You can find a recent servlet-api.jar in Tomcat 6 or 7 lib directory. If you don't have Tomcat on your machine, download the binary distribution of version 6 or 7 from http://tomcat.apache.org/download-70.cgi

Then use + to combine strings:

console.log("story " + name + " story");

What is the error you're getting?

$ bash file.sh
test.sh: line 8: syntax error: unexpected end of file

If you get that error, you may have bad line endings. Unix uses <LF> at the end of the file while Windows uses <CR><LF>. That <CR> character gets interpreted as a character.

You can use od -a test.sh to see the invisible characters in the file.

$ od -a test.sh
0000000    #   !   /   b   i   n   /   b   a   s   h  cr  nl   #  sp  cr
0000020   nl   w   h   i   l   e  sp   :  cr  nl   d   o  cr  nl  sp  sp
0000040   sp  sp   e   c   h   o  sp   "   P   r   e   s   s  sp   [   C
0000060    T   R   L   +   C   ]  sp   t   o  sp   s   t   o   p   "  cr
0000100   nl  sp  sp  sp  sp   s   l   e   e   p  sp   1  cr  nl   d   o
0000120    n   e  cr  nl                                                
0000124

The sp stands for space, the ht stands for tab, the cr stands for <CR> and the nl stands for <LF>. Note that all of the lines end with cr followed by a nl character.

You can also use cat -v test.sh if your cat command takes the -v parameter.

If you have dos2unix on your box, you can use that command to fix your file:

$ dos2unix test.sh

On Java 9 or later, Map.entry can be used, so long as you know that neither the key nor value will be null. If either value could legitimately be null, AbstractMap.SimpleEntry (as suggested in another answer) or AbstractMap.SimpleImmutableEntry would be the way to go.

private Map<String, AttributeType> mapConfig(Map<String, String> input, String prefix) {
   int subLength = prefix.length();
   return input.entrySet().stream().map(e -> 
      Map.entry(e.getKey().substring(subLength), AttributeType.GetByName(e.getValue())));
   }).collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
}

The best and shortest way to use the table System.exit.

System.exit(0);

The VM stops further execution and program will exit.

This is a very common question seen on Stackoverflow.

The important part here is not the command displayed in the error, but what the actual error tells you instead.

a Quick breakdown on why this error is received.

cmd.exe Being a terminal window relies on input and system Environment variables, in order to perform what you request it to do. it does NOT know the location of everything and it also does not know when to distinguish between commands or executable names which are separated by whitespace like space and tab or commands with whitespace as switch variables.

How do I fix this:

When Actual Command/executable fails

First we make sure, is the executable actually installed? If yes, continue with the rest, if not, install it first.

If you have any executable which you are attempting to run from cmd.exe then you need to tell cmd.exe where this file is located. There are 2 ways of doing this.

1. specify the full path to the file.

   "C:\My_Files\mycommand.exe"

2. Add the location of the file to your environment Variables.

Goto:
------> Control Panel-> System-> Advanced System Settings->Environment Variables

In the System Variables Window, locate path and select edit

Now simply add your path to the end of the string, seperated by a semicolon ; as:

;C:\My_Files\

Save the changes and exit. You need to make sure that ANY cmd.exe windows you had open are then closed and re-opened to allow it to re-import the environment variables. Now you should be able to run mycommand.exe from any path, within cmd.exe as the environment is aware of the path to it.

When C:\Program or Similar fails

This is a very simple error. Each string after a white space is seen as a different command in cmd.exe terminal, you simply have to enclose the entire path in double quotes in order for cmd.exe to see it as a single string, and not separate commands.

So to execute C:\Program Files\My-App\Mobile.exe simply run as:

"C:\Program Files\My-App\Mobile.exe"

Another way to accomplish this in a functional component, is to use useEffect and useFunction, like this:

import React, { useEffect } from 'react';

const App = () => {


  useEffect(() => {
    const handleEsc = (event) => {
       if (event.keyCode === 27) {
        console.log('Close')
      }
    };
    window.addEventListener('keydown', handleEsc);

    return () => {
      window.removeEventListener('keydown', handleEsc);
    };
  }, []);

  return(<p>Press ESC to console log "Close"</p>);
}

Instead of console.log, you can use useState to trigger something.

Or you can use the ItemDataBound event in the code behind.

In Laravel 5.6, you will need to set it as

  session(['variableName'=>$value]);

To retrieve it is as simple as

$variableName = session('variableName')

head -n -1 abc > newfile
tail -n 1 abc | tr -d '\n' >> newfile

Edit 2:

Here is an awk version (corrected) that doesn't accumulate a potentially huge array:

awk '{if (line) print line; line=$0} END {printf $0}' abc

EDITED

You can look into sys.tables for checking existence desired table:

IF  NOT EXISTS (SELECT * FROM sys.tables
WHERE name = N'YourTable' AND type = 'U')

BEGIN
CREATE TABLE [SchemaName].[YourTable](
    ....
    ....
    ....
) 

END

I faced a similar problem , here's the solution.

Step 1 : Double click on the server listed in Eclipse. Here It will display Server Configuration.

Step 2 : Just change the port Number like from 8080 to 8085.

Step 3 : Save the changes.

Step 4 : re-start your server.

The server will start .Hope it'll help you.

You should post a message from frame to parent, after loaded.

frame script:

$(document).ready(function() {
    window.parent.postMessage("I'm loaded", "*");
});

And listen it in parent:

function listenMessage(msg) {
    alert(msg);
}

if (window.addEventListener) {
    window.addEventListener("message", listenMessage, false);
} else {
    window.attachEvent("onmessage", listenMessage);
}

…or a shorter try:

library(XML)
library(RCurl)
library(rlist)
theurl <- getURL("https://en.wikipedia.org/wiki/Brazil_national_football_team",.opts = list(ssl.verifypeer = FALSE) )
tables <- readHTMLTable(theurl)
tables <- list.clean(tables, fun = is.null, recursive = FALSE)
n.rows <- unlist(lapply(tables, function(t) dim(t)[1]))

the picked table is the longest one on the page

tables[[which.max(n.rows)]]

If you are trying to make more than just one folder on the root of the sdcard, ex. Environment.getExternalStorageDirectory() + "/Example/Ex App/"

then instead of folder.mkdir() you would use folder.mkdirs()

I've made this mistake in the past & I took forever to figure it out.

Probably you use Microsoft SQL Server which support Common Table Expressions (CTE) (see http://msdn.microsoft.com/en-us/library/ms190766.aspx) which are very friendly for query optimization. So I suggest you my favor construction:

WITH GetNumberOfPlans(Id,NumberOfPlans) AS (
    SELECT tableA.Id, COUNT(tableC.Id)
    FROM tableC
        RIGHT OUTER JOIN tableA ON tableC.tableAId = tableA.Id
    GROUP BY tableA.Id
),GetUserInformation(Id,Name,Owner,ImageUrl,
                     CompanyImageUrl,NumberOfUsers) AS (
    SELECT tableA.Id, tableA.Name, tableB.Username AS Owner, tableB.ImageUrl,
        tableB.CompanyImageUrl,COUNT(tableD.UserId),p.NumberOfPlans
    FROM tableA
        INNER JOIN tableB ON tableB.Id = tableA.Owner
        RIGHT OUTER JOIN tableD ON tableD.tableAId = tableA.Id
    GROUP BY tableA.Name, tableB.Username, tableB.ImageUrl, tableB.CompanyImageUrl
)
SELECT u.Id,u.Name,u.Owner,u.ImageUrl,u.CompanyImageUrl
    ,u.NumberOfUsers,p.NumberOfPlans
FROM GetUserInformation AS u
    INNER JOIN GetNumberOfPlans AS p ON p.Id=u.Id

After some experiences with CTE you will be find very easy to write code using CTE and you will be happy with the performance.

First off, Daniel's answer is the correct, safe option.

For the specific case of changing from SQL_ASCII to something else, you can cheat and simply poke the pg_database catalogue to reassign the database encoding. This assumes you've already stored any non-ASCII characters in the expected encoding (or that you simply haven't used any non-ASCII characters).

Then you can do:

update pg_database set encoding = pg_char_to_encoding('UTF8') where datname = 'thedb'

This will not change the collation of the database, just how the encoded bytes are converted into characters (so now length('£123') will return 4 instead of 5). If the database uses 'C' collation, there should be no change to ordering for ASCII strings. You'll likely need to rebuild any indices containing non-ASCII characters though.

Caveat emptor. Dumping and reloading provides a way to check your database content is actually in the encoding you expect, and this doesn't. And if it turns out you did have some wrongly-encoded data in the database, rescuing is going to be difficult. So if you possibly can, dump and reinitialise.

There is a very effective way to use to clear or reset Windows Form C# controls like TextBox, ComboBox, RadioButton, CheckBox, DateTimePicker etc.

private void btnClear_Click(object sender, EventArgs e)
{
    Utilities.ClearAllControls(this);
}

internal class Utilities
{
    internal static void ClearAllControls(Control control)
    {
        foreach (Control c in control.Controls)
        {
            if (c is TextBox)
            {
                ((TextBox)c).Clear();
            }
            else if (c is ComboBox)
            {
                ((ComboBox)c).SelectedIndex = -1;
            }
            else if (c is RadioButton)
            {
                ((RadioButton)c).Checked = false;
            }
            else if (c is CheckBox)
            {
                ((CheckBox)c).Checked = false;
            }
            else if (c is DateTimePicker)
            {
                ((DateTimePicker)c).Value = DateTime.Now; // or null 
            }
        }
    }
}

To accomplish this with overall user experience in c# we can use one statement to clear them. Pretty straight forward so far, above is the code.

Not really what you need, but it can help and answser the question here depending of what you want to achieve.

You can prevent all pointer events to be sent to the input by using the CSS property : pointer-events:none It will kind of add a layer on top of the element that will prevent you to click in it ... You can also add a cursor:text to the parent element to give back the text cursor style to the input ...

Usefull, for example, when you can't modify the JS/HTML of a module.. and you can just customize it by css.

You can use Series.isin:

df = df[~df.datecolumn.isin(a)]

While the error message suggests that all() or any() can be used, they are useful only when you want to reduce the result into a single Boolean value. That is however not what you are trying to do now, which is to test the membership of every values in the Series against the external list, and keep the results intact (i.e., a Boolean Series which will then be used to slice the original DataFrame).

You can read more about this in the Gotchas.

You can use java.util.Objects as following.

public static boolean compare(String str1, String str2) {
    return Objects.equals(str1, str2);
}

You can infinitely loop easily enough via recursion.

function it_keeps_going_and_going_and_going() {
  it_keeps_going_and_going_and_going();
}

it_keeps_going_and_going_and_going()

Try

SELECT TOP 10000 * FROM table ORDER BY NEWID()

Would this give the desired results, without being too over complicated?

In addition to given answer, it's worth noting that compiler is not required to initialize constexpr variable at compile time, knowing that the difference between constexpr and static constexpr is that to use static constexpr you ensure the variable is initialized only once.

Following code demonstrates how constexpr variable is initialized multiple times (with same value though), while static constexpr is surely initialized only once.

In addition the code compares the advantage of constexpr against const in combination with static.

#include <iostream>
#include <string>
#include <cassert>
#include <sstream>

const short const_short = 0;
constexpr short constexpr_short = 0;

// print only last 3 address value numbers
const short addr_offset = 3;

// This function will print name, value and address for given parameter
void print_properties(std::string ref_name, const short* param, short offset)
{
    // determine initial size of strings
    std::string title = "value \\ address of ";
    const size_t ref_size = ref_name.size();
    const size_t title_size = title.size();
    assert(title_size > ref_size);

    // create title (resize)
    title.append(ref_name);
    title.append(" is ");
    title.append(title_size - ref_size, ' ');

    // extract last 'offset' values from address
    std::stringstream addr;
    addr << param;
    const std::string addr_str = addr.str();
    const size_t addr_size = addr_str.size();
    assert(addr_size - offset > 0);

    // print title / ref value / address at offset
    std::cout << title << *param << " " << addr_str.substr(addr_size - offset) << std::endl;
}

// here we test initialization of const variable (runtime)
void const_value(const short counter)
{
    static short temp = const_short;
    const short const_var = ++temp;
    print_properties("const", &const_var, addr_offset);

    if (counter)
        const_value(counter - 1);
}

// here we test initialization of static variable (runtime)
void static_value(const short counter)
{
    static short temp = const_short;
    static short static_var = ++temp;
    print_properties("static", &static_var, addr_offset);

    if (counter)
        static_value(counter - 1);
}

// here we test initialization of static const variable (runtime)
void static_const_value(const short counter)
{
    static short temp = const_short;
    static const short static_var = ++temp;
    print_properties("static const", &static_var, addr_offset);

    if (counter)
        static_const_value(counter - 1);
}

// here we test initialization of constexpr variable (compile time)
void constexpr_value(const short counter)
{
    constexpr short constexpr_var = constexpr_short;
    print_properties("constexpr", &constexpr_var, addr_offset);

    if (counter)
        constexpr_value(counter - 1);
}

// here we test initialization of static constexpr variable (compile time)
void static_constexpr_value(const short counter)
{
    static constexpr short static_constexpr_var = constexpr_short;
    print_properties("static constexpr", &static_constexpr_var, addr_offset);

    if (counter)
        static_constexpr_value(counter - 1);
}

// final test call this method from main()
void test_static_const()
{
    constexpr short counter = 2;

    const_value(counter);
    std::cout << std::endl;

    static_value(counter);
    std::cout << std::endl;

    static_const_value(counter);
    std::cout << std::endl;

    constexpr_value(counter);
    std::cout << std::endl;

    static_constexpr_value(counter);
    std::cout << std::endl;
}

Possible program output:

value \ address of const is               1 564
value \ address of const is               2 3D4
value \ address of const is               3 244

value \ address of static is              1 C58
value \ address of static is              1 C58
value \ address of static is              1 C58

value \ address of static const is        1 C64
value \ address of static const is        1 C64
value \ address of static const is        1 C64

value \ address of constexpr is           0 564
value \ address of constexpr is           0 3D4
value \ address of constexpr is           0 244

value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0
value \ address of static constexpr is    0 EA0

As you can see yourself constexpr is initilized multiple times (address is not the same) while static keyword ensures that initialization is performed only once.

Here's a simple and clean function that returns the file size.

long get_file_size(char *path)
{
    FILE *fp;
    long size = -1;
    /* Open file for reading */
    fp = fopen(path, "r");
    fseek(fp, 0, SEEK_END);
    size = ftell(fp); 
    fp.close();
    return 
}

There is actuly a difference between array object and JSON object. Instead of creating array object and converting it into a json object(with JSON.stringify(arr)) you can do this:

var sels = //Here is your array of SELECTs
var json = { };

for(var i = 0, l = sels.length; i < l; i++) {
  json[sels[i].id] = sels[i].value;
}

There is no need of converting it into JSON because its already a json object. To view the same use json.toSource();

My solution:

First create "<style>" tags with an ID.

<style id="YourID">
    .YourClass {background-color:red}
</style>

Then, I create a function in JavaScript like this:

document.getElementById('YourID').innerHTML = '.YourClass {background-color:blue}'

Worked like a charm for me.

The best way to do this in my opinion is to use python's itertools package.

>>>import itertools
>>>l1 = [1,2,3]
>>>l2 = [10,20,30]
>>>[l*2 for l in itertools.chain(*[l1,l2])]
[2, 4, 6, 20, 40, 60]

http://jsfiddle.net/ndKWN/1/

You can use background-size: cover;

Here is another way

timestamps.sort()
timestamps.reverse()
print(timestamps)

If you want to use dynamic variables

This won't work:

{{#each obj[key]}}
...
{{/each}}

You need to do:

{{#each (lookup obj key)}}
...
{{/each}}

see handlebars lookup helper and handlebars subexpressions.

Two other alternatives:

3. a combination of NULLIF and NVL2. You can only use this if emp_id is NOT NULL, which it is in your case:

   select nvl2(nullif(emp_id,1),'False','True') from employee;
   

4. simple CASE expression (Mt. Schneiders used a so-called searched CASE expression)

   select case emp_id when 1 then 'True' else 'False' end from employee;
   

In my opinion, the easiest way to do is adding padding to your tag.

td {
 padding: 10px 0
}

Hope this will help you! Cheer!

Everything in one line:

get-aduser -filter * -Properties memberof | select name, @{ l="GroupMembership"; e={$_.memberof  -join ";"  } } | export-csv membership.csv

Try this code:

preg_match('/[a-zA-Z]+<\/a>.$/', $lastgame, $match);
print_r($match);

Using / as a delimiter means you also need to escape it here, like so: <\/a>.

UPDATE

preg_match('/<a.*<a.*>(.*)</', $lastgame, $match);
echo'['.$match[1].']';

Might not be the best way...

As your error states, you have to define drawable attibute for the items (for some reason it is required when it comes to background definitions), so:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/red"/> <!-- pressed -->
    <item android:state_focused="true" android:drawable="@color/blue"/> <!-- focused -->
    <item android:drawable="@color/black"/> <!-- default -->
</selector>

Also note that drawable attribute doesn't accept raw color values, so you have to define the colors as resources. Create colors.xml file at res/values folder:

<?xml version="1.0" encoding="utf-8"?>
<resources>
     <color name="black">#000</color>
     <color name="blue">#00f</color>
     <color name="red">#f00</color>
</resources>

I believe all the existing answers contain the relevant information, but I would like to summarize.

The response object that is returned by requests get and post operations contains two useful attributes:

Response attributes

• response.text - Contains str with the response text.
• response.content - Contains bytes with the raw response content.

You should choose one or other of these attributes depending on the type of response you expect.

• For text-based responses (html, json, yaml, etc) you would use response.text
• For binary-based responses (jpg, png, zip, xls, etc) you would use response.content.

Writing response to file

When writing responses to file you need to use the open function with the appropriate file write mode.

• For text responses you need to use "w" - plain write mode.
• For binary responses you need to use "wb" - binary write mode.

Examples

Text request and save

# Request the HTML for this web page:
response = requests.get("https://stackoverflow.com/questions/31126596/saving-response-from-requests-to-file")
with open("response.txt", "w") as f:
    f.write(response.text)

Binary request and save

# Request the profile picture of the OP:
response = requests.get("https://i.stack.imgur.com/iysmF.jpg?s=32&g=1")
with open("response.jpg", "wb") as f:
    f.write(response.content)

Answering the original question

The original code should work by using wb and response.content:

import requests

files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("out.xls", "wb")
file.write(response.content)
file.close()

But I would go further and use the with context manager for open.

import requests

with open('1.pdf', 'rb') as file:
    files = {'f': ('1.pdf', file)}
    response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)

response.raise_for_status() # ensure we notice bad responses

with open("out.xls", "wb") as file:
    file.write(response.content)

The this-operator can simplify your life:

var Y = function(f) {
    return (function(g) {
        return g(g);
    })(function(h) {
        return function() {
            return f.apply(h(h), arguments);
        };
    });
};

Then you avoid the extra function:

var fac = Y(function(n) {
    return n == 0 ? 1 : n * this(n - 1);
});

Finally, you call fac(5).

Is is not the same as = -- Is compares the references, whilst = will compare the values.

If you're using v2 of the .Net Framework (or later), there is the IsNot operator which will do the right thing, and read more naturally.

I resolved the flicker and auto-scroll by:

webView.setFocusable(false);
webView.setFocusableInTouchMode(false);

However if it still does not work for some reason, simply make a class that extends WebView, and put this method on it:

// disable scroll on touch
  setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
      return (event.getAction() == MotionEvent.ACTION_MOVE);
    }
  });

I am suggesting to extend WebView, in order to provide more effective control, like disable/enable swipes, enable/disable touches, listeners, control transitions, animations, define settings internally so on..

Use the synaptic packet manager in order to install yacc / lex. If you are feeling more comfortable doing this on the console just do:

sudo apt-get install bison flex

There are some very nice articles on the net on how to get started with those tools. I found the article from CodeProject to be quite good and helpful (see here). But you should just try and search for "introduction to lex", there are plenty of good articles showing up.

A date-time object is not a String

The java.sql.Timestamp class has no format. Its toString method generates a String with a format.

Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.

java.time

First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.

Instant instant = mySqlDate.toInstant() ;

Lose the fraction of a second you don't want.

instant = instant.truncatedTo( ChronoUnit.Seconds );

Assign the time zone to adjust from UTC used by Instant.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );

Generate a String close to your desired output. Replace its T in the middle with a SPACE.

DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );

For a responsive design it is good to use a container having a relative layout and content (placed in container) having fixed layout as.

CSS Styles:

/*Centering element in a base container*/

.contianer-relative{ 
  position: relative;
 }

.content-center-text-absolute{ 
  position: absolute; 
  text-align: center;
  width: 100%;
  height: 0%;
  margin: auto;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  z-index: 51;
}

HTML code:

<!-- Have used ionic classes -->
<div class="row">
    <div class="col remove-padding contianer-relative"><!-- container with position relative -->
        <div class="item item-image clear-border" ><a href="#"><img ng-src="img/engg-manl.png" alt="ENGINEERING MANUAL" title="ENGINEERING MANUAL" ></a></div> <!-- Image intended to work as a background -->
        <h4 class="content-center-text-absolute white-text"><strong>ENGINEERING <br> MANUALS</strong></h4><!-- content div with position fixed -->
    </div>
    <div class="col remove-padding contianer-relative"><!-- container with position relative -->
        <div class="item item-image clear-border"><a href="#"><img ng-src="img/contract-directory.png" alt="CONTRACTOR DIRECTORY" title="CONTRACTOR DIRECTORY"></a></div><!-- Image intended to work as a background -->
        <h4 class="content-center-text-absolute white-text"><strong>CONTRACTOR <br> DIRECTORY</strong></h4><!-- content div with position fixed -->
    </div>       
</div>

For IONIC Grid layout, evenly spaced grid elements and the classes used in above HTML, please refer - Grid: Evenly Spaced Columns. Hope it helps you out... :)

I'd use minlog, personally. It's extremely simple, as the logging class is a few hundred lines of code.

In my situation, it was Application Pool. It is set to restart when idle for xx mins. When I set it to not restart, it seems to use value from Web Config.

To select and element where you know only the attribute value you can use the below jQuery script

var src = $('.conversation_img[alt="example"]').attr('src');

Please refer the jQuery Documentation for attribute equals selectors

Please also refer to the example in Demo

Following is the code incase you are not able to access the demo..

HTML

<div>
    <img alt="example" src="\images\show.jpg" />
    <img  alt="exampleAll" src="\images\showAll.jpg" />  

</div>

SCRIPT JQUERY

var src = $('img[alt="example"]').attr('src');
alert("source of image with alternate text = example - " + src);


var srcAll = $('img[alt="exampleAll"]').attr('src');
alert("source of image with alternate text = exampleAll - " + srcAll );

Output will be

Two Alert messages each having values

1. source of image with alternate text = example - \images\show.jpg
2. source of image with alternate text = exampleAll - \images\showAll.jpg

The examples contained in this blog post do the trick.

The real problem is that the variable line always has a value. The test for "no matches found" is whether there is a match so the code "if line == None:" should be replaced with "else:"

this one System.IO.Path.GetDirectory(Application.ExecutablePath) changed to System.IO.Path.GetDirectoryName(Application.ExecutablePath)

To complete Sunit's answer, you can use a selector, not to the text string but to the textColorHint. You must add this attribute on your editText:

android:textColorHint="@color/text_hint_selector"

And your text_hint_selector should be:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:color="@android:color/transparent" />
    <item android:color="@color/hint_color" />
</selector>

echo $STRING | cut -d " " -f $N

Maybe you want to use CSS "clip-path" (Works with transparency and background)

"clip-path" reference: https://developer.mozilla.org/en-US/docs/Web/CSS/clip-path

You can also find create_tables.sql file it phpMyAdmin's repo. Just import it from phpMyAdmin panel. It should work.

I have used VB Decompiler Lite (http://www.vb-decompiler.org/) in the past, and although it does not give you the original source code, it does give you a lot of information such as method names, some variable strings, etc. With more knowledge (or with the full version) it might be possible to get even more than this.

gcc objectfiles -o program -Wl,-Bstatic -ls1 -ls2 -Wl,-Bdynamic -ld1 -ld2

you can also use: -static-libgcc -static-libstdc++ flags for gcc libraries

keep in mind that if libs1.so and libs1.a both exists, the linker will pick libs1.so if it's before -Wl,-Bstatic or after -Wl,-Bdynamic. Don't forget to pass -L/libs1-library-location/ before calling -ls1.

Every Set has an iterator(). A normal HashSet's iterator is quite random, a TreeSet does it by sort order, a LinkedHashSet iterator iterates by insert order.

You can't replace an element in a LinkedHashSet, however. You can remove one and add another, but the new element will not be in the place of the original. In a LinkedHashMap, you can replace a value for an existing key, and then the values will still be in the original order.

Also, you can't insert at a certain position.

Maybe you'd better use an ArrayList with an explicit check to avoid inserting duplicates.

Create a new package And then move the classes of default package in new package and use those classes

You can just go for String replace method.-

line1 = line1.replace("\"", "");

If you are using React Router, use this:

<Link to="/files/myfile.pdf" target="_blank" download>Download</Link>

Where /files/myfile.pdf is inside your public folder.

var test = {'red':'#FF0000', 'blue':'#0000FF'};_x000D_
delete test.blue; // or use => delete test['blue'];_x000D_
console.log(test);

this deletes test.blue

You should follow the guidelines on Add a secondary horizontal axis:

Add a secondary horizontal axis

To complete this procedure, you must have a chart that displays a secondary vertical axis. To add a secondary vertical axis, see Add a secondary vertical axis.

1. Click a chart that displays a secondary vertical axis. This displays the Chart Tools, adding the Design, Layout, and Format tabs.

2. On the Layout tab, in the Axes group, click Axes.

   

3. Click Secondary Horizontal Axis, and then click the display option that you want.

Add a secondary vertical axis

You can plot data on a secondary vertical axis one data series at a time. To plot more than one data series on the secondary vertical axis, repeat this procedure for each data series that you want to display on the secondary vertical axis.

1. In a chart, click the data series that you want to plot on a secondary vertical axis, or do the following to select the data series from a list of chart elements:

   • Click the chart.

     This displays the Chart Tools, adding the Design, Layout, and Format tabs.

   • On the Format tab, in the Current Selection group, click the arrow in the Chart Elements box, and then click the data series that you want to plot along a secondary vertical axis.

     

2. On the Format tab, in the Current Selection group, click Format Selection. The Format Data Series dialog box is displayed.

   Note: If a different dialog box is displayed, repeat step 1 and make sure that you select a data series in the chart.

3. On the Series Options tab, under Plot Series On, click Secondary Axis and then click Close.

   A secondary vertical axis is displayed in the chart.

4. To change the display of the secondary vertical axis, do the following:

   • On the Layout tab, in the Axes group, click Axes.

   • Click Secondary Vertical Axis, and then click the display option that you want.

5. To change the axis options of the secondary vertical axis, do the following:

   • Right-click the secondary vertical axis, and then click Format Axis.

   • Under Axis Options, select the options that you want to use.

I used below code and it's working fine for me. :

let jsonText = "{\"userName\":\"Bhavsang\"}"
var dictonary:NSDictionary?
    
if let data = jsonText.dataUsingEncoding(NSUTF8StringEncoding) {
        
     do {
            dictonary =  try NSJSONSerialization.JSONObjectWithData(data, options: [.allowFragments]) as? [String:AnyObject]
        
            if let myDictionary = dictonary
              {
                  print(" User name is: \(myDictionary["userName"]!)")
              }
            } catch let error as NSError {
            
            print(error)
         }
}

STA (Single Threaded Apartment) is basically the concept that only one thread will interact with your code at a time. Calls into your apartment are marshaled via windows messages (using a non-visible) window. This allows calls to be queued and wait for operations to complete.

MTA (Multi Threaded Apartment) is where many threads can all operate at the same time and the onus is on you as the developer to handle the thread security.

There is a lot more to learn about threading models in COM, but if you are having trouble understanding what they are then I would say that understanding what the STA is and how it works would be the best starting place because most COM objects are STA’s.

Apartment Threads, if a thread lives in the same apartment as the object it is using then it is an apartment thread. I think this is only a COM concept because it is only a way of talking about the objects and threads they interact with…

Also check if all dirs which you wrote in the my.ini exists.

My problem was that tmpdir doeesn`t exist so MySQL daemon falls with error 1067.

[mysqld]
port= 3306
tmpdir = "C:/tmp"

In this case C:/tmp must exists.

These are literals and are described in section 3.10 of the Java language spec.

Bootstrap has it's own centering class named text-center.

<div class="span7 text-center"></div>

If you want to be able to revoke user tokens, you can keep track of all issued tokens on your DB and check if they're valid (exist) on a session-like table. The downside is that you'll hit the DB on every request.

I haven't tried it, but i suggest the following method to allow token revocation while keeping DB hits to a minimum -

To lower the database checks rate, divide all issued JWT tokens into X groups according to some deterministic association (e.g., 10 groups by first digit of the user id).

Each JWT token will hold the group id and a timestamp created upon token creation. e.g., { "group_id": 1, "timestamp": 1551861473716 }

The server will hold all group ids in memory and each group will have a timestamp that indicates when was the last log-out event of a user belonging to that group. e.g., { "group1": 1551861473714, "group2": 1551861487293, ... }

Requests with a JWT token that have an older group timestamp, will be checked for validity (DB hit) and if valid, a new JWT token with a fresh timestamp will be issued for client's future use. If the token's group timestamp is newer, we trust the JWT (No DB hit).

So -

1. We only validate a JWT token using the DB if the token has an old group timestamp, while future requests won't get validated until someone in the user's group will log-out.
2. We use groups to limit the number of timestamp changes (say there's a user logging in and out like there's no tomorrow - will only affect limited number of users instead of everyone)
3. We limit the number of groups to limit the amount of timestamps held in memory
4. Invalidating a token is a breeze - just remove it from the session table and generate a new timestamp for the user's group.

CREATE UNIQUE INDEX foo ON table_name (field_name)

You have to remove duplicate values on that column before executes that sql. Any existing duplicate value on that column will lead you to mysql error 1062

There exists an on-line tool called IETransformsTranslator. With this tool you can make matrix filter transforms what works on IE6,IE7 & IE8. Just paste you CSS3 transform functions (e.g. rotate(15deg) ) and it will do the rest. http://www.useragentman.com/IETransformsTranslator/

Javascript which runs on the client machine can't access the local disk file system due to security restrictions.

If you want to access the client's disk file system then look into an embedded client application which you serve up from your webpage, like an Applet, Silverlight or something like that. If you like to access the server's disk file system, then look for the solution in the server side corner using a server side programming language like Java, PHP, etc, whatever your webserver is currently using/supporting.

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

At the time of writing this I have discovered that chromedriver 2.46 or 2.36 works well with Chrome 75.0.3770.100

Documentation here: http://chromedriver.chromium.org/downloads states align driver and browser alike but I found I had issues even with the most up-to-date driver when using Chrome 75

I am running Selenium 2 on Windows 10 Machine.

function auth (req, res, next) {
  console.log(req.headers);
  var authHeader = req.headers.authorization;
  if (!authHeader) {
      var err = new Error('You are not authenticated!');
      res.setHeader('WWW-Authenticate', 'Basic');
      err.status = 401;
      next(err);
      return;
  }
  var auth = new Buffer.from(authHeader.split(' ')[1], 'base64').toString().split(':');
  var user = auth[0];
  var pass = auth[1];
  if (user == 'admin' && pass == 'password') {
      next(); // authorized
  } else {
      var err = new Error('You are not authenticated!');
      res.setHeader('WWW-Authenticate', 'Basic');      
      err.status = 401;
      next(err);
  }
}
app.use(auth);

It seems that when this error appears it is an indication that the selenium-java plugin for maven is out-of-date.

Changing the version in the pom.xml should fix the problem

This solution worked for me

    ;(function($){
        // your code
    })(jQuery);

Move your code inside the closure and use $ instead of jQuery

I found the above solution in https://magento.stackexchange.com/questions/33348/uncaught-typeerror-undefined-is-not-a-function-when-using-a-jquery-plugin-in-ma

after seraching too much

The "reference" Java implementation by Sean Leary is here on github. Make sure to have the latest version - different libraries pull in versions buggy old versions from 2009.

Java EE 7 has a JSON API in javax.json, see the Javadoc. From what I can tell, it doesn't have a simple method to marshall any object to JSON, you need to construct a JsonObject or a JsonArray.

import javax.json.*;

JsonObject value = Json.createObjectBuilder()
 .add("firstName", "John")
 .add("lastName", "Smith")
 .add("age", 25)
 .add("address", Json.createObjectBuilder()
     .add("streetAddress", "21 2nd Street")
     .add("city", "New York")
     .add("state", "NY")
     .add("postalCode", "10021"))
 .add("phoneNumber", Json.createArrayBuilder()
     .add(Json.createObjectBuilder()
         .add("type", "home")
         .add("number", "212 555-1234"))
     .add(Json.createObjectBuilder()
         .add("type", "fax")
         .add("number", "646 555-4567")))
 .build();

JsonWriter jsonWriter = Json.createWriter(...);
jsonWriter.writeObject(value);
jsonWriter.close();

But I assume the other libraries like GSON will have adapters to create objects implementing those interfaces.

Run either of these a few second apart. You'll detect the high CPU connection. Or: stored CPU in a local variable, WAITFOR DELAY, compare stored and current CPU values

select * from master..sysprocesses
where status = 'runnable' --comment this out
order by CPU
desc

select * from master..sysprocesses
order by CPU
desc

May not be the most elegant but it'd effective and quick.

The 2 domains mydomain.com and subdomain.mydomain.com can only share cookies if the domain is explicitly named in the Set-Cookie header. Otherwise, the scope of the cookie is restricted to the request host. (This is referred to as a "host-only cookie". See What is a host only cookie?)

For instance, if you sent the following header from subdomain.mydomain.com, then the cookie won't be sent for requests to mydomain.com:

Set-Cookie: name=value

However if you use the following, it will be usable on both domains:

Set-Cookie: name=value; domain=mydomain.com

This cookie will be sent for any subdomain of mydomain.com, including nested subdomains like subsub.subdomain.mydomain.com.

In RFC 2109, a domain without a leading dot meant that it could not be used on subdomains, and only a leading dot (.mydomain.com) would allow it to be used across multiple subdomains (but not the top-level domain, so what you ask was not possible in the older spec).

However, all modern browsers respect the newer specification RFC 6265, and will ignore any leading dot, meaning you can use the cookie on subdomains as well as the top-level domain.

In summary, if you set a cookie like the second example above from mydomain.com, it would be accessible by subdomain.mydomain.com, and vice versa. This can also be used to allow sub1.mydomain.com and sub2.mydomain.com to share cookies.

I wrote a realpath utility for OS X which can provide the same results as readlink -f.

Here is an example:

(jalcazar@mac tmp)$ ls -l a
lrwxrwxrwx 1 jalcazar jalcazar 11  8? 25 19:29 a -> /etc/passwd

(jalcazar@mac tmp)$ realpath a
/etc/passwd

If you are using MacPorts, you can install it with the following command: sudo port selfupdate && sudo port install realpath.

You could set your _JAVA_OPTIONS environmental variable. For example in bash this would do the trick:

export _JAVA_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir

I put that into my bash login script and it seems to do the trick.

Set overflow-y property to auto, or remove the property altogether if it is not inherited.

I found the answer is very very simple...

// It is in java, but it should be same in pyspark
Column col = ds.col("colName"); //the column object
String theNameOftheCol = col.toString();

The variable "theNameOftheCol" is "colName"

After a few years and many attempts (I tried all the answers given here, but all of them had minor drawbacks at the end), now I realize that there is a better way than wanting to start, stop, restart a daemon directly from Python: use the OS tools instead.

For example, for Linux, instead of doing python myapp start and python myapp stop, I do this to start the app:

screen -S myapp python myapp.py    
CTRL+A, D to detach

or screen -dmS myapp python myapp.py to start and detach it in one command.

Then:

screen -r myapp

to attach to this terminal again. Once in the terminal, it's possible to use CTRL+C to stop it.

This is for Phonegap 3.0.x to 3.3.x. For PhoneGap 3.4.0 and higher see below.

Found part of the answer here, at Phonegap documentation. The full process is the following:

1. Open a command line window, and go to /path/to/your/project/platforms/android/cordova.

2. Run build --release. This creates an unsigned release APK at /path/to/your/project/platforms/android/bin folder, called YourAppName-release-unsigned.apk.

3. Sign and align the APK using the instructions at android developer official docs.

Thanks to @LaurieClark for the link (http://iphonedevlog.wordpress.com/2013/08/16/using-phonegap-3-0-cli-on-mac-osx-10-to-build-ios-and-android-projects/), and the blogger who post it, because it put me on the track.

I also had this same issue. My console window was no longer open, but I was able to see my application running by going to processes within task manager. The process name was the name of my application. Once I ended the process I was able to build and compile my code with no issues.

If you want the header to be easily reused across multiple lists, take a look at the version 1.2.0 of recyclerview library. It introduces ConcatAdapter class which concatenates multiple adapters into a single one. So you can create a header adapter and easily combine it with any other adapter, like:

myRecyclerView.adapter = ConcatAdapter(headerAdapter, listAdapter)

The announcement article contains a sample how to display a loading progress in header and footer using ConcatAdapter.

For the moment when I post this answer the version 1.2.0 of the library is in alpha stage, so the api might change. You can check the status here.

Another possibility is to set up a callback that tracks completed tasks:

function onApiResults(requestId, response, results) {
    requestsCompleted |= requestId;

    switch(requestId) {
        case REQUEST_API1:
            ...
            [Call API2]
            break;
        case REQUEST_API2:
            ...
            [Call API3]
            break;
        case REQUEST_API3:
            ...
            break;
    }

    if(requestId == requestsNeeded)
        response.end();
}

Then simply assign an ID to each and you can set up your requirements for which tasks must be completed before closing the connection.

const var REQUEST_API1 = 0x01;
const var REQUEST_API2 = 0x02;
const var REQUEST_API3 = 0x03;
const var requestsNeeded = REQUEST_API1 | REQUEST_API2 | REQUEST_API3;

Okay, it's not pretty. It is just another way to make sequential calls. It's unfortunate that NodeJS does not provide the most basic synchronous calls. But I understand what the lure is to asynchronicity.

Try:

npm install underscore

:)

There is no unserscore package in npm registry.

Come out of the "python interpreter."

1. Check out your PATH variable c:\python27
2. cd and your file location. 3.Now type Python yourfilename.py.

I hope this should work

Another Solutions for reversing a String in Java.

Convert you string into a char array using .toCharArray() function.

public static char[] reverse(char in[], int inLength, char out[],
            int tractOut) {

        if (inLength >= 0) {
            out[tractOut] = in[inLength];
            reverse(in, inLength - 1, out, tractOut + 1);
        }

        return null;

    }

Same Problem I had... I was writing all the script in a seperate file and was adding it through tag into the end of the HTML file after body tag. After moving the the tag inside the body tag it works fine. before :

</body>
<script>require('../script/viewLog.js')</script>

after :

<script>require('../script/viewLog.js')</script>
</body>

A note on the difference in speed. Attach the following snipet to an onclick call:

function myfunc()
{
    var timer = new Date();
    
        for(var i = 0; i < 10000; i++)
        {
            //document.getElementById('myID');
            $('#myID')[0];
        }
    

    console.log('timer: ' + (new Date() - timer));
}

Alternate commenting one out and then comment the other out. In my tests,

document.getElementbyId averaged about 35ms (fluctuating from 25ms up to 52ms on about 15 runs)

On the other hand, the

jQuery averaged about 200ms (ranging from 181ms to 222ms on about 15 runs).

From this simple test you can see that the jQuery took about 6 times as long.

Of course, that is over 10000 iterations so in a simpler situation I would probably use the jQuery for ease of use and all of the other cool things like .animate and .fadeTo. But yes, technically getElementById is quite a bit faster.

This should be set directly in the CSS.

.forum {background-color: #123456}
.forum:hover {background-color: #380606}

If you are worried about the fact the IE6 will not accept hover over elements which are not links, you can use the hover event of jQuery for compatibility.

Based on the above post concerning the ScheduledThreadPoolExecutor, I came up with a utility that suited my needs (wanted to fire a method every 3 seconds):

class MyActivity {
    private ScheduledThreadPoolExecutor mDialogDaemon;

    private void initDebugButtons() {
        Button btnSpawnDialogs = (Button)findViewById(R.id.btn_spawn_dialogs);
        btnSpawnDialogs.setVisibility(View.VISIBLE);
        btnSpawnDialogs.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                spawnDialogs();
            }
        });
    }

    private void spawnDialogs() {
        if (mDialogDaemon != null) {
            mDialogDaemon.shutdown();
            mDialogDaemon = null;
        }
        mDialogDaemon = new ScheduledThreadPoolExecutor(1);
        // This process will execute immediately, then execute every 3 seconds.
        mDialogDaemon.scheduleAtFixedRate(new Runnable() {
            @Override
            public void run() {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // Do something worthwhile
                    }
                });
            }
        }, 0L, 3000L, TimeUnit.MILLISECONDS);
    }
}

In 64 bit windows machines the COM components need to register itself in HKEY_CLASSES_ROOT\CLSID (64 bit component) OR HKEY_CLASSES_ROOT\Wow6432Node\CLSID (32 bit component) . If your application is a 32 bit application running on 64-bit machine the COM library would typically look for the GUID under Wow64 node and if your application is a 64 bit application, the COM library would try to load from HKEY_CLASSES_ROOT\CLSID. Make sure you are targeting the correct platform and ensure you have installed the correct version of library(32/64 bit).

In Python, "privacy" depends on "consenting adults'" levels of agreement - you can't force it (any more than you can in real life;-). A single leading underscore means you're not supposed to access it "from the outside" -- two leading underscores (w/o trailing underscores) carry the message even more forcefully... but, in the end, it still depends on social convention and consensus: Python's introspection is forceful enough that you can't handcuff every other programmer in the world to respect your wishes.

((Btw, though it's a closely held secret, much the same holds for C++: with most compilers, a simple #define private public line before #includeing your .h file is all it takes for wily coders to make hash of your "privacy"...!-))

psql does this, and if you start psql with:

psql -E

it will show you exactly what query is executed. In the case of finding foreign keys, it's:

SELECT conname,
  pg_catalog.pg_get_constraintdef(r.oid, true) as condef
FROM pg_catalog.pg_constraint r
WHERE r.conrelid = '16485' AND r.contype = 'f' ORDER BY 1

In this case, 16485 is the oid of the table I'm looking at - you can get that one by just casting your tablename to regclass like:

WHERE r.conrelid = 'mytable'::regclass

Schema-qualify the table name if it's not unique (or the first in your search_path):

WHERE r.conrelid = 'myschema.mytable'::regclass

the best way to disable Google chrome auto update is as follows

• Go to oldversion dot com and download old version of google
• Use Advanced unsinstaller to completely uninstall current (Updated) version. This will also get rid of registry entries
• Download update freezer and create a shortcut on desktop
• Disable internet
• Restart PC
• With internet disabled, install old version of Chrome
• Ope Update Freezer and Disable Google auto update

You are done

for (let i of Array(100).keys()) {
    console.log(i)
}

These two commands should do it:

:set autoindent
:set cindent

For bonus points put them in a file named .vimrc located in your home directory on linux

You can use the data in inline

 <style>   
 td { text-align: justify; }
 td:after { content: attr(data-content); display: inline-block; width: 100%; }
</style>

<table><tr><td data-content="post"></td></tr></table>

I was having this issue too. The scraper shows the right information, but the share url was still populated with old data.

The way I got around this was to use the feed method, instead of share, and then populate the data manually (which isn't exposed with the share method)

Something like this:

shareToFB = () => {
    window.FB.ui({
    method: 'feed',
    link: `signup.yourdomain.com/?referrer=${this.props.subscriber.sid}`,
    name: 'THIS WILL OVERRIDE OG:TITLE TAG',
    description: 'THIS WILL OVERRIDE OG:DESCRIPTION TAG',
    caption: 'THIS WILL OVERRIDE THE OG:URL TAG'
  });
};

More on schemas:

In SQL 2005 a schema is a way to group objects. It is a container you can put objects into. People can own this object. You can grant rights on the schema.

In 2000 a schema was equivalent to a user. Now it has broken free and is quite useful. You could throw all your user procs in a certain schema and your admin procs in another. Grant EXECUTE to the appropriate user/role and you're through with granting EXECUTE on specific procedures. Nice.

The dot notation would go like this:

Server.Database.Schema.Object

or

myserver01.Adventureworks.Accounting.Beans

Update: Webm with an alpha channel is now supported in Chrome and Firefox.

For other browers, there are workarounds, but they involve re-rendering the video using Canvas and it is kind of a hack. seeThru is one example. It works pretty well on HTML5 desktop browsers (even IE9) but it doesn't seem to work very well on mobile. I couldn't get it to work at all on Chrome for Android. It did work on Firefox for Android but with a pretty lousy framerate. I think you might be out of luck for mobile, although I'd love to be proven wrong.

Try this:

First go to the anaconda3 binaries directory by running

 cd anaconda3/bin

and now use this following command to open the anaconda-navigator

./anaconda-navigator

You could use a variable to make the calculation and use toFixed when you set the #diskamountUnit element value:

var amount = $("#disk").slider("value") * 1.60;
$("#diskamountUnit").val('$' + amount.toFixed(2));

You can also do that in one step, in the val method call but IMO the first way is more readable:

$("#diskamountUnit").val('$' + ($("#disk").slider("value") * 1.60).toFixed(2));

Not OP's answer but as this was the first question that popped up for me in google, Id also like to add that users searching for this might need to reseed their table, which was the case for me

DBCC CHECKIDENT(tablename)

Most of the time your background color is different from the background of your table. Since there are spaces between the cells, those spaces will create the illusion of lines with the color of the background behind the table.

The solution is to get rid of those spaces.

Inside the table tag write:

cellspacing="0"

use this

System.Configuration.ConfigurationSettings.AppSettings.Get("Keyname")

After so much of searches, i have found following working solution

function isEquivalent(a, b) {
   // Create arrays of property names
   var aProps = Object.getOwnPropertyNames(a);
   var bProps = Object.getOwnPropertyNames(b);

  // If number of properties is different, objects are not equivalent
  if (aProps.length != bProps.length) {
     return false;
  }

  for (var i = 0; i < aProps.length; i++) {
     var propName = aProps[i];

    // If values of same property are not equal, objects are not equivalent
     if (a[propName] !== b[propName]) {
         return false;
     }
  }

// If we made it this far, objects are considered equivalent
return true; }

One thing to be aware of is that many Linux netfilter firewalls are misconfigured.

If you have something like:

-A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

-A FORWARD -p tcp -j REJECT --reject-with tcp-reset

then packet reordering can result in the firewall considering the packets invalid and thus generating resets which will then break otherwise healthy connections.

Reordering is particularly likely with a wireless network.

This should instead be:

-A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT

-A FORWARD -m state --state INVALID -j DROP

-A FORWARD -p tcp -j REJECT --reject-with tcp-reset

Basically anytime you have:

... -m state --state RELATED,ESTABLISHED -j ACCEPT

it should immediately be followed by:

... -m state --state INVALID -j DROP

It's better to drop a packet then to generate a potentially protocol disrupting tcp reset. Resets are better when they're provably the correct thing to send... since this eliminates timeouts. But if there's any chance they're invalid then they can cause this sort of pain.

Use Number from the numbers module to test isinstance(n, Number) (available since 2.6).

isinstance(n, numbers.Number)

Here it is in action with various kinds of numbers and one non-number:

>>> from numbers import Number
... from decimal import Decimal
... from fractions import Fraction
... for n in [2, 2.0, Decimal('2.0'), complex(2,0), Fraction(2,1), '2']:
...     print '%15s %s' % (n.__repr__(), isinstance(n, Number))
              2 True
            2.0 True
 Decimal('2.0') True
         (2+0j) True
 Fraction(2, 1) True
            '2' False

This is, of course, contrary to duck typing. If you are more concerned about how an object acts rather than what it is, perform your operations as if you have a number and use exceptions to tell you otherwise.

You can install any current version of Anaconda. You can then make a conda environment with your particular needs from the documentation

conda create -n tensorflowproject python=3.5 tensorflow ipython

This command has a specific version for python and when this tensorflowproject environment gets updated it will upgrade to Python 3.5999999999 but never go to 3.6 . Then you switch to your environment using either

source activate tensorflowproject

for linux/mac or

activate tensorflowproject

on windows

Your approach won't deal with lot of names correctly but...

SELECT CASE
         WHEN name LIKE '% %' THEN LEFT(name, Charindex(' ', name) - 1)
         ELSE name
       END,
       CASE
         WHEN name LIKE '% %' THEN RIGHT(name, Charindex(' ', Reverse(name)) - 1)
       END
FROM   YourTable 

Try this instead to only select the visible elements under the tbody:

$('tbody :visible').highlight(myArray[i]);

You have to override the bootstrap default by being a bit more specific. Try this for a black background:

html body {

I didn't want to have to have the YouTube app present on the device so I used this tutorial:

http://www.viralandroid.com/2015/09/how-to-embed-youtube-video-in-android-webview.html

...to produce this code in my app:

WebView mWebView; 

@Override
public void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.video_webview);
    mWebView=(WebView)findViewById(R.id.videoview);

    //build your own src link with your video ID
    String videoStr = "<html><body>Promo video<br><iframe width=\"420\" height=\"315\" src=\"https://www.youtube.com/embed/47yJ2XCRLZs\" frameborder=\"0\" allowfullscreen></iframe></body></html>";

    mWebView.setWebViewClient(new WebViewClient() {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
                return false;
        }
    });
    WebSettings ws = mWebView.getSettings();
    ws.setJavaScriptEnabled(true);
    mWebView.loadData(videoStr, "text/html", "utf-8");

}

//video_webview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="0dp"
    android:layout_marginRight="0dp"
    android:background="#000000"
    android:id="@+id/bmp_programme_ll"
    android:orientation="vertical" >

   <WebView
    android:id="@+id/videoview" 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />  
</LinearLayout>     

This worked just how I wanted it. It doesn't autoplay but the video streams within my app. Worth noting that some restricted videos won't play when embedded.

It seems you don't want to keep the whole DataTable as a copy, because you only need some rows, right? If you got a creteria you can specify with a select on the table, you could copy just those rows to an extra backup array of DataRow like

DataRow[] rows = sourceTable.Select("searchColumn = value");

The .Select() function got several options and this one e.g. can be read as a SQL

SELECT * FROM sourceTable WHERE searchColumn = value;

Then you can import the rows you want as described above.

targetTable.ImportRows(rows[n])

...for any valid n you like, but the columns need to be the same in each table.

Some things you should know about ImportRow is that there will be errors during runtime when using primary keys!

First I wanted to check whether a row already existed which also failed due to a missing primary key, but then the check always failed. In the end I decided to clear the existing rows completely and import the rows I wanted again.

The second issue did help to understand what happens. The way I'm using the import function is to duplicate rows with an exchanged entry in one column. I realized that it always changed and it still was a reference to the row in the array. I first had to import the original and then change the entry I wanted.

The reference also explains the primary key errors that appeared when I first tried to import the row as it really was doubled up.

Update:

This linked answer describes a cleaner, simpler way of doing the same thing with C# syntax.

Original post

This is Microsoft's recommended way to handle WCF client calls:

For more detail see: Expected Exceptions

try
{
    ...
    double result = client.Add(value1, value2);
    ...
    client.Close();
}
catch (TimeoutException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}
catch (CommunicationException exception)
{
    Console.WriteLine("Got {0}", exception.GetType());
    client.Abort();
}

Additional information

So many people seem to be asking this question on WCF that Microsoft even created a dedicated sample to demonstrate how to handle exceptions:

c:\WF_WCF_Samples\WCF\Basic\Client\ExpectedExceptions\CS\client

Download the sample: C# or VB

Considering that there are so many issues involving the using statement, (heated?) Internal discussions and threads on this issue, I'm not going to waste my time trying to become a code cowboy and find a cleaner way. I'll just suck it up, and implement WCF clients this verbose (yet trusted) way for my server applications.

Acknowledging the fact that the asker specifically requested jQuery and that the answer selected is correct, it should be noted that this problem doesn't actually need jQuery per say. If one desires to solve this problem without it, one can simply set the onClick attribute of the checkboxes that he or she wants to add additional functionality to, like so:

HTML:

<form id="myform">
  <input type="checkbox" name="check1" value="check1" onClick="cbChanged(this);">
  <input type="checkbox" name="check2" value="check2" onClick="cbChanged(this);">
</form>

javascript:

function cbChanged(checkboxElem) {
  if (checkboxElem.checked) {
    // Do something special
  } else {
    // Do something else
  }
}

Fiddle: http://jsfiddle.net/Y9f66/1/

have you tried something like this:

if [ $# -eq 0 ] || [ $# -gt 1 ] 
then
 echo "$#"
fi

Its is not necessary to store commands in variables even as you need to use it later. just execute it as per normal. If you store in variable, you would need some kind of eval statement or invoke some unnecessary shell process to "execute your variable".

Me, I'd do it something like this:

HTML:

onclick="myfunction({path:'/myController/myAction', ok:myfunctionOnOk, okArgs:['/myController2/myAction2','myParameter2'], cancel:myfunctionOnCancel, cancelArgs:['/myController3/myAction3','myParameter3']);"

JS:

function myfunction(params)
{
  var path = params.path;

  /* do stuff */

  // on ok condition 
  params.ok(params.okArgs);

  // on cancel condition
  params.cancel(params.cancelArgs);  
}

But then I'd also probable be binding a closure to a custom subscribed event. You need to add some detail to the question really, but being first-class functions are easily passable and getting params to them can be done any number of ways. I would avoid passing them as string labels though, the indirection is error prone.

I like...

@data = `cat /var/tmp/somefile`;

It's not as glamorous as others, but, it works all the same. And...

$todays_data = '/var/tmp/somefile' ;
open INFILE, "$todays_data" ; 
@data = <INFILE> ; 
close INFILE ;

Cheers.

According to here, int(11) will take 4 bytes of space that is 32 bits of space with 2^(31) = 2147483648 max value and -2147483648min value. One bit is for sign.

 <html>
<head>
    <title>Print</title>
    <script type="text/javascript">
window.print();
document.margin='none';
</script>
</head>
<body>
  <p>hello</p>
  <p>hi</p>
</body>
</html>

//place it in a script file or in the script tag.

This will remove all the margins and you won't be able to see the headers and footers.

// Wait up to 5 seconds with no minimum for a UI element to be found
WebDriverWait wait = new WebDriverWait(_pagedriver, TimeSpan.FromSeconds(5));
IWebElement title = wait.Until<IWebElement>((d) =>
{
    return d.FindElement(By.ClassName("MainContentHeader"));
});

the css solution works, however you do not really get control on the styling. In my case I wanted a bit more space after the line break. Here is a directive I created to handle this (typescript):

function preDirective(): angular.IDirective {
    return {
        restrict: 'C',
        priority: 450,
        link: (scope, el, attr, ctrl) => {
            scope.$watch(
                () => el[0].innerHTML,
                (newVal) => {
                    let lineBreakIndex = newVal.indexOf('\n');
                    if (lineBreakIndex > -1 && lineBreakIndex !== newVal.length - 1 && newVal.substr(lineBreakIndex + 1, 4) != '</p>') {
                        let newHtml = `<p>${replaceAll(el[0].innerHTML, '\n\n', '\n').split('\n').join('</p><p>')}</p>`;
                        el[0].innerHTML = newHtml;
                    }
                }
            )
        }
    };

    function replaceAll(str, find, replace) {
        return str.replace(new RegExp(escapeRegExp(find), 'g'), replace);
    }

    function escapeRegExp(str) {
        return str.replace(/([.*+?^=!:${}()|\[\]\/\\])/g, "\\$1");
    }
}

angular.module('app').directive('pre', preDirective);

Use:

<div class="pre">{{item.description}}</div>

All it does is wraps each part of the text in to a <p> tag. After that you can style it however you want.

I have answered this question here: How to resize images proportionally / keeping the aspect ratio?. I am copying it here because I really think it is a very reliable method :)

 /**
  * Conserve aspect ratio of the original region. Useful when shrinking/enlarging
  * images to fit into a certain area.
  *
  * @param {Number} srcWidth width of source image
  * @param {Number} srcHeight height of source image
  * @param {Number} maxWidth maximum available width
  * @param {Number} maxHeight maximum available height
  * @return {Object} { width, height }
  */
function calculateAspectRatioFit(srcWidth, srcHeight, maxWidth, maxHeight) {

    var ratio = Math.min(maxWidth / srcWidth, maxHeight / srcHeight);

    return { width: srcWidth*ratio, height: srcHeight*ratio };
 }

Here is an example:

MySqlConnection con = new MySqlConnection(
    "Server=ServerName;Database=DataBaseName;UID=username;Password=password");

MySqlCommand cmd = new MySqlCommand(
    " INSERT Into Test (lat, long) VALUES ('"+OSGconv.deciLat+"','"+
    OSGconv.deciLon+"')", con);

con.Open();
cmd.ExecuteNonQuery();
con.Close();

When there is no records returned from Database for a particular condition and When I tried to access the rs.getString(1); I got this error "exhausted resultset".

Before the issue, my code was:

rs.next();
sNr= rs.getString(1);

After the fix:

while (rs.next()) {
    sNr = rs.getString(1);
}

It wraps around.

e.g:

public class Test {

    public static void main(String[] args) {
        int i = Integer.MAX_VALUE;
        int j = Integer.MIN_VALUE;

        System.out.println(i+1);
        System.out.println(j-1);
    }
}

prints

-2147483648
2147483647

There is a point to only put commands and options in variables.

#! /bin/bash

if [ $# -ne 2 ]
then
    echo "Usage: `basename $0` DIRECTORY BACKUP_DIRECTORY"
    exit 1
fi

. standard_tools    

directory=$1
backup_directory=$2
current_date=$(date +%Y-%m-%dT%H-%M-%S)
backup_file="${backup_directory}/${current_date}.backup"

${tar_create} "${directory}" | ${openssl} | ${split_1024} "$backup_file"

You can relocate the commands to another file you source, so you can reuse the same commands and options across many scripts. This is very handy when you have a lot of scripts and you want to control how they all use tools. So standard_tools would contain:

export tar_create="tar cv"
export openssl="openssl des3 -salt"
export split_1024="split -b 1024m -"

When you define your function using this syntax:

def someFunc(*args):
    for x in args
        print x

You're telling it that you expect a variable number of arguments. If you want to pass in a List (Array from other languages) you'd do something like this:

def someFunc(myList = [], *args):
    for x in myList:
        print x

Then you can call it with this:

items = [1,2,3,4,5]

someFunc(items)

You need to define named arguments before variable arguments, and variable arguments before keyword arguments. You can also have this:

def someFunc(arg1, arg2, arg3, *args, **kwargs):
    for x in args
        print x

Which requires at least three arguments, and supports variable numbers of other arguments and keyword arguments.

Even a single space works

...Just open this answer for edit to see it.

Nested lists, deeper levels: ---- leave here an empty row * first level A item - no space in front the bullet character * second level Aa item - 1 space is enough * third level Aaa item - 5 spaces min * second level Ab item - 4 spaces possible too * first level B item

Nested lists, deeper levels:

• first level A item - no space in front the bullet character
  • second level Aa item - 1 space is enough
    • third level Aaa item - 5 spaces min
  • second level Ab item - 4 spaces possible too

• first level B item

  Nested lists, deeper levels:
   ...Skip a line and indent eight spaces. (as said in the editor-help, just on this page)
  * first level A item - no space in front the bullet character
   * second level Aa item - 1 space is enough
       * third level Aaa item - 5 spaces min
      * second level Ab item - 4 spaces possible too
  * first level B item
  

Why can't you use absolute positioning? Vertical-align does not work (except for tables). Make your container's position: relative. Then absolutely position the internal divs using bottom: 0; Should work like a charm.

EDIT By zoidberg (i will update the answer instead)

<div style="position:relative; border: 1px solid red;width: 40px; height: 40px;">
   <div style="border:1px solid green;position: absolute; bottom: 0; left: 0; width: 20px; height: 20px;"></div>
   <div style="border:1px solid blue;position: absolute; bottom: 0; left: 20px; width: 20px height: 20px;"></div>

SQL Server and .Net Data Type mapping

You might also want to check out ewd-qoper8: https://github.com/robtweed/ewd-qoper8

Here you go:

^[^<>]*$

This will test for string that has no < and no >

If you want to test for a string that may have < and >, but must also have something other you should use just

[^<>] (or ^.*[^<>].*$)

Where [<>] means any of < or > and [^<>] means any that is not of < or >.

And of course the mandatory link.

Use CTRL+D at each line and it will find the matching words and select them then you can use multiple cursors.

You can also use find to find all the occurrences and then it would be multiple cursors too.

This will do what you want:

<?php

$array = array(2 => 'a', 1 => 'b', 0 => 'c');

array_unshift($array, false); // Add to the start of the array
$array = array_values($array); // Re-number

// Remove the first index so we start at 1
$array = array_slice($array, 1, count($array), true);

print_r($array); // Array ( [1] => a [2] => b [3] => c ) 

?>

There's an interesting way which this can be achieved by using jQuery animate method in a unique way, where you call the animate method on a javascript Object which describes the from value and then you pass as the first parameter another js object which describes the to value, and a step function which handles each step of the animation according to the values described earlier.

Example - Animate transform translateY:

var $elm = $('h1'); // element to be moved_x000D_
_x000D_
function run( v ){_x000D_
  // clone the array (before "animate()" modifies it), and reverse it_x000D_
  var reversed = JSON.parse(JSON.stringify(v)).reverse();_x000D_
  _x000D_
  $(v[0]).animate(v[1], {_x000D_
      duration: 500,_x000D_
      step: function(val) {_x000D_
          $elm.css("transform", `translateY(${val}px)`); _x000D_
      },_x000D_
      done: function(){_x000D_
          run( reversed )_x000D_
      }_x000D_
  })_x000D_
};_x000D_
_x000D_
// "y" is arbitrary used as the key name _x000D_
run( [{y:0}, {y:80}] )

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_

You can also try ghex2 GNOME utilities. This give you the automated hex-to-ASCII on the side, as well as the various character/integer decodes at the bottom.

For your needs, it's like:

awk '{ printf "%-20s %-40s\n", $1, $2}'

Let me provide answers to both possible questions. Note that your existing title (and original post) ask a question different than what you seek in your edit and subsequent comment.

To position an element "fixed" relative to a parent element, you want position:absolute on the child element, and any position mode other than the default or static on your parent element.

For example:

#parentDiv { position:relative; }
#childDiv { position:absolute; left:50px; top:20px; }

This will position childDiv element 50 pixels left and 20 pixels down relative to parentDiv's position.

To position an element "fixed" relative to the window, you want position:fixed, and can use top:, left:, right:, and bottom: to position as you see fit.

For example:

#yourDiv { position:fixed; bottom:40px; right:40px; }

This will position yourDiv fixed relative to the web browser window, 40 pixels from the bottom edge and 40 pixels from the right edge.

The Connection String Which We Are Assigning from server side will be same as that From Web config File. The Catalog: Means To Database it is followed by Username and Password And DataClient The New sql connection establishes The connection to sql server by using the credentials in the connection string.. Then it is followed by sql command which retrives the required data in the dataset and then we assing them to required variables or controls to get the required task done

The only problem with cnoremap w!! is that it replaces w with ! (and hangs until you type the next char) whenever you type w! at the : command prompt. Like when you want to actually force-save with w!. Also, even if it's not the first thing after :.

Therefore I would suggest mapping it to something like <Fn>w. I personally have mapleader = F1, so I'm using <Leader>w.

You can use BIGINT as follows:

CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
   );

Rephrasing Yuri, Fábio, and Frosts answers for the Django noob (i.e. me) - almost certainly a simplification, but a good starting point?

• render_to_response() is the "original", but requires you putting context_instance=RequestContext(request) in nearly all the time, a PITA.

• direct_to_template() is designed to be used just in urls.py without a view defined in views.py but it can be used in views.py to avoid having to type RequestContext

• render() is a shortcut for render_to_response() that automatically supplies context_instance=Request.... Its available in the django development version (1.2.1) but many have created their own shortcuts such as this one, this one or the one that threw me initially, Nathans basic.tools.shortcuts.py

There is no standard unfortunately, this is one of the perils of installing from source. Some Makefiles will include an "uninstall", so

make uninstall

from the source directory may work. Otherwise, it may be a matter of manually undoing whatever the make install did.

make clean usually just cleans up the source directory - removing generated/compiled files and the like, probably not what you're after.

No, you can't do that. range() expects integer arguments. If you want to know if x is inside this range try some form of this:

print 0.0 <= x <= 0.5

Be careful with your upper limit. If you use range() it is excluded (range(0, 5) does not include 5!)

If you don't want to use jQuery you can try this approach:

public setCaretPosition() {
    const editableDiv = document.getElementById('contenteditablediv');
    const lastLine = this.input.nativeElement.innerHTML.replace(/.*?(<br>)/g, '');
    const selection = window.getSelection();
    selection.collapse(editableDiv.childNodes[editableDiv.childNodes.length - 1], lastLine.length);
}

editableDiv you editable element, don't forget to set an id for it. Then you need to get your innerHTML from the element and cut all brake lines. And just set collapse with next arguments.

You can do it without writing any code at all :) You just need to set the default value for the column in the database. You can do this in your migrations. For example:

create_table :projects do |t|
  t.string :status, :null => false, :default => 'P'
  ...
  t.timestamps
end

Hope that helps.

you can use this function to download file from base64.

function downloadPDF(pdf) {
const linkSource = `data:application/pdf;base64,${pdf}`;
const downloadLink = document.createElement("a");
const fileName = "abc.pdf";
downloadLink.href = linkSource;
downloadLink.download = fileName;
downloadLink.click();}

This code will made an anchor tag with href and download file. if you want to use button then you can call click method on your button click.

i hope this will help of you thanks

I tired all the answers and in the end i was able to fix it by adding pod library into the Xcode Build scheme , after i was able to run it, tried to remove this from the build scheme and still it worked fine for me. couldn't figure out the exact reason.

For Kotlin developers

(activity as YourActivityClassName).methodName()

For Java developers

((YourActivityClassName) getActivity()).methodName();

use

LDFLAGS= -L<Directory where the library resides> -l<library name>

Like :

LDFLAGS = -L. -lmine

for ensuring static compilation you can also add

LDFLAGS = -static

Or you can just get rid of the whole library searching, and link with with it directly.

say you have main.c fun.c

and a static library libmine.a

then you can just do in your final link line of the Makefile

$(CC) $(CFLAGS) main.o fun.o libmine.a

I recommendo to you use TtoC from ConvUnicode.h

const CString word= "hello";
const char* myFile = TtoC(path.GetString());

It is a macro to do conversions per Unicode

Open phpmyadmin, go to database and corresponding table to find it out.

You just can't be sure on a Unix system, that a .txt file truly is a text file. Your best bet is to use "file". Maybe try using:

file -ib "$file"

Then you can use a list of MIME types to match against or parse the first part of the MIME where you get stuff like "text", "application", etc.

What ever instance you are using to call the void method , You can just use ,Verfiy

For Example:

In My case its _Log is the instance and LogMessage is the method to be tested:

try
{
    this._log.Verify(x => x.LogMessage(Logger.WillisLogLevel.Info, Logger.WillisLogger.Usage, "Created the Student with name as"), "Failure");
}
Catch 
{
    Assert.IsFalse(ex is Moq.MockException);
}

Is the Verify throws an exception due to failure of the method the test would Fail ?

There's no easy solution. Each way has their pros and cons . But the canonical way is using the first option: multipart/form-data. As W3 recommendation guide says

The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.

We aren't sending forms,really, but the implicit principle still applies. Using base64 as a binary representation, is incorrect because you're using the incorrect tool for accomplish your goal, in other hand, the second option forces your API clients to do more job in order to consume your API service. You should do the hard work in the server side in order to supply an easy-to-consume API. The first option is not easy to debug, but when you do it, it probably never changes.

Using multipart/form-data you're sticked with the REST/http philosophy. You can view an answer to similar question here.

Another option if mixing the alternatives, you can use multipart/form-data but instead of send every value separate, you can send a value named payload with the json payload inside it. (I tried this approach using ASP.NET WebAPI 2 and works fine).

As already pointed out by @snishalaka, you can increase the number of inotify watchers.

However, I think the default number is high enough and is only reached when processes are not cleaned up properly. Hence, I simply restarted my computer as proposed on a related github issue and the error message was gone.

You mark the selected item on the <option> tag, not the <select> tag.

So your code should read something like this:

<select>
    <option value="January"<?php if ($row[month] == 'January') echo ' selected="selected"'; ?>>January</option>
    <option value="February"<?php if ($row[month] == 'February') echo ' selected="selected"'; ?>>February</option>
    ...
    ...
    <option value="December"<?php if ($row[month] == 'December') echo ' selected="selected"'; ?>>December</option>
</select>

You can make this less repetitive by putting all the month names in an array and using a basic foreach over them.

Shame on me...

I looked at the user guide and the first function is $this->db->insert_id();

This also works with activerecord inserts...

EDIT: I updated the link

Everything is possible only if there is enough time to research :)

What I got to do is like having people that I iterate into a ui:repeat and display names and other fields in inputs. But one of fields was singleSelect - A and depending on it value update another input - B. even ui:repeat do not have id I put and it appeared in the DOM tree

<ui:repeat id="peopleRepeat"
value="#{myBean.people}"
var="person" varStatus="status">

Than the ids in the html were something like:

myForm:peopleRepeat:0:personType
myForm:peopleRepeat:1:personType

Than in the view I got one method like:

<p:ajax event="change"
listener="#{myBean.onPersonTypeChange(person, status.index)}"/>

And its implementation was in the bean like:

String componentId = "myForm:peopleRepeat" + idx + "personType";
PrimeFaces.current().ajax().update(componentId);

So this way I updated the element from the bean with no issues. PF version 6.2

Good luck and happy coding :)

Just create an event calling bellow. In my case as using Angular, just put into NgOnInit.

let body = document.querySelector('.modal-open');
body.classList.remove('modal-open');
body.removeAttribute('style');
let divFromHell = document.querySelector('.modal-backdrop');
body.removeChild(divFromHell);

JRE executes the application but JVM reads the instructions line by line so it's interpreter.

You can alternatively use recv(x_bytes, socket.MSG_WAITALL), which seems to work only on Unix, and will return exactly x_bytes.

For people who have narrowed down the issue to the COMMENT ON statements (as per various answers below) and who have superuser access to the source database from which the dump file is created, the simplest solution might be to prevent the comments from being included to the dump file in the first place, by removing them from the source database being dumped...

COMMENT ON EXTENSION postgis IS NULL;
COMMENT ON EXTENSION plpgsql IS NULL;
COMMENT ON SCHEMA public IS NULL;

Future dumps then won't include the COMMENT ON statements.

The clone is a shallow copy of the array.

This test code prints:

[1, 2] / [1, 2]
[100, 200] / [100, 2]

because the MutableInteger is shared in both arrays as objects[0] and objects2[0], but you can change the reference objects[1] independently from objects2[1].

It's better to avoid unnecessary autoboxing for 2 reasons.

For one thing, it's a bit slower than int < int, as you're (sometimes) creating an extra object;

void doSomethingWith(Integer integerObject){ ...
  int i = 1000;
  doSomethingWith(i);//gets compiled into doSomethingWith(Integer.valueOf(i));

The bigger issue is that hidden autoboxing can hide exceptions:

void doSomethingWith (Integer count){
  if (count>0)  // gets compiled into count.intValue()>0

Calling this method with null will throw a NullPointerException.

The split between primitives and wrapper objects in java was always described as a kludge for speed. Autoboxing almost hides this, but not quite - it's cleaner just to keep track of the type. So if you've got an Integer object, you can just call compare() or intValue(), and if you've got the primitive just check the value directly.

\n is an escape sequence, denoted by the backslash. A normal forward slash, such as /n will not do the job. In your code you are using /n instead of \n.

function padToFour(number) {
  if (number<=9999) { number = ("000"+number).slice(-4); }
  return number;
}

Something like that?

Bonus incomprehensible-but-slicker single-line ES6 version:

let padToFour = number => number <= 9999 ? `000${number}`.slice(-4) : number;

ES6isms:

• let is a block scoped variable (as opposed to var’s functional scoping)
• => is an arrow function that among other things replaces function and is prepended by its parameters
• If a arrow function takes a single parameter you can omit the parentheses (hence number =>)
• If an arrow function body has a single line that starts with return you can omit the braces and the return keyword and simply use the expression
• To get the function body down to a single line I cheated and used a ternary expression

You need to take out the $ signs before the row numbers in the formula....and the row number used in the formula should correspond to the first row of data, so if you are applying this to the ("applies to") range $B$2:$B$5 it must be this formula

=$B2>$C2

by using that "relative" version rather than your "absolute" one Excel (implicitly) adjusts the formula for each row in the range, as if you were copying the formula down

Try imaskjs. It has Number, RegExp and other masks. Very simple to extend.

You can use >> to print in another file.

echo "hello" >> logfile.txt

This piece of code:

for s in ("fukushima", "123 is a number", ""):
    print s.ljust(20),  s[0].isdigit() if s else False

prints out the following:

fukushima            False
123 is a number      True
                     False

You can try like below

DECLARE @sqlCommand NVARCHAR(4000)
DECLARE @ID INT
DECLARE @Name NVARCHAR(100)
SET @ID = 4
SET @sqlCommand = 'SELECT @Name = [Name]
FROM [AdventureWorks2014].[HumanResources].[Department]
WHERE DepartmentID = @ID'
EXEC sp_executesql @sqlCommand, N'@ID INT, @Name NVARCHAR(100) OUTPUT',
@ID = @ID, @Name = @Name OUTPUT
SELECT @Name ReturnedName

I got around the issue by using a convert on the "?", so my code looks like convert(char(50),?) and that got rid of the truncation error.

You have a pointer to an object. Therefore, you need to access a field of an object that's pointed to by the pointer. To dereference the pointer you use *, and to access a field, you use ., so you can use:

cout << (*kwadrat).val1;

Note that the parentheses are necessary. This operation is common enough that long ago (when C was young) they decided to create a "shorthand" method of doing it:

cout << kwadrat->val1;

These are defined to be identical. As you can see, the -> basically just combines a * and a . into a single operation. If you were dealing directly with an object or a reference to an object, you'd be able to use the . without dereferencing a pointer first:

Kwadrat kwadrat2(2,3,4);

cout << kwadrat2.val1;

The :: is the scope resolution operator. It is used when you only need to qualify the name, but you're not dealing with an individual object at all. This would be primarily to access a static data member:

struct something { 
    static int x; // this only declares `something::x`. Often found in a header
};

int something::x;  // this defines `something::x`. Usually in .cpp/.cc/.C file.

In this case, since x is static, it's not associated with any particular instance of something. In fact, it will exist even if no instance of that type of object has been created. In this case, we can access it with the scope resolution operator:

something::x = 10;

std::cout << something::x;

Note, however, that it's also permitted to access a static member as if it was a member of a particular object:

something s;

s.x = 1;

At least if memory serves, early in the history of C++ this wasn't allowed, but the meaning is unambiguous, so they decided to allow it.

You can also initialise it like this:

struct name sara = { "Sara", "Black" };

Since (as a special case) you're allowed to initialise char arrays from string constants.

Now, as for what a struct actually is - it's a compound type composed of other values. What sara actually looks like in memory is a block of 20 consecutive char values (which can be referred to using sara.first, followed by 0 or more padding bytes, followed by another block of 20 consecutive char values (which can be referred to using sara.last). All other instances of the struct name type are laid out in the same way.

In this case, it is very unlikely that there is any padding, so a struct name is just a block of 40 characters, for which you have a name for the first 20 and the last 20.

You can find out how big a block of memory a struct name takes using sizeof(struct name), and you can find out where within that block of memory each member of the structure is placed at using offsetof(struct name, first) and offsetof(struct name, last).

1. Delete your project (DO NOT DELETE THE ORIGIN FILE IN THE FILE SYSTEM)
2. Right click at Package explorer area and right click import.
3. Go to Maven folder and hit import an existing maven project.

Hope it helps

Very easy:

   String manufacturer = Build.MANUFACTURER;
   String model = Build.MODEL;
   int version = Build.VERSION.SDK_INT;
   String versionRelease = Build.VERSION.RELEASE;

Log.e("MyActivity", "manufacturer " + manufacturer
            + " \n model " + model
            + " \n version " + version
            + " \n versionRelease " + versionRelease
    );

Output:

E/MyActivity:   manufacturer ManufacturerX
                model SM-T310 
                version 19 
                versionRelease 4.4.2

It sounds like you're not instantiating your class. That's the primary reason I get the "an object reference is required" error.

MyClass myClass = new MyClass();

once you've added that line you can then call your method

myClass.myMethod();

Also, are all of your classes in the same namespace? When I was first learning c# this was a common tripping point for me.
