If you are looking for Hash modification, your solution works ok. However, if you want to change the query, you can use the pushState, as you said. Here it is an example that might help you to implement it properly. I tested and it worked fine:

if (history.pushState) {
    var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?myNewUrlQuery=1';
    window.history.pushState({path:newurl},'',newurl);
}

It does not reload the page, but it only allows you to change the URL query. You would not be able to change the protocol or the host values. And of course that it requires modern browsers that can process HTML5 History API.

For more information:

http://diveintohtml5.info/history.html

https://developer.mozilla.org/en-US/docs/Web/Guide/API/DOM/Manipulating_the_browser_history

You don't make it clear whether you're trying to modify the Querystring in place in the Request object. Since that property is read-only, I guess we'll assume you just want to mess with the string.

... In which case, it's borderline trivial.

• grab the querystring off the Request
• .split() it on '&'
• put it back together into a new string, while sniffing for and tossing out anything starting with "language"

Found this gem from our friends over at SitePoint. https://www.sitepoint.com/url-parameters-jquery/.

Using PURE jQuery. I just used this and it worked. Tweaked it a bit for example sake.

//URL is http://www.example.com/mypage?ref=registration&[email protected]

$.urlParam = function (name) {
    var results = new RegExp('[\?&]' + name + '=([^&#]*)')
                      .exec(window.location.search);

    return (results !== null) ? results[1] || 0 : false;
}

console.log($.urlParam('ref')); //registration
console.log($.urlParam('email')); //[email protected]

Use as you will.

You need to simple use following function.

function GetQueryStringByParameter(name) {
        name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
        var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
        return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
    }

--- How to Use ---

var QueryString= GetQueryStringByParameter('QueryString');

While I know many architectures like ASP.NET MVC have built-in functionality to handle JSON.stringify as the contentType my situation is a little different so maybe this may help someone in the future. I know it would have saved me hours!

Since my http requests are being handled by a CGI API from IBM (AS400 environment) on a different subdomain these requests are cross origin, hence the jsonp. I actually send my ajax via javascript object(s). Here is an example of my ajax POST:

 var data = {USER : localProfile,  
        INSTANCE : "HTHACKNEY",  
        PAGE : $('select[name="PAGE"]').val(), 
        TITLE : $("input[name='TITLE']").val(), 
        HTML : html,
        STARTDATE : $("input[name='STARTDATE']").val(), 
        ENDDATE : $("input[name='ENDDATE']").val(),
        ARCHIVE : $("input[name='ARCHIVE']").val(), 
        ACTIVE : $("input[name='ACTIVE']").val(), 
        URGENT : $("input[name='URGENT']").val(), 
        AUTHLST :  authStr};
        //console.log(data);
       $.ajax({
            type: "POST",
           url:   "http://www.domian.com/webservicepgm?callback=?",
           data:  data,
           dataType:'jsonp'
       }).
       done(function(data){
         //handle data.WHATEVER
       });

$uri_parts = explode('?', $_SERVER['REQUEST_URI'], 2);
$request_uri = $uri_parts[0];
echo $request_uri;

This is what you need :)

The following code will return a JavaScript Object containing the URL parameters:

// Read a page's GET URL variables and return them as an associative array.
function getUrlVars()
{
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
    for(var i = 0; i < hashes.length; i++)
    {
        hash = hashes[i].split('=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
    }
    return vars;
}

For example, if you have the URL:

http://www.example.com/?me=myValue&name2=SomeOtherValue

This code will return:

{
    "me"    : "myValue",
    "name2" : "SomeOtherValue"
}

and you can do:

var me = getUrlVars()["me"];
var name2 = getUrlVars()["name2"];

use encodeURIComponent function to fix url, it works on Browser and node.js

res.redirect("/signin?email="+encodeURIComponent("[email protected]"));


> encodeURIComponent("http://a.com/a+b/c")
'http%3A%2F%2Fa.com%2Fa%2Bb%2Fc'

Percent encoding. Replace the hash with %23.

You can create a new writeable instance of HttpValueCollection by calling System.Web.HttpUtility.ParseQueryString(string.Empty), and then use it as any NameValueCollection. Once you have added the values you want, you can call ToString on the collection to get a query string, as follows:

NameValueCollection queryString = System.Web.HttpUtility.ParseQueryString(string.Empty);

queryString.Add("key1", "value1");
queryString.Add("key2", "value2");

return queryString.ToString(); // Returns "key1=value1&key2=value2", all URL-encoded

The HttpValueCollection is internal and so you cannot directly construct an instance. However, once you obtain an instance you can use it like any other NameValueCollection. Since the actual object you are working with is an HttpValueCollection, calling ToString method will call the overridden method on HttpValueCollection, which formats the collection as a URL-encoded query string.

After searching SO and the web for an answer to a similar issue, this is the most simple solution I could find.

.NET Core

If you're working in .NET Core, you can use the Microsoft.AspNetCore.WebUtilities.QueryHelpers class, which simplifies this greatly.

https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.webutilities.queryhelpers

Sample Code:

const string url = "https://customer-information.azure-api.net/customers/search/taxnbr";
var param = new Dictionary<string, string>() { { "CIKey", "123456789" } };

var newUrl = new Uri(QueryHelpers.AddQueryString(url, param));

You should take a look at the URL API that has helper methods to achieve this in it as the URLSearchParams: https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams

This is not currently supported by all modern browsers, so don't forget to polyfill it (Polyfill available using https://qa.polyfill.io/).

Well, I am using this:

stripUrl(urlToStrip){
        let stripped = urlToStrip.split('?')[0];
        stripped = stripped.split('&')[0];
        stripped = stripped.split('#')[0];
        return stripped;
    }

or:

    stripUrl(urlToStrip){
        return urlToStrip.split('?')[0].split('&')[0].split('#')[0];
    }

req.params contains route parameters (in the path portion of the URL), and req.query contains the URL query parameters (after the ? in the URL).

You can also use req.param(name) to look up a parameter in both places (as well as req.body), but this method is now deprecated.

I like to keep it simple, readable and small.

function searchToObject(search) {
    var pairs = search.substring(1).split("&"),
        obj = {}, pair;

    for (var i in pairs) {
        if (pairs[i] === "") continue;
        pair = pairs[i].split("=");
        obj[decodeURIComponent(pair[0])] = decodeURIComponent(pair[1]);
    }
    return obj;
}

searchToObject(location.search);

Example:

searchToObject('?query=myvalue')['query']; // spits out: 'myvalue'

Doesn't get simpler than this:

<a href="https://twitter.com/intent/tweet?text=optional%20promo%20text%20http://example.com/foo.htm?bar=123&baz=456" target="_blank">Tweet</a>

Different web stacks do support different lengths of http-requests. I know from experience that the early stacks of Safari only supported 4000 characters and thus had difficulty handling ASP.net pages because of the USER-STATE. This is even for POST, so you would have to check the browser and see what the stack limit is. I think that you may reach a limit even on newer browsers. I cannot remember but one of them (IE6, I think) had a limit of 16-bit limit, 32,768 or something.

Some of the comments mention this as well, but asp net core does all this work for you.

If you have a query string that matches the name it will be available in the controller.

https://myapi/some-endpoint/123?someQueryString=YayThisWorks

[HttpPost]
[Route("some-endpoint/{someValue}")]
public IActionResult SomeEndpointMethod(int someValue, string someQueryString)
    {
        Debug.WriteLine(someValue);
        Debug.WriteLine(someQueryString);
        return Ok();
    }

Ouputs:

I ran into a problem with the otherwise wonderful fn_MVParam. SSRS 2005 sent data with an apostrophe as 2 quotes.

I added one line to fix this.

select @RepParam = replace(@RepParam,'''''','''')

My version of the fn also uses varchar instead of nvarchar.

CREATE FUNCTION [dbo].[fn_MVParam]
   (
    @RepParam varchar(MAX),
    @Delim char(1)= ','
   )
RETURNS @Values TABLE (Param varchar(MAX)) AS
/*
  Usage:  Use this in your report SP 
     where ID in (SELECT Param FROM fn_MVParam(@PlanIDList,','))
*/

BEGIN

   select @RepParam = replace(@RepParam,'''''','''')
   DECLARE @chrind INT
   DECLARE @Piece varchar(MAX)
   SELECT @chrind = 1
   WHILE @chrind > 0
      BEGIN
         SELECT @chrind = CHARINDEX(@Delim,@RepParam)
         IF @chrind > 0
            SELECT @Piece = LEFT(@RepParam,@chrind - 1)
         ELSE
            SELECT @Piece = @RepParam
         INSERT @VALUES(Param) VALUES(@Piece)
         SELECT @RepParam = RIGHT(@RepParam,DATALENGTH(@RepParam) - @chrind)
         IF DATALENGTH(@RepParam) = 0 BREAK
      END
   RETURN
END

I had to add [AllowAnonymous] to the ActionResult functions in my login page because the user was not authenticated yet.

This one is simple and worked for me

$.urlParam = function(name){
    var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
    return results[1] || 0;
}

so if your url is http://www.yoursite.com?city=4

try this

console.log($.urlParam('city'));

Every form of the query string retrievable from flask request object as described in O'Reilly Flask Web Devleopment:

From O'Reilly Flask Web Development, and as stated by Manan Gouhari earlier, first you need to import request:

from flask import request

request is an object exposed by Flask as a context variable named (you guessed it) request. As its name suggests, it contains all the information that the client included in the HTTP request. This object has many attributes and methods that you can retrieve and call, respectively.

You have quite a few request attributes which contain the query string from which to choose. Here I will list every attribute that contains in any way the query string, as well as a description from the O'Reilly book of that attribute.

First there is args which is "a dictionary with all the arguments passed in the query string of the URL." So if you want the query string parsed into a dictionary, you'd do something like this:

from flask import request

@app.route('/'):
    queryStringDict = request.args

(As others have pointed out, you can also use .get('<arg_name>') to get a specific value from the dictionary)

Then, there is the form attribute, which does not contain the query string, but which is included in part of another attribute that does include the query string which I will list momentarily. First, though, form is "A dictionary with all the form fields submitted with the request." I say that to say this: there is another dictionary attribute available in the flask request object called values. values is "A dictionary that combines the values in form and args." Retrieving that would look something like this:

from flask import request

@app.route('/'):
    formFieldsAndQueryStringDict = request.values

(Again, use .get('<arg_name>') to get a specific item out of the dictionary)

Another option is query_string which is "The query string portion of the URL, as a raw binary value." Example of that:

from flask import request

@app.route('/'):
    queryStringRaw = request.query_string

Then as an added bonus there is full_path which is "The path and query string portions of the URL." Por ejemplo:

from flask import request

@app.route('/'):
    pathWithQueryString = request.full_path

And finally, url, "The complete URL requested by the client" (which includes the query string):

from flask import request

@app.route('/'):
    pathWithQueryString = request.url

Happy hacking :)

import { useRouter } from 'next/router';

function componentName() {
    const router = useRouter();
    console.log('router obj', router);
}

We can find the query object inside a router using which we can get all query string parameters.

The end to all URL query string editing woes

After lots of toil and fiddling with the Uri class, and other solutions, here're my string extension methods to solve my problems.

using System;
using System.Collections.Specialized;
using System.Linq;
using System.Web;

public static class StringExtensions
{
    public static string AddToQueryString(this string url, params object[] keysAndValues)
    {
        return UpdateQueryString(url, q =>
        {
            for (var i = 0; i < keysAndValues.Length; i += 2)
            {
                q.Set(keysAndValues[i].ToString(), keysAndValues[i + 1].ToString());
            }
        });
    }

    public static string RemoveFromQueryString(this string url, params string[] keys)
    {
        return UpdateQueryString(url, q =>
        {
            foreach (var key in keys)
            {
                q.Remove(key);
            }
        });
    }

    public static string UpdateQueryString(string url, Action<NameValueCollection> func)
    {
        var urlWithoutQueryString = url.Contains('?') ? url.Substring(0, url.IndexOf('?')) : url;
        var queryString = url.Contains('?') ? url.Substring(url.IndexOf('?')) : null;
        var query = HttpUtility.ParseQueryString(queryString ?? string.Empty);

        func(query);

        return urlWithoutQueryString + (query.Count > 0 ? "?" : string.Empty) + query;
    }
}

You can use request.getQueryString(),if the query string is like

username=james&password=pwd

To get name you can do this

request.getParameter("username"); 

@Zugwait's answer is correct. req.param() is deprecated. You should use req.params, req.query or req.body.

But just to make it clearer:

req.params will be populated with only the route values. That is, if you have a route like /users/:id, you can access the id either in req.params.id or req.params['id'].

req.query and req.body will be populated with all params, regardless of whether or not they are in the route. Of course, parameters in the query string will be available in req.query and parameters in a post body will be available in req.body.

So, answering your questions, as color is not in the route, you should be able to get it using req.query.color or req.query['color'].

I just wrote a simple module to deal with reading and updating the current url query params.

Example usage:

import UrlParams from './UrlParams'

UrlParams.remove('foo') //removes all occurences of foo=?
UrlParams.set('foo', 'bar') //set all occurences of foo equal to bar
UrlParams.add('foo', 'bar2') //add bar2 to foo result: foo=bar&foo=bar2
UrlParams.get('foo') //returns bar
UrlParams.get('foo', true) //returns [bar, bar2]

Here is my code named UrlParams.(js/ts):

class UrlParams {

    /**
     * Get params from current url
     * 
     * @returns URLSearchParams
     */
    static getParams(){
        let url = new URL(window.location.href)
        return new URLSearchParams(url.search.slice(1))
    }

    /**
     * Update current url with params
     * 
     * @param params URLSearchParams
     */
    static update(params){
        if(`${params}`){
            window.history.replaceState({}, '', `${location.pathname}?${params}`)
        } else {
            window.history.replaceState({}, '', `${location.pathname}`)
        }
    }

    /**
     * Remove key from url query
     * 
     * @param param string
     */
    static remove(param){
        let params = this.getParams()
        if(params.has(param)){
            params.delete(param)
            this.update(params)
        }
    }

    /**
     * Add key value pair to current url
     * 
     * @param key string
     * @param value string
     */
    static add(key, value){
        let params = this.getParams()
        params.append(key, value)
        this.update(params)
    }

    /**
     * Get value or values of key
     * 
     * @param param string
     * @param all string | string[]
     */
    static get(param, all=false){
        let params = this.getParams()
        if(all){
            return params.getAll(param)
        }
        return params.get(param)
    }

    /**
     * Set value of query param
     * 
     * @param key string
     * @param value string
     */
    static set(key, value){
        let params = this.getParams()
        params.set(key, value)
        this.update(params)
    }

}
export default UrlParams
export { UrlParams }

Here's the technical answer (expanding on Rowland Shaw's answer).

The Is keyword checks whether the two operands are references to the same object memory, and only returns true if this is the case. I believe it is functionally equivalent to Object.ReferenceEquals. The IsNot keyword is simply shorthand syntax for writing Not ... Is ..., nothing more.

The = (equality) operator compares values and in this case (as in many others) is equivalent to String.Equals. Now, the <> (inequality) operator does not quite have the same analogy as the Is and IsNot keywords, since it can be overriden separately from the = operator depending on the class. I believe the case should always be that it returns the logical inverse of the = operator (and certainly is in the case of String), and just allows for a more efficient comparison to made when testing for inequality rather than equality.

When dealing with strings, unless you actually mean to compare references, always use the = operator (or String.Equals I suppose). In your case, because you are testing for null (Nothing), it seems you need to use the Is or IsNot keyword (the equality operator will fail because it can't compare the values of null objects). Syntactically, the IsNot keyword is a bit nicer here, so go with that.

The query component is indicated by the first ? in a URI. "Query string" might be a synonym (this term is not used in the URI standard).

Some examples for HTTP URIs with query components:

http://example.com/foo?bar
http://example.com/foo/foo/foo?bar/bar/bar
http://example.com/?bar
http://example.com/?@bar._=???/1:
http://example.com/?bar1=a&bar2=b

(list of allowed characters in the query component)

The "format" of the query component is up to the URI authors. A common convention (but nothing more than a convention, as far as the URI standard is concerned¹) is to use the query component for key-value pairs, aka. parameters, like in the last example above: bar1=a&bar2=b.

Such parameters could also appear in the other URI components, i.e., the path² and the fragment. As far as the URI standard is concerned, it’s up to you which component and which format to use.

Example URI with parameters in the path, the query, and the fragment:

http://example.com/foo;key1=value1?key2=value2#key3=value3

¹ The URI standard says about the query component:

[…] query components are often used to carry identifying information in the form of "key=value" pairs […]

² The URI standard says about the path component:

[…] the semicolon (";") and equals ("=") reserved characters are often used to delimit parameters and parameter values applicable to that segment. The comma (",") reserved character is often used for similar purposes.

You can rather pass your arguments using this encodeURIComponent function so you don't have to worry about passing any special characters.

data: "param1=getAccNos&param2="+encodeURIComponent('Dolce & Gabbana') OR
var someValue = 'Dolce & Gabbana';
data : "param1=getAccNos&param2="+encodeURIComponent(someValue)

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/encodeURIComponent

I don't think there's a standard.
Each web environment provides its own 'standard' for such things. Besides, the url is usually too short for anything (256 bytes limit on some browsers). Of course longer arrays/data can be send with POST requests.

However, there are some methods:

1. There's a PHP way, which uses square brackets ([,]) in URL queries. For example a query such as ?array_name[]=item&array_name[]=item_2 has been said to work, despite being poorly documented, with PHP automatically converting it into an array. Source: https://stackoverflow.com/a/9547490/3787376

2. Object data-interchange formats (e.g. JSON - official website, PHP documentation) can also be used if they have methods of converting variables to and from strings as JSON does.
   Also an url-encoder (available for most programming languages) is required for HTTP get requests to encode the string data correctly.

Although the "square brackets method" is simple and works, it is limited to PHP and arrays.
If other types of variable such as classes or passing variables within query strings in a language other than PHP is required, the JSON method is recommended.

Example in PHP of JSON method (method 2):

$myarray = array(2, 46, 34, "dfg");
$serialized = json_encode($myarray)
$data = 'myarray=' . rawurlencode($serialized);
// Send to page via cURL, header() or other service.

Code for receiving page (PHP):

$myarray = json_decode($_GET["myarray"]); // Or $_POST["myarray"] if a post request.

This issue has been fixed in the regular release of MVC4. Now you can do:

public string GetFindBooks(string author="", string title="", string isbn="", string  somethingelse="", DateTime? date= null) 
{
    // ...
}

and everything will work out of the box.

You can change the URL with:

window.history.pushState({}, document.title, window.location.pathname);

this way, you can overwrite the URL without the search parameter, I use it to clean the URL after take the GET parameters.

Here's a concise & recursive version with Object.entries. It handles arbitrarily nested arrays, but not nested objects. It also removes empty elements:

const format = (k,v) => v !== null ? `${k}=${encodeURIComponent(v)}` : ''

const to_qs = (obj) => {
    return [].concat(...Object.entries(obj)
                       .map(([k,v]) => Array.isArray(v) 
                          ? v.map(arr => to_qs({[k]:arr})) 
                          : format(k,v)))
           .filter(x => x)
           .join('&');
}

E.g.:

let json = { 
    a: [1, 2, 3],
    b: [],              // omit b
    c: 1,
    d: "test&encoding", // uriencode
    e: [[4,5],[6,7]],   // flatten this
    f: null,            // omit nulls
    g: 0
};

let qs = to_qs(json)

=> "a=1&a=2&a=3&c=1&d=test%26encoding&e=4&e=5&e=6&e=7&g=0"

Also if you are looking for current file name along with the query string, you will just need following

basename($_SERVER['REQUEST_URI'])

It would provide you info like following example

file.php?arg1=val&arg2=val

And if you also want full path of file as well starting from root, e.g. /folder/folder2/file.php?arg1=val&arg2=val then just remove basename() function and just use fillowing

$_SERVER['REQUEST_URI']

If you're using jQuery, you can use a library, such as jQuery BBQ: Back Button & Query Library.

...jQuery BBQ provides a full .deparam() method, along with both hash state management, and fragment / query string parse and merge utility methods.

Edit: Adding Deparam Example:

 var DeparamExample = function() {_x000D_
            var params = $.deparam.querystring();_x000D_
_x000D_
            //nameofparam is the name of a param from url_x000D_
            //code below will get param if ajax refresh with hash_x000D_
            if (typeof params.nameofparam == 'undefined') {_x000D_
                params = jQuery.deparam.fragment(window.location.href);_x000D_
            }_x000D_
            _x000D_
            if (typeof params.nameofparam != 'undefined') {_x000D_
                var paramValue = params.nameofparam.toString();_x000D_
                  _x000D_
            }_x000D_
        };

If you want to just use plain JavaScript, you could use...

var getParamValue = (function() {

})();?

Because of the new HTML History API and specifically history.pushState() and history.replaceState(), the URL can change which will invalidate the cache of parameters and their values.

This version will update its internal cache of parameters each time the history changes.

SQLite does not contain regular expression functionality by default.

It defines a REGEXP operator, but this will fail with an error message unless you or your framework define a user function called regexp(). How you do this will depend on your platform.

If you have a regexp() function defined, you can match an arbitrary integer from a comma-separated list like so:

... WHERE your_column REGEXP "\b" || your_integer || "\b";

But really, it looks like you would find things a whole lot easier if you normalised your database structure by replacing those groups within a single column with a separate row for each number in the comma-separated list. Then you could not only use the = operator instead of a regular expression, but also use more powerful relational tools like joins that SQL provides for you.

Below words come from the official document.

Form contains the parsed form data, including both the URL field's query parameters and the POST or PUT form data. This field is only available after ParseForm is called.

So, sample codes as below would work.

func parseRequest(req *http.Request) error {
    var err error

    if err = req.ParseForm(); err != nil {
        log.Error("Error parsing form: %s", err)
        return err
    }

    _ = req.Form.Get("xxx")

    return nil
}

Purpose: The URL path name of the current PHP file, path-info is N/A and excluding URL query string. Includes leading slash.

Caveat: This is before URL rewrites (i.e. it's as per the original call URL).

Caveat: Not set on all PHP environments, and definitely only ones with URL rewrites.

I had this problem while inheriting from ApiController instead of the regular Controller class. I solved it by using var container = Request.GetQueryNameValuePairs().ToLookup(x => x.Key, x => x.Value);

I followed this thread How to get Request Querystring values?

EDIT: After trying to filter through the container I was getting odd error messages. After going to my project properties and I unchecked the Optimize Code checkbox which changed so that all of a sudden the parameters in my controller where filled up from the url as I wanted.

Hopefully this will help someone with the same problem..

HttpUtility.ParseQueryString will work as long as you are in a web app or don't mind including a dependency on System.Web. Another way to do this is:

NameValueCollection queryParameters = new NameValueCollection();
string[] querySegments = queryString.Split('&');
foreach(string segment in querySegments)
{
   string[] parts = segment.Split('=');
   if (parts.Length > 0)
   {
      string key = parts[0].Trim(new char[] { '?', ' ' });
      string val = parts[1].Trim();

      queryParameters.Add(key, val);
   }
}

<?php

$lurl=get_fcontent("http://ip2.cc/?api=cname&ip=84.228.229.81");
echo"cid:".$lurl[0]."<BR>";


function get_fcontent( $url,  $javascript_loop = 0, $timeout = 5 ) {
    $url = str_replace( "&amp;", "&", urldecode(trim($url)) );

    $cookie = tempnam ("/tmp", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt( $ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );

Here is a fast and easy way of parsing query strings in JavaScript:

function getQueryVariable(variable) {
    var query = window.location.search.substring(1);
    var vars = query.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        if (decodeURIComponent(pair[0]) == variable) {
            return decodeURIComponent(pair[1]);
        }
    }
    console.log('Query variable %s not found', variable);
}

Now make a request to page.html?x=Hello:

console.log(getQueryVariable('x'));

For a quick non-JQuery function...

function jsonToQueryString(json) {
    return '?' + 
        Object.keys(json).map(function(key) {
            return encodeURIComponent(key) + '=' +
                encodeURIComponent(json[key]);
        }).join('&');
}

Note this doesn't handle arrays or nested objects.

I learned from the other answers and decided to use this code throughout my site:

var query = require('url').parse(req.url,true).query;

Then you can just call

var id = query.id;
var option = query.option;

where the URL for get should be

/path/filename?id=123&option=456

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

• hash based routing (@cmfolio)
• array parameters (@user2368055)
• proper use of decodeURIComponent and non-encoded = (@AndrewF)
• non-encoded + (added by me)

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;
  var question = url.indexOf("?");
  var hash = url.indexOf("#");
  if(hash==-1 && question==-1) return {};
  if(hash==-1) hash = url.length;
  var query = question==-1 || hash==question+1 ? url.substring(hash) : 
  url.substring(question+1,hash);
  var result = {};
  query.split("&").forEach(function(part) {
    if(!part) return;
    part = part.split("+").join(" "); // replace every + with space, regexp-free version
    var eq = part.indexOf("=");
    var key = eq>-1 ? part.substr(0,eq) : part;
    var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
    var from = key.indexOf("[");
    if(from==-1) result[decodeURIComponent(key)] = val;
    else {
      var to = key.indexOf("]",from);
      var index = decodeURIComponent(key.substring(from+1,to));
      key = decodeURIComponent(key.substring(0,from));
      if(!result[key]) result[key] = [];
      if(!index) result[key].push(val);
      else result[key][index] = val;
    }
  });
  return result;
}

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c
  [x] : b
*/

Here's my slightly different approach to this, written as an excercise

function addOrChangeParameters( url, params )
{
  let splitParams = {};
  let splitPath = (/(.*)[?](.*)/).exec(url);
  if ( splitPath && splitPath[2] )
    splitPath[2].split("&").forEach( k => { let d = k.split("="); splitParams[d[0]] = d[1]; } );
  let newParams = Object.assign( splitParams, params );
  let finalParams = Object.keys(newParams).map( (a) => a+"="+newParams[a] ).join("&");
  return splitPath ? (splitPath[1] + "?" + finalParams) : (url + "?" + finalParams);
}

usage:

const url = "http://testing.com/path?empty&value1=test&id=3";

addOrChangeParameters( url, {value1:1, empty:"empty", new:0} )

"http://testing.com/path?empty=empty&value1=1&id=3&new=0"

The accepted answer is good. To extend on the last part:

Note that encodeURIComponent does not escape the ' character. A common bug is to use it to create html attributes such as href='MyUrl', which could suffer an injection bug. If you are constructing html from strings, either use " instead of ' for attribute quotes, or add an extra layer of encoding (' can be encoded as %27).

If you want to be on the safe side, percent encoding unreserved characters should be encoded as well.

You can use this method to escape them (source Mozilla)

function fixedEncodeURIComponent(str) {
  return encodeURIComponent(str).replace(/[!'()*]/g, function(c) {
    return '%' + c.charCodeAt(0).toString(16);
  });
}

// fixedEncodeURIComponent("'") --> "%27"

Try like this.It should work

Response.Redirect(String.Format("yourpage.aspx?strId={0}&strName={1}&strDate{2}", Server.UrlEncode(strId), Server.UrlEncode(strName),Server.UrlEncode(strDate)));

If you don't want use external package , Just add the following function in your utilities :

var params=function(req){
  let q=req.url.split('?'),result={};
  if(q.length>=2){
      q[1].split('&').forEach((item)=>{
           try {
             result[item.split('=')[0]]=item.split('=')[1];
           } catch (e) {
             result[item.split('=')[0]]='';
           }
      })
  }
  return result;
}

Then , in createServer call back , add attribute params to request object :

 http.createServer(function(req,res){
     req.params=params(req); // call the function above ;
      /**
       * http://mysite/add?name=Ahmed
       */
     console.log(req.params.name) ; // display : "Ahmed"

})

This is the most basic version I can think of:

public function implode_key($glue = "", $pieces = array())
{
    $keys = array_keys($pieces);
    return implode($glue, $keys);
}

I don't agree with the statement about [...] HTTP referrer leakage (an external image in the target page might leak the password) in Slough's response.

The HTTP 1.1 RFC explicitly states:

Clients SHOULD NOT include a Referer header field in a (non-secure) HTTP request if the referring page was transferred with a secure protocol.

Anyway, server logs and browser history are more than sufficient reasons not to put sensitive data in the query string.

The API docs on link_to show some examples of adding querystrings to both named and oldstyle routes. Is this what you want?

link_to can also produce links with anchors or query strings:

link_to "Comment wall", profile_path(@profile, :anchor => "wall")
#=> <a href="/profiles/1#wall">Comment wall</a>

link_to "Ruby on Rails search", :controller => "searches", :query => "ruby on rails"
#=> <a href="/searches?query=ruby+on+rails">Ruby on Rails search</a>

link_to "Nonsense search", searches_path(:foo => "bar", :baz => "quux")
#=> <a href="/searches?foo=bar&amp;baz=quux">Nonsense search</a>

function getURLParameter(name) {
    return decodeURI(
        (RegExp(name + '=' + '(.+?)(&|$)').exec(location.search)||[,null])[1]
    );
}

Just use a COUNTIF ! Much faster to write and calculate than the other suggestions.

EDIT:

Say you cell A1 should be 1 if the value of B1 is found in column C and otherwise it should be 2. How would you do that?

I would say if the value of B1 is found in column C, then A1 will be positive, otherwise it will be 0. Thats easily done with formula: =COUNTIF($C$1:$C$15,B1), which means: count the cells in range C1:C15 which are equal to B1.

You can combine COUNTIF with VLOOKUP and IF, and that's MUCH faster than using 2 lookups + ISNA. IF(COUNTIF(..)>0,LOOKUP(..),"Not found")

A bit of Googling will bring you tons of examples.

declare @newdata varchar(30)
set @newdata='IDS_ENUM_Change_262147_190'
select REVERSE(substring(reverse(@newdata),0,charindex('_',reverse(@newdata))))

=== Explanation ===

I found it easier to read written like this:

SELECT
    REVERSE( --4.
        SUBSTRING( -- 3.
            REVERSE(<field_name>),
            0,
            CHARINDEX( -- 2.
                '<your char of choice>',
                REVERSE(<field_name>) -- 1.
            )
        )
    )
FROM
    <table_name>

1. Reverse the text
2. Look for the first occurrence of a specif char (i.e. first occurrence FROM END of text). Gets the index of this char
3. Looks at the reversed text again. searches from index 0 to index of your char. This gives the string you are looking for, but in reverse
4. Reversed the reversed string to give you your desired substring

In PHP 5 you can use SoapClient on the WSDL to call the web service functions. For example:

$client = new SoapClient("some.wsdl");

and $client is now an object which has class methods as defined in some.wsdl. So if there was a method called getTime in the WSDL then you would just call:

$result = $client->getTime();

And the result of that would (obviously) be in the $result variable. You can use the __getFunctions method to return a list of all the available methods.

Use numpy.asarray:

import numpy as np
myarray = np.asarray(mylist)

If you are averse to boost, you can use regular old operator>>, along with std::noskipws:

EDIT: updates after testing.

#include <iostream>
#include <iomanip>
#include <vector>
#include <string>
#include <algorithm>
#include <iterator>
#include <sstream>

void split(const std::string& str, std::vector<std::string>& v) {
  std::stringstream ss(str);
  ss >> std::noskipws;
  std::string field;
  char ws_delim;
  while(1) {
    if( ss >> field )
      v.push_back(field);
    else if (ss.eof())
      break;
    else
      v.push_back(std::string());
    ss.clear();
    ss >> ws_delim;
  }
}

int main() {
  std::vector<std::string> v;
  split("hello world  how are   you", v);
  std::copy(v.begin(), v.end(), std::ostream_iterator<std::string>(std::cout, "-"));
  std::cout << "\n";
}

Because the designers of CSS didn't have the foresight to imagine the flexibility this would bring. There are plenty of reasons to expand the content area of a box without affecting its relationship to neighbouring elements. If you think it's not possible, put some long nowrap'd text in a box, set a width on the box, and watch how the overflowed content does nothing to the layout.

Yes, this is still relevant with CSS3 in 2019; case in point: flexbox layouts. Flexbox items' margins do not collapse, so in order to space them evenly and align them with the visual edge of the container, one must subtract the items' margins from their container's padding. If any result is < 0, you must use a negative margin on the container, or sum that negative with the existing margin. I.e. the content of the element effects how one defines the margins for it, which is backwards. Summing doesn't work cleanly when flex elements' content have margins defined in different units or are affected by a different font-size, etc.

The example below should, ideally have aligned and evenly spaced grey boxes but, sadly they aren't.

I have encountered enough of these little issues over the years where a little negative padding would have gone a long way, but instead I'm forced to add non-semantic markup, use calc(), or CSS preprocessors which only work when the units are the same, etc.

Here's another:

data[data$Code == "A" | data$Code == "B", ]

It's also worth mentioning that the subsetting factor doesn't have to be part of the data frame if it matches the data frame rows in length and order. In this case we made our data frame from this factor anyway. So,

data[Code == "A" | Code == "B", ]

also works, which is one of the really useful things about R.

I'd use something like:

dim customer = (from c in xmldoc...<Customer> 
                where c.<ID>.Value=22 
                select c).SingleOrDefault 

Edit:

missed the c# tag, sorry......the example is in VB.NET

I seem to recall having to use @GeneratedValue(strategy = GenerationType.IDENTITY) to get Hibernate to use 'serial' columns on PostgreSQL.

You can easily make SSH connections using SSHLibrary. Read this post :

https://workpython.blogspot.com/2020/04/creating-ssh-connections-with-python.html

Use json_decode to transform your JSON into a PHP array. Example:

$json = '{"a":"b"}';
$array = json_decode($json, true);
echo $array['a']; // b

Now it is possible to install openjdk-11 this way:

sudo apt-get install openjdk-11-jdk

(Previously it installed openjdk-10, but not anymore)

{PowerManager mgr = (PowerManager)context.getSystemService(Context.POWER_SERVICE);
WakeLock wakeLock = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"MyWakeLock"); 
wakeLock.acquire();}

use this code and don't forget to permit wakelock in android manifest

In Spyder one can configure the IPython console for each Python file to clear all variables before each execution in the Menu Run -> Configuration -> General settings -> Remove all variables before execution.

Specify the optional selector to target what you want:

jQuery(this).parent('li').addClass('yourClass');

Or:

jQuery(this).parents('li').addClass('yourClass');

Also possible like this

<button type="submit" class="icon-search icon-large"></button>

The strpos() finds the offset of the underscore, then substr grabs everything from that index plus 1, onwards.

$data = "123_String";    
$whatIWant = substr($data, strpos($data, "_") + 1);    
echo $whatIWant;

If you also want to check if the underscore character (_) exists in your string before trying to get it, you can use the following:

if (($pos = strpos($data, "_")) !== FALSE) { 
    $whatIWant = substr($data, $pos+1); 
}

Assuming ASCII strings:

string1 = 'Hello'
string2 = 'hello'

if string1.lower() == string2.lower():
    print("The strings are the same (case insensitive)")
else:
    print("The strings are NOT the same (case insensitive)")

By reading online (tables tutorial) it seems tables behave like arrays so you're looking for:

Way1

names = {'John', 'Joe', 'Steve'}
for i = 1,3 do print( names[i] ) end

Way2

names = {'John', 'Joe', 'Steve'}
for k,v in pairs(names) do print(v) end

Way1 uses the table index/key , on your table names each element has a key starting from 1, for example:

names = {'John', 'Joe', 'Steve'}
print( names[1] ) -- prints John

So you just make i go from 1 to 3.

On Way2 instead you specify what table you want to run and assign a variable for its key and value for example:

names = {'John', 'Joe', myKey="myValue" }
for k,v in pairs(names) do print(k,v) end

prints the following:

1   John
2   Joe
myKey   myValue

One way to do it must be if (typeof myObj.prop1 != "undefined") {...}

Here's a JSFiffle without JQuery

    var xmlhttp = new XMLHttpRequest();
    var url = 'http://echo.jsontest.com/key/value/one/two';

    xmlhttp.onreadystatechange = function () {

            } else if (xmlhttp.status == 400) {
                console.log('There was an error 400');
            } else {
                console.log('something else other than 200 was returned');

If you want to dump all collections, run this command:

mongodump -d {DB_NAME}   -o /tmp 

It will generate all collections data in json and bson extensions into /tmp/{DB_NAME} directory

function relativepath($to){
    $a=explode("/",$_SERVER["PHP_SELF"] );
    $index= array_search("$to",$a);
    $str=""; 
    for ($i = 0; $i < count($a)-$index-2; $i++) {
        $str.= "../";
    }
    return $str;
    }

Here is the best solution i made about that, you just need to specify at which level you want to stop, but the problem is that you have to use this folder name one time.

This question is very helpfully BUT Don't forget to mount SD Card in your emulator, if you don't do this its doesn't work.

I lose my time before discover this.

Standard SQL provides the MERGE statement for this task. Not all DBMS support the MERGE statement.

Containment :- Here to access inner object we have to use outer object. We can reuse the contained object. Aggregation :- Here we can access inner object again and again without using outer object.

Only an addition to the above responses: A possibility in such cases is that you are calling an object, that for some reason is not available to your query. For example you may subset by row names or column names, and you will receive this error message when your requested row or column is not part of the data matrix or data frame anymore. Solution: As a short version of the responses above: you need to find the last working row name or column name, and the next called object should be the one that could not be found. If you run parallel codes like "foreach", then you need to convert your code to a for loop to be able to troubleshoot it.

It can be something as simple as typing the package name in the wrong case...

I had the same problem - turned out I was entering the package name in all lower case when the actual package name included upper case characters.

adb uninstall -k <packageName - eg. com.test.app>

( If you're explicitly uninstalling you probably don't want the -k which keeps the app data and cache directories around. )

Adding these two lines fixed this problem for me

"responsive": true,
"bAutoWidth": true

There is now a responsive plugin available: https://datatables.net/extensions/responsive/. However, in my experience I have found that there are still a few bugs. It's still the best solution I've found so far.

Intents are intense.

Intents are useful for passing data around the android framework. You can communicate with your own Activities and even other processes. Check the developer guide and if you have specific questions (it's a lot to digest up front) come back.

Here is an example why duck typing is evil without knowing when it is dangerous. For instance: Here is the Python code (possibly omitting proper indenting), note that this situation is avoidable by taking care of isinstance and issubclassof functions to make sure that when you really need a duck, you don't get a bomb.

class Bomb:
    def __init__(self):
        ""

    def talk(self):
        self.explode()

    def explode(self):
        print "BOOM!, The bomb explodes."

class Duck:
    def __init__(self):
        ""
    def talk(self):
        print "I am a duck, I will not blow up if you ask me to talk."    

class Kid:
    kids_duck = None

    def __init__(self):
        print "Kid comes around a corner and asks you for money so he could buy a duck."

    def takeDuck(self, duck):
        self.kids_duck = duck
        print "The kid accepts the duck, and happily skips along"

    def doYourThing(self):
        print "The kid tries to get the duck to talk"
        self.kids_duck.talk()

myKid = Kid()
myBomb = Bomb()
myKid.takeDuck(myBomb)
myKid.doYourThing()

Try to use this code to handle server disconnect:

var db_config = {
  host: 'localhost',
    user: 'root',
    password: '',
    database: 'example'
};

var connection;

function handleDisconnect() {
  connection = mysql.createConnection(db_config); // Recreate the connection, since
                                                  // the old one cannot be reused.

  connection.connect(function(err) {              // The server is either down
    if(err) {                                     // or restarting (takes a while sometimes).
      console.log('error when connecting to db:', err);
      setTimeout(handleDisconnect, 2000); // We introduce a delay before attempting to reconnect,
    }                                     // to avoid a hot loop, and to allow our node script to
  });                                     // process asynchronous requests in the meantime.
                                          // If you're also serving http, display a 503 error.
  connection.on('error', function(err) {
    console.log('db error', err);
    if(err.code === 'PROTOCOL_CONNECTION_LOST') { // Connection to the MySQL server is usually
      handleDisconnect();                         // lost due to either server restart, or a
    } else {                                      // connnection idle timeout (the wait_timeout
      throw err;                                  // server variable configures this)
    }

handleDisconnect();

In your code i am missing the parts after connection = mysql.createConnection(db_config);

This function:

• "Proper Cases" all "UPPER CASE" words that are delimited by white space
• leaves "lower case words" alone
• works properly even for non-English alphabets
• is portable in that it does not use fancy features of recent SQL server versions
• can be easily changed to use NCHAR and NVARCHAR for unicode support,as well as any parameter length you see fit
• white space definition can be configured

CREATE FUNCTION ToProperCase(@string VARCHAR(255)) RETURNS VARCHAR(255)
AS
BEGIN
  DECLARE @i INT           -- index
  DECLARE @l INT           -- input length
  DECLARE @c NCHAR(1)      -- current char
  DECLARE @f INT           -- first letter flag (1/0)

If you want to selected value on drop-down text bases so you should use below changes: Here below is example and country name is dynamic:

    <select id="selectcountry">
    <option value="1">India</option>
    <option value="2">Ireland</option>
    </select>
    <script>
     var country_name ='India'
     $('#selectcountry').find('option:contains("' + country_name + '")').attr('selected', 'selected');
    </script>

Here's what worked for me with a similar list of strings in Notepad++ without any macros or anything else:

1. Click Edit -> Blank Operations -> EOL to space [All the items should now be in a single line separated by a 'space']

2. Select any 'space' and do a Replace All (by ',')

I had similar issue where i had to save the contents of the dataframe to a csv file of name which i defined. df.write("csv").save("<my-path>") was creating directory than file. So have to come up with the following solutions. Most of the code is taken from the following dataframe-to-csv with little modifications to the logic.

def saveDfToCsv(df: DataFrame, tsvOutput: String, sep: String = ",", header: Boolean = false): Unit = {
    val tmpParquetDir = "Posts.tmp.parquet"

    df.repartition(1).write.
        format("com.databricks.spark.csv").
        option("header", header.toString).
        option("delimiter", sep).
        save(tmpParquetDir)

    val dir = new File(tmpParquetDir)
    val newFileRgex = tmpParquetDir + File.separatorChar + ".part-00000.*.csv"
    val tmpTsfFile = dir.listFiles.filter(_.toPath.toString.matches(newFileRgex))(0).toString
    (new File(tmpTsvFile)).renameTo(new File(tsvOutput))

    dir.listFiles.foreach( f => f.delete )
    dir.delete
    }

Scanner scanner = new Scanner(System.in);
int employeeId, supervisorId;
String name;
System.out.println("Enter employee ID:");
employeeId = scanner.nextInt();
scanner.nextLine(); //This is needed to pick up the new line
System.out.println("Enter employee name:");
name = scanner.nextLine();
System.out.println("Enter supervisor ID:");
supervisorId = scanner.nextInt();

Calling nextInt() was a problem as it didn't pick up the new line (when you hit enter). So, calling scanner.nextLine() after that does the work.

Using KeyGenerator would be the preferred method. As Duncan indicated, I would certainly give the key size during initialization. KeyFactory is a method that should be used for pre-existing keys.

OK, so lets get to the nitty-gritty of this. In principle AES keys can have any value. There are no "weak keys" as in (3)DES. Nor are there any bits that have a specific meaning as in (3)DES parity bits. So generating a key can be as simple as generating a byte array with random values, and creating a SecretKeySpec around it.

But there are still advantages to the method you are using: the KeyGenerator is specifically created to generate keys. This means that the code may be optimized for this generation. This could have efficiency and security benefits. It might be programmed to avoid a timing side channel attacks that would expose the key, for instance. Note that it may already be a good idea to clear any byte[] that hold key information as they may be leaked into a swap file (this may be the case anyway though).

Furthermore, as said, not all algorithms are using fully random keys. So using KeyGenerator would make it easier to switch to other algorithms. More modern ciphers will only accept fully random keys though; this is seen as a major benefit over e.g. DES.

Finally, and in my case the most important reason, it that the KeyGenerator method is the only valid way of handling AES keys within a secure token (smart card, TPM, USB token or HSM). If you create the byte[] with the SecretKeySpec then the key must come from memory. That means that the key may be put in the secure token, but that the key is exposed in memory regardless. Normally, secure tokens only work with keys that are either generated in the secure token or are injected by e.g. a smart card or a key ceremony. A KeyGenerator can be supplied with a provider so that the key is directly generated within the secure token.

As indicated in Duncan's answer: always specify the key size (and any other parameters) explicitly. Do not rely on provider defaults as this will make it unclear what your application is doing, and each provider may have its own defaults.

While you have specified the start anchor and the first letter, you have not done anything for the rest of the string. You seem to want repetition of that character class until the end of the string:

var regexp = /^\S*$/; // a string consisting only of non-whitespaces

Despite the imprecise nature of the question, here's my interpretive answer.

var html = [
    '<div> A line</div>',
    '<div> Add more lines</div>',
    '<div> To the array as you need.</div>'
].join('');

var div = document.createElement('div');
    div.setAttribute('class', 'post block bc2');
    div.innerHTML = html;
    document.getElementById('posts').appendChild(div);

In Swift 3

let data = string.data(using: .utf8)

In Swift 2 (or if you already have a NSString instance)

let data = string.dataUsingEncoding(NSUTF8StringEncoding)

In Swift 1 (or if you have a swift String):

let data = (string as NSString).dataUsingEncoding(NSUTF8StringEncoding)

Also note that data is an Optional<NSData> (since the conversion might fail), so you'll need to unwrap it before using it, for instance:

if let d = data {
    println(d)
}

If I had to guess, I'd say that you're from a Java background. This is C++, and things are passed by value unless you specify otherwise using the &-operator (note that this operator is also used as the 'address-of' operator, but in a different context). This is all well documented, but I'll re-iterate anyway:

void foo(vector<int> bar); // by value
void foo(vector<int> &bar); // by reference (non-const, so modifiable inside foo)
void foo(vector<int> const &bar); // by const-reference

You can also choose to pass a pointer to a vector (void foo(vector<int> *bar)), but unless you know what you're doing and you feel that this is really is the way to go, don't do this.

Also, vectors are not the same as arrays! Internally, the vector keeps track of an array of which it handles the memory management for you, but so do many other STL containers. You can't pass a vector to a function expecting a pointer or array or vice versa (you can get access to (pointer to) the underlying array and use this though). Vectors are classes offering a lot of functionality through its member-functions, whereas pointers and arrays are built-in types. Also, vectors are dynamically allocated (which means that the size may be determined and changed at runtime) whereas the C-style arrays are statically allocated (its size is constant and must be known at compile-time), limiting their use.

I suggest you read some more about C++ in general (specifically array decay), and then have a look at the following program which illustrates the difference between arrays and pointers:

void foo1(int *arr) { cout << sizeof(arr) << '\n'; }
void foo2(int arr[]) { cout << sizeof(arr) << '\n'; }
void foo3(int arr[10]) { cout << sizeof(arr) << '\n'; }
void foo4(int (&arr)[10]) { cout << sizeof(arr) << '\n'; }

int main()
{
    int arr[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
    foo1(arr);
    foo2(arr);
    foo3(arr);
    foo4(arr);
}

This worked for me: (notice that java 8 is required)

String requestData = request.getReader().lines().collect(Collectors.joining());
UserJsonParser u = gson.fromJson(requestData, UserJsonParser.class);

UserJsonParse is a class that shows gson how to parse the json formant.

class is like that:

public class UserJsonParser {

    private String username;
    private String name;
    private String lastname;
    private String mail;
    private String pass1;
//then put setters and getters
}

the json string that is parsed is like that:

$jsonData: {    "username": "testuser",    "pass1": "clave1234" }

The rest of values (mail, lastname, name) are set to null

to show path of selected file you can try this on html :

<div class="fileinputs">
    <input type="file" class="file">
</div>

and in javascript :

        var fakeFileUpload = document.createElement('div');
        fakeFileUpload.className = 'fakefile';
        var image = document.createElement('div');
        image.className='fakebtn';
        image.innerHTML = 'browse';
        fakeFileUpload.appendChild(image);
        fakeFileUpload.appendChild(document.createElement('input'));
        var x = document.getElementsByTagName('input');
        for (var i=0;i<x.length;i++) {
            if (x[i].type != 'file') continue;
            if (x[i].parentNode.className != 'fileinputs') continue;
            x[i].className = 'file hidden';
            var clone = fakeFileUpload.cloneNode(true);
            x[i].parentNode.appendChild(clone);
            x[i].relatedElement = clone.getElementsByTagName('input')[0];
            x[i].onchange = x[i].onmouseout = function () {
                this.relatedElement.value = this.value;
            }
        }

and style :

    height: 30px;
    width: 370px;

Here's some code taken from Kirk Evans Blog that demonstrates how to encode an image in C#;

//Load the picture from a file
Image picture = Image.FromFile(@"c:\temp\test.gif");

//Create an in-memory stream to hold the picture's bytes
System.IO.MemoryStream pictureAsStream = new System.IO.MemoryStream();
picture.Save(pictureAsStream, System.Drawing.Imaging.ImageFormat.Gif);

//Rewind the stream back to the beginning
pictureAsStream.Position = 0;
//Get the stream as an array of bytes
byte[] pictureAsBytes = pictureAsStream.ToArray();

//Create an XmlTextWriter to write the XML somewhere... here, I just chose
//to stream out to the Console output stream
System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(Console.Out);

//Write the root element of the XML document and the base64 encoded data
writer.WriteStartElement("w", "binData",
                         "http://schemas.microsoft.com/office/word/2003/wordml");

writer.WriteBase64(pictureAsBytes, 0, pictureAsBytes.Length);

writer.WriteEndElement();
writer.Flush();

Starting with a context, the root view of the associated activity can be had by

View rootView = ((Activity)_context).Window.DecorView.FindViewById(Android.Resource.Id.Content);

In Raw Android it'd look something like:

View rootView = ((Activity)mContext).getWindow().getDecorView().findViewById(android.R.id.content)

Then simply call the findViewById on this

View v = rootView.findViewById(R.id.your_view_id);

This is not possible.

Instead, you should create a fake window in Javascript, using something like jQuery UI Dialog.

In Notepad++ :

<option value value='1' >A
<option value value='2' >B
<option value value='3' >C
<option value value='4' >D


Find what: (.*)(>)(.)
Replace with: \3

Replace All


A
B
C
D

You're using S_ISREG() and S_ISDIR() correctly, you're just using them on the wrong thing.

In your while((dit = readdir(dip)) != NULL) loop in main, you're calling stat on currentPath over and over again without changing currentPath:

if(stat(currentPath, &statbuf) == -1) {
    perror("stat");
    return errno;
}

Shouldn't you be appending a slash and dit->d_name to currentPath to get the full path to the file that you want to stat? Methinks that similar changes to your other stat calls are also needed.

The pure javascript solution is better, but a jQuery way would be to use the jQuery grep and/or map methods. Probably not much better than using $.each

jQuery.grep(TestObj, function(obj) {
    return obj.id === "A";
});

or

jQuery.map(TestObj, function(obj) {
    if(obj.id === "A")
         return obj; // or return obj.name, whatever.
});

Returns an array of the matching objects, or of the looked-up values in the case of map. Might be able to do what you want simply using those.

But in this example you'd have to do some recursion, because the data isn't a flat array, and we're accepting arbitrary structures, keys, and values, just like the pure javascript solutions do.

function getObjects(obj, key, val) {
    var retv = [];

    if(jQuery.isPlainObject(obj))
    {
        if(obj[key] === val) // may want to add obj.hasOwnProperty(key) here.
            retv.push(obj);

        var objects = jQuery.grep(obj, function(elem) {
            return (jQuery.isArray(elem) || jQuery.isPlainObject(elem));
        });

        retv.concat(jQuery.map(objects, function(elem){
            return getObjects(elem, key, val);
        }));
    }

    return retv;
}

Essentially the same as Box9's answer, but using the jQuery utility functions where useful.

For the others, also check your stored procedure. In my case in my stored procedure CustomSearch I accidentally declared not enough length for my column, so when I entered a big data I received that error even though I have a big length on my database. I just changed the length of my column in my custom search the error goes away. This is just for the reminder. Thanks.

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

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

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

The output of the query is resulted as :

+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+

The lock accessed is on the object, not on the method. Which variables are accessed within the method is irrelevant.

Adding "synchronized" to the method means the thread running the code must acquire the lock on the object before proceeding. Adding "static synchronized" means the thread running the code must acquire the lock on the class object before proceeding. Alternatively you can wrap code in a block like this:

public void addA() {
    synchronized(this) {
        a++;
    }
}

so that you can specify the object whose lock must be acquired.

If you want to avoid locking on the containing object you can choose between:

• using synchronized blocks that specify different locks
• making a and b atomic (using java.util.concurrent.atomic)

import nltk is Python syntax, and as such won't work in a shell script.

To test the version of nltk and scikit_learn, you can write a Python script and run it. Such a script may look like

import nltk
import sklearn

print('The nltk version is {}.'.format(nltk.__version__))
print('The scikit-learn version is {}.'.format(sklearn.__version__))

# The nltk version is 3.0.0.
# The scikit-learn version is 0.15.2.

Note that not all Python packages are guaranteed to have a __version__ attribute, so for some others it may fail, but for nltk and scikit-learn at least it will work.

I believe best practice these days is H/5 * * * *, which means every 5 minutes with a hashing factor to avoid all jobs starting at EXACTLY the same time.

I am running Anaconda version 4.3.22 and a python3.6.1 environment, and had this problem. Here's the history and the fix:

pip uninstall opencv-python # -- the original step. failed.

ImportError: DLL load failed: The specified module could not be found.

I did this into my python3.6 environment and got this error.

python -m pip install opencv-python # same package as above.
conda install -c conda-forge opencv # separate install parallel to opencv
pip-install opencv-contrib-python # suggested by another user here. doesn't resolve it.

Next, I tried downloading python3.6 and putting the python3.dll in the folder and in various folders. nothing changed.

finally, this fixed it:

pip uninstall opencv-python

(the other conda-forge version is still installed) This left only the conda version, and that works in 3.6.

There is no portable way to read raw characters from a Java console.

Some platform-dependent workarounds have been presented above. But to be really portable, you'd have to abandon console mode and use a windowing mode, e.g. AWT or Swing.

I've seen many commercial applications, using the "DoEvents-Hack". Especially when rendering comes into play, I often see this:

while(running)
{
    Render();
    Application.DoEvents();
}

They all know about the evil of that method. However, they use the hack, because they don't know any other solution. Here are some approaches taken from a blog post by Tom Miller:

• Set your form to have all drawing occur in WmPaint, and do your rendering there. Before the end of the OnPaint method, make sure you do a this.Invalidate(); This will cause the OnPaint method to be fired again immediately.
• P/Invoke into the Win32 API and call PeekMessage/TranslateMessage/DispatchMessage. (Doevents actually does something similar, but you can do this without the extra allocations).
• Write your own forms class that is a small wrapper around CreateWindowEx, and give yourself complete control over the message loop. -Decide that the DoEvents method works fine for you and stick with it.

Try this

$("#globalsearchstr").focus(function(){
    $(this).parent().css("background", "url('../images/r-srchbg_white.png') no-repeat");
});

The VCS files can have its information coded in Quoted printable which is a nightmare. The above solution recommending "VCS to ICS Calendar Converter" is the way to go.

I just tried it, commenting super(); does the same thing without commenting it as @Mark Peters said

package javaapplication6;

/**

 */
public class Super_Test {
    Super_Test(){
        System.out.println("This is super class, no object is created");
    }
}
class Super_sub extends Super_Test{
    Super_sub(){
       super();
       System.out.println("This is sub class, object is created");
    }
    public static void main(String args[]){
        new Super_sub();
    }
}

In VBA (and VB.NET) the line terminator (carriage return) is used to signal the end of a statement. To break long statements into several lines, you need to

Use the line-continuation character, which is an underscore (_), at the point at which you want the line to break. The underscore must be immediately preceded by a space and immediately followed by a line terminator (carriage return).

(From How to: Break and Combine Statements in Code)

In other words: Whenever the interpreter encounters the sequence <space>_<line terminator>, it is ignored and parsing continues on the next line. Note, that even when ignored, the line continuation still acts as a token separator, so it cannot be used in the middle of a variable name, for example. You also cannot continue a comment by using a line-continuation character.

To break the statement in your question into several lines you could do the following:

U_matrix(i, j, n + 1) = _
     k * b_xyt(xi, yi, tn) / (4 * hx * hy) * U_matrix(i + 1, j + 1, n) + _
     (k * (a_xyt(xi, yi, tn) / hx ^ 2 + d_xyt(xi, yi, tn) / (2 * hx)))

(Leading whitespaces are ignored.)

To check if a grammar is LL(1), one option is to construct the LL(1) parsing table and check for any conflicts. These conflicts can be

• FIRST/FIRST conflicts, where two different productions would have to be predicted for a nonterminal/terminal pair.
• FIRST/FOLLOW conflicts, where two different productions are predicted, one representing that some production should be taken and expands out to a nonzero number of symbols, and one representing that a production should be used indicating that some nonterminal should be ultimately expanded out to the empty string.
• FOLLOW/FOLLOW conflicts, where two productions indicating that a nonterminal should ultimately be expanded to the empty string conflict with one another.

Let's try this on your grammar by building the FIRST and FOLLOW sets for each of the nonterminals. Here, we get that

FIRST(X) = {a, b, z}
FIRST(Y) = {b, epsilon}
FIRST(Z) = {epsilon} 

We also have that the FOLLOW sets are

FOLLOW(X) = {$}
FOLLOW(Y) = {z}
FOLLOW(Z) = {z}

From this, we can build the following LL(1) parsing table:

    a    b    z   $
X   a    Yz   Yz  
Y        bZ   eps
Z             eps

Since we can build this parsing table with no conflicts, the grammar is LL(1).

To check if a grammar is LR(0) or SLR(1), we begin by building up all of the LR(0) configurating sets for the grammar. In this case, assuming that X is your start symbol, we get the following:

(1)
X' -> .X
X -> .Yz
X -> .a
Y -> .
Y -> .bZ

(2)
X' -> X.

(3)
X -> Y.z

(4)
X -> Yz.

(5)
X -> a.

(6)
Y -> b.Z
Z -> .

(7)
Y -> bZ.

From this, we can see that the grammar is not LR(0) because there are shift/reduce conflicts in states (1) and (6). Specifically, because we have the reduce items Z → . and Y → ., we can't tell whether to reduce the empty string to these symbols or to shift some other symbol. More generally, no grammar with ε-productions is LR(0).

However, this grammar might be SLR(1). To see this, we augment each reduction with the lookahead set for the particular nonterminals. This gives back this set of SLR(1) configurating sets:

(1)
X' -> .X
X -> .Yz [$]
X -> .a  [$]
Y -> .   [z]
Y -> .bZ [z]

(2)
X' -> X.

(3)
X -> Y.z [$]

(4)
X -> Yz. [$]

(5)
X -> a.  [$]

(6)
Y -> b.Z [z]
Z -> .   [z]

(7)
Y -> bZ. [z]

Now, we don't have any more shift-reduce conflicts. The conflict in state (1) has been eliminated because we only reduce when the lookahead is z, which doesn't conflict with any of the other items. Similarly, the conflict in (6) is gone for the same reason.

Hope this helps!

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

You can try this all of method in our html page..

1st way

body { overflow-x:hidden; }

2nd way You can use the following in your CSS body tag:

overflow-y: scroll; overflow-x: hidden;

That will remove your scrollbar.

3rd way

body { min-width: 1167px; }

5th way

html, body { max-width: 100%; overflow-x: hidden; }

6th way

element { max-width: 100vw; overflow-x: hidden; }

4th way..

var docWidth = document.documentElement.offsetWidth; [].forEach.call( document.querySelectorAll('*'), function(el) { if (el.offsetWidth > docWidth) { console.log(el); } } );

Now i m searching about more..!!!!

You could do:
sh scriptname.sh

Basically the scope of workspace(s) is divided in two points.

First point (and primary) is the eclipse it self and is related with the settings and metadata configurations (plugin ctr). Each time you create a project, eclipse collects all the configurations and stores them on that workspace and if somehow in the same workspace a conflicting project is present you might loose some functionality or even stability of eclipse it self.

And second (secondary) the point of development strategy one can adopt. Once the primary scope is met (and mastered) and there's need for further adjustments regarding project relations (as libraries, perspectives ctr) then initiate separate workspace(s) could be appropriate based on development habits or possible language/frameworks "behaviors". DLTK for examples is a beast that should be contained in a separate cage. Lots of complains at forums for it stopped working (properly or not at all) and suggested solution was to clean the settings of the equivalent plugin from the current workspace.

Personally, I found myself lean more to language distinction when it comes to separate workspaces which is relevant to known issues that comes with the current state of the plugins are used. Preferably I keep them in the minimum numbers as this is leads to less frustration when the projects are become... plenty and version control is not the only version you keep your projects. Finally, loading speed and performance is an issue that might come up if lots of (unnecessary) plugins are loaded due to presents of irrelevant projects. Bottom line; there is no one solution to every one, no master blue print that solves the issue. It's something that grows with experience, Less is more though!

just delete the .svn folders, then run a cleanup on the parent directory. Works perfectly!!

var lst = new List<int>() { 1, 2, 3 };
var ans = lst.Where( i => i > 3 );

(ans == null).Dump();  // False
(ans.Count() == 0 ).Dump();  // True

(Dump is from LinqPad)

Specifying tests / selecting tests

Pytest supports several ways to run and select tests from the command-line.

Run tests in a module

pytest test_mod.py

Run tests in a directory

pytest testing/

Run tests by keyword expressions

pytest -k "MyClass and not method"

This will run tests which contain names that match the given string expression, which can include Python operators that use filenames, class names and function names as variables. The example above will run TestMyClass.test_something but not TestMyClass.test_method_simple.

Run tests by node ids

Each collected test is assigned a unique nodeid which consist of the module filename followed by specifiers like class names, function names and parameters from parametrization, separated by :: characters.

To run a specific test within a module:

pytest test_mod.py::test_func

Another example specifying a test method in the command line:

pytest test_mod.py::TestClass::test_method

Run tests by marker expressions

pytest -m slow

Will run all tests which are decorated with the @pytest.mark.slow decorator.

For more information see marks.

Run tests from packages

pytest --pyargs pkg.testing

This will import pkg.testing and use its filesystem location to find and run tests from.

You have at least two issues in your code:

• ng-change="getScoreData(Score)

  Angular doesn't see getScoreData method that refers to defined service

• getScoreData: function (Score, callback)

  We don't need to use callback since GET returns promise. Use then instead.

Here is a working example (I used random address only for simulation):

HTML

<select ng-model="score"
        ng-change="getScoreData(score)" 
        ng-options="score as score.name for score in  scores"></select>
    <pre>{{ScoreData|json}}</pre> 

JS

var fessmodule = angular.module('myModule', ['ngResource']);

fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {

    $scope.scores = [{
        name: 'Bukit Batok Street 1',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
    }, {
        name: 'London 8',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
    }];

    $scope.getScoreData = function(score) {
        ScoreDataService.getScoreData(score).then(function(result) {
            $scope.ScoreData = result;
        }, function(result) {
            alert("Error: No data returned");
        });
    };

});

fessmodule.$inject = ['$scope', 'ScoreDataService'];

fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {

    var factory = {
        getScoreData: function(score) {
            console.log(score);
            var data = $http({
                method: 'GET',
                url: score.URL
            });


            return data;
        }
    }
    return factory;
}]);

Demo Fiddle

private static void appendZeroAtStart() {
        String strObj = "11";
        int maxLegth = 5;

        StringBuilder sb = new StringBuilder(strObj);

Documenting another source of errors for installing gcc-10 on Amazon Linux 2 from source.

After running sudo make install and then testing gcc-10 I got this error:

gcc-10: fatal error: cannot execute ‘cc1’: execvp: No such file or directory

The reason was that the new g++ directories under /usr/local/ were created by sudo make install have 700 permissions so non-root users cannot see the directories content.

I fixed it by running

sudo find /usr/local/ -type d -exec chmod 755 {} \;

Note that I followed this snippet https://gist.github.com/nchaigne/ad06bc867f911a3c0d32939f1e930a11

My understanding of margin and padding comes from google's developer tool in the image attached

In Simple words, a margin is the space around an element and padding means the space between an element and the content inside that element. Both these two are used to create gaps but in different ways.

Using Margin to create gap:

In creating gap margin pushes the adjacent elements away

Using Padding to create gap:

Using padding to create gap either grows the element's size or shrinks the content inside

Why is it important to know the difference?

It is important to know the difference so you could know when to use either of them and use them appropriately.

It is also worthy of note that margins and padding come handy when designing a website's layout, as margin specifies whether an element will move up or down, left or right while padding specifies how an element will look and sit inside its container.

This might work for you (GNU sed):

sed -ri  '/\s+$/s///' file

This looks for whitespace at the end of the line and and if present removes it.

For array type Please try this one.

 List<MyStok> myDeserializedObjList = (List<MyStok>)Newtonsoft.Json.JsonConvert.DeserializeObject(sc), typeof(List<MyStok>));

Please See here for details to deserialise Json

In my case, we have time series from different devices but some devices could not send any value during some period. So we should create NA values for every device and time period and after that do fillna.

df = pd.DataFrame([["device1", 1, 'first val of device1'], ["device2", 2, 'first val of device2'], ["device3", 3, 'first val of device3']])
df.pivot(index=1, columns=0, values=2).fillna(method='ffill').unstack().reset_index(name='value')

Result:

        0   1   value
0   device1     1   first val of device1
1   device1     2   first val of device1
2   device1     3   first val of device1
3   device2     1   None
4   device2     2   first val of device2
5   device2     3   first val of device2
6   device3     1   None
7   device3     2   None
8   device3     3   first val of device3

And in case you come here, like I did, looking to do the same thing for plots in a Julia notebook in Jupyter, using Plots, you can use:

    IJulia.clear_output(true)

so for a kind of animated plot of multiple runs

    if nrun==1  
      display(plot(x,y))         # first plot
    else 
      IJulia.clear_output(true)  # clear the window (as above)
      display(plot!(x,y))        # plot! overlays the plot
    end

Without the clear_output call, all plots appear separately.

I had the same error with JBoss 7.1.. And I did the same as Zefiro. Just ignored the error and i was able to place breakpoints normally. In my case i was building thought ant builder and this is my javac task:

Another way

@Html.TextAreaFor(model => model.Comments[0].Comment)

And in your css do this

textarea
{
    font-family: inherit;
    width: 650px;
    height: 65px;
}

That DataType dealie allows carriage returns in the data, not everybody likes those.

Double escaping is required when presented as a string.

Whenever I'm making a new regular expression I do a bunch of tests with online tools, for example: http://www.regexplanet.com/advanced/java/index.html

That website allows you to enter the regular expression, which it'll escape into a string for you, and you can then test it against different inputs.

The typical command is:

docker container ls -f 'status=exited'

However, this will only list one of the possible non-running statuses. Here's a list of all possible statuses:

• created
• restarting
• running
• removing
• paused
• exited
• dead

You can filter on multiple statuses by passing multiple filters on the status:

docker container ls -f 'status=exited' -f 'status=dead' -f 'status=created'

If you are integrating this with an automatic cleanup script, you can chain one command to another with some bash syntax, output just the container id's with -q, and you can also limit to just the containers that exited successfully with an exit code filter:

docker container rm $(docker container ls -q -f 'status=exited' -f 'exited=0')

For more details on filters you can use, see Docker's documentation: https://docs.docker.com/engine/reference/commandline/ps/#filtering

I think you are looking for the Dictionary object, found in the Microsoft Scripting Runtime library. (Add a reference to your project from the Tools...References menu in the VBE.)

It pretty much works with any simple value that can fit in a variant (Keys can't be arrays, and trying to make them objects doesn't make much sense. See comment from @Nile below.):

Dim d As dictionary
Set d = New dictionary

d("x") = 42
d(42) = "forty-two"
d(CVErr(xlErrValue)) = "Excel #VALUE!"
Set d(101) = New Collection

You can also use the VBA Collection object if your needs are simpler and you just want string keys.

I don't know if either actually hashes on anything, so you might want to dig further if you need hashtable-like performance. (EDIT: Scripting.Dictionary does use a hash table internally.)

What's a "block scheme"?

If I were drawing it, I might draw a box with "for each x in y" written in it.

If you're drawing a flowchart, there's always a loop with a decision box.

Nassi-Schneiderman diagrams have a loop construct you could use.

Another way so easy:

function outside:

function funx(functionEvents, params) {
  console.log("events of funx function: ", functionEvents);
  console.log("this of component: ", this);
  console.log("params: ", params);
  thisFunction.persist();
}

Bind it:

constructor(props) {
   super(props);
    this.state = {};
    this.funxBinded = funx.bind(this);
  }
}

Please see complete tutorial here: How to use "this" of a React Component from outside?

You can use the sibling selector ~:

h1.hc-reform ~ p{
     clear:both;
}

This selects all the p elements that come after .hc-reform, not just the first one.

Want to format it automatically when you save the file???

then Goto Window > Preferences > Java > Editor > Save Actions

and configure your save actions.

Along with saving, you can format, Organize imports,add modifier ‘final’ where possible etc

It means, the Class reference type can hold any Class object which represents any type. If JVM loads a type, a class object representing that type will be present in JVM. we can get the metadata regarding the type from that class object which is used very much in reflection package.

Suppose you have a a class named "myPackage.MyClass". Assuming that is in classpath, the following statements are equivalent.

Class<?> myClassObject = MyClass.class; //compile time check

Class<?> myClassObject = Class.forname("myPackage.MyClass"); //only runtime check

This works in a similar fashion if the Class<?> reference is in method argument as well.

Please note that the class "Class" does not have a public constructor. So you cannot instantiate "Class" instances with "new" operator.

In case you want to tag a specific commit like i do

Here's a command to do that :-

Example:

git tag -a v1.0 7cceb02 -m "Your message here"

Where 7cceb02 is the beginning part of the commit id.

You can then push the tag using git push origin v1.0.

You can do git log to show all the commit id's in your current branch.

In case of float values with characters 'e' '+' it errors out if we try to convert in decimal. ('2.81104e+006'). It still pass ISNUMERIC test.

SELECT ISNUMERIC('2.81104e+006') 

returns 1.

SELECT convert(decimal(15,2), '2.81104e+006') 

returns

error: Error converting data type varchar to numeric.

And

SELECT try_convert(decimal(15,2), '2.81104e+006') 

returns NULL.

SELECT convert(float, '2.81104e+006') 

returns the correct value 2811040.

This is how Adding new column to Table

ALTER TABLE [tableName]
ADD ColumnName Datatype

E.g

ALTER TABLE [Emp]
ADD Sr_No Int

And If you want to make it auto incremented

ALTER TABLE [Emp]
ADD Sr_No Int IDENTITY(1,1) NOT NULL

</LinearLayout>

Note the "highlighted" View, I didn't modify anything else. Height=0 makes sure it's not visible. Width=0 is because the width is determined by the LinearLayout based on weight=1. This means that the spacer view will stretch as much as possible in the direction (orientation) of the LinearLayout.

Note that you should use android.widget.Space or android.support.v4.widget.Space instead of View if your API level and/or dependencies allow it. Space achieves the job in a cheaper way, because it only measures and doesn't try to draw anything like View does; it's also more expressive conveying the intention.

A slight improvement on kasku's and Pini's answers, which plays nicer with spaces and allows passing relative paths:

#!/bin/bash
# both $1 and $2 are paths
# returns $2 relative to $1
absolute=`readlink -f "$2"`
current=`readlink -f "$1"`
# Perl is magic
# Quoting horror.... spaces cause problems, that's why we need the extra " in here:
relative=$(perl -MFile::Spec -e "print File::Spec->abs2rel(q($absolute),q($current))")

echo $relative

Updated 2018

Make sure your table includes the table class. This is because Bootstrap 4 tables are "opt-in" so the table class must be intentionally added to the table.

http://codeply.com/go/zJLXypKZxL

Bootstrap 3.x also had some CSS to reset the table cells so that they don't float..

table td[class*=col-], table th[class*=col-] {
    position: static;
    display: table-cell;
    float: none;
}

I don't know why this isn't is Bootstrap 4 alpha, but it may be added back in the final release. Adding this CSS will help all columns to use the widths set in the thead..

Bootstrap 4 Alpha 2 Demo

UPDATE (as of Bootstrap 4.0.0)

Now that Bootstrap 4 is flexbox, the table cells will not assume the correct width when adding col-*. A workaround is to use the d-inline-block class on the table cells to prevent the default display:flex of columns.

Another option in BS4 is to use the sizing utils classes for width...

<thead>
     <tr>
           <th class="w-25">25</th>
           <th class="w-50">50</th>
           <th class="w-25">25</th>
     </tr>
</thead>

Bootstrap 4 Alpha 6 Demo

Lastly, you could use d-flex on the table rows (tr), and the col-* grid classes on the columns (th,td)...

<table class="table table-bordered">
        <thead>
            <tr class="d-flex">
                <th class="col-3">25%</th>
                <th class="col-3">25%</th>
                <th class="col-6">50%</th>
            </tr>
        </thead>
        <tbody>
            <tr class="d-flex">
                <td class="col-sm-3">..</td>
                <td class="col-sm-3">..</td>
                <td class="col-sm-6">..</td>
            </tr>
        </tbody>
    </table>

Bootstrap 4.0.0 (stable) Demo

Note: Changing the TR to display:flex can alter the borders

You can use dotPeek The only thing I have to say is that when using it, right-click on the class to select Decompiled Source instead of double-clicking, otherwise dotpeek will only display the contents of the local cs file, not the decompiled content. Option instance

to do it we have to know the three components

1. the place responsible for firing the Event
2. the place responsible for responding to the Event

3. the Event itself

   a. Event

   b .EventArgs

   c. EventArgs enumeration

now lets create Event that fired when a function is called

but I my order of solving this problem like this: I'm using the class before I create it

1. the place responsible for responding to the Event

   NetLog.OnMessageFired += delegate(object o, MessageEventArgs args) 
   {
           // when the Event Happened I want to Update the UI
           // this is WPF Window (WPF Project)  
           this.Dispatcher.Invoke(() =>
           {
               LabelFileName.Content = args.ItemUri;
               LabelOperation.Content = args.Operation;
               LabelStatus.Content = args.Status;
           });
   };
   

NetLog is a static class I will Explain it later

the next step is

2. the place responsible for firing the Event

   //this is the sender object, MessageEventArgs Is a class I want to create it  and Operation and Status are Event enums
   NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Started));
   downloadFile = service.DownloadFile(item.Uri);
   NetLog.FireMessage(this, new MessageEventArgs("File1.txt", Operation.Download, Status.Finished));
   

the third step

3. the Event itself

I warped The Event within a class called NetLog

public sealed class NetLog
{
    public delegate void MessageEventHandler(object sender, MessageEventArgs args);

    public static event MessageEventHandler OnMessageFired;
    public static void FireMessage(Object obj,MessageEventArgs eventArgs)
    {
        if (OnMessageFired != null)
        {
            OnMessageFired(obj, eventArgs);
        }
    }
}

public class MessageEventArgs : EventArgs
{
    public string ItemUri { get; private set; }
    public Operation Operation { get; private set; }
    public Status Status { get; private set; }

    public MessageEventArgs(string itemUri, Operation operation, Status status)
    {
        ItemUri = itemUri;
        Operation = operation;
        Status = status;
    }
}

public enum Operation
{
    Upload,Download
}

public enum Status
{
    Started,Finished
}

this class now contain the Event, EventArgs and EventArgs Enums and the function responsible for firing the event

sorry for this long answer

Use Apache CollectionUtils:

CollectionUtils.find(myList, new Predicate() {
   public boolean evaluate(Object o) {
      return name.equals(((MyClass) o).getName());
   }
}

Before datalist (see note below), you would supply an additional input element for people to type in their own option.

<select name="example">
  <option value="A">A</option>
  <option value="B">B</option>
  <option value="-">Other</option>
</select>

<input type="text" name="other">

This mechanism works in all browsers and requires no JavaScript.

You could use a little JavaScript to be clever about only showing the input if the "Other" option was selected.

datalist Element

The datalist element is intended to provide a better mechanism for this concept. In some browsers, e.g. iOS Safari < 12.2, this was not supported or the implementation had issues. Check the Can I Use page to see current datalist support.

<input type="text" name="example" list="exampleList">
<datalist id="exampleList">
  <option value="A">  
  <option value="B">
</datalist>

To force Finder to display hidden files and folders via Terminal:

    Open Terminal
    For OS X 10.9 Mavericks, run this command (lower-case finder):
    defaults write com.apple.finder AppleShowAllFiles TRUE
    For OS X 10.8 Mountain Lion, 10.7, or 10.6, run this command (upper-case Finder):
    defaults write com.apple.Finder AppleShowAllFiles true
    notice the setting for true
    Then run this command: killall Finder
    Then exit Terminal
    To revert back to Finder’s default setting (hide hidden files and folders), 
run the opposite command but with the false setting.

Then run killall Finder and exit Terminal.

To be thorough and remove lines even if they include spaces or tabs something like this in perl will do it:

cat file.txt | perl -lane "print if /\S/"

Of course there are the awk and sed equivalents. Best not to assume the lines are totally blank as ^$ would do.

After much searching for a solution to this very issue, this particular page seemed to have the most beef...however, nothing quite fit exactly, so I took the old-fashioned way and just parsed the stuff out I wanted out. Hope this helps someone. (Note: this also removes the SOAP or similar envelope stuff.)

        //

I resolved this by clearing App Data.

Cypress documentation admits that App Data can get corrupted:

Cypress maintains some local application data in order to save user preferences and more quickly start up. Sometimes this data can become corrupted. You may fix an issue you have by clearing this app data.

1. Open Cypress via cypress open
2. Go to File -> View App Data
3. This will take you to the directory in your file system where your App Data is stored. If you cannot open Cypress, search your file system for a directory named cy whose content should look something like this:

       production
            all.log
            browsers
            bundles
            cache
            projects
            proxy

I had the same problem, none of the solutions listed here worked. The problem was my source files where not inside the right folder.

The directory structure MUST be :

[project]\[module]\src\main\java\[yourpackage]\[yourclass.java]

No, it is not okay to put a link element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):

“This element defines a link. Unlike A, it may only appear in the HEAD section of a document, although it may appear any number of times.”

From the fine manual.

You must own the table to use ALTER TABLE.

Or be a database superuser.

ERROR: must be owner of relation contact

PostgreSQL error messages are usually spot on. This one is spot on.

I have a solution that involves (Vanilla) JavaScript, but only as a library. You habe to include it once and then all you need to do is set the appropriate source attribute of the number inputs.

The source attribute should be the querySelectorAll selector of the range input you want to listen to.

It even works with selectcs. And it works with multiple listeners. And it works in the other direction: change the number input and the range input will adjust. And it will work on elements added later onto the page (check https://codepen.io/HerrSerker/pen/JzaVQg for that)

There are two other solutions which involve assigning to an index one past the end of the list. Here is a solution that does use append.

resultsa <- list(1,2,3,4,5)
resultsb <- list(6,7,8,9,10)
resultsc <- list(11,12,13,14,15)

outlist <- list(resultsa)
outlist <- append(outlist, list(resultsb))
outlist <- append(outlist, list(resultsc))

which gives your requested format

> str(outlist)
List of 3
 $ :List of 5
  ..$ : num 1
  ..$ : num 2
  ..$ : num 3
  ..$ : num 4
  ..$ : num 5
 $ :List of 5
  ..$ : num 6
  ..$ : num 7
  ..$ : num 8
  ..$ : num 9
  ..$ : num 10
 $ :List of 5
  ..$ : num 11
  ..$ : num 12
  ..$ : num 13
  ..$ : num 14
  ..$ : num 15

It's simple

y = [['vegas','London'],['US','UK']]

for x in y:
    for a in x:
        print(a)

after looking for a similar solution and not finding anything flexible enough, I decided to write my own function for it. It allows you to have as many bars per group as you wish and specify both the width of a group as well as the individual widths of the bars within the groups.

Enjoy:

from matplotlib import pyplot as plt


def bar_plot(ax, data, colors=None, total_width=0.8, single_width=1, legend=True):
    """Draws a bar plot with multiple bars per data point.

    Parameters
    ----------
    ax : matplotlib.pyplot.axis
        The axis we want to draw our plot on.

    data: dictionary
        A dictionary containing the data we want to plot. Keys are the names of the
        data, the items is a list of the values.

        Example:
        data = {

            "y":[1,2,3],
            "z":[1,2,3],

    colors : array-like, optional
        A list of colors which are used for the bars. If None, the colors
        will be the standard matplotlib color cyle. (default: None)

    total_width : float, optional, default: 0.8
        The width of a bar group. 0.8 means that 80% of the x-axis is covered
        by bars and 20% will be spaces between the bars.

    single_width: float, optional, default: 1
        The relative width of a single bar within a group. 1 means the bars
        will touch eachother within a group, values less than 1 will make
        these bars thinner.

    legend: bool, optional, default: True

Output:

Marc's answer is of course the right answer. But since he mentioned the shift operators and unsafe code as an alternative. I would like to share a less common alternative. Using a struct with Explicit layout. This is similar in principal to a C/C++ union.

Here is an example of a struct that can be used to get to the component bytes of the Int32 data type and the nice thing is that it is two way, you can manipulate the byte values and see the effect on the Int.

  using System.Runtime.InteropServices;

  [StructLayout(LayoutKind.Explicit)]
  struct Int32Converter
  {
    [FieldOffset(0)] public int Value;
    [FieldOffset(0)] public byte Byte1;
    [FieldOffset(1)] public byte Byte2;
    [FieldOffset(2)] public byte Byte3;
    [FieldOffset(3)] public byte Byte4;

    public Int32Converter(int value)
    {
      Byte1 = Byte2 = Byte3 = Byte4 = 0;
      Value = value;
    }

    public static implicit operator Int32(Int32Converter value)
    {
      return value.Value;
    }

    public static implicit operator Int32Converter(int value)
    {
      return new Int32Converter(value);
    }
  }

The above can now be used as follows

 Int32Converter i32 = 256;
 Console.WriteLine(i32.Byte1);
 Console.WriteLine(i32.Byte2);
 Console.WriteLine(i32.Byte3);
 Console.WriteLine(i32.Byte4);

 i32.Byte2 = 2;
 Console.WriteLine(i32.Value);

Of course the immutability police may not be excited about the last possiblity :)

The direct replacement is if/elif/else.

However, in many cases there are better ways to do it in Python. See "Replacements for switch statement in Python?".

use this and it works on both the static arrays and dynamically generated arrays.

var array = [12,2,23,324,23,123,4,23,132,23];
var getMaxValue = Math.max.apply(Math, array );

I had the issue when I use trying to find max value from code below

$('#myTabs').find('li.active').prevAll().andSelf().each(function () {
            newGetWidthOfEachTab.push(parseInt($(this).outerWidth()));
        });

        for (var i = 0; i < newGetWidthOfEachTab.length; i++) {
            newWidthOfEachTabTotal += newGetWidthOfEachTab[i];
            newGetWidthOfEachTabArr.push(parseInt(newWidthOfEachTabTotal));
        }

        getMaxValue = Math.max.apply(Math, array);

I was getting 'NAN' when I use

    var max_value = Math.max(12, 21, 23, 2323, 23);

with my code

I'd suggest looking into fetch. It is the ES5 equivalent and uses Promises. It is much more readable and easily customizable.

const url = "https://stackoverflow.com";
fetch(url)
    .then(
        response => response.text() // .json(), etc.
        // same as function(response) {return response.text();}
    ).then(
        html => console.log(html)
    );

In Node.js, you'll need to import fetch using:

const fetch = require("node-fetch");

If you want to use it synchronously (doesn't work in top scope):

const json = await fetch(url)
  .then(response => response.json())
  .catch((e) => {});

The reason why your code is slow is that your LDAP query retrieves every single user object in your domain even though you're only interested in one user with a common name of "Adit":

dSearcher.Filter = "(&(objectClass=user))";

So to optimize, you need to narrow your LDAP query to just the user you are interested in. Try something like:

dSearcher.Filter = "(&(objectClass=user)(cn=Adit))";

In addition, don't forget to dispose these objects when done:

• DirectoryEntry dEntry
• DirectorySearcher dSearcher

color = lambda : [random.randint(0, 255), random.randint(0, 255), random.randint(0, 255)]

According to the Wordpress documentation, you should use wp_localize_script() in your functions.php file. This will create a Javascript Object in the header, which will be available to your scripts at runtime.

See Codex

Example:

<?php wp_localize_script('mylib', 'WPURLS', array( 'siteurl' => get_option('siteurl') )); ?>

To access this variable within in Javascript, you would simply do:

<script type="text/javascript">
    var url = WPURLS.siteurl;
</script>

In addition to return false as Jason Cohen mentioned. You may have to also preventDefault

e.preventDefault();

On windows, I have observed that this issue shows up if you do not have administrative rights (i.e., you are not a local administrator) on the machine.

As someone else suggested, the solution seems to be to install locally by not using the -g hint.

This was an old question, but existing answers ignore the serious issue of throwing away any custom attributes when you regenerate the model. I am adding a more detailed answer to cover the current options available.

You have 3 options:

• Add a [DisplayName("Name goes here")] attribute to the data model class. The downside is that this is thrown away whenever you regenerate the data models.
• Add a string parameter to your Html.LabelFor. e.g. @Html.LabelFor(model => model.SomekingStatus, "My New Label", new { @class = "control-label"}) Reference: https://msdn.microsoft.com/en-us/library/system.web.mvc.html.labelextensions.labelfor(v=vs.118).aspx The downside to this is that you must repeat the label in every view.
• Third option. Use a meta-data class attached to the data class (details follow).

Option 3 - Add a Meta-Data Class:

Microsoft allows for decorating properties on an Entity Framework class, without modifying the existing class! This by having meta-data classes that attach to your database classes (effectively a sideways extension of your EF class). This allow attributes to be added to the associated class and not to the class itself so the changes are not lost when you regenerate the data models.

For example, if your data class is MyModel with a SomekingStatus property, you could do it like this:

First declare a partial class of the same name (and using the same namespace), which allows you to add a class attribute without being overridden:

[MetadataType(typeof(MyModelMetaData))]
public partial class MyModel
{
}

All generated data model classes are partial classes, which allow you to add extra properties and methods by simply creating more classes of the same name (this is very handy and I often use it e.g. to provide formatted string versions of other field types in the model).

Step 2: add a metatadata class referenced by your new partial class:

public class MyModelMetaData
{
    // Apply DisplayNameAttribute (or any other attributes)
    [DisplayName("My New Label")]
    public string SomekingStatus;
}

Reference: https://msdn.microsoft.com/en-us/library/system.componentmodel.dataannotations.metadatatypeattribute(v=vs.110).aspx

Notes:

• From memory, if you start using a metadata class, it may ignore existing attributes on the actual class ([required] etc) so you may need to duplicate those in the Meta-data class.
• This does not operate by magic and will not just work with any classes. The code that looks for UI decoration attributes is designed to look for a meta-data class first.

Uncommenting the

always_populate_raw_post_data = -1 

in php.ini ( line# 703 ) and restarting APACHE services help me get rid from the message anyway

As of Python 3.2 unittest.TestCase.assertItemsEqual(doc) has been replaced by unittest.TestCase.assertCountEqual(doc) which does exactly what you are looking for, as you can read from the python standard library documentation. The method is somewhat misleadingly named but it does exactly what you are looking for.

a and b have the same elements in the same number, regardless of their order

Here a simple example which compares two lists having the same elements but in a different order.

• using assertCountEqual the test will succeed
• using assertListEqual the test will fail due to the order difference of the two lists

Here a little example script.

import unittest


class TestListElements(unittest.TestCase):
    def setUp(self):
        self.expected = ['foo', 'bar', 'baz']
        self.result = ['baz', 'foo', 'bar']

    def test_count_eq(self):
        """Will succeed"""
        self.assertCountEqual(self.result, self.expected)

    def test_list_eq(self):
        """Will fail"""
        self.assertListEqual(self.result, self.expected)

if __name__ == "__main__":
    unittest.main()

Side Note : Please make sure that the elements in the lists you are comparing are sortable.

Your operation did not fail.

Your backend service is saying that the response type it is returning is not provided in the Accept HTTP header in your Client request.

Ref: http://en.wikipedia.org/wiki/List_of_HTTP_header_fields

1. Find out the response (content type) returned by Service.
2. Provide this (content type) in your request Accept header.

If your array has a natural order use binary search.

Use binary search.

Binary search has O(log n) access time.

Here are the steps on how to use binary search,

• What is the ordering of you array? For example, is it sorted by name?
• Use bsearch to find elements or indices

Code example

# assume array is sorted by name!

array.bsearch { |each| "Jamie" <=> each.name } # returns element
(0..array.size).bsearch { |n| "Jamie" <=> array[n].name } # returns index

Yes since there are 2 distinct Global Assembly Cache (GAC), you will have to manage each of them individually.

In .NET Framework 4.0, the GAC went through a few changes. The GAC was split into two, one for each CLR.

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. There was no need in the previous two framework releases to split GAC. The problem of breaking older applications in Net Framework 4.0.

To avoid issues between CLR 2.0 and CLR 4.0 , the GAC is now split into private GAC’s for each runtime.The main change is that CLR v2.0 applications now cannot see CLR v4.0 assemblies in the GAC.

Source

Why?

It seems to be because there was a CLR change in .NET 4.0 but not in 2.0 to 3.5. The same thing happened with 1.1 to 2.0 CLR. It seems that the GAC has the ability to store different versions of assemblies as long as they are from the same CLR. They do not want to break old applications.

See the following information in MSDN about the GAC changes in 4.0.

For example, if both .NET 1.1 and .NET 2.0 shared the same GAC, then a .NET 1.1 application, loading an assembly from this shared GAC, could get .NET 2.0 assemblies, thereby breaking the .NET 1.1 application

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. As a result of this, there was no need in the previous two framework releases to split the GAC. The problem of breaking older (in this case, .NET 2.0) applications resurfaces in Net Framework 4.0 at which point CLR 4.0 released. Hence, to avoid interference issues between CLR 2.0 and CLR 4.0, the GAC is now split into private GACs for each runtime.

As the CLR is updated in future versions you can expect the same thing. If only the language changes then you can use the same GAC.

Note in 2018: readAsBinaryString is outdated. For use cases where previously you'd have used it, these days you'd use readAsArrayBuffer (or in some cases, readAsDataURL) instead.

readAsBinaryString says that the data must be represented as a binary string, where:

...every byte is represented by an integer in the range [0..255].

JavaScript originally didn't have a "binary" type (until ECMAScript 5's WebGL support of Typed Array* (details below) -- it has been superseded by ECMAScript 2015's ArrayBuffer) and so they went with a String with the guarantee that no character stored in the String would be outside the range 0..255. (They could have gone with an array of Numbers instead, but they didn't; perhaps large Strings are more memory-efficient than large arrays of Numbers, since Numbers are floating-point.)

If you're reading a file that's mostly text in a western script (mostly English, for instance), then that string is going to look a lot like text. If you read a file with Unicode characters in it, you should notice a difference, since JavaScript strings are UTF-16** (details below) and so some characters will have values above 255, whereas a "binary string" according to the File API spec wouldn't have any values above 255 (you'd have two individual "characters" for the two bytes of the Unicode code point).

If you're reading a file that's not text at all (an image, perhaps), you'll probably still get a very similar result between readAsText and readAsBinaryString, but with readAsBinaryString you know that there won't be any attempt to interpret multi-byte sequences as characters. You don't know that if you use readAsText, because readAsText will use an encoding determination to try to figure out what the file's encoding is and then map it to JavaScript's UTF-16 strings.

You can see the effect if you create a file and store it in something other than ASCII or UTF-8. (In Windows you can do this via Notepad; the "Save As" as an encoding drop-down with "Unicode" on it, by which looking at the data they seem to mean UTF-16; I'm sure Mac OS and *nix editors have a similar feature.)

If I use that with a "Testing 1 2 3" file stored in UTF-16, here are the results I get:

Text (13):

54 65 73 74 69 6e 67 20 31 20 32 20 33

Binary (28):

ff fe 54 00 65 00 73 00 74 00 69 00 6e 00 67 00 20 00 31 00 20 00 32 00 20 00 33 00

As you can see, readAsText interpreted the characters and so I got 13 (the length of "Testing 1 2 3"), and readAsBinaryString didn't, and so I got 28 (the two-byte BOM plus two bytes for each character).

* XMLHttpRequest.response with responseType = "arraybuffer" is supported in HTML 5.

** "JavaScript strings are UTF-16" may seem like an odd statement; aren't they just Unicode? No, a JavaScript string is a series of UTF-16 code units; you see surrogate pairs as two individual JavaScript "characters" even though, in fact, the surrogate pair as a whole is just one character. See the link for details.

afaik to make a request to information_schema you need privileges. If you need simple list of keys you can use this command:

SHOW INDEXES IN <tablename>

All have suggested big solution why you are worrying of session on client side. I mean when state/url changes I suppose you are doing an ajax call to load the data for tempelate.

Note :- To Save user's data you may use `resolve` feature of `ui-router`.
 Check cookie if it exist load template , if even cookies doesn't exist than 
there is no chance of logged in , simply redirect to login template/page.

Now the ajax data is returned by server using any api. Now the point came into play , return standard return types using server according to logged in status of user. Check those return codes and process your request in controller. Note:- For controller which doesn't require an ajax call natively , you can call a blank request to server like this server.location/api/checkSession.php and this is checkSession.php

<?php/ANY_LANGUAGE
session_start();//You may use your language specific function if required
if(isset($_SESSION["logged_in"])){
set_header("200 OK");//this is not right syntax , it is just to hint
}
else{
set_header("-1 NOT LOGGED_IN");//you may set any code but compare that same       
//code on client side to check if user is logged in or not.
}
//thanks.....

On client side inside controller or through any service as shown in other answers

    $http.get(dataUrl)
    .success(function (data){
        $scope.templateData = data;
    })
    .error(function (error, status){
        $scope.data.error = { message: error, status: status};
        console.log($scope.data.error.status);
if(status == CODE_CONFIGURED_ON_SERVER_SIDE_FOR_NON_LOGGED_IN){
//redirect to login
  });

Note :- I will update more tomorrow or in future

If you are calling from some fragment so do below code.

Intent intent = getActivity().getIntent();
getActivity().finish();
startActivity(intent);

An alternative is to call the pip module by using python2.7, as below:

python2.7 -m pip <commands>

For example, you could run python2.7 -m pip install <package> to install your favorite python modules. Here is a reference: https://stackoverflow.com/a/50017310/4256346.

In case the pip module has not yet been installed for this version of python, you can run the following:

python2.7 -m ensurepip

Running this command will "bootstrap the pip installer". Note that running this may require administrative privileges (i.e. sudo). Here is a reference: https://docs.python.org/2.7/library/ensurepip.html and another reference https://stackoverflow.com/a/46631019/4256346.

Example

Create and use a @Repeat annotation as follows:

public class MyTestClass {

    @Rule
    public RepeatRule repeatRule = new RepeatRule();

    @Test
    @Repeat(10)
    public void testMyCode() {
        //your test code goes here
    }
}

Repeat.java

import static java.lang.annotation.ElementType.ANNOTATION_TYPE;
import static java.lang.annotation.ElementType.METHOD;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention( RetentionPolicy.RUNTIME )
@Target({ METHOD, ANNOTATION_TYPE })
public @interface Repeat {
    int value() default 1;
}

RepeatRule.java

import org.junit.rules.TestRule;
import org.junit.runner.Description;
import org.junit.runners.model.Statement;

public class RepeatRule implements TestRule {

    private static class RepeatStatement extends Statement {
        private final Statement statement;
        private final int repeat;    

        public RepeatStatement(Statement statement, int repeat) {
            this.statement = statement;
            this.repeat = repeat;
        }

        @Override
        public void evaluate() throws Throwable {
            for (int i = 0; i < repeat; i++) {
                statement.evaluate();
            }
        }

    }

    @Override
    public Statement apply(Statement statement, Description description) {
        Statement result = statement;
        Repeat repeat = description.getAnnotation(Repeat.class);
        if (repeat != null) {
            int times = repeat.value();
            result = new RepeatStatement(statement, times);
        }
        return result;
    }
}

PowerMock

Using this solution with @RunWith(PowerMockRunner.class), requires updating to Powermock 1.6.5 (which includes a patch).

System.setProperty("javax.net.ssl.trustStore", "C:\\Users\\user-id\\Desktop\\tomcat\\cacerts");
System.setProperty("javax.net.ssl.trustStorePassword", "passwd");

You have to add the above two lines to your code. It is not able to find the truststore.

Are you sure that your configuration file (web.config) is at the right place and the connection string is really in the (generated) file? If you publish your file, the content of web.release.config might be copied.

The configuration and the access to the Connection string looks all right to me. I would always add a providername

<connectionStrings>
  <add name="Dbconnection" 
       connectionString="Server=localhost; Database=OnlineShopping; 
       Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>

Try:

<?php 
// Tell me the root folder path.
// You can also try this one
// $HOME = $_SERVER["DOCUMENT_ROOT"];
// Or this
// dirname(__FILE__)
$HOME = dirname(__FILE__);

// Is this a Windows host ? If it is, change this line to $WIN = 1;
$WIN = 0;

// That's all I need

textview.setTypeface(Typeface.DEFAULT_BOLD);

setTypeface is the Attribute textStyle.

As Shankar V added, to preserve the previously set typeface attributes you can use:

textview.setTypeface(textview.getTypeface(), Typeface.BOLD);

A struct (without a typedef) often needs to (or should) be with the keyword struct when used.

struct A;                      // forward declaration
void function( struct A *a );  // using the 'incomplete' type only as pointer

If you typedef your struct you can leave out the struct keyword.

typedef struct A A;          // forward declaration *and* typedef
void function( A *a );

Note that it is legal to reuse the struct name

Try changing the forward declaration to this in your code:

typedef struct context context;

It might be more readable to do add a suffix to indicate struct name and type name:

typedef struct context_s context_t;

SELECT  username, AVG(rating) as TheAverage, COUNT(*) as TheCount
FROM    ratings
        WHERE month='Aug'
        AND username COLLATE latin1_general_ci IN
        (
        SELECT  username
        FROM    users
        WHERE   gender = 1
        )
GROUP BY
        username
HAVING
        TheCount > 4
ORDER BY
        TheAverage DESC, TheCount DESC;

This is a highly inefficient way of doing it. You can use the merge statement and then there's no need for cursors, looping or (if you can do without) PL/SQL.

MERGE INTO studLoad l
USING ( SELECT studId, studName FROM student ) s
ON (l.studId = s.studId)
WHEN MATCHED THEN
  UPDATE SET l.studName = s.studName
   WHERE l.studName != s.studName
WHEN NOT MATCHED THEN 
INSERT (l.studID, l.studName)
VALUES (s.studId, s.studName)

Make sure you commit, once completed, in order to be able to see this in the database.

To actually answer your question I would do it something like as follows. This has the benefit of doing most of the work in SQL and only updating based on the rowid, a unique address in the table.

It declares a type, which you place the data within in bulk, 10,000 rows at a time. Then processes these rows individually.

However, as I say this will not be as efficient as merge.

declare

   cursor c_data is
    select b.rowid as rid, a.studId, a.studName
      from student a
      left outer join studLoad b
        on a.studId = b.studId
       and a.studName <> b.studName
           ;

   type t__data is table of c_data%rowtype index by binary_integer;
   t_data t__data;

begin

   open c_data;
   loop
      fetch c_data bulk collect into t_data limit 10000;

      exit when t_data.count = 0;

      for idx in t_data.first .. t_data.last loop
         if t_data(idx).rid is null then
            insert into studLoad (studId, studName)
            values (t_data(idx).studId, t_data(idx).studName);
         else
            update studLoad
               set studName = t_data(idx).studName
             where rowid = t_data(idx).rid
                   ;
         end if;
      end loop;

   end loop;
   close c_data;

end;

Git reset has 5 main modes: soft, mixed, merged, hard, keep. The difference between them is to change or not change head, stage (index), working directory.

Git reset --hard will change head, index and working directory.
Git reset --soft will change head only. No change to index, working directory.

So in other words if you want to undo your commit, --soft should be good enough. But after that you still have the changes from bad commit in your index and working directory. You can modify the files, fix them, add them to index and commit again.

With the --hard, you completely get a clean slate in your project. As if there hasn't been any change from the last commit. If you are sure this is what you want then move forward. But once you do this, you'll lose your last commit completely. (Note: there are still ways to recover the lost commit).

Recently, AWS added a feature called Sessions Manager to the Systems Manager service that allows one to SSH into an instance without needing to setup a private key or opening up port 22. I believe authentication is done with IAM and optionally MFA.

You can find out more about it here:

https://aws.amazon.com/blogs/aws/new-session-manager/

lines is a list. re.findall() doesn't take lists.

From help(file.readlines). I.e. readlines() is for loops/iterating:

readlines(...)
    readlines([size]) -> list of strings, each a line from the file.

Above Spring 4, there is no need to configure MappingJacksonHttpMessageConverter if you only intend to configure ObjectMapper.

(configure MappingJacksonHttpMessageConverter will cause you to lose other MessageConverter)

You just need to do:

public class MyObjectMapper extends ObjectMapper {

    private static final long serialVersionUID = 4219938065516862637L;

    public MyObjectMapper() {
        super();
        enable(SerializationFeature.INDENT_OUTPUT);
    }       
}

And in your Spring configuration, create this bean:

@Bean 
public MyObjectMapper myObjectMapper() {        
    return new MyObjectMapper();
}

First, if you are unfamiliar with the command line, try using phpmyadmin from your webbrowser. This will make sure you actually have a mysql database created and a username.

This is how you connect from the command line (bash):

mysql -h hostname -u username -p database_name

For example:

fabio@crunchbang ~ $ mysql -h 127.0.0.1 -u fabio -p fabiodb

In Python, this:

my_object.method("foo")

...is syntactic sugar, which the interpreter translates behind the scenes into:

MyClass.method(my_object, "foo")

...which, as you can see, does indeed have two arguments - it's just that the first one is implicit, from the point of view of the caller.

This is because most methods do some work with the object they're called on, so there needs to be some way for that object to be referred to inside the method. By convention, this first argument is called self inside the method definition:

class MyNewClass:

    def method(self, arg):
        print(self)
        print(arg)

If you call method("foo") on an instance of MyNewClass, it works as expected:

>>> my_new_object = MyNewClass()
>>> my_new_object.method("foo")
<__main__.MyNewClass object at 0x29045d0>
foo

Occasionally (but not often), you really don't care about the object that your method is bound to, and in that circumstance, you can decorate the method with the builtin staticmethod() function to say so:

class MyOtherClass:

    @staticmethod
    def method(arg):
        print(arg)

...in which case you don't need to add a self argument to the method definition, and it still works:

>>> my_other_object = MyOtherClass()
>>> my_other_object.method("foo")
foo

In Rails 3.2.18, :decimal turns into :integer when using SQLServer, but it works fine in SQLite. Switching to :float solved this issue for us.

The lesson learned is "always use homogeneous development and deployment databases!"

I think the following code is close to what you want

x    <- c(0.1, 0.2, 0.3, 0.4, 0.5)
y    <- c(1, 2, 3, 4, 5)
zfun <- function(a,b) {a*b * ( 0.9 + 0.2*runif(a*b) )}
z    <- outer(x, y, FUN="zfun")

It gives data like this (note that x and y are both increasing)

> x
[1] 0.1 0.2 0.3 0.4 0.5
> y
[1] 1 2 3 4 5
> z
          [,1]      [,2]      [,3]      [,4]      [,5]
[1,] 0.1037159 0.2123455 0.3244514 0.4106079 0.4777380
[2,] 0.2144338 0.4109414 0.5586709 0.7623481 0.9683732
[3,] 0.3138063 0.6015035 0.8308649 1.2713930 1.5498939
[4,] 0.4023375 0.8500672 1.3052275 1.4541517 1.9398106
[5,] 0.5146506 1.0295172 1.5257186 2.1753611 2.5046223

and a graph like

persp(x, y, z)

You can find those maven properties in the super pom.

You find the jar here:

${M2_HOME}/lib/maven-model-builder-3.0.3.jar

Open the jar with 7-zip or some other archiver (or use the jar tool).

Navigate to

org/apache/maven/model

There you'll find the pom-4.0.0.xml.

It contains all those "short cuts":

<project>
    ...
    <build>
        <directory>${project.basedir}/target</directory>
        <outputDirectory>${project.build.directory}/classes</outputDirectory>

Update

After some lobbying I am adding a link to the pom-4.0.0.xml. This allows you to see the properties without opening up the local jar file.

Remember to include System.Diagnostics

ProcessStartInfo startInfo = new ProcessStartInfo("myfile.exe");        // exe file
startInfo.WorkingDirectory = @"C:\..\MyFile\bin\Debug\netcoreapp3.1\"; // exe folder

//here you add your arguments
startInfo.ArgumentList.Add("arg0");       // First argument          
startInfo.ArgumentList.Add("arg2");       // second argument
startInfo.ArgumentList.Add("arg3");       // third argument
Process.Start(startInfo);                 

You can have multiple registries for scoped packages in your .npmrc file. For example:

@polymer:registry=<url register A>
registry=http://localhost:4873/

Packages under @polymer scope will be received from https://registry.npmjs.org, but the rest will be received from your local NPM.

Suppose you want to create a vector x whose length is zero. Now let v be any vector.

> v<-c(4,7,8)
> v
[1] 4 7 8
> x<-v[0]
> length(x)
[1] 0

If you're in a Navigation Controller:

ViewController *viewController = [[ViewController alloc] init];
[self.navigationController pushViewController:viewController animated:YES];

or if you just want to present a new view:

ViewController *viewController = [[ViewController alloc] init];    
[self presentViewController:viewController animated:YES completion:nil];

In C++ copying the object means cloning. There is no any special cloning in the language.

As the standard suggests, after copying you should have 2 identical copies of the same object.

There are 2 types of copying: copy constructor when you create object on a non initialized space and copy operator where you need to release the old state of the object (that is expected to be valid) before setting the new state.

If you would like to redirect the user after the alert, do this:

echo ("<script LANGUAGE='JavaScript'>
          window.alert('Succesfully Updated');
          window.location.href='<URL to redirect to>';
       </script>");

Try the following.

$d = [datetime](Get-ItemProperty -Path $source -Name LastWriteTime).lastwritetime

This is part of the item property weirdness. When you run Get-ItemProperty it does not return the value but instead the property. You have to use one more level of indirection to get to the value.

The best way to use https and avoid security issues is to use Firefox (or another tool) and download the certificate to your server. This webpage helped me a lot, and these were the steps that worked for me:

1) Open in Firefox the URL you're gonna use with CURL

2) On the address bar click on the padlock > more information (FF versions can have different menus, just find it). Click the View certificate button > Details tab.

3) Highlight the "right" certificate in Certificate hierarchy. In my case it was the second of three, called "cPanel, Inc. Certification Authority". I just discovered the right one by "trial and error" method.

4) Click the Export button. In my case the one who worked was the file type "PEM with chains" (again by trial and error method).

5) Then in your PHP script add:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);    
curl_setopt($ch, CURLOPT_CAINFO, [PATH_TO_CRT_FILE]);

In addition I'd say that we must pay attention on the fact that these steps will probably need to be redone once a year or whenever the URL certificate is replaced or renewed.

You can simply use this:

'07311954' in df.date.values which returns True or False

Here is the further explanation:

In pandas, using in check directly with DataFrame and Series (e.g. val in df or val in series ) will check whether the val is contained in the Index.

BUT you can still use in check for their values too (instead of Index)! Just using val in df.col_name.values or val in series.values. In this way, you are actually checking the val with a Numpy array.

And .isin(vals) is the other way around, it checks whether the DataFrame/Series values are in the vals. Here vals must be set or list-like. So this is not the natural way to go for the question.

This should display 'Tue':

new SimpleDateFormat("EEE").format(new Date());

This should display 'Tuesday':

new SimpleDateFormat("EEEE").format(new Date());

This should display 'T':

new SimpleDateFormat("EEEEE").format(new Date());

So your specific example would be:

new SimpleDateFormat("yyyy-MM-EEE").format(new Date());

From the keytool man - it imports certificate chain, if input is given in PKCS#7 format, otherwise only the single certificate is imported. You should be able to convert certificates to PKCS#7 format with openssl, via openssl crl2pkcs7 command.

Here's a macro that allows you to shuffle selected cells in a column:

Option Explicit

Sub ShuffleSelectedCells()
  'Do nothing if selecting only one cell
  If Selection.Cells.Count = 1 Then Exit Sub
  'Save selected cells to array
  Dim CellData() As Variant
  CellData = Selection.Value
  'Shuffle the array
  ShuffleArrayInPlace CellData
  'Output array to spreadsheet
  Selection.Value = CellData
End Sub

Sub ShuffleArrayInPlace(InArray() As Variant)
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
' ShuffleArrayInPlace
' This shuffles InArray to random order, randomized in place.
' Source: http://www.cpearson.com/excel/ShuffleArray.aspx
' Modified by Tom Doan to work with Selection.Value two-dimensional arrays.
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
  Dim J As Long, _
    N As Long, _
    Temp As Variant
  'Randomize
  For N = LBound(InArray) To UBound(InArray)
    J = CLng(((UBound(InArray) - N) * Rnd) + N)
    If J <> N Then
      Temp = InArray(N, 1)
      InArray(N, 1) = InArray(J, 1)
      InArray(J, 1) = Temp
    End If
  Next N
End Sub

You can read the comments to see what the macro is doing. Here's how to install the macro:

1. Open the VBA editor (Alt + F11).
2. Right-click on "ThisWorkbook" under your currently open spreadsheet (listed in parentheses after "VBAProject") and select Insert / Module.
3. Paste the code above and save the spreadsheet.

Now you can assign the "ShuffleSelectedCells" macro to an icon or hotkey to quickly randomize your selected rows (keep in mind that you can only select one column of rows).

You just need to do it in correct syntax. Let me give you a minimal example I just did with Python interactive shell:

>>> class MyNameClass():
...   def __init__(self, myname):
...       print myname
... 
>>> p1 = MyNameClass('John')
John

In the hexadecimal it can't get a negative value. So it shows it like ffffffff.

The advantage to using the unsigned version (when you know the values contained will be non-negative) is that sometimes the computer will spot errors for you (the program will "crash" when a negative value is assigned to the variable).

There is another way of controlling error handling that works well for loops. Create a string variable called here and use the variable to determine how a single error handler handles the error.

The code template is:

On error goto errhandler

Dim here as String

here = "in loop"
For i = 1 to 20 
    some code
Next i

afterloop:
here = "after loop"
more code

exitproc:    
exit sub

errhandler:
If here = "in loop" Then 
    resume afterloop
elseif here = "after loop" Then
    msgbox "An error has occurred" & err.desc
    resume exitproc
End if

Try in yourbatch

set "batchisin=%~dp0"

which should set the variable to your batch's location.

Do you mean

.*

. any character, except newline character, with dotall mode it includes also the newline characters

* any amount of the preceding expression, including 0 times

Try this. I set the blue box to float right, gave left and right a fixed height, and added a white border on the right of the left div. Also added rounded corners to more match your example (These won't work in ie 8 or less). I also took out the position: relative. You don't need it. Block level elements are set to position relative by default.

See it here: http://jsfiddle.net/ZSgLJ/

#left {
  float: left;
  width: 44%;
  margin: 0;
  padding: 0;
  border-right: 1px solid white;
  height:400px;
}

#right {
  position: relative;
  float: right;
  width: 49%;
  margin: 0;
  padding: 0;
  height:400px;
}

#blue_box {
  background-color:blue;
  border-radius: 10px;
  -moz-border-radius:10px;
  -webkit-border-radius: 10px;
  width: 45%;
  min-width: 400px;
  max-width: 600px;
  padding: 2%;
  float: right;
}

Assuming your sample data is correct, your givenname, and other entries wrapped in brackets are arrays in JS... you'll want to use List for those data types. and List for say accountstatusexpmaxdate... I think you example has the dates incorrectly formatted though, so uncertain as to what else is incorrect in your example.

This is an old post, but wanted to make note of the issues.

Let's fit the model:

> library(ISwR)
> fit <- lm(metabolic.rate ~ body.weight, rmr)
> summary(fit)

Call:
lm(formula = metabolic.rate ~ body.weight, data = rmr)

Residuals:
    Min      1Q  Median      3Q     Max 
-245.74 -113.99  -32.05  104.96  484.81 

Coefficients:
            Estimate Std. Error t value Pr(>|t|)    
(Intercept) 811.2267    76.9755  10.539 2.29e-13 ***
body.weight   7.0595     0.9776   7.221 7.03e-09 ***
---
Signif. codes:  0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1 

Residual standard error: 157.9 on 42 degrees of freedom
Multiple R-squared: 0.5539, Adjusted R-squared: 0.5433 
F-statistic: 52.15 on 1 and 42 DF,  p-value: 7.025e-09 

The 95% confidence interval for the slope is the estimated coefficient (7.0595) ± two standard errors (0.9776).

This can be computed using confint:

> confint(fit, 'body.weight', level=0.95)
               2.5 % 97.5 %
body.weight 5.086656 9.0324

can also use:

$("input.DateFrom").datepicker({
    minDate: 'today'
});
