Please see Pierre L'Ecuyer's work going back to the late 1980s and early 1990s. There are others as well. Creating a (pseudo) random number generator on your own, if you are not an expert, is pretty dangerous, because there is a high likelihood of either the results not being statistically random or in having a small period. Pierre (and others) have put together some good (pseudo) random number generators that are easy to implement. I use one of his LFSR generators.

I've been using Typescript in my current angular project for about a year and a half and while there are a few issues with definitions every now and then the DefinitelyTyped project does an amazing job at keeping up with the latest versions of most popular libraries.

Having said that there is a definite learning curve when transitioning from vanilla JavaScript to TS and you should take into account the ability of you and your team to make that transition. Also if you are going to be using angular 1.x most of the examples you will find online will require you to translate them from JS to TS and overall there are not a lot of resources on using TS and angular 1.x together right now.

If you plan on using angular 2 there are a lot of examples using TS and I think the team will continue to provide most of the documentation in TS, but you certainly don't have to use TS to use angular 2.

ES6 does have some nice features and I personally plan on getting more familiar with it but I would not consider it a production-ready language at this point. Mainly due to a lack of support by current browsers. Of course, you can write your code in ES6 and use a transpiler to get it to ES5, which seems to be the popular thing to do right now.

Overall I think the answer would come down to what you and your team are comfortable learning. I personally think both TS and ES6 will have good support and long futures, I prefer TS though because you tend to get language features quicker and right now the tooling support (in my opinion) is a little better.

There is a firewall blocking the connection or the process that is hosting the service is not listening on that port. Or it is listening on a different port.

This is one more option to find the element for above question

$("#tbIntervalos").find('td[id="'+horaInicial+'"]')

How about:

Random generator = new Random();
int i = 10 - generator.nextInt(10);

My problem was using the integrated terminal in VS Code. That showed me a different path setting (and so tools path instead of emulator path was shown in the first place). All you need is to change the global vscode settings by using the correct bash as described here: https://stackoverflow.com/a/53971796/3437868

This approach will work ONLY when the total duration is less than 24 hours:

var now  = "04/09/2013 15:00:00";
var then = "04/09/2013 14:20:30";

moment.utc(moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"))).format("HH:mm:ss")

// outputs: "00:39:30"

If you have 24 hours or more, the hours will reset to zero with the above approach, so it is not ideal.

If you want to get a valid response for durations of 24 hours or greater, then you'll have to do something like this instead:

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = Math.floor(d.asHours()) + moment.utc(ms).format(":mm:ss");

// outputs: "48:39:30"

Note that I'm using the utc time as a shortcut. You could pull out d.minutes() and d.seconds() separately, but you would also have to zeropad them.

This is necessary because the ability to format a duration objection is not currently in moment.js. It has been requested here. However, there is a third-party plugin called moment-duration-format that is specifically for this purpose:

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);
var s = d.format("hh:mm:ss");

// outputs: "48:39:30"

ng set --global defaults.styleExt=scss is deprecated since ng6. You will get this message:

get/set have been deprecated in favor of the config command

You should use:

ng config schematics.@schematics/angular:component '{ styleext: "scss"}'

If you want to target a specific project (replace {project} with your project's name):

ng config projects.{project}.schematics.@schematics/angular:component '{ styleext: "scss"}'

Markup declarations can affect the content of the document, as passed from an XML processor to an application; examples are attribute defaults and entity declarations. The standalone document declaration, which may appear as a component of the XML declaration, signals whether or not there are such declarations which appear external to the document entity or in parameter entities. [Definition: An external markup declaration is defined as a markup declaration occurring in the external subset or in a parameter entity (external or internal, the latter being included because non-validating processors are not required to read them).]

I just had the same problem and all I did was delete the user log in credentials in sql server using another user id and adding them back.

Getting the ball rolling with this community wiki answer. Feel free to edit me with your improvements.

• ws WebSocket server and client for node.js. One of the fastest libraries if not the fastest one.

• websocket-node WebSocket server and client for node.js

• websocket-driver-node WebSocket server and client protocol parser node.js - used in faye-websocket-node

• faye-websocket-node WebSocket server and client for node.js - used in faye and sockjs

• socket.io WebSocket server and client for node.js + client for browsers + (v0 has newest to oldest fallbacks, v1 of Socket.io uses engine.io) + channels - used in stack.io. Client library tries to reconnect upon disconnection.

• sockjs WebSocket server and client for node.js and others + client for browsers + newest to oldest fallbacks

• faye WebSocket server and client for node.js and others + client for browsers + fallbacks + support for other server-side languages

• deepstream.io clusterable realtime server that handles WebSockets & TCP connections and provides data-sync, pub/sub and request/response

• socketcluster WebSocket server cluster which makes use of all CPU cores on your machine. For example, if you were to use an xlarge Amazon EC2 instance with 32 cores, you would be able to handle almost 32 times the traffic on a single instance.

• primus Provides a common API for most of the libraries above for easy switching + stability improvements for all of them.

When to use:

• use the basic WebSocket servers when you want to use the native WebSocket implementations on the clientside, beware of the browser incompatabilities

• use the fallback libraries when you care about browser fallbacks

• use the full featured libraries when you care about channels

• use primus when you have no idea about what to use, are not in the mood for rewriting your application when you need to switch frameworks because of changing project requirements or need additional connection stability.

Where to test:

Firecamp is a GUI testing environment for SocketIO, WS and all major real-time technology. Debug the real-time events while you're developing it.

For your case, just use:

var votevalue = +$(this).data('votevalue');

There are some ways to convert string to number in javascript.

The best way:

var str = "1";
var num = +str; //simple enough and work with both int and float

You also can:

var str = "1";
var num = Number(str); //without new. work with both int and float

or

var str = "1";
var num = parseInt(str,10); //for integer number
var num = parseFloat(str); //for float number

DON'T:

var str = "1";
var num = new Number(str);  //num will be an object. typeof num == 'object'

Use parseInt only for special case, for example

var str = "ff";
var num = parseInt(str,16); //255

var str = "0xff";
var num = parseInt(str); //255

A common PyTorch convention is to save models using either a .pt or .pth file extension.

Save/Load Entire Model Save:

path = "username/directory/lstmmodelgpu.pth"
torch.save(trainer, path)

Load:

Model class must be defined somewhere

model = torch.load(PATH)
model.eval()

In Swift 2.0 you can use this method:

    let registrationView = LMRegistration()
    self.presentViewController(registrationView, animated: true, completion: nil)

I think you need the SCHEDULER_ADMIN role to see the dba_scheduler tables (however this may grant you too may rights)

For a List of Links

The other answers provide some good ways of adding line breaks, depending on the situation. But it should be noted that the :after selector is one of the better ways to do this for CSS control over lists of links (and similar things), for reasons noted below.

Here's an example, assuming a table of contents:

<style type="text/css">
    .toc a:after{ content: "\a"; white-space: pre; }
</style>

<span class="toc">
    <a href="#a1">Item A1</a> <a href="#a2">Item A2</a>
    <a href="#b1">Item B1</a> <a href="#b2">Item B2</a>
</span>

And here's Simon_Weaver's technique, which is simpler and more compatible. It doesn't separate style and content as much, requires more code, and there may be cases where you want to add breaks after the fact. Still a great solution though, especially for older IE.

<style type="text/css">
    .toc br{ display: none; } /* comment out for horizontal links */
</style>

<span class="toc">
    <a href="#a1">Item A1</a><br/> <a href="#a2">Item A2</a><br/>
    <a href="#b1">Item B1</a><br/> <a href="#b2">Item B2</a><br/>
</span>

Note the advantages of the above solutions:

• No matter the whitespace in the HTML, the output is the same (vs. pre)
• No extra padding is added to the elements (see NickG's display:block comments)
• You can easily switch between horizontal and vertical lists of links with some shared CSS without going into every HTML file for a style change
• No float or clear styles affecting surrounding content
• The style is separate from the content (vs. <br/>, or pre with hard-coded breaks)
• This can also work for loose links using a.toc:after and <a class="toc">
• You can add multiple breaks and even prefix/suffix text

Install pip.

Then install pandas with pip:

pip install pandas

I suggest using a directive on a link.

But its not perfect yet. Watch out for the hashbangs ;)

Here is the javascript for directive:

angular.module('link', []).
  directive('activeLink', ['$location', function (location) {
    return {
      restrict: 'A',
      link: function(scope, element, attrs, controller) {
        var clazz = attrs.activeLink;
        var path = attrs.href;
        path = path.substring(1); //hack because path does not return including hashbang
        scope.location = location;
        scope.$watch('location.path()', function (newPath) {
          if (path === newPath) {
            element.addClass(clazz);
          } else {
            element.removeClass(clazz);
          }
        });
      }
    };
  }]);

and here is how it would be used in html:

<div ng-app="link">
  <a href="#/one" active-link="active">One</a>
  <a href="#/two" active-link="active">One</a>
  <a href="#" active-link="active">home</a>
</div>

afterwards styling with css:

.active { color: red; }

If you have a base class with pure virtual function, make sure your base class constructor and destructor has body otherwise linker fails.

The pack method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame size explicitly by calling setSize or setBounds (which also sets the frame location). In general, using pack is preferable to calling setSize, since pack leaves the frame layout manager in charge of the frame size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.

From Java tutorial

You should also refer to Javadocs any time you need additional information on any Java API

SQL SERVER 2005:

print upper('hello');
print lower('HELLO');

Create = PUT with a new URI
         POST to a base URI returning a newly created URI
Read   = GET
Update = PUT with an existing URI
Delete = DELETE

PUT can map to both Create and Update depending on the existence of the URI used with the PUT.

POST maps to Create.

Correction: POST can also map to Update although it's typically used for Create. POST can also be a partial update so we don't need the proposed PATCH method.

Additionally for gists, it seems you must leave out the username

git remote set-url origin [email protected]:<Project code>

Here is an example that's working for me with MVC and Javascript in the Razor. The first function calls an action via ajax on my controller and passes two parameters.

        function redirectToAction(var1, var2)
        {
            try{

                var url = '../actionnameinsamecontroller/' + routeId;

                $.ajax({
                    type: "GET",
                    url: url,
                    data: { param1: var1, param2: var2 },
                    dataType: 'html',
                    success: function(){
                    },
                    error: function(xhr, ajaxOptions, thrownError){
                        alert(error);
                    }
                });

            }
            catch(err)
            {
                alert(err.message);
            }
        }

Use the ajaxStart to start your progress bar code.

           $(document).ajaxStart(function(){
            try
            {
                // showing a modal
                $("#progressDialog").modal();

                var i = 0;
                var timeout = 750;

                (function progressbar()
                {
                    i++;
                    if(i < 1000)
                    {
                        // some code to make the progress bar move in a loop with a timeout to 
                        // control the speed of the bar
                        iterateProgressBar();
                        setTimeout(progressbar, timeout);
                    }
                }
                )();
            }
            catch(err)
            {
                alert(err.message);
            }
        });

When the process completes close the progress bar

        $(document).ajaxStop(function(){
            // hide the progress bar
            $("#progressDialog").modal('hide');
        });

This one Works for me with asp label control.

 function changeEmaillbl() {


         if (document.getElementById('<%=rbAgency.ClientID%>').checked = true) {
             document.getElementById('<%=lblUsername.ClientID%>').innerHTML = 'Accredited No.:';
         } 
     }

In Chrome (v.56 is what I'm using but I AFAIK this applies generally) you can set title=" " (a single space) and the automatic title text will be overridden and nothing displayed. (If you try to make it just an empty string, though, it will treat it as if it isn't set and add that automatic tooltip text you've been getting).

I haven't tested this in other browsers, because I found it whilst making a Google Chrome Extension. I'm sure once I port things to other browsers, though, I'll see if it works in them (if even necessary), too.

Forr me reason was that I tried to use newest MySQL Workbench 8.x to connect to MySQL Server 5.1 (both running on Windows Server 2012).

When I uninstalled MySQL Workbench 8.x and installed MySQL Workbench 6.3.10 it successfully connected to localhost database

This is the is simplest solution that worked for me.

<div
  contentEditable='true'
  onInput={e => console.log('Text inside div', e.currentTarget.textContent)}
>
Text inside div
</div>

I'd just like to add, and please correct me if I'm wrong, that when I embed the HTML5 version of the videos, it doesn't play ads on top.

Not sure if this will ever change. They're probably just trying to work out the best way to show ads on the HTML5 player.

I have just faced the same problem. First, you need to install the appropriate Oracle client for your OS. In my case, to install it on Ubuntu x64 I have followed this instructions https://help.ubuntu.com/community/Oracle%20Instant%20Client#Install_RPMs

Then, you need to install cx_Oracle, a Python module to connect to the Oracle client. Again, assuming you are running Ubuntu in a 64bit machine, you should type in a shell:

wget -c http://prdownloads.sourceforge.net/cx-oracle/cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm
sudo alien -i cx_Oracle-5.0.4-11g-unicode-py27-1.x86_64.rpm

This will work for Oracle 11g if you have installed Python 2.7.x, but you can download a different cx_Oracle version in http://cx-oracle.sourceforge.net/ To check which Python version do you have, type in a terminal:

python -V

I hope it helps

In my case:

sudo -E add-apt-repository ppa:linuxuprising/java

sudo apt-get update

sudo apt install  oracle-java12-installer

that works fine

I had to be sure to change these settings in both the Target and Project settings on xCode 4.3.2 after doing that and setting it to build for both armv6 and armv7 everywhere I was able to submit my app.

For safe measure I also exited xCode between making the changes and doing a clean, build, archive cycle.

Try replacing this

var query = context.Search(id, searchText);

with

var query = context.Search(id, searchText).tolist();

and everything will work well.

There is no need to set the delimiter by breaking it up in pieces like you have done.

Here is a complete program you can compile and run:

import java.util.Arrays;
public class SplitExample {
    public static final String PLAYER = "1||1||Abdul-Jabbar||Karim||1996||1974";
    public static void main(String[] args) {
        String[] data = PLAYER.split("\\|\\|");
        System.out.println(Arrays.toString(data));
    }
}

If you want to use split with a pattern, you can use Pattern.compile or Pattern.quote.

To see compile and quote in action, here is an example using all three approaches:

import java.util.Arrays;
import java.util.regex.Pattern;
public class SplitExample {
    public static final String PLAYER = "1||1||Abdul-Jabbar||Karim||1996||1974";
    public static void main(String[] args) {
        String[] data = PLAYER.split("\\|\\|");
        System.out.println(Arrays.toString(data));

        Pattern pattern = Pattern.compile("\\|\\|");
        data = pattern.split(PLAYER);
        System.out.println(Arrays.toString(data));

        pattern = Pattern.compile(Pattern.quote("||"));
        data = pattern.split(PLAYER);
        System.out.println(Arrays.toString(data));
    }
}

The use of patterns is recommended if you are going to split often using the same pattern. BTW the output is:

[1, 1, Abdul-Jabbar, Karim, 1996, 1974]
[1, 1, Abdul-Jabbar, Karim, 1996, 1974]
[1, 1, Abdul-Jabbar, Karim, 1996, 1974]

This is a faster version of the code from the post marked as the answer.

All of the benchmarks that I have performed show that a simple for loop that only contains something like an array fill is typically twice as fast if it is decrementing versus if it is incrementing.

Also, the array Length property is already passed as the parameter so it doesn't need to be retrieved from the array properties. It should also be pre-calculated and assigned to a local variable. Loop bounds calculations that involve a property accessor will re-compute the value of the bounds before each iteration of the loop.

public static byte[] CreateSpecialByteArray(int length)
{
    byte[] array = new byte[length];

    int len = length - 1;

    for (int i = len; i >= 0; i--)
    {
        array[i] = 0x20;
    }

    return array;
}

I wouldn't access state in the Action Creator. I would use mapStateToProps() and import the entire state object and import a combinedReducer file (or import * from './reducers';) in the component the Action Creator is eventually going to. Then use destructuring in the component to use whatever you need from the state prop. If the Action Creator is passing the state onto a Reducer for the given TYPE, you don't need to mention state because the reducer has access to everything that is currently set in state. Your example is not updating anything. I would only use the Action Creator to pass along state from its parameters.

In the reducer do something like:

const state = this.state;
const apple = this.state.apples;

If you need to perform an action on state for the TYPE you are referencing, please do it in the reducer.

Please correct me if I'm wrong!!!

• REST stands for representational state transfer whereas SOAP stands for Simple Object Access Protocol.

• SOAP defines its own security where as REST inherits security from the underlying transport.

• SOAP does not support error handling, but REST has built-in error handling.

• REST is lightweight and does not require XML parsing. REST can be consumed by any client, even a web browser with Ajax and JavaScript. REST consumes less bandwidth, it does not require a SOAP header for every message.

  • REST is useful over any protocol which provide a URI. Ignore point 5 for REST as mentioned below in the picture.

Add "target": "ESNEXT" property to the tsconfig.json file.

{
    "compilerOptions": {
        "target": "ESNEXT" /* Specify ECMAScript target version: 'ES3' (default), 'ES5', 'ES2015', 'ES2016', 'ES2017', or 'ESNEXT'. */
    }
}

Postman doesn't do that but you can run multiple curl requests asynchronously in Bash:

curl url1 & curl url2 & curl url3 & ...

Remember to add an & after each request which means that request should run as an async job.

Postman however can generate curl snippet for your request: https://learning.getpostman.com/docs/postman/sending_api_requests/generate_code_snippets/

primes = {x for x in range(2, 101) if all(x%y for y in range(2, min(x, 11)))}

I simplified the test a bit - if all(x%y instead of if not any(not x%y

I also limited y's range; there is no point in testing for divisors > sqrt(x). So max(x) == 100 implies max(y) == 10. For x <= 10, y must also be < x.

pairs = {(x, x+2) for x in primes if x+2 in primes}

Instead of generating pairs of primes and testing them, get one and see if the corresponding higher prime exists.

Here is the solution I used for me Is works for fetching JSON from string

protected String getJSONFromString(String stringJSONArray) throws JSONException {
        return new StringBuffer(
               new JSONArray(stringJSONArray).getJSONObject(0).getString("cartype"))
                   .append(" ")
                   .append(
               new JSONArray(employeeID).getJSONObject(0).getString("model"))
              .toString();
    }

I'd use RestSharp - https://github.com/restsharp/RestSharp

Create class to deserialize to:

public class MyObject {
    public string Id { get; set; }
    public string Text { get; set; }
    ...
}

And the code to get that object:

RestClient client = new RestClient("http://whatever.com");
RestRequest request = new RestRequest("path/to/object");
request.AddParameter("id", "123");

// The above code will make a request URL of 
// "http://whatever.com/path/to/object?id=123"
// You can pick and choose what you need

var response = client.Execute<MyObject>(request);

MyObject obj = response.Data;

Check out http://restsharp.org/ to get started.

The best solution probably is to name things instead of returning meaningless tuples (unless there is some logic behind the order of the returned items). You can for example use a dictionary:

def func():
    return {'lat': 1, 'lng': 2}
    
latitude = func()['lat']

You could even use namedtuple if you want to add extra information about what you are returning (it's not just a dictionary, it's a pair of coordinates):

from collections import namedtuple 

Coordinates = namedtuple('Coordinates', ['lat', 'lng'])

def func():
    return Coordinates(lat=1, lng=2)

latitude = func().lat

If the objects within your dictionary/tuple are strongly tied together then it may be a good idea to even define a class for it. That way you'll also be able to define more complex operations. A natural question that follows is: When should I be using classes in Python?

Most recent versions of python (= 3.7) have dataclasses which you can use to define classes with very few lines of code:

from dataclasses import dataclass

@dataclass
class Coordinates:
    lat: float = 0
    lng: float = 0

def func():
    return Coordinates(lat=1, lng=2)

latitude = func().lat

The primary advantage of dataclasses over namedtuple is that its easier to extend, but there are other differences. Note that by default, dataclasses are mutable, but you can use @dataclass(frozen=True) instead of @dataclass to force them being immutable.

Similar to answer by @Jeff_Alieffson, but not relying on default Locale:

Use DecimalFormatSymbols for explicit locale:

DecimalFormatSymbols decimalFormatSymbols  = DecimalFormatSymbols.getInstance(new Locale("ru", "RU"));

Or explicit separator symbols:

DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
decimalFormatSymbols.setDecimalSeparator('.');
decimalFormatSymbols.setGroupingSeparator(' ');

Then:

new DecimalFormat("#,##0.00", decimalFormatSymbols).format(new BigDecimal("12345"));

Result:

12 345.00

If I understand you correctly, you need to use -SearchBase:

Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *

Note that Get-ADUser defaults to using

 -SearchScope Subtree

so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).

I meet this problem when I try to use mingw to compile the xgboost lib in Win10. Finally I found the solution.

Create a file named as .bashrc in your home directory (usually the C:\Users\username). Then add the path to it. Remember to use quotes if your path contains blank, and remember to use /c/ instead of C:/

For example:

PATH=$PATH:"/c/Program Files/mingw-w64/x86_64-7.2.0-posix-seh-rt_v5-rev1/mingw64/bin"

The main difference with shell config files is that some are only read by "login" shells (eg. when you login from another host, or login at the text console of a local unix machine). these are the ones called, say, .login or .profile or .zlogin (depending on which shell you're using).

Then you have config files that are read by "interactive" shells (as in, ones connected to a terminal (or pseudo-terminal in the case of, say, a terminal emulator running under a windowing system). these are the ones with names like .bashrc, .tcshrc, .zshrc, etc.

bash complicates this in that .bashrc is only read by a shell that's both interactive and non-login, so you'll find most people end up telling their .bash_profile to also read .bashrc with something like

[[ -r ~/.bashrc ]] && . ~/.bashrc

Other shells behave differently - eg with zsh, .zshrc is always read for an interactive shell, whether it's a login one or not.

The manual page for bash explains the circumstances under which each file is read. Yes, behaviour is generally consistent between machines.

.profile is simply the login script filename originally used by /bin/sh. bash, being generally backwards-compatible with /bin/sh, will read .profile if one exists.

Instead of adding the line breaks with nl2br() and then removing the line breaks with explode(), try using the line break character '\r' or '\n' or '\r\n'.

<?php     $options= file_get_contents("employees.txt");     $options=explode("\n",$options);        // try \r as well.      foreach ($options as $singleOption){         echo "<option value='".$singleOption."'>".$singleOption."</option>";     }   ?> 

This could also fix the issue if the problem was due to Google Spreadsheets reading the line breaks.

What levi said about passing it into the constructor is correct, but you could also use an object.

I think what Veverke is trying to say is that you could easily use the delete keyword on an object to achieve the same effect.

I think you're confused by the terminology; properties are components of the object that you can use as named indices (if you want to think of it that way).

Try something like this:

var obj = {
    "bob": "dole",
    "mr.": "peabody",
    "darkwing": "duck"
};

Then, you could just do this:

delete obj["bob"];

The structure of the object would then be this:

{
    "mr.": "peabody",
    "darkwing": "duck"
}

Which has the same effect.

In general you can use Object class for any type, but you have do type casting later!

eg:-

Object object = 12;
    Object object1 = "Aditya";
    Object object2 = 12.12;

    System.out.println(Integer.parseInt(object.toString()) + 2);

    System.out.println(object1.toString() + " Kumar");
    System.out.println(Double.parseDouble(object2.toString()) + 2.12);

You can do it programmatically using setBackgroundResource:

editText.setBackgroundResource(android.R.color.transparent);

Got the issue when trying Xcode 9 beta and going back to Xcode 8. A simple Clean on the target resolved the issue.

Try this on your context:

public class MyDatabase : DbContext
{
    public MyDatabase ()
        : base(ContextHelper.CreateConnection("Connection string"), true)
    {
        ((IObjectContextAdapter)this).ObjectContext.CommandTimeout = 180; // seconds
    }
}

If you want to define the timeout in the connection string, use the Connection Timeout parameter like in the following connection string:

<connectionStrings>

<add name="AdventureWorksEntities"
connectionString="metadata=.\AdventureWorks.csdl|.\AdventureWorks.ssdl|.\AdventureWorks.msl;
provider=System.Data.SqlClient;provider connection string='Data Source=localhost;
Initial Catalog=AdventureWorks;Integrated Security=True;Connection Timeout=60;
multipleactiveresultsets=true'" providerName="System.Data.EntityClient" />

</connectionStrings>

whats actually wrong with:

input { border: 1px solid #f00; }

do you only want it on inputs with errors? in that case give the input a class of error...

input.error { border: 1px solid #f00; }

The Dir function is the way to go, but the problem is that you cannot use the Dir function recursively, as stated here, towards the bottom.

The way that I've handled this is to use the Dir function to get all of the sub-folders for the target folder and load them into an array, then pass the array into a function that recurses.

Here's a class that I wrote that accomplishes this, it includes the ability to search for filters. (You'll have to forgive the Hungarian Notation, this was written when it was all the rage.)

Private m_asFilters() As String
Private m_asFiles As Variant
Private m_lNext As Long

Public Function GetFileList(ByVal ParentDir As String, Optional ByVal sSearch As String, Optional ByVal Deep As Boolean = True) As Variant
    m_lNext = 0
    m_lMax = 0

    ReDim m_asFiles(0)
    If Len(sSearch) Then
        m_asFilters() = Split(sSearch, "|")
    Else
        ReDim m_asFilters(0)
    End If

    If Deep Then
        Call RecursiveAddFiles(ParentDir)
    Else
        Call AddFiles(ParentDir)
    End If

    If m_lNext Then
        ReDim Preserve m_asFiles(m_lNext - 1)
        GetFileList = m_asFiles
    End If

End Function

                End If
                m_asFiles(m_lNext) = ParentDir & sFile
                m_lNext = m_lNext + 1
            End If
            sFile = Dir
        Loop
    Next l
End Sub

RecordCount is what you want to use.

If Not temp_rst1.RecordCount > 0 ...

Forget switch and break, lets play with if. And instead of asserting

if(pageid === "listing-page" || pageid === "home-page")

lets create several arrays with cases and check it with Array.prototype.includes()

var caseA = ["listing-page", "home-page"];
var caseB = ["details-page", "case04", "case05"];

if(caseA.includes(pageid)) {
    alert("hello");
}
else if (caseB.includes(pageid)) {
    alert("goodbye");
}
else {
    alert("there is no else case");
}

Examining the cookies the site gives can reveal the underlying framework. CodeIgniter, for example defaults to a telltale ci_sessions cookie. Sites using PEAR Auth will do something similar.

in parent.html:

<script type="text/javascript">
    $(document).ready(function () {
        var output = "data";
        var OpenWindow = window.open("child.html", "mywin", '');
        OpenWindow.dataFromParent = output; // dataFromParent is a variable in child.html
        OpenWindow.init();
    });
</script>

in child.html:

<script type="text/javascript">
    var dataFromParent;    
    function init() {
        document.write(dataFromParent);
    }
</script>

I'm surprised no one has mentioned Sybase PowerBuilder

• Confusing syntax
• Confusing object model
• Lack of native regular expression support
• Difficult to use IDE (esp the tool palette)

If anyone is using WordPress, you can use something like:

if (jQuery('.dropdown-menu li').hasClass('active')) {
    jQuery('.current-menu-parent').addClass('current-menu-item');
}

I'd agree it is interesting to propose a particular style of working. However, unless I have the chance to set the style, I usually follow what's been done for consistency.

Taking a look at the Linux Kernel Commits, the project that started git if you like, http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=bca476139d2ded86be146dae09b06e22548b67f3, they don't follow the 50/72 rule. The first line is 54 characters.

I would say consistency matters. Set up proper means of identifying users who've made commits (user.name, user.email - especially on internal networks. User@OFFICE-1-PC-10293982811111 isn't a useful contact address). Depending on the project, make the appropriate detail available in the commit. It's hard to say what that should be; it might be tasks completed in a development process, then details of what's changed.

I don't believe users should use git one way because certain interfaces to git treat the commits in certain ways.

I should also note there are other ways to find commits. For a start, git diff will tell you what's changed. You can also do things like git log --pretty=format:'%T %cN %ce' to format the options of git log.

To use the best of both worlds, the expressivity and conciseness of HQL and the dynamic nature of Criteria consider using Querydsl.

Querydsl supports JPA/Hibernate, JDO, SQL and Collections.

I am the maintainer of Querydsl, so this answer is biased.

SELECT  dateadd(dd,DAYS,'2013-09-07 00:00:00') DATES

I would question the problem statement rather than just accept it blindly. You only need timeouts from the console or over the network. If the latter you have Socket.setSoTimeout() and HttpURLConnection.setReadTimeout() which both do exactly what is required, as long as you set them up correctly when you construct/acquire them. Leaving it to an arbitrary point later in the application when all you have is the InputStream is poor design leading to a very awkward implementation.

For Asp.Net MVC

@Html.ListBox("parameterName", ViewBag.ParameterValueList as MultiSelectList, 
 new { 
 @class = "chosen-select form-control"
 }) 

or

  @Html.ListBoxFor(model => model.parameterName,
  ViewBag.ParameterValueList as MultiSelectList,
   new{
       data_placeholder = "Select Options ",
       @class = "chosen-select form-control"
   })

Try this code it works:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim CustomeDate As String = ("#" & DOE.Value.Date.ToString("d/MM/yyyy") & "#")
    MsgBox(CustomeDate.ToString)

    con.Open()

    dadap = New System.Data.OleDb.OleDbDataAdapter("SELECT * FROM QRY_Tran where FORMAT(qry_tran.doe,'d/mm/yyyy') = " & CustomeDate & "", con)

    ds = New System.Data.DataSet
    dadap.Fill(ds)
    Dgview.DataSource = ds.Tables(0)
    con.Close()

Note : if u use dd for date representation it will return nothing while selecting 1 to 9 so use d for selection

'Date time format
'MMM     Three-letter month.
'ddd     Three-letter day of the week.
'd       Day of the month.
'HH      Two-digit hours on 24-hour scale.
'mm      Two-digit minutes.
'yyyy    Four-digit year.

The documentation contains a full list of the date formats.

I prefer to concatenate multiple Strings together. This works either for echo AND for variables. Also some IDEs auto-initialize new lines if you hit enter. This Syntax also generate small output because there are much less whitespaces in the strings.

echo ''
    .'one {'
    .'    color: red;'
    .'}'
    ;

$foo = ''
    .'<h1>' . $bar . '</h1>'  // insert value of bar
    .$bar                     // insert value of bar again
    ."<p>$bar</p>"            // and again
    ."<p>You can also use Double-Quoted \t Strings for single lines. \n To use Escape Sequences.</p>"
    // also you can insert comments in middle, which aren't in the string.
    .'<p>Or to insert Escape Sequences in middle '."\n".' of a string</p>'
    ;

Normally i start with an empty string and then append bit by bit to it:

$foo = '';

$foo .= 'function sayHello()'
    .'    alert( "Hello" );'
    ."}\n";

$foo .= 'function sum( a , b )'
    .'{'
    .'    return a + b ;'
    ."}\n";

(Please stop Posts like "uh. You answer to an five jears old Question." Why not? There are much people searching for an answer. And what's wrong to use five year old ideas? If they don't find "their" solution they would open a new Question. Then the first five answers are only "use the search function before you ask!" So. I give you another solution to solve problems like this.)

"Headers already sent" means that your PHP script already sent the HTTP headers, and as such it can't make modifications to them now.

Check that you don't send ANY content before calling session_start. Better yet, just make session_start the first thing you do in your PHP file (so put it at the absolute beginning, before all HTML etc).

You can use cv2.FONT_HERSHEY_SIMPLEX instead of cv2.CV_FONT_HERSHEY_SIMPLEX in current opencv version

hyperjaxb (versions 2 and 3) actually generates hibernate mapping files and related entity objects and also does a round trip test for a given XSD and sample XML file. You can capture the log output and see the DDL statements for yourself. I had to tweak them a little bit, but it gives you a basic blue print to start with.

If user enters 34abc and you pass them to atoi it will return 34. If you want to validate the value entered then you have to use isdigit on the entered string iteratively

Here's a rotation generator which doesn't need to make a warped copy of the input sequence ... may be useful if the input sequence is much larger than 7 items.

>>> def rotated_sequence(seq, start_index):
...     n = len(seq)
...     for i in xrange(n):
...         yield seq[(i + start_index) % n]
...
>>> s = 'su m tu w th f sa'.split()
>>> list(rotated_sequence(s, s.index('m')))
['m', 'tu', 'w', 'th', 'f', 'sa', 'su']
>>>

Another way to identify the correct SDK is to install Android Studio, create a new project, go to project structure, SDK Location and find where the SDK was installed.

I found using the default installation process on a mac that the SDK home folder was in the /Users/'yourUser'/Library/Android/sdk folder. Make sure you have enabled your Mac to view the Library folder.

The problem is that you don't have the administrator rights to access it as running or compilation of something is being done in the basic C drive. To eliminate this problem, run the devcpp.exe as an administrator. You could also change the permission from properties and allowing access read write modify etc for the system and by the system.

There is a shorter alternative to the previous answer. SVG Elements can also be grouped by nesting svg elements:

<svg xmlns="http://www.w3.org/2000/svg"
  xmlns:xlink="http://www.w3.org/1999/xlink">
  <svg x="10">
    <rect x="10" y="10" height="100" width="100" style="stroke:#ff0000;fill: #0000ff"/>
  </svg>
  <svg x="200">
    <rect x="10" y="10" height="100" width="100" style="stroke:#009900;fill: #00cc00"/>
  </svg>
</svg>

The two rectangles are identical (apart from the colors), but the parent svg elements have different x values.

See http://tutorials.jenkov.com/svg/svg-element.html.

$animals = array('--Select Animal--', 'Cat', 'Dog', 'Cow');
$selected_key = $_POST['animal'];
$selected_val = $animals[$_POST['animal']];

Use your $animals list to generate your dropdown list; you now can get the key & the value of that key.

The line

Object EchoServer0;

says that you are allocating an Object named EchoServer0. This has nothing to do with the class EchoServer0. Furthermore, the object is not initialized, so EchoServer0 is null. Classes and identifiers have separate namespaces. This will actually compile:

String String = "abc";  // My use of String String was deliberate.

Please keep to the Java naming standards: classes begin with a capital letter, identifiers begin with a small letter, constants and enums are all-capitals.

public final String ME = "Eric Jablow";
public final double GAMMA = 0.5772;
public enum Color { RED, ORANGE, YELLOW, GREEN, BLUE, INDIGO, VIOLET}
public COLOR background = Color.RED;

Your conversion data is response[25] and follow the below steps.

var i = parseFloat(response[25]).toFixed(2)
console.log(i)//-6527.34

A general answer involves using a Manager object. Adapted from the docs:

from multiprocessing import Process, Manager

def f(d):
    d[1] += '1'
    d['2'] += 2

if __name__ == '__main__':
    manager = Manager()

    d = manager.dict()
    d[1] = '1'
    d['2'] = 2

    p1 = Process(target=f, args=(d,))
    p2 = Process(target=f, args=(d,))
    p1.start()
    p2.start()
    p1.join()
    p2.join()

    print d

Output:

$ python mul.py 
{1: '111', '2': 6}

Make it Generic Swift 4

struct Matrix<T> {
    let rows: Int, columns: Int
    var grid: [T]
    init(rows: Int, columns: Int,defaultValue: T) {
        self.rows = rows
        self.columns = columns
        grid = Array(repeating: defaultValue, count: rows * columns) as! [T]
    }
    func indexIsValid(row: Int, column: Int) -> Bool {
        return row >= 0 && row < rows && column >= 0 && column < columns
    }
    subscript(row: Int, column: Int) -> T {
        get {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            return grid[(row * columns) + column]
        }
        set {
            assert(indexIsValid(row: row, column: column), "Index out of range")
            grid[(row * columns) + column] = newValue
        }
    }
}


var matrix:Matrix<Bool> = Matrix(rows: 1000, columns: 1000,defaultValue:false)

matrix[0,10] = true


print(matrix[0,10])

It could have something to do with your styles. In my case, I am using a link within the parent "item" div, so I had to change my stylesheet to say the following:

.carousel .item a > img {
  display: block;
  line-height: 1;
}

under the preexisting boostrap code:

.carousel .item > img {
  display: block;
  line-height: 1;
}

and my image looks like:

<div class="active item" id="2"><a href="http://epdining.com/eats.php?place=TestRestaurant1"><img src="rimages/2.jpg"></a><div class="carousel-caption"><p>This restaurant is featured blah blah blah blah blah.</p></div></div>

diplay: flex; for it's container and margin:auto; for it's item works perfect.

NOTE: You have to setup the width and height to see the effect.

#container{_x000D_
  width: 100%; /*width needs to be setup*/_x000D_
  height: 150px; /*height needs to be setup*/_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.item{_x000D_
  margin: auto; /*These will make the item in center*/_x000D_
  background-color: #CCC;_x000D_
}

<div id="container">_x000D_
   <div class="item">CENTER</div>_x000D_
</div>

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

IntelliJ IDEA and Android Studio have plugins for this:

• ? Android Parcelable code generator (Apache License 2.0)
• Auto Parcel (The MIT License)
• SerializableParcelable Generator (The MIT License)
• Parcelable Code Generator (for Kotlin) (Apache License 2.0)

These plugins generate Android Parcelable boilerplate code based on fields in the class.

You should declare a class Compare and overload operator() for it like this:

class Foo
{

};

class Compare
{
public:
    bool operator() (Foo, Foo)
    {
        return true;
    }
};

int main()
{
    std::priority_queue<Foo, std::vector<Foo>, Compare> pq;
    return 0;
}

Or, if you for some reasons can't make it as class, you could use std::function for it:

class Foo
{

};

bool Compare(Foo, Foo)
{
    return true;
}

int main()
{
    std::priority_queue<Foo, std::vector<Foo>, std::function<bool(Foo, Foo)>> pq(Compare);
    return 0;
}

I would use regular expression matching to sum over variables with certain pattern names. For example:

df <- df %>% mutate(sum1 = rowSums(.[grep("x[3-5]", names(.))], na.rm = TRUE),
                    sum_all = rowSums(.[grep("x", names(.))], na.rm = TRUE))

This way you can create more than one variable as a sum of certain group of variables of your data frame.

The script element that loads the API is missing the required authentication parameter. If you are using the standard Maps JavaScript API, you must use a key parameter with a valid API key. If you are a Premium Plan customer, you must use either a client parameter with your client ID or a key parameter with a valid API key.

See the guide to API keys and client IDs.

Executing a click via JavaScript has some behaviors of which you should be aware. If for example, the code bound to the onclick event of your element invokes window.alert(), you may find your Selenium code hanging, depending on the implementation of the browser driver. That said, you can use the JavascriptExecutor class to do this. My solution differs from others proposed, however, in that you can still use the WebDriver methods for locating the elements.

// Assume driver is a valid WebDriver instance that
// has been properly instantiated elsewhere.
WebElement element = driver.findElement(By.id("gbqfd"));
JavascriptExecutor executor = (JavascriptExecutor)driver;
executor.executeScript("arguments[0].click();", element);

You should also note that you might be better off using the click() method of the WebElement interface, but disabling native events before instantiating your driver. This would accomplish the same goal (with the same potential limitations), but not force you to write and maintain your own JavaScript.

I assume by "didn't work" you mean that it's giving you a timestamp instead of the formatted date, because you were doing it correctly:

$effectiveDate = strtotime("+3 months", strtotime($effectiveDate)); // returns timestamp
echo date('Y-m-d',$effectiveDate); // formatted version

in short, We can use rm -r -fo {folderName} to remove the folder recursively (remove all the files and folders inside) and force

Presumably this would work:

IF(compliment = 'set' OR compliment = 'Y' OR compliment = 1, 'Y', 'N') AS customer_compliment

Using the so called f strings:

answer = True
myvar = f"the answer is {answer}"

Then if I do

print(myvar)

I will get:

the answer is True

I like f strings because one does not have to worry about the order in which the variables will appear in the printed text, which helps in case one has multiple variables to be printed as strings.

It changes in angular 2.1.0

In something.module.ts

import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { BlogComponent } from './blog.component';
import { AddComponent } from './add/add.component';
import { EditComponent } from './edit/edit.component';
import { RouterModule } from '@angular/router';
import { MaterialModule } from '@angular/material';
import { FormsModule } from '@angular/forms';
const routes = [
  {
    path: '',
    component: BlogComponent
  },
  {
    path: 'add',
    component: AddComponent
  },
  {
    path: 'edit/:id',
    component: EditComponent,
    data: {
      type: 'edit'
    }
  }

];
@NgModule({
  imports: [
    CommonModule,
    RouterModule.forChild(routes),
    MaterialModule.forRoot(),
    FormsModule
  ],
  declarations: [BlogComponent, EditComponent, AddComponent]
})
export class BlogModule { }

To get the data or params in edit component

import { Component, OnInit } from '@angular/core';
import { Router, ActivatedRoute, Params, Data } from '@angular/router';
@Component({
  selector: 'app-edit',
  templateUrl: './edit.component.html',
  styleUrls: ['./edit.component.css']
})
export class EditComponent implements OnInit {
  constructor(
    private route: ActivatedRoute,
    private router: Router

  ) { }
  ngOnInit() {

    this.route.snapshot.params['id'];
    this.route.snapshot.data['type'];

  }
}

Google Maps actually uses signed values to represent the position:

• Latitude : max/min 90.0000000 to -90.0000000

• Longitude : max/min 180.0000000 to -180.0000000

So if you want to work with Coordinates in your projects you would need DECIMAL(10,7) ie. for SQL.

No, not all browsers support the sizes attribute:

• Safari: Yes, it picks the picture that fits best.
• Opera: Yes, it picks the picture that fits best.
• IE11: Not sure. It apparently takes the larger picture it finds, which is a bit crude but okay.
• Chrome: No, see bugs 112941 and 324820. In fact, Chrome tends to load all declared icons, not only the best/first/last one.
• Firefox: No, see bug 751712. Like Chrome, Firefox tends to load all declared icon.

Note that some platforms define specific sizes:

• Android Chrome expects a 192x192 icon, but it favors the icons declared in manifest.json if it is present. Plus, Chrome uses the Apple Touch icon for bookmarks.
• Coast by Opera expects a 228x228 icon.
• Google TV expects a 96x96 icon.

Do you want iteration? itertools.combinations. Common usage:

>>> import itertools
>>> itertools.combinations('abcd',2)
<itertools.combinations object at 0x01348F30>
>>> list(itertools.combinations('abcd',2))
[('a', 'b'), ('a', 'c'), ('a', 'd'), ('b', 'c'), ('b', 'd'), ('c', 'd')]
>>> [''.join(x) for x in itertools.combinations('abcd',2)]
['ab', 'ac', 'ad', 'bc', 'bd', 'cd']

If you just need to compute the formula, use math.factorial:

import math

def nCr(n,r):
    f = math.factorial
    return f(n) / f(r) / f(n-r)

if __name__ == '__main__':
    print nCr(4,2)

In Python 3, use the integer division // instead of / to avoid overflows:

return f(n) // f(r) // f(n-r)

Output

6

    $url ="https://yourFile.pdf";
    $content = file_get_contents($url);

    header('Content-Type: application/pdf');
    header('Content-Length: ' . strlen($content));
    header('Content-Disposition: inline; filename="YourFileName.pdf"');
    header('Cache-Control: private, max-age=0, must-revalidate');
    header('Pragma: public');
    ini_set('zlib.output_compression','0');

    die($content);

Tested and works fine. If you want the file to download instead, replace

    Content-Disposition: inline

with

    Content-Disposition: attachment

Determine if property is existing (but is not a falsy value):

if (typeof query !== 'undefined' && query !== null){
   doStuff();
}

Usually using

if (query){
   doStuff();
}

is sufficient. Please note that:

if (!query){
   doStuff();
}

doStuff() will execute even if query was an existing variable with falsy value (0, false, undefined or null)

Btw, there's a sexy coffeescript way of doing this:

if object?.property? then doStuff()

which compiles to:

if ((typeof object !== "undefined" && object !== null ? object.property : void 0) != null) 

{
  doStuff();
}

Your quotes are in the wrong spot. Here's a simple example:

<div style={{backgroundColor: "#FF0000"}}>red</div>

You can make a symbolic link of your module to the standard path, so depmod will see it and you'll be able load it as any other module.

sudo ln -s /path/to/module.ko /lib/modules/`uname -r`
sudo depmod -a
sudo modprobe module

If you add the module name to /etc/modules it will be loaded any time you boot.

Anyway I think that the proper configuration is to copy the module to the standard paths.

Both of them behave differently when it comes to dynamic data handling.

If the variable is empty ( '' ) the null coalescing will treat the variable as true but the shorthand ternary operator won't. And that's something to have in mind.

$a = NULL;
$c = '';

print $a ?? '1b';
print "\n";

print $a ?: '2b';
print "\n";

print $c ?? '1d';
print "\n";

print $c ?: '2d';
print "\n";

print $e ?? '1f';
print "\n";

print $e ?: '2f';

And the output:

1b
2b

2d
1f

Notice: Undefined variable: e in /in/ZBAa1 on line 21
2f

The solution that work for me is the following

$("#element").addEventListener("keyup", function(event) {
    if (event.key === "Enter") {
        // do something
    }
});

A bit late but hopefully useful.

Why not try some of the third party tools that can be integrated into SSMS.

I’ve worked with ApexSQL Search (100% free) with good success for both schema and data search and there is also SSMS tools pack that has this feature (not free for SQL 2012 but quite affordable).

Stored procedure above is really great; it’s just that this is way more convenient in my opinion. Also, it would require some slight modifications if you want to search for datetime columns or GUID columns and such…

I had the same problem and used Glide library instead. Cache is out of the box there. https://github.com/bumptech/glide

The algorithm you are using, "AES", is a shorthand for "AES/ECB/NoPadding". What this means is that you are using the AES algorithm with 128-bit key size and block size, with the ECB mode of operation and no padding.

In other words: you are only able to encrypt data in blocks of 128 bits or 16 bytes. That's why you are getting that IllegalBlockSizeException exception.

If you want to encrypt data in sizes that are not multiple of 16 bytes, you are either going to have to use some kind of padding, or a cipher-stream. For instance, you could use CBC mode (a mode of operation that effectively transforms a block cipher into a stream cipher) by specifying "AES/CBC/NoPadding" as the algorithm, or PKCS5 padding by specifying "AES/ECB/PKCS5", which will automatically add some bytes at the end of your data in a very specific format to make the size of the ciphertext multiple of 16 bytes, and in a way that the decryption algorithm will understand that it has to ignore some data.

In any case, I strongly suggest that you stop right now what you are doing and go study some very introductory material on cryptography. For instance, check Crypto I on Coursera. You should understand very well the implications of choosing one mode or another, what are their strengths and, most importantly, their weaknesses. Without this knowledge, it is very easy to build systems which are very easy to break.

Update: based on your comments on the question, don't ever encrypt passwords when storing them at a database!!!!! You should never, ever do this. You must HASH the passwords, properly salted, which is completely different from encrypting. Really, please, don't do what you are trying to do... By encrypting the passwords, they can be decrypted. What this means is that you, as the database manager and who knows the secret key, you will be able to read every password stored in your database. Either you knew this and are doing something very, very bad, or you didn't know this, and should get shocked and stop it.

There could be two ways/syntax to bind a static property. If p is a static property in class MainWindow, then binding for textbox will be:

1.

<TextBox Text="{x:Static local:MainWindow.p}" />

2.

<TextBox Text="{Binding Source={x:Static local:MainWindow.p},Mode=OneTime}" />

Try it:

is_even = lambda x: True if x % 2 == 0 else False
print(is_even(10))
print(is_even(11))

Out:

True
False

I have overcome a similar problem with a Custom JsonDeSerializer. I tried to make it a bit generic but still not enough. It is a solution though that fits my needs.

First of all you need to implement a new JsonDeserializer for Map objects.

public class MapDeserializer<T, U> implements JsonDeserializer<Map<T, U>>

And the deserialize method will look similar to this:

public Map<T, U> deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context)
        throws JsonParseException {

        if (!json.isJsonObject()) {
            return null;
        }

        JsonObject jsonObject = json.getAsJsonObject();
        Set<Entry<String, JsonElement>> jsonEntrySet = jsonObject.entrySet();
        Map<T, U> deserializedMap = new HashMap<T, U>();

        for (Entry<java.lang.String, JsonElement> entry : jsonEntrySet) {
            try {
                U value = context.deserialize(entry.getValue(), getMyType());
                deserializedMap.put((T) entry.getKey(), value);
            } catch (Exception ex) {
                logger.info("Could not deserialize map.", ex);
            }
        }

        return deserializedMap;
    }

The con with this solution, is that my Map's key is always of Type "String". However by chaning some things someone can make it generic. In addition, i need to say, that the value's class should be passed in the constructor. So the method getMyType() in my code returns the type of the Map's values, which was passed in the constructor.

You can reference this post How do I write a custom JSON deserializer for Gson? in order to learn more about custom deserializers.

If the instance is in VPC, make sure both "DNS resolution" and "DNS hostnames" is set to "yes". You can do this in the Aws console UI. HTH!

IMHO __call__ method and closures give us a natural way to create STRATEGY design pattern in Python. We define a family of algorithms, encapsulate each one, make them interchangeable and in the end we can execute a common set of steps and, for example, calculate a hash for a file.

I just had this same problem. 4 statements in SSMS instead of using the GUI and it was very fast.

• Make a new column

  alter table users add newusernum int;

• Copy values over

  update users set newusernum=usernum;

• Drop the old column

  alter table users drop column usernum;

• Rename the new column to the old column name

  EXEC sp_RENAME 'users.newusernum' , 'usernum', 'COLUMN';

Try Uri.IsWellFormedUriString():

• The string is not correctly escaped.

    http://www.example.com/path???/file name
  

• The string is an absolute Uri that represents an implicit file Uri.

    c:\\directory\filename
  

• The string is an absolute URI that is missing a slash before the path.

    file://c:/directory/filename
  

• The string contains unescaped backslashes even if they are treated as forward slashes.

    http:\\host/path/file
  

• The string represents a hierarchical absolute Uri and does not contain "://".

    www.example.com/path/file
  

• The parser for the Uri.Scheme indicates that the original string was not well-formed.

    The example depends on the scheme of the URI.
  

First, disable the php5 module:

a2dismod php5

then, enable the php7 module:

a2enmod php7.0

Next, reload/restart the Apache service:

service apache2 restart

wrt the comment, you need to specify exact installed php-7.x version.

You can access the local webserver which is running in your host machine in two ways.

1. Approach 1 with public IP

   Use host machine public IP address to access webserver in Jenkins docker container.

2. Approach 2 with the host network

   Use "--net host" to add the Jenkins docker container on the host's network stack. Containers which are deployed on host's stack have entire access to the host interface. You can access local webserver in docker container with a private IP address of the host machine.

NETWORK ID          NAME                      DRIVER              SCOPE
b3554ea51ca3        bridge                    bridge              local
2f0d6d6fdd88        host                      host                local
b9c2a4bc23b2        none                      null                local

Start a container with the host network Eg: docker run --net host -it ubuntu and run ifconfig to list all available network IP addresses which are reachable from docker container.

Eg: I started a nginx server in my local host machine and I am able to access the nginx website URLs from Ubuntu docker container.

docker run --net host -it ubuntu

$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
a604f7af5e36        ubuntu              "/bin/bash"         22 seconds ago      Up 20 seconds                           ubuntu_server

Unfortunately, neither of answers are good for me. Surprisingly the solution is much simpler. Return from controller:

return new HttpStatusCodeResult(HttpStatusCode.BadRequest, e.Response.ReasonPhrase);

And handle it as standard HTTP error on client as you like.

Why not just convert all <button> to <span> with type="button" and then style with your normal css button classes? Just confirmed that this works in IE11.

In my case the problem was that I had called $("#divDialog").removeData(); as part of resetting my forms data within the dialog.

This resulted in me wiping out a data structure named uiDialog which meant that the dialog had to reinitialize.

I replaced .removeData() with more specific deletes and everything started working again.

In early versions of C, all structure declarations would share a common set of fields. Given:

struct x {int x_mode; int q; float x_f};
struct y {int y_mode; int q; int y_l};
struct z {int z_mode; char name[20];};

a compiler would essentially produce a table of structures' sizes (and possibly alignments), and a separate table of structures' members' names, types, and offsets. The compiler didn't keep track of which members belonged to which structures, and would allow two structures to have a member with the same name only if the type and offset matched (as with member q of struct x and struct y). If p was a pointer to any structure type, p->q would add the offset of "q" to pointer p and fetch an "int" from the resulting address.

Given the above semantics, it was possible to write a function that could perform some useful operations on multiple kinds of structure interchangeably, provided that all the fields used by the function lined up with useful fields within the structures in question. This was a useful feature, and changing C to validate members used for structure access against the types of the structures in question would have meant losing it in the absence of a means of having a structure that can contain multiple named fields at the same address. Adding "union" types to C helped fill that gap somewhat (though not, IMHO, as well as it should have been).

An essential part of unions' ability to fill that gap was the fact that a pointer to a union member could be converted into a pointer to any union containing that member, and a pointer to any union could be converted to a pointer to any member. While the C89 Standard didn't expressly say that casting a T* directly to a U* was equivalent to casting it to a pointer to any union type containing both T and U, and then casting that to U*, no defined behavior of the latter cast sequence would be affected by the union type used, and the Standard didn't specify any contrary semantics for a direct cast from T to U. Further, in cases where a function received a pointer of unknown origin, the behavior of writing an object via T*, converting the T* to a U*, and then reading the object via U* would be equivalent to writing a union via member of type T and reading as type U, which would be standard-defined in a few cases (e.g. when accessing Common Initial Sequence members) and Implementation-Defined (rather than Undefined) for the rest. While it was rare for programs to exploit the CIS guarantees with actual objects of union type, it was far more common to exploit the fact that pointers to objects of unknown origin had to behave like pointers to union members and have the behavioral guarantees associated therewith.

Here is the App Bit Web Server (PHP,MySQL,PMA)

It can run a variety of CMS like Wordpress, Joomla, Drupal, Prestashop, etc. Besides CMS can also run PHP frameworks like Code Igniter, YII, CakePHP, etc. It is the same as WAMP or LAMP or XAMPP on your computer or laptop, but this is for android devices with lighttpd instead of apache.

Php has an inbuilt JSON Serialising function.

json_encode

json_encode

Please use that if you can and don't suffer Not Invented Here syndrome.

Another approach is to first do a searchType: 'count', then and then do a normal search with size set to results.count.

The advantage here is it avoids depending on a magic number for UPPER_BOUND as suggested in this similar SO question, and avoids the extra overhead of building too large of a priority queue that Shay Banon describes here. It also lets you keep your results sorted, unlike scan.

The biggest disadvantage is that it requires two requests. Depending on your circumstance, this may be acceptable.

I know that it may be not directly answer to your question, because you said that null values have to be supported.

But I just want to note that supporting nulls in compareTo is not in line with compareTo contract described in official javadocs for Comparable:

Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerException even though e.equals(null) returns false.

So I would either throw NullPointerException explicitly or just let it be thrown first time when null argument is being dereferenced.

This is for the icon in the browser (most of the sites omit the type):

     href="http://example.com/image.png" />

or

In case you need to parse it from a file, I find the best solution to use a HashMap<String, String> to use it inside your java code for better manipultion.

Try out this code:

public HashMap<String, String> myMethodName() throws FileNotFoundException
{
    String path = "absolute path to your file";
    BufferedReader bufferedReader = new BufferedReader(new FileReader(path));

    Gson gson = new Gson();
    HashMap<String, String> json = gson.fromJson(bufferedReader, HashMap.class);
    return json;
}

I have a Mac, but luckily this should work the same way:

pip is a command-line thing. You don't run it in python.

For example, on my Mac, I just say:

$pip install somelib

pretty easy!

if you have string array list , then convert to Int

let arrayList = list.map { Int($0)!} 
     arrayList.description

it will give you string value

Use malloc() when you don't know the amount of memory needed during compile time. In case if you have read-only strings then you can use const char* str = "something"; . Note that the string is most probably be stored in a read-only memory location and you'll not be able to modify it. On the other hand if you know the string during compiler time then you can do something like: char str[10]; strcpy(str, "Something"); Here the memory is allocated from stack and you will be able to modify the str. Third case is allocating using malloc. Lets say you don'r know the length of the string during compile time. Then you can do char* str = malloc(requiredMem); strcpy(str, "Something"); free(str);

First and foremost, a RESTful web service is STATELESS (or in other words, SESSIONLESS). Therefore, a RESTful service does not have and should not have a concept of session or cookies involved. The way to do authentication or authorization in the RESTful service is by using the HTTP Authorization header as defined in the RFC 2616 HTTP specifications. Every single request should contain the HTTP Authorization header, and the request should be sent over an HTTPs (SSL) connection. This is the correct way to do authentication and to verify the authorization of requests in a HTTP RESTful web services. I have implemented a RESTful web service for the Cisco PRIME Performance Manager application at Cisco Systems. And as part of that web service, I have implemented authentication/authorization as well.

Fixnum#to_r is not mentioned here, it was introduced since ruby 1.9. It converts Fixnum into rational form. Below are examples of its uses. This also can give exact division as long as all the numbers used are Fixnum.

 a = 1.to_r  #=> (1/1) 
 a = 10.to_r #=> (10/1) 
 a = a / 3   #=> (10/3) 
 a = a * 3   #=> (10/1) 
 a.to_f      #=> 10.0

Example where a float operated on a rational number coverts the result to float.

a = 5.to_r   #=> (5/1) 
a = a * 5.0  #=> 25.0 

I suggest you use null to represent a null value.

What is the exception you get?

BTW:

There is no year called 0 or 0000. (Though some dates allow this year)

And there is no 0 month of the year or 0 day of the month. (Which may be the cause of your problem)

Best guess:

var cur_value = $('#select-id').children('option:selected').text();

I like children better in this case because you know you're only going one branch down the DOM tree...

On Mac OS X:

sudo find / -name postgresql.conf 

You can find other conf files by the following command:

sudo find / -name pg\*.conf

Note: See usage using man:

man find

First is you have to understand the difference between MyISAM and InnoDB Engines. And this is clearly stated on this link. You can use this sql statement if you want to convert InnoDB to MyISAM:

 ALTER TABLE t1 ENGINE=MyISAM;

You have already staged the changes (presumably by running git add), so in order to get their diff, you need to run:

git diff --cached

(A plain git diff will only show unstaged changes.)

For example:

One thing i have noticed is that if the tables use different engine than the foreign key constraint does not work.

For example if one table uses:

$table->engine = 'InnoDB';

And the other uses

$table->engine = 'MyISAM';

would generate an error:

SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint

You can fix this by just adding InnoDB at the end of your table creation like so:

public function up()
{
    Schema::create('users', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->unsignedInteger('business_unit_id')->nullable();

Maybe I am missing something (lots of many-upvotes-members answers here that seem to be looking at this different to I, which would seem implausible that I am correct), but length is not the correct terminology for counting something. Length is usually used to obtain what you are getting, and not what you are wanting.

$cars.count should give you what you seem to be looking for.

As vartec says above, the HTTP spec does not define a limit, however many servers do by default. This means, practically speaking, the lower limit is 8K. For most servers, this limit applies to the sum of the request line and ALL header fields (so keep your cookies short).

• Apache 2.0, 2.2: 8K
• nginx: 4K - 8K
• IIS: varies by version, 8K - 16K
• Tomcat: varies by version, 8K - 48K (?!)

It's worth noting that nginx uses the system page size by default, which is 4K on most systems. You can check with this tiny program:

pagesize.c:

#include <unistd.h>
#include <stdio.h>

int main() {
    int pageSize = getpagesize();
    printf("Page size on your system = %i bytes\n", pageSize);
    return 0;
}

Compile with gcc -o pagesize pagesize.c then run ./pagesize. My ubuntu server from Linode dutifully informs me the answer is 4k.

SWIFT4 - Easy and elegant way of decoding JSON strings to Struct.

First step - encode String to Data with .utf8 encoding.

Than decode your Data to YourDataStruct.

struct YourDataStruct: Codable {

let type, id: String

init(_ json: String, using encoding: String.Encoding = .utf8) throws {
    guard let data = json.data(using: encoding) else {
        throw NSError(domain: "JSONDecoding", code: 0, userInfo: nil)
    }
    try self.init(data: data)
}

init(data: Data) throws {
    self = try JSONDecoder().decode(YourDataStruct.self, from: data)
}                                                                      
}

do { let successResponse = try WSDeleteDialogsResponse(response) }
} catch {}

You Can Set Variables In The Blade Templating Engine The Following Ways:

1. General PHP Block
Setting Variable: <?php $hello = "Hello World!"; ?>
Output: {{$hello}}

2. Blade PHP Block
Setting Variable: @php $hello = "Hello World!"; @endphp
Output: {{$hello}}

1. Start a graphical vim session.
2. Do :e $MYGVIMRC Enter
3. Use the graphical font selection dialog to select a font.
4. Type :set guifont= Tab Enter.
5. Type G o to start a new line at the end of the file.
6. Type Ctrl+R followed by :.

The command in step 6 will insert the contents of the : special register which contains the last ex-mode command used. Here that will be the command from step 4, which has the properly formatted font name thanks to the tab completion of the value previously set using the GUI dialog.

If you really need to do it in separate transaction you need to use REQUIRES_NEW and live with the performance overhead. Watch out for dead locks.

I'd rather do it the other way:

• Validate data on Java side.
• Run everyting in one transaction.
• If anything goes wrong on DB side -> it's a major error of DB or validation design. Rollback everything and throw critical top level error.
• Write good unit tests.

I tried all of those above answers, and I then summarized a pipeline of how to draw the fixed-axes image. It applied both to show function and savefig function.

1. before you plot:

   fig = pylab.figure()
   ax = fig.gca()
   ax.set_autoscale_on(False)
   

This is to request an ax which is subplot(1,1,1).

2. During the plot:

   ax.plot('You plot argument') # Put inside your argument, like ax.plot(x,y,label='test')
   ax.axis('The list of range') # Put in side your range [xmin,xmax,ymin,ymax], like ax.axis([-5,5,-5,200])
   

3. After the plot:

   1. To show the image :

      fig.show()
      

   2. To save the figure :

      fig.savefig('the name of your figure')
      

I find out that put axis at the front of the code won't work even though I have set autoscale_on to False.

I used this code to create a series of animation. And below is the example of combing multiple fixed axes images into an animation.

You'd have to rely on a non standard select2nd

With mysqli you're able to use multiple statements for real using mysqli_multi_query().

Read more on multiple statements in the PHP Docs.

Short answer: No.

But you might be able to do it with a bit of filthing. If you open up a test page (with GET) then evaluate some JavaScript on that page you should be able to replicate a POST request. See JavaScript post request like a form submit to see how you can replicate a POST request in JavaScript.

Hope this helps.

This should do the trick!

google.maps.event.trigger(map, "resize");
map.panTo(marker.getPosition());
map.setZoom(14);

You will need to have your maps global

Just a comment on Iker's solution.

ServletContext is a good solution for your problem. But I don't think it is good for maintains. Most of the time log files are required to be saved for long time.

Since ServletContext makes the file under the deployed file, it will be removed when server is redeployed. My suggest is to go with rootPath's parent folder instead of child one.

Although there were several great and helpful answers here, I didn't find one that seemed to be the right combination of performant, cross-platform, and robust; so I wanted to share the solution I wrote for my code:

#!/bin/bash

# array_contains "$needle" "${haystack[@]}"
#
# Returns 0 if an item ($1) is contained in an array ($@).
#
# Developer note:
#    The use of a delimiter here leaves something to be desired. The ideal
#    method seems to be to use `grep` with --line-regexp and --null-data, but
#    Mac/BSD grep doesn't support --line-regexp.
function array_contains()
{
    # Extract and remove the needle from $@.
    local needle="$1"
    shift

    # Separates strings in the array for matching. Must be extremely-unlikely
    # to appear in the input array or the needle.
    local delimiter='#!-\8/-!#'

    # Create a string with containing every (delimited) element in the array,
    # and search it for the needle with grep in fixed-string mode.
    if printf "${delimiter}%s${delimiter}" "$@" | \
        grep --fixed-strings --quiet "${delimiter}${needle}${delimiter}"; then
        return 0
    fi

    return 1
}

For me, Abhi's solution works great up to Api level 27.

But it seems that from Api level 28 and upwards, onItemSelected() is not called when listener is set, which means onItemSelected() is never called.

Therefore, I added a short if-statement to check Api level:

public void onItemSelected(AdapterView<?> parent, View arg1, int pos,long id) {

            if(Build.VERSION.SDK_INT >= 28){ //onItemSelected() doesn't seem to be called when listener is set on Api 28+
                check = 1;
            }

            if(++check > 1) {
                //Do your action here
            }
        }

I think that's quite weird and I'm not sure wether others also have this problem, but in my case it worked well.

Here is a library that does the job well https://github.com/thellimist/SwiftRandom

public extension Int {
    /// SwiftRandom extension
    public static func random(lower: Int = 0, _ upper: Int = 100) -> Int {
        return lower + Int(arc4random_uniform(UInt32(upper - lower + 1)))
    }
}

public extension Double {
    /// SwiftRandom extension
    public static func random(lower: Double = 0, _ upper: Double = 100) -> Double {
        return (Double(arc4random()) / 0xFFFFFFFF) * (upper - lower) + lower
    }
}

public extension Float {
    /// SwiftRandom extension
    public static func random(lower: Float = 0, _ upper: Float = 100) -> Float {
        return (Float(arc4random()) / 0xFFFFFFFF) * (upper - lower) + lower
    }
}

public extension CGFloat {
    /// SwiftRandom extension
    public static func random(lower: CGFloat = 0, _ upper: CGFloat = 1) -> CGFloat {
        return CGFloat(Float(arc4random()) / Float(UINT32_MAX)) * (upper - lower) + lower
    }
}

^{(Expanding on the accepted answer...)}

I needed to:

1. log views of a jpg image and an animated gif, and,
2. ensure that the images are never cached (so every view is logged), and,
3. also retain the original file extensions.

I accomplished this by creating a "secondary" .htaccess file in the sub-folder where the images are located.
The file contains only one line:

AddHandler application/x-httpd-lsphp .jpg .jpeg .gif

In the same folder, I placed the two 'original' image files (we'll call them orig.jpg and orig.gif), as well as two variations of the [simplified] script below (saved as myimage.jpg and myimage.gif)...

<?php 
  error_reporting(0); //hide errors (displaying one would break the image)

  //get user IP and the pseudo-image's URL
  if(isset($_SERVER['REMOTE_ADDR'])) {$ip =$_SERVER['REMOTE_ADDR'];}else{$ip= '(unknown)';}
  if(isset($_SERVER['REQUEST_URI'])) {$url=$_SERVER['REQUEST_URI'];}else{$url='(unknown)';}

  //log the visit
  require_once('connect.php');            //file with db connection info
  $conn = new mysqli($servername, $username, $password, $dbname);
  if (!$conn->connect_error) {         //if connected then save mySQL record
   $conn->query("INSERT INTO imageclicks (image, ip) VALUES ('$url', '$ip');");
     $conn->close();  //(datetime is auto-added to table with default of 'now')
  } 

  //display the image
  $imgfile='orig.jpg';                             // or 'orig.gif'
  header('Content-Type: image/jpeg');              // or 'image/gif'
  header('Content-Length: '.filesize($imgfile));
  header('Cache-Control: no-cache');
  readfile($imgfile);
?>

The images render (or animate) normally and can be called in any of the normal ways for images (like an <img> tag), and will save a record of the visiting IP, while invisible to the user.

UPDATE R 
SET R.status = '0' 
FROM dbo.ProductReviews AS R
INNER JOIN dbo.products AS P 
       ON R.pid = P.id 
WHERE R.id = '17190' 
  AND P.shopkeeper = '89137';

<?php
if ( session_id() != "" ) {
    session_start();
}

Basically, you need to check if a session was started before creating another one; ... more reading.

On the other hand, you chose to destroy an existing session before creating another one using session_destroy().

import os

path, dirs, files = next(os.walk("/usr/lib"))
file_count = len(files)

And to complement Rich's recursive answer, a non-recursive method.

Public Sub NonRecursiveMethod()
    Dim fso, oFolder, oSubfolder, oFile, queue As Collection

    Set fso = CreateObject("Scripting.FileSystemObject")
    Set queue = New Collection
    queue.Add fso.GetFolder("your folder path variable") 'obviously replace

    Do While queue.Count > 0
        Set oFolder = queue(1)
        queue.Remove 1 'dequeue
        '...insert any folder processing code here...
        For Each oSubfolder In oFolder.SubFolders
            queue.Add oSubfolder 'enqueue
        Next oSubfolder
        For Each oFile In oFolder.Files
            '...insert any file processing code here...
        Next oFile
    Loop

End Sub

You can use a queue for FIFO behaviour (shown above), or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach (replace Set oFolder = queue(1) with Set oFolder = queue(queue.Count) and replace queue.Remove(1) with queue.Remove(queue.Count), and probably rename the variable...)

The following MySQL statement should modify your column to accept NULLs.

ALTER TABLE `MyTable`
ALTER COLUMN `Col3` varchar(20) DEFAULT NULL

Activity:

int number = 5;
Intent i = new Intent(this, MyService.class);
i.putExtra("MyNumber", number);
startService(i);

Service:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent != null && intent.getExtras() != null){
        int number = intent.getIntExtra("MyNumber", 0);
    }
}

Based on some of the previous answers, I'm going to break my answer down into three areas.

First, physical limitations of using Action<T1, T2, T2... > vs using a derived class of EventArgs. There are three: First, if you change the number or types of parameters, every method that subscribes to will have to be changed to conform to the new pattern. If this is a public facing event that 3rd party assemblies will be using, and there is any possiblity that the event args would change, this would be a reason to use a custom class derived from event args for consistencies sake (remember, you COULD still use an Action<MyCustomClass>) Second, using Action<T1, T2, T2... > will prevent you from passing feedback BACK to the calling method unless you have a some kind of object (with a Handled property for instance) that is passed along with the Action. Third, you don't get named parameters, so if you're passing 3 bool's an int, two string's, and a DateTime, you have no idea what the meaning of those values are. As a side note, you can still have a "Fire this event safely method while still using Action<T1, T2, T2... >".

Secondly, consistency implications. If you have a large system you're already working with, it's nearly always better to follow the way the rest of the system is designed unless you have an very good reason not too. If you have publicly facing events that need to be maintained, the ability to substitute derived classes can be important. Keep that in mind.

Thirdly, real life practice, I personally find that I tend to create a lot of one off events for things like property changes that I need to interact with (Particularly when doing MVVM with view models that interact with each other) or where the event has a single parameter. Most of the time these events take on the form of public event Action<[classtype], bool> [PropertyName]Changed; or public event Action SomethingHappened;. In these cases, there are two benefits. First, I get a type for the issuing class. If MyClass declares and is the only class firing the event, I get an explicit instance of MyClass to work with in the event handler. Secondly, for simple events such as property change events, the meaning of the parameters is obvious and stated in the name of the event handler and I don't have to create a myriad of classes for these kinds of events.

I have found this helpful, but ran into some errors when adding it to a "Content=..." tag in XAML.

I had multiple lines in the content, and later found out that the content kept white spaces even though I didn't specify that. so to get around that and having it "ignore" the whitespace, I implemented such as this.

<ToolTip Width="200" Style="{StaticResource ToolTip}" 
         Content="'Text Line 1' 
                   &#x0a;&#x0d;'Text Line 2' 
                   &#x0a;&#x0d;'Text Line 3'"/>

hope this helps someone else.

(The output is has the three text lines with an empty line in between each.)

To interpret a byte sequence as a text, you have to know the corresponding character encoding:

unicode_text = bytestring.decode(character_encoding)

Example:

>>> b'\xc2\xb5'.decode('utf-8')
'µ'

ls command may produce output that can't be interpreted as text. File names on Unix may be any sequence of bytes except slash b'/' and zero b'\0':

>>> open(bytes(range(0x100)).translate(None, b'\0/'), 'w').close()

Trying to decode such byte soup using utf-8 encoding raises UnicodeDecodeError.

It can be worse. The decoding may fail silently and produce mojibake if you use a wrong incompatible encoding:

>>> '—'.encode('utf-8').decode('cp1252')
'—'

The data is corrupted but your program remains unaware that a failure has occurred.

In general, what character encoding to use is not embedded in the byte sequence itself. You have to communicate this info out-of-band. Some outcomes are more likely than others and therefore chardet module exists that can guess the character encoding. A single Python script may use multiple character encodings in different places.

ls output can be converted to a Python string using os.fsdecode() function that succeeds even for undecodable filenames (it uses sys.getfilesystemencoding() and surrogateescape error handler on Unix):

import os
import subprocess

output = os.fsdecode(subprocess.check_output('ls'))

To get the original bytes, you could use os.fsencode().

If you pass universal_newlines=True parameter then subprocess uses locale.getpreferredencoding(False) to decode bytes e.g., it can be cp1252 on Windows.

To decode the byte stream on-the-fly, io.TextIOWrapper() could be used: example.

Different commands may use different character encodings for their output e.g., dir internal command (cmd) may use cp437. To decode its output, you could pass the encoding explicitly (Python 3.6+):

output = subprocess.check_output('dir', shell=True, encoding='cp437')

The filenames may differ from os.listdir() (which uses Windows Unicode API) e.g., '\xb6' can be substituted with '\x14'—Python's cp437 codec maps b'\x14' to control character U+0014 instead of U+00B6 (¶). To support filenames with arbitrary Unicode characters, see Decode PowerShell output possibly containing non-ASCII Unicode characters into a Python string

I wasn't happy with any of these answers, and the one that's right has no explanation and negative votes so I searched around, found some stuff and edited it so that it is easy to understand. Have a play with it, not as straight forward as one would hope.

//move your variable into an Object type
Object obj=whatYouAreChecking;
System.out.println(obj);

// moving the class type into a Class variable
Class cls=obj.getClass();
System.out.println(cls);

// convert that Class Variable to a neat String
String answer = cls.getSimpleName();
System.out.println(answer);

Here is a method:

public static void checkClass (Object obj) {
    Class cls = obj.getClass();
    System.out.println("The type of the object is: " + cls.getSimpleName());       
}

That this works is not trivial at all! It's a property of the IEEE floating point representation that int°floor = ?·? if the magnitude of the numbers in question is small enough, but different representations are possible where int(floor(2.3)) might be 1.

This post explains why it works in that range.

In a double, you can represent 32bit integers without any problems. There cannot be any rounding issues. More precisely, doubles can represent all integers between and including 2⁵³ and -2⁵³.

Short explanation: A double can store up to 53 binary digits. When you require more, the number is padded with zeroes on the right.

It follows that 53 ones is the largest number that can be stored without padding. Naturally, all (integer) numbers requiring less digits can be stored accurately.

Adding one to 111(omitted)111 (53 ones) yields 100...000, (53 zeroes). As we know, we can store 53 digits, that makes the rightmost zero padding.

This is where 2⁵³ comes from.

More detail: We need to consider how IEEE-754 floating point works.

  1 bit    11 / 8     52 / 23      # bits double/single precision
[ sign |  exponent | mantissa ]

The number is then calculated as follows (excluding special cases that are irrelevant here):

-1^sign × 1.mantissa ×2^{exponent - bias}

where bias = 2^{exponent - 1} - 1, i.e. 1023 and 127 for double/single precision respectively.

Knowing that multiplying by 2^X simply shifts all bits X places to the left, it's easy to see that any integer must have all bits in the mantissa that end up right of the decimal point to zero.

Any integer except zero has the following form in binary:

1x...x where the x-es represent the bits to the right of the MSB (most significant bit).

Because we excluded zero, there will always be a MSB that is one—which is why it's not stored. To store the integer, we must bring it into the aforementioned form: -1^sign × 1.mantissa ×2^{exponent - bias}.

That's saying the same as shifting the bits over the decimal point until there's only the MSB towards the left of the MSB. All the bits right of the decimal point are then stored in the mantissa.

From this, we can see that we can store at most 52 binary digits apart from the MSB.

It follows that the highest number where all bits are explicitly stored is

111(omitted)111.   that's 53 ones (52 + implicit 1) in the case of doubles.

For this, we need to set the exponent, such that the decimal point will be shifted 52 places. If we were to increase the exponent by one, we cannot know the digit right to the left after the decimal point.

111(omitted)111x.

By convention, it's 0. Setting the entire mantissa to zero, we receive the following number:

100(omitted)00x. = 100(omitted)000.

That's a 1 followed by 53 zeroes, 52 stored and 1 added due to the exponent.

It represents 2⁵³, which marks the boundary (both negative and positive) between which we can accurately represent all integers. If we wanted to add one to 2⁵³, we would have to set the implicit zero (denoted by the x) to one, but that's impossible.

Here is what I learned: PYTHONPATH is a directory to add to the Python import search path "sys.path", which is made up of current dir. CWD, PYTHONPATH, standard and shared library, and customer library. For example:

% python3 -c "import sys;print(sys.path)"
['', 
'/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']

where the first path '' denotes the current dir., the 2nd path is via

%export PYTHONPATH=/home/username/Documents/DjangoTutorial/mySite 

which can be added to ~/.bashrc to make it permanent, and the rest are Python standard and dynamic shared library plus third-party library such as django.

As said not to mess with PYTHONHOME, even setting it to '' or 'None' will cause python3 shell to stop working:

% export PYTHONHOME=''
% python3
Fatal Python error: Py_Initialize: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'

Current thread 0x00007f18a44ff740 (most recent call first):
Aborted (core dumped)

Note that if you start a Python script, the CWD will be the script's directory. For example:

username@bud:~/Documents/DjangoTutorial% python3 mySite/manage.py runserver
==== Printing sys.path ====
/home/username/Documents/DjangoTutorial/mySite # CWD is where manage.py resides
/usr/lib/python3.6
/usr/lib/python3.6/lib-dynload
/usr/local/lib/python3.6/dist-packages
/usr/lib/python3/dist-packages

You can also append a path to sys.path at run-time: Suppose you have a file Fibonacci.py in ~/Documents/Python directory:

username@bud:~/Documents/DjangoTutorial% python3 
>>> sys.path.append("/home/username/Documents")
>>> print(sys.path)
['', '/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages', 
'/home/username/Documents']
>>> from Python import Fibonacci as fibo

or via

% PYTHONPATH=/home/username/Documents:$PYTHONPATH
% python3
>>> print(sys.path)
['', 
'/home/username/Documents', '/home/username/Documents/DjangoTutorial/mySite', 
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload', 
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']
>>> from Python import Fibonacci as fibo

Java provides a default constructor which takes no arguments and performs no special actions or initializations, when no explicit constructors are provided.

The only action taken by the implicit default constructor is to call the superclass constructor using the super() call. Constructor arguments provide you with a way to provide parameters for the initialization of an object.

Below is an example of a cube class containing 2 constructors. (one default and one parameterized constructor).

public class Cube1 {
    int length;
    int breadth;
    int height;
    public int getVolume() {
        return (length * breadth * height);
    }

    Cube1() {
        length = 10;
        breadth = 10;
        height = 10;
    }

    Cube1(int l, int b, int h) {
        length = l;
        breadth = b;
        height = h;
    }

    public static void main(String[] args) {
        Cube1 cubeObj1, cubeObj2;
        cubeObj1 = new Cube1();
        cubeObj2 = new Cube1(10, 20, 30);
        System.out.println("Volume of Cube1 is : " + cubeObj1.getVolume());
        System.out.println("Volume of Cube1 is : " + cubeObj2.getVolume());
    }
}

You need to alias the subquery.

SELECT name FROM (SELECT name FROM agentinformation) a  

or to be more explicit

SELECT a.name FROM (SELECT name FROM agentinformation) a  

A good method which is a favorite of mine and for many I'm sure, is to make use of foreach which will output each color you chose, and appear on screen one underneath each other.

When it comes to using checkboxes, you kind of do not have a choice but to use foreach, and that's why you only get one value returned from your array.

Here is an example using $_GET. You can however use $_POST and would need to make both directives match in both files in order to work properly.

###HTML FORM

<form action="third.php" method="get">
    Red<input type="checkbox" name="color[]" value="red">
    Green<input type="checkbox" name="color[]" value="green">
    Blue<input type="checkbox" name="color[]" value="blue">
    Cyan<input type="checkbox" name="color[]" value="cyan">
    Magenta<input type="checkbox" name="color[]" value="Magenta">
    Yellow<input type="checkbox" name="color[]" value="yellow">
    Black<input type="checkbox" name="color[]" value="black">
    <input type="submit" value="submit">
</form>

###PHP (using $_GET) using third.php as your handler

<?php

$name = $_GET['color'];

// optional
// echo "You chose the following color(s): <br>";

foreach ($name as $color){ 
    echo $color."<br />";
}

?>

Assuming having chosen red, green, blue and cyan as colors, will appear like this:

red
green
blue
cyan

##OPTION #2

You can also check if a color was chosen. If none are chosen, then a seperate message will appear.

<?php

$name = $_GET['color'];

if (isset($_GET['color'])) {

Add one line of code after setContentView() in onCreate()

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_flag);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

This is a method that uses a FileUpload control in asp.net:

byte[] buffer = new byte[fu.FileContent.Length];
Stream s = fu.FileContent;
s.Read(buffer, 0, buffer.Length);
//Then save 'buffer' to the varbinary column in your db where you want to store the image.

I was building a nav menu. I have overflow: hidden in my nav's css which hid everything. I thought it was a z-index problem, but really I was hiding everything outside my nav.

For me this problem was related to the API that I was using not being deployed. For example, I used a ZSDK_API.jar as a reference.

To fix the issue I had to right click on the project and select properties. From JAVA BUILD PATH, I had to add the API that was not being deployed. This was weird as the app was throwing MainActivity class not found and in reality the error was caused by the DiscoveryHandler class not being found.

Hopes this helps someone.

you need declare resources in dispatcher servelet file.below is two declarations

<mvc:annotation-driven />
<mvc:resources location="/resources/" mapping="/resources/**" />

Have you tried this?

ALTER TABLE <table_name> MODIFY <col_name> VARCHAR(65353);

This will change the col_name's type to VARCHAR(65353)

If you want to do it from code behind, try this:

System.Web.UI.ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "AlertBox", "alert('Message');", true);

In Python, there is a fast, iterative way.

def reverse(n):
    newnum=0
    while n>0:
        newnum = newnum*10 + n % 10
        n//=10
    return newnum

def palindrome(n):
    return n == reverse(n)

This also prevents memory issues with recursion (like StackOverflow error in Java)

I had the same issue, for me this fixed the issue:
right click on the project ->maven -> update project

unfortunately we can't use in MySQL after INSERT or UPDATE description, like in Oracle

Building on @SotiriosDelimanolis's comment, here is a method to deal with URLs (such as file:...) and non-URLs (such as C:...), using Spring's FileSystemResource:

public FileSystemResource get(String file) {
    try {
        // First try to resolve as URL (file:...)
        Path path = Paths.get(new URL(file).toURI());
        FileSystemResource resource = new FileSystemResource(path.toFile());
        return resource;
    } catch (URISyntaxException | MalformedURLException e) {
        // If given file string isn't an URL, fall back to using a normal file 
        return new FileSystemResource(file);
    }
}

Generally when I want to create a JSON or YAML string, I start out by building the Perl data structure, and then running a simple conversion on it. You could put a UI in front of the Perl data structure generation, e.g. a web form.

Converting a structure to JSON is very straightforward:

use strict;
use warnings;
use JSON::Any;

my $data = { arbitrary structure in here };
my $json_handler = JSON::Any->new(utf8=>1);
my $json_string = $json_handler->objToJson($data);

Yes you can use .is(':visible') in jquery. But while the code is running under the safari browser .is(':visible') is won't work.

So please use the below code

if( $(".example").offset().top > 0 )

The above line will work both IE as well as safari also.

public string EncryptPassword(string password, string saltorusername)
        {
            using (var sha256 = SHA256.Create())
            {
                var saltedPassword = string.Format("{0}{1}", salt, password);
                byte[] saltedPasswordAsBytes = Encoding.UTF8.GetBytes(saltedPassword);
                return Convert.ToBase64String(sha256.ComputeHash(saltedPasswordAsBytes));
            }
        }

Get the path of running Apache

$ ps -ef | grep apache
apache   12846 14590  0 Oct20 ?        00:00:00 /usr/sbin/apache2

Append -V argument to the path

$ /usr/sbin/apache2 -V | grep SERVER_CONFIG_FILE
-D SERVER_CONFIG_FILE="/etc/apache2/apache2.conf"

Reference:

as @DLeh says Use rather

var controller = DependencyResolver.Current.GetService<ControllerB>();

But, giving the controller, a controlller context is important especially when you need to access the User object, Server object, or the HttpContext inside the 'child' controller.

I have added a line of code:

controller.ControllerContext = new ControllerContext(Request.RequestContext, controller);

or else you could have used System.Web to acces the current context too, to access Server or the early metioned objects

NB: i am targetting the framework version 4.6 (Mvc5)

Normally, if you have installed the JDK6u14, eclipse should detect it and declare it automatically in its "installed JRE" list.

If not, you can add that JDK through "Windows/Preferences": Java > Installed JREs:

Just point to the root directory of your JDK installation: it should include the sources of the JDK (src.zip), automatically detected and attached to rt.jar by eclipse.

Just add <relativePath /> so the parent in pom should look like:

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.4.RELEASE</version>
        <relativePath />
    </parent>

The JavaScript function:

String.prototype.capitalize = function(){
       return this.replace( /(^|\s)([a-z])/g , function(m,p1,p2){ return p1+p2.toUpperCase(); } );
      };

To use this function:

capitalizedString = someString.toLowerCase().capitalize();

Also, this would work on multiple words string.

To make sure the converted City name is injected into the database, lowercased and first letter capitalized, then you would need to use JavaScript before you send it over to server side. CSS simply styles, but the actual data would remain pre-styled. Take a look at this jsfiddle example and compare the alert message vs the styled output.

I got round thid by writing/reading to a file. I guessed cv.imread would put it into the format it needed. This code for anki Vector SDK program but you get the idea.

tmpImage = robot.camera.latest_image.raw_image.save('temp.png')
pilImage = cv.imread('temp.png')

You can use the ID field as the equality identifier. You can't use the adhoc object for this case because AngularJS checks references equality when comparing objects.

<select 
    ng-model="Choice.SelectedOption.ID" 
    ng-options="choice.ID as choice.Name for choice in Choice.Options">
</select>

Wget currently only supports x-www-form-urlencoded data. --post-file is not for transmitting files as form attachments, it expects data with the form: key=value&otherkey=example.

--post-data and --post-file work the same way: the only difference is that --post-data allows you to specify the data in the command line, while --post-file allows you to specify the path of the file that contain the data to send.

Here's the documentation:

 --post-data=string
       --post-file=file
           Use POST as the method for all HTTP requests and send the specified data
           in the request body.  --post-data sends string as data, whereas
           --post-file sends the contents of file.  Other than that, they work in
           exactly the same way. In particular, they both expect content of the
           form "key1=value1&key2=value2", with percent-encoding for special
           characters; the only difference is that one expects its content as a
           command-line parameter and the other accepts its content from a file. In
           particular, --post-file is not for transmitting files as form
           attachments: those must appear as "key=value" data (with appropriate
           percent-coding) just like everything else. Wget does not currently
           support "multipart/form-data" for transmitting POST data; only
           "application/x-www-form-urlencoded". Only one of --post-data and
           --post-file should be specified.

Regarding your authentication token, it should either be provided in the header, in the path of the url, or in the data itself. This must be indicated somewhere in the documentation of the service you use. In a POST request, as in a GET request, you must specify the data using keys and values. This way the server will be able to receive multiple information with specific names. It's similar with variables.

Hence, you can't just send a magic token to the server, you also need to specify the name of the key. If the key is "token", then it should be token=YOUR_TOKEN.

wget --post-data 'user=foo&password=bar' http://example.com/auth.php

Also, you should consider using curl if you can because it is easier to send files using it. There are many examples on the Internet for that.

This is the easiest way I know - host it in the cloud with the Gemfury private npm registry.

It's free and you can log in with your Github account. It should save you a lot of time, compared to setting up your own database.

The ZT Process Executor library is an alternative to Apache Commons Exec. It has functionality to run commands, capturing their output, setting timeouts, etc.

I have not used it yet, but it looks reasonably well-documented.

An example from the documentation: Executing a command, pumping the stderr to a logger, returning the output as UTF8 string.

 String output = new ProcessExecutor().command("java", "-version")
    .redirectError(Slf4jStream.of(getClass()).asInfo())
    .readOutput(true).execute()
    .outputUTF8();

Its documentation lists the following advantages over Commons Exec:

• Improved handling of streams
  • Reading/writing to streams
  • Redirecting stderr to stdout
• Improved handling of timeouts
• Improved checking of exit codes
• Improved API
  • One liners for quite complex use cases
  • One liners to get process output into a String
  • Access to the Process object available
  • Support for async processes ( Future )
• Improved logging with SLF4J API
• Support for multiple processes

def multiples(n,m,starting_from=1,increment_by=1):
    """
    # Where n is the number 10 and m is the number 2 from your example. 
    # In case you want to print the multiples starting from some other number other than 1 then you could use the starting_from parameter
    # In case you want to print every 2nd multiple or every 3rd multiple you could change the increment_by 
    """
    print [ n*x for x in range(starting_from,m+1,increment_by) ] 

I had a .live("focus") event set to select() (highlight) the contents of a text input so that the user wouldn't have to select it before typing a new value.

$(formObj).select();

Because of quirks between different browsers, the select would sometimes be superseded by the click that caused it, and it would deselect the contents right after in favor of placing the cursor within the text field (worked mostly ok in FF but failed in IE)

I thought I could solve this by putting a slight delay on the select...

setTimeout(function(){$(formObj).select();},200);

This worked fine and the select would persist, but a funny problem arose.. If you tabbed from one field to the next, the focus would switch to the next field before the select took place. Since select steals focus, the focus would then go back and trigger a new "focus" event. This ended up in a cascade of input selects dancing all over the screen.

A workable solution would be to check that the field still has focus before executing the select(), but as mentioned, there's no simple way to check... I ended up just dispensing with the whole auto highlight, rather than turning what should be a single jQuery select() call into a huge function laden with subroutines...

I installed Oracle Express Edition and I have the same error. One of the possible reason that is maybe your user does not have permission to open this shortcut. Here is how I solved the problem.

1. Right-click the shortcut and select the properties.

2. Now click the Open File Location. Now you will see there is a Get_Started shortcut.

3. Now right-click the Get_Started and select the properties. Then select your user and give permission to your user in the security tab.
