You can try using something like this. In this case I used one stored procedure to get more data tables and export all of them using CSV.

using System;
using System.Text;
using System.Data;
using System.Data.SqlClient;
using System.IO;

namespace bo
{
class Program
{
    static private void CreateCSVFile(DataTable dt, string strFilePath)
    {
        #region Export Grid to CSV
        // Create the CSV file to which grid data will be exported.
        StreamWriter sw = new StreamWriter(strFilePath, false);
        int iColCount = dt.Columns.Count;

        // First we will write the headers.

        //DataTable dt = m_dsProducts.Tables[0];
        for (int i = 0; i < iColCount; i++)
        {
            sw.Write(dt.Columns[i]);
            if (i < iColCount - 1)
            {
                sw.Write(";");
            }
        }
        sw.Write(sw.NewLine);

        // Now write all the rows.
        foreach (DataRow dr in dt.Rows)
        {
            for (int i = 0; i < iColCount; i++)
            {
                if (!Convert.IsDBNull(dr[i]))
                {
                    sw.Write(dr[i].ToString());
                }
                if (i < iColCount -1 )
                {
                    sw.Write(";");
                }
            }
            sw.Write(sw.NewLine);
        }
        sw.Close();

        #endregion
    }
    static void Main(string[] args)
    {
        string strConn = "connection string to sql";
        string direktorij = @"d:";
        SqlConnection conn = new SqlConnection(strConn); 
        SqlCommand command = new SqlCommand("sp_ado_pos_data", conn);
        command.CommandType = CommandType.StoredProcedure;
        command.Parameters.Add('@skl_id', SqlDbType.Int).Value = 158;
        SqlDataAdapter adapter = new SqlDataAdapter(command);
        DataSet ds = new DataSet();
        adapter.Fill(ds);
        for (int i = 0; i < ds.Tables.Count; i++)
        {
            string datoteka  = (string.Format(@"{0}tablea{1}.csv", direktorij, i));
            DataTable tabela = ds.Tables[i];
            CreateCSVFile(tabela,datoteka );
            Console.WriteLine("Generišem tabelu {0}", datoteka);
        }

Short & modern

You can catch form input values using FormData and send them by fetch

fetch(form.action, {method:'post', body: new FormData(form)});

function send() {
  let form = document.forms['inputform'];
  fetch(form.action, {method:'post', body: new FormData(form)});
}

<form name="inputform" action="somewhere" method="post">
  <input               value="person" name="user">
  <input type="hidden" value="password" name="pwd">
  <input               value="place" name="organization">
  <input type="hidden" value="key" name="requiredkey">
</form>

<!-- I remove type="hidden" for some inputs above only for show them --><br>
Look: chrome console>network and click <button onclick="send()">send</button>

From MSDN:

Application.Exit

Informs all message pumps that they must terminate, and then closes all application windows after the messages have been processed. This is the code to use if you are have called Application.Run (WinForms applications), this method stops all running message loops on all threads and closes all windows of the application.

Environment.Exit

Terminates this process and gives the underlying operating system the specified exit code. This is the code to call when you are using console application.

This article, Application.Exit vs. Environment.Exit, points towards a good tip:

You can determine if System.Windows.Forms.Application.Run has been called by checking the System.Windows.Forms.Application.MessageLoop property. If true, then Run has been called and you can assume that a WinForms application is executing as follows.

if (System.Windows.Forms.Application.MessageLoop) 
{
    // WinForms app
    System.Windows.Forms.Application.Exit();
}
else
{
    // Console app
    System.Environment.Exit(1);
}

Reference: Why would Application.Exit fail to work?

Here's a comparison of the two:

Entity Type

• SQS: Queue (Similar to JMS)
• SNS: Topic (Pub/Sub system)

Message consumption

• SQS: Pull Mechanism - Consumers poll and pull messages from SQS
• SNS: Push Mechanism - SNS Pushes messages to consumers

Use Case

• SQS: Decoupling two applications and allowing parallel asynchronous processing
• SNS: Fanout - Processing the same message in multiple ways

Persistence

• SQS: Messages are persisted for some (configurable) duration if no consumer is available (maximum two weeks), so the consumer does not have to be up when messages are added to queue.
• SNS: No persistence. Whichever consumer is present at the time of message arrival gets the message and the message is deleted. If no consumers are available then the message is lost after a few retries.

Consumer Type

• SQS: All the consumers are typically identical and hence process the messages in the exact same way (each message is processed once by one consumer, though in rare cases messages may be resent)
• SNS: The consumers might process the messages in different ways

Sample applications

• SQS: Jobs framework: The Jobs are submitted to SQS and the consumers at the other end can process the jobs asynchronously. If the job frequency increases, the number of consumers can simply be increased to achieve better throughput.
• SNS: Image processing. If someone uploads an image to S3 then watermark that image, create a thumbnail and also send a Thank You email. In that case S3 can publish notifications to an SNS topic with three consumers listening to it. The first one watermarks the image, the second one creates a thumbnail and the third one sends a Thank You email. All of them receive the same message (image URL) and do their processing in parallel.

You can use this. Tt is simplest way.

.carousel-item{
    height: 200px;
} 
.carousel-item img{
    height: 200px;
}

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

So, your new line should look like:

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

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

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

+1 way, that works in ksh, dash, etc: use printf to insert TAB:

grep "$(printf 'BEGIN\tEND')" testfile.txt

<span style="color:orange;">orange text</span>

Is the only way I know of barring the font tag.

Something like this would resemble a button:

a.LinkButton {
  border-style: solid;
  border-width : 1px 1px 1px 1px;
  text-decoration : none;
  padding : 4px;
  border-color : #000000
}

See http://jsfiddle.net/r7v5c/1/ for an example.

string.Format("{0:yyyy-MM-ddTHH:mm:ss.FFFZ}", DateTime.UtcNow)

returns 2017-02-10T08:12:39.483Z

Instead of rand(), use newid(), which is recalculated for each row in the result. The usual way is to use the modulo of the checksum. Note that checksum(newid()) can produce -2,147,483,648 and cause integer overflow on abs(), so we need to use modulo on the checksum return value before converting it to absolute value.

UPDATE CattleProds
SET    SheepTherapy = abs(checksum(NewId()) % 10000)
WHERE  SheepTherapy IS NULL

This generates a random number between 0 and 9999.

I accidentally deleted a whole bunch of data in the wrong environment and this post was one of the first ones I found.

Because I was simultaneously panicking and searching for a solution, I went for the first thing I saw - ApexSQL Logs, which was $2000 which was an acceptable cost.

However, I've since found out that Toad for Sql Server can generate undo scripts from transaction logs and it is only $655.

Lastly, found an even cheaper option SysToolsGroup Log Analyzer and it is only $300.

In your classpath you're using an absolute path but you've moved the project onto a new machine with quite possibly a different file structure.

In your classpath you should therefore (and probably in general if you're gonna bundle JARS with your project), use relative pathing:

In your .classpath change

<classpathentry kind="lib" path="C:/Users/Chris/Downloads/last.fm-bindings-0.1.1.jar" sourcepath=""/><classpathentry kind="lib" path="C:/Users/Chris/Downloads/last.fm-bindings-0.1.1.jar" sourcepath=""/>

to

<classpathentry kind="lib" path="last.fm-bindings-0.1.1.jar"/>

I found the method of using the superview's superview to obtain a reference to the cell's indexPath worked perfectly. Thanks to iphonedevbook.com (macnsmith) for the tip link text

-(void)buttonPressed:(id)sender {
 UITableViewCell *clickedCell = (UITableViewCell *)[[sender superview] superview];
 NSIndexPath *clickedButtonPath = [self.tableView indexPathForCell:clickedCell];
...

}

If you happen to have both a bash shell and jad:

JAR=(your jar file name)
unzip -d $JAR.tmp $JAR
pushd $JAR.tmp
for f in `find . -name '*.class'`; do
    jad -d $(dirname $f) -s java -lnc $f
done
popd

I might be a tiny, tiny bit off with that, but it should work more or less as advertised. You should end up with $JAR.tmp containing your decompiled files.

In general case to find out which library dependency has incompatible ABI,

• build an APK file in Android Studio (menu Build > Build Bundle(s)/APK(s) > Build APK(s)) // actual on 01.04.2020
• rename APK file, replacing extension "apk" with extension "zip"
• unpack zip file to a new folder
• go to libs folder
• find out which *.jar libraries with incompatible ABIs are there

You may try to upgrade version / remove / replace these libraries to solve INSTALL_FAILED_NO_MATCHING_ABIS when install apk problem

The globals() function returns a dictionary, where keys are names of objects you can name (and values, by the way, are ids of these objects) The exec() function takes a string and executes it as if you just type it in a python console. So, the code is

for i in list(globals().keys()):
    if(i[0] != '_'):
        exec('del {}'.format(i))

To me, it seems as if your actual intention is to put different words on different lines. But let me answer your first question:

JLabel lab=new JLabel("text");
lab.setHorizontalAlignment(SwingConstants.LEFT);     

And if you have an image:

JLabel lab=new Jlabel("text");
lab.setIcon(new ImageIcon("path//img.png"));
lab.setHorizontalTextPosition(SwingConstants.LEFT);

But, I believe you want to make the label such that there are only 2 words on 1 line.

In that case try this:

String urText="<html>You can<br>use basic HTML<br>in Swing<br> components," 
   +"Hope<br> I helped!";
JLabel lac=new JLabel(urText);
lac.setAlignmentX(Component.RIGHT_ALIGNMENT);

Try this

function add_post($post_data){
   $this->db->insert('posts', $post_data);
   $insert_id = $this->db->insert_id();

   return  $insert_id;
}

In case of multiple inserts you could use

$this->db->trans_start();
$this->db->trans_complete();

Never is a good practice to pass the password argument directly from the command line, it is saved in the ~/.bash_history file and can be accessible from other applications.

Use this instead:

mysql -u user --host host --port 9999 database_name < /scripts/script.sql -p
Enter password:

I ran into similar problem - Invalid value encountered in ... After spending a lot of time trying to figure out what is causing this error I believe in my case it was due to NaN in my dataframe. Check out working with missing data in pandas.

None == None True

np.nan == np.nan False

When NaN is not equal to NaN then arithmetic operations like division and multiplication causes it throw this error.

Couple of things you can do to avoid this problem:

1. Use pd.set_option to set number of decimal to consider in your analysis so an infinitesmall number does not trigger similar problem - ('display.float_format', lambda x: '%.3f' % x).

2. Use df.round() to round the numbers so Panda drops the remaining digits from analysis. And most importantly,

3. Set NaN to zero df=df.fillna(0). Be careful if Filling NaN with zero does not apply to your data sets because this will treat the record as zero so N in the mean, std etc also changes.

After a bit of investigation, turns out that Safari on iOS6 will cache POSTs that have either no Cache-Control headers or even "Cache-Control: max-age=0".

The only way I've found of preventing this caching from happening at a global level rather than having to hack random querystrings onto the end of service calls is to set "Cache-Control: no-cache".

So:

• No Cache-Control or Expires headers = iOS6 Safari will cache
• Cache-Control max-age=0 and an immediate Expires = iOS6 Safari will cache
• Cache-Control: no-cache = iOS6 Safari will NOT cache

I suspect that Apple is taking advantage of this from the HTTP spec in section 9.5 about POST:

Responses to this method are not cacheable, unless the response includes appropriate Cache-Control or Expires header fields. However, the 303 (See Other) response can be used to direct the user agent to retrieve a cacheable resource.

So in theory you can cache POST responses...who knew. But no other browser maker has ever thought it would be a good idea until now. But that does NOT account for the caching when no Cache-Control or Expires headers are set, only when there are some set. So it must be a bug.

Below is what I use in the right bit of my Apache config to target the whole of my API because as it happens I don't actually want to cache anything, even gets. What I don't know is how to set this just for POSTs.

Header set Cache-Control "no-cache"

Update: Just noticed that I didn't point out that it is only when the POST is the same, so change any of the POST data or URL and you're fine. So you can as mentioned elsewhere just add some random data to the URL or a bit of POST data.

Update: You can limit the "no-cache" just to POSTs if you wish like this in Apache:

SetEnvIf Request_Method "POST" IS_POST
Header set Cache-Control "no-cache" env=IS_POST

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

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

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

t.start(); // Kick off calculations

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

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

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

Your runnable's run would look something like this:

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

Update based on Dmitri's answer

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

Use the MV* Pattern

Based on the example you attached, It's better in angular to use the following tools:

• ng-click - evaluates the expression when the element is clicked (Read More)
• ng-class - place a class based on the a given boolean expression (Read More)

for example:

<button ng-click="enabled=true">Click Me!</button>

<div ng-class="{'alpha':enabled}"> 
    ...
</div>

This gives you an easy way to decouple your implementation. e.g. you don't have any dependency between the div and the button.

Read this to learn about the MV* Pattern

exit 1 is all you need. The 1 is a return code, so you can change it if you want, say, 1 to mean a successful run and -1 to mean a failure or something like that.

Like docs say:

When the command line does not specify where to push with the <repository> argument, branch.*.remote configuration for the current branch is consulted to determine where to push. If the configuration is missing, it defaults to origin.

This can happen if any part of your highlighted method or property is attempting to access a property or method with the incorrect type.

Here is a troubleshooting checklist:

• Make sure the type of arguments match in the call site and implementation.
• Make sure the argument names match in the call site and implementation.
• Make sure the method name matches in the call site and implementation.
• Make sure the returned value of a property or method matches in the usage and implementation (ie: enumerated())
• Make sure you don't have a duplicated method with potentially ambiguous types such as with protocols or generics.
• Make sure the compiler can infer the correct type when using type inference.

A Strategy

• Try breaking apart your method into a greater number of simpler method/implementations.

For example, lets say you are running compactMap on an array of custom Types. In the closure you are passing to the compactMap method, you initialize and return another custom struct. When you get this error, it is difficult to tell which part of your code is offending.

• For debugging purposes, you can use a for loop instead of compactMap.
• instead of passing the arguments, directly, you can assign them to constants in the for loop.

By this point, you may come to a realization, such as, instead of the property you thought you wanted to assign actually had a property on it that had the actual value you wanted to pass.

A character frequency count is a common task for some applications (such as education) but not general enough to warrant inclusion with the core Java APIs. As such, you'll probably need to write your own function.

Try

<html style="width:100%; height:100%; margin: 0; padding: 0;">
<body style="overflow:hidden; width:100%; height:100%; margin:0; padding:0;">

Lots of ways.

Use ADO.Net and use fill on the data adapter to get a DataTable:

using (SqlDataAdapter dataAdapter
    = new SqlDataAdapter ("SELECT blah FROM blahblah ", sqlConn))
{
    // create the DataSet 
    DataSet dataSet = new DataSet(); 
    // fill the DataSet using our DataAdapter 
    dataAdapter.Fill (dataSet);
}

You can then get the data table out of the dataset.

Note in the upvoted answer dataset isn't used, (It appeared after my answer) It does

// create data adapter
SqlDataAdapter da = new SqlDataAdapter(cmd);
// this will query your database and return the result to your datatable
da.Fill(dataTable);

Which is preferable to mine.

I would strongly recommend looking at entity framework though ... using datatables and datasets isn't a great idea. There is no type safety on them which means debugging can only be done at run time. With strongly typed collections (that you can get from using LINQ2SQL or entity framework) your life will be a lot easier.

Edit: Perhaps I wasn't clear: Datatables = good, datasets = evil. If you are using ADO.Net then you can use both of these technologies (EF, linq2sql, dapper, nhibernate, orm of the month) as they generally sit on top of ado.net. The advantage you get is that you can update your model far easier as your schema changes provided you have the right level of abstraction by levering code generation.

The ado.net adapter uses providers that expose the type info of the database, for instance by default it uses a sql server provider, you can also plug in - for instance - devart postgress provider and still get access to the type info which will then allow you to as above use your orm of choice (almost painlessly - there are a few quirks) - i believe Microsoft also provide an oracle provider. The ENTIRE purpose of this is to abstract away from the database implementation where possible.

Well there's always

assertThat(list.isEmpty(), is(false));

... but I'm guessing that's not quite what you meant :)

Alternatively:

assertThat((Collection)list, is(not(empty())));

empty() is a static in the Matchers class. Note the need to cast the list to Collection, thanks to Hamcrest 1.2's wonky generics.

The following imports can be used with hamcrest 1.3

import static org.hamcrest.Matchers.empty;

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

In addition to Varun Achar's answer, this is the Java 8 variant I came up with, that uses java.time.LocalDate and ZonedDateTime instead of the old java.util.Date classes.

public class LocalDateDeserializer extends JsonDeserializer<LocalDate> {

    @Override
    public LocalDate deserialize(JsonParser jsonparser, DeserializationContext deserializationcontext) throws IOException {

        String string = jsonparser.getText();

        if(string.length() > 20) {
            ZonedDateTime zonedDateTime = ZonedDateTime.parse(string);
            return zonedDateTime.toLocalDate();
        }

        return LocalDate.parse(string);
    }
  }

I know this is old but just wanted to mention that I tried this with PHP 7.2:

<?php
//Creating array with 1 000 000 elements
$a = array();
for ($i = 0; $i < 1000000; ++$i)
{
    $a[] = 100;
}

//Measure
$time = time();
for ($i = 0; $i < 1000000000; ++$i)
{
    $b = count($a);
}
print("1 000 000 000 iteration of count() took ".(time()-$time)." sec\n");

$time = time();
for ($i = 0; $i < 1000000000; ++$i)
{
    $b = sizeof($a);
}
print("1 000 000 000 iteration of sizeof() took ".(time()-$time)." sec\n");
?>

and the result was:

1 000 000 000 iteration of count() took 414 sec
1 000 000 000 iteration of sizeof() took 1369 sec

So just use count().

I got the same problem with @ManyToOne column. It was solved... in stupid way. I had all other annotations for public getter methods, because they were overridden from parent class. But last field was annotated for private variable like in all other classes in my project. So I got the same MappingException without the reason.

Solution: I placed all annotations at public getter methods. I suppose, Hibernate can't handle cases, when annotations for private fields and public getters are mixed in one class.

Cool U guys, I just found this:

http://ptomato.wordpress.com/2012/02/09/geek-tip-running-python-guis-in-sublime-text-2/

It explains (like one of the answers above) how to edit this exec.py in the default directory.

I had the problem that my PYTHON UI APPLICATION would not start. I commented out the last line from the following snipped:

    # Hide the console window on Windows
    startupinfo = None
    if os.name == "nt":
        startupinfo = subprocess.STARTUPINFO()

We put together Web Services on Windows Server and were trying to connect with PHP on Apache. We got the same error. The issue ended up being different versions of the Soap client on the different servers. Matching the SOAP versions in the options on both servers solved the issue in our case.

You may want to try this.

You could try to reinstall the ca-certificates package, or explicitly allow the certificate in question as described here.

This functionality is not built-in to C# 5 or below.
Update: C# 6 now supports string interpolation, see newer answers.

The recommended way to do this would be with String.Format:

string name = "Scott";
string output = String.Format("Hello {0}", name);

However, I wrote a small open-source library called SmartFormat that extends String.Format so that it can use named placeholders (via reflection). So, you could do:

string name = "Scott";
string output = Smart.Format("Hello {name}", new{name}); // Results in "Hello Scott".

Hope you like it!

What is the difference between logger.debug and logger.info?

These are only some default level already defined. You can define your own levels if you like. The purpose of those levels is to enable/disable one or more of them, without making any change in your code.

When logger.debug will be printed ??

When you have enabled the debug or any higher level in your configuration.

My idea is let two JavaScript call function through DOM.

The way to do it is simple ... We just need to define hidden js_ipc html tag. After the callee register click from the hidden js_ipc tag, then The caller can dispatch the click event to trigger callee. And the argument is save in the event that you want to pass.

When we need to use above way ?

Sometime, the two javascript code is very complicated to integrate and so many async code there. And different code use different framework but you still need to have a simple way to integrate them together.

So, in that case, it is not easy to do it.

In my project's implementation, I meet this case and it is very complicated to integrate. And finally I found out that we can let two javascript call each other through DOM.

I demonstrate this way in this git code. you can get it through this way. (Or read it from https://github.com/milochen0418/javascript-ipc-demo)

git clone https://github.com/milochen0418/javascript-ipc-demo
cd javascript-ipc-demo
git checkout 5f75d44530b4145ca2b06105c6aac28b764f066e

Anywhere, Here, I try to explain by the following simple case. I hope that this way can help you to integrate two different javascript code easier than before there is no any JavaScript library to support communication between two javascript file that made by different team.

You need a server-side support to achieve this. Basically your form should be posted (AJAX is fine as well) to the server and that server should connect via SMTP to some mail provider and send that e-mail.

Even if it was possible to send e-mails directly using JavaScript (that is from users computer), the user would still have to connect to some SMTP server (like gmail.com), provide SMTP credentials, etc. This is normally handled on the server-side (in your application), which knows these credentials.

instead of click on Restore Database click on Restore File and Filegroups..

thats work on my sql server

$(document).keydown(function(e){
    if (e.which == 37) { 
       alert("left pressed");
       return false;
    }
});

Character codes:

37 - left

38 - up

39 - right

40 - down

Use this

long startTime = System.currentTimeMillis();
long elapsedTime = 0L.

while (elapsedTime < 2*60*1000) {
    //perform db poll/check
    elapsedTime = (new Date()).getTime() - startTime;
}

//Throw your exception

I have got the same issue, here I give my problem and my solution hoping this would help someone:

Following other people recommendation I went to the log of the server (Windows Server 2012 in my case) in :

Control Panel -> Administrative Tools -> Event Viewer

Then in the left side:

Windows Logs -> Application:

In the warnings I found the message from my site and in my case it was due to a null reference:

*Exception type: NullReferenceException 
Exception message: Object reference not set to an instance of an object.*

And checking at the function described in the log I found a non initialized object and that was it.

So it could be a null reference exception in the code. Hope someone find this useful, greetings.

When you are using Multiple css property with jQuery then you must use the curly Brace in starting and in the end. You are missing the ending curly brace.

function init() {
 $("h1").css("backgroundColor", "yellow");

 $("#myParagraph").css({"background-color":"black","color":"white"});

 $(".bordered").css("border", "1px solid black");
}

You can have a look at this jQuery CSS Selector tutorial.

So Why not use powershell to create the list of source files for you. Take a look at this script

param (
    [Parameter(Mandatory=$True)]
    [string]$root 
)

if (-not (Test-Path  -Path $root)) {    
throw "Error directory does not exist"
}

#get the full path of the root
$rootDir = get-item -Path $root
$fp=$rootDir.FullName;


$files = Get-ChildItem -Path $root -Recurse -File | 
         Where-Object { ".cpp",".cxx",".cc",".h" -contains $_.Extension} | 
         Foreach {$_.FullName.replace("${fp}\","").replace("\","/")}

$CMakeExpr = "set(SOURCES "

foreach($file in $files){

    $CMakeExpr+= """$file"" " ;
}
$CMakeExpr+=")"
return $CMakeExpr;

Suppose you have a folder with this structure

C:\Workspace\A
--a.cpp
C:\Workspace\B 
--b.cpp

Now save this file as "generateSourceList.ps1" for example, and run the script as

~>./generateSourceList.ps1 -root "C:\Workspace" > out.txt

out.txt file will contain

set(SOURCE "A/a.cpp" "B/b.cpp")

Test this

  var selected = this.ComboBox.GetItemText(this.ComboBox.SelectedItem);
  MessageBox.Show(selected);

This is what we use in ASP.NET:

// Stop Caching in IE
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache);

// Stop Caching in Firefox
Response.Cache.SetNoStore();

It stops caching in Firefox and IE, but we haven't tried other browsers. The following response headers are added by these statements:

Cache-Control: no-cache, no-store
Pragma: no-cache

This will show image of base 64 data:

<style>
.logo {
      width: 290px;
      height: 63px;
      background: url(data:image/png;base64,copy-paste-base64-data-here) no-repeat;
}
</style>

<div class="logo"></div>

I had the same problem to show an user detail from my application.

You can do this:

<Link to={'/ideas/'+this.props.testvalue }>Create Idea</Link>

or

<Link to="ideas/hello">Create Idea</Link>

and

<Route name="ideas/:value" handler={CreateIdeaView} />

to get this via this.props.match.params.value at your CreateIdeaView class.

You can see this video that helped me a lot: https://www.youtube.com/watch?v=ZBxMljq9GSE

If someone is looking for analogy , this answer might be helpful.

WSDL is like 'SHOW TABLE STATUS' command in mysql. It defines all the elements(request type, response type, format of URL to hit request,etc.,) which should be part of XML. By definition I mean: 1) Names of request or response 2) What should be treated as input , what should be treated as output.

XSD is like DESCRIBE command in mysql. It tells what all variables and their types, a request and response contains.

It's a long pointer to a constant, wide string (i.e. a string of wide characters).

Since it's a wide string, you want to make your constant look like: L"TestWindow". I wouldn't create the intermediate a either, I'd just pass L"TestWindow" for the parameter:

ghTest = FindWindowEx(NULL, NULL, NULL, L"TestWindow");

If you want to be pedantically correct, an "LPCTSTR" is a "text" string -- a wide string in a Unicode build and a narrow string in an ANSI build, so you should use the appropriate macro:

ghTest = FindWindow(NULL, NULL, NULL, _T("TestWindow"));

Few people care about producing code that can compile for both Unicode and ANSI character sets though, and if you don't getting it to really work correctly can be quite a bit of extra work for little gain. In this particular case, there's not much extra work, but if you're manipulating strings, there's a whole set of string manipulation macros that resolve to the correct functions.

On python 3.5+ there is an easier way to achieve a shallow copy by using the ** unpackaging operator. Defined by Pep 448.

>>>dict1 = {"key1": "value1", "key2": "value2"}
>>>dict2 = {**dict1}
>>>print(dict2)
{'key1': 'value1', 'key2': 'value2'}
>>>dict2["key2"] = "WHY?!"
>>>print(dict1)
{'key1': 'value1', 'key2': 'value2'}
>>>print(dict2)
{'key1': 'value1', 'key2': 'WHY?!'}

** unpackages the dictionary into a new dictionary that is then assigned to dict2.

We can also confirm that each dictionary has a distinct id.

>>>id(dict1)
 178192816

>>>id(dict2)
 178192600

If a deep copy is needed then copy.deepcopy() is still the way to go.

This only inserts if the item to be inserted is not already present.

Works the same as:

if not exists (...) insert ... 

in T-SQL

insert into destination (DESTINATIONABBREV) 
  select 'xyz' from dual 
  left outer join destination d on d.destinationabbrev = 'xyz' 
  where d.destinationid is null;

may not be pretty, but it's handy :)

I was just looking for a smiliar issue and I found this:

.div{
  height : 100vh;
}

more info

vw: 1/100th viewport width
vh: 1/100th viewport height
vmin: 1/100th of the smallest side
vmax: 1/100th of the largest side

This example works perfectly in Android

In kotlin you can use a lambda expression for this. The Kotlin Array Constructor definition is:

Array(size: Int, init: (Int) -> T)

Which evaluates to:

skillsSummaryDetailLinesArray = Array(linesLen) {
        i: Int -> skillsSummaryDetailLines!!.getString(i)
}

Or:

skillsSummaryDetailLinesArray = Array<String>(linesLen) {
        i: Int -> skillsSummaryDetailLines!!.getString(i)
}

In this example the field definition was:

private var skillsSummaryDetailLinesArray: Array<String>? = null

Hope this helps

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

I would prefer user defined data type : it is super fast.

Step 1 : Create User Defined Table in Sql Server DB

CREATE TYPE [dbo].[udtProduct] AS TABLE(
  [ProductID] [int] NULL,
  [ProductName] [varchar](50) NULL,
  [ProductCode] [varchar](10) NULL
)
GO

Step 2 : Create Stored Procedure with User Defined Type

CREATE PROCEDURE ProductBulkInsertion 
@product udtProduct readonly
AS
BEGIN
    INSERT INTO Product
    (ProductID,ProductName,ProductCode)
    SELECT ProductID,ProductName,ProductCode
    FROM @product
END

Step 3 : Execute Stored Procedure from c#

SqlCommand sqlcmd = new SqlCommand("ProductBulkInsertion", sqlcon);
sqlcmd.CommandType = CommandType.StoredProcedure;
sqlcmd.Parameters.AddWithValue("@product", productTable);
sqlcmd.ExecuteNonQuery();

Possible Issue : Alter User Defined Table

Actually there is no sql server command to alter user defined type But in management studio you can achieve this from following steps

1.generate script for the type.(in new query window or as a file) 2.delete user defied table. 3.modify the create script and then execute.

Within the class you can call function by using :

 $this->filter();

Outside of the class

you have to create an object of a class

 ex: $obj = new Functions();

     $obj->filter($param);    

for more about OOPs in php

this example:

class test {
 public function newTest(){
      $this->bigTest();// we don't need to create an object we can call simply using $this
      $this->smallTest();
 }

 private function bigTest(){
      //Big Test Here
 }

 private function smallTest(){
      //Small Test Here
 }

 public function scoreTest(){
      //Scoring code here;
 }
}

$testObject = new test();

$testObject->newTest();

$testObject->scoreTest();

hope it will help!

To know the difference you have to understand the box model, but basically:

clientHeight:

returns the inner height of an element in pixels, including padding but not the horizontal scrollbar height, border, or margin

offsetHeight:

is a measurement which includes the element borders, the element vertical padding, the element horizontal scrollbar (if present, if rendered) and the element CSS height.

scrollHeight:

is a measurement of the height of an element's content including content not visible on the screen due to overflow

I will make it easier:

Consider:

<element>                                     
    <!-- *content*: child nodes: -->        | content
    A child node as text node               | of
    <div id="another_child_node"></div>     | the
    ... and I am the 4th child node         | element
</element>                                    

scrollHeight: ENTIRE content & padding (visible or not)
_{Height of all content + paddings, despite of height of the element.}

clientHeight: VISIBLE content & padding
_{Only visible height: content portion limited by explicitly defined height of the element.}

offsetHeight: VISIBLE content & padding + border + scrollbar
_{Height occupied by the element on document.}

Unlikely.

Evaluate it in a try..catch or whatever your language provides.

The c# function, as expressed by Kyle Rozendo:

string DecimalPlaceNoRounding(double d, int decimalPlaces = 2)
{
    d = d * Math.Pow(10, decimalPlaces);
    d = Math.Truncate(d);
    d = d / Math.Pow(10, decimalPlaces);
    return string.Format("{0:N" + Math.Abs(decimalPlaces) + "}", d);
}

What happens if I promote the column to be a/the PK, too (a.k.a. identifying relationship)? As the column is now the PK, I must tag it with @Id (...).

This enhanced support of derived identifiers is actually part of the new stuff in JPA 2.0 (see the section 2.4.1 Primary Keys Corresponding to Derived Identities in the JPA 2.0 specification), JPA 1.0 doesn't allow Id on a OneToOne or ManyToOne. With JPA 1.0, you'd have to use PrimaryKeyJoinColumn and also define a Basic Id mapping for the foreign key column.

Now the question is: are @Id + @JoinColumn the same as just @PrimaryKeyJoinColumn?

You can obtain a similar result but using an Id on OneToOne or ManyToOne is much simpler and is the preferred way to map derived identifiers with JPA 2.0. PrimaryKeyJoinColumn might still be used in a JOINED inheritance strategy. Below the relevant section from the JPA 2.0 specification:

11.1.40 PrimaryKeyJoinColumn Annotation

The PrimaryKeyJoinColumn annotation specifies a primary key column that is used as a foreign key to join to another table.

The PrimaryKeyJoinColumn annotation is used to join the primary table of an entity subclass in the JOINED mapping strategy to the primary table of its superclass; it is used within a SecondaryTable annotation to join a secondary table to a primary table; and it may be used in a OneToOne mapping in which the primary key of the referencing entity is used as a foreign key to the referenced entity^[108].

...

If no PrimaryKeyJoinColumn annotation is specified for a subclass in the JOINED mapping strategy, the foreign key columns are assumed to have the same names as the primary key columns of the primary table of the superclass.

...

Example: Customer and ValuedCustomer subclass

@Entity
@Table(name="CUST")
@Inheritance(strategy=JOINED)
@DiscriminatorValue("CUST")
public class Customer { ... }

@Entity
@Table(name="VCUST")
@DiscriminatorValue("VCUST")
@PrimaryKeyJoinColumn(name="CUST_ID")
public class ValuedCustomer extends Customer { ... }

_{[108] The derived id mechanisms described in section 2.4.1.1 are now to be preferred over PrimaryKeyJoinColumn for the OneToOne mapping case.}

This source http://weblogs.java.net/blog/felipegaucho/archive/2009/10/24/jpa-join-table-additional-state states that using @ManyToOne and @Id works with JPA 1.x. Who's correct now?

The author is using a pre release JPA 2.0 compliant version of EclipseLink (version 2.0.0-M7 at the time of the article) to write an article about JPA 1.0(!). This article is misleading, the author is using something that is NOT part of JPA 1.0.

For the record, support of Id on OneToOne and ManyToOne has been added in EclipseLink 1.1 (see this message from James Sutherland, EclipseLink comitter and main contributor of the Java Persistence wiki book). But let me insist, this is NOT part of JPA 1.0.

You don't need root to pull the apk files from /data/app. Sure, you might not have permissions to list the contents of that directory, but you can find the file locations of APKs with:

adb shell pm list packages -f

Then you can use adb pull:

adb pull <APK path from previous command>

and then aapt to get the information you want:

aapt dump badging <pulledfile.apk>

The accepted answer detects digits but does not detect formated numbers, e.g. 2,000, nor decimals, e.g. 4.8. For such use -?\\d+(,\\d+)*?\\.?\\d+?:

Pattern p = Pattern.compile("-?\\d+(,\\d+)*?\\.?\\d+?");
List<String> numbers = new ArrayList<String>();
Matcher m = p.matcher("Government has distributed 4.8 million textbooks to 2,000 schools");
while (m.find()) {  
    numbers.add(m.group());
}   
System.out.println(numbers);

Output: [4.8, 2,000]

All objects in python are implemented via references so the distinction between objects and pointers to objects does not exist in source code.

The python equivalent of NULL is called None (good info here). As all objects in python are implemented via references, you can re-write your struct to look like this:

class Node:
    def __init__(self): #object initializer to set attributes (fields)
        self.val = 0
        self.right = None
        self.left = None

And then it works pretty much like you would expect:

node = Node()
node.val = some_val #always use . as everything is a reference and -> is not used
node.left = Node()

Note that unlike in NULL in C, None is not a "pointer to nowhere": it is actually the only instance of class NoneType. Therefore, as None is a regular object, you can test for it just like any other object:

if node.left == None:
   print("The left node is None/Null.")

Although since None is a singleton instance, it is considered more idiomatic to use is and compare for reference equality:

if node.left is None:
   print("The left node is None/Null.")

A warning about the Jquery Caret plugin.

It will conflict with the Masked Input plugin (or vice versa). Fortunately the Masked Input plugin includes a caret() function of its own, which you can use very similarly to the Caret plugin for your basic needs - $(element).caret().begin or .end

You could declare your functions outside of the module.exports block.

var foo = function (req, res, next) {
  return ('foo');
}

var bar = function (req, res, next) {
  return foo();
}

Then:

module.exports = {
  foo: foo,
  bar: bar
}

If you have declare a bitmap object and you want to display it or store this bitmap object. but first you have to assign any image , and you may use the button click event, this code will only demonstrate that how to store the drawable image in bitmap Object.

Bitmap contact_pic = BitmapFactory.decodeResource(
                           v.getContext().getResources(),
                           R.drawable.android_logo
                     );

Now you can use this bitmap object, whether you want to store it, or to use it in google maps while drawing a pic on fixed latitude and longitude, or to use some where else

I test with below code and it is fine.

The easiest solution in C# for inter-process communication when security is not a concern and given your constraints (two C# processes on the same machine) is the Remoting API. Now Remoting is a legacy technology (not the same as deprecated) and not encouraged for use in new projects, but it does work well and does not require a lot of pomp and circumstance to get working.

There is an excellent article on MSDN for using the class IpcChannel from the Remoting framework (credit to Greg Beech for the find here) for setting up a simple remoting server and client.

I Would suggest trying this approach first, and then try to port your code to WCF (Windows Communication Framework). Which has several advantages (better security, cross-platform), but is necessarily more complex. Luckily MSDN has a very good article for porting code from Remoting to WCF.

If you want to dive in right away with WCF there is a great tutorial here.

Thanks guys for help. From your suggestions i reached a solution like this.

If you are dead-set on doing this yourself then you could add shapes to the worksheet and use VBA to hide and unhide rows and columns on clicking the shapes.

• Ensure debug mode is on - either add APP_DEBUG=true to .env file or set an environment variable

• Log files are in storage/logs folder. laravel.log is the default filename. If there is a permission issue with the log folder, Laravel just halts. So if your endpoint generally works - permissions are not an issue.

• In case your calls don't even reach Laravel or aren't caused by code issues - check web server's log files (check your Apache/nginx config files to see the paths).

• If you use PHP-FPM, check its log files as well (you can see the path to log file in PHP-FPM pool config).

Worked for me using the parameter --user-install running following command:

gem install name_of_gem --user-install

Then he started to fetch and install it.

Edit

There was one gem I still could not install (it required the Ruby.h headers of the Ruby development kit or something), then I tried the different version managers, but somehow that still did not really work as it was stated in the documentations how to just install and switch (it did just not switch the versions). Then I removed all the installed version managers and installed afterwards with brew install ruby the latest version and did set the PATH variable, too. (It will be mentioned after the installation of ruby from brew), which worked.

Try adding the css style property

position:relative;

to the div tag , it works ,

Set oShell = CreateObject ("WScript.Shell") 
oShell.run "cmd.exe /C copy ""S:Claims\Sound.wav"" ""C:\WINDOWS\Media\Sound.wav"" "

I usually use JSON for more complicated data structures. The downside is that you easily end up with a bunch of code to tell the user where the error was, various edge cases and what not.

For base configuration (api keys, port numbers, ...) I've had very good luck with the gcfg package. It is based on the git config format.

From the documentation:

Sample config:

; Comment line
[section]
name = value # Another comment
flag # implicit value for bool is true

Go struct:

type Config struct {
    Section struct {
            Name string
            Flag bool
    }
}

And the code needed to read it:

var cfg Config
err := gcfg.ReadFileInto(&cfg, "myconfig.gcfg")

It also supports slice values, so you can allow specifying a key multiple times and other nice features like that.

If you just want the last date for each account, you'd use this:

var q = from n in table
        group n by n.AccountId into g
        select new {AccountId = g.Key, Date = g.Max(t=>t.Date)};

If you want the whole record:

var q = from n in table
        group n by n.AccountId into g
        select g.OrderByDescending(t=>t.Date).FirstOrDefault();

You can try webshims, which is available on cdn + only loads the polyfill, if it is needed.

Here is a demo with CDN: http://jsfiddle.net/trixta/BMEc9/

<!-- cdn for modernizr, if you haven't included it already -->
<script src="http://cdn.jsdelivr.net/webshim/1.12.4/extras/modernizr-custom.js"></script>
<!-- polyfiller file to detect and load polyfills -->
<script src="http://cdn.jsdelivr.net/webshim/1.12.4/polyfiller.js"></script>
<script>
  webshims.setOptions('waitReady', false);
  webshims.setOptions('forms-ext', {types: 'date'});
  webshims.polyfill('forms forms-ext');
</script>

<input type="date" />

In case the default configuration does not satisfy, there are many ways to configure it. Here you find the datepicker configurator.

Note: While there might be new bugfix releases for webshim in the future. There won't be any major releases anymore. This includes support for jQuery 3.0 or any new features.

I think that the code you are looking for is:

Array.Copy(oldArray, 0, newArray, BeginIndex, EndIndex - BeginIndex)

You are mixing razor and aspx syntax,if your view engine is razor just do this:

<button class="btn btn-info" type="button" id="addressSearch"   
          onclick="location.href='@Url.Action("List", "Search")'">

The fix for me was to set property HorizontalAlignment="Stretch" on ItemsPresenter inside ScrollViewer..

Hope this helps someone...

<Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListBox">
                    <ScrollViewer x:Name="ScrollViewer" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Foreground="{TemplateBinding Foreground}" Padding="{TemplateBinding Padding}" HorizontalAlignment="Stretch">
                        <ItemsPresenter  Height="252" HorizontalAlignment="Stretch"/>
                    </ScrollViewer>
                </ControlTemplate>
            </Setter.Value>
        </Setter>

From Primitives Data Types:

• float: The float data type is a single-precision 32-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in section 4.2.3 of the Java Language Specification. As with the recommendations for byte and short, use a float (instead of double) if you need to save memory in large arrays of floating point numbers. This data type should never be used for precise values, such as currency. For that, you will need to use the java.math.BigDecimal class instead. Numbers and Strings covers BigDecimal and other useful classes provided by the Java platform.

• double: The double data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in section 4.2.3 of the Java Language Specification. For decimal values, this data type is generally the default choice. As mentioned above, this data type should never be used for precise values, such as currency.

For the range of values, see the section 4.2.3 Floating-Point Types, Formats, and Values of the JLS.

If you have the file descriptor fstat() returns a stat structure which contain the file size.

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

// fd = fileno(f); //if you have a stream (e.g. from fopen), not a file descriptor.
struct stat buf;
fstat(fd, &buf);
off_t size = buf.st_size;

Checkout __FILE__ and __LINE__ macros

1. run command in terminal nano $HOME/.zshrc

2. Must include next lines:

   export PATH=$PATH:~/Library/Android/sdk/platform-tools
   export ANDROID_HOME=~/Library/Android/sdk
   export PATH="$HOME/.bin:$PATH"
   export PATH="~/Library/Android/sdk/platform-tools":$PATH
   

3. Press Command + X to save file in editor,Enter Yes or No and hit Enter key

4. Run source ~/.zshrc

5. Check adb in terminal, run adb

Am not sure if there is any difference am using code igniter and i use "" for the names and it works great.

$department = mysql_real_escape_string($_POST["department"]);
$name = mysql_real_escape_string($_POST["name"]);
$email = mysql_real_escape_string($_POST["email"]);
$message = mysql_real_escape_string($_POST["message"]);

The example below includes scrolling behaviour if the content of the expanded centre component extends past its bounds. Also the centre component takes 100% of remaining space in the viewport.

jsfiddle here

html, body, .r_flex_container{
    height: 100%;
    display: flex;
    flex-direction: column;
    background: red;
    margin: 0;
}
.r_flex_container {
    display:flex;
    flex-flow: column nowrap;
    background-color:blue;
}

.r_flex_fixed_child {
    flex:none;
    background-color:black;
    color:white;

}
.r_flex_expand_child {
    flex:auto;
    background-color:yellow;
    overflow-y:scroll;
}

Example of html that can be used to demonstrate this behaviour

<html>
<body>
    <div class="r_flex_container">
      <div class="r_flex_fixed_child">
        <p> This is the fixed 'header' child of the flex container </p>
      </div>
      <div class="r_flex_expand_child">
            <article>this child container expands to use all of the space given to it -  but could be shared with other expanding childs in which case they would get equal space after the fixed container space is allocated.

EDIT Fixed the syntax...

Also, have a look at the following example

SQLFiddle DEMO

For the record, the spring.jpa.hibernate.ddl-auto property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto.

The values create, create-drop, validate, and update basically influence how the schema tool management will manipulate the database schema at startup.

For example, the update operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.

The update operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.

Typically in test case scenarios, you'll likely use create-drop so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.

In development, it's often common to see developers use update to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.

In production, it's often highly recommended you use none or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.

The answer should be Jain. You can not select an element via pseudo-selector, but you can add a new rule to your stylesheet with insertRule.

I made something that should work for you:

var addRule = function(sheet, selector, styles) {
    if (sheet.insertRule) return sheet.insertRule(selector + " {" + styles + "}", sheet.cssRules.length);
    if (sheet.addRule) return sheet.addRule(selector, styles);
};

addRule(document.styleSheets[0], "body:before", "content: 'foo'");

http://fiddle.jshell.net/MDyxg/1/

To be super-cool (and to answer the question really) I rolled it out again and wrapped this in a jQuery-plugin (however, jquery is still not required!):

/*!
 * jquery.addrule.js 0.0.1 - https://gist.github.com/yckart/5563717/

(function ($) {

    window.addRule = function (selector, styles, sheet) {

        styles = (function (styles) {
            if (typeof styles === "string") return styles;
            var clone = "";
            for (var p in styles) {
                if (styles.hasOwnProperty(p)) {
                    var val = styles[p];
                    p = p.replace(/([A-Z])/g, "-$1").toLowerCase(); // convert to dash-case
                    clone += p + ":" + (p === "content" ? '"' + val + '"' : val) + "; ";
                }
            }
            return clone;
        }(styles));
        sheet = sheet || document.styleSheets[document.styleSheets.length - 1];

        if (sheet.insertRule) sheet.insertRule(selector + " {" + styles + "}", sheet.cssRules.length);
        else if (sheet.addRule) sheet.addRule(selector, styles);

        return this;

    };

    if ($) $.fn.addRule = function (styles, sheet) {
        addRule(this.selector, styles, sheet);
        return this;
    };

}(window.jQuery));

The usage is quite simple:

$("body:after").addRule({
    content: "foo",
    color: "red",
    fontSize: "32px"
});

// or without jquery
addRule("body:after", {
    content: "foo",
    color: "red",
    fontSize: "32px"
});

If you get to the point where all the mentioned solutions don't work (as it got for me), do this:

• Create two tables. One for the header and another for the body
• Give the two tables different parent containers/divs
• Style the second table's div to allow vertical scroll of its contents.

Like this, in your HTML

<div class="table-header-class">
    <table>
       <thead>
          <tr>
            <th>Ava</th>
            <th>Alexis</th>
            <th>Mcclure</th>
          </tr>
       </thead>
    </table>
</div>
<div class="table-content-class">
   <table>
       <tbody>
          <tr>
            <td>I am the boss</td>
            <td>No, da-da is not the boss!</td>
            <td>Alexis, I am the boss, right?</td>
          </tr>
       </tbody>
    </table>
</div>

Then style the second table's parent to allow vertical scroll, in your CSS

    .table-content-class {
        overflow-y: scroll;    // use auto; or scroll; to allow vertical scrolling; 
        overflow-x: hidden;    // disable horizontal scroll 
    }

I know you want to "alter a procedure if it exists and create it if it does not exist" but I believe it's simpler to just always drop the procedure and then re-create it. Here's how to drop the procedure only if it already exists:

IF OBJECT_ID('MyProcedure', 'P') IS NOT NULL
    DROP PROCEDURE MyProcedure
GO

The second parameter tells OBJECT_ID to only look for objects with object_type = 'P', which are stored procedures:

AF = Aggregate function (CLR)

C = CHECK constraint

D = DEFAULT (constraint or stand-alone)

F = FOREIGN KEY constraint

FN = SQL scalar function

FS = Assembly (CLR) scalar-function

FT = Assembly (CLR) table-valued function

IF = SQL inline table-valued function

IT = Internal table

P = SQL Stored Procedure

PC = Assembly (CLR) stored-procedure

PG = Plan guide

PK = PRIMARY KEY constraint

R = Rule (old-style, stand-alone)

RF = Replication-filter-procedure

S = System base table

SN = Synonym

SO = Sequence object

TF = SQL table-valued-function

TR = Trigger

You can get the full list of options via:

SELECT name 
FROM master..spt_values
WHERE type = 'O9T'

There does not seem to be a straight-forward way provided by Google or Yahoo finance portals to download the full list of tickers. One possible 'brute force' way to get it is to query their APIs for every possible combinations of letters and save only those that return valid results. As silly as it may seem there are people who actually do it (ie. check this: http://investexcel.net/all-yahoo-finance-stock-tickers/).

You can download lists of symbols from exchanges directly or 3rd party websites as suggested by @Eugene S and @Capn Sparrow, however if you intend to use it to fetch data from Google or Yahoo, you have to sometimes use prefixes or suffixes to make sure that you're getting the correct data. This is because some symbols may repeat between exchanges, so Google and Yahoo prepend or append exchange codes to the tickers in order to distinguish between them. Here's an example:

Company:  Vodafone
------------------
LSE symbol:    VOD
 in Google:    LON:VOD
 in Yahoo:     VOD.L
NASDAQ symbol: VOD
 in Google:    NASDAQ:VOD
 in Yahoo:     VOD

I use columnDefinition and it works very good

@Column(columnDefinition="TIMESTAMP DEFAULT CURRENT_TIMESTAMP")

private Date createdDate;

You can directly call the

pd.DataFrame()

method and pass your list as parameter.

l = ['Thanks You','Its fine no problem','Are you sure']
pd.DataFrame(l)

Output:

                      0
0            Thanks You
1   Its fine no problem
2          Are you sure

And if you have multiple lists and you want to make a dataframe out of it.You can do it as following:

import pandas as pd
names =["A","B","C","D"]
salary =[50000,90000,41000,62000]
age = [24,24,23,25]
data = pd.DataFrame([names,salary,age]) #Each list would be added as a row
data = data.transpose() #To Transpose and make each rows as columns
data.columns=['Names','Salary','Age'] #Rename the columns
data.head()

Output:

    Names   Salary  Age
0       A    50000   24
1       B    90000   24
2       C    41000   23
3       D    62000   25

Simple Override onBackPressed Method:

    @Override
    public void onBackPressed() {
            super.onBackPressed();
            this.finish();
    }

A single method is all you need for all your random enums:

    public static <T extends Enum<?>> T randomEnum(Class<T> clazz){
        int x = random.nextInt(clazz.getEnumConstants().length);
        return clazz.getEnumConstants()[x];
    }

Which you'll use:

randomEnum(MyEnum.class);

I also prefer to use SecureRandom as:

private static final SecureRandom random = new SecureRandom();

It was requested that I add this functionality to the stackoverflow R package. Given that it is a tinyverse package (and can't depend on third party packages), here is what I came up with:

#' Bulk import data files 
#' 
#' Read in each file at a path and then unnest them. Defaults to csv format.
#' 
#' @param path        a character vector of full path names
#' @param pattern     an optional \link[=regex]{regular expression}. Only file names which match the regular expression will be returned.
#' @param reader      a function that can read data from a file name.
#' @param ...         optional arguments to pass to the reader function (eg \code{stringsAsFactors}).
#' @param reducer     a function to unnest the individual data files. Use I to retain the nested structure. 
#' @param recursive     logical. Should the listing recurse into directories?
#'  
#' @author Neal Fultz
#' @references \url{https://stackoverflow.com/questions/11433432/how-to-import-multiple-csv-files-at-once}
#' 
#' @importFrom utils read.csv
#' @export
read.directory <- function(path='.', pattern=NULL, reader=read.csv, ..., 
                           reducer=function(dfs) do.call(rbind.data.frame, dfs), recursive=FALSE) {
  files <- list.files(path, pattern, full.names = TRUE, recursive = recursive)

  reducer(lapply(files, reader, ...))
}

By parameterizing the reader and reducer function, people can use data.table or dplyr if they so choose, or just use the base R functions that are fine for smaller data sets.

Let me explain a bit about the one case where you have to use final, which Jon already mentioned:

If you create an anonymous inner class in your method and use a local variable (such as a method parameter) inside that class, then the compiler forces you to make the parameter final:

public Iterator<Integer> createIntegerIterator(final int from, final int to)
{
    return new Iterator<Integer>(){
        int index = from;
        public Integer next()
        {
            return index++;
        }
        public boolean hasNext()
        {
            return index <= to;
        }
        // remove method omitted
    };
}

Here the from and to parameters need to be final so they can be used inside the anonymous class.

The reason for that requirement is this: Local variables live on the stack, therefore they exist only while the method is executed. However, the anonymous class instance is returned from the method, so it may live for much longer. You can't preserve the stack, because it is needed for subsequent method calls.

So what Java does instead is to put copies of those local variables as hidden instance variables into the anonymous class (you can see them if you examine the byte code). But if they were not final, one might expect the anonymous class and the method seeing changes the other one makes to the variable. In order to maintain the illusion that there is only one variable rather than two copies, it has to be final.

Fastest way for Android Studio 3.x.x and Android Studio 4.x.x

1.Go to the design tab of the activity layout

2.At the top you should press on the orientation for preview button, there is a option to create a landscape layout (check image), a new folder will be created as your xml layout file for that particular orientation

Here's the code that works for me everytime (for Outlook emails):

#to read Subjects and Body of email in a folder (or subfolder)

import win32com.client  
#import package

outlook = win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")  
#create object

#get to the desired folder ([email protected] is my root folder)

root_folder = 
outlook.Folders['[email protected]'].Folders['Inbox'].Folders['SubFolderName']

#('Inbox' and 'SubFolderName' are the subfolders)

messages = root_folder.Items

for message in messages:
if message.Unread == True:    # gets only 'Unread' emails
    subject_content = message.subject
# to store subject lines of mails

    body_content = message.body
# to store Body of mails

    print(subject_content)
    print(body_content)

    message.Unread = True         # mark the mail as 'Read'
    message = messages.GetNext()  #iterate over mails

See ?boxplot for all the help you need.

 outline: if ‘outline’ is not true, the outliers are not drawn (as
          points whereas S+ uses lines).

boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)

And for extending the range of the whiskers and suppressing the outliers inside this range:

   range: this determines how far the plot whiskers extend out from the
          box.  If ‘range’ is positive, the whiskers extend to the most
          extreme data point which is no more than ‘range’ times the
          interquartile range from the box. A value of zero causes the
          whiskers to extend to the data extremes.

# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)

By psql --help, when you didn't set options for database name (without -d option) it would be your username, if you didn't do -U, the database username would be your username too, etc.

But by initdb (to create the first database) command it doesn't have your username as any database name. It has a database named postgres. The first database is always created by the initdb command when the data storage area is initialized. This database is called postgres.

So if you don't have another database named your username, you need to do psql -d postgres for psql command to work. And it seems it gives -d option by default, psql postgres also works.

If you have created another database names the same to your username, (it should be done with createdb) then you may command psql only. And it seems the first database user name sets as your machine username by brew.

psql -d <first database name> -U <first database user name>

or,

psql -d postgres -U <your machine username>
psql -d postgres

would work by default.

jQuery provides a .text() method that can be used in any browser. For example:

$('#myElement').text("Foo");

Array functional way:

   array.enumerated().filter { $0.offset < limit }.map { $0.element }

ranged:

 array.enumerated().filter { $0.offset >= minLimit && $0.offset < maxLimit }.map { $0.element }

The advantage of this method is such implementation is safe.

EDIT: yes I agree this is not a correct MVVM approach and I am now using something similar to what is suggested by blindmeis.

One of the way you could to this is

In your Main View Model (where you open the modal):

void OpenModal()
{
    ModalWindowViewModel mwvm = new ModalWindowViewModel();
    Window mw = new Window();
    mw.content = mwvm;
    mw.ShowDialog()
    if(mw.DialogResult == true)
    { 
        // Your Code, you can access property in mwvm if you need.
    }
}

And in your Modal Window View/ViewModel:

XAML:

<Button Name="okButton" Command="{Binding OkCommand}" CommandParameter="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Window}}}">OK</Button>
<Button Margin="2" VerticalAlignment="Center" Name="cancelButton" IsCancel="True">Cancel</Button>

ViewModel:

public ICommand OkCommand
{
    get
    {
        if (_okCommand == null)
        {
            _okCommand = new ActionCommand<Window>(DoOk, CanDoOk);
        }
        return _okCommand ;
    }
}

void DoOk(Window win)
{
    <!--Your Code-->
    win.DialogResult = true;
    win.Close();
}

bool CanDoOk(Window win) { return true; }

or similar to what is posted here WPF MVVM: How to close a window

import React, { Component } from "react";
import axios from "axios";

const CancelToken = axios.CancelToken;

let cancel;

class Abc extends Component {

  Api() {
      // Cancel previous request
    if (cancel !== undefined) {
      cancel();
    }
    axios.post(URL, reqBody, {
        cancelToken: new CancelToken(function executor(c) {
          cancel = c;
        }),
      })
      .then((response) => {
        //responce Body
      })
      .catch((error) => {
        if (axios.isCancel(error)) {
          console.log("post Request canceled");
        }
      });
  }

  render() {
    return <h2>cancel Axios Request</h2>;
  }
}

export default Abc;

This whole thread confused the h#$l out of me until I realized you have to be running the debugger to see ANY trace or debug output. I needed a debug output (outside of the debugger) because my WebApp runs fine when I debug it but not when the debugger isn't running (SqlDataSource is instantiated correctly when running through the debugger).

Just because debug output can be seen when you're running in release mode doesn't mean you'll see anything if you're not running the debugger. Careful reading of Writing to output window of Visual Studio? gave me DebugView as an alternative. Extremely useful!

Hopefully this helps anyone else confused by this.

As of Python 3.3, there an easy and direct way to do this with the standard library:

$ cat free_space.py 
#!/usr/bin/env python3

import shutil

total, used, free = shutil.disk_usage(__file__)
print(total, used, free)

$ ./free_space.py 
1007870246912 460794834944 495854989312

These numbers are in bytes. See the documentation for more info.

You cannot source-control the .user files, because that's user specific. It contains the name of remote machine and other user-dependent things. It's a vcproj related file.

The .suo file is a sln related file and it contains the "solution user options" (startup project(s), windows position (what's docked and where, what's floating), etc.)

It's a binary file, and I don't know if it contains something "user related".

In our company we do not take those files under source control.

I've submitted a pull request (available in Ansible 2.2+) that will make this kinds of situations easier by adding jmespath query support on Ansible. In your case it would work like:

- debug: msg="{{ addresses | json_query(\"private_man[?type=='fixed'].addr\") }}"

would return:

ok: [localhost] => {
    "msg": [
        "172.16.1.100"
    ]
}

JAVA_OPTS is environment variable used by tomcat in its startup/shutdown script to configure params.

You can set it in linux by

export JAVA_OPTS="-Djava.awt.headless=true" 

I will reproduce a good tutorial here, because I lost this article and take some time to find it again!

Adding syntax highlighting for new languages to Eclipse with the Colorer library

Say you have an HRC file containing the syntax and lexical structure of some programming language Eclipse does not support (for example D / Iptables or any other script language).

Using the EclipseColorer plugin, you can easily add support for it.

Go to Help -> Install New Software and click Add.. In the Name field write Colorer and in the Location field write http://colorer.sf.net/eclipsecolorer/

Select the entry you’ve just added in the work with: combo box, wait for the component list to populate and click Select All

Click Next and follow the instructions

Once the plugin is installed, close Eclipse.

Copy your HRC file to [EclipseFolder]\plugins\net.sf.colorer_0.9.9\colorer\hrc\auto\types

[EclipseFolder] = /home/myusername/.eclipse

Use your favorite text editor to open

[EclipseFolder]\plugins\net.sf.colorer_0.9.9\colorer\hrc\auto\empty.hrc

Add the appropriate prototype element. For example, if your HRC file is d.hrc, empty.hrc will look like this:

<?xml version="1.0" encoding='Windows-1251'?>
 <!DOCTYPE hrc PUBLIC
 "-//Cail Lomecb//DTD Colorer HRC take5//EN"
 "http://colorer.sf.net/2003/hrc.dtd"
 >
 <hrc version="take5" xmlns="http://colorer.sf.net/2003/hrc"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://colorer.sf.net/2003/hrc http://colorer.sf.net/2003/hrc.xsd"
 ><annotation><documentation>
 'auto' is a place for include
 to colorer your own HRCs
</documentation></annotation>
    <prototype name="d" group="main" description="D">
         <location link="types/d.hrc"/>
        <filename>/\.(d)$/i</filename>
 </prototype>
</hrc>

Save the changes and close the text editor

Open Eclipse and go to Window -> Preferences -> General -> Editors -> File Associations

In the file types section, click Add.. and fill in the appropriate filetype (for example .d)

Click OK and click your newly added entry in the list

In the associated editors section, click Add.., select Colorer Editor and press OK

ok, the hard part is you must learn about HCR syntax.

You can look in

[EclipseFolder]/net.sf.colorer_0.9.9/colorer/hrc/common.jar

to learn how do it and explore many other hcr's files. At this moment I didn't find any documentation.

My gift is a basic and incomplete iptables syntax highlight. If you improve please share with me.

After this you must save the file as iptables.hcr and add inside the jar:

[EclipseFolder]/net.sf.colorer_0.9.9/colorer/hrc/common.jar

Based in: https://ohadsc.wordpress.com/2012/05/26/adding-syntax-highlighting-for-new-languages-to-eclipse-with-the-colorer-library/

What Time Zones?

No where in your question do you mention time zone. What time zone is implied that input string? What time zone do you want for your output? And, UTC is a time zone (or lack thereof depending on your mindset) not a string format.

ISO 8601

Your input string is in ISO 8601 format, except that it lacks an offset from UTC.

Joda-Time

Here is some example code in Joda-Time 2.3 to show you how to handle time zones. Joda-Time has built-in default formatters for parsing and generating String representations of date-time values.

String input = "2013-10-22T01:37:56";
DateTime dateTimeUtc = new DateTime( input, DateTimeZone.UTC );
DateTime dateTimeMontréal = dateTimeUtc.withZone( DateTimeZone.forID( "America/Montreal" );
String output = dateTimeMontréal.toString();

As for generating string representations in other formats, search StackOverflow for "Joda format".

You're missing a closing parenthesis ) in print():

print('{0}+{1}={2}'.format(n1,n2,t1))

and you're also not storing the returned value from int(), so z is still a string.

z = input('?')
z = int(z)

or simply:

z = int(input('?'))

You can add a callback function to your list of get_category(...) parameters.

Ex:

 get_categories(number, callback){
 this.http.post( url, body, {headers: headers, withCredentials:true})
    .subscribe( 
      response => {
        this.total = response.json();
        callback(); 

      }, error => {
    }
  ); 

}

And then you can just call get_category(...) like this:

this.get_category(1, name_of_function);

-print_certs is the option you want to use to list all of the certificates in the p7b file, you may need to specify the format of the p7b file you are reading.

You can then redirect the output to a new file to build the concatenated list of certificates.

Open the file in a text editor, you will either see Base64 (PEM) or binary data (DER).

openssl pkcs7 -inform DER -outform PEM -in certificate.p7b -print_certs > certificate_bundle.cer

http://www.openssl.org/docs/apps/pkcs7.html

itertools.permutations is good, but it doesn't deal nicely with sequences that contain repeated elements. That's because internally it permutes the sequence indices and is oblivious to the sequence item values.

Sure, it's possible to filter the output of itertools.permutations through a set to eliminate the duplicates, but it still wastes time generating those duplicates, and if there are several repeated elements in the base sequence there will be lots of duplicates. Also, using a collection to hold the results wastes RAM, negating the benefit of using an iterator in the first place.

Fortunately, there are more efficient approaches. The code below uses the algorithm of the 14th century Indian mathematician Narayana Pandita, which can be found in the Wikipedia article on Permutation. This ancient algorithm is still one of the fastest known ways to generate permutations in order, and it is quite robust, in that it properly handles permutations that contain repeated elements.

def lexico_permute_string(s):
    ''' Generate all permutations in lexicographic order of string `s`

        This algorithm, due to Narayana Pandita, is from
        https://en.wikipedia.org/wiki/Permutation#Generation_in_lexicographic_order

        To produce the next permutation in lexicographic order of sequence `a`

        1. Find the largest index j such that a[j] < a[j + 1]. If no such index exists, 
        the permutation is the last permutation.
        2. Find the largest index k greater than j such that a[j] < a[k].
        3. Swap the value of a[j] with that of a[k].
        4. Reverse the sequence from a[j + 1] up to and including the final element a[n].
    '''

    a = sorted(s)
    n = len(a) - 1
    while True:
        yield ''.join(a)

        #1. Find the largest index j such that a[j] < a[j + 1]
        for j in range(n-1, -1, -1):
            if a[j] < a[j + 1]:
                break
        else:
            return

        #2. Find the largest index k greater than j such that a[j] < a[k]
        v = a[j]
        for k in range(n, j, -1):
            if v < a[k]:
                break

        #3. Swap the value of a[j] with that of a[k].
        a[j], a[k] = a[k], a[j]

        #4. Reverse the tail of the sequence
        a[j+1:] = a[j+1:][::-1]

for s in lexico_permute_string('data'):
    print(s)

output

aadt
aatd
adat
adta
atad
atda
daat
data
dtaa
taad
tada
tdaa

Of course, if you want to collect the yielded strings into a list you can do

list(lexico_permute_string('data'))

or in recent Python versions:

[*lexico_permute_string('data')]

You could create a function who consumes an list of int, transforms in string to concatenate and cast do int again, something like this:

import random

def generate_random_number(length):
    return int(''.join([str(random.randint(0,10)) for _ in range(length)]))

You need to move the unique_ptr:

vec.push_back(std::move(ptr2x));

unique_ptr guarantees that a single unique_ptr container has ownership of the held pointer. This means that you can't make copies of a unique_ptr (because then two unique_ptrs would have ownership), so you can only move it.

Note, however, that your current use of unique_ptr is incorrect. You cannot use it to manage a pointer to a local variable. The lifetime of a local variable is managed automatically: local variables are destroyed when the block ends (e.g., when the function returns, in this case). You need to dynamically allocate the object:

std::unique_ptr<int> ptr(new int(1));

In C++14 we have an even better way to do so:

make_unique<int>(5);

I don't believe Eclipse has a JavaScript debugger - those breakpoints are for Java code (I'm guessing you are editing a JSP file?)

Use Firebug to debug Javascript code, it's an excellent add-on that all web developers should have in their toolbox.

multi-dimentional frequency count, i.e. counting arrays.

>>> print(color_array    )
  array([[255, 128, 128],
   [255, 128, 128],
   [255, 128, 128],
   ...,
   [255, 128, 128],
   [255, 128, 128],
   [255, 128, 128]], dtype=uint8)


>>> np.unique(color_array,return_counts=True,axis=0)
  (array([[ 60, 151, 161],
    [ 60, 155, 162],
    [ 60, 159, 163],
    [ 61, 143, 162],
    [ 61, 147, 162],
    [ 61, 162, 163],
    [ 62, 166, 164],
    [ 63, 137, 162],
    [ 63, 169, 164],
   array([     1,      2,      2,      1,      4,      1,      1,      2,
         3,      1,      1,      1,      2,      5,      2,      2,

As for me, these are just different methods. The first one leaves the object you're iterating on unchanged, while the seconds leaves it empty. The question is what do you want to do. The complexity of removing is based on implementation of your iterable object. If you're using Collections - just obtain the size like was proposed by Kazekage Gaara - its usually the best approach performance wise.

1. Highlight the range in question.
2. On the Home tab, in the Styles Group, Click "Conditional Formatting".
3. Click "Highlight cell rules"

For the first rule,

Click "greater than", then in the value option box, click on the cell criteria you want it to be less than, than use the format drop-down to select your color.

For the second,

Click "less than", then in the value option box, type "=.9*" and then click the cell criteria, then use the formatting just like step 1.

For the third,

Same as the second, except your formula is =".8*" rather than .9.

As @user786653 suggested, use the xxd(1) program:

xxd -r -p input.txt output.bin

A request to list "Number of employees in each department" or "Display how many people work in each department" is the same as "For each department, list the number of employees", this must include departments with no employees. In the sample database, Operations has 0 employees. So a LEFT OUTER JOIN should be used.

SELECT dept.name, COUNT(emp.empno) AS count
FROM dept
LEFT OUTER JOIN emp ON emp.deptno = dept.deptno
GROUP BY dept.name;

Quentin is correct, it can't be done with CSS. If you want to add a title attribute, you can do it with JavaScript. Here's an example using jQuery:

$('label').attr('title','mandatory');

One thing that caused me a massive headache when using this code (might affect others and I wish that somebody had left a comment like this one here for me to read):

• My aim is to create a dynamic access dashboard, which requires that its linked tables be updated.
• I use the copy methods described above to replace the existing linked CSVs with an updated version of them.
• Running the above code manually from a module worked fine.
• Running identical code from a form linked to the CSV data had runtime error 70 (Permission denied), even tho the first step of my code was to close that form (which should have unlocked the CSV file so that it could be overwritten).
• I now believe that despite the form being closed, it keeps the outdated CSV file locked while it executes VBA associated with that form.

My solution will be to run the code (On timer event) from another hidden form that opens with the database.

No need to get too complicated, try this one liner:

String fileName = new SimpleDateFormat("yyyyMMddHHmm'.txt'").format(new Date());

with ggplot2:

library(ggplot2)
Animals <- read.table(
  header=TRUE, text='Category        Reason Species
1   Decline       Genuine      24
2  Improved       Genuine      16
3  Improved Misclassified      85
4   Decline Misclassified      41
5   Decline     Taxonomic       2
6  Improved     Taxonomic       7
7   Decline       Unclear      41
8  Improved       Unclear     117')

ggplot(Animals, aes(factor(Reason), Species, fill = Category)) + 
  geom_bar(stat="identity", position = "dodge") + 
  scale_fill_brewer(palette = "Set1")

AFAIK this should be pretty fast, but I didn't test it:

def iterate_prv_nxt(my_list):
    prv, cur, nxt = None, iter(my_list), iter(my_list)
    next(nxt, None)

    while True:
        try:
            if prv:
                yield next(prv), next(cur), next(nxt, None)
            else:
                yield None, next(cur), next(nxt, None)
                prv = iter(my_list)
        except StopIteration:
            break

Example usage:

>>> my_list = ['a', 'b', 'c']
>>> for prv, cur, nxt in iterate_prv_nxt(my_list):
...    print prv, cur, nxt
... 
None a b
a b c
b c None

accepted answer doesn't work for me and doesn't follow MDN examples

see the 'Description' section in above link

I'd go with the following it's working for me:

let stringThatIsGoingToChange = 'findMe';
let flagsYouWant = 'gi' //simple string with flags
let dynamicRegExp = new RegExp(`${stringThatIsGoingToChange}`, flagsYouWant)

// that makes dynamicRegExp = /findMe/gi

Try code like this copy and paste in the class

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 100
}

try {
    String command = "Command here";
    Runtime.getRuntime().exec("cmd /c start cmd.exe /K " + command);
} catch (IOException e) {
    e.printStackTrace();
}

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

Store the ticks as a long/bigint, which are currently measured in milliseconds. The updated value can be found by looking at the TimeSpan.TicksPerSecond value.

Most databases have a DateTime type that automatically stores the time as ticks behind the scenes, but in the case of some databases e.g. SqlLite, storing ticks can be a way to store the date.

Most languages allow the easy conversion from Ticks ? TimeSpan ? Ticks.

Example

In C# the code would be:

long TimeAsTicks = TimeAsTimeSpan.Ticks;

TimeAsTimeSpan = TimeSpan.FromTicks(TimeAsTicks);

Be aware though, because in the case of SqlLite, which only offers a small number of different types, which are; INT, REAL and VARCHAR It will be necessary to store the number of ticks as a string or two INT cells combined. This is, because an INT is a 32bit signed number whereas BIGINT is a 64bit signed number.

Note

My personal preference however, would be to store the date and time as an ISO8601 string.

I know this may be a bit old, but try using PDO::lastInsertId. I think it does what you want it to, but you would have to rewrite your application to use PDO (Which is a lot safer against attacks)

How to reproduce this error:

SyntaxError: missing ) after argument list

This code produces the error:

<html>
<body>
<script type="text/javascript" src="jquery-2.1.0.min.js"></script>
<script type="text/javascript">
  $(document).ready(function(){

  }
</script>
</body>
</html>

If you run this and look at the error output in firebug, you get this error. The empty function passed into 'ready' is not closed. Fix it like this:

<html>
<body>
<script type="text/javascript" src="jquery-2.1.0.min.js"></script>
<script type="text/javascript">
  $(document).ready(function(){

  });      //<-- notice the right parenthesis and semicolon
</script>
</body>
</html>

And then the Javascript is interpreted correctly.

When you use the input function it automatically turns it into a string. You need to go:

vote = int(input('Enter the name of the player you wish to vote for'))

which turns the input into a int type value

FormatDateTime(Now, DateFormat.ShortDate)

For Eclipse compiler to work properly you need to remove final/src from the source path and add final/src/main/java instead. This may also solve your problem as now the build directory won't be inside the Java source folder.

Don't use an array if you want named keys, use a plain object.

var a = {};
a["key1"] = "value1";
a["key2"] = "value2";

Then:

if ("key1" in a) {
   // something
} else {
   // something else 
}

In Java there is no good reason.

A couple of other answers have claimed that it's because you can accidentally make it assignment instead of equality. But in Java, you have to have a boolean in an if, so this:

if (o = null)

will not compile.

The only time this could matter in Java is if the variable is boolean:

int m1(boolean x)
{
    if (x = true)  // oops, assignment instead of equality

Not quite, the AND has to be lower-case.

<xsl:when test="4 &lt; 5 and 1 &lt; 2">
<!-- do something -->
</xsl:when>

Android Looper is a wrapper to attach MessageQueue to Thread and it manages Queue processing. It looks very cryptic in Android documentation and many times we may face Looper related UI access issues. If we don't understand the basics it becomes very tough to handle.

Here is an article which explains Looper life cycle, how to use it and usage of Looper in Handler

Looper = Thread + MessageQueue

Try using a div tag and block for span!

<div>
  <span style="padding-right:3px; padding-top: 3px; display:block;">
    <img class="manImg" src="images/ico_mandatory.gif"></img>
  </span>
</div>

While the json begins with "[" and ends with "]" that means this is the Json Array, use JSONArray instead:

JSONArray jsonArray = new JSONArray(JSON);

And then you can map it with the List Test Object if you need:

ObjectMapper mapper = new ObjectMapper();
List<TestExample> listTest = mapper.readValue(String.valueOf(jsonArray), List.class);

You can find remainder using modulo operator Example

a=14
b=10
print(a%b)

It will print 4

There is no default method within HTML itself to insert todays date into the input field. However, like any other input field it will accept a value.

You can use PHP to fetch todays date and input it into the value field of the form element.

<?php
    // Fetch the year, month and day
    $year = date(Y);
    $month = date(m);
    $day = date(d);

    // Merge them into a string accepted by the input field
    $date_string = "$year-$month-$day";

    // Send to the browser the input field with the value set with the date string
    echo "<input type='date' value='$date_string' />";
?>

The value field accepts the format YYYY-MM-DD as an input so simply by creating a variable $date_string in the same format that the input value accepts and fill it with the year, month and day fetched from todays date and voilá! You have yourself a preselected date!

Hope this helps :)

Edit:

If you would like to have the input field nested within HTML rather than PHP you could do the following.

<?php
    // Fetch the year, month and day
    $year = date(Y);
    $month = date(m);
    $day = date(d);

    // Merge them into a string accepted by the input field
    $date_string = "$year-$month-$day";
?>
<html>
    <head>...</head>
    <body>
        <form>
            <input type="date" value="<?php print($date_string); ?>" />
        </form>
    </body>
</html>

I realise this question was asked a while back (2 years ago) but it still took me a while to find a definite answer out on the internet, so this goes to serve anyone who is looking for the answer whenever it may be and hope it helps everyone greatly :)

Another Edit:

Almost forgot, something thats been a royal pain for me in the past is always forgetting to set the default timezone whenever making a script in PHP that makes use of the date() function.

The syntax is date_default_timezone_set(...);. Documentation can be found here at PHP.net and the list of supported timezones to insert into the function can be found here. This was always annoying since I am in Australia, everything is always pushed back 10 hours if I didn't set this properly as it defaults to UTC+0000 where I need UTC+1000 so just be cautious :)

use maven dependency

<dependency> 
  <groupId>org.apache.commons</groupId>
  <artifactId>commons-io</artifactId> 
  <version>1.3.2</version> 
</dependency> 

or download commons-io.1.3.2.jar to your lib folder

This error would happen when the number of guesses (so_far) is less than the length of the word. Did you miss an initialization for the variable so_far somewhere, that sets it to something like

so_far = " " * len(word)

?

Edit:

try something like

print "%d / %d" % (new, so_far)

before the line that throws the error, so you can see exactly what goes wrong. The only thing I can think of is that so_far is in a different scope, and you're not actually using the instance you think.

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

I had this error in Visual Studio 2013, with an SSIS project. I set Project, Properties, Debugging, Run64BitRuntime = false and then the SSIS package ran. However, when I deployed the package to the server I had to set the value to true (Server is 64 bit Windows 2012 / Sql 2014 ).

I think the reasoning behind this is that Visual Studio is a 32 bit application.

There is an another mature and actively developed "player" on the javascript linting front - ESLint:

ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code. In many ways, it is similar to JSLint and JSHint with a few exceptions:

• ESLint uses Esprima for JavaScript parsing.
• ESLint uses an AST to evaluate patterns in code.
• ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime.

What really matters here is that it is extendable via custom plugins/rules. There are already multiple plugins written for different purposes. Among others, there are:

• eslint-plugin-angular (enforces some of the guidelines from John Papa's Angular Style Guide)
• eslint-plugin-jasmine
• eslint-plugin-backbone

And, of course, you can use your build tool of choice to run ESLint:

• grunt-eslint
• gulp-eslint

Each tablespace has one or more datafiles that it uses to store data.

The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.

To find out if the actual limit is 32gb, run the following:

select value from v$parameter where name = 'db_block_size';

Compare the result you get with the first column below, and that will indicate what your max datafile size is.

I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).

Block Sz   Max Datafile Sz (Gb)   Max DB Sz (Tb)

--------   --------------------   --------------

   2,048                  8,192          524,264

   4,096                 16,384        1,048,528

   8,192                 32,768        2,097,056

  16,384                 65,536        4,194,112

  32,768                131,072        8,388,224

You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):

select bytes/1024/1024 as mb_size,
       maxbytes/1024/1024 as maxsize_set,
       x.*
from   dba_data_files x

MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).

If your datafile has a low max size or autoextend is not on you could simply run:

alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;

However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:

alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

OK realized a mistake .. it has to be /:id/:id2

Anyway didn't find this in any tutorial or other StackOverflow question.

@RouteConfig([{path: '/component/:id/:id2',name: 'MyCompB', component:MyCompB}])
export class MyCompA {
    onClick(){
        this._router.navigate( ['MyCompB', {id: "someId", id2: "another ID"}]);
    }
}

This works:

wget -m -np -c --no-check-certificate -R "index.html*" "https://the-eye.eu/public/AudioBooks/Edgar%20Allan%20Poe%20-%2"

To analyze a query you already have entered into the Query editor, you need to choose "Include Actual Execution Plan" (7th toggle button to the right of the "! Execute" button). After executing the query, you need to click on the "Execution Plan" tab in the results pane at the bottom (above the results of the query).

you should use :

ln -s /home/jake/doc/test/2000/something xxx

I believe the Number::Phone::US and Regexp::Common (particularly the source of Regexp::Common::URI::RFC2806) Perl modules could help.

The question should probably be specified in a bit more detail to explain the purpose of validating the numbers. For instance, 911 is a valid number in the US, but 911x isn't for any value of x. That's so that the phone company can calculate when you are done dialing. There are several variations on this issue. But your regex doesn't check the area code portion, so that doesn't seem to be a concern.

Like validating email addresses, even if you have a valid result you can't know if it's assigned to someone until you try it.

If you are trying to validate user input, why not normalize the result and be done with it? If the user puts in a number you can't recognize as a valid number, either save it as inputted or strip out undailable characters. The Number::Phone::Normalize Perl module could be a source of inspiration.

In pthread_exit, ret is an input parameter. You are simply passing the address of a variable to the function.

In pthread_join, ret is an output parameter. You get back a value from the function. Such value can, for example, be set to NULL.

Long explanation:

In pthread_join, you get back the address passed to pthread_exit by the finished thread. If you pass just a plain pointer, it is passed by value so you can't change where it is pointing to. To be able to change the value of the pointer passed to pthread_join, it must be passed as a pointer itself, that is, a pointer to a pointer.

Of these two, the first one is a type mistake: '\0' is a character, not a pointer. The compiler still accepts it because it can convert it to a pointer.

The second one "works" only by coincidence. "\0" is a string literal of two characters. If those occur in multiple places in the source file, the compiler may, but need not, make them identical.

So the proper way to write the first one is

char* array[] = { "abc", "def", NULL };

and you test for array[index]==NULL. The proper way to test for the second one is array[index][0]=='\0'; you may also drop the '\0' in the string (i.e. spell it as "") since that will already include a null byte.

According to this SO link you can print a specific div with

w=window.open();
w.document.write(document.getElementsByClassName('report_left_inner')[0].innerH??TML);
w.print();
w.close();

Use the backslash symbol to escape the space

C:\> cd my folder

will be

 C:\> cd my\folder 

My way, no Spring, used during a unit test:

URI uri = TestClass.class.getResource("/resources").toURI();
Path myPath = Paths.get(uri);
Stream<Path> walk = Files.walk(myPath, 1);
for (Iterator<Path> it = walk.iterator(); it.hasNext(); ) {
    Path filename = it.next();   
    System.out.println(filename);
}

Test for year > 2079. I found that a user typo'ed 2106 instead of 2016 in the year (10/12/2106) and boom; so on 10/12/2016 I tested and found SQL Server accepted up to 2078, started throwing that error if the year is 2079 or higher. I have not done any further research as to what kind of date sliding SQL Server does.

this code is very better for show number in textbox

$(this) = [your textbox]

            var number = $(this).val();
            number = number.replace(/[',]+/g, '');
            number = number.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ',');
            $(this).val(number); // "1,234,567,890"

I have not used BeuatifulSoup but maybe the following can help in some tiny way.

import re
import urllib2
stuff = urllib2.urlopen(your_url_goes_here).read()  # stuff will contain the *entire* page

# Replace the string Python with your desired regex
results = re.findall('(Python)',stuff)

for i in results:
    print i

I'm not suggesting this is a replacement but maybe you can glean some value in the concept until a direct answer comes along.

Most of these answers use sp_executesql as the solution to this problem. I have found that there are some limitations when using sp_executesql, which I will not go into, but I wanted to offer an alternative using EXEC(). I am using SQL Server 2008 and I know that some of the objects I am using in this script are not available in earlier versions of SQL Server so be wary.

DECLARE @CountResults TABLE (CountReturned INT)
DECLARE 
    @SqlStatement VARCHAR(8000) = 'SELECT COUNT(*) FROM table'
    , @Count INT

INSERT @CountResults
EXEC(@SqlStatement)

SET @Count = (SELECT CountReturned FROM @CountResults)
SELECT @Count

I have used

Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_ONE_SHOT);

        Uri defaultSoundUri= RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentTitle("Firebase Push Notification")
                .setContentText(messageBody)
                .setAutoCancel(true)
                .setSound(defaultSoundUri)
                .setContentIntent(pendingIntent);

        NotificationManager notificationManager =
                (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notificationBuilder.build());

Edit: Andrey's answer has been updated so the following no longer applies.

Andrey's answer (the highest voted at the time of writing) is slightly incorrect. I would have added this as comment but I am not reputable enough.

In Andrey's answer:

char[] chars = {'c', 'h', 'a', 'r', 's'}
byte[] bytes = Charset.forName("UTF-8").encode(CharBuffer.wrap(chars)).array();

the call to array() may not return the desired value, for example:

char[] c = "aaaaaaaaaa".toCharArray();
System.out.println(Arrays.toString(Charset.forName("UTF-8").encode(CharBuffer.wrap(c)).array()));

output:

[97, 97, 97, 97, 97, 97, 97, 97, 97, 97, 0]

As can be seen a zero byte has been added. To avoid this use the following:

char[] c = "aaaaaaaaaa".toCharArray();
ByteBuffer bb = Charset.forName("UTF-8").encode(CharBuffer.wrap(c));
byte[] b = new byte[bb.remaining()];
bb.get(b);
System.out.println(Arrays.toString(b));

output:

[97, 97, 97, 97, 97, 97, 97, 97, 97, 97]

As the answer also alluded to using passwords it might be worth blanking out the array that backs the ByteBuffer (accessed via the array() function):

ByteBuffer bb = Charset.forName("UTF-8").encode(CharBuffer.wrap(c));
byte[] b = new byte[bb.remaining()];
bb.get(b);
blankOutByteArray(bb.array());
System.out.println(Arrays.toString(b));

Suppose there are 2 tables TableA and TableB with only 2 columns (Id, Data) and following data:

TableA:

+----+---------+
| Id |  Data   |
+----+---------+
|  1 | DataA11 |
|  1 | DataA12 |
|  1 | DataA13 |
|  2 | DataA21 |
|  3 | DataA31 |
+----+---------+

TableB:

+----+---------+
| Id |  Data   |
+----+---------+
|  1 | DataB11 |
|  2 | DataB21 |
|  2 | DataB22 |
|  2 | DataB23 |
|  4 | DataB41 |
+----+---------+

Inner Join on column Id will return columns from both the tables and only the matching records:

.----.---------.----.---------.
| Id |  Data   | Id |  Data   |
:----+---------+----+---------:
|  1 | DataA11 |  1 | DataB11 |
:----+---------+----+---------:

:----+---------+----+---------:
|  2 | DataA21 |  2 | DataB22 |
:----+---------+----+---------:
|  2 | DataA21 |  2 | DataB23 |
'----'---------'----'---------'

Left Join (or Left Outer join) on column Id will return columns from both the tables and matching records with records from left table (Null values from right table):

.----.---------.----.---------.
| Id |  Data   | Id |  Data   |
:----+---------+----+---------:
|  1 | DataA11 |  1 | DataB11 |
:----+---------+----+---------:

:----+---------+----+---------:
|  2 | DataA21 |  2 | DataB22 |
:----+---------+----+---------:
|  2 | DataA21 |  2 | DataB23 |
:----+---------+----+---------:
|  3 | DataA31 |    |         |
'----'---------'----'---------'

Right Join (or Right Outer join) on column Id will return columns from both the tables and matching records with records from right table (Null values from left table):

+-----------------------------+
¦ Id ¦  Data   ¦ Id ¦  Data   ¦
+----+---------+----+---------¦
¦  1 ¦ DataA11 ¦  1 ¦ DataB11 ¦

¦  2 ¦ DataA21 ¦  2 ¦ DataB23 ¦
¦    ¦         ¦  4 ¦ DataB41 ¦
+-----------------------------+

Full Outer Join on column Id will return columns from both the tables and matching records with records from left table (Null values from right table) and records from right table (Null values from left table):

+-----------------------------+
¦ Id ¦  Data   ¦ Id ¦  Data   ¦
¦----+---------+----+---------¦

For simple cases like here a static variable wrapped inside a static member function is nearly as good. It's simple and will usually be optimized away by compilers. This does not solve initialization order problem for complex objects though.

#include <iostream>

class MyClass 
{

    static const char * const letters(void){
        static const char * const var = "abcdefghijklmnopqrstuvwxyz";
        return var;
    }

    public:
        void show(){
            std::cout << letters() << "\n";
        }
};


int main(){
    MyClass c;
    c.show();
}

You can use $locationChangeStart event to store the previous value in $rootScope or in a service. When you come back, just initialize all previously stored values. Here is a quick demo using $rootScope.

var app = angular.module("myApp", ["ngRoute"]);_x000D_
app.controller("tab1Ctrl", function($scope, $rootScope) {_x000D_
    if ($rootScope.savedScopes) {_x000D_
        for (key in $rootScope.savedScopes) {_x000D_
            $scope[key] = $rootScope.savedScopes[key];_x000D_
        }_x000D_
    }_x000D_
    $scope.$on('$locationChangeStart', function(event, next, current) {_x000D_
        $rootScope.savedScopes = {_x000D_
            name: $scope.name,_x000D_
            age: $scope.age_x000D_
        };_x000D_
    });_x000D_
});_x000D_
app.controller("tab2Ctrl", function($scope) {_x000D_
    $scope.language = "English";_x000D_
});_x000D_
app.config(function($routeProvider) {_x000D_
    $routeProvider_x000D_
        .when("/", {_x000D_
            template: "<h2>Tab1 content</h2>Name: <input ng-model='name'/><br/><br/>Age: <input type='number' ng-model='age' /><h4 style='color: red'>Fill the details and click on Tab2</h4>",_x000D_
            controller: "tab1Ctrl"_x000D_
        })_x000D_
        .when("/tab2", {_x000D_
            template: "<h2>Tab2 content</h2> My language: {{language}}<h4 style='color: red'>Now go back to Tab1</h4>",_x000D_
            controller: "tab2Ctrl"_x000D_

The suggested for loop is quite fine but you have to check the properties with hasOwnProperty. I'd rather suggest using Object.keys() that only returns 'own properties' of the object (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys)

var data = {_x000D_
    "messages": [{_x000D_
        "msgFrom": "13223821242",_x000D_
        "msgBody": "Hi there"_x000D_
    }, {_x000D_
        "msgFrom": "Bill",_x000D_
        "msgBody": "Hello!"_x000D_
    }]_x000D_
};_x000D_
_x000D_
data.messages.forEach(function(message, index) {_x000D_
    console.log('message index '+ index);_x000D_
    Object.keys(message).forEach(function(prop) {    _x000D_
        console.log(prop + " = " + message[prop]);_x000D_
    });_x000D_
});

There is a better why to determine type of an image. with exif_imagetype

If you use this function, you can tell image's real extension.

_{with this function filename's extension is completely irrelevant, which is good.}

function setHeaderContentType(string $filePath): void
{
    $numberToContentTypeMap = [
        '1' => 'image/gif',
        '2' => 'image/jpeg',
        '3' => 'image/png',
        '6' => 'image/bmp',
        '17' => 'image/ico'
    ];

    $contentType = $numberToContentTypeMap[exif_imagetype($filePath)] ?? null;
    
    if ($contentType === null) {
        throw new Exception('Unable to determine content type of file.');
    }

    header("Content-type: $contentType");
}

You can add more types from the link.

Hope it helps.

If your code doesn't cross filesystem boundaries, i.e. you're just working with one filesystem, then use java.io.File.separator.

This will, as explained, get you the default separator for your FS. As Bringer128 explained, System.getProperty("file.separator") can be overriden via command line options and isn't as type safe as java.io.File.separator.

The last one, java.nio.file.FileSystems.getDefault().getSeparator(); was introduced in Java 7, so you might as well ignore it for now if you want your code to be portable across older Java versions.

So, every one of these options is almost the same as others, but not quite. Choose one that suits your needs.

If you are looking for a real simple way to log, you can use this one liner. If the file doesn't exist, it's created.

System.IO.File.AppendAllText(@"c:\log.txt", "mymsg\n");

The jQuery constructor accepts a 2nd parameter called context which can be used to override the context of the selection.

jQuery("img", this);

Which is the same as using .find() like this:

jQuery(this).find("img");

If the imgs you desire are only direct descendants of the clicked element, you can also use .children():

jQuery(this).children("img");

The command scp can be used like a traditional UNIX cp. SO if you do :

scp -r myDirectory/ mylogin@host:TargetDirectory

will work

The actually correct and convenient answer for python 3:

>>> import codecs
>>> myString = "spam\\neggs"
>>> print(codecs.escape_decode(bytes(myString, "utf-8"))[0].decode("utf-8"))
spam
eggs
>>> myString = "naïve \\t test"
>>> print(codecs.escape_decode(bytes(myString, "utf-8"))[0].decode("utf-8"))
naïve    test

Details regarding codecs.escape_decode:

• codecs.escape_decode is a bytes-to-bytes decoder
• codecs.escape_decode decodes ascii escape sequences, such as: b"\\n" -> b"\n", b"\\xce" -> b"\xce".
• codecs.escape_decode does not care or need to know about the byte object's encoding, but the encoding of the escaped bytes should match the encoding of the rest of the object.

Background:

• @rspeer is correct: unicode_escape is the incorrect solution for python3. This is because unicode_escape decodes escaped bytes, then decodes bytes to unicode string, but receives no information regarding which codec to use for the second operation.
• @Jerub is correct: avoid the AST or eval.
• I first discovered codecs.escape_decode from this answer to "how do I .decode('string-escape') in Python3?". As that answer states, that function is currently not documented for python 3.

have a look at something like this:

<form role="form">  
    <div class="row">
      <div class="col-xs-12">
        <div class="input-group input-group-lg">
            <input type="text" class="form-control" />
          <div class="input-group-btn">

In chrome, your best option might be the Snippets tab under Sources in the Developer Tools.

It will allow you to write and run code, for example, in a about:blank page.

More information here: https://developers.google.com/web/tools/chrome-devtools/debug/snippets/?hl=en

rem set defaults:
set filename1="c:\file1.txt"

IF NOT "a%2"=="a" (set filename2="%2")
IF NOT "a%3"=="a" (set filename1="%3")
echo %filename1%, %filename2%, %filename3%

Be careful with quotation characters though, you may or may not need them in your variables.
