Just to augment the other answers from a different angle.

If you want to reuse hashcode(s) from 'above' and derive new ones using your class' immutatable state, then a call to super will work. While this may/may not cascade all the way up to Object (i.e. some ancestor may not call super), it will allow you to derive hashcodes by reuse.

@Override
public int hashCode() {
    int ancestorHash = super.hashCode();
    // now derive new hash from ancestorHash plus immutable instance vars (id fields)
}

There's simpler solution for that - set fixed height of card elements - header and body. This way, we can set resposive layout with standard boostrap column grid.

Here is my example: http://codeply.com/go/RHDawRSBol

 <div class="card-deck text-center">
    <div class="col-sm-6 col-md-4 col-lg-3">
        <div class="card mb-4">
            <img class="card-img-top img-fluid" src="//placehold.it/500x280" alt="Card image cap">
            <div class="card-body" style="height: 20rem">
                <h4 class="card-title">1 Card title</h4>
                <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
                <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
            </div>
        </div>

Select * from table1 where lastest_date=(select Max(latest_date) from table1 where user=yourUserName)

Inner Query will return the latest date for the current user, Outer query will pull all the data according to the inner query result.

None of the answers posted here worked for me.

In my case the problem was, by the one hand, that the .conf file (/etc/apache2/sites-available/default-ssl.conf or /etc/apache2/sites-available/000-default.conf) did not contain the directive AllowOverride All for the site directory, which caused the .htaccess to not been processed. To solve this, add:

<Directory /var/www/html/>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
</Directory>

On the other hand, the problem was that the .htaccess was created by the root user, and therefore the apache user could not read it. So, changing the file owner solved definitely the problem:

chown www-data:www-data .htaccess

After some tries, I think the default behavior is correct and there is nothing to hack.

The only trick is: if your post method argument is string like below, you should send a plain string with double quotes in the body (when using ajax or postman), e.g.,

//send "{\"a\":1}" in body to me, note the outer double quotes
[HttpPost("api1")]
public String PostMethod1([FromBody]string value)
{
    return "received " + value; //  "received {\"a\":1}"
}

Otherwise if you send a json string in the post body without outer double quotes and escaped inner quotes, then it should be able to be parsed to the model class (the argument type), e.g., {"a":1, "b":2}

public class MyPoco{
    public int a;
    public int b;
}

//send {"a":1, "b":2} in body to me
[HttpPost("api2")]
public String PostMethod2([FromBody]MyPoco value)
{
    return "received " + value.ToString();  //"received your_namespace+MyPoco"
}

This solution is somewhat similar to the answer by Erwin Brandstetter, but uses only the sql language.

Not all PostgreSQL installations has the plpqsql language by default, this means you may have to call CREATE LANGUAGE plpgsql before creating the function, and afterwards have to remove the language again, to leave the database in the same state as it was before (but only if the database did not have the plpgsql language to begin with). See how the complexity grows?

Adding the plpgsql may not be issue if you are running your script locally, however, if the script is used to set up schema at a customer it may not be desirable to leave changes like this in the customers database.

This solution is inspired by a post by Andreas Scherbaum.

There is no native version of Visual Studio for Mac OS X.

Almost all versions of Visual Studio have a Garbage rating on Wine's application database, so Wine isn't an option either, sadly.

If you want to filter out only your app's activities currently running/paused, you can use this command:

adb shell dumpsys activity activities | grep 'Hist #' | grep 'YOUR_PACKAGE_NAME'

For example:

adb shell dumpsys activity activities | grep 'Hist #' | grep 'com.supercell.clashroyale'

The output will be something like:

* Hist #2: ActivityRecord{26ba44b u10 com.supercell.clashroyale/StartActivity t27770}
* Hist #1: ActivityRecord{2f3a0236 u10 com.supercell.clashroyale/SomeActivity t27770}
* Hist #0: ActivityRecord{20bbb4ae u10 com.supercell.clashroyale/OtherActivity t27770}

Do notice that the output shows the actual stack of activities i.e. the topmost activity is the one that is currently being displayed.

I might misunderstand, but are you trying to delete files newly ignored or do you want to ignore new modifications to these files ? In this case, the thing is working.

If you want to delete ignored files previously commited, then use

git rm –cached `git ls-files -i –exclude-standard`
git commit -m 'clean up'

If SQL Server Service is running as Local System, than make sure that the folder containing databases should have FULL CONTROL PERMISSION for the Local System account.

This worked for me.

I followed to the help page of memory.limit and found out that on my computer R by default can use up to ~ 1.5 GB of RAM and that the user can increase this limit. Using the following code,

>memory.limit()
[1] 1535.875
> memory.limit(size=1800)

helped me to solve my problem.

Before enabling the My Location layer, you must request location permission from the user. This sample does not include a request for location permission.

To simplify, in terms of lines of code, the request for the location permit can be made using the library EasyPermissions.

Then following the example of the official documentation of The My Location Layer my code works as follows for all versions of Android that contain Google services.

1. Create an activity that contains a map and implements the interfaces OnMyLocationClickListener y OnMyLocationButtonClickListener.
2. Define in app/build.gradle implementation 'pub.devrel:easypermissions:2.0.1'

3. Forward results to EasyPermissions within method onRequestPermissionsResult()

   EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);

4. Request permission and operate according to the user's response with requestLocationPermission()

5. Call requestLocationPermission() and set the listeners to onMapReady().

MapsActivity.java

public class MapsActivity extends FragmentActivity implements 
    OnMapReadyCallback,
    GoogleMap.OnMyLocationClickListener,
    GoogleMap.OnMyLocationButtonClickListener {

    private final int REQUEST_LOCATION_PERMISSION = 1;

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap googleMap) {
        mMap = googleMap;

        requestLocationPermission();
        mMap.setOnMyLocationButtonClickListener(this);
        mMap.setOnMyLocationClickListener(this);
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        // Forward results to EasyPermissions
        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
    }

    @SuppressLint("MissingPermission")
    @AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
    public void requestLocationPermission() {
        String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
        if(EasyPermissions.hasPermissions(this, perms)) {
            mMap.setMyLocationEnabled(true);
            Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
        }
        else {
            EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
        }
    }

    @Override
    public boolean onMyLocationButtonClick() {
        Toast.makeText(this, "MyLocation button clicked", Toast.LENGTH_SHORT).show();
        return false;
    }

    @Override
    public void onMyLocationClick(@NonNull Location location) {
        Toast.makeText(this, "Current location:\n" + location, Toast.LENGTH_LONG).show();
    }
}

You can't change CSS properties directly with jQuery. But you can achieve the same effect in at least two ways.

Dynamically Load CSS from a File

function updateStyleSheet(filename) {
    newstylesheet = "style_" + filename + ".css";

    if ($("#dynamic_css").length == 0) {
        $("head").append("<link>")
        css = $("head").children(":last");

        css.attr({
          id: "dynamic_css",
          rel:  "stylesheet",
          type: "text/css",
          href: newstylesheet
        });
    } else {
        $("#dynamic_css").attr("href",newstylesheet);
    }
}

The example above is copied from:

• How To Switch CSS Files On-The-Fly Using jQuery

Dynamically Add a Style Element

$("head").append('<style type="text/css"></style>');
var newStyleElement = $("head").children(':last');
newStyleElement.html('.red{background:green;}');

The example code is copied from this JSFiddle fiddle originally referenced by Alvaro in their comment.

I have added in Application Class

@Bean
@ConfigurationProperties("app.datasource")
public DataSource dataSource() {
    return DataSourceBuilder.create().build();
}

application.properties I have added

app.datasource.url=jdbc:mysql://localhost/test
app.datasource.username=dbuser
app.datasource.password=dbpass
app.datasource.pool-size=30

Just use the max function and group function

    select max(taskhistory.id) as id from taskhistory
            group by taskhistory.taskid
            order by taskhistory.datum desc

This is the best way. Please note Array is an object in NET so you need to check for null before.

Double check if you have set and initial value for int and decimal values to be printed.

This sample is printing an empty line

declare @Number INT
print 'The number is : ' + CONVERT(VARCHAR, @Number)

And this sample is printing -> The number is : 1

declare @Number INT = 1
print 'The number is : ' + CONVERT(VARCHAR, @Number)

I found the solution:

function onClick(e) {alert(this.getLatLng());}

used the method getLatLng() of the marker

The Singleton:

package com.domain.packagename;

import android.content.Context;

/**
 * Created by Versa on 10.09.15.
 */
public class ApplicationContextSingleton {
    private static PrefsContextSingleton mInstance;
    private Context context;

    public static ApplicationContextSingleton getInstance() {
        if (mInstance == null) mInstance = getSync();
        return mInstance;
    }

    private static synchronized ApplicationContextSingleton getSync() {
        if (mInstance == null) mInstance = new PrefsContextSingleton();
        return mInstance;
    }

    public void initialize(Context context) {
        this.context = context;
    }

    public Context getApplicationContext() {
        return context;
    }

}

Initialize the Singleton in your Application subclass:

package com.domain.packagename;

import android.app.Application;

/**
 * Created by Versa on 25.08.15.
 */
public class mApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        ApplicationContextSingleton.getInstance().initialize(this);
    }
}

If I´m not wrong, this gives you a hook to applicationContext everywhere, call it with ApplicationContextSingleton.getInstance.getApplicationContext(); You shouldn´t need to clear this at any point, as when application closes, this goes with it anyway.

Remember to update AndroidManifest.xml to use this Application subclass:

<?xml version="1.0" encoding="utf-8"?>

<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.domain.packagename"
    >

<application
    android:allowBackup="true"
    android:name=".mApplication" <!-- This is the important line -->
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:icon="@drawable/app_icon"
    >

Now you should be able to use ApplicationContextSingleton.getInstance().getApplicationContext().getResources() from anywhere, also the very few places where application subclasses can´t.

Please let me know if you see anything wrong here, thank you. :)

I tried the program below and saw different string each time

package main

import (
    "fmt"
    "math/rand"
    "time"
)

func RandomString(count int){
  rand.Seed(time.Now().UTC().UnixNano()) 
  for(count > 0 ){
    x := Random(65,91)
    fmt.Printf("%c",x)
    count--;
  }
}

func Random(min, max int) (int){
 return min+rand.Intn(max-min) 
}

func main() {
 RandomString(12)
}

And the output on my console is

D:\james\work\gox>go run rand.go
JFBYKAPEBCRC
D:\james\work\gox>go run rand.go
VDUEBIIDFQIB
D:\james\work\gox>go run rand.go

If you are just getting started with a new project then I would suggest that you use PDO instead of the old odbc_exec() approach. Here is a simple example:

<?php
$bits = 8 * PHP_INT_SIZE;
echo "(Info: This script is running as $bits-bit.)\r\n\r\n";

$connStr = 
        'odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};' .
        'Dbq=C:\\Users\\Gord\\Desktop\\foo.accdb;';

$dbh = new PDO($connStr);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$sql = 
        "SELECT AgentName FROM Agents " .
        "WHERE ID < ? AND AgentName <> ?";
$sth = $dbh->prepare($sql);

// query parameter value(s)
$params = array(
        5,
        'Homer'
        );

$sth->execute($params);

while ($row = $sth->fetch()) {
    echo $row['AgentName'] . "\r\n";
}

NOTE: The above approach is sufficient if you do not need to support Unicode characters above U+00FF. If you do need to support such characters then neither PDO_ODBC nor the old odbc_ functions will work; you'll need to use the solution described in this answer.

Suggestions:

• Create a File object that refers to the already existing file on disk.
• Use a FileWriter object, and use the constructor that takes the File object and a boolean, the latter if true would allow appending text into the File if it exists.
• Then initialize a PrintWriter passing in the FileWriter into its constructor.
• Then call println(...) on your PrintWriter, writing your new text into the file.
• As always, close your resources (the PrintWriter) when you are done with it.
• As always, don't ignore exceptions but rather catch and handle them.
• The close() of the PrintWriter should be in the try's finally block.

e.g.,

  PrintWriter pw = null;

  try {
     File file = new File("fubars.txt");
     FileWriter fw = new FileWriter(file, true);
     pw = new PrintWriter(fw);
     pw.println("Fubars rule!");
  } catch (IOException e) {
     e.printStackTrace();
  } finally {
     if (pw != null) {
        pw.close();
     }
  }

Easy, no?

You can list the attributes of a object with dir() in the shell:

>>> dir(object())
['__class__', '__delattr__', '__doc__', '__format__', '__getattribute__', '__hash__', '__init__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__']

Of course, there is also the inspect module: http://docs.python.org/library/inspect.html#module-inspect

Making strings immutable has many advantages. It provides automatic thread safety, and makes strings behave like an intrinsic type in a simple, effective manner. It also allows for extra efficiencies at runtime (such as allowing effective string interning to reduce resource usage), and has huge security advantages, since it's impossible for an third party API call to change your strings.

StringBuilder was added in order to address the one major disadvantage of immutable strings - runtime construction of immutable types causes a lot of GC pressure and is inherently slow. By making an explicit, mutable class to handle this, this issue is addressed without adding unneeded complication to the string class.

Since .NET 2.0 you can use:

// Indicates whether the specified string is null or an Empty string.
string.IsNullOrEmpty(string value);

Additionally, since .NET 4.0 there's a new method that goes a bit farther:

// Indicates whether a specified string is null, empty, or consists only of white-space characters.
string.IsNullOrWhiteSpace(string value);

There is another way to do XOR:

bool XOR(bool a, bool b)
{
    return (a + b) % 2;
}

Which obviously can be demonstrated to work via:

#include <iostream>

bool XOR(bool a, bool b)
{
    return (a + b) % 2;
}

int main()
{
    using namespace std;
    cout << "XOR(true, true):\t" << XOR(true, true) << endl
         << "XOR(true, false):\t" << XOR(true, false) << endl
         << "XOR(false, true):\t" << XOR(false, true) << endl
         << "XOR(false, false):\t" << XOR(false, false) << endl
         << "XOR(0, 0):\t\t" << XOR(0, 0) << endl
         << "XOR(1, 0):\t\t" << XOR(1, 0) << endl
         << "XOR(5, 0):\t\t" << XOR(5, 0) << endl
         << "XOR(20, 0):\t\t" << XOR(20, 0) << endl
         << "XOR(6, 6):\t\t" << XOR(5, 5) << endl
         << "XOR(5, 6):\t\t" << XOR(5, 6) << endl
         << "XOR(1, 1):\t\t" << XOR(1, 1) << endl;
    return 0;
}

You could also use the RANK function

=RANK(C2,$C$2:$C$7,0)

It would return data like your example:

  | A       | B        | C
1 | name    | position | points
2 | person1 | 1        | 10
3 | person2 | 2        | 9
4 | person3 | 2        | 9
5 | person4 | 2        | 9
6 | person5 | 5        | 8
7 | person6 | 6        | 7

The 'Points' column needs to be sorted into descending order.

Short answer:

use a non-blocking recv(), or a blocking recv() / select() with a very short timeout.

Long answer:

The way to handle socket connections is to read or write as you need to, and be prepared to handle connection errors.

TCP distinguishes between 3 forms of "dropping" a connection: timeout, reset, close.

Of these, the timeout can not really be detected, TCP might only tell you the time has not expired yet. But even if it told you that, the time might still expire right after.

Also remember that using shutdown() either you or your peer (the other end of the connection) may close only the incoming byte stream, and keep the outgoing byte stream running, or close the outgoing stream and keep the incoming one running.

So strictly speaking, you want to check if the read stream is closed, or if the write stream is closed, or if both are closed.

Even if the connection was "dropped", you should still be able to read any data that is still in the network buffer. Only after the buffer is empty will you receive a disconnect from recv().

Checking if the connection was dropped is like asking "what will I receive after reading all data that is currently buffered ?" To find that out, you just have to read all data that is currently bufferred.

I can see how "reading all buffered data", to get to the end of it, might be a problem for some people, that still think of recv() as a blocking function. With a blocking recv(), "checking" for a read when the buffer is already empty will block, which defeats the purpose of "checking".

In my opinion any function that is documented to potentially block the entire process indefinitely is a design flaw, but I guess it is still there for historical reasons, from when using a socket just like a regular file descriptor was a cool idea.

What you can do is:

• set the socket to non-blocking mode, but than you get a system-depended error to indicate the receive buffer is empty, or the send buffer is full
• stick to blocking mode but set a very short socket timeout. This will allow you to "ping" or "check" the socket with recv(), pretty much what you want to do
• use select() call or asyncore module with a very short timeout. Error reporting is still system-specific.

For the write part of the problem, keeping the read buffers empty pretty much covers it. You will discover a connection "dropped" after a non-blocking read attempt, and you may choose to stop sending anything after a read returns a closed channel.

I guess the only way to be sure your sent data has reached the other end (and is not still in the send buffer) is either:

• receive a proper response on the same socket for the exact message that you sent. Basically you are using the higher level protocol to provide confirmation.
• perform a successful shutdow() and close() on the socket

The python socket howto says send() will return 0 bytes written if channel is closed. You may use a non-blocking or a timeout socket.send() and if it returns 0 you can no longer send data on that socket. But if it returns non-zero, you have already sent something, good luck with that :)

Also here I have not considered OOB (out-of-band) socket data here as a means to approach your problem, but I think OOB was not what you meant.

The answer to the question was already posted by the @latemail in the comments above. You can use regular expressions for the second and subsequent arguments of filter like this:

dplyr::filter(df, !grepl("RTB",TrackingPixel))

Since you have not provided the original data, I will add a toy example using the mtcars data set. Imagine you are only interested in cars produced by Mazda or Toyota.

mtcars$type <- rownames(mtcars)
dplyr::filter(mtcars, grepl('Toyota|Mazda', type))

   mpg cyl  disp  hp drat    wt  qsec vs am gear carb           type
1 21.0   6 160.0 110 3.90 2.620 16.46  0  1    4    4      Mazda RX4
2 21.0   6 160.0 110 3.90 2.875 17.02  0  1    4    4  Mazda RX4 Wag
3 33.9   4  71.1  65 4.22 1.835 19.90  1  1    4    1 Toyota Corolla
4 21.5   4 120.1  97 3.70 2.465 20.01  1  0    3    1  Toyota Corona

If you would like to do it the other way round, namely excluding Toyota and Mazda cars, the filter command looks like this:

dplyr::filter(mtcars, !grepl('Toyota|Mazda', type))

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

Not sure why you need a Double in your map. In terms of what you're trying to do, you have an int[] and you just want counts of how many times each sequence occurs? Why would this required a Double anyway?

What I would do is to create a wrapper for the int array with a proper .equals and .hashCode methods to account for the fact that int[] object itself doesn't consider the data in it's version of these methods.

public class IntArrayWrapper {
    private int values[];

    public IntArrayWrapper(int[] values) {
        super();
        this.values = values;
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + Arrays.hashCode(values);
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        IntArrayWrapper other = (IntArrayWrapper) obj;
        if (!Arrays.equals(values, other.values))
            return false;
        return true;
    }

}

And then use google guava's multiset, which is meant exactly for the purpose of counting occurances, as long as the element type you put in it has proper .equals and .hashCode methods.

List<int[]> list = ...;
HashMultiset<IntArrayWrapper> multiset = HashMultiset.create();
for (int values[] : list) {
    multiset.add(new IntArrayWrapper(values));
}

Then, to get the count for any particular combination:

int cnt = multiset.count(new IntArrayWrapper(new int[] { 0, 1, 2, 3 }));

The essential idea here is to select the data you want to sum, and then sum them. This selection of data can be done in several different ways, a few of which are shown below.

Boolean indexing

Arguably the most common way to select the values is to use Boolean indexing.

With this method, you find out where column 'a' is equal to 1 and then sum the corresponding rows of column 'b'. You can use loc to handle the indexing of rows and columns:

>>> df.loc[df['a'] == 1, 'b'].sum()
15

The Boolean indexing can be extended to other columns. For example if df also contained a column 'c' and we wanted to sum the rows in 'b' where 'a' was 1 and 'c' was 2, we'd write:

df.loc[(df['a'] == 1) & (df['c'] == 2), 'b'].sum()

Query

Another way to select the data is to use query to filter the rows you're interested in, select column 'b' and then sum:

>>> df.query("a == 1")['b'].sum()
15

Again, the method can be extended to make more complicated selections of the data:

df.query("a == 1 and c == 2")['b'].sum()

Note this is a little more concise than the Boolean indexing approach.

Groupby

The alternative approach is to use groupby to split the DataFrame into parts according to the value in column 'a'. You can then sum each part and pull out the value that the 1s added up to:

>>> df.groupby('a')['b'].sum()[1]
15

This approach is likely to be slower than using Boolean indexing, but it is useful if you want check the sums for other values in column a:

>>> df.groupby('a')['b'].sum()
a
1    15
2     8

You may find an answer with this example : errorbar_demo_features.py

"""
Demo of errorbar function with different ways of specifying error bars.

Errors can be specified as a constant value (as shown in `errorbar_demo.py`),
or as demonstrated in this example, they can be specified by an N x 1 or 2 x N,
where N is the number of data points.

N x 1:
    Error varies for each point, but the error values are symmetric (i.e. the
    lower and upper values are equal).

2 x N:
    Error varies for each point, and the lower and upper limits (in that order)
    are different (asymmetric case)

In addition, this example demonstrates how to use log scale with errorbar.
"""
import numpy as np
import matplotlib.pyplot as plt

# example data
x = np.arange(0.1, 4, 0.5)
y = np.exp(-x)
# example error bar values that vary with x-position
error = 0.1 + 0.2 * x
# error bar values w/ different -/+ errors
lower_error = 0.4 * error
upper_error = error
asymmetric_error = [lower_error, upper_error]

fig, (ax0, ax1) = plt.subplots(nrows=2, sharex=True)
ax0.errorbar(x, y, yerr=error, fmt='-o')
ax0.set_title('variable, symmetric error')

ax1.errorbar(x, y, xerr=asymmetric_error, fmt='o')
ax1.set_title('variable, asymmetric error')
ax1.set_yscale('log')
plt.show()

Which plots this:

There are 8 bits in a byte (normally speaking in Windows).

However, if you are dealing with characters, it will depend on the charset/encoding. Unicode character can be 2 or 4 bytes, so that would be 16 or 32 bits, whereas Windows-1252 sometimes incorrectly called ANSI is only 1 bytes so 8 bits.

In Asian version of Windows and some others, the entire system runs in double-byte, so a character is 16 bits.

EDITED

Per Matteo's comment, all contemporary versions of Windows use 16-bits internally per character.

You can use concatenation operator and instead of declaring two variables only use one variable

String finalString =  cursor.getString(numcol) + cursor.getString(cursor.getColumnIndexOrThrow(db.KEY_DESTINATIE));

Like others have stated, you first need to have the CORS configuration in your S3 bucket:

<CORSConfiguration>
<CORSRule>
    <AllowedOrigin>*</AllowedOrigin>
    <AllowedMethod>GET</AllowedMethod>
    <AllowedMethod>HEAD</AllowedMethod> <!-- Add this -->
    <MaxAgeSeconds>3000</MaxAgeSeconds>
    <AllowedHeader>Authorization</AllowedHeader>
</CORSRule>
</CORSConfiguration>

But in my case after doing that, it was still not working. I was using Chrome (probably the same problem with other browsers).

The problem was that Chrome was caching the image with the headers (not containing the CORS data), so no matter what I tried to change in AWS, I would not see my CORS headers.

After clearing Chrome cache and reloading the page, the image had the expected CORS Headers

For Some Reason I could Not add Numbers(in string Format) to the DataGridView But This Worked For Me Hope it help someone!

//dataGridView1.Rows[RowCount].Cells[0].Value = FEString3;//This was not adding Stringed Numbers like "1","2","3"....
DataGridViewCell NewCell = new DataGridViewTextBoxCell();//Create New Cell
NewCell.Value = FEString3;//Set Cell Value
DataGridViewRow NewRow = new DataGridViewRow();//Create New Row
NewRow.Cells.Add(NewCell);//Add Cell to Row

PermGen stands for Permanent Generation.

Here is a brief blurb on DDJ

Visual Studio also has a feature that will generate a Property from a private variable.

If you right-click on a variable, in the context menu that pops up, click on the "Refactor" item, and then choose Encapsulate Field.... This will create a getter/setter property for a variable.

I'm not too big a fan of this technique as it is a little bit awkward to use if you have to create a lot of getters/setters, and it puts the property directly below the private field, which bugs me, because I usually have all of my private fields grouped together, and this Visual Studio feature breaks my class' formatting.

Here's a quick overview:

• Once references are gone, your object will likely be garbage collected.
• You can only count on statistical collection that keeps your heap size normal provided all references to garbage are really gone. In other words, there is no guarantee a specific object will ever be garbage collected.
  • It follows that your finalizer will also never be guaranteed to be called. Avoid finalizers.
• Two common sources of leaks:
  • Event handlers and delegates are references. If you subscribe to an event of an object, you are referencing to it. If you have a delegate to an object's method, you are referencing it.
  • Unmanaged resources, by definition, are not automatically collected. This is what the IDisposable pattern is for.
• Finally, if you want a reference that does not prevent the object from getting collected, look into WeakReference.

One last thing: If you declare Foo foo; without assigning it you don't have to worry - nothing is leaked. If Foo is a reference type, nothing was created. If Foo is a value type, it is allocated on the stack and thus will automatically be cleaned up.

Php will evaluate what you wrote between the [] brackets.

$foo = array('eins', 'zwei', 'apples', 'oranges');
var_dump($foo[3-1]);

Will produce string(6) "apples", because it returns $foo[2].

If you want that as a string, put inverted commas around it.

There are several ways to do this, shown below.

As a friendly warning, be careful and up-front to the user when dealing with account, profile, and contact data. If you misuse a user's email address or other personal information, bad things can happen.

Method A: Use AccountManager (API level 5+)

You can use AccountManager.getAccounts or AccountManager.getAccountsByType to get a list of all account names on the device. Fortunately, for certain account types (including com.google), the account names are email addresses. Example snippet below.

Pattern emailPattern = Patterns.EMAIL_ADDRESS; // API level 8+
Account[] accounts = AccountManager.get(context).getAccounts();
for (Account account : accounts) {
    if (emailPattern.matcher(account.name).matches()) {
        String possibleEmail = account.name;
        ...
    }
}

Note that this requires the GET_ACCOUNTS permission:

<uses-permission android:name="android.permission.GET_ACCOUNTS" />

More on using AccountManager can be found at the Contact Manager sample code in the SDK.

Method B: Use ContactsContract.Profile (API level 14+)

As of Android 4.0 (Ice Cream Sandwich), you can get the user's email addresses by accessing their profile. Accessing the user profile is a bit heavyweight as it requires two permissions (more on that below), but email addresses are fairly sensitive pieces of data, so this is the price of admission.

Below is a full example that uses a CursorLoader to retrieve profile data rows containing email addresses.

public class ExampleActivity extends Activity implements LoaderManager.LoaderCallbacks<Cursor> {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getLoaderManager().initLoader(0, null, this);
    }

    @Override
    public Loader<Cursor> onCreateLoader(int id, Bundle arguments) {
        return new CursorLoader(this,
                // Retrieve data rows for the device user's 'profile' contact.
                Uri.withAppendedPath(
                        ContactsContract.Profile.CONTENT_URI,
                        ContactsContract.Contacts.Data.CONTENT_DIRECTORY),
                ProfileQuery.PROJECTION,

                // Select only email addresses.
                ContactsContract.Contacts.Data.MIMETYPE + " = ?",
                new String[]{ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE},

                // Show primary email addresses first. Note that there won't be
                // a primary email address if the user hasn't specified one.
                ContactsContract.Contacts.Data.IS_PRIMARY + " DESC");
    }

    @Override
    public void onLoadFinished(Loader<Cursor> cursorLoader, Cursor cursor) {
        List<String> emails = new ArrayList<String>();
        cursor.moveToFirst();
        while (!cursor.isAfterLast()) {
            emails.add(cursor.getString(ProfileQuery.ADDRESS));
            // Potentially filter on ProfileQuery.IS_PRIMARY
            cursor.moveToNext();
        }

        ...
    }

    @Override
    public void onLoaderReset(Loader<Cursor> cursorLoader) {
    }

    private interface ProfileQuery {
        String[] PROJECTION = {
                ContactsContract.CommonDataKinds.Email.ADDRESS,
                ContactsContract.CommonDataKinds.Email.IS_PRIMARY,
        };

        int ADDRESS = 0;
        int IS_PRIMARY = 1;
    }
}

This requires both the READ_PROFILE and READ_CONTACTS permissions:

<uses-permission android:name="android.permission.READ_PROFILE" />
<uses-permission android:name="android.permission.READ_CONTACTS" />

Please find below example using Selenium "until.stalenessOf" and Jasmine assertion. It returns true when element is no longer attached to the DOM.

const { Builder, By, Key, until } = require('selenium-webdriver');

it('should not find element', async () => {
   const waitTime = 10000;
   const el = await driver.wait( until.elementLocated(By.css('#my-id')), waitTime);
   const isRemoved = await driver.wait(until.stalenessOf(el), waitTime);

   expect(isRemoved).toBe(true);
});

For ref.: Selenium:Until Doc

I'll try to explain what has already been said in a simpler way.

Whenever a shared lib is loaded, the loader (the code on the OS which load any program you run) changes some addresses in the code depending on where the object was loaded to.

In the above example, the "111" in the non-PIC code is written by the loader the first time it was loaded.

For not shared objects, you may want it to be like that because the compiler can make some optimizations on that code.

For shared object, if another process will want to "link" to that code he must read it to the same virtual addresses or the "111" will make no sense. but that virtual-space may already be in use in the second process.

1. This is a vast subject. Do not underestimate this point. And do not underestimate my point to not underestimate it.
2. I hear the Dragon Book is a (the?) place to start, along with searching. :) Get better at searching, eventually it will be your life.
3. Building your own programming language is absolutely a good exercise! But know that it will never be used for any practical purpose in the end. Exceptions to this are few and very far between.

So you can do it like this, but the limitation with the Parcelables is that the payload between activities has to be less than 1MB total. It's usually better to save the Bitmap to a file and pass the URI to the image to the next activity.

 protected void onCreate(Bundle savedInstanceState) {     setContentView(R.layout.my_layout);     Bitmap bitmap = getIntent().getParcelableExtra("image");     ImageView imageView = (ImageView) findViewById(R.id.imageview);     imageView.setImageBitmap(bitmap);  } 

You need to use JNI.

First of all use create a .dll using visual studio, that call system("cls"). After that use JNI to use this DDL.

I found this article that is nice:

http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=5170&lngWId=2

Using split function also you can get the first word from string.

<?php
$myvalue ="Test me more";
$result=split(" ",$myvalue);
echo $result[0];
?>

Three Possible Solutions

I know I'm coming late to the party, I've been looking if there were any new solutions to the variable configuration settings problem. There are a few answers that touch the solutions I have used in the past but most seem a bit convoluted. I thought I'd look at my old solutions and put the implementations together so that it might help people that are struggling with the same problem.

For this example I have used the following app setting in a console application:

<appSettings>
    <add key="EnvironmentVariableExample" value="%BaseDir%\bin"/>
    <add key="StaticClassExample" value="bin"/>
    <add key="InterpollationExample" value="{0}bin"/>
  </appSettings>

1. Use environment variables

I believe autocro autocro's answer touched on it. I'm just doing an implementation that should suffice when building or debugging without having to close visual studio. I have used this solution back in the day...

• Create a pre-build event that will use the MSBuild variables

  Warning: Use a variable that will not be replaced easily so use your project name or something similar as a variable name.

  SETX BaseDir "$(ProjectDir)"

• Reset variables; using something like the following:

  Refresh Environment Variables on Stack Overflow

• Use the setting in your code:

'

private void Test_Environment_Variables()
{
    string BaseDir = ConfigurationManager.AppSettings["EnvironmentVariableExample"];
    string ExpandedPath = Environment.ExpandEnvironmentVariables(BaseDir).Replace("\"", ""); //The function addes a " at the end of the variable
    Console.WriteLine($"From within the C# Console Application {ExpandedPath}");
}

'

2. Use string interpolation:

• Use the string.Format() function

`

private void Test_Interpollation()
{
    string ConfigPath = ConfigurationManager.AppSettings["InterpollationExample"];
    string SolutionPath = Path.GetFullPath(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, @"..\..\"));
    string ExpandedPath = string.Format(ConfigPath, SolutionPath.ToString());
    Console.WriteLine($"Using old interpollation {ExpandedPath}");
}

`

3. Using a static class, This is the solution I mostly use.

• The implementation

`

private void Test_Static_Class()
{
    Console.WriteLine($"Using a static config class {Configuration.BinPath}");
}

`

• The static class

`

static class Configuration
{
    public static string BinPath
    {
        get
        {
            string ConfigPath = ConfigurationManager.AppSettings["StaticClassExample"];
            string SolutionPath = Path.GetFullPath(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, @"..\..\"));
            return SolutionPath + ConfigPath;
        }
    }
}

`

Project Code:

App.config:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>
  <appSettings>
    <add key="EnvironmentVariableExample" value="%BaseDir%\bin"/>
    <add key="StaticClassExample" value="bin"/>
    <add key="InterpollationExample" value="{0}bin"/>
  </appSettings>
</configuration>

Program.cs

using System;
using System.Configuration;
using System.IO;

namespace ConfigInterpollation
{
    class Program
    {
        static void Main(string[] args)
        {
            new Console_Tests().Run_Tests();
            Console.WriteLine("Press enter to exit");
            Console.ReadLine();
        }        
    }

    internal class Console_Tests
    {
        public void Run_Tests()
        {
            Test_Environment_Variables();
            Test_Interpollation();
            Test_Static_Class();
        }
        private void Test_Environment_Variables()
        {
            string ConfigPath = ConfigurationManager.AppSettings["EnvironmentVariableExample"];
            string ExpandedPath = Environment.ExpandEnvironmentVariables(ConfigPath).Replace("\"", "");
            Console.WriteLine($"Using environment variables {ExpandedPath}");
        }

        private void Test_Interpollation()
        {
            string ConfigPath = ConfigurationManager.AppSettings["InterpollationExample"];
            string SolutionPath = Path.GetFullPath(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, @"..\..\"));
            string ExpandedPath = string.Format(ConfigPath, SolutionPath.ToString());
            Console.WriteLine($"Using interpollation {ExpandedPath}");
        }

        private void Test_Static_Class()
        {
            Console.WriteLine($"Using a static config class {Configuration.BinPath}");
        }
    }

    static class Configuration
    {
        public static string BinPath
        {
            get
            {
                string ConfigPath = ConfigurationManager.AppSettings["StaticClassExample"];
                string SolutionPath = Path.GetFullPath(Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, @"..\..\"));
                return SolutionPath + ConfigPath;
            }
        }
    }
}

Pre-build event:

Project Settings -> Build Events

Note that in Internet Explorer there are issues with dynamically created forms. A form created like this will not submit in IE (9):

var form = $('<form method="post" action="/test/Delete/">' +
             '<input type="hidden" name="id" value="' + myid + '"></form>');
$(form).submit();

To get it working in IE create the form element and attach it before submitting like so:

var form = document.createElement("form");
$(form).attr("action", "/test/Delete")
       .attr("method", "post");
$(form).html('<input type="hidden" name="id" value="' + myid + '" />');
document.body.appendChild(form);
$(form).submit();
document.body.removeChild(form);

Creating the form like in example 1 and then attaching it will not work - in IE9 it throws a JScript error DOM Exception: HIERARCHY_REQUEST_ERR (3)

Props to Tommy W @ https://stackoverflow.com/a/6694054/694325

This exception because of when you call session.getEntityById(), the session will be closed. So you need to re-attach the entity to the session. Or Easy solution is just configure default-lazy="false" to your entity.hbm.xml or if you are using annotations just add @Proxy(lazy=false) to your entity class.

These need to go as different commands e.g.:

NAME=sam; echo "$NAME"
NAME=sam && echo "$NAME"

The expansion $NAME to empty string is done by the shell earlier, before running echo, so at the time the NAME variable is passed to the echo command's environment, the expansion is already done (to null string).

To get the same result in one command:

NAME=sam printenv NAME

Append a semicolon to the following line to fix the issue.

font-family:    Arial, Helvetica, sans-serif;

This function checks for other types of whitespace, not just space (tab, carriage return, etc.)

import some from 'lodash/fp/some'
const whitespaceCharacters = [' ', '  ',
  '\b', '\t', '\n', '\v', '\f', '\r', `\"`, `\'`, `\\`,
  '\u0008', '\u0009', '\u000A', '\u000B', '\u000C',
'\u000D', '\u0020','\u0022', '\u0027', '\u005C',
'\u00A0', '\u2028', '\u2029', '\uFEFF']
const hasWhitespace = char => some(
  w => char.indexOf(w) > -1,
  whitespaceCharacters
)

console.log(hasWhitespace('a')); // a, false
console.log(hasWhitespace(' ')); // space, true
console.log(hasWhitespace(' ')); // tab, true
console.log(hasWhitespace('\r')); // carriage return, true

If you don't want to use Lodash, then here is a simple some implementation with 2 s:

const ssome = (predicate, list) =>
{
  const len = list.length;
  for(const i = 0; i<len; i++)
  {
    if(predicate(list[i]) === true) {
      return true;
    }
  }
  return false;
};

Then just replace some with ssome.

const hasWhitespace = char => some(
  w => char.indexOf(w) > -1,
  whitespaceCharacters
)

For those in Node, use:

const { some } = require('lodash/fp');

You can now (C++14) return a locally-defined (i.e. defined inside the function) as follows:

auto f()
{
    struct S
    {
      int a;
      double b;
    } s;
    s.a = 42;
    s.b = 42.0;
    return s;
}

auto x = f();
a = x.a;
b = x.b;

Check as @joyfun did for the correct version of jackson but also check our headers ... Accept / may not be transmitted by the client ... use firebug or equivalent to check what your get request is actually sending. I think the headers attribute of the annotation /may/ be checking literals although I'm not 100% sure.

Here is how I do it and works both for create and edit:

//How to do it with enums
<div class="editor-field">
   @Html.RadioButtonFor(x => x.gender, (int)Gender.Male) Male
   @Html.RadioButtonFor(x => x.gender, (int)Gender.Female) Female
</div>

//And with Booleans
<div class="editor-field">
   @Html.RadioButtonFor(x => x.IsMale, true) Male
   @Html.RadioButtonFor(x => x.IsMale, false) Female
</div>

the provided values (true and false) are the values that the engine will render as the values for the html element i.e.:

<input id="IsMale" type="radio" name="IsMale" value="True">
<input id="IsMale" type="radio" name="IsMale" value="False">

And the checked property is dependent on the Model.IsMale value.

Razor engine seems to internally match the set radio button value to your model value, if a proper from and to string convert exists for it. So there is no need to add it as an html attribute in the helper method.

For this type error: UnexpectedTypeException ERROR: We are trying to use incorrect Hibernate validator annotation on any bean property. For this same issue for my Springboot project( validating type 'java.lang.Integer')

The solution that worked for me is using @NotNull for Integer.

Concat returns a new sequence without modifying the original list. Try myList1.AddRange(myList2).

01. Integer can be null. But int cannot be null.

Integer value1 = null; //OK

int value2 = null      //Error

02. Only can pass Wrapper Classes type values to any collection class.

(Wrapper Classes - Boolean,Character,Byte,Short,Integer,Long,Float,Double)

List<Integer> element = new ArrayList<>();
int valueInt = 10;
Integer  valueInteger = new Integer(value);
element.add(valueInteger);

But normally we add primitive values to collection class? Is point 02 correct?

List<Integer> element = new ArrayList<>();
element.add(5);

Yes 02 is correct, beacouse autoboxing.

Autoboxing is the automatic conversion that the java compiler makes between the primitive type and their corresponding wrapper class.

Then 5 convert as Integer value by autoboxing.

Please check "top" command then if your script or any are running please note 'PID'

PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND

kill <you process ID>

Example : kill 1384

if you are a sudo user i mean if you got sudo access:

      sudo sh startup.sh 

otherwise: sh startup.sh

But things is that you have to be on the bin directory of your server like

cd /home/nanofaroque/servers/apache-tomcat-7.0.47/bin

To some degree this is possible, you can create an alias to a variable using closures:

Function.prototype.toString = function() {
    return this();
}

var x = 1;
var y = function() { return x }
x++;
alert(y); // prints 2, no need for () because of toString redefinition 

assuming your using click events, just unbind that one.

example

if (current = 1){ 
    $('li:eq(2)').unbind("click");
}

EDIT: Are you currently binding a click event to your list somewhere? Based on your comment above, I'm wondering if this is really what you're doing? How are you enabling the click? Is it just an anchor(<a> tag) ? A little more explicit information will help us answer your question.

UPDATE:

Did some playing around with the :eq() operator. http://jsfiddle.net/ehudokai/VRGfS/5/

As I should have expected it is a 0 based index operator. So if you want to turn of the second element in your selection, where your selection is

$("#navigation a")

you would simply add :eq(1) (the second index) and then .unbind("click") So:

if(current == 1){
    $("#navigation a:eq(1)").unbind("click");
}

Ought to do the trick.

Hope this helps!

If you are using an <a/> to trigger the report, you can try this approach. Instead of attempting to spawn a new window when window.open() fails, make the default scenario to open a new window via target (and prevent it if window.open() succeeds).

HTML

<a href="http://my/url" target="_blank" id="myLink">Link</a>

JS

var spawn = function (e) {
    try {
        window.open(this.href, "","width=1002,height=700,location=0,menubar=0,scrollbars=1,status=1,resizable=0")
        e.preventDefault(); // Or: return false;
    } catch(e) {
    // Allow the default event handler to take place
    }
}

document.getElementById("myLink").onclick = spawn;

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

check your branch on your repo. maybe someone delete it.

I am running Python 3.6 on MacOS Catalina. My issue was that I tried to install mysqlclient==1.4.2.post1 and it keeps throwing mysql_config not found error.

This is the steps I took to solve the issue.

1. Install mysql-connector-c using brew (if you have mysql already install unlink first brew unlink mysql) - brew install mysql-connector-c
2. Open mysql_config and edit the file around line 112

# Create options 
libs="-L$pkglibdir"
libs="$libs -lmysqlclient -lssl -lcrypto"

3. brew info openssl - this will give you more information on what needs to be done about putting openssl in PATH
4. in relation to step 3, you need to do this to put openssl in PATH - echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile
5. for compilers to find openssl - export LDFLAGS="-L/usr/local/opt/openssl/lib"
6. for compilers to find openssl - export CPPFLAGS="-I/usr/local/opt/openssl/include"

Correct me if wrong...I think request does persist between consecutive pages..

Think you traverse from page 1--> page 2-->page 3.

You have some value set in the request object using setAttribute from page 1, which you retrieve in page 2 using getAttribute,then if you try setting something again in same request object to retrieve it in page 3 then it fails giving you null value as "the request that created the JSP, and the request that gets generated when the JSP is submitted are completely different requests and any attributes placed on the first one will not be available on the second".

I mean something like this in page 2 fails:

Where as the same thing has worked in case of page 1 like:

So I think I would need to proceed with either of the two options suggested by Phill.

You could use jQuery

Other languages have short cuts for ranges of field numbers, but not awk, you'll have to write your code as your fear ;-)

awk -F, 'BEGIN {OFS=","} { print $1, $2, $3, $4 ..... $30, $33}' infile.csv > outfile.csv

There is no direct function in awk to use field names as column specifiers.

I hope this helps.

Use:

awk -v FS='\t' -v OFS='\t' ...

Example from one of my scripts.

I use the FS and OFS variables to manipulate BIND zone files, which are tab delimited:

awk -v FS='\t' -v OFS='\t' \
    -v record_type=$record_type \
    -v hostname=$hostname \
    -v ip_address=$ip_address '
$1==hostname && $3==record_type {$4=ip_address}
{print}
' $zone_file > $temp

This is a clean and easy to read way to do this.

If you want to set text at design time in xml file just simple android:text="username" add this property.

<EditText
    android:id="@+id/edtUsername"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="username"/>

If you want to set text programmatically in Java

EditText edtUsername = findViewById(R.id.edtUsername);
edtUsername.setText("username");

and in kotlin same like java using getter/setter

edtUsername.setText("username")

But if you want to use .text from principle then

edtUsername.text = Editable.Factory.getInstance().newEditable("username")

because of EditText.text requires an editable at firstplace not String

Restarting the SQL Server will clear up the log space used by your database. If this however is not an option, you can try the following:

* Issue a CHECKPOINT command to free up log space in the log file.

* Check the available log space with DBCC SQLPERF('logspace'). If only a small 
  percentage of your log file is actually been used, you can try a DBCC SHRINKFILE 
  command. This can however possibly introduce corruption in your database. 

* If you have another drive with space available you can try to add a file there in 
  order to get enough space to attempt to resolve the issue.

Hope this will help you in finding your solution.

like some say boost::replace_all

here a dummy example:

    #include <boost/algorithm/string/replace.hpp>

    std::string path("file.gz");
    boost::replace_all(path, ".gz", ".zip");

Just a note: You might have set up your service differently using the forms interface to add a service installer and project installer. In that case replace where it says serviceInstaller.ServiceName with "name from designer".ServiceName.

You also don't need the private members in this case.

Thanks for the help.

For directories dirname gets tripped for ../ and returns ./.

nolan6000's function can be modified to fix that:

get_abs_filename() {
  # $1 : relative filename
  if [ -d "${1%/*}" ]; then
    echo "$(cd ${1%/*}; pwd)/${1##*/}"
  fi
}

What about using the following:

int number = input.nextInt();
if (number < 0) {
    // negative
} else {
   // it's a positive
}

You can write following codes to achieve this task:

SELECT ... FROM ... WHERE ... 
INTO OUTFILE 'textfile.csv'
FIELDS TERMINATED BY '|'

It export the result to CSV and then export it to excel sheet.

Do the following :

"CREATE APPLICATION" having the same name which you want to upload before.
Click create.
After creation of the app now click on the "App releases"
Click on the "MANAGE PRODUCTION"
Click on the "CREATE RELEASE"
Here you see "Google Play App Signing" dialog.
Just click on the "OPT-OUT" button.
It will ask you to confirm it. Just click on the "confirm" button

I'm not using JAX-RS, but I've got a similar scenario where I use:

response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());

As Davide Gualano has been told. This one

$("#myDiv").load("myScript.php?var=x&var2=y&var3=z")

use GET method for sending the request, and this one

$("#myDiv").load("myScript.php", {var:x, var2:y, var3:z})

use POST method for sending the request. But any limitation that is applied to each method (post/get) is applied to the alternative usages that has been mentioned in the question.

For example: url length limits the amount of sending data in GET method.

You should return the line that redirects

return res.redirect('/UserHomePage');

This worked for me in Swift 5.0. Set the Storyboard Id in the identity inspector as "destinationVC".

@IBAction func buttonTapped(_ sender: Any) {
    let storyboard: UIStoryboard = UIStoryboard(name: "Main", bundle: Bundle.main)
    let destVC = storyboard.instantiateViewController(withIdentifier: "destinationVC") as! MyViewController

    destVC.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
    destVC.modalTransitionStyle = UIModalTransitionStyle.crossDissolve

    self.present(destVC, animated: true, completion: nil)
}

The examples contained in this blog post do the trick.

There are different regex engines but I think most of them will work with this:

            if (checked) {
                alert('checked');
            } else {
                alert('unchecked');
            }
        });
    });

You can use Oracle.ManagedDataAccess.dll instead (download from Oracle), include that dll in you project bin dir, add reference to that dll in the project. In code, "using Oracle.MangedDataAccess.Client". Deploy project to server as usual. No need install Oracle Client on server. No need to add assembly info in web.config.

Deleting Elements in an Array if Element is a Certain value VBA

to delete elements in an Array wih certain condition, you can code like this

For i = LBound(ArrValue, 2) To UBound(ArrValue, 2)
    If [Certain condition] Then
        ArrValue(1, i) = "-----------------------"
    End If
Next i

StrTransfer = Replace(Replace(Replace(join(Application.Index(ArrValue(), 1, 0), ","), ",-----------------------,", ",", , , vbBinaryCompare), "-----------------------,", "", , , vbBinaryCompare), ",-----------------------", "", , , vbBinaryCompare)
ResultArray = join( Strtransfer, ",")

I often manipulate 1D-Array with Join/Split but if you have to delete certain value in Multi Dimension I suggest you to change those Array into 1D-Array like this

strTransfer = Replace(Replace(Replace(Replace(Names.Add("A", MultiDimensionArray), Chr(34), ""), "={", ""), "}", ""), ";", ",")
'somecode to edit Array like 1st code on top of this comment
'then loop through this strTransfer to get right value in right dimension
'with split function.

One way to partially get around the problem is to use the API Level suffix. I use res/layout-v1, res/layout-v2 etc to hold multiple sub projects in the same apk. This mechanism can be used for all resource types.

Obviously, this can only be used if you are targeting API levels above the res/layout-v? you are using.

Also, watch out for the bug in Android 1.5 and 1.6. See Andoroid documentation about the API Level suffix.

The reason I like Rcpp so much is that I don't always get how R Core thinks, and with Rcpp, more often than not, I don't have to.

Speaking philosophically, you're in a state of sin with regards to the functional paradigm, which tries to ensure that every value appears independent of every other value; changing one value should never cause a visible change in another value, the way you get with pointers sharing representation in C.

The problems arise when functional programming signals the small craft to move out of the way, and the small craft replies "I'm a lighthouse". Making a long series of small changes to a large object which you want to process on in the meantime puts you square into lighthouse territory.

In the C++ STL, push_back() is a way of life. It doesn't try to be functional, but it does try to accommodate common programming idioms efficiently.

With some cleverness behind the scenes, you can sometimes arrange to have one foot in each world. Snapshot based file systems are a good example (which evolved from concepts such as union mounts, which also ply both sides).

If R Core wanted to do this, underlying vector storage could function like a union mount. One reference to the vector storage might be valid for subscripts 1:N, while another reference to the same storage is valid for subscripts 1:(N+1). There could be reserved storage not yet validly referenced by anything but convenient for a quick push_back(). You don't violate the functional concept when appending outside the range that any existing reference considers valid.

Eventually appending rows incrementally, you run out of reserved storage. You'll need to create new copies of everything, with the storage multiplied by some increment. The STL implementations I've use tend to multiply storage by 2 when extending allocation. I thought I read in R Internals that there is a memory structure where the storage increments by 20%. Either way, growth operations occur with logarithmic frequency relative to the total number of elements appended. On an amortized basis, this is usually acceptable.

As tricks behind the scenes go, I've seen worse. Every time you push_back() a new row onto the dataframe, a top level index structure would need to be copied. The new row could append onto shared representation without impacting any old functional values. I don't even think it would complicate the garbage collector much; since I'm not proposing push_front() all references are prefix references to the front of the allocated vector storage.

This could also be the case if you have created a systemd service that has:

[Service]
Restart=always
ExecStart=/usr/bin/docker container start -a my_container
ExecStop=/usr/bin/docker container stop -t 2 my_container

document.getElementById('loginSubmit').submit();

or, use the same code as the onclick handler:

changeAction('submitInput','loginForm');
document.forms['loginForm'].submit();

(Though that onclick handler is kind of stupidly-written: document.forms['loginForm'] could be replaced with this.)

std::string str(buffer, buffer + length);

Or, if the string already exists:

str.assign(buffer, buffer + length);

Edit: I'm still not completely sure I understand the question. But if it's something like what JoshG is suggesting, that you want up to length characters, or until a null terminator, whichever comes first, then you can use this:

std::string str(buffer, std::find(buffer, buffer + length, '\0'));

The apparent contradictions that appear in the question are caused because in one case the Equals function is called on a string object, and in the other case the == operator is called on the System.Object type. string and object implement equality differently from each other (value vs. reference respectively).

Beyond this fact, any type can define == and Equals differently, so in general they are not interchangeable.

Here’s an example using double (from Joseph Albahari’s note to §7.9.2 of the C# language specification):

double x = double.NaN;
Console.WriteLine (x == x);         // False
Console.WriteLine (x != x);         // True
Console.WriteLine (x.Equals(x));    // True

He goes on to say that the double.Equals(double) method was designed to work correctly with lists and dictionaries. The == operator, on the other hand, was designed to follow the IEEE 754 standard for floating point types.

In the specific case of determining string equality, the industry preference is to use neither == nor string.Equals(string) most of the time. These methods determine whether two string are the same character-for-character, which is rarely the correct behavior. It is better to use string.Equals(string, StringComparison), which allows you to specify a particular type of comparison. By using the correct comparison, you can avoid a lot of potential (very hard to diagnose) bugs.

Here’s one example:

string one = "Caf\u00e9";        // U+00E9 LATIN SMALL LETTER E WITH ACUTE
string two = "Cafe\u0301";       // U+0301 COMBINING ACUTE ACCENT
Console.WriteLine(one == two);                                          // False
Console.WriteLine(one.Equals(two));                                     // False
Console.WriteLine(one.Equals(two, StringComparison.InvariantCulture));  // True

Both strings in this example look the same ("Café"), so this could be very tough to debug if using a naïve (ordinal) equality.

I got this error fatal error lnk1104: cannot open file 'kernel32.lib'. this error is getting because there is no path in VC++ directories. To solve this problem

Open Visual Studio 2008

1. go to Tools-options-Projects and Solutions-VC++ directories-*
2. then at right corner select Library files
3. here you need to add path of kernel132.lib

In my case It is C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib

end(preg_split("#(\\\\|\\/)#", Class_Name::class))

Class_Name::class: return the class with the namespace. So after you only need to create an array, then get the last value of the array.

PSR-5: PHPDoc proposes a form of Generics-style notation.

Syntax

Type[]
Type<Type>
Type<Type[, Type]...>
Type<Type[|Type]...>

Values in a Collection MAY even be another array and even another Collection.

Type<Type<Type>>
Type<Type<Type[, Type]...>>
Type<Type<Type[|Type]...>>

Examples

<?php

$x = [new Name()];
/* @var $x Name[] */

$y = new Collection([new Name()]);
/* @var $y Collection<Name> */

$a = new Collection(); 
$a[] = new Model_User(); 
$a->resetChanges(); 
$a[0]->name = "George"; 
$a->echoChanges();
/* @var $a Collection<Model_User> */

Note: If you are expecting an IDE to do code assist then it's another question about if the IDE supports PHPDoc Generic-style collections notation.

From my answer to this question.

It says “Android library projects cannot be launched” because Android library projects cannot be launched. That simple. You cannot run a library. If you want to test a library, create an Android project that uses the library, and execute it.

Here's a rather unconventional way of doing it:

#inputcontainer
{
    display:table-cell; //display like a <td> to make the vertical-align work
    text-align:center; //centre the input horizontally
    vertical-align:middle; //centre the input vertically


    width:200px; //widen the div for demo purposes
    height:200px; //make the div taller for demo purposes
    background:green; //change the background of the div for demo purposes
}

It might not be the best way to do it, and margin? won't work, but it does the job. If you need to use margin, then you could wrap the div that displays as a table cell in another 'normal' div.

I have came up with an easy resolve using a simple form hidden on my website with the same information the users logged in with. Example: If you want a user to be logged in on this form, you can add something like this to the follow form below.

<input type="checkbox" name="autologin" id="autologin" />

As far I know I am the first to hide a form and submit it via clicking a link. There is the link submitting a hidden form with the information. It is not 100% safe if you don't like auto login methods on your website with passwords sitting on a hidden form password text area...

Okay, so here is the work. Let’s say $siteid is the account and $sitepw is password.

First make the form in your PHP script. If you don’t like HTML in it, use minimal data and then echo in the value in a hidden form. I just use a PHP value and echo in anywhere I want pref next to the form button as you can't see it.

PHP form to print

$hidden_forum = '
<form id="alt_forum_login" action="./forum/ucp.php?mode=login" method="post" style="display:none;">
    <input type="text" name="username" id="username" value="'.strtolower($siteid).'" title="Username" />
    <input type="password" name="password" id="password" value="'.$sitepw.'" title="Password" />
</form>';

PHP and link to submit form

<?php print $hidden_forum; ?>
<pre><a href="#forum" onClick="javascript: document.getElementById('alt_forum_login').submit();">Forum</a></pre>

To trigger a search every time the enter key is pressed, use this:

$(document).keypress(function(event) {
    var keycode = (event.keyCode ? event.keyCode : event.which);
    if (keycode == '13') {
        $('#btnSearch').click();
    }
}

I found this to be the biggest help:

Use HAProxy 1.5 or newer, and simply add the following line to the frontend config:

I tried this code to accept files using Ajax and on submit file gets store using my php file. Code modified slightly to work. (Uploaded Files: PDF,JPG)

function verify1() {
    jQuery.ajax({
        type: 'POST',
        url:"functions.php",
        data: new FormData($("#infoForm1")[0]),
        processData: false, 
        contentType: false, 
        success: function(returnval) {
             $("#show1").html(returnval);
             $('#show1').show();
         }
    });
}

Just print the file details and check. You will get Output. If error let me know.

/ and .. in the user provided file name can be harmful. So you should get rid of these by something like:

$fname = str_replace('..', '', $fname);
$fname = str_replace('/',  '', $fname);

Variables names are only locally meaningful.

Once you hit

return s1,s2,s3,s4

at the end of the method, Python constructs a tuple with the values of s1, s2, s3 and s4 as its four members at index 0, 1, 2 and 3 - NOT a dictionary of variable names to values, NOT an object with variable names and their values, etc.

If you want the variable names to be meaningful after you hit return in the method, you must create an object or dictionary.

Try this:

if (items.elementAt(1) instanceof Double) {
   sum.add( i, items.elementAt(1));
}

I think the easiest way to make it done is :

std::vector<std::vector<int>>v(10,std::vector<int>(11,100));

10 is the size of the outer or global vector, which is the main one, and 11 is the size of inner vector of type int, and initial values are initialized to 100! That's my first help on stack, i think it helps someone.

I found that starting the emulator with 'wipe user data' checked cleared this problem up for me after I rebuilt my dev machine from Vista x64 to Win7 x64.

subprocess.Popen takes a cwd argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'), or use r'd:\test\local' so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t part will be translated to a tab.

So, your new line should look like:

subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')

To use your Python script path as cwd, import os and define cwd using this:

os.path.dirname(os.path.realpath(__file__))

Proxy timeouts are well, for proxies, not for FastCGI...

The directives that affect FastCGI timeouts are client_header_timeout, client_body_timeout and send_timeout.

Edit: Considering what's found on nginx wiki, the send_timeout directive is responsible for setting general timeout of response (which was bit misleading). For FastCGI there's fastcgi_read_timeout which is affecting the fastcgi process response timeout.

HTH.

My case is the page is sending multiple requests with different parameters when it was open. So most are being "stalled". Following requests immediately sent gets "stalled". Avoiding unnecessary requests would be better (to be lazy...).

You can better understand what Looper is in the context of GUI framework. Looper is made to do 2 things.

1) Looper transforms a normal thread, which terminates when its run() method return, into something run continuously until Android app is running, which is needed in GUI framework (Technically, it still terminates when run() method return. But let me clarify what I mean in below).

2) Looper provides a queue where jobs to be done are enqueued, which is also needed in GUI framework.

As you may know, when an application is launched, the system creates a thread of execution for the application, called “main”, and Android applications normally run entirely on a single thread by default the “main thread”. But main thread is not some secret, special thread. It's just a normal thread similar to threads you create with new Thread() code, which means it terminates when its run() method return! Think of below example.

public class HelloRunnable implements Runnable {
    public void run() {
        System.out.println("Hello from a thread!");
    }

    public static void main(String args[]) {
        (new Thread(new HelloRunnable())).start();
    }
}

Now, let's apply this simple principle to Android apps. What would happen if an Android app runs on normal thread? A thread called "main" or "UI" or whatever starts your application, and draws all UI. So, the first screen is displayed to users. So what now? The main thread terminates? No, it shouldn’t. It should wait until users do something, right? But how can we achieve this behavior? Well, we can try with Object.wait() or Thread.sleep(). For example, main thread finishes its initial job to display first screen, and sleeps. It awakes, which means interrupted, when a new job to do is fetched. So far so good, but at this moment we need a queue-like data structure to hold multiple jobs. Think about a case when a user touches screen serially, and a task takes longer time to finish. So, we need to have a data structure to hold jobs to be done in first-in-first-out manner. Also, you may imagine, implementing ever-running-and-process-job-when-arrived thread using interrupt is not easy, and leads to complex and often unmaintainable code. We'd rather create a new mechanism for such purpose, and that is what Looper is all about. The official document of Looper class says, "Threads by default do not have a message loop associated with them", and Looper is a class "used to run a message loop for a thread". Now you can understand what it means.

To make things more clear, let's check the code where main thread is transformed. It all happens in ActivityThread class. In its main() method, you can find below code, which turns a normal main thread into something what we need.

public final class ActivityThread {
    ...
    public static void main(String[] args) {
        ...
        Looper.prepareMainLooper();
        Looper.loop();
        ...
    }
}

and Looper.loop() method loop infinitely and dequeue a message and process one at a time:

public static void loop() {
    ...
    for (;;) {
        Message msg = queue.next(); // might block
        if (msg == null) {
            // No message indicates that the message queue is quitting.
            return;
        }
        ...
        msg.target.dispatchMessage(msg);
        ...
    }
}

So, basically Looper is a class that is made to address a problem that occurs in GUI framework. But this kind of needs can also happen in other situation as well. Actually it is a pretty famous pattern for multi threads application, and you can learn more about it in "Concurrent Programming in Java" by Doug Lea(Especially, chapter 4.1.4 "Worker Threads" would be helpful). Also, you can imagine this kind of mechanism is not unique in Android framework, but all GUI framework may need somewhat similar to this. You can find almost same mechanism in Java Swing framework.

Basically this is what you need to do:
in the first activity:

Intent intent = new Intent();
intent.setAction(this, SecondActivity.class);
intent.putExtra(tag, value);
startActivity(intent);

and in the second activtiy:

Intent intent = getIntent();
intent.getBooleanExtra(tag, defaultValue);
intent.getStringExtra(tag, defaultValue);
intent.getIntegerExtra(tag, defaultValue);

one of the get-functions will give return you the value, depending on the datatype you are passing through.

It seems like you are essentially looking into computing the z-score or standard score of your data, which is calculated through the formula: z = (x-mean(x))/std(x)

This should work:

%% Original data (Normal with mean 1 and standard deviation 2)
x = 1 + 2*randn(100,1);
mean(x)
var(x)
std(x)

%% Normalized data with mean 0 and variance 1
z = (x-mean(x))/std(x);
mean(z)
var(z)
std(z)

By far the best tool I have used for reverse engineering, and round tripping java -> UML is Borland's Together. It is based on Eclipse (not just a single plugin) and really works well.

There is no built-in method, but there are several ways to do it. The most straightforward way that I can think of at the moment is:

1. Create a subclass of JComponent.
2. Override the paintComponent(Graphics g) method to paint the image that you want to display.
3. Set the content pane of the JFrame to be this subclass.

Some sample code:

class ImagePanel extends JComponent {
    private Image image;
    public ImagePanel(Image image) {
        this.image = image;
    }
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.drawImage(image, 0, 0, this);
    }
}

// elsewhere
BufferedImage myImage = ImageIO.read(...);
JFrame myJFrame = new JFrame("Image pane");
myJFrame.setContentPane(new ImagePanel(myImage));

Note that this code does not handle resizing the image to fit the JFrame, if that's what you wanted.

if( strpos( $url, $word ) !== false ) {
    // Do something
}

If you are still looking for one, I just released mine: http://github.com/weixiyen/jquery-filedrop

Works for Firefox 3.6 right now. I decided not to do the Chrome hack for now and let Webkit catch up with FileReader() in the next versions of Safari and Chrome.

This plugin is future compatible.

FileReader() is the official standard over something like XHR.getAsBinary() which is deprecated according to mozilla.

It's also the only HTML5 desktop drag+drop plugin out there that I know of which allows you to send extra data along with the file, including data that can be calculated at the time of upload with a callback function.

I wrote an article on this subject over here. I think it could help you.

Typically it's doing something like that:

static void Main(string[] args)
{
    // Convert from a DataTable source to an IEnumerable.
    var usersSourceDataTable = CreateMockUserDataTable();
    var usersConvertedList = usersSourceDataTable.ToEnumerable<User>();

    // Convert from an IEnumerable source to a DataTable.
    var usersSourceList = CreateMockUserList();
    var usersConvertedDataTable = usersSourceList.ToDataTable<User>();
}

If you're using Ubuntu, you can put a shell script in one of these folders: /etc/cron.daily, /etc/cron.hourly, /etc/cron.monthly or /etc/cron.weekly.

For more detail, check out this post: https://askubuntu.com/questions/2368/how-do-i-set-up-a-cron-job

it's not that complicated.

please try this:

$(document).ready(function(){
    var modalId = "#myModal";
    resize: function(){
            var new_margin = Math.ceil(($(window).height() - $(modalId).find('.modal-dialog').height()) / 2);
            $(modalId).find('.modal-dialog').css('margin-top', new_margin + 'px');
    }
    $(window).resize(function(){
        resize();
    });
    $(modalId).on('shown.bs.modal', function(){
        resize();
    });
});

int space = 40;
printf("%*s", space, "Hello");

This statement will reserve a row of 40 characters, print string at the end of the row (removing extra spaces such that the total row length is constant at 40). Same can be used for characters and integers as follows:

printf("%*d", space, 10);
printf("%*c", space, 'x');

This method using a parameter to determine spaces is useful where a variable number of spaces is required. These statements will still work with integer literals as follows:

printf("%*d", 10, 10);
printf("%*c", 20, 'x');
printf("%*s", 30, "Hello");

Hope this helps someone like me in future.

The two int variables are defined in the header file. This means that every source file which includes the header will contain their definition (header inclusion is purely textual). The of course leads to multiple definition errors.

You have several options to fix this.

1. Make the variables static (static int WIDTH = 1024;). They will still exist in each source file, but their definitions will not be visible outside of the source file.

2. Turn their definitions into declarations by using extern (extern int WIDTH;) and put the definition into one source file: int WIDTH = 1024;.

3. Probably the best option: make the variables const (const int WIDTH = 1024;). This makes them static implicitly, and also allows them to be used as compile-time constants, allowing the compiler to use their value directly instead of issuing code to read it from the variable etc.

You could include count(id). That will always return.

select count(field1), field1 from table where id = 123 limit 1;

If the answer of Kapil Vats is not working try something like this:

drawable/divider_horizontal_green_22.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <size android:width="22dip"/>
    <solid android:color="#00ff00"/>

</shape>

layout/your_layout.xml

LinearLayout 
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:id="@+id/llTopBar"
            android:orientation="horizontal"
            android:divider="@drawable/divider_horizontal_green_22"
            android:showDividers="middle"
           >

I encountered an issue where the padding attribute wasn't working, thus I had to set the height of the divider directly in the divider.

Note:

If you want to use it in vertical LinearLayout, make a new one, like this: drawable/divider_vertical_green_22.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <size android:height="22dip"/>
    <solid android:color="#00ff00"/>

</shape>

Just call css with one argument

  $('#idDetails').css('display');

If I understand your question. Otherwise, you want cletus' answer.

You can use jsdom

const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const { document } = (new JSDOM(`...`)).window;

or, take a look at cheerio, it may more suitable in your case.

I had the requirement to retrieve all properties whose key starts with a distinct prefix (e.g. all properties starting with "log4j.appender.") and wrote following Code (using streams and lamdas of Java 8).

public static Map<String,Object> getPropertiesStartingWith( ConfigurableEnvironment aEnv,
                                                            String aKeyPrefix )
{
    Map<String,Object> result = new HashMap<>();

    Map<String,Object> map = getAllProperties( aEnv );

    for (Entry<String, Object> entry : map.entrySet())
    {
        String key = entry.getKey();

        if ( key.startsWith( aKeyPrefix ) )
        {
            result.put( key, entry.getValue() );
        }
    }

    return result;
}

public static Map<String,Object> getAllProperties( ConfigurableEnvironment aEnv )
{
    Map<String,Object> result = new HashMap<>();
    aEnv.getPropertySources().forEach( ps -> addAll( result, getAllProperties( ps ) ) );
    return result;
}

public static Map<String,Object> getAllProperties( PropertySource<?> aPropSource )
{
    Map<String,Object> result = new HashMap<>();

    if ( aPropSource instanceof CompositePropertySource)
    {
        CompositePropertySource cps = (CompositePropertySource) aPropSource;
        cps.getPropertySources().forEach( ps -> addAll( result, getAllProperties( ps ) ) );
        return result;
    }

    if ( aPropSource instanceof EnumerablePropertySource<?> )
    {
        EnumerablePropertySource<?> ps = (EnumerablePropertySource<?>) aPropSource;
        Arrays.asList( ps.getPropertyNames() ).forEach( key -> result.put( key, ps.getProperty( key ) ) );
        return result;
    }

    // note: Most descendants of PropertySource are EnumerablePropertySource. There are some
    // few others like JndiPropertySource or StubPropertySource
    myLog.debug( "Given PropertySource is instanceof " + aPropSource.getClass().getName()
                 + " and cannot be iterated" );

    return result;

}

private static void addAll( Map<String, Object> aBase, Map<String, Object> aToBeAdded )
{
    for (Entry<String, Object> entry : aToBeAdded.entrySet())
    {
        if ( aBase.containsKey( entry.getKey() ) )
        {
            continue;
        }

        aBase.put( entry.getKey(), entry.getValue() );
    }
}

Note that the starting point is the ConfigurableEnvironment which is able to return the embedded PropertySources (the ConfigurableEnvironment is a direct descendant of Environment). You can autowire it by:

@Autowired
private ConfigurableEnvironment  myEnv;

If you not using very special kinds of property sources (like JndiPropertySource, which is usually not used in spring autoconfiguration) you can retrieve all properties held in the environment.

The implementation relies on the iteration order which spring itself provides and takes the first found property, all later found properties with the same name are discarded. This should ensure the same behaviour as if the environment were asked directly for a property (returning the first found one).

Note also that the returned properties are not yet resolved if they contain aliases with the ${...} operator. If you want to have a particular key resolved you have to ask the Environment directly again:

myEnv.getProperty( key );

Does this not work (assuming "ROUTERNAME" is the user name the router expects)?

net use Z: "\\10.0.1.1\DRIVENAME" /user:"ROUTERNAME" "PW"

Alternatively, you can use use a small VBScript:

Option Explicit
Dim u, p, s, l
Dim Network: Set Network= CreateObject("WScript.Network")

l = "Z:"
s = "\\10.0.1.1\DRIVENAME"

u = "ROUTERNAME"
p = "PW"

Network.MapNetworkDrive l, s, False, u, p

I would highly recommend the REST client Retrofit.

I have found this well written blog post extremely helpful, it also contains simple example code. The author uses Retrofit to make the network calls and Otto to implement a data bus pattern:

Hello i was have the same issue, but it is easly, just do this:

string cadena="96.23";

decimal NoDecimal=decimal.parse(cadena.replace(".",","))

I think this is beacuse the notation that accept C# on decimal numbers are with a ","

add this below script in ~/.bashrc and do please replace project name(projectname) with whatever the name you needed

function s() {
        array=($(gcloud projects list | awk /projectname/'{print $1}'))
        for i in "${!array[@]}";do printf "%s=%s\n" "$i" "${array[$i]}";done
        echo -e "\nenter the number to switch project:\c"
        read project
        [ ${array[${project}]} ] || { echo "project not exists"; exit 2; }
        printf "\n**** Running: gcloud config set project ${array[${project}]} *****\n\n"
        eval "gcloud config set project ${array[${project}]}"
}

'Truncate tableName' will fail on a table with key constraint defined. It will also not reindex the table AUTO_INCREMENT value. Instead, Delete all table entries and reset indexing back to 1 using this sql syntax:

DELETE FROM tableName;
ALTER TABLE tableName AUTO_INCREMENT = 1

We ran into this problem when working with node on Windows.

Rather than requiring anyone who attempts to run the app to set these variables, we provided a fallback within the application.

var environment = process.env.NODE_ENV || 'development';

In a production environment, we would define it per the usual methods (SET/export).

For me my mac OS is Mojave. and I'm facing the same issue for three days and in the end, I just write the correct path in the .bash_profile file which is like this:

    export PATH=/Users/[YOURNAME]/development/flutter/bin:$PATH

• note1: if u don't have .bash_profile create one and write the line above
• note2: zip your downloaded flutter SDK in [home]/development if you copy and paste this path

.  = This location
.. = Up a directory

So, ./foo.html is just foo.html. And it is optional, but may have relevance if a script generated the path (relevance to the script that is, not how the reference works).

As to why, no idea.

A reset will most certainly fix this:

ul { margin: 0; padding: 0; }

If I understand your problem correctly, you are calling a method instead of passing it as a parameter. Try the following:

myTimer.Elapsed += PlayMusicEvent;

where

public void PlayMusicEvent(object sender, ElapsedEventArgs e)
{
    music.player.Stop();
    System.Timers.Timer myTimer = (System.Timers.Timer)sender;
    myTimer.Stop();
}

But you need to think about where to store your note.

information is discarded in the compiling process. Even if a decompiler could produce the logical equivalent code with classes and everything (it probably can't), the self-documenting part is gone in optimized release code. No variable names, no routine names, no class names - just addresses.

Your file seems quite small (297 lines) so you can read and write them quite quickly. You refer to Excel CSV, which does not exists, and you show space delimited data in your example. Furthermore, Access is limited to 255 columns, and a CSV is not, so there is no guarantee this will work

Sub StripHeaderAndFooter()
Dim fs As Object ''FileSystemObject
Dim tsIn As Object, tsOut As Object ''TextStream
Dim sFileIn As String, sFileOut As String
Dim aryFile As Variant

    sFileIn = "z:\docs\FileName.csv"
    sFileOut = "z:\docs\FileOut.csv"

    Set fs = CreateObject("Scripting.FileSystemObject")
    Set tsIn = fs.OpenTextFile(sFileIn, 1) ''ForReading

    sTmp = tsIn.ReadAll

    Set tsOut = fs.CreateTextFile(sFileOut, True) ''Overwrite
    aryFile = Split(sTmp, vbCrLf)

    ''Start at line 3 and end at last line -1
    For i = 3 To UBound(aryFile) - 1
        tsOut.WriteLine aryFile(i)
    Next

    tsOut.Close

    DoCmd.TransferText acImportDelim, , "NewCSV", sFileOut, False
End Sub

Edit re various comments

It is possible to import a text file manually into MS Access and this will allow you to choose you own cell delimiters and text delimiters. You need to choose External data from the menu, select your file and step through the wizard.

About importing and linking data and database objects -- Applies to: Microsoft Office Access 2003

Introduction to importing and exporting data -- Applies to: Microsoft Access 2010

Once you get the import working using the wizards, you can save an import specification and use it for you next DoCmd.TransferText as outlined by @Olivier Jacot-Descombes. This will allow you to have non-standard delimiters such as semi colon and single-quoted text.

in case you would like to print all file contents: find . -type f -exec cat {} +

First you need an object

public class MyObject {
  public string Id {get;set;}
  public string Text {get;set;}
  ...
}

Then in here

    using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {

        using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
            JavaScriptSerializer js = new JavaScriptSerializer();
            var objText = reader.ReadToEnd();
            MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
        }

    }

I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.

JavaScriptSerializer System.Web.Script.Serialization

There's a python module especially made for reading and writing to and from binary encoded data called 'struct'. Since versions of Python under 2.6 doesn't support str.format, a custom method needs to be used to create binary formatted strings.

import struct

# binary string
def bstr(n): # n in range 0-255
    return ''.join([str(n >> x & 1) for x in (7,6,5,4,3,2,1,0)])

# read file into an array of binary formatted strings.
def read_binary(path):
    f = open(path,'rb')
    binlist = []
    while True:
        bin = struct.unpack('B',f.read(1))[0] # B stands for unsigned char (8 bits)
        if not bin:
            break
        strBin = bstr(bin)
        binlist.append(strBin)
    return binlist

You can use rfind() or rindex()
^{Python2 links: rfind() rindex()}

>>> s = 'Hello StackOverflow Hi everybody'

>>> print( s.rfind('H') )
20

>>> print( s.rindex('H') )
20

>>> print( s.rfind('other') )
-1

>>> print( s.rindex('other') )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: substring not found

The difference is when the substring is not found, rfind() returns -1 while rindex() raises an exception ValueError (Python2 link: ValueError).

If you do not want to check the rfind() return code -1, you may prefer rindex() that will provide an understandable error message. Else you may search for minutes where the unexpected value -1 is coming from within your code...

Example: Search of last newline character

>>> txt = '''first line
... second line
... third line'''

>>> txt.rfind('\n')
22

>>> txt.rindex('\n')
22

Socket connections in Android are the same as in Java: http://www.oracle.com/technetwork/java/socket-140484.html

Things you need to be aware of:

1. If phone goes to sleep your app will no longer execute, so socket will eventually timeout. You can prevent this with wake lock. This will eat devices battery tremendously - I know I wouldn't use that app.
2. If you do this constantly, even when your app is not active, then you need to use Service.
3. Activities and Services can be killed off by OS at any time, especially if they are part of an inactive app.

Take a look at AlarmManager, if you need scheduled execution of your code.

Do you need to run your code and receive data even if user does not use the app any more (i.e. app is inactive)?

You get this error because your variable subjects is an Object not Array, you can use map() only for Array.

In case of mapping object you can do this:

{ 
    Object.keys(subjects).map((item, i) => (
        <li className="travelcompany-input" key={i}>
            <span className="input-label">{ subjects[item].name }</span>
        </li>
    ))
}  

There is one characteristic about inline-block which may not be straight-forward though. That is that the default value for vertical-align in CSS is baseline. This may cause some unexpected alignment behavior. Look at this article.

http://www.brunildo.org/test/inline-block.html

Instead, when you do a float:left, the divs are independent of each other and you can align them using margin easily.

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

Simple workaround is to open the file and simply press save button in Excel (no need to change the format). once saved in excel it will start to work and you should be able to see its sheets in the DFT.

Broadcast Receivers timeout after 10 seconds. Possibly your doing an asynchronous call (wrong) from a broadcast receiver and 4.3 actually detects it.

attrib -h -r -s /s /d j:*.*

where j is the drive letter... unlocks all the locked stuff in j drive

if u want to make it specific..then go to a specific location using cmd and then type

attrib -h -r -s /s /d "foldername"

it can also be used to lock drives or folders just alter "-" with "+"

attrib +h +r +s /s /d "foldername"

You need remove path.moveTo after first initial.

Path path = new Path();
path.moveTo(point1_returned.x, point1_returned.y);
path.lineTo(point2_returned.x, point2_returned.y);
path.lineTo(point3_returned.x, point3_returned.y);
path.lineTo(point1_returned.x, point1_returned.y);
path.close();

It looks like the SQL Server doesn't have permission to access file C:\backup.bak. I would check the permissions of the account that is assigned to the SQL Server service account.

As part of the solution, you may want to save your backup files to somewhere other that the root of the C: drive. That might be one reason why you are having permission problems.

Use double quotes while using BASH variables.

mysql --user="$user" --password="$password" --database="$database" --execute="DROP DATABASE $user; CREATE DATABASE $database;"

BASH doesn't expand variables in single quotes.

Just to extend the pratical scope of the question and as an appendix to the given answers: Sometimes one might find it necessary to specify the selectors a little bit more.

By defining the the full span as display:inline-block you might have a hard time displaying images.

Therefore I prefer to define a span like so:

span {
  display:block;
  width:150px;
  word-wrap:break-word;      
}
p span, a span,
h1 span, h2 span, h3 span, h4 span, h5 span {
  display:inline-block;
}
img{
  display:block;
}

I created an online tool to do this. Simply paste any dependency in pom file format, and the dependency tree for that artifact is generated, based on the central maven repository.

The command has to be entered in the directory of the repository. The error is complaining that your current directory isn't a git repo

1. Are you in the right directory? Does typing ls show the right files?
2. Have you initialized the repository yet? Typed git init? (git-init documentation)

Either of those would cause your error.

it's also possible to create a unique constraint of more than 1 column:

ALTER TABLE the_table 
    ADD CONSTRAINT constraint_name UNIQUE (column1, column2);

You can control client cache with HTTP headers. This works in any web framework.

You can set the directives these headers to have fine grained control over how and when to enable|disable cache:

• Cache-Control
• Surrogate-Control
• Expires
• ETag (very good one)
• Pragma (if you want to support old browsers)

Good caching is good, but very complex, in all computer systems. Take a look at https://helmetjs.github.io/docs/nocache/#the-headers for more information.

This works for me.

@{ var dic = new Dictionary<string, string>() { { "checked", "" } }; }
@Html.RadioButtonFor(_ => _.BoolProperty, true, (@Model.BoolProperty)? dic: null) Yes
@Html.RadioButtonFor(_ => _.BoolProperty, false, ([email protected])? dic: null) No

Update MyTable
Set Value = (
                Select Min( T2.Value )
                From MyTable As T2
                Where T2.Id <> MyTable.Id
                    And T2.Name = MyTable.Name
                )
Where ( Value Is Null Or Value = '' )
    And Exists  (
                Select 1
                From MyTable As T3
                Where T3.Id <> MyTable.Id
                    And T3.Name = MyTable.Name
                )

You can call the stat() function and use the S_ISREG() macro on the st_mode field of the stat structure in order to determine if your path points to a regular file:

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

int is_regular_file(const char *path)
{
    struct stat path_stat;
    stat(path, &path_stat);
    return S_ISREG(path_stat.st_mode);
}

Note that there are other file types besides regular and directory, like devices, pipes, symbolic links, sockets, etc. You might want to take those into account.

YearMonth

For completeness, and more elegant in my opinion, see this use of YearMonth class.

YearMonth month = YearMonth.from(date);
LocalDate start = month.atDay(1);
LocalDate end   = month.atEndOfMonth();

For the first & last day of the current month, this becomes:

LocalDate start = YearMonth.now().atDay(1);
LocalDate end   = YearMonth.now().atEndOfMonth();

 string AssemblyID = Assembly.GetEntryAssembly().GetCustomAttribute<GuidAttribute>().Value;

or, VB.NET:

  Dim AssemblyID As String = Assembly.GetEntryAssembly.GetCustomAttribute(Of GuidAttribute).Value

Check your bucket location in the console, then use this as reference to which endpoint to use: http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region

Wildcard works for me also, but I'd like to give a side note for those using directory variables. Always use slash for folder tree (not backslash), otherwise it will fail:

BASEDIR = ../..
SRCDIR = $(BASEDIR)/src
INSTALLDIR = $(BASEDIR)/lib

MODULES = $(wildcard $(SRCDIR)/*.cpp)
OBJS = $(wildcard *.o)

$.get(str, function(data){ 
            var sary=data.split('|');
            document.getElementById("select1").options.length = 0;
            document.getElementById("select1").options[0] = new Option('Select a State');
            for(i=0;i<sary.length-1;i++){
                document.getElementById("select1").options[i+1] = new Option(sary[i]);
                document.getElementById("select1").options[i+1].value = sary[i];
            }
            });

A view is a virtual table, which provides access to a subset of column from one or more table. A view can derive its data from one or more table. An output of query can be stored as a view. View act like small a table but it does not physically take any space. View is good way to present data in particular users from accessing the table directly. A view in oracle is nothing but a stored sql scripts. Views itself contain no data.

None of the solutions here worked for me out of the box, but it was most likely due my lack of experience with VBA. It might also be because I simply copied and pasted some of the functions above, not knowing details that maybe are necessary to make them work on a VBA for applications environment.

My needs were simply to send xmlhttp requests using urls that contained some special characters of the Norwegian language. Some of the solutions above encode even colons, which made the urls unsuitable for what I needed.

I then decided to write my own URLEncode function. It does not use more clever programming such as the one from @ndd and @Tom. I am not a very experienced programmer, but I had to make this done sooner.

I realized that the problem was that my server didn't accept UTF-16 encodings, so I had to write a function that would convert UTF-16 to UTF-8. A good source of information was found here and here.

I haven't tested it extensively to check if it works with url with characters that have higher unicode values and which would produce more than 2 bytes of utf-8 characters. I am not saying it will decode everything that needs to be decoded (but it is easy to modify to include/exclude characters on the select case statement) nor that it will work with higher characters, as I haven't fully tested. But I am sharing the code because it might help someone who is trying to understand the issue.

Any comments are welcome.

For the sake of completeness: the previous answers tell how to set the upstream branch, but not how to see it.

There are a few ways to do this:

git branch -vv shows that info for all branches. (formatted in blue in most terminals)

cat .git/config shows this also.

For reference:

• how do I get git to show me which branches are tracking what?
• What is this branch tracking (if anything) in git?

There are different ways but simplest would be to use the space-between see the example at the end

#container {    
    border: solid 1px #000;
    display: flex;    
    flex-direction: row;
    justify-content: space-between;
    padding: 10px;
    height: 50px;
}

.item {
    width: 20%;
    border: solid 1px #000;
    text-align: center;
}

see the example

As explained in "Deleting your master branch" by Matthew Brett, you need to change your GitHub repo default branch.

You need to go to the GitHub page for your forked repository, and click on the “Settings” button.

Click on the "Branches" tab on the left hand side. There’s a “Default branch” dropdown list near the top of the screen.

From there, select placeholder (where placeholder is the dummy name for your new default branch).

Confirm that you want to change your default branch.

Now you can do (from the command line):

git push origin :master

Or, since 2012, you can delete that same branch directly on GitHub:

That was announced in Sept. 2013, a year after I initially wrote that answer.

For small changes like documentation fixes, typos, or if you’re just a walking software compiler, you can get a lot done in your browser without needing to clone the entire repository to your computer.

Note: for BitBucket, Tum reports in the comments:
