I use a trigger as a workaround to set a datetime field to NOW() for new inserts:

CREATE TRIGGER `triggername` BEFORE INSERT ON  `tablename` 
FOR EACH ROW 
SET NEW.datetimefield = NOW()

it should work for updates too

Answers by Johan & Leonardo involve converting to a timestamp field. Although this is probably ok for the use case presented in the question (storing RegisterDate and LastVisitDate), it is not a universal solution. See datetime vs timestamp question.

...an old one... anyway I had the same issue with MariaDB

In my case most pathes contain special characters like: # Wrapping pathes in my.ini in double quotes made the trick - e.g.

datadir="C:/#windata64/db/MariaDB/data"

You could also add the external jar file to the project. Go to your project-->properties-->java build path-->libraries, add external JARS. Then add your downloaded jar file.

This way should work, change "char" to "Character":

public static void main(String[] args){
  Character[] list = {'m', 'e', 'y'};
  System.out.println(Arrays.asList(list).indexOf('e')); // print "1"
}

Try following from Removing duplicates from an Array(simple):

Array.prototype.removeDuplicates = function (){
  var temp=new Array();
  this.sort();
  for(i=0;i<this.length;i++){
    if(this[i]==this[i+1]) {continue}
    temp[temp.length]=this[i];
  }
  return temp;
} 

Edit:

This code doesn't need sort:

Array.prototype.removeDuplicates = function (){
  var temp=new Array();
  label:for(i=0;i<this.length;i++){
        for(var j=0; j<temp.length;j++ ){//check duplicates
            if(temp[j]==this[i])//skip if already present 
               continue label;      
        }
        temp[temp.length] = this[i];
  }
  return temp;
 } 

(But not a tested code!)

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

In addition to tcash21's numeric indexing if OP may have been looking for negative indexing by name. Here's a few ways I know, some are risky than others to use:

mtcars[, -which(names(mtcars) == "carb")]  #only works on a single column
mtcars[, names(mtcars) != "carb"]          #only works on a single column
mtcars[, !names(mtcars) %in% c("carb", "mpg")] 
mtcars[, -match(c("carb", "mpg"), names(mtcars))] 
mtcars2 <- mtcars; mtcars2$hp <- NULL         #lost column (risky)


library(gdata) 
remove.vars(mtcars2, names=c("mpg", "carb"), info=TRUE) 

Generally I use:

mtcars[, !names(mtcars) %in% c("carb", "mpg")] 

because I feel it's safe and efficient.

In my case the error was due to missing /data/db folder which the mongodb uses to store your data. Please type this command $sudo mongod in your terminal. If the error message is something like :

missing data/db folder error

Simply create the folder and you are good to go.

I suggest you take a look at tiny httpd. If you want to write it from scratch, then you'll want to thoroughly read RFC 2616. Use BSD sockets to access the network at a really low level.

Add the following lines to the [alias] section of your .gitconfig file

ignore = update-index --assume-unchanged
unignore = update-index --no-assume-unchanged
ignored = !git ls-files -v | grep "^[[:lower:]]"

Now you can use git ignore my_file to ignore changes to the local file, and git unignore my_file to stop ignoring the changes. git ignored lists the ignored files.

This answer was gleaned from http://gitready.com/intermediate/2009/02/18/temporarily-ignoring-files.html.

As I discussed here ,

if you want to pass custom JSON object to MVC action then you can use this solution, it works like a charm.

public string GetData() {
  // InputStream contains the JSON object you've sent
  String jsonString = new StreamReader(this.Request.InputStream).ReadToEnd();

  // Deserialize it to a dictionary
  var dic =
    Newtonsoft.Json.JsonConvert.DeserializeObject < Dictionary < String,
    dynamic >> (jsonString);

  string result = "";

  result += dic["firstname"] + dic["lastname"];

  // You can even cast your object to their original type because of 'dynamic' keyword
  result += ", Age: " + (int) dic["age"];

  if ((bool) dic["married"])
    result += ", Married";

  return result;
}

The real benefit of this solution is that you don't require to define a new class for each combination of arguments and beside that, you can cast your objects to their original types easily.

You can use a helper method like this to facilitate your job:

public static Dictionary < string, dynamic > GetDic(HttpRequestBase request) {
  String jsonString = new StreamReader(request.InputStream).ReadToEnd();
  return Newtonsoft.Json.JsonConvert.DeserializeObject < Dictionary < string, dynamic >> (jsonString);
}

Your sort logic is wrong. This is the pseudo-code for bubble sort:

for i = 1:n,
    swapped = false
    for j = n:i+1, 
        if a[j] < a[j-1], 
            swap a[j,j-1]
            swapped = true
    ? invariant: a[1..i] in final position
    break if not swapped
end

See this sorting web site for good tutorial on all the various sorting methods.

Are you sure you've connected to the db? (I ask because I don't see a port specified)

try:

mongoose.connection.on("open", function(){
  console.log("mongodb is connected!!");
});

Also, you can do a "show collections" in mongo shell to see the collections within your db - maybe try adding a record via mongoose and see where it ends up?

From the look of your connection string, you should see the record in the "test" db.

Hope it helps!

If you dont find any fonts that you like from Google.com/webfonts or fontsquirrel.com you can always make your own web font with a font you made.

Just type import pdb in jupyter notebook, and then use this cheatsheet to debug. It's very convenient.

c --> continue, s --> step, b 12 --> set break point at line 12 and so on.

Some useful links: Python Official Document on pdb, Python pdb debugger examples for better understanding how to use the debugger commands.

Some useful screenshots:

There is no built-in functionality in VBS for that, however, you can use the FileSystemObject FileExists function for that :

Option Explicit
DIM fso    
Set fso = CreateObject("Scripting.FileSystemObject")

If (fso.FileExists("C:\Program Files\conf")) Then
  WScript.Echo("File exists!")
  WScript.Quit()
Else
  WScript.Echo("File does not exist!")
End If

WScript.Quit()

By implementing ImplicitNamingStrategy you may create rules for automatically naming the constraints. Note you add your naming strategy to the metadataBuilder during Hibernate's initialization:

metadataBuilder.applyImplicitNamingStrategy(new MyImplicitNamingStrategy());

It works for @UniqueConstraint, but not for @Column(unique = true), which always generates a random name (e.g. UK_3u5h7y36qqa13y3mauc5xxayq).

There is a bug report to solve this issue, so if you can, please vote there to have this implemented. Here: https://hibernate.atlassian.net/browse/HHH-11586

Thanks.

The proper way to do this is to use multiple tables and JOIN them in your queries.

For example:

CREATE TABLE person (
`id` INT NOT NULL PRIMARY KEY,
`name` VARCHAR(50)
);

CREATE TABLE fruits (
`fruit_name` VARCHAR(20) NOT NULL PRIMARY KEY,
`color` VARCHAR(20),
`price` INT
);

CREATE TABLE person_fruit (
`person_id` INT NOT NULL,
`fruit_name` VARCHAR(20) NOT NULL,
PRIMARY KEY(`person_id`, `fruit_name`)
);

The person_fruit table contains one row for each fruit a person is associated with and effectively links the person and fruits tables together, I.E.

1 | "banana"
1 | "apple"
1 | "orange"
2 | "straberry"
2 | "banana"
2 | "apple"

When you want to retrieve a person and all of their fruit you can do something like this:

SELECT p.*, f.*
FROM person p
INNER JOIN person_fruit pf
ON pf.person_id = p.id
INNER JOIN fruits f
ON f.fruit_name = pf.fruit_name

The issue with

List<String> list = new LinkedList();

is that on the left hand side, you are using the generic type List<String> where on the right side you are using the raw type LinkedList. Raw types in Java effectively only exist for compatibility with pre-generics code and should never be used in new code unless you absolutely have to.

Now, if Java had generics from the beginning and didn't have types, such as LinkedList, that were originally created before it had generics, it probably could have made it so that the constructor for a generic type automatically infers its type parameters from the left-hand side of the assignment if possible. But it didn't, and it must treat raw types and generic types differently for backwards compatibility. That leaves them needing to make a slightly different, but equally convenient, way of declaring a new instance of a generic object without having to repeat its type parameters... the diamond operator.

As far as your original example of List<String> list = new LinkedList(), the compiler generates a warning for that assignment because it must. Consider this:

List<String> strings = ... // some list that contains some strings

// Totally legal since you used the raw type and lost all type checking!
List<Integer> integers = new LinkedList(strings);

Generics exist to provide compile-time protection against doing the wrong thing. In the above example, using the raw type means you don't get this protection and will get an error at runtime. This is why you should not use raw types.

// Not legal since the right side is actually generic!
List<Integer> integers = new LinkedList<>(strings);

The diamond operator, however, allows the right hand side of the assignment to be defined as a true generic instance with the same type parameters as the left side... without having to type those parameters again. It allows you to keep the safety of generics with almost the same effort as using the raw type.

I think the key thing to understand is that raw types (with no <>) cannot be treated the same as generic types. When you declare a raw type, you get none of the benefits and type checking of generics. You also have to keep in mind that generics are a general purpose part of the Java language... they don't just apply to the no-arg constructors of Collections!

There exist many open source projects that handle all the drawing of line charts for you with a couple of lines of code. Here's how you can draw a line chart from data in a couple text (CSV) file with the XChart library. Disclaimer: I'm the lead developer of the project.

In this example, two text files exist in ./CSV/CSVChartRows/. Notice that each row in the files represents a data point to be plotted and that each file represents a different series. series1 contains x, y, and error bar data, whereas series2 contains just x and y, data.

series1.csv

1,12,1.4
2,34,1.12
3,56,1.21
4,47,1.5

series2.csv

1,56
2,34
3,12
4,26

Source Code

public class CSVChartRows {

  public static void main(String[] args) throws Exception {

    // import chart from a folder containing CSV files
    XYChart chart = CSVImporter.getChartFromCSVDir("./CSV/CSVChartRows/", DataOrientation.Rows, 600, 400);

    // Show it
    new SwingWrapper(chart).displayChart();
  }
}

My fellows,

In January 2019 I used a code made before:

 <script type="text/javascript">   
    function imprimir() {
        var divToPrint=document.getElementById("ConsutaBPM");
        newWin= window.open("");
        newWin.document.write(divToPrint.outerHTML);
        newWin.print();
        newWin.close();
    }
</script>

To undestand: ConsutaBPM is a DIV which contains inside phrases and tables. I wanted to print ALL, titles, table, and others. The problem was when TRIED to print the TABLE...

The table mas be defined with BORDER and CELLPADDING:

<table border='1' cellpadding='1' id='Tablbpm1' >

It worked fine!!!

My open source application BugTracker.NET includes a POP3 client that can parse MIME. Both the POP3 code and the MIME code are from other authors, but you can see how it all fits together in my app.

For the MIME parsing, I use http://anmar.eu.org/projects/sharpmimetools/.

See the file POP3Main.cs, POP3Client.cs, and insert_bug.aspx

A simple string replace will do the job. Take a look at the example program below:

using System;

namespace NewLineThingy
{
    class Program
    {
        static void Main(string[] args)
        {
            string str = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";
            str = str.Replace("@", "@" + Environment.NewLine);
            Console.WriteLine(str);
            Console.ReadKey();
        }
    }
}

Use COALESCE to avoid that outcome.

SELECT COALESCE(SUM(column),0)
FROM   table
WHERE  ...

Late to the party. I'm on Windows 10 with JDK 1.8 and Eclipse MARS 1.
I find that

getClass().getClassLoader().getResourceAsStream("path/to/resource");

works and

getClass().getClassLoader().getResourceAsStream("path"+File.separator+"to"+File.separator+"resource");

does not work and

getClass().getClassLoader().getResourceAsStream("path\to\resource");

does not work. The last two are equivalent. So... I have good reason to NOT use File.separator.

The syntax to statically initialize an array uses curly braces, like this:

int array[10] = { 0 };

This will zero-initialize the array.

For multi-dimensional arrays, you need nested curly braces, like this:

int cipher[Array_size][Array_size]= { { 0 } };

Note that Array_size must be a compile-time constant for this to work. If Array_size is not known at compile-time, you must use dynamic initialization. (Preferably, an std::vector).

Either store it in the gridview datakeys collection, or store it in a hidden field inside the same cell, or join the values together. That is the only way. You can't store two values in one link.

It is ||, for example:

select 'Mr ' || ename from emp;

The only "interesting" feature I can think of is that 'x' || null returns 'x', not null as you might perhaps expect.

Internet Explorer 7 (and earlier) displays the value of the alt attribute as a tooltip, when mousing over the image. This is NOT the correct behavior, according to the HTML specification. The title attribute should be used instead. Source: http://www.w3schools.com/tags/att_img_alt.asp

In order to detect mouseleave without taking in account the scroll bar and the autcomplete field or inspect :

document.addEventListener("mouseleave", function(event){

  if(event.clientY <= 0 || event.clientX <= 0 || (event.clientX >= window.innerWidth || event.clientY >= window.innerHeight))
  {

     console.log("I'm out");

  }
});

Conditions explanations:

event.clientY <= 0  is when the mouse leave from the top
event.clientX <= 0  is when the mouse leave from the left
event.clientX >= window.innerWidth is when the mouse leave from the right
event.clientY >= window.innerHeight is when the mouse leave from the bottom

======================== EDIT ===============================

document.addEventListener("mouseleave") seems to be not fired on new firefox version, mouseleave need to be attached to an element like body, or a child element.

I suggest to use instead

document.body.addEventListener("mouseleave")

Or

window.addEventListener("mouseout")

1. find($id) takes an id and returns a single model. If no matching model exist, it returns null.

2. findOrFail($id) takes an id and returns a single model. If no matching model exist, it throws an error¹.

3. first() returns the first record found in the database. If no matching model exist, it returns null.

4. firstOrFail() returns the first record found in the database. If no matching model exist, it throws an error¹.

5. get() returns a collection of models matching the query.

6. pluck($column) returns a collection of just the values in the given column. In previous versions of Laravel this method was called lists.

7. toArray() converts the model/collection into a simple PHP array.

Note: a collection is a beefed up array. It functions similarly to an array, but has a lot of added functionality, as you can see in the docs.

Unfortunately, PHP doesn't let you use a collection object everywhere you can use an array. For example, using a collection in a foreach loop is ok, put passing it to array_map is not. Similarly, if you type-hint an argument as array, PHP won't let you pass it a collection. Starting in PHP 7.1, there is the iterable typehint, which can be used to accept both arrays and collections.

If you ever want to get a plain array from a collection, call its all() method.

¹ The error thrown by the findOrFail and firstOrFail methods is a ModelNotFoundException. If you don't catch this exception yourself, Laravel will respond with a 404, which is what you want most of the time.

ShortcutBadger is a library that adds an abstraction layer over the device brand and current launcher and offers a great result. Works with LG, Sony, Samsung, HTC and other custom Launchers.

It even has a way to display Badge Count in Pure Android devices desktop.

Updating the Badge Count in the application icon is as easy as calling:

int badgeCount = 1;
ShortcutBadger.applyCount(context, badgeCount);

It includes a demo application that allows you to test its behavior.

You need to include the appropriate header

#include <stdio.h>

If you're not sure which header a standard function is defined in, the function's man page will state this.

x86 means Intel 80x86 compatible. This used to include the 8086, a 16-bit only processor. Nowadays it roughly means any CPU with a 32-bit Intel compatible instruction set (usually anything from Pentium onwards). Never read x32 being used.

x64 means a CPU that is x86 compatible but has a 64-bit mode as well (most often the 64-bit instruction set as introduced by AMD is meant; Intel's idea of a 64-bit mode was totally stupid and luckily Intel admitted that and is now using AMDs variant).

So most of the time you can simplify it this way: x86 is Intel compatible in 32-bit mode, x64 is Intel compatible in 64-bit mode.

Huffman coding generally works okay for this.

Different solution, webkit based. As mentioned already, anytime Chrome finds a password field it autocompletes the email. AFAIK, this is regardless of autocomplete = [whatever].

To circumvent this change the input type to text and apply the webkit security font in whatever form you want.

.secure-font{
-webkit-text-security:disc;}

<input type ="text" class="secure-font">

From what I can see this is at least as secure as input type=password, it's copy and paste secure. However it is vulnerable by removing the style which will remove asterisks, of course input type = password can easily be changed to input type = text in the console to reveal any autofilled passwords so it's much the same really.

By default Vagrant uses a generated private key to login, you can try this:

My experience with windows client and linux/mysql server:

When sqldev is used in a windows client and mysql is installed in a linux server meaning, sqldev network access to mysql.

Assuming mysql is already up and running and the databases to be accessed are up and functional:

• Ensure the version of sqldev (32 or 64). If 64 and to avoid dealing with path access copy a valid 64 version of msvcr100.dll into directory ~\sqldeveloper\jdev\bin.

a. Open the file msvcr100.dll in notepad and search for first occurrence of “PE “

 i. “PE  d” it is 64.

ii. “PE  L” it is 32.

b. Note: if sqldev is 64 and msvcr100.dll is 32, the application gets stuck at startup.

• For sqldev to work with mysql there is need of the JDBC jar driver. Download it from mysql site.

a. Driver name = mysql-connector-java-x.x.xx

b. Copy it into someplace related to your sqldeveloper directory.

c. Set it up in menu sqldev Tools/Preferences/Database/Third Party JDBC Driver (add entry)

• In Linux/mysql server change file /etc/mysql/mysql.conf.d/mysqld.cnf look for

bind-address = 127.0.0.1 (this linux localhost)

and change to

bind-address = xxx.xxx.xxx.xxx (this linux server real IP or machine name if DNS is up)

• Enter to linux mysql and grant needed access for example

# mysql –u root -p

GRANT ALL ON . to root@'yourWindowsClientComputerName' IDENTIFIED BY 'mysqlPasswd';

flush privileges;

restart mysql - sudo /etc/init.d/mysql restart

• Start sqldev and create a new connection

a. user = root

b. pass = (your mysql pass)

c. Choose MySql tab

 i.   Hostname = the linux IP hostname

 ii.  Port     = 3306 (default for mysql)

 iii. Choose Database = (from pull down the mysql database you want to use)

 iv.  save and connect

That is all I had to do in my case.

Thank you,

Use the .str()-method:

Manages the contents of the underlying string object.

1) Returns a copy of the underlying string as if by calling rdbuf()->str().

2) Replaces the contents of the underlying string as if by calling rdbuf()->str(new_str)...

Notes

The copy of the underlying string returned by str is a temporary object that will be destructed at the end of the expression, so directly calling c_str() on the result of str() (for example in auto *ptr = out.str().c_str();) results in a dangling pointer...

I had the exact same problem and it was driving me crazy (Windows 10 and VS Code 1.49.1)

Other answers talk about installing Selenium, but it's clear to me that you've already did that, but you still get the ImportError: No module named 'selenium'.

So, what's going on?

Two things:

1. You installed Selenium in this folder /Library/Python/2.7/site-packages and selenium-2.46.0-py2.7.egg
2. But you're probably running a version of Python, in which you didn't install Selenium. For instance: /Library/Python/3.8/site-packages... you won't find Selenium installed here and that's why the module isn't found.

The solution? You have to install selenium in the same directory to the Python version you're using or change the interpreter to match the directory where Selenium is installed.

In VS Code you change the interpreter here (at the bottom left corner of the screen)

Ready! Now your Python interpreter should find the module.

You can loop through all the Animals using foreach and put it into NewAnimals.

When using latest WHM (v66.0.23) you may go to MultiPHP INI Editor choose PHP version and set session.save_path to default i.e. /var/cpanel/php/sessions/ea-php70 instead of previous simple tmp - this helped me to get rid of such errors.

This can happen for more than one reason. In my case this happened due to a permissions issue. The user that the task was running as didn't have permission to write to the logs directory so it failed with this error.

$(`input[id="${this.name}"]`).hide();

As you're using an ID, this would perform better

$(`#${this.name}`).hide();

I highly recommend being more specific with your approach to hiding elements via button clicks. I would opt for using data-attributes instead. For example

<input id="bx" type="text">
<button type="button" data-target="#bx" data-method="hide">Hide some input</button>

Then, in your JavaScript

// using event delegation so no need to wrap it in .ready()
$(document).on('click', 'button[data-target]', function() {
    var $this = $(this),
        target = $($this.data('target')),
        method = $this.data('method') || 'hide';
    target[method]();
});

Now you can completely control which element you're targeting and what happens to it via the HTML. For example, you could use data-target=".some-class" and data-method="fadeOut" to fade-out a collection of elements.

Try this code.

public void send (String fileName) {
    String SFTPHOST = "host:IP";
    int SFTPPORT = 22;
    String SFTPUSER = "username";

final long usedMemInMB=(runtime.totalMemory() - runtime.freeMemory()) / 1048576L;
final long maxHeapSizeInMB=runtime.maxMemory() / 1048576L;
final long availHeapSizeInMB = maxHeapSizeInMB - usedMemInMB;

It is a strange code. It return MaxMemory - (totalMemory - freeMemory). If freeMemory equals 0, then the code will return MaxMemory - totalMemory, so it can more or equals 0. Why freeMemory not used?

Since you are in a controller, the action method is given a Request parameter.

You can access all POST data with $request->request->all();. This returns a key-value pair array.

When using GET requests you access data using $request->query->all();

When you use float without width, there remains some space in that row. To block this space you can use clear:both; in next element.

I just solve this error while using capybara in ror project by adding:

Capybara.ignore_elements = true

to features/support/env.rb.

These answers are no longer recommended since try_files works faster than if in this context. Simply add try_files in your php location block to test if the file exists, otherwise return a 404.

location ~ \.php {
    try_files $uri =404;
    ...
}

Either you iterate through the options, or put the same text inside another attribute of the option and select with that.

The trick is to create subclasses of ViewHolder and then cast them.

public class GroupViewHolder extends RecyclerView.ViewHolder {
    TextView mTitle;
    TextView mContent;
    public GroupViewHolder(View itemView) {
        super (itemView);
        // init views...
    }
}

public class ImageViewHolder extends RecyclerView.ViewHolder {
    ImageView mImage;
    public ImageViewHolder(View itemView) {
        super (itemView);
        // init views...
    }
}

private static final int TYPE_IMAGE = 1;
private static final int TYPE_GROUP = 2;  

And then, at runtime do something like this:

@Override
public int getItemViewType(int position) {
    // here your custom logic to choose the view type
    return position == 0 ? TYPE_IMAGE : TYPE_GROUP;
}

@Override
public void onBindViewHolder (ViewHolder viewHolder, int i) {

    switch (viewHolder.getItemViewType()) {

        case TYPE_IMAGE:
            ImageViewHolder imageViewHolder = (ImageViewHolder) viewHolder;
            imageViewHolder.mImage.setImageResource(...);
            break;

        case TYPE_GROUP:
            GroupViewHolder groupViewHolder = (GroupViewHolder) viewHolder;
            groupViewHolder.mContent.setText(...)
            groupViewHolder.mTitle.setText(...);
            break;
    }
}

Hope it helps.

With python >= 3.5 you can use mock_object.assert_not_called().

That seems to be an extra image being shown there.

You can try using this

<img src="/images/image_of_video.png" alt="image" />
/* write your code for the video here */

Now using jQuery play the video and hide the image as

$('img').click(function () {
  $(this).hide();
  // use the parameters to play the video now..
})

For Cordova OR Ionic Hybrid App

I have the very similar problem with my Ionic 1 Cordova Build after Integrating the Firebase Cloud Messaging ( FCM )

I fixed this issue by the following steps

So one fix will be: inside platforms/android open project.properties (Its a file ) , you will have something like this

cordova.system.library.1=com.google.android.gms:play-services-ads:+
cordova.system.library.2=com.google.firebase:firebase-core:+
cordova.system.library.3=com.google.firebase:firebase-messaging:+

Replace the

+

Sign with your target version number - like the following

cordova.system.library.1=com.google.android.gms:play-services-ads:9.0.0
cordova.system.library.2=com.google.firebase:firebase-core:9.0.0
cordova.system.library.3=com.google.firebase:firebase-messaging:9.0.0

Save the file

Then take build using

 ionic cordova run android

I hope this will work for everyone

I would use the translate method without translation table. It deletes the letters in second argument in recent Python versions.

def remove_chars(line):
    line7=line[7].translate(None,'abcd')
    return line[:7]+[line7]+line[8:]

line= ['ad','da','sdf','asd',
        '3424','342sfas','asdfaf','sdfa',
        'afase']
print line[7]
line = remove_chars(line)
print line[7]

afaik no iPhone uses a pixel-ratio of 1.5

Support for stored procedures in EF Core 1.0 is resolved now, this also supports the mapping of multiple result-sets.

And you can call it like this in c#

var userType = dbContext.Set().FromSql("dbo.SomeSproc @Id = {0}, @Name = {1}", 45, "Ada");

If I'm not using any category then how can I use this code? Actually, I want to use this code for custom post type.

This is quite a misleading status. It should be called "reading and filtering data".

This means that MySQL has some data stored on the disk (or in memory) which is yet to be read and sent over. It may be the table itself, an index, a temporary table, a sorted output etc.

If you have a 1M records table (without an index) of which you need only one record, MySQL will still output the status as "sending data" while scanning the table, despite the fact it has not sent anything yet.

Below piece of code returns ONLY the 'subfolders' in a 'folder' from s3 bucket.

import boto3
bucket = 'my-bucket'
#Make sure you provide / in the end
prefix = 'prefix-name-with-slash/'  

client = boto3.client('s3')
result = client.list_objects(Bucket=bucket, Prefix=prefix, Delimiter='/')
for o in result.get('CommonPrefixes'):
    print 'sub folder : ', o.get('Prefix')

For more details, you can refer to https://github.com/boto/boto3/issues/134

You are doing integer arithmetic, so there the result is correct. Try

percentage=((double)number/total)*100;

BTW the %f expects a double not a float. By pure luck that is converted here, so it works out well. But generally you'd mostly use double as floating point type in C nowadays.

As a general way to handle error in a loop like your sample code, I would rather use:

on error resume next
for each...
    'do something that might raise an error, then
    if err.number <> 0 then
         ...
    end if
 next ....

I don't know of anyway to step through the execution of a .bat file but you can use echo and pause to help with debugging.

ECHO
Will echo a message in the batch file. Such as ECHO Hello World will print Hello World on the screen when executed. However, without @ECHO OFF at the beginning of the batch file you'll also get "ECHO Hello World" and "Hello World." Finally, if you'd just like to create a blank line, type ECHO. adding the period at the end creates an empty line.

PAUSE
Prompt the user to press any key to continue.

This is a quick fix and can be even more optimized but it will work fine. This code will replace all non empty tags with "" and strips all html tags form a given input text .You can run it using ./file.py input output

    #!/usr/bin/python
import sys

def replace(strng,replaceText):
    rpl = 0
    while rpl > -1:
        rpl = strng.find(replaceText)
        if rpl != -1:
            strng = strng[0:rpl] + strng[rpl + len(replaceText):]
    return strng


lessThanPos = -1
count = 0
listOf = []

try:
    #write File
    writeto = open(sys.argv[2],'w')

    #read file and store it in list
    f = open(sys.argv[1],'r')
    for readLine in f.readlines():
        listOf.append(readLine)         
    f.close()

    #remove all tags  
    for line in listOf:
        count = 0;  
        lessThanPos = -1  
        lineTemp =  line

            for char in lineTemp:

            if char == "<":
                lessThanPos = count
            if char == ">":
                if lessThanPos > -1:
                    if line[lessThanPos:count + 1] != '<>':
                        lineTemp = replace(lineTemp,line[lessThanPos:count + 1])
                        lessThanPos = -1
            count = count + 1
        lineTemp = lineTemp.replace("&lt","<")
        lineTemp = lineTemp.replace("&gt",">")                  
        writeto.write(lineTemp)  
    writeto.close()

I would recommend everyone look into CSS grids. It has been supported by most browsers now since about 2017. Here is a link to some documentation: https://css-tricks.com/snippets/css/complete-guide-grid/ . It is so much easier to keep your page elements where you want them, especially when it comes to responsiveness. It took me all of 20 minutes to learn how to do it, and I'm a newbie!

<div class="grid-div">
    <p class="hello">Hello</p>
    <p class="world">World</p>
</div>


//begin css//

.grid-div {
    display: grid;
    grid-template-columns: 50% 50%;
    grid-template-rows: 50% 50%;
}

.hello {
    grid-column-start: 2;
    grid-row-start: 2;
}

.world {
    grid-column-start: 1;
    grid-row-start: 2;
}

This code will split the page into 4 equal quadrants, placing the "Hello" in the bottom right, and the "World" in the bottom left without having to change their positioning or playing with margins.

This can be extrapolated into very complex grid layouts with overlapping, infinite grids of all sizes, and even grids nested inside grids, without losing control of your elements every time something changes (MS Word I'm looking at you).

Hope this helps whoever still needs it!

One can use regular expressions, too:

var thingToTest = "B";_x000D_
if (/A|B/.test(thingToTest)) alert("Do something!")

Here's an example of regular expressions in general:

var myString = "This is my search subject"_x000D_
if (/my/.test(myString)) alert("Do something here!")

This will look for "my" within the variable "myString". You can substitute a string directly in place of the "myString" variable.

As an added bonus you can add the case insensitive "i" and the global "g" to the search as well.

var myString = "This is my search subject"_x000D_
if (/my/ig.test(myString)) alert("Do something here");

This should do the trick! :)

From Bootstrap 4

.carousel-item{
    height: 200px;
} 
.carousel-item img{
    height: 200px;
}

it has been a while but my answer may help someone:

if you already defined the relation properly you can use this:

        var res = query.Products.Select(m => new
        {
            productID = product.Id,
            categoryID = m.ProductCategory.Select(s => s.Category.ID).ToList(),
        }).ToList();

Even though the above solutions do work,This answer is for you in case you want to reverse the clock instead of undoing a git pull.I mean if you want to get your exact repo the way it was X Mins back then run the command

git reset --hard branchName@{"X Minutes ago"}

Note: before you actually go ahead and run this command please only try this command if you are sure about the time you want to go back to and heres about my situation.

I was currently on a branch develop, I was supposed to checkout to a new branch and pull in another branch lets say Branch A but I accidentally ran git pull origin B before checking out.

so to undo this change I tried this command

git reset --hard develop@{"10 Minutes ago"}

if you are on windows cmd and get error: unknown switch `e

try adding quotes like this

git reset --hard 'develop@{"10 Minutes ago"}'

You could use threading or multiprocessing.

Due to peculiarities of CPython, threading is unlikely to achieve true parallelism. For this reason, multiprocessing is generally a better bet.

Here is a complete example:

from multiprocessing import Process

def func1():
  print 'func1: starting'
  for i in xrange(10000000): pass
  print 'func1: finishing'

def func2():
  print 'func2: starting'
  for i in xrange(10000000): pass
  print 'func2: finishing'

if __name__ == '__main__':
  p1 = Process(target=func1)
  p1.start()
  p2 = Process(target=func2)
  p2.start()
  p1.join()
  p2.join()

The mechanics of starting/joining child processes can easily be encapsulated into a function along the lines of your runBothFunc:

def runInParallel(*fns):
  proc = []
  for fn in fns:
    p = Process(target=fn)
    p.start()
    proc.append(p)
  for p in proc:
    p.join()

runInParallel(func1, func2)

The data type in the Job table (Varchar2(20)) does not match the data type in the USER table (NUMBER NOT NULL).

Well firstly C doesn't have public/private/virtual functions. That's C++ and it has different conventions. In C typically you have:

• Constants in ALL_CAPS
• Underscores to delimit words in structs or function names, hardly ever do you see camel case in C;
• structs, typedefs, unions, members (of unions and structs) and enum values typically are in lower case (in my experience) rather than the C++/Java/C#/etc convention of making the first letter a capital but I guess it's possible in C too.

C++ is more complex. I've seen a real mix here. Camel case for class names or lowercase+underscores (camel case is more common in my experience). Structs are used rarely (and typically because a library requires them, otherwise you'd use classes).

This fixes the math to scale to the max size in both width and height rather than just one depending on the width and height of the original.

- (UIImage *) scaleProportionalToSize: (CGSize)size
{
    float widthRatio = size.width/self.size.width;
    float heightRatio = size.height/self.size.height;

    if(widthRatio > heightRatio)
    {
        size=CGSizeMake(self.size.width*heightRatio,self.size.height*heightRatio);
    } else {
        size=CGSizeMake(self.size.width*widthRatio,self.size.height*widthRatio);
    }

    return [self scaleToSize:size];
}

In my case the problem was because of conflicting Jars.

Scenario: Windows 8.1, VS2013 Ultimate, SQL Express Installed and running, SQL Server Browser Disabled. This worked for me:

1. First I enabled SQL Server Browser under services.
2. In Visual Studio: Open the Package Manager Console then type: Enable-Migrations; Then Type Enable-Migrations -ContextTypeName YourContextDbName that created the Migrations folder in VS.
3. Inside the Migrations folder you will find the "Configuration.cs" file, turn on automatic migrations by: AutomaticMigrationsEnabled = true;
4. Run your application again, the environment creates a DefaultConnection and you will see the new tables from your context. This new connection points to the localdb. The created connection string shows: Data Source=(LocalDb)\v11.0 ... (more parameters and path to the created mdf file)

You can now create a new connection with Server name: (LocalDb)\v11.0 (hit refresh) Connect to a database: Select your new database under the dropdown.

I hope it helps.

Try this.

If you are printing to stderr using the stdio library, a call to fflush(stderr) should flush the buffer and get you real-time logging.

You can also use Object.keys() and iterate over the object keys like below to get the value:

var p = {_x000D_
    "p1": "value1",_x000D_
    "p2": "value2",_x000D_
    "p3": "value3"_x000D_
};_x000D_
_x000D_
Object.keys(p).forEach((key)=> {_x000D_
 console.log(key +' -> '+ p[key]);_x000D_
});

Generating a random string of characters is easy - just use java.util.Random and a string containing all the characters you want to be available, e.g.

public static String generateString(Random rng, String characters, int length)
{
    char[] text = new char[length];
    for (int i = 0; i < length; i++)
    {
        text[i] = characters.charAt(rng.nextInt(characters.length()));
    }
    return new String(text);
}

Now, for uniqueness you'll need to store the generated strings somewhere. How you do that will really depend on the rest of your application.

var data={
 userName: $('#userName').val(),
 email: $('#email').val(),
 //add other properties similarly
}

and

$.ajax({
        type: "POST",
        url: "http://rt.ja.com/includes/register.php?submit=1",
        data: data

        success: function(html)
        {   
            //alert(html);
            $('#userError').html(html);
            $("#userError").html(userChar);
            $("#userError").html(userTaken);
        }
    });

You dont have to bother about anything else. jquery will handle the serialization etc. also you can append the submit query string parameter submit=1 into the data json object.

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

Check out this Article, it shows how to mimic SQL ROW_NUMBER() with a partition by in MySQL. I ran into this very same scenario in a WordPress Implementation. I needed ROW_NUMBER() and it wasn't there.

http://www.explodybits.com/2011/11/mysql-row-number/

The example in the article is using a single partition by field. To partition by additional fields you could do something like this:

  SELECT  @row_num := IF(@prev_value=concat_ws('',t.col1,t.col2),@row_num+1,1) AS RowNumber
         ,t.col1 
         ,t.col2
         ,t.Col3
         ,t.col4
         ,@prev_value := concat_ws('',t.col1,t.col2)
    FROM table1 t,
         (SELECT @row_num := 1) x,
         (SELECT @prev_value := '') y
   ORDER BY t.col1,t.col2,t.col3,t.col4 

Using concat_ws handles null's. I tested this against 3 fields using an int, date, and varchar. Hope this helps. Check out the article as it breaks this query down and explains it.

Working Example: JSFiddle

Cut and paste solution that works for all major browsers (Even Safari)

Any height or width will work

<style>
  .list_container {
    direction: rtl;
    overflow:auto;
    height: 50px;
    width: 50px;
  }

  .item_direction {
    direction:ltr;
  }
</style>
<div class="list_container">
  <div class="item_direction">1</div>
  <div class="item_direction">2</div>
  <div class="item_direction">3</div>
  <div class="item_direction">4</div>
  <div class="item_direction">5</div>
  <div class="item_direction">6</div>
  <div class="item_direction">7</div>
  <div class="item_direction">8</div>
  <div class="item_direction">9</div>
  <div class="item_direction">10</div>
  <div class="item_direction">11</div>
  <div class="item_direction">12</div>
</div>

Optionally add class="item_direction to each item to change the direction of the text flow back, while preserving the container direction.

Running .NET core (3.1.4) on IIS behind a Load balancer did not work with other suggested solutions.

Manually reading the X-Forwarded-For header does.

IPAddress ip;
var headers = Request.Headers.ToList();
if (headers.Exists((kvp) => kvp.Key == "X-Forwarded-For"))
{
    // when running behind a load balancer you can expect this header
    var header = headers.First((kvp) => kvp.Key == "X-Forwarded-For").Value.ToString();
    ip = IPAddress.Parse(header);
}
else
{
    // this will always have a value (running locally in development won't have the header)
    ip = Request.HttpContext.Connection.RemoteIpAddress;
}

You can iterate through the array and set a "flag" value if strpos returns false.

$flag = false;
foreach ($find_letters as $letter)
{
    if (strpos($string, $letter) === false)
    {
        $flag = true;
    }
}

Then check the value of $flag.

This error shows up when you are treating an array or string as a Hash. In this line myHash.each do |item| you are assigning item to a two-element array [key, value], so item[:symbol] throws an error.

How about this?

Get-ADGroupMember 'Group name' | measure-object | select count

Try this

Objective C

  [TableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];

  [TableView setSeparatorColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"[email protected]"]]];

Swift

    tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine
    tableView.separatorColor = UIColor(patternImage: UIImage(named: "YOUR_IMAGE_NAME")!)

If you make all the properties animated the same, you can set each separately which will allow you to not repeat the code.

 transition: all 2s;
 transition-property: color, text-shadow;

There is more about it here: CSS transition shorthand with multiple properties?

I would avoid using the property all (transition-property overwrites 'all'), since you could end up with unwanted behavior and unexpected performance hits.

Could try to restart computer if it doesn't work after you are quite sure that PATH is set correctly.

In my case on windows 7, I always got the error on WebDriverException: Message: for chromedriver, gecodriver, IEDriverServer. I am pretty sure that i have correct path. Restart computer, all work

I just ran into this problem and stumbled across a different situation. Although it's probably just a unicorn, I thought I'd lay it out.

I had one session that was smaller, and I noticed that the font sizes were different: the smaller session had the smaller fonts. Apparently, I had changed window font sizes for some reason.

So in OS X, I just did Cmd-+ on the smaller sized session, and it snapped back into place.

I have modified @skafandri answer to avoid re-apply the datepicker constructor to all inputs with .datepicker_recurring_start class.

Here's the HTML:

<div id="content"></div>
<button id="cmd">add a datepicker</button>

Here's the JS:

$('#cmd').click(function() {
  var new_datepicker = $('<input type="text">').datepicker();
  $('#content').append('<br>a datepicker ').append(new_datepicker);
});

here's a working demo

Another potential way to do this for SQL Server, which has less reliance on the system tables (which are subject to change, version to version) is to use the INFORMATION_SCHEMA views:

select COLUMN_NAME, TABLE_NAME
from INFORMATION_SCHEMA.COLUMNS
where COLUMNPROPERTY(object_id(TABLE_SCHEMA+'.'+TABLE_NAME), COLUMN_NAME, 'IsIdentity') = 1
order by TABLE_NAME 

Okay guys another sleek option is

Application.Context.ApplicationInfo.NonLocalizedLabel

verified for hard coded android label on application element.

<application android:label="Big App"></application>

Reference: http://developer.android.com/reference/android/content/pm/PackageItemInfo.html#nonLocalizedLabel

In your new code,

int func(int *B){
    *B[0] = 5;
}

B is a pointer to int, thus B[0] is an int, and you can't dereference an int. Just remove the *,

int func(int *B){
    B[0] = 5;
}

and it works.

In the initialisation

int B[10] = {NULL};

you are initialising anint with a void* (NULL). Since there is a valid conversion from void* to int, that works, but it is not quite kosher, because the conversion is implementation defined, and usually indicates a mistake by the programmer, hence the compiler warns about it.

int B[10] = {0};

is the proper way to 0-initialise an int[10].

Here's another method for generating a random string:

SELECT SUBSTRING(MD5(RAND()) FROM 1 FOR 8) AS myrandomstring

If you're getting this error from Netbeans (7.2+) then it means that your separately installed version of Subversion is higher than the version in netbeans. In my case Netbeans (v7.3.1) had SVN v1.7 and I'd just upgraded my SVN to v1.8.

If you look in Tools > Options > Miscellaneous (tab) > Versioning (tab) > Subversion (pane), set the Preferred Client = CLI, then you can set the path the the installed SVN which for me was C:\Program Files\TortoiseSVN\bin.

More can be found on the Netbeans Subversion Clients FAQ.

I created a directive for this (angular stable 1.0.8)

<input type="text" input-disabled="editableInput" />
<button ng-click="editableInput = !editableInput">enable/disable</button>

app.controller("myController", function(){
  $scope.editableInput = false;
});

app.directive("inputDisabled", function(){
  return function(scope, element, attrs){
    scope.$watch(attrs.inputDisabled, function(val){
      if(val)
        element.removeAttr("disabled");
      else
        element.attr("disabled", "disabled");
    });
  }
});

Just a note on Brian's answer below, the first assignment to outlist can also be an append statement so you could also do something like this:

resultsa <- list(1,2,3,4,5)
resultsb <- list(6,7,8,9,10)
resultsc <- list(11,12,13,14,15)

outlist <- list()
outlist <- append(outlist,list(resultsa))
outlist <- append(outlist, list(resultsb))
outlist <- append(outlist, list(resultsc))

This is sometimes helpful if you want to build a list from scratch in a loop.

Add a DoEvents function inside the loop, see below.

You may also want to ensure that the Status bar is visible to the user and reset it when your code completes.

Sub ProgressMeter()

Dim booStatusBarState As Boolean
Dim iMax As Integer
Dim i As Integer

iMax = 10000

    Application.ScreenUpdating = False
''//Turn off screen updating

    booStatusBarState = Application.DisplayStatusBar
''//Get the statusbar display setting

    Application.DisplayStatusBar = True
''//Make sure that the statusbar is visible

    For i = 1 To iMax ''// imax is usually 30 or so
        fractionDone = CDbl(i) / CDbl(iMax)
        Application.StatusBar = Format(fractionDone, "0%") & " done..."
        ''// or, alternatively:
        ''// statusRange.value = Format(fractionDone, "0%") & " done..."
        ''// Some code.......

        DoEvents
        ''//Yield Control

    Next i

    Application.DisplayStatusBar = booStatusBarState
''//Reset Status bar display setting

    Application.StatusBar = False
''//Return control of the Status bar to Excel

    Application.ScreenUpdating = True
''//Turn on screen updating

End Sub

In SQL Server direct division of two integer returns integer even if the result should be the float. There is an example below to get it across:

--1--
declare @weird_number_float float
set @weird_number_float=22/7
select @weird_number_float

--2--
declare @weird_number_decimal decimal(18,10)
set @weird_number_decimal=22/7 
select @weird_number_decimal

--3--
declare @weird_number_numeric numeric
set @weird_number_numeric=22/7 
select @weird_number_numeric

--Right way

declare @weird_number float
set @weird_number=cast(22 as float)/cast(7 as float)
select @weird_number

Just last block will return the 3,14285714285714. In spite of the second block defined with right precision the result will be 3.00000.

Posting it here as it might help others. In string it might be necessary to pass the quotes to jq. To do the following with jq:

.items[] | select(.name=="string")

in bash you could do

EMAILID=$1
projectID=$(cat file.json | jq -r '.resource[] | select(.username=='\"$EMAILID\"') | .id')

essentially escaping the quotes and passing it on to jq

if the current thread is killed and you use Thread.Sleep and it is executing then you might get a ThreadAbortException. With Task.Delay you can always provide a cancellation token and gracefully kill it. Thats one reason I would choose Task.Delay. see http://social.technet.microsoft.com/wiki/contents/articles/21177.visual-c-thread-sleep-vs-task-delay.aspx

I also agree efficiency is not paramount in this case.

You just need to:

Step 1: Go home directory of C:\ with typing cd.. (2 times)

Step 2: It appears now C:\>

Step 3: Type dir Windows\System32\run

That's all, it shows complete files & folder details inside target folder.

Details: I used Windows\System32\com folder as example, you should type your own folder name etc. Windows\System32\run

Sometimes the column you are looking for may be part of the name of many other things that you are not interested in.

For example I was recently looking for a column called "BQR", which also forms part of many other columns such as "BQR_OWNER", "PROP_BQR", etc.

So I would like to have the checkbox that word processors have to indicate "Whole words only".

Unfortunately LIKE has no such functionality, but REGEXP_LIKE can help.

SELECT *
  FROM user_source
 WHERE regexp_like(text, '(\s|\.|,|^)bqr(\s|,|$)');

This is the regular expression to find this column and exclude the other columns with "BQR" as part of the name:

(\s|\.|,|^)bqr(\s|,|$)

The regular expression matches white-space (\s), or (|) period (.), or (|) comma (,), or (|) start-of-line (^), followed by "bqr", followed by white-space, comma or end-of-line ($).

And this works for me:

$(function () {
    $('#datetimepicker5').datetimepicker({
        format: 'HH:mm'
    });
});

just posting in case anyone else has the same error...

I was using 'await' outside of an 'async' function and for whatever reason that results in a 'missing ) after argument list' error.

The solution was to make the function asynchronous

function functionName(args) {}

becomes

async function functionName(args) {}

You need to make both your method - printMenu() and getUserChoice() static, as you are directly invoking them from your static main method, without creating an instance of the class, those methods are defined in. And you cannot invoke a non-static method without any reference to an instance of the class they are defined in.

Alternatively you can change the method invocation part to:

BookStoreApp2 bookStoreApp = new BookStoreApp2();
bookStoreApp.printMenu();
bookStoreApp.getUserChoice();

Use break.

Unrelated to your question, I see in your code the line:

Violated = !(name.firstname == null) ? false : true;

In this line, you take a boolean value (name.firstname == null). Then, you apply the ! operator to it. Then, if the value is true, you set Violated to false; otherwise to true. So basically, Violated is set to the same value as the original expression (name.firstname == null). Why not use that, as in:

Violated = (name.firstname == null);

To complete @cpu-100 answer,

in case you don't want to enable/use web interface, you can create a new credentials using command line like below and use it in your code to connect to RabbitMQ.

$ rabbitmqctl add_user YOUR_USERNAME YOUR_PASSWORD
$ rabbitmqctl set_user_tags YOUR_USERNAME administrator
$ rabbitmqctl set_permissions -p / YOUR_USERNAME ".*" ".*" ".*"

    file = open("path/of/file/(optional)/filename.txt", "w") #a=append,w=write,r=read
    any_string = "Hello\nWorld"
    file.write(any_string)
    file.close()

This page has a table of string constants including vbCrLf

vbCrLf | Chr(13) & Chr(10) | Carriage return–linefeed combination

If you find the notation awkward, maybe the -R-option does help. It outpouts the date in RFC 2822 format. So you won't need all those identifiers: date -d @1278999698 -R. Another possibility is to output the date in seconds in your locale: date -d @1278999698 +%c. Should be easy to remember. :-)

Here's a nice trick to read JSON from s3:

import json, boto3
s3 = boto3.resource("s3").Bucket("bucket")
json.load_s3 = lambda f: json.load(s3.Object(key=f).get()["Body"])
json.dump_s3 = lambda obj, f: s3.Object(key=f).put(Body=json.dumps(obj))

Now you can use json.load_s3 and json.dump_s3 with the same API as load and dump

data = {"test":0}
json.dump_s3(data, "key") # saves json to s3://bucket/key
data = json.load_s3("key") # read json from s3://bucket/key

I'm doing something very similar it's generic, no need to compute something specific for your code. Just check the remarks on the code:

Some browser differences to be aware of:

Given the CSS:

div#a { ... }
div#b, div#c { ... }

and given InsDel's example, classes will have 2 classes in FF and 3 classes in IE7.

My example illustrates this:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
    <style>
    div#a { }
    div#b, div#c { }
    </style>
    <script>
    function PrintRules() {
    var rules = document.styleSheets[0].rules || document.styleSheets[0].cssRules
        for(var x=0;x<rules.length;x++) {
            document.getElementById("rules").innerHTML += rules[x].selectorText + "<br />";
        }
    }
    </script>
</head>
<body>
    <input onclick="PrintRules()" type="button" value="Print Rules" /><br />
    RULES:
    <div id="rules"></div>
</body>
</html>

Try use Gson library to convert objects to Json

Example with servlets :

  List<Party> parties = bean.getPartiesByIncidentId(incidentId);
        String json = "";
        try {
            json = new Gson().toJson(parties);
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        response.setContentType("application/json");
        response.setCharacterEncoding("UTF-8");
        response.getWriter().write(json);

Use the beforeSend callback to add a HTTP header with the authentication information like so:

var username = $("input#username").val();
var password = $("input#password").val();  

function make_base_auth(user, password) {
  var tok = user + ':' + password;
  var hash = btoa(tok);
  return "Basic " + hash;
}
$.ajax
  ({
    type: "GET",
    url: "index1.php",
    dataType: 'json',
    async: false,
    data: '{}',
    beforeSend: function (xhr){ 
        xhr.setRequestHeader('Authorization', make_base_auth(username, password)); 
    },
    success: function (){
        alert('Thanks for your comment!'); 
    }
});

In my case I just needed to remove Homebrew's executable using:

sudo rm -f `which brew`

Then reinstall Homebrew:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

You can use until():

LocalDate independenceDay = LocalDate.of(2014, Month.JULY, 4);
LocalDate christmas = LocalDate.of(2014, Month.DECEMBER, 25);

System.out.println("Until christmas: " + independenceDay.until(christmas));
System.out.println("Until christmas (with crono): " + independenceDay.until(christmas, ChronoUnit.DAYS));

Just convert it to a date using NSDateFormatter and the "h:mm a" format and convert it back to a string using the "HH:mm" format. Check out this date formatting guide to familiarize yourself with this material.

let dateAsString = "6:35 PM"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "h:mm a"
let date = dateFormatter.dateFromString(dateAsString)

dateFormatter.dateFormat = "HH:mm"
let date24 = dateFormatter.stringFromDate(date!)

To fix this you need add your machine name in the /etc/hosts file to point to localhost(127.0.0.1).

You can find your machine name by running the following command:

$ hostname
macbook-pro

From the output above you know your hostname is "macbook-pro". Edit "/etc/hosts" file and add that name at the end of line that lists 127.0.0.1

127.0.0.1 localhost macbook-pro

Save the file.

Now you IntelliJ should be able to start your server.

The methods do not have to give the same answers. That depends on which objects/classes you call them.

If you are implementing your own classes which you know you want to compare at some stage, you may have them implement the Comparable interface and implement the compareTo() method accordingly.

If you are using some classes from an API which do not implement the Comparable interface, but you still want to compare them. I.e. for sorting. You may create your own class which implements the Comparator interface and in its compare() method you implement the logic.

I haven't seen this exact answer:

dict['key'] = value

You can even do this to object attributes. Make them into a dictionary by doing this:

dict = vars(obj)

Then you can manipulate the object attributes like you would a dictionary:

dict['attribute'] = value

You could use a classmethod or staticmethod

class Paul(object):
    elems = []

    @classmethod
    def addelem(cls, e):
        cls.elems.append(e)

    @staticmethod
    def addelem2(e):
        Paul.elems.append(e)

Paul.addelem(1)
Paul.addelem2(2)

print(Paul.elems)

classmethod has advantage that it would work with sub classes, if you really wanted that functionality.

module is certainly best though.

If you use Custom Actions written in .NET as part of your MSI installer then you have another problem.

The 'shim' that runs these custom actions is always 32bit then your custom action will run 32bit as well, despite what target you specify.

More info & some ninja moves to get around (basically change the MSI to use the 64 bit version of this shim)

The OP has not defined the scope of testing, however, simple (gross) 'smoke testing' an install should be performed before any time is invested with functionality testing.

How to test if application is installed ('smoke-test')

Log into the mosquitto server's command line and type:

mosquitto

If mosquitto is installed the machine will return:

 mosquitto version 1.4.8 (build date Wed, date of installation) starting
 Using default config.
 Opening ipv4 listen socket on port 1883

Something like this could be used, and still maintaining meanings of return (to return control signals) and echo (to return information) and logging statements (to print debug/info messages).

v_verbose=1

In here, I'm redirecting debug messages to separate file, that is watched by tail, and if there is any changes then printing the change, trap is used to make sure that background process always ends.

This behavior can also be achieved using redirection to /dev/stderr, But difference can be seen at the time of piping output of one command to input of other command.

I use the following with python 3.8

string4 = f'{string1}{string2}{string3}'

For Bootstrap 4.0 there is a change

See the docs: https://getbootstrap.com/docs/4.0/utilities/display/

In order to hide the content on mobile and display on the bigger devices you have to use the following classes:

d-none d-sm-block

The first class set display none all across devices and the second one display it for devices "sm" up (you could use md, lg, etc. instead of sm if you want to show on different devices.

I suggest to read about that before migration:

https://getbootstrap.com/docs/4.0/migration/#responsive-utilities

This method helped me doing this task

document.forms['YourFormNameHere'].elements['NameofFormField'].value = "YourValue"
document.forms['YourFormNameHere'].submit();

you can still use

String Item = getIntent().getExtras().getString("name");

in the fragment, you just need call getActivity() first:

String Item = getActivity().getIntent().getExtras().getString("name");

This saves you having to write some code.

System.out.println(LocalDate.now().format(DateTimeFormatter.ofPattern("dd.MMMM yyyy")));

The above answer shows it for today

If you use the OOP method of inserting, you don't need to worry about mass-action/fillable properties:

$user = new User;
$user->username = 'Stevo';
$user->email = '[email protected]';
$user->password = '45678';
$user->save();

Actually...

To hide an absolute positioned element, the container position must be anything except for static. It can be relative or fixed in addition to absolute.

As an extension to what John said, if you want to extract the string representation and store it in a std::string do this:

#include <sstream>    
// ...
// Suppose a class A
A a;
std::stringstream sstream;
sstream << a;
std::string s = sstream.str(); // or you could use sstream >> s but that would skip out whitespace

std::stringstream is located in the <sstream> header.

There is also a good keyboard shortcut key just click n select the Class / Package which you want to rename and press ALT + two times R or Shift+ F6

which reflect :-> Refactor menu and Rename function in Android Studio. After rename the existing package it shows in bottom side where the effect of this reflection / rename if you click on Refector button it will change the Class name / Package name where is used in whole Project.

According to BOL:

Indexed views and indexes on computed columns store results in the database for later reference. The stored results are valid only if all connections referring to the indexed view or indexed computed column can generate the same result set as the connection that created the index.

In order to create a table with a persisted, computed column, the following connection settings must be enabled:

SET ANSI_NULLS ON
SET ANSI_PADDING ON
SET ANSI_WARNINGS ON
SET ARITHABORT ON
SET CONCAT_NULL_YIELDS_NULL ON
SET NUMERIC_ROUNDABORT ON
SET QUOTED_IDENTIFIER ON

These values are set on the database level and can be viewed using:

SELECT 
    is_ansi_nulls_on,
    is_ansi_padding_on,
    is_ansi_warnings_on,
    is_arithabort_on,
    is_concat_null_yields_null_on,
    is_numeric_roundabort_on,
    is_quoted_identifier_on
FROM sys.databases

However, the SET options can also be set by the client application connecting to SQL Server.

A perfect example is SQL Server Management Studio which has the default values for SET ANSI_NULLS and SET QUOTED_IDENTIFIER both to ON. This is one of the reasons why I could not initially duplicate the error you posted.

Anyway, to duplicate the error, try this (this will override the SSMS default settings):

SET ANSI_NULLS ON
SET ANSI_PADDING OFF
SET ANSI_WARNINGS OFF
SET ARITHABORT OFF
SET CONCAT_NULL_YIELDS_NULL ON 
SET NUMERIC_ROUNDABORT OFF
SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE T1 (
    ID INT NOT NULL,
    TypeVal AS ((1)) PERSISTED NOT NULL
) 

You can fix the test case above by using:

SET ANSI_PADDING ON
SET ANSI_WARNINGS ON

I would recommend tweaking these two settings in your script before the creation of the table and related indexes.

It works for me:

>>> def pyth_test (x1, x2):
...     print x1 + x2
...
>>> pyth_test(1,2)
3

Make sure you define the function before you call it.

The reason csv doesn't support that is because variable-length lines are not really supported on most filesystems. What you should do instead is collect all the data in lists, then call zip() on them to transpose them after.

>>> l = [('Result_1', 'Result_2', 'Result_3', 'Result_4'), (1, 2, 3, 4), (5, 6, 7, 8)]
>>> zip(*l)
[('Result_1', 1, 5), ('Result_2', 2, 6), ('Result_3', 3, 7), ('Result_4', 4, 8)]

With TypeScript 2.9.+ you can simply import JSON files with typesafety and intellisense like this:

import colorsJson from '../colors.json'; // This import style requires "esModuleInterop", see "side notes"
console.log(colorsJson.primaryBright);

Make sure to add these settings in the compilerOptions section of your tsconfig.json (documentation):

"resolveJsonModule": true,
"esModuleInterop": true,

Side notes:

• Typescript 2.9.0 has a bug with this JSON feature, it was fixed with 2.9.2
• The esModuleInterop is only necessary for the default import of the colorsJson. If you leave it set to false then you have to import it with import * as colorsJson from '../colors.json'

believe there should be a way in accessing file system.

Include node.d.ts using npm i @types/node. And then create a new tsconfig.json file (npx tsc --init) and create a .ts file as followed:

import fs from 'fs';
fs.readFileSync('foo.txt','utf8');

You can use other functions in fs as well : https://nodejs.org/api/fs.html

To make angular ui $modal work with bootstrap 3 you need to overwrite the styles

.modal {
    display: block;
}
.modal-body:before,
.modal-body:after {
    display: table;
    content: " ";
}
.modal-header:before,
.modal-header:after {
    display: table;
    content: " ";
}

(The last ones are necessary if you use custom directives) and encapsulate the html with

<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
      <h4 class="modal-title">Modal title</h4>
    </div>
    <div class="modal-body">
      ...
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      <button type="button" class="btn btn-primary">Save changes</button>
    </div>
  </div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->

If you want to pass the variable to your proxy backend, you have to set it with the proxy module.

location / {
    proxy_pass                      http://example.com;
    proxy_set_header                Host example.com;
    proxy_set_header                HTTP_Country-Code $geoip_country_code;
    proxy_pass_request_headers      on;
}

And now it's passed to the proxy backend.

What's the pythonic way to use getters and setters?

The "Pythonic" way is not to use "getters" and "setters", but to use plain attributes, like the question demonstrates, and del for deleting (but the names are changed to protect the innocent... builtins):

value = 'something'

obj.attribute = value  
value = obj.attribute
del obj.attribute

If later, you want to modify the setting and getting, you can do so without having to alter user code, by using the property decorator:

class Obj:
    """property demo"""
    #
    @property            # first decorate the getter method
    def attribute(self): # This getter method name is *the* name
        return self._attribute
    #
    @attribute.setter    # the property decorates with `.setter` now
    def attribute(self, value):   # name, e.g. "attribute", is the same
        self._attribute = value   # the "value" name isn't special
    #
    @attribute.deleter     # decorate with `.deleter`
    def attribute(self):   # again, the method name is the same
        del self._attribute

(Each decorator usage copies and updates the prior property object, so note that you should use the same name for each set, get, and delete function/method.

After defining the above, the original setting, getting, and deleting code is the same:

obj = Obj()
obj.attribute = value  
the_value = obj.attribute
del obj.attribute

You should avoid this:

def set_property(property,value):  
def get_property(property):  

Firstly, the above doesn't work, because you don't provide an argument for the instance that the property would be set to (usually self), which would be:

class Obj:

    def set_property(self, property, value): # don't do this
        ...
    def get_property(self, property):        # don't do this either
        ...

Secondly, this duplicates the purpose of two special methods, __setattr__ and __getattr__.

Thirdly, we also have the setattr and getattr builtin functions.

setattr(object, 'property_name', value)
getattr(object, 'property_name', default_value)  # default is optional

The @property decorator is for creating getters and setters.

For example, we could modify the setting behavior to place restrictions the value being set:

class Protective(object):

    @property
    def protected_value(self):
        return self._protected_value

    @protected_value.setter
    def protected_value(self, value):
        if acceptable(value): # e.g. type or range check
            self._protected_value = value

In general, we want to avoid using property and just use direct attributes.

This is what is expected by users of Python. Following the rule of least-surprise, you should try to give your users what they expect unless you have a very compelling reason to the contrary.

Demonstration

For example, say we needed our object's protected attribute to be an integer between 0 and 100 inclusive, and prevent its deletion, with appropriate messages to inform the user of its proper usage:

class Protective(object):
    """protected property demo"""
    #
    def __init__(self, start_protected_value=0):
        self.protected_value = start_protected_value
    # 
    @property
    def protected_value(self):
        return self._protected_value
    #
    @protected_value.setter
    def protected_value(self, value):
        if value != int(value):
            raise TypeError("protected_value must be an integer")
        if 0 <= value <= 100:
            self._protected_value = int(value)
        else:
            raise ValueError("protected_value must be " +
                             "between 0 and 100 inclusive")
    #
    @protected_value.deleter
    def protected_value(self):
        raise AttributeError("do not delete, protected_value can be set to 0")

(Note that __init__ refers to self.protected_value but the property methods refer to self._protected_value. This is so that __init__ uses the property through the public API, ensuring it is "protected".)

And usage:

>>> p1 = Protective(3)
>>> p1.protected_value
3
>>> p1 = Protective(5.0)
>>> p1.protected_value
5
>>> p2 = Protective(-5)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in __init__
  File "<stdin>", line 15, in protected_value
ValueError: protectected_value must be between 0 and 100 inclusive
>>> p1.protected_value = 7.3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 17, in protected_value
TypeError: protected_value must be an integer
>>> p1.protected_value = 101
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 15, in protected_value
ValueError: protectected_value must be between 0 and 100 inclusive
>>> del p1.protected_value
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 18, in protected_value
AttributeError: do not delete, protected_value can be set to 0

Do the names matter?

Yes they do. .setter and .deleter make copies of the original property. This allows subclasses to properly modify behavior without altering the behavior in the parent.

class Obj:
    """property demo"""
    #
    @property
    def get_only(self):
        return self._attribute
    #
    @get_only.setter
    def get_or_set(self, value):
        self._attribute = value
    #
    @get_or_set.deleter
    def get_set_or_delete(self):
        del self._attribute

Now for this to work, you have to use the respective names:

obj = Obj()
# obj.get_only = 'value' # would error
obj.get_or_set = 'value'  
obj.get_set_or_delete = 'new value'
the_value = obj.get_only
del obj.get_set_or_delete
# del obj.get_or_set # would error

I'm not sure where this would be useful, but the use-case is if you want a get, set, and/or delete-only property. Probably best to stick to semantically same property having the same name.

Conclusion

Start with simple attributes.

If you later need functionality around the setting, getting, and deleting, you can add it with the property decorator.

Avoid functions named set_... and get_... - that's what properties are for.

Application.Exit() kills your application but there are some instances that it won't close the application.

End is better than Application.Exit().

This is quite late but anyone going through the same problem might benefit from this answer.First try to add browser by running below command ionic platform add browser and then run command ionic run browser.

which is the difference between ionic serve and ionic run browser?

Ionic serve - runs your app as a website (meaning it doesn't have any Cordova capabilities). Ionic run browser - runs your app in the Cordova browser platform, which will inject cordova.js and any plugins that have browser capabilities

You can refer this link to know more difference between ionic serve and ionic run browser command

Update

From Ionic 3 this command has been changed. Use the command below instead;

ionic cordova platform add browser

ionic cordova run browser

You can find out which version of ionic you are using by running: ionic --version

Also you can use Kotlinx features

val hView = nav_view.getHeaderView(0)
hView.textViewName.text = "lorem ipsum"
hView.imageView.setImageResource(R.drawable.ic_menu_gallery)

A very simple solution considering you have object A and B:

foreach($objB AS $var=>$value){
    $objA->$var = $value;
}

That's all. You now have objA with all values from objB.

In addition to previous answers, you should be aware that there are strange behaviours associated with -0.0f and +0.0f (they are == but not equals) and Float.NaN (it is equals but not ==) (hope I've got that right - argh, don't do it!).

Edit: Let's check!

import static java.lang.Float.NaN;
public class Fl {
    public static void main(String[] args) {
        System.err.println(          -0.0f   ==              0.0f);   // true
        System.err.println(new Float(-0.0f).equals(new Float(0.0f))); // false
        System.err.println(            NaN   ==               NaN);   // false
        System.err.println(new Float(  NaN).equals(new Float( NaN))); // true
    }
}

Let's say you have the following directory structure where you want to generate javadocs on file1.java and file2.java (package com.test), with the javadocs being placed in C:\javadoc\test:

C:\
|
+--javadoc\
|  |
|  +--test\
|
+--projects\
   |
   +--com\
      |
      +--test\
         |
         +--file1.java
         +--file2.java

In the command terminal, navigate to the root of your package: C:\projects. If you just want to generate the standard javadocs on all the java files inside the project, run the following command (for multiple packages, separate the package names by spaces):

C:\projects> javadoc -d [path to javadoc destination directory] [package name]

C:\projects> javadoc -d C:\javadoc\test com.test

If you want to run javadocs from elsewhere, you'll need to specify the sourcepath. For example, if you were to run javadocs in in C:\, you would modify the command as such:

C:\> javadoc -d [path to javadoc destination directory] -sourcepath [path to package directory] [package name]

C:\> javadoc -d C:\javadoc\test -sourcepath C:\projects com.test

If you want to run javadocs on only selected .java files, then add the source filenames separated by spaces (you can use an asterisk (*) for a wildcard). Make sure to include the path to the files:

C:\> javadoc -d [path to javadoc destination directory] [source filenames]

C:\> javadoc -d C:\javadoc\test C:\projects\com\test\file1.java

More information/scenarios can be found here.

For casting varchar fields/values to number format can be little hack used:

SELECT (`PROD_CODE` * 1) AS `PROD_CODE` FROM PRODUCT`

This is a similar way I'm using here to generate an unique error code, based on Anton Purin answer, but relying on the more appropriate org.apache.commons.text.RandomStringGenerator instead of the (once, not anymore) deprecated org.apache.commons.lang3.RandomStringUtils:

@Singleton
@Component
public class ErrorCodeGenerator implements Supplier<String> {

    private RandomStringGenerator errorCodeGenerator;

    public ErrorCodeGenerator() {
        errorCodeGenerator = new RandomStringGenerator.Builder()
                .withinRange('0', 'z')
                .filteredBy(t -> t >= '0' && t <= '9', t -> t >= 'A' && t <= 'Z', t -> t >= 'a' && t <= 'z')
                .build();
    }

    @Override
    public String get() {
        return errorCodeGenerator.generate(8);
    }

}

All advices about collision still apply, please be aware of them.

This works for me

webView.setOnTouchListener(new View.OnTouchListener() {
                            @Override
                            public boolean onTouch(View v, MotionEvent event) {
                                // Do what you want
                                return false;
                            }
                        });

The syntax is

EXEC mySchema.myPackage.myProcedure@myRemoteDB( 'someParameter' );

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

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

as mentioned in the git manual:

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

You can also use this syntax: (in column D to concatenate A, B, and C)

=A2 & " """ & B2 & """ " & C2

On Windows, you can find it under.

%USERPROFILE%\AppData\Roaming\Subversion\auth\svn.simple
(same as below)
%APPDATA%\Roaming\Subversion\auth\svn.simple

There may be multiple files under this directory, depending upon the repos you are contributing to. You can assume this as one file for each svn server. You can open the file with any text editor and make sure you are going to delete the correct file.

I get the same error in Chrome after pasting code copied from jsfiddle.

If you select all the code from a panel in jsfiddle and paste it into the free text editor Notepad++, you should be able to see the problem character as a question mark "?" at the very end of your code. Delete this question mark, then copy and paste the code from Notepad++ and the problem will be gone.

(I am using JupyterLab with Julia)

First thing is that Jupyter lab from my previous use offers more 'themes' which is great on the eyes, and also fontsize changes independent of the browser, so that makes it closer to that of an IDE. There are some specifics I like such as changing the 'code font size' and leaving the interface font size to be the same.

Major features that are great is

• the drag and drop of cells so that you can easily rearrange the code
• collapsing cells with a single mouse click and a small mark to remind of their placement

What is paramount though is the ability to have split views of the tabs and the terminal. If you use Emacs, then you probably enjoyed having multiple buffers with horizontal and vertical arrangements with one of them running a shell (terminal), and with jupyterlab this can be done, and the arrangement is made with drags and drops which in Emacs is typically done with sets of commands.

(I do not believe that there is a learning curve added to those that have not used the 'notebook' original version first. You can dive straight into this IDE experience)

I have tried to compile everything that needs to be done for self-hosting icons in my answer. You need to follow these 4 simple steps.

1. Open the iconfont folder of the materialize repository

   link- https://github.com/google/material-design-icons/tree/master/iconfont

2. Download these three icons files ->

   MaterialIcons-Regular.woff2 - format('woff2')

   MaterialIcons-Regular.woff - format('woff')

   MaterialIcons-Regular.ttf - format('truetype');

   Note- After Download you can rename it to whatever you like.

3. Now, go to your CSS and add this code

@font-face {
  font-family: 'Material Icons';
  font-style: normal;
  font-weight: 400;
  src: url(MaterialIcons-Regular.eot); /* For IE6-8 */
  src: local('Material Icons'),
       local('MaterialIcons-Regular'),
       url(MaterialIcons-Regular.woff2) format('woff2'),
       url(MaterialIcons-Regular.woff) format('woff'),
       url(MaterialIcons-Regular.ttf) format('truetype');
}

.material-icons {
  font-family: 'Material Icons';
  font-weight: normal;
  font-style: normal;
  font-size: 24px;  /* Preferred icon size */
  display: inline-block;
  line-height: 1;
  text-transform: none;
  letter-spacing: normal;
  word-wrap: normal;
  white-space: nowrap;
  direction: ltr;

  /* Support for all WebKit browsers. */
  -webkit-font-smoothing: antialiased;
  /* Support for Safari and Chrome. */
  text-rendering: optimizeLegibility;

  /* Support for Firefox. */
  -moz-osx-font-smoothing: grayscale;

  /* Support for IE. */
  font-feature-settings: 'liga';
}

Note : The address provided in src:url(...) should be with respect to the 'CSS File' and not the index.html file. For example it can be src : url(../myicons/MaterialIcons-Regular.woff2)

4. You are ready to use now and here is how it can be done in HTML

<i class="material-icons">face</i>

The best solution for your browser load time would be to use a server side script to join them all together into one big .js file. Make sure to gzip/minify the final version. Single request - nice and compact.

Alternatively, you can use DOM to create a <script> tag and set the src property on it then append it to the <head>. If you need to wait for that functionality to load, you can make the rest of your javascript file be called from the load event on that script tag.

This function is based on the functionality of jQuery $.getScript()

function loadScript(src, f) {
  var head = document.getElementsByTagName("head")[0];
  var script = document.createElement("script");
  script.src = src;
  var done = false;
  script.onload = script.onreadystatechange = function() { 
    // attach to both events for cross browser finish detection:
    if ( !done && (!this.readyState ||
      this.readyState == "loaded" || this.readyState == "complete") ) {
      done = true;
      if (typeof f == 'function') f();
      // cleans up a little memory:
      script.onload = script.onreadystatechange = null;
      head.removeChild(script);
    }
  };
  head.appendChild(script);
}

// example:
loadScript('/some-other-script.js', function() { 
   alert('finished loading');
   finishSetup();
 });

An easy fix is to delete your publish profile and create a fresh one.

when you right click on your solution and select publish, you have a profile set. delete this and create a new one.

this will fix it.

I had this problem from switching from 2010 to 2012

Note the potential for an out-of-range index with "i+3". You could do something like:

with open("file.txt", "r") as f:
    searchlines = f.readlines()
j=len(searchlines)-1
for i, line in enumerate(searchlines):
    if "searchphrase" in line: 
        k=min(i+3,j)
        for l in searchlines[i:k]: print l,
        print

Edit: maybe not necessary. I just tested some examples. x[y] will give errors if y is out of range, but x[y:z] doesn't seem to give errors for out of range values of y and z.

a version similar to C. Dragon's, but for if you only need a single replacement:

int n = myText.IndexOf(oldValue, System.StringComparison.InvariantCultureIgnoreCase);
if (n >= 0)
{
    myText = myText.Substring(0, n)
        + newValue
        + myText.Substring(n + oldValue.Length);
}

I had a similar problem with é char... I think the comment "it's possible that the text you're feeding it isn't UTF-8" is probably close to the mark here. I have a feeling the default collation in my instance was something else until I realized and changed to utf8... problem is the data was already there, so not sure if it converted the data or not when i changed it, displays fine in mysql workbench. End result is that php will not json encode the data, just returns false. Doesn't matter what browser you use as its the server causing my issue, php will not parse the data to utf8 if this char is present. Like i say not sure if it is due to converting the schema to utf8 after data was present or just a php bug. In this case use json_encode(utf8_encode($string));

I found the solution, it is a good library.

Cross platform 256bit AES encryption / decryption.

This project contains the implementation of 256 bit AES encryption which works on all the platforms (C#, iOS, Android). One of the key objective is to make AES work on all the platforms with simple implementation.

Platforms Supported: iOS , Android , Windows (C#).

You can take a reference on the control on the ItemCreated event, and then use it later.

Basically VOLUME and -v option are almost equal. These mean 'mount specific directory on your container'. For example, VOLUME /data and -v /data is exactly same meaning. If you run the image that have VOLUME /data or with -v /data option, /data directory is mounted your container. This directory doesn't belong to your container.

Imagine that You add some files to /data on the container, then commit the container into new image. There isn't any files on data directory because mounted /data directory is belong to original container.

$ docker run -it -v /data --name volume ubuntu:14.04 bash
root@2b5e0f2d37cd:/# cd /data
root@2b5e0f2d37cd:/data# touch 1 2 3 4 5 6 7 8 9
root@2b5e0f2d37cd:/data# cd /tmp
root@2b5e0f2d37cd:/tmp# touch 1 2 3 4 5 6 7 8 9
root@2b5e0f2d37cd:/tmp# exit
exit

$ docker commit volume nacyot/volume  
835cfe3d8d159622507ba3256bb1c0b0d6e7c1419ae32751ad0f925c40378945
nacyot $ docker run -it nacyot/volume
root@dbe335c7e64d:/# cd /data
root@dbe335c7e64d:/data# ls
root@dbe335c7e64d:/data# cd /tmp
root@dbe335c7e64d:/tmp# ls
1  2  3  4  5  6  7  8  9
root@dbe335c7e64d:/tmp# 
root@dbe335c7e64d:/tmp# 

This mounted directory like /data is used to store data that is not belong to your application. And you can predefine the data directory that is not belong to the container by using VOLUME.

A difference between Volume and -v option is that you can use -v option dynamically on starting container. It mean you can mount some directory dynamically. And another difference is that you can mount your host directory on your container by using -v

The setting for the list throttle

• Open the SharePoint Central Administration,
• go to Application Management --> Manage Web Applications
• Click to select the web application that hosts your list (eg. SharePoint - 80)
• At the Ribbon, select the General Settings and select Resource Throttling
• Then, you can see the 5000 List View Threshold limit and you can edit the value you want.
• Click OK to save it.

BookTitle have a Composite key. so if the key of BookTitle is referenced as a foreign key you have to bring the complete composite key.

So to resolve the problem you need to add the complete composite key in the BookCopy. So add ISBN column as well. and they at the end.

foreign key (ISBN, Title) references BookTitle (ISBN, Title)

Here's a good metrics plugin that displays number of lines of code and much more:

http://metrics.sourceforge.net/

It says it requires Eclipse 3.1, although I imagine they mean 3.1+

Here's another metrics plugin that's been tested on Ganymede:

With all respect the most likely thing is that you are mistaken about why the click is being 'rejected'. Why do you think some program is trying to determine if it's human or not? The Robot class (have used it a lot) should send messages that the operating system has no way to distinguish from a user doing the click.

Visual Studio Community is same (almost) as professional edition. What differs is that VS community do not have TFS features, and the licensing is different. As stated by @Stefan.

The different versions on VS are compared here - https://www.visualstudio.com/en-us/products/compare-visual-studio-2015-products-vs

I found an excellent Chart.js plugin that does exactly what you want: https://github.com/emn178/Chart.PieceLabel.js

:::::HTML:::::

<input type="text" onkeypress="return lettersValidate(event)" />

Only letters no spaces

::::JS::::::::

// ===================== Allow - Only Letters ===============================================================

function lettersValidate(key) {
    var keycode = (key.which) ? key.which : key.keyCode;

    if ((keycode > 64 && keycode < 91) || (keycode > 96 && keycode < 123))  
    {     
           return true;    
    }
    else
    {
        return false;
    }
         
}
 

So I'm myself new to React and I found a way to do it.

This solution does not require any extra packages.

Step 1 ReactDocs

In the above docs they mention export in Shell and other options, the one I'll attempt to explain is using .env file

1.1 create Root/.env

#.env file
REACT_APP_SECRET_NAME=secretvaluehere123

Important notes it MUST start with REACT_APP_

1.2 Access ENV variable

#App.js file or the file you need to access ENV
<p>print env secret to HTML</p>
<pre>{process.env.REACT_APP_SECRET_NAME}</pre>

handleFetchData() { // access in API call
  fetch(`https://awesome.api.io?api-key=${process.env.REACT_APP_SECRET_NAME}`)
    .then((res) => res.json())
    .then((data) => console.log(data))
}

1.3 Build Env Issue

So after I did step 1.1|2 it was not working, then I found the above issue/solution. React read/creates env when is built so you need to npm run start every time you modify the .env file so the variables get updated.

If you are still interested in a javascript api to select both date and time data, have a look at these projects which are forks of bootstrap datepicker:

• Bootstrap Datetime Picker 1

• Bootstrap Datetime Picker 2

The first fork is a big refactor on the parsing/formatting codebase and besides providing all views to select date/time using mouse/touch, it also has a mask option (by default) which lets the user to quickly type the date/time based on a pre-specified format.

You could use a list comprehension:

def square(list):
    return [i ** 2 for i in list]

Or you could map it:

def square(list):
    return map(lambda x: x ** 2, list)

Or you could use a generator. It won't return a list, but you can still iterate through it, and since you don't have to allocate an entire new list, it is possibly more space-efficient than the other options:

def square(list):
    for i in list:
        yield i ** 2

Or you can do the boring old for-loop, though this is not as idiomatic as some Python programmers would prefer:

def square(list):
    ret = []
    for i in list:
        ret.append(i ** 2)
    return ret

Yes, it is a non-type parameter. You can have several kinds of template parameters

• Type Parameters.
  • Types
  • Templates (only classes and alias templates, no functions or variable templates)
• Non-type Parameters
  • Pointers
  • References
  • Integral constant expressions

What you have there is of the last kind. It's a compile time constant (so-called constant expression) and is of type integer or enumeration. After looking it up in the standard, i had to move class templates up into the types section - even though templates are not types. But they are called type-parameters for the purpose of describing those kinds nonetheless. You can have pointers (and also member pointers) and references to objects/functions that have external linkage (those that can be linked to from other object files and whose address is unique in the entire program). Examples:

Template type parameter:

template<typename T>
struct Container {
    T t;
};

// pass type "long" as argument.
Container<long> test;

Template integer parameter:

template<unsigned int S>
struct Vector {
    unsigned char bytes[S];
};

// pass 3 as argument.
Vector<3> test;

Template pointer parameter (passing a pointer to a function)

template<void (*F)()>
struct FunctionWrapper {
    static void call_it() { F(); }
};

// pass address of function do_it as argument.
void do_it() { }
FunctionWrapper<&do_it> test;

Template reference parameter (passing an integer)

template<int &A>
struct SillyExample {
    static void do_it() { A = 10; }
};

// pass flag as argument
int flag;
SillyExample<flag> test;

Template template parameter.

template<template<typename T> class AllocatePolicy>
struct Pool {
    void allocate(size_t n) {
        int *p = AllocatePolicy<int>::allocate(n);
    }
};

// pass the template "allocator" as argument. 
template<typename T>
struct allocator { static T * allocate(size_t n) { return 0; } };
Pool<allocator> test;

A template without any parameters is not possible. But a template without any explicit argument is possible - it has default arguments:

template<unsigned int SIZE = 3>
struct Vector {
    unsigned char buffer[SIZE];
};

Vector<> test;

Syntactically, template<> is reserved to mark an explicit template specialization, instead of a template without parameters:

template<>
struct Vector<3> {
    // alternative definition for SIZE == 3
};

simplifily, use:

pip install -r requirement.txt

it can install all listed in requirement file.

If somebody needed:

body -> form-data

Add field name as array

Just add profile to session configuration before client call. boto3.session.Session(profile_name='YOUR_PROFILE_NAME').client('cloudwatch')

The following should do what you want:

x <- data.frame(X1=sample(c(1:3,NaN), 200, replace=TRUE), X2=sample(c(4:6,NaN), 200, replace=TRUE))
head(x)
x <- replace(x, is.na(x), 0)
head(x)

The problem for me was that I had .rnd in my home directory but it was owned by root. Deleting it and reissuing the openssl command fixed this.

Here's another example that was tested, and will match search & replace patterns:

import fileinput
import sys

def replaceAll(file,searchExp,replaceExp):
    for line in fileinput.input(file, inplace=1):
        if searchExp in line:
            line = line.replace(searchExp,replaceExp)
        sys.stdout.write(line)

Example use:

replaceAll("/fooBar.txt","Hello\sWorld!$","Goodbye\sWorld.")

You can use base_path() to get the base of your application - and then just add your public folder to that:

$path = base_path().'/public';
return File::put($path , $data)

Note: Be very careful about allowing people to upload files into your root of public_html. If they upload their own index.php file, they will take over your site.
