Python Extension. From the Python Docs:

The solution chosen by the Perl developers was to use (?...) as the extension syntax. ? immediately after a parenthesis was a syntax error because the ? would have nothing to repeat, so this didn’t introduce any compatibility problems. The characters immediately after the ? indicate what extension is being used, so (?=foo) is one thing (a positive lookahead assertion) and (?:foo) is something else (a non-capturing group containing the subexpression foo).

Python supports several of Perl’s extensions and adds an extension syntax to Perl’s extension syntax.If the first character after the question mark is a P, you know that it’s an extension that’s specific to Python

https://docs.python.org/3/howto/regex.html

You could use Matcher#start(group) and Matcher#end(group) to build a generic replacement method:

public static String replaceGroup(String regex, String source, int groupToReplace, String replacement) {
    return replaceGroup(regex, source, groupToReplace, 1, replacement);
}

public static String replaceGroup(String regex, String source, int groupToReplace, int groupOccurrence, String replacement) {
    Matcher m = Pattern.compile(regex).matcher(source);
    for (int i = 0; i < groupOccurrence; i++)
        if (!m.find()) return source; // pattern not met, may also throw an exception here
    return new StringBuilder(source).replace(m.start(groupToReplace), m.end(groupToReplace), replacement).toString();
}

public static void main(String[] args) {
    // replace with "%" what was matched by group 1 
    // input: aaa123ccc
    // output: %123ccc
    System.out.println(replaceGroup("([a-z]+)([0-9]+)([a-z]+)", "aaa123ccc", 1, "%"));

    // replace with "!!!" what was matched the 4th time by the group 2
    // input: a1b2c3d4e5
    // output: a1b2c3d!!!e5
    System.out.println(replaceGroup("([a-z])(\\d)", "a1b2c3d4e5", 2, 4, "!!!"));
}

Check online demo here.

With one group in the pattern, you can only get one exact result in that group. If your capture group gets repeated by the pattern (you used the + quantifier on the surrounding non-capturing group), only the last value that matches it gets stored.

You have to use your language's regex implementation functions to find all matches of a pattern, then you would have to remove the anchors and the quantifier of the non-capturing group (and you could omit the non-capturing group itself as well).

Alternatively, expand your regex and let the pattern contain one capturing group per group you want to get in the result:

^([A-Z]+),([A-Z]+),([A-Z]+)$

I cannot comment on the top answers to say this: I would like to add an explicit point which is only implied in the top answers:

The non-capturing group (?...) does not remove any characters from the original full match, it only reorganises the regex visually to the programmer.

To access a specific part of the regex without defined extraneous characters you would always need to use .group(<index>)

Here's a one line solution without a while loop.

The order is preserved in the resulting list.

The potential downsides are

1. It clones the regex for every match.
2. The result is in a different form than expected solutions. You'll need to process them one more time.

let re = /\s*([^[:]+):\"([^"]+)"/g
let str = '[description:"aoeu" uuid:"123sth"]'

(str.match(re) || []).map(e => RegExp(re.source, re.flags).exec(e))

[ [ 'description:"aoeu"',
    'description',
    'aoeu',
    index: 0,
    input: 'description:"aoeu"',
    groups: undefined ],
  [ ' uuid:"123sth"',
    'uuid',
    '123sth',
    index: 0,
    input: ' uuid:"123sth"',
    groups: undefined ] ]

Most of the answers here didn't work for all the postcodes I have in my database. I finally found one that validates with all, using the new regex provided by the government:

https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/413338/Bulk_Data_Transfer_-_additional_validation_valid_from_March_2015.pdf

It isn't in any of the previous answers so I post it here in case they take the link down:

^([Gg][Ii][Rr] 0[Aa]{2})|((([A-Za-z][0-9]{1,2})|(([A-Za-z][A-Ha-hJ-Yj-y][0-9]{1,2})|(([A-Za-z][0-9][A-Za-z])|([A-Za-z][A-Ha-hJ-Yj-y][0-9]?[A-Za-z])))) [0-9][A-Za-z]{2})$

UPDATE: Updated regex as pointed by Jamie Bull. Not sure if it was my error copying or it was an error in the government's regex, the link is down now...

UPDATE: As ctwheels found, this regex works with the javascript regex flavor. See his comment for one that works with the pcre (php) flavor.

Open the console and then enter:

• keys(window) to see variables
• dir(window) to see objects

I did found a way to convert (even bad) html into well formed XML. I started to base this on the DOM loadHTML function. However during time several issues occurred and I optimized and added patches to correct side effects.

  function tryToXml($dom,$content) {
    if(!$content) return false;

    // xml well formed content can be loaded as xml node tree
    $fragment = $dom->createDocumentFragment();
    // wonderfull appendXML to add an XML string directly into the node tree!

    // aappendxml will fail on a xml declaration so manually skip this when occurred
    if( substr( $content,0, 5) == '<?xml' ) {
      $content = substr($content,strpos($content,'>')+1);
      if( strpos($content,'<') ) {
        $content = substr($content,strpos($content,'<'));
      }
    }

    // if appendXML is not working then use below htmlToXml() for nasty html correction
    if(!@$fragment->appendXML( $content )) {
      return $this->htmlToXml($dom,$content);
    }

    return $fragment;
  }



  // convert content into xml
  // dom is only needed to prepare the xml which will be returned
  function htmlToXml($dom, $content, $needEncoding=false, $bodyOnly=true) {

    // no xml when html is empty
    if(!$content) return false;

    // real content and possibly it needs encoding
    if( $needEncoding ) {
      // no need to convert character encoding as loadHTML will respect the content-type (only)
      $content =  '<meta http-equiv="Content-Type" content="text/html;charset='.$this->encoding.'">' . $content;
    }

    // return a dom from the content
    $domInject = new DOMDocument("1.0", "UTF-8");
    $domInject->preserveWhiteSpace = false;
    $domInject->formatOutput = true;

    // html type
    try {
      @$domInject->loadHTML( $content );
    } catch(Exception $e){
      // do nothing and continue as it's normal that warnings will occur on nasty HTML content
    }
        // to check encoding: echo $dom->encoding
        $this->reworkDom( $domInject );

    if( $bodyOnly ) {
      $fragment = $dom->createDocumentFragment();

      // retrieve nodes within /html/body
      foreach( $domInject->documentElement->childNodes as $elementLevel1 ) {
       if( $elementLevel1->nodeName == 'body' and $elementLevel1->nodeType == XML_ELEMENT_NODE ) {
         foreach( $elementLevel1->childNodes as $elementInject ) {
           $fragment->insertBefore( $dom->importNode($elementInject, true) );
         }
        }
      }
    } else {
      $fragment = $dom->importNode($domInject->documentElement, true);
    }

    return $fragment;
  }



    protected function reworkDom( $node, $level = 0 ) {

        // start with the first child node to iterate
        $nodeChild = $node->firstChild;

        while ( $nodeChild )  {
            $nodeNextChild = $nodeChild->nextSibling;

            switch ( $nodeChild->nodeType ) {
                case XML_ELEMENT_NODE:
                    // iterate through children element nodes
                    $this->reworkDom( $nodeChild, $level + 1);
                    break;
                case XML_TEXT_NODE:
                case XML_CDATA_SECTION_NODE:
                    // do nothing with text, cdata
                    break;
                case XML_COMMENT_NODE:
                    // ensure comments to remove - sign also follows the w3c guideline
                    $nodeChild->nodeValue = str_replace("-","_",$nodeChild->nodeValue);
                    break;
                case XML_DOCUMENT_TYPE_NODE:  // 10: needs to be removed
                case XML_PI_NODE: // 7: remove PI
                    $node->removeChild( $nodeChild );
                    $nodeChild = null; // make null to test later
                    break;
                case XML_DOCUMENT_NODE:
                    // should not appear as it's always the root, just to be complete
                    // however generate exception!
                case XML_HTML_DOCUMENT_NODE:
                    // should not appear as it's always the root, just to be complete
                    // however generate exception!
                default:
                    throw new exception("Engine: reworkDom type not declared [".$nodeChild->nodeType. "]");
            }
            $nodeChild = $nodeNextChild;
        } ;
    }

Now this also allows to add more html pieces into one XML which I needed to use myself. In general it can be used like this:

        $c='<p>test<font>two</p>';
    $dom=new DOMDocument('1.0', 'UTF-8');

$n=$dom->appendChild($dom->createElement('info')); // make a root element

if( $valueXml=tryToXml($dom,$c) ) {
  $n->appendChild($valueXml);
}
    echo '<pre/>'. htmlentities($dom->saveXml($n)). '</pre>';

In this example '<p>test<font>two</p>' will nicely be outputed in well formed XML as '<info><p>test<font>two</font></p></info>'. The info root tag is added as it will also allow to convert '<p>one</p><p>two</p>' which is not XML as it has not one root element. However if you html does for sure have one root element then the extra root <info> tag can be skipped.

With this I'm getting real nice XML out of unstructured and even corrupted HTML!

I hope it's a bit clear and might contribute to other people to use it.

You haven't said what language you're using. If it's Perl then it's trivial:

use CGI::Info;

my $info = CGI::Info->new();

if($info->is_mobile()) {
   # Add mobile stuff
}

unless($info->is_mobile()) {
   # Don't do some things on a mobile
}

You should be able to do this by checking the value of $_SERVER['HTTPS'] (it should only be set when using https).

See http://php.net/manual/en/reserved.variables.server.php.

I have tried many include sudo apt-get purge ruby , sudo apt-get remove ruby and sudo aptitude purpe ruby, both with and without '*' at the end. But none of them worked, it's may be I've installed more than one version ruby.

Finally, when I triedsudo apt-get purge ruby1.9(with the version), then it works.

Use double quote to enclose the quote or escape it.

newTemp = mystring.replace(/"/g, "'");

or

newTemp = mystring.replace(/"/g, '\'');

XML-XIG: XML Instance Generator

http://xml-xig.sourceforge.net/

This opensource would be helpful.

Simple use this great free online tool:

https://pratie.tomodea.dev/lab/icalendar/default.asp

Call make command this way:

make CFLAGS=-Dvar=42

And be sure to use $(CFLAGS) in your compile command in the Makefile. As @jørgensen mentioned , putting the variable assignment after the make command will override the CFLAGS value already defined the Makefile.

Alternatively you could set -Dvar=42 in another variable than CFLAGS and then reuse this variable in CFLAGS to avoid completely overriding CFLAGS.

I found out it was:

$ git fetch upstream
$ git merge upstream/master

Almost 5 years later, I think my answer can reduce a little bit the hard work of many people.

Update an element in the DOM with the HTML from the one from the ajax call can be achieved that way

$('#submitform').click(function() {
     $.ajax({
     url: "getinfo.asp",
     data: {
         txtsearch: $('#appendedInputButton').val()
     },
     type: "GET",
     dataType : "html",
     success: function (data){
         $('#showresults').html($('#showresults',data).html());
         // similar to $(data).find('#showresults')
     },
});

or with replaceWith()

// codes

success: function (data){
   $('#showresults').replaceWith($('#showresults',data));
},

Because textContent is not supported in IE8 and older, here is a workaround:

var node = document.getElementById('test'),
var text  = node.textContent || node.innerText;
alert(text);

innerText does work in IE.

const is not immutable.

From the MDN:

The const declaration creates a read-only reference to a value. It does not mean the value it holds is immutable, just that the variable identifier cannot be reassigned.

It depends on what you are after in the Dictionary

Models.TestModels obj = new Models.TestModels();

foreach (var keyValuPair in obj.sp)
{
    // KeyValuePair<int, dynamic>
}

foreach (var key in obj.sp.Keys)
{
     // Int 
}

foreach (var value in obj.sp.Values)
{
    // dynamic
}

You are placing your result in the RETURN value instead of in the passed @rvalue.

From MSDN

(RETURN) Is the integer value that is returned. Stored procedures can return an integer value to a calling procedure or an application.

Changing your procedure.

ALTER procedure S_Comp(@str1 varchar(20),@r varchar(100) out) as 

    declare @str2 varchar(100) 
    set @str2 ='welcome to sql server. Sql server is a product of Microsoft' 
    if(PATINDEX('%'+@str1 +'%',@str2)>0) 
        SELECT @r =  @str1+' present in the string' 
    else 
        SELECT @r = @str1+' not present'

Calling the procedure

  DECLARE @r VARCHAR(100)
  EXEC S_Comp 'Test', @r OUTPUT
  SELECT @r

I had the same problem with Xcode. I followed steps you gave and it didn't work. I became crazy because in every forum I saw, all clues for this problem are the one you gave. I finally saw I put a space after the malloc_error_break, I suppressed it and now it works. A dumb problem but if the solution doesn't work, be sure you haven't put any space before and after the malloc_error_break.

Hope this message will help..

You will use the following query:

SELECT * FROM [table] GROUP BY NUMBER;

Where [table] is the name of the table.

This provides a unique listing for the NUMBER column however the other columns may be meaningless depending on the vendor implementation; which is to say they may not together correspond to a specific row or rows.

Alex' comment looks good but I was still confused with using range. The following worked for me while working on a for condition using length within range.

{% for i in range(0,(nums['list_users_response']['list_users_result']['users'])| length) %}
<li>    {{ nums['list_users_response']['list_users_result']['users'][i]['user_name'] }} </li>
{% endfor %}

This may not be a solution to the question, but to illustrate examples:

import pandas as pd

df = pd.DataFrame({
    'A': [1,1,3,4],
    'B': [2,2,5,6],
    'C': [3,4,7,6],
})

print(df)
df.duplicated(keep=False)
df.duplicated(['A','B'], keep=False)

The outputs:

   A  B  C
0  1  2  3
1  1  2  4
2  3  5  7
3  4  6  6

0    False
1    False
2    False
3    False
dtype: bool

0     True
1     True
2    False
3    False
dtype: bool

You can't select a range without having first selected the sheet it is in. Try to select the sheet first and see if you still get the problem:

sourceSheetSum.Select
sourceSheetSum.Range("C3").Select

You can use the ScriptEngine class and evaluate it as a Javascript string.

ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("js");
Object result = engine.eval("4*5");

There may be a better way, but this one works.

It's simple!!

I resolved this problem by following this steps:

1. Open project properties
2. Click on Signing Tab
3. And uncheck "Sign the assembly"

That's it!!

You could use unions to create structs like the following, which contains a field that tells us which component of the union is actually used:

struct VAROBJECT
{
    enum o_t { Int, Double, String } objectType;

    union
    {
        int intValue;
        double dblValue;
        char *strValue;
    } value;
} object;

This is what worked for me...

$('#dialog').live("dialogclose", function(){
   //code to run on dialog close
});

Try this

textarea::-webkit-input-placeholder {  color: #999;}

Just use window.open() function? The third parameter lets you specify window size.

Example

var strWindowFeatures = "location=yes,height=570,width=520,scrollbars=yes,status=yes";
var URL = "https://www.linkedin.com/cws/share?mini=true&url=" + location.href;
var win = window.open(URL, "_blank", strWindowFeatures);

I usually use

$(this).css({
    "textAlign":"center",
    "secondCSSProperty":"value" 
});

Hope that helps

If you import os you can use os.getcwd to get the current working directory, and you can use os.chdir to change your directory

With async functions and promises, it now can work as simply as this:

async function foobar() {
  await $("#example").fadeOut().promise();
  doSomethingElse();
  await $("#example").fadeIn().promise();
}

Three libraries for accessing and manipulating dates and times, namely datetime, arrow and pendulum, all make these items available in namedtuples whose elements are accessible either by name or index. Moreover, the items are accessible in precisely the same way. (I suppose if I were more intelligent I wouldn't be surprised.)

>>> YEARS, MONTHS, DAYS, HOURS, MINUTES = range(5)
>>> import datetime
>>> import arrow
>>> import pendulum
>>> [datetime.datetime.now().timetuple()[i] for i in [YEARS, MONTHS, DAYS, HOURS, MINUTES]]
[2017, 6, 16, 19, 15]
>>> [arrow.now().timetuple()[i] for i in [YEARS, MONTHS, DAYS, HOURS, MINUTES]]
[2017, 6, 16, 19, 15]
>>> [pendulum.now().timetuple()[i] for i in [YEARS, MONTHS, DAYS, HOURS, MINUTES]]
[2017, 6, 16, 19, 16]

A variation of the function provided by Paolo Bergantino that works directly on String:

String.prototype.addSlashes = function() 
{ 
   //no need to do (str+'') anymore because 'this' can only be a string
   return this.replace(/[\\"']/g, '\\$&').replace(/\u0000/g, '\\0');
} 

By adding the code above in your library you will be able to do:

var test = "hello single ' double \" and slash \\ yippie";
alert(test.addSlashes());

EDIT:

Following suggestions in the comments, whoever is concerned about conflicts amongst JavaScript libraries can add the following code:

if(!String.prototype.addSlashes)
{
   String.prototype.addSlashes = function()... 
}
else
   alert("Warning: String.addSlashes has already been declared elsewhere.");

I got this error because old server instance was running and using log file, hence new instance was not able to write to log file. Post deleting log file this issue got resolved.

Without installing anything on macOS / most Unix.

Use tidy

cat filename.xml | tidy -xml -iq

Redirecting viewing a file with cat to tidy specifying the file type of xml and to indent while quiet output will suppress error output. JSON also works with -json.

A slight adaptation to the solution above by kingjeffrey for when you want to create and echo the CSV within a template (Ie - most frameworks will have output buffering enabled and you are required to set headers etc in controllers.)

// Create Some data
<?php
    $data = array(
        array( 'row_1_col_1', 'row_1_col_2', 'row_1_col_3' ),
        array( 'row_2_col_1', 'row_2_col_2', 'row_2_col_3' ),
        array( 'row_3_col_1', 'row_3_col_2', 'row_3_col_3' ),
    );


// Create a stream opening it with read / write mode
$stream = fopen('data://text/plain,' . "", 'w+');

// Iterate over the data, writting each line to the text stream
foreach ($data as $val) {
    fputcsv($stream, $val);
}

// Rewind the stream
rewind($stream);

// You can now echo it's content
echo stream_get_contents($stream);

// Close the stream 
fclose($stream);

Credit to Kingjeffrey above and also to this blog post where I found the information about creating text streams.

I got the same error when:

Using a custom ModelView, both Actions (GET and POST) were passing the ModelView that contained two objects:

public ActionResult Add(int? categoryID)
{
    ...
    ProductViewModel productViewModel = new ProductViewModel(
            product,
            rootCategories
            );
    return View(productViewModel); 
}

And the POST also accepting the same model view:

[HttpPost]
[ValidateInput(false)]
public ActionResult Add(ProductModelView productModelView)
{...}

Problem was the View received the ModelView (needed both product and list of categories info), but after submitted was returning only the Product object, but as the POST Add expected a ProductModelView it passed a NULL but then the ProductModelView only constructor needed two parameters(Product, RootCategories), then it tried to find another constructor with no parameters for this NULL case then fails with "no parameterles..."

So, fixing the POST Add as follows correct the problem:

[HttpPost]
[ValidateInput(false)]
public ActionResult Add(Product product)
{...}

Hope this can help somebody (I spent almost half day to find this out!).

As string data types have variable length, it is by default stored as object type. I faced this problem after treating missing values too. Converting all those columns to type 'category' before label encoding worked in my case.

df[cat]=df[cat].astype('category')

And then check df.dtypes and perform label encoding.

The main question was to remove the CR/LF. Using the replace and char functions works for me:

Select replace(replace(Name,char(10),''),char(13),'')

For Postgres or Oracle SQL, use the CHR function instead:

       replace(replace(Name,CHR(10),''),CHR(13),'')

I am kind of surprised that for a simple problem like this there are so many answers that are difficult to read and some, including the chosen one, do not work .

I usually want the result string to be at most maxLen characters. I also use this same function to shorten the slugs in URLs.

str.lastIndexOf(searchValue[, fromIndex]) takes a second parameter that is the index at which to start searching backwards in the string making things efficient and simple.

// Shorten a string to less than maxLen characters without truncating words.
function shorten(str, maxLen, separator = ' ') {
  if (str.length <= maxLen) return str;
  return str.substr(0, str.lastIndexOf(separator, maxLen));
}

This is a sample output:

for (var i = 0; i < 50; i += 3) 
  console.log(i, shorten("The quick brown fox jumps over the lazy dog", i));

 0 ""
 3 "The"
 6 "The"
 9 "The quick"
12 "The quick"
15 "The quick brown"
18 "The quick brown"
21 "The quick brown fox"
24 "The quick brown fox"
27 "The quick brown fox jumps"
30 "The quick brown fox jumps over"
33 "The quick brown fox jumps over"
36 "The quick brown fox jumps over the"
39 "The quick brown fox jumps over the lazy"
42 "The quick brown fox jumps over the lazy"
45 "The quick brown fox jumps over the lazy dog"
48 "The quick brown fox jumps over the lazy dog"

And for the slug:

for (var i = 0; i < 50; i += 10) 
  console.log(i, shorten("the-quick-brown-fox-jumps-over-the-lazy-dog", i, '-'));

 0 ""
10 "the-quick"
20 "the-quick-brown-fox"
30 "the-quick-brown-fox-jumps-over"
40 "the-quick-brown-fox-jumps-over-the-lazy"

To swap characters in a string a of position l and r

    a = a[0:l] + a[r] + a[l+1:r] + a[l] + a[r+1:]
    return a

Example: swap("aaabcccdeee", 3, 7) returns "aaadcccbeee"

In Command prompt go to project folder and execute following:

ng g s servicename

Open a visual command console (Visual Studio Command Prompt)

dumpbin /ARCHIVEMEMBERS openssl.x86.lib

or

lib /LIST openssl.x86.lib

or just open it with 7-zip :) its an AR archive

Use Linq, it is a very quick and easy way.

string mystring = "0, 10, 20, 30, 100, 200";

var query = from val in mystring.Split(',')
            select int.Parse(val);
foreach (int num in query)
{
     Console.WriteLine(num);
}

Firstly, you probably want to add a return false; to the bottom of your Submit() method in JavaScript (so it stops the submit, since you're handling it in AJAX).

You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:

$.ajax({
        type: "POST",
        url: "Default.aspx/OnSubmit",
        data: dataValue,                
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
        },
        success: function (result) {
            alert("We returned: " + result);
        }
    });

Select T.Tamil, T.English, T.Maths, T.Total, Dense_Rank()Over(Order by T.Total Desc) as Std_Rank From (select Tamil,English,Maths,(Tamil+English+Maths) as Total From Student) as T

As others have mentioned the Lint warning is because of the potential memory leak. You can avoid the Lint warning by passing a Handler.Callback when constructing Handler (i.e. you don't subclass Handler and there is no Handler non-static inner class):

Handler mIncomingHandler = new Handler(new Handler.Callback() {
    @Override
    public boolean handleMessage(Message msg) {
        // todo
        return true;
    }
});

As I understand it, this will not avoid the potential memory leak. Message objects hold a reference to the mIncomingHandler object which holds a reference the Handler.Callback object which holds a reference to the Service object. As long as there are messages in the Looper message queue, the Service will not be GC. However, it won't be a serious issue unless you have long delay messages in the message queue.

You could talk your network administrator into setting up a domain for you (say 'evilpuppetmaster.hell') and having the wildcard there so that everything (*.evilpuppetmaster.hell') resolves to your IP

If you are having issues with templates or you are calling the class from another .cpp file

try using '#pragma once' in your header file.

What's wrong with using two regexs (or three)? This makes your intentions more clear and may even improve your performance:

if ($string =~ /^(Clinton|Reagan)/i && $string !~ /Bush/i) { ... }

if (($string =~ /^Clinton/i || $string =~ /^Reagan/i)
        && $string !~ /Bush/i) {
    print "$string\n"
}

This means that you must declare strict mode by writing "use strict" at the beginning of the file or the function to use block-scope declarations.

EX:

function test(){
    "use strict";
    let a = 1;
} 

You can add hidden elements before submitting form.

$('form').submit(function() {
  $(this).find('input[type=checkbox]').each(function (i, el) {
    if(!el.checked) {
      var hidden_el = $(el).clone();
      hidden_el[0].checked = true;
      hidden_el[0].value = '0';
      hidden_el[0].type = 'hidden'
      hidden_el.insertAfter($(el));
    }
  })
});

With Angular CLI, you can use the following command:

ng build --prod

It generates a dist folder with all you need to deploy the application.

If you have no practice with web servers, I recommend you to use Angular to Cloud. You just need to compress the dist folder as zip file and upload it in the platform.

Step-1 Need to find user details by using below query

SQL> select username, account_status from dba_users where username='BOB';

USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            EXPIRED

Step-2 Get users password by using below query.

SQL>SELECT 'ALTER USER '|| name ||' IDENTIFIED BY VALUES '''|| spare4 ||';'|| password ||''';' FROM sys.user$ WHERE name='BOB';

ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';

Step -3 Run Above alter query

SQL> ALTER USER BOB IDENTIFIED BY VALUES 'S:9BDD17811E21EFEDFB1403AAB1DD86AB481E;T:602E36430C0D8DF7E1E453;2F9933095143F432';
User altered.

Step-4 :Check users account status

SQL> select username, account_status from dba_users where username='BOB';
USERNAME                       ACCOUNT_STATUS
------------------------------ --------------------------------
BOB                            OPEN

This answer is based on user3715338's answer (with a small spelling error corrected) and mixed with Michael's answer for Hibernate 3.6 - based on the accepted answer from Brian Deterling. I then extended it (for PostgreSQL) with a couple more types replacing the questionmarks:

public static String toSql(Criteria criteria)
{
    String sql = "";
    Object[] parameters = null;
    try
    {
        CriteriaImpl criteriaImpl = (CriteriaImpl) criteria;
        SessionImpl sessionImpl = (SessionImpl) criteriaImpl.getSession();
        SessionFactoryImplementor factory = sessionImpl.getSessionFactory();
        String[] implementors = factory.getImplementors(criteriaImpl.getEntityOrClassName());
        OuterJoinLoadable persister = (OuterJoinLoadable) factory.getEntityPersister(implementors[0]);
        LoadQueryInfluencers loadQueryInfluencers = new LoadQueryInfluencers();
        CriteriaLoader loader = new CriteriaLoader(persister, factory,
            criteriaImpl, implementors[0].toString(), loadQueryInfluencers);
        Field f = OuterJoinLoader.class.getDeclaredField("sql");
        f.setAccessible(true);
        sql = (String) f.get(loader);
        Field fp = CriteriaLoader.class.getDeclaredField("translator");
        fp.setAccessible(true);
        CriteriaQueryTranslator translator = (CriteriaQueryTranslator) fp.get(loader);
        parameters = translator.getQueryParameters().getPositionalParameterValues();
    }
    catch (Exception e)
    {
        throw new RuntimeException(e);
    }
    if (sql != null)
    {
        int fromPosition = sql.indexOf(" from ");
        sql = "\nSELECT * " + sql.substring(fromPosition);

        if (parameters != null && parameters.length > 0)
        {
            for (Object val : parameters)
            {
                String value = "%";
                if (val instanceof Boolean)
                {
                    value = ((Boolean) val) ? "1" : "0";
                }
                else if (val instanceof String)
                {
                    value = "'" + val + "'";
                }
                else if (val instanceof Number)
                {
                    value = val.toString();
                }
                else if (val instanceof Class)
                {
                    value = "'" + ((Class) val).getCanonicalName() + "'";
                }
                else if (val instanceof Date)
                {
                    SimpleDateFormat sdf = new SimpleDateFormat(
                        "yyyy-MM-dd HH:mm:ss.SSS");
                    value = "'" + sdf.format((Date) val) + "'";
                }
                else if (val instanceof Enum)
                {

                }
                else
                {
                    value = val.toString();
                }
                sql = sql.replaceFirst("\\?", value);
            }
        }
    }
    return sql.replaceAll("left outer join", "\nleft outer join").replaceAll(
        " and ", "\nand ").replaceAll(" on ", "\non ").replaceAll("<>",
        "!=").replaceAll("<", " < ").replaceAll(">", " > ");
}

Try adding this

package.json

devDependencies: {
//...    
    "@react-native-community/cli-debugger-ui": "4.7.0"
}

Terminate everything.

• npm install
• npx react-native start
• npx react-native run-android

I had to go look for ojdbc compatible with version on oracle that was installed this fixed my problem, my bad was thinking one ojdbc would work for all

Pretty close to what the originator was trying to do. Here is a function I use:

def get_arg(index):
    try:
        sys.argv[index]
    except IndexError:
        return ''
    else:
        return sys.argv[index]

So a usage would be something like:

if __name__ == "__main__":
    banner(get_arg(1),get_arg(2))

For api 21+ you can use system image with Google Play as I describe below.

For api 19+ (Android 4.4 Kitkat) you can use system image x86 with Google Api (I was able to use it).

For api 17+ (Android 4.2.2) you can TRY to use system image ARM with Google Api (It didn't work for me).

I was able to install Google Play and Google Services as separate apks to pure system image api 16 and 17, but they don't really work after that (services crush and play not opens). So seems like it is not possible to make them work on pure AVD image because they should be installed with root access. The same for updating Google Services on AVD system image with Google API preinstalled - can't update because of incompatible certificates, can't uninstall even using adb because don't have access.

How to setup AVD system image with Google Play

Now even better solution exist: using AVD image with build-in Google Play Services. It will enable you to use Google Services including Google Play. Also you will be able update it without re-creating AVD image.

Open AVD manager and choose create new device. You should use device definition with play store icon.

Then choose system image for it. You should choose one with Google Play and NOT with Google API.

Then launch new device.

You can update Play Services as shown on screenshot, or manually on device..

For ASP.NET pages I am using the following

BEFORE

<script src="/Scripts/pages/common.js" type="text/javascript"></script>

AFTER (force reload)

 <script src="/Scripts/pages/common.js?ver<%=DateTime.Now.Ticks.ToString()%>" type="text/javascript"></script>

Adding the DateTime.Now.Ticks works very well.

I had this issue when converting an older project to use a new version of Visual Studio. Upon conversion, the project target framework was set to 2.0

I was able to solve this issue by changing the target framework to be 3.5.

FIRST: make sure you have a color as a bitmap, like this:

Bitmap bmp = (Bitmap)pictureBox1.Image.Clone();
paintcolor = bmp.GetPixel(e.X, e.Y);

(e is from the event handler wich picked my color!)

What I did when I had this problem a whilke ago, I first got the rgba (red, green, blue and alpha) values. Next I created 3 floats: float hue, float saturation, float brightness. Then you simply do:

hue = yourcolor.Gethue;
saturation = yourcolor.GetSaturation;
brightness = yourcolor.GetBrightness;

The whole lot looks like this:

Bitmap bmp = (Bitmap)pictureBox1.Image.Clone();
            paintcolor = bmp.GetPixel(e.X, e.Y);
            float hue;
            float saturation;
            float brightness;
            hue = paintcolor.GetHue();
            saturation = paintcolor.GetSaturation();
            brightness = paintcolor.GetBrightness();

If you now want to display them in a label, just do:

yourlabelname.Text = hue.ToString;
yourlabelname.Text = saturation.ToString;
yourlabelname.Text = brightness.ToString;

Here you go, you now have RGB Values into HSV values :)

Hope this helps

I always store my date in UTC time.

This is my own function made from the different functions I found in this page.

It takes a STRING as a mysql DATETIME format (example : 2013-06-15 15:21:41). The checking with the regex is optional. You can delete this part to improve performance.

This function return a timestamp.

The DATETIME is considered as a UTC date. Be carefull : If you expect a local datetime, this function is not for you.

    function datetimeToTimestamp(datetime)
    {
        var regDatetime = /^[0-9]{4}-(?:[0]?[0-9]{1}|10|11|12)-(?:[012]?[0-9]{1}|30|31)(?: (?:[01]?[0-9]{1}|20|21|22|23)(?::[0-5]?[0-9]{1})?(?::[0-5]?[0-9]{1})?)?$/;
        if(regDatetime.test(datetime) === false)
            throw("Wrong format for the param. `Y-m-d H:i:s` expected.");

        var a=datetime.split(" ");
        var d=a[0].split("-");
        var t=a[1].split(":");

        var date = new Date();
        date.setUTCFullYear(d[0],(d[1]-1),d[2]);
        date.setUTCHours(t[0],t[1],t[2], 0);

        return date.getTime();
    }

• Do not use () behind function names in bash unless you like to define them.
• use [23] in case to match 2 or 3
• static string cases should be enclosed by '' instead of ""

If enclosed in "", the interpreter (needlessly) tries to expand possible variables in the value before matching.

case "$C" in
'1')
    do_this
    ;;
[23])
    do_what_you_are_supposed_to_do
    ;;
*)
    do_nothing
    ;;
esac

For case insensitive matching, you can use character classes (like [23]):

case "$C" in

# will match C='Abra' and C='abra'
[Aa]'bra')
    do_mysterious_things
    ;;

# will match all letter cases at any char like `abra`, `ABRA` or `AbRa`
[Aa][Bb][Rr][Aa])
    do_wild_mysterious_things
    ;;

esac

But abra didn't hit anytime because it will be matched by the first case.

If needed, you can omit ;; in the first case to continue testing for matches in following cases too. (;; jumps to esac)

You can use Wget or cURL, see How to download files from command line in Windows like wget or curl.

You will then do e.g.:

wget www.google.com

Ideas from a twisted mind :

class mytwistedclass{
static std::vector<int> initVector;
mytwistedclass()
{
    //initialise with initVector[0] and then delete it :-)
}

};

now set this initVector to something u want to before u instantiate an object. Then your objects are initialized with your parameters.

I just encountered this problem myself and found that Ubuntu 14.04 uses Upstart instead of Systemd, so systemctl commands will not work. This changed in 15.04, so one way around this would be to update your ubuntu install.

If this is not an option for you (it's not for me right now), you need to find the Upstart command that does what you need to do.

For enable, the generic looks to be the following:

update-rc.d <service> enable

Gimp can be used to convert SVGs with primitives (e.g. rects, circles, etc.) into a single path which can be used within HTML5.

1. First download Gimp: https://www.gimp.org/downloads/
2. Export your SVG as a .svg file with any tool of choice e.g. Illustrator. Don't worry if the SVG output is messy for now, Gimp will clean it up
3. Import the SVG file into Gimp with File -> Open, and the following (or similar) dialog should show up:

Check both the Import Paths and Merge imported paths options

4. Then go to Windows->Dockable Dialogues->Paths
5. Right-click on the single path which says Imported Path and you should see the following dialog:

6. Click Export Path... and save this text file to a location of your choice
7. Locate and open up this file with a text editor of your choice e.g Notepad, TextEdit
8. Copy the text within the <path d="copy this text here" />
9. Since Gimp formats the text with lots of spaces, you may need to re-format it, by removing some of the spaces to paste it into your HTML in a single line

As I assess your case is:

• I have a queue of messages (your source for receiving messages, lets name it q111)

• I have multiple consumers, which I would like to do different things with the same message.

Your problem here is while 3 messages are received by this queue, message 1 is consumed by a consumer A, other consumers B and C consumes message 2 and 3. Where as you are in need of a setup where rabbitmq passes on the same copies of all these three messages(1,2,3) to all three connected consumers (A,B,C) simultaneously.

While many configurations can be made to achieve this, a simple way is to use the following two step concept:

• Use a dynamic rabbitmq-shovel to pickup messages from the desired queue(q111) and publish to a fanout exchange (exchange exclusively created and dedicated for this purpose).
• Now re-configure your consumers A,B & C (who were listening to queue(q111)) to listen from this Fanout exchange directly using a exclusive & anonymous queue for each consumer.

Note: While using this concept don't consume directly from the source queue(q111), as messages already consumed wont be shovelled to your Fanout exchange.

If you think this does not satisfies your exact requirement... feel free to post your suggestions :-)

DataFrame['Col_name'].replace("None", np.nan, inplace=True)

 myList.Insert(0, item);

I see that this post is a little out of date but still... I can show you and everyone else (who is in the same situation as I was this day) how i did it.

First of all, you need html like this:

<div class="circle-avatar" style="background-image:url(http://placekitten.com/g/200/400)"></div>

Than your css class will look like this:

div.circle-avatar{
/* make it responsive */
max-width: 100%;
width:100%;
height:auto;
display:block;
/* div height to be the same as width*/
padding-top:100%;

/* make it a circle */
border-radius:50%;

/* Centering on image`s center*/
background-position-y: center;
background-position-x: center;
background-repeat: no-repeat;

/* it makes the clue thing, takes smaller dimension to fill div */
background-size: cover;

/* it is optional, for making this div centered in parent*/
margin: 0 auto;
top: 0;
left: 0;
right: 0;
bottom: 0;
}

It is responsive circle, centered on original image. You can change width and height not to autofill its parent if you want. But keep them equal if you want to have a circle in result.

I hope this answer will help struggling people. Bye.

To get the behavior you want you need to wait for the process to finish before you exit Main(). To be able to tell when your process is done you need to return a Task instead of a void from your function, you should never return void from a async function unless you are working with events.

A re-written version of your program that works correctly would be

class Program {     static void Main(string[] args)     {         Debug.WriteLine("Calling DoDownload");         var downloadTask = DoDownloadAsync();         Debug.WriteLine("DoDownload done");         downloadTask.Wait(); //Waits for the background task to complete before finishing.      }      private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } } 

Because you can not await in Main() I had to do the Wait() function instead. If this was a application that had a SynchronizationContext I would do await downloadTask; instead and make the function this was being called from async.

Using inline styles:

<input type="text" style="text-align: right"/>

or, put it in a style sheet, like so:

<style>
   .rightJustified {
        text-align: right;
    }
</style>

and reference the class:

<input type="text" class="rightJustified"/>

This one copes with spaces on the RHS, and skips 'weird' vars such as bash module definitions (with '()' in them):

echo "# source this to set env vars" > $bld_dir/.env
env | while read line; do
    lhs="${line%%=*}"
    rhs="${line#*=}"
    if [[ "$lhs" =~ ^[0-9A-Za-z_]+$ ]]; then
        echo "export $lhs=\"$rhs\"" >> $bld_dir/.env
    fi
done

SELECT t.name 
  FROM sys.tables AS t
  INNER JOIN sys.schemas AS s
  ON t.[schema_id] = s.[schema_id]
  WHERE s.name = N'schema_name';

I'd probably use a LEFT JOIN, which will return rows even if there's no match, and then you can select only the rows with no match by checking for NULLs.

So, something like:

SELECT V.*
FROM voter V LEFT JOIN elimination E ON V.id = E.voter_id
WHERE E.voter_id IS NULL

Whether that's more or less efficient than using a subquery depends on optimization, indexes, whether its possible to have more than one elimination per voter, etc.

You can escape (this is how this principle is called) the double quotes by prefixing them with another double quote. You can put them in a string as follows:

Dim MyVar as string = "some text ""hello"" "

This will give the MyVar variable a value of some text "hello".

CultureInfo.CurrentCulture.TextInfo.ToTitleCase("hello world");

you need to convert to char first because converting to int adds those days to 1900-01-01

select CONVERT (datetime,convert(char(8),rnwl_efctv_dt ))

here are some examples

select CONVERT (datetime,5)

1900-01-06 00:00:00.000

select CONVERT (datetime,20100101)

blows up, because you can't add 20100101 days to 1900-01-01..you go above the limit

convert to char first

declare @i int
select @i = 20100101
select CONVERT (datetime,convert(char(8),@i))

Run it like this on the command line:

java -jar /path/to/your/jar/jarFile.jar

To refresh the component at regular intervals I found this the best method. In the ngOnInit method setTimeOut function

ngOnInit(): void {
  setTimeout(() => { this.ngOnInit() }, 1000 * 10)
}
//10 is the number of seconds

You can concatenate the strings...

h1.innerHTML += "...I would like to insert a carriage return here...<br />";
h1.innerHTML += "Ant the other line here... <br />";
h1.innerHTML += "And so on...<br />";

jsFiddle.

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

missing data/db folder error

Simply create the folder and you are good to go.

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

If you're not wanting to save changes set savechanges to false

    Sub CloseBook2()
        ActiveWorkbook.Close savechanges:=False
    End Sub

    ActiveWorkbook.Close False

That's yet another question, which, being wrongly put, spawns A LOT of terrible solutions, all making things awfully complicated to solve a non-existent problem.

The extremely simple and obvious rule for any database interaction is

Always select the only data you need.

From this point of view, the question is wrong and the accepted answer is right. But other proposed solutions are just terrible.

The question is "how to get the count wrong way". One should never answer it straightforward, but instead, the only proper answer is "One should never select the rows to count them. Instead, ALWAYS ask the database to count the rows for you." This rule is so obvious, that it's just improbable to see so many tries to break it.

After learning this rule, we would see that this is an SQL question, not even PDO related. And, were it asked properly, from SQL perspective, the answer would appeared in an instant - DISTINCT.

$num = $db->query('SELECT count(distinct boele) FROM tbl WHERE oele = 2')->fetchColumn();

is the right answer to this particular question.

The opening poster's own solution is also acceptable from the perspective of the aforementioned rule, but would be less efficient in general terms.

I suggest merging develop and master with that command

git checkout master

git merge --commit --no-ff --no-edit develop

The following code is what I'm using:

var altKeyDownCount = 0;
window.onkeydown = function (e) {
    if (!e) e = window.event;
    if (e.altKey) {
        altKeyDownCount++;
        if (30 < altKeyDownCount) {
            $('.key').removeClass('hidden');
            altKeyDownCount = 0;
        }
        return false;
    }
}

window.onkeyup = function (e) {
    if (!e) e = window.event;
    altKeyDownCount = 0;
    $('.key').addClass('hidden');
}

When the user keeps holding down the Alt key for some time (about 2 seconds), a group of labels (class='key hidden') appears. When the Alt key is released, the labels disappear. jQuery and Bootstrap are both used.

here is a solution if you are not using jquery:

myArray = myArray.filter(function( obj ) {
  return obj.id !== id;
});

I came across this thread because I was looking for something similar. I like the responses and they gave me some ideas so I tested the .to_hash method and worked really well for the use case too. soo:

I back "Jörg W Mittag" answer: "The Python implementation of DI/IoC is so lightweight that it completely vanishes".

To back up this statement, take a look at the famous Martin Fowler's example ported from Java to Python: Python:Design_Patterns:Inversion_of_Control

As you can see from the above link, a "Container" in Python can be written in 8 lines of code:

class Container:
    def __init__(self, system_data):
        for component_name, component_class, component_args in system_data:
            if type(component_class) == types.ClassType:
                args = [self.__dict__[arg] for arg in component_args]
                self.__dict__[component_name] = component_class(*args)
            else:
                self.__dict__[component_name] = component_class

In PHP, use mysqli_real_escape_string.

Example from the PHP Manual:

<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

mysqli_query($link, "CREATE TEMPORARY TABLE myCity LIKE City");

$city = "'s Hertogenbosch";

/* this query will fail, cause we didn't escape $city */
if (!mysqli_query($link, "INSERT into myCity (Name) VALUES ('$city')")) {
    printf("Error: %s\n", mysqli_sqlstate($link));
}

$city = mysqli_real_escape_string($link, $city);

/* this query with escaped $city will work */
if (mysqli_query($link, "INSERT into myCity (Name) VALUES ('$city')")) {
    printf("%d Row inserted.\n", mysqli_affected_rows($link));
}

mysqli_close($link);
?>

You can simply use setInterval to create such timer in Angular, Use this Code for timer -

timeLeft: number = 60;
  interval;

startTimer() {
    this.interval = setInterval(() => {
      if(this.timeLeft > 0) {
        this.timeLeft--;
      } else {
        this.timeLeft = 60;
      }
    },1000)
  }

  pauseTimer() {
    clearInterval(this.interval);
  }

<button (click)='startTimer()'>Start Timer</button>
<button (click)='pauseTimer()'>Pause</button>

<p>{{timeLeft}} Seconds Left....</p>

Working Example

Another way using Observable timer like below -

import { timer } from 'rxjs';

observableTimer() {
    const source = timer(1000, 2000);
    const abc = source.subscribe(val => {
      console.log(val, '-');
      this.subscribeTimer = this.timeLeft - val;
    });
  }

<p (click)="observableTimer()">Start Observable timer</p> {{subscribeTimer}}

No, functions are not first class objects in java. You can do the same thing by implementing a handler class - this is how callbacks are implemented in the Swing etc.

There are however proposals for closures (the official name for what you're talking about) in future versions of java - Javaworld has an interesting article.

One thing you may want to check is the Rounding Mechanism of Math.Round:

http://msdn.microsoft.com/en-us/library/system.midpointrounding.aspx

Other than that, I recommend the Math.Round(inputNumer, numberOfPlaces) approach over the *100/100 one because it's cleaner.

You may try below code...

$(document).ready(function(){_x000D_
    $('form').find('input[type=text],textarea,select').filter(':visible:first').focus();_x000D_
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>_x000D_
<form>_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
<input type="text" />_x000D_
    _x000D_
<input type="submit" />_x000D_
</form>

Change it to this:

var email = /^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i;

This is a regular expression literal that is passed the i flag which means to be case insensitive.

Keep in mind that email address validation is hard (there is a 4 or 5 page regular expression at the end of Mastering Regular Expressions demonstrating this) and your expression certainly will not capture all valid e-mail addresses.

=(((A1/60)/60)/24)+DATE(1970,1,1)+(-5/24)

assuming A1 is the cell where your time stamp is located and dont forget to adjust to account for the time zone you are in (5 assuming you are on EST)

click WAMP icon -> Apache -> httpd.conf and find listen 80

new versions of WAMP uses

Listen 0.0.0.0:80
Listen [::0]:80

ServerName localhost:80

Change Port Number as you want, like

Listen 0.0.0.0:81
Listen [::0]:81

ServerName localhost:81

and now restart Wamp, thats it

and in web browser type as

http://localhost:81

Introduction

Hi

I was asked this question today in class, and it is a good question! I will explain here and hopefully get my more formal answer reviewed or corrected where it is wrong. :)

Previous Answers

The observation by @Assaf is also correct since binary tree traversal travels recursively to visit each node once.

But!, since it is a recursive algorithm, you often have to use more advanced methods to analyze run-time performance. When dealing with a sequential algorithm or one that uses for-loops, using summations will often be enough. So, what follows is a more detailed explanation of this analysis for those who are curious.

The Recurrence

As previously stated,

T(n) = 2*T(n/2) + 1

where T(n) is the number of operations executed in your traversal algorithm (in-order, pre-order, or post-order makes no difference.

Explanation of the Recurrence

There are two T(n) because inorder, preorder, and postorder traversals all call themselves on the left and right child node. So, think of each recursive call as a T(n). In other words, **left T(n/2) + right T(n/2) = 2 T(n/2) **. The "1" comes from any other constant time operations within the function, like printing the node value, et cetera. (It could honestly be a 1 or any constant number & the asymptotic run-time still computes to the same value. Explanation follows.).

Analysis

This recurrence actually can be analyzed using big theta using the masters' theorem. So, I will apply it here.

T(n) = 2*T(n/2) + constant

where constant is some constant (could be 1 or any other constant).

Using the Masters' Theorem , we have T(n) = a*T(n/b) + f(n).

So, a=2, b=2, f(n) = constant since f(n) = n^c = 1, then it follows that c = 0 since f(n) is a constant.

From here, we can see that a = 2 and b^c = 2 ^0 = 1. So, a>b^c or 2>2^0. So, c < logb(a) or 0 < log2(2)

From here we have T(n) = BigTheta(n^{logb(a)}) = BigTheta(n^1) = BigTheta(n)

If your not famliar with BigTheta(n), it is "similar" ( please bear with me :) ) to O(n) but it is a "tighter bound" or tighter approximation of the run-time. So, BigTheta(n) is both worst-case O(n), and best-case BigOmega(n) run-time.

I hope this helps. Take care.

You can create a search variable to hold your searching criteria. Here is an example using database.

 var query = from o in this.mJDBDataset.Products 
             where o.ProductStatus == textBox1.Text || o.Karrot == textBox1.Text 
             || o.ProductDetails == textBox1.Text || o.DepositDate == textBox1.Text 
             || o.SellDate == textBox1.Text
             select o;

 dataGridView1.DataSource = query.ToList();

 //Search and Calculate
 search = textBox1.Text;
 cnn.Open();
 string query1 = string.Format("select * from Products where ProductStatus='"
               + search +"'");
 SqlDataAdapter da = new SqlDataAdapter(query1, cnn);
 DataSet ds = new DataSet();
 da.Fill(ds, "Products");
 SqlDataReader reader;
 reader = new SqlCommand(query1, cnn).ExecuteReader();

 List<double> DuePayment = new List<double>();

 if (reader.HasRows)
 {

  while (reader.Read())
  {

   foreach (DataRow row in ds.Tables["Products"].Rows)
   {

     DuePaymentstring.Add(row["DuePayment"].ToString());
     DuePayment = DuePaymentstring.Select(x => double.Parse(x)).ToList();

   }
  }

  tdp = 0;
  tdp = DuePayment.Sum();                        
  DuePaymentstring.Remove(Convert.ToString(DuePaymentstring.Count));
  DuePayment.Clear();
 }
 cnn.Close();
 label3.Text = Convert.ToString(tdp + " Due Payment Count: " + 
 DuePayment.Count + " Due Payment string Count: " + DuePaymentstring.Count);
 tdp = 0;
 //DuePaymentstring.RemoveRange(0,DuePaymentstring.Count);
 //DuePayment.RemoveRange(0, DuePayment.Count);
 //Search and Calculate

Here "var query" is generating the search criteria you are giving through the search variable. Then "DuePaymentstring.Select" is selecting the data matching your given criteria. Feel free to ask if you have problem understanding.

I think the following does it semi right. It's been awhile since I've touched C. The idea is to use division since modulus doesn't always give random results. I added 1 to RAND_MAX since there are that many possible values coming from rand including 0. And since the range is also 0 inclusive, I added 1 there too. I think the math is arranged correctly avoid integer math problems.

#define MK_DIVISOR(max) ((int)((unsigned int)RAND_MAX+1/(max+1)))

num = rand()/MK_DIVISOR(65);

I have multiple versions of Java installed, both Sun JDK & JRockit, both 32 bit and 64-bit, etc. and ran into this problem with a fresh install of 64-bit Eclipse for Java EE (JUNO).

What did NOT work:

64-bit trio as suggested by Peter Rader:

I'm using 64-bit Eclipse on 64-bit OS (Windows 7).

I ensured Sun JDK 7 64-bit was the default java version. When I typed "java -version" from command line (cmd.exe), Sun JDK 7 64-bit was returned...

java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)

This did not resolve the problem for me.

What DID work:

Adding -vm option to eclipse.ini as suggested by Jayesh Kavathiya:

I added the following to eclipse.ini:

-vm
C:/apps/java/jdk7-64bit/bin/javaw.exe

Note:

I did not have to uninstall any of the various versions of JDK or JRE I have on my machine.

I know that the question is too old, anyway:

select a, b from mytable group by a, b

will give your all the combinations.

My proposal without ugly "foreach" control structures is

$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));
$allFiles = array_filter(iterator_to_array($iterator), function($file) {
    return $file->isFile();
});

You may only want to extract the filepath, which you can do so by:

array_keys($allFiles);

Still 4 lines of code, but more straight forward than using a loop or something.

As others have suggested, if you have control over whatever code is changing the style of the element you could fire a custom event when you change the element's height:

$('#blah').bind('height-changed',function(){...});
...
$('#blah').css({height:'100px'});
$('#blah').trigger('height-changed');

Otherwise, although pretty resource-intensive, you could set a timer to periodically check for changes to the element's height...

According the to Windows Dev Center WIN32_LEAN_AND_MEAN excludes APIs such as Cryptography, DDE, RPC, Shell, and Windows Sockets.

I think the purpose for regex is much different from indexOf. indexOf simply find the occurance of a certain string while in regex you can use wildcards like [A-Z] which means it will find any capital character in the word without stating the actual character.

Example:

 var index = "This is a string".indexOf("is");_x000D_
 console.log(index);_x000D_
 var length = "This is a string".match(/[a-z]/g).length;_x000D_
 // where [a-z] is a regex wildcard expression thats why its slower_x000D_
 console.log(length);

I included the name of the new App to the INSTALLED_APPS list in the settings.py "before" I issued the startapp command. Once I removed the list entry, I could create the app.

Adding to Jacks solution. I need to Deserialize using the JsonProperty and Serialize while ignoring the JsonProperty (or vice versa). ReflectionHelper and Attribute Helper are just helper classes that get a list of properties or attributes for a property. I can include if anyone actually cares. Using the example below you can serialize the viewmodel and get "Amount" even though the JsonProperty is "RecurringPrice".

    /// <summary>
    /// Ignore the Json Property attribute. This is usefule when you want to serialize or deserialize differently and not 
    /// let the JsonProperty control everything.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    public class IgnoreJsonPropertyResolver<T> : DefaultContractResolver
    {
        private Dictionary<string, string> PropertyMappings { get; set; }

        public IgnoreJsonPropertyResolver()
        {
            this.PropertyMappings = new Dictionary<string, string>();
            var properties = ReflectionHelper<T>.GetGetProperties(false)();
            foreach (var propertyInfo in properties)
            {
                var jsonProperty = AttributeHelper.GetAttribute<JsonPropertyAttribute>(propertyInfo);
                if (jsonProperty != null)
                {
                    PropertyMappings.Add(jsonProperty.PropertyName, propertyInfo.Name);
                }
            }
        }

        protected override string ResolvePropertyName(string propertyName)
        {
            string resolvedName = null;
            var resolved = this.PropertyMappings.TryGetValue(propertyName, out resolvedName);
            return (resolved) ? resolvedName : base.ResolvePropertyName(propertyName);
        }
    }

Usage:

        var settings = new JsonSerializerSettings();
        settings.DateFormatString = "YYYY-MM-DD";
        settings.ContractResolver = new IgnoreJsonPropertyResolver<PlanViewModel>();
        var model = new PlanViewModel() {Amount = 100};
        var strModel = JsonConvert.SerializeObject(model,settings);

Model:

public class PlanViewModel
{

    /// <summary>
    ///     The customer is charged an amount over an interval for the subscription.
    /// </summary>
    [JsonProperty(PropertyName = "RecurringPrice")]
    public double Amount { get; set; }

    /// <summary>
    ///     Indicates the number of intervals between each billing. If interval=2, the customer would be billed every two
    ///     months or years depending on the value for interval_unit.
    /// </summary>
    public int Interval { get; set; } = 1;

    /// <summary>
    ///     Number of free trial days that can be granted when a customer is subscribed to this plan.
    /// </summary>
    public int TrialPeriod { get; set; } = 30;

    /// <summary>
    /// This indicates a one-time fee charged upfront while creating a subscription for this plan.
    /// </summary>
    [JsonProperty(PropertyName = "SetupFee")]
    public double SetupAmount { get; set; } = 0;


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "TypeId")]
    public string Type { get; set; }

    /// <summary>
    /// Billing Frequency
    /// </summary>
    [JsonProperty(PropertyName = "BillingFrequency")]
    public string Period { get; set; }


    /// <summary>
    /// String representing the type id, usually a lookup value, for the record.
    /// </summary>
    [JsonProperty(PropertyName = "PlanUseType")]
    public string Purpose { get; set; }
}

You do not need to use the while True: loop in this case. There is a much simpler way to use the time condition directly:

import time

# timeout variable can be omitted, if you use specific value in the while condition
timeout = 300   # [seconds]

timeout_start = time.time()

while time.time() < timeout_start + timeout:
    test = 0
    if test == 5:
        break
    test -= 1

Setting minifyEnabled to false in my build.gradle file fixed the issue for me.

release {
    minifyEnabled false
}

You should be able to do this if you add in a div (#header below) to wrap your contents of 1.

1. If you float #header, the content from #someid will be forced to flow around it.

2. Next, you set #header's width to 100%. This will make it expand to fill the width of the containing div, #full. This will effectively push all of #someid's content below #header since there is no room to flow around the sides anymore.

3. Finally, set #someid's height to 100%, this will make it the same height as #full.

JSFiddle

HTML

<div id="full">
    <div id="header">Contents of 1</div>
    <div id="someid">Contents of 2</div>
</div>

CSS

html, body, #full, #someid {
  height: 100%;
}

#header {
  float: left;
  width: 100%;
}

Update

I think it's worth mentioning that flexbox is well supported across modern browsers today. The CSS could be altered have #full become a flex container, and #someid should set it's flex grow to a value greater than 0.

html, body, #full {
  height: 100%;
}

#full {
  display: flex;
  flex-direction: column;
}

#someid {
  flex-grow: 1;
}

If you need to resume an scp transfer from local to remote, try with rsync:

rsync --partial --progress --rsh=ssh local_file user@host:remote_file

Short version, as pointed out by @aurelijus-rozenas:

rsync -P -e ssh local_file user@host:remote_file

In general the order of args for rsync is

rsync [options] SRC DEST

It took Microsoft years to identify the gaps and ship an out-of-band CORS module to solve this problem.

1. Install the module from Microsoft
2. Configure it with snippets

as below

<configuration>
    <system.webServer>
        <cors enabled="true" failUnlistedOrigins="true">            
            <add origin="http://*" allowed="true" />
        </cors>
    </system.webServer>
</configuration>

In general, it is much easier than your custom headers and also offers better handling of preflight requests.

In case you need the same for IIS Express, use some PowerShell scripts I wrote.

Initializer block is just like any bits of code; it's not "attached" to any field/method preceding it. To assign values to fields, you have to explicitly use the field as the lhs of an assignment statement.

private int lineCount; {
    try{
        lineCount = LineCounter.countLines(sFileName);
        /*^^^^^^^*/
    }
    catch(IOException ex){
        System.out.println (ex.toString());
        System.out.println("Could not find file " + sFileName);
    }
}

Also, your countLines can be made simpler:

  public static int countLines(String filename) throws IOException {
    LineNumberReader reader  = new LineNumberReader(new FileReader(filename));
    while (reader.readLine() != null) {}
    reader.close();
    return reader.getLineNumber();
  }

Based on my test, it looks like you can getLineNumber() after close().

I found that the direct cause for the error in my case was:

this makes sense since the error is stating that there is an invalid option for language.

but, this was working fine before - so it must've been selected. what changed? turns out a member on my team upgraded to vs 2017, while i was still using 2015. after he made changes to the project, the language version was changed and i received that change over source control. but the version selected was not available to my version of vs, so it was blank - hence the error. after selecting a value in the language drop down (i chose default), a new error popped up. the new error was causing a build failure on any lines of code which used the newer version of c#. i changed the code to perform the same functions, but with my c# version syntax and problem solved.

so while the direct cause of the error was indeed an invalid selection of Language Version, the root cause was due to different vs/c# versions conflicting.

I found this question because I wanted to generate a web page with links to all the websites running on my IIS instance. I used Alexander Shapkin's answer to come up with the following to generate a bunch of links.

$hostname = "localhost"

Foreach ($Site in get-website) {
    Foreach ($Bind in $Site.bindings.collection) {
        $data = [PSCustomObject]@{
            name=$Site.name;
            Protocol=$Bind.Protocol;
            Bindings=$Bind.BindingInformation
        }
        $data.Bindings = $data.Bindings -replace '(:$)', ''
        $html = "<a href=""" + $data.Protocol + "://" + $data.Bindings + """>" + $data.name + "</a>"
        $html.Replace("*", $hostname);
    }
}

Then I paste the results into this hastily written HTML:

<html>
<style>
    a { display: block; }
</style>
{paste PowerShell results here}
</body>
</html>

I was in trouble to import an Enum in typescript

error TS2307: Cannot find module...

What I did to make it work was migrate the enum to another file and make this change:

export enum MyEnum{
    VALUE = "MY_VALUE"
}

to

export enum MyEnum{
    VALUE = 1
}

This parameter is just about whether you are going to use complex html into the tooltip. Set it to true and then hit the html into the title attribute of the tag.

See this fiddle here - I've set the html attribute to true through the data-html="true" in the <a> tag and then just added in the html ad hoc as an example.

Here is 2018 updated solution as described in the Mozilla Development Resources

TO ENCODE FROM UNICODE TO B64

function b64EncodeUnicode(str) {
    // first we use encodeURIComponent to get percent-encoded UTF-8,
    // then we convert the percent encodings into raw bytes which
    // can be fed into btoa.
    return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g,
        function toSolidBytes(match, p1) {
            return String.fromCharCode('0x' + p1);
    }));
}

b64EncodeUnicode('? à la mode'); // "4pyTIMOgIGxhIG1vZGU="
b64EncodeUnicode('\n'); // "Cg=="

TO DECODE FROM B64 TO UNICODE

function b64DecodeUnicode(str) {
    // Going backwards: from bytestream, to percent-encoding, to original string.
    return decodeURIComponent(atob(str).split('').map(function(c) {
        return '%' + ('00' + c.charCodeAt(0).toString(16)).slice(-2);
    }).join(''));
}

b64DecodeUnicode('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"
b64DecodeUnicode('Cg=='); // "\n"

Try this, it's working for me.

Sender:

DataOutputStream dOut = new DataOutputStream(socket.getOutputStream());

dOut.writeInt(message.length); // write length of the message
dOut.write(message);           // write the message

Receiver:

You can obtain all jQuery events using $._data($('[selector]')[0],'events'); change [selector] to what you need.

There is a plugin that gather all events attached by jQuery called eventsReport.

Also i write my own plugin that do this with better formatting.

But anyway it seems we can't gather events added by addEventListener method. May be we can wrap addEventListener call to store events added after our wrap call.

It seems the best way to see events added to an element with dev tools.

But you will not see delegated events there. So there we need jQuery eventsReport.

UPDATE: NOW We CAN see events added by addEventListener method SEE RIGHT ANSWER TO THIS QUESTION.

Considering that we have Set<String> stringSet we can use following:

Plain Java

List<String> strList = new ArrayList<>(stringSet);

Guava

List<String> strList = Lists.newArrayList(stringSet);

Apache Commons

List<String> strList = new ArrayList<>();
CollectionUtils.addAll(strList, stringSet);

Java 10 (Unmodifiable List)

List<String> strList = List.copyOf(stringSet);
List<String> strList = stringSet.stream().collect(Collectors.toUnmodifiableList());

Java 8 (Modifiable Lists)

import static java.util.stream.Collectors.*;
List<String> stringList1 = stringSet.stream().collect(toList());

As per the doc for the method toList()

There are no guarantees on the type, mutability, serializability, or thread-safety of the List returned; if more control over the returned List is required, use toCollection(Supplier).

So if we need a specific implementation e.g. ArrayList we can get it this way:

List<String> stringList2 = stringSet.stream().
                              collect(toCollection(ArrayList::new));

Java 8 (Unmodifiable Lists)

We can make use of Collections::unmodifiableList method and wrap the list returned in previous examples. We can also write our own custom method as:

class ImmutableCollector {
    public static <T> Collector<T, List<T>, List<T>> toImmutableList(Supplier<List<T>> supplier) {
            return Collector.of( supplier, List::add, (left, right) -> {
                        left.addAll(right);
                        return left;
                    }, Collections::unmodifiableList);
        }
}

And then use it as:

List<String> stringList3 = stringSet.stream()
             .collect(ImmutableCollector.toImmutableList(ArrayList::new)); 

Another possibility is to make use of collectingAndThen method which allows some final transformation to be done before returning result:

    List<String> stringList4 = stringSet.stream().collect(collectingAndThen(
      toCollection(ArrayList::new),Collections::unmodifiableList));

One point to note is that the method Collections::unmodifiableList returns an unmodifiable view of the specified list, as per doc. An unmodifiable view collection is a collection that is unmodifiable and is also a view onto a backing collection. Note that changes to the backing collection might still be possible, and if they occur, they are visible through the unmodifiable view. But the collector method Collectors.unmodifiableList returns truly immutable list in Java 10.

The Expires entity-header field gives the date/time after which the response is considered stale.The Cache-control:maxage field gives the age value (in seconds) bigger than which response is consider stale.

Althought above header field give a mechanism to client to decide whether to send request to the server. In some condition, the client send a request to sever and the age value of response is bigger then the maxage value ,dose it means server needs to send the resource to client? Maybe the resource never changed.

In order to resolve this problem, HTTP1.1 gives last-modifided head. The server gives the last modified date of the response to client. When the client need this resource, it will send If-Modified-Since head field to server. If this date is before the modified date of the resouce, the server will sends the resource to client and gives 200 code.Otherwise,it will returns 304 code to client and this means client can use the resource it cached.

Fibonacci heaps

They're used in some of the fastest known algorithms (asymptotically) for a lot of graph-related problems, such as the Shortest Path problem. Dijkstra's algorithm runs in O(E log V) time with standard binary heaps; using Fibonacci heaps improves that to O(E + V log V), which is a huge speedup for dense graphs. Unfortunately, though, they have a high constant factor, often making them impractical in practice.

This is not possible with css. To implement this you will have to use JavaScript (e.g. $("#input").val() == "").

While I see many good Theoretical explanations in the answers mentioned here, I am adding a practical example with an explanation here:

1.

CODE RUN WITHOUT VOLATILE USE

public class VisibilityDemonstration {

private static int sCount = 0;

public static void main(String[] args) {
    new Consumer().start();
    try {
        Thread.sleep(100);
    } catch (InterruptedException e) {
        return;
    }
    new Producer().start();
}

static class Consumer extends Thread {
    @Override
    public void run() {
        int localValue = -1;
        while (true) {
            if (localValue != sCount) {
                System.out.println("Consumer: detected count change " + sCount);
                localValue = sCount;
            }
            if (sCount >= 5) {
                break;
            }
        }
        System.out.println("Consumer: terminating");
    }
}

static class Producer extends Thread {
    @Override
    public void run() {
        while (sCount < 5) {
            int localValue = sCount;
            localValue++;
            System.out.println("Producer: incrementing count to " + localValue);
            sCount = localValue;
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                return;
            }
        }
        System.out.println("Producer: terminating");
    }
}
}

In the above code, there are two threads - Producer and Consumer.

The producer thread iterates over the loop 5 times (with a sleep of 1000 milliSecond or 1 Sec) in between. In every iteration, the producer thread increases the value of sCount variable by 1. So, the producer changes the value of sCount from 0 to 5 in all iterations

The consumer thread is in a constant loop and print whenever the value of sCount changes until the value reaches 5 where it ends.

Both the loops are started at the same time. So both the producer and consumer should print the value of sCount 5 times.

OUTPUT

Consumer: detected count change 0
Producer: incrementing count to 1
Producer: incrementing count to 2
Producer: incrementing count to 3
Producer: incrementing count to 4
Producer: incrementing count to 5
Producer: terminating

ANALYSIS

In the above program, when the producer thread updates the value of sCount, it does update the value of the variable in the main memory(memory from where every thread is going to initially read the value of variable). But the consumer thread reads the value of sCount only the first time from this main memory and then caches the value of that variable inside its own memory. So, even if the value of original sCount in main memory has been updated by the producer thread, the consumer thread is reading from its cached value which is not updated. This is called VISIBILITY PROBLEM .

2.

CODE RUN WITH VOLATILE USE

In the above code, replace the line of code where sCount is declared by the following :

private volatile  static int sCount = 0;

OUTPUT

Consumer: detected count change 0
Producer: incrementing count to 1
Consumer: detected count change 1
Producer: incrementing count to 2
Consumer: detected count change 2
Producer: incrementing count to 3
Consumer: detected count change 3
Producer: incrementing count to 4
Consumer: detected count change 4
Producer: incrementing count to 5
Consumer: detected count change 5
Consumer: terminating
Producer: terminating

ANALYSIS

When we declare a variable volatile, it means that all reads and all writes to this variable or from this variable will go directly into the main memory. The values of these variables will never be cached.

As the value of the sCount variable is never cached by any thread, the consumer always reads the original value of sCount from the main memory(where it is being updated by producer thread). So, In this case the output is correct where both the threads prints the different values of sCount 5 times.

In this way, the volatile keyword solves the VISIBILITY PROBLEM .

Query in Parado's answer is correct, if you want to use MySql too instead GETDATE() you must use (because you've tagged this question with Sql server and Mysql):

select * from tab
where DateCol between adddate(now(),-7) and now() 

$data = array( 
    'name'      => $_POST['name'] , 
    'groupname' => $_POST['groupname'], 
    'age'       => $_POST['age']
);

$this->db->where('id', $_POST['id']);

$this->db->update('tbl_user', $data);

if(window.location.href.indexOf("?added-to-cart=555") >= 0)

It's window.location.href, not window.location.

This might help someone so I'll put my inputs here as well.

I've encountered the same (or similar) problem. Apparently, the problem was the POST request was blocked by Modsec by the following rules: 350147, 340147, 340148, 350148

After blocking the request, I was redirected to the same endpoint but as a GET request of course and thus the 405.

I whitelisted those rules and voila, the 405 error was gone.

Hope this helps someone.

To set up VS code path permanently on Mac OS;

just open .bash_profile using the following command on terminal

open -t .bash_profile

Then add the following path to .bash_profile

code () { VSCODE_CWD="$PWD" open -n -b "com.microsoft.VSCode" --args $* ;}

save the .bash_profile file and quit the terminal. Then reopen the terminal and type code .to open VS code.

to create the profile1.psl file, type in the following command:

new-item $PROFILE.CurrentUserAllHosts -ItemType file -Force

to access the file, type in the next command:

ise $PROFILE.CurrentUserAllHosts

note if you haven't done this before, you will see that you will not be able to run the script because of your execution policy, which you need to change to Unrestricted from Restricted (default).

to do that close the script and then type this command:

Set-ExecutionPolicy -Scope CurrentUser

then:

RemoteSigned

then this command again:

ise $PROFILE.CurrentUserAllHosts

then finally type your aliases in the script, save it, and they should run every time you run powershell, even after restarting your computer.

Opening a pdf using google docs is a bad idea in terms of user experience. It is really slow and unresponsive.

Solution after API 21

Since api 21, we have PdfRenderer which helps converting a pdf to Bitmap. I've never used it but is seems easy enough.

Solution for any api level

Other solution is to download the PDF and pass it via Intent to a dedicated PDF app which will do a banger job displaying it. Fast and nice user experience, especially if this feature is not central in your app.

Use this code to download and open the PDF

public class PdfOpenHelper {

public static void openPdfFromUrl(final String pdfUrl, final Activity activity){
    Observable.fromCallable(new Callable<File>() {
        @Override
        public File call() throws Exception {
            try{
                URL url = new URL(pdfUrl);
                URLConnection connection = url.openConnection();
                connection.connect();

                // download the file
                InputStream input = new BufferedInputStream(connection.getInputStream());
                File dir = new File(activity.getFilesDir(), "/shared_pdf");
                dir.mkdir();
                File file = new File(dir, "temp.pdf");
                OutputStream output = new FileOutputStream(file);

                byte data[] = new byte[1024];
                long total = 0;
                int count;
                while ((count = input.read(data)) != -1) {
                    total += count;
                    output.write(data, 0, count);
                }

                output.flush();
                output.close();
                input.close();
                return file;
            } catch (IOException e) {
                e.printStackTrace();
            }
            return null;
        }
    })
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Subscriber<File>() {
                @Override
                public void onCompleted() {

                }

                @Override
                public void onError(Throwable e) {

                }

                @Override
                public void onNext(File file) {
                    String authority = activity.getApplicationContext().getPackageName() + ".fileprovider";
                    Uri uriToFile = FileProvider.getUriForFile(activity, authority, file);

                    Intent shareIntent = new Intent(Intent.ACTION_VIEW);
                    shareIntent.setDataAndType(uriToFile, "application/pdf");
                    shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                    if (shareIntent.resolveActivity(activity.getPackageManager()) != null) {
                        activity.startActivity(shareIntent);
                    }
                }
            });
}

}

For the Intent to work, you need to create a FileProvider to grant permission to the receiving app to open the file.

Here is how you implement it: In your Manifest:

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">

        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />

    </provider>

Finally create a file_paths.xml file in the resources foler

<?xml version="1.0" encoding="utf-8"?>
<paths>
    <files-path name="shared_pdf" path="shared_pdf"/>
</paths>

Hope this helps =)

Sometimes you really want to set the axes limits before you plot the data. In that case, you can set the "autoscaling" feature of the Axes or AxesSubplot object. The functions of interest are set_autoscale_on, set_autoscalex_on, and set_autoscaley_on.

In your case, you want to freeze the y axis' limits, but allow the x axis to expand to accommodate your data. Therefore, you want to change the autoscaley_on property to False. Here is a modified version of the FFT subplot snippet from your code:

fft_axes = pylab.subplot(h,w,2)
pylab.title("FFT")
fft = scipy.fft(rawsignal)
pylab.ylim([0,1000])
fft_axes.set_autoscaley_on(False)
pylab.plot(abs(fft))

var $form_elements = $("#form_id").find(":input");

All the elements including the submit-button are now in the variable $form_elements.

I had set the new app's application pool to the DefaultAppPool in IIS which obviously is using the Classic pipeline with .NET v.2.0.

To solve the problem I created a new App Pool using the Integrated pipeline and .NET v4.0. just for this new application and then everything started working as expected.

Don't forget to assign this new app pool to the application. Select the application in IIS, click Basic Settings and then pick the new app pool for the app.

As @impulsgraw wrote. You need to check for undefined after the pipes:

<div ng-show="foo || undefined">
    Show this if foo is defined!
</div>
<div ng-show="boo || !undefined">
    Show this if boo is undefined!
</div>

In sleep method you can return any then-able object. and not necessarily a new promise.

example :

const sleep = (t) =>  ({ then: (r) => setTimeout(r, t) })

const someMethod = async () => {

    console.log("hi");
    await sleep(5000)
    console.log("bye");

The accepted answer of how to create an Index inline a Table creation script did not work for me. This did:

CREATE TABLE [dbo].[TableToBeCreated]
(
    [Id] BIGINT IDENTITY(1, 1) NOT NULL PRIMARY KEY
    ,[ForeignKeyId] BIGINT NOT NULL
    ,CONSTRAINT [FK_TableToBeCreated_ForeignKeyId_OtherTable_Id] FOREIGN KEY ([ForeignKeyId]) REFERENCES [dbo].[OtherTable]([Id])
    ,INDEX [IX_TableToBeCreated_ForeignKeyId] NONCLUSTERED ([ForeignKeyId])
)

Remember, Foreign Keys do not create Indexes, so it is good practice to index them as you will more than likely be joining on them.

Just setup angular 4 with webpack 3 within a minute your development and production ENV bundle will become ready without any issue just follow the below github doc

https://github.com/roshan3133/angular2-webpack-starter

You have missed out the field name id in the second NOT LIKE. Try:

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

The AND in the where clause joins 2 full condition expressions such as id NOT LIKE '1%' and can't be used to list multiple values that the id is 'not like'.

Since you tagged the question with javascript and html...

For a purely HTML solution, you can use a meta tag in the header to "refresh" the page, specifying a different URL:

<meta HTTP-EQUIV="REFRESH" content="0; url=http://www.yourdomain.com/somepage.html">

If you can/want to use JavaScript, you can set the location.href of the window:

<script type="text/javascript">
    window.location.href = "http://www.yourdomain.com/somepage.html";
</script>

Another option that may be suitable in this situation is using XML

The XML option to transposing rows into columns is basically an optimal version of the PIVOT in that it addresses the dynamic column limitation. 

The XML version of the script addresses this limitation by using a combination of XML Path, dynamic T-SQL and some built-in functions (i.e. STUFF, QUOTENAME).

Vertical expansion

Similar to the PIVOT and the Cursor, newly added policies are able to be retrieved in the XML version of the script without altering the original script.

Horizontal expansion

Unlike the PIVOT, newly added documents can be displayed without altering the script.

Performance breakdown

In terms of IO, the statistics of the XML version of the script is almost similar to the PIVOT – the only difference is that the XML has a second scan of dtTranspose table but this time from a logical read – data cache.

You can find some more about these solutions (including some actual T-SQL exmaples) in this article: https://www.sqlshack.com/multiple-options-to-transposing-rows-into-columns/

Array.prototype.map() index:

One can access the index Array.prototype.map() via the second argument of the callback function. Here is an example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
_x000D_
const map = array.map((x, index) => {_x000D_
  console.log(index);_x000D_
  return x + index;_x000D_
});_x000D_
_x000D_
console.log(map);

Other arguments of Array.prototype.map():

• The third argument of the callback function exposes the array on which map was called upon
• The second argument of Array.map() is a object which will be the this value for the callback function. Keep in mind that you have to use the regular function keyword in order to declare the callback since an arrow function doesn't have its own binding to the this keyword.

For example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
const thisObj = {prop1: 1}_x000D_
_x000D_
_x000D_
const map = array.map( function (x, index, array) {_x000D_
  console.log(array);_x000D_
  console.log(this)_x000D_
}, thisObj);

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

In the documentation of the version 4.11.x, says: ` "This method is like _.sortBy except that it allows specifying the sort orders of the iteratees to sort by. If orders is unspecified, all values are sorted in ascending order. Otherwise, specify an order of "desc" for descending or "asc" for ascending sort order of corresponding values." (source https://lodash.com/docs/4.17.10#orderBy)

let sorted = _.orderBy(this.items, ['fieldFoo', 'fieldBar'], ['asc', 'desc'])

The compiler prevents you from doing the assignment with Lists:

List<Tiger> myTigersList = new List<Tiger>() { new Tiger(), new Tiger(), new Tiger() };
List<Animal> myAnimalsList = myTigersList;    // Compiler error

But the compiler is perfectly fine with arrays:

Tiger[] myTigersArray = new Tiger[3] { new Tiger(), new Tiger(), new Tiger() };
Animal[] myAnimalsArray = myTigersArray;    // No problem

The argument about whether the assignment is known to be safe falls apart here. The assignment I did with the array is not safe. To prove that, if I follow that up with this:

myAnimalsArray[1] = new Giraffe();

I get a runtime exception "ArrayTypeMismatchException". How does one explain this? If the compiler really wants to prevent me from doing something stupid, it should have prevented me from doing the array assignment.

I think it's important to note another difference between Sort and OrderBy:

Suppose there exists a Person.CalculateSalary() method, which takes a lot of time; possibly more than even the operation of sorting a large list.

Compare

// Option 1
persons.Sort((p1, p2) => Compare(p1.CalculateSalary(), p2.CalculateSalary()));
// Option 2
var query = persons.OrderBy(p => p.CalculateSalary()); 

Option 2 may have superior performance, because it only calls the CalculateSalary method n times, whereas the Sort option might call CalculateSalary up to 2n log(n) times, depending on the sort algorithm's success.

There is no way to do this. Your options are to use a JavaScript or a CSS block.

Maybe there is some JavaScript library that will convert a proprietary style attribute to a style block. But then the code will not be standard-compliant.

You can use CurrentDirectory property.

Dim WshShell, strCurDir
Set WshShell = CreateObject("WScript.Shell")
strCurDir    = WshShell.CurrentDirectory
WshShell.Run strCurDir & "\attribute.exe", 0
Set WshShell = Nothing

The text from the Tortoise reference:

Update item to revision Update your working copy to the selected revision. Useful if you want to have your working copy reflect a time in the past, or if there have been further commits to the repository and you want to update your working copy one step at a time. It is best to update a whole directory in your working copy, not just one file, otherwise your working copy could be inconsistent.

If you want to undo an earlier change permanently, use Revert to this revision instead.

Revert to this revision Revert to an earlier revision. If you have made several changes, and then decide that you really want to go back to how things were in revision N, this is the command you need. The changes are undone in your working copy so this operation does not affect the repository until you commit the changes. Note that this will undo all changes made after the selected revision, replacing the file/folder with the earlier version.

If your working copy is in an unmodified state, after you perform this action your working copy will show as modified. If you already have local changes, this command will merge the undo changes into your working copy.

What is happening internally is that Subversion performs a reverse merge of all the changes made after the selected revision, undoing the effect of those previous commits.

If after performing this action you decide that you want to undo the undo and get your working copy back to its previous unmodified state, you should use TortoiseSVN ? Revert from within Windows Explorer, which will discard the local modifications made by this reverse merge action.

If you simply want to see what a file or folder looked like at an earlier revision, use Update to revision or Save revision as... instead.

You can also find create_tables.sql file it phpMyAdmin's repo. Just import it from phpMyAdmin panel. It should work.

You're using an array of objects. Can you use a two dimensional array instead?

http://www.datatables.net/examples/data_sources/js_array.html

See this jsfiddle: http://jsfiddle.net/QhYse/

I used an array like this and it worked fine:

var data = [
    ["UpdateBootProfile","PASS","00:00:00",[]] ,
    ["NRB Boot","PASS","00:00:50.5000000",[{"TestName":"TOTAL_TURN_ON_TIME","Result":"PASS","Value":"50.5","LowerLimit":"NaN","UpperLimit":"NaN","ComparisonType":"nctLOG","Units":"SECONDS"}]] ,
    ["NvMgrCommit","PASS","00:00:00",[]] ,
    ["SyncNvToEFS","PASS","00:00:01.2500000",[]]
];

Edit to include array of objects

There's a possible solution from this question: jQuery DataTables fnrender with objects

This jsfiddle http://jsfiddle.net/j2C7j/ uses an array of objects. To not get the error I had to pad it with 3 blank values - less than optimal, I know. You may find a better way with fnRender, please post if you do.

var data = [
   ["","","", {"Name":"UpdateBootProfile","Result":"PASS","ExecutionTime":"00:00:00","Measurement":[]} ]

];

$(function() {
        var testsTable = $('#tests').dataTable({
                bJQueryUI: true,
                aaData: data,
                aoColumns: [
                        { mData: 'Name', "fnRender": function( oObj ) { return oObj.aData[3].Name}},
                        { mData: 'Result' ,"fnRender": function( oObj ) { return oObj.aData[3].Result }},
                        { mData: 'ExecutionTime',"fnRender": function( oObj ) { return oObj.aData[3].ExecutionTime } }
                ]
        });
});

Fairly straightforward:

git remote rm origin

As for the filter-branch question - just add --prune-empty to your filter branch command and it'll remove any revision that doesn't actually contain any changes in your resulting repo:

git filter-branch --prune-empty --subdirectory-filter path/to/subtree HEAD

Use another cable.

Just found out that one of my regular charging cables had Vcc, Gnd pairs, but no Data+, Data-.

You just need to post the form data to the insert php file function, see below :)

class DbConnect
{
// Database login vars
private $dbHostname = '';
private $dbDatabase = '';
private $dbUsername = '';
private $dbPassword = '';
public $db = null;

public function connect()
{

    try
    {
        $this->db = new PDO("mysql:host=".$this->dbHostname.";dbname=".$this->dbDatabase, $this->dbUsername, $this->dbPassword);
        $this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    }
    catch(PDOException $e)
    {
        echo "It seems there was an error.  Please refresh your browser and try again. ".$e->getMessage();
    }
}

public function store($email)
{
    $stm = $this->db->prepare('INSERT INTO subscribers (email) VALUES ?');
    $stm->bindValue(1, $email);

    return $stm->execute();
}
}

1. LocalStorage

   Pros:

   1. Web storage can be viewed simplistically as an improvement on cookies, providing much greater storage capacity. If you look at the Mozilla source code we can see that 5120KB (5MB which equals 2.5 Million chars on Chrome) is the default storage size for an entire domain. This gives you considerably more space to work with than a typical 4KB cookie.
   2. The data is not sent back to the server for every HTTP request (HTML, images, JavaScript, CSS, etc) - reducing the amount of traffic between client and server.
   3. The data stored in localStorage persists until explicitly deleted. Changes made are saved and available for all current and future visits to the site.

   Cons:

   1. It works on same-origin policy. So, data stored will only be available on the same origin.

2. Cookies

   Pros:

   1. Compared to others, there's nothing AFAIK.

   Cons:

   1. The 4K limit is for the entire cookie, including name, value, expiry date etc. To support most browsers, keep the name under 4000 bytes, and the overall cookie size under 4093 bytes.

   2. The data is sent back to the server for every HTTP request (HTML, images, JavaScript, CSS, etc) - increasing the amount of traffic between client and server.

      Typically, the following are allowed:

      • 300 cookies in total
      • 4096 bytes per cookie
      • 20 cookies per domain
      • 81920 bytes per domain(Given 20 cookies of max size 4096 = 81920 bytes.)

3. sessionStorage

   Pros:

   1. It is similar to localStorage.
   2. The data is not persistent i.e. data is only available per window (or tab in browsers like Chrome and Firefox). Data is only available during the page session. Changes made are saved and available for the current page, as well as future visits to the site on the same window. Once the window is closed, the storage is deleted.

   Cons:

   1. The data is available only inside the window/tab in which it was set.
   2. Like localStorage, it works on same-origin policy. So, data stored will only be available on the same origin.

Checkout across-tabs - how to facilitate easy communication between cross-origin browser tabs.

Try Calender. Use getInstance to get a Calender-Object. Then use setTime to set the required Date. Now you can use get(int field) with the appropriate constant like HOUR_OF_DAY or so to read the values you need.

From Oracle's java tutorial

import java.net.*;
import java.io.*;

public class URLConnectionReader {
    public static void main(String[] args) throws Exception {
        URL yahoo = new URL("http://www.yahoo.com/");
        URLConnection yc = yahoo.openConnection();
        BufferedReader in = new BufferedReader(
                                new InputStreamReader(
                                yc.getInputStream()));
        String inputLine;

        while ((inputLine = in.readLine()) != null) 
            System.out.println(inputLine);
        in.close();
    }
}

One would use @classmethod when he/she would want to change the behaviour of the method based on which subclass is calling the method. remember we have a reference to the calling class in a class method.

While using static you would want the behaviour to remain unchanged across subclasses

Example:

class Hero:

  @staticmethod
  def say_hello():
     print("Helllo...")

  @classmethod
  def say_class_hello(cls):
     if(cls.__name__=="HeroSon"):
        print("Hi Kido")
     elif(cls.__name__=="HeroDaughter"):
        print("Hi Princess")

class HeroSon(Hero):
  def say_son_hello(self):
     print("test  hello")



class HeroDaughter(Hero):
  def say_daughter_hello(self):
     print("test  hello daughter")


testson = HeroSon()

testson.say_class_hello() #Output: "Hi Kido"

testson.say_hello() #Outputs: "Helllo..."

testdaughter = HeroDaughter()

testdaughter.say_class_hello() #Outputs: "Hi Princess"

testdaughter.say_hello() #Outputs: "Helllo..."

if you use class component then only 3 steps- first you need to declare state for your input filed for example this.state = {name:''}. Secondly, you need to write a function for setting the state when it changes in bellow example it is setName() and finally you have to write the input jsx for example < input value={this.name} onChange = {this.setName}/>

import React, { Component } from 'react'

export class InputComponents extends Component {
    constructor(props) {
        super(props)

        this.state = {
             name:'',
             agree:false
        }
        this.setName = this.setName.bind(this);
        this.setAgree=this.setAgree.bind(this);
    }

    setName(e){
        e.preventDefault();
        console.log(e.target.value);
        this.setState({
            name:e.target.value
        })
    }
    setAgree(){
        this.setState({
            agree: !this.state.agree
        }, function (){
            console.log(this.state.agree);
        })
    }
    render() {
        return (
            <div>
                <input type="checkbox" checked={this.state.agree} onChange={this.setAgree}></input>
                < input value={this.state.name} onChange = {this.setName}/>
            </div>
        )
    }
}

export default InputComponents

Another approach to return a value from an asynchronous function, is to pass in an object that will store the result from the asynchronous function.

Here is an example of the same:

var async = require("async");

// This wires up result back to the caller
var result = {};
var asyncTasks = [];
asyncTasks.push(function(_callback){
    // some asynchronous operation
    $.ajax({
        url: '...',
        success: function(response) {
            result.response = response;
            _callback();
        }
    });
});

async.parallel(asyncTasks, function(){
    // result is available after performing asynchronous operation
    console.log(result)
    console.log('Done');
});

I am using the result object to store the value during the asynchronous operation. This allows the result be available even after the asynchronous job.

I use this approach a lot. I would be interested to know how well this approach works where wiring the result back through consecutive modules is involved.

1. Go to this /etc/postgresql/9.x/main/ and open pg_hba.conf file

In my case:

$>  sudo nano /etc/postgresql/9.3/main/pg_hba.conf

2. Replace peer with md5

So this will be changed to:

Database administrative login by Unix domain socket local all postgres peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     peer
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5

This:

Database administrative login by Unix domain socket local all postgres md5

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket connections only
local   all             all                                     md5
# IPv4 local connections:
host    all             all             127.0.0.1/32            md5

3. Then restart pg server:

   $> sudo service postgresql restart

Below is list of METHODS used to connect with postgres:

# METHOD can be "trust", "reject", "md5", "password", "gss", "sspi",
# "krb5", "ident", "peer", "pam", "ldap", "radius" or "cert".  Note that
# "password" sends passwords in clear text; "md5" is preferred since
# it sends encrypted passwords.

Note: If you have not create you postgres user yet. Create that and now you can access postgres server using that user credentials.

TIP: If it does not work after postgres restart then close terminal and open again.

for those who don't want to see that blink after recreate() method simply use

 finish();
 overridePendingTransition(0, 0);
 startActivity(getIntent());
 overridePendingTransition(0, 0);

another way is to use a css 1x1 background image on option which only seems to work with firefox and have a "----" fallback

<option value="" disabled="disabled" class="SelectSeparator">----</option> 

.SelectSeparator
    {
      background-image:  url(data:image/gif;base64,R0lGODlhAQABAIAAAAAAAAAAACH5BAAAAAAALAAAAAABAAEAAAICTAEAOw==);
      color:black;
      background-repeat:repeat-x;
      background-position:50% 50%;
      background-attachment:scroll;
}

http://jsfiddle.net/yNecQ/6/

or to use javascript (jquery) to:

-hide the select element and 
-show a div which can be completely styled and 
-reflect the div state onto the select for the form submit

http://tutorialzine.com/2010/11/better-select-jquery-css3/

see also How do I add a horizontal line in a html select control?

overflow: auto;
overflow-y: hidden;

For IE8: -ms-overflow-y: hidden;

Or Else :

To hide X:

<div style="height:150x; width:450px; overflow-x:hidden; overflow-y: scroll; padding-bottom:10px;"></div>

To hide Y:

<div style="height:150px; width:450px; overflow-x:scroll ; overflow-y: hidden; padding-bottom:10px;"></div>

That usually means that your friend does not have the Microsoft redistributable for Visual C++. I am of course assuming you are using VC++ and not MingW or another compiler. Since your friend does not have VS installed as well there is no guarantee he has the redist installed.

From a comment:

I want to sort each set.

That's easy. For any set s (or anything else iterable), sorted(s) returns a list of the elements of s in sorted order:

>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']

Note that sorted is giving you a list, not a set. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2} and {2, 1} are the same set.

You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).

The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key function:

>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']

For more information, see the Sorting HOWTO in the official docs.

* See the comments for exceptions.

If you have configured navigation property 1-n I would recommend you to use:

var query = db.Categories                                  // source
   .SelectMany(c=>c.CategoryMaps,                          // join
      (c, cm) => new { Category = c, CategoryMaps = cm })  // project result
   .Select(x => x.Category);                               // select result

Much more clearer to me and looks better with multiple nested joins.

There are a few ways. One of the simplest is to create a my-paths.pth file (as described here). This is just a file with the extension .pth that you put into your system site-packages directory. On each line of the file you put one directory name, so you can put a line in there with /path/to/the/ and it will add that directory to the path.

You could also use the PYTHONPATH environment variable, which is like the system PATH variable but contains directories that will be added to sys.path. See the documentation.

Note that no matter what you do, sys.path contains directories not files. You can't "add a file to sys.path". You always add its directory and then you can import the file.

for (var i in conf) {
  val = conf[i];
  console.log(val.path);
}

just install ojdbc-full, That contains the 12.1.0.1 release.

This approach seems more straightforward, avoiding the need to individually select each file:

# keep remote files
git merge --strategy-option theirs
# keep local files
git merge --strategy-option ours

or

# keep remote files
git pull -Xtheirs
# keep local files
git pull -Xours

Copied directly from: Resolve Git merge conflicts in favor of their changes during a pull

I ran into this also with a file directly in the models directory, and it turns out that I wasn't properly loading up the code on startup. I was able to fix the issue by setting config.eager_load = true in my development.rb file. This made the class available to me in the console

Yes.

$('a[href=\'http://google.com\']')

This is an answer based on jluckyiv's, but I think it is better and simpler to change Javascript as follows.

browser.loadUrl("javascript:HTMLOUT.processHTML(document.documentElement.outerHTML);");

Vinay (above) gave an effective work-around. What's actually causing the button's OnClick event to not work following the OnClientClick event function is that MS has defined it where, once the button is disabled (in the function called by the OnClientClick event), the button "honors" this by not trying to complete the button's activity by calling the OnClick event's defined method.

I struggled several hours trying to figure this out. Once I removed the statement to disable the submit button (that was inside the OnClientClick function), the OnClick method was called with no further problem.

Microsoft, if you're listening, once the button is clicked it should complete it's assigned activity even if it is disabled part of the way through this activity. As long as it is not disabled when it is clicked, it should complete all assigned methods.

You don't need to add extra two classes (button button-primary), you just use the child class (button-primary) with css and it will apply parent as well as child css class. Here is the link:

As far as I know you can only have the same method when using different http methods.

i.e.

[AcceptVerbs("GET")]
public ActionResult MyAction()
{

}

[AcceptVerbs("POST")]
public ActionResult MyAction(FormResult fm)
{

}

Use PDFiumViewer. I searched for a long time till I came up with a similar solution, then I found this clean piece of code that does not rely on sending raw files to the printer (which is bad if they get interpreted as text files..) or using Acrobat or Ghostscript as a helper (both would need to be installed, which is a hassle):

https://stackoverflow.com/a/41751184/586754

PDFiumViewer comes via nuget, the code example above is complete. Pass in null values for using the default printer.

Uninstall:

mysql> uninstall plugin validate_password;

An uninstalled plugin is not displayed by show plugins;

Install:

mysql> install plugin validate_password SONAME 'validate_password.so';

Disabled by configuration:

[mysqld]
validate_password = OFF

A plugin can be disabled by configuration only if installed.
