If you are producing the entire output yourself, you can use sprintf(), e.g.

> sprintf("%.10f",0.25)
[1] "0.2500000000"

specifies that you want to format a floating point number with ten decimal points (in %.10f the f is for float and the .10 specifies ten decimal points).

I don't know of any way of forcing R's higher level functions to print an exact number of digits.

Displaying 100 digits does not make sense if you are printing R's usual numbers, since the best accuracy you can get using 64-bit doubles is around 16 decimal digits (look at .Machine$double.eps on your system). The remaining digits will just be junk.

You have so many choices, how could you be confused :-)? The main controls are:

# \pset format
# \H
# \x
# \pset pager off

Each has options and interactions with the others. The most automatic options are:

# \x off;\pset format wrapped
# \x auto

The newer "\x auto" option switches to line-by-line display only "if needed".

-[ RECORD 1 ]---------------

The older "\pset format wrapped" is similar in that it tries to fit the data neatly on screen, but falls back to unaligned if the headers won't fit. Here's an example of wrapped:

 id |          description           |            authority

This sounds like you're using numpy.

If that's the case, you can add:

import numpy as np
np.set_printoptions(threshold=np.nan)

That will disable the corner printing. For more information, see this NumPy Tutorial.

For me, as I was storing many values within a single print call, the solution was to create a separate variable to store the data as a tuple and then call the print function.

x = (f"{id}", f"{name}", f"{age}")
print(x) 

My answer is intended for comment though but since i havent got enough reputation, i think it will still be relevant as an answer and help some one.

I find datatable in library DT robust to handle rownames, and columnames

Library DT
datatable(df, rownames = FALSE)  # no row names 

refer to https://rstudio.github.io/DT/ for usage scenarios

The following answer applies to a Spark Streaming application.

By setting the "truncate" option to false, you can tell the output sink to display the full column.

val query = out.writeStream
          .outputMode(OutputMode.Update())
          .format("console")
          .option("truncate", false)
          .trigger(Trigger.ProcessingTime("5 seconds"))
          .start()

If someone looking for a way to display decimal places even if it ends with ".00", use this:

String.Format("{0:n1}", value)

Reference:

https://docs.microsoft.com/pt-br/dotnet/standard/base-types/standard-numeric-format-strings#the-numeric-n-format-specifier

You don't need to wait. Protractor automatically waits for angular to be ready and then it executes the next step in the control flow.

Checking for existence of an element is documented neatly in the official jQuery website itself!

Use the .length property of the jQuery collection returned by your selector:

if ($("#myDiv").length) {
    $("#myDiv").show();
}

Note that it isn't always necessary to test whether an element exists. The following code will show the element if it exists, and do nothing (with no errors) if it does not:

$("#myDiv").show();

To know about all methods use this statement in console:

javap -cp jar-file.jar packagename.classname

or

javap class-file.class packagename.classname

or for example:

javap java.lang.StringBuffer

Simple script to remove given tag from both local and origin locations. With a check if tag really exists.

if [ $(git tag -l "$1") ]; then
    git tag --delete  $1
    git push --delete origin $1

    echo done.
else
    echo tag named "$1" was not found
fi

How to use:

• Create shell script file (e.g. git-tag-purge.sh) and paste content.
• chmod your script file to make it executable.
• Make the script globally available
• cd to your git project
• Call script (e.g.

  $>git-tag-purge.sh tag_name

  )

The python 2.5 documentation explains it well.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is ordered first (for example, [1,2] < [1,2,3]).

Unfortunately that page seems to have disappeared in the documentation for more recent versions.

The links are wrong, you have to do this:

<ul class="nav navbar-nav item">
    <li>
        <a [routerLink]="['/home']" routerLinkActive="active">Home</a>
    </li>
    <li>
        <a [routerLink]="['/about']" routerLinkActive="active">About this
        </a>
    </li>
</ul>

In the accepted answer PREMKUMAR there are a couple of errors in his Complete code in Swift answer. First print should read (appendString) and Second print should read (appendString1). Also, updated println deprecated in Swift 2.0

His

let string1 = "This is"
let string2 = "Swift Language"
var appendString = "\(string1) \(string2)"
var appendString1 = string1+string2
println("APPEND STRING1:\(appendString1)")
println("APPEND STRING2:\(appendString2)")

Corrected

let string1 = "This is"
let string2 = "Swift Language"
var appendString = "\(string1) \(string2)"
var appendString1 = string1+string2
print("APPEND STRING:\(appendString)")
print("APPEND STRING1:\(appendString1)")

OK Here is a Good And Proper Solution

You have a Div call with an id="myDiv"

so the function goes.

function GetScrollerEndPoint()
{
   var scrollHeight = $("#myDiv").prop('scrollHeight');
   var divHeight = $("#myDiv").height();
   var scrollerEndPoint = scrollHeight - divHeight;

   var divScrollerTop =  $("#myDiv").scrollTop();
   if(divScrollerTop === scrollerEndPoint)
   {
       //Your Code 
       //The Div scroller has reached the bottom
   }
}

i found an easy solution, export the database, edit it what you want to edit in a text editor, then import it. Done

Here’s some PHP and JavaScript demonstration code that shows a simple way to create indexed fields on a form (fields that have the same name) and then process them in both JavaScript and PHP. The fields must have both "ID" names and "NAME" names. Javascript uses the ID and PHP uses the NAME.

<?php
// How to use same field name multiple times on form
// Process these fields in Javascript and PHP
// Must use "ID" in Javascript and "NAME" in PHP 
echo "<HTML>";
echo "<HEAD>";
?>
<script type="text/javascript">
function TestForm(form) {
// Loop through the HTML form field (TheId) that is returned as an array. 
// The form field has multiple (n) occurrences on the form, each which has the same name.
// This results in the return of an array of elements indexed from 0 to n-1.
// Use ID  in Javascript
var i = 0;
document.write("<P>Javascript responding to your button click:</P>");
for (i=0; i < form.TheId.length; i++) {
  document.write(form.TheId[i].value);
  document.write("<br>");
}  
}
</script>
<?php
echo "</HEAD>";
echo "<BODY>";
$DQ = '"';  # Constant for building string with double quotes in it.

if (isset($_POST["MyButton"])) {
  $TheNameArray = $_POST["TheName"];  # Use NAME in PHP
  echo "<P>Here are the names you submitted to server:</P>";
  for ($i = 0; $i <3; $i++) {   
    echo $TheNameArray[$i] . "<BR>";
  } 
}
echo "<P>Enter names and submit to server or Javascript</P>";
echo "<FORM NAME=TstForm METHOD=POST ACTION=" ;
echo $DQ . "TestArrayFormToJavascript2.php" . $DQ . "OnReset=" . $DQ . "return allowreset(this)" . $DQ . ">";
echo "<FORM>";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<INPUT ID = TheId NAME=" . $DQ . "TheName[]" . $DQ . " VALUE=" . $DQ . "" . $DQ . ">";
echo "<P><INPUT TYPE=submit NAME=MyButton VALUE=" . $DQ . "Submit to server"    . $DQ . "></P>";
echo "<P><BUTTON onclick=" . $DQ . "TestForm(this.form)" . $DQ . ">Submit to Javascript</BUTTON></P>"; 
echo "</FORM>";
echo "</BODY>";
echo "</HTML>";

Make sure to target x86 on your project in Visual Studio. This should fix your trouble.

hi array is one object so it null type or blank

   <?php
        if($error!=null)
            echo "array is blank or null or not array";
    //OR
       if(!empty($error))
           echo "array is blank or null or not array";
    //OR
     if(is_array($error))
           echo "array is blank or null or not array";
   ?>

If you're using more recent Android APIs the Handler empty constructor has been deprecated and you should include a Looper. You can easily get one through Looper.getMainLooper().

    Handler(Looper.getMainLooper()).postDelayed({
        //Your code
    }, 2000) //millis

First convert it to std::wstring:

std::wstring widestr = std::wstring(str.begin(), str.end());

Then get the C string:

const wchar_t* widecstr = widestr.c_str();

This only works for ASCII strings, but it will not work if the underlying string is UTF-8 encoded. Using a conversion routine like MultiByteToWideChar() ensures that this scenario is handled properly.

I had the similar problem with eclipse kepler.I have followed these steps to resolve it

• Go to Help in Eclipse and Oper Eclipse Market Place option.
• Search for jdk 1.8 for kepler
• Install the required plugin.
• Restart the eclipse.

for reference, refer this link http://techno-terminal.blogspot.in/2016/05/jdk-18-compiler-compliance-is-not.html

If condition is wrong. Also return type for lower is needed.

#include <stdio.h>

int lower(int a)  
{
    if ((a >= 65) && (a <= 90))
        a = a + 32; 
    return a;  
}

int _tmain(int argc, _TCHAR* argv[])
{

    putchar(lower('A')); 
    return 0;
}

A Windows load event fires when all the content on your page is fully loaded including the DOM (document object model) content and asynchronous JavaScript, frames and images. You can also use body onload=. Both are the same; window.onload = function(){} and <body onload="func();"> are different ways of using the same event.

jQuery $document.ready function event executes a bit earlier than window.onload and is called once the DOM(Document object model) is loaded on your page. It will not wait for the images, frames to get fully load.

Taken from the following article: how $document.ready() is different from window.onload()

This is not a generic answer.

However: Some programs, especially services and long-running programs, create (or offer to create, optionally) a "pid file".

For instance, LibreOffice offers --pidfile={file}, see the docs.

I was looking for quite some time for a Java/Linux solution but the PID was (in my case) lying at hand.

Dont use spaces:

SET @var="GREG"
::instead of SET @var = "GREG"
ECHO %@var%
PAUSE

1. If you have used an installer, you can uninstall golang by using the same installer.
2. If you have installed from source

   rm -rf /usr/local/go
   rm -rf $(echo $GOPATH)
   

Then, remove all entries related to go i.e. GOROOT, GOPATH from ~/.bash_profile and run

source ~/.bash_profile

On a Linux system

rm -rf /usr/local/go
rm -rf $(echo $GOPATH)

Then, remove all entries related to go i.e. GOROOT, GOPATH from ~/.bashrc and run

source ~/.bashrc

The result of a subtraction generating a negative number in an unsigned type is well-defined:

1. [...] A computation involving unsigned operands can never overflow, because a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting type. (ISO/IEC 9899:1999 (E) §6.2.5/9)

As you can see, (unsigned)0 - (unsigned)1 equals -1 modulo UINT_MAX+1, or in other words, UINT_MAX.

Note that although it does say "A computation involving unsigned operands can never overflow", which might lead you to believe that it applies only for exceeding the upper limit, this is presented as a motivation for the actual binding part of the sentence: "a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting type." This phrase is not restricted to overflow of the upper bound of the type, and applies equally to values too low to be represented.

Just put hello() somewhere below the function and it will execute when you do python your_file.py

For a neater solution you can use this:

if __name__ == '__main__':
    hello()

That way the function will only be executed if you run the file, not when you import the file.

In C++, a constructor with only one required parameter is considered an implicit conversion function. It converts the parameter type to the class type. Whether this is a good thing or not depends on the semantics of the constructor.

For example, if you have a string class with constructor String(const char* s), that's probably exactly what you want. You can pass a const char* to a function expecting a String, and the compiler will automatically construct a temporary String object for you.

On the other hand, if you have a buffer class whose constructor Buffer(int size) takes the size of the buffer in bytes, you probably don't want the compiler to quietly turn ints into Buffers. To prevent that, you declare the constructor with the explicit keyword:

class Buffer { explicit Buffer(int size); ... }

That way,

void useBuffer(Buffer& buf);
useBuffer(4);

becomes a compile-time error. If you want to pass a temporary Buffer object, you have to do so explicitly:

useBuffer(Buffer(4));

In summary, if your single-parameter constructor converts the parameter into an object of your class, you probably don't want to use the explicit keyword. But if you have a constructor that simply happens to take a single parameter, you should declare it as explicit to prevent the compiler from surprising you with unexpected conversions.

Add a contextmenu to your form and then assign it in the control's properties under ContextMenuStrip. Hope this helps :).

Hope this helps:

ContextMenu cm = new ContextMenu();
cm.MenuItems.Add("Item 1");
cm.MenuItems.Add("Item 2");

pictureBox1.ContextMenu = cm;

If you want to set the Cache-Control header, there's nothing in the IIS7 UI to do this, sadly.

You can however drop this web.config in the root of the folder or site where you want to set it:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.webServer>
    <staticContent>
      <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="7.00:00:00" />
    </staticContent>
  </system.webServer>
</configuration>

That will inform the client to cache content for 7 days in that folder and all subfolders.

You can also do this by editing the IIS7 metabase via appcmd.exe, like so:

\Windows\system32\inetsrv\appcmd.exe 
  set config "Default Web Site/folder" 
  -section:system.webServer/staticContent 
  -clientCache.cacheControlMode:UseMaxAge

\Windows\system32\inetsrv\appcmd.exe 
  set config "Default Web Site/folder" 
  -section:system.webServer/staticContent 
  -clientCache.cacheControlMaxAge:"7.00:00:00"

I've used them as static variables for a function. For example, given the following C code:

int fn(int i)
{
    static f = 1;
    f += i;
    return f;
}

I can implement the function similarly in Python:

def fn(i):
    fn.f += i
    return fn.f
fn.f = 1

This would definitely fall into the "abuses" end of the spectrum.

IN xampp just export the required table as a .sql file and then import it to the required

You can try this:

s = r'long\annoying\path'

well you are returning an array of items from the database. so you need something like this.

   $dave= mysql_query("SELECT order_date, no_of_items, shipping_charge, 
    SUM(total_order_amount) as test FROM `orders` 
    WHERE DATE(`order_date`) = DATE(NOW()) GROUP BY DATE(`order_date`)") 
    or  die(mysql_error());


while ($row = mysql_fetch_assoc($dave)) {
echo $row['order_date'];
echo $row['no_of_items'];
echo $row['shipping_charge'];
echo $row['test '];
}

You can use the Class XmlAttribute.

Eg:

XmlAttribute attr = xmlDoc.CreateAttribute("userName");
attr.Value = "Tushar";

node.Attributes.Append(attr);

I deleted the project without removing content. I then created a new Java project from an existing resource. Pointing at my SVN checkout root folder. This worked for me. Although, Chris' way would have been much quicker. That's good to note for future. Thanks!

Let's say you have:

<a></a>

<(.*)> would match a></a where as <(.*?)> would match a. The latter stops after the first match of >. It checks for one or 0 matches of .* followed by the next expression.

The first expression <(.*)> doesn't stop when matching the first >. It will continue until the last match of >.

For me, I had ~6 different Nuget packages to update and when I selected Microsoft.AspNetCore.All first, I got the referenced error.

I started at the bottom and updated others first (EF Core, EF Design Tools, etc), then when the only one that was left was Microsoft.AspNetCore.All it worked fine.

In Nexus 5, Go to Settings -> Google -> Security and uncheck "Scan device for Security threats" and "Improve harmful app detection".

It depends on the language and the exact use. For instance, in C# 1 it made no difference. In C# 2, if the local variable is captured by an anonymous method (or lambda expression in C# 3) it can make a very signficant difference.

Example:

using System;
using System.Collections.Generic;

class Test
{
    static void Main()
    {
        List<Action> actions = new List<Action>();

        int outer;
        for (int i=0; i < 10; i++)
        {
            outer = i;
            int inner = i;
            actions.Add(() => Console.WriteLine("Inner={0}, Outer={1}", inner, outer));
        }

        foreach (Action action in actions)
        {
            action();
        }
    }
}

Output:

Inner=0, Outer=9
Inner=1, Outer=9
Inner=2, Outer=9
Inner=3, Outer=9
Inner=4, Outer=9
Inner=5, Outer=9
Inner=6, Outer=9
Inner=7, Outer=9
Inner=8, Outer=9
Inner=9, Outer=9

The difference is that all of the actions capture the same outer variable, but each has its own separate inner variable.

Here is the way I look at COALESCE...and hopefully it makes sense...

In a simplistic form….

Coalesce(FieldName, 'Empty')

So this translates to…If "FieldName" is NULL, populate the field value with the word "EMPTY".

Now for mutliple values...

Coalesce(FieldName1, FieldName2, Value2, Value3)

If the value in Fieldname1 is null, fill it with the value in Fieldname2, if FieldName2 is NULL, fill it with Value2, etc.

This piece of test code for the AdventureWorks2012 sample database works perfectly & gives a good visual explanation of how COALESCE works:

SELECT Name, Class, Color, ProductNumber,
COALESCE(Class, Color, ProductNumber) AS FirstNotNull
FROM Production.Product

You need to add the package containing the executable pg_config.

A prior answer should have details you need: pg_config executable not found

To center align text

input[type='text'] { text-align:center;}

To center align the textbox in the container that it sits in, apply text-align:center to the container.

Full Path for it is

System.Configuration.ConfigurationManager.AppSettings["KeyName"]

Use this code with a closure (introduced in PHP 5.3), it's a bit faster than the accepted answer and for me, the intention to cast it to an integer, is clearer:

// if you have your values in the format '1,2,3,4', use this before:
// $stringArray = explode(',', '1,2,3,4');

$stringArray = ['1', '2', '3', '4'];

$intArray = array_map(
    function($value) { return (int)$value; },
    $stringArray
);

var_dump($intArray);

Output will be:

array(4) {
  [0]=>
  int(1)
  [1]=>
  int(2)
  [2]=>
  int(3)
  [3]=>
  int(4)
}

Check the modulus of each integer from 2 up to the root of the number you're checking.

If modulus equals zero then it's not prime.

pseudo code:

bool IsPrime(int target)
{
  for (i = 2; i <= root(target); i++)
  {
    if ((target mod i) == 0)
    {
      return false;
    }
  }

  return true;
}

I suspect that the jar files of hibernate-core and hibernate-entitymanager dependencies are corrupted or were not installed properly on your machine.

I suggest that you just delete the folders named hibernate-core and hibernate-entitymanager from your Maven local repository and Maven will reinstall them.

The default location for Maven local repository is C:\Documents and Settings\[USERNAME]\.m2 in windows or ~/.m2 in Linux/Mac.

public mySentences:Array<any> = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

OR

public mySentences:Array<object> = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

DocumentElement is the root node of the document so childNodes[1] doesn't exist in that document. childNodes[0] would be the <Settings> node

You can use the command find to do this. We can match files with -type f, and match empty files using -size 0. Then we can delete the matches with -delete.

find . -type f -size 0 -delete

Here is one way to do this using css

HTML

<div class="imageWrapper">
    <img src="http://lorempixel.com/300/300/" alt="" />
    <a href="http://google.com" class="cornerLink">Link</a>
</div>?

CSS

.imageWrapper {
    position: relative;
    width: 300px;
    height: 300px;
}
.imageWrapper img {
    display: block;
}
.imageWrapper .cornerLink {
    opacity: 0;
    position: absolute;
    bottom: 0px;
    left: 0px;
    right: 0px;
    padding: 2px 0px;
    color: #ffffff;
    background: #000000;
    text-decoration: none;
    text-align: center;
    -webkit-transition: opacity 500ms;
    -moz-transition: opacity 500ms;
    -o-transition: opacity 500ms;
    transition: opacity 500ms;

}
.imageWrapper:hover .cornerLink {
    opacity: 0.8;
}

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

I changed 3 things and then it works:

1. There is a column of spaces, I removed them
2. Changed the line break from windows CRLF to linux LF
3. Removed the empty line at the end.

In my case, package python-pygments was missed. You can fix it by command:

sudo apt-get install python-pygments

If there is problem with pandoc. You should install pandoc and pandoc-citeproc.

sudo apt-get install pandoc pandoc-citeproc

In my case I had in one report many different datasets to DB and Analysis Services Cube. Looks like that datasets blocked each other and generated such error. For me helped option "Use single transaction when processing the queries" in the CUBE datasource properties

First create a <span id="decodeIt" style="display:none;"></span> somewhere in the body

Next, assign the string to be decoded as innerHTML to this:

document.getElementById("decodeIt").innerHTML=stringtodecode

Finally,

stringtodecode=document.getElementById("decodeIt").innerText

Here is the overall code:

var stringtodecode="<B>Hello</B> world<br>";
document.getElementById("decodeIt").innerHTML=stringtodecode;
stringtodecode=document.getElementById("decodeIt").innerText

I had the exact same conundrum when unit testing an Android app, and the easiest solution I came up with was simply to use Gson to convert my actual and expected value objects into json and compare them as strings.

String actual = new Gson().toJson( myObj.getValues() );
String expected = new Gson().toJson( new MyValues(true,1) );

assertEquals(expected, actual);

The advantages of this over manually comparing field-by-field is that you compare all your fields, so even if you later on add a new field to your class it will get automatically tested, as compared to if you were using a bunch of assertEquals() on all the fields, which would then need to be updated if you add more fields to your class.

jUnit also displays the strings for you so you can directly see where they differ. Not sure how reliable the field ordering by Gson is though, that could be a potential problem.

Edit:

  <form (submit)="submit()" >
    <input />
    <button type="submit" style="display:none">hidden submit</button>
  </form>

In order to use this method, you need to have a submit button even if it's not displayed "Thanks for Toolkit's answer"

Old Answer:

Yes, exactly as you wrote it, except the event name is (submit) instead of (ngSubmit):

<form [ngFormModel]="xxx" (submit)="xxxx()">
  <input [(ngModel)]="lxxR"   ngControl="xxxxx"/>
</form>

I've discovered that LEFT and RIGHT are not supported functions in Oracle. They are used in SQL Server, MySQL, and some other versions of SQL. In Oracle, you need to use the SUBSTR function. Here are simple examples:

LEFT ('Data', 2) = 'Da'

->   SUBSTR('Data',1,2) = 'Da'

RIGHT ('Data', 2) = 'ta'

->   SUBSTR('Data',-2,2) = 'ta'

Notice that a negative number counts back from the end.

You could use addEventListener to add as many listeners as you want.

  document.getElementById("Save").addEventListener('click',function ()
    {
     alert("hello");
     //validation code to see State field is mandatory.  
    }  ); 

Also add script tag after the element to make sure Save element is loaded at the time when script runs

Rather than moving script tag you could call it when dom is loaded. Then you should place your code inside the

document.addEventListener('DOMContentLoaded', function() {
    document.getElementById("Save").addEventListener('click',function ()
    {
     alert("hello");
     //validation code to see State field is mandatory.  
    }  ); 
});

example

How about:

import re

s = "alpha.Customer[cus_Y4o9qMEZAugtnW] ..."
m = re.search(r"\[([A-Za-z0-9_]+)\]", s)
print m.group(1)

For me this prints:

cus_Y4o9qMEZAugtnW

Note that the call to re.search(...) finds the first match to the regular expression, so it doesn't find the [card] unless you repeat the search a second time.

Edit: The regular expression here is a python raw string literal, which basically means the backslashes are not treated as special characters and are passed through to the re.search() method unchanged. The parts of the regular expression are:

1. \[ matches a literal [ character
2. ( begins a new group
3. [A-Za-z0-9_] is a character set matching any letter (capital or lower case), digit or underscore
4. + matches the preceding element (the character set) one or more times.
5. ) ends the group
6. \] matches a literal ] character

Edit: As D K has pointed out, the regular expression could be simplified to:

m = re.search(r"\[(\w+)\]", s)

since the \w is a special sequence which means the same thing as [a-zA-Z0-9_] depending on the re.LOCALE and re.UNICODE settings.

The GeoCoordinate class (.NET Framework 4 and higher) already has GetDistanceTo method.

var sCoord = new GeoCoordinate(sLatitude, sLongitude);
var eCoord = new GeoCoordinate(eLatitude, eLongitude);

return sCoord.GetDistanceTo(eCoord);

The distance is in meters.

You need to reference System.Device.

Using function in typescript

openWindow(){
    //you may choose to deduct some value from current screen size
    let height = window.screen.availHeight-100;
    let width = window.screen.availWidth-150;
    window.open("http://your_url",`width=${width},height=${height}`);
}

Yes, the moment jQuery sees the URL belongs to a different domain, it assumes that call as a cross domain call, thus crossdomain:true is not required here.

Also, important to note that you cannot make a synchronous call with $.ajax if your URL belongs to a different domain (cross domain) or you are using JSONP. Only async calls are allowed.

Note: you can call the service synchronously if you specify the async:false with your request.

public String UpperCaseWords(String line)
{
    line = line.trim().toLowerCase();
    String data[] = line.split("\\s");
    line = "";
    for(int i =0;i< data.length;i++)
    {
        if(data[i].length()>1)
            line = line + data[i].substring(0,1).toUpperCase()+data[i].substring(1)+" ";
        else
            line = line + data[i].toUpperCase();
    }
    return line.trim();
}

From the selectors specification:

Attribute values must be CSS identifiers or strings.

Identifiers cannot start with a number. Strings must be quoted.

1 is therefore neither a valid identifier nor a string.

Use "1" (which is a string) instead.

var a = document.querySelector('a[data-a="1"]');

MySQL will truncate any insert value that exceeds the specified column width.

to make this without error try switch your SQL mode to not use STRICT.

Mysql reference manual

EDIT:

To change the mode

This can be done in two ways:

1. Open your my.ini (Windows) or my.cnf (Unix) file within the MySQL installation directory, and look for the text "sql-mode".

Find:

Code:

# Set the SQL mode to strict 
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Replace with:

Code:

# Set the SQL mode to strict 
sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

Or

2. You can run an SQL query within your database management tool, such as phpMyAdmin:

Code:

SET @@global.sql_mode= '';

You can recursively merge them into one as follows:

function mergeRecursive(obj1, obj2) {_x000D_
    for (var p in obj2) {_x000D_
        try {_x000D_
            // Property in destination object set; update its value._x000D_
            if (obj2[p].constructor == Object) {_x000D_
                obj1[p] = this.mergeRecursive(obj1[p], obj2[p]);_x000D_
_x000D_
            } else {_x000D_
                obj1[p] = obj2[p];_x000D_
_x000D_
            }_x000D_
_x000D_
        } catch (e) {_x000D_
            obj1[p] = obj2[p];_x000D_
_x000D_
        }_x000D_
    }_x000D_
    return obj1;_x000D_
}_x000D_
_x000D_
arr1 = [_x000D_
    { id: "abdc4051", date: "2017-01-24" },_x000D_
    { id: "abdc4052", date: "2017-01-22" }_x000D_

arr2 = [_x000D_

_x000D_
mergeRecursive(arr1, arr2)_x000D_
console.log(JSON.stringify(arr1))

One reason why you might prefer to use a JOIN rather than NOT IN is that if the Values in the NOT IN clause contain any NULLs you will always get back no results. If you do use NOT IN remember to always consider whether the sub query might bring back a NULL value!

RE: Question in Comments

'x' NOT IN (NULL,'a','b')

= 'x' <> NULL and 'x' <> 'a' and 'x' <> 'b'

= Unknown and True and True

= Unknown

Try this

new_df = pd.merge(A_df, B_df,  how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.merge.html

left_on : label or list, or array-like Field names to join on in left DataFrame. Can be a vector or list of vectors of the length of the DataFrame to use a particular vector as the join key instead of columns

right_on : label or list, or array-like Field names to join on in right DataFrame or vector/list of vectors per left_on docs

Combining much of above here is my real practical example, selecting records based on both meterid & timestamp. I have needed this command for years. Executes really quickly.

mysqldump -uuser -ppassword main_dbo trHourly --where="MeterID =5406 AND TIMESTAMP<'2014-10-13 05:00:00'" --no-create-info --skip-extended-insert | grep  '^INSERT' > 5406.sql

Why not have a setSize method.

A* arrayOfAs = new A[5];
for (int i = 0; i < 5; ++i)
{
    arrayOfAs[i].SetSize(3);
}

I like the "copy" but in this case the default constructor isn't really doing anything. The SetSize could copy the data out of the original m_array (if it exists).. You'd have to store the size of the array within the class to do that.
OR
The SetSize could delete the original m_array.

void SetSize(unsigned int p_newSize)
{
    //I don't care if it's null because delete is smart enough to deal with that.
    delete myArray;
    myArray = new int[p_newSize];
    ASSERT(myArray);
}

Since Spring 5 you just need to implement the interface WebMvcConfigurer:

public class MvcConfig implements WebMvcConfigurer {

This is because Java 8 introduced default methods on interfaces which cover the functionality of the WebMvcConfigurerAdapter class

See here:

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/servlet/config/annotation/WebMvcConfigurerAdapter.html

An abstract class can not be directly instantiated, but must be derived from to be usable. A class MUST be abstract if it contains abstract methods: either directly

abstract class Foo {
    abstract void someMethod();
}

or indirectly

interface IFoo {
    void someMethod();
}

abstract class Foo2 implements IFoo {
}

However, a class can be abstract without containing abstract methods. Its a way to prevent direct instantation, e.g.

abstract class Foo3 {
}

class Bar extends Foo3 {

}

Foo3 myVar = new Foo3(); // illegal! class is abstract
Foo3 myVar = new Bar(); // allowed!

The latter style of abstract classes may be used to create "interface-like" classes. Unlike interfaces an abstract class is allowed to contain non-abstract methods and instance variables. You can use this to provide some base functionality to extending classes.

Another frequent pattern is to implement the main functionality in the abstract class and define part of the algorithm in an abstract method to be implemented by an extending class. Stupid example:

abstract class Processor {
    protected abstract int[] filterInput(int[] unfiltered);

    public int process(int[] values) {
        int[] filtered = filterInput(values);
        // do something with filtered input
    }
}

class EvenValues extends Processor {
    protected int[] filterInput(int[] unfiltered) {
        // remove odd numbers
    }
}

class OddValues extends Processor {
    protected int[] filterInput(int[] unfiltered) {
        // remove even numbers
    }
}

use Jackson (https://github.com/FasterXML/jackson) from http://json.org/

HashMap<String,Object> result =
       new ObjectMapper().readValue(<JSON_OBJECT>, HashMap.class);

Putting my two cents here. I wanted to do the same without hardcoding the URL for my specific request. So i came up with this solution.

To append 'api' to my baseURL, I have my default baseURL set as,

axios.defaults.baseURL = '/api/';

Then in my specific request, after explicitly setting the method and url, i set the baseURL to '/'

axios({
    method:'post',
    url:'logout',
    baseURL: '/',
   })
   .then(response => {
      window.location.reload();
   })
   .catch(error => {
       console.log(error);
   });

The problem with MVC is that even for "experts" it eats up a lot of valuable time and requires lot of effort. Businesses are driven by the basic thing "Quick Solution that works" regardless of technology behind it. WebForms is a RAD technology that saves time and money. Anything that requires more time is not acceptable by businesses.

Every time I use finish to close the fragment, the entire activity closes. According to the docs, fragments should remain as long as the parent activity remains.

Instead, I found that I can change views back the the parent activity by using this statement: setContentView(R.layout.activity_main);

This returns me back to the parent activity.

I hope that this helps someone else who may be looking for this.

I saw this post about a month ago when I was having similar problems. I needed y-axis scrolling for a table inside of a ui dialog (yes, you heard me right). I was lucky, in that a working solution presented itself fairly quickly. However, it wasn't long before the solution took on a life of its own, but more on that later.

The problem with just setting the top level elements (thead, tfoot, and tbody) to display block, is that browser synchronization of the column sizes between the various components is quickly lost and everything packs to the smallest permissible size. Setting the widths of the columns seems like the best course of action, but without setting the widths of all the internal table components to match the total of these columns, even with a fixed table layout, there is a slight divergence between the headers and body when a scroll bar is present.

The solution for me was to set all the widths, check if a scroll bar was present, and then take the scaled widths the browser had actually decided on, and copy those to the header and footer adjusting the last column width for the size of the scroll bar. Doing this provides some fluidity to the column widths. If changes to the table's width occur, most major browsers will auto-scale the tbody column widths accordingly. All that's left is to set the header and footer column widths from their respective tbody sizes.

$table.find("> thead,> tfoot").find("> tr:first-child")
    .each(function(i,e) {
        $(e).children().each(function(i,e) {
            if (i != column_scaled_widths.length - 1) {
                $(e).width(column_scaled_widths[i] - ($(e).outerWidth() - $(e).width()));
            } else {
                $(e).width(column_scaled_widths[i] - ($(e).outerWidth() - $(e).width()) + $.position.scrollbarWidth());
            }
        });
    });

This fiddle illustrates these notions: http://jsfiddle.net/borgboyone/gbkbhngq/.

Note that a table wrapper or additional tables are not needed for y-axis scrolling alone. (X-axis scrolling does require a wrapping table.) Synchronization between the column sizes for the body and header will still be lost if the minimum pack size for either the header or body columns is encountered. A mechanism for minimum widths should be provided if resizing is an option or small table widths are expected.

The ultimate culmination from this starting point is fully realized here: http://borgboyone.github.io/jquery-ui-table/

A.

an extension to Adam's answer incase you need to prevend default, here is a work around:

$(document).on('DOMNodeRemoved', function(e){
        if($(e.target).hasClass('my-elm') && !e.target.hasAttribute('is-clone')){
            let clone = $(e.target).clone();
            $(clone).attr('is-clone', ''); //allows the clone to be removed without triggering the function again

            //you can do stuff to clone here (ex: add a fade animation)

            $(clone).insertAfter(e.target);
            setTimeout(() => {
                //optional remove clone after 1 second
                $(clone).remove();
            }, 1000);
        }
    });

You can achieve this with a conditional in an angular expression, such as:

<a href="#" class="{{ condition ? 'active' : '' }}">link</a>

That being said, I do find an angular directive to be the more "proper" way of doing it, even though outsourcing a lot of this mini-logic can somewhat pollute your code base.

I use conditionals for GUI styling every once in a while during development, because it's a little quicker than creating directives. I couldn't tell you an instance though in which they actually remained in the code base for long. In the end I either turn it into a directive or find a better way to solve the problem.

PDO is the standard, it's what most developers will expect to use. mysqli was essentially a bespoke solution to a particular problem, but it has all the problems of the other DBMS-specific libraries. PDO is where all the hard work and clever thinking will go.

In case of SVN servers you have to creating a central repository with all projects. The contents of the repository can be uploaded with the Team/Share command; in case of the Subversive client it automatically runs a commit after the import, so you can upload your files.

This step cannot be circumvented in any way using a centralized version management system such as SVN.

I faced this issue once and was able to resolve it by fixing of my /etc/hosts. It just was unable to resolve localhost name... Details are here: http://itvictories.com/node/6

In fact, there is 99% that error related to /etc/hosts file

X server just unable to resolve localhost and all consequent actions just fails.

Please be sure that you have a record like

127.0.0.1 localhost

in your /etc/hosts file.

I think you mean to put the rolling of the random a,b,c, etc within the loop:

a = None # initialise
while not (a in winning_numbers):
    # keep rolling an a until you get one not in winning_numbers
    a = random.randint(1,30)
    winning_numbers.append(a)

Otherwise, a will be generated just once, and if it is in winning_numbers already, it won't be added. Since the generation of a is outside the while (in your code), if a is already in winning_numbers then too bad, it won't be re-rolled, and you'll have one less winning number.

That could be what causes your error in if guess[i] == winning_numbers[i]. (Your winning_numbers isn't always of length 5).

You could check path to qmake using which qmake.

Consider install qt4-default or qt5-default depends what version of qt you want use.

You could also use qtchooser - a wrapper used to select between Qt development binary versions.

NSDictionary -> NSData:

NSMutableData *data = [[NSMutableData alloc] init];
NSKeyedArchiver *archiver = [[NSKeyedArchiver alloc] initForWritingWithMutableData:data];
[archiver encodeObject:yourDictionary forKey:@"Some Key Value"];
[archiver finishEncoding];
[archiver release];

// Here, data holds the serialized version of your dictionary
// do what you need to do with it before you:
[data release];

NSData -> NSDictionary

NSData *data = [[NSMutableData alloc] initWithContentsOfFile:[self dataFilePath]];
NSKeyedUnarchiver *unarchiver = [[NSKeyedUnarchiver alloc] initForReadingWithData:data];
NSDictionary *myDictionary = [[unarchiver decodeObjectForKey:@"Some Key Value"] retain];
[unarchiver finishDecoding];
[unarchiver release];
[data release];

You can do that with any class that conforms to NSCoding.

I had the same error when initializing Spring on startup, using some different library versions, but everything worked when I got my versions in this order in the classpath (the other libraries in the cp were not important):

1. asm-3.1.jar
2. cglib-nodep-2.1_3.jar
3. asm-attrs-1.5.3.jar

console.log(document.getElementById('xx') ) evaluates to null.

document.getElementById('xx') !=null evaluates to false

You should use document.getElementById('xx') !== null as it is a stronger equality check.

In ExtJs, you can use

xtype: 'image'

to render a image.

Here is a fiddle showing rendering of binary data with extjs.

atob -- > converts ascii to binary

btoa -- > converts binary to ascii

Ext.application({
    name: 'Fiddle',

    launch: function () {
        var srcBase64 = "data:image/jpeg;base64," + btoa(atob("iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAYAAAAfFcSJAAAADUlEQVR42mP8H8hYDwAFegHS8+X7mgAAAABJRU5ErkJggg=="));

        Ext.create("Ext.panel.Panel", {
            title: "Test",
            renderTo: Ext.getBody(),
            height: 400,
            items: [{
                xtype: 'image',
                width: 100,
                height: 100,
                src: srcBase64
            }]
        })
    }
});

All you need to do is include the boostrap css within your index.html file.

In my case, this was caused by creating a SVN patch file that encompassed the addition of the font files. Like so:

1. Add font files from local file system to subversioned trunk
2. Trunk works as expected
3. Create SVN patch of trunk changes, to include addition of font files
4. Apply patch to another branch
5. Font files are added to subversioned branch (and can be committed), but are corrupted, yielding error in OP.

The solution was to upload the font files directly into the branch from my local file system. I assume this happened because SVN patch files must convert everything to ASCII format, and don't necessarily retain binary for font files. But that's only a guess.

If your server is Ubuntu and Apache version is 2.4

Server version: Apache/2.4.29 (Ubuntu)

Then you export variables in "/etc/apache2/envvars" location.

Just like this below line, you need to add an extra line in "/etc/apache2/envvars" export GOROOT=/usr/local/go

.container {_x000D_
  background: tomato;_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
  align-content: space-between;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
_x000D_
.item {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  background: gold;_x000D_
  border: 1px solid black;_x000D_
  font-size: 30px;_x000D_
  line-height: 100px;_x000D_
  text-align: center;_x000D_
  margin: 10px;_x000D_
}

<div class="container">_x000D_
  <div>_x000D_
    <div class="item">1</div>_x000D_
    <div class="item">2</div>_x000D_
    <div class="item">3</div>_x000D_

    <div class="item">9</div>_x000D_
  </div>_x000D_
  <div class="item">10</div>_x000D_
</div>

you could try wrapping the items in a dom element like here. with this you dont have to know a lot of css just having a good structure will solve the problem.

I have 2 tables like this:

> SELECT * FROM table_a;
+------+------+
| id   | name |
+------+------+
|    1 | row1 |
|    2 | row2 |
+------+------+

> SELECT * FROM table_b;
+------+------+------+
| id   | name | aid  |
+------+------+------+
|    3 | row3 |    1 |
|    4 | row4 |    1 |
|    5 | row5 | NULL |
+------+------+------+

INNER JOIN cares about both tables

INNER JOIN cares about both tables, so you only get a row if both tables have one. If there is more than one matching pair, you get multiple rows.

> SELECT * FROM table_a a INNER JOIN table_b b ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | id   | name | aid  |
+------+------+------+------+------+
|    1 | row1 |    3 | row3 | 1    |
|    1 | row1 |    4 | row4 | 1    |
+------+------+------+------+------+

It makes no difference to INNER JOIN if you reverse the order, because it cares about both tables:

> SELECT * FROM table_b b INNER JOIN table_a a ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | aid  | id   | name |
+------+------+------+------+------+
|    3 | row3 | 1    |    1 | row1 |
|    4 | row4 | 1    |    1 | row1 |
+------+------+------+------+------+

You get the same rows, but the columns are in a different order because we mentioned the tables in a different order.

LEFT JOIN only cares about the first table

LEFT JOIN cares about the first table you give it, and doesn't care much about the second, so you always get the rows from the first table, even if there is no corresponding row in the second:

> SELECT * FROM table_a a LEFT JOIN table_b b ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | id   | name | aid  |
+------+------+------+------+------+
|    1 | row1 |    3 | row3 | 1    |
|    1 | row1 |    4 | row4 | 1    |
|    2 | row2 | NULL | NULL | NULL |
+------+------+------+------+------+

Above you can see all rows of table_a even though some of them do not match with anything in table b, but not all rows of table_b - only ones that match something in table_a.

If we reverse the order of the tables, LEFT JOIN behaves differently:

> SELECT * FROM table_b b LEFT JOIN table_a a ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | aid  | id   | name |
+------+------+------+------+------+
|    3 | row3 | 1    |    1 | row1 |
|    4 | row4 | 1    |    1 | row1 |
|    5 | row5 | NULL | NULL | NULL |
+------+------+------+------+------+

Now we get all rows of table_b, but only matching rows of table_a.

RIGHT JOIN only cares about the second table

a RIGHT JOIN b gets you exactly the same rows as b LEFT JOIN a. The only difference is the default order of the columns.

> SELECT * FROM table_a a RIGHT JOIN table_b b ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | id   | name | aid  |
+------+------+------+------+------+
|    1 | row1 |    3 | row3 | 1    |
|    1 | row1 |    4 | row4 | 1    |
| NULL | NULL |    5 | row5 | NULL |
+------+------+------+------+------+

This is the same rows as table_b LEFT JOIN table_a, which we saw in the LEFT JOIN section.

Similarly:

> SELECT * FROM table_b b RIGHT JOIN table_a a ON a.id=b.aid;
+------+------+------+------+------+
| id   | name | aid  | id   | name |
+------+------+------+------+------+
|    3 | row3 | 1    |    1 | row1 |
|    4 | row4 | 1    |    1 | row1 |
| NULL | NULL | NULL |    2 | row2 |
+------+------+------+------+------+

Is the same rows as table_a LEFT JOIN table_b.

No join at all gives you copies of everything

If you write your tables with no JOIN clause at all, just separated by commas, you get every row of the first table written next to every row of the second table, in every possible combination:

> SELECT * FROM table_b b, table_a;
+------+------+------+------+------+
| id   | name | aid  | id   | name |
+------+------+------+------+------+
|    3 | row3 | 1    |    1 | row1 |
|    3 | row3 | 1    |    2 | row2 |
|    4 | row4 | 1    |    1 | row1 |
|    4 | row4 | 1    |    2 | row2 |
|    5 | row5 | NULL |    1 | row1 |
|    5 | row5 | NULL |    2 | row2 |
+------+------+------+------+------+

(This is from my blog post Examples of SQL join types)

One is an alias for the other.

In Java 8 you can use

1) Stream API :

String[] a = new String[] {"a", "b", "c"};
String result = Arrays.stream(a).collect(Collectors.joining(", "));

2) new String.join method: https://stackoverflow.com/a/21756398/466677

3) java.util.StringJoiner class: http://docs.oracle.com/javase/8/docs/api/java/util/StringJoiner.html

Normally when querying a database with SQL and then fill a data-table with its results, it will never be a null Data table. You have the column headers filled with column information even if you returned 0 records.When one tried to process a data table with 0 records but with column information it will throw exception.To check the datatable before processing one could check like this.

if (DetailTable != null && DetailTable.Rows.Count>0)

Use:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= TRUNC(SYSDATE) - 30

SYSDATE returns the date & time; TRUNC resets the date to being as of midnight so you can omit it if you want the creation_date that is 30 days previous including the current time.

Depending on your needs, you could also look at using ADD_MONTHS:

SELECT *
  FROM YOUR_TABLE
 WHERE creation_date <= ADD_MONTHS(TRUNC(SYSDATE), -1)

I guess the below should work (instead of the writer part from your example). I'm unfortunately with no build environment so It's from memory but I hope it helps

using (var fs = File.Open(filePath, FileMode.Open, FileAccess.ReadWrite)))
        {
            var destinationReader = StreamReader(fs);
            var writer = StreamWriter(fs);
            while ((line = reader.ReadLine()) != null)
            {
              if (line_number == line_to_edit)
                {
                    writer.WriteLine(lineToWrite);
                }
                else
                {
                    destinationReader .ReadLine();
                }
                line_number++;
            }
        }

This happens because you trying to run service at the same port and there is an already running application.

This can happen because your service is not stopped in the process stack. Then you just have to kill this process.

There is no need to install anything here is the one line command to kill all running python processes.

for Linux based OS:

Bash:

kill -9 $(ps -A | grep python | awk '{print $1}')

Fish:

kill -9 (ps -A | grep python | awk '{print $1}')

The problem lays here:

--This result set has 3 columns
select LOC_id,LOC_locatie,LOC_deelVan_LOC_id from tblLocatie t
where t.LOC_id = 1 -- 1 represents an example

union all

--This result set has 1 columns   
select t.LOC_locatie + '>' from tblLocatie t
inner join q parent on parent.LOC_id = t.LOC_deelVan_LOC_id

In order to use union or union all number of columns and their types should be identical cross all result sets.

I guess you should just add the column LOC_deelVan_LOC_id to your second result set

This will do it

<input id="button" type="submit" name="button" onclick="myFunction();" value="enter"/>

<script>
function myFunction(){
    alert("You button was pressed");
};   
</script>

If the setTimeout function does not work for you either, then do the following:

//Create an iframe
iframe = $('body').append($('<iframe id="documentToPrint" name="documentToPrint" src="about:blank"/>'));
iframeElement = $('#documentToPrint')[0].contentWindow.document;

//Open the iframe
iframeElement.open();

//Write your content to the iframe
iframeElement.write($("yourContentId").html());

//This is the important bit.
//Wait for the iframe window to load, then print it.
$('#documentToPrint')[0].contentWindow.onload = function () {
    $('#print-document')[0].contentWindow.print();
    $('#print-document').remove();
};
iframeElement.close();

You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.

mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )

mysql $link generally means, the resource object of the established mysqli connection to query the database.

So there are two ways of solving this problem

mysqli_query();

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql"); 
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));

Or, Using mysql_query() (This is now obselete)

$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");        
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());

As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .

You should be able to use something like this, it has worked okay for me:

var valuesToMatch = yourList.Where(stringCheck => stringCheck.Contains(myString));

or something like this, if you need to look where it doesn't match.

 var valuesToMatch = yourList.Where(stringCheck => !stringCheck.Contains(myString));

to add an anomymous function to do that may be an alternative:

<div v-on:click="return function() { fn1('foo');fn2('bar'); }()"> </div> 

Use that Code

 $('#button').submit(function(e) {
    e.preventDefault();
    // Coding
    $('#IDModal').modal('toggle'); //or  $('#IDModal').modal('hide');
    return false;
});

I was having the same problem until I read Jon Skeet's answer about the debugger displaying a single backslash with a double backslash even though the string may have a single backslash. I was not aware of that. So I changed my code from

text2 = text1.Replace(@"\\", @"/");

to

text2 = text1.Replace(@"\", @"/");

and that solved the problem. Note: I'm interfacing and R.Net which uses single forward slashes in path strings.

I didn't see how to add parameters to the method call, it took me a while to find it, so I add it here. How to pass parameters in (to the javascript function), use "arguments[0]" as the parameter place and then set the parameter as input parameter in the executeScript function.

    driver.executeScript("function(arguments[0]);","parameter to send in");

You can disable it with -Wno-reorder.

You have to give a name attribute on your <select /> element, and then use it from the $_POST or $_GET (depending on how you transmit data) arrays in PHP. Be sure to sanitize user input, though.

The JLabel background is transparent by default. Set the opacity at true like that:

label.setOpaque(true);

The only way to project a collection that is not linear time is to do so lazily, where the resulting "vector" is actually a subtype which delegates to the original collection. For example, Scala's List#subseq method create a sub-sequence in constant time. However, this only works if the collection is immutable and if the underlying language sports garbage collection.

Omar's solution is decent* if you cannot upgrade your environment to .NET 4.5 in order to gain access to the async and await APIs. That said, there here is one important change that should be made in order to avoid poor performance. A slight delay should be added between calls to Application.DoEvents() in order to prevent excessive CPU usage. By adding

Thread.Sleep(1);

before the call to Application.DoEvents(), you can add such a delay (1 millisecond) and prevent the application from using all of the cpu cycles available to it.

private void WaitNSeconds(int seconds)
{
    if (seconds < 1) return;
    DateTime _desired = DateTime.Now.AddSeconds(seconds);
    while (DateTime.Now < _desired) {
         Thread.Sleep(1);
         System.Windows.Forms.Application.DoEvents();
    }
}

*See https://blog.codinghorror.com/is-doevents-evil/ for a more detailed discussion on the potential pitfalls of using Application.DoEvents().

You can change your target's launch settings in "Manage Scheme" to Wait for <app>.app to be launched manually, which allows you debug by setting a breakpoint in application: didReceiveRemoteNotification: fetchCompletionHandler: and sending the push notification to trigger the background launch.

I'm not sure it'll solve the issue, but it may assist you with debugging for now.

Try this first, you may be passing a Null Model:

@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
    <label for="Image">Change picture</label>
}
else
{ 
    <label for="Image">Add picture</label>
}

Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.

<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>

A True or False version, based on @DMfll answer:

try:
    # python2
    from urlparse import urlparse
except:
    # python3
    from urllib.parse import urlparse

a = 'http://www.cwi.nl:80/%7Eguido/Python.html'
b = '/data/Python.html'
c = 532
d = u'dkakasdkjdjakdjadjfalskdjfalk'

def uri_validator(x):
    try:
        result = urlparse(x)
        return all([result.scheme, result.netloc, result.path])
    except:
        return False

print(uri_validator(a))
print(uri_validator(b))
print(uri_validator(c))
print(uri_validator(d))

Gives:

True
False
False
False

?: is a short-hand condition for else {} and if(){} problems. So your code is interchangeable to this:

if(max != 0){
       hsb.s = 225 * delta / max
}
else {
       hsb.s = 0
}

MDN - Conditional (Ternary) Operator

If you want to split a string into more than two columns based on a delimiter you can omit the 'maximum splits' parameter.
You can use:

df['column_name'].str.split('/', expand=True)

This will automatically create as many columns as the maximum number of fields included in any of your initial strings.

First off, you need to get a MemberInfo object that represents that property. You will need to do some form of reflection:

MemberInfo property = typeof(Class1).GetProperty("Name");

(I'm using "old-style" reflection, but you can also use an expression tree if you have access to the type at compile-time)

Then you can fetch the attribute and obtain the value of the DisplayName property:

var attribute = property.GetCustomAttributes(typeof(DisplayNameAttribute), true)
      .Cast<DisplayNameAttribute>().Single();
string displayName = attribute.DisplayName;

() parentheses are required typo error

string[] tokens = str.Split(new[] { "is Marco and" }, StringSplitOptions.None);

If you have a single character delimiter (like for instance ,), you can reduce that to (note the single quotes):

string[] tokens = str.Split(',');

If you're ever dynamically generating page content or loading content through AJAX, the following example is really the way you should go:

1. It prevents double binding in the case where the script is loaded more than once, such as in an AJAX request.
2. The bind lives on the body of the document, so regardless of what elements are added, moved, removed and re-added, all descendants of body matching the selector specified will retain proper binding.

The Code:

// Define the element we wish to bind to.
var bind_to = ':input';

// Prevent double-binding.
$(document.body).off('change', bind_to);

// Bind the event to all body descendants matching the "bind_to" selector.
$(document.body).on('change keyup', bind_to, function(event) {
    alert('something happened!');
});

Please notice! I'm making use of $.on() and $.off() rather than other methods for several reasons:

1. $.live() and $.die() are deprecated and have been omitted from more recent versions of jQuery.
2. I'd either need to define a separate function (therefore cluttering up the global scope,) and pass the function to both $.change() and $.keyup() separately, or pass the same function declaration to each function called; Duplicating logic... Which is absolutely unacceptable.
3. If elements are ever added to the DOM, $.bind() does not dynamically bind to elements as they are created. Therefore if you bind to :input and then add an input to the DOM, that bind method is not attached to the new input. You'd then need to explicitly un-bind and then re-bind to all elements in the DOM (otherwise you'll end up with binds being duplicated). This process would need to be repeated each time an input was added to the DOM.

SELECT * FROM yourtable WHERE yourtimestampfield LIKE 'AAAA-MM%';

Where AAAA is the year you want and MM is the month you want

Does it have to be String.Format?

This looks like a job for String.Padleft

myString=myString.PadLeft(3, '0');

Or, if you are converting direct from an int:

myInt.toString("D3");

This might solve your problem.

after doing changes you can commit it and then

git remote add origin https://(address of your repo) it can be https or ssh
then
git push -u origin master

hope it works for you.

thanks

You may also write it like

{ this.state.banner && <div>{...}</div> }

If your state.banner is null or undefined, the right side of the condition is skipped.

The MySQL Administrator (part of the MySQL GUI Tools) can do that for you on a database level.

Just select your schema and press the Maintenance button in the bottom right corner.

Since the GUI Tools have reached End-of-life status they are hard to find on the mysql page. Found them via Google: http://dev.mysql.com/downloads/gui-tools/5.0.html

I don't know if the new MySQL Workbench can do that, too.

And you can use the mysqlcheck command line tool which should be able to do that, too.

Here's one way:

cout << '\a';

From C++ Character Constants:

Alert: \a

Here is my code, hope this will help you !

 public boolean isDigitOnly(String text){

    boolean isDigit = false;

    if (text.matches("[0-9]+") && text.length() > 2) {
        isDigit = true;
    }else {
        isDigit = false;
    }

    return isDigit;
}

For Android API level 13 and you need to use this:

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int maxX = size.x; 
int maxY = size.y;

Then (0,0) is top left corner and (maxX,maxY) is bottom right corner of the screen.

The 'getWidth()' for screen size is deprecated since API 13

Furthermore getwidth() and getHeight() are methods of android.view.View class in android.So when your java class extends View class there is no windowManager overheads.

          int maxX=getwidht();
          int maxY=getHeight();

as simple as that.

Gold Noise

This function has improved random distribution over the current function in @appas' answer as of Sept 9, 2017:

The @appas function is also incomplete, given there is no seed supplied (uv is not a seed - same for every frame), and does not work with low precision chipsets. Gold Noise runs at low precision by default (much faster).

if you use recompose, use mapProps to make new props derived from incoming props

Edit for example:

import { compose, mapProps } from 'recompose';

const SomeComponent = ({ url, onComplete }) => (
  {url ? (
    <View />
  ) : null}
)

export default compose(
  mapProps(({ url, storeUrl, history, ...props }) => ({
    ...props,
    onClose: () => {
      history.goBack();
    },
    url: url || storeUrl,
  })),
)(SomeComponent);

If these are elements naturally in the tab order like buttons and anchors, removing them from the tab order with tabindex="-1" is kind of an accessibility smell. If they're providing duplicate functionality removing them from the tab order is ok, and consider adding aria-hidden="true" to these elements so assistive technologies will ignore them.

I had this issue also and I simply found out that if you simply remove the "#" the issue goes off. Like this :

<a href="" class="disabled" ng-click="doSomething(object)">Do something</a>

I would like to expand on Riki_tiki_tavi's answer and get the data out there. I have created a datediff function that does almost everything sql server does. So that way we can take into account any unit.

create function datediff(units character varying, start_t timestamp without time zone, end_t timestamp without time zone) returns integer
language plpgsql
 as
 $$
DECLARE
 diff_interval INTERVAL; 
 diff INT = 0;
 years_diff INT = 0;
BEGIN
 IF units IN ('yy', 'yyyy', 'year', 'mm', 'm', 'month') THEN
   years_diff = DATE_PART('year', end_t) - DATE_PART('year', start_t);

   IF units IN ('yy', 'yyyy', 'year') THEN
     -- SQL Server does not count full years passed (only difference between year parts)
     RETURN years_diff;
   ELSE
     -- If end month is less than start month it will subtracted
     RETURN years_diff * 12 + (DATE_PART('month', end_t) - DATE_PART('month', start_t)); 
   END IF;
 END IF;

 -- Minus operator returns interval 'DDD days HH:MI:SS'  
 diff_interval = end_t - start_t;

 diff = diff + DATE_PART('day', diff_interval);

 IF units IN ('wk', 'ww', 'week') THEN
   diff = diff/7;
   RETURN diff;
 END IF;

 IF units IN ('dd', 'd', 'day') THEN
   RETURN diff;
 END IF;

 diff = diff * 24 + DATE_PART('hour', diff_interval); 

 IF units IN ('hh', 'hour') THEN
    RETURN diff;
 END IF;

 diff = diff * 60 + DATE_PART('minute', diff_interval);

 IF units IN ('mi', 'n', 'minute') THEN
    RETURN diff;
 END IF;

 diff = diff * 60 + DATE_PART('second', diff_interval);

 RETURN diff;
END;
$$;

You need to use the new operator when creating the object

Contacts.add(new Data(name, address, contact)); // Creating a new object and adding it to list - single step

or else

Data objt = new Data(name, address, contact); // Creating a new object
Contacts.add(objt); // Adding it to the list

and your constructor shouldn't contain void. Else it becomes a method in your class.

public Data(String n, String a, String c) { // Constructor has the same name as the class and no return type as such

   strScriptFullname = WScript.ScriptFullName 
   strScriptPath = Left(strScriptFullname, InStrRev(strScriptFullname,"\")) 

Use the id selector #

$('#passwordsNoMatchRegister').show();

I needed a solution that doesn't require changes to controllers, because for some pages we only render templates and there's no controller at all. Thanks to previous commenters who suggested using $routeChangeSuccess I came up with something like this:

# Directive
angular.module('myapp.directives')
.directive 'ActiveTab', ($route) ->
  restrict: 'A'

  link: (scope, element, attrs) ->
    klass = "active"

    if $route.current.activeTab? and attrs.flActiveLink is $route.current.activeTab
      element.addClass(klass)

    scope.$on '$routeChangeSuccess', (event, current) ->
      if current.activeTab? and attrs.flActiveLink is current.activeTab
        element.addClass(klass)
      else
        element.removeClass(klass)

# Routing
$routeProvider
.when "/page",
  templateUrl: "page.html"
  activeTab: "page"
.when "/other_page",
  templateUrl: "other_page.html"
  controller: "OtherPageCtrl"
  activeTab: "other_page"

# View (.jade)
a(ng-href='/page', active-tab='page') Page
a(ng-href='/other_page', active-tab='other_page') Other page

It doesn't depend on URLs and thus it's really easy to set it up for any sub pages etc.

Autolayout just like UILabel, with the link detection, text selection, editing and scrolling of UITextView.

Automatically handles

• Safe area
• Content insets
• Line fragment padding
• Text container insets
• Constraints
• Stack views
• Attributed strings
• Whatever.

A lot of these answers got me 90% there, but none were fool-proof.

Drop in this UITextView subclass and you're good.

The NSDictionary and NSMutableDictionary docs are probably your best bet. They even have some great examples on how to do various things, like...

...create an NSDictionary

NSArray *keys = [NSArray arrayWithObjects:@"key1", @"key2", nil];
NSArray *objects = [NSArray arrayWithObjects:@"value1", @"value2", nil];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects 
                                                       forKeys:keys];

...iterate over it

for (id key in dictionary) {
    NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]);
}

...make it mutable

NSMutableDictionary *mutableDict = [dictionary mutableCopy];

Note: historic version before 2010: [[dictionary mutableCopy] autorelease]

...and alter it

[mutableDict setObject:@"value3" forKey:@"key3"];

...then store it to a file

[mutableDict writeToFile:@"path/to/file" atomically:YES];

...and read it back again

NSMutableDictionary *anotherDict = [NSMutableDictionary dictionaryWithContentsOfFile:@"path/to/file"];

...read a value

NSString *x = [anotherDict objectForKey:@"key1"];

...check if a key exists

if ( [anotherDict objectForKey:@"key999"] == nil ) NSLog(@"that key is not there");

...use scary futuristic syntax

From 2014 you can actually just type dict[@"key"] rather than [dict objectForKey:@"key"]

Make sure you have set database engine to InnoDB because in MyISAM foreign key and transaction are not supported

Timings on Excel 2013 fairly slow machine with a big bad used range million rows:

26ms Cells.Find xlPrevious method (as above)

0.4ms Sheet.UsedRange (just call it)

0.14ms Counta binary search + 0.4ms Used Range to start search (12 CountA calls)

So the Find xlPrevious is quite slow if that is of concern.

The CountA binary search approach is to first do a Used Range. Then chop the range in half and see if there are any non-empty cells in the bottom half, and then halve again as needed. It is tricky to get right.

If the concrete methods invoke any of the abstract methods that strategy won't work, and you'd want to test each child class behavior separately. Otherwise, extending it and stubbing the abstract methods as you've described should be fine, again provided the abstract class concrete methods are decoupled from child classes.

The Why

java.util.logging has a root logger that defaults to Level.INFO, and a ConsoleHandler attached to it that also defaults to Level.INFO. FINE is lower than INFO, so fine messages are not displayed by default.

Solution 1

Create a logger for your whole application, e.g. from your package name or use Logger.getGlobal(), and hook your own ConsoleLogger to it. Then either ask root logger to shut up (to avoid duplicate output of higher level messages), or ask your logger to not forward logs to root.

public static final Logger applog = Logger.getGlobal();
...

// Create and set handler
Handler systemOut = new ConsoleHandler();
systemOut.setLevel( Level.ALL );
applog.addHandler( systemOut );
applog.setLevel( Level.ALL );

// Prevent logs from processed by default Console handler.
applog.setUseParentHandlers( false ); // Solution 1
Logger.getLogger("").setLevel( Level.OFF ); // Solution 2

Solution 2

Alternatively, you may lower the root logger's bar.

You can set them by code:

Logger rootLog = Logger.getLogger("");
rootLog.setLevel( Level.FINE );
rootLog.getHandlers()[0].setLevel( Level.FINE ); // Default console handler

Or with logging configuration file, if you are using it:

.level = FINE
java.util.logging.ConsoleHandler.level = FINE

By lowering the global level, you may start seeing messages from core libraries, such as from some Swing or JavaFX components. In this case you may set a Filter on the root logger to filter out messages not from your program.

EnvInject Plugin aka (Environment Injector Plugin) gives you several options to set environment variables from Jenkins configuration.

By selecting Inject environment variables to the build process you will get:

• Properties File Path
• Properties Content

• Script File Path

• Script Content

• and finally Evaluated Groovy script.

Evaluated Groovy script gives you possibility to set environment variable based on result of executed command:

• with execute method:

    return [HOSTNAME_SHELL: 'hostname'.execute().text, 
        DATE_SHELL: 'date'.execute().text,
        ECHO_SHELL: 'echo hello world!'.execute().text
    ]

• or with explicit Groovy code:

    return [HOSTNAME_GROOVY: java.net.InetAddress.getLocalHost().getHostName(),
        DATE_GROOVY: new Date()
    ] 

(More details about each method could be found in build-in help (?))

Unfortunately you can't do the same from Script Content as it states:

Execute a script file aimed at setting an environment such as creating folders, copying files, and so on. Give the script file content. You can use the above properties variables. However, adding or overriding environment variables in the script doesn't have any impacts in the build job.

Yes include the first file into the second. That's all.

See an example below,

File1.php :

<?php
  function first($int, $string){ //function parameters, two variables.
    return $string;  //returns the second argument passed into the function
  }
?>

Now Using include (http://php.net/include) to include the File1.php to make its content available for use in the second file:

File2.php :

<?php
  include 'File1.php';
  echo first(1,"omg lol"); //returns omg lol;
?>

Many people still visit this so here's a very simple diagram to explain it

It's actually something that can be done using a combination of the current stack-trace data, and reflection.

public void MyMethod()
{
     StackTrace stackTrace = new System.Diagnostics.StackTrace();
     StackFrame frame = stackTrace.GetFrames()[1];
     MethodInfo method = frame.GetMethod();
     string methodName = method.Name;
     Type methodsClass = method.DeclaringType;
}

The 1 index on the StackFrame array will give you the method which called MyMethod

Just my couple cents... sometimes it's good to be sure there are no any duplicates... so we have the next function in the utils library:

jQuery.loadCSS = function(url) {
    if (!$('link[href="' + url + '"]').length)
        $('head').append('<link rel="stylesheet" type="text/css" href="' + url + '">');
}

How to use:

$.loadCSS('css/style2.css');

I resolved the same problem by this:

git config http.postBuffer 524288000

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

Cheers!

You can actually provide implementations of pure virtual functions in C++. The only difference is all pure virtual functions must be implemented by derived classes before the class can be instantiated.

My answer is basically just a polished, fully-validated, and fully-packaged, version of @AlixAxel's answer:

<?php

/* Get the 'best known' client IP. */

if (!function_exists('getClientIP'))
    {
        function getClientIP()
            {
                if (isset($_SERVER["HTTP_CF_CONNECTING_IP"])) 
                    {
                        $_SERVER['REMOTE_ADDR'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
                    };

                foreach (array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR') as $key)
                    {
                        if (array_key_exists($key, $_SERVER)) 
                            {
                                foreach (explode(',', $_SERVER[$key]) as $ip)
                                    {
                                        $ip = trim($ip);

                                        if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) !== false)
                                            {
                                                return $ip;
                                            };
                                    };
                            };
                    };

                return false;
            };
    };

$best_known_ip = getClientIP();

if(!empty($best_known_ip))
    {
        $ip = $clients_ip = $client_ip = $client_IP = $best_known_ip;
    }
else
    {
        $ip = $clients_ip = $client_ip = $client_IP = $best_known_ip = '';
    };

?>

Changes:

• It simplifies the function name (with 'camelCase' formatting style).

• It includes a check to make sure the function isn't already declared in another part of your code.

• It takes into account 'CloudFlare' compatibility.

• It initializes multiple "IP-related" variable names to the returned value, of the 'getClientIP' function.

• It ensures that if the function doesn't return a valid IP address, all the variables are set to a empty string, instead of null.

• It's only (45) lines of code.

For Swift 4.2 and above

let supportEmail = "[email protected]"
if let emailURL = URL(string: "mailto:\(supportEmail)"), UIApplication.shared.canOpenURL(emailURL)
{
    UIApplication.shared.open(emailURL, options: [:], completionHandler: nil)
}

Give the user to choose many mail options(like iCloud, google, yahoo, Outlook.com - if no mail is pre-configured in his phone) to send email.

Use MySQL Workbench. create SQL dump file of your database

Follow below steps:

1. Click File->Import->Reverse Engineer MySQL Create Script
2. Click Browse and select your SQL create script.
3. Make Sure "Place Imported Objects on a diagram" is checked.
4. Click Execute Button.
5. You are done.

To do this efficiently using jQuery, you can chain it like so:

$('.theClassThatsThereNow').addClass('newClassWithYourStyles').removeClass('theClassThatsTherenow');

For simplicities sake, you can also do it step by step like so (note assigning the jquery object to a var isnt necessary, but it feels safer in case you accidentally remove the class you're targeting before adding the new class and are directly accessing the dom node via its jquery selector like $('.theClassThatsThereNow')):

var el = $('.theClassThatsThereNow');
el.addClass('newClassWithYourStyles');
el.removeClass('theClassThatsThereNow');

Also (since there is a js tag), if you wanted to do it in vanilla js:

For modern browsers (See this to see which browsers I'm calling modern)

(assuming one element with class theClassThatsThereNow)

var el = document.querySelector('.theClassThatsThereNow');
el.classList.remove('theClassThatsThereNow');
el.classList.add('newClassWithYourStyleRules');

Or older browsers:

var el = document.getElementsByClassName('theClassThatsThereNow');
el.className = el.className.replace(/\s*theClassThatsThereNow\s*/, ' newClassWithYourStyleRules ');

There is no draft requirement for JS to use a specific sorting algorthim. As many have mentioned here, Mozilla uses merge sort.However, In Chrome's v8 source code, as of today, it uses QuickSort and InsertionSort, for smaller arrays.

V8 Engine Source

From Lines 807 - 891

  var QuickSort = function QuickSort(a, from, to) {
    var third_index = 0;
    while (true) {
      // Insertion sort is faster for short arrays.
      if (to - from <= 10) {
        InsertionSort(a, from, to);
        return;
      }
      if (to - from > 1000) {
        third_index = GetThirdIndex(a, from, to);
      } else {
        third_index = from + ((to - from) >> 1);
      }
      // Find a pivot as the median of first, last and middle element.
      var v0 = a[from];
      var v1 = a[to - 1];
      var v2 = a[third_index];

Update As of 2018 V8 uses TimSort, thanks @celwell. Source

some resources:

1. ELF for the ARM architecture
   http://infocenter.arm.com/help/topic/com.arm.doc.ihi0044d/IHI0044D_aaelf.pdf
2. ELF from wiki
   http://en.wikipedia.org/wiki/Executable_and_Linkable_Format

ELF format is generally the default output of compiling. if you use GNU tool chains, you can translate it to binary format by using objcopy, such as:

  arm-elf-objcopy -O binary [elf-input-file] [binary-output-file]

or using fromELF utility(built in most IDEs such as ADS though):

 fromelf -bin -o [binary-output-file] [elf-input-file]

If we use msvc or Qt (up to Qt 4.5), since GCC(up to 3.4) , msvc both support #pragma once, I can see no reason for not using #pragma once.

Source file name usually same equal class name, and we know, sometime we need refactor, to rename class name, then we had to change the #include XXXX also, so I think manual maintain the #include xxxxx is not a smart work. even with Visual Assist X extension, maintain the "xxxx" is not a necessary work.

This only worked right for me when including strip.white = TRUE in the read.csv command.

(I found the solution here.)

Error in your question is raised when you try something like following:

>>> a_dictionary = {}
>>> a_dictionary.update([[1]])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: dictionary update sequence element #0 has length 1; 2 is required

It's hard to tell where is the cause in your code unless you show your code, full traceback.

Assuming you want to get columns 1 and 9 with that code snippet, it should be:

extractedData = data[:,[1,9]]

The Uri class is generally your best bet for manipulating Urls.

Cookies and Sessions are used to store information. Cookies are only stored on the client-side machine, while sessions get stored on the client as well as a server.

Session

A session creates a file in a temporary directory on the server where registered session variables and their values are stored. This data will be available to all pages on the site during that visit.

A session ends when the user closes the browser or after leaving the site, the server will terminate the session after a predetermined period of time, commonly 30 minutes duration.

Cookies

Cookies are text files stored on the client computer and they are kept of use tracking purposes. The server script sends a set of cookies to the browser. For example name, age, or identification number, etc. The browser stores this information on a local machine for future use.

When the next time the browser sends any request to the web server then it sends those cookies information to the server and the server uses that information to identify the user.

You can use a data: URL to embed a Base64 encoded version of an image. But it's not very efficient and wouldn't recommend embedding large images. Any reason linking to another file is not feasible?

Case: If you need to ignore the merge commit created by default, follow these steps.

Say, a new feature branch is checked out from master having 2 commits already,

• "Added A" , "Added B"

Checkout a new feature_branch

• "Added C" , "Added D"

Feature branch then adds two commits-->

• "Added E", "Added F"

Now if you want to merge feature_branch changes to master, Do git merge feature_branch sitting on the master.

This will add all commits into master branch (4 in master + 2 in feature_branch = total 6) + an extra merge commit something like 'Merge branch 'feature_branch'' as the master is diverged.

If you really need to ignore these commits (those made in FB) and add the whole changes made in feature_branch as a single commit like 'Integrated feature branch changes into master', Run git merge feature_merge --no-commit.

With --no-commit, it perform the merge and stop just before creating a merge commit, We will have all the added changes in feature branch now in master and get a chance to create a new commit as our own.

I tried the solution priyanka.sarkar mentioned and the didn't quite get it working as the OP asked. Here's the solution I ended up with:

SELECT ID, 
        SUBSTRING((
            SELECT ',' + T2.SomeColumn
            FROM  @T T2 
            WHERE WHERE T1.id = T2.id
            FOR XML PATH('')), 2, 1000000)
    FROM @T T1
GROUP BY ID

You can not use multiple router outlets in the same template with ngIf condition. But you can use it in the way shown below:

<div *ngIf="loading">
  <span>loading true</span>
  <ng-container *ngTemplateOutlet="template"></ng-container>
</div>

<div *ngIf="!loading">
  <span>loading false</span>
  <ng-container *ngTemplateOutlet="template"></ng-container>
  </div>

  <ng-template #template>
    <router-outlet> </router-outlet>
  </ng-template>

I had to use a wildcard route at the end of my routes array.

{ path: '**', redirectTo: 'home' }

And the error was resolved.

The severity level 16 in your example code is typically used for user-defined (user-detected) errors. The SQL Server DBMS itself emits severity levels (and error messages) for problems it detects, both more severe (higher numbers) and less so (lower numbers).

The state should be an integer between 0 and 255 (negative values will give an error), but the choice is basically the programmer's. It is useful to put different state values if the same error message for user-defined error will be raised in different locations, e.g. if the debugging/troubleshooting of problems will be assisted by having an extra indication of where the error occurred.

The other answers cover the most common scenario: watch the content of the frames (Developer Tools -> Network tab -> Right click on the websocket connection -> frames).

If you want to know some more informations, like which sockets are currently open/idle or be able to close them you'll find this url useful

chrome://net-internals/#sockets

For example:

HTML:

<div class="dropdown">
  <button class="btn btn-default dropdown-toggle" type="button" data-toggle="dropdown">
     <BtnCaption>Select item</BtnCaption>
     <span class="caret"></span>   
  </button>
  <ul class="dropdown-menu">
     <li><a href="#">Option 1</a></li>
     <li><a href="#">Option 2</a></li>
     <li class="disabled"><a href="#">Option 3</a></li>   
  </ul> 
</div>

I use new element BtnCaption for changing only button's text.

Paste into $(document).ready(function () {} the following text

JavaScript:

    $(".dropdown-menu li:not(.disabled) a").click(function () {
        $(this).closest(".dropdown").find(".btn BtnCaption").text($(this).text()));
    });

:not(.disabled) don't allow use the disabled menu items

The above are good suggestions, but you can get at the text value of a cell in a grid view without wrapping it in a literal or label control. You just have to know what event to wire up. In this case, use the DataBound event instead, like so:

protected void GridView1_DataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.Cells[0].Text.Contains("sometext"))
        {
            e.Row.Cells[0].Font.Bold = true;
        }
    }
}

When running a debugger, you will see the text appear in this method.

I want to add that sometimes android studio loses track of the resources file and can't build on launch. If the above answers are to no avail, try

Build => Rebuild Project

I lost many hours to this when I was a beginner at Android Studio.

This reads a line of text from standard input and prints out the characters in the line and their ASCII codes:

#include <stdio.h>

void printChars(void)
{
    unsigned char   line[80+1];
    int             i;

    // Read a text line
    if (fgets(line, 80, stdin) == NULL)
        return;

    // Print the line chars
    for (i = 0;  line[i] != '\n';  i++)
    {
        int     ch;

        ch = line[i];
        printf("'%c' %3d 0x%02X\n", ch, ch, (unsigned)ch);
    }
}

With get() method you get a collection (all data that match the query), try to use first() instead, it return only one element, like this:

$about = Page::where('page', 'about-me')->first();

I use WinMerge. It is free and works pretty well (works for files and directories).

Was having the same case today, super easy in vim or nvim, you can use gJ to join lines. For your use case, just do

99gJ

this will join all your 99 lines. You can adjust the number 99 as need according to how many lines to join. If just join 1 line, then only gJ is good enough.

First you need to start karma server with

karma start

Then, you can use grep to filter a specific test or describe block:

karma run -- --grep=testDescriptionFilter

You should use a KeyGenerator to generate the Key,

AES key lengths are 128, 192, and 256 bit depending on the cipher you want to use.

Take a look at the tutorial here

Here is the code for Password Based Encryption, this has the password being entered through System.in you can change that to use a stored password if you want.

        PBEKeySpec pbeKeySpec;
        PBEParameterSpec pbeParamSpec;
        SecretKeyFactory keyFac;

        // Salt
        byte[] salt = {
            (byte)0xc7, (byte)0x73, (byte)0x21, (byte)0x8c,
            (byte)0x7e, (byte)0xc8, (byte)0xee, (byte)0x99
        };

        // Iteration count
        int count = 20;

        // Create PBE parameter set
        pbeParamSpec = new PBEParameterSpec(salt, count);

        // Prompt user for encryption password.
        // Collect user password as char array (using the
        // "readPassword" method from above), and convert
        // it into a SecretKey object, using a PBE key
        // factory.
        System.out.print("Enter encryption password:  ");
        System.out.flush();
        pbeKeySpec = new PBEKeySpec(readPassword(System.in));
        keyFac = SecretKeyFactory.getInstance("PBEWithMD5AndDES");
        SecretKey pbeKey = keyFac.generateSecret(pbeKeySpec);

        // Create PBE Cipher
        Cipher pbeCipher = Cipher.getInstance("PBEWithMD5AndDES");

        // Initialize PBE Cipher with key and parameters
        pbeCipher.init(Cipher.ENCRYPT_MODE, pbeKey, pbeParamSpec);

        // Our cleartext
        byte[] cleartext = "This is another example".getBytes();

        // Encrypt the cleartext
        byte[] ciphertext = pbeCipher.doFinal(cleartext);

It should be mentioned that since it is entirely possible to run DLL's just as any other executable, it has long been considered a security issue. As such, there have been a number of security improvements and registry hacks (sorry no longer have ref-links) that prevents running DLL's from regular user space without extra privileges.

As a good example. I recall making these hacks, but since I no longer remember what exactly I did. I can no longer run any DLLs from normal user shell environment, even though starting various Win apps from GUI works just fine.

That said, one should definitely read "Dynamic-Link Library Security" and "Best Practices to Prevent DLL Hijacking".

You can't create variables in CSS right now. If you want this sort of functionality you will need to use a CSS preprocessor like SASS or LESS. Here are your styles as they would appear in SASS:

$Color1:#fff;
$Color2:#b00;
$Color3:#050;

h1 {
    color:$Color1;
    background:$Color2;
}

They also allow you to do other (awesome) things like nesting selectors:

#some-id {
    color:red;

    &:hover {
        cursor:pointer;
    }
}

This would compile to:

#some-id { color:red; }
#some-id:hover { cursor:pointer; }

Check out the official SASS tutorial for setup instructions and more on syntax/features. Personally I use a Visual Studio extension called Web Workbench by Mindscape for easy developing, there are a lot of plugins for other IDEs as well.

Update

As of July/August 2014, Firefox has implemented the draft spec for CSS variables, here is the syntax:

:root {
  --main-color: #06c;
  --accent-color: #006;
}
/* The rest of the CSS file */
#foo h1 {
  color: var(--main-color);
}

Using an apostrophe ’ (Unicode: \u2019) instead of a single quote ' fixed the issue without doubling the \'.

I came here looking for the query string, not how to get values from the query string.

request.query_string returns the URL parameters as raw byte string (Ref 1).

Example of using request.query_string:

from flask import Flask, request

app = Flask(__name__)

@app.route('/data', methods=['GET'])
def get_query_string():
    return request.query_string

if __name__ == '__main__':
    app.run(debug=True)

Output:

References:

1. Official API documentation on query_string

For people using ES2015 (ES6)

You can now use the Spread Syntax to concatenate arrays:

const arr1 = [0, 1, 2],
      arr2 = [3, 4, 5];

const result1 = [...arr1, ...arr2]; // -> [0, 1, 2, 3, 4, 5]

// or...

const result2 = [...arr2, ...arr1]; // -> [3, 4, 5, 0, 1, 2]

Java implementation contains utilities classes java.util.Arrays and java.util.Collections both of them contains static factory methods, examples of it and how to use :

• Arrays.asList("1","2","3")

• Collections.synchronizedList(..), Collections.emptyList(), Collections.unmodifiableList(...) (Only some examples, could check javadocs for mor methods examples https://docs.oracle.com/javase/8/docs/api/java/util/Collections.html)

Also java.lang.String class have such static factory methods:

• String.format(...), String.valueOf(..), String.copyValueOf(...)

Similar like before-mentioned solutions, but most compact:

db.row_factory = lambda C, R: { c[0]: R[i] for i, c in enumerate(C.description) }

My suggested name for this technique (including multiple top-level classes in a single source file) would be "mess". Seriously, I don't think it's a good idea - I'd use a nested type in this situation instead. Then it's still easy to predict which source file it's in. I don't believe there's an official term for this approach though.

As for whether this actually changes between implementations - I highly doubt it, but if you avoid doing it in the first place, you'll never need to care :)

Adding a FileUpload control from the code behind should work just fine, where the HasFile property should be available (for instance in your Click event).

If the properties don't appear to be available (either as a compiler error or via intellisense), you probably are referencing a different variable than you think you are.

Yes, there is a way to write to the event log you are looking for. You don't need to create a new source, just simply use the existent one, which often has the same name as the EventLog's name and also, in some cases like the event log Application, can be accessible without administrative privileges*.

*Other cases, where you cannot access it directly, are the Security EventLog, for example, which is only accessed by the operating system.

I used this code to write directly to the event log Application:

using (EventLog eventLog = new EventLog("Application")) 
{
    eventLog.Source = "Application"; 
    eventLog.WriteEntry("Log message example", EventLogEntryType.Information, 101, 1); 
}

As you can see, the EventLog source is the same as the EventLog's name. The reason of this can be found in Event Sources @ Windows Dev Center (I bolded the part which refers to source name):

Each log in the Eventlog key contains subkeys called event sources. The event source is the name of the software that logs the event. It is often the name of the application or the name of a subcomponent of the application if the application is large. You can add a maximum of 16,384 event sources to the registry.

Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".

    /// <summary>
    /// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not 
    /// let the JsonProperty control everything.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class IgnoreJsonPropertyResolver<T> : DefaultContractResolver
    {
        private Dictionary<string, string> PropertyMappings { get; set; }

        public IgnoreJsonPropertyResolver()
        {
            this.PropertyMappings = new Dictionary<string, string>();
            var properties = ReflectionHelper<T>.GetGetProperties(false)();
            foreach (var propertyInfo in properties)
            {
                var jsonProperty = AttributeHelper.GetAttribute<JsonPropertyAttribute>(propertyInfo);
                if (jsonProperty != null)
                {
                    PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
                }
            }
        }

        protected override string ResolvePropertyName(string propertyName)
        {
            string resolvedName = null;
            var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
            return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
        }
    }

Usage:

        var settings = new JsonSerializerSettings();
        settings.DateFormatString = "YYYY-MM-DD";
        settings.ContractResolver = new IgnoreJsonPropertyResolver<PlanViewModel>();
        var model = new PlanViewModel() {Amount = 100};
        var strModel = JsonConvert.SerializeObject(model,settings);

Model:

public class PlanViewModel
{

    /// <summary>
    ///     The customer is charged an amount over an interval for the subscription.
    /// </summary>
    [JsonProperty(PropertyName = "RecurringPrice")]
    public double Amount { get; set; }

    /// <summary>
    ///     Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
    ///     months or years depending on the value for interval_unit.
    /// </summary>
    public int Interval { get; set; } = 1;

    /// <summary>
    ///     Number of free trial days that can be granted when a customer is subscribed to this plan.
    /// </summary>
    public int TrialPeriod { get; set; } = 30;

    /// <summary>
    /// This indicates a one-time fee charged upfront while creating a subscription for this plan.
    /// </summary>
    [JsonProperty(PropertyName = "SetupFee")]
    public double SetupAmount { get; set; } = 0;


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "TypeId")]
    public string Type { get; set; }

    /// <summary>

    /// </summary>
    [JsonProperty(PropertyName = "BillingFrequency")]
    public string Period { get; set; }


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "PlanUseType")]
    public string Purpose { get; set; }
}
