After a bit of trial and error... as mentioned in the possible answers, it turned out to require xfs_growfs rather than resize2fs.

CentOS 7,

fdisk /dev/xvda

Create new primary partition, set type as linux lvm.

n
p
3
t
8e
w

Create a new primary volume and extend the volume group to the new volume.

partprobe
pvcreate /dev/xvda3
vgextend /dev/centos /dev/xvda3

Check the physical volume for free space, extend the logical volume with the free space.

vgdisplay -v
lvextend -l+288 /dev/centos/root

Finally perform an online resize to resize the logical volume, then check the available space.

xfs_growfs /dev/centos/root
df -h

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

This is a more user-friendly one I guess :

#include<stdio.h>

/* This program checks if the entered input is an integer
 * or provides an option for the user to re-enter.
 */

int getint()
{
  int x;
  char c;
  printf("\nEnter an integer (say -1 or 26 or so ): ");
  while( scanf("%d",&x) != 1 )
  {
    c=getchar();

    printf("You have entered ");
    putchar(c);
    printf(" in the input which is not an integer");

    while ( getchar() != '\n' )
     ; //wasting the buffer till the next new line

    printf("\nEnter an integer (say -1 or 26 or so ): ");

  }

return x;
}


int main(void)
{
  int x;
  x=getint();

  printf("Main Function =>\n");
  printf("Integer : %d\n",x);

 return 0;
}

It should be MM for months. You are asking for minutes.

DateTime.Now.ToString("dd/MM/yyyy");

OK, so thanks to all of the contributors above. I am using .NET 4.6 and we also had the same issue. I spent time debugging System.Net.Http, specifically the HttpClientHandler, and found the following:

    if (ExecutionContext.IsFlowSuppressed())
    {
      IWebProxy webProxy = (IWebProxy) null;
      if (this.useProxy)
        webProxy = this.proxy ?? WebRequest.DefaultWebProxy;
      if (this.UseDefaultCredentials || this.Credentials != null || webProxy != null && webProxy.Credentials != null)
        this.SafeCaptureIdenity(state);
    }

So after assessing that the ExecutionContext.IsFlowSuppressed() might have been the culprit, I wrapped our Impersonation code as follows:

using (((WindowsIdentity)ExecutionContext.Current.Identity).Impersonate())
using (System.Threading.ExecutionContext.SuppressFlow())
{
    // HttpClient code goes here!
}

The code inside of SafeCaptureIdenity (not my spelling mistake), grabs WindowsIdentity.Current() which is our impersonated identity. This is being picked up because we are now suppressing flow. Because of the using/dispose this is reset after invocation.

It now seems to work for us, phew!

This is the most common issue faced by Windows users for running Docker Containers. IMO this is the "million dollar question on Docker"; @"Rocco Smit" has rightly pointed out "inbound traffic for it was disabled by default on my host machine's firewall"; in my case, my McAfee Anti Virus software. I added additional ports to be allowed for inbound traffic from other computers on the same Wifi LAN in the Firewall Settings of McAfee; then it was magic. I had struggled for more than a week browsing all over internet, SO, Docker documentations, Tutorials after Tutorials related to the Networking of Docker, and the many illustrations of "not supported on Windows" for "macvlan", "ipvlan", "user defined bridge" and even this same SO thread couple of times. I even started browsing google with "anybody using Docker in Production?", (yes I know Linux is more popular for Prod workloads compared to Windows servers) as I was not able to access (from my mobile in the same Home wifi) an nginx app deployed in Docker Container on Windows. After all, what good it is, if you cannot access the application (deployed on a Docker Container) from other computers / devices in the same LAN at-least; Ultimately in my case, the issue was just with a firewall blocking inbound traffic;

The gcc option -O enables different levels of optimization. Use -O0 to disable them and use -S to output assembly. -O3 is the highest level of optimization.

Starting with gcc 4.8 the optimization level -Og is available. It enables optimizations that do not interfere with debugging and is the recommended default for the standard edit-compile-debug cycle.

To change the dialect of the assembly to either intel or att use -masm=intel or -masm=att.

You can also enable certain optimizations manually with -fname.

Have a look at the gcc manual for much more.

VSCode will never refresh the file if you have changes in that file that are not saved to disk. However, if the file is open and does not have changes, it will replace with the changes on disk, that is true.

There is currently no way to disable this behaviour.

Posting modified function for own reference. This example inserts a selected item from <select> object and puts the caret between the tags:

        for (b = 0; b < vindex; b++) {
            if (visited[b] == randValue) {
                randValue = (rand() % 100) + 1;
                b = 0;
            }
        }

        visited[vindex++] = randValue;
    }

    for (a = 0; a < 100; a++)
        printf("%d ", visited[a]);
}

One main difference is the Local part of LocalDateTime. If you live in Germany and create a LocalDateTime instance and someone else lives in USA and creates another instance at the very same moment (provided the clocks are properly set) - the value of those objects would actually be different. This does not apply to Instant, which is calculated independently from time zone.

LocalDateTime stores date and time without timezone, but it's initial value is timezone dependent. Instant's is not.

Moreover, LocalDateTime provides methods for manipulating date components like days, hours, months. An Instant does not.

apart from the nanosecond precision advantage of Instant and the time-zone part of LocalDateTime

Both classes have the same precision. LocalDateTime does not store timezone. Read javadocs thoroughly, because you may make a big mistake with such invalid assumptions: Instant and LocalDateTime.

There are three types of variables:

• Instance variables: are always initialized
• Static variables: are always initialized
• Local variables: must be initialized before use

The default values for instance and static variables are the same and depends on the type:

• Object type (String, Integer, Boolean and others): initialized with null
• Primitive types:
  • byte, short, int, long: 0
  • float, double: 0.0
  • boolean: false
  • char: '\u0000'

An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.

Once the array is created all of its elements are assiged with the default type value. For example:

private boolean[] list; // default value is null

private Boolean[] list; // default value is null

once is initialized:

private boolean[] list = new boolean[10]; // all ten elements are assigned to false

private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)

Enclose <img> in <a> tag.

<a href="http://www.google.com.pk"><img src="smiley.gif"></a>

it will open link on same tab, and if you want to open link on new tab then use target="_blank"

<a href="http://www.google.com.pk" target="_blank"><img src="smiley.gif"></a>

I installed MVC4 via WPI and it helped me.

Thanks to your answer @RDC.

The following codes works with Swift 3

// MARK: - UICollectionViewDataSource protocol
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {

    //prepare your cell here..
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath as IndexPath) as! MyCell
    cell.myLabel.text =  "my text"

    //Add background view for normal cell
    let backgroundView: UIView = UIView(frame: cell.bounds)
    backgroundView.backgroundColor = UIColor.lightGray
    cell.backgroundView = backgroundView

    //Add background view for selected cell
    let selectedBGView: UIView = UIView(frame: cell.bounds)
    selectedBGView.backgroundColor = UIColor.green
    cell.selectedBackgroundView = selectedBGView

    return cell
}

// MARK: - UICollectionViewDelegate protocol
func collectionView(_ collectionView: UICollectionView, shouldHighlightItemAt indexPath: IndexPath) -> Bool {
    return true
}

func collectionView(_ collectionView: UICollectionView, shouldSelectItemAt indexPath: IndexPath) -> Bool {
    return true
}

You can simply handle the NO_DATA_FOUND exception by setting your variable to NULL. This way, only one query is required.

    v_column my_table.column%TYPE;

BEGIN

    BEGIN
      select column into v_column from my_table where ...;
    EXCEPTION
      WHEN NO_DATA_FOUND THEN
        v_column := NULL;
    END;

    ... use v_column here
END;

Another approach using regex:

''.join(re.split(r'[.;!?,]', s))

After some experimentation (see below), I can confirm that as of September 2017, nothing has changed with regards to the functionality described in the accepted answer:-

1. Rextester demo for Oracle 11g: Empty strings are inserted as NULLs for both VARCHAR and VARCHAR2.
2. LiveSQL demo for Oracle 12c: Same results.

The historical reason for these two keywords is explained well in an answer to a different question.

There is a lack of answers for windows users. Here is how I solved this issue.

First add the PostgreSQL bin folder into the path variable like this

set PATH=%PATH%;C:\Program Files\PostgreSQL\11\bin

Substitute \11\ with your version of Postgres

next run

pip install pyscopg2

this at least got me to a compiling error.

Update: it looks to be an issue with the psycopg2 library and it’s dependencies not playing nice with python 3.8. https://github.com/psycopg/psycopg2/issues/990

I think, best way to use/set boolean value as parameter is to use in your PS script it like this:

Param(
    [Parameter(Mandatory=$false)][ValidateSet("true", "false")][string]$deployApp="false"   
)

$deployAppBool = $false
switch($deployPmCmParse.ToLower()) {
    "true" { $deployAppBool = $true }
    default { $deployAppBool = $false }
}

So now you can use it like this:

.\myApp.ps1 -deployAppBool True
.\myApp.ps1 -deployAppBool TRUE
.\myApp.ps1 -deployAppBool true
.\myApp.ps1 -deployAppBool "true"
.\myApp.ps1 -deployAppBool false
#and etc...

So in arguments from cmd you can pass boolean value as simple string :).

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

It is quite easy to solve your task. You should create and use a new variable for summing values of the "Doctor Payment" column.

In your case the variable can be declared like this:

<variable name="total" class="java.lang.Integer" calculation="Sum">
    <variableExpression><![CDATA[$F{payment}]]></variableExpression>
</variable>

• the Calculation type is Sum;
• the Reset type is Report;
• the Variable expression is $F{payment}, where $F{payment} is the name of a field contains sum (Doctor Payment).

The working example.

doctor_id,payment

I added a class to easily implement menu arguments. So you can customize and include in your function like this:

include_once get_template_directory() . DIRECTORY_SEPARATOR . "your-directory" . DIRECTORY_SEPARATOR . "Menu.php";

<?php $menu = (new Menu('your-theme-location'))
            ->setMenuClass('your-menu')
            ->setMenuID('your-menu-id')
            ->setListClass('your-menu-class')
            ->setLinkClass('your-menu-link anchor') ?>
    
            // Print your menu
            <?php $menu->showMenu() ?>

<?php

class Menu

    private $args = [

        'menu_class' => '',
        'add_li_class' => '',
        'link_class' => ''
    ];

    public function __construct($themeLocation)
    {
        add_filter('nav_menu_css_class', [$this,'add_additional_class_on_li'], 1, 3);
        add_filter( 'nav_menu_link_attributes', [$this,'add_menu_link_class'], 1, 3 );

        $this->args['theme_location'] = $themeLocation;
    }

    public function wrapWithTag($tagName){
        $this->args['container'] = $tagName;

ThisWorkbook.Worksheets("Master").Sheet1.Cells.Copy _
    Destination:=newWorksheet.Cells

The above will copy the cells. If you really want to duplicate the entire sheet, then I'd go with @brettdj's answer.

I liked the answer from @Mahomedalid besides this fact informed in comment from @Bill Karwin. The possible problem raised by @Jan Koritak is true I faced that but I have found a trick for that and just want to share it here for anyone facing the issue.

we can replace the REPLACE function with where clause in the sub-query of Prepared statement like this:

Using my table and column name

SET @SQL = CONCAT('SELECT ', (SELECT GROUP_CONCAT(COLUMN_NAME) FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'users' AND COLUMN_NAME NOT IN ('id')), ' FROM users');
PREPARE stmt1 FROM @SQL;
EXECUTE stmt1;

So, this is going to exclude only the field id but not company_id

set your property using below code at the time of model creation i think your problem will be solved..and the time are not appear in database.you dont need to add any annotation.

private DateTime? dob;
        public DateTime? DOB
        {
            get
            {
                if (dob != null)
                {
                    return dob.Value.Date;
                }
                else
                {
                    return null;
                }

            }
            set { dob = value; }
        }

As you pointed out in your question it is a documented behavior. I still find it strange though. I use to repopulate the test database and even though I do not rely on the values of identity fields it was a bit of annoying to have different values when populating the database for the first time from scratch and after removing all data and populating again.

A possible solution is to use truncate to clean the table instead of delete. But then you need to drop all the constraints and recreate them afterwards

In that way it always behaves as a newly created table and there is no need to call DBCC CHECKIDENT. The first identity value will be the one specified in the table definition and it will be the same no matter if you insert the data for the first time or for the N-th

If you dont want to change the format of date and time from the timestamp, you can use the explode function in php

$timestamp = "2012-04-02 02:57:54"
$datetime = explode(" ",$timestamp);
$date = $datetime[0];
$time = $datetime[1];

the "title" attribute will be used as the text for tooltip by the browser, if you want to apply style to it consider using some plugins

If I understand your issue this should work

&emsp—the em space; this should be a very wide space, typically as much as four real spaces. &ensp—the en space; this should be a somewhat wide space, roughly two regular spaces. &thinsp—this will be a narrow space, even more narrow than a regular space.

For django forms you can do this;

form = UserLoginForm(data=request.POST) #getting the whole data from the user.
user = form.save() #saving the details obtained from the user.
username = user.cleaned_data.get("username") #where "username" in parenthesis is the name of the Charfield (the variale name i.e, username = forms.Charfield(max_length=64))

Simple answer to this; I was trying to figure out the same thing, and it just hit me.

GitHub IS a program installed on your computer, and when it runs, it WILL use threads and RAM. So that makes it a process. All you have to do is open Task Manager, click the Processes tab, find 'Github.exe', right click, Open File Location. Voila! Mine is in some App folder in Local, about 4 layers deep.

What you have is EXTRATERRESTRIAL ALIEN (U+1F47D) and BROKEN HEART (U+1F494) which are not in the basic multilingual plane. They cannot be even represented in java as one char, "".length() == 4. They are definitely not null characters and one will see squares if you are not using fonts that support them.

MySQL's utf8 only supports basic multilingual plane, and you need to use utf8mb4 instead:

For a supplementary character, utf8 cannot store the character at all, while utf8mb4 requires four bytes to store it. Since utf8 cannot store the character at all, you do not have any supplementary characters in utf8 columns and you need not worry about converting characters or losing data when upgrading utf8 data from older versions of MySQL.

So to support these characters, your MySQL needs to be 5.5+ and you need to use utf8mb4 everywhere. Connection encoding needs to be utf8mb4, character set needs to be utf8mb4 and collaction needs to be utf8mb4. For java it's still just "utf-8", but MySQL needs a distinction.

I don't know what driver you are using but a driver agnostic way to set connection charset is to send the query:

SET NAMES 'utf8mb4'

Right after making the connection.

See also this for Connector/J:

14.14: How can I use 4-byte UTF8, utf8mb4 with Connector/J?

To use 4-byte UTF8 with Connector/J configure the MySQL server with character_set_server=utf8mb4. Connector/J will then use that setting as long as characterEncoding has not been set in the connection string. This is equivalent to autodetection of the character set.

Adjust your columns and database as well:

var1 varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NOT NULL

Again, your MySQL version needs to be relatively up-to-date for utf8mb4 support.

Aptana Studio 3 includes such terminal. I found it to be very similar to native terminal compared to what's mentioned in other answers.

Defining r as a dictionary should do the trick:

>>> r: dict = {'is_claimed': 'True', 'rating': 3.5}
>>> print(r['rating'])
3.5
>>> type(r)
<class 'dict'>

run visual studio in admin rights and execute following "commandaspnet_regiis -i"

A Pythonic way to find the index of the maximum list element would be

position = max(enumerate(a), key=lambda x: x[1])[0]

Which does one pass. Yet, it is slower than the solution by @Silent_Ghost and, even more so, @nmichaels:

for i in s m j n; do echo $i;  python -mtimeit -s"import maxelements as me" "me.maxelements_${i}(me.a)"; done
s

A short and elegant way in next Javascript specification (candidate stage 3) is:

obj = { ... obj, ... { key3 : value3 } }

A deeper discussion can be found in Object spread vs Object.assign and on Dr. Axel Rauschmayers site.

It works already in node.js since release 8.6.0.

Vivaldi, Chrome, Opera, and Firefox in up to date releases know this feature also, but Mirosoft don't until today, neither in Internet Explorer nor in Edge.

Use Either Debug.WriteLine() or Trace.WriteLine(). If in release mode, only the latter will appear in the output window, in debug mode, both will.

dplyr package could be nice alternative to this problem:

library(dplyr)

df %>% 
  group_by(group) %>% 
  summarize(mean = mean(dt),
            sum = sum(dt))

To get 1st quadrant and 3rd quadrant

df %>% 
  group_by(group) %>% 
  summarize(q1 = quantile(dt, 0.25),
            q3 = quantile(dt, 0.75))

You can simply use shell commands. If you want to suppress echoing the output, use the "@" sign. For example:

clean:
    @if [ "test" = "test" ]; then\
        echo "Hello world";\
    fi

Note that the closing ";" and "\" are necessary.

easist way is

if(localStorage.test){
console.log("now defined");
}
else{
console.log("undefined");
localStorage.test="defined;"
}

How it works

when you call localStorage.test first time it does not contain any store into localStorage object so it returns undefined else condition triggers. after else triggered i set new variable and again check it contains data so it return data with true in if condition

Make sure the scp command is available on both sides - both on the client and on the server.

BOTH Server and Client, otherwise you will encounter this kind of (weird)error message on your client: scp: command not found or something similar even though though you have it all configured locally.

Expanding on mjswensen's answer, the command without the filter could take minutes, but the filtered command is almost instant.

PowerShell - List local user accounts

Fast way

Get-WmiObject -Class Win32_UserAccount -Filter  "LocalAccount='True'" | select name, fullname

Slow way

Get-WmiObject -Class Win32_UserAccount |? {$_.localaccount -eq $true} | select name, fullname

Cast them to a Number

$('#total_price').val(Number(a)+Number(b));

But before you do that

if (!isNaN($('input[name=service_price]').val()) {...

Here's also nice way to achieve this via UI.

0) Right click on PowerShell icon when on task bar

1) Shift + right click on Windows PowerShell

2) "Run as different user"

Code for set background color, for SolidColor:

button.Background = new SolidColorBrush(Color.FromArgb(Avalue, rValue, gValue, bValue));

I'm late to this discussion but for anyone else. A solution may be to create a list of keys as such.

k = ['a','b','c','d']

Then use pop() in a list comprehension, or for loop, to iterate over the keys and pop one at a time as such.

new_dictionary = [dictionary.pop(x, 'n/a') for x in k]

The 'n/a' is in case the key does not exist, a default value needs to be returned.

You need to add a listener to the request because node.js works asynchronous like that:

request.on('response', function (response) {
  response.on('data', function (chunk) {
    console.log('BODY: ' + chunk);
 });
});

On Unity3d, int.Parse doesn't work well. So I use like bellow.

List<int> intList = new List<int>( Array.ConvertAll(sNumbers.Split(','),
 new Converter<string, int>((s)=>{return Convert.ToInt32(s);}) ) );

Hope this help for Unity3d Users.

Inspite of using all the matchers, I was getting the same issue:

"org.mockito.exceptions.misusing.InvalidUseOfMatchersException: 
Invalid use of argument matchers!
1 matchers expected, 3 recorded:"

It took me little while to figure this out that the method I was trying to mock was a static method of a class(say Xyz.class) which contains only static method and I forgot to write following line:

PowerMockito.mockStatic(Xyz.class);

May be it will help others as it may also be the cause of the issue.

Just for the sake of adding functions to the Date prototype:

In a mutable fashion / style:

Date.prototype.addDays = function(n) {
   this.setDate(this.getDate() + n);
};

// Can call it tomorrow if you want
Date.prototype.nextDay = function() {
   this.addDays(1);
};

Date.prototype.addMonths = function(n) {
   this.setMonth(this.getMonth() + n);
};

Date.prototype.addYears = function(n) {
   this.setFullYear(this.getFullYear() + n);
}

// etc...

var currentDate = new Date();
currentDate.nextDay();

Google search found me this article, and I did not see the following "personal solution" discussed.

My recent annoyance with Python 3.7 on Windows Subsystem for Linux is that: on two machines with the same Pandas library, one gives me segmentation fault and the other reports warning. It was not clear which one was newer, but "re-installing" pandas solves the problem.

Command that I ran on the buggy machine.

conda install pandas

More details: I was running identical scripts (synced through Git), and both are Windows 10 machine with WSL + Anaconda. Here go the screenshots to make the case. Also, on the machine where command-line python will complain about Segmentation fault (core dumped), Jupyter lab simply restarts the kernel every single time. Worse still, no warning was given at all.

Updates a few months later: I quit hosting Jupyter servers on Windows machine. I now use WSL on Windows to fetch remote ports opened on a Linux server and run all my jobs on the remote Linux machine. I have never experienced any execution error for a good number of months :)

//The IMPERATIVE way
int a = ...
int b = ...    

int c = 0; //1. there is mutable data
c = a+b;   //2. statements (our +, our =) are used to update existing data (variable c)

An imperative program = sequence of statements that change existing data.

Focus on WHAT = our mutating data (modifiable values aka variables).

To chain imperative statements = use procedures (and/or oop).

//The FUNCTIONAL way
const int a = ... //data is always immutable
const int b = ... //data is always immutable

//1. declare pure functions; we use statements to create "new" data (the result of our +), but nothing is ever "changed"
int add(x, y) 
{
   return x+y;
} 

//2. usage = call functions to get new data
const int c = add(a,b); //c can only be assigned (=) once (const)

A functional program = a list of functions "explaining" how new data can be obtained.

Focus on HOW = our function add.

To chain functional "statements" = use function composition.

These fundamental distinctions have deep implications.

Serious software has a lot of data and a lot of code.

So same data (variable) is used in multiple parts of the code.

A. In an imperative program, the mutability of this (shared) data causes issues

• code is hard to understand/maintain (since data can be modified in different locations/ways/moments)
• parallelizing code is hard (only one thread can mutate a memory location at the time) which means mutating accesses to same variable have to be serialized = developer must write additional code to enforce this serialized access to shared resources, typically via locks/semaphores

As an advantage: data is really modified in place, less need to copy. (some performance gains)

B. On the other hand, functional code uses immutable data which does not have such issues. Data is readonly so there are no race conditions. Code can be easily parallelized. Results can be cached. Much easier to understand.

As a disadvantage: data is copied a lot in order to get "modifications".

You can always see the console in a different window by opening the Organiser, clicking on the Devices tab, choosing your device and selecting it's console.

Its possible, we can specify onclick event in

When your ssh key is password protected run ssh-add. npm probably hangs somewhere asking for your password.

This link should get you started. Long story short, a div that has been styled to look like a scrollbar is used to catch click-and-drag events. Wired up to these events are methods that scroll the contents of another div which is set to an arbitrary height and typically has a css rule of overflow:scroll (there are variants on the css rules but you get the idea).

I'm all about the learning experience -- but after you've learned how it works, I recommend using a library (of which there are many) to do it. It's one of those "don't reinvent" things...

Try using setAttribute on the result:

result.setAttribute("class","red");

Starting with the System.IO namespace (particularly the File or FileInfo objects) should get you started.

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

body=Hi+there%2bHello+there

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

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

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

uriBuilder.Query = values.ToString();

Console.WriteLine(uriBuilder.ToString());

The result

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

There are a number of possible ways to do this, but have a google for tkprof

There's no GUI... it's entirely command line and possibly a touch intimidating for Oracle beginners; but it's very powerful.

This link looks like a good start:

Note that this information is readily available in the documentation; just press F1. The page you link to deals with Visual Basic .NET, not VBA. While (no pun intended) there is some degree of overlap in syntax between VBA and VB.NET, one can't just assume that the documentation for the one can be applied directly to the other.

Also in the VBA help file:

Tip The Do...Loop statement provides a more structured and flexible way to perform looping.

strtotime('-1 day', strtotime($date))

This returns the number of difference in seconds of the given date and the $date.so you are getting wrong result .

Suppose $date is todays date and -1 day means it returns -86400 as the difference and the when you try using date you will get 1969-12-31 Unix timestamp start date.

Using jQuery's .is( ":focus" )

$(".status").on("click","textarea",function(){
        if ($(this).is( ":focus" )) {
            // fire this step
        }else{
                    $(this).focus();
            // fire this step
    }

There is no "previous" sibling selector unfortunately, but you can possibly still get the same effect by using positioning (e.g. float right). It depends on what you are trying to do.

In my case, I wanted a primarily CSS 5-star rating system. I would need to color (or swap the icon of) the previous stars. By floating each element right, I am essentially getting the same effect (the html for the stars thus must be written 'backwards').

I'm using FontAwesome in this example and swapping between the unicodes of fa-star-o and fa-star http://fortawesome.github.io/Font-Awesome/

CSS:

.fa {
    display: inline-block;
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    line-height: 1;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
}

/* set all stars to 'empty star' */
.stars-container {
    display: inline-block;      
}   

/* set all stars to 'empty star' */
.stars-container .star {
    float: right;
    display: inline-block;
    padding: 2px;
    color: orange;
    cursor: pointer;

}

.stars-container .star:before {
    content: "\f006"; /* fontAwesome empty star code */
}

/* set hovered star to 'filled star' */
.star:hover:before{
    content: "\f005"; /* fontAwesome filled star code */
}

/* set all stars after hovered to'filled star' 
** it will appear that it selects all after due to positioning */
.star:hover ~ .star:before {
    content: "\f005"; /* fontAwesome filled star code */
}

To get your solution try this

string directory = System.IO.Directory.GetParent(System.IO.Directory.GetParent(Environment.CurrentDirectory).ToString()).ToString();

This code is use for when use click on dialogbox that time hidesoftinput and when user click outer side of dialogbox that time both softinput and dialogbox are close.

dialog = new Dialog(act) {
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        // Tap anywhere to close dialog.
        Rect dialogBounds = new Rect();
        getWindow().getDecorView().getHitRect(dialogBounds);
        if (!dialogBounds.contains((int) event.getX(),
                (int) event.getY())) {
            // You have clicked the grey area
            InputMethodManager inputMethodManager = (InputMethodManager) act
                    .getSystemService(act.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(dialog

I get this one all the time. It means that the user started to download a file, and then it either failed, or they cancelled it.

To reproduce the exception try do this yourself - however I'm unaware of any ways to prevent it (except for handling this specific exception only).

You need to decide what the best way forward is depending on your app.

No, you can never instantiate an abstract class. That's the purpose of an abstract class. The getProvider method you are referring to returns a specific implementation of the abstract class. This is the abstract factory pattern.

Uri is serializable, so you can save strings and convert it back when loading

when saving

String str = myUri.toString();

and when loading

Uri myUri = Uri.parse(str);

This work for me.

<input oninvalid="this.setCustomValidity('custom text on invalid')" onchange="this.setCustomValidity('')" required>

onchange is a must!

I think the reason the OPs code does not work is because once you call Remove you are changing the Length of drr. When you call Delete you are not actually deleting the row until AcceptChanges is called. This is why if you want to use Remove you need a separate loop.

Depending on the situation or preference...

string colName = "colName";
string comparisonValue = (whatever it is).ToString();
string strFilter = (dtbl.Columns[colName].DataType == typeof(string)) ? "[" + colName + "]='" + comparisonValue + "'" : "[" + colName + "]=" + comparisonValue;
string strSort = "";

DataRow[] drows = dtbl.Select(strFilter, strSort, DataViewRowState.CurrentRows);

Above used for next two examples

foreach(DataRow drow in drows)
{
   drow.Delete();//Mark a row for deletion.
}
dtbl.AcceptChanges();

OR

foreach(DataRow drow in drows)
{
   dtbl.Rows[dtbl.Rows.IndexOf(drow)].Delete();//Mark a row for deletion.
}
dtbl.AcceptChanges();

OR

List<DataRow> listRowsToDelete = new List<DataRow>();

foreach(DataRow drow in dtbl.Rows)
{
   if(condition to delete)
   {
      listRowsToDelete.Add(drow);
   }
}

foreach(DataRow drowToDelete in listRowsToDelete)
{
   dtbl.Rows.Remove(drowToDelete);// Calling Remove is the same as calling Delete and then calling AcceptChanges
}

Note that if you call Delete() then you should call AcceptChanges() but if you call Remove() then AcceptChanges() is not necessary.

Also, here is a good link on row filter syntax.

Simply, @Id: This annotation specifies the primary key of the entity. 

@GeneratedValue: This annotation is used to specify the primary key generation strategy to use. i.e Instructs database to generate a value for this field automatically. If the strategy is not specified by default AUTO will be used. 

GenerationType enum defines four strategies: 
1. Generation Type . TABLE, 
2. Generation Type. SEQUENCE,
3. Generation Type. IDENTITY   
4. Generation Type. AUTO

GenerationType.SEQUENCE

With this strategy, underlying persistence provider must use a database sequence to get the next unique primary key for the entities. 

GenerationType.TABLE

With this strategy, underlying persistence provider must use a database table to generate/keep the next unique primary key for the entities. 

GenerationType.IDENTITY
This GenerationType indicates that the persistence provider must assign primary keys for the entity using a database identity column. IDENTITY column is typically used in SQL Server. This special type column is populated internally by the table itself without using a separate sequence. If underlying database doesn't support IDENTITY column or some similar variant then the persistence provider can choose an alternative appropriate strategy. In this examples we are using H2 database which doesn't support IDENTITY column.

GenerationType.AUTO
This GenerationType indicates that the persistence provider should automatically pick an appropriate strategy for the particular database. This is the default GenerationType, i.e. if we just use @GeneratedValue annotation then this value of GenerationType will be used.

just combine the value and the stud_name e.g. 1_sre and split the value when get it into php. Javascript seems like hammer to crack a nut. N.B. this method assumes you can edit the the html. Here is what the html might look like:

<form name='add'>
Age: <select name='age'>
     <option value='1_sre'>23</option>
     <option value='2_sam>24</option>
     <option value='5_john>25</option>
     </select>
<input type='submit' name='submit'/>
</form>

You can also turn on WCF logging for more information about the original error. This helped me solve this problem.

Add the following to your web.config, it saves the log to C:\log\Traces.svclog

<system.diagnostics>
    <sources>
        <source name="System.ServiceModel"
                  switchValue="Information, ActivityTracing"
                  propagateActivity="true">
            <listeners>
                <add name="traceListener"
                     type="System.Diagnostics.XmlWriterTraceListener"
                     initializeData= "c:\log\Traces.svclog" />
            </listeners>
        </source>
    </sources>
</system.diagnostics>

I came across this code snippet that solves it.

//Creating a sample ArrayList 
List<Long> list = new ArrayList<Long>();

//Adding some long type values
list.add(100l);
list.add(200l);
list.add(300l);

//Converting the ArrayList to a Long
Long[] array = (Long[]) list.toArray(new Long[list.size()]);

//Printing the results
System.out.println(array[0] + " " + array[1] + " " + array[2]);

The conversion works as follows:

1. It creates a new Long array, with the size of the original list
2. It converts the original ArrayList to an array using the newly created one
3. It casts that array into a Long array (Long[]), which I appropriately named 'array'

Numpy arrays do not have an append method. Use the Numpy append function instead:

import numpy as np

array_3 = np.append(array_1, array_2, axis=n)
# you can either specify an integer axis value n or remove the keyword argument completely

For example, if array_1 and array_2 have the following values:

array_1 = np.array([1, 2])
array_2 = np.array([3, 4])

If you call np.append without specifying an axis value, like so:

array_3 = np.append(array_1, array_2)

array_3 will have the following value:

array([1, 2, 3, 4])

Else, if you call np.append with an axis value of 0, like so:

array_3 = np.append(array_1, array_2, axis=0)

array_3 will have the following value:

 array([[1, 2],
        [3, 4]]) 

More information on the append function here: https://docs.scipy.org/doc/numpy/reference/generated/numpy.append.html

XLS is a binary proprietary format used by Microsoft. Parsing XLS with server side languages is very difficult without using some specific library or Office Interop. Doing this with javascript is mission impossible. Thanks to the HTML5 File API you can read its binary contents but in order to parse and interpret it you will need to dive into the specifications of the XLS format. Starting from Office 2007, Microsoft embraced the Open XML file formats (xslx for Excel) which is a standard.

write

sudo apt-get install net-tools

char[] ch = ?
new String(ch).getBytes();

or

new String(ch).getBytes("UTF-8");

to get non-default charset.

Update: Since Java 7: new String(ch).getBytes(StandardCharsets.UTF_8);

An index is an on-disk structure associated with a table or view that speeds retrieval of rows from the table or view. An index contains keys built from one or more columns in the table or view. These keys are stored in a structure (B-tree) that enables SQL Server to find the row or rows associated with the key values quickly and efficiently.

Indexes are automatically created when PRIMARY KEY and UNIQUE constraints are defined on table columns. For example, when you create a table with a UNIQUE constraint, Database Engine automatically creates a nonclustered index.

If you configure a PRIMARY KEY, Database Engine automatically creates a clustered index, unless a clustered index already exists. When you try to enforce a PRIMARY KEY constraint on an existing table and a clustered index already exists on that table, SQL Server enforces the primary key using a nonclustered index.

Please refer to this for more information about indexes (clustered and non clustered): https://docs.microsoft.com/en-us/sql/relational-databases/indexes/clustered-and-nonclustered-indexes-described?view=sql-server-ver15

Hope this helps!

You can use the ESCAPE keyword with LIKE. Simply prepend the desired character (e.g. '!') to each of the existing % signs in the string and then add ESCAPE '!' (or your character of choice) to the end of the query.

For example:

SELECT *
FROM prices
WHERE discount LIKE '%80!% off%'
ESCAPE '!'

This will make the database treat 80% as an actual part of the string to search for and not 80(wildcard).

MSDN Docs for LIKE

Just use the * before it:

set<unsigned long>::iterator it;
for (it = myset.begin(); it != myset.end(); ++it) {
    cout << *it;
}

This dereferences it and allows you to access the element the iterator is currently on.

jQuery 1.6+

jQuery('selector').prop("tagName").toLowerCase()

Older versions

jQuery('selector').attr("tagName").toLowerCase()

toLowerCase() is not mandatory.

With defining the file to import it's possible to use all folders common definitions.

So, @import "style/*" will compile all the files in the style folder.

}

Similar to other posts, but with an important distinction to make this work inside a div. The simpler answers aren't very copy-paste-able because they directly modify div or draw over the entire page.

The key here is that the containing div dividedbox has relative positioning, allowing it to sit nicely in your document with the other elements, while the quarters within have absolute positioning, giving you vertical/horizontal control inside the containing div.

As a bonus, text is responsively centered in the quarters.

HTML:

<head>
  <meta charset="utf-8">
  <title>Box model</title>
  <link rel="stylesheet" href="style.css">
</head>

<body>
  <h1 id="title">Title Bar</h1>
  <div id="dividedbox">
    <div class="quarter" id="NW">
      <p>NW</p>
    </div>
    <div class="quarter" id="NE">
      <p>NE</p>
    </div>
    <div class="quarter" id="SE">
      <p>SE</p>
    </div>?
    <div class="quarter" id="SW">
      <p>SW</p>
    </div>
  </div>
</body>

</html>

CSS:

html, body { height:95%;} /* Important to make sure your divs have room to grow in the document */
#title { background: lightgreen}
#dividedbox { position: relative; width:100%; height:95%}   /* for div growth */
.quarter {position: absolute; width:50%; height:50%;  /* gives quarters their size */
  display: flex; justify-content: center; align-items: center;} /* centers text */
#NW { top:0;    left:0;     background:orange;     }
#NE { top:0;    left:50%;   background:lightblue;  }
#SW { top:50%;  left:0;     background:green;      }
#SE { top:50%;  left:50%;   background:red;        }

There is a another way also

1. step 1: create a sample.html file
2. step 2: create a div tag with some id=loadhtml Eg : <div id="loadhtml"></div>

3. step 3: in Any Controller

       var htmlcontent = $('#loadhtml ');
       htmlcontent.load('/Pages/Common/contact.html')
       $compile(htmlcontent.contents())($scope);
   

This Will Load a html page in Current page

I tried the above answer - using page.html#ID_name it gave me a 404 page doesn't exist error.

Then instead of using .html, I simply put a slash / before the # and that worked fine. So my example on the sending page between the link tags looks like:

<a href= "http://my website.com/target-page/#El_Chorro">El Chorro</a>

Just use / instead of .html.

If your widget is a Button:

<LinearLayout android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:weightSum="2"
    android:orientation="horizontal">
    <Button android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="somebutton"/>

    <TextView android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"/>
</LinearLayout>

I'm assuming you want your widget to take up one half, and another widget to take up the other half. The trick is using a LinearLayout, setting layout_width="fill_parent" on both widgets, and setting layout_weight to the same value on both widgets as well. If there are two widgets, both with the same weight, the LinearLayout will split the width between the two widgets.

You need to publish the exposed ports by using the following options:

-P (upper case) or --publish-all that will tell Docker to use random ports from your host and map them to the exposed container's ports.

-p (lower case) or --publish=[] that will tell Docker to use ports you manually set and map them to the exposed container's ports.

The second option is preferred because you already know which ports are mapped. If you use the first option then you will need to call docker inspect demo and check which random ports are being used from your host at the Ports section.

Just run the following command:

docker run -it -p 8080:8080 demo

After that your url will work.

You get the error because if can only evaluate a logical vector of length 1.

Maybe you miss the difference between & (|) and && (||). The shorter version works element-wise and the longer version uses only the first element of each vector, e.g.:

c(TRUE, TRUE) & c(TRUE, FALSE)
# [1] TRUE FALSE

# c(TRUE, TRUE) && c(TRUE, FALSE)
[1] TRUE

You don't need the if statement at all:

mut1 <- trip$Ref.y=='G' & trip$Variant.y=='T'|trip$Ref.y=='C' & trip$Variant.y=='A'
trip[mut1, "mutType"] <- "G:C to T:A"

Yes, there is a maximum, but it's system dependent. Try it and see, doubling until you hit a limit then searching down. At least with Sun JRE 1.6 on linux you get interesting if not always informative error messages (peregrino is netbook running 32 bit ubuntu with 2G RAM and no swap):

peregrino:$ java -Xmx4096M -cp bin WheelPrimes 
Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Could not create the Java virtual machine.

peregrino:$ java -Xmx4095M -cp bin WheelPrimes 
Error occurred during initialization of VM
Incompatible minimum and maximum heap sizes specified

peregrino:$ java -Xmx4092M -cp bin WheelPrimes 
Error occurred during initialization of VM
The size of the object heap + VM data exceeds the maximum representable size

peregrino:$ java -Xmx4000M -cp bin WheelPrimes 
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

(experiment reducing from 4000M until)

peregrino:$ java -Xmx2686M -cp bin WheelPrimes 
(normal execution)

Most are self explanatory, except -Xmx4095M which is rather odd (maybe a signed/unsigned comparison?), and that it claims to reserve 2686M on a 2GB machine with no swap. But it does hint that the maximum size is 4G not 2G for a 32 bit VM, if the OS allows you to address that much.

Try this. Note there's no database specified - it just runs "on the server"

psql -U postgres -c "drop database databasename"

If that doesn't work, I have seen a problem with postgres holding onto orphaned prepared statements.
To clean them up, do this:

SELECT * FROM pg_prepared_xacts;

then for every id you see, run this:

ROLLBACK PREPARED '<id>';

You could use the undocumented

DBCC LOG(databasename, typeofoutput)

where typeofoutput:

0: Return only the minimum of information for each operation -- the operation, its context and the transaction ID. (Default)
1: As 0, but also retrieve any flags and the log record length.
2: As 1, but also retrieve the object name, index name, page ID and slot ID.
3: Full informational dump of each operation.
4: As 3 but includes a hex dump of the current transaction log row.

For example, DBCC LOG(database, 1)

You could also try fn_dblog.

For rolling back a transaction using the transaction log I would take a look at Stack Overflow post Rollback transaction using transaction log.

Instead of entering "EST" for the timezone you can enter "EST5EDT" as such. As you noted, just "EDT" does not work. This will account for the daylight savings time issue. The code line looks like this:

Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("EST5EDT"));

var val = (string === "true");

try with this.

Protected Sub SqlDataSource_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles SqlDataSource.Selecting

    e.Command.CommandText = "SELECT [ImageID],[ImagePath] FROM [TblImage] where IsActive = 1"

    End Sub

You can use cut:

cut -c N- file.txt > new_file.txt

-c: characters

file.txt: input file

new_file.txt: output file

N-: Characters from N to end to be cut and output to the new file.

Can also have other args like: 'N' , 'N-M', '-M' meaning nth character, nth to mth character, first to mth character respectively.

This will perform the operation to each line of the input file.

1. Start cmd
2. Go to the "C:\Program Files\MySQL\MySQL Server 5.6\bin"
3. type mysqld --install

I know it's old, but you can:

• Create a service layer
• Move method there
• Call method in both controllers

you can also use like that

   numbers:Array<any> = [];
   constructor() {
      this.numbers = Array.from({length:10},(v,k)=>k+1);
   }
}

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

Another version of Singleton where the following line of code creates the Singleton instance at the time of application startup.

private static readonly Singleton singleInstance = new Singleton();

Here CLR (Common Language Runtime) will take care of object initialization and thread safety. That means we will not require to write any code explicitly for handling the thread safety for a multithreaded environment.

"The Eager loading in singleton design pattern is nothing a process in which we need to initialize the singleton object at the time of application start-up rather than on demand and keep it ready in memory to be used in future."

public sealed class Singleton
    {
        private static int counter = 0;
        private Singleton()
        {
            counter++;
            Console.WriteLine("Counter Value " + counter.ToString());
        }
        private static readonly Singleton singleInstance = new Singleton(); 

        public static Singleton GetInstance
        {
            get
            {
                return singleInstance;
            }
        }
        public void PrintDetails(string message)
        {
            Console.WriteLine(message);
        }
    }

from main :

static void Main(string[] args)
        {
            Parallel.Invoke(
                () => PrintTeacherDetails(),
                () => PrintStudentdetails()
                );
            Console.ReadLine();
        }
        private static void PrintTeacherDetails()
        {
            Singleton fromTeacher = Singleton.GetInstance;
            fromTeacher.PrintDetails("From Teacher");
        }
        private static void PrintStudentdetails()
        {
            Singleton fromStudent = Singleton.GetInstance;
            fromStudent.PrintDetails("From Student");
        }

If you want to count the number of records in your table, simply run:

    SELECT COUNT(*) FROM your_table;

   /* worked for me  */
     <div id="divid"> </div>
     <script type="text/javascript">
         var hold = document.getElementById("divid");
         var checkbox = document.createElement('input');
         checkbox.type = "checkbox";
         checkbox.name = "chkbox1";
         checkbox.id = "cbid";
         var label = document.createElement('label');
         var tn = document.createTextNode("Not A RoBot");
         label.htmlFor="cbid";
         label.appendChild(tn); 
         hold.appendChild(label);
         hold.appendChild(checkbox);
      </script>  

You can't style an actual title attribute

How the text in the title attribute is displayed is defined by the browser and varies from browser to browser. It's not possible for a webpage to apply any style to the tooltip that the browser displays based on the title attribute.

However, you can create something very similar using other attributes.

You can make a pseudo-tooltip with CSS and a custom attribute (e.g. data-title)

For this, I'd use a data-title attribute. data-* attributes are a method to store custom data in DOM elements/HTML. There are multiple ways of accessing them. Importantly, they can be selected by CSS.

Given that you can use CSS to select elements with data-title attributes, you can then use CSS to create :after (or :before) content that contains the value of the attribute using attr().

Styled tooltip Examples

Bigger and with a different background color (per question's request):

[data-title]:hover:after {_x000D_
    opacity: 1;_x000D_
    transition: all 0.1s ease 0.5s;_x000D_
    visibility: visible;_x000D_
}_x000D_
[data-title]:after {_x000D_
    content: attr(data-title);_x000D_
    background-color: #00FF00;_x000D_
    color: #111;_x000D_
    font-size: 150%;_x000D_
    position: absolute;_x000D_
    padding: 1px 5px 2px 5px;_x000D_

[data-title] {_x000D_
    position: relative;_x000D_
}

<a href="example.com" data-title="My site"> Link </a> with styled tooltip (bigger and with a different background color, as requested in the question)<br/>_x000D_

Known issues

Unlike a real title tooltip, the tooltip produced by the above CSS is not, necessarily, guaranteed to be visible on the page (i.e. it might be outside the visible area). On the other hand, it is guaranteed to be within the current window, which is not the case for an actual tooltip.

In addition, the pseudo-tooltip is positioned relative to the element that has the pseudo-tooltip rather than relative to where the mouse is on that element. You may want to fine-tune where the pseudo-tooltip is displayed. Having it appear in a known location relative to the element can be a benefit or a drawback, depending on the situation.

You can't use :before or :after on elements which are not containers

There's a good explanation in this answer to "Can I use a :before or :after pseudo-element on an input field?"

Effectively, this means that you can't use this method directly on elements like <input type="text"/>, <textarea/>, <img>, etc. The easy solution is to wrap the element that's not a container in a <span> or <div> and have the pseudo-tooltip on the container.

Examples of using a pseudo-tooltip on a <span> wrapping a non-container element:

[data-title]:hover:after {_x000D_
    opacity: 1;_x000D_
    transition: all 0.1s ease 0.5s;_x000D_
    visibility: visible;_x000D_
}_x000D_
[data-title]:after {_x000D_
    content: attr(data-title);_x000D_
    background-color: #00FF00;_x000D_
    color: #111;_x000D_
    font-size: 150%;_x000D_
    position: absolute;_x000D_
    padding: 1px 5px 2px 5px;_x000D_
    bottom: -1.6em;_x000D_
    left: 100%;_x000D_
    white-space: nowrap;_x000D_
    box-shadow: 1px 1px 3px #222222;_x000D_
    opacity: 0;_x000D_
    border: 1px solid #111111;_x000D_
    z-index: 99999;_x000D_
    visibility: hidden;_x000D_
}_x000D_
[data-title] {_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.pseudo-tooltip-wrapper {_x000D_
    /*This causes the wrapping element to be the same size as what it contains.*/_x000D_
    display: inline-block;_x000D_
}

Text input with a pseudo-tooltip:<br/>_x000D_
<span class="pseudo-tooltip-wrapper" data-title="input type=&quot;text&quot;"><input type='text'></span><br/><br/><br/>_x000D_
Textarea with a pseudo-tooltip:<br/>_x000D_
<span class="pseudo-tooltip-wrapper" data-title="this is a textarea"><textarea data-title="this is a textarea"></textarea></span><br/>

^{From the code on the blog post linked above (which I first saw in an answer here that plagiarized it), it appeared obvious to me to use a data-* attribute instead of the title attribute. Doing so was also suggested in a comment by snostorm on that (now deleted) answer.}

Following solution can be pretty useful in the usual login / main activity scenario or implementing a blocking screen.

To minimize the app rather than going back to previous activity, you can override onBackPressed() like this:

@Override
public void onBackPressed() {
    moveTaskToBack(true);
}

moveTaskToBack(boolean nonRoot) leaves your back stack as it is, just puts your task (all activities) in background. Same as if user pressed Home button.

Parameter boolean nonRoot - If false then this only works if the activity is the root of a task; if true it will work for any activity in a task.

You could do this:

if( ctrl[0].nodeName.toLowerCase() === 'input' ) {
    // it was an input
}

or this, which is slower, but shorter and cleaner:

if( ctrl.is('input') ) {
    // it was an input
}

If you want to be more specific, you can test the type:

if( ctrl.is('input:text') ) {
    // it was an input
}

If you are truly looking to replicate Contains, but for an array, here is an extension method and sample code for usage:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ContainsAnyThingy
{
    class Program
    {
        static void Main(string[] args)
        {
            string testValue = "123345789";

            //will print true
            Console.WriteLine(testValue.ContainsAny("123", "987", "554")); 

            //but so will this also print true
            Console.WriteLine(testValue.ContainsAny("1", "987", "554"));
            Console.ReadKey();

        }
    }

    public static class StringExtensions
    {
        public static bool ContainsAny(this string str, params string[] values)
        {
            if (!string.IsNullOrEmpty(str) || values.Length > 0)
            {
                foreach (string value in values)
                {
                    if(str.Contains(value))
                        return true;
                }
            }

            return false;
        }
    }
}

You can get the value like this:

this['inputname'].value

Where this refers to the form that contains the input.

Note: When you pass setDate, you are calling a method which assumes the datepicker has already been initialized on that object.

$(function() {    
   $('#date').datepicker();
   $('#date').datepicker('setDate', '04/23/2014');
});

Test: http://jsfiddle.net/wimarbueno/hQkec/1/

if you can control creating/passing the settings object, i'd recommend using an ExpandoObject instead.

dynamic settings = new ExpandoObject();
settings.Filename = "asdf.txt";
settings.Size = 10;
...

function void Settings(dynamic settings)
{
    if ( ((IDictionary<string, object>)settings).ContainsKey("Filename") )
        .... do something ....
}

See my answer to this question: Detect support for background-attachment: fixed?

• Detecting touch capability alone doesn't work for laptops with touch screens, and the code for detecting touch giving by Christina will fail on some devices.
• Hector's answer will work, but the animation will be very choppy, so it'll look better to replace fixed with scrolling on devices that don't support fixed.
• Unfortunately, Taylon is incorrect that iOS 5+ supports background-attachment:fixed. It does not. I can't find any list of devices that don't support fixed backgrounds. It's likely that most mobile phone and tablets do not.

when you use Interface Builder, you can use Connections Inspector to set up the events with event handlers, the event handlers are supposed to be the functions that have the IBAction modifier. A view can be linked with the reference for the same type and with the IBOutlet modifier.

To my knowledge the setTimeout function is called asynchronously. What you can do is wrap the entire loop within an async function and await a Promise that contains the setTimeout as shown:

var looper = async function () {
  for (var start = 1; start < 10; start++) {
    await new Promise(function (resolve, reject) {
      setTimeout(function () {
        console.log("iteration: " + start.toString());
        resolve(true);
      }, 1000);
    });
  }
  return true;
}

And then you call run it like so:

looper().then(function(){
  console.log("DONE!")
});

Please take some time to get a good understanding of asynchronous programming.

try {
} catch (javax.script.ScriptException ex) {
// System.out.println(ex.getMessage());
}

What are disadvantages of the following solution? Seems to be faster and shorter.

var options = {
    set0: ['Option 1','Option 2'],
    set1: ['First Option','Second Option','Third Option']
};

var list = "<li>" + options.set0.join("</li><li>") + "</li>";
document.getElementById("list").innerHTML = list;

I have seen IFRAMEs applied very successfully as an easy way to make dynamic context menus, but the target audience of that web-app was only Internet Explorer users.

I would say that it all depends on your requirements. If you wish to make sure your page works equally well on every browser, avoid IFRAMEs. If you are targeting a narrow and well-known audience (eg. on the local Intranet) and you see a benefit in using IFRAMEs then I would say it's OK to do so.

For one-line guys:

const htmlDecode = innerHTML => Object.assign(document.createElement('textarea'), {innerHTML}).value;

console.log(htmlDecode('Complicated - Dimitri Vegas & Like Mike'));

Upgrading to Tensorflow 2.0 using pip. Requires Python > 3.4 and pip >= 19.0

not really sure what you're doing exactly via the context of your code but...

why make the listOfTopicAuthors variable at all?

List<String> list = Arrays.asList((....).toArray( new String[0] ) );

the "...." represents however your set came into play, whether it's new or came from another location.

Replace the startsWith function with:

yourString.indexOf(searchString, position) // where position can be set to 0

This will support all browsers including IE

Position can be set to 0 for string matching from the start meaning 0th position.

If your form inside div simply contains form inputting elements, then this simple query will disable every element inside form tag:

<div id="myForm">
    <form action="">
    ...
    </form>
</div>

However, it will also disable other than inputting elements in form, as it's effects will only be seen on input type elements, therefore suitable majorly for every type of forms!

$('#myForm *').attr('disabled','disabled');

You also have to delete the local branch:

git branch -d 6796

Another way is to prune all stale branches from your local repository. This will delete all local branches that already have been removed from the remote:

git remote prune origin --dry-run

Don't forget to call sizeToFit() after you change image if you then use size of UIImageView to set UIScrollView contentSize and/or compute zoom scale

let image = UIImage(named: "testImage")
imageView.image = image
imageView.sizeToFit()
scrollView.contentSize = imageView.bounds.size

Reading the original comment, rutherford is looking for a cross-browser way to wrap unbroken text (inferred by his use of word-wrap for IE, designed to break unbroken strings).

/* Source: http://snipplr.com/view/10979/css-cross-browser-word-wrap */
.wordwrap { 
   white-space: pre-wrap;      /* CSS3 */   
   white-space: -moz-pre-wrap; /* Firefox */    
   white-space: -pre-wrap;     /* Opera <7 */   
   white-space: -o-pre-wrap;   /* Opera 7 */    
   word-wrap: break-word;      /* IE */
}

I've used this class for a bit now, and works like a charm. (note: I've only tested in FireFox and IE)

CSS doesn't really do what you're asking. If you want to write rules with that composite idea in mind, you may want to check out compass. It's a stylesheet framework which looks similar to the already mentioned Less.

It lets you do mixins and all that good business.

The virtual mechanism only works when you have a based class pointer to a derived class object. Construction has it's own rules for the calling of base class constructors, basically base class to derived. How could a virtual constructor be useful or called? I don't know what other languages do, but I can't see how a virtual constructor could be useful or even implemented. Construction needs to have taken place for the virtual mechanism to make any sense and construction also needs to have taken place for the vtable structures to have been created which provides the mechanics of the polymorphic behaviour.

We draw a solid line if and only if we have an ID-dependent relationship; otherwise it would be a dashed line.

Consider a weak but not ID-dependent relationship; We draw a dashed line because it is a weak relationship.

If you want to run some action against the filename only, using basename can be tough.

For example this:

find ~/clang+llvm-3.3/bin/ -type f -exec echo basename {} \; 

will just echo basename /my/found/path. Not what we want if we want to execute on the filename.

But you can then xargs the output. for example to kill the files in a dir based on names in another dir:

cd dirIwantToRMin;
find ~/clang+llvm-3.3/bin/ -type f -exec basename {} \; | xargs rm

For people who find this via search engines, you do not need VBA. You can just:

1.) select the query or table with your mouse
2.) click export data from the ribbon
3.) click excel from the export subgroup
4.) follow the wizard to select the output file and location.

This hasn't solved my problem too, so I changed the parameters slightly.
This code worked for me:

var dataValue = "{ name: 'person', isGoing: 'true', returnAddress: 'returnEmail' }";

$.ajax({
    type: "POST",
    url: "Default.aspx/OnSubmit",
    data: dataValue,
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    error: function (XMLHttpRequest, textStatus, errorThrown) {
        alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
    },
    success: function (result) {
        alert("We returned: " + result.d);
    }
});

Description

You can do this using jQuery.offset() and jQuery.animate().

Check out the jsFiddle Demonstration.

Sample

function scrollToAnchor(aid){
    var aTag = $("a[name='"+ aid +"']");
    $('html,body').animate({scrollTop: aTag.offset().top},'slow');
}

scrollToAnchor('id3');

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

A foreach loop in php will iterate over a copy of the original array, making next() and prev() functions useless. If you have an associative array and need to fetch the next item, you could iterate over the array keys instead:

foreach (array_keys($items) as $index => $key) {
    // first, get current item
    $item = $items[$key];
    // now get next item in array
    $next = $items[array_keys($items)[$index + 1]];
}

Since the resulting array of keys has a continuous index itself, you can use that instead to access the original array.

Be aware that $next will be null for the last iteration, since there is no next item after the last. Accessing non existent array keys will throw a php notice. To avoid that, either:

1. Check for the last iteration before assigning values to $next
2. Check if the key with index + 1 exists with array_key_exists()

Using method 2 the complete foreach could look like this:

foreach (array_keys($items) as $index => $key) {
    // first, get current item
    $item = $items[$key];
    // now get next item in array
    $next = null;
    if (array_key_exists($index + 1, array_keys($items))) {
        $next = $items[array_keys($items)[$index + 1]];
    }
}

Since your content-type is application/x-www-form-urlencoded you'll need to encode the POST body, especially if it contains characters like & which have special meaning in a form.

Try passing your string through HttpUtility.UrlEncode before writing it to the request stream.

Here are a couple links for reference.

Have you tried loading all the initialization functions using the $().ready, running the jQuery function you wanted last?

Perhaps you can use setTimeout() on the $().ready function you wanted to run, calling the functionality you wanted to load.

Or, use setInterval() and have the interval check to see if all the other load functions have completed (store the status in a boolean variable). When conditions are met, you could cancel the interval and run the load function.

Yes, it is sufficient. The way injection type attacks work, is by somehow getting an interpreter (The database) to evaluate something, that should have been data, as if it was code. This is only possible if you mix code and data in the same medium (Eg. when you construct a query as a string).

Parameterised queries work by sending the code and the data separately, so it would never be possible to find a hole in that.

You can still be vulnerable to other injection-type attacks though. For example, if you use the data in a HTML-page, you could be subject to XSS type attacks.

if one of the column is number i have experienced the oracle will think '+' as sum operator instead concatenation.

eg:

select (id + name) as one from table 1; (id is numeric) 

throws invalid number exception

in such case you can || operator which is concatenation.

select (id || name) as one from table 1;

Real life example; find all but not current user:

var players = Players.find({ my_x: player.my_x,  my_y: player.my_y, userId: {$ne: Meteor.userId()} }); 

You can also get content such as the first pagagraph via DBPedia which takes Wikipedia content and creates structured information from it (RDF) and makes this available via an API. The DBPedia API is a SPARQL one (RDF-based) but it outputs JSON and it is pretty easy to wrap.

As an example here's a super simple JS library named WikipediaJS that can extract structured content including a summary first paragraph: http://okfnlabs.org/wikipediajs/

You can read more about it in this blog post: http://okfnlabs.org/blog/2012/09/10/wikipediajs-a-javascript-library-for-accessing-wikipedia-article-information.html

The JS library code can be found here: https://github.com/okfn/wikipediajs/blob/master/wikipedia.js

I know this may seem obvious but I also had to use a single quote around the u/n and p/w before it worked

mongo admin -u 'user' -p 'password'

I see in your code that you are trying to pass an ARRAY to POST action. In that case follow below working code -

<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
    function submitForm() {
        var roles = ["role1", "role2", "role3"];

        jQuery.ajax({
            type: "POST",
            url: "@Url.Action("AddUser")",
            dataType: "json",
            contentType: "application/json; charset=utf-8",
            data: JSON.stringify(roles),
            success: function (data) { alert(data); },
            failure: function (errMsg) {
                alert(errMsg);
            }
        });
    }
</script>

<input type="button" value="Click" onclick="submitForm()"/>

And the controller action is going to be -

    public ActionResult AddUser(List<String> Roles)
    {
        return null;
    }

Then when you click on the button -

The issue of being forced to trigger('change') drove me nuts, as I had custom code in the change trigger, which should only trigger when the user changes the option in the dropdown. IMO, change should not be triggered when setting an init value at the start.

I dug deep and found the following: https://github.com/select2/select2/issues/3620

Example:

$dropDown.val(1).trigger('change.select2');

For putting a whole pdf in your file and not just 1 page, use:

\usepackage{pdfpages}

\includepdf[pages=-]{myfile.pdf}

Do yourself a favor by dropping the Windows compatibility layer.

The normal shortcut for entering Visual-Block mode is <C-v>.

Others have dealt with recording macros, here are a few other ideas:

Using only visual-block mode.

1. Put the cursor on the second word:

   asd |a|sd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   

2. Hit <C-v> to enter visual-block mode and expand your selection toward the bottom:

   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   asd [a]sd asd asd asd;
   

3. Hit I"<Esc> to obtain:

   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   

4. Put the cursor on the last char of the third word:

   asd "asd as|d| asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   asd "asd asd asd asd;
   

5. Hit <C-v> to enter visual-block mode and expand your selection toward the bottom:

   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   asd "asd as[d] asd asd;
   

6. Hit A"<Esc> to obtain:

   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   

With visual-block mode and Surround.vim.

1. Put the cursor on the second word:

   asd |a|sd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   asd asd asd asd asd;
   

2. Hit <C-v> to enter visual-block mode and expand your selection toward the bottom and the right:

   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   asd [asd asd] asd asd;
   

3. Hit S" to surround your selection with ":

   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   

With visual-line mode and :normal.

1. Hit V to select the whole line and expand it toward the bottom:

   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   [asd asd asd asd asd;]
   

2. Execute this command: :'<,'>norm ^wi"<C-v><Esc>eea"<CR> to obtain:

   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   asd "asd asd" asd asd;
   

   • :norm[al] allows you to execute normal mode commands on a range of lines (the '<,'> part is added automatically by Vim and means "act on the selected area")

   • ^ puts the cursor on the first char of the line

   • w moves to the next word

   • i" inserts a " before the cursor

   • <C-v><Esc> is Vim's way to input a control character in this context, here it's <Esc> used to exit insert mode

   • ee moves to the end of the next word

   • a" appends a " after the cursor

   • <CR> executes the command

   Using Surround.vim, the command above becomes

   :'<,'>norm ^wvees"<CR>
   

I hit this error because I needed to give my present working directory permissions 700:

You can date compare as most simple and understandable way like.

<input type="date" id="getdate1" />
<input type="date" id="getdate2" />

let suppose you have two date input you want to compare them.

so firstly write a common method to parse date.

 <script type="text/javascript">
            function parseDate(input) {
             var datecomp= input.split('.'); //if date format 21.09.2017

              var tparts=timecomp.split(':');//if time also giving
              return new Date(dparts[2], dparts[1]-1, dparts[0], tparts[0], tparts[1]);
// here new date(  year, month, date,)
            }
        </script>

parseDate() is the make common method for parsing the date. now you can checks your date =, > ,< any type of compare

    <script type="text/javascript">

              $(document).ready(function(){
              //parseDate(pass in this method date);
                    Var Date1=parseDate($("#getdate1").val());
                        Var Date2=parseDate($("#getdate2").val());
               //use any oe < or > or = as per ur requirment 
               if(Date1 = Date2){
         return false;  //or your code {}
}
 });
    </script>

For Sure this code will help you.

I guess this may work, in Eclipse select your project ? then click on project menu bar on top ? goto to properties ? click on Targeted Runtimes ? now you must select a check box next to the server you are using to run current project ? click Apply ? then click OK button. That's it, give a try.

If the data type of the field is date or timestamp, Oracle should always give the correct result if you add the correct number given in number of days (or a the correct fraction of a day in your case). So if you are trying to bump the value in 30 minutes, you should use :

select field + 0.5/24 from table;

Based on the information you provided, I believe this is what you tried to do and I am quite sure it works.

BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize=2; //try to decrease decoded image 
Bitmap bitmap=BitmapFactory.decodeStream(is, null, options); 
bitmap.compress(Bitmap.CompressFormat.JPEG, 70, fos); //compressed bitmap to file 

Of course AJAX is the solution,

To perform an AJAX request (for easiness we can use jQuery library).

Step1.

Include jQuery library in your web page

a. you can download jQuery library from jquery.com and keep it locally.

b. or simply paste the following code,

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>

Step 2.

Call a javascript function on button click

<button type="button" onclick="foo()">Click Me</button>

Step 3.

and finally the function

 function foo () {
      $.ajax({
        url:"test.php", //the page containing php script
        type: "POST", //request type
        success:function(result){
         alert(result);
       }
     });
 }

it will make an AJAX request to test.php when ever you clicks the button and alert the response.

For example your code in test.php is,

<?php echo 'hello'; ?>

then it will alert "hello" when ever you clicks the button.

skipUntil() with last()

skipUntil : ignore emitted items until another observable has emitted

last: emit last value from a sequence (i.e. wait until it completes then emit)

Note that anything emitted from the observable passed to skipUntil will cancel the skipping, which is why we need to add last() - to wait for the stream to complete.

main$.skipUntil(sequence2$.pipe(last()))

Official: https://rxjs-dev.firebaseapp.com/api/operators/skipUntil

Possible issue: Note that last() by itself will error if nothing is emitted. The last() operator does have a default parameter but only when used in conjunction with a predicate. I think if this situation is a problem for you (if sequence2$ may complete without emitting) then one of these should work (currently untested):

main$.skipUntil(sequence2$.pipe(defaultIfEmpty(undefined), last()))
main$.skipUntil(sequence2$.pipe(last(), catchError(() => of(undefined))

Note that undefined is a valid item to be emitted, but could actually be any value. Also note that this is the pipe attached to sequence2$ and not the main$ pipe.

You can create a countdown timer using applet, below is the code,

   import java.awt.*;
   import java.awt.event.*;

   import javax.swing.Timer; // not java.util.Timer
   import java.text.NumberFormat;
   import java.net.*;

    * it optionally plays a sound and optionally moves the browser to a new page.
    * Place the mouse over the applet to pause the count; move it off to resume.
    * This class demonstrates most applet methods and features.

For the EnumToBooleanConverter answer: Instead of returning DependencyProperty.UnsetValue consider returning Binding.DoNothing for the case where the radio button IsChecked value becomes false. The former indicates a problem (and might show the user a red rectangle or similar validation indicators) while the latter just indicates that nothing should be done, which is what is wanted in that case.

Because setting the div's display style property to "" doesn't change anything in the CSS rule itself. That basically just creates an "empty," inline CSS rule, which has no effect beyond clearing the same property on that element.

You need to set it to something that has a value:

document.getElementById('mybox').style.display = "block";

What you're doing would work if you were replacing an inline style on the div, like this:

<div id="myBox" style="display: none;"></div>

document.getElementById('mybox').style.display = "";

You can actually write to a named pipe using its name, btw.

Open a command shell as Administrator to get around the default "Access is denied" error:

echo Hello > \\.\pipe\PipeName

try:

%matplotlib notebook

see jakevdp reply here

EDIT for JupyterLab users:

Follow the instructions to install jupyter-matplotlib

Then the magic command above is no longer needed, as in the example:

# Enabling the `widget` backend.
# This requires jupyter-matplotlib a.k.a. ipympl.
# ipympl can be install via pip or conda.
%matplotlib widget
# aka import ipympl

import matplotlib.pyplot as plt

plt.plot([0, 1, 2, 2])
plt.show()

Finally, note Maarten Breddels' reply; IMHO ipyvolume is indeed very impressive (and useful!).

This is a more accurate way to do it. It places decimals behind the seconds giving more precision.

$now = date('Y-m-d\TH:i:s.uP', time());

Notice the .uP.

Do you mean full calendar days, or groups of 24 hours?

For simply 24 hours, assuming you're using Python's datetime, then the timedelta object already has a days property:

days = (a - b).days

For calendar days, you'll need to round a down to the nearest day, and b up to the nearest day, getting rid of the partial day on either side:

roundedA = a.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
roundedB = b.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
days = (roundedA - roundedB).days

$("a.directions-link").attr("href", $("a.directions-link").attr("href")+"...your additions...");

Most of images with intrinsic dimensions, that is a natural size, like a jpeg image. If the specified size defines one of both the width and the height, the missing value is determined using the intrinsic ratio... - see MDN.

But that doesn't work as expected if the images that are being set as direct flex items with the current Flexible Box Layout Module Level 1, as far as I know.

See these discussions and bug reports might be related:

• Flexbugs #14 - Chrome/Flexbox Intrinsic Sizing not implemented correctly.
• Firefox Bug 972595 - Flex containers should use "flex-basis" instead of "width" for computing intrinsic widths of flex items
• Chromium Issue 249112 - In Flexbox, allow intrinsic aspect ratios to inform the main-size calculation.

As a workaround, you could wrap each <img> with a <div> or a <span>, or so.

4.5 Implied Minimum Size of Flex Items

To provide a more reasonable default minimum size for flex items, this specification introduces a new auto value as the initial value of the min-width and min-height properties defined in CSS 2.1.

Alternatively, you can use CSS table layout instead, which you'll get similar results as flexbox, it will work on more browsers, even for IE8.

You can also combine the two env_keep statements in Ahmed Aswani's answer into a single statement like this:

Defaults env_keep += "http_proxy https_proxy"

You should also consider specifying env_keep for only a single command like this:

Defaults!/bin/[your_command] env_keep += "http_proxy https_proxy"

Adding a 1px transparent border will trigger anti-aliasing

outline: 1px solid transparent;

Alternatively, add a 1px transparent box-shadow.

box-shadow: 0 0 1px rgba(255,255,255,0);

CREATE VIEW EmployeeWithManager AS 
SELECT e.[emp id], e.[emp name], m.[emp id], m.[emp name] 
FROM Employee e LEFT JOIN Employee m ON e.[emp mgr id] = m.[emp id]

This definition uses a left outer join which means that even employees whose manager ID is NULL, or whose manager has been deleted (if your application allows that) will be listed, with their manager's attributes returned as NULL.

If you used an inner join instead, only people who have managers would be listed.

You'll want to use either JavaScript or a server-side language like PHP, ASP...etc

(supposedly can be done with HTML <embed> tag, which makes sense, but I haven't used, since PHP...etc is so simple/common)

Javascript can work: Here's a link to someone doing something similar via javascript on stackoverflow: How do I load the contents of a text file into a javascript variable?

PHP (as example of server-side language) is the easiest way to go though:

<div><p><?php include('myFile.txt'); ?></p></div>

To use this (if you're unfamiliar with PHP), you can:

1) check if you have php on your server

2) change the file extension of your .html file to .php

3) paste the code from my PHP example somewhere in the body of your newly-renamed PHP file

I had this same problem. The session ID is sent in a cookie, but since the request is cross-domain, the browser's security settings will block the cookie from being sent.

Solution: Generate the session ID on the client (in the browser), use Javascript sessionStorage to store the session ID then send the session ID with each request to the server.

I struggled a lot with this issue, and there weren't many good answers around. Here's an article detailing the solution: Javascript Cross-Domain Request With Session

With HTML5 you can use button[formaction]:

<form action="Edit">
  <button type="submit">Submit</button> <!-- Will post to default action "Edit" -->
  <button type="submit" formaction="Validate">Validate</button> <!-- Will override default action and post to "Validate -->
</form>

Convert.ToDecimal(the double you are trying to convert);

Your classes should look like this

[XmlRoot("StepList")]
public class StepList
{
    [XmlElement("Step")]
    public List<Step> Steps { get; set; }
}

public class Step
{
    [XmlElement("Name")]
    public string Name { get; set; }
    [XmlElement("Desc")]
    public string Desc { get; set; }
}

Here is my testcode.

string testData = @"<StepList>

                            <Desc>Desc1</Desc>

XmlSerializer serializer = new XmlSerializer(typeof(StepList));
using (TextReader reader = new StringReader(testData))
{
    StepList result = (StepList) serializer.Deserialize(reader);
}

If you want to read a text file you should load the file into a FileStream and deserialize this.

using (FileStream fileStream = new FileStream("<PathToYourFile>", FileMode.Open)) 
{
    StepList result = (StepList) serializer.Deserialize(fileStream);
}

Not my code, but a good example i think

using System.Data; 
using System.Data.SqlClient;

Use this Layout in your xml file

<LinearLayout
  android:id="@+id/contacts_type"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:visibility="gone">
</LinearLayout>

Define your layout in .class file

 LinearLayout linearLayout = (LinearLayout) findViewById(R.id.contacts_type);

Now if you want to display this layout just write

 linearLayout.setVisibility(View.VISIBLE);

and if you want to hide layout just write

 linearLayout.setVisibility(View.INVISIBLE);

You can use this code snippet:

var New1 = EmpList.OrderBy(z => z.Age).ToList();

where New1 is a List<Employee>.

EmpList is variable of a List<Employee>.

z is a variable of Employee type.

An asynchronously loaded script is likely going to run AFTER the document has been fully parsed and closed. Thus, you can't use document.write() from such a script (well technically you can, but it won't do what you want).

You will need to replace any document.write() statements in that script with explicit DOM manipulations by creating the DOM elements and then inserting them into a particular parent with .appendChild() or .insertBefore() or setting .innerHTML or some mechanism for direct DOM manipulation like that.

For example, instead of this type of code in an inline script:

<div id="container">
<script>
document.write('<span style="color:red;">Hello</span>');
</script>
</div>

You would use this to replace the inline script above in a dynamically loaded script:

var container = document.getElementById("container");
var content = document.createElement("span");
content.style.color = "red";
content.innerHTML = "Hello";
container.appendChild(content);

Or, if there was no other content in the container that you needed to just append to, you could simply do this:

var container = document.getElementById("container");
container.innerHTML = '<span style="color:red;">Hello</span>';

Just throw any RuntimeException from a method marked as @Transactional.

By default all RuntimeExceptions rollback transaction whereas checked exceptions don't. This is an EJB legacy. You can configure this by using rollbackFor() and noRollbackFor() annotation parameters:

@Transactional(rollbackFor=Exception.class)

This will rollback transaction after throwing any exception.

This will surely work:

UPDATE table1
SET table1.price=(SELECT table2.price
  FROM table2
  WHERE table2.id=table1.id AND table2.item=table1.item);

Assuming you want to get the value if the key does exist, use Dictionary<TKey, TValue>.TryGetValue:

int value;
if (dictionary.TryGetValue(key, out value))
{
    // Key was in dictionary; "value" contains corresponding value
} 
else 
{
    // Key wasn't in dictionary; "value" is now 0
}

(Using ContainsKey and then the the indexer makes it look the key up twice, which is pretty pointless.)

Note that even if you were using reference types, checking for null wouldn't work - the indexer for Dictionary<,> will throw an exception if you request a missing key, rather than returning null. (This is a big difference between Dictionary<,> and Hashtable.)
