Please take following steps:

1. As other friends mentioned, you should make a directory first for your database data to be stored. This folder could be something like:

   C:\mongo-data

2. From command line navigate to where you have installed mongodb and where mongod.exe resides. In my case the full path is:

   C:\Program Files\MongoDB\Server\3.4\bin

3. From here run mongod.exe and pass it the path to the folder you created in step one using the flag --dbpath as follows:

   mongod.exe --dbpath "C:\mongo-data"

Please Note: If you are on windows it is necessary to use double-quotes ("") in the above to run properly.

In this way you will get something like the following:

2017-06-14T12:45:59.892+0430 I NETWORK  [thread1] waiting for connections on port 27017

If you use single quotes (' ') on windows, you will get:

2017-06-14T01:13:45.965-0700 I CONTROL  [initandlisten] shutting down with code:100

Hope it helps to resolve the issue.

This worked for me in Bitbucket Cloud.

Entering this:

* item a
* item b
** item b1
** item b2
* item3

I've got this:

Since this is the top result on Google:

If your connection works initially, but you begin seeing this error after many successful connections, it may be this issue.

In summary: if you open and close a connection, Windows reserves the TCP port for future use for some stupid reason. After doing this many times, it runs out of available ports.

The article gives a registry hack to fix the issue...

Here are my registry settings on XP/2003:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort 0xFFFF (DWORD)
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort\TcpTimedWaitDelay 60 (DWORD)

You need to create them. By default they don't exists.

On Vista/2008 you can use netsh to change it to something like:

netsh int ipv4 set dynamicport tcp start=10000 num=50000

...but the real solution is to use connection pooling, so that "opening" a connection really reuses an existing connection. Most frameworks do this automatically, but in my case the application was handling connections manually for some reason.

@Baba's answer is great. But you don't need to use explode because fputcsv takes an array as a parameter

For instance, if you have a three columns, four lines document, here's a more straight version:

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');

$user_CSV[0] = array('first_name', 'last_name', 'age');

// very simple to increment with i++ if looping through a database result 
$user_CSV[1] = array('Quentin', 'Del Viento', 34);
$user_CSV[2] = array('Antoine', 'Del Torro', 55);
$user_CSV[3] = array('Arthur', 'Vincente', 15);

$fp = fopen('php://output', 'wb');
foreach ($user_CSV as $line) {
    // though CSV stands for "comma separated value"
    // in many countries (including France) separator is ";"
    fputcsv($fp, $line, ',');
}
fclose($fp);

Instead of writing out values consider using fputcsv().

This may solve your problem immediately.

The right combination of Windows SDK Version and Platform Toolset needs to be selected Depends of course what toolset you have currently installed

Something I stumbled upon today for a DLL I knew was working fine with my VS2013 project, but not with VS2015:

Go to: Project -> XXXX Properties -> Build -> Uncheck "Prefer 32-bit"

This answer is way overdue and probably won't do any good, but if you. But I hope this will help somebody someday.

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

For me adding this in the web.config resolved the problem

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true" >
      <remove name="UrlRoutingModule"/>    
    </modules>
</system.webServer>

This is guesswork, but you may need to supply some or all of the floating point related switches for the link stage as well.

I've found Gengetopt to be quite useful - you specify the options you want with a simple configuration file, and it generates a .c/.h pair that you simply include and link with your application. The generated code makes use of getopt_long, appears to handle most common sorts of command line parameters, and it can save a lot of time.

A gengetopt input file might look something like this:

version "0.1"
package "myApp"
purpose "Does something useful."

# Options
option "filename" f "Input filename" string required
option "verbose" v "Increase program verbosity" flag off
option "id" i "Data ID" int required
option "value" r "Data value" multiple(1-) int optional 

Generating the code is easy and spits out cmdline.h and cmdline.c:

$ gengetopt --input=myApp.cmdline --include-getopt

The generated code is easily integrated:

#include <stdio.h>
#include "cmdline.h"

int main(int argc, char ** argv) {
  struct gengetopt_args_info ai;
  if (cmdline_parser(argc, argv, &ai) != 0) {
    exit(1);
  }
  printf("ai.filename_arg: %s\n", ai.filename_arg);
  printf("ai.verbose_flag: %d\n", ai.verbose_flag);
  printf("ai.id_arg: %d\n", ai.id_arg);
  int i;
  for (i = 0; i < ai.value_given; ++i) {
    printf("ai.value_arg[%d]: %d\n", i, ai.value_arg[i]);
  }
}

If you need to do any extra checking (such as ensuring flags are mutually exclusive), you can do this fairly easily with the data stored in the gengetopt_args_info struct.

Make sure your article:author data is a Facebook author URL. Unfortunately, that conflicts with what Pinterest is expecting. It's the best thing about standards, there are so many ways to implement them!

<meta property="article:author" content="https://www.facebook.com/mpatnode76">

But Pinterest wants to see something like this:

<meta property="article:author" content="Mike Patnode">

We ended up swapping the formats depending upon the user agent. Hopefully, that doesn't screw up your page cache. That fixed it for us.

Full disclosure. Found this here: https://surniaulula.com/2014/03/01/pinterest-articleauthor-incompatible-with-open-graph/

I had very similar problem for something like an hour, until I figured out what went wrong. My problem was, that I used SSL, instead of ssl. Check is case sensitive in the code. AlexV guided me to the source of the problem. That helo/ehlo -stuff seems irrelevant.

I met the same problem even using -ldl.

Besides this option, source files need to be placed before libraries, see undefined reference to `dlopen'.

@Sparr is right, but I guess you expected byte array like byte[] in C#. It's the same solution as Sparr did but instead of HEX you expected int presentation (range from 0 to 255) of each char. You can do as follows:

$byte_array = unpack('C*', 'The quick fox jumped over the lazy brown dog');
var_dump($byte_array);  // $byte_array should be int[] which can be converted
                        // to byte[] in C# since values are range of 0 - 255

By using var_dump you can see that elements are int (not string).

   array(44) {  [1]=>  int(84)  [2]=>  int(104) [3]=>  int(101) [4]=>  int(32)
[5]=> int(113)  [6]=>  int(117) [7]=>  int(105) [8]=>  int(99)  [9]=>  int(107)
[10]=> int(32)  [11]=> int(102) [12]=> int(111) [13]=> int(120) [14]=> int(32)
[15]=> int(106) [16]=> int(117) [17]=> int(109) [18]=> int(112) [19]=> int(101)
[20]=> int(100) [21]=> int(32)  [22]=> int(111) [23]=> int(118) [24]=> int(101)
[25]=> int(114) [26]=> int(32)  [27]=> int(116) [28]=> int(104) [29]=> int(101)
[30]=> int(32)  [31]=> int(108) [32]=> int(97)  [33]=> int(122) [34]=> int(121)
[35]=> int(32)  [36]=> int(98)  [37]=> int(114) [38]=> int(111) [39]=> int(119)
[40]=> int(110) [41]=> int(32)  [42]=> int(100) [43]=> int(111) [44]=> int(103) }

Be careful: the output array is of 1-based index (as it was pointed out in the comment)

This would work just fine, set the height to desired pixel

#inner-right{
            height: 100px;
            overflow:auto;
            }

I've implemented an immutable ECMAScript 6 solution based off of @Merc's answer over here:

const moveItemInArrayFromIndexToIndex = (array, fromIndex, toIndex) => {
  if (fromIndex === toIndex) return array;

  const newArray = [...array];

  const target = newArray[fromIndex];
  const inc = toIndex < fromIndex ? -1 : 1;

  for (let i = fromIndex; i !== toIndex; i += inc) {
    newArray[i] = newArray[i + inc];
  }

  newArray[toIndex] = target;

  return newArray;
};

The variable names can be shortened, just used long ones so that the code can explain itself.

You got an extra } to many as seen below:

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        } // <-- REMOVE THIS :)
    }, false);
};

A very good tool for those things is jsFiddle. I have created a fiddle with your invalid code and when clicking the TidyUp button it formats your code which makes it clearer if there are any possible mistakes with missing braces.

DEMO - Your code in a fiddle, have a play :)

Be sure you code sign on the line "any iOS SDK" and not "Debug/Distribution/Release"

Here is exactly what I did :

Code signing identity -> don't code sign
* Debug -> don't code sign
** any iOS SDK -> [my developer profile]
* Distribution -> don't code sign
** any iOS SDK -> [my AppStore profile]
* Release -> don't code sign
** any iOS SDK -> [my AdHoc profile]

When I put my profiles one level above (at Debug/Ditribution/Release), it doesn't work for some reason (bug ?).

Hope it helps some of us !

If you want to use a NSArray, you need an Objective-C class to put in it - hence the NSNumber requirement.

That said, Obj-C is still C, so you can use regular C arrays and hold regular ints instead of NSNumbers if you need to.

You may have to change the debugger port if your port is already used by another program. To do so:

• Run
• Edit Configurations
• Startup/Connection tab
• Debug
• Change the port here

Or, maybe in other versions:

• Run
• Edit Configurations
• Remote > Remote debug in the list on the left
• Configuration tab, Settings section
• Port: change the port here

If you are working with bytes you could use the builtin bytearray. If you are working with other integral types look at the builtin array.

Specifically understand that a list is not an array.

If, for example, you are trying to create a buffer for reading file contents into you could use bytearray as follows (there are better ways to do this but the example is valid):

with open(FILENAME, 'rb') as f:
    data = bytearray(os.path.getsize(FILENAME))
    f.readinto(data)

In this snippet the bytearray memory is preallocated with the fixed length of FILENAMEs size in bytes. This preallocation allows the use of the buffer protocol to more efficiently read the file into a mutable buffer without an array copy. There are yet better ways to do this but I believe this provides one answer to your question.

I checked some articles and find useful test script from this: http://www.sqlservercentral.com/Forums/Topic1480639-1292-1.aspx Then changed it to compare between NVARCHAR(10) vs NVARCHAR(4000) vs NVARCHAR(MAX) and I don't find speed difference when using specified numbers but when using MAX. You can test by yourself. Hope This help.

You could make usage of Array.prototype.indexOf. For that, we need to somewhat "cast" the HTMLNodeCollection into a true Array. For instance:

var nodes = Array.prototype.slice.call( document.getElementById('list').children );

Then we could just call:

nodes.indexOf( liNodeReference );

Example:

var nodes = Array.prototype.slice.call( document.getElementById('list').children ),_x000D_
    liRef = document.getElementsByClassName('match')[0];_x000D_
_x000D_
console.log( nodes.indexOf( liRef ) );

<ul id="list">_x000D_
    <li>foo</li>_x000D_
    <li class="match">bar</li>_x000D_
    <li>baz</li>    _x000D_
</ul>

I know I'm late on this one:

def convert_keys_to_string(dictionary):
    """Recursively converts dictionary keys to strings."""
    if not isinstance(dictionary, dict):
        return dictionary
    return dict((str(k), convert_keys_to_string(v)) 
        for k, v in dictionary.items())

A few comments:

import sun.misc.*; Don't do this. It is non-standard and not guaranteed to be the same between implementations. There are other libraries with Base64 conversion available.

byte[] encVal = c.doFinal(Data.getBytes()); You are relying on the default character encoding here. Always specify what character encoding you are using: byte[] encVal = c.doFinal(Data.getBytes("UTF-8")); Defaults might be different in different places.

As @thegrinner pointed out, you need to explicitly check the length of your byte arrays. If there is a discrepancy, then compare them byte by byte to see where the difference is creeping in.

Also make sure that you don't declare it an array and then try to assign something else to the array like a string, float, integer. I had that problem. If you do some echos of output I was seeing what I wanted the first time, but not after another pass of the same code.

It is standard matplotlib.pyplot:

...
import matplotlib.pyplot as plt
plt.ylim(10, 40)

Or simpler, as mwaskom comments below:

ax.set(ylim=(10, 40))

Open tmux configuration file with the following command:

vim ~/.tmux.conf

In the configuration file add the following line:

set -g history-limit 5000

Log out and log in again, start a new tmux windows and your limit is 5000 now.

Q: What is std::move?

A: std::move() is a function from the C++ Standard Library for casting to a rvalue reference.

Simplisticly std::move(t) is equivalent to:

static_cast<T&&>(t);

An rvalue is a temporary that does not persist beyond the expression that defines it, such as an intermediate function result which is never stored in a variable.

int a = 3; // 3 is a rvalue, does not exist after expression is evaluated
int b = a; // a is a lvalue, keeps existing after expression is evaluated

An implementation for std::move() is given in N2027: "A Brief Introduction to Rvalue References" as follows:

template <class T>
typename remove_reference<T>::type&&
std::move(T&& a)
{
    return a;
}

As you can see, std::move returns T&& no matter if called with a value (T), reference type (T&), or rvalue reference (T&&).

Q: What does it do?

A: As a cast, it does not do anything during runtime. It is only relevant at compile time to tell the compiler that you would like to continue considering the reference as an rvalue.

foo(3 * 5); // obviously, you are calling foo with a temporary (rvalue)

int a = 3 * 5;
foo(a);     // how to tell the compiler to treat `a` as an rvalue?
foo(std::move(a)); // will call `foo(int&& a)` rather than `foo(int a)` or `foo(int& a)`

What it does not do:

• Make a copy of the argument
• Call the copy constructor
• Change the argument object

Q: When should it be used?

A: You should use std::move if you want to call functions that support move semantics with an argument which is not an rvalue (temporary expression).

This begs the following follow-up questions for me:

• What is move semantics? Move semantics in contrast to copy semantics is a programming technique in which the members of an object are initialized by 'taking over' instead of copying another object's members. Such 'take over' makes only sense with pointers and resource handles, which can be cheaply transferred by copying the pointer or integer handle rather than the underlying data.

• What kind of classes and objects support move semantics? It is up to you as a developer to implement move semantics in your own classes if these would benefit from transferring their members instead of copying them. Once you implement move semantics, you will directly benefit from work from many library programmers who have added support for handling classes with move semantics efficiently.

• Why can't the compiler figure it out on its own? The compiler cannot just call another overload of a function unless you say so. You must help the compiler choose whether the regular or move version of the function should be called.

• In which situations would I want to tell the compiler that it should treat a variable as an rvalue? This will most likely happen in template or library functions, where you know that an intermediate result could be salvaged.

Be careful about the validation and etc, but the straight solution is this:

import json
the_dict = json.load(response)

From a practical enterprise perspective, the best practice is to make a mirrored copy of the database table in your database, and then just have a task/proc update it with delta's every hour.

Process is to clean up and then reinstall with the following commands:

rm -rf /usr/local/Cellar /usr/local/.git && brew cleanup
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install )"

Notes:

• Always check curl | bash (or ruby) commands before running them
• http://brew.sh/ (for installation notes)
• https://raw.githubusercontent.com/Homebrew/install/master/install (for clean up notes, see "Homebrew is already installed")

This answer may come a bit late but I have found an acceptable solution. My approach is a bit similar to @Mani one but I think mine is a bit more easy to understand.

Putting it into global hook and into the component itself are not ideal, global hook checks every request so you will need to write a lot of conditions to check if it should be 404 and window.location.href in the component creation is too late as the request has gone into the component already and then you take it out.

What I did is to have a dedicated url for 404 pages and have a path * that for everything that not found.

{ path: '/:locale/404', name: 'notFound', component: () => import('pages/Error404.vue') },
{ path: '/:locale/*', 
  beforeEnter (to) {
    window.location = `/${to.params.locale}/404`
  }
}

You can ignore the :locale as my site is using i18n so that I can make sure the 404 page is using the right language.

On the side note, I want to make sure my 404 page is returning httpheader 404 status code instead of 200 when page is not found. The solution above would just send you to a 404 page but you are still getting 200 status code. To do this, I have my nginx rule to return 404 status code on location /:locale/404

server {
    listen                      80;
    server_name                 localhost;

    error_page  404 /index.html;
    location ~ ^/.*/404$ {
      root   /usr/share/nginx/html;
      internal;
    }

    location / {
      root   /usr/share/nginx/html;
      index  index.html index.htm;
      try_files $uri $uri/ @rewrites;
    }

    location @rewrites {
      rewrite ^(.+)$ /index.html last;
    }

    location = /50x.html {
      root   /usr/share/nginx/html;
    }
}

The simplest solution is this:

$date    = '07/28/2010';
$newdate = date('Y-m-d', strtotime($date));

I recently used ez_setup.py as well and I did a tutorial on how to install it. The tutorial has snapshots and simple to follow. You can find it below:

I hope you find this helpful.

You can find the number of members in a Javascript array by using its length property:

var number = $scope.names.length;

^{Docs - Array.prototype.length}

In my case the image file had just been written to and needed to be flushed before opening, like so:

img_file.flush() 
img = Image.open(img_file.name))

Here's another way to do this:

- name: my command
  command: echo stuff
  when: "'groupname' not in group_names"

group_names is a magic variable as documented here: https://docs.ansible.com/ansible/latest/user_guide/playbooks_variables.html#accessing-information-about-other-hosts-with-magic-variables :

group_names is a list (array) of all the groups the current host is in.

as per the Chart js documentation page tick configuration section. you can format the value of each tick using the callback function. for example I wanted to change locale of displayed dates to be always German. in the ticks parts of the axis options

ticks: {
    callback: function(value) { 
        return new Date(value).toLocaleDateString('de-DE', {month:'short', year:'numeric'}); 
    },
},

Note that according to the CSS3 spec, you do NOT have to wrap your layout in a table-style element. The browser will infer the existence of containing elements if they do not exist.

Using the fileProvider is the way to go. But you can use this simple workaround:

WARNING: It will be fixed in next Android release - https://issuetracker.google.com/issues/37122890#comment4

replace:

startActivity(intent);

by

startActivity(Intent.createChooser(intent, "Your title"));

I did it like below. Not the best way i think, but it works :)

    Connection c = DriverManager.getConnection("jdbc:postgresql://....");
    PreparedStatement s = c.prepareStatement("select * from " + tabName + " where id > ? order by id");
    s.setMaxRows(100);
    int lastId = 0;
    for (;;) {
        s.setInt(1, lastId);
        ResultSet rs = s.executeQuery();

        int lastIdBefore = lastId;
        while (rs.next()) {
            lastId = Integer.parseInt(rs.getObject(1).toString());
            // ...
        }

        if (lastIdBefore == lastId) {
            break;
        }
    }

We can have three nodes previous,current and next.

public void reverseLinkedlist()
{
    /*
     * Have three nodes i.e previousNode,currentNode and nextNode
 When currentNode is starting node, then previousNode will be null
 Assign currentNode.next to previousNode to reverse the link.
 In each iteration move currentNode and previousNode by  1 node.
     */

    Node previousNode = null;
    Node currentNode = head;
    while (currentNode != null) 
    {
        Node nextNode = currentNode.next;
        currentNode.next = previousNode;
        previousNode = currentNode;
        currentNode = nextNode;
    }
    head = previousNode;
}

It will ask for the password the first time only. It will not ask for password again, unless the password is changed, etc.

If you have a build.gradle.kts written in Kotlin DSL you can print test results with (I was developing a kotlin multi-platform project, with no "java" plugin applied):

tasks.withType<AbstractTestTask> {
    afterSuite(KotlinClosure2({ desc: TestDescriptor, result: TestResult ->
        if (desc.parent == null) { // will match the outermost suite
            println("Results: ${result.resultType} (${result.testCount} tests, ${result.successfulTestCount} successes, ${result.failedTestCount} failures, ${result.skippedTestCount} skipped)")
        }
    }))
}

Very weird, but I got this error when I made a typo in the my.cnf file.
So it had nothing to do with the user directive not defined or not running as root-user.

My mistake was:

bind=192.168.1.2

instead of

bind-address=192.168.1.2

You can clear out their values by just setting value to an empty string:

var1.value = '';
var2.value = '';

From Wikipedia:

Applications implementing common services often use specifically reserved, well-known port numbers for receiving service requests from client hosts. This process is known as listening and involves the receipt of a request on the well-known port and reestablishing one-to-one server-client communications on another private port, so that other clients may also contact the well-known service port. The well-known ports are defined by convention overseen by the Internet Assigned Numbers Authority (IANA).

So as others mentioned, it's a convention.

I think the best first approach is to make sure to turn on detailed error messages via your web.config file, like this:

<configuration>
    <system.webServer>
        <httpErrors errorMode="Detailed"></httpErrors>
    </system.webServer>
</configuration>

After doing this, you should get a more detailed error message from the server.

In my particular case, the more detailed error pointed out that my <defaultDocument> section of the web.config file was not allowed at the folder level where I'd placed my web.config. It said

This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false". "

There are many ways to get a page from the command line... but it also depends if you want the code source or the page itself:

If you need the code source:

with curl:

curl $url

with wget:

wget -O - $url

but if you want to get what you can see with a browser, lynx can be useful:

lynx -dump $url

I think you can find so many solutions for this little problem, maybe you should read all man pages for those commands. And don't forget to replace $url by your URL :)

Good luck :)

You should have a look at numpy if you do matrix manipulation. This is a module mainly written in C, which will be much faster than programming in pure python. Here is an example of how to invert a matrix, and do other matrix manipulation.

from numpy import matrix
from numpy import linalg
A = matrix( [[1,2,3],[11,12,13],[21,22,23]]) # Creates a matrix.
x = matrix( [[1],[2],[3]] )                  # Creates a matrix (like a column vector).
y = matrix( [[1,2,3]] )                      # Creates a matrix (like a row vector).
print A.T                                    # Transpose of A.
print A*x                                    # Matrix multiplication of A and x.
print A.I                                    # Inverse of A.
print linalg.solve(A, x)     # Solve the linear equation system.

You can also have a look at the array module, which is a much more efficient implementation of lists when you have to deal with only one data type.

Am adding this answer for the purpose of those who google about this..

There was an episode of DevBytes (ListView Cell Dragging and Rearranging) recently which explains how to do this

You can find it here also the sample code is available here.

What this code basically does is that it creates a dynamic listview by the extension of listview that supports cell dragging and swapping. So that you can use the DynamicListView instead of your basic ListView and that's it you have implemented a ListView with Drag and Drop.

Hi, try this solution. Simple use php array map

function myfunction($value)
{
 return strtolower($value);
}

$new_array = ["Value1","Value2","Value3" ];
print_r(array_map("myfunction",$new_array ));

Output Array ( [0] => value1 [1] => value2 [2] => value3 )

The xpath() function does not return a string. It returns an array with XML elements (of type SimpleXMLElement), which may be casted to a string.

if (count($message)) {
   if (strlen((string)$message[0]) < 141) {
      echo "There Are No Contests.";
   }
   else if(strlen((string)$message[0]) > 142) {
      echo "There is One Active Contest.";
   }
}

In case you want to add years to specific date besides today's date using either years, or months, or days. You can do the following

var christmas2000 = new Date(2000, 12, 25); 
christmas2000.setFullYear(christmas2000.getFullYear() + 5); // using year: next 5 years
christmas2000.setFullYear(christmas2000.getMonth() + 24); // using months: next 24 months
christmas2000.setFullYear(christmas2000.getDay() + 365); // using days: next 365 months

Use var instead of int for your clicks variable generation and onClick instead of click as your function name:

var clicks = 0;

function onClick() {
  clicks += 1;
  document.getElementById("clicks").innerHTML = clicks;
};

<button type="button" onClick="onClick()">Click me</button>
<p>Clicks: <a id="clicks">0</a></p>

In JavaScript variables are declared with the var keyword. There are no tags like int, bool, string... to declare variables. You can get the type of a variable with 'typeof(yourvariable)', more support about this you find on Google.

And the name 'click' is reserved by JavaScript for function names so you have to use something else.

Maybe use LaTeX and try something like this

\documentclass[a4paper]{article}
\usepackage[3D]{movie15}
\usepackage{hyperref}
\begin{document}
\includemovie[
    poster,
    toolbar, 
    3Daac=60.000000, 3Droll=0.000000, 3Dc2c=0.000000 2.483000 0.000000,     3Droo=2.483000, 3Dcoo=0.000000 0.000000 0.000000,
    3Dlights=CAD,
]{\linewidth}{\linewidth}{Bob.u3d}
\end{document}

where Bob3d.u3d is a sample virtual reality file I had. This works (or did) for movies, and I expect it might work for gifs too.

Another approach

=CONCATENATE("Age as of ", TEXT(TODAY(),"dd-mmm-yyyy"))

This will return Age as of 06-Aug-2013

Important to point out, as others have, MySQL or MariaDB use a different syntax. Also it supports a very convenient USING syntax (in contrast to T/SQL). Also INNER JOIN is synonymous with JOIN. Therefor the query in the original question would be best implemented in MySQL thusly:

UPDATE
    Some_Table AS Table_A

JOIN
    Other_Table AS Table_B USING(id)

SET
    Table_A.col1 = Table_B.col1,
    Table_A.col2 = Table_B.col2

WHERE
    Table_A.col3 = 'cool'

I've not seen the a solution to the asked question in the other answers, hence my two cents. (tested on PHP 7.4.0 MariaDB 10.4.10)

Two steps works fine:

create table bu_x as (select a,b,c,d from x ) WITH no data;

insert into bu_x (a,b,c,d) select select a,b,c,d from x ;

If the value is hardcoded in the source of the page using the value attribute then you can

$('#attached_docs :input[value="123"]').remove();

If you want to target elements that have a value of 123, which was set by the user or programmatically then use EDIT works both ways ..

or

$('#attached_docs :input').filter(function(){return this.value=='123'}).remove();

demo http://jsfiddle.net/gaby/RcwXh/2/

The only way is to use a formula or to format cells. The method i will use will be the following: Add another column next to these values. Then use the following formula:

=HOUR(A1)*60+MINUTE(A1)+SECOND(A1)/60

one example more:

HTML link:

<a href="#featured" class="scrollTo">Learn More</a>

JS:

  $(".scrollTo").on('click', function(e) {
     e.preventDefault();
     var target = $(this).attr('href');
     $('html, body').animate({
       scrollTop: ($(target).offset().top)
     }, 2000);
  });

HTML anchor:

  <div id="featured">My content here</div>

As pointed out by Aaron Hall's comment:

Since you can't subclass NoneType and since None is a singleton, isinstance should not be used to detect None - instead you should do as the accepted answer says, and use is None or is not None.

Original Answer:

The simplest way however, without the extra line in addition to cardamom's answer is probably:
isinstance(x, type(None))

So how can I question a variable that is a NoneType? I need to use if method

Using isinstance() does not require an is within the if-statement:

if isinstance(x, type(None)): 
    #do stuff

Additional information
You can also check for multiple types in one isinstance() statement as mentioned in the documentation. Just write the types as a tuple.

isinstance(x, (type(None), bytes))

I would handle this in the parent form. You can notify the other form that it needs to modify itself through an event.

Here's a less verbose solution provided by Django:

<script type="text/javascript">
// using jQuery
var csrftoken = jQuery("[name=csrfmiddlewaretoken]").val();

function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
// set csrf header
$.ajaxSetup({
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
            xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
    }
});

// Ajax call here
$.ajax({
    url:"{% url 'members:saveAccount' %}",
    data: fd,
    processData: false,
    contentType: false,
    type: 'POST',
    success: function(data) {
        alert(data);
        }
    });
</script>

Child Component

Use this.$emit('event_name') to send an event to the parent component.

Parent Component

In order to listen to that event in the parent component, we do v-on:event_name and a method (ex. handleChange) that we want to execute on that event occurs

Done :)

Use aggregation on name and get name with count > 1:

db.collection.aggregate([
    {"$group" : { "_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"_id" :{ "$ne" : null } , "count" : {"$gt": 1} } }, 
    {"$project": {"name" : "$_id", "_id" : 0} }
]);

To sort the results by most to least duplicates:

db.collection.aggregate([
    {"$group" : { "_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"_id" :{ "$ne" : null } , "count" : {"$gt": 1} } }, 
    {"$sort": {"count" : -1} },
    {"$project": {"name" : "$_id", "_id" : 0} }     
]);

To use with another column name than "name", change "$name" to "$column_name"

$dbh = new PDO('pgsql:host=localhost;port=5432;dbname=###;user=###;password=##');

For PDO type connection uncomment

extension=php_pdo_pgsql.dll and comment with

;extension=php_pgsql.dll

$dbh = pg_connect("host=localhost dbname=### user=### password=####");

For pgconnect type connection comment

;extension=php_pdo_pgsql.dll and uncomment

extension=php_pgsql.dll

Both the connections should work.

The Visual jQuery site has some great examples of jQuery's array functionality. (Click "Utilities" on the left-hand tab, and then "Array and Object operations".)

@Ahmed

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".

Sub test()
    dbWb = Application.ActiveWorkbook.FullName
    dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2"  'Data2 is a named range


sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh

Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command

dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon

dbCommand.CommandText = sCommand
dbCommand.Execute

dbCon.Close


End Sub

Great answers from a couple of years ago. Now Bitbucket has made it easier.

Tag the Commit you want to download (as mentioned in answer by Rudy Matela).

Then head over to Downloads and click the "Tags" tab and you'll get multiple options for download.

We use AttachedCommandBehavior for this. You can attach any event to a command on your view model avoiding any code behind.

We use it throughout our solution and have almost zero code behind

You must use an integer value for the CURLOPT_SSLVERSION value, not a string as listed above

Try this:

curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 6); //Integer NOT string TLS v1.2

http://php.net/manual/en/function.curl-setopt.php

value should be an integer for the following values of the option parameter: CURLOPT_SSLVERSION

One of

CURL_SSLVERSION_DEFAULT (0)
CURL_SSLVERSION_TLSv1 (1)
CURL_SSLVERSION_SSLv2 (2)
CURL_SSLVERSION_SSLv3 (3)
CURL_SSLVERSION_TLSv1_0 (4)
CURL_SSLVERSION_TLSv1_1 (5)
CURL_SSLVERSION_TLSv1_2 (6).

Just check for

if(table.rows[0][0] == null)
{
     //Whatever I want to do
}

or you could

if(t.Rows[0].IsNull(0))
{
     //Whatever I want to do
}

Do adb remount. And then try adb shell

I understand that you want the Widget2 sharing the bottom border with the contents div. Try adding

style="position: relative; bottom: 0px"

to your Widget2 tag. Also try:

style="position: absolute; bottom: 0px"

if you want to snap your widget to the bottom of the screen.

I am a little rusty with CSS, perhaps the correct style is "margin-bottom: 0px" instead "bottom: 0px", give it a try. Also the pull-right class seems to add a "float=right" style to the element, and I am not sure how this behaves with "position: relative" and "position: absolute", I would remove it.

If you are making your text view width and height to wrap content then you have to manage it's position via layout gravity according to the parent supported attributes. Else you can do.

<TextView  
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:gravity="center"/> 

This partly depends on what you want to happen if you run into duplicates. For instance, you could do:

var result = dictionaries.SelectMany(dict => dict)
                         .ToDictionary(pair => pair.Key, pair => pair.Value);

That will throw an exception if you get any duplicate keys.

EDIT: If you use ToLookup then you'll get a lookup which can have multiple values per key. You could then convert that to a dictionary:

var result = dictionaries.SelectMany(dict => dict)
                         .ToLookup(pair => pair.Key, pair => pair.Value)
                         .ToDictionary(group => group.Key, group => group.First());

It's a bit ugly - and inefficient - but it's the quickest way to do it in terms of code. (I haven't tested it, admittedly.)

You could write your own ToDictionary2 extension method of course (with a better name, but I don't have time to think of one now) - it's not terribly hard to do, just overwriting (or ignoring) duplicate keys. The important bit (to my mind) is using SelectMany, and realising that a dictionary supports iteration over its key/value pairs.

My answer might be late for this post. It can be achieved through inline css within anchor tag only.

<a [routerLink]="['/user']" [style.pointer-events]="isDisabled ?'none':'auto'">click-label</a>

Considering isDisabled is a property in component which can be true or false.

Show HTML code, as-is, using the (obsolete) <xmp> tag:

_x000D_

_x000D_

<xmp>
<div>
  <input placeholder='write something' value='test'>
</div>
</xmp>

_x000D_

_x000D_

_x000D_

It is very sad this tag has been deprecated, but it does still works on browsers, it it is a bad-ass tag. no need to escape anything inside it. What a joy!

Show HTML code, as-is, using the <textarea> tag:

<textarea readonly rows="4" style="background:none; border:none; resize:none; outline:none; width:100%;">
<div>
  <input placeholder='write something' value='test'>
</div>
</textarea>

Sometimes spaces in path create a problem. You can add e.g. -vm C:\progra~1\Java\jre1.8.0_112\bin\javaw.exe

For a simple add/subtract hour/minute function in javascript, try this:

function getTime (addHour, addMin){
    addHour = (addHour?addHour:0);
    addMin = (addMin?addMin:0);
    var time = new Date(new Date().getTime());
    var AM = true;
    var ndble = 0;
    var hours, newHour, overHour, newMin, overMin;
    //change form 24 to 12 hour clock
    if(time.getHours() >= 13){
        hours = time.getHours() - 12;
        AM = (hours>=12?true:false);
    }else{
        hours = time.getHours();
        AM = (hours>=12?false:true);
    }
    //get the current minutes
    var minutes = time.getMinutes();
    // set minute
    if((minutes+addMin) >= 60 || (minutes+addMin)<0){
        overMin = (minutes+addMin)%60;
        overHour = Math.floor((minutes+addMin-Math.abs(overMin))/60);
        if(overMin<0){
            overMin = overMin+60;
            overHour = overHour-Math.floor(overMin/60);
        }
        newMin = String((overMin<10?'0':'')+overMin);
        addHour = addHour+overHour;
    }else{
        newMin = minutes+addMin;
        newMin = String((newMin<10?'0':'')+newMin);
    }
    //set hour
    if(( hours+addHour>=13 )||( hours+addHour<=0 )){
        overHour = (hours+addHour)%12;
        ndble = Math.floor(Math.abs((hours+addHour)/12));
        if(overHour<=0){
            newHour = overHour+12;
            if(overHour == 0){
                ndble++;
            }
        }else{
            if(overHour ==0 ){
                newHour = 12;
                ndble++;
            }else{
                ndble++;
                newHour = overHour;
            }
        }
        newHour = (newHour<10?'0':'')+String(newHour);
        AM = ((ndble+1)%2===0)?AM:!AM;
    }else{
        AM = (hours+addHour==12?!AM:AM);
        newHour = String((Number(hours)+addHour<10?'0':'')+(hours+addHour));
    }
    var am = (AM)?'AM':'PM';
    return new Array(newHour, newMin, am);
};

This can be used without parameters to get the current time

getTime();

or with parameters to get the time with the added minutes/hours

getTime(1,30); // adds 1.5 hours to current time
getTime(2);    // adds 2 hours to current time
getTime(0,120); // same as above

even negative time works

getTime(-1, -30); // subtracts 1.5 hours from current time

this function returns an array of

array([Hour], [Minute], [Meridian])

You normally wouldn't, since you wouldn't run it under *nix regardless. Do development in a user directory, and deploy afterwards to system directories.

The exception you get is telling you filedialog is not in your namespace. filedialog (and btw messagebox) is a tkinter module, so it is not imported just with from tkinter import *

>>> from tkinter import *
>>> filedialog
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
NameError: name 'filedialog' is not defined
>>> 

you should use for example:

>>> from tkinter import filedialog
>>> filedialog
<module 'tkinter.filedialog' from 'C:\Python32\lib\tkinter\filedialog.py'>
>>>

or

>>> import tkinter.filedialog as fdialog

or

>>> from tkinter.filedialog import askopenfilename

So this would do for your browse button:

from tkinter import *
from tkinter.filedialog import askopenfilename

            return

I recently had to build a fall back system which included any number of fallback images. Here's how I did it using a simple JavaScript function.

HTML

<img src="some_image.tiff"
    onerror="fallBackImg(this);"
    data-fallIndex="1"
    data-fallback1="some_image.png"
    data-fallback2="some_image.jpg">

JavaScript

function fallBackImg(elem){
    elem.onerror = null;
    let index = +elem.dataset.fallIndex;
    elem.src = elem.dataset[`fallback${index}`];
    index++;
    elem.dataset.fallbackindex = index;
}

I feel like it's a pretty lightweight way of handling many fallback images.

Summary of the answers

For understanding what is the best answer we can do some timing using the different solution. Unfortunately, the question was not well-posed so there are answers to different questions, here I try to point the answer to the same question. Given the array:

a = np.array([1, 3, 5, 6, 9, 10, 14, 15, 56])

The answer should be the indexes of the elements between a certain range, we assume inclusive, in this case, 6 and 10.

answer = (3, 4, 5)

Corresponding to the values 6,9,10.

To test the best answer we can use this code.

import timeit
setup = """
import numpy as np
import numexpr as ne

a = np.array([1, 3, 5, 6, 9, 10, 14, 15, 56])
# we define the left and right limit
ll = 6
rl = 10

def sorted_slice(a,l,r):
    start = np.searchsorted(a, l, 'left')
    end = np.searchsorted(a, r, 'right')
    return np.arange(start,end)
"""

functions = ['sorted_slice(a,ll,rl)', # works only for sorted values
'np.where(np.logical_and(a>=ll, a<=rl))[0]',
'np.where((a >= ll) & (a <=rl))[0]',
'np.where((a>=ll)*(a<=rl))[0]',
'np.where(np.vectorize(lambda x: ll <= x <= rl)(a))[0]',
'np.argwhere((a>=ll) & (a<=rl)).T[0]', # we traspose for getting a single row
'np.where(ne.evaluate("(ll <= a) & (a <= rl)"))[0]',]

functions2 = [
   'a[np.logical_and(a>=ll, a<=rl)]',
   'a[(a>=ll) & (a<=rl)]',
   'a[(a>=ll)*(a<=rl)]',
   'a[np.vectorize(lambda x: ll <= x <= rl)(a)]',
   'a[ne.evaluate("(ll <= a) & (a <= rl)")]',
]

Results

The results are reported in the following plot. On the top the fastest solutions. If instead of the indexes you want to extract the values you can perform the tests using functions2 but the results are almost the same.

Use Java script to change action url dynamically Works for me well

function chgAction( action_name )
{

 {% for data in sidebar_menu_data %}

     if( action_name== "ABC"){ document.forms.action = "/ABC/";
     }
     else if( action_name== "XYZ"){ document.forms.action = "/XYZ/";
     }

}

<form name="forms" method="post" action="<put default url>" onSubmit="return checkForm(this);">{% csrf_token %}

This request displays all active requests and all those requests that explicitly block active requests.

All these and other useful scripts are implemented as representations in the SRV database, which is distributed freely. For example, the first script came from the view [inf].[vBigQuery], and the second came from view [inf].[vRequests].

There are also various third-party solutions for query history. I use Query Manager from Dbeaver: and Query Execution History from SQL Tools, which is embedded in SSMS:

I had that problem too and I solve it by:

$today = date("Ymd");
$expire = str_replace('-', '', $row->expireDate); //from db

if(($today - $expire) > $NUMBER_OF_DAYS) 
{ 
    //do something; 
}

To answer this question it's critical whether the Java VM is in CLIENT or SERVER mode. You can specify "-client" or "-server" options. Otherwise java uses internal rules; basically win32 is always client and Linux is always server, but see the table here:

http://docs.oracle.com/javase/6/docs/technotes/guides/vm/server-class.html

Sun/Oracle jre6u18 doc says re client: the VM gets 1/2 of physical memory if machine has <= 192MB; 1/4 of memory if machine has <= 1Gb; max 256Mb. In my test on a 32bit WindowsXP system with 2Gb phys mem, Java allocated 256Mb, which agrees with the doc.

Sun/Oracle jre6u18 doc says re server: same as client, then adds confusing language: for 32bit JVM the default max is 1Gb, and for 64 bit JVM the default is 32Gb. In my test on a 64bit linux machine with 8Gb physical, Java allocates 2Gb, which is 1/4 of physical; on a 64bit linux machine with 128Gb physical Java allocates 32Gb, again 1/4 of physical.

Thanks to this SO post for guiding me:

Definition of server-class machine changed recently?

element = random.choice(myList)
if element:
    # element contains text
else:
    # element is empty ''

Use size attribute of <select>;

The server-side processing language in use (eg PHP, .net, etc) isn't specified, but if it's PHP, grab the required number (or all the records) and instead of randomising in the query use PHP's shuffle function. I don't know if .net has an equivalent function but if it does then use that if you're using .net

ORDER BY RAND() can have quite a performance penalty, depending on how many records are involved.

Not sure if this was posted before but I got this working with WebClient. i read the documentation for the WebClient. A key point they make is

If the BaseAddress property is not an empty string ("") and address does not contain an absolute URI, address must be a relative URI that is combined with BaseAddress to form the absolute URI of the requested data. If the QueryString property is not an empty string, it is appended to address.

So all I did was wc.QueryString.Add("source", generatedImage) to add the different query parameters and somehow it matches the property name with the image I uploaded. Hope it helps

    public void postImageToFacebook(string generatedImage, string fbGraphUrl)
    {
        WebClient wc = new WebClient();
        byte[] bytes = System.IO.File.ReadAllBytes(generatedImage);

        wc.QueryString.Add("source", generatedImage);
        wc.QueryString.Add("message", "helloworld");

        wc.UploadFile(fbGraphUrl, generatedImage);

        wc.Dispose();

    }

Setting text color of navigation bar title to white in Swift version 4.2:

Just to add to the answers, it also happens when your API response includes

<?php{username: 'Some'}

which could be a case when your backend is using PHP.

You have to create a derived table for the distinct columns and then query the count from that table:

SELECT COUNT(*) 
FROM (SELECT DISTINCT column1,column2
      FROM  tablename  
      WHERE condition ) as dt

Here dt is a derived table.

A full outer join combines a left outer join and a right outer join. The result set returns rows from both tables where the conditions are met but returns null columns where there is no match.

A cross join is a Cartesian product that does not require any condition to join tables. The result set contains rows and columns that are a multiplication of both tables.

A magic number is a sequence of characters at the start of a file format, or protocol exchange. This number serves as a sanity check.

Example: Open up any GIF file, you will see at the very start: GIF89. "GIF89" being the magic number.

Other programs can read the first few characters of a file and properly identify GIFs.

The danger is that random binary data can contain these same characters. But it is very unlikely.

As for protocol exchange, you can use it to quickly identify that the current 'message' that is being passed to you is corrupted or not valid.

Magic numbers are still useful.

Use a for loop to iterate through your array. For each string, create a new option element, assign the string as its innerHTML and value, and then append it to the select element.

var cuisines = ["Chinese","Indian"];     
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisines[i];
    opt.value = cuisines[i];
    sel.appendChild(opt);
}

DEMO

UPDATE: Using createDocumentFragment and forEach

If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild operation so that the DOM only updates once, instead of n times.

var cuisines = ["Chinese","Indian"];     

var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();

cuisines.forEach(function(cuisine, index) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisine;
    opt.value = cuisine;
    fragment.appendChild(opt);
});

sel.appendChild(fragment);

Yes, this is an old question. But it's misleading, as this was the first result in my search, and both the answers aren't correct anymore.

You can change your Github account name at any time.

To do this, click your profile picture > Settings > Account Settings > Change Username.

Links to your repositories will redirect to the new URLs, but they should be updated on other sites because someone who chooses your abandoned username can override the links. Links to your profile page will be 404'd.

For more information, see the official help page.

And furthermore, if you want to change your username to something else, but that specific username is being taken up by someone else who has been completely inactive for the entire time their account has existed, you can report their account for name squatting.

Check you gradle settings, it may be set to Offline Work

In addition to kieran's answer, apparently, modern browsers have an Object.keys function. In this case, you could do this:

Object.keys(jsonArray).length;

You can use:

type text1.txt >> combine.txt
echo >> combine.txt
type text2.txt >> combine.txt

or something like this:

echo blah >> combine.txt
echo blah2 >> combine.txt
echo >> combine.txt
echo other >> combine.txt

If you don't want to commit, or want to commit later (commit message will still be prepared for you, which you can also edit):

git revert -n <commit>

You can install cygwin, which has rm as well as ls etc.

I also encountered this issue. Did the following and it got fixed.

1. Open your computer terminal (not VSCode terminal) and type node --version to ensure you have node installed. If not, then install node using nvm.
2. Then head to your bash file (eg .bashrc, .bash_profile, .profile) and add the PATH:

 [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm 
 [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

3. If you have multiple bash files, you ensure to add the PATH to all of them.
4. Restart your VSCode terminal and it should be fine.

in my case, i had failed to include the type attribute on my script tag.

<script type="text/jsx">

You want to use the array_key_exists function.

The below option works most of time and also for pasting later.

 "xnyy
x - buffer name
n - number of line to Yank - optional

The lines yanked will be stored in the buffer 'x'. It can be used anywhere in the edit.

To paste line(s) in the other file,

:e filename&location

Example: Type the below command in the current edit

:e /u/test/Test2.sh
and paste using "xP
P - before cursor
p - after cursor

Complete operation

open file 1 :

vi Test1.sh

a10yy

-Yanked 10 lines

-now open the second file from the current edit

*:e /u/test/Test2.sh*

-move the cursor to the line where you have to paste

*"ap*

--Lines from the buffer '*a*' will be copied after the current cursor pos

Following steps might be helpful (For linux users):

1. At first enter the postgres command prompt by following command:

   sudo -u postgres psql
   

2. Enter the database by this command (my database name is: maoss):

   \c maoss
   

3. Now enter the command for droping all tables:

   DROP SCHEMA public CASCADE;
   CREATE SCHEMA public;
   
   GRANT ALL ON SCHEMA public TO postgres;
   GRANT ALL ON SCHEMA public TO public;
   

You cannot session_start(); when your buffer has already been partly sent.

This mean, if your script already sent informations (something you want, or an error report) to the client, session_start() will fail.

rem out the @ECHO OFF and call your batch file redirectin ALL output to a log file..

Other than mentioned answers..I would like to add some other points.

Bias acts as our anchor. It's a way for us to have some kind of baseline where we don't go below that. In terms of a graph, think of like y=mx+b it's like a y-intercept of this function.

output = input times the weight value and added a bias value and then apply an activation function.

On Arduino 1.0, this compiles just fine:

class A
{
  public:
   int x;
   virtual void f() { x=1; }
};

class B : public A
{
  public:
    int y;
    virtual void f() { x=2; }
};


A *a;
B *b;
const int TEST_PIN = 10;

void setup()
{
   a=new A(); 
   b=new B();
   pinMode(TEST_PIN,OUTPUT);
}

void loop()
{
   a->f();
   b->f();
   digitalWrite(TEST_PIN,(a->x == b->x) ? HIGH : LOW);
}

I used Fittext on some of my projects and it looks like a good solution to a problem like this.

FitText makes font-sizes flexible. Use this plugin on your fluid or responsive layout to achieve scalable headlines that fill the width of a parent element.

Unfortunately, adding the javaee-(web)-api as a dependency doesn't give you the Javadoc or the Source to the Servlet Api to browse them from within the IDE. This is also the case for all other dependencies (JPA, EJB, ...) If you need the Servlet API sources/javadoc, you can add the following to your pom.xml (works at least for JBoss&Glassfish):

I completely removed the javaee-api from my dependencies and replaced it with the discrete parts (javax.ejb, javax.faces, ...) to get the sources and Javadocs for all parts of Java EE 6.

EDIT:

Here is the equivalent Glassfish dependency (although both dependencies should work, no matter what appserver you use).

With the latest versions of PowerShell, there is a new cmdlet, Test-NetConnection.

This cmdlet lets you, in effect, ping a port, like this:

Test-NetConnection -ComputerName <remote server> -Port nnnn

I know this is an old question, but if you hit this page (as I did) looking for this information, this addition may be helpful!

While unzipping will reveal the resources, the AndroidManifest.xml will be encoded. apktool can – among lots of other things – also decode this file.

To decode the application App.apk into the folder App, run

apktool decode App.apk App

apktool is not included in the official Android SDK, but available using most packet repositories.

Here's my angle on it, based on Hernaldo's, if you need to find files with names of a certain pattern, such as XML files that somewhere in their name contain a particular string:

// call this like so: GetXMLFiles("Platypus", "C:\\");
public static List<string> GetXMLFiles(string fileType, string dir)
{
    string dirName = dir; 
    var fileNames = new List<String>();
    try
    {
        foreach (string f in Directory.GetFiles(dirName))
        {
            if ((f.Contains(fileType)) && (f.Contains(".XML")))
            {
                fileNames.Add(f);
            }
        }
        foreach (string d in Directory.GetDirectories(dirName))
        {
            GetXMLFiles(fileType, d);
        }
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
    return fileNames;
}

To get the current directory, you can use this:

CD > tmpFile
SET /p myvar= < tmpFile
DEL tmpFile
echo test: %myvar%

It's using a temp-file though, so it's not the most pretty, but it certainly works! 'CD' puts the current directory in 'tmpFile', 'SET' loads the content of tmpFile.

Here is a solution for multiple lines with "array's":

@echo off

rem ---------
rem Obtain line numbers from the file
rem ---------

rem This is the file that is being read: You can replace this with %1 for dynamic behaviour or replace it with some command like the first example i gave with the 'CD' command.
set _readfile=test.txt

for /f "usebackq tokens=2 delims=:" %%a in (`find /c /v "" %_readfile%`) do set _max=%%a
set /a _max+=1
set _i=0
set _filename=temp.dat

rem ---------
rem Make the list
rem ---------

:makeList
find /n /v "" %_readfile% >%_filename%

rem ---------
rem Read the list
rem ---------

:readList
if %_i%==%_max% goto printList

rem ---------
rem Read the lines into the array
rem ---------
for /f "usebackq delims=] tokens=2" %%a in (`findstr /r "\[%_i%]" %_filename%`) do set _data%_i%=%%a
set /a _i+=1
goto readList

:printList
del %_filename%
set _i=1
:printMore
if %_i%==%_max% goto finished
set _data%_i%
set /a _i+=1
goto printMore

:finished

But you might want to consider moving to another more powerful shell or create an application for this stuff. It's stretching the possibilities of the batch files quite a bit.

You can simply set the status code of the response to 200 like the following

public ActionResult SomeMethod(parameters...)
{
   //others code here
   ...      
   Response.StatusCode = 200;
   return YourObject;  
}

std::queue<myclass*> that's it

It should be something like...

<xsl:if test="contains($hhref, '1234')">

(not tested)

There are a few other choices in case the Adobe ActiveX isn't what you're looking for (since Acrobat must be present on the user machine and you can't ship it yourself).

For creating the PDF preview, first have a look at some other discussions on the subject on StackOverflow:

• How can I take preview of documents?
• Get a preview jpeg of a pdf on windows?
• .NET open PDF in winform without external dependencies
• PDF Previewing and viewing

In the last two I talk about a few things you can try:

• You can get a commercial renderer (PDFViewForNet, PDFRasterizer.NET, ABCPDF, ActivePDF, XpdfRasterizer and others in the other answers...).
  Most are fairly expensive though, especially if all you care about is making a simple preview/thumbnails.

• In addition to Omar Shahine's code snippet, there is a CodeProject article that shows how to use the Adobe ActiveX, but it may be out of date, easily broken by new releases and its legality is murky (basically it's ok for internal use but you can't ship it and you can't use it on a server to produce images of PDF).

• You could have a look at the source code for SumatraPDF, an OpenSource PDF viewer for windows.

• There is also Poppler, a rendering engine that uses Xpdf as a rendering engine. All of these are great but they will require a fair amount of commitment to make make them work and interface with .Net and they tend to be be distributed under the GPL.

• You may want to consider using GhostScript as an interpreter because rendering pages is a fairly simple process.
  The drawback is that you will need to either re-package it to install it with your app, or make it a pre-requisite (or at least a part of your install process).
  It's not a big challenge, and it's certainly easier than having to massage the other rendering engines into cooperating with .Net.
  I did a small project that you will find on the Developer Express forums as an attachment.
  Be careful of the license requirements for GhostScript through.
  If you can't leave with that then commercial software is probably your only choice.

I would like to argue one point - that you cannot augment the original assembly - using Mono.Cecil you can inject [InternalsVisibleTo(...)] to the 3pty assembly. Note there might be legal implications - you're messing with 3pty assembly and technical implications - if the assembly has strong name you either need to strip it or re-sign it with different key.

 Install-Package Mono.Cecil

And the code like:

static readonly string[] s_toInject = {
  // alternatively "MyAssembly, PublicKey=0024000004800000... etc."
  "MyAssembly"
};

static void Main(string[] args) {
  const string THIRD_PARTY_ASSEMBLY_PATH = @"c:\folder\ThirdPartyAssembly.dll";

   var parameters = new ReaderParameters();
   var asm = ModuleDefinition.ReadModule(INPUT_PATH, parameters);
   foreach (var toInject in s_toInject) {
     var ca = new CustomAttribute(
       asm.Import(typeof(InternalsVisibleToAttribute).GetConstructor(new[] {
                      typeof(string)})));
     ca.ConstructorArguments.Add(new CustomAttributeArgument(asm.TypeSystem.String, toInject));
     asm.Assembly.CustomAttributes.Add(ca);
   }
   asm.Write(@"c:\folder-modified\ThirdPartyAssembly.dll");
   // note if the assembly is strongly-signed you need to resign it like
   // asm.Write(@"c:\folder-modified\ThirdPartyAssembly.dll", new WriterParameters {
   //   StrongNameKeyPair = new StrongNameKeyPair(File.ReadAllBytes(@"c:\MyKey.snk"))
   // });
}

Simply skip the error using .values at the end.

        } else if (el.val() === "MANUAL") {

        }

});

The sample mvcmusicstore.codeplex.com opened in vs2015 missed some references, one of them System.web.mvc.

The fix for this was to remove it from the references and to add a reference: choose Extentions under Assemblies, there you can find and add System.Web.Mvc.

(The other assemblies I added with the nuget packages.)

Here is a solution for reading - not writing - the extended properties based on what I found on this page and at help with shell32 objects.

To be clear this is a hack. It looks like this code will still run on Windows 10 but will hit on some empty properties. Previous version of Windows should use:

        var i = 0;
        while (true)
        {
            ...
            if (String.IsNullOrEmpty(header)) break;
            ...
            i++;

On Windows 10 we assume that there are about 320 properties to read and simply skip the empty entries:

    private Dictionary<string, string> GetExtendedProperties(string filePath)
    {
        var directory = Path.GetDirectoryName(filePath);
        var shell = new Shell32.Shell();
        var shellFolder = shell.NameSpace(directory);
        var fileName = Path.GetFileName(filePath);
        var folderitem = shellFolder.ParseName(fileName);
        var dictionary = new Dictionary<string, string>();
        var i = -1;
        while (++i < 320)
        {
            var header = shellFolder.GetDetailsOf(null, i);
            if (String.IsNullOrEmpty(header)) continue;
            var value = shellFolder.GetDetailsOf(folderitem, i);
            if (!dictionary.ContainsKey(header)) dictionary.Add(header, value);
            Console.WriteLine(header +": " + value);
        }
        Marshal.ReleaseComObject(shell);
        Marshal.ReleaseComObject(shellFolder);
        return dictionary;
    }

As mentioned you need to reference the Com assembly Interop.Shell32.

If you get an STA related exception, you will find the solution here:

Exception when using Shell32 to get File extended properties

I have no idea what those properties names would be like on a foreign system and couldn't find information about which localizable constants to use in order to access the dictionary. I also found that not all the properties from the Properties dialog were present in the dictionary returned.

BTW this is terribly slow and - at least on Windows 10 - parsing dates in the string retrieved would be a challenge so using this seems to be a bad idea to start with.

On Windows 10 you should definitely use the Windows.Storage library which contains the SystemPhotoProperties, SystemMusicProperties etc. https://docs.microsoft.com/en-us/windows/uwp/files/quickstart-getting-file-properties

And finally, I posted a much better solution that uses WindowsAPICodePack there

There's surprisingly simple way of reading resource by string:

ResourceNamespace.ResxFileName.ResourceManager.GetString("ResourceKey")

It's clean and elegant solution for reading resources by keys where "dot notation" cannot be used (for instance when resource key is persisted in the database).

try the array_count_values() function

<?php
$array = array(1, "hello", 1, "world", "hello");
print_r(array_count_values($array));
?>

output:

Array
(
    [1] => 2
    [hello] => 2
    [world] => 1
)

http://php.net/manual/en/function.array-count-values.php

Here's an example in C on Linux. That's if, you're on Linux and don't mind doing this small bit in ANSI C.

#include <dirent.h>

DIR *dpdf;
struct dirent *epdf;

dpdf = opendir("./");
if (dpdf != NULL){
   while (epdf = readdir(dpdf)){
      printf("Filename: %s",epdf->d_name);
      // std::cout << epdf->d_name << std::endl;
   }
}
closedir(dpdf);

I think this would work...

create table atable
(
  atableID int IDENTITY(1, 1) PRIMARY KEY CLUSTERED,
  Modified datetime DEFAULT ((0))
)

Edit: This is wrong...The minimum SQL DateTime Value is 1/1/1753. My solution provides a datetime = 1/1/1900 00:00:00. Other answers have the correct minimum date...

The default string representation for a dictionary seems to be just right:

>>> a={3: 'foo', 17: 'bar' }
>>> a
{17: 'bar', 3: 'foo'}
>>> print a
{17: 'bar', 3: 'foo'}
>>> print "a=", a
a= {17: 'bar', 3: 'foo'}

Not sure if you can get at the "variable name", since variables in Python are just labels for values. See this question.

try

jdbc:sqlserver://hostname:port;databaseName=TEST

It worked for me after adding colon before port number instead of a comma

You don't need to wrap it in a list with [..], just provide the subselection of the columns index:

df.drop(df.columns[[1, 69]], axis=1, inplace=True)

as the index object is already regarded as list-like.

The functional way of achieving this is to unzip the list using:

sample = [(2, 9), (2, 9), (8, 9), (10, 9), (23, 26), (1, 9), (43, 44)]
first,snd = zip(*sample)
print(first,snd)

(2, 2, 8, 10, 23, 1, 43) (9, 9, 9, 9, 26, 9, 44)

The best I came up with is using the unsrt style, which seems to be a tweaked plain style. i.e.

\bibliographystyle{unsrt}
\bibliography{bibliography}

However what if my style is not the default?

sed (and its ilk) are contained within several packages of Unix commands.

• Cygwin works but is gigantic.
• UnxUtils is much slimmer.
• GnuWin32 is another port that works.
• Another alternative is AT&T Research's UWIN system.
• MSYS from MinGw is yet another option.
• Windows Subsystem for Linux is a most "native" option, but it's not installed on Windows by default; it has sed, grep etc. out of the box, though.
• https://github.com/mbuilov/sed-windows offers recent 4.3 and 4.4 versions, which support -z option unlike listed upper ports

If you don't want to install anything and your system ain't a Windows Server one, then you could use a scripting language (VBScript e.g.) for that. Below is a gross, off-the-cuff stab at it. Your command line would look like

cscript //NoLogo sed.vbs s/(oldpat)/(newpat)/ < inpfile.txt > outfile.txt

where oldpat and newpat are Microsoft vbscript regex patterns. Obviously I've only implemented the substitute command and assumed some things, but you could flesh it out to be smarter and understand more of the sed command-line.

Dim pat, patparts, rxp, inp
pat = WScript.Arguments(0)
patparts = Split(pat,"/")
Set rxp = new RegExp
rxp.Global = True
rxp.Multiline = False
rxp.Pattern = patparts(1)
Do While Not WScript.StdIn.AtEndOfStream
  inp = WScript.StdIn.ReadLine()
  WScript.Echo rxp.Replace(inp, patparts(2))
Loop

The performance is almost a 100% identical. You can check this out by opening the class in Reflector.net

This is the This indexer:

public TValue this[TKey key]
{
    get
    {
        int index = this.FindEntry(key);
        if (index >= 0)
        {
            return this.entries[index].value;
        }
        ThrowHelper.ThrowKeyNotFoundException();
        return default(TValue);
    }
    set
    {
        this.Insert(key, value, false);
    }
}

And this is the Add method:

public void Add(TKey key, TValue value)
{
    this.Insert(key, value, true);
}

I won't post the entire Insert method as it's rather long, however the method declaration is this:

private void Insert(TKey key, TValue value, bool add)

And further down in the function, this happens:

if ((this.entries[i].hashCode == num) && this.comparer.Equals(this.entries[i].key, key))
{
    if (add)
    {
        ThrowHelper.ThrowArgumentException(ExceptionResource.Argument_AddingDuplicate);
    }

Which checks if the key already exists, and if it does and the parameter add is true, it throws the exception.

So for all purposes and intents the performance is the same.

Like a few other mentions, it's all about whether you need the check, for attempts at adding the same key twice.

Sorry for the lengthy post, I hope it's okay.

It doesn't have to be complicated.

$(document).on('click', function() {
    $("#menu:not(:hover)").hide();
});

As mentioned in my earlier answer, you can use RegExp.exec() to iterate over all matches and count each occurrence; the advantage is limited to memory only, because on the whole it's about 20% slower than using String.match().

var re = /\s/g,
count = 0;

while (re.exec(text) !== null) {
    ++count;
}

return count;

There are already very good answers here, but in some other cases (not this in particular) using map could be the "only" solution.

Specially when we want to use regexps, other than the standard ones.

For this case it would look like this:

 $('.myClass').filter(function(index, elem) {
    var jElem = $(elem);

    return jElem.closest('#Create').length > 0 || 
           jElem.closest('#Edit').length > 0;

}).plugin(...);

As I said before, here this solution could be useless, but for further problems, is a very good option

There are some great answers mentioned here. Another approach you could take would be to use some free SDKs available online like Atooma, tranql and Neura, that can be integrated with your Android application (it takes less than 20 min to integrate). Along with giving you the accurate location of your user, it can also give you good insights about your user’s activities. Also, some of them consume less than 1% of your battery

One minor difference is what they convert of undefined or null,

Number() Or Number(null) // returns 0

while

parseInt() Or parseInt(null) // returns NaN

Using paste command:

paste -d, -s file

/data/data/"your app package name " 

but you wont able to read that unless you have a rooted device

Here's how to do this with Pandas FWIW:

import pandas as pd
pd.date_range("1990/04/03", "2014/12/31", freq="MS")

DatetimeIndex(['1990-05-01', '1990-06-01', '1990-07-01', '1990-08-01',
               '1990-09-01', '1990-10-01', '1990-11-01', '1990-12-01',
               '1991-01-01', '1991-02-01',
               ...
               '2014-03-01', '2014-04-01', '2014-05-01', '2014-06-01',
               '2014-07-01', '2014-08-01', '2014-09-01', '2014-10-01',
               '2014-11-01', '2014-12-01'],
              dtype='datetime64[ns]', length=296, freq='MS')

Notice it starts with the month after the given start date.

You can also use -match against a Regular expression. Ex:

if ($dbUserName -match ".{8}" )

}

Also if you're like me and like your curly braces to be in the same horizontal position for your code blocks, you can put that on a new line, since it's expecting a code block it will look on next line. In some commands where the first curly brace has to be in-line with your command, you can use a grave accent marker (`) to tell powershell to treat the next line as a continuation.

In 2020, iOS13, xCode 11.3. What is working for Objective-C is:

#import "AppDelegate.h"

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];

It's working for me, i hope the same to you! :D

FORCE_INDEX is going to be deprecated after MySQL 8:

Thus, you should expect USE INDEX, FORCE INDEX, and IGNORE INDEX to be deprecated in 
a future release of MySQL, and at some time thereafter to be removed altogether.

https://dev.mysql.com/doc/refman/8.0/en/index-hints.html

You should be using JOIN_INDEX, GROUP_INDEX, ORDER_INDEX, and INDEX instead, for v8.

not found on the java.library.path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib

The native lib is expected in one of the following locations

/usr/java/packages/lib/amd64
/usr/lib64
/lib64
/lib
/usr/lib

and not in

tomcat/lib

The files in tomcat/lib are all jar file and are added by tomcat to the classpath so that they are available to your application.

The native lib is needed by tomcat to perform better on the platform it is installed on and thus cannot be a jar, for linux it could be a .so file, for windows it could be a .dll file.

Just download the native library for your platform and place it in the one of the locations tomcat is expecting it to be.

Note that you are not required to have this lib for development/test purposes. Tomcat runs just fine without it.

org.apache.catalina.startup.Catalina start INFO: Server startup in 2882 ms

EDIT

The output you are getting is very normal, it's just some logging outputs from tomcat, the line right above indicates that the server correctly started and is ready for operating.

If you are troubling with running your servlet then after the run on sever command eclipse opens a browser window (embeded (default) or external, depends on your config). If nothing shows on the browser, then check the url bar of the browser to see whether your servlet was requested or not.

It should be something like that

http://localhost:8080/<your-context-name>/<your-servlet-name>

EDIT 2

Try to call your servlet using the following url

http://localhost:8080/com.filecounter/FileCounter

Also each web project has a web.xml, you can find it in your project under WebContent\WEB-INF.

It is better to configure your servlets there using servlet-name servlet-class and url-mapping. It could look like that:

  <servlet>
    <description></description>
    <display-name>File counter - My first servlet</display-name>
    <servlet-name>file_counter</servlet-name>
    <servlet-class>com.filecounter.FileCounter</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>file_counter</servlet-name>
    <url-pattern>/FileFounter</url-pattern>
  </servlet-mapping>

In eclipse dynamic web project the default context name is the same as your project name.

http://localhost:8080/<your-context-name>/FileCounter

will work too.

You can do this:

CSS:

#container {
    height:175px;
}

#container h3{
    position:absolute;
    bottom:0;
    left:0;
}

Then in HTML:

<div class="row">
    <div class="col-sm-6">
        <img src="//placehold.it/600x300" alt="Logo" />
    </div>
    <div id="container" class="col-sm-6">
        <h3>Some Text</h3>
    </div>
</div>

EDIT: add the <

Grep DOES NOT use "wildcards" for search – that's shell globbing, like *.jpg. Grep uses "regular expressions" for pattern matching. While in the shell '*' means "anything", in grep it means "match the previous item zero or more times".

More information and examples here: http://www.regular-expressions.info/reference.html

To answer of your question - you can find files matching some pattern with grep:

find /somedir -type f -print | grep 'LMN2011' # that will show files whose names contain LMN2011

Then you can search their content (case insensitive):

find /somedir -type f -print | grep -i 'LMN2011' | xargs grep -i 'LMN20113456'

If the paths can contain spaces, you should use the "zero end" feature:

find /somedir -type f -print0 | grep -iz 'LMN2011' | xargs -0 grep -i 'LMN20113456'

Use the following command:

lsof -n -i4TCP:8080 | awk '{print$2}' | xargs kill -9

The process id of port 8080 will be picked and killed forcefully using kill -9.

$(function() { $( "#draggable" ).draggable({ containment: "window" }); });

of this code does not display. Full code and Demo: http://www.limitsizbilgi.com/div-tasima-surukle-birak-div-drag-and-drop-jquery.html

In order to limit the element inside its parent:

$( "#draggable" ).draggable({ containment: "window" });

You can generate pairs like this:

{(x, x + 2) for x in r if x + 2 in r}

Then all that is left to do is to get a condition to make them prime, which you have already done in the first example.

A different way of doing it: (Although slower for large sets of primes)

{(x, y) for x in r for y in r if x + 2 == y}

There's no way to initiate a file transfer back to/from local Windows from a SSH session opened in PuTTY window.

Though PuTTY supports connection-sharing.

While you still need to run a compatible file transfer client (the pscp or psftp), no new login is required, it automatically (if enabled) makes use of an existing PuTTY session.

To enable the sharing see:
Sharing an SSH connection between PuTTY tools.

Alternative way is to use WinSCP, a GUI SFTP/SCP client. While you browse the remote site, you can anytime open SSH terminal to the same site using Open in PuTTY button.

See Opening Session in PuTTY.

With an additional setup, you can even make PuTTY automatically navigate to the same directory you are browsing with WinSCP.

See Opening PuTTY in the Same Directory.

(I'm the author of WinSCP)

Another way, using cut instead of sed.

result=`echo $pid | cut -c 5-`

I agree with the use of instanceof already mentioned.

An additional benefit of using instanceof is that when used with a null reference instanceof of will return false, while a.getClass() would throw a NullPointerException.

There is one way that I have used my self. Go to Control Panel\Programs\Turn Windows features on or off then uninstall IIS and all of its components completely. I restart windows but I'm not sure if it's required or not. Then install it again from the same path.

It looks like people answered the first part of your question (use application/json).

For the second part: It is perfectly legal to send query parameters in a HTTP POST Request.

Example:

POST /members?id=1234 HTTP/1.1
Host: www.example.com
Content-Type: application/json

{"email":"[email protected]"}

Query parameters are commonly used in a POST request to refer to an existing resource. The above example would update the email address of an existing member with the id of 1234.

Beside all the guidance mentioned above,you can also check all the data.

If there are blanks between words, you must replace them with "_".

However that how I solve my own problem.

No. The best you can do is to use a border-bottom with a different color, but that isn't really underlining.

In my OnCreate(Bundle), I generally do the following:

this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Apache Commons

    for (Date dateIter = fromDate; !dateIter.after(toDate); dateIter = DateUtils.addDays(dateIter, 1)) {
        // ...
    }

Each argument passed via command line can be accessed with: Wscript.Arguments.Item(0) Where the zero is the argument number: ie, 0, 1, 2, 3 etc.

So in your code you could have:

strFolder = Wscript.Arguments.Item(0) 

Set FSO = CreateObject("Scripting.FileSystemObject")
Set File = FSO.OpenTextFile(strFolder, 2, True)
File.Write "testing"
File.Close
Set File = Nothing
Set FSO = Nothing
Set workFolder = Nothing

Using wscript.arguments.count, you can error trap in case someone doesn't enter the proper value, etc.

MS Technet examples

This is the most elegant solution I have created. It uses binary search, doing 10 iterations. The naive way was to do a while loop and increase the font size by 1 until the element started to overflow. You can determine when an element begins to overflow using element.offsetHeight and element.scrollHeight. If scrollHeight is bigger than offsetHeight, you have a font size that is too big.

Binary search is a much better algorithm for this. It also is limited by the number of iterations you want to perform. Simply call flexFont and insert the div id and it will adjust the font size between 8px and 96px.

I have spent some time researching this topic and trying different libraries, but ultimately I think this is the easiest and most straightforward solution that will actually work.

Note if you want you can change to use offsetWidth and scrollWidth, or add both to this function.

// Set the font size using overflow property and div height
function flexFont(divId) {
    var content = document.getElementById(divId);
    content.style.fontSize = determineMaxFontSize(content, 8, 96, 10, 0) + "px";
};

// Use binary search to determine font size
function determineMaxFontSize(content, min, max, iterations, lastSizeNotTooBig) {
    if (iterations === 0) {
        return lastSizeNotTooBig;
    }
    var obj = fontSizeTooBig(content, min, lastSizeNotTooBig);

    // if `min` too big {....min.....max.....}
    // search between (avg(min, lastSizeTooSmall)), min)
    // if `min` too small, search between (avg(min,max), max)
    // keep track of iterations, and the last font size that was not too big
    if (obj.tooBig) {
        (lastSizeTooSmall === -1) ?
            determineMaxFontSize(content, min / 2, min, iterations - 1, obj.lastSizeNotTooBig, lastSizeTooSmall) :
                determineMaxFontSize(content, (min + lastSizeTooSmall) / 2, min, iterations - 1, obj.lastSizeNotTooBig, lastSizeTooSmall);

    } else {
        determineMaxFontSize(content, (min + max) / 2, max, iterations - 1, obj.lastSizeNotTooBig, min);
    }
}

// determine if fontSize is too big based on scrollHeight and offsetHeight, 
// keep track of last value that did not overflow
function fontSizeTooBig(content, fontSize, lastSizeNotTooBig) {
    content.style.fontSize = fontSize + "px";
    var tooBig = content.scrollHeight > content.offsetHeight;
    return {
        tooBig: tooBig,
        lastSizeNotTooBig: tooBig ? lastSizeNotTooBig : fontSize
    };
}

I used the below, less code

string fileName = "C:\file.docx";
MessageBox.Show(Path.Combine(Path.GetDirectoryName(fileName),Path.GetFileNameWithoutExtension(fileName)));

Output will be

C:\file

I meant in the template() call..

You just need to pass the results as an object. So instead of calling

var html = template(data);

do

var html = template({apidata: data});

and use {{#each apidata}} in your template code

demo at http://jsfiddle.net/KPCh4/4/
(removed some leftover if code that crashed)

For example, I get date/time in format Spanish.

$('#timePicker').datetimepicker({
    defaultDate: new Date(),
    format:'DD/MM/YYYY HH:mm'
});

d5d "cuts" five lines

I usually just throw the number in the middle like:

d7l = delete 7 letters

If you just wanted to change the example and put the table at the top, then loc='top' in the table declaration is what you need,

the_table = ax.table(cellText=cell_text,
                      rowLabels=rows,
                      rowColours=colors,
                      colLabels=columns,
                      loc='top')

Then adjusting the plot with,

plt.subplots_adjust(left=0.2, top=0.8)

A more flexible option is to put the table in its own axis using subplots,

import numpy as np
import matplotlib.pyplot as plt


fig, axs =plt.subplots(2,1)
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
axs[0].axis('tight')
axs[0].axis('off')
the_table = axs[0].table(cellText=clust_data,colLabels=collabel,loc='center')

axs[1].plot(clust_data[:,0],clust_data[:,1])
plt.show()

which looks like this,

You are then free to adjust the locations of the axis as required.

Some people may find an async example useful:

var response = await fetch("https://httpbin.org/ip");
var body = await response.json(); // .json() is asynchronous and therefore must be awaited

json() converts the response's body from a ReadableStream to a json object.

The await statements must be wrapped in an async function, however you can run await statements directly in the console of Chrome (as of version 62).

Use Ruby way

var public: String = "\(Audience.Public)"

I changed in express 4.0 the basic authentication with http-auth, the code is:

var auth = require('http-auth');

var basic = auth.basic({
        realm: "Web."
    }, function (username, password, callback) { // Custom authentication method.
        callback(username === "userName" && password === "password");
    }
);

app.get('/the_url', auth.connect(basic), routes.theRoute);

Simple check to see if two time periods overlap:

bool overlap = a.start < b.end && b.start < a.end;

or in your code:

bool overlap = tStartA < tEndB && tStartB < tEndA;

(Use <= instead of < if you change your mind about wanting to say that two periods that just touch each other overlap.)

Add a metatag to your header

<meta http-equiv="Content-Type" content="text/html;charset=utf-8" />

This expands the amount of characters you can use.

Easy way, use type="number" if it works for your use case:

<input type="number" ng-model="myText" name="inputName">

Another easy way: ng-pattern can also be used to define a regex that will limit what is allowed in the field. See also the "cookbook" page about forms.

Hackish? way, $watch the ng-model in your controller:

<input type="text"  ng-model="myText" name="inputName">

Controller:

$scope.$watch('myText', function() {
   // put numbersOnly() logic here, e.g.:
   if ($scope.myText  ... regex to look for ... ) {
      // strip out the non-numbers
   }
})

Best way, use a $parser in a directive. I'm not going to repeat the already good answer provided by @pkozlowski.opensource, so here's the link: https://stackoverflow.com/a/14425022/215945

All of the above solutions involve using ng-model, which make finding this unnecessary.

Using ng-change will cause problems. See AngularJS - reset of $scope.value doesn't change value in template (random behavior)

Small but IMPORTANT notices:

1. FB.getLoginStatus must be called after FB.init, otherwise it will not fire the event.

2. you can use FB.Event.subscribe('auth.statusChange', callback), but it will not fire when user is not logged in facebook.

Here is the working example with both functions

window.fbAsyncInit = function() {
    FB.Event.subscribe('auth.statusChange', function(response) {
        console.log( "FB.Event.subscribe auth.statusChange" );
        console.log( response );
    });

    FB.init({
        appId   : "YOUR APP KEY HERE",
        cookie  : true,  // enable cookies to allow the server to access
                // the session
        xfbml   : true,  // parse social plugins on this page
        version : 'v2.1', // use version 2.1
        status  : true
    });

    FB.getLoginStatus(function(response){
        console.log( "FB.getLoginStatus" );
        console.log( response );
    });

};

// Load the SDK asynchronously
(function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_US/sdk.js";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));

You weren't far from the result! This does it:

awk '{NF--; print $NF}' file

This decrements the number of fields in one, so that $NF contains the former penultimate.

Test

Let's generate some numbers and print them on groups of 5:

$ seq 12 | xargs -n5
1 2 3 4 5
6 7 8 9 10
11 12

Let's print the penultimate on each line:

$ seq 12 | xargs -n5 | awk '{NF--; print $NF}'
4
9
11

Starting with Google Play 4.9, the app info display has been changed and the promo graphic is displayed at the top.

The promo graphic will be required soon.

The promo text has turned into a short description and is now shown on the main info page, before the user presses it to view the full description.

The easiest way that I know of to get the number of entries in a table is with '#'. #tableName gets the number of entries as long as they are numbered:

tbl={
    [1]
    [2]
    [3]
    [4]
    [5]
}
print(#tbl)--prints the highest number in the table: 5

Sadly, if they are not numbered, it won't work.

The three possible solutions suggested here have different use cases.

1. Use .equals when comparing ObjectID on two mongoDocuments like this

   results.userId.equals(AnotherMongoDocument._id)

2. Use .toString() when comparing a string representation of ObjectID to an ObjectID of a mongoDocument. like this

   results.userId === AnotherMongoDocument._id.toString()

First of all, there're two kinds of keystores.

Individual and General

The application will use the one indicated in the startup or the default of the system.

It will be a different folder if JRE or JDK is running, or if you check the personal or the "global" one.

They are encrypted too

In short, the path will be like:

$JAVA_HOME/lib/security/cacerts for the "general one", who has all the CA for the Authorities and is quite important.

In Python2, print was a keyword which introduced a statement:

print "Hi"

In Python3, print is a function which may be invoked:

print ("Hi")

In both versions, % is an operator which requires a string on the left-hand side and a value or a tuple of values or a mapping object (like dict) on the right-hand side.

So, your line ought to look like this:

print("a=%d,b=%d" % (f(x,n),g(x,n)))

Also, the recommendation for Python3 and newer is to use {}-style formatting instead of %-style formatting:

print('a={:d}, b={:d}'.format(f(x,n),g(x,n)))

Python 3.6 introduces yet another string-formatting paradigm: f-strings.

print(f'a={f(x,n):d}, b={g(x,n):d}')

The location of the Temporary Internet Files folder depends on your version of Windows and whether or not you are using user profiles.

• If you have Windows Vista, then temporary Internet files are in these locations (note that on your PC they can be on some drive other than C):

  C:\Users[username]\AppData\Local\Microsoft\Windows\Temporary Internet Files\ C:\Users[username]\AppData\Local\Microsoft\Windows\Temporary Internet Files\Low\

  Note that you will have to change the settings of Windows Explorer to show all kinds of files (including the protected system files) in order to access these folders.

• If you have Windows XP or Windows 2000, then temporary Internet files are in this location (note that on your PC they can be on some drive other than C):

  C:\Documents and Settings[username]\Local Settings\Temporary Internet Files\

  If you have only one user account, then replace [username] with Administrator to get the path of the Temporary Internet Files folder.

• If you have Windows Me, Windows 98, Windows NT or Windows 95, then index.dat files are in these locations:

  C:\Windows\Temporary Internet Files\
  C:\Windows\Profiles[username]\Temporary Internet Files\

  Note that on your computer, the Windows directory may not be C:\Windows but some other directory. If you don't have a Profiles directory in your Windows directory, don't worry — this just means that you are not using user profiles.

I just executed connection.close() by adding it as first statement and it was solved. Then i removed the line.

You can also click on the Formulas tab in Excel and select Show Formulas, then use the regular "Find" and "Replace" function. This should not affect the rest of your formula.

On Postgres 10:

SELECT to_timestamp(CAST(epoch_ms as bigint)/1000)

I resolved the same problem by this:

git config http.postBuffer 524288000

It might be because of the large size of repository and default buffer size of git so by doing above(on git bash), git buffer size will get increase.

Cheers!

Activity:

public class MyActivity extends ActionBarActivity implements ShowDialog
{
    ..

    @Override
    public void showDialog(DialogFragment dialogFragment)
    {
        FragmentManager fragmentManager = getSupportFragmentManager();
        dialogFragment.show(fragmentManager, "dialog");
    }
}

DialogFragment layout:

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

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

</RelativeLayout>

As the name dialogfragment_heightfixhiddenbtn shows, I just couldn't figure out a way to fix that the bottom button's height was cut in half despite saying wrap_content, so I added a hidden button to be "cut" in half instead. Sorry for the hack.

The short version

startActivity(new Intent(Intent.ACTION_VIEW, 
    Uri.parse("http://almondmendoza.com/android-applications/")));

should work as well...

Another Approach:

When Laravel tries to connect to database, if the connection fails or if it finds any errors it will return a PDOException error. We can catch this error and redirect the action

Add the following code in the app/filtes.php file.

App::error(function(PDOException $exception)
{
    Log::error("Error connecting to database: ".$exception->getMessage());

    return "Error connecting to database";
});

Hope this is helpful.

I am assuming your startHour column and @startHour variable are both DATETIME; In that case, you should be converting to a string:

SELECT timeEvent
FROM tbEvents
WHERE convert(VARCHAR(8), startHour, 8) >= convert(VARCHAR(8), @startHour, 8)

The second example would be the one to go with, not just for readability, but because of the fact that in the first example, If NOT value1 would return a boolean value to be compared against value2. IOW, you need to rewrite that example as

If NOT (value1 = value2)

which just makes the use of the NOT keyword pointless.

The 1./2 syntax works because 1. is a float. It's the same as 1.0. The dot isn't a special operator that makes something a float. So, you need to either turn one (or both) of the operands into floats some other way -- for example by using float() on them, or by changing however they were calculated to use floats -- or turn on "true division", by using from __future__ import division at the top of the module.

ng-bind-html-unsafe only renders the content as HTML. It doesn't bind Angular scope to the resulted DOM. You have to use $compile service for that purpose. I created this plunker to demonstrate how to use $compile to create a directive rendering dynamic HTML entered by users and binding to the controller's scope. The source is posted below.

demo.html

<!DOCTYPE html>
<html ng-app="app">

  <head>
    <script data-require="[email protected]" data-semver="1.0.7" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js"></script>
    <script src="script.js"></script>
  </head>

  <body>
    <h1>Compile dynamic HTML</h1>
    <div ng-controller="MyController">
      <textarea ng-model="html"></textarea>
      <div dynamic="html"></div>
    </div>
  </body>

</html>

script.js

var app = angular.module('app', []);

app.directive('dynamic', function ($compile) {
  return {
    restrict: 'A',
    replace: true,
    link: function (scope, ele, attrs) {
      scope.$watch(attrs.dynamic, function(html) {
        ele.html(html);
        $compile(ele.contents())(scope);
      });
    }
  };
});

function MyController($scope) {
  $scope.click = function(arg) {
    alert('Clicked ' + arg);
  }
  $scope.html = '<a ng-click="click(1)" href="#">Click me</a>';
}

No, there is no built-in MySQL command for that. There are various tools and scripts that support it, you can kill some connections manually or restart the server (but that will be slower).

Use SHOW PROCESSLIST to view all connections, and KILL the process ID's you want to kill.

You could edit the timeout setting to have the MySQL daemon kill the inactive processes itself, or raise the connection count. You can even limit the amount of connections per username, so that if the process keeps misbehaving, the only affected process is the process itself and no other clients on your database get locked out.

If you can't connect yourself anymore to the server, you should know that MySQL always reserves 1 extra connection for a user with the SUPER privilege. Unless your offending process is for some reason using a username with that privilege...

Then after you can access your database again, you should fix the process (website) that's spawning that many connections.

It's totally feasible now. Google now allow you to transfer Android apps between accounts. Please take a look at this link: https://support.google.com/googleplay/android-developer/checklist/3294213?hl=en

I had come across the same requirement to flatter multidimensional array into single dimensional array than search value using text in key. here is my code

$data = '{
    "json_data": [{
            "downtime": true,

            },
            "ints": {
                "int": [{
                    "rle": "pri",
                    "device": "laptop",

$data = json_decode($data,true);


$stack = &$data;
$separator = '.';
$toc = array();

while ($stack) {
    list($key, $value) = each($stack);
    unset($stack[$key]);
    if (is_array($value)) {
        $build = array($key => ''); # numbering without a title.
        foreach ($value as $subKey => $node)
            $build[$key . $separator . $subKey] = $node;
        $stack = $build + $stack;

echo '<pre/>';
