This new package looks nice http://cran.r-project.org/web/packages/openxlsx/openxlsx.pdf It doesn't require rJava and is using 'Rcpp' for speed.

If the current directory is empty, then this will work:

git clone <repository> foo; mv foo/* foo/.git* .; rmdir foo

Get a list of properties from model using _.keys(), and use _.pick() to extract the properties from credentials to a new object:

var model = {
   fname:null,
   lname:null
};

var credentials = {
    fname:"xyz",
    lname:"abc",
    age:23
};

var result = _.pick(credentials, _.keys(model));

console.log(result);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.16.4/lodash.min.js"></script>

If you don't want to use Lodash, you can use Object.keys(), and Array.prototype.reduce():

var model = {
   fname:null,
   lname:null
};

var credentials = {
    fname:"xyz",
    lname:"abc",
    age:23
};

var result = Object.keys(model).reduce(function(obj, key) {
  obj[key] = credentials[key];
  return obj;
}, {});

console.log(result);

I had the same issue until I added the following lib array in typeScript 3.0.1

tsconfig.json

{
  "compilerOptions": {
    "outDir": "lib",
    "module": "commonjs",
    "allowJs": false,
    "declaration": true,
    "target": "es5",
    "lib": ["dom", "es2015", "es5", "es6"],
    "rootDir": "src"
  },
  "include": ["./**/*"],
  "exclude": ["node_modules", "**/*.spec.ts"]
}

EDIT 11/19/19: For iOS 13, just use UICollectionViewCompositionalLayout with estimated heights. Don't waste your time dealing with this broken API.

After struggling with this for some time, I noticed that resizing does not work for UITextViews if you don't disable scrolling:

let textView = UITextView()
textView.scrollEnabled = false

A timestamp does not have "a format".

The recommended way to deal with timestamps is to use a PreparedStatement where you just pass a placeholder in the SQL and pass a "real" object through the API of your programming language. As I don't know Python, I don't know if it supports PreparedStatements and how the syntax for that would be.

If you want to put a timestamp literal into your generated SQL, you will need to follow some formatting rules when specifying the value (a literal does have a format).

Ivan's method will work, although I'm not 100% sure if it depends on the configuration of the PostgreSQL server.

A configuration (and language) independent solution to specify a timestamp literal is the ANSI SQL standard:

 INSERT INTO some_table 
 (ts_column) 
 VALUES 
 (TIMESTAMP '2011-05-16 15:36:38');

Yes, that's the keyword TIMESTAMP followed by a timestamp formatted in ISO style (the TIMESTAMP keyword defines that format)

The other solution would be to use the to_timestamp() function where you can specify the format of the input literal.

 INSERT INTO some_table 
 (ts_column) 
 VALUES 
 (to_timestamp('16-05-2011 15:36:38', 'dd-mm-yyyy hh24:mi:ss'));

The top answer (if e.errno == errno.EPIPE:) here didn't really work for me. I got:

AttributeError: 'BrokenPipeError' object has no attribute 'EPIPE'

However, this ought to work if all you care about is ignoring broken pipes on specific writes. I think it's safer than trapping SIGPIPE:

try:
    # writing, flushing, whatever goes here
except BrokenPipeError:
    exit( 0 )

You obviously have to make a decision as to whether your code is really, truly done if you hit the broken pipe, but for most purposes I think that's usually going to be true. (Don't forget to close file handles, etc.)

Restartable mode (/Z) has to do with a partially-copied file. With this option, should the copy be interrupted while any particular file is partially copied, the next execution of robocopy can pick up where it left off rather than re-copying the entire file.

That option could be useful when copying very large files over a potentially unstable connection.

Backup mode (/B) has to do with how robocopy reads files from the source system. It allows the copying of files on which you might otherwise get an access denied error on either the file itself or while trying to copy the file's attributes/permissions. You do need to be running in an Administrator context or otherwise have backup rights to use this flag.

Set texts with different sizes and styles, and size and style for texts from cells ( with Range)

Sub EmailManuellAbsenden()

Dim ghApp As Object
Dim ghOldBody As String
Dim ghNewBody As String

Set ghApp = CreateObject("Outlook.Application")
With ghApp.CreateItem(0)
.To = Range("B2")
.CC = Range("B3")
.Subject = Range("B4")
.GetInspector.Display
 ghOldBody = .htmlBody

 ghNewBody = "<font style=""font-family: Calibri; font-size: 11pt;""/font>" & _
 "<font style=""font-family: Arial; font-size: 14pt;"">Arial Text 14</font>" & _

This more verbose solution provides greater control on what happens in case of duplicate maximum value (in this example, it will take one of the corresponding rows randomly)

library(dplyr)
df %>% group_by(A, B) %>%
  mutate(the_rank  = rank(-value, ties.method = "random")) %>%
  filter(the_rank == 1) %>% select(-the_rank)

$("input").click(function(){
        var name = $(this).attr("name");
        $('input[name="' + name + '"]').hide();    
    });   

Also works with ID:

var id = $(this).attr("id");
$('input[id="' + id + '"]').hide();

when, (sometimes)

$('input#' + id).hide();

does not work, as it should.

You can even do both:

$('input[name="' + name + '"][id="' + id + '"]').hide();

Yes, by adding an extra wrapping element. Assign the desired line-through color to an outer element, then the desired text color to the inner element. For example:

<span style='color:red;text-decoration:line-through'>_x000D_
  <span style='color:black'>black with red strikethrough</span>_x000D_
</span>

...or...

<strike style='color:red'>_x000D_
  <span style='color:black'>black with red strikethrough<span>_x000D_
</strike>

(Note, however, that <strike> is considered deprecated in HTML4 and obsolete in HTML5 (see also W3.org). The recommended approach is to use <del> if a true meaning of deletion is intended, or otherwise to use an <s> element or style with text-decoration CSS as in the first example here.)

To make the strikethrough appear for a:hover, an explicit stylesheet (declared or referenced in <HEAD>) must be used. (The :hover pseudo-class can't be applied with inline STYLE attributes.) For example:

<head>_x000D_
  <style>_x000D_
    a.redStrikeHover:hover {_x000D_
      color:red;_x000D_
      text-decoration:line-through;_x000D_
    }_x000D_
  </style>_x000D_
</head>_x000D_
<body>_x000D_
  <a href='#' class='redStrikeHover'>_x000D_
    <span style='color:black'>hover me</span>_x000D_
  </a>_x000D_
</body>

When I'm just testing a string to see if it is a GUID, I don't really want to create a Guid object that I don't need. So...

public static class GuidEx
{
    public static bool IsGuid(string value)
    {
        Guid x;
        return Guid.TryParse(value, out x);
    }
}

And here's how you use it:

string testMe = "not a guid";
if (GuidEx.IsGuid(testMe))
{
...
}

Use Manatee.Json https://github.com/gregsdennis/Manatee.Json/wiki/Usage

And you can convert the entire object to a string, filename.json is expected to be located in documents folder.

        var text = File.ReadAllText("filename.json");
        var json = JsonValue.Parse(text);

        while (JsonValue.Null != null)
        {
            Console.WriteLine(json.ToString());

        }
        Console.ReadLine();

The syntax of ng-style is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:

<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>

And then in your controller:

$scope.width = '900px';
$scope.bgColor = 'red';

This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.

In spark version >= 3 you can convert pandas dataframes to pyspark dataframe in one line

use spark.createDataFrame(pandasDF)

dataset = pd.read_csv("data/AS/test_v2.csv")

sparkDf = spark.createDataFrame(dataset);

if you are confused about spark session variable, spark session is as follows

sc = SparkContext.getOrCreate(SparkConf().setMaster("local[*]"))

spark = SparkSession \
    .builder \
    .getOrCreate()

Right click the project and give maven build,maven clean,maven generate resource and maven install.The jar file will automatically generate.

page-break-inside: avoid; does not seem to always work. It seems to take into account the height and positioning of container elements.

For example, inline-block elements that are taller than the page will get clipped.

I was able to restore working page-break-inside: avoid; functionality by identifying a container element with display: inline-block and adding:

@media print {
    .container { display: block; } /* this is key */

    div, p, ..etc { page-break-inside: avoid; }
}

Hope this helps folks who complain that "page-break-inside does not work".

The user agent string is a text that the browsers themselves send to the webserver to identify themselves, so that websites can send different content based on the browser or based on browser compatibility.

Mozilla is a browser rendering engine (the one at the core of Firefox) and the fact that Chrome and IE contain the string Mozilla/4 or /5 identifies them as being compatible with that rendering engine.

Use setText(str) method of JLabel to dynamically change text displayed. In actionPerform of button write this:

jLabel.setText("new Value");

A simple demo code will be:

    JFrame frame = new JFrame("Demo");
    frame.setLayout(new BorderLayout());
    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    frame.setSize(250,100);

    final JLabel label = new JLabel("flag");
    JButton button = new JButton("Change flag");
    button.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent arg0) {
            label.setText("new value");
        }
    });

    frame.add(label, BorderLayout.NORTH);
    frame.add(button, BorderLayout.CENTER);
    frame.setVisible(true);

Basically React.useState(0) magically sees that it should return the tuple count and setCount (a method to change count). The parameter useState takes sets the initial value of count.

  const [count, setCount] = React.useState(0);
  const [count2, setCount2] = React.useState(0);

  // increments count by 1 when first button clicked
  function handleClick(){
    setCount(count + 1);
  } 

  // increments count2 by 1 when second button clicked
  function handleClick2(){
    setCount2(count2 + 1);
  } 

  return (
    <div>
      <h2>A React counter made with the useState Hook!</h2>
      <p>You clicked {count} times</p>
      <p>You clicked {count2} times</p>
      <button onClick={handleClick}>
        Click me
      </button> 
      <button onClick={handleClick2}>
        Click me2
      </button>
  );

Based off Enmanuel Duran's example, but shows two counters and writes lambda functions as normal functions, so some people might understand it easier.

I also had a working system that suddenly stopped working with the described error.

After furtling around in my /lib/modules it would appear that the vboxvfs module is no more. Instead modprobe vboxsf was the required incantation to get things restarted.

Not sure when that change ocurred, but it caught me out.

Try this:

// convert string to stream
byte[] byteArray = Encoding.UTF8.GetBytes(contents);
//byte[] byteArray = Encoding.ASCII.GetBytes(contents);
MemoryStream stream = new MemoryStream(byteArray);

and

// convert stream to string
StreamReader reader = new StreamReader(stream);
string text = reader.ReadToEnd();

To backup a single database from the command line, use osql or sqlcmd.

"C:\Program Files\Microsoft SQL Server\90\Tools\Binn\osql.exe" 
    -E -Q "BACKUP DATABASE mydatabase TO DISK='C:\tmp\db.bak' WITH FORMAT"

You'll also want to read the documentation on BACKUP and RESTORE and general procedures.

As stated by the other answers, "%03d" % number works pretty well, but it goes against the rubocop ruby style guide:

Favor the use of sprintf and its alias format over the fairly cryptic String#% method

We can obtain the same result in a more readable way using the following:

format('%03d', number)

Added a few optional parameters for creating "future safe" sequences.

CREATE SEQUENCE <NAME>
  START WITH 1
  INCREMENT BY 1
  NO MAXVALUE
  NO CYCLE
  CACHE 10;

If you need the "week ending" date this will work as well. This will count the number of records for each week. Example: If three work orders were created between (inclusive) 1/2/2010 and 1/8/2010 and 5 were created between (inclusive) 1/9/2010 and 1/16/2010 this would return:

3 1/8/2010
5 1/16/2010

I had to use the extra DATE() function to truncate my datetime field.

SELECT COUNT(*), DATE_ADD( DATE(wo.date_created), INTERVAL (7 - DAYOFWEEK( wo.date_created )) DAY) week_ending
FROM work_order wo
GROUP BY week_ending;

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin('a.user', 'u')
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.

If no association is available, then the query looks like following

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin(
            'User\Entity\User',
            'u',
            \Doctrine\ORM\Query\Expr\Join::WITH,
            'a.user = u.id'
        )
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

This will produce a resultset that looks like following:

array(
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    // ...
)

May be a bit late but in my case i had to put the id in the 2nd anonymous object. This is because the 1st one is for route values i.e the return Url.

@using (Html.BeginForm("Login", "Account", new {  ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { id = "signupform", role = "form" }))

Hope this can help somebody :)

I would do it by creating a variable that points to the nodes that have the proper value in Value1 then referring to t

<xsl:variable name="myVarANode" select="root//DataSet/Data[@Value1='2']" />
<xsl:value-of select="$myVarANode/@Value2"/>

Everyone else's answers are right too - more right in fact since I didn't notice the extra slash in your XPATH that would mess things up. Still, this will also work , and might work for different things, so keep this method in your toolbox.

The other provided solutions are great when you want to add only 2 byte arrays, but if you want to keep appending several byte[] chunks to make a single:

byte[] readBytes ; // Your byte array .... //for eg. readBytes = "TestBytes".getBytes();

ByteArrayBuffer mReadBuffer = new ByteArrayBuffer(0 ) ; // Instead of 0, if you know the count of expected number of bytes, nice to input here

mReadBuffer.append(readBytes, 0, readBytes.length); // this copies all bytes from readBytes byte array into mReadBuffer
// Any new entry of readBytes, you can just append here by repeating the same call.

// Finally, if you want the result into byte[] form:
byte[] result = mReadBuffer.buffer();

Wes McKinney (pandas' author) in Python for Data Analysis provides the following recipe:

groups = dict(list(gb))

which returns a dictionary whose keys are your group labels and whose values are DataFrames, i.e.

groups['foo']

will yield what you are looking for:

     A         B   C
0  foo  1.624345   5
2  foo -0.528172  11
4  foo  0.865408  14

well i found out the mistake i was committing i was adding a group to the project instead of adding real directory for more instructions

It dipends on which distribution you are in general but... You have to install the php-curl module and then enable it on php.ini like you did in windows. Once you are done remember to restart apache demon!

You can just create a function to check if the variable exists, else will return a default value :

function isSet(element, defaultVal){

    if(typeof element != 'undefined'){

        return element;

    }

    console.log('one missing element');

    return defaultVal;
}

And use it in a variable check:

var variable = isSet(variable, 'Default value');

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.

I've assumed a named JSONArray is a JSONObject and accessed the data from the server to populate an Android GridView. For what it is worth my method is:

private String[] fillTable( JSONObject jsonObject ) {
   String[] dummyData = new String[] {"1", "2", "3", "4", "5", "6", "7","1", "2", "3", "4", "5", "6", "7","1", "2", "3", "4", "5", "6", "7", };
  if( jsonObject != null ) {
      ArrayList<String> data = new ArrayList<String>();
      try {
          // jsonArray looks like { "everything" : [{}, {},] }
          JSONArray jsonArray = jsonObject.getJSONArray( "everything" );
          int number = jsonArray.length(); //How many rows have got from the database?
          Log.i( Constants.INFORMATION, "Number of ows returned:  " + Integer.toString( number ) );
                  // Array elements look like this
          //{"success":1,"error":0,"name":"English One","owner":"Tutor","description":"Initial Alert","posted":"2013-08-09 15:35:40"}
          for( int element = 0; element < number; element++ ) { //visit each element
             JSONObject jsonObject_local = jsonArray.getJSONObject( element );
             //  Overkill on the error/success checking
             Log.e("JSON SUCCESS", Integer.toString( jsonObject_local.getInt(Constants.KEY_SUCCESS) ) );
             Log.e("JSON ERROR", Integer.toString( jsonObject_local.getInt(Constants.KEY_ERROR) ) );
                if ( jsonObject_local.getInt( Constants.KEY_SUCCESS) == Constants.JSON_SUCCESS ) {
                   String name = jsonObject_local.getString( Constants.KEY_NAME );
                   data.add( name );
                   String owner = jsonObject_local.getString( Constants.KEY_OWNER );
                   data.add( owner );
                   String description = jsonObject_local.getString( Constants.KEY_DESCRIPTION );
                   Log.i( "DESCRIPTION", description );
                   data.add( description ); 
                   String date = jsonObject_local.getString( Constants.KEY_DATE );
                   data.add( date );
                }
                else {
                    for( int i = 0; i < 4; i++ ) {
                        data.add( "ERROR" );
                    }
                }
          }
  }  //JSON object is null
  catch ( JSONException jsone) {
      Log.e( "JSON EXCEPTION", jsone.getMessage() );
  }
      dummyData = data.toArray( dummyData );
  }
  return dummyData;

}

No reason but indifference, I'd guess.

Such query strings are usually generated by a graphical query tool. The user joins a few tables, adds a filter, a sort order, and tests the results. Since the user may want to save the query as a view, the tool adds a TOP 100 PERCENT. In this case, though, the user copies the SQL into his code, parameterized the WHERE clause, and hides everything in a data access layer. Out of mind, out of sight.

Generic functional form

def select_columns(data_frame, column_names):
    new_frame = data_frame.loc[:, column_names]
    return new_frame

Specific for your problem above

selected_columns = ['A', 'C', 'D']
new = select_columns(old, selected_columns)

Here's what I've done:

.resize {
    width: 400px;
    height: auto;
}

.resize {
    width: 300px;
    height: auto;
}

<img class="resize" src="example.jpg"/>

This will keep the image aspect ratio the same.

I've done it this way in the past, JsFiddle:

CSS:

.radio-option {
    cursor: pointer;
    height: 23px;
    width: 23px;
    background: url(../images/checkbox2.png) no-repeat 0px 0px;
}

.radio-option.click {
    background: url(../images/checkbox1.png) no-repeat 0px 0px;
}

HTML:

<li><div class="radio-option"></div></li>
<li><div class="radio-option"></div></li>
<li><div class="radio-option"></div></li>
<li><div class="radio-option"></div></li>
<li><div class="radio-option"></div></li>

jQuery:

<script>
    $(document).ready(function() {
        $('.radio-option').click(function () {
            $(this).not(this).removeClass('click');
            $(this).toggleClass("click");
        });
    });
</script>

you can use :

Process.GetCurrentProcess().MainWindowHandle

Use this code

        TextView textView = new TextView(YourActivity.this);
        textView.setGravity(Gravity.CENTER | Gravity.TOP);
        textView.setText("some text");

you can run flutter clean command

Rails 5 comes with an or method. (link to documentation)

This method accepts an ActiveRecord::Relation object. eg:

User.where(first_name: 'James').or(User.where(last_name: 'Scott'))

Both do different things.

The first creates an object with automatic storage duration. It is created, used, and then goes out of scope when the current block ({ ... }) ends. It's the simplest way to create an object, and is just the same as when you write int x = 0;

The second creates an object with dynamic storage duration and allows two things:

• Fine control over the lifetime of the object, since it does not go out of scope automatically; you must destroy it explicitly using the keyword delete;

• Creating arrays with a size known only at runtime, since the object creation occurs at runtime. (I won't go into the specifics of allocating dynamic arrays here.)

Neither is preferred; it depends on what you're doing as to which is most appropriate.

Use the former unless you need to use the latter.

Your C++ book should cover this pretty well. If you don't have one, go no further until you have bought and read, several times, one of these.

Good luck.

Your original code is broken, as it deletes a char array that it did not new. In fact, nothing newd the C-style string; it came from a string literal. deleteing that is an error (albeit one that will not generate a compilation error, but instead unpredictable behaviour at runtime).

Usually an object should not have the responsibility of deleteing anything that it didn't itself new. This behaviour should be well-documented. In this case, the rule is being completely broken.

AntiGrain Geometry (AGG). http://www.antigrain.com/. Its an opensource 2D vector graphics library. Its a standalone library with no additional dependencies. Has good documentation. Python plotting library matplotlib uses AGG as one of backends.

that is referring to the expected dtype of your image

On the command line execute:

php --ini

You will get something like:

Configuration File (php.ini) Path: /etc/php5/cli
Loaded Configuration File:         /etc/php5/cli/php.ini
Scan for additional .ini files in: /etc/php5/cli/conf.d
Additional .ini files parsed:      /etc/php5/cli/conf.d/curl.ini,
/etc/php5/cli/conf.d/pdo.ini,
/etc/php5/cli/conf.d/pdo_sqlite.ini,
/etc/php5/cli/conf.d/sqlite.ini,
/etc/php5/cli/conf.d/sqlite3.ini,
/etc/php5/cli/conf.d/xdebug.ini,
/etc/php5/cli/conf.d/xsl.ini

That's from my local dev-machine. However, the second line is the interesting one. If there is nothing mentioned, have a look at the first one. That is the path, where PHP looks for the php.ini.

You can grep the same information using phpinfo() in a script and call it with a browser. Its mentioned in the first block of the output. php -i does the same for the command line, but its quite uncomfortable.

var without2 = (arr, args) => arr.filter(v => v.id !== args.id); Example:

without2([{id:1},{id:1},{id:2}],{id:2})

Result: without2([{id:1},{id:1},{id:2}],{id:2})

I started with FXRuby because it had a book.

When implementing the onClickListener, you can use v.getContext.startActivity.

btn.setOnClickListener(new OnClickListener() {                  
    @Override
    public void onClick(View v) {
        v.getContext().startActivity(PUT_YOUR_INTENT_HERE);
    }
});

Both means "every item in a set of two things". The two things being "left" and "right"

Note: you might have to adjust the height for different fonts.

new_data <- data %>% filter_all(any_vars(is.na(.))) 

This should create a new data frame (new_data) with only the missing values in it.

Works best to keep a track of values that you might later drop because they had some columns with missing observations (NA).

setAllowUrlEncodedSlash(true) didn't work for me. Still internal method isNormalized return false when having double slash.

I replaced StrictHttpFirewall with DefaultHttpFirewall by having the following code only:

@Bean
public HttpFirewall defaultHttpFirewall() {
    return new DefaultHttpFirewall();
}

Working well for me.
Any risk by using DefaultHttpFirewall?

I find it important to note that python 3 defines the opening modes differently to the answers here that were correct for Python 2.

The Pyhton 3 opening modes are:

'r' open for reading (default)
'w' open for writing, truncating the file first
'x' open for exclusive creation, failing if the file already exists
'a' open for writing, appending to the end of the file if it exists
----
'b' binary mode
't' text mode (default)
'+' open a disk file for updating (reading and writing)
'U' universal newlines mode (for backwards compatibility; should not be used in new code)

The modes r, w, x, a are combined with the mode modifiers b or t. + is optionally added, U should be avoided.

As I found out the hard way, it is a good idea to always specify t when opening a file in text mode since r is an alias for rt in the standard open() function but an alias for rb in the open() functions of all compression modules (when e.g. reading a *.bz2 file).

Thus the modes for opening a file should be:

rt / wt / xt / at for reading / writing / creating / appending to a file in text mode and

rb / wb / xb / ab for reading / writing / creating / appending to a file in binary mode.

Use + as before.

Just add AsEnumerable() andToList() , so it looks like this

db.Favorites
    .Where(x => x.userId == userId)
    .Join(db.Person, x => x.personId, y => y.personId, (x, y).ToList().AsEnumerable()

ToList().AsEnumerable()

For anyone trying to get this working using the Sysdeo Eclipse Tomcat plugin, try the following steps (I used Sysdeo Tomcat Plugin 3.3.0, Eclipse Kepler, and Tomcat 7.0.53 to construct these steps):

1. Window --> Preferences --> Expand the Tomcat node in the tree --> JVM Settings
2. Under "Append to JVM Parameters", click the "Add" button.
3. In the "New Tomcat JVM parameter" popup, enter -Djava.util.logging.config.file="{TOMCAT_HOME}\conf\logging.properties", where {TOMCAT_HOME} is the path to your Tomcat directory (example: C:\Tomcat\apache-tomcat-7.0.53\conf\logging.properties). Click OK.
4. Under "Append to JVM Parameters", click the "Add" button again.
5. In the "New Tomcat JVM parameter" popup, enter -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager. Click OK.
6. Click OK in the Preferences window.
7. Make the adjustments to the {TOMCAT_HOME}\conf\logging.properties file as specified in the question above.
8. The next time you start Tomcat in Eclipse, you should see the scanned .jars listed in the Eclipse Console instead of the "Enable debug logging for this logger" message. The information should also be logged in {TOMCAT_HOME}\logs\catalina.yyyy-mm-dd.log.

I'll add a bit hint: it seems what you pass as the key value of a header depends on your authorization type, in my case that was PRIVATE-TOKEN

header = {'PRIVATE-TOKEN': 'my_token'}
response = requests.get(myUrl, headers=header)

Using Guava library, another option is to convert the Iterable to a List.

List list = Lists.newArrayList(some_iterator);
int count = list.size();

Use this if you need also to access the elements of the iterator after getting its size. By using Iterators.size() you no longer can access the iterated elements.

Although the z-index of the .modal is higher than that of the .modal-backdrop, that .modal is in a parent div #content-wrap which has a lower z-index than .modal-backdrop (z-index: 1002 vs z-index: 1030).

Because the parent has lower z-index than the .modal-backdrop everything in it will be behind the modal, irrespective of any z-index given to the children.

If you remove the z-index you have set on both the body div#fullContainer #content-wrap and also on the #ctrlNavPanel, everything seems to work ok.

body div#fullContainer #content-wrap {
  background: #ffffff;
  bottom: 0;
  box-shadow: -5px 0px 8px #000000;
  position: absolute;
  top: 0;
  width: 100%;
}

#ctrlNavPanel {
  background: #333333;
  bottom: 0;
  box-sizing: content-box;
  height: 100%;
  overflow-y: auto;
  position: absolute;
  top: 0;
  width: 250px;
}

NOTE: I think that you may have initially used z-indexes on the #content-wrap and #ctrlNavPanel to ensure the nav sits behind, but that's not necessary because the nav element comes before the content-wrap in the HTML, so you only need to position them, not explicitly set a stacking order.

EDIT As Schmalzy picked up on, the links are no longer clickable. This is because the full-container is 100% wide and so covers the navigation. The quickest way to fix this is to place the navigation inside that div:

<div id="fullContainer">
  <aside id="ctrlNavPanel">
    <ul class="nav-link-list">
      <li><label>Menu</label></li>
      <li><a href="/"><span class="fa fa-lg fa-home"></span> Home</a></li>
      <li><a><span class="fa fa-lg fa-group"></span>About Us</a></li>
      <li><a><span class="fa fa-lg fa-book"></span> Contacts</a></li>
    </ul>
  </aside>
  <div id="content-wrap">
    ...
  </div>
</div>

DEMO HERE

If the element is currently not visible on the page, you can use the native scrollIntoView() method.

$('#div_' + element_id)[0].scrollIntoView( true );

Where true means align to the top of the page, and false is align to bottom.

Otherwise, there's a scrollTo() plugin for jQuery you can use.

Or maybe just get the top position()^(docs) of the element, and set the scrollTop()^(docs) to that position:

var top = $('#div_' + element_id).position().top;
$(window).scrollTop( top );

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

Use the attribute onkeyup="myFunction()" in the <input> of your html.

Cells(1,1).Value2 = "'123,456"

note the single apostrophe before the number - this will signal to excel that whatever follows has to be interpreted as text.

If column number are varing you can use this

package com.org.tests;
import org.apache.poi.xssf.usermodel.*;
import java.io.FileInputStream;
import java.io.IOException;

public class ExcelSimpleTest 
{   
    String path;
    public FileInputStream fis = null;
    private XSSFWorkbook workbook = null;
    private XSSFSheet sheet = null;
    private XSSFRow row   =null;
    private XSSFCell cell = null;

    public ExcelSimpleTest() throws IOException
    {
        path = System.getProperty("user.dir")+"\\resources\\Book1.xlsx";
        fis = new FileInputStream(path); 
        workbook = new XSSFWorkbook(fis);
        sheet = workbook.getSheetAt(0);
    }
    public void ExelWorks()
    {
        int index = workbook.getSheetIndex("Sheet1");
        sheet = workbook.getSheetAt(index);
        int rownumber=sheet.getLastRowNum()+1;  

        for (int i=1; i<rownumber; i++ )
        {
            row = sheet.getRow(i);
            int colnumber = row.getLastCellNum();
            for (int j=0; j<colnumber; j++ )
            {
                cell = row.getCell(j);
                System.out.println(cell.getStringCellValue());
            }
        }
    }   
    public static void main(String[] args) throws IOException 
    {
        ExcelSimpleTest excelwork = new ExcelSimpleTest();
        excelwork.ExelWorks();
    }
}

For anyone who fumbled with this, here is how I got to grant the privileges, hope it helps someone

GRANT ALL ON yourdatabasename.* TO root@'%' IDENTIFIED BY
'yourRootPassword';

As noted % is a wildcard and this will allow any IP address to connect to your database. The assumption I make here is when you connect you'll have a user named root (which is the default though). Feed in the root password and you are good to go. Note that I have no single quotes (') around the user root.

for this error:

java.lang.ClassNotFoundException: com.mysql.jdbc.Driver

you need to:

Import java.sql.*;
Import com.mysql.jdbc.Driver;

even if its not used till app running.

Lets start with some data:

from pyspark.mllib.linalg import SparseVector
from pyspark.sql import Row

df1 = sqlContext.createDataFrame([
    Row(a=107831, f=SparseVector(
        5, {0: 0.0, 1: 0.0, 2: 0.0, 3: 0.0, 4: 0.0})),
    Row(a=125231, f=SparseVector(
        5, {0: 0.0, 1: 0.0, 2: 0.0047, 3: 0.0, 4: 0.0043})),
])

df2 = sqlContext.createDataFrame([
    Row(a=107831, f=SparseVector(
        5, {0: 0.0, 1: 0.0, 2: 0.0, 3: 0.0, 4: 0.0})),
    Row(a=107831, f=SparseVector(
        5, {0: 0.0, 1: 0.0, 2: 0.0, 3: 0.0, 4: 0.0})),
])

There are a few ways you can approach this problem. First of all you can unambiguously reference child table columns using parent columns:

df1.join(df2, df1['a'] == df2['a']).select(df1['f']).show(2)

##  +--------------------+
##  |                   f|
##  +--------------------+
##  |(5,[0,1,2,3,4],[0...|
##  |(5,[0,1,2,3,4],[0...|
##  +--------------------+

You can also use table aliases:

from pyspark.sql.functions import col

df1_a = df1.alias("df1_a")
df2_a = df2.alias("df2_a")

df1_a.join(df2_a, col('df1_a.a') == col('df2_a.a')).select('df1_a.f').show(2)

##  +--------------------+
##  |                   f|
##  +--------------------+
##  |(5,[0,1,2,3,4],[0...|
##  |(5,[0,1,2,3,4],[0...|
##  +--------------------+

Finally you can programmatically rename columns:

df1_r = df1.select(*(col(x).alias(x + '_df1') for x in df1.columns))
df2_r = df2.select(*(col(x).alias(x + '_df2') for x in df2.columns))

df1_r.join(df2_r, col('a_df1') == col('a_df2')).select(col('f_df1')).show(2)

## +--------------------+
## |               f_df1|
## +--------------------+
## |(5,[0,1,2,3,4],[0...|
## |(5,[0,1,2,3,4],[0...|
## +--------------------+

Here is one that works better for me (LINQPad version):

DateTime d;
DateTime.TryParseExact(
    "2010-08-20T15:00:00Z",
    @"yyyy-MM-dd\THH:mm:ss\Z",
    CultureInfo.InvariantCulture,
    DateTimeStyles.AssumeUniversal, 
    out d);
d.ToString()

produces

true

To check that the file you're trying to open actually exists, you can change directories in terminal using cd. To change to ~/Desktop/sass/css: cd ~/Desktop/sass/css. To see what files are in the directory: ls.

If you want information about either of those commands, use the man page: man cd or man ls, for example.

Google for "basic unix command line commands" or similar; that will give you numerous examples of moving around, viewing files, etc in the command line.

On Mac OS X, you can also use open to open a finder window: open . will open the current directory in finder. (open ~/Desktop/sass/css will open the ~/Desktop/sass/css).

Yes, when you invoke e.extractAll(foo), Python munges that into extractAll(e, foo).

From http://docs.python.org/tutorial/classes.html

the special thing about methods is that the object is passed as the first argument of the function. In our example, the call x.f() is exactly equivalent to MyClass.f(x). In general, calling a method with a list of n arguments is equivalent to calling the corresponding function with an argument list that is created by inserting the method’s object before the first argument.

Emphasis added.

To elaborate on previous answers about the "every x units" part, here is what I came up with:

# Draw 5 vertical lines
n = 5

# ... evenly spaced between x0 and x1
x0 = 1.0
x1 = 2.0
dx = (x1-x0)/(n-1.0)

# ... each line going from y0 to y1
y0 = 0
y1 = 10

do for [i = 0:n-1] {
    x = x0 + i*dx
    set arrow from x,y0 to x,y1 nohead linecolor "blue" # add other styling options if needed
}

TL;DR

SELECT json_agg(t) FROM t

for a JSON array of objects, and

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

for a JSON object of arrays.

List of objects

This section describes how to generate a JSON array of objects, with each row being converted to a single object. The result looks like this:

[{"a":1,"b":"value1"},{"a":2,"b":"value2"},{"a":3,"b":"value3"}]

9.3 and up

The json_agg function produces this result out of the box. It automatically figures out how to convert its input into JSON and aggregates it into an array.

SELECT json_agg(t) FROM t

There is no jsonb (introduced in 9.4) version of json_agg. You can either aggregate the rows into an array and then convert them:

SELECT to_jsonb(array_agg(t)) FROM t

or combine json_agg with a cast:

SELECT json_agg(t)::jsonb FROM t

My testing suggests that aggregating them into an array first is a little faster. I suspect that this is because the cast has to parse the entire JSON result.

9.2

9.2 does not have the json_agg or to_json functions, so you need to use the older array_to_json:

SELECT array_to_json(array_agg(t)) FROM t

You can optionally include a row_to_json call in the query:

SELECT array_to_json(array_agg(row_to_json(t))) FROM t

This converts each row to a JSON object, aggregates the JSON objects as an array, and then converts the array to a JSON array.

I wasn't able to discern any significant performance difference between the two.

Object of lists

This section describes how to generate a JSON object, with each key being a column in the table and each value being an array of the values of the column. It's the result that looks like this:

{"a":[1,2,3], "b":["value1","value2","value3"]}

9.5 and up

We can leverage the json_build_object function:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

You can also aggregate the columns, creating a single row, and then convert that into an object:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

Note that aliasing the arrays is absolutely required to ensure that the object has the desired names.

Which one is clearer is a matter of opinion. If using the json_build_object function, I highly recommend putting one key/value pair on a line to improve readability.

You could also use array_agg in place of json_agg, but my testing indicates that json_agg is slightly faster.

There is no jsonb version of the json_build_object function. You can aggregate into a single row and convert:

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Unlike the other queries for this kind of result, array_agg seems to be a little faster when using to_jsonb. I suspect this is due to overhead parsing and validating the JSON result of json_agg.

Or you can use an explicit cast:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )::jsonb
FROM t

The to_jsonb version allows you to avoid the cast and is faster, according to my testing; again, I suspect this is due to overhead of parsing and validating the result.

9.4 and 9.3

The json_build_object function was new to 9.5, so you have to aggregate and convert to an object in previous versions:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

or

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

depending on whether you want json or jsonb.

(9.3 does not have jsonb.)

9.2

In 9.2, not even to_json exists. You must use row_to_json:

SELECT row_to_json(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Documentation

Find the documentation for the JSON functions in JSON functions.

json_agg is on the aggregate functions page.

Design

If performance is important, ensure you benchmark your queries against your own schema and data, rather than trust my testing.

Whether it's a good design or not really depends on your specific application. In terms of maintainability, I don't see any particular problem. It simplifies your app code and means there's less to maintain in that portion of the app. If PG can give you exactly the result you need out of the box, the only reason I can think of to not use it would be performance considerations. Don't reinvent the wheel and all.

Nulls

Aggregate functions typically give back NULL when they operate over zero rows. If this is a possibility, you might want to use COALESCE to avoid them. A couple of examples:

SELECT COALESCE(json_agg(t), '[]'::json) FROM t

Or

SELECT to_jsonb(COALESCE(array_agg(t), ARRAY[]::t[])) FROM t

One hot encoding with pandas is very easy:

def one_hot(df, cols):
    """
    @param df pandas DataFrame
    @param cols a list of columns to encode 
    @return a DataFrame with one-hot encoding
    """
    for each in cols:
        dummies = pd.get_dummies(df[each], prefix=each, drop_first=False)
        df = pd.concat([df, dummies], axis=1)
    return df

EDIT:

Another way to one_hot using sklearn's LabelBinarizer :

from sklearn.preprocessing import LabelBinarizer 
label_binarizer = LabelBinarizer()
label_binarizer.fit(all_your_labels_list) # need to be global or remembered to use it later

def one_hot_encode(x):
    """
    One hot encode a list of sample labels. Return a one-hot encoded vector for each label.
    : x: List of sample Labels
    : return: Numpy array of one-hot encoded labels
    """
    return label_binarizer.transform(x)

This is the easiest and most efficient function to use just add as many buttons as you want to the checked = false and make the onclick event of each radio buttoncall this function. Designate a unique number to each radio button

function AdjustRadios(which) 
{
    if(which==1)
         document.getElementById("rdpPrivate").checked=false;
    else if(which==2)
         document.getElementById("rdbPublic").checked=false;
}

Resumee of Richard Fearn's answer , to make each second line gray:

jTable.setDefaultRenderer(Object.class, new DefaultTableCellRenderer()
{
    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
    {
        final Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        c.setBackground(row % 2 == 0 ? Color.LIGHT_GRAY : Color.WHITE);
        return c;
    }
});

stdin

Reads input through the console (e.g. Keyboard input). Used in C with scanf

scanf(<formatstring>,<pointer to storage> ...);

stdout

Produces output to the console. Used in C with printf

printf(<string>, <values to print> ...);

stderr

Produces 'error' output to the console. Used in C with fprintf

fprintf(stderr, <string>, <values to print> ...);

Redirection

The source for stdin can be redirected. For example, instead of coming from keyboard input, it can come from a file (echo < file.txt ), or another program ( ps | grep <userid>).

The destinations for stdout, stderr can also be redirected. For example stdout can be redirected to a file: ls . > ls-output.txt, in this case the output is written to the file ls-output.txt. Stderr can be redirected with 2>.

The parameter of exit should qualify if the execution of the program went good or bad. It's a sort of heredity from older programming languages where it's useful to know if something went wrong and what went wrong.

Exit code is

• 0 when execution went fine;
• 1, -1, whatever != 0 when some error occurred, you can use different values for different kind of errors.

If I'm correct exit codes used to be just positive numbers (I mean in UNIX) and according to range:

• 1-127 are user defined codes (so generated by calling exit(n))
• 128-255 are codes generated by termination due to different unix signals like SIGSEGV or SIGTERM

But I don't think you should care while coding on Java, it's just a bit of information. It's useful if you plan to make your programs interact with standard tools.

e can also select rows based on values of a column that are not in a list or any iterable. We will create boolean variable just like before, but now we will negate the boolean variable by placing ~ in the front.

For example

list = [1, 0]
df[df.col1.isin(list)]

I know this is an old thread, but I landed here when my row deletes were blocked by foreign key constraints. In my case, my table design permitted "NULL" values in the constrained column. In the rows to be deleted, I changed the constrained column value to "NULL" (which does not violate the Foreign Key Constraint) and then deleted all the rows.

Use DATENAME and wrap the logic in a Function, not a Stored Proc

declare @myTime as DateTime

set @myTime = GETDATE()

select @myTime

select DATENAME(day, @myTime) + SUBSTRING(UPPER(DATENAME(month, @myTime)), 0,4)

Returns "14OCT"

Try not to use any Character / String based operations if possible when working with dates. They are numerical (a float) and performance will suffer from those data type conversions.

Dig these handy conversions I have compiled over the years...

/* Common date functions */
--//This contains common date functions for MSSQL server

/*Getting Parts of a DateTime*/

You can generate the conversion table yourself by simply iterating over the $chars array of the function:

foreach($chars as $k=>$v) {
   printf("%s -> %s", $k, $v);
}

import pandas as pd 
import os 
files = os.listdir('path/to/files/directory/')
desiredFile = files[i]
filePath = 'path/to/files/directory/%s'
Ofile = filePath % desiredFile
xls_import = pd.read_csv(Ofile)

Now you can use the power of pandas DataFrames!

You just need to use Dispatcher to perform graphical operation from a thread other then UI thread. I don't think that this will affect behavior of the main form. This may help you : Accessing UI Control from BackgroundWorker Thread

Active Directory does not store the group membership on user objects. It only stores the Member list on the group. The tools show the group membership on user objects by doing queries for it.

How about:

(&(objectClass=group)(member=cn=my,ou=full,dc=domain))

(You forgot the (& ) bit in your example in the question as well).

For future readers who faced same issue with Windows Forms Application, one solution is to add these lines to your main/start up form class:

    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new MyMainForm());
    }

Then go to project properties > Application > Startup Object dropdown, should see the namespace.MyMainForm, select it, clean and build the solution. And it should work.

This should do the trick:

$("#btnAddProfile").prop('value', 'Save');       
$("#btnAddProfile").button('refresh');

Here is the answer in Razor syntax

 <table border="1" cellpadding="5">
    <thead>
       <tr>
          @foreach (System.Data.DataColumn col in Model.Columns)
          {
             <th>@col.Caption</th>
          }
       </tr>
    </thead>
    <tbody>
    @foreach(System.Data.DataRow row in Model.Rows)
    {
       <tr>
          @foreach (var cell in row.ItemArray)
          {
             <td>@cell.ToString()</td>
          }
       </tr>
    }      
    </tbody>
</table>

Please select the same in the outer select. You can't access the alias name in the same query.

At the moment there are three realy powerfull cmd.exe alternatives:

• cmder
  
• PowerCmd
• ComEmu
• Terminal for Windows 10
  

cmder is an enhancement off ConEmu and Clink

All have features like Copy & Paste, Window Resize per Mouse, Splitscreen, Tabs and a lot of other usefull features.

The Following command displays extra informations

curl -X POST http://httpbin.org/post -v > /dev/null

You can ask server to send just HEAD, instead of full response

curl -X HEAD -I http://httpbin.org/

Note: In some cases, server may send different headers for POST and HEAD. But in almost all cases headers are same.

I had faced same problem because I downloaded TestNG plugin from Eclipse. Here what I did to get the Job done :

1. After adding TestNG to your project library create one folder in your Project names as lib ( name can be anything ) :

2. Go to "C:\Program Files\Eclipse\eclipse-java-mars-R-win32-x86_64\eclipse\plugins" location and copy com.beust.jcommander_1.72.0.jar and org.testng_6.14.2.r20180216145.jar file to created folder (lib).

Note : Files are testng.jar and jcommander.jar

3. Now Launch CMD, and navigate to your project directory and then type :
   Java -cp C:\Users\User123\TestNG\lib*;C:\Users\User123\TestNG\bin org.testng.TestNG testng.xml

That's it !
Let me know if you have any more concerns.

I write below code to remove the blank value in the array string.

string[] test={"1","","2","","3"};
test= test.Except(new List<string> { string.Empty }).ToArray();

The above given ans are correct and works fine. I used in a different way.

config.yml

imports:
    - { resource: parameters.yml }
    - { resource: security.yml }
    - { resource: app.yml }
    - { resource: app_twig.yml }

app.yml

parameters:
  app.version:           1.0.1

app_twig.yml

twig:
  globals:
    version: %app.version%

Inside controller:

$application_version = $this->container->getParameter('app.version');
// Here using app.yml

Inside template/twig file:

Project version {{ version }}!
{#  Here using app_twig.yml content.  #}
{#  Because in controller we used $application_version  #}

To use controller output:

Controller:

public function indexAction() {
        $application_version = $this->container->getParameter('app.version');
        return array('app_version' => $application_version);
    }

template/twig file :

Project version {{ app_version }}

I mentioned the different for better understand.

Subtract from another date object

var d = new Date();

d.setHours(d.getHours() - 2);

• Complete reference list for Date object

What are you doing: (I am using bytes instead of in for better reading)

You start with int *ap and so on, so your (your computers) memory looks like this:

-------------- memory used by some one else --------
000: ?
001: ?
...
098: ?
099: ?
-------------- your memory  --------
100: something          <- here is *ap
101: 41                 <- here starts a[] 
102: 42
103: 43
104: 44
105: 45
106: something          <- here waits x

lets take a look waht happens when (print short cut for ...print("$d", ...)

print a[0]  -> 41   //no surprise
print a     -> 101  // because a points to the start of the array
print *a    -> 41   // again the first element of array
print a+1   -> guess? 102
print *(a+1)    -> whats behind 102? 42 (we all love this number)

and so on, so a[0] is the same as *a, a[1] = *(a+1), ....

a[n] just reads easier.

now, what happens at line 9?

ap=a[4] // we know a[4]=*(a+4) somehow *105 ==>  45 
// warning! converting int to pointer!
-------------- your memory  --------
100: 45         <- here is *ap now 45

x = *ap;   // wow ap is 45 -> where is 45 pointing to?
-------------- memory used by some one else --------
bang!      // dont touch neighbours garden

So the "warning" is not just a warning it's a severe error.

Your error indicates that the operation is being cancelled for some reason. I'd need more details to understand why. But I think the bigger issue may be that since your endpoint https://host.com/a/path is bogus, there is no real server response to report, and hence you're seeing nil.

If you hit up a valid endpoint that serves up a proper response, you should see a non-nil value for res (using the techniques Sam mentions) in the form of a NSURLHTTPResponse object with properties like statusCode, etc.

Also, just to be clear, error is of type NSError. It tells you why the network request failed. The status code of the failure on the server side is actually a part of the response.

Hope that helps answer your main question.

It seems to me you are using the wrong version...

TAP-Win32 should not be installed on the 64bit version. Download the right one and try again!

The shortest version.

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com")));

Taken the @dre010 idea, I have extended it to another function that works with any image type: PNG, JPG, JPEG or GIF and gives a unique name to the filename

The function separate image data and image type

function base64ToImage($imageData){
    $data = 'data:image/png;base64,AAAFBfj42Pj4';
    list($type, $imageData) = explode(';', $imageData);
    list(,$extension) = explode('/',$type);
    list(,$imageData)      = explode(',', $imageData);
    $fileName = uniqid().'.'.$extension;
    $imageData = base64_decode($imageData);
    file_put_contents($fileName, $imageData);
}

As explained in the different asnwers already, sys.argv contains the command line arguments that called your Python script.

However, Python comes with libraries that help you parse command line arguments very easily. Namely, the new standard argparse. Using argparse would spare you the need to write a lot of boilerplate code.

STEP3: In my front end asp.net page, I created a sql data source parameter of object type

        <tr>
        <td>
            UPLOAD DOCUMENT</td>
        <td>
            <asp:FileUpload ID="FileUpload1" runat="server" />
            <asp:Button ID="btnUpload" runat="server" Text="Upload" />
            <asp:SqlDataSource ID="sqldsFileUploadConn" runat="server" 
                ConnectionString="<%$ ConnectionStrings: %>" 
                InsertCommand="ph_SaveDocument"     
               InsertCommandType="StoredProcedure">
                <InsertParameters>
                    <asp:Parameter Name="DocBinaryForm" Type="Object" />
                </InsertParameters>

             </asp:SqlDataSource>
        </td>
        <td>
            &nbsp;</td>
    </tr>

STEP 4: In my code behind, I try to upload the FileBytes from FileUpload Control via this stored procedure call using a sql data source control

      Dim filebytes As Object
      filebytes = FileUpload1.FileBytes()
      sqldsFileUploadConn.InsertParameters("DocBinaryForm").DefaultValue = filebytes.ToString
      Dim uploadstatus As Int16 = sqldsFileUploadConn.Insert()

               ' ... code continues ... '

the way I use jsonp like below:

function jsonp(uri) {
    return new Promise(function(resolve, reject) {
        var id = '_' + Math.round(10000 * Math.random());
        var callbackName = 'jsonp_callback_' + id;
        window[callbackName] = function(data) {
            delete window[callbackName];
            var ele = document.getElementById(id);
            ele.parentNode.removeChild(ele);
            resolve(data);
        }

        var src = uri + '&callback=' + callbackName;
        var script = document.createElement('script');
        script.src = src;
        script.id = id;
        script.addEventListener('error', reject);
        (document.getElementsByTagName('head')[0] || document.body || document.documentElement).appendChild(script)
    });
}

then use 'jsonp' method like this:

jsonp('http://xxx/cors').then(function(data){
    console.log(data);
});

JavaScript XMLHttpRequest using JsonP

http://www.w3ctech.com/topic/721 (talk about the way of use Promise)

$r = array("arr1","arr2");

to echo a single array element you should write:

echo $r[0];
echo $r[1];

output would be: arr1 arr2

Currently (Laravel 5.4) the way to achieve this is:

$model = new Model();
$model->created_at = Carbon::now();
$model->save(['timestamps' => false]);

I had this same problem while hosting a web site via Parse and using a Comodo SSL cert resold by NameCheap.

You will receive two cert files inside of a zip folder: www_yourdomain_com.ca-bundle www_yourdomain_com.crt

You can only upload one file to Parse: Parse SSL Cert Input Box

In terminal combine the two files using:

cat www_yourdomain_com.crt www_yourdomain_com.ca-bundle > www_yourdomain_com_combine.crt

Then upload to Parse. This should fix the issue with Android Chrome and Firefox browsers. You can verify that it worked by testing it at https://www.sslchecker.com/sslchecker

The page will get reloaded if you don't want to use javascript

If the map is to contain only entries that are known at compile time and the keys to the map are integers, then you do not need to use a map at all.

char get_value(int key)
{
    switch (key)
    {
        case 1:
            return 'a';
        case 2:
            return 'b';
        case 3:
            return 'c';
        default:
            // Do whatever is appropriate when the key is not valid
    }
}

Also you can try this, if you want to focus on same text after error.

If you wants to show this error message in a paragraph then you can use this one:

 $(document).ready(function () {
    $("#submit").click(function () {
        if($('#selBooks').val() === '') {
            $("#Paragraph_id").text("Please select a book and then proceed.").show();
            $('#selBooks').focus();
            return false;
        }
    });
 });

To achieve a generic solution, why not do this:

$(':reset').live('click', function(){
    var $r = $(this);
    setTimeout(function(){ 
        $r.closest('form').find('.select2-offscreen').trigger('change'); 
    }, 10);
});

This way: You'll not have to make a new logic for each select2 on your application.

And, you don't have to know the default value (which, by the way, does not have to be "" or even the first option)

Finally, setting the value to :selected would not always achieve a true reset, since the current selected might well have been set programmatically on the client, whereas the default action of the form select is to return input element values to the server-sent ones.

EDIT: Alternatively, considering the deprecated status of live, we could replace the first line with this:

$('form:has(:reset)').on('click', ':reset', function(){

or better still:

$('form:has(:reset)').on('reset', function(){

PS: I personally feel that resetting on reset, as well as triggering blur and focus events attached to the original select, are some of the most conspicuous "missing" features in select2!

Aside from @Verhás István answer (which I like), I was expecting a one-liner for the question:

${project.reporting.outputDirectory} resolves to target/site in your project.

If the request if GET and we passed some query parameters then,

fro`enter code here`m flask import request
@app.route('/')
@app.route('/data')
def data():
   if request.method == 'GET':
      # Get the parameters by key
      arg1 = request.args.get('arg1')
      arg2 = request.args.get('arg2')
      # Generate the query string
      query_string="?arg1={0}&arg2={1}".format(arg1, arg2)
      return render_template("data.html", query_string=query_string)

For those who don't know how to get index_name which mentioned in Devart's answer, or key_name which mentioned in Uday Sawant's answer, you can get it like this:

SHOW INDEX FROM table_name;

This will show all indexes for the given table, then you can pick name of the index or unique key that you want to remove.

An answer after 7 years for 2018

This question was asked seven years ago, and none of answers provide practical help for the question. In the modern PHP programming you mainly use required_once only once to include your autoloader class (composer autoloader often), and it will loads all of your classes and functions (functions files need to be explicitly added to composer.json file to be available in all other files). If for any reason your class is not loadable from autoloader you use require_once to load it.

There are some occasions that we need to use require. For example, if you have a really big array definition and you don't want to add this to your class definition source code you can:

 <?php
// arr.php
return ['x'=>'y'];

 <?php
//main.php
$arr= require 'arry.php'

If the file that you intend to include contains something executable or declares some variables you almost always need to use require, because if you use require_once apart from the first place your code will not be executed and/or your variables will not initiate silently, causing bugs that are absolutely hard to pinpoint.

There is no practical use case for include and include_once really.

Also,

var url = $(this).attr("href");
var part = url.substring(url.lastIndexOf('/') + 1);

Please update new user repository URL

 git remote set-url origin https://[email protected]/repository.git

I tried using below commands, it's not working:

git config user.email "[email protected]"
git config user.name  "user"

OR

git config --global user.email "[email protected]"
git config --global user.name "user"

A simpler way to get the selected value from a ComboBox control is:

Private Sub myComboBox_Change()
  msgbox "You selected: " + myComboBox.SelText
End Sub

>>> import subprocess

There is a bug in using of the subprocess.PIPE. For the huge output use this:

import subprocess
import tempfile

with tempfile.TemporaryFile() as tempf:
    proc = subprocess.Popen(['echo', 'a', 'b'], stdout=tempf)
    proc.wait()
    tempf.seek(0)
    print tempf.read()

Simple solution

setcookie("NAME", "VALUE", time()+3600, '/', EXAMPLE.COM);

Setcookie's 5th parameter determines the (sub)domains that the cookie is available to. Setting it to (EXAMPLE.COM) makes it available to any subdomain (eg: SUBDOMAIN.EXAMPLE.COM )

Reference: http://php.net/manual/en/function.setcookie.php

Any time you do calculations with doubles, this can happen. This code would give you 877.85:

double answer = Math.round(dCommission * 100000) / 100000.0;

Try this, it works for both node and the browser.

isNode = (typeof exports !== 'undefined') &&
(typeof module !== 'undefined') &&
(typeof module.exports !== 'undefined') &&
(typeof navigator === 'undefined' || typeof navigator.appName === 'undefined') ? true : false,
asyncIt = (isNode ? function (func) {
  process.nextTick(function () {
    func();
  });
} : function (func) {
  setTimeout(func, 5);
});

$ sbt sbtVersion

This prints the sbt version used in your current project, or if it is a multi-module project for each module.

$ sbt 'inspect sbtVersion'
[info] Set current project to jacek (in build file:/Users/jacek/)
[info] Setting: java.lang.String = 0.13.1
[info] Description:
[info]  Provides the version of sbt.  This setting should be not be modified.
[info] Provided by:
[info]  */*:sbtVersion
[info] Defined at:
[info]  (sbt.Defaults) Defaults.scala:68
[info] Delegates:
[info]  *:sbtVersion
[info]  {.}/*:sbtVersion
[info]  */*:sbtVersion
[info] Related:
[info]  */*:sbtVersion

You may also want to use sbt about that (copying Mark Harrah's comment):

The about command was added recently to try to succinctly print the most relevant information, including the sbt version.

string myHTML = "some words " + Environment.NewLine + "more words");

Try this:

x = "{{ Hello }} {0}"

Yes. Although I use the following code.

.carousel.fade
{
    opacity: 1;

    .item
    {
        -moz-transition: opacity ease-in-out .7s;
        -o-transition: opacity ease-in-out .7s;
        -webkit-transition: opacity ease-in-out .7s;
        transition: opacity ease-in-out .7s;
        left: 0 !important;
        opacity: 0;
        top:0;
        position:absolute;
        width: 100%;
        display:block !important;
        z-index:1;
        &:first-child{
            top:auto;
            position:relative;
        }

        &.active
        {
            opacity: 1;
            -moz-transition: opacity ease-in-out .7s;
            -o-transition: opacity ease-in-out .7s;
            -webkit-transition: opacity ease-in-out .7s;
            transition: opacity ease-in-out .7s;
            z-index:2;
        }
    }
}

Then change the class on the carousel from "carousel slide" to "carousel fade". This works in safari, chrome, firefox, and IE 10. It will correctly downgrade in IE 9, however, the nice face effect doesn't happen.

Edit: Since this answer has gotten so popular I've added the following which rewritten as pure CSS instead of the above which was LESS:

.carousel.fade {
  opacity: 1;
}
.carousel.fade .item {
  -moz-transition: opacity ease-in-out .7s;
  -o-transition: opacity ease-in-out .7s;
  -webkit-transition: opacity ease-in-out .7s;
  transition: opacity ease-in-out .7s;
  left: 0 !important;
  opacity: 0;
  top:0;
  position:absolute;
  width: 100%;
  display:block !important;
  z-index:1;
}
.carousel.fade .item:first-child {
  top:auto;
  position:relative;
}
.carousel.fade .item.active {
  opacity: 1;
  -moz-transition: opacity ease-in-out .7s;
  -o-transition: opacity ease-in-out .7s;
  -webkit-transition: opacity ease-in-out .7s;
  transition: opacity ease-in-out .7s;
  z-index:2;
}

I know its late but I think you can try like this

$("#multipledpdwn").on("select2:select select2:unselect", function (e) {

    //this returns all the selected item
    var items= $(this).val();       

    //Gets the last selected item
    var lastSelectedItem = e.params.data.id;

})

Hope it may help some one in future.

here are two samples: http://jsfiddle.net/H5q5h/1/

one uses float:left and a wrapper with overflow:hidden. the wrapper ensures the sibling of the wrapper starts below the wrapper.

the 2nd one uses the more recent display:inline-block and wrapper can be disregarded. but this is not generally supported by older browsers so tread lightly on this one. also, any white space between the items will cause an unnecessary "margin-like" white space on the left and right of the item divs.

"%f" is the (or at least one) correct format for a double. There is no format for a float, because if you attempt to pass a float to printf, it'll be promoted to double before printf receives it¹. "%lf" is also acceptable under the current standard -- the l is specified as having no effect if followed by the f conversion specifier (among others).

Note that this is one place that printf format strings differ substantially from scanf (and fscanf, etc.) format strings. For output, you're passing a value, which will be promoted from float to double when passed as a variadic parameter. For input you're passing a pointer, which is not promoted, so you have to tell scanf whether you want to read a float or a double, so for scanf, %f means you want to read a float and %lf means you want to read a double (and, for what it's worth, for a long double, you use %Lf for either printf or scanf).

_{1. C99, §6.5.2.2/6: "If the expression that denotes the called function has a type that does not include a prototype, the integer promotions are performed on each argument, and arguments that have type float are promoted to double. These are called the default argument promotions." In C++ the wording is somewhat different (e.g., it doesn't use the word "prototype") but the effect is the same: all the variadic parameters undergo default promotions before they're received by the function.}

I figured it out already:

as.data.frame.matrix(mytable) 

does what I need -- apparently, the table needs to somehow be converted to a matrix in order to be appropriately translated into a data frame. I found more details on this as.data.frame.matrix() function for contingency tables at the Computational Ecology blog.

try something like this FIDDLE

    try
      {
        navigator.device.capture.captureImage(function(mediaFiles) {
        console.log("works");
         });
      }

    catch(err)
      {
        alert('hi');
        $("#captureImage").prop('checked', false);

      }

Just wrap all that inside a ScrollView:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
    <!-- Here you put the rest of your current view-->
</ScrollView>

As David Hedlund said, ScrollView can contain just one item... so if you had something like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
    <!-- bla bla bla-->
</LinearLayout>

You must change it to:

<?xml version="1.0" encoding="utf-8"?>
<ScrollView
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">
    <LinearLayout
      android:layout_width="fill_parent"
      android:layout_height="fill_parent">
        <!-- bla bla bla-->
    </LinearLayout>
</ScrollView>

I use ? and ?, but they might not work for you. I use alt 11551 for the first one and 11550 for the second one. You can always copy paste them if the ascii isnt the same for your system.

What about

import operator

auths = Author.objects.order_by('-score')[:30]
ordered = sorted(auths, key=operator.attrgetter('last_name'))

In Django 1.4 and newer you can order by providing multiple fields.
Reference: https://docs.djangoproject.com/en/dev/ref/models/querysets/#order-by

order_by(*fields)

By default, results returned by a QuerySet are ordered by the ordering tuple given by the ordering option in the model’s Meta. You can override this on a per-QuerySet basis by using the order_by method.

Example:

ordered_authors = Author.objects.order_by('-score', 'last_name')[:30]

The result above will be ordered by score descending, then by last_name ascending. The negative sign in front of "-score" indicates descending order. Ascending order is implied.

You can somehow reproduce the behavior of "OR" using & and :not.

SomeElement.SomeClass [data-statement="things are getting more complex"]  :not(:not(A):not(B))     {
    /* things aren't so complex for A or B */
}

z-index only works within a particular context i.e. relative, fixed or absolute position.

z-index for a relative div has nothing to do with the z-index of an absolutely or fixed div.

EDIT This is an incomplete answer. This answer provides false information. Please review @Dansingerman's comment and example below.

If you are using microsoft query, you can add "?" to your query...

select name from user where id= ?

that will popup a small window asking for the cell/data/etc when you go back to excel.

In the popup window, you can also select "always use this cell as a parameter" eliminating the need to define that cell every time you refresh your data. This is the easiest option.

The following was all done in cygwin on a Windows XP box.

This will get your IP address. Note that there are backquotes around the hostname command, not single quotes.

ping -n 1 `hostname` | grep "Reply from " | cut -f 3 -d " " | cut -f 1 -d ":"

This will get your subnet.

ping -n 1 `hostname` | grep "Reply from " | cut -f 3 -d " " | cut -f "1 2 3" -d "."

The following will list all hosts on your local network (put it into a script called "netmap"). I had taken the subnet line above and put it into an executable called "getsubnet", which I then called from the following script.

MINADDR=0
MAXADDR=255
SUBNET=`getsubnet`

hostcnt=0

echo Pinging all addresses in ${SUBNET}.${MINADDR}-${MAXADDR}

for i in `seq $MINADDR $MAXADDR`; do
addr=${SUBNET}.$i
ping -n 1 -w 0 $addr > /dev/null

if [ $? -ne 1 ]    
then    
echo $addr UP    
hostcnt=$((hostcnt+1))    
fi

done

echo Found $hostcnt hosts on subnet ${SUBNET}.${MINADDR}-${MAXADDR}

The problem appears to be that the global symbol clear is already in use and your function doesn't succeed in overriding it. If you change that name to something else (I used blah), it works just fine:

Live: Version using clear which fails | Version using blah which works

<html>
<head>
    <title>lala</title>
</head>
<body>
    <h1 onmouseover="go('The dog is in its shed')" onmouseout="blah()">lalala</h1>
    <div id="goy"></div>
    <script type="text/javascript">
    function go(what) {
        document.getElementById("goy").innerHTML = what;
    }
    function blah() {
        document.getElementById("goy").innerHTML = "";
    }
    </script>
</body>
</html>

This is a great illustration of the fundamental principal: Avoid global variables wherever possible. The global namespace in browsers is incredibly crowded, and when conflicts occur, you get weird bugs like this.

A corollary to that is to not use old-style onxyz=... attributes to hook up event handlers, because they require globals. Instead, at least use code to hook things up: Live Copy

<html>
<head>
    <title>lala</title>
</head>
<body>
    <h1 id="the-header">lalala</h1>
    <div id="goy"></div>
    <script type="text/javascript">
      // Scoping function makes the declarations within
      // it *not* globals
      (function(){
        var header = document.getElementById("the-header");
        header.onmouseover = function() {
          go('The dog is in its shed');
        };
        header.onmouseout = clear;

        function go(what) {
          document.getElementById("goy").innerHTML = what;
        }
        function clear() {
          document.getElementById("goy").innerHTML = "";
        }
      })();
    </script>
</body>
</html>

...and even better, use DOM2's addEventListener (or attachEvent on IE8 and earlier) so you can have multiple handlers for an event on an element.

In addition to Settings -> Editor -> Use soft wraps in editor I recommend Use soft wraps in console and Use custom soft wraps indent with a setting of 4 to make the wraps indented to match the line they started on.

When you use routerLink like this, then you need to pass the value of the route it should go to. But when you use routerLink with the property binding syntax, like this: [routerLink], then it should be assigned a name of the property the value of which will be the route it should navigate the user to.

So to fix your issue, replace this routerLink="['/about']" with routerLink="/about" in your HTML.

There were other places where you used property binding syntax when it wasn't really required. I've fixed it and you can simply use the template syntax below:

<nav class="main-nav>
  <ul 
    class="main-nav__list" 
    ng-sticky 
    addClass="main-sticky-link" 
    [ngClass]="ref.click ? 'Navbar__ToggleShow' : ''">
    <li class="main-nav__item" routerLinkActive="active">
      <a class="main-nav__link" routerLink="/">Home</a>
    </li>
    <li class="main-nav__item" routerLinkActive="active"> 
      <a class="main-nav__link" routerLink="/about">About us</a>
    </li>
  </ul>
</nav>

It also needs to know where exactly should it load the template for the Component corresponding to the route it has reached. So for that, don't forget to add a <router-outlet></router-outlet>, either in your template provided above or in a parent component.

There's another issue with your AppRoutingModule. You need to export the RouterModule from there so that it is available to your AppModule when it imports it. To fix that, export it from your AppRoutingModule by adding it to the exports array.

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { MainLayoutComponent } from './layout/main-layout/main-layout.component';
import { AboutComponent } from './components/about/about.component';
import { WhatwedoComponent } from './components/whatwedo/whatwedo.component';
import { FooterComponent } from './components/footer/footer.component';
import { ProjectsComponent } from './components/projects/projects.component';
const routes: Routes = [
  { path: 'about', component: AboutComponent },
  { path: 'what', component: WhatwedoComponent },
  { path: 'contacts', component: FooterComponent },
  { path: 'projects', component: ProjectsComponent},
];

@NgModule({
  imports: [
    CommonModule,
    RouterModule.forRoot(routes),
  ],
  exports: [RouterModule],
  declarations: []
})
export class AppRoutingModule { }

Here is more functional example with some ES6 features:

'use strict';

const React = require('react');

function renderArticles(articles) {
    if (articles.length > 0) {      
        return articles.map((article, index) => (
            <Article key={index} article={article} />
        ));
    }
    else return [];
}

const Article = ({article}) => {

There are certain scenarios in which you can follow the steps suggested in the other answers, verify that Execution Policy is set correctly, and still have your scripts fail. If this happens to you, you are probably on a 64-bit machine with both 32-bit and 64-bit versions of PowerShell, and the failure is happening on the version that doesn't have Execution Policy set. The setting does not apply to both versions, so you have to explicitly set it twice.

Look in your Windows directory for System32 and SysWOW64.

Repeat these steps for each directory:

1. Navigate to WindowsPowerShell\v1.0 and launch powershell.exe

2. Check the current setting for ExecutionPolicy:

   Get-ExecutionPolicy -List

3. Set the ExecutionPolicy for the level and scope you want, for example:

   Set-ExecutionPolicy -Scope LocalMachine Unrestricted

Note that you may need to run PowerShell as administrator depending on the scope you are trying to set the policy for.

You can read a lot more here: Running Windows PowerShell Scripts

This is a problem with your web server sending out an HTTP header that does not match the one you define. For instructions on how to make the server send the correct headers, see this page.

Otherwise, you can also use PHP to modify the headers, but this has to be done before outputting any text using this code:

header('Content-Type: text/html; charset=utf-8');

More information on how to send out headers using PHP can be found in the documentation for the header function.

Convert binary file to base64 & vice versa. Prove in python 3.5.2

import base64

read_file = open('/tmp/newgalax.png', 'rb')
data = read_file.read()

b64 = base64.b64encode(data)

print (b64)

# Save file
decode_b64 = base64.b64decode(b64)
out_file = open('/tmp/out_newgalax.png', 'wb')
out_file.write(decode_b64)

# Test in python 3.5.2

While I enjoy using dplyr for interactive use, I find it extraordinarily tricky to do this using dplyr because you have to go through hoops to use lazyeval::interp(), setNames, etc. workarounds.

Here is a simpler version using base R, in which it seems more intuitive, to me at least, to put the loop inside the function, and which extends @MrFlicks's solution.

multipetal <- function(df, n) {
   for (i in 1:n){
      varname <- paste("petal", i , sep=".")
      df[[varname]] <- with(df, Petal.Width * i)
   }
   df
}
multipetal(iris, 3) 

It's hard to answer you without the HTML, but in general you can put:

style="width: 50%;"

On either the table cell, or place a div inside the table cell, and put the style on that.

But one problem is "50% of what?" It's 50% of the parent element which may not be what you want.

Post a copy of your HTML and maybe you'll get a better answer.

On the one hand, throwing exceptions is inherently expensive, because the stack has to be unwound etc.
On the other hand, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.

BTW: The correct way to do this is to use TryGetValue

obj item;
if(!dict.TryGetValue(name, out item))
    return null;
return item;

This accesses the dictionary only once instead of twice.
If you really want to just return null if the key doesn't exist, the above code can be simplified further:

obj item;
dict.TryGetValue(name, out item);
return item;

This works, because TryGetValue sets item to null if no key with name exists.

A problem that you get when you allow constructors in interfaces comes from the possibility to implement several interfaces at the same time. When a class implements several interfaces that define different constructors, the class would have to implement several constructors, each one satisfying only one interface, but not the others. It will be impossible to construct an object that calls each of these constructors.

Or in code:

interface Named { Named(String name); }
interface HasList { HasList(List list); }

class A implements Named, HasList {

  /** implements Named constructor.
   * This constructor should not be used from outside, 
   * because List parameter is missing
   */
  public A(String name)  { 
    ...
  }

  /** implements HasList constructor.
   * This constructor should not be used from outside, 
   * because String parameter is missing
   */
  public A(List list) {
    ...
  }

  /** This is the constructor that we would actually 
   * need to satisfy both interfaces at the same time
   */ 
  public A(String name, List list) {
    this(name);
    // the next line is illegal; you can only call one other super constructor
    this(list); 
  }
}

As it turns out the answer is always simple.

Here is a small sample module with a simple way to show it in a main definition:

def five(enterAnumber,sumation):
    global helper
    helper  = enterAnumber + sumation

def isTheNumber():
    return helper

Here is how to show it in a main definition:

import TestPy

def main():
    atest  = TestPy
    atest.five(5,8)
    print(atest.isTheNumber())

if __name__ == '__main__':
    main()

This simple code works just like that, and it will execute. I hope it helps.

You can put the condition after the WHEN clause, like so:

SELECT
  CASE
    WHEN PAT_ENT.SCR_DT is not null and PAT_ENTRY.ELIGIBILITY is null THEN 'Favor'
    WHEN PAT_ENT.SCR_DT is not null and PAT_ENTRY.EL = 'No' THEN 'Error'
    WHEN PAT_ENTRY.EL = 'Yes' and ISNULL(DS.DES, 'OFF') = 'OFF' THEN 'Active'
    WHEN DS.DES = 'N' THEN 'Early Term'
    WHEN DS.DES = 'Y' THEN 'Complete'
  END
FROM
  ....

Of course, the argument could be made that complex rules like this belong in your business logic layer, not in a stored procedure in the database...

Combining all the answers I found this to be the best

Heres the code that creates a Dialog which allows the user of your application to change the Look And Feel based on the user's systems. Alternatively, if you can store the wanted Look And Feel's on your application, then they could be "portable", which is the desired result.

   public void changeLookAndFeel() {

        List<String> lookAndFeelsDisplay = new ArrayList<>();
        List<String> lookAndFeelsRealNames = new ArrayList<>();

        for (LookAndFeelInfo each : UIManager.getInstalledLookAndFeels()) {
            lookAndFeelsDisplay.add(each.getName());
            lookAndFeelsRealNames.add(each.getClassName());
        }

        String changeLook = (String) JOptionPane.showInputDialog(this, "Choose Look and Feel Here:", "Select Look and Feel", JOptionPane.QUESTION_MESSAGE, null, lookAndFeelsDisplay.toArray(), null);

        if (changeLook != null) {
            for (int i = 0; i < lookAndFeelsDisplay.size(); i++) {
                if (changeLook.equals(lookAndFeelsDisplay.get(i))) {
                    try {
                        UIManager.setLookAndFeel(lookAndFeelsRealNames.get(i));
                        break;
                    }
                    catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
                        err.println(ex);
                        ex.printStackTrace(System.err);
                    }
                }
            }
        }
    }

I was trying to send notification using the fcm api "https://fcm.googleapis.com/fcm/send" from postman. Server key was ok and token was pasted fine but was still getting error "MismatchSenderId".

Then introduced the follwoing dependency in the gradle file on android side.

implementation platform('com.google.firebase:firebase-bom:25.12.0') 

and it started receiving notifications on the device

You could use stringstream.

#include <sstream>

// ...
std::string number;
std::stringstream strstream;
strstream << 1L;
strstream >> number;

There is usually some proprietary C functions in the standard library for your compiler that does it too. I prefer the more "portable" variants though.

The C way to do it would be with sprintf, but that is not very secure. In some libraries there is new versions like sprintf_s which protects against buffer overruns.

The Guava Library has Strings.padStart that does exactly what you want, along with many other useful utilities.

In Python (question was originally tagged Python) you need to import the time module

import time
time.sleep(1)

or

from time import sleep
sleep(1)

For shell script is is just

sleep 1

Which executes the sleep command. eg. /bin/sleep

You can convert the time using the following code.

TimeSpan _time = TimeSpan.Parse("07:35");

But if you want to get the current time of the day you can use the following code:

TimeSpan _CurrentTime = DateTime.Now.TimeOfDay;

The result will be:

03:54:35.7763461

With a object cantain the Hours, Minutes, Seconds, Ticks and etc.

There is no difference between them.

If you don't specify a value for any of the half-dozen properties that background is a shorthand for, then it is set to its default value. none and transparent are the defaults.

One explicitly sets the background-image to none and implicitly sets the background-color to transparent. The other is the other way around.

Splice is the best to remove element from specific index. The given example is tested on console.

card = [1, 2, 3, 4];
card.splice(1,1);  // [2]
card   // (3) [1, 3, 4]
splice(startingIndex, totalNumberOfElements)

startingIndex start from 0.

I've ran across this problem recently while trying to retrieve a null decimal from a DataTable object from db and I haven't seen this answer here. I find this easier and shorter:

var value = rdrSelect.Field<decimal?>("ColumnName") ?? 0;

This was useful in my case since i didn't have a nullable decimal in the model, but needed a quick check against one. If the db value happens to be null, it'll just assign the default value.

FOR Swift 5+

let searchBarButtonItem = UIBarButtonItem(image: UIImage(named: "searchIcon"), style: .plain, target: self, action: #selector(onSearchButtonClicked))
        self.navigationItem.rightBarButtonItem  = searchBarButtonItem

@objc func onSearchButtonClicked(_ sender: Any){
    print("SearchButtonClicked")
}

It's worth noting that the SMTP module supports the context manager so there is no need to manually call quit(), this will guarantee it is always called even if there is an exception.

    with smtplib.SMTP_SSL('smtp.gmail.com', 465) as server:
        server.ehlo()
        server.login(user, password)
        server.sendmail(from, to, body)

localhost and 127.0.0.1 are both ways of saying 'the current machine'. So localhost on your PC is the PC and localhost on the android is the phone. Since your phone isn't running a webserver of course it will refuse the connection.

You need to get the IP address of your machine (use ipconfig on windows to find out) and use that instead of 127.0.0.1. This may still not working depending on how your network/firewalls are set up. But that is a completely different topic.

My problem was in wrong classes. I used custom .xib for my custom view. Correctly it has to be set like here:

1. View shouldn't have a class
2. Class which is used with the .xib is set in File's Owner tab

3. Outlets are connected to File's Owner and not to the View.

   

There can be a problem with "\00a0" in pseudo-elements because it takes the text-decoration of its defining element, so that, for example, if the defining element is underlined, then the white space of the pseudo-element is also underlined.

The easiest way to deal with this is to define the opacity of the pseudo-element to be zero, eg:

element:before{
  content: "_";
  opacity: 0;
}

If you already have the figure object use:

f.set_figheight(15)
f.set_figwidth(15)

But if you use the .subplots() command (as in the examples you're showing) to create a new figure you can also use:

f, axs = plt.subplots(2,2,figsize=(15,15))

Simple! The folder named .. is the parent folder, so you can make the path to the file you need as such

var foobar = require('../config/dev/foobar.json');

If you needed to go up two levels, you would write ../../ etc

Issue #2 now can be solved using BroadcastAPI.

At the moment it's only available in Chrome, Firefox, and Opera.

var bc = new BroadcastChannel('test_channel');

bc.onmessage = function (ev) { 
    if(ev.data && ev.data.url===window.location.href){
       alert('You cannot open the same page in 2 tabs');
    }
}

bc.postMessage(window.location.href);

The title "WPF Label Foreground Color" is very simple (exactly what I was looking for) but the OP's code is so cluttered it's easy to miss how simple it can be to set text foreground color on two different labels:

<StackPanel>
    <Label Foreground="Red">Red text</Label>
    <Label Foreground="Blue">Blue text</Label>
</StackPanel>

In summary, No, there was nothing wrong with your snippet.

First install Ubuntu's python-lxml package and its dependencies:

sudo apt-get install python-lxml

Then use pip to upgrade to the latest version of lxml for Python:

pip install lxml

You're trying to do &(2), &(4) which won't work

#romtest {
  .detailed {
    th {
      &:nth-child(2) {//your styles here}
      &:nth-child(4) {//your styles here}
      &:nth-child(6) {//your styles here}
      }
  }
}

create shape.xml in drawable folder

like shape.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
  <stroke android:width="2dp"
    android:color="#FFFFFF"/>
  <gradient 
    android:angle="225"
    android:startColor="#DD2ECCFA"
    android:endColor="#DD000000"/>
<corners
    android:bottomLeftRadius="7dp"
    android:bottomRightRadius="7dp"
    android:topLeftRadius="7dp"
   android:topRightRadius="7dp" />
</shape>

and in myactivity.xml

you can use

<Button
    android:id="@+id/btn_Shap"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    android:text="@string/Shape"
    android:background="@drawable/shape"/>

You can give this a try using recursion. This will download them in sync, one after another until it completes downloading the whole list.

var queue = ['url/links/go/here'];

ProcessScripts(function() { // All done do what ever you want

}, 0);

function ProcessScripts(cb, index) {
    getScript(queue[index], function() {
        index++;
        if (index === queue.length) { // Reached the end
            cb();
        } else {
            return ProcessScripts(cb, index);
        }
    });
}

function getScript(script, callback) {
    $.getScript(script, function() {
        callback();
    });
}

A real problem often exists because any variables set inside will not be exported when that batch file finishes. So its not possible to export, which caused us issues. As a result, I just set the registry to ALWAYS used delayed expansion (I don't know why it's not the default, could be speed or legacy compatibility issue.)

I was having the same error, but i fixed it after reinstalling the HAXM. This problem is caused because of the virtual device not starting properly. If your device keep showing on screen "Android" or the screen is black, it have not started yet, you have to wait more for it to start properly, then it shall run. If it is too slow, maybe you should find a way to accelerate the Android Virtual Device (AVD). The Intel computers have the HAXM (hardware-accelerated-execution-manager).

In my computer was not starting because of the HAXM not working, I fixed it by reinstalling the HAXM, downloading it from the intel website: "https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager"

Then i set the HAXM max memory to 1536MB in the installation, for not having the problem of this other post, that you maybe have and i was having too: "HAXM configuration in android studio"

After all done, it worked fine.

You can also disable a specific rule/rules (rather than all) by specifying them in the enable (open) and disable (close) blocks:

/* eslint-disable no-alert, no-console */

alert('foo');
console.log('bar');

/* eslint-enable no-alert */

via @goofballMagic's link above: http://eslint.org/docs/user-guide/configuring.html#configuring-rules

Use the built in date_sub and date_add functions to math with dates. (See http://php.net/manual/en/datetime.sub.php)

Similar to Sazzad's answer, but in procedural style PHP,

$date = date_create('2008-12-02');
date_sub($date, date_interval_create_from_date_string('5 days'));
echo date_format($date, 'Y-m-d'); //outputs 2008-11-27

You can use the key parameter to list.sort():

my_list.sort(key=lambda x: x[1])

or, slightly faster,

my_list.sort(key=operator.itemgetter(1))

(As with any module, you'll need to import operator to be able to use it.)

I've personally never seen .cc in any project that I've worked on, but in all technicality the compiler won't care.

Who will care is the developers working on your source, so my rule of thumb is to go with what your team is comfortable with. If your "team" is the open source community, go with something very common, of which .cpp seems to be the favourite.

You can get the file name, but you can also get the full path, depending what you place between the '%~' and the '0'. Take your pick from

d -- drive
p -- path
n -- file name
x -- extension
f -- full path

E.g., from inside c:\tmp\foo.bat, %~nx0 gives you "foo.bat", whilst %~dpnx0 gives "c:\tmp\foo.bat". Note the pieces are always assembled in canonical order, so if you get cute and try %~xnpd0, you still get "c:\tmp\foo.bat"

The issue is that you are serializing your bean with a custom Gson object while the application is attempting to deserialize your JSON with a Jackson ObjectMapper (within MappingJackson2HttpMessageConverter).

If you open up your server logs, you should see something like

Exception in thread "main" com.fasterxml.jackson.databind.exc.InvalidFormatException: Can not construct instance of java.util.Date from String value '2013-34-10-10:34:31': not a valid representation (error: Failed to parse Date value '2013-34-10-10:34:31': Can not parse date "2013-34-10-10:34:31": not compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "EEE, dd MMM yyyy HH:mm:ss zzz", "yyyy-MM-dd"))
 at [Source: java.io.StringReader@baea1ed; line: 1, column: 20] (through reference chain: com.spring.Bean["publicationDate"])

among other stack traces.

One solution is to set your Gson date format to one of the above (in the stacktrace).

The alternative is to register your own MappingJackson2HttpMessageConverter by configuring your own ObjectMapper to have the same date format as your Gson.

Here is a fast native head command that gives you the first 9 lines in DOS.

findstr /n "." myfile.txt | findstr "^.:"

The first 2 characters on each line will be the line number.

This is how you can do it from DB2 client.

1. Open the Command Editor and Run the select Query in the Commands Tab.

2. Open the corresponding Query Results Tab

3. Then from Menu --> Selected --> Export

cout << text << " " << i << endl;

Why use GROUP BY at all?

SELECT player_name, player_salary, player_salary*1.1 AS NewSalary
FROM players
ORDER BY player_salary DESC

From the Transitioning to ARC Release Notes (the example in the section on property attributes).

// The following declaration is a synonym for: @property(retain) MyClass *myObject;

@property(strong) MyClass *myObject;

So strong is the same as retain in a property declaration.

For ARC projects I would use strong instead of retain, I would use assign for C primitive properties and weak for weak references to Objective-C objects.

Just include windows.h instead of stdfax or create a clean project without template.

site-packages is the target directory of manually built Python packages. When you build and install Python packages from source (using distutils, probably by executing python setup.py install), you will find the installed modules in site-packages by default.

There are standard locations:

• Unix (pure)¹: prefix/lib/pythonX.Y/site-packages
• Unix (non-pure): exec-prefix/lib/pythonX.Y/site-packages
• Windows: prefix\Lib\site-packages

¹ Pure means that the module uses only Python code. Non-pure can contain C/C++ code as well.

site-packages is by default part of the Python search path, so modules installed there can be imported easily afterwards.

For List:

All SwiftUI's Lists are backed by a UITableViewin iOS. so you need to change the background color of the tableView. But since Color and UIColor values are slightly different, you can get rid of the UIColor.

struct ContentView : View {
    init(){
        UITableView.appearance().backgroundColor = .clear
    }
    
    var body: some View {
        List {
            Section(header: Text("First Section")) {
                Text("First Cell")
            }
            Section(header: Text("Second Section")) {
                Text("First Cell")
            }
        }
        .background(Color.yellow)
    }
}

Now you can use Any background (including all Colors) you want

Also First look at this result:

As you can see, you can set the color of each element in the View hierarchy like this:

struct ContentView: View {
    
    init(){
        UINavigationBar.appearance().backgroundColor = .green 
        //For other NavigationBar changes, look here:(https://stackoverflow.com/a/57509555/5623035)
    }

    var body: some View {
        ZStack {
            Color.yellow
            NavigationView {
                ZStack {
                    Color.blue
                    Text("Some text")
                }
            }.background(Color.red)
        }
    }
}

And the first one is window:

window.backgroundColor = .magenta

The very common issue is we can not remove the background color of SwiftUI's HostingViewController (yet), so we can't see some of the views like navigationView through the views hierarchy. You should wait for the API or try to fake those views (not recommended).

ps -ef

will list all your currently running processes

| grep tomcat

will pass the output to grep and look for instances of tomcat. Since the grep is a process itself, it is returned from your command. However, your output shows no processes of Tomcat running.

If you want to find the total number of non-empty lines, you could use AWK:

git ls-files | xargs cat | awk '/\S/{x++} END{print "Total number of non-empty lines:", x}'

This uses regex to count the lines containing a non-whitespace character.

The output can be redirected to a text file and then read it back.

import os
import tempfile

def execute_to_file(command):
    """
    This function execute the command

    temp_file = tempfile.NamedTemporaryFile(delete=False)
    temp_file.close()
    path = temp_file.name
    command = command + " > " + path
    proc = subprocess.run(command, shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, universal_newlines=True)
    if proc.stderr:
