The shiny package provides the convenient functions validate() and need() for checking that variables are both available and valid. need() evaluates an expression. If the expression is not valid, then an error message is returned. If the expression is valid, NULL is returned. One can use this to check if a variable is valid. See ?need for more information.

I suggest defining a function like this:

is.valid <- function(x) {
  require(shiny)
  is.null(need(x, message = FALSE))  
}

This function is.valid() will return FALSE if x is FALSE, NULL, NA, NaN, an empty string "", an empty atomic vector, a vector containing only missing values, a logical vector containing only FALSE, or an object of class try-error. In all other cases, it returns TRUE.

That means, need() (and is.valid()) covers a really broad range of failure cases. Instead of writing:

if (!is.null(x) && !is.na(x) && !is.nan(x)) {
  ...
}

one can write simply:

if (is.valid(x)) {
  ...
}

With the check for class try-error, it can even be used in conjunction with a try() block to silently catch errors: (see https://csgillespie.github.io/efficientR/programming.html#communicating-with-the-user)

bad = try(1 + "1", silent = TRUE)
if (is.valid(bad)) {
  ...
}

SELECT emp.LoginID, emp.JobTitle, emp.BirthDate, emp.ModifiedDate  , 
      CASE  WHEN emp.JobTitle  NOT LIKE '%Document Control%'  THEN emp.JobTitle
            ELSE SUBSTRING(emp.JobTitle,CHARINDEX('Document Control',emp.JobTitle),LEN('Document Control'))
      END 
      ,emp.gender,emp.MaritalStatus
FROM   HumanResources.Employee [emp]
WHERE  JobTitle LIKE '[C-F]%'

If you mean, you want to scroll through multiple items in your stackpanel, try putting a grid around it. By definition, a stackpanel has infinite length.

So try something like this:

   <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
        <StackPanel Width="311">
              <TextBlock Text="{Binding A}" TextWrapping="Wrap" Style="{StaticResource PhoneTextExtraLargeStyle}" FontStretch="Condensed" FontSize="28" />
              <TextBlock Text="{Binding B}" TextWrapping="Wrap" Margin="12,-6,12,0" Style="{StaticResource PhoneTextSubtleStyle}"/>
        </StackPanel>
    </Grid>

You could even make this work with a ScrollViewer

The problem here involves type casting.

When you add int and long,

1. The int object is casted to long & both are added and you get long object.
2. but long object cannot be implicitly casted to int. So, you have to do that explicitly.

But += is coded in such a way that it does type casting. i=(int)(i+m)

Try it.

ws.Range("A1:F2").Merge();

Using HTML 5,Just make the input email like :

<input type="email"/>

When the user hovers over the input box, they will a tooltip instructing them to enter a valid email. However, Bootstrap forms have a much better Tooltip message to tell the user to enter an email address and it pops up the moment the value entered does not match a valid email.

You can do it with Array.prototype.filter(),

var data = { records : [{ "empid": 1, "fname": "X", "lname": "Y" }, { "empid": 2, "fname": "A", "lname": "Y" }, { "empid": 3, "fname": "B", "lname": "Y" }, { "empid": 4, "fname": "C", "lname": "Y" }, { "empid": 5, "fname": "C", "lname": "Y" }] }
var empIds = [1,4,5]
var filteredArray = data.records.filter(function(itm){
  return empIds.indexOf(itm.empid) > -1;
});

filteredArray = { records : filteredArray };

If? the ?callBack? returns a ?true? value, then the ?itm? passed to that particular callBack will be filtered out. You can read more about it here.??????

foreach($array as $item=>$values){
     echo $values->filepath;
    }

Please use regex to remove anything before |

example

dsfdf | fdfsfsf
dsdss|gfghhghg
dsdsds |dfdsfsds

Use find and replace in notepad++

find: .+(\|) replace: \1

output

| fdfsfsf
|gfghhghg
|dfdsfsds

Given your example, you need to add the following import in your main.main class:

import second.second;

Some bonus advice, make sure you titlecase your class names as that is a Java standard. So your example Main class will have the structure:

package main;  //lowercase package names
public class Main //titlecase class names
{
    //Main class content
}

Have a look at the following apache commons function:

org.apache.commons.io.FileUtils.readFileToByteArray(File)

You can pass the inline handler the this keyword, obtaining the element which fired the event.

like,

onclick="confirmSubmit(this);"

Since ArrayList takes to much memory when I need array of primitive types, I prefer using IntStream.builder() for creating int array (You can also use LongStream and DoubleStream builders).

Example:

Builder builder = IntStream.builder();
int arraySize = new Random().nextInt();
for(int i = 0; i<arraySize; i++ ) {
    builder.add(i);
}
int[] array = builder.build().toArray();

Note: available since Java 8.

When TOP is used with INSERT, UPDATE, MERGE, or DELETE, the referenced rows are not arranged in any order and the ORDER BY clause can not be directly specified in these statements. If you need to use TOP to insert, delete, or modify rows in a meaningful chronological order, you must use TOP together with an ORDER BY clause that is specified in a subselect statement.

TOP cannot be used in an UPDATE and DELETE statements on partitioned views.

TOP cannot be combined with OFFSET and FETCH in the same query expression (in the same query scope). For more information, see http://technet.microsoft.com/en-us/library/ms189463.aspx

The trick is to add both max-height: 100%; and max-width: 100%; to .container img. Example CSS:

.container {
  width: 300px;
  border: dashed blue 1px;
}

.container img {
  max-height: 100%;
  max-width: 100%;
}

In this way, you can vary the specified width of .container in whatever way you want (200px or 10% for example), and the image will be no larger than its natural dimensions. (You could specify pixels instead of 100% if you didn't want to rely on the natural size of the image.)

Here's the whole fiddle: http://jsfiddle.net/KatieK/Su28P/1/

You can do it more simply, guaranteeing that your .gitconfig is left in a meaningful state:

Using Git version v1.8.0 and above

git push -u hub master when pushing, or:
git branch -u hub/master

OR

(This will set the remote for the currently checked-out branch to hub/master)
git branch --set-upstream-to hub/master

OR

(This will set the remote for the branch named branch_name to hub/master)
git branch branch_name --set-upstream-to hub/master

If you're using v1.7.x or earlier

you must use --set-upstream:
git branch --set-upstream master hub/master

The method you are looking for is not specific to Android, but to Java in general. You're looking for the MessageDigest (import java.security.MessageDigest).

An implementation of a sha512(String s) method can be seen here, and the change for a SHA-1 hash would be changing line 71 to:

MessageDigest md = MessageDigest.getInstance("SHA-1");

use git bundle, or clone

copying the git directory is not a good solution because it is not atomic. If you have a large repository that takes a long time to copy and someone pushes to your repository, it will affect your back up. Cloning or making a bundle will not have this problem.

There are at least two ways to do it:

The first is the one others have mentioned here before me. I think it's the simplest and preferred way. You just to keep track of

• cn: counter of how many frames you've rendered
• time_start: the time since you've started counting
• time_now: the current time

Calculating the fps in this case is as simple as evaluating this formula:

• FPS = cn / (time_now - time_start).

Then there is the uber cool way you might like to use some day:

Let's say you have 'i' frames to consider. I'll use this notation: f[0], f[1],..., f[i-1] to describe how long it took to render frame 0, frame 1, ..., frame (i-1) respectively.

Example where i = 3

|f[0]      |f[1]         |f[2]   |
+----------+-------------+-------+------> time

Then, mathematical definition of fps after i frames would be

(1) fps[i]   = i     / (f[0] + ... + f[i-1])

And the same formula but only considering i-1 frames.

(2) fps[i-1] = (i-1) / (f[0] + ... + f[i-2]) 

Now the trick here is to modify the right side of formula (1) in such a way that it will contain the right side of formula (2) and substitute it for it's left side.

Like so (you should see it more clearly if you write it on a paper):

fps[i] = i / (f[0] + ... + f[i-1])
       = i / ((f[0] + ... + f[i-2]) + f[i-1])
       = (i/(i-1)) / ((f[0] + ... + f[i-2])/(i-1) + f[i-1]/(i-1))
       = (i/(i-1)) / (1/fps[i-1] + f[i-1]/(i-1))
       = ...
       = (i*fps[i-1]) / (f[i-1] * fps[i-1] + i - 1)

So according to this formula (my math deriving skill are a bit rusty though), to calculate the new fps you need to know the fps from the previous frame, the duration it took to render the last frame and the number of frames you've rendered.

Both the solutions above work, however, Antonio's does the job with less code, here is how it helped me resolve data from my database, from several different child refs and then pushing them all into an array and resolving it in a promise after all is done:

Promise.all(PacksList.map((pack)=>{
    return fireBaseRef.child(pack.folderPath).once('value',(snap)=>{
        snap.forEach( childSnap => {
            const file = childSnap.val()
            file.id = childSnap.key;
            allItems.push( file )
        })
    })
})).then(()=>store.dispatch( actions.allMockupItems(allItems)))

You can use "\n" in Paragraph

document.add(new Paragraph("\n\n"));

If you want a breakdown of how many files are in each dir under your current dir:

for i in */ .*/ ; do 
    echo -n $i": " ; 
    (find "$i" -type f | wc -l) ; 
done

That can go all on one line, of course. The parenthesis clarify whose output wc -l is supposed to be watching (find $i -type f in this case).

best way to Round off number to decimal places is that

a=parseFloat(Math.round(numbertobeRound*10^decimalplaces)/10^decimalplaces);

for Example ;

numbertobeRound=58.8965896589;

if you want 58.90

decimalplaces is 2

a=parseFloat(Math.round(58.8965896589*10^2)/10^2);

You have to load the db library first. In autoload.php add :

$autoload['libraries'] = array('database');

Also, try renaming User model class for "User_model".

If you are running against IIS rather than the VS webdev server, ensure that Index.aspx is one of your default files and that directory browsing is turned off.

Many guys posted onKeyDown() event which is not working at all i.e. you can not delete once you reach the limit. So instead of onKeyDown() use onKeyPress() and it works perfectly fine.

Below is working code:

User will not be allowed to enter more than 4 digits_x000D_
<br>_x000D_
<input type="number" pattern="/^-?\d+\.?\d*$/" onKeyPress="if(this.value.length==4) return false;" />

The problem is that PHP mail() function has a very limited functionality. There are several ways to send mail from PHP.

1. mail() uses SMTP server on your system. There are at least two servers you can use on Windows: hMailServer and xmail. I spent several hours configuring and getting them up. First one is simpler in my opinion. Right now, hMailServer is working on Windows 7 x64.
2. mail() uses SMTP server on remote or virtual machine with Linux. Of course, real mail service like Gmail doesn't allow direct connection without any credentials or keys. You can set up virtual machine or use one located in your LAN. Most linux distros have mail server out of the box. Configure it and have fun. I use default exim4 on Debian 7 that listens its LAN interface.
3. Mailing libraries use direct connections. Libs are easier to set up. I used SwiftMailer and it perfectly sends mail from Gmail account. I think that PHPMailer is pretty good too.

No matter what choice is your, I recommend you use some abstraction layer. You can use PHP library on your development machine running Windows and simply mail() function on production machine with Linux. Abstraction layer allows you to interchange mail drivers depending on system which your application is running on. Create abstract MyMailer class or interface with abstract send() method. Inherit two classes MyPhpMailer and MySwiftMailer. Implement send() method in appropriate ways.

SELECT o.*
FROM `DocumentStatusLogs` o                   
  LEFT JOIN `DocumentStatusLogs` b                   
  ON o.DocumentID = b.DocumentID AND o.DateCreated < b.DateCreated
 WHERE b.DocumentID is NULL ;

If you want to return only recent document order by DateCreated, it will return only top 1 document by DocumentID

Try this:

printf '\n%s\n' 'I want this on a new line!'

That allows you to separate the formatting from the actual text. You can use multiple placeholders and multiple arguments.

quantity=38; price=142.15; description='advanced widget'
$ printf '%8d%10.2f  %s\n' "$quantity" "$price" "$description"
      38    142.15  advanced widget

No one touched on it yet but it is something that every PHP developer should be able to speak at length about: Why is register_globals bad?

Since C++11, you can also use a lambda expression instead of defining a comparator struct:

auto comp = [](const string& a, const string& b) { return a.length() < b.length(); };
map<string, string, decltype(comp)> my_map(comp);

my_map["1"]      = "a";
my_map["three"]  = "b";
my_map["two"]    = "c";
my_map["fouuur"] = "d";

for(auto const &kv : my_map)
    cout << kv.first << endl;

Output:

1
two
three
fouuur

I'd like to repeat the final note of Georg's answer: When comparing by length you can only have one string of each length in the map as a key.

Code on Ideone

PHP has a built in function called json_decode(). Just pass the JSON string into this function and it will convert it to the PHP equivalent string, array or object.

In order to pass it as a string from Javascript, you can convert it to JSON using

JSON.stringify(object);

or a library such as Prototype

Actually, you could still use the round function:

>>> print round(1123.456789, -1)
1120.0

This would round to the closest multiple of 10. To 100 would be -2 as the second argument and so forth.

There is a simple solution to this for someone new to this:

Edit the configuration file in your local .git directory (config). Change git: to https: below.

[remote "origin"]
    url = https://github.com/your_username/your_repo

It says it all IsNullOrEmpty() does not include white spacing while IsNullOrWhiteSpace() does!

IsNullOrEmpty() If string is:
-Null
-Empty

IsNullOrWhiteSpace() If string is:
-Null
-Empty
-Contains White Spaces Only

System.String (with capital S) is already nullable, you do not need to declare it as such.

(string? myStr) is wrong.

LINQ provides Last():

csharp> int[] nums = {1,2,3,4,5};
csharp> nums.Last();              
5

This is handy when you don't want to make a variable unnecessarily.

string lastName = "Abraham Lincoln".Split().Last();

The default timeout is defined by default_socket_timeout ini-setting, which is 60 seconds. You can also change it on the fly:

ini_set('default_socket_timeout', 900); // 900 Seconds = 15 Minutes

Another way to set a timeout, would be to use stream_context_create to set the timeout as HTTP context options of the HTTP stream wrapper in use:

$ctx = stream_context_create(array('http'=>
    array(
        'timeout' => 1200,  //1200 Seconds is 20 Minutes
    )
));

echo file_get_contents('http://example.com/', false, $ctx);

I just faced the same issue with Fedora26 where many tools such as dnf were broken due to bad magic number for six. For an unknown reason i've got a file /usr/bin/six.pyc, with the unexpected magic number. Deleting this file fix the problem

Firstly, I am not an authority on WebClient vs. HttpClient, specifically. Secondly, from your comments above, it seems to suggest that WebClient is Sync ONLY whereas HttpClient is both.

I did a quick performance test to find how WebClient (Sync calls), HttpClient (Sync and Async) perform. and here are the results.

I see that as a huge difference when thinking for future, i.e. long running processes, responsive GUI, etc. (add to the benefit you suggest by framework 4.5 - which in my actual experience is hugely faster on IIS)

@AZ13's answer is good, but as per the Android design guidelines, the ActionBar should be at least 48dp high.

I think you want to cast your dt to a date and fix the format of your date literal:

SELECT *
FROM table
WHERE dt::date = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

Or the standard version:

SELECT *
FROM table
WHERE CAST(dt AS DATE) = '2011-01-01' -- This should be ISO-8601 format, YYYY-MM-DD

The extract function doesn't understand "date" and it returns a number.

Your makefile should ideally be named makefile, not make. Note that you can call your makefile anything you like, but as you found, you then need the -f option with make to specify the name of the makefile. Using the default name of makefile just makes life easier.

I know this is an old question, but I recently ran into this same issue. It ended up being a Proguard problem (when I set minifyEnabled to false it stopped happening.)

To stop it, with proguard enabled, I added the following to my proguard rules file, thanks to a solution I found elsewhere (after discovering that the problem was proguard)

-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

Not sure if they're necessary, but I also added these lines:

-keep class com.google.** { *; }
-keep interface com.google.** { *; }

You should use sb.delete(0, sb.length()) or sb.setLength(0) and NOT create a new StringBuilder().

See this related post for performance: Is it better to reuse a StringBuilder in a loop?

Being as it is a setting that is stored per-user, the session is an appropriate place to store the informtion.

I would change your controller to take the culture string as a parameter, rather than having a different action method for each potential culture. Adding a link to the page is easy, and you shouldn't need to write the same code repeatedly any time a new culture is required.

public class CultureController : Controller    
{
        public ActionResult SetCulture(string culture)
        {
            HttpContext.Session["culture"] = culture
            return RedirectToAction("Index", "Home");
        }        
}

<li><%= Html.ActionLink("French", "SetCulture", new {controller = "Culture", culture = "fr-FR"})%></li>
<li><%= Html.ActionLink("Spanish", "SetCulture", new {controller = "Culture", culture = "es-ES"})%></li>

There is no exists for a SCALAR in Perl, anyway. The Perl way is

defined( $x ) 

and the equivalent Java is

anInteger != null

Those are the equivalents.

exists $hash{key}

Is like the Java

From your example, I think you're looking for

if ( startIn != null ) { ...

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

I hope will do the same for you!

You can duplicate a table without data by running:

CREATE TABLE x LIKE y;

(See the MySQL CREATE TABLE Docs)

You could write a script that takes the output from SHOW TABLES from one database and copies the schema to another. You should be able to reference schema+table names like:

CREATE TABLE x LIKE other_db.y;

As far as the data goes, you can also do it in MySQL, but it's not necessarily fast. After you've created the references, you can run the following to copy the data:

INSERT INTO x SELECT * FROM other_db.y;

If you're using MyISAM, you're better off to copy the table files; it'll be much faster. You should be able to do the same if you're using INNODB with per table table spaces.

If you do end up doing an INSERT INTO SELECT, be sure to temporarily turn off indexes with ALTER TABLE x DISABLE KEYS!

EDIT Maatkit also has some scripts that may be helpful for syncing data. It may not be faster, but you could probably run their syncing scripts on live data without much locking.

In that case you don't want to insert size and color inside an array, but into an object

var options = { 
    'size': size,
    'color': color
  };

Afterwards you can access the sets of keys by

var keys = Object.keys( options );

For compatibility with IE 8+ use:

-ms-word-break: break-all;
     word-break: break-all;

     /* Non standard for webkit */
     word-break: break-word;

-webkit-hyphens: auto;
   -moz-hyphens: auto;
        hyphens: auto;

See it here http://css-tricks.com/snippets/css/prevent-long-urls-from-breaking-out-of-container/

All I had to do was apply this to the style of the div container with a set width.

from official doc version 4

const express = require('express')
const app = express()
app.use(express.json());
app.use(express.urlencoded({ extended: true })) 

app.post('/push/send', (request, response) => {
  console.log(request.body)
})

Another thought here is to extend testing to "internal" classes/methods, giving more of a white-box sense of this testing. You can use InternalsVisibleToAttribute on the assembly to expose these to separate unit testing modules.

In combination with sealed class you can approach such encapsulation that test method are visible only from unittest assembly your methods. Consider that protected method in sealed class is de facto private.

[assembly: InternalsVisibleTo("MyCode.UnitTests")]
namespace MyCode.MyWatch
{
    #pragma warning disable CS0628 //invalid because of InternalsVisibleTo
    public sealed class MyWatch
    {
        Func<DateTime> _getNow = delegate () { return DateTime.Now; };


       //construktor for testing purposes where you "can change DateTime.Now"
       internal protected MyWatch(Func<DateTime> getNow)
       {
           _getNow = getNow;
       }

       public MyWatch()
       {            
       }
   }
}

And unit test:

namespace MyCode.UnitTests
{

[TestMethod]
public void TestminuteChanged()
{
    //watch for traviling in time
    DateTime baseTime = DateTime.Now;
    DateTime nowforTesting = baseTime;
    Func<DateTime> _getNowForTesting = delegate () { return nowforTesting; };

    MyWatch myWatch= new MyWatch(_getNowForTesting );
    nowforTesting = baseTime.AddMinute(1); //skip minute
    //TODO check myWatch
}

[TestMethod]
public void TestStabilityOnFebruary29()
{
    Func<DateTime> _getNowForTesting = delegate () { return new DateTime(2024, 2, 29); };
    MyWatch myWatch= new MyWatch(_getNowForTesting );
    //component does not crash in overlap year
}
}

Update alpha 47

As of alpha 47 the below answer (for alpha46 and below) is not longer required. Now the Http module handles automatically the errores returned. So now is as easy as follows

http
  .get('Some Url')
  .map(res => res.json())
  .subscribe(
    (data) => this.data = data,
    (err) => this.error = err); // Reach here if fails

Alpha 46 and below

You can handle the response in the map(...), before the subscribe.

http
  .get('Some Url')
  .map(res => {
    // If request fails, throw an Error that will be caught
    if(res.status < 200 || res.status >= 300) {
      throw new Error('This request has failed ' + res.status);
    } 
    // If everything went fine, return the response
    else {
      return res.json();
    }
  })
  .subscribe(
    (data) => this.data = data, // Reach here if res.status >= 200 && <= 299
    (err) => this.error = err); // Reach here if fails

Here's a plnkr with a simple example.

Note that in the next release this won't be necessary because all status codes below 200 and above 299 will throw an error automatically, so you won't have to check them by yourself. Check this commit for more info.

Try

let refresch = ()=>  document.body.style= 'background: #'
  +Math.random().toString(16).slice(-6);

let intId = setInterval(refresch, 1000);

let stop = ()=> clearInterval(intId);

body {transition: 1s}

<button onclick="stop()">Stop</button>

For a time difference, note that the calendar starts at 01.01.1970, 01:00, not at 00:00. If you're using java.util.Date and java.text.SimpleDateFormat, you will have to compensate for 1 hour:

long start = System.currentTimeMillis();
long end = start + (1*3600 + 23*60 + 45) * 1000 + 678; // 1 h 23 min 45.678 s
Date timeDiff = new Date(end - start - 3600000); // compensate for 1h in millis
SimpleDateFormat timeFormat = new SimpleDateFormat("H:mm:ss.SSS");
System.out.println("Duration: " + timeFormat.format(timeDiff));

This will print:

Duration: 1:23:45.678

That flag is dangerous!! Leaves your file system open for access. Documents originating from anywhere, local or web, should not, by default, have any access to local file:/// resources.

Much better solution is to run a little http server locally.

--- For Windows ---

The easiest is to install http-server globally using node's package manager:

npm install -g http-server

Then simply run http-server in any of your project directories:

Eg. d:\my_project> http-server

Starting up http-server, serving ./
Available on:
 http:169.254.116.232:8080
 http:192.168.88.1:8080
 http:192.168.0.7:8080
 http:127.0.0.1:8080
Hit CTRL-C to stop the server

Or as prusswan suggested, you can also install Python under windows, and follow the instructions below.

--- For Linux ---

Since Python is usually available in most linux distributions, just run python -m SimpleHTTPServer in your project directory, and you can load your page on http://localhost:8000

In Python 3 the SimpleHTTPServer module has been merged into http.server, so the new command is python3 -m http.server.

Easy, and no security risk of accidentally leaving your browser open vulnerable.

If you need an algorithm, try this: Convert the color from RGB space to HSV space (Hue, Saturation, Value). If your UI framework can't do it, check this article: http://en.wikipedia.org/wiki/HSL_and_HSV#Conversion_from_RGB_to_HSL_or_HSV

Hue is in [0,360). To find the "opposite" color (think colorwheel), just add 180 degrees:

h = (h + 180) % 360;

For saturation and value, invert them:

l = 1.0 - l;
v = 1.0 - v;

Convert back to RGB. This should always give you a high contrast even though most combinations will look ugly.

If you want to avoid the "ugly" part, build a table with several "good" combinations, find the one with the least difference

def q(x):
    return x*x
def diff(col1, col2):
    return math.sqrt(q(col1.r-col2.r) + q(col1.g-col2.g) + q(col1.b-col2.b))

and use that.

moment.js is great but sometimes you don't want to pull a large number of dependencies for simple things.

The following works as well:

var tzoffset = (new Date()).getTimezoneOffset() * 60000; //offset in milliseconds
var localISOTime = (new Date(Date.now() - tzoffset)).toISOString().slice(0, -1);
// => '2015-01-26T06:40:36.181'

The slice(0, -1) gets rid of the trailing Z which represents Zulu timezone and can be replaced by your own.

I don't know what's wrong with yours but one thing for sure is you need to call AES_set_decrypt_key() before decrypting the message. Also don't try to print out as %s because the encrypted message isn't composed by ascii characters anymore.. For example:

static const unsigned char key[] = {
    0x00, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77,
    0x88, 0x99, 0xaa, 0xbb, 0xcc, 0xdd, 0xee, 0xff,
    0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
    0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f
};

int main()
{
    unsigned char text[]="hello world!";
    unsigned char enc_out[80];
    unsigned char dec_out[80];

    AES_KEY enc_key, dec_key;

    AES_set_encrypt_key(key, 128, &enc_key);
    AES_encrypt(text, enc_out, &enc_key);      

    AES_set_decrypt_key(key,128,&dec_key);
    AES_decrypt(enc_out, dec_out, &dec_key);

    int i;

    printf("original:\t");
    for(i=0;*(text+i)!=0x00;i++)
        printf("%X ",*(text+i));
    printf("\nencrypted:\t");
    for(i=0;*(enc_out+i)!=0x00;i++)
        printf("%X ",*(enc_out+i));
    printf("\ndecrypted:\t");
    for(i=0;*(dec_out+i)!=0x00;i++)
        printf("%X ",*(dec_out+i));
    printf("\n");

    return 0;
} 

U1: your key is 192 bit isn't it...

Use this to change the hint color. -

editText.setHintTextColor(getResources().getColor(R.color.white));

Solution for your problem -

editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence arg0, int arg1, int arg2,int arg3){
        //do something
    }

    @Override
    public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
        //do something
    }

    @Override
    public void afterTextChanged(Editable arg0) {
        if(arg0.toString().length() <= 0) //check if length is equal to zero
            tv.setHintTextColor(getResources().getColor(R.color.white));
    }
});

Another way to find out where a class is loaded from (without manipulating the source) is to start the Java VM with the option: -verbose:class

Guys remember that you can use the try catch end event

Dim Green as integer

Try
    Green = InputBox("Please enter a value for green")
    Catch ex as Exception
        MsgBox("Green must be a valid integer!")
End Try

A simple solution would be to kill the focus, just create your own class:

public class ViewOnlyTextBox : System.Windows.Forms.TextBox {
    // constants for the message sending
    const int WM_SETFOCUS = 0x0007;
    const int WM_KILLFOCUS = 0x0008;

    protected override void WndProc(ref Message m) {
        if(m.Msg == WM_SETFOCUS) m.Msg = WM_KILLFOCUS;

        base.WndProc (ref m);
    }
}

It sets the distance of the inset between the content view and the enclosing scroll view.

Obj-C

aScrollView.contentInset = UIEdgeInsetsMake(0, 0, 0, 7.0);

Swift 5.0

aScrollView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 7.0)

Here's a good iOS Reference Library article on scroll views that has an informative screenshot (fig 1-3) - I'll replicate it via text here:

  _|?_cW_?_|_?_
   |       | 
---------------
   |content| ?
 ? |content| contentInset.top
cH |content|
 ? |content| contentInset.bottom
   |content| ?
---------------
  _|_______|___ 
             ?


   (cH = contentSize.height; cW = contentSize.width)

The scroll view encloses the content view plus whatever padding is provided by the specified content insets.

DateTime currentDateTime = DateTime.Now;
int week = (int) currentDateTime.DayOfWeek;

Easier solution:

SELECT numtodsinterval(date1-date2,'day') time_difference from dates;

For timestamps:

SELECT (extract(DAY FROM time2-time1)*24*60*60)+ 
(extract(HOUR FROM time2-time1)*60*60)+
(extract(MINUTE FROM time2-time1)*60)+
extract(SECOND FROM time2-time1)
into diff FROM dual;

RETURN diff;

It will help you a lot Basic Git Commands

template<class...>struct types{using type=types;};
template<class T>struct tag{using type=T;};
template<class Tag>using type_t=typename Tag::type;

the above helpers let you work with types as values.

class A {
  template<class T>
  A( tag<T> );
};

the tag<T> type is a variable with no state besides the type it caries. You can use this to pass a pure-type value into a template function and have the type be deduced by the template function:

auto a = A(tag<int>{});

You can pass in more than one type:

class A {
  template<class T, class U, class V>
  A( types<T,U,V> );
};
auto a = A(types<int,double,std::string>{});

A facade should not be described as a class which contains a lot of other classes. It is in fact a interface to this classes and should make the usage of the classes easier otherwise the facade class is useless.

// logout

if(isset($_GET['logout'])) {
    session_destroy();
    unset($_SESSION['username']);
    header('location:login.php');
}

?>

your string is NOT a valid json to start with.

a valid json will be,

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

if you do a json_decode, it will yield,

stdClass Object
(
    [area] => Array
        (
            [0] => stdClass Object
                (
                    [area] => kothrud
                )

            [1] => stdClass Object
                (
                    [area] => katraj
                )

        )

)

Update: to use

$string = '

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

';
            $area = json_decode($string, true);

            foreach($area['area'] as $i => $v)
            {
                echo $v['area'].'<br/>';
            }

Output:

kothrud
katraj

The current, ie. 2017 way to do this is:

heroku pg:reset DATABASE

https://devcenter.heroku.com/articles/heroku-postgresql#pg-reset

I know this thread is little old, but would like to add my 2 cents. We had the same "connection reset" error right after our one of the releases.

The root cause was, our apache server was brought down for deployment. All our third party traffic goes thru apache and we were getting connection reset error because of it being down.

In this case, myvar should be a boolean value. If this variable is true, it will show the div, if it's false.. It will hide.

Check this out.

Here is a solution that removes all lines that are either blank or contain only space characters:

grep -v '^[[:space:]]*$' foo.txt

The reason you are getting the the IOException is because you are not catching the IOException of your countLines method. You'll want to do something like this:

public static void main(String[] args) {
  int lines = 0;  

  // TODO - Need to get the filename to populate sFileName.  Could
  // come from the command line arguments.

   try {
       lines = LineCounter.countLines(sFileName);
    }
    catch(IOException ex){
        System.out.println (ex.toString());
        System.out.println("Could not find file " + sFileName);
    }

   if(lines > 0) {
     // Do rest of program.
   }
}

If you need that each div will have its own toggle and don't want clicks to affect other divs, do this:

Here's what I did to solve this...

<div [ngClass]="{'teaser': !teaser_1 }" (click)="teaser_1=!teaser_1">
...content...
</div>

<div [ngClass]="{'teaser': !teaser_2 }" (click)="teaser_2=!teaser_2">
...content...
</div>

<div [ngClass]="{'teaser': !teaser_3 }" (click)="teaser_3=!teaser_3">
...content...
</div>

it requires custom numbering which sucks, but it works.

Hope this Code you are looking for HTML:

            <div class="showmore">
                <div class="shorten_txt">
                    <h4> #@item.Title</h4>
                    <p>Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text Your Text </p>
                </div>
            </div>

SCRIPT:

    var showChar = 100;
    var ellipsestext = "[...]";
    $('.showmore').each(function () {
        $(this).find('.shorten_txt p').addClass('more_p').hide();
        $(this).find('.shorten_txt p:first').removeClass('more_p').show();
        $(this).find('.shorten_txt ul').addClass('more_p').hide();
        //you can do this above with every other element
        var teaser = $(this).find('.shorten_txt p:first').html();
        var con_length = parseInt(teaser.length);
        var c = teaser.substr(0, showChar);
        var h = teaser.substr(showChar, con_length - showChar);
        var html = '<span class="teaser_txt">' + c + '<span class="moreelipses">' + ellipsestext +
        '</span></span><span class="morecontent_txt">' + h

        if (con_length > showChar) {
            $(this).find(".shorten_txt p:first").html(html);
            $(this).find(".shorten_txt p:first span.morecontent_txt").toggle();
        }
    });
    $(".showmore").click(function () {
        if ($(this).hasClass("less")) {
            $(this).removeClass("less");
        } else {
            $(this).addClass("less");
        }
        $(this).find('.shorten_txt p:first span.moreelipses').toggle();

        $(this).find('.shorten_txt .more_p').toggle();
        return false;
    });

Use the vector constructor that takes two iterators, note that pointers are valid iterators, and use the implicit conversion from arrays to pointers:

int x[3] = {1, 2, 3};
std::vector<int> v(x, x + sizeof x / sizeof x[0]);
test(v);

or

test(std::vector<int>(x, x + sizeof x / sizeof x[0]));

where sizeof x / sizeof x[0] is obviously 3 in this context; it's the generic way of getting the number of elements in an array. Note that x + sizeof x / sizeof x[0] points one element beyond the last element.

if permission issue and you have ssh access in root folder

find . -type d -exec chmod 755 {} \;
find . -type f -exec chmod 644 {} \;

will resolve your error

You just need to make sure that the containers you want to talk to each other are on the same network. Networks are a first-class docker construct, and not specific to compose.

# front/docker-compose.yml
version: '2'
services:
  front:
    ...
    networks:
      - some-net
networks:
  some-net:
    driver: bridge

...

# api/docker-compose.yml
version: '2'
services:
  api:
    ...
    networks:
      - front_some-net
networks:
  front_some-net:
    external: true

Note: Your app’s network is given a name based on the “project name”, which is based on the name of the directory it lives in, in this case a prefix front_ was added

They can then talk to each other using the service name. From front you can do ping api and vice versa.

Using following simple formula is much faster

=LOOKUP(2,1/(A:A<>""),A:A)

For Excel 2003:

=LOOKUP(2,1/(A1:A65535<>""),A1:A65535)

It gives you following advantages:

• it's not array formula
• it's not volatile formula

Explanation:

• (A:A<>"") returns array {TRUE,TRUE,..,FALSE,..}
• 1/(A:A<>"") modifies this array to {1,1,..,#DIV/0!,..}.
• Since LOOKUP expects sorted array in ascending order, and taking into account that if the LOOKUP function can not find an exact match, it chooses the largest value in the lookup_range (in our case {1,1,..,#DIV/0!,..}) that is less than or equal to the value (in our case 2), formula finds last 1 in array and returns corresponding value from result_range (third parameter - A:A).

Also little note - above formula doesn't take into account cells with errors (you can see it only if last non empty cell has error). If you want to take them into account, use:

=LOOKUP(2,1/(NOT(ISBLANK(A:A))),A:A)

image below shows the difference:

I had the same problem and ended up actually using border instead of padding.

In most cases a screen -RRx $username/ will suffice :)

If you still want to list all screens then put the following script in your path and call it screen or whatever you like:

#!/bin/bash
if [[ "$1" != "-ls-all" ]]; then
    exec /usr/bin/screen "$@"
else
    shopt -s nullglob
    screens=(/var/run/screen/S-*/*)
    if (( ${#screens[@]} == 0 )); then
        echo "no screen session found in /var/run/screen"
    else
        echo "${screens[@]#*S-}"
    fi
fi

It will behave exactly like screen except for showing all screen sessions, when giving the option -ls-all as first parameter.

In order to avoid OutOfMemory error for bigger files, I would solve the task by splitting a bitmap into several parts and merging their parts' bytes.

private byte[] getBitmapBytes(Bitmap bitmap)
{
    int chunkNumbers = 10;
    int bitmapSize = bitmap.getRowBytes() * bitmap.getHeight();
    byte[] imageBytes = new byte[bitmapSize];
    int rows, cols;
    int chunkHeight, chunkWidth;
    rows = cols = (int) Math.sqrt(chunkNumbers);
    chunkHeight = bitmap.getHeight() / rows;
    chunkWidth = bitmap.getWidth() / cols;

    int yCoord = 0;
    int bitmapsSizes = 0;

    for (int x = 0; x < rows; x++)
    {
        int xCoord = 0;
        for (int y = 0; y < cols; y++)
        {
            Bitmap bitmapChunk = Bitmap.createBitmap(bitmap, xCoord, yCoord, chunkWidth, chunkHeight);
            byte[] bitmapArray = getBytesFromBitmapChunk(bitmapChunk);
            System.arraycopy(bitmapArray, 0, imageBytes, bitmapsSizes, bitmapArray.length);
            bitmapsSizes = bitmapsSizes + bitmapArray.length;
            xCoord += chunkWidth;

            bitmapChunk.recycle();
            bitmapChunk = null;
        }
        yCoord += chunkHeight;
    }

    return imageBytes;
}


private byte[] getBytesFromBitmapChunk(Bitmap bitmap)
{
    int bitmapSize = bitmap.getRowBytes() * bitmap.getHeight();
    ByteBuffer byteBuffer = ByteBuffer.allocate(bitmapSize);
    bitmap.copyPixelsToBuffer(byteBuffer);
    byteBuffer.rewind();
    return byteBuffer.array();
}

In my case it was the security constraints defined in web.xml. Make sure they have the same roles you use in your tomcat-users.xml file.

For example, this is one of the out-of-the-box tags and will work with the standard tomcat-users.xml.

 <security-constraint>
    <web-resource-collection>
      <web-resource-name>HTML Manager interface (for humans)</web-resource-name>
      <url-pattern>/html/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
       <role-name>manager-gui</role-name>
    </auth-constraint>
  </security-constraint>

In my case an admin had used a different role-name which prevented me from accessing the manager.

1) JTable knows JCheckbox with built-in Boolean TableCellRenderers and TableCellEditor by default, then there is contraproductive declare something about that,

2) AbstractTableModel should be useful, where is in the JTable required to reduce/restrict/change nested and inherits methods by default implemented in the DefaultTableModel,

3) consider using DefaultTableModel, (if you are not sure about how to works) instead of AbstractTableModel,

could be generated from simple code:

import javax.swing.*;
import javax.swing.table.*;

public class TableCheckBox extends JFrame {

    private static final long serialVersionUID = 1L;
    private JTable table;

    public TableCheckBox() {
        Object[] columnNames = {"Type", "Company", "Shares", "Price", "Boolean"};
        Object[][] data = {
            {"Buy", "IBM", new Integer(1000), new Double(80.50), false},
            {"Sell", "MicroSoft", new Integer(2000), new Double(6.25), true},
            {"Sell", "Apple", new Integer(3000), new Double(7.35), true},
            {"Buy", "Nortel", new Integer(4000), new Double(20.00), false}
        };
        DefaultTableModel model = new DefaultTableModel(data, columnNames);
        table = new JTable(model) {

            private static final long serialVersionUID = 1L;

            /*@Override
            public Class getColumnClass(int column) {
            return getValueAt(0, column).getClass();
            }*/
            @Override
            public Class getColumnClass(int column) {
                switch (column) {
                    case 0:
                        return String.class;
                    case 1:
                        return String.class;
                    case 2:
                        return Integer.class;
                    case 3:
                        return Double.class;
                    default:
                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

            @Override
            public void run() {
                TableCheckBox frame = new TableCheckBox();
                frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
                frame.pack();
                frame.setLocation(150, 150);
                frame.setVisible(true);
            }
        });
    }
}

There is such possibility even if they are not Parent - Child relationship - and that's Flux. There is pretty good (for me personally) implementation for that called Alt.JS (with Alt-Container).

For example you can have Sidebar that is dependent on what is set in component Details. Component Sidebar is connected with SidebarActions and SidebarStore, while Details is DetailsActions and DetailsStore.

You could use then AltContainer like that

<AltContainer stores={{
                    SidebarStore: SidebarStore
                }}>
                    <Sidebar/>
</AltContainer>

{this.props.content}

Which would keep stores (well I could use "store" instead of "stores" prop). Now, {this.props.content} CAN BE Details depending on the route. Lets say that /Details redirect us to that view. Details would have for example a checkbox that would change Sidebar element from X to Y if it would be checked.

Technically there is no relationship between them and it would be hard to do without flux. BUT WITH THAT it is rather easy.

Now let's get to DetailsActions. We will create there

class SiteActions {
constructor() {
    this.generateActions(
        'setSiteComponentStore'
    );
}

setSiteComponent(value) {
    this.dispatch({value: value});
}
}

and DetailsStore

class SiteStore {
constructor() {
    this.siteComponents = {
        Prop: true
    };

    this.bindListeners({
        setSiteComponent: SidebarActions.COMPONENT_STATUS_CHANGED
    })
}

setSiteComponent(data) {
    this.siteComponents.Prop = data.value;
}
}

And now, this is the place where magic begin.

As You can see there is bindListener to SidebarActions.ComponentStatusChanged which will be used IF setSiteComponent will be used.

now in SidebarActions

    componentStatusChanged(value){
    this.dispatch({value: value});
}

We have such thing. It will dispatch that object on call. And it will be called if setSiteComponent in store will be used (that you can use in component for example during onChange on Button ot whatever)

Now in SidebarStore we will have

    constructor() {
    this.structures = [];

    this.bindListeners({
        componentStatusChanged: SidebarActions.COMPONENT_STATUS_CHANGED
    })
}

    componentStatusChanged(data) {
    this.waitFor(DetailsStore);

    _.findWhere(this.structures[0].elem, {title: 'Example'}).enabled = data.value;
}

Now here you can see, that it will wait for DetailsStore. What does it mean? more or less it means that this method need to wait for DetailsStoreto update before it can update itself.

tl;dr One Store is listening on methods in a store, and will trigger an action from component action, which will update its own store.

I hope it can help you somehow.

You can use BigDecimal

BigDecimal value = new BigDecimal("2.3");
value = value.setScale(0, RoundingMode.UP);
BigDecimal value1 = new BigDecimal("-2.3");
value1 = value1.setScale(0, RoundingMode.UP);
System.out.println(value + "n" + value1);

Refer: http://www.javabeat.net/precise-rounding-of-decimals-using-rounding-mode-enumeration/

C++14 lets you do static constexpr auto pi = acos(-1);

1. Local variables are located on the stack. Heap space is occupied by objects.

2. You can use the -Xmx option.

3. Basically heap space is used up everytime you allocate a new object with new and freed some time after the object is no longer referenced. So make sure that you don't keep references to objects that you no longer need.

Simply use the .closest() method: $(this).closest('.li').remove();
It starts with the current element and then climbs up the chain looking for a matching element and stops as soon as it found one.

.parent() only accesses the direct parent of the element, i.e. div.msg-modification which does not match .li. So it never reaches the element you are looking for.

Another solution besides .closest() (which checks the current element and then climbs up the chain) would be using .parents() - however, this would have the caveat that it does not stop as soon as it finds a matching element (and it doesn't check the current element but only parent elements). In your case it doesn't really matter but for what you are trying to do .closest() is the most appropriate method.

Another important thing:

NEVER use the same ID for more than one element. It's not allowed and causes very hard-to-debug problems. Remove the id="191" from the link and, if you need to access the ID in the click handler, use $(this).closest('.li').attr('id'). Actually it would be even cleaner if you used data-id="123" and then .data('id') instead of .attr('id') to access it (so your element ID does not need to resemble whatever ID the (database?) row has)

Please store your JSON file with the .js extension and make sure that your JSON should be in same directory.

It's a bit weird that I placed the start stop restart in a separate case but it should work

I suggest you to start with simple polynomial fit, scipy.optimize.curve_fit tries to fit a function f that you must know to a set of points.

This is a simple 3 degree polynomial fit using numpy.polyfit and poly1d, the first performs a least squares polynomial fit and the second calculates the new points:

import numpy as np
import matplotlib.pyplot as plt

points = np.array([(1, 1), (2, 4), (3, 1), (9, 3)])
# get x and y vectors
x = points[:,0]
y = points[:,1]

# calculate polynomial
z = np.polyfit(x, y, 3)
f = np.poly1d(z)

# calculate new x's and y's
x_new = np.linspace(x[0], x[-1], 50)
y_new = f(x_new)

plt.plot(x,y,'o', x_new, y_new)
plt.xlim([x[0]-1, x[-1] + 1 ])
plt.show()

Collections are a resource so /appointments is fine as the resource.

Collections also typically offer filters via the querystring which is essentially what users=id1,id2... is.

So,

/appointments?users=id1,id2 

is fine as a filtered RESTful resource.

Declare additional helper function like this:

template <class T, class I >
bool vectorContains(const vector<T>& v, I& t)
{
    bool found = (std::find(v.begin(), v.end(), t) != v.end());
    return found;
}

And use it like this:

void Project::AddPlatform(const char* platform)
{
    if (!vectorContains(platforms, platform))
        platforms.push_back(platform);
}

Snapshot of example can be found here:

https://github.com/tapika/cppscriptcore/blob/b7f3d62747494a52a440482e841ffb016a3fc56e/SolutionProjectModel/Project.cpp#L13

You can use // instead of single /. That converts to int directly.

You can initialize it just like any list:

public List<ContactNumber> ContactNumbers { get; set; }

public Human(int id)
{
    Id = id;
    ContactNumbers = new List<ContactNumber>();
}

public Human(int id, string address, string name) :this(id)
{
    Address = address;
    Name = name;
    // no need to initialize the list here since you're
    // already calling the single parameter constructor
}       

However, I would even go a step further and make the setter private since you often don't need to set the list, but just access/modify its contents:

public List<ContactNumber> ContactNumbers { get; private set; }

I had a slightly different problem. I worked with inputs in a modal and it drove me mad. No of the proposed solutions worked for me.

Until i found this issue: https://github.com/valor-software/ngx-bootstrap/issues/1597

This good guy gave me the hint that ngx-bootstrap modal has a focus configuration. If this configuration is not set to false, the modal will be focused after the animation and there is NO WAY to focus anything else.

Update:

To set this configuration, add the following attribute to the modal div:

[config]="{focus: false}"

Update 2:

To force the focus on the input field i wrote a directive and set the focus in every AfterViewChecked cycle as long as the input field has the class ng-untouched.

 ngAfterViewChecked() {
    // This dirty hack is needed to force focus on an input element of a modal.
    if (this.el.nativeElement.classList.contains('ng-untouched')) {
        this.renderer.invokeElementMethod(this.el.nativeElement, 'focus', []);
    }
}

Smallest code:

def contains(a,b):
    str(a)[1:-1].find(str(b)[1:-1])>=0

Remove all widths set using CSS and set white-space to nowrap like so:

.content-loader tr td {
    white-space: nowrap;
}

I would also remove the fixed width from the container (or add overflow-x: scroll to the container) if you want the fields to display in their entirety without it looking odd...

See more here: http://www.w3schools.com/cssref/pr_text_white-space.asp

Three basic rules:

1. Set pointer to NULL after free
2. Check for NULL before freeing.
3. Initialise pointer to NULL in the start.

Combination of these three works quite well.

Add below to pre-build event command line:

echo %date% %time% > "$(ProjectDir)\Resources\BuildDate.txt"

Add this file as resource, now you have 'BuildDate' string in your resources.

To create resources, see How to create and use resources in .NET.

What you are describing is actually what FontAwesome is doing already. They apply the FontAwesome font-family to the ::before pseudo element of any element that has a class that starts with "icon-".

[class^="icon-"]:before,
[class*=" icon-"]:before {
  font-family: FontAwesome;
  font-weight: normal;
  font-style: normal;
  display: inline-block;
  text-decoration: inherit;
}

Then they use the pseudo element ::before to place the icon in the element with the class. I just went to http://fortawesome.github.com/Font-Awesome/ and inspected the code to find this:

.icon-cut:before {
  content: "\f0c4";
}

So if you are looking to add the icon again, you could use the ::after element to achieve this. Or for your second part of your question, you could use the ::after pseudo element to insert the bullet character to look like a list item. Then use absolute positioning to place it to the left, or something similar.

i:after{ content: '\2022';}

I recommend using the awesome requests library:

import requests

url = 'http://maps.googleapis.com/maps/api/directions/json'

params = dict(
    origin='Chicago,IL',
    destination='Los+Angeles,CA',
    waypoints='Joplin,MO|Oklahoma+City,OK',
    sensor='false'
)

resp = requests.get(url=url, params=params)
data = resp.json() # Check the JSON Response Content documentation below

JSON Response Content: https://requests.readthedocs.io/en/master/user/quickstart/#json-response-content

$e=error_get_last();
if($e['message']!==''){
    // An error function
}

error_get_last(); - return the last error that occurred

I've implemented what I could gather from a few of these. This works in Windows, and since this is a community wiki, I figure I would share my code as well:

class Command(threading.Thread):
    def __init__(self, cmd, outFile, errFile, timeout):
        threading.Thread.__init__(self)
        self.cmd = cmd
        self.process = None
        self.outFile = outFile
        self.errFile = errFile
        self.timed_out = False
        self.timeout = timeout

    def run(self):
        self.process = subprocess.Popen(self.cmd, stdout = self.outFile, \
            stderr = self.errFile)

        while (self.process.poll() is None and self.timeout > 0):
            time.sleep(1)
            self.timeout -= 1

        if not self.timeout > 0:
            self.process.terminate()
            self.timed_out = True
        else:
            self.timed_out = False

Then from another class or file:

        outFile =  tempfile.SpooledTemporaryFile()
        errFile =   tempfile.SpooledTemporaryFile()

        executor = command.Command(c, outFile, errFile, timeout)
        executor.daemon = True
        executor.start()

        executor.join()
        if executor.timed_out:
            out = 'timed out'
        else:
            outFile.seek(0)
            errFile.seek(0)
            out = outFile.read()
            err = errFile.read()

        outFile.close()
        errFile.close()

This is a response I got from their Premium Services

Hello,

This is actually a issue with the way SSL validates names containing a period, '.', > character. We've documented this behavior here:

http://docs.amazonwebservices.com/AmazonS3/latest/dev/BucketRestrictions.html

The only straight-forward fix for this is to use a bucket name that does not contain that character. You might instead use a bucket named 'furniture-retailcatalog-us'. This would allow you use HTTPS with

https://furniture-retailcatalog-us.s3.amazonaws.com/

You could, of course, put a CNAME DNS record to make that more friendly. For example,

images-furniture.retailcatalog.us IN CNAME furniture-retailcatalog-us.s3.amazonaws.com.

Hope that helps. Let us know if you have any other questions.

Amazon Web Services

Unfortunately your "friendly" CNAME will cause host name mismatch when validating the certificate, therefore you cannot really use it for a secure connection. A big missing feature of S3 is accepting custom certificates for your domains.

UPDATE 10/2/2012

From @mpoisot:

The link Amazon provided no longer says anything about https. I poked around in the S3 docs and finally found a small note about it on the Virtual Hosting page: http://docs.amazonwebservices.com/AmazonS3/latest/dev/VirtualHosting.html

UPDATE 6/17/2013

From @Joseph Lust:

Just got it! Check it out and sign up for an invite: http://aws.amazon.com/cloudfront/custom-ssl-domains

The easiest way to do this is by using XML format.

1. Converting string to rows without table

QUERY

DECLARE @String varchar(100) = 'String1,String2,String3'
-- To change ',' to any other delimeter, just change ',' to your desired one
DECLARE @Delimiter CHAR = ','    

SELECT LTRIM(RTRIM(Split.a.value('.', 'VARCHAR(100)'))) 'Value' 
FROM  
(     
     SELECT CAST ('<M>' + REPLACE(@String, @Delimiter, '</M><M>') + '</M>' AS XML) AS Data            
) AS A 
CROSS APPLY Data.nodes ('/M') AS Split(a)

RESULT

 x---------x
 | Value   |
 x---------x
 | String1 |
 | String2 |
 | String3 |
 x---------x

2. Converting to rows from a table which have an ID for each CSV row

SOURCE TABLE

 x-----x--------------------------x
 | Id  |           Value          |
 x-----x--------------------------x
 |  1  |  String1,String2,String3 |
 |  2  |  String4,String5,String6 |     
 x-----x--------------------------x

QUERY

-- To change ',' to any other delimeter, just change ',' before '</M><M>' to your desired one
DECLARE @Delimiter CHAR = ','

SELECT ID,LTRIM(RTRIM(Split.a.value('.', 'VARCHAR(100)'))) 'Value' 
FROM  
(     
     SELECT ID,CAST ('<M>' + REPLACE(VALUE, @Delimiter, '</M><M>') + '</M>' AS XML) AS Data            
     FROM TABLENAME
) AS A 
CROSS APPLY Data.nodes ('/M') AS Split(a)

RESULT

 x-----x----------x
 | Id  |  Value   |
 x-----x----------x
 |  1  |  String1 |
 |  1  |  String2 |  
 |  1  |  String3 |
 |  2  |  String4 |  
 |  2  |  String5 |
 |  2  |  String6 |     
 x-----x----------x

Also download and unzip "Dependencies" into same folder where you put the wget.exe from

http://gnuwin32.sourceforge.net/packages/wget.htm

You will then have some lib*.dll files as well as wget.exe in the same folder and it should work fine.

(I also answered here https://superuser.com/a/873531/146668 which I originally found.)

In the button's XML set android:includeFontPadding="false"

Looping over arrays and objects is a pretty common task, and it's good that you're wanting to learn how to do it. Generally speaking you can do a foreach loop which cycles over each member, assigning it a new temporary name, and then lets you handle that particular member via that name:

foreach ($arr as $item) {
    echo $item->sm_id;
}

In this example each of our values in the $arr will be accessed in order as $item. So we can print our values directly off of that. We could also include the index if we wanted:

foreach ($arr as $index => $item) {
    echo "Item at index {$index} has sm_id value {$item->sm_id}";
}

You can of course use a loop, or you can insert them in a single statement, e.g.

Insert into db
(names,email,password) 
Values
('abc','def','mypassword')
,('ghi','jkl','mypassword2')
,('mno','pqr','mypassword3')

It really depends where you're getting your data from.

If you use a loop, wrapping it in a transaction will make it a bit faster.

UPDATE

What if i want to insert unique names?

If you want to insert unique names, then you need to generate data with unique names. One way to do this is to use Visual Studio to generate test data.

Why not use the built in events?

$('#checkbox').click(function(e){
    if(e.target.checked) {
     // code to run if checked
        console.log('Checked');

     } else {

     //code to run if unchecked
        console.log('Unchecked');
     }
});

you can stash the uncommitted changes using "git stash" then checkout to a new branch using "git checkout -b " then apply the stashed commits "git stash apply"

The character representation of a Space is simply ' '.

void foo (const char *s)
{
    unsigned char c;
    ...
    if (c == ' ')
        ...
}

But if you are really looking for all whitespace, then C has a function (actually it's often a macro) for that:

#include <ctype.h>
...

void foo (const char *s)
{
    char c;
    ...
    if (isspace(c))
        ...
}

You can read about isspace here

If you really want to catch all non-printing characters, the function to use is isprint from the same library. This deals with all of the characters below 0x20 (the ASCII code for a space) and above 0x7E (0x7f is the code for DEL, and everything above that is an extension).

In raw code this is equivalent to:

if (c < ' ' || c >= 0x7f)
    // Deal with non-printing characters.

The best solution I found so far is setting a footer element at the bottom of the page and then evaluate the difference of the offset of the footer and the element we need to expand. e.g.

The html file

<div id="contents"></div>
<div id="footer"></div>

The css file

#footer {
    position: fixed;
    bottom: 0;
    width: 100%;
}

The js file (using jquery)

var contents = $('#contents'); 
var footer = $('#footer');
contents.css('height', (footer.offset().top - contents.offset().top) + 'px');

You might also like to update the height of the contents element on each window resize, so...

$(window).on('resize', function() {
  contents.css('height', (footer.offset().top -contents.offset().top) + 'px');
});

Use sprintf :

sprintf('%08d', 1234567);

Alternatively you can also use str_pad:

str_pad($value, 8, '0', STR_PAD_LEFT);

in this code data is a two dimensional array of table data

let oTable = document.getElementById('datatable-id');
let data = [...oTable.rows].map(t => [...t.children].map(u => u.innerText))

If it ain't broke - fix it till it is...just kidding :)

But seriously BackgroundWorker is probably very similar to what you already have, had you started with it from the beginning maybe you would have saved some time - but at this point I don't see the need. Unless something isn't working, or you think your current code is hard to understand, then I would stick with what you have.

test -z returns true if the parameter is empty (see man sh or man test).

For me, It was a permission issue. I installed SQL server using a local user account and before joining my companies domain. Later on , I tried to restore a database using my domain account which doesn't have the permissions needed to restore SQL server databases. You need to fix the permission for your domain account and give it system admin permission on the SQL server instance you have.

If you have Xcode 4 Build Location setting set to "Place build products in derived data location (recommended), it should be located in ~/Library/Developer/Xcode/DerivedData. This directory will have your project in there as a directory, the project name will be appended with a bunch of generated letters so look carefully.

a) Can you explain to me the difference between int64_t and long (long int)? In my understanding, both are 64 bit integers. Is there any reason to choose one over the other?

The former is a signed integer type with exactly 64 bits. The latter is a signed integer type with at least 32 bits.

b) I tried to look up the definition of int64_t on the web, without much success. Is there an authoritative source I need to consult for such questions?

http://cppreference.com covers this here: http://en.cppreference.com/w/cpp/types/integer. The authoritative source, however, is the C++ standard (this particular bit can be found in §18.4 Integer types [cstdint]).

c) For code using int64_t to compile, I am including <iostream>, which doesn't make much sense to me. Are there other includes that provide a declaration of int64_t?

It is declared in <cstdint> or <cinttypes> (under namespace std), or in <stdint.h> or <inttypes.h> (in the global namespace).

This is because your $JAVA_HOME is not set. If you are using a Mac:

export JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home" in .bash_profile

It can be due to a number of reasons happening when configuring the listener. Best way is to log and see the actual error. You can do this by adding a logging.properties file to the root of your classpath with the following contents:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

I am looking for a solution to do this, but unzipping the files in javascript was not as clean as I liked. I decided to encapsulate the files into a single SVG file.

If you have the files stored on the server (I don't), you can simply set the href in the SVG.

In my case, I'll convert the files to base64 and embed them in the SVG.

Edit: The SVG worked very well. If you are only going to download the files, ZIP might be better. If you are going to display the files, then SVG seems superior.

If you don't mind using NumPy, then:

In [319]: real = np.array([1234.5678])

In [327]: integ, deci = int(np.floor(real)), np.asscalar(real % 1)

In [328]: integ, deci
Out[328]: (1234, 0.5678000000000338)

I just wanted to add a more effective and generic way to solve this kind of problems. The main idea is about working with sub queries.

do your group by and join the same table on the ID of the table.

your case is more specific since your productId is not unique so there is 2 ways to solve this.

I will begin by the more specific solution: Since your productId is not unique we will need an extra step which is to select DISCTINCT product ids after grouping and doing the sub query like following:

WITH CTE_TEST AS (SELECT productId, SUM(OrderQuantity) Total
                    FROM OrderDetails
                    GROUP BY productId)
SELECT DISTINCT(OrderDetails.ProductID), OrderDetails.ProductName, CTE_TEST.Total
FROM OrderDetails 
INNER JOIN CTE_TEST ON CTE_TEST.ProductID = OrderDetails.ProductID

this returns exactly what is expected

 ProductID     ProductName         Total
    1001          abc               12    
    1002          abc               23
    2002          xyz               8
    3004          ytp               15
    4001          aze               19

But there a cleaner way to do this. I guess that ProductId is a foreign key to products table and i guess that there should be and OrderId primary key (unique) in this table.

in this case there are few steps to do to include extra columns while grouping on only one. It will be the same solution as following

Let's take this t_Value table for example:

If i want to group by description and also display all columns.

All i have to do is:

1. create WITH CTE_Name subquery with your GroupBy column and COUNT condition
2. select all(or whatever you want to display) from value table and the total from the CTE
3. INNER JOIN with CTE on the ID(primary key or unique constraint) column

and that's it!

Here is the query

WITH CTE_TEST AS (SELECT Description, MAX(Id) specID, COUNT(Description) quantity 
                    FROM sch_dta.t_value
                    GROUP BY Description)
SELECT sch_dta.t_Value.*, CTE_TEST.quantity 
FROM sch_dta.t_Value 
INNER JOIN CTE_TEST ON CTE_TEST.specID = sch_dta.t_Value.Id

And here is the result:

I tried to require a development branch from a different repository and not the latest version and I had the same issue and non of the above worked for me :(

after a while I saw in the documentation that in cases of dev branch you need to require with a 'dev-' prefix to the version and the following worked perfectly.

composer require [vendorName]/[packageName]:dev-[gitBranchName]

First you create a UIImage from your image file, then create a UIImageView from that:

let imageName = "yourImage.png"
let image = UIImage(named: imageName)
let imageView = UIImageView(image: image!)

Finally you'll need to give imageView a frame and add it your view for it to be visible:

imageView.frame = CGRect(x: 0, y: 0, width: 100, height: 200)
view.addSubview(imageView)

You need to import time and then use time.time() method to know current time.

import time

start_time=time.time() #taking current time as starting time

#here your code

elapsed_time=time.time()-start_time #again taking current time - starting time 

cout << fixed << setprecision(2) << total;

setprecision specifies the minimum precision. So

cout << setprecision (2) << 1.2; 

will print 1.2

fixed says that there will be a fixed number of decimal digits after the decimal point

cout << setprecision (2) << fixed << 1.2;

will print 1.20

From SQL Server 2012 you can use a native pagination in order to have semplicity and best performance:

https://docs.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql?view=sql-server-ver15#using-offset-and-fetch-to-limit-the-rows-returned

Your query become:

SELECT * FROM Reflow  
WHERE ReflowProcessID = somenumber
ORDER BY ID DESC;
OFFSET 20 ROWS  
FETCH NEXT 20 ROWS ONLY;  

you can use lst.pop() or del lst[-1]

pop() removes and returns the item, in case you don't want have a return use del

I do my array looping and getting filled defaults accordingly in Swift 4/5

   for index in 0..<3
    {
        let isIndexValid = allObjects.indices.contains(index)
        var yourObject:Class = Class()
        if isIndexValid { yourObject = allObjects[index]}
        resultArray.append(yourObject)
    }

On top of your lastest jsfiddle, you just missed one thing:

#sidebar_wrap {
  width:40%;
  height:200px;
  background:green;
  float:right;
}
#sidebar {
  width:inherit;
  margin-top:10px;
  background-color:limegreen;
  position:fixed;
  max-width: 240px; /*This is you missed*/
}

But, how this will solve your problem? Simple, lets explain why is bigger than expect first.

Fixed element #sidebar will use window width size as base to get its own size, like every other fixed element, once in this element is defined width:inherit and #sidebar_wrap has 40% as value in width, then will calculate window.width * 40%, then when if your window width is bigger than your .container width, #sidebar will be bigger than #sidebar_wrap.

This is way, you must set a max-width in your #sidebar_wrap, to prevent to be bigger than #sidebar_wrap.

Check this jsfiddle that shows a working code and explain better how this works.

I found this to be the only reliable way (since Chrome & FF consider whitespaces and linebreaks as elements):

if($.trim($("selector").html())=='')

You didn't do what you're being asked to do.

What is asked:

I have to execute ../gradlew build

What you do

cd ..
gradlew build

That's not the same thing.

The first one will use the gradlew command found in the .. directory (mdeinum...), and look for the build file to execute in the current directory, which is (for example) chapter1-bookstore.

The second one will execute the gradlew command found in the current directory (mdeinum...), and look for the build file to execute in the current directory, which is mdeinum....

So the build file executed is not the same.

Probably svn import would be the best option around. Check out Getting Data into Your Repository (in Version Control with Subversion, For Subversion).

The svn import command is a quick way to copy an unversioned tree of files into a repository, creating intermediate directories as necessary. svn import doesn't require a working copy, and your files are immediately committed to the repository. You typically use this when you have an existing tree of files that you want to begin tracking in your Subversion repository. For example:

$ svn import /path/to/mytree \
             http://svn.example.com/svn/repo/some/project \
             -m "Initial import"
Adding         mytree/foo.c
Adding         mytree/bar.c
Adding         mytree/subdir
Adding         mytree/subdir/quux.h

Committed revision 1.
$

The previous example copied the contents of the local directory mytree into the directory some/project in the repository. Note that you didn't have to create that new directory first—svn import does that for you. Immediately after the commit, you can see your data in the repository:

$ svn list http://svn.example.com/svn/repo/some/project
bar.c
foo.c
subdir/
$

Note that after the import is finished, the original local directory is not converted into a working copy. To begin working on that data in a versioned fashion, you still need to create a fresh working copy of that tree.

Note: if you are on the same machine as the Subversion repository you can use the file:// specifier with a path rather than the https:// with a URL specifier.

One needs to install magrittr as follows

install.packages("magrittr")

Then, in one's script, don't forget to add on top

library(magrittr)

For the meaning of the operator %>% you might want to consider this question: What does %>% function mean in R?

Note that the same operator would also work with the library dplyr, as it imports from magrittr.

dplyr used to have a similar operator (%.%), which is now deprecated. Here we can read about the differences between %.% (deprecated operator from the library dplyr) and %>% (operator from magrittr, that is also available in dplyr)

For me, I forgot to add the default serial id.

private static final long serialVersionUID = 1L;

the OOP way without any strings as entities names Swift 3+, Xcode 10+

func batchDelete<T>(in context: NSManagedObjectContext, fetchRequest: NSFetchRequest<T>) throws {
    guard let request = fetchRequest as? NSFetchRequest<NSFetchRequestResult> else {
        throw ErrorService.defaultError
    }
    let batchDeleteRequest = NSBatchDeleteRequest(fetchRequest: request)
    do {
        try context.execute(batchDeleteRequest)
    } catch {
        throw error
    }
}

then just call in do/catch block

    let fetchRequest: NSFetchRequest<YourEntity> = YourEntity.fetchRequest()
    do {
        let data = try context.fetch(fetchRequest)
        if data.count > 0 {
            try self.batchDelete(in: context, fetchRequest: fetchRequest)
        }
    } catch {
        // throw error
    }

As of SQL Server 2012+, you can use FORMAT(value, format [, culture ])

Where the format param takes any valid standard format string or custom formatting string

Example:

SELECT FORMAT(GETDATE(), 'MM/dd/yyyy')

Further Reading:

• How to convert DateTime to VarChar
• How to convert date to a format mm/dd/yyyy

This is a more efficient version of the solution from @Kramb. The existence check is redundant as the update where clause already handles this. Instead you just grab the rowcount and compare to batchsize.

Also note @Kramb solution didn't filter out already updated rows from the next iteration hence it would be an infinite loop.

Also uses the modern batch size syntax instead of using rowcount.

DECLARE @batchSize INT, @rowsUpdated INT
SET @batchSize = 1000;
SET @rowsUpdated = @batchSize; -- Initialise for the while loop entry

WHILE (@batchSize = @rowsUpdated)
BEGIN
    UPDATE TOP (@batchSize) TableName
    SET Value = 'abc1'
    WHERE Parameter1 = 'abc' AND Parameter2 = 123 and Value <> 'abc1';

    SET @rowsUpdated = @@ROWCOUNT;
END

Params contains the following three groups of parameters:

1. User supplied parameters
   • GET (http://domain.com/url?param1=value1&param2=value2 will set params[:param1] and params[:param2])
   • POST (e.g. JSON, XML will automatically be parsed and stored in params)
   • Note: By default, Rails duplicates the user supplied parameters and stores them in params[:user] if in UsersController, can be changed with wrap_parameters setting
2. Routing parameters
   • match '/user/:id' in routes.rb will set params[:id]
3. Default parameters
   • params[:controller] and params[:action] is always available and contains the current controller and action

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:

In [16]: import numpy as np

In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()

TypeError: 'numpy.ndarray' object is not callable

If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean or pd.rolling_std to a numpy array earlier in your code.

What I mean is something like this:

In [1]: import numpy as np

In [2]: import pandas as pd

In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan,  nan,  nan])

In [4]: pd.rolling_mean = np.array([1,2,3])

In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...

TypeError: 'numpy.ndarray' object is not callable

So, basically you need to search the rest of your codebase for pd.rolling_mean = ... and/or pd.rolling_std = ... to see where you may have overwritten them.

I think may be you should try to convert the data to json format. It can be done by using gson lib. Try something like below.

I don't know it is a best solutions or not but you could do it this way.It worked for me

example : `

@GET
@Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public Response info(@HeaderParam("Accept") String accept) {
    Info information = new Info();
    information.setInfo("Calc Application Info");
    System.out.println(accept);
    if (!accept.equals(MediaType.APPLICATION_JSON)) {
        return Response.status(Status.ACCEPTED).entity(information).build();
    } else {
        Gson jsonConverter = new GsonBuilder().create();
        return Response.status(Status.ACCEPTED).entity(jsonConverter.toJson(information)).build();
    }
}

This should do it:

ALTER TABLE test MODIFY locationExpert VARCHAR(120) 

Some things of top of my head.

Method 1.

Application.Union(Range("a1"), Range("b1"), Range("d1"), Range("e1"), Range("g1"), Range("h1")).EntireColumn.Select

Method 2.

Range("a1,b1,d1,e1,g1,h1").EntireColumn.Select

Method 3.

Application.Union(Columns("a"), Columns("b"), Columns("d"), Columns("e"), Columns("g"), Columns("h")).Select

You can use os.sep:

>>> import os
>>> os.sep
'/'

You can do this via parsing the user-agent header:

http://php.about.com/od/learnphp/p/http_user_agent.htm

Be wary that this is not very reliable and can be trivially spoofed.

Some might find the below useful:

I wanted clients to be redirected to the login page for any rest-action that is sent without an authorization token. Since all of my rest-actions are Ajax based, I needed a good generic way to redirect to the login page instead of handling the Ajax success function.

This is what I've done:

On any Ajax request my server will return a Json 200 response "NEED TO AUTHENTICATE" (if the client needs to authenticate).

Simple example in Java (server side):

@Secured
@Provider
@Priority(Priorities.AUTHENTICATION)
public class AuthenticationFilter implements ContainerRequestFilter {

    private final Logger m_logger = LoggerFactory.getLogger(AuthenticationFilter.class);

    public static final String COOKIE_NAME = "token_cookie"; 

    @Override
    public void filter(ContainerRequestContext context) throws IOException {        
        // Check if it has a cookie.
        try {
            Map<String, Cookie> cookies = context.getCookies();

            if (!cookies.containsKey(COOKIE_NAME)) {
                m_logger.debug("No cookie set - redirect to login page");
                throw new AuthenticationException();
            }
        }
        catch (AuthenticationException e) {
            context.abortWith(Response.ok("\"NEED TO AUTHENTICATE\"").type("json/application").build());
        }
    }
}

In my Javascript I've added the following code:

$.ajaxPrefilter(function(options, originalOptions, jqXHR) {
    var originalSuccess = options.success;

    options.success = function(data) {
        if (data == "NEED TO AUTHENTICATE") {
            window.location.replace("/login.html");
        }
        else {
            originalSuccess(data);
        }
    };      
});

And that's about it.

As @Alex McMillan mentioned, use state to dictate what should be rendered in the dom.

In the example below I have an input field and I want to add a second one when the user clicks the button, the onClick event handler calls handleAddSecondInput( ) which changes inputLinkClicked to true. I am using a ternary operator to check for the truthy state, which renders the second input field

class HealthConditions extends React.Component {
  constructor(props) {
    super(props);


    this.state = {
      inputLinkClicked: false
    }
  }

  handleAddSecondInput() {
    this.setState({
      inputLinkClicked: true
    })
  }


  render() {
    return(
      <main id="wrapper" className="" data-reset-cookie-tab>
        <div id="content" role="main">
          <div className="inner-block">

            <H1Heading title="Tell us about any disabilities, illnesses or ongoing conditions"/>

            <InputField label="Name of condition"
              InputType="text"
              InputId="id-condition"
              InputName="condition"
            />

            {
              this.state.inputLinkClicked?

              <InputField label=""
                InputType="text"
                InputId="id-condition2"
                InputName="condition2"
              />

              :

              <div></div>
            }

            <button
              type="button"
              className="make-button-link"
              data-add-button=""
              href="#"
              onClick={this.handleAddSecondInput}
            >
              Add a condition
            </button>

            <FormButton buttonLabel="Next"
              handleSubmit={this.handleSubmit}
              linkto={
                this.state.illnessOrDisability === 'true' ?
                "/404"
                :
                "/add-your-details"
              }
            />

            <BackLink backLink="/add-your-details" />

          </div>
         </div>
      </main>
    );
  }
}

Jenkins does not show coverage results as it is a problem of version compatibilities between jenkins jacoco plugin and maven jacoco plugin. On my side I have fixed it by using a more recent version of maven jacoco plugin

<build>
   <pluginManagement>
     <plugins>
       <plugin>
         <groupId>org.jacoco</groupId>
         <artifactId>jacoco-maven-plugin</artifactId>
         <version>0.7.9</version>
       </plugin>
     <plugins>
   <pluginManagement>
<build>

In C/C++ programming there are two types of strings: the C strings and the standard strings. With the <string> header, we can use the standard strings. On the other hand, the C strings are just an array of normal chars. So, in order to convert a standard string to a C string, we use the c_str() function.

for example

// a string to a C-style string conversion//

const char *cstr1 = str1.c_str();
cout<<"Operation: *cstr1 = str1.c_str()"<<endl;
cout<<"The C-style string c_str1 is: "<<cstr1<<endl;
cout<<"\nOperation: strlen(cstr1)"<<endl;
cout<<"The length of C-style string str1 = "<<strlen(cstr1)<<endl;

And the output will be,

Operation: *cstr1 = str1.c_str()
The C-style string c_str1 is: Testing the c_str 
Operation: strlen(cstr1)
The length of C-style string str1 = 17

The command is lowercase: touch filename.

Keep in mind that touch will only create a new file if it does not exist! Here's some docs for good measure: http://unixhelp.ed.ac.uk/CGI/man-cgi?touch

If you always want an empty file, one way to do so would be to use:

echo "" > filename

For numerical addressing of cells try to enable S1O1 checkbox in MS Excel settings. It is the second tab from top (i.e. Formulas), somewhere mid-page in my Hungarian version.

If enabled, it handles VBA addressing in both styles, i.e. Range("A1:B10") and Range(Cells(1, 1), Cells(10, 2)). I assume it handles Range("A1:B10") style only, if not enabled.

Good luck!

(Note, that Range("A1:B10") represents a 2x10 square, while Range(Cells(1, 1), Cells(10, 2)) represents 10x2. Using column numbers instead of letters will not affect the order of addresing.)

try:

RewriteRule ^/apple(.*)?$ /folder1$1 [NC]

Where the folder you want to appear in the url is in the first part of the statement - this is what it will match against and the second part 'rewrites' it to your existing folder. the [NC] flag means that it will ignore case differences eg Apple/ will still forward.

See here for a tutorial: http://www.sitepoint.com/article/guide-url-rewriting/

There is also a nice test utility for windows you can download from here: http://www.helicontech.com/download/rxtest.zip Just to note for the tester you need to leave out the domain name - so the test would be against /folder1/login.php

to redirect from /folder1 to /apple try this:

RewriteRule ^/folder1(.*)?$ /apple$1 [R]

to redirect and then rewrite just combine the above in the htaccess file:

RewriteRule ^/folder1(.*)?$ /apple$1 [R]
RewriteRule ^/apple(.*)?$ /folder1$1 [NC]

This isn't a single JSON object. You have an array of JSON objects. You need to loop over array first and then access each object. Maybe the following kickoff example is helpful:

var arrayOfObjects = [{
  "id": 28,
  "Title": "Sweden"
}, {
  "id": 56,
  "Title": "USA"
}, {
  "id": 89,
  "Title": "England"
}];

for (var i = 0; i < arrayOfObjects.length; i++) {
  var object = arrayOfObjects[i];
  for (var property in object) {
    alert('item ' + i + ': ' + property + '=' + object[property]);
  }
  // If property names are known beforehand, you can also just do e.g.
  // alert(object.id + ',' + object.Title);
}

If the array of JSON objects is actually passed in as a plain vanilla string, then you would indeed need eval() here.

var string = '[{"id":28,"Title":"Sweden"}, {"id":56,"Title":"USA"}, {"id":89,"Title":"England"}]';
var arrayOfObjects = eval(string);
// ...

In my case the server were the service was installed was configured only for TLS. SSL was not allowed. So you have to update SoapUI vmoptions file by adding

-Dsoapui.https.protocols=TLSv1.2

You can find vmoptions file under SoapUI installation folder:

C:\Program Files (x86)\SmartBear\SoapUI-5.0.0\bin\soapUI-5.0.0.vmoptions

OR change your server setting to allow SSL

From the npm-link documentation:

In the local module directory:

$ cd ./package-dir
$ npm link

In the directory of the project to use the module:

$ cd ./project-dir
$ npm link package-name

Or in one go using relative paths:

$ cd ./project-dir
$ npm link ../package-dir

This is equivalent to using two commands above under the hood.

Set to null. Then there are no references anymore and the object will become eligible for Garbage Collection. GC will automatically remove the object from the heap.

To remove the variable from the current environment (not permanently):

set FOOBAR=

To permanently remove the variable from the user environment (which is the default place setx puts it):

REG delete HKCU\Environment /F /V FOOBAR

If the variable is set in the system environment (e.g. if you originally set it with setx /M), as an administrator run:

REG delete "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /F /V FOOBAR

Note: The REG commands above won't affect any existing processes (and some new processes that are forked from existing processes), so if it's important for the change to take effect immediately, the easiest and surest thing to do is log out and back in or reboot. If this isn't an option or you want to dig deeper, some of the other answers here have some great suggestions that may suit your use case.

Here's a simple/sinister one via http://wiki.eclipse.org/Performance_Bloopers#String.substring.28.29.

public class StringLeaker
{
    private final String muchSmallerString;

    public StringLeaker()
    {
        // Imagine the whole Declaration of Independence here
        String veryLongString = "We hold these truths to be self-evident...";

        // The substring here maintains a reference to the internal char[]
        // representation of the original string.
        this.muchSmallerString = veryLongString.substring(0, 1);
    }
}

Because the substring refers to the internal representation of the original, much longer string, the original stays in memory. Thus, as long as you have a StringLeaker in play, you have the whole original string in memory, too, even though you might think you're just holding on to a single-character string.

The way to avoid storing an unwanted reference to the original string is to do something like this:

...
this.muchSmallerString = new String(veryLongString.substring(0, 1));
...

For added badness, you might also .intern() the substring:

...
this.muchSmallerString = veryLongString.substring(0, 1).intern();
...

Doing so will keep both the original long string and the derived substring in memory even after the StringLeaker instance has been discarded.

Basic implementation using MultipartFormDataContent :-

HttpClient httpClient = new HttpClient();
MultipartFormDataContent form = new MultipartFormDataContent();

form.Add(new StringContent(username), "username");
form.Add(new StringContent(useremail), "email");
form.Add(new StringContent(password), "password");            
form.Add(new ByteArrayContent(file_bytes, 0, file_bytes.Length), "profile_pic", "hello1.jpg");
HttpResponseMessage response = await httpClient.PostAsync("PostUrl", form);

response.EnsureSuccessStatusCode();
httpClient.Dispose();
string sd = response.Content.ReadAsStringAsync().Result;

You can do that for your entire script by using something like that at the beginning of your script :

#!/usr/bin/env bash

test x$1 = x$'\x00' && shift || { set -o pipefail ; ( exec 2>&1 ; $0 $'\x00' "$@" ) | tee mylogfile ; exit $? ; }

# do whaetever you want

This redirect both stderr and stdout outputs to the file called mylogfile and let everything goes to stdout at the same time.

It is used some stupid tricks :

• use exec without command to setup redirections,
• use tee to duplicates outputs,
• restart the script with the wanted redirections,
• use a special first parameter (a simple NUL character specified by the $'string' special bash notation) to specify that the script is restarted (no equivalent parameter may be used by your original work),
• try to preserve the original exit status when restarting the script using the pipefail option.

Ugly but useful for me in certain situations.

If having the directory already exist is not a problem for you, you could just redirect stderr for that command, getting rid of the error message:

-mkdir $(OBJDIR) 2>/dev/null

Try this

DateTime dDate;
dDate = DateTime.TryParse(inputString);
String.Format("{0:d/MM/yyyy}", dDate);

If you are working in Windows you have to change the permissions of the directory putting full permissions or just write to let github clone the repository. The steps are:

1. Go To your directory
2. open properties
3. go to tab "security"
4. change the permissions
5. apply

Here is an example of data binding with AngularJS, using an input field. I will explain later

HTML Code

<div ng-app="myApp" ng-controller="myCtrl" class="formInput">
     <input type="text" ng-model="watchInput" Placeholder="type something"/>
     <p>{{watchInput}}</p> 
</div>

AngularJS Code

myApp = angular.module ("myApp", []);
myApp.controller("myCtrl", ["$scope", function($scope){
  //Your Controller code goes here
}]);

As you can see in the example above, AngularJS uses ng-model to listen and watch what happens on HTML elements, especially on input fields. When something happens, do something. In our case, ng-model is bind to our view, using the mustache notation {{}}. Whatever is typed inside the input field is displayed on the screen instantly. And that's the beauty of data binding, using AngularJS in its simplest form.

Hope this helps.

See a working example here on Codepen

I wanted to extend the answers already given to include support for dynamically connected devices that aren't captured with /dev/bus/usb and how to get this working when using a Windows host along with the boot2docker VM.

If you are working with Windows, you'll need to add any USB rules for devices that you want Docker to access within the VirtualBox manager. To do this you can stop the VM by running:

host:~$ docker-machine stop default

Open the VirtualBox Manager and add USB support with filters as required.

Start the boot2docker VM:

host:~$ docker-machine start default

Since the USB devices are connected to the boot2docker VM, the commands need to be run from that machine. Open up a terminal with the VM and run the docker run command:

host:~$ docker-machine ssh
docker@default:~$ docker run -it --privileged ubuntu bash

Note, when the command is run like this, then only previously connected USB devices will be captures. The volumes flag is only required if you want this to work with devices connected after the container is started. In that case, you can use:

docker@default:~$ docker run -it --privileged -v /dev:/dev ubuntu bash

Note, I had to use /dev instead of /dev/bus/usb in some cases to capture a device like /dev/sg2. I can only assume the same would be true for devices like /dev/ttyACM0 or /dev/ttyUSB0.

The docker run commands will work with a Linux host as well.

You cannot mix JS and PHP that way, PHP is rendered before the page is sent to the browser (i.e. before the JS is run)

You can use window.location to change your current page.

$('.entry a:first').click(function() {
    window.location = "http://google.ca";
});

You may do it by using following code:

var url = "www.site.com/index.php#hello";
var hash = url.substring(url.indexOf('#')+1);
alert(hash);

SEE DEMO

You can try this

var element = document.getElementById('element_id');
element.style.backgroundColor = "color or color_code";

Example.

var element = document.getElementById('firstname');
element.style.backgroundColor = "green";//Or #ff55ff

JSFIDDLE

The following is the complete example containing both XML and XSLT where substring-before and substring-after are used

<?xml version="1.0" encoding="UTF-8"?>
<persons name="Group_SOEM">
    <person>
        <first>Joe Smith</first>
        <last>Joe Smith</last>
        <address>123 Main St, Anycity</address>
    </person>
</persons>    

The following is XSLT which changes value of first/last name by separating the value by space so that after applying this XSL the first name element will have value "Joe" and last "Smith".

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="first">
    <first>
        <xsl:value-of select="substring-before(.,' ')" />
    </first>
</xsl:template> 
<xsl:template match="last">
    <last>
        <xsl:value-of select="substring-after(.,' ')" />
    </last>
</xsl:template> 
<xsl:template match="@* | node()">
    <xsl:copy>
        <xsl:apply-templates select="@* | node()" />
    </xsl:copy>
</xsl:template>
</xsl:stylesheet>   

for winforms .NET change DropDownStyle to DropDownList from Combobox property

X-code is primarily made for OS-X or iPhone development on Mac systems. Versions for Windows are not available. However this might help!

There is no way to get Xcode on Windows; however you can use a different SDK like Corona instead although it will not use Objective-C (I believe it uses Lua). I have however heard that it is horrible to use.

This worked:

$("#theSelectId").prepend("<option value='' selected='selected'></option>");

Firebug Output:

<select id="theSelectId">
  <option selected="selected" value=""/>
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="mercedes">Mercedes</option>
  <option value="audi">Audi</option>
</select>

You could also use .prependTo if you wanted to reverse the order:

?$("<option>", { value: '', selected: true }).prependTo("#theSelectId");???????????

You can use this one it's for YYYY-MM-DD. It checks if it's a valid date and that the value is not NULL. It returns TRUE if everythings check out to be correct or FALSE if anything is invalid. It doesn't get easier then this!

function validateDate(date) {
    var matches = /^(\d{4})[-\/](\d{2})[-\/](\d{2})$/.exec(date);
    if (matches == null) return false;
    var d = matches[3];
    var m = matches[2] - 1;
    var y = matches[1] ;
    var composedDate = new Date(y, m, d);
    return composedDate.getDate() == d &&
            composedDate.getMonth() == m &&
            composedDate.getFullYear() == y;
}

Be aware that months need to be subtracted like this: var m = matches[2] - 1; else the new Date() instance won't be properly made.

Hide doesn't close the window, just put in visible mode. The best solution was:

@FXML
private void exitButtonOnAction(ActionEvent event){
        ((Stage)(((Button)event.getSource()).getScene().getWindow())).close();      
}

The best way to resolve this one is. Download the latest container-selinux package from http://mirror.centos.org/centos/7/extras/x86_64/Packages/ into the VM or the Machine where docker needs to be installed. Error : sometime it will ask for red hat subscription to download from repo. we can do it manually with out subscription as below Run the below command this will install dependencies manually rpm -i container-selinux-2.107-3.el7.noarch.rpm then run the yum install docker-ce

thanks Saa

Once you have Selected a group of sheets, you can use Selection

Consider:

Sub luxation()
    ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
    Selection.ExportAsFixedFormat _
        Type:=xlTypePDF, _
        Filename:="C:\TestFolder\temp.pdf", _
        Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, _
        IgnorePrintAreas:=False, _
        OpenAfterPublish:=True
End Sub

EDIT#1:

Further testing has reveled that this technique depends on the group of cells selected on each worksheet. To get a comprehensive output, use something like:

Sub Macro1()

   Sheets("Sheet1").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet2").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet3").Activate
   ActiveSheet.UsedRange.Select

   ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
   Selection.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
      "C:\Users\James\Desktop\pdfmaker.pdf", Quality:=xlQualityStandard, _
      IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
      True
End Sub

Nowadays String.prototype.split does indeed allow you to limit the number of splits.

str.split([separator[, limit]])

...

limit Optional

A non-negative integer limiting the number of splits. If provided, splits the string at each occurrence of the specified separator, but stops when limit entries have been placed in the array. Any leftover text is not included in the array at all.

The array may contain fewer entries than limit if the end of the string is reached before the limit is reached. If limit is 0, no splitting is performed.

caveat

It might not work the way you expect. I was hoping it would just ignore the rest of the delimiters, but instead, when it reaches the limit, it splits the remaining string again, omitting the part after the split from the return results.

let str = 'A_B_C_D_E'
const limit_2 = str.split('_', 2)
limit_2
(2) ["A", "B"]
const limit_3 = str.split('_', 3)
limit_3
(3) ["A", "B", "C"]

I was hoping for:

let str = 'A_B_C_D_E'
const limit_2 = str.split('_', 2)
limit_2
(2) ["A", "B_C_D_E"]
const limit_3 = str.split('_', 3)
limit_3
(3) ["A", "B", "C_D_E"]

This can mean a lot of things, but the most common one is that the class contained in the file doesn't have the same name as the file itself. So, check if your class is also called HelloWorld2.

Select * from Table1 left join Table2 ...

and

Select * from Table2 right join Table1 ...

are indeed completely interchangeable. Try however Table2 left join Table1 (or its identical pair, Table1 right join Table2) to see a difference. This query should give you more rows, since Table2 contains a row with an id which is not present in Table1.

While you are working with Laravel you must be in root of laravel directory structure. There are App, route, public etc folders is root directory. Just follow below step to fix issue. check composer status using : composer -v

First, download the Laravel installer using Composer:

composer global require "laravel/installer"

Please check with below command:

php artisan serve
