In case of continuous numbers randint or randrange are probably the best choices but if you have several distinct values in a sequence (i.e. a list) you could also use choice:

>>> import random
>>> values = list(range(10))
>>> random.choice(values)
5

choice also works for one item from a not-continuous sample:

>>> values = [1, 2, 3, 5, 7, 10]
>>> random.choice(values)
7

If you need it "cryptographically strong" there's also a secrets.choice in python 3.6 and newer:

>>> import secrets
>>> values = list(range(10))
>>> secrets.choice(values)
2

Use <div class="row"> and <div class="form-group col-xs-6">

if you are using numpy in your solution for faster computation use this:

import numpy as np
x = np.array([2,5,77,77,77,77,77,77,77,9,0,3,3,3,3,3])
y = np.bincount(x,minlength = max(x))
y = np.argmax(y)   
print(y)  #outputs 77

While what you want to accomplish may be useful, there is another option which I believe you might be overlooking that is much more simple.

You are correct, the Bootstrap tables act strangely when you have columns which are not fixed height. However, there is a bootstrap class created to combat this issue and perform responsive resets.

simply create an empty <div class="clearfix"></div> before the start of each new row to allow the floats to reset and the columns to return to their correct positions.

here is a bootply.

My experience is that Ionic Pro (https://ionicframework.com/pro) can do the most of the Development and Publish job but you still need Mac or Mac in cloud at these steps:

• create .p12 Certification file
• upload the .ipa file to the App Store

After you created your Certification file, You can upload it to Ionic Pro. You can build .ipa files with proper credentials in cloud. But unfortunately I didn't found another way to upload the .ipa file to App Store, only with Application Loader from Mac.

So I decided to use a pay-as-you-go Mac in cloud account (you pay only for minutes you are logged in) since the time I spend on Mac is very limited (few minutes per App publication).

How about something like this:

SELECT c.constraint_name, c.constraint_type, c2.constraint_name, c2.constraint_type, c2.table_name
  FROM dba_constraints c JOIN dba_constraints c2 ON (c.r_constraint_name = c2.constraint_name)
 WHERE c.table_name = <TABLE_OF_INTEREST>
   AND c.constraint_TYPE = 'R';

Store them as two fields for phone numbers - a "number" and a "mask" as TinyText types which do not need more than 255 items.

Before we store the files we parse the phone number to get the formatting that has been used and that creates the mask, we then store the number a digits only e.g.

Input: (0123) 456 7890
Number: 01234567890
Mask: (nnnn)_nnn_nnnn

Theoretically this allows us to perform comparison searches on the Number field such as getting all phone numbers that begin with a specific area code, without having to worry how it was input by the users

Based on what type of RFC standard encoding you want to perform or if you need to customize your encoding you might want to create your own class.

/**
 * UrlEncoder make it easy to encode your URL
 */
class UrlEncoder{
    public const STANDARD_RFC1738 = 1;
    public const STANDARD_RFC3986 = 2;
    public const STANDARD_CUSTOM_RFC3986_ISH = 3;
    // add more here

    static function encode($string, $rfc){
        switch ($rfc) {
            case self::STANDARD_RFC1738:
                return  urlencode($string);
                break;
            case self::STANDARD_RFC3986:
                return rawurlencode($string);
                break;
            case self::STANDARD_CUSTOM_RFC3986_ISH:
                // Add your custom encoding
                $entities = ['%21', '%2A', '%27', '%28', '%29', '%3B', '%3A', '%40', '%26', '%3D', '%2B', '%24', '%2C', '%2F', '%3F', '%25', '%23', '%5B', '%5D'];
                $replacements = ['!', '*', "'", "(", ")", ";", ":", "@", "&", "=", "+", "$", ",", "/", "?", "%", "#", "[", "]"];
                return str_replace($entities, $replacements, urlencode($string));
                break;
            default:
                throw new Exception("Invalid RFC encoder - See class const for reference");
                break;
        }
    }
}

Use example:

$dataString = "https://www.google.pl/search?q=PHP is **great**!&id=123&css=#kolo&[email protected])";

$dataStringUrlEncodedRFC1738 = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_RFC1738);
$dataStringUrlEncodedRFC3986 = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_RFC3986);
$dataStringUrlEncodedCutom = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_CUSTOM_RFC3986_ISH);

Will output:

string(126) "https%3A%2F%2Fwww.google.pl%2Fsearch%3Fq%3DPHP+is+%2A%2Agreat%2A%2A%21%26id%3D123%26css%3D%23kolo%26email%3Dme%40liszka.com%29"

Does:

Set Sheets("Output").Range("$A$1:$A$500") =  Sheets(sheet_).Range("$A$1:$A$500")

...work? (I don't have Excel in front of me, so can't test.)

You can use this (the French locale has , for decimal separator)

NumberFormat nf = NumberFormat.getInstance(Locale.FRANCE);
nf.parse(p);

Or you can use java.text.DecimalFormat and set the appropriate symbols:

DecimalFormat df = new DecimalFormat();
DecimalFormatSymbols symbols = new DecimalFormatSymbols();
symbols.setDecimalSeparator(',');
symbols.setGroupingSeparator(' ');
df.setDecimalFormatSymbols(symbols);
df.parse(p);

Another summary:

You need to use both. ETags are a "server side" information. Expires are a "Client side" caching.

• Use ETags except if you have a load-balanced server. They are safe and will let clients know they should get new versions of your server files every time you change something on your side.

• Expires must be used with caution, as if you set a expiration date far in the future but want to change one of the files immediatelly (a JS file for instance), some users may not get the modified version until a long time!

Check my fork of LazyList. Basically, I improve the LazyList by delaying the call of the ImageView and create two methods:

1. When you need to put something like "Loading image..."
2. When you need to show the downloaded image.

I also improved the ImageLoader by implementing a singleton in this object.

After you extract your "selenium-java-.zip" file you need to configure your build path from your IDE. Import all the jar files under "lib" folder and both selenium standalone server & Selenium java version jar files.

Suppose you want to add those flags (better to declare them in a constant):

SET(GCC_COVERAGE_COMPILE_FLAGS "-fprofile-arcs -ftest-coverage")
SET(GCC_COVERAGE_LINK_FLAGS    "-lgcov")

There are several ways to add them:

1. The easiest one (not clean, but easy and convenient, and works only for compile flags, C & C++ at once):

   add_definitions(${GCC_COVERAGE_COMPILE_FLAGS})
   

2. Appending to corresponding CMake variables:

   SET(CMAKE_CXX_FLAGS  "${CMAKE_CXX_FLAGS} ${GCC_COVERAGE_COMPILE_FLAGS}")
   SET(CMAKE_EXE_LINKER_FLAGS  "${CMAKE_EXE_LINKER_FLAGS} ${GCC_COVERAGE_LINK_FLAGS}")
   

3. Using target properties, cf. doc CMake compile flag target property and need to know the target name.

   get_target_property(TEMP ${THE_TARGET} COMPILE_FLAGS)
   if(TEMP STREQUAL "TEMP-NOTFOUND")
     SET(TEMP "") # Set to empty string
   else()
     SET(TEMP "${TEMP} ") # A space to cleanly separate from existing content
   endif()
   # Append our values
   SET(TEMP "${TEMP}${GCC_COVERAGE_COMPILE_FLAGS}" )
   set_target_properties(${THE_TARGET} PROPERTIES COMPILE_FLAGS ${TEMP} )
   

Right now I use method 2.

According to Wikipedia,

Views can provide many advantages over tables:

• Views can represent a subset of the data contained in a table.

• Views can limit the degree of exposure of the underlying tables to the outer world: a given user may have permission to query the view, while denied access to the rest of the base table.

• Views can join and simplify multiple tables into a single virtual table.

• Views can act as aggregated tables, where the database engine aggregates data (sum, average, etc.) and presents the calculated results as part of the data.

• Views can hide the complexity of data. For example, a view could appear as Sales2000 or Sales2001, transparently partitioning the actual underlying table.

• Views take very little space to store; the database contains only the definition of a view, not a copy of all the data that it presents.

• Views can provide extra security, depending on the SQL engine used.

Ok, this might be a little after the fact, but .promise() should also achieve what you're after.

Promise documentation

An example from a project i'm working on:

$( '.panel' )
    .fadeOut( 'slow')
    .promise()
    .done( function() {
        $( '#' + target_panel ).fadeIn( 'slow', function() {});
    });

:)

Here's something along the same lines. Chances are, you'll be using less anyway, so try this:

less -p pattern file

It will highlight the pattern and jump to the first occurrence of it in the file.

You can jump to the next occurence with n and to the previous occurence with p. Quit with q.

The format string attack on printf you mentioned isn't specific to the "%x" formatting - in any case where printf has more formatting parameters than passed variables, it will read values from the stack that do not belong to it. You will get the same issue with %d for example. %x is useful when you want to see those values as hex.

As explained in previous answers, %08x will produce a 8 digits hex number, padded by preceding zeros.

Using the formatting in your code example in printf, with no additional parameters:

printf ("%08x %08x %08x %08x");

Will fetch 4 parameters from the stack and display them as 8-digits padded hex numbers.

You are correct in thinking that display is not animatable. It won't work, and you shouldn't bother including it in keyframe animations.

visibility is technically animatable, but in a round about way. You need to hold the property for as long as needed, then snap to the new value. visibility doesn't tween between keyframes, it just steps harshly.

.ele {_x000D_
  width: 60px;_x000D_
  height: 60px;_x000D_
  _x000D_
  background-color: #ff6699;_x000D_
  animation: 1s fadeIn;_x000D_
  animation-fill-mode: forwards;_x000D_
  _x000D_
  visibility: hidden;_x000D_
}_x000D_
_x000D_
.ele:hover {_x000D_
  background-color: #123;_x000D_
}_x000D_
_x000D_
@keyframes fadeIn {_x000D_
  99% {_x000D_
    visibility: hidden;_x000D_
  }_x000D_
  100% {_x000D_
    visibility: visible;_x000D_
  }_x000D_
}

<div class="ele"></div>

If you want to fade, you use opacity. If you include a delay, you'll need visibility as well, to stop the user from interacting with the element while it's not visible.

.ele {_x000D_
  width: 60px;_x000D_
  height: 60px;_x000D_
  _x000D_
  background-color: #ff6699;_x000D_
  animation: 1s fadeIn;_x000D_
  animation-fill-mode: forwards;_x000D_
  _x000D_
  visibility: hidden;_x000D_
}_x000D_
_x000D_
.ele:hover {_x000D_
  background-color: #123;_x000D_
}_x000D_
_x000D_
@keyframes fadeIn {_x000D_
  0% {_x000D_
    opacity: 0;_x000D_
  }_x000D_
  100% {_x000D_
    visibility: visible;_x000D_
    opacity: 1;_x000D_
  }_x000D_
}

<div class="ele"></div>

Both examples use animation-fill-mode, which can hold an element's visual state after an animation ends.

If you are on Linux, and performance is not an issue, you may use the exec function from child_process module, to execute a Bash command:

const { exec } = require('child_process');
exec('cp -r source dest', (error, stdout, stderr) => {...});

In some cases, I found this solution cleaner than downloading an entire module or even using the fs module.

How about head ?

echo alonglineoftext | head -c 9

In my use case we had a similar need for CI CD. We used git flow with develop and master branches. Developers are free to merge their changes directly to develop or via a pull request from a feature branch. However to master we merge only the stable commits from the develop branch in an automated way via Jenkins.

In this case doing cherry-pick is not a good option. However we create a local-branch from the commit-id then merge that local-branch to master and perform mvn clean verify(we use maven). If success then release production version artifact to nexus using maven release plugin with localCheckout=true option and pushChanges=false. Finally when everything is success then push the changes and tag to origin.

A sample code snippet:

Assuming you are on master if done manually. However on jenkins, when you checkout the repo you will be on the default branch(master if configured).

git pull  // Just to pull any changes.
git branch local-<commitd-id> <commit-id>  // Create a branch from the given commit-id
git merge local-<commit-id>  // Merge that local branch to master.
mvn clean verify   // Verify if the code is build able
mvn <any args> release:clean release:prepare release:perform // Release artifacts
git push origin/master  // Push the local changes performed above to origin.
git push origin <tag>  // Push the tag to origin

This will give you a full control with a fearless merge or conflict hell.

Feel free to advise in case there is any better option.

To call a sub inside another sub you only need to do:

Call Subname()

So where you have CalculateA(Nc,kij, xi, a1, a) you need to have call CalculateA(Nc,kij, xi, a1, a)

As the which runs first problem it's for you to decide, when you want to run a sub you can go to the macro list select the one you want to run and run it, you can also give it a key shortcut, therefore you will only have to press those keys to run it. Although, on secondary subs, I usually do it as Private sub CalculateA(...) cause this way it does not appear in the macro list and it's easier to work

Hope it helps, Bruno

PS: If you have any other question just ask, but this isn't a community where you ask for code, you come here with a question or a code that isn't running and ask for help, not like you did "It would be great if you could write it in the Excel VBA format."

Formats

Python docstrings can be written following several formats as the other posts showed. However the default Sphinx docstring format was not mentioned and is based on reStructuredText (reST). You can get some information about the main formats in this blog post.

Note that the reST is recommended by the PEP 287

There follows the main used formats for docstrings.

- Epytext

Historically a javadoc like style was prevalent, so it was taken as a base for Epydoc (with the called Epytext format) to generate documentation.

Example:

"""
This is a javadoc style.

@param param1: this is a first param
@param param2: this is a second param
@return: this is a description of what is returned
@raise keyError: raises an exception
"""

- reST

Nowadays, the probably more prevalent format is the reStructuredText (reST) format that is used by Sphinx to generate documentation. Note: it is used by default in JetBrains PyCharm (type triple quotes after defining a method and hit enter). It is also used by default as output format in Pyment.

Example:

"""
This is a reST style.

:param param1: this is a first param
:param param2: this is a second param
:returns: this is a description of what is returned
:raises keyError: raises an exception
"""

- Google

Google has their own format that is often used. It also can be interpreted by Sphinx (ie. using Napoleon plugin).

Example:

"""
This is an example of Google style.

Args:
    param1: This is the first param.
    param2: This is a second param.

Returns:
    This is a description of what is returned.

Raises:
    KeyError: Raises an exception.
"""

Even more examples

- Numpydoc

Note that Numpy recommend to follow their own numpydoc based on Google format and usable by Sphinx.

"""
My numpydoc description of a kind
of very exhautive numpydoc format docstring.

Parameters
----------
first : array_like
    the 1st param name `first`
second :
    the 2nd param
third : {'value', 'other'}, optional
    the 3rd param, by default 'value'

Returns
-------
string
    a value in a string

Raises
------
KeyError
    when a key error
OtherError
    when an other error
"""

Converting/Generating

It is possible to use a tool like Pyment to automatically generate docstrings to a Python project not yet documented, or to convert existing docstrings (can be mixing several formats) from a format to an other one.

Note: The examples are taken from the Pyment documentation

//MARK: does not seem to work for me in Xcode 6.3.2. However, this is what I did to get it to work:

1) Code:

import Cocoa

class MainWindowController: NSWindowController {

    //MARK: - My cool methods

    func fly() {
    }

    func turnInvisible() {

    }
}

2) In the jump bar nothing appears to change when adding the //MARK: comment. However, if I click on the rightmost name in the jump bar, in my case it says MainWindowController(with a leading C icon), then a popup window will display showing the effects of the //MARK: comment, namely a heading that says "My cool methods":

3) I also notice that if I click on one of the methods in my code, then the method becomes the rightmost entry in the jump bar. In order to get MainWindowController(with a leading C icon) to be the rightmost entry in the jump bar, I have to click on the whitespace above my methods.

Reference on PHP net:

http://php.net/manual/en/info.configuration.php#ini.max-input-vars

Please note, you cannot set this directive in run-time with function ini_set(name, newValue), e.g.

ini_set('max_input_vars', 3000);

It will not work.

As explained in documentation, this directive may only be set per directory scope, which means via .htaccess file, httpd.conf or .user.ini (since PHP 5.3).

See http://php.net/manual/en/configuration.changes.modes.php

Adding the directive into php.ini or placing following lines into .htaccess will work:

php_value max_input_vars 3000
php_value suhosin.get.max_vars 3000
php_value suhosin.post.max_vars 3000
php_value suhosin.request.max_vars 3000

according to this link: http://www.authorcode.com/how-to-check-file-permission-to-write-in-c/

it's easier to use existing class SecurityManager

string FileLocation = @"C:\test.txt";
FileIOPermission writePermission = new FileIOPermission(FileIOPermissionAccess.Write, FileLocation);
if (SecurityManager.IsGranted(writePermission))
{
  // you have permission
}
else
{
 // permission is required!
}

but it seems it's been obsoleted, it is suggested to use PermissionSet instead.

[Obsolete("IsGranted is obsolete and will be removed in a future release of the .NET Framework.  Please use the PermissionSet property of either AppDomain or Assembly instead.")]

I was able to solve this problem by cleaning my build.

Top menu -> Product -> Clean Or keyboard shortcut: Shift+Cmd+K

Whenever you encounter an error with this message use my_string.encode().

^{(where my_string is the string you're passing to a function/method).}

The encode method of str objects returns the encoded version of the string as a bytes object which you can then use. In this specific instance, socket methods such as .send expect a bytes object as the data to be sent, not a string object.

Since you have an object of type str and you're passing it to a function/method that expects an object of type bytes, an error is raised that clearly explains that:

TypeError: a bytes-like object is required, not 'str'

So the encode method of strings is needed, applied on a str value and returning a bytes value:

>>> s = "Hello world"
>>> print(type(s))
<class 'str'>
>>> byte_s = s.encode()
>>> print(type(byte_s))
<class 'bytes'>
>>> print(byte_s)
b"Hello world"

Here the prefix b in b'Hello world' denotes that this is indeed a bytes object. You can then pass it to whatever function is expecting it in order for it to run smoothly.

Model-View-Controller

MVC is a pattern for the architecture of a software application. It separate the application logic into three separate parts, promoting modularity and ease of collaboration and reuse. It also makes applications more flexible and welcoming to iterations.It separates an application into the following components:

• Models for handling data and business logic
• Controllers for handling the user interface and application
• Views for handling graphical user interface objects and presentation

To make this a little more clear, let's imagine a simple shopping list app. All we want is a list of the name, quantity and price of each item we need to buy this week. Below we'll describe how we could implement some of this functionality using MVC.

Model-View-Presenter

• The model is the data that will be displayed in the view (user interface).
• The view is an interface that displays data (the model) and routes user commands (events) to the Presenter to act upon that data. The view usually has a reference to its Presenter.
• The Presenter is the “middle-man” (played by the controller in MVC) and has references to both, view and model. Please note that the word “Model” is misleading. It should rather be business logic that retrieves or manipulates a Model. For instance: If you have a database storing User in a database table and your View wants to display a list of users, then the Presenter would have a reference to your database business logic (like a DAO) from where the Presenter will query a list of Users.

If you want to see a sample with simple implementation please check this GitHub post

A concrete workflow of querying and displaying a list of users from a database could work like this:

What is the difference between MVC and MVP patterns?

MVC Pattern

• Controller are based on behaviors and can be shared across views

• Can be responsible for determining which view to display (Front Controller Pattern)

MVP Pattern

• View is more loosely coupled to the model. The presenter is responsible for binding the model to the view.

• Easier to unit test because interaction with the view is through an interface

• Usually view to presenter map one to one. Complex views may have multi presenters.

The algorithm to go from infix to prefix expressions is:

-reverse input

TOS = top of stack
If next symbol is:
 - an operand -> output it
 - an operator ->
        while TOS is an operator of higher priority -> pop and output TOS
        push symbol
 - a closing parenthesis -> push it
 - an opening parenthesis -> pop and output TOS until TOS is matching
        parenthesis, then pop and discard TOS.

-reverse output

So your example goes something like (x PUSH, o POP):

2*3/(2-1)+5*(4-1)
)1-4(*5+)1-2(/3*2

Next
Symbol  Stack           Output
)       x )
1         )             1
-       x )-            1
4         )-            14
(       o )             14-
        o               14-
*       x *             14-
5         *             14-5
+       o               14-5*

2         +)-           14-5*12
(       o +)            14-5*12-
        o +             14-5*12-
/       x +/            14-5*12-

I do understand, that your question was about files stored in MEDIA_ROOT, but sometimes it can be possible to store content in static, when you are not planning to create content of that type anymore.
May be this is a rare case, but anyway - if you have a huge amount of "pictures of the day" for your site - and all these files are on your hard drive?

In that case I see no contra to store such a content in STATIC.
And all becomes really simple:

static

To link to static files that are saved in STATIC_ROOT Django ships with a static template tag. You can use this regardless if you're using RequestContext or not.

{% load static %} <img src="{% static "images/hi.jpg" %}" alt="Hi!" />

copied from Official django 1.4 documentation / Built-in template tags and filters

You can use below code for multiple select:

<select asp-for="EmployeeId"  multiple="multiple" asp-items="@ViewBag.Employees">
    <option>Please select</option>
</select>

You can also use:

<select id="EmployeeId" name="EmployeeId"  multiple="multiple" asp-items="@ViewBag.Employees">
    <option>Please select</option>
</select>

p = subprocess.Popen(cmd, stdout=subprocess.PIPE, shell=True)
p.kill()

p.kill() ends up killing the shell process and cmd is still running.

I found a convenient fix this by:

p = subprocess.Popen("exec " + cmd, stdout=subprocess.PIPE, shell=True)

This will cause cmd to inherit the shell process, instead of having the shell launch a child process, which does not get killed. p.pid will be the id of your cmd process then.

p.kill() should work.

I don't know what effect this will have on your pipe though.

Old post, but I just ran into a very similar problem. After some experimenting, I found that you can do this with a single command:

kill $(ps aux | grep <process_name> | grep -v "grep" | cut -d " " -f2)

In OP's case, <process_name> would be "gedit file.txt".

This is what worked for me (Intellij Idea 2018.1.2):

1) Navigate to: File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle

2) Gradle JVM: change to version 1.8

3) Re-run the gradle task

I made a little helper for Entity Framework 6 (.Net Core style), to include sub-entities in a nice way.

It is on NuGet now : Install-Package ThenInclude.EF6

using System.Data.Entity;

var thenInclude = context.One.Include(x => x.Twoes)
    .ThenInclude(x=> x.Threes)
    .ThenInclude(x=> x.Fours)
    .ThenInclude(x=> x.Fives)
    .ThenInclude(x => x.Sixes)
    .Include(x=> x.Other)
    .ToList();

The package is available on GitHub.

For changing data type

alter table table_name 
alter column column_name datatype [NULL|NOT NULL]

For changing Primary key

ALTER TABLE table_name  
ADD CONSTRAINT PK_MyTable PRIMARY KEY (column_name)

I had the URL from run time, below gave the correct answer:

let url = "www.site.com/index.php#hello";
alert(url.split('#')[1]);

hope this helps

You still have to wrap it in an ISERROR, but you could use MATCH() instead of VLOOKUP():

Returns the relative position of an item in an array that matches a specified value in a specified order. Use MATCH instead of one of the LOOKUP functions when you need the position of an item in a range instead of the item itself.

Here's a complete example, assuming you're looking for the word "key" in a range of cells:

=IF(ISERROR(MATCH("key",A5:A16,FALSE)),"missing","found")

The FALSE is necessary to force an exact match, otherwise it will look for the closest value.

You've seen this example on Google Code's issue page and (only recently) on Stack Overflow's edit page.

CMS's answer doesn't revert the positioning when you scroll back up. Here's the shamelessly stolen code from Stack Overflow:

function moveScroller() {
    var $anchor = $("#scroller-anchor");
    var $scroller = $('#scroller');

    var move = function() {
        var st = $(window).scrollTop();
        var ot = $anchor.offset().top;
        if(st > ot) {
            $scroller.css({
                position: "fixed",
                top: "0px"
            });
        } else {
            $scroller.css({
                position: "relative",
                top: ""
            });
        }
    };
    $(window).scroll(move);
    move();
}

<div id="sidebar" style="width:270px;"> 
  <div id="scroller-anchor"></div> 
  <div id="scroller" style="margin-top:10px; width:270px"> 
    Scroller Scroller Scroller
  </div>
</div>

<script type="text/javascript"> 
  $(function() {
    moveScroller();
  });
</script> 

And a simple live demo.

A nascent, script-free alternative is position: sticky, which is supported in Chrome, Firefox, and Safari. See the article on HTML5Rocks and demo, and Mozilla docs.

1) Declare menu in your class.

private Menu menu;

2) In onCreateOptionsMenu do the following :

public boolean onCreateOptionsMenu(Menu menu) {
    this.menu = menu;
    getMenuInflater().inflate(R.menu.menu_orders_screen, menu);
    return true;
}   

3) In onOptionsItemSelected, get the item and do the changes as required(icon, text, colour, background)

public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if (id == R.id.action_search) {
        return true;
    }
    if (id == R.id.ventor_status) {
        return true;
    }
    if (id == R.id.action_settings_online) {
        menu.getItem(0).setIcon(getResources().getDrawable(R.drawable.history_converted));
        menu.getItem(1).setTitle("Online");
        return true;
    }
    if (id == R.id.action_settings_offline) {
        menu.getItem(0).setIcon(getResources().getDrawable(R.drawable.cross));
        menu.getItem(1).setTitle("Offline");
        return true;
    }

    return super.onOptionsItemSelected(item);
}

Note:
If you have 3 menu items :
menu.getItem(0) = 1 item,
menu.getItem(1) = 2 iteam,
menu.getItem(2) = 3 item

Based on this make the changes accordingly as per your requirement.

The server should respond with the correct MIME Type for JSONP application/javascript and your request should tell jQuery you are loading JSONP dataType: 'jsonp'

Please see this answer for further details ! You can also have a look a this one as it explains why loading .js file with text/plain won't work.

I figured out another way that works with most istreams, including std::cin!

std::string readFile()
{
    stringstream str;
    ifstream stream("Hello_World.txt");
    if(stream.is_open())
    {
        while(stream.peek() != EOF)
        {
            str << (char) stream.get();
        }
        stream.close();
        return str.str();
    }
}

This is how I solved the problem. Add below code in your AndroidMainfest.xml

<activity android:name=".YourClass"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar">
 </activity>

A .pl is a single script.

In .pm (Perl Module) you have functions that you can use from other Perl scripts:

A Perl module is a self-contained piece of Perl code that can be used by a Perl program or by other Perl modules. It is conceptually similar to a C link library, or a C++ class.

You can check string equal to null using this:

String Test = null;
(Test+"").compareTo("null")

If the result is 0 then (Test+"") = "null".

Any of these solution will work regarding your question:

INSERT IGNORE INTO table (id, name, age) VALUES (1, "A", 19);

or

INSERT INTO TABLE (id, name, age) VALUES(1, "A", 19) 
    ON DUPLICATE KEY UPDATE NAME = "A", AGE = 19;  

or

REPLACE INTO table (id, name, age) VALUES(1, "A", 19);

If you want to know in details regarding these statement visit this link

Use the following code in your CSS

html { _x000D_
  background: url(images/bg.jpg) no-repeat center center fixed; _x000D_
  -webkit-background-size: cover;_x000D_
  -moz-background-size: cover;_x000D_
  -o-background-size: cover;_x000D_
  background-size: cover;_x000D_
}

Here my analysis of the @Greg answer: componentsprogramming.com/palindromes

Sidenote: But, for me it is important to do it in a Generic way. The requirements are that the sequence is bidirectionally iterable and the elements of the sequence are comparables using equality. I don't know how to do it in Java, but, here is a C++ version, I don't know a better way to do it for bidirectional sequences.

template <BidirectionalIterator I> 
    requires( EqualityComparable< ValueType<I> > ) 
bool palindrome( I first, I last ) 
{ 
    I m = middle(first, last); 
    auto rfirst = boost::make_reverse_iterator(last); 
    return std::equal(first, m, rfirst); 
} 

Complexity: linear-time,

• If I is RandomAccessIterator: floor(n/2) comparissons and floor(n/2)*2 iterations

• If I is BidirectionalIterator: floor(n/2) comparissons and floor(n/2)*2 iterations plus (3/2)*n iterations to find the middle ( middle function )

• storage: O(1)

• No dymamic allocated memory

You could do something like this for your case - (syntax may be a bit off). Also look at this link

subQuery = (from crtu in CompanyRolesToUsers where crtu.RoleId==2 || crtu.RoleId==3 select crtu.UserId).ToArrayList();

finalQuery = from u in Users where u.LastName.Contains('fra')  && subQuery.Contains(u.Id) select u;

When you are trying to prevent XSS, it's important to think of the context. As an example how and what to escape is very different if you are ouputting data inside a variable in a javascript snippet as opposed to outputting data in an HTML tag or an HTML attribute.

I have an example of this here: http://erlend.oftedal.no/blog/?blogid=91

Also checkout the OWASP XSS Prevention Cheat Sheet: http://www.owasp.org/index.php/XSS_%28Cross_Site_Scripting%29_Prevention_Cheat_Sheet

So the short answer is, make sure you escape output like suggested by Tendayi Mawushe, but take special care when you are outputting data in HTML attributes or javascript.

You could look for the presence of a map key or see if it's in a set.

Depending on what you're actually doing, though, you might be trying to solve the problem wrong :)

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/foobar/i$ index.php [NE,L]

null is special value, it is not instance of anything. For obviously reason it cannot be instanceof anything.

With ECMAScript 2015 you are now able to do it directly in object declaration with the brackets notation: 

var obj = {
  [key]: value
}

Where key can be any sort of expression (e.g. a variable) returning a value.

So here your code would look like:

<something>.stop().animate({
  [thetop]: 10
}, 10)

Where thetop will be evaluated before being used as key.

Here's one way to do this through the console:

>> foo = ActionView::Base.new
=> #<ActionView::Base:0x2aaab0ac2af8 @assigns_added=nil, @assigns={}, @helpers=#<ActionView::Base::ProxyModule:0x2aaab0ac2a58>, @controller=nil, @view_paths=[]>

>> foo.extend YourHelperModule
=> #<ActionView::Base:0x2aaab0ac2af8 @assigns_added=nil, @assigns={}, @helpers=#<ActionView::Base::ProxyModule:0x2aaab0ac2a58>, @controller=nil, @view_paths=[]>

>> foo.your_helper_method(args)
=> "<html>created by your helper</html>"

Creating a new instance of ActionView::Base gives you access to the normal view methods that your helper likely uses. Then extending YourHelperModule mixes its methods into your object letting you view their return values.

To expand one what CheeseConQueso is saying, here are the entire steps to update a view using PHPMyAdmin:

1. Run the following query: SHOW CREATE VIEW your_view_name
2. Expand the options and choose Full Texts
3. Press Go
4. Copy entire contents of the Create View column.
5. Make changes to the query in the editor of your choice
6. Run the query directly (without the CREATE VIEW... syntax) to make sure it runs as you expect it to.
7. Once you're satisfied, click on your view in the list on the left to browse its data and then scroll all the way to the bottom where you'll see a CREATE VIEW link. Click that.
8. Place a check in the OR REPLACE field.
9. In the VIEW name put the name of the view you are going to update.
10. In the AS field put the contents of the query that you ran while testing (without the CREATE VIEW... syntax).
11. Press Go

I hope that helps somebody. Special thanks to CheesConQueso for his/her insightful answer.

What it is:

%0|%0 is a fork bomb. It will spawn another process using a pipe | which runs a copy of the same program asynchronously. This hogs the CPU and memory, slowing down the system to a near-halt (or even crash the system).

How this works:

%0 refers to the command used to run the current program. For example, script.bat

A pipe | symbol will make the output or result of the first command sequence as the input for the second command sequence. In the case of a fork bomb, there is no output, so it will simply run the second command sequence without any input.

Expanding the example, %0|%0 could mean script.bat|script.bat. This runs itself again, but also creating another process to run the same program again (with no input).

If you are using sass as style preprocessor, you can switch back to native Sass compiler for dev dependency by:

npm install node-sass --save-dev

So that you can keep using /deep/ for development.

Even though this post is outdated, collection.remove is deprecated! collection.delete_one should be used instead!

According to PHPMailer Manual, full answer would be :

$mail->AddEmbeddedImage(filename, cid, name);
//Example
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg '); 

Use Case :

$mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
$mail->Body = 'Embedded Image: <img alt="PHPMailer" src="cid:my-attach"> Here is an image!';

If you want to display an image with a remote URL :

$mail->addStringAttachment(file_get_contents("url"), "filename");

You might want to check out RFC 6570. This URI Template spec shows many examples of how urls can contain parameters.

This solved it for me

AppRegistry.registerComponent('main', () => App);

So my index.js file

import { AppRegistry } from 'react-native';
import App from './App';
AppRegistry.registerComponent('main', () => App);

And my package.json file:

"dependencies": {
    "react": "^16.13.1",
    "react-dom": "~16.9.0",
    "react-native": "~0.61.5"
},

These do the same thing:

window.location.assign(url);
window.location = url;
window.location.href = url;

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

So, what you have read in those many forums is not correct. The assign method does add a new record to the history.

this worked for me. to pass an array of Item object {ItemID,ColorID,SizeID,Quntity}

dates_dict[key] = dates_dict.get(key, []).append(date) sets dates_dict[key] to None as list.append returns None.

In [5]: l = [1,2,3]

In [6]: var = l.append(3)

In [7]: print var
None

You should use collections.defaultdict

import collections
dates_dict = collections.defaultdict(list)

You can try using:

textBox.ReadOnly = true;
textBox.BackColor = System.Drawing.SystemColors.Window;

The last line is only neccessary if you want a non-grey background color.

To concatenate multiple strings into a single string, separated by another character, there are a couple of ways.

The nicest I have seen is using the join method on an array:

fn main() {
    let a = "Hello";
    let b = "world";
    let result = [a, b].join("\n");

    print!("{}", result);
}

Depending on your use case you might also prefer more control:

fn main() {
    let a = "Hello";
    let b = "world";
    let result = format!("{}\n{}", a, b);

    print!("{}", result);
}

There are some more manual ways I have seen, some avoiding one or two allocations here and there. For readability purposes I find the above two to be sufficient.

If you want to fill NaN for a specific column you can use loc:

d1 = {"Col1" : ['A', 'B', 'C'],
     "fruits": ['Avocado', 'Banana', 'NaN']}
d1= pd.DataFrame(d1)

output:

Col1    fruits
0   A   Avocado
1   B   Banana
2   C   NaN


d1.loc[ d1.Col1=='C', 'fruits' ] =  'Carrot'


output:

Col1    fruits
0   A   Avocado
1   B   Banana
2   C   Carrot

i dont know exactly about the greedy issue, but try this if it works for you:

public boolean like(final String str, String expr)
  {
    final String[] parts = expr.split("%");
    final boolean traillingOp = expr.endsWith("%");
    expr = "";
    for (int i = 0, l = parts.length; i < l; ++i)
    {
      final String[] p = parts[i].split("\\\\\\?");
      if (p.length > 1)
      {
        for (int y = 0, l2 = p.length; y < l2; ++y)
        {
          expr += p[y];
          if (i + 1 < l2) expr += ".";
        }
      }
      else
      {
        expr += parts[i];
      }
      if (i + 1 < l) expr += "%";
    }
    if (traillingOp) expr += "%";
    expr = expr.replace("?", ".");
    expr = expr.replace("%", ".*");
    return str.matches(expr);
}

I found no solid answers that didn't either break accessibility or subvert functionality.

Perhaps combining a few will work better overall.

<h1
  onmousedown="this.style.outline='none';"
  onclick="this.blur(); runFn(this);"
  onmouseup="this.style.outline=null;"
>Hello</h1>

function runFn(thisElem) { console.log('Hello: ', thisElem); }

ul { 
     /* Remove default list icon */
     list-style:  none;
     padding:  0;

     /* Small width and margin to demonstrate the text wrapping */
     width: 200px;
     border:1px solid red;
}

li{
   /* Make sure the text is properly wrpped (not spilling in the image area) */ 
    display: flex;
}

li:before {
     content:  url(https://via.placeholder.com/10/0000FF/808080/?text=*);
     display:  inline-block;
     vertical-align:  middle;

     /* If you want some space between icon and text: */
     margin-right:   2em;
}

well, there are many ways to do this in javascript just like other says. I don't think there's a way to do it in react. here's what I would do:

in a js file:

module.exports = {
    small_square: 's',
    large_square: 'q'
}

in your react file:

'use strict';

var Constant = require('constants');
....
var something = Constant.small_square;

something for you to consider, hope this helps

I know it's way way overdue, but I have an alternative solution, which is lighter and simpler. Derive a class from System.Windows.Controls.RadioButton and declare two dependency properties RadioValue and RadioBinding. Then in the class code, override OnChecked and set the RadioBinding property value to that of the RadioValue property value. In the other direction, trap changes to the RadioBinding property using a callback, and if the new value is equal to the value of the RadioValue property, set its IsChecked property to true.

Here's the code:

public class MyRadioButton : RadioButton
{
    public object RadioValue
    {
        get { return (object)GetValue(RadioValueProperty); }
        set { SetValue(RadioValueProperty, value); }
    }

    // Using a DependencyProperty as the backing store for RadioValue.
       This enables animation, styling, binding, etc...
    public static readonly DependencyProperty RadioValueProperty =
        DependencyProperty.Register(
            "RadioValue", 
            typeof(object), 
            typeof(MyRadioButton), 
            new UIPropertyMetadata(null));

    public object RadioBinding
    {
        get { return (object)GetValue(RadioBindingProperty); }
        set { SetValue(RadioBindingProperty, value); }
    }

    // Using a DependencyProperty as the backing store for RadioBinding.
       This enables animation, styling, binding, etc...
    public static readonly DependencyProperty RadioBindingProperty =
        DependencyProperty.Register(
            "RadioBinding", 
            typeof(object), 
            typeof(MyRadioButton), 
            new FrameworkPropertyMetadata(
                null, 
                FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, 
                OnRadioBindingChanged));

    private static void OnRadioBindingChanged(
        DependencyObject d,
        DependencyPropertyChangedEventArgs e)
    {
        MyRadioButton rb = (MyRadioButton)d;
        if (rb.RadioValue.Equals(e.NewValue))
            rb.SetCurrentValue(RadioButton.IsCheckedProperty, true);
    }

    protected override void OnChecked(RoutedEventArgs e)
    {
        base.OnChecked(e);
        SetCurrentValue(RadioBindingProperty, RadioValue);
    }
}

XAML usage:

<my:MyRadioButton GroupName="grp1" Content="Value 1"
    RadioValue="val1" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 2"
    RadioValue="val2" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 3"
    RadioValue="val3" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 4"
    RadioValue="val4" RadioBinding="{Binding SelectedValue}"/>

Hope someone finds this useful after all this time :)

I had this issue with MacOS High Sierria.

You can set up locale as well as language to UTF-8 format using below command :

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8

Now in order to check whether locale environment is updated use below command :

Locale

If you want to check contents are equal or not then just use JSON.stringify(obj)

Eg - var a ={key:val};

var b ={key:val};

JSON.stringify(a) == JSON.stringify(b) -----> If contents are same you gets true.

You have by default the static endpoint for static files. Also Flask application has the following arguments:

static_url_path: can be used to specify a different path for the static files on the web. Defaults to the name of the static_folder folder.

static_folder: the folder with static files that should be served at static_url_path. Defaults to the 'static' folder in the root path of the application.

It means that the filename argument will take a relative path to your file in static_folder and convert it to a relative path combined with static_url_default:

url_for('static', filename='path/to/file')

will convert the file path from static_folder/path/to/file to the url path static_url_default/path/to/file.

So if you want to get files from the static/bootstrap folder you use this code:

<link rel="stylesheet" type="text/css" href="{{ url_for('static', filename='bootstrap/bootstrap.min.css') }}">

Which will be converted to (using default settings):

<link rel="stylesheet" type="text/css" href="static/bootstrap/bootstrap.min.css">

Also look at url_for documentation.

I had the same issue, but I found a good solution here: Stop caching for PHP 5.5.3 in MAMP

Basically find the php.ini file and comment out the OPCache lines. I hope this alternative answer helps others else out as well.

Workaround:

template<class T, size_t N>
struct simple_array { // like std::array in C++0x
   T arr[N];
};


class C : private simple_array<int, 3> 
{
      static simple_array<int, 3> myarr() {
           simple_array<int, 3> arr = {1,2,3};
           return arr;
      }
public:
      C() : simple_array<int, 3>(myarr()) {}
};

A stream is an object used to transfer data. There is a generic stream class System.IO.Stream, from which all other stream classes in .NET are derived. The Stream class deals with bytes.

The concrete stream classes are used to deal with other types of data than bytes. For example:

• The FileStream class is used when the outside source is a file
• MemoryStream is used to store data in memory
• System.Net.Sockets.NetworkStream handles network data

Reader/writer streams such as StreamReader and StreamWriter are not streams - they are not derived from System.IO.Stream, they are designed to help to write and read data from and to stream!

To accomplish the same thing as:

svn st | awk '{print $2}' | xargs rm

using only bash you can use:

svn st | while read a b; do rm "$b"; done

Granted, it's not shorter, but it's a bit more efficient and it handles whitespace in your filenames correctly.

Hash's key? method tells you whether a given key is present or not.

session.key?("user")

Can brackets be nested?

If not: \[([^]]+)\] matches one item, including square brackets. Backreference \1 will contain the item to be match. If your regex flavor supports lookaround, use

(?<=\[)[^]]+(?=\])

This will only match the item inside brackets.

It's just the syntax. '<' is a binary operation, and most languages don't make it transitive. They could have made it like the way you say, but then somebody would be asking why you can't do other operations in trinary as well. "if (12 < x != 5)"?

Syntax is always a trade-off between complexity, expressiveness and readability. Different language designers make different choices. For instance, SQL has "x BETWEEN y AND z", where x, y, and z can individually or all be columns, constants, or bound variables. And I'm happy to use it in SQL, and I'm equally happy not to worry about why it's not in Java.

You'd need to use return values.

DECLARE @SelectedValue int

CREATE PROCEDURE GetMyInt (@MyIntField int OUTPUT)
AS
SELECT @MyIntField = MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1

Then you call it like this:

EXEC GetMyInt OUTPUT @SelectedValue

Simply paste the following code in your web.config file.

Noted that, you have to paste the following code under <system.webServer> tag

    <httpProtocol>  
    <customHeaders>  
     <add name="Access-Control-Allow-Origin" value="*" />  
     <add name="Access-Control-Allow-Headers" value="Content-Type" />  
     <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />  
    </customHeaders>  
  </httpProtocol>  

Using dplyr:

require(dplyr)    
df <- data.frame(A = c(1, 1, 2, 3, 3), B = c(2, 3, 3, 5, 6))
df %>% group_by(A) %>% summarise(B = sum(B))

## Source: local data frame [3 x 2]
## 
##   A  B
## 1 1  5
## 2 2  3
## 3 3 11

With sqldf:

library(sqldf)
sqldf('SELECT A, SUM(B) AS B FROM df GROUP BY A')

You can simply use the following (I know there are shorter ways to do this, but this may make it easier to visually observe, at least for others looking at the code).

if (x === null || x === undefined) {
 // Add your response code here, etc.
}

Give this a go:

<option onclick="parent.location='#5.2'">Bookmark 2</option>

Note: These are estimates, made more accurate with gather statistics:

exec dbms_utility.analyze_schema(user,'COMPUTE');

ES5 compatible native one-liner:

var merged = [obj1, obj2].reduce(function(a, o) { for(k in o) a[k] = o[k]; return a; }, {})

One thing not clearly covered is that microsoft sql is creating in the background an unique index for the added constraint

create table Customer ( id int primary key identity (1,1) , name nvarchar(128) ) 

--Commands completed successfully.

sp_help Customer

---> index
--index_name    index_description   index_keys
--PK__Customer__3213E83FCC4A1DFA    clustered, unique, primary key located on PRIMARY   id

---> constraint

--PRIMARY KEY (clustered)   PK__Customer__3213E83FCC4A1DFA  (n/a)   (n/a)   (n/a)   (n/a)   id


---- now adding the unique constraint

ALTER TABLE Customer ADD CONSTRAINT U_Name UNIQUE(Name)

-- Commands completed successfully.

sp_help Customer

---UNIQUE (non-clustered)   U_Name  (n/a)   (n/a)   (n/a)   (n/a)   name

as you can see , there is a new constraint and a new index U_Name

I created a DefaultableDictionary to do exactly what you are asking for!

using System;
using System.Collections;
using System.Collections.Generic;
using System.Collections.ObjectModel;

namespace DefaultableDictionary {
    public class DefaultableDictionary<TKey, TValue> : IDictionary<TKey, TValue> {
        private readonly IDictionary<TKey, TValue> dictionary;
        private readonly TValue defaultValue;

        public DefaultableDictionary(IDictionary<TKey, TValue> dictionary, TValue defaultValue) {
            this.dictionary = dictionary;
            this.defaultValue = defaultValue;
        }

        public IEnumerator<KeyValuePair<TKey, TValue>> GetEnumerator() {
            return dictionary.GetEnumerator();
        }

        IEnumerator IEnumerable.GetEnumerator() {
            return GetEnumerator();
        }

        public void Add(KeyValuePair<TKey, TValue> item) {
            dictionary.Add(item);
        }

        public void Clear() {
            dictionary.Clear();
        }

        public bool Contains(KeyValuePair<TKey, TValue> item) {
            return dictionary.Contains(item);
        }

        public void CopyTo(KeyValuePair<TKey, TValue>[] array, int arrayIndex) {
            dictionary.CopyTo(array, arrayIndex);
        }

        public bool Remove(KeyValuePair<TKey, TValue> item) {
            return dictionary.Remove(item);
        }

        public int Count {
            get { return dictionary.Count; }
        }

        public bool IsReadOnly {
            get { return dictionary.IsReadOnly; }
        }

        public bool ContainsKey(TKey key) {
            return dictionary.ContainsKey(key);
        }

        public void Add(TKey key, TValue value) {
            dictionary.Add(key, value);
        }

        public bool Remove(TKey key) {
            return dictionary.Remove(key);
        }

        public bool TryGetValue(TKey key, out TValue value) {
            if (!dictionary.TryGetValue(key, out value)) {
                value = defaultValue;
            }

            return true;
        }

        public TValue this[TKey key] {
            get
            {
                try
                {
                    return dictionary[key];
                } catch (KeyNotFoundException) {
                    return defaultValue;
                }
            }

            set { dictionary[key] = value; }
        }

        public ICollection<TKey> Keys {
            get { return dictionary.Keys; }
        }

        public ICollection<TValue> Values {
            get
            {
                var values = new List<TValue>(dictionary.Values) {
                    defaultValue
                };
                return values;
            }
        }
    }

    public static class DefaultableDictionaryExtensions {
        public static IDictionary<TKey, TValue> WithDefaultValue<TValue, TKey>(this IDictionary<TKey, TValue> dictionary, TValue defaultValue ) {
            return new DefaultableDictionary<TKey, TValue>(dictionary, defaultValue);
        }
    }
}

This project is a simple decorator for an IDictionary object and an extension method to make it easy to use.

The DefaultableDictionary will allow for creating a wrapper around a dictionary that provides a default value when trying to access a key that does not exist or enumerating through all the values in an IDictionary.

Example: var dictionary = new Dictionary<string, int>().WithDefaultValue(5);

Blog post on the usage as well.

InstallUtil classes ( ServiceInstaller ) are considered an anti-pattern by the Windows Installer community. It's a fragile, out of process, reinventing of the wheel that ignores the fact that Windows Installer has built-in support for Services.

Visual Studio deployment projects ( also not highly regarded and deprecated in the next release of Visual Studio ) do not have native support for services. But they can consume merge modules. So I would take a look at this blog article to understand how to create a merge module using Windows Installer XML that can express the service and then consume that merge module in your VDPROJ solution.

For the most part, the number of bytes and range of values is determined by the CPU's architecture not by C++. However, C++ sets minimum requirements, which litb explained properly and Martin York only made a few mistakes with.

The reason why you can't use int and long interchangeably is because they aren't always the same length. C was invented on a PDP-11 where a byte had 8 bits, int was two bytes and could be handled directly by hardware instructions. Since C programmers often needed four-byte arithmetic, long was invented and it was four bytes, handled by library functions. Other machines had different specifications. The C standard imposed some minimum requirements.

Regular javascript can be used to trap the backspace key. You can use the event.keyCode method. The keycode is 8, so the code would look something like this:

if (event.keyCode == 8) {
    // Do stuff...
}

If you want to check for both the [delete] (46) as well as the [backspace] (8) keys, use the following:

if (event.keyCode == 8 || event.keyCode == 46) {
    // Do stuff...
}

1. When you don't want to keep your local changes at all.

git reset --hard

This command will completely remove all the local changes from your local repository. This is the best way to avoid conflicts during pull command, only if you don't want to keep your local changes at all.

2. When you want to keep your local changes

If you want to pull the new changes from remote and want to ignore the local changes during this pull then,

git stash

It will stash all the local changes, now you can pull the remote changes,

git pull

Now, you can bring back your local changes by,

git stash pop

You can do the HTML parsing but it is not at all recommended instead ask the website owners to provide web services then you can parse that information.

JSON_UNESCAPED_UNICODE was added in PHP 5.4 so it looks like you need upgrade your version of PHP to take advantage of it. 5.4 is not released yet though! :(

There is a 5.4 alpha release candidate on QA though if you want to play on your development machine.

Have you tried this: create a Computed column, called 'Expiry', with a formula that amounts to '[Created] + 7 days'. Then use the computed column in your View's filter. Let us know whether this worked or what problems this poses!

Another possibility is to use separate lines to set up Make variables when a rule fires.

For example, here is a makefile with two rules. If a rule fires, it creates a temp dir and sets TMP to the temp dir name.

PHONY = ruleA ruleB display

all: ruleA

ruleA: TMP = $(shell mktemp -d testruleA_XXXX)
ruleA: display

ruleB: TMP = $(shell mktemp -d testruleB_XXXX)
ruleB: display

display:
    echo ${TMP}

Running the code produces the expected result:

$ ls
Makefile
$ make ruleB
echo testruleB_Y4Ow
testruleB_Y4Ow
$ ls
Makefile  testruleB_Y4Ow

You might try boost::lexical_cast. It throws an bad_lexical_cast exception if it fails.

In your case:

int number;
try
{
  number = boost::lexical_cast<int>(word);
}
catch(boost::bad_lexical_cast& e)
{
  std::cout << word << "isn't a number" << std::endl;
}

impossible with javascript. Just as another alternative to suggestions from other answers: consider using jGrowl: http://archive.plugins.jquery.com/project/jGrowl

I was having a similar problem that I could not resolve for a long time on my new server. In addition to palacsint's answer, a good question to ask is: are you using Apache 2.4? In Apache 2.4 there is a different mechanism for setting the permissions that do not work when done using the above configuration, so I used the solution explained in this blog post.

Basically, what I needed to do was convert my config file from:

Alias /demo /usr/demo/html

<Directory "/usr/demo/html">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    allow from all

</Directory>

to:

Alias /demo /usr/demo/html

<Directory "/usr/demo/html">
    Options FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

Note how the Order and allow lines have been replaced by Require all granted

If you are on an AWS EC2 instance running an Ubuntu instance (tested on Ubuntu 16.x), then these steps might work for you:

    sudo apt-get update
    sudo apt-get --purge remove node -y
    sudo apt-get --purge remove nodejs -y
    sudo apt-get --purge remove legacy-node -y
    sudo rm  /usr/bin/node
    curl -sL https://deb.nodesource.com/setup_6.x | sudo bash -
    sudo apt-get install nodejs -y
    node -v

If all is correct the last command shall have an output like : v6.x.x

If not then run the following:

    sudo ln -s /usr/bin/nodejs /usr/bin/node

Hopefully this will help. It helped me magically (hehe).

If you don't know which extension you have, then you can try this:

$ext = strtolower(substr('yourFileName.ext', strrpos('yourFileName.ext', '.') + 1));
echo basename('yourFileName.ext','.'.$ext); // output: "youFileName" only

Working with all possibilities:

image.jpg // output: "image"
filename.image.png // output: "filename.image"
index.php // output: "index"

This is an issue relating JRE.In my case (eclipse Luna with Maven plugin, JDK 7) I solved this by making following change in pom.xml and then Maven Update Project.

from:

 <configuration>
        <source>1.8</source>
        <target>1.8</target>
</configuration>

to:

 <configuration>
        <source>1.7</source>
        <target>1.7</target>
</configuration>

For those who use Github, they have a branch network viewer that seems easier to read

I tried the callback way and could not get this to work, what you have to understand is that values are still atomic even though execution is not. For example:

alert('1'); <--- these two functions will be executed at the same time

alert('2'); <--- these two functions will be executed at the same time

but doing like this will force us to know the order of execution:

loop=2;
total=0;
for(i=0;i<loop;i++) {
           total+=1;
           if(total == loop)
                      alert('2');
           else
                      alert('1');
}

If you just need to read the data.

encrypt(str.data(),str.size());

If you need a read/write copy of the data put it into a vector. (Don;t dynamically allocate space that's the job of vector).

std::vector<byte>  source(str.begin(),str.end());
encrypt(&source[0],source.size());

Of course we are all assuming that byte is a char!!!

Since it's a POD struct, you could always memset it to 0 - this might be the easiest way to get the fields initialized (assuming that is appropriate).

It should be:

$when(((tdata.Age == "" ) & (tdata.Survived == "0")), mean_age_0)

Another way of solving this is to use the DictReader class, which "skips" the header row and uses it to allowed named indexing.

Given "foo.csv" as follows:

FirstColumn,SecondColumn
asdf,1234
qwer,5678

Use DictReader like this:

import csv
with open('foo.csv') as f:
    reader = csv.DictReader(f, delimiter=',')
    for row in reader:
        print(row['FirstColumn'])  # Access by column header instead of column number
        print(row['SecondColumn'])

Save:

public boolean saveFile(Context context, String mytext){
    Log.i("TESTE", "SAVE");
    try {
        FileOutputStream fos = context.openFileOutput("file_name"+".txt",Context.MODE_PRIVATE);
        Writer out = new OutputStreamWriter(fos);
        out.write(mytext);
        out.close();
        return true;
    } catch (IOException e) {
        e.printStackTrace();
        return false;
    }
}

Load:

public String load(Context context){
    Log.i("TESTE", "FILE");
    try {
        FileInputStream fis = context.openFileInput("file_name"+".txt");
        BufferedReader r = new BufferedReader(new InputStreamReader(fis));
        String line= r.readLine();
        r.close();
        return line;
    } catch (IOException e) {
        e.printStackTrace();
        Log.i("TESTE", "FILE - false");
        return null;
    }
}

i would recommend using this:

  background-repeat:no-repeat;
  background-image: url(your file location here);
  background-size:cover;(will only work with css3)

hope it helps :D

And if this doesnt support your needs just say it: i can make a jquery for multibrowser support.

You can not count nulls (at least not in Oracle). Instead try this

SELECT count(1) FROM TABLE WHERE COL_NAME IS NULL

If for some reason you don't want to use the break instruction (if you think it will disrupt your reading flow next time you will read your programm, for example), you can try the following :

boolean test = true;
for (int i = 0; i < 1220 && test; i++) {
    System.out.println(i);
    if (i == 20) {
        test = false;
    }
 }

The second arg of a for loop is a boolean test. If the result of the test is true, the loop will stop. You can use more than just an simple math test if you like. Otherwise, a simple break will also do the trick, as others said :

for (int i = 0; i < 1220 ; i++) {
    System.out.println(i);
    if (i == 20) {
        break;
    }
 }

Calling axvline in a loop, as others have suggested, works, but can be inconvenient because

1. Each line is a separate plot object, which causes things to be very slow when you have many lines.
2. When you create the legend each line has a new entry, which may not be what you want.

Instead you can use the following convenience functions which create all the lines as a single plot object:

import matplotlib.pyplot as plt
import numpy as np


def axhlines(ys, ax=None, lims=None, **plot_kwargs):
    """
    Draw horizontal lines across plot
    :param ys: A scalar, list, or 1D array of vertical offsets
    :param ax: The axis (or none to use gca)
    :param lims: Optionally the (xmin, xmax) of the lines
    :param plot_kwargs: Keyword arguments to be passed to plot
    :return: The plot object corresponding to the lines.
    """
    if ax is None:
        ax = plt.gca()
    ys = np.array((ys, ) if np.isscalar(ys) else ys, copy=False)
    if lims is None:
        lims = ax.get_xlim()
    y_points = np.repeat(ys[:, None], repeats=3, axis=1).flatten()
    x_points = np.repeat(np.array(lims + (np.nan, ))[None, :], repeats=len(ys), axis=0).flatten()
    plot = ax.plot(x_points, y_points, scalex = False, **plot_kwargs)
    return plot


def axvlines(xs, ax=None, lims=None, **plot_kwargs):
    """
    Draw vertical lines on plot
    :param xs: A scalar, list, or 1D array of horizontal offsets
    :param ax: The axis (or none to use gca)
    :param lims: Optionally the (ymin, ymax) of the lines
    :param plot_kwargs: Keyword arguments to be passed to plot
    :return: The plot object corresponding to the lines.
    """
    if ax is None:
        ax = plt.gca()
    xs = np.array((xs, ) if np.isscalar(xs) else xs, copy=False)
    if lims is None:
        lims = ax.get_ylim()
    x_points = np.repeat(xs[:, None], repeats=3, axis=1).flatten()
    y_points = np.repeat(np.array(lims + (np.nan, ))[None, :], repeats=len(xs), axis=0).flatten()
    plot = ax.plot(x_points, y_points, scaley = False, **plot_kwargs)
    return plot

The following code (in Kotlin) works from API 21 until at least current API version (API 29). The function getWifiState() returns one of 3 possible values for the WiFi network state: Disable, EnabledNotConnected and Connected that were defined in an enum class. This allows to take more granular decisions like informing the user to enable WiFi or, if already enabled, to connect to one of the available networks. But if all that is needed is a boolean indicating if the WiFi interface is connected to a network, then the other function isWifiConnected() will give you that. It uses the previous one and compares the result to Connected.

It's inspired in some of the previous answers but trying to solve the problems introduced by the evolution of Android API's or the slowly increasing availability of IP V6. The trick was to use:

wifiManager.connectionInfo.bssid != null 

instead of:

1. getIpAddress() == 0 that is only valid for IP V4 or
2. getNetworkId() == -1 that now requires another special permission (Location)

According to the documentation: https://developer.android.com/reference/kotlin/android/net/wifi/WifiInfo.html#getbssid it will return null if not connected to a network. And even if we do not have permission to get the real value, it will still return something other than null if we are connected.

Also have the following in mind:

On releases before android.os.Build.VERSION_CODES#N, this object should only be obtained from an Context#getApplicationContext(), and not from any other derived context to avoid memory leaks within the calling process.

In the Manifest, do not forget to add:

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

Proposed code is:

class MyViewModel(application: Application) : AndroidViewModel(application) {

   // Get application context
    private val myAppContext: Context = getApplication<Application>().applicationContext

   // Define the different possible states for the WiFi Connection
    internal enum class WifiState {
        Disabled,               // WiFi is not enabled
        EnabledNotConnected,    // WiFi is enabled but we are not connected to any WiFi network
        Connected,              // Connected to a WiFi network
    }

    // Get the current state of the WiFi network
    private fun getWifiState() : WifiState {

        val wifiManager : WifiManager = myAppContext.applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager

        return if (wifiManager.isWifiEnabled) {
                    if (wifiManager.connectionInfo.bssid != null)
                        WifiState.Connected
                    else
                        WifiState.EnabledNotConnected
               } else {
                    WifiState.Disabled
               }
    }

    // Returns true if we are connected to a WiFi network
    private fun isWiFiConnected() : Boolean {
        return (getWifiState() == WifiState.Connected)
    }
}

I had the same problem with rails 3.1.0, and I solved adding in file the followings lines:

According to documentation you can use the reverse argument.

filter:orderBy(array, expression[, reverse]);

Change your filter to:

orderBy: 'created_at':true

The subquery option has already been answered, but note that in many cases a LEFT JOIN can be a faster way to do this:

SELECT table1.*
FROM table1 LEFT JOIN table2 ON table2.principal=table1.principal
WHERE table2.principal IS NULL

If you want to check multiple tables to make sure it's not present in any of the tables (like in SRKR's comment), you can use this:

SELECT table1.*
FROM table1
LEFT JOIN table2 ON table2.name=table1.name
LEFT JOIN table3 ON table3.name=table1.name
WHERE table2.name IS NULL AND table3.name IS NULL

In PostgreSQL, you can do:

SELECT  *
FROM    (
        VALUES
        (1, 2),
        (3, 4)
        ) AS q (col1, col2)

In other systems, just use UNION ALL:

SELECT  1 AS col1, 2 AS col2
-- FROM    dual
-- uncomment the line above if in Oracle
UNION ALL
SELECT  3 AS col1, 3 AS col2
-- FROM    dual
-- uncomment the line above if in Oracle

In Oracle, SQL Server and PostgreSQL, you also can generate recordsets of arbitrary number of rows (providable with an external variable):

SELECT  level
FROM    dual
CONNECT BY
        level <= :n

in Oracle,

WITH    q (l) AS
        (
        SELECT  1
        UNION ALL
        SELECT  l + 1
        FROM    q
        WHERE   l < @n
        )
SELECT  l
FROM    q
-- OPTION (MAXRECURSION 0)
-- uncomment line above if @n >= 100

in SQL Server,

SELECT  l
FROM    generate_series(1, $n) l

in PostgreSQL.

There are various replacement "malloc" libraries out there that will allow you to call a function at the end and it will tell you about all the unfreed memory, and in many cases, who malloced (or new'ed) it in the first place.

Matthew Watson can be modified to be used in RAC

inner join gv$session s on t.addr = s.taddr;

For completeness, here's kisp's solution ported to VB (can't add code to a comment)

Namespace Utils

''' <summary>
''' Subclass of WebClient to provide access to the timeout property

Public Class WebClient
    Inherits System.Net.WebClient

    Private _TimeoutMS As Integer = 0

    Public Sub New()
        MyBase.New()
    End Sub
    Public Sub New(ByVal TimeoutMS As Integer)
        MyBase.New()
        _TimeoutMS = TimeoutMS

Just use...

var stringContent = new StringContent(jObject.ToString());
var response = await httpClient.PostAsync("http://www.sample.com/write", stringContent);

Or,

var stringContent = new StringContent(JsonConvert.SerializeObject(model), Encoding.UTF8, "application/json");
var response = await httpClient.PostAsync("http://www.sample.com/write", stringContent);

I have always had good luck with using background images instead of trusting all browsers to interpret the bullet in exactly the same way. This would also give you tight control over the size of the bullet.

.moreLinks li {
    background: url("bullet.gif") no-repeat left 5px;
    padding-left: 1em;
}

Also, you may want to move your DIV outside of the UL. It's invalid markup as you have it now. You can use a list header LH if you must have it inside the list.

i = ['title', 'email', 'password2', 'password1', 'first_name', 
     'last_name', 'next', 'newsletter']
a, b = i.index('password2'), i.index('password1')
i[b], i[a] = i[a], i[b]

We Can use this method for changing the column index but should be applied to all the columns if there are more than two number of columns otherwise it will show all the Improper values from data table....................

Try:

With DependencedIncidents AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
),
lalala AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
)

And yes, you can reference common table expression inside common table expression definition. Even recursively. Which leads to some very neat tricks.

Here's an example

// in the service
getVehicles(){
    return Observable.interval(2200).map(i=> [{name: 'car 1'},{name: 'car 2'}])
}

// in the controller
vehicles: Observable<Array<any>>
ngOnInit() {
    this.vehicles = this._vehicleService.getVehicles();
}

// in template
<div *ngFor='let vehicle of vehicles | async'>
    {{vehicle.name}}
</div>

Have you tried the import text function.

wc -l <filename>

This will give you number of lines and filename in output.

Eg.

wc -l 24-11-2019-04-33-01-url_creator.log

Output

63 24-11-2019-04-33-01-url_creator.log

Use

wc -l <filename>|cut -d\ -f 1

to get only number of lines in output.

Eg.

wc -l 24-11-2019-04-33-01-url_creator.log|cut -d\ -f 1

Output

63

On SQL Server 2008 R2, I had a mismatch in table columns that caused the Rollback error. It went away when I fixed my sqlcmd table variable populated by the insert-exec statement to match that returned by the stored proc. It was missing org_code. In a windows cmd file, it loads result of stored procedure and selects it.

set SQLTXT= declare @resets as table (org_id nvarchar(9), org_code char(4), ^
tin(char9), old_strt_dt char(10), strt_dt char(10)); ^
insert @resets exec rsp_reset; ^
select * from @resets;

sqlcmd -U user -P pass -d database -S server -Q "%SQLTXT%" -o "OrgReport.txt"

no need to worry for a directory lock guys.

Just you need to do is, If sqllite3 is not installed, type below command,

>sudo apt-get install sqlite3

Open SVN database by typing this command,

>sqlite3 .svn/wc.db 

Now just you need to do is to remove locks entries from SVN DB.

sqlite>  select * from wc_lock;
1|-1           
sqlite>  delete from wc_lock;
sqlite>  select * from wc_lock;
sqlite>  .q

Process Completed. You can work on your SVN repository, do commit, update, add, remove operations without issue.

I made a library designed for input validations and one of the "modules" allows you to easily validate a bunch of stuff...

For example to validate an email:

let emailTrial = Trial.Email
let trial = emailTrial.trial()

if(trial(evidence: "[email protected]")) {
   //email is valid
}

SwiftCop is the library... hope it help!

    public:

    public slots:
        void MyTimerSlot();
    };

    #endif // MYTIME

mytimer.cpp:

#include "mytimer.h"

    timer = new QTimer(this);

    connect(timer, SIGNAL(timeout()),
          this, SLOT(MyTimerSlot()));

    // msec
    timer->start(1000);

    QCoreApplication a(argc, argv);

    // Create MyTimer instance
    // QTimer object will be created in the MyTimer constructor
    MyTimer timer;

    return a.exec();
}

If we run the code:

There are three major categories of cloud service models:

• Software as a service (SaaS)
• Platform as a service (PaaS)
• Infrastructure as a service (IaaS)

Software as a service (SaaS)

SaaS is a software that is centrally hosted and managed for the end customer. It's usually based on a multi-tenant architecture (a single version of the application is used for all customers) and typically is licensed through a monthly or annual subscription.

Example Office 365, Dropbox, Dynamics CRM Online are perfect examples of SaaS software, subscribers pay a monthly or annual subscription fee, and they get Exchange as a Service (online and/or desktop Outlook) or Storage as a Service (OneDrive and Dropbox).

Platform as a service (PaaS)

With PaaS, you deploy your application into an application-hosting environment (designed for building, testing, and deploying software applications) provided by the cloud service vendor. Developers have multiple ways to deploy their applications without knowing anything about what's happening in the background to supporting it.

Example Web Apps feature in Azure App Service and Azure Cloud Services (web and worker roles) are an example of PaaS.

Infrastructure as a service (IaaS)

An IaaS cloud vendor runs and manages server farms running virtualization software, enabling you to create VMs (running Windows or Linux) that run on the vendor’s infrastructure and install anything you want on it. Developers don’t have control over the hardware or virtualization software, but they have control over almost everything else. In fact, unlike PaaS, you are completely responsible for it.

Here are the current past AngularJS incantations:

angular.module('SharedServices', [])
    .config(function ($httpProvider) {
        $httpProvider.responseInterceptors.push('myHttpInterceptor');
        var spinnerFunction = function (data, headersGetter) {
            // todo start the spinner here
            //alert('start spinner');
            $('#mydiv').show();
            return data;
        };
        $httpProvider.defaults.transformRequest.push(spinnerFunction);
    })
// register the interceptor as a service, intercepts ALL angular ajax http calls
    .factory('myHttpInterceptor', function ($q, $window) {
        return function (promise) {
            return promise.then(function (response) {
                // do something on success
                // todo hide the spinner
                //alert('stop spinner');

Prerequisite:

Aria is used to improve the user experience of visually impaired users. Visually impaired users navigate though application using screen reader software like JAWS, NVDA,.. While navigating through the application, screen reader software announces content to users. Aria can be used to add content in the code which helps screen reader users understand role, state, label and purpose of the control

Aria does not change anything visually. (Aria is scared of designers too).

aria-label

aria-label attribute is used to communicate the label to screen reader users. Usually search input field does not have visual label (thanks to designers). aria-label can be used to communicate the label of control to screen reader users

How To Use:

<input type="edit" aria-label="search" placeholder="search">

There is no visual change in application. But screen readers can understand the purpose of control

aria-labelledby

Both aria-label and aria-labelledby is used to communicate the label. But aria-labelledby can be used to reference any label already present in the page whereas aria-label is used to communicate the label which i not displayed visually

Approach 1:

<span id="sd">Search</span>

<input type="text" aria-labelledby="sd">

Approach 2:

aria-labelledby can also be used to combine two labels for screen reader users

<span id="de">Billing Address</span>

<span id="sd">First Name</span>

<input type="text" aria-labelledby="de sd">

The file needs to be decompiled (or deodex'd not sure which one). But here's another way to do it:

-Download free Tickle My Android tool on XDA: https://forum.xda-developers.com/showthread.php?t=1633333https://forum.xda-developers.com/showthread.php?t=1633333
-Unzip
-Copy APK into \_WorkArea1\_in\ folder
-Open "Tickle My Android.exe"
-Theming Menu
-Decompile Files->Any key to continue (ignore warning)
-Decompile Files->1->[Enter]->y[Enter]
-Wait for it to decompile in new window... Done when new window closes
-Decompiled/viewable files will be here: \_WorkArea3\_working\[App]\

Please use below for particular column count

dataframe.columnName.isnull().sum()

A solution avoiding CASE WHEN is to use COALESCE.

SELECT
    t1.Col2 AS t1Col2,
    t2.Col2 AS t2Col2,
    COALESCE(NULLIF(t1.Col2, t2.Col2),NULLIF(t2.Col2, t1.Col2)) as NULL_IF_SAME
 FROM @t1 AS t1
JOIN @t2 AS t2 ON t1.ColID = t2.ColID

NULL_IF_SAME column will give NULL for all rows where t1.col2 = t2.col2 (including NULL). Though this is not more readable than CASE WHEN expression, it is ANSI SQL.

Just for the sake of fun, if one wants to have boolean bit values of 0 and 1 (though it is not very readable, hence not recommended), one can use (which works for all datatypes):

1/ISNULL(LEN(COALESCE(NULLIF(t1.Col2, t2.Col2),NULLIF(t2.Col2, t1.Col2)))+2,1) as BOOL_BIT_SAME.

Now if you have one of the numeric data types and want bits, in the above LEN function converts to string first which may be problematic,so instead this should work:

1/(CAST(ISNULL(ABS(COALESCE(NULLIF(t1.Col2, t2.Col2),NULLIF(t2.Col2, t1.Col2)))+1,0)as bit)+1) as FAST_BOOL_BIT_SAME_NUMERIC

Above will work for Integers without CAST.

NOTE: also in SQLServer 2012, we have IIF function.

I think you've got your understanding of the two properties off a little. Border affects the outside edge of the element, making the element different in size. Outline will not change the size or position of the element (takes up no space) and goes outside the border. From your description you want to use the border property.

Look at the simple example below in your browser:

<div style="height: 100px; width: 100px; background: black; color: white; outline: thick solid #00ff00">SOME TEXT HERE</div>_x000D_
_x000D_
<div style="height: 100px; width: 100px; background: black; color: white; border-left: thick solid #00ff00">SOME TEXT HERE</div>

Notice how the border pushes the bottom div over, but the outline doesn't move the top div and the outline actually overlaps the bottom div.

You can read more about it here:
Border
Outline

Cursor might used for retrieving data row by row basis.its act like a looping statement(ie while or for loop). To use cursors in SQL procedures, you need to do the following: 1.Declare a cursor that defines a result set. 2.Open the cursor to establish the result set. 3.Fetch the data into local variables as needed from the cursor, one row at a time. 4.Close the cursor when done.

for ex:

declare @tab table
(
Game varchar(15),
Rollno varchar(15)
)
insert into @tab values('Cricket','R11')
insert into @tab values('VollyBall','R12')

declare @game  varchar(20)
declare @Rollno varchar(20)

declare cur2 cursor for select game,rollno from @tab 

open cur2

fetch next from cur2 into @game,@rollno

WHILE   @@FETCH_STATUS = 0   
begin

print @game

print @rollno

FETCH NEXT FROM cur2 into @game,@rollno

end

close cur2

deallocate cur2

spin12.setLayoutParams(new LinearLayout.LayoutParams(200, 120));

spin12 is your spinner and 200,120 is width and height for your spinner.

Boolean wraps the boolean primitive type. In JDK 5 and upwards, Oracle (or Sun before Oracle bought them) introduced autoboxing/unboxing, which essentially allows you to do this

boolean result = Boolean.TRUE;

or

Boolean result = true; 

Which essentially the compiler does,

Boolean result = Boolean.valueOf(true);

So, for your answer, it's YES.

/* Most Accurate Setting if you only want

To select every nth element from any starting position in the vector

nth_element <- function(vector, starting_position, n) { 
  vector[seq(starting_position, length(vector), n)] 
  }

# E.g.
vec <- 1:12

nth_element(vec, 1, 3)
# [1]  1  4  7 10

nth_element(vec, 2, 3)
# [1]  2  5  8 11

Your code below is zooming the map to fit the specified bounds:

addMarker(27.703402,85.311668,'New Road');
center = bounds.getCenter();
map.fitBounds(bounds);

If you only have 1 marker and add it to the bounds, that results in the closest zoom possible:

function addMarker(lat, lng, info) {
  var pt = new google.maps.LatLng(lat, lng);
  bounds.extend(pt);
}

If you keep track of the number of markers you have "added" to the map (or extended the bounds with), you can only call fitBounds if that number is greater than one. I usually push the markers into an array (for later use) and test the length of that array.

If you will only ever have one marker, don't use fitBounds. Call setCenter, setZoom with the marker position and your desired zoom level.

function addMarker(lat, lng, info) {
  var pt = new google.maps.LatLng(lat, lng);
  map.setCenter(pt);
  map.setZoom(your desired zoom);
}

JWT vs Cookie Auth

|                    | Cookie        | JWT                             |
| Stateless          | No            | Yes                             |
| Cross domain usage | No            | Yes                             |
| Mobile ready       | No            | Yes                             |
| Performance        | Low           | High (no need in request to DB) |
| Add to request     | Automatically | Manually (if not in cookie)     |

I finally found a solution on Windows, to have a real silent and automatic install:

On Windows, the following syntax doesn't work:

echo y | sdkmanager --licenses

It seems the "y" aren't correctly sent to the java program called in the batch.

The workaround is to create a file file-y.txt with several "y", one by line, and to use

call sdkmanager --licenses < file-y.txt

This will create the needed files in the licenses directory. The problem is probably related to the use of BufferedReader in Java

data = pd.DataFrame({"a":[1,2,3,34],"b":[5,6,7,8]})
new_data = pd.melt(data)
new_data.set_index("variable", inplace=True)

This gives a dataframe with index as column name of data and all data are present in "values" column

You have to use (for checkboxes) :checkbox and the .name attribute to select by class.

For example:

$("input.aclass:checkbox")

The :checkbox selector:

Matches all input elements of type checkbox. Using this psuedo-selector like $(':checkbox') is equivalent to $('*:checkbox') which is a slow selector. It's recommended to do $('input:checkbox').

You should read jQuery documentation to know about selectors.

Here is the correct solution using list comprehensions (they're backward in the question):

>>> join = lambda it: (y for x in it for y in x)
>>> list(join([[1,2],[3,4,5],[]]))
[1, 2, 3, 4, 5]

In your case it would be

[image for menuitem in list_of_menuitems for image in menuitem.image_set.all()]

or you could use join and say

join(menuitem.image_set.all() for menuitem in list_of_menuitems)

In either case, the gotcha was the nesting of the for loops.

What comes after the "Where" is a constraint on the generic type T you declared, so:

• class means that the T should be a class and not a value type or a struct.

• new() indicates that the T class should have a public parameter-free default constructor defined.

I had a similar issue or maybe just related.

For my case I was accessing properties of an object but one was undefined. I found the problem was a white-space in the server side code while creating the key,val of the object.

My approach was as follows...

After removing the white-space from the server-side code creating the object, I could now access the property as below...

This might not be the issue with the case of the subject question but was for my case and may be so for some one else. Hope it helps.

Since maps v2 is deprecated, you are probably interested in v3 maps: https://developers.google.com/maps/documentation/javascript/markers#simple_icons

For v2 maps:

http://code.google.com/apis/maps/documentation/overlays.html#Icons_overview

You would have one set of logic do all the 'regular' pins, and another that does the 'special' pin(s) using the new marker defined.

Like this:

#include <fstream>
#include <string>

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

  std::ifstream ifs("myfile.txt");
  std::string content( (std::istreambuf_iterator<char>(ifs) ),
                       (std::istreambuf_iterator<char>()    ) );

  return 0;
}

The statement

  std::string content( (std::istreambuf_iterator<char>(ifs) ),
                       (std::istreambuf_iterator<char>()    ) );

can be split into

std::string content;
content.assign( (std::istreambuf_iterator<char>(ifs) ),
                (std::istreambuf_iterator<char>()    ) );

which is useful if you want to just overwrite the value of an existing std::string variable.

You can simply use this:

'07311954' in df.date.values which returns True or False

Here is the further explanation:

In pandas, using in check directly with DataFrame and Series (e.g. val in df or val in series ) will check whether the val is contained in the Index.

BUT you can still use in check for their values too (instead of Index)! Just using val in df.col_name.values or val in series.values. In this way, you are actually checking the val with a Numpy array.

And .isin(vals) is the other way around, it checks whether the DataFrame/Series values are in the vals. Here vals must be set or list-like. So this is not the natural way to go for the question.

if( myVariable ) 
{ 
    //mayVariable is not : 
    //null 
    //undefined 
    //NaN 
    //empty string ("") 
    //0 
    //false 
}

See if the plugin has a 'skip' configuration parameter. Nearly all do. if it does, just add it to a declaration in the child:

<plugin>
   <groupId>group</groupId>
   <artifactId>artifact</artifactId>
   <configuration>
     <skip>true</skip>
   </configuration>
</plugin>

If not, then use:

<plugin>    
<groupId>group</groupId>   
 <artifactId>artifact</artifactId>    
<executions>
     <execution>
       <id>TheNameOfTheRelevantExecution</id>
       <phase>none</phase>
     </execution>    
</executions>  
</plugin>

when you add a new data set to a geom you need to use the data= argument. Or put the arguments in the proper order mapping=..., data=.... Take a look at the arguments for ?geom_line.

Thus:

p + geom_line(data=df.last, aes(HrEnd, MWh, group=factor(Date)), color="red") 

Or:

p + geom_line(aes(HrEnd, MWh, group=factor(Date)), df.last, color="red") 

It is working you have to check attr after assigning value

$('#amount').attr( 'datamin','1000');

alert($('#amount').attr( 'datamin'));?

Perl one-liner:

perl -F'/[\/=]/' -lane 'print "$F[2]\t$F[4]\t$F[7]"' file

These command-line options are used:

• -n loop around every line of the input file, put the line in the $_ variable, do not automatically print every line

• -l removes newlines before processing, and adds them back in afterwards

• -a autosplit mode – perl will automatically split input lines into the @F array. Defaults to splitting on whitespace

• -F autosplit modifier, in this example splits on either / or =

• -e execute the perl code

Perl is closely related to awk, however, the @F autosplit array starts at index $F[0] while awk fields start with $1.

The __del__ method, it will be called when the object is garbage collected. Note that it isn't necessarily guaranteed to be called though. The following code by itself won't necessarily do it:

del obj

The reason being that del just decrements the reference count by one. If something else has a reference to the object, __del__ won't get called.

There are a few caveats to using __del__ though. Generally, they usually just aren't very useful. It sounds to me more like you want to use a close method or maybe a with statement.

See the python documentation on __del__ methods.

One other thing to note: __del__ methods can inhibit garbage collection if overused. In particular, a circular reference that has more than one object with a __del__ method won't get garbage collected. This is because the garbage collector doesn't know which one to call first. See the documentation on the gc module for more info.

The li tag has a property called list-style-position. This makes your bullets inside or outside the list. On default, it’s set to inside. That makes your text wrap around it. If you set it to outside, the text of your li tags will be aligned.

The downside of that is that your bullets won't be aligned with the text outside the ul. If you want to align it with the other text you can use a margin.

ul li {
    /*
     * We want the bullets outside of the list,
     * so the text is aligned. Now the actual bullet
     * is outside of the list’s container
     */
    list-style-position: outside;

    /*
     * Because the bullet is outside of the list’s
     * container, indent the list entirely
     */
    margin-left: 1em;
}

Edit 15th of March, 2014 Seeing people are still coming in from Google, I felt like the original answer could use some improvement

• Changed the code block to provide just the solution
• Changed the indentation unit to em’s
• Each property is applied to the ul element
• Good comments :)

Here's another way to accomplish the equivalent of Write-Output. Just put your string in quotes:

"count=$count"

You can make sure this works the same as Write-Output by running this experiment:

"blah blah" > out.txt

Write-Output "blah blah" > out.txt

Write-Host "blah blah" > out.txt

The first two will output "blah blah" to out.txt, but the third one won't.

"help Write-Output" gives a hint of this behavior:

This cmdlet is typically used in scripts to display strings and other objects on the console. However, because the default behavior is to display the objects at the end of a pipeline, it is generally not necessary to use the cmdlet.

In this case, the string itself "count=$count" is the object at the end of a pipeline, and is displayed.

What about SDL?

Perhaps it's a bit too complex for your needs, but it's certainly cross-platform.

You can use curl instead.

version=1.2.3
artifact="artifact"
repoId=repositoryId
groupId=org/myorg
REPO_URL=http://localhost:8081/nexus

curl -u username:password --upload-file filename.tgz $REPO_URL/content/repositories/$repoId/$groupId/$artefact/$version/$artifact-$version.tgz

For Evergreen browsers, this will build a staircase based on an incoming character and the number of stairs to build.
function StairCase(character, input) {
    let i = 0;
    while (i < input) {
        const spaces = " ".repeat(input - (i+1));
        const hashes = character.repeat(i + 1);
        console.log(spaces + hashes);
        i++;
    }
}

//Implement
//Refresh the console
console.clear();
StairCase("#",6);   

You can also add a polyfill for Repeat for older browsers

    if (!String.prototype.repeat) {
      String.prototype.repeat = function(count) {
        'use strict';
        if (this == null) {
          throw new TypeError('can\'t convert ' + this + ' to object');
        }
        var str = '' + this;
        count = +count;
        if (count != count) {
          count = 0;
        }
        if (count < 0) {
          throw new RangeError('repeat count must be non-negative');
        }
        if (count == Infinity) {
          throw new RangeError('repeat count must be less than infinity');
        }
        count = Math.floor(count);
        if (str.length == 0 || count == 0) {
          return '';
        }
        // Ensuring count is a 31-bit integer allows us to heavily optimize the
        // main part. But anyway, most current (August 2014) browsers can't handle
        // strings 1 << 28 chars or longer, so:
        if (str.length * count >= 1 << 28) {
          throw new RangeError('repeat count must not overflow maximum string size');
        }
        var rpt = '';
        for (;;) {
          if ((count & 1) == 1) {
            rpt += str;
          }
          count >>>= 1;
          if (count == 0) {
            break;
          }
          str += str;
        }
        // Could we try:
        // return Array(count + 1).join(this);
        return rpt;
      }
    }

I usually use the excellent Gucharmap to look up Unicode characters. It's installed on all recent Linux installations with Gnome under the name "Character Map". I don't know of any equivalent tools for Windows or Mac OS X, but its homepage lists a few.

If you are using Spring boot, you should add this plugin in your pom.xml:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

The following is my solution. Test it if it works for you:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-dependency-plugin</artifactId>
    <executions>
        <execution>
            <id>copy-dependencies</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>copy-dependencies</goal>
            </goals>
            <configuration>
                <outputDirectory>${project.build.directory}/classes/lib</outputDirectory>
                <overWriteReleases>false</overWriteReleases>
                <overWriteSnapshots>false</overWriteSnapshots>
                <overWriteIfNewer>true</overWriteIfNewer>
            </configuration>
        </execution>
    </executions>
</plugin>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <addClasspath>true</addClasspath>
                <!-- <classpathPrefix>lib</classpathPrefix> -->
                <!-- <mainClass>test.org.Cliente</mainClass> -->
            </manifest>
            <manifestEntries>
                <Class-Path>lib/</Class-Path>
            </manifestEntries>
        </archive>
    </configuration>
</plugin>

The first plugin puts all dependencies in the target/classes/lib folder, and the second one includes the library folder in the final JAR file, and configures the Manifest.mf file.

But then you will need to add custom classloading code to load the JAR files.

Or, to avoid custom classloading, you can use "${project.build.directory}/lib, but in this case, you don't have dependencies inside the final JAR file, which defeats the purpose.

It's been two years since the question was asked. The problem of nested JAR files persists nevertheless. I hope it helps somebody.

Use Guava's Stopwatch class.

An object that measures elapsed time in nanoseconds. It is useful to measure elapsed time using this class instead of direct calls to System.nanoTime() for a few reasons:

• An alternate time source can be substituted, for testing or performance reasons.
• As documented by nanoTime, the value returned has no absolute meaning, and can only be interpreted as relative to another timestamp returned by nanoTime at a different time. Stopwatch is a more effective abstraction because it exposes only these relative values, not the absolute ones.

Stopwatch stopwatch = Stopwatch.createStarted();
doSomething();
stopwatch.stop(); // optional

long millis = stopwatch.elapsed(TimeUnit.MILLISECONDS);

log.info("that took: " + stopwatch); // formatted string like "12.3 ms"

margin-top:0;
margin-bottom:0;
margin-left:auto;
margin-right:auto;

0 is for top-bottom and auto for left-right. The browser sets the margin.

There are 3 things you need.

1. You need to oAuth with the owner of those photos. (with the 'user_photos' extended permission)

2. You need the access token (which you get returned in the URL box after the oAuth is done.)

3. When those are complete you can then access the photos like so https://graph.facebook.com/me?access_token=ACCESS_TOKEN

You can find all of the information in more detail here: http://developers.facebook.com/docs/authentication

It seems the docs/tool have been updated and you can now add the image tag to your script. This was successful for me.

Example:

version: '2'
services:

  baggins.api.rest:
    image: my.image.name:rc2
    build:
      context: ../..
      dockerfile: app/Docker/Dockerfile.release
    ports:
      ...

Update November 2018

After working and blogging about MVC and MVP in Android for several years (see the body of the answer below), I decided to capture my knowledge and understanding in a more comprehensive and easily digestible form.

So, I released a full blown video course about Android applications architecture. So, if you're interested in mastering the most advanced architectural patterns in Android development, check out this comprehensive course here.

This answer was updated in order to remain relevant as of November 2016

It looks like you are seeking for architectural patterns rather than design patterns.

Design patterns aim at describing a general "trick" that programmer might implement for handling a particular set of recurring software tasks. For example: In OOP, when there is a need for an object to notify a set of other objects about some events, the observer design pattern can be employed.

Since Android applications (and most of AOSP) are written in Java, which is object-oriented, I think you'll have a hard time looking for a single OOP design pattern which is NOT used on Android.

Architectural patterns, on the other hand, do not address particular software tasks - they aim to provide templates for software organization based on the use cases of the software component in question.

It sounds a bit complicated, but I hope an example will clarify: If some application will be used to fetch data from a remote server and present it to the user in a structured manner, then MVC might be a good candidate for consideration. Note that I said nothing about software tasks and program flow of the application - I just described it from user's point of view, and a candidate for an architectural pattern emerged.

Since you mentioned MVC in your question, I'd guess that architectural patterns is what you're looking for.

Historically, there were no official guidelines by Google about applications' architectures, which (among other reasons) led to a total mess in the source code of Android apps. In fact, even today most applications that I see still do not follow OOP best practices and do not show a clear logical organization of code.

But today the situation is different - Google recently released the Data Binding library, which is fully integrated with Android Studio, and, even, rolled out a set of architecture blueprints for Android applications.

Two years ago it was very hard to find information about MVC or MVP on Android. Today, MVC, MVP and MVVM has become "buzz-words" in the Android community, and we are surrounded by countless experts which constantly try to convince us that MVx is better than MVy. In my opinion, discussing whether MVx is better than MVy is totally pointless because the terms themselves are very ambiguous - just look at the answers to this question, and you'll realize that different people can associate these abbreviations with completely different constructs.

Due to the fact that a search for a best architectural pattern for Android has officially been started, I think we are about to see several more ideas come to light. At this point, it is really impossible to predict which pattern (or patterns) will become industry standards in the future - we will need to wait and see (I guess it is matter of a year or two).

However, there is one prediction I can make with a high degree of confidence: Usage of the Data Binding library will not become an industry standard. I'm confident to say that because the Data Binding library (in its current implementation) provides short-term productivity gains and some kind of architectural guideline, but it will make the code non-maintainable in the long run. Once long-term effects of this library will surface - it will be abandoned.

Now, although we do have some sort of official guidelines and tools today, I, personally, don't think that these guidelines and tools are the best options available (and they are definitely not the only ones). In my applications I use my own implementation of an MVC architecture. It is simple, clean, readable and testable, and does not require any additional libraries.

This MVC is not just cosmetically different from others - it is based on a theory that Activities in Android are not UI Elements, which has tremendous implications on code organization.

So, if you're looking for a good architectural pattern for Android applications that follows SOLID principles, you can find a description of one in my post about MVC and MVP architectural patterns in Android.

This is a 100% solution. I tried it myself.

myisamchk -r -v -f --sort_buffer_size=128M --key_buffer_size=128M /var/lib/mysql/databasename/tabloname

Simple:

btn.setBackground(Color.red);

To use RGB values:

btn[i].setBackground(Color.RGBtoHSB(int, int, int, float[]));

To Convert BEGIN OPENSSH PRIVATE KEY to BEGIN RSA PRIVATE KEY:

ssh-keygen -p -m PEM -f ~/.ssh/id_rsa

cat file.txt | grep "company_name" | cut -d '=' -f 2 | cut -d ';' -f 1

Disclaimer: This approach is a naive illustration of Ruby's capabilities, and not a production-grade solution for replacing strings in files. It's prone to various failure scenarios, such as data loss in case of a crash, interrupt, or disk being full. This code is not fit for anything beyond a quick one-off script where all the data is backed up. For that reason, do NOT copy this code into your programs.

Here's a quick short way to do it.

file_names = ['foo.txt', 'bar.txt']

file_names.each do |file_name|
  text = File.read(file_name)
  new_contents = text.gsub(/search_regexp/, "replacement string")

  # To merely print the contents of the file, use:
  puts new_contents

  # To write changes to the file, use:
  File.open(file_name, "w") {|file| file.puts new_contents }
end

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

I experienced this issue today and started searching on internet. In my case there was no table in my DB. I forgot to import the tables on the online server. I did it and all works fine.
