I am happy with the listings package:

Here is how I configure it:

\lstset{
language=C,
basicstyle=\small\sffamily,
numbers=left,
numberstyle=\tiny,
frame=tb,
columns=fullflexible,
showstringspaces=false
}

I use it like this:

\begin{lstlisting}[caption=Caption example.,
  label=a_label,
  float=t]
// Insert the code here
\end{lstlisting}

The listings package is quite nice and very flexible (e.g. different sizes for comments and code).

Go and buy the book titled "Java examples in a nutshell". In the book you will find most of practical examples.

Another CSV I/O library can be found here:

http://code.google.com/p/fast-cpp-csv-parser/

#include "csv.h"

int main(){
  io::CSVReader<3> in("ram.csv");
  in.read_header(io::ignore_extra_column, "vendor", "size", "speed");
  std::string vendor; int size; double speed;
  while(in.read_row(vendor, size, speed)){
    // do stuff with the data
  }
}

If you're working from some network that requires you to use a proxy in your browser to connect to the internet (likely an office building), that might be it. I had the same issue and adding the proxy configs to the network settings solved it.

• Go to your preferences (Eclipse -> Preferences on a Mac, or Window -> Preferences on a Windows)
• Then -> General -> expand to view the list underneath -> Select Network Connections (don't expand)
• At the top of the page that appears there is a drop down, select "Manual."
• Then select "HTTP" in the list directly below the drop down (which now should have all it's options checked) and then click the "Edit" button to the right of the list.
• Enter in the proxy url and port you need to connect to the internet in your web browser normally.
• Repeat for "HTTPS."

If you don't know the proxy url and port, talk to your network admin.

I think the params config parameter won't work here since it adds the string to the url instead of the body but to add to what Infeligo suggested here is an example of the global override of a default transform (using jQuery param as an example to convert the data to param string).

Set up global transformRequest function:

var app = angular.module('myApp');

app.config(function ($httpProvider) {
    $httpProvider.defaults.transformRequest = function(data){
        if (data === undefined) {
            return data;
        }
        return $.param(data);
    }
});

That way all calls to $http.post will automatically transform the body to the same param format used by the jQuery $.post call.

Note you may also want to set the Content-Type header per call or globally like this:

$httpProvider.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded; charset=UTF-8';

Sample non-global transformRequest per call:

    var transform = function(data){
        return $.param(data);
    }

    $http.post("/foo/bar", requestData, {
        headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'},
        transformRequest: transform
    }).success(function(responseData) {
        //do stuff with response
    });

i'm a huge fan of making an image the background of a div/node -- then you can just use the background-position: center attribute to center it regardless of screen size

I have done this way:

Check these reference screen shots.

Add class FullScreenVideoView.java:

import android.content.Context;
import android.util.AttributeSet;
import android.widget.VideoView;

public class FullScreenVideoView extends VideoView {
    public FullScreenVideoView(Context context) {
        super(context);
    }

    public FullScreenVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public FullScreenVideoView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec){
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        setMeasuredDimension(widthMeasureSpec, heightMeasureSpec);
    }
}

How to bind with xml:

<FrameLayout
   android:id="@+id/secondMedia"
   android:layout_width="match_parent"
   android:layout_height="match_parent">

     <com.my.package.customview.FullScreenVideoView
           android:layout_width="match_parent"
           android:layout_height="match_parent" 
           android:id="@+id/fullScreenVideoView"/>

</FrameLayout>

Hope this will help you.

<textarea name='Status'> </textarea>
<input type='button' value='Status Update'>

You have few problems with your code like using . for concatenation

Try this -

$(function () {
    $('input').on('click', function () {
        var Status = $(this).val();
        $.ajax({
            url: 'Ajax/StatusUpdate.php',
            data: {
                text: $("textarea[name=Status]").val(),
                Status: Status
            },
            dataType : 'json'
        });
    });
});

In 2017, the thing closest to Javadoc would probably DocFx which was developed by Microsoft and comes as a Commmand-Line-Tool as well as a VS2017 plugin.

It's still a little rough around the edges but it looks promising.

Another alternative would be Wyam which has a documentation recipe suitable for net aplications. Look at the cake documentation for an example.

Neither is better than the other, they do exactly the same thing. However, using .encode() and .decode() is the more common way to do it. It is also compatible with Python 2.

In my case I ran on this problem while using Edge.js — all the problem was a JavaScript syntax error inside a C# Edge.js function definition.

The NSURLErrorDomain error codes are listed here https://developer.apple.com/documentation/foundation/1508628-url_loading_system_error_codes

However, 400 is just the http status code (http://www.w3.org/Protocols/HTTP/HTRESP.html) being returned which means you've got something wrong with your request.

We published it today after having 'Release this version'. It took 15 minutes to show on the App Store.

This is due to App Store will sync the data across servers.

Don't build directory and file names your self, use python's included libraries.

In this case the relevant one is os.path. Especially join which creates a new pathname from a directory and a file name or directory and split that gets the filename from a full path.

Your example would be

pathfile=os.path.dirname(templateFile)
p = os.path.join(pathfile, 'output')
p = os.path.join( p, 'log.txt')
rootTree.write(p)

$servername = "localhost";

$username = "username";

$password = "password";

$dbname = "myDB";


// Create connection

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection

if ($conn->connect_error) {

die("Connection failed: " . $conn->connect_error);
}

$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]');";

$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', '[email protected]');";

$sql .= "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', '[email protected]')";


 if ($conn->multi_query($sql) === TRUE) {

  echo "New records created successfully";

 } else {

   echo "Error: " . $sql . "<br>" . $conn->error;

}

$conn->close();

After some fiddling with a script I came to this action. Copy and save it in a .bat file:

FOR /F "usebackq tokens=5" %%i IN (`netstat -aon ^| find "3306"`) DO taskkill /F /PID %%i

Change 'find "3306"' in the port number which needs to be free. Then run the file as administrator. It will kill all the processes running on this port.

I think you have to calculate latitudine min and longitude min: Here is an Example with the function to use to center your point:

//Example values of min & max latlng values
var lat_min = 1.3049337;
var lat_max = 1.3053515;
var lng_min = 103.2103116;
var lng_max = 103.8400188;

map.setCenter(new google.maps.LatLng(
  ((lat_max + lat_min) / 2.0),
  ((lng_max + lng_min) / 2.0)
));
map.fitBounds(new google.maps.LatLngBounds(
  //bottom left
  new google.maps.LatLng(lat_min, lng_min),
  //top right
  new google.maps.LatLng(lat_max, lng_max)
));

My issue was really difficult to track down. In the end, the problem was occurring when the web page had missing images. The src was missing a Url. This was happening on an MVC 5 Web Controller. To fix the issue, I included transparent images when no real image is available.

<img alt="" class="logo" src="">

[attr.disabled]="valid == true ? true : null"

You have to use null to remove attr from html element.

using bash's set -o pipefail is helpful

pipefail: the return value of a pipeline is the status of the last command to exit with a non-zero status, or zero if no command exited with a non-zero status

you can just use this code to hit the script using cron job using cpanel:

wget https://www.example.co.uk/unique-code

A common way to achieve what you desire is to use the ADB pull command.

Another way I prefer in most cases is to copy the database by code to SD card:

try {
    File sd = Environment.getExternalStorageDirectory();

    if (sd.canWrite()) {
        String currentDBPath = "/data/data/" + getPackageName() + "/databases/yourdatabasename";
        String backupDBPath = "backupname.db";
        File currentDB = new File(currentDBPath);
        File backupDB = new File(sd, backupDBPath);

        if (currentDB.exists()) {
            FileChannel src = new FileInputStream(currentDB).getChannel();
            FileChannel dst = new FileOutputStream(backupDB).getChannel();
            dst.transferFrom(src, 0, src.size());
            src.close();
            dst.close();
        }
    }
} catch (Exception e) {

}

Don't forget to set the permission to write on SD in your manifest, like below.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

One thing I've learnt the hard way is being consistent

Watch out for mixing:

 import { BehaviorSubject } from "rxjs";

with

 import { BehaviorSubject } from "rxjs/BehaviorSubject";

This will probably work just fine UNTIL you try to pass the object to another class (where you did it the other way) and then this can fail

 (myBehaviorSubject instanceof Observable)

It fails because the prototype chain will be different and it will be false.

I can't pretend to understand exactly what is happening but sometimes I run into this and need to change to the longer format.

Update: Google Forms can now upload files. This answer was posted before Google Forms had the capability to upload files.

This solution does not use Google Forms. This is an example of using an Apps Script Web App, which is very different than a Google Form. A Web App is basically a website, but you can't get a domain name for it. This is not a modification of a Google Form, which can't be done to upload a file.

NOTE: I did have an example of both the UI Service and HTML Service, but have removed the UI Service example, because the UI Service is deprecated.

NOTE: The only sandbox setting available is now IFRAME. I you want to use an onsubmit attribute in the beginning form tag: <form onsubmit="myFunctionName()">, it may cause the form to disappear from the screen after the form submission.

If you were using NATIVE mode, your file upload Web App may no longer be working. With NATIVE mode, a form submission would not invoke the default behavior of the page disappearing from the screen. If you were using NATIVE mode, and your file upload form is no longer working, then you may be using a "submit" type button. I'm guessing that you may also be using the "google.script.run" client side API to send data to the server. If you want the page to disappear from the screen after a form submission, you could do that another way. But you may not care, or even prefer to have the page stay on the screen. Depending upon what you want, you'll need to configure the settings and code a certain way.

If you are using a "submit" type button, and want to continue to use it, you can try adding event.preventDefault(); to your code in the submit event handler function. Or you'll need to use the google.script.run client side API.

A custom form for uploading files from a users computer drive, to your Google Drive can be created with the Apps Script HTML Service. This example requires writing a program, but I've provide all the basic code here.

This example shows an upload form with Google Apps Script HTML Service.

What You Need

• Google Account
• Google Drive
• Google Apps Script - also called Google Script

Google Apps Script

There are various ways to end up at the Google Apps Script code editor.

• Load Apps Script directly from the web address: https://script.google.com
• Open a Google Sheet first, then open Apps Script
• Go to your Google Drive, then Open Apps Script: https://drive.google.com/drive/#my-drive
• Go to your Google Drive, then click on an Apps Script project file
• Open Apps Script from Google Docs
• etc

I mention this because if you are not aware of all the possibilities, it could be a little confusing. Google Apps Script can be embedded in a Google Site, Sheets, Docs or Forms, or used as a stand alone app.

Apps Script Overview

This example is a "Stand Alone" app with HTML Service.

HTML Service - Create a web app using HTML, CSS and Javascript

Google Apps Script only has two types of files inside of a Project:

• Script
• HTML

Script files have a .gs extension. The .gs code is a server side code written in JavaScript, and a combination of Google's own API.

• Copy and Paste the following code

• Save It

• Create the first Named Version

• Publish it

• Set the Permissions

  and you can start using it.

Start by:

• Create a new Blank Project in Apps Script
• Copy and Paste in this code:

Upload a file with HTML Service:

Code.gs file (Created by Default)

//For this to work, you need a folder in your Google drive named:
// 'For Web Hosting'
// or change the hard coded folder name to the name of the folder
// you want the file written to

function doGet(e) {
  return HtmlService.createTemplateFromFile('Form')
    .evaluate() // evaluate MUST come before setting the Sandbox mode
    .setTitle('Name To Appear in Browser Tab')
    .setSandboxMode();//Defaults to IFRAME which is now the only mode available
}

function processForm(theForm) {
  var fileBlob = theForm.picToLoad;
  
  Logger.log("fileBlob Name: " + fileBlob.getName())
  Logger.log("fileBlob type: " + fileBlob.getContentType())
  Logger.log('fileBlob: ' + fileBlob);

  var fldrSssn = DriveApp.getFolderById(Your Folder ID);
    fldrSssn.createFile(fileBlob);
    
  return true;
}

Create an html file:

<!DOCTYPE html>
<html>
  <head>
    <base target="_top">
  </head>
  <body>
    <h1 id="main-heading">Main Heading</h1>
    <br/>
    <div id="formDiv">

      <form id="myForm">
    
        <input name="picToLoad" type="file" /><br/>
        <input type="button" value="Submit" onclick="picUploadJs(this.parentNode)" />
          
      </form>
    </div>


  <div id="status" style="display: none">
  <!-- div will be filled with innerHTML after form submission. -->
  Uploading. Please wait...
</div>

</body>
<script>

function picUploadJs(frmData) {

  document.getElementById('status').style.display = 'inline';

  google.script.run
    .withSuccessHandler(updateOutput)
    .processForm(frmData)
};
  // Javascript function called by "submit" button handler,
  // to show results.
  
  function updateOutput() {
  
    var outputDiv = document.getElementById('status');
    outputDiv.innerHTML = "The File was UPLOADED!";
  }

</script>
</html>

This is a full working example. It only has two buttons and one <div> element, so you won't see much on the screen. If the .gs script is successful, true is returned, and an onSuccess function runs. The onSuccess function (updateOutput) injects inner HTML into the div element with the message, "The File was UPLOADED!"

• Save the file, give the project a name
• Using the menu: File, Manage Version then Save the first Version
• Publish, Deploy As Web App then Update

When you run the Script the first time, it will ask for permissions because it's saving files to your drive. After you grant permissions that first time, the Apps Script stops, and won't complete running. So, you need to run it again. The script won't ask for permissions again after the first time.

The Apps Script file will show up in your Google Drive. In Google Drive you can set permissions for who can access and use the script. The script is run by simply providing the link to the user. Use the link just as you would load a web page.

Another example of using the HTML Service can be seen at this link here on StackOverflow:

File Upload with HTML Service

NOTES about deprecated UI Service:

There is a difference between the UI Service, and the Ui getUi() method of the Spreadsheet Class (Or other class) The Apps Script UI Service was deprecated on Dec. 11, 2014. It will continue to work for some period of time, but you are encouraged to use the HTML Service.

Google Documentation - UI Service

Even though the UI Service is deprecated, there is a getUi() method of the spreadsheet class to add custom menus, which is NOT deprecated:

Spreadsheet Class - Get UI method

I mention this because it could be confusing because they both use the terminology UI.

The UI method returns a Ui return type.

You can add HTML to a UI Service, but you can't use a <button>, <input> or <script> tag in the HTML with the UI Service.

Here is a link to a shared Apps Script Web App file with an input form:

Shared File - Contact Form

The PIL distribution is mispackaged for egg installation.

Install Pillow instead, the friendly PIL fork.

LocalLinks now seems to be obsolete.

LocalExplorer seems to have taken it's place and provides similar functionality:

https://chrome.google.com/webstore/detail/local-explorer-file-manag/eokekhgpaakbkfkmjjcbffibkencdfkl/reviews?hl=en

It's basically a chrome plugin that replaces file:// links with localexplorer:// links, combined with an installable protocol handler that intercepts localexplorer:// links.

Best thing I can find available right now, I have no affiliation with the developer.

Run this in command prompt:

netstat -ano | find ":80"

It will show you what process (PID) is listening on port 80.

From there you can open task manager, make sure you have PID selected in columns view option, and find the matching PID to find what process it is.

If its svchost.exe you'll have to dig more (see tasklist /svc).

I had this happen to me recently and it wasn't any of the popular answers like Skype either, could be Adobe, Java, anything really.

We can have two ways of calling the functions written in pgadmin for postgre sql database.

Suppose we have defined the function as below:

CREATE OR REPLACE FUNCTION helloWorld(name text) RETURNS void AS $helloWorld$
DECLARE
BEGIN
    RAISE LOG 'Hello, %', name;
END;
$helloWorld$ LANGUAGE plpgsql;

We can call the function helloworld in one of the following way:

SELECT "helloworld"('myname');

SELECT public.helloworld('myname')

This is actually more simple than you'd think: "Just" copy the HTML table (that is: The HTML code for the table) into the clipboard. Excel knows how to decode HTML tables; it'll even try to preserve the attributes.

The hard part is "copy the table into the clipboard" since there is no standard way to access the clipboard from JavaScript. See this blog post: Accessing the System Clipboard with JavaScript – A Holy Grail?

Now all you need is the table as HTML. I suggest jQuery and the html() method.

DateTime is not standard nullable type. If you want assign null to DateTime type of variable, you have to use DateTime? type which supports null value.

If you only want test your variable to be set (e.g. variable holds other than default value), you can use keyword "default" like in following code:

if (dateTimeVariable == default(DateTime))
{
    //do work for dateTimeVariable == null situation
}

I tried all these method but none worked for me. I removed .git file using rm -rf .git form the local repository and then again did git init and git add and routine commands. It worked.

This can be done with MySQL, although it's highly unintuitive:

CREATE PROCEDURE p25 (OUT return_val INT)
BEGIN
  DECLARE a,b INT;
  DECLARE cur_1 CURSOR FOR SELECT s1 FROM t;
  DECLARE CONTINUE HANDLER FOR NOT FOUND
  SET b = 1;
  OPEN cur_1;
  REPEAT
    FETCH cur_1 INTO a;
    UNTIL b = 1
  END REPEAT;
  CLOSE cur_1;
  SET return_val = a;
END;//

Check out this guide: mysql-storedprocedures.pdf

Try this

let path = "/{id}/{name}/{age}";
const paramsPattern = /[^{\}]+(?=})/g;
let extractParams = path.match(paramsPattern);
console.log("extractParams", extractParams) // prints all the names between {} = ["id", "name", "age"]

ASP.Net Web API has Authorization Server build-in already. You can see it inside Startup.cs when you create a new ASP.Net Web Application with Web API template.

OAuthOptions = new OAuthAuthorizationServerOptions
{
    TokenEndpointPath = new PathString("/Token"),
    Provider = new ApplicationOAuthProvider(PublicClientId),
    AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
    AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
    // In production mode set AllowInsecureHttp = false
    AllowInsecureHttp = true
};

All you have to do is to post URL encoded username and password inside query string.

/Token/userName=johndoe%40example.com&password=1234&grant_type=password

If you want to know more detail, you can watch User Registration and Login - Angular Front to Back with Web API by Deborah Kurata.

Its quite easy on computer a you don't need to do anything just make sure both system are on same network if its not internet access(for this you need static ip). Okay now on computer b go to start menu find configuration under oracle folder click Net Configuration Assistant under that folder when window pop up click Local net configuration option it must be third option.

Now click add and click next in next screen it will ask service name here you need to add oracle global database name of computer A(Normally I use oracle86 for my installation) now click next next screen choose protocol normally its tcp click next in host name enter computer A's name you can found that in my computer properties. Click next don't change port untill you have changed that in Computer A click next and choose test connection now here you can check your connection working or not if the error is username and password not correct then click login credential button and fill correct username and password. If its saying unable to reach computer ot target not found than you must add exception in firewall for 1521 port or just disable firewall on computer A.

Or, once it's already in SSIS, you could create a derived column (as part of some data flow task) with:

(DT_I8)FLOOR((DT_R8)systemDateTime)

But you'd have to test to doublecheck.

Correct; you cannot truncate a table which has an FK constraint on it.

Typically my process for this is:

1. Drop the constraints
2. Trunc the table
3. Recreate the constraints.

(All in a transaction, of course.)

Of course, this only applies if the child has already been truncated. Otherwise I go a different route, dependent entirely on what my data looks like. (Too many variables to get into here.)

The original poster determined WHY this is the case; see this answer for more details.

An easy solution which avoids looping over the ticklabes is to just use

fig.autofmt_xdate()

This command automatically rotates the xaxis labels and adjusts their position. The default values are a rotation angle 30° and horizontal alignment "right". But they can be changed in the function call

fig.autofmt_xdate(bottom=0.2, rotation=30, ha='right')

The additional bottom argument is equivalent to setting plt.subplots_adjust(bottom=bottom), which allows to set the bottom axes padding to a larger value to host the rotated ticklabels.

So basically here you have all the settings you need to have a nice date axis in a single command.

A good example can be found on the matplotlib page.

Just an FYI, you don't need to use CSS classes to accomplish this.

You can write the following line of code to get the correct control name on the client:

$("#<%= statusDDL.ClientID %>").val("2");

ASP.NET will render the control ID correctly inside the jQuery.

Ok. As the other answerers explained, a stack is a last-in, first-out data structure. You add an element to the top of the stack with a Push operation. You take an element off the top with a Pop operation. The elements are removed in reverse order to the order they were put inserted (hence Last In, First Out). For example, if you push the elments 1,2,3 in that order, the number 3 will be at the top of the stack. A Pop operation will remove it (it was the last in) and leave 2 at the top of the stack.

Regarding the rest of the lecture, the lecturer tried to describe a stack-based machine that evaluates arithmetic expressions. The machine operates by continuously popping 3 elements from the top of the stack. The first two elements are operands and the third is an operator (+, -, *, /). It then applies this operator on the operands, and pushes the result onto the stack. The process continues until there is only one element on the stack, which is the value of the expression.

So, suppose we begin by pushing the values "+/*23-21*5-41" in left-to-right order onto the stack. We then pop 3 elements from the top. The last in is first out, which means the first 3 element are "1", "4", and "-" in that order. We push the number 3 (the result of 4-1) onto the stack, then pop the three topmost elements: 3, 5, *. Push the result, 15, onto the stack, and so on.

"By the way...... How to refresh it every time so it print mi in one place just change the number."

It's really tricky topic. What zack suggested ( outputting console control codes ) is one way to achieve that.

You can use (n)curses, but that works mainly on *nixes.

On Windows (and here goes interesting part) which is rarely mentioned (I can't understand why) you can use Python bindings to WinAPI (http://sourceforge.net/projects/pywin32/ also with ActivePython by default) - it's not that hard and works well. Here's a small example:

import win32console, time

output_handle = win32console.GetStdHandle(  win32console.STD_OUTPUT_HANDLE )
info = output_handle.GetConsoleScreenBufferInfo()
pos = info["CursorPosition"]

for i in "\\|/-\\|/-":
    output_handle.WriteConsoleOutputCharacter( i, pos )
    time.sleep( 1 )

Or, if you want to use print (statement or function, no difference):

import win32console, time

output_handle = win32console.GetStdHandle(  win32console.STD_OUTPUT_HANDLE )
info = output_handle.GetConsoleScreenBufferInfo()
pos = info["CursorPosition"]

for i in "\\|/-\\|/-":

win32console module enables you to do many more interesting things with windows console... I'm not a big fan of WinAPI, but recently I realized that at least half of my antipathy towards it was caused by writing WinAPI code in C - pythonic bindings are much easier to use.

All other answers are great and pythonic, of course, but... What if I wanted to print on previous line? Or write multiline text, than clear it and write the same lines again? My solution makes that possible.

Try this : Using this you can select date by last 30 days,

SELECT DATEADD(DAY,-30,GETDATE())

Be sure that android:debuggable="true" is set in the application tag of your manifest file, and then:

1. Plug your phone into your computer and enable USB debugging on the phone
2. Open eclipse and a workspace containing the code for your app
3. In Eclipse, go to Window->Show View->Devices
4. Look at the Devices view which should now be visible, you should see your device listed
5. If your device isn't listed, you'll have to track down the ADB drivers for your phone before continuing
6. If you want to step through code, set a breakpoint somewhere in your app
7. Open the app on your phone
8. In the Devices view, expand the entry for your phone if it isn't already expanded, and look for your app's package name.
9. Click on the package name, and in the top right of the Devices view you should see a green bug along with a number of other small buttons. Click the green bug.
10. You should now be attached/debugging your app.

There's also the function tags, a bit more flexible:

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
<c:if test="${fn:length(list) > 0}">

And here's the tag documentation.

Unlike other languages you may be used to, everything in C++ has to be declared before it can be used. The compiler will read your source file from top to bottom, so when it gets to the call to swapCase, it doesn't know what it is so you get an error. You can declare your function ahead of main with a line like this:

void swapCase(char *name);

or you can simply move the entirety of that function ahead of main in the file. Don't worry about having the seemingly most important function (main) at the bottom of the file. It is very common in C or C++ to do that.

The problem is that you define it inside the class, which

a) means the second argument is implicit (this) and

b) it will not do what you want it do, namely extend std::ostream.

You have to define it as a free function:

class A { /* ... */ };
std::ostream& operator<<(std::ostream&, const A& a);

Your question is vague but you could use ShowDialog to display form 2. Then when you close form 2, pass a DialogResult object back to let the user know how the form was closed - if the user clicked the button, then close form 1 as well.

A workaround for CONTAINS: If you don't want to create a full text Index on the column, and performance is not one of your priorities you could use the LIKE statement which doesn't need any prior configuration:

Example: find all Products that contains the letter Q:

SELECT ID, ProductName
FROM [ProductsDB].[dbo].[Products]
WHERE [ProductsDB].[dbo].[Products].ProductName LIKE '%Q%'

Status 301 means that the resource (page) is moved permanently to a new location. The client/browser should not attempt to request the original location but use the new location from now on.

Status 302 means that the resource is temporarily located somewhere else, and the client/browser should continue requesting the original url.

Android parcable has some unique things. Those are given bellow:

1. You have to read Parcel as the same order where you put data on parcel.
2. Parcel will empty after read from parcel. That is if you have 3 data on your parcel. Then after read 3 times parcel will be empty.

Example: To make a class Parceble it must be implement Parceble. Percable has 2 method:

int describeContents();
void writeToParcel(Parcel var1, int var2);

Suppose you have a Person class and it has 3 field, firstName,lastName and age. After implementing Parceble interface. this interface is given bellow:

import android.os.Parcel;
import android.os.Parcelable;
public class Person implements Parcelable{
    private String firstName;
    private String lastName;
    private int age;

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getAge() {
        return age;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel parcel, int i) {
        parcel.writeString(firstName);
        parcel.writeString(lastName);
        parcel.writeInt(age);
    }

}

Here writeToParcel method we are writing/adding data on Parcel in an order. After this we have to add bellow code for reading data from parcel:

protected Person(Parcel in) {
        firstName = in.readString();
        lastName = in.readString();
        age = in.readInt();
    }

    public static final Creator<Person> CREATOR = new Creator<Person>() {
        @Override
        public Person createFromParcel(Parcel in) {
            return new Person(in);
        }

        @Override
        public Person[] newArray(int size) {
            return new Person[size];
        }
    };

Here, Person class is taking a parcel and getting data in same an order during writing.

Now during intent getExtra and putExtra code is given bellow:

Put in Extra:

Person person=new Person();
                person.setFirstName("First");
                person.setLastName("Name");
                person.setAge(30);

                Intent intent = new Intent(getApplicationContext(), SECOND_ACTIVITY.class);
                intent.putExtra()
                startActivity(intent); 

Get Extra:

Person person=getIntent().getParcelableExtra("person");

Full Person class is given bellow:

import android.os.Parcel;
import android.os.Parcelable;

public class Person implements Parcelable{
    private String firstName;
    private String lastName;
    private int age;



    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public int getAge() {
        return age;
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel parcel, int i) {
        parcel.writeString(firstName);
        parcel.writeString(lastName);
        parcel.writeInt(age);
    }

    protected Person(Parcel in) {
        firstName = in.readString();
        lastName = in.readString();
        age = in.readInt();
    }

    public static final Creator<Person> CREATOR = new Creator<Person>() {
        @Override
        public Person createFromParcel(Parcel in) {
            return new Person(in);
        }

        @Override
        public Person[] newArray(int size) {
            return new Person[size];
        }
    };

}

Hope this will help you 
Thanks :)

Found the port esp32 was connected to by -

ls /dev/*

You would get a long list and you can find the port you need

According to this MSDN entry, the limit is 1 million rows. You could be running in compatibility mode, which would limit you to the old standard of 65k. Does your excel say compatibility mode in the title? If so, you can save the file as a new style file under the "save as" menu, or change your default to always use the 2007 file standard.

.selector{width:calc(100% / 3);}

You can make surround the element with a href tags or you can use jquery and use

$('').click(function(e){
e.preventDefault();
//DO SOMETHING
});

Call "setWarningMsg()" Method and pass the text that you want to show.

exm:- setWarningMsg("thank you for using java");


public static void setWarningMsg(String text){
    Toolkit.getDefaultToolkit().beep();
    JOptionPane optionPane = new JOptionPane(text,JOptionPane.WARNING_MESSAGE);
    JDialog dialog = optionPane.createDialog("Warning!");
    dialog.setAlwaysOnTop(true);
    dialog.setVisible(true);
}

Or Just use

JOptionPane optionPane = new JOptionPane("thank you for using java",JOptionPane.WARNING_MESSAGE);
JDialog dialog = optionPane.createDialog("Warning!");
dialog.setAlwaysOnTop(true); // to show top of all other application
dialog.setVisible(true); // to visible the dialog

You can use JOptionPane. (WARNING_MESSAGE or INFORMATION_MESSAGE or ERROR_MESSAGE)

I think the best way is by using TableAdapters rather than using Commands objects, its Update method sends all changes mades (Updates,Inserts and Deletes) inside a Dataset or DataTable straight TO the database. Usually when using a DataGridView you bind to a BindingSource which lets you interact with a DataSource such as Datatables or Datasets.

If you work like this, then on your bounded DataGridView you can just do:

this.customersBindingSource.EndEdit();
this.myTableAdapter.Update(this.myDataSet.Customers);

The 'customersBindingSource' is the DataSource of the DataGridView.

The adapter's Update method will update a single data table and execute the correct command (INSERT, UPDATE, or DELETE) based on the RowState of each data row in the table.

From: https://msdn.microsoft.com/en-us/library/ms171933.aspx

So any changes made inside the DatagridView will be reflected on the Database when using the Update method.

More about TableAdapters: https://msdn.microsoft.com/en-us/library/bz9tthwx.aspx

It's a hex number and is 16 decimal.

Send the following headers before outputting the file:

header("Content-Disposition: attachment; filename=\"" . basename($File) . "\"");
header("Content-Type: application/octet-stream");
header("Content-Length: " . filesize($File));
header("Connection: close");

@grom: Interesting about the 'application/octet-stream' MIME type. I wasn't aware of that, have always just used 'application/force-download' :)

Pick up a copy of 'JavaScript design patterns' by Dustin Diaz. There's a few chapters dedicated to implementing JavaScript interfaces through Duck Typing. It's a nice read as well. But no, there's no language native implementation of an interface, you have to Duck Type.

// example duck typing method
var hasMethods = function(obj /*, method list as strings */){
    var i = 1, methodName;
    while((methodName = arguments[i++])){
        if(typeof obj[methodName] != 'function') {
            return false;
        }
    }
    return true;
}

// in your code
if(hasMethods(obj, 'quak', 'flapWings','waggle')) {
    //  IT'S A DUCK, do your duck thang
}

>>> import datetime
>>> d = datetime.datetime.now()
>>> d.strftime('X%d/X%m/%Y').replace('X0','X').replace('X','')
'5/5/2011'

You can use this commands:

docker exec -it yournamecontainer psql -U postgres -c "CREATE DATABASE mydatabase ENCODING 'LATIN1' TEMPLATE template0 LC_COLLATE 'C' LC_CTYPE 'C';"

docker exec -it yournamecontainer psql -U postgres -c "GRANT ALL PRIVILEGES ON DATABASE postgres TO postgres;"

Here's something that I just wrote along those lines::

#include <random>
#include <chrono>
#include <thread>

    uniform_real_distribution<double>  dist;

    backoff_time_t() : rd{}, mt{rd()}, dist{0.5, 1.5} {}

    double rand() {
      return dist(mt);
    }
};

thread_local backoff_time_t backoff_time;

   double x4 = backoff_time.rand();
   return 0;

I tested the previous answers found here: Assuming that we want the other four sheets to remain, the previous answers here did not work, because the other four sheets were deleted. In case we want them to remain use xlwings:

import xlwings as xw
import pandas as pd

filename = "test.xlsx"

df = pd.DataFrame([
    ("a", 1, 8, 3),
    ("b", 1, 2, 5),
    ("c", 3, 4, 6),
    ], columns=['one', 'two', 'three', "four"])

app = xw.App(visible=False)
wb = xw.Book(filename)
ws = wb.sheets["Sheet5"]

ws.clear()
ws["A1"].options(pd.DataFrame, header=1, index=False, expand='table').value = df

# If formatting of column names and index is needed as xlsxwriter does it, 
# the following lines will do it (if the dataframe is not multiindex).
ws["A1"].expand("right").api.Font.Bold = True
ws["A1"].expand("down").api.Font.Bold = True
ws["A1"].expand("right").api.Borders.Weight = 2
ws["A1"].expand("down").api.Borders.Weight = 2

wb.save(filename)
app.quit()

The first allocates an object with automatic storage duration, which means it will be destructed automatically upon exit from the scope in which it is defined.

The second allocated an object with dynamic storage duration, which means it will not be destructed until you explicitly use delete to do so.

Here is answer for your question.

db.getCollection('users').aggregate([
    {$match : {admin : 1}},
    {$lookup: {from: "posts",localField: "_id",foreignField: "owner_id",as: "posts"}},
    {$project : {
            posts : { $filter : {input : "$posts"  , as : "post", cond : { $eq : ['$$post.via' , 'facebook'] } } },
            admin : 1

        }}

])

Or either you can go with mongodb group option.

db.getCollection('users').aggregate([
    {$match : {admin : 1}},
    {$lookup: {from: "posts",localField: "_id",foreignField: "owner_id",as: "posts"}},
    {$unwind : "$posts"},
    {$match : {"posts.via":"facebook"}},
    { $group : {
            _id : "$_id",
            posts : {$push : "$posts"}
    }}
])

This is a solution. Later you can split by ":" and take the values of the array

 /**
 * Converts milliseconds to human readeable language separated by ":"
 * Example: 190980000 --> 2:05:3 --> 2days 5hours 3min
 */
function dhm(t){
    var cd = 24 * 60 * 60 * 1000,
        ch = 60 * 60 * 1000,
        d = Math.floor(t / cd),
        h = '0' + Math.floor( (t - d * cd) / ch),
        m = '0' + Math.round( (t - d * cd - h * ch) / 60000);
    return [d, h.substr(-2), m.substr(-2)].join(':');
}

//Example
var delay = 190980000;                   
var fullTime = dhm(delay);
console.log(fullTime);

Unions are great. One clever use of unions I've seen is to use them when defining an event. For example, you might decide that an event is 32 bits.

Now, within that 32 bits, you might like to designate the first 8 bits as for an identifier of the sender of the event... Sometimes you deal with the event as a whole, sometimes you dissect it and compare it's components. unions give you the flexibility to do both.

union Event
{
  unsigned long eventCode;
  unsigned char eventParts[4];
};

Interpreted language is executed at the run time according to the instructions like in shell scripting and compiled language is one which is compiled (changed into Assembly language, which CPU can understand ) and then executed like in c++.

I believe the following should work with many well-behaved classed in Python:

def copy(obj):
    return type(obj)(obj)

(Of course, I am not talking here about "deep copies," which is a different story, and which may be not a very clear concept -- how deep is deep enough?)

According to my tests with Python 3, for immutable objects, like tuples or strings, it returns the same object (because there is no need to make a shallow copy of an immutable object), but for lists or dictionaries it creates an independent shallow copy.

Of course this method only works for classes whose constructors behave accordingly. Possible use cases: making a shallow copy of a standard Python container class.

To compare between latest commit of current branch and a tag:

git log --pretty=oneline HEAD...tag

Try this

string[] keys = Request.Form.AllKeys;
var value = "";
for (int i= 0; i < keys.Length; i++) 
{
   // here you get the name eg test[0].quantity
   // keys[i];
   // to get the value you use
   value = Request.Form[keys[i]];
}

SELECT DISTINCT 
FIRST_VALUE(ID) OVER (Partition by Game ORDER BY Point) AS ID,
Game,
FIRST_VALUE(Point) OVER (Partition by Game ORDER BY Point) AS Point
FROM #T

loc: only work on index
iloc: work on position
at: get scalar values. It's a very fast loc
iat: Get scalar values. It's a very fast iloc

Also,

at and iat are meant to access a scalar, that is, a single element in the dataframe, while loc and iloc are ments to access several elements at the same time, potentially to perform vectorized operations.

http://pyciencia.blogspot.com/2015/05/obtener-y-filtrar-datos-de-un-dataframe.html

I think it should be like this..

<?php
require_once ( 'username.php' );

echo '
<form name="form1" method="post" action="<?php username() ?>">
 <p>
  <label>
   <input type="text" name="textfield" id="textfield">
  </label>
 </p>
 <p>
  <label>
   <input type="submit" name="button" id="button" value="Submit">
  </label>
 </p>
</form>';
?>

Another option is to insert a minipage in each cell where text wrapping is desired, e.g.:

\begin{table}[H]
\begin{tabular}{l}
\begin{minipage}[t]{0.8\columnwidth}%
a very long line a very long line a very long line a very long line
a very long line a very long line a very long line a very long line
a very long line a very long line a very long line %
\end{minipage}\tabularnewline
\end{tabular}
\end{table}

You can use numpy:

import numpy as np

Example from Empty Array:

np.empty([2, 2])
array([[ -9.74499359e+001,   6.69583040e-309],
       [  2.13182611e-314,   3.06959433e-309]])  

Just put the following below your form. Make sure your input fields are required.

<script>
    var forms = document.getElementsByTagName('form');
    for (var i = 0; i < forms.length; i++) {
        forms[i].noValidate = true;
        forms[i].addEventListener('submit', function(event) {
            if (!event.target.checkValidity()) {
                event.preventDefault();
                alert("Please complete all fields and accept the terms.");
            }
        }, false);
    }
</script>

The first step is figuring out what the error actually is. In order to do this expand your MsBuild output to be diagnostic. This will reveal the actual command executed and hopefully the full error message as well

• Tools -> Options
• Projects and Solutions -> Build and Run
• Change "MsBuild project build output verbosity" to "Diagnostic".

An enum is only guaranteed to be large enough to hold int values. The compiler is free to choose the actual type used based on the enumeration constants defined so it can choose a smaller type if it can represent the values you define. If you need enumeration constants that don't fit into an int you will need to use compiler-specific extensions to do so.

select * from *table_name* where *datetime_column* between '01/01/2009' and curdate()

or using >= and <= :

select * from *table_name* where *datetime_column* >= '01/01/2009' and *datetime_column* <= curdate()

You can also use FormData (But not available in IE):

var formData = new FormData(document.getElementsByName('yourForm')[0]);// yourForm: form selector        
$.ajax({
    type: "POST",
    url: "yourURL",// where you wanna post
    data: formData,
    processData: false,
    contentType: false,
    error: function(jqXHR, textStatus, errorMessage) {
        console.log(errorMessage); // Optional
    },
    success: function(data) {console.log(data)} 
});

This is how you use FormData.

You can collect the values, and convert it from Array to Hash again.

Like this:

config = Hash[ config.collect {|k,v| [k, v.upcase] } ]

Just use the vector constructor.

std::vector<int>   data();
// Load Z elements into data so that Z > Y > X

std::vector<int>   sub(&data[100000],&data[101000]);

Workaround using angular and localforage:

angular.module('app').service('cacheService', function() {

  return {
    set: function(key, value, expireTimeInSeconds) {
      return localforage.setItem(key, {
        data: value,
        timestamp: new Date().getTime(),
        expireTimeInMilliseconds: expireTimeInSeconds * 1000
      })
    },
    get: function(key) {
      return localforage.getItem(key).then(function(item) {
        if(!item || new Date().getTime() > (item.timestamp + item.expireTimeInMilliseconds)) {
          return null
        } else {
          return item.data
        }
      })
    }
  }

})

give the td padding

You can't move a mouse but can lock it. Note: that you must call requestPointerLock in click event.

Small Example:

var canvas = document.getElementById('mycanvas');
canvas.requestPointerLock = canvas.requestPointerLock || canvas.mozRequestPointerLock || canvas.webkitRequestPointerLock;
canvas.requestPointerLock();

Documentation and full code example:

https://developer.mozilla.org/en-US/docs/Web/API/Pointer_Lock_API

Unlike traditional RBDMs, mongoDB doesn't allow you to define any random field as the primary key, the _id field MUST exist for all standard documents.

For this reason, it doesn't make sense to create a separate uuid field.

In mongoose, the ObjectId type is used not to create a new uuid, rather it is mostly used to reference other documents.

Here is an example:

var mongoose = require('mongoose');

var Schema = mongoose.Schema,
    ObjectId = Schema.ObjectId;
var Schema_Product = new Schema({
    categoryId  : ObjectId, // a product references a category _id with type ObjectId
    title       : String,
    price       : Number
});

As you can see, it wouldn't make much sense to populate categoryId with a ObjectId.

However, if you do want a nicely named uuid field, mongoose provides virtual properties that allow you to proxy (reference) a field.

Check it out:

var mongoose = require('mongoose');

var Schema = mongoose.Schema,
    ObjectId = Schema.ObjectId;
var Schema_Category = new Schema({
    title       : String,
    sortIndex   : String
});

Schema_Category.virtual('categoryId').get(function() {
    return this._id;
});

So now, whenever you call category.categoryId, mongoose just returns the _id instead.

You can also create a "set" method so that you can set virtual properties, check out this link for more info

In it's simplest form, use the answer of Georg Fritzsche

For a bit advanced, you can use this,

QString QString::arg ( int a, int fieldWidth = 0, int base = 10, const QChar & fillChar = QLatin1Char( ' ' ) ) const

Get the documentation and an example here..

dovers gives us his great answer and based on it you can try use it like

public static class CellDataFormat
{
        public static string General { get { return "General"; } }
        public static string Number { get { return "0"; } }

        // Your custom format 
        public static string NumberDotTwoDigits { get { return "0.00"; } }

        public static string Currency { get { return "$#,##0.00;[Red]$#,##0.00"; } }
        public static string Accounting { get { return "_($* #,##0.00_);_($* (#,##0.00);_($* \" - \"??_);_(@_)"; } }
        public static string Date { get { return "m/d/yy"; } }
        public static string Time { get { return "[$-F400] h:mm:ss am/pm"; } }
        public static string Percentage { get { return "0.00%"; } }
        public static string Fraction { get { return "# ?/?"; } }
        public static string Scientific { get { return "0.00E+00"; } }
        public static string Text { get { return "@"; } }
        public static string Special { get { return ";;"; } }
        public static string Custom { get { return "#,##0_);[Red](#,##0)"; } }
}

1. Go to the home folder and edit .profile

2. Place the following line at the end

   export LD_LIBRARY_PATH=<your path>

3. Save and Exit.

4. Execute this command

   sudo ldconfig

Have a look at: https://developers.google.com/accounts/docs/OAuth2UserAgent#handlingtheresponse

It says:

Other parameters included in the response include expires_in and token_type. These parameters describe the lifetime of the token in seconds...

DataTable dt = new DataTable(); 

DataRow[] dr = (DataTable)dsData.Tables[0].Select("Some Criteria");

dt.Rows.Add(dr);

This works the best for me:

.noSelect:hover {
  background-color: white;
}

You can use a generated id and name everytime, which is different, so the browser cannot remember this text-field and will fail to suggest some values.

This is at least the cross browser safe alternative, but I would recommend to go with the answer from RobertsonM (autocomplete="off").

I build the logic without using any built-in methods, please let me know any optimization or modifications. I tested in JS editor it is working fine.

var myArray = [
            {name: 'deepak', place: 'bangalore'},
            {name: 'alok', place: 'berhampur'},
            {name: 'chirag', place: 'bangalore'},
            {name: 'chandan', place: 'mumbai'},

        ];
        var toRemove = [

            {name: 'chirag', place: 'bangalore'},
            {name: 'deepak', place: 'bangalore'},
            /*{name: 'chandan', place: 'mumbai'},*/
            /*{name: 'alok', place: 'berhampur'},*/


        ];
        var tempArr = [];
        for( var i=0 ; i < myArray.length; i++){
            for( var j=0; j<toRemove.length; j++){
                var toRemoveObj = toRemove[j];
                if(myArray[i] && (myArray[i].name === toRemove[j].name)) {
                    break;
                }else if(myArray[i] && (myArray[i].name !== toRemove[j].name)){
                        var fnd = isExists(tempArr,myArray[i]);
                        if(!fnd){
                            var idx = getIdex(toRemove,myArray[i])
                            if (idx === -1){
                                tempArr.push(myArray[i]);
                            }

                        }

                    }

                }
        }
        function isExists(source,item){
            var isFound = false;
            for( var i=0 ; i < source.length; i++){
                var obj = source[i];
                if(item && obj && obj.name === item.name){
                    isFound = true;
                    break;
                }
            }
            return isFound;
        }
        function getIdex(toRemove,item){
            var idex = -1;
            for( var i=0 ; i < toRemove.length; i++){
                var rObj =toRemove[i];
                if(rObj && item && rObj.name === item.name){
                    idex=i;
                    break;
                }
            }
            return idex;
        }

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

Wont the below basic approach doesn't suffice your requirements?

HTML Code having a div

<div id="mydiv" onscroll='myMethod();'>

JS will have below code

function myMethod(){ alert(1); }

import com.sun.org.apache.xml.internal.serializer.OutputPropertiesFactory

transformer.setOutputProperty(OutputPropertiesFactory.S_KEY_INDENT_AMOUNT, "2");

If the arguments are filenames to be read from, use the diamond (<>) operator to get at their contents:

while (my $line = <>) {
  process_line($line);
}

If the arguments are options/switches, use GetOpt::Std or GetOpt::Long, as already shown by slavy13.myopenid.com.

On the off chance that they're something else, you can access them either by walking through @ARGV explicitly or with the shift command:

while (my $arg = shift) {
  print "Found argument $arg\n";
}

(Note that doing this with shift will only work if you are outside of all subs. Within a sub, it will retrieve the list of arguments passed to the sub rather than those passed to the program.)

First, all collections in .NET implement IEnumerable.

Second, a lot of the collections are duplicates because generics were added in version 2.0 of the framework.

So, although the generic collections likely add features, for the most part:

• List is a generic implementation of ArrayList.
• Dictionary is a generic implementation of Hashtable

Arrays are a fixed size collection that you can change the value stored at a given index.

SortedDictionary is an IDictionary that is sorted based on the keys. SortedList is an IDictionary that is sorted based on a required IComparer.

So, the IDictionary implementations (those supporting KeyValuePairs) are: * Hashtable * Dictionary * SortedList * SortedDictionary

Another collection that was added in .NET 3.5 is the Hashset. It is a collection that supports set operations.

Also, the LinkedList is a standard linked-list implementation (the List is an array-list for faster retrieval).

size_t is returned by various libraries to indicate that the size of that container is non-zero. You use it when you get once back :0

However, in the your example above looping on a size_t is a potential bug. Consider the following:

for (size_t i = thing.size(); i >= 0; --i) {
  // this will never terminate because size_t is a typedef for
  // unsigned int which can not be negative by definition
  // therefore i will always be >= 0
  printf("the never ending story. la la la la");
}

the use of unsigned integers has the potential to create these types of subtle issues. Therefore imho I prefer to use size_t only when I interact with containers/types that require it.

Simple solution

<TextView
  android:layout_width="match_parent"
  android:layout_height="1dp"
  android:background="#c0c0c0"
  android:id="@+id/your_id"
  android:layout_marginTop="16dp" 
  android:layout_below="@+id/Id_of__view_present_above"
/>

You will have to define the functions inside your header file.
You cannot separate definition of template functions in to the source file and declarations in to header file.

When a template is used in a way that triggers its intstantation, a compiler needs to see that particular templates definition. This is the reason templates are often defined in the header file in which they are declared.

Reference:
C++03 standard, § 14.7.2.4:

The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.

EDIT:
To clarify the discussion on the comments:
Technically, there are three ways to get around this linking problem:

• To move the definition to the .h file
• Add explicit instantiations in the .cpp file.
• #include the .cpp file defining the template at the .cpp file using the template.

Each of them have their pros and cons,

Moving the defintions to header files may increase the code size(modern day compilers can avoid this) but will increase the compilation time for sure.

Using the explicit instantiation approach is moving back on to traditional macro like approach.Another disadvantage is that it is necessary to know which template types are needed by the program. For a simple program this is easy but for complicated program this becomes difficult to determine in advance.

While including cpp files is confusing at the same time shares the problems of both above approaches.

I find first method the easiest to follow and implement and hence advocte using it.

Spring Data is a convenience library on top of JPA that abstracts away many things and brings Spring magic (like it or not) to the persistence store access. It is primarily used for working with relational databases. In short, it allows you to declare interfaces that have methods like findByNameOrderByAge(String name); that will be parsed in runtime and converted into appropriate JPA queries.

Its placement atop of JPA makes its use tempting for:

1. Rookie developers who don't know SQL or know it badly. This is a recipe for disaster but they can get away with it if the project is trivial.

2. Experienced engineers who know what they do and want to spindle up things fast. This might be a viable strategy (but read further).

From my experience with Spring Data, its magic is too much (this is applicable to Spring in general). I started to use it heavily in one project and eventually hit several corner cases where I couldn't get the library out of my way and ended up with ugly workarounds. Later I read other users' complaints and realized that these issues are typical for Spring Data. For example, check this issue that led to hours of investigation/swearing:

 public TourAccommodationRate createTourAccommodationRate(
        @RequestBody TourAccommodationRate tourAccommodationRate
    ) {
        if (tourAccommodationRate.getId() != null) {
            throw new BadRequestException("id MUST NOT be specified in a body during entry creation");
        }

        // This is an ugly hack required for the Room slim model to work. The problem stems from the fact that
        // when we send a child entity having the many-to-many (M:N) relation to the containing entity, its
        // information is not fetched. As a result, we get NPEs when trying to access all but its Id in the
        // code creating the corresponding slim model. By detaching the entity from the persistence context we
        // force the ORM to re-fetch it from the database instead of taking it from the cache

        tourAccommodationRateRepository.save(tourAccommodationRate);
        entityManager.detach(tourAccommodationRate);
        return tourAccommodationRateRepository.findOne(tourAccommodationRate.getId());
    }

I ended up going lower level and started using JDBI - a nice library with just enough "magic" to save you from the boilerplate. With it, you have complete control over SQL queries and almost never have to fight the library.

If your email address is '[email protected]', try changing the createDirectoryEntry() as below.

XYZ is an optional parameter if it exists in mydomain directory

static DirectoryEntry createDirectoryEntry()
{
    // create and return new LDAP connection with desired settings
    DirectoryEntry ldapConnection = new DirectoryEntry("myname.mydomain.com");
    ldapConnection.Path = "LDAP://OU=Users, OU=XYZ,DC=mydomain,DC=com";
    ldapConnection.AuthenticationType = AuthenticationTypes.Secure;
    return ldapConnection;
}

This will basically check for com -> mydomain -> XYZ -> Users -> abcd

The main function looks as below:

try
{
    username = "Firstname LastName"
    DirectoryEntry myLdapConnection = createDirectoryEntry();
    DirectorySearcher search = new DirectorySearcher(myLdapConnection);
    search.Filter = "(cn=" + username + ")";
    ....    

The best would be to do this server-side or wrap the currency symbols in an element you can select before returning it to the browser, however if neither is an option, you can select all text nodes within the body and do the replace on them. Below i'm doing this using a plugin i wrote 2 years ago that was meant for highlighting text. What i'm doing is finding all occurrences of € and wrapping it in a span with the class currency-symbol, then i'm replacing the text of those spans.

Demo

(function($){

    $.fn.highlightText = function () {
        // handler first parameter
        // is the first parameter a regexp?
        var re,
            hClass,
            reStr,
            argType = $.type(arguments[0]),
            defaultTagName = $.fn.highlightText.defaultTagName;

        if ( argType === "regexp" ) {
            // first argument is a regular expression
            re = arguments[0];
        }       
        // is the first parameter an array?
        else if ( argType === "array" ) {
            // first argument is an array, generate
            // regular expression string for later use
            reStr = arguments[0].join("|");
        }       
        // is the first parameter a string?
        else if ( argType === "string" ) {
            // store string in regular expression string
            // for later use
            reStr = arguments[0];
        }       
        // else, return out and do nothing because this
        // argument is required.
        else {
            return;
        }

        // the second parameter is optional, however,
        // it must be a string or boolean value. If it is 
        // a string, it will be used as the highlight class.
        // If it is a boolean value and equal to true, it 
        // will be used as the third parameter and the highlight
        // class will default to "highlight". If it is undefined,
        // the highlight class will default to "highlight" and 
        // the third parameter will default to false, allowing
        // the plugin to match partial matches.
        // ** The exception is if the first parameter is a regular
        // expression, the third parameter will be ignored.
        argType = $.type(arguments[1]);
        if ( argType === "string" ) {
            hClass = arguments[1];
        }
        else if ( argType === "boolean" ) {
            hClass = "highlight";
            if ( reStr ) {
                reStr = "\\b" + reStr + "\\b";
            }
        }
        else {
            hClass = "highlight";
        }

        if ( arguments[2] && reStr ) {
            reStr = reStr = "\\b" + reStr + "\\b";
        } 

        // if re is not defined ( which means either an array or
        // string was passed as the first parameter ) create the
        // regular expression.
        if (!re) {
            re = new RegExp( "(" + reStr + ")", "ig" );
        }

        // iterate through each matched element
        return this.each( function() {
            // select all contents of this element
            $( this ).find( "*" ).andSelf().contents()

            // filter to only text nodes that aren't already highlighted
            .filter( function () {
                return this.nodeType === 3 && $( this ).closest( "." + hClass ).length === 0;
            })

            // loop through each text node
            .each( function () {
                var output;
                output = this.nodeValue
                    .replace( re, "<" + defaultTagName + " class='" + hClass + "'>$1</" + defaultTagName +">" );
                if ( output !== this.nodeValue ) {
                    $( this ).wrap( "<p></p>" ).parent()
                        .html( output ).contents().unwrap();
                }
            });
        });
    };

    $.fn.highlightText.defaultTagName = "span";

})( jQuery );

$("body").highlightText("€","currency-symbol");
$("span.currency-symbol").text("$");

Here is simple way to handle the above.

In Html Template we put Post

<form action="/useradd/addnewroute/" method="post" id="login-form">{% csrf_token %}

<!-- add details of form here-->
<form>
<form action="/useradd/addarea/" method="post" id="login-form">{% csrf_token %}

<!-- add details of form here-->

<form>

In View

   def addnewroute(request):
      if request.method == "POST":
         # do something



  def addarea(request):
      if request.method == "POST":
         # do something

In URL Give needed info like

urlpatterns = patterns('',
url(r'^addnewroute/$', views.addnewroute, name='addnewroute'),
url(r'^addarea/', include('usermodules.urls')),

A very simple way:

/** Save the position **/
int currentPosition = listView.getFirstVisiblePosition();

//Here u should save the currentPosition anywhere

/** Restore the previus saved position **/
listView.setSelection(savedPosition);

The method setSelection will reset the list to the supplied item. If not in touch mode the item will actually be selected if in touch mode the item will only be positioned on screen.

A more complicated approach:

listView.setOnScrollListener(this);

//Implements the interface:
@Override
public void onScroll(AbsListView view, int firstVisibleItem,
            int visibleItemCount, int totalItemCount) {
    mCurrentX = view.getScrollX();
    mCurrentY = view.getScrollY();
}

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {

}

//Save anywere the x and the y

/** Restore: **/
listView.scrollTo(savedX, savedY);

If you have a block of code+html that appears on several pages and is sort of independent of that page (say a block of latest news items), you could copy/paste the code to every page.

It is however better to put that code in its own block and just include that block on every page that needs it. That "block" is an ascx file.

I haven't heard about progress with Copy-Item. If you don't want to use any external tool, you can experiment with streams. The size of buffer varies, you may try different values (from 2kb to 64kb).

function Copy-File {
    param( [string]$from, [string]$to)
    $ffile = [io.file]::OpenRead($from)
    $tofile = [io.file]::OpenWrite($to)
    Write-Progress -Activity "Copying file" -status "$from -> $to" -PercentComplete 0
    try {
        [byte[]]$buff = new-object byte[] 4096
        [long]$total = [int]$count = 0
        do {
            $count = $ffile.Read($buff, 0, $buff.Length)
            $tofile.Write($buff, 0, $count)
            $total += $count
            if ($total % 1mb -eq 0) {
                Write-Progress -Activity "Copying file" -status "$from -> $to" `
                   -PercentComplete ([long]($total * 100 / $ffile.Length))
            }
        } while ($count -gt 0)
    }
    finally {
        $ffile.Dispose()
        $tofile.Dispose()
        Write-Progress -Activity "Copying file" -Status "Ready" -Completed
    }
}

I've found nosklo's answer very extensive and useful! For those, like myself, who might find accessing the raw request data directly also useful, I would like to add the way to do that:

import os, sys

# the query string, which contains the raw GET data
# (For example, for http://example.com/myscript.py?a=b&c=d&e
# this is "a=b&c=d&e")
os.getenv("QUERY_STRING")

# the raw POST data
sys.stdin.read()

I found an easy way. you can try to test it.

Just follow below steps as I show:

First, in terminal, enter

vim ~/.zshrc

add

source ~/.bash_profile

into .zshrc file

and then in terminal, enter

source ~/.zshrc

Congratulation for you.

You can use NGBindHTML or NGbindHtmlUnsafe this will not escape the html content of your model.

http://jsfiddle.net/n9rQr/

<div ng-app ng-controller="MyCtrl">
    <ul>
    <li ng-repeat=" opt in opts"  ng-bind-html-unsafe="opt.text">
        {{ opt.text }}
    </li>
    </ul>

    <p>{{opt}}</p>
</div>

This works, anyway you should be very careful when using unsanitized html content, you should really trust the source of the content.

It's called an initialization list. An initializer list is how you pass arguments to your member variables' constructors and for passing arguments to the parent class's constructor.

If you use = to assign in the constructor body, first the default constructor is called, then the assignment operator is called. This is a bit wasteful, and sometimes there's no equivalent assignment operator.

This article helped me alot figuring out why it wasn't working for me either. It give me a lesson to think of the webpage loading and how angular 2 interacts as a timeline and not just the point in time i'm thinking of. I didn't see anyone else mention this point, so I will...

The reason the *ngIf is needed because it will try to check the length of that variable before the rest of the OnInit stuff happens, and throw the "length undefined" error. So thats why you add the ? because it won't exist yet, but it will soon.

You can use the INSERT ... SELECT statement to get the MAX()+1 value and insert at the same time:

INSERT INTO 
customers( customer_id, firstname, surname )
SELECT MAX( customer_id ) + 1, 'jim', 'sock' FROM customers;

^{Note: You need to drop the VALUES from your INSERT and make sure the SELECT selected fields match the INSERT declared fields.}

I know this is very old, but none of these answers helped me, so I'm adding my answer. This, like @yichengliu's answer, uses the Pseudo ::after element.

}

Fiddle

If you decide to change the X of the drop shadow (first pixel measurement of the drop-shadow or box-shadow), changing the width will help so it doesn't look like there is a white gap between the div and the shadow.

If you decide to change the Y of the drop shadow (second pixel measurement of the drop-shadow or box-shadow), changing the height will help for the same reason as above.

This will give you names and table count of all the databases in you mysql

SELECT TABLE_SCHEMA,COUNT(*) FROM information_schema.tables group by TABLE_SCHEMA;

You can bind to all of the radio buttons at once by name:

$('input[name=someRadioGroup]:radio').change(...);

Synchronized simply means that multiple threads if associated with single object can prevent dirty read and write if synchronized block is used on particular object. To give you more clarity , lets take an example :

class MyRunnable implements Runnable {
    int var = 10;
    @Override
    public void run() {
        call();
    }

    public void call() {
        synchronized (this) {
            for (int i = 0; i < 4; i++) {
                var++;
                System.out.println("Current Thread " + Thread.currentThread().getName() + " var value "+var);
            }
        }
    }
}

public class MutlipleThreadsRunnable {
    public static void main(String[] args) {
        MyRunnable runnable1 = new MyRunnable();
        MyRunnable runnable2 = new MyRunnable();
        Thread t1 = new Thread(runnable1);
        t1.setName("Thread -1");
        Thread t2 = new Thread(runnable2);
        t2.setName("Thread -2");
        Thread t3 = new Thread(runnable1);
        t3.setName("Thread -3");
        t1.start();
        t2.start();
        t3.start();
    }
}

We've created two MyRunnable class objects , runnable1 being shared with thread 1 and thread 3 & runnable2 being shared with thread 2 only. Now when t1 and t3 starts without synchronized being used , PFB output which suggest that both threads 1 and 3 simultaneously affecting var value where for thread 2 , var has its own memory.

Without Synchronized keyword

    Current Thread Thread -1 var value 11
    Current Thread Thread -2 var value 11
    Current Thread Thread -2 var value 12
    Current Thread Thread -2 var value 13
    Current Thread Thread -2 var value 14
    Current Thread Thread -1 var value 12
    Current Thread Thread -3 var value 13
    Current Thread Thread -3 var value 15
    Current Thread Thread -1 var value 14
    Current Thread Thread -1 var value 17
    Current Thread Thread -3 var value 16
    Current Thread Thread -3 var value 18

Using Synchronzied, thread 3 waiting for thread 1 to complete in all scenarios. There are two locks acquired , one on runnable1 shared by thread 1 and thread 3 and another on runnable2 shared by thread 2 only.

Current Thread Thread -1 var value 11
Current Thread Thread -2 var value 11
Current Thread Thread -1 var value 12
Current Thread Thread -2 var value 12
Current Thread Thread -1 var value 13
Current Thread Thread -2 var value 13
Current Thread Thread -1 var value 14
Current Thread Thread -2 var value 14
Current Thread Thread -3 var value 15
Current Thread Thread -3 var value 16
Current Thread Thread -3 var value 17
Current Thread Thread -3 var value 18

Try this:

{[0-9]{1,3}:[0-9]{1,3}}

The {1,3} means "match between 1 and 3 of the preceding characters".

You can also use a .vbs file to do specific timeouts:

The code below creates the .vbs file. Put this near the top of you rbatch code:

echo WScript.sleep WScript.Arguments(0) >"%cd%\sleeper.vbs"

The code below then opens the .vbs and specifies how long to wait for:

start /WAIT "" "%cd%\sleeper.vbs" "1000"

In the above code, the "1000" is the value of time delay to be sent to the .vbs file in milliseconds, for example, 1000 ms = 1 s. You can alter this part to be however long you want.

The code below deletes the .vbs file after you are done with it. Put this at the end of your batch file:

del /f /q "%cd%\sleeper.vbs"

And here is the code all together so it's easy to copy:

echo WScript.sleep WScript.Arguments(0) >"%cd%\sleeper.vbs"
start /WAIT "" "%cd%\sleeper.vbs" "1000"
del /f /q "%cd%\sleeper.vbs"

There isn't direct support for COUNT(DISTINCT {x})), but you can simulate it from an IGrouping<,> (i.e. what group by returns); I'm afraid I only "do" C#, so you'll have to translate to VB...

 select new
 {
     Foo= grp.Key,
     Bar= grp.Select(x => x.SomeField).Distinct().Count()
 };

Here's a Northwind example:

    using(var ctx = new DataClasses1DataContext())
    {
        ctx.Log = Console.Out; // log TSQL to console
        var qry = from cust in ctx.Customers
                  where cust.CustomerID != ""
                  group cust by cust.Country
                  into grp
                  select new
                  {
                      Country = grp.Key,
                      Count = grp.Select(x => x.City).Distinct().Count()
                  };

        foreach(var row in qry.OrderBy(x=>x.Country))
        {
            Console.WriteLine("{0}: {1}", row.Country, row.Count);
        }
    }

The TSQL isn't quite what we'd like, but it does the job:

SELECT [t1].[Country], (
    SELECT COUNT(*)
    FROM (
        SELECT DISTINCT [t2].[City]
        FROM [dbo].[Customers] AS [t2]
        WHERE ((([t1].[Country] IS NULL) AND ([t2].[Country] IS NULL)) OR (([t1]
.[Country] IS NOT NULL) AND ([t2].[Country] IS NOT NULL) AND ([t1].[Country] = [
t2].[Country]))) AND ([t2].[CustomerID] <> @p0)
        ) AS [t3]
    ) AS [Count]
FROM (
    SELECT [t0].[Country]
    FROM [dbo].[Customers] AS [t0]
    WHERE [t0].[CustomerID] <> @p0
    GROUP BY [t0].[Country]
    ) AS [t1]
-- @p0: Input NVarChar (Size = 0; Prec = 0; Scale = 0) []
-- Context: SqlProvider(Sql2008) Model: AttributedMetaModel Build: 3.5.30729.1

The results, however, are correct- verifyable by running it manually:

        const string sql = @"
SELECT c.Country, COUNT(DISTINCT c.City) AS [Count]
FROM Customers c
WHERE c.CustomerID != ''
GROUP BY c.Country
ORDER BY c.Country";
        var qry2 = ctx.ExecuteQuery<QueryResult>(sql);
        foreach(var row in qry2)
        {
            Console.WriteLine("{0}: {1}", row.Country, row.Count);
        }

With definition:

class QueryResult
{
    public string Country { get; set; }
    public int Count { get; set; }
}

Try this:

select * from your_table
where date >= '2020-10-01'  

Ctrl + Shift + P and select Terminal:clear

// Earlier in your code
mysql_connect();
set_a_flag_that_db_is_connected();

// Later....
if (flag_is_set())
 mysql_connect(....);

var str = "123, 124, 234,252";
var arr = str.split(",");
for(var i=0;i<arr.length;i++) {
    arr[i] = ++arr[i];
}

Another way to control this setting is by using an undocumented registry key AutoDetect=0 mentioned on this blog post:

Registry Key : HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\

DWORD AutoDetect = 0 or 1

So the .reg file to turn it off would look like:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"AutoDetect"=dword:00000000

My dirty and may tiniest using String.replaceAll:

.replaceAll("^.*\\.(.*)$", "$1")

Note that first * is greedy so it will grab most possible characters as far as it can and then just last dot and file extension will be left.

Activator.CreateInstance() returns an object, which doesn't have an Output method.

It looks like you come from dynamic programming languages? C# is definetly not that, and what you are trying to do will be difficult.

Since you are loading a specific dll from a specific location, maybe you just want to add it as a reference to your console application?

If you absolutely want to load the assembly via Assembly.Load, you will have to go via reflection to call any members on c

Something like type.GetMethod("Output").Invoke(c, null); should do it.

For the parent:

display: flex;

For children:

align-items: stretch;

You should add some prefixes, check caniuse.

If you look to run a method on ngOnInit you could do something like this:

import this 2 libraries from RXJS:

import {Observable} from 'rxjs/Rx';
import {Subscription} from "rxjs";

Then declare timer and private subscription, example:

timer= Observable.timer(1000,1000); // 1 second for 2 seconds (2000,1000) etc
private subscription: Subscription;

Last but not least run method when timer stops

ngOnInit() {
  this.subscription = this.timer.subscribe(ticks=> {
    this.populatecombobox();  //example calling a method that populates a combobox
    this.subscription.unsubscribe();  //you need to unsubscribe or it will run infinite times
  });
}

That's all, Angular 5

Simple:

if ( $name eq 'tom' && $password eq '123!'
    || $name eq 'frank' && $password eq '321!'
) {

(use the high-precedence && and || in expressions, reserving and and or for flow control, to avoid common precedence errors)

Better:

my %password = (
    'tom' => '123!',
    'frank' => '321!',
);

if ( exists $password{$name} && $password eq $password{$name} ) {

This is basically available in a 'protected' attribute of the Enum class:

list(Color._value2member_map_.keys())

In linux,

find project_directory_name_here -type d -exec chmod 755 {} \;
find project_directory_name_here -type f -exec chmod 644 {} \;

It will replace all files and folder permission of project_directory_name_here and its inside stuff.

In my case removing/adding that assembly worked.

A Subscription is an object that represents a disposable resource, usually the execution of an Observable. A Subscription has one important method, unsubscribe, that takes no argument and just disposes of the resource held by the subscription.

import { interval } from 'rxjs';

const observable = interval(1000);
const subscription = observable.subscribe(a=> console.log(a));

/** This cancels the ongoing Observable execution which
was started by calling subscribe with an Observer.*/

subscription.unsubscribe();

A Subscription essentially just has an unsubscribe() function to release resources or cancel Observable executions.

import { interval } from 'rxjs';

const observable1 = interval(400);
const observable2 = interval(300);

const subscription = observable1.subscribe(x => console.log('first: ' + x));
const childSubscription = observable2.subscribe(x => console.log('second: ' + x));

subscription.add(childSubscription);

setTimeout(() => {
// It unsubscribes BOTH subscription and childSubscription
subscription.unsubscribe();
}, 1000);

According to the official documentation, Angular should unsubscribe for you, but apparently, there is a bug.

javascript uses dynamic arrays, no need to declare the size beforehand

you can push and shift to arrays as many times as you want, javascript will handle allocation and stuff for you

Today I designed this Ant MacroDef for the same problem as yours :

    <!--

Use it in your build file with :

    <TypeScriptCompileDir
        src="${src-js.dir}"
        out="${release-file-path}"
        module="amd"
    />

It is used in the project PureMVC for TypeScript I'm working on at the time using Webstorm.

The issue here is that JSON, as a format, is generally parsed in full and then handled in-memory, which for such a large amount of data is clearly problematic.

The solution to this is to work with the data as a stream - reading part of the file, working with it, and then repeating.

The best option appears to be using something like ijson - a module that will work with JSON as a stream, rather than as a block file.

Edit: Also worth a look - kashif's comment about json-streamer and Henrik Heino's comment about bigjson.

try running after changing file name from '-' to `_'

for eg: .\my_app\my_fle.bat

instead of .\\my-app\my-fle.bat

Or

cd my_app  
 .\my_file.bat

Try to put the following to the ~/.gitconfig file:

[http]
    proxy = http://proxy:8080
[https]
    proxy = http://proxy:8080
[url "https://"]
    insteadOf = git://

This is almost certainly going to be true given that SSL requires an extra step of encryption that simply isn't required by non-SLL HTTP.

There are several ways.

1. awk has a system() function that will run a shell command:

   system("cmd")

2. You can print to a pipe:

   print "blah" | "cmd"

3. You can have awk construct commands, and pipe all the output to the shell:

   awk 'some script' | sh

Yes it is, there have to be boolean expresion after IF. Here you have a direct link. I hope it helps. GL!

You might want to take a look this:

HotSwap support: the object-oriented architecture of the Java HotSpot VM enables advanced features such as on-the-fly class redefinition, or "HotSwap". This feature provides the ability to substitute modified code in a running application through the debugger APIs. HotSwap adds functionality to the Java Platform Debugger Architecture, enabling a class to be updated during execution while under the control of a debugger. It also allows profiling operations to be performed by hotswapping in versions of methods in which profiling code has been inserted.

For the moment, this only allows for newly compiled method body to be redeployed without restarting the application. All you have to do is to run it with a debugger. I tried it in Eclipse and it works splendidly.

Also, as Emmanuel Bourg mentioned in his answer (JEP 159), there is hope to have support for the addition of supertypes and the addition and removal of methods and fields.

Update (2017/01/05):

GitHub has published an update that allows you now to search within commit messages from within their UI. See blog post for more information.

I had the same question and contacted someone GitHub yesterday:

Since they switched their search engine to Elasticsearch it's not possible to search for commit messages using the GitHub UI. But that feature is on the team's wishlist.

Unfortunately there's no release date for that function right now.

You can use below code to find out principal (user email who logged in)

  org.opensaml.saml2.core.impl.NameIDImpl principal =  
  (NameIDImpl) SecurityContextHolder.getContext().getAuthentication().getPrincipal();

  String email = principal.getValue();

This code is written on top of SAML.

I searched and found the solution in the following URL is better.

http://www.tutorialrepublic.com/faq/call-a-function-after-some-time-in-jquery.php

It worth to try.

It adds your given function to the queue of functions to be executed on the matched element which is currently this.

 $(this).delay(1000).queue(function() {

     // your Code | Function here
     
     $(this).dequeue();
  
  });

and then execute the next function on the queue for the matched element(s) which is currently this again.

-- EDIT [ POSSIBLE EXPLANATION FOR THE DEQUEUE COMMAND ]

Take a look at the command

We command the jQuery engine to add a function in internal queue and then after a specific amount of time we command it to call that function, BUT so far we never told it to dequeue it from engine. Right?! And then after every thing is done we are dequeue it from jQuery engine manually. I hope the explanation could help.

I solved this problem instantiating a new Date object in node.js:...

In Javascript, send the Date().toISOString() to nodejs:...

var start_date = new Date(2012, 01, 03, 8, 30);

$.ajax({
    type: 'POST',
    data: { start_date: start_date.toISOString() },
    url: '/queryScheduleCollection',
    dataType: 'JSON'
}).done(function( response ) { ... });

Then use the ISOString to create a new Date object in nodejs:..

exports.queryScheduleCollection = function(db){
    return function(req, res){

        var start_date = new Date(req.body.start_date);

        db.collection('schedule_collection').find(
            { start_date: { $gte: start_date } }
        ).toArray( function (err,d){
            ...
            res.json(d)
        })
    }
};

Note: I'm using Express and Mongoskin.

Try something like this:

foreach (ListItem listItem in YrChkBox.Items)
{
    if (listItem.Selected)
    { 
       //do some work 
    }
    else 
    { 
      //do something else 
    }
}

For this problem, as for many others involving non-trivial left joins such as left-joining on inner-joined tables, I find it convenient and somewhat more readable to split the query with a with clause. In your example,

with settings_for_char as (
  select setting_id, value from character_settings where character_id = 1
)
select
  settings.*,
  settings_for_char.value
from
  settings
  left join settings_for_char on settings_for_char.setting_id = settings.id;

SELECT COUNT(*) FROM bla WHERE Position = 'Manager'

$('tbody').find('tr:visible').hightlight(myArray[i]);

This works for 4.0.

<nav class="navbar navbar-expand-sm fixed-top navbar-light">
or
<nav class="navbar navbar-expand-lg fixed-top navbar-dark">

key item is fixed-top, otherwise, white or default page background is displayed even if there is a image top. navbar-light gives dark letters, navbar-dark shows light text.

Or with a constructor & linq with Select:

public class TargetType {
  public string Prop1 {get;set;}
  public string Prop1 {get;set;}

  // Constructor
  public TargetType(OrigType origType) {
    Prop1 = origType.Prop1;
    Prop2 = origType.Prop2;
  }
}

var origList = new List<OrigType>();
var targetList = origList.Select(s=> new TargetType(s)).ToList();  

The Linq line is more soft! ;-)

Bash allow u to use =~ to test if the substring is contained. Ergo, the use of negate will allow to test the opposite.

fullstring="123asdf123"
substringA=asdf
substringB=gdsaf
# test for contains asdf, gdsaf and for NOT CONTAINS gdsaf 
[[ $fullstring =~ $substring ]] && echo "found substring $substring in $fullstring"
[[ $fullstring =~ $substringB ]] && echo "found substring $substringB in $fullstring" || echo "failed to find"
[[ ! $fullstring =~ $substringB ]] && echo "did not find substring $substringB in $fullstring"

For guys like me, who aren't minimalistic, there is a PECL extension called "intl". I use it for idn conversion since it works way better than the "idn" extension and some other n1 classes like "IntlDateFormatter".

Well, what I want to say is, the "intl" extension has a class called "IntlCalendar" which can handle many international countries (e.g. in Saudi Arabia, sunday is not a weekend day). The IntlCalendar has a method IntlCalendar::isWeekend for that. Maybe you guys give it a shot, I like that "it works for almost every country" fact on these intl-classes.

EDIT: Not quite sure but since PHP 5.5.0, the intl extension is bundled with PHP (--enable-intl).

Just assign it to the .columns attribute:

>>> df = pd.DataFrame({'$a':[1,2], '$b': [10,20]})
>>> df
   $a  $b
0   1  10
1   2  20

>>> df.columns = ['a', 'b']
>>> df
   a   b
0  1  10
1  2  20

Try this:

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rel_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ImageView
    android:id="@+id/ImageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src=//source of image />

<TextView
    android:id="@+id/ImageViewText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@id/ImageView"
    android:layout_alignTop="@id/ImageView"
    android:layout_alignRight="@id/ImageView"
    android:layout_alignBottom="@id/ImageView"
    android:text=//u r text here
    android:gravity="center"
    />

Hope this could help you.

Case 1 : Yes, this works fine.

Case 2 : This will fail with the error ORA-01441 : cannot decrease column length because some value is too big.

Assuming your example text is representative of all the text, one line would consume about 75 bytes on my machine:

In [3]: sys.getsizeof('usedfor zipper fasten_coat')
Out[3]: 75

Doing some rough math:

75 bytes * 8,000,000 lines / 1024 / 1024 = ~572 MB

So roughly 572 meg to store the strings alone for one of these files. Once you start adding in additional, similarly structured and sized files, you'll quickly approach your virtual address space limits, as mentioned in @ShadowRanger's answer.

If upgrading your python isn't feasible for you, or if it only kicks the can down the road (you have finite physical memory after all), you really have two options: write your results to temporary files in-between loading in and reading the input files, or write your results to a database. Since you need to further post-process the strings after aggregating them, writing to a database would be the superior approach.

Try the following enum :

enum Color {
    //Color end string, color reset
    RESET("\033[0m"),

    // Regular Colors. Normal color, no bold, background color etc.
    BLACK("\033[0;30m"),    // BLACK
    RED("\033[0;31m"),      // RED
    GREEN("\033[0;32m"),    // GREEN
    YELLOW("\033[0;33m"),   // YELLOW
    BLUE("\033[0;34m"),     // BLUE
    MAGENTA("\033[0;35m"),  // MAGENTA
    CYAN("\033[0;36m"),     // CYAN
    WHITE("\033[0;37m"),    // WHITE

    // Bold
    BLACK_BOLD("\033[1;30m"),   // BLACK
    RED_BOLD("\033[1;31m"),     // RED
    GREEN_BOLD("\033[1;32m"),   // GREEN
    YELLOW_BOLD("\033[1;33m"),  // YELLOW
    BLUE_BOLD("\033[1;34m"),    // BLUE
    MAGENTA_BOLD("\033[1;35m"), // MAGENTA
    CYAN_BOLD("\033[1;36m"),    // CYAN
    WHITE_BOLD("\033[1;37m"),   // WHITE

    // Underline
    BLACK_UNDERLINED("\033[4;30m"),     // BLACK
    RED_UNDERLINED("\033[4;31m"),       // RED
    GREEN_UNDERLINED("\033[4;32m"),     // GREEN
    YELLOW_UNDERLINED("\033[4;33m"),    // YELLOW
    BLUE_UNDERLINED("\033[4;34m"),      // BLUE
    MAGENTA_UNDERLINED("\033[4;35m"),   // MAGENTA
    CYAN_UNDERLINED("\033[4;36m"),      // CYAN
    WHITE_UNDERLINED("\033[4;37m"),     // WHITE

    // Background
    BLACK_BACKGROUND("\033[40m"),   // BLACK
    RED_BACKGROUND("\033[41m"),     // RED
    GREEN_BACKGROUND("\033[42m"),   // GREEN
    YELLOW_BACKGROUND("\033[43m"),  // YELLOW
    BLUE_BACKGROUND("\033[44m"),    // BLUE
    MAGENTA_BACKGROUND("\033[45m"), // MAGENTA
    CYAN_BACKGROUND("\033[46m"),    // CYAN
    WHITE_BACKGROUND("\033[47m"),   // WHITE

    // High Intensity
    BLACK_BRIGHT("\033[0;90m"),     // BLACK
    RED_BRIGHT("\033[0;91m"),       // RED
    GREEN_BRIGHT("\033[0;92m"),     // GREEN
    YELLOW_BRIGHT("\033[0;93m"),    // YELLOW
    BLUE_BRIGHT("\033[0;94m"),      // BLUE
    MAGENTA_BRIGHT("\033[0;95m"),   // MAGENTA
    CYAN_BRIGHT("\033[0;96m"),      // CYAN
    WHITE_BRIGHT("\033[0;97m"),     // WHITE

    // Bold High Intensity
    BLACK_BOLD_BRIGHT("\033[1;90m"),    // BLACK
    RED_BOLD_BRIGHT("\033[1;91m"),      // RED
    GREEN_BOLD_BRIGHT("\033[1;92m"),    // GREEN
    YELLOW_BOLD_BRIGHT("\033[1;93m"),   // YELLOW
    BLUE_BOLD_BRIGHT("\033[1;94m"),     // BLUE
    MAGENTA_BOLD_BRIGHT("\033[1;95m"),  // MAGENTA
    CYAN_BOLD_BRIGHT("\033[1;96m"),     // CYAN
    WHITE_BOLD_BRIGHT("\033[1;97m"),    // WHITE

    // High Intensity backgrounds
    BLACK_BACKGROUND_BRIGHT("\033[0;100m"),     // BLACK
    RED_BACKGROUND_BRIGHT("\033[0;101m"),       // RED
    GREEN_BACKGROUND_BRIGHT("\033[0;102m"),     // GREEN
    YELLOW_BACKGROUND_BRIGHT("\033[0;103m"),    // YELLOW
    BLUE_BACKGROUND_BRIGHT("\033[0;104m"),      // BLUE
    MAGENTA_BACKGROUND_BRIGHT("\033[0;105m"),   // MAGENTA
    CYAN_BACKGROUND_BRIGHT("\033[0;106m"),      // CYAN
    WHITE_BACKGROUND_BRIGHT("\033[0;107m");     // WHITE

    private final String code;

    Color(String code) {
        this.code = code;
    }

    @Override
    public String toString() {
        return code;
    }
}

And now we will make a small example:

class RunApp {
    public static void main(String[] args) {

        System.out.print(Color.BLACK_BOLD);
        System.out.println("Black_Bold");
        System.out.print(Color.RESET);

        System.out.print(Color.YELLOW);
        System.out.print(Color.BLUE_BACKGROUND);
        System.out.println("YELLOW & BLUE");
        System.out.print(Color.RESET);

        System.out.print(Color.YELLOW);
        System.out.println("YELLOW");
        System.out.print(Color.RESET);
    }
}

There's a great article from Slava Akhmechet called Functional Programming For The Rest of Us (this was the article that got me into FP btw). Amongst the benefits FP brings, he unorthodoxly emphasizes the following (which I believe contributes to the appeal for software engineers):

• Unit Testing
• Debugging
• Concurrency
• Hot Code Deployment
• Machine Assisted Proofs and Optimizations

And then goes on to discuss the goodness of more traditionally discussed aspects of FP like higher order functions, currying, lazy evaluation, optimization, abstracting control structures (although not discussing monads), infinite data structures, strictness, continuations, pattern matching, closures and so on.

Highly recommended !

Instead of calling /usr/bin/gcc, use /usr/bin/c99. This is the Single-Unix-approved way of invoking a C99 compiler. On an Ubuntu system, this points to a script which invokes gcc after having added the -std=c99 flag, which is precisely what you want.

You don't need to convert to decimal; you can also enter 46 23S, 115 22E. You can add seconds after the minutes, also separated by a space.

Jq now have better way to acces environment variables, you can use env.EMAILI:

projectID=$(cat file.json | jq -r ".resource[] | select(.username==env.EMAILID) | .id")

Please just write a static method somewhere and write:

if( isSizeBetween(orderBean.getFiles(), 0, 5) ){
    // do your stuff 
}

Finally I found solution myself.

I had to annotate enum with @JsonSerialize(using = OrderTypeSerializer.class) and implement custom serializer:

public class OrderTypeSerializer extends JsonSerializer<OrderType> {

  @Override
  public void serialize(OrderType value, JsonGenerator generator,
            SerializerProvider provider) throws IOException,
            JsonProcessingException {

    generator.writeStartObject();
    generator.writeFieldName("id");
    generator.writeNumber(value.getId());
    generator.writeFieldName("name");
    generator.writeString(value.getName());
    generator.writeEndObject();
  }
}

cbind.fill <- function(x, y){
  xrn <- rownames(x)
  yrn <- rownames(y)
  rn <- union(xrn, yrn)
  xcn <- colnames(x)
  ycn <- colnames(y)
  if(is.null(xrn) | is.null(yrn) | is.null(xcn) | is.null(ycn)) 
    stop("NULL rownames or colnames")
  z <- matrix(NA, nrow=length(rn), ncol=length(xcn)+length(ycn))
  rownames(z) <- rn
  colnames(z) <- c(xcn, ycn)
  idx <- match(rn, xrn)
  z[!is.na(idx), 1:length(xcn)] <- x[na.omit(idx),]
  idy <- match(rn, yrn)
  z[!is.na(idy), length(xcn)+(1:length(ycn))] <- y[na.omit(idy),]
  return(z)
}

Use mysqlimport to load a table into the database:

mysqlimport --ignore-lines=1 \
            --fields-terminated-by=, \
            --local -u root \
            -p Database \
             TableName.csv

I found it at http://chriseiffel.com/everything-linux/how-to-import-a-large-csv-file-to-mysql/

To make the delimiter a tab, use --fields-terminated-by='\t'

please try this flower:

/^[a-z0-9\_\.\-]{2,20}\@[a-z0-9\_\-]{2,20}\.[a-z]{2,9}$/.test('[email protected]');

true

Note that the Perldebugger can also be invoked from the scripts shebang line, which is how I mostly use the -x flag you refer to, to debug shell scripts.

#! /usr/bin/perl -d

For me I needed to do something like this to completely remove the borders from the table and all cells. This does not require modifying the HTML at all, which was helpful in my case.

table, tr, td {
    border: none;
}

SELECT (sub)queries return result sets. So you need to use IN, not = in your WHERE clause.

Additionally, as shown in this answer you cannot modify the same table from a subquery within the same query. However, you can either SELECT then DELETE in separate queries, or nest another subquery and alias the inner subquery result (looks rather hacky, though):

DELETE FROM posts WHERE id IN (
    SELECT * FROM (
        SELECT id FROM posts GROUP BY id HAVING ( COUNT(id) > 1 )
    ) AS p
)

Or use joins as suggested by Mchl.

Just for reference, here is a list of all the available properties for a printer ManagementObject.

This is the answer by Nils Pipenbrinck, but implemented in c# fiddle.

https://dotnetfiddle.net/btmjlG

using System;

public class Program
{
    public static void Main()
    {   
        var angle = 180 * Math.PI/180;
        Console.WriteLine(rotate_point(0,0,angle,new Point{X=10, Y=10}).Print());
    }

    static Point rotate_point(double cx, double cy, double angle, Point p)
    {
        double s = Math.Sin(angle);
        double c = Math.Cos(angle);
        // translate point back to origin:
        p.X -= cx;
        p.Y -= cy;
        // rotate point
        double Xnew = p.X * c - p.Y * s;
        double Ynew = p.X * s + p.Y * c;
        // translate point back:
        p.X = Xnew + cx;
        p.Y = Ynew + cy;
        return p;
    }

    class Point

        public string Print(){
            return $"{X},{Y}";

}

Ps: Apparently I can’t comment, so I’m obligated to post it as an answer ...

A void* pointer is used when you want to indicate a pointer to a hunk of memory without specifying the type. C's malloc returns such a pointer, expecting you to cast it to a particular type immediately. It really isn't useful until you cast it to another pointer type. You're expected to know which type to cast it to, the compiler has no reflection capability to know what the underlying type should be.

onchange will work only if the value of the textbox changed compared to the value it had before, so for the first time it won't work because the state didn't change.

So it is better to use onblur event or on submitting the form.

function checkTextField(field) {_x000D_
  document.getElementById("error").innerText =_x000D_
    (field.value === "") ? "Field is empty." : "Field is filled.";_x000D_
}

<input type="text" onblur="checkTextField(this);" />_x000D_
<p id="error"></p>

(Or old live demo.)

If you want to build Java EE applications, it's best to use Eclipse IDE for Java EE. It has editors from HTML to JSP/JSF, Javascript. It's rich for webapps development, and provide plugins and tools to develop Java EE applications easily (all bundled).

Eclipse Classic is basically the full featured Eclipse without the Java EE part.

What went wrong?

When you include jQuery the first time:

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/ui/1.11.0/jquery-ui.js"></script>

The second script plugs itself into jQuery, and "adds" $(...).datepicker.

But then you are including jQuery once again:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>

It undoes the plugging in and therefore $(...).datepicker becomes undefined.

Although the first $(document).ready block appears before that, the anonymous callback function body is not executed until all scripts are loaded, and by then $(...) (window.$ to be precise) is referring to the most recently loaded jQuery.

You would not run into this if you called $('.dateinput').datepicker immediately rather than in $(document).ready callback, but then you'd need to make sure that the target element (with class dateinput) is already in the document before the script, and it's generally advised to use the ready callback.

Solution

If you want to use datepicker from jquery-ui, it would probably make most sense to include the jquery-ui script after bootstrap. jquery-ui 1.11.4 is compatible with jquery 1.6+ so it will work fine.

Alternatively (in particular if you are not using jquery-ui for anything else), you could try bootstrap-datepicker.

You can use forget method on the widget

from tkinter import *

root = Tk()

b = Button(root, text="Delete me", command=b.forget)
b.pack()

b['command'] = b.forget

root.mainloop()

Retrieve year, month, and day, and then put them together. Straight, simple, and accurate.

function formatDate(date) {_x000D_
    var year = date.getFullYear().toString();_x000D_
    var month = (date.getMonth() + 101).toString().substring(1);_x000D_
    var day = (date.getDate() + 100).toString().substring(1);_x000D_
    return year + "-" + month + "-" + day;_x000D_
}_x000D_
_x000D_
//Usage example:_x000D_
alert(formatDate(new Date()));

Java <= 6.x just allows you to catch one exception for each catch block:

try {

} catch (ExceptionType name) {

} catch (ExceptionType name) {

}

Documentation:

Each catch block is an exception handler and handles the type of exception indicated by its argument. The argument type, ExceptionType, declares the type of exception that the handler can handle and must be the name of a class that inherits from the Throwable class.

For Java 7 you can have multiple Exception caught on one catch block:

catch (IOException|SQLException ex) {
    logger.log(ex);
    throw ex;
}

Documentation:

In Java SE 7 and later, a single catch block can handle more than one type of exception. This feature can reduce code duplication and lessen the temptation to catch an overly broad exception.

Reference: http://docs.oracle.com/javase/tutorial/essential/exceptions/catch.html

On Windows 7,64 bit,the above solution (Onur Turhan's) worked for me with slight changes as below

C:\Users\MyName > heroku login

Enter email/password

C:\Users\MyName >ssh-keygen -t rsa -f id_rsa

This generated two files(id_rsa and id_rsa.pub) in my c:\Users\MyName directory (Not in .ssh directory)

heroku keys:add id_rsa.pub
git clone [email protected]:some-heiku-xxxx.git -o heroku

I guess adding the correct "id_rsa.pub" file is the most important.After generating the public key using keygen just verify that you are adding correct key by looking at the time-stamp when it was created.

This won't fail on Linq2Objects, but it will fail for Linq2SQL, so I am assuming that you are talking about the SQL provider or something similar.

The reason has to do with the way that the SQL provider handles your lambda expression. It doesn't take it as a function Func<P,T>, but an expression Expression<Func<P,T>>. It takes that expression tree and translates it so an actual SQL statement, which it sends off to the server.

The translator knows how to handle basic operators, but it doesn't know how to handle methods on objects. It doesn't know that IsNullOrEmpty(x) translates to return x == null || x == string.empty. That has to be done explicitly for the translation to SQL to take place.

To complete Zachary's answer, here is a workaround for the "extend in overrides" limitation of eslint config :

overrides: [
  Object.assign(
    {
      files: [ '**/*.test.js' ],
      env: { jest: true },
      plugins: [ 'jest' ],
    },
    require('eslint-plugin-jest').configs.recommended
  )
]

Try this:

TextView textview = (TextView) findViewById(R.id.textview);

Typeface tf= Typeface.createFromAsset(getAssets(),"fonts/Tahoma.ttf");
textview .setTypeface(tf);

Having just gone round the internet to read up on this and the options in Spring I'd second Luke's answer, use BCrypt (it's mentioned in the source code at Spring).

The best resource I found to explain why to hash/salt and why use BCrypt is a good choice is here: Salted Password Hashing - Doing it Right.

Another advantage of using the '[[' operator is that it works both with data.frame and data.table. So if the function has to be made running for both data.frame and data.table, and you want to extract a column from it as a vector then

data[["column_name"]] 

is best.

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

git push heroku $(git branch --show-current):master

I have solved this if you are using array called for 2 tables. Example you have, $tableA['yellow'] and $tableA['blue'] . You are getting these 2 values and you want to add another element inside them to separate them by their type.

foreach ($tableA['yellow'] as $value) {
    $value->type = 'YELLOW';  //you are adding new element named 'type'
}

foreach ($tableA['blue'] as $value) {
    $value->type = 'BLUE';  //you are adding new element named 'type'
}

So, both of the tables value will have new element called type.
