It seems that IDLE changes its current working dir to location of the script that is executed, while when running the script using cmd doesn't do that and it leaves CWD as it is.

To change current working dir to the one containing your script you can use:

import os
os.chdir(os.path.dirname(__file__))
print(os.getcwd())

The __file__ variable is available only if you execute script from file, and it contains path to the file. More on it here: Python __file__ attribute absolute or relative?

Forming a XML file

XmlTextWriter xmlw = new XmlTextWriter(@"C:\WINDOWS\Temp\exm.xml",System.Text.Encoding.UTF8);
xmlw.WriteStartDocument();            
xmlw.WriteStartElement("examtimes");
xmlw.WriteStartElement("Starttime");
xmlw.WriteString(DateTime.Now.AddHours(0).ToString());
xmlw.WriteEndElement();
xmlw.WriteStartElement("Changetime");
xmlw.WriteString(DateTime.Now.AddHours(0).ToString());
xmlw.WriteEndElement();
xmlw.WriteStartElement("Endtime");
xmlw.WriteString(DateTime.Now.AddHours(1).ToString());
xmlw.WriteEndElement();
xmlw.WriteEndElement();
xmlw.WriteEndDocument();  
xmlw.Close();           

To edit the Xml nodes use the below code

XmlDocument doc = new XmlDocument(); 
doc.Load(@"C:\WINDOWS\Temp\exm.xml"); 
XmlNode root = doc.DocumentElement["Starttime"]; 
root.FirstChild.InnerText = "First"; 
XmlNode root1 = doc.DocumentElement["Changetime"]; 
root1.FirstChild.InnerText = "Second"; 
doc.Save(@"C:\WINDOWS\Temp\exm.xml"); 

Try this. It's C# code.

For those of you who are setting up MSYS Git on Windows using PuTTY via the standard command prompt, the way to add a host to PuTTY's cache is to run

> plink.exe <host>

For example:

> plink.exe codebasehq.com

The server's host key is not cached in the registry. You
have no guarantee that the server is the computer you
think it is.
The server's rsa2 key fingerprint is:
ssh-rsa 2048 2e:db:b6:22:f7:bd:48:f6:da:72:bf:59:d7:75:d7:4e
If you trust this host, enter "y" to add the key to
PuTTY's cache and carry on connecting.
If you want to carry on connecting just once, without
adding the key to the cache, enter "n".
If you do not trust this host, press Return to abandon the
connection.
Store key in cache? (y/n)

Just answer y, and then Ctrl+C the rest.

Do check the fingerprint though. This warning is there for a good reason. Fingerprints for some git services (please edit to add more):

• GitHub: 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48
• Bitbucket: 97:8c:1b:f2:6f:14:6b:5c:3b:ec:aa:46:46:74:7c:40
• Gitorious: 7e:af:8d:ec:f0:39:5e:ba:52:16:ce:19:fa:d4:b8:7d

Yes, that is supported.

Check the documentation provided here for the supported keywords inside method names.

You can just define the method in the repository interface without using the @Query annotation and writing your custom query. In your case it would be as followed:

List<Inventory> findByIdIn(List<Long> ids);

I assume that you have the Inventory entity and the InventoryRepository interface. The code in your case should look like this:

The Entity

@Entity
public class Inventory implements Serializable {

  private static final long serialVersionUID = 1L;

  private Long id;

  // other fields
  // getters/setters

}

The Repository

@Repository
@Transactional
public interface InventoryRepository extends PagingAndSortingRepository<Inventory, Long> {

  List<Inventory> findByIdIn(List<Long> ids);

}

maybe you forget to add parameter dataType:'json' in your $.ajax

$.ajax({
   type: "POST",
   dataType: "json",
   url: url,
   data: { get_member: id },
   success: function( response ) 
   { 
     //some action here
   },
   error: function( error )
   {
     alert( error );
   }
});

New simpler and recommended method: Apple recommends using URLs for filehandling and the other solutions here seem deprecated (see comments below). The following is the new simple way of reading and writing with URL's (don't forget to handle the possible URL errors):

Swift 5+, 4 and 3.1

import Foundation  // Needed for those pasting into Playground

let fileName = "Test"
let dir = try? FileManager.default.url(for: .documentDirectory, 
      in: .userDomainMask, appropriateFor: nil, create: true)

// If the directory was found, we write a file to it and read it back
if let fileURL = dir?.appendingPathComponent(fileName).appendingPathExtension("txt") {

    // Write to the file named Test
    let outString = "Write this text to the file"
    do {
        try outString.write(to: fileURL, atomically: true, encoding: .utf8)
    } catch {
        print("Failed writing to URL: \(fileURL), Error: " + error.localizedDescription)
    }

    // Then reading it back from the file
    var inString = ""
    do {
        inString = try String(contentsOf: fileURL)
    } catch {
        print("Failed reading from URL: \(fileURL), Error: " + error.localizedDescription)
    }
    print("Read from the file: \(inString)")
}

For those tuning in a couple years later:

A solution for most browsers (and IE6+) is available that uses the onpropertychange event and the newer spec defineProperty. The slight catch is that you'll need to make your variable a dom object.

This worked for me Visual C++ Redistributable Packages

First import these libraries

import AVFoundation

import AudioToolbox    

set delegate like this

   AVAudioPlayerDelegate

write this pretty code on button action or something action:

guard let url = Bundle.main.url(forResource: "ring", withExtension: "mp3") else { return }
    do {
        try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
        try AVAudioSession.sharedInstance().setActive(true)
        player = try AVAudioPlayer(contentsOf: url, fileTypeHint: AVFileType.mp3.rawValue)
        guard let player = player else { return }

        player.play()
    }catch let error{
        print(error.localizedDescription)
    }

React Native Dimensions is only a partial answer to this question, I came here looking for the actual pixel size of the screen, and the Dimensions actually gives you density independent layout size.

You can use React Native Pixel Ratio to get the actual pixel size of the screen.

You need the import statement for both Dimenions and PixelRatio

import { Dimensions, PixelRatio } from 'react-native';

You can use object destructuring to create width and height globals or put it in stylesheets as others suggest, but beware this won't update on device reorientation.

const { width, height } = Dimensions.get('window');

From React Native Dimension Docs:

Note: Although dimensions are available immediately, they may change (e.g due to >device rotation) so any rendering logic or styles that depend on these constants >should try to call this function on every render, rather than caching the value >(for example, using inline styles rather than setting a value in a StyleSheet).

PixelRatio Docs link for those who are curious, but not much more there.

To actually get the screen size use:

PixelRatio.getPixelSizeForLayoutSize(width);

or if you don't want width and height to be globals you can use it anywhere like this

PixelRatio.getPixelSizeForLayoutSize(Dimensions.get('window').width);

I search the source code inside of Github Repositories with the free Sourcegraph Chrome Extension ... But I Downloaded Chrome First, I knew other browsers support it though, such as - and maybe just only - Firefox.

I skimmed through SourceForge's Chrome Extension Docs and then also I looked at just what I needed for searching for directory names with Github's Search Engine itself, by reading some of Github's Codebase Searching Doc

That's a difficult problem to solve since visually similar PDFs may have a wildly differing structure depending on how they were produced. In the worst case the library would need to basically act like an OCR. On the other hand, the PDF may contain sufficient structure and metadata for easy removal of tables and figures, which the library can be tailored to take advantage of.

I'm pretty sure there are no open source tools which solve your problem for a wide variety of PDFs, but I remember having heard of commercial software claiming to do exactly what you ask for. I'm sure you'll run into them while googling.

You have to install MongoDB database server first in your system and start it.

Use the below link to install MongoDB

https://docs.mongodb.com/manual/installation/

You can use this:

return Content(HttpStatusCode.BadRequest, "Any object");

var baseArrayOfJsonObjects = [{},{}];
for (var i=0; i<arrayOfJsonObjectsFromAjax.length; i++) {
    baseArrayOfJsonObjects.push(arrayOfJsonObjectsFromAjax[i]);
}

Here is an example how to use psql to get a list of all sequences with their last_value:

psql -U <username> -d <database> -t -c "SELECT 'SELECT ''' || c.relname || ''' as sequence_name, last_value FROM ' || c.relname || ';' FROM pg_class c WHERE (c.relkind = 'S')" | psql -U <username> -d <database> -t

You can take a look here for a longer list of screen sizes and respective media queries.

Or go for Bootstrap media queries:

/* Large desktop */
@media (min-width: 1200px) { ... }

/* Portrait tablet to landscape and desktop */
@media (min-width: 768px) and (max-width: 979px) { ... }

/* Landscape phone to portrait tablet */
@media (max-width: 767px) { ... }

/* Landscape phones and down */
@media (max-width: 480px) { ... }

Additionally you might wanty to take a look at Foundation's media queries with the following default settings:

// Media Queries

$screenSmall: 768px !default;
$screenMedium: 1279px !default;
$screenXlarge: 1441px !default;

p1.py:

execfile("p2.py")

p2.py:

import inspect, os
print (inspect.getfile(inspect.currentframe()) # script filename (usually with path)
print (os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe())))) # script directory

Please try this:

byte[] decodedString = Base64.decode(person_object.getPhoto(),Base64.NO_WRAP);
InputStream inputStream  = new ByteArrayInputStream(decodedString);
Bitmap bitmap  = BitmapFactory.decodeStream(inputStream);
user_image.setImageBitmap(bitmap);

I had a similar issue, but I was able to solve mine by specifying explicitly the app_label using Meta Class in my models class

class Meta:
    app_label  = 'name_of_my_app'

Your best bet is to have a look at strptime()

Something along the lines of

>>> from datetime import datetime
>>> date_str = 'Tue May 08 15:14:45 +0800 2012'
>>> date = datetime.strptime(date_str, '%a %B %d %H:%M:%S +0800 %Y')
>>> date
datetime.datetime(2012, 5, 8, 15, 14, 45)

Im not sure how to do the +0800 timezone unfortunately, maybe someone else can help out with that.

The formatting strings can be found at http://docs.python.org/library/time.html#time.strftime and are the same for formatting the string for printing.

Hope that helps

Mark

PS, Your best bet for timezones in installing pytz from pypi. ( http://pytz.sourceforge.net/ ) in fact I think pytz has a great datetime parsing method if i remember correctly. The standard lib is a little thin on the ground with timezone functionality.

Instead, you simply JOIN to both tables, and in your SELECT clause, return data from the one that matches:

I suggest you to go through this link Conditional Joins in SQL Server and T-SQL Case Statement in a JOIN ON Clause

e.g.

    SELECT  *
FROM    sys.indexes i
        JOIN sys.partitions p
            ON i.index_id = p.index_id 
        JOIN sys.allocation_units a
            ON a.container_id =
            CASE
               WHEN a.type IN (1, 3)
                   THEN  p.hobt_id 
               WHEN a.type IN (2)
                   THEN p.partition_id
               END 

Edit: As per comments.

You can not specify the join condition as you are doing.. Check the query above that have no error. I have take out the common column up and the right column value will be evaluated on condition.

First shift the column:

df['gdp'] = df['gdp'].shift(-1)

Second remove the last row which contains an NaN Cell:

df = df[:-1]

Third reset the index:

df = df.reset_index(drop=True)

Personally, I use this function which I created and put in my profile script ...\Documents\WindowsPowerShell\….profile, feel free to use it. As I am from the UK, I prefer to go to .co.uk where possible, if you are from another area, you can add your own country code.

# Function taking parameter add (address) and opens in edge.
Function edge {
    param($add)
    if (-not ($add -contains "https://www." -or $add -contains "http://www.")) {
        if ($add[0] -eq "w" -and $add[1] -eq "w" -and $add[2] -eq "w") {
            $add = "https://" + $add
        } else {
            $add = "https://www." + $add
        }
    }

    # If no domain, tries to add .co.uk, if fails uses .com
    if (-not ($add -match ".co" -or $add -match ".uk" -or $add -match ".com")) {
        try {
            $test = $add + ".co.uk"
            $HTTP_Request  = [System.Net.WebRequest]::Create($test)
            $HTTP_Response = $HTTP_Request.GetResponse()
            $add = $add + ".co.uk"
        } catch{
            $add = $add + ".com"
        }
    }
    Write-Host "Taking you to $add"
    start microsoft-edge:$add
}

Then you just have to call: edge google in powershell to go to https://www.google.co.uk

An easy way that is compatible pretty much everywhere is to set font-size: 0 on the container, provided you don't have any descendent text nodes you need to style (though it is trivial to override this where needed).

.nospace {
   font-size: 0;
}

jsFiddle.

You could also change from the default display: inline into block or inline-block. Be sure to use the workarounds required for <= IE7 (and possibly ancient Firefoxes) for inline-block to work.

To quote:

Because map containers do not allow for duplicate key values, the insertion operation checks for each element inserted whether another element exists already in the container with the same key value, if so, the element is not inserted and its mapped value is not changed in any way.

So insert will not change the value if the key already exists, the [] operator will.

EDIT:

This reminds me of another recent question - why use at() instead of the [] operator to retrieve values from a vector. Apparently at() throws an exception if the index is out of bounds whereas [] operator doesn't. In these situations it's always best to look up the documentation of the functions as they will give you all the details. But in general, there aren't (or at least shouldn't be) two functions/operators that do the exact same thing.

My guess is that, internally, insert() will first check for the entry and afterwards itself use the [] operator.

I would use a ByteArrayOutputStream. And on finish you can call:

new String( baos.toByteArray(), codepage );

or better:

baos.toString( codepage );

For the String constructor, the codepage can be a String or an instance of java.nio.charset.Charset. A possible value is java.nio.charset.StandardCharsets.UTF_8.

The method toString() accepts only a String as a codepage parameter (stand Java 8).

try this:

$prices = array_column($inventory, 'price');
array_multisort($prices, SORT_DESC, $inventory);
print_r($inventory);

Modify to suit your specifics, or make more generic as needed:

Private Sub CopyItOver()
  Set NewBook = Workbooks.Add
  Workbooks("Whatever.xlsx").Worksheets("output").Range("A1:K10").Copy
  NewBook.Worksheets("Sheet1").Range("A1").PasteSpecial (xlPasteValues)
  NewBook.SaveAs FileName:=NewBook.Worksheets("Sheet1").Range("E3").Value
End Sub

I always thought this was one of the better articles on the subject. It includes the following example that I think makes it clear and includes the frequently overlooked @@trancount which is needed for reliable nested transactions

PRINT 'BEFORE TRY'
BEGIN TRY
    BEGIN TRAN
     PRINT 'First Statement in the TRY block'
     INSERT INTO dbo.Account(AccountId, Name , Balance) VALUES(1, 'Account1',  10000)
     UPDATE dbo.Account SET Balance = Balance + CAST('TEN THOUSAND' AS MONEY) WHERE AccountId = 1
     INSERT INTO dbo.Account(AccountId, Name , Balance) VALUES(2, 'Account2',  20000)
     PRINT 'Last Statement in the TRY block'
    COMMIT TRAN
END TRY
BEGIN CATCH
    PRINT 'In CATCH Block'
    IF(@@TRANCOUNT > 0)
        ROLLBACK TRAN;

    THROW; -- raise error to the client
END CATCH
PRINT 'After END CATCH'
SELECT * FROM dbo.Account WITH(NOLOCK)
GO

I want to disable button on some condition, i am using 1st solution but it won't work for me. But when I use 2nd one it worked.Below are outputs from browser console.

<a class=?"btn btn-yellow btn-continue" href=?"#">?Next?</a>?

2. $('#psl2 .btn-continue').attr("disabled","disabled")

<a class=?"btn btn-yellow btn-continue" href=?"#" disabled=?"disabled">?Next?</a>?

Had a similar issue while installing "Lua" in OS X using homebrew. I guess it could be useful for other users facing similar issue in homebrew.

On running the command:

$ brew install lua

The command returned an error:

Error: /usr/local/opt/lua is not a valid keg
(in general the error can be of /usr/local/opt/ is not a valid keg

FIXED it by deleting the file/directory it is referring to, i.e., deleting the "/usr/local/opt/lua" file.

root-user # rm -rf /usr/local/opt/lua

And then running the brew install command returned success.

My problem

get_courses(); //// To load the course list
$("#course").val(course); //// Setting default value of the list

I had the same issue . The Only difference from your code is that I was loading the select box through an ajax call and soon as the ajax call was executed I had set the default value of the select box

The Solution

get_courses();
   setTimeout(function() {
     $("#course").val(course);
  }, 10);

you can try this way:

Fragment currentFragment = getFragmentManager().findFragmentById(R.id.fragment_container);

or

Fragment currentFragment = getSupportFragmentManager().findFragmentById(R.id.fragment_container);

In this if, you check if currentFragment is instance of YourFragment

if (currentFragment instanceof YourFragment) {
     Log.v(TAG, "your Fragment is Visible");
}

Concatenation:

The string concatenation operator in Lua is denoted by two dots ('..'). If both operands are strings or numbers, then they are converted to strings according to the rules mentioned in §2.2.1. Otherwise, the "concat" metamethod is called (see §2.8).

from: http://www.lua.org/manual/5.1/manual.html#2.5.4

To add to the response from @Anish, if you are having issues with not seeing the text when exporting the SVG to an image, you can create a recursive function to loop through the children of the SVGDocument, try to cast it to a SvgText if possible (add your own error checking) and set the font family and style.

    foreach(var child in svgDocument.Children)
    {
        SetFont(child);
    }

    public void SetFont(SvgElement element)
    {
        foreach(var child in element.Children)
        {
            SetFont(child); //Call this function again with the child, this will loop
                            //until the element has no more children
        }

        try
        {
            var svgText = (SvgText)parent; //try to cast the element as a SvgText
                                           //if it succeeds you can modify the font

            svgText.Font = new Font("Arial", 12.0f);
            svgText.FontSize = new SvgUnit(12.0f);
        }
        catch
        {

        }
    }

Let me know if there are questions.

To bind socket with localhost, before you invoke the bind function, sin_addr.s_addr field of the sockaddr_in structure should be set properly. The proper value can be obtained either by

my_sockaddress.sin_addr.s_addr = inet_addr("127.0.0.1")

or by

my_sockaddress.sin_addr.s_addr=htonl(INADDR_LOOPBACK);

I just want to have a button on my website make a PHP file run

<form action="my.php" method="post">
    <input type="submit">
</form>

Generally speaking, however, unless you are sending new data to the server to be stored, you would just use a link.

<a href="my.php">run php</a>

(Although you should use link text that describes what happens from the user's point of view, not the servers)

I'm making a simple blog site for myself and I've got the code for the site and the javascript that can take the post I write in a textarea and display it immediately. I just want to link it to a PHP file that will create the permanent blog post on the server so that when I reload the page, the post is still there.

This is tricker.

First, you do need to use a form and POST (since you are sending data to be stored).

Then you need to store the data somewhere. This is normally done using a database. Read up on the PDO library for PHP. It is the standard way to interact with databases.

Then you need to pull the data back out again. The simplest approach here is to use the query string to pass the primary key for the database row with the entry you wish to display.

<a href="showBlogEntry.php?entry_id=123">...</a>

Make sure you also read up on SQL injection and XSS.

You can add a JAR which having above specified class exist e.g.ojdbc jar which supported by installed java version, also make sure that you have added it into classpath.

There is an NPM package is-html that can attempt to solve this https://github.com/sindresorhus/is-html

Try this:

^\d\d[./-]\d\d[./-]\d\d\d\d$

When the branch is no remote branch you can push your local branch direct to the remote.

git checkout master
git push origin master

or when you have a dev branch

git checkout dev
git push origin dev

or when the remote branch exists

git branch dev -t origin/dev

There are some other posibilites to push a remote branch.

I prefer using function pointers over gigantic switch statements, but in contrast to qrdl's answer I normally don't use explicit return codes or transition tables.

Also, in most cases you'll want a mechanism to pass along additional data. Here's an example state machine:

#include <stdio.h>

struct state;
typedef void state_fn(struct state *);

struct state
{
    state_fn * next;
    int i; // data
};

state_fn foo, bar;

void foo(struct state * state)
{
    printf("%s %i\n", __func__, ++state->i);
    state->next = bar;
}

void bar(struct state * state)
{
    printf("%s %i\n", __func__, ++state->i);
    state->next = state->i < 10 ? foo : 0;
}

int main(void)
{
    struct state state = { foo, 0 };
    while(state.next) state.next(&state);
}

before you get too excited this was written in 2011

if I were to do this these days I would use Intl.DateTimeFormat. Here is a link to give you an idea of what type of support this had in 2011

original answer now (very) outdated

Date.getTimezoneOffset()

The getTimezoneOffset() method returns the time difference between Greenwich Mean Time (GMT) and local time, in minutes.

For example, If your time zone is GMT+2, -120 will be returned.

Note: This method is always used in conjunction with a Date object.

var d = new Date()
var gmtHours = -d.getTimezoneOffset()/60;
document.write("The local time zone is: GMT " + gmtHours);
//output:The local time zone is: GMT 11

Use regular expression no need to convert it to char array

if(Regex.IsMatch("yourString",".*?[a-zA-Z].*?"))
{
errorCounter++;
}

For a couple of years I was a supporter of using a specific .gitignore for IntelliJ with this suggested configuration.

Not anymore.

IntelliJ is updated quite frequently, internal config file specs change more often than I would like and JetBrains flagship excels at auto-configuring itself based on maven/gradle/etc build files.

So my suggestion would be to leave all editor config files out of project and have users configure editor to their liking. Things like code styling can and should be configured at build level; say using Google Code Style or CheckStyle directly on Maven/Gradle/sbt/etc.

This ensures consistency and leaves editor files out of source code that, in my personal opinion, is where they should be.

Use bash builtin redirection (tldp):

cat file2 >> file1

I find std::getline() is often the simplest. The optional delimiter parameter means it's not just for reading "lines":

#include <sstream>
#include <iostream>
#include <vector>

using namespace std;

int main() {
    vector<string> strings;
    istringstream f("denmark;sweden;india;us");
    string s;    
    while (getline(f, s, ';')) {
        cout << s << endl;
        strings.push_back(s);
    }
}

You really shouldn't be doing that in SQL - you should be formatting it in the middleware instead. But I recognize that sometimes there is an edge case that requires one to do such a thing.

This looks like it might have your answer:

How do I format a number with commas in T-SQL?

You could also use INDEX MATCH, which is more "powerful" than vlookup. This would give you exactly what you are looking for:

Easy, just define your own function that does what you want:

def enum(seq, start=0):
    for i, x in enumerate(seq):
        yield i+start, x

You can use SQLiteOpenHelper's onUpgrade method. In the onUpgrade method, you get the oldVersion as one of the parameters.

In the onUpgrade use a switch and in each of the cases use the version number to keep track of the current version of database.

It's best that you loop over from oldVersion to newVersion, incrementing version by 1 at a time and then upgrade the database step by step. This is very helpful when someone with database version 1 upgrades the app after a long time, to a version using database version 7 and the app starts crashing because of certain incompatible changes.

Then the updates in the database will be done step-wise, covering all possible cases, i.e. incorporating the changes in the database done for each new version and thereby preventing your application from crashing.

For example:

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    switch (oldVersion) {
    case 1:
        String sql = "ALTER TABLE " + TABLE_SECRET + " ADD COLUMN " + "name_of_column_to_be_added" + " INTEGER";
        db.execSQL(sql);
        break;

    case 2:
        String sql = "SOME_QUERY";
        db.execSQL(sql);
        break;
    }

}

You will also get this error if you have a generic declaration for both your class and your method. For example the code shown below gives this compile error.

public class Foo <T> {

    T var;

    public <T> void doSomething(Class <T> cls) throws InstantiationException, IllegalAccessException {
        this.var = cls.newInstance();
    }

}

This code does compile (note T removed from method declaration):

public class Foo <T> {

    T var;

    public void doSomething(Class <T> cls) throws InstantiationException, IllegalAccessException {
        this.var = cls.newInstance();
    }

}

I took yckart's answer and:

• spaced it out for readability
• case insensitive search
• there was a bug in the comparison that was fixed by adding .trim()

(If you put your scripts at the bottom of your page below the jQuery include you shouldn't need document ready)

jQuery:

 <script>
    $(".card-table-search").keyup(function() {
        var value = this.value.toLowerCase().trim();

        $(".card-table").find("tr").each(function(index) {
            var id = $(this).find("td").first().text().toLowerCase().trim();
            $(this).toggle(id.indexOf(value) !== -1);
        });
    });
 </script>

If you want to extend this have it iterate over each 'td' and do this comparison.

implements means a behaviour will be defined for abstract methods (except for abstract classes obviously), you define the implementation.

extends means that a behaviour is inherited.

With interfaces it is possible to say that one interface should have that the same behaviour as another, there is not even an actual implementation. That's why it makes more sense for an interface to extends another interface instead of implementing it.

On a side note, remember that even if an abstract class can define abstract methods (the sane way an interface does), it is still a class and still has to be inherited (extended) and not implemented.

On linux you can do the following:

$cmd = 'nohup nice -n 10 php -f php/file.php > log/file.log & printf "%u" $!';
$pid = shell_exec($cmd);

This will execute the command at the command prompty and then just return the PID, which you can check for > 0 to ensure it worked.

This question is similar: Does PHP have threading?

In my case, problem was due to low disk space. I want to mention it for other users like me :)

This question touches a very stinking part of the "famous" and "obvious" Python syntax - what takes precedence, the lambda, or the for of list comprehension.

I don't think the purpose of the OP was to generate a list of squares from 0 to 9. If that was the case, we could give even more solutions:

squares = []
for x in range(10): squares.append(x*x)

• this is the good ol' way of imperative syntax.

But it's not the point. The point is W(hy)TF is this ambiguous expression so counter-intuitive? And I have an idiotic case for you at the end, so don't dismiss my answer too early (I had it on a job interview).

So, the OP's comprehension returned a list of lambdas:

[(lambda x: x*x) for x in range(10)]

This is of course just 10 different copies of the squaring function, see:

>>> [lambda x: x*x for _ in range(3)]
[<function <lambda> at 0x00000000023AD438>, <function <lambda> at 0x00000000023AD4A8>, <function <lambda> at 0x00000000023AD3C8>]

Note the memory addresses of the lambdas - they are all different!

You could of course have a more "optimal" (haha) version of this expression:

>>> [lambda x: x*x] * 3
[<function <lambda> at 0x00000000023AD2E8>, <function <lambda> at 0x00000000023AD2E8>, <function <lambda> at 0x00000000023AD2E8>]

See? 3 time the same lambda.

Please note, that I used _ as the for variable. It has nothing to do with the x in the lambda (it is overshadowed lexically!). Get it?

I'm leaving out the discussion, why the syntax precedence is not so, that it all meant:

[lambda x: (x*x for x in range(10))]

which could be: [[0, 1, 4, ..., 81]], or [(0, 1, 4, ..., 81)], or which I find most logical, this would be a list of 1 element - a generator returning the values. It is just not the case, the language doesn't work this way.

BUT What, If...

What if you DON'T overshadow the for variable, AND use it in your lambdas???

Well, then crap happens. Look at this:

[lambda x: x * i for i in range(4)]

this means of course:

[(lambda x: x * i) for i in range(4)]

BUT it DOESN'T mean:

[(lambda x: x * 0), (lambda x: x * 1), ... (lambda x: x * 3)]

This is just crazy!

The lambdas in the list comprehension are a closure over the scope of this comprehension. A lexical closure, so they refer to the i via reference, and not its value when they were evaluated!

So, this expression:

[(lambda x: x * i) for i in range(4)]

IS roughly EQUIVALENT to:

[(lambda x: x * 3), (lambda x: x * 3), ... (lambda x: x * 3)]

I'm sure we could see more here using a python decompiler (by which I mean e.g. the dis module), but for Python-VM-agnostic discussion this is enough. So much for the job interview question.

Now, how to make a list of multiplier lambdas, which really multiply by consecutive integers? Well, similarly to the accepted answer, we need to break the direct tie to i by wrapping it in another lambda, which is getting called inside the list comprehension expression:

Before:

>>> a = [(lambda x: x * i) for i in (1, 2)]
>>> a[1](1)
2
>>> a[0](1)
2

After:

>>> a = [(lambda y: (lambda x: y * x))(i) for i in (1, 2)]
>>> a[1](1)
2
>>> a[0](1)
1

(I had the outer lambda variable also = i, but I decided this is the clearer solution - I introduced y so that we can all see which witch is which).

Edit 2019-08-30:

Following a suggestion by @josoler, which is also present in an answer by @sheridp - the value of the list comprehension "loop variable" can be "embedded" inside an object - the key is for it to be accessed at the right time. The section "After" above does it by wrapping it in another lambda and calling it immediately with the current value of i. Another way (a little bit easier to read - it produces no 'WAT' effect) is to store the value of i inside a partial object, and have the "inner" (original) lambda take it as an argument (passed supplied by the partial object at the time of the call), i.e.:

After 2:

>>> from functools import partial
>>> a = [partial(lambda y, x: y * x, i) for i in (1, 2)]
>>> a[0](2), a[1](2)
(2, 4)

Great, but there is still a little twist for you! Let's say we wan't to make it easier on the code reader, and pass the factor by name (as a keyword argument to partial). Let's do some renaming:

After 2.5:

>>> a = [partial(lambda coef, x: coef * x, coef=i) for i in (1, 2)]
>>> a[0](1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: <lambda>() got multiple values for argument 'coef'

WAT?

>>> a[0]()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: <lambda>() missing 1 required positional argument: 'x'

Wait... We're changing the number of arguments by 1, and going from "too many" to "too few"?

Well, it's not a real WAT, when we pass coef to partial in this way, it becomes a keyword argument, so it must come after the positional x argument, like so:

After 3:

>>> a = [partial(lambda x, coef: coef * x, coef=i) for i in (1, 2)]
>>> a[0](2), a[1](2)
(2, 4)

I would prefer the last version over the nested lambda, but to each their own...

Edit 2020-08-18:

Thanks to commenter dasWesen, I found out that this stuff is covered in the Python documentation: https://docs.python.org/3.4/faq/programming.html#why-do-lambdas-defined-in-a-loop-with-different-values-all-return-the-same-result - it deals with loops instead of list comprehensions, but the idea is the same - global or nonlocal variable access in the lambda function. There's even a solution - using default argument values (like for any function):

>>> a = [lambda x, coef=i: coef * x for i in (1, 2)]
>>> a[0](2), a[1](2)
(2, 4)

This way the coef value is bound to the value of i at the time of function definition (see James Powell's talk "Top To Down, Left To Right", which also explains why mutable default values are shunned).

I can think of three options:

Implement RFC 2217

RFC 2217 covers a com port to TCP/IP standard that allows a client on one system to emulate a serial port to the local programs, while transparently sending and receiving data and control signals to a server on another system which actually has the serial port. Here's a high-level overview.

What you would do is find or implement a client com port driver that would implement the client side of the system on your PC - appearing to be a real serial port but in reality shuttling everything to a server. You might be able to get this driver for free from Digi, Lantronix, etc in support of their real standalone serial port servers.

You would then implement the server side of the connection locally in another program - allowing the client to connect and issuing the data and control commands as needed.

It's probably non trivial, but the RFC is out there, and you might be able to find an open source project that implements one or both sides of the connection.

Modify the linux serial port driver

Alternately, the serial port driver source for Linux is readily available. Take that, gut the hardware control pieces, and have that one driver run two /dev/ttySx ports, as a simple loopback. Then connect your real program to the ttyS2 and your simulator to the other ttySx.

Use two USB<-->Serial cables in a loopback

But the easiest thing to do right now? Spend $40 on two serial port USB devices, wire them together (null modem) and actually have two real serial ports - one for the program you're testing, one for your simulator.

I think that the thing you must keep in mind is that your XML is being processed by a machine, not a human, so it only needs to be readable for the machine.

In other words, I think you should use whatever XML schema you need to make parsing/processing the rules as efficient as possible at run time.

As far as your current schema goes, I think that the id attribute should be unique per element, so perhaps you should use a different attribute to capture the relationship among your IF, THEN, and ELSE elements.

This has happened to me several times and the way I solved it was :

1. Check and make sure your Vagrantfile has the correct private key path :

   config.ssh.private_key_path = "/home/razvan/.ssh/id_rsa"

2. Execute > vagrant ssh command in a linux terminal

3. On your vagrant machine go to

   cd /home/vagrant/.ssh

and check if the ssh key in the authorized_keys file is the same as the one you have on your local machine in ~/.ssh/id_rsa.pub. If not replace the one from your vagrant authorized_keys with the one on your local machine found in ~/.ssh/id_rsa.pub.

4. Reload Vagrant :

   vagrant reload

Hope this helps someone else. Cheers!

Where do you want to see the output?

Messages being output via Debug.Print will be displayed in the immediate window which you can open by pressing Ctrl+G.

You can also Activate the so called Immediate Window by clicking View -> Immediate Window on the VBE toolbar

The simplest by far will be Simple http://simple.sourceforge.net, you only need to annotate a single object like so

@Root
public class Entry {

   @Attribute
   private String a
   @Attribute
   private int b;
   @Element
   private Date c;

   public String getSomething() {
      return a;
   }
} 

@Root
public class Configuration {

   @ElementList(inline=true)
   private List<Entry> entries;

   public List<Entry> getEntries() { 
      return entries;
   }
}

Then all you have to do to read the whole file is specify the location and it will parse and populate the annotated POJO's. This will do all the type conversions and validation. You can also annotate for persister callbacks if required. Reading it can be done like so.

Serializer serializer = new Persister();
Configuration configuraiton = serializer.read(Configuration.class, fileLocation);

AFAIK there isn't a built-in mechanism in Eclipse for this.

The closest you can get is to create a wrapper that prompts you for these values and invokes the (hardcoded) main. You then get you execution history as long as you don't clear terminated processes. Two variations on this are either to use JUNit, or to use injection or parameter so that your wrapper always connects to the correct class for its main.

Also be sure to set your JAVA_HOME environment variable. In fact, I usually set the JAVA_HOME, then prepend the string "%JAVA_HOME%\bin" to the system's PATH environment variable so that if Java ever gets upgraded or changed, only the JAVA_HOME variable will need to be changed.

And make sure that you close any command prompt windows or open applications that may read your environment variables, as changes to environment variables are normally not noticed until an application is re-launched.

I had the same problem. But I also had to perform additional steps. Here is what I did.

Perform the following steps (Only 64bit version of SQL Server 2005 Developer Edition tested on Windows 8 Pro 64bit)

1. Extract sqlncli.msi / sqlncli_x64.msi from SP3 or SP4. I did it from SP4
2. Install sqlncli
3. Start SQL Server 2005 Setup
4. During setup I received an error The SQL Server service failed to start. For more information, see the SQL Server Books Online topics, "How to: View SQL Server 2005 Setup Log Files" and "Starting SQL Server Manually."
5. Don't click cancel yet. From an installation of SQL Server 2005 SP3 or SP4 copy SQLSERVR.EXE and SQLOS.DLL files and put them in your SQL install folder.
6. Click RETRY

For STEP 5 above: Although I didn't try looking into SP4 / SP3 setup for SQLSERVR.EXE and SQLOS.DLL but if you don't have an existing installation of SQL Server 2005 SP3/SP4 then maybe try looking into the SP3/SP4 EXE (Compressed file). I am not sure if this may help. In any case you can create a VM and install SQL Server 2005 with SP3/Sp4 to copy the files for Windows 8

The following will return '0' if the string consists entirely of zeros:

CASE WHEN SUBSTRING(str_col, PATINDEX('%[^0]%', str_col+'.'), LEN(str_col)) = '' THEN '0' ELSE SUBSTRING(str_col, PATINDEX('%[^0]%', str_col+'.'), LEN(str_col)) END AS str_col

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

You need to use the await keyword when use async and your function return type should be generic Here is an example with return value:

public async Task<object> MethodName()
{
    return await Task.FromResult<object>(null);
}

Here is an example with no return value:

public async Task MethodName()
{
    await Task.CompletedTask;
}

For Empty row how we can insert values on where clause

Try this

UPDATE table_name SET username="",password="" WHERE id =""

You can run from Java code.

try {

        File file = new File(keystore location);
        InputStream is = new FileInputStream(file);
        KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());
        String password = "password";
        keystore.load(is, password.toCharArray());


        Enumeration<String> enumeration = keystore.aliases();
        while(enumeration.hasMoreElements()) {
            String alias = enumeration.nextElement();
            System.out.println("alias name: " + alias);
            Certificate certificate = keystore.getCertificate(alias);
            System.out.println(certificate.toString());

        }

    } catch (java.security.cert.CertificateException e) {
        e.printStackTrace();
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (KeyStoreException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }finally {
        if(null != is)
            try {
                is.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
    }

Certificate class holds all information about the keystore.

UPDATE- OBTAIN PRIVATE KEY

Key key = keyStore.getKey(alias, password.toCharArray());
String encodedKey = new Base64Encoder().encode(key.getEncoded());
System.out.println("key ? " + encodedKey);

@prateek Hope this is what you looking for!

Here is way I tried and found useful,

URL u = new URL(name); // this would check for the protocol
u.toURI(); // does the extra checking required for validation of URI 

I don't think there's any way you can do it in XML layout file, and I don't think android:scaleType attribute will work like you want it to be.
The only way would be to do it programmatically. You can set the width to fill_parent and can either take screen width as the height of the View or can use View.getWidth() method.

Take a look at Declarative Razor Helpers

Here is a complete list of steps - you may not need steps 1-3 but am including them for completeness:-

1. Download VS Code and Apache Maven and install both.
2. Install the Visual Studio extension pack for Java - e.g. by pasting this URL into a web browser: vscode:extension/vscjava.vscode-java-pack and then clicking on the green Install button after it opens in VS Code.
3. NOTE: See the comment from ADTC for an "Easier GUI version of step 3...(Skip step 4)." If necessary, the Maven quick start archetype could be used to generate a new Maven project in an appropriate local folder: mvn archetype:generate -DgroupId=com.companyname.appname-DartifactId=appname-DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false. This will create an appname folder with Maven's Standard Directory Layout (i.e. src/main/java/com/companyname/appname and src/main/test/com/companyname/appname to begin with and a sample "Hello World!" Java file named appname.java and associated unit test named appnameTest.java).*
4. Open the Maven project folder in VS Code via File menu -> Open Folder... and select the appname folder.
5. Open the Command Palette (via the View menu or by right-clicking) and type in and select Tasks: Configure task then select Create tasks.json from template.

6. Choose maven ("Executes common Maven commands"). This creates a tasks.json file with "verify" and "test" tasks. More can be added corresponding to other Maven Build Lifecycle phases. To specifically address your requirement for classes to be built without a JAR file, a "compile" task would need to be added as follows:

   {
       "label": "compile",
       "type": "shell",
       "command": "mvn -B compile",
       "group": "build"
   },
   

7. Save the above changes and then open the Command Palette and select "Tasks: Run Build Task" then pick "compile" and then "Continue without scanning the task output". This invokes Maven, which creates a target folder at the same level as the src folder with the compiled class files in the target\classes folder.

Addendum: How to run/debug a class

Following a question in the comments, here are some steps for running/debugging:-

1. Show the Debug view if it is not already shown (via View menu - Debug or CtrlShiftD).
2. Click on the green arrow in the Debug view and select "Java".
3. Assuming it hasn't already been created, a message "launch.json is needed to start the debugger. Do you want to create it now?" will appear - select "Yes" and then select "Java" again.
4. Enter the fully qualified name of the main class (e.g. com.companyname.appname.App) in the value for "mainClass" and save the file.
5. Click on the green arrow in the Debug view again.

I prefer the Boost Timer library for its simplicity, but if you don't want to use third-parrty libraries, using clock() seems reasonable.

There's also solution for Node JS app. CORS Anywhere is a NodeJS proxy which adds CORS headers to the proxied request.

The url to proxy is literally taken from the path, validated and proxied. The protocol part of the proxied URI is optional, and defaults to "http". If port 443 is specified, the protocol defaults to "https".

This package does not put any restrictions on the http methods or headers, except for cookies. Requesting user credentials is disallowed. The app can be configured to require a header for proxying a request, for example to avoid a direct visit from the browser. https://robwu.nl/cors-anywhere.html

You can do this in two ways:

1. ElementMatch - $elemMatch (as explained in above answers)

   db.users.find({ awards: { $elemMatch: {award:'Turing Award', year:1977} } })

2. Use $and with find

   db.getCollection('users').find({"$and":[{"awards.award":"Turing Award"},{"awards.year":1977}]})

It does WAY more than "just sorting", but dataTables.net does what you need. I use it daily and is well supported and VERY fast (does require jQuery)

http://datatables.net/

DataTables is a plug-in for the jQuery Javascript library. It is a highly flexible tool, based upon the foundations of progressive enhancement, which will add advanced interaction controls to any HTML table.

Google Visualizations is another option, but requires a bit more setup that dataTables, but does NOT require any particular framework/library (other than google.visualizations):

http://code.google.com/apis/ajax/playground/?type=visualization#table

And there are other options to... especially if you're using one of the other JS frameworks. Dojo, Prototype, etc all have usable "table enhancement" plugins that provide at minimum table sorting functionality. Many provide more, but I'll restate...I've yet to come across one as powerful and as FAST as datatables.net.

I asked the same question myself over here, and just posted an answer that I recently found. Short answer is: inject a SecurityContext, and refer to SecurityContextHolder only in your Spring config to obtain the SecurityContext

Request.Form is a NameValueCollection. In NameValueCollection you can find the GetAllValues() method.

By the way the LINQ method also works.

I use the below query for tracing application activity on a SQL server that does not have trace profiler enabled. The method uses Query Store (SQL Server 2016+) instead of the DMV's. This gives better ability to look into historical data, as well as faster lookups. It is very efficient to capture short-running queries that can't be captured by sp_who/sp_whoisactive.

    Run full script (F5) -> Interact with UI -> Run full script again (F5)

I'm not familiar with PDFBox, but you could try looking at itext. Even though the homepage says PDF generation, you can also do PDF manipulation and extraction. Have a look and see if it fits your use case.

You can't inject content from another site (domain) using AJAX. The reason an iFrame is suited for these kinds of things is that you can specify the source to be from another domain.

The idiomatic way is to say:

if(rsData["usr.ursrdaystime"] != DBNull.Value) {
    strLevel = rsData["usr.ursrdaystime"].ToString();
}

This:

rsData = objCmd.ExecuteReader();
rsData.Read();

Makes it look like you're reading exactly one value. Use IDbCommand.ExecuteScalar instead.

Which one to use

Transient

• since they are created every time they will use more memory & Resources and can have the negative impact on performance
• use this for the lightweight service with little or no state.

Scoped

• better option when you want to maintain state within a request.

Singleton

• memory leaks in these services will build up over time.
• also memory efficient as they are created once reused everywhere.

Use Singletons where you need to maintain application wide state. Application configuration or parameters, Logging Service, caching of data is some of the examples where you can use singletons.

Injecting service with different lifetimes into another

1. Never inject Scoped & Transient services into Singleton service. ( This effectively converts the transient or scoped service into the singleton.)
2. Never inject Transient services into scoped service ( This converts the transient service into the scoped. )

If you can safely make (firstName, lastName) the PRIMARY KEY or at least put a UNIQUE key on them, then you could do this:

INSERT INTO logins (firstName, lastName, logins) VALUES ('Steve', 'Smith', 1)
ON DUPLICATE KEY UPDATE logins = logins + 1;

If you can't do that, then you'd have to fetch whatever that primary key is first, so I don't think you could achieve what you want in one query.

to convert CString to std::string. You can use this format.

std::string sText(CW2A(CSText.GetString(), CP_UTF8 ));

I think refilling the same adapter with different data would be more or most better technique. Put this method in your Adapter class with right argument (the data list you want to display as names in my case) Call this where u update the data of list with updated list (names in my case)

public void refill(ArrayList<BeanDatabase> names) {
    list.clear();
    list.addAll(names);
    list.notifyDataSetChanged();
}

If you change the adapter or set the adapter again and again on when the list updates, then force close error would surely cause problems at some point. (Error:List data been updated but adapter doesn't notify the List View)

The example creates a list of named lists in a loop.

  MyList <- list()
  for (aName in c("name1", "name2")){
    MyList[[aName]] <- list(aName)
  }
  MyList[["name1"]]
  MyList[["name2"]]

To add another list named "name3" do write:

  MyList$name3 <- list(1, 2, 3)

Yes, you want to use tee:

tee - read from standard input and write to standard output and files

Just pipe your command to tee and pass the file as an argument, like so:

exec 1 | tee ${LOG_FILE}
exec 2 | tee ${LOG_FILE}

This both prints the output to the STDOUT and writes the same output to a log file. See man tee for more information.

Note that this won't write stderr to the log file, so if you want to combine the two streams then use:

exec 1 2>&1 | tee ${LOG_FILE}

Please try this:

#b {
display: -webkit-inline-flex;
display: -moz-inline-flex;
display: inline-flex;

-webkit-flex-flow: row nowrap;
-moz-flex-flow: row nowrap;
flex-flow: row nowrap;

-webkit-align-items: flex-end;
-moz-align-items: flex-end;
align-items: flex-end;}

Here's a JSFiddle demo: http://jsfiddle.net/rudiedirkx/7FGKN/.

    DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern("MM/dd/uuuu");
    System.out.println(LocalDate.parse("08/16/2011", dateFormatter));

Output:

2011-08-16

I am contributing the modern answer. The answer by Bohemian is correct and was a good answer when it was written 6 years ago. Now the notoriously troublesome SimpleDateFormat class is long outdated and we have so much better in java.time, the modern Java date and time API. I warmly recommend you use this instead of the old date-time classes.

What went wrong in your code?

When I parse 08/16/2011 using your snippet, I get Sun Jan 16 00:08:00 CET 2011. Since lowercase mm is for minutes, I get 00:08:00 (8 minutes past midnight), and since uppercase DD is for day of year, I get 16 January.

In java.time too format pattern strings are case sensitive, and we needed to use uppercase MM for month and lowercase dd for day of month.

Question: Can I use java.time with my Java version?

Yes, java.time works nicely on Java 6 and later and on both older and newer Android devices.

• In Java 8 and later and on new Android devices (from API level 26, I’m told) the modern API comes built-in.
• In Java 6 and 7 get the ThreeTen Backport, the backport of the new classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

• Oracle tutorial: Date Time explaining how to use java.time.
• Java Specification Request (JSR) 310, where java.time was first described.

itertools.groupby almost does what you want, except it requires the items to be sorted to ensure that you get a single contiguous range, so you need to sort by your key first (otherwise you'll get multiple interleaved groups for each type). eg.

def is_good(f):
    return f[2].lower() in IMAGE_TYPES

files = [ ('file1.jpg', 33L, '.jpg'), ('file2.avi', 999L, '.avi'), ('file3.gif', 123L, '.gif')]

for key, group in itertools.groupby(sorted(files, key=is_good), key=is_good):
    print key, list(group)

gives:

False [('file2.avi', 999L, '.avi')]
True [('file1.jpg', 33L, '.jpg'), ('file3.gif', 123L, '.gif')]

Similar to the other solutions, the key func can be defined to divide into any number of groups you want.

Complete copy-paste working image picker for swift 4 based on @user3182143 answer:

import Foundation
import UIKit


class ImagePickerManager: NSObject, UIImagePickerControllerDelegate, UINavigationControllerDelegate {

    var picker = UIImagePickerController();
    var alert = UIAlertController(title: "Choose Image", message: nil, preferredStyle: .actionSheet)
    var viewController: UIViewController?
    var pickImageCallback : ((UIImage) -> ())?;
    
    override init(){
        super.init()
        let cameraAction = UIAlertAction(title: "Camera", style: .default){
            UIAlertAction in
            self.openCamera()
        }
        let galleryAction = UIAlertAction(title: "Gallery", style: .default){
            UIAlertAction in
            self.openGallery()
        }
        let cancelAction = UIAlertAction(title: "Cancel", style: .cancel){
            UIAlertAction in
        }

        // Add the actions
        picker.delegate = self
        alert.addAction(cameraAction)
        alert.addAction(galleryAction)
        alert.addAction(cancelAction)
    }

    func pickImage(_ viewController: UIViewController, _ callback: @escaping ((UIImage) -> ())) {
        pickImageCallback = callback;
        self.viewController = viewController;

        alert.popoverPresentationController?.sourceView = self.viewController!.view

        viewController.present(alert, animated: true, completion: nil)
    }
    func openCamera(){
        alert.dismiss(animated: true, completion: nil)
        if(UIImagePickerController .isSourceTypeAvailable(.camera)){
            picker.sourceType = .camera
            self.viewController!.present(picker, animated: true, completion: nil)
        } else {
            let alertWarning = UIAlertView(title:"Warning", message: "You don't have camera", delegate:nil, cancelButtonTitle:"OK", otherButtonTitles:"")
            alertWarning.show()
        }
    }
    func openGallery(){
        alert.dismiss(animated: true, completion: nil)
        picker.sourceType = .photoLibrary
        self.viewController!.present(picker, animated: true, completion: nil)
    }

    
    func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
        picker.dismiss(animated: true, completion: nil)
    }
    //for swift below 4.2
    //func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
    //    picker.dismiss(animated: true, completion: nil)
    //    let image = info[UIImagePickerControllerOriginalImage] as! UIImage
    //    pickImageCallback?(image)
    //}
    
    // For Swift 4.2+
    func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
        picker.dismiss(animated: true, completion: nil)
        guard let image = info[.originalImage] as? UIImage else {
            fatalError("Expected a dictionary containing an image, but was provided the following: \(info)")
        }
        pickImageCallback?(image)
    }



    @objc func imagePickerController(_ picker: UIImagePickerController, pickedImage: UIImage?) {
    }

}

Call it from your viewcontroller like this:

    ImagePickerManager().pickImage(self){ image in
        //here is the image
    }

Also don't forget to include the following keys in your info.plist:

<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

Another technique to consider if you want to compare a file to the last commit which is more pedantic:

git diff master myfile.txt

The advantage with this technique is you can also compare to the penultimate commit with:

git diff master^ myfile.txt

and the one before that:

git diff master^^ myfile.txt

Also you can substitute '~' for the caret '^' character and 'you branch name' for 'master' if you are not on the master branch.

It should also be mentioned that <span> tags allow inside them -- block-level items negate MD natively inside them unless you configure them not to do so, but in-line styles natively allow MD within them. As such, I often do something akin to...

This is a superfluous paragraph thing.

<span class="class-red">And thus I delve into my topic, Lorem ipsum lollipop bubblegum.</span>

And thus with that I conclude.

I am not 100% sure if this is universal but seems to be the case in all MD editors I've used.

Definition

Aggregate method is an extension method for generic collections. Aggregate method applies a function to each item of a collection. Not just only applies a function, but takes its result as initial value for the next iteration. So, as a result, we will get a computed value (min, max, avg, or other statistical value) from a collection.

Therefore, Aggregate method is a form of safe implementation of a recursive function.

Safe, because the recursion will iterate over each item of a collection and we can’t get any infinite loop suspension by wrong exit condition. Recursive, because the current function’s result is used as a parameter for the next function call.

Syntax:

collection.Aggregate(seed, func, resultSelector);

• seed - initial value by default;
• func - our recursive function. It can be a lambda-expression, a Func delegate or a function type T F(T result, T nextValue);
• resultSelector - it can be a function like func or an expression to compute, transform, change, convert the final result.

How it works:

var nums = new[]{1, 2};
var result = nums.Aggregate(1, (result, n) => result + n); //result = (1 + 1) + 2 = 4
var result2 = nums.Aggregate(0, (result, n) => result + n, response => (decimal)response/2.0); //result2 = ((0 + 1) + 2)*1.0/2.0 = 3*1.0/2.0 = 3.0/2.0 = 1.5

Practical usage:

1. Find Factorial from a number n:

int n = 7;
var numbers = Enumerable.Range(1, n);
var factorial = numbers.Aggregate((result, x) => result * x);

which is doing the same thing as this function:

public static int Factorial(int n)
{
   if (n < 1) return 1;

   return n * Factorial(n - 1);
}

2. Aggregate() is one of the most powerful LINQ extension method, like Select() and Where(). We can use it to replace the Sum(), Min(). Max(), Avg() functionality, or to change it by implementing addition context:

    var numbers = new[]{3, 2, 6, 4, 9, 5, 7};
    var avg = numbers.Aggregate(0.0, (result, x) => result + x, response => (double)response/(double)numbers.Count());
    var min = numbers.Aggregate((result, x) => (result < x)? result: x);

3. More complex usage of extension methods:

    var path = @“c:\path-to-folder”;

    string[] txtFiles = Directory.GetFiles(path).Where(f => f.EndsWith(“.txt”)).ToArray<string>();
    var output = txtFiles.Select(f => File.ReadAllText(f, Encoding.Default)).Aggregate<string>((result, content) => result + content);

    File.WriteAllText(path + “summary.txt”, output, Encoding.Default);

    Console.WriteLine(“Text files merged into: {0}”, output); //or other log info

iframes are used a lot to include complete pages. When those pages are hosted on another domain you get problems with cross side scripting and stuff. There are ways to fix this.

Frames were used to divide your page into multiple parts (for example, a navigation menu on the left). Using them is no longer recommended.

Working with Eclipse can be difficult at times, probably when debugging and designing layouts Eclipse sometimes get stuck and we have to restart Eclipse from time to time. Also you get problems with emulators.

Android studio was released very recently and this IDE is not yet heavily used by developers. Therefore, it may contain certain bugs.

This describes the difference between android android studio and eclipse project structure: Android Studio Project Structure (v.s. Eclipse Project Structure)

This teaches you how to use the android studio: http://www.infinum.co/the-capsized-eight/articles/android-studio-vs-eclipse-1-0

1. .NET is the Ecosystem based on c# language
2. .NET Standard is Standard (in other words, specification) of .NET Ecosystem .

.Net Core Class Library is built upon the .Net Standard. .NET Standard you can make only class-library project that cannot be executed standalone and should be referenced by another .NET Core or .NET Framework executable project.If you want to implement a library that is portable to the .Net Framework, .Net Core and Xamarin, choose a .Net Standard Library

3. .NET Framework is a framework based on .NET and it supports Windows and Web applications

(You can make executable project (like Console application, or ASP.NET application) with .NET Framework

4. ASP.NET is a web application development technology which is built over the .NET Framework
5. .NET Core also a framework based on .NET.

It is the new open-source and cross-platform framework to build applications for all operating system including Windows, Mac, and Linux.

6. Xamarin is a framework to develop a cross platform mobile application(iOS, Android, and Windows Mobile) using C#

Implementation support of .NET Standard[blue] and minimum viable platform for full support of .NET Standard (latest: [https://docs.microsoft.com/en-us/dotnet/standard/net-standard#net-implementation-support])

All other answers, and mainly about list comprehension, are great. But just to explain your error:

strip_list = []
for lengths in range(1,20):
    strip_list.append(0) #longest word in the text file is 20 characters long
for a in lines:
    strip_list.append(lines[a].strip())

a is a member of your list, not an index. What you could write is this:

[...]
for a in lines:
    strip_list.append(a.strip())

Another important comment: you can create an empty list this way:

strip_list = [0] * 20

But this is not so useful, as .append appends stuff to your list. In your case, it's not useful to create a list with defaut values, as you'll build it item per item when appending stripped strings.

So your code should be like:

strip_list = []
for a in lines:
    strip_list.append(a.strip())

But, for sure, the best one is this one, as this is exactly the same thing:

stripped = [line.strip() for line in lines]

In case you have something more complicated than just a .strip, put this in a function, and do the same. That's the most readable way to work with lists.

Yes, you are correct. If you are using a jQuery plugin, do not put the code in the controller. Instead create a directive and put the code that you would normally have inside the link function of the directive.

There are a couple of points in the documentation that you could take a look at. You can find them here:
Common Pitfalls

Using controllers correctly

Ensure that when you are referencing the script in your view, you refer it last - after the angularjs library, controllers, services and filters are referenced.

EDIT: Rather than using $(element), you can make use of angular.element(element) when using AngularJS with jQuery

Trying to compress a PDF I made with 400ppi tiffs, mostly 8-bit, a few 24-bit, with PackBits compression, using tiff2pdf compressed with Zip/Deflate. One problem I had with every one of these methods: none of the above methods preserved the bookmarks TOC that I painstakingly manually created in Acrobat Pro X. Not even the recommended ebook setting for gs. Sure, I could just open a copy of the original with the TOC intact and do a Replace pages but unfortunately, none of these methods did a satisfactory job to begin with. Either they reduced the size so much that the quality was unacceptably pixellated, or they didn't reduce the size at all and in one case actually increased it despite quality loss.

Look up \enlargethispage in some LaTeX reference.

Just add this to your code Controller

return response()->json(compact('token'))->header("Access-Control-Allow-Origin",  "*");

This is part of the Generics mechanism, where the where keyword add constraints to what types must implement in order to be used as type parameters.

pip is run from the command line, not the Python interpreter. It is a program that installs modules, so you can use them from Python. Once you have installed the module, then you can open the Python shell and do import selenium.

The Python shell is not a command line, it is an interactive interpreter. You type Python code into it, not commands.

They both return the same thing, as noted in the documentation you linked; an HttpSession object.

You can also look at a concrete implementation (e.g. Tomcat) and see what it's actually doing: Request.java class. In this case, basically they both call:

Session session = doGetSession(true);

Anything wrong with a one-liner?

$ perl -pi.bak -e 's/blue/red/g' *_classification.dat

Explanation

• -p processes, then prints <> line by line
• -i activates in-place editing. Files are backed up using the .bak extension
• The regex substitution acts on the implicit variable, which are the contents of the file, line-by-line

I got the same issue. My solution was a foreach of radio buttons, with the image at the right of it. Since you can only choose a single option at radio, it works (like) a select.

Worket well for me. Hope it can help someone else.

I figured it out. Need to use echo in PHP instead of return.

<?php 
  $output = some_function();
  echo $output;
?> 

And the jQ:

success: function(data) {
  doSomething(data);
}

This is because $pjs is an one-element-array of objects, so first you should access the array element, which is an object and then access its attributes.

echo $pjs[0]->player_name;

Actually dump result that you pasted tells it very clearly.

I will not be as arrogant to claim that this is a standard so I will use the "I prefer" form.

I prefer terse response (when requesting a list of /articles I want a JSON array of articles).

In my designs I use HTTP for status report, a 200 returns just the payload.

400 returns a message of what was wrong with request:

{"message" : "Missing parameter: 'param'"}

Return 404 if the model/controler/URI doesn't exist

If there was error with processing on my side, I return 501 with a message:

{"message" : "Could not connect to data store."}

From what I've seen quite a few REST-ish frameworks tend to be along these lines.

Rationale:

JSON is supposed to be a payload format, it's not a session protocol. The whole idea of verbose session-ish payloads comes from the XML/SOAP world and various misguided choices that created those bloated designs. After we realized all of it was a massive headache, the whole point of REST/JSON was to KISS it, and adhere to HTTP. I don't think that there is anything remotely standard in either JSend and especially not with the more verbose among them. XHR will react to HTTP response, if you use jQuery for your AJAX (like most do) you can use try/catch and done()/fail() callbacks to capture errors. I can't see how encapsulating status reports in JSON is any more useful than that.

You can do that using Requestify, a very simple and cool HTTP client I wrote for nodeJS, it support easy use of cookies and it also supports caching.

To perform a request with a cookie attached just do the following:

var requestify = require('requestify');
requestify.post('http://google.com', {}, {
    cookies: {
        sessionCookie: 'session-cookie-data'   
    }
});

int (*x)() is not a pointer to member function. A pointer to member function is written like this: int (A::*x)(void) = &A::f;.

You need to set a few extra flags so that curl sends the data as JSON.

command

$ curl -H "Content-Type: application/json" \
       -X POST \
       -d '{"JSON": "HERE"}' \
       http://localhost:3000/api/url

flags

• -H: custom header, next argument is expected to be header
• -X: custom HTTP verb, next argument is expected to be verb
• -d: sends the next argument as data in an HTTP POST request

resources

• cURL manpage
• cURL examples

For to use looping get all arguments and in pure batch:

Obs: For using without: ?*&<>

@echo off && setlocal EnableDelayedExpansion

 for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && (
     call set "_arg_[!_cnt!]=!_arg_!" && for /l %%l in (!_cnt! 1 !_cnt!
     )do echo/ The argument n:%%l is: !_arg_[%%l]!
 )

goto :eof 

Your code is ready to do something with the argument number where it needs, like...

 @echo off && setlocal EnableDelayedExpansion

 for %%Z in (%*)do set "_arg_=%%Z" && set/a "_cnt+=1+0" && call set "_arg_[!_cnt!]=!_arg_!"
 
 fake-command /u !_arg_[1]! /p !_arg_[2]! > test-log.txt
 

You can think of a static member function as one that exists without the need for an object to exist. For example, the Integer.parseInt() method from the Integer class is static. When you need to use it, you don't need to create a new Integer object, you simply call it. The same thing for main(). If you need to call a non-static member from it, simply put your main code in a class and then from main create a new object of your newly created class.

It was mentioned only briefly once, so I'd like to call out the docx4j library, as I've had more success with docx4j than anything else. Apache POI's support for Word documents isn't very good. Also, unlike Aspose.Words, docx4j is an open source library.

The only drawback is with docx4j you have to create Office Open XML (docx) format documents rather than OLE2-based (doc) format documents. This is the default format for Word 2007, but Word 2003 and earlier users will need to install a compatibility pack.

Screen's Background Color

(As of Xcode Version 12)

I'm not sure if the original poster meant the background color of the entire screen or of individual views. So I'll just add this answer which is to set the entire screen's background color.

Using ZStack

var body: some View {
    ZStack {
            Color.purple
                .ignoresSafeArea()
            
            // Your other content here
            // Other layers will respect the safe area edges
    }
}

I added .ignoresSafeArea() otherwise, it will stop at safe area margins.

Using Overlay Modifier

var body: some View {
    Color.purple
        .ignoresSafeArea(.vertical) // Ignore just for the color
        .overlay(

In addition to the above comments, I would like to add few points about Views.

1. Views can be used to hide complexity. Imagine a scenario where 5 people are working on a project but only one of them is too good with database stuff like complex joins. In such scenario, he can create Views which can be easily queried by other team members as they are querying any single table.
2. Security can be easily implemented by Views. Suppose we a Table Employee which contains sensitive columns like Salary, SSN number. These columns are not supposed to be visible to the users who are not authorized to view them. In such case, we can create a View selecting the columns in a table which doesn't require any authorization like Name, Age etc, without exposing sensitive columns (like Salary etc. we mentioned before). Now we can remove permission to directly query the table Employee and just keep the read permission on the View. In this way, we can implement security using Views.

According to the documentation:

If this abstract pathname does not denote a directory, then this method returns null.

So you should check if listFiles is null and only continue if it's not

boolean deleteDirectory(File path) {
    if(path.exists()) {
        File[] files = path.listFiles();
        if (files == null) {
            return false;
        }
        for (File file : files) {
            if (file.isDirectory()) {
                deleteDirectory(file);
            } else {
                boolean wasSuccessful = file.delete();
                if (wasSuccessful) {
                    Log.i("Deleted ", "successfully");
                }
            }
        }
    }
    return(path.delete());
}

You can assign int to char directly.

int a = 65;
char c = a;
printf("%c", c);

In fact this will also work.

printf("%c", a);  // assuming a is in valid range

It will overflow and wrap around to Long.MIN_VALUE.

Its not too likely though. Even if you increment 1,000,000 times per second it will take about 300,000 years to overflow.

You should use the following code :

Class2 cls2 = new Class2();
cls2.UpdateEmployee();

In case you don't want to create a new instance to call the method, you can decalre the method as static and then you can just call Class2.UpdateEmployee().

you can do something for a list object,

data("mtcars")
rownames(mtcars)
data <- list(mtcars ,mtcars, mtcars, mtcars);data

out1 <- NULL 
for(i in seq_along(data)) { 
  out1[[i]] <- data[[i]][rownames(data[[i]]) != "Volvo 142E", ] } 
out1

Or a data frame,

data("mtcars")
df <- mtcars
out1 <- NULL 
for(i in 1:nrow(df)) {
  row <- rownames(df[i,])
  # do stuff with row
  out1 <- df[rownames(df) != "Volvo 142E",]
  
}
out1 

This works for me...

1. The height needed to show all entries, or
2. The height needed to show x entries (with scrollbars to see remaining), where x is
   • 20 in Firefox & Chrome
   • 30 in IE 6, 7, 8
   • 16 for Opera 10
   • 14 for Opera 11
   • 22 for Safari 4
   • 18 for Safari 5
   • 11 in IE 5.0, 5.5
3. In IE/Edge, if there are no options, a stupidly high list of 11 blanks entries.

You can use QPalette, however you must set setAutoFillBackground(true); to enable background color

QPalette sample_palette;
sample_palette.setColor(QPalette::Window, Qt::white);
sample_palette.setColor(QPalette::WindowText, Qt::blue);

sample_label->setAutoFillBackground(true);
sample_label->setPalette(sample_palette);
sample_label->setText("What ever text");

It works fine on Windows and Ubuntu, I haven't played with any other OS.

Note: Please see QPalette, color role section for more details

Aside from @JsonIgnore, there are a couple of other possibilities:

• Use JSON Views to filter out fields conditionally (by default, not used for deserialization; in 2.0 will be available but you can use different view on serialization, deserialization)
• @JsonIgnoreProperties on class may be useful

Something that is not relevant for the OP, but maybe for someone else in the future:

For pixels (px), if the value is "0", the unit can be omitted: right: 0 and right: 0px both work.

However I noticed that in Firefox and Chrome this is not the case for the seconds unit (s). While transition: right 1s ease 0s works, transition: right 1s ease 0 (missing unit s for last value transition-delay) does not (it does work in Edge however).

In the following example, you'll see that right works for both 0px and 0, but transition only works for 0s and it doesn't work with 0.

(Mar 2017) The accepted answer is not the best solution. It relies on manual translation using Apps Script, and the code may not be resilient, requiring maintenance. If your legacy system autogenerates CSV files, it's best they go into another folder for temporary processing (importing [uploading to Google Drive & converting] to Google Sheets files).

My thought is to let the Drive API do all the heavy-lifting. The Google Drive API team released v3 at the end of 2015, and in that release, insert() changed names to create() so as to better reflect the file operation. There's also no more convert flag -- you just specify MIMEtypes... imagine that!

The documentation has also been improved: there's now a special guide devoted to uploads (simple, multipart, and resumable) that comes with sample code in Java, Python, PHP, C#/.NET, Ruby, JavaScript/Node.js, and iOS/Obj-C that imports CSV files into Google Sheets format as desired.

Below is one alternate Python solution for short files ("simple upload") where you don't need the apiclient.http.MediaFileUpload class. This snippet assumes your auth code works where your service endpoint is DRIVE with a minimum auth scope of https://www.googleapis.com/auth/drive.file.

# filenames & MIMEtypes
DST_FILENAME = 'inventory'
SRC_FILENAME = DST_FILENAME + '.csv'
SHT_MIMETYPE = 'application/vnd.google-apps.spreadsheet'
CSV_MIMETYPE = 'text/csv'

# Import CSV file to Google Drive as a Google Sheets file
METADATA = {'name': DST_FILENAME, 'mimeType': SHT_MIMETYPE}
rsp = DRIVE.files().create(body=METADATA, media_body=SRC_FILENAME).execute()
if rsp:
    print('Imported %r to %r (as %s)' % (SRC_FILENAME, DST_FILENAME, rsp['mimeType']))

Better yet, rather than uploading to My Drive, you'd upload to one (or more) specific folder(s), meaning you'd add the parent folder ID(s) to METADATA. (Also see the code sample on this page.) Finally, there's no native .gsheet "file" -- that file just has a link to the online Sheet, so what's above is what you want to do.

If not using Python, you can use the snippet above as pseudocode to port to your system language. Regardless, there's much less code to maintain because there's no CSV parsing. The only thing remaining is to blow away the CSV file temp folder your legacy system wrote to.

I used the http://www.javadecompilers.com but in some classes it gives you the message "could not load this classes..."

INSTEAD download Android Studio, navigate to the folder containing the java class file and double click it. The code will show in the right pane and I guess you can copy it an save it as a java file from there

An XSD is included with EntLib 5, and is installed in the Visual Studio schema directory. In my case, it could be found at:

"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas\EnterpriseLibrary.Configuration.xsd"

CONTEXT

• Visual Studio 2010
• Enterprise Library 5

STEPS TO REMOVE THE WARNINGS

1. open app.config in your Visual Studio project
2. right click in the XML Document editor, select "Properties"
3. add the fully qualified path to the "EnterpriseLibrary.Configuration.xsd"

ASIDE

It is worth repeating that these "Error List" "Messages" ("Could not find schema information for the element") are only visible when you open the app.config file. If you "Close All Documents" and compile... no messages will be reported.

SELECT c.Name 
FROM sys.columns c
JOIN sys.objects o ON o.object_id = c.object_id
WHERE o.object_id = OBJECT_ID('TABLE_NAME')
ORDER BY c.Name

Just go to References and add "System.IO.Compression.FileSystem".

If you are replacing the same amount of characters and after carefully reading “In-place” editing of files...

You can also use the redirection operator <> to open the file to read and write:

sed 's/foo/bar/g' file 1<> file

See it live:

$ cat file
hello
i am here                           # see "here"
$ sed 's/here/away/' file 1<> file  # Run the `sed` command
$ cat file
hello
i am away                           # this line is changed now

From Bash Reference Manual ? 3.6.10 Opening File Descriptors for Reading and Writing:

The redirection operator

[n]<>word

causes the file whose name is the expansion of word to be opened for both reading and writing on file descriptor n, or on file descriptor 0 if n is not specified. If the file does not exist, it is created.

To add a bit more value to all the other answer's to this question, one should invest a few minutes in the question: What is the output of the following code?

#include <iostream>
void throw_exception() throw(const char *)
{
    throw 10;
}
void my_unexpected(){
    std::cout << "well - this was unexpected" << std::endl;
}
int main(int argc, char **argv){
    std::set_unexpected(my_unexpected);
    try{
        throw_exception();
    }catch(int x){
        std::cout << "catch int: " << x << std::endl;
    }catch(...){
        std::cout << "catch ..." << std::endl;
    }
}

Answer: As noted here, the program calls std::terminate() and thus none of the exception handlers will get called.

Details: First my_unexpected() function is called, but since it doesn't re-throw a matching exception type for the throw_exception() function prototype, in the end, std::terminate() is called. So the full output looks like this:

user@user:~/tmp$ g++ -o except.test except.test.cpp
user@user:~/tmp$ ./except.test
well - this was unexpected
terminate called after throwing an instance of 'int'
Aborted (core dumped)

Also, know that there is a special case where return await is correct and important : (using try/catch)

Are there performance concerns with `return await`?

All of the provided answers are more complicated than necessary. Assuming you are building a jar file, all you need to do is add a <jar.finalName> tag to your <properties> section:

<properties>
    <jar.finalName>${project.name}</jar.finalName>
</properties>

This will generate a jar:

project/target/${project.name}.jar

This is in the documentation - note the User Property:

finalName:
Name of the generated JAR.
Type: java.lang.String
Required: No
User Property: jar.finalName
Default: ${project.build.finalName}

Command Line Usage

You should also be able to use this option on the command line with:

mvn -Djar.finalName=myCustomName ...

You should get myCustomName.jar, although I haven't tested this.

Since destroy kind of destroys "everything", a cheap and simple solution when all you really want is to just "reset the data". Resetting your datasets to an empty array will work perfectly fine as well. So, if you have a dataset with labels, and an axis on each side:

window.myLine2.data.labels = [];
window.myLine2.data.datasets[0].data = [];
window.myLine2.data.datasets[1].data = [];

After this, you can simply call:

window.myLine2.data.labels.push(x);
window.myLine2.data.datasets[0].data.push(y);

or, depending whether you're using a 2d dataset:

window.myLine2.data.datasets[0].data.push({ x: x, y: y});

It'll be a lot more lightweight than completely destroying your whole chart/dataset, and rebuilding everything.

Use a regular for loop and format the index to be used in the selector.

var array = [];
for (var i = 0; i < 4; i++) {
    var selector = '' + i;
    if (selector.length == 1)
        selector = '0' + selector;
    selector = '#event' + selector;
    array.push($(selector, response).html());
}

Update with Angular 7.x.x, encounter the same issue in one of my modules.

If it lies in your independent module, add these extra modules:

import { CommonModule } from "@angular/common";
import { FormsModule } from "@angular/forms";

@NgModule({
  imports: [CommonModule, FormsModule], // the order can be random now;
  ...
})

If it lies in your app.module.ts, add these modules:

import { BrowserModule } from '@angular/platform-browser';
import { FormsModule } from '@angular/forms';

@NgModule({
  imports:      [ FormsModule, BrowserModule ], // order can be random now
  ...
})

You can use union method for sets: set.union(other_set)

Note that it returns a new set i.e it doesn't modify itself.

With numpy 1.3 or svn you can do this

In [1]: a = arange(10000.).reshape(100,100)

In [3]: isnan(a.max())
Out[3]: False

In [4]: a[50,50] = nan

In [5]: isnan(a.max())
Out[5]: True

In [6]: timeit isnan(a.max())
10000 loops, best of 3: 66.3 µs per loop

The treatment of nans in comparisons was not consistent in earlier versions.

If you don't see the Active Directory, it's because you did not install AD LS Users and Computer Feature. Go to Manage - Add Roles & Features. Within Add Roles and Features Wizard, on Features tab, select Remote Server Administration Tools, select - Role Admininistration Tools - Select AD DS and DF LDS Tools.

After that, you can see the PS Active Directory package.

Building on icova's answer, here's the code so you can use a custom HTML5 validation message:

$(function() {
    var requiredCheckboxes = $(':checkbox[required]');
    requiredCheckboxes.change(function() {
        if (requiredCheckboxes.is(':checked')) {requiredCheckboxes.removeAttr('required');}
        else {requiredCheckboxes.attr('required', 'required');}
    });
    $("input").each(function() {
        $(this).on('invalid', function(e) {
            e.target.setCustomValidity('');
            if (!e.target.validity.valid) {
                e.target.setCustomValidity('Please, select at least one of these options');
            }
        }).on('input, click', function(e) {e.target.setCustomValidity('');});
    });
});

are you sure you told it to expect the exception?

for newer junit (>= 4.7), you can use something like (from here)

@Rule
public ExpectedException exception = ExpectedException.none();

@Test
public void testRodneCisloRok(){
    exception.expect(IllegalArgumentException.class);
    exception.expectMessage("error1");
    new RodneCislo("891415",dopocitej("891415"));
}

and for older junit, this:

@Test(expected = ArithmeticException.class)  
public void divisionWithException() {  
  int i = 1/0;

What you're asking is not possible. There is no mechanism in .Net that would set all references to some object to null.

And I think that the fact that you're trying to do this indicates some sort of design problem. You should probably think about the underlying problem and solve it in another way (the other answers here suggest some options).

You Can Use This code

((AppCompatActivity) getActivity()).getSupportFragmentManager().beginTransaction().replace(R.id.YourFrameLayout, new YourFragment()).commit();

or You Can This Use Code

YourFragment fragments=(YourFragment) getSupportFragmentManager().findFragmentById(R.id.FrameLayout);

        if (fragments==null) {
            getSupportFragmentManager().beginTransaction().replace(R.id.FrameLayout, new Fragment_News()).commit();
        }

A Seq is an Iterable that has a defined order of elements. Sequences provide a method apply() for indexing, ranging from 0 up to the length of the sequence. Seq has many subclasses including Queue, Range, List, Stack, and LinkedList.

A List is a Seq that is implemented as an immutable linked list. It's best used in cases with last-in first-out (LIFO) access patterns.

Here is the complete collection class hierarchy from the Scala FAQ:

Another option would be using flexbox.

While it's not supported by IE8 and IE9, you could consider:

• Not minding about those old IE versions
• Providing a fallback
• Using a polyfill

Despite some additional browser-specific style prefixing would be necessary for full cross-browser support, you can see the basic usage either on this fiddle and on the following snippet:

You can use GCD (in the example with a 10 second delay):

Swift 2

let triggerTime = (Int64(NSEC_PER_SEC) * 10)
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, triggerTime), dispatch_get_main_queue(), { () -> Void in
    self.functionToCall()
})

Swift 3 and Swift 4

DispatchQueue.main.asyncAfter(deadline: .now() + 10.0, execute: {
    self.functionToCall()
})

Swift 5 or Later

 DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
        //call any function
    }

The ".a" at the end of your DLL files is a problem, and those are there because you didn't use CMAKE to build OpenCV 2.0. Additionally you do not link to the DLL files, you link to the library files, and again, the reason you do not see the correct library files is because you didn't use CMAKE to build OpenCV 2.0. If you want to use OpenCV 2.0 you must build it for it to work correctly in Visual Studio. If you do not want to build it then I would suggest downgrading to OpenCV 1.1pre, it comes pre-built and is much more forgiving in Visual Studio.

Another option (and the one I would recommend) is to abandon OpenCV and go with EmguCV. I have been playing with OpenCV for about a year and things got much easier when I switched to EmguCV because EmguCV works with .NET, so you can use a language like C# that does not come with all the C++ baggage of pointers, header files, and memory allocation problem.

And as for the question of 64bit vs. 32bit, OpenCV does not officially support 64bit. To be on the safe side open your project properties and change the "Platform Target" under the "Build" tab from "Any CPU" to "X86". This should be done any time you do anything with OpenCV, even if you are using a wrapper like EmguCV.

A simple way of catching thread's exception and communicating back to the caller method could be by passing dictionary or a list to worker method.

Example (passing dictionary to worker method):

import threading

def my_method(throw_me):
    raise Exception(throw_me)

def worker(shared_obj, *args, **kwargs):
    try:
        shared_obj['target'](*args, **kwargs)
    except Exception as err:
        shared_obj['err'] = err

shared_obj = {'err':'', 'target': my_method}
throw_me = "Test"

th = threading.Thread(target=worker, args=(shared_obj, throw_me), kwargs={})
th.start()
th.join()

if shared_obj['err']:
    print(">>%s" % shared_obj['err'])

This is the solution I ended up using. I wanted an inline solution, and this so far seems to work great:

<textarea onkeyup="$(this).css('height', 'auto').css('height', this.scrollHeight + this.offsetHeight - this.clientHeight);"></textarea>

Copy the contents of the PATH settings to a notepad and check if the location for the 1.4.2 comes before that of the 7. If so, remove the path to 1.4.2 in the PATH setting and save it.

After saving and applying "Environment Variables" close and reopen the cmd line. In XP the path does no get reflected in already running programs.

One of the reasons of this problem might be "Build Active Architecture Only". You need set to true.

In case you don't want to set fixed width to anything

The solution below allows you to have table cell content that is long, but must not affect the width of the parent table, nor the height of the parent row. For example where you want to have a table with width:100% that still applies auto-size feature to all other cells. Useful in data grids with "Notes" or "Comment" column or something.

Add these 3 rules to your CSS:

.text-overflow-dynamic-container {
    position: relative;
    max-width: 100%;
    padding: 0 !important;
    display: -webkit-flex;
    display: -moz-flex;
    display: flex;
    vertical-align: text-bottom !important;
}
.text-overflow-dynamic-ellipsis {
    position: absolute;
    white-space: nowrap;
    overflow-y: visible;
    overflow-x: hidden;
    text-overflow: ellipsis;
    -ms-text-overflow: ellipsis;
    -o-text-overflow: ellipsis;
    max-width: 100%;
    min-width: 0;
    width:100%;
    top: 0;
    left: 0;
}
.text-overflow-dynamic-container:after,
.text-overflow-dynamic-ellipsis:after {
    content: '-';
    display: inline;
    visibility: hidden;
    width: 0;
}

Format HTML like this in any table cell you want dynamic text overflow:

<td>
  <span class="text-overflow-dynamic-container">
    <span class="text-overflow-dynamic-ellipsis" title="...your text again for usability...">
      //...your long text here...
    </span>
  </span>
</td>

Additionally apply desired min-width (or none at all) to the table cell.

Of course the fiddle: https://jsfiddle.net/9wycg99v/23/

With n being the line number:

• ng: Jump to line number n. Default is the start of the file.
• nG: Jump to line number n. Default is the end of the file.

So to go to line number 320123, you would type 320123g.

Copy-pasted straight from Wikipedia.

Call me simple but I just declared a Variant and split the responsetext from my REST GET on the quote comma quote between each item, then got the value I wanted by looking for the last quote with InStrRev. I'm sure that's not as elegant as some of the other suggestions but it works for me.

         varLines = Split(.responsetext, """,""")
        strType = Mid(varLines(8), InStrRev(varLines(8), """") + 1)

I found this method to be quite useful. However it will convert your date/time format to just date but never the less it does the job for what I need it for. (I just needed to display the date on a report, the time was irrelevant).

CAST(start_date AS DATE)

UPDATE

(Bear in mind I'm a trainee ;))

I figured an easier way to do this IF YOU'RE USING SSRS.

It's easier to actually change the textbox properties where the field is located in the report. Right click field>Number>Date and select the appropriate format!

you can write .WorkbookConnection.Delete after .Refresh BackgroundQuery:=False this will delete text file external connection.

Use something like this to update your tomcat users.

<role rolename="manager-gui"/>
<user username="admin" password="admin" roles="manager-gui"/>

Tomcat users file is located inside conf folder of tomcat installation. To find the path of catalina_base you can use the command: ps aux | grep catalina You can find one of the values -Dcatalina.base=/usr/local/Cellar/tomcat/9.0.37/libexec

Most Important:

Don't forget to remove the comment lines from the tomcat-users.xml just before the start of the roles. <!-- -->

Well, I have a tricky method for this job. The idea is as follow-

Make some invisible HTML tags like <label>, <p>, <input> etc. in HTML body and make a pattern in tag id, for example, use list index in tag id and list value at tag class name.

Here I have two lists maintenance_next[] and maintenance_block_time[] of the same length. I want to pass these two list's data to javascript using the flask. So I take some invisible label tag and set its tag name is a pattern of list index and set its class name as value at index.

{% for i in range(maintenance_next|length): %}_x000D_
<label id="maintenance_next_{{i}}" name="{{maintenance_next[i]}}" style="display: none;"></label>_x000D_
<label id="maintenance_block_time_{{i}}" name="{{maintenance_block_time[i]}}" style="display: none;"></label>_x000D_
{% endfor%}

After this, I retrieve the data in javascript using some simple javascript operation.

<script>_x000D_
var total_len = {{ total_len }};_x000D_
_x000D_
for (var i = 0; i < total_len; i++) {_x000D_
    var tm1 = document.getElementById("maintenance_next_" + i).getAttribute("name");_x000D_
    var tm2 = document.getElementById("maintenance_block_time_" + i).getAttribute("name");_x000D_
    _x000D_
    //Do what you need to do with tm1 and tm2._x000D_
    _x000D_
    console.log(tm1);_x000D_
    console.log(tm2);_x000D_
}_x000D_
</script>

If you want to completely remove commits from history, you can also do a dump of the repo at a specific revision, then import that dump. Specifically:

svnrdump dump -r 1:<rev> <url> > filename.dump

The svnrdump command performs the same function as svnadmin dump but works on a remote repo.

Next just import the dump file into your repo of choice. This was tested to worked well on Beanstalk.

Also, while not a pure Python solution, if you're using IPython (as you probably should anyway), you can do:

%run /path/to/filename.py

Which is equally easy.

If you are manually assembling the XML string use var.ToUniversalTime().ToString("yyyy-MM-dd'T'HH:mm:ss.fffffffZ")); That will output the official XML Date Time format. But you don't have to worry about format if you use the built-in serialization methods.

Edit: please see my other answer, as you probably don't need this now.

As you said, in API levels 11+ a HTML5VideoFullScreen$VideoSurfaceView is passed. But I don't think you are right when you say that "it doens't have a MediaPlayer".

This is the way to reach the MediaPlayer instance from the HTML5VideoFullScreen$VideoSurfaceView instance using reflection:

@SuppressWarnings("rawtypes")
Class c1 = Class.forName("android.webkit.HTML5VideoFullScreen$VideoSurfaceView");
Field f1 = c1.getDeclaredField("this$0");
f1.setAccessible(true);

@SuppressWarnings("rawtypes")
Class c2 = f1.getType().getSuperclass();
Field f2 = c2.getDeclaredField("mPlayer");
f2.setAccessible(true);

Object ___html5VideoViewInstance = f1.get(focusedChild); // Look at the code in my other answer to this same question to see whats focusedChild

Object ___mpInstance = f2.get(___html5VideoViewInstance); // This is the MediaPlayer instance.

So, now you could set the onCompletion listener of the MediaPlayer instance like this:

OnCompletionListener ocl = new OnCompletionListener()
{
    @Override
    public void onCompletion(MediaPlayer mp)
    {
        // Do stuff
    }
};

Method m1 = f2.getType().getMethod("setOnCompletionListener", new Class[] { Class.forName("android.media.MediaPlayer$OnCompletionListener") });
m1.invoke(___mpInstance, ocl);

The code doesn't fail but I'm not completely sure if that onCompletion listener will really be called or if it could be useful to your situation. But just in case someone would like to try it.

var select = document.getElementById('/*id attribute of your select here*/');
for (var option in select){
    select.remove(option);
}

Try changing every occurence of .\Release into .\x64\Release in the x64 properties. At least this worked for me...

Oh I figured this out, please ignore unless you have the same problem i did in which case:

$prevmonth = date("M Y",mktime(0,0,0,date("m")-1,1,date("Y")));

You have checked that R is actually able to find the file, e.g. file.exists("C:/AB_DNA_Tag_Numbers.xlsx") ? – Ben Bolker Aug 14 '11 at 23:05

Above comment should've solved your problem:

require("xlsx")
read.xlsx("filepath/filename.xlsx",1) 

should work fine after that.

Use the datetime method and the operator < and its kin.

>>> from datetime import datetime, timedelta
>>> past = datetime.now() - timedelta(days=1)
>>> present = datetime.now()
>>> past < present
True
>>> datetime(3000, 1, 1) < present
False
>>> present - datetime(2000, 4, 4)
datetime.timedelta(4242, 75703, 762105)

Change

vote = input('Enter the name of the player you wish to vote for')

to

vote = int(input('Enter the name of the player you wish to vote for'))

You are getting the input from the console as a string, so you must cast that input string to an int object in order to do numerical operations.

I added dataType as json and made the response as json:

PHP

echo json_encode(array('success'=>$res)); //send the response as json **use this instead of echo $res in your php file**

JavaScript

  var ajaxSubmit = function(formE1) {

        var password = $.trim($('#employee_password').val());    
        $.ajax({
            type: "POST",
            async: "false",
            url: "checkpass.php",
            data: "password="+password,
            dataType:'json',  //added this so the response is in json
            success: function(result) {
                var arr=result.success;
                if(arr == "Successful")
                {    return true;
                }
                else
                {    return false;
                }
            }
        });

  return false
}

Another more manual option to get it:

.nuget\nuget.exe install Newtonsoft.Json -Version 4.0.5

Another, very pragmatic reason, to prefer composition over inheritance has to do with your domain model, and mapping it to a relational database. It's really hard to map inheritance to the SQL model (you end up with all sorts of hacky workarounds, like creating columns that aren't always used, using views, etc). Some ORMLs try to deal with this, but it always gets complicated quickly. Composition can be easily modeled through a foreign-key relationship between two tables, but inheritance is much harder.

This issue has been fixed in m2e 1.5.0 which is available for Eclipse Kepler (4.3) and Luna (4.4)

Please see https://bugs.eclipse.org/bugs/show_bug.cgi?id=374332#c14

The problem is caused by the fact that STS (the Spring IDE/Eclipse), as well Eclipse and other Eclipse based IDE's, use the m2e(clipse) plugin but that eclipse:eclipse has been probably been run on the project. When m2e encounters a "var" .classpath entry, it throws this error.

The update sites are specified at the following url:
http://eclipse.org/m2e/m2e-downloads.html

If you can't use m2e 1.5.0 for any reason, then :

1. Disable the maven nature for the project (via the right-click menu)

2. Run mvn eclipse:clean (while your project is open in STS/eclipse). Depending on the timing, you might need to do a refresh or two on the project before re-enabling the maven nature. You should be able to see that your project has lost it's Maven nature. (The eclipse:clean goal just deletes the .project, .classpath and .settings/ files/directories. You can also just remove those files (again while the project is open) instead of running mvn eclipse:clean.)

3. Re-enable the maven nature.
   (Most of the time, this can be done by right-clicking on the project in question in the package explorer pane, and then choosing 'Configure'-> 'Convert to Maven Project')

First you should use print_r($_FILES) to debug, and see what it contains. :

your uploads.php would look like:

//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);

//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];


//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
    //Tells you if its all ok
    echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
    // Connects to your Database
    mysql_connect("localhost", "root", "") or die(mysql_error()) ;
    mysql_select_db("altabotanikk") or die(mysql_error()) ;

    //Writes the information to the database
    mysql_query("INSERT INTO picture (Filename,Description)
    VALUES ('$Filename', '$Description')") ;
} else {
    //Gives and error if its not
    echo "Sorry, there was a problem uploading your file.";
}



?>

EDIT: Since this is old post, currently it is strongly recommended to use either mysqli or pdo instead mysql_ functions in php

It can be done and with rather simple php if this is your button

<input type="submit" name="submit>

and this is your php code

if(isset($_POST["submit"])) { php code here }

the code get's called when submit get's posted which happens when the button is clicked.

<?php

   $email = "someone@exa mple.com";

   else
      echo "E-mail is valid";

?>

The problem with the css3 scroll bars is that, interaction can only be performed on the content. we can't interact with the scroll bar on touch devices.

You need to get a list of all the keys, loop over them and add them to your map as shown in the example below:

    String s = "{menu:{\"1\":\"sql\", \"2\":\"android\", \"3\":\"mvc\"}}";
    JSONObject jObject  = new JSONObject(s);
    JSONObject  menu = jObject.getJSONObject("menu");

    Map<String,String> map = new HashMap<String,String>();
    Iterator iter = menu.keys();
    while(iter.hasNext()){
        String key = (String)iter.next();
        String value = menu.getString(key);
        map.put(key,value);
    }

The 4K limit you read about is for the entire cookie, including name, value, expiry date etc. If you want to support most browsers, I suggest keeping the name under 4000 bytes, and the overall cookie size under 4093 bytes.

One thing to be careful of: if the name is too big you cannot delete the cookie (at least in JavaScript). A cookie is deleted by updating it and setting it to expire. If the name is too big, say 4090 bytes, I found that I could not set an expiry date. I only looked into this out of interest, not that I plan to have a name that big.

To read more about it, here are the "Browser Cookie Limits" for common browsers.

While on the subject, if you want to support most browsers, then do not exceed 50 cookies per domain, and 4093 bytes per domain. That is, the size of all cookies should not exceed 4093 bytes.

This means you can have 1 cookie of 4093 bytes, or 2 cookies of 2045 bytes, etc.

I used to say 4095 bytes due to IE7, however now Mobile Safari comes in with 4096 bytes with a 3 byte overhead per cookie, so 4093 bytes max.

Here's a short code that might help.

    <yourJFrameName> main = new <yourJFrameName>();    

    main.setVisible(true);
    this.dispose();

where...

main.setVisible(true);

will run the JFrame again.

this.dispose();

will terminate the running window.

Since you mentioned Task Manager, I'll guess you're using Windows. Assuming you're running your script within the editor, if you aren't opposed to quitting the editor at the same time as quitting the running program, the keyboard shortcut to end a process is:

Alt + F4

(By which I mean press the 'Alt' and 'F4' keys on your keyboard simultaneously.)

Alternatively, as mentioned in other answers,

Ctrl + C

should also work, but will not quit the editor.
