedException {
        Socket s = SocketFactory.getDefault().createSocket("localhost", MyServer.PORT);
        System.out.println(" connected: " + s.isConnected());
        Thread.sleep(10000);
        System.out.println(" connected: " + s.isConnected());
    }
}

Start the server, start the client. You'll see that it prints "connected: true" twice, even though the socket is closed the second time.

The only way to really find out is by reading (you'll get -1 as return value) or writing (an IOException (broken pipe) will be thrown) on the associated Input/OutputStreams.

I had to remove my branch from my command line at:

.git\refs\remotes\{my remote}\{**my branch**}

and then manually doing:

git pull [remote_name] [branch_name]

I was able to pull the changes.

Note: I was using SourceTree and was unable to do the pull.

As long as you specify a width on the element, it should wrap itself without needing anything else.

You could select and style this with JavaScript or jQuery, but CSS alone can't do this.

For example, if you have jQuery implemented on the site, you could just do:

var last_visible_element = $('div:visible:last');

Although hopefully you'll have a class/ID wrapped around the divs you're selecting, in which case your code would look like:

var last_visible_element = $('#some-wrapper div:visible:last');

After wrestling with this problem today my opinion is this: BEGIN...END brackets code just like {....} does in C languages, e.g. code blocks for if...else and loops

GO is (must be) used when succeeding statements rely on an object defined by a previous statement. USE database is a good example above, but the following will also bite you:

alter table foo add bar varchar(8);
-- if you don't put GO here then the following line will error as it doesn't know what bar is.
update foo set bar = 'bacon';
-- need a GO here to tell the interpreter to execute this statement, otherwise the Parser will lump it together with all successive statements.

It seems to me the problem is this: the SQL Server SQL Parser, unlike the Oracle one, is unable to realise that you're defining a new symbol on the first line and that it's ok to reference in the following lines. It doesn't "see" the symbol until it encounters a GO token which tells it to execute the preceding SQL since the last GO, at which point the symbol is applied to the database and becomes visible to the parser.

Why it doesn't just treat the semi-colon as a semantic break and apply statements individually I don't know and wish it would. Only bonus I can see is that you can put a print() statement just before the GO and if any of the statements fail the print won't execute. Lot of trouble for a minor gain though.

I wanted to delete all records from both tables because it was all test data. I used SSMS GUI to temporarily disable a FK constraint, then I ran a DELETE query on both tables, and finally I re-enabled the FK constraint.

To disable the FK constraint:

1. expand the database object [1]
2. expand the dependant table object [2]
3. expand the 'Keys' folder
4. right click on the foreign key
5. choose the 'Modify' option
6. change the 'Enforce Foreign Key Constraint' option to 'No'
7. close the 'Foreign Key Relationships' window
8. close the table designer tab
9. when prompted confirm save changes
10. run necessary delete queries
11. re-enable foreign key constraint the same way you just disabled it.

[1] in the 'Object Explorer' pane, can be accessed via the 'View' menu option, or key F8

[2] if you're not sure which table is the dependant one, you can check by right clicking the table in question and selecting the 'View Dependencies' option.

I agree with Cat Plus Plus's answer. However, if you know this will only be used on Unix-like OSes, you can use external calls to the shell commands mkdir, chmod, and chown. Make sure to pass extra flags to recursively affect directories:

>>> import subprocess
>>> subprocess.check_output(['mkdir', '-p', 'first/second/third']) 
# Equivalent to running 'mkdir -p first/second/third' in a shell (which creates
# parent directories if they do not yet exist).

>>> subprocess.check_output(['chown', '-R', 'dail:users', 'first'])
# Recursively change owner to 'dail' and group to 'users' for 'first' and all of
# its subdirectories.

>>> subprocess.check_output(['chmod', '-R', 'g+w', 'first'])
# Add group write permissions to 'first' and all of its subdirectories.

EDIT I originally used commands, which was a bad choice since it is deprecated and vulnerable to injection attacks. (For example, if a user gave input to create a directory called first/;rm -rf --no-preserve-root /;, one could potentially delete all directories).

EDIT 2 If you are using Python less than 2.7, use check_call instead of check_output. See the subprocess documentation for details.

Map is a part of the enumerable module. Very similar to "collect" For Example:

  Class Car

    attr_accessor :name, :model, :year

    Def initialize (make, model, year)
      @make, @model, @year = make, model, year
    end

  end

  list = []
  list << Car.new("Honda", "Accord", 2016)
  list << Car.new("Toyota", "Camry", 2015)
  list << Car.new("Nissan", "Altima", 2014)

  p list.map {|p| p.model}

Map provides values iterating through an array that are returned by the block parameters.

Just to correct mingos' answer:

If you set the expiration time to 0, the cookie won't be created at all. I've tested this on Google Chrome at least, and when set to 0 that was the result. The cookie, I guess, expires immediately after creation.

To set a cookie so it expires at the end of the browsing session, simply OMIT the expiration parameter altogether.

Example:

Instead of:

document.cookie = "cookie_name=cookie_value; 0; path=/";

Just write:

document.cookie = "cookie_name=cookie_value; path=/";

Double quotes not worked for me, it worked for me \". If you want to place a double quotes as example you can set \"\".

You can build formulas, as example:

fprintf(strout, "\"=if(C3=1,\"\"\"\",B3)\"\n");

will write in csv:

=IF(C3=1,"",B3)

JSON.stringify and JSON.parse are almost oposites, and "usually" this kind of thing will work:

var obj = ...;
var json = JSON.stringify(obj);  
var obj2 = JSON.parse(json);

so that obj and obj2 are "the same".

However there are some limitations to be aware of. Often these issues dont matter as you're dealing with simple objects. But I'll illustrate some of them here, using this helper function:

function jsonrepack( obj ) { return JSON.parse(JSON.stringify(obj) ); }

• You'll only get ownProperties of the object and lose prototypes:

  var MyClass = function() { this.foo="foo"; } 
  MyClass.prototype = { bar:"bar" }
  
  var o = new MyClass();
  var oo = jsonrepack(o);
  console.log(oo.bar); // undefined
  console.log( oo instanceof MyClass ); // false
  

• You'll lose identity:

  var o = {};
  var oo = jsonrepack(o);
  console.log( o === oo ); // false
  

• Functions dont survive:

  jsonrepack( { f:function(){} } ); // Returns {}
  

• Date objects end up as strings:

  jsonrepack(new Date(1990,2,1)); // Returns '1990-02-01T16:00:00.000Z'
  

• Undefined values dont survive:

  var v = { x:undefined }
  console.log("x" in v);              // true
  console.log("x" in jsonrepack(v));  // false
  

• Objects that provide a toJSON function may not behave correctly.

  x = { f:"foo", toJSON:function(){ return "EGAD"; } }
  jsonrepack(x) // Returns 'EGAD'
  

I'm sure there are issues with other built-in-types too. (All this was tested using node.js so you may get slightly different behaviour depending on your environment too).

When it does matter it can sometimes be overcome using the additional parameters of JSON.parse and JSON.stringify. For example:

function MyClass (v) {
   this.date = new Date(v.year,1,1);
   this.name = "an object";
};

MyClass.prototype.dance = function() {console.log("I'm dancing"); }

var o = new MyClass({year:2010});
var s = JSON.stringify(o);

// Smart unpack function
var o2 = JSON.parse( s, function(k,v){
  if(k==="") { 
     var rv = new MyClass(1990,0,0);
     rv.date = v.date;
     rv.name = v.name;
     return rv
  } else if(k==="date") {
    return new Date( Date.parse(v) );
  } else { return v; } } );

console.log(o);             // { date: <Mon Feb 01 2010 ...>, name: 'an object' }
console.log(o.constructor); // [Function: MyClass]
o.dance();                  // I'm dancing

console.log(o2);            // { date: <Mon Feb 01 2010 ...>, name: 'an object' }
console.log(o2.constructor) // [Function: MyClass]        
o2.dance();                 // I'm dancing

Try using xmltype.createxml(xml).

As in,

select extract(xmltype.createxml(xml), '//fax').getStringVal() from mytab;

It worked for me.

If you want to improve or manipulate even further.

Try something like this.

Select *
from xmltable(xmlnamespaces('some-name-space' as "ns", 
                                  'another-name-space' as "ns1",
                           ), 
                    '/ns/ns1/foo/bar'
                    passing xmltype.createxml(xml) 
                    columns id varchar2(10) path '//ns//ns1/id',
                            idboss varchar2(500) path '//ns0//ns1/idboss',
                            etc....

                    ) nice_xml_table

Hope it helps someone.

This is a PDO-only visualization, as the mysql_* library is deprecated.

<?php
    // Begin Vault (this is in a vault, not actually hard-coded)
    $host="hostname";
    $username="GuySmiley";
    $password="thePassword";
    $dbname="dbname";
    $port="3306";
    // End Vault

    try {
        $dbh = new PDO("mysql:host=$host;port=$port;dbname=$dbname;charset=utf8", $username, $password);
        $dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        echo "I am connected.<br/>";

        // ... continue with your code

        // PDO closes connection at end of script
    } catch (PDOException $e) {
        echo 'PDO Exception: ' . $e->getMessage();
        exit();
    }
?>

Note that this OP Question appeared not to be about port numbers afterall. If you are using the default port of 3306 always, then consider removing it from the uri, that is, remove the port=$port; part.

If you often change ports, consider the above port usage for more maintainability having changes made to the $port variable.

Some likely errors returned from above:

PDO Exception: SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.
PDO Exception: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No such host is known.

In the below error, we are at least getting closer, after changing our connect information:

PDO Exception: SQLSTATE[HY000] [1045] Access denied for user 'GuySmiley'@'localhost' (using password: YES)

After further changes, we are really close now, but not quite:

PDO Exception: SQLSTATE[HY000] [1049] Unknown database 'mustard'

From the Manual on PDO Connections:

with Scanner you need to check if there is a next line with hasNextLine()

so the loop becomes

while(sc.hasNextLine()){
    str=sc.nextLine();
    //...
}

it's readers that return null on EOF

ofcourse in this piece of code this is dependent on whether the input is properly formatted

I like this method:

import datetime, time

dts = datetime.datetime.utcnow()
epochtime = round(time.mktime(dts.timetuple()) + dts.microsecond/1e6)

The other methods posted here are either not guaranteed to give you UTC on all platforms or only report whole seconds. If you want full resolution, this works, to the micro-second.

If we encapsulate that in a function we could use recursion and state clearly the purpose by naming the function properly (not sure if getAny is actually a good name):

def getAny(dic, keys, default=None):
    return (keys or default) and dic.get(keys[0], 
                                         getAny( dic, keys[1:], default=default))

or even better, without recursion and more clear:

def getAny(dic, keys, default=None):
    for k in keys: 
        if k in dic:
           return dic[k]
    return default

Then that could be used in a way similar to the dict.get method, like:

getAny(myDict, keySet)

and even have a default result in case of no keys found at all:

getAny(myDict, keySet, "not found")

As an alternative, you can save old data and create a new table with new parameters.

In SQL Server Management Studio: "your database" => task => generatescripts => select specific database object => "your table" => advanced => types of data to script - schema and data => generate

Personally, I did so.

You could do something along this lines:

def static_example():
   if not hasattr(static_example, "static_var"):
       static_example.static_var = 0
   static_example.static_var += 1
   return static_example.static_var

print static_example()
print static_example()
print static_example()

If you're using bootstrap 3 date time picker, try this:

$('.selector').datetimepicker({ maxDate: $.now() });

Array functional way:

   array.enumerated().filter { $0.offset < limit }.map { $0.element }

ranged:

 array.enumerated().filter { $0.offset >= minLimit && $0.offset < maxLimit }.map { $0.element }

The advantage of this method is such implementation is safe.

This plagued me for over an hour.

If you're using the dataSrc option and column defs option, make sure they are in the correct locations. I had nested column defs in the ajax settings and lost way too much time figuring that out.

This is good:

This is not good:

Subtle difference, but real enough to cause hair loss.

Adding to Eric Jablow's answer, here is a possible solution (it worked for me - linux mint 14 /nadia)

find /path/to/search/ -type f -name "glob-to-find-files" | xargs cp -t /target/path/

You can refer to "How can I use xargs to copy files that have spaces and quotes in their names?" as well.

Firstly, I made an exhaustive cheatsheet of shutil methods for your reference.

shutil_methods =
{'copy':['shutil.copyfileobj',
          'shutil.copyfile',
          'shutil.copymode',
          'shutil.copystat',
          'shutil.copy',
          'shutil.copy2',
          'shutil.copytree',],
 'move':['shutil.rmtree',
         'shutil.move',],
 'exception': ['exception shutil.SameFileError',
                 'exception shutil.Error'],
 'others':['shutil.disk_usage',
             'shutil.chown',
             'shutil.which',
             'shutil.ignore_patterns',]
}

Secondly, explain methods of copy in exmaples:

1. shutil.copyfileobj(fsrc, fdst[, length]) manipulate opened objects

In [3]: src = '~/Documents/Head+First+SQL.pdf'
In [4]: dst = '~/desktop'
In [5]: shutil.copyfileobj(src, dst)
AttributeError: 'str' object has no attribute 'read'
#copy the file object
In [7]: with open(src, 'rb') as f1,open(os.path.join(dst,'test.pdf'), 'wb') as f2:
    ...:      shutil.copyfileobj(f1, f2)
In [8]: os.stat(os.path.join(dst,'test.pdf'))
Out[8]: os.stat_result(st_mode=33188, st_ino=8598319475, st_dev=16777220, st_nlink=1, st_uid=501, st_gid=20, st_size=13507926, st_atime=1516067347, st_mtime=1516067335, st_ctime=1516067345)

2. shutil.copyfile(src, dst, *, follow_symlinks=True) Copy and rename

In [9]: shutil.copyfile(src, dst)
IsADirectoryError: [Errno 21] Is a directory: ~/desktop'
#so dst should be a filename instead of a directory name

3. shutil.copy() Copy without preseving the metadata

In [10]: shutil.copy(src, dst)
Out[10]: ~/desktop/Head+First+SQL.pdf'
#check their metadata
In [25]: os.stat(src)
Out[25]: os.stat_result(st_mode=33188, st_ino=597749, st_dev=16777220, st_nlink=1, st_uid=501, st_gid=20, st_size=13507926, st_atime=1516066425, st_mtime=1493698739, st_ctime=1514871215)
In [26]: os.stat(os.path.join(dst, 'Head+First+SQL.pdf'))
Out[26]: os.stat_result(st_mode=33188, st_ino=8598313736, st_dev=16777220, st_nlink=1, st_uid=501, st_gid=20, st_size=13507926, st_atime=1516066427, st_mtime=1516066425, st_ctime=1516066425)
# st_atime,st_mtime,st_ctime changed

4. shutil.copy2() Copy with preseving the metadata

In [30]: shutil.copy2(src, dst)
Out[30]: ~/desktop/Head+First+SQL.pdf'
In [31]: os.stat(src)
Out[31]: os.stat_result(st_mode=33188, st_ino=597749, st_dev=16777220, st_nlink=1, st_uid=501, st_gid=20, st_size=13507926, st_atime=1516067055, st_mtime=1493698739, st_ctime=1514871215)
In [32]: os.stat(os.path.join(dst, 'Head+First+SQL.pdf'))
Out[32]: os.stat_result(st_mode=33188, st_ino=8598313736, st_dev=16777220, st_nlink=1, st_uid=501, st_gid=20, st_size=13507926, st_atime=1516067063, st_mtime=1493698739, st_ctime=1516067055)
# Preseved st_mtime

5. shutil.copytree()

Recursively copy an entire directory tree rooted at src, returning the destination directory

Unfortunately this isn't entirely possible as the ClassLoader won't tell you what classes are available. You can, however, get fairly close doing something like this:

for (String classpathEntry : System.getProperty("java.class.path").split(System.getProperty("path.separator"))) {
    if (classpathEntry.endsWith(".jar")) {
        File jar = new File(classpathEntry);

        JarInputStream is = new JarInputStream(new FileInputStream(jar));

        JarEntry entry;
        while( (entry = is.getNextJarEntry()) != null) {
            if(entry.getName().endsWith(".class")) {
                // Class.forName(entry.getName()) and check
                //   for implementation of the interface
            }
        }
    }
}

Edit: johnstok is correct (in the comments) that this only works for standalone Java applications, and won't work under an application server.

Query objects in Mongo by default AND expressions together. Mongo currently does not include an OR operator for such queries, however there are ways to express such queries.

Use "in" or "where".

Its gonna be something like this:

db.mycollection.find( { $where : function() { 
return ( this.startTime < Now() && this.expireTime > Now() || this.expireTime == null ); } } );

One option which worked for me on MAC.

Click on the Docker Icon in the tray. Open Preferences -> Proxies. Click on Manual Proxy and specify Web Server (HTTP) proxy and Secure Web server (HTTPS) proxy in the same format as we specify in HTTPS_PROXY env variable. Choose Apply and Restart.

This Worked for me

The difference between constructor and getInitialState is the difference between ES6 and ES5 itself.
getInitialState is used with React.createClass and
constructor is used with React.Component.

Hence the question boils down to advantages/disadvantages of using ES6 or ES5.

Let's look at the difference in code

ES5

var TodoApp = React.createClass({ 
  propTypes: {
    title: PropTypes.string.isRequired
  },
  getInitialState () { 
    return {
      items: []
    }; 
  }
});

ES6

class TodoApp extends React.Component {
  constructor () {
    super()
    this.state = {
      items: []
    }
  }
};

There is an interesting reddit thread regarding this.

React community is moving closer to ES6. Also it is considered as the best practice.

There are some differences between React.createClass and React.Component. For instance, how this is handled in these cases. Read more about such differences in this blogpost and facebook's content on autobinding

constructor can also be used to handle such situations. To bind methods to a component instance, it can be pre-bonded in the constructor. This is a good material to do such cool stuff.

Converting React project from ES5 to ES6

Update: April 9, 2019,:

With the new changes in Javascript class API, you don't need a constructor.

You could do

class TodoApp extends React.Component {

    this.state = {items: []}
};

This will still get transpiled to constructor format, but you won't have to worry about it. you can use this format that is more readable.

With React Hooks

From React version 16.8, there's a new API Called hooks.

Now, you don't even need a class component to have a state. It can even be done in a functional component.

import React, { useState } from 'react';

function TodoApp () {
  const items = useState([]);

Note that the initial state is passed as an argument to useState; useState([])

Slight adjustment to answers from ARobertson and Kenneth Wilson that worked for me.

Running R 3.6.0, with library(tidyverse) and library(dplyr) in my environment:

library(tidyverse)
library(dplyr)
> df %<>% mutate_if(is.character, as.numeric)
Error in df %<>% mutate_if(is.character, as.numeric) : 
  could not find function "%<>%"

I did some quick research and found this note in Hadley's "The tidyverse style guide".

The magrittr package provides the %<>% operator as a shortcut for modifying an object in place. Avoid this operator.

# Good x <- x %>%
           abs() %>%    
           sort()

# Bad x %<>%   
          abs() %>%
          sort()

Solution

Based on that style guide:

df_clean <- df %>% mutate_if(is.character, as.numeric)

Working example

> df_clean <- df %>% mutate_if(is.character, as.numeric)

For DB2:

`VALUES('Hello world')`

You can do multiple "rows" as well:

`VALUES('Hello world'),('Goodbye world');`

You can even use them in joins as long as the types match:

VALUES(1,'Hello world')
UNION ALL
VALUES(2,'Goodbye world');

The .getTimezoneOffset() method should work. This will get the time between your time zone and GMT. You can then calculate to whatever you want.

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 "'")

Classic ASP:

'Is it worth it, let me work it'
'I put my thing down, flip it and reverse it'
'Ti esrever dna ti pilf, nwod gniht ym tup I'

NextIP = StrReverse(UserRecordset.Fields.Item(0))

use <br/> tag

Example:

<string name="copyright"><b>@</b> 2014 <br/>
Corporation.<br/>
<i>All rights reserved.</i></string>

Try to modify the eclipse.ini so that both Xms and Xmx are of the same value:

-Xms6000m
-Xmx6000m

This should force the Eclipse's VM to allocate 6GB of heap right from the beginning.

But be careful about either using the eclipse.ini or the command-line ./eclipse/eclipse -vmargs .... It should work in both cases but pick one and try to stick with it.

if it's a new project, remove existing folder and run $ npm install -g react-native-cli

check that runs without any error

If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:

Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);

Hope it helps.

To be more clear - there's no OneToMany in Django, only ManyToOne - which is Foreignkey described above. You can describe OneToMany relation using Foreignkey but that is very inexpressively.

A good article about it: https://amir.rachum.com/blog/2013/06/15/a-case-for-a-onetomany-relationship-in-django/

Found it here: http://awesomesql.wordpress.com/2010/02/08/script-to-drop-all-connections-to-a-database/

DECLARE @dbname NVARCHAR(128)
SET @dbname = 'DB name here'
 -- db to drop connections 
DECLARE @processid INT 
SELECT  @processid = MIN(spid)
FROM    master.dbo.sysprocesses
WHERE   dbid = DB_ID(@dbname) 
WHILE @processid IS NOT NULL 
    BEGIN 
        EXEC ('KILL ' + @processid) 
        SELECT  @processid = MIN(spid)
        FROM    master.dbo.sysprocesses
        WHERE   dbid = DB_ID(@dbname) 
    END

Use only one server side form tag.

Check your Master page for <form runat="server"> - there should be only one.

Why do you need more than one?

you can create the folder using the following depending on your ansible version.

Latest version 2<

- name: Create Folder
  file: 
   path: "{{project_root}}/conf"
   recurse: yes
   state: directory

Older version:

- name: Create Folder
  file: 
      path="{{project_root}}/conf"
      recurse: yes
      state=directory

Refer - http://docs.ansible.com/ansible/latest/file_module.html

Add this class in .css class

.scrol  { 
font: bold 14px Arial; 
border:1px solid black; 
width:100% ; 
color:#616D7E; 
height:20px; 
overflow:scroll; 
overflow-y:scroll;
overflow-x:hidden;
}

and use the class in div. like here.

<div> <p class = "scrol" id = "title">-</p></div>

I have attached image , you see the out put of the above code

A loading indicator is simply an animated image (.gif) that is displayed until the completed event is called on the AJAX request. http://ajaxload.info/ offers many options for generating loading images that you can overlay on your modals. To my knowledge, Bootstrap does not provide the functionality built-in.

JavaScript

var myObj = {
   id: "c001",
   name: "Hello Test"
}

Result(JSON)

{
   "id": "c001",
   "name": "Hello Test"
}

Please read the $.ajax documentation, this is a covered topic.

$.ajax({
    url: "test.html",
    error: function(){
        // will fire when timeout is reached
    },
    success: function(){
        //do something
    },
    timeout: 3000 // sets timeout to 3 seconds
});

You can get see what type of error was thrown by accessing the textStatus parameter of the error: function(jqXHR, textStatus, errorThrown) option. The options are "timeout", "error", "abort", and "parsererror".

You're going to have to rely on each individual's machine having the correct file associations. If you try and open the application from JavaScript/VBScript in a web page, the spawned application is either going to itself be sandboxed (meaning decreased permissions) or there are going to be lots of security prompts.

My suggestion is to look to SharePoint server for this one. This is something that we know they do and you can edit in place, but the question becomes how they manage to pull that off. My guess is direct integration with Office. Either way, this isn't something that the Internet is designed to do, because I'm assuming you want them to edit the original document and not simply create their own copy (which is what the default behavior of file:// would be.

So depending on you options, it might be possible to create a client side application that gets installed on all your client machines and then responds to a particular file handler that says go open this application on the file server. Then it wouldn't really matter who was doing it since all browsers would simply hand off the request to you. You would have to create your own handler like fileserver://.

In onCreate call

requestWindowFeature(Window.FEATURE_NO_TITLE); // for hiding title

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                            WindowManager.LayoutParams.FLAG_FULLSCREEN);

You can match those three groups separately, and make sure that they all present. Also, [^\w] seems a bit too broad, but if that's what you want you might want to replace it with \W.
