you can use a Scanner to read from input :

Scanner scanner = new Scanner(System.in); 
char c = scanner.next().charAt(0); //charAt() method returns the character at the specified index in a string. The index of the first character is 0, the second character is 1, and so on.

var fs = require("fs");

function readFileLineByLine(filename, processline) {
    var stream = fs.createReadStream(filename);
    var s = "";
    stream.on("data", function(data) {
        s += data.toString('utf8');
        var lines = s.split("\n");
        for (var i = 0; i < lines.length - 1; i++)
            processline(lines[i]);
        s = lines[lines.length - 1];
    });

    stream.on("end",function() {
        var lines = s.split("\n");
        for (var i = 0; i < lines.length; i++)
            processline(lines[i]);
    });
}

var linenumber = 0;
readFileLineByLine(filename, function(line) {
    console.log(++linenumber + " -- " + line);
});

ls -l --block-size=M 

will give you a long format listing (needed to actually see the file size) and round file sizes up to the nearest MiB. If you want MB (10^6 bytes) rather than MiB (2^20 bytes) units, use --block-size=MB instead.

Or

ls -lah 

-h When used with the -l option, use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte and Petabyte in order to reduce the number of digits to three or less using base 2 for sizes.

It's because you're missing position:relative; on #contentframe

<div id="contentframe" style="position:relative; top: 160px; left: 0px;">

position:absolute; positions itself against the closest ancestor that has a position that is not static. Since the default is static that is what was causing your issue.

If you want to hide the cursor in the entire webpage, using body will not work unless it covers the entire visible page, which is not always the case. To make sure the cursor is hidden everywhere in the page, use:

document.documentElement.style.cursor = 'none';

To reenable it:

document.documentElement.style.cursor = 'auto';

The analogue with static CSS notation is in the answer by Pavel Salaquarda (in essence: html * {cursor:none})

Here's a small example to demonstrate this (which only applied to DataFrames, not Series, until Pandas 0.19 where it applies to both):

In [1]: df1 = pd.DataFrame([[1, 2], [3, 4]])

In [2]: df2 = pd.DataFrame([[3, 4], [1, 2]], index=[1, 0])

In [3]: df1 == df2
Exception: Can only compare identically-labeled DataFrame objects

One solution is to sort the index first (Note: some functions require sorted indexes):

In [4]: df2.sort_index(inplace=True)

In [5]: df1 == df2
Out[5]: 
      0     1
0  True  True
1  True  True

Note: == is also sensitive to the order of columns, so you may have to use sort_index(axis=1):

In [11]: df1.sort_index().sort_index(axis=1) == df2.sort_index().sort_index(axis=1)
Out[11]: 
      0     1
0  True  True
1  True  True

Note: This can still raise (if the index/columns aren't identically labelled after sorting).

You need to use brackets when using the fileExists step in an if condition or assign the returned value to a variable

Using variable:

def exists = fileExists 'file'

if (exists) {
    echo 'Yes'
} else {
    echo 'No'
}

Using brackets:

if (fileExists('file')) {
    echo 'Yes'
} else {
    echo 'No'
}

The best practice is using File.separator in the paths.

#button {
    line-height: 12px;
    width: 18px;
    font-size: 8pt;
    font-family: tahoma;
    margin-top: 1px;
    margin-right: 2px;
    position: absolute;
    top: 0;
    right: 0;
}

The '\0' inside character literals and string literals stands for the character with the code zero. The meaning in C and in Objective C is identical.

To illustrate, you can use \0 in an array initializer to construct an array equivalent to a null-terminated string:

char str1[] = "Hello";
char str2[] = {'H', 'e', 'l', 'l', 'o', '\0'};

In general, you can use \ooo to represent an ASCII character in octal notation, where os stand for up to three octal digits.

Functional requirements are those which are related to the technical functionality of the system.

non-functional requirement is a requirement that specifies criteria that can be used to judge the operation of a system in particular conditions, rather than specific behaviors.

For example if you consider a shopping site, adding items to cart, browsing different items, applying offers and deals and successfully placing orders comes under functional requirements.

Where as performance of the system in peak hours, time taken for the system to retrieve data from DB, security of the user data, ability of the system to handle if large number of users login comes under non functional requirements.

This builds on ntc2 and Chris Johnsen's answer. I am using this whenever I want to create a new session with a custom history-limit. I wanted a way to create sessions with limited scrollback without permanently changing my history-limit for future sessions.

tmux set-option -g history-limit 100 \; new-session -s mysessionname \; set-option -g history-limit 2000

This works whether or not there are existing sessions. After setting history-limit for the new session it resets it back to the default which for me is 2000.

I created an executable bash script that makes this a little more useful. The 1st parameter passed to the script sets the history-limit for the new session and the 2nd parameter sets its session name:

#!/bin/bash
tmux set-option -g history-limit "${1}" \; new-session -s "${2}" \; set-option -g history-limit 2000

I added a modal dialog in jsp and tried to open it with javascript in jsx and hit the same error: "...modal is not a function"

In my case, simply by adding the missing import to the jsx solved the problem.

`import "./../bower/bootstrap/js/modal.js"; // or import ".../bootstrap.min.js"` 

My case, posting alamofire with content-type: "Content-Type":"application/x-www-form-urlencoded", I had to change encoding of alampfire post request

from : JSONENCODING.DEFAULT to: URLEncoding.httpBody

    let body = [
        "UserName": "Minus28",
        "grant_type": "password",
        "Password": "1a29fcd1-2adb-4eaa-9abf-b86607f87085",

A new C++ Excel extension for PHP, though you'll need to build it yourself, and the docs are pretty sparse when it comes to trying to find out what functionality (I can't even find out from the site what formats it supports, or whether it reads or writes or both.... I'm guessing both) it offers is phpexcellib from SIMITGROUP.

All claim to be faster than PHPExcel from codeplex or from github, but (with the exception of COM, PUNO Ilia's wrapper around libXl and spout) they don't offer both reading and writing, or both xls and xlsx; may no longer be supported; and (while I haven't tested Ilia's extension) only COM and PUNO offers the same degree of control over the created workbook.

If you're attaching a database, take a look at the "Databases to attach" grid, and specifically in the Owner column after you've specified your .mdf file. Note the account and give Full Permissions to it for both mdf and ldf files.

I Think this Works:

 testGV.HeaderRow.Cells[0].Text="Date"

Got mine working with

react-native run-ios --device="My’s iPhone"

And notice that your iphone name, the apostrophe s ' might be different. Mine is using this ’

var element = $("#parentDiv .myClassNameOfInterest")

You can use this:

NumberFormat formatter = new DecimalFormat("00");  
String s = formatter.format(1); // ----> 01

In line with the answer given by Denis de Bernardy..

If you want id to be returned afterwards as well and want to insert more things into Table2:

with rows as (
INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id
)
INSERT INTO Table2 (val, val2, val3)
SELECT id, 'val2value', 'val3value'
FROM rows
RETURNING val

Although it's a long time after this question is being asked since I was searching so much for the same problem and couldn't find the extant solutions helpful, I write what fixed my trouble for anyone with the same issue: The point is, Jupyter should be installed in your virtual environment, meaning, after activating the tensorflow environment, run the following in the command prompt (in tensorflow virtual environment):

conda install jupyter
jupyter notebook

and then the jupyter will pop up.

I know this is quite an old post, but I would like to point out the following for people who will read it in the future: As per MS:

Do not use the IISReset.exe tool to restart the IIS services. Instead, use the NET STOP and NET START commands. For example, to stop and start the World Wide Web Publishing Service, run the following commands:

• NET STOP iisadmin /y
• NET START w3svc

There are two benefits to using the NET STOP/NET START commands to restart the IIS Services as opposed to using the IISReset.exe tool. First, it is possible for IIS configuration changes that are in the process of being saved when the IISReset.exe command is run to be lost. Second, using IISReset.exe can make it difficult to identify which dependent service or services failed to stop when this problem occurs. Using the NET STOP commands to stop each individual dependent service will allow you to identify which service fails to stop, so you can then troubleshoot its failure accordingly.

Use a trap!

tempfiles=( )
cleanup() {
  rm -f "${tempfiles[@]}"
}
trap cleanup 0

error() {
  local parent_lineno="$1"
  local message="$2"
  local code="${3:-1}"
  if [[ -n "$message" ]] ; then
    echo "Error on or near line ${parent_lineno}: ${message}; exiting with status ${code}"
  else
    echo "Error on or near line ${parent_lineno}; exiting with status ${code}"
  fi
  exit "${code}"
}
trap 'error ${LINENO}' ERR

...then, whenever you create a temporary file:

temp_foo="$(mktemp -t foobar.XXXXXX)"
tempfiles+=( "$temp_foo" )

and $temp_foo will be deleted on exit, and the current line number will be printed. (set -e will likewise give you exit-on-error behavior, though it comes with serious caveats and weakens code's predictability and portability).

You can either let the trap call error for you (in which case it uses the default exit code of 1 and no message) or call it yourself and provide explicit values; for instance:

error ${LINENO} "the foobar failed" 2

will exit with status 2, and give an explicit message.

A common approach to follow to solve this problem.

1.CHECK your SDK manager by running from your android studio and stand alons sdk folder by executing ./android.sh helps you to find broken packages

2. Try installing System emulator images with google API support than the Intel one. Just like , i solved my problem by running into another system image.

3. Experment on KVM based Virtulaization suggested by Google for Linux

This is my method:

def is_square(n) -> bool:
    return int(n**0.5)**2 == int(n)

Take square root of number. Convert to integer. Take the square. If the numbers are equal, then it is a perfect square otherwise not.

It is incorrect for a large square such as 152415789666209426002111556165263283035677489.

While @ajv-jsy's answer works most of the time, I had the same problem as @MarioVilas. If one of the strings to be compared contains a double quote ("), the variable expansion throws an error.

Example:

@echo off
SetLocal

set Lhs="
set Rhs="

if "%Lhs%" == "%Rhs%" echo Equal

Error:

echo was unexpected at this time.

Solution:

Enable delayed expansion and use ! instead of %.

@echo off
SetLocal EnableDelayedExpansion

set Lhs="
set Rhs="

if !Lhs! == !Rhs! echo Equal

:: Surrounding with double quotes also works but appears (is?) unnecessary.
if "!Lhs!" == "!Rhs!" echo Equal

I have not been able to break it so far using this technique. It works with empty strings and all the symbols I threw at it.

Test:

@echo off
SetLocal EnableDelayedExpansion

:: Test empty string
set Lhs=
set Rhs=
echo Lhs: !Lhs! & echo Rhs: !Rhs!
if !Lhs! == !Rhs! (echo Equal) else (echo Not Equal)
echo.

:: Test symbols
set Lhs= \ / : * ? " ' < > | %% ^^ ` ~ @ # $ [ ] & ( ) + - _ =
set Rhs= \ / : * ? " ' < > | %% ^^ ` ~ @ # $ [ ] & ( ) + - _ =
echo Lhs: !Lhs! & echo Rhs: !Rhs!
if !Lhs! == !Rhs! (echo Equal) else (echo Not Equal)
echo.

From git checkout's usage:

-2, --ours            checkout our version for unmerged files
-3, --theirs          checkout their version for unmerged files
-m, --merge           perform a 3-way merge with the new branch

When resolving merge conflicts, you can do git checkout --theirs some_file, and git checkout --ours some_file to reset the file to the current version and the incoming versions respectively.

If you've done git checkout --ours some_file or git checkout --theirs some_file and would like to reset the file to the 3-way merge version of the file, you can do git checkout --merge some_file.

It looks like SyndFeed is not using generics.

You could either have an unsafe cast and a warning suppression:

@SuppressWarnings("unchecked")
List<SyndEntry> entries = (List<SyndEntry>) sf.getEntries();

or call Collections.checkedList - although you'll still need to suppress the warning:

@SuppressWarnings("unchecked")
List<SyndEntry> entries = Collections.checkedList(sf.getEntries(), SyndEntry.class);

You can combine the two functions; coerce to characters thence to numerics:

> fac <- factor(c("1","2","1","2"))
> as.numeric(as.character(fac))
[1] 1 2 1 2

[xml]$xmlfile = '<xml> <Section name="BackendStatus"> <BEName BE="crust" Status="1" /> <BEName BE="pizza" Status="1" /> <BEName BE="pie" Status="1" /> <BEName BE="bread" Status="1" /> <BEName BE="Kulcha" Status="1" /> <BEName BE="kulfi" Status="1" /> <BEName BE="cheese" Status="1" /> </Section> </xml>'

foreach ($bename in $xmlfile.xml.Section.BEName) {
    if($bename.Status -eq 1){
        #Do something
    }
}

HTML only: use the download attribute:

<a download="logo.gif" href="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7">Download transparent png</a>

Javascript only: you can save any data URI with this code:

function saveAs(uri, filename) {_x000D_
  var link = document.createElement('a');_x000D_
  if (typeof link.download === 'string') {_x000D_
    link.href = uri;_x000D_
    link.download = filename;_x000D_
_x000D_
    //Firefox requires the link to be in the body_x000D_
    document.body.appendChild(link);_x000D_
    _x000D_
    //simulate click_x000D_
    link.click();_x000D_
_x000D_
    //remove the link when done_x000D_
    document.body.removeChild(link);_x000D_
  } else {_x000D_
    window.open(uri);_x000D_
  }_x000D_
}_x000D_
_x000D_
var file = 'data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7'_x000D_
saveAs(file, 'logo.gif');

Chrome, Firefox, and Edge 13+ will use the specified filename.

IE11, Edge 12, and Safari 9 (which don't support the download attribute) will download the file with their default name or they will simply display it in a new tab, if it's of a supported file type: images, videos, audio files, …

A simple and intuitive way would be to use shuf.

Example:

Assume words.txt as:

the
an
linux
ubuntu
life
good
breeze

To shuffle the lines, do:

$ shuf words.txt

which would throws the shuffled lines to standard output; So, you've to pipe it to an output file like:

$ shuf words.txt > shuffled_words.txt

One such shuffle run could yield:

breeze
the
linux
an
ubuntu
good
life

Blob URLs (ref W3C, official name) or Object-URLs (ref. MDN and method name) are used with a Blob or a File object.

src="blob:https://crap.crap" I opened the blob url that was in src of video it gave a error and i can't open but was working with the src tag how it is possible?

Blob URLs can only be generated internally by the browser. URL.createObjectURL() will create a special reference to the Blob or File object which later can be released using URL.revokeObjectURL(). These URLs can only be used locally in the single instance of the browser and in the same session (ie. the life of the page/document).

What is blob url?
Why it is used?

Blob URL/Object URL is a pseudo protocol to allow Blob and File objects to be used as URL source for things like images, download links for binary data and so forth.

For example, you can not hand an Image object raw byte-data as it would not know what to do with it. It requires for example images (which are binary data) to be loaded via URLs. This applies to anything that require an URL as source. Instead of uploading the binary data, then serve it back via an URL it is better to use an extra local step to be able to access the data directly without going via a server.

It is also a better alternative to Data-URI which are strings encoded as Base-64. The problem with Data-URI is that each char takes two bytes in JavaScript. On top of that a 33% is added due to the Base-64 encoding. Blobs are pure binary byte-arrays which does not have any significant overhead as Data-URI does, which makes them faster and smaller to handle.

Can i make my own blob url on a server?

No, Blob URLs/Object URLs can only be made internally in the browser. You can make Blobs and get File object via the File Reader API, although BLOB just means Binary Large OBject and is stored as byte-arrays. A client can request the data to be sent as either ArrayBuffer or as a Blob. The server should send the data as pure binary data. Databases often uses Blob to describe binary objects as well, and in essence we are talking basically about byte-arrays.

if you have then Additional detail

You need to encapsulate the binary data as a BLOB object, then use URL.createObjectURL() to generate a local URL for it:

var blob = new Blob([arrayBufferWithPNG], {type: "image/png"}),
    url = URL.createObjectURL(blob),
    img = new Image();

img.onload = function() {
    URL.revokeObjectURL(this.src);     // clean-up memory
    document.body.appendChild(this);   // add image to DOM
}

img.src = url;                         // can now "stream" the bytes

Note that URL may be prefixed in webkit-browsers, so use:

var url = (URL || webkitURL).createObjectURL(...);

As Geoff says, what Crockford says is good.

The only exception I follow (and have seen widely used) is to use $varname to indicate a jQuery (or whatever library) object. E.g.

var footer = document.getElementById('footer');

var $footer = $('#footer');

The short answer:

Use the click event, which won't fire until after the value has been updated, and fires when you want it to:

<label><input type='checkbox' onclick='handleClick(this);'>Checkbox</label>

function handleClick(cb) {
  display("Clicked, new value = " + cb.checked);
}

Live example | Source

The longer answer:

The change event handler isn't called until the checked state has been updated (live example | source), but because (as Tim Büthe points out in the comments) IE doesn't fire the change event until the checkbox loses focus, you don't get the notification proactively. Worse, with IE if you click a label for the checkbox (rather than the checkbox itself) to update it, you can get the impression that you're getting the old value (try it with IE here by clicking the label: live example | source). This is because if the checkbox has focus, clicking the label takes the focus away from it, firing the change event with the old value, and then the click happens setting the new value and setting focus back on the checkbox. Very confusing.

But you can avoid all of that unpleasantness if you use click instead.

I've used DOM0 handlers (onxyz attributes) because that's what you asked about, but for the record, I would generally recommend hooking up handlers in code (DOM2's addEventListener, or attachEvent in older versions of IE) rather than using onxyz attributes. That lets you attach multiple handlers to the same element and lets you avoid making all of your handlers global functions.

An earlier version of this answer used this code for handleClick:

function handleClick(cb) {
  setTimeout(function() {
    display("Clicked, new value = " + cb.checked);
  }, 0);
}

The goal seemed to be to allow the click to complete before looking at the value. As far as I'm aware, there's no reason to do that, and I have no idea why I did. The value is changed before the click handler is called. In fact, the spec is quite clear about that. The version without setTimeout works perfectly well in every browser I've tried (even IE6). I can only assume I was thinking about some other platform where the change isn't done until after the event. In any case, no reason to do that with HTML checkboxes.

Strings are immutable objects so you can copy them just coping the reference to them, because the object referenced can't change ...

So you can copy as in your first example without any problem :

String s = "hello";
String backup_of_s = s;
s = "bye";

The following approach was inspired by this answer to a related (more general) question.

The approach is to read the MachineGuid value in registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography. This value is generated during OS installation.

There are few ways around the uniqueness of the Hardware-ID per machine using this approach. One method is editing the registry value, but this would cause complications on the user's machine afterwards. Another method is to clone a drive image which would copy the MachineGuid value.

However, no approach is hack-proof and this will certainly be good enough for normal users. On the plus side, this approach is quick performance-wise and simple to implement.

public string GetMachineGuid()
{
   string location = @"SOFTWARE\Microsoft\Cryptography";
   string name = "MachineGuid";

   using (RegistryKey localMachineX64View = 
       RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64))
   {
       using (RegistryKey rk = localMachineX64View.OpenSubKey(location))
       {
           if (rk == null)
               throw new KeyNotFoundException(
                   string.Format("Key Not Found: {0}", location));

           object machineGuid = rk.GetValue(name);
           if (machineGuid == null)
               throw new IndexOutOfRangeException(
                   string.Format("Index Not Found: {0}", name));

           return machineGuid.ToString();
       }
   }
}

Location loc1 = new Location("");
loc1.setLatitude(lat1);
loc1.setLongitude(lon1);

Location loc2 = new Location("");
loc2.setLatitude(lat2);
loc2.setLongitude(lon2);

float distanceInMeters = loc1.distanceTo(loc2);

Reference: http://developer.android.com/reference/android/location/Location.html#distanceTo(android.location.Location)

This worked for me:

[XmlInclude(typeof(BankPayment))]
[Serializable]
public abstract class Payment { }    

[Serializable]
public class BankPayment : Payment {} 

[Serializable]
public class Payments : List<Payment>{}

XmlSerializer serializer = new XmlSerializer(typeof(Payments), new Type[]{typeof(Payment)});

You could compare String representations so:

array1.toString() == array2.toString()
array1.toString() !== array3.toString()

but that would also make

array4 = ['1',2,3,4,5]

equal to array1 if that matters to you

I didn't like any of the implementations (because they use a Regex which is an expensive operation, or a library which is an overkill if you only need one method), so I ended up using the java.net.URI class with some extra checks, and limiting the protocols to: http, https, file, ftp, mailto, news, urn.

And yes, catching exceptions can be an expensive operation, but probably not as bad as Regular Expressions:

final static Set<String> protocols, protocolsWithHost;

static {
  protocolsWithHost = new HashSet<String>( 
      Arrays.asList( new String[]{ "file", "ftp", "http", "https" } ) 
  );
  protocols = new HashSet<String>( 
      Arrays.asList( new String[]{ "mailto", "news", "urn" } ) 
  );
  protocols.addAll(protocolsWithHost);
}

public static boolean isURI(String str) {
  int colon = str.indexOf(':');
  if (colon < 3)                      return false;

  String proto = str.substring(0, colon).toLowerCase();
  if (!protocols.contains(proto))     return false;

  try {
    URI uri = new URI(str);
    if (protocolsWithHost.contains(proto)) {
      if (uri.getHost() == null)      return false;

      String path = uri.getPath();
      if (path != null) {
        for (int i=path.length()-1; i >= 0; i--) {
          if ("?<>:*|\"".indexOf( path.charAt(i) ) > -1)
            return false;
        }
      }
    }

    return true;
  } catch ( Exception ex ) {}

  return false;
}

Yeah this is working, but it returns one row only while there is several rows to retrieve using selected columns only. Like SELECT Title,Date FROM mytable WHERE YEAR(Date)=2017 AND MONTH(Date)=09 returns only one row.

Here is another simple way.

var es, log, logFile;

es = require('event-stream');

log = require('gulp-util').log;

logFile = function(es) {
  return es.map(function(file, cb) {
    log(file.path);
    return cb();
  });
};

gulp.task("do", function() {
 return gulp.src('./examples/*.html')
   .pipe(logFile(es))
   .pipe(gulp.dest('./build'));
});

You can use .filter() method of the Array object:

var filtered = workItems.filter(function(element) {
   // Create an array using `.split()` method
   var cats = element.category.split(' ');

   // Filter the returned array based on specified filters
   // If the length of the returned filtered array is equal to
   // length of the filters array the element should be returned  
   return cats.filter(function(cat) {
       return filtersArray.indexOf(cat) > -1;
   }).length === filtersArray.length;
});

http://jsfiddle.net/6RBnB/

Some old browsers like IE8 doesn't support .filter() method of the Array object, if you are using jQuery you can use .filter() method of jQuery object.

jQuery version:

var filtered = $(workItems).filter(function(i, element) {
   var cats = element.category.split(' ');

    return $(cats).filter(function(_, cat) {
       return $.inArray(cat, filtersArray) > -1;
    }).length === filtersArray.length;
});

I followed everything from here: https://cloud.google.com/compute/docs/instances/connecting-to-instance#generatesshkeypair

But still there was an error and SSH keys in my instance metadata wasn't getting recognized.

Solution: Check if your ssh key has any new-line. When I copied my public key using cat, it added into-lines into the key, thus breaking the key. Had to manually check any line-breaks and correct it.

DANGER - most of these answers will wipe your database and is not recommended for production use.

It's clear there are a lot of "solutions" for this problem, but all these solutions I read through are very destructive solutions and none of them work for a production database. Based on the number of solutions, it also seems that there could be several causes to this error.

My error was being caused by a missing entry in my migrations table. I'm not sure exactly how it happened but by adding it back in I no longer received the error.

renderItem(item)
  {
    const width = '80%';
    var items = [];

    for(let i = 0; i < item.count; i++){

        items.push( <View style={{ padding: 10, borderBottomColor: "#f2f2f2", borderBottomWidth: 10, flexDirection: 'row' }}>
    <View style={{ width }}>
      <Text style={styles.name}>{item.title}</Text>
      <Text style={{ color: '#818181', paddingVertical: 10 }}>{item.taskDataElements[0].description + " "}</Text>
      <Text style={styles.begin}>BEGIN</Text>
    </View>

    <Text style={{ backgroundColor: '#fcefec', padding: 10, color: 'red', height: 40 }}>{this.msToTime(item.minTatTimestamp) <= 0 ? "NOW" : this.msToTime(item.minTatTimestamp) + "hrs"}</Text>
  </View> )
  }

  return items;
}

render() {
return (this.renderItem(this.props.item)) 
}

If you are using beeline to connect to hive, then !dbinfo will give all the underlying database details and in the output getDatabaseProductVersion will have the hive database version.

Sample output: getDatabaseProductVersion 1.2.1000.2.4.3.0-227

To have in Visual Studio Code what you can do in Sublime Text ( CTRL+K CTRL+U and CTRL+K CTRL+L ) you could do this:

• Open "Keyboard Shortcuts" with click on "File -> Preferences -> Keyboard Shortcuts"
• Click on "keybindings.json" link which appears under "Search keybindings" field

• Between the [] brackets add:

  {
      "key": "ctrl+k ctrl+u",
      "command": "editor.action.transformToUppercase",
      "when": "editorTextFocus"
  },
  {
      "key": "ctrl+k ctrl+l",
      "command": "editor.action.transformToLowercase",
      "when": "editorTextFocus"
  }
  

• Save and close "keybindings.json"

To Set JAVA_HOME / PATH for a single user, Login to your account and open .bash_profile file

$ vi ~/.bash_profile

Set JAVA_HOME as follows using syntax export JAVA_HOME=<path-to-java>. If your path is set to /usr/java/jdk1.5.0_07/bin/java, set it as follows:

export JAVA_HOME=/usr/java/jdk1.5.0_07/bin/java

Set PATH as follows:

export PATH=$PATH:/usr/java/jdk1.5.0_07/bin

Feel free to replace /usr/java/jdk1.5.0_07 as per your setup. Save and close the file. Just logout and login back to see new changes. Alternatively, type the following command to activate the new path settings immediately:

$ source ~/.bash_profile

OR

$ . ~/.bash_profile

Verify new settings:

$ echo $JAVA_HOME
$ echo $PATH

Tip: Use the following command to find out exact path to which java executable under UNIX / Linux:

$ which java

Please note that the file ~/.bashrc is similar, with the exception that ~/.bash_profile runs only for Bash login shells and .bashrc runs for every new Bash shell.

To Set JAVA_HOME / PATH for all user, You need to setup global config in /etc/profile OR /etc/bash.bashrc file for all users:

# vi /etc/profile

Next setup PATH / JAVA_PATH variables as follows:

export PATH=$PATH:/usr/java/jdk1.5.0_07/bin
export PATH=$PATH:/usr/java/jdk1.5.0_07/bin

Save and close the file. Once again you need to type the following command to activate the path settings immediately:

# source /etc/profile

OR

# . /etc/profile

Posting Ron E answer for grant privileges on all tables as it might be useful to others.

If you open your resource file and change the access modifier to public or internal it will generate a class from your resource file which allows you to create strongly typed resource references.

Which means you can do something like this instead (using C# 6.0). Then you dont have to remember if firstname was lowercased or camelcased. And you can see if other properties use the same resource value with a find all references.

[Display(Name = nameof(PropertyNames.FirstName), ResourceType = typeof(PropertyNames))]
public string FirstName { get; set; }

A simple solution to this is to edit your /etc/hosts file and establish one alias per project.

127.0.0.1   project1 project2 project3

These domainless names will never have the problem with HSTS unless you send the HSTS response mentioned by @bigjump and with the added benefit of maintaining your login session if you change back and forth between projects.

I think you will have to loop over the "inserted" table, which contains all rows that were updated. You can use a WHERE loop, or a WITH statement if your primary key is a GUID. This is the simpler (for me) to write, so here is my example. We use this approach, so I know for a fact it works fine.

ALTER TRIGGER [dbo].[RA2Newsletter] ON [dbo].[Reiseagent]
    AFTER INSERT
AS
        -- This is your primary key.  I assume INT, but initialize
        -- to minimum value for the type you are using.
        DECLARE @rAgent_ID INT = 0

        -- Looping variable.
        DECLARE @i INT = 0

        -- Count of rows affected for looping over
        DECLARE @count INT

        -- These are your old variables.
        DECLARE @rAgent_Name NVARCHAR(50)
        DECLARE @rAgent_Email NVARCHAR(50)
        DECLARE @rAgent_IP NVARCHAR(50)
        DECLARE @hotelID INT
        DECLARE @retval INT

    BEGIN 
        SET NOCOUNT ON ;

        -- Get count of affected rows
        SELECT  @Count = Count(rAgent_ID)
        FROM    inserted

        -- Loop over rows affected
        WHILE @i < @count
            BEGIN
                -- Get the next rAgent_ID
                SELECT TOP 1
                        @rAgent_ID = rAgent_ID
                FROM    inserted
                WHERE   rAgent_ID > @rAgent_ID
                ORDER BY rAgent_ID ASC

                -- Populate values for the current row
                SELECT  @rAgent_Name = rAgent_Name,
                        @rAgent_Email = rAgent_Email,
                        @rAgent_IP = rAgent_IP,
                        @hotelID = hotelID
                FROM    Inserted
                WHERE   rAgent_ID = @rAgent_ID

                -- Run your stored procedure
                EXEC insert2Newsletter '', '', @rAgent_Name, @rAgent_Email,
                    @rAgent_IP, @hotelID, 'RA', @retval 

                -- Set up next iteration
                SET @i = @i + 1
            END
    END 
GO

I sure hope this helps you out. Cheers!

In addition to using jQuery methods, you can use the native cells collection that the <tr> gives you.

$(t)[0].cells[1].innerHTML

Assuming t is a DOM element, you could bypass the jQuery object creation.

t.cells[1].innerHTML

You have two objects both named bank_holiday -- one a list and one a function. Disambiguate the two.

bank_holiday[month] is raising an error because Python thinks bank_holiday refers to the function (the last object bound to the name bank_holiday), whereas you probably intend it to mean the list.

Here is a quite clean way to end edition with the Return Key or a touch in the background.

In Interface builder, embed your fields in a view of class UIFormView

What does this class :

• Automatically attach itself as fields delegate ( Either awaked from nib, or added manually )
• Keep a reference on the current edited field
• Dismiss the keyboard on return or touch in the background

Here is the code :

Interface

#import <UIKit/UIKit.h>

@interface UIFormView : UIView<UITextFieldDelegate>

-(BOOL)textFieldValueIsValid:(UITextField*)textField;
-(void)endEdit;

@end

Implementation

#import "UIFormView.h"

@implementation UIFormView
{
    UITextField* currentEditingTextField;
}

// Automatically register fields

-(void)addSubview:(UIView *)view
{
    [super addSubview:view];
    if ([view isKindOfClass:[UITextField class]]) {
        if ( ![(UITextField*)view delegate] ) [(UITextField*)view setDelegate:self];
    }
}

// UITextField Protocol

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    currentEditingTextField = textField;
}

-(void)textFieldDidEndEditing:(UITextField *)textField
{
    currentEditingTextField = NULL;
}

-(void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event
{
    [self endEdit];
}

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    if ([self textFieldValueIsValid:textField]) {
        [self endEdit];
        return YES;
    } else {
        return NO;
    }
}

// Own functions

-(void)endEdit
{
    if (currentEditingTextField) {
        [currentEditingTextField endEditing:YES];
        currentEditingTextField = NULL;
    }
}


// Override this in your subclass to handle eventual values that may prevent validation.

-(BOOL)textFieldValueIsValid:(UITextField*)textField
{
    return YES;
}

@end

• By subclassing the form and overriding the textFieldValueIsValid: method, you can avoid end of edition if the value is not correct for the given field.

• If a field has a delegate set in Interface Builder, then the form does not change it. I don't see many reasons to set a different delegate to a particular field, but why not…

There is many ways to improve this form view class - Attach a delegate, do some layout, handle when the keyboards covers a field ( using the currentEditingTextField frame ), automatically start edition for the next field, ...

I personally keep it in my framework, and always subclass it to add features, it is quite often useful "as-is".

I hope it will helps. Cheers all

In your Startup.Auth.cs file add this line:

LoginPath = new PathString("/Account/Login"),

Example:

// Enable the application to use a cookie to store information for the signed in user
// and to use a cookie to temporarily store information about a user logging in with a third party login provider
// Configure the sign in cookie
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
    AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
    LoginPath = new PathString("/Account/Login"),
    Provider = new CookieAuthenticationProvider
    {
        // Enables the application to validate the security stamp when the user logs in.
        // This is a security feature which is used when you change a password or add an external login to your account.  
        OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser>(
        validateInterval: TimeSpan.FromMinutes(30),
        regenerateIdentity: (manager, user) => user.GenerateUserIdentityAsync(manager))
    }
});

Here's a simple script that generally does the trick for me:

SELECT command, percent_complete,total_elapsed_time, estimated_completion_time, start_time
  FROM sys.dm_exec_requests
  WHERE command IN ('RESTORE DATABASE','BACKUP DATABASE') 

Because your function is an instance or non-static function you should create an object first.

Program p=new Program();
p.Add(1,1)

It's worth noting, since it's confusing for people new to XML, that the root (or document node) of an XML document is not the top-level element. It's the parent of the top-level element. This is confusing because it doesn't seem like the top-level element can have a parent. Isn't it the top level?

But look at this, a well-formed XML document:

<?xml-stylesheet href="my_transform.xsl" type="text/xsl"?>
<!-- Comments and processing instructions are XML nodes too, remember. -->
<TopLevelElement/>

The root of this document has three children: a processing instruction, a comment, and an element.

So, for example, if you wanted to write a transform that got rid of that comment, but left in any comments appearing anywhere else in the document, you'd add this to the identity transform:

<xsl:template match="/comment()"/>

Even simpler (and more commonly useful), here's an XPath pattern that matches the document's top-level element irrespective of its name: /*.

You are in wrong directory. cd to your project directory then run composer update.

Bootstrap is Open source HTML Framework. which compatible at almost every Browser. Basically Large Screen Browser width is >992px and extra Large 1200px. so by using Bootstrap defined classes we can adjust screen resolution for displaying contents at every screen from small mobiles to Larger Screen. I tried to explain very short. for Example :

<div class="col-sm-3">....</div>
<div class="col-sm-9">....</div>

<div style="float: left;">Left Div</div>
<div style="float: right;">Right Div</div>

You're swapping endianness between your two methods. You have intToByteArray(int a) assigning the low-order bits into ret[0], but then byteArrayToInt(byte[] b) assigns b[0] to the high-order bits of the result. You need to invert one or the other, like:

public static byte[] intToByteArray(int a)
{
    byte[] ret = new byte[4];
    ret[3] = (byte) (a & 0xFF);   
    ret[2] = (byte) ((a >> 8) & 0xFF);   
    ret[1] = (byte) ((a >> 16) & 0xFF);   
    ret[0] = (byte) ((a >> 24) & 0xFF);
    return ret;
}

You can do this. It looks more wordy than a tuple, but it's a big improvement because you get type checking.

Edit: Replaced snippet with complete working example, following Nick's suggestion. Playground link: http://play.golang.org/p/RNx_otTFpk

package main

import "fmt"

func main() {
    queue := make(chan struct {string; int})
    go sendPair(queue)
    pair := <-queue
    fmt.Println(pair.string, pair.int)
}

func sendPair(queue chan struct {string; int}) {
    queue <- struct {string; int}{"http:...", 3}
}

Anonymous structs and fields are fine for quick and dirty solutions like this. For all but the simplest cases though, you'd do better to define a named struct just like you did.

this code work very well for me: this return the value of selected option. $('#select_id').find('option:selected').val();

I had the same problem and found out that you have to escape spaces in the extra:

adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test\ from\ adb"

So instead of "test from adb" it should be "test\ from\ adb"

If you're using Rails 3+, remove the gem from the Gemfile and run bundle install.

If you're using Rails 2, hopefully you've put the declaration in config/environment.rb. If so, removing it from there and running rake gems:install should do the trick.

You can try this code .

private enum DownloadType {
    AUDIO , VIDEO , AUDIO_AND_VIDEO ;

}

You can use this enumeration as like this : DownloadType.AUDIO.ordinal(). Hope this code snippet will help you .

For Eclipse PDT in Mac OS, once you have deleted the actual workspace directory the option to select and switch to that workspace will still be available unless you delete the entry from Preferences >> General >> Startup and Shutdown >> Workspaces.

As far as I am aware no function exists to return this, you will have to hard set it.

Attempting to cast from values such as 0 to get a minimum date will default to 01-01-1900.

As suggested previously best left set to NULL (and use ISNULL when reading if you need to), or if you are worried about setting it correctly you could even set a trigger on the table to set your modified date on edits.

If you have your heart set on getting the minimum possible date then:

create table atable
(
  atableID int IDENTITY(1, 1) PRIMARY KEY CLUSTERED,
  Modified datetime DEFAULT '1753-01-01'
)

if (c is UserControl) c.Enabled = enable;

T and TRUE are True, F and FALSE are False. T and F can be redefined, however, so you should only rely upon TRUE and FALSE. If you compare 0 to FALSE and 1 to TRUE, you will find that they are equal as well, so you might consider them to be True and False as well.

I would suggest you to use fseek-ftell functions.

FILE *stream = fopen("example.txt", "r");

if(!stream) {
    puts("I/O error.\n");
    return;
}

fseek(stream, 0, SEEK_END);
long size = ftell(stream);
fseek(stream, 0, SEEK_SET);

while(1) {

    if(ftell(stream) == size) {
        break;
    }

    /* INSERT ROUTINE */

}

fclose(stream);

Adding to the other answers, when having a DialogFragment that is full screen calling dismiss() won't pop the DialogFragment from the fragment backstack. A workaround is to call onBackPressed() on the parent activity.

Something like this:

CustomDialogFragment.kt

closeButton.onClick {
    requireActivity().onBackPressed()
}

Whenever I have a class that contains a nested class that is of any significant size/complexity, I mark the class as partial and put the nested class in a separate file. I name the file containing the nested class using the rule: [class name].[nested class name].cs.

The following MSDN blog explains using partial classes with nested classes for maintainability: http://blogs.msdn.com/b/marcelolr/archive/2009/04/13/using-partial-classes-with-nested-classes-for-maintainability.aspx

For example, you have a doc with three fields:

PUT movie/_doc/1
{
  "name":"The Lion King",
  "language":"English",
  "score":"9.3"
}

If you want to return name and score you can use the following command:

GET movie/_doc/1?_source_includes=name,score

If you want to get some fields which match a pattern:

GET movie/_doc/1?_source_includes=*re

Maybe exclude some fields:

GET movie/_doc/1?_source_excludes=score

Just a small adittion to @johnharris85's great answer, when you are running a docker compose file, a "default" network is created so you can just add it to the other compose file as an external network:

# front/docker-compose.yml 
version: '2' 
  services:   
    front_service:
    ...

...

# api/docker-compose.yml
version: '2'
services:
  api_service:
    ...
    networks:
      - front_default
networks:
  front_default:
    external: true

For me this approach was more suited because I did not own the first docker-compose file and wanted to communicate with it.

You may install your coinhsl library in one of your standard libraries directories and run 'ldconfig` before doing your ppyipopt install

The following test works in Chrome 16 (dev branch) on X86 and Chrome 15 on Mac OSX Lion

Connect to the database, then list the tables:

\c liferay
\dt

That's how I do it anyway.

You can combine those two commands onto a single line, if you prefer:

\c liferay \dt

git fetch
git branch --track branch-name origin/branch-name

First command makes sure you have remote branch in local repository. Second command creates local branch which tracks remote branch. It assumes that your remote name is origin and branch name is branch-name.

--track option is enabled by default for remote branches and you can omit it.

Out-of-the-box solution to force JSON.stringify ignore timezones:

• Pure javascript (based on Anatoliy answer):

// Before: JSON.stringify apply timezone offset
const date =  new Date();
let string = JSON.stringify(date);
console.log(string);

// After: JSON.stringify keeps date as-is!
Date.prototype.toJSON = function(){
    const hoursDiff = this.getHours() - this.getTimezoneOffset() / 60;
    this.setHours(hoursDiff);
    return this.toISOString();
};
string = JSON.stringify(date);
console.log(string);

Using moment + moment-timezone libraries:

const date =  new Date();
let string = JSON.stringify(date);
console.log(string);

Date.prototype.toJSON = function(){

You can do objects the JavaScript way... It makes no sense but it works ;)

>>> def FakeObject():
...   def test():
...     print "foo"
...   FakeObject.test = test
...   return FakeObject
>>> x = FakeObject()
>>> x.test()
foo

The equivalent to the accepted answer in jQuery 1.11:

$(window).on("beforeunload", function () {
    return "Please don't leave me!";
});

JSFiddle example

altCognito's answer used the unload event, which happens too late for JavaScript to abort the navigation.

Not quite - since each "left" row in a left-outer-join will match 0-n "right" rows (in the second table), where-as yours matches only 0-1. To do a left outer join, you need SelectMany and DefaultIfEmpty, for example:

var query = from c in db.Customers
            join o in db.Orders
               on c.CustomerID equals o.CustomerID into sr
            from x in sr.DefaultIfEmpty()
            select new {
               CustomerID = c.CustomerID, ContactName = c.ContactName,
               OrderID = x == null ? -1 : x.OrderID };   

(or via the extension methods)

You may face two errors while testing tomcat server startup.

1. Error in the Eclipse inbuilt browser - This page can’t be displayed Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://localhost:8080 again. If this error persists, it is possible that this site uses an unsupported protocol. Please contact the site administrator.
2. 404 error in the normal browsers.

Fixes -

1. For the eclipse browser error, check whether you are using secured URL - https://localhost:8080. This should be http://localhost:8080
2. For the 404 error: Go to Tomcat server in the console. Do a right click, select properties. In the properties window, Click "Switch location" and then click OK. Followed by that, Go to Tomcat server in the console, double click it, Under "server locations" select "Use Tomcat installation" radio button. Save it.

The reason for choosing this option is, When the default option is given as eclipse location, we will see 404 error as it changes Catalina parameters (sometimes). But if we change it to Tomcat location, it works fine.

I see that all answers contain the same: pass by value. However, a recent Brian Goetz update on project Valhalla actually answers it differently:

Indeed, it is a common “gotcha” question about whether Java objects are passed by value or by reference, and the answer is “neither”: object references are passed by value.

You can read more here: State of Valhalla. Section 2: Language Model

Edit: Brian Goetz is Java Language Architect, leading such projects as Project Valhalla and Project Amber.

Edit-2020-12-08: Updated State of Valhalla

You'll need to save as a blob, LONGBLOB datatype in mysql will work.

Ex:

CREATE TABLE 'test'.'pic' (
    'idpic' INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
    'caption' VARCHAR(45) NOT NULL,
    'img' LONGBLOB NOT NULL,
  PRIMARY KEY ('idpic')
)

As others have said, its a bad practice but it can be done. Not sure if this code would scale well, though.

This class-based javascript animation works in AngularJS 1.2 (and 1.4 tested)

Edit: I ended up abandoning this code and went a completely different direction. I like my other answer much better. This answer will give you some problems in certain situations.

myApp.animation('.ng-show-toggle-slidedown', function(){
  return {
    beforeAddClass : function(element, className, done){
        if (className == 'ng-hide'){
            $(element).slideUp({duration: 400}, done);
        } else {done();}
    },
    beforeRemoveClass :  function(element, className, done){
        if (className == 'ng-hide'){
            $(element).css({display:'none'});
            $(element).slideDown({duration: 400}, done);
        } else {done();}
    }
}

});

Simply add the .ng-hide-toggle-slidedown class to the container element, and the jQuery slide down behavior will be implemented based on the ng-hide class.

You must include the $(element).css({display:'none'}) line in the beforeRemoveClass method because jQuery will not execute a slideDown unless the element is in a state of display: none prior to starting the jQuery animation. AngularJS uses the CSS

.ng-hide:not(.ng-hide-animate) {
    display: none !important;
}

to hide the element. jQuery is not aware of this state, and jQuery will need the display:none prior to the first slide down animation.

The AngularJS animation will add the .ng-hide-animate and .ng-animate classes while the animation is occuring.

You actually have one capture group that will match multiple times. Not multiple capture groups.

javascript (js) solution:

let string = "HI,THERE,TOM";
let myRegexp = /([A-Z]+),?/g;       //modify as you like
let match = myRegexp.exec(string);  //js function, output described below
while(match!=null){                 //loops through matches
    console.log(match[1]);          //do whatever you want with each match
    match = myRegexp.exec(bob);     //find next match
}

Output:

HI
THERE
TOM

Syntax:

// matched text: match[0]
// match start: match.index
// capturing group n: match[n]

As you can see, this will work for any number of matches.

In case of complex ProgressBar like this,

use ClipDrawable.

NOTE : I've not used ProgressBar here in this example. I've achieved this using ClipDrawable by clipping image with Animation.

A Drawable that clips another Drawable based on this Drawable's current level value. You can control how much the child Drawable gets clipped in width and height based on the level, as well as a gravity to control where it is placed in its overall container. Most often used to implement things like progress bars, by increasing the drawable's level with setLevel().

NOTE : The drawable is clipped completely and not visible when the level is 0 and fully revealed when the level is 10,000.

I've used this two images to make this CustomProgressBar.

Use win APIs in your main function:

1. RegisterClassEx() note: you have to provide a pointer to a function (usually called WndProc) which handles windows messages such as WM_CREATE, WM_COMMAND etc
2. CreateWindowEx()
3. ShowWindow()
4. UpdateWindow()

Then write another function which handles win's messages (mentioned in #1). When you receive the message WM_CREATE you have to call CreateWindow(). The class is what control is that window, for example "edit" is a text box and "button" is a.. button :). You have to specify an ID for each control (of your choice but unique among all). CreateWindow() returns a handle to that control, which needs to be memorized. When the user clicks on a control you receive the WM_COMMAND message with the ID of that control. Here you can handle that event. You might find useful SetWindowText() and GetWindowText() which allows you to set/get the text of any control.
You will need only the win32 SDK. You can get it here.

sort -u will be slightly faster, because it does not need to pipe the output between two commands

also see my question on the topic: calling uniq and sort in different orders in shell

I tried lots of ways, and found that using datepicker was the best, but the date format causes problems with JavaScript....

$(document).ready(function() {

$( "#startdate,#enddate" ).datepicker({

changeYear: true,
firstDay: 1,
dateFormat: 'dd/mm/yy',
})

$( "#startdate" ).datepicker({ dateFormat: 'dd-mm-yy' });
$( "#enddate" ).datepicker({ dateFormat: 'dd-mm-yy' });

$('#enddate').change(function() {
var start = $('#startdate').datepicker('getDate');
var end   = $('#enddate').datepicker('getDate');

if (start<end) {
var days   = (end - start)/1000/60/60/24;
$('#days').val(days);

Beginners usually try the npm command from random locations. After downloading or creating a project, you have to cd into this project folder. Inside is the file package.json.

cd <path_to_project>
npm install

I use the Min to prevent the negative situations and also handle null strings

// <summary>
    /// Returns a string containing a specified number of characters from the right side of a string.
    /// </summary>
    public static string Right(this string value, int length)
    {
        string result = value;
        if (value != null)
            result = value.Substring(0, Math.Min(value.Length, length));
        return result;
    }

Same problem happened with me . I started eclipse after many days , but it was not starting.just eclipse window flashing , no error nothing. After many trials , i just re-installed my jdk . It worked for me, i think some of my java files were missing or damaged . Try by reinstalling your jdk version it may work as it worked for me.

The insert or replace query would insert a new record if id=1 does not already exist.

The update query would only oudate id=1 if it aready exist, it would not create a new record if it didn't exist.

From your above needs, you will need to use both Python (to export pandas data frame) and VBA (to delete existing worksheet content and copy/paste external data).

With Python: use the to_csv or to_excel methods. I recommend the to_csv method which performs better with larger datasets.

# DF TO EXCEL
from pandas import ExcelWriter

writer = ExcelWriter('PythonExport.xlsx')
yourdf.to_excel(writer,'Sheet5')
writer.save()

# DF TO CSV
yourdf.to_csv('PythonExport.csv', sep=',')

With VBA: copy and paste source to destination ranges.

Fortunately, in VBA you can call Python scripts using Shell (assuming your OS is Windows).

Sub DataFrameImport()
  'RUN PYTHON TO EXPORT DATA FRAME
  Shell "C:\pathTo\python.exe fullpathOfPythonScript.py", vbNormalFocus

  'CLEAR EXISTING CONTENT
  ThisWorkbook.Worksheets(5).Cells.Clear

  'COPY AND PASTE TO WORKBOOK
  Workbooks("PythonExport").Worksheets(1).Cells.Copy
  ThisWorkbook.Worksheets(5).Range("A1").Select
  ThisWorkbook.Worksheets(5).Paste
End Sub

Alternatively, you can do vice versa: run a macro (ClearExistingContent) with Python. Be sure your Excel file is a macro-enabled (.xlsm) one with a saved macro to delete Sheet 5 content only. Note: macros cannot be saved with csv files.

import os
import win32com.client
from pandas import ExcelWriter

if os.path.exists("C:\Full Location\To\excelsheet.xlsm"):
  xlApp=win32com.client.Dispatch("Excel.Application")
  wb = xlApp.Workbooks.Open(Filename="C:\Full Location\To\excelsheet.xlsm")

  # MACRO TO CLEAR SHEET 5 CONTENT
  xlApp.Run("ClearExistingContent")
  wb.Save() 
  xlApp.Quit()
  del xl

  # WRITE IN DATA FRAME TO SHEET 5
  writer = ExcelWriter('C:\Full Location\To\excelsheet.xlsm')
  yourdf.to_excel(writer,'Sheet5')
  writer.save() 

It's ridiculous that java doesn't have this yet. Scala has it

import com.text.Formatter
import com.json.{Formatter => JsonFormatter}

val Formatter textFormatter;
val JsonFormatter jsonFormatter;

%Started Program or Command% | taskkill /F /IM cmd.exe

Example:

notepad.exe | taskkill /F /IM cmd.exe

when u pass any array to some function. u are just passing it's starting address, so for it to work u have to pass it size also for it to work properly. it's the same reason why we pass argc with argv[] in command line arguement.

You can see implementation vc_vector:

struct vc_vector {
  size_t count;
  size_t element_size;
  size_t reserved_size;
  char* data;
  vc_vector_deleter* deleter;
};

...

vc_vector* vc_vector_create_copy(const vc_vector* vector) {
  vc_vector* new_vector = vc_vector_create(vector->reserved_size / vector->count,
                                           vector->element_size,
                                           vector->deleter);
  if (unlikely(!new_vector)) {
    return new_vector;
  }

  if (memcpy(vector->data,
             new_vector->data,
             new_vector->element_size * vector->count) == NULL) {
    vc_vector_release(new_vector);
    new_vector = NULL;
    return new_vector;
  }

  new_vector->count = vector->count;
  return new_vector;
}

To use it:

vc_vector* v1 = vc_vector_create(0, sizeof(int), NULL);
for (int i = 0; i < 10; ++i) {
  vc_vector_push_back(v1, &i);
}

// v1 = 0 1 2 3 4 5 6 7 8 9

vc_vector* v2 = vc_vector_create_copy(v1);

// v2 = 0 1 2 3 4 5 6 7 8 9 (copy of v1)

// to get pointer to int:

const int* v2_data = vc_vector_data(v1);

for me best solotion this is

 Thread.CurrentThread.Abort();

and force close app.

There are actually two ways in which strings can be made in javascript.

1. var str = 'Javascript'; This creates a primitive string value.

2. var obj = new String('Javascript'); This creates a wrapper object of type String.

   typeof str // string
typeof obj // object

So the best way to check for equality is using the === operator because it checks value as well as type of both operands.

If you want to check for equality between two objects then using String.prototype.valueOf is the correct way.

new String('javascript').valueOf() == new String('javascript').valueOf()

Refresh document every 300 seconds using HTML Meta tag add this inside the head tag of the page

I have just started using hooks and I got the above warning when i was calling useEffect inside a function:

Then I have to move the useEffect outside of the function as belows:

 const onChangeRetypePassword = async value => {
  await setRePassword(value);
//previously useEffect was here

  };
//useEffect outside of func 

 useEffect(() => {
  if (password !== rePassword) {
  setPasswdMismatch(true);

     } 
  else{
    setPasswdMismatch(false);
 }
}, [rePassword]);

Hope it will be helpful to someone !

I had the same problem, when I was trying to switch "C:\superfolder"

Error messages:

Directory 'C:\superfolder\subfolder\.svn'
containing
working copy admin area is missing
Please execute the 'Cleanup' command.

After trying to do a "cleanup", I got the following error:

 Cleanup failed to process the following paths:
 C:\superfolder\
'C:\superfolder\subfolder\' is not a working copy directory

Solution:

1. Delete the folder "subfolder"
2. Clean up the folder "superfolder"
3. Try to switch again the folder "superfolder"

this worked for me. Please let me know if it also works for you.

The find function in mongoose is a full query to mongoDB. This means you can use the handy mongoDB $in clause, which works just like the SQL version of the same.

model.find({
    '_id': { $in: [
        mongoose.Types.ObjectId('4ed3ede8844f0f351100000c'),
        mongoose.Types.ObjectId('4ed3f117a844e0471100000d'), 
        mongoose.Types.ObjectId('4ed3f18132f50c491100000e')
    ]}
}, function(err, docs){
     console.log(docs);
});

This method will work well even for arrays containing tens of thousands of ids. (See Efficiently determine the owner of a record)

I would recommend that anybody working with mongoDB read through the Advanced Queries section of the excellent Official mongoDB Docs

Regarding your last question. Most likely you cant solve this inside a single MSI. If you are using registry/system folders or anything related, the MSI itself must be aware of this and you must prepare a 64bit MSI to properly install on 32 bit machine.

There is a possibility that you can make you product installed as a 32 it application and still be able to make it run as 64 bit one, but i think that may be somewhat hard to achieve.

that being said i think you should be able to keep a single code base for everything. In my current work place we have managed to do so. (but it did took some juggling to make everything play together)

Hope this helps. Heres a link to some info related to 32/64 bit issues: http://blog.typemock.com/2008/07/registry-on-windows-64-bit-double-your.html

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

var data =" Retrieves a substring from this instance. The substring starts at a specified character position.";

var result = data.Split(new[] {'.'}, 1)[0];

Output:

Retrieves a substring from this instance. The substring starts at a specified character position.

A cleaner and concise version which I use to upload files on the fly to a given S3 bucket and sub-folder-

import boto3

BUCKET_NAME = 'sample_bucket_name'
PREFIX = 'sub-folder/'

s3 = boto3.resource('s3')

# Creating an empty file called "_DONE" and putting it in the S3 bucket
s3.Object(BUCKET_NAME, PREFIX + '_DONE').put(Body="")

Note: You should ALWAYS put your AWS credentials (aws_access_key_id and aws_secret_access_key) in a separate file, for example- ~/.aws/credentials

map.entrySet().stream()
                .sorted((k1, k2) -> -k1.getValue().compareTo(k2.getValue()))
                .forEach(k -> System.out.println(k.getKey() + ": " + k.getValue()));

Keepin' it simple:

// Find the index of the first element in array
// meeting specified condition.
//
var findIndex = function(arr, cond) {
  var i, x;
  for (i in arr) {
    x = arr[i];
    if (cond(x)) return parseInt(i);
  }
};

var idIsTwo = function(x) { return x.id == 2 }
var tv = [ {id: 1}, {id: 2} ]
var i = findIndex(tv, idIsTwo) // 1

Or, for non-haters, the CoffeeScript variant:

findIndex = (arr, cond) ->
  for i, x of arr
    return parseInt(i) if cond(x)

This question is already answered, but i also got same issue to debug Springboot + gradle + jHipster,

Mostly Spring boot application can debug by right click and debug, but when you use gradle, having some additional environment parameter setup then it is not possible to debug directly.

To resolve this, Eclipse provided one additional features as Remote Java Application

by using this features you can debug your application.

Follow below step:

run your gradle application with ./gradlew bootRun --debug-jvm command

Now go to eclipse --> right click project and Debug configuration --> Remote Java Application.

add you host and port as localhost and port as 5005 (default for gradle debug, you can change it)

Refer for more detail and step.

Date d1 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
            getParameter(date1));
Date d2 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
            getParameter(date2));

long diff = d2.getTime() - d1.getTime();

System.out.println("Difference between  " + d1 + " and "+ d2+" is "
        + (diff / (1000 * 60 * 60 * 24)) + " days.");

CLASSPATH is an environment variable (i.e., global variables of the operating system available to all the processes) needed for the Java compiler and runtime to locate the Java packages used in a Java program. (Why not call PACKAGEPATH?) This is similar to another environment variable PATH, which is used by the CMD shell to find the executable programs.

CLASSPATH can be set in one of the following ways:

CLASSPATH can be set permanently in the environment: In Windows, choose control panel ? System ? Advanced ? Environment Variables ? choose "System Variables" (for all the users) or "User Variables" (only the currently login user) ? choose "Edit" (if CLASSPATH already exists) or "New" ? Enter "CLASSPATH" as the variable name ? Enter the required directories and JAR files (separated by semicolons) as the value (e.g., ".;c:\javaproject\classes;d:\tomcat\lib\servlet-api.jar"). Take note that you need to include the current working directory (denoted by '.') in the CLASSPATH.

To check the current setting of the CLASSPATH, issue the following command:

> SET CLASSPATH

CLASSPATH can be set temporarily for that particular CMD shell session by issuing the following command:

> SET CLASSPATH=.;c:\javaproject\classes;d:\tomcat\lib\servlet-api.jar

Instead of using the CLASSPATH environment variable, you can also use the command-line option -classpath or -cp of the javac and java commands, for example,

> java –classpath c:\javaproject\classes com.abc.project1.subproject2.MyClass3

Q: So my question is this - if throwing from a destructor results in undefined behavior, how do you handle errors that occur during a destructor?

A: There are several options:

1. Let the exceptions flow out of your destructor, regardless of what's going on elsewhere. And in doing so be aware (or even fearful) that std::terminate may follow.

2. Never let exception flow out of your destructor. May be write to a log, some big red bad text if you can.

3. my fave : If std::uncaught_exception returns false, let you exceptions flow out. If it returns true, then fall back to the logging approach.

But is it good to throw in d'tors?

I agree with most of the above that throwing is best avoided in destructor, where it can be. But sometimes you're best off accepting it can happen, and handle it well. I'd choose 3 above.

There are a few odd cases where its actually a great idea to throw from a destructor. Like the "must check" error code. This is a value type which is returned from a function. If the caller reads/checks the contained error code, the returned value destructs silently. But, if the returned error code has not been read by the time the return values goes out of scope, it will throw some exception, from its destructor.

It's not at all related to "tidyr" and "dplyr", but here's another option to consider: merged.stack from my "splitstackshape" package, V1.4.0 and above.

library(splitstackshape)
merged.stack(df, id.vars = c("id", "time"), 
             var.stubs = c("Q3.2.", "Q3.3."),
             sep = "var.stubs")

I can elaborate on the details of DLLs in Windows to help clarify those mysteries to my friends here in *NIX-land...

A DLL is like a Shared Object file. Both are images, ready to load into memory by the program loader of the respective OS. The images are accompanied by various bits of metadata to help linkers and loaders make the necessary associations and use the library of code.

Windows DLLs have an export table. The exports can be by name, or by table position (numeric). The latter method is considered "old school" and is much more fragile -- rebuilding the DLL and changing the position of a function in the table will end in disaster, whereas there is no real issue if linking of entry points is by name. So, forget that as an issue, but just be aware it's there if you work with "dinosaur" code such as 3rd-party vendor libs.

Windows DLLs are built by compiling and linking, just as you would for an EXE (executable application), but the DLL is meant to not stand alone, just like an SO is meant to be used by an application, either via dynamic loading, or by link-time binding (the reference to the SO is embedded in the application binary's metadata, and the OS program loader will auto-load the referenced SO's). DLLs can reference other DLLs, just as SOs can reference other SOs.

In Windows, DLLs will make available only specific entry points. These are called "exports". The developer can either use a special compiler keyword to make a symbol an externally-visible (to other linkers and the dynamic loader), or the exports can be listed in a module-definition file which is used at link time when the DLL itself is being created. The modern practice is to decorate the function definition with the keyword to export the symbol name. It is also possible to create header files with keywords which will declare that symbol as one to be imported from a DLL outside the current compilation unit. Look up the keywords __declspec(dllexport) and __declspec(dllimport) for more information.

One of the interesting features of DLLs is that they can declare a standard "upon load/unload" handler function. Whenever the DLL is loaded or unloaded, the DLL can perform some initialization or cleanup, as the case may be. This maps nicely into having a DLL as an object-oriented resource manager, such as a device driver or shared object interface.

When a developer wants to use an already-built DLL, she must either reference an "export library" (*.LIB) created by the DLL developer when she created the DLL, or she must explicitly load the DLL at run time and request the entry point address by name via the LoadLibrary() and GetProcAddress() mechanisms. Most of the time, linking against a LIB file (which simply contains the linker metadata for the DLL's exported entry points) is the way DLLs get used. Dynamic loading is reserved typically for implementing "polymorphism" or "runtime configurability" in program behaviors (accessing add-ons or later-defined functionality, aka "plugins").

The Windows way of doing things can cause some confusion at times; the system uses the .LIB extension to refer to both normal static libraries (archives, like POSIX *.a files) and to the "export stub" libraries needed to bind an application to a DLL at link time. So, one should always look to see if a *.LIB file has a same-named *.DLL file; if not, chances are good that *.LIB file is a static library archive, and not export binding metadata for a DLL.

I think this is important to consider for cross-platform execution, i.e. as a CYA. :)

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.

This is directly quoted from Python Software Foundation 2.7.x.

If you can't go over your time limit (it's a hard limit) then a thread is your best bet. You can use a loop to terminate the thread once you get to the time threshold. Whatever is going on in that thread at the time can be interrupted, allowing calculations to stop almost instantly. Here is an example:

Thread t = new Thread(myRunnable); // myRunnable does your calculations

long startTime = System.currentTimeMillis();
long endTime = startTime + 60000L;

t.start(); // Kick off calculations

while (System.currentTimeMillis() < endTime) {
    // Still within time theshold, wait a little longer
    try {
         Thread.sleep(500L);  // Sleep 1/2 second
    } catch (InterruptedException e) {
         // Someone woke us up during sleep, that's OK
    }
}

t.interrupt();  // Tell the thread to stop
t.join();       // Wait for the thread to cleanup and finish

That will give you resolution to about 1/2 second. By polling more often in the while loop, you can get that down.

Your runnable's run would look something like this:

public void run() {
    while (true) {
        try {
            // Long running work
            calculateMassOfUniverse();
        } catch (InterruptedException e) {
            // We were signaled, clean things up
            cleanupStuff();
            break;           // Leave the loop, thread will exit
    }
}

Update based on Dmitri's answer

Dmitri pointed out TimerTask, which would let you avoid the loop. You could just do the join call and the TimerTask you setup would take care of interrupting the thread. This would let you get more exact resolution without having to poll in a loop.

I hit the same problem on my laptop(win 10) with Wireshark(version 3.2.0), and I tried all the above solutions but unfortunately don't help.

So,

I uninstall the Wireshark bluntly and reinstall it.

After that, this problem solved.

Putting the solution here, and wish it may help someone......

The Simple 1:1 Scenario

For situations where the canvas element is 1:1 compared to the bitmap size, you can get the mouse positions by using this snippet:

function getMousePos(canvas, evt) {
    var rect = canvas.getBoundingClientRect();
    return {
      x: evt.clientX - rect.left,
      y: evt.clientY - rect.top
    };
}

Just call it from your event with the event and canvas as arguments. It returns an object with x and y for the mouse positions.

As the mouse position you are getting is relative to the client window you'll have to subtract the position of the canvas element to convert it relative to the element itself.

Example of integration in your code:

//put this outside the event loop..
var canvas = document.getElementById("imgCanvas");
var context = canvas.getContext("2d");

function draw(evt) {
    var pos = getMousePos(canvas, evt);

    context.fillStyle = "#000000";
    context.fillRect (pos.x, pos.y, 4, 4);
}

Note: borders and padding will affect position if applied directly to the canvas element so these needs to be considered via getComputedStyle() - or apply those styles to a parent div instead.

When Element and Bitmap are of different sizes

When there is the situation of having the element at a different size than the bitmap itself, for example, the element is scaled using CSS or there is pixel-aspect ratio etc. you will have to address this.

Example:

function  getMousePos(canvas, evt) {
  var rect = canvas.getBoundingClientRect(), // abs. size of element
      scaleX = canvas.width / rect.width,    // relationship bitmap vs. element for X
      scaleY = canvas.height / rect.height;  // relationship bitmap vs. element for Y

  return {
    x: (evt.clientX - rect.left) * scaleX,   // scale mouse coordinates after they have
    y: (evt.clientY - rect.top) * scaleY     // been adjusted to be relative to element
  }
}

With transformations applied to context (scale, rotation etc.)

Then there is the more complicated case where you have applied transformation to the context such as rotation, skew/shear, scale, translate etc. To deal with this you can calculate the inverse matrix of the current matrix.

Newer browsers let you read the current matrix via the currentTransform property and Firefox (current alpha) even provide a inverted matrix through the mozCurrentTransformInverted. Firefox however, via mozCurrentTransform, will return an Array and not DOMMatrix as it should. Neither Chrome, when enabled via experimental flags, will return a DOMMatrix but a SVGMatrix.

In most cases however you will have to implement a custom matrix solution of your own (such as my own solution here - free/MIT project) until this get full support.

When you eventually have obtained the matrix regardless of path you take to obtain one, you'll need to invert it and apply it to your mouse coordinates. The coordinates are then passed to the canvas which will use its matrix to convert it to back wherever it is at the moment.

This way the point will be in the correct position relative to the mouse. Also here you need to adjust the coordinates (before applying the inverse matrix to them) to be relative to the element.

An example just showing the matrix steps

function draw(evt) {
    var pos = getMousePos(canvas, evt);        // get adjusted coordinates as above
    var imatrix = matrix.inverse();            // get inverted matrix somehow
    pos = imatrix.applyToPoint(pos.x, pos.y);  // apply to adjusted coordinate

    context.fillStyle = "#000000";
    context.fillRect(pos.x-1, pos.y-1, 2, 2);
}

An example of using currentTransform when implemented would be:

    var pos = getMousePos(canvas, e);          // get adjusted coordinates as above
    var matrix = ctx.currentTransform;         // W3C (future)
    var imatrix = matrix.invertSelf();         // invert

    // apply to point:
    var x = pos.x * imatrix.a + pos.y * imatrix.c + imatrix.e;
    var y = pos.x * imatrix.b + pos.y * imatrix.d + imatrix.f;

Update I made a free solution (MIT) to embed all these steps into a single easy-to-use object that can be found here and also takes care of a few other nitty-gritty things most ignore.

This is how I did it using promises in node. Pollings stop after making the first request.

 var axios = require('axios');
    var CancelToken = axios.CancelToken;
    var cancel;
    axios.get('www.url.com',
                      {
                        cancelToken: new CancelToken(
                            function executor(c) {
                                cancel = c;
                             })
                      }
            ).then((response) =>{            
                cancel();               
              })

If you need to use " and " instead of ", " between the last two items you can do this:

function arrayToList(array){
  return array
    .join(", ")
    .replace(/, ((?:.(?!, ))+)$/, ' and $1');
}

Using can also use Java 8 stream API and do the same thing in one line.

If you want to print any specific property then use this syntax:

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(room -> System.out.println(room.getName()));

OR

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(room -> {
    // here room is available
});

if you want to print all the properties of Java object then use this:

ArrayList<Room> rooms = new ArrayList<>();
rooms.forEach(System.out::println);

in support libraries you always need to add three numbers as version number

Suppose for 22 -> you need to write it as 22.0.0, not just 22

for 22.1 -> 22.1.0

So your dependencies should look like this

compile 'com.android.support:appcompat-v7:22.0.0'
compile 'com.android.support:support-v4:22.0.0'
compile 'com.android.support:cardview-v7:22.0.0'
compile 'com.android.support:recyclerview-v7:22.0.0'

I Programmers language you need to pad extra zeros.

Hope this solves your problem

You can listen resize event and fire where some dimension change

directive

(function() {
'use strict';

    angular
    .module('myApp.directives')
    .directive('resize', ['$window', function ($window) {
        return {
            link: link,
            restrict: 'A'
        };

        function link(scope, element, attrs){
            scope.width = $window.innerWidth;
            function onResize(){
                // uncomment for only fire when $window.innerWidth change   
                // if (scope.width !== $window.innerWidth)
                {
                    scope.width = $window.innerWidth;
                    scope.$digest();
                }
            };

            function cleanUp() {
                angular.element($window).off('resize', onResize);
            }

            angular.element($window).on('resize', onResize);
            scope.$on('$destroy', cleanUp);
        }
    }]);
})();

In html

<div class="row" resize> ,
    <div class="col-sm-2 col-xs-6" ng-repeat="v in tag.vod"> 
        <h4 ng-bind="::v.known_as"></h4>
    </div> 
</div> 

Controller :

$scope.$watch('width', function(old, newv){
     console.log(old, newv);
 })

You can use calc() in combination with var() to sort of mimic conditionals:

:root {
--var-eq-two: 0;
}

.var-eq-two {
    --var-eq-two: 1;
}

.block {
    background-position: calc(
        150px * var(--var-eq-two) +
        4px * (1 - var(--var-eq-two))
    ) 8px;
}

concept

It's part of the ES6 module system, described here. There is a helpful example in that documentation, also:

If a module defines a default export:

export default function() { console.log("hello!") }

then you can import that default export by omitting the curly braces:

import foo from "foo";
foo(); // hello!

Update: As of June 2015, the module system is defined in §15.2 and the export syntax in particular is defined in §15.2.3 of the ECMAScript 2015 specification.

You should try something running Mono (its compatible with .NET).

For game development, I recommend unity: http://unity3d.com/

for general aplications: http://xamarin.com/monoforandroid

I think you cannot speak of a "conversion" here. That will be a whole project. To "convert" it i think you have to write it again for the iphone.

Have a look at this question:

Is there a multiplatform framework for developing iPhone / Android applications?

As you can see from the answers there, there is no good way of developing applications for both platforms at the same time (except if you're developing games where flash makes it easy to be portable).

var myText = 'GOOGLE';

$('#HowYouKnow option').map(function() {
    if ($(this).text() == myText) return this;
}).attr('selected', 'selected');

If you read the bootstrap 4 documentation, Color schemes, it will answer your questions.

If getting this error trying to build .Net Core 2.0 app on VSTS then ensure your build definition is using the Hosted VS2017 Agent queue.

I solved the problem by removing ~/Library/Caches/com.apple.amp.itmstransporter. For safety, renaming will be better,

cd ~/Library/Caches
mv com.apple.amp.itmstransporter com.apple.amp.itmstransporter.old

Then, xcrun altool uploaded my ipa successfully.
By the way, I'm using Xcode 11.x & 12.2, macOS Catalina.

If you don't need a separated class, i mean just a simple adapter mapped on your object. Here is my code based on ArrayAdapter functions provided.

And because you might need to add item after adapter creation (eg database item asynchronous loading).

Simple but efficient.

editCategorySpinner = view.findViewById(R.id.discovery_edit_category_spinner);

// Drop down layout style - list view with radio button         
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

// attaching data adapter to spinner, as you can see i have no data at this moment
editCategorySpinner.setAdapter(dataAdapter);
final ArrayAdapter<Category> dataAdapter = new ArrayAdapter<Category>

(getActivity(), android.R.layout.simple_spinner_item, new ArrayList<Category>(0)) {


        // And the "magic" goes here
        // This is for the "passive" state of the spinner
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // I created a dynamic TextView here, but you can reference your own  custom layout for each spinner item
            TextView label = (TextView) super.getView(position, convertView, parent);
            label.setTextColor(Color.BLACK);
            // Then you can get the current item using the values array (Users array) and the current position
            // You can NOW reference each method you has created in your bean object (User class)
            Category item = getItem(position);
            label.setText(item.getName());

            // And finally return your dynamic (or custom) view for each spinner item
            return label;
        }

        // And here is when the "chooser" is popped up
        // Normally is the same view, but you can customize it if you want
        @Override
        public View getDropDownView(int position, View convertView,
                                    ViewGroup parent) {
            TextView label = (TextView) super.getDropDownView(position, convertView, parent);
            label.setTextColor(Color.BLACK);
            Category item = getItem(position);
            label.setText(item.getName());

            return label;
        }
    };

And then you can use this code (i couldn't put Category[] in adapter constructor because data are loaded separatly).

Note that adapter.addAll(items) refresh spinner by calling notifyDataSetChanged() in internal.

categoryRepository.getAll().observe(this, new Observer<List<Category>>() {

            @Override
            public void onChanged(@Nullable final List<Category> items) {
                dataAdapter.addAll(items);
            }
});

add

z-index:1151;

to the style sheet in

.datepicker

fun rotateArrow(view: View): Boolean {
    return if (view.rotation == 0F) {
        view.animate().setDuration(200).rotation(180F)
        true
    } else {
         view.animate().setDuration(200).rotation(0F)
         false
    }
}

I was facing the same problem and found a solution to get the code to work.

The code given in the android-Sdk/samples/android-?/ApiDemos works fine. Copy paste each folder in the android project and then in the MediaPlayerDemo_Video.java put the path of the video you want to stream in the path variable. It is left blank in the code.

The following video stream worked for me: http://www.pocketjourney.com/downloads/pj/video/famous.3gp

I know that RTSP protocol is to be used for streaming, but mediaplayer class supports http for streaming as mentioned in the code.

I googled for the format of the video and found that the video if converted to mp4 or 3gp using Quicktime Pro works fine for streaming.

I tested the final apk on android 2.1. The application dosent work on emulators well. Try it on devices.

I hope this helps..

SELECT CUSTOMER, COUNT(*) as PETS 
FROM table_name 
GROUP BY CUSTOMER;

drupal_get_destination() has some internal code that points at the correct place to getthe current internal path. To translate that path into an absolute URL, the url() function should do the trick. If the 'absolute' option is passed in it will generate the full URL, not just the internal path. It will also swap in any path aliases for the current path as well.

$path = isset($_GET['q']) ? $_GET['q'] : '<front>';
$link = url($path, array('absolute' => TRUE));

Another way to get a subset of columns from your DataFrame, assuming you want all the rows, would be to do:
data[['a','b']] and data[['c','d','e']]
If you want to use numerical column indexes you can do:
data[data.columns[:2]] and data[data.columns[2:]]

Frankly the errors are really hard to see, especially if only one character is "underwaved" in a sea of Java code. I used the instructions above to make the background an orangey-red color and things are much more obvious.

If you don't know which extension you have, then you can try this:

$ext = strtolower(substr('yourFileName.ext', strrpos('yourFileName.ext', '.') + 1));
echo basename('yourFileName.ext','.'.$ext); // output: "youFileName" only

Working with all possibilities:

image.jpg // output: "image"
filename.image.png // output: "filename.image"
index.php // output: "index"

some_list[-1] is the shortest and most Pythonic.

In fact, you can do much more with this syntax. The some_list[-n] syntax gets the nth-to-last element. So some_list[-1] gets the last element, some_list[-2] gets the second to last, etc, all the way down to some_list[-len(some_list)], which gives you the first element.

You can also set list elements in this way. For instance:

>>> some_list = [1, 2, 3]
>>> some_list[-1] = 5 # Set the last element
>>> some_list[-2] = 3 # Set the second to last element
>>> some_list
[1, 3, 5]

Note that getting a list item by index will raise an IndexError if the expected item doesn't exist. This means that some_list[-1] will raise an exception if some_list is empty, because an empty list can't have a last element.

When in doubt, write a unit test:

@Test
public void trimRemoveAllBlanks(){
    assertThat("    content   ".trim(), is("content"));
}

NB: of course the test (for JUnit + Hamcrest) doesn't fail

The following does not return a response:

You must return anything like return afunction() or return 'a string'.

This can solve the issue

Well, there's always the brute force method:

<li><pre>    The lazy dog.</pre></li>
<li><pre>AND The lazy cat.</pre></li>
<li><pre>OR  The active goldfish.</pre></li>

Or is that what you meant by "padding" the text? That's an ambiguous work in this context.

This sounds kind of like a homework question. I hope you're not trying to get us to do your homework for you?

This works very well.

ArrayList<String[]> a = new ArrayList<String[]>();
    a.add(new String[3]);
    a.get(0)[0] = "Zubair";
    a.get(0)[1] = "Borkala";
    a.get(0)[2] = "Kerala";
System.out.println(a.get(0)[1]);

Result will be

Borkala

One more way of running an R script from the command line would be:

R < scriptName.R --no-save  

or with --save.

See also What's the best way to use R scripts on the command line (terminal)?.

1. Open config/database.php
2. Find strict key inside mysql connection settings
3. Set the value to false

If you want the latest file in the directory and you are using only the LastWriteTime to determine the latest file, you can do something like below:

gci path | sort LastWriteTime | select -last 1

On the other hand, if you want to only rely on the names that have the dates in them, you should be able to something similar

gci path | select -last 1

Also, if there are directories in the directory, you might want to add a ?{-not $_.PsIsContainer}

What about

str1.localeCompare(str2)

var host = location.protocol + '//' + location.host + '/';

"it only prints a word lets say only 'Archbishop' from 'Archbishop Street"

It is only printing the word because Scanner functions such as next(), nextInt(), etc. read only a token at time. Thus this function reads and returns the next token.

For example if you have: x y z
 s.next() will return x
 s.nextLine() y z

Going back to your code if you want to read the whole line "Archbishop Street"

String address = s.next(); // s = "Archbishop"
Then address += s.nextLine(); // s = s + " Street"

math.log is the natural logarithm:

From the documentation:

math.log(x[, base]) With one argument, return the natural logarithm of x (to base e).

Your equation is therefore:

n = math.log((1 + (FV * r) / p) / math.log(1 + r)))

Note that in your code you convert n to a str twice which is unnecessary

'Windows error 2' has dozens of meanings (52 that I could find).

The most common one is ERROR_FILE_NOT_FOUND, which can be found in winerror.h. Without more context, that's the best I can guess. Did you check the event logs to see if there's more information there?

It's actually much easier with jQuery's promise API:

$.ajax(
            type: "GET",
            url: requestURL,
        ).then((success) =>
            console.dir(success)
        ).failure((failureResponse) =>
            console.dir(failureResponse)
        )

Alternatively, you can pass in of bind functions to each result callback; the order of parameters is: (success, failure). So long as you specify a function with at least 1 parameter, you get access to the response. So, for example, if you wanted to check the response text, you could simply do:

$.ajax(
            type: "GET",
            url: @get("url") + "logout",
            beforeSend: (xhr) -> xhr.setRequestHeader("token", currentToken)
        ).failure((response) -> console.log "Request was unauthorized" if response.status is 401

That error means that the compiler is not able to find the definition of the type of your struct before the declaration of the array of structs, since you're saying you have the definition of the struct in a header file and the error is in nbody.c then you should check if you're including correctly the header file. Check your #include's and make sure the definition of the struct is done before declaring any variable of that type.

you need to use display = none

value hidden is connected with attributet called visibility

so your code should look like this

<script type="text/javascript">
function hide(){
document.getElementById("test").style.display="none";
}
</script>

if you set style="height:100px;" on a td if the td has content that grows the cell more than that, it will do so no need for min height on a td.

Assuming your Generic List is of type String:

TextWriter tw = new StreamWriter("SavedList.txt");

foreach (String s in Lists.verbList)
   tw.WriteLine(s);

tw.Close();

Alternatively, with the using keyword:

using(TextWriter tw = new StreamWriter("SavedList.txt"))
{
   foreach (String s in Lists.verbList)
      tw.WriteLine(s);
}

Yes, you can find the best number of clusters using Elbow method, but I found it troublesome to find the value of clusters from elbow graph using script. You can observe the elbow graph and find the elbow point yourself, but it was lot of work finding it from script.

So another option is to use Silhouette Method to find it. The result from Silhouette completely comply with result from Elbow method in R.

Here`s what I did.

#Dataset for Clustering
n = 150
g = 6 
set.seed(g)
d <- data.frame(x = unlist(lapply(1:g, function(i) rnorm(n/g, runif(1)*i^2))), 
                y = unlist(lapply(1:g, function(i) rnorm(n/g, runif(1)*i^2))))
mydata<-d
#Plot 3X2 plots
attach(mtcars)
par(mfrow=c(3,2))

#Plot the original dataset
plot(mydata$x,mydata$y,main="Original Dataset")

#Scree plot to deterine the number of clusters
wss <- (nrow(mydata)-1)*sum(apply(mydata,2,var))
  for (i in 2:15) {
    wss[i] <- sum(kmeans(mydata,centers=i)$withinss)
}   
plot(1:15, wss, type="b", xlab="Number of Clusters",ylab="Within groups sum of squares")

# Ward Hierarchical Clustering
d <- dist(mydata, method = "euclidean") # distance matrix
fit <- hclust(d, method="ward") 
plot(fit) # display dendogram
groups <- cutree(fit, k=5) # cut tree into 5 clusters
# draw dendogram with red borders around the 5 clusters 
rect.hclust(fit, k=5, border="red")

#Silhouette analysis for determining the number of clusters
library(fpc)
asw <- numeric(20)
for (k in 2:20)
  asw[[k]] <- pam(mydata, k) $ silinfo $ avg.width
k.best <- which.max(asw)

cat("silhouette-optimal number of clusters:", k.best, "\n")
plot(pam(d, k.best))

# K-Means Cluster Analysis
fit <- kmeans(mydata,k.best)
mydata 
# get cluster means 
aggregate(mydata,by=list(fit$cluster),FUN=mean)
# append cluster assignment
mydata <- data.frame(mydata, clusterid=fit$cluster)
plot(mydata$x,mydata$y, col = fit$cluster, main="K-means Clustering results")

Hope it helps!!

You can't extend TextView to create a widget or use one in a widgets layout: http://developer.android.com/guide/topics/appwidgets/index.html

$.ajax({
        url: 'mail3.php',
        type: 'POST',
        data: 'contactName=' + name + '&contactEmail=' + email + '&spam=' + spam,

        success: function(result) {

            //console.log(result);
            $('#results,#errors').remove();
            $('#contactWrapper').append('<p id="results">' + result + '</p>');
            $('#loading').fadeOut(500, function() {
                $(this).remove();

            });

            if(result === "no_errors") location.href = "http://www.example.com/ThankYou.html"

        }
    });

After the GitHub update 01.10.20 you should use main instead of master.

Do it like these way...

1. Create a repository on GitHub
2. Delete existing .git file on your local directory
3. Go to local project directory and type git init
4. git add .
5. git commit -m"My First Commmit"
6. Now check your branch name it will be master in your local project
7. git remote add origin <remote repository URL past here from the github repository> then type git remote -v
8. git push -f origin master
9. Now check the github repository you will see two branch 1. main 2. master
10. In your local repository create new branch and the branch name will be main
11. git checkout main
12. git merge master
13. git pull origin main
14. git push -f origin main

Note: from 01.10.20 github decided use main instead of master branch use default branch name

I have gone around and found this free plugin https://wordpress.org/plugins/filebird/ after very tired with a lots of files in my WordPress default media management. After I installed the plugin, I am able to organize all images and other files into folders/ categories, just drag and drop to upload/move files into folders and drag and drop to rearrange folders.

Not 96x96, use 64x64 instead. I usually use:

• 16 - status/titlebar button
• 32 - desktop icon
• 48 - folder view
• 64/128 - Additional sizes

256 works as well on XP, however, old resource compilers sometimes complained about "out of memory" errors.

You have specified the ajax call response dataType as:

'json'

where as the actual ajax response is not a valid JSON and as a result the JSON parser is throwing an error.

The best approach that I would recommend is to change the dataType to:

'text'

and within the success callback validate whether a valid JSON is being returned or not, and if JSON validation fails, alert it on the screen so that its obvious for what purpose the ajax call is actually failing. Have a look at this:

$.ajax({
    url: '/Admin/Ajax/GetViewContentNames',
    type: 'POST',
    dataType: 'text',
    data: {viewID: $("#view").val()},
    success: function (data) {
        try {
            var output = JSON.parse(data);
            alert(output);
        } catch (e) {
            alert("Output is not valid JSON: " + data);
        }
    }, error: function (request, error) {
        alert("AJAX Call Error: " + error);
    }
});

You can try this, see if it works for you.

Rather than choosing date from date picker, you can enable the date box using javascript & enter the required date, this would avoid excessive time required to traverse through all date elements till you reach one you require to select.

Code for from date

((JavascriptExecutor)driver).executeScript ("document.getElementById('fromDate').removeAttribute('readonly',0);"); // Enables the from date box

WebElement fromDateBox= driver.findElement(By.id("fromDate"));
fromDateBox.clear();
fromDateBox.sendKeys("8-Dec-2014"); //Enter date in required format

Code for to date

((JavascriptExecutor)driver).executeScript ("document.getElementById('toDate').removeAttribute('readonly',0);"); // Enables the from date box

WebElement toDateBox= driver.findElement(By.id("toDate"));
toDateBox.clear();
toDateBox.sendKeys("15-Dec-2014"); //Enter date in required format

The SQL Query select * from openjson ... works only with SQL version 2016 and higher. Need the SQL compatibility mode 130.

When using guava (See doc) there is Iterators.forEnumeration. Given an Enumeration x you can do the following:

to get a immutable Set:

ImmutableSet.copyOf(Iterators.forEnumeration(x));

to get a immutable List:

ImmutableList.copyOf(Iterators.forEnumeration(x));

to get a hashSet:

Sets.newHashSet(Iterators.forEnumeration(x));

It's in the @@SERVERNAME variable;

SELECT @@SERVERNAME;

public class Program
{
    public static void Main(string[] args)
    {
        int[] arr = new int[]{10, 5, 10, 2, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11, 12, 12};

        int numberOfDuplicate = 0;
        int arrayLength = arr.Length;

        for(int i=0; i < arrayLength; i++)  
        {  
           for(int j = 1; j < arrayLength; j++)  
           {
               if(j < i && arr[j]==arr[i])
               {
                  break; 
               }
               else if(i != j && arr[i]==arr[j])
               {
                  Console.Write("duplicate : arr[{0}]={1}--arr[{2}]={3}\n",i,arr[i],j,arr[j]);
                  numberOfDuplicate++;
                  break;
               }
           }
        }

        Console.Write("Total duplicate element in an array 'arr' is {0}\n ",numberOfDuplicate);
    }
}

I ran into problems with & and |, which exit statuses and error throwing, respectively.

Other solutions want to run any task with a given name, like npm-run-all, which wasn't my use case.

So I created npm-run-parallel that runs npm scripts asynchronously and reports back when they're done.

So, for your scripts, it'd be:

npm-run-parallel wp-server start-watch

Use name() when you want to make a comparison or use the hardcoded value for some internal use in your code.

Use toString() when you want to present information to a user (including a developper looking at a log). Never rely in your code on toString() giving a specific value. Never test it against a specific string. If your code breaks when someone correctly changes the toString() return, then it was already broken.

From the javadoc (emphasis mine) :

Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

In IE9, it is possible with purely a hack as advised by @Spudley. Since you've customized height and width of the div and select, you need to change div:before css to match yours.

In case if it is IE10 then using below css3 it is possible

select::-ms-expand {
    display: none;
}

However if you're interested in jQuery plugin, try Chosen.js or you can create your own in js.

Shift + Alt + r (Right click file -> Refactor -> Rename) when cursor is on class name. The file and constructors will be also changed.

Binder uses "Observer Pattern" for Death Recipient notifications.

How about alert(JSON.stringify(object)) with a modern browser?

In case of TypeError: Converting circular structure to JSON, here are more options: How to serialize DOM node to JSON even if there are circular references?

The documentation: JSON.stringify() provides info on formatting or prettifying the output.

Use:

if (condition) {
    i = j = 1000;
    break;
}

I depends heavily on which number formats you aim to support, and how strict you want to enforce number grouping, use of whitespace and other separators etc....

Take a look at this similar question to get some ideas.

Then there is E.164 which is a numbering standard recommendation from ITU-T

Your mock is raising the exception just fine, but the error.resp.status value is missing. Rather than use return_value, just tell Mock that status is an attribute:

barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')

Additional keyword arguments to Mock() are set as attributes on the resulting object.

I put your foo and bar definitions in a my_tests module, added in the HttpError class so I could use it too, and your test then can be ran to success:

>>> from my_tests import foo, HttpError
>>> import mock
>>> with mock.patch('my_tests.bar') as barMock:
...     barMock.side_effect = HttpError(mock.Mock(status=404), 'not found')
...     result = my_test.foo()
... 
404 - 
>>> result is None
True

You can even see the print '404 - %s' % error.message line run, but I think you wanted to use error.content there instead; that's the attribute HttpError() sets from the second argument, at any rate.

AsyncTask is very helpful!
