I'm assuming this is for a game or for a fast-responding type of application hence the use of KEYDOWN than KEYPRESS.

Edit: Dang! I stand corrected (thank you Crescent Fresh and David): JQuery (or even rather the underlying DOM hosts) do not expose the detail of the WM_KEYDOWN and of other events. Rather they pre-digest this data and, in the case of keyDown even in JQuery, we get:

• event.keyCode for non-character keys
• event.charCode for character keys

Note that these properties are the UniCode values.
Note, I wasn't able to find an authorititative reference to that in JQuery docs, but many reputable examples on the net refer to these two properties.

The following code, adapted from some java (not javascript) of mine, is therefore totally wrong...

The following will give you the "interesting" parts of the keycode:

  value = e.KeyCode;
  repeatCount = value & 0xFF;
  scanCode = (value >> 16) & 0xFF;  // note we take the "extended bit" deal w/ it later.
  wasDown = ((value & 0x4000) != 0);  // indicate key was readily down (auto-repeat)
  if (scanCode > 127)
      // deal with extended
  else
      // "regular" character

Use double quotes while using BASH variables.

mysql --user="$user" --password="$password" --database="$database" --execute="DROP DATABASE $user; CREATE DATABASE $database;"

BASH doesn't expand variables in single quotes.

I noticed that bash automatically escapes some characters when using auto-complete.

For example, if you have a directory named dir:A, bash will auto-complete to dir\:A

Using this, I runned some experiments using characters of the ASCII table and derived the following lists:

Characters that bash escapes on auto-complete: (includes space)

 !"$&'()*,:;<=>?@[\]^`{|}

Characters that bash does not escape:

#%+-.0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz~

(I excluded /, as it cannot be used in directory names)

Well, why not just add them to your existing character class?

var pattern = /[a-zA-Z0-9&._-]/

If you need to check whether a string consists of nothing but those characters you have to anchor the expression as well:

var pattern = /^[a-zA-Z0-9&._-]+$/

The added ^ and $ match the beginning and end of the string respectively.

Testing for letters, numbers or underscore can be done with \w which shortens your expression:

var pattern = /^[\w&.-]+$/

As mentioned in the comment from Nathan, if you're not using the results from .match() (it returns an array with what has been matched), it's better to use RegExp.test() which returns a simple boolean:

if (pattern.test(qry)) {
    // qry is non-empty and only contains letters, numbers or special characters.
}

Update 2

In case I have misread the question, the below will check if all three separate conditions are met.

if (/[a-zA-Z]/.test(qry) && /[0-9]/.test(qry) && /[&._-]/.test(qry)) {
   // qry contains at least one letter, one number and one special character
}

Plain Javascript regex does not handle Unicode letters.

Do not use [^\w\s], this will remove letters with accents (like àèéìòù), not to mention to Cyrillic or Chinese, letters coming from such languages will be completed removed.

You really don't want remove these letters together with all the special characters. You have two chances:

• Add in your regex all the special characters you don't want remove,
  for example: [^èéòàùì\w\s].
• Have a look at xregexp.com. XRegExp adds base support for Unicode matching via the \p{...} syntax.

var str = "????::: résd,$%& adùf"
var search = XRegExp('([^?<first>\\pL ]+)');
var res = XRegExp.replace(str, search, '',"all");

console.log(res); // returns "????::: resd,adf"
console.log(str.replace(/[^\w\s]/gi, '') ); // returns " rsd adf"
console.log(str.replace(/[^\wèéòàùì\s]/gi, '') ); // returns " résd adùf"

The problem is the charset that is being used by apache to serve the pages. I work with Linux, so I don't know anything about XAMPP. I had the same problem too, what I did to solve the problem was to add the charset to the charset config file (It is commented by default).

In my case I have it in /etc/apache2/conf.d/charset but, since you're using Windows the location is different. So I'm giving you this like an idea of how to solve it.

At the end, my charset config file is like this:

# Read the documentation before enabling AddDefaultCharset.
# In general, it is only a good idea if you know that all your files
# have this encoding. It will override any encoding given in the files
# in meta http-equiv or xml encoding tags.

AddDefaultCharset UTF-8

I hope it helps.

So I try htmlspecialchars() or htmlentities() which outputs <p>Résumé<p> and the browser renders <p>Résumé<p>.

If you've got it working where it displays Résumé with <p></p> tags around it, then just don't convert the paragraph, only your string. Then the paragraph will be rendered as HTML and your string will be displayed within.

From RFC 1738 on which characters are allowed in URLs:

Only alphanumerics, the special characters "$-_.+!*'(),", and reserved characters used for their reserved purposes may be used unencoded within a URL.

The reserved characters are ";", "/", "?", ":", "@", "=" and "&", which means you would need to URL encode them if you wish to use them.

It has the last status code (exit value) of a command.

I faced the same error with:

import codecs as cd
f=cd.open(filePath,'r','ISO-8859-1')

I solved the problem by changing the encoding to utf-16

f=cd.open(filePath,'r','utf-16')

Use a single backspace after each character printf("hello wor\bl\bd\n");

You don't escape quotes in regular expressions

this.Vals.replace(/["']/g, "")

Try vi with the -b option, this will show special end of line characters (I typically use it to see windows line endings in a txt file on a unix OS)

But if you want a scripted solution obviously vi wont work so you can try the -f or -e options with grep and pipe the result into sed or awk. From grep man page:

Matcher Selection -E, --extended-regexp Interpret PATTERN as an extended regular expression (ERE, see below). (-E is specified by POSIX.)

   -F, --fixed-strings
          Interpret PATTERN as a list of fixed strings, separated by newlines, any of which is to be matched.  (-F is specified
          by POSIX.)

var specialChars = "<>@!#$%^&*()_+[]{}?:;|'\"\\,./~`-="
var check = function(string){
    for(i = 0; i < specialChars.length;i++){
        if(string.indexOf(specialChars[i]) > -1){
            return true
        }
    }
    return false;
}

if(check($('#Search').val()) == false){
    // Code that needs to execute when none of the above is in the string
}else{
    alert('Your search string contains illegal characters.');
}

The original request has been answered already.

However, I am posting the below answer for those who might be looking for generic transliteration code to transliterate any charset to Latin/English in Java.

Naive meaning of tranliteration: Translated string in it's final form/target charset sounds like the string in it's original form. If we want to transliterate any charset to Latin(English alphabets), then ICU4(ICU4J library in java ) will do the job.

Here is the code snippet in java:

    import com.ibm.icu.text.Transliterator; //ICU4J library import

    public static String TRANSLITERATE_ID = "NFD; Any-Latin; NFC";
    public static String NORMALIZE_ID = "NFD; [:Nonspacing Mark:] Remove; NFC";

    /**
    * Returns the transliterated string to convert any charset to latin.
    */
    public static String transliterate(String input) {
        Transliterator transliterator = Transliterator.getInstance(TRANSLITERATE_ID + "; " + NORMALIZE_ID);
        String result = transliterator.transliterate(input);
        return result;
    }

you can use html entity as •

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

I know it's an old question, but it's easy to check this out. Just create a folder with a bunch of dummy files whose names are each character on the keyboard. Of course, you can't really use \ | / : * ? " < > and leading and trailing blanks are a terrible idea.

If you do this, and it looks like no one did, you find that the Windows sort order for the FIRST character is 1. Special characters 2. Numbers 3. Letters

But for subsequent characters, it seems to be 1. Numbers 2. Special characters 3. Letters

Numbers are kind of weird, thanks to the "Improvements" made after the Y2K non-event. Special characters you would think would sort in ASCII order, but there are exceptions, notably the first two, apostrophe and dash, and the last two, plus and equals. Also, I have heard but not actually seen something about dashes being ignored. That is, in fact, NOT my experience.

So, ShxFee, I assume you meant the sort should be ascending, not descending, and the top-most (first) character in the sort order for the first character of the name is the apostrophe.

As NigelTouch said, special characters do not sort to ASCII, but my notes above specify exactly what does and does not sort in normal ASCII order. But he is certainly wrong about special characters always sorting first. As I noted above, that only appears to be true for the first character of the name.

You are most likely escaping the SQL string, similar to:

SELECT * FROM `table` WHERE `column` = 'Here's a syntax error!'

You need to escape quotes, like follows:

SELECT * FROM `table` WHERE `column` = 'Here\'s a syntax error!'

mysql_real_escape_string() handles this for you.

similar to R0byn's experience, i was experimenting with a Powerpoint slide presentation and dumped out the main body of text on the slide, finding that all the places where one would typically find carriage return (ASCII 13/0x0d/^M) or line feed/new line (ASCII 10/0x0a/^J) characters, it uses vertical tab (ASCII 11/0x0b/^K) instead, presumably for the exact reason that dan04 described above for Word: to serve as a "newline" while staying within the same paragraph. good question though as i totally thought this character would be as useless as a teletype terminal today.

You ca try this:

ul { list-style: none;}

li { position: relative;}

li:before {
    position: absolute;  
    top: 8px;  
    margin: 8px 0 0 -12px;    
    vertical-align: middle;
    display: inline-block;
    width: 4px;
    height: 4px;
    background: #ccc;
    content: "";
}

It worked for me, thanks to this post.

This method checks if a String contains a special character (based on your definition).

/**
 *  Returns true if s contains any character other than 
 *  letters, numbers, or spaces.  Returns false otherwise.
 */

public boolean containsSpecialCharacter(String s) {
    return (s == null) ? false : s.matches("[^A-Za-z0-9 ]");
}

You can use the same logic to count special characters in a string like this:

/**
 *  Counts the number of special characters in s.
 */

 public int getSpecialCharacterCount(String s) {
     if (s == null || s.trim().isEmpty()) {
         return 0;
     }
     int theCount = 0;
     for (int i = 0; i < s.length(); i++) {
         if (s.substring(i, 1).matches("[^A-Za-z0-9 ]")) {
             theCount++;
         }
     }
     return theCount;
 }

Another approach is to put all the special chars in a String and use String.contains:

/**
 *  Counts the number of special characters in s.
 */

 public int getSpecialCharacterCount(String s) {
     if (s == null || s.trim().isEmpty()) {
         return 0;
     }
     int theCount = 0;
     String specialChars = "/*!@#$%^&*()\"{}_[]|\\?/<>,.";
     for (int i = 0; i < s.length(); i++) {
         if (specialChars.contains(s.substring(i, 1))) {
             theCount++;
         }
     }
     return theCount;
 }

NOTE: You must escape the backslash and " character with a backslashes.

The above are examples of how to approach this problem in general.

For your exact problem as stated in the question, the answer by @LanguagesNamedAfterCoffee is the most efficient approach.

We eventually found the answer to this.

Excel will only respect the escaping of commas and speech marks if the column value is NOT preceded by a space. So generating the file without spaces like this...

Reference,Title,Description
1,"My little title","My description, which may contain ""speech marks"" and commas."
2,"My other little title","My other description, which may also contain ""speech marks"" and commas."

... fixed the problem. Hope this helps someone!

dot (.) may not be considered special. I have added an OR condition to Mozfet's & Seagull's answer:

function isNumber (text) {
      reg = new RegExp('[0-9]+$');
      if(text) {
        return reg.test(text);
      }
      return false;
    }

function removeSpecial (text) {
  if(text) {
    var lower = text.toLowerCase();
    var upper = text.toUpperCase();
    var result = "";
    for(var i=0; i<lower.length; ++i) {
      if(isNumber(text[i]) || (lower[i] != upper[i]) || (lower[i].trim() === '') || (lower[i].trim() === '.')) {
        result += text[i];
      }
    }
    return result;
  }
  return '';
}

\ => \\ and " => \"

so Replace("\\\"","")

With Unicode we can do it easily,but if want to change color of bullet, I tried with colored bullet image and set it as drawable left and it worked

<TextView     
    android:text="Hello bullet"
    android:drawableLeft="@drawable/bulleticon" >
</TextView>

To replace special characters, space and convert to lower case

$(document).ready(function (){
  $(document).on("keyup", "#Id", function () {
  $("#Id").val($("#Id").val().replace(/[^a-z0-9\s]/gi, '').replace(/[_\s]/g, '').toLowerCase());
 }); 
});

Here is the code to clean file name in python.

import unicodedata

def clean_name(name, replace_space_with=None):
    """
    Remove invalid file name chars from the specified name

    :param name: the file name
    :param replace_space_with: if not none replace space with this string
    :return: a valid name for Win/Mac/Linux
    """

    # ref: https://en.wikipedia.org/wiki/Filename
    # ref: https://stackoverflow.com/questions/4814040/allowed-characters-in-filename
    # No control chars, no: /, \, ?, %, *, :, |, ", <, >

    # remove control chars
    name = ''.join(ch for ch in name if unicodedata.category(ch)[0] != 'C')

    cleaned_name = re.sub(r'[/\\?%*:|"<>]', '', name)
    if replace_space_with is not None:
        return cleaned_name.replace(' ', replace_space_with)
    return cleaned_name

Potential answer for SQL Server

Interesting I just ran a test using LinqPad with SQL Server which should be just running Linq to SQL underneath and it generates the following SQL statement.

Records .Where(r => r.Name.Contains("lkjwer--_~[]"))

-- Region Parameters
DECLARE @p0 VarChar(1000) = '%lkjwer--~_~~~[]%'
-- EndRegion
SELECT [t0].[ID], [t0].[Name]
FROM [RECORDS] AS [t0]
WHERE [t0].[Name] LIKE @p0 ESCAPE '~'

So I haven't tested it yet but it looks like potentially the ESCAPE '~' keyword may allow for automatic escaping of a string for use within a like expression.

select concat('''','abc','''')

Even your question is answered, still i want tell more entities same like this. These are html entities, so in android you will write them like:

public boolean isValidName(String name)
{
    String specialCharacters=" !#$%&'()*+,-./:;<=>?@[]^_`{|}~0123456789";
    String str2[]=name.split("");
    int count=0;
    for (int i=0;i<str2.length;i++)
    {
        if (specialCharacters.contains(str2[i]))
        {
            count++;
        }
    }       

    if (name!=null && count==0 )
    {
        return true;
    }
    else
    {
        return false;
    }
}

In short \r has ASCII value 13 (CR) and \n has ASCII value 10 (LF). Mac uses CR as line delimiter (at least, it did before, I am not sure for modern macs), *nix uses LF and Windows uses both (CRLF).

To set Conditional Formatting for an ENTIRE ROW based on a single cell you must ANCHOR that single cell's column address with a "$", otherwise Excel will only get the first column correct. Why?

Because Excel is setting your Conditional Format for the SECOND column of your row based on an OFFSET of columns. For the SECOND column, Excel has now moved one column to the RIGHT of your intended rule cell, examined THAT cell, and has correctly formatted column two based on a cell you never intended.

Simply anchor the COLUMN portion of your rule cell's address with "$", and you will be happy

For example: You want any row of your table to highlight red if the last cell of that row does not equal 1.

Select the entire table (but not the headings) "Home" > "Conditional Formatting" > "Manage Rules..." > "New Rule" > "Use a formula to determine which cells to format"

Enter: "=$T3<>1" (no quotes... "T" is the rule cell's column, "3" is its row) Set your formatting Click Apply.

Make sure Excel has not inserted quotes into any part of your formula... if it did, Backspace/Delete them out (no arrow keys please).

Conditional Formatting should be set for the entire table.

in fact the Is is really good, since to the developpers, you may want to override the operator ==, to compare with the value. say you have a class A, operator == of A is to compare some of the field of A to the parameter. then you will be in trouble in c# to verify whether the object of A is null with following code,

    A a = new A();
...
    if (a != null)
it will totally wrong, you always need to use if((object)a != null)
but in vb.net you cannot write in this way, you always need to write
    if not a is nothing then
or
    if a isnot nothing then

which just as Christian said, vb.net does not 'expected' anything.

Here's a very naive implementation I'm using. It's non-destructive and also makes sure not to duplicate entires.

Array.prototype.contains = function(elem) {
    return(this.indexOf(elem) > -1);
};

Array.prototype.intersect = function( array ) {
    // this is naive--could use some optimization
    var result = [];
    for ( var i = 0; i < this.length; i++ ) {
        if ( array.contains(this[i]) && !result.contains(this[i]) )
            result.push( this[i] );
    }
    return result;
}

actually this depends on what DBMS you are using but in regular SQL convert(varchar,DateColumn,101) will change the DATETIME format to date (one day)

so:

SELECT 
    sum(amount) 
FROM 
    sales 
GROUP BY 
    convert(varchar,created,101)

the magix number 101 is what date format it is converted to

If you're using maven I would do something like this:

Being production your default profile:

<properties>
    <activeProfile>production</activeProfile>
</properties>

And as an example of other profiles:

<profiles>
    <!--Your default profile... selected if none specified-->
    <profile>
        <id>production</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <activeProfile>production</activeProfile>
        </properties>
    </profile>

    <!--Profile 2-->
    <profile>
        <id>development</id>
        <properties>
            <activeProfile>development</activeProfile>
        </properties>
    </profile>

    <!--Profile 3-->
    <profile>
        <id>otherprofile</id>
        <properties>
            <activeProfile>otherprofile</activeProfile>
        </properties>
    </profile>
<profiles>

In your application.properties you'll have to set:

spring.profiles.active=@activeProfile@

This works for me every time, hope it solves your problem.

Try this:

INSERT INTO `center_course_fee` (`fk_course_id`,`fk_center_code`,`course_fee`) VALUES ('69', '4920153', '6000') ON DUPLICATE KEY UPDATE `course_fee` = '6000';

You can do it manually. (I know, that that isn't great solution, but..) use while loop till the result hasn't a value

kickOff().then(function(result) {
   while(true){
       if (result === undefined) continue;
       else {
            $("#output").append(result);
            return;
       }
   }
});

It's called correlated subquery. It has it's uses.

The readr package will fix this issue.

install.packages('readr')
library(readr)
readr::read_csv('yourfile.csv')

If you have more than one button, then you can do the following.

<div class="center-block" style="max-width:400px">
  <a href="#" class="btn btn-success">Accept</a>
  <a href="#" class="btn btn-danger"> Reject</a>
</div>

Let's Encrypt is a free, automated, and open certificate authority made by the Internet Security Research Group (ISRG). It is sponsored by well-known organisations such as Mozilla, Cisco or Google Chrome. All modern browsers are compatible and trust Let's Encrypt.

All certificates are free (even wildcard certificates)! For security reasons, the certificates expire pretty fast (after 90 days). For this reason, it is recommended to install an ACME client, which will handle automatic certificate renewal.

There are many clients you can use to install a Let's Encrypt certificate:

Let’s Encrypt uses the ACME protocol to verify that you control a given domain name and to issue you a certificate. To get a Let’s Encrypt certificate, you’ll need to choose a piece of ACME client software to use. - https://letsencrypt.org/docs/client-options/

You can also use common table expressions to store temporary datasets. They are more elegant and adhoc friendly:

WITH userData (name, oldlocation)
AS
(
  SELECT name, location 
  FROM   myTable    INNER JOIN 
         otherTable ON ...
  WHERE  age>30
)
SELECT * 
FROM   userData -- you can also reuse the recordset in subqueries and joins

you can make an array like:

s = np.arange(0, len(a), 1)

then shuffle it:

np.random.shuffle(s)

now use this s as argument of your arrays. same shuffled arguments return same shuffled vectors.

x_data = x_data[s]
x_label = x_label[s]

For general case of syntax you can look at annex A of the ANSI C standard.

In the Backus-Naur form from there, you can see that typedef has the type storage-class-specifier.

In the type declaration-specifiers you can see that you can mix many specifier types, the order of which does not matter.

For example, it is correct to say,

long typedef long a;

to define the type a as an alias for long long. So , to understand the typedef on the exhaustive use you need to consult some backus-naur form that defines the syntax (there are many correct grammars for ANSI C, not only that of ISO).

When you use typedef to define an alias for a function type you need to put the alias in the same place where you put the identifier of the function. In your case you define the type FunctionFunc as an alias for a pointer to function whose type checking is disabled at call and returning nothing.

Try using: $_SERVER['SERVER_NAME'];

I used it to echo the base url of my site to link my css.

<link href="//<?php echo $_SERVER['SERVER_NAME']; ?>/assets/css/your-stylesheet.css" rel="stylesheet" type="text/css">

Hope this helps!

You must link an event in your onClick. Additionally, the click function must receive the event. See the example

export default function Component(props) {

    function clickEvent (event, variable){
        console.log(variable);
    }

    return (
        <div>
            <IconButton
                key="close"
                aria-label="Close"
                color="inherit"
                onClick={e => clickEvent(e, 10)}
            >
        </div>
    )
}

POSIX is a standard for operating systems that was supposed to make it easier to write cross-platform software. It's an especially big deal in the world of Unix.

   self.tableView.tableHeaderView = segmentedControl; 

If you want it to obey your width and height properly though enclose your segmentedControl in a UIView first as the tableView likes to mangle your view a bit to fit the width.

You can try with this. You have this error because we can not divide by 'zero' (0) value. So we want to validate before when we do calculations.

if ($itemCost != 0 && $itemCost != NULL && $itemQty != 0 && $itemQty != NULL) 
{
    $diffPricePercent = (($actual * 100) / $itemCost) / $itemQty;
}

And also we can validate POST data. Refer following

$itemQty = isset($_POST['num1']) ? $_POST['num1'] : 0;

$itemCost = isset($_POST['num2']) ? $_POST['num2'] : 0;

$itemSale = isset($_POST['num3']) ? $_POST['num3'] : 0;

$shipMat = isset($_POST['num4']) ? $_POST['num4'] : 0;

In my notebook, Dell Latitude E4310, the Ctrl+F12 keys do the job.

            @Override
            public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
                final HttpServletResponse response = (HttpServletResponse) res;
                response.setHeader("Access-Control-Allow-Origin", "*");
                response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
                response.setHeader("Access-Control-Allow-Headers", "Authorization, Content-Type, enctype");
                response.setHeader("Access-Control-Max-Age", "3600");
                if (HttpMethod.OPTIONS.name().equalsIgnoreCase(((HttpServletRequest) req).getMethod())) {
                    response.setStatus(HttpServletResponse.SC_OK);
                } else {
                    chain.doFilter(req, res);

Linux users can find the locations of all the installed packages like this:

pip list | xargs -exec pip show

ALTER TABLE table_name DROP PRIMARY KEY,ADD PRIMARY KEY (col_name1, col_name2);

inside your save button click add this code :

$("#btnSave").click(function (e) {
  e.preventDefault();
  swal("Are you sure?", {
    buttons: {
      yes: {
        text: "Yes",
        value: "yes"
      },
      no: {
        text: "No",
        value: "no"
      }
    }
  }).then((value) => {
    if (value === "yes") {
      // Add Your Custom Code for CRUD
    }
    return false;
  });
});

Within your onDropDownChange handler, just make a jQuery AJAX call, passing in any data you need to pass up to your URL. You can handle successful and failure calls with the success and error options. In the success option, use the data contained in the data argument to do whatever rendering you need to do. Remember these are asynchronous by default!

function onDropDownChange(e) {
    var url = '/Home/Index/' + e.value;
    $.ajax({
      url: url,
      data: {}, //parameters go here in object literal form
      type: 'GET',
      datatype: 'json',
      success: function(data) { alert('got here with data'); },
      error: function() { alert('something bad happened'); }
    });
}

jQuery's AJAX documentation is here.

Sessions Step By Step

1. Defining session before everything, No output should be before that, NO OUTPUT

   <?php
   session_start();
   ?>
   

2. Set your session inside a page and then you have access in that page. For example this is page 1.php

   <?php
      //This is page 1 and then we will use session that defined from this page:
       session_start();
       $_SESSION['email']='[email protected]';
   ?>
   

3. Using and Getting session in 2.php

    <?php
   
   //In this page I am going to use session:
   
     session_start();
     if($_SESSION['email']){
     echo 'Your Email Is Here!  :) ';
     }
    ?>
   

NOTE: Comments don't have output.

This works for me: Ctrl+Shift+V

On my Galaxy S v.2.3.3 Shared Preferences are not stored in:/data/data/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml

but are now located in: /dbdata/databases/YOUR_PACKAGE_NAME/shared_prefs/YOUR_PREFS_NAME.xml

I believe they changed this in 2.3

First backup the old database called HRMS and edit the script file with replace the word HRMS to SUNHRM. After this step import the database file to the mysql

You could require the type to be a reference type :

 private static T ReadData<T>(XmlReader reader, string value) where T : class
 {
     reader.MoveToAttribute(value);
     object readData = reader.ReadContentAsObject();
     return (T)readData;
 }

And then do another that uses value types and TryParse...

 private static T ReadDataV<T>(XmlReader reader, string value) where T : struct
 {
     reader.MoveToAttribute(value);
     object readData = reader.ReadContentAsObject();
     int outInt;
     if(int.TryParse(readData, out outInt))
        return outInt
     //...
 }

As far as I know, and I cant verify it now, you cannot stop remote services with the Stop-Service cmdlet or with .Net, it is not supported.

Yes it works, but it stopes the service on your local machine, not on the remote computer.

Now, if the above is correct, without remoting or wmi enabled, you could set a scheduled job on the remote system, using AT, that runs Stop-Service locally.

var fs = require("fs");

function readFileLineByLine(filename, processline) {
    var stream = fs.createReadStream(filename);
    var s = "";
    stream.on("data", function(data) {
        s += data.toString('utf8');
        var lines = s.split("\n");
        for (var i = 0; i < lines.length - 1; i++)
            processline(lines[i]);
        s = lines[lines.length - 1];
    });

    stream.on("end",function() {
        var lines = s.split("\n");
        for (var i = 0; i < lines.length; i++)
            processline(lines[i]);
    });
}

var linenumber = 0;
readFileLineByLine(filename, function(line) {
    console.log(++linenumber + " -- " + line);
});

You said you are using process.on('uncaughtException', callback);
Where are you executing this statement? Is it within the callback passed to http.createServer?
If yes, different copy of the same callback will get attached to the uncaughtException event upon each new request, because the function (req, res) { ... } gets executed everytime a new request comes in and so will the statement process.on('uncaughtException', callback);
Note that the process object is global to all your requests and adding listeners to its event everytime a new request comes in will not make any sense. You might not want such kind of behaviour.
In case you want to attach a new listener for each new request, you should remove all previous listeners attached to the event as they no longer would be required using:
process.removeAllListeners('uncaughtException');

Using white-space: pre-line allows you to input the text directly in the HTML with line breaks without having to use \n

If you use the innerText property of the element via JavaScript on a non-pre element e.g. a <div>, the \n values will be replaced with <br> in the DOM by default

• innerText: replaces \n with <br>
• innerHTML, textContent: require the use of styling white-space

It depends on how your applying the text, but there are a number of options

const node = document.createElement('div');
node.innerText = '\n Test \n One '

If using Sublime Text 3:

• Go to Preferences -> Settings
• Under Preferences.sublime-settings—User add "esversion": 6

I like to do this with sed. In you case:

for x in DET01-*.dat; do
    echo $x | sed -r 's/DET01-ABC-(.+)\.dat/mv -v "\0" "DET01-XYZ-\1.dat"/'
done | sh -e

It is best to omit the "sh -e" part first to see what will be executed.

jQuery Ajax loader is not working well when you call two APIs simultaneously. To resolve this problem you have to call the APIs one by one using the isAsync property in Ajax setting. You also need to make sure that there should not be any error in the setting. Otherwise, the loader will not work. E.g undefined content-type, data-type for POST/PUT/DELETE/GET call.

• Method 1 has slightly better support - you have to set the width OR height of image!
• With the prefixes method 2 also has decent support ( from ie9 up ) - Method 2 has no support on Opera mini!
• Method 3 uses two wrappers - can overflow width AND height.
• Method 4 uses a double image ( one as placeholder ) this gives some extra bandwidth overhead, but even better crossbrowser support.

Method 1 and 3 don't seem to work with Firefox

I had a similar problem . For this you can use a Hashmap which takes "string" and "object" as shown in code below:

/** stores the image database icons */
public static int[] imageIconDatabase = { R.drawable.ball,
        R.drawable.catmouse, R.drawable.cube, R.drawable.fresh,
        R.drawable.guitar, R.drawable.orange, R.drawable.teapot,
        R.drawable.india, R.drawable.thailand, R.drawable.netherlands,
        R.drawable.srilanka, R.drawable.pakistan,

};
private void initializeImageList() {
    // TODO Auto-generated method stub
    for (int i = 0; i < imageIconDatabase.length; i++) {
        map = new HashMap<String, Object>();

        map.put("Name", imageNameDatabase[i]);
        map.put("Icon", imageIconDatabase[i]);
    }

}

For a project structure like

project_name/src/main/java/Main_File.class

in the file build.gradle, add the following line

mainClassName = 'Main_File'

If you use the service wrapper provided in Elasticsearch's Github repository, found at https://github.com/elasticsearch/elasticsearch-servicewrapper, then the conf file at elasticsearch-servicewrapper / service / elasticsearch.conf controls memory settings. At the top of elasticsearch.conf is a parameter:

set.default.ES_HEAP_SIZE=1024

Just reduce this parameter, say to "set.default.ES_HEAP_SIZE=512", to reduce Elasticsearch's allotted memory.

Note that if you use the elasticsearch-wrapper, the ES_HEAP_SIZE provided in elasticsearch.conf OVERRIDES ALL OTHER SETTINGS. This took me a bit to figure out, since from the documentation, it seemed that heap memory could be set from elasticsearch.yml.

If your service wrapper settings are set somewhere else, such as at /etc/default/elasticsearch as in James's example, then set the ES_HEAP_SIZE there.

Try this:

using System.Data.Linq;
var result = from i in list
             where i.age > 45
             select i;

Using lambda expression please use this Statement:

var result = list.where(i => i.age > 45);

if a parent container contains transform this could happen. try commenting them

-webkit-transform: translate3d(0,0,0);
transform: translate3d(0,0,0);

I find a good way of achieving this at Remove browse button from input=file.

The rationale behind this solution is that it creates a transparent input=file control and creates an layer visible to the user below the file control. The z-index of the input=file will be higher than the layer.

With this, it appears that the layer is the file control itself. But actually when you clicks on it, the input=file is the one clicked and the dialog for choosing file will appear.

x & 1 is equivalent to x % 2.

x >> 1 is equivalent to x / 2

So, these things are basically the result and remainder of divide by two.

If you had the problem, opened SDK manager, installed the requested updates, returned to Android Studio and had the problem again, IT IS RECOMMENDED TO RESTART ANDROID STUDIO befor trying anything else.

Gradle will run automatically and chances are that your problem will be over. You will very possibly be told install the appropriate SDK TOOLS package, which is found in your SDK MANAGER under the second tab (sdk's are not the same as sdk tools, they are complementary packages).

You don't even need to hunt the tools package, if you click on the link under the error message, Android Studio should call SDK Manager to install the package automatically.

Restart Android Studio again and you should be up and running much faster than if you attempted workarounds.

RULE OF THUMB> restart your application before messing with options and configurations.

Swift 3.0

i had the same problem, i found on the documentation Apple this solution.

let numbers = [1, 2, 3, 4]
let addTwo: (Int, Int) -> Int = { x, y in x + y }
let numberSum = numbers.reduce(0, addTwo)
// 'numberSum' == 10

But, in my case i had a list of object, then i needed transform my value of my list:

let numberSum = self.list.map({$0.number_here}).reduce(0, { x, y in x + y })

this work for me.

Use the SelectMany extension method

list = listOfList.SelectMany(x => x).ToList();

C++ programs are translated to assembly programs during the generation of machine code from the source code. It would be virtually wrong to say assembly is slower than C++. Moreover, the binary code generated differs from compiler to compiler. So a smart C++ compiler may produce binary code more optimal and efficient than a dumb assembler's code.

However I believe your profiling methodology has certain flaws. The following are general guidelines for profiling:

1. Make sure your system is in its normal/idle state. Stop all running processes (applications) that you started or that use CPU intensively (or poll over the network).
2. Your datasize must be greater in size.
3. Your test must run for something more than 5-10 seconds.
4. Do not rely on just one sample. Perform your test N times. Collect results and calculate the mean or median of the result.

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

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

series1.csv

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

series2.csv

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

Source Code

public class CSVChartRows {

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

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

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

To indicate a missing file/resource and serve a 404 page, you need not redirect. In the same request you must generate the response with the status code set to 404 and the content of your 404 HTML page as response body. Here is the sample code to demonstrate this in Node.js.

var http = require('http'),
    fs = require('fs'),
    util = require('util'),
    url = require('url');

var server = http.createServer(function(req, res) {
    if(url.parse(req.url).pathname == '/') {
        res.writeHead(200, {'content-type': 'text/html'});
        var rs = fs.createReadStream('index.html');
        util.pump(rs, res);
    } else {
        res.writeHead(404, {'content-type': 'text/html'});
        var rs = fs.createReadStream('404.html');
        util.pump(rs, res);
    }
});

server.listen(8080);

Cohesion is an indication of how related and focused the responsibilities of an software element are.

Coupling refers to how strongly a software element is connected to other elements.

The software element could be class, package, component, subsystem or a system. And while designing the systems it is recommended to have software elements that have High cohesion and support Low coupling.

Low cohesion results in monolithic classes that are difficult to maintain, understand and reduces re-usablity. Similarly High Coupling results in classes that are tightly coupled and changes tend not be non-local, difficult to change and reduces the reuse.

We can take a hypothetical scenario where we are designing an typical monitor-able ConnectionPool with the following requirements. Note that, it might look too much for a simple class like ConnectionPool but the basic intent is just to demonstrate low coupling and high cohesion with some simple example and I think should help.

1. support getting a connection
2. release a connection
3. get stats about connection vs usage count
4. get stats about connection vs time
5. Store the connection retrieval and release information to a database for reporting later.

With low cohesion we could design a ConnectionPool class by forcefully stuffing all this functionality/responsibilities into a single class as below. We can see that this single class is responsible for connection management, interacting with database as well maintaining connection stats.

With high cohesion we can assign these responsibility across the classes and make it more maintainable and reusable.

To demonstrate Low coupling we will continue with the high cohesion ConnectionPool diagram above. If we look at the above diagram although it supports high cohesion, the ConnectionPool is tightly coupled with ConnectionStatistics class and PersistentStore it interacts with them directly. Instead to reduce the coupling we could introduce a ConnectionListener interface and let these two classes implement the interface and let them register with ConnectionPool class. And the ConnectionPool will iterate through these listeners and notify them of connection get and release events and allows less coupling.

Note/Word or Caution: For this simple scenario it may look like an overkill but if we imagine a real-time scenario where our application needs to interact with multiple third party services to complete a transaction: Directly coupling our code with the third party services would mean that any changes in the third party service could result in changes to our code at multiple places, instead we could have Facade that interacts with these multiple services internally and any changes to the services become local to the Facade and enforce low coupling with the third party services.

I had similar error while trying to start httpd service for openstack train installation in RHEL 7.5 too.

Solution: It got resolved by disabling SElinux.

Why using selector as the root tag? selector is used for applying multiple alternate drawables for different states of the view, so in this case, there is no need for selector.

Try the following code.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Background Color -->
    <solid android:color="#ffffff" />

    <!-- Border Color -->
    <stroke android:width="1dp" android:color="#ff9900" />

    <!-- Round Corners -->
    <corners android:radius="5dp" />

</shape>

Also It's worth mentioning that all color entries support alpha channel as well, meaning that you can have transparent or semi-transparent colors. For example #RRGGBBAA.

TL;DR Make a copy or alias of your python.exe with name python2.7.exe

My python 2.7 was installed as

D:\app\Python27\python.exe

I always got this error no matter how I set (and verified) PYTHON env variable:

gyp ERR! stack Error: Can't find Python executable "python2.7", you can set the PYTHON env variable.
gyp ERR! stack     at failNoPython (C:\Program Files\nodejs\node_modules\npm\node_modules\node-gyp\lib\configure.js:103:14)

The reason for this was that in node-gyp's configure.js the python executable was resolved like:

var python = gyp.opts.python || process.env.PYTHON || 'python'

And it turned out that gyp.opts.python had value 'python2.7' thus overriding process.env.PYTHON.

I resolved this by creating an alias for python.exe executable with name node-gyp was looking for:

D:\app\Python27>mklink python2.7.exe python.exe

You need admin rights for this operation.

import CoreLocation
import UIKit

class ViewController: UIViewController, CLLocationManagerDelegate {

    var locationManager: CLLocationManager!

    override func viewDidLoad() {
        super.viewDidLoad()
        locationManager = CLLocationManager()
        locationManager.delegate = self
        locationManager.requestWhenInUseAuthorization()
    } 

    func locationManager(_ manager: CLLocationManager, didChangeAuthorization status: CLAuthorizationStatus) {
        if status != .authorizedWhenInUse {return}
        locationManager.desiredAccuracy = kCLLocationAccuracyBest
        locationManager.startUpdatingLocation()
        let locValue: CLLocationCoordinate2D = manager.location!.coordinate
        print("locations = \(locValue.latitude) \(locValue.longitude)")
    }
}

Because the call to requestWhenInUseAuthorization is asynchronous, the app calls the locationManager function after the user has granted permission or rejected it. Therefore it is proper to place your location getting code inside that function given the user granted permission. This is the best tutorial on this I have found on it.

Try this

      $('document').ready(function(){
         window.setTimeout('test()',time in milliseconds);
      });

      function test(){

      $('#divid').hide();

      } 

subprocess.Popen takes a cwd argument to set the Current Working Directory; you'll also want to escape your backslashes ('d:\\test\\local'), or use r'd:\test\local' so that the backslashes aren't interpreted as escape sequences by Python. The way you have it written, the \t part will be translated to a tab.

So, your new line should look like:

subprocess.Popen(r'c:\mytool\tool.exe', cwd=r'd:\test\local')

To use your Python script path as cwd, import os and define cwd using this:

os.path.dirname(os.path.realpath(__file__))

The preferred method for passing an array of values to a stored procedure in SQL server is to use table valued parameters.

First you define the type like this:

CREATE TYPE UserList AS TABLE ( UserID INT );

Then you use that type in the stored procedure:

create procedure [dbo].[get_user_names]
@user_id_list UserList READONLY,
@username varchar (30) output
as
select last_name+', '+first_name 
from user_mstr
where user_id in (SELECT UserID FROM @user_id_list)

So before you call that stored procedure, you fill a table variable:

DECLARE @UL UserList;
INSERT @UL VALUES (5),(44),(72),(81),(126)

And finally call the SP:

EXEC dbo.get_user_names @UL, @username OUTPUT;

In some cases, such as when you're outside The Loop, you may need to use get_queried_object_id() instead of get_the_ID().

$postID = get_queried_object_id();

This is an old bug, but I encountered it today on a web service which had barely been altered since being created via "New \ Project.."

For me, this issue was caused by the "IService.cs" file containing the following:

<%@ ServiceHost Language="C#" Debug="true" Service="JSONWebService.Service1.svc" CodeBehind="Service1.svc.cs" %>

Notice the value in the Service attribute contains ".svc" at the end.

This shouldn't be there.

Removing those 4 characters resolved this issue.

<%@ ServiceHost Language="C#" Debug="true" Service="JSONWebService.Service1" CodeBehind="Service1.svc.cs" %>

Note that you need to open this file from outside of Visual Studio.

Visual Studio shows one file, Service1.cs in the Solution Explorer, but that only lets you alter Service1.svc.cs, not the Service1.svc file.

If you have a relatively- (or otherwise-) positioned div you can center something inside it with margin:auto

Vertical centering is a bit tricker, but possible.

Something is wrong with your Python/Computer.

a = iter(list(range(10)))
for i in a:
   print(i)
   next(a)

>>> 
0
2
4

8

Works like expected.

Tested in Python 2.7 and in Python 3+ . Works properly in both

for large data set and multiple value drop down it is better to use ng-options rather than ng-repeat.

ng-repeat is slow because it loops over all coming values but ng-options simply display to the select option.

ng-options='state.StateCode as state.StateName for state in States'>

much much faster than

<option ng-repeat="state in States" value="{{state.StateCode}}">
    {{state.StateName }}
</option>

You can try to use:

where(date: p[:date]..Float::INFINITY)

equivalent in sql

WHERE (`date` >= p[:date])

The result is:

Note.where(user_id: current_user.id, notetype: p[:note_type], date: p[:date]..Float::INFINITY).order(:fecha, :created_at)

And I have changed too

order('date ASC, created_at ASC')

For

order(:fecha, :created_at)

I propose it remove the non printable characters like below instead of replacing it

private String removeNonBMPCharacters(final String input) {
    StringBuilder strBuilder = new StringBuilder();
    input.codePoints().forEach((i) -> {
        if (Character.isSupplementaryCodePoint(i)) {
            strBuilder.append("?");
        } else {
            strBuilder.append(Character.toChars(i));
        }
    });
    return strBuilder.toString();
}

Does your upload die at the very end? 99% before crashing? Client body and buffers are key because nginx must buffer incoming data. The body configs (data of the request body) specify how nginx handles the bulk flow of binary data from multi-part-form clients into your app's logic.

The clean setting frees up memory and consumption limits by instructing nginx to store incoming buffer in a file and then clean this file later from disk by deleting it.

Set body_in_file_only to clean and adjust buffers for the client_max_body_size. The original question's config already had sendfile on, increase timeouts too. I use the settings below to fix this, appropriate across your local config, server, & http contexts.

client_body_in_file_only clean;
client_body_buffer_size 32K;

client_max_body_size 300M;

sendfile on;
send_timeout 300s;

The make uses the $ for its own variable expansions. E.g. single character variable $A or variable with a long name - ${VAR} and $(VAR).

To put the $ into a command, use the $$, for example:

all:
  @echo "Please execute next commands:"
  @echo 'setenv PATH /usr/local/greenhills/mips5/linux86:$$PATH'

Also note that to make the "" and '' (double and single quoting) do not play any role and they are passed verbatim to the shell. (Remove the @ sign to see what make sends to shell.) To prevent the shell from expanding $PATH, second line uses the ''.

If you are looking to have multiple subscripts in one text then use the star(*) to separate the sections:

plot(1:10, xlab=expression('hi'[5]*'there'[6]^8*'you'[2]))

For me a typical while loop will be something like this:

xBool = True
# A counter to force a condition (eg. yCount = some integer value)

while xBool:
    # set up the condition (eg. if yCount > 0):
        (Do something)
        yCount = yCount - 1
    else:
        # (condition is not met, set xBool False)
        xBool = False

I could include a for..loop within the while loop as well, if situation so warrants, for looping through another set of condition.

In the lastest version of code with express-generator (4.13.1) app.js is an exported module and the server is started in /bin/www using app.set('port', process.env.PORT || 3001) in app.js will be overridden by a similar statement in bin/www. I just changed the statement in bin/www.

It looks like you are running something in Windows by double clicking on it. This will execute the program in a new window and close the window when it terminates. No wonder you cannot read the output.

A better way to do this would be to switch to the command prompt. Navigate (cd) to the directory where the program is located and then call it using python. Something like this:

C:\> cd C:\my_programs\
C:\my_programs\> python area.py

Replace my_programs with the actual location of your program and area.py with the name of your python file.

For those looking where to place the image file on the Jupyter machine so that it could be shown from the local file system.

I put my mypic.png into

/root/Images/mypic.png

(that is the Images folder that shows up in the Jupyter online file browser)

In that case I need to put the following line into the Markdown cell to make my pic showing in the notepad:

![My Title](Images/mypic.png)

DEBUG will show all messages, INFO all besides DEBUG messages, and so on.
Usually one uses either INFO or WARN. This dependens on the company policy.

Depending on your logic, if you want to close only the current fragment you have to pass viewLifecycleOwner, code is shown below:

   requireActivity().onBackPressedDispatcher.addCallback(viewLifecycleOwner, object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            requireActivity().finish()
        }
    })

However, if you want to close application on backPressed no matter from what fragment(probably you wouldn't want that!), don't pass the viewLifecycleOwner. Also if you want to disable the back button, do not do anything inside the handleOnBackPressed(), see below:

 requireActivity().onBackPressedDispatcher.addCallback(viewLifecycleOwner, object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            // do nothing it will disable the back button
        }
    })

I use the following for VB.Net:

<%# If(Eval("item").ToString() Is DBNull.Value, "0 value", Eval("item")) %>

This is my 2 cents based on Grax's answer, but with two parameters required for a generic method.

Assume your method is defined as follows in an Helpers class:

public class Helpers
{
    public static U ConvertCsvDataToCollection<U, T>(string csvData)
    where U : ObservableCollection<T>
    {
      //transform code here
    }
}

In my case, U type is always an observable collection storing object of type T.

As I have my types predefined, I first create the "dummy" objects that represent the observable collection (U) and the object stored in it (T) and that will be used below to get their type when calling the Make

object myCollection = Activator.CreateInstance(collectionType);
object myoObject = Activator.CreateInstance(objectType);

Then call the GetMethod to find your Generic function:

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

So far, the above call is pretty much identical as to what was explained above but with a small difference when you need have to pass multiple parameters to it.

You need to pass an Type[] array to the MakeGenericMethod function that contains the "dummy" objects' types that were create above:

MethodInfo generic = method.MakeGenericMethod(
new Type[] {
   myCollection.GetType(),
   myObject.GetType()
});

Once that's done, you need to call the Invoke method as mentioned above.

generic.Invoke(null, new object[] { csvData });

And you're done. Works a charm!

UPDATE:

As @Bevan highlighted, I do not need to create an array when calling the MakeGenericMethod function as it takes in params and I do not need to create an object in order to get the types as I can just pass the types directly to this function. In my case, since I have the types predefined in another class, I simply changed my code to:

object myCollection = null;

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

MethodInfo generic = method.MakeGenericMethod(
   myClassInfo.CollectionType,
   myClassInfo.ObjectType
);

myCollection = generic.Invoke(null, new object[] { csvData });

myClassInfo contains 2 properties of type Type which I set at run time based on an enum value passed to the constructor and will provide me with the relevant types which I then use in the MakeGenericMethod.

Thanks again for highlighting this @Bevan.

Actually for some reason wireshark uses two different kind of filter syntax one on display filter and other on capture filter. Display filter is only useful to find certain traffic just for display purpose only. its like you are interested in all trafic but for now you just want to see specific.

but if you are interested only in certian traffic and does not care about other at all then you use the capture filter.

The Syntax for display filter is (as mentioned earlier)

ip.addr = x.x.x.x or ip.src = x.x.x.x or ip.dst = x.x.x.x

but above syntax won't work in capture filters, following are the filters

host x.x.x.x

see more example on wireshark wiki page

putPref("myKey", "mystring", getApplicationContext());

call this when you want to get a pref:

getPref("myKey", getApplicationContext());

Or you can use this object https://github.com/kcochibili/TinyDB--Android-Shared-Preferences-Turbo which simplifies everything even further

Example:

TinyDB tinydb = new TinyDB(context);

tinydb.putInt("clickCount", 2);
tinydb.putFloat("xPoint", 3.6f);
tinydb.putLong("userCount", 39832L);

tinydb.putString("userName", "john");
tinydb.putBoolean("isUserMale", true); 

tinydb.putList("MyUsers", mUsersArray);
tinydb.putImagePNG("DropBox/WorkImages", "MeAtlunch.png", lunchBitmap);

Based on what React Docs say:

Handling Multiple Inputs. When you need to handle multiple controlled input elements, you can add a name attribute to each element and let the handler function choose what to do based on the value of event.target.name.

For example:

class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {};
  }

  handleChange = e => {
    const { name, value } = e.target;

    this.setState({
      [name]: value
    });
  };

  render() {
    return (
      <div className="radio-buttons">
        Windows
        <input
          id="windows"
          value="windows"
          name="platform"
          type="radio"
          onChange={this.handleChange}
        />
        Mac
        <input
          id="mac"
          value="mac"
          name="platform"
          type="radio"
          onChange={this.handleChange}
        />
        Linux
        <input
          id="linux"
          value="linux"
          name="platform"
          type="radio"
          onChange={this.handleChange}
        />
      </div>
    );
  }
}

At first, none of the radio buttons is selected so this.state is an empty object, but whenever the radio button is selected this.state gets a new property with the name of the input and its value. It eases then to check whether user selected any radio-button like:

const isSelected = this.state.platform ? true : false;

EDIT:

With version 16.7-alpha of React there is a proposal for something called hooks which will let you do this kind of stuff easier:

In the example below there are two groups of radio-buttons in a functional component. Still, they have controlled inputs:

function App() {
  const [platformValue, plaftormInputProps] = useRadioButtons("platform");
  const [genderValue, genderInputProps] = useRadioButtons("gender");
  return (
    <div>
      <form>
        <fieldset>
          Windows
          <input
            value="windows"
            checked={platformValue === "windows"}
            {...plaftormInputProps}
          />
          Mac
          <input
            value="mac"
            checked={platformValue === "mac"}
            {...plaftormInputProps}
          />
          Linux
          <input
            value="linux"
            checked={platformValue === "linux"}
            {...plaftormInputProps}
          />
        </fieldset>
        <fieldset>
          Male
          <input
            value="male"
            checked={genderValue === "male"}
            {...genderInputProps}
          />
          Female
          <input
            value="female"
            checked={genderValue === "female"}
            {...genderInputProps}
          />
        </fieldset>
      </form>
    </div>
  );
}

function useRadioButtons(name) {
  const [value, setState] = useState(null);

  const handleChange = e => {
    setState(e.target.value);
  };

  const inputProps = {
    name,
    type: "radio",
    onChange: handleChange
  };

  return [value, inputProps];
}

To achieve this you can use a Regular Expression to remove all the whitespace in the string. If the length of the resulting string is 0, then you can be sure the original only contained whitespace. Try this:

var str = "    ";_x000D_
if (!str.replace(/\s/g, '').length) {_x000D_
  console.log('string only contains whitespace (ie. spaces, tabs or line breaks)');_x000D_
}

node-http-proxy is a great solution as was suggested by @hross above. If you're not deadset on using node, we use NGINX to do the same thing. It works really well with node. We use it for example to process SSL requests before forwarding them to node. It can also handle cacheing and forwarding routes. Yay!

I'm not cool enough to be able to comment on a post. so I guess I need to make a new post. However the above recommendation of "sudo nmap -sn 192.168.0.0/24" is the best quickest method to get the all the MACs for the IPs on your local network/vlan/subnet What the OP doesnt mention, is the only way to get the MAC address this way, you MUST use sudo(or other super user privs i.e. windows admin) the command nmap -sn 192.168.0.0/24 will discover hosts on your network, however will not return the MACs as you are not in SU mode of operation.

Dim rows() AS DataRow = DataTable.Select("ColumnName1 = 'value3'")
If rows.Count > 0 Then
     searchedValue = rows(0).Item("ColumnName2") 
End If

With FirstOrDefault:

Dim row AS DataRow = DataTable.Select("ColumnName1 = 'value3'").FirstOrDefault()
If Not row Is Nothing Then
     searchedValue = row.Item("ColumnName2") 
End If

In C#:

var row = DataTable.Select("ColumnName1 = 'value3'").FirstOrDefault();
if (row != null)
     searchedValue = row["ColumnName2"];

Without For loop:

Dim newColumn As New Data.DataColumn("Foo", GetType(System.String))     
newColumn.DefaultValue = "Your DropDownList value" 
table.Columns.Add(newColumn) 

C#:

System.Data.DataColumn newColumn = new System.Data.DataColumn("Foo", typeof(System.String));
newColumn.DefaultValue = "Your DropDownList value";
table.Columns.Add(newColumn);

You are not passing your 2D array correctly. This should work for you

int rotateArr(int *arr[])

or

int rotateArr(int **arr) 

or

int rotateArr(int arr[][N]) 

Rather than returning the array pass the target array as argument. See John Bode's answer.

comdlg32.dll is not really a COM dll (you can't register it).

What you need is comdlg32.ocx which contains the MSComDlg.CommonDialog COM class (and indeed relies on comdlg32.dll to work). Once you get ahold on a comdlg32.ocx, then you will be able to do regsvr32 comdlg32.ocx.

I had a case where it had something to do with the order of the different filetypes. Try to change it and see if that helps.

How wide is the text column?

With a GROUP BY there's not much you can do to avoid a data scan (at least an index scan).

I'd recommend:

1. If possible, changing the schema to remove duplication of text data. This way the count will happen on a narrow foreign key field in the 'many' table.

2. Alternatively, creating a generated column with a HASH of the text, then GROUP BY the hash column. Again, this is to decrease the workload (scan through a narrow column index)

Edit:

Your original question did not quite match your edit. I'm not sure if you're aware that the COUNT, when used with a GROUP BY, will return the count of items per group and not the count of items in the entire table.

A p tag is for a paragraph, generally used for text. A div tag is for division, and generally used for creating sections of text.

function sortMultiFields(prop){
    return function(a,b){
        for(i=0;i<prop.length;i++)
        {
            var reg = /^\d+$/;
            var x=1;
            var field1=prop[i];
            if(prop[i].indexOf("-")==0)
            {
                field1=prop[i].substr(1,prop[i].length);
                x=-x;
            }

            if(reg.test(a[field1]))
            {
                a[field1]=parseFloat(a[field1]);
                b[field1]=parseFloat(b[field1]);
            }
            if( a[field1] > b[field1])
                return x;
            else if(a[field1] < b[field1])
                return -x;
        }
    }
}

How to use (put -(minus) sign before field if you want to sort in descending order particular field)

homes.sort(sortMultiFields(["city","-price"]));

Using above function you can sort any json array with multiple fields. No need to change function body at all

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

As of 27 February 2019, there are CSS fonts for the new Material Icon themes.

However, you have to create CSS classes to use the fonts.

The font families are as follows:

• Material Icons Outlined - Outlined icons
• Material Icons Two Tone - Two-tone icons
• Material Icons Round - Rounded icons
• Material Icons Sharp - Sharp icons

See the code sample below for an example:

This will make image shrink if it's too big for specified area (as downside, it will not enlarge image).

Basically, there are two ways to clear the cache:

<form autocomplete="off"></form>

or

$('#Textfiledid').attr('autocomplete', 'off');

The "no frills" options are as follows:

ActiveSheet.Name = "New Name"

and

Sheets("Sheet2").Name = "New Name"

You can also check out recording macros and seeing what code it gives you, it's a great way to start learning some of the more vanilla functions.

do just

<dependency>
   <groupId>javax.el</groupId>
   <artifactId>javax.el-api</artifactId>
   <version>2.2.4</version>
</dependency>

In many case you will need to add the bodyParser module in your express node app. Then in your app.use part below app.use(express.static('www')); add these 2 lines app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json());

Very often this error appears if you use incompatible versions of Selenium and ChromeDriver.

Selenium 3.0.1 for Maven project:

    <dependency>
        <groupId>org.seleniumhq.selenium</groupId>
        <artifactId>selenium-java</artifactId>
        <version>3.0.1</version>
    </dependency>

ChromeDriver 2.27: https://sites.google.com/a/chromium.org/chromedriver/downloads

Also remember, when running on alternate ports, you need to specify the port on the URL:

http://www.example.com:8080

There may be firewalls or proxy servers to consider depending on your environment.

git rev-parse Also works for getting the current branch name using the --abbrev-ref flag like:

git rev-parse --abbrev-ref HEAD

Create the opposite dictionary:

PIX1 = {}
for key in PIX0.keys():
    PIX1[PIX0.get(key)] = key

Then run the same code on this dictionary instead (using PIX1 instead of PIX0).

BTW, I'm not sure about Python 3, but in Python 2 you need to use raw_input instead of input.

In my case the issue revealed to be chrome blocking the CORS request from localhost:4200 to facebook api website. Running Chrome with this setting: "YOUR_PATH_TO_CHROME\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir="c:/chrome worked like a charm while developing. Even with no localhost added to facebook app's settings.

You can use this code for generating has code for a given string.

int hash = 7;
for (int i = 0; i < strlen; i++) {
    hash = hash*31 + charAt(i);
}

You may use any standard encoding of your specific usage and input.

utf-8 is the default.

iso8859-1 is also popular for Western Europe.

e.g: bytes_obj.decode('iso8859-1')

It's simple with open source 7zip SFX-Packager - easy way to just "Drag & drop" folders onto it, and it creates a portable/self-extracting package.

1. PSYoungGen refers to the garbage collector in use for the minor collection. PS stands for Parallel Scavenge.
2. The first set of numbers are the before/after sizes of the young generation and the second set are for the entire heap. (Diagnosing a Garbage Collection problem details the format)
3. The name indicates the generation and collector in question, the second set are for the entire heap.

An example of an associated full GC also shows the collectors used for the old and permanent generations:

3.757: [Full GC [PSYoungGen: 2672K->0K(35584K)] 
            [ParOldGen: 3225K->5735K(43712K)] 5898K->5735K(79296K) 
            [PSPermGen: 13533K->13516K(27584K)], 0.0860402 secs]

Finally, breaking down one line of your example log output:

8109.128: [GC [PSYoungGen: 109884K->14201K(139904K)] 691015K->595332K(1119040K), 0.0454530 secs]

• 107Mb used before GC, 14Mb used after GC, max young generation size 137Mb
• 675Mb heap used before GC, 581Mb heap used after GC, 1Gb max heap size
• minor GC occurred 8109.128 seconds since the start of the JVM and took 0.04 seconds

All your problems are that you are mixing content type negotiation with parameter passing. They are things at different levels. More specific, for your question 2, you constructed the response header with the media type your want to return. The actual content negotiation is based on the accept media type in your request header, not response header. At the point the execution reaches the implementation of the method getPersonFormat, I am not sure whether the content negotiation has been done or not. Depends on the implementation. If not and you want to make the thing work, you can overwrite the request header accept type with what you want to return.

return new ResponseEntity<>(PersonFactory.createPerson(), httpHeaders, HttpStatus.OK);

I used the http://www.javadecompilers.com but in some classes it gives you the message "could not load this classes..."

INSTEAD download Android Studio, navigate to the folder containing the java class file and double click it. The code will show in the right pane and I guess you can copy it an save it as a java file from there

don't know as of which chrome version this is available, but i found a setting 'Console - Log XMLHttpRequests' (clicking on the icon in the bottom right corner of developer tools in chrome on mac)

I found that this can happen if the referenced project is targeting a higher version of the framework than the project that is trying to use it. You can tell if this is the problem by going to the output window and looking for something similar to this:

The primary reference "my_reference" could not be resolved because it was built against the ".NETFramework,Version=v4.7.2" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.7".

The solution is to change the target framework of one or other of the projects.

Use ViewChild with #localvariable as shown here,

<textarea  #someVar  id="tasknote"
                  name="tasknote"
                  [(ngModel)]="taskNote"
                  placeholder="{{ notePlaceholder }}"
                  style="background-color: pink"
                  (blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }} 

</textarea>

In component,

OLDEST Way

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

ngAfterViewInit()
{
   this.el.nativeElement.focus();
}

OLD Way

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor(private rd: Renderer) {}
ngAfterViewInit() {
    this.rd.invokeElementMethod(this.el.nativeElement,'focus');
}

NEW Way

Please note from Angular v4.0.0-rc.3 (2017-03-10) few things have been changed. Since Angular team will deprecate invokeElementMethod, above code no longer can be used.

BREAKING CHANGES

since 4.0 rc.1:

rename RendererV2 to Renderer2
rename RendererTypeV2 to RendererType2
rename RendererFactoryV2 to RendererFactory2

import {ElementRef,Renderer2} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor(private rd: Renderer2) {}

ngAfterViewInit() {
      console.log(this.rd); 
      this.el.nativeElement.focus();      //<<<=====same as oldest way
}

console.log(this.rd) will give you following methods and you can see now invokeElementMethod is not there. Attaching img as yet it is not documented.

NOTE: You can use following methods of Rendere2 with/without ViewChild variable to do so many things.

I've made a very simple extension method to wait for all threads of a collection:

using System.Collections.Generic;
using System.Threading;

namespace Extensions
{
    public static class ThreadExtension
    {
        public static void WaitAll(this IEnumerable<Thread> threads)
        {
            if(threads!=null)
            {
                foreach(Thread thread in threads)
                { thread.Join(); }
            }
        }
    }
}

Then you simply call:

List<Thread> threads=new List<Thread>();
// Add your threads to this collection
threads.WaitAll();

you do not need to pull 'picture' attribute though. there is much more convenient way, the only thing you need is userid, see example below;

https://graph.facebook.com/user_id/picture?type=large

p.s. type defines the size you want

plz keep in mind that using token with basic permissions, /me/friends will return list of friends only with id+name attributes

Another trick to get the link color working correctly inside the <button> markup

<button type="button" class="btn btn-outline-success and-all-other-classes"> 
  <a href="#" style="color:inherit"> Button text with correct colors </a>
</button>

Please keep in mind that in bs4 beta e.g. btn-primary-outline changed to btn-outline-primary

There has been some major changes in ms 2008 -> Might be worth considering the following article when making a decisions on what data type to use. http://msdn.microsoft.com/en-us/library/ms143432.aspx

Bytes per

1. varchar(max), varbinary(max), xml, text, or image column 2^31-1 2^31-1
2. nvarchar(max) column 2^30-1 2^30-1

Just a note to add on here: it's now 3 years later, yet this post is top in Google when you type in "How to search an S3 Bucket."

Perhaps you're looking for something more complex, but if you landed here trying to figure out how to simply find an object (file) by it's title, it's crazy simple:

open the bucket, select "none" on the right hand side, and start typing in the file name.

http://docs.aws.amazon.com/AmazonS3/latest/UG/ListingObjectsinaBucket.html

For example, I get date/time in format Spanish.

$('#timePicker').datetimepicker({
    defaultDate: new Date(),
    format:'DD/MM/YYYY HH:mm'
});

There are 3 states for boolean in PG: true, false and unknown (null). Explained here: Postgres boolean datatype

Therefore you need only query for NOT TRUE:

SELECT * from table_name WHERE boolean_column IS NOT TRUE;

random.sample(population, k)

It is used for randomly sampling a sample of length 'k' from a population. returns a 'k' length list of unique elements chosen from the population sequence or set

it returns a new list and leaves the original population unchanged and the resulting list is in selection order so that all sub-slices will also be valid random samples

I am putting up an example in which I am splitting a dataset randomly. It is basically a function in which you pass x_train(population) as an argument and return indices of 60% of the data as D_test.

import random

def randomly_select_70_percent_of_data_from_1_to_length(x_train):
    return random.sample(range(0, len(x_train)), int(0.6*len(x_train)))

Here's another decoder that works well as of 2014: http://viewstatedecoder.azurewebsites.net/

This worked on an input on which the Ignatu decoder failed with "The serialized data is invalid" (although it leaves the BinaryFormatter-serialized data undecoded, showing only its length).

Active Directory is a database based system that provides authentication, directory, policy, and other services in a Windows environment

LDAP (Lightweight Directory Access Protocol) is an application protocol for querying and modifying items in directory service providers like Active Directory, which supports a form of LDAP.

Short answer: AD is a directory services database, and LDAP is one of the protocols you can use to talk to it.

Here are my findings after going through many good answers here as well as a few other articles.

First, if you are debating between timeit and time.time, the timeit has two advantages:

1. timeit selects the best timer available on your OS and Python version.
2. timeit disables garbage collection, however, this is not something you may or may not want.

Now the problem is that timeit is not that simple to use because it needs setup and things get ugly when you have a bunch of imports. Ideally, you just want a decorator or use with block and measure time. Unfortunately, there is nothing built-in available for this so you have two options:

Option 1: Use timebudget library

The timebudget is a versatile and very simple library that you can use just in one line of code after pip install.

@timebudget  # Record how long this function takes
def my_method():
    # my code

Option 2: Use my small module

I created below little timing utility module called timing.py. Just drop this file in your project and start using it. The only external dependency is runstats which is again small.

Now you can time any function just by putting a decorator in front of it:

import timing

@timing.MeasureTime
def MyBigFunc():
    #do something time consuming
    for i in range(10000):
        print(i)

timing.print_all_timings()

If you want to time portion of code then just put it inside with block:

import timing

#somewhere in my code

with timing.MeasureBlockTime("MyBlock"):
    #do something time consuming
    for i in range(10000):
        print(i)

# rest of my code

timing.print_all_timings()

Advantages:

There are several half-backed versions floating around so I want to point out few highlights:

1. Use timer from timeit instead of time.time for reasons described earlier.
2. You can disable GC during timing if you want.
3. Decorator accepts functions with named or unnamed params.
4. Ability to disable printing in block timing (use with timing.MeasureBlockTime() as t and then t.elapsed).
5. Ability to keep gc enabled for block timing.

For everyone who looks example that works with Swift 2.2, Abizern code with modern do try catch handle of error

func databaseURL() -> NSURL? {

    let fileManager = NSFileManager.defaultManager()

    let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

    if let documentDirectory:NSURL = urls.first { // No use of as? NSURL because let urls returns array of NSURL
        // This is where the database should be in the documents directory
        let finalDatabaseURL = documentDirectory.URLByAppendingPathComponent("OurFile.plist")

        if finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) {
            // The file already exists, so just return the URL
            return finalDatabaseURL
        } else {
            // Copy the initial file from the application bundle to the documents directory
            if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {

                do {
                    try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
                } catch let error as NSError  {// Handle the error
                    print("Couldn't copy file to final location! Error:\(error.localisedDescription)")
                }

            } else {
                print("Couldn't find initial database in the bundle!")
            }
        }
    } else {
        print("Couldn't get documents directory!")
    }

    return nil
}

Update I've missed that new swift 2.0 have guard(Ruby unless analog), so with guard it is much shorter and more readable

func databaseURL() -> NSURL? {

let fileManager = NSFileManager.defaultManager()
let urls = fileManager.URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)

// If array of path is empty the document folder not found
guard urls.count != 0 else {
    return nil
}

let finalDatabaseURL = urls.first!.URLByAppendingPathComponent("OurFile.plist")
// Check if file reachable, and if reacheble just return path
guard finalDatabaseURL.checkResourceIsReachableAndReturnError(nil) else {
    // Check if file is exists in bundle folder
    if let bundleURL = NSBundle.mainBundle().URLForResource("OurFile", withExtension: "plist") {
        // if exist we will copy it
        do {
            try fileManager.copyItemAtURL(bundleURL, toURL: finalDatabaseURL)
        } catch let error as NSError { // Handle the error
            print("File copy failed! Error:\(error.localizedDescription)")
        }
    } else {
        print("Our file not exist in bundle folder")
        return nil
    }
    return finalDatabaseURL
}
return finalDatabaseURL 
}

As it has been pointed out by X-Zero, this function returns only an estimate. This is true. For accurate results I would use the following to get the difference in days between two dates a and b:

SELECT days (current date) - days (date(TIMESTAMP_FORMAT(CHDLM, 'YYYYMMDD')))

SQLTools is an almost fully functional and free Oracle GUI:

Functionally, they are identical. So to choose which one to use is totally a personal preference. Semantically in English, they are different. Die sounds negative. When I have a function which returns JSON data to the client and terminate the program, it can be awful if I call this function jsonDie(), and it is more appropriate to call it jsonExit(). For that reason, I always use exit instead of die.

In ONLINE mode the new index is built while the old index is accessible to reads and writes. any update on the old index will also get applied to the new index. An antimatter column is used to track possible conflicts between the updates and the rebuild (ie. delete of a row which was not yet copied). See Online Index Operations. When the process is completed the table is locked for a brief period and the new index replaces the old index. If the index contains LOB columns, ONLINE operations are not supported in SQL Server 2005/2008/R2.

In OFFLINE mode the table is locked upfront for any read or write, and then the new index gets built from the old index, while holding a lock on the table. No read or write operation is permitted on the table while the index is being rebuilt. Only when the operation is done is the lock on the table released and reads and writes are allowed again.

Note that in SQL Server 2012 the restriction on LOBs was lifted, see Online Index Operations for indexes containing LOB columns.

You can use get File path from diffrent SDk versions

Use RealPathUtils for it

public class RealPathUtils {

public static String getRealPathFromURI_API19(Context context, Uri uri){
    String filePath = "";
    String wholeID = DocumentsContract.getDocumentId(uri);

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    String[] column = { MediaStore.Images.Media.DATA };

    // where id is equal to
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            column, sel, new String[]{ id }, null);

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();
    return filePath;
}

    Cursor cursor = cursorLoader.loadInBackground();

    if(cursor != null){

**Now get the file Path from URI **

 String path = null;
                if (Build.VERSION.SDK_INT < 11)

How about:

Function GetLastRow(strSheet, strColumn) As Long
    Dim MyRange As Range

    Set MyRange = Worksheets(strSheet).Range(strColumn & "1")
    GetLastRow = Cells(Rows.Count, MyRange.Column).End(xlUp).Row
End Function

Regarding a comment, this will return the row number of the last cell even when only a single cell in the last row has data:

Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row

This is a good JavaScript solution to the validation issue you have:

/\b\d{5}-\d{4}\b/

If Data Is not Loaded From savedInstanceState use following code.
The problem is url call is not to complete fully so, check if data is loaded then to show the instanceState value.

//suppose data is not Loaded to savedInstanceState at 1st swipe
if (savedInstanceState == null && !mAlreadyLoaded){
    mAlreadyLoaded = true;
    GetStoryData();//Url Call
} else {
    if (listArray != null) {  //Data Array From JsonArray(ListArray)
        System.out.println("LocalData  " + listArray);
        view.findViewById(R.id.progressBar).setVisibility(View.GONE);
    }else{
        GetStoryData();//Url Call
    }
}

The alternative way to check if an array is empty could be:

count($array)>0

It works for me without that error

You can use pop():

x=[2,3,4,5,6,7]
print(x.pop(2))

output is 4

alternatively, SQL%ROWCOUNT you can use this within the procedure without any need to declare a variable

Did you check the gsl package in your system. Try with this:

ldconfig-p | grep gsl

If gsl is installed, it will display the configuration path. If it is not in the standard path /usr/lib/ then you need to do the following in bash:

export PATH=$PATH:/your/path/to/gsl-config 

If gsl is not installed, simply do

sudo apt-get install libgsl0ldbl
sudo apt-get install gsl-bin libgsl0-dev

I had a problem with the mvabund package and this fixed the error

Here are few examples from PostgreSQL-9.5

Display list:

1. Functions: \df+
2. Triggers : \dy+

One way to do this with MS Access is with a subquery but it does not have anything like the same functionality:

SELECT a.ID, 
       a.AText, 
       (SELECT Count(ID) 
        FROM table1 b WHERE b.ID <= a.ID 
        AND b.AText Like "*a*") AS RowNo
FROM Table1 AS a
WHERE a.AText Like "*a*"
ORDER BY a.ID;

install exceljs and use the following code,

var Excel = require('exceljs');

var wb = new Excel.Workbook();
var path = require('path');
var filePath = path.resolve(__dirname,'sample.xlsx');

wb.xlsx.readFile(filePath).then(function(){

    var sh = wb.getWorksheet("Sheet1");

    sh.getRow(1).getCell(2).value = 32;
    wb.xlsx.writeFile("sample2.xlsx");
    console.log("Row-3 | Cell-2 - "+sh.getRow(3).getCell(2).value);

    console.log(sh.rowCount);
    //Get all the rows data [1st and 2nd column]
    for (i = 1; i <= sh.rowCount; i++) {
        console.log(sh.getRow(i).getCell(1).value);
        console.log(sh.getRow(i).getCell(2).value);
    }
});

The simplest and most reliable solution is inserting flex items at the right places. If they are wide enough (width: 100%), they will force a line break.

.container {_x000D_
  background: tomato;_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
  align-content: space-between;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
.item {_x000D_
  width: 100px;_x000D_
  background: gold;_x000D_
  height: 100px;_x000D_
  border: 1px solid black;_x000D_
  font-size: 30px;_x000D_
  line-height: 100px;_x000D_
  text-align: center;_x000D_
  margin: 10px_x000D_
}_x000D_
.item:nth-child(4n - 1) {_x000D_
  background: silver;_x000D_
}_x000D_
.line-break {_x000D_
  width: 100%;_x000D_
}

<div class="container">_x000D_
  <div class="item">1</div>_x000D_
  <div class="item">2</div>_x000D_
  <div class="item">3</div>_x000D_
  <div class="line-break"></div>_x000D_
  <div class="item">4</div>_x000D_
  <div class="item">5</div>_x000D_
  <div class="item">6</div>_x000D_
  <div class="line-break"></div>_x000D_
  <div class="item">7</div>_x000D_
  <div class="item">8</div>_x000D_
  <div class="item">9</div>_x000D_
  <div class="line-break"></div>_x000D_
  <div class="item">10</div>_x000D_
</div>

But that's ugly and not semantic. Instead, we could generate pseudo-elements inside the flex container, and use order to move them to the right places.

.container {_x000D_
  background: tomato;_x000D_
  display: flex;_x000D_

  line-height: 100px;_x000D_
  text-align: center;_x000D_
  margin: 10px_x000D_
}_x000D_
.item:nth-child(3n) {_x000D_
  background: silver;_x000D_
}_x000D_
.container::before, .container::after {_x000D_
  content: '';_x000D_

.item:nth-child(n + 4) {_x000D_
  order: 1;_x000D_

.item:nth-child(n + 7) {_x000D_
  order: 2;_x000D_
}

But there is a limitation: the flex container can only have a ::before and a ::after pseudo-element. That means you can only force 2 line breaks.

To solve that, you can generate the pseudo-elements inside the flex items instead of in the flex container. This way you won't be limited to 2. But those pseudo-elements won't be flex items, so they won't be able to force line breaks.

But luckily, CSS Display L3 has introduced display: contents (currently only supported by Firefox 37):

The element itself does not generate any boxes, but its children and pseudo-elements still generate boxes as normal. For the purposes of box generation and layout, the element must be treated as if it had been replaced with its children and pseudo-elements in the document tree.

So you can apply display: contents to the children of the flex container, and wrap the contents of each one inside an additional wrapper. Then, the flex items will be those additional wrappers and the pseudo-elements of the children.

.container {_x000D_
  background: tomato;_x000D_

.item:nth-child(3n)::after {_x000D_
  content: '';_x000D_
  width: 100%;_x000D_
}

<div class="container">_x000D_

Alternatively, according to Fragmenting Flex Layout and CSS Fragmentation, Flexbox allows forced breaks by using break-before, break-after or their CSS 2.1 aliases:

.item:nth-child(3n) {
  page-break-after: always; /* CSS 2.1 syntax */
  break-after: always; /* New syntax */
}

.container {_x000D_
  background: tomato;_x000D_
  display: flex;_x000D_
  flex-flow: row wrap;_x000D_
  align-content: space-between;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
.item {_x000D_
  width: 100px;_x000D_
  background: gold;_x000D_
  height: 100px;_x000D_
  border: 1px solid black;_x000D_
  font-size: 30px;_x000D_
  line-height: 100px;_x000D_
  text-align: center;_x000D_
  margin: 10px_x000D_
}_x000D_
.item:nth-child(3n) {_x000D_
  page-break-after: always;_x000D_
  background: silver;_x000D_
}

<div class="container">_x000D_
  <div class="item">1</div>_x000D_
  <div class="item">2</div>_x000D_
  <div class="item">3</div>_x000D_
  <div class="item">4</div>_x000D_
  <div class="item">5</div>_x000D_
  <div class="item">6</div>_x000D_

  <div class="item">8</div>_x000D_
  <div class="item">9</div>_x000D_
  <div class="item">10</div>_x000D_
</div>

Forced line breaks in flexbox are not widely supported yet, but it works on Firefox.

Try to see if the following code helps you:

Dim iDate As String = "05/05/2005"
Dim oDate As DateTime = Convert.ToDateTime(iDate)

Using modernizr

Modernizr.addTest('ie', function () {
    var ua = window.navigator.userAgent;
    var msie = ua.indexOf('MSIE ') > 0;
    var ie11 = ua.indexOf('Trident/') > 0;
    var ie12 = ua.indexOf('Edge/') > 0;
    return msie || ie11 || ie12;

use .filter(':has(:checkbox:checked)' ie:

This is my solution that adjusts the height automatically:

I used the workaround that r3bel posted: Can you use CSS3 to transition from height:0 to the variable height of content?

I deleted everything connected to mysql with

sudo apt-get remove --purge --auto-remove mysql-client-5.7 mysql-client-core-5.7 mysql-common mysql-server-5.7

sudo rm -r /etc/mysql* /var/lib/mysql* /var/log/mysql*

and then reinstalled it again with

sudo apt-get update

sudo apt-get install mysql-server

and then started it with

mysql -u root -p

followed by the password

The above solution is good if all the data is of same dtype. Numpy arrays are homogeneous containers. When you do df.values the output is an numpy array. So if the data has int and float in it then output will either have int or float and the columns will loose their original dtype. Consider df

a  b 
0  1  4
1  2  5 
2  3  6 

a    float64
b    int64 

So if you want to keep original dtype, you can do something like

row_list = df.to_csv(None, header=False, index=False).split('\n')

this will return each row as a string.

['1.0,4', '2.0,5', '3.0,6', '']

Then split each row to get list of list. Each element after splitting is a unicode. We need to convert it required datatype.

def f(row_str): 
  row_list = row_str.split(',')
  return [float(row_list[0]), int(row_list[1])]

df_list_of_list = map(f, row_list[:-1])

[[1.0, 4], [2.0, 5], [3.0, 6]]

You can also cross reference repos:

githubuser/repository#xxx

xxx being the issue number

the core functions are getBytes(String charset) and new String(byte[] data). you can use these functions to do UTF-8 decoding.

UTF-8 decoding actually is a string to string conversion, the intermediate buffer is a byte array. since the target is an UTF-8 string, so the only parameter for new String() is the byte array, which calling is equal to new String(bytes, "UTF-8")

Then the key is the parameter for input encoded string to get internal byte array, which you should know beforehand. If you don't, guess the most possible one, "ISO-8859-1" is a good guess for English user.

The decoding sentence should be

String decoded = new String(encoded.getBytes("ISO-8859-1"));

In your click function, you can write:

function addMoreRows(frm) {
   rowCount ++;
   var recRow = '<p id="rowCount'+rowCount+'"><tr><td><input name="" type="text" size="17%"  maxlength="120" /></td><td><input name="" type="text"  maxlength="120" style="margin: 4px 5px 0 5px;"/></td><td><input name="" type="text" maxlength="120" style="margin: 4px 10px 0 0px;"/></td></tr> <a href="javascript:void(0);" onclick="removeRow('+rowCount+');">Delete</a></p>';
   jQuery('#addedRows').append(recRow);
}

Or follow this link: http://www.discussdesk.com/add-remove-more-rows-dynamically-using-jquery.htm

Use like this.

List<String> stockList = new ArrayList<String>();
stockList.add("stock1");
stockList.add("stock2");

String[] stockArr = new String[stockList.size()];
stockArr = stockList.toArray(stockArr);

for(String s : stockArr)
    System.out.println(s);

Remove the semicolon after hello

Another (silly) possibility is to git commit --amend <<< :wq if you've got vi(m) as $EDITOR.

This example might help someone:

Note "origin" is my alias for remote "What is on Github"
Note "mybranch" is my alias for my branch "what is local" that I'm syncing with github
--your branch name is 'master' if you didn't create one. However, I'm using the different name mybranch to show where the branch name parameter is used.

What exactly are my remote repos on github?

$ git remote -v
origin  https://github.com/flipmcf/Playground.git (fetch)
origin  https://github.com/flipmcf/Playground.git (push)

Add the "other github repository of the same code" - we call this a fork:

$ git remote add someOtherRepo https://github.com/otherUser/Playground.git

$git remote -v
origin  https://github.com/flipmcf/Playground.git (fetch)
origin  https://github.com/flipmcf/Playground.git (push)
someOtherRepo https://github.com/otherUser/Playground.git (push)
someOtherRepo https://github.com/otherUser/Playground.git (fetch)

make sure our local repo is up to date:

$ git fetch

Change some stuff locally. let's say file ./foo/bar.py

$ git status
# On branch mybranch
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)

Commit locally.

$ git commit foo/bar.py -m"I changed stuff"

Now, I'm different than my remote (on github)

$ git status

If above solutions are not working for your TextView then this will definitely work:

1. add this style

<style name="ClickableView">
    <item name="colorControlHighlight">@android:color/white</item>
    <item name="android:background">?selectableItemBackground</item>
</style>

2. use it just by

android:theme="@style/ClickableView"

Put this in your CMakeLists.txt file (change any options from OFF to ON if you want):

set(Boost_USE_STATIC_LIBS OFF) 
set(Boost_USE_MULTITHREADED ON)  
set(Boost_USE_STATIC_RUNTIME OFF) 
find_package(Boost 1.45.0 COMPONENTS *boost libraries here*) 

if(Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS}) 
    add_executable(progname file1.cxx file2.cxx) 
    target_link_libraries(progname ${Boost_LIBRARIES})
endif()

Obviously you need to put the libraries you want where I put *boost libraries here*. For example, if you're using the filesystem and regex library you'd write:

find_package(Boost 1.45.0 COMPONENTS filesystem regex)

Thanks, everybody, for replies. I tried to use Directory.GetFiles() and Directory.GetDirectories() methods. Good news! The performance improved ~twice! 229 calls in 221ms. But also I hope, that it is possible to avoid enumeration of all items in the folder. Agree, that still the unnecessary job is executing. Don't you think so?

After all investigations, I reached a conclusion, that under pure .NET further optimiation is impossible. I am going to play with WinAPI's FindFirstFile function. Hope it will help.

It's possible to pass multiple parameters as a single model as vijay suggested. This works for GET when you use the FromUri parameter attribute. This tells WebAPI to fill the model from the query parameters.

The result is a cleaner controller action with just a single parameter. For more information see: http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

public class BooksController : ApiController
  {
    // GET /api/books?author=tolk&title=lord&isbn=91&somethingelse=ABC&date=1970-01-01
    public string GetFindBooks([FromUri]BookQuery query)
    {
      // ...
    }
  }

  public class BookQuery
  {
    public string Author { get; set; }
    public string Title { get; set; }
    public string ISBN { get; set; }
    public string SomethingElse { get; set; }
    public DateTime? Date { get; set; }
  }

It even supports multiple parameters, as long as the properties don't conflict.

// GET /api/books?author=tolk&title=lord&isbn=91&somethingelse=ABC&date=1970-01-01
public string GetFindBooks([FromUri]BookQuery query, [FromUri]Paging paging)
{
  // ...
}

public class Paging
{
  public string Sort { get; set; }
  public int Skip { get; set; }
  public int Take { get; set; }
}

Update:
In order to ensure the values are optional make sure to use reference types or nullables (ex. int?) for the models properties.

Try this...

1. For Showing keyboard

   editText.requestFocus();
   InputMethodManager imm = (InputMethodManager) ctx.getSystemService(Context.INPUT_METHOD_SERVICE);
   imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
   

2. For Hide keyboard

   InputMethodManager inputManager = (InputMethodManager) ctx.getSystemService(Context.INPUT_METHOD_SERVICE); 
   inputManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
   

Note that I don't recommend a fixed IP for containers in Docker unless you're doing something that allows routing from outside to the inside of your container network (e.g. macvlan). DNS is already there for service discovery inside of the container network and supports container scaling. And outside the container network, you should use exposed ports on the host. With that disclaimer, here's the compose file you want:

version: '2'

services:
  mysql:
    container_name: mysql
    image: mysql:latest
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=root
    ports:
     - "3306:3306"
    networks:
      vpcbr:
        ipv4_address: 10.5.0.5

  apigw-tomcat:

     - "8009:8009"
    networks:

        ipv4_address: 10.5.0.6
    depends_on:

There's MonoDevelop, which I occasionally use when I want to do some light C# coding when in Linux. It's nothing close to VS.Net, but it works for small projects. I really don't think most of the alternatives people have listed come anywhere close to VS.Net.

The safest way is to rely on the browser TextNode to correctly escape content. Here's an example:

function stripHTML(dirtyString) {_x000D_
  var container = document.createElement('div');_x000D_
  var text = document.createTextNode(dirtyString);_x000D_
  container.appendChild(text);_x000D_
  return container.innerHTML; // innerHTML will be a xss safe string_x000D_
}_x000D_
_x000D_
document.write( stripHTML('<p>some <span>content</span></p>') );_x000D_
document.write( stripHTML('<script><p>some <span>content</span></p>') );

The thing to remember here is that the browser escape the special characters of TextNodes when we access the html strings (innerHTML, outerHTML). By comparison, accessing text values (innerText, textContent) will yield raw strings, meaning they're unsafe and could contains XSS.

If you use jQuery, then using .text() is safe and backward compatible. See the other answers to this question.

The simplest way in pure JavaScript if you work with browsers <= Internet Explorer 8 is:

string.replace(/(<([^>]+)>)/ig,"");

But there's some issue with parsing HTML with regex so this won't provide very good security. Also, this only takes care of HTML characters, so it is not totally xss-safe.

Several reasons:

1. String.Format() is very powerful. You can use simple format indicators (like fixed width, currency, character lengths, etc) right in the format string. You can even create your own format providers for things like expanding enums, mapping specific inputs to much more complicated outputs, or localization.
2. You can do some powerful things by putting format strings in configuration files.
3. String.Format() is often faster, as it uses a StringBuilder and an efficient state machine behind the scenes, whereas string concatenation in .Net is relatively slow. For small strings the difference is negligible, but it can be noticable as the size of the string and number of substituted values increases.
4. String.Format() is actually more familiar to many programmers, especially those coming from backgrounds that use variants of the old C printf() function.

Finally, don't forget StringBuilder.AppendFormat(). String.Format() actually uses this method behind the scenes*, and going to the StringBuilder directly can give you a kind of hybrid approach: explicitly use .Append() (analogous to concatenation) for some parts of a large string, and use .AppendFormat() in others.

_{* [edit] Original answer is now 8 years old, and I've since seen an indication this may have changed when string interpolation was added to .Net. However, I haven't gone back to the reference source to verify the change yet.}

I wanted to keep the formulas in place, which the above code did not do.

Here's what I've been doing, note that this leaves one empty row in the table.

Sub DeleteTableRows(ByRef Table As ListObject, KeepFormulas as boolean)

On Error Resume Next

if not KeepFormulas then
    Table.DataBodyRange.clearcontents
end if

Table.DataBodyRange.Rows.Delete

On Error GoTo 0

End Sub

(PS don't ask me why!)

Rather than setting a flag, it could be more elegant to use JavaScript's Array.prototype.find to find the matching item in the array. The loop will end as soon as a truthy value is returned from the callback, and the array value during that iteration will be the .find call's return value:

function findXX(word) {
    return someArray.find((item, i) => {
        $('body').append('-> '+i+'<br />');
        return item === word;
    }); 
}

const someArray = new Array();
someArray[0] = 't5';
someArray[1] = 'z12';
someArray[2] = 'b88';
someArray[3] = 's55';
someArray[4] = 'e51';
someArray[5] = 'o322';
someArray[6] = 'i22';
someArray[7] = 'k954';

var test = findXX('o322');
console.log('found word:', test);

function findXX(word) {
  return someArray.find((item, i) => {
    $('body').append('-> ' + i + '<br />');
    return item === word;
  });
}

All of the full-featured Java IDE's are good and share all of the same concepts and main features. If you can find your way around one you can probably do the same for any other without much trouble.

EDIT: Google gave us a wonderful gift with the new and free AndroidStudio is very good. I highly recommend it over Eclipse.

It may means that you forgot include a header file that define this struct/union. For example:

foo.h file:

typedef union
{
    struct
    {
        uint8_t FIFO_BYTES_AVAILABLE    : 4;
        uint8_t STATE                   : 3;
        uint8_t CHIP_RDY                : 1;
    };
    uint8_t status;
} RF_CHIP_STATUS_t;

RF_CHIP_STATUS_t getStatus();

main.c file:

.
.
.
if (getStatus().CHIP_RDY) /* This will generate the error, you must add the  #include "foo.h" */
.
.
.

The best approach would be to map a unique ID to each enum type, thus avoiding the pitfalls of ORDINAL and STRING. See this post which outlines 5 ways you can map an enum.

Taken from the link above:

1&2. Using @Enumerated

There are currently 2 ways you can map enums within your JPA entities using the @Enumerated annotation. Unfortunately both EnumType.STRING and EnumType.ORDINAL have their limitations.

If you use EnumType.String then renaming one of your enum types will cause your enum value to be out of sync with the values saved in the database. If you use EnumType.ORDINAL then deleting or reordering the types within your enum will cause the values saved in the database to map to the wrong enums types.

Both of these options are fragile. If the enum is modified without performing a database migration, you could jeopodise the integrity of your data.

3. Lifecycle Callbacks

A possible solution would to use the JPA lifecycle call back annotations, @PrePersist and @PostLoad. This feels quite ugly as you will now have two variables in your entity. One mapping the value stored in the database, and the other, the actual enum.

4. Mapping unique ID to each enum type

The preferred solution is to map your enum to a fixed value, or ID, defined within the enum. Mapping to predefined, fixed value makes your code more robust. Any modification to the order of the enums types, or the refactoring of the names, will not cause any adverse effects.

5. Using Java EE7 @Convert

If you are using JPA 2.1 you have the option to use the new @Convert annotation. This requires the creation of a converter class, annotated with @Converter, inside which you would define what values are saved into the database for each enum type. Within your entity you would then annotate your enum with @Convert.

My preference: (Number 4)

The reason why I prefer to define my ID's within the enum as oppose to using a converter, is good encapsulation. Only the enum type should know of its ID, and only the entity should know about how it maps the enum to the database.

See the original post for the code example.

You can get attribute using javascript,

element.getAttribute(attributeName);

Ex:

var wrap = document.getElementById("wrap");
var myattr = wrap.getAttribute("title");

This is the correct way to change btn color.

 .btn-primary:not(:disabled):not(.disabled).active, 
    .btn-primary:not(:disabled):not(.disabled):active, 
    .show>.btn-primary.dropdown-toggle{
        color: #fff;
        background-color: #F7B432;
        border-color: #F7B432;
    }
