The following method will remove all entries of a given value from an array without creating a new array and with only one iteration which is superfast. And it works in ancient Internet Explorer 5.5 browser:

function removeFromArray(arr, removeValue) {_x000D_
  for (var i = 0, k = 0, len = arr.length >>> 0; i < len; i++) {_x000D_
    if (k > 0)_x000D_
      arr[i - k] = arr[i];_x000D_
_x000D_
    if (arr[i] === removeValue)_x000D_
      k++;_x000D_
  }_x000D_
_x000D_
  for (; k--;)_x000D_
    arr.pop();_x000D_
}_x000D_
_x000D_
var a = [0, 1, 0, 2, 0, 3];_x000D_
_x000D_
document.getElementById('code').innerHTML =_x000D_
  'Initial array [' + a.join(', ') + ']';_x000D_

The manual for GNU Make gives a clear definition for all in its list of standard targets.

If the author of the Makefile is following that convention then the target all should:

1. Compile the entire program, but not build documentation.
2. Be the the default target. As in running just make should do the same as make all.

To achieve 1 all is typically defined as a .PHONY target that depends on the executable(s) that form the entire program:

.PHONY : all
all : executable

To achieve 2 all should either be the first target defined in the make file or be assigned as the default goal:

.DEFAULT_GOAL := all

I know this is has a lot of answers, but I needed to handle the following (which none of the answers seemed to fully support):

• Support of textarea with option to for multi-lines
• Decimals or negative numbers
• Max length per line
• Cross-browser support (Chrome, Edge, IE 11)
• Handling cut/paste operations and events

The solution allows me to define a textarea like this:

<textarea class="form-control" [(ngModel)]="this.myModelVariable"
    appOnlyNumbers [allowNegative]="true" [allowMultiLine]="true" 
    [allowDecimal]="true" [maxLength]="10"
    placeholder="Enter values (one per line)"></textarea>

Or if I just want positive integers

<textarea class="form-control" [(ngModel)]="this.myModelVariable"
    appOnlyNumbers [allowMultiLine]="true" [maxLength]="9"
    placeholder="Enter values (one per line)"></textarea>

Here is my directive:

import { Directive, HostListener, Input, ElementRef } from '@angular/core';

@Directive({
  selector: '[appOnlyNumbers]'
})
export class OnlyNumbersDirective {
  constructor(private el: ElementRef) { }

  @Input() allowMultiLine: boolean = false;
  @Input() allowNegative: boolean = false;
  @Input() allowDecimal: boolean = false;
  @Input() maxLength: number = 0;
  regex: RegExp;

  @HostListener('keypress', ['$event'])
  onKeyPress(event: KeyboardEvent) {
    this.validate(event, event.key === 'Enter' ? '\n' : event.key);
  }

  @HostListener('paste', ['$event'])
  onPaste(event: Event) {
    const pastedText = (<any>window).clipboardData && (<any>window).clipboardData.getData('Text') // If IE, use window
      || <ClipboardEvent>event && (<ClipboardEvent>event).clipboardData.getData('text/plain'); // Non-IE browsers
    this.validate(event, pastedText);
  }

  @HostListener('cut', ['$event'])
  onCut(event: Event) {
    this.validate(event, '');
  }

  validate(event: Event, text: string) {
    const txtInput = this.el.nativeElement;
    const newValue = (txtInput.value.substring(0, txtInput.selectionStart)
      + text + txtInput.value.substring(txtInput.selectionEnd));
    if (!this.regex) {
      this.regex = <RegExp>eval('/^'
        + (this.allowNegative ? '-?' : '')
        + (this.allowDecimal ? '((\\d+\\.?)|(\\.?))\\d*' : '\\d*')
        + '$/g');
    }
    var lines = this.allowMultiLine ? newValue.split('\n') : [newValue];
    for (let line of lines) {
      let lineText = line.replace('\r', '');
      if (this.maxLength && lineText.length > this.maxLength || !lineText.match(this.regex)) {
        event.preventDefault();
        return;
      }
    }
  }

}

Great answer by F.Mörk. But if you want to update translation, or add new languages once the application is released, you're stuck, because you always have to recompile it to generate the resources.dll.

Here is a solution to manually compile a resource dll. It uses the resgen.exe and al.exe tools (installed with the sdk).

Say you have a Strings.fr.resx resource file, you can compile a resources dll with the following batch:

resgen.exe /compile Strings.fr.resx,WpfRibbonApplication1.Strings.fr.resources 
Al.exe /t:lib /embed:WpfRibbonApplication1.Strings.fr.resources /culture:"fr" /out:"WpfRibbonApplication1.resources.dll"
del WpfRibbonApplication1.Strings.fr.resources
pause

Be sure to keep the original namespace in the file names (here "WpfRibbonApplication1")

player['score'] is your problem. player is apparently a list which means that there is no 'score' element. Instead you would do something like:

name, score = player[0], player[1]
return name + ' ' + str(score)

Of course, you would have to know the list indices (those are the 0 and 1 in my example).

Something like player['score'] is allowed in python, but player would have to be a dict.

You can read more about both lists and dicts in the python documentation.

A simple answer:

import java.io.File
import java.io.PrintWriter

def writeToFile(p: String, s: String): Unit = {
    val pw = new PrintWriter(new File(p))
    try pw.write(s) finally pw.close()
  }

Warning: Division by zero

The warning message 'Division by zero' is one of the most commonly asked questions among new PHP developers. This error will not cause an exception, therefore, some developers will occasionally suppress the warning by adding the error suppression operator @ before the expression. For example:

$value = @(2 / 0);

But, like with any warning, the best approach would be to track down the cause of the warning and resolve it. The cause of the warning is going to come from any instance where you attempt to divide by 0, a variable equal to 0, or a variable which has not been assigned (because NULL == 0) because the result will be 'undefined'.

To correct this warning, you should rewrite your expression to check that the value is not 0, if it is, do something else. If the value is zero you either should not divide, or you should change the value to 1 and then divide so the division results in the equivalent of having divided only by the additional variable.

if ( $var1 == 0 ) { // check if var1 equals zero
    $var1 = 1; // var1 equaled zero so change var1 to equal one instead
    $var3 = ($var2 / $var1); // divide var1/var2 ie. 1/1
} else {
    $var3 = ($var2 / $var1); // if var1 does not equal zero, divide
}

For dynamic pivot, use GROUP_CONCAT with CONCAT. The GROUP_CONCAT function concatenates strings from a group into one string with various options.

SET @sql = NULL;
SELECT
    GROUP_CONCAT(DISTINCT
    CONCAT(
      'SUM(CASE WHEN action = "',
      action,'"  AND ', 
           (CASE WHEN pagecount IS NOT NULL 
           THEN CONCAT("pagecount = ",pagecount) 
           ELSE pagecount IS NULL END),
      ' THEN 1 ELSE 0 end) AS ',
      action, IFNULL(pagecount,'')

    )
  )
INTO @sql
FROM
  t;

SET @sql = CONCAT('SELECT company_name, ', @sql, ' 
                  FROM t 
                   GROUP BY company_name');

PREPARE stmt FROM @sql;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

In bootstrap you can use .text-centerto align center. also add .row and .col-md-* to your code.

align= is deprecated,

Added .col-xs-* for demo

In IntelliJ Do as they say in eclipse "If you're facing this problem with Eclipse, I've been following many different solutions but the one that worked for me is this:

Right click your project folder and open up Properties.

From the right panel, select Java Build Path then go to Libraries tab.

Select Add External JARs to import the mysql driver.

From the right panel, select Deployment Assembly.

Select Add..., then select Java Build Path Entries and click Next.

You should see the sql driver on the list. Select it and click first.

And that's it! Try to run it again! Cheers!"

Here we have to add the jar file in Project Structure -> Libraries -> +(add)

For data import scripts, to replace "IF NOT EXISTS", in a way, there's a slightly awkward formulation that nevertheless works:

DO
$do$
BEGIN
PERFORM id
FROM whatever_table;

IF NOT FOUND THEN
-- INSERT stuff
END IF;
END
$do$;

Actually, for some rare case you could store app.config in class libraries (by adding manually) and parse it by OpenExeConfiguration.

 var fileMap =
    new ExeConfigurationFileMap {ExeConfigFilename = 
    @"C:\..somePath..\someName.config"};
 System.Configuration.Configuration config =
    ConfigurationManager.OpenMappedExeConfiguration(fileMap, 
    ConfigurationUserLevel.None);

You should really estimate the real need of this. For abstract data its not the best solution, but "Config Sections" could be very usefull!!

For example, we organised our N-Tier WCF architecture decoupled, without any metadata, simply by using Unity Container and Injection Factory based on Channel Factory T. We added externall ClassLibrary dll with just [Service Contract] Interfaces and common app.config in order to read endpoints from clientsection, and easily add/change them at one place.

I know there isn't any need to add a plugin for this.

But this can be useful if you are doing so many things with numbers. So checkout this plugin at least for a knowledge point of view.

By default xampp php log file path is in /xampp_installation_folder/php/logs/php_error_log, but I noticed that sometimes it would not be generated automatically. Maybe it could be a Windows account write permission problem? I am not sure, but I created the logs folder and php_error_log file manually and then php logs were logged in it finally.

TL;DR ...and late to the party, but that short explanation might help future googlers..

In general that error message means that the replacement doesn't fit into the corresponding column of the dataframe.

A minimal example:

df <- data.frame(a = 1:2); df$a <- 1:3

throws the error

Error in $<-.data.frame(*tmp*, a, value = 1:3) : replacement has 3 rows, data has 2

which is clear, because the vector a of df has 2 entries (rows) whilst the vector we try to replace it has 3 entries (rows).

You can do this a few ways. One, simply add this meta tag to your head:

<meta http-equiv="Cache-control" content="no-cache">

If you want to remove the document from cache, expires meta tag should work to delete it by setting its content attribute to -1 like so:

<meta http-equiv="Expires" content="-1">

http://www.metatags.org/meta_http_equiv_cache_control

Also, IE should give you the latest content for the main page. If you are having issues with external documents, like CSS and JS, add a dummy param at the end of your URLs with the current time in milliseconds so that it's never the same. This way IE, and other browsers, will always serve you the latest version. Here is an example:

<script src="mysite.com/js/myscript.js?12345">

UPDATE 1

After reading the comments I realize you wanted to programmatically erase the cache and not every time. What you could do is have a function in JS like:

eraseCache(){
  window.location = window.location.href+'?eraseCache=true';
}

Then, in PHP let's say, you do something like this:

<head>
<?php
    if (isset($_GET['eraseCache'])) {
        echo '<meta http-equiv="Cache-control" content="no-cache">';
        echo '<meta http-equiv="Expires" content="-1">';
        $cache = '?' . time();
    }
?>
<!-- ... other head HTML -->
<script src="mysite.com/js/script.js<?= $cache ?>"
</head>

This isn't tested, but should work. Basically, your JS function, if invoked, will reload the page, but adds a GET param to the end of the URL. Your site would then have some back-end code that looks for this param. If it exists, it adds the meta tags and a cache variable that contains a timestamp and appends it to the scripts and CSS that you are having caching issues with.

UPDATE 2

The meta tag indeed won't erase the cache on page load. So, technically you would need to run the eraseCache function in JS, once the page loads, you would need to load it again for the changes to take place. You should be able to fix this with your server side language. You could run the same eraseCache JS function, but instead of adding the meta tags, you need to add HTTP Cache headers:

<?php
    header("Cache-Control: no-cache, must-revalidate");
    header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
?>
<!-- Here you'd start your page... -->

This method works immediately without the need for page reload because it erases the cache before the page loads and also before anything is run.

Disable pointer events in the first line of your callback, and then resume them on the last line.

element.on('click', function() {
  element.css('pointer-events', 'none'); 
  //do all of your stuff
  element.css('pointer-events', 'auto');   
};

Add this to activity's xml in layout folder:

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">
    <android.support.v7.widget.Toolbar
        android:id="@+id/prod_toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>

Make toolbar clickable, add these to onCreate method:

Toolbar toolbar = (Toolbar) findViewById(R.id.prod_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        finish();
    }
});

You have to define void swapCase before the main definition.

mkdir vs mkdirs

If you want to create a single directory use mkdir

new File("/path/directory").mkdir();

If you want to create a hierarchy of folder structure use mkdirs

 new File("/path/directory").mkdirs();

from bs4 import BeautifulSoup
from selenium import webdriver

driver = webdriver.Chrome()
html_source_code = driver.execute_script("return document.body.innerHTML;")
html_soup: BeautifulSoup = BeautifulSoup(html_source_code, 'html.parser')

Now you can apply BeautifulSoup function to extract data...

You could also do something as follow

public enum DAY {MON, TUES, WED, THU, FRI, SAT, SUN};
EnumSet.allOf(DAY.class).stream().map(e -> e.name()).collect(Collectors.toList())

or

EnumSet.allOf(DAY.class).stream().map(DAY::name).collect(Collectors.toList())

The main reason why I stumbled across this question is that I wanted to write a generic validator that validates whether a given string enum name is valid for a given enum type (Sharing in case anyone finds useful).

For the validation, I had to use Apache's EnumUtils library since the type of enum is not known at compile time.

@SuppressWarnings({ "unchecked", "rawtypes" })
public static void isValidEnumsValid(Class clazz, Set<String> enumNames) {
    Set<String> notAllowedNames = enumNames.stream()
            .filter(enumName -> !EnumUtils.isValidEnum(clazz, enumName))
            .collect(Collectors.toSet());

    if (notAllowedNames.size() > 0) {
        String validEnumNames = (String) EnumUtils.getEnumMap(clazz).keySet().stream()
            .collect(Collectors.joining(", "));

        throw new IllegalArgumentException("The requested values '" + notAllowedNames.stream()
                .collect(Collectors.joining(",")) + "' are not valid. Please select one more (case-sensitive) "
                + "of the following : " + validEnumNames);
    }
}

I was too lazy to write an enum annotation validator as shown in here https://stackoverflow.com/a/51109419/1225551

I have faced the same parse sdk loading problem during eclipse startup like yours (Shown in image below)

The solution to above problem is to just delete(uninstall) the package Android Wear ARM EABI v7a system image available under Android 5.1.1 (API 22) if it's installed. (No need to uninstall whole 5.1.1 package). May be there is some eclipse bug with this package.

Finally restart eclipse to see your changes.

Edit: If the problem still exists, try removing other Android Wear package also (i.e Android Wear Intel x86 Atom System Image) as suggested by @Abhishek in comments below.

Can i suggest http://www.jqueryscript.net/form/Twitter-Like-Mentions-Auto-Suggesting-Plugin-with-jQuery-Bootstrap-Suggest.html, works more like the twitter post suggestion where it gives you a list of users or topics based on @ or # tags,

view demo here: http://www.jqueryscript.net/demo/Twitter-Like-Mentions-Auto-Suggesting-Plugin-with-jQuery-Bootstrap-Suggest/

in this one you can easily change the @ and # to anything you want

To submit a single file, you can simply use the File object from the input's .files array directly as the value of body: in your fetch() initializer:

const myInput = document.getElementById('my-input');

// Later, perhaps in a form 'submit' handler or the input's 'change' handler:
fetch('https://example.com/some_endpoint', {
  method: 'POST',
  body: myInput.files[0],
});

This works because File inherits from Blob, and Blob is one of the permissible BodyInit types defined in the Fetch Standard.

A simple possibility (if you'd rather avoid REs) is

' '.join(mystring.split())

The split and join perform the task you're explicitly asking about -- plus, they also do the extra one that you don't talk about but is seen in your example, removing trailing spaces;-).

If you have several fields in your table and your table is huge, it's better DO NOT USE * because of it load all fields to memory and using the following will have better performance

SELECT COUNT(1) FROM fooTable;

As Chris suggests, you can do it like this:

public string GetXMLAsString(XmlDocument myxml)
{
    return myxml.OuterXml;
}

Or like this:

public string GetXMLAsString(XmlDocument myxml)
    {

        StringWriter sw = new StringWriter();
        XmlTextWriter tx = new XmlTextWriter(sw);
        myxml.WriteTo(tx);

        string str = sw.ToString();// 
        return str;
    }

and if you really want to create a new XmlDocument then do this

XmlDocument newxmlDoc= myxml

I think this simply demonstrates what you are trying to achieve:

# coding: utf-8

class Class():
    count = 0
    names = []

    def __init__(self,name):
        self.number = Class.count
        self.name = name
        Class.count += 1
        Class.names.append(name)

l=[]
l.append(Class("uno"))
l.append(Class("duo"))
print l
print l[0].number, l[0].name
print l[1].number, l[1].name
print Class.count, Class.names

Run the code above and you get:-

[<__main__.Class instance at 0x6311b2c>, 
<__main__.Class instance at 0x63117ec>]
0 uno
1 duo
2 ['uno', 'duo']

I would opt for NOT EXISTS in this case.

SELECT D1.ShortCode
FROM Domain1 D1
WHERE NOT EXISTS
    (SELECT 'X'
     FROM Domain2 D2
     WHERE D2.ShortCode = D1.ShortCode
    )

It works in Kotlin after buildDrawingCache() being deprecated

 // convert imageView to bitmap
val bitmap = (imageViewId.getDrawable() as BitmapDrawable).getBitmap()

This isn't an answer, sadly. After running into the intermittent error for some time and finally being annoyed enough to try to fix it, I have yet to find a fix. I have, however, determined a recipe for reproducing my problem, which might help others.

In my case it is SOLELY a localhost problem, on my dev machine that also has the app's DB. It's a .NET 2.0 app I'm editing with VS2005. The Win7 64 bit machine also has VS2008 and .NET 3.5 installed.

Here's what will generate the error, from a variety of forms:

1. Load a fresh copy of the form.
2. Enter some data, and/or postback with any of the form's controls. As long as there is no significant delay, repeat all you like, and no errors occur.
3. Wait a little while (1 or 2 minutes maybe, not more than 5), and try another postback.

A minute or two delay "waiting for localhost" and then "Connection was reset" by the browser, and global.asax's application error trap logs:

Application_Error event: Invalid length for a Base-64 char array.
Stack Trace:
     at System.Convert.FromBase64String(String s)
     at System.Web.UI.ObjectStateFormatter.Deserialize(String inputString)
     at System.Web.UI.Util.DeserializeWithAssert(IStateFormatter formatter, String serializedState)
     at System.Web.UI.HiddenFieldPageStatePersister.Load()

In this case, it is not the SIZE of the viewstate, but something to do with page and/or viewstate caching that seems to be biting me. Setting <pages> parameters enableEventValidation="false", and viewStateEncryption="Never" in the Web.config did not change the behavior. Neither did setting the maxPageStateFieldLength to something modest.

What you are doing is printing the value in the array at spot [3][3], which is invalid for a 3by3 array, you need to loop over all the spots and print them.

for(int i = 0; i < 3; i++) {
    for(int j = 0; j < 3; j++) {
        printf("%d ", array[i][j]);
    }
    printf("\n");
} 

This will print it in the following format

10 23 42
1 654 0
40652 22 0

if you want more exact formatting you'll have to change how the printf is formatted.

It is called an interface. Many OO languages have this feature. You might want to read through the php explanation here: http://de2.php.net/interface

I would do something like this:

$.each(temp,function(key, value) 
{
    $select.append('<option value=' + key + '>' + value + '</option>');
});

JSON structure would be appreciated. At first you can experiment with find('element') - it depends on JSON.

Sometimes something strange happens and using Visual Studio to automatically restore doesn't work. In that case you can use the NuGet Package Manager Console. That is opened within Visual Studio from Tools -> NuGet Package Manager -> Package Manager Console. The commands within the console are simple. And to get context help while typing a command just press the button and it will give you all options that start with the letters you're typing. So if a package isn't installed, for example log4net, type the following command:

Install-Package log4net

You can do a whole lot more, like specify the version to install, update a package, uninstall a package, etc.

I had to use the console to help me when Visual Studio was acting like a weirdo.

First you have to add the eventlistener

google.maps.event.addListener(map, 'click', find_closest_marker);

Then create a function that loops through the array of markers and uses the haversine formula to calculate the distance of each marker from the click.

function rad(x) {return x*Math.PI/180;}
function find_closest_marker( event ) {
    var lat = event.latLng.lat();
    var lng = event.latLng.lng();
    var R = 6371; // radius of earth in km
    var distances = [];
    var closest = -1;
    for( i=0;i<map.markers.length; i++ ) {
        var mlat = map.markers[i].position.lat();
        var mlng = map.markers[i].position.lng();
        var dLat  = rad(mlat - lat);
        var dLong = rad(mlng - lng);
        var a = Math.sin(dLat/2) * Math.sin(dLat/2) +
            Math.cos(rad(lat)) * Math.cos(rad(lat)) * Math.sin(dLong/2) * Math.sin(dLong/2);
        var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
        var d = R * c;
        distances[i] = d;
        if ( closest == -1 || d < distances[closest] ) {
            closest = i;
        }
    }

    alert(map.markers[closest].title);
}

This keeps track of the closest markers and alerts its title.

I have my markers as an array on my map object

Threaded stoppable function

Instead of subclassing threading.Thread, one can modify the function to allow stopping by a flag.

We need an object, accessible to running function, to which we set the flag to stop running.

We can use threading.currentThread() object.

import threading
import time


def doit(arg):
    t = threading.currentThread()
    while getattr(t, "do_run", True):
        print ("working on %s" % arg)
        time.sleep(1)
    print("Stopping as you wish.")


def main():
    t = threading.Thread(target=doit, args=("task",))
    t.start()
    time.sleep(5)
    t.do_run = False
    t.join()

if __name__ == "__main__":
    main()

The trick is, that the running thread can have attached additional properties. The solution builds on assumptions:

• the thread has a property "do_run" with default value True
• driving parent process can assign to started thread the property "do_run" to False.

Running the code, we get following output:

$ python stopthread.py                                                        
working on task
working on task
working on task
working on task
working on task
Stopping as you wish.

Pill to kill - using Event

Other alternative is to use threading.Event as function argument. It is by default False, but external process can "set it" (to True) and function can learn about it using wait(timeout) function.

We can wait with zero timeout, but we can also use it as the sleeping timer (used below).

def doit(stop_event, arg):
    while not stop_event.wait(1):
        print ("working on %s" % arg)
    print("Stopping as you wish.")


def main():
    pill2kill = threading.Event()
    t = threading.Thread(target=doit, args=(pill2kill, "task"))
    t.start()
    time.sleep(5)
    pill2kill.set()
    t.join()

Edit: I tried this in Python 3.6. stop_event.wait() blocks the event (and so the while loop) until release. It does not return a boolean value. Using stop_event.is_set() works instead.

Stopping multiple threads with one pill

Advantage of pill to kill is better seen, if we have to stop multiple threads at once, as one pill will work for all.

The doit will not change at all, only the main handles the threads a bit differently.

def main():
    pill2kill = threading.Event()
    tasks = ["task ONE", "task TWO", "task THREE"]

    def thread_gen(pill2kill, tasks):
        for task in tasks:
            t = threading.Thread(target=doit, args=(pill2kill, task))
            yield t

    threads = list(thread_gen(pill2kill, tasks))
    for thread in threads:
        thread.start()
    time.sleep(5)
    pill2kill.set()
    for thread in threads:
        thread.join()

This code

var title = news.title;
var link = news.link;
arr.push({title : link});

is not doing what you think it does. What gets pushed is a new object with a single member named "title" and with link as the value ... the actual title value is not used. To save an object with two fields you have to do something like

arr.push({title:title, link:link});

or with recent Javascript advances you can use the shortcut

arr.push({title, link}); // Note: comma "," and not colon ":"

If instead you want the key of the object to be the content of the variable title you can use

arr.push({[title]: link}); // Note that title has been wrapped in brackets

mysqli_real_escape_string function requires the connection to your database.

$username = mysqli_real_escape_string($your_connection, $_POST['username']);

P.S.: Do not mix mysql_ functions* and mysqli_ functions*. Please use mysqli_* functions or PDO because mysql_* functions are deprecated and will be removed in the future.

Try like this...

Update t1.Column1 = value 
from tbltemp as t1 
inner join tblUser as t2 on t2.ID = t1.UserID 
where t1.[column1]=value and t2.[Column1] = value;

Inline javascript

<a href='index.html' 
    onmouseover='this.style.textDecoration="none"' 
    onmouseout='this.style.textDecoration="underline"'>
    Click Me
</a>

In a working draft of the CSS2 spec it was declared that you could use pseudo-classes inline like this:

<a href="http://www.w3.org/Style/CSS"
   style="{color: blue; background: white}  /* a+=0 b+=0 c+=0 */
      :visited {color: green}           /* a+=0 b+=1 c+=0 */
      :hover {background: yellow}       /* a+=0 b+=1 c+=0 */
      :visited:hover {color: purple}    /* a+=0 b+=2 c+=0 */
     ">
</a>

but it was never implemented in the release of the spec as far as I know.

http://www.w3.org/TR/2002/WD-css-style-attr-20020515#pseudo-rules

In management studio you can just right click to table and click to 'View Dependencies'

than you can see a list of Objects that have dependencies with your table :

Shortest Code

[x for _,x in sorted(zip(Y,X))]

Example:

X = ["a", "b", "c", "d", "e", "f", "g", "h", "i"]
Y = [ 0,   1,   1,    0,   1,   2,   2,   0,   1]

Z = [x for _,x in sorted(zip(Y,X))]
print(Z)  # ["a", "d", "h", "b", "c", "e", "i", "f", "g"]

Generally Speaking

[x for _, x in sorted(zip(Y,X), key=lambda pair: pair[0])]

Explained:

1. zip the two lists.
2. create a new, sorted list based on the zip using sorted().
3. using a list comprehension extract the first elements of each pair from the sorted, zipped list.

For more information on how to set\use the key parameter as well as the sorted function in general, take a look at this.

TLDR: simple defined variables (without var, let, const) could be deleted with delete. If you use var, let, const - they could not be deleted neither with delete nor with Reflect.deleteProperty.

delete simpleVar;
true

FF Nightly 53.0a1 shows same behaviour.

Fiddle: http://jsfiddle.net/uenrX/1/

The opacity property of the outer DIV cannot be undone by the inner DIV. If you want to achieve transparency, use rgba or hsla:

Outer div:

background-color: rgba(255, 255, 255, 0.9); /* Color white with alpha 0.9*/

Inner div:

background-color: #FFF; /* Background white, to override the background propery*/

EDIT
Because you've added filter:alpha(opacity=90) to your question, I assume that you also want a working solution for (older versions of) IE. This should work (-ms- prefix for the newest versions of IE):

/*Padded for readability, you can write the following at one line:*/
filter: progid:DXImageTransform.Microsoft.Gradient(
    GradientType=1,
    startColorStr="#E6FFFFFF",
    endColorStr="#E6FFFFFF");

/*Similarly: */
filter: progid:DXImageTransform.Microsoft.Gradient(
    GradientType=1,
    startColorStr="#E6FFFFFF",
    endColorStr="#E6FFFFFF");

I've used the Gradient filter, starting with the same start- and end-color, so that the background doesn't show a gradient, but a flat colour. The colour format is in the ARGB hex format. I've written a JavaScript snippet to convert relative opacity values to absolute alpha-hex values:

var opacity = .9;
var A_ofARGB = Math.round(opacity * 255).toString(16);
if(A_ofARGB.length == 1) A_ofARGB = "0"+a_ofARGB;
else if(!A_ofARGB.length) A_ofARGB = "00";
alert(A_ofARGB);

To get the bottom 1000 you will want to order it by a column in descending order, and still take the top 1000.

SELECT TOP 1000 *
FROM [SomeTable]
ORDER BY MySortColumn DESC

If you care for it to be in the same order as before you can use a common table expression for that:

;WITH CTE AS (
    SELECT TOP 1000 *
    FROM [SomeTable]
    ORDER BY MySortColumn DESC
)

SELECT * 
FROM CTE
ORDER BY MySortColumn

If you know what class the field is on you can access it using reflection. This example (it's in Groovy but the method calls are identical) gets a Field object for the class Foo and gets its value for the object b. It shows that you don't have to care about the exact concrete class of the object, what matters is that you know the class the field is on and that that class is either the concrete class or a superclass of the object.

groovy:000> class Foo { def stuff = "asdf"}
===> true
groovy:000> class Bar extends Foo {}
===> true
groovy:000> b = new Bar()
===> Bar@1f2be27
groovy:000> f = Foo.class.getDeclaredField('stuff')
===> private java.lang.Object Foo.stuff
groovy:000> f.getClass()
===> class java.lang.reflect.Field
groovy:000> f.setAccessible(true)
===> null
groovy:000> f.get(b)
===> asdf

You want to create an empty list, then append the created list to it. This will give you the list of lists. Example:

>>> l = []
>>> l.append([1,2,3])
>>> l.append([4,5,6])
>>> l
[[1, 2, 3], [4, 5, 6]]

function ConfirmDelete()
{
  var x = confirm("Are you sure you want to delete?");
  if (x)
      return true;
  else
    return false;
}


<input type="button" onclick="ConfirmDelete()">

Why are you combining GET and POST? Use one or the other.

$.ajax({
    type: 'post',
    data: {
        timestamp: timestamp,
        uid: uid
        ...
    }
});

php:

$uid =$_POST['uid'];

Or, just format your request properly (you're missing the ampersands for the get parameters).

url:"getdata.php?timestamp="+timestamp+"&uid="+id+"&uname="+name,

You can use .resize() to get every time the width/height actually changes, like this:

$(window).resize(function() {
  //resize just happened, pixels changed
});

You can view a working demo here, it takes the new height/width values and updates them in the page for you to see. Remember the event doesn't really start or end, it just "happens" when a resize occurs...there's nothing to say another one won't happen.

Edit: By comments it seems you want something like a "on-end" event, the solution you found does this, with a few exceptions (you can't distinguish between a mouse-up and a pause in a cross-browser way, the same for an end vs a pause). You can create that event though, to make it a bit cleaner, like this:

$(window).resize(function() {
    if(this.resizeTO) clearTimeout(this.resizeTO);
    this.resizeTO = setTimeout(function() {
        $(this).trigger('resizeEnd');
    }, 500);
});

You could have this is a base file somewhere, whatever you want to do...then you can bind to that new resizeEnd event you're triggering, like this:

$(window).bind('resizeEnd', function() {
    //do something, window hasn't changed size in 500ms
});

You can see a working demo of this approach here ?

If you want to set environment variables permanently in Git-Bash, you have two options:

1. Set a regular Windows environment variable. Git-bash gets all existing Windows environment variables at startupp.

2. Set up env variables in .bash_profile file.

.bash_profile is by default located in a user home folder, like C:\users\userName\git-home\.bash_profile. You can change the path to the bash home folder by setting HOME Windows environment variable.

.bash_profile file uses the regular Bash syntax and commands

# Export a variable in .bash_profile
export DIR=c:\dir
# Nix path style works too
export DIR=/c/dir

# And don't forget to add quotes if a variable contains whitespaces
export ANOTHER_DIR="c:\some dir"

Here is the detailed explanation of why "Random.nextInt(n) is both more efficient and less biased than Math.random() * n" from the Sun forums post that Gili linked to:

Math.random() uses Random.nextDouble() internally.

Random.nextDouble() uses Random.next() twice to generate a double that has approximately uniformly distributed bits in its mantissa, so it is uniformly distributed in the range 0 to 1-(2^-53).

Random.nextInt(n) uses Random.next() less than twice on average- it uses it once, and if the value obtained is above the highest multiple of n below MAX_INT it tries again, otherwise is returns the value modulo n (this prevents the values above the highest multiple of n below MAX_INT skewing the distribution), so returning a value which is uniformly distributed in the range 0 to n-1.

Prior to scaling by 6, the output of Math.random() is one of 2^53 possible values drawn from a uniform distribution.

Scaling by 6 doesn't alter the number of possible values, and casting to an int then forces these values into one of six 'buckets' (0, 1, 2, 3, 4, 5), each bucket corresponding to ranges encompassing either 1501199875790165 or 1501199875790166 of the possible values (as 6 is not a disvisor of 2^53). This means that for a sufficient number of dice rolls (or a die with a sufficiently large number of sides), the die will show itself to be biased towards the larger buckets.

You will be waiting a very long time rolling dice for this effect to show up.

Math.random() also requires about twice the processing and is subject to synchronization.

You can try this force-download script. Even if you don't use it, it'll probably point you in the right direction:

<?php

if(ini_get('zlib.output_compression'))
  ini_set('zlib.output_compression', 'Off');

  exit;
} elseif ( ! file_exists( $filename ) ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: File not found. USE force-download.php?file=filepath</body></html>";

exit();

Well, it depends. If the byte-code is translated into machine-code (and not just JIT) (I mean if you execute the program) and if your program uses many allocations/deallocations it could be faster because the GC algorithm just need one pass (theoretically) through the whole memory once, but normal malloc/realloc/free C/C++ calls causes an overhead on every call (call-overhead, data-structure overhead, cache misses ;) ).

So it is theoretically possible (also for other GC languages).

I don't really see the extreme disadvantage of not to be able to use metaprogramming with C# for the most applications, because the most programmers don't use it anyway.

Another big advantage is that the SQL, like the LINQ "extension", provides opportunities for the compiler to optimize calls to databases (in other words, the compiler could compile the whole LINQ to one "blob" binary where the called functions are inlined or for your use optimized, but I'm speculating here).

Best way is running Particular migration again by using down or up(in rails 4. It's change)

rails db:migrate:up VERSION=timestamp

Now how you get the timestamp. Go to this path

/db/migrate

Identify migration file you want to revert.pick the timestamp from that file name.

I prefer, and use, your #1 option. I don't like #2 because to me View() implies you are returning an entire page. It should be a fully fleshed out and valid HTML page once the view engine is done with it. PartialView() was created to return arbitrary chunks of HTML.

I don't think it's a big deal to have a view that just calls a partial. It's still DRY, and allows you to use the logic of the partial in two scenarios.

Many people dislike fragmenting their action's call paths with Request.IsAjaxRequest(), and I can appreciate that. But IMO, if all you are doing is deciding whether to call View() or PartialView() then the branch is not a big deal and is easy to maintain (and test). If you find yourself using IsAjaxRequest() to determine large portions of how your action plays out, then making a separate AJAX action is probably better.

Another way to rename the database or taking an image of the database is by using the reverse engineering option in the database tab. It will create an ER diagram for the database. Rename the schema there.

After that, go to the File menu and go to export and forward engineer the database.

Then you can import the database.

Try:

select v.*, row_number() over (partition by id order by elem) rn from
(select
    id,
    unnest(string_to_array(elements, ',')) AS elem
 from myTable) v

Lets look at some test cases - try running the following expressions in your JS console:

"a" < "b"

"aa" < "ab"

"aaa" < "aab"

All return true.

JavaScript compares strings character by character and "a" comes before "b" in the alphabet - hence less than.

In your case it works like so -

1 . "a?aaa" < "?a?b"

compares the first two "a" characters - all equal, lets move to the next character.

2 . "a?a??aa" < "a?b??"

compares the second characters "a" against "b" - whoop! "a" comes before "b". Returns true.

I've solved this issue with the optional parameter count set to -1.

Set border: 1px solid black to make all sides equals and remove any kind of custom border (other than solid). Also, set box-shadow: none to remove any inset shadow applied to it.

To build ontop of @tomloprod's answer. By the odd chance that you are using x-editable, and have a select2(v4) field and have multiple items you need to pre-select. You can use the following piece of code:

$("#select2field").on("shown", function(e, editable){
    $(["test1", "test2", "test3", "test4"]).each(function(k, v){
        // Create a DOM Option and pre-select by default~
        var newOption = new Option(v.text, v.id, true, true);
        // Append it to the select
        $(editable.input.$input).append(newOption).trigger('change');
     });
});

and here it is in action:

I guess that this would work even if you aren't using x-editable. I hope that htis could help someone.

If you want an efficient way with milliseconds:

var daysOfYear = [];
for (var d = begin; d <= end; d = d + 86400000) {
    daysOfYear.push(new Date(d));
}

The solution provided by "Tomas R" works perfect for the OP's question and it natively available.

Try: chkdsk c: > output.txt | type output.txt

The output is of this command involves a completion percentage that gets serially output to the file hence it will look a bit messy (i.e. the text will be appended as it progress). This does not happen to the bits that gets output to STDOUT (the screen). It is how it would be if you just do the same command without redirection.

    //sure run it i will also test it
//we make a class that extends with the fragment
    public class Example_3_1 extends Fragment  implements OnClickListener
    {
       View vi;
        EditText t;
        EditText t1;
        Button bu;
 // that are by defult function of fragment extend class
     @Override
       public View onCreateView(LayoutInflater inflater,ViewGroup container,BundlesavedInstanceState) 
       {        
           vi=inflater.inflate(R.layout.example_3_1, container, false);// load the xml file 
           bu=(Button) vi.findViewById(R.id.button1);// get button id from example_3_1 xml file
           bu.setOnClickListener(this); //on button appay click listner
           t=(EditText) vi.findViewById(R.id.editText1);// id get from example_3_1 xml file
           t1=(EditText) vi.findViewById(R.id.editText2);
          return vi; // return the view object,that set the xml file  example_3_1 xml file
       }
       @Override
       public void onClick(View v)//on button click that called
       {

          switch(v.getId())// on run time get id what button os click and get id
          {
          case R.id.button1:        // it mean if button1 click then this work
           t.setText("UMTien");     //set text 
           t1.setText("programming");
           break;
          }
    }     }

By selecting 'Class Library' you were accidentally telling it to make a .Net Library using the CLI (managed) extenstion of C++.

Instead, create a Win32 project, and in the Application Settings on the next page, choose 'DLL'.

You can also make an MFC DLL or ATL DLL from those library choices if you want to go that route, but it sounds like you don't.

You can use Environment.CurrentDirectory to get the current directory, and FileSystemInfo.FullPath to get the full path to any location. So, fully qualify both the current directory and the file in question, and then check whether the full file name starts with the directory name - if it does, just take the appropriate substring based on the directory name's length.

Here's some sample code:

using System;
using System.IO;

class Program
{
    public static void Main(string[] args)
    {
        string currentDir = Environment.CurrentDirectory;
        DirectoryInfo directory = new DirectoryInfo(currentDir);
        FileInfo file = new FileInfo(args[0]);

        string fullDirectory = directory.FullName;
        string fullFile = file.FullName;

        if (!fullFile.StartsWith(fullDirectory))
        {
            Console.WriteLine("Unable to make relative path");
        }
        else
        {
            // The +1 is to avoid the directory separator
            Console.WriteLine("Relative path: {0}",
                              fullFile.Substring(fullDirectory.Length+1));
        }
    }
}

I'm not saying it's the most robust thing in the world (symlinks could probably confuse it) but it's probably okay if this is just a tool you'll be using occasionally.

If you want to use C++ streams rather than C functions, you can do the following:

int ar[] = { 20, 30, 40, 50, 60, 70, 80, 90 };
const int siz_ar = sizeof(ar) / sizeof(int);

for (int i = 0; i < siz_ar; ++i)
    cout << ar[i] << " ";
cout << endl;

for (int i = 0; i < siz_ar; ++i)
    cout << hex << setfill('0') << setw(2) << ar[i] << " ";
cout << endl;

Very simple.

Output:

20 30 40 50 60 70 80 90
14 1e 28 32 3c 46 50 5a 

If you are using 32-bit ubuntu (my case) then it is most likely that Android Studio has downloaded 64-bit version of adb and fastboot inside your sdk/platform-tools folder. I think you already have installed adb (and fastboot). If you haven't then run these commands in terminal:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install android-tools-adb android-tools-fastboot

This will install 32-bit version of adb and fastboot. Now just replace the 64-bit adb and fastboot executable files in sdk/platform-tools with the installed 32-bit versions:

cp /usr/bin/adb <path-to-your-adt-sdk-package>/sdk/platform-tools/adb
cp /usr/bin/fastboot <path-to-your-adt-sdk-package>/sdk/platformtools/fastboot

Now your android studio should be able to run your App in your device.

Some context that I haven't seen clearly stated in the existing answers (and also a lot has changed since 2012!):

If you can control both the 3rd party iframe and the parent page (i.e. you are able to insert JavaScript on the parent page), then several workarounds are available. I would suggest the most elegant of these is making use of the postMessage API as described by @Frank's answer, as a) this does not require any redirects and b) does not require any user interactions.

If you do NOT control both the 3rd party iframe and the parent page, e.g. you have a widget hosted on a site you do not control, then most of the answers posted here will not work in Safari as of May 2020, and will stop working in Chrome around 2022. That is, unless a user has already visited your domain or interacts with the iframe, you are not able to set cookies. However, there are some commercial services offering solutions to solve this problem, such as CloudCookie.io

Well, I'm not sure if my solution is best practice. Using the NotificationBuilder my code looks like that:

private void showNotification() {
    Intent notificationIntent = new Intent(this, MainActivity.class);

    PendingIntent contentIntent = PendingIntent.getActivity(
                this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);
    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(NOTIFICATION_ID, builder.build());
    }

Manifest:

    <activity
        android:name=".MainActivity"
        android:launchMode="singleInstance"
    </activity>

and here the Service:

    <service
        android:name=".services.ProtectionService"
        android:launchMode="singleTask">
    </service>

I don't know if there really is a singleTask at Service but this works properly at my application...

Doing Project->Clean… in Eclipse solved this problem for me.

Verilog thinks in bits, so reg [7:0] a[0:3] will give you a 4x8 bit array (=4x1 byte array). You get the first byte out of this with a[0]. The third bit of the 2nd byte is a[1][2].

For a 2D array of bytes, first check your simulator/compiler. Older versions (pre '01, I believe) won't support this. Then reg [7:0] a [0:3] [0:3] will give you a 2D array of bytes. A single bit can be accessed with a[2][0][7] for example.

reg [7:0] a [0:3];
reg [7:0] b [0:3] [0:3];

reg [7:0] c;
reg d;

initial begin

   for (int i=0; i<=3; i++) begin
      a[i] = i[7:0];
   end

   c = a[0];
   d = a[1][2]; 


   // using 2D
   for (int i=0; i<=3; i++)
      for (int j=0; j<=3; j++)
          b[i][j] = i*j;  // watch this if you're building hardware

end

Try this regular expression:

^(.{0,2}|([^A]..|A[^B].|AB[^C])|.{4,})$

It describes three cases:

1. less than three arbitrary character
2. exactly three characters, while either
   • the first is not A, or
   • the first is A but the second is not B, or
   • the first is A, the second B but the third is not C
3. more than three arbitrary characters

This is a good way to create a component in vue.

let template = `<ul>
  <li>Your data here</li>
</ul>`;

Vue.component('my-task', {
  template: template,
  data() {

  },
  props: {
    task: {
      type: String
    }
  },
  methods: {

  },
  computed: {

  },
  ready() {

  }
});

new Vue({
 el : '#app'
});

Finding all possible paths is a hard problem, since there are exponential number of simple paths. Even finding the kth shortest path [or longest path] are NP-Hard.

One possible solution to find all paths [or all paths up to a certain length] from s to t is BFS, without keeping a visited set, or for the weighted version - you might want to use uniform cost search

Note that also in every graph which has cycles [it is not a DAG] there might be infinite number of paths between s to t.

For Converting an Image object to byte[] you can do as follows:

public static byte[] converterDemo(Image x)
{
    ImageConverter _imageConverter = new ImageConverter();
    byte[] xByte = (byte[])_imageConverter.ConvertTo(x, typeof(byte[]));
    return xByte;
}

Possible Duplicate Question

<@include> - The directive tag instructs the JSP compiler to merge contents of the included file into the JSP before creating the generated servlet code. It is the equivalent to cutting and pasting the text from your include page right into your JSP.

• Only one servlet is executed at run time.
• Scriptlet variables declared in the parent page can be accessed in the included page (remember, they are the same page).
• The included page does not need to able to be compiled as a standalone JSP. It can be a code fragment or plain text. The included page will never be compiled as a standalone. The included page can also have any extension, though .jspf has become a conventionally used extension.
• One drawback on older containers is that changes to the include pages may not take effect until the parent page is updated. Recent versions of Tomcat will check the include pages for updates and force a recompile of the parent if they're updated.
• A further drawback is that since the code is inlined directly into the service method of the generated servlet, the method can grow very large. If it exceeds 64 KB, your JSP compilation will likely fail.

<jsp:include> - The JSP Action tag on the other hand instructs the container to pause the execution of this page, go run the included page, and merge the output from that page into the output from this page.

• Each included page is executed as a separate servlet at run time.
• Pages can conditionally be included at run time. This is often useful for templating frameworks that build pages out of includes. The parent page can determine which page, if any, to include according to some run-time condition.
• The values of scriptlet variables need to be explicitly passed to the include page.
• The included page must be able to be run on its own.
• You are less likely to run into compilation errors due to the maximum method size being exceeded in the generated servlet class.

Depending on your needs, you may either use <@include> or <jsp:include>

Try:

SELECT MEMBSHIP_ID
  FROM user_payment
 WHERE user_id=1 
ORDER BY paym_date = (select MAX(paym_date) from user_payment and user_id=1);

Or:

SELECT MEMBSHIP_ID
FROM (
  SELECT MEMBSHIP_ID, row_number() over (order by paym_date desc) rn
      FROM user_payment
     WHERE user_id=1 )
WHERE rn = 1

The following (using four escapes) works in my environment: Mac, safari Version 10.0.3 (12602.4.8)

var myReg = new RegExp(‘\\\\b’+ variable + ‘\\\\b’, ‘g’)

In addition to DCookie's answer above, you can also use chr(39) for a single quote.

I find this particularly useful when I have to create a number of insert/update statements based on a large amount of existing data.

Here's a very quick example:

Lets say we have a very simple table, Customers, that has 2 columns, FirstName and LastName. We need to move the data into Customers2, so we need to generate a bunch of INSERT statements.

Select 'INSERT INTO Customers2 (FirstName, LastName) ' ||
       'VALUES (' || chr(39) || FirstName || chr(39) ',' || 
       chr(39) || LastName || chr(39) || ');' From Customers;

I've found this to be very useful when moving data from one environment to another, or when rebuilding an environment quickly.

After compiling my code in Android Studio, I found it here:

~\MyApp_Name\app\build\outputs\apk\app-debug.apk

You can use multiple id's the way you wrote:

$('#upload_link, #upload_link2, #upload_link3')

However, that doesn't mean that those ids exist within the DOM when you've executed your code. It also doesn't mean that upload is a legitimate function. It also doesn't mean that upload has been built in a way that allows for multiple elements in a selection.

upload is a custom jQuery plugin, so you'll have to show what's going on with upload for us to be able to help you.

Closed connection in another client

In my case, the error was:

java.net.SocketException: Software caused connection abort: recv failed

It was received in eclipse while debugging a java application accessing a H2 database. The source of the error was that I had initially opened the database with SQuirreL to check manually for integrity. I did use the flag to enable multiple connections to the same DB (i.e. AUTO_SERVER=TRUE), so there was no problem connecting to the DB from java.

The error appeared when, after a while --it is a long java process-- I decided to close SQuirreL to free resources. It appears as if SQuirreL were the one "owning" the DB server instance and that it was shut down with the SQuirreL connection.

Restarting the Java application did not yield the error again.

=== Common Saying (from months to years old) ===

If you just for common use, here is the code as your information:

DateTime today = DateTime.Today;
DateTime bday = DateTime.Parse("2016-2-14");
int age = today.Year - bday.Year;
var unit = "";

if (bday > today.AddYears(-age))
{
    age--;
}
if (age == 0)   // Under one year old
{
    age = today.Month - bday.Month;

    age = age <= 0 ? (12 + age) : age;  // The next year before birthday

    age = today.Day - bday.Day >= 0 ? age : --age;  // Before the birthday.day

    unit = "month";
}
else {
    unit = "year";
}

if (age > 1)
{
    unit = unit + "s";
}

The test result as below:

The birthday: 2016-2-14

2016-2-15 =>  age=0, unit=month;
2016-5-13 =>  age=2, unit=months;
2016-5-14 =>  age=3, unit=months; 
2016-6-13 =>  age=3, unit=months; 
2016-6-15 =>  age=4, unit=months; 
2017-1-13 =>  age=10, unit=months; 
2017-1-14 =>  age=11, unit=months; 
2017-2-13 =>  age=11, unit=months; 
2017-2-14 =>  age=1, unit=year; 
2017-2-15 =>  age=1, unit=year; 
2017-3-13 =>  age=1, unit=year;
2018-1-13 =>  age=1, unit=year; 
2018-1-14 =>  age=1, unit=year; 
2018-2-13 =>  age=1, unit=year; 
2018-2-14 =>  age=2, unit=years; 

You can call a stored procedure using SqlQuery (See here)

// Prepare the query
var query = context.Functions.SqlQuery(
    "EXEC [dbo].[GetFunctionByID] @p1", 
    new SqlParameter("p1", 200));

// add NoTracking() if required

// Fetch the results
var result = query.ToList();

l = [1, 2, 3, 4, 5]
del l[0:3] # Here 3 specifies the number of items to be deleted.

This is the code if you want to delete a number of items from the list. You might as well skip the zero before the colon. It does not have that importance. This might do as well.

l = [1, 2, 3, 4, 5]
del l[:3] # Here 3 specifies the number of items to be deleted.

If you end up with a SecurityException (and the call does not work), You should consider requesting the user permission to make a call as this is considered a dangerous permission:

ActivityCompat.requestPermissions(
    activity,
    new String[] {Manifest.permission.CALL_PHONE},
    1
);

Note this has nothing to do with the manifest permission (that you must have as well)

here's how you can do it with a cool shell trick:

mysql -uroot -p -hslavedb.mydomain.com mydb_production <<< 'select * from users'

'<<<' instructs the shell to take whatever follows it as stdin, similar to piping from echo.

use the -t flag to enable table-format output

You can't search LONGs directly. LONGs can't appear in the WHERE clause. They can appear in the SELECT list though so you can use that to narrow down the number of rows you'd have to examine.

Oracle has recommended converting LONGs to CLOBs for at least the past 2 releases. There are fewer restrictions on CLOBs.

This may be used in many other scenarios, where you need to copy only a portion of your original string to the destination. Using strncpy() you can copy a limited portion of the original string as opposed by strcpy(). I see the code you have put up comes from publib.boulder.ibm.com.

If you want to use a stable version of your preferred Laravel version of choice, use:

I have created a library based on Nouman Hanif's answer with some additions. For example, fixing a bug that caused an indirect infinite loop on View.invalidate() calls.

OTOH, the library also supports outlined text in EditText widgets, as it was my real goal and it needed a bit more work than TextView.

Here is the link to my library: https://github.com/biomorgoth/android-outline-textview

Thanks to Nouman Hanif for the initial idea on the solution!

Just call fig.tight_layout() as you normally would. (pyplot is just a convenience wrapper. In most cases, you only use it to quickly generate figure and axes objects and then call their methods directly.)

There shouldn't be a difference between the QtAgg backend and the default backend (or if there is, it's a bug).

E.g.

import matplotlib.pyplot as plt

#-- In your case, you'd do something more like:
# from matplotlib.figure import Figure
# fig = Figure()
#-- ...but we want to use it interactive for a quick example, so 
#--    we'll do it this way
fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

plt.show()

Before Tight Layout

After Tight Layout

import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=4, ncols=4)

for i, ax in enumerate(axes.flat, start=1):
    ax.set_title('Test Axes {}'.format(i))
    ax.set_xlabel('X axis')
    ax.set_ylabel('Y axis')

fig.tight_layout()

plt.show()

Came across SSIS package that schedule to run as sql job, you can identify where the SSIS package located by looking at the sql job properties; SQL job -> properties -> Steps (from select a page on left side) -> select job (from job list) -> edit -> job step properties shows up this got all the configuration for SSIS package, including its original path, in my case its under “MSDB”

Now connect to sql integration services; - open sql management studio - select server type to “integration services” - enter server name - you will see your SSIS package under “stored packages”

to edit the package right click and export to “file system” you’ll get file with extension .dtx it can be open in visual studio, I used the version visual studio 2012

There are two reasons you might get this message:

1. ASP.Net is not configured. For this run from Administrator command %FrameworkDir%\%FrameworkVersion%\aspnet_regiis -i. Read the message carefully. On Windows8/IIS8 it may say that this is no longer supported and you may have to use Turn Windows Features On/Off dialog in Install/Uninstall a Program in Control Panel.
2. Another reason this may happen is because your App Pool is not configured correctly. For example, you created website for WordPress and you also want to throw in few aspx files in there, WordPress creates app pool that says don't run CLR stuff. To fix this just open up App Pool and enable CLR.

Try this one liner bash command to backup all your apps:

for package in $(adb shell pm list packages -3 | tr -d '\r' | sed 's/package://g'); do apk=$(adb shell pm path $package | tr -d '\r' | sed 's/package://g'); echo "Pulling $apk"; adb pull -p $apk "$package".apk; done

This command is derived from Firelord's script. I just renamed all apks to their package names for solving the issue with elcuco's script, i.e the same base.apk file getting overwritten on Android 6.0 "Marshmallow" and above.

Note that this command backs up only 3rd party apps, coz I don't see the point of backing up built-in apps. But if you wanna backup system apps too, just omit the -3 option.

grep's -A 1 option will give you one line after; -B 1 will give you one line before; and -C 1 combines both to give you one line both before and after, -1 does the same.

For a .mp4 this works ( safari mobile & desktop ) :

<video height="250" width="250" controls>
    <source src="video.mp4" type="video/mp4" />
    Your browser does not support the video tag.
</video>

The controls=”true” mentioned in an above post make no sence to me as Apple says just use controls on its own.

Reference : “To use HTML5 audio or video, start by creating an  or  element, specifying a source URL for the media, and including the controls attribute. <video src="http://example.com/path/mymovie.mp4" controls></video>”

Source : https://developer.apple.com/library/content/documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/Introduction/Introduction.html

In my dealings ( a small digression ) : I have found that uploading video from iPhone sends it to server as .quicktime. Ironically, this is the problem when trying to play back the video from the server on safari. ( mobile & desktop ).

So if ( like me ) you are experiencing a .quicktime ( or anything other than .mp4 ) problem in safari, here is a work around provided by apple. Note, I'm yet to test it myself and I'm not all that happy with it at a glance, just providing more info.

Reference : “Fall Back to the QuickTime Plug-in There is a simple way to fall back to the QuickTime plug-in that works for nearly all browsers—download the prebuilt JavaScript file provided by Apple, ac_quicktime.js, from HTML Video Example and include it in your webpage by inserting the following line of code into your HTML head: <script src="ac_quicktime.js" type="text/javascript"></script>”

Source : https://developer.apple.com/library/content/documentation/AudioVideo/Conceptual/Using_HTML5_Audio_Video/AudioandVideoTagBasics/AudioandVideoTagBasics.html#//apple_ref/doc/uid/TP40009523-CH2-SW6

Update: For .quicktime rename to .mov prior upload to server ( in base64 filetype "data:video/mov;" ), skip ac_quicktime.js . . . will then work in html video tag; Hackerdy Hack.

In later versions (tested with TensorFlow 1.14) there's a more numpy-like way to get the shape of a tensor. You can use tensor.shape to get the shape of the tensor.

tensor_shape = tensor.shape
print(tensor_shape)

What he wants to say is:

"If you have two classes which share most of the same properties you can cast an object from class a to class b and automatically make the system understand the assignment via the shared property names?"

Option 1: Use reflection

Disadvantage : It's gonna slow you down more than you think.

Option 2: Make one class derive from another, the first one with common properties and other an extension of that.

Disadvantage: Coupled! if your're doing that for two layers in your application then the two layers will be coupled!

Let there be:

class customer
{
    public string firstname { get; set; }
    public string lastname { get; set; }
    public int age { get; set; }
}
class employee
{
    public string firstname { get; set; }
    public int age { get; set; } 
}

Now here is an extension for Object type:

public static T Cast<T>(this Object myobj)
{
    Type objectType = myobj.GetType();
    Type target = typeof(T);
    var x = Activator.CreateInstance(target, false);
    var z = from source in objectType.GetMembers().ToList()
        where source.MemberType == MemberTypes.Property select source ;
    var d = from source in target.GetMembers().ToList()
        where source.MemberType == MemberTypes.Property select source;
    List<MemberInfo> members = d.Where(memberInfo => d.Select(c => c.Name)
       .ToList().Contains(memberInfo.Name)).ToList();
    PropertyInfo propertyInfo;
    object value;
    foreach (var memberInfo in members)
    {
        propertyInfo = typeof(T).GetProperty(memberInfo.Name);
        value = myobj.GetType().GetProperty(memberInfo.Name).GetValue(myobj,null);

        propertyInfo.SetValue(x,value,null);
    }   
    return (T)x;
}  

Now you use it like this:

static void Main(string[] args)
{
    var cus = new customer();
    cus.firstname = "John";
    cus.age = 3;
    employee emp =  cus.Cast<employee>();
}

Method cast checks common properties between two objects and does the assignment automatically.

Please note, the way that build parameters are accessed inside pipeline scripts (pipeline plugin) has changed. This approach:

getBinding().hasVariable("MY_PARAM")

Is not working anymore. Please try this instead:

def myBool = env.getEnvironment().containsKey("MY_BOOL") ? Boolean.parseBoolean("$env.MY_BOOL") : false

As now Android Studio is stable, there is an easy way to do it.

1. Right click on your project file
2. Select "Open Module Settings"
3. Go to the "Flavors" tab.

4. Select the Min SDK Version from the drop down list

PS: Though this question was already answered but Android Studio has changed a little bit by its stable release. So an easy straight forward way will help any new answer seeker landing here.

I think it is a better idea to start working with a raw data and then translate it to DOM (document object model)

I would suggest you to work with array of objects and then output it to the DOM in order to accomplish your task.

You can see working example of following code at http://www.softxml.com/stackoverflow/shoppingCart.htm

You can try following approach:

//create array that will hold all ordered products
    var shoppingCart = [];

    //this function manipulates DOM and displays content of our shopping cart
    function displayShoppingCart(){
        var orderedProductsTblBody=document.getElementById("orderedProductsTblBody");
        //ensure we delete all previously added rows from ordered products table
        while(orderedProductsTblBody.rows.length>0) {
            orderedProductsTblBody.deleteRow(0);
        }

        //variable to hold total price of shopping cart
        var cart_total_price=0;
        //iterate over array of objects
        for(var product in shoppingCart){
            //add new row      
            var row=orderedProductsTblBody.insertRow();
            //create three cells for product properties 
            var cellName = row.insertCell(0);
            var cellDescription = row.insertCell(1);
            var cellPrice = row.insertCell(2);
            cellPrice.align="right";
            //fill cells with values from current product object of our array
            cellName.innerHTML = shoppingCart[product].Name;
            cellDescription.innerHTML = shoppingCart[product].Description;
            cellPrice.innerHTML = shoppingCart[product].Price;
            cart_total_price+=shoppingCart[product].Price;
        }
        //fill total cost of our shopping cart 
        document.getElementById("cart_total").innerHTML=cart_total_price;
    }


    function AddtoCart(name,description,price){
       //Below we create JavaScript Object that will hold three properties you have mentioned:    Name,Description and Price
       var singleProduct = {};
       //Fill the product object with data
       singleProduct.Name=name;
       singleProduct.Description=description;
       singleProduct.Price=price;
       //Add newly created product to our shopping cart 
       shoppingCart.push(singleProduct);
       //call display function to show on screen
       displayShoppingCart();

    }  


    //Add some products to our shopping cart via code or you can create a button with onclick event
    //AddtoCart("Table","Big red table",50);
    //AddtoCart("Door","Big yellow door",150);
    //AddtoCart("Car","Ferrari S23",150000);

Please have a look at following free client-side shopping cart:

SoftEcart(js) is a Responsive, Handlebars & JSON based, E-Commerce shopping cart written in JavaScript with built-in PayPal integration.

Documentation

http://www.softxml.com/softecartjs-demo/documentation/SoftecartJS_free.html

Hope you will find it useful.

With Python 3, how about:

try:
    with open(filename, 'x') as tempfile: # OSError if file exists or is invalid
        pass
except OSError:
    # handle error here

With the 'x' option we also don't have to worry about race conditions. See documentation here.

Now, this WILL create a very shortlived temporary file if it does not exist already - unless the name is invalid. If you can live with that, it simplifies things a lot.

In Angular 6, you can do this:

In your service file:

 function_name(data) {
    const url = `the_URL`;
    let input = new FormData();
    input.append('url', data);   // "url" as the key and "data" as value
    return this.http.post(url, input).pipe(map((resp: any) => resp));
  }

In component.ts file: in any function say xyz,

xyz(){
this.Your_service_alias.function_name(data).subscribe(d => {   // "data" can be your file or image in base64 or other encoding
      console.log(d);
    });
}

If you don't want to use any libraries and you have reoccurrences in your data, you can use which with sapply as well.

new_order <- sapply(target, function(x,df){which(df$name == x)}, df=df)
df        <- df[new_order,]

Your main problem is thinking that the variable you declared outside of the template is the same variable being "set" inside the choose statement. This is not how XSLT works, the variable cannot be reassigned. This is something more like what you want:

<xsl:template match="class">
  <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
  <xsl:variable name="subexists">
    <xsl:choose>
      <xsl:when test="joined-subclass">true</xsl:when>
      <xsl:otherwise>false</xsl:otherwise>
    </xsl:choose>
  </xsl:variable>
  subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

And if you need the variable to have "global" scope then declare it outside of the template:

<xsl:variable name="subexists">
  <xsl:choose>
     <xsl:when test="/path/to/node/joined-subclass">true</xsl:when>
     <xsl:otherwise>false</xsl:otherwise>
  </xsl:choose>
</xsl:variable>

<xsl:template match="class">
   subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

I couldn't get the form suggested by @thoredge to work in Gradle 1.11, but this works for me:

home = System.getenv('HOME')

It helps to keep in mind that anything that works in pure Java will work in Gradle too.

You need to store all of the extra rows in the files in your dictionary, not just one of them:

dict1 = {row[0]: row[1:] for row in r}
...
dict2 = {row[0]: row[1:] for row in r}

Then, since the values in the dictionaries are lists, you need to just concatenate the lists together:

w.writerows([[key] + dict1.get(key, []) + dict2.get(key, []) for key in keys])

Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet extends java.util.HashSet. The method add() is overridden in LinkedHashSet. If you have a variable that is of type HashSet, and you call its add() method, it will call the appropriate implementation of add(), based on whether it is a HashSet or a LinkedHashSet. This is called polymorphism.

Method overloading is defining several methods in the same class, that accept different numbers and types of parameters. In this case, the actual method called is decided at compile-time, based on the number and types of arguments. For instance, the method System.out.println() is overloaded, so that you can pass ints as well as Strings, and it will call a different version of the method.

Go to the folder where Python is installed .. and go to Scripts folder .

Do all this in CMD and then type :

pip

to check whether its there or not .

As soon as it shows some list it means that it is there .

Then type

pip install <package name you want to install>

According Oracle and Sun doc, a class can use all classes from its own package and all public classes from other packages. You can access the public classes in another package in two ways.

• The first is simply to add the full package name in front of every class name. For example:

  java.util.Date today = new java.util.Date();

• The simpler, and more common, approach is to use the import statement. The point of the import statement is to give you a shorthand to refer to the classes in the package. Once you use import, you no longer have to give the classes their full names. You can import a specific class or the whole package. You place import statements at the top of your source files (but below any package statements). For example, you can import all classes in the java.util package with the statement Then you can use without a package prefix.

  import java.util.*;

  // Use class in your code with this manner

  Date today = new Date();

As you mentioned in your question that your classes are under the same package, you should not have any problem, it is better just to use class name.

To display images and videos try this:

    Intent intent = new Intent();
    intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(intent, 1);
    startActivityForResult(Intent.createChooser(intent,"Wybierz plik"), SELECT_FILE);

SELECT user_id 
FROM user_logs 
WHERE login_date BETWEEN '2014-02-01' AND '2014-03-01'

Between keyword works exceptionally for a date. it assumes the time is at 00:00:00 (i.e. midnight) for dates.

Faced the same error. In my case , what i did wrong was that i injected the service(named DataService in my case) inside the constructor within the Component but I simply forgot to import it within the component.

 constructor(private dataService:DataService ) {
    console.log("constructor called");
  }

I missed the below import code.

import { DataService } from '../../services/data.service';

same problem happened to me, From this

I have faced the same issue, to solve it:

1- delete (or move) the projects folder (AndroidStudioProjects).

2- Run the Android-Studio (a WELCOME screen will started).

3- From Welcome Screen choose, "Configure -> Project Defaults -> Project Structure)

4- Under Platform Settings choose SDKs.

5- Select Android SDK -> right_click delete.

6- Right_click -> New Sdk -> Android SDK -> choose your SDK dir -> then OK.

7- Choose the Build target -> apply -> OK. enjoy

in a Visual Basic Macro you would use

pName = ActiveWorkbook.Path      ' the path of the currently active file
wbName = ActiveWorkbook.Name     ' the file name of the currently active file
shtName = ActiveSheet.Name       ' the name of the currently selected worksheet

The first sheet in a workbook can be referenced by

ActiveWorkbook.Worksheets(1)

so after deleting the [Report] tab you would use

ActiveWorkbook.Worksheets("Report").Delete
shtName = ActiveWorkbook.Worksheets(1).Name

to "work on that sheet later on" you can create a range object like

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(shtName).[A1]

and continue working on MySheet(rowNum, colNum) etc. ...

shortcut creation of a range object without defining shtName:

Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(1).[A1]

One other way would be to use 4 letter commands to validate if zookeeper service is healthy or not

echo stat | nc <zookeeper ip> 2181
echo mntr | nc <zookeeper ip> 2181
echo isro  | nc <zookeeper ip> 2181

More details on the documentation link below https://zookeeper.apache.org/doc/r3.1.2/zookeeperAdmin.html#sc_zkCommands

More one example:

Follow:

 qryAux = (from q in qryAux where
            q.OrdSeq == (from pp in Sessao.Query<NameTable>() where pp.FieldPk
            == q.FieldPk select pp.OrdSeq).Max() select q);

Equals:

 select t.*   from nametable t  where t.OrdSeq =
        (select max(t2.OrdSeq) from nametable t2 where t2.FieldPk= t.FieldPk)

The simplest and efficient solution is :

pgrep -fl aa.sh

how about this? it works for me! :)

var d = new Date();
var minutes = d.getMinutes().toString().replace(/^(\d)$/, '0$1');

Both the annotations behave exactly in same manner.

Only 2 special characters '!' and '@' are accepted by the annotations @PathVariable and @RequestParam.

To check and confirm the behavior I have created a spring boot application that contains only 1 controller.

 @RestController 
public class Controller 
{
    @GetMapping("/pvar/{pdata}")
    public @ResponseBody String testPathVariable(@PathVariable(name="pdata") String pathdata)
    {
        return pathdata;
    }

    @GetMapping("/rpvar")
    public @ResponseBody String testRequestParam(@RequestParam("param") String paramdata)
    {
        return paramdata;
    }
}

Hitting following Requests I got the same response:

1. localhost:7000/pvar/!@#$%^&*()_+-=[]{}|;':",./<>?
2. localhost:7000/rpvar?param=!@#$%^&*()_+-=[]{}|;':",./<>?

!@ was received as response in both the requests

First of all you should declare a table variable and fill it with your table data and after that, with a WHILE loop, select row one by one and add its value to a nvarchar(max) variable.

    Go
    declare @temp table(
        title nvarchar(50)
    )
    insert into @temp(title)
    select p.Title from dbo.person p
    --
    declare @mainString nvarchar(max)
    set @mainString = '';
    --
    while ((select count(*) from @temp) != 0)
    begin
        declare @itemTitle nvarchar(50)
        set @itemTitle = (select top(1) t.Title from @temp t)
    
        if @mainString = ''
        begin
            set @mainString = @itemTitle
        end
        else
        begin
            set @mainString = concat(@mainString,',',@itemTitle)
        end
    
        delete top(1) from @temp
    
    end
    print @mainString

Using white-space: pre-line allows you to input the text directly in the HTML with line breaks without having to use \n

If you use the innerText property of the element via JavaScript on a non-pre element e.g. a <div>, the \n values will be replaced with <br> in the DOM by default

• innerText: replaces \n with <br>
• innerHTML, textContent: require the use of styling white-space

It depends on how your applying the text, but there are a number of options

const node = document.createElement('div');
node.innerText = '\n Test \n One '

I find grepping grep's output to be very helpful sometimes:

grep -rn "foo=" . | grep -v "Binary file"

Though, that doesn't actually stop it from searching the binary files.

In the specific case of a Rails action (as opposed to the general case of getting the current method name) you can use params[:action]

Alternatively you might want to look into customising the Rails log format so that the action/method name is included by the format rather than it being in your log message.

Here is a summary of the valid solutions provided by all users, for data frames indexed by integer and string.

df.iloc, df.loc and df.at work for both type of data frames, df.iloc only works with row/column integer indices, df.loc and df.at supports for setting values using column names and / or integer indices.

When the specified index does not exist, both df.loc and df.at would append the newly inserted rows/columns to the existing data frame, but df.iloc would raise "IndexError: positional indexers are out-of-bounds". A working example tested in Python 2.7 and 3.7 is as follows:

Here is the simple example of getting request params in a Map.

 @RequestMapping(value="submitForm.html", method=RequestMethod.POST)
     public ModelAndView submitForm(@RequestParam Map<String, String> reqParam) 
       {
          String name  = reqParam.get("studentName");
          String email = reqParam.get("studentEmail");

          ModelAndView model = new ModelAndView("AdmissionSuccess");
          model.addObject("msg", "Details submitted by you::
          Name: " + name + ", Email: " + email );
       }

In this case, it will bind the value of studentName and studentEmail with name and email variables respectively.

function wait(time)
    local duration = os.time() + time
    while os.time() < duration do end
end

This is probably one of the easiest ways to add a wait/sleep function to your script

To both check if it exists and create if it doesn't, including intermediaries:

QDir dir("path/to/dir");
if (!dir.exists())
    dir.mkpath(".");

Passing the dataframes to concat in a dictionary, results in a multi-index dataframe from which you can easily delete the duplicates, which results in a multi-index dataframe with the differences between the dataframes:

import sys
if sys.version_info[0] < 3:
    from StringIO import StringIO
else:
    from io import StringIO
import pandas as pd

DF1 = StringIO("""Date       Fruit  Num  Color 
2013-11-24 Banana 22.1 Yellow

DF2 = StringIO("""Date       Fruit  Num  Color

df1 = pd.read_table(DF1, sep='\s+')
df2 = pd.read_table(DF2, sep='\s+')
#%%
dfs_dictionary = {'DF1':df1,'DF2':df2}
df=pd.concat(dfs_dictionary)
df.drop_duplicates(keep=False)

Result:

             Date   Fruit   Num   Color
DF2 4  2013-11-25   Apple  22.1     Red
    5  2013-11-25  Orange   8.6  Orange

Default capacity of ArrayList is 10. Once the Capacity reaches its maximum capacity, Size of the ArrayList will be 16, once the capacity reaches its maximum capacity of 16, size of the ArrayList will be 25 and keep on increasing based on Data size.....

How? Here is the Answer and Formula

New capacity = (Current Capacity * 3/2) + 1

So, if the default capacity is 10, then

Current Capacity = 10
New capacity = (10 * 3/2) + 1
Output is 16

One of the way is Using below sql queries

--Size of All Table Space

--1. Used Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "USED SPACE(IN GB)" FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME
--2. Free Space
SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS "FREE SPACE(IN GB)" FROM   USER_FREE_SPACE GROUP BY TABLESPACE_NAME

--3. Both Free & Used
SELECT USED.TABLESPACE_NAME, USED.USED_BYTES AS "USED SPACE(IN GB)",  FREE.FREE_BYTES AS "FREE SPACE(IN GB)"
FROM
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS USED_BYTES FROM USER_SEGMENTS GROUP BY TABLESPACE_NAME) USED
INNER JOIN
(SELECT TABLESPACE_NAME,TO_CHAR(SUM(NVL(BYTES,0))/1024/1024/1024, '99,999,990.99') AS FREE_BYTES FROM  USER_FREE_SPACE GROUP BY TABLESPACE_NAME) FREE
ON (USED.TABLESPACE_NAME = FREE.TABLESPACE_NAME);

If your 13 digit "number" is really text, that is you don't intend to do any math on it, you can precede it with an apostrophe

Sheet3.Range("c" & k).Value = "'" & Sheet2.Range("c" & i).Value

But I don't see how a 13 digit number would ever get past the If statement because it would always be greater than 1000. Here's an alternate version

Sub CommandClick()

    Dim rCell As Range
    Dim rNext As Range

    For Each rCell In Sheet2.Range("C1:C30000").Cells
        If rCell.Value >= 100 And rCell.Value < 1000 Then
            Set rNext = Sheet3.Cells(Sheet3.Rows.Count, 1).End(xlUp).Offset(1, 0)
            rNext.Resize(1, 3).Value = rCell.Offset(0, -2).Resize(1, 3).Value
        End If
    Next rCell

End Sub

In MongoDB Stitch functions it can be done using BSON like below:

Use the ObjectId helper in the BSON utility package for this purpose like in the follwing example:

var id = "5bb9e9f84186b222c8901149";  
BSON.ObjectId(id);

If, as I just encountered, you happen to have a jar file listed in the Project Structures->Libraries that is not in your classpath, the correct answer can be found by following the link given by @CrazyCoder above: Look here http://www.jetbrains.com/idea/webhelp/configuring-module-dependencies-and-libraries.html

This says that to add the jar file as a module dependency within the Project Structure dialog:

1. Open Project Structure
2. Select Modules, then click on the module for which you want the dependency
3. Choose the Dependencies tab
4. Click the '+' at the bottom of the page and choose the appropriate way to connect to the library file. If the jar file is already listed in Libraries, then select 'Library'.

I implemented maxlength behaviour on textarea recently, and run into problem described in this question: Chrome counts characters wrong in textarea with maxlength attribute.

So all implementations listed here will work little buggy. To solve this issue I add .replace(/(\r\n|\n|\r)/g, "11") before .length. And kept it in mind when cuting string.

I ended with something like this:

var maxlength = el.attr("maxlength");
var val = el.val();
var length = val.length;
var realLength = val.replace(/(\r\n|\n|\r)/g, "11").length;
if (realLength > maxlength) {
    el.val(val.slice(0, maxlength - (realLength - length)));
}

Don't sure if it solves problem completely, but it works for me for now.

For me none of the packages mentioned above did help.

I finally managed to install lxml after running:

sudo apt-get install python3.5-dev

Other than your IDE giving you hints when you pass null to methods that expect the argument to not be null, there are further advantages:

• Static code analysis tools can test the same as your IDE (e.g. FindBugs)
• You can use Aspect-oriented programming (AOP) to check these assertions

This can help your code be more maintainable (since you do not need null checks) and less error-prone.

Note that I don't recommend a fixed IP for containers in Docker unless you're doing something that allows routing from outside to the inside of your container network (e.g. macvlan). DNS is already there for service discovery inside of the container network and supports container scaling. And outside the container network, you should use exposed ports on the host. With that disclaimer, here's the compose file you want:

version: '2'

services:
  mysql:
    container_name: mysql
    image: mysql:latest
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=root
    ports:
     - "3306:3306"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.5

  apigw-tomcat:
    container_name: apigw-tomcat
    build: tomcat/.
    ports:
     - "8080:8080"
     - "8009:8009"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.6
    depends_on:
     - mysql

networks:
  vpcbr:
    driver: bridge
    ipam:
     config:
       - subnet: 10.5.0.0/16
         gateway: 10.5.0.1

First Convert your string into HTML then convert it into spannable. do as suggest the following codes.

 Spannable spannable = new SpannableString(Html.fromHtml(labelText));
                    
spannable.setSpan(new ForegroundColorSpan(Color.parseColor(color)), spannable.toString().indexOf("•"), spannable.toString().lastIndexOf("•") + 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
            

This is a solution suggested by the MySQl manual:

If expr is given as an argument to LAST_INSERT_ID(), the value of the argument is returned by the function and is remembered as the next value to be returned by LAST_INSERT_ID(). This can be used to simulate sequences:

Create a table to hold the sequence counter and initialize it:

    mysql> CREATE TABLE sequence (id INT NOT NULL);
    mysql> INSERT INTO sequence VALUES (0);

Use the table to generate sequence numbers like this:

    mysql> UPDATE sequence SET id=LAST_INSERT_ID(id+1);
    mysql> SELECT LAST_INSERT_ID();

The UPDATE statement increments the sequence counter and causes the next call to LAST_INSERT_ID() to return the updated value. The SELECT statement retrieves that value. The mysql_insert_id() C API function can also be used to get the value. See Section 23.8.7.37, “mysql_insert_id()”.

You can generate sequences without calling LAST_INSERT_ID(), but the utility of using the function this way is that the ID value is maintained in the server as the last automatically generated value. It is multi-user safe because multiple clients can issue the UPDATE statement and get their own sequence value with the SELECT statement (or mysql_insert_id()), without affecting or being affected by other clients that generate their own sequence values.

For HTTP Basic Auth:

curl -H "Authorization: Basic <_your_token_>" http://www.example.com

replace _your_token_ and the URL.

Permanent generation

If you want to use it in plain SQL, I would let the store procedure fill a table or temp table with the resulting rows (or go for @Tony Andrews approach).
If you want to use @Thilo's solution, you have to loop the cursor using PL/SQL. Here an example: (I used a procedure instead of a function, like @Thilo did)

create or replace procedure myprocedure(retval in out sys_refcursor) is
begin
  open retval for
    select TABLE_NAME from user_tables;
end myprocedure;

 declare 
   myrefcur sys_refcursor;
   tablename user_tables.TABLE_NAME%type;
 begin
   myprocedure(myrefcur);
   loop
     fetch myrefcur into tablename;
     exit when myrefcur%notfound;
     dbms_output.put_line(tablename);
   end loop;
   close myrefcur;
 end;

This thread seems to answer your question : simultaneous-read-write-a-file

Basically, what you need is to declare two FileStream, one for read operations, the other for write operations. Writer Filestream needs to open your file in 'Append' mode.

Try this:

return Redirect("http://www.website.com");

This depends on what you mean by "get the range of selection". If you mean getting the range address (like "A1:B1") then use the Address property of Selection object - as Michael stated Selection object is much like a Range object, so most properties and methods works on it.

Sub test()
    Dim myString As String
    myString = Selection.Address
End Sub

I find this alternative more convenient:

1. Click the "Run Button Dropdown"
2. From the list choose Profile
3. The program "Instruments" should open where you can also choose Zombies
4. Now you can interact with your app and try to cause the error
5. As soon as the error happens you should get a hint on when your object was released and therefore deallocated.

As soon as a zombie is detected you then get a neat "Zombie Stack" that shows you when the object in question was allocated and where it was retained or released:

Event Type    RefCt     Responsible Caller
Malloc            1     -[MyViewController loadData:]
Retain            2     -[MyDataManager initWithBaseURL:]
Release           1     -[MyDataManager initWithBaseURL:]
Release           0     -[MyViewController loadData:]
Zombie           -1     -[MyService prepareURLReuqest]

Advantages compared to using the diagnostic tab of the Xcode Schemes:

1. If you forget to uncheck the option in the diagnostic tab there no objects will be released from memory.

2. You get a more detailed stack that shows you in what methods your corrupt object was allocated / released or retained.

You can inspect elements of a website in your Android device using Chrome browser.

Open your Chrome browser and go to the website you want to inspect.

Go to the address bar and type "view-source:" before the "HTTP" and reload the page.

As of HTML5, buttons support the formaction attribute. Best of all, no Javascript or trickery is needed.

<form>_x000D_
  <button formaction="http://stackoverflow.com">Go to Stack Overflow!</button>_x000D_
</form>

Caveats

• Must be surrounded by <form> tags.
• <button> type must be "submit" (or unspecified), I couldn't get it working with type "button." Which brings up point below.
• Overrides the default action in a form. In other words, if you do this inside another form it's going to cause a conflict.

Reference: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button#attr-formaction Browser Support: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button#Browser_compatibility

Try this:

$("input[type=checkbox]").prop('checked', true).uniform();

I found a better way to pass parameters to the popup window and even to retrieve parameters from it :

In the main page :

var popupwindow;
var sharedObject = {};

function openPopupWindow()
{
   // Define the datas you want to pass
   sharedObject.var1 = 
   sharedObject.var2 = 
   ...

   // Open the popup window
   window.open(URL_OF_POPUP_WINDOW, NAME_OF_POPUP_WINDOW, POPUP_WINDOW_STYLE_PROPERTIES);
   if (window.focus) { popupwindow.focus(); }
}

function closePopupWindow()
{
    popupwindow.close();

    // Retrieve the datas from the popup window
    = sharedObject.var1;
    = sharedObject.var2;
    ...
}

In the popup window :

var sharedObject = window.opener.sharedObject;

// function you have to to call to close the popup window
function myclose()
{
    //Define the parameters you want to pass to the main calling window
    sharedObject.var1 = 
    sharedObject.var2 = 
    ...
    window.opener.closePopupWindow();
}

That's it !

And this is very convenient because:

• You have not to set parameters in the URL of the popup window.
• No form to define
• You can use illimited parameters even objects.
• Bi-directionnal : you can pass parameters AND, if you want you, can retreive new parameters.
• Very easy to implement.

Have Fun!

JAXB Limitation.

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

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

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

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

You can create actions with text in 2 ways:

1- From XML:

<item android:id="@id/resource_name"
      android:title="text"
      android:icon="@drawable/drawable_resource_name"
      android:showAsAction="withText" />

When inflating the menu, you should call getSupportMenuInflater() since you are using ActionBarSherlock.

2- Programmatically:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuItem item = menu.add(Menu.NONE, ID, POSITION, TEXT);
    item.setIcon(R.drawable.drawable_resource_name);
    item.setShowAsAction(MenuItem.SHOW_AS_ACTION_WITH_TEXT);

    return true;
}

Make sure you import com.actionbarsherlock.view.Menu and com.actionbarsherlock.view.MenuItem.

@Casperah pointed out that i'm thinking about it wrong:

• A TextBox doesn't have lines
• it has text
• that text can be split on the CRLF into lines, if requested
• but there is no notion of lines

The question then is how to accomplish what i want, rather than what WinForms lets me.

There are subtle bugs in the other given variants:

• textBox1.AppendText("Hello" + Environment.NewLine);
• textBox1.AppendText("Hello" + "\r\n");
• textBox1.Text += "Hello\r\n"
• textbox1.Text += System.Environment.NewLine + "brown";

They either append or prepend a newline when one (might) not be required.

So, extension helper:

public static class WinFormsExtensions
{
   public static void AppendLine(this TextBox source, string value)
   {
      if (source.Text.Length==0)
         source.Text = value;
      else
         source.AppendText("\r\n"+value);
   }
}

So now:

textBox1.Clear();
textBox1.AppendLine("red");
textBox1.AppendLine("green");
textBox1.AppendLine("blue");

and

textBox1.AppendLine(String.Format("Processing file {0}", filename));

The PHP json_encode function translates the data passed to it to a JSON string which can then be output to a JavaScript variable.The PHP json_encode function returns a string containing the JSON equivalent of the value passed to it.

<?php
$ar = array('apple', 'orange', 'banana', 'strawberry');
echo json_encode($ar); // ["apple","orange","banana","strawberry"]
?>

You can pass the JSON string output by json_encode to a JavaScript variable as follows:

<script type="text/javascript">
// pass PHP variable declared above to JavaScript variable
var ar = <?php echo json_encode($ar) ?>;
</script>

A numerically indexed PHP array is translated to an array literal in the JSON string. A JSON_FORCE_OBJECT option can be used if you want the array to be output as an object instead:

<?php
echo json_encode($ar, JSON_FORCE_OBJECT);
// {"0":"apple","1":"orange","2":"banana","3":"strawberry"} 
?>

Associative Array Example:

<?php
$book = array(
    "title" => "JavaScript: The Definitive Guide",
    "author" => "David Flanagan",
    "edition" => 6
);
?>
<script type="text/javascript">
var book = <?php echo json_encode($book, JSON_PRETTY_PRINT) ?>;
/* var book = {
    "title": "JavaScript: The Definitive Guide",
    "author": "David Flanagan",
    "edition": 6
}; */
alert(book.title);
</script>

Notice that PHP's associative array becomes an object literal in JavaScript. We use the JSON_PRETTY_PRINT option as the second argument to json_encode to display the output in a readable format.

You can access object properties using dot syntax, as displayed with the alert included above, or square bracket syntax: book['title'].

here you can find more information and details.

Another way to do it programmatically which looks a bit less like a hack than the Paint way:

Instead of doing:

tv.setText(s);

do:

private static final StrikethroughSpan STRIKE_THROUGH_SPAN = new StrikethroughSpan();
...
tv.setText(s, TextView.BufferType.SPANNABLE);
Spannable spannable = (Spannable) tv.getText();
spannable.setSpan(STRIKE_THROUGH_SPAN, 0, s.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

A good place to start is this: https://github.com/wasabeef/recyclerview-animators/blob/master/animators/src/main/java/jp/wasabeef/recyclerview/adapters/AnimationAdapter.java

You don't even need the full library, that class is enough. Then if you just implement your Adapter class giving an animator like this:

@Override
protected Animator[] getAnimators(View view) {
    return new Animator[]{
            ObjectAnimator.ofFloat(view, "translationY", view.getMeasuredHeight(), 0)
    };
}

@Override
public long getItemId(final int position) {
    return getWrappedAdapter().getItemId(position);
}

you'll see items appearing from the bottom as they scroll, also avoiding the problem with the fast scroll.

set cornerRadious Property for round View

set masksToBounds Boolean Value for image will not still be drawn outside the corner radius boundary

view.layer.cornerRadius = 5;

view.layer.masksToBounds = YES;

I ran into this on my Mac using the MacPorts vim with +python. Problem was that the MacPorts vim will only bind to python 2.5 with +python, while my extensions were installed under python 2.7. Installing the extensions using pip-2.5 solved it.

You can insert into a varbinary(max) field using T-SQL within SQL Server Management Studio and in particular using the OPENROWSET commmand.

For example:

INSERT Production.ProductPhoto 
(
    ThumbnailPhoto, 
    ThumbnailPhotoFilePath, 
    LargePhoto, 
    LargePhotoFilePath
)
SELECT ThumbnailPhoto.*, null, null, N'tricycle_pink.gif'
FROM OPENROWSET 
    (BULK 'c:\images\tricycle.jpg', SINGLE_BLOB) ThumbnailPhoto

Take a look at the following documentation for a good example/walkthrough

Working With Large Value Types

Note that the file path in this case is relative to the targeted SQL server and not your client running this command.

Things to note:

• validate event handler bound within the document.ready function - otherwise the inputs won't exist when the JS is loaded
• using keyup

In saying that, validation is a solved problem there are frameworks that implement this functionality.

http://bassistance.de/jquery-plugins/jquery-plugin-validation/

I'd suggest using one of these rather than reimplementing Validation for every app you write.

You are making it complicated. string is already nullable. You don't need to make it more nullable. Take out the ? on the property type.

You can use the description method inherited by NSDictionary from NSObject, or write a custom method that formats NSDictionary to your liking.

This does not do what you expect:

if var is 'stringone' or 'stringtwo':
    dosomething()

It is the same as:

if (var is 'stringone') or 'stringtwo':
    dosomething()

Which is always true, since 'stringtwo' is considered a "true" value.

There are two alternatives:

if var in ('stringone', 'stringtwo'):
    dosomething()

Or you can write separate equality tests,

if var == 'stringone' or var == 'stringtwo':
    dosomething()

Don't use is, because is compares object identity. You might get away with it sometimes because Python interns a lot of strings, just like you might get away with it in Java because Java interns a lot of strings. But don't use is unless you really want object identity.

True
>>> 'a' + 'b' is 'abc'[:2]
False # but could be True
>>> 'a' + 'b' is 'ab'

Drag a XLS file to it (like "test.xls"). It will create a converted CSV file named "test.xls.csv". Then, rename it to "test.csv". Done.

If you want to just shift everything down you can use:

Rows(1).Insert shift:=xlShiftDown

Similarly to shift everything over:

Columns(1).Insert shift:=xlShiftRight

Continuum Analytics now provides instructions on how to setup Anaconda with various IDEs including Pycharm here. However, with Pycharm 5.0.1 running on Unbuntu 15.10 Project Interpreter settings were found via the File | Settings and then under the Project branch of the treeview on the Settings dialog.

I see 4 issues with your code:

• In your timer method you are always setting your current count to 10
• You try to update the state in render method
• You do not use setState method to actually change the state
• You are not storing your intervalId in the state

Let's try to fix that:

componentDidMount: function() {
   var intervalId = setInterval(this.timer, 1000);
   // store intervalId in the state so it can be accessed later:
   this.setState({intervalId: intervalId});
},

componentWillUnmount: function() {
   // use intervalId from the state to clear the interval
   clearInterval(this.state.intervalId);
},

timer: function() {
   // setState method is used to update the state
   this.setState({ currentCount: this.state.currentCount -1 });
},

render: function() {
    // You do not need to decrease the value here
    return (
      <section>
       {this.state.currentCount}
      </section>
    );
}

This would result in a timer that decreases from 10 to -N. If you want timer that decreases to 0, you can use slightly modified version:

timer: function() {
   var newCount = this.state.currentCount - 1;
   if(newCount >= 0) { 
       this.setState({ currentCount: newCount });
   } else {
       clearInterval(this.state.intervalId);
   }
},

Pattern satisfy, these below criteria

1. Password Length 8 and Maximum 15 character
2. Require Unique Chars
3. Require Digit
4. Require Lower Case
5. Require Upper Case

^(?!.*([A-Za-z0-9]))(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[#?!@$%^&*-]).{8,15}$

It is a public final field for the array type. You can refer to the document below:

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.

No, don't spoil it with a break. This is the last remaining stronghold for the use of goto.

As far as I know, cookies are limited by the "same origin" policy. However, with CORS you can receive and use the "Server B" cookies to establish a persistent session from "Server A" on "Server B".

Although, this requires some headers on "Server B":

Access-Control-Allow-Origin: http://server-a.domain.com
Access-Control-Allow-Credentials: true

And you will need to send the flag "withCredentials" on all the "Server A" requests (ex: xhr.withCredentials = true;)

You can read about it here:

http://www.html5rocks.com/en/tutorials/cors/

https://developer.mozilla.org/en-US/docs/HTTP/Access_control_CORS

It can easily happen if you try to undo changes you've made by re-checking-out files and not quite getting the syntax right.

You can look at the output of git log - you could paste the tail of the log here since the last successful commit, and we could all see what you did. Or you could paste-bin it and ask nicely in #git on freenode IRC.

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

You can extend Desheng Li's method further by allowing an iterations count to do multiple flashes like so:

// Extend jquery with flashing for elements
$.fn.flash = function(duration, iterations) {
    duration = duration || 1000; // Default to 1 second
    iterations = iterations || 1; // Default to 1 iteration
    var iterationDuration = Math.floor(duration / iterations);

    for (var i = 0; i < iterations; i++) {
        this.fadeOut(iterationDuration).fadeIn(iterationDuration);
    }
    return this;
}

Then you can call the method with a time and number of flashes:

$("#someElementId").flash(1000, 4); // Flash 4 times over a period of 1 second

Here's a shell script that does it without calling other programs:

#! /bin/env bash

You can get info on the display from the DisplayMetrics struct:

DisplayMetrics metrics = getResources().getDisplayMetrics();

Though Android doesn't use a direct pixel mapping, it uses a handful of quantized Density Independent Pixel values then scales to the actual screen size. So the metrics.densityDpi property will be one of the DENSITY_xxx constants (120, 160, 213, 240, 320, 480 or 640 dpi).

If you need the actual lcd pixel density (perhaps for an OpenGL app) you can get it from the metrics.xdpi and metrics.ydpi properties for horizontal and vertical density respectively.

If you are targeting API Levels earlier than 4. The metrics.density property is a floating point scaling factor from the reference density (160dpi). The same value now provided by metrics.densityDpi can be calculated

int densityDpi = (int)(metrics.density * 160f);

If you are having pre built data base than copy it in asset folder and create an new class as DataBaseHelper which implements SQLiteOpenHelper Than use following code:

Hope this will help you...

you have to rename the column to an other name because TABLE is reserved by Oracle.

You can see all reserved words of Oracle in the oracle view V$RESERVED_WORDS.

function removeParam(parameter)
{
  var url=document.location.href;
  var urlparts= url.split('?');

 if (urlparts.length>=2)
 {
  var urlBase=urlparts.shift(); 
  var queryString=urlparts.join("?"); 

  var prefix = encodeURIComponent(parameter)+'=';
  var pars = queryString.split(/[&;]/g);
  for (var i= pars.length; i-->0;)               
      if (pars[i].lastIndexOf(prefix, 0)!==-1)   
          pars.splice(i, 1);
  url = urlBase+'?'+pars.join('&');
  window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .

}
return url;
}

This will resolve your problem

If you are running the command from a POSIX-compliant shell, like bash, you can set the environment variable like this:

PYTHONPATH="/path/to" python somescript.py somecommand

If it's all on one line, the PYTHONPATH environment value applies only to that one command.

$ echo $PYTHONPATH

$ python -c 'import sys;print("/tmp/pydir" in sys.path)'
False
$ PYTHONPATH=/tmp/pydir python -c 'import sys;print("/tmp/pydir" in sys.path)'
True
$ echo $PYTHONPATH
