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

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

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

could be generated from simple code:

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

public class TableCheckBox extends JFrame {

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

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

            private static final long serialVersionUID = 1L;

            /*@Override
            public Class getColumnClass(int column) {

            @Override
            public Class getColumnClass(int column) {
                switch (column) {
                    case 0:
                        return String.class;
                    case 1:

                        return Boolean.class;
                }
            }
        };
        table.setPreferredScrollableViewportSize(table.getPreferredSize());
        JScrollPane scrollPane = new JScrollPane(table);
        getContentPane().add(scrollPane);
    }

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

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

according to @jreback here https://github.com/conda/conda/issues/1166

conda config --set ssl_verify false 

will turn off this feature, e.g. here

I was able to fix this problem by setting font-size: 0 .

One thing to notice is the lack of any "Copyout" within git. That's because you already have a full copy in your local repo - your local repo being a clone of your chosen upstream repo. So you have effectively a personal checkout of everything, without putting some 'lock' on those files in the reference repo.

Git provides the SHA1 hash values as the mechanism for verifying that the copy you have of a file / directory tree / commit / repo is exactly the same as that used by whoever is able to declare things as "Master" within the hierarchy of trust. This avoids all those 'locks' that cause most SCM systems to choke (with the usual problems of private copies, big merges, and no real control or management of source code ;-) !

As you are using Homebrew the following command gives a better picture:

brew doctor

Output:

==> /usr/bin occurs before /usr/local/bin This means that system-provided programs will be used instead of those provided by Homebrew. This is an issue if you eg. brew installed Python.

Consider editing your .bash_profile to put: /usr/local/bin ahead of /usr/bin in your $PATH.

Python 2:

with open("datafile") as myfile:
    head = [next(myfile) for x in xrange(N)]
print head

Python 3:

with open("datafile") as myfile:
    head = [next(myfile) for x in range(N)]
print(head)

Here's another way (both Python 2 & 3):

from itertools import islice

with open("datafile") as myfile:
    head = list(islice(myfile, N))
print(head)

The sep='\t' can be use in many forms, for example if you want to read tab separated value: Example: I have a dataset tsv = tab separated value NOT comma separated value df = pd.read_csv('gapminder.tsv'). when you try to read this, it will give you an error because you have tab separated value not csv. so you need to give read csv a different parameter called sep='\t'.

Now you can read: df = pd.read_csv('gapminder.tsv, sep='\t'), with this you can read the it.

To make it fixed: Try this way,

New CKeditor doesn't have file manager included (CKFinder is payable). You can integrate free filemanager that is good looking and easy to implement in CKeditor.

http://labs.corefive.com/2009/10/30/an-open-file-manager-for-ckeditor-3-0/

You dowload it, copy it to your project. All instructions are there but you basically just put path to added filemanager index.html page in your code.

CKEDITOR.replace( 'meeting_notes',
{
startupFocus : true,
toolbar :
[
['ajaxsave'],
['Bold', 'Italic', 'Underline', '-', 'NumberedList', 'BulletedList', '-', 'Link', 'Unlink' ],
['Cut','Copy','Paste','PasteText'],
['Undo','Redo','-','RemoveFormat'],
['TextColor','BGColor'],
['Maximize', 'Image']
],
filebrowserUploadUrl : '/filemanager/index.html' // you must write path to filemanager where you have copied it.
});    

Most languages are supported (php, asp, MVC && aspx - ashx,...)).

It is best to use two DateTimePickers for the Job One will be the default for the date section and the second DateTimePicker is for the time portion. Format the second DateTimePicker as follows.

      timePortionDateTimePicker.Format = DateTimePickerFormat.Time;
      timePortionDateTimePicker.ShowUpDown = true;

The Two should look like this after you capture them

To get the DateTime from both these controls use the following code

DateTime myDate = datePortionDateTimePicker.Value.Date + 
                    timePortionDateTimePicker.Value.TimeOfDay; 

To assign the DateTime to both these controls use the following code

datePortionDateTimePicker.Value  = myDate.Date;  
timePortionDateTimePicker.Value  = myDate.TimeOfDay; 

We, the Javascript lovers, don't have to use Ruby (Jekyll or Octopress) to generate static pages in Github pages, we can use Node.js and Harp, for example:

These are the steps. Abstract:

1. Create a New Repository

2. Clone the Repository

   git clone https://github.com/your-github-user-name/your-github-user-name.github.io.git
   

3. Initialize a Harp app (locally):

   harp init _harp
   

make sure to name the folder with an underscore at the beginning; when you deploy to GitHub Pages, you don’t want your source files to be served.

4. Compile your Harp app

   harp compile _harp ./
   

5. Deploy to Gihub

   git add -A
   git commit -a -m "First Harp + Pages commit"
   git push origin master
   

And this is a cool tutorial with details about nice stuff like layouts, partials, Jade and Less.

This worked for me:

#inner {
    position: absolute;
    margin: 0 auto;
    left: 0;
    width: 7%;
    right: 0;
}

In this code, you determine the width of the element.

Starting another dispatch before your reducer is finished is an anti-pattern, because the state you received at the beginning of your reducer will not be the current application state anymore when your reducer finishes. But scheduling another dispatch from within a reducer is NOT an anti-pattern. In fact, that is what the Elm language does, and as you know Redux is an attempt to bring the Elm architecture to JavaScript.

Here is a middleware that will add the property asyncDispatch to all of your actions. When your reducer has finished and returned the new application state, asyncDispatch will trigger store.dispatch with whatever action you give to it.

// This middleware will just add the property "async dispatch" to all actions
const asyncDispatchMiddleware = store => next => action => {
  let syncActivityFinished = false;
  let actionQueue = [];

  function flushQueue() {
    actionQueue.forEach(a => store.dispatch(a)); // flush queue
    actionQueue = [];
  }

  function asyncDispatch(asyncAction) {
    actionQueue = actionQueue.concat([asyncAction]);

    if (syncActivityFinished) {
      flushQueue();
    }
  }

  const actionWithAsyncDispatch =
    Object.assign({}, action, { asyncDispatch });

  const res = next(actionWithAsyncDispatch);

  syncActivityFinished = true;
  flushQueue();

  return res;
};

Now your reducer can do this:

function reducer(state, action) {
  switch (action.type) {
    case "fetch-start":
      fetch('wwww.example.com')
        .then(r => r.json())
        .then(r => action.asyncDispatch({ type: "fetch-response", value: r }))
      return state;

    case "fetch-response":
      return Object.assign({}, state, { whatever: action.value });;
  }
}

aribeiro answer has worked for me - with minor changes

• I Removed the reference to C:\ProgramData\Oracle\Java\javapath; from the Path environment variable
• I made /path/to/jdkhome as the first entry in my PATH environment variable. I think this alone is all that is needed.

You have not defined the variable input_line.

Add this:

string input_line;

And add this include.

#include <string>

Here is the full example. I also removed the semi-colon after the while loop, and you should have getline inside the while to properly detect the end of the stream.

#include <iostream>
#include <string>

int main() {
    for (std::string line; std::getline(std::cin, line);) {
        std::cout << line << std::endl;
    }
    return 0;
}

Put the identity element before the authentication element

You can also configure CXFNonSpringJAXRSServlet (assuming JSONProvider is used):

<init-param>
  <param-name>jaxrs.providers</param-name>
  <param-value>
      org.apache.cxf.jaxrs.provider.JSONProvider
      (writeXsiType=false)
  </param-value> 
</init-param>

Actually I don't know you want to this.

try this

INSERT INTO my_table (my_column)
SELECT
    (random() * 10) + 1
;

Here are a couple functions I wrote to get a file in a json format which can be passed around easily:

    //takes an array of JavaScript File objects
    function getFiles(files) {
        return Promise.all(files.map(file => getFile(file)));
    }

    //take a single JavaScript File object
    function getFile(file) {
        var reader = new FileReader();
        return new Promise((resolve, reject) => {
            reader.onerror = () => { reader.abort(); reject(new Error("Error parsing file"));}
            reader.onload = function () {

                //This will result in an array that will be recognized by C#.NET WebApi as a byte[]
                let bytes = Array.from(new Uint8Array(this.result));

                //if you want the base64encoded file you would use the below line:
                let base64StringFile = btoa(bytes.map((item) => String.fromCharCode(item)).join(""));

                //Resolve the promise with your custom file structure
                resolve({ 
                    bytes: bytes,
                    base64StringFile: base64StringFile,
                    fileName: file.name, 
                    fileType: file.type
                });
            }
            reader.readAsArrayBuffer(file);
        });
    }

    //using the functions with your file:

    file = document.querySelector('#files > input[type="file"]').files[0]
    getFile(file).then((customJsonFile) => {
         //customJsonFile is your newly constructed file.
         console.log(customJsonFile);
    });

    //if you are in an environment where async/await is supported

    files = document.querySelector('#files > input[type="file"]').files
    let customJsonFiles = await getFiles(files);
    //customJsonFiles is an array of your custom files
    console.log(customJsonFiles);

Everything is correct above, but one of facts simple explanation LAZY----There are cases when you want to delay the creation of an instance of your object until its first usage. This technique is known as lazy initialization or lazy instantiation. The main purpose of lazy initialization is to boost performance and reduce your memory footprint. If instantiating an instance of your type carries a large computational cost and the program might end up not actually using it, you would want to delay or even avoid wasting CPU cycles.

You can either give class name to all label so that all can have same width :

 .class-name {  width:200px;}

Example

.labelname{  width:200px;}

or you can simple give rest of label

label {  width:200px;  display: inline-block;}

You can get Google Drive to automatically convert csv files to Google Sheets by appending

?convert=true

to the end of the api url you are calling.

EDIT: Here is the documentation on available parameters: https://developers.google.com/drive/v2/reference/files/insert

Also, while searching for the above link, I found this question has already been answered here:

Upload CSV to Google Drive Spreadsheet using Drive v2 API

You can do this:

df.rename(columns={ df.columns[1]: "whatever" })

Combination of Mritunjay and Bartu's answers are full answer to this question. I copying the full example.

<input class="form-control" type="email"  required="" placeholder="username"
 oninvalid="this.setCustomValidity('Please Enter valid email')"
 oninput="setCustomValidity('')"></input>

Here,

this.setCustomValidity('Please Enter valid email')" - Display the custom message on invalidated of the field

oninput="setCustomValidity('')" - Remove the invalidate message on validated filed.

Yes, image alt text can be styled using any style property you use for regular text, such as font-size, font-weight, line-height, color, background-color,etc. The line-height (of text) or vertical-align (if display:table-cell used) could also be used to vertically align alt text within an image element or image wrapping container, i.e. div.

To prevent accessibility issues regarding contrast, and inheriting the browser's default black font color when you've set a dark blue background-color, always set both the color of your font and its background-color at the same time.

This answers is to add an alternative for those VIM users like I that prefers to do everything within the editor.

TL;DR

Tpope came up with this great plugin for VIM called fugitive. Once installed you can run :Gstatus to check the files that have conflict and :Gdiff to open Git in a 3 ways merge.

Once in the 3-ways merge, fugitive will let you get the changes of any of the branches you are merging in the following fashion:

• :diffget //2, get changes from original (HEAD) branch:
• :diffget //3, get changes from merging branch:

Once you are finished merging the file, type :Gwrite in the merged buffer. Vimcasts released a great video explaining in detail this steps.

"By default, when an application calls DriverManager.getConnection(url, ...) and the database specified in the URL does not yet exist, a new (empty) database is created."—H2 Database.

Addendum: @Thomas Mueller shows how to Execute SQL on Connection, but I sometimes just create and populate in the code, as suggested below.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

/** @see http://stackoverflow.com/questions/5225700 */
public class H2MemTest {

    public static void main(String[] args) throws Exception {
        Connection conn = DriverManager.getConnection("jdbc:h2:mem:", "sa", "");
        Statement st = conn.createStatement();
        st.execute("create table customer(id integer, name varchar(10))");
        st.execute("insert into customer values (1, 'Thomas')");
        Statement stmt = conn.createStatement();
        ResultSet rset = stmt.executeQuery("select name from customer");
        while (rset.next()) {
            String name = rset.getString(1);
            System.out.println(name);
        }
    }
}

DataSource is vendor-specific, for MySql you could use MysqlDataSource which is provided in the MySql Java connector jar:

    MysqlDataSource dataSource = new MysqlDataSource();
    dataSource.setDatabaseName("xyz");
    dataSource.setUser("xyz");
    dataSource.setPassword("xyz");
    dataSource.setServerName("xyz.yourdomain.com");

Well, you should think about one more thing.

If you have a really big dataset, like 1,000,000 examples, split 80/10/10 may be unnecessary, because 10% = 100,000 examples may be just too much for just saying that model works fine.

Maybe 99/0.5/0.5 is enough because 5,000 examples can represent most of the variance in your data and you can easily tell that model works good based on these 5,000 examples in test and dev.

Don't use 80/20 just because you've heard it's ok. Think about the purpose of the test set.

Another simple way is to use the pivot function to format the data as you need first.

df.plot() does the rest

df = pd.DataFrame([
    ['red', 0, 0],
    ['red', 1, 1],
    ['red', 2, 2],
    ['red', 3, 3],
    ['red', 4, 4],
    ['red', 5, 5],
    ['red', 6, 6],
    ['red', 7, 7],
    ['red', 8, 8],
    ['red', 9, 9],
    ['blue', 0, 0],
    ['blue', 1, 1],
    ['blue', 2, 4],
    ['blue', 3, 9],
    ['blue', 4, 16],
    ['blue', 5, 25],
    ['blue', 6, 36],
    ['blue', 7, 49],
    ['blue', 8, 64],
    ['blue', 9, 81],
], columns=['color', 'x', 'y'])

df = df.pivot(index='x', columns='color', values='y')

df.plot()

pivot effectively turns the data into:

<video controls width=800 autoplay>
    <source src="file path here">
</video>

This will display the video (.mkv) using Google Chrome browser only.

Run sudo visudo command then set -%sudo ALL=(ALL:ALL) to %sudo ALL=(ALL:ALL) NOPASSWD: ALL it will work.

            (err)->
                return callback err if err
                callback null, subdirs

The primary purpose is to avoid chained indexing and eliminate the SettingWithCopyWarning.

Here chained indexing is something like dfc['A'][0] = 111

The document said chained indexing should be avoided in Returning a view versus a copy. Here is a slightly modified example from that document:

In [1]: import pandas as pd

In [2]: dfc = pd.DataFrame({'A':['aaa','bbb','ccc'],'B':[1,2,3]})

In [3]: dfc
Out[3]:
    A   B
0   aaa 1
1   bbb 2
2   ccc 3

In [4]: aColumn = dfc['A']

In [5]: aColumn[0] = 111
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [6]: dfc
Out[6]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

Here the aColumn is a view and not a copy from the original DataFrame, so modifying aColumn will cause the original dfc be modified too. Next, if we index the row first:

In [7]: zero_row = dfc.loc[0]

In [8]: zero_row['A'] = 222
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [9]: dfc
Out[9]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

This time zero_row is a copy, so the original dfc is not modified.

From these two examples above, we see it's ambiguous whether or not you want to change the original DataFrame. This is especially dangerous if you write something like the following:

In [10]: dfc.loc[0]['A'] = 333
SettingWithCopyWarning: 
A value is trying to be set on a copy of a slice from a DataFrame

In [11]: dfc
Out[11]:
    A   B
0   111 1
1   bbb 2
2   ccc 3

This time it didn't work at all. Here we wanted to change dfc, but we actually modified an intermediate value dfc.loc[0] that is a copy and is discarded immediately. It’s very hard to predict whether the intermediate value like dfc.loc[0] or dfc['A'] is a view or a copy, so it's not guaranteed whether or not original DataFrame will be updated. That's why chained indexing should be avoided, and pandas generates the SettingWithCopyWarning for this kind of chained indexing update.

Now is the use of .copy(). To eliminate the warning, make a copy to express your intention explicitly:

In [12]: zero_row_copy = dfc.loc[0].copy()

In [13]: zero_row_copy['A'] = 444 # This time no warning

Since you are modifying a copy, you know the original dfc will never change and you are not expecting it to change. Your expectation matches the behavior, then the SettingWithCopyWarning disappears.

Note, If you do want to modify the original DataFrame, the document suggests you use loc:

In [14]: dfc.loc[0,'A'] = 555

In [15]: dfc
Out[15]:
    A   B
0   555 1
1   bbb 2
2   ccc 3

When setting a Selected row of a DataGridView at load time, consider handling this in the DataBindingComplete event, because it can be overwritten by default.

I believe the following work in version 0.11 and above. To check the version:

$ ipython --version

It may be worth adding this information to your question.

Solution:

You need to find the file ipython_notebook_config.py. Depending on your installation process this should be in somewhere like

.config/ipython/profile_default/ipython_notebook_config.py

where .config is in your home directory.

Once you have located this file find the following lines

# Subset of matplotlib rcParams that should be different for the inline backend.
# c.InlineBackend.rc = {'font.size': 10, 'figure.figsize': (6.0, 4.0), 'figure.facecolor': 'white', 'savefig.dpi': 72, 'figure.subplot.bottom': 0.125, 'figure.edgecolor': 'white'}

Uncomment this line c.InlineBack... and define your default figsize in the second dictionary entry.

Note that this could be done in a python script (and hence interactively in IPython) using

pylab.rcParams['figure.figsize'] = (10.0, 8.0)

You say you want to delete any column with the title "Percent Margin of Error" so let's try to make this dynamic instead of naming columns directly.

Sub deleteCol()

On Error Resume Next

Dim wbCurrent As Workbook
Dim wsCurrent As Worksheet
Dim nLastCol, i As Integer

Set wbCurrent = ActiveWorkbook
Set wsCurrent = wbCurrent.ActiveSheet
'This next variable will get the column number of the very last column that has data in it, so we can use it in a loop later
nLastCol = wsCurrent.Cells.Find("*", LookIn:=xlValues, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column

'This loop will go through each column header and delete the column if the header contains "Percent Margin of Error"
For i = nLastCol To 1 Step -1
    If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) > 0 Then
        wsCurrent.Columns(i).Delete Shift:=xlShiftToLeft
    End If
Next i

End Sub

With this you won't need to worry about where you data is pasted/imported to, as long as the column headers are in the first row.

EDIT: And if your headers aren't in the first row, it would be a really simple change. In this part of the code: If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) change the "1" in Cells(1, i) to whatever row your headers are in.

EDIT 2: Changed the For section of the code to account for completely empty columns.

You can use the .hide() function bound to a click handler:

$('#Comanda').click(function() {
    $(this).hide();
});

Swift code example:

import UIKit
import AudioToolbox

class ViewController: UIViewController {  

override func viewDidLoad() {
    super.viewDidLoad()
}

@IBAction func notePressed(_ sender: UIButton) {

    // Load "mysoundname.wav"

    if let soundURL = Bundle.main.url(forResource: "note1", withExtension: "wav") {
        var mySound: SystemSoundID = 0
        AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
    // Play

        AudioServicesPlaySystemSound(mySound);
    }
}

Wanted to post this as a comment as a side note to the accepted answer, but that got a bit unclear. So purely as a side note:

If you have no need for the objects themselves and you want to have your project clear of further unused classes, you can parse with something like:

var list = JObject.Parse(json)["People"].Select(el => new { FirstName = (string)el["FirstName"], LastName = (string)el["LastName"] }).ToList();

var firstNames = list.Select(p => p.FirstName).ToList();
var lastNames = list.Select(p => p.LastName).ToList();

Even when using a strongly typed person class, you can still skip the root object by creating a list with JObject.Parse(json)["People"].ToObject<List<Person>>() Of course, if you do need to reuse the objects, it's better to create them from the start. Just wanted to point out the alternative ;)

DataTable.Clone() should do the trick.

DataTable newTable = originalTable.Clone();

sqldf provides a nice solution

a1 <- data.frame(a = 1:5, b=letters[1:5])
a2 <- data.frame(a = 1:3, b=letters[1:3])

require(sqldf)

a1NotIna2 <- sqldf('SELECT * FROM a1 EXCEPT SELECT * FROM a2')

And the rows which are in both data frames:

a1Ina2 <- sqldf('SELECT * FROM a1 INTERSECT SELECT * FROM a2')

The new version of dplyr has a function, anti_join, for exactly these kinds of comparisons

require(dplyr) 
anti_join(a1,a2)

And semi_join to filter rows in a1 that are also in a2

semi_join(a1,a2)

Actually you are right: it runs another instance of make. A possible solution would be:

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : clean clearscr all

clearscr:
    clear

By calling make fresh you get first the clean target, then the clearscreen which runs clear and finally all which does the job.

EDIT Aug 4

What happens in the case of parallel builds with make’s -j option? There's a way of fixing the order. From the make manual, section 4.2:

Occasionally, however, you have a situation where you want to impose a specific ordering on the rules to be invoked without forcing the target to be updated if one of those rules is executed. In that case, you want to define order-only prerequisites. Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only: targets : normal-prerequisites | order-only-prerequisites

The normal prerequisites section may of course be empty. Also, you may still declare multiple lines of prerequisites for the same target: they are appended appropriately. Note that if you declare the same file to be both a normal and an order-only prerequisite, the normal prerequisite takes precedence (since they are a strict superset of the behavior of an order-only prerequisite).

Hence the makefile becomes

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : | clean clearscr all

clearscr:
    clear

EDIT Dec 5

It is not a big deal to run more than one makefile instance since each command inside the task will be a sub-shell anyways. But you can have reusable methods using the call function.

log_success = (echo "\x1B[32m>> $1\x1B[39m")
log_error = (>&2 echo "\x1B[31m>> $1\x1B[39m" && exit 1)

install:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  command1  # this line will be a subshell
  command2  # this line will be another subshell
  @command3  # Use `@` to hide the command line
  $(call log_error, "It works, yey!")

uninstall:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  ....
  $(call log_error, "Nuked!")

as posted by @randymohan, with using statements instead

public static void WriteLog(string strLog)
{
    string logFilePath = @"C:\Logs\Log-" + System.DateTime.Today.ToString("MM-dd-yyyy") + "." + "txt";
    FileInfo logFileInfo = new FileInfo(logFilePath);
    DirectoryInfo logDirInfo = new DirectoryInfo(logFileInfo.DirectoryName);
    if (!logDirInfo.Exists) logDirInfo.Create();
    using (FileStream fileStream = new FileStream(logFilePath, FileMode.Append))
    {
        using (StreamWriter log = new StreamWriter(fileStream))
        {
            log.WriteLine(strLog);
        }
    }
}

As BalusC indicated, the actionListener by default swallows exceptions, but in JSF 2.0 there is a little more to this. Namely, it doesn't just swallows and logs, but actually publishes the exception.

This happens through a call like this:

context.getApplication().publishEvent(context, ExceptionQueuedEvent.class,                                                          
    new ExceptionQueuedEventContext(context, exception, source, phaseId)
);

The default listener for this event is the ExceptionHandler which for Mojarra is set to com.sun.faces.context.ExceptionHandlerImpl. This implementation will basically rethrow any exception, except when it concerns an AbortProcessingException, which is logged. ActionListeners wrap the exception that is thrown by the client code in such an AbortProcessingException which explains why these are always logged.

This ExceptionHandler can be replaced however in faces-config.xml with a custom implementation:

<exception-handlerfactory>
   com.foo.myExceptionHandler
</exception-handlerfactory>

Instead of listening globally, a single bean can also listen to these events. The following is a proof of concept of this:

@ManagedBean
@RequestScoped
public class MyBean {

    public void actionMethod(ActionEvent event) {

        FacesContext.getCurrentInstance().getApplication().subscribeToEvent(ExceptionQueuedEvent.class, new SystemEventListener() {

        @Override
        public void processEvent(SystemEvent event) throws AbortProcessingException {
            ExceptionQueuedEventContext content = (ExceptionQueuedEventContext)event.getSource();
            throw new RuntimeException(content.getException());
        }

        @Override
        public boolean isListenerForSource(Object source) {
            return true;
        }
        });

        throw new RuntimeException("test");
    }

}

(note, this is not how one should normally code listeners, this is only for demonstration purposes!)

Calling this from a Facelet like this:

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">
    <h:body>
        <h:form>
            <h:commandButton value="test" actionListener="#{myBean.actionMethod}"/>
        </h:form>
    </h:body>
</html>

Will result in an error page being displayed.

It should be document.getElementById("hidden").style.display = "block"; not document.getElementById["hidden"].style.display = "block";

EDIT due to author edit:

Why are you using a <div> here? Just add an ID to the table element and add a hidden style to it. E.g. <td id="hidden" style="display:none" class="depot_table_left">

This is my way to find the rootstart. Create at ROOT start a file with name mainpath.php

<?php 
## DEFINE ROOTPATH
$check_data_exist = ""; 

$i_surf = 0;

// looking for mainpath.php at the aktiv folder or higher folder

while (!file_exists($check_data_exist."mainpath.php")) {
  $check_data_exist .= "../"; 
  $i_surf++;
  // max 7 folder deep
  if ($i_surf == 7) { 
   return false;
  }
}

define("MAINPATH", ($check_data_exist ? $check_data_exist : "")); 
?>

For me is that the best and easiest way to find them. ^^

For those who are still unable to get it working, try the following in addition to the method provided by @CallMeBob.

PHP.ini

1. Go to C:\xampp\php , edit php.ini file with notepad.
2. Press CTRL+F on your keyboard, input sendmail_path on the search bar and click Find Next twice.
3. Right now, you should be at the [mail munction] section.

Remove the semicolon for this line: sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"
Add a semicolon for this line: sendmail_path="C:\xampp\mailtodisk\mailtodisk.exe"

SendMail.ini

• Go to C:\xampp\sendmail, edit sendmail.ini file with notepad
• Change the following:
  

• smtp_server=smtp.gmail.com
• smtp_port=465
• [email protected]
• auth_password=your-gmail-password
• [email protected]

Note:
** smtp_port must tally with your those written in your php code.
** Remember to change your-gmail-username and your-gmail-password to whichever account you are using.
**

Hope this helps! :)

For anyone who finds this page looking for unix timestamp w/ milliseconds, the documentation says

moment().valueOf()

or

+moment();

you can also get it through moment().format('x') (or .format('X') [capital X] for unix seconds with decimal milliseconds), but that will give you a string. Which moment.js won't actually parse back afterwards, unless you convert/cast it back to a number first.

Step 1 Included the cdn like

     <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

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

Step 2 Code Like

  $(document).ready(function(){
        $("#submit").click(function () {
              $('#myform').validate({ // initialize the plugin
                rules: {
                    id: {
                        required: true,
                        email: true
                    },
                    password: {
                        required: true,
                        minlength: 1
                    }
                },
                messages: {
                    id: {
                        required: "Enter Email Id"

                    },
                    password: {
                        required: "Enter Email Password"

                    }
                },
                submitHandler: function (form) { // for demo
                    alert('valid form submitted'); // for demo
                    return false; // for demo
                }
            });
       }):
  }); 

Another possibility is to use bit sets, for which there is at least one package or you can use the built-in big package. In this case, basically you need to define a way to convert your object to an index.

If you want be sure you need to check both

SomeProperty == null || SomeProperty == Guid.Empty

Because it can be null 'Nullable' and it can be an empty GUID something like this {00000000-0000-0000-0000-000000000000}

getSupportFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener()
    {
        @Override
        public void onBackStackChanged()
        {
            if (getSupportFragmentManager().getBackStackEntryCount() == 0)
            {
                //setToolbarTitle("Main Activity");
            }
            else
            {
                Log.e("fragment_replace11111", "replace");
            }
        }
    });


YourActivity.java
@Override
public void onBackPressed()
{
 Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.Fragment_content);
  if (fragment instanceof YourFragmentName)
    {
        fragmentReplace(new HomeFragment(),"Home Fragment");
        txt_toolbar_title.setText("Your Fragment");
    }
  else{
     super.onBackPressed();
   }
 }


public void fragmentReplace(Fragment fragment, String fragment_name)
{
    try
    {
        fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.Fragment_content, fragment, fragment_name);
        fragmentTransaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);
        fragmentTransaction.addToBackStack(fragment_name);
        fragmentTransaction.commitAllowingStateLoss();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

Use:

function random_color(format)
{
    var rint = Math.round(0xffffff * Math.random());
    switch(format)
    {
        case 'hex':
            return ('#0' + rint.toString(16)).replace(/^#0([0-9a-f]{6})$/i, '#$1');
            break;

        case 'rgb':
            return 'rgb(' + (rint >> 16) + ',' + (rint >> 8 & 255) + ',' + (rint & 255) + ')';
            break;

        default:
            return rint;
            break;
    }
}

Updated version:

function random_color( format ){
  var rint = Math.floor( 0x100000000 * Math.random());
  switch( format ){
    case 'hex':
      return '#' + ('00000'   + rint.toString(16)).slice(-6).toUpperCase();
    case 'hexa':
      return '#' + ('0000000' + rint.toString(16)).slice(-8).toUpperCase();
    case 'rgb':
      return 'rgb('  + (rint & 255) + ',' + (rint >> 8 & 255) + ',' + (rint >> 16 & 255) + ')';
    case 'rgba':
      return 'rgba(' + (rint & 255) + ',' + (rint >> 8 & 255) + ',' + (rint >> 16 & 255) + ',' + (rint >> 24 & 255)/255 + ')';
    default:
      return rint;
  }
}

$time_PHP = strtotime( $datetime_SQL );

Clearest and fastest way to do it.

You can also consider using a set, but constructing that set from your list may take more time than faster membership testing will save. The only way to be certain is to benchmark well. (this also depends on what operations you require)

I had the same problem. After a couple of hours of trouble shooting found that,

Instead of setting a limit on length I would propose the following, which has worked for me.

Inside:

config/database.php

replace this line for mysql:

'engine' => 'InnoDB ROW_FORMAT=DYNAMIC',

with:

'engine' => null,

Here's how you can do that.

Writing the persistent cookie.

//create a cookie
HttpCookie myCookie = new HttpCookie("myCookie");

//Add key-values in the cookie
myCookie.Values.Add("userid", objUser.id.ToString());

//set cookie expiry date-time. Made it to last for next 12 hours.
myCookie.Expires = DateTime.Now.AddHours(12);

//Most important, write the cookie to client.
Response.Cookies.Add(myCookie);

Reading the persistent cookie.

//Assuming user comes back after several hours. several < 12.
//Read the cookie from Request.
HttpCookie myCookie = Request.Cookies["myCookie"];
if (myCookie == null)
{
    //No cookie found or cookie expired.
    //Handle the situation here, Redirect the user or simply return;
}

//ok - cookie is found.
//Gracefully check if the cookie has the key-value as expected.
if (!string.IsNullOrEmpty(myCookie.Values["userid"]))
{
    string userId = myCookie.Values["userid"].ToString();
    //Yes userId is found. Mission accomplished.
}

Whenever you are creating activity, you must add setcontentview(your layout) after super call. Because setcontentview bind xml into your activity so that's the reason you are getting nullpointerexception.

 setContentView(R.layout.webview);  
 webView = (WebView) findViewById(R.id.webView1);
 wv.loadUrl("file:///android_asset/xyz.html");

But I get an error "! [rejected]" and something about "non fast forward"

That's because Git can't merge the changes from the branches into your current master. Let's say you've checked out branch master, and you want to merge in the remote branch other-branch. When you do this:

$ git pull origin other-branch

Git is basically doing this:

$ git fetch origin other-branch && git merge other-branch

That is, a pull is just a fetch followed by a merge. However, when pull-ing, Git will only merge other-branch if it can perform a fast-forward merge. A fast-forward merge is a merge in which the head of the branch you are trying to merge into is a direct descendent of the head of the branch you want to merge. For example, if you have this history tree, then merging other-branch would result in a fast-forward merge:

O-O-O-O-O-O
^         ^
master    other-branch

However, this would not be a fast-forward merge:

    v master
O-O-O
\
 \-O-O-O-O
         ^ other-branch

To solve your problem, first fetch the remote branch:

$ git fetch origin other-branch

Then merge it into your current branch (I'll assume that's master), and fix any merge conflicts:

$ git merge origin/other-branch
# Fix merge conflicts, if they occur
# Add merge conflict fixes
$ git commit    # And commit the merge!

You have to add the schema first e.g.

SELECT * FROM place.user_place;

If you don't want to add that in all queries then try this:

SET search_path TO place;

Now it will works:

SELECT * FROM user_place;

Try trimming the string to make sure there is no extra white space:

Cursor c = db.rawQuery("SELECT * FROM tbl1 WHERE TRIM(name) = '"+name.trim()+"'", null);

Also use c.moveToFirst() like @thinksteep mentioned.

This is a complete code for select statements.

SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT column1,column2,column3 FROM table ", null);
if (c.moveToFirst()){
    do {
        // Passing values 
        String column1 = c.getString(0);
        String column2 = c.getString(1);
        String column3 = c.getString(2); 
        // Do something Here with values
    } while(c.moveToNext());
}
c.close();
db.close();

Well, given your constraints, I think setting overflow: scroll; on the .page div is probably your only option. 280 px is pretty narrow, and given your font size, word wrapping alone isn't going to do it. Some words are just long and can't be wrapped. You can either reduce your font size drastically or go with overflow: scroll.

I have developed an Excel VBA Macro for cutting and pasting any selection from Excel into SQL Server, creating a new table. The macro is great for quick and dirty table creations up to a few thousand rows and multiple columns (It can theoretically manage up to 200 columns). The macro attempts to automatically detect header names and assign the most appropriate datatype to each column (it handles varchar columns upto 1000 chars).

Recommended Setup procedure:

1. Make sure Excel is enabled to run macros. (File->Options->Trust Center->Trust Center Settings->Macro Settings->Enable all macros..)
2. Copy the VBA code below to the module associated with your personal workbook (So that the Macro will be available for all worksheets)
3. Assign an appropriate keystroke to the macro ( I have assigned Ctrl Shift X)
4. Save your personal workbook

Use of Macro

1. Select the cells in Excel (including column headers if they exist) to be transferred to SQL
2. Press the assigned keyword combination that you have assigned to run the macro
3. Follow the prompts. (Default table name is ##Table)
4. Paste the clipboard contents into a SSMS window and run the generated SQL code. BriFri 238

In bash scripts, I found that escaping double quotes around the value was necessary for values that could be null or contained characters that require escaping (like hyphens).

In this example, columnA's value could be null or contain hyphens.:

sqlite3 $db_name "insert into foo values (\"$columnA\", $columnB)";

In android I would use this code:

Uri myUI = Uri.parse ("http://example.com/query").buildUpon().appendQueryParameter("q","random word A3500 bank 24").build();

Where Uri is a android.net.Uri

Dude, Just python test.py in your terminal.

f = open('/home/hduser/Desktop/data.csv' , 'r')

x = f.read().split()
f.close()

y = ' '.join(x)
f = open('/home/hduser/Desktop/data.csv','w')
f.write(y)
f.close()

.Net4.5 does not have a 2GB limitation for objects any more. Add this lines to App.config

<runtime>
    <gcAllowVeryLargeObjects enabled="true" />    
</runtime>

and it will be possible to create very large objects without getting OutOfMemoryException

Please note it will work only on x64 OS's!

If you start 64bit Android Studio, you have to add JAVA_HOME as

    "C:\Program Files\Java\jdk..."

If 32bit

    "C:\Program Files(x86)\Java\jdk..."

and dont put "\bin" end of the path.

If using a Mac

1. highlight column
2. copy
3. open terminal.app
4. type pbpaste|sort -u|wc -l

Linux users replace pbpaste with xclip xsel or similar

Windows users, it's possible but would take some scripting... start with http://brianreiter.org/2010/09/03/copy-and-paste-with-clipboard-from-powershell/

I'm not sure about Tomcat 7, but with Tomcat 6... once you start Tomcat: By going into the bin directory and starting startup.bat (win) or startup.sh (Unix/osx) it will spin up a local instance of the server running usually on port 8080 by default. Then by going to http://localhost:8080/ and seeing that it is running, there is a link to the manager. If that page is not there, you can try loading the manager by going directly to manager/html, and that will load the Host Manager gui.

http://localhost:8080/manager/html

Make sure Tomcat is running first and that 8080 is the right port. These are just the defaults that tomcat usually runs with.

To login you need to edit the conf/tomcat-users.xml, and create a Manager GUI role

<role rolename="manager-gui"/>

and add that to a user

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

Then when you go to Manager GUI app at http://localhost:8080/manager/html it will prompt you for a username/password, which you added to that config file.

As Kirill suggested, either use the replace method or iterate along the string replacing each char independently.

Alternatively you can use the find method or find_first_of depending on what you need to do. None of these solutions will do the job in one go, but with a few extra lines of code you ought to make them work for you. :-)

It is bounded on the lower end by 2^(n/2) and on the upper end by 2^n (as noted in other comments). And an interesting fact of that recursive implementation is that it has a tight asymptotic bound of Fib(n) itself. These facts can be summarized:

T(n) = O(2^(n/2))  (lower bound)
T(n) = O(2^n)   (upper bound)
T(n) = T(Fib(n)) (tight bound)

The tight bound can be reduced further using its closed form if you like.

function msToHMS( ms ) {
  // 1- Convert to seconds:
  var seconds = ms / 1000;

  // 2- Extract hours:
  var hours = parseInt( seconds / 3600 ); // 3,600 seconds in 1 hour
  seconds = seconds % 3600; // seconds remaining after extracting hours

  // 3- Extract minutes:
  var minutes = parseInt( seconds / 60 ); // 60 seconds in 1 minute

  // 4- Keep only seconds not extracted to minutes:
  seconds = seconds % 60;

  //alert( hours+":"+minutes+":"+seconds);
  hours = (hours < 10) ? "0" + hours : hours;
  minutes = (minutes < 10) ? "0" + minutes : minutes;
  seconds = (seconds < 10) ? "0" + seconds : seconds;
  var hms = hours+":"+minutes+":"+seconds;
  return hms;

Neither Glide nor Picasso is perfect. The way Glide loads an image to memory and do the caching is better than Picasso which let an image loaded far faster. In addition, it also helps preventing an app from popular OutOfMemoryError. GIF Animation loading is a killing feature provided by Glide. Anyway Picasso decodes an image with better quality than Glide.

Which one do I prefer? Although I use Picasso for such a very long time, I must admit that I now prefer Glide. But I would recommend you to change Bitmap Format to ARGB_8888 and let Glide cache both full-size image and resized one first. The rest would do your job great!

• Method count of Picasso and Glide are at 840 and 2678 respectively.
• Picasso (v2.5.1)'s size is around 118KB while Glide (v3.5.2)'s is around 430KB.
• Glide creates cached images per size while Picasso saves the full image and process it, so on load it shows faster with Glide but uses more memory.
• Glide use less memory by default with RGB_565.

+1 For Picasso Palette Helper.

There is a post that talk a lot about Picasso vs Glide post

Use git fetch to fetch all latest created branches.

var list = [

    { date: '14/1/2011', reading: 6, id: 45652 }
];

and then access it:

alert(list[1].date);

To fix the blank PDF issue in post request to get stream data like PDF, we need to add response type as 'arraybuffer' or 'blob' in request

$.ajax({
  url: '<URL>',
  type: "POST",
  dataType: 'arraybuffer',
  success: function(data) {
    let blob = new Blob([data], {type: 'arraybuffer'});
    let link = document.createElement('a');
    let objectURL = window.URL.createObjectURL(blob);
    link.href = objectURL;
    link.target = '_self';
    link.download = "fileName.pdf";
    (document.body || document.documentElement).appendChild(link);
    link.click();
    setTimeout(()=>{
        window.URL.revokeObjectURL(objectURL);
        link.remove();
    }, 100);
  }
});

Based on the Roman's most upvoted comment above, here is my implementation, Including "download as" and "retries" mechanism:

    if not file_path:
        file_path = os.path.realpath(os.path.basename(url))
    logger.info(f'Downloading {url} content to {file_path}')
    url_sections = urlparse(url)
    if not url_sections.scheme:
        logger.debug('The given url is missing a scheme. Adding http scheme')
        url = f'http://{url}'
        logger.debug(f'New url: {url}')
    for attempt in range(1, attempts+1):
        try:
            if attempt > 1:
                time.sleep(10)  # 10 seconds wait time between downloads
            with requests.get(url, stream=True) as response:
                response.raise_for_status()
                with open(file_path, 'wb') as out_file:
                    for chunk in response.iter_content(chunk_size=1024*1024):  # 1MB chunks
                        out_file.write(chunk)
                logger.info('Download finished successfully')
                return file_path
        except Exception as ex:
            logger.error(f'Attempt #{attempt} failed with error: {ex}')
    return ''

Suppose access a proxy server A(eg. nginx), and the server A forwards the request to another server B(eg. tomcat).

If this process continues for a long time (more than the proxy server read timeout setting), A still did not get a completed response of B. It happens.

for nginx, You can configure the proxy_read_timeout(in location) property to solve his.But this is usually not a good idea, if you set the value too high. This may hide the real error.You'd better improve the design to really solve this problem.

Prefix is the prefix for url routing. If it's equals to '/' it means it will have no prefix. Then you defined a route with pattern "it should start with /hello".

To create a route for '/' you need to add these lines in your src/Shop/MyShopBundle/Resources/config/routing.yml :

ShopMyShopBundle_homepage:
    pattern:  /
    defaults: { _controller: ShopMyShopBundle:Main:index }

We can use splatting for this:

& $command @args

where @args (automatic variable $args) is splatted into array of parameters.

df.groupby('Company Name').agg(MySum=('Amount', 'sum'), MyCount=('Amount', 'count'))

Update:

As of PHP 7.1, this is available.

The syntax is:

try
{
    // Some code...
}
catch(AError | BError $e)
{
    // Handle exceptions
}
catch(Exception $e)
{
    // Handle the general case
}

Docs: https://www.php.net/manual/en/language.exceptions.php#example-294

RFC: https://wiki.php.net/rfc/multiple-catch

Commit: https://github.com/php/php-src/commit/0aed2cc2a440e7be17552cc669d71fdd24d1204a

For PHP before 7.1:

Despite what these other answers say, you can catch AError and BError in the same block (it is somewhat easier if you are the one defining the exceptions). Even given that there are exceptions you want to "fall through", you should still be able to define a hierarchy to match your needs.

abstract class MyExceptions extends Exception {}

abstract class LetterError extends MyExceptions {}

class AError extends LetterError {}

class BError extends LetterError {}

Then:

catch(LetterError $e){
    //voodoo
}

As you can see here and here, even the SPL default exceptions have a hierarchy you can leverage. Additionally, as stated in the PHP Manual:

When an exception is thrown, code following the statement will not be executed, and PHP will attempt to find the first matching catch block.

This means you could also have

class CError extends LetterError {}

which you need to handle differently than AError or BError, so your catch statement would look like this:

catch(CError $e){
    //voodoo
}
catch(LetterError $e){
    //voodoo
}

If you had the case where there were twenty or more exceptions that legitimately belonged under the same superclass, and you needed to handle five (or whatever large-ish group) of them one way and the rest the other, you can STILL do this.

interface Group1 {}

class AError extends LetterError implements Group1 {}

class BError extends LetterError implements Group1 {}

And then:

catch (Group1 $e) {}

Using OOP when it comes to exceptions is very powerful. Using things like get_class or instanceof are hacks, and should be avoided if possible.

Another solution I would like to add is putting the exception handling functionality in its own method.

You could have

function handleExceptionMethod1(Exception $e)
{
    //voodoo
}

function handleExceptionMethod2(Exception $e)
{
    //voodoo
}

Assuming there is absolutely no way you can control exception class hierarchies or interfaces (and there almost always will be a way), you can do the following:

try
{
    stuff()
}
catch(ExceptionA $e)
{
    $this->handleExceptionMethod1($e);
}
catch(ExceptionB $e)
{
    $this->handleExceptionMethod1($e);
}
catch(ExceptionC $e)
{
    $this->handleExceptionMethod1($e);
}
catch(Exception $e)
{
    $this->handleExceptionMethod2($e);
}

In this way, you are still have a only single code location you have to modify if your exception handling mechanism needs to change, and you are working within the general constructs of OOP.

You must specify which type the response is

  this.productService.getProducts().subscribe(res => {
          this.productsArray = res;
        });

Try this

  this.productService.getProducts().subscribe((res: Product[]) => {
          this.productsArray = res;
        });

Inspired by samneric's answer using DataRowComparer.Default but needing something that would only compare a subset of columns within a DataTable, I made a DataTableComparer object where you can specify which columns to use in the comparison. Especially great if they have different columns/schemas.

DataRowComparer.Default works because it implements IEqualityComparer. Then I created an object where you can define which columns of the DataRow will be compared.

public class DataTableComparer : IEqualityComparer<DataRow>
{
    private IEnumerable<String> g_TestColumns;
    public void SetCompareColumns(IEnumerable<String> p_Columns)
    {
        g_TestColumns = p_Columns; 
    }

    public bool Equals(DataRow x, DataRow y)
    {

        foreach (String sCol in g_TestColumns)
            if (!x[sCol].Equals(y[sCol])) return false;

        return true;
    }

    public int GetHashCode(DataRow obj)
    {
        StringBuilder hashBuff = new StringBuilder();

        foreach (String sCol in g_TestColumns)
            hashBuff.AppendLine(obj[sCol].ToString());               

        return hashBuff.ToString().GetHashCode();

    }
}

You can use this by:

DataTableComparer comp = new DataTableComparer();
comp.SetCompareColumns(new String[] { "Name", "DoB" });

DataTable celebrities = SomeDataTableSource();
DataTable politicians = SomeDataTableSource2();

List<DataRow> celebrityPoliticians = celebrities.AsEnumerable().Intersect(politicians.AsEnumerable(), comp).ToList();

Write one table per join, like this:

select tab1.a,tab2.b,tab3.c,tab4.d 
from 
  table1 tab1
  inner join table2 tab2 on tab2.fg = tab1.fg
  left join table3 tab3 on tab3.xxx = tab1.xxx and tab3.desc = "XYZ"
  left join table4 tab4 on tab4.xya = tab3.xya and tab4.ss = tab3.ss
  left join table5 tab5 on tab5.dd = tab3.dd and tab5.kk = tab4.kk

Note that while my query contains actual left join, your query apparently doesn't. Since the conditions are in the where, your query should behave like inner joins. (Although I admit I don't know Informix, so maybe I'm wrong there).

The specfific Informix extension used in the question works a bit differently with regards to left joins. Apart from the exact syntax of the join itself, this is mainly in the fact that in Informix, you can specify a list of outer joined tables. These will be left outer joined, and the join conditions can be put in the where clause. Note that this is a specific extension to SQL. Informix also supports 'normal' left joins, but you can't combine the two in one query, it seems.

In Oracle this extension doesn't exist, and you can't put outer join conditions in the where clause, since the conditions will be executed regardless.

So look what happens when you move conditions to the where clause:

select tab1.a,tab2.b,tab3.c,tab4.d 
from 
  table1 tab1
  inner join table2 tab2 on tab2.fg = tab1.fg
  left join table3 tab3 on tab3.xxx = tab1.xxx
  left join table4 tab4 on tab4.xya = tab3.xya
  left join table5 tab5 on tab5.dd = tab3.dd and tab5.kk = tab4.kk
where
  tab3.desc = "XYZ" and
  tab4.ss = tab3.ss

Now, only rows will be returned for which those two conditions are true. They cannot be true when no row is found, so if there is no matching row in table3 and/or table4, or if ss is null in either of the two, one of these conditions is going to return false, and no row is returned. This effectively changed your outer join to an inner join, and as such changes the behavior significantly.

PS: left join and left outer join are the same. It means that you optionally join the second table to the first (the left one). Rows are returned if there is only data in the 'left' part of the join. In Oracle you can also right [outer] join to make not the left, but the right table the leading table. And there is and even full [outer] join to return a row if there is data in either table.

Keep in mind that international users may be using a decimal separator other than . in which case values can get mixed up or just become nil when using intValue on a string.

For example, in the UK 1.23 is written 1,23, so the number 1.777 would be input by user as 1,777, which, as .intValue, will be 1777 not 1 (truncated).

I've made a macro that will convert input text to an NSNumber based on a locale argument which can be nil (if nil it uses device current locale).

#define stringToNumber(__string, __nullable_locale) (\
(^NSNumber *(void){\
NSLocale *__locale = __nullable_locale;\
if (!__locale) {\
__locale = [NSLocale currentLocale];\
}\
NSString *__string_copy = [__string stringByReplacingOccurrencesOfString:__locale.groupingSeparator withString:@""];\
__string_copy = [__string_copy stringByReplacingOccurrencesOfString:__locale.decimalSeparator withString:@"."];\
return @([__string_copy doubleValue]);\
})()\
)

I doubt you'll get a better answer than, "Guido didn't feel the need for multi-line comments".

Guido has tweeted about this:

Python tip: You can use multi-line strings as multi-line comments. Unless used as docstrings, they generate no code! :-)

You can also use as Vector instead, as vectors are thread safe and arraylist are not. Though vectors are old but they can solve your purpose easily.

But you can make your Arraylist synchronized like code given this:

Collections.synchronizedList(new ArrayList(numberOfRaceCars())); 

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

So, if you are using flask_restful Package for API's returning 201 would becomes like

def bla(*args, **kwargs):
    ...
    return data, 201

where data should be any hashable/ JsonSerialiable value, like dict, string.

Use Math.ceil() and cast the result to int:

• This is still faster than to avoid doubles by using abs().
• The result is correct when working with negatives, because -0.999 will be rounded UP to 0

Example:

(int) Math.ceil((double)divident / divisor);

When you are using Postman for multipart request then don't specify a custom Content-Type in Header. So your Header tab in Postman should be empty. Postman will determine form-data boundary. In Body tab of Postman you should select form-data and select file type. You can find related discussion at https://github.com/postmanlabs/postman-app-support/issues/576

This will let you read, write and create the file if it don't exist:

f = open('filename.txt','a+')
f = open('filename.txt','r+')

Often used commands:

f.readline() #Read next line
f.seek(0) #Jump to beginning
f.read(0) #Read all file
f.write('test text') #Write 'test text' to file
f.close() #Close file

It's possible. But it's viewable anyway.

You can make this tool for yourself:

const btn = document.querySelector('.btn');
btn.onclick = textRead;
const copy = document.querySelector('.copy');
copy.onclick = Copy;
const file = document.querySelector('.file');
file.type = 'file';
const pre = document.querySelector('.pre');

var pretxt = pre;

if (pre.innerHTML == "") {
    copy.hidden = true;
}

function textRead() {
    let file = document.querySelector('.file').files[0];
    let read = new FileReader();
    read.addEventListener('load', function(e) {
        let data = e.target.result;
        pre.textContent = data;
    });
    read.readAsDataURL(file);
    copy.hidden = false;
}

function Copy() {
    var text = pre;
    var selection = window.getSelection();
    var range = document.createRange();
    range.selectNodeContents(text);
    selection.addRange(range);
    document.execCommand('copy');
    selection.removeAllRanges();
}

<input class="file" />
<br>
<button class="btn">Read File</button>
<pre class="pre"></pre>
<button class="copy">Copy</button>

How to use this tool?

1. Create a JavaScript file.
2. Go in the tool and choose your JavaScript file.
3. Copy result.
4. Paste the result in Notepad.
5. Remove data:text/javascript;base64,.
6. Paste eval(atob('Notepad Text')) to your code and change Notepad Text to your Notepad text result.

How to view this hidden code?

1. Copy the hidden code and paste it in Notepad.
2. Copy a string that after eval and atob.
3. Paste data:text/javascript;base64,String and change String to your copied string.

You don't need align="center" and float:left. Remove both of these. margin: 0 auto is sufficient.

This is by far (after hours of googling and trying scripts) the simplest to set up and nicest uploader I've found

https://github.com/FineUploader/fine-uploader

It doesn't require APC or any other external PHP libraries, I can get file progress feedback on a shared host, and it claims to support html5 drag and drop (personally untested) and multiple file uploads.

<div id='parent' style='width: 100%;text-align:center;'>
 <div id='child' style='width:50px; height:100px;margin:0px auto;'>Text</div>
</div>

Perl was likely the first language to use it. Groovy is another language that supports it. Basically instead of returning 1 (true) or 0 (false) depending on whether the arguments are equal or unequal, the spaceship operator will return 1, 0, or -1 depending on the value of the left argument relative to the right argument.

a <=> b :=
  if a < b then return -1
  if a = b then return  0
  if a > b then return  1
  if a and b are not comparable then return nil

It's useful for sorting an array.

As Douglas Leeder said you need a separate process for timeout to signal to. Workaround by exporting function to subshells and running subshell manually.

export -f echoFooBar
timeout 10s bash -c echoFooBar

You have two possible ways of doing it:

• do not redirect user upon error and display {{ form_errors(form) }} within template file
• access error array as $form->getErrors()

A semaphore is a signaling mechanism used to coordinate between threads. Example: One thread is downloading files from the internet and another thread is analyzing the files. This is a classic producer/consumer scenario. The producer calls signal() on the semaphore when a file is downloaded. The consumer calls wait() on the same semaphore in order to be blocked until the signal indicates a file is ready. If the semaphore is already signaled when the consumer calls wait, the call does not block. Multiple threads can wait on a semaphore, but each signal will only unblock a single thread.

A counting semaphore keeps track of the number of signals. E.g. if the producer signals three times in a row, wait() can be called three times without blocking. A binary semaphore does not count but just have the "waiting" and "signalled" states.

A mutex (mutual exclusion lock) is a lock which is owned by a single thread. Only the thread which have acquired the lock can realease it again. Other threads which try to acquire the lock will be blocked until the current owner thread releases it. A mutex lock does not in itself lock anything - it is really just a flag. But code can check for ownership of a mutex lock to ensure that only one thread at a time can access some object or resource.

A monitor is a higher-level construct which uses an underlying mutex lock to ensure thread-safe access to some object. Unfortunately the word "monitor" is used in a few different meanings depending on context and platform and context, but in Java for example, a monitor is a mutex lock which is implicitly associated with an object, and which can be invoked with the synchronized keyword. The synchronized keyword can be applied to a class, method or block and ensures only one thread can execute the code at a time.

I will just add a blank ("") to the end of the variable and do the comparison. Something like below should work even when that variable is null. You can also trim the variable just in case of spaces.

If provider & "" <> "" Then 
    url = url & "&provider=" & provider 
End if

vim -c 'execute "silent !echo " . &fileencoding | q' {filename}

aliased somewhere in my bash configuration as

alias vic="vim -c 'execute \"silent \!echo \" . &fileencoding | q'"

so I just type

vic {filename}

On my vanilla OSX Yosemite, it yields more precise results than "file -I":

$ file -I pdfs/udocument0.pdf
pdfs/udocument0.pdf: application/pdf; charset=binary
$ vic pdfs/udocument0.pdf
latin1
$
$ file -I pdfs/t0.pdf
pdfs/t0.pdf: application/pdf; charset=us-ascii
$ vic pdfs/t0.pdf
utf-8

I found this answer quite simple and did the trick for what I needed: https://stackoverflow.com/a/12956348/652519

A summary from the link, use this query:

EXEC sp_fkeys 'TableName'

Quick and simple. I was able to locate all the foreign key tables, respective columns and foreign key names of 15 tables pretty quickly.

As @mdisibio noted below, here's a link to the documentation that details the different parameters that can be used: https://docs.microsoft.com/en-us/sql/relational-databases/system-stored-procedures/sp-fkeys-transact-sql

I used the code below to get mine to work in Chrome. You can adjust the nesting:

a:-webkit-any-link { color: black; }

The simplest solution would be open terminal

$ java -version

it shows the following

java version "1.6.0_65"

2. Stefan's solution also works for me. Here's the exact input:

$ cd /System/Library/Frameworks/JavaVM.framework/Versions

$ ls -l

Below is the last line of output:

lrwxr-xr-x   1 root  wheel   59 Feb 12 14:57 CurrentJDK -> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents

1.6.0.jdk would be the answer

 public static long bytesToLong(byte[] bytes) {
        if (bytes.length > 8) {
            throw new IllegalMethodParameterException("byte should not be more than 8 bytes");

        }
        long r = 0;
        for (int i = 0; i < bytes.length; i++) {
            r = r << 8;
            r += bytes[i];
        }

        return r;
    }



public static byte[] longToBytes(long l) {
        ArrayList<Byte> bytes = new ArrayList<Byte>();
        while (l != 0) {
            bytes.add((byte) (l % (0xff + 1)));
            l = l >> 8;
        }
        byte[] bytesp = new byte[bytes.size()];
        for (int i = bytes.size() - 1, j = 0; i >= 0; i--, j++) {
            bytesp[j] = bytes.get(i);
        }
        return bytesp;
    }

var number = 10000;
var result = .358 * number;

You can use standard STL function distance as mentioned before

index = std::distance(s.begin(), it);

Also, you can access string and some other containers with the c-like interface:

for (i=0;i<string1.length();i++) string1[i];

Simply use the global keyword.

e.g.:

class myClass() {
    private function foo() {
        global $MyNumber;
        ...

$MyNumber will then become accessible (and indeed modifyable) within that method.

However, the use of globals is often frowned upon (they can give off a bad code smell), so you might want to consider using a singleton class to store anything of this nature. (Then again, without knowing more about what you're trying to achieve this might be a very bad idea - a define could well be more useful.)

#header {
margin: 0;
padding: 0;
width: 100%;
background: xxxx;
}

#header #content {

width: 800px; /* or whatever */
}

<div id="header">
<div id="content">

</div>
</div>

Using round:

>>> numvar = 135.12345678910
>>> str(round(numvar, 9))
'135.123456789'

Why do you need a cursor at all? Your entire segment of code can be replaced by this, which will run a lot faster on large numbers of rows.

public static final long SECOND_IN_MILLIS = 1000;

public static final long DAY_IN_MILLIS = HOUR_IN_MILLIS * 24;
public static final long WEEK_IN_MILLIS = DAY_IN_MILLIS * 7;

You could cast int but I would recommend using long.

You should be able to use

You can get a non-js-based redirection from an ajax call by putting in one of those meta refresh tags. This here seems to be working: return Content("<meta http-equiv=\"refresh\" content=\"0;URL='" + @Url.Action("Index", "Home") + "'\" />");

Note: I discovered that meta refreshes are auto-disabled by Firefox, rendering this not very useful.

type NumberArray = Array<{id: number, text: string}>;

const arr: NumberArray = [
    {id: 0, text: 'Number 0'},
    {id: 1, text: 'Number 1'},
    {id: 2, text: 'Number 2'},
    {id: 3, text: 'Number 3 '},
    {id: 4, text: 'Number 4 '},
    {id: 5, text: 'Number 5 '},
];

A much more secure way to check if property exists on the object is to use empty object or object prototype to call hasOwnProperty()

var foo = {
  hasOwnProperty: function() {
    return false;
  },
  bar: 'Here be dragons'
};

foo.hasOwnProperty('bar'); // always returns false

// Use another Object's hasOwnProperty and call it with 'this' set to foo
({}).hasOwnProperty.call(foo, 'bar'); // true

// It's also possible to use the hasOwnProperty property from the Object
// prototype for this purpose
Object.prototype.hasOwnProperty.call(foo, 'bar'); // true

Reference from MDN Web Docs - Object.prototype.hasOwnProperty()

from item in db.vw_Dropship_OrderItems
    where (listStatus != null ? listStatus.Contains(item.StatusCode) : true) &&
    (listMerchants != null ? listMerchants.Contains(item.MerchantId) : true)
    select item;

Might give strange behavior if both listMerchants and listStatus are both null.

In ES6, just one line.

const arr = arr.filter(item => item.key !== "some value");

:)

if array is look like this [null] or [null, null] or [null, null, null, ...]

you can use implode:

implode is use for convert array to string.

if(implode(null,$arr)==null){
     //$arr is empty
}else{
     //$arr has some value rather than null
}

Avoid writing functions for such small tasks, unless you apply them often, as it will clutter up your code.

for individual values:

min(clamp_max, max(clamp_min, value))

for lists of values:

map(lambda x: min(clamp_max, max(clamp_min, x)), values)

The syntax to statically initialize an array uses curly braces, like this:

int array[10] = { 0 };

This will zero-initialize the array.

For multi-dimensional arrays, you need nested curly braces, like this:

int cipher[Array_size][Array_size]= { { 0 } };

Note that Array_size must be a compile-time constant for this to work. If Array_size is not known at compile-time, you must use dynamic initialization. (Preferably, an std::vector).

Not sure if it's what you mean, but you can do this:

plot(1:10, xaxt = "n", xlab='Some Letters')
axis(1, at=1:10, labels=letters[1:10])

which then gives you the graph:

php curl lib is just a wrapper of cUrl, so, first of all, you should install cUrl. Download the cUrl source to your linux server. Then, use the follow commands to install:

tar zxvf cUrl_src_taz
cd cUrl_src_taz
./configure --prefix=/curl/install/home
make
make test    (optional)
make install
ln -s  /curl/install/home/bin/curl-config /usr/bin/curl-config

Then, copy the head files in the "/curl/install/home/include/" to "/usr/local/include". After all above steps done, the php curl extension configuration could find the original curl, and you can use the standard php extension method to install php curl.
Hope it helps you, :)

Same as @Sanchit Gupta.

in this part

if (results[0]) {
 var add= results[0].formatted_address ;
 var  value=add.split(",");
 count=value.length;
 country=value[count-1];
 state=value[count-2];
 city=value[count-3];
 x.innerHTML = "city name is: " + city;
}

just console the results array

if (results[0]) {
 console.log(results[0]);
 // choose from console whatever you need.
 var city = results[0].address_components[3].short_name;
 x.innerHTML = "city name is: " + city;
}

curl_getinfo() must be added before closing the curl handler

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://example.com/bar");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "someusername:secretpassword");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info['request_header']);
curl_close($ch);

You should provide output file name after -o option. In your case runexp.o is treated as output file name, not input object file and thus your main function is undefined.

You could modify the project configuration temporarily to save only the last 1 build, reload the configuration (which should trash the old builds), then change the configuration setting again to your desired value.

you can use use numpy.random module, you can get array of random number in shape of your choice you want

>>> import numpy as np
>>> np.random.random(1)[0]
0.17425892129128229
>>> np.random.random((3,2))
array([[ 0.7978787 ,  0.9784473 ],
       [ 0.49214277,  0.06749958],
       [ 0.12944254,  0.80929816]])
>>> np.random.random((3,1))
array([[ 0.86725993],
       [ 0.36869585],

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:

var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da

For Node.js v5.11.1 and below

Construct a new Buffer and pass 'base64' as the second argument:

var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da

If you want to be clean, you can check whether from exists :

if (typeof Buffer.from === "function") {
    // Node 5.10+
    buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
    // older Node versions, now deprecated
    buf = new Buffer(b64string, 'base64'); // Ta-da
}

public void keyReleased(KeyEvent e)
{
    int key=e.getKeyCode();
    if(e.getSource()==textField)
    {
        if(key==KeyEvent.VK_ENTER)
        { 
            Toolkit.getDefaultToolkit().beep();
            textField_1.requestFocusInWindow();                     
        }
    }

To write logic for 'Enter press' in JTextField, it is better to keep logic inside the keyReleased() block instead of keyTyped() & keyPressed().

Add this code in your ViewController.m file :

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self.view endEditing:YES];
}

No, you can't do this in Java. Aside from anything else, d would then presumably be an instance of A (given the normal idea of "extends"), but users who only knew about A wouldn't know about it - which defeats the point of an enum being a well-known set of values.

If you could tell us more about how you want to use this, we could potentially suggest alternative solutions.

For those who came here looking for a way to download a blob url video / audio, this answer worked for me. In short, you would need to find an *.m3u8 file on the desired web page through Chrome -> Network tab and paste it into a VLC player.

Another guide shows you how to save a stream with the VLC Player.

raw_input returns a string (a sequence of characters). In Python, multiplying a string and a float makes no defined meaning (while multiplying a string and an integer has a meaning: "AB" * 3 is "ABABAB"; how much is "L" * 3.14 ? Please do not reply "LLL|"). You need to parse the string to a numerical value.

You might want to try:

salesAmount = float(raw_input("Insert sale amount here\n"))

This works for me

1. Open the folder which contains the project file project.xcworkspace from the terminal.

2. Write this command: git rm --cached *xcuserstate

This will remove the file.

When passing by value:

void func(Object o);

and then calling

func(a);

you will construct an Object on the stack, and within the implementation of func it will be referenced by o. This might still be a shallow copy (the internals of a and o might point to the same data), so a might be changed. However if o is a deep copy of a, then a will not change.

When passing by reference:

void func2(Object& o);

and then calling

func2(a);

you will only be giving a new way to reference a. "a" and "o" are two names for the same object. Changing o inside func2 will make those changes visible to the caller, who knows the object by the name "a".

I understand the ZooKeeper in general but had problems with the terms "quorum" and "split brain" so maybe I can share my findings with you (I consider myself also a layman).

Let's say we have a ZooKeeper cluster of 5 servers. One of the servers will become the leader and the others will become followers.

• These 5 servers form a quorum. Quorum simply means "these servers can vote upon who should be the leader".

• So the voting is based on majority. Majority simply means "more than half" so more than half of the number of servers must agree for a specific server to become the leader.

• So there is this bad thing that may happen called "split brain". A split brain is simply this, as far as I understand: The cluster of 5 servers splits into two parts, or let's call it "server teams", with maybe one part of 2 and the other of 3 servers. This is really a bad situation as if both "server teams" must execute a specific order how would you decide wich team should be preferred? They might have received different information from the clients. So it is really important to know what "server team" is still relevant and which one can/should be ignored.

• Majority is also the reason you should use an odd number of servers. If you have 4 servers and a split brain where 2 servers seperate then both "server teams" could say "hey, we want to decide who is the leader!" but how should you decide which 2 servers you should choose? With 5 servers it's simple: The server team with 3 servers has the majority and is allowed to select the new leader.

• Even if you just have 3 servers and one of them fails the other 2 still form the majority and can agree that one of them will become the new leader.

I realize once you think about it some time and understand the terms it's not so complicated anymore. I hope this also helps anyone in understanding these terms.

You can use input.value = JSON.stringify(obj) to transform the object to a string.
And when you need it back you can use obj = JSON.parse(input.value)

The JSON object is available on modern browsers or you can use the json2.js library from json.org

Use this line of code:

Thread.sleep(1000);

It will sleep for 1 second.

Can be pretty easily done assuming you're using jQuery and css3:

http://jsfiddle.net/S7JDU/8/

HTML:

<div id="clicker">Click Here</div>
<div id="rotating"></div>

CSS:

#clicker { 
    width: 100px; 
    height: 100px; 
    background-color: Green; 
}

#rotating { 
    width: 100px; 
    height: 100px; 
    background-color: Red; 
    margin-top: 50px; 
    -webkit-transition: all 0.3s ease-in-out;
    -moz-transition: all 0.3s ease-in-out;
    -o-transition: all 0.3s ease-in-out;
    transition: all 0.3s ease-in-out;
}

.rotated { 
    transform:rotate(25deg); 
    -webkit-transform:rotate(25deg); 
    -moz-transform:rotate(25deg); 
    -o-transform:rotate(25deg); 
}

JS:

$(document).ready(function() {
    $('#clicker').click(function() {
        $('#rotating').toggleClass('rotated');
    });
});

You would be best off using collections.defaultdict (added in Python 2.5). This allows you to specify the default object type of a missing key (such as a list).

So instead of creating a key if it doesn't exist first and then appending to the value of the key, you cut out the middle-man and just directly append to non-existing keys to get the desired result.

A quick example using your data:

>>> from collections import defaultdict
>>> data = [(2010, 2), (2009, 4), (1989, 8), (2009, 7)]
>>> d = defaultdict(list)
>>> d
defaultdict(<type 'list'>, {})
>>> for year, month in data:
...     d[year].append(month)
... 
>>> d
defaultdict(<type 'list'>, {2009: [4, 7], 2010: [2], 1989: [8]})

This way you don't have to worry about whether you've seen a digit associated with a year or not. You just append and forget, knowing that a missing key will always be a list. If a key already exists, then it will just be appended to.

while u write R. you are referring to the R.java class created by eclipse, use getResources().getString() and pass the id of the resource from which you are trying to read inside the getString() method.

Example : String[] yourStringArray = getResources().getStringArray(R.array.Your_array);

There's a free trial for 100 minutes on https://browserling.com and you can test on Safari v7.0 during the trial period.

I started out with playing all the visible videos, but old phones weren't performing well. So right now I play the one video that's closest to the center of the window and pause the rest. Vanilla JS. You can pick which algorithm you prefer.

//slowLooper(playAllVisibleVideos);
slowLooper(playVideoClosestToCenter);

function isVideoPlaying(elem) {
    if (elem.paused || elem.ended || elem.readyState < 2) {
        return false;
    } else {
        return true;
    }
}
function isScrolledIntoView(el) {
    var elementTop = el.getBoundingClientRect().top;
    var elementBottom = el.getBoundingClientRect().bottom;
    var isVisible = elementTop < window.innerHeight && elementBottom >= 0;
    return isVisible;
}
function playVideoClosestToCenter() {
    var vids = document.querySelectorAll('video');
    var smallestDistance = null;
    var smallestDistanceI = null;
    for (var i = 0; i < vids.length; i++) {
        var el = vids[i];
        var elementTop = el.getBoundingClientRect().top;
        var elementBottom = el.getBoundingClientRect().bottom;
        var elementCenter = (elementBottom + elementTop) / 2.0;
        var windowCenter = window.innerHeight / 2.0;
        var distance = Math.abs(windowCenter - elementCenter);
        if (smallestDistance === null || distance < smallestDistance) {
            smallestDistance = distance;
            smallestDistanceI = i;
        }
    }
    if (smallestDistanceI !== null) {
        vids[smallestDistanceI].play();
        for (var i = 0; i < vids.length; i++) {
            if (i !== smallestDistanceI) {
                vids[i].pause();
            }
        }
    }
}
function playAllVisibleVideos(timestamp) {
    // This fixes autoplay for safari
    var vids = document.querySelectorAll('video');
    for (var i = 0; i < vids.length; i++) {
        if (isVideoPlaying(vids[i]) && !isScrolledIntoView(vids[i])) {
            vids[i].pause();
        }
        if (!isVideoPlaying(vids[i]) && isScrolledIntoView(vids[i])) {
            vids[i].play();
        }
    }
}
function slowLooper(cb) {
    // Throttling requestAnimationFrame to a few fps so we don't waste cpu on this
    // We could have listened to scroll+resize+load events which move elements
    // but that would have been more complicated.
    function repeats() {
        cb();
        setTimeout(function() {
            window.requestAnimationFrame(repeats);
        }, 200);

    repeats();

I actually had an easy workaround on this one in which I nearly scratch my head on how to make it work. hahah!

Well, first I downloaded Bootstrap (the compiled css and js version).

Then I pasted all the bootstrap css files to the app/assets/stylesheets/.

And then I pasted all the bootstrap js files to the app/assets/javascripts/.

I reloaded the page and wallah! I just added bootstrap in my RoR!

Yes, it is possible:

git clone https://github.com/pitosalas/st3_packages Packages 

You can specify the local root directory when using git clone.

<directory> 

The name of a new directory to clone into.
The "humanish" part of the source repository is used if no directory is explicitly given (repo for /path/to/repo.git and foo for host.xz:foo/.git).
Cloning into an existing directory is only allowed if the directory is empty.

As Chris comments, you can then rename that top directory.
Git only cares about the .git within said top folder, which you can get with various commands:

git rev-parse --show-toplevel git rev-parse --git-dir 

Solution 1: Log stdout AND stderr concurrently in realtime

A simple solution which logs both stdout AND stderr concurrently, line-by-line in realtime into a log file.

import subprocess as sp
from concurrent.futures import ThreadPoolExecutor


def log_popen_pipe(p, stdfile):

    with open("mylog.txt", "w") as f:

        while p.poll() is None:
            f.write(stdfile.readline())
            f.flush()

        # Write the rest from the buffer
        f.write(stdfile.read())


with sp.Popen(["ls"], stdout=sp.PIPE, stderr=sp.PIPE, text=True) as p:

    with ThreadPoolExecutor(2) as pool:
        r1 = pool.submit(log_popen_pipe, p, p.stdout)
        r2 = pool.submit(log_popen_pipe, p, p.stderr)
        r1.result()
        r2.result()

Solution 2: A function read_popen_pipes() that allows you to iterate over both pipes (stdout/stderr), concurrently in realtime

import subprocess as sp
from queue import Queue, Empty
from concurrent.futures import ThreadPoolExecutor


def enqueue_output(file, queue):
    for line in iter(file.readline, ''):
        queue.put(line)
    file.close()


def read_popen_pipes(p):

    with ThreadPoolExecutor(2) as pool:
        q_stdout, q_stderr = Queue(), Queue()

        pool.submit(enqueue_output, p.stdout, q_stdout)
        pool.submit(enqueue_output, p.stderr, q_stderr)

        while True:

            if p.poll() is not None and q_stdout.empty() and q_stderr.empty():
                break

            out_line = err_line = ''

            try:
                out_line = q_stdout.get_nowait()
                err_line = q_stderr.get_nowait()
            except Empty:
                pass

            yield (out_line, err_line)

# The function in use:

with sp.Popen(["ls"], stdout=sp.PIPE, stderr=sp.PIPE, text=True) as p:

    for out_line, err_line in read_popen_pipes(p):
        print(out_line, end='')
        print(err_line, end='')

    p.poll()

In your js/ts file for the html that will be hovered

@Output() elemHovered: EventEmitter<any> = new EventEmitter<any>();
onHoverEnter(): void {
    this.elemHovered.emit([`The button was entered!`,this.event]);
}

onHoverLeave(): void {
    this.elemHovered.emit([`The button was left!`,this.event])
}

In your HTML that will be hovered

 (mouseenter) = "onHoverEnter()" (mouseleave)="onHoverLeave()"

In your js/ts file that will receive info of the hovering

elemHoveredCatch(d): void {
    console.log(d)
}

In your HTML element that is connected with catching js/ts file

(elemHovered) = "elemHoveredCatch($event)"

As of Visual Studio 2015 you can also do this with Interpolated Strings (its a compiler trick, so it doesn't matter which version of the .net framework you target).

string value = "String goes here";
string txt1 = $"{value,20}";
string txt2 = $"{value,-20}";

You need to wrap the text in a div element and include the absolutely positioned element inside of it.

<div class="container">
    <div class="inner">
        <div class="full-height"></div>
        [Your text here]
    </div>
</div>

Css:

.inner: { position: relative; height: auto; }
.full-height: { height: 100%; }

Setting the inner div's position to relative makes the absolutely position elements inside of it base their position and height on it rather than on the .container div, which has a fixed height. Without the inner, relatively positioned div, the .full-height div will always calculate its dimensions and position based on .container.

My preferred way is a bit long, but has some advantages over the other answers:

• It can combine an indefinite number of arrays at once
• It can combine arrays with non-arrays (objects, strings, integers, etc.)
• It accounts for the possibility that one or more of the arrays may contain objects
• It allows the user to choose the base of the new array (0, 1, etc.)

Here it is:

Function combineArrays(ByVal toCombine As Variant, Optional ByVal newBase As Long = 1)
'Combines an array of one or more 1d arrays, objects, or values into a single 1d array
'newBase parameter indicates start position of new array (0, 1, etc.)
'Example usage:
    'combineArrays(Array(Array(1,2,3),Array(4,5,6),Array(7,8))) -> Array(1,2,3,4,5,6,7,8)
    'combineArrays(Array("Cat",Array(2,3,4))) -> Array("Cat",2,3,4)
    'combineArrays(Array("Cat",ActiveSheet)) -> Array("Cat",ActiveSheet)
    'combineArrays(Array(ThisWorkbook)) -> Array(ThisWorkbook)

        Exit Function
    End If

    Dim i As Long

    newMax = 0

    For i = LBound(toCombine) To UBound(toCombine)

You can do injection on Directives, and it looks just like it does everywhere else.

app.directive('changeIt', ['myData', function(myData){
    return {
        restrict: 'C',
        link: function (scope, element, attrs) {
            scope.name = myData.name;
        }
    }
 }]);

if your SQL query is like this

SELECT col-1, col-2 FROM tableName WHERE col-1=apple,col-2=mango
GROUPBY col-3 HAVING Count(col-4) > 5  ORDERBY col-2 DESC LIMIT 15;

Then for query() method, we can do as:-

String table = "tableName";
String[] columns = {"col-1", "col-2"};
String selection = "col-1 =? AND col-2=?";       
String[] selectionArgs = {"apple","mango"};
String groupBy =col-3;
String having =" COUNT(col-4) > 5";
String orderBy = "col-2 DESC";
String limit = "15";

query(tableName, columns, selection, selectionArgs, groupBy, having, orderBy, limit);

Simple example from: http://www.longtailvideo.com/blog/26517/using-the-browsers-new-html5-fullscreen-capabilities/

<script type="text/javascript">
  function goFullscreen(id) {
    // Get the element that we want to take into fullscreen mode
    var element = document.getElementById(id);

    // These function will not exist in the browsers that don't support fullscreen mode yet, 
    // so we'll have to check to see if they're available before calling them.

    if (element.mozRequestFullScreen) {
      // This is how to go into fullscren mode in Firefox
      // Note the "moz" prefix, which is short for Mozilla.
      element.mozRequestFullScreen();
    } else if (element.webkitRequestFullScreen) {
      // This is how to go into fullscreen mode in Chrome and Safari
      // Both of those browsers are based on the Webkit project, hence the same prefix.
      element.webkitRequestFullScreen();
   }
   // Hooray, now we're in fullscreen mode!
  }
</script>

<img class="video_player" src="image.jpg" id="player"></img>
<button onclick="goFullscreen('player'); return false">Click Me To Go Fullscreen! (For real)</button>

You can also use the 'sed' function that's part of ShellJS ...

 $ npm install [-g] shelljs


 require('shelljs/global');
 sed('-i', 'search_pattern', 'replace_pattern', file);

Visit ShellJs.org for more examples.

Wrong syntax. You can't compare a Boolean to a string like "false" or "true". In your case, just test it's inverse:

if(!ValidateForm()) { ...

You could test against the constant false, but it's rather ugly and generally frowned upon:

if(ValidateForm() == false) { ...

as per @cyberbikepunk answer pycharm supports Anaconda since pycharm5!

Have a look how easy is to add an environment:

All this talk about collation seem a bit over-complicated. Why not just use something like:

IF UPPER(@@VERSION) NOT LIKE '%AZURE%'

Then your check is case insensitive whatever the collation

If you don't know the size, you can use:

std::sort(v, v + sizeof v / sizeof v[0]);

Even if you do know the size, it's a good idea to code it this way as it will reduce the possibility of a bug if the array size is changed later.

In my case, I had copied some code from another project that was using Automapper - took me ages to work that one out. Just had to add automapper nuget package to project.

This approach is not correct beacuse of Google Server Overload. For more informations see https://gis.stackexchange.com/questions/15052/how-to-avoid-google-map-geocode-limit#answer-15365

By the way, if you wish to proceed anyway, here you can find a code that let you load multiple markers ajax sourced on google maps avoiding OVER_QUERY_LIMIT error.

I've tested on my onw server and it works!:

       lng: 12.337646,
    });

I realise this is an old post but this might benefit somebody who, like me, has come to this page from a google search and is at their wits end.

None of the other answers given here worked for me and I had already given up hope, but today I was searching for a solution to another similar problem with divs, which I found answered multiple times on SO. The accepted answer worked for my div, and I had the sudden notion to try it for my previous textbox issue - and it worked! The solution:

add box-sizing: border-box to the style of the textbox.

To add this to all multi-line textboxes using CSS, add the following to your style sheet:

textarea
{
  box-sizing: border-box;
}

Thanks to thirtydot for the solution at

width: 100%-padding?

and

Content of div is longer then div itself when width is set to 100%?

I feel I want answer this question even there some good answers ,

according to documentation TransformationMethod do our mission

TransformationMethod

TextView uses TransformationMethods to do things like replacing the characters of passwords with dots, or keeping the newline characters from causing line breaks in single-line text fields.

Notice I use butter knife, but its the same if user check show password

@OnCheckedChanged(R.id.showpass)
    public void onChecked(boolean checked){
        if(checked){
            et_password.setTransformationMethod(null);
        }else {
            et_password.setTransformationMethod(new PasswordTransformationMethod());
            
        }
       // cursor reset his position so we need set position to the end of text
        et_password.setSelection(et_password.getText().length());
    }

Try

public bool IsDivisible(int x, int n)
{
   return (x % n) == 0;
}

The modulus operator % returns the remainder after dividing x by n which will always be 0 if x is divisible by n.

For more information, see the % operator on MSDN.

Modifying styles directly in range or cells did not work for me. But the idea to:

1. create a separate style
2. apply all the necessary style property values
3. set the style's name to the Style property of the range

, given in MSDN How to: Programmatically Apply Styles to Ranges in Workbooks did the job.

For example:

var range = worksheet.Range[string.Format("A{0}:C{0}", rowIndex++)];
range.Merge();
range.Value = "some value";

var style = workbook.AddStyle();
style.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignLeft;

range.Style = style.Name;

You have misunderstood the Python list object. It is similar to a C pointer-array. It does not actually "copy" the object which you append to it. Instead, it just store a "pointer" to that object.

Try the following code:

>>> d={}
>>> dlist=[]
>>> for i in xrange(0,3):
    d['data']=i
    dlist.append(d)
    print(d)

{'data': 0}
{'data': 1}
{'data': 2}
>>> print(dlist)
[{'data': 2}, {'data': 2}, {'data': 2}]

So why is print(dlist) not the same as print(d)?

The following code shows you the reason:

>>> for i in dlist:
    print "the list item point to object:", id(i)

the list item point to object: 47472232
the list item point to object: 47472232
the list item point to object: 47472232

So you can see all the items in the dlist is actually pointing to the same dict object.

The real answer to this question will be to append the "copy" of the target item, by using d.copy().

>>> dlist=[]
>>> for i in xrange(0,3):
    d['data']=i
    dlist.append(d.copy())
    print(d)

{'data': 0}
{'data': 1}
{'data': 2}
>>> print dlist
[{'data': 0}, {'data': 1}, {'data': 2}]

Try the id() trick, you can see the list items actually point to completely different objects.

>>> for i in dlist:
    print "the list item points to object:", id(i)

the list item points to object: 33861576
the list item points to object: 47472520
the list item points to object: 47458120

Introduction

The ServletContext#getRealPath() is intented to convert a web content path (the path in the expanded WAR folder structure on the server's disk file system) to an absolute disk file system path.

The "/" represents the web content root. I.e. it represents the web folder as in the below project structure:

YourWebProject
 |-- src
 |    :
 |
 |-- web
 |    |-- META-INF
 |    |    `-- MANIFEST.MF
 |    |-- WEB-INF
 |    |    `-- web.xml
 |    |-- index.jsp
 |    `-- login.jsp
 :    

So, passing the "/" to getRealPath() would return you the absolute disk file system path of the /web folder of the expanded WAR file of the project. Something like /path/to/server/work/folder/some.war/ which you should be able to further use in File or FileInputStream.

Note that most starters don't seem to see/realize that you can actually pass the whole web content path to it and that they often use

String absolutePathToIndexJSP = servletContext.getRealPath("/") + "index.jsp"; // Wrong!

or even

String absolutePathToIndexJSP = servletContext.getRealPath("") + "index.jsp"; // Wronger!

instead of

String absolutePathToIndexJSP = servletContext.getRealPath("/index.jsp"); // Right!

Don't ever write files in there

Also note that even though you can write new files into it using FileOutputStream, all changes (e.g. new files or edited files) will get lost whenever the WAR is redeployed; with the simple reason that all those changes are not contained in the original WAR file. So all starters who are attempting to save uploaded files in there are doing it wrong.

Moreover, getRealPath() will always return null or a completely unexpected path when the server isn't configured to expand the WAR file into the disk file system, but instead into e.g. memory as a virtual file system.

getRealPath() is unportable; you'd better never use it

Use getRealPath() carefully. There are actually no sensible real world use cases for it. Based on my 20 years of Java EE experience, there has always been another way which is much better and more portable than getRealPath().

If all you actually need is to get an InputStream of the web resource, better use ServletContext#getResourceAsStream() instead, this will work regardless of the way how the WAR is expanded. So, if you for example want an InputStream of index.jsp, then do not do:

InputStream input = new FileInputStream(servletContext.getRealPath("/index.jsp")); // Wrong!

But instead do:

InputStream input = servletContext.getResourceAsStream("/index.jsp"); // Right!

Or if you intend to obtain a list of all available web resource paths, use ServletContext#getResourcePaths() instead.

Set<String> resourcePaths = servletContext.getResourcePaths("/");

You can obtain an individual resource as URL via ServletContext#getResource(). This will return null when the resource does not exist.

URL resource = servletContext.getResource(path);

Or if you intend to save an uploaded file, or create a temporary file, then see the below "See also" links.

See also:

• getResourceAsStream() vs FileInputStream

Heres how this code looks:

Heres my drag and drop code:

var boxView = UIView()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.

    view.backgroundColor = UIColor.blackColor()
    addSavingPhotoView()

    //Custom button to test this app
    var button = UIButton(frame: CGRect(x: 20, y: 20, width: 20, height: 20))
    button.backgroundColor = UIColor.redColor()
    button.addTarget(self, action: "buttonAction:", forControlEvents: UIControlEvents.TouchUpInside)

    view.addSubview(button)
}

func addSavingPhotoView() {
    // You only need to adjust this frame to move it anywhere you want
    boxView = UIView(frame: CGRect(x: view.frame.midX - 90, y: view.frame.midY - 25, width: 180, height: 50))
    boxView.backgroundColor = UIColor.whiteColor()
    boxView.alpha = 0.8
    boxView.layer.cornerRadius = 10

    //Here the spinnier is initialized
    var activityView = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.Gray)
    activityView.frame = CGRect(x: 0, y: 0, width: 50, height: 50)
    activityView.startAnimating()

    var textLabel = UILabel(frame: CGRect(x: 60, y: 0, width: 200, height: 50))
    textLabel.textColor = UIColor.grayColor()
    textLabel.text = "Saving Photo"

    boxView.addSubview(activityView)
    boxView.addSubview(textLabel)

    view.addSubview(boxView)
}

func buttonAction(sender:UIButton!) {
    //When button is pressed it removes the boxView from screen
    boxView.removeFromSuperview()
}

Here is an open source version of this: https://github.com/goktugyil/CozyLoadingActivity

"UPDATE TableName SET TableField = TableField + 1 WHERE SomeFilterField = @ParameterID"

A better and more organized way of overriding Devise controllers and views using namespaces:

Create the following folders:

app/controllers/my_devise
app/views/my_devise

Put all controllers that you want to override into app/controllers/my_devise and add MyDevise namespace to controller class names. Registrations example:

# app/controllers/my_devise/registrations_controller.rb
class MyDevise::RegistrationsController < Devise::RegistrationsController

  ...

  def create
    # add custom create logic here
  end

  ...    

end 

Change your routes accordingly:

devise_for :users,
           :controllers  => {
             :registrations => 'my_devise/registrations',
             # ...
           }

Copy all required views into app/views/my_devise from Devise gem folder or use rails generate devise:views, delete the views you are not overriding and rename devise folder to my_devise.

Tested with Xcode 9 (edit also tested on 11 / 12 Beta 2) and Swift 4 (edit: also tested on 5.2)

The asker of the original question has solved their problem. I am adding this answer as a mini self contained example project for others who are trying to do the same thing.

The finished project should look like this:

Create a new project

It can be just a Single View Application.

Add the code

Add a new Swift file to your project. Name it MyCustomCell.swift. This class will hold the outlets for the views that you add to your cell in the storyboard.

import UIKit
class MyCustomCell: UITableViewCell {
    @IBOutlet weak var myView: UIView!
    @IBOutlet weak var myCellLabel: UILabel!
}

We will connect these outlets later.

Open ViewController.swift and make sure you have the following content:

import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
    
    // These strings will be the data for the table view cells
    let animals: [String] = ["Horse", "Cow", "Camel", "Sheep", "Goat"]
    
    // These are the colors of the square views in our table view cells.
    // In a real project you might use UIImages.
    let colors = [UIColor.blue, UIColor.yellow, UIColor.magenta, UIColor.red, UIColor.brown]
    
    // Don't forget to enter this in IB also
    let cellReuseIdentifier = "cell"
    
    @IBOutlet var tableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        tableView.delegate = self
        tableView.dataSource = self
    }
    
    // number of rows in table view
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.animals.count
    }
    
    // create a cell for each table view row
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        
        let cell:MyCustomCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as! MyCustomCell
        
        cell.myView.backgroundColor = self.colors[indexPath.row]
        cell.myCellLabel.text = self.animals[indexPath.row]
        
        return cell
    }
    
    // method to run when table view cell is tapped
    func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        print("You tapped cell number \(indexPath.row).")
    }
}

Setup the storyboard

Add a Table View to your view controller and use auto layout to pin it to the four sides of the View Controller. Then drag a Table View Cell onto the Table View. And then drag a View and a Label onto the Prototype cell. (You may need to select the Table View Cell and manually set the Row Height to something taller in the Size inspector so that you have more room to work with.) Use auto layout to fix the View and the Label how you want them arranged within the content view of the Table View Cell. For example, I made my View be 100x100.

Other IB settings

Custom class name and Identifier

Select the Table View Cell and set the custom class to be MyCustomCell (the name of the class in the Swift file we added). Also set the Identifier to be cell (the same string that we used for the cellReuseIdentifier in the code above.

Hook Up the Outlets

• Control drag from the Table View in the storyboard to the tableView variable in the ViewController code.
• Do the same for the View and the Label in your Prototype cell to the myView and myCellLabel variables in the MyCustomCell class.

Finished

That's it. You should be able to run your project now.

Notes

• The colored views that I used here could be replaced with anything. An obvious example would be a UIImageView.
• If you are just trying to get a TableView to work, see this even more basic example.
• If you need a Table View with variable cell heights, see this example.

You probably did not install MySQL via yum? The version of MySQLDB in the repository is tied to the version of MySQL in the repository. The versions need to match.

Your choices are:

1. Install the RPM version of MySQL.
2. Compile MySQLDB to your version of MySQL.

It is much easier to do:

Button button = new Button();
button.Click += delegate
{
   // Your code
};

Place this meta tag after head tag

<meta http-equiv="x-ua-compatible" content="IE=edge">

Here is the example:

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

no rows selected

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

D
-
X

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

To force a reload of the php.ini you should restart apache.

Try sudo service apache2 restart from the command line. Or sudo /etc/init.d/apache2 restart

The quickest way

path = ThisWorkbook.Path & "\"

Here is a simple solution that strips HTML tags and decodes HTML entities based on the amazingly fast lxml library:

from lxml import html

def strip_html(s):
    return str(html.fromstring(s).text_content())

strip_html('Ein <a href="">sch&ouml;ner</a> Text.')  # Output: Ein schöner Text.

Why nobody use the event object returned by jQuery on scroll ?

$window.on('scroll', function (event) {
    console.group('Scroll');
    console.info('Scroll event:', event);
    console.info('Position:', this.pageYOffset);
    console.info('Direction:', event.originalEvent.dir); // Here is the direction
    console.groupEnd();
});

I'm using chromium and I didn't checked on other browsers if they have the dir property.

This is a tricky question.

There a set of problems about file permissions. If you can do this at the command line

$ sudo chown myaccount /path/to/file

then you have a standard permissions problem. Make sure you own the file and have permission to modify the directory.

If you cannnot get permissions, then you have probably mounted a FAT-32 filesystem. If you ls -l the file, and you find it is owned by root and a member of the "plugdev" group, then you are certain its the issue. FAT-32 permissions are set at the time of mounting, using the line of /etc/fstab file. You can set the uid/gid of all the files like this:

UUID=C14C-CE25  /big            vfat    utf8,umask=007,uid=1000,gid=1000 0       1

Also, note that the FAT-32 won't take symbolic links.

Wrote the whole thing up at http://www.charlesmerriam.com/blog/2009/12/operation-not-permitted-and-the-fat-32-system/

Try this:

new ClassPathXmlApplicationContext("file:src/main/resources/beans.xml");

file: preffix point to file system resources, not classpath.

file path can be relative or system (/home/user/Work/src...)

An alternative is to use String.format:

double[] arr = { 23.59004,
    35.7,
    3.0,
    9
};

for ( double dub : arr ) {
  System.out.println( String.format( "%.2f", dub ) );
}

output:

23.59
35.70
3.00
9.00

You could also use System.out.format (same method signature), or create a java.util.Formatter which works in the same way.

I changed Graphics to Software, Intel x86 Emulator was already installed and also restarted the PC. Nothing worked. It was the Hyper-V issue. I had turned it off for VMWare. I turned it on and restarted the PC and emulator worked. So please try Hyper-V.

Use Array.GetUpperBound(0). Array.Length contains the number of items in the array, so reading Length -1 only works on the assumption that the array is zero based.

The following worked for me

const conString = "postgres://YourUserName:YourPassword@YourHostname:5432/YourDatabaseName";

Internal Fragmentation Internal fragmentation occurs when the memory allocator leaves extra space empty inside of a block of memory that has been allocated for a client. This usually happens because the processor’s design stipulates that memory must be cut into blocks of certain sizes -- for example, blocks may be required to be evenly be divided by four, eight or 16 bytes. When this occurs, a client that needs 57 bytes of memory, for example, may be allocated a block that contains 60 bytes, or even 64. The extra bytes that the client doesn’t need go to waste, and over time these tiny chunks of unused memory can build up and create large quantities of memory that can’t be put to use by the allocator. Because all of these useless bytes are inside larger memory blocks, the fragmentation is considered internal.

External Fragmentation External fragmentation happens when the memory allocator leaves sections of unused memory blocks between portions of allocated memory. For example, if several memory blocks are allocated in a continuous line but one of the middle blocks in the line is freed (perhaps because the process that was using that block of memory stopped running), the free block is fragmented. The block is still available for use by the allocator later if there’s a need for memory that fits in that block, but the block is now unusable for larger memory needs. It cannot be lumped back in with the total free memory available to the system, as total memory must be contiguous for it to be useable for larger tasks. In this way, entire sections of free memory can end up isolated from the whole that are often too small for significant use, which creates an overall reduction of free memory that over time can lead to a lack of available memory for key tasks.
