You could try

cat FILE | awk '{print NF}'

The above steps, though helpful, didnt work for me on Windows 8. I don't know the co-relation, but the below steps worked. Basically a change in the cacert.pem file. Hope this helps someone.

• Download cacert.pem file from here: http://curl.haxx.se/docs/caextract.html
• Save the file in your PHP installation folder. (eg: If using xampp – save it in c:\Installation_Dir\xampp\php\cacert.pem).
• Open your php.ini file and add these lines:
• curl.cainfo=”C:\Installation_Dir\xampp\php\cacert.pem” openssl.cafile=”C:\Installation_Dir\xampp\php\cacert.pem”
• Restart your Apache server and that should fix it (Simply stop and start the services as needed).

You can use git stash - if something goes wrong, you can still revert from the stash. Similar to some other answer here, but this one also removes all unstaged files and also all unstaged deletes:

git add .
git stash

if you check that everything is OK, throw the stash away:

git stash drop

The answer from Bilal Maqsood with git clean also worked for me, but with the stash I have more control - if I do sth accidentally, I can still get my changes back

UPDATE

I think there is 1 more change (don't know why this worked for me before):

git add . -A instead of git add .

without the -A the removed files will not be staged

Here's a way to drop foreign key constraint, it will work. ALTER TABLE location.location_id DROP FOREIGN KEY location_ibfk_1;

Well theres a lot of different ways but if you only want to DISPLAY the text and not STORE it anywhere then you just use: findstr /v "randomtextthatnoonewilluse" filename.txt

if you need to change your column output date format just use to_char this well get you a string, not a date.

An extension to what GenericTypeTea says - Here is a concrete example:

<form onsubmit="return false">

The above form will not submit, whereas...

<form onsubmit="false">

...does nothing, i.e. the form will submit.

Without the return, onsubmit doesn't receive a value and the event is executed just like without any handler at all.

See example below for using a POJO as pseudo entity to retrieve result from native query without using complex SqlResultSetMapping. Just need two annotations, a bare @Enity and a dummy @Id in your POJO. @Id can be used on any field of your choice, an @Id field can have duplicate keys but not null values.

Since @Enity does not map to any physical table, so this POJO is called a pseudo entity.

Environment: eclipselink 2.5.0-RC1, jpa-2.1.0, mysql-connector-java-5.1.14

Best current version, without need to deal with numeric search within NSString is to define macros (See original answer: Check iPhone iOS Version)

Those macros do exist in github, see: https://github.com/carlj/CJAMacros/blob/master/CJAMacros/CJAMacros.h

Like this:

#define SYSTEM_VERSION_EQUAL_TO(v)                  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
#define SYSTEM_VERSION_GREATER_THAN(v)              ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v)                 ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v)     ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)

and use them like this:

if (SYSTEM_VERSION_LESS_THAN(@"5.0")) {
    // code here
}

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"6.0")) {
    // code here
}

Outdated version below

to get OS version:

[[UIDevice currentDevice] systemVersion]

returns string, which can be turned into int/float via

-[NSString floatValue]
-[NSString intValue]

like this

Both values (floatValue, intValue) will be stripped due to its type, 5.0.1 will become 5.0 or 5 (float or int), for comparing precisely, you will have to separate it to array of INTs check accepted answer here: Check iPhone iOS Version

NSString *ver = [[UIDevice currentDevice] systemVersion];
int ver_int = [ver intValue];
float ver_float = [ver floatValue];

and compare like this

NSLog(@"System Version is %@",[[UIDevice currentDevice] systemVersion]);
NSString *ver = [[UIDevice currentDevice] systemVersion];
float ver_float = [ver floatValue];
if (ver_float < 5.0) return false;

For Swift 4.0 syntax

below example is just checking if the device is of iOS11 or greater version.

let systemVersion = UIDevice.current.systemVersion
if systemVersion.cgFloatValue >= 11.0 {
    //"for ios 11"
  }
else{
   //"ios below 11")
  }

Server-side functions are on the server-side, client-side functions reside on the client. What you can do is you have to set hidden form variable and submit the form, then on page use Page_Load handler you can access value of variable and call the server method.

Only the "Continue For" is an acceptable standard (the rest leads to "spaghetti code").

At least with "continue for" the programmer knows the code goes directly to the top of the loop.

For purists though, something like this is best since it is pure "non-spaghetti" code.

Dim bKeepGoing as Boolean 
For Each I As Item In Items
  bKeepGoing = True
  If I = x Then
    bKeepGoing = False
  End If
  if bKeepGoing then
    ' Do something
  endif
Next

For ease of coding though, "Continue For" is OK. (Good idea to comment it though).

Using "Continue For"

For Each I As Item In Items
  If I = x Then
    Continue For   'skip back directly to top of loop
  End If
  ' Do something
Next

You have 2 options: Redirect the output of the script to a file, Introduce a log file in the script and

1. Redirecting output to a file:

Here you assume that the script outputs all necessary info, including warning and error messages. You can then redirect the output to a file of your choice.

./runTests &> output.log

The above command redirects both the standard output and the error output to your log file.

Using this approach you don't have to introduce a log file in the script, and so the logic is a tiny bit easier.

2. Introduce a log file to the script:

In your script add a log file either by hard coding it:

logFile='./path/to/log/file.log'

or passing it by a parameter:

logFile="${1}"  # This assumes the first parameter to the script is the log file

It's a good idea to add the timestamp at the time of execution to the log file at the top of the script:

date '+%Y%-m%d-%H%M%S' >> "${logFile}"

You can then redirect your error messages to the log file

if [ condition ]; then
    echo "Test cases failed!!" >> "${logFile}"; 
fi

This will append the error to the log file and continue execution. If you want to stop execution when critical errors occur, you can exit the script:

if [ condition ]; then
    echo "Test cases failed!!" >> "${logFile}"; 
    # Clean up if needed
    exit 1;
fi

Note that exit 1 indicates that the program stop execution due to an unspecified error. You can customize this if you like.

Using this approach you can customize your logs and have a different log file for each component of your script.

If you have a relatively small script or want to execute somebody else's script without modifying it to the first approach is more suitable.

If you always want the log file to be at the same location, this is the better option of the 2. Also if you have created a big script with multiple components then you may want to log each part differently and the second approach is your only option.

If you are working with redis and Java 8, you can take a look at JetCache:

@Cached(expire = 10, timeUnit = TimeUnit.MINUTES) User getUserById(long userId);

try this

var date = new Date();    
$.ajax(
   {
       type: "POST",
       url: "/Group/Refresh",
       contentType: "application/json; charset=utf-8",
       data: "{ 'MyDate': " + date.getTimezoneOffset() + " }",
       success: function (result) {
           //do something
       },
       error: function (req, status, error) {
           //error                        
       }
   });

In C#

DateTime.Now.ToUniversalTime().AddMinutes(double.Parse(MyDate)).ToString();

Here are the docs about the "new" format syntax. An example would be:

"({:d} goals, ${:d})".format(self.goals, self.penalties)

If both goals and penalties are integers (i.e. their default format is ok), it could be shortened to:

"({} goals, ${})".format(self.goals, self.penalties)

And since the parameters are fields of self, there's also a way of doing it using a single argument twice (as @Burhan Khalid noted in the comments):

"({0.goals} goals, ${0.penalties})".format(self)

Explaining:

• {} means just the next positional argument, with default format;
• {0} means the argument with index 0, with default format;
• {:d} is the next positional argument, with decimal integer format;
• {0:d} is the argument with index 0, with decimal integer format.

There are many others things you can do when selecting an argument (using named arguments instead of positional ones, accessing fields, etc) and many format options as well (padding the number, using thousands separators, showing sign or not, etc). Some other examples:

"({goals} goals, ${penalties})".format(goals=2, penalties=4)
"({goals} goals, ${penalties})".format(**self.__dict__)

"first goal: {0.goal_list[0]}".format(self)
"second goal: {.goal_list[1]}".format(self)

"conversion rate: {:.2f}".format(self.goals / self.shots) # '0.20'
"conversion rate: {:.2%}".format(self.goals / self.shots) # '20.45%'
"conversion rate: {:.0%}".format(self.goals / self.shots) # '20%'

"self: {!s}".format(self) # 'Player: Bob'
"self: {!r}".format(self) # '<__main__.Player instance at 0x00BF7260>'

"games: {:>3}".format(player1.games)  # 'games: 123'
"games: {:>3}".format(player2.games)  # 'games:   4'
"games: {:0>3}".format(player2.games) # 'games: 004'

Note: As others pointed out, the new format does not supersede the former, both are available both in Python 3 and the newer versions of Python 2 as well. Some may say it's a matter of preference, but IMHO the newer is much more expressive than the older, and should be used whenever writing new code (unless it's targeting older environments, of course).

I tried the following and it works for me better

Code:

.unstyled-link{ 
  color: inherit;
  text-decoration: inherit;
  &:link,
  &:hover {
    color: inherit;
    text-decoration: inherit;
  }
}

to deal with Null Comparisons use Object.Equals() instead of ==

check this reference

try this

DECLARE @StartTime DATETIME
SET @StartTime = GETDATE()

  SET @EndTime = GETDATE()
  PRINT 'StartTime = ' + CONVERT(VARCHAR(30),@StartTime,121)
  PRINT '  EndTime = ' + CONVERT(VARCHAR(30),@EndTime,121)
  PRINT ' Duration = ' + CONVERT(VARCHAR(30),@EndTime -@starttime,114)

If that doesn't do it, then try SET STATISTICS TIME ON

@BrenBarn's answer says it all, but if you're like me it might take a while to understand. Here's my case and how @BrenBarn's answer applies to it, perhaps it will help you.

The case

package/
    __init__.py
    subpackage1/
        __init__.py
        moduleX.py
    moduleA.py

Using our familiar example, and add to it that moduleX.py has a relative import to ..moduleA. Given that I tried writing a test script in the subpackage1 directory that imported moduleX, but then got the dreaded error described by the OP.

Solution

Move test script to the same level as package and import package.subpackage1.moduleX

Explanation

As explained, relative imports are made relative to the current name. When my test script imports moduleX from the same directory, then module name inside moduleX is moduleX. When it encounters a relative import the interpreter can't back up the package hierarchy because it's already at the top

When I import moduleX from above, then name inside moduleX is package.subpackage1.moduleX and the relative import can be found

My best guess at why you had problems with the ----- covering your first result is that you actually read the input line from a file. That line probably had a \r on the end so you ended up with something like this:

-----------test2-------test3

What happened is the machine actually printed this:

test-------test2-------test3\r-------

That means, because of the carriage return at the end of test3, that the dashes after test3 were printed over the top of the first word (and a few of the existing dashes between test and test2 but you wouldn't notice that because they were already dashes).

you can join both tables even on UPDATE statements,

UPDATE  a
SET     a.marks = b.marks
FROM    tempDataView a
        INNER JOIN tempData b
            ON a.Name = b.Name

• SQLFiddle Demo

for faster performance, define an INDEX on column marks on both tables.

using SUBQUERY

UPDATE  tempDataView 
SET     marks = 
        (
          SELECT marks 
          FROM tempData b 
          WHERE tempDataView.Name = b.Name
        )

Here is a vanilla solution. Can be used in jQuery if the event passed to the function is event.originalEvent which jQuery makes available as property of the jQuery event. Or if inside the callback function under we add before first line: event = event.originalEvent;.

This code normalizes the wheel speed/amount and is positive for what would be a forward scroll in a typical mouse, and negative in a backward mouse wheel movement.

Demo: http://jsfiddle.net/BXhzD/

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

function report(ammout) {
    wheel.innerHTML = 'wheel ammout: ' + ammout;
}

function callback(event) {
    var normalized;
    if (event.wheelDelta) {
        normalized = (event.wheelDelta % 120 - 0) == -0 ? event.wheelDelta / 120 : event.wheelDelta / 12;
    } else {
        var rawAmmount = event.deltaY ? event.deltaY : event.detail;
        normalized = -(rawAmmount % 3 ? rawAmmount * 10 : rawAmmount / 3);
    }
    report(normalized);
}

var event = 'onwheel' in document ? 'wheel' : 'onmousewheel' in document ? 'mousewheel' : 'DOMMouseScroll';
window.addEventListener(event, callback);

There is also a plugin for jQuery, which is more verbose in the code and some extra sugar: https://github.com/brandonaaron/jquery-mousewheel

put public, protected or private before the $connection.

input.next();
String s = input.toString();

change it to

String s = input.next();

May be that's what you were trying to do.

Try this

box-sizing: border-box;

I would use Environment.Newline when I wanted to insert a newline for a string, but not to remove all newlines from a string.

Depending on your platform you can have different types of newlines, but even inside the same platform often different types of newlines are used. In particular when dealing with file formats and protocols.

string ReplaceNewlines(string blockOfText, string replaceWith)
{
    return blockOfText.Replace("\r\n", replaceWith).Replace("\n", replaceWith).Replace("\r", replaceWith);
}

What worked for me (and probably not yet answered here till now) ::

While working on a Selenium project and ANT, I had copied and placed TWO different "BUILD.xml" files from 2 different sources in the Project's ROOT directory. This resulted in this RED-EXCLAMATION-MARK, which disappeared as soon as I moved one of the BUILD.xml file to another folder.

As to "why I had two BUILD.xml files in ONE project?", I was actually playing around with ANT's config from various BUILD.xml files.

Another nice package which I used for migrating form a beta version of Angular2 to Angular2 2.0.0 final is npm-check-updates

It shows the latest available version of all packages specified within your package.json. In contrast to npm outdated it is also capable to edit your package.json, enabling you to do a npm upgrade later.

Install

sudo npm install -g npm-check-updates

Usage

I found this sample script here that seems to be working pretty well:

SELECT r.session_id,r.command,CONVERT(NUMERIC(6,2),r.percent_complete)
AS [Percent Complete],CONVERT(VARCHAR(20),DATEADD(ms,r.estimated_completion_time,GetDate()),20) AS [ETA Completion Time],
CONVERT(NUMERIC(10,2),r.total_elapsed_time/1000.0/60.0) AS [Elapsed Min],
CONVERT(NUMERIC(10,2),r.estimated_completion_time/1000.0/60.0) AS [ETA Min],
CONVERT(NUMERIC(10,2),r.estimated_completion_time/1000.0/60.0/60.0) AS [ETA Hours],
CONVERT(VARCHAR(1000),(SELECT SUBSTRING(text,r.statement_start_offset/2,
CASE WHEN r.statement_end_offset = -1 THEN 1000 ELSE (r.statement_end_offset-r.statement_start_offset)/2 END)
FROM sys.dm_exec_sql_text(sql_handle))) AS [SQL]
FROM sys.dm_exec_requests r WHERE command IN ('RESTORE DATABASE','BACKUP DATABASE')

When I know the string is going to be reasonably short then I use the following one liner... (remember to escape backslashes)

// if str is C:\windows\file system\path\picture name.jpg
alert( str.split('\\').pop() );

alert pops up with picture name.jpg

You can split on an empty string:

var chars = "overpopulation".split('');

If you just want to access a string in an array-like fashion, you can do that without split:

var s = "overpopulation";
for (var i = 0; i < s.length; i++) {
    console.log(s.charAt(i));
}

You can also access each character with its index using normal array syntax. Note, however, that strings are immutable, which means you can't set the value of a character using this method, and that it isn't supported by IE7 (if that still matters to you).

var s = "overpopulation";

console.log(s[3]); // logs 'r'

There is types.SimpleNamespace class in Python 3.3+:

obj = someobject
obj.a = SimpleNamespace()
for p in params:
    setattr(obj.a, p, value)
# obj.a.attr1

collections.namedtuple, typing.NamedTuple could be used for immutable objects. PEP 557 -- Data Classes suggests a mutable alternative.

For a richer functionality, you could try attrs package. See an example usage.

Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:

openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp

This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).

I am aware that this is a old post but I hope that this will still help somebody, with what I hope is a simple example:

background:

I had a many to many case: the same user is listed multiple times with multiple values and I wanted to Create a new record, hence UPDATE wouldn't make sense in my case and I needed to address a particular user just like I would do using a WHERE clause.

INSERT into MyTable(aUser,aCar)
value(User123,Mini)

By using this construct you actually target a specific user (user123,who has other records) so you don't really need a where clause, I reckon.

the output could be:

aUser   aCar
user123 mini
user123 HisOtherCarThatWasThereBefore

Using a (very) commonly used package is prefered:

A comprehansive comparison between diffreent formats made by me in this post- https://maxondev.com/serialization-performance-comparison-c-net-formats-frameworks-xmldatacontractserializer-xmlserializer-binaryformatter-json-newtonsoft-servicestack-text/

Just one sample from the post-

Here is my take on the problem. Works for Python3. The main features are:

• Each Python version is compiled from source
• All versions are installed locally
• Does not mangle your system's default Python installation in any way
• Each Python version is isolated with virtualenv

Prerequisites: If you are using some bare-bones thin client with no extra turf installed, you should run this first (in ubuntu 18.04 at least, extra packages added for convenience):

sudo apt-get update
sudo apt-get install software-properties-common
sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install -y build-essential cmake

sudo apt-get install -y zlib1g zlib1g-dev libsqlite3-dev \
openssl libssl-dev libffi-dev unzip pciutils net-tools \
libblas-dev gfortran libblas3 

The steps are as follows:

0. If you have several extra python versions installed in some other way, get rid of them, e.g., remove $HOME/.local/lib/python3.x, etc. (also the globally installed ones). Don't touch your system's default python3 version though.

1. Download source for different python versions under the following directory structure:

    $HOME/
        python_versions/ : download Python-*.tgz packages here and "tar xvf" them.  You'll get directories like this:
          Python-3.4.8/
          Python-3.6.5/
          Python-3.x.y/
          ...
   

2. At each "Python-3.x.y/" directory, do the following (do NOT use "sudo" in any of the steps!):

    mkdir root
    ./configure --prefix=$PWD/root 
    make -j 2
    make install
    virtualenv --no-site-packages -p root/bin/python3.x env
   

3. At "python_versions/" create files like this:

    env_python3x.bash:
   
    #!/bin/bash
    echo "type deactivate to exit"
    source $HOME/python_versions/Python-3.x.y/env/bin/activate
   

4. Now, anytime you wish to opt for python3.x, do

    source $HOME/python_versions/env_python3x.bash
   

to enter the virtualenv

6. While in the virtualenv, install your favorite python packages with

    pip install --upgrade package_name
   

7. To exit the virtualenv and python version just type "deactivate"

UPDATE

It seems that --no-site-packages is deprecated. There's an easy fix for this: Once you have activated the virtualenv, just point the HOME env variable to somewhere else than your actual home directory, i.e.:

export HOME=some/where/else

A nice way to do this in general is:

• Create virtualenv
• Activate virtualenv
• If you want to "recycle" existing libraries to your virtualenv, softlink them from your existing install, i.e. ln -s $HOME/.local/lib/python3.6/site-packages/numpy $PWD/venv/lib/python3.6/site-packages/
• Do export PYTHONPATH=, export HOME=/some/other/dir

Now you should have custom-isolated virtualenv.

UPDATE 2 / SUDO

Wan't to force sudo to use your virtualenv?

Defaults        secure_path="/home/USENAME/Python-3.x.y/env/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
Defaults        env_keep += "VIRTUAL_ENV"
Defaults        env_keep += "PYTHONPATH"

Now try "sudo python3 --version" and magic should happen

UPDATE 3 / DOCKER

Enable virtualenv inside your docker (of course, you have built it in your docker image):

ENV VIRTUAL_ENV=/home/USER/Python-3.x.y/env
ENV PYTHONPATH=
ENV PATH="$VIRTUAL_ENV/bin:$PATH"

var res = exitDictionary
            .Select(p => p.Value).Cast<Dictionary<string, object>>()
            .SelectMany(d => d)
            .Where(p => p.Key == "fieldname1")
            .Select(p => p.Value).Cast<List<Dictionary<string,string>>>()
            .SelectMany(l => l)
            .SelectMany(d=> d)
            .Where(p => p.Key == "valueTitle")
            .Select(p => p.Value)
            .ToList();

This also works, and easy to understand.

You can use regex here:

>>> import re
>>> strs = "foo\tbar\t\tspam"
>>> re.split(r'\t+', strs)
['foo', 'bar', 'spam']

update:

You can use str.rstrip to get rid of trailing '\t' and then apply regex.

>>> yas = "yas\t\tbs\tcda\t\t"
>>> re.split(r'\t+', yas.rstrip('\t'))
['yas', 'bs', 'cda']

Here's a small script implementing this feature (inspired by the Shea Frederick blog article that Kyle mentions):

• Pointer Events Polyfill.

Using plain javascript:

element.parentNode

In jQuery:

element.parent()

If you're just gonna click the button when Enter was pressed how about this?

private void textbox1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Enter)
        {
            buttonSearch.PerformClick();
        }

None of the above worked for me without throwing errors in the console when the box wasn't checked so I did something along these lines instead (onclick and the checkbox function are only being used for demo purposes, in my use case it's part of a much bigger form submission function):

function checkbox() {_x000D_
  var checked = false;_x000D_
  if (document.querySelector('#opt1:checked')) {_x000D_
     checked = true;_x000D_
  }_x000D_
  document.getElementById('msg').innerText = checked;_x000D_
}

<input type="checkbox" onclick="checkbox()" id="opt1"> <span id="msg">Click The Box</span>

you put resource-ref in the description tag in web.xml

another way is to use the range method

foo = [1,2,3,4,5,6]
bar = [10,20,30,40,50,60]
a = foo[0...3]
b = bar[3...6]

print a + b 
=> [1, 2, 3, 40, 50 , 60]

This will definately work for you.

Here is a simple way to send an HTML email, just by specifying the Content-Type header as 'text/html':

import email.message
import smtplib

msg = email.message.Message()
msg['Subject'] = 'foo'
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'
msg.add_header('Content-Type','text/html')
msg.set_payload('Body of <b>message</b>')

# Send the message via local SMTP server.
s = smtplib.SMTP('localhost')
s.starttls()
s.login(email_login,
        email_passwd)
s.sendmail(msg['From'], [msg['To']], msg.as_string())
s.quit()

I ran into this while working on a .NET console app to read the PATH environment variable, and found that using System.Environment.GetEnvironmentVariable will expand the environment variables automatically.

I didn't want that to happen...that means folders in the path such as '%SystemRoot%\system32' were being re-written as 'C:\Windows\system32'. To get the un-expanded path, I had to use this:

string keyName = @"SYSTEM\CurrentControlSet\Control\Session Manager\Environment\";
string existingPathFolderVariable = (string)Registry.LocalMachine.OpenSubKey(keyName).GetValue("PATH", "", RegistryValueOptions.DoNotExpandEnvironmentNames);

Worked like a charm for me.

You'd obviously figure it out after a while but just posting this so that it might help someone. This could also happen when your file path contains any whitespace appended or prepended to it.

Why don't you try to write a function based on Integer.parseInt(String obj) ? The function could accept as parameter your String object, and then tokenize the String and use Integer.parseInt(String obj) to extract the number from the "lucky" substring...

Javadoc of Integer.parseInt(String obj)

If you using v1.3.3 then use following property

autoPlay : 5000

Or using latest version then use following property

autoPlay : true

var a = 10;

myFunction(a);

function myFunction(a){
   window['a'] = 20; // or window.a
}

alert("Value of 'a' outside the function " + a); //outputs 20

With window['variableName'] or window.variableName you can modify the value of a global variable inside a function.

you must enable X11 forwarding in you PuTTy

to do so open PuTTy, go to Connection => SSH => Tunnels and check mark the Enable X11 forwarding

Also sudo to server and export the below variable here IP is your local machine's IP

export DISPLAY=10.75.75.75:0.0

"NUL" is not 0, but refers to the ASCII NUL character. At least, that's how I've seen it used. The null pointer is often defined as 0, but this depends on the environment you are running in, and the specification of whatever operating system or language you are using.

In ANSI C, the null pointer is specified as the integer value 0. So any world where that's not true is not ANSI C compliant.

A couple of examples:

infix fun Double.f(fmt: String) = "%$fmt".format(this)
infix fun Double.f(fmt: Float) = "%${if (fmt < 1) fmt + 1 else fmt}f".format(this)

val pi = 3.14159265358979323

println("""pi = ${pi f ".2f"}""")
println("pi = ${pi f .2f}")

The error indicates that the preflight is getting a redirect response. This can happen for a number of reasons. Find out where you are getting redirected to for clues to why it is happening. Check the network tab in Developer Tools.

One reason, as @Peter T mentioned, is that the API likely requires HTTPS connections rather than HTTP and all requests over HTTP get redirected. The Location header returned by the 302 response would say the same url with http changed to https in this case.

Another reason might be that your authentication token is not getting sent, or is not correct. Most servers are set up to redirect all requests that don't include an authentication token to the login page. Again, check your Location header to see if this is where you're getting sent and also take a look to make sure the browser sent your auth token with the request.

Oftentimes, a server will be configured to always redirect requests that don't have auth tokens to the login page - including your preflight/OPTIONS requests. This is a problem. Change the server configuration to permit OPTIONS requests from non-authenticated users.

The font sizes in your question are an example of what ratio each header should be in comparison to each other, rather than what size they should be themselves (in pixels).

So in response to your question "Is there a 'best practice' for these for mobile phones? - say iphone screen size?", yes there probably is - but you might find what someone says is "best practice" does not work for your layout.

However, to help get you on the right track, this article about building responsive layouts provides a good example of how to calculate the base font-size in pixels in relation to device screen sizes.

The suggested font-sizes for screen resolutions suggested from that article are as follows:

@media (min-width: 858px) {
    html {
        font-size: 12px;
    }
}

@media (min-width: 780px) {
    html {
        font-size: 11px;
    }
}

@media (min-width: 702px) {
    html {
        font-size: 10px;
    }
}

@media (min-width: 724px) {
    html {
        font-size: 9px;
    }
}

@media (max-width: 623px) {
    html {
        font-size: 8px;
    }
}

If you mean VB 6, that would be Private Sub Class_Initialize().

http://msdn.microsoft.com/en-us/library/55yzhfb2(VS.80).aspx

If you mean VB.NET it is Public Sub New() or Shared Sub New().

You can do it using a unicode character also

System.out.print('\u0022' + "Hello" + '\u0022');

I think it shouldn't be just questions, I know a few guys who are brilliant when you interview them but once they get to the real thing they are too much perfectionist I would say that they fail to code the task miserably.

I've been once interviewed and I kinda liked the approach where first employer gave me a technical questionnaire to fill in 30 minutes. If one is successful then he'll be called for a 1 hour interview covering Personality Judgement and Character finding questions plus technical jargons.

Then I've been asked to develop a three page web application in 6 hours time. The constraints impose in application was smartly covering major aspect of application development like a small ERD, Layerd Design, UI Consistency, controls specific problems like using Radio buttons in GridView and Fetching and displaying image types from DB on a web page, one algorithm development, security, Encryption, Hashing, Data representation and manipulation.

Then Next day they followed by a 30 minutes discussion on the developed application covering performance bottleneck areas and improvements on design and used algorithms. And 1 hour optional test to improve your algorithm developed in previous step with a specific condition.

So it took a fair amount of time but this way you can make sure that the person you are hiring knows at-least those concepts which are essential for a good developer to be.

The modal dialog can be positioned on top by overriding its z-index property:

.modal.fade {
  z-index: 10000000 !important;
}

window.location will affect to your browser target. document.location will only affect to your browser and frame/iframe.

I am using as what John Rasch said:

Stream streamContent = taxformUpload.FileContent;

Note: you should use the accepted answer if possible. It's better than mine.

It's quite easy with the GD library.

It's built in usually, you probably have it (use phpinfo() to check)

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");

imagejpeg($image, "folder/file.jpg");

The above answer is better (faster) for most situations, but with GD you can also modify it in some form (cropping for example).

$image = imagecreatefromjpeg("http://images.websnapr.com/?size=size&key=Y64Q44QLt12u&url=http://google.com");
imagecopy($image, $image, 0, 140, 0, 0, imagesx($image), imagesy($image));
imagejpeg($image, "folder/file.jpg");

This only works if allow_url_fopen is true (it is by default)

Yes it is simple to do.

Sub CompactRepair()
  Dim control As Office.CommandBarControl
  Set control = CommandBars.FindControl( Id:=2071 )
  control.accDoDefaultAction
End Sub

Basically it just finds the "Compact and repair" menuitem and clicks it, programatically.

org.apache.http.client.utils.URLEncodedUtils

is a well known library that can do it for you

import org.apache.hc.client5.http.utils.URLEncodedUtils

String url = "http://www.example.com/something.html?one=1&two=2&three=3&three=3a";

List<NameValuePair> params = URLEncodedUtils.parse(new URI(url), Charset.forName("UTF-8"));

for (NameValuePair param : params) {
  System.out.println(param.getName() + " : " + param.getValue());
}

Outputs

one : 1
two : 2
three : 3
three : 3a

The problem was that I needed to have both minGW and MSYS installed and added to PATH.

The problem is now fixed.

1. Click on Window > Show view > Server or right click on the server in "Servers" view, select "Properties".
2. In the "General" panel, click on the "Switch Location" button.
3. The "Location: [workspace metadata]" should replace by something else.
4. Open the Overview screen for the server by double clicking it.
5. In the Server locations tab , select "Use Tomcat location".
6. Save the configurations and restart the Server.

You may want to follow the steps above before starting the server. Because server location section goes grayed-unreachable.

If you want to use 'lengthMenu' together with buttons(copy, export), you have to use this option dom: 'lBfrtip'. Here https://datatables.net/reference/option/dom you can find meaning of each symbol. For example, if you will use like this 'Bfrtip', lengthMenu will not appears.

After reading the excellent up-voted answers, I found that the following point needed emphasis for me, a newcomer to network programming:

TCP-IP connections are bi-directional pathways connecting one address:port combination with another address:port combination. Therefore, whenever you open a connection from your local machine to a port on a remote server (say www.google.com:80), you are also associating a new port number on your machine with the connection, to allow the server to send things back to you, (e.g. 127.0.0.1:65234). It can be helpful to use netstat to look at your machine's connections:

> netstat -nWp tcp (on OS X)
Active Internet connections
Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)    
tcp4       0      0  192.168.0.6.49871      17.172.232.57.5223     ESTABLISHED
...

A unique approach I haven't seen anyone mention!

The only way I was able to get all the customisation I wanted was to use an after_validation callback to allow me to manipulate the error message.

1. Allow the validation message to be created as normal, you don't need to try and change it in the validation helper.

2. create an after_validation callback that will replace that validation message in the back-end before it gets to the view.

3. In the after_validation method you can do anything you want with the validation message, just like a normal string! You can even use dynamic values and insert them into the validation message.

#this could be any validation
validates_presence_of :song_rep_xyz, :message => "whatever you want - who cares - we will replace you later"

after_validation :replace_validation_message

def replace_validation_message
    custom_value = #any value you would like
    errors.messages[:name_of_the_attribute] = ["^This is the replacement message where 
    you can now add your own dynamic values!!! #{custom_value}"]
end

The after_validation method will have far greater scope than the built in rails validation helper, so you will be able to access the object you are validating like you are trying to do with object.file_name. Which does not work in the validation helper where you are trying to call it.

Note: we use the ^ to get rid of the attribute name at the beginning of the validation as @Rystraum pointed out referencing this gem

It looks like details is an array of hashes. So item inside of your block will be the whole hash. Therefore, to check the :qty key, you'd do something like the following:

details.select{ |item| item[:qty] != "" }

That will give you all items where the :qty key isn't an empty string.

official select documentation

You can try out this one as well as. Because this worked for me and it's simple.

<style>
    <%@ include file="/css/style.css" %>
</style>

Based on all the info on the post, I created a little script to make the whole process easy.

@ECHO OFF
netstat -aon |find /i "listening"

SET killport=
SET /P killport=Enter port: 
IF "%killport%"=="" GOTO Kill

netstat -aon |find /i "listening" | find "%killport%"

:Kill
SET killpid=
SET /P killpid=Enter PID to kill: 
IF "%killpid%"=="" GOTO Error

ECHO Killing %killpid%!
taskkill /F /PID %killpid%

GOTO End
:Error
ECHO Nothing to kill! Bye bye!!
:End

pause

A small but important detail for adjusting figure size on a one-off basis (as several commenters above reported "this doesn't work for me"):

You should do plt.figure(figsize=(,)) PRIOR to defining your actual plot. For example:

This should correctly size the plot according to your specified figsize:

values = [1,1,1,2,2,3]
_ = plt.figure(figsize=(10,6))
_ = plt.hist(values,bins=3)
plt.show()

Whereas this will show the plot with the default settings, seeming to "ignore" figsize:

values = [1,1,1,2,2,3]
_ = plt.hist(values,bins=3)
_ = plt.figure(figsize=(10,6))
plt.show()

In my situation, I needed to retain unique keys with the array values, so I just used a second array:

$arr1 = array("alpha"=>"bravo","charlie"=>"delta","echo"=>"foxtrot");
unset($arr1);

$arr2 = array();
foreach($arr1 as $key=>$value) $arr2[$key] = $value;
$arr1 = $arr2
unset($arr2);

I think the problem you're having is that your JSON is a list of objects when it comes in and it doesnt directly relate to your root class.

var content would look something like this (i assume):

[
  {
    "id": 3636,
    "is_default": true,
    "name": "Unit",
    "quantity": 1,
    "stock": "100000.00",
    "unit_cost": "0"
  },
  {
    "id": 4592,
    "is_default": false,
    "name": "Bundle",
    "quantity": 5,
    "stock": "100000.00",
    "unit_cost": "0"
  }
]

Note: make use of http://jsonviewer.stack.hu/ to format your JSON.

So if you try the following it should work:

  public static List<RootObject> GetItems(string user, string key, Int32 tid, Int32 pid)
    {
        // Customize URL according to geo location parameters
        var url = string.Format(uniqueItemUrl, user, key, tid, pid);

        // Syncronious Consumption
        var syncClient = new WebClient();

        var content = syncClient.DownloadString(url);

        return JsonConvert.DeserializeObject<List<RootObject>>(content);

    }

You will need to then iterate if you don't wish to return a list of RootObject.

I went ahead and tested this in a Console app, worked fine.

Beyond compare allows you to do that and much more.

It's one of those tools I can't live without.
Take a look here for a reference on the scripting options

You can "style echo" with adding new HTML code.

echo '<span class="city">' . $ip['cityName'] . '</span>';

I have used ajax load to do this:

$('#user_content').load('@Url.Action("UserDetails","User")');

Just for completion, this is the code from google guava library. It is not my code, but I think it is valueable to show it here in this thread.

  /** Maximum loop count when creating temp directories. */

  public static File createTempDir() {
    File baseDir = new File(System.getProperty("java.io.tmpdir"));
    String baseName = System.currentTimeMillis() + "-";

    for (int counter = 0; counter < TEMP_DIR_ATTEMPTS; counter++) {
      File tempDir = new File(baseDir, baseName + counter);
      if (tempDir.mkdir()) {
        return tempDir;
      }
    }
    throw new IllegalStateException(
        "Failed to create directory within "
            + TEMP_DIR_ATTEMPTS

            + "0 to "

            + ')');
  }

not really. Server side code is happening on the server--- you can use javascript to display something to the user on the client side, but it obviously will only execute on the client side. This is the nature of a client server web technology. You're basically disconnected from the server when you get your response.

$(document).ready(function() {
    $('#id').focus();
});

According to this snippet here, this approach should be good for long strings:

private string StringToHex(string hexstring)
{
    StringBuilder sb = new StringBuilder();
    foreach (char t in hexstring)
    { 
        //Note: X for upper, x for lower case letters
        sb.Append(Convert.ToInt32(t).ToString("x")); 
    }
    return sb.ToString();
}

usage:

string result = StringToHex("Hello world"); //returns "48656c6c6f20776f726c64"

Another approach in one line

string input = "Hello world";
string result = String.Concat(input.Select(x => ((int)x).ToString("x")));

The simplest solution would be to use Pillow lib:

from PIL import Image

image = Image.fromarray(<your_numpy_array>.astype(np.uint8))

And you can use it as an image.

ary.GetLength(0) 
ary.GetLength(1)

for 2 dimensional array

The following CSS changes in bold (plus a bunch of content in the columns to test scrolling) will work. See the result in this Pen.

.content { flex: 1; display: flex; height: 1px; }

.column { padding: 20px; border-right: 1px solid #999; overflow: auto; }

The trick seems to be that a scrollable panel needs to have a height literally set somewhere (in this case, via its parent), not just determined by flexbox. So even height: 1px works. The flex-grow:1 will still size the panel to fit properly.

This solution works for me

var DELAY = 250, clicks = 0, timer = null;

$(".fc-event").click(function(e) {
    if (timer == null) {
        timer = setTimeout(function() {
           clicks = 0;
            timer = null;
            // single click code
        }, DELAY);
    }

    if(clicks === 1) {
         clearTimeout(timer);
         timer = null;
         clicks = -1;
         // double click code
    }
    clicks++;
});

Do you want the server name? Or the host name?

Request.Url.Host ala Stephen

Dns.GetHostName - Server name

Request.Url will have access to most everything you'll need to know about the page being requested.

I guess you want to do this:

$total_rating_count = count($total_rating_count);
if ($total_rating_count > 0) // because you can't divide through zero
   $avg = round($total_rating_points / $total_rating_count, 1);

You can use column indices (letters) like this:

import pandas as pd
import numpy as np
file_loc = "path.xlsx"
df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")
print(df)

[Corresponding documentation][1]:

usecolsint, str, list-like, or callable default None

• If None, then parse all columns.
• If str, then indicates comma separated list of Excel column letters and column ranges (e.g. “A:E” or “A,C,E:F”). Ranges are inclusive of both sides.
• If list of int, then indicates list of column numbers to be parsed.

• If list of string, then indicates list of column names to be parsed.

  New in version 0.24.0.

• If callable, then evaluate each column name against it and parse the column if the callable returns True.

Returns a subset of the columns according to behavior above.

New in version 0.24.0.

Python doesn't really have either concept.

It uses duck typing, which removed the need for interfaces (at least for the computer :-))

Python <= 2.5: Base classes obviously exist, but there is no explicit way to mark a method as 'pure virtual', so the class isn't really abstract.

Python >= 2.6: Abstract base classes do exist (http://docs.python.org/library/abc.html). And allow you to specify methods that must be implemented in subclasses. I don't much like the syntax, but the feature is there. Most of the time it's probably better to use duck typing from the 'using' client side.

1. go to the master branch our-team

   • git checkout our-team

2. pull all the new changes from our-team branch

   • git pull

3. go to your branch featurex

   • git checkout featurex

4. merge the changes of our-team branch into featurex branch

   • git merge our-team
   • or git cherry-pick {commit-hash} if you want to merge specific commits

5. push your changes with the changes of our-team branch

   • git push

Note: probably you will have to fix conflicts after merging our-team branch into featurex branch before pushing

While many people here say there is no best way for object creation, there is a rationale as to why there are so many ways to create objects in JavaScript, as of 2019, and this has to do with the progress of JavaScript over the different iterations of EcmaScript releases dating back to 1997.

Prior to ECMAScript 5, there were only two ways of creating objects: the constructor function or the literal notation ( a better alternative to new Object()). With the constructor function notation you create an object that can be instantiated into multiple instances (with the new keyword), while the literal notation delivers a single object, like a singleton.

// constructor function
function Person() {};

// literal notation
var Person = {};

Regardless of the method you use, JavaScript objects are simply properties of key value pairs:

// Method 1: dot notation
obj.firstName = 'Bob';

// Method 2: bracket notation. With bracket notation, you can use invalid characters for a javascript identifier.
obj['lastName'] = 'Smith';

// Method 3: Object.defineProperty
Object.defineProperty(obj, 'firstName', {
    value: 'Bob',
    writable: true,
    configurable: true,
    enumerable: false
})

// Method 4: Object.defineProperties
Object.defineProperties(obj, {
  firstName: {
    value: 'Bob',
    writable: true
  },
  lastName: {
    value: 'Smith',
    writable: false
  }
});

In early versions of JavaScript, the only real way to mimic class-based inheritance was to use constructor functions. the constructor function is a special function that is invoked with the 'new' keyword. By convention, the function identifier is capitalized, albiet it is not required. Inside of the constructor, we refer to the 'this' keyword to add properties to the object that the constructor function is implicitly creating. The constructor function implicitly returns the new object with the populated properties back to the calling function implicitly, unless you explicitly use the return keyword and return something else.

function Person(firstName, lastName) {
    this.firstName = firstName;
    this.lastName = lastName;

    this.sayName = function(){
        return "My name is " + this.firstName + " " + this.lastName;
    }
} 

var bob = new Person("Bob", "Smith");
bob instanceOf Person // true

There is a problem with the sayName method. Typically, in Object-Oriented Class-based programming languages, you use classes as factories to create objects. Each object will have its own instance variables, but it will have a pointer to the methods defined in the class blueprint. Unfortunately, when using JavaScript's constructor function, every time it is called, it will define a new sayName property on the newly created object. So each object will have its own unique sayName property. This will consume more memory resources.

In addition to increased memory resources, defining methods inside of the constructor function eliminates the possibility of inheritance. Again, the method will be defined as a property on the newly created object and no other object, so inheritance cannot work like. Hence, JavaScript provides the prototype chain as a form of inheritance, making JavaScript a prototypal language.

If you have a parent and a parent shares many properties of a child, then the child should inherit those properties. Prior to ES5, it was accomplished as follows:

function Parent(eyeColor, hairColor) {
    this.eyeColor = eyeColor;
    this.hairColor = hairColor;
}

Parent.prototype.getEyeColor = function() {
  console.log('has ' + this.eyeColor);
}

Parent.prototype.getHairColor = function() {
  console.log('has ' + this.hairColor);
}

function Child(firstName, lastName) {
  Parent.call(this, arguments[2], arguments[3]);
  this.firstName = firstName;
  this.lastName = lastName;
}

Child.prototype = Parent.prototype;

var child = new Child('Bob', 'Smith', 'blue', 'blonde');
child.getEyeColor(); // has blue eyes
child.getHairColor(); // has blonde hair

The way we utilized the prototype chain above has a quirk. Since the prototype is a live link, by changing the property of one object in the prototype chain, you'd be changing same property of another object as well. Obviously, changing a child's inherited method should not change the parent's method. Object.create resolved this issue by using a polyfill. Thus, with Object.create, you can safely modify a child's property in the prototype chain without affecting the parent's same property in the prototype chain.

ECMAScript 5 introduced Object.create to solve the aforementioned bug in the constructor function for object creation. The Object.create() method CREATES a new object, using an existing object as the prototype of the newly created object. Since a new object is created, you no longer have the issue where modifying the child property in the prototype chain will modify the parent's reference to that property in the chain.

var bobSmith = {
    firstName: "Bob",
    lastName: "Smith",
    sayName: function(){
      return "My name is " + this.firstName + " " + this.lastName;
    }
}

var janeSmith = Object.create(bobSmith, {
    firstName : {  value: "Jane" }
})

console.log(bobSmith.sayName()); // My name is Bob Smith
console.log(janeSmith.sayName()); // My name is Jane Smith
janeSmith.__proto__ == bobSmith; // true
janeSmith instanceof bobSmith; // Uncaught TypeError: Right-hand side of 'instanceof' is not callable. Error occurs because bobSmith is not a constructor function.

Prior to ES6, here was a common creational pattern to utilize function constructors and Object.create:

const View = function(element){
  this.element = element;
}

View.prototype = {
  getElement: function(){
    this.element
  }
}

const SubView = function(element){
  View.call(this, element);
}

SubView.prototype = Object.create(View.prototype);

Now Object.create coupled with constructor functions have been widely used for object creation and inheritance in JavaScript. However, ES6 introduced the concept of classes, which are primarily syntactical sugar over JavaScript's existing prototype-based inheritance. The class syntax does not introduce a new object-oriented inheritance model to JavaScript. Thus, JavaScript remains a prototypal language.

ES6 classes make inheritance much easier. We no longer have to manually copy the parent class's prototype functions and reset the child class's constructor.

// create parent class
class Person {
  constructor (name) {
    this.name = name;
  }
}

// create child class and extend our parent class
class Boy extends Person {
  constructor (name, color) {
    // invoke our parent constructor function passing in any required parameters
    super(name);

    this.favoriteColor = color;
  }
}

const boy = new Boy('bob', 'blue')
boy.favoriteColor; // blue

All in all, these 5 different strategies of Object Creation in JavaScript coincided the evolution of the EcmaScript standard.

Using something like self-clearing div is perfect for a situation like this. Then you'll just use a class on the parent... like:

<div id="parent" class="clearfix">

Just connect the device to the PC with a USB cable, then copy the .apk file to the device. On the device, touch the APK file in the file explorer to install it.

You could also offer the .apk on your website. People can download it, then touch it to install.

You have the right idea, except a more precise timing is available with the microtime() function.

If what is inside the loop is fast, it is possible that the apparent elapsed time will be zero. If so, wrap another loop around the code and call it repeatedly. Be sure to divide the difference by the number of iterations to get a per-once time. I have profiled code which required 10,000,000 iterations to get consistent, reliable timing results.

Similar to accepted answer with one less step:

$my_value = 'Test me more';
$first_word = explode(' ',trim($my_value))[0];

//$first_word == 'Test'

The rebinding behaviour mentioned in other answers does matter in certain circumstances:

>>> a = ([],[])
>>> a[0].append(1)
>>> a
([1], [])
>>> a[1] += [1]
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
TypeError: 'tuple' object does not support item assignment

That's because augmented assignment always rebinds, even if the object was mutated in-place. The rebinding here happens to be a[1] = *mutated list*, which doesn't work for tuples.

In order to execute multiple programs, I also needed a profiles section:

<profiles>
  <profile>
    <id>traverse</id>
    <activation>
      <property>
        <name>traverse</name>
      </property>
    </activation>
    <build>
      <plugins>
        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>exec-maven-plugin</artifactId>
          <configuration>
            <executable>java</executable>
            <arguments>
              <argument>-classpath</argument>
              <argument>org.dhappy.test.NeoTraverse</argument>
            </arguments>
          </configuration>
        </plugin>
      </plugins>
    </build>
  </profile>
</profiles>

This is then executable as:

mvn exec:exec -Ptraverse

There's a free php script made by Celeron Dude that can do this called Celeron Dude Indexer 2. It doesn't require .htaccess The source code is easy to understand and provides a good starting point.

Here's a download link: https://gitlab.com/desbest/celeron-dude-indexer/

You can use this:

$(document).ready(function() {
    $("#tabs").tabs();
    $('#action').click(function() {
        var selected = $("#tabs").tabs("option", "selected");
        $("#tabs").tabs("option", "selected", selected + 1);
    });
});

Also consider changing the input type as button instead of submit unless you want to submit the page.

The STL's philosophy is that you choose a container based on guarantees and not based on how the container is implemented. For example, your choice of container may be based on a need for fast lookups. For all you care, the container may be implemented as a unidirectional list -- as long as searching is very fast you'd be happy. That's because you're not touching the internals anyhow, you're using iterators or member functions for the access. Your code is not bound to how the container is implemented but to how fast it is, or whether it has a fixed and defined ordering, or whether it is efficient on space, and so on.

UPDATE

A more direct jQuery method to the option selected would be:

var selected_option = $('#mySelectBox option:selected');

Answering the question .is(':selected') is what you are looking for:

$('#mySelectBox option').each(function() {
    if($(this).is(':selected')) ...

The non jQuery (arguably best practice) way to do it would be:

$('#mySelectBox option').each(function() {
    if(this.selected) ...

Although, if you are just looking for the selected value try:

$('#mySelectBox').val()

If you are looking for the selected value's text do:

$('#mySelectBox option').filter(':selected').text();

Check out: http://api.jquery.com/selected-selector/

Next time look for duplicate SO questions:

Get current selected option or Set selected option or How to get $(this) selected option in jQuery? or option[selected=true] doesn't work

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

I believe this article say a lot about how sticky works

How CSS Position Sticky Really Works! CSS position sticky has two main parts, sticky item & sticky container.

Sticky Item — is the element that we defined with the position: sticky styles. The element will float when the viewport position matches the position definition, for example: top: 0px .

Sticky Container —is the HTML element which wraps the sticky item. This is the maximum area that the sticky item can float in.

When you define an element with position: sticky you’re automatically defining the parent element as a sticky container!

For completeness:

Along the lines of Chase's answer, I usually use as.data.frame to coerce the matrix to a data.frame:

m <- as.data.frame(matrix(0, ncol = 30, nrow = 2))

EDIT: speed test data.frame vs. as.data.frame

system.time(replicate(10000, data.frame(matrix(0, ncol = 30, nrow = 2))))
   user  system elapsed 
  8.005   0.108   8.165 

system.time(replicate(10000, as.data.frame(matrix(0, ncol = 30, nrow = 2))))
   user  system elapsed 
  3.759   0.048   3.802 

Yes, it appears to be faster (by about 2 times).

I connected to a VPN and it worked. I was using school's WiFi.

You can also do

new List<string>() { "string here" };

111 means connection refused, which in turn means that your mysqld only listens to the localhost interface.

To alter it you may want to look at the bind-address value in the mysqld section of your my.cnf file.

Have a try on the listings package. Here is an example of what I used some time ago to have a coloured Java listing:

\usepackage{listings}

[...]

\lstset{language=Java,captionpos=b,tabsize=3,frame=lines,keywordstyle=\color{blue},commentstyle=\color{darkgreen},stringstyle=\color{red},numbers=left,numberstyle=\tiny,numbersep=5pt,breaklines=true,showstringspaces=false,basicstyle=\footnotesize,emph={label}}

[...]

\begin{lstlisting}
public void here() {
    goes().the().code()
}

[...]

\end{lstlisting}

You may want to customize that. There are several references of the listings package. Just google them.

URL-encoding variables using only AngularJS services

With AngularJS 1.4 and up, two services can handle the process of url-encoding data for POST requests, eliminating the need to manipulate the data with transformRequest or using external dependencies like jQuery:

1. $httpParamSerializerJQLike - a serializer inspired by jQuery's .param() (recommended)

2. $httpParamSerializer - a serializer used by Angular itself for GET requests

Example usage

$http({
  url: 'some/api/endpoint',
  method: 'POST',
  data: $httpParamSerializerJQLike($scope.appForm.data), // Make sure to inject the service you choose to the controller
  headers: {
    'Content-Type': 'application/x-www-form-urlencoded' // Note the appropriate header
  }
}).then(function(response) { /* do something here */ });

See a more verbose Plunker demo

How are $httpParamSerializerJQLike and $httpParamSerializer different

In general, it seems $httpParamSerializer uses less "traditional" url-encoding format than $httpParamSerializerJQLike when it comes to complex data structures.

For example (ignoring percent encoding of brackets):

• Encoding an array

{sites:['google', 'Facebook']} // Object with array property

sites[]=google&sites[]=facebook // Result with $httpParamSerializerJQLike

sites=google&sites=facebook // Result with $httpParamSerializer

• Encoding an object

{address: {city: 'LA', country: 'USA'}} // Object with object property

address[city]=LA&address[country]=USA // Result with $httpParamSerializerJQLike

address={"city": "LA", country: "USA"} // Result with $httpParamSerializer

You should implement the IEnumerable interface (CarBootSaleList should impl it in your case).

Your code also seems a bit strange, like you are nesting lists?

* for python 2.x *

Use a trailing comma to avoid a newline.

print "Hey Guys!",
print "This is how we print on the same line."

The output for the above code snippet would be,

Hey Guys! This is how we print on the same line.

* for python 3.x *

for i in range(10):
    print(i, end="<separator>") # <separator> = \n, <space> etc.

The output for the above code snippet would be (when <separator> = " "),

0 1 2 3 4 5 6 7 8 9

Here is the function which help you

private void saveBitmap(Bitmap bitmap,String path){
        if(bitmap!=null){
            try {
                FileOutputStream outputStream = null;
                try {
                    outputStream = new FileOutputStream(path); //here is set your file path where you want to save or also here you can set file object directly

                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream); // bitmap is your Bitmap instance, if you want to compress it you can compress reduce percentage
                    // PNG is a lossless format, the compression factor (100) is ignored
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    try {
                        if (outputStream != null) {
                            outputStream.close();
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }    
        }
    }

This can have different reasons like:

• You are using an incorrect password
• The MySQL server got an error when trying to resolve the IP address of the client host to a name
• No privileges are granted to the user

You can try one of the following steps:

To reset the password for the remote user by:

SET PASSWORD FOR some_user@ip_addr_of_remote_client=PASSWORD('some_password');

To grant access to the user by:

GRANT SELECT, INSERT, UPDATE, DELETE, LOCK TABLES ON YourDB.* TO user@Host IDENTIFIED by 'password';

Hope this helps you, if not then you will have to go through the documentation

There are multiple ways to share data between controllers

• Angular services
• $broadcast, $emit method
• Parent to child controller communication
• $rootscope

As we know $rootscope is not preferable way for data transfer or communication because it is a global scope which is available for entire application

For data sharing between Angular Js controllers Angular services are best practices eg. .factory, .service
For reference

In case of data transfer from parent to child controller you can directly access parent data in child controller through $scope
If you are using ui-router then you can use $stateParmas to pass url parameters like id, name, key, etc

$broadcast is also good way to transfer data between controllers from parent to child and $emit to transfer data from child to parent controllers

HTML

<div ng-controller="FirstCtrl">
   <input type="text" ng-model="FirstName">
   <br>Input is : <strong>{{FirstName}}</strong>
</div>

<hr>

<div ng-controller="SecondCtrl">
   Input should also be here: {{FirstName}}
</div>

JS

myApp.controller('FirstCtrl', function( $rootScope, Data ){
    $rootScope.$broadcast('myData', {'FirstName': 'Peter'})
});

myApp.controller('SecondCtrl', function( $rootScope, Data ){
    $rootScope.$on('myData', function(event, data) {
       $scope.FirstName = data;
       console.log(data); // Check in console how data is coming
    });
});

Refer given link to know more about $broadcast

An option which doesn't require a subshell and is built in to bash

Also make sure the aspx page has AutoEventWireup="true" and not AutoEventWireup="false"

You could use the or operator:

return x or "default"

Note that this also returns "default" if x is any falsy value, including an empty list, 0, empty string, or even datetime.time(0) (midnight).

According to the below scenario ,

Let's say that someone makes a request to your server with data that is in the correct format, but is simply not "good" data. So for example, imagine that someone posted a String value to an API endpoint that expected a String value; but, the value of the string contained data that was blacklisted (ex. preventing people from using "password" as their password). then the status code could be either 400 or 422 ?

Until now, I would have returned a "400 Bad Request", which, according to the w3.org, means:

The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications.

This description doesn't quite fit the circumstance; but, if you go by the list of core HTTP status codes defined in the HTTP/1.1 protocol, it's probably your best bet.

Recently, however, Someone from my Dev team pointed out [to me] that popular APIs are starting to use HTTP extensions to get more granular with their error reporting. Specifically, many APIs, like Twitter and Recurly, are using the status code "422 Unprocessable Entity" as defined in the HTTP extension for WebDAV. HTTP status code 422 states:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

Going back to our password example from above, this 422 status code feels much more appropriate. The server understands what you're trying to do; and it understands the data that you're submitting; it simply won't let that data be processed.

Here is a alternative solution that should survive if the client pc goes into sleep mode.

If you have a huge amount of logged in users then use this cautiously as this could eat a lot of server memory.

After you login (i do this in the LoggedIn event of the login control)

Dim loggedOutAfterInactivity As Integer = 999 'Minutes

'Keep the session alive as long as the authentication cookie.
Session.Timeout = loggedOutAfterInactivity

'Get the authenticationTicket, decrypt and change timeout and create a new one.
Dim formsAuthenticationTicketCookie As HttpCookie = _
        Response.Cookies(FormsAuthentication.FormsCookieName)

Dim ticket As FormsAuthenticationTicket = _
        FormsAuthentication.Decrypt(formsAuthenticationTicketCookie.Value)
Dim newTicket As New FormsAuthenticationTicket(
        ticket.Version, ticket.Name, ticket.IssueDate, 
        ticket.IssueDate.AddMinutes(loggedOutAfterInactivity), 
        ticket.IsPersistent, ticket.UserData)
formsAuthenticationTicketCookie.Value = FormsAuthentication.Encrypt(newTicket)

From documentation:

Matplotlib can only read PNGs natively. Further image formats are supported via the optional dependency on Pillow.

So in case of PNG we may use plt.imread(). In other cases it's probably better to use Pillow directly.

I found a easy solution: make the tag " li "be inside the tag " a ":

    print(fin.read())

Important thing to be noticed:

Difference between Replace and Replace with backstack is whenever we use only replace then the fragment is destroyed ( ondestroy() is called ) and when we use replace with backstack then fragments onDestroy() is not called ( i.e when back button is pressed fragment is invoked with its onCreateView())

worked for me. thanks.

I added the following to the manifest for that activity

android:configChanges="keyboardHidden|orientation|screenLayout"

This error can be received but be aware it can be a red herring to the real issue. In my case, there wasn't an issue with the JSON as the error states, but rather a 404 was occurring that it could not pull the JSON data to process in the 1st place thus resulting in this error.

The fix for this was that in order to use fetch on a .json file in a local project, the .json file must be accessible. This can be done by placing it in a folder such as the public folder in the root of the project. Once I moved the json file into that folder, the 404 turned into a 200, and the Unexpected token < in JSON at position 0 error was resolved.

This works for me (I'm using mac). Run this command

lsof -PiTCP -sTCP:LISTEN

This's going to display a list of ports that your syetem is using. Find the PID that your node is running

COMMAND     PID          USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME

node      17269 hientrq   19u  IPv4 0xc42959c71ae86fc1      0t0  TCP localhost:1337 (LISTEN)

and run kill -9 [YOUR_PID]

Just wanted to add my 2 cents, since I googled this question b/c I found myself in a similar situation...

BE AWARE that while changing from varchar(xxx) to varchar(yyy) is a meta-data change indeed, but changing to varchar(max) is not. Because varchar(max) values (aka BLOB values - image/text etc) are stored differently on the disk, not within a table row, but "out of row". So the server will go nuts on a big table and become unresponsive for minutes (hours).

--no downtime
ALTER TABLE MyTable ALTER COLUMN [MyColumn] VARCHAR(1200)

--huge downtime
ALTER TABLE MyTable ALTER COLUMN [MyColumn] VARCHAR(max)

PS. same applies to nvarchar or course.

Better way, you can also use EditText onFocusChange listener to check whether user has done editing: (Need not rely on user pressing the Done or Enter button on Soft keyboard)

 ((EditText)findViewById(R.id.youredittext)).setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {

      // When focus is lost check that the text field has valid values.

      if (!hasFocus) { {
         // Validate youredittext
      }
    }
 });

Note : For more than one EditText, you can also let your class implement View.OnFocusChangeListener then set the listeners to each of you EditText and validate them as below

((EditText)findViewById(R.id.edittext1)).setOnFocusChangeListener(this);
((EditText)findViewById(R.id.edittext2)).setOnFocusChangeListener(this);

    @Override
    public void onFocusChange(View v, boolean hasFocus) {

      // When focus is lost check that the text field has valid values.

      if (!hasFocus) {
        switch (view.getId()) {
           case R.id.edittext1:

Starting from AngularJS v1.4.8, you can use get(url, config) as follows:

var data = {
 user_id:user.id
};

var config = {
 params: data,
 headers : {'Accept' : 'application/json'}
};

$http.get(user.details_path, config).then(function(response) {
   // process response here..
 }, function(response) {
});

Qt works very well with graphics. In my opinion it is more versatile than PIL.

You get all the features you want for graphics manipulation, but there's also vector graphics and even support for real printers. And all of that in one uniform API, QPainter.

To use Qt you need a Python binding for it: PySide or PyQt4.
They both support Python 3.

Here is a simple example that loads a JPG image, draws an antialiased circle of radius 10 at coordinates (20, 20) with the color of the pixel that was at those coordinates and saves the modified image as a PNG file:

from PySide.QtCore import *
from PySide.QtGui import *

app = QCoreApplication([])

img = QImage('input.jpg')

g = QPainter(img)
g.setRenderHint(QPainter.Antialiasing)
g.setBrush(QColor(img.pixel(20, 20)))
g.drawEllipse(QPoint(20, 20), 10, 10)
g.end()

img.save('output.png')

But please note that this solution is quite 'heavyweight', because Qt is a large framework for making GUI applications.

emulator-arm.exe error, couldn't run. Problem was that my laptop has 2 graphic cards and was selected only one (the performance one) from Nvidia 555M. By selecting the other graphic card from Nvidia mediu,(selected base Intel card) the emulator started!

I had the same need (to test my angularjs app), and the only way I found is to use require.js:

var json = require('./data.json'); //(with path)

note: the file is loaded once, further calls will use the cache.

ORDER BY a date type does not depend on the date format, the date format is only for showing, in the database, they are same data.

Description

Assuming i understand your question.

You can get the selected row using the DataGridView.SelectedRows Collection. If your DataGridView allows only one selected, have a look at my sample.

DataGridView.SelectedRows Gets the collection of rows selected by the user.

Sample

if (dataGridView1.SelectedRows.Count != 0)
{
    DataGridViewRow row = this.dataGridView1.SelectedRows[0];
    row.Cells["ColumnName"].Value
}

More Information

• MSDN - DataGridView.SelectedRows Property

This function working well,

function validateDate($date, $format = 'm/d/Y'){
    $d = DateTime::createFromFormat($format, $date);
    return $d && $d->format($format) === $date;
}

And if you have lot insert queries but not wanna ger a ERROR message everytime , you can do it:

CREATE UNIQUE NONCLUSTERED INDEX SK01 ON dbo.Person(ID,Name,Active,PersonNumber) 
WITH(IGNORE_DUP_KEY = ON)

Use the Date object's getTime() method, which returns the number of milliseconds since 1 January 1970 00:00:00 UTC (epoch time):

var date = new Date();
var copiedDate = new Date(date.getTime());

In Safari 4, you can also write:

var date = new Date();
var copiedDate = new Date(date);

...but I'm not sure whether this works in other browsers. (It seems to work in IE8).

Our git repo disk is mounted on AIX box to do BUILD.

It sounds like you mounted the drive on which the git repository is stored on another server, and you are asking how to modify that. If that is the case, this is a bad idea.

The build server should have its own copy of the git repository, and it will be locally managed by git on the build server. The build server's repository will be connected to the "main" git repository with a "remote", and you can issue the command git pull to update the local repository on the build server.

If you don't want to go to the trouble of setting up SSH or a gitolite server or something similar, you can use a file path as the "remote" location. So you could continue to mount the Linux server's file system on the build server, but instead of running the build out of that mounted path, clone the repository into another folder and run it from there.

Also worth noting window.scrollBy(dx,dy) (ref)

Call this method:

public static void shareApp(Context context)
{
    final String appPackageName = context.getPackageName();
    Intent sendIntent = new Intent();
    sendIntent.setAction(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_TEXT, "Check out the App at: https://play.google.com/store/apps/details?id=" + appPackageName);
    sendIntent.setType("text/plain");
    context.startActivity(sendIntent);
}

As far as I can see, you just added heredoc by mistake
No need to use ugly heredoc syntax here.
Just remove it and everything will work:

<p>Hello</p>
<p><?= _("World"); ?></p>

The reason os.path.join('C:', 'src') is not working as you expect is because of something in the documentation that you linked to:

Note that on Windows, since there is a current directory for each drive, os.path.join("c:", "foo") represents a path relative to the current directory on drive C: (c:foo), not c:\foo.

As ghostdog said, you probably want mypath=os.path.join('c:\\', 'sourcedir')

try this

   SELECT group_name, employees, surveys, COUNT( surveys ) AS test1, 
        concat(round(( surveys/employees * 100 ),2),'%') AS percentage
    FROM a_test
    GROUP BY employees

DEMO HERE

A quick trick to use for me is using the find duplicates query SQL and changing 1 to 0 in Having expression. Like this:

SELECT COUNT([UniqueField]) AS DistinctCNT FROM
(
  SELECT First([FieldName]) AS [UniqueField]
  FROM TableName
  GROUP BY [FieldName]
  HAVING (((Count([FieldName]))>0))
);

Hope this helps, not the best way I am sure, and Access should have had this built in.

The return statements should place in one line. Or the other option is to remove the curly brackets that bound the HTML statement.

example:

return posts.map((post, index) =>
    <div key={index}>
      <h3>{post.title}</h3>
      <p>{post.body}</p>
    </div>
);

In objective-C, go ahead and create a category method off of the UIView class.

- (void)removeAllSubviews
{
    for (UIView *subview in self.subviews)
        [subview removeFromSuperview];
}

int main()
{
    unsigned long long d;
    scanf("%llu",&d);
    printf("%llu",d);
    getch();
}

This will be helpful . . .

you can use the following code:

if(Platform.Equals("WinCE"))
{
    m_CurrentPath = Path.GetDirectoryName(Assembly.GetExecutingAssembly().GetName().CodeBase);
}
else if(Platform.Equals("Win32NT"))
{
    m_CurrentPath = Directory.GetCurrentDirectory();
}

If you really want to use regex, then

>>> df.replace('(^\s+|\s+$)', '', regex=True, inplace=True)
>>> df

0  a  10

But it should be faster to do it like this:

>>> df[0] = df[0].str.strip()

I was on the GM seed of Xcode 5.0 and I couldn't get any of these answers to work. I tried every single answer on SO on multiple different questions about header imports w/ cocoapods.

FINALLY I found a solution that worked for me: I upgraded to Xcode 5.0 via the Mac AppStore (installed on top of the GM seed) and now the header imports are working as expected.

I also still had a beta version of Xcode 5 on my system and I deleted that as well. Maybe it was a combination of the two things, but hopefully this helps someone else.

Maybe a bit late to answer but i would like to share my way. I found an easy way with threads in the main program for a winform application.

Lets say you have your form "splashscreen" with an animation, and your "main" which has all your application code.

 [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Thread mythread;
        mythread = new Thread(new ThreadStart(ThreadLoop));
        mythread.Start();
        Application.Run(new MainForm(mythread));           
    }

    public static void ThreadLoop()
    {
        Application.Run(new SplashScreenForm());           
    }

In your main form in the constructor:

 public MainForm(Thread splashscreenthread)
    {
        InitializeComponent();

        //add your constructor code

        splashscreenthread.Abort();            
    }

This way the splashscreen will last just the time for your main form to load.

Your splashcreen form should have his own way to animate/display information. In my project my splashscreen start a new thread, and every x milliseconds it changes his main picture to another which is a slightly different gear, giving the illusion of a rotation.

example of my splashscreen:

int status = 0;
private bool IsRunning = false;
    public Form1()
    {
        InitializeComponent();
        StartAnimation();
    }

    public void StartAnimation()
    {
        backgroundWorker1.WorkerReportsProgress = false;
        backgroundWorker1.WorkerSupportsCancellation = true;
        IsRunning = true;
        backgroundWorker1.RunWorkerAsync();
    }


    public void StopAnimation()
    {
        backgroundWorker1.CancelAsync();
    }

    delegate void UpdatingThreadAnimation();
    public void UpdateAnimationFromThread()
    {

        try
        {
            if (label1.InvokeRequired == false)
            {
                UpdateAnimation();
            }
            else
            {
                UpdatingThreadAnimation d = new UpdatingThreadAnimation(UpdateAnimationFromThread);
                this.Invoke(d, new object[] { });
            }
        }
        catch(Exception e)
        {

        }
    }

 private void UpdateAnimation()
    {
    if(status ==0) 
    {
    // mypicture.image = image1
     }else if(status ==1)
     {
    // mypicture.image = image2
     }
    //doing as much as needed

      status++;
        if(status>1) //change here if you have more image, the idea is to set a cycle of images
        {
            status = 0;
        }
        this.Refresh();
    }

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
    {
        BackgroundWorker worker = sender as BackgroundWorker;
        while (IsRunning == true)
        {
            System.Threading.Thread.Sleep(100);
            UpdateAnimationFromThread();
        }
    }

Hope this will help some people. Sorry if i have made some mistakes. English is not my first language.

Slight modification to the accepted answer.

def resource_path(relative_path):
    """ Get absolute path to resource, works for dev and for PyInstaller """

None of the existing answers quite offers a simple solution that returns "the number of rows that are just duplicates and should be cut out". This is a one-size-fits-all solution that does:

# generate a table of those culprit rows which are duplicated:
dups = df.groupby(df.columns.tolist()).size().reset_index().rename(columns={0:'count'})

# sum the final col of that table, and subtract the number of culprits:
dups['count'].sum() - dups.shape[0]

run:

rbenv init

After I ran that, when i set my local rbenv version:

rbenv local 2.4.0

then my ruby -v and my rbenv local versions coincided.

Note: You might also want to exit the directory you're in and then go back into it, i've noticed that was necessary for me in order to get things to work.

Use:

$(document.body).addClass('about');

Use preg_replace() and instead of [ \t\n\r] use \s:

$output = preg_replace('!\s+!', ' ', $input);

From Regular Expression Basic Syntax Reference:

\d, \w and \s

Shorthand character classes matching digits, word characters (letters, digits, and underscores), and whitespace (spaces, tabs, and line breaks). Can be used inside and outside character classes.

If you have to disable SSL checks for one git server hosting several repositories, you can run :

git config --bool --add http.https://my.bad.server.sslverify false

This will add it to your user's configuration.

Command to check:

git config --bool --get-urlmatch http.sslverify https://my.bad.server 

(If you still use git < v1.8.5, run git config --global http.https://my.bad.server.sslVerify false)

Explanation from the documentation where the command is at the end, show the .gitconfig content looking like:

[http "https://my.bad.server"]
        sslVerify = false

It will ignore any certificate checks for this server, whatever the repository.

You also have some explanation in the code

Since this is about REST, just getting the request method from the server is not enough. You also need to receive RESTful route parameters. The reason for separating RESTful parameters and GET/POST/PUT parameters is that a resource needs to have its own unique URL for identification.

Here's one way of implementing RESTful routes in PHP using Slim:

https://github.com/codeguy/Slim

$app = new \Slim\Slim();
$app->get('/hello/:name', function ($name) {
  echo "Hello, $name";
});
$app->run();

And configure the server accordingly.

Here's another example using AltoRouter:

https://github.com/dannyvankooten/AltoRouter

$router = new AltoRouter();
$router->setBasePath('/AltoRouter'); // (optional) the subdir AltoRouter lives in

// mapping routes
$router->map('GET|POST','/', 'home#index', 'home');
$router->map('GET','/users', array('c' => 'UserController', 'a' => 'ListAction'));
$router->map('GET','/users/[i:id]', 'users#show', 'users_show');
$router->map('POST','/users/[i:id]/[delete|update:action]', 'usersController#doAction', 'users_do');

Wrong gradle file. The right one is build.gradle in your 'app' folder.

With the unobtrusive way:

• You don't have to call the validate() method.
• You specify requirements using data attributes (data-val, data-val-required, etc.)

Jquery Validate Example:

<input type="text" name="email" class="required">
<script>
        $(function () {
            $("form").validate();
        });
</script>

Jquery Validate Unobtrusive Example:

<input type="text" name="email" data-val="true" 
data-val-required="This field is required.">  

<div class="validation-summary-valid" data-valmsg-summary="true">
    <ul><li style="display:none"></li></ul>

Quick tweak to @alex-rodrigues answer... deals with shape including the number of channels.

import cv2
import numpy as np

def rotateImage(image, angle):
    center=tuple(np.array(image.shape[0:2])/2)
    rot_mat = cv2.getRotationMatrix2D(center,angle,1.0)
    return cv2.warpAffine(image, rot_mat, image.shape[0:2],flags=cv2.INTER_LINEAR)

Add style="width:100%; height:100%;" to the div see what that does

not to the #map_canvas but the main div

example

<body>
    <div style="height:100%; width:100%;">
         <div id="map-canvas"></div>
    </div>
</body> 

There are some other answers on here the explain why this is necessary

This is what ended up working.

$("select").change(function(){
    $.get("/page.html?" + $(this).parent("form").find(":input").serialize()); 
});

I had the same issue. Project B in my case was a .Net Core Class Library which has a Nuget "Microsoft.Management.Infrastructure" installed. The error was that i called my project B "MI". I changed the project name to something else and suddenly everything worked again.

Is there any solution like building a pdf file on file system in order to let the user download it?

Try setting responseType of XMLHttpRequest to blob , substituting download attribute at a element for window.open to allow download of response from XMLHttpRequest as .pdf file

var request = new XMLHttpRequest();
request.open("GET", "/path/to/pdf", true); 
request.responseType = "blob";
request.onload = function (e) {
    if (this.status === 200) {
        // `blob` response
        console.log(this.response);
        // create `objectURL` of `this.response` : `.pdf` as `Blob`
        var file = window.URL.createObjectURL(this.response);
        var a = document.createElement("a");
        a.href = file;
        a.download = this.response.name || "detailPDF";
        document.body.appendChild(a);
        a.click();
        // remove `a` following `Save As` dialog, 
        // `window` regains `focus`
        window.onfocus = function () {                     
          document.body.removeChild(a)
        }
    };
};
request.send();

Here is an example of iterating over a pd.DataFrame grouped by the column atable. For this sample, "create" statements for an SQL database are generated within the for loop:

import pandas as pd

df1 = pd.DataFrame({
    'atable':     ['Users', 'Users', 'Domains', 'Domains', 'Locks'],
    'column':     ['col_1', 'col_2', 'col_a', 'col_b', 'col'],
    'column_type':['varchar', 'varchar', 'int', 'varchar', 'varchar'],
    'is_null':    ['No', 'No', 'Yes', 'No', 'Yes'],
})

df1_grouped = df1.groupby('atable')

# iterate over each group
for group_name, df_group in df1_grouped:
    print('\nCREATE TABLE {}('.format(group_name))

    for row_index, row in df_group.iterrows():
        col = row['column']
        column_type = row['column_type']
        is_null = 'NOT NULL' if row['is_null'] == 'NO' else ''
        print('\t{} {} {},'.format(col, column_type, is_null))

    print(");")

Yes, it is possible:

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

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

<directory> 

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

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

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

You can sort a list in-place just by calling List<T>.Sort:

list.Sort();

That will use the natural ordering of elements, which is fine in your case.

EDIT: Note that in your code, you'd need

_details.Sort();

as the Sort method is only defined in List<T>, not IList<T>. If you need to sort it from the outside where you don't have access to it as a List<T> (you shouldn't cast it as the List<T> part is an implementation detail) you'll need to do a bit more work.

I don't know of any IList<T>-based in-place sorts in .NET, which is slightly odd now I come to think of it. IList<T> provides everything you'd need, so it could be written as an extension method. There are lots of quicksort implementations around if you want to use one of those.

If you don't care about a bit of inefficiency, you could always use:

public void Sort<T>(IList<T> list)
{
    List<T> tmp = new List<T>(list);
    tmp.Sort();
    for (int i = 0; i < tmp.Count; i++)
    {
        list[i] = tmp[i];
    }
}

In other words, copy, sort in place, then copy the sorted list back.

You can use LINQ to create a new list which contains the original values but sorted:

var sortedList = list.OrderBy(x => x).ToList();

It depends which behaviour you want. Note that your shuffle method isn't really ideal:

• Creating a new Random within the method runs into some of the problems shown here
• You can declare val inside the loop - you're not using that default value
• It's more idiomatic to use the Count property when you know you're working with an IList<T>
• To my mind, a for loop is simpler to understand than traversing the list backwards with a while loop

There are other implementations of shuffling with Fisher-Yates on Stack Overflow - search and you'll find one pretty quickly.

In answer ,it creates circular dependency.This can be avoided by removing parent inside Child nodes. i.e,

public class MyTreeNode<T>{     


    private T data = null;
    private List<MyTreeNode> children = new ArrayList<>();


    public MyTreeNode(T data) {
        this.data = data;

    }

    public void addChild(MyTreeNode child) {
        this.children.add(child);
    }

    public void addChild(T data) {
        MyTreeNode<T> newChild = new MyTreeNode<>(data);
        children.add(newChild);
    }

    public void addChildren(List<MyTreeNode> children) {
        this.children.addAll(children);
    }

    public List<MyTreeNode> getChildren() {
        return children;
    }

    public T getData() {
        return data;
    }

    public void setData(T data) {
        this.data = data;
    }


}

Using the same example specified above,the output will be like this:

{ "data": "Root", "children": [ { "data": "Child1", "children": [ { "data": "Grandchild1", "children": [] }, { "data": "Grandchild2", "children": [] } ] }, { "data": "Child2", "children": [ { "data": "Grandchild3", "children": [] } ] }, { "data": "Child3", "children": [] }, { "data": "Child4", "children": [] }, { "data": "Child5", "children": [] }, { "data": "Child6", "children": [] } ] }

You can't insert comments inside xml tags.

By omitting all parts of the head, the loop can also become infinite:

for (;;) {}

Same as matt said. The "SQL Server(SQLEXPRESS)" was stopped. Enabled it by opening Control Panel > Administrative Tools > Services, right-clicking on the "SQL Server(SQLEXPRESS)" service and selecting "Start" from the available options. Could connect fine after that.

If you set up your file system differently or looking for a different way of setting up a file system and then checking if a file exists in the documents folder heres an another example. also show dynamic checking

for (int i = 0; i < numberHere; ++i){
    NSFileManager* fileMgr = [NSFileManager defaultManager];
    NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
    NSString* imageName = [NSString stringWithFormat:@"image-%@.png", i];
    NSString* currentFile = [documentsDirectory stringByAppendingPathComponent:imageName];
    BOOL fileExists = [fileMgr fileExistsAtPath:currentFile];
    if (fileExists == NO){
        cout << "DOESNT Exist!" << endl;
    } else {
        cout << "DOES Exist!" << endl;
    }
}

there is a start item folder in C:\ drive. Remove ur anaconda3 folder there, simple and you are good to go. In my case I found here "C:\Users\pravu\AppData\Roaming\Microsoft\Windows\Start Menu\Programs"

I believe you are getting an empty array because PHP is expecting the posted data to be in a Querystring format (key=value&key1=value1).

Try changing your curl request to:

curl -i -X POST -d 'json={"screencast":{"subject":"tools"}}'  \
      http://localhost:3570/index.php/trainingServer/screencast.json

and see if that helps any.

If I invoke clone() method on array of Objects of type A, how will it clone its elements?

The elements of the array will not be cloned.

Will the copy be referencing to the same objects?

Yes.

Or will it call (element of type A).clone() for each of them?

No, it will not call clone() on any of the elements.

You missed the second statement: 1) NOT LIKE A, AND 2) NOT LIKE B

SELECT word FROM table WHERE word NOT LIKE '%a%' AND word NOT LIKE '%b%'

This is same as the previous solution but I have defined the function in df.apply itself:

df['Value'] = df.apply(lambda row: row['a']%row['c'], axis=1)

(char)myint;

for example:

Console.WriteLine("(char)122 is {0}", (char)122);

yields:

(char)122 is z

On Linux, you can read from /proc/sys/kernel/random/uuid:

package main

import "io/ioutil"
import "fmt"

func main() {
    u, _ := ioutil.ReadFile("/proc/sys/kernel/random/uuid")
    fmt.Println(string(u))
}

No external dependencies!

$ go run uuid.go

As others have already mentioned, the best way to debug your variables is to use a modern browser's developer console (e.g. Chrome Developer Tools, Firefox+Firebug, Opera Dragonfly _{(which now disappeared in the new Chromium-based (Blink) Opera, but as developers say, "Dragonfly is not dead though we cannot give you more information yet")}.

But in case you need another approach, there's a really useful site called php.js:

http://phpjs.org/

which provides "JavaScript alternatives to PHP functions" - so you can use them the similar way as you would in PHP. I will copy-paste the appropriate functions to you here, BUT be aware that these codes can get updated on the original site in case some bugs are detected, so I suggest you visiting the phpjs.org site! (Btw. I'm NOT affiliated with the site, but I find it extremely useful.)
