I you are using Visual Studio 2012, download and install Update 2 that Microsoft released recently (as of 4/2013).

Visual Studio 2012 Update 2

There are some bug fixes in that update related to the issue.

Yes you can. Just check my fiddle for clarification. For demo purpose i kept the code in fiddle at same location. You can extract that code as shown in two different Javascript files and load them in html file.

https://jsfiddle.net/mvora/mrLmkxmo/

 /******** PUT THIS CODE IN ONE JS FILE *******/

    var secondFileFuntion = function(){
        this.name = 'XYZ';
    }

    secondFileFuntion.prototype.getSurname = function(){
     return 'ABC';
    }


    var secondFileObject = new secondFileFuntion();

    /******** Till Here *******/

    /******** PUT THIS CODE IN SECOND JS FILE *******/

    function firstFileFunction(){
      var name = secondFileObject.name;
      var surname = secondFileObject.getSurname()
      alert(name);
      alert(surname );
    }

    firstFileFunction();

If you make an object using the constructor function and trying access the property or method from it in second file, it will give you the access of properties which are present in another file.

Just take care of sequence of including these files in index.html

There's no perfect solution for detecting whether JS code is executed on a mobile browser, but the following two options should work in most cases.

Option 1 : browser sniffing

!function(a){var b=/iPhone/i,c=/iPod/i,d=/iPad/i,e=/(?=.*\bAndroid\b)(?=.*\bMobile\b)/i,f=/Android/i,g=/(?=.*\bAndroid\b)(?=.*\bSD4930UR\b)/i,h=/(?=.*\bAndroid\b)(?=.*\b(?:KFOT|KFTT|KFJWI|KFJWA|KFSOWI|KFTHWI|KFTHWA|KFAPWI|KFAPWA|KFARWI|KFASWI|KFSAWI|KFSAWA)\b)/i,i=/IEMobile/i,j=/(?=.*\bWindows\b)(?=.*\bARM\b)/i,k=/BlackBerry/i,l=/BB10/i,m=/Opera Mini/i,n=/(CriOS|Chrome)(?=.*\bMobile\b)/i,o=/(?=.*\bFirefox\b)(?=.*\bMobile\b)/i,p=new RegExp("(?:Nexus 7|BNTV250|Kindle Fire|Silk|GT-P1000)","i"),q=function(a,b){return a.test(b)},r=function(a){var r=a||navigator.userAgent,s=r.split("[FBAN");return"undefined"!=typeof s[1]&&(r=s[0]),s=r.split("Twitter"),"undefined"!=typeof s[1]&&(r=s[0]),this.apple={phone:q(b,r),ipod:q(c,r),tablet:!q(b,r)&&q(d,r),device:q(b,r)||q(c,r)||q(d,r)},this.amazon={phone:q(g,r),tablet:!q(g,r)&&q(h,r),device:q(g,r)||q(h,r)},this.android={phone:q(g,r)||q(e,r),tablet:!q(g,r)&&!q(e,r)&&(q(h,r)||q(f,r)),device:q(g,r)||q(h,r)||q(e,r)||q(f,r)},this.windows={phone:q(i,r),tablet:q(j,r),device:q(i,r)||q(j,r)},this.other={blackberry:q(k,r),blackberry10:q(l,r),opera:q(m,r),firefox:q(o,r),chrome:q(n,r),device:q(k,r)||q(l,r)||q(m,r)||q(o,r)||q(n,r)},this.seven_inch=q(p,r),this.any=this.apple.device||this.android.device||this.windows.device||this.other.device||this.seven_inch,this.phone=this.apple.phone||this.android.phone||this.windows.phone,this.tablet=this.apple.tablet||this.android.tablet||this.windows.tablet,"undefined"==typeof window?this:void 0},s=function(){var a=new r;return a.Class=r,a};"undefined"!=typeof module&&module.exports&&"undefined"==typeof window?module.exports=r:"undefined"!=typeof module&&module.exports&&"undefined"!=typeof window?module.exports=s():"function"==typeof define&&define.amd?define("isMobile",[],a.isMobile=s()):a.isMobile=s()}(this);

alert(isMobile.any ? 'Mobile' : 'Not mobile');

This particular browser sniffing code is that of a library called isMobile.

Option 2 : window.orientation

Test if window.orientation is defined :

var isMobile = window.orientation > -1;
alert(isMobile ? 'Mobile' : 'Not mobile');

Note

Not all touchscreen devices are mobile and vice versa. So, if you want to implement something specifically for touchscreen, you shouldn't test if your browser is run on a mobile device but rather whether the devices has touchscreen support :

var hasTouchscreen = 'ontouchstart' in window;
alert(hasTouchscreen ? 'has touchscreen' : 'doesn\'t have touchscreen');

What do I need to do to make this function wait for the result of the promise?

Use async/await (NOT Part of ECMA6, but available for Chrome, Edge, Firefox and Safari since end of 2017, see canIuse)
MDN

    async function waitForPromise() {
        // let result = await any Promise, like:
        let result = await Promise.resolve('this is a sample promise');
    }

Added due to comment: An async function always returns a Promise, and in TypeScript it would look like:

    async function waitForPromise(): Promise<string> {
        // let result = await any Promise, like:
        let result = await Promise.resolve('this is a sample promise');
    }

From selenium/webdriver/support/wait.py

driver = ...
from selenium.webdriver.support.wait import WebDriverWait
element = WebDriverWait(driver, 10).until(
    lambda x: x.find_element_by_id("someId"))

The best solution is to add to your apache .htaccess file the following line after RewriteEngine On

RewriteRule ^sitemap\.xml$ sitemap.php [L]

and then simply having a file sitemap.php in your root folder that would be normally accessible via http://www.yoursite.com/sitemap.xml, the default URL where all search engines will firstly search.

The file sitemap.php shall start with

<?php
//Saturday, 11 January 2020 @kevin

header('Content-type: text/xml');
echo '<?xml version="1.0" encoding="UTF-8"?>';
?>
<urlset
      xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9
            http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">

<url>
  <loc>https://www.yoursite.com/</loc>
  <lastmod>2020-01-08T13:06:14+00:00</lastmod>
  <priority>1.00</priority>
</url>


</urlset>

it works :)

If the following command does not work,

npm install --save-dev @angular-devkit/build-angular

then move to the project folder and run this command:

npm install --save @angular-devkit/build-angular

I've found in www.laughing-buddha.net/php/lib/dirlist/ a function that returns an array containing a list of a directory's contents.

Also look at php.net http://es.php.net/manual/es/ref.filesystem.php where you'll find additional functions for working with files in php.

Agreed with jcadcell comments, but had to use JDK 1.8 because my eclipse need that. So I just copied the MSVCR71.DLL from jdk1.6 and pasted into jdk1.8 in both the folder jdk1.8.0_121\bin and jdk1.8.0_121\jre\bin

and it Worked .... Wow... Thanks :)

I wrote xdpyprobe program which is intended for this purpose. Unlike xset, xdpyinfo and other general tools, it does not do any extra actions (just checks X server and exits) and it may not produce any output (if "-q" option is specified).

Get-ChildItem -r | ? {$_.psiscontainer -eq $false} | ? {gc $_.pspath |select-string -pattern "dummy"}

This will give you the full details of all files

This's weird!

I tested the solutions both sizeThatFits: and [webView stringByEvaluatingJavaScriptFromString:@"document.body.scrollHeight"] are NOT working for me.

However, I found an interesting easy way to get the right height of webpage content. Currently, I used it in my delegate method scrollViewDidScroll:.

CGFloat contentHeight = scrollView.contentSize.height - CGRectGetHeight(scrollView.frame);

Verified in iOS 9.3 Simulator/Device, good luck!

EDIT:

Background: The html content is calculated by my string variable and HTTP content template, loaded by method loadHTMLString:baseURL:, no registered JS scripts there.

As pointed right by many other users. It's because there may be whitespace or a newline character.

Consider the following code, it removes all the duplicate characters from a given string.

#include <bits/stdc++.h>
using namespace std;

int main() {
    int t;
    cin>>t;
    cin.ignore(); //Notice that this cin.ignore() is really crucial for any extra whitespace or newline character
    while(t--){
        vector<int> v(256,0);
        string s;
        getline(cin,s);
        string s2;
        for(int i=0;i<s.size();i++){
            if (v[s[i]]) continue;
            else{
                s2.push_back(s[i]);
                v[s[i]]++;
            }
        }
        cout<<s2<<endl;
    }
    return 0;
}

So, You get the point that it will ignore those unwanted inputs and will get the job done.

Oh my, C vs C++, a great way to start a flame war. :)

I think C is better for driver and embedded code.

C++ has some great features that C doesn't have, but many of the object oriented features of C++ can cause monumental coding messes when people write code with non-obvious side-effects that occur behinds the scenes. Crazy code can be hidden in constructors, destructors, virtual functions, ... The beauty of C code is the language does nothing non-obvious behind your back, thus you can read the code and not have to look up at every constructor and destructor and so on. A lot of the problem is bad coding practices by SOME people.

My perfect language would be a combination of C99 plus a minimal subset of safer C++ capabilities that adds ZERO (or near zero) compiler overhead to the binary output. Perfect additions would be class encapsulation and naming concepts of data and functions.

You could also do it this way.

specialRegex = /[^A-Z a-z0-9]/ specialRegex.test('test!') // evaluates to true Because if its not a capital letter, lowercase letter, number, or space, it could only be a special character

For large text, the full text index is much faster. But you can full text index varchar(max)as well.

Try this

frame$twohouses <- ifelse(frame$data>1, 2, 1)
 frame
   data twohouses
1     0         1
2     1         1
3     2         2

@cms way is the more recent, suggested in MS website, but I had a hard problem to solve, with both method posted here, now I post the solution for all!

problem: if you use an url like this: www.somesite.it/?p=1500 in some case you get an internal server error (500), although in web browser this www.somesite.it/?p=1500 perfectly work.

solution: you have to move out parameters, working code is:

using System.Net;
//...
using (WebClient client = new WebClient ()) 
{
    client.QueryString.Add("p", "1500"); //add parameters
    string htmlCode = client.DownloadString("www.somesite.it");
    //...
}

In sublime text editor, file -> reopen with encoding -> choose the correct encoding.

Generally, the encoding is auto-detected, but if not, you can use the above method.

CrossAlignment.center is using the Width of the 'Child Widget' to center itself and hence gets rendered at the start of the page.

When the Column is centered within the page body's 'Center Container' , the CrossAlignment.center uses page body's 'Center' as reference and renders the widget at the center of the page

Code

import 'package:flutter/material.dart';

void main() => runApp(MaterialApp(
    title:"DynamicWidgetApp",
    home:DynamicWidgetApp(),

));

class DynamicWidgetApp extends StatefulWidget{
  @override
  DynamicWidgetAppState createState() => DynamicWidgetAppState();
  }

class  DynamicWidgetAppState extends State<DynamicWidgetApp>{
  @override
  Widget build(BuildContext context) {

    return Scaffold(
      body: Center(
     //Removing body:Center will change the reference
    // and render the widget at the start of the page 
        child: Column(
            mainAxisAlignment : MainAxisAlignment.center,
            crossAxisAlignment : CrossAxisAlignment.center,
            children: [
              Text("My Centered Widget"),
            ]
          ),
      ),
      floatingActionButton: FloatingActionButton(
        // onPressed: ,
        child : Icon(Icons.add),
      ),
      );
    }
  }

X_train_test_V=pd.DataFrame(X_train_test)
X_valid=pd.DataFrame(X_valid)

X_train, X_test, y_train, y_test = train_test_split(X_train_test, y_train_test, test_size=tst_size, random_state=13903)

Another solution (without a wrapper) would be to set the form to display: table, which would make it act like a table so it would have the width of its largest child, and then apply margin: 0 auto to center it.

form {
    display: table;
    margin: 0 auto;
}

Use this wise advice from LLVM team:

"Turn Predicate Loops into Predicate Functions"

See:

http://llvm.org/docs/CodingStandards.html#turn-predicate-loops-into-predicate-functions

What I don't understand is what's the point of having a byte? Why not say 8 bits?

Apart from the technical point that a byte isn't necessarily 8 bits, the reasons for having a term is simple human nature:

• economy of effort (aka laziness) - it is easier to say "byte" rather than "eight bits"

• tribalism - groups of people like to use jargon / a private language to set them apart from others.

Just go with the flow. You are not going to change 50+ years of accumulated IT terminology and cultural baggage by complaining about it.

FWIW - the correct term to use when you mean "8 bits independent of the hardware architecture" is "octet".

StringUtils.isBlank() will also check for null, whereas this:

String foo = getvalue("foo");
if (foo.isEmpty())

will throw a NullPointerException if foo is null.

ADb used to work fine for me for a week. But now suddenly today it says the machine actively refused connection.

fix:

step 1: go check you phone's IP Adress once again, it keeps changing.
step 2: If it changed. Just use that new IP to connect.

Hope it helped someone :)

I'm not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let's isolate the problem. Consider following code:

var display = Array();
display[0] = "none";
display[1] = "block";
display[2] = "none";

console.log( JSON.stringify(display) );

This will print:

["none","block","none"]

This is how JSON actually serializes array. However what you want to see is something like:

{"0":"none","1":"block","2":"none"}

To get this format you want to serialize object, not array. So let's rewrite above code like this:

var display2 = {};
display2["0"] = "none";
display2["1"] = "block";
display2["2"] = "none";

console.log( JSON.stringify(display2) );

This will print in the format you want.

You can play around with this here: http://jsbin.com/oDuhINAG/1/edit?js,console

You can't really compare NA with another value, so using == would not work. Consider the following:

NA == NA
# [1] NA

You can just change your comparison from == to %in%:

ifelse(is.na(test$time) | test$type %in% "A", NA, "1")
# [1] NA  "1" NA  "1"

Regarding your other question,

I could get this to work with my existing code if I could somehow change the result of is.na(test$type) to return FALSE instead of TRUE, but I'm not sure how to do that.

just use ! to negate the results:

!is.na(test$time)
# [1]  TRUE  TRUE FALSE  TRUE

With SQL Server 2012 (11.x) and later and Azure SQL Database, you can also have "fetch_row_count_expression", you can also have ORDER BY clause along with this.

USE AdventureWorks2012;  
GO  
-- Specifying variables for OFFSET and FETCH values    
DECLARE @skip int = 0  , @take int = 8;  
SELECT DepartmentID, Name, GroupName  
FROM HumanResources.Department  
ORDER BY DepartmentID ASC   
    OFFSET @skip ROWS   
    FETCH NEXT @take ROWS ONLY; 

https://docs.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql?view=sql-server-ver15

Note OFFSET Specifies the number of rows to skip before it starts to return rows from the query expression. It is NOT the starting row number. So, it has to be 0 to include first record.

You need to use the local set command below:

local set

git config user.email [email protected]
git config user.name 'Mahmoud Zalt'

local get

git config --get user.email
git config --get user.name

The local config file is in the project directory: .git/config.

global set

git config --global user.email [email protected]
git config --global user.name 'Mahmoud Zalt'

global get

git config --global --get user.email
git config --global --get user.name

The global config file in in your home directory: ~/.gitconfig.

Remember to quote blanks, etc, for example: 'FirstName LastName'

I follow one of the advice above and indeed it works. In summary while you download Anaconda on Ubuntu using the advice given above can help you to 'create' environments. The default when you download Spyder in my case is: (base) smith@ubuntu ~$. After you create the environment, i.e. fenics and activate it with $ conda activate fenics the prompt change to (fenics) smith@ubuntu ~$. Then you launch Spyder from this prompt, i.e $ spyder and your system open the Spyder IDE, and you can write fenics code on it. Remember every time you open a terminal your system open the default prompt. You have to activate your environment where your package is and the prompt change to it i.e. (fenics).

Dietel and Dietel have a nice way of explaining fields vs variables.

“Together a class’s static variables and instance variables are known as its fields.” (Section 6.3)

“Variables should be declared as fields only if they’re required for use in more than one method of the class or if the program should save their values between calls to the class’s methods.” (Section 6.4)

So a class's fields are its static or instance variables - i.e. declared with class scope.

Reference - Dietel P., Dietel, H. - Java™ How To Program (Early Objects), Tenth Edition (2014)

You just need to run query

db.test.find(
{"shapes.color": "red"}, 
{shapes: {$elemMatch: {color: "red"}}});

output of this query is

{
    "_id" : ObjectId("562e7c594c12942f08fe4192"),
    "shapes" : [ 
        {"shape" : "circle", "color" : "red"}
    ]
}

as you expected it'll gives the exact field from array that matches color:'red'.

I had the issue with PeriodicTask classes in django-celery, while their names showed up fine when starting the celery worker every execution triggered:

KeyError: u'my_app.tasks.run'

My task was a class named 'CleanUp', not just a method called 'run'.

When I checked table 'djcelery_periodictask' I saw outdated entries and deleting them fixed the issue.

If you want to see what you you have inside an object in your web app, then use the json pipe in a component HTML template, for example:

<li *ngFor="let obj of myArray">{{obj | json}}</li>

Tested and valid using Angular 4.3.2.

If you have a List, you can use .Contains(yourObject), if you're just looking for it existing (like a where). Otherwise look at Linq .Any() extension method.

getText(): Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.

getAttribute(String attrName): Get the value of a the given attribute of the element. Will return the current value, even if this has been modified after the page has been loaded. More exactly, this method will return the value of the given attribute, unless that attribute is not present, in which case the value of the property with the same name is returned (for example for the "value" property of a textarea element). If neither value is set, null is returned. The "style" attribute is converted as best can be to a text representation with a trailing semi-colon. The following are deemed to be "boolean" attributes, and will return either "true" or null: async, autofocus, autoplay, checked, compact, complete, controls, declare, defaultchecked, defaultselected, defer, disabled, draggable, ended, formnovalidate, hidden, indeterminate, iscontenteditable, ismap, itemscope, loop, multiple, muted, nohref, noresize, noshade, novalidate, nowrap, open, paused, pubdate, readonly, required, reversed, scoped, seamless, seeking, selected, spellcheck, truespeed, willvalidate Finally, the following commonly mis-capitalized attribute/property names are evaluated as expected: "class" "readonly"

getText() return the visible text of the element.

getAttribute(String attrName) returns the value of the attribute passed as parameter.

<?php
session_start();

$message1 = "A message";
$message2 = "Another message";

$_SESSION['firstMessage'] = $message1;
$_SESSION['secondMessage'] = $message2; 
?>

Stores the sessions on page 1 then on page 2 do

<?php
session_start();

echo $_SESSION['firstMessage'];
echo $_SESSION['secondMessage'];
?>

You may be looking for position: fixed.

Works everywhere except IE6 and many mobile devices.

You can open the other file and type :r file_to_be_copied_from. Or you can buffer. Or go to the first file, go on the line you want to copy, type "qY, go to the file you want to paste and type "qP.

"buffer_name, copies to the buffer. Y is yank and P is put. Hope that helps!

If you don't have the correct .map file and you don't want to edit lines in bootstrap.css you can create a dummy .map file.

In my case I was seeing the error:

GET /bootstrap.css.map not found.

So I created an empty bootstrap.css.map in the /public directory and the error stopped.

Select SUM(CASE When CPayment='Cash' Then CAmount Else 0 End ) as CashPaymentAmount,
       SUM(CASE When CPayment='Check' Then CAmount Else 0 End ) as CheckPaymentAmount
from TableOrderPayment
Where ( CPayment='Cash' Or CPayment='Check' ) AND CDate<=SYSDATETIME() and CStatus='Active';

OR makes sense (from readability point of view), when there are less values to be compared. IN is useful esp. when you have a dynamic source, with which you want values to be compared.

Another alternative is to use a JOIN with a temporary table.
I don't think performance should be a problem, provided you have necessary indexes.

I've seen goto used correctly but the situations are normaly ugly. It is only when the use of goto itself is so much less worse than the original. @Johnathon Holland the poblem is you're version is less clear. people seem to be scared of local variables:

void foo()
{
    bool doAsuccess = doA();
    bool doBsuccess = doAsuccess && doB();
    bool doCsuccess = doBsuccess && doC();

    if (!doCsuccess)
    {
        if (doBsuccess)
            undoB();
        if (doAsuccess)
            undoA();
    }
}

And I prefer loops like this but some people prefer while(true).

for (;;)
{
    //code goes here
}

what you are doing here is reading one character at a time from the input stream and assume that all the characters between " " represent a word. BUT it's unlikely to be a " " after the last word, so that's probably why it does not work:

"word1 word2 word2EOF"

I found this great tutorial regarding SVN when I was looking up the website of the author of the OpenCV 2 Computer Vision Application Programming Cookbook and I thought I should share.

He has a tutorial on how to use SVN and what the phrases 'trunk', 'tag' and 'branch' mean.

Cited directly from his tutorial:

The current version of your software project, on which your team is currently working is usually located under a directory called trunk. As the project evolves, the developer updates that version fix bugs, add new features) and submit his changes under that directory.

At any given point in time, you may want to freeze a version and capture a snapshot of the software as it is at this stage of the development. This generally corresponds to the official versions of your software, for example, the ones you will deliver to your clients. These snapshots are located under the tags directory of your project.

Finally, it is often useful to create, at some point, a new line of development for your software. This happens, for example, when you wish to test an alternative implementation in which you have to modify your software but you do not want to submit these changes to the main project until you decide if you adopt the new solution. The main team can then continue to work on the project while other developer work on the prototype. You would put these new lines of development of the project under a directory called branches.

$this->container->get('security.token_storage')->getToken()->getUser();

The closest equivalent to Java's toString is to implement __str__ for your class. Put this in your class definition:

def __str__(self):
     return "foo"

You may also want to implement __repr__ to aid in debugging.

Hey, this might not be the most ideal solution, but it works for me. I ended up creating a Python-Markdown LaTeX extension.

https://github.com/justinvh/Markdown-LaTeX

It adds support for inline math and text expressions using a $math$ and %text% syntax. The extension is a preprocessor that will use latex/dvipng to generate pngs for the respective equations/text and then base64 encode the data to inline the images directly, rather than have external images.

The data is then put in a simple-delimited cache file that encodes the expression to the base64 representation. This limits the number of times latex actually has to be run.

Here is an example:

%Hello, world!% This is regular text, but this: $y = mx + b$ is not.

The output:

$ markdown -x latex test.markdown
<p><img class='latex-inline math-false' alt='Hello, world!' id='Helloworld' src='data:image/png;base64,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'> This is regular text, but this: <img class='latex-inline math-true' alt='y = mx + b' id='ymxb' src='data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAFIAAAAOBAMAAABOTlYkAAAAMFBMVEX///9ERETu7u4yMjK6urp2dnZUVFSIiIjMzMwQEBDc3NwiIiJmZmaYmJiqqqoAAADS00rKAAAAAXRSTlMAQObYZgAAAOtJREFUKM9jYCAACsCk4wYGgiABTLInEKuS+QGxKvkVGBj47jBwI8tcffI84e45BoZ7GVcLECo9751iWLeSoRPITBQEggMMDBy9sxj2MDgz8DIE8yCpPMxwjWFBGUMMkpFcbAEMvxjKGLgYxIE8NkHBiYIyQMY+hmoGhi0Mdsi2czawbGCQBTJ+ILvzE0MaA9MHIIWwnWE9A+sBpk8LGDgmMCnAVXJNYPgCJHhRQvUiA/cDXoECZx4DXoSZTBtYgaaEPw5AVnkOGBRc5xTcbsReQrL9+nWwyxbgC88DcJZ+QygDcYD1+QPiFAIAtLA8KPZOGFEAAAAASUVORK5CYII='> is not.</p>

As you can see it is a verbose output, but that really isn't an issue since you're already using Markdown :)

It's probably because you are directly or indirectly through a library call accessing a NULL pointer. In this particular case, it looks like you've jumped to a NULL address, which is a b bit hairier.

In my experience, the easiest way to track these down are to run it with a debugger, and dump a stack trace.

Alternatively, you can do it "by hand" and add lots of logging until you can track down exactly which function (and possibly LOC) this violation occurred in.

Take a look at Stack Tracer, which might help you improve your debugging.

As of Python 3.2, released Nov 2011, the smtplib has a new function send_message instead of just sendmail, which makes dealing with To/CC/BCC easier. Pulling from the Python official email examples, with some slight modifications, we get:

# Import smtplib for the actual sending function
import smtplib

# Import the email modules we'll need
from email.message import EmailMessage

# Open the plain text file whose name is in textfile for reading.
with open(textfile) as fp:
    # Create a text/plain message
    msg = EmailMessage()
    msg.set_content(fp.read())

# me == the sender's email address
# you == the recipient's email address
# them == the cc's email address
# they == the bcc's email address
msg['Subject'] = 'The contents of %s' % textfile
msg['From'] = me
msg['To'] = you
msg['Cc'] = them
msg['Bcc'] = they


# Send the message via our own SMTP server.
s = smtplib.SMTP('localhost')
s.send_message(msg)
s.quit()

Using the headers work fine, because send_message respects BCC as outlined in the documentation:

send_message does not transmit any Bcc or Resent-Bcc headers that may appear in msg

With sendmail it was common to add the CC headers to the message, doing something such as:

msg['Bcc'] = [email protected]

Or

msg = "From: [email protected]" +
      "To: [email protected]" +
      "BCC: [email protected]" +
      "Subject: You've got mail!" +
      "This is the message body"

The problem is, the sendmail function treats all those headers the same, meaning they'll get sent (visibly) to all To: and BCC: users, defeating the purposes of BCC. The solution, as shown in many of the other answers here, was to not include BCC in the headers, and instead only in the list of emails passed to sendmail.

The caveat is that send_message requires a Message object, meaning you'll need to import a class from email.message instead of merely passing strings into sendmail.

This will give you the last day of the month:

function lastday($month = '', $year = '') {
   if (empty($month)) {
      $month = date('m');
   }
   if (empty($year)) {
      $year = date('Y');
   }
   $result = strtotime("{$year}-{$month}-01");
   $result = strtotime('-1 second', strtotime('+1 month', $result));
   return date('Y-m-d', $result);
}

And the first Day:

function firstDay($month = '', $year = '')
{
    if (empty($month)) {
      $month = date('m');
   }
   if (empty($year)) {
      $year = date('Y');
   }
   $result = strtotime("{$year}-{$month}-01");
   return date('Y-m-d', $result);
} 

It seems like there is permission on mobile keypad setting, so the easiest way to do this is:

editText.setFilters(new InputFilter[]{new InputFilter.AllCaps()});

hope this will work

Bootstrap 4

The display (hidden/visible) classes are changed in Bootstrap 4. To hide on the xs viewport use:

d-none d-sm-block

Also see: Missing visible-** and hidden-** in Bootstrap v4

Yeah, you can't constrain the iframe itself with height and width. You should put a div around it. If you control the content in the iframe, you can put some JS within the iframe content that will tell the parent to scroll the div when the touch event is received.

like this:

The JS:

setTimeout(function () {
var startY = 0;
var startX = 0;
var b = document.body;
b.addEventListener('touchstart', function (event) {
    parent.window.scrollTo(0, 1);
    startY = event.targetTouches[0].pageY;
    startX = event.targetTouches[0].pageX;
});
b.addEventListener('touchmove', function (event) {
    event.preventDefault();
    var posy = event.targetTouches[0].pageY;
    var h = parent.document.getElementById("scroller");
    var sty = h.scrollTop;

    var posx = event.targetTouches[0].pageX;
    var stx = h.scrollLeft;
    h.scrollTop = sty - (posy - startY);
    h.scrollLeft = stx - (posx - startX);
    startY = posy;
    startX = posx;
});
}, 1000);

The HTML:

<div id="scroller" style="height: 400px; width: 100%; overflow: auto;">
<iframe height="100%" id="iframe" scrolling="no" width="100%" id="iframe" src="url" />
</div>

If you don't control the iframe content, you can use an overlay over the iframe in a similar manner, but then you can't interact with the iframe contents other than to scroll it - so you can't, for example, click links in the iframe.

It used to be that you could use two fingers to scroll within an iframe, but that doesn't work anymore.

Update: iOS 6 broke this solution for us. I've been attempting to get a new fix for it, but nothing has worked yet. In addition, it is no longer possible to debug javascript on the device since they introduced Remote Web Inspector, which requires a Mac to use.

After looking at your method, I used this method to solve it.

class Register(forms.Form):
    username = forms.CharField(label='???', max_length=32)
    email = forms.EmailField(label='??', max_length=64)
    password = forms.CharField(label="??", min_length=6, max_length=16)
    captcha = forms.CharField(label="???", max_length=4)

def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    for field_name in self.fields:
        field = self.fields.get(field_name)
        self.fields[field_name].widget.attrs.update({
            "placeholder": field.label,
            'class': "input-control"
        })

Old:

maxrss states the maximum available memory for the process. 0 means that no limit is put upon the process. What you probably want is unshared data usage ru_idrss.

New: It seems that the above does not actually work, as the kernel does not fill most of the values. What does work is to get the information from proc. Instead of parsing it oneself though, it is easier to use libproc (part of procps) as follows:

// getrusage.c
#include <stdio.h>
#include <proc/readproc.h>

int main() {
  struct proc_t usage;
  look_up_our_self(&usage);
  printf("usage: %lu\n", usage.vsize);
}

Compile with "gcc -o getrusage getrusage.c -lproc"

Spring Docs explain that

In proxy mode (which is the default), only external method calls coming in through the proxy are intercepted. This means that self-invocation, in effect, a method within the target object calling another method of the target object, will not lead to an actual transaction at runtime even if the invoked method is marked with @Transactional.

Consider the use of AspectJ mode (see mode attribute in table below) if you expect self-invocations to be wrapped with transactions as well. In this case, there will not be a proxy in the first place; instead, the target class will be weaved (that is, its byte code will be modified) in order to turn @Transactional into runtime behavior on any kind of method.

Another way is user BeanSelfAware

For all those of you that try to remove the separating line of the tabWidget, here is an example project (and its respective tutorial), that work great for customizing the tabs and thus removing problems when tabs are at bottom. Eclipse Project: android-custom-tabs ; Original explanation: blog; Hope this helped.

Devise uses some generators to generate views and stuff it needs into your application. If you have run this generator, you can easily undo it with

    $(this).find("td:gt(0)").each(function(){

Expanding from Andriy M, and yes you can do this from a file, even one with multiple lines

@echo off
setlocal EnableExtensions EnableDelayedExpansion
set "INTEXTFILE=test.txt"
set "OUTTEXTFILE=test_out.txt"
set "SEARCHTEXT=bath"
set "REPLACETEXT=hello"

for /f "delims=" %%A in ('type "%INTEXTFILE%"') do (
    set "string=%%A"
    set "modified=!string:%SEARCHTEXT%=%REPLACETEXT%!"
    echo !modified!>>"%OUTTEXTFILE%"
)

del "%INTEXTFILE%"
rename "%OUTTEXTFILE%" "%INTEXTFILE%"
endlocal

EDIT

Thanks David Nelson, I have updated the script so it doesn't have the hard coded values anymore.

Two steps for a complete local development:

1. Provide the path to the local directory that contains the package.

{
  "name": "baz",
  "dependencies": {
    "bar": "file:../foo/bar"
  }
}

2. Symlink the package folder

   cd ~/projects/node-redis    # go into the package directory
   npm link                    # creates global link
   cd ~/projects/node-bloggy   # go into some other package directory.
   npm link redis              # link-install the package
   

Your code concatenates three strings, then converts the result to a number.

You need to convert each variable to a number by calling parseFloat() around each one.

total = parseFloat(myInt1) + parseFloat(myInt2) + parseFloat(myInt3);

Here's how to setup a scrollview using Xcode 11

1 - Add scrollview and set top,bottom,leading and trailing constraints

2 - Add a Content View to the scrollview, drag a connection to the Content Layout Guide and select Leading, Top, Bottom and Trailing. Make sure to set its' values to 0 or the constants you want.

3 - Drag from the Content View to the Frame Layout Guide and select Equal Widths

4 - Set a height constraint constant to the Content View

You can use \n to concatenate words and then apply this style to container div.

    This _x000D_
  text _x000D_
  contains _x000D_
  new lines._x000D_
</p>

Add this function to your <script></script> and call from where ever you want in that <script></script>

<script>

function GetNow(){
    var currentdate = new Date(); 
    var datetime = currentdate.getDate() + "-"
            + (currentdate.getMonth()+1)  + "-" 
            + currentdate.getFullYear() + " "  
            + currentdate.getHours() + ":"  
            + currentdate.getMinutes() + ":" 
            + currentdate.getSeconds();
    return datetime;
}

window.alert(GetNow());

</script>

or you may simply use the Jquery which provides formatting facilities also:-

window.alert(Date.parse(new Date()).toString('yyyy-MM-dd H:i:s'));

I love the second option. It resolves all issues in one go.

basically i use this in one of our apps: we want to overlay a playicon over a frame of a video:

                             GraphicsUnit.Pixel);
            canvas.DrawImage(playbutton,
                             (bitmap.Width / 2) - (playbutton.Width / 2),
                             (bitmap.Height / 2) - (playbutton.Height / 2));
            canvas.Save();

Pelo Hyper-V:

private PerformanceCounter theMemCounter = new PerformanceCounter(
    "Hyper-v Dynamic Memory VM",

    BigDecimal a = new BigDecimal("10.12345");
    System.out.println(toPrecision(a, 2));
}

private static BigDecimal toPrecision(BigDecimal dec, int precision) {
    String plain = dec.movePointRight(precision).toPlainString();
    return new BigDecimal(plain.substring(0, plain.indexOf("."))).movePointLeft(precision);
}

About answer 3 removing only the last \n off string code :

if (!s.empty() && s[s.length()-1] == '\n') {
    s.erase(s.length()-1);
}

Will the if condition not fail if the string is really empty ?

Is it not better to do :

if (!s.empty())
{
    if (s[s.length()-1] == '\n')
        s.erase(s.length()-1);
}

If you really want to match only the dot, then StringComparison.Ordinal would be fastest, as there is no case-difference.

"Ordinal" doesn't use culture and/or casing rules that are not applicable anyway on a symbol like a ..

This explains the whole thing:

The HTTP Content-Security-Policy (CSP) upgrade-insecure-requests directive instructs user agents to treat all of a site's insecure URLs (those served over HTTP) as though they have been replaced with secure URLs (those served over HTTPS). This directive is intended for web sites with large numbers of insecure legacy URLs that need to be rewritten.

The upgrade-insecure-requests directive is evaluated before block-all-mixed-content and if it is set, the latter is effectively a no-op. It is recommended to set one directive or the other, but not both.

The upgrade-insecure-requests directive will not ensure that users visiting your site via links on third-party sites will be upgraded to HTTPS for the top-level navigation and thus does not replace the Strict-Transport-Security (HSTS) header, which should still be set with an appropriate max-age to ensure that users are not subject to SSL stripping attacks.

If they are in the same controller class, it would be:

foreach ( $characters as $character) {
    $num += $this->getFactorial($index) * $index;
    $index ++;
}

Otherwise you need to create a new instance of the class, and call the method, ie:

$controller = new MyController();
foreach ( $characters as $character) {
    $num += $controller->getFactorial($index) * $index;
    $index ++;
}

If you want a "capture/streamer in a box" component, there are several out there as others have mentioned.

If you want to get down to the low-level control over it all, you'll need to use DirectShow as thealliedhacker points out. The best way to use DirectShow in C# is through the DirectShow.Net library - it wraps all of the DirectShow COM APIs and includes many useful shortcut functions for you.

In addition to capturing and streaming, you can also do recording, audio and video format conversions, audio and video live filters, and a whole lot of stuff.

Microsoft claims DirectShow is going away, but they have yet to release a new library or API that does everything that DirectShow provides. I suspect many of the latest things they have released are still DirectShow under the hood. Because of its status at Microsoft, there aren't a whole lot of books or references on it other than MSDN and what you can find on forums. Last year when we started a project using it, the best book on the subject - Programming Microsoft DirectShow - was out of print and going for around $350 for a used copy!

I think that the solution of @Azimuts (https://stackoverflow.com/a/33375677/6503697) is for HTTP only connection. For FTPS connection you can use Bouncy Castle with org.apache.commons.net.ftp.FTPSClient without the need for rewrite FTPS protocol.

I have a program running on JRE 1.6.0_04 and I can not update the JRE.

The program has to connect to an FTPS server that work only with TLS 1.2 (IIS server).

I struggled for days and finally I have understood that there are few versions of bouncy castle library right in my use case: bctls-jdk15on-1.60.jar and bcprov-jdk15on-1.60.jar are ok, but 1.64 versions are not.

The version of apache commons-net is 3.1 .

Following is a small snippet of code that should work:

import java.io.ByteArrayOutputStream;
import java.security.SecureRandom;
import java.security.Security;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.commons.net.ftp.FTP;
import org.apache.commons.net.ftp.FTPReply;
import org.apache.commons.net.ftp.FTPSClient;
import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.jsse.provider.BouncyCastleJsseProvider;
import org.junit.Test;


public class FtpsTest {

// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {

    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    public void checkClientTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }

    public void checkServerTrusted(java.security.cert.X509Certificate[] certs, String authType) {
    }
} };

@Test public void test() throws Exception {


    Security.insertProviderAt(new BouncyCastleProvider(), 1);
    Security.addProvider(new BouncyCastleJsseProvider());


    SSLContext sslContext = SSLContext.getInstance("TLS", new BouncyCastleJsseProvider());
    sslContext.init(null, trustAllCerts, new SecureRandom());
    org.apache.commons.net.ftp.FTPSClient ftpClient = new FTPSClient(sslContext);
    ByteArrayOutputStream out = null;
    try {

        ftpClient.connect("hostaname", 21);
        if (!FTPReply.isPositiveCompletion(ftpClient.getReplyCode())) {
            String msg = "Il server ftp ha rifiutato la connessione.";
            throw new Exception(msg);
        }
        if (!ftpClient.login("username", "pwd")) {
            String msg = "Il server ftp ha rifiutato il login con username:  username  e pwd:  password  .";
            ftpClient.disconnect();
            throw new Exception(msg);
        }


        ftpClient.enterLocalPassiveMode();
        ftpClient.setFileType(FTP.BINARY_FILE_TYPE);
        ftpClient.setDataTimeout(60000);
        ftpClient.execPBSZ(0); // Set protection buffer size
        ftpClient.execPROT("P"); // Set data channel protection to private
        int bufSize = 1024 * 1024; // 1MB
        ftpClient.setBufferSize(bufSize);
        out = new ByteArrayOutputStream(bufSize);
        ftpClient.retrieveFile("remoteFileName", out);
        out.toByteArray();
    }
    finally {
        if (out != null) {
            out.close();
        }
        ftpClient.disconnect();

    }

}

}

Simplify in a similar fashion to what you had in mind:

DO
$do$
BEGIN
   IF NOT EXISTS (
      SELECT FROM pg_catalog.pg_roles  -- SELECT list can be empty for this
      WHERE  rolname = 'my_user') THEN

      CREATE ROLE my_user LOGIN PASSWORD 'my_password';
   END IF;
END
$do$;

(Building on @a_horse_with_no_name's answer and improved with @Gregory's comment.)

Unlike, for instance, with CREATE TABLE there is no IF NOT EXISTS clause for CREATE ROLE (up to at least pg 12). And you cannot execute dynamic DDL statements in plain SQL.

Your request to "avoid PL/pgSQL" is impossible except by using another PL. The DO statement uses plpgsql as default procedural language. The syntax allows to omit the explicit declaration:

DO [ LANGUAGE lang_name ] code
...
lang_name
The name of the procedural language the code is written in. If omitted, the default is plpgsql.

My preferred method is to use PadRight. Instead of clearing the line first, this clears the remainder of the line after the new text is displayed, saving a step:

Console.CursorTop = 0;
Console.CursorLeft = 0;
Console.Write("Whatever...".PadRight(Console.BufferWidth));

I always use this code, which print the year to second in a tuple

import datetime

now = datetime.datetime.now()

time_now = (now.year, now.month, now.day, now.hour, now.minute, now.second)

print(time_now)

Should be also noted that there might be problems in IE<=9 when using script defer in certain situations. More on this: https://github.com/h5bp/lazyweb-requests/issues/42

This might be overkill - but be careful doing anything which relies on the extension of PHP files being .php - what if someone comes along later and adds handlers for .php4 or even .html so they're handled by PHP. You might be better off serving files out of those directories from a different instance of Apache or something, which only serves static content.

In the shell, you can't execute more than one statement at a time:

>>> x = 5
y = 6
SyntaxError: multiple statements found while compiling a single statement

You need to execute them one by one:

>>> x = 5
>>> y = 6
>>>

When you see multiple statements are being declared, that means you're seeing a script, which will be executed later. But in the interactive interpreter, you can't do more than one statement at a time.

You can use bookmarklets (javascript code in a bookmark) - this also means they sync across devices.

I have loads - I prefix the name with zzz, so they are eazy to type in to the address bar and show in drop down predictions.

To get them to operate on a page you need to go to the page and then in the address bar type the bookmarklet name - this will cause the bookmarklet to execute in the context of the page.

edit

Just to highlight - for this to work, the bookmarklet name must be typed into the address bar while the page you want to operate in is being displayed - if you go off to select the bookmarklet in some other way the page context gets lost, and the bookmarklet operates on a new empty page.

I use zzzpocket - send to pocket. zzztwitter tweet this page zzzmail email this page zzzpressthis send this page to wordpress zzztrello send this page to trello and more...

and it works in chrome whatever platform I am currently logged on to.

I also faced same problem but it worked when I used 'MJPG' instead of 'XVID'

I used

fourcc = cv2.VideoWriter_fourcc(*'MJPG')

instead of

fourcc = cv2.VideoWriter_fourcc(*'XVID')

Try adding C:\path\to\java\jre\bin to your system environment variable PATH and run again. That worked for me!

I solved this today by putting my JavaScript at the bottom of the response HTML.

I had an AJAX request that returned a bunch of HTML that was displayed in an overlay. I needed to attach a click event to a button in the returned response HTML/overlay. On a normal page, I would wrap my JavaScript in a "window.onload" or "$(document).ready" so that it would attach the event handler to the DOM object after the DOM for the new overlay had been rendered, but because this was an AJAX response and not a new page load, that event never happened, the browser never executed my JavaScript, my event handler never got attached to the DOM element, and my new piece of functionality didn't work. Again, I solved my "executing JavaScript in an AJAX response problem" by not using "$(document).ready" in the head of the document, but by placing my JavaScript at the end of the document and having it run after the HTML/DOM had been rendered.

I have string that displays UTF-8 encoded characters

There is no such thing in .NET. The string class can only store strings in UTF-16 encoding. A UTF-8 encoded string can only exist as a byte[]. Trying to store bytes into a string will not come to a good end; UTF-8 uses byte values that don't have a valid Unicode codepoint. The content will be destroyed when the string is normalized. So it is already too late to recover the string by the time your DecodeFromUtf8() starts running.

Only handle UTF-8 encoded text with byte[]. And use UTF8Encoding.GetString() to convert it.

If the date is given in a fixed form, you can simply use a regular expression to extract the date and "datetime.datetime.strptime" to parse the date:

import re
from datetime import datetime

match = re.search(r'\d{4}-\d{2}-\d{2}', text)
date = datetime.strptime(match.group(), '%Y-%m-%d').date()

Otherwise, if the date is given in an arbitrary form, you can't extract it easily.

ctrl + shift + A => open pop window to select options, select to spaces to convert all tabs as space, or to tab to convert all spaces as tab.

To add to the other excellent advice, I'd also be mindful of the following:

For some CPUs (e.g. Intel Core i5 range with TurboBoost), the temperature (and number of cores currently being used, as well as thier utilisation percent) affects the clock speed. Since CPUs are dynamically clocked, this can affect your results. For example, if you have a single-threaded application, the maximum clock speed (with TurboBoost) is higher than for an application using all cores. This can therefore interfere with comparisons of single and multi-threaded performance on some systems. Bear in mind that the temperature and volatages also affect how long Turbo frequency is maintained.

Perhaps a more fundamentally important aspect that you have direct control over: make sure you're measuring the right thing! For example, if you're using System.nanoTime() to benchmark a particular bit of code, put the calls to the assignment in places that make sense to avoid measuring things which you aren't interested in. For example, don't do:

long startTime = System.nanoTime();
//code here...
System.out.println("Code took "+(System.nanoTime()-startTime)+"nano seconds");

Problem is you're not immediately getting the end time when the code has finished. Instead, try the following:

final long endTime, startTime = System.nanoTime();
//code here...
endTime = System.nanoTime();
System.out.println("Code took "+(endTime-startTime)+"nano seconds");

Well, as it was said before, you can't GROUP by literals, I think that you are confused cause you can ORDER by 1, 2, 3. When you use functions as your columns, you need to GROUP by the same expression. Besides, the HAVING clause is wrong, you can only use what is in the agreggations. In this case, your query should be like this:

SELECT 
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound,
MAX(qvalues.rid) MaxRid
FROM batchinfo join qvalues 
ON batchinfo.rowid=qvalues.rowid
WHERE LEN(datapath)>4
GROUP BY 
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound

There is absolutely nothing wrong with the code you've written. Both some_function and someVar should be accessible, in case they were available in the context where anonymous

function() { some_function(someVar); } 

was created.

Check if the alert gives you the value you've been looking for, be sure it will be accessible in the scope of anonymous function (unless you have more code that operates on the same someVar variable next to the call to addEventListener)

var someVar; 
someVar = some_other_function();
alert(someVar);
someObj.addEventListener("click", function(){
    some_function(someVar);
}, false);

1. Press the Apps menu button on your Android mobile phone device. It will display icons of all the apps installed on your mobile phone device. Press Settings.

2. Press Apps. (Pressing on Apps button will list down all the apps installed on your mobile phone.

3. Browse the Apps list and press on the app called "Launcher 3". (Launcher 3 is an app and it will be listed in the App list whenever you access Settings > Apps in your android phone).

4. Pressing on the "Launcher 3" app will open the "App info screen" which will show some details pertaining to that app. On this App info screen, you will find buttons like "Force Stop", "Uninstall", "Clear Data" and "Clear Cache" etc.

5. In Android Marshmallow (i.e. Android 6.0) choose Settings > Apps > Launcher3 > STORAGE. Press "Clear Cache". If this fails, press "Clear data". This will eventually restore functionality, but all custom shortcuts will be lost.

Restart the phone and its done. All the home screens along with app shortcuts will appear again and your mobile phone is at your service again.

I hope it explains well on how to solve the launcher problem in Android. Worked for me.

This solution worked for me using the android sdk v19:

//get the image button by id
ImageButton myImg = (ImageButton) findViewById(R.id.some_id);

//get drawable from image button
GradientDrawable drawable = (GradientDrawable) myImg.getDrawable();

//set color as integer
//can use Color.parseColor(color) if color is a string
drawable.setColor(color)

app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
    var data = {
        "fruit": {
            "apple": req.params.fruitName,
            "color": req.params.fruitColor
        }
    }; 

    send.json(data);
});

If that doesn't work, try using console.log(req.params) to see what it is giving you.

After further investigating on PSExec tool, I think I got the answer. I need to add -i option to tell PSExec to launch process on remote in interactive mode:

PSExec \\RPC001 -i -u myID -p myPWD PowerShell C:\script\StartPS.ps1 par1 par2

Without -i, powershell.exe is running on the remote in waiting mode. Interesting point is that if I run a simple bat (without PS in bat), it works fine. Maybe this is something special for PS case? Welcome comments and explanations.

You can directly set the content type like below:

res.writeHead(200, {'Content-Type': 'text/plain'});

For reference go through the nodejs Docs link.

You can also initialize data members at the point you declare them:

class another_example{
public:
    another_example();
    ~another_example();
private:
    int m_iInteger=10;
    double m_dDouble=10.765;
};

I use this form pretty much exclusively, although I have read some people consider it 'bad form', perhaps because it was only recently introduced - I think in C++11. To me it is more logical.

Another useful facet to the new rules is how to initialize data-members that are themselves classes. For instance suppose that CDynamicString is a class that encapsulates string handling. It has a constructor that allows you specify its initial value CDynamicString(wchat_t* pstrInitialString). You might very well use this class as a data member inside another class - say a class that encapsulates a windows registry value which in this case stores a postal address. To 'hard code' the registry key name to which this writes you use braces:

class Registry_Entry{
public:
    Registry_Entry();
    ~Registry_Entry();
    Commit();//Writes data to registry.
    Retrieve();//Reads data from registry;
private:
    CDynamicString m_cKeyName{L"Postal Address"};
    CDynamicString m_cAddress;
};

Note the second string class which holds the actual postal address does not have an initializer so its default constructor will be called on creation - perhaps automatically setting it to a blank string.

Use the built in type cast functionality, simply type

$realArray = (array)$stdClass;

from openpyxl import load_workbook

sheets = load_workbook(excel_file, read_only=True).sheetnames

For a 5MB Excel file I'm working with, load_workbook without the read_only flag took 8.24s. With the read_only flag it only took 39.6 ms. If you still want to use an Excel library and not drop to an xml solution, that's much faster than the methods that parse the whole file.

The problem I had was when trying to reset my repository. I wanted to delete all history and commit nothing. However, you have to add at least SOMETHING to commit, so I just created an empty text file, git add . and then git commit -m "Reset repository".

How about this? (requires y non-negative, so don't use this in the rare case where y is a variable with no non-negativity guarantee)

q = (x > 0)? 1 + (x - 1)/y: (x / y);

I reduced y/y to one, eliminating the term x + y - 1 and with it any chance of overflow.

I avoid x - 1 wrapping around when x is an unsigned type and contains zero.

For signed x, negative and zero still combine into a single case.

Probably not a huge benefit on a modern general-purpose CPU, but this would be far faster in an embedded system than any of the other correct answers.

$characters = '123456789';
$charactersLength = strlen($characters);
$randomString = '';
for ($i = 0; $i < 6; $i++) {
    $randomString .= $characters[rand(0, $charactersLength - 1)];
}
$pin=$randomString; 

Used zoom-master/jquery.zoom.js. The zoom for the image worked perfectly. Here is a link to the page. http://www.jacklmoore.com/zoom/

 <script>
    $(document).ready(function(){
        $('#ex1').zoom();

    });
</script>

I would use a bound service to do that and communicate with it by implementing a listener in my activity. So if your app implements myServiceListener, you can register it as a listener in your service after you have bound with it, call listener.onUpdateUI from your bound service and update your UI in there!

You can use Jasypt to encrypt properties, so you could have your property like this:

db.password=ENC(XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx+hNPrJyQT88=)

Jasypt allows you to encrypt your properties using different algorithms, once you get the encrypted property you put inside the ENC(...). For instance, you can encrypt this way through Jasypt using the terminal:

encrypted-pwd$ java -cp ~/.m2/repository/org/jasypt/jasypt/1.9.2/jasypt-1.9.2.jar  org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input="contactspassword" password=supersecretz algorithm=PBEWithMD5AndDES

----ENVIRONMENT-----------------

Runtime: Oracle Corporation Java HotSpot(TM) 64-Bit Server VM 24.45-b08



----ARGUMENTS-------------------

algorithm: PBEWithMD5AndDES
input: contactspassword
password: supersecretz



----OUTPUT----------------------

XcBjfjDDjxeyFBoaEPhG14wEzc6Ja+Xx+hNPrJyQT88=

To easily configure it with Spring Boot you can use its starter jasypt-spring-boot-starter with group ID com.github.ulisesbocchio

Keep in mind, that you will need to start your application using the same password you used to encrypt the properties. So, you can start your app this way:

mvn -Djasypt.encryptor.password=supersecretz spring-boot:run

Or using the environment variable (thanks to spring boot relaxed binding):

export JASYPT_ENCRYPTOR_PASSWORD=supersecretz
mvn spring-boot:run

You can check below link for more details:

https://www.ricston.com/blog/encrypting-properties-in-spring-boot-with-jasypt-spring-boot/

To use your encrypted properties in your app just use it as usual, use either method you like (Spring Boot wires the magic, anyway the property must be of course in the classpath):

Using @Value annotation

@Value("${db.password}")
private String password;

Or using Environment

@Autowired
private Environment environment;

public void doSomething(Environment env) {
    System.out.println(env.getProperty("db.password"));
}

Update: for production environment, to avoid exposing the password in the command line, since you can query the processes with ps, previous commands with history, etc etc. You could:

• Create a script like this: touch setEnv.sh
• Edit setEnv.sh to export the JASYPT_ENCRYPTOR_PASSWORD variable

  #!/bin/bash

  export JASYPT_ENCRYPTOR_PASSWORD=supersecretz

• Execute the file with . setEnv.sh
• Run the app in background with mvn spring-boot:run &
• Delete the file setEnv.sh
• Unset the previous environment variable with: unset JASYPT_ENCRYPTOR_PASSWORD

I think sometimes stupid mistakes can give us this error.

<div id="#main"> <--- id with hashtag
    <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
</div>

To

<div id="main"> <--- id without hashtag
    <div id="mainActivity" v-component="{{currentActivity}}" class="activity"></div>
</div>

I needed this for something as simple as redirecting all http traffic from the default apache home page on my server to one served over https.

Since I'm still quite green when it comes to configuring apache, I prefer to avoid using mod_rewrite directly and instead went for something simpler like this:

<VirtualHost *:80>
  <Location "/">
     Redirect permanent "https://%{HTTP_HOST}%{REQUEST_URI}"
  </Location>
</VirtualHost>

<VirtualHost *:443>
  DocumentRoot "/var/www/html"
  SSLEngine on
  ...
</VirtualHost>

I like this because it allowed me to use apache variables and that way I didn't have to specify the actual host name since it's just an IP address without an associated domain name.

Combining what Dick Lucas says and adding a reset autoincremental from other StackOverFlow posts, i think this can work:

fun clearAndResetAllTables(): Boolean {
    val db = db ?: return false

    // reset all auto-incrementalValues
    val query = SimpleSQLiteQuery("DELETE FROM sqlite_sequence")

    db.beginTransaction()
    return try {
        db.clearAllTables()
        db.query(query)
        db.setTransactionSuccessful()
        true
    } catch (e: Exception){
        false
    } finally {
        db.endTransaction()
    }
}

Yes, you can safely pass an array as a parameter.

you can write a stored procedure like this:

CREATE PROCEDURE sanitize_TABLE()

BEGIN

#replace space with underscore

UPDATE Table SET FieldName = REPLACE(FieldName," ","_") WHERE FieldName is not NULL;

#delete dot

UPDATE Table SET FieldName = REPLACE(FieldName,".","") WHERE FieldName is not NULL;

#delete (

UPDATE Table SET FieldName = REPLACE(FieldName,"(","") WHERE FieldName is not NULL;

#delete )

UPDATE Table SET FieldName = REPLACE(FieldName,")","") WHERE FieldName is not NULL;

#raplace or delete any char you want

#..........................

END

In this way you have modularized control over table.

You can also generalize stored procedure making it, parametric with table to sanitoze input parameter

If I read this correctly, it will be a requirement to use semicolons to end TSQL statements. http://msdn.microsoft.com/en-us/library/ms143729%28v=sql.120%29.aspx

EDIT: I found a plug-in for SSMS 2008R2 that will format your script and add the semicolons. I think it is still in beta though...

What's not mentioned here is that option 1 allows you arbitrarily deep nesting of lists.

This shouldn't matter if you control the content/css, but if you're making a rich text editor it comes in handy.

For example, gmail, inbox, and evernote all allow creating lists like this:

With option 2 you cannot due that (you'll have an extra list item), with option 1, you can.

You will have to manually delete from the project explorer (your local machine hard drive), then delete the project in IntelliJ when it asks to re-open recent projects.

A solution without your indentation:

for path, dirs, files in os.walk(given_path):
  print path
  for f in files:
    print f

os.walk already does the top-down, depth-first walk you are looking for.

Ignoring the dirs list prevents the overlapping you mention.

Multi cursor edit is natively supported in Visual Studio starting from version 2017 Update 8. The following is an extract of the documentation:

• Ctrl + Alt + click : Add a secondary caret
• Ctrl + Alt + double-click : Add a secondary word selection
• Ctrl + Alt + click + drag : Add a secondary selection
• Shift + Alt + . : Add the next matching text as a selection
• Shift + Alt + ; : Add all matching text as selections
• Shift + Alt + , : Remove last selected occurrence
• Shift + Alt + / : Skip next matching occurrence
• Alt + click : Add a box selection
• Esc or click : Clear all selections

Some of those commands are also available in the Edit menu:

This is the error that is returned when the Windows Firewall blocks the port (out-going). We have a strict web server so the outgoing ports are blocked by default. All I had to do was to create a rule to allow the TCP port number in wf.msc.

@@IDENTITY Is a system function that returns the last-inserted identity value.

Use setState in your view to change employed property of state. This is example of React render engine.

 someFunctionWhichChangeParamEmployed(isEmployed) {
      this.setState({
          employed: isEmployed
      });
 }

 getInitialState() {
      return {
          employed: true
      }
 },

 render(){
    if (this.state.employed) {
        return (
            <div>
                <MyInput ref="job-title" name="job-title" />
            </div>
        );
    } else {
        return (
            <div>
                <span>Diff me!</span>
                <MyInput ref="unemployment-reason" name="unemployment-reason" />
                <MyInput ref="unemployment-duration" name="unemployment-duration" />
            </div>
        );
    }
}

Polymorphism: Polymorphism is the ability of an object to take on many forms. The most common use of polymorphism in OOP occurs when a parent class reference is used to refer to a child class object.

Dynamic Binding/Runtime Polymorphism :

Run time Polymorphism also known as method overriding. In this Mechanism by which a call to an overridden function is resolved at a Run-Time.

public class DynamicBindingTest {

    public static void main(String args[]) {
        Vehicle vehicle = new Car(); //here Type is vehicle but object will be Car
        vehicle.start();       //Car's start called because start() is overridden method
    }
}

class Vehicle {

    public void start() {
        System.out.println("Inside start method of Vehicle");
    }
}

class Car extends Vehicle {

    @Override
    public void start() {
        System.out.println("Inside start method of Car");
    }
}

Output:

Inside start method of Car

Static Binding /compile-time polymorphism:

Which method is to be called is decided at compile-time only.

public class StaticBindingTest {

    public static void main(String args[])  {
       Collection c = new HashSet();
       StaticBindingTest et = new StaticBindingTest();
       et.sort(c);

    }

    //overloaded method takes Collection argument
    public Collection sort(Collection c){
        System.out.println("Inside Collection sort method");
        return c;
    }


   //another overloaded method which takes HashSet argument which is sub class
    public Collection sort(HashSet hs){
        System.out.println("Inside HashSet sort method");

}

Output: Inside Collection sort metho

Related to @Steven Penny's answer, I also use wget. Furthermore, to decide which file to send the output to I use -O .

If you are using gitlabs another possibility for the url is:

wget "https://git.labs.your-server/your-repo/raw/master/<path-to-file>" -O <output-file>

Unless you have the certificate or you access from a trusted server for the gitlabs installation you need --no-check-certificate as @Kos said. I prefer that rather than modifying .wgetrc but it depends on your needs.

If it is a big file you might consider using -c option with wget. To be able to continue downloading the file from where you left it if the previous intent failed in the middle.

Package mlr includes createDummyFeatures for this purpose:

library(mlr)
df <- data.frame(var = sample(c("A", "B", "C"), 10, replace = TRUE))
df

#    var
# 1    B
# 2    A
# 3    C
# 4    B
# 5    C
# 6    A
# 7    C
# 8    A
# 9    B
# 10   C

createDummyFeatures(df, cols = "var")

#    var.A var.B var.C
# 1      0     1     0
# 2      1     0     0
# 3      0     0     1
# 4      0     1     0
# 5      0     0     1

This should do the trick

var start = $('#start_date').val();
var end = $('#end_date').val();

// end - start returns difference in milliseconds 
var diff = new Date(end - start);

// get days
var days = diff/1000/60/60/24;

Example

var start = new Date("2010-04-01"),
    end   = new Date(),
    diff  = new Date(end - start),
    days  = diff/1000/60/60/24;

days; //=> 8.525845775462964

According to my experince i can summarize :

1.The problem is mainly refering to syntax issues that can be occured on xml files.

2.You might copy the AndroidManifest.xml accidently to subfolders .

1.One file is an extension undefined .

After checking all of these Go to Project->Clean or just remove the /bin and /gen folders.

The code you provided would print the number of tabs, not the number of spaces. The below function should count the number of whitespace characters in a given string.

int countSpaces(String string) {
    int spaces = 0;
    for(int i = 0; i < string.length(); i++) {
        spaces += (Character.isWhitespace(string.charAt(i))) ? 1 : 0;
    }
    return spaces;
}

try this:

InputMethodManager imm = (InputMethodManager) getActivity()
            .getSystemService(Context.INPUT_METHOD_SERVICE);

    if (imm.isAcceptingText()) {
        writeToLog("Software Keyboard was shown");
    } else {
        writeToLog("Software Keyboard was not shown");
    }

Most programs will check the $EDITOR environment variable, so you can set that to the path of TextEdit in your bashrc. Git will use this as well.

How to do this:

• Add the following to your ~/.bashrc file:
  export EDITOR="/Applications/TextEdit.app/Contents/MacOS/TextEdit"
• or just type the following command into your Terminal:
  echo "export EDITOR=\"/Applications/TextEdit.app/Contents/MacOS/TextEdit\"" >> ~/.bashrc

If you are using zsh, use ~/.zshrc instead of ~/.bashrc.

UEFA internally provides their own LIVEX Api for their Broadcasting Partners. That one is perfect enough to develop the Applications by their partners for themselves.

I had the same issue, although the module that it was downloading was different. The only resolution to the problem is run the below command again:

npm install

The shortest and easiest answer is: you shouldn't vertically center things in webpages. HTML and CSS simply are not created with that in mind. They are text formatting languages, not user interface design languages.

That said, this is the best way I can think of. However, this will NOT WORK in Internet Explorer 7 and below!

<style>
  html, body {
    height: 100%;
  }
  #tableContainer-1 {
    height: 100%;
    width: 100%;
    display: table;
  }
  #tableContainer-2 {
    vertical-align: middle;
    display: table-cell;
    height: 100%;
  }
  #myTable {
    margin: 0 auto;
  }
</style>
<div id="tableContainer-1">
  <div id="tableContainer-2">
    <table id="myTable" border>
      <tr><td>Name</td><td>J W BUSH</td></tr>
      <tr><td>Proficiency</td><td>PHP</td></tr>
      <tr><td>Company</td><td>BLAH BLAH</td></tr>
    </table>
  </div>
</div>

Thats because its tied to the web view not the button. I had the same problem after implementing. The button had no affect but the page in the web view did.

Somehow postman didn't work for me. I had to use a chrome extension called RESTED which did work.

Note:drawRect and fillRect are different.

Draws the outline of the specified rectangle:

public void drawRect(int x,
        int y,
        int width,
        int height)

Fills the specified rectangle. The rectangle is filled using the graphics context's current color:

public abstract void fillRect(int x,
        int y,
        int width,
        int height)

exports.mailSend = (res, fileName, object1, object2, to, subject,   callback)=> {
var smtpTransport = nodemailer.createTransport('SMTP',{ //smtpTransport
host: 'hostname,

secureConnection: false,
//   tls: {
//     ciphers:'SSLv3'
// },

});
res.render(fileName, {

}, function (err, HTML) {

smtpTransport.sendMail({

  , function (err, responseStatus) {
      if(responseStatus)
    console.log("checking dta", responseStatus.message);

You must add secureConnection type in you code.

This is a tad old (OK, it's VERY old), but I'm doing the exact same thing right now. Here's a very simple solution that's working for me:

[DllImport("kernel32.dll", SetLastError = true)]
static extern bool AllocConsole();

[DllImport("kernel32.dll")]
static extern IntPtr GetConsoleWindow();

[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);

const int SW_HIDE = 0;
const int SW_SHOW = 5;

public static void ShowConsoleWindow()
{
    var handle = GetConsoleWindow();

    if (handle == IntPtr.Zero)
    {
        AllocConsole();
    }
    else
    {
        ShowWindow(handle, SW_SHOW);
    }
}

public static void HideConsoleWindow()
{
    var handle = GetConsoleWindow();
    ShowWindow(handle, SW_HIDE);
}

Make an update object with the property names including the necessary dot path. ("somekey."+ from OP's example), and then use that do the update.

//the modification that's requested
updateReq = { 
   param2 : "val2_new",
   param3 : "val3_new"   
}

//build a renamed version of the update request
var update = {};
for(var field in updateReq){
    update["somekey."+field] = updateReq[field];
}

//apply the update without modifying fields not originally in the update
db.collection.update({._id:...},{$set:update},{upsert:true},function(err,result){...});

There's also the NVL function

http://www.techonthenet.com/oracle/functions/nvl.php

In excel 2013 the object creation string is:

Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")

instead of the code in the answer above:

Dim fs,fname
Set fs=Server.CreateObject("Scripting.FileSystemObject")

Without using Async and Await Use this...

funCall(){    
     this.setState({...this.state.jasper, name: 'someothername'});
}

If you using with Async And Await use this...

async funCall(){
      await this.setState({...this.state.jasper, name: 'someothername'});
}

Try perl -MCPAN -e "upgrade /(.\*)/". It works fine for me.

I was getting e.data.indexOf is not a function error, after debugging it, I found that it was actually a TypeError, which meant, indexOf() being a function is applicable to strings, so I typecasted the data like the following and then used the indexOf() method to make it work

e.data.toString().indexOf('<stringToBeMatchedToPosition>')

Not sure if my answer was accurate to the question, but yes shared my opinion as i faced a similar kind of situation.

in addition to all answers please note that in sendmail.ini file:

auth_password=this-is-Not-your-Gmail-password

due to new google security concern, you should follow these steps to make an application password for this purpose:

1. go to https://accounts.google.com/ in security tab
2. turn two-step-verification on
3. go back to the security tab and make an App-password (in select-app drop-down menu you can choose 'other')

PHP 7+

As of PHP 7, you can just use the define() function to define a constant array :

define('ANIMALS', [
    'dog',
    'cat',
    'bird'
]);

echo ANIMALS[1]; // outputs "cat"

Here's a solution that works for environments that don't have the string library (Linux kernel, embedded systems, etc):

#define FILENAME ({ \
    const char* filename_start = __FILE__; \
    const char* filename = filename_start; \
    while(*filename != '\0') \
        filename++; \
    while((filename != filename_start) && (*(filename - 1) != '/')) \
        filename--; \
    filename; })

Now just use FILENAME instead of __FILENAME__. Yes, it's still a runtime thing but it works.

Based on your comments, we need to go over how the Bundling mechanism works in MVC.

Edit: Based on the comment below by VSDev, you need to ensure WebGrease is installed into your project. NuGet would be the easiest was to install this package.

When you set a bundle configuration (Example not from above to illustrate)

bundles.Add(new ScriptBundle("~/bundles/mainJs")
      .Include("~/Scripts/mainSite.js")
      .Include("~/Scripts/helperStuff.js");

You then, in your views, call something like @Scripts.Render("~/bundles/mainJs"). When your web.config is set into a debug compilation OR you explicitly turn off bundling using the following line in your BundleConfig.cs file

BundleTable.EnableOptimizations = false;

Then, in your view, you will see the following rendered out

<script src="/Scripts/mainSite.js" type="text/javascript"></script>
<script src="/Scripts/helperStuff.js" type="text/javascript"></script>

These are the individual items that made up our bundle, uncompressed and listed individually. The reason these list out individually in debug mode is so that you can debug your scripts and see them as you wrote them (actual variable names, etc).

Now, when we are not in a debug compilation and have not turned off the EnableOptimizations feature, MVC will combine those files in our bundles, compress (minify) them and output only a single script tag.

<script src="/bundles/mainJs?v=someBigLongNumber" type="text/javascript"></script>

Notice that the source is the same as the name of the bundle from the bundle configurations. Also, the number after the ?v= will change anytime you change a file in that bundle. This is to help prevent caching of old js and css files by the client browsers.

Your scripts are still there and being outputted, but they are being compressed and combined into a single file called /bundles/mainJs. This feature is present to

A) compress the files and reduce information being transmitted and,

B) reduce the number of calls to a website to retrieve the necessary content to render the page.

Nothing is missing, it sounds like everything is working as intended. In a production site, the minification makes these files almost impossible to read, thus why the minification does not take affect while debugging.

As to why the jQuery UI is still being a single JS file, ensure someone didn't hard code that into your layout view. As for the JS errors, it could be errors that are present on your development box or perhaps something did not compress correctly (however, in all of my MVC development, I have not seen a JS error because of bad minification).

I just found an alternate workaround. I have a big problem with the typedef approach which bit me today:

• The typedef requires an exact copy of the class name. If someone changes the class name but doesn't change the typedef then you will run into problems.

So I came up with a better solution using a very simple template.

template <class C>
struct MakeAlias : C
{ 
    typedef C BaseAlias;
};

So now, instead of

class Derived : public Base
{
private:
    typedef Base Super;
};

you have

class Derived : public MakeAlias<Base>
{
    // Can refer to Base as BaseAlias here
};

In this case, BaseAlias is not private and I've tried to guard against careless usage by selecting an type name that should alert other developers.

This code may be helpful for you.

Modern versions of Swift use DispatchQueue.main.async to dispatch to the main thread:

DispatchQueue.main.async { 
  // your code here
}

To dispatch after on the main queue, use:

DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
  // your code here
}

Older versions of Swift used:

dispatch_async(dispatch_get_main_queue(), {
  let delegateObj = UIApplication.sharedApplication().delegate as YourAppDelegateClass
  delegateObj.addUIImage("yourstring")
})

I was looking for the same thing and I just found this list

https://developers.facebook.com/docs/reference/api/errors/

The tuple function takes only one argument which has to be an iterable

tuple([iterable])

Return a tuple whose items are the same and in the same order as iterable‘s items.

Try making 3,4 an iterable by either using [3,4] (a list) or (3,4) (a tuple)

For example

a_list.append(tuple((3, 4)))

will work

Start with:

find . -name '*.log.*.zip' -a -mtime +1

You may not need a regex, try:

 find . -name '*.log.*-*-*.zip' -a -mtime +1

You will want the +1 in order to match 1, 2, 3 ...

I have discovered that NotePad++ now also creates a subfolder at the file location, called nppBackup. So if your file lived in a folder called c:/thisfolder have a look to see if there's a folder called c:/thisfolder/nppBackup.

Occasionally I couldn't find the backup in AppData\Roaming\Notepad++\backup, but I found it in nppBackup.

No, there's no built-in way to convert a class like you say. The simplest way to do this would be to do what you suggested: create a DerivedClass(BaseClass) constructor. Other options would basically come out to automate the copying of properties from the base to the derived instance, e.g. using reflection.

The code you posted using as will compile, as I'm sure you've seen, but will throw a null reference exception when you run it, because myBaseObject as DerivedClass will evaluate to null, since it's not an instance of DerivedClass.

Everything, written above is correct. Just a sample to insert into the app and change {YOUR APP ID} to actual app id, taken from iTunesconnect to show the Review page. Please note, as it was commented above, that it is not working on the Simulator - just the device.
- Correcting because of ios 7 changes.

NSString * appId = @"{YOUR APP ID}";
NSString * theUrl = [NSString  stringWithFormat:@"itms-apps://itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?id=%@&onlyLatestVersion=true&pageNumber=0&sortOrdering=1&type=Purple+Software",appId];
if ([[UIDevice currentDevice].systemVersion integerValue] > 6) theUrl = [NSString stringWithFormat:@"itms-apps://itunes.apple.com/app/id%@",appId];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:theUrl]];

In ES6, in case you want to dynamically pass the field as a string:

function getFields(array, field) {
    return array.map(a => a[field]);
}

let result = getFields(array, 'foo');

How about doing it like this:

1) show popup with form

2) submit form using AJAX

3) in AJAX server side code, render response that will either:

• show popup with form with validations or just a message
• close the popup (and maybe redirect you to new page)

just use -

if(!a) // if a is negative,undefined,null,empty value then...
{
    // do whatever
}
else {
    // do whatever
}

this works because of the == difference from === in javascript, which converts some values to "equal" values in other types to check for equality, as opposed for === which simply checks if the values equal. so basically the == operator know to convert the "", null, undefined to a false value. which is exactly what you need.

Using one of the subsets method in this question

    new KeyValuePair<string, int>("A", 1),

    new KeyValuePair<string, int>("D", 2),

This package backports all features and APIs added in the pickle module in Python 3.8.3, including the PEP 574 additions. It should work with Python 3.5, 3.6 and 3.7.

Basic usage is similar to the pickle module, except that the module to be imported is pickle5:

Leonbloy's answer is quite complete. I would only add the special case in which one needs to get the last inserted value from within a PL/pgSQL function where OPTION 3 doesn't fit exactly.

For example, if we have the following tables:

CREATE TABLE person(
   id serial,
   lastname character varying (50),
   firstname character varying (50),
   CONSTRAINT person_pk PRIMARY KEY (id)
);

CREATE TABLE client (
    id integer,
   CONSTRAINT client_pk PRIMARY KEY (id),
   CONSTRAINT fk_client_person FOREIGN KEY (id)
       REFERENCES person (id) MATCH SIMPLE
);

If we need to insert a client record we must refer to a person record. But let's say we want to devise a PL/pgSQL function that inserts a new record into client but also takes care of inserting the new person record. For that, we must use a slight variation of leonbloy's OPTION 3:

INSERT INTO person(lastname, firstname) 
VALUES (lastn, firstn) 
RETURNING id INTO [new_variable];

Note that there are two INTO clauses. Therefore, the PL/pgSQL function would be defined like:

CREATE OR REPLACE FUNCTION new_client(lastn character varying, firstn character varying)
  RETURNS integer AS
$BODY$
DECLARE
   v_id integer;
BEGIN
   -- Inserts the new person record and retrieves the last inserted id
   INSERT INTO person(lastname, firstname)
   VALUES (lastn, firstn)
   RETURNING id INTO v_id;

   -- Inserts the new client and references the inserted person
   INSERT INTO client(id) VALUES (v_id);

   -- Return the new id so we can use it in a select clause or return the new id into the user application
    RETURN v_id;
END;
$BODY$
  LANGUAGE plpgsql VOLATILE;

Now we can insert the new data using:

SELECT new_client('Smith', 'John');

or

SELECT * FROM new_client('Smith', 'John');

And we get the newly created id.

new_client

I have tried both ways, and from the Edit|Advanced menu, and they are not doing anything to my source code. Other options like line indent are working. What could be wrong? – Chucky Jul 12 '13 at 11:06

Sometimes if it doesnt work, try to select a couple lines above and below or the whole block of code (whole function, whole cycle, whole switch, etc.), so that it knows how to indent.

Like for example if you copy/paste something into a case statement of a switch and it has wrong indentation, you need to select the text + the line with the case statement above to get it to work.

The name of the inputs must be the same to belong to the same group. Then the others will be automatically deselected when one is clicked.

It might be that the package "Combinations" is not updated anymore and does not work with a recent version of R (I was also unable to install it on R 2.13.1 on windows). The package "combinat" installs without problem for me and might be a solution for you depending on what exactly you're trying to do.

I usually write a macro like this:

#define UNUSED(x) (void)(x)

You can use this macro for all your unused parameters. (Note that this works on any compiler.)

For example:

void f(int x) {
    UNUSED(x);
    ...
}

The simplest short form to me is something like:

#find web forms in my project except in compilation directories
(gci -recurse -path *.aspx,*.ascx).fullname -inotmatch '\\obj\\|\\bin\\'

And if you need more complex logic then use a filter:

  filter Filter-DirectoryBySomeLogic{
  
      param(
      [Parameter(Mandatory=$true,ValueFromPipeline=$true)]

Here is a version based on the accepted answer. It fixes two problems...

1. Improper disposing of the images.
2. Maintaining the aspect ratio of the image.

I found this tool to be fast and effective for both JPG and PNG files.

private static FileInfo CreateThumbnailImage(string imageFileName, string thumbnailFileName)
{
    const int thumbnailSize = 150;
    using (var image = Image.FromFile(imageFileName))
    {
        var imageHeight = image.Height;
        var imageWidth = image.Width;
        if (imageHeight > imageWidth)
        {
            imageWidth = (int) (((float) imageWidth / (float) imageHeight) * thumbnailSize);
            imageHeight = thumbnailSize;
        }
        else
        {
            imageHeight = (int) (((float) imageHeight / (float) imageWidth) * thumbnailSize);
            imageWidth = thumbnailSize;
        }

        using (var thumb = image.GetThumbnailImage(imageWidth, imageHeight, () => false, IntPtr.Zero))
            //Save off the new thumbnail
            thumb.Save(thumbnailFileName);
    }

    return new FileInfo(thumbnailFileName);
}

Crude, but it works on our system:

This is copied from my answer to another very similar post, hope it can help:

1) Start with maximum number of threads a system can support:

int Num_Threads =  thread::hardware_concurrency();

2) For an efficient threadpool implementation, once threads are created according to Num_Threads, it's better not to create new ones, or destroy old ones (by joining). There will be performance penalty, might even make your application goes slower than the serial version.

Each C++11 thread should be running in their function with an infinite loop, constantly waiting for new tasks to grab and run.

Here is how to attach such function to the thread pool:

int Num_Threads = thread::hardware_concurrency();
vector<thread> Pool;
for(int ii = 0; ii < Num_Threads; ii++)
{  Pool.push_back(thread(Infinite_loop_function));}

3) The Infinite_loop_function

This is a "while(true)" loop waiting for the task queue

void The_Pool:: Infinite_loop_function()
{
    while(true)
    {
        {
            unique_lock<mutex> lock(Queue_Mutex);

            condition.wait(lock, []{return !Queue.empty() || terminate_pool});
            Job = Queue.front();
            Queue.pop();
        }
        Job(); // function<void()> type
    }
};

4) Make a function to add job to your Queue

void The_Pool:: Add_Job(function<void()> New_Job)
{
    {
        unique_lock<mutex> lock(Queue_Mutex);
        Queue.push(New_Job);
    }
    condition.notify_one();
}

5) Bind an arbitrary function to your Queue

Pool_Obj.Add_Job(std::bind(&Some_Class::Some_Method, &Some_object));

Once you integrate these ingredients, you have your own dynamic threading pool. These threads always run, waiting for job to do.

I apologize if there are some syntax errors, I typed these code and and I have a bad memory. Sorry that I cannot provide you the complete thread pool code, that would violate my job integrity.

Edit: to terminate the pool, call the shutdown() method:

XXXX::shutdown(){
{
    unique_lock<mutex> lock(threadpool_mutex);
    terminate_pool = true;} // use this flag in condition.wait

    condition.notify_all(); // wake up all threads.

    // Join all threads.
    for(std::thread &every_thread : thread_vector)
    {   every_thread.join();}

    thread_vector.clear();  
    stopped = true; // use this flag in destructor, if not set, call shutdown() 
}

Update 2020: how they made it work while avoiding XSS attacks

GitHub appears to use two security approaches, this is a good article: https://digi.ninja/blog/svg_xss.php see also: https://security.stackexchange.com/questions/148507/how-to-prevent-xss-in-svg-file-upload

• show SVG inside <img tag, which prevents scripts from running, e.g. on READMEs: https://github.com/cirosantilli/test-git-web-interface/tree/8e394cdb012cba4bcf55ebdb89f36872b4c6c12a

• use Content-Security-Policy: default-src 'none'; style-src 'unsafe-inline'; sandbox. This prevents the script from running even in raw which contains the raw SVG file: https://raw.githubusercontent.com/cirosantilli/test-git-web-interface/8e394cdb012cba4bcf55ebdb89f36872b4c6c12a/svg-foreignObject.svg

  You can see the header with curl -vvv. The regular github.com pages also have a content-security-policy, but it is much larger.

Update 2017

A GitHub dev is currently looking into this: https://github.com/github/markup/issues/556#issuecomment-306103203

Update 2014-12: GitHub now renders SVG on blob show, so I don't see any reason why not to render on README renderings:

• https://github.com/blog/1902-svg-viewing-diffing
• https://github.com/cirosantilli/test/blob/2144a93333be144152e8b0d4144b77b211afce63/svg.svg

Also note that that SVG does have an XSS attempt but it does not run: https://raw.githubusercontent.com/cirosantilli/test/2144a93333be144152e8b0d4144b77b211afce63/svg.svg

The billion laugh SVG does make Firefox 44 Freeze, but Chromium 48 is OK: https://github.com/cirosantilli/web-cheat/blob/master/svg-billion-laughs.svg

Petah mentioned that blobs are fine because the SVG is inside an iframe.

Possible rationale for GitHub not serving SVG images

• general XML vulnerabilities. E.g. opening a billion laughs exploit just made Firefox crash my system. Firefox bug with exploit attached: https://bugzilla.mozilla.org/page.cgi?id=voting/user.html. Same on Chromium: https://code.google.com/p/chromium/issues/detail?id=231562

• SVG XSS scripting: while most browsers don't run scripts when the SVG is embedded with img, it seems that this is not required by the standards, so maybe GitHub is playing it safe.

  Browsers do run it if you open the SVG directly (but it appears that GitHub never shows images directly on the github.com domain) or if it is inline (which are currently completely removed by GitHub), so those cases shouldn't be a security concern. Relevant links:

  • spec: http://www.w3.org/TR/SVG/script.html
  • interactive SVG demo: http://www.w3.org/TR/SVG/images/script/script01.svg

The following questions asks about the risks of SVG in general: https://security.stackexchange.com/questions/11384/exploits-or-other-security-risks-with-svg-upload

use FileInputStream's readLine() method to read and parse the returned String to int using Integer.parseInt() method.

The traditional way is to have a Makefile in each of the subdirectories (part1, part2, etc.) allowing you to build them independently. Further, have a Makefile in the root directory of the project which builds everything. The "root" Makefile would look something like the following:

all:
    +$(MAKE) -C part1
    +$(MAKE) -C part2
    +$(MAKE) -C part3

Since each line in a make target is run in its own shell, there is no need to worry about traversing back up the directory tree or to other directories.

I suggest taking a look at the GNU make manual section 5.7; it is very helpful.

Ok, adding to the answers stated you might be also looking for

IEnumerable<string> m_oEnum = Enumerable.Empty<string>();

or

IEnumerable<string> m_oEnum = new string[]{};

Create a list of lists:

with open("/path/to/file") as file:
    lines = []
    for line in file:
        # The rstrip method gets rid of the "\n" at the end of each line
        lines.append(line.rstrip().split(","))

We were receiving the same. The exception was

Stacktrace: at Microsoft.Office.Interop.Excel._Workbook.SaveAs(Object Filename, Object FileFormat, Object Password, Object WriteResPassword, Object ReadOnlyRecommended, Object CreateBackup, XlSaveAsAccessMode AccessMode, Object ConflictResolution, Object AddToMru, Object TextCodepage, Object Text VisualLayout, Object Local)`

with an inner exception of

Exception from HRESULT: 0x800A03EC 2012-11-01 10:37:59`

We were able to resolve the problem with information from this post, which I quote here for convenience...

1. Login to the server as a administrator.
2. Go to "Start" -> "Run" and enter "taskmgr"
3. Go to the process tab in task manager and check "Show Processes from all users"
4. If there are any "Excel.exe" entries on the list, right click on the entry and select "End Process"
5. Close task manager.
6. Go to "Start" -> "Run" and enter "services.msc"
7. Stop the service automating Excel if it is running.
8. Go to "Start" -> "Run" and enter "dcomcnfg"
9. This will bring up the component services window, expand out "Console Root" -> "Computers" -> "DCOM Config"
10. Find "Microsoft Excel Application" in the list of components.
11. Right click on the entry and select "Properties"
12. Go to the "Identity" tab on the properties dialog.
13. Select "The interactive user."
14. Click the "OK" button.
15. Switch to the services console
16. Start the service automating Excel
17. Test you application again.

Pure JS

txt_name.value

txt_name.onkeyup = e=> alert(txt_name.value);

<input type="text" id="txt_name" />

Yes, throwing an exception from the failed constructor is the standard way of doing this. Read this FAQ about Handling a constructor that fails for more information. Having a init() method will also work, but everybody who creates the object of mutex has to remember that init() has to be called. I feel it goes against the RAII principle.

Sadly, this is not possible by default to use section as another user suggested, since a section is only available to the immediate child of a View.

What works however is implementing and redefining the section in every view, meaning:

section Head
{
    @RenderSection("Head", false)
}

This way every view can implement a head section, not just the immediate children. This only works partly though, especially with multiple partials the troubles begin (as you have mentioned in your question).

So the only real solution to your problem is using the ViewBag. The best would probably be a seperate collection (list) for CSS and scripts. For this to work, you need to ensure that the List used is initialized before any of the views are executed. Then you can can do things like this in the top of every view/partial (without caring if the Scripts or Styles value is null:

ViewBag.Scripts.Add("myscript.js");
ViewBag.Styles.Add("mystyle.css");

In the layout you can then loop through the collections and add the styles based on the values in the List.

@foreach (var script in ViewBag.Scripts)
{
    <script type="text/javascript" src="@script"></script>
}
@foreach (var style in ViewBag.Styles)
{
    <link href="@style" rel="stylesheet" type="text/css" />
}

I think it's ugly, but it's the only thing that works.

******UPDATE**** Since it starts executing the inner views first and working its way out to the layout and CSS styles are cascading, it would probably make sense to reverse the style list via ViewBag.Styles.Reverse().

This way the most outer style is added first, which is inline with how CSS style sheets work anyway.

EDIT: Because this keeps getting commented on, we all know that we shouldn't do this. The question was how do I do it, not should I do it.

Add this into your for mobile devices. Then do your widths in percentages and you'll be fine:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />

Add this in for devices that can't use viewport too:

<meta name="HandheldFriendly" content="true" />

You can comma-separate shadows:

box-shadow: inset 0 2px 0px #dcffa6, 0 2px 5px #000;

Notepad++ works just fine, although I choose to stick with Notepad, -m, or even sometimes the built-in "edit."

The problem you are encountering using Notepad++ is related to how Git is launching the editor executable. My solution to this is to set environment variable EDITOR to a batch file, rather than the actual editor executable, that does the following:

start /WAIT "E:\PortableApps\Notepad++Portable\Notepad++Portable.exe" %*

/WAIT tells the command line session to halt until the application exits, thus you will be able to edit to your heart's content while Git happily waits for you. %* passes all arguments to the batch file through to Notepad++.

C:\src> echo %EDITOR%
C:\tools\runeditor.bat
