Programs & Examples On #Py2app

you may want to see if your app can run under IronPython. If so, you can compile it to an exe http://www.codeplex.com/IronPython

I really like those libraries mentioned here but I had an idea that could be simpler than just padding or doing tons of string manipulations,

You could just manually set your cursor using the maximum string length of your data. Here's some code to get the idea (not tested):

var column1[] = {"test", "longer test", "etc"}
var column2[] = {"data", "more data", "etc"}
var offset = strings.OrderByDescending(s => s.Length).First().Length;
for (var i = 0; i < column.Length; i++) {
    Console.Write(column[i]);
    Console.CursorLeft = offset + 1;
    Console.WriteLine(column2[i]);
}

you could easily extrapolate if you have more rows.

It is retrievable from Javascript - as window.location.hash. From there you could send it to the server with Ajax for example, or encode it and put it into URLs which can then be passed through to the server-side.

As of MySQL 5.7.6, use ALTER USER

Example:

ALTER USER 'username' IDENTIFIED BY 'password';

Because:

• SET PASSWORD ... = PASSWORD('auth_string') syntax is deprecated as of MySQL 5.7.6 and will be removed in a future MySQL release.

• SET PASSWORD ... = 'auth_string' syntax is not deprecated, but ALTER USER is now the preferred statement for assigning passwords.

You can also throw a std::system_error as shown in the test code below. This method seems to produce more readable output than f.exception(...).

#include <exception> // <-- requires this
#include <fstream>
#include <iostream>

void process(const std::string& fileName) {
    std::ifstream f;
    f.open(fileName);

    // after open, check f and throw std::system_error with the errno
    if (!f)
        throw std::system_error(errno, std::system_category(), "failed to open "+fileName);

    std::clog << "opened " << fileName << std::endl;
}

int main(int argc, char* argv[]) {
    try {
        process(argv[1]);
    } catch (const std::system_error& e) {
        std::clog << e.what() << " (" << e.code() << ")" << std::endl;
    }
    return 0;
}

Example output (Ubuntu w/clang):

$ ./test /root/.profile
failed to open /root/.profile: Permission denied (system:13)
$ ./test missing.txt
failed to open missing.txt: No such file or directory (system:2)
$ ./test ./test
opened ./test
$ ./test $(printf '%0999x')
failed to open 000...000: File name too long (system:36)

Using np.ix_ is the most convenient way to do it (as answered by others), but here is another interesting way to do it:

>>> rows = [0, 1, 3]
>>> cols = [0, 2]

>>> a[rows].T[cols].T

array([[ 0,  2],
       [ 4,  6],
       [12, 14]])

You can do this using Input.setSelectionRange, part of the Range API for interacting with text selections and the text cursor:

var searchInput = $('#Search');

// Multiply by 2 to ensure the cursor always ends up at the end;
// Opera sometimes sees a carriage return as 2 characters.
var strLength = searchInput.val().length * 2;

searchInput.focus();
searchInput[0].setSelectionRange(strLength, strLength);

Demo: Fiddle

The managed wrapper for the HTML document doesn't completely implement the functionality you need, so you need to dip into the MSHTML API to accomplish what you want:

1) Add a reference to MSHTML, which will probalby be called "Microsoft HTML Object Library" under COM references.

2) Add 'using mshtml;' to your namespaces.

3) Get a reference to your script element's IHTMLElement:

IHTMLElement iScriptEl = (IHTMLElement)scriptEl.DomElement;

4) Call the insertAdjacentText method, with the first parameter value of "afterBegin". All the possible values are listed here:

iScriptEl.insertAdjacentText("afterBegin", "function sayHello() { alert('hello') }");

5) Now you'll be able to see the code in the scriptEl.InnerText property.

Simply, for me, I used ion-row and ion-col to achieve it. You can make it more neater by doing some changes by CSS.

<ion-row style="border-bottom: groove;">
      <ion-col col-4>
      <ion-label >header</ion-label>
    </ion-col>
    <ion-col col-4>
      <ion-label >header</ion-label>
    </ion-col>
      <ion-col col-4>
      <ion-label >header</ion-label>
    </ion-col>
  </ion-row>
  <ion-row style="border-bottom: groove;">
      <ion-col col-4>
      <ion-label >row</ion-label>
    </ion-col>
    <ion-col col-4>
      <ion-label >02/02/2018</ion-label>
    </ion-col>
      <ion-col col-4>
      <ion-label >row</ion-label>
    </ion-col>
  </ion-row>
  <ion-row style="border-bottom: groove;">
      <ion-col col-4>
      <ion-label >row</ion-label>
    </ion-col>
    <ion-col col-4>
      <ion-label >02/02/2018</ion-label>
    </ion-col>
      <ion-col col-4>
      <ion-label >row</ion-label>
    </ion-col>
  </ion-row>
  <ion-row >
      <ion-col col-4>
      <ion-label >row</ion-label>
    </ion-col>
    <ion-col col-4>
      <ion-label >02/02/2018</ion-label>
    </ion-col>
      <ion-col col-4>
      <ion-label >row</ion-label>
    </ion-col>
  </ion-row>

Order of arguments to java command is also important:

Use the sizing utility classes...

• h-50 = height 50%
• h-100 = height 100%

UPDATE: Please see Dylan's or d.c's anwer for a little easier (and more stable) solution, which does not rely on Chrome beeing installed in LocalAppData!

Even if I agree with Daniel Hilgarth to open a new tab in chrome you just need to execute chrome.exe with your URL as the argument:

Process.Start(@"%AppData%\..\Local\Google\Chrome\Application\chrome.exe", 
              "http:\\www.YourUrl.com");

You need to specify all of the names, including those already registered.

I used the following command originally to register some certificates:

/opt/certbot/certbot-auto certonly --webroot --agree-tos -w /srv/www/letsencrypt/ \
--email [email protected] \
--expand -d example.com,www.example.com

... and just now I successfully used the following command to expand my registration to include a new subdomain as a SAN:

/opt/certbot/certbot-auto certonly --webroot --agree-tos -w /srv/www/letsencrypt/ \
--expand -d example.com,www.example.com,click.example.com

From the documentation:

--expand "If an existing cert covers some subset of the requested names, always expand and replace it with the additional names."

Don't forget to restart the server to load the new certificates if you are running nginx.

If you just want a string/json to print it can be solved with:

print(df.to_string(index=False))

Buf if you want to serialize the data too or even send to a MongoDB, would be better to do something like:

document = df.to_dict(orient='list')

There are 6 ways by now to orient the data, check more in the panda docs which better fits you.

Put your Thread.sleep in a try catch block

try {
    //thread to sleep for the specified number of milliseconds
    Thread.sleep(100);
} catch ( java.lang.InterruptedException ie) {
    System.out.println(ie);
}

As of now Android 4.2.2 platform includes Google Play services. Just use an emulator running Jelly Bean. Details can be found here:

Setup Google Play Services SDK

EDIT:

Another option is to use Genymotion (runs way faster)

EDIT 2:

As @gdw2 commented: "setting up the Google Play Services SDK does not install a working Google Play app -- it just enables certain services provided by the SDK"

After version 2.0 Genymotion does not come with Play Services by default, but it can be easily installed manually. Just download the right version from here and drag and drop into the virtual device (emulador).

probleme : unit test result are not the same runing with eclipse and maven due ti order of library used by eclipse and maven. In my case the test was success with maven but i want to debug my unit test using eclipse, so the most easy way to debug unit test class with eclipse and runing maven is :

1) mvn -Dtest=MySuperClassTest -Dmaven.surefire.debug test ==> it will listen to the 5005 port (default port)

2) Go to eclipse, open a debug configuration, add a new java remote application and change the port to 5005 and debug

3) of course you must add break point somewhere in the class that you want to debug

I found the following algorithm provides a very good statistical distribution. Each input bit affects each output bit with about 50% probability. There are no collisions (each input results in a different output). The algorithm is fast except if the CPU doesn't have a built-in integer multiplication unit. C code, assuming int is 32 bit (for Java, replace >> with >>> and remove unsigned):

unsigned int hash(unsigned int x) {
    x = ((x >> 16) ^ x) * 0x45d9f3b;
    x = ((x >> 16) ^ x) * 0x45d9f3b;
    x = (x >> 16) ^ x;
    return x;
}

The magic number was calculated using a special multi-threaded test program that ran for many hours, which calculates the avalanche effect (the number of output bits that change if a single input bit is changed; should be nearly 16 on average), independence of output bit changes (output bits should not depend on each other), and the probability of a change in each output bit if any input bit is changed. The calculated values are better than the 32-bit finalizer used by MurmurHash, and nearly as good (not quite) as when using AES. A slight advantage is that the same constant is used twice (it did make it slightly faster the last time I tested, not sure if it's still the case).

You can reverse the process (get the input value from the hash) if you replace the 0x45d9f3b with 0x119de1f3 (the multiplicative inverse):

unsigned int unhash(unsigned int x) {
    x = ((x >> 16) ^ x) * 0x119de1f3;
    x = ((x >> 16) ^ x) * 0x119de1f3;
    x = (x >> 16) ^ x;
    return x;
}

For 64-bit numbers, I suggest to use the following, even thought it might not be the fastest. This one is based on splitmix64, which seems to be based on the blog article Better Bit Mixing (mix 13).

uint64_t hash(uint64_t x) {
    x = (x ^ (x >> 30)) * UINT64_C(0xbf58476d1ce4e5b9);
    x = (x ^ (x >> 27)) * UINT64_C(0x94d049bb133111eb);
    x = x ^ (x >> 31);
    return x;
}

For Java, use long, add L to the constant, replace >> with >>> and remove unsigned. In this case, reversing is more complicated:

uint64_t unhash(uint64_t x) {
    x = (x ^ (x >> 31) ^ (x >> 62)) * UINT64_C(0x319642b2d24d8ec3);
    x = (x ^ (x >> 27) ^ (x >> 54)) * UINT64_C(0x96de1b173f119089);
    x = x ^ (x >> 30) ^ (x >> 60);
    return x;
}

Update: You may also want to look at the Hash Function Prospector project, where other (possibly better) constants are listed.

Use the parse_url() and parse_str() methods. parse_url() will parse a URL string into an associative array of its parts. Since you only want a single part of the URL, you can use a shortcut to return a string value with just the part you want. Next, parse_str() will create variables for each of the parameters in the query string. I don't like polluting the current context, so providing a second parameter puts all the variables into an associative array.

$url = "https://mysite.com/test/[email protected]&testin=123";
$query_str = parse_url($url, PHP_URL_QUERY);
parse_str($query_str, $query_params);
print_r($query_params);

//Output: Array ( [email] => [email protected] [testin] => 123 ) 

To create frames from video:

ffmpeg\ffmpeg -i %video% test\thumb%04d.jpg -hide_banner

Optional: remove frames you don't want in output video
(more accurate than trimming video with -ss & -t)

Then create video from image/frames eg.:

ffmpeg\ffmpeg -framerate 30 -start_number 56 -i test\thumb%04d.jpg -vf format=yuv420p test/output.mp4

The format you've used is not recognized by strtotime(). Replace

$date = "04-15-2013";

by

$date = "04/15/2013";

Or if you want to use - then use the following line with the year in front:

$date = "2013-04-15";

I found that this issue was related only to the code signing and certificates not the code itself. To verify this, create the basic single view app and try to run it without any changes to your device. If you see the same error type this shows your code is fine. Like me you will find that your certificates are invalid. Download all again and fix any expired ones. Then when you get the basic app to not report the error try your app again after exiting Xcode and perhaps restarting your mac for good measure. That finally put this nightmare to an end. Most likely this has nothing to do with your code especially if you get Build Successful message when you try to run it. FYI

Add a Primary Key (code below)

Run the correct delete (code below)

Consider WHY you woudln't want to keep that primary key.

Assuming MSSQL or compatible:

ALTER TABLE Employee ADD EmployeeID int identity(1,1) PRIMARY KEY;

WHILE EXISTS (SELECT COUNT(*) FROM Employee GROUP BY EmpID, EmpSSN HAVING COUNT(*) > 1)
BEGIN
    DELETE FROM Employee WHERE EmployeeID IN 
    (
        SELECT MIN(EmployeeID) as [DeleteID]
        FROM Employee
        GROUP BY EmpID, EmpSSN
        HAVING COUNT(*) > 1
    )
END

Sorted() solution can give you some unexpected results with other strings.

List of other solutions:

Sort letters and make them distinct:

>>> s = "Bubble Bobble"
>>> ''.join(sorted(set(s.lower())))
' belou'

Sort letters and make them distinct while keeping caps:

>>> s = "Bubble Bobble"
>>> ''.join(sorted(set(s)))
' Bbelou'

Sort letters and keep duplicates:

>>> s = "Bubble Bobble"
>>> ''.join(sorted(s))
' BBbbbbeellou'

If you want to get rid of the space in the result, add strip() function in any of those mentioned cases:

>>> s = "Bubble Bobble"
>>> ''.join(sorted(set(s.lower()))).strip()
'belou'

You could test the url via AJAX and read the status code - that is if the URL is in the same domain.

If it's a remote domain, you could have a server script on your own domain check out a remote URL.

I figured it out, and it's actually pretty straight forward.

Set your variable:

$image1 = "img/products/image1.jpg";

Then ceate a cell, position it, then rather than setting where the image is, use the variable you created above with the following:

$this->Cell( 40, 40, $pdf->Image($image1, $pdf->GetX(), $pdf->GetY(), 33.78), 0, 0, 'L', false );

Now the cell will move up and down with content if other cells around it move.

Hope this helps others in the same boat.

Update your user, domain, and proxy information in cntlm.ini, then test your proxy with this command (run in your Cntlm installation folder):

cntlm -c cntlm.ini -I -M http://google.ro

It will ask for your password, and hopefully print your required authentication information, which must be saved in your cntlm.ini

Sample cntlm.ini:

Username            user
Domain              domain

# provide actual value if autodetection fails
# Workstation         pc-name

Proxy               my_proxy_server.com:80
NoProxy             127.0.0.*, 192.168.*

Listen              127.0.0.1:54321
Listen              192.168.1.42:8080
Gateway             no

SOCKS5Proxy         5000
# provide socks auth info if you want it
# SOCKS5User          socks-user:socks-password

# printed authentication info from the previous step
Auth            NTLMv2
PassNTLMv2      98D6986BCFA9886E41698C1686B58A09

Note: on linux the config file is cntlm.conf

The easiest way to do so is using jQuery and animate.css animation library.

Javascript

/* --- Show DIV --- */
$( '.example' ).removeClass( 'fadeOutRight' ).show().addClass( 'fadeInRight' );

/* --- Hide DIV --- */
$( '.example' ).removeClass( 'fadeInRight' ).addClass( 'fadeOutRight' );

HTML

<div class="example">Some text over here.</div>

Easy enough to implement. Just don't forget to include the animate.css file in the header :)

This code works for me:

    Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); 
    config.AppSettings.Settings["test"].Value = "blah";       
    config.Save(ConfigurationSaveMode.Modified);
    ConfigurationManager.RefreshSection("appSettings");

Note: it doesn't update the solution item 'app.config', but the '.exe.config' one in the bin/ folder if you run it with F5.

you can use the new push/pop state functions in the history manipulation API.

Here is a function that does the conversion of a PDF file with one or multiple pages to a single merged JPEG image.

import os
import tempfile
from pdf2image import convert_from_path
from PIL import Image

def convert_pdf_to_image(file_path, output_path):
    # save temp image files in temp dir, delete them after we are finished
    with tempfile.TemporaryDirectory() as temp_dir:
        # convert pdf to multiple image
        images = convert_from_path(file_path, output_folder=temp_dir)
        # save images to temporary directory
        temp_images = []
        for i in range(len(images)):
            image_path = f'{temp_dir}/{i}.jpg'
            images[i].save(image_path, 'JPEG')
            temp_images.append(image_path)
        # read images into pillow.Image
        imgs = list(map(Image.open, temp_images))
    # find minimum width of images
    min_img_width = min(i.width for i in imgs)
    # find total height of all images
    total_height = 0
    for i, img in enumerate(imgs):
        total_height += imgs[i].height
    # create new image object with width and total height
    merged_image = Image.new(imgs[0].mode, (min_img_width, total_height))
    # paste images together one by one
    y = 0
    for img in imgs:
        merged_image.paste(img, (0, y))
        y += img.height
    # save merged image
    merged_image.save(output_path)
    return output_path

Example usage: -

convert_pdf_to_image("path_to_Pdf/1.pdf", "output_path/output.jpeg")

var data = 'json string ?';

Explanation

You got different things here:

First:

• If you use a service you will get the instance of a function ("this" keyword).
• If you use a factory you will get the value that is returned by invoking the function reference (the return statement in factory).

ref: angular.service vs angular.factory

Second:

Keep in mind all providers in AngularJS (value, constant, services, factories) are singletons!

Third:

Using one or the other (service or factory) is about code style. But, the common way in AngularJS is to use factory.

Why ?

Because "The factory method is the most common way of getting objects into AngularJS dependency injection system. It is very flexible and can contain sophisticated creation logic. Since factories are regular functions, we can also take advantage of a new lexical scope to simulate "private" variables. This is very useful as we can hide implementation details of a given service."

(ref: http://www.amazon.com/Mastering-Web-Application-Development-AngularJS/dp/1782161821).

Usage

Service : Could be useful for sharing utility functions that are useful to invoke by simply appending () to the injected function reference. Could also be run with injectedArg.call(this) or similar.

Factory : Could be useful for returning a ‘class’ function that can then be new`ed to create instances.

So, use a factory when you have complex logic in your service and you don't want expose this complexity.

In other cases if you want to return an instance of a service just use service.

But you'll see with time that you'll use factory in 80% of cases I think.

For more details: http://blog.manishchhabra.com/2013/09/angularjs-service-vs-factory-with-example/

UPDATE :

Excellent post here : http://iffycan.blogspot.com.ar/2013/05/angular-service-or-factory.html

"If you want your function to be called like a normal function, use factory. If you want your function to be instantiated with the new operator, use service. If you don't know the difference, use factory."

UPDATE :

AngularJS team does his work and give an explanation: http://docs.angularjs.org/guide/providers

And from this page :

"Factory and Service are the most commonly used recipes. The only difference between them is that Service recipe works better for objects of custom type, while Factory can produce JavaScript primitives and functions."

With REGEXP_SUBSTR is as simple as:

SELECT REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 1) col_one,
       REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 2) col_two
FROM YOUR_TABLE t;

Just try with

$("._statusDDL").val("2");

and not with

$("._statusDDL").val(2);

Also, It can be done with LINQ

var str = "Hello@Hello&Hello(Hello)";
var characters = str.Select(c => char.IsLetter(c) ? c : ',')).ToArray();             
var output = new string(characters);
Console.WriteLine(output);

This is a solution/hack I'm using:

tasks/main.yml:

- name: parametrized template - a
  template:
    src: test.j2
    dest: /tmp/templateA
  with_items: var_a

- name: parametrized template - b
  template:
    src: test.j2
    dest: /tmp/templateB
  with_items: var_b

vars/main.yml

var_a:
  - 'this is var_a'
var_b:
  - 'this is var_b'

templates/test.j2:

{{ item }}

After running this, you get this is var_a in /tmp/templateA and this is var_b in /tmp/templateB.

Basically you abuse with_items to render the template with each item in the one-item list. This works because you can control what the list is when using with_items.

The downside of this is that you have to use item as the variable name in you template.

If you want to pass more than one variable this way, you can dicts as your list items like this:

var_a:
  -
    var_1: 'this is var_a1'
    var_2: 'this is var_a2'
var_b:
  -
    var_1: 'this is var_b1'
    var_2: 'this is var_b2'

and then refer to them in your template like this:

{{ item.var_1 }}
{{ item.var_2 }}

Use the formatting options available to you, use the Decimal format string. It is far more flexible and requires little to no maintenance compared to direct string manipulation.

To get the string representation using at least 4 digits:

int length = 4;
int number = 50;
string asString = number.ToString("D" + length); //"0050"

SHOW TABLE STATUS WHERE Name = 'xxx'

This will give you (among other things) an Engine column, which is what you want.

If you already have checked out the code, the files are already indexed. After changing your git settings, say by running:

git config --global core.autocrlf input 

you should refresh the indexes with

git rm --cached -r . 

and re-write git index with

git reset --hard

https://help.github.com/articles/dealing-with-line-endings/#refreshing-a-repository-after-changing-line-endings

Note: this is will remove your local changes, consider stashing them before you do this.

Use the following:

var enteredText = document.getElementById("textArea").value;
var numberOfLineBreaks = (enteredText.match(/\n/g)||[]).length;
alert('Number of breaks: ' + numberOfLineBreaks);

DEMO

Now what I did was to split the string first using linebreaks, and then split it again like you did before. Note: you can also use jQuery combined with regex for this:

var splitted = $('#textArea').val().split("\n");           // will split on line breaks

Hope that helps you out!

From the terminal run:

  sudo apt-get install python3-numpy

This package contains Numpy for Python 3.

For scipy:

 sudo apt-get install python3-scipy

For for plotting graphs use pylab:

 sudo apt-get install python3-matplotlib

The practical use of this construct? It is a javascript replaceAll() on strings.

var s = 'stackoverflow_is_cool';  
s = s.split('_').join(' ');  
console.log(s);

will output:

stackoverflow is cool

The word check_ in the name means that if the command (the shell in this case that returns the exit status of the last command (yum in this case)) returns non-zero status then it raises CalledProcessError exception. It is by design. If the command that you want to run may return non-zero status on success then either catch this exception or don't use check_ methods. You could use subprocess.call in your case because you are ignoring the captured output, e.g.:

import subprocess

rc = subprocess.call(['grep', 'pattern', 'file'],
                     stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)
if rc == 0: # found
   ...
elif rc == 1: # not found
   ...
elif rc > 1: # error
   ...

You don't need shell=True to run the commands from your question.

Also check if your xampp is installed in the main directory like C or D or E and not in or within a folder of that directory? i.e. ( "D:/Xampp" or is it "D:/something/Xampp") if its not in the main path of the directory, it will show this error.

copy your xampp directory from "D:\Something\Xampp" to "D:"
So it becomes like this "D:\Xampp" and the issue will be resolved.

Close the modal box using javascript

$('#product-options').modal('hide');

Open the modal box using javascript

$('#product-options').modal('show');

Toggle the modal box using javascript

$('#myModal').modal('toggle');

Means close the modal if it's open and vice versa.

Since the column is of type VARCHAR, you should convert the input parameter to a string rather than converting the column value to a number:

select * from exception where exception_value = to_char(105);

To put the strings "l" and "vv" on separate lines in the code alone:

$xml = "l";
$xml .= "vv"
echo $xml;

In this instance you're saying to append .= the string to the end of the previous version of that string variable. Remember that = is only an assignment operator so in your original code you're assigning the variable a new string value.

To put the strings "l" and "vv" on separate lines in the echo alone:

$xml = "l\nvv"
echo $xml;

You don't need multiple strings in this instance, as the new line character \n will take care of that for you.

To put the strings "l" and "vv" on separate lines in code and when echoing:

$xml = "l";
$xml .= "\nvv"
echo $xml;

You probably have a forward declaration of the class, but haven't included the header:

#include <sstream>

//...
QString Stats_Manager::convertInt(int num)
{
    std::stringstream ss;   // <-- also note namespace qualification
    ss << num;
    return ss.str();
}

Since you haven't posted any code, it's difficult to know exactly which problems you're encountering. However, the blog post you link to does seem to work pretty decently... aside from the extra comma in each call to CCCrypt() which caused compile errors.

A later comment on that post includes this adapted code, which works for me, and seems a bit more straightforward. If you include their code for the NSData category, you can write something like this: (Note: The printf() calls are only for demonstrating the state of the data at various points — in a real application, it wouldn't make sense to print such values.)

int main (int argc, const char * argv[]) {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    NSString *key = @"my password";
    NSString *secret = @"text to encrypt";

    NSData *plain = [secret dataUsingEncoding:NSUTF8StringEncoding];
    NSData *cipher = [plain AES256EncryptWithKey:key];
    printf("%s\n", [[cipher description] UTF8String]);

    plain = [cipher AES256DecryptWithKey:key];
    printf("%s\n", [[plain description] UTF8String]);
    printf("%s\n", [[[NSString alloc] initWithData:plain encoding:NSUTF8StringEncoding] UTF8String]);

    [pool drain];
    return 0;
}

Given this code, and the fact that encrypted data will not always translate nicely into an NSString, it may be more convenient to write two methods that wrap the functionality you need, in forward and reverse...

- (NSData*) encryptString:(NSString*)plaintext withKey:(NSString*)key {
    return [[plaintext dataUsingEncoding:NSUTF8StringEncoding] AES256EncryptWithKey:key];
}

- (NSString*) decryptData:(NSData*)ciphertext withKey:(NSString*)key {
    return [[[NSString alloc] initWithData:[ciphertext AES256DecryptWithKey:key]
                                  encoding:NSUTF8StringEncoding] autorelease];
}

This definitely works on Snow Leopard, and @Boz reports that CommonCrypto is part of the Core OS on the iPhone. Both 10.4 and 10.5 have /usr/include/CommonCrypto, although 10.5 has a man page for CCCryptor.3cc and 10.4 doesn't, so YMMV.

EDIT: See this follow-up question on using Base64 encoding for representing encrypted data bytes as a string (if desired) using safe, lossless conversions.

Use Libre Office API Here is an example

libreoffice --headless --convert-to html docx-file-path --outdir html-dir-path

After your databind:

drpList.Items.Insert(0, new ListItem(String.Empty, String.Empty));
drpList.SelectedIndex = 0;

using position:fixed alone is just fine when you don't have a header or logo at the top of your page. This solution will take into account the how far the window has scrolled, and moves the div when you scrolled past your header. It will then lock it back into place when you get to the top again.

if($(window).scrollTop() > Height_of_Header){
    //begin to scroll
    $("#div").css("position","fixed");
    $("#div").css("top",0);
}
else{
    //lock it back into place
    $("#div").css("position","relative");
}

To perfectly forward without chopping the absoluteURI of the request and the Host in the header:

server {
    listen 35005;

    location / {
        rewrite            ^(.*)$   "://$http_host$uri$is_args$args";
        rewrite            ^(.*)$   "http$uri$is_args$args" break;
        proxy_set_header   Host     $host;

        proxy_pass         https://deploy.org.local:35005;
    }
}

Found here: https://opensysnotes.wordpress.com/2016/11/17/nginx-proxy_pass-with-absolute-url/

Adding dependencies didn't fix the issue at my end.

The issue was happening at my end because of "additional" fields that are part of the "@Entity" class and don't exist in the database.

I removed the additional fields from the @Entity class and it worked.

Seems to be a typo error in that package of gcc. The solution:

mv /usr/include/c++/4.x/i486-linux-gnu /usr/include/c++/4.x/i686-linux-gnu/64

If you want to scroll entire page to the bottom:

var scrollingElement = (document.scrollingElement || document.body);
scrollingElement.scrollTop = scrollingElement.scrollHeight;

See the sample on JSFiddle

If you want to scroll an element to the bottom:

function gotoBottom(id){
   var element = document.getElementById(id);
   element.scrollTop = element.scrollHeight - element.clientHeight;
}

And that's how it works:

Ref: scrollTop, scrollHeight, clientHeight

UPDATE: Latest versions of Chrome (61+) and Firefox does not support scrolling of body, see: https://dev.opera.com/articles/fixing-the-scrolltop-bug/

Now you can also use Talentsoft.Moq.SetupAsync package https://github.com/TalentSoft/Moq.SetupAsync

Which on the base on the answers found here and ideas proposed to Moq but still not yet implemented here: https://github.com/moq/moq4/issues/384, greatly simplify setup of async methods

Few examples found in previous responses done with SetupAsync extension:

mock.SetupAsync(arg=>arg.DoSomethingAsync());
mock.SetupAsync(arg=>arg.DoSomethingAsync()).Callback(() => { <my code here> });
mock.SetupAsync(arg=>arg.DoSomethingAsync()).Throws(new InvalidOperationException());

You can also try like this:

let array1 = [{_x000D_
    "description": "THURSDAY",_x000D_
    "count": "1",_x000D_
    "date": "2019-12-05"_x000D_
},_x000D_
{_x000D_
    "description": "WEDNESDAY",_x000D_
    "count": "0",_x000D_
    "date": "2019-12-04"_x000D_
}]_x000D_
let res = array1.map((value, index) => {_x000D_
    return { [value.description]: { count: value.count, date: value.date } }_x000D_
})_x000D_
console.log(res);

Use the ternary operator

direction == 1 ? dosomething () : dosomethingelse ();

I have created some simple function you can use to convert time to any timezone :

function convertTimeToLocal($datetime,$timezone='Europe/Dublin') {
        $given = new DateTime($datetime, new DateTimeZone("UTC"));
        $given->setTimezone(new DateTimeZone($timezone));
        $output = $given->format("Y-m-d"); //can change as per your requirement
        return $output;
}

hi this is my suggestion

 .......
var t = Task.Run(async () => await Task.Delay(TimeSpan.FromSeconds(Consts.FiveHundred)).ConfigureAwait(false));
                //just to wait task is done
                t.Wait();

keep in mind put the "wait" otherwise the Delay run without affect application

More stable approach:

<form onsubmit="foo($("#formValueId").val());return false;">
<input type="text" id="formValueId"/>
<input type="submit" value="Text on the button"/>
</form>

The return false; is to prevent actual form submit (assuming you want that).

When you choose any value from spinner, then you get selected value,

interested.getSelectedItem().toString();

The alert() dialog is not rendered in HTML, and thus the HTML you have embedded is meaningless.

You'd need to use a custom modal to achieve that.

For static resources right caching would be to use query parameters with value of each deployment or file version. This will have effect of clearing cache after each deployment.

/Content/css/Site.css?version={FileVersionNumber}

Here is ASP.NET MVC example.

<link href="@Url.Content("~/Content/Css/Reset.css")[email protected]().Assembly.GetName().Version" rel="stylesheet" type="text/css" />

Don't forget to update assembly version.

You would use the focus and blur events of the window:

var interval_id;
$(window).focus(function() {
    if (!interval_id)
        interval_id = setInterval(hard_work, 1000);
});

$(window).blur(function() {
    clearInterval(interval_id);
    interval_id = 0;
});

To Answer the Commented Issue of "Double Fire" and stay within jQuery ease of use:

$(window).on("blur focus", function(e) {
    var prevType = $(this).data("prevType");

    if (prevType != e.type) {   //  reduce double fire issues
        switch (e.type) {
            case "blur":
                // do work
                break;
            case "focus":
                // do work
                break;
        }
    }

    $(this).data("prevType", e.type);
})

In case someone is using git svn, I had the same problem but could not remove the file since it was not there!. After checking permissions, touching the file and deleting it, and I don't remember what else, this did the trick:

• checkout the master branch.
• git svn rebase (on master)
• checkout the branch you were working on
• git svn rebase

David's answer is correct, but if it's still a little abstract, here are two examples:

1. You might want to zero all freed pointers to catch memory problems earlier. C-style you'd do:

   void freeAndZero(void** ptr)
   {
       free(*ptr);
       *ptr = 0;
   }
   
   void* ptr = malloc(...);
   
   ...
   
   freeAndZero(&ptr);
   

   In C++ to do the same, you might do:

   template<class T> void freeAndZero(T* &ptr)
   {
       delete ptr;
       ptr = 0;
   }
   
   int* ptr = new int;
   
   ...
   
   freeAndZero(ptr);
   

2. When dealing with linked-lists - often simply represented as pointers to a next node:

   struct Node
   {
       value_t value;
       Node* next;
   };
   

   In this case, when you insert to the empty list you necessarily must change the incoming pointer because the result is not the NULL pointer anymore. This is a case where you modify an external pointer from a function, so it would have a reference to pointer in its signature:

   void insert(Node* &list)
   {
       ...
       if(!list) list = new Node(...);
       ...
   }
   

There's an example in this question.

In java 8 for none string array and none primitive object (Long, Integer, ...)

List<Long> ids = Arrays.asList(1l, 2l,3l);
ids.stream().map(String::valueOf).collect(Collectors.joining(","))))

In java 8 for specific field of an objets array (example a car with 2 fields color and speed)

List<Car> cars= Cars.asList(car1, cars2,car3);
    cars.stream().map(Car::getColor).collect(Collectors.joining(","))))

Combine map with valueOf for none String field of an array of objects

Even though you didn't provide enough information to answer this question properly, your best shots are SSH tunnels (or reverse SSH tunnels).

You only need one SSH server on your internal or remote network to provide access to your local machine.

You can use PUTTY (it has a GUI) on Windows to create your tunnel.

What are the situations where "yield from" is useful?

Every situation where you have a loop like this:

for x in subgenerator:
  yield x

As the PEP describes, this is a rather naive attempt at using the subgenerator, it's missing several aspects, especially the proper handling of the .throw()/.send()/.close() mechanisms introduced by PEP 342. To do this properly, rather complicated code is necessary.

What is the classic use case?

Consider that you want to extract information from a recursive data structure. Let's say we want to get all leaf nodes in a tree:

def traverse_tree(node):
  if not node.children:
    yield node
  for child in node.children:
    yield from traverse_tree(child)

Even more important is the fact that until the yield from, there was no simple method of refactoring the generator code. Suppose you have a (senseless) generator like this:

def get_list_values(lst):
  for item in lst:
    yield int(item)
  for item in lst:
    yield str(item)
  for item in lst:
    yield float(item)

Now you decide to factor out these loops into separate generators. Without yield from, this is ugly, up to the point where you will think twice whether you actually want to do it. With yield from, it's actually nice to look at:

def get_list_values(lst):
  for sub in [get_list_values_as_int, 
              get_list_values_as_str, 
              get_list_values_as_float]:
    yield from sub(lst)

Why is it compared to micro-threads?

I think what this section in the PEP is talking about is that every generator does have its own isolated execution context. Together with the fact that execution is switched between the generator-iterator and the caller using yield and __next__(), respectively, this is similar to threads, where the operating system switches the executing thread from time to time, along with the execution context (stack, registers, ...).

The effect of this is also comparable: Both the generator-iterator and the caller progress in their execution state at the same time, their executions are interleaved. For example, if the generator does some kind of computation and the caller prints out the results, you'll see the results as soon as they're available. This is a form of concurrency.

That analogy isn't anything specific to yield from, though - it's rather a general property of generators in Python.

Its possible, but not directly.

In short, go to the search, use your regex, check "mark line" and click "Find all". It results in bookmarks for all those lines.

In the search menu there is a point "delete bookmarked lines" voila.

I found the answer here (the correct answer is the second one, not the accepted!): How to delete specific lines on Notepad++?

Use this regular expression if you don't want to start with zero:

^[1-9]([0-9]{1,45}$)

If you don't mind starting with zero, use:

^[0-9]{1,45}$

Don't believe all those who try to mislead you.

In your request, just add:

ca: [fs.readFileSync([certificate path], {encoding: 'utf-8'})]

If you turn on unauthorized certificates, you will not be protected at all (exposed to MITM for not validating identity), and working without SSL won't be a big difference. The solution is to specify the CA certificate that you expect as shown in the next snippet. Make sure that the common name of the certificate is identical to the address you called in the request(As specified in the host):

What you will get then is:

var req = https.request({ 
      host: '192.168.1.1', 
      port: 443,
      path: '/',
      ca: [fs.readFileSync([certificate path], {encoding: 'utf-8'})],
      method: 'GET',
      rejectUnauthorized: true,
      requestCert: true,
      agent: false
    },

Assuming you are talking about JavaScript in an HTML document.

You can't do this directly since, as far as the JSP is concerned, it is outputting text, and as far as the page is concerned, it is just getting an HTML document.

You have to generate JavaScript code to instantiate the variable, taking care to escape any characters with special meaning in JS. If you just dump the data (as proposed by some other answers) you will find it falling over when the data contains new lines, quote characters and so on.

The simplest way to do this is to use a JSON library (there are a bunch listed at the bottom of http://json.org/ ) and then have the JSP output:

<script type="text/javascript">
    var myObject = <%= the string output by the JSON library %>;
</script>

This will give you an object that you can access like:

myObject.someProperty

in the JS.

@Will, git immersion is a really nice and simple git tutorial. it will show you how to undo changes for the following cases: unstaged, staged and committed. labs 14-18

Use curly braces around the variable name:

`tail -1 ${filepath}_newstap.sh`

Justin's answer is the way to go, but also as an FYI you can use the chr() function with the ascii value of the character you want to insert. For this example it would be:

INSERT INTO STUDENT(name, class_id) VALUES ('Samantha', 'Java_22 '||chr(38)||' Oracle_14'); 

The DBA views are restricted. So you won't be able to query them unless you're connected as a DBA or similarly privileged user.

The ALL views show you the information you're allowed to see. Normally that would be jobs you've submitted, unless you have additional privileges.

The privileges you need are defined in the Admin Guide. Find out more.

So, either you need a DBA account or you need to chat with your DBA team about getting access to the information you need.

None has worked for me. But his one did.

Since the Bootstrap 4 .row class is now display:flex you can simply use the new align-self-center flexbox utility on any column to vertically center it:

<div class="row">
   <div class="col-6 align-self-center">
      <div class="card card-block">
      Center
      </div>
   </div>
   <div class="col-6">
      <div class="card card-inverse card-danger">
      Taller
      </div>
   </div>
</div>

I learned about it from https://medium.com/wdstack/bootstrap-4-vertical-center-1211448a2eff

But if you are using Plesk, change your settings in :

/usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/config.default.php

Change $cfg['ExecTimeLimit'] = 300; to $cfg['ExecTimeLimit'] = 0;

And restart with Plesk UI or use:

/etc/init.d/psa restart and /etc/init.d/httpd restart

Try this:

Function.prototype.extends = function(parent) {
  this.prototype = Object.create(parent.prototype);
};

Monkey.extends(Monster);
function Monkey() {
  Monster.apply(this, arguments); // call super
}

Edit: I put a quick demo here http://jsbin.com/anekew/1/edit. Note that extends is a reserved word in JS and you may get warnings when linting your code, you can simply name it inherits, that's what I usually do.

With this helper in place and using an object props as only parameter, inheritance in JS becomes a bit simpler:

Function.prototype.inherits = function(parent) {
  this.prototype = Object.create(parent.prototype);
};

function Monster(props) {
  this.health = props.health || 100;
}

Monster.prototype = {
  growl: function() {
    return 'Grrrrr';
  }
};

Monkey.inherits(Monster);
function Monkey() {
  Monster.apply(this, arguments);
}

var monkey = new Monkey({ health: 200 });

console.log(monkey.health); //=> 200
console.log(monkey.growl()); //=> "Grrrr"

gzip > stdin.gz perhaps? Otherwise, you need to flesh out your question.

An example based on Chuck's answer:

myIntToStr :: Int -> String
myIntToStr x
    | x < 3     = show x ++ " is less than three"
    | otherwise = "normal"

Note that without the show the third line will not compile.

So basically you want to find a file in mounted filesystem (not necessarily in PATH directories only) and check if it is executable. This translates to following plan:

• enumerate all files in locally mounted filesystems
• match results with name pattern
• for each file found check if it is executable

I'd say, doing this in a portable way will require lots of computing power and time. Is it really what you need?

Use two minipages.

\begin{minipage}[position]{width}
  text
 \end{minipage}

Try to this one

$dataProvider = new ActiveDataProvider([
    'query' => $query,
]);

$sort = $dataProvider->getSort();

$sort->defaultOrder = ['id' => SORT_ASC];

$dataProvider->setSort($sort);

Can you use boost?

samm$ cat split.cc
#include <boost/algorithm/string/classification.hpp>
#include <boost/algorithm/string/split.hpp>

#include <boost/foreach.hpp>

#include <iostream>
#include <string>
#include <vector>

int
main()
{
    std::string split_me( "hello world  how are   you" );

    typedef std::vector<std::string> Tokens;
    Tokens tokens;
    boost::split( tokens, split_me, boost::is_any_of(" ") );

    std::cout << tokens.size() << " tokens" << std::endl;
    BOOST_FOREACH( const std::string& i, tokens ) {
        std::cout << "'" << i << "'" << std::endl;
    }
}

sample execution:

samm$ ./a.out

Make sure that the actual .vim file is in ~/.vim/plugin/

$ date +%s.%N

where (GNU Coreutils 8.24 Date manual)

• +%s, seconds since 1970-01-01 00:00:00 UTC
• +%N, nanoseconds (000000000..999999999) since epoch

Example output now 1454000043.704350695. I noticed that BSD manual of date did not include precise explanation about the flag +%s.

I don't suggest you just hidding the stricts errors on your project. Intead, you should turn your method to static or try to creat a new instance of the object:

$var = new YourClass();
$var->method();

You can also use the new way to do the same since PHP 5.4:

(new YourClass)->method();

I hope it helps you!

You need to add gecko driver if you are using firefox v50 and above.

Use the following sample code :

File pathToBinary = new File("C:\\Program Files\\Mozilla Firefox\\firefox.exe");
FirefoxBinary ffBinary = new FirefoxBinary(pathToBinary);
FirefoxProfile firefoxProfile = new FirefoxProfile();
System.setProperty("webdriver.gecko.driver","C:\\Users\\Downloads\\selenium-java-3.0.1\\geckodriver.exe");       
WebDriver driver = new FirefoxDriver(ffBinary,firefoxProfile);

I am working with 35000 lines of data.

$f=fopen("veri1.txt","r");
$i=0;
while(!feof($f)){
    $i++;
    $line=mb_convert_encoding(fgets($f), 'HTML-ENTITIES', "UTF-8");
    echo $line;
}

This code convert my strange characters into normal.

One that worked for me was:

.+(\\.+)$

Try it online!

Explanation:

.+     - any character except newline
(      - create a group
 \\.+   - match a backslash, and any characters after it
)      - end group
$      - this all has to happen at the end of the string

$cn.Open();
$cmd.CommandTimeout = 0
$cmd.ExecuteNonQuery()
$cn.Close();

The "encoded_c" mentioned in the @smehmood's Vigenere cipher answer should be "key_c".

Here are working encode/decode functions.

def encode(key, clear):
    enc = []
    for i in range(len(clear)):
        key_c = key[i % len(key)]
        enc_c = chr((ord(clear[i]) + ord(key_c)) % 256)
        enc.append(enc_c)
    return base64.urlsafe_b64encode("".join(enc))

def decode(key, enc):
    dec = []
    enc = base64.urlsafe_b64decode(enc)
    for i in range(len(enc)):
        key_c = key[i % len(key)]
        dec_c = chr((256 + ord(enc[i]) - ord(key_c)) % 256)
        dec.append(dec_c)
    return "".join(dec)

You can simply add "default none" to your variable as the form below mentioned:

{{ your_var | default('NONE', boolean=true) }}

In the following line.

temp.Response = db.Responses.Where(y => y.ResponseId.Equals(item.ResponseId)).First();

You are calling First but the collection returned from db.Responses.Where is empty.

Here is obscure solution: define macro function:

In my scenario the build service was not using the same user account that I imported the key with using sn.exe.

After changing the account to my administrator account, everything is working just fine.

You can use Line height a big as height of the div. But for me best solution is this --> position:relative; top:50%; transform:translate(0,50%);

Mongoose uses the mongodb-native driver, which uses the custom ObjectID type. You can compare ObjectIDs with the .equals() method. With your example, results.userId.equals(AnotherMongoDocument._id). The ObjectID type also has a toString() method, if you wish to store a stringified version of the ObjectID in JSON format, or a cookie.

If you use ObjectID = require("mongodb").ObjectID (requires the mongodb-native library) you can check if results.userId is a valid identifier with results.userId instanceof ObjectID.

Etc.

Use <code> for inline code that can wrap and <pre><code> for block code that must not wrap. <samp> is for sample output, so I would avoid using it to represent sample code (which the reader is to input). This is what Stack Overflow does.

(Better yet, if you want easy to maintain, let the users edit the articles as Markdown, then they don’t have to remember to use <pre><code>.)

HTML5 agrees with this in “the pre element”:

The pre element represents a block of preformatted text, in which structure is represented by typographic conventions rather than by elements.

Some examples of cases where the pre element could be used:

• Including fragments of computer code, with structure indicated according to the conventions of that language.

[…]

To represent a block of computer code, the pre element can be used with a code element; to represent a block of computer output the pre element can be used with a samp element. Similarly, the kbd element can be used within a pre element to indicate text that the user is to enter.

In the following snippet, a sample of computer code is presented.

<p>This is the <code>Panel</code> constructor:</p>
<pre><code>function Panel(element, canClose, closeHandler) {
      this.element = element;
      this.canClose = canClose;
      this.closeHandler = function () { if (closeHandler) closeHandler() };
    }</code></pre>

jQuery does not have an option for this, nor should it have one. This is perfectly valid javascript and there is no reason for jQuery to provide wrapper functions for this.

jQuery is just a library on top of javascript, even if you use jQuery you can still use normal javascript.

Btw window.location is not a function but a property which you should set like this:

window.location = url;

XSD:
XSD (XML Schema Definition) specifies how to formally describe the elements in an Extensible Markup Language (XML) document.
Xml:
XML was designed to describe data.It is independent from software as well as hardware.
It enhances the following things.
-Data sharing.
-Platform independent.
-Increasing the availability of Data.

Differences:

1. XSD is based and written on XML.

2. XSD defines elements and structures that can appear in the document, while XML does not.

3. XSD ensures that the data is properly interpreted, while XML does not.

4. An XSD document is validated as XML, but the opposite may not always be true.

5. XSD is better at catching errors than XML.

An XSD defines elements that can be used in the documents, relating to the actual data with which it is to be encoded.
for eg:
A date that is expressed as 1/12/2010 can either mean January 12 or December 1st. Declaring a date data type in an XSD document, ensures that it follows the format dictated by XSD.

The above answers regarding @JsonProperty and CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES are 100% accurate, although some people (like me) might be trying to do this inside a Spring MVC application with code-based configuration. Here's sample code (that I have inside Beans.java) to achieve the desired effect:

@Bean
public ObjectMapper jacksonObjectMapper() {
    return new ObjectMapper().setPropertyNamingStrategy(
            PropertyNamingStrategy.CAMEL_CASE_TO_LOWER_CASE_WITH_UNDERSCORES);
}

I got it to work by Enabling 32 bit applications in the Application Pool advanced settings. Right click on the application pool and choose advanced settings - enable 32 bit applications. This may help someone out there.

The basic questions that differentiate implementations of "CopyStream" are:

• size of the reading buffer
• size of the writes
• Can we use more than one thread (writing while we are reading).

The answers to these questions result in vastly different implementations of CopyStream and are dependent on what kind of streams you have and what you are trying to optimize. The "best" implementation would even need to know what specific hardware the streams were reading and writing to.

Well, data.str().c_str() yields a char const* but your function Printfunc() wants to have char*s. Based on the name, it doesn't change the arguments but merely prints them and/or uses them to name a file, in which case you should probably fix your declaration to be

void Printfunc(int a, char const* loc, char const* stream)

The alternative might be to turn the char const* into a char* but fixing the declaration is preferable:

Printfunc(num, addr, const_cast<char*>(data.str().c_str()));

Thank you. I believe that a complete example could be good for anyone else who have the same issue:

import pandas as pd
import numpy as np

path = r"C:\Users\fedel\Desktop\excelData\PhD_data.xlsx"

x1 = np.random.randn(100, 2)
df1 = pd.DataFrame(x1)

x2 = np.random.randn(100, 2)
df2 = pd.DataFrame(x2)

writer = pd.ExcelWriter(path, engine = 'xlsxwriter')
df1.to_excel(writer, sheet_name = 'x1')
df2.to_excel(writer, sheet_name = 'x2')
writer.save()
writer.close()

Here I generate an excel file, from my understanding it does not really matter whether it is generated via the "xslxwriter" or the "openpyxl" engine.

When I want to write without loosing the original data then

import pandas as pd
import numpy as np
from openpyxl import load_workbook

path = r"C:\Users\fedel\Desktop\excelData\PhD_data.xlsx"

book = load_workbook(path)
writer = pd.ExcelWriter(path, engine = 'openpyxl')
writer.book = book

x3 = np.random.randn(100, 2)
df3 = pd.DataFrame(x3)

x4 = np.random.randn(100, 2)
df4 = pd.DataFrame(x4)

df3.to_excel(writer, sheet_name = 'x3')
df4.to_excel(writer, sheet_name = 'x4')
writer.save()
writer.close()

this code do the job!

You can use concat:

In [11]: pd.concat([df1['c'], df2['c']], axis=1, keys=['df1', 'df2'])
Out[11]: 
                 df1       df2
2014-01-01       NaN -0.978535
2014-01-02 -0.106510 -0.519239
2014-01-03 -0.846100 -0.313153
2014-01-04 -0.014253 -1.040702
2014-01-05  0.315156 -0.329967
2014-01-06 -0.510577 -0.940901
2014-01-07       NaN -0.024608
2014-01-08       NaN -1.791899

[8 rows x 2 columns]

The axis argument determines the way the DataFrames are stacked:

df1 = pd.DataFrame([1, 2, 3])
df2 = pd.DataFrame(['a', 'b', 'c'])

pd.concat([df1, df2], axis=0)
   0
0  1
1  2
2  3
0  a
1  b
2  c

pd.concat([df1, df2], axis=1)

   0  0
0  1  a
1  2  b
2  3  c

Piece of cake.

Use 960Grids Go to the automatic layout builder and make a two column, fluid design. Build a left column to the width of grids that works....this is the only challenge using grids and it's very easy once you read a tutorial. In a nutshell, each column in a grid is a certain width, and you set the amount of columns you want to use. To get a column that's exactly a certain width, you have to adjust your math so that your column width is exact. Not too tough.

No chance of wrapping because others have already fought that battle for you. Compatibility back as far as you likely will ever need to go. Quick and easy....Now, download, customize and deploy.

Voila. Grids FTW.

None of these worked for me.

My class libraries were definitely all referencing both System.Core and Microsoft.CSharp. Web Application was 4.0 and couldn't upgrade to 4.5 due to support issues.

I was encountering the error compiling a razor template using the Razor Engine, and only encountering it intermittently, like after web application has been restarted.

The solution that worked for me was manually loading the assembly then reattempting the same operation...

        bool retry = true;
        while (retry)
        {
            try
            {
                string textTemplate = File.ReadAllText(templatePath);
                Razor.CompileWithAnonymous(textTemplate, templateFileName);
                retry = false;
            }
            catch (TemplateCompilationException ex)
            {
                LogTemplateException(templatePath, ex);
                retry = false;

                if (ex.Errors.Any(e  => e.ErrorNumber == "CS1969"))
                {
                    try
                    {
                        _logger.InfoFormat("Attempting to manually load the Microsoft.CSharp.RuntimeBinder.Binder");
                        Assembly csharp = Assembly.Load("Microsoft.CSharp, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a");
                        Type type = csharp.GetType("Microsoft.CSharp.RuntimeBinder.Binder");
                        retry = true;
                    }
                    catch(Exception exLoad)
                    {
                        _logger.Error("Failed to manually load runtime binder", exLoad);
                    }
                }

                if (!retry)
                    throw;
            }
        }

Hopefully this might help someone else out there.

Probably the simplest way to do this is ->

import os
os.chdir("X:\Enter location of .bat file")
os.startfile("ask.bat")

A ListView is a specialized ListBox (that is, it inherits from ListBox). It allows you to specify different views rather than a straight list. You can either roll your own view, or use GridView (think explorer-like "details view"). It's basically the multi-column listbox, the cousin of windows form's listview.

If you don't need the additional capabilities of ListView, you can certainly use ListBox if you're simply showing a list of items (Even if the template is complex).

You can index and use a negative sign to drop the 3rd column:

data[,-3]

Or you can list only the first 2 columns:

data[,c("c1", "c2")]
data[,1:2]

Don't forget the comma and referencing data frames works like this: data[row,column]

I also found the apache commons IOUtils class , so :

InputStreamReader isr = new InputStreamReader(IOUtils.toInputStream(myString));

In my case, it was related to the node version.

My project was using 12.18.3 but I was on 14.5.0

So npm rebuild node-sass didn't solve the issue on the wrong node version(14.5.0).

I switched to the correct version(12.18.3) so it worked.

Some browsers have a security feature that prevents JavaScript from knowing your file's local full path. It makes sense - as a client, you don't want the server to know your local machine's filesystem. It would be nice if all browsers did this.

I'm surprised no one has mentioned filter_input, so here is Alix Axel's answer condensed to one-line:

function get_ip_address(&$keys = ['HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'HTTP_CLIENT_IP', 'REMOTE_ADDR'])
{
    return empty($keys) || ($ip = filter_input(INPUT_SERVER, array_pop($keys), FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE))? $ip : get_ip_address($keys);
}

Very easy to use select option submit

<select name="sortby" onchange="this.form.submit()">
       <option value="">Featured</option>
       <option value="asc" >Price: Low to High</option>
        <option value="desc">Price: High to Low</option>                                   
</select>

May be you can find answer here? Equivalent of double-clickable .sh and .bat on Mac?

Usually you can create bash script for Mac OS, where you put similar commands as in batch file. For your case create bash file and put same command, but change back-slashes with regular ones.

Your file will look something like:

#! /bin/bash
java -cp  ".;./supportlibraries/Framework_Core.jar;./supportlibraries/Framework_DataTable.jar;./supportlibraries/Framework_Reporting.jar;./supportlibraries/Framework_Utilities.jar;./supportlibraries/poi-3.8-20120326.jar;PATH_TO_YOUR_SELENIUM_SERVER_FOLDER/selenium-server-standalone-2.19.0.jar" allocator.testTrack

Change folders in path above to relevant one.

Then make this script executable: open terminal and navigate to folder with your script. Then change read-write-execute rights for this file running command:

chmod 755 scriptname.sh

Then you can run it like any other regular script: ./scriptname.sh

or you can run it passing file to bash:

bash scriptname.sh

There is a better solution to this answer that is more Angular based.

1. Save your string in a variable in the .ts file

   MyStrings = ["one","two","three"]

2. In the html file use *ngFor.

   <div class="one" *ngFor="let string of MyStrings; let i = index"> <div class="two">{{string}}</div> </div>

3. if you want to dynamically insert the div element, just push more strings into the MyStrings array

   myFunction(nextString){ this.MyString.push(nextString) }

this way every time you click the button containing the myFunction(nextString) you effectively add another class="two" div which acts the same way as inserting it into the DOM with pure javascript.

There isn’t really an ideal conversion, but I would like to supply a couple of options.

java.time

First, you should use LocalDate from java.time, the modern Java date and time API, for parsing and holding your date. Avoid Date and SimpleDateFormat since they have design problems and also are long outdated. The latter in particular is notoriously troublesome.

    DateTimeFormatter originalDateFormatter = DateTimeFormatter.ofPattern("dd/MM/uuuu");

    String dateString = "13/06/1983";
    LocalDate date = LocalDate.parse(dateString, originalDateFormatter);
    System.out.println(date);

The output is:

1983-06-13

Do you need to go any further? LocalDate.toString() produces the format you asked about.

Format and parse

Assuming that you do require an XMLGregorianCalendar the first and easy option for converting is:

    XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(date.toString());
    System.out.println(xmlDate);

1983-06-13

Formatting to a string and parsing it back feels like a waste to me, but as I said, it’s easy and I don’t think that there are any surprises about the result being as expected.

Pass year, month and day of month individually

    XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
            .newXMLGregorianCalendarDate(date.getYear(), date.getMonthValue(),
                    date.getDayOfMonth(), DatatypeConstants.FIELD_UNDEFINED);

The result is the same as before. We need to make explicit that we don’t want a time zone offset (this is what DatatypeConstants.FIELD_UNDEFINED specifies). In case someone is wondering, both LocalDate and XMLGregorianCalendar number months the way humans do, so there is no adding or subtracting 1.

Convert through GregorianCalendar

I only show you this option because I somehow consider it the official way: convert LocalDate to ZonedDateTime, then to GregorianCalendar and finally to XMLGregorianCalendar.

    ZonedDateTime dateTime = date.atStartOfDay(ZoneOffset.UTC);
    GregorianCalendar gregCal = GregorianCalendar.from(dateTime);
    XMLGregorianCalendar xmlDate = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(gregCal);
    xmlDate.setTime(DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED,
            DatatypeConstants.FIELD_UNDEFINED, DatatypeConstants.FIELD_UNDEFINED);
    xmlDate.setTimezone(DatatypeConstants.FIELD_UNDEFINED);

I like the conversion itself since we neither need to use strings nor need to pass individual fields (with care to do it in the right order). What I don’t like is that we have to pass a time of day and a time zone offset and then wipe out those fields manually afterwards.

Things are going better, right now you can use SVG files.

        marker = new google.maps.Marker({
            position: {lat: 36.720426, lng: -4.412573},
            map: map,
            draggable: true,
            icon: "img/tree.svg"
        });

It's been said elaborately, just as "the short answer":

• static variable (class)
  lifetime = program runtime (1)
  visibility = determined by access modifiers (private/protected/public)

• static variable (global scope)
  lifetime = program runtime (1)
  visibility = the compilation unit it is instantiated in (2)

• heap variable
  lifetime = defined by you (new to delete)
  visibility = defined by you (whatever you assign the pointer to)

• stack variable
  visibility = from declaration until scope is exited
  lifetime = from declaration until declaring scope is exited

(1) more exactly: from initialization until deinitialization of the compilation unit (i.e. C / C++ file). Order of initialization of compilation units is not defined by the standard.

(2) Beware: if you instantiate a static variable in a header, each compilation unit gets its own copy.

Majority of the solutions above have a high run time complexity.

Here is the solution that uses reduce and can do the job in O(n) time.

Array.prototype.unique = Array.prototype.unique || function() {_x000D_
        var arr = [];_x000D_
 this.reduce(function (hash, num) {_x000D_
  if(typeof hash[num] === 'undefined') {_x000D_
   hash[num] = 1; _x000D_
   arr.push(num);_x000D_
  }_x000D_
  return hash;_x000D_
 }, {});_x000D_
 return arr;_x000D_
}_x000D_
    _x000D_
var myArr = [3,1,2,3,3,3];_x000D_
console.log(myArr.unique()); //[3,1,2];

Note:

This solution is not dependent on reduce. The idea is to create an object map and push unique ones into the array.

A much better solution to your problem would be to use Route which lets you specify the route on the method by annotation:

[RoutePrefix("api/VTRouting")]
public class VTRoutingController : ApiController
{
    [HttpPost]
    [Route("Route")]
    public MyResult Route(MyRequestTemplate routingRequestTemplate)
    {
        return null;
    }

    [HttpPost]
    [Route("TSPRoute")]
    public MyResult TSPRoute(MyRequestTemplate routingRequestTemplate)
    {
        return null;
    }
}

Update: newer versions should use php-sqlite3 package instead of php5-sqlite. So use this, if you are using a recent ubuntu version:

sudo apt-get install sqlite php-sqlite3

Original answer to question is here:

sudo apt-get install sqlite php5-sqlite
sudo /etc/init.d/apache2 restart

If your phpinfo() is not showing the pdo_sqlite line (in my case, on my Ubuntu Server), you just need to run the lines above and then you'll be good to go.

I've never used it but there is a JWT implementation on NuGet.

Package: https://nuget.org/packages/JWT

Source: https://github.com/johnsheehan/jwt

.NET 4.0 compatible: https://www.nuget.org/packages/jose-jwt/

You can also go here: https://jwt.io/ and click "libraries".

I recommend using the HTML <base> element:

<head>
    <base href="http://www.example.com/default/">
    <link rel="stylesheet" href="style.css" />
    <script src="script.js"></script>
</head>

In this example, the stylesheet is located in http://www.example.com/default/style.css, the script in http://www.example.com/default/script.js. The advantage of <base> over / is that it is more flexible. Your whole website can be located in a subdirectory of a domain, and you can easily alter the default directory of your website.

Try this.(IE8+)

//Define function
function removeJsonAttrs(json,attrs){
    return JSON.parse(JSON.stringify(json,function(k,v){
        return attrs.indexOf(k)!==-1 ? undefined: v;
}));}
//use object
var countries = {};
countries.results = [
    {id:'AF',name:'Afghanistan'},
    {id:'AL',name:'Albania'},
    {id:'DZ',name:'Algeria'}
];
countries = removeJsonAttrs(countries,["name"]);
//use array
var arr = [
    {id:'AF',name:'Afghanistan'},
    {id:'AL',name:'Albania'},
    {id:'DZ',name:'Algeria'}
];
arr = removeJsonAttrs(arr,["name"]);

The solution I've been using for a few years now:

@echo off
rem Refresh PATH from registry.
setlocal
set USR_PATH=
set SYS_PATH=
for /F "tokens=3* skip=2" %%P in ('%SystemRoot%\system32\reg.exe query "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /v PATH') do @set "SYS_PATH=%%P %%Q"
for /F "tokens=3* skip=2" %%P in ('%SystemRoot%\system32\reg.exe query "HKCU\Environment" /v PATH') do @set "USR_PATH=%%P %%Q"
if "%SYS_PATH:~-1%"==" " set "SYS_PATH=%SYS_PATH:~0,-1%"
if "%USR_PATH:~-1%"==" " set "USR_PATH=%USR_PATH:~0,-1%"
endlocal & call set "PATH=%SYS_PATH%;%USR_PATH%"
goto :EOF

Edit: Woops, here's the updated version.

There are generally 2 levels of buffering-

1. Kernel buffer Cache (makes read/write faster)

2. Buffering in I/O library (reduces no. of system calls)

Let's take example of fprintf and write().

When you call fprintf(), it doesn't wirte directly to the file. It first goes to stdio buffer in the program's memory. From there it is written to the kernel buffer cache by using write system call. So one way to skip I/O buffer is directly using write(). Other ways are by using setbuff(stream,NULL). This sets the buffering mode to no buffering and data is directly written to kernel buffer. To forcefully make the data to be shifted to kernel buffer, we can use "\n", which in case of default buffering mode of 'line buffering', will flush I/O buffer. Or we can use fflush(FILE *stream).

Now we are in kernel buffer. Kernel(/OS) wants to minimise disk access time and hence it reads/writes only blocks of disk. So when a read() is issued, which is a system call and can be invoked directly or through fscanf(), kernel reads the disk block from disk and stores it in a buffer. After that data is copied from here to user space.

Similarly that fprintf() data recieved from I/O buffer is written to the disk by the kernel. This makes read() write() faster.

Now to force the kernel to initiate a write(), after which data transfer is controlled by hardware controllers, there are also some ways. We can use O_SYNC or similar flags during write calls. Or we could use other functions like fsync(),fdatasync(),sync() to make the kernel initiate writes as soon as data is available in the kernel buffer.

This is my favourite way of decoding HTML characters. The advantage of using this code is that tags are also preserved.

function decodeHtml(html) {
    var txt = document.createElement("textarea");
    txt.innerHTML = html;
    return txt.value;
}

Example: http://jsfiddle.net/k65s3/

Input:

Entity:&nbsp;Bad attempt at XSS:<script>alert('new\nline?')</script><br>

Output:

Entity: Bad attempt at XSS:<script>alert('new\nline?')</script><br>

You forgot to declare double as a return type

public double diameter()
{
    double d = radius * 2;
    return d;
}

you can do git reset --hard ORIG_HEAD

since "pull" or "merge" set ORIG_HEAD to be the current state before doing those actions.

Just type

document.querySelector('video').playbackRate = 1.25;

in JS console of your modern browser.

gene_name = no_headers.iloc[1:,[1]]

This creates a DataFrame because you passed a list of columns (single, but still a list). When you later do this:

gene_name[x]

you now have a Series object with a single value. You can't hash the Series.

The solution is to create Series from the start.

gene_type = no_headers.iloc[1:,0]
gene_name = no_headers.iloc[1:,1]
disease_name = no_headers.iloc[1:,2]

Also, where you have orph_dict[gene_name[x]] =+ 1, I'm guessing that's a typo and you really mean orph_dict[gene_name[x]] += 1 to increment the counter.

Are you specifically trying to rotate the links only? Because doing it on the LI tags seems to work fine.

According to Snook transforms require the elements affected be block. He's also got some code there to make this work for IE using filters, if you care to add it on(though there appears to be some limitation on values).

SUBSTRING ( MyColumn, 1 , 1 ) for the first character and SUBSTRING ( MyColumn, 1 , 2 ) for the first two.

I tested both requests-futures and grequests. Grequests is faster but brings monkey patching and additional problems with dependencies. requests-futures is several times slower than grequests. I decided to write my own and simply wrapped requests into ThreadPoolExecutor and it was almost as fast as grequests, but without external dependencies.

import requests
import concurrent.futures

def get_urls():
    return ["url1","url2"]

def load_url(url, timeout):
    return requests.get(url, timeout = timeout)

with concurrent.futures.ThreadPoolExecutor(max_workers=20) as executor:

    future_to_url = {executor.submit(load_url, url, 10): url for url in     get_urls()}
    for future in concurrent.futures.as_completed(future_to_url):
        url = future_to_url[future]
        try:
            data = future.result()
        except Exception as exc:
            resp_err = resp_err + 1
        else:
            resp_ok = resp_ok + 1

There have been previous answers that showed the trick. In essence:

• you must retain POSIXct types to take advantage of all the existing plotting functions

• if you want to 'overlay' several days worth on a single plot, highlighting the intra-daily variation, the best trick is too ...

• impose the same day (and month and even year if need be, which is not the case here)

which you can do by overriding the day-of-month and month components when in POSIXlt representation, or just by offsetting the 'delta' relative to 0:00:00 between the different days.

So with times and val as helpfully provided by you:

## impose month and day based on first obs
ntimes <- as.POSIXlt(times)    # convert to 'POSIX list type'
ntimes$mday <- ntimes[1]$mday  # and $mon if it differs too
ntimes <- as.POSIXct(ntimes)   # convert back

par(mfrow=c(2,1))
plot(times,val)   # old times
plot(ntimes,val)  # new times

yields this contrasting the original and modified time scales:

Little late... I had to respond. This is the simplest way.

Step by step. .padEnd - Guarentees the length of the string

"The padEnd() method pads the current string with a given string (repeated, if needed) so that the resulting string reaches a given length. The padding is applied from the end (right) of the current string. The source for this interactive example is stored in a GitHub repository." source: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…

.substring - limits to the length you need

If you choose to add ellipses, append them to the output.

I gave 4 examples of common JavaScript usages. I highly recommend using the String prototype with Overloading for legacy support. It makes it much easier to implement and change later.

For IE: window.close(); and self.close(); should work fine.

If you want just open the IE browser and type

javascript:self.close() and hit enter, it should ask you for a prompt.

Note: this method doesn't work for Chrome or Firefox.

Why does response.json return a promise?

Because you receive the response as soon as all headers have arrived. Calling .json() gets you another promise for the body of the http response that is yet to be loaded. See also Why is the response object from JavaScript fetch API a promise?.

Why do I get the value if I return the promise from the then handler?

Because that's how promises work. The ability to return promises from the callback and get them adopted is their most relevant feature, it makes them chainable without nesting.

You can use

fetch(url).then(response => 
    response.json().then(data => ({
        data: data,
        status: response.status
    })
).then(res => {
    console.log(res.status, res.data.title)
}));

or any other of the approaches to access previous promise results in a .then() chain to get the response status after having awaited the json body.

If what you need is UPDATE from SELECT statement you can do something like this:

UPDATE suppliers    
SET city = (SELECT customers.city FROM customers

WHERE customers.customer_name = suppliers.supplier_name)

Try this

var g = $('#<%=Label1.ClientID%>').text();

Another way, you can use a pass-through object to capture the last value and then do something with it:

List<Integer> list = new ArrayList<Integer>();
Integer lastValue = null;
for (Integer i : list) {
    // do stuff
    lastValue = i;
}
// do stuff with last value

The fastest way to check if a string contains another string is using indexOf:

if (code.indexOf('ST1') !== -1) {
    // string code has "ST1" in it
} else {
    // string code does not have "ST1" in it
}

You can use %x or %X or %p; all of them are correct.

• If you use %x, the address is given as lowercase, for example: a3bfbc4
• If you use %X, the address is given as uppercase, for example: A3BFBC4

Both of these are correct.

If you use %x or %X it's considering six positions for the address, and if you use %p it's considering eight positions for the address. For example:

Thanks for @bkurzius's answer and this update is for Charles 3.10+. (The reason is here)

1. Open Charles
2. Go to Proxy > SSL Proxy Settings...
3. Check “Enable SSL Proxying”
4. Select “Add location” and enter the host name and port (if needed)
5. Click ok and make sure the option is checked
6. Go to Help > SSL Proxying > Install Charles Root Certificate on a Mobile Device or Remote Browser..., and just follow the instruction. (use the Android's browser to download and install the certificate.)
7. In “Name the certificate” enter whatever you want
8. Click OK and you should get a message that the certificate was installed

From performance point of view if two lists contain number of elements that differ significantly, you can try such approach (using conditional operator ?:):

1.First you need to declare a converter:

Converter<string, int> del = delegate(string s) { return Int32.Parse(s); };

2.Then you use a conditional operator:

var r = data1.Count > data2.Count ?
 data2.ConvertAll<int>(del).Intersect(data1) :
 data1.Select(v => v.ToString()).Intersect(data2).ToList<string>().ConvertAll<int>(del);

You convert elements of shorter list to match the type of longer list. Imagine an execution speed if your first set contains 1000 elements and second only 10 (or opposite as it doesn't matter) ;-)

As you want to have a result as List, in a last line you convert the result (only result) back to int.

You can use jquery for this:

$('body').bind('copy paste',function(e) {
    e.preventDefault(); return false; 
});

Using jQuery bind() and specififying your desired eventTypes .

Eric Baker's comment tipped me off to the core idea that in order for a view to have its size be determined by the content placed within it, then the content placed within it must have an explicit relationship with the containing view in order to drive its height (or width) dynamically. "Add subview" does not create this relationship as you might assume. You have to choose which subview is going to drive the height and/or width of the container... most commonly whatever UI element you have placed in the lower right hand corner of your overall UI. Here's some code and inline comments to illustrate the point.

Note, this may be of particular value to those working with scroll views since it's common to design around a single content view that determines its size (and communicates this to the scroll view) dynamically based on whatever you put in it. Good luck, hope this helps somebody out there.

In simple words,

applicationContext.xml defines the beans that are shared among all the servlets. If your application have more than one servlet, then defining the common resources in the applicationContext.xml would make more sense.

spring-servlet.xml defines the beans that are related only to that servlet. Here it is the dispatcher servlet. So, your Spring MVC controllers must be defined in this file.

There is nothing wrong in defining all the beans in the spring-servlet.xml if you are running only one servlet in your web application.

The PowerShell string evaluation is calling ToString() on the DataSet. In order to evaluate any properties (or method calls), you have to force evaluation by enclosing the expression in $()

for($i=0;$i -lt $ds.Tables[1].Rows.Count;$i++)
{ 
  write-host "value is : $i $($ds.Tables[1].Rows[$i][0])"
}

Additionally foreach allows you to iterate through a collection or array without needing to figure out the length.

Rewritten (and edited for compile) -

foreach ($Row in $ds.Tables[1].Rows)
{ 
  write-host "value is : $($Row[0])"
}

The way i am going to tell you, will allow you to change the labels of legend, axis, title etc with a single formula and you don't need to use memorise multiple formulas. This will not affect the font style or the design of the labels/ text of titles and axis.

I am giving the complete answer of the question below.

 library(ggplot2)
 rating <- c(rnorm(200), rnorm(200, mean=.8))
 cond <-factor(rep(c("A", "B"), each = 200))
 df <- data.frame(cond,rating 
             )

 k<- ggplot(data=df, aes(x=rating, fill=cond))+ 
 geom_density(alpha = .3) +
 xlab("NEW RATING TITLE") +
 ylab("NEW DENSITY TITLE")

 # to change the cond to a different label
 k$labels$fill="New Legend Title"

 # to change the axis titles
 k$labels$y="Y Axis"
 k$labels$x="X Axis"
 k

I have stored the ggplot output in a variable "k". You can name it anything you like. Later I have used

k$labels$fill ="New Legend Title"

to change the legend. "fill" is used for those labels which shows different colours. If you have labels that shows sizes like 1 point represent 100, other point 200 etc then you can use this code like this-

k$labels$size ="Size of points"

and it will change that label title.

You might try running the script through JSLint.

Don't forget, for strings, you can always use:

String.IsNullOrEmpty(str)

Instead of:

str==null || str==""

As you said:

if you are adding conditions dynamically you don't have to worry about stripping the initial AND that's the only reason could be, you are right.

//%%%%%%%%%%%%%%%%%%%%%% HEX to ASCII %%%%%%%%%%%%%%%%%%%%%%
public String convertHexToString(String hex){

 String ascii="";
 String str;

 // Convert hex string to "even" length
 int rmd,length;
 length=hex.length();
 rmd =length % 2;
 if(rmd==1)
 hex = "0"+hex;

  // split into two characters
  for( int i=0; i<hex.length()-1; i+=2 ){

      //split the hex into pairs
      String pair = hex.substring(i, (i + 2));
      //convert hex to decimal
      int dec = Integer.parseInt(pair, 16);
      str=CheckCode(dec);
      ascii=ascii+" "+str;
  }
  return ascii;
}

public String CheckCode(int dec){
  String str;

          //convert the decimal to character
        str = Character.toString((char) dec);

      if(dec<32 || dec>126 && dec<161)
             str="n/a";  
  return str;
}

All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)

Based on this related answer, you are looking at a list that looks like: A-Z, a-z, 0-9, -, ., _, ~, :, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, %, and =. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. % can only be used in conjunction with url encoding as in %20), the RFC has all of these specifics.

Above answer's holds good.

Just an add-on for anyone who is into async-await rather than promise !!

const findAllFoo = async (req, resp, next) => {
    const pageSize = 10;
    const currentPage = 1;

    try {
        const foos = await FooModel.find() // find all documents
            .skip(pageSize * (currentPage - 1)) // we will not retrieve all records, but will skip first 'n' records
            .limit(pageSize); // will limit/restrict the number of records to display

        const numberOfFoos = await FooModel.countDocuments(); // count the number of records for that model

        resp.setHeader('max-records', numberOfFoos);
        resp.status(200).json(foos);

    } catch (err) {
        resp.status(500).json({
            message: err
        });
    }
};

It also works with almost any version of Visual Studio, you just need to change the "8.0" in the registry key to the appropriate version number for your version of Visual Studio.

The guide line shows up in the Output window too. (Visual Studio 2010 corrects this, and the line only shows up in the code editor window.)

You can also have the guide in multiple columns by listing more than one number after the color specifier:

RGB(230,230,230), 4, 80

Puts a white line at column 4 and column 80. This should be the value of a string value Guides in "Text Editor" key (see bellow).

Be sure to pick a line color that will be visisble on your background. This color won't show up on the default background color in VS. This is the value for a light grey: RGB(221, 221, 221).

Here are the registry keys that I know of:

Visual Studio 2010: HKCU\Software\Microsoft\VisualStudio\10.0\Text Editor

Visual Studio 2008: HKCU\Software\Microsoft\VisualStudio\9.0\Text Editor

Visual Studio 2005: HKCU\Software\Microsoft\VisualStudio\8.0\Text Editor

Visual Studio 2003: HKCU\Software\Microsoft\VisualStudio\7.1\Text Editor

For those running Visual Studio 2010, you may want to install the following extensions rather than changing the registry yourself:

• http://visualstudiogallery.msdn.microsoft.com/en-us/0fbf2878-e678-4577-9fdb-9030389b338c

• http://visualstudiogallery.msdn.microsoft.com/en-us/7f2a6727-2993-4c1d-8f58-ae24df14ea91

These are also part of the Productivity Power Tools, which includes many other very useful extensions.

Remember these 3 points:

• The Margin is the extra space around the control.
• The Padding is extra space inside the control.
• The Padding of an outer control is the Margin of an inner control.

It seems to me that your Hibernate libraries are not found (NoClassDefFoundError: org/hibernate/boot/archive/scan/spi/ScanEnvironment as you can see above).

Try checking to see if Hibernate core is put in as dependency:

  <artifactId>hibernate-core</artifactId>
  <version>5.0.11.Final</version>
  <scope>compile</scope>

You can use this code block for JFrame background color.

    JFrame frame = new JFrame("Frame BG color");
    frame.setLayout(null);
    
    frame.setSize(1000, 650);
    frame.getContentPane().setBackground(new Color(5, 65, 90));
    frame.setLocationRelativeTo(null);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setResizable(false);
    frame.setVisible(true);

You can delete all breakpoints using

del <start_breakpoint_num> - <end_breakpoint_num>

To view the start_breakpoint_num and end_breakpoint_num use:

You'll see the demo code is just a start/stop/reset millisecond counter. If you want to do fanciful formatting on the time, that's completely up to you. This should be more than enough to get you started.

This was a fun little project to work on. Here's how I'd approach it

var Stopwatch = function(elem, options) {

  var timer       = createTimer(),
      startButton = createButton("start", start),
      stopButton  = createButton("stop", stop),
      resetButton = createButton("reset", reset),
      offset,
      clock,
      interval;

  // default options
  options = options || {};
  options.delay = options.delay || 1;

  // append elements     
  elem.appendChild(timer);
  elem.appendChild(startButton);
  elem.appendChild(stopButton);
  elem.appendChild(resetButton);

  // initialize
  reset();

  // private functions
  function createTimer() {
    return document.createElement("span");
  }

  function createButton(action, handler) {
    var a = document.createElement("a");
    a.href = "#" + action;
    a.innerHTML = action;
    a.addEventListener("click", function(event) {
      handler();
      event.preventDefault();
    });
    return a;
  }

  function start() {
    if (!interval) {
      offset   = Date.now();
      interval = setInterval(update, options.delay);
    }
  }

  function stop() {
    if (interval) {
      clearInterval(interval);
      interval = null;
    }
  }

  function reset() {
    clock = 0;
    render();
  }

  function update() {
    clock += delta();
    render();
  }

  function render() {
    timer.innerHTML = clock/1000; 
  }

  function delta() {
    var now = Date.now(),
        d   = now - offset;

    offset = now;
    return d;
  }

  // public API
  this.start  = start;
  this.stop   = stop;
  this.reset  = reset;
};

Get some basic HTML wrappers for it

<!-- create 3 stopwatches -->
<div class="stopwatch"></div>
<div class="stopwatch"></div>
<div class="stopwatch"></div>

Usage is dead simple from there

var elems = document.getElementsByClassName("stopwatch");

for (var i=0, len=elems.length; i<len; i++) {
  new Stopwatch(elems[i]);
}

As a bonus, you get a programmable API for the timers as well. Here's a usage example

var elem = document.getElementById("my-stopwatch");
var timer = new Stopwatch(elem, {delay: 10});

// start the timer
timer.start();

// stop the timer
timer.stop();

// reset the timer
timer.reset();

jQuery plugin

As for the jQuery portion, once you have nice code composition as above, writing a jQuery plugin is easy mode

(function($) {

  var Stopwatch = function(elem, options) {
    // code from above...
  };

  $.fn.stopwatch = function(options) {
    return this.each(function(idx, elem) {
      new Stopwatch(elem, options);
    });
  };
})(jQuery);

jQuery plugin usage

// all elements with class .stopwatch; default delay (1 ms)
$(".stopwatch").stopwatch();

// a specific element with id #my-stopwatch; custom delay (10 ms)
$("#my-stopwatch").stopwatch({delay: 10});

It isn't bad practice, but it can make code less readable. One useful refactoring to work around this is to move the loop to a separate method, and then use a return statement instead of a break, for example this (example lifted from @Chris's answer):

String item;

for(int x = 0; x < 10; x++)
{
    // Linear search.
    if(array[x].equals("Item I am looking for"))
    {
        //you've found the item. Let's stop.
        item = array[x];
        break; 
    }
}

can be refactored (using extract method) to this:

public String searchForItem(String itemIamLookingFor)
{
    for(int x = 0; x < 10; x++)
    {
        if(array[x].equals(itemIamLookingFor))
        {
            return array[x];
        }
    }
}

Which when called from the surrounding code can prove to be more readable.

When is called the map.merge

        BiConsumer<M, T> accumulator
            = (map, element) -> map.merge(keyMapper.apply(element),
                                          valueMapper.apply(element), mergeFunction);

It will do a null check as first thing

if (value == null)
    throw new NullPointerException();

I don't use Java 8 so often so i don't know if there are a better way to fix it, but fix it is a bit hard.

You could do:

Use filter to filter all NULL values, and in the Javascript code check if the server didn't send any answer for this id means that he didn't reply to it.

Something like this:

Map<Integer, Boolean> answerMap =
        answerList
                .stream()
                .filter((a) -> a.getAnswer() != null)
                .collect(Collectors.toMap(Answer::getId, Answer::getAnswer));

Or use peek, which is used to alter the stream element for element. Using peek you could change the answer to something more acceptable for map but it means edit your logic a bit.

Sounds like if you want to keep the current design you should avoid Collectors.toMap

I had to create a timer for teachers grading students' work. Here's one I used which is entirely based on elapsed time since the grading begun by storing the system time at the point that the page is loaded, and then comparing it every half second to the system time at that point:

var startTime = Math.floor(Date.now() / 1000); //Get the starting time (right now) in seconds
localStorage.setItem("startTime", startTime); // Store it if I want to restart the timer on the next page

function startTimeCounter() {
    var now = Math.floor(Date.now() / 1000); // get the time now
    var diff = now - startTime; // diff in seconds between now and start
    var m = Math.floor(diff / 60); // get minutes value (quotient of diff)
    var s = Math.floor(diff % 60); // get seconds value (remainder of diff)
    m = checkTime(m); // add a leading zero if it's single digit
    s = checkTime(s); // add a leading zero if it's single digit
    document.getElementById("idName").innerHTML = m + ":" + s; // update the element where the timer will appear
    var t = setTimeout(startTimeCounter, 500); // set a timeout to update the timer
}

function checkTime(i) {
    if (i < 10) {i = "0" + i};  // add zero in front of numbers < 10
    return i;
}

startTimeCounter();

This way, it really doesn't matter if the 'setTimeout' is subject to execution delays, the elapsed time is always relative the system time when it first began, and the system time at the time of update.

One more, although I use cycle, but thi is much faster than math operands

power of two "floor" option:

int power = 1;
while (x >>= 1) power <<= 1;

power of two "ceil" option:

int power = 2;
x--;    // <<-- UPDATED
while (x >>= 1) power <<= 1;

UPDATE

As mentioned in comments there was mistake in ceil where its result was wrong.

Here are full functions:

unsigned power_floor(unsigned x) {
    int power = 1;
    while (x >>= 1) power <<= 1;
    return power;
}

unsigned power_ceil(unsigned x) {
    if (x <= 1) return 1;
    int power = 2;
    x--;
    while (x >>= 1) power <<= 1;
    return power;
}

Because the people who created Java wanted boolean to mean unambiguously true or false, not 1 or 0.

There's no consensus among languages about how 1 and 0 convert to booleans. C uses any nonzero value to mean true and 0 to mean false, but some UNIX shells do the opposite. Using ints weakens type-checking, because the compiler can't guard against cases where the int value passed in isn't something that should be used in a boolean context.

I have seen this question very often in the web and in my opinion, many people with high reputation did not answer these questions properly. So I would like to express my own answer here.

First we should consider there is a difference between array and arraylist.

The question asks for adding an element to an array, and not ArrayList

The answer is quite simple. It can be done in 3 steps.

1. Convert array to an arraylist
2. Add element to the arrayList
3. Convert back the new arrayList to the array

Here is the simple picture of it

And finally here is the code:

Step 1:

public List<String> convertArrayToList(String[] array){
        List<String> stringList = new ArrayList<String>(Arrays.asList(array));
        return stringList;
    }

Step 2:

public  List<String> addToList(String element,List<String> list){

            list.add(element);
            return list;
    }

Step 3:

public String[] convertListToArray(List<String> list){
           String[] ins = (String[])list.toArray(new String[list.size()]);
           return ins;
    } 

Step 4

public String[] addNewItemToArray(String element,String [] array){
        List<String> list = convertArrayToList(array);
        list= addToList(element,list);
        return  convertListToArray(list);
}

A bit late but I used jQuery ajax method. But I did not want to send a request every second if I haven't got the response back from the last request, so I did this.

function request(){
            if(response == true){
                // This makes it unable to send a new request 
                // unless you get response from last request
                response = false;
                var req = $.ajax({
                    type:"post",
                    url:"request-handler.php",
                    data:{data:"Hello World"}
                });

                req.done(function(){
                    console.log("Request successful!");

                    // This makes it able to send new request on the next interval
                    response = true;
                });
            }

            setTimeout(request(),1000);
        }

        request();

Is your link to another web page? If so, perhaps you could put the variable in the query string and set the session variable when the page being linked to is loaded.

So the link looks like this:

<a href="home.php?variable=value" name="home">home</a>

And the homge page would parse the query string and set the session variable.

ChildForm child = new ChildForm();
child.Owner = this;
child.Show();

// In ChildForm_Load:

private void ChildForm_Load(object sender, EventArgs e) 
{
  this.Owner.Enabled = false;
}

private void ChildForm_Closed(object sender, EventArgs e) 
{
  this.Owner.Enabled = true;
}

    public void replaceFragment(Fragment fragment, @Nullable Bundle bundle, boolean popBackStack, boolean findInStack) {
        FragmentManager fm = getSupportFragmentManager();
        FragmentTransaction ft = fm.beginTransaction();
        String tag = fragment.getClass().getName();
        Fragment parentFragment;
        if (findInStack && fm.findFragmentByTag(tag) != null) {
            parentFragment = fm.findFragmentByTag(tag);
        } else {
            parentFragment = fragment;
        }
        // if user passes the @bundle in not null, then can be added to the fragment
        if (bundle != null)
            parentFragment.setArguments(bundle);

        ft.replace(R.id.contenedor_principal, parentFragment, tag);
        ft.commit();
        fm.executePendingTransactions();

replaceFragment(f, null, boolean true, true); 

public WebElement fluientWaitforElement(WebElement element, int timoutSec, int pollingSec) {

    FluentWait<WebDriver> fWait = new FluentWait<WebDriver>(driver).withTimeout(timoutSec, TimeUnit.SECONDS)

        .ignoring(NoSuchElementException.class, TimeoutException.class).ignoring(StaleElementReferenceException.class);

    for (int i = 0; i < 2; i++) {
        try {

        fWait.until(ExpectedConditions.visibilityOf(element));
        fWait.until(ExpectedConditions.elementToBeClickable(element));
        } catch (Exception e) {

        System.out.println("Element Not found trying again - " + element.toString().substring(70));
        e.printStackTrace();

        }
    }

    return element;

    }

Use POST instead

Although it is easy to construct a GET query using window.open(), it's a bad idea (see below). One workaround is to create a form that submits a POST request. Like so:

<form id="helper" action="###/your_page###" style="display:none">
<inputtype="hidden" name="headerData" value="(default)">
</form>

<input type="button" onclick="loadNnextPage()" value="Click me!">

<script>
function loadNnextPage() {
  document.getElementById("helper").headerData.value = "New";
  document.getElementById("helper").submit();
}
</script>

Of course you will need something on the server side to handle this; as others have suggested you could create a "proxy" script that sends headers on your behalf and returns the results.

Problems with GET

• Query strings get stored in browser history,
• can be shoulder-surfed
• copy-pasted,
• and often you don't want it to be easy to "refresh" the same transaction.

Better is to Make a global Constants class to save key or variables to fetch or save data.

To save data call this method to save data from every where.

public static void saveData(Context con, String variable, String data)
{
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(con);
    prefs.edit().putString(variable, data).commit();
}

Use it to get data.

public static String getData(Context con, String variable, String defaultValue)
{
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(con);
    String data = prefs.getString(variable, defaultValue);
    return data;
}

and a method something like this will do the trick

public static User getUserInfo(Context con)
{
    String id =  getData(con, Constants.USER_ID, null);
    String name =  getData(con, Constants.USER_NAME, null);
    if(id != null && name != null)
    {
            User user = new User(); //Hope you will have a user Object.
            user.setId(id);
            user.setName(name);
            //Here set other credentials.
            return user;
    }
    else
    return null;
}

Though it is an old question, it is still a valid one.

Expected behavior:

• Show selected file name after upload.
• Do not do anything if the user clicks Cancel.
• Show the file name even when the user selects the same file.

Code with a demonstration:

<!DOCTYPE html>
<html>

<head>
  <title>File upload event</title>
</head>

<body>
  <form action="" method="POST" enctype="multipart/form-data">
    <input type="file" name="userFile" id="userFile"><br>
    <input type="submit" name="upload_btn" value="upload">
  </form>
  <script type="text/javascript">
    document.getElementById("userFile").onchange = function(e) {
      alert(this.value);
      this.value = null;
    }
  </script>
</body>

</html>

Explanation:

• The onchange event handler is used to handle any change in file selection event.
• The onchange event is triggered only when the value of an element is changed. So, when we select the same file using the input field the event will not be triggered. To overcome this, I set this.value = null; at the end of the onchange event function. It sets the file path of the selected file to null. Thus, the onchange event is triggered even at the time of the same file selection.

Try this: (Python version)

"(A-Za-z0-9 ){2, 25}"

change the upper limit based on your data set

Dim SourcePath As String = "c:\SomeFolder\SomeFileYouWantToCopy.txt" 'This is just an example string and could be anything, it maps to fileToCopy in your code.
Dim SaveDirectory As string = "c:\DestinationFolder"

Dim Filename As String = System.IO.Path.GetFileName(SourcePath) 'get the filename of the original file without the directory on it
Dim SavePath As String = System.IO.Path.Combine(SaveDirectory, Filename) 'combines the saveDirectory and the filename to get a fully qualified path.

If System.IO.File.Exists(SavePath) Then
   'The file exists
Else
    'the file doesn't exist
End If

A very simple way of doing this is to use reset_index() method.For a data frame df use the code below:

df.reset_index(inplace=True)

This way, the index will become a column, and by using inplace as True,this become permanent change.
