My shell script calls the sql file and executes it. The spool output had the SQL query at the beginning followed by the query result.

This did not resolve my problem:

set echo off

This resolved my problem:

set verify off

Just await the three tasks separately, after starting them all.

var catTask = FeedCat();
var houseTask = SellHouse();
var carTask = BuyCar();

var cat = await catTask;
var house = await houseTask;
var car = await carTask;

When we use the ascii() it escapes the non-ascii characters and it doesn't change ascii characters correctly. So my main thought is, it doesn't change the ASCII characters, so I am iterating through the string and checking if the character is changed. If it changed then replacing it with the replacer, what you give.
For example: ' '(a single space) or '?' (with a question mark).

def remove(x, replacer):

     for i in x:
        if f"'{i}'" == ascii(i):
            pass
        else:
            x=x.replace(i,replacer)
     return x
remove('hái',' ')

Result: "h i" (with single space between).

Syntax : remove(str,non_ascii_replacer)
str = Here you will give the string you want to work with.
non_ascii_replacer = Here you will give the replacer which you want to replace all the non ASCII characters with.

The solution was to use getChildFragmentManager()

instead of getFragmentManager()

when calling from a fragment. If you are calling the method from an activity, then use getFragmentManager().

That will solve the problem.

Just one more alternative using URL

var theUrl = new URL(window.location.href);
theUrl.search = ""; //Remove any params
theUrl //as URL object
theUrl.href //as a string

The hash is used by dictionaries and sets to quickly look up the object. A good starting point is Wikipedia's article on hash tables.

Java does not support output parameters. You can use a return value, or pass in an object as a parameter and modify the object.

In Symfony 5 and in the common situation of a controller method use the injected Request object:

public function controllerFunction(Request $request, LoggerInterface $logger)
  ...
  $scheme = $request->getSchemeAndHttpHost();
  $logger->info('Domain is: ' . $scheme);
  ...
  //prepare to render
  $retarray = array(
    ...
    'scheme' => $scheme,
    ...
    );
  return $this->render('Template.html.twig', $retarray);
}

try $conn = mysql_connect("localhost", "root") or $conn = mysql_connect("localhost", "root", "")

Do try to give print (df.describe()) a shot. I hope it will be very helpful to get an overall description of your dataframe.

You've got a couple of issues here.

Firstly, you're defining your code within an anonymous function. This construct:

(function() {
  ...
)();

does two things. It defines an anonymous function and calls it. There are scope reasons to do this but I'm not sure it's what you actually want.

You're passing in a code block to setTimeout(). The problem is that update() is not within scope when executed like that. It however if you pass in a function pointer instead so this works:

(function() {
  $(document).ready(function() {update();});

  function update() { 
    $("#board").append(".");
    setTimeout(update, 1000);     }
  }
)();

because the function pointer update is within scope of that block.

But like I said, there is no need for the anonymous function so you can rewrite it like this:

$(document).ready(function() {update();});

function update() { 
  $("#board").append(".");
  setTimeout(update, 1000);     }
}

or

$(document).ready(function() {update();});

function update() { 
  $("#board").append(".");
  setTimeout('update()', 1000);     }
}

and both of these work. The second works because the update() within the code block is within scope now.

I also prefer the $(function() { ... } shortened block form and rather than calling setTimeout() within update() you can just use setInterval() instead:

$(function() {
  setInterval(update, 1000);
});

function update() {
  $("#board").append(".");
}

Hope that clears that up.

I'm late to the party but I encountered the same thing when I tried to get fancy and move my library and then had files being saved to a folder that was outdated:

.libloc <<- "C:/Program Files/rest_of_your_Library_FileName"

One other point to mention is that for Windows Computers, if you copy the address from Windows Explorer, you have to manually change the '\' to a '/' for the directory to be recognized.

The pip package you are looking for is tensorflow-tensorboard developed by Google.

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

Sub stituterangersNEW()
Dim t As Range
Dim x As Range
Dim dify As Boolean
Dim difx As Boolean
Dim time2 As Date
Dim time1 As Date

    'You said time1 doesn't change, so I left it in a singe cell.
    'If that is not correct, you will have to play with this some more.
    time1 = Range("A6").Value

    'Looping through each of our output cells.
    For Each t In Range("B7:E9") 'Change these to match your real ranges.

        'Looping through each departure date/time.
        '(Only one row in your example. This can be adjusted if needed.)
        For Each x In Range("B2:E2") 'Change these to match your real ranges.
            'Check to see if our dep time corresponds to
            'the matching column in our output
            If t.Column = x.Column Then
                'If it does, then check to see what our time value is
                If x > 0 Then
                    time2 = x.Value
                    'Apply the change to the output cell.
                    t.Value = time1 - time2
                    'Exit out of this loop and move to the next output cell.
                    Exit For
                End If
            End If
            'If the columns don't match, or the x value is not a time
            'then we'll move to the next dep time (x)
        Next x
    Next t

End Sub

EDIT

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

     A                      B                   C                   D                  E

Try to call your proc in this way:

DECLARE @UserIDout int

EXEC YOURPROC @EmailAddress = 'sdfds', @NickName = 'sdfdsfs', ..., @UserId = @UserIDout OUTPUT

SELECT @UserIDout 

Maybe you can use float:right;:

.one {_x000D_
  padding-left: 1em;_x000D_
  text-color: white;_x000D_
   display:inline; _x000D_

Using:

  SELECT t.ctn_no
    FROM YOUR_TABLE t
GROUP BY t.ctn_no
  HAVING COUNT(t.ctn_no) > 1

...will show you the ctn_no value(s) that have duplicates in your table. Adding criteria to the WHERE will allow you to further tune what duplicates there are:

  SELECT t.ctn_no
    FROM YOUR_TABLE t
   WHERE t.s_ind = 'Y'
GROUP BY t.ctn_no
  HAVING COUNT(t.ctn_no) > 1

If you want to see the other column values associated with the duplicate, you'll want to use a self join:

SELECT x.*
  FROM YOUR_TABLE x
  JOIN (SELECT t.ctn_no
          FROM YOUR_TABLE t
      GROUP BY t.ctn_no
        HAVING COUNT(t.ctn_no) > 1) y ON y.ctn_no = x.ctn_no

you must have read about function call . here i give you example of it.

<?php
 funtion pr($n)
{
echo $n;
 }
?>
<form action="<?php $f=$_POST['input'];pr($f);?>" method="POST">
<input name=input type=text></input>
</form>

Use the EXISTS key word for TRUE / FALSE return:

select exists(select 1 from contact where id=12)

Starting with node 8.0.0, you can use this:

const fs = require('fs');
const util = require('util');

const readdir = util.promisify(fs.readdir);

async function myF() {
  let names;
  try {
    names = await readdir('path/to/dir');
  } catch (err) {
    console.log(err);
  }
  if (names === undefined) {
    console.log('undefined');
  } else {
    console.log('First Name', names[0]);
  }
}

myF();

There are some SMTP servers that work without authentication, but if the server requires authentication, there is no way to circumvent that.

PHP's built-in mail functions are very limited - specifying the SMTP server is possible in WIndows only. On *nix, mail() will use the OS's binaries.

If you want to send E-Mail to an arbitrary SMTP server on the net, consider using a library like SwiftMailer. That will enable you to use, for example, Google Mail's outgoing servers.

If you want to bind an event like 'click' for all the elements having same class in the rendered DOM element then you can set up an event listener by using following parts of the code in components.ts file.

import { Component, OnInit, Renderer, ElementRef} from '@angular/core';

constructor( elementRef: ElementRef, renderer: Renderer) {
    dragulaService.drop.subscribe((value) => {
      this.onDrop(value.slice(1));
    });
}

public onDrop(args) {

  let [e, el] = args;

  this.toggleClassComTitle(e,'checked');

}


public toggleClassComTitle(el: any, name: string) {

    el.querySelectorAll('.com-item-title-anchor').forEach( function ( item ) {

      item.addEventListener('click', function(event) {
              console.log("item-clicked");

       });
    });

}

Your code is indeed using the normal way to create and delete a dynamic object. Yes, it's perfectly normal (and indeed guaranteed by the language standard!) that delete will call the object's destructor, just like new has to invoke the constructor.

If you weren't instantiating Object1 directly but some subclass thereof, I'd remind you that any class intended to be inherited from must have a virtual destructor (so that the correct subclass's destructor can be invoked in cases analogous to this one) -- but if your sample code is indeed representative of your actual code, this cannot be your current problem -- must be something else, maybe in the destructor code you're not showing us, or some heap-corruption in the code you're not showing within that function or the ones it calls...?

BTW, if you're always going to delete the object just before you exit the function which instantiates it, there's no point in making that object dynamic -- just declare it as a local (storage class auto, as is the default) variable of said function!

Seems you need to create user for your database and grant privileges for created user

--> create user for Data base

CREATE  USER <'username'>@'%'IDENTIFIED BY <'password'>;

ex - CREATE USER 'root'@'%'IDENTIFIED BY 'root';

--> Grant Privileges

FLUSH PRIVILEGES;
GRANT ALL PRIVILEGES ON <db name>.* TO '<username>'@'%';

ex- GRANT ALL PRIVILEGES ON mydb.* TO 'root'@'%';

I do not recall my original use case for this mechanism. Nowadays, I cannot think of any valid use case.

Your client should be able to detect when the connection is lost and allow you to re-create the connection. If it important that part of program logic is executed using the same connection, then use transactions.

tl;dr; Do not use this method.

A pragmatic solution is to force MySQL to keep the connection alive:

setInterval(function () {
    db.query('SELECT 1');
}, 5000);

I prefer this solution to connection pool and handling disconnect because it does not require to structure your code in a way thats aware of connection presence. Making a query every 5 seconds ensures that the connection will remain alive and PROTOCOL_CONNECTION_LOST does not occur.

Furthermore, this method ensures that you are keeping the same connection alive, as opposed to re-connecting. This is important. Consider what would happen if your script relied on LAST_INSERT_ID() and mysql connection have been reset without you being aware about it?

However, this only ensures that connection time out (wait_timeout and interactive_timeout) does not occur. It will fail, as expected, in all others scenarios. Therefore, make sure to handle other errors.

If it's a matter of just opening PDF to send some keys to it then why not try this

I am assuming that you have some pdf reader installed.

You can retrieve the format strings from the CultureInfo DateTimeFormat property, which is a DateTimeFormatInfo instance. This in turn has properties like ShortDatePattern and ShortTimePattern, containing the format strings:

CultureInfo us = new CultureInfo("en-US");
string shortUsDateFormatString = us.DateTimeFormat.ShortDatePattern;
string shortUsTimeFormatString = us.DateTimeFormat.ShortTimePattern;

CultureInfo uk = new CultureInfo("en-GB");
string shortUkDateFormatString = uk.DateTimeFormat.ShortDatePattern;
string shortUkTimeFormatString = uk.DateTimeFormat.ShortTimePattern;

If you simply want to format the date/time using the CultureInfo, pass it in as your IFormatter when converting the DateTime to a string, using the ToString method:

string us = myDate.ToString(new CultureInfo("en-US"));
string uk = myDate.ToString(new CultureInfo("en-GB"));

The problem obviously was (as you figured it out) that port 36250 wasn't open on the server side at the time you tried to connect (hence connection refused). I can see the server was supposed to open this socket after receiving SEND command on another connection, but it apparently was "not opening [it] up in sync with the client side".

Well, the main reason would be there was no synchronisation whatsoever. Calling:

cs.send("SEND " + FILE)
cs.close()

would just place the data into a OS buffer; close would probably flush the data and push into the network, but it would almost certainly return before the data would reach the server. Adding sleep after close might mitigate the problem, but this is not synchronisation.

The correct solution would be to make sure the server has opened the connection. This would require server sending you some message back (for example OK, or better PORT 36250 to indicate where to connect). This would make sure the server is already listening.

The other thing is you must check the return values of send to make sure how many bytes was taken from your buffer. Or use sendall.

(Sorry for disturbing with this late answer, but I found this to be a high traffic question and I really didn't like the sleep idea in the comments section.)

The important thing is one of the elements of calculation be a float-double type. Then to get a double result you need to cast this element like shown below:

c = static_cast<double>(a) / b;

or c = a / static_cast(b);

Or you can create it directly::

c = 7.0 / 3;

Note that one of elements of calculation must have the '.0' to indicate a division of a float-double type by an integer. Otherwise, despite the c variable be a double, the result will be zero too (an integer).

It's an unportable way to remove all data from the input buffer till the next newline. I've seen it used in cases like that:

char c;
char s[32];
puts("Type a char");
c=getchar();
fflush(stdin);
puts("Type a string");
fgets(s,32,stdin);

Without the fflush(), if you type a character, say "a", and the hit enter, the input buffer contains "a\n", the getchar() peeks the "a", but the "\n" remains in the buffer, so the next fgets() will find it and return an empty string without even waiting for user input.

However, note that this use of fflush() is unportable. I've tested right now on a Linux machine, and it does not work, for example.

use the --expression option

grep searchterm myfile.csv | sed --expression='s/replaceme/withthis/g'

NEQ is usually used for numbers and == is typically used for string comparison.

I cannot find any documentation that mentions a specific and equivalent inequality operand for string comparison (in place of NEQ). The solution using IF NOT == seems the most sound approach. I can't immediately think of a circumstance in which the evaluation of operations in a batch file would cause an issue or unexpected behavior when applying the IF NOT == comparison method to strings.

I wish I could offer insight into how the two functions behave differently on a lower level - would disassembling separate batch files (that use NEQ and IF NOT ==) offer any clues in terms of which (unofficially documented) native API calls conhost.exe is utilizing?

That's a good question, but I think you just misunderstand what you read.

Install PDO

The ./config --with-pdo-mysql is something you have to put on only if you compile your own PHP code. If you install it with package managers, you just have to use the command line given by Jany Hartikainen: sudo apt-get install php5-mysql and also sudo apt-get install pdo-mysql

Compatibility with mysql_

Apart from the fact mysql_ is really discouraged, they are both independent. If you use PDO mysql_ is not implicated, and if you use mysql_ PDO is not required.

If you turn off PDO without changing any line in your code, you won't have a problem. But since you started to connect and write queries with PDO, you have to keep it and give up mysql_.

Several years ago the MySQL team published a script to migrate to MySQLi. I don't know if it can be customised, but it's official.

i have tested that and it worked

val x = 9
def printType[T](x:T) :Unit = {println(x.getClass.toString())}

str_replace('"', "", $string);
str_replace("'", "", $string);

I assume you mean quotation marks?

Otherwise, go for some regex, this will work for html quotes for example:

preg_replace("/<!--.*?-->/", "", $string);

C-style quotes:

preg_replace("/\/\/.*?\n/", "\n", $string);

CSS-style quotes:

preg_replace("/\/*.*?\*\//", "", $string);

bash-style quotes:

preg-replace("/#.*?\n/", "\n", $string);

Etc etc...

You'll need the cookie plugin, which provides several additional signatures to the cookie function.

$.cookie('cookie_name', 'cookie_value') stores a transient cookie (only exists within this session's scope, while $.cookie('cookie_name', 'cookie_value', 'cookie_expiration") creates a cookie that will last across sessions - see http://www.stilbuero.de/2006/09/17/cookie-plugin-for-jquery/ for more information on the JQuery cookie plugin.

If you want to set cookies that are used for the entire site, you'll need to use JavaScript like this:

document.cookie = "name=value; expires=date; domain=domain; path=path; secure"

Designated initializes will be supported in c++2a, but you don't have to wait, because they are officialy supported by GCC, Clang and MSVC.

Update 20201

As @Code Doggo noted, anyone who is using Visual Studio 2019 will need to set /std:c++latest  for the "C++ Language Standard" field contained under Configuration Properties -> C/C++ -> Language.

Just look at the docs:

require_relative complements the builtin method require by allowing you to load a file that is relative to the file containing the require_relative statement.

For example, if you have unit test classes in the "test" directory, and data for them under the test "test/data" directory, then you might use a line like this in a test case:

require_relative "data/customer_data_1"

Same functionality i recently achieved using below function.

I wanted to enable SAVE button on edit.

1. Change event is NOT advisable as it will ONLY be fired if after editing, mouse is clicked somewhere else on the page before clicking SAVE button.
2. Key Press doesnt handle Backspace, Delete and Paste options.
3. Key Up handles everything including tab, Shift key.

Hence i wrote below function combining keypress, keyup (for backspace, delete) and paste event for text fields.

Hope it helps you.

function checkAnyFormFieldEdited() {
    /*
     * If any field is edited,then only it will enable Save button
     */
    $(':text').keypress(function(e) { // text written
        enableSaveBtn();
    });

    $(':text').keyup(function(e) {
        if (e.keyCode == 8 || e.keyCode == 46) { //backspace and delete key
            enableSaveBtn();
        } else { // rest ignore
            e.preventDefault();
        }
    });
    $(':text').bind('paste', function(e) { // text pasted
        enableSaveBtn();
    });

    $('select').change(function(e) { // select element changed
        enableSaveBtn();
    });

    $(':radio').change(function(e) { // radio changed
        enableSaveBtn();
    });

    $(':password').keypress(function(e) { // password written
        enableSaveBtn();
    });
    $(':password').bind('paste', function(e) { // password pasted
        enableSaveBtn();
    });


}

Your code is working just fine, you have to declare javscript method before DOM ready.

By all means, please use set() to create an empty set.

But, if you want to impress people, tell them that you can create an empty set using literals and * with Python >= 3.5 (see PEP 448) by doing:

>>> s = {*()}  # or {*{}} or {*[]}
>>> print(s)
set()

this is basically a more condensed way of doing {_ for _ in ()}, but, don't do this.

The most naive way would be to iterate over the String and make sure all the elements are valid digits for the given radix. This is about as efficient as it could possibly get, since you must look at each element at least once. I suppose we could micro-optimize it based on the radix, but for all intents and purposes this is as good as you can expect to get.

public static boolean isInteger(String s) {
    return isInteger(s,10);
}

public static boolean isInteger(String s, int radix) {
    if(s.isEmpty()) return false;
    for(int i = 0; i < s.length(); i++) {
        if(i == 0 && s.charAt(i) == '-') {
            if(s.length() == 1) return false;
            else continue;
        }
        if(Character.digit(s.charAt(i),radix) < 0) return false;
    }
    return true;
}

Alternatively, you can rely on the Java library to have this. It's not exception based, and will catch just about every error condition you can think of. It will be a little more expensive (you have to create a Scanner object, which in a critically-tight loop you don't want to do. But it generally shouldn't be too much more expensive, so for day-to-day operations it should be pretty reliable.

public static boolean isInteger(String s, int radix) {
    Scanner sc = new Scanner(s.trim());
    if(!sc.hasNextInt(radix)) return false;
    // we know it starts with a valid int, now make sure
    // there's nothing left!
    sc.nextInt(radix);
    return !sc.hasNext();
}

If best practices don't matter to you, or you want to troll the guy who does your code reviews, try this on for size:

public static boolean isInteger(String s) {
    try { 
        Integer.parseInt(s); 
    } catch(NumberFormatException e) { 
        return false; 
    } catch(NullPointerException e) {
        return false;
    }
    // only got here if we didn't return false
    return true;
}

Create the thread object inside the first for loop.

for (int i = 0; i < threads.length; i++) {
     threads[i] = new Thread(new Runnable() {
         public void run() {
             // some code to run in parallel
         }
     });
     threads[i].start();
 }

And then so what everyone here is saying.

for(i = 0; i < threads.length; i++)
  threads[i].join();

DATE_ADD works correctly. 1 January plus 6 months is 1 July, just like 1 January plus 1 month is 1 of February.

Between operation is inclusive. So, you are getting everything up to, and including, 1 July. (see also MySQL "between" clause not inclusive?)

What you need to do is subtract 1 day or use < operator instead of between.

You can do this with a string datatype. Use the PadLeft method:

var myString = "1";
myString = myString.PadLeft(myString.Length + 5, '0');

000001

If you want to add a sourceSet for testing in addition to all the existing ones, within a module regardless of the active flavor:

sourceSets {
    test {
        java.srcDirs += [
                'src/customDir/test/kotlin'
        ]
        print(java.srcDirs)   // Clean
    }
}

Pay attention to the operator += and if you want to run integration tests change test to androidTest.

There are a couple of good solutions here.

Similar to the answer from Harpal, but within the facet, so doesn't require any change to underlying data or pre-plotting manipulation:

# Change this code:
facet_grid(.~size) + 
# To this code:
facet_grid(~factor(size, levels=c('50%','100%','150%','200%')))

This is flexible, and can be implemented for any variable as you change what element is faceted, no underlying change in the data required.

If you don't feel like aliassing you can also just prefix the tablenames.

This way you can better automate generation of your queries. Also, it's a best-practice to not use select * (it is obviously slower than just selecting the fields you need Furthermore, only explicitly name the fields you want to have.

SELECT
    news.id, news.title, news.author, news.posted, 
    users.id, users.name, users.registered 
FROM 
    news 
LEFT JOIN 
    users 
ON 
    news.user = user.id

I had this problem just now and managed to figure out what it was. Was referencing a colour in my values that was causing problems. So defined it manually instead of using one from the dropdown suggestions.Then it worked!

Try this. It uses the split function which is a core part of javascript, nothing to do with jQuery.

var parts = html.split(":-"),
    i, l
;
for (i = 0, l = parts.length; i < l; i += 2) {
    $("#" + parts[i]).text(parts[i + 1]);
}

void is a reserved JavaScript keyword. It evaluates the expression and always returns undefined.

if you hit the "back" button it usually tends to stick, what you can do is when the form is submitted clear the element then before it goes to the next page but after doing with the element what you need to.

    $('#shares').keyup(function(){
                payment = 0;
                calcTotal();
                gtotal = ($('#shares').val() * 1) + payment;
                gtotal = gtotal.toFixed(2);
                $('#shares').val('');
                $("p.total").html("Total Payment: <strong>" + gtotal + "</strong>");
            });

You need to access the underlying buffer:

printf("%s\n", someString.c_str());

Or better use cout << someString << endl; (you need to #include <iostream> to use cout)

Additionally you might want to import the std namespace using using namespace std; or prefix both string and cout with std::.

CSV Files with Custom Delimiters

By default, a comma is used as a delimiter in a CSV file. However, some CSV files can use delimiters other than a comma. Few popular ones are | and \t.

import csv
data_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, delimiter='|')
    writer.writerows(data_list)

output:

SN|Name|Contribution
1|Linus Torvalds|Linux Kernel
2|Tim Berners-Lee|World Wide Web
3|Guido van Rossum|Python Programming

Write CSV files with quotes

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC, delimiter=';')
    writer.writerows(row_list) 

output:

"SN";"Name";"Contribution"
1;"Linus Torvalds";"Linux Kernel"
2;"Tim Berners-Lee";"World Wide Web"
3;"Guido van Rossum";"Python Programming"

As you can see, we have passed csv.QUOTE_NONNUMERIC to the quoting parameter. It is a constant defined by the csv module.

csv.QUOTE_NONNUMERIC specifies the writer object that quotes should be added around the non-numeric entries.

There are 3 other predefined constants you can pass to the quoting parameter:

• csv.QUOTE_ALL - Specifies the writer object to write CSV file with quotes around all the entries.
• csv.QUOTE_MINIMAL - Specifies the writer object to only quote those fields which contain special characters (delimiter, quotechar or any characters in lineterminator)
• csv.QUOTE_NONE - Specifies the writer object that none of the entries should be quoted. It is the default value.

import csv

row_list = [["SN", "Name", "Contribution"],
             [1, "Linus Torvalds", "Linux Kernel"],
             [2, "Tim Berners-Lee", "World Wide Web"],
             [3, "Guido van Rossum", "Python Programming"]]
with open('innovators.csv', 'w', newline='') as file:
    writer = csv.writer(file, quoting=csv.QUOTE_NONNUMERIC,
                        delimiter=';', quotechar='*')
    writer.writerows(row_list)

output:

*SN*;*Name*;*Contribution*
1;*Linus Torvalds*;*Linux Kernel*
2;*Tim Berners-Lee*;*World Wide Web*
3;*Guido van Rossum*;*Python Programming*

Here, we can see that quotechar='*' parameter instructs the writer object to use * as quote for all non-numeric values.

I also faced the same problem and tried almost everything possible from manually installing drivers to editing the winusb.inf file. But nothing worked for me.

Actually, the solution is quite simple. Its always there but we tend to miss it.

Prerequisites

Download the latest Android SDK and the latest drivers from here. Enable USB debugging and open Device Manager and keep it opened.

Steps

1) Connect your device and see if it is detected under "Android Devices" section. If it does, then its OK, otherwise, check the "Other devices" section and install the driver manually.

2) Be sure to check "Android Composite ADB Interface". This is the interface Android needs for ADB to work.

3) Go to "[SDK]/platform-tools", Shift-click there and open Command Prompt and type "adb devices" and see if your device is listed there with an unique ID.

4) If yes, then ADB have been successfully detected at this point. Next, write "adb reboot bootloader" to open the bootloader. At this point check Device Manager under "Android Devices", you will find "Android Bootlaoder Interface". Its not much important to us actually.

5) Next, using the volume down keys, move to "Recovery Mode".

6) THIS IS IMPORTANT - At this point, check the Device Manger under "Android Devices". If you do not see anything under this section or this section at all, then we need to manually install it.

7) Check the "Other devices" section and find your device listed there. Right click -> Update drivers -"Browse my computer..." -> "Let me pick from a list..." and select "ADB Composite Interface".

8) Now you can see your device listed under "Android Devices" even inside the Recovery.

9) Write "adb devices" at this point and you will see your device listed with the same ID.

10) Now, just write "adb sideload [update].zip" and your are done.

Hope this helps.

Starting Python 3.8, the standard library provides the NormalDist object as part of the statistics module.

It can be used to get the probability density function (pdf - likelihood that a random sample X will be near the given value x) for a given mean (mu) and standard deviation (sigma):

from statistics import NormalDist

NormalDist(mu=100, sigma=12).pdf(98)
# 0.032786643008494994

Also note that the NormalDist object also provides the cumulative distribution function (cdf - probability that a random sample X will be less than or equal to x):

NormalDist(mu=100, sigma=12).cdf(98)
# 0.43381616738909634

private static final int SELECT_PHOTO = 100;

Start intent

Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);    

Process result

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 

    switch(requestCode) { 
    case SELECT_PHOTO:
        if(resultCode == RESULT_OK){  
            Uri selectedImage = imageReturnedIntent.getData();
            InputStream imageStream = getContentResolver().openInputStream(selectedImage);
            Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
        }
    }
}

Alternatively, you can also downsample your image to avoid OutOfMemory errors.

private Bitmap decodeUri(Uri selectedImage) throws FileNotFoundException {

        // Decode image size
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o);

        // The new size we want to scale to
        final int REQUIRED_SIZE = 140;

        // Find the correct scale value. It should be the power of 2.
        int width_tmp = o.outWidth, height_tmp = o.outHeight;
        int scale = 1;
        while (true) {
            if (width_tmp / 2 < REQUIRED_SIZE
               || height_tmp / 2 < REQUIRED_SIZE) {
                break;
            }
            width_tmp /= 2;
            height_tmp /= 2;
            scale *= 2;
        }

        // Decode with inSampleSize
        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o2);

    }

<input type='submit' value='Submit' onclick='this.form.action="somethingelse";' />

Or you can modify it from outside the form, with javascript the normal way:

 document.getElementById('form_id').action = 'somethingelse';

Here is your article for doing it with code

private void Form1_Load(object sender, System.EventArgs e)
{
     // Create the ToolTip and associate with the Form container.
     ToolTip toolTip1 = new ToolTip();

     // Set up the delays for the ToolTip.
     toolTip1.AutoPopDelay = 5000;
     toolTip1.InitialDelay = 1000;
     toolTip1.ReshowDelay = 500;
     // Force the ToolTip text to be displayed whether or not the form is active.
     toolTip1.ShowAlways = true;

     // Set up the ToolTip text for the Button and Checkbox.
     toolTip1.SetToolTip(this.button1, "My button1");
     toolTip1.SetToolTip(this.checkBox1, "My checkBox1");
}

You could use cut

 df$valueBin <- cut(df$value, c(-Inf, 250, 500, 1000, 2000, Inf), 
    labels=c('<=250', '250-500', '500-1,000', '1,000-2,000', '>2,000'))

data

 set.seed(24)
 df <- data.frame(value= sample(0:2500, 100, replace=TRUE))

Microsoft Docs gives us two approaches.

Recommended HttpPost Edit code: Read and update

This is the same old way we used to do in previous versions of Entity Framework. and this is what Microsoft recommends for us.

Advantages

• Prevents overposting
• EFs automatic change tracking sets the Modified flag on the fields that are changed by form input.

Alternative HttpPost Edit code: Create and attach

an alternative is to attach an entity created by the model binder to the EF context and mark it as modified.

As mentioned in the other answer the read-first approach requires an extra database read, and can result in more complex code for handling concurrency conflicts.

I can't understand why this JAXB IllegalAnnotationException is thrown

I also was getting the ### counts of IllegalAnnotationExceptions exception and it seemed to be due to an improper dependency hierarchy in my Spring wiring.

I figured it out by putting a breakpoint in the JAXB code when it does the throw. For me this was at com.sun.xml.bind.v2.runtime.IllegalAnnotationsException$Builder.check(). Then I dumped the list variable which gives something like:

[org.mortbay.jetty.Handler is an interface, and JAXB can't handle interfaces.
this problem is related to the following location:
    at org.mortbay.jetty.Handler
    at public org.mortbay.jetty.Handler[] org.mortbay.jetty.handler.HandlerCollection.getHandlers()
    at org.mortbay.jetty.handler.HandlerCollection
    at org.mortbay.jetty.handler.ContextHandlerCollection
    at com.mprew.ec2.commons.server.LocalContextHandlerCollection
    at private com.mprew.ec2.commons.server.LocalContextHandlerCollection com.mprew.ec2.commons.services.jaxws_asm.SetLocalContextHandlerCollection.arg0
    at com.mprew.ec2.commons.services.jaxws_asm.SetLocalContextHandlerCollection,
org.mortbay.jetty.Handler does not have a no-arg default constructor.]
....

The does not have a no-arg default constructor seemed to me to be misleading. Maybe I wasn't understanding what the exception was saying. But it did indicate that there was a problem with my LocalContextHandlerCollection. I removed a dependency loop and the error cleared.

Hopefully this will be helpful to others.

DateTime TaskStart = DateTime.Parse(dr["TaskStart"].ToString());

• To undo once: C-/
• To undo twice: C-/ C-/

• To redo once, immediately after undoing: C-g C-/
• To redo twice, immediately after undoing: C-g C-/ C-/. Note that C-g is not repeated.

• To undo immediately again, once: C-g C-/
• To undo immediately again, twice: C-g C-/ C-/

• To redo again, the same…

If you have pressed any keys (whether typing characters or just moving the cursor) since your last undo command, there is no need to type C-g before your next undo/redo. C-g is just a safe key to hit that does nothing on its own, but counts as a non-undo key to signal the end of your undo sequence. Pressing another command such as C-f would work too; it’s just that it would move the cursor from where you had it.

If you hit C-g or another command when you didn’t mean to, and you are now undoing in the wrong direction, simply hit C-g to reverse your direction again. You will have to undo all the way through your accidental redos and undos before you get to the undos you want, but if you just keep hitting C-/, you will eventually reach the state you want. In fact, every state the buffer has ever been in is reachable, if you hit C-g once and then press C-/ enough times.

Alternative shortcuts for undo, other than C-/, are C-_, C-x u, and M-x undo.

See Undo in the Emacs Manual for more details on Emacs’s undo system.

There are two common approaches for this:

• Specify http-proxy- options in your /etc/.subversion/servers or %APPDATA%\Subversion\servers file,

• Use --config-option command-line option to specify the same http-proxy- options in single command-line you run. For example,

  svn checkout ^
  --config-option servers:global:http-proxy-host=<PROXY-HOST> ^
  --config-option servers:global:http-proxy-port=<PORT> <REPO-URL> <LWC-DIR> 
  

If you are on Windows, you can also write http-proxy- options to Windows Registry. It's pretty handy if you need to apply proxy settings in Active Directory environment via Group Policy Objects.

For those coming across this and looking for performance, it looks like #delete and #tr are about the same in speed and 2-4x faster than gsub.

text = "Here is a string with / some forwa/rd slashes"
tr = Benchmark.measure { 10000.times { text.tr('/', '') } }
# tr.total => 0.01
delete = Benchmark.measure { 10000.times { text.delete('/') } }
# delete.total => 0.01
gsub = Benchmark.measure { 10000.times { text.gsub('/', '') } }
# gsub.total => 0.02 - 0.04

You can convert type of plaintext to string:

f.write(str(plaintext) + '\n')

new ModelAndView("welcomePage", "WelcomeMessage", message);

is shorthand for

ModelAndView mav = new ModelAndView();
mav.setViewName("welcomePage");
mav.addObject("WelcomeMessage", message);

Looking at the code above, you can see the view name is "welcomePage". Your ViewResolver (usually setup in .../WEB-INF/spring-servlet.xml) will translate this into a View. The last line of the code sets an attribute in your model (addObject("WelcomeMessage", message)). That's where the model comes into play.

tar -cf my_archive `find ./ | grep '.php\|.html'`

Use "find" and "grep" to get all path of .php and .html files in all directory and its sub-directories. Then pass those path information to tar to compress.

Please be careful with those symbol ` and '. Note also that this will hit the limit of how many characters your shell will allow on the command line, unlike some of the other answers.

Also, if u want to find all indexes of a String in a String.

int index = word.indexOf(guess);
while (index >= 0) {
    System.out.println(index);
    index = word.indexOf(guess, index + guess.length());
}

I think performance wise this is by far the fastest:

var t = 34236; // your seconds
var time = ('0'+Math.floor(t/3600) % 24).slice(-2)+':'+('0'+Math.floor(t/60)%60).slice(-2)+':'+('0' + t % 60).slice(-2)
//would output: 09:30:36

If you happen to be using the Ruby gem redcarpet to render Markdown, you may still have this problem.

You can escape the numbering, and redcarpet will happily ignore any special meaning:

1\. Some heading

text text
text text

text text

2\. Some other heading

blah blah

more blah blah

First of all, never use a for in loop to enumerate over an array. Never. Use good old for(var i = 0; i<arr.length; i++).

The reason behind this is the following: each object in JavaScript has a special field called prototype. Everything you add to that field is going to be accessible on every object of that type. Suppose you want all arrays to have a cool new function called filter_0 that will filter zeroes out.

Array.prototype.filter_0 = function() {
    var res = [];
    for (var i = 0; i < this.length; i++) {
        if (this[i] != 0) {
            res.push(this[i]);
        }
    }
    return res;
};

console.log([0, 5, 0, 3, 0, 1, 0].filter_0());
//prints [5,3,1]

This is a standard way to extend objects and add new methods. Lots of libraries do this. However, let's look at how for in works now:

var listeners = ["a", "b", "c"];
for (o in listeners) {
    console.log(o);
}
//prints:
//  0
//  1
//  2
//  filter_0

Do you see? It suddenly thinks filter_0 is another array index. Of course, it is not really a numeric index, but for in enumerates through object fields, not just numeric indexes. So we're now enumerating through every numeric index and filter_0. But filter_0 is not a field of any particular array object, every array object has this property now.

Luckily, all objects have a hasOwnProperty method, which checks if this field really belongs to the object itself or if it is simply inherited from the prototype chain and thus belongs to all the objects of that type.

for (o in listeners) {
    if (listeners.hasOwnProperty(o)) {
       console.log(o);
    }
}
 //prints:
 //  0
 //  1
 //  2

Note, that although this code works as expected for arrays, you should never, never, use for in and for each in for arrays. Remember that for in enumerates the fields of an object, not array indexes or values.

var listeners = ["a", "b", "c"];
listeners.happy = "Happy debugging";

for (o in listeners) {
    if (listeners.hasOwnProperty(o)) {
       console.log(o);
    }
}

 //prints:
 //  0
 //  1
 //  2
 //  happy

I made a method to do this below called jsonArrayToObjectList. Its a handy static class that will take a filename and the file contains an array in JSON form.

 List<Items> items = jsonArrayToObjectList(
            "domain/ItemsArray.json",  Item.class);

    public static <T> List<T> jsonArrayToObjectList(String jsonFileName, Class<T> tClass) throws IOException {
        ObjectMapper mapper = new ObjectMapper();
        final File file = ResourceUtils.getFile("classpath:" + jsonFileName);
        CollectionType listType = mapper.getTypeFactory()
            .constructCollectionType(ArrayList.class, tClass);
        List<T> ts = mapper.readValue(file, listType);
        return ts;
    }

Global variables and static variables are automatically initialized to zero. If you have simply

char ZEROARRAY[1024];

at global scope it will be all zeros at runtime. But actually there is a shorthand syntax if you had a local array. If an array is partially initialized, elements that are not initialized receive the value 0 of the appropriate type. You could write:

char ZEROARRAY[1024] = {0};

The compiler would fill the unwritten entries with zeros. Alternatively you could use memset to initialize the array at program startup:

memset(ZEROARRAY, 0, 1024);

That would be useful if you had changed it and wanted to reset it back to all zeros.

You shall pass a this pointer to tell the function which object to work on because it relies on that as opposed to a static member function.

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

you can use HashMap<String, List<Integer>> to merge both hashmaps and avoid losing elements paired with the same key.

HashMap<String, Integer> map1 = new HashMap<>();
HashMap<String, Integer> map2 = new HashMap<>();
map1.put("key1", 1);
map1.put("key2", 2);
map1.put("key3", 3);
map2.put("key1", 4);
map2.put("key2", 5);
map2.put("key3", 6);
HashMap<String, List<Integer>> map3 = new HashMap<>();
map1.forEach((str, num) -> map3.put(str, new ArrayList<>(Arrays.asList(num))));
//checking for each key if its already in the map, and if so, you just add the integer to the list paired with this key
for (Map.Entry<String, Integer> entry : map2.entrySet()) {
    Integer value = entry.getValue();
    String key = entry.getKey();
    if (map3.containsKey(key)) {
        map3.get(key).add(value);
    } else {
        map3.put(key, new ArrayList<>(Arrays.asList(value)));
    }
}
map3.forEach((str, list) -> System.out.println("{" + str + ": " + list + "}"));

output:

{key1: [1, 4]}
{key2: [2, 5]}
{key3: [3, 6]}

Try this:

ul li a:after {
    display: block;
    content: "";
    width: 3px;
    height: 5px;
    background: transparent url('../images/small_triangle.png') no-repeat;
}

You need the content: ""; declaration to give your generated element content, even if that content is "nothing".

Also, I fixed the syntax/ordering of your background declaration.

My solution for rounding specific corners of UIView and UITextFiels in swift is to use

.layer.cornerRadius

and

layer.maskedCorners

of actual UIView or UITextFields.

Example:

fileprivate func inputTextFieldStyle() {
        inputTextField.layer.masksToBounds = true
        inputTextField.layer.borderWidth = 1
        inputTextField.layer.cornerRadius = 25
        inputTextField.layer.maskedCorners = [.layerMaxXMaxYCorner,.layerMaxXMinYCorner]
        inputTextField.layer.borderColor = UIColor.white.cgColor
    }

And by using

.layerMaxXMaxYCorner

and

.layerMaxXMinYCorner

, I can specify top right and bottom right corner of the UITextField to be rounded.

You can see the result here:

to search every column of every table for a particular value

This does not define how to match exactly.
Nor does it define what to return exactly.

Assuming:

• Find any row with any column containing the given value in its text representation - as opposed to equaling the given value.
• Return the table name (regclass) and the tuple ID (ctid), because that's simplest.

Here is a dead simple, fast and slightly dirty way:

CREATE OR REPLACE FUNCTION search_whole_db(_like_pattern text)
  RETURNS TABLE(_tbl regclass, _ctid tid) AS
$func$
BEGIN
   FOR _tbl IN
      SELECT c.oid::regclass
      FROM   pg_class c
      JOIN   pg_namespace n ON n.oid = relnamespace
      WHERE  c.relkind = 'r'                           -- only tables
      AND    n.nspname !~ '^(pg_|information_schema)'  -- exclude system schemas
      ORDER BY n.nspname, c.relname
   LOOP
      RETURN QUERY EXECUTE format(
         'SELECT $1, ctid FROM %s t WHERE t::text ~~ %L'
       , _tbl, '%' || _like_pattern || '%')
      USING _tbl;
   END LOOP;
END
$func$  LANGUAGE plpgsql;

Call:

SELECT * FROM search_whole_db('mypattern');

Provide the search pattern without enclosing %.

Why slightly dirty?

If separators and decorators for the row in text representation can be part of the search pattern, there can be false positives:

• column separator: , by default
• whole row is enclosed in parentheses:()
• some values are enclosed in double quotes "
• \ may be added as escape char

And the text representation of some columns may depend on local settings - but that ambiguity is inherent to the question, not to my solution.

Each qualifying row is returned once only, even when it matches multiple times (as opposed to other answers here).

This searches the whole DB except for system catalogs. Will typically take a long time to finish. You might want to restrict to certain schemas / tables (or even columns) like demonstrated in other answers. Or add notices and a progress indicator, also demonstrated in another answer.

The regclass object identifier type is represented as table name, schema-qualified where necessary to disambiguate according to the current search_path:

• Find the referenced table name using table, field and schema name

What is the ctid?

• How do I decompose ctid into page and row numbers?

You might want to escape characters with special meaning in the search pattern. See:

• Escape function for regular expression or LIKE patterns

For arrays you can use: Array.FindIndex<T>:

int keyIndex = Array.FindIndex(words, w => w.IsKey);

For lists you can use List<T>.FindIndex:

int keyIndex = words.FindIndex(w => w.IsKey);

You can also write a generic extension method that works for any Enumerable<T>:

///<summary>Finds the index of the first item matching an expression in an enumerable.</summary>
///<param name="items">The enumerable to search.</param>
///<param name="predicate">The expression to test the items against.</param>
///<returns>The index of the first matching item, or -1 if no items match.</returns>
public static int FindIndex<T>(this IEnumerable<T> items, Func<T, bool> predicate) {
    if (items == null) throw new ArgumentNullException("items");
    if (predicate == null) throw new ArgumentNullException("predicate");

    int retVal = 0;
    foreach (var item in items) {
        if (predicate(item)) return retVal;
        retVal++;
    }
    return -1;
}

And you can use LINQ as well:

int keyIndex = words
    .Select((v, i) => new {Word = v, Index = i})
    .FirstOrDefault(x => x.Word.IsKey)?.Index ?? -1;

But it would be possible if one were used in place of the variable in @html.Hidden field. As in this example.

@Html.Hidden("myVar", 0);

set the field per script:

<script>
function setMyValue(value) {
     $('#myVar').val(value);       
}
</script>

I hope I can at least offer no small Workaround.

Get requests should not have content-type because they do not have request entity (that is, a body)

To get the maximum value of a column across a set of rows:

SELECT MAX(column1) FROM table; -- expect one result

To get the maximum value of a set of columns, literals, or variables for each row:

SELECT GREATEST(column1, 1, 0, @val) FROM table; -- expect many results

This is a tricky question.

There a set of problems about file permissions. If you can do this at the command line

$ sudo chown myaccount /path/to/file

then you have a standard permissions problem. Make sure you own the file and have permission to modify the directory.

If you cannnot get permissions, then you have probably mounted a FAT-32 filesystem. If you ls -l the file, and you find it is owned by root and a member of the "plugdev" group, then you are certain its the issue. FAT-32 permissions are set at the time of mounting, using the line of /etc/fstab file. You can set the uid/gid of all the files like this:

UUID=C14C-CE25  /big            vfat    utf8,umask=007,uid=1000,gid=1000 0       1

Also, note that the FAT-32 won't take symbolic links.

Wrote the whole thing up at http://www.charlesmerriam.com/blog/2009/12/operation-not-permitted-and-the-fat-32-system/

In the $routeProvider URI patters, you can specify variable parameters, like so: $routeProvider.when('/page/:pageNumber' ... , and access it in your controller via $routeParams.

There is a good example at the end of the $route page: http://docs.angularjs.org/api/ng.$route

EDIT (for the edited question):

The routing system is unfortunately very limited - there is a lot of discussion on this topic, and some solutions have been proposed, namely via creating multiple named views, etc.. But right now, the ngView directive serves only ONE view per route, on a one-to-one basis. You can go about this in multiple ways - the simpler one would be to use the view's template as a loader, with a <ng-include src="myTemplateUrl"></ng-include> tag in it ($scope.myTemplateUrl would be created in the controller).

I use a more complex (but cleaner, for larger and more complicated problems) solution, basically skipping the $route service altogether, that is detailed here:

http://www.bennadel.com/blog/2420-Mapping-AngularJS-Routes-Onto-URL-Parameters-And-Client-Side-Events.htm

The following code worked for me:

public vidOff() {

      let stream = this.video.nativeElement.srcObject;
      let tracks = stream.getTracks();

      tracks.forEach(function (track) {
          track.stop();
      });

      this.video.nativeElement.srcObject = null;
      this.video.nativeElement.stop();
  }

Try Parallel for longer lists:

Parallel.ForEach(li.Where(f => f.name == "di"), l => l.age = 10);

A good example where to subscribe a setInterval(), and use a clearInterval() to stop the forever loop:

function myTimer() {

}

var timer = setInterval(myTimer, 5000);

call this line to stop the loop:

clearInterval(timer);

You can return an object of a Class in Java.

If you are returning more than 1 value that are related, then it makes sense to encapsulate them into a class and then return an object of that class.

If you want to return unrelated values, then you can use Java's built-in container classes like Map, List, Set etc. Check the java.util package's JavaDoc for more details.

Can someone help me with the exact syntax?

It's a three-step process, and it involves modifying the openssl.cnf file. You might be able to do it with only command line options, but I don't do it that way.

Find your openssl.cnf file. It is likely located in /usr/lib/ssl/openssl.cnf:

$ find /usr/lib -name openssl.cnf
/usr/lib/openssl.cnf
/usr/lib/openssh/openssl.cnf
/usr/lib/ssl/openssl.cnf

On my Debian system, /usr/lib/ssl/openssl.cnf is used by the built-in openssl program. On recent Debian systems it is located at /etc/ssl/openssl.cnf

You can determine which openssl.cnf is being used by adding a spurious XXX to the file and see if openssl chokes.

First, modify the req parameters. Add an alternate_names section to openssl.cnf with the names you want to use. There are no existing alternate_names sections, so it does not matter where you add it.

[ alternate_names ]

DNS.1        = example.com
DNS.2        = www.example.com
DNS.3        = mail.example.com
DNS.4        = ftp.example.com

Next, add the following to the existing [ v3_ca ] section. Search for the exact string [ v3_ca ]:

subjectAltName      = @alternate_names

You might change keyUsage to the following under [ v3_ca ]:

keyUsage = digitalSignature, keyEncipherment

digitalSignature and keyEncipherment are standard fare for a server certificate. Don't worry about nonRepudiation. It's a useless bit thought up by computer science guys/gals who wanted to be lawyers. It means nothing in the legal world.

In the end, the IETF (RFC 5280), browsers and CAs run fast and loose, so it probably does not matter what key usage you provide.

Second, modify the signing parameters. Find this line under the CA_default section:

# Extension copying option: use with caution.
# copy_extensions = copy

And change it to:

# Extension copying option: use with caution.
copy_extensions = copy

This ensures the SANs are copied into the certificate. The other ways to copy the DNS names are broken.

Third, generate your self-signed certificate:

$ openssl genrsa -out private.key 3072
$ openssl req -new -x509 -key private.key -sha256 -out certificate.pem -days 730
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
...

Finally, examine the certificate:

$ openssl x509 -in certificate.pem -text -noout

Yes. In fact Axel Schreiner provides his book "Object-oriented Programming in ANSI-C" for free which covers the subject quite thoroughly.

The most efficient way is to take input make the logic and run

so the code is like this to make your own space maker

need = input("Write a string:- ")
result = ''
for character in need:
   result = result + character + ' '
print(result)    # to rid of space after O

but if you want to use what python give then use this code

need2 = input("Write a string:- ")

print(" ".join(need2))

If you want to use Apple’s system install of Python 2.7, be aware that it doesn’t quite follow the naming standards laid out in PEP 394.

In particular, it includes the optional symlinks with suffix 2.7 that you’re told not to rely on, and does not include the recommended symlinks with suffix 2 that you’re told you should rely on.

If you want to fix this, while sticking with Apple’s Python, you can create your own symlinks:

$ cd <somewhere writable and in your PATH>
$ ln -s /usr/bin/python python2

Or aliases in your bash config:

alias python2 python2.7

And you can do likewise for Apple’s 2to3, easy_install, etc. if you need them.

You shouldn’t try to put these symlinks into /usr/bin, and definitely don’t try to rename what’s already there, or to change the distutils setup to something more PEP-compliant. Those files are all part of the OS, and can be used by other parts of the OS, and your changes can be overwritten on even a minor update from 10.13.5 to 10.13.6 or something, so leave them alone and work around them as described above.

Alternatively, you could:

• Just use python2.7 instead of python2 on the command line and in your shbangs and so on.
• Use virtual environments or conda environments. The global python, python3, python2, etc. don’t matter when you’re always using the activated environment’s local python.
• Stop using Apple’s 2.7 and instead install a whole other 2.7 alongside it, as most of the other answers suggest. (I don’t know why so many of them are also suggesting that you install a second 3.6. That’s just going to add even more confusion, for no benefit.)

The default install location is /usr/local, so add this to your ~/.bash_profile file:

export PATH=$PATH:/usr/local/git/bin/

Then run source ~/.bash_profile in Terminal.

I tried everything here, somehow deleting all the bin and obj folders in my project didn't work. Releasing the folders from other processes did nothing. Restarting did nothing. Removing read only from every file by unchecking it on the main folder didn't help.

Every dependency ended up adding themselves to the problem. Building directly in the dependencies' folder worked so I was confused. I was going to duplicate this question but I found something that worked.

You know what worked?

dotnet clean

For pre 1.1 django it is simple (for default admin site instance):

reverse('admin_%s_%s_change' % (app_label, model_name), args=(object_id,))

Try this:

<?php
    $str = "This is some <b>bold</b> text.";
    echo htmlspecialchars($str);
?>

merged = map(names(first), ~c(first[[.x]], second[[.x]])
merged = set_names(merged, names(first))

Using purrr. Also solves the problem of your lists not being in order.

I also faced the same issue, now it is resolved. If you are facing issues with pure components or classes, make sure that you are using .js extension instead of .jsx.

Remove punctuaion(It will remove . as well as part of punctuation handling using below code)

        text_string = text_string.translate(tbl) #text_string don't have punctuation
        w = word_tokenize(text_string)  #now tokenize the string

The reason for using dictionaries in the first place is performance. Although it is correct that you can use named vectors and lists for the task the issue is that they are becoming quite slow and memory hungry with more data.

Yet what many people don't know is that R has indeed an inbuilt dictionary data structure: environments with the option hash = TRUE

See the following example for how to make it work:

# vectorize assign, get and exists for convenience
assign_hash <- Vectorize(assign, vectorize.args = c("x", "value"))
get_hash <- Vectorize(get, vectorize.args = "x")
exists_hash <- Vectorize(exists, vectorize.args = "x")

# keys and values
key<- c("tic", "tac", "toe")
value <- c(1, 22, 333)

# initialize hash
hash = new.env(hash = TRUE, parent = emptyenv(), size = 100L)
# assign values to keys
assign_hash(key, value, hash)
## tic tac toe 
##   1  22 333
# get values for keys
get_hash(c("toe", "tic"), hash)
## toe tic 
## 333   1
# alternatively:
mget(c("toe", "tic"), hash)
## $toe
## [1] 333
## 
## $tic
## [1] 1
# show all keys
ls(hash)
## [1] "tac" "tic" "toe"
# show all keys with values
get_hash(ls(hash), hash)
## tac tic toe 
##  22   1 333
# remove key-value pairs
rm(list = c("toe", "tic"), envir = hash)
get_hash(ls(hash), hash)
## tac 
##  22
# check if keys are in hash
exists_hash(c("tac", "nothere"), hash)
##     tac nothere 
##    TRUE   FALSE
# for single keys this is also possible:
# show value for single key
hash[["tac"]]
## [1] 22
# create new key-value pair
hash[["test"]] <- 1234
get_hash(ls(hash), hash)
##  tac test 
##   22 1234
# update single value
hash[["test"]] <- 54321
get_hash(ls(hash), hash)
##   tac  test 
##    22 54321

Edit: On the basis of this answer I wrote a blog post with some more context: http://blog.ephorie.de/hash-me-if-you-can

Here is the solution that I used for installing a site's public cert into the systems keystore for use.

Download the certificate with the following command:

unix, linux, mac

openssl s_client -connect [host]:[port|443] < /dev/null | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > [host].crt

windows

openssl s_client -connect [host]:[port|443] < NUL | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > [host].crt

That will create a crt that can be used to import into a keystore.

Install the new certificate with the command:

keytool -import -alias "[host]" -keystore [path to keystore] -file [host].crt

This will allow you to import the new cert from the site that is causing the exception.

No, and your compiler already gave you a comprehensive explanation.

But you could do this:

constexpr char constString[] = "constString";

At runtime, this can be used to construct a std::string when needed.

@Mark Schäfer

Never too late, but add a slash (/) after static:

spring.resources.static-locations=file:/opt/x/y/z/static/

So http://<host>/index.html is now reachable.

Pawel Sawicz .NET blog has a real good explanation and example code, explaining how to call the library;

GET:

var client = new RestClient("192.168.0.1");
var request = new RestRequest("api/item/", Method.GET);
var queryResult = client.Execute<List<Items>>(request).Data;

POST:

var client = new RestClient("http://192.168.0.1");
var request = new RestRequest("api/item/", Method.POST);
request.RequestFormat = DataFormat.Json;
request.AddBody(new Item
{
   ItemName = someName,
   Price = 19.99
});
client.Execute(request);

DELETE:

var item = new Item(){//body};
var client = new RestClient("http://192.168.0.1");
var request = new RestRequest("api/item/{id}", Method.DELETE);
request.AddParameter("id", idItem);
 
client.Execute(request)

The RestSharp GitHub page has quite an exhaustive sample halfway down the page. To get started install the RestSharp NuGet package in your project, then include the necessary namespace references in your code, then above code should work (possibly negating your need for a full example application).

For no errors.

error_reporting(0);

or for just not strict

error_reporting(E_ALL ^ E_STRICT);

and if you ever want to display all errors again, use

error_reporting(-1);

its very true on oracle as well as sql is "users" is a reserved words just change it , it will serve u the best if u like change it to this

UPDATE system_info set field_value = 'NewValue' 

FROM system_users users JOIN system_info info ON users.role_type = info.field_desc where users.user_name = 'uname'

My tested version

Sub PrintArray(RowPrint, ColPrint, ArrayName, WorkSheetName)

Sheets(WorkSheetName).Range(Cells(RowPrint, ColPrint), _
Cells(RowPrint + UBound(ArrayName, 2) - 1, _
ColPrint + UBound(ArrayName, 1) - 1)) = _
WorksheetFunction.Transpose(ArrayName)

End Sub

Or you can use one SQL-command instead of create and call stored procedure

INSERT INTO [order_cart](orId,caId)
OUTPUT inserted.*
SELECT
   (SELECT MAX(orId) FROM [order]) as orId,
   (SELECT MAX(caId) FROM [cart]) as caId;

You might also consider Microsoft Enterprise Library Logging Block. It comes with nice designer.

On Mac OS X Terminal, this functionality is already built in to the Terminal Application as menu View ? Clear Scrollback (the default is CMD + K).

So you can re-assign this as you like with Apple's Keyboard shortcuts. Just add a new shortcut for Terminal with the command "Clear Scrollback". (I use CMD + L, because it's similar to Ctrl + L to clear the current screen contents, without clearing the buffer.)

I am not sure how you would use this in a script (maybe AppleScript as others have pointed out).

The clearest answer. Does “X& const x” make any sense?

No, it is nonsense

To find out what the above declaration means, read it right-to-left: “x is a const reference to a X”. But that is redundant — references are always const, in the sense that you can never reseat a reference to make it refer to a different object. Never. With or without the const.

In other words, “X& const x” is functionally equivalent to “X& x”. Since you’re gaining nothing by adding the const after the &, you shouldn’t add it: it will confuse people — the const will make some people think that the X is const, as if you had said “const X& x”.

i think you should use hidden better.

activityIndicator.hidden = YES

Guys don't forget to call xmlWriter.Close() and xmlWriter.Dispose() or else your string won't finish creating. It will just be an empty string

JSONArray has a constructor which takes a String source (presumed to be an array).

So something like this

JSONArray array = new JSONArray(yourJSONArrayAsString);

Python 2.7

In python 2, the keys(), values(), and items() functions of OrderedDict return lists. Using values as an example, the simplest way is

d.values()[0]  # "python"
d.values()[1]  # "spam"

For large collections where you only care about a single index, you can avoid creating the full list using the generator versions, iterkeys, itervalues and iteritems:

import itertools
next(itertools.islice(d.itervalues(), 0, 1))  # "python"
next(itertools.islice(d.itervalues(), 1, 2))  # "spam"

The indexed.py package provides IndexedOrderedDict, which is designed for this use case and will be the fastest option.

from indexed import IndexedOrderedDict
d = IndexedOrderedDict({'foo':'python','bar':'spam'})
d.values()[0]  # "python"
d.values()[1]  # "spam"

Using itervalues can be considerably faster for large dictionaries with random access:

$ python2 -m timeit -s 'from collections import OrderedDict; from random import randint; size = 1000;   d = OrderedDict({i:i for i in range(size)})'  'i = randint(0, size-1); d.values()[i:i+1]'

$ python2 -m timeit -s 'from collections import OrderedDict; from random import randint; size = 10000;  d = OrderedDict({i:i for i in range(size)})' 'i = randint(0, size-1); d.values()[i:i+1]'

$ python2 -m timeit -s 'from collections import OrderedDict; from random import randint; size = 1000;   d = OrderedDict({i:i for i in range(size)})' 'i = randint(0, size-1); next(itertools.islice(d.itervalues(), i, i+1))'

Python 3.6

Python 3 has the same two basic options (list vs generator), but the dict methods return generators by default.

List method:

list(d.values())[0]  # "python"
list(d.values())[1]  # "spam"

Generator method:

import itertools
next(itertools.islice(d.values(), 0, 1))  # "python"
next(itertools.islice(d.values(), 1, 2))  # "spam"

Python 3 dictionaries are an order of magnitude faster than python 2 and have similar speedups for using generators.

The documentation here encourages listening to the onbeforeunload event and/or adding an event listener on window.

window.addEventListener('beforeunload', function(event) {
  //do something here
}, false);

You can also just populate the .onunload or .onbeforeunload properties of window with a function or a function reference.

Though behaviour is not standardized across browsers, the function may return a value that the browser will display when confirming whether to leave the page.

NoClassDefFoundError in Java:

Definition:

NoClassDefFoundError will come if a class was present during compile time but not available in java classpath during runtime. Normally you will see below line in log when you get NoClassDefFoundError: Exception in thread "main" java.lang.NoClassDefFoundError

Possible Causes:

1. The class is not available in Java Classpath.

2. You might be running your program using jar command and class was not defined in manifest file's ClassPath attribute.

3. Any start-up script is overriding Classpath environment variable.

4. Because NoClassDefFoundError is a subclass of java.lang.LinkageError it can also come if one of it dependency like native library may not available.

5. Check for java.lang.ExceptionInInitializerError in your log file. NoClassDefFoundError due to the failure of static initialization is quite common.

6. If you are working in J2EE environment than the visibility of Class among multiple Classloader can also cause java.lang.NoClassDefFoundError, see examples and scenario section for detailed discussion.

Possible Resolutions:

1. Verify that all required Java classes are included in the application’s classpath. The most common mistake is not to include all the necessary classes, before starting to execute a Java application that has dependencies on some external libraries.

2. The classpath of the application is correct, but the Classpath environment variable is overridden before the application’s execution.

3. Verify that the aforementioned ExceptionInInitializerError does not appear in the stack trace of your application.

You've seen the formal definitions above, for all they are worth.

But don't get too hung up on definitions. Let's just look more at the sense of things here.

JavaBeans are used in Enterprise Java applications, where users frequently access data and/or application code remotely, i.e. from a server (via web or private network) via a network. The data involved must therefore be streamed in serial format into or out of the users' computers - hence the need for Java EE objects to implement the interface Serializable. This much of a JavaBean's nature is no different to Java SE application objects whose data is read in from, or written out to, a file system. Using Java classes reliably over a network from a range of user machine/OS combinations also demands the adoption of conventions for their handling. Hence the requirement for implementing these classes as public, with private attributes, a no-argument constructor and standardised getters and setters.

Java EE applications will also use classes other than those that were implemented as JavaBeans. These could be used in processing input data or organizing output data but will not be used for objects transferred over a network. Hence the above considerations need not be applied to them bar that the be valid as Java objects. These latter classes are referred to as POJOs - Plain Old Java Objects.

All in all, you could see Java Beans as just Java objects adapted for use over a network.

There's an awful lot of hype - and no small amount of humbug - in the software world since 1995.

git format-patch also has the -B flag.

The description in the man page leaves much to be desired, but in simple language it's the threshold format-patch will abide to before doing a total re-write of the file (by a single deletion of everything old, followed by a single insertion of everything new).

This proved very useful for me when manual editing was too cumbersome, and the source was more authoritative than my destination.

An example:

git format-patch -B10% --stdout my_tag_name > big_patch.patch
git am -3 -i < big_patch.patch

You can use the Distinct method to return an IEnumerable<T> of distinct items:

var uniqueItems = yourList.Distinct();

And if you need the sequence of unique items returned as a List<T>, you can add a call to ToList:

var uniqueItemsList = yourList.Distinct().ToList();

Simply this should do:

php test.php

tl;dr

Use either of the Map implementations bundled with Java 6 and later that implement NavigableMap (the successor to SortedMap):

• Use TreeMap if running single-threaded, or if the map is to be read-only across threads after first being populated.
• Use ConcurrentSkipListMap if manipulating the map across threads.

NavigableMap

FYI, the SortedMap interface was succeeded by the NavigableMap interface.

You would only need to use SortedMap if using 3rd-party implementations that have not yet declared their support of NavigableMap. Of the maps bundled with Java, both of the implementations that implement SortedMap also implement NavigableMap.

Interface versus concrete class

s SortedMap the best answer? TreeMap?

As others mentioned, SortedMap is an interface while TreeMap is one of multiple implementations of that interface (and of the more recent NavigableMap.

Having an interface allows you to write code that uses the map without breaking if you later decide to switch between implementations.

NavigableMap< Employee , Project > currentAssignments = new TreeSet<>() ;
currentAssignments.put( alice , writeAdCopyProject ) ; 
currentAssignments.put( bob , setUpNewVendorsProject ) ; 

This code still works if later change implementations. Perhaps you later need a map that supports concurrency for use across threads. Change that declaration to:

NavigableMap< Employee , Project > currentAssignments = new ConcurrentSkipListMap<>() ;

…and the rest of your code using that map continues to work.

Choosing implementation

There are ten implementations of Map bundled with Java 11. And more implementations provided by 3rd parties such as Google Guava.

Here is a graphic table I made highlighting the various features of each. Notice that two of the bundled implementations keep the keys in sorted order by examining the key’s content. Also, EnumMap keeps its keys in the order of the objects defined on that enum. Lastly, the LinkedHashMap remembers original insertion order.

What is a DLL?

DLL files are binary files that can contain executable code and resources like images, etc. Unlike applications, these cannot be directly executed, but an application will load them as and when they are required (or all at once during startup).

Are they important?

Most applications will load the DLL files they require at startup. If any of these are not found the system will not be able to start the process at all.

DLL files might require other DLL files

In the same way that an application requires a DLL file, a DLL file might be dependent on other DLL files itself. If one of these DLL files in the chain of dependency is not found, the application will not load. This is debugged easily using any dependency walker tools, like Dependency Walker.

There are so many of them in the system folders

Most of the system functionality is exposed to a user program in the form of DLL files as they are a standard form of sharing code / resources. Each functionality is kept separately in different DLL files so that only the required DLL files will be loaded and thus reduce the memory constraints on the system.

Installed applications also use DLL files

DLL files also becomes a form of separating functionalities physically as explained above. Good applications also try to not load the DLL files until they are absolutely required, which reduces the memory requirements. This too causes applications to ship with a lot of DLL files.

DLL Hell

However, at times system upgrades often breaks other programs when there is a version mismatch between the shared DLL files and the program that requires them. System checkpoints and DLL cache, etc. have been the initiatives from M$ to solve this problem. The .NET platform might not face this issue at all.

How do we know what's inside a DLL file?

You have to use an external tool like DUMPBIN or Dependency Walker which will not only show what publicly visible functions (known as exports) are contained inside the DLL files and also what other DLL files it requires and which exports from those DLL files this DLL file is dependent upon.

How do we create / use them?

Refer the programming documentation from your vendor. For C++, refer to LoadLibrary in MSDN.

As other have stated, use an interpreted expression with curly braces.

But do not forget to set a default.
Others has suggested using a OR statement to set a empty string if undefined.

But it would be even better to declare your Props.

Full example:

import React, { Component } from 'react';
import PropTypes from 'prop-types';

class Pill extends Component {

  render() {

    return (
      <button className={`pill ${ this.props.className }`}>{this.props.children}</button>
    );
  }

}

Pill.propTypes = {
  className: PropTypes.string,
};

Pill.defaultProps = {
  className: '',
};

Like the other answers you can do theTypeIs = Object.keys(myVar)[0]; to get the first key. If you are expecting more keys, you can use

Object.keys(myVar).forEach(function(k) {
    if(k === "typeA") {
        // do stuff
    }
    else if (k === "typeB") {
        // do more stuff
    }
    else {
        // do something
    }
});

The easiest way to do it is to add mb-5 to your classes. That is <div class='row mb-5'>.

NOTE:

• mb varies betweeen 1 to 5
• The Div MUST have the row class

When I got this error, it may have been because of my UPDATE syntax being wrong, but after I fixed the update query I got the same error again...so I went to the ODBC Data Source Administrator and found that my connection was read-only. After I made the connection read-write and re-connected it worked just fine.

All I had to do was to run this command:

git config --global credential.helper wincred

Then I was prompted for password twice.

Next time it worked without prompting me for password.

Both

SuperClass.__init__(self, x)

or

super(SubClass,self).__init__( x )

will work (I prefer the 2nd one, as it adheres more to the DRY principle).

See here: http://docs.python.org/reference/datamodel.html#basic-customization

Please check https://www.sqlite.org/lang_altertable.html#otheralter

The only schema altering commands directly supported by SQLite are the "rename table" and "add column" commands shown above. However, applications can make other arbitrary changes to the format of a table using a simple sequence of operations. The steps to make arbitrary changes to the schema design of some table X are as follows:

1. If foreign key constraints are enabled, disable them using PRAGMA foreign_keys=OFF.
2. Start a transaction.
3. Remember the format of all indexes and triggers associated with table X. This information will be needed in step 8 below. One way to do this is to run a query like the following: SELECT type, sql FROM sqlite_master WHERE tbl_name='X'.
4. Use CREATE TABLE to construct a new table "new_X" that is in the desired revised format of table X. Make sure that the name "new_X" does not collide with any existing table name, of course.
5. Transfer content from X into new_X using a statement like: INSERT INTO new_X SELECT ... FROM X.
6. Drop the old table X: DROP TABLE X.
7. Change the name of new_X to X using: ALTER TABLE new_X RENAME TO X.
8. Use CREATE INDEX and CREATE TRIGGER to reconstruct indexes and triggers associated with table X. Perhaps use the old format of the triggers and indexes saved from step 3 above as a guide, making changes as appropriate for the alteration.
9. If any views refer to table X in a way that is affected by the schema change, then drop those views using DROP VIEW and recreate them with whatever changes are necessary to accommodate the schema change using CREATE VIEW.
10. If foreign key constraints were originally enabled then run PRAGMA foreign_key_check to verify that the schema change did not break any foreign key constraints.
11. Commit the transaction started in step 2.
12. If foreign keys constraints were originally enabled, reenable them now.

The procedure above is completely general and will work even if the schema change causes the information stored in the table to change. So the full procedure above is appropriate for dropping a column, changing the order of columns, adding or removing a UNIQUE constraint or PRIMARY KEY, adding CHECK or FOREIGN KEY or NOT NULL constraints, or changing the datatype for a column, for example.

if the value is 0 then it wasn't successful, but if 1 then successful.

$this->db->affected_rows();

Assuming this is actual production code you'll be writing, then I suggest using the solution to this sort of thing that's already been solved - Apache Commons IO, specifically FileUtils.listFiles(). It handles nested directories, filters (based on name, modification time, etc).

For example, for your regex:

Collection files = FileUtils.listFiles(
  dir, 
  new RegexFileFilter("^(.*?)"), 
  DirectoryFileFilter.DIRECTORY
);

This will recursively search for files matching the ^(.*?) regex, returning the results as a collection.

It's worth noting that this will be no faster than rolling your own code, it's doing the same thing - trawling a filesystem in Java is just slow. The difference is, the Apache Commons version will have no bugs in it.

You can use .is(':visible')

Selects all elements that are visible.

For example:

if($('#selectDiv').is(':visible')){

Also, you can get the div which is visible by:

$('div:visible').callYourFunction();

Live example:

console.log($('#selectDiv').is(':visible'));_x000D_
console.log($('#visibleDiv').is(':visible'));

#selectDiv {_x000D_
  display: none;  _x000D_
}

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

check your Bundle identifier for your project and you give Bundle identifier for your app which create on developer.facebook.com that they are same or not.

It also happens when I just want to compile opencv2.3.2 with mingw32 (in tdm-gcc suites). Often when I install the tdm-gcc, I would like to rename the mingw32-make.exe to make.exe. And I thinks this could be the question. If cmake is asked to generated a MinGW Makefiles, It would try to find ming32-make.exe instead of make.exe. So I copy the make.exe to mingw32-make.exe and reconfigure in Cmake-gui. Finally it works! So I'd like to advise to find whether you have mingw32-make.exe or not to solve this question.

Do you really want to style the <div>? Or do you want to style the <input type="button">? You should use the correct selector if you want the latter:

input[type=button] {
    color:#08233e;
    font:2.4em Futura, ‘Century Gothic’, AppleGothic, sans-serif;
    font-size:70%;
    /* ... other rules ... */
    cursor:pointer;
}

input[type=button]:hover {
    background-color:rgba(255,204,0,0.8);
}

I also had a similar exception when debugging in Eclipse. When I moused-over an object, the pop up box displayed an com.sun.jdi.InvocationException message. The root cause for me was not the toString() method of my class, but rather the hashCode() method. It was causing a NullPointerException, which caused the com.sun.jdi.InvocationException to appear during debugging. Once I took care of the null pointer, everything worked as expected.

My psychic debugging skills tell me that your submit button is named submit.
Therefore, form.submit refers to the button rather than the method.

Rename the button to something else so that form.submit refers to the method again.

Yes, you can put arrays in sessions, example:

$_SESSION['name_here'] = $your_array;

Now you can use the $_SESSION['name_here'] on any page you want but make sure that you put the session_start() line before using any session functions, so you code should look something like this:

 session_start();
 $_SESSION['name_here'] = $your_array;

Possible Example:

 session_start();
 $_SESSION['name_here'] = $_POST;

Now you can get field values on any page like this:

 echo $_SESSION['name_here']['field_name'];

As for the second part of your question, the session variables remain there unless you assign different array data:

 $_SESSION['name_here'] = $your_array;

Session life time is set into php.ini file.

JavaScript doesn't have a built-in init() function, that is, it's not a part of the language. But it's not uncommon (in a lot of languages) for individual programmers to create their own init() function for initialisation stuff.

A particular init() function may be used to initialise the whole webpage, in which case it would probably be called from document.ready or onload processing, or it may be to initialise a particular type of object, or...well, you name it.

What any given init() does specifically is really up to whatever the person who wrote it needed it to do. Some types of code don't need any initialisation.

function init() {
  // initialisation stuff here
}

// elsewhere in code
init();

For the parameter or without parameter URLs Use this :

Method 1:

 $currentURL = current_url(); //for simple URL
 $params = $_SERVER['QUERY_STRING']; //for parameters
 $fullURL = $currentURL . '?' . $params; //full URL with parameter

Method 2:

$full_url = (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] === 'on' ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

Method 3:

base_url(uri_string());

Webkit is the html/css rendering engine used in Apple's Safari browser, and in Google's Chrome. css values prefixes with -webkit- are webkit-specific, they're usually CSS3 or other non-standardised features.

to answer update 2 w3c is the body that tries to standardize these things, they write the rules, then programmers write their rendering engine to interpret those rules. So basically w3c says DIVs should work "This way" the engine-writer then uses that rule to write their code, any bugs or mis-interpretations of the rules cause the compatibility issues.

This happens in the following scenario: When working on Windows, the IDE is more than likely configured to edit files in Cp1252, which is a Microsoft adaptation of latin-11. The developer checks in, and the Continuous Integration server (usually running on Linux, which nowadays is all utf8) picks up the file, and tries to compile as a UTF-8 file, hence the warning.

Try changing the encoding to cp1252. This works. To avoid future problems of this kind, use the same encoding on all the developer machines.

Good luck...

Set the button image like this:

let myImage = UIImage(named: "myImageName")
myButton.setImage(myImage , forState: UIControlState.Normal)

where myImageName is the name of your image in your asset catalog.

Try this solution:

Go to->

1. xammp ->htdocs-> then open index.php from the htdocs folder
2. you can modify the dashboard
3. restart the server

Example Code index.php :

    <?php
    if (!empty($_SERVER['HTTPS']) && ('on' == $_SERVER['HTTPS'])) {
        $uri = 'https://';
    } else {
        $uri = 'http://';
    }
    $uri .= $_SERVER['HTTP_HOST'];
    header('Location: '.$uri.'/dashboard/');
    exit;
   ?>

To click Ctrl+A, you can do it with Actions

  Actions action = new Actions(); 
  action.keyDown(Keys.CONTROL).sendKeys(String.valueOf('\u0061')).perform();

\u0061 represents the character 'a'

\u0041 represents the character 'A'

To press other characters refer the unicode character table - http://unicode.org/charts/PDF/U0000.pdf

At least in Visual C++: printf (and other ACSII functions): %s represents an ASCII string %S is a Unicode string wprintf (and other Unicode functions): %s is a Unicode string %S is an ASCII string

As far as no compiler warnings, printf uses a variable argument list, with only the first argument able to be type checked. The compiler is not designed to parse the format string and type check the parameters that match. In cases of functions like printf, that is up to the programmer

Did you want the HTML or text that is inside the li tag?

If so, use either:

$(this).html()

or:

$(this).text()

The val() is for form fields only.

For my interactive day-to-day gitting (where I diff the working tree against the HEAD all the time, and would like to have untracked files included in the diff), add -N/--intent-to-add is unusable, because it breaks git stash.

So here's my git diff replacement. It's not a particularly clean solution, but since I really only use it interactively, I'm OK with a hack:

d() {
    if test "$#" = 0; then
        (
            git diff --color
            git ls-files --others --exclude-standard |
                while read -r i; do git diff --color -- /dev/null "$i"; done
        ) | `git config --get core.pager`
    else
        git diff "$@"
    fi
}

Typing just d will include untracked files in the diff (which is what I care about in my workflow), and d args... will behave like regular git diff.

Notes:

• We're using the fact here that git diff is really just individual diffs concatenated, so it's not possible to tell the d output from a "real diff" -- except for the fact that all untracked files get sorted last.
• The only problem with this function is that the output is colorized even when redirected; but I can't be bothered to add logic for that.
• I couldn't find any way to get untracked files included by just assembling a slick argument list for git diff. If someone figures out how to do this, or if maybe a feature gets added to git at some point in the future, please leave a note here!

I had some dealings with the select \ multi-select this is what did the trick for me

<select name="mySelect" multiple="multiple">
    <option>Foo</option>
    <option>Bar</option>
    <option>Foo Bar</option>
    <option>Bar Foo</option>
</select>

why you not use curl? logically, if you execute php file, you will execute that by url on your browser. its very simple if you run curl

while(true)
{
    sleep(60); // sleep for 60 sec = 1 minute

    $s = curl_init();
    curl_setopt($s,CURLOPT_URL, $your_php_url_to_cron); 
    curl_exec($s); 
    curl_getinfo($s,CURLINFO_HTTP_CODE); 
    curl_close($s);
}

It can be accomplished like this docs

$('input').trigger("keydown", {which: 50});

Spring Framework org.springframework.util.SerializationUtils

byte[] data = SerializationUtils.serialize(obj);

Similar situation. It was working. Then, I started to include pytables. At first view, no reason to errors. I decided to use another function, that has a domain constraint (elipse) and received the following error:

TypeError: 'numpy.float64' object cannot be interpreted as an integer

or

TypeError: 'numpy.float64' object is not iterable

The crazy thing: the previous function I was using, no code changed, started to return the same error. My intermediary function, already used was:

def MinMax(x, mini=0, maxi=1)
    return max(min(x,mini), maxi)

The solution was avoid numpy or math:

def MinMax(x, mini=0, maxi=1)
    x = [x_aux if x_aux > mini else mini for x_aux in x]
    x = [x_aux if x_aux < maxi else maxi for x_aux in x]
    return max(min(x,mini), maxi)

Then, everything calm again. It was like one library possessed max and min!

Example of AngularJS "global variables" using $rootScope:

Controller 1 sets the global variable:

function MyCtrl1($scope, $rootScope) {
    $rootScope.name = 'anonymous'; 
}

Controller 2 reads the global variable:

function MyCtrl2($scope, $rootScope) {
    $scope.name2 = $rootScope.name; 
}

Here is a working jsFiddle: http://jsfiddle.net/natefriedman/3XT3F/1/

I'd recommend to use an array for storing all values via __set().

class foo {

    protected $values = array();

    public function __get( $key )
    {
        return $this->values[ $key ];
    }

    public function __set( $key, $value )
    {
        $this->values[ $key ] = $value;
    }

}

This way you make sure, that you can't access the variables in another way (note that $values is protected), to avoid collisions.

I got the resources on C# (Desktop WPF W/ .NET Framework 4.8) using the code below

{DefaultNamespace}.Properties.Resources.{ResourceName}

Here's a simple example. I didn't get fancy with the html or the servlet, but you should get the idea.

I hope this helps you out.

<html>
<body>
<form method="post" action="/myServlet">
<input type="text" name="username" />
<input type="password" name="password" />
<input type="submit" />
</form>
</body>
</html>

Now for the Servlet

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;

public class MyServlet extends HttpServlet {
  public void doPost(HttpServletRequest request,
                    HttpServletResponse response)
      throws ServletException, IOException {

    String userName = request.getParameter("username");
    String password = request.getParameter("password");
    ....
    ....
  }
}

You could also use ld option -Bdynamic

gcc <objectfiles> -static -lstatic1 -lstatic2 -Wl,-Bdynamic -ldynamic1 -ldynamic2

All libraries after it (including system ones linked by gcc automatically) will be linked dynamically.

It's worth noting that if you want to sort particular properties descending, you don't want to simply append .reverse() at the end, as this will make all of the sorts descending.

To make particular sorts descending, chain your sorts from least significant to most significant, calling .reverse() after each sort that you want to be descending.

var data = _(data).chain()
    .sort("date")
    .reverse()    // sort by date descending
    .sort("name") // sort by name ascending
    .result()

Since _'s sort is a stable sort, you can safely chain and reverse sorts because if two items have the same value for a property, their order is preserved.

Double brace initialization is an option:

List<String> symbolsPresent = new ArrayList<String>() {{
   add("ONE");
   add("TWO");
   add("THREE");
   add("FOUR");
}};

Note that the String generic type argument is necessary in the assigned expression as indicated by JLS §15.9

It is a compile-time error if a class instance creation expression declares an anonymous class using the "<>" form for the class's type arguments.

Is this possible using HttpWebRequest and HttpWebResponse?

You could have your web server simply catch and write the exception text into the body of the response, then set status code to 500. Now the client would throw an exception when it encounters a 500 error but you could read the response stream and fetch the message of the exception.

So you could catch a WebException which is what will be thrown if a non 200 status code is returned from the server and read its body:

catch (WebException ex)
{
    using (var stream = ex.Response.GetResponseStream())
    using (var reader = new StreamReader(stream))
    {
        Console.WriteLine(reader.ReadToEnd());
    }
}
catch (Exception ex)
{
    // Something more serious happened
    // like for example you don't have network access
    // we cannot talk about a server exception here as
    // the server probably was never reached
}

this how you reset the enitityManager in Symfony3. It should reopen the em if it has been closed:

In a Controller:

$em = $this->getDoctrine()->resetEntityManager();

In a service:

  if (!$this->em->isOpen()) {
        $this->managerRegistry->resetManager('managername');
        $this->em = $this->managerRegistry->getManager('default');
    }

    $this->em->persist(...);

Don't forget to inject the '@doctrine' as a service argument in service.yml!

I'm wondering, if this problem happens if different methodes concurrently tries to access the same entity at the same time?

               <MenuItem Header="File2"/>
               <MenuItem Header="File3"/>
            </MenuItem>
            <MenuItem Header="Open"/>

Simple code for replace all spaces

Yes, this is a 'new style' object. It was a feature introduced in python2.2.

New style objects have a different object model to classic objects, and some things won't work properly with old style objects, for instance, super(), @property and descriptors. See this article for a good description of what a new style class is.

SO link for a description of the differences: What is the difference between old style and new style classes in Python?

couple of months back, I had the same requirement for one of my projects. I searched a bit for it and found out the following solution. This is not the only solution but I found it to one of the simpler one.

Use the webservice at http://www.webservicex.net/uszip.asmx.
Specifically GetInfoByZIP() method.

You will be able to query by any zipcode (ex: 40220) and you will have a response back as the following...

<?xml version="1.0" encoding="UTF-8"?>
 <NewDataSet>
  <Table>
   <CITY>Louisville</CITY> 
   <STATE>KY</STATE> 
   <ZIP>40220</ZIP> 
   <AREA_CODE>502</AREA_CODE> 
   <TIME_ZONE>E</TIME_ZONE> 
  </Table> 
</NewDataSet>

Hope this helps...

This worked me for UNICODE (UTF8) sentences too:

function myUTF8truncate($string, $width){
    if (mb_str_word_count($string) > $width) {
        $string= preg_replace('/((\w+\W*|| [\p{L}]+\W*){'.($width-1).'}(\w+))(.*)/', '${1}', $string);
    }
    return $string;
}

You need to call $compile on the HTML string before inserting it into the DOM so that angular gets a chance to perform the binding.

In your fiddle, it would look something like this.

$("#dynamicContent").html(
  $compile(
    "<button ng-click='count = count + 1' ng-init='count=0'>Increment</button><span>count: {{count}} </span>"
  )(scope)
);

Obviously, $compile must be injected into your controller for this to work.

Read more in the $compile documentation.

The correct API to use is UIView systemLayoutSizeFittingSize:, passing either UILayoutFittingCompressedSize or UILayoutFittingExpandedSize.

For a normal UIView using autolayout this should just work as long as your constraints are correct. If you want to use it on a UITableViewCell (to determine row height for example) then you should call it against your cell contentView and grab the height.

Further considerations exist if you have one or more UILabel's in your view that are multiline. For these it is imperitive that the preferredMaxLayoutWidth property be set correctly such that the label provides a correct intrinsicContentSize, which will be used in systemLayoutSizeFittingSize's calculation.

EDIT: by request, adding example of height calculation for a table view cell

Using autolayout for table-cell height calculation isn't super efficient but it sure is convenient, especially if you have a cell that has a complex layout.

As I said above, if you're using a multiline UILabel it's imperative to sync the preferredMaxLayoutWidth to the label width. I use a custom UILabel subclass to do this:

@implementation TSLabel

- (void) layoutSubviews
{
    [super layoutSubviews];

    if ( self.numberOfLines == 0 )
    {
        if ( self.preferredMaxLayoutWidth != self.frame.size.width )
        {
            self.preferredMaxLayoutWidth = self.frame.size.width;
            [self setNeedsUpdateConstraints];
        }
    }
}

- (CGSize) intrinsicContentSize
{
    CGSize s = [super intrinsicContentSize];

    if ( self.numberOfLines == 0 )
    {
        // found out that sometimes intrinsicContentSize is 1pt too short!
        s.height += 1;
    }

    return s;
}

@end

Here's a contrived UITableViewController subclass demonstrating heightForRowAtIndexPath:

#import "TSTableViewController.h"
#import "TSTableViewCell.h"

@implementation TSTableViewController

- (NSString*) cellText
{
    return @"Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.";
}

#pragma mark - Table view data source

- (NSInteger) numberOfSectionsInTableView: (UITableView *) tableView
{
    return 1;
}

- (NSInteger) tableView: (UITableView *)tableView numberOfRowsInSection: (NSInteger) section
{
    return 1;
}

- (CGFloat) tableView: (UITableView *) tableView heightForRowAtIndexPath: (NSIndexPath *) indexPath
{
    static TSTableViewCell *sizingCell;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{

        sizingCell = (TSTableViewCell*)[tableView dequeueReusableCellWithIdentifier: @"TSTableViewCell"];
    });

    // configure the cell
    sizingCell.text = self.cellText;

    // force layout
    [sizingCell setNeedsLayout];
    [sizingCell layoutIfNeeded];

    // get the fitting size
    CGSize s = [sizingCell.contentView systemLayoutSizeFittingSize: UILayoutFittingCompressedSize];
    NSLog( @"fittingSize: %@", NSStringFromCGSize( s ));

    return s.height;
}

- (UITableViewCell *) tableView: (UITableView *) tableView cellForRowAtIndexPath: (NSIndexPath *) indexPath
{
    TSTableViewCell *cell = (TSTableViewCell*)[tableView dequeueReusableCellWithIdentifier: @"TSTableViewCell" ];

    cell.text = self.cellText;

    return cell;
}

@end

A simple custom cell:

#import "TSTableViewCell.h"
#import "TSLabel.h"

@implementation TSTableViewCell
{
    IBOutlet TSLabel* _label;
}

- (void) setText: (NSString *) text
{
    _label.text = text;
}

@end

And, here's a picture of the constraints defined in the Storyboard. Note that there are no height/width constraints on the label - those are inferred from the label's intrinsicContentSize:

Take a look at the JVM args: http://java.sun.com/javase/technologies/hotspot/vmoptions.jsp#DebuggingOptions

You can subclass HandleErrorAttribute and override its OnException member (no need to copy) so that it logs the exception with ELMAH and only if the base implementation handles it. The minimal amount of code you need is as follows:

using System.Web.Mvc;
using Elmah;

public class HandleErrorAttribute : System.Web.Mvc.HandleErrorAttribute
{
    public override void OnException(ExceptionContext context)
    {
        base.OnException(context);
        if (!context.ExceptionHandled) 
            return;
        var httpContext = context.HttpContext.ApplicationInstance.Context;
        var signal = ErrorSignal.FromContext(httpContext);
        signal.Raise(context.Exception, httpContext);
    }
}

The base implementation is invoked first, giving it a chance to mark the exception as being handled. Only then is the exception signaled. The above code is simple and may cause issues if used in an environment where the HttpContext may not be available, such as testing. As a result, you will want code that is that is more defensive (at the cost of being slightly longer):

using System.Web;
using System.Web.Mvc;
using Elmah;

public class HandleErrorAttribute : System.Web.Mvc.HandleErrorAttribute
{
    public override void OnException(ExceptionContext context)
    {
        base.OnException(context);
        if (!context.ExceptionHandled       // if unhandled, will be logged anyhow
            || TryRaiseErrorSignal(context) // prefer signaling, if possible
            || IsFiltered(context))         // filtered?
            return;

        LogException(context);
    }

    private static bool TryRaiseErrorSignal(ExceptionContext context)
    {
        var httpContext = GetHttpContextImpl(context.HttpContext);
        if (httpContext == null)
            return false;
        var signal = ErrorSignal.FromContext(httpContext);
        if (signal == null)
            return false;
        signal.Raise(context.Exception, httpContext);
        return true;
    }

    private static bool IsFiltered(ExceptionContext context)
    {
        var config = context.HttpContext.GetSection("elmah/errorFilter")
                        as ErrorFilterConfiguration;

        if (config == null)
            return false;

        var testContext = new ErrorFilterModule.AssertionHelperContext(
                              context.Exception, 
                              GetHttpContextImpl(context.HttpContext));
        return config.Assertion.Test(testContext);
    }

    private static void LogException(ExceptionContext context)
    {
        var httpContext = GetHttpContextImpl(context.HttpContext);
        var error = new Error(context.Exception, httpContext);
        ErrorLog.GetDefault(httpContext).Log(error);
    }

    private static HttpContext GetHttpContextImpl(HttpContextBase context)
    {
        return context.ApplicationInstance.Context;
    }
}

This second version will try to use error signaling from ELMAH first, which involves the fully configured pipeline like logging, mailing, filtering and what have you. Failing that, it attempts to see whether the error should be filtered. If not, the error is simply logged. This implementation does not handle mail notifications. If the exception can be signaled then a mail will be sent if configured to do so.

You may also have to take care that if multiple HandleErrorAttribute instances are in effect then duplicate logging does not occur, but the above two examples should get your started.

I'm going to leave this one here: https://stackoverflow.com/a/14509697/1356953

Please note that this works with java.lang.SuppressWarningsso no need to use a separate annotation.

@SuppressWarnings on a field only suppresses findbugs warnings reported for that field declaration, not every warning associated with that field.

For example, this suppresses the "Field only ever set to null" warning:

@SuppressWarnings("UWF_NULL_FIELD") String s = null; I think the best you can do is isolate the code with the warning into the smallest method you can, then suppress the warning on the whole method.

Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.

You can check this by running in Windows PowerShell:

> Get-Service ssh-agent

And then check the output of status is not running.

Status   Name               DisplayName
------   ----               -----------
Stopped  ssh-agent          OpenSSH Authentication Agent

Then check that the service has been disabled by running

> Get-Service ssh-agent | Select StartType

StartType
---------
Disabled

I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:

 > Get-Service -Name ssh-agent | Set-Service -StartupType Manual

Alternatively, you can set it through the GUI if you prefer.

The 'pidof' command will not display pids of shell/perl/python scripts. So to find the process id’s of my Perl script I had to use the -x option i.e. 'pidof -x perlscriptname'

Here is the code for it, enjoy!, I picked that up from the dotNetReference type the "using" statement inside the namespace line 106 http://referencesource.microsoft.com/#mscorlib/microsoft/win32/win32native.cs

using System;
using System.Collections.Generic;
namespace UsingStatement

    using Typedeffed = System.Int32;
    using TypeDeffed2 = List<string>;
    class Program
    {
        static void Main(string[] args)
        {
        Typedeffed numericVal = 5;
        Console.WriteLine(numericVal++);

        TypeDeffed2 things = new TypeDeffed2 { "whatever"};
        }
    }
}

Please try this.

// Find out what the map's zoom level is
zoom = map.getZoom();
if (zoom == 1) {
  // If the zoom level is that low, means it's looking around the
world.
  // Swap the sw and ne coords
  viewportBounds = new
google.maps.LatLngBounds(results[0].geometry.location, initialLatLng);
  map.fitBounds(viewportBounds);
}

If this will helpful to you.

All the best

It formats the string as two uppercase hexadecimal characters.

In more depth, the argument "X2" is a "format string" that tells the ToString() method how it should format the string. In this case, "X2" indicates the string should be formatted in Hexadecimal.

byte.ToString() without any arguments returns the number in its natural decimal representation, with no padding.

Microsoft documents the standard numeric format strings which generally work with all primitive numeric types' ToString() methods. This same pattern is used for other types as well: for example, standard date/time format strings can be used with DateTime.ToString().

I followed the thread and tired all things but didn't work. Finally I saw that my eclipse shortcut target is like below

I simply removed -data option and it worked. Now I got popup to choose workspace at startup.
