You can indeed not define the filter execution order using @WebFilter annotation. However, to minimize the web.xml usage, it's sufficient to annotate all filters with just a filterName so that you don't need the <filter> definition, but just a <filter-mapping> definition in the desired order.

For example,

@WebFilter(filterName="filter1")
public class Filter1 implements Filter {}

@WebFilter(filterName="filter2")
public class Filter2 implements Filter {}

with in web.xml just this:

<filter-mapping>
    <filter-name>filter1</filter-name>
    <url-pattern>/url1/*</url-pattern>
</filter-mapping>
<filter-mapping>
    <filter-name>filter2</filter-name>
    <url-pattern>/url2/*</url-pattern>
</filter-mapping>

If you'd like to keep the URL pattern in @WebFilter, then you can just do like so,

@WebFilter(filterName="filter1", urlPatterns="/url1/*")
public class Filter1 implements Filter {}

@WebFilter(filterName="filter2", urlPatterns="/url2/*")
public class Filter2 implements Filter {}

but you should still keep the <url-pattern> in web.xml, because it's required as per XSD, although it can be empty:

<filter-mapping>
    <filter-name>filter1</filter-name>
    <url-pattern />
</filter-mapping>
<filter-mapping>
    <filter-name>filter2</filter-name>
    <url-pattern />
</filter-mapping>

Regardless of the approach, this all will fail in Tomcat until version 7.0.28 because it chokes on presence of <filter-mapping> without <filter>. See also Using Tomcat, @WebFilter doesn't work with <filter-mapping> inside web.xml

From sed1line:

# print line number 52
sed -n '52p'                 # method 1
sed '52!d'                   # method 2
sed '52q;d'                  # method 3, efficient on large files

From awk1line:

# print line number 52
awk 'NR==52'
awk 'NR==52 {print;exit}'          # more efficient on large files

You get this error because a class which has no constructor has a default constructor, which is argument-less and is equivalent to the following code:

public ACSubClass() {
    super();
}

However since your BaseClass declares a constructor (and therefore doesn't have the default, no-arg constructor that the compiler would otherwise provide) this is illegal - a class that extends BaseClass can't call super(); because there is not a no-argument constructor in BaseClass.

This is probably a little counter-intuitive because you might think that a subclass automatically has any constructor that the base class has.

The simplest way around this is for the base class to not declare a constructor (and thus have the default, no-arg constructor) or have a declared no-arg constructor (either by itself or alongside any other constructors). But often this approach can't be applied - because you need whatever arguments are being passed into the constructor to construct a legit instance of the class.

try like this

= IIF( MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ) ) = -1, "",  FormatNumber(  MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ), "CellReading_Reading"),3)) )

I dont know what do you exactly mean but hope it help you.
by this directive you can access the DOM element inside controller
this is sample that help you to focus element inside controller

.directive('scopeElement', function () {
    return {
        restrict:"A", // E-Element A-Attribute C-Class M-Comments
        replace: false,
        link: function($scope, elem, attrs) {
            $scope[attrs.scopeElement] = elem[0];
        }
    };
})

now, inside HTML

<input scope-element="txtMessage" >

then, inside controller :

.controller('messageController', ['$scope', function ($scope) {
    $scope.txtMessage.focus();
}])

By the RFC7231 it does not matter and may be empty

How we implement json api standard based solution in the project:

post/put: outputs object attributes as in get (field filter/relations applies the same)

delete: data only contains null (for its a representation of missing object)

status for standard delete: 200

must means: The clause (query) must appear in matching documents. These clauses must match, like logical AND.

should means: At least one of these clauses must match, like logical OR.

Basically they are used like logical operators AND and OR. See this.

Now in a bool query:

must means: Clauses that must match for the document to be included.

should means: If these clauses match, they increase the _score; otherwise, they have no effect. They are simply used to refine the relevance score for each document.

Yes you can use multiple filters inside must.

I hope this helps others with this error.

Run the httpd.exe from the command line to get an accurate description of the problem.

I had the same error message and it turned out to be a miss configured ServerRoot path. Even after running setup_xampp.bat the httpd.conf had the wrong path.

My error.log was empty and starting the service does not give an informative error message.

A small update to this. raw_input() is renamed as input() in Python 3.

I've used a few CSS hacks and targeted Chrome/Safari/Firefox/IE individually, as each browser renders selects a bit differently. I've tested on all browsers except IE.

For Safari/Chrome, set the height and line-height you want for your <select />.

For Firefox, we're going to kill Firefox's default padding and border, then set our own. Set padding to whatever you like.

For IE 8+, just like Chrome, we've set the height and line-height properties. These two media queries can be combined. But I kept it separate for demo purposes. So you can see what I'm doing.

Please note, for the height/line-height property to work in Chrome/Safari OSX, you must set the background to a custom value. I changed the color in my example.

Here's a jsFiddle of the below: http://jsfiddle.net/URgCB/4/

For the non-hack route, why not use a custom select plug-in via jQuery? Check out this: http://codepen.io/wallaceerick/pen/ctsCz

HTML:

<select>
    <option>Here's one option</option>
    <option>here's another option</option>
</select>

CSS:

@media screen and (-webkit-min-device-pixel-ratio:0) {  /*safari and chrome*/
    select {
        height:30px;
        line-height:30px;
        background:#f4f4f4;
    } 
}
select::-moz-focus-inner { /*Remove button padding in FF*/ 
    border: 0;
    padding: 0;
}
@-moz-document url-prefix() { /* targets Firefox only */
    select {
        padding: 15px 0!important;
    }
}        
@media screen\0 { /* IE Hacks: targets IE 8, 9 and 10 */        
    select {
        height:30px;
        line-height:30px;
    }     
}

Other answers are correct, especially the one by Jon Skeet, but outdated.

java.time

These old date-time classes have been supplanted by the java.time framework built into Java 8 and later.

If you simply want the current time in UTC, use the Instant class.

Instant now = Instant.now();

EST is not a time zone, as explained in the correct Answer by Jon Skeet. Such 3-4 letter codes are neither standardized nor unique, and further the confusion over Daylight Saving Time (DST). Use a proper time zone name in the "continent/region" format.

Perhaps you meant Eastern Standard Time in east coast of north America? Or Egypt Standard Time? Or European Standard Time?

ZoneId zoneId = ZoneId.of( "America/New_York" );
ZoneId zoneId = ZoneId.of( "Africa/Cairo" );
ZoneId zoneId = ZoneId.of( "Europe/Lisbon" );

Use any such ZoneId object to get the current moment adjusted to a particular time zone to produce a ZonedDateTime object.

ZonedDateTime zdt = ZonedDateTime.now( zoneId ) ;

Adjust that ZonedDateTime into a different time zone by producing another ZonedDateTime object from the first. The java.time framework uses immutable objects rather than changing (mutating) existing objects.

ZonedDateTime zdtGuam = zdt.withZoneSameInstant( ZoneId.of( "Pacific/Guam" ) ) ;

By adding using System.Timers; to your program you can use this function:

private static void delay(int Time_delay)
{
   int i=0;
  //  ameTir = new System.Timers.Timer();
    _delayTimer = new System.Timers.Timer();
    _delayTimer.Interval = Time_delay;
    _delayTimer.AutoReset = false; //so that it only calls the method once
    _delayTimer.Elapsed += (s, args) => i = 1;
    _delayTimer.Start();
    while (i == 0) { };
}

Delay is a function and can be used like:

delay(5000);

I'll throw mine in the mix:

https://gist.github.com/btm1/6802312

this evaluates the if statement once and adds no watch listener BUT you can add an additional attribute to the element that has the set-if called wait-for="somedata.prop" and it will wait for that data or property to be set before evaluating the if statement once. that additional attribute can be very handy if you're waiting for data from an XHR request.

angular.module('setIf',[]).directive('setIf',function () {
    return {
      transclude: 'element',
      priority: 1000,
      terminal: true,
      restrict: 'A',
      compile: function (element, attr, linker) {
        return function (scope, iterStartElement, attr) {
          if(attr.waitFor) {
            var wait = scope.$watch(attr.waitFor,function(nv,ov){
              if(nv) {
                build();
                wait();
              }
            });
          } else {
            build();
          }

          function build() {
            iterStartElement[0].doNotMove = true;
            var expression = attr.setIf;
            var value = scope.$eval(expression);
            if (value) {
              linker(scope, function (clone) {
                iterStartElement.after(clone);
                clone.removeAttr('set-if');
                clone.removeAttr('wait-for');
              });
            }
          }
        };
      }
    };
  });

If you want to create model along with migration use this command:-

sequelize model:create --name regions --attributes name:string,status:boolean --underscored

--underscored it is used to create column having underscore like:- created_at,updated_at or any other column having underscore and support user defined columns having underscore.

For regular Windows users who are not skilled with computers, it is practically not possible to install and use extensions from outside the Chrome Web Store.

Users of other operating systems (Linux, Mac, Chrome OS) can easily install unpacked extensions (in developer mode).
Windows users can also load an unpacked extension, but they will always see an information bubble with "Disable developer mode extensions" when they start Chrome or open a new incognito window, which is really annoying. The only way for Windows users to use unpacked extensions without such dialogs is to switch to Chrome on the developer channel, by installing https://www.google.com/chrome/browser/index.html?extra=devchannel#eula.

Extensions can be loaded in unpacked mode by following the following steps:

1. Visit chrome://extensions (via omnibox or menu -> Tools -> Extensions).
2. Enable Developer mode by ticking the checkbox in the upper-right corner.
3. Click on the "Load unpacked extension..." button.
4. Select the directory containing your unpacked extension.

If you have a crx file, then it needs to be extracted first. CRX files are zip files with a different header. Any capable zip program should be able to open it. If you don't have such a program, I recommend 7-zip.

These steps will work for almost every extension, except extensions that rely on their extension ID. If you use the previous method, you will get an extension with a random extension ID. If it is important to preserve the extension ID, then you need to know the public key of your CRX file and insert this in your manifest.json. I have previously given a detailed explanation on how to get and use this key at https://stackoverflow.com/a/21500707.

One approach (which I can't imagine is good programming practice) is to add the ... which is traditionally used to pass arguments specified in one function to another.

> multiply <- function(a,b) a*b
> multiply(a = 2,b = 4,c = 8)
Error in multiply(a = 2, b = 4, c = 8) : unused argument(s) (c = 8)
> multiply2 <- function(a,b,...) a*b
> multiply2(a = 2,b = 4,c = 8)
[1] 8

You can read more about ... is intended to be used here

Use XMLHttpRequest

var xhr = new XMLHttpRequest();
xhr.open("POST", '/server', true);

//Send the proper header information along with the request
xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");

xhr.onreadystatechange = function() { // Call a function when the state changes.
    if (this.readyState === XMLHttpRequest.DONE && this.status === 200) {
        // Request finished. Do processing here.
    }
}
xhr.send("foo=bar&lorem=ipsum");
// xhr.send(new Int8Array()); 
// xhr.send(document);

One possible approach, if you just need to specify a parameter once and replicate it in several places, is to do something like this:

SELECT
  str_size  /* my variable usage */
  , LPAD(TRUNC(DBMS_RANDOM.VALUE * POWER(10, str_size)), str_size, '0') rand
FROM
  dual  /* or any other table, or mixed of joined tables */
  CROSS JOIN (SELECT 8 str_size FROM dual);  /* my variable declaration */

This code generates a string of 8 random digits.

Notice that I create a kind of alias named str_size that holds the constant 8. It is cross-joined to be used more than once in the query.

To just run a command as admin in a non-elevated Powershell, you can use Start-Process directly, with the right options, particularly -Verb runas.

It's a lot more convoluted than sudo, particularly because you can't just re-use the previous command with an additional option. You need to specify the arguments to your command separately.

Here is an example, using the route command to change the gateway :

This fails because we are not in an elevated PS:

> route change 0.0.0.0 mask 0.0.0.0 192.168.1.3
The requested operation requires elevation.

This works after accepting the UAC:

> Start-Process route -ArgumentList "change 0.0.0.0 mask 0.0.0.0 192.168.1.3" -Verb runas

Or for a command that requires cmd.exe:

> Start-Process cmd -ArgumentList "/c other_command arguments ..." -Verb runas

This is a much better and secured way. Working like a charm!

   private void startFloatingWidgetService() {
        startService(new Intent(MainActivity.this,FloatingWidgetService.class)
                .setAction(FloatingWidgetService.ACTION_PLAY));
    }

instead of :

 private void startFloatingWidgetService() {
        startService(new Intent(FloatingWidgetService.ACTION_PLAY));
    }

Because when you try 2nd one then you get an error saying : java.lang.IllegalArgumentException: Service Intent must be explicit: Intent { act=com.floatingwidgetchathead_demo.SampleService.ACTION_START }

Then your Service be like this :

static final String ACTION_START = "com.floatingwidgetchathead_demo.SampleService.ACTION_START";
    static final String ACTION_PLAY = "com.floatingwidgetchathead_demo.SampleService.ACTION_PLAY";
    static final String ACTION_PAUSE = "com.floatingwidgetchathead_demo.SampleService.ACTION_PAUSE";
    static final String ACTION_DESTROY = "com.yourcompany.yourapp.SampleService.ACTION_DESTROY";

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

Is this what you are trying to do?

# Our data
text <- c("F.US.CLE.V13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13",

)

#  Split into individual elements by the '.' character
#  Remember to escape it, because '.' by itself matches any single character
elems <- unlist( strsplit( text , "\\." ) )

#  We know the dataframe should have 4 columns, so make a matrix
m <- matrix( elems , ncol = 4 , byrow = TRUE )

#  Coerce to data.frame - head() is just to illustrate the top portion

Regex for integer and floating point numbers:

^[+-]?\d*\.\d+$|^[+-]?\d+(\.\d*)?$

A number can start with a period (without leading digits(s)), and a number can end with a period (without trailing digits(s)). Above regex will recognize both as correct numbers.

A . (period) itself without any digits is not a correct number. That's why we need two regex parts there (separated with a "|").

Hope this helps.

Not sure how it stacks up performance-wise, but for places where it doesn't really matter, I like this format because I can be sure it is using \r\n (CRLF) and not whatever format my PHP file happens to be saved in.

$text="line1\r\n" .
      "line2\r\n" .
      "line3\r\n";

It also lets me indent however I want.

You can always use iptables to delete the rules. If you have a lot of rules, just output them using the following command.

iptables-save > myfile

vi to edit them from the commend line. Just use the "dd" to delete the lines you no longer want.

I am using a facet_wrap in my ggplot and none of the suggested solutions worked for me except ArnaudA's solution:

You have to include the schema if isnt a public one

SELECT *
FROM <schema>."my_table"

Or you can change your default schema

SHOW search_path;
SET search_path TO my_schema;

Check your table schema here

SELECT *
FROM information_schema.columns

For example if a table is on the default schema public both this will works ok

SELECT * FROM parroquias_region
SELECT * FROM public.parroquias_region

But sectors need specify the schema

SELECT * FROM map_update.sectores_point

I encount this while I was calculating np.var(np.array([])). np.var will divide size of the array which is zero in this case.

Integer refers to the reference, that is, when comparing references you're comparing if they point to the same object, not value. Hence, the issue you're seeing. The reason it works so well with plain int types is that it unboxes the value contained by the Integer.

May I add that if you're doing what you're doing, why have the if statement to begin with?

mismatch = ( cdiCt != null && cdsCt != null && !cdiCt.equals( cdsCt ) );

Jwt is a strict set of instructions for the issuing and validating of signed access tokens. The tokens contain claims that are used by an app to limit access to a user

OAuth2 on the other hand is not a protocol, its a delegated authorization framework. think very detailed guideline, for letting users and applications authorize specific permissions to other applications in both private and public settings. OpenID Connect which sits on top of OAUTH2 gives you Authentication and Authorization.it details how multiple different roles, users in your system, server side apps like an API, and clients such as websites or native mobile apps, can authenticate with each othe

Note oauth2 can work with jwt , flexible implementation, extandable to different applications

Please use dataset

var article = document.querySelector('#electriccars'),
    data = article.dataset;

// data.columns -> "3"
// data.indexnumber -> "12314"
// data.parent -> "cars"

so in your case for setting data:

getElementById('item1').dataset.icon = "base2.gif";

using timedeltas you can do:

import datetime
today=datetime.date.today()


time=datetime.time()
print("today :",today)

# One day different .
five_day=datetime.timedelta(days=5)
print("one day :",five_day)
#output - 1 day , 00:00:00


# five day extend .
fitfthday=today+five_day
print("fitfthday",fitfthday)


# five day extend .
fitfthday=today+five_day
print("fitfthday",fitfthday)
#output - 
today : 2019-05-29
one day : 5 days, 0:00:00

I have a suspicion that this is related to the parser that BS will use to read the HTML. They document is here, but if you're like me (on OSX) you might be stuck with something that requires a bit of work:

You'll notice that in the BS4 documentation page above, they point out that by default BS4 will use the Python built-in HTML parser. Assuming you are in OSX, the Apple-bundled version of Python is 2.7.2 which is not lenient for character formatting. I hit this same problem, so I upgraded my version of Python to work around it. Doing this in a virtualenv will minimize disruption to other projects.

If doing that sounds like a pain, you can switch over to the LXML parser:

pip install lxml

And then try:

soup = BeautifulSoup(html, "lxml")

Depending on your scenario, that might be good enough. I found this annoying enough to warrant upgrading my version of Python. Using virtualenv, you can migrate your packages fairly easily.

You can use template module to copy if script exists on local machine to remote machine and execute it.

 - name: Copy script from local to remote machine
   hosts: remote_machine
   tasks:
    - name: Copy  script to remote_machine
      template: src=script.sh.2 dest=<remote_machine path>/script.sh mode=755
    - name: Execute script on remote_machine
      script: sh <remote_machine path>/script.sh

This is because, by default, Jaxb when serializes a pojo, looks for the annotations over the public members(getters or setters) of the properties. But, you are providing annotations on fields. so, either change and set the annotations on setters or getters of properties, or sets the XmlAccessortype to field.

Option 1::

@XmlRootElement(name = "fields")
@XmlAccessorType(XmlAccessType.FIELD)
public class Fields {

        @XmlElement(name = "field")
        List<Field> fields = new ArrayList<Field>();
        //getter, setter
}

@XmlAccessorType(XmlAccessType.FIELD)
public class Field {

       @XmlAttribute(name = "mappedField")
       String mappedField;
       //getter,setter
}

Option 2::

@XmlRootElement(name = "fields")
public class Fields {

        List<Field> fields = new ArrayList<Field>();

        @XmlElement(name = "field")
        public List<Field> getFields() {

        }

        //setter
}

@XmlAccessorType(XmlAccessType.FIELD)
public class Field {

       String mappedField;

       @XmlAttribute(name = "mappedField")
       public String getMappedField() {

       }

        //setter
}

For more detail and depth, check the following JDK documentation http://docs.oracle.com/javase/6/docs/api/javax/xml/bind/annotation/XmlAccessorType.html

. I usually do it element.value="<script>alert('test');</script>".

If sounds like you are generating an inline <script> element, in which case the </script> will end the HTML element and cause the script to terminate in the middle of the string.

Escape the / so that it isn't treated as an end tag by the HTML parser:

element.value = "<script>alert('test');<\/script>"

double minutes = varTime.TotalMinutes;
int minutesRounded = (int)Math.Round(varTime.TotalMinutes);

This won't work if the data is not sequential (1 2 3 4 but 5 7 3 1 5) as in that case you can't sort it.

Here is how I solve that issue for me:

Column A initial data that needs to contain 5 rows between each number - 5 4 6 8 9

Column B - 1 2 3 4 5 (final number represents the number of empty rows that you need to be between numbers in column A) copy-paste 1-5 in column B as long as you have numbers in column A.

Jump to D column, in D1 type 1. In D2 type this formula - =IF(B2=1,1+D1,D1) Drag it to the same length as column B.

Back to Column C - at C1 cell type this formula - =IF(B1=1,INDIRECT("a"&(D1)),""). Drag it down and we done. Now in column C we have same sequence of numbers as in column A distributed separately by 4 rows.

Updated answer for ES6+ is here.

arr = [1, 2, 3]; 

arr.forEach(function(i, idx, array){
   if (idx === array.length - 1){ 
       console.log("Last callback call at index " + idx + " with value " + i ); 
   }
});

would output:

Last callback call at index 2 with value 3

The way this works is testing arr.length against the current index of the array, passed to the callback function.

I setup my git to autorebase on a git checkout

# in my ~/.gitconfig file
[branch]
    autosetupmerge = always
    autosetuprebase = always

Otherwise, it automatically merges when you switch between branches, which I think is the worst possible choice as the default.

However, this has a side effect, when I switch to a branch and then git cherry-pick <commit-id> I end up in this weird state every single time it has a conflict.

I actually have to abort the rebase, but first I fix the conflict, git add /path/to/file the file (another very strange way to resolve the conflict in this case?!), then do a git commit -i /path/to/file. Now I can abort the rebase:

git checkout <other-branch>
git cherry-pick <commit-id>
...edit-conflict(s)...
git add path/to/file
git commit -i path/to/file
git rebase --abort
git commit .
git push --force origin <other-branch>

The second git commit . seems to come from the abort. I'll fix my answer if I find out that I should abort the rebase sooner.

The --force on the push is required if you skip other commits and both branches are not smooth (both are missing commits from the other).

You need to change from queue import Queue to from multiprocessing import Queue.

The root reason is the former Queue is designed for threading module Queue while the latter is for multiprocessing.Process module.

For details, you can read some source code or contact me!

Automatic copying to the clipboard may be dangerous, and therefore most browsers (except Internet Explorer) make it very difficult. Personally, I use the following simple trick:

function copyToClipboard(text) {
  window.prompt("Copy to clipboard: Ctrl+C, Enter", text);
}

The user is presented with the prompt box, where the text to be copied is already selected. Now it's enough to press Ctrl + C and Enter (to close the box) -- and voila!

Now the clipboard copy operation is safe, because the user does it manually (but in a pretty straightforward way). Of course, it works in all browsers.

<button id="demo" onclick="copyToClipboard(document.getElementById('demo').innerHTML)">This is what I want to copy</button>

<script>
  function copyToClipboard(text) {
    window.prompt("Copy to clipboard: Ctrl+C, Enter", text);
  }
</script>

I found the following code easy and working. Original answer is here https://www.postgresql.org/message-id/[email protected]

prova=> create table test(t text, i integer);
CREATE

prova=> insert into test values('123',123);
INSERT 64579 1

prova=> select cast(i as text),cast(t as int)from test;
text|int4
----+----
123| 123
(1 row)

hope it helps

And multiple concatenation:

from django import template
register = template.Library()


@register.simple_tag
def concat_all(*args):
    """concatenate all args"""
    return ''.join(map(str, args))

And in Template:

{% concat_all 'x' 'y' another_var as string_result %}
concatenated string: {{ string_result }}

You cannot achieve the desired solution with CSS z-index either, as z-index is only relative to the parent element. So if you have parents A and B with respective children a and b, b's z-index is only relative to other children of B and a's z-index is only relative to other children of A.

The z-index of A and B are relative to each other if they share the same parent element, but all of the children of one will share the same relative z-index at this level.

Websites - No solution file will be created. If we want to create websites no need for visual studio.

Web Application - A solution file will be created. If we want to create web application should need the visual studio. It will create a single .dll file in bin folder.

Researching this topic myself and having read the answers I recommend using the path.py library since it provides a context manager for changing the current working directory.

You then have something like

import path
if path.Path('../lib').isdir():
    with path.Path('..'):
        import lib

Although, you might just omit the isdir statement.

Here I'll add print statements to make it easy to follow what's happening

import path
import pandas

print(path.Path.getcwd())
print(path.Path('../lib').isdir())
if path.Path('../lib').isdir():
    with path.Path('..'):
        print(path.Path.getcwd())
        import lib
        print('Success!')
print(path.Path.getcwd())

which outputs in this example (where lib is at /home/jovyan/shared/notebooks/by-team/data-vis/demos/lib):

/home/jovyan/shared/notebooks/by-team/data-vis/demos/custom-chart
/home/jovyan/shared/notebooks/by-team/data-vis/demos
/home/jovyan/shared/notebooks/by-team/data-vis/demos/custom-chart

Since the solution uses a context manager, you are guaranteed to go back to your previous working directory, no matter what state your kernel was in before the cell and no matter what exceptions are thrown by importing your library code.

You can make it like this:

    MediaType JSON = MediaType.parse("application/json; charset=utf-8");
    RequestBody body = RequestBody.create(JSON, "{"jsonExample":"value"}");

    OkHttpClient client = new OkHttpClient();

    Request request = new Request.Builder()
            .url(url)
            .post(body)
            .addHeader("Authorization", "header value") //Notice this request has header if you don't need to send a header just erase this part
            .build();

    Call call = client.newCall(request);

    call.enqueue(new Callback() {
        @Override
        public void onFailure(Request request, IOException e) {

            Log.e("HttpService", "onFailure() Request was: " + request);

            e.printStackTrace();
        }

        @Override
        public void onResponse(Response r) throws IOException {

            response = r.body().string();

            Log.e("response ", "onResponse(): " + response );

        }
    });

Just going to add a simple example to what everyone has explained,

json.load()

json.load can deserialize a file itself i.e. it accepts a file object, for example,

# open a json file for reading and print content using json.load
with open("/xyz/json_data.json", "r") as content:
  print(json.load(content))

will output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I use json.loads to open a file instead,

# you cannot use json.loads on file object
with open("json_data.json", "r") as content:
  print(json.loads(content))

I would get this error:

TypeError: expected string or buffer

json.loads()

json.loads() deserialize string.

So in order to use json.loads I will have to pass the content of the file using read() function, for example,

using content.read() with json.loads() return content of the file,

with open("json_data.json", "r") as content:
  print(json.loads(content.read()))

Output,

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

That's because type of content.read() is string, i.e. <type 'str'>

If I use json.load() with content.read(), I will get error,

with open("json_data.json", "r") as content:
  print(json.load(content.read()))

Gives,

AttributeError: 'str' object has no attribute 'read'

So, now you know json.load deserialze file and json.loads deserialize a string.

Another example,

sys.stdin return file object, so if i do print(json.load(sys.stdin)), I will get actual json data,

cat json_data.json | ./test.py

{u'event': {u'id': u'5206c7e2-da67-42da-9341-6ea403c632c7', u'name': u'Sufiyan Ghori'}}

If I want to use json.loads(), I would do print(json.loads(sys.stdin.read())) instead.

If you're using a Unix like OS (Linux, OSX, etc) then you can use a combination of find and egrep to search for require statements containing your package name:

find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni 'name-of-package' {} \;

If you search for the entire require('name-of-package') statement, remember to use the correct type of quotation marks:

find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni 'require("name-of-package")' {} \;

or

find . -path ./node_modules -prune -o -name "*.js" -exec egrep -ni "require('name-of-package')" {} \;

The downside is that it's not fully automatic, i.e. it doesn't extract package names from package.json and check them. You need to do this for each package yourself. Since package.json is just JSON this could be remedied by writing a small script that uses child_process.exec to run this command for each dependency. And make it a module. And add it to the NPM repo...

The tabularx package gives you

1. the total width as a first parameter, and
2. a new column type X, all X columns will grow to fill up the total width.

For your example:

\usepackage{tabularx}
% ...    
\begin{document}
% ...

\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
Input & Output& Action return \\
\hline
\hline
DNF &  simulation & jsp\\
\hline
\end{tabularx}

If it's working from Postman, try new Spring version, becouse the 'org.springframework.boot' 2.2.2.RELEASE version can throw "Required request body content is missing" exception.
Try 2.2.6.RELEASE version.

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

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

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

I think most of these solutions are far too complicated. I assume that in your test controller you have this

 @Autowired
 private ObjectMapper objectMapper;

If its a rest service

@Test
public void test() throws Exception {
   mockMvc.perform(post("/person"))
          .contentType(MediaType.APPLICATION_JSON)
          .content(objectMapper.writeValueAsString(new Person()))
          ...etc
}

For spring mvc using a posted form I came up with this solution. (Not really sure if its a good idea yet)

private MultiValueMap<String, String> toFormParams(Object o, Set<String> excludeFields) throws Exception {
    ObjectReader reader = objectMapper.readerFor(Map.class);
    Map<String, String> map = reader.readValue(objectMapper.writeValueAsString(o));

    MultiValueMap<String, String> multiValueMap = new LinkedMultiValueMap<>();
    map.entrySet().stream()
            .filter(e -> !excludeFields.contains(e.getKey()))
            .forEach(e -> multiValueMap.add(e.getKey(), (e.getValue() == null ? "" : e.getValue())));
    return multiValueMap;
}



@Test
public void test() throws Exception {
  MultiValueMap<String, String> formParams = toFormParams(new Phone(), 
  Set.of("id", "created"));

   mockMvc.perform(post("/person"))
          .contentType(MediaType.APPLICATION_FORM_URLENCODED)
          .params(formParams))
          ...etc
}

The basic idea is to - first convert object to json string to get all the field names easily - convert this json string into a map and dump it into a MultiValueMap that spring expects. Optionally filter out any fields you dont want to include (Or you could just annotate fields with @JsonIgnore to avoid this extra step)

public class ThreadParameter
        {
            public int Port { get; set; }
            public string Path { get; set; }
        }


Thread t = new Thread(new ParameterizedThreadStart(Startup));
t.Start(new ThreadParameter() { Port = port, Path = path});

Create an object with the port and path objects and pass it to the Startup method.

As others have answered, you probably have a DATETIME (or other variation) column and not a DATE datatype.

Here's a condition that works for all, including DATE:

SELECT * 
FROM xxx 
WHERE dates >= '20121026' 
  AND dates <  '20121028'    --- one day after 
                             --- it is converted to '2012-10-28 00:00:00.000'
 ;

@Aaron Bertrand has blogged about this at: What do BETWEEN and the devil have in common?

The command ./manage.py sqlclear or ./manage.py sqlflush seems to clear the table and not delete them, however if you want to delete the complete database try this : manage.py flush.

Warning: this will delete your database completely and you will lose all your data, so if that not important go ahead and try it.

}

Websockets use sockets in their implementation. Websockets are based on a standard protocol (now in final call, but not yet final) that defines a connection "handshake" and message "frame." The two sides go through the handshake procedure to mutually accept a connection and then use the standard message format ("frame") to pass messages back and forth.

I'm developing a framework that will allow you to communicate directly machine to machine with installed software. It might suit your purpose. You can follow my blog if you wish: http://highlevellogic.blogspot.com/2011/09/websocket-server-demonstration_26.html

Since you only wish for the root activity to be reshown when the app is launched, maybe you can get this behavior by changing launch modes, etc. in the manifest?

For instance, have you tried applying the android:clearTaskOnLaunch="true" attribute to your launch activity, perhaps in tandem with android:launchMode="singleInstance"?

Tasks and Back Stack is a great resource for fine-tuning this sort of behavior.

In your notebook (simple approach). Add new cell with following code

%%html

.CodeMirror{
    font-size: 12px;
}

div.output_area pre {
    font-size: 12px;
}
</style>

Somewhere in that mess, the non-breaking spaces from the HTML template (the  s) are encoding as ISO-8859-1 so that they show up incorrectly as an "Â" character

That'd be encoding to UTF-8 then, not ISO-8859-1. The non-breaking space character is byte 0xA0 in ISO-8859-1; when encoded to UTF-8 it'd be 0xC2,0xA0, which, if you (incorrectly) view it as ISO-8859-1 comes out as " ". That includes a trailing nbsp which you might not be noticing; if that byte isn't there, then something else has mauled your document and we need to see further up to find out what.

What's the regexp, how does the templating work? There would seem to be a proper HTML parser involved somewhere if your   strings are (correctly) being turned into U+00A0 NON-BREAKING SPACE characters. If so, you could just process your template natively in the DOM, and ask it to serialise using the ASCII encoding to keep non-ASCII characters as character references. That would also stop you having to do regex post-processing on the HTML itself, which is always a highly dodgy business.

Well anyway, for now you can add one of the following to your document's <head> and see if that makes it look right in the browser:

• for HTML4: <meta http-equiv="Content-Type" content="text/html;charset=utf-8" />
• for HTML5: <meta charset="utf-8">

If you've done that, then any remaining problem is ActivePDF's fault.

JChronic is your best choice. Here's an example that adds a .fromString() method to the Date class that parses just about anything you can throw at it:

Date.metaClass.'static'.fromString = { str ->
    com.mdimension.jchronic.Chronic.parse(str).beginCalendar.time
}

You can call it like this:

println Date.fromString("Tue Aug 10 16:02:43 PST 2010")
println Date.fromString("july 1, 2012")
println Date.fromString("next tuesday")

When leaving the current page, the CollectionView associated with the ItemsSource property of the ComboBox is purged. And because the ComboBox IsSyncronizedWithCurrent property is true by default, the SelectedItem and SelectedValue properties are reset.
This seems to be an internal data type issue in the binding. As others suggested above, if you use SelectedValue instead by binding to an int property on the viewmodel, it will work. A shortcut for you would be to override the Equals operator on MyObject so that when comparing two MyObjects, the actual Id properties are compared.

Another hint: If you do restructure your viewmodels and use SelectedValue, use it only when SelectedValuePath=Id where Id is int. If using a string key, bind to the Text property of the ComboBox instead of SelectedValue.

For the arrow color, you can use this:

.tooltip .tooltip-arrow {border-top: 5px solid red !important;}

If you are writing a web app or single page application (SPA) where routing takes place in the app/browser rather than a round-trip to the server, you can do the following:

window.history.pushState({ prevUrl: window.location.href }, null, "/new/path/in/your/app")

Then, in your new route, you can do the following to retrieve the previous URL:

window.history.state.prevUrl // your previous url

Try Character.getNumericValue(char).

String element = "el5";
int x = Character.getNumericValue(element.charAt(2));
System.out.println("x=" + x);

produces:

x=5

The nice thing about getNumericValue(char) is that it also works with strings like "el?" and "el?" where ? and ? are the digits 5 in Eastern Arabic and Hindi/Sanskrit respectively.

This will mess with the original list and also needs to be called outside of the loop. Also you don't want to perform a reverse every time you loop - would that be true if one of the Iterables.reverse ideas was applied?

Collections.reverse(stringList);

for(String string: stringList){
//...do something
}

Try these steps: 1- click on Import project (Eclipse, ADT, ...)

2- Choose main directory of your Eclipse project

3- Keep the defaults. The first two options is for changing jar files into remote libraries (dependencies). It mean while building Android studio try to find library in local system or remote repositories. The last option is for showing only one folder as app after importing.

4- Then, you will see the summary of changes

5- Then, if you see Gradle project sync failed, you should go to project view (top left corner). Then, you should go to your project-> app and open build.gradle.

6- Then, you should change your compilesdkVersion and targetsdkVersion to your current version that you see in buildToolsVersion (mine is 23). For example, in my project I should change 17 to 23 in two places

7- If you see an error in your dependencies, you should change the version of it. For example, in my project I need to check which version of android support library I am using. So, I open the SDK manager and go to bottom to see the version. Then, I should replace my Android studio version with my current version and click try again from top right corner

I hope it helps.

Set your Rgui preferences for a large number of lines, then timestamp and save as file at suitable intervals.

• Changing Values:
  • array_map cannot change the values inside input array(s) while array_walk can; in particular, array_map never changes its arguments.
• Array Keys Access:
  • array_map cannot operate with the array keys, array_walk can.
• Return Value:
  • array_map returns a new array, array_walk only returns true. Hence, if you don't want to create an array as a result of traversing one array, you should use array_walk.
• Iterating Multiple Arrays:
  • array_map also can receive an arbitrary number of arrays and it can iterate over them in parallel, while array_walk operates only on one.
• Passing Arbitrary Data to Callback:
  • array_walk can receive an extra arbitrary parameter to pass to the callback. This mostly irrelevant since PHP 5.3 (when anonymous functions were introduced).
• Length of Returned Array:
  • The resulting array of array_map has the same length as that of the largest input array; array_walk does not return an array but at the same time it cannot alter the number of elements of original array; array_filter picks only a subset of the elements of the array according to a filtering function. It does preserve the keys.

Example:

<pre>
<?php

$origarray1 = array(2.4, 2.6, 3.5);
$origarray2 = array(2.4, 2.6, 3.5);

print_r(array_map('floor', $origarray1)); // $origarray1 stays the same

// changes $origarray2
array_walk($origarray2, function (&$v, $k) { $v = floor($v); }); 
print_r($origarray2);

// this is a more proper use of array_walk
array_walk($origarray1, function ($v, $k) { echo "$k => $v", "\n"; });

// array_map accepts several arrays
print_r(
    array_map(function ($a, $b) { return $a * $b; }, $origarray1, $origarray2)
);

// select only elements that are > 2.5
print_r(
    array_filter($origarray1, function ($a) { return $a > 2.5; })
);

?>
</pre>

Result:

Array
(
    [0] => 2
    [1] => 2
    [2] => 3
)
Array
(
    [0] => 2
    [1] => 2

You should explore Json.Net, quite easy to use and allows Json objects to be deserialized in Dictionary directly.

james_newtonking

example:

string json = @"{""key1"":""value1"",""key2"":""value2""}";
Dictionary<string, string> values = JsonConvert.DeserializeObject<Dictionary<string, string>>(json); 
Console.WriteLine(values.Count);
// 2
Console.WriteLine(values["key1"]);
// value1

EventArgs e is a parameter called e that contains the event data, see the EventArgs MSDN page for more information.

Object Sender is a parameter called Sender that contains a reference to the control/object that raised the event.

Event Arg Class: http://msdn.microsoft.com/en-us/library/system.eventargs.aspx

Example:

protected void btn_Click (object sender, EventArgs e){
   Button btn = sender as Button;
   btn.Text = "clicked!";
}

Edit: When Button is clicked, the btn_Click event handler will be fired. The "object sender" portion will be a reference to the button which was clicked

Hash-Map stores the (key,value) pair as the Map.Entry Type.As you know that Hash-Map uses Linked Hash-Map(In case Collision occurs). Therefore each Node in the Bucket of Hash-Map is of Type Map.Entry. So whenever you iterate through the Hash-Map you will get Nodes of Type Map.Entry.

Now in your example when you are iterating through the Hash-Map, you will get Map.Entry Type(Which is Interface), To get the Key and Value from this Map.Entry Node Object, interface provided methods like getValue(), getKey() etc. So as per the code, In your Object you are adding all operators JButtons viz (+,-,/,*,=).

A jQuery solution, but it is still a bit better for those who want to change the button text as well:

$(function(){_x000D_
  $("#showHide").click(function(){_x000D_
    var btn = $(this);_x000D_
    $("#content").toggle(function () {_x000D_
      btn.text($(this).css("display") === 'none' ? "Show" : "Hide");_x000D_
    });_x000D_
   });_x000D_
 });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_

  What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged._x000D_

You should first add a new route in global.asax:

routes.MapRoute(
                "MyNewRoute",
                "{controller}/{action}/{date}",
                new { controller="YourControllerName", action="YourActionName", date = "" }
            );

The on your Controller:

        public ActionResult MyActionName(DateTime date)
        {

        }

Remember to keep your default route at the bottom of the RegisterRoutes method. Be advised that the engine will try to cast whatever value you send in {date} as a DateTime example, so if it can't be casted then an exception will be thrown. If your date string contains spaces or : you could HTML.Encode them so the URL could be parsed correctly. If no, then you could have another DateTime representation.

There are several ways to try to prevent line breaks, and the phrase “a newer construct” might refer to more than one way—that’s actually the most reasonable interpretation. They probably mostly think of the CSS declaration white-space:nowrap and possibly the no-break space character. The different ways are not equivalent, far from that, both in theory and especially in practice, though in some given case, different ways might produce the same result.

There is probably nothing real to be gained by switching from the HTML attribute to the somewhat clumsier CSS way, and you would surely lose when style sheets are disabled. But even the nowrap attribute does no work in all situations. In general, what works most widely is the nobr markup, which has never made its way to any specifications but is alive and kicking: <td><nobr>...</nobr></td>.

Basically, you iterate over files under the given path, subtract the CreationTime of each file found from the current time, and compare against the Days property of the result. The -WhatIf switch will tell you what will happen without actually deleting the files (which files will be deleted), remove the switch to actually delete the files:

$old = 15
$now = Get-Date

Get-ChildItem $path -Recurse |
Where-Object {-not $_.PSIsContainer -and $now.Subtract($_.CreationTime).Days -gt $old } |
Remove-Item -WhatIf

$dbc is returning false. Your query has an error in it:

SELECT users.*, profile.* --You do not join with profile anywhere.
                                 FROM users 
                                 INNER JOIN contact_info 
                                 ON contact_info.user_id = users.user_id 
                                 WHERE users.user_id=3");

The fix for this in general has been described by Raveren.

Is this really possible.

Yes.

function a(x) {    // <-- function_x000D_
  function b(y) { // <-- inner function_x000D_
    return x + y; // <-- use variables from outer scope_x000D_
  }_x000D_
  return b;       // <-- you can even return a function._x000D_
}_x000D_
console.log(a(3)(4));

This can occur when you are showing the dialog for a context that no longer exists. A common case - if the 'show dialog' operation is after an asynchronous operation, and during that operation the original activity (that is to be the parent of your dialog) is destroyed. For a good description, see this blog post and comments:

http://dimitar.me/android-displaying-dialogs-from-background-threads/

From the stack trace above, it appears that the facebook library spins off the auth operation asynchronously, and you have a Handler - Callback mechanism (onComplete called on a listener) that could easily create this scenario.

When I've seen this reported in my app, its pretty rare and matches the experience in the blog post. Something went wrong for the activity/it was destroyed during the work of the the AsyncTask. I don't know how your modification could result in this every time, but perhaps you are referencing an Activity as the context for the dialog that is always destroyed by the time your code executes?

Also, while I'm not sure if this is the best way to tell if your activity is running, see this answer for one method of doing so:

Check whether activity is active

You will have to define Serializer Formatter within WebApiConfig.cs available in App_Start Folder like

Adding config.Formatters.Remove(config.Formatters.XmlFormatter); // which will provide you data in JSON Format

Adding config.Formatters.Remove(config.Formatters.JsonFormatter); // which will provide you data in XML Format

After typing "prop" + Tab + Tab as suggested by Amra, you can immediately type the property's type (which will replace the default int), type another tab and type the property name (which will replace the default MyProperty). Finish by pressing Enter.

This answer fails in a couple of edge cases (see comments). The accepted solution above will handle these. str.splitlines() is the way to go. I will leave this answer nevertheless as reference.

Old (incorrect) answer:

s =  \
"""line1
line2
line3
"""

lines = s.split('\n')
print(lines)
for line in lines:
    print(line)

Assume you have one table with name 'table1'. It contain one column 'col1' with varchar type. Query to crate table is give below

CREATE TABLE `table1` (
    `col1` VARCHAR(50) NULL DEFAULT NULL
)

Now if you want to insert number from 1 to 50 in that table then use following stored procedure

CREATE PROCEDURE ABC()

   BEGIN
      DECLARE a INT Default 1 ;
      simple_loop: LOOP         
         insert into table1 values(a);
         SET a=a+1;
         IF a=51 THEN
            LEAVE simple_loop;
         END IF;
   END LOOP simple_loop;
END $$

To call that stored procedure use

CALL `ABC`()

System.Int32.MaxValue

Assuming you mean System.Array, ie. any normally defined array (int[], etc). This is the maximum number of values the array can hold. The size of each value is only limited by the amount of memory or virtual memory available to hold them.

This limit is enforced because System.Array uses an Int32 as it's indexer, hence only valid values for an Int32 can be used. On top of this, only positive values (ie, >= 0) may be used. This means the absolute maximum upper bound on the size of an array is the absolute maximum upper bound on values for an Int32, which is available in Int32.MaxValue and is equivalent to 2^31, or roughly 2 billion.

On a completely different note, if you're worrying about this, it's likely you're using alot of data, either correctly or incorrectly. In this case, I'd look into using a List<T> instead of an array, so that you are only using as much memory as needed. Infact, I'd recommend using a List<T> or another of the generic collection types all the time. This means that only as much memory as you are actually using will be allocated, but you can use it like you would a normal array.

The other collection of note is Dictionary<int, T> which you can use like a normal array too, but will only be populated sparsely. For instance, in the following code, only one element will be created, instead of the 1000 that an array would create:

Dictionary<int, string> foo = new Dictionary<int, string>();
foo[1000] = "Hello world!";
Console.WriteLine(foo[1000]);

Using Dictionary also lets you control the type of the indexer, and allows you to use negative values. For the absolute maximal sized sparse array you could use a Dictionary<ulong, T>, which will provide more potential elements than you could possible think about.

I had this problem when upgrading to Visual Studio 2015 and none of the solutions posted here made any difference, although the config is right the location for the change is not. I fixed this issue by adding this configuration:

<startup useLegacyV2RuntimeActivationPolicy="true">
</startup>

To: C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\CommonExtensions\Microsoft\TestWindow\TE.ProcessHost.Managed.exe.config

Then restarted Visual Studio.

To apply J. B. Rainsberger and sschaef's comments to specifically answer the question... To use a cherry-pick range on this example:

git checkout a
git cherry-pick b..f

or

git checkout a
git cherry-pick c^..f

One issue with REPLACE will be where city names contain the district name. You can use something like.

SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM   dbo.tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004' 

Yes, it's possible:

public void myMethod(int... numbers) { /* your code */ }

In [34]: a=np.arange(-10,10)

In [35]: a
Out[35]:
array([-10,  -9,  -8,  -7,  -6,  -5,  -4,  -3,  -2,  -1,   0,   1,   2,
         3,   4,   5,   6,   7,   8,   9])

In [36]: np.where(a>5)
Out[36]: (array([16, 17, 18, 19]),)

In [37]: np.where(a>5)[0][0]
Out[37]: 16

You can use VBScript regular expression features using OLE Automation. This is way better than the overhead of creating and maintaining an assembly. Please make sure you go through the comments section to get a better modified version of the main one.

DECLARE @obj INT, @res INT, @match BIT;
DECLARE @pattern varchar(255) = '<your regex pattern goes here>';
DECLARE @matchstring varchar(8000) = '<string to search goes here>';
SET @match = 0;

-- Create a VB script component object
EXEC @res = sp_OACreate 'VBScript.RegExp', @obj OUT;

-- Apply/set the pattern to the RegEx object
EXEC @res = sp_OASetProperty @obj, 'Pattern', @pattern;

-- Set any other settings/properties here
EXEC @res = sp_OASetProperty @obj, 'IgnoreCase', 1;

-- Call the method 'Test' to find a match
EXEC @res = sp_OAMethod @obj, 'Test', @match OUT, @matchstring;

-- Don't forget to clean-up
EXEC @res = sp_OADestroy @obj;

If you get SQL Server blocked access to procedure 'sys.sp_OACreate'... error, use sp_reconfigure to enable Ole Automation Procedures. (Yes, unfortunately that is a server level change!)

Happy coding

If the user clicks Cancel, a zero-length string is returned. You can't differentiate this from entering an empty string. You can however make your own custom InputBox class...

EDIT to properly differentiate between empty string and cancel, according to this answer.

Your example

Private Sub test()
    Dim result As String
    result = InputBox("Enter Date MM/DD/YYY", "Date Confirmation", Now)
    If StrPtr(result) = 0 Then
        MsgBox ("User canceled!")
    ElseIf result = vbNullString Then
        MsgBox ("User didn't enter anything!")
    Else
        MsgBox ("User entered " & result)
    End If
End Sub

Would tell the user they canceled when they delete the default string, or they click cancel.

In iOS 7 you must use the -barTintColor property:

navController.navigationBar.barTintColor = [UIColor barColor];

The in operator only works on objects. You are using it on a string. Make sure your value is an object before you using $.each. In this specific case, you have to parse the JSON:

$.each(JSON.parse(myData), ...);

You can proceed as follow:

1. Install Charles Web Proxy.
2. Disable SSL proxying (uncheck the flag in Proxy->Proxy Settings...->SSL
3. Connect your iDevice to the Charles proxy, as explained here
4. Sniff the packets via Wireshark or Charles

On a system with both Python 2 and 3 installed and with pip2-installed Pillow failing to provide Image, it is possible to install PIL for Python 2 in a way that will solve ImportError: No module named Image:

easy_install-2.7 --user PIL

or

sudo easy_install-2.7 PIL

I had this problem in MacOS, and I solved it by linking the brew installed python 3 version, with

brew link python3

After that, it worked without a problem.

Instead of having to specify a locale in all parses, I prefer to set an application wide locale, although if string formats are not consistent across the app, this might not work.

CultureInfo.DefaultThreadCurrentCulture = new CultureInfo("pt-PT");
CultureInfo.DefaultThreadCurrentUICulture = new CultureInfo("pt-PT");

Defining this at the begining of your application will make all double parses expect a comma as the decimal delimiter. You can set an appropriate locale so that the decimal and thousands separator fits the strings you are parsing.

What is Continuous Integration Continuous Integration is a process or a development practice of automated build and automated test i.e. A developer is required to commit his code multiple times into a shared repository where each integration is verified by automated build and test.

If the build fails/success it is notified to a developer and then he can take relevant actions.

What is Continuous Delivery Continuous Delivery is the practise where we keep our code deployable at any point which has passed all the test and has all the required configuration to push the code to production but hasn’t been deployed yet.

What is Continuous Deployment With the help of CI we have created s build for our application and is ready to push to production. In this step our build is ready and with CD we can deploy our application directly to QA environment and if everything goes well we can deploy the same build to production.

So basically, Continuous deployment is one step further than continuous delivery. With this practice, every change which passes all stages of your production pipeline is released to your customers.

Continuous Deployment is a combination of Configuration Management and Containerization.

Configuration Management: CM is all about maintaining the configuration of server which will be compatible to application requirement.

Containerization: Containerization is a set of tolls which will maintain consistency across the environment.

If you're doing this to several fields, or doing it quite often, then perhaps a plugin is the answer.
Here's the beginnings of a jQuery plugin that formats the value of a field to two decimal places.
It is triggered by the onchange event of the field. You may want something different.

<script type="text/javascript">

    // mini jQuery plugin that formats to two decimal places
    (function($) {
        $.fn.currencyFormat = function() {
            this.each( function( i ) {
                $(this).change( function( e ){
                    if( isNaN( parseFloat( this.value ) ) ) return;
                    this.value = parseFloat(this.value).toFixed(2);
                });
            });
            return this; //for chaining
        }
    })( jQuery );

    // apply the currencyFormat behaviour to elements with 'currency' as their class
    $( function() {
        $('.currency').currencyFormat();
    });

</script>   
<input type="text" name="one" class="currency"><br>
<input type="text" name="two" class="currency">

Swift 3.0 and ios 10 or older

func phone(phoneNum: String) {
    if let url = URL(string: "tel://\(phoneNum)") {
        if #available(iOS 10, *) {
            UIApplication.shared.open(url, options: [:], completionHandler: nil)
        } else {

The problem is that you are trying to insert data into the database without using columns. Sql server gives you that error message.

error: insert into users values('1', '2','3') - this works fine as long you only have 3 columns

if you have 4 columns but only want to insert into 3 of them

correct: insert into users (firstName,lastName,city) values ('Tom', 'Jones', 'Miami')

hope this helps

An application bundle (a .app file) is actually a bunch of directories. Instead of using open and the .app name, you can actually move in to it and start the actual binary. For instance:

$ cd /Applications/LittleSnapper.app/
$ ls
Contents
$ cd Contents/MacOS/
$ ./LittleSnapper

That is the actual binary that might accept arguments (or not, in LittleSnapper's case).

Not exactly what I wanted, but I found a workaround. In Eclipse 3.4 (Ganymede), go to

Window->Preferences->Java->Editor->Content Assist

and check the checkbox for Use static imports (only 1.5 or higher).

This will not bring in the import on an Optimize Imports, but if you do a Quick Fix (CTRL + 1) on the line it will give you the option to add the static import which is good enough.

How do you change your cursor to the finger (like for clicking on links) instead of the regular pointer?

This is very simple to achieve using the CSS property cursor, no jQuery needed.

You can read more about in: CSS cursor property and cursor - CSS | MDN

.default {_x000D_
  cursor: default;_x000D_
}_x000D_
.pointer {_x000D_
  cursor: pointer;_x000D_
}

<a class="default" href="#">default</a>_x000D_
_x000D_
<a class="pointer" href="#">pointer</a>

I've generally used xml drawables to create shadow/elevation on a pre-lollipop widget. Here, for example, is an xml drawable that can be used on pre-lollipop devices to simulate the floating action button's elevation.

Lots of great answers diving into the theory of how Ruby's "pass-reference-by-value" works. But I learn and understand everything much better by example. Hopefully, this will be helpful.

def foo(bar)
  puts "bar (#{bar}) entering foo with object_id #{bar.object_id}"
  bar =  "reference"
  puts "bar (#{bar}) leaving foo with object_id #{bar.object_id}"
end

bar = "value"
puts "bar (#{bar}) before foo with object_id #{bar.object_id}"
foo(bar)
puts "bar (#{bar}) after foo with object_id #{bar.object_id}"

# Output
bar (value) before foo with object_id 60
bar (value) entering foo with object_id 60
bar (reference) leaving foo with object_id 80 # <-----
bar (value) after foo with object_id 60 # <-----

As you can see when we entered the method, our bar was still pointing to the string "value". But then we assigned a string object "reference" to bar, which has a new object_id. In this case bar inside of foo, has a different scope, and whatever we passed inside the method, is no longer accessed by bar as we re-assigned it and point it to a new place in memory that holds String "reference".

Now consider this same method. The only difference is what with do inside the method

def foo(bar)
  puts "bar (#{bar}) entering foo with object_id #{bar.object_id}"
  bar.replace "reference"
  puts "bar (#{bar}) leaving foo with object_id #{bar.object_id}"
end

bar = "value"
puts "bar (#{bar}) before foo with object_id #{bar.object_id}"
foo(bar)
puts "bar (#{bar}) after foo with object_id #{bar.object_id}"

# Output
bar (value) before foo with object_id 60
bar (value) entering foo with object_id 60
bar (reference) leaving foo with object_id 60 # <-----
bar (reference) after foo with object_id 60 # <-----

Notice the difference? What we did here was: we modified the contents of the String object, that variable was pointing to. The scope of bar is still different inside of the method.

So be careful how you treat the variable passed into methods. And if you modify passed-in variables-in-place (gsub!, replace, etc), then indicate so in the name of the method with a bang !, like so "def foo!"

P.S.:

It's important to keep in mind that the "bar"s inside and outside of foo, are "different" "bar". Their scope is different. Inside the method, you could rename "bar" to "club" and the result would be the same.

I often see variables re-used inside and outside of methods, and while it's fine, it takes away from the readability of the code and is a code smell IMHO. I highly recommend not to do what I did in my example above :) and rather do this

def foo(fiz)
  puts "fiz (#{fiz}) entering foo with object_id #{fiz.object_id}"
  fiz =  "reference"
  puts "fiz (#{fiz}) leaving foo with object_id #{fiz.object_id}"
end

bar = "value"
puts "bar (#{bar}) before foo with object_id #{bar.object_id}"
foo(bar)
puts "bar (#{bar}) after foo with object_id #{bar.object_id}"

# Output
bar (value) before foo with object_id 60
fiz (value) entering foo with object_id 60
fiz (reference) leaving foo with object_id 80
bar (value) after foo with object_id 60

As was indicated by others, you don't need to use malloc just to do:

const char *foo = "bar";

The reason for that is exactly that *foo is a pointer — when you initialize foo you're not creating a copy of the string, just a pointer to where "bar" lives in the data section of your executable. You can copy that pointer as often as you'd like, but remember, they're always pointing back to the same single instance of that string.

So when should you use malloc? Normally you use strdup() to copy a string, which handles the malloc in the background. e.g.

const char *foo = "bar";
char *bar = strdup(foo); /* now contains a new copy of "bar" */
printf("%s\n", bar);     /* prints "bar" */
free(bar);               /* frees memory created by strdup */

Now, we finally get around to a case where you may want to malloc if you're using sprintf() or, more safely snprintf() which creates / formats a new string.

char *foo = malloc(sizeof(char) * 1024);        /* buffer for 1024 chars */
snprintf(foo, 1024, "%s - %s\n", "foo", "bar"); /* puts "foo - bar\n" in foo */
printf(foo);                                    /* prints "foo - bar" */
free(foo);                                      /* frees mem from malloc */

Well, technically '\0' is a character while "\0" is a string, so if you're checking for the null termination character the former is correct. However, as Chris Lutz points out in his answer, your comparison won't work in it's current form.

OP wants to decrease brightness, not increase it. Opacity makes the image look brighter, not darker.

You can do this by overlaying a black div over the image and setting the opacity of that div.

<style>
#container {
    position: relative;
}
div.overlay {
    opacity: .9;
    background-color: black;
    position: absolute;
    left: 0; top: 0; height: 256px; width: 256px;
}

The HashSet(Of T) class provides high-performance set operations. A set is a collection that contains no duplicate elements, and whose elements are in no particular order...

The capacity of a HashSet(Of T) object is the number of elements that the object can hold. A HashSet(Of T) object's capacity automatically increases as elements are added to the object.

The HashSet(Of T) class is based on the model of mathematical sets and provides high-performance set operations similar to accessing the keys of the Dictionary(Of TKey, TValue) or Hashtable collections. In simple terms, the HashSet(Of T) class can be thought of as a Dictionary(Of TKey, TValue) collection without values.

A HashSet(Of T) collection is not sorted and cannot contain duplicate elements...

Using UIPickerview is the right way to go to implement it according to Apple's Human Interface Guidelines

If you select drop down in mobile safari it will show UIPickerview to let the use choose drop down items.

Alternatively

you can use UIPopoverController till iOS 9 as its deprecated but its better to stick with UIModalPresentationPopover of view you want o show as well

you can use UIActionsheet to show the items but it's better to use UIAlertViewController and choose UIActionSheetstyle to show as the former is deprecated in latest versions

In case anyone is wondering how to use Marionette in C#.

FirefoxProfile profile = new FirefoxProfile(); // Your custom profile
var service = FirefoxDriverService.CreateDefaultService("DirectoryContainingTheDriver", "geckodriver.exe");
// Set the binary path if you want to launch the release version of Firefox.
service.FirefoxBinaryPath = @"C:\Program Files\Mozilla Firefox\firefox.exe";
var option = new FirefoxProfileOptions(profile) { IsMarionette = true };
var driver = new FirefoxDriver(
    service,
    option,
    TimeSpan.FromSeconds(30));

Overriding FirefoxOptions to provide the function to add additional capability and set Firefox profile because selenium v53 doesn't provide that function yet.

public class FirefoxProfileOptions : FirefoxOptions
{
    private DesiredCapabilities _capabilities;

    public FirefoxProfileOptions()
        : base()
    {
        _capabilities = DesiredCapabilities.Firefox();
        _capabilities.SetCapability("marionette", this.IsMarionette);
    }

    public FirefoxProfileOptions(FirefoxProfile profile)
        : this()
    {
        _capabilities.SetCapability(FirefoxDriver.ProfileCapabilityName, profile.ToBase64String());
    }

    public override void AddAdditionalCapability(string capabilityName, object capabilityValue)
    {
        _capabilities.SetCapability(capabilityName, capabilityValue);
    }

    public override ICapabilities ToCapabilities()
    {
        return _capabilities;
    }
}

Note: Launching with profile doesn't work with FF 47, it works with FF 50 Nightly.

However, we tried to convert our test to use Marionette, and it's just not viable at the moment because the implementation of the driver is either not completed or buggy. I'd suggest people downgrade their Firefox at this moment.

First of all: officially, the correct question would be web services + WSDL + SOAP vs REST.

Because, although the web service, is used in the loose sense, when using the HTTP protocol to transfer data instead of web pages, officially it is a very specific form of that idea. According to the definition, REST is not "web service".

In practice however, everyone ignores that, so let's ignore it too

There are already technical answers, so I'll try to provide some intuition.

Let's say you want to call a function in a remote computer, implemented in some other programming language (this is often called remote procedure call/RPC). Assume that function can be found at a specific URL, provided by the person who wrote it. You have to (somehow) send it a message, and get some response. So, there are two main questions to consider.

• what is the format of the message you should send
• how should the message be carried back and forth

For the first question, the official definition is WSDL. This is an XML file which describes, in detailed and strict format, what are the parameters, what are their types, names, default values, the name of the function to be called, etc. An example WSDL here shows that the file is human-readable (but not easily).

For the second question, there are various answers. However, the only one used in practice is SOAP. Its main idea is: wrap the previous XML (the actual message) into yet another XML (containing encoding info and other helpful stuff), and send it over HTTP. The POST method of the HTTP is used to send the message, since there is always a body.

The main idea of this whole approach is that you map a URL to a function, that is, to an action. So, if you have a list of customers in some server, and you want to view/update/delete one, you must have 3 URLS:

• myapp/read-customer and in the body of the message, pass the id of the customer to be read.
• myapp/update-customer and in the body, pass the id of the customer, as well as the new data
• myapp/delete-customer and the id in the body

The REST approach sees things differently. A URL should not represent an action, but a thing (called resource in the REST lingo). Since the HTTP protocol (which we are already using) supports verbs, use those verbs to specify what actions to perform on the thing.

So, with the REST approach, customer number 12 would be found on URL myapp/customers/12. To view the customer data, you hit the URL with a GET request. To delete it, the same URL, with a DELETE verb. To update it, again, the same URL with a POST verb, and the new content in the request body.

For more details about the requirements that a service has to fulfil to be considered truly RESTful, see the Richardson maturity model. The article gives examples, and, more importantly, explains why a (so-called) SOAP service, is a level-0 REST service (although, level-0 means low compliance to this model, it's not offensive, and it is still useful in many cases).

State machines are very simple in C if you use function pointers.

Basically you need 2 arrays - one for state function pointers and one for state transition rules. Every state function returns the code, you lookup state transition table by state and return code to find the next state and then just execute it.

int entry_state(void);
int foo_state(void);
int bar_state(void);
int exit_state(void);

/* array and enum below must be in sync! */
int (* state[])(void) = { entry_state, foo_state, bar_state, exit_state};
enum state_codes { entry, foo, bar, end};

enum ret_codes { ok, fail, repeat};
struct transition {
    enum state_codes src_state;
    enum ret_codes   ret_code;
    enum state_codes dst_state;
};
/* transitions from end state aren't needed */
struct transition state_transitions[] = {
    {entry, ok,     foo},
    {entry, fail,   end},
    {foo,   ok,     bar},
    {foo,   fail,   end},
    {foo,   repeat, foo},
    {bar,   ok,     end},
    {bar,   fail,   end},
    {bar,   repeat, foo}};

#define EXIT_STATE end
#define ENTRY_STATE entry

int main(int argc, char *argv[]) {
    enum state_codes cur_state = ENTRY_STATE;
    enum ret_codes rc;
    int (* state_fun)(void);

    for (;;) {
        state_fun = state[cur_state];
        rc = state_fun();
        if (EXIT_STATE == cur_state)
            break;
        cur_state = lookup_transitions(cur_state, rc);
    }

    return EXIT_SUCCESS;
}

I don't put lookup_transitions() function as it is trivial.

That's the way I do state machines for years.

Well, for your sample and any with a limited number of unique columns, this should do it.

select 
    distinct a,
    (select distinct t2.b  from t t2  where t1.a=t2.a and t2.b='VIEW'),
    (select distinct t2.b from t t2  where t1.a=t2.a and t2.b='EDIT')
from t t1

This is similar to the scripts we generate on our team. Create the table first, then apply pk/fk and other constraints.

CREATE TABLE [dbo].[ImagenesUsuario] (
    [idImagen] [int] IDENTITY (1, 1) NOT NULL
)

ALTER TABLE [dbo].[ImagenesUsuario] ADD 
    CONSTRAINT [PK_ImagenesUsuario] PRIMARY KEY  CLUSTERED 
    (
        [idImagen]
    )  ON [PRIMARY] 

We can use assert here.

def _input(inp_str:str):
    try:
        assert len(inp_str)<=15,print('More than 15 characters present')
        assert all('a'<=i<='z' for i in inp_str),print('Characters other than "a"-"z" are found')
        return inp_str
    except Exception as e:
        pass

_input('abcd')
#abcd
_input('abc d')
#Characters other than "a"-"z" are found
_input('abcdefghijklmnopqrst')
#More than 15 characters present

In my project this seems to work:

function isDate($value) {
    if (!$value) {
        return false;
    } else {
        $date = date_parse($value);
        if($date['error_count'] == 0 && $date['warning_count'] == 0){
            return checkdate($date['month'], $date['day'], $date['year']);
        } else {
            return false;
        }
    }
}

Here's an answer regarding the XML configuration, note that if you don't give the file appender a ConversionPattern it will create 0 byte file and not write anything:

May this could helpful for some people. I had a naughty error: undefined reference to symbol '_ZN5boost6system15system_categoryEv' //usr/lib/x86_64-linux-gnu/libboost_system.so.1.58.0: error adding symbols: DSO missing from command line There were some issue of cmakeList.txt and somehow I was missing to explicitly include the "system" and "filesystem" libraries. So, I wrote these lines in CMakeLists.txt

These lines are written at the beginning before creating the executable of the project, as at this stage we don't need to link boost library to our project executable.

set(Boost_USE_STATIC_LIBS OFF) 
set(Boost_USE_MULTITHREADED ON)  
set(Boost_USE_STATIC_RUNTIME OFF) 
set(Boost_NO_SYSTEM_PATHS TRUE) 

if (Boost_NO_SYSTEM_PATHS)
  set(BOOST_ROOT "${CMAKE_CURRENT_SOURCE_DIR}/../../3p/boost")
  set(BOOST_INCLUDE_DIRS "${BOOST_ROOT}/include")
  set(BOOST_LIBRARY_DIRS "${BOOST_ROOT}/lib")
endif (Boost_NO_SYSTEM_PATHS)


find_package(Boost COMPONENTS regex date_time system filesystem thread graph program_options) 

find_package(Boost REQUIRED regex date_time system filesystem thread graph program_options)
find_package(Boost COMPONENTS program_options REQUIRED)

Now at the end of the file, I wrote these lines by considering "KeyPointEvaluation" as my project executable.

if(Boost_FOUND)
    include_directories(${BOOST_INCLUDE_DIRS})
    link_directories(${Boost_LIBRARY_DIRS})
    add_definitions(${Boost_DEFINITIONS})

    include_directories(${Boost_INCLUDE_DIRS})  
    target_link_libraries(KeyPointEvaluation ${Boost_LIBRARIES})
    target_link_libraries( KeyPointEvaluation ${Boost_PROGRAM_OPTIONS_LIBRARY} ${Boost_FILESYSTEM_LIBRARY} ${Boost_REGEX_LIBRARY} ${Boost_SYSTEM_LIBRARY})
endif()

:) Your using the thread in a wrong way. Just do the following:

private void runthread()
{

splashTread = new Thread() {
            @Override
            public void run() {
                try {
                    synchronized(this){

                        //wait 5 sec
                        wait(_splashTime);
                    }

                } catch(InterruptedException e) {}
                finally {
                    //call the handler to set the text
                }
            }
        };

        splashTread.start(); 
}

That's it.

You're not loading the validation plugin. You need:

<script src="http://ajax.aspnetcdn.com/ajax/jquery.validate/1.11.1/jquery.validate.min.js"></script>

Put this before the line that loads the additional methods.

Also, you should get the additional methods from the CDN as well, rather than jquery.bassistance.de.

For that ratio of read/writes I would guess InnoDB will perform better. Since you are fine with dirty reads, you might (if you afford) replicate to a slave and let all your reads go to the slave. Also, consider inserting in bulk, rather than one record at a time.

I discovered while following the above suggestions that for line in f: does not work for a pandas dataframe (not that anyone said it would) because the end of file in a dataframe is the last column, not the last row. for example if you have a data frame with 3 fields (columns) and 9 records (rows), the for loop will stop after the 3rd iteration, not after the 9th iteration.

Allocate memory before using the pointer. If you don't allocate memory *point = 12 is undefined behavior.

int *fun()
{
    int *point = malloc(sizeof *point); /* Mandatory. */
    *point=12;  
    return point;
}

Also your printf is wrong. You need to dereference (*) the pointer.

printf("%d", *ptr);
             ^

• Platform.runLater: If you need to update a GUI component from a non-GUI thread, you can use that to put your update in a queue and it will be handled by the GUI thread as soon as possible.
• Task implements the Worker interface which is used when you need to run a long task outside the GUI thread (to avoid freezing your application) but still need to interact with the GUI at some stage.

If you are familiar with Swing, the former is equivalent to SwingUtilities.invokeLater and the latter to the concept of SwingWorker.

The javadoc of Task gives many examples which should clarify how they can be used. You can also refer to the tutorial on concurrency.

There is an implicit call to super() with no arguments for all classes that have a parent - which is every user defined class in Java - so calling it explicitly is usually not required. However, you may use the call to super() with arguments if the parent's constructor takes parameters, and you wish to specify them. Moreover, if the parent's constructor takes parameters, and it has no default parameter-less constructor, you will need to call super() with argument(s).

An example, where the explicit call to super() gives you some extra control over the title of the frame:

class MyFrame extends JFrame
{
    public MyFrame() {
        super("My Window Title");
        ...
    }
}

Try changing the color of your "border-top" attribute to white

If you'd like the download to be offered as a download that can be opened directly in Excel, this may work for you: (copied from an old unreleased project of mine)

These functions setup the headers:

function setExcelContentType() {
    if(headers_sent())
        return false;

    header('Content-type: application/vnd.ms-excel');
    return true;
}

function setDownloadAsHeader($filename) {
    if(headers_sent())
        return false;

    header('Content-disposition: attachment; filename=' . $filename);
    return true;
}

This one sends a CSV to a stream using a mysql result

function csvFromResult($stream, $result, $showColumnHeaders = true) {
    if($showColumnHeaders) {
        $columnHeaders = array();
        $nfields = mysql_num_fields($result);
        for($i = 0; $i < $nfields; $i++) {
            $field = mysql_fetch_field($result, $i);
            $columnHeaders[] = $field->name;
        }
        fputcsv($stream, $columnHeaders);
    }

    $nrows = 0;
    while($row = mysql_fetch_row($result)) {
        fputcsv($stream, $row);
        $nrows++;
    }

    return $nrows;
}

This one uses the above function to write a CSV to a file, given by $filename

function csvFileFromResult($filename, $result, $showColumnHeaders = true) {
    $fp = fopen($filename, 'w');
    $rc = csvFromResult($fp, $result, $showColumnHeaders);
    fclose($fp);
    return $rc;
}

And this is where the magic happens ;)

function csvToExcelDownloadFromResult($result, $showColumnHeaders = true, $asFilename = 'data.csv') {
    setExcelContentType();
    setDownloadAsHeader($asFilename);
    return csvFileFromResult('php://output', $result, $showColumnHeaders);
}

For example:

$result = mysql_query("SELECT foo, bar, shazbot FROM baz WHERE boo = 'foo'");
csvToExcelDownloadFromResult($result);

To get a position of an element in a vector knowing an iterator pointing to the element, simply subtract v.begin() from the iterator:

ptrdiff_t pos = find(Names.begin(), Names.end(), old_name_) - Names.begin();

Now you need to check pos against Names.size() to see if it is out of bounds or not:

if(pos >= Names.size()) {
    //old_name_ not found
}

vector iterators behave in ways similar to array pointers; most of what you know about pointer arithmetic can be applied to vector iterators as well.

Starting with C++11 you can use std::distance in place of subtraction for both iterators and pointers:

ptrdiff_t pos = distance(Names.begin(), find(Names.begin(), Names.end(), old_name_));

When in doubt just place it in the root of your repository. See https://help.github.com/articles/ignoring-files/ for more information.

you can use if statement like below

select CONCAT(if(affiliate_name is null ,'',affiliate_name),'- ',if(model is null ,'',affiliate_name)) as model from devices

$name = str_replace(' ', '_', $name);

Use Cygwin Bash with:

Solution using just POST - no $_SESSION

page1.php

<form action="page2.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>

page2.php

<?php
    // this page outputs the contents of the textarea if posted
    $textarea1 = ""; // set var to avoid errors
    if(isset($_POST['textarea1'])){
        $textarea1 = $_POST['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

Solution using $_SESSION and POST

page1.php

<?php

    session_start(); // needs to be before anything else on page to use $_SESSION
    $textarea1 = "";
    if(isset($_POST['textarea1'])){
        $_SESSION['textarea1'] = $_POST['textarea1'];
    }

?>


<form action="page1.php" method="post">
    <textarea name="textarea1" id="textarea1"></textarea><br />
    <input type="submit" value="submit" />
</form>
<br /><br />
<a href="page2.php">Go to page2</a>

page2.php

<?php
    session_start(); // needs to be before anything else on page to use $_SESSION
    // this page outputs the textarea1 from the session IF it exists
    $textarea1 = ""; // set var to avoid errors
    if(isset($_SESSION['textarea1'])){
        $textarea1 = $_SESSION['textarea1']
    }
?>
<textarea><?php echo $textarea1;?></textarea>

WARNING!!! - This contains no validation!!!

Take a look at following Redis Cheat Sheet. To get a subset of redis keys with the redis-cli i use the command

KEYS "prefix:*"

Parameters in the URL are GET parameters, a request body, if present, is POST data. So your basic premise is by definition not achievable.

You should choose whether to use POST or GET based on the action. Any destructive action, i.e. something that permanently changes the state of the server (deleting, adding, editing) should always be invoked by POST requests. Any pure "information retrieval" should be accessible via an unchanging URL (i.e. GET requests).

To make a POST request, you need to create a <form>. You could use Javascript to create a POST request instead, but I wouldn't recommend using Javascript for something so basic. If you want your submit button to look like a link, I'd suggest you create a normal form with a normal submit button, then use CSS to restyle the button and/or use Javascript to replace the button with a link that submits the form using Javascript (depending on what reproduces the desired behavior better). That'd be a good example of progressive enhancement.

Here a version which uses BigDecimal instead of double:

public static BigDecimal calculateAverage(final List<Integer> values) {
    int sum = 0;
    if (!values.isEmpty()) {
        for (final Integer v : values) {
            sum += v;
        }
        return new BigDecimal(sum).divide(new BigDecimal(values.size()), 2, RoundingMode.HALF_UP);
    }
    return BigDecimal.ZERO;
}

Just use the formula

120 = (HOUR(A8)*3600+MINUTE(A8)*60+SECOND(A8))/60

Even tried all suggestions, in my case (Office x64 - Visual Studio 2017), the only way to have both access engines on a Office 64x installation so you can use it on Visual Studio and using a 2016+ version of Office, is to install the 2010 version of the Engine.

First install the x64 from this page

https://www.microsoft.com/en-us/download/details.aspx?id=54920

and then the x86 version from this one

https://www.microsoft.com/en-us/download/details.aspx?id=13255

as from this blog: http://dinesql.blogspot.com/2017/10/microsoft-access-database-engine-2016-Redistributable-Setup-you-cannot-install-the-32-bit-version-You-cannot-install-the-64-bit-version.html

You can use JSON.stringify like:

JSON.stringify(new_tweets);

get-windowsfeature | where name -like RSAT-AD-PowerShell | Install-WindowsFeature

I like ggplot too.

Here's one example:

df1 = data.frame(
date_id = c('2017-08-01', '2017-08-02', '2017-08-03', '2017-08-04'),          
nation = c('China', 'USA', 'China', 'USA'), 
value = c(4.0, 5.0, 6.0, 5.5))

ggplot(df1, aes(date_id, value, group=nation, colour=nation))+geom_line()+xlab(label='dates')+ylab(label='value')

In jQuery just use:

$('#tblOne > tbody  > tr').each(function() {...code...});

Using the children selector (>) you will walk over all the children (and not all descendents), example with three rows:

$('table > tbody  > tr').each(function(index, tr) { 
   console.log(index);
   console.log(tr);
});

Result:

0
<tr>
1 
<tr>
2
<tr>

In VanillaJS you can use document.querySelectorAll() and walk over the rows using forEach()

[].forEach.call(document.querySelectorAll('#tblOne > tbody  > tr'), function(index, tr) {
    /* console.log(index); */
    /* console.log(tr); */
});

You can't and shouldn't modify a list while iterating over it. You can solve this by temporarely saving the objects to remove:

List<Object> toRemove = new ArrayList<Object>();
for(Object a: list){
    if(a.getXXX().equalsIgnoreCase("AAA")){
        toRemove.add(a);
    }
}
list.removeAll(toRemove);

Use menu Edit ? Advanced ? Word Wrap in Visual Studio 2003.

Here is a bash script for newer Maven copy and paste it...

# @author Yucca Nel

#!/bin/sh

#This installs maven2 & a default JDK 
sudo apt-get install maven2;

#Makes the /usr/lib/mvn in case...
sudo mkdir -p /usr/lib/mvn;

#Clean out /tmp...
sudo rm -rf /tmp/*;
cd /tmp;

#Update this line to reflect newer versions of maven
wget http://mirrors.powertech.no/www.apache.org/dist//maven/binaries/apache-maven-3.0.3-bin.tar.gz;
tar -xvf ./*gz;

#Move it to where it to logical location
sudo mv /tmp/apache-maven-3.* /usr/lib/mvn/;

#Link the new Maven to the bin... (update for higher/newer version)...
sudo ln -s /usr/lib/mvn/apache-maven-3.0.3/bin/mvn /usr/bin/mvn;

#test
mvn -version;

exit 0;

You would do that by providing a fully qualified name, e.g.:

SELECT tbl_names.id as id, name, section FROM tbl_names, tbl_section WHERE tbl_names.id = tbl_section.id

Which would give you the id of tbl_names

Convert the char to int.

    String name = "admin";
    int ascii = name.toCharArray()[0];

Also :

int ascii = name.charAt(0);

The difference is the value returned to the environment is 0 in the former case and 1 in the latter case:

$ ./prog_with_exit_0
$ echo $?
0
$

and

$ ./prog_with_exit_1
$ echo $?
1
$

Also note that the macros value EXIT_SUCCESS and EXIT_FAILURE used as an argument to exit function are implementation defined but are usually set to respectively 0 and a non-zero number. (POSIX requires EXIT_SUCCESS to be 0). So usually exit(0) means a success and exit(1) a failure.

An exit function call with an argument in main function is equivalent to the statement return with the same argument.

const int is identical to int const, as is true with all scalar types in C. In general, declaring a scalar function parameter as const is not needed, since C's call-by-value semantics mean that any changes to the variable are local to its enclosing function.

As of API 24, sending a file:// URI to another app will throw a FileUriExposedException. Instead, use FileProvider to send a content:// URI:

public File getFile(Context context, String fileName) {
    if (!Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {
        return null;
    }

    File storageDir = context.getExternalFilesDir(null);
    return new File(storageDir, fileName);
}

public Uri getFileUri(Context context, String fileName) {
    File file = getFile(context, fileName);
    return FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", file);
}

You must also define the FileProvider in your manifest:

<provider
    android:name="android.support.v4.content.FileProvider"
    android:authorities="com.mydomain.fileprovider"
    android:exported="false"
    android:grantUriPermissions="true">
    <meta-data
        android:name="android.support.FILE_PROVIDER_PATHS"
        android:resource="@xml/file_paths" />
</provider>

Example file_paths.xml:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-files-path name="name" path="path" />
</paths>

Replace "name" and "path" as appropriate.

To give the PDF viewer access to the file, you also have to add the FLAG_GRANT_READ_URI_PERMISSION flag to the intent:

private void displayPdf(String fileName) {
    Uri uri = getFileUri(this, fileName);

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setDataAndType(uri, "application/pdf");

    // FLAG_GRANT_READ_URI_PERMISSION is needed on API 24+ so the activity opening the file can read it
    intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_GRANT_READ_URI_PERMISSION);

    if (intent.resolveActivity(getPackageManager()) == null) {
        // Show an error
    } else {
        startActivity(intent);
    }
}

See the FileProvider documentation for more details.

I have been waiting to see if Google would open a Keep API. When I discovered Google Tasks, and saw that it had an Android app, web app, and API, I converted over to Tasks. This may not directly answer your question, but it is my solution to the Keep API problem.

Tasks doesn't have a reminder alarm exactly like Keep. I can live without that if I also connect with the Calendar API.

https://developers.google.com/google-apps/tasks/

using(var database=new DatabaseEntities()){}

Don't use using statement. Just write like that

DatabaseEntities database=new DatabaseEntities ();{}

It will work.

For documentation on the using statement see here.

Another example for the C++11 standard:

set<int> data;
data.insert(4);
data.insert(5);

for (const int &number : data)
  cout << number;

Passive event listeners are an emerging web standard, new feature shipped in Chrome 51 that provide a major potential boost to scroll performance. Chrome Release Notes.

It enables developers to opt-in to better scroll performance by eliminating the need for scrolling to block on touch and wheel event listeners.

Problem: All modern browsers have a threaded scrolling feature to permit scrolling to run smoothly even when expensive JavaScript is running, but this optimization is partially defeated by the need to wait for the results of any touchstart and touchmove handlers, which may prevent the scroll entirely by calling preventDefault() on the event.

Solution: {passive: true}

By marking a touch or wheel listener as passive, the developer is promising the handler won't call preventDefault to disable scrolling. This frees the browser up to respond to scrolling immediately without waiting for JavaScript, thus ensuring a reliably smooth scrolling experience for the user.

document.addEventListener("touchstart", function(e) {
    console.log(e.defaultPrevented);  // will be false
    e.preventDefault();   // does nothing since the listener is passive
    console.log(e.defaultPrevented);  // still false
}, Modernizr.passiveeventlisteners ? {passive: true} : false);

DOM Spec , Demo Video , Explainer Doc

If you're OK with using a library that writes the SQL for you, then you can use Upsert (currently Ruby and Python only):

Pet.upsert({:name => 'Jerry'}, :breed => 'beagle')
Pet.upsert({:name => 'Jerry'}, :color => 'brown')

That works across MySQL, Postgres, and SQLite3.

It writes a stored procedure or user-defined function (UDF) in MySQL and Postgres. It uses INSERT OR REPLACE in SQLite3.

Both methods achieve the same purpose, to forego unnecessary db queries. But they use different approaches for efficiency.

The only reason to use either of these methods is when a single large query is preferable to many small queries. Django uses the large query to create models in memory preemptively rather than performing on demand queries against the database.

select_related performs a join with each lookup, but extends the select to include the columns of all joined tables. However this approach has a caveat.

Joins have the potential to multiply the number of rows in a query. When you perform a join over a foreign key or one-to-one field, the number of rows won't increase. However, many-to-many joins do not have this guarantee. So, Django restricts select_related to relations that won't unexpectedly result in a massive join.

The "join in python" for prefetch_related is a little more alarming then it should be. It creates a separate query for each table to be joined. It filters each of these table with a WHERE IN clause, like:

SELECT "credential"."id",
       "credential"."uuid",
       "credential"."identity_id"
FROM   "credential"
WHERE  "credential"."identity_id" IN
    (84706, 48746, 871441, 84713, 76492, 84621, 51472);

Rather than performing a single join with potentially too many rows, each table is split into a separate query.

This is a followup to the font-forge section of @Kurt Pfeifle's answer, specific to Red Hat (and possibly other Linux distros).

1. After opening the PDF and selecting the font you want, you will want to select "File -> Generate Fonts..." option.
2. If there are errors in the file, you can choose to ignore them or save the file and edit them. Most of the errors can be fixed automatically if you click "Fix" enough times.
3. Click "Element -> Font Info...", and "Fontname", "Family Name" and "Name for Humans" are all set to values you like. If not, modify them and save the file somewhere. These names will determine how your font appears on the system.
4. Select your file name and click "Save..."

Once you have your TTF file, you can install it on your system by

1. Copying it to folder /usr/share/fonts (as root)
2. Running fc-cache -f /usr/share/fonts/ (as root)

Another potential cause for this error is Sandbox Mode, which prevents MS Access from running certain statements that are considered unsafe. This can be disabled by setting the following registry key...

HKLM\Software\Microsoft\Office\12.0\Access Connectivity Engine\Engines
    SandboxMode (DWORD Value)

...to either 0 or 2:

SETTING DESCRIPTION
   0    Sandbox mode is disabled at all times.
   1    Sandbox mode is used for Access, but not for non-Access programs.
   2    Sandbox mode is used for non-Access programs, but not for Access.
   3    Sandbox mode is used at all times. This is the default value.

Is it possible to use a .netrc file on Windows?

Yes: You must:

• define environment variable %HOME% (pre-Git 2.0, no longer needed with Git 2.0+)
• put a _netrc file in %HOME%

If you are using Windows 7/10, in a CMD session, type:

setx HOME %USERPROFILE%

and the %HOME% will be set to 'C:\Users\"username"'.
Go that that folder (cd %HOME%) and make a file called '_netrc'

Note: Again, for Windows, you need a '_netrc' file, not a '.netrc' file.

Its content is quite standard (Replace the <examples> with your values):

machine <hostname1>
login <login1>

Luke mentions in the comments:

Using the latest version of msysgit on Windows 7, I did not need to set the HOME environment variable. The _netrc file alone did the trick.

This is indeed what I mentioned in "Trying to “install” github, .ssh dir not there":
git-cmd.bat included in msysgit does set the %HOME% environment variable:

@if not exist "%HOME%" @set HOME=%HOMEDRIVE%%HOMEPATH%
@if not exist "%HOME%" @set HOME=%USERPROFILE%

??? believes in the comments that "it seems that it won't work for http protocol"

However, I answered that netrc is used by curl, and works for HTTP protocol, as shown in this example (look for 'netrc' in the page): . Also used with HTTP protocol here: "_netrc/.netrc alternative to cURL".

A common trap with with netrc support on Windows is that git will bypass using it if an origin https url specifies a user name.

For example, if your .git/config file contains:

[remote "origin"]
     fetch = +refs/heads/*:refs/remotes/origin/*
     url = https://[email protected]/p/my-project/

Git will not resolve your credentials via _netrc, to fix this remove your username, like so:

[remote "origin"]
     fetch = +refs/heads/*:refs/remotes/origin/*
     url = https://code.google.com/p/my-project/

Alternative solution: With git version 1.7.9+ (January 2012): This answer from Mark Longair details the credential cache mechanism which also allows you to not store your password in plain text as shown below.

With Git 1.8.3 (April 2013):

You now can use an encrypted .netrc (with gpg).
On Windows: %HOME%/_netrc (_, not '.')

A new read-only credential helper (in contrib/) to interact with the .netrc/.authinfo files has been added.

That script would allow you to use gpg-encrypted netrc files, avoiding the issue of having your credentials stored in a plain text file.

Files with the .gpg extension will be decrypted by GPG before parsing.
Multiple -f arguments are OK. They are processed in order, and the first matching entry found is returned via the credential helper protocol.

When no -f option is given, .authinfo.gpg, .netrc.gpg, .authinfo, and .netrc files in your home directory are used in this order.

To enable this credential helper:

git config credential.helper '$shortname -f AUTHFILE1 -f AUTHFILE2'

(Note that Git will prepend "git-credential-" to the helper name and look for it in the path.)

# and if you want lots of debugging info:
git config credential.helper '$shortname -f AUTHFILE -d'

#or to see the files opened and data found:
git config credential.helper '$shortname -f AUTHFILE -v'

See a full example at "Is there a way to skip password typing when using https:// github"

With Git 2.18+ (June 2018), you now can customize the GPG program used to decrypt the encrypted .netrc file.

git-credential-netrc: accept gpg option

git-credential-netrc was hardcoded to decrypt with 'gpg' regardless of the gpg.program option.
This is a problem on distributions like Debian that call modern GnuPG something else, like 'gpg2'

You can define a variable @Result to fill your data in it

DECLARE @Result AS INT

IF EXISTS (SELECT * FROM tblGLUserAccess WHERE GLUserName ='xxxxxxxx') 
SET @Result = 1 
else
SET @Result = 2
