I use the below mentioned process to convert equations to markdown. This works very well for me. Its very simple!!

Let's say, I want to represent matrix multiplication equation

Step 1:

Get the script for your formulae from here - https://csrgxtu.github.io/2015/03/20/Writing-Mathematic-Fomulars-in-Markdown/

My example: I wanted to represent Z(i,j)=X(i,k) * Y(k, j); k=1 to n into a summation formulae.



Referencing the website, the script needed was => Z_i_j=\sum_{k=1}^{10} X_i_k * Y_k_j

Step 2:

Use URL encoder - https://www.urlencoder.org/ to convert the script to a valid url

My example:

Step 3:

Use this website to generate the image by copy-pasting the output from Step 2 in the "eq" request parameter - http://www.sciweavers.org/tex2img.php?eq=<b><i>paste-output-here</i></b>&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=

- My example:
http://www.sciweavers.org/tex2img.php?eq=Z_i_j=\sum_{k=1}^{10}%20X_i_k%20*%20Y_k_j&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=

Step 4:

Reference image using markdown syntax - ![alt text](enter url here)

- Copy this in your markdown and you are good to go:

![Z(i,j)=X(i,k) * Y(k, j); k=1 to n](http://www.sciweavers.org/tex2img.php?eq=Z_i_j%3D%5Csum_%7Bi%3D1%7D%5E%7B10%7D%20X_i_k%20%2A%20Y_k_j&bc=White&fc=Black&im=jpg&fs=12&ff=arev&edit=)

Image below is the output of markdown. Hurray!!

The only way I was able to get C# Express 2008 to work was to move the database file. So, I opened up SQL Server Management Studio and after dropping the database, I copied the file to my project folder. Then I reattached the database to management studio. Now, when I try to attach to the local copy it works. Apparently, you can not use the same database file more than once.

def visit_v2(device_code, camera_code):
    image1 = MultipartParam.from_file("files", "/home/yuzx/1.txt")
    image2 = MultipartParam.from_file("files", "/home/yuzx/2.txt")
    datagen, headers = multipart_encode([('device_code', device_code), ('position', 3), ('person_data', person_data), image1, image2])
    print "".join(datagen)
    if server_port == 80:
        port_str = ""
    else:
        port_str = ":%s" % (server_port,)
    url_str = "http://" + server_ip + port_str + "/adopen/device/visit_v2"
    headers['nothing'] = 'nothing'
    request = urllib2.Request(url_str, datagen, headers)
    try:
        response = urllib2.urlopen(request)
        resp = response.read()
        print "http_status =", response.code
        result = json.loads(resp)
        print resp
        return result
    except urllib2.HTTPError, e:
        print "http_status =", e.code
        print e.read()

Here's a quick code snippet that will find the first non-empty line in a string:

string line1;
while (
    ((line1 = sr.ReadLine()) != null) &&
    ((line1 = line1.Trim()).Length == 0)
)
{ /* Do nothing - just trying to find first non-empty line*/ }

if(line1 == null){ /* Error - no non-empty lines in string */ }

I also had this issue using Lumen, but fixed by setting DB_STRICT_MODE=false in .env file.

They aren't really concepts but rather specific keywords that tend to occur (with slightly different semantics) in popular languages like C++ and Java.

Essentially, they are meant to allow a class to restrict access to members (fields or functions). The idea is that the less one type is allowed to access in another type, the less dependency can be created. This allows the accessed object to be changed more easily without affecting objects that refer to it.

Broadly speaking, public means everyone is allowed to access, private means that only members of the same class are allowed to access, and protected means that members of subclasses are also allowed. However, each language adds its own things to this. For example, C++ allows you to inherit non-publicly. In Java, there is also a default (package) access level, and there are rules about internal classes, etc.

int32 and time.Duration are different types. You need to convert the int32 to a time.Duration, such as time.Sleep(time.Duration(rand.Int31n(1000)) * time.Millisecond).

In matrix multiplication there are 3 for loop, we are using since execution of each for loop requires time complexity O(n). So for three loops it becomes O(n^3)

TCPDF 6.2.11 (2015-08-02)

Some things won't work when included within <style> tags, however they will if added in a style="" attribute in the HTML tag. E.g. table padding – this doesn't work:

table {
    padding: 5px;
}

This does:

<table style="padding: 5px;">

From API 21 `getDrawable(int id)` is deprecated

So now you need to use

ResourcesCompat.getDrawable(context.getResources(), R.drawable.img_user, null)

But Best way to do is :

object ResourceUtils {
    fun getColor(context: Context, color: Int): Int {
        return ResourcesCompat.getColor(context.getResources(), color, null)
    }

    fun getDrawable(context: Context, drawable: Int): Drawable? {
        return ResourcesCompat.getDrawable(context.getResources(), drawable, null)
    }
}

use this method like :

Drawable img=ResourceUtils.getDrawable(context, R.drawable.img_user)
image.setImageDrawable(img);

Things to know in general:

1. Key != Password
   • SecretKeySpec expects a key, not a password. See below
2. It might be due to a policy restriction that prevents using 32 byte keys. See other answer on that

In your case

The problem is number 1: you are passing the password instead of the key.

AES only supports key sizes of 16, 24 or 32 bytes. You either need to provide exactly that amount or you derive the key from what you type in.

There are different ways to derive the key from a passphrase. Java provides a PBKDF2 implementation for such a purpose.

I used erickson's answer to paint a complete picture (only encryption, since the decryption is similar, but includes splitting the ciphertext):

SecureRandom random = new SecureRandom();
byte[] salt = new byte[16];
random.nextBytes(salt);

KeySpec spec = new PBEKeySpec("password".toCharArray(), salt, 65536, 256); // AES-256
SecretKeyFactory f = SecretKeyFactory.getInstance("PBKDF2WithHmacSHA1");
byte[] key = f.generateSecret(spec).getEncoded();
SecretKeySpec keySpec = new SecretKeySpec(key, "AES");

byte[] ivBytes = new byte[16];
random.nextBytes(ivBytes);
IvParameterSpec iv = new IvParameterSpec(ivBytes);

Cipher c = Cipher.getInstance("AES/CBC/PKCS5Padding");
c.init(Cipher.ENCRYPT_MODE, keySpec, iv);
byte[] encValue = c.doFinal(valueToEnc.getBytes());

byte[] finalCiphertext = new byte[encValue.length+2*16];
System.arraycopy(ivBytes, 0, finalCiphertext, 0, 16);
System.arraycopy(salt, 0, finalCiphertext, 16, 16);
System.arraycopy(encValue, 0, finalCiphertext, 32, encValue.length);

return finalCiphertext;

Other things to keep in mind:

• Always use a fully qualified Cipher name. AES is not appropriate in such a case, because different JVMs/JCE providers may use different defaults for mode of operation and padding. Use AES/CBC/PKCS5Padding. Don't use ECB mode, because it is not semantically secure.
• If you don't use ECB mode then you need to send the IV along with the ciphertext. This is usually done by prefixing the IV to the ciphertext byte array. The IV is automatically created for you and you can get it through cipherInstance.getIV().
• Whenever you send something, you need to be sure that it wasn't altered along the way. It is hard to implement a encryption with MAC correctly. I recommend you to use an authenticated mode like CCM or GCM.

A comprehensive list of browser versions supporting the async parameter is available here

Since it doesn't appear that anyone has mentioned it here yet, the new best way to manage HttpClient and HttpClientHandler in .NET Core 2.1 is using HttpClientFactory.

It solves most of the aforementioned issues and gotchas in a clean and easy-to-use way. From Steve Gordon's great blog post:

Add the following packages to your .Net Core (2.1.1 or later) project:

Microsoft.AspNetCore.All
Microsoft.Extensions.Http

Add this to Startup.cs:

services.AddHttpClient();

Inject and use:

[Route("api/[controller]")]
public class ValuesController : Controller
{
    private readonly IHttpClientFactory _httpClientFactory;

    public ValuesController(IHttpClientFactory httpClientFactory)
    {
        _httpClientFactory = httpClientFactory;
    }

    [HttpGet]
    public async Task<ActionResult> Get()
    {
        var client = _httpClientFactory.CreateClient();
        var result = await client.GetStringAsync("http://www.google.com");
        return Ok(result);
    }
}

def random_int(min, max)
    rand(max - min) + min
end

This will also work and you don't need the extra class:

#navigation li li {}

If you have a third level of LI's you may have to reset/override some of the styles they will inherit from the above selector. You can target the third level like so:

#navigation li li li {}

#on ubuntu, in /usr/share/jenkins:

sudo service jenkins stop
sudo mv jenkins.war jenkins.war.old
sudo wget https://updates.jenkins-ci.org/latest/jenkins.war
sudo service jenkins start

Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.

http://logging.apache.org/log4net/

Are you looking for actual infinity or the minimal finite value? If the former, use

-numeric_limits<double>::infinity()

which only works if

numeric_limits<double>::has_infinity

Otherwise, you should use

numeric_limits<double>::lowest()

which was introduces in C++11.

If lowest() is not available, you can fall back to

-numeric_limits<double>::max()

which may differ from lowest() in principle, but normally doesn't in practice.

You mean fast enumeration? You question is very unclear.

A normal for loop would look a bit like this:

unsigned int i, cnt = [someArray count];
for(i = 0; i < cnt; i++)
{ 
   // do loop stuff
   id someObject = [someArray objectAtIndex:i];
}

And a loop with fast enumeration, which is optimized by the compiler, would look like this:

for(id someObject in someArray)
{
   // do stuff with object
}

Keep in mind that you cannot change the array you are using in fast enumeration, thus no deleting nor adding when using fast enumeration

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

to import static methods/fields use

import static full.package.name.of.SomeClass.staticMethod;
import static full.package.name.of.SomeClass.staticField;

Yes.

var data = {_x000D_

};_x000D_

Blocking in Node.js is not necessary, even when developing tight hardware solutions. See temporal.js which does not use setTimeout or setIntervalsetImmediate. Instead, it uses setImmediate or nextTick which give much higher resolution task execution, and you can create a linear list of tasks. But you can do it without blocking the thread.

Here's a short, simple generic answer with a nice syntax for a named tuple with default arguments:

import collections

def dnamedtuple(typename, field_names, **defaults):
    fields = sorted(field_names.split(), key=lambda x: x in defaults)
    T = collections.namedtuple(typename, ' '.join(fields))
    T.__new__.__defaults__ = tuple(defaults[field] for field in fields[-len(defaults):])
    return T

Usage:

Test = dnamedtuple('Test', 'one two three', two=2)
Test(1, 3)  # Test(one=1, three=3, two=2)

Minified:

def dnamedtuple(tp, fs, **df):
    fs = sorted(fs.split(), key=df.__contains__)
    T = collections.namedtuple(tp, ' '.join(fs))
    T.__new__.__defaults__ = tuple(df[i] for i in fs[-len(df):])
    return T

Generally, you cannot send a POST request using sendRedirect() method. You can use RequestDispatcher to forward() requests with parameters within the same web application, same context.

RequestDispatcher dispatcher = servletContext().getRequestDispatcher("test.jsp");
dispatcher.forward(request, response);

The HTTP spec states that all redirects must be in the form of a GET (or HEAD). You can consider encrypting your query string parameters if security is an issue. Another way is you can POST to the target by having a hidden form with method POST and submitting it with javascript when the page is loaded.

You are actually getting the correct value out.

The way your x86 (compatible) processor stores data like this, is in Little Endian order, meaning that, the MSB is last in your output.

So, given your output:

10101010

the last two hex values 10 are the Most Significant Byte (2 hex digits = 1 byte = 8 bits (for (possibly unnecessary) clarification).

So, by reversing the memory storage order of the bytes, your value is actually: 01010101.

Hope that clears it up!

widget['bg'] = '#000000'

or

widget['background'] = '#000000'

would also work as hex-valued colors are also accepted.

When using the $array.Add()-method, you're trying to add the element into the existing array. An array is a collection of fixed size, so you will receive an error because it can't be extended.

$array += $element creates a new array with the same elements as old one + the new item, and this new larger array replaces the old one in the $array-variable

You can use the += operator to add an element to an array. When you use it, Windows PowerShell actually creates a new array with the values of the original array and the added value. For example, to add an element with a value of 200 to the array in the $a variable, type:

    $a += 200

Source: about_Arrays

+= is an expensive operation, so when you need to add many items you should try to add them in as few operations as possible, ex:

$arr = 1..3    #Array
$arr += (4..5) #Combine with another array in a single write-operation

$arr.Count
5

If that's not possible, consider using a more efficient collection like List or ArrayList (see the other answer).

I have implemented something similar for a different reason - that was code to tell the end user whether the foreground and background colors that they selected would result in unreadable text. To do this, rather than examining the RGB values, I converted the color value to HSL/HSV and then determined by experimentation what my cutoff point was for readability when comparing the fg and bg values. This is something you may want/need to consider.

Kotlin way

editText.setOnFocusChangeListener { _, hasFocus ->
    if (!hasFocus) {  }
}

The trunk is the main line of development in a SVN repository.

A branch is a side-line of development created to make larger, experimental or disrupting work without annoying users of the trunk version. Also, branches can be used to create development lines for multiple versions of the same product, like having a place to backport bugfixes into a stable release.

Finally, tags are markers to highlight notable revisions in the history of the repository, usually things like "this was released as 1.0".

See the HTML version of "Version Control with Subversion", especially Chapter 4: Branching and Merging or buy it in paper (e.g. from amazon) for an in-depth discussion of the technical details.

As others (e.g. Peter Neubauer below) the underlying implementation as /tags /branches and /trunk directories is only conventional and not in any way enforced by the tools. Violating these conventions leads to confusion all around, as this breaks habits and expectations of others accessing the repository. Special care must be taken to avoid committing new changes into tags, which should be frozen.

I use TortoiseSVN but no Visual Studio integration. I keep the "Check for modifications" dialog open on the second monitor the whole time, so I can track which files I have touched. But see the "Best SVN Tools" question, for more recommendations.

This is the simple answer I can give.

?

this is a character . You can do copy/past without problem

A non-query way would be to use the Sql Server Management Studio.

Locate the table, right click and choose "View dependencies".

EDIT

But, as the commenters said, it is not very reliable.

The answer is explained here.

To quote:

A class is free to implement comparison any way it chooses, and it can choose to make comparison against None mean something (which actually makes sense; if someone told you to implement the None object from scratch, how else would you get it to compare True against itself?).

Practically-speaking, there is not much difference since custom comparison operators are rare. But you should use is None as a general rule.

Cache

Clear your cache. http://support.google.com/chrome/bin/answer.py?hl=en&answer=95582 And test another browser.

Some where able to get an updated favicon by adding an URL parameter: ?v=1 after the link href which changes the resource link and therefore loads the favicon without cache (thanks @Stanislav).

<link rel="icon" type="image/x-icon" href="favicon.ico?v=2"  />

Favicon Usage

How did you import the favicon? How you should add it.

Normal favicon:

<link rel="icon" href="favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="favicon.ico" type="image/x-icon" />

PNG/GIF favicon:

<link rel="icon" type="image/gif" href="favicon.gif" />
<link rel="icon" type="image/png" href="favicon.png" />

in the <head> Tag.

Chrome local problem

Another thing could be the problem that chrome can't display favicons, if it's local (not uploaded to a webserver). Only if the file/icon would be in the downloads directory chrome is allowed to load this data - more information about this can be found here: local (file://) website favicon works in Firefox, not in Chrome or Safari- why?

Renaming

Try to rename it from favicon.{whatever} to {yourfaviconname}.{whatever} but I would suggest you to still have the normal favicon. This has solved my issue on IE.

Base64 approach

Found another solution for this which works great! I simply added my favicon as Base64 Encoded Image directly inside the tag like this:

Used this page here for this: http://www.motobit.com/util/base64-decoder-encoder.asp

Generate favicons

I can really suggest you this page: http://www.favicon-generator.org/ to create all types of favicons you need.

• First test if the module is loaded
• Then import

```

if (Get-Module -ListAvailable -Name <<MODULE_NAME>>) {
    Write-Verbose -Message "<<MODULE_NAME>> Module does not exist." -Verbose
}
if (!(Get-Module -Name <<MODULE_NAME>>)) {
    Get-Module -ListAvailable <<MODULE_NAME>> | Import-Module | Out-Null
}

```

In the command line type service apache2 status then hit enter. The result should say:

Apache2 is running (pid xxxx)

Following commands we can use for Linux or Mac. For Windows we can use below on git bash.

List all files, first level folders, and their contents

ls * -r

List all first-level subdirectories and files

file */*

Save file list to text

file */* *>> ../files.txt
file */* -r *>> ../files-recursive.txt

Get everything

find . -type f

Save everything to file

find . -type f > ../files-all.txt

Well you can ask the help of regex, the great in here :)

code:

import re

string = 'adsfg34wrtwe4r2_()' #your string that needs to be matched.
regex = r'^[\w\d_()]*$' # you can also add a space in regex if u want to allow it in the string  
if re.match(regex,string):
    print 'yes'
else: 
    print 'false'

Output:

yes  

Hope this helps :)

Using the base package:

df <- data.frame(days = c(88, 11, 2, 5, 22, 1, 222, 2), name = c("Lynn", "Tom", "Chris", "Lisa", "Kyla", "Tom", "Lynn", "Lynn"))

# Three lines
target <- c("Tom", "Lynn")
index <- df$name %in% target
df[index, ]

# One line
df[df$name %in% c("Tom", "Lynn"), ] 

Output:

  days name
1   88 Lynn
2   11  Tom
6    1  Tom
7  222 Lynn
8    2 Lynn

Using sqldf:

library(sqldf)
# Two alternatives:
sqldf('SELECT *
      FROM df 
      WHERE name = "Tom" OR name = "Lynn"')
sqldf('SELECT *
      FROM df 
      WHERE name IN ("Tom", "Lynn")')

In JavaScript:

document.getElementById("id").style.display = null;

In jQuery:

$("#id").css('display',null);

As pointed out, "&" in python performs a bitwise and operation, just as it does in C#. and is the appropriate equivalent to the && operator.

Since we're dealing with booleans (i == 5 is True and ii == 10 is also True), you may wonder why this didn't either work anyway (True being treated as an integer quantity should still mean True & True is a True value), or throw an exception (eg. by forbidding bitwise operations on boolean types)

The reason is operator precedence. The "and" operator binds more loosely than ==, so the expression: "i==5 and ii==10" is equivalent to: "(i==5) and (ii==10)"

However, bitwise & has a higher precedence than "==" (since you wouldn't want expressions like "a & 0xff == ch" to mean "a & (0xff == ch)"), so the expression would actually be interpreted as:

if i == (5 & ii) == 10:

Which is using python's operator chaining to mean: does the valuee of ii anded with 5 equal both i and 10. Obviously this will never be true.

You would actually get (seemingly) the right answer if you had included brackets to force the precedence, so:

if (i==5) & (ii=10)

would cause the statement to be printed. It's the wrong thing to do, however - "&" has many different semantics to "and" - (precedence, short-cirtuiting, behaviour with integer arguments etc), so it's fortunate that you caught this here rather than being fooled till it produced less obvious bugs.

If you do not have the pandas and sqlalchemy libraries, import using pip

pip install pandas
pip install sqlalchemy

We can use pandas and sqlalchemy to directly insert into the database

import csv
import pandas as pd
from sqlalchemy import create_engine, types

engine = create_engine('mysql://root:*Enter password here*@localhost/*Enter Databse name here*') # enter your password and database names here

df = pd.read_csv("Excel_file_name.csv",sep=',',quotechar='\'',encoding='utf8') # Replace Excel_file_name with your excel sheet name
df.to_sql('Table_name',con=engine,index=False,if_exists='append') # Replace Table_name with your sql table name

Another solution would have been to consider date written as Ymd.

Written in this "format" this is much easy to compare dates.

$paymentDate       = date('Ymd'); // on 4th may 2016, would have been 20160504
$contractBegin     = 20010101;
$contractEnd       = 20160101;
echo ($paymentDate >= $contractBegin && $paymentDate <= $contractEnd) ? "Between" : "Not Between";

It will always work for every day of the year and do not depends on any function or conversion (PHP will consider the int value of $paymentDate to compare with the int value of contractBegin and contractEnd).

Try float property. Here's an example: http://jsfiddle.net/mLmHR/

Open your font-awesome.css theres code like :

@font-face {
  font-family: 'FontAwesome';
  src: url('../fonts/fontawesome-webfont.eot?v=4.5.0');
  src: url('../fonts/fontawesome-webfont.eot?#iefix&v=4.5.0') format('embedded-opentype'), url('../fonts/fontawesome-webfont.woff2?v=4.5.0') format('woff2'), url('../fonts/fontawesome-webfont.woff?v=4.5.0') format('woff'), url('../fonts/fontawesome-webfont.ttf?v=4.5.0') format('truetype'), url('../fonts/fontawesome-webfont.svg?v=4.5.0#fontawesomeregular') format('svg');
  font-weight: normal;
  font-style: normal;
}

you must have folder like :

font awesome -> css
             -> fonts

or the easiest way :

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.4.0/css/font-awesome.min.css">

Tag ids must be unique. You are updating the span with ID 'ItemCostSpan' of which there are two. Give the span a class and get it using find.

    $("legend").each(function() {
        var SoftwareItem = $(this).text();
        itemCost = GetItemCost(SoftwareItem);
        $("input:checked").each(function() {               
            var Component = $(this).next("label").text();
            itemCost += GetItemCost(Component);
        });            
        $(this).find(".ItemCostSpan").text("Item Cost = $ " + itemCost);
    });

As mentioned by @Sebastian the default solution should aim to use run(): https://docs.python.org/3/library/subprocess.html#subprocess.run

Here a convenient implementation (feel free to change the log class with print statements or what ever other logging functionality you are using):

import subprocess

def _run_command(command):
    log.debug("Command: {}".format(command))
    result = subprocess.run(command, shell=True, capture_output=True)
    if result.stderr:
        raise subprocess.CalledProcessError(
                returncode = result.returncode,
                cmd = result.args,
                stderr = result.stderr
                )
    if result.stdout:
        log.debug("Command Result: {}".format(result.stdout.decode('utf-8')))
    return result

And sample usage (code is unrelated, but I think it serves as example of how readable and easy to work with errors it is with this simple implementation):

try:
    # Unlock PIN Card
    _run_command(
        "sudo qmicli --device=/dev/cdc-wdm0 -p --uim-verify-pin=PIN1,{}"
        .format(pin)
    )

except subprocess.CalledProcessError as error:
    if "couldn't verify PIN" in error.stderr.decode("utf-8"):
        log.error(
                "SIM card could not be unlocked. "
                "Either the PIN is wrong or the card is not properly connected. "
                "Resetting module..."
                )
        _reset_4g_hat()
        return

//Just use a List
//create the list
public final List<Object> myObjects;

//instantiate the list
myObjects = new ArrayList<Object>();

//add objects to the list
Object object = myObject;
myObjects.add(object);

//remove the object calling this method if you have more than 1 objects still works with 1
//object too.

private void removeObject(){
int len = myObjects.size();
for(int i = 0;i<len; i++){
Objects object = myObjects.get(i);
myObjects.remove(object);
}
}

There is no specific event for capturing browser close event.

You can only capture on unload of the current page.

By this method, it will be effected while refreshing / navigating the current page.

Even calculating of X Y postion of the mouse event doesn't give you good result.

So - the solution of providing a base works given that all of the paths have the same base path. But if you want to provide different base paths, this still won't work.

One way I solved this problem was by making the beginning of the path relative. For your case:

gulp.src([
    'index.php',
    '*css/**/*',
    '*js/**/*',
    '*src/**/*',
])
.pipe(gulp.dest('/var/www/'));

The reason this works is that Gulp sets the base to be the end of the first explicit chunk - the leading * causes it to set the base at the cwd (which is the result that we all want!)

This only works if you can ensure your folder structure won't have certain paths that could match twice. For example, if you had randomjs/ at the same level as js, you would end up matching both.

This is the only way that I have found to include these as part of a top-level gulp.src function. It would likely be simple to create a plugin/function that could separate out each of those globs so you could specify the base directory for them, however.

To augment LazyOne's answer, here is an annotated version of the answer.

<rewrite>
  <rules>
     <clear />
     <rule name="Redirect all requests to https" stopProcessing="true">
       <match url="(.*)" />
         <conditions logicalGrouping="MatchAll">
           <add input="{HTTPS}" pattern="off" ignoreCase="true" />
         </conditions>
         <action 
            type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" 
            redirectType="Permanent" appendQueryString="false" />
     </rule>
  </rules>
</rewrite>

Clear all the other rules that might already been defined on this server. Create a new rule, that we will name "Redirect all requests to https". After processing this rule, do not process any more rules! Match all incoming URLs. Then check whether all of these other conditions are true: HTTPS is turned OFF. Well, that's only one condition (but make sure it's true). If it is, send a 301 Permanent redirect back to the client at http://www.foobar.com/whatever?else=the#url-contains. Don't add the query string at the end of that, because it would duplicate the query string!

This is what the properties, attributes, and some of the values mean.

• clear removes all server rules that we might otherwise inherit.
• rule defines a rule.
  • name an arbitrary (though unique) name for the rule.
  • stopProcessing whether to forward the request immediately to the IIS request pipeline or first to process additional rules.
• match when to run this rule.
  • url a pattern against which to evaluate the URL
• conditions additional conditions about when to run this rule; conditions are processed only if there is first a match.
  • logicalGrouping whether all the conditions must be true (MatchAll) or any of the conditions must be true (MatchAny); similar to AND vs OR.
• add adds a condition that must be met.
  • input the input that a condition is evaluating; input can be server variables.
  • pattern the standard against which to evaluate the input.
  • ignoreCase whether capitalization matters or not.
• action what to do if the match and its conditions are all true.
  • type can generally be redirect (client-side) or rewrite (server-side).
  • url what to produce as a result of this rule; in this case, concatenate https:// with two server variables.
  • redirectType what HTTP redirect to use; this one is a 301 Permanent.
  • appendQueryString whether to add the query string at the end of the resultant url or not; in this case, we are setting it to false, because the {REQUEST_URI} already includes it.

The server variables are

• {HTTPS} which is either OFF or ON.
• {HTTP_HOST} is www.mysite.com, and
• {REQUEST_URI} includes the rest of the URI, e.g. /home?key=value
  • the browser handles the #fragment (see comment from LazyOne).

First up you need to download Selenium jar files from http://www.seleniumhq.org/download/. Then you'd need an IDE, something like IntelliJ or Eclipse. Then you'll have to map your jar files to those IDEs. Then depending on which language/framework you choose, you'll have to download the relevant library files, for example, if you're using JUnit you'll have to download Junit 4.11 jar file. Finally don't forget to download the drivers for Chrome and Safari (firefox driver comes standard with selenium). Once done, you can start coding and testing your code with the browser of your choice.

Here's my Code to theme the alert dialog box:

<style name="alertDialog" parent="Theme.AppCompat.Dialog.Alert">
    <item name="android:background">@color/light_button_text_color</item>
    <item name="android:textColor">@android:color/black</item>
    <item name="android:textColorPrimary">@android:color/black</item>
    <item name="android:textColorSecondary">@android:color/black</item>
    <item name="android:titleTextColor" tools:targetApi="m">@android:color/black</item>
</style>

Place this code in styles.xml. In your java apply this theme as:

AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.alertDialog);

Why not look to the RFC that currently defines Base64?

Base encoding of data is used in many situations to store or transfer
data in environments that, perhaps for legacy reasons, are restricted to US-ASCII [1] data.Base encoding can also be used in new applications that do not have legacy restrictions, simply because it makes it possible to manipulate objects with text editors.

In the past, different applications have had different requirements and thus sometimes implemented base encodings in slightly different ways. Today, protocol specifications sometimes use base encodings in general, and "base64" in particular, without a precise description or reference. Multipurpose Internet Mail Extensions (MIME) [4] is often used as a reference for base64 without considering the consequences for line-wrapping or non-alphabet characters. The purpose of this specification is to establish common alphabet and encoding considerations. This will hopefully reduce ambiguity in other documents, leading to better interoperability.

Base64 was originally devised as a way to allow binary data to be attached to emails as a part of the Multipurpose Internet Mail Extensions.

I had to purge my ffmpeg and then install another one from a ppa:

sudo apt-get purge ffmpeg
sudo apt-add-repository -y ppa:jon-severinsson/ffmpeg 
sudo apt-get update 
sudo apt-get install ffmpeg

Then convert:

 ffmpeg -i audio.ogg -f mp3 newfile.mp3

All you need is in the documentation.

If you want to set the form size programmatically, set the form's StartPosition property to Manual. Otherwise the form's own positioning and sizing algorithm will interfere with yours. This is why you are experiencing the problems mentioned in your question.

Example: Here is how I resize the form to a size half-way between its original size and the size of the screen's working area. I also center the form in the working area:

public MainView()
{
    InitializeComponent();

    // StartPosition was set to FormStartPosition.Manual in the properties window.
    Rectangle screen = Screen.PrimaryScreen.WorkingArea;
    int w = Width >= screen.Width ? screen.Width : (screen.Width + Width) / 2;
    int h = Height >= screen.Height ? screen.Height : (screen.Height + Height) / 2;
    this.Location = new Point((screen.Width - w) / 2, (screen.Height - h) / 2);
    this.Size = new Size(w, h);
}

Note that setting WindowState to FormWindowState.Maximized alone does not change the size of the restored window. So the window might look good as long as it is maximized, but when restored, the window size and location can still be wrong. So I suggest setting size and location even when you intend to open the window as maximized.

You can also use the jsPDF-AutoTable plugin. You can check out a demo here that uses the following code.

var doc = new jsPDF('p', 'pt');
var elem = document.getElementById("basic-table");
var res = doc.autoTableHtmlToJson(elem);
doc.autoTable(res.columns, res.data);
doc.save("table.pdf");

This works well for coping entire records.

UPDATE your_table
SET new_field = sourse_field

For my case, I restarted the server and it worked.

You can simply use:

mvn --settings YourOwnSettings.xml clean install

or

mvn -s YourOwnSettings.xml clean install

"better" is relative. It all depends on what your needs are. Docker compose is for orchestrating multiple containers. If these images already exist in the docker registry, then it's better to list them in the compose file. If these images or some other images have to be built from files on your computer, then you can describe the processes of building those images in a Dockerfile.

I understand that Dockerfiles are used in Docker Compose, but I am not sure if it is good practice to put everything in one large Dockerfile with multiple FROM commands for the different images?

Using multiple FROM in a single dockerfile is not a very good idea because there is a proposal to remove the feature. 13026

If for instance, you want to dockerize an application which uses a database and have the application files on your computer, you can use a compose file together with a dockerfile as follows

docker-compose.yml

mysql:
  image: mysql:5.7
  volumes:
    - ./db-data:/var/lib/mysql
  environment:
    - "MYSQL_ROOT_PASSWORD=secret"
    - "MYSQL_DATABASE=homestead"
    - "MYSQL_USER=homestead"
  ports:
    - "3307:3306"
app:
  build:
    context: ./path/to/Dockerfile
    dockerfile: Dockerfile
  volumes:
    - ./:/app
  working_dir: /app
      

Dockerfile

I have to add to the answer of douglas, you can access the global config, but symfony translates some parameters, for example:

# config.yml
... 
framework:
    session:
        domain: 'localhost'
...

are

$this->container->parameters['session.storage.options']['domain'];

You can use var_dump to search an specified key or value.

yeah I had the same question for a long time and I found the perfect one. here are some parameters from it.

https://maps.google.com?parameter = value

q=

is used to specify the search query in Google maps search.
eg :

https://maps.google.com?q=newyork or
https://maps.google.com?q=51.03841,-114.01679

near=

is used to specify the location alternative to q=. Also has the added effect of allowing you to increase the AddressDetails Accuracy value by being more precise. Mostly only useful if query is a business or suchlike.

z=

Zoom level. Can be set 19 normally, but in certain cases can go up to 23.

ll=

Latitude and longitude of the map centre point. Must be in that order. Requires decimal format. Interestingly, you can use this without q, in which case it doesn’t show a marker.

sll=

Similar to ll, only this sets the lat/long of the centre point for a business search. Requires the same input criteria as ll.

t=

Sets the kind of map shown. Can be set to:

m – normal  map,
k – satellite,
h – hybrid,
p – terrain

saddr=

Sets the starting point for directions searches. You can also add text into this in brackets to bold it in the directions sidebar.

daddr=

Sets the end point for directions searches, and again will bold any text added in brackets.You can also add "+to:" which will set via points. These can be added multiple times.

via=

Allows you to insert via points in directions. Must be in CSV format. For example, via=1,5 addresses 1 and 5 will be via points without entries in the sidebar. The start point (which is set as 0), and 2, 3 and 4 will all show full addresses.

doflg=

Changes the units used to measure distance (will default to the standard unit in country of origin). Change to ptk for metric or ptm for imperial.

msa=

Does stuff with My Maps. Set to 0 show defined My Maps, b to turn the My Maps sidebar on, 1 to show the My Maps tab on its own, or 2 to go to the new My Map creator form.

dirflg=

can set miscellaneous values below:

h - Avoid highway
t - Avoid tolls

Firstly, understand that DateTime objects aren't formatted. They just store the Year, Month, Day, Hour, Minute, Second, etc as a numeric value and the formatting occurs when you want to represent it as a string somehow. You can compare DateTime objects without formatting them.

To compare an input date with DateTime.Now, you need to first parse the input into a date and then compare just the Year/Month/Day portions:

DateTime inputDate;
if(!DateTime.TryParse(inputString, out inputDate))
    throw new ArgumentException("Input string not in the correct format.");

if(inputDate.Date == DateTime.Now.Date) {
    // Same date!
}

Kyle's solution worked perfectly fine for me so I made my research in order to avoid any Js and CSS, but just sticking with HTML. Adding a value of selected to the item we want to appear as a header forces it to show in the first place as a placeholder. Something like:

<option selected disabled>Choose here</option>

The complete markup should be along these lines:

<select>
    <option selected disabled>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

You can take a look at this fiddle, and here's the result:

If you do not want the sort of placeholder text to appear listed in the options once a user clicks on the select box just add the hidden attribute like so:

<select>
    <option selected disabled hidden>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

Check the fiddle here and the screenshot below.

Here is the solution:

<select>
    <option style="display:none;" selected>Select language</option>
    <option>Option 1</option>
    <option>Option 2</option>
</select>

I used /etc/crontab. I used vi and entered in the PATHs I needed into this file and ran it as root. The normal crontab overwrites PATHs that you have set up. A good tutorial on how to do this.

The systemwide cron file looks like this:

This has the username field, as used by /etc/crontab.
# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file.
# This file also has a username field, that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# m h dom mon dow user   command
42 6 * * *   root    run-parts --report /etc/cron.daily
47 6 * * 7   root    run-parts --report /etc/cron.weekly
52 6 1 * *   root    run-parts --report /etc/cron.monthly
01 01 * * 1-5 root python /path/to/file.py

It will depend on the implementation, but from the Sun Java 6 source code:

int newCapacity = (oldCapacity * 3)/2 + 1;

That's in the ensureCapacity method. Other JDK implementations may vary.

Why not use @media-queries? These are designed for that exact purpose. You can also do this with jQuery, but that's a last resort in my book.

var s = document.createElement("script");

//Check if viewport is smaller than 768 pixels
if(window.innerWidth < 768) {
    s.type = "text/javascript";
    s.src = "http://www.example.com/public/assets/css1";
}else { //Else we have a larger screen
    s.type = "text/javascript";
    s.src = "http://www.example.com/public/assets/css2";
}

$(function(){
    $("head").append(s); //Inject stylesheet
})

document.getElementById(this).innerHTML = '';

Put it inside your if-case. What it does is just to check for the current object within the document and replace it with nothing. You'll have too loop through the list first, I am guessing you are already doing that since you have that if.

If anyone using MS SQL Server 2008 and higher lands on this question: SQL Server 2008 and higher has a new "hierarchyId" feature designed specifically for this task.

More info at https://docs.microsoft.com/en-us/sql/relational-databases/hierarchical-data-sql-server

The following code will allow you to have two headings on the same line, the first left-aligned and the second right-aligned, and has the added advantage of keeping both headings on the same baseline.

The HTML Part:

<h1 class="text-left-right">
    <span class="left-text">Heading Goes Here</span>
    <span class="byline">Byline here</span>
</h1>

And the CSS:

.text-left-right {
    text-align: right;
    position: relative;
}
.left-text {
    left: 0;
    position: absolute;
}
.byline {
    font-size: 16px;
    color: rgba(140, 140, 140, 1);
}

lint is a tool that is used to mark the source code with some suspicious and non-structural (may cause bug). It is a static code analysis tool in C at the beginning.Now it became the generic term used to describe the software analysis tool that mark the suspicious code.

What this function does is it checks if the property exist on this class of any of his child's, and if so it gets the value otherwise it returns null. So now the properties are optional and dynamic.

/**
 * check if property is defined on this class or any of it's childes and return it
 *
 * @param $property
 *
 * @return bool
 */
private function getIfExist($property)
{
    $value = null;
    $propertiesArray = get_object_vars($this);

    if(array_has($propertiesArray, $property)){
        $value = $propertiesArray[$property];
    }

    return $value;
}

Usage:

const CONFIG_FILE_PATH_PROPERTY = 'configFilePath';

$configFilePath = $this->getIfExist(self::CONFIG_FILE_PATH_PROPERTY);

Get the version of Boost that you require. This is for 1.55 but feel free to change or manually download yourself:

wget -O boost_1_55_0.tar.gz https://sourceforge.net/projects/boost/files/boost/1.55.0/boost_1_55_0.tar.gz/download
tar xzvf boost_1_55_0.tar.gz
cd boost_1_55_0/

Get the required libraries, main ones are icu for boost::regex support:

sudo apt-get update
sudo apt-get install build-essential g++ python-dev autotools-dev libicu-dev libbz2-dev libboost-all-dev

Boost's bootstrap setup:

./bootstrap.sh --prefix=/usr/

Then build it with:

./b2

and eventually install it:

sudo ./b2 install

You can use either the xml attribute android:cursorVisible="false" or programatically:

• java: view.setCursorVisible(false)
• kotlin: view.isCursorVisible = false

I think you can achieve this the quickest by using the where function:

For example looking for items greater than 0.2 in a numpy array and replacing those with 0:

import numpy as np

nums = np.random.rand(4,3)

print np.where(nums > 0.2, 0, nums)

int(round(x))

Will round it and change it to integer

EDIT:

You are not assigning int(round(h)) to any variable. When you call int(round(h)), it returns the integer number but does nothing else; you have to change that line for:

h = int(round(h))

To assign the new value to h

EDIT 2:

As @plowman said in the comments, Python's round() doesn't work as one would normally expect, and that's because the way the number is stored as a variable is usually not the way you see it on screen. There are lots of answers that explain this behavior:

round() doesn't seem to be rounding properly

One way to avoid this problem is to use the Decimal as stated by this answer: https://stackoverflow.com/a/15398691/4345659

In order for this answer to work properly without using extra libraries it would be convenient to use a custom rounding function. After a lot of corrections, I came up with the following solution, that as far as I tested avoided all the storing issues. It is based on using the string representation, obtained with repr() (NOT str()!). It looks hacky but it was the only way I found to solve all the cases. It works with both Python2 and Python3.

def proper_round(num, dec=0):
    num = str(num)[:str(num).index('.')+dec+2]
    if num[-1]>='5':
        return float(num[:-2-(not dec)]+str(int(num[-2-(not dec)])+1))
    return float(num[:-1])

Tests:

>>> print(proper_round(1.0005,3))
1.001
>>> print(proper_round(2.0005,3))
2.001
>>> print(proper_round(3.0005,3))
3.001
>>> print(proper_round(4.0005,3))
4.001
>>> print(proper_round(5.0005,3))
5.001
>>> print(proper_round(1.005,2))
1.01
>>> print(proper_round(2.005,2))
2.01
>>> print(proper_round(3.005,2))
3.01
>>> print(proper_round(4.005,2))
4.01
>>> print(proper_round(5.005,2))
5.01
>>> print(proper_round(1.05,1))
1.1
>>> print(proper_round(2.05,1))
2.1
>>> print(proper_round(3.05,1))
3.1
>>> print(proper_round(4.05,1))
4.1
>>> print(proper_round(5.05,1))
5.1
>>> print(proper_round(1.5))
2.0
>>> print(proper_round(2.5))
3.0
>>> print(proper_round(3.5))
4.0
>>> print(proper_round(4.5))
5.0
>>> print(proper_round(5.5))
6.0
>>> 
>>> print(proper_round(1.000499999999,3))
1.0
>>> print(proper_round(2.000499999999,3))
2.0
>>> print(proper_round(3.000499999999,3))
3.0
>>> print(proper_round(4.000499999999,3))
4.0
>>> print(proper_round(5.000499999999,3))
5.0
>>> print(proper_round(1.00499999999,2))
1.0
>>> print(proper_round(2.00499999999,2))
2.0
>>> print(proper_round(3.00499999999,2))
3.0
>>> print(proper_round(4.00499999999,2))
4.0
>>> print(proper_round(5.00499999999,2))
5.0
>>> print(proper_round(1.0499999999,1))
1.0
>>> print(proper_round(2.0499999999,1))
2.0
>>> print(proper_round(3.0499999999,1))
3.0
>>> print(proper_round(4.0499999999,1))
4.0
>>> print(proper_round(5.0499999999,1))
5.0
>>> print(proper_round(1.499999999))
1.0
>>> print(proper_round(2.499999999))
2.0
>>> print(proper_round(3.499999999))
3.0
>>> print(proper_round(4.499999999))
4.0
>>> print(proper_round(5.499999999))
5.0

Finally, the corrected answer would be:

# Having proper_round defined as previously stated
h = int(proper_round(h))

EDIT 3:

Tests:

>>> proper_round(6.39764125, 2)
6.31 # should be 6.4
>>> proper_round(6.9764125, 1)
6.1  # should be 7

The gotcha here is that the dec-th decimal can be 9 and if the dec+1-th digit >=5 the 9 will become a 0 and a 1 should be carried to the dec-1-th digit.

If we take this into consideration, we get:

def proper_round(num, dec=0):
    num = str(num)[:str(num).index('.')+dec+2]
    if num[-1]>='5':
      a = num[:-2-(not dec)]       # integer part
      b = int(num[-2-(not dec)])+1 # decimal part
      return float(a)+b**(-dec+1) if a and b == 10 else float(a+str(b))
    return float(num[:-1])

In the situation described above b = 10 and the previous version would just concatenate a and b which would result in a concatenation of 10 where the trailing 0 would disappear. This version transforms b to the right decimal place based on dec, as a proper carry.

\n is a line break. /n is not.

use of \n with

1. echo directly to page

Now if you are trying to echo string to the page:

echo  "kings \n garden";

output will be:

kings garden

you won't get garden in new line because PHP is a server-side language, and you are sending output as HTML, you need to create line breaks in HTML. HTML doesn't understand \n. You need to use the nl2br() function for that.

What it does is:

Returns string with <br /> or <br> inserted before all newlines (\r\n, \n\r, \n and \r).

echo  nl2br ("kings \n garden");

Output

kings
garden

Note Make sure you're echoing/printing \n in double quotes, else it will be rendered literally as \n. because php interpreter parse string in single quote with concept of as is

so "\n" not '\n'

2. write to text file

Now if you echo to text file you can use just \n and it will echo to a new line, like:

$myfile = fopen("test.txt", "w+")  ;

$txt = "kings \n garden";
fwrite($myfile, $txt);
fclose($myfile);
 

output will be:

kings
 garden

It is not clear why you want to do this. If you want to get the correct numerical value, you could use unary + ^[docs]:

value = +value;

If you just want to format the text, then regex could be better. It depends on the values you are dealing with I'd say. If you only have integers, then

input.value = +input.value;

is fine as well. Of course it also works for float values, but depending on how many digits you have after the point, converting it to a number and back to a string could (at least for displaying) remove some.

jezrael's answer is good, but did not answer a question I had: Will getting the "sort" flag wrong mess up my data in any way? The answer is apparently "no", you are fine either way.

from pandas import DataFrame, concat

a = DataFrame([{'a':1,      'c':2,'d':3      }])
b = DataFrame([{'a':4,'b':5,      'd':6,'e':7}])

>>> concat([a,b],sort=False)
   a    c  d    b    e
0  1  2.0  3  NaN  NaN
0  4  NaN  6  5.0  7.0

>>> concat([a,b],sort=True)
   a    b    c  d    e
0  1  NaN  2.0  3  NaN
0  4  5.0  NaN  6  7.0

In newer versions of typescript you can use:

type Customers = Record<string, Customer>

In older versions you can use:

var map: { [email: string]: Customer; } = { };
map['[email protected]'] = new Customer(); // OK
map[14] = new Customer(); // Not OK, 14 is not a string
map['[email protected]'] = 'x'; // Not OK, 'x' is not a customer

You can also make an interface if you don't want to type that whole type annotation out every time:

interface StringToCustomerMap {
    [email: string]: Customer;
}

var map: StringToCustomerMap = { };
// Equivalent to first line of above

Remove the project from your solution by right-clicking it in the Solution Explorer window and choosing Remove. Move the entire project folder, including subdirectories wherever you want it to go. Add the project back to your solution.

Namespace names is something completely different, just edit the source code.

These steps work for me:

1. Download the Rcpp manually from WebSite (https://cran.r-project.org/web/packages/Rcpp/index.html)
2. unzip the folder/files to "Rcpp" folder
3. Locate the "library" folder under R install directory Ex: C:\R\R-3.3.1\library
4. Copy the "Rcpp" folder to Library folder.

Good to go!!!

library(Rcpp)
library(ggplot2) 

Try this:

net use * /delete /y

The /y key makes it select Yes in prompt silently

I know its a bit late now, but you could do something such as this:

function AddToArray ($post_information) {
    //Create the return array
    $return = array();
    //Iterate through the array passed
    foreach ($post_information as $key => $value) {
        //Append the key and value to the array, e.g.
            //$_POST['keys'] = "values" would be in the array as "keys"=>"values"
        $return[$key] = $value;
    }
    //Return the created array
    return $return;
}

The test with:

if (isset($_POST['submit'])) {
    var_dump(AddToArray($_POST));
}

This for me produced:

array (size=1)
  0 => 
    array (size=5)
      'stake' => string '0' (length=1)
      'odds' => string '' (length=0)
      'ew' => string 'false' (length=5)
      'ew_deduction' => string '' (length=0)
      'submit' => string 'Open' (length=4)

All answers above are correct, However People who are coming from other programming language. The easiest approach to follow will be.

variable = 1

print("length " + format(variable))

For this to work you have to really, really loosen your security settings (generally NOT recommended)

You will need to add the website to your "Trusted Zone", then go into the custom settings (scroll about 1/2 way down the page) and change:

ActiveX controls and plugins - Enable (or prompt)... any of the settings that apply to your code (I think the very last one is the one you are hitting) -- "script ActiveX controls marked safe for scripting*"

That all said, unless you have a really, really good reason for doing this - you are opening up a major "hole" in your browsers security... step very carefully... and do not expect that other end users will be willing to do the same.

A qualified id-expression is an unqualified id-expression prepended by a scope resolution operator ::, and optionally, a sequence of enumeration, (since C++11)class or namespace names or decltype expressions (since C++11) separated by scope resolution operators. For example, the expression std::string::npos is an expression that names the static member npos in the class string in namespace std. The expression ::tolower names the function tolower in the global namespace. The expression ::std::cout names the global variable cout in namespace std, which is a top-level namespace. The expression boost::signals2::connection names the type connection declared in namespace signals2, which is declared in namespace boost.

The keyword template may appear in qualified identifiers as necessary to disambiguate dependent template names]1

I find this simple T-SQL query useful for returning valid e-mail addresses

SELECT email
FROM People
WHERE email LIKE '%_@__%.__%' 
    AND PATINDEX('%[^a-z,0-9,@,.,_]%', REPLACE(email, '-', 'a')) = 0

The PATINDEX bit eliminates all e-mail addresses containing characters that are not in the allowed a-z, 0-9, '@', '.', '_' & '-' set of characters.

It can be reversed to do what you want like this:

SELECT email
FROM People
WHERE NOT (email LIKE '%_@__%.__%' 
    AND PATINDEX('%[^a-z,0-9,@,.,_]%', REPLACE(email, '-', 'a')) = 0)

This should work!

[HttpPost]
public ActionResult RedirectToImages(int id)
{
    return RedirectToAction("Index", "ProductImageManeger", new  { id = id });
}

[HttpGet]
public ViewResult Index(int id)
{
    return View(_db.ProductImages.Where(rs => rs.ProductId == id).ToList());
}

Notice that you don't have to pass the name of view if you are returning the same view as implemented by the action.

Your view should inherit the model as this:

@model <Your class name>

You can then access your model in view as:

@Model.<property_name>

server.error.whitelabel.enabled=false

Include the above line to the Resources folders application.properties

I have a much better code, made by me, it is so big, just to show both things... create a 4x4 table and vertical align more than just one cell.

It does not use any IE hack, no vertical-align:middle; at all...

It does not use for vertical centering display-table, display:table-rom; display:table-cell;

It uses the trick of a container that has two divs, one hidden (position is not the correct but makes parent have the correct variable size), one visible just after the hidden but with top:-50%; so it is mover to correct position.

See div classes that make the trick: BloqueTipoContenedor BloqueTipoContenedor_VerticalmenteCentrado BloqueTipoContenido_VerticalmenteCentrado_Oculto BloqueTipoContenido_VerticalmenteCentrado_Visible

Please sorry for using Spanish on classes names (it is because i speak spanish and this is so tricky that if i use English i get lost).

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

First, ensure that /dev/ttyUSB0 works. E.g. plug in mouse and check it works. Second, try select other board. It is often that non-original boards do not recognized correctly under their names. Third, try press reset button manually while uploading sketch. Probably automatic reset is broken.

Use the Immediate Window to Execute Commands

The Immediate Window can also be used to execute commands. Just type a > followed by the command.

For example >shell cmd will start a command shell (this can be useful to check what environment variables were passed to Visual Studio, for example). >cls will clear the screen.

Here is a list of commands that are so commonly used that they have their own aliases: https://msdn.microsoft.com/en-us/library/c3a0kd3x.aspx

This notation (first seen here) looks useful too:

insert into postagem (
  resumopostagem,
  textopostagem,
  dtliberacaopostagem,
  idmediaimgpostagem,
  idcatolico,
  idminisermao,
  idtipopostagem
) select
  resumominisermao,
  textominisermao,
  diaminisermao,
  idmediaimgminisermao,
  idcatolico ,
  idminisermao,
  1
from
  minisermao    

Sometimes you do get focus but no cursor in a text field. In this case you would do this:

document.getElementById(frmObj.id).select();

SAMPLE.CSV
a, 1, +
b, 2, -
c, 3, *
d, 4, /
column_names = ["Letter", "Number", "Symbol"]
df = pd.read_csv("sample.csv", names=column_names)
print(df)
OUTPUT
  Letter  Number Symbol
0      a       1      +
1      b       2      -
2      c       3      *
3      d       4      /

letters = df.Letter.to_list()
print(letters)
OUTPUT
['a', 'b', 'c', 'd']

I am gonna explain with a simple example code which takes a compare function as parameter to another sorting function. Lets say I have a bubble sort function that takes a custom compare function and uses it instead of a fixed if statement.

Compare Function

bool compare(int a, int b) {
    return a > b;
}

Now , the Bubble sort that takes another function as its parameter to perform comparison

Bubble sort function

void bubble_sort(int arr[], int n, bool (&cmp)(int a, int b)) {

    for (int i = 0;i < n - 1;i++) {
        for (int j = 0;j < (n - 1 - i);j++) {
            
            if (cmp(arr[j], arr[j + 1])) {
                swap(arr[j], arr[j + 1]);
            }
        }
    }
}

Finally , the main which calls the Bubble sort function by passing the boolean compare function as argument.

int main()
{
    int i, n = 10, key = 11;
    int arr[10] = { 20, 22, 18, 8, 12, 3, 6, 12, 11, 15 };

    bubble_sort(arr, n, compare);
    cout<<"Sorted Order"<<endl;
    for (int i = 0;i < n;i++) {
        cout << arr[i] << " ";
    }
}

Output:

Sorted Order
3 6 8 11 12 12 15 18 20 22

Using Guava:

byte[] bytearray = Ints.toByteArray(1695609641);

I tested and used this command in kafka confluent V4.0.0 and apache kafka V 1.0.0 and 1.0.1

/opt/kafka/confluent-4.0.0/bin/kafka-configs --zookeeper XX.XX.XX.XX:2181 --entity-type topics --entity-name test --alter --add-config  retention.ms=55000

test is the topic name.

I think it works well in other versions too

The tool is called the SQL Server Profiler, it's still part of the standard toolset.

Width auto

The initial width of a block level element like div or p is auto. This makes it expand to occupy all available horizontal space within its containing block. If it has any horizontal padding or border, the widths of those do not add to the total width of the element.

Width 100%

On the other hand, if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border (unless you’ve used box-sizing:border-box, in which case only margins are added to the 100% to change how its total width is calculated). This may be what you want, but most likely it isn’t.

To visualise the difference see this picture:

Joey mentioned that Format-* is for human consumption. If you're writing to a file for machine consumption, maybe you want to use Export-*? Some good ones are

• Export-Csv - Comma separated value. Great for when you know what the columns are going to be
• Export-Clixml - You can export whole objects and collections. This is great for serialization.

If you want to read back in, you can use Import-Csv and Import-Clixml. I find that I like this better than inventing my own data formats (also it's pretty easy to whip up an Import-Ini if that's your preference).

Some answers here says that fs.exists and fs.existsSync are both deprecated. According to the docs this is no more true. Only fs.exists is deprected now:

Note that fs.exists() is deprecated, but fs.existsSync() is not. (The callback parameter to fs.exists() accepts parameters that are inconsistent with other Node.js callbacks. fs.existsSync() does not use a callback.)

So you can safely use fs.existsSync() to synchronously check if a file exists.

You can use json.loads:

import json
import requests

response = requests.get(...)
json_data = json.loads(response.text)

This converts a given string into a dictionary which allows you to access your JSON data easily within your code.

Or you can use @Martijn's helpful suggestion, and the higher voted answer, response.json().

BehaviorSubject vs Observable : RxJS has observers and observables, Rxjs offers a multiple classes to use with data streams, and one of them is a BehaviorSubject.

Observables : Observables are lazy collections of multiple values over time.

BehaviorSubject:A Subject that requires an initial value and emits its current value to new subscribers.

 // RxJS v6+
import { BehaviorSubject } from 'rxjs';

const subject = new BehaviorSubject(123);

//two new subscribers will get initial value => output: 123, 123
subject.subscribe(console.log);
subject.subscribe(console.log);

//two subscribers will get new value => output: 456, 456
subject.next(456);

//new subscriber will get latest value (456) => output: 456
subject.subscribe(console.log);

//all three subscribers will get new value => output: 789, 789, 789
subject.next(789);

// output: 123, 123, 456, 456, 456, 789, 789, 789

Nested loop method for removing duplicates in array and preserving original order of elements.

var array = [1, 3, 2, 1, [5], 2, [4]]; // INPUT

var element = 0;
var decrement = array.length - 1;
while(element < array.length) {
  while(element < decrement) {
    if (array[element] === array[decrement]) {
      array.splice(decrement, 1);
      decrement--;
    } else {
      decrement--;
    }
  }
  decrement = array.length - 1;
  element++;
}

console.log(array);// [1, 3, 2, [5], [4]]

Explanation: Inner loop compares first element of array with all other elements starting with element at highest index. Decrementing towards the first element a duplicate is spliced from the array.

When inner loop is finished the outer loop increments to the next element for comparison and resets the new length of the array.

Application Server:

Application server maintains the application logic and
serves the web pages in response to user request.

That means application server can do both application logic maintanence and web page serving.

Web Server:

Web server just serves the web pages and it cannot enforce any application logic.

Final conclusion is: Application server also contains the web server.

It's not possible using CSS, but using a CSS preprocessor like less or SASS.

There are infinite approaches.

Commands that output nothing:

break
cls
color
goto
pushd
popd
prompt
title

Weird Commands:

CD.
REM.
@echo off
cmd /c
START >FILE

The outdated print command produces a blank file:

print /d:EMPTY_TEXT_FILE nul

I have now spent quite some time trying to find a good date picker that support interval ranges, and eventually found this one:

http://keith-wood.name/datepick.html

I believe this may be the best jquery date picker for selecting a range or multiple dates, and it is claimed to have been the base for the jQuery UI datepicker, and I see no reason to doubt that since it seems to be really powerful, and also good documented !

You can overlay a big, semi-transparent <div> that takes all the clicks. Just append a new <div> to <body> with this style:

.overlay {
    background-color: rgba(1, 1, 1, 0.7);
    bottom: 0;
    left: 0;
    position: fixed;
    right: 0;
    top: 0;
}

For Visual Studio 2013 you need to remove that folder from this path:

%AppData%\..\Local\Microsoft\VisualStudio\12.0

ElasticSearch itself provides a way to create data backup and restoration. The simple command to do it is:

CURL -XPUT 'localhost:9200/_snapshot/<backup_folder name>/<backupname>' -d '{
    "indices": "<index_name>",
    "ignore_unavailable": true,
    "include_global_state": false
}'

Now, how to create, this folder, how to include this folder path in ElasticSearch configuration, so that it will be available for ElasticSearch, restoration method, is well explained here. To see its practical demo surf here.

The general idea is to sweep the function across. You have many options, one is apply():

R> set.seed(42)
R> M <- matrix(rnorm(40),ncol=4)
R> apply(M, 2, sd)
[1] 0.835449 1.630584 1.156058 1.115269
R> 

I have the same issue with you and I have change something in my server

you might try this

const root = require("path").join(__dirname, "./build");
app.use(express.static(root));
app.get("*", (req, res) => {
  res.sendFile("index.html", { root });
});

Returns only objects from the array whose property name is not "Kristian"

var noKristianArray = $.grep(someArray, function (el) { return el.name!= "Kristian"; });

 var someArray = [_x000D_
                {name:"Kristian", lines:"2,5,10"},_x000D_
                {name:"John", lines:"1,19,26,96"},_x000D_
                {name:"Kristian", lines:"2,58,160"},_x000D_
                {name:"Felix", lines:"1,19,26,96"}_x000D_
                ];_x000D_
    _x000D_
var noKristianArray = $.grep(someArray, function (el) { return el.name!= "Kristian"; });_x000D_
_x000D_
console.log(noKristianArray);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I had the same problem

Here is the Solution that might work for you. It worked for me

    GridView1.DataBind();
if (GridView1.Columns.Count > 0)
    GridView1.Columns[0].Visible = false;
else
{
    GridView1.HeaderRow.Cells[0].Visible = false;
    foreach (GridViewRow gvr in GridView1.Rows)
    {
        gvr.Cells[0].Visible = false;
    }
}

Yes it is possible but you can better use a div #mydiv and use both

$(document).ready(function(){});

//and

$("#mydiv").ready(function(){});

All scripting languages are programming languages.

Languages are not classed as script or not - it entirely depends on the execution environment.

If the environment is one that is interpreted, this is commonly referred to as a scripting environment.

pow(2.0,1.0)
pow(2.0,2.0)
pow(2.0,3.0)

Your original question title is misleading. To just square, use 2*2.

I'm using Visual Studio with Parallels/Win 7 on a MacBook laptop keyboard and the only thing that worked was Fn + Enter/Return (that's the Mac shortcut for Insert).

Instead of using this in your current class setClassRoomName("aClassName"); you have to use classroom.setClassRoomName("aClassName");

You have to add the class' and at a point like

yourClassNameWhereTheMethodIs.theMethodsName();

I know it's a really late answer but if someone starts learning Java and randomly sees this post he knows what to do.

Flutter web

For me the error occurred when I run my application in "release" mode

flutter run -d chrome --release

and when I deployed the application on the Firebase hosting

firebase deploy

Solution

Since I initialized Firebase in the index.html, I had to change the implementation order of firebase and main.dart.js

<script>
  var firebaseConfig = {
  apiKey: "xxxxxxxxxxxxxxxxxxxxxx",
  authDomain: "xxxxxxxxxxx.firebaseapp.com",
  databaseURL: "https://xxxxxxxxxx.firebaseio.com",
  projectId: "xxxxxxxxxxx",
  storageBucket: "xxxxxxxx.appspot.com",
  messagingSenderId: "xxxxxxxxxxx",
  appId: "1:xxxxxxxxxx:web:xxxxxxxxxxxxx",
  measurementId: "G-xxxxxxxxx"
  };
  // Initialize Firebase
  firebase.initializeApp(firebaseConfig);
  firebase.analytics();
</script>

//moved below firebase init
<script src="main.dart.js" type="application/javascript"></script>

Here's how

int i = Math.Abs(386792);
while(i >= 10)
    i /= 10;

and i will contain what you need

I had a Automated Billing setup online and the credit card said it say good Thru 10/09, but the card was rejected the first week in October and again the next week. Each time it was rejected it cost me a $10 fee. Don't assume it good thru the end of the month if you have automatic billing setup.

You can use HTML5 <figcaption>:

<figure>
  <img src="img.jpg" alt="my img"/>
  <figcaption> Your text </figcaption>
</figure>

Working example.

Use to_number to convert budgpost to a number:

when to_number(budgpost,99999) in (1001,1012,50055) THEN 'BP_GR_A' 

EDIT: Make sure there are enough 9's in to_number to match to largest budget post.

If there are non-numeric budget posts, you could filter them out with a where clause at then end of the query:

where regexp_like(budgpost, '^-?[[:digit:],.]+$')

While the code to create a custom Attribute is fairly simple, it's very important that you understand what attributes are:

Attributes are metadata compiled into your program. Attributes themselves do not add any functionality to a class, property or module - just data. However, using reflection, one can leverage those attributes in order to create functionality.

So, for instance, let's look at the Validation Application Block, from Microsoft's Enterprise Library. If you look at a code example, you'll see:

    /// <summary>
    /// blah blah code.

    [StringLengthValidator(8, RangeBoundaryType.Inclusive, 8, RangeBoundaryType.Inclusive, MessageTemplate = "\"{1}\" must always have \"{4}\" characters.")]
    public string Code { get; set; }

From the snippet above, one might guess that the code will always be validated, whenever changed, accordingly to the rules of the Validator (in the example, have at least 8 characters and at most 8 characters). But the truth is that the Attribute does nothing; as mentioned previously, it only adds metadata to the property.

However, the Enterprise Library has a Validation.Validate method that will look into your object, and for each property, it'll check if the contents violate the rule informed by the attribute.

So, that's how you should think about attributes -- a way to add data to your code that might be later used by other methods/classes/etc.

Was able to get this working:

ng-attr-aria-current="{{::item.isSelected==true ? 'page' : undefined}}"

The nice thing here is that if item.isSelected is false then the attribute simply isn't rendered.

Oracle documentation quoted the difference precisely.

inheritance: A class inherits fields and methods from all its superclasses, whether direct or indirect. A subclass can override methods that it inherits, or it can hide fields or methods that it inherits. (Note that hiding fields is generally bad programming practice.)

polymorphism: polymorphism refers to a principle in biology in which an organism or species can have many different forms or stages. This principle can also be applied to object-oriented programming and languages like the Java language. Subclasses of a class can define their own unique behaviors and yet share some of the same functionality of the parent class.

polymorphism is not applicable for fields.

Polymorphism vs Overriding vs Overloading

Most of the answers need to read the whole file before doing anything. This sample reads increasingly large samples from the end.

I only saw Murat Yükselen's answer while writing this answer. It's nearly the same, which I suppose is a good thing. The sample below also deals with \r and increases its buffersize at each step. I also have some unit tests to back this code up.

def readlines_reversed(f):
    """ Iterate over the lines in a file in reverse. The file must be
    open in 'rb' mode. Yields the lines unencoded (as bytes), including the
    newline character. Produces the same result as readlines, but reversed.
    If this is used to reverse the line in a file twice, the result is
    exactly the same.
    """
    head = b""
    f.seek(0, 2)
    t = f.tell()
    buffersize, maxbuffersize = 64, 4096
    while True:
        if t <= 0:
            break
        # Read next block
        buffersize = min(buffersize * 2, maxbuffersize)
        tprev = t
        t = max(0, t - buffersize)
        f.seek(t)
        lines = f.read(tprev - t).splitlines(True)
        # Align to line breaks
        if not lines[-1].endswith((b"\n", b"\r")):
            lines[-1] += head  # current tail is previous head
        elif head == b"\n" and lines[-1].endswith(b"\r"):
            lines[-1] += head  # Keep \r\n together
        elif head:
            lines.append(head)
        head = lines.pop(0)  # can be '\n' (ok)
        # Iterate over current block in reverse
        for line in reversed(lines):
            yield line
    if head:
        yield head

In a loop it's harmless, but in an assignment statement it can lead to unexpected results:

var x = 5;
var y = x++; // y is now 5 and x is 6
var z = ++x; // z is now 7 and x is 7

Whitespace between the variable and the operator can lead to unexpected results as well:

a = b = c = 1; a ++ ; b -- ; c; console.log('a:', a, 'b:', b, 'c:', c)

In a closure, unexpected results can be an issue as well:

var foobar = function(i){var count = count || i; return function(){return count++;}}

baz = foobar(1);
baz(); //1
baz(); //2


var alphabeta = function(i){var count = count || i; return function(){return ++count;}}

omega = alphabeta(1);
omega(); //2
omega(); //3

And it triggers automatic semicolon insertion after a newline:

var foo = 1, bar = 2, baz = 3, alpha = 4, beta = 5, delta = alpha
++beta; //delta is 4, alpha is 4, beta is 6

preincrement/postincrement confusion can produce off-by-one errors that are extremely difficult to diagnose. Fortunately, they are also complete unnecessary. There are better ways to add 1 to a variable.

I always use something like the following:

public static String GetTimestamp(this DateTime value)
{
    return value.ToString("yyyyMMddHHmmssfff");
}

This will give you a string like 200905211035131468, as the string goes from highest order bits of the timestamp to lowest order simple string sorting in your SQL queries can be used to order by date if you're sticking values in a database

I am assuming you are using java 7, thus you get a compiler warning, when you don't close the resource you should close your scanner usually in a finally block.

Scanner scanner = null;
try {
    scanner = new Scanner(System.in);
    //rest of the code
}
finally {
    if(scanner!=null)
        scanner.close();
}

Or even better: use the new Try with resource statement:

try(Scanner scanner = new Scanner(System.in)){
    //rest of your code
}

Depending on your applications, it might be easier to limit the memory the language interpreter uses. For example with Java you can set the amount of RAM the JVM will be allocated.

Otherwise it is possible to set it once for each process with the windows API

SetProcessWorkingSetSize Function

There are a number of things wrong with your code:

char *readFile(char *fileName)
{
    FILE *file;
    char *code = malloc(1000 * sizeof(char));
    file = fopen(fileName, "r");
    do 
    {
      *code++ = (char)fgetc(file);

    } while(*code != EOF);
    return code;
}

1. What if the file is greater than 1,000 bytes?
2. You are increasing code each time you read a character, and you return code back to the caller (even though it is no longer pointing at the first byte of the memory block as it was returned by malloc).
3. You are casting the result of fgetc(file) to char. You need to check for EOF before casting the result to char.

It is important to maintain the original pointer returned by malloc so that you can free it later. If we disregard the file size, we can achieve this still with the following:

char *readFile(char *fileName)
{
    FILE *file = fopen(fileName, "r");
    char *code;
    size_t n = 0;
    int c;

    if (file == NULL)
        return NULL; //could not open file

    code = malloc(1000);

    while ((c = fgetc(file)) != EOF)
    {
        code[n++] = (char) c;
    }

    // don't forget to terminate with the null character
    code[n] = '\0';        

    return code;
}

There are various system calls that will give you the size of a file; a common one is stat.

In order to Run Report Viewer On server with Data from Server

A) Go to Project Property ----> Select Reference ------> Add Reference

1) Import (Microsoft.ReportViewer.Common.dll)-----> (Path "C:\Program Files (x86)\Microsoft Visual Studio 10.0\ReportViewer")

2) Import (Microsoft.ReportViewer.ProcessingObjectModel.dll) -----> (Path "C:\Windows\Assembly\GAC_MSIL\Microsoft.ReportViewer.ProcessingObjectModel")

3) Import (Microsoft.ReportViewer.WebForms.dll)-----> (Path "C:\Program Files (x86)\Microsoft Visual Studio 10.0\ReportViewer")

B) In Above three DLL set its "Local Copy" to True so that while Building Deployment Package it will getcopied to "Bin" folder.

C) Publish the Solution

D) After that Upload all the files along with "Bin" folder with the help of "File Zilla" software to "Web Server".

E) This will install DLL on server hence, client is not required to have "Report Viewer.dll".

This worked for me.

here is the thing i did for the same trouble i had.

when I'm passing the text to the next page in jsp, i'm reading it as a textarea instead of reading something like

so the output came as you wanted. and for other properties, you can use as below.

<textarea style="background-color: white; border: none; width:660px;font-family: Arial, Helvetica, sans-serif; font-size:1.0em; resize:none;" name="text" cols="75" rows="15" readonly="readonly" ><s:property value="%{text}"/></textarea>

In my case, I needed an additional command,

git branch --unset-upstream

to get my renamed branch to push up to origin newname.

(For ease of typing), I first git checkout oldname. Then run the following:

git branch -m newname <br/> git push origin :oldname*or*git push origin --delete oldname
git branch --unset-upstream
git push -u origin newname or git push origin newname

This extra step may only be necessary because I (tend to) set up remote tracking on my branches via git push -u origin oldname. This way, when I have oldname checked out, I subsequently only need to type git push rather than git push origin oldname.

If I do not use the command git branch --unset-upstream before git push origin newbranch, git re-creates oldbranch and pushes newbranch to origin oldbranch -- defeating my intent.

It seems that resource filtering/searching can be implemented in a RESTful way. The idea is to introduce a new endpoint called /filters/ or /api/filters/.

Using this endpoint filter can be considered as a resource and hence created via POST method. This way - of course - body can be used to carry all the parameters as well as complex search/filter structures can be created.

After creating such filter there are two possibilities to get the search/filter result.

1. A new resource with unique ID will be returned along with 201 Created status code. Then using this ID a GET request can be made to /api/users/ like:

   GET /api/users/?filterId=1234-abcd
   

2. After new filter is created via POST it won't reply with 201 Created but at once with 303 SeeOther along with Location header pointing to /api/users/?filterId=1234-abcd. This redirect will be automatically handled via underlying library.

In both scenarios two requests need to be made to get the filtered results - this may be considered as a drawback, especially for mobile applications. For mobile applications I'd use single POST call to /api/users/filter/.

How to keep created filters?

They can be stored in DB and used later on. They can also be stored in some temporary storage e.g. redis and have some TTL after which they will expire and will be removed.

What are the advantages of this idea?

Filters, filtered results are cacheable and can be even bookmarked.

If you're using sqlplus in a shell, like bash you can run the shell's clear command from sqlplus:

In Swift 3 here's how you do it to the UIImage itself:

let size = CGSize(width: image.size.width, height: image.size.height)
UIGraphicsBeginImageContext(size)
let rect = CGRect(x: 0, y: 0, width: size.width, height: size.height)
image?.draw(in: rect, blendMode: .normal, alpha: 1.0)
let context = UIGraphicsGetCurrentContext()
context?.setStrokeColor(red: 0, green: 0, blue: 0, alpha: 1)
context?.stroke(rect)
let newImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()

self.imageView.image = newImage

Old question, but I just ran into this. Sometimes your files are UTF-8 with a BOM at the start, and your template engine doesn't like that. So when you include your template, you get another (invisible) BOM inserted into your page...

<body>{INVISIBLE BOM HERE}...</body>

This causes a gap at the start of your page, where the browser renders the BOM, but it looks invisible to you (and in the inspector, just shows up as whitespace/quotes.

Save your template files as UTF-8 without BOM, or change your template engine to correctly handle UTF8/BOM documents.

Well, I'm not sure if my solution is best practice. Using the NotificationBuilder my code looks like that:

private void showNotification() {
    Intent notificationIntent = new Intent(this, MainActivity.class);

    PendingIntent contentIntent = PendingIntent.getActivity(
                this, 0, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(contentIntent);
    NotificationManager notificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    notificationManager.notify(NOTIFICATION_ID, builder.build());
    }

Manifest:

    <activity
        android:name=".MainActivity"
        android:launchMode="singleInstance"
    </activity>

and here the Service:

    <service
        android:name=".services.ProtectionService"
        android:launchMode="singleTask">
    </service>

I don't know if there really is a singleTask at Service but this works properly at my application...

Do you mean to do:

cat test | \
while read CMD; do
echo $CMD
done

You can try using:

select trunc(sysdate - to_date('2009-10-01', 'yyyy-mm-dd')) as days from dual

This will definitely work for you...

ArrayList<String> list = new ArrayList<String>();

list.add(textview.getText().toString());
list.add("B");
list.add("C");

I was in a process of switching from one version control service to another and needed to clone all repositories including all branches, tags and history.

To achieve above I did next:

• manually checkout all branches to local repository (script to checkout all shown below),
• git push origin '*:*'

.sh script used to checkout all branches to local repository:

for branch in `git branch -a | grep remotes | grep -v HEAD | grep -v master `; do
   git branch --track ${branch#remotes/origin/} $branch
done

They're there to allow for different levels of encapsulation

From Python 3.0 changelog;

The StringIO and cStringIO modules are gone. Instead, import the io module and use io.StringIO or io.BytesIO for text and data respectively.

From the Python 3 email documentation it can be seen that io.StringIO should be used instead:

from io import StringIO
from email.generator import Generator
fp = StringIO()
g = Generator(fp, mangle_from_=True, maxheaderlen=60)
g.flatten(msg)
text = fp.getvalue()

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document.

Because no one actually created an answer with using .on() instead of bind() i decided to create one.

$('div#dialog').on('dialogclose', function(event) {
     //custom logic fired after dialog is closed.  
});

Can't you style the forms themselves? Then, style the divs accordingly.

form
{
    /* styles */
}

You can always overrule inherited styles by making it important:

form
{
    /* styles */ !important
}

There is better way to do this.

Adding an answer that exclusively uses the pandas library to read in a .csv file and save as a .xlsx file. This example makes use of pandas.read_csv (Link to docs) and pandas.dataframe.to_excel (Link to docs).

The fully reproducible example uses numpy to generate random numbers only, and this can be removed if you would like to use your own .csv file.

import pandas as pd
import numpy as np

# Creating a dataframe and saving as test.csv in current directory
df = pd.DataFrame(np.random.randn(100000, 3), columns=list('ABC'))
df.to_csv('test.csv', index = False)

# Reading in test.csv and saving as test.xlsx

df_new = pd.read_csv('test.csv')
writer = pd.ExcelWriter('test.xlsx')
df_new.to_excel(writer, index = False)
writer.save()

With jQuery, I've done it this way:

function checkKey(e){
     switch (e.keyCode) {
        case 40:
            alert('down');
            break;
        case 38:
            alert('up');
            break;
        case 37:
            alert('left');
            break;
        case 39:
            alert('right');
            break;
        default:
            alert('???');  
            }      
}

if ($.browser.mozilla) {
    $(document).keypress (checkKey);
} else {
    $(document).keydown (checkKey);
}

Just for completeness, the following is a Java solution. I am certain the same could be done in C# as well. It avoids having to specify the type anywhere in code - instead, you specify it in the strings you are trying to parse.

The problem is that there isn't any way to know which enumeration the String might match - so the answer is to solve that problem.

Instead of accepting just the string value, accept a String that has both the enumeration and the value in the form "enumeration.value". Working code is below - requires Java 1.8 or later. This would also make the XML more precise as in you would see something like color="Color.red" instead of just color="red".

You would call the acceptEnumeratedValue() method with a string containing the enum name dot value name.

The method returns the formal enumerated value.

import java.util.HashMap;
import java.util.Map;
import java.util.function.Function;


public class EnumFromString {

    enum NumberEnum {One, Two, Three};
    enum LetterEnum {A, B, C};


    Map<String, Function<String, ? extends Enum>> enumsByName = new HashMap<>();

    public static void main(String[] args) {
        EnumFromString efs = new EnumFromString();

        System.out.print("\nFirst string is NumberEnum.Two - enum is " + efs.acceptEnumeratedValue("NumberEnum.Two").name());
        System.out.print("\nSecond string is LetterEnum.B - enum is " + efs.acceptEnumeratedValue("LetterEnum.B").name());

    }

    public EnumFromString() {
        enumsByName.put("NumberEnum", s -> {return NumberEnum.valueOf(s);});
        enumsByName.put("LetterEnum", s -> {return LetterEnum.valueOf(s);});
    }

    public Enum acceptEnumeratedValue(String enumDotValue) {

        int pos = enumDotValue.indexOf(".");

        String enumName = enumDotValue.substring(0, pos);
        String value = enumDotValue.substring(pos + 1);

        Enum enumeratedValue = enumsByName.get(enumName).apply(value);

        return enumeratedValue;
    }


}

You can change

Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)

to

Range("B3:B65536").Copy 
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues

BTW, if you have xls file (excel 2003), you would get an error if your lastrow would be greater 3.

Try to use this code instead:

Sub Get_Data()
    Dim lastrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    With Sheets("DB")
        lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
    End With

    arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
    arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")

    For i = LBound(arr1) To UBound(arr1)
        With Sheets("Sheet1")
             lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
             .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
             Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
        End With
    Next
    Application.CutCopyMode = False
End Sub

Note, above code determines last non empty row on DB sheet in column A (variable lastrowDB). If you need to find lastrow for each destination column in DB sheet, use next modification:

For i = LBound(arr1) To UBound(arr1)
   With Sheets("DB")
       lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
   End With

   ' NEXT CODE

Next

You could also use next approach instead Copy/PasteSpecial. Replace

.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues

with

Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
      .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value

UPDATED: assuming C# 6, the chances are that your case can be expressed as an exception filter. This is the ideal approach from a performance perspective assuming your requirement can be expressed in terms of it, e.g.:

try
{
}
catch ( Web2PDFException ex ) when ( ex.Code == 52 )
{
}

Assuming C# < 6, the most efficient is to catch a specific Exception type and do handling based on that. Any catch-all handling can be done separately

try
{
}
catch ( Web2PDFException ex )
{
}

or

try
{
}
catch ( Web2PDFException ex )
{
}
catch ( Exception ex )
{
}

or (if you need to write a general handler - which is generally a bad idea, but if you're sure it's best for you, you're sure):

 if( err is Web2PDFException)
 {
 }

or (in certain cases if you need to do some more complex type hierarchy stuff that cant be expressed with is)

 if( err.GetType().IsAssignableFrom(typeof(Web2PDFException)))
 {
 }

or switch to VB.NET or F# and use is or Type.IsAssignableFrom in Exception Filters

If you want to break your line because of a long literal string, you can break that string into pieces:

long_string = "a very long string"
print("a very long string")

will be replaced by

long_string = (
  "a "
  "very "
  "long "
  "string"
)
print(
  "a "
  "very "
  "long "
  "string"
)

Output for both print statements:

a very long string

Notice the parenthesis in the affectation.

Notice also that breaking literal strings into pieces allows to use the literal prefix only on parts of the string and mix the delimiters:

s = (
  '''2+2='''
  f"{2+2}"
)

If you want one element with the corresponding one you could do

Enumerable.Range(0, List1.Count).All(x => List1[x] == List2[x]);

That will return true if every item is equal to the corresponding one on the second list

If that's almost but not quite what you want it would help if you elaborated more.

Thanks Friend, i got an answer. This is only possible because of your help. you all give me a ray of hope towards resolving this problem.

Here is the code:

package facebook;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;

public class Facebook {
    public static void main(String args[]){
        WebDriver driver = new FirefoxDriver();
        driver.get("http://www.facebook.com");
        WebElement email= driver.findElement(By.id("email"));
        Actions builder = new Actions(driver);
        Actions seriesOfActions = builder.moveToElement(email).click().sendKeys(email, "[email protected]");
        seriesOfActions.perform();
        WebElement pass = driver.findElement(By.id("pass"));
        WebElement login =driver.findElement(By.id("u_0_b"));
        Actions seriesOfAction = builder.moveToElement(pass).click().sendKeys(pass, "naveench").click(login);
        seriesOfAction.perform();
        driver.
    }    
}

IMO Script - is the kind of instruction that program supposed to run Program - is kind of instruction that hardware supposed to run

Though i guess .NET/JAVA byte codes are scripts by this definition

Although the following is not way to do it in GUI but you can get autoincrementing simply using the IDENTITY datatype(start, increment):

CREATE TABLE "dbo"."TableName"
(
   id int IDENTITY(1,1) PRIMARY KEY NOT NULL,
   name varchar(20),
);

the insert statement should list all columns except the id column (it will be filled with autoincremented value):

INSERT INTO "dbo"."TableName" (name) VALUES ('alpha');
INSERT INTO "dbo"."TableName" (name) VALUES ('beta');

and the result of

SELECT id, name FROM "dbo"."TableName";

will be

id    name
--------------------------
1     alpha
2     beta

Create an integer random between e.g. 1-11 and multiply it by 5. Simple math.

import random
for x in range(20):
  print random.randint(1,11)*5,
print

produces e.g.

5 40 50 55 5 15 40 45 15 20 25 40 15 50 25 40 20 15 50 10

Use WinSCP for file transfer over SSH, putty is only for SSH commands.

The document looks fine to me but I suspect that it contains invisible characters. Open it in a hex editor to check that there really isn't anything before the very first "<". Make sure the spaces in the XML header are spaces. Maybe delete the space before "?>". Check which line breaks are used.

Make sure the document is proper UTF-8. Some windows editors save the document as UTF-16 (i.e. every second byte is 0).

This is commonly referred to as screen scraping, by the way. The library I have used for this is Simple HTML Dom Parser.

You can bridge from String to NSString and convert from CInt to Int like this:

var myint: Int = Int(stringNumb.bridgeToObjectiveC().intValue)

When you run php-cgi.exe from the dos command line, you will get the missing MSVCR110.dll pop up message.

according jdk source code from javasourcecode.org, HashSet use HashMap as its inside implementation, the code about put method of HashSet is below :

public V put(K key, V value) {
        if (key == null)
            return putForNullKey(value);
        int hash = hash(key.hashCode());
        int i = indexFor(hash, table.length);
        for (Entry<K,V> e = table[i]; e != null; e = e.next) {
            Object k;
            if (e.hash == hash && ((k = e.key) == key || key.equals(k))) {
                V oldValue = e.value;
                e.value = value;
                e.recordAccess(this);
                return oldValue;
            }
        }

        modCount++;
        addEntry(hash, key, value, i);
        return null;
    }

The rule is firstly check the hash, then check the reference and then call equals method of the object will be putted in.

I made a mix of the answers here, took the code of @Julian and ideas from the others, seems clearer to me, this is what's left:

fiddle http://jsfiddle.net/wq2Ej/

jquery

//store the element
var $cache = $('.my-sticky-element');

//store the initial position of the element
var vTop = $cache.offset().top - parseFloat($cache.css('marginTop').replace(/auto/, 0));
  $(window).scroll(function (event) {
    // what the y position of the scroll is
    var y = $(this).scrollTop();

    // whether that's below the form
    if (y >= vTop) {
      // if so, ad the fixed class
      $cache.addClass('stuck');
    } else {
      // otherwise remove it
      $cache.removeClass('stuck');
    }
  });

css:

.my-sticky-element.stuck {
    position:fixed;
    top:0;
    box-shadow:0 2px 4px rgba(0, 0, 0, .3);
}

Swift

There are tons and tons of explanations here and around Stack Overflow, but if you are a beginner just trying to get something basic to work, try watching this YouTube tutorial (It's what helped me to finally understand how to do it).

• YouTube tutorial: How to send data through segue (Swift)

Passing data forward to the next View Controller

The following is an example based on the video. The idea is to pass a string from the text field in the First View Controller to the label in the Second View Controller.

Create the storyboard layout in the Interface Builder. To make the segue, you just Control click on the button and drag over to the Second View Controller.

First View Controller

The code for the First View Controller is

import UIKit

class FirstViewController: UIViewController {

    @IBOutlet weak var textField: UITextField!

    // This function is called before the segue
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

        // Get a reference to the second view controller
        let secondViewController = segue.destination as! SecondViewController

        // Set a variable in the second view controller with the String to pass
        secondViewController.receivedString = textField.text!
    }

}

Second View Controller

And the code for the Second View Controller is

import UIKit

class SecondViewController: UIViewController {

    @IBOutlet weak var label: UILabel!

    // This variable will hold the data being passed from the First View Controller
    var receivedString = ""

    override func viewDidLoad() {
        super.viewDidLoad()

        // Used the text from the First View Controller to set the label
        label.text = receivedString
    }

}

Don't forget

• Hook up the outlets for the UITextField and the UILabel.
• Set the first and second View Controllers to the appropriate Swift files in Interface Builder.

Passing data back to the previous View Controller

To pass data back from the second view controller to the first view controller, you use a protocol and a delegate. This video is a very clear walk though of that process:

• YouTube tutorial: iOS Swift Basics Tutorial: Protocols and Delegates But also read this post to make sure you don't get into a strong reference cycle.

The following is an example based on the video (with a few modifications).

Create the storyboard layout in the Interface Builder. Again, to make the segue, you just Control drag from the button to the Second View Controller. Set the segue identifier to showSecondViewController. Also, don't forget to hook up the outlets and actions using the names in the following code.

First View Controller

The code for the First View Controller is

import UIKit

class FirstViewController: UIViewController, DataEnteredDelegate {

    @IBOutlet weak var label: UILabel!

    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "showSecondViewController" {
            let secondViewController = segue.destination as! SecondViewController
            secondViewController.delegate = self
        }
    }

    func userDidEnterInformation(info: String) {
        label.text = info
    }
}

Note the use of our custom DataEnteredDelegate protocol.

Second View Controller and Protocol

The code for the second view controller is

import UIKit

// Protocol used for sending data back
protocol DataEnteredDelegate: AnyObject {
    func userDidEnterInformation(info: String)
}

class SecondViewController: UIViewController {

    // Making this a weak variable, so that it won't create a strong reference cycle
    weak var delegate: DataEnteredDelegate? = nil

    @IBOutlet weak var textField: UITextField!

    @IBAction func sendTextBackButton(sender: AnyObject) {

        // Call this method on whichever class implements our delegate protocol
        delegate?.userDidEnterInformation(info: textField.text!)

        // Go back to the previous view controller
        _ = self.navigationController?.popViewController(animated: true)
    }
}

Note that the protocol is outside of the View Controller class.

That's it. Running the app now, you should be able to send data back from the second view controller to the first.

Also, this might help finding the actual location the btsnoop_hci.log is being saved:

adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"

using

$('title').html("new title");

First off I should point out that css animations would probably work best if you are doing this a lot but I ended getting the desired effect by wrapping .scrollLeft inside .animate

$('.swipeRight').click(function()
{

    $('.swipeBox').animate( { scrollLeft: '+=460' }, 1000);
});

$('.swipeLeft').click(function()
{
    $('.swipeBox').animate( { scrollLeft: '-=460' }, 1000);
});

The second parameter is speed, and you can also add a third parameter if you are using smooth scrolling of some sort.

Firstly, there could be two values that you're referring to:

Underlying Value

If you are asking about the underlying value, which could be any of these types: byte, sbyte, short, ushort, int, uint, long or ulong

Then you can simply cast it to it's underlying type. Assuming it's an int, you can do it like this:

int eValue = (int)enumValue;

However, also be aware of each items default value (first item is 0, second is 1 and so on) and the fact that each item could have been assigned a new value, which may not necessarily be in any order particular order! (Credit to @JohnStock for the poke to clarify).

This example assigns each a new value, and show the value returned:

public enum MyEnum
{
    MyValue1 = 34,
    MyValue2 = 27
}

(int)MyEnum.MyValue2 == 27; // True

Index Value

The above is generally the most commonly required value, and is what your question detail suggests you need, however each value also has an index value (which you refer to in the title). If you require this then please see other answers below for details.

With modern browsers, this is easy without jQuery:

document.getElementById('yourParentDiv').querySelectorAll('[id^="q17_"]');

The querySelectorAll takes a selector (as per CSS selectors) and uses it to search children of the 'yourParentDiv' element recursively. The selector uses ^= which means "starts with".

Note that all browsers released since June 2009 support this.

use "temp" in lieu of "tmp"

"/temp/test.png"

it worked for me after i realized the tmp is a temporary folder that didn't exist on my computer, but my temp was my temporary folder

///

EDIT:

I also created a new folder "tmp" in my C: drive and everything worked perfectly. The book may have missed mentioning that small step

check out http://webchat.freenode.net/?channels=node.js to chat with some of the node.js community

Note

Mutation events have been deprecated since this post was written, and may not be supported by all browsers. Instead, use a mutation observer.

Yes you can. DOM L2 Events module defines mutation events; one of them - DOMAttrModified is the one you need. Granted, these are not widely implemented, but are supported in at least Gecko and Opera browsers.

Try something along these lines:

document.documentElement.addEventListener('DOMAttrModified', function(e){
  if (e.attrName === 'style') {
    console.log('prevValue: ' + e.prevValue, 'newValue: ' + e.newValue);
  }
}, false);

document.documentElement.style.display = 'block';

You can also try utilizing IE's "propertychange" event as a replacement to DOMAttrModified. It should allow to detect style changes reliably.

Arrays.asList() would do the trick here.

String[] words = {"ace", "boom", "crew", "dog", "eon"};   

List<String> wordList = Arrays.asList(words);  

For converting to Set, you can do as below

Set<T> mySet = new HashSet<T>(Arrays.asList(words)); 

win = new BrowserWindow({width: 1000, height: 1000,icon: __dirname + '/logo.png'}); //*.png or *.ico will also work 

in my case it worked !

The ID will work with @ sign in front also, but we have to add one parameter after that. that is null

look like:

@Html.ActionLink("Label Name", "Name_Of_Page_To_Redirect", "Controller", new {@id="Id_Value"}, null)

print "bla: ", $_, "\n" if ($_ = $myvar) =~ s/a/b/g or 1;
