I was getting this same warning everytime I was doing 'maven clean'. I found the solution :

Step - 1 Right click on your project in Eclipse

Step - 2 Click Properties

Step - 3 Select Maven in the left hand side list.

Step - 4 You will notice "pom.xml" in the Active Maven Profiles text box on the right hand side. Clear it and click Apply.

Below is the screen shot :

Hope this helps. :)

so my idea is take advantage of the current model:

(function(){_x000D_

  _x000D_
   var app = angular.module('way', [])_x000D_
   app.controller('Decision', Decision);_x000D_
_x000D_
   Decision.$inject = [];     _x000D_
_x000D_
   function Decision(){_x000D_
     var vm = this;_x000D_
     vm.checkItOut = _register;_x000D_
_x000D_
     function _register(newOption){_x000D_
       console.log('should I stay or should I go');_x000D_

I'm not a WCF expert but I'm wondering if you aren't running into a DDOS protection on IIS. I know from experience that if you run a bunch of simultaneous connections from a single client to a server at some point the server stops responding to the calls as it suspects a DDOS attack. It will also hold the connections open until they time-out in order to slow the client down in his attacks.

Multiple connection coming from different machines/IP's should not be a problem however.

There's more info in this MSDN post:

My edit got rejected, so I'm attaching how to handle merging changes from a remote branch here.

If you have to do this after an incorrect merge, you can do something like this:

# If you did a git pull and it broke something, do this first
# Find the one before the merge, copy the SHA1
git reflog
git reset --hard <sha1>

# Get remote updates but DONT auto merge it
git fetch github 

# Checkout to your mainline so your branch is correct.
git checkout develop 

# Make a new branch where you'll be applying matches
git checkout -b manual-merge-github-develop

# Apply your patches
git checkout --patch github/develop path/to/file
...

# Merge changes back in
git checkout develop
git merge manual-merge-github-develop # optionally add --no-ff

# You'll probably have to
git push -f # make sure you know what you're doing.

Describe Formatted/Extended will show the data definition of the table in hive

hive> describe Formatted dbname.tablename;

The easiest way is to put the declaration and definition in the same file, but it may cause over-sized excutable file. E.g.

class Foo
{
public:
template <typename T> void some_method(T t) {//...}
}

Also, it is possible to put template definition in the separate files, i.e. to put them in .cpp and .h files. All you need to do is to explicitly include the template instantiation to the .cpp files. E.g.

// .h file
class Foo
{
public:
template <typename T> void some_method(T t);
}

// .cpp file
//...
template <typename T> void Foo::some_method(T t) 
{//...}
//...

template void Foo::some_method<int>(int);
template void Foo::some_method<double>(double);

I had installed CUDA 10.1 and CUDNN 7.6 by mistake. You can use following configurations (This worked for me - as of 9/10). :

• Tensorflow-gpu == 1.14.0
• CUDA 10.1
• CUDNN 7.6
• Ubuntu 18.04

But I had to create symlinks for it to work as tensorflow originally works with CUDA 10.

sudo ln -s /opt/cuda/targets/x86_64-linux/lib/libcublas.so /opt/cuda/targets/x86_64-linux/lib/libcublas.so.10.0
sudo cp /usr/lib/x86_64-linux-gnu/libcublas.so.10 /usr/local/cuda-10.1/lib64/
sudo ln -s /usr/local/cuda-10.1/lib64/libcublas.so.10 /usr/local/cuda-10.1/lib64/libcublas.so.10.0
sudo ln -s /usr/local/cuda/targets/x86_64-linux/lib/libcusolver.so.10 /usr/local/cuda/lib64/libcusolver.so.10.0
sudo ln -s /usr/local/cuda/targets/x86_64-linux/lib/libcurand.so.10 /usr/local/cuda/lib64/libcurand.so.10.0
sudo ln -s /usr/local/cuda/targets/x86_64-linux/lib/libcufft.so.10 /usr/local/cuda/lib64/libcufft.so.10.0
sudo ln -s /usr/local/cuda/targets/x86_64-linux/lib/libcudart.so /usr/local/cuda/lib64/libcudart.so.10.0
sudo ln -s /usr/local/cuda/targets/x86_64-linux/lib/libcusparse.so.10 /usr/local/cuda/lib64/libcusparse.so.10.0

And add the following to my ~/.bashrc -

export PATH=/usr/local/cuda/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH
export PATH=/usr/local/cuda-10.1/bin:$PATH

I created a Eclipse plugin, which can count the lines of source code. It support Kotlin, Java, Java Script, JSP, XML, C/C++, C#, and many other file types.

Please take a look at it. Any feedback would be appreciated!

@Michiel is correct to create a button but the code for ActionScript 3 it is a little different - where movieClipName is the name of your 'button'.

movieClipName.addEventListener(MouseEvent.CLICK, callLink);
function callLink:void {
  var url:String = "http://site";
  var request:URLRequest = new URLRequest(url);
  try {
    navigateToURL(request, '_blank');
  } catch (e:Error) {
    trace("Error occurred!");
  }

Easy way of doing it would be:

<input type="file" accept=".gif,.jpg,.jpeg,.png,.doc,.docx">

Works with all browsers, except IE9. I haven't tested it in IE10+.

Short explanation:

If an algorithm is of T(g(n)), it means that the running time of the algorithm as n (input size) gets larger is proportional to g(n).

If an algorithm is of O(g(n)), it means that the running time of the algorithm as n gets larger is at most proportional to g(n).

Normally, even when people talk about O(g(n)) they actually mean T(g(n)) but technically, there is a difference.

More technically:

O(n) represents upper bound. T(n) means tight bound. O(n) represents lower bound.

f(x) = T(g(x)) iff f(x) = O(g(x)) and f(x) = O(g(x))

Basically when we say an algorithm is of O(n), it's also O(n²), O(n^1000000), O(2ⁿ), ... but a T(n) algorithm is not T(n²).

In fact, since f(n) = T(g(n)) means for sufficiently large values of n, f(n) can be bound within c₁g(n) and c₂g(n) for some values of c₁ and c₂, i.e. the growth rate of f is asymptotically equal to g: g can be a lower bound and and an upper bound of f. This directly implies f can be a lower bound and an upper bound of g as well. Consequently,

f(x) = T(g(x)) iff g(x) = T(f(x))

Similarly, to show f(n) = T(g(n)), it's enough to show g is an upper bound of f (i.e. f(n) = O(g(n))) and f is a lower bound of g (i.e. f(n) = O(g(n)) which is the exact same thing as g(n) = O(f(n))). Concisely,

f(x) = T(g(x)) iff f(x) = O(g(x)) and g(x) = O(f(x))

There are also little-oh and little-omega (?) notations representing loose upper and loose lower bounds of a function.

To summarize:

f(x) = O(g(x)) (big-oh) means that the growth rate of f(x) is asymptotically less than or equal to to the growth rate of g(x).

f(x) = O(g(x)) (big-omega) means that the growth rate of f(x) is asymptotically greater than or equal to the growth rate of g(x)

f(x) = o(g(x)) (little-oh) means that the growth rate of f(x) is asymptotically less than the growth rate of g(x).

f(x) = ?(g(x)) (little-omega) means that the growth rate of f(x) is asymptotically greater than the growth rate of g(x)

f(x) = T(g(x)) (theta) means that the growth rate of f(x) is asymptotically equal to the growth rate of g(x)

For a more detailed discussion, you can read the definition on Wikipedia or consult a classic textbook like Introduction to Algorithms by Cormen et al.

You're currently trying to remove the exact string [] - two square brackets with nothing between them. Instead, you want to remove all [ and separately remove all ].

Personally I would avoid using replaceAll here as it introduces more confusion due to the regex part - I'd use:

String replaced = original.replace("[", "").replace("]", "");

Only use the methods which take regular expressions if you really want to do full pattern matching. When you just want to replace all occurrences of a fixed string, replace is simpler to read and understand.

(There are alternative approaches which use the regular expression form and really match patterns, but I think the above code is significantly simpler.)

Composition (If you remove "whole", “part” is also removed automatically– “Ownership”)

• Create objects of your existing class inside the new class. This is called composition because the new class is composed of objects of existing classes.

• Typically use normal member variables.

• Can use pointer values if the composition class automatically handles allocation/deallocation responsible for creation/destruction of subclasses.

Composition in C++

Aggregation (If you remove "whole", “Part” can exist – “ No Ownership”)

• An aggregation is a specific type of composition where no ownership between the complex object and the subobjects is implied. When an aggregate is destroyed, the subobjects are not destroyed.

• Typically use pointer variables/reference variable that point to an object that lives outside the scope of the aggregate class

• Can use reference values that point to an object that lives outside the scope of the aggregate class

• Not responsible for creating/destroying subclasses

An easy fix to this question is to add '[' in the start of your json file, and ending it with a ']'. This solved it for me.

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

For Xcode 8.3.2

i have resolved same issue

"This action could not be completed. Try Again (-22421)"

using following steps...

1. Quit your xcode (if open)
2. in Application Folder, Xcode 8.3.2 -->Show Package Contents -->Contents -->Application -->Application Loader (Show package contents) -->Contents -->itms -->bin -->iTMSTransporter (right click and Open with Terminal, it will auto start updating...) after updating open your project, rebuild your archive and upload it again..

For Xcode 9

issue

”This action could not be completed. Try Again (-22421)”

has been Resolved in Xcode 9. Now, we can upload app through Xcode Organizer also.

  Do your thing...

By the way, this came directly from SQL Server Studio, so if you have access to this tool, I recommend you start playing with the various "Script xxxx AS" functions that are available. Will make your life easier! :)

Say the 1st date is in A1 cell & the 2nd date is in B1 cell

Make sure that the cell type of both A1 & B1 is DATE.
Then simply put the following formula in C1:

=A1-B1

The result of this formula may look funny to you. Then Change the Cell type of C1 to GENERAL.

It will give you the difference in Days.

You can also use this formula to get the remaining days of year or change the formula as you need:

=365-(A1-B1)

$(document).ready(); is the same as any other function. it fires once the document is ready - ie loaded. the question is about what happens when multiple $(document).ready()'s are fired not when you fire the same function within multiple $(document).ready()'s

//this
<div id="target"></div>

$(document).ready(function(){
   jQuery('#target').append('target edit 1<br>');
});
$(document).ready(function(){
   jQuery('#target').append('target edit 2<br>');
});
$(document).ready(function(){
   jQuery('#target').append('target edit 3<br>');
});

//is the same as
<div id="target"></div>

$(document).ready(function(){

    jQuery('#target').append('target edit 1<br>');

    jQuery('#target').append('target edit 2<br>');

    jQuery('#target').append('target edit 3<br>');

});

both will behave exactly the same. the only difference is that although the former will achieve the same results. the latter will run a fraction of a second faster and requires less typing. :)

in conclusion where ever possible only use 1 $(document).ready();

//old answer

They will both get called in order. Best practice would be to combine them. but dont worry if its not possible. the page will not explode.

Constructor overloading is like method overloading. Constructors can be overloaded to create objects in different ways.

The compiler differentiates constructors based on how many arguments are present in the constructor and other parameters like the order in which the arguments are passed.

MongoDB version 3.6 now includes change streams which is essentially an API on top of the OpLog allowing for trigger/notification-like use cases.

Here is a link to a Java example: http://mongodb.github.io/mongo-java-driver/3.6/driver/tutorials/change-streams/

A NodeJS example might look something like:

 var MongoClient = require('mongodb').MongoClient;
    MongoClient.connect("mongodb://localhost:22000/MyStore?readConcern=majority")
     .then(function(client){
       let db = client.db('MyStore')

       let change_streams = db.collection('products').watch()
          change_streams.on('change', function(change){
            console.log(JSON.stringify(change));
          });
      });

I believe using --no-index is what you're looking for:

git diff [<options>] --no-index [--] <path> <path>

as mentioned in the git manual:

This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a working tree controlled by Git and at least one of the paths points outside the working tree, or when running the command outside a working tree controlled by Git.

From https://idlebox.net/2010/apidocs/gdb-7.0.zip/gdb_9.html

The values of arguments that were not saved in their stack frames are shown as `value optimized out'.

Im guessing you compiled with -O(somevalue) and are accessing variables a,b,c in a function where optimization has occurred.

TRUNCATE `log_url_info`;
TRUNCATE `log_visitor_info`;
TRUNCATE `index_event`;
TRUNCATE `log_visitor`;
TRUNCATE `log_url`;
TRUNCATE `report_event`;
TRUNCATE `dataflow_batch_import`;
TRUNCATE `dataflow_batch_export`;

I just use it.

An alternative and perhaps more transparent way of evaluating an empty environment variable is to use...

  if [ "x$ENV_VARIABLE" != "x" ] ; then
      echo 'ENV_VARIABLE contains something'
  fi

if the link element is:

<a id="misc" href="#misc">Miscellaneous</a>

and the Miscellaneous category is bounded by something like:

<p id="miscCategory" name="misc">....</p>

you can use jQuery to do the desired effect:

<script type="text/javascript">
  $("#misc").click(function() {
    $("#miscCategory").animate({scrollTop: $("#miscCategory").offset().top});
  });
</script>

as far as I remember it correctly.. (though, I haven't tested it and wrote it from memory)

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

If you don't want a "library" for that, you can use this badly hack:

((ViewGroup)((ViewGroup)getDialog().getWindow().getDecorView()).getChildAt(0)) //ie LinearLayout containing all the dialog (title, titleDivider, content)
.getChildAt(1) // ie the view titleDivider
.setBackgroundColor(getResources().getColor(R.color.yourBeautifulColor));

This was tested and work on 4.x; not tested under, but if my memory is good it should work for 2.x and 3.x

PROBLEM

• PHP function simplexml_load_file is throwing parsing error parser error : xmlParseEntityRef while trying to load the XML file from a URL.

CAUSE

• XML returned by the URL is not a valid XML. It contains & value instead of &. It is quite possible that there are other errors which aren't obvious at this point of time.

THINGS OUT OF OUR CONTROL

• Ideally, we should make sure that a valid XML is feed into PHP simplexml_load_file function, but it looks like we don't have any control over how the XML is created.
• It is also not possible to force simplexml_load_file to process an invalid XML file. It does not leave us with many options, other than fixing the XML file itself.

POSSIBLE SOLUTION

Convert Invalid XML to Valid XML. It can be done using PHP tidy extension. Further instructions can be found from http://php.net/manual/en/book.tidy.php

Once you are sure that the extension exists or is installed, please do the following.

/**
 * As per the question asked, the URL is loaded into a variable first, 
 * which we can assume to be $xml
 */
$xml = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<project orderno="6" campaign_name="International Relief & Development for under developed nations">

CAUTION

The developer should try to compare the invalid XML with a valid XML (generated by tidy), to see there are no adverse side effects after using tidy. Tidy does an extremely good job of doing it correctly, but it never hurts to see it visually and to be 100% sure. In our case it should be as simple as comparing $xml with $tidy.

You could use: cordova plugins list | awk '{print $1}' | xargs cordova plugins rm

and use cordova plugins list to verify if plugins are all removed.

Esc to make sure you exit insert mode, then :wq (colon w q) or ZZ (shift-Z shift-Z).

This will solve all gulp problem

sudo npm install gulp && sudo npm install --save del && sudo gulp build

my solution is this:

configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-v4:27.1.0'
    }
}

If you happen to use glibmm you can try Glib::file_get_contents.

#include <iostream>
#include <glibmm.h>

int main() {
    auto filename = "my-file.txt";
    try {
        std::string contents = Glib::file_get_contents(filename);
        std::cout << "File data:\n" << contents << std::endl;
    catch (const Glib::FileError& e) {
        std::cout << "Oops, an error occurred:\n" << e.what() << std::endl;
    }

    return 0;
}

Accepted answer is certainly a good solution, but here is the way I went about generating a CSV and serving it from a view.

Thought it was worth while putting this here as it took me a little bit of fiddling to get all the desirable behaviour (overwrite existing file, storing to the right spot, not creating duplicate files etc).

Django 1.4.1

Python 2.7.3

#Model
class MonthEnd(models.Model):
    report = models.FileField(db_index=True, upload_to='not_used')

import csv
from os.path import join

#build and store the file
def write_csv():
    path = join(settings.MEDIA_ROOT, 'files', 'month_end', 'report.csv')
    f = open(path, "w+b")

    #wipe the existing content
    f.truncate()

    csv_writer = csv.writer(f)
    csv_writer.writerow(('col1'))

    for num in range(3):
        csv_writer.writerow((num, ))

    month_end_file = MonthEnd()
    month_end_file.report.name = path
    month_end_file.save()

from my_app.models import MonthEnd

#serve it up as a download
def get_report(request):
    month_end = MonthEnd.objects.get(file_criteria=criteria)

    response = HttpResponse(month_end.report, content_type='text/plain')
    response['Content-Disposition'] = 'attachment; filename=report.csv'

    return response

For that you need to install binary of GNU GCC compiler, which comes with MinGW package. You can download MinGW( and put it under C:/ ) and later you have to download gnu -c, c++ related Binaries, so select required package and install them(in the MinGW ). Then in the Code::Blocks, go to Setting, Compiler, ToolChain Executable. In that you will find Path, there set C:/MinGW. Then mentioned error will be vanished.

I am using visual studio 2010 to make a program on SMSC Server. What you have to do is go to build-->publish. you will be asked be asked to few simple things and the location where you want to store your application, browse the location where you want to put it.

I hope this is what you are looking for

I spent a lot of time looking for a solution to this problem too. Here's what i've found thus far:

If you want your users to be able to click on a button and copy some text, you may have to use Flash.

If you want your users to press Ctrl+C anywhere on the page, but always copy xyz to the clipboard, I wrote an all-JS solution in YUI3 (although it could easily be ported to other frameworks, or raw JS if you're feeling particularly self-loathing).

It involves creating a textbox off the screen which gets highlighted as soon as the user hits Ctrl/CMD. When they hit 'C' shortly after, they copy the hidden text. If they hit 'V', they get redirected to a container (of your choice) before the paste event fires.

This method can work well, because while you listen for the Ctrl/CMD keydown anywhere in the body, the 'A', 'C' or 'V' keydown listeners only attach to the hidden text box (and not the whole body). It also doesn't have to break the users expectations - you only get redirected to the hidden box if you had nothing selected to copy anyway!

Here's what i've got working on my site, but check http://at.cg/js/clipboard.js for updates if there are any:

YUI.add('clipboard', function(Y) {


// Change this to the id of the text area you would like to always paste in to:

pasteBox = Y.one('#pasteDIV');


// Make a hidden textbox somewhere off the page.

Y.one('body').append('<input id="copyBox" type="text" name="result" style="position:fixed; top:-20%;" onkeyup="pasteBox.focus()">');
copyBox = Y.one('#copyBox');


// Key bindings for Ctrl+A, Ctrl+C, Ctrl+V, etc:

// Catch Ctrl/Window/Apple keydown anywhere on the page.
Y.on('key', function(e) {
    copyData();
        //  Uncomment below alert and remove keyCodes after 'down:' to figure out keyCodes for other buttons.
        //  alert(e.keyCode);
        //  }, 'body',  'down:', Y);
}, 'body',  'down:91,224,17', Y);

// Catch V - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
    // Oh no! The user wants to paste, but their about to paste into the hidden #copyBox!!
    // Luckily, pastes happen on keyPress (which is why if you hold down the V you get lots of pastes), and we caught the V on keyDown (before keyPress).
    // Thus, if we're quick, we can redirect the user to the right box and they can unload their paste into the appropriate container. phew.
    pasteBox.select();
}, '#copyBox',  'down:86', Y);

// Catch A - BUT ONLY WHEN PRESSED IN THE copyBox!!!
Y.on('key', function(e) {
    // User wants to select all - but he/she is in the hidden #copyBox! That wont do.. select the pasteBox instead (which is probably where they wanted to be).
    pasteBox.select();
}, '#copyBox',  'down:65', Y);



// What to do when keybindings are fired:

// User has pressed Ctrl/Meta, and is probably about to press A,C or V. If they've got nothing selected, or have selected what you want them to copy, redirect to the hidden copyBox!
function copyData() {
    var txt = '';
    // props to Sabarinathan Arthanari for sharing with the world how to get the selected text on a page, cheers mate!
        if (window.getSelection) { txt = window.getSelection(); }
        else if (document.getSelection) { txt = document.getSelection(); }
        else if (document.selection) { txt = document.selection.createRange().text; }
        else alert('Something went wrong and I have no idea why - please contact me with your browser type (Firefox, Safari, etc) and what you tried to copy and I will fix this immediately!');

    // If the user has nothing selected after pressing Ctrl/Meta, they might want to copy what you want them to copy. 
        if(txt=='') {
                copyBox.select();
        }
    // They also might have manually selected what you wanted them to copy! How unnecessary! Maybe now is the time to tell them how silly they are..?!
        else if (txt == copyBox.get('value')) {
        alert('This site uses advanced copy/paste technology, possibly from the future.\n \nYou do not need to select things manually - just press Ctrl+C! \n \n(Ctrl+V will always paste to the main box too.)');
                copyBox.select();
        } else {
                // They also might have selected something completely different! If so, let them. It's only fair.
        }
}
});

Hope someone else finds this useful :]

(Make sure to install react-router using npm!)

To use react-router, you do the following:

1. Create a file with routes defined using Route, IndexRoute components

2. Inject the Router (with 'r'!) component as the top-level component for your app, passing the routes defined in the routes file and a type of history (hashHistory, browserHistory)

3. Add {this.props.children} to make sure new pages will be rendered there
4. Use the Link component to change pages

Step 1 routes.js

import React from 'react';
import { Route, IndexRoute } from 'react-router';

/**
 * Import all page components here
 */
import App from './components/App';
import MainPage from './components/MainPage';
import SomePage from './components/SomePage';
import SomeOtherPage from './components/SomeOtherPage';

/**
 * All routes go here.
 * Don't forget to import the components above after adding new route.
 */
export default (
  <Route path="/" component={App}>
    <IndexRoute component={MainPage} />
    <Route path="/some/where" component={SomePage} />
    <Route path="/some/otherpage" component={SomeOtherPage} />
  </Route>
);

Step 2 entry point (where you do your DOM injection)

// You can choose your kind of history here (e.g. browserHistory)
import { Router, hashHistory as history } from 'react-router';
// Your routes.js file
import routes from './routes';

ReactDOM.render(
  <Router routes={routes} history={history} />,
  document.getElementById('your-app')
);

Step 3 The App component (props.children)

In the render for your App component, add {this.props.children}:

render() {
  return (
    <div>
      <header>
        This is my website!
      </header>

      <main>
        {this.props.children}
      </main>

      <footer>
        Your copyright message
      </footer>
    </div>
  );
}

Step 4 Use Link for navigation

Anywhere in your component render function's return JSX value, use the Link component:

import { Link } from 'react-router';
(...)
<Link to="/some/where">Click me</Link>

The error is due to that you're only allowed to use pipeline steps inside the steps directive. One workaround that I know is to use the script step and wrap arbitrary pipeline script inside of it and save the result in the environment variable so that it can be used later.

So in your case:

pipeline {
    agent any
    stages {
        stage("foo") {
            steps {
                script {
                    env.FILENAME = readFile 'output.txt'
                }
                echo "${env.FILENAME}"
            }
        }
    }
}

No. It makes no sense to order the records before grouping, since grouping is going to mutate the result set. The subquery way is the preferred way. If this is going too slow you would have to change your table design, for example by storing the id of of the last post for each author in a seperate table, or introduce a boolean column indicating for each author which of his post is the last one.

I also had to come up with an alternate solution, as none of the options listed here worked in my case. I was using an IEnumerable and the underlying data was a IEnumerable and the properties couldn't be enumerated. This did the trick:

// remove "this" if not on C# 3.0 / .NET 3.5
public static DataTable ConvertToDataTable<T>(this IEnumerable<T> data)
{
    List<IDataRecord> list = data.Cast<IDataRecord>().ToList();

    PropertyDescriptorCollection props = null;
    DataTable table = new DataTable();
    if (list != null && list.Count > 0)
    {
        props = TypeDescriptor.GetProperties(list[0]);
        for (int i = 0; i < props.Count; i++)
        {
            PropertyDescriptor prop = props[i];
            table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);
        }
    }
    if (props != null)
    {
        object[] values = new object[props.Count];
        foreach (T item in data)
        {
            for (int i = 0; i < values.Length; i++)
            {
                values[i] = props[i].GetValue(item) ?? DBNull.Value;
            }
            table.Rows.Add(values);
        }
    }
    return table;
}

You can loop on the chars of string and check using the Char Method IsLetter but you can also do a trick using String method IndexOfAny to search other charaters that are not suppose to be in the string.

You have to be sure to use UIPickerViewDataSource and UIPickerViewDelegate protocols or it will throw an AppDelegate error as of swift 3

Also please take note of the change in syntax:

func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int

is now:

public func numberOfComponents(in pickerView: UIPickerView) -> Int

The following below worked for me.

import UIkit

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {

    @IBOutlet weak var textBox: UITextField!
    @IBOutlet weak var dropDown: UIPickerView!

    var list = ["1", "2", "3"]

    public func numberOfComponents(in pickerView: UIPickerView) -> Int{
        return 1
    }

    public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{

        return list.count
    }

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

        self.view.endEditing(true)
        return list[row]
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

        self.textBox.text = self.list[row]
        self.dropDown.isHidden = true
    }

    func textFieldDidBeginEditing(_ textField: UITextField) {

        if textField == self.textBox {
            self.dropDown.isHidden = false
            //if you don't want the users to se the keyboard type:

            textField.endEditing(true)
        }
    }
}

To do this in Windows CLI environment, the best way I can find is to use the mode command and parse the output.

function getTerminalSizeOnWindows() {
  $output = array();
  $size = array('width'=>0,'height'=>0);
  exec('mode',$output);
  foreach($output as $line) {
    $matches = array();
    $w = preg_match('/^\s*columns\:?\s*(\d+)\s*$/i',$line,$matches);
    if($w) {
      $size['width'] = intval($matches[1]);
    } else {
      $h = preg_match('/^\s*lines\:?\s*(\d+)\s*$/i',$line,$matches);
      if($h) {
        $size['height'] = intval($matches[1]);
      }
    }
    if($size['width'] AND $size['height']) {
      break;
    }
  }
  return $size;
}

I hope it's useful!

NOTE: The height returned is the number of lines in the buffer, it is not the number of lines that are visible within the window. Any better options out there?

QFile file("bigimage.jpg");

if (file.open(QIODevice::ReadOnly))
{
    QByteArray fileData = file.readAll();

    QByteArray hashData = QCryptographicHash::hash(fileData,QCryptographicHash::Md5); // or QCryptographicHash::Sha1
    qDebug() << hashData.toHex();  // 0e0c2180dfd784dd84423b00af86e2fc

}

Please try this

for static values--onclick="return ReAssign('valuationId','user')"
for dynamic values--onclick="return ReAssign(valuationId,user)"

If you are using SELinux, check this out.

I had the same problem. I was running CentOS 8 with SELinux enforcing, and I was getting the error mentioned in the question (mysqli_real_connect(): (HY000/2002): No such file or directory) despite having all the configurations fixed correctly. I later got out of trouble after allowing MySQL connections through SELinux.

Check SELinux status using this command:

sestatus

Allow Apache to connect database through SELinux

setsebool httpd_can_network_connect_db 1

Use -P option makes the change permanent. Without this option, the boolean would be reset to 0 at reboot.

In recent versions of dmesg, you can just call dmesg -T.

Map :

1. It processes one row at a time , very similar to map() method of MapReduce.
2. You return from the transformation after every row.

MapPartitions

1. It processes the complete partition in one go.
2. You can return from the function only once after processing the whole partition.
3. All intermediate results needs to be held in memory till you process the whole partition.
4. Provides you like setup() map() and cleanup() function of MapReduce

For JavaScript arrays, you use Both push() and concat() function.

var array = [1, 2, 3];
array.push(4, 5);         //use push for appending a single array.




var array1 = [1, 2, 3];
var array2 = [4, 5, 6];

var array3 = array1.concat(array2);   //It is better use concat for appending more then one array.

use checked : true, false property of the checkbox.

The easiest would probably be tag stripping combined with replacement of some tags with text layout elements like dashes for list elements (li) and line breaks for br's and p's. It shouldn't be too hard to extend this to tables.

this works well for me

    arglen=$#
    argparam=$*
    if [ $arglen -eq '3' ];
    then
            echo Valid Number of arguments
            echo "Arguments are $*"
    else
            echo only four arguments are allowed
    fi

Not for this Problem, but here's some code to compare lists for equal and not! identical objects:

public class EquatableList<T> : List<T>, IEquatable<EquatableList<T>> where    T : IEquatable<T>

/// <summary>
/// True, if this contains element with equal property-values
/// </summary>
/// <param name="element">element of Type T</param>
/// <returns>True, if this contains element</returns>
public new Boolean Contains(T element)
{
    return this.Any(t => t.Equals(element));
}

/// <summary>
/// True, if list is equal to this
/// </summary>
/// <param name="list">list</param>
/// <returns>True, if instance equals list</returns>
public Boolean Equals(EquatableList<T> list)
{
    if (list == null) return false;
    return this.All(list.Contains) && list.All(this.Contains);
}

There are already good, detailed answers here, but no visual examples, so here's a quick illustration:

<div>This is a div.</div>_x000D_
<div>This is a div.</div>_x000D_
<div>This is a div.</div>_x000D_
<span>This is a span.</span>_x000D_
<span>This is a span.</span>_x000D_
<span>This is a span.</span>

<div> is a block tag, while <span> is an inline tag.

Why the base class' default constructor is called? Turns out it's not always be the case. Any constructor of the base class (with different signatures) can be invoked from the derived class' constructor. In your case, the default constructor is called because it has no parameters so it's default.

When a derived class is created, the order the constructors are called is always Base -> Derived in the hierarchy. If we have:

class A {..}
class B : A {...}
class C : B {...}
C c;

When c is create, the constructor for A is invoked first, and then the constructor for B, and then the constructor for C.

To guarantee that order, when a derived class' constructor is called, it always invokes the base class' constructor before the derived class' constructor can do anything else. For that reason, the programmer can manually invoke a base class' constructor in the only initialisation list of the derived class' constructor, with corresponding parameters. For instance, in the following code, Derived's default constructor will invoke Base's constructor Base::Base(int i) instead of the default constructor.

Derived() : Base(5)
{      
}

If there's no such constructor invoked in the initialisation list of the derived class' constructor, then the program assumes a base class' constructor with no parameters. That's the reason why a constructor with no parameters (i.e. the default constructor) is invoked.

Try this:

 window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat="+elemA+"&lon="+elemB+"&setLatLon=Set";

To put a variable in a string enclose the variable in quotes and addition signs like this:

var myname = "BOB";
var mystring = "Hi there "+myname+"!"; 

Just remember that one rule!

It's even easier in Windows 8.1 and Server 2012 R2.

Do this once: Right-click on the task bar, choose Properties. In the Navigation tab, turn on [✓] Replace Command Prompt with Windows PowerShell in the menu when I right-click the lower-left corner or press Windows key+X.

Then whenever you want a PowerShell prompt, hit Win+X, I. (Or Win+X, A for an Admin PowerShell prompt)

You need also $sce.trustAsResourceUrl or it won't open the website inside the iframe:

angular.module('myApp', [])_x000D_
    .controller('dummy', ['$scope', '$sce', function ($scope, $sce) {_x000D_
_x000D_
    $scope.url = $sce.trustAsResourceUrl('https://www.angularjs.org');_x000D_
_x000D_
    $scope.changeIt = function () {_x000D_
        $scope.url = $sce.trustAsResourceUrl('https://docs.angularjs.org/tutorial');_x000D_
    }_x000D_
}]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>_x000D_
_x000D_
<div ng-app="myApp" ng-controller="dummy">_x000D_
    <iframe ng-src="{{url}}" width="300" height="200"></iframe>_x000D_
    <br>_x000D_
    <button ng-click="changeIt()">Change it</button>_x000D_
</div>

In your test code your are trying to pass App to the spyOn function, but spyOn will only work with objects, not classes. Generally you need to use one of two approaches here:

1) Where the click handler calls a function passed as a prop, e.g.

class App extends Component {

  myClickFunc = () => {
      console.log('clickity clickcty');
      this.props.someCallback();
  }
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro" onClick={this.myClickFunc}>
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

You can now pass in a spy function as a prop to the component, and assert that it is called:

describe('my sweet test', () => {
 it('clicks it', () => {
    const spy = jest.fn();
    const app = shallow(<App someCallback={spy} />)
    const p = app.find('.App-intro')
    p.simulate('click')
    expect(spy).toHaveBeenCalled()
 })
})

2) Where the click handler sets some state on the component, e.g.

class App extends Component {
  state = {
      aProperty: 'first'
  }

  myClickFunc = () => {
      console.log('clickity clickcty');
      this.setState({
          aProperty: 'second'
      });
  }
  render() {
    return (
      <div className="App">
        <div className="App-header">
          <img src={logo} className="App-logo" alt="logo" />
          <h2>Welcome to React</h2>
        </div>
        <p className="App-intro" onClick={this.myClickFunc}>
          To get started, edit <code>src/App.js</code> and save to reload.
        </p>
      </div>
    );
  }
}

You can now make assertions about the state of the component, i.e.

describe('my sweet test', () => {
 it('clicks it', () => {
    const app = shallow(<App />)
    const p = app.find('.App-intro')
    p.simulate('click')
    expect(app.state('aProperty')).toEqual('second');
 })
})

Sounds like an ideal application for RegEx -- an engine designed for fast text manipulation. In this case:

Regex.Replace("He\"ll,o Wo'r.ld", "[@,\\.\";'\\\\]", string.Empty)

 var testArray= ['a','b','c','d','e','b','c','d'];

 function removeDuplicatesFromArray(arr){

 var obj={};
 var uniqueArr=[];
 for(var i=0;i<arr.length;i++){ 
    if(!obj.hasOwnProperty(arr[i])){
        obj[arr[i]] = arr[i];
        uniqueArr.push(arr[i]);
    }
 }

return uniqueArr;

}
var newArr = removeDuplicatesFromArray(testArray);
console.log(newArr);

Output:- [ 'a', 'b', 'c', 'd', 'e' ]

because u have to have jquery set-up to enable the toggling functionality of the toggler button. So, all u have to do is to add bootstrap.bundle.js before bootstrap.css:

<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>

This answer is for those seeking to just change the value of a data-attribute

The suggested will not change the value of your Jquery data-attr correctly as @adeneo has stated. For some reason though, I'm not seeing him (or any others) post the correct method for those seeking to update their data-attr. The answer that @Lucas Willems has posted may be the answer to problem Brian Tompsett - ??? is having, but it's not the answer to the inquiry that may be bringing other users here.

Quick answer in regards to original inquiry statement

-To update data-attr

$('#ElementId').attr('data-attributeTitle',newAttributeValue);

Easy mistakes* - there must be "data-" at the beginning of your attribute you're looking to change the value of.

If you do not mind the items being imutable you can use the Tuple class added to .net 4

var list = new List<Tuple<string,int>>();
list.Add(new Tuple<string,int>("hello", 1));

list[0].Item1 //Hello
list[0].Item2 //1

However if you are adding two items every time and one of them is unique id you can use a Dictionary

There is no option to set a min or max value in seekbar , so you can use a formula here to scale your value.

Desired_value = ( progress * ( Max_value - Min_value) / 100 ) + Min_value

I have tested this formula in many examples. In your example, if the progressBar is the middle(i.e. progress = 50 ) and your Min_val and Max_val are 60 and 180 respectively, then this formula will give you the Desired_value '120'.

You haven't provided your javascript code, but the usual cause of this type of issue is not waiting till the page is loaded. Remember that most javascript is executed before the DOM is loaded, so code trying to manipulate it won't work.

To run code after the page has finished loading, use the $(document).ready callback:

$(document).ready(function(){
  $('#some-id').trigger('click');
});

By default, a grid item cannot be smaller than the size of its content.

Grid items have an initial size of min-width: auto and min-height: auto.

You can override this behavior by setting grid items to min-width: 0, min-height: 0 or overflow with any value other than visible.

From the spec:

6.6. Automatic Minimum Size of Grid Items

To provide a more reasonable default minimum size for grid items, this specification defines that the auto value of min-width / min-height also applies an automatic minimum size in the specified axis to grid items whose overflow is visible. (The effect is analogous to the automatic minimum size imposed on flex items.)

Here's a more detailed explanation covering flex items, but it applies to grid items, as well:

• Why don't flex items shrink past content size?

This post also covers potential problems with nested containers and known rendering differences among major browsers.

To fix your layout, make these adjustments to your code:

.month-grid {
  display: grid;
  grid-template: repeat(6, 1fr) / repeat(7, 1fr);
  background: #fff;
  grid-gap: 2px;
  min-height: 0;  /* NEW */
  min-width: 0;   /* NEW; needed for Firefox */
}

.day-item {
  padding: 10px;
  background: #DFE7E7;
  overflow: hidden;  /* NEW */
  min-width: 0;      /* NEW; needed for Firefox */
}

jsFiddle demo

1fr vs minmax(0, 1fr)

The solution above operates at the grid item level. For a container level solution, see this post:

• Who does minmax(0, 1fr) work for long elements while 1fr doesn't?

If the Subversion server version is not printed in the HTML listing, it is available in the HTTP RESPONSE header returned by the server. You can get it using this shell command

wget -S --no-check-certificate \
  --spider 'http://svn.server.net/svn/repository' 2>&1 \
  | sed -n '/SVN/s/.*\(SVN[0-9\/\.]*\).*/\1/p';

If the SVN server requires you provide a user name and password, then add the wget parameters --user and --password to the command like this

wget -S --no-check-certificate \
  --user='username' --password='password' \
  --spider 'http://svn.server.net/svn/repository' 2>&1 \
  | sed -n '/SVN/s/.*\(SVN[0-9\/\.]*\).*/\1/p';

It seems pretty consistent to me; positive indices are also non-inclusive. I think you're doing it wrong. Remembering that range() is also non-inclusive, and that Python arrays are 0-indexed, here's a sample python session to illustrate:

>>> d = range(10)
>>> d
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> d[9]
9
>>> d[-1]
9
>>> d[0:9]
[0, 1, 2, 3, 4, 5, 6, 7, 8]
>>> d[0:-1]
[0, 1, 2, 3, 4, 5, 6, 7, 8]
>>> len(d)
10

Some great examples (and a ready-made JavaScript SOAP client!) here: http://plugins.jquery.com/soap/

Check the readme, and beware the same-origin browser restriction.

All below options worked for me.

Option 1: Annotation for FIELD at class & field level with getter/setter methods

 @XmlRootElement(name = "fields")
 @XmlAccessorType(XmlAccessType.FIELD)
    public class Fields {

        @XmlElement(name = "field")
        List<Field> fields = new ArrayList<Field>();
            //getter, setter
    }

Option 2: No Annotation for FIELD at class level(@XmlAccessorType(XmlAccessType.FIELD) and with only getter method. Adding Setter method will throw the error as we are not including the Annotation in this case. Remember, setter is not required when you explicitly set the values in your XML file.

@XmlRootElement(name = "fields")
    public class Fields {

        @XmlElement(name = "field")
        List<Field> fields = new ArrayList<Field>();
            //getter
    }

Option 3: Annotation at getter method alone. Remember we can also use the setter method here as we are not doing any FIELD level annotation in this case.

@XmlRootElement(name = "fields")
    public class Fields {

        List<Field> fields = new ArrayList<Field>();

        @XmlElement(name = "field")
        //getter

        //setter
    }

Hope this helps you!

If you're not using the less version, here is the line you need to change:

@media (max-width: 767px) { /* Change this to 0 */
  .navbar-nav .open .dropdown-menu {
    position: static;
    float: none;
    width: auto;
    margin-top: 0;
    background-color: transparent;
    border: 0;
    box-shadow: none;
  }
  .navbar-nav .open .dropdown-menu > li > a,
  .navbar-nav .open .dropdown-menu .dropdown-header {
    padding: 5px 15px 5px 25px;
  }
  .navbar-nav .open .dropdown-menu > li > a {
    line-height: 20px;
  }
  .navbar-nav .open .dropdown-menu > li > a:hover,
  .navbar-nav .open .dropdown-menu > li > a:focus {
    background-image: none;
  }
}

There are multiple horizontal centering methods in Bootstrap 4...

• text-center for center display:inline elements
• offset-* or mx-auto can be used to center column (col-*)
• or, justify-content-center on the row to center columns (col-*)
• mx-auto for centering display:block elements inside d-flex

mx-auto (auto x-axis margins) will center display:block or display:flex elements that have a defined width, (%, vw, px, etc..). Flexbox is used by default on grid columns, so there are also various flexbox centering methods.

Demo of the Bootstrap 4 Centering Methods

In your case, use mx-auto to center the col-3 and text-center to center it's content..

<div class="row">
    <div class="col-3 mx-auto">
        <div class="text-center">
            center
        </div>
    </div>
</div>

https://codeply.com/go/GRUfnxl3Ol

or, using justify-content-center on flexbox elements (.row):

<div class="container">
    <div class="row justify-content-center">
        <div class="col-3 text-center">
            center
        </div>
    </div>
</div>

We tried several things before arriving at an acceptable solution:

xxd -u /usr/bin/xxd | grep 'DF'
00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....


root# grep -ibH "df" /usr/bin/xxd
Binary file /usr/bin/xxd matches
xxd -u /usr/bin/xxd | grep -H 'DF'
(standard input):00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....

Then found we could get usable results with

xxd -u /usr/bin/xxd > /tmp/xxd.hex ; grep -H 'DF' /tmp/xxd

Note that using a simple search target like 'DF' will incorrectly match characters that span across byte boundaries, i.e.

xxd -u /usr/bin/xxd | grep 'DF'
00017b0: 4010 8D05 0DFF FF0A 0300 53E3 0610 A003  @.........S.....
--------------------^^

So we use an ORed regexp to search for ' DF' OR 'DF ' (the searchTarget preceded or followed by a space char).

The final result seems to be

xxd -u -ps -c 10000000000 DumpFile > DumpFile.hex
egrep ' DF|DF ' Dumpfile.hex

0001020: 0089 0424 8D95 D8F5 FFFF 89F0 E8DF F6FF  ...$............
-----------------------------------------^^
0001220: 0C24 E871 0B00 0083 F8FF 89C3 0F84 DF03  .$.q............

You need the actual package (the directory containing __init__.py) stored somewhere that's in your system's PYTHONPATH. Normally, packages are distributed with a directory above the package directory, containing setup.py (which you should use to install the package), documentation, etc. This directory is not a package. Additionally, your Python27 directory is probably not in PYTHONPATH; more likely one or more subdirectories of it are.

I found a solution why R.class is not made by Eclipse after making it again - 2 clean, build, etc.

The problem is here in strings.xml:

<string name="hello">Hello World, HelloAutoComplete!</string>

<string name="app_name">HelloAutoComplete</string>

These are by default created by Eclipse when you create projects.

Definitely you are changing the strings.xml for your own requirement. Sometimes you clear the string.xmls these two lines from your code:

It is making a problem in the AndroidManifest.xml file:

<application android:icon="@drawable/icon"  android:label="@string/app_name">
<activity android:name=".HelloAutoComplete" android:label="@string/app_name">

So it can't communicate with strings.xml.

With plt.scatter, I can only think of one: to use a proxy artist:

df = pd.DataFrame(np.random.normal(10,1,30).reshape(10,3), index = pd.date_range('2010-01-01', freq = 'M', periods = 10), columns = ('one', 'two', 'three'))
df['key1'] = (4,4,4,6,6,6,8,8,8,8)
fig1 = plt.figure(1)
ax1 = fig1.add_subplot(111)
x=ax1.scatter(df['one'], df['two'], marker = 'o', c = df['key1'], alpha = 0.8)

ccm=x.get_cmap()
circles=[Line2D(range(1), range(1), color='w', marker='o', markersize=10, markerfacecolor=item) for item in ccm((array([4,6,8])-4.0)/4)]
leg = plt.legend(circles, ['4','6','8'], loc = "center left", bbox_to_anchor = (1, 0.5), numpoints = 1)

And the result is:

I have a couple of suggestions:

1. First of all, you seem to be using API 4 as your target. AFAIK, it's good practice to always compile against the latest SDK and setup your android:minSdkVersion accordingly.

2. With that in mind, remember that android:required attribute was added in API 5:

The feature declaration can include an android:required=["true" | "false"] attribute (if you are compiling against API level 5 or higher), which lets you specify whether the application (...)

Thus, I'd suggest that you compile against SDK 15, set targetSdkVersion to 15 as well, and provide that functionality.

It also shows here, on the Play site, as incompatible with any device that I have that is (coincidence?) Gingerbread (Galaxy Ace and Galaxy Y here). But it shows as compatible with my Galaxy Tab 10.1 (Honeycomb), Nexus S and Galaxy Nexus (both on ICS).

That also left me wondering, and this is a very wild guess, but since android.hardware.faketouch is API11+, why don't you try removing it just to see if it works? Or perhaps that's all related anyway, since you're trying to use features (faketouch) and the required attribute that are not available in API 4. And in this case you should compile against the latest API.

I would try that first, and remove the faketouch requirement only as last resort (of course) --- since it works when developing, I'd say it's just a matter of the compiled app not recognizing the feature (due to the SDK requirements), thus leaving unexpected filtering issues on Play.

Sorry if this guess doesn't answer your question, but it's very difficult to diagnose those kind of problems and pinpoint the solution without actually testing. Or at least for me without all the proper knowledge of how Play really filters apps.

Good luck.

As dfsq said i just had to use removeClass("hide") instead of toggle()

First think of a solution without code. The idea is to print an odd number of *, increasing by line. Then center the * by using spaces. Knowing the max number of * in the last line, will give you the initial number of spaces to center the first *. Now write it in code.

Public Oracle Java 6 releases do not support TLSv1.2. Paid-for releases of Java 6 (post-EOL) might. (UPDATE - TLSv1.1 is available for Java 1.6 from update 111 onwards; source)

Contact Oracle sales.

Other alternatives are:

• Use an alternative JCE implementation such as Bouncy Castle. See this answer for details on how to do it. It changes the default SSLSocketFactory implementation, so that your application will use BC transparently. (Other answers show how to use the BC SSLSocketFactory implementation explicitly, but that approach will entail modifying application or library code that that is opening sockets.)

• Use an IBM Java 6 ... if available for your platform. According to "IBM SDK, Java Technology Edition fixes to mitigate against the POODLE security vulnerability (CVE-2014-3566)":

  "TLSv1.1 and TLSv1.2 are available only for Java 6 service refresh 10, Java 6.0.1 service refresh 1 (J9 VM2.6), and later releases."

However, I'd advise upgrading to a Java 11 (now). Java 6 was EOL'd in Feb 2013, and continuing to use it is potentially risky. Free Oracle Java 8 is EOL for many use-cases. (Tell or remind the boss / the client. They need to know.)

You didnt specify the platform you use, so I assume it's a Mac ;-)

What I do is use a proxy. I use SquidMan, a standalone implementation of Squid

I start SquidMan on the Mac, then on the iPhone I enter the Proxy params in the General/Wifi Settings.

Then I can watch the HTTP trafic in the Console App, looking at the squid-access.log

If I need more infos, I switch to tcpdump, but I suppose WireShark should work too.

It gives out a string of max 200 characters OR 200 normal characters OR 200 characters followed by '...'

$ur_str= (strlen($ur_str) > 200) ? substr($ur_str,0,200).'...' :$ur_str;

Have your tried using the 'return' keyword?

// Set NavigationBar Title Programmatically and Dynamic

Note : First add NavigationControllerItem to Your ViewController then goto their ViewController.swift file and Just Copy and Paste this in viewDidLoad().

navigationItem.title = "Your Title Here"

You can Try this also :

 public static String convertToNameCase(String s)
    {
        if (s != null)
        {
            StringBuilder b = new StringBuilder();
            String[] split = s.split(" ");
            for (String srt : split)
            {
                if (srt.length() > 0)
                {
                    b.append(srt.substring(0, 1).toUpperCase()).append(srt.substring(1).toLowerCase()).append(" ");
                }
            }
            return b.toString().trim();
        }
        return s;
    }

Reading CSV format description makes me feel that using 3rd party library would be less headache than writing it myself:

• http://en.wikipedia.org/wiki/Comma-separated_values

Wikipedia lists 10 or something known libraries:

• http://en.wikipedia.org/wiki/CSV_application_support

I compared libs listed using some kind of check list. OpenCSV turned out a winner to me (YMMV) with the following results:

+ maven

+ maven - release version   // had some cryptic issues at _Hudson_ with snapshot references => prefer to be on a safe side

+ code examples

+ open source   // as in "can hack myself if needed"

+ understandable javadoc   // as opposed to eg javadocs of _genjava gj-csv_

+ compact API   // YAGNI (note *flatpack* seems to have much richer API than OpenCSV)

- reference to specification used   // I really like it when people can explain what they're doing

- reference to _RFC 4180_ support   // would qualify as simplest form of specification to me

- releases changelog   // absence is quite a pity, given how simple it'd be to get with maven-changes-plugin   // _flatpack_, for comparison, has quite helpful changelog

+ bug tracking

+ active   // as in "can submit a bug and expect a fixed release soon"

+ positive feedback   // Recommended By 51 users at sourceforge (as of now)

Almost 5 years later, I think my answer can reduce a little bit the hard work of many people.

Update an element in the DOM with the HTML from the one from the ajax call can be achieved that way

$('#submitform').click(function() {
     $.ajax({
     url: "getinfo.asp",
     data: {
         txtsearch: $('#appendedInputButton').val()
     },
     type: "GET",
     dataType : "html",
     success: function (data){
         $('#showresults').html($('#showresults',data).html());
         // similar to $(data).find('#showresults')
     },
});

or with replaceWith()

// codes

success: function (data){
   $('#showresults').replaceWith($('#showresults',data));
},

A two line intuitive solution to round to a given time unit, here seconds, for a datetime object t:

format_str = '%Y-%m-%d %H:%M:%S'
t_rounded = datetime.strptime(datetime.strftime(t, format_str), format_str)

If you wish to round to a different unit simply alter format_str.

This approach does not round to arbitrary time amounts as above methods, but is a nicely Pythonic way to round to a given hour, minute or second.

This is definitely help. Working. but set separator "none" from attribute inspector. Write following code in cellForRowAtIndexPath method

 UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(0,           
 cell.contentView.frame.size.height - 1.0,      
 cell.contentView.frame.size.width, 1)];

    lineView.backgroundColor = [UIColor blackColor];
    [cell.contentView addSubview:lineView];

The idea ...To create a File object (api) in javaScript for images already present in the DOM :

<img src="../img/Products/fijRKjhudDjiokDhg1524164151.jpg">

var file = new File(['fijRKjhudDjiokDhg1524164151'],
                     '../img/Products/fijRKjhudDjiokDhg1524164151.jpg', 
                     {type:'image/jpg'});

// created object file
console.log(file);

Don't do that ! ... (but I did it anyway)

-> the console give a result similar as an Object File :

File(0) {name: "fijRKjokDhgfsKtG1527053050.jpg", lastModified: 1527053530715, lastModifiedDate: Wed May 23 2018 07:32:10 GMT+0200 (Paris, Madrid (heure d’été)), webkitRelativePath: "", size: 0, …}
lastModified:1527053530715
lastModifiedDate:Wed May 23 2018 07:32:10 GMT+0200 (Paris, Madrid (heure d’été)) {}
name:"fijRKjokDhgfsKtG1527053050.jpg"
size:0
type:"image/jpg"
webkitRelativePath:""__proto__:File

But the size of the object is wrong ...

Why i need to do that ?

For example to retransmit an image form already uploaded, during a product update, along with additional images added during the update

First of all I'd like to note that you cannot even rely on the fact that (-1) % 8 == -1. the only thing you can rely on is that (x / y) * y + ( x % y) == x. However whether or not the remainder is negative is implementation-defined.

Now why use templates here? An overload for ints and longs would do.

int mod (int a, int b)
{
   int ret = a % b;
   if(ret < 0)
     ret+=b;
   return ret;
}

and now you can call it like mod(-1,8) and it will appear to be 7.

Edit: I found a bug in my code. It won't work if b is negative. So I think this is better:

int mod (int a, int b)
{
   if(b < 0) //you can check for b == 0 separately and do what you want
     return -mod(-a, -b);   
   int ret = a % b;
   if(ret < 0)
     ret+=b;
   return ret;
}

Reference: C++03 paragraph 5.6 clause 4:

The binary / operator yields the quotient, and the binary % operator yields the remainder from the division of the first expression by the second. If the second operand of / or % is zero the behavior is undefined; otherwise (a/b)*b + a%b is equal to a. If both operands are nonnegative then the remainder is nonnegative; if not, the sign of the remainder is implementation-defined.

Reflection is slower, but works for a situation when you want to know whether that is of type Dog or a Cat and not an instance of Animal. So you'd do something like:

if(null != items.elementAt(1) && items.elementAt(1).getClass().toString().equals("Cat"))
{
//do whatever with cat.. not any other instance of animal.. eg. hideClaws();
}

Not saying the answer above does not work, except the null checking part is necessary.

Another way to answer that is use generics and you are guaranteed to have Double as any element of items.

List<Double> items = new ArrayList<Double>();

Lets say your HTML looks something like this:

<div class="box">
    <!-- stuff -->
    <p class="bet_time">Bet 5 days ago</p>
</div>

Then, with CSS, you can make that text appear in the bottom right like so:

.box {
    position:relative;
}
.bet_time {
    position:absolute;
    bottom:0;
    right:0;
}

The way this works is that absolutely positioned elements are always positioned with respect to the first relatively positioned parent element, or the window. Because we set the box's position to relative, .bet_time positions its right edge to the right edge of .box and its bottom edge to the bottom edge of .box

You should use System.DirectoryServices.AccountManagement. It's much easier. Here is a nice code project article giving you an overview on all the classes in this DLL.

As you pointed out, your current approach doesn't find out the primary group. Actually, it's much worse than you thought. There are some more cases that it doesn't work, like the domain local group from another domain. You can check here for details. Here is how the code looks like if you switch to use System.DirectoryServices.AccountManagement. The following code can find the immediate groups this user assigned to, which includes the primary group.

UserPrincipal user = UserPrincipal.FindByIdentity(new PrincipalContext (ContextType.Domain, "mydomain.com"), IdentityType.SamAccountName, "username");
foreach (GroupPrincipal group in user.GetGroups())
{
    Console.Out.WriteLine(group);
}

It is easy to create a self-signed certificate, import it, and bind it to your website.

1.) Create a self-signed certificate:

Run the following 4 commands, one at a time, from an elevated Command Prompt:

cd C:\Program Files (x86)\Windows Kits\8.1\bin\x64

makecert -r -n "CN=localhost" -b 01/01/2000 -e 01/01/2099 -eku 1.3.6.1.5.5.7.3.3 -sv localhost.pvk localhost.cer

cert2spc localhost.cer localhost.spc

pvk2pfx -pvk localhost.pvk -spc localhost.spc -pfx localhost.pfx

2.) Import certificate to Trusted Root Certification Authorities store:

start --> run --> mmc.exe --> Certificates plugin --> "Trusted Root Certification Authorities" --> Certificates

Right-click Certificates --> All Tasks --> Import Find your "localhost" Certificate at C:\Program Files (x86)\Windows Kits\8.1\bin\x64\

3.) Bind certificate to website:

start --> (IIS) Manager --> Click on your Server --> Click on Sites --> Click on your top level site --> Bindings

Add or edit a binding for https and select the SSL certificate called "localhost".

4.) Import Certificate to Chrome:

Chrome Settings --> Manage Certificates --> Import .pfx certificate from C:\certificates\ folder

Test Certificate by opening Chrome and navigating to https://localhost/

I just came across a similar situation and was surprised at the rounding issues of 'very large numbers' presented within SSMS v17.9.1 / SQL 2017.

I am not suggesting I have a solution, however I have observed that FORMAT presents a number which appears correct. I can not imply this reduces further rounding issues or is useful within a complicated mathematical function.

T SQL Code supplied which should clearly demonstrate my observations while enabling others to test their code and ideas should the need arise.

SQL Developer will look in the following location in this order for a tnsnames.ora file

1. $HOME/.tnsnames.ora
2. $TNS_ADMIN/tnsnames.ora
3. TNS_ADMIN lookup key in the registry
4. /etc/tnsnames.ora ( non-windows )
5. $ORACLE_HOME/network/admin/tnsnames.ora
6. LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME_KEY
7. LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME

To see which one SQL Developer is using, issue the command show tns in the worksheet

If your tnsnames.ora file is not getting recognized, use the following procedure:

1. Define an environmental variable called TNS_ADMIN to point to the folder that contains your tnsnames.ora file.

   In Windows, this is done by navigating to Control Panel > System > Advanced system settings > Environment Variables...

   In Linux, define the TNS_ADMIN variable in the .profile file in your home directory.

2. Confirm the os is recognizing this environmental variable

   From the Windows command line: echo %TNS_ADMIN%

   From linux: echo $TNS_ADMIN

3. Restart SQL Developer

4. Now in SQL Developer right click on Connections and select New Connection.... Select TNS as connection type in the drop down box. Your entries from tnsnames.ora should now display here.

I see three possibilities here that will help you insert into your table without making a complete mess but "specifying" a value for the AUTO_INCREMENT column, since you are supplying all the values you can do either one of the following options.

First approach (Supplying NULL):

INSERT INTO test.authors VALUES (
 NULL,'1','67','0','0','1','10','0','1','2012-01-03 12:50:49','108929',
 '2012-01-03 12:50:59','198963','21','',
 '/usr/local/nagios/libexec/check_ping  5','30','0','4.04159',
 '0.102','1','PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms',
 '','rta=2.860000m=0%;80;100;0'
);

Second approach (Supplying '' {Simple quotes / apostrophes} although it will give you a warning):

INSERT INTO test.authors VALUES (
 '','1','67','0','0','1','10','0','1','2012-01-03 12:50:49','108929',
 '2012-01-03 12:50:59','198963','21','',
 '/usr/local/nagios/libexec/check_ping  5','30','0','4.04159',
 '0.102','1','PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms',
 '','rta=2.860000m=0%;80;100;0'
);

Third approach (Supplying default):

INSERT INTO test.authors VALUES (
 default,'1','67','0','0','1','10','0','1','2012-01-03 12:50:49','108929',
 '2012-01-03 12:50:59','198963','21','',
 '/usr/local/nagios/libexec/check_ping  5','30','0','4.04159',
 '0.102','1','PING WARNING -DUPLICATES FOUND! Packet loss = 0%, RTA = 2.86 ms',
 '','rta=2.860000m=0%;80;100;0'
);

Either one of these examples should suffice when inserting into that table as long as you include all the values in the same order as you defined them when creating the table.

The short version: use formatC or sprintf.

The longer version:

There are several functions available for formatting numbers, including adding leading zeroes. Which one is best depends upon what other formatting you want to do.

The example from the question is quite easy since all the values have the same number of digits to begin with, so let's try a harder example of making powers of 10 width 8 too.

anim <- 25499:25504
x <- 10 ^ (0:5)

paste (and it's variant paste0) are often the first string manipulation functions that you come across. They aren't really designed for manipulating numbers, but they can be used for that. In the simple case where we always have to prepend a single zero, paste0 is the best solution.

paste0("0", anim)
## [1] "025499" "025500" "025501" "025502" "025503" "025504"

For the case where there are a variable number of digits in the numbers, you have to manually calculate how many zeroes to prepend, which is horrible enough that you should only do it out of morbid curiosity.

str_pad from stringr works similarly to paste, making it more explicit that you want to pad things.

library(stringr)
str_pad(anim, 6, pad = "0")
## [1] "025499" "025500" "025501" "025502" "025503" "025504"

Again, it isn't really designed for use with numbers, so the harder case requires a little thinking about. We ought to just be able to say "pad with zeroes to width 8", but look at this output:

str_pad(x, 8, pad = "0")
## [1] "00000001" "00000010" "00000100" "00001000" "00010000" "0001e+05"

You need to set the scientific penalty option so that numbers are always formatted using fixed notation (rather than scientific notation).

library(withr)
with_options(
  c(scipen = 999), 
  str_pad(x, 8, pad = "0")
)
## [1] "00000001" "00000010" "00000100" "00001000" "00010000" "00100000"

stri_pad in stringi works exactly like str_pad from stringr.

formatC is an interface to the C function printf. Using it requires some knowledge of the arcana of that underlying function (see link). In this case, the important points are the width argument, format being "d" for "integer", and a "0" flag for prepending zeroes.

formatC(anim, width = 6, format = "d", flag = "0")
## [1] "025499" "025500" "025501" "025502" "025503" "025504"
formatC(x, width = 8, format = "d", flag = "0")
## [1] "00000001" "00000010" "00000100" "00001000" "00010000" "00100000"

This is my favourite solution, since it is easy to tinker with changing the width, and the function is powerful enough to make other formatting changes.

sprintf is an interface to the C function of the same name; like formatC but with a different syntax.

sprintf("%06d", anim)
## [1] "025499" "025500" "025501" "025502" "025503" "025504"
sprintf("%08d", x)
## [1] "00000001" "00000010" "00000100" "00001000" "00010000" "00100000"

The main advantage of sprintf is that you can embed formatted numbers inside longer bits of text.

sprintf(
  "Animal ID %06d was a %s.", 
  anim, 
  sample(c("lion", "tiger"), length(anim), replace = TRUE)
)
## [1] "Animal ID 025499 was a tiger." "Animal ID 025500 was a tiger."
## [3] "Animal ID 025501 was a lion."  "Animal ID 025502 was a tiger."
## [5] "Animal ID 025503 was a tiger." "Animal ID 025504 was a lion." 

See also goodside's answer.

For completeness it is worth mentioning the other formatting functions that are occasionally useful, but have no method of prepending zeroes.

format, a generic function for formatting any kind of object, with a method for numbers. It works a little bit like formatC, but with yet another interface.

prettyNum is yet another formatting function, mostly for creating manual axis tick labels. It works particularly well for wide ranges of numbers.

The scales package has several functions such as percent, date_format and dollar for specialist format types.

I found an extra

  <dependentAssembly>
    <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-2.2.28.0" newVersion="2.2.28.0" />
  </dependentAssembly>

in my web.config. removed that to get it to work. some other package I installed, and then removed caused the issue.

Are you trying to remove a single value or all matching values?

If you are trying to remove a single value, how do you define the value you wish to remove?

The reason you don't get a key back when querying on values is because the dictionary could contain multiple keys paired with the specified value.

If you wish to remove all matching instances of the same value, you can do this:

foreach(var item in dic.Where(kvp => kvp.Value == value).ToList())
{
    dic.Remove(item.Key);
}

And if you wish to remove the first matching instance, you can query to find the first item and just remove that:

var item = dic.First(kvp => kvp.Value == value);

dic.Remove(item.Key);

Note: The ToList() call is necessary to copy the values to a new collection. If the call is not made, the loop will be modifying the collection it is iterating over, causing an exception to be thrown on the next attempt to iterate after the first value is removed.

Convert an iterable to a list may have a cost. Instead, to get the the first item, you can use:

next(iter(keys))

Or, if you want to iterate over all items, you can use:

items = iter(keys)
while True:
    try:
        item = next(items)
    except StopIteration as e:
        pass # finish

How about

vim -O a a

That way you can edit a single file on your left and navigate the whole dir on your right... Just a thought, not the solution...

An additional clarification is that factories can create functions/primitives, while services cannot. Check out this jsFiddle based on Epokk's: http://jsfiddle.net/skeller88/PxdSP/1351/.

The factory returns a function that can be invoked:

myApp.factory('helloWorldFromFactory', function() {
  return function() {
    return "Hello, World!";
  };
});

The factory can also return an object with a method that can be invoked:

myApp.factory('helloWorldFromFactory', function() {
  return {
    sayHello: function() {
      return "Hello, World!";
    }
  };
});

The service returns an object with a method that can be invoked:

myApp.service('helloWorldFromService', function() {
  this.sayHello = function() {
     return "Hello, World!";
  };
});

For more details, see a post I wrote on the difference: http://www.shanemkeller.com/tldr-services-vs-factories-in-angular/

The syntax is:

=GOOGLEFINANCE(ticker, [attribute], [start_date], [num_days|end_date], [interval])

Sample usage:

=GOOGLEFINANCE("GOOG", "price", DATE(2014,1,1), DATE(2014,12,31), "DAILY")
=GOOGLEFINANCE("GOOG","price",TODAY()-30,TODAY())
=GOOGLEFINANCE(A2,A3)
=117.80*Index(GOOGLEFINANCE("CURRENCY:EURGBP", "close", DATE(2014,1,1)), 2, 2)

For instance if you'd like to convert the rate on specific date, here is some more advanced example:

=IF($C2 = "GBP", "", Index(GoogleFinance(CONCATENATE("CURRENCY:", C2, "GBP"), "close", DATE(year($A2), month($A2), day($A2)), DATE(year($A2), month($A2), day($A2)+1), "DAILY"), 2))

where $A2 is your date (e.g. 01/01/2015) and C2 is your currency (e.g. EUR).

See more samples at Docs editors Help at Google.

Just use basename:

echo `basename "$filename"`

The quotes are needed in case $filename contains e.g. spaces.

set "<asp:GridView AutoGenerateColumns="false" ShowHeaderWhenEmpty="true""

showheaderwhenEmpty Property

The preceding 0 is used to indicate a number in base 2, 8, or 16.

In my opinion, 0x was chosen to indicate hex because 'x' sounds like hex.

Just my opinion, but I think it makes sense.

Good Day!

" once the info is added to the DB, should I delete the tuple? i mean i dont need the tuple anymore."

No.

Generally, there's no reason to delete anything. There are some special cases for deleting, but they're very, very rare.

Simply define a narrow scope (i.e., a function definition or a method function in a class) and the objects will be garbage collected at the end of the scope.

Don't worry about deleting anything.

[Note. I worked with a guy who -- in addition to trying to delete objects -- was always writing "reset" methods to clear them out. Like he was going to save them and reuse them. Also a silly conceit. Just ignore the objects you're no longer using. If you define your functions in small-enough blocks of code, you have nothing more to think about.]

Here is my attempt:

Function RegParse(ByVal pattern As String, ByVal html As String)
    Dim regex   As RegExp
    Set regex = New RegExp

    With regex
        .IgnoreCase = True  'ignoring cases while regex engine performs the search.
        .pattern = pattern  'declaring regex pattern.
        .Global = False     'restricting regex to find only first match.

        If .Test(html) Then         'Testing if the pattern matches or not
            mStr = .Execute(html)(0)        '.Execute(html)(0) will provide the String which matches with Regex
            RegParse = .Replace(mStr, "$1") '.Replace function will replace the String with whatever is in the first set of braces - $1.
        Else
            RegParse = "#N/A"
        End If

    End With
End Function

In Swift, you just need

self.tableView.scrollToNearestSelectedRowAtScrollPosition(UITableViewScrollPosition.Bottom, animated: true)

to make it automatically scroll to the buttom

Only for using as a value:

x = 3 if a==2 else 0

or

return 3 if a==2 else 0

Unlike C, Java allows using the % for both integer and floating point and (unlike C89 and C++) it is well-defined for all inputs (including negatives):

From JLS §15.17.3:

The result of a floating-point remainder operation is determined by the rules of IEEE arithmetic:

• If either operand is NaN, the result is NaN.
• If the result is not NaN, the sign of the result equals the sign of the dividend.
• If the dividend is an infinity, or the divisor is a zero, or both, the result is NaN.
• If the dividend is finite and the divisor is an infinity, the result equals the dividend.
• If the dividend is a zero and the divisor is finite, the result equals the dividend.
• In the remaining cases, where neither an infinity, nor a zero, nor NaN is involved, the floating-point remainder r from the division of a dividend n by a divisor d is defined by the mathematical relation r=n-(d·q) where q is an integer that is negative only if n/d is negative and positive only if n/d is positive, and whose magnitude is as large as possible without exceeding the magnitude of the true mathematical quotient of n and d.

So for your example, 0.5/0.3 = 1.6... . q has the same sign (positive) as 0.5 (the dividend), and the magnitude is 1 (integer with largest magnitude not exceeding magnitude of 1.6...), and r = 0.5 - (0.3 * 1) = 0.2

You could use apply() and do something like this

df['que'] = df.apply(lambda x : x['one'] if x['one'] >= x['two'] and x['one'] <= x['three'] else "", axis=1)

or if you prefer not to use a lambda

def que(x):
    if x['one'] >= x['two'] and x['one'] <= x['three']:
        return x['one']
    return ''
df['que'] = df.apply(que, axis=1)

All you should need to do is:

# if the file in the right place isn't already committed:
git add <path to desired file>

# remove the "both deleted" file from the index:
git rm --cached ../public/images/originals/dog.ai

# commit the merge:
git commit

ToString("X2") prints the input in Hexadecimal

before using MongoDB you have to run it locally to do that:

• go to bin folder you will find at C:\Program Files\MongoDB\Server\4.2\bin
• open mongod.exe. will open a new terminal with server details.
• open mongo.exe. will open the shell which allows you to interact with the database.

Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)

import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1

u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0

#option 1
#keep index of t
u.index = t.index 

#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)

#now concat will keep number of rows 
r=pd.concat([t,u], axis=1)

If you're looking for a specific type of control you could use a recursive loop like this one - http://weblogs.asp.net/eporter/archive/2007/02/24/asp-net-findcontrol-recursive-with-generics.aspx

Here's an example I made that returns all controls of the given type

/// <summary>
/// Finds all controls of type T stores them in FoundControls
/// </summary>
/// <typeparam name="T"></typeparam>
private class ControlFinder<T> where T : Control 
{
    private readonly List<T> _foundControls = new List<T>();
    public IEnumerable<T> FoundControls
    {
        get { return _foundControls; }
    }    

    public void FindChildControlsRecursive(Control control)
    {
        foreach (Control childControl in control.Controls)
        {
            if (childControl.GetType() == typeof(T))
            {
                _foundControls.Add((T)childControl);
            }
            else
            {
                FindChildControlsRecursive(childControl);
            }
        }
    }
}

The query below works only when searching for dependencies on a table and not those on a column:

EXEC sp_depends @objname = N'TableName';

However, the following query is the best option if you want to search for all sorts of dependencies, it does not miss any thing. It actually gives more information than required.

 select distinct
        so.name
        --, text 
  from 
       sysobjects so, 
       syscomments sc 
  where 
     so.id = sc.id 
     and lower(text) like '%organizationtypeid%'
  order by so.name

In your pattern, you simply want to match all text between the two tags. Thus, you could use for example a [\w\W] to match all characters.

function getTextBetweenTags($string, $tagname) {
    $pattern = "/<$tagname>([\w\W]*?)<\/$tagname>/";
    preg_match($pattern, $string, $matches);
    return $matches[1];
}

String[] result = "Stack Me 123 Heppa1 oeu".split("**(?<=\\G.{1})**");
System.out.println(java.util.Arrays.toString(result));

StartsWith

a) left(@edition, 15) = 'Express Edition'
b) charindex('Express Edition', @edition) = 1

Contains

charindex('Express Edition', @edition) >= 1

Examples

left function

set @isExpress = case when left(@edition, 15) = 'Express Edition' then 1 else 0 end

iif function (starting with SQL Server 2012)

set @isExpress = iif(left(@edition, 15) = 'Express Edition', 1, 0);

charindex function

set @isExpress = iif(charindex('Express Edition', @edition) = 1, 1, 0);

Add !important rule to display: table of your .v-center class.

.v-center {
    display:table !important;

Your display property is being overridden by bootstrap to display: block.

I can't add a comment above as I do not have enough reputation, but the above answer was nearly perfect for me, except I had to add

type: "POST"

to the .ajax call. I was scratching my head for a few minutes trying to figure out what I had done wrong, that's all it needed and works a treat. So this is the whole snippet:

Full credit to the answer above me, this is just a small tweak to that. This is just in case anyone else gets stuck and can't see the obvious.

  $.ajax({
    url: 'Your url here',
    data: formData,
    type: "POST", //ADDED THIS LINE
    // THIS MUST BE DONE FOR FILE UPLOADING
    contentType: false,
    processData: false,
    // ... Other options like success and etc
})

If you are using macOS Sierra and the file doesn't exists, run

mysql --help or mysql --help | grep my.cnf

to see the possible locations and loading/reading sequence of my.cnf for mysql then create my.cnf file in one of the suggested directories then add the following line

[mysqld] sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

You can sudo touch /{preferred-path}/my.cnf then edit the file to add sql mode by

sudo nano /{preferred-path}/my.cnf

Then restart mysql, voilaah you are good to go. happy coding

This is what I did: see on Codepen

var somedate = 1473888180593;
var myStartDate;
//var myStartDate = somedate - durationInMuntes;

myStartDate = new Date(dateAfterSubtracted('minutes', 100));

alert("The event will start on " + myStartDate.toDateString() + " at " + myStartDate.toTimeString());

function dateAfterSubtracted(range, amount){
    var now = new Date();
    if(range === 'years'){
        return now.setDate(now.getYear() - amount);
    }
    if(range === 'months'){
        return now.setDate(now.getMonth() - amount);
    }
    if(range === 'days'){
        return now.setDate(now.getDate() - amount);
    }
    if(range === 'hours'){
        return now.setDate(now.getHours() - amount);
    }
    if(range === 'minutes'){
        return now.setDate(now.getMinutes() - amount);
    }
    else {
        return null;
    }

While compiling in RHEL 6.2 (x86_64), I installed both 32bit and 64bit libstdc++-dev packages, but I had the "c++config.h no such file or directory" problem.

Resolution:

The directory /usr/include/c++/4.4.6/x86_64-redhat-linux was missing.

I did the following:

cd /usr/include/c++/4.4.6/
mkdir x86_64-redhat-linux
cd x86_64-redhat-linux
ln -s ../i686-redhat-linux 32

I'm now able to compile 32bit binaries on a 64bit OS.

I suggest you do some experiments using "make". Here is a simple demo, showing the difference between = and :=.

/* Filename: Makefile*/
x := foo
y := $(x) bar
x := later

a = foo
b = $(a) bar
a = later

test:
    @echo x - $(x)
    @echo y - $(y)
    @echo a - $(a)
    @echo b - $(b)

make test prints:

x - later
y - foo bar
a - later
b - later bar

Check more elaborate explanation here

You have various possibilies. The most simple and the most ugly is:

XAML

<Button Name="cmdCommand" Click="Button_Clicked" Content="Command"/> 

Code Behind

private void Button_Clicked(object sender, RoutedEventArgs e) { 
    FrameworkElement fe=sender as FrameworkElement;
    ((YourClass)fe.DataContext).DoYourCommand();     
} 

Another solution (better) is to provide a ICommand-property on your YourClass. This command will have already a reference to your YourClass-object and therefore can execute an action on this class.

XAML

<Button Name="cmdCommand" Command="{Binding YourICommandReturningProperty}" Content="Command"/>

Because during writing this answer, a lot of other answers were posted, I stop writing more. If you are interested in one of the ways I showed or if you think I have made a mistake, make a comment.

I wouldn't recommend any of these methods. Instead, put it within its own namespace.

class Post < ActiveRecord::Base
  def clean_input
    self.input = Helpers.sanitize(self.input, :tags => %w(b i u))
  end

  module Helpers
    extend ActionView::Helpers::SanitizeHelper
  end
end

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

As in this forum post by Gonzalo Medina, a third way may be:

\documentclass{article}
\usepackage{caption}

\DeclareCaptionType{equ}[][]
%\captionsetup[equ]{labelformat=empty}

\begin{document}

Some text

\begin{equ}[!ht]
  \begin{equation}
    a=b+c
  \end{equation}
\caption{Caption of the equation}
\end{equ}

Some other text
 
\end{document}

More details of the commands used from package caption: here.

A screenshot of the output of the above code:

I recommend using http://jsbeautifier.org/ - if you paste your code snippet into it and press beautify, the error is immediately visible.

You could split the string on the whitespace and then re-add it, since you know its in between every one of the entries.

var string = "text to split";
    string = string.split(" ");
var stringArray = new Array();
for(var i =0; i < string.length; i++){
    stringArray.push(string[i]);
    if(i != string.length-1){
        stringArray.push(" ");
    }
}

Update: Removed trailing space.

Utilities.sleep(milliseconds) creates a 'pause' in program execution, meaning it does nothing during the number of milliseconds you ask. It surely slows down your whole process and you shouldn't use it between function calls. There are a few exceptions though, at least that one that I know : in SpreadsheetApp when you want to remove a number of sheets you can add a few hundreds of millisecs between each deletion to allow for normal script execution (but this is a workaround for a known issue with this specific method). I did have to use it also when creating many sheets in a spreadsheet to avoid the Browser needing to be 'refreshed' after execution.

Here is an example :

function delsheets(){
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var numbofsheet=ss.getNumSheets();// check how many sheets in the spreadsheet
  for (pa=numbofsheet-1;pa>0;--pa){ 
    ss.setActiveSheet(ss.getSheets()[pa]);
    var newSheet = ss.deleteActiveSheet(); // delete sheets begining with the last one
    Utilities.sleep(200);// pause in the loop for 200 milliseconds
  }
  ss.setActiveSheet(ss.getSheets()[0]);// return to first sheet as active sheet (useful in 'list' function)
}

The clean, install and deploy phases are valid lifecycle phases and invoking them will trigger all the phases preceding them, and the goals bound to these phases.

mvn clean install

This command invokes the clean phase and then the install phase sequentially:

• clean: removes files generated at build-time in a project's directory (target by default)
• install: installs the package into the local repository, for use as a dependency in other projects locally.

mvn deploy

This command invokes the deploy phase:

• deploy: copies the final package to the remote repository for sharing with other developers and projects.

mvn release

This is not a valid phase nor a goal so this won't do anything. But if refers to the Maven Release Plugin that is used to automate release management. Releasing a project is done in two steps: prepare and perform. As documented:

Preparing a release goes through the following release phases:

• Check that there are no uncommitted changes in the sources
• Check that there are no SNAPSHOT dependencies
• Change the version in the POMs from x-SNAPSHOT to a new version (you will be prompted for the versions to use)
• Transform the SCM information in the POM to include the final destination of the tag
• Run the project tests against the modified POMs to confirm everything is in working order
• Commit the modified POMs
• Tag the code in the SCM with a version name (this will be prompted for)
• Bump the version in the POMs to a new value y-SNAPSHOT (these values will also be prompted for)
• Commit the modified POMs

And then:

Performing a release runs the following release phases:

• Checkout from an SCM URL with optional tag
• Run the predefined Maven goals to release the project (by default, deploy site-deploy)

Developers can take following steps to prevent an APK from theft somehow,

• the most basic way is to use tools like ProGuard to obfuscate their code, but up until now, it has been quite difficult to completely prevent someone from decompiling an app.

• Also I have heard about a tool HoseDex2Jar. It stops Dex2Jar by inserting harmless code in an Android APK that confuses and disables Dex2Jar and protects the code from decompilation. It could somehow prevent hackers from decompiling an APK into readable java code.

• Use some server side application to communicate with the application only when it is needed. It could help prevent the important data.

At all, you can not completely protect your code from the potential hackers. Somehow, you could make it difficult and a bit frustrating task for them to decompile your code. One of the most efficient way is to write in native code(C/C++) and store it as compiled libraries.

Another way is to make your user a password-less sudo user.

Type the following on command line:

sudo visudo

Then add the following and replace the <username> with yours:

<username> ALL=(ALL) NOPASSWD: ALL

This will allow the user to execute sudo command without having to ask for password (including application launched by the said user. This might be a security risk though

According to the documentation:

Field.choices

An iterable (e.g., a list or tuple) consisting itself of iterables of exactly two items (e.g. [(A, B), (A, B) ...]) to use as choices for this field. If this is given, the default form widget will be a select box with these choices instead of the standard text field.

The first element in each tuple is the actual value to be stored, and the second element is the human-readable name.

So, your code is correct, except that you should either define variables JANUARY, FEBRUARY etc. or use calendar module to define MONTH_CHOICES:

import calendar
...

class MyModel(models.Model):
    ...

    MONTH_CHOICES = [(str(i), calendar.month_name[i]) for i in range(1,13)]

    month = models.CharField(max_length=9, choices=MONTH_CHOICES, default='1')

They're used in different places. group by modifies the entire query, like:

select customerId, count(*) as orderCount
from Orders
group by customerId

But partition by just works on a window function, like row_number:

select row_number() over (partition by customerId order by orderId)
    as OrderNumberForThisCustomer
from Orders

A group by normally reduces the number of rows returned by rolling them up and calculating averages or sums for each row. partition by does not affect the number of rows returned, but it changes how a window function's result is calculated.

Alternatively you can just look inside

I have the same problem. Following the first step above i was able to clone, but I cannot do anything else. Can't fetch, pull or checkout old branches.

Each command runs much slower than usual, then dies after compressing the objects.

I:\dev [master +0 ~6 -0]> git fetch --unshallow
remote: Counting objects: 645483, done.
remote: Compressing objects: 100% (136865/136865), done.

error: RPC failed; result=18, HTTP code = 20082 MiB | 6.26 MiB/s

fatal: early EOF

fatal: The remote end hung up unexpectedly

fatal: index-pack failed

This also happens when your ref's are using too much memory. Pruning the memory fixed this for me. Just add a limit to what you fetching like so ->

git fetch --depth=100

This will fetch the files but with the last 100 edits in their histories. After this, you can do any command just fine and at normal speed.

You can chain methods off the returned object, so you can immediately close the file you just opened in a single statement.

File.Open("filename", FileMode.Create).Close();

This error may also be brought about if the symbolic link is to a dynamic library, .so, but for legacy reasons -static appears among the link flags. If so, try removing it.

x / y

quotient of x and y

x // y 

(floored) quotient of x and y

To do this for oracle sql, the syntax would be:

You can use double open brackets and double closing brackets which will only show one bracket on your page.

Just one command did the work

netsh http add iplisten 127.0.0.1

Initially, I was running php composer.phar self-update and got the same error message.

As a resolve, you should use composer command directly after install it.From the command prompt, just type composer and press enter.

If composer is installed correctly then you should able to see a lot of suggestion and command list from composer.

If you are up to this point then you should able to run composer self-update directly.

Your method showFile() declares that it can throw an IOException. Since this is a checked exception, any call to showFile() method must handle the exception somehow. One option is to wrap the call to showFile() in a try-catch block.

 try {
     showFile();
 }
 catch(IOException e) {
    // Code to handle an IOException here
 }

You can see value inside [object Object] like this

Alert.alert(  JSON.stringify(userDate)  );

Try like this

    realm.write(() => {
       const userFormData = realm.create('User',{
       user_email: value.username,
       user_password: value.password,
      });
     });

      const userDate = realm.objects('User').filtered('user_email == $0', value.username.toString(), );
      Alert.alert(  JSON.stringify(userDate)  );

I just wanted to add that "Include" is part of eager loading. It is described in Entity Framework 6 tutorial by Microsoft. Here is the link: https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application

Excerpt from the linked page:

Here are several ways that the Entity Framework can load related data into the navigation properties of an entity:

Lazy loading. When the entity is first read, related data isn't retrieved. However, the first time you attempt to access a navigation property, the data required for that navigation property is automatically retrieved. This results in multiple queries sent to the database — one for the entity itself and one each time that related data for the entity must be retrieved. The DbContext class enables lazy loading by default.

Eager loading. When the entity is read, related data is retrieved along with it. This typically results in a single join query that retrieves all of the data that's needed. You specify eager loading by using the Include method.

Explicit loading. This is similar to lazy loading, except that you explicitly retrieve the related data in code; it doesn't happen automatically when you access a navigation property. You load related data manually by getting the object state manager entry for an entity and calling the Collection.Load method for collections or the Reference.Load method for properties that hold a single entity. (In the following example, if you wanted to load the Administrator navigation property, you'd replace Collection(x => x.Courses) with Reference(x => x.Administrator).) Typically you'd use explicit loading only when you've turned lazy loading off.

Because they don't immediately retrieve the property values, lazy loading and explicit loading are also both known as deferred loading.

For some reason Brice's answer is not working for me. I was able to manipulate it a bit to get it to work. It might just be because I have a newer version of PowerMock. I'm using 1.6.5.

        }
    }

    private boolean doTheGamble(String whatever, int binary) {
        Random random = new Random(System.nanoTime());
        boolean gamble = random.nextBoolean();
        return gamble;

In order to Join multicast group Python uses native OS socket interface. Due to portability and stability of Python environment many of socket options are directly forwarded to native socket setsockopt call. Multicast mode of operation such as joining and dropping group membership can be accomplished by setsockopt only.

Basic program for receiving multicast IP packet can look like:

from socket import *

multicast_port  = 55555
multicast_group = "224.1.1.1"
interface_ip    = "10.11.1.43"

s = socket(AF_INET, SOCK_DGRAM )
s.bind(("", multicast_port ))
mreq = inet_aton(multicast_group) + inet_aton(interface_ip)
s.setsockopt(IPPROTO_IP, IP_ADD_MEMBERSHIP, str(mreq))

while 1:
    print s.recv(1500)

Firstly it creates socket, binds it and triggers triggers multicast group joining by issuing setsockopt. At very end it receives packets forever.

Sending multicast IP frames is straight forward. If you have single NIC in your system sending such packets does not differ from usual UDP frames sending. All you need to take care of is just set correct destination IP address in sendto() method.

I noticed that lot of examples around Internet works by accident in fact. Even on official python documentation. Issue for all of them are using struct.pack incorrectly. Please be advised that typical example uses 4sl as format and it is not aligned with actual OS socket interface structure.

I will try to describe what happens underneath the hood when exercising setsockopt call for python socket object.

Python forwards setsockopt method call to native C socket interface. Linux socket documentation (see man 7 ip) introduces two forms of ip_mreqn structure for IP_ADD_MEMBERSHIP option. Shortest is form is 8 bytes long and longer is 12 bytes long. Above example generates 8 byte setsockopt call where first four bytes define multicast_group and second four bytes define interface_ip.

Funny, I had to add to this thread.

1) Add a global var on form.show() and clear out the var on form.close()

2) On the parent form add a timer. Keep the child form open and update your data every 10 min.

3) put timer on the child form to go update data on itself.

I am not sure in Razor but in ASPX you do:

 <%if (item.Modify_Date != null)
  {%>
     <%=Html.Encode(String.Format("{0:D}", item.Modify_Date))%>     
<%} %>

There must be something similar in Razor. Hopefully this will help someone.

It should work - as long as the data variable is actually an array containing a dictionary with the key SPORT

NSArray *data = [NSArray arrayWithObject:[NSMutableDictionary dictionaryWithObject:@"foo" forKey:@"BAR"]];    
NSArray *filtered = [data filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"(BAR == %@)", @"foo"]];

Filtered in this case contains the dictionary.

(the %@ does not have to be quoted, this is done when NSPredicate creates the object.)

You can set this programmatically in the controller:-

HttpContext.Current.Server.ScriptTimeout = 300;

Sets the timeout to 5 minutes instead of the default 110 seconds (what an odd default?)

I modified Bootstrap SASS (v3.3.5) based on Rukshan's answer

Add this in the end of the calc-grid-column mixin in mixins/_grid-framework.scss, right below the $type == offset if condition.

@if ($type == offset-right) {
      .col-#{$class}-offset-right-#{$index} {
          margin-right: percentage(($index / $grid-columns));
      }
  }

Modify the make-grid mixin in mixins/_grid-framework.scss to generate the offset-right classes.

// Create grid for specific class
@mixin make-grid($class) {
  @include float-grid-columns($class);
  @include loop-grid-columns($grid-columns, $class, width);
  @include loop-grid-columns($grid-columns, $class, pull);
  @include loop-grid-columns($grid-columns, $class, push);
  @include loop-grid-columns($grid-columns, $class, offset);
  @include loop-grid-columns($grid-columns, $class, offset-right);
}

You can then use the classes like col-sm-offset-right-2 and col-md-offset-right-1

Lots of unnecessary flooring in other answers. If the string is in milliseconds, convert to h:m:s as follows:

function msToTime(s) {
  var ms = s % 1000;
  s = (s - ms) / 1000;
  var secs = s % 60;
  s = (s - secs) / 60;
  var mins = s % 60;
  var hrs = (s - mins) / 60;

  return hrs + ':' + mins + ':' + secs + '.' + ms;
}

If you want it formatted as hh:mm:ss.sss then use:

function msToTime(s) {_x000D_
_x000D_
  // Pad to 2 or 3 digits, default is 2_x000D_
  function pad(n, z) {_x000D_
    z = z || 2;_x000D_
    return ('00' + n).slice(-z);_x000D_
  }_x000D_
_x000D_
  var ms = s % 1000;_x000D_
  s = (s - ms) / 1000;_x000D_
  var secs = s % 60;_x000D_
  s = (s - secs) / 60;_x000D_
  var mins = s % 60;_x000D_
  var hrs = (s - mins) / 60;_x000D_
_x000D_
  return pad(hrs) + ':' + pad(mins) + ':' + pad(secs) + '.' + pad(ms, 3);_x000D_
}_x000D_
_x000D_
console.log(msToTime(55018))

Using some recently added language features, the pad function can be more concise:

function msToTime(s) {_x000D_
    // Pad to 2 or 3 digits, default is 2_x000D_
  var pad = (n, z = 2) => ('00' + n).slice(-z);_x000D_
  return pad(s/3.6e6|0) + ':' + pad((s%3.6e6)/6e4 | 0) + ':' + pad((s%6e4)/1000|0) + '.' + pad(s%1000, 3);_x000D_
}_x000D_
_x000D_
// Current hh:mm:ss.sss UTC_x000D_
console.log(msToTime(new Date() % 8.64e7))

I believe the safest and most accurate method of retrieving the inserted id would be using the output clause.

for example (taken from the following MSDN article)

USE AdventureWorks2008R2;
GO
DECLARE @MyTableVar table( NewScrapReasonID smallint,
                           Name varchar(50),
                           ModifiedDate datetime);
INSERT Production.ScrapReason
    OUTPUT INSERTED.ScrapReasonID, INSERTED.Name, INSERTED.ModifiedDate
        INTO @MyTableVar
VALUES (N'Operator error', GETDATE());

--Display the result set of the table variable.
SELECT NewScrapReasonID, Name, ModifiedDate FROM @MyTableVar;
--Display the result set of the table.
SELECT ScrapReasonID, Name, ModifiedDate 
FROM Production.ScrapReason;
GO

Short Answer:

You get "close existing connections to destination database" option only in "Databases context >> Restore Wizard" and NOT ON context of any particular database.

Long Answer:

Right Click on the Databases under your Server-Name as shown below:

and select the option: "Restore Database..." from it.

In the "Restore Database" wizard,

1. select one of your databases to restore
2. in the left vertical menu, click on "Options"

Here you can find the checkbox saying, "close existing connections to destination database"

Just check it, and you can proceed for the restore operation.

It automatically will resume all connections after completion of the Restore.

Windows 10 Home Edition does not have Local Users and Groups option so that is the reason you aren't able to see that in Computer Management.

You can use User Accounts by pressing Window+R, typing netplwiz and pressing OK as described here.

Use order by like this:

return User::orderBy('name', 'DESC')
    ->orderBy('surname', 'DESC')
    ->orderBy('email', 'DESC')
    ...
    ->get();

Access-Engine does not support

SELECT count(DISTINCT....) FROM ...

You have to do it like this:

SELECT count(*) 
FROM
(SELECT DISTINCT Name FROM table1)

Its a little workaround... you're counting a DISTINCT selection.

After all files have been added, the next step is a "git commit".

"git status" will suggest what to do: files yet to add are listed at the bottom, and once they are all done, it will suggest a commit at the top, where it explains the merge status of the current branch.

I am also having This Error!

Then i change this

$("#from").datepicker('disable');

to This

$("#from").datepicker("disable");

mistake : single and double quotes..

Now its Work fine for me..

It is a sub-set of the .NET Framework, started with the Compact Framework edition. It progressed into Silverlight, Windows Store and Windows Phone. It focused on keeping the deployment small, suitable for quick downloads and devices with limited storage capabilities. And it is easier to bring up on non-Windows platforms, and surely this was the reason it was chosen as the open sourced edition. The "difficult" and "expensive" parts of the CLR and the base class libraries are omitted.

Otherwise, it is always easy to recognize when you target such a framework version, because lots of goodies will be missing. You'll be using a distinct set of reference assemblies that only expose what is supported by the runtime. It is stored on your machine in the C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETCore directory.

Update: after the .NET Core 2.0 release I've seen some representative numbers that gives a decent insight. They have been hard at work back-porting framework APIs to .NET Core over the past two years. .NET Core 1.0 originally supported 13,000 APIs. .NET Core 2.0 added 20,000 APIs, bringing the total to 32,000 and allowing about 70% of existing NuGet packages to be ported. There are a set of APIs that are too heavily wedded to Windows to be easy to port to Linux and MacOS. Covered by the recently released Windows Compatibility Pack, it adds another 20,000 APIs.

As described above I executed:

sc delete ServiceName

However this didn't work as I was executing it from PowerShell.

When using PowerShell you must specify the full path to sc.exe because PowerShell has a default alias for sc assigning it to Set-Content. Since it's a valid command it doesn't actually show an error message.

To resolve this I executed it as follows:

C:\Windows\System32\sc.exe delete ServiceName

Here's a solution where security checking is disabled (for example, conversing with the localhost) Also, some of the solutions I've seen now contain deprecated methods and such.

Update November 2015:

In Eclipse Mars 4.5.1, line numbers are (annoyingly) turned off by default again. Follow the below instructions to enable it.

Update December 2013:

Lars Vogel just published on his blog:

Line numbers are default in Eclipse SDK Luna (4.4) as of today

(December 10, 2013)

We conducted a user survey if users want to have line numbers activated in text editors in the Eclipse IDE by default.
The response was very clear:

YES : 80.07% (1852 responses)
NO  : 19.93% (461 responses)
Total  : 2313
Skipped:   15

With Bug 421313, Review - Line number should be activated by default, we enabled it for the Eclipse SDK build, I assume other Eclipse packages will follow.

Update August 2014

Line number default length is now 120 (instead of 80) for Eclipse Mars 4.5M1.
See "How to customize Eclipse's text editor code formating".

Original answer (March 2009)

To really have it by default, you can write a script which ensure, before launching eclipse, that:
[workspace]\.metadata\.plugins\org.eclipse.core.runtime\.settings\org.eclipse.ui.editors.prefs does contain:

lineNumberRuler=true

(with [workspace] being the root directory of your eclipse workspace)
Then eclipse will be opened with "line numbers shown 'by default' "

Otherwise, you can also type 'CTRL+1' and then "line", which will give you access to the command "Show line numbers"
(that will switch to option "show line numbers" in the text editors part of the option.

Or you can just type "numb" in Windows Preferences to access to the Text Editor part:

^{Picture from "How to display line numbers in Eclipse" of blog "Mkyong.com"}

And here is how to report the position of the first character off the found substring:

Replace this line in the above code:

printf("%s",substring,"\n");

with:

printf("substring %s was found at position %d \n", substring,((int) (substring - mainstring)));

I tried sehe's answer and it did not work.

To find the commits that have not been merged simply use:

git log feature-branch ^master --no-merges

The simplest supported solution is to either use margin

.element {
  display: block;
  margin: 0px auto;
}

Or use a second container around the element that has this margin applied. This will somewhat have the effect of padding: 0px auto if it did exist.

CSS

.element_wrapper {
  display: block;
  margin: 0px auto;
}
.element {
  background: blue;
}

HTML

<div class="element_wrapper">
  <div class="element">
    Hello world
  </div>
</div>

I'll share my very simple code for sample purpose. Hope it will help someone like me searching for quick code reference. My goal was to receive rsa signature from backend, then validate against input string using public key and store locally for future periodic verifications. Here is main part used for signature verification:

        ...
        var signature = Get(url); // base64_encoded signature received from server
        var inputtext= "inputtext"; // this is main text signature was created for
        bool result = VerifySignature(inputtext, signature);
        ...

    private bool VerifySignature(string input, string signature)
    {
        var result = false;
        using (var cps=new RSACryptoServiceProvider())
        {
            // converting input and signature to Bytes Arrays to pass to VerifyData rsa method to verify inputtext was signed using privatekey corresponding to public key we have below
            byte[] inputtextBytes = Encoding.UTF8.GetBytes(input);
            byte[] signatureBytes  = Convert.FromBase64String(signature);

            cps.FromXmlString("<RSAKeyValue><Modulus>....</Modulus><Exponent>....</Exponent></RSAKeyValue>"); // xml formatted publickey
            result = cps.VerifyData(inputtextBytes , new SHA1CryptoServiceProvider(), signatureBytes  );
        }

        return result;
    }

if you have the BluetoothDevice object you can create bond(pair) from api 19 onwards with bluetoothDevice.createBond() method.

Edit

for callback, if the request was accepted or denied you will have to create a BroadcastReceiver with BluetoothDevice.ACTION_BOND_STATE_CHANGED action

Use the following the Call the Action Link:

<%= Html.ActionLink("Click Here" , "ActionName","ContorllerName" )%>

For submitting the form values use:

 <% using (Html.BeginForm("CustomerSearchResults", "Customer"))
   { %>
      <input type="text" id="Name" />
      <input type="submit" class="dASButton" value="Submit" />
   <% } %>

It will submit the Data to Customer Controller and CustomerSearchResults Action.

First of all declare a variable to identify your active UITextField.

Step 1:-

Like as var activeTextField: UITextField?

Step 2:- After this add these two lines in viewDidLoad.

NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillShow(_:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)

NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardWillHide(_:)), name: NSNotification.Name.UIKeyboardWillHide, object: nil)

Step 3:-

Now define these two methods in your controller class.

func keyboardWillShow(_ notification: NSNotification) {

    self.scrollView.isScrollEnabled = true
    var info = notification.userInfo!
    let keyboardSize = (info[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue.size
    let contentInsets : UIEdgeInsets = UIEdgeInsetsMake(0.0, 0.0, keyboardSize!.height, 0.0)

    self.scrollView.contentInset = contentInsets
    self.scrollView.scrollIndicatorInsets = contentInsets

    var aRect : CGRect = self.view.frame
    aRect.size.height -= keyboardSize!.height
    if let activeField = self.activeField {
        if (!aRect.contains(activeField.frame.origin)){
            self.scrollView.scrollRectToVisible(activeField.frame, animated: true)
        }
    }
}


func keyboardWillHide(_ notification: NSNotification) {

    let contentInsets : UIEdgeInsets = UIEdgeInsetsMake(0.0, 0.0, 0.0, 0.0)
    self.scrollView.contentInset = contentInsets
    self.scrollView.scrollIndicatorInsets = contentInsets
    self.view.endEditing(true)
    self.scrollView.isScrollEnabled = true
}


func textFieldDidBeginEditing(_ textField: UITextField){

    activeField = textField
}

func textFieldDidEndEditing(_ textField: UITextField){

    activeField = nil
}

I also had this issue because I had another console window open that was running the app and I was attempting to re-run yarn start in another console window.

The first yarn executing prevented the second from writing. So I just killed the first process and it worked

print_r() can print out value but also if second flag parameter is passed and is TRUE - it will return printed result as string and nothing send to standard output. About var_dump. If XDebug debugger is installed so output results will be formatted in much more readable and understandable way.
