There are two different ways of importing components in react and the recommended way is component way

1. Library way(not recommended)
2. Component way(recommended)

PFB detail explanation

Library way of importing

import { Button } from 'react-bootstrap';
import { FlatButton } from 'material-ui';

This is nice and handy but it does not only bundles Button and FlatButton (and their dependencies) but the whole libraries.

Component way of importing

One way to alleviate it is to try to only import or require what is needed, lets say the component way. Using the same example:

import Button from 'react-bootstrap/lib/Button';
import FlatButton from 'material-ui/lib/flat-button';

This will only bundle Button, FlatButton and their respective dependencies. But not the whole library. So I would try to get rid of all your library imports and use the component way instead.

If you are not using lot of components then it should reduce considerably the size of your bundled file.

That means your pom.xml has unresolved issues. Open the problems view solve accordingly. Then you will be able to run the test cases successfully without encountering the classnotfoundexception.

If you want to call functions on components from outside React, you can call them on the return value of renderComponent:

var Child = React.createClass({…});
var myChild = React.renderComponent(Child);
myChild.someMethod();

The only way to get a handle to a React Component instance outside of React is by storing the return value of React.renderComponent. Source.

= can be used when the subquery returns only 1 value.

When subquery returns more than 1 value, you will have to use IN:

select * 
from table
where id IN (multiple row query);

For example:

SELECT *
FROM Students
WHERE Marks = (SELECT MAX(Marks) FROM Students)   --Subquery returns only 1 value

SELECT *
FROM Students
WHERE Marks IN 
      (SELECT Marks 
       FROM Students 
       ORDER BY Marks DESC
       LIMIT 10)                       --Subquery returns 10 values

You can easily reach them by using the Run window and entering:

shell:startup

and

shell:common startup

Source.

Use a FULL OUTER JOIN:

select 
   a.col_a,
   a.col_b,
   b.col_c
from
   (select col_a,col_bfrom tab1) a
join 
   (select col_a,col_cfrom tab2) b 
on a.col_a= b.col_a

With the use of the bootstrap 4 utilities you could horizontally center an element itself by setting the horizontal margins to 'auto'.

To set the horizontal margins to auto you can use mx-auto . The m refers to margin and the x will refer to the x-axis (left+right) and auto will refer to the setting. So this will set the left margin and the right margin to the 'auto' setting. Browsers will calculate the margin equally and center the element. The setting will only work on block elements so the display:block needs to be added and with the bootstrap utilities this is done by d-block.

<button type="submit" class="btn btn-primary mx-auto d-block">Submit</button>

You can consider all browsers to fully support auto margin settings according to this answer Browser support for margin: auto so it's safe to use.

The bootstrap 4 class text-center is also a very good solution, however it needs a parent wrapper element. The benefit of using auto margin is that it can be done directly on the button element itself.

Here is what I ended up doing to work around the error.

First, I set up the database recovery model as SIMPLE. More information here.

Then, by deleting some old files I was able to make 5GB of free space which gave the log file more space to grow.

I reran the DELETE statement sucessfully without any warning.

I thought that by running the DELETE statement the database would inmediately become smaller thus freeing space in my hard drive. But that was not true. The space freed after a DELETE statement is not returned to the operating system inmediatedly unless you run the following command:

DBCC SHRINKDATABASE (MyDb, 0);
GO

More information about that command here.

Use group_concat() function of mysql.

SELECT GROUP_CONCAT(id) FROM table_level where parent_id=4 GROUP BY parent_id;

It'll give you concatenated string like :

5,6,9,10,12,14,15,17,18,779 

Demi Magus answer worked for me until Rails 5.

On Apache2/Passenger/Ruby (2.4)/Rails (5.1.6), I had to put

export SECRET_KEY_BASE=GENERATED_CODE

from Demi Magus answer in /etc/apache2/envvars, cause /etc/profile seems to be ignored.

Source: https://www.phusionpassenger.com/library/indepth/environment_variables.html#apache

<script> 
    var url= "http://www.google.com"; 
    window.location = url; 
</script> 

The "pre" tag defines preformatted text. It preserves both spaces and line breaks.

<!DOCTYPE html>   
 <html>
        <body>
            <pre>This paragraph will be      pre-formatted. 
I hope this helps! 
All spaces will                    be shown as it is in the original file.
            </pre>
        </body>
 </html>

I finally found an ugly workaround to refresh all rows.

void refreshTable() {
    final List<Item> items = tableView.getItems();
    if( items == null || items.size() == 0) return;

    final Item item = tableView.getItems().get(0);
    items.remove(0);
    Platform.runLater(new Runnable(){
        @Override
        public void run() {
            items.add(0, item);
        }
    });
 }

Java uses pass-by-value. It is not possible to swap two primitives or objects using a method.

Although it is possible to swap two elements in an integer array.

Seems like the accepted answer does not work anymore. I found the correct method from another post: https://stackoverflow.com/a/46811403/6368026

Now you should use:

http://www.youtube.com/embed/videoseries?list=USERID And the USERID is your youtube user id with 'UU' appended.

For example, if your user id is TlQ5niAIDsLdEHpQKQsupg then you should put UUTlQ5niAIDsLdEHpQKQsupg. If you only have the channel id (which you can find in your channel URL) then just replace the first two characters (UC) with UU.

So in the end you would have an URL like this:

http://www.youtube.com/embed/videoseries?list=UUTlQ5niAIDsLdEHpQKQsupg

I don't know much about the low level details; but, given that in python 2.6 the API offers the ability to wait for threads and terminate processes, what about running the process in a separate thread?

import subprocess, threading

class Command(object):
    def __init__(self, cmd):
        self.cmd = cmd
        self.process = None

    def run(self, timeout):
        def target():
            print 'Thread started'
            self.process = subprocess.Popen(self.cmd, shell=True)
            self.process.communicate()
            print 'Thread finished'

        thread = threading.Thread(target=target)
        thread.start()

        thread.join(timeout)
        if thread.is_alive():
            print 'Terminating process'
            self.process.terminate()
            thread.join()
        print self.process.returncode

command = Command("echo 'Process started'; sleep 2; echo 'Process finished'")
command.run(timeout=3)
command.run(timeout=1)

The output of this snippet in my machine is:

Thread started
Process started
Process finished
Thread finished
0
Thread started
Process started
Terminating process
Thread finished
-15

where it can be seen that, in the first execution, the process finished correctly (return code 0), while the in the second one the process was terminated (return code -15).

I haven't tested in windows; but, aside from updating the example command, I think it should work since I haven't found in the documentation anything that says that thread.join or process.terminate is not supported.

filter_by is used for simple queries on the column names using regular kwargs, like

db.users.filter_by(name='Joe')

The same can be accomplished with filter, not using kwargs, but instead using the '==' equality operator, which has been overloaded on the db.users.name object:

db.users.filter(db.users.name=='Joe')

You can also write more powerful queries using filter, such as expressions like:

db.users.filter(or_(db.users.name=='Ryan', db.users.country=='England'))

For checking type conversions in version 3, you can go to their github and check into the different liquibase types and check the method toDatabaseDataType. For example, for Boolean, you can check here:

https://github.com/liquibase/liquibase/blob/master/liquibase-core/src/main/java/liquibase/datatype/core/BooleanType.java

For version 2.0.x, the conversion seems to be into database specific classes. For example, for Mysql:

https://github.com/liquibase/liquibase/blob/2_0_x/liquibase-core/src/main/java/liquibase/database/typeconversion/core/MySQLTypeConverter.java

You can check your all defined function by

$arr = get_defined_functions();
print_r($arr);

this will give you array of all functions in if your function exist in it you can use it like:

 {{ user.myfunction({{parameter}}) }}

If you use Robert Harder's Base64 utility, then you can do:

InputStream is = new Base64.InputStream(cph);

Or with sun's JRE, you can do:

InputStream is = new
com.sun.xml.internal.messaging.saaj.packaging.mime.util.BASE64DecoderStream(cph)

However don't rely on that class continuing to be a part of the JRE, or even continuing to do what it seems to do today. Sun say not to use it.

There are other Stack Overflow questions about Base64 decoding, such as this one.

unique_ptr doesn't have the traditional copy constructor. Instead it has a "move constructor" that uses rvalue references:

unique_ptr::unique_ptr(unique_ptr && src);

An rvalue reference (the double ampersand) will only bind to an rvalue. That's why you get an error when you try to pass an lvalue unique_ptr to a function. On the other hand, a value that is returned from a function is treated as an rvalue, so the move constructor is called automatically.

By the way, this will work correctly:

bar(unique_ptr<int>(new int(44));

The temporary unique_ptr here is an rvalue.

Peg the pattern to find "\\.dbf" at the end of the string using the $ character:

list.files(pattern = "\\.dbf$")

This is the best solution I found so far.

in blade

@if($mentors->count() == 0)
    <td colspan="5" class="text-center">
        Nothing Found
    </td>
@endif

in controller

if ($mentors->count() == 0) {
    return "Nothing Found";
}

<?php
  $field = 'display_name';
  the_author_meta($field);
?>

Valid values for the $field parameter include:

• admin_color
• aim
• comment_shortcuts
• description
• display_name
• first_name
• ID
• jabber
• last_name
• nickname
• plugins_last_view
• plugins_per_page
• rich_editing
• syntax_highlighting
• user_activation_key
• user_description
• user_email
• user_firstname
• user_lastname
• user_level
• user_login
• user_nicename
• user_pass
• user_registered
• user_status
• user_url
• yim

I suggest to look at Dan Abramov (one of the React core maintainers) answer here:

I think you're making it more complicated than it needs to be.

function Example() {
  const [data, dataSet] = useState<any>(null)

  useEffect(() => {
    async function fetchMyAPI() {
      let response = await fetch('api/data')
      response = await response.json()
      dataSet(response)
    }

    fetchMyAPI()
  }, [])

  return <div>{JSON.stringify(data)}</div>
}

Longer term we'll discourage this pattern because it encourages race conditions. Such as — anything could happen between your call starts and ends, and you could have gotten new props. Instead, we'll recommend Suspense for data fetching which will look more like

const response = MyAPIResource.read();

and no effects. But in the meantime you can move the async stuff to a separate function and call it.

You can read more about experimental suspense here.

If you want to use functions outside with eslint.

 function OutsideUsageExample() {
  const [data, dataSet] = useState<any>(null)

  const fetchMyAPI = useCallback(async () => {
    let response = await fetch('api/data')
    response = await response.json()
    dataSet(response)
  }, [])

  useEffect(() => {
    fetchMyAPI()
  }, [fetchMyAPI])

  return (
    <div>
      <div>data: {JSON.stringify(data)}</div>
      <div>
        <button onClick={fetchMyAPI}>manual fetch</button>
      </div>
    </div>
  )
}

If you will use useCallback, look at example of how it works useCallback. Sandbox.

import React, { useState, useEffect, useCallback } from "react";

export default function App() {
  const [counter, setCounter] = useState(1);

  // if counter is changed, than fn will be updated with new counter value
  const fn = useCallback(() => {
    setCounter(counter + 1);
  }, [counter]);

  // if counter is changed, than fn will not be updated and counter will be always 1 inside fn
  /*const fnBad = useCallback(() => {
      setCounter(counter + 1);
    }, []);*/

  // if fn or counter is changed, than useEffect will rerun
  useEffect(() => {
    if (!(counter % 2)) return; // this will stop the loop if counter is not even

    fn();
  }, [fn, counter]);

  // this will be infinite loop because fn is always changing with new counter value
  /*useEffect(() => {
    fn();
  }, [fn]);*/

  return (
    <div>
      <div>Counter is {counter}</div>
      <button onClick={fn}>add +1 count</button>
    </div>
  );
}

Wanted to give my contribution, as my regex cover all cases from OP and correctly group all relevant data on the group method (you don't need to post process the string to get each part of the uuid, this regex already get it for you)

([\d\w]{8})-?([\d\w]{4})-?([\d\w]{4})-?([\d\w]{4})-?([\d\w]{12})|[{0x]*([\d\w]{8})[0x, ]{4}([\d\w]{4})[0x, ]{4}([\d\w]{4})[0x, {]{5}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})[0x, ]{4}([\d\w]{2})

1. Highlight the range in question.
2. On the Home tab, in the Styles Group, Click "Conditional Formatting".
3. Click "Highlight cell rules"

For the first rule,

Click "greater than", then in the value option box, click on the cell criteria you want it to be less than, than use the format drop-down to select your color.

For the second,

Click "less than", then in the value option box, type "=.9*" and then click the cell criteria, then use the formatting just like step 1.

For the third,

Same as the second, except your formula is =".8*" rather than .9.

You have to create the .ssh folder yourself for saving ssh keys.

By the way, I used this path style: C:/Users/you/.ssh/id_rsa

This question is old but I wanted to add an alternative to the accepted answer which didn't exist at the time.

Image Mapster is a jQuery plugin that I wrote to solve some of the shortcomings of Map Hilight (and it was initially an extension of that plugin, though it's since been almost completely rewritten). Initially, this was just the ability to maintain selection state for areas, fix browser compatibility problems. Since its initial release a few months ago, though, I have added a lot of features including the ability to use an alternate image as the source for the highlights.

It also has the ability to identify areas as "masks," meaning you can create areas with "holes", and additionally create complex groupings of areas. For example, area A could cause another area B to be highlighted, but area B itself would not respond to mouse events.

There are a few examples on the web site that show most of the features. The github repository also has more examples and complete documentation.

Many of the answers seem to me to be ignoring the stated requirements:

• The result should be a byte array
• It should be as efficient as possible

These two together rule out a LINQ sequence of bytes - anything with yield is going to make it impossible to get the final size without iterating through the whole sequence.

If those aren't the real requirements of course, LINQ could be a perfectly good solution (or the IList<T> implementation). However, I'll assume that Superdumbell knows what he wants.

(EDIT: I've just had another thought. There's a big semantic difference between making a copy of the arrays and reading them lazily. Consider what happens if you change the data in one of the "source" arrays after calling the Combine (or whatever) method but before using the result - with lazy evaluation, that change will be visible. With an immediate copy, it won't. Different situations will call for different behaviour - just something to be aware of.)

Here are my proposed methods - which are very similar to those contained in some of the other answers, certainly :)

public static byte[] Combine(byte[] first, byte[] second)
{
    byte[] ret = new byte[first.Length + second.Length];
    Buffer.BlockCopy(first, 0, ret, 0, first.Length);
    Buffer.BlockCopy(second, 0, ret, first.Length, second.Length);
    return ret;
}

public static byte[] Combine(byte[] first, byte[] second, byte[] third)
{
    byte[] ret = new byte[first.Length + second.Length + third.Length];
    Buffer.BlockCopy(first, 0, ret, 0, first.Length);
    Buffer.BlockCopy(second, 0, ret, first.Length, second.Length);
    Buffer.BlockCopy(third, 0, ret, first.Length + second.Length,
                     third.Length);
    return ret;
}

public static byte[] Combine(params byte[][] arrays)
{
    byte[] ret = new byte[arrays.Sum(x => x.Length)];
    int offset = 0;
    foreach (byte[] data in arrays)
    {
        Buffer.BlockCopy(data, 0, ret, offset, data.Length);
        offset += data.Length;
    }
    return ret;
}

Of course the "params" version requires creating an array of the byte arrays first, which introduces extra inefficiency.

Your solution requires some ajax method to pass the html to a back-end server that has a html to pdf facility and then returning the pdf output generated back to the browser.

First setting up the client side code, we will setup the jquery code as

   var options = {
            "url": "/pdf/generate/convert_to_pdf.php",
            "data": "data=" + $("#content").html(),
            "type": "post",
        }
   $.ajax(options)

Then intercept the data from the html2pdf generation script (somewhere from the internet).
convert_to_pdf.php (given as url in JQUERY code) looks like this -

<?php
    $html = $_POST['data'];
    $pdf = html2pdf($html);
    
    header("Content-Type: application/pdf"); //check this is the proper header for pdf
    header("Content-Disposition: attachment; filename='some.pdf';");
    echo $pdf;
?>

The legend titles can be labeled by specific aesthetic.

This can be achieved using the guides() or labs() functions from ggplot2 (more here and here). It allows you to add guide/legend properties using the aesthetic mapping.

Here's an example using the mtcars data set and labs():

ggplot(mtcars, aes(x=mpg, y=disp, size=hp, col=as.factor(cyl), shape=as.factor(gear))) +
  geom_point() +
  labs(x="miles per gallon", y="displacement", size="horsepower", 
       col="# of cylinders", shape="# of gears")

Answering the OP's question using guides():

# transforming the data from wide to long
require(reshape2)
dfm <- melt(df, id="TY")

# creating a scatterplot
ggplot(data = dfm, aes(x=TY, y=value, color=variable)) + 
  geom_point(size=5) +
  labs(title="Temperatures\n", x="TY [°C]", y="Txxx") +
  scale_color_manual(labels = c("T999", "T888"), values = c("blue", "red")) +
  theme_bw() +
  guides(color=guide_legend("my title"))  # add guide properties by aesthetic

You can use PATINDEX to find the first index of the pattern (string's) occurrence. Then use STUFF to stuff another string into the pattern(string) matched.

Loop through each row. Replace each illegal characters with what you want. In your case replace non numeric with blank. The inner loop is if you have more than one illegal character in a current cell that of the loop.

DECLARE @counter int

SET @counter = 0

WHILE(@counter < (SELECT MAX(ID_COLUMN) FROM Table))
BEGIN  

    WHILE 1 = 1
    BEGIN
        DECLARE @RetVal varchar(50)

        SET @RetVal =  (SELECT Column = STUFF(Column, PATINDEX('%[^0-9.]%', Column),1, '')
        FROM Table
        WHERE ID_COLUMN = @counter)

        IF(@RetVal IS NOT NULL)       
          UPDATE Table SET
          Column = @RetVal
          WHERE ID_COLUMN = @counter
        ELSE
            break
    END

    SET @counter = @counter + 1
END

Caution: This is slow though! Having a varchar column may impact. So using LTRIM RTRIM may help a bit. Regardless, it is slow.

Credit goes to this StackOverFlow answer.

EDIT Credit also goes to @srutzky

Edit (by @Tmdean) Instead of doing one row at a time, this answer can be adapted to a more set-based solution. It still iterates the max of the number of non-numeric characters in a single row, so it's not ideal, but I think it should be acceptable in most situations.

WHILE 1 = 1 BEGIN
    WITH q AS
        (SELECT ID_Column, PATINDEX('%[^0-9.]%', Column) AS n
        FROM Table)
    UPDATE Table
    SET Column = STUFF(Column, q.n, 1, '')
    FROM q
    WHERE Table.ID_Column = q.ID_Column AND q.n != 0;

    IF @@ROWCOUNT = 0 BREAK;
END;

You can also improve efficiency quite a lot if you maintain a bit column in the table that indicates whether the field has been scrubbed yet. (NULL represents "Unknown" in my example and should be the column default.)

DECLARE @done bit = 0;
WHILE @done = 0 BEGIN
    WITH q AS
        (SELECT ID_Column, PATINDEX('%[^0-9.]%', Column) AS n
        FROM Table
        WHERE COALESCE(Scrubbed_Column, 0) = 0)
    UPDATE Table
    SET Column = STUFF(Column, q.n, 1, ''),
        Scrubbed_Column = 0
    FROM q
    WHERE Table.ID_Column = q.ID_Column AND q.n != 0;

    IF @@ROWCOUNT = 0 SET @done = 1;

    -- if Scrubbed_Column is still NULL, then the PATINDEX
    -- must have given 0
    UPDATE table
    SET Scrubbed_Column = CASE
        WHEN Scrubbed_Column IS NULL THEN 1
        ELSE NULLIF(Scrubbed_Column, 0)
    END;
END;

If you don't want to change your schema, this is easy to adapt to store intermediate results in a table valued variable which gets applied to the actual table at the end.

Try this.

string path = @"E:\AppServ\Example.txt";
if (!File.Exists(path))
{
    using (var txtFile = File.AppendText(path))
    {
        txtFile.WriteLine("The very first line!");
    }
}
else if (File.Exists(path))
{     
    using (var txtFile = File.AppendText(path))
    {
        txtFile.WriteLine("The next line!");
    }
}

This issue has to do with granting the necessary authorization to the user account the application runs on. To read a similar situation and a detailed response for the correct solution, as documented by Microsoft, feel free to visit this post: http://rambletech.wordpress.com/2011/10/17/requested-registry-access-is-not-allowed/

The OP didn't actually need to pivot without agregation but for those of you coming here to know how see:

sql parameterised cte query

The answer to that question involves a situation where pivot without aggregation is needed so an example of doing it is part of the solution.

I created a simple extension method that does not need a check on Enum types:

public static bool HasAnyFlag(this Enum value, Enum flags)
{
    return
        value != null && ((Convert.ToInt32(value) & Convert.ToInt32(flags)) != 0);
}

It also works on nullable enums. The standard HasFlag method does not, so I created an extension to cover that too.

public static bool HasFlag(this Enum value, Enum flags)
{
    int f = Convert.ToInt32(flags);

    return
        value != null && ((Convert.ToInt32(value) & f) == f);
}

A simple test:

[Flags]
enum Option
{
    None = 0x00,
    One = 0x01,
    Two = 0x02,
    Three = One | Two,
    Four = 0x04
}

[TestMethod]
public void HasAnyFlag()
{
    Option o1 = Option.One;
    Assert.AreEqual(true, o1.HasAnyFlag(Option.Three));
    Assert.AreEqual(false, o1.HasFlag(Option.Three));

    o1 |= Option.Two;
    Assert.AreEqual(true, o1.HasAnyFlag(Option.Three));
    Assert.AreEqual(true, o1.HasFlag(Option.Three));
}

[TestMethod]
public void HasAnyFlag_NullableEnum()
{
    Option? o1 = Option.One;
    Assert.AreEqual(true, o1.HasAnyFlag(Option.Three));
    Assert.AreEqual(false, o1.HasFlag(Option.Three));

    o1 |= Option.Two;
    Assert.AreEqual(true, o1.HasAnyFlag(Option.Three));
    Assert.AreEqual(true, o1.HasFlag(Option.Three));
}

Enjoy!

Use this method and your listview become scrollable inside scrollview:-

   ListView lstNewsOffer.setAdapter(new ViewOfferAdapter(
                            ViewNewsDetail.this, viewOfferList));
                    getListViewSize(lstNewsOffer);

void getListViewSize(ListView myListView) {
    ListAdapter myListAdapter = myListView.getAdapter();
    if (myListAdapter == null) {
        // do nothing return null
        return;
    }
    // set listAdapter in loop for getting final size
    int totalHeight = 0;
    for (int size = 0; size < myListAdapter.getCount(); size++) {
        View listItem = myListAdapter.getView(size, null, myListView);
        listItem.measure(0, 0);
        totalHeight += listItem.getMeasuredHeight();
    }
    // setting listview item in adapter
    ViewGroup.LayoutParams params = myListView.getLayoutParams();
    params.height = totalHeight
            + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));
    myListView.setLayoutParams(params);
    // print height of adapter on log
    Log.i("height of listItem:", String.valueOf(totalHeight));
}

Following recursive function I have written, if it helps anyone. It will copy all the files inside sourcedirectory to destinationDirectory.

example:

rfunction("D:/MyDirectory", "D:/MyDirectoryNew", "D:/MyDirectory");

public static void rfunction(String sourcePath, String destinationPath, String currentPath) {
    File file = new File(currentPath);
    FileInputStream fi = null;
    FileOutputStream fo = null;

    if (file.isDirectory()) {
        String[] fileFolderNamesArray = file.list();
        File folderDes = new File(destinationPath);
        if (!folderDes.exists()) {
            folderDes.mkdirs();
        }

        for (String fileFolderName : fileFolderNamesArray) {
            rfunction(sourcePath, destinationPath + "/" + fileFolderName, currentPath + "/" + fileFolderName);
        }
    } else {
        try {
            File destinationFile = new File(destinationPath);

            fi = new FileInputStream(file);
            fo = new FileOutputStream(destinationPath);
            byte[] buffer = new byte[1024];
            int ind = 0;
            while ((ind = fi.read(buffer))>0) {
                fo.write(buffer, 0, ind);
            }
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        finally {
            if (null != fi) {
                try {
                    fi.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
            if (null != fo) {
                try {
                    fo.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
            }
        }
    }
}

function hex2rgb(hex) {
  return ['0x' + hex[1] + hex[2] | 0, '0x' + hex[3] + hex[4] | 0, '0x' + hex[5] + hex[6] | 0];
}

drop returns a new array so that is why it choked in the og post; I had a similar requirement to rename some column headers and deleted some rows due to an ill formed csv file converted to Dataframe, so after reading this post I used:

newList = pd.DataFrame(newList)
newList.columns = ['Area', 'Price']
print(newList)
# newList = newList.drop(0)
# newList = newList.drop(len(newList))
newList = newList[1:-1]
print(newList)

and it worked great, as you can see with the two commented out lines above I tried the drop.() method and it work but not as kool and readable as using [n:-n], hope that helps someone, thanks.

Easy way for this problem

WITH    q AS
        (

You can declare a dictionary inside a dictionary by nesting the {} containers:

d = {'dict1': {'foo': 1, 'bar': 2}, 'dict2': {'baz': 3, 'quux': 4}}

And then you can access the elements using the [] syntax:

print d['dict1']           # {'foo': 1, 'bar': 2}
print d['dict1']['foo']    # 1
print d['dict2']['quux']   # 4

Given the above, if you want to add another dictionary to the dictionary, it can be done like so:

d['dict3'] = {'spam': 5, 'ham': 6}

or if you prefer to add items to the internal dictionary one by one:

d['dict4'] = {}
d['dict4']['king'] = 7
d['dict4']['queen'] = 8

When your file is created. Instead of creating a file with content is empty. Replace with:

json.dump({}, file)

page-break-inside: avoid; gave me trouble using wkhtmltopdf.

To avoid breaks in the text add display: table; to the CSS of the text-containing div.

I hope this works for you too. Thanks JohnS.

I was able to use @rahularyansharma's answer above in my own project, with one minor modification. I needed to get the value of particular cells on the row on which the user clicks a LinkButton. The second line can be modified to get the value of as many cells as you wish.

Here is my solution:

GridViewRow gvr = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
string typecore = gvr.Cells[3].Text.ToString().Trim();

You can pass boolean by coercing it, put !! before the variable.

let isRequired = '' || null || undefined
<input :required="!!isRequired"> // it will coerce value to respective boolean 

But I would like to pull your attention for the following case where the receiving component has defined type for props. In that case, if isRequired has defined type to be string then passing boolean make it type check fails and you will get Vue warning. To fix that you may want to avoid passing that prop, so just put undefined fallback and the prop will not sent to component

let isValue = false
<any-component
  :my-prop="isValue ? 'Hey I am when the value exist' : undefined"
/>

Explanation

I have been through the same problem, and tried above solutions !! Yes, I don't see the prop but that actually does not fulfils what required here.

My problem -

let isValid = false
<any-component
  :my-prop="isValue ? 'Hey I am when the value exist': false"
/>

In the above case, what I expected is not having my-prop get passed to the child component - <any-conponent/> I don't see the prop in DOM but In my <any-component/> component, an error pops out of prop type check failure. As in the child component, I am expecting my-prop to be a String but it is boolean.

myProp : {
 type: String,
 required: false,
 default: ''
}

Which means that child component did receive the prop even if it is false. Tweak here is to let the child component to take the default-value and also skip the check. Passed undefined works though!

<any-component
  :my-prop="isValue ? 'Hey I am when the value exist' : undefined"
/>
 

This works and my child prop is having the default value.

In 2020, iOS13, xCode 11.3. What is working for Objective-C is:

It's working for me, i hope the same to you! :D

This sometime works, sometime no.

I have installed 1 Eclipse - works.

Installed second - doesn't work.

Unless google serves this image with the correct Access-Control-Allow-Origin header, then you wont be able to use their image in canvas. This is due to not having CORS approval. You can read more about this here, but it essentially means:

Although you can use images without CORS approval in your canvas, doing so taints the canvas. Once a canvas has been tainted, you can no longer pull data back out of the canvas. For example, you can no longer use the canvas toBlob(), toDataURL(), or getImageData() methods; doing so will throw a security error.

This protects users from having private data exposed by using images to pull information from remote web sites without permission.

I suggest just passing the URL to your server-side language and using curl to download the image. Be careful to sanitise this though!

EDIT:

As this answer is still the accepted answer, you should check out @shadyshrif's answer, which is to use:

var img = new Image();
img.setAttribute('crossOrigin', 'anonymous');
img.src = url;

This will only work if you have the correct permissions, but will at least allow you to do what you want.

In some devices void onConfigurationChanged() may crash. User will use this code to get current screen orientation.

public int getScreenOrientation()
{
    Display getOrient = getActivity().getWindowManager().getDefaultDisplay();
    int orientation = Configuration.ORIENTATION_UNDEFINED;
    if(getOrient.getWidth()==getOrient.getHeight()){
        orientation = Configuration.ORIENTATION_SQUARE;
    } else{ 
        if(getOrient.getWidth() < getOrient.getHeight()){
            orientation = Configuration.ORIENTATION_PORTRAIT;
        }else { 
             orientation = Configuration.ORIENTATION_LANDSCAPE;
        }
    }
    return orientation;
}

And use

if (orientation==1)        // 1 for Configuration.ORIENTATION_PORTRAIT
{                          // 2 for Configuration.ORIENTATION_LANDSCAPE
   //your code             // 0 for Configuration.ORIENTATION_SQUARE
}

EDIT:

It seems that it's no longer necessary to have write access to a public repo to use an SSH URL, rendering my original explanation invalid.

ORIGINAL:

Apparently the main reason for favoring HTTPS URLs is that SSH URL's won't work with a public repo if you don't have write access to that repo.

The use of SSH URLs is encouraged for deployment to production servers, however - presumably the context here is services like Heroku.

You're not suppose to test private methods. Only non-private methods needs to be tested as these should call the private methods anyway. If you "want" to test private methods, it may indicate that you need to rethink your design:

Am I using proper dependency injection? Do I possibly needs to move the private methods into a separate class and rather test that? Must these methods be private? ...can't they be default or protected rather?

In the above instance, the two methods that are called "randomly" may actually need to be placed in a class of their own, tested and then injected into the class above.

As a setter, how about:

// setter
public void beCurrent(boolean X) {
    this.isCurrent = X;
}

or

// setter
public void makeCurrent(boolean X) {
    this.isCurrent = X;
}

I'm not sure if these naming make sense to native English speakers.

I want to add a few details on top of this very excellent post by Radim.

I took this solution and worked on it for a bit and quickly ran into some limitations. I'll just outline those and then give the solution to that as well.

• First of all I was unable to render dynamic-detail inside a dynamic-detail (basically nest dynamic UIs inside each other).
• The next issue was that I wanted to render a dynamic-detail inside one of the parts that was made available in the solution. That was not possible with the initial solution either.
• Lastly it was not possible to use template URLs on the dynamic parts like string-editor.

I made another question based on this post, on how to achieve these limitations, which can be found here:

recursive dynamic template compilation in angular2

I’ll just outline the answers to these limitations, should you run into the same issue as I, as that make the solution quite more flexible. It would be awesome to have the initial plunker updated with that as well.

To enable nesting dynamic-detail inside each other, You'll need to add DynamicModule.forRoot() in the import statement in the type.builder.ts

protected createComponentModule (componentType: any) {
    @NgModule({
    imports: [
        PartsModule, 
        DynamicModule.forRoot() //this line here
    ],
    declarations: [
        componentType
    ],
    })
    class RuntimeComponentModule
    {
    }
    // a module for just this Type
    return RuntimeComponentModule;
}

Besides that it was not possible to use <dynamic-detail> inside one of the parts being string-editor or text-editor.

To enable that you'll need to change parts.module.ts and dynamic.module.ts

Inside parts.module.ts You'll need to add DynamicDetail in the DYNAMIC_DIRECTIVES

export const DYNAMIC_DIRECTIVES = [
   forwardRef(() => StringEditor),
   forwardRef(() => TextEditor),
   DynamicDetail
];

Also in the dynamic.module.ts you'd have to remove the dynamicDetail as they are now part of the parts

@NgModule({
   imports:      [ PartsModule ],
   exports:      [ PartsModule],
})

A working modified plunker can be found here: http://plnkr.co/edit/UYnQHF?p=preview (I didn’t solve this issue, I’m just the messenger :-D)

Finally it was not possible to use templateurls in the parts created on the dynamic components. A solution (or workaround. I’m not sure whether it’s an angular bug or wrong use of the framework) was to create a compiler in the constructor instead of injecting it.

    private _compiler;

    constructor(protected compiler: RuntimeCompiler) {
        const compilerFactory : CompilerFactory =
        platformBrowserDynamic().injector.get(CompilerFactory);
        this._compiler = compilerFactory.createCompiler([]);
    }

Then use the _compiler to compile, then templateUrls are enabled as well.

return new Promise((resolve) => {
        this._compiler
            .compileModuleAndAllComponentsAsync(module)
            .then((moduleWithFactories) =>
            {
                let _ = window["_"];
                factory = _.find(moduleWithFactories.componentFactories, { componentType: type });

                this._cacheOfFactories[template] = factory;

                resolve(factory);
            });
    });

Hope this helps someone else!

This can be done using HTML5, but will only work in browsers that support it. Here's an example.

Bear in mind you'll need an alternative method for browsers that don't support this. I've had a lot of success with this plugin, which takes a lot of the work out of your hands.

This type of data is efficiently pulled from a Trie-like data structure. It also allows for fast sorting. The memory efficiency might not be that great though.

A traditional trie stores each letter of a word as a node in the tree. But in your case your "alphabet" is different. You are storing strings instead of characters.

it might look something like this:

root:                Root
                     /|\
                    / | \
                   /  |  \     
fruit:       Banana Apple Strawberry
              / |      |     \
             /  |      |      \
color:     Blue Yellow Green  Blue
            /   |       |       \
           /    |       |        \
end:      24   100      12        0

see this link: trie in python

Something like this (not tested, but should work)

Pass this as parameter in Html:

<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>

And alert the value of the parameter passed into the search function:

function search(e){
  alert(e.value);
}

From the Javadoc for Date.getHours

As of JDK version 1.1, replaced by Calendar.get(Calendar.HOUR_OF_DAY)

So use

Calendar rightNow = Calendar.getInstance();
int hour = rightNow.get(Calendar.HOUR_OF_DAY);

and the equivalent for getMinutes.

using just the shell,

while read -r col1 col2
do
  echo $col2 $col1
done <"file"

Old question, but thought I'd add this to help out,

#if DOTNET35

#endif

There is a CSS unit called viewport height / viewport width.

Example

.mainbody{height: 100vh;} similarly html,body{width: 100vw;}

or 90vh = 90% of the viewport height.

Upon first appearance, the word "merg" leads one to think you need to use .extend, which is the proper jQuery way to "merge" JSON objects. However, $.extend(true, {}, json1, json2); will cause all values sharing the same key name to be overridden by the latest supplied in the params. As review of your question shows, this is undesired.

What you seek is a simple javascript function known as .concat. Which would work like:

var finalObj = json1.concat(json2);

While this is not a native jQuery function, you could easily add it to the jQuery library for simple future use as follows:

;(function($) {
    if (!$.concat) {
        $.extend({
            concat: function() {
                return Array.prototype.concat.apply([], arguments);
            }
        });
    }
})(jQuery);

And then recall it as desired like:

var finalObj = $.concat(json1, json2);

You can also use it for multiple array objects of this type with a like:

var finalObj = $.concat(json1, json2, json3, json4, json5, ....);

And if you really want it jQuery style and very short and sweet (aka minified)

;(function(a){a.concat||a.extend({concat:function(){return Array.prototype.concat.apply([],arguments);}})})(jQuery);

;(function($){$.concat||$.extend({concat:function(){return Array.prototype.concat.apply([],arguments);}})})(jQuery);_x000D_

If you are using md-select and ng-repeat ing md-option from angular material then you can add ng-model-options="{trackBy: '$value.id'}" to the md-select tag ash shown in this pen

I had the exact same message as displayed in the question. I have tried many suggestions with little luck. I was about to install WAMP (I'm on Windows) and was about to uninstall MySql 8.0 first, when I noticed a program included in the installation: 'MySQL Installer - Community' so I tried that. With this installer I set up a new connection, added password to root, added another user with password, set my choice of locations for all logs and ran the install. The result was that it now totally works.

Some of the files individually listed by Simon would also be found with something like the following command, but with some additional assurance about thoroughness, and without the recklessness of using rm -rf with wildcards:

find ~ \
  -path ~/Library/Caches/Metadata/Safari -prune -o \
  -iname \*android\*studio\* -print -prune

Also don't forget about the SDK, which is now separate from the application, and ~/.gradle/ (see vijay's answer).

    thresholds.Add(60, "{0} seconds ago");
    thresholds.Add(minute * 2, "a minute ago");
    thresholds.Add(45 * minute, "{0} minutes ago");
    thresholds.Add(120 * minute, "an hour ago");

            return string.Format(thresholds[threshold], (t.Days > 365 ? t.Days / 365 : (t.Days > 0 ? t.Days : (t.Hours > 0 ? t.Hours : (t.Minutes > 0 ? t.Minutes : (t.Seconds > 0 ? t.Seconds : 0))))).ToString());

I prefer this version for its conciseness, and ability to add in new tick points. This could be encapsulated with a Latest() extension to Timespan instead of that long 1 liner, but for the sake of brevity in posting, this will do. This fixes the an hour ago, 1 hours ago, by providing an hour until 2 hours have elapsed

I had referenced this article and many others and did not find a clear cut concise response to help. I am offering my discovery, arrived at with some references from this thread, in the following:

Spring-Boot version: 1.3.5.RELEASE

Spring-Core version: 4.2.6.RELEASE

Dependency Management: Brixton.SR1

The following is the pertinent yaml excerpt:

tools:
  toolList:
    - 
      name: jira
      matchUrl: http://someJiraUrl
    - 
      name: bamboo
      matchUrl: http://someBambooUrl

I created a Tools.class:

@Component
@ConfigurationProperties(prefix = "tools")
public class Tools{
    private List<Tool> toolList = new ArrayList<>();
    public Tools(){
      //empty ctor
    }

    public List<Tool> getToolList(){
        return toolList;
    }

    public void setToolList(List<Tool> tools){
       this.toolList = tools;
    }
}

I created a Tool.class:

@Component
public class Tool{
    private String name;
    private String matchUrl;

    public Tool(){
      //empty ctor
    }

    public String getName(){
        return name;
    }

    public void setName(String name){
       this.name= name;
    }
    public String getMatchUrl(){
        return matchUrl;
    }

    public void setMatchUrl(String matchUrl){
       this.matchUrl= matchUrl;
    }

    @Override
    public String toString(){
        StringBuffer sb = new StringBuffer();
        String ls = System.lineSeparator();
        sb.append(ls);
        sb.append("name:  " + name);
        sb.append(ls);
        sb.append("matchUrl:  " + matchUrl);
        sb.append(ls);
    }
}

I used this combination in another class through @Autowired

@Component
public class SomeOtherClass{

   private Logger logger = LoggerFactory.getLogger(SomeOtherClass.class);

   @Autowired
   private Tools tools;

   /* excluded non-related code */

   @PostConstruct
   private void init(){
       List<Tool>  toolList = tools.getToolList();
       if(toolList.size() > 0){
           for(Tool t: toolList){
               logger.info(t.toString());
           }
       }else{
           logger.info("*****-----     tool size is zero     -----*****");
       }  
   }

   /* excluded non-related code */

}

And in my logs the name and matching url's were logged. This was developed on another machine and thus I had to retype all of the above so please forgive me in advance if I inadvertently mistyped.

I hope this consolidation comment is helpful to many and I thank the previous contributors to this thread!

If anyone wants to get only the selected value on click to an option, he can do the follow:

$('.chosen-select').on('change', function(evt, params) {
    var selectedValue = params.selected;
    console.log(selectedValue);
});

Has anyone thought of using a PARTITION BY clause? It worked for me in this query to get a list of application services and the access.

SELECT DISTINCT T.APP_SVC_ID, 
       LISTAGG(RTRIM(T.ACCESS_MODE), ',') WITHIN GROUP(ORDER BY T.ACCESS_MODE) OVER(PARTITION BY T.APP_SVC_ID) AS ACCESS_MODE 
  FROM APP_SVC_ACCESS_CNTL T 
 GROUP BY T.ACCESS_MODE, T.APP_SVC_ID

I had to cut out my where clause for NDA, but you get the idea.

Try this, it helped me: wrap the div in tags, the problem is that it will center the content of the div also (if not coded otherwise). Hope that helps :)

Assuming the second window is defined as public partial class Window2 : Window, you can do it by:

Window2 win2 = new Window2();
win2.Show();

Use asList() method. From java Doc asList

List<String> species = Arrays.asList(speciesArr);

Ant Runtime

Simply set includeantruntime="false":

<javac includeantruntime="false" ...>...</javac>

If you have to use the javac-task multiple times you might want to consider using PreSetDef to define your own javac-task that always sets includeantruntime="false".

Additional Details

From http://www.coderanch.com/t/503097/tools/warning-includeantruntime-was-not-set:

That's caused by a misfeature introduced in Ant 1.8. Just add an attribute of that name to the javac task, set it to false, and forget it ever happened.

From http://ant.apache.org/manual/Tasks/javac.html:

Whether to include the Ant run-time libraries in the classpath; defaults to yes, unless build.sysclasspath is set. It is usually best to set this to false so the script's behavior is not sensitive to the environment in which it is run.

You'll want to change the extension of your css file from .css.scss to .css.scss.erb and do:

background-image:url(<%=asset_path "admin/logo.png"%>);

You may need to do a "hard refresh" to see changes. CMD+SHIFT+R on OSX browsers.

In production, make sure

rm -rf public/assets    
bundle exec rake assets:precompile RAILS_ENV=production

happens upon deployment.

The only thing that worked me is to export to PATH the Python version that is related to the pip3 of course :) (after a lot of struggling) just run:

which pip3

you should get something like (in Mac):

/Library/Frameworks/Python.framework/Versions/3.6/bin/pip3

Now run:

export PATH=/Library/Python/3.6/bin:$PATH

If it works for you :) just add it to your bashrc or zshrc

Using BalusC's suggestion of implementing Collection i can now hide my primefaces p:dataTable using not empty operator on my dataModel that extends javax.faces.model.ListDataModel

Code sample:

import java.io.Serializable;
import java.util.Collection;
import java.util.List;
import javax.faces.model.ListDataModel;
import org.primefaces.model.SelectableDataModel;

public class EntityDataModel extends ListDataModel<Entity> implements
        Collection<Entity>, SelectableDataModel<Entity>, Serializable {

    public EntityDataModel(List<Entity> data) { super(data); }

    @Override
    public Entity getRowData(String rowKey) {
        // In a real app, a more efficient way like a query by rowKey should be
        // implemented to deal with huge data
        List<Entity> entitys = (List<Entity>) getWrappedData();
        for (Entity entity : entitys) {
            if (Integer.toString(entity.getId()).equals(rowKey)) return entity;
        }
        return null;
    }

    @Override
    public Object getRowKey(Entity entity) {
        return entity.getId();
    }

    @Override
    public boolean isEmpty() {
        List<Entity> entity = (List<Entity>) getWrappedData();
        return (entity == null) || entity.isEmpty();
    }
    // ... other not implemented methods of Collection...
}

Generally, I don't really see a possible way to do this. I've exhausted all of the options that the earlier comments gave you, and they don't seem to work. You could try this:

        `private void button1_Click(object sender, EventArgs e)
    {
        Stream myStream = null;
        OpenFileDialog openFileDialog1 = new OpenFileDialog();
        openFileDialog1.InitialDirectory = "This PC\\Documents";
        openFileDialog1.Filter = "All Files (*.*)|*.*";
        openFileDialog1.FilterIndex = 1;
        openFileDialog1.RestoreDirectory = true;
        openFileDialog1.Title = "Open a file with code";

        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            string exeCode = string.Empty;
            using (BinaryReader br = new BinaryReader(File.OpenRead(openFileDialog1.FileName))) //Sets a new integer to the BinaryReader
            {
                br.BaseStream.Seek(0x4D, SeekOrigin.Begin); //The seek is starting from 0x4D
                exeCode = Encoding.UTF8.GetString(br.ReadBytes(1000000000)); //Reads as many bytes as it can from the beginning of the .exe file
            }
            using (BinaryReader br = new BinaryReader(File.OpenRead(openFileDialog1.FileName)))
                br.Close(); //Closes the BinaryReader. Without it, opening the file with any other command will result the error "This file is being used by another process".

            richTextBox1.Text = exeCode;
        }
    }`

• That's the code for the "Open..." button, but here's the code for the "Save..." button:

  ` private void button2_Click(object sender, EventArgs e) { SaveFileDialog save = new SaveFileDialog();

      save.Filter = "All Files (*.*)|*.*";
      save.Title = "Save Your Changes";
      save.InitialDirectory = "This PC\\Documents";
      save.FilterIndex = 1;
  
      if (save.ShowDialog() == DialogResult.OK)
      {
  
          using (BinaryWriter bw = new BinaryWriter(File.OpenWrite(save.FileName))) //Sets a new integer to the BinaryReader
          {
              bw.BaseStream.Seek(0x4D, SeekOrigin.Begin); //The seek is starting from 0x4D
              bw.Write(richTextBox1.Text);
          }
      }
  }`
  

  • That's the save button. This works fine, but only shows the '!This cannot be run in DOS-Mode!' - Otherwise, if you can fix this, I don't know what to do.

Note I think that BindingFlags.Instance and BindingFlags.Static are exclusive.

this is because deleting projects or class libraries from solution and adding projects after deleting with same name. best thing is delete solution file and add projects to it.this works for me (I did this using vsCode)

I do it like this and it's work for me, I hope this will help :)

   <div id="data">
        <form>
            <input type="file" name="userfile" id="userfile" size="20" />
            <br /><br />
            <input type="button" id="upload" value="upload" />
        </form>
    </div>
  <script>
        $(document).ready(function(){
                $('#upload').click(function(){

                    console.log('upload button clicked!')
                    var fd = new FormData();    
                    fd.append( 'userfile', $('#userfile')[0].files[0]);

                    $.ajax({
                      url: 'upload/do_upload',
                      data: fd,
                      processData: false,
                      contentType: false,
                      type: 'POST',
                      success: function(data){
                        console.log('upload success!')
                        $('#data').empty();
                        $('#data').append(data);

                      }
                    });
                });
        });
    </script>   

Agree no matches in your example.
If you mean both columns on either then need a query like this or need to re-examine the data design.

    Select TableA.Col1, TableA.Col2, TableB.Val
    FROM TableA
    INNER JOIN TableB
          ON TableA.Col1 = TableB.Col1 OR TableA.Col2 = TableB.Col2 
          OR TableA.Col2 = TableB.Col1 OR TableA.Col1 = TableB.Col2

You can use the createQuery method (direct in the controller) :

$query = $em->createQuery("SELECT o FROM AcmeCodeBundle:Orders o WHERE o.OrderMail =  :ordermail and o.Product like :searchterm")
->setParameter('searchterm', '%'.$searchterm.'%')
->setParameter('ordermail', '[email protected]');

You need to change AcmeCodeBundle to match your bundle name

Or even better - create a repository class for the entity and create a method in there - this will make it reusable

If interested in doing this without jQuery - here's a pure JS variant (from here) of the answer currently most upvoted:

var xhr = new XMLHttpRequest();
xhr.open("GET", "/img", true);
xhr.responseType = 'document';
xhr.onload = () => {
  if (xhr.status === 200) {
    var elements = xhr.response.getElementsByTagName("a");
    for (x of elements) {
      if ( x.href.match(/\.(jpe?g|png|gif)$/) ) { 
          let img = document.createElement("img");
          img.src = x.href;
          document.body.appendChild(img);
      } 
    };
  } 
  else {
    alert('Request failed. Returned status of ' + xhr.status);
  }
}
xhr.send()

For yarn users:

yarn add package_name@version_number

I have installed VMWare Workstation. So, It was causing the error.

Services.msc and stopped the 'Workstation' Services.

This has solved my problems.

Yes, the first means "match all strings that start with a letter", the second means "match all strings that contain a non-letter". The caret ("^") is used in two different ways, one to signal the start of the text, one to negate a character match inside square brackets.

Pure-PHP implementation of Rijndael exists with phpseclib available as composer package and works on PHP 7.3 (tested by me).

There's a page on the phpseclib docs, which generates sample code after you input the basic variables (cipher, mode, key size, bit size). It outputs the following for Rijndael, ECB, 256, 256:

a code with mycrypt

$decoded = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, ENCRYPT_KEY, $term, MCRYPT_MODE_ECB);

works like this with the library

$rijndael = new \phpseclib\Crypt\Rijndael(\phpseclib\Crypt\Rijndael::MODE_ECB);
$rijndael->setKey(ENCRYPT_KEY);
$rijndael->setKeyLength(256);
$rijndael->disablePadding();
$rijndael->setBlockLength(256);

$decoded = $rijndael->decrypt($term);

* $term was base64_decoded

Try this.

public function getDownload()
{
    //PDF file is stored under project/public/download/info.pdf
    $file= public_path(). "/download/info.pdf";

    $headers = array(
              'Content-Type: application/pdf',
            );

    return Response::download($file, 'filename.pdf', $headers);
}

"./download/info.pdf"will not work as you have to give full physical path.

Update 20/05/2016

Laravel 5, 5.1, 5.2 or 5.* users can use the following method instead of Response facade. However, my previous answer will work for both Laravel 4 or 5. (the $header array structure change to associative array =>- the colon after 'Content-Type' was deleted - if we don't do those changes then headers will be added in wrong way: the name of header wil be number started from 0,1,...)

$headers = [
              'Content-Type' => 'application/pdf',
           ];

return response()->download($file, 'filename.pdf', $headers);

The issue is that you're not saving the mysqli connection. Change your connect to:

$aVar = mysqli_connect('localhost','tdoylex1_dork','dorkk','tdoylex1_dork');

And then include it in your query:

$query1 = mysqli_query($aVar, "SELECT name1 FROM users
    ORDER BY RAND()
    LIMIT 1");
$aName1 = mysqli_fetch_assoc($query1);
$name1 = $aName1['name1'];

Also don't forget to enclose your connections variables as strings as I have above. This is what's causing the error but you're using the function wrong, mysqli_query returns a query object but to get the data out of this you need to use something like mysqli_fetch_assoc http://php.net/manual/en/mysqli-result.fetch-assoc.php to actually get the data out into a variable as I have above.

You can use org.apache.commons.lang.time.DateUtils to make it cleaner:

(firstDate.getTime() - secondDate.getTime()) / DateUtils.MILLIS_PER_SECOND

Object.prototype.toString.call(myVar) will return:

• "[object Object]" if myVar is an object
• "[object Array]" if myVar is an array
• etc.

use INSERT IGNORE INTO table

see http://bogdan.org.ua/2007/10/18/mysql-insert-if-not-exists-syntax.html

there's also INSERT … ON DUPLICATE KEY UPDATE syntax, you can find explanations on dev.mysql.com

Post from bogdan.org.ua according to Google's webcache:

18th October 2007

To start: as of the latest MySQL, syntax presented in the title is not possible. But there are several very easy ways to accomplish what is expected using existing functionality.

There are 3 possible solutions: using INSERT IGNORE, REPLACE, or INSERT … ON DUPLICATE KEY UPDATE.

Imagine we have a table:

CREATE TABLE `transcripts` (
`ensembl_transcript_id` varchar(20) NOT NULL,
`transcript_chrom_start` int(10) unsigned NOT NULL,
`transcript_chrom_end` int(10) unsigned NOT NULL,
PRIMARY KEY (`ensembl_transcript_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Now imagine that we have an automatic pipeline importing transcripts meta-data from Ensembl, and that due to various reasons the pipeline might be broken at any step of execution. Thus, we need to ensure two things:

1. repeated executions of the pipeline will not destroy our database

2. repeated executions will not die due to ‘duplicate primary key’ errors.

Method 1: using REPLACE

It’s very simple:

REPLACE INTO `transcripts`
SET `ensembl_transcript_id` = 'ENSORGT00000000001',
`transcript_chrom_start` = 12345,
`transcript_chrom_end` = 12678;

If the record exists, it will be overwritten; if it does not yet exist, it will be created. However, using this method isn’t efficient for our case: we do not need to overwrite existing records, it’s fine just to skip them.

Method 2: using INSERT IGNORE Also very simple:

INSERT IGNORE INTO `transcripts`
SET `ensembl_transcript_id` = 'ENSORGT00000000001',
`transcript_chrom_start` = 12345,
`transcript_chrom_end` = 12678;

Here, if the ‘ensembl_transcript_id’ is already present in the database, it will be silently skipped (ignored). (To be more precise, here’s a quote from MySQL reference manual: “If you use the IGNORE keyword, errors that occur while executing the INSERT statement are treated as warnings instead. For example, without IGNORE, a row that duplicates an existing UNIQUE index or PRIMARY KEY value in the table causes a duplicate-key error and the statement is aborted.”.) If the record doesn’t yet exist, it will be created.

This second method has several potential weaknesses, including non-abortion of the query in case any other problem occurs (see the manual). Thus it should be used if previously tested without the IGNORE keyword.

Method 3: using INSERT … ON DUPLICATE KEY UPDATE:

Third option is to use INSERT … ON DUPLICATE KEY UPDATE syntax, and in the UPDATE part just do nothing do some meaningless (empty) operation, like calculating 0+0 (Geoffray suggests doing the id=id assignment for the MySQL optimization engine to ignore this operation). Advantage of this method is that it only ignores duplicate key events, and still aborts on other errors.

As a final notice: this post was inspired by Xaprb. I’d also advise to consult his other post on writing flexible SQL queries.

For those using Magit, hit l and =m to toggle --no-merges and =pto toggle --first-parent.

Then either just hit l again to show commits from the current branch (with none of commits merged onto it) down to end of history, or, if you want the log to end where it was branched off from master, hit o and type master.. as your range:

If you just want to get the file names and not directory names then use :

dir /b /a-d > file.txt

Action method needs to return FileResult with either a stream, byte[], or virtual path of the file. You will also need to know the content-type of the file being downloaded. Here is a sample (quick/dirty) utility method. Sample video link How to download files using asp.net core

[Route("api/[controller]")]
public class DownloadController : Controller
{
    [HttpGet]
    public async Task<IActionResult> Download()
    {
        var path = @"C:\Vetrivel\winforms.png";
        var memory = new MemoryStream();
        using (var stream = new FileStream(path, FileMode.Open))
        {
            await stream.CopyToAsync(memory);
        }
        memory.Position = 0;
        var ext = Path.GetExtension(path).ToLowerInvariant();
        return File(memory, GetMimeTypes()[ext], Path.GetFileName(path));
    }

    private Dictionary<string, string> GetMimeTypes()
    {
        return new Dictionary<string, string>
        {
            {".txt", "text/plain"},
            {".pdf", "application/pdf"},
            {".doc", "application/vnd.ms-word"},
            {".docx", "application/vnd.ms-word"},
            {".png", "image/png"},
            {".jpg", "image/jpeg"},
            ...
        };
    }
}

Show Processlist fetches the information from another table. Here is how you can pull the data and look at 'INFO' column which contains the whole query :

select * from INFORMATION_SCHEMA.PROCESSLIST where db = 'somedb';

You can add any condition or ignore based on your requirement.

The output of the query is resulted as :

+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
| ID    | USER | HOST            | DB     | COMMAND | TIME | STATE     | INFO                                                     |

I ran : npm i gulp-sass@latest --save-dev

That did the magic for me

If you use any(lst) you see that lst is the iterable, which is a list of some items. If it contained [0, False, '', 0.0, [], {}, None] (which all have boolean values of False) then any(lst) would be False. If lst also contained any of the following [-1, True, "X", 0.00001] (all of which evaluate to True) then any(lst) would be True.

In the code you posted, x > 0 for x in lst, this is a different kind of iterable, called a generator expression. Before generator expressions were added to Python, you would have created a list comprehension, which looks very similar, but with surrounding []'s: [x > 0 for x in lst]. From the lst containing [-1, -2, 10, -4, 20], you would get this comprehended list: [False, False, True, False, True]. This internal value would then get passed to the any function, which would return True, since there is at least one True value.

But with generator expressions, Python no longer has to create that internal list of True(s) and False(s), the values will be generated as the any function iterates through the values generated one at a time by the generator expression. And, since any short-circuits, it will stop iterating as soon as it sees the first True value. This would be especially handy if you created lst using something like lst = range(-1,int(1e9)) (or xrange if you are using Python2.x). Even though this expression will generate over a billion entries, any only has to go as far as the third entry when it gets to 1, which evaluates True for x>0, and so any can return True.

If you had created a list comprehension, Python would first have had to create the billion-element list in memory, and then pass that to any. But by using a generator expression, you can have Python's builtin functions like any and all break out early, as soon as a True or False value is seen.

if the array looks like:

• $featured["fruit"] = "orange";
• $featured["fruit"] = "banana";
• $featured["vegetable"] = "carrot";

the $key will hold the type (fruit or vegetable) for each array value (orange, banana or carrot)

In C and languages based on the C syntax, the prefix 0x means hexadecimal (base 16).

Thus, 0x400 = 4×(16²) + 0×(16¹) + 0×(16⁰) = 4×((2⁴)²) = 2² × 2⁸ = 2¹⁰ = 1024, or one binary K.

And so 0x6400 = 0x4000 + 0x2400 = 0x19×0x400 = 25K

And you can use HTML5's autofocus attribute (works in all current browsers except IE9 and below). Only call your script if it's IE9 or earlier, or an older version of other browsers.

<input type="text" name="fname" autofocus>

I have a Samsung Galaxy Tab 2 7.0 with Android 4.1.1. Apparently it does NOT sync to ntp. I loaded an app that says my tablet is 20 seconds off of ntp, but it can't set it unless I root the device.

Your project might not have aspx files since it might be another kind of web project.

However, if it has a ClientApp folder:

1. go to the standard view of the Solution Explorer (Ctrl+Alt+L) where you can find your-project name solution (click on the folders icon at the top to be sure (saying "Solutions and Folders"))
2. right-click on the ClientApp folder itself
3. Browse with... will show up near the top (near View in Browser option), click on it and the browsers dialog shows up
4. click on your preferred browser
5. click on Set as Default
6. click on Browse to confirm (this will open the browser you just chose on that folder)

Remove

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.16</version>
</dependency> 

slf4j-log4j12 is the log4j binding for slf4j you dont need to add another log4j dependency.

Added
Provide the log4j configuration in log4j.properties and add it to your class path. There are sample configurations here

or you can change your binding to

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>
    <version>1.6.1</version>
</dependency>

if you are configuring slf4j due to some dependencies requiring it.

In windows you should use %WORKSPACE%.

You can use a Dictionary to keep track of the keys and values.

For instance...

dictOfStuff = {} ##Make a Dictionary

x = "Buffalo" ##OR it can equal the input of something, up to you.

dictOfStuff[x] = 4 ##Get the dict spot that has the same key ("name") as what X is equal to. In this case "Buffalo". and set it to 4. Or you can set it to  what ever you like

print(dictOfStuff[x]) ##print out the value of the spot in the dict that same key ("name") as the dictionary.

A dictionary is very similar to a real life dictionary. You have a word and you have a definition. You can look up the word and get the definition. So in this case, you have the word "Buffalo" and it's definition is 4. It can work with any other word and definition. Just make sure you put them into the dictionary first.

You can use the jQuery plugin PositionCalculator

That plugin has also included collision handling (flip), so the toolbar-like menu can be placed at a visible position.

$(".placeholder").on('mouseover', function() {
    var $menu = $("#menu").show();// result for hidden element would be incorrect
    var pos = $.PositionCalculator( {
        target: this,
        targetAt: "top right",
        item: $menu,
        itemAt: "top left",
        flip: "both"
    }).calculate();

    $menu.css({
        top: parseInt($menu.css('top')) + pos.moveBy.y + "px",
        left: parseInt($menu.css('left')) + pos.moveBy.x + "px"
    });
});

for that markup:

<ul class="popup" id="menu">
    <li>Menu item</li>
    <li>Menu item</li>
    <li>Menu item</li>

If you are using WebStorm and you are on Windows i would recommend you to click settings/editor/code style/general tab and select "windows(\r\n) from the dropdown menu.These steps will also apply for Rider.

Another useful thing to do with numpy.histogram is to plot the output as the x and y coordinates on a linegraph. For example:

arr = np.random.randint(1, 51, 500)
y, x = np.histogram(arr, bins=np.arange(51))
fig, ax = plt.subplots()
ax.plot(x[:-1], y)
fig.show()

This can be a useful way to visualize histograms where you would like a higher level of granularity without bars everywhere. Very useful in image histograms for identifying extreme pixel values.

Calling setOpaque(false) on the upper JPanel should work.

From your comment, it sounds like Swing painting may be broken somewhere -

First - you probably wanted to override paintComponent() rather than paint() in whatever component you have paint() overridden in.

Second - when you do override paintComponent(), you'll first want to call super.paintComponent() first to do all the default Swing painting stuff (of which honoring setOpaque() is one).

Example -

import java.awt.Color;
import java.awt.Graphics;

import javax.swing.JFrame;
import javax.swing.JPanel;


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

        JPanel p = new JPanel();
        // setting layout to null so we can make panels overlap
        p.setLayout(null);

        CirclePanel topPanel = new CirclePanel();
        // drawing should be in blue
        topPanel.setForeground(Color.blue);
        // background should be black, except it's not opaque, so 
        // background will not be drawn
        topPanel.setBackground(Color.black);
        // set opaque to false - background not drawn
        topPanel.setOpaque(false);
        topPanel.setBounds(50, 50, 100, 100);
        // add topPanel - components paint in order added, 
        // so add topPanel first
        p.add(topPanel);

        CirclePanel bottomPanel = new CirclePanel();
        // drawing in green
        bottomPanel.setForeground(Color.green);
        // background in cyan
        bottomPanel.setBackground(Color.cyan);
        // and it will show this time, because opaque is true
        bottomPanel.setOpaque(true);
        bottomPanel.setBounds(30, 30, 100, 100);
        // add bottomPanel last...
        p.add(bottomPanel);

        // frame handling code...
        JFrame f = new JFrame("Two Panels");
        f.setContentPane(p);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setSize(300, 300);
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }

    // Panel with a circle drawn on it.
    private static class CirclePanel extends JPanel {

        // This is Swing, so override paint*Component* - not paint
        protected void paintComponent(Graphics g) {
            // call super.paintComponent to get default Swing 
            // painting behavior (opaque honored, etc.)
            super.paintComponent(g);
            int x = 10;
            int y = 10;
            int width = getWidth() - 20;
            int height = getHeight() - 20;
            g.drawArc(x, y, width, height, 0, 360);
        }
    }

I installed pip3 using

python3.7 -m pip install pip

But upon using pip3 to install other dependencies, it was using python3.6.
You can check the by typing pip3 --version

Hence, I used pip3 like this (stated in one of the above answers):

python3.7 -m pip install <module>

or use it like this:

python3.7 -m pip install -r requirements.txt

I made a bash alias for later use in ~/.bashrc file as alias pip3='python3.7 -m pip'. If you use alias, don't forget to source ~/.bashrc after making the changes and saving it.

Create a custom return type that will propagate the checked exception. This is an alternative to creating a new interface that mirrors the existing functional interface with the slight modification of a "throws exception" on the functional interface's method.

Definition

CheckedValueSupplier

public static interface CheckedValueSupplier<V> {
    public V get () throws Exception;
}

CheckedValue

public class CheckedValue<V> {
    private final V v;
    private final Optional<Exception> opt;

    public Value (V v) {
        this.v = v;
    }

    public Value (Exception e) {
        this.opt = Optional.of(e);
    }

    public V get () throws Exception {
        if (opt.isPresent()) {
            throw opt.get();
        }
        return v;
    }

    public Optional<Exception> getException () {
        return opt;
    }

    public static <T> CheckedValue<T> returns (T t) {
        return new CheckedValue<T>(t);
    }

    public static <T> CheckedValue<T> rethrows (Exception e) {
        return new CheckedValue<T>(e);
    }

    public static <V> CheckedValue<V> from (CheckedValueSupplier<V> sup) {
        try {
            return CheckedValue.returns(sup.get());
        } catch (Exception e) {
            return Result.rethrows(e);
        }
    }

    public static <V> CheckedValue<V> escalates (CheckedValueSupplier<V> sup) {
        try {
            return CheckedValue.returns(sup.get());
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

}

Usage

//  Don't use this pattern with FileReader, it's meant to be an
//  example.  FileReader is a Closeable resource and as such should
//  be managed in a try-with-resources block or in another safe
//  manner that will make sure it is closed properly.

//  This will not compile as the FileReader constructor throws
//  an IOException.
    Function<String, FileReader> sToFr =
        (fn) -> new FileReader(Paths.get(fn).toFile());

// Alternative, this will compile.
    Function<String, CheckedValue<FileReader>> sToFr = (fn) -> {
        return CheckedValue.from (
            () -> new FileReader(Paths.get("/home/" + f).toFile()));
    };

// Single record usage
    // The call to get() will propagate the checked exception if it exists.
    FileReader readMe = pToFr.apply("/home/README").get();


// List of records usage
    List<String> paths = ...; //a list of paths to files
    Collection<CheckedValue<FileReader>> frs =
        paths.stream().map(pToFr).collect(Collectors.toList());

// Find out if creation of a file reader failed.
    boolean anyErrors = frs.stream()
        .filter(f -> f.getException().isPresent())
        .findAny().isPresent();

What's going on?

A single functional interface that throws a checked exception is created (CheckedValueSupplier). This will be the only functional interface which allows checked exceptions. All other functional interfaces will leverage the CheckedValueSupplier to wrap any code that throws a checked exception.

The CheckedValue class will hold the result of executing any logic that throws a checked exception. This prevents propagation of a checked exception until the point at which code attempts to access the value that an instance of CheckedValue contains.

The problems with this approach.

• We are now throwing "Exception" effectively hiding the specific type originally thrown.
• We are unaware that an exception occurred until CheckedValue#get() is called.

Consumer et al

Some functional interfaces (Consumer for example) must be handled in a different manner as they don't provide a return value.

Function in lieu of Consumer

One approach is to use a function instead of a consumer, which applies when handling streams.

    List<String> lst = Lists.newArrayList();
// won't compile
lst.stream().forEach(e -> throwyMethod(e));
// compiles
lst.stream()
    .map(e -> CheckedValueSupplier.from(
        () -> {throwyMethod(e); return e;}))
    .filter(v -> v.getException().isPresent()); //this example may not actually run due to lazy stream behavior

Escalate

Alternatively, you can always escalate to a RuntimeException. There are other answers that cover escalation of a checked exception from within a Consumer.

Don't consume.

Just avoid functional interfaces all together and use a good-ole-fashioned for loop.

Try

apt-get -d install <packages>

It is documented in man apt-get.

Just for clarification; the downloaded packages are located in the apt package cache at

/var/cache/apt/archives

As per the DOM structure you can use below code:

var x = document.getElementById('mySelect');
     var txt = "";
     var val = "";
     for (var i = 0; i < x.length; i++) {
         txt +=x[i].text + ",";
         val +=x[i].value + ",";
      }

You can post data to a url with JavaScript & Jquery something like that:

$.post("www.abc.com/details", {
    json_string: JSON.stringify({name:"John", phone number:"+410000000"})
});

If you don't want to use jQuery you can try this approach:

public setCaretPosition() {
    const editableDiv = document.getElementById('contenteditablediv');
    const lastLine = this.input.nativeElement.innerHTML.replace(/.*?(<br>)/g, '');
    const selection = window.getSelection();
    selection.collapse(editableDiv.childNodes[editableDiv.childNodes.length - 1], lastLine.length);
}

editableDiv you editable element, don't forget to set an id for it. Then you need to get your innerHTML from the element and cut all brake lines. And just set collapse with next arguments.

In php, we have two option to concatenate table columns.

First Option using Query

In query, CONCAT keyword used to concatenate two columns

SELECT CONCAT(`SUBJECT`,'_', `YEAR`) AS subject_year FROM `table_name`;

Second Option using symbol ( . )

After fetch the data from database table, assign the values to variable, then using ( . ) Symbol and concatenate the values

$subject = $row['SUBJECT'];
$year = $row['YEAR'];
$subject_year = $subject . "_" . $year;

Instead of underscore( _ ) , we will use the spaces, comma, letters,numbers..etc

Just call it using super.

public void myMethod()
{
    // B stuff
    super.myMethod();
    // B stuff
}

Since when the edit is complete the focus from the element is always lost you could simply use the onBlur hook.

<div onBlur={(e)=>{console.log(e.currentTarget.textContent)}} contentEditable suppressContentEditableWarning={true}>
     <p>Lorem ipsum dolor.</p>
</div>

You can use var_dump or print_r functions on Blade themplate via Controller functions :

class myController{

   public function showView(){
     return view('myView',["myController"=>$this]);
   }
   public function myprint($obj){
     echo "<pre>";
     print_r($obj);
     echo "</pre>";
   }
}

And use your blade themplate :

$myController->myprint($users);

Probably you are facing problem when a download request is made by the maybe_download function call in base.py file.

There is a conflict in the permissions of the temporary files and I myself couldn't work out a way to change the permissions, but was able to work around the problem.

Do the following...

• Download the four .gz files of the MNIST data set from the link ( http://yann.lecun.com/exdb/mnist/ )
• Then make a folder names MNIST_data (or your choice in your working directory/ site packages folder in the tensorflow\examples folder).
• Directly copy paste the files into the folder.
• Copy the address of the folder (it probably will be ( C:\Python\Python35\Lib\site-packages\tensorflow\examples\tutorials\mnist\MNIST_data ))
• Change the "\" to "/" as "\" is used for escape characters, to access the folder locations.
• Lastly, if you are following the tutorials, your call function would be ( mnist = input_data.read_data_sets("MNIST_data/", one_hot=True) ) ; change the "MNIST_data/" parameter to your folder location. As in my case would be ( mnist = input_data.read_data_sets("C:/Python/Python35/Lib/site-packages/tensorflow/examples/tutorials/mnist/MNIST_data", one_hot=True) )

Then it's all done. Hope it works for you.

My decimals are too big for %E so I had to improvize:

def format_decimal(x, prec=2):
    tup = x.as_tuple()
    digits = list(tup.digits[:prec + 1])
    sign = '-' if tup.sign else ''
    dec = ''.join(str(i) for i in digits[1:])
    exp = x.adjusted()
    return '{sign}{int}.{dec}e{exp}'.format(sign=sign, int=digits[0], dec=dec, exp=exp)

Here's an example usage:

>>> n = decimal.Decimal(4.3) ** 12314
>>> print format_decimal(n)
3.39e7800
>>> print '%e' % n

For this (and most plotting) I would not rely on the Pandas wrappers to matplotlib. Instead, just use matplotlib directly:

import matplotlib.pyplot as plt
plt.scatter(df['col_name_1'], df['col_name_2'])
plt.show() # Depending on whether you use IPython or interactive mode, etc.

and remember that you can access a NumPy array of the column's values with df.col_name_1.values for example.

I ran into trouble using this with Pandas default plotting in the case of a column of Timestamp values with millisecond precision. In trying to convert the objects to datetime64 type, I also discovered a nasty issue: < Pandas gives incorrect result when asking if Timestamp column values have attr astype >.

I would urge against using OleDB, especially if its going to be run on a server. Its likely to cost you more in the long run - eg we had a SSIS job calling a Stored Procedure with the OleDB reading an excel file in the sptroc and kept crashing the SQL box! I took the OleDB stuff out of the sproc and it stopped crashing the server.

A better method I've found is to do it with Office 2003 and the XML files - in respect of Considerations for server-side Automation of Office. Note: Office 2003 is a minimum requirement for this to fly:

Don't use SSL on port 465, it's been deprecated since 1998 and is only used by Microsoft products that didn't get the memo; use TLS on port 587 instead: So, the code below should work very well for you.

I was trying to run it on a network drive. So I increased the client_timeout in cqlsh and it worked.

Had the same issue - no body was sent from a client to a server.

Adding Content-Type header solved it for me:

var headers = new Headers();

headers.append('Accept', 'application/json'); // This one is enough for GET requests
headers.append('Content-Type', 'application/json'); // This one sends body

return fetch('/some/endpoint', {
    method: 'POST',
    mode: 'same-origin',
    credentials: 'include',
    redirect: 'follow',
    headers: headers,
    body: JSON.stringify({
        name: 'John',
        surname: 'Doe'
    }),
}).then(resp => {
    ...
}).catch(err => {
   ...
})

I had this problem once, solved with:

if (strpos($_SERVER['REQUEST_URI'], basename(__FILE__)) !== false) ...

but the ideal solution is to place the file outside of the web-server document root, as mentioned in another anwser.

The array. This array is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.

Don't use int. Files over 2 gigabytes in size are common as dirt these days

Don't use unsigned int. Files over 4 gigabytes in size are common as some slightly-less-common dirt

IIRC the standard library defines off_t as an unsigned 64 bit integer, which is what everyone should be using. We can redefine that to be 128 bits in a few years when we start having 16 exabyte files hanging around.

If you're on windows, you should use GetFileSizeEx - it actually uses a signed 64 bit integer, so they'll start hitting problems with 8 exabyte files. Foolish Microsoft! :-)

Easiest way to avoid mistakes in sanitizing input and escaping data is using PHP framework like Symfony, Nette etc. or part of that framework (templating engine, database layer, ORM).

Templating engine like Twig or Latte has output escaping on by default - you don't have to solve manually if you have properly escaped your output depending on context (HTML or Javascript part of web page).

Framework is automatically sanitizing input and you should't use $_POST, $_GET or $_SESSION variables directly, but through mechanism like routing, session handling etc.

And for database (model) layer there are ORM frameworks like Doctrine or wrappers around PDO like Nette Database.

You can read more about it here - What is a software framework?

For example, let's say that you want to create a random number between 50 and 60, you can use one of the following methods.

new Random().nextInt()%6 +55

new Random().nextInt()%6 returns a value between -5 and 5. and when you add it to 55 you can get values between 50 and 60

Second method:

Math.abs(new Random().nextInt()%11) +50

Math.abs(new Random().nextInt()%11) creates a value between 0 and 10. Later you can add 50 which in the will give you a value between 50 and 60

Another way on the command line if you are using ant is to use the android.bat script (Windows) or android script (Mac). It's in $SDK_DIR/tools.

If you say,

android.bat update project --path .  --target "android-8"

it will regenerate your build.xml, AndroidManifest.xml, etc.

I have a similar (but more complex scenario). I have a dialog, which contains a ViewPager.
One of the child pages is short, with a static height.
Another child page should always be as tall as possible.
Another child page contains a ScrollView, and the page (and thus the entire dialog) should WRAP_CONTENT if the ScrollView contents don't need the full height available to the dialog.

None of the existing answers worked completely for this specific scenario. Hold on- it's a bumpy ride.

void setupView() {
    final ViewPager.SimpleOnPageChangeListener pageChangeListener = new ViewPager.SimpleOnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {
            currentPagePosition = position;

            int decorHeight = 0;
            for (int i = 0; i < viewPager.getChildCount(); i++) {
                View child = viewPager.getChildAt(i);
                ViewPager.LayoutParams lp = (ViewPager.LayoutParams) child.getLayoutParams();
                if (lp != null && lp.isDecor) {
                    int vgrav = lp.gravity & Gravity.VERTICAL_GRAVITY_MASK;
                    boolean consumeVertical = vgrav == Gravity.TOP || vgrav == Gravity.BOTTOM;
                    if (consumeVertical) {
                        decorHeight += child.getMeasuredHeight();
                    }
                }
            }

Much thanks to @Raanan for the code to measure views and measure the decor height. I ran into problems with his library- the animation stuttered, and I think my ScrollView wouldn't scroll when the height of the dialog was short enough to require it.

If it returns "this.state is undefined" - bind timer function:

constructor(props){
    super(props);
    this.state = {currentCount: 10}
    this.timer = this.timer.bind(this)

Swift 5

button.layer.borderWidth = 2

To change the colour of the border use

button.layer.borderColor = CGColor(srgbRed: 255/255, green: 126/255, blue: 121/255, alpha: 1)

It is quite useful, when you are running on the unix platform, and need to create a text file which will be opened on the dos platform.

Unix uses '\n' as its line terminator, and dos uses '\r\n' as its line terminator, so you can use it to create a dos text file.

try

pip3 install --upgrade pandas

You could do it in one document if you had a conditional based on params sent over. Eg:

if (isset($_GET['secret_param'])) {
    <run script>
} else {
    <display button>
}

I think the best way though is to have two files.

Hi for LandscapeLeft and LandscapeRight (Update Swift 2.0)

And you have this in info

And UIController

override func shouldAutorotate() -> Bool {
    return true
}

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    return [UIInterfaceOrientationMask.LandscapeLeft,UIInterfaceOrientationMask.LandscapeRight]
}

For PortraitUpsideDown and Portrait use that

override func shouldAutorotate() -> Bool {
    if (UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeLeft ||
        UIDevice.currentDevice().orientation == UIDeviceOrientation.LandscapeRight ||
        UIDevice.currentDevice().orientation == UIDeviceOrientation.Unknown) {
            return false
    }
    else {
        return true
    }
}

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
    return [UIInterfaceOrientationMask.Portrait ,UIInterfaceOrientationMask.PortraitUpsideDown]
}

Message from France, Merry Christmas !

Edit :

Other solution :

extension UINavigationController {
    public override func shouldAutorotate() -> Bool {
        if visibleViewController is MyViewController {
            return true   // rotation
        } else {
            return false  // no rotation
        }
    }

    public override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
        return (visibleViewController?.supportedInterfaceOrientations())!
    }
}

As per hobodave's post: "Set to a non-empty value if the script was queried through the HTTPS protocol."

if (!empty($_SERVER['HTTPS']))
{
    $secure_connection = true;
}

I usually don't specify height, but do specify width: ... and rows and cols.

Usually, in my cases, only width and rows are needed, for the textarea to look nice in relation to other elems. (And cols is a fallback if someone doesn't use CSS, as explained in the other answers.)

((Specifying both rows and height feels a little bit like duplicating data I think?))

You can avoid a useless use of cat and handle mismatched quotes better with this:

$ read -r -d '' VAR <<'EOF'
abc'asdf"
$(dont-execute-this)
foo"bar"''
EOF

If you don't quote the variable when you echo it, newlines are lost. Quoting it preserves them:

$ echo "$VAR"
abc'asdf"
$(dont-execute-this)
foo"bar"''

If you want to use indentation for readability in the source code, use a dash after the less-thans. The indentation must be done using only tabs (no spaces).

$ read -r -d '' VAR <<-'EOF'
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''
    EOF
$ echo "$VAR"
abc'asdf"
$(dont-execute-this)
foo"bar"''

If, instead, you want to preserve the tabs in the contents of the resulting variable, you need to remove tab from IFS. The terminal marker for the here doc (EOF) must not be indented.

$ IFS='' read -r -d '' VAR <<'EOF'
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''
EOF
$ echo "$VAR"
    abc'asdf"
    $(dont-execute-this)
    foo"bar"''

Tabs can be inserted at the command line by pressing Ctrl-V Tab. If you are using an editor, depending on which one, that may also work or you may have to turn off the feature that automatically converts tabs to spaces.

Version 1:

// Update data of question values with $data from formulay
$Q1 = Question::find($id);
$Q1->fill($data);
$Q1->push();

Version 2:

$Q1 = Question::find($id);
$Q1->field = 'YOUR TEXT OR VALUE';
$Q1->save();

In case of answered question you can use them:

$page = Page::find($id);
$page2update = $page->where('image', $path);
$page2update->image = 'IMGVALUE';
$page2update->save();

url=url.substring(1,url.Length-1);

This way you can use the directories if it is like .../.../.../... etc.

You must have an application associated with the file type. You must be in the folder that houses the file. In gitbash: start file.extension

string a = @"a\\b";
a = a.Replace(@"\\",@"\");

should work. Remember that in the watch Visual STudio show the "\" escaped so you see "\" in place of a single one.

HashMap basically contains Entry which subsequently contains Key(Object) and Value(Object).Internally HashSet are HashMap and HashMap do replace values as some of you already pointed..but does it really replaces the keys???No ..and that is the trick here. HashMap keeps its value as key in the underlying HashMap and value is just a dummy object.So if u try to reinsert same Value in HashMap(Key in underlying Map).It just replaces the dummy value and not the Key(Value for HashSet).

Look at the below code for HashSet Class:

public boolean  [More ...] add(E e) {

   return map.put(e, PRESENT)==null;
}

Here e is the value for HashSet but key for underlying map.and key is never replaced. Hope i am able to clear the confusion.

You want to set style

margin: auto;

And remove the positioning styles (top, left, position)

I know this will center horrizontaly but I'm not sure about vertical!

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

Using single quotes for keys are not allowed in JSON. You need to use double quotes.

For your use-case perhaps this would be the easiest solution:

str = '{"a":1}';

Source:

If a property requires quotes, double quotes must be used. All property names must be surrounded by double quotes.

You have to give width:100% to parent to center the text.

 .parent {_x000D_
   display: flex;_x000D_
   justify-content: center;_x000D_
   position: absolute;_x000D_
   width:100%_x000D_
 }

<div class="parent">_x000D_
  <div class="child">text</div>_x000D_
</div>

If you also need to centre align vertically, give height:100% and align-itens: center

.parent {
   display: flex;
   justify-content: center;
   align-items: center;
   position: absolute;
   width:100%;
   height: 100%;
 }

Here is a fetch POST example. You can do the same for DELETE.

function createNewProfile(profile) {
    const formData = new FormData();
    formData.append('first_name', profile.firstName);
    formData.append('last_name', profile.lastName);
    formData.append('email', profile.email);

    return fetch('http://example.com/api/v1/registration', {
        method: 'POST',
        body: formData
    }).then(response => response.json())
}

createNewProfile(profile)
   .then((json) => {
       // handle success
    })
   .catch(error => error);

Here's mine:

set statusline=
set statusline +=%1*\ %n\ %*            "buffer number
set statusline +=%5*%{&ff}%*            "file format
set statusline +=%3*%y%*                "file type
set statusline +=%4*\ %<%F%*            "full path
set statusline +=%2*%m%*                "modified flag
set statusline +=%1*%=%5l%*             "current line
set statusline +=%2*/%L%*               "total lines
set statusline +=%1*%4v\ %*             "virtual column number
set statusline +=%2*0x%04B\ %*          "character under cursor

And here's the colors I used:

hi User2 guifg=#dd3333 guibg=#222222
hi User3 guifg=#ff66ff guibg=#222222

hi User5 guifg=#eeee40 guibg=#222222

IISReset restarts the entire webserver (including all associated sites). If you're just looking to reset a single ASP.NET website, you should just recycle that Application Domain.

None of the above solutions worked for me. What finally worked was:

Instead of

import android.support.v4.content.FileProvider;

Use this

import androidx.core.content.FileProvider;

This path is updated as of AndroidX (the repackaged Android Support Library).

You don't encode the entire URL, only parts of it that come from "unreliable sources".

• Java:

  String query = URLEncoder.encode("apples oranges", "utf-8");
  String url = "http://stackoverflow.com/search?q=" + query;
  

• Kotlin:

  val query: String = URLEncoder.encode("apples oranges", "utf-8")
  val url = "http://stackoverflow.com/search?q=$query"
  

Alternatively, you can use Strings.urlEncode(String str) of DroidParts that doesn't throw checked exceptions.

Or use something like

String uri = Uri.parse("http://...")
                .buildUpon()
                .appendQueryParameter("key", "val")
                .build().toString();

I had to do it on DOM ready

$( document ).ready(function () { // this has to be done after the document has been rendered
    $("[data-toggle='tooltip']").tooltip({html: true}); // enable bootstrap 3 tooltips
    $('[data-toggle="popover"]').popover({
        trigger: 'hover',
        'placement': 'top',
        'show': true
    });
});

And change my load orders to be:

• jQuery
• jQuery UI
• Bootstrap

Easiest way for me ->

        echo "Hello my name is Donald" | sed  s/\ //g

What is the length of str array, and with how much 0s it is ending?

Let's find out:

int main() {
  char str[] = "Hello\0";
  int length = sizeof str / sizeof str[0];
  // "sizeof array" is the bytes for the whole array (must use a real array, not
  // a pointer), divide by "sizeof array[0]" (sometimes sizeof *array is used)
  // to get the number of items in the array
  printf("array length: %d\n", length);
  printf("last 3 bytes: %02x %02x %02x\n",
         str[length - 3], str[length - 2], str[length - 1]);
  return 0;
}

To Whom, deailing with share hosting environment and still chance to have Current PHP less than 7.0 Who does not have dirname( __FILE__, 2 ); it is possible to use following.

function dirname_safe($path, $level = 0){
    $dir = explode(DIRECTORY_SEPARATOR, $path);
    $level = $level * -1;
    if($level == 0) $level = count($dir);
    array_splice($dir, $level);
    return implode($dir, DIRECTORY_SEPARATOR).DIRECTORY_SEPARATOR;
}

print_r(dirname_safe(__DIR__, 2));

Although the solution you referred to uses jquery, mouseenter and mouseleave are native dom events, so you might use without jquery.

From the Java Language Specification:

• Each class variable, instance variable, or array component is initialized with a default value when it is created (§15.9, §15.10):

  • For type byte, the default value is zero, that is, the value of (byte)0.
  • For type short, the default value is zero, that is, the value of (short)0.
  • For type int, the default value is zero, that is, 0.
  • For type long, the default value is zero, that is, 0L.
  • For type float, the default value is positive zero, that is, 0.0f.
  • For type double, the default value is positive zero, that is, 0.0d.
  • For type char, the default value is the null character, that is, '\u0000'.
  • For type boolean, the default value is false.
  • For all reference types (§4.3), the default value is null.

I know this is old, but the solutions here seem rather verbose. Just an easily readable one-liner if you have a URL or URI:

String filename = new File(url.getPath()).getName();

Or if you have a String:

String filename = new File(new URL(url).getPath()).getName();

TypeScript supports structural typing (also called duck typing), meaning that types are compatible when they share the same members. Your problem is that Apple and Pear don't share all their members, which means that they are not compatible. They are however compatible to another type that has only the isDecayed: boolean member. Because of structural typing, you don' need to inherit Apple and Pear from such an interface.

There are different ways to assign such a compatible type:

Assign type during variable declaration

This statement is implicitly typed to Apple[] | Pear[]:

const fruits = fruitBasket[key];

You can simply use a compatible type explicitly in in your variable declaration:

const fruits: { isDecayed: boolean }[] = fruitBasket[key];

For additional reusability, you can also define the type first and then use it in your declaration (note that the Apple and Pear interfaces don't need to be changed):

type Fruit = { isDecayed: boolean };
const fruits: Fruit[] = fruitBasket[key];

Cast to compatible type for the operation

The problem with the given solution is that it changes the type of the fruits variable. This might not be what you want. To avoid this, you can narrow the array down to a compatible type before the operation and then set the type back to the same type as fruits:

const fruits: fruitBasket[key];
const freshFruits = (fruits as { isDecayed: boolean }[]).filter(fruit => !fruit.isDecayed) as typeof fruits;

Or with the reusable Fruit type:

type Fruit = { isDecayed: boolean };
const fruits: fruitBasket[key];
const freshFruits = (fruits as Fruit[]).filter(fruit => !fruit.isDecayed) as typeof fruits;

The advantage of this solution is that both, fruits and freshFruits will be of type Apple[] | Pear[].

with momentjs i use

moment(value).format("YYYY-MM-DDTHH:mm:ss")

The comparison needs to be evaluated fully inside EL ${ ... }, not outside.

<c:if test="${values.type eq 'object'}">

As to the docs, those ${} things are not JSTL, but EL (Expression Language) which is a whole subject at its own. JSTL (as every other JSP taglib) is just utilizing it. You can find some more EL examples here.

<c:if test="#{bean.booleanValue}" />
<c:if test="#{bean.intValue gt 10}" />
<c:if test="#{bean.objectValue eq null}" />
<c:if test="#{bean.stringValue ne 'someValue'}" />
<c:if test="#{not empty bean.collectionValue}" />
<c:if test="#{not bean.booleanValue and bean.intValue ne 0}" />
<c:if test="#{bean.enumValue eq 'ONE' or bean.enumValue eq 'TWO'}" />

See also:

• Our EL wiki page

By the way, unrelated to the concrete problem, if I guess your intent right, you could also just call Object#getClass() and then Class#getSimpleName() instead of adding a custom getter.

<c:forEach items="${list}" var="value">
    <c:if test="${value['class'].simpleName eq 'Object'}">
        <!-- code here -->
    </c:if>
</c:forEeach>

If you have an ES2015 environment (as of this writing: io.js, IE11, Chrome, Firefox, WebKit nightly), then the following will work, and will be fast (viz. O(n)):

function hasDuplicates(array) {
    return (new Set(array)).size !== array.length;
}

If you only need string values in the array, the following will work:

function hasDuplicates(array) {
    var valuesSoFar = Object.create(null);
    for (var i = 0; i < array.length; ++i) {
        var value = array[i];
        if (value in valuesSoFar) {
            return true;
        }
        valuesSoFar[value] = true;
    }
    return false;
}

We use a "hash table" valuesSoFar whose keys are the values we've seen in the array so far. We do a lookup using in to see if that value has been spotted already; if so, we bail out of the loop and return true.

If you need a function that works for more than just string values, the following will work, but isn't as performant; it's O(n²) instead of O(n).

function hasDuplicates(array) {
    var valuesSoFar = [];
    for (var i = 0; i < array.length; ++i) {
        var value = array[i];
        if (valuesSoFar.indexOf(value) !== -1) {
            return true;
        }
        valuesSoFar.push(value);
    }
    return false;
}

The difference is simply that we use an array instead of a hash table for valuesSoFar, since JavaScript "hash tables" (i.e. objects) only have string keys. This means we lose the O(1) lookup time of in, instead getting an O(n) lookup time of indexOf.

Why is that not acceptable?

document.getElementById('test').innerHTML += str

would be the textbook way of doing it.

Operator precedence in python
You can see that not X has higher precedence than and. Which means that the not only apply to the first part (u0 <= u). Write:

if not (u0 <= u and u < u0+step):  

or even

if not (u0 <= u < u0+step):  

Two ways to read file into list in python (note these are not either or) -

1. use of with - supported from python 2.5 and above
2. use of list comprehensions

1. use of with

This is the pythonic way of opening and reading files.

#Sample 1 - elucidating each step but not memory efficient
lines = []
with open("C:\name\MyDocuments\numbers") as file:
    for line in file: 
        line = line.strip() #or some other preprocessing
        lines.append(line) #storing everything in memory!

#Sample 2 - a more pythonic and idiomatic way but still not memory efficient
with open("C:\name\MyDocuments\numbers") as file:
    lines = [line.strip() for line in file]

#Sample 3 - a more pythonic way with efficient memory usage. Proper usage of with and file iterators. 
with open("C:\name\MyDocuments\numbers") as file:
    for line in file:
        line = line.strip() #preprocess line
        doSomethingWithThisLine(line) #take action on line instead of storing in a list. more memory efficient at the cost of execution speed.

the .strip() is used for each line of the file to remove \n newline character that each line might have. When the with ends, the file will be closed automatically for you. This is true even if an exception is raised inside of it.

2. use of list comprehension

This could be considered inefficient as the file descriptor might not be closed immediately. Could be a potential issue when this is called inside a function opening thousands of files.

data = [line.strip() for line in open("C:/name/MyDocuments/numbers", 'r')]

Note that file closing is implementation dependent. Normally unused variables are garbage collected by python interpreter. In cPython (the regular interpreter version from python.org), it will happen immediately, since its garbage collector works by reference counting. In another interpreter, like Jython or Iron Python, there may be a delay.

You call writer.close(); in writeToFile so the writer has been closed the second time you call writeToFile.

Why don't you merge FileStatus into writeToFile?

select * from table order by length(column);

Documentation on the length() function, as well as all the other string functions, is available here.

If you want an efficient search that is often repeated, first sort the array (Array.Sort) and then use Array.BinarySearch.

You have a lot of type-mismatches in your code such as trying to put an int value where BigDecimal is required. The corrected version of your code:

public class Payment
{
    BigDecimal itemCost  = BigDecimal.ZERO;
    BigDecimal totalCost = BigDecimal.ZERO;

    public BigDecimal calculateCost(int itemQuantity, BigDecimal itemPrice)
    {
        itemCost  = itemPrice.multiply(new BigDecimal(itemQuantity));
        totalCost = totalCost.add(itemCost);
        return totalCost;
    }
}

You can use:

JsonConvert.PopulateObject(json, obj);

here: json is the json string,obj is the target object. See: example

Note: PopulateObject() will not erase obj's list data, after Populate(), obj's list member will contains its original data and data from json string

To move up a directory, the quickest way would be to add an alias to ~/.bash_profile

alias ..='cd ..'

and then one would need only to type '..[return]'.

I think it would be smart to only show the hand/pointer cursor when JavaScript is available. So people will not have the feeling they can click on something that is not clickable.

To achieve that you could use the JavaScript libary jQuery to add the CSS to the element like so

$("li").css({"cursor":"pointer"});

Or chain it directly to the click handler.

Or when modernizer in combination with <html class="no-js"> is used, the CSS would look like this:

.js li { cursor: pointer; }

If the audio wrapped into the avi is not mp3-format to start with, you may need to specify -acodec mp3 as an additional parameter. Or whatever your mp3 codec is (on Linux systems its probably -acodec libmp3lame). You may also get the same effect, platform-agnostic, by instead specifying -f mp3 to "force" the format to mp3, although not all versions of ffmpeg still support that switch. Your Mileage May Vary.

You can't see this method in javadoc because it's added by the compiler.

Documented in three places :

• Enum Types, from The Java Tutorials

The compiler automatically adds some special methods when it creates an enum. For example, they have a static values method that returns an array containing all of the values of the enum in the order they are declared. This method is commonly used in combination with the for-each construct to iterate over the values of an enum type.

• Enum.valueOf class
  (The special implicit values method is mentioned in description of valueOf method)

All the constants of an enum type can be obtained by calling the implicit public static T[] values() method of that type.

• Enum Types, Section 8.9, Java Language Specification

The values function simply list all values of the enumeration.
