I set CurrentCulture and CurrentUICulture my custom base controller

    protected override void Initialize(RequestContext requestContext)
    {
        base.Initialize(requestContext);

        Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("en-GB");
        Thread.CurrentThread.CurrentUICulture = CultureInfo.GetCultureInfo("en-GB");
    }

Try this:

- (void)tableView:(UITableView *)tableView1 willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
    [cell setBackgroundColor:[UIColor clearColor]];
    tableView1.backgroundColor = [UIColor colorWithPatternImage: [UIImage imageNamed: @"Cream.jpg"]];
}

Handler h = new Handler() {
    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);
        if (msg.what==0){
            // do stuff
            h.removeMessages(0);  // clear the handler for those messages with what = 0
            h.sendEmptyMessageDelayed(0, 2000); 
        }
    }
};


 h.sendEmptyMessage(0);  

Try this instead:

select xmltype(t.xml).extract('//fax/text()').getStringVal() from mytab t

This worked for SQL Server 2005, 2008, and 2012. I found that the sys.identity_columns did not contain all my tables with identity columns.

SELECT a.name AS TableName, b.name AS IdentityColumn
FROM sys.sysobjects a 
JOIN sys.syscolumns b 
ON a.id = b.id
WHERE is_identity = 1
ORDER BY name;

Looking at the documentation page the status column can also be utilized. Also you can add the four part identifier and it will work across different servers.

SELECT a.name AS TableName, b.name AS IdentityColumn
FROM [YOUR_SERVER_NAME].[YOUR_DB_NAME].sys.sysobjects a 
JOIN [YOUR_SERVER_NAME].[YOUR_DB_NAME].sys.syscolumns b 
ON a.id = b.id
WHERE is_identity = 1
ORDER BY name;

There's really no reason to remove ruby1-8, unless someone else knows better. Execute the commands below to install 1.9 and then link ruby to point to the new version.

sudo apt-get install ruby1-9 rubygems1-9
sudo ln -sf /usr/bin/ruby1-9 /usr/bin/ruby

That's because you should pass a function, not a string:

function funcName() {
    alert("test");
}

setInterval(funcName, 10000);

Your code has two problems:

• var func = funcName(); calls the function immediately and assigns the return value.
• Just "func" is invalid even if you use the bad and deprecated eval-like syntax of setInterval. It would be setInterval("func()", 10000) to call the function eval-like.

An alternative solution I found before I knew the correct answer was to add a transparent border to the parent element.

Your box will use extra pixels though...

.parent {
    border:1px solid transparent;
}

Whilst this an old question, I ran into this problem myself recently and some of the answers here are now deprecated (as the comments point out). So for the benefit of others who may have stumbled here:

A term query can be used to find the exact term specified in the reverse index:

{
  "query": {
   "term" : { "tags" : "a" }
} 

From the documenation https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-term-query.html

Alternatively you can use a terms query, which will match all documents with any of the items specified in the given array:

{
  "query": {
   "terms" : { "tags" : ["a", "c"]}
} 

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html

One gotcha to be aware of (which caught me out) - how you define the document also makes a difference. If the field you're searching in has been indexed as a text type then Elasticsearch will perform a full text search (i.e using an analyzed string).

If you've indexed the field as a keyword then a keyword search using a 'non-analyzed' string is performed. This can have a massive practical impact as Analyzed strings are pre-processed (lowercased, punctuation dropped etc.) See (https://www.elastic.co/guide/en/elasticsearch/guide/master/term-vs-full-text.html)

To avoid these issues, the string field has split into two new types: text, which should be used for full-text search, and keyword, which should be used for keyword search. (https://www.elastic.co/blog/strings-are-dead-long-live-strings)

Just to add to the other answers, there are still noteworthy differences here, specifically when dealing with <svg> elements.

I have used both .childNodes and .children and have preferred working with the HTMLCollection delivered by the .children getter.

Today however, I ran into issues with IE/Edge failing when using .children on an <svg>. While .children is supported in IE on basic HTML elements, it isn't supported on document/document fragments, or SVG elements.

For me, I was able to simply grab the needed elements via .childNodes[n] because I don't have extraneous text nodes to worry about. You may be able to do the same, but as mentioned elsewhere above, don't forget that you may run into unexpected elements.

Hope this is helpful to someone scratching their head trying to figure out why .children works elsewhere in their js on modern IE and fails on document or SVG elements.

Are you running on Linux? Perhaps the management agent is binding to localhost:

http://java.sun.com/j2se/1.5.0/docs/guide/management/faq.html#linux1

Use SimpleDateFormat#format:

DateFormat originalFormat = new SimpleDateFormat("MMMM dd, yyyy", Locale.ENGLISH);
DateFormat targetFormat = new SimpleDateFormat("yyyyMMdd");
Date date = originalFormat.parse("August 21, 2012");
String formattedDate = targetFormat.format(date);  // 20120821

Also note that parse takes a String, not a Date object, which is already parsed.

you code is fine but never executed, cause of submit button [type="submit"] just replace it by type=button

<input value="Submit" type="button" onclick="submitform()">

inside your script; form is not declared.

let form = document.forms[0];
xhr.open(form.method, form.action, true);

You can do this:

cat("File not supplied.\nUsage: ./program F=filename\n")

Notice that cat has a return value of NULL.

The negated set of everything that is not alphanumeric & underscore for ASCII chars:

/[^\W]/g

For email or username validation i've used the following expression that allows 4 standard special characters - _ . @

/^[-.@_a-z0-9]+$/gi

For a strict alphanumeric only expression use:

/^[a-z0-9]+$/gi

Test @ RegExr.com

In a Batch File you MUST use %% instead of % : (Type help for)

for /F "tokens=1,2,3" %%i in (myfile.txt) do call :process %%i %%j %%k
goto thenextstep
:process
set VAR1=%1
set VAR2=%2
set VAR3=%3
COMMANDS TO PROCESS INFORMATION
goto :EOF

What this does: The "do call :process %%i %%j %%k" at the end of the for command passes the information acquired in the for command from myfile.txt to the "process" 'subroutine'.

When you're using the for command in a batch program, you need to use double % signs for the variables.

The following lines pass those variables from the for command to the process 'sub routine' and allow you to process this information.

set VAR1=%1
 set VAR2=%2
 set VAR3=%3

I have some pretty advanced uses of this exact setup that I would be willing to share if further examples are needed. Add in your EOL or Delims as needed of course.

My favorite is to use the .Net [IO.DirectoryInfo] class, which takes care of some of the logic. I actually use this for a lot of similar scripting challenges. It has a .Create() method that creates directories that don't exist, without errors if they do.

Since this is still a two step problem, I use the foreach alias to keep it simple. For single files:

[IO.DirectoryInfo]$to |% {$_.create(); cp $from $_}

As far as your multi file/directory match, I would use RoboCopy over xcopy. Remove the "*" from your from and just use:

RoboCopy.exe $from $to *

You can still add the /r (Recurse), /e (Recurse including Empty), and there are 50 other useful switches.

Edit: Looking back at this it is terse, but not very readable if you are not using the code often. Usually I have it split into two, like so:

([IO.DirectoryInfo]$to).Create()
cp $from $to

Also, DirectoryInfo is the type of the Parent property of FileInfo, so if your $to is a file, you can use them together:

([IO.FileInfo]$to).Parent.Create()
cp $from $to

Yes, there's str_to_date

mysql> select str_to_date("03/02/2009","%d/%m/%Y");
+--------------------------------------+
| str_to_date("03/02/2009","%d/%m/%Y") |
+--------------------------------------+
| 2009-02-03                           |
+--------------------------------------+
1 row in set (0.00 sec)

This will work:

select * into DestinationDatabase.dbo.[TableName1] from (
Select * from sourceDatabase.dbo.[TableName1])Temp

In order to install Compass on Yosemite you need to set up the Ruby environment and to install the Xcode Command Line Tools. But, most important thing, after updating Xcode, be sure to launch the Xcode application and accept the Apple license terms. It will complete the installation of the components. After that, you can install Compass: sudo gem install compass

SQL Server Management Studio 2005

When you right click on a database and click Tasks and then click Detach Database, it brings up a dialog with the active connections.

By clicking on the hyperlink under "Messages" you can kill the active connections.

You can then kill those connections without detaching the database.

More information here.

SQL Server Management Studio 2008

The interface has changed for SQL Server Management studio 2008, here are the steps (via: Tim Leung)

1. Right-click the server in Object Explorer and select 'Activity Monitor'.
2. When this opens, expand the Processes group.
3. Now use the drop-down to filter the results by database name.
4. Kill off the server connections by selecting the right-click 'Kill Process' option.

For many people working with node.js, a major benefit of bower is for managing dependencies that are not javascript at all. If they are working with languages that compile to javascript, npm can be used to manage some of their dependencies. however, not all their dependencies are going to be node.js modules. Some of those that compile to javascript may have weird source language specific mangling that makes passing them around compiled to javascript an inelegant option when users are expecting source code.

Not everything in an npm package needs to be user-facing javascript, but for npm library packages, at least some of it should be.

I'm having exacty the same problem and using probably the same tutorial. The function definition:

def read(*rnames):
    return open(os.path.join(os.path.dirname(__file__), *rnames)).read()

is buggy, since os.path.dirname(__file__) will not return what you need. Try replacing os.path.dirname(__file__) with os.path.dirname(os.path.abspath(__file__)):

def read(*rnames):
    return open(os.path.join(os.path.dirname(os.path.abspath(__file__)), *rnames)).read()

I've just posted Andrew that the code snippet in current docs don't work, hopefully, it'll be corrected.

CONNECTION_REFUSED is standard when the port is closed, but it could be rejected because SSL is failing authentication (one of a billion reasons). Did you configure SSL with Ratchet? (Apache is bypassed) Did you try without SSL in JavaScript?

I don't think Ratchet has built-in support for SSL. But even if it does you'll want to try the ws:// protocol first; it's a lot simpler, easier to debug, and closer to telnet. Chrome or the socket service may also be generating the REFUSED error if the service doesn't support SSL (because you explicitly requested SSL).

However the refused message is likely a server side problem, (usually port closed).

break breaks out of a loop, not an if statement, as others have pointed out. The motivation for this isn't too hard to see; think about code like

for item in some_iterable:
    ...
    if break_condition():
        break 

The break would be pretty useless if it terminated the if block rather than terminated the loop -- terminating a loop conditionally is the exact thing break is used for.

You can simply use matches method of String class.

boolean result = someString.matches("stores.*store.*product.*");

The chapter on CAST and CONVERT on MSDN Books Online, you've missed the right answer by one line.... you can use style no. 121 (ODBC canonical (with milliseconds)) to get the result you're looking for:

SELECT CONVERT(VARCHAR(30), GETDATE(), 121)

This gives me the output of:

2012-04-14 21:44:03.793

Update: based on your updated question - of course this won't work - you're converting a string (this: '4/14/2012 2:44:01 PM' is just a string - it's NOT a datetime!) to a string......

You need to first convert the string you have to a DATETIME and THEN convert it back to a string!

Try this:

SELECT CONVERT(VARCHAR(30), CAST('4/14/2012 2:44:01 PM' AS DATETIME), 121) 

Now you should get:

2012-04-14 14:44:01.000

All zeroes for the milliseconds, obviously, since your original values didn't include any ....

The error message tells the exact reason: "abstract methods cannot have a body".

They can only be defined in abstract classes and interfaces (interface methods are implicitly abstract!) and the idea is, that the subclass implements the method.

Example:

 public abstract class AbstractGreeter {
   public abstract String getHelloMessage();

   public void sayHello() {
     System.out.println(getHelloMessage());
   }
 }

 public class FrenchGreeter extends AbstractGreeter{

   // we must implement the abstract method
   @Override
   public String getHelloMessage() {
     return "bonjour";
   }
 }

@DCookie

I just want to point out that you can leave off the lines that say

EXCEPTION  
  WHEN OTHERS THEN    
    RAISE;

You'll get the same effect if you leave off the exception block all together, and the line number reported for the exception will be the line where the exception is actually thrown, not the line in the exception block where it was re-raised.

Check out the addressable gem - a popular replacement for Ruby's URI module that makes query parsing easy:

require "addressable/uri"
uri = Addressable::URI.parse("http://www.example.com/something?param1=value1&param2=value2&param3=value3")
uri.query_values['param1']
=> 'value1'

(It also apparently handles param encoding/decoding, unlike URI)

You could use char.IsDigit:

     bool isIntString = "your string".All(char.IsDigit)

Will return true if the string is a number

    bool containsInt = "your string".Any(char.IsDigit)

Will return true if the string contains a digit

Swift 5 provides a method called enumerated() for Array. enumerated() has the following declaration:

func enumerated() -> EnumeratedSequence<Array<Element>>

Returns a sequence of pairs (n, x), where n represents a consecutive integer starting at zero and x represents an element of the sequence.

In the simplest cases, you may use enumerated() with a for loop. For example:

let list = ["Car", "Bike", "Plane", "Boat"]
for (index, element) in list.enumerated() {
    print(index, ":", element)
}

/*
prints:
0 : Car
1 : Bike
2 : Plane
3 : Boat
*/

Note however that you're not limited to use enumerated() with a for loop. In fact, if you plan to use enumerated() with a for loop for something similar to the following code, you're doing it wrong:

let list = [Int](1...5)
var arrayOfTuples = [(Int, Int)]()

for (index, element) in list.enumerated() {
    arrayOfTuples += [(index, element)]
}

print(arrayOfTuples) // prints [(0, 1), (1, 2), (2, 3), (3, 4), (4, 5)]

A swiftier way to do this is:

let list = [Int](1...5)
let arrayOfTuples = Array(list.enumerated())
print(arrayOfTuples) // prints [(offset: 0, element: 1), (offset: 1, element: 2), (offset: 2, element: 3), (offset: 3, element: 4), (offset: 4, element: 5)]

As an alternative, you may also use enumerated() with map:

let list = [Int](1...5)
let arrayOfDictionaries = list.enumerated().map { (a, b) in return [a : b] }
print(arrayOfDictionaries) // prints [[0: 1], [1: 2], [2: 3], [3: 4], [4: 5]]

Moreover, although it has some limitations, forEach can be a good replacement to a for loop:

let list = [Int](1...5)
list.reversed().enumerated().forEach { print($0, ":", $1) }

/*
prints:
0 : 5
1 : 4
2 : 3
3 : 2
4 : 1
*/

By using enumerated() and makeIterator(), you can even iterate manually on your Array. For example:

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    var generator = ["Car", "Bike", "Plane", "Boat"].enumerated().makeIterator()

    override func viewDidLoad() {
        super.viewDidLoad()

        let button = UIButton(type: .system)
        button.setTitle("Tap", for: .normal)
        button.frame = CGRect(x: 100, y: 100, width: 100, height: 100)
        button.addTarget(self, action: #selector(iterate(_:)), for: .touchUpInside)
        view.addSubview(button)
    }

    @objc func iterate(_ sender: UIButton) {
        let tuple = generator.next()
        print(String(describing: tuple))
    }

}

PlaygroundPage.current.liveView = ViewController()

/*
 Optional((offset: 0, element: "Car"))
 Optional((offset: 1, element: "Bike"))
 Optional((offset: 2, element: "Plane"))
 Optional((offset: 3, element: "Boat"))
 nil
 nil
 nil
 */

change them to rows

rows = zip(list1,list2,list3,list4,list5)

then just

import csv

with open(newfilePath, "w") as f:
    writer = csv.writer(f)
    for row in rows:
        writer.writerow(row)

If you manage the IIS and you are the one who have to create new site then check the "Application Pool" and be sure the CLR version must be selected. In my situation, it had been selected "No Managed Code". After changed to v4.0 it started to work.

In short I would say no, the juice is not worth the squeeze to test a service method with a single line that retrieves model data. In my experience people who are new to TDD want to test absolutely everything. The old chestnut of abstracting a facade to a 3rd party framework just so you can create a mock of that frameworks API with which you bastardise/extend so that you can inject dummy data is of little value in my mind. Everyone has a different view of how much unit testing is best. I tend to be more pragmatic these days and ask myself if my test is really adding value to the end product, and at what cost.

The trick is to visit the original page using the 64-bit version of Internet Explorer. The site will then offer you the appropriate download options.

You got an answer but in your case you can use

return empty($input);

or

return is_string($input);

Take a look at Linq-to-Excel. It's pretty neat.

var book = new LinqToExcel.ExcelQueryFactory(@"File.xlsx");

var query =
    from row in book.Worksheet("Stock Entry")
    let item = new
    {
        Code = row["Code"].Cast<string>(),
        Supplier = row["Supplier"].Cast<string>(),
        Ref = row["Ref"].Cast<string>(),
    }
    where item.Supplier == "Walmart"
    select item;

It also allows for strongly-typed row access too.

like this?

DF <- data.frame("a" = as.character(0:5),
             "b" = paste(0:5, ".1", sep = ""),
             "c" = paste(10:15),
             stringsAsFactors = FALSE)

DF <- apply(DF, 2, as.numeric)

If there are "real" characters in dataframe like 'a' 'b' 'c', i would recommend answer from davsjob.

Extra Tips:

Multiple "nots", input that is NOT hidden and NOT disabled:

:not([type="hidden"]):not([disabled])

Also did you know you can do this:

node.parentNode.querySelectorAll('div');

This is equivelent to jQuery's:

$(node).parent().find('div');

Which will effectively find all divs in "node" and below recursively, HOT DAMN!

With Spring Boot its not necessary to have any config file like persistence.xml. You can configure with annotations Just configure your DB config for JPA in the

application.properties

spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@DB...
spring.datasource.username=username
spring.datasource.password=pass

spring.jpa.database-platform=org.hibernate.dialect....
spring.jpa.show-sql=true

Then you can use CrudRepository provided by Spring where you have standard CRUD transaction methods. There you can also implement your own SQL's like JPQL.

@Transactional
public interface ObjectRepository extends CrudRepository<Object, Long> {
...
}

And if you still need to use the Entity Manager you can create another class.

public class ObjectRepositoryImpl implements ObjectCustomMethods{

    @PersistenceContext
    private EntityManager em;

}

This should be in your pom.xml

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.5.RELEASE</version>

        <version>4.3.11.Final</version>
    </dependency>
</dependencies>

df[df['Value']==df['Value'].max()]

This will return the entire row with max value

You can also do this.

//find the index of the CompanyName column
int columnIndex = thisReader.GetOrdinal("CompanyName"); 
//Get the value of the column. Will throw if the value is null.
string companyName = thisReader.GetString(columnIndex);

I want to share the one I am using:

import time
# provide a waiting-time list:
lst = [1,2,7,4,5,6,4,3]
# set the timeout limit
timeLimit = 4

for i in lst:
    timeCheck = time.time()
    while True:
        time.sleep(i)
        if time.time() <= timeCheck + timeLimit:
            print ([i,'looks ok'])
            break
        else:
            print ([i,'too long'])
            break

Then you will get:

[1, 'looks ok']
[2, 'looks ok']
[7, 'too long']
[4, 'looks ok']
[5, 'too long']
[6, 'too long']
[4, 'looks ok']
[3, 'looks ok']

No, there's no direct method to do that with objects.

The Map type does have a values() method that returns an iterator for the values

Here are the two main approaches. I prefer this one for its readability:

bar <- subset(foo, location == "there")

Note that you can string together many conditionals with & and | to create complex subsets.

The second is the indexing approach. You can index rows in R with either numeric, or boolean slices. foo$location == "there" returns a vector of T and F values that is the same length as the rows of foo. You can do this to return only rows where the condition returns true.

foo[foo$location == "there", ]

Try using the command: git status

beforeShowDate didn't work for me, so I went ahead and developed my own solution:

$('#embeded_calendar').datepicker({
               minDate: date,
                localToday:datePlusOne,
               changeDate: true,
               changeMonth: true,
               changeYear: true,
               yearRange: "-120:+1",
               onSelect: function(selectedDateFormatted){

                     var selectedDate = $("#embeded_calendar").datepicker('getDate');

                    deactivateDates(selectedDate);
                   }

           });


              var excludedDates = [ "10-20-2017","10-21-2016", "11-21-2016"];

              deactivateDates(new Date());

            function deactivateDates(selectedDate){
                setTimeout(function(){ 
                      var thisMonthExcludedDates = thisMonthDates(selectedDate);
                      thisMonthExcludedDates = getDaysfromDate(thisMonthExcludedDates);
                       var excludedTDs = page.find('td[data-handler="selectDay"]').filter(function(){

I had to solve a similar problem--I wanted certain styles to only apply to mobile devices in landscape mode. Essentially the fonts and line spacing looked fine in every other context, so I just needed the one exception for mobile landscape. This media query worked perfectly:

@media all and (max-width: 600px) and (orientation:landscape) 
{
    /* styles here */
}

Pass it as an Object:

$(....).css({
    'property': 'value', 
    'property': 'value'
});

http://docs.jquery.com/CSS/css#properties

This is because you are referring to property of controller named HttpContext. To access the current context use full class name:

System.Web.HttpContext.Current

However this is highly not recommended to access context like this in ASP.NET MVC, so yes, you can think of System.Web.HttpContext.Current as being deprecated inside ASP.NET MVC. The correct way to access current context is

this.ControllerContext.HttpContext

or if you are inside a Controller, just use member

this.HttpContext

tl;dr: (try it here)

If you have the following HTML:

<div id="menu" style="display: none;">
   <!-- menu stuff in here -->
   <ul><li>Menu item</li></ul>
</div>

<div class="parent">Hover over me to show the menu here</div>

then you can use the following JavaScript code:

$(".parent").mouseover(function() {
    // .position() uses position relative to the offset parent, 
    var pos = $(this).position();

    // .outerWidth() takes into account border and padding.
    var width = $(this).outerWidth();

    //show the menu directly over the placeholder
    $("#menu").css({
        position: "absolute",
        top: pos.top + "px",
        left: (pos.left + width) + "px"
    }).show();
});

But it doesn't work!

This will work as long as the menu and the placeholder have the same offset parent. If they don't, and you don't have nested CSS rules that care where in the DOM the #menu element is, use:

$(this).append($("#menu"));

just before the line that positions the #menu element.

But it still doesn't work!

You might have some weird layout that doesn't work with this approach. In that case, just use jQuery.ui's position plugin (as mentioned in an answer below), which handles every conceivable eventuality. Note that you'll have to show() the menu element before calling position({...}); the plugin can't position hidden elements.

Update notes 3 years later in 2012:

(The original solution is archived here for posterity)

So, it turns out that the original method I had here was far from ideal. In particular, it would fail if:

• the menu's offset parent is not the placeholder's offset parent
• the placeholder has a border/padding

Luckily, jQuery introduced methods (position() and outerWidth()) way back in 1.2.6 that make finding the right values in the latter case here a lot easier. For the former case, appending the menu element to the placeholder works (but will break CSS rules based on nesting).

You can also set

-Djava.net.useSystemProxies=true

On Windows and Linux this will use the system settings so you don't need to repeat yourself (DRY)

http://docs.oracle.com/javase/7/docs/api/java/net/doc-files/net-properties.html#Proxies

You can use COALESCE in conjunction with NULLIF for a short, efficient solution:

COALESCE( NULLIF(yourField,'') , '0' )

The NULLIF function will return null if yourField is equal to the second value ('' in the example), making the COALESCE function fully working on all cases:

                 QUERY                     |                RESULT 
---------------------------------------------------------------------------------
SELECT COALESCE(NULLIF(null  ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF(''    ,''),'0')     |                 '0'
SELECT COALESCE(NULLIF('foo' ,''),'0')     |                 'foo'

The same, if you need "generic" regex from string :

const textTitle = "this is a test";_x000D_
const regEx = new RegExp(' ', "g");_x000D_
const result = textTitle.replace(regEx , '%20');_x000D_
console.log(result); // "this%20is%20a%20test" will be a result_x000D_
    

It sounds like you want to use this web application as a remote control for your robot, and a core issue is that you won't want a page reload every time you perform an action, in which case, the last link you posted answers your problem.

I think you may be misunderstanding a few things about Flask. For one, you can't nest multiple functions in a single route. You're not making a set of functions available for a particular route, you're defining the one specific thing the server will do when that route is called.

With that in mind, you would be able to solve your problem with a page reload by changing your app.py to look more like this:

from flask import Flask, render_template, Response, request, redirect, url_for
app = Flask(__name__)

@app.route("/")
def index():
    return render_template('index.html')

@app.route("/forward/", methods=['POST'])
def move_forward():
    #Moving forward code
    forward_message = "Moving Forward..."
    return render_template('index.html', forward_message=forward_message);

Then in your html, use this:

<form action="/forward/" method="post">
    <button name="forwardBtn" type="submit">Forward</button>
</form>

...To execute your moving forward code. And include this:

{{ forward_message }} 

... where you want the moving forward message to appear on your template.

This will cause your page to reload, which is inevitable without using AJAX and Javascript.

EDIT: As mentioned by Stephen Niedzielski in his comment, the issue seems to come from the 32-bit being of the JRE, which is de facto, looking for the 32-bit version of libXtst6. To install the required version of the library:

$ sudo apt-get install libxtst6:i386

Type:

$ sudo apt-get update
$ sudo apt-get install libxtst6

If this isn’t OK, type:

$ sudo updatedb
$ locate libXtst

it should return something like:

/usr/lib/x86_64-linux-gnu/libXtst.so.6       # Mine is OK
/usr/lib/x86_64-linux-gnu/libXtst.so.6.1.0

If you do not have libXtst.so.6 but do have libXtst.so.6.X.X create a symbolic link:

$ cd /usr/lib/x86_64-linux-gnu/
$ ln -s libXtst.so.6 libXtst.so.6.X.X

Hope this helps.

In summary: I would be careful as to what code you copy. It is possible you are copying code which happens to work, rather than well chosen code.

In intnumber, parseInt is used and in floatnumber valueOf is used why so?

There is no good reason I can see. It's an inconsistent use of the APIs as you suspect.

Java is case sensitive, and there isn't any Readline() method. Perhaps you mean readLine().

DataInputStream.readLine() is deprecated in favour of using BufferedReader.readLine();

However, for your case, I would use the Scanner class.

Scanner sc = new Scanner(System.in);
int intNum = sc.nextInt();
float floatNum = sc.nextFloat();

If you want to know what a class does I suggest you have a quick look at the Javadoc.

Easiest way would be to simply replace it with an empty string.

s = s.replace('papa', '')

Here is a Javascript version that returns a function that does the rescaling for predetermined source and destination ranges, minimizing the amount of computation that has to be done each time.

// This function returns a function bound to the 
// min/max source & target ranges given.
// oMin, oMax = source
// nMin, nMax = dest.
function makeRangeMapper(oMin, oMax, nMin, nMax ){
    //range check
    if (oMin == oMax){
        console.log("Warning: Zero input range");
        return undefined;
    };

    if (nMin == nMax){
        console.log("Warning: Zero output range");
        return undefined
    }

    //check reversed input range
    var reverseInput = false;
    let oldMin = Math.min( oMin, oMax );
    let oldMax = Math.max( oMin, oMax );
    if (oldMin != oMin){
        reverseInput = true;
    }

    //check reversed output range
    var reverseOutput = false;  
    let newMin = Math.min( nMin, nMax )
    let newMax = Math.max( nMin, nMax )
    if (newMin != nMin){
        reverseOutput = true;
    }

    // Hot-rod the most common case.
    if (!reverseInput && !reverseOutput) {
        let dNew = newMax-newMin;
        let dOld = oldMax-oldMin;
        return (x)=>{
            return ((x-oldMin)* dNew / dOld) + newMin;
        }
    }

    return (x)=>{
        let portion;
        if (reverseInput){
            portion = (oldMax-x)*(newMax-newMin)/(oldMax-oldMin);
        } else {
            portion = (x-oldMin)*(newMax-newMin)/(oldMax-oldMin)
        }
        let result;
        if (reverseOutput){
            result = newMax - portion;
        } else {
            result = portion + newMin;
        }

        return result;
    }   
}

Here is an example of using this function to scale 0-1 into -0x80000000, 0x7FFFFFFF

let normTo32Fn = makeRangeMapper(0, 1, -0x80000000, 0x7FFFFFFF);
let fs = normTo32Fn(0.5);
let fs2 = normTo32Fn(0);

a.insert(a.end(), b.begin(), b.end());

or

a.insert(std::end(a), std::begin(b), std::end(b));

The second variant is a more generically applicable solution, as b could also be an array. However, it requires C++11. If you want to work with user-defined types, use ADL:

using std::begin, std::end;
a.insert(end(a), begin(b), end(b));

First ensure that hlsearch is enabled by issuing the following command

:set hlsearch

You can also add this to your .vimrc file as set

set hlsearch

now when you use the quick search mechanism in command mode or a regular search command, all results will be highlighted. To move forward between results, press 'n' to move backwards press 'N'

In normal mode, to perform a quick search for the word under the cursor and to jump to the next occurrence in one command press '*', you can also search for the word under the cursor and move to the previous occurrence by pressing '#'

In normal mode, quick search can also be invoked with the

/searchterm<Enter>

to remove highlights on ocuurences use, I have bound this to a shortcut in my .vimrc

:nohl

None of these answers worked for me in all cases. I had to go directly to Google's Documentation https://developer.android.com/guide/topics/providers/document-provider.html on this topic and found this useful method:

private Bitmap getBitmapFromUri(Uri uri) throws IOException {
    ParcelFileDescriptor parcelFileDescriptor =
    getContentResolver().openFileDescriptor(uri, "r");
    FileDescriptor fileDescriptor = parcelFileDescriptor.getFileDescriptor();
    Bitmap image = BitmapFactory.decodeFileDescriptor(fileDescriptor);
    parcelFileDescriptor.close();
    return image;
}

You can use this bitmap to display it in an Image View.

[100 %]Solved. I had the same problem today. I checked my server space

df-h

I saw that server is out of space so i check which directory has most size by

sudo du -ch / | sort -h

I saw 12.2G /var/lib/jenkins so i entered this folder and cleared all the logs by

cd /var/libs/jenkins
rm *

and restart the jenkins it will work normal

sudo systemctl restart jenkins.service

Simple ruby script based on this answer: registry_cleaner.

You can run it on local machine:

./registry_cleaner.rb --host=https://registry.exmpl.com --repository=name --tags_count=4

And then on the registry machine remove blobs with /bin/registry garbage-collect /etc/docker/registry/config.yml.

You can execute parallel jobs in Powershell 2 using Background Jobs. Check out Start-Job and the other job cmdlets.

# Loop through the server list
Get-Content "ServerList.txt" | %{

  # Define what each job does
  $ScriptBlock = {
    param($pipelinePassIn) 
    Test-Path "\\$pipelinePassIn\c`$\Something"
    Start-Sleep 60
  }

  # Execute the jobs in parallel
  Start-Job $ScriptBlock -ArgumentList $_
}

Get-Job

# Wait for it all to complete
While (Get-Job -State "Running")
{
  Start-Sleep 10
}

# Getting the information back from the jobs
Get-Job | Receive-Job

You should place Scanner input = new Scanner (System.in); into the main method rather than creating the input object outside.

The real answer is: Because you cannot trust defer.

In concept, defer and async differ as follows:

async allows the script to be downloaded in the background without blocking. Then, the moment it finishes downloading, rendering is blocked and that script executes. Render resumes when the script has executed.

defer does the same thing, except claims to guarantee that scripts execute in the order they were specified on the page, and that they will be executed after the document has finished parsing. So, some scripts may finish downloading then sit and wait for scripts that downloaded later but appeared before them.

Unfortunately, due to what is really a standards cat fight, defer's definition varies spec to spec, and even in the most recent specs doesn't offer a useful guarantee. As answers here and this issue demonstrate, browsers implement defer differently:

• In certain situations some browsers have a bug that causes defer scripts to run out of order.
• Some browsers delay the DOMContentLoaded event until after the defer scripts have loaded, and some don't.
• Some browsers obey defer on <script> elements with inline code and without a src attribute, and some ignore it.

Fortunately the spec does at least specify that async overrides defer. So you can treat all scripts as async and get a wide swath of browser support like so:

<script defer async src="..."></script>

98% of browsers in use worldwide and 99% in the US will avoid blocking with this approach.

(If you need to wait until the document has finished parsing, listen to the event DOMContentLoaded event or use jQuery's handy .ready() function. You'd want to do this anyway to fall back gracefully on browsers that don't implement defer at all.)

Function MySheet()

  ' uncomment the below line to make it Volatile

Well, the "failure sending e-mail" should hopefully have a bit more detail. But there are a few things that could cause this.

1. Restrictions on the "From" address. If you are using different from addresses, some could be blocked by your SMTP service from being able to send.
2. Flood prevention on your SMTP service could be stopping the e-mails from going out.

Regardless if it is one of these or another error, you will want to look at the exception and inner exception to get a bit more detail.

Inside controller inject Request object. So if you want to access request body inside controller method 'foo' do the following:

public function foo(Request $request){
    $bodyContent = $request->getContent();
}

select id,    
NewsHeadline as news_headline,    
NewsText as news_text,    
state,    
CreatedDate as created_on    
from News    
WHERE CreatedDate>=DATEADD(DAY,-7,GETDATE())

If you don't mind using gVim, you can launch a single instance, so that when a new file is opened with it it's automatically opened in a new tab in the currently running instance.

to do this you can write: gVim --remote-tab-silent file

You could always make an alias to this command so that you don't have to type so many words. For example I use linux and bash and in my ~/.bashrc file I have:

alias g='gvim --remote-tab-silent'

so instead of doing $ mate file I do: $ g file

I noticed it myself, and found the files inside the backup folder. You can check where it is using Menu:Settings -> Preferences -> Backup. Note : My NPP installation is portable, and on Windows, so YMMV.

Actually, I was also having the same problem. I was running Ubuntu. Mine problem arises because I'd lost my public key of the Ubuntu. Even updating my system was not happening. It was giving GPG error. In that case, you can regain your key by using this command:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <key in GPG error>

After that npm works fine!

In my case solution works like this:

dialog_AssignTag.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

And Additionally in Xml of custom dialog:

Supporting ownership, maximum number of processes share lock and the maximum number of allowed processes/threads in critical section are three major factors that determine the name/type of the concurrent object with general name of lock. Since the value of these factors are binary (have two states), we can summarize them in a 3*8 truth-like table.

• X (Supports Ownership?): no(0) / yes(1)
• Y (#sharing processes): > 1 (8) / 1
• Z (#processes/threads in CA): > 1 (8) / 1

  X   Y   Z          Name
 --- --- --- ------------------------
  0   8   8   Semaphore              
  0   8   1   Binary Semaphore       
  0   1   8   SemaphoreSlim          
  0   1   1   Binary SemaphoreSlim(?)
  1   8   8   Recursive-Mutex(?)     
  1   8   1   Mutex                  
  1   1   8   N/A(?)                 
  1   1   1   Lock/Monitor           

Feel free to edit or expand this table, I've posted it as an ascii table to be editable:)

I would say that you should put styles that won't change into a regular style attribute, and conditional/scope styles into an ng-style attribute. Also, string keys are not necessary. For hyphen-delimited CSS keys, use camelcase.

<div ng-style="{backgroundColor: data.backgroundCol}" style="width:20px; height:20px; margin-top:10px; border:solid 1px black;"></div>

filter_input(INPUT_POST, 'checkbox_name', FILTER_DEFAULT, FILTER_FORCE_ARRAY)

The sender is the control that the action is for (say OnClick, it's the button).

The EventArgs are arguments that the implementor of this event may find useful. With OnClick it contains nothing good, but in some events, like say in a GridView 'SelectedIndexChanged', it will contain the new index, or some other useful data.

What Chris is saying is you can do this:

protected void someButton_Click (object sender, EventArgs ea)
{
    Button someButton = sender as Button;
    if(someButton != null)
    {
        someButton.Text = "I was clicked!";
    }
}

You can do this all from within your service executable in response to events fired from the InstallUtil process. Override the OnAfterInstall event to use a ServiceController class to start the service.

From the Java interface design FAQ by Philip Shaw:

Interface variables are static because Java interfaces cannot be instantiated in their own right; the value of the variable must be assigned in a static context in which no instance exists. The final modifier ensures the value assigned to the interface variable is a true constant that cannot be re-assigned by program code.

           for (var i=0; i<32; i++)
            {
              sGuid+=Math.floor(Math.random()*0xF).toString(0xF);
            }
           return sGuid;
         }

>>> dt64.tolist()
datetime.datetime(2012, 5, 1, 0, 0)

For DatetimeIndex, the tolist returns a list of datetime objects. For a single datetime64 object it returns a single datetime object.

Here's my go with comments in the code.

I'm just brushing up by biatch skills so forgive any blatant errors.

I tried to write an all in one solution as best I can with a little modification where the user requires it.

Some important notes: Just change the variable recursive to FALSE if you only want the root directories files and folders processed. Otherwise, it goes through all folders and files.

C&C most welcome...

Have just solved. Just two f. days of brutforce

For me the secret was in following:

1. I called POST /api/auth and see that cookies were successfully received.

2. Then calling GET /api/users/ with credentials: 'include' and got 401 unauth, because of no cookies were sent with the request.

The KEY is to set credentials: 'include' for the first /api/auth call too.

Simple solution for vertical align middle... for me it works like a charm

ul{display:table; text-align:center; margin:0 auto;}
li{display:inline-block; text-align:center;}
li.items_inside_li{display:inline-block; vertical-align:middle;}

This is WRONG:

import {
    Tabs,
    Tabpane
  } from 'iview'

This is CORRECT:

import Iview from "iview";
const { Tabs, Tabpane} = Iview;

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>

Use the constructor that takes a File and a boolean

FileOutputStream(File file, boolean append) 

and set the boolean to true. That way, the data you write will be appended to the end of the file, rather than overwriting what was already there.

had the problem with using the JDBC driver, so one just has to add the database (maybe redundantly depending on the tool you may use) after the host name in the URL, e.g. jdbc:postgres://<host(:port)>/<db-name>

Neither <iostream> nor <iostream.h> are standard C header files. Your code is meant to be C++, where <iostream> is a valid header. Use g++ (and a .cpp file extension) for C++ code.

Alternatively, this program uses mostly constructs that are available in C anyway. It's easy enough to convert the entire program to compile using a C compiler. Simply remove #include <iostream> and using namespace std;, and replace cout << endl; with putchar('\n');... I advise compiling using C99 (eg. gcc -std=c99)

A hex color code is #RRGGBB

RR, GG, BB are hex values ranging from 0-255

Let's call RR XY where X and Y are hex character 0-9A-F, A=10, F=15

The decimal value is X*16+Y

If RR = B7, the decimal for B is 11, so value is 11*16 + 7 = 183

public int[] getRGB(String rgb){
    int[] ret = new int[3];
    for(int i=0; i<3; i++){
        ret[i] = hexToInt(rgb.charAt(i*2), rgb.charAt(i*2+1));
    }
    return ret;
}

public int hexToInt(char a, char b){
    int x = a < 65 ? a-48 : a-55;
    int y = b < 65 ? b-48 : b-55;
    return x*16+y;
}

From C# specifications:

var f = 0f; // float
var d = 0d; // double
var m = 0m; // decimal (money)
var u = 0u; // unsigned int
var l = 0l; // long
var ul = 0ul; // unsigned long

Note that you can use an uppercase or lowercase notation.

Answers so far are absolutely correct; they delete all keys.

However, if you also want to delete all Lua scripts from the Redis instance, you should follow it by:

SCRIPT FLUSH

The OP asks two questions; this completes the second question (everything wiped).

A solution to ensure that images don't get cut when printed in a Web page is to have the following CSS rule:

@media print { 
  img { 
    max-width:100% !important;
  } 
}

None of those work for me.

.fa-volume-down {
    color: white;
    width: 50% !important;
    height: 50% !important;
    margin-top: 8%;
    margin-left: 7.5%;
    font-size: 1em;
    background-size: 120%;
}

Building off of Mulfix's answer, if you have Visual Studio Community 2015, try Add Reference... -> COM -> Type Libraries -> 'Microsoft Excel 15.0 Object Library'.

In Chrome, request with 'Content-Type:application/json' shows as Request PayedLoad and sends data as json object.

But request with 'Content-Type:application/x-www-form-urlencoded' shows Form Data and sends data as Key:Value Pair, so if you have array of object in one key it flats that key's value:

{ Id: 1, 
name:'john', 
phones:[{title:'home',number:111111,...},
        {title:'office',number:22222,...}]
}

sends

{ Id: 1, 
name:'john', 
phones:[object object]
phones:[object object]
}

now include bootstrap 4:

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.3/css/bootstrap.min.css');

and code should be like this:

<div class="row">
    <div class="col-lg-6 col-md-6" style="border:solid 1px red">elements 1</div>
    <div class="col-lg-6 col-md-6" style="border:solid 1px red">
         <div class="pull-lg-right pull-xl-right">
            elements 2
         </div>
    </div>
</div>

The Swift version from String to Data and back to String:

Xcode 10.1 • Swift 4.2.1

extension Data {
    var string: String? {
        return String(data: self, encoding: .utf8)
    }
}

extension StringProtocol {
    var data: Data {
        return Data(utf8)
    }
}

extension String {
    var base64Decoded: Data? {
        return Data(base64Encoded: self)
    }
}

Playground

let string = "Hello World"                                  // "Hello World"
let stringData = string.data                                // 11 bytes
let base64EncodedString = stringData.base64EncodedString()  // "SGVsbG8gV29ybGQ="
let stringFromData = stringData.string                      // "Hello World"

let base64String = "SGVsbG8gV29ybGQ="
if let data = base64String.base64Decoded {
    print(data)                                    //  11 bytes
    print(data.base64EncodedString())              // "SGVsbG8gV29ybGQ="
    print(data.string ?? "nil")                    // "Hello World"
}

let stringWithAccent = "Olá Mundo"                          // "Olá Mundo"
print(stringWithAccent.count)                               // "9"
let stringWithAccentData = stringWithAccent.data            // "10 bytes" note: an extra byte for the acute accent
let stringWithAccentFromData = stringWithAccentData.string  // "Olá Mundo\n"

You have to declare 2 different NSDateFormatters, the first to convert the string to a NSDate and the second to print the date in your format.
Try this code:

let dateFormatterGet = NSDateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd HH:mm:ss"

let dateFormatterPrint = NSDateFormatter()
dateFormatterPrint.dateFormat = "MMM dd,yyyy"

let date: NSDate? = dateFormatterGet.dateFromString("2016-02-29 12:24:26")
print(dateFormatterPrint.stringFromDate(date!))

Swift 3 and higher:

From Swift 3 NSDate class has been changed to Date and NSDateFormatter to DateFormatter.

let dateFormatterGet = DateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd HH:mm:ss"

let dateFormatterPrint = DateFormatter()
dateFormatterPrint.dateFormat = "MMM dd,yyyy"

if let date = dateFormatterGet.date(from: "2016-02-29 12:24:26") {
    print(dateFormatterPrint.string(from: date))
} else {
   print("There was an error decoding the string")
}

After many tries I found that you should use createNativeQuery And you can send parameters using # replacement

In my example

String UPDATE_lOGIN_TABLE_QUERY = "UPDATE OMFX.USER_LOGIN SET LOGOUT_TIME = SYSDATE WHERE LOGIN_ID = #loginId AND USER_ID = #userId";


Query query = em.createNativeQuery(logQuery);

            query.setParameter("userId", logDataDto.getUserId());
            query.setParameter("loginId", logDataDto.getLoginId());

            query.executeUpdate();

hg status will show you all the new files, and then you can just rm them.

Normally I want to get rid of ignored and unversioned files, so:

hg status -iu                          # to show 
hg status -iun0 | xargs -r0 rm         # to destroy

And then follow that with:

hg update -C -r xxxxx

which puts all the versioned files in the right state for revision xxxx

To follow the Stack Overflow tradition of telling you that you don't want to do this, I often find that this "Nuclear Option" has destroyed stuff I care about.

The right way to do it is to have a 'make clean' option in your build process, and maybe a 'make reallyclean' and 'make distclean' too.

Pretty easy in your controller you do:

public function create()
{
    $user = new User;

    $action = URL::route('user.store');

    return View::('viewname')->with(compact('user', 'action'));
}

public function edit($id)
{
    $user = User::find($id);

    $action = URL::route('user.update', ['id' => $id]);

    return View::('viewname')->with(compact('user', 'action'));
}

And you just have to use this way:

{{ Form::model($user, ['action' => $action]) }}

   {{ Form::input('email') }}
   {{ Form::input('first_name') }}

{{ Form::close() }}

yes there is on-mouseover in angular2 instead of ng-Mouseover like in angular 1.x so you have to write this :-

<div on-mouseover='over()' style="height:100px; width:100px; background:#e2e2e2">hello mouseover</div>

over(){
    console.log("Mouseover called");
  }

As @Gunter Suggested in comment there is alternate of on-mouseover we can use this too. Some people prefer the on- prefix alternative, known as the canonical form.

Update

HTML Code -

<div (mouseover)='over()' (mouseout)='out()' style="height:100px; width:100px; background:#e2e2e2">hello mouseover</div>

Controller/.TS Code -

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';

  over(){
    console.log("Mouseover called");
  }

  out(){
    console.log("Mouseout called");
  }
}

Working Example

Some other Mouse events can be used in Angular -

(mouseenter)="myMethod()"
(mousedown)="myMethod()"
(mouseup)="myMethod()"

It's not an array, it's an object of type stdClass.

You can access it like this:

echo $oResult->context;

docs

sample

This gives you last used row in a specified column.

Optionally you can specify worksheet, else it will takes active sheet.

Function shtRowCount(colm As Integer, Optional ws As Worksheet) As Long

    If ws Is Nothing Then Set ws = ActiveSheet

    If ws.Cells(Rows.Count, colm) <> "" Then
        shtRowCount = ws.Cells(Rows.Count, colm).Row
        Exit Function
    End If

    shtRowCount = ws.Cells(Rows.Count, colm).Row

    If shtRowCount = 1 Then
        If ws.Cells(1, colm) = "" Then
            shtRowCount = 0
        Else
            shtRowCount = 1
        End If
    End If

End Function

Sub test()

    Dim lgLastRow As Long
    lgLastRow = shtRowCount(2) 'Column B

End Sub

you can use $ (jquery) :

<div>
    <form role="form" class="form-horizontal ">        
        <div [ngClass]="{showElement:IsEditMode, hidden:!IsEditMode}">
            <div class="form-group">
                <label class="control-label col-md-1 col-sm-1" for="name">Name</label>
                <div class="col-md-7 col-sm-7">
                    <input id="txtname`enter code here`" type="text" [(ngModel)]="person.Name" class="form-control" />

                </div>
                <div class="col-md-2 col-sm-2">
                    <input type="button" value="Add" (click)="AddPerson()" class="btn btn-primary" />
                </div>
            </div>
        </div>
        <div [ngClass]="{showElement:!IsEditMode, hidden:IsEditMode}">
            <div class="form-group">
                <label class="control-label col-md-1 col-sm-1" for="name">Person</label>
                <div class="col-md-7 col-sm-7">
                    <select [(ngModel)]="SelectedPerson.Id"  (change)="PersonSelected($event.target.value)" class="form-control">
                        <option *ngFor="#item of PeopleList" value="{{item.Id}}">{{item.Name}}</option>
                    </select>
                </div>
            </div>
        </div>        
    </form>
</div>

then in ts :

    declare var $: any;

    @Component({
      selector: 'app-my-comp',
      templateUrl: './my-comp.component.html',
      styleUrls: ['./my-comp.component.css']
    })
    export class MyComponent  {

    @ViewChild('loadedComponent', { read: ElementRef, static: true }) loadedComponent: ElementRef<HTMLElement>;

    setFocus() {
    const elem = this.loadedComponent.nativeElement.querySelector('#txtname');
          $(elem).focus();
    }
    }

Java 8 is in the market after almost 2 decades, following is the way to iterate org.json.JSONArray with java8 Stream API.

import org.json.JSONArray;
import org.json.JSONObject;

@Test
public void access_org_JsonArray() {
    //Given: array
    JSONArray jsonArray = new JSONArray(Arrays.asList(new JSONObject(
                    new HashMap() {{
                        put("a", 100);
                        put("b", 200);
                    }}
            ),
            new JSONObject(
                    new HashMap() {{
                        put("a", 300);
                        put("b", 400);
                    }}
            )));

    //Then: convert to List<JSONObject>
    List<JSONObject> jsonItems = IntStream.range(0, jsonArray.length())
            .mapToObj(index -> (JSONObject) jsonArray.get(index))
            .collect(Collectors.toList());

    // you can access the array elements now
    jsonItems.forEach(arrayElement -> System.out.println(arrayElement.get("a")));
    // prints 100, 300
}

If the iteration is only one time, (no need to .collect)

    IntStream.range(0, jsonArray.length())
            .mapToObj(index -> (JSONObject) jsonArray.get(index))
            .forEach(item -> {
               System.out.println(item);
            });

The Date object handles 8601 as it's first parameter:

var d = new Date("2014-04-07T13:58:10.104Z");_x000D_
console.log(d.toString());

The latter strings shouldn't start with a slash. If they start with a slash, then they're considered an "absolute path" and everything before them is discarded.

Quoting the Python docs for os.path.join:

If a component is an absolute path, all previous components are thrown away and joining continues from the absolute path component.

Note on Windows, the behaviour in relation to drive letters, which seems to have changed compared to earlier Python versions:

On Windows, the drive letter is not reset when an absolute path component (e.g., r'\foo') is encountered. If a component contains a drive letter, all previous components are thrown away and the drive letter is reset. Note that since there is a current directory for each drive, os.path.join("c:", "foo") represents a path relative to the current directory on drive C: (c:foo), not c:\foo.

As of swift 3.0 .normal state has been removed.you can use following to apply normal state.

myButton.setTitle("myTitle", for: [])

Probably late to the party. You can use Jackson and convert it into a Properties object. This is suited for Nested classes and if you want the key in the for a.b.c=value.

JavaPropsMapper mapper = new JavaPropsMapper();
Properties properties = mapper.writeValueAsProperties(sct);
Map<Object, Object> map = properties;

if you want some suffix, then just do

SerializationConfig config = mapper.getSerializationConfig()
                .withRootName("suffix");
mapper.setConfig(config);

need to add this dependency

<dependency>
  <groupId>com.fasterxml.jackson.dataformat</groupId>
  <artifactId>jackson-dataformat-properties</artifactId>
</dependency>

Jut use

ArrayAdapter<String> adaptername = new ArrayAdapter<String>(this,
            android.R.layout.simple_dropdown_item_1line, your array list);

The latter (<>), because the meaning of the former isn't clear unless you have a perfect understanding of the order of operations as it applies to the Not and = operators: a subtlety which is easy to miss.

You could just try using return false (return false overrides default behaviour on every DOM element) like that :

myform.onsubmit = function ()
{ 
  // do what you want
  return false
}

and then submit your form using myform.submit()

or alternatively :

mybutton.onclick = function () 
{
   // do what you want
   return false
}

Also, if you use type="button" your form will not be submitted.

It means display width

Whether you use tinyint(1) or tinyint(2), it does not make any difference.

I always use tinyint(1) and int(11), I used several mysql clients (navicat, sequel pro).

It does not mean anything AT ALL! I ran a test, all above clients or even the command-line client seems to ignore this.

But, display width is most important if you are using ZEROFILL option, for example your table has following 2 columns:

A tinyint(2) zerofill

B tinyint(4) zerofill

both columns has the value of 1, output for column A would be 01 and 0001 for B, as seen in screenshot below :)

To further illustrate the common strategy of frequent restarts, we can use littler which allows us to run simple expressions directly from the command-line. Here is an example I sometimes use to time different BLAS for a simple crossprod.

 r -e'N<-3*10^3; M<-matrix(rnorm(N*N),ncol=N); print(system.time(crossprod(M)))'

Likewise,

 r -lMatrix -e'example(spMatrix)'

loads the Matrix package (via the --packages | -l switch) and runs the examples of the spMatrix function. As r always starts 'fresh', this method is also a good test during package development.

Last but not least r also work great for automated batch mode in scripts using the '#!/usr/bin/r' shebang-header. Rscript is an alternative where littler is unavailable (e.g. on Windows).

The accepted answer is correct but I'd like to add my two cents. I've run into a problem where I had a project A that had a project B as a dependency. Both projects use slf4j but project B uses log4j while project A uses logback. Project B uses slf4j 1.6.1, while project A uses slf4j 1.7.5 (due to the already included logback 1.2.3 dependency).

The problem: Project A couldn't find a function that exists on slf4j 1.7.5, after checking eclipe's dependency hierarchy tab I found out that during build it was using slf4j 1.6.1 from project B, instead of using logback's slf4j 1.7.5.

I solved the issue by changing the order of the dependencies on project A pom, when I moved project B entry below the logback entry then maven started to build the project using slf4j 1.7.5.

Edit: Adding the slf4j 1.7.5 dependency before Project B dependency worked too.

Firstly name isn't a valid attribute of an option element. Instead you could use a data parameter, like this:

<option value="foo" data-name="bar">Foo Bar</option>

The main issue you have is that the JS is looking at the name attribute of the select element, not the chosen option. Try this:

$('#band_type_choices').on('change', function() {         
    $('.checkboxlist').hide();
    $('#checkboxlist_' + $('option:selected', this).data("name")).css("display", "block");
});

Note the option:selected selector within the context of the select which raised the change event.

It seems a bit strange to totally forbid the use of something like a for loop.

There's an interesting article here that covers a lot of the performance differences between the two loops.

I would say personally I find foreach a bit more readable over for loops but you should use the best for the job at hand and not have to write extra long code to include a foreach loop if a for loop is more appropriate.

To avoid repeating what have been said multiple times, I am showing an alternative for those that need a cryptographically stronger pseudo-random number generator by using the SecureRandom class, which extends the class Random. From source one can read:

This class provides a cryptographically strong random number generator (RNG). A cryptographically strong random number minimally complies with the statistical random number generator tests specified in FIPS 140-2, Security Requirements for Cryptographic Modules, section 4.9.1. Additionally, SecureRandom must produce non-deterministic output. Therefore any seed material passed to a SecureRandom object must be unpredictable, and all SecureRandom output sequences must be cryptographically strong, as described in RFC 1750: Randomness Recommendations for Security.

A caller obtains a SecureRandom instance via the no-argument constructor or one of the getInstance methods:

  SecureRandom random = new SecureRandom();  

Many SecureRandom implementations are in the form of a pseudo-random number generator (PRNG), which means they use a deterministic algorithm to produce a pseudo-random sequence from a true random seed. Other implementations may produce true random numbers, and yet others may use a combination of both techniques.

To generate a random number between a min and max values inclusive:

public static int generate(SecureRandom secureRandom, int min, int max) {
        return min + secureRandom.nextInt((max - min) + 1);
}

for a given a min (inclusive) and max (exclusive) values:

return min + secureRandom.nextInt((max - min));

A running code example:

public class Main {

    public static int generate(SecureRandom secureRandom, int min, int max) {
        return min + secureRandom.nextInt((max - min) + 1);
    }

    public static void main(String[] arg) {
        SecureRandom random = new SecureRandom();
        System.out.println(generate(random, 0, 2 ));
    }
}

Source such as stackoverflow, baeldung, geeksforgeeks provide comparisons between Random and SecureRandom classes.

From baeldung one can read:

The most common way of using SecureRandom is to generate int, long, float, double or boolean values:

int randomInt = secureRandom.nextInt();
long randomLong = secureRandom.nextLong();
float randomFloat = secureRandom.nextFloat();
double randomDouble = secureRandom.nextDouble();
boolean randomBoolean = secureRandom.nextBoolean();

For generating int values we can pass an upper bound as a parameter:

int randomInt = secureRandom.nextInt(upperBound);

In addition, we can generate a stream of values for int, double and long:

IntStream randomIntStream = secureRandom.ints();
LongStream randomLongStream = secureRandom.longs();
DoubleStream randomDoubleStream = secureRandom.doubles();

For all streams we can explicitly set the stream size:

IntStream intStream = secureRandom.ints(streamSize);

This class offers several other options (e.g., choosing the underlying random number generator) that are out of the scope of this question.

If none of the solutions work for you, the handling the post-autoload-dump event returned with error code 1 error can also be caused by using Composer 2 instead of Composer 1. That can happen when you run the install command manually in something like a Dockerfile, and it installs newest. Just modify your command to install the last 1.x.x stable version with the --1 option:

curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer --1

Or, specify a certain version with --version=x.x.x:

curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer --version=1.10.17

It might be good to also delete your vendor directory and composer.lock file so that nothing stale interferes with the version downgrade, before calling composer install as usual.

It really depends on how it is coded but something like this may work:

driver.findElement(By.id("datepicker")).click(); //click field
driver.findElement(By.linkText("Next")).click(); //click next month
driver.findElement(By.linkText("28")).click(); //click day

Seems like var ctx = $('#myChart'); is returning a list of elements. You would need to reference the first by using ctx[0]. Also height is a property, not a function.

I did it this way in my code:

var ctx = document.getElementById("myChart");
ctx.height = 500;

I have updated the code to make it works for me

$.xhrPool = [];
$.xhrPool.abortAll = function() {
    $(this).each(function(idx, jqXHR) {
        jqXHR.abort();
    });
    $(this).each(function(idx, jqXHR) {
        var index = $.inArray(jqXHR, $.xhrPool);
        if (index > -1) {
            $.xhrPool.splice(index, 1);
        }
    });
};

$.ajaxSetup({
    beforeSend: function(jqXHR) {
        $.xhrPool.push(jqXHR);
    },
    complete: function(jqXHR) {
        var index = $.inArray(jqXHR, $.xhrPool);
        if (index > -1) {
            $.xhrPool.splice(index, 1);
        }
    }
});

You are missing a semicolon at the end of your 'struct' definition.

For those who Googled "disable a button" but may have more nuanced use cases:

Disable with visual effect: As others have said, this will prevent the button from being pressed and the system will automatically make it look disabled:

yourButton.isEnabled = false 

Disable without visual effect: Are you using a button in a case where it should look normal but not behave likes button by reacting to touches? Try this!

yourButton.userInteractionEnabled = false

Hide without disabling: This approach hides the button without disabling it (invisible but can still be tapped):

 yourButton.alpha = 0.0

Remove: This will remove the view entirely:

 yourButton.removeFromSuperView()

Tap something behind a button: Have two buttons stacked and you want the top button to temporarily act like it's not there? If you won't need the top button again, remove it. If you will need it again, try condensing its height or width to 0!

There are two types of string in python: the traditional str type and the newer unicode type. If you type a string literal without the u in front you get the old str type which stores 8-bit characters, and with the u in front you get the newer unicode type that can store any Unicode character.

The r doesn't change the type at all, it just changes how the string literal is interpreted. Without the r, backslashes are treated as escape characters. With the r, backslashes are treated as literal. Either way, the type is the same.

ur is of course a Unicode string where backslashes are literal backslashes, not part of escape codes.

You can try to convert a Unicode string to an old string using the str() function, but if there are any unicode characters that cannot be represented in the old string, you will get an exception. You could replace them with question marks first if you wish, but of course this would cause those characters to be unreadable. It is not recommended to use the str type if you want to correctly handle unicode characters.

You can iterate over keys and get values by keys:

for key in dict.iterkeys():
    print key, dict[key]

You can iterate over keys and corresponding values:

for key, value in dict.iteritems():
    print key, value

You can use enumerate if you want indexes (remember that dictionaries don't have an order):

>>> for index, key in enumerate(dict):
...     print index, key
... 
0 orange
1 mango
2 apple
>>> 

Mr. Curious was curious about this as well. In addition to the #>> '{}' operator, in 9.6+ one can get the value of a jsonb string with the ->> operator:

select to_jsonb('Some "text"'::TEXT)->>0;
  ?column?
-------------
 Some "text"
(1 row)

If one has a json value, then the solution is to cast into jsonb first:

select to_json('Some "text"'::TEXT)::jsonb->>0;
  ?column?
-------------
 Some "text"
(1 row)

This will completely disable scrolling:

$('html, body').css({
    overflow: 'hidden',
    height: '100%'
});

To restore:

$('html, body').css({
    overflow: 'auto',
    height: 'auto'
});

Tested it on Firefox and Chrome.

I found a caveat that no one so far has mentioned. I don't know if it will come up often in practical situations, but here it is for the sake of completeness.

Usually, calculating a number modulo infinity returns itself as a float, but a fraction modulo infinity returns nan (not a number). Here is an example:

>>> from fractions import Fraction
>>> from math import inf
>>> 3 % inf
3.0
>>> 3.5 % inf
3.5
>>> Fraction('1/3') % inf
nan

I filed an issue on the Python bug tracker. It can be seen at https://bugs.python.org/issue32968.

Write a function lensort to sort a list of strings based on length.

def lensort(a):
    n = len(a)
    for i in range(n):
        for j in range(i+1,n):
            if len(a[i]) > len(a[j]):
                temp = a[i]
                a[i] = a[j]
                a[j] = temp
    return a
print lensort(["hello","bye","good"])

You can set aliases for the columns that you are selecting:

I found the above answers quite useful but not really general purpose, they all need some other major build system like Ant or Maven.

I wanted to generate a report in a simple one-shot command that I could call from anything (from a build, test or just myself) so I have created junit2html which can be found here: https://github.com/inorton/junit2html

You can install it by doing:

pip install junit2html

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

Simple way to compare time is :

$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
     // your code
}

monthly_mean.plot(y='A')

Uses index as x-axis by default.

Here is the example:

SQL> set define off;
SQL> select * from dual where dummy='&var';

no rows selected

SQL> set define on
SQL> /
Enter value for var: X
old   1: select * from dual where dummy='&var'
new   1: select * from dual where dummy='X'

D
-
X

With set define off, it took a row with &var value, prompted a user to enter a value for it and replaced &var with the entered value (in this case, X).

Attach an event listener to the form using .addEventListener() and then call the .preventDefault() method on event:

const element = document.querySelector('form');_x000D_
element.addEventListener('submit', event => {_x000D_
  event.preventDefault();_x000D_
  // actual logic, e.g. validate the form_x000D_
  console.log('Form submission cancelled.');_x000D_
});

<form>_x000D_
  <button type="submit">Submit</button>_x000D_
</form>

I think it's a better solution than defining a submit event handler inline with the onsubmit attribute because it separates webpage logic and structure. It's much easier to maintain a project where logic is separated from HTML. See: Unobtrusive JavaScript.

Using the .onsubmit property of the form DOM object is not a good idea because it prevents you from attaching multiple submit callbacks to one element. See addEventListener vs onclick .

Use empty (it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"

If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"

Update: as per the comments, the Map turns out to actually be a List (please work on your naming conventions). To check if a List contains an item the "normal" EL way, use JSTL fn:contains (although not explicitly documented, it works for List as well).

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"

A CLASSPATH entry is either a directory at the head of a package hierarchy of .class files, or a .jar file. If you're expecting ./lib to include all the .jar files in that directory, it won't. You have to name them explicitly.

If you are only comparing objects of the same type or further down the inheritance chain, why not specify the parameter as your base type, rather than object ?

Also do null checks on the parameter as well.

Furthermore I'd make use of 'var' just to make the code more readable (if its c#3 code)

Also, if the object has reference types as properties then you are just calling ToString() on them which doesn't really compare values. If ToString isn't overwridden then its just going to return the type name as a string which could return false-positives.

To complete the picture, since -Werror might considered too "invasive",
for gcc (and llvm) a more precise solution is to transform just this warning in an error, using the option:

-Werror=implicit-function-declaration

See Make one gcc warning an error?

Regarding general use of -Werror: Of course, having warningless code is recommendable, but in some stage of development it might slow down the prototyping.

You may define the following function

clc <- function() cat(rep("\n", 50))

which you can then call as clc().

after you add the user for testing. the user should get an email. open that email by your iOS device, then click "Start testing" it will bring you to testFlight to download the app directly. If you open that email via computer, and then click "Start testing" it will show you another page which have the instruction of how to install the app. and that invitation code is on the last line. those All upper case letters is the code.

You have to enable Type Name Handling and pass that to the (de)serializer as a settings parameter.

Base object1 = new Base() { Name = "Object1" };
Derived object2 = new Derived() { Something = "Some other thing" };
List<Base> inheritanceList = new List<Base>() { object1, object2 };

JsonSerializerSettings settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
string Serialized = JsonConvert.SerializeObject(inheritanceList, settings);
List<Base> deserializedList = JsonConvert.DeserializeObject<List<Base>>(Serialized, settings);

This will result in correct deserialization of derived classes. A drawback to it is that it will name all the objects you are using, as such it will name the list you are putting the objects in.

var src = "data:image/jpeg;base64,";

I've always used .place() for my tkinter widgets. place syntax

You can specify the size of it just by changing the keyword arguments!

Of course, you will have to call .place() again if you want to change it.

Use the pandas to_datetime function to parse the column as DateTime. Also, by using infer_datetime_format=True, it will automatically detect the format and convert the mentioned column to DateTime.

import pandas as pd
raw_data['Mycol'] =  pd.to_datetime(raw_data['Mycol'], infer_datetime_format=True)

    For Each _property As PropertyInfo In properties
        Console.WriteLine("Name: " + _property.Name + ", Value: " + _property.GetValue(Someobject, Nothing))

Yes & No, but delegate pattern in Java could be thought of this way. This video tutorial is about data exchange between activity - fragments, and it has great essence of delegate sorta pattern using interfaces.

There is built in functionality for this using the JavaScriptSerializer Class:

var json = JavaScriptSerializer.Serialize(data);

Chr(10) is the Line Feed character and Chr(13) is the Carriage Return character.

You probably won't notice a difference if you use only one or the other, but you might find yourself in a situation where the output doesn't show properly with only one or the other. So it's safer to include both.

Historically, Line Feed would move down a line but not return to column 1:

This  
    is  
        a  
            test.

Similarly Carriage Return would return to column 1 but not move down a line:

This  
is  
a  
test.

Paste this into a text editor and then choose to "show all characters", and you'll see both characters present at the end of each line. Better safe than sorry.

You can use the "Except" extension method (see http://msdn.microsoft.com/en-us/library/bb337804.aspx)

In your code

var difference = people.Except(exclusions);

All you can do is to call equals() method on empty String literal and pass the object you are testing as shown below :

 String nullString = null;
 String empty = new String();
 boolean test = "".equals(empty); // true 
 System.out.println(test); 
 boolean check = "".equals(nullString); // false 
 System.out.println(check);

You're storing all (sub-) files and folder recursively in a list, but with your current code you store the parent folder before you store the children. And so you try to delete the folder before it is empty. Try this code:

   if(tempFile.isDirectory()) {
        // children first
        fetchCompleteList(filesList, folderList, tempFile.getAbsolutePath());
        // parent folder last
        folderList.add(tempFile.getAbsolutePath());
   }

//do the edit in your javascript

$('.signinform').submit(function() { 
   $(this).ajaxSubmit({ 
       type : "POST",
       //set the data type
       dataType:'json',
       url: 'index.php/user/signin', // target element(s) to be updated with server response 
       cache : false,
       //check this in Firefox browser
       success : function(response){ console.log(response); alert(response)},
       error: onFailRegistered
   });        
   return false; 
}); 


//controller function

public function signin() {
    $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);    

   //add the header here
    header('Content-Type: application/json');
    echo json_encode( $arr );
}

You can repaint and / or requery:

On the close event of form B:

Forms!FormA.Requery

Is this what you mean?

I think you're confusing server code with client code.

JavaScript runs on the client after it has received data from the server (like a webpage).

PHP runs on the server before it sends the data.

So there are two ways with interacting with JavaScript with php.

Like above, you can generate javascript with php in the same fashion you generate HTML with php.

Or you can use an AJAX request from javascript to interact with the server. The server can respond with data and the javascript can receive that and do something with it.

I'd recommend going back to the basics and studying how HTTP works in the server-client relationship. Then study the concept of server side languages and client side languages.

Then take a tutorial with ajax, and you will start getting the concept.

Good luck, google is your friend.

Ecmascript 6 includes "destructuring assignments" (as kangax mentioned) so in all browsers (not just Firefox) you'll be able to capture an array of values without having to make a named array or object for the sole purpose of capturing them.

//so to capture from this function
function myfunction()
{
 var n=0;var s=1;var w=2;var e=3;
 return [n,s,w,e];
}

//instead of having to make a named array or object like this
var IexistJusttoCapture = new Array();
IexistJusttoCapture = myfunction();
north=IexistJusttoCapture[0];
south=IexistJusttoCapture[1];
west=IexistJusttoCapture[2];
east=IexistJusttoCapture[3];

//you'll be able to just do this
[north, south, west, east] = myfunction(); 

You can try it out in Firefox already!

What will be cleaner and easier to maintain?

All things being equal, probably JavaFX - the API is much more consistent across components. However, this depends much more on how the code is written rather than what library is used to write it.

And what will be faster to build from scratch?

Highly dependent on what you're building. Swing has more components around for it (3rd party as well as built in) and not all of them have made their way to the newer JavaFX platform yet, so there may be a certain amount of re-inventing the wheel if you need something a bit custom. On the other hand, if you want to do transitions / animations / video stuff then this is orders of magnitude easier in FX.

One other thing to bear in mind is (perhaps) look and feel. If you absolutely must have the default system look and feel, then JavaFX (at present) can't provide this. Not a big must have for me (I prefer the default FX look anyway) but I'm aware some policies mandate a restriction to system styles.

Personally, I see JavaFX as the "up and coming" UI library that's not quite there yet (but more than usable), and Swing as the borderline-legacy UI library that's fully featured and supported for the moment, but probably won't be so much in the years to come (and therefore chances are FX will overtake it at some point.)

Explicitly filling in the ContentDisposition fields did the trick.

if (attachmentFilename != null)
{
    Attachment attachment = new Attachment(attachmentFilename, MediaTypeNames.Application.Octet);
    ContentDisposition disposition = attachment.ContentDisposition;
    disposition.CreationDate = File.GetCreationTime(attachmentFilename);
    disposition.ModificationDate = File.GetLastWriteTime(attachmentFilename);
    disposition.ReadDate = File.GetLastAccessTime(attachmentFilename);
    disposition.FileName = Path.GetFileName(attachmentFilename);
    disposition.Size = new FileInfo(attachmentFilename).Length;
    disposition.DispositionType = DispositionTypeNames.Attachment;
    message.Attachments.Add(attachment);                
}

BTW, in case of Gmail, you may have some exceptions about ssl secure or even port!

smtpClient.EnableSsl = true;
smtpClient.Port = 587;

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

Warning, you want 'none' (the string). None means the default color instead.

Using useEffect hook:

useEffect(() => {
  const ourRequest = Axios.CancelToken.source() // <-- 1st step

  const fetchPost = async () => {
    try {
      const response = await Axios.get(`endpointURL`, {
        cancelToken: ourRequest.token, // <-- 2nd step
      })
      console.log(response.data)
      setPost(response.data)
      setIsLoading(false)
    } catch (err) {
      console.log('There was a problem or request was cancelled.')
    }
  }
  fetchPost()

  return () => {
    ourRequest.cancel() // <-- 3rd step
  }
}, [])

Note: For POST request, pass cancelToken as 3rd argument

Axios.post(`endpointURL`, {data}, {
 cancelToken: ourRequest.token, // 2nd step
})

How about this?

=IF(ISERROR(MATCH(A1,B:B, 0)), "No Match", INDIRECT(ADDRESS(MATCH(A1,B:B, 0), 3)))

The "3" at the end means for column C.

The current (as of version 0.20) method for changing column names after a groupby operation is to chain the rename method. See this deprecation note in the documentation for more detail.

Deprecated Answer as of pandas version 0.20

This is the first result in google and although the top answer works it does not really answer the question. There is a better answer here and a long discussion on github about the full functionality of passing dictionaries to the agg method.

These answers unfortunately do not exist in the documentation but the general format for grouping, aggregating and then renaming columns uses a dictionary of dictionaries. The keys to the outer dictionary are column names that are to be aggregated. The inner dictionaries have keys that the new column names with values as the aggregating function.

Before we get there, let's create a four column DataFrame.

df = pd.DataFrame({'A' : list('wwwwxxxx'), 
                   'B':list('yyzzyyzz'), 
                   'C':np.random.rand(8), 
                   'D':np.random.rand(8)})

   A  B         C         D
0  w  y  0.643784  0.828486
1  w  y  0.308682  0.994078
2  w  z  0.518000  0.725663
3  w  z  0.486656  0.259547
4  x  y  0.089913  0.238452
5  x  y  0.688177  0.753107
6  x  z  0.955035  0.462677
7  x  z  0.892066  0.368850

Let's say we want to group by columns A, B and aggregate column C with mean and median and aggregate column D with max. The following code would do this.

df.groupby(['A', 'B']).agg({'C':['mean', 'median'], 'D':'max'})

            D         C          
          max      mean    median
A B                              
w y  0.994078  0.476233  0.476233
  z  0.725663  0.502328  0.502328
x y  0.753107  0.389045  0.389045
  z  0.462677  0.923551  0.923551

This returns a DataFrame with a hierarchical index. The original question asked about renaming the columns in the same step. This is possible using a dictionary of dictionaries:

df.groupby(['A', 'B']).agg({'C':{'C_mean': 'mean', 'C_median': 'median'}, 
                            'D':{'D_max': 'max'}})

            D         C          
        D_max    C_mean  C_median
A B                              
w y  0.994078  0.476233  0.476233
  z  0.725663  0.502328  0.502328
x y  0.753107  0.389045  0.389045
  z  0.462677  0.923551  0.923551

This renames the columns all in one go but still leaves the hierarchical index which the top level can be dropped with df.columns = df.columns.droplevel(0).

For more advanced GET/POST requests, you can install the CURL library (http://us3.php.net/curl):

$ch = curl_init("REMOTE XML FILE URL GOES HERE"); // such as http://example.com/example.xml
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
$data = curl_exec($ch);
curl_close($ch);

I found a solution wich is to do:

<span class="visible-sm"> your code without col </span>
<span class="visible-xs"> your code with col </span>

It's not very optimized but it works. Did you find something better? It really miss a class like col-sm-0 to apply colons just to the xs size...

I usualy use a multi-culture function to parse user input, mostly because if someone is used to the numpad and is using a culture that use a comma as the decimal separator, that person will use the point of the numpad instead of a comma.

public static double GetDouble(string value, double defaultValue)
{
    double result;

    //Try parsing in the current culture
    if (!double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.CurrentCulture, out result) &&
        //Then try in US english
        !double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.GetCultureInfo("en-US"), out result) &&
        //Then in neutral language
        !double.TryParse(value, System.Globalization.NumberStyles.Any, CultureInfo.InvariantCulture, out result))
    {
        result = defaultValue;
    }

    return result;
}

Beware though, @nikie comments are true. To my defense, I use this function in a controlled environment where I know that the culture can either be en-US, en-CA or fr-CA. I use this function because in French, we use the comma as a decimal separator, but anybody who ever worked in finance will always use the decimal separator on the numpad, but this is a point, not a comma. So even in the fr-CA culture, I need to parse number that will have a point as the decimal separator.

You can easily create your own extension method on IEnumerable or IQueryable:

public static IOrderedEnumerable<TSource> OrderByWithDirection<TSource,TKey>
    (this IEnumerable<TSource> source,
     Func<TSource, TKey> keySelector,
     bool descending)
{
    return descending ? source.OrderByDescending(keySelector)
                      : source.OrderBy(keySelector);
}

public static IOrderedQueryable<TSource> OrderByWithDirection<TSource,TKey>
    (this IQueryable<TSource> source,
     Expression<Func<TSource, TKey>> keySelector,
     bool descending)
{
    return descending ? source.OrderByDescending(keySelector)
                      : source.OrderBy(keySelector);
}

Yes, you lose the ability to use a query expression here - but frankly I don't think you're actually benefiting from a query expression anyway in this case. Query expressions are great for complex things, but if you're only doing a single operation it's simpler to just put that one operation:

var query = dataList.OrderByWithDirection(x => x.Property, direction);

Random random=new Random();
int randomNumber=(random.nextInt(65536)-32768);

git log + git branch will find it for you:

% git log --all -- somefile

    added somefile


% git branch -a --contains 55d2069
  otherbranch

Supports globbing, too:

% git log --all -- '**/my_file.png'

The single quotes are necessary (at least if using the Bash shell) so the shell passes the glob pattern to git unchanged, instead of expanding it (just like with Unix find).

You should try this

 SELECT t1.*,t2.* FROM t1,t2
