Programs & Examples On #Iis express

To open IIS Manager, click Start, type inetmgr in the Search Programs and Files box, and then press ENTER.

if the IIS Manager doesn't open that means you need to install it.

So, Follow the instruction at this link: https://docs.microsoft.com/en-us/iis/install/installing-iis-7/installing-iis-on-windows-vista-and-windows-7

In my case I had to open the file:

C:\...\Documents\IISExpress\config\applicationhost.config

I had this inside the file:

  <authentication>
  <anonymousAuthentication enabled="true" User="" />

I just removed the User="" part. I really don't know how this thing got there... :)

Note: Make sure you have something like this in the end of applicationhost.config:

   .
   .
   .
   <location path="MyCompany.MyProjectName.Web">
        <system.webServer>
            <security>
                <authentication>
                    <anonymousAuthentication enabled="true" />
                    <windowsAuthentication enabled="false" />
                </authentication>
            </security>
        </system.webServer>
    </location>
</configuration>

Now I can access the login page as expected.

Right click on your MVC Project. Go to Properties. Go to the Web tab.
Change the port number in the Project Url. Example. localhost:50645
Changing the bold number, 50645, to anything else will change the port the site runs under.
Press the Create Virtual Directory button to complete the process.

One time, after a power outage, I had to face the same slowness problem each time a breakpoint was hit or a Exception was thrown.

I had the vague remembering that the "suo" file (in the same directory as the "sln" solution file) can be corrupted and make everything slow down.

I deleted my "suo" files and everything was ok. The .suo files deletion is harmless and only implies to recreate my windows layout plus the starting project and a few other non critical customizations.

At the start, Try to disable your firewall. It helped me. The Eset Smart Security 5 blocked it.

An excellent answer given by msigman. I just want to add that in windows 10 you can find IIS Express System Tray (32 bit) process under Visual Studio process:

For me using this, relatively simple, and straight forward:

Download the Visual Studio Extension by searching for 'Conveyor' in the Extensions dialog. Then just install.

form: https://marketplace.visualstudio.com/items?itemName=vs-publisher-1448185.ConveyorbyKeyoti

Visual Studio 2010 SP1 and 2012 added support for IIS Express eliminating the need to edit angle brackets.

1. If you haven't already, right-click a web-flavored project and select "Use IIS Express...".
2. Once complete, select the web project and press F4 to focus the Properties panel.
3. Set the "Windows Authentication" property to Enabled, and the "Anonymous Authentication" property to Disabled.

I believe this solution is superior to the vikomall's options.

• Option #1 is a global change for all IIS Express sites.
• Option #2 leaves development cruft in the web.config.
  • Further, it will probably lead to an error when deployed to IIS 7.5 unless you follow the "unlock" procedure on your IIS server's applicationHost.config.

The UI-based solution above uses site-specific location elements in IIS Express's applicationHost.config leaving the app untouched.

More information here: http://msdn.microsoft.com/en-us/magazine/hh288080.aspx

This publish profile setting fixed for me:

Configure Publish Profile -> Settings -> Site Extensions Options ->

• [x] Install ASP.NET Core Site Extension.

Open your csproj with for example Notepad ++ and scroll down to DevelopmentServerPort. Change it to something else as long as it's above 1024 like rekommended (so for example 22312). Also change the IISUrl to http://localhost:22312/. Save your changes and restart the project.

Following Jaro's advice, I was able to get this working under Windows XP and IIS Express (installed via Web Matrix) with a small modification and was not limited to only localhost. It's just a matter of setting the bindings correctly.

1. Use WebMatrix to create a new site from folder in your web application root.
2. Close WebMatrix.
3. Open %USERPROFILE%\My Documents\IISExpress\config\applicationhost.config (Windows XP. Vista and 7 paths will be similar) and edit the site definition in the <sites> config block to be along the lines of the following:
   
   

   <site name="DevExample" id="997005936">
       <application path="/" applicationPool="Clr2IntegratedAppPool">
           <virtualDirectory
               path="/"
               physicalPath="C:\path\to\application\root" />
       </application>
       <bindings>
           <binding
               protocol="http"
               bindingInformation="*:80:dev.example.com" />
       </bindings>
       <applicationDefaults applicationPool="Clr2IntegratedAppPool" />
   </site>

If running MVC, then keep the applicationPool set to one of the "Integrated" options.

Try following steps:

1. delete the IISExpress folder as @Yehuda Shapira said
2. restart computer
3. delete the .vs folder in project

Have a good luck!

To come full circle and include all versions of Visual Studio, @Myster originally stated that;

Pre Visual Studio 2015 the paths to applicationhost.config were:

%userprofile%\documents\iisexpress\config\applicationhost.config
%userprofile%\my documents\iisexpress\config\applicationhost.config

Visual Studio 2015/2017 path can be found at: (credit: @Talon)

$(solutionDir)\.vs\config\applicationhost.config

Visual Studio 2019 path can be found at: (credit: @Talon)

$(solutionDir)\.vs\config\$(ProjectName)\applicationhost.config

But the part that might get some people is that the project settings in the .sln file can repopulate the applicationhost.config for Visual Studio 2015+. (credit: @Lex Li)

So, if you make a change in the applicationhost.config you also have to make sure your changes match here:

$(solutionDir)\ProjectName.sln

The two important settings should look like:

Project("{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}") = "ProjectName", "ProjectPath\", "{XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}"

and

VWDPort = "Port#"

What is important here is that the two settings in the .sln must match the name and bindingInformation respectively in the applicationhost.config file if you plan on making changes. There may be more places that link these two files and I will update as I find more links either by comments or more experience.

As solution could be also considering encoding to a format which doesn't contain symbol., as base64.

In js should be added

btoa(parameter); 

In controller

byte[] bytes = Convert.FromBase64String(parameter);
string parameter= Encoding.UTF8.GetString(bytes);

A new option is Jexus Manager for IIS Express,

https://blog.lextudio.com/2014/10/jexus-manager-for-iis-express/

It is just the management tool you know how to use.

It appears that the right answer is provided by user3149240 above. However, As Neil Watson pointed out, the applicationhost.config file is at play here.

The changes can actually be made in the VS Property pane or in the file albeit in a different spot. Near the bottom of the applicationhost.config file is a set of location elements. Each app for IIS Express seems to have one of these. Changing the settings in the UI updates this section of the file. So, you can either change the settings through the UI or modify this file.

Here is an example with anonymous auth off and Windows auth on:

<location path="MyApp">
    <system.webServer>
        <security>
            <authentication>
                <windowsAuthentication enabled="true" />
                <anonymousAuthentication enabled="false" />
            </authentication>
        </security>
    </system.webServer>
</location>

This is equivalent in the VS UI to:

Anonymous Authentication: Disabled
Windows Authentication: Enabled

From the links the others have posted, I'm not seeing an option. -- I just use powershell to kill it -- you can save this to a Stop-IisExpress.ps1 file:

get-process | where { $_.ProcessName -like "IISExpress" } | stop-process

There's no harm in it -- Visual Studio will just pop a new one up when it wants one.

If you are using 64 bit machine

Go to Visual Studio > Tools Menu > Options

I had this issue with JetBrains Rider, specifically for port 80 and 90 bit it was working with other ports as well as visual studio.

after running as admin this resolved the issue.

To solve the problem, double-click the "MIME Types" configuration option while having IIS root node selected in the left panel and click "Add..." link in the Actions panel on the right. This will bring up the following dialog. Add .woff file extension and specify "application/x-font-woff" as the corresponding MIME type:

Follow same for woff2 with application/x-font-woff2

I solved a similar problem by listing bound IP addresses in a cmd window running as admin:

netsh http show iplisten

Then, one by one, blowing them all away:

netsh http delete iplisten ipaddress=127.0.0.200
netsh http delete iplisten ipaddress=127.0.0.2
...

None of the listed solutions worked for me. Problem was some sort of conflicting state in local applicationhost.config file. Fix is easy, just delete one in your solution. For VS2015 it should be located in <path_to_your_solution>\Solution\.vs\config\. When you launch Debug, VS will recreate that file based on settings in your project file.

In my case, it was caused by an infinite loop/stack overflow.

As mentioned above, edit the application host.config. An easy way to find this is run your site in VS using IIS Express. Right click the systray icon, show all applications. Choose your site, and then click on the config link at the bottom to open it.

I'd suggest adding another binding entry, and leave the initial localhost one there. This additional binding will appear in the IIS Express systray as a separate application under the site.

To avoid having to run VS as admin (lots of good reasons not to run as admin), add a netsh rule as follows (obviously replacing the IP and port with your values) - you'll need an admin cmd.exe for this, it only needs to be run once:

netsh http add urlacl url=http://192.168.1.121:51652/ user=\Everyone

netsh can add rules like url=http://+:51652/ but I failed to get this to place nicely with IIS Express. You can use netsh http show urlacl to list existing rules, and they can be deleted with netsh http delete urlacl url=blah.

Further info: http://msdn.microsoft.com/en-us/library/ms733768.aspx

Additionally to Bruno's answer I ended up registering the same port for localhost. Otherwise VS2015 was giving me Access Denied error on server start.

netsh http add urlacl url=http://localhost:{port}/ user=everyone

May be it's because I have binding for localhost in aplicationhost.config also.

I did the following

1. Delete my db.sqlite3 database
2. python manage.py makemigrations
3. python manage.py migrate

It renewed the database and fixed the issues without affecting my project. Please note you might need to do python manage.py createsuperuser because it will affect all your objects being created.

As of AngularJS 1.1.3, you can now do exactly what you want using the new catch-all parameter.

https://github.com/angular/angular.js/commit/7eafbb98c64c0dc079d7d3ec589f1270b7f6fea5

From the commit:

This allows routeProvider to accept parameters that matches substrings even when they contain slashes if they are prefixed with an asterisk instead of a colon. For example, routes like edit/color/:color/largecode/*largecode will match with something like this http://appdomain.com/edit/color/brown/largecode/code/with/slashs.

I have tested it out myself (using 1.1.5) and it works great. Just keep in mind that each new URL will reload your controller, so to keep any kind of state, you may need to use a custom service.

It currently only works for the built in system frameworks. If you use #import like apple still do importing the UIKit framework in the app delegate it is replaced (if modules is on and its recognised as a system framework) and the compiler will remap it to be a module import and not an import of the header files anyway. So leaving the #import will be just the same as its converted to a module import where possible anyway

AFAIK there is no property for that in the specs, but here is a trick I’ve been using: set the container element ( the one with display:flex ) to justify-content:space-around Then add an extra element between the first and second item and set it to flex-grow:10 (or some other value that works with your setup)

Edit: if the items are tightly aligned it's a good idea to add flex-shrink: 10; to the extra element as well, so the layout will be properly responsive on smaller devices.

Wizard

Have you tried setting the height and width of the extra div, I know that on a project I am working on JS won't put anything in the div unless I have the height and width already set.

I used your code and hard coded the height and width and it shows up for me and without it doesn't show.

<body>
    <div style="height:500px; width:500px;"> <!-- ommiting the height and width will not show the map -->
         <div id="map-canvas"></div>
    </div>
</body> 

I would recommend either hard coding it in or assigning the div an ID and then add it to your CSS file.

Since Google takes you to this post when searching for C# Web API Referrer here's the deal: Web API uses a different type of Request from normal MVC Request called HttpRequestMessage which does not include UrlReferrer. Since a normal Web API request does not include this information, if you really need it, you must have your clients go out of their way to include it. Although you could make this be part of your API Object, a better way is to use Headers.

First, you can extend HttpRequestMessage to provide a UrlReferrer() method:

public static string UrlReferrer(this HttpRequestMessage request)
{
    return request.Headers.Referrer == null ? "unknown" : request.Headers.Referrer.AbsoluteUri;
}

Then your clients need to set the Referrer Header to their API Request:

// Microsoft.AspNet.WebApi.Client
client.DefaultRequestHeaders.Referrer = new Uri(url);

And now the Web API Request includes the referrer data which you can access like this from your Web API:

Request.UrlReferrer();

Try using the data option of the $.ajax function. More info here.

$('#btnSaveComments').click(function () {
    var comments = $('#txtComments').val();
    var selectedId = $('#hdnSelectedId').val();

    $.ajax({
        url: '<%: Url.Action("SaveComments")%>',
        data: { 'id' : selectedId, 'comments' : comments },
        type: "post",
        cache: false,
        success: function (savingStatus) {
            $("#hdnOrigComments").val($('#txtComments').val());
            $('#lblCommentsNotification').text(savingStatus);
        },
        error: function (xhr, ajaxOptions, thrownError) {
            $('#lblCommentsNotification').text("Error encountered while saving the comments.");
        }
    });
});

For me, the gem lock file was specifying an older version of cocoapods than the one I had installed. I had to re-branch and run bundle exec pod install instead of pod install

The theoretical limit may be 2,147,483,647, but the practical limit is nowhere near that. Since no single object in a .NET program may be over 2GB and the string type uses UTF-16 (2 bytes for each character), the best you could do is 1,073,741,823, but you're not likely to ever be able to allocate that on a 32-bit machine.

This is one of those situations where "If you have to ask, you're probably doing something wrong."

if you want to sort dates

   usort($threads,function($first,$second){
        return strtotime($first->dateandtime) < strtotime($second->dateandtime);
    });

Well actually you will need to return something like this because toString has to return a string

public String toString() {
 return "Name :" + this.name + "whatever :" + this.whatever + "";
}

and you actually do something wrong in the constructer you set the variable the user set to the name while you need to do the opposite. What you shouldn't do

n = this.name

What you should do

this.name = n

Hopes this helps thanks

Example. To find number of vowels within the string

var word='Web Development Tutorial';
var vowels='[aeiou]'; 
var re = new RegExp(vowels, 'gi');
var arr = word.match(re);
document.write(arr.length);

At the time of my writing this answer, the accepted answer to this question appears to state that browsers are not required to delete a cookie when receiving a replacement cookie whose Expires value is in the past. That claim is false. Setting Expires to be in the past is the standard, spec-compliant way of deleting a cookie, and user agents are required by spec to respect it.

Using an Expires attribute in the past to delete a cookie is correct and is the way to remove cookies dictated by the spec. The examples section of RFC 6255 states:

Finally, to remove a cookie, the server returns a Set-Cookie header with an expiration date in the past. The server will be successful in removing the cookie only if the Path and the Domain attribute in the Set-Cookie header match the values used when the cookie was created.

The User Agent Requirements section includes the following requirements, which together have the effect that a cookie must be immediately expunged if the user agent receives a new cookie with the same name whose expiry date is in the past

11. If [when receiving a new cookie] the cookie store contains a cookie with the same name, domain, and path as the newly created cookie:

    1. ...
    2. ...
    3. Update the creation-time of the newly created cookie to match the creation-time of the old-cookie.
    4. Remove the old-cookie from the cookie store.

12. Insert the newly created cookie into the cookie store.

A cookie is "expired" if the cookie has an expiry date in the past.

The user agent MUST evict all expired cookies from the cookie store if, at any time, an expired cookie exists in the cookie store.

Points 11-3, 11-4, and 12 above together mean that when a new cookie is received with the same name, domain, and path, the old cookie must be expunged and replaced with the new cookie. Finally, the point below about expired cookies further dictates that after that is done, the new cookie must also be immediately evicted. The spec offers no wiggle room to browsers on this point; if a browser were to offer the user the option to disable cookie expiration, as the accepted answer suggests some browsers do, then it would be in violation of the spec. (Such a feature would also have little use, and as far as I know it does not exist in any browser.)

Why, then, did the OP of this question observe this approach failing? Though I have not dusted off a copy of Internet Explorer to check its behaviour, I suspect it was because the OP's Expires value was malformed! They used this value:

expires=Thu, Jan 01 1970 00:00:00 UTC;

However, this is syntactically invalid in two ways.

The syntax section of the spec dictates that the value of the Expires attribute must be a

rfc1123-date, defined in [RFC2616], Section 3.3.1

Following the second link above, we find this given as an example of the format:

Sun, 06 Nov 1994 08:49:37 GMT

and find that the syntax definition...

1. requires that dates be written in day month year format, not month day year format as used by the question asker.

   Specifically, it defines rfc1123-date as follows:

   rfc1123-date = wkday "," SP date1 SP time SP "GMT"
   

   and defines date1 like this:

   date1        = 2DIGIT SP month SP 4DIGIT
                ; day month year (e.g., 02 Jun 1982)
   

and

2. doesn't permit UTC as a timezone.

   The spec contains the following statement about what timezone offsets are acceptable in this format:

   All HTTP date/time stamps MUST be represented in Greenwich Mean Time (GMT), without exception.

   What's more if we dig deeper into the original spec of this datetime format, we find that in its initial spec in https://tools.ietf.org/html/rfc822, the Syntax section lists "UT" (meaning "universal time") as a possible value, but does not list not UTC (Coordinated Universal Time) as valid. As far as I know, using "UTC" in this date format has never been valid; it wasn't a valid value when the format was first specified in 1982, and the HTTP spec has adopted a strictly more restrictive version of the format by banning the use of all "zone" values other than "GMT".

If the question asker here had instead used an Expires attribute like this, then:

expires=Thu, 01 Jan 1970 00:00:00 GMT;

then it would presumably have worked.

Old question but worth adding an answer if using .NET Core 3.0 or later. JSON serialization/deserialization is built into the framework (System.Text.Json), so you don't have to use third party libraries any more. Here's an example based off the top answer given by @Icarus

using System;
using System.Collections.Generic;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var json = "[{\"Name\":\"John Smith\", \"Age\":35}, {\"Name\":\"Pablo Perez\", \"Age\":34}]";

            // use the built in Json deserializer to convert the string to a list of Person objects
            var people = System.Text.Json.JsonSerializer.Deserialize<List<Person>>(json);

            foreach (var person in people)
            {
                Console.WriteLine(person.Name + " is " + person.Age + " years old.");
            }
        }

        public class Person
        {
            public int Age { get; set; }
            public string Name { get; set; }
        }
    }
}

You can try below code to solve your problem:

Thanks, Ketan T

i have used this and solved my

-webkit-appearance:none;

1.  SELECT MAX(Id) FROM Table

Try calling it like: obj.some_function( '1', 2, '3', g="foo", h="bar" ). After the required positional arguments, you can specify specific optional arguments by name.

They are the same when used for output, e.g. with printf.

However, these are different when used as input specifier e.g. with scanf, where %d scans an integer as a signed decimal number, but %i defaults to decimal but also allows hexadecimal (if preceded by 0x) and octal (if preceded by 0).

So 033 would be 27 with %i but 33 with %d.

Once I designed an API which main resource was people. Usually users would request filtered people so, to prevent users to call something like /people?settlement=urban every time, I implemented /people/urban which later enabled me to easily add /people/rural. Also this allows to access the full /people list if it would be of any use later on. In short, my reasoning was to add a path to common subsets

From here:

Aliases for common queries

To make the API experience more pleasant for the average consumer, consider packaging up sets of conditions into easily accessible RESTful paths. For example, the recently closed tickets query above could be packaged up as GET /tickets/recently_closed

• My List: L=[0, 23, 234, 89, None, 0, 35, 9]
• Code_result: [k for k in L if (k is None)==False]
• Result: [0, 23, 234, 89, 0, 35, 9]

fs.exists(path, callback) and fs.existsSync(path) are deprecated now, see https://nodejs.org/api/fs.html#fs_fs_exists_path_callback and https://nodejs.org/api/fs.html#fs_fs_existssync_path.

To test the existence of a file synchronously one can use ie. fs.statSync(path). An fs.Stats object will be returned if the file exists, see https://nodejs.org/api/fs.html#fs_class_fs_stats, otherwise an error is thrown which will be catched by the try / catch statement.

var fs = require('fs'),
  path = '/path/to/my/file',
  stats;

try {
  stats = fs.statSync(path);
  console.log("File exists.");
}
catch (e) {
  console.log("File does not exist.");
}

This seems simpler to me

<li *ngFor="let item of list | slice:0:10; let i=index" class="dropdown-item" (click)="onClick(item)">{{item.text}}</li>

Closer to your approach

<ng-container *ngFor="let item of list" let-i="index">
  <li class="dropdown-item" (click)="onClick(item)" *ngIf="i<11">{{item.text}}</li>
</ng-container>

http://transfonter.org/ will do the job for you. Just upload your .ttc and it will give you a folder with all the fonttypes in .ttf files.

There are multiple ways to achieve this:

1. By using --simulator flag
2. By using --udid flag

Firstly you need to list all the available devices. To list all the devices run

xcrun simctl list device

This will give output as follows:

These are the available devices for iOS 13.0 onwards:

This example returns the draft field value every time the hidden draft field changes its value (chrome browser):

var h = document.querySelectorAll('input[type="hidden"][name="draft"]')[0];
//or jquery.....
//var h = $('input[type="hidden"][name="draft"]')[0];

observeDOM(h, 'n', function(draftValue){ 
  console.log('dom changed draftValue:'+draftValue);
});


var observeDOM = (function(){
var MutationObserver = window.MutationObserver || 
window.WebKitMutationObserver;

  return function(obj, thistime, callback){
    if(typeof obj === 'undefined'){
      console.log('obj is undefined');
      return;
    }

    if( MutationObserver ){

        // define a new observer
        var obs = new MutationObserver(function(mutations, observer){

            if( mutations[0].addedNodes.length || mutations[0].removedNodes.length ){

               callback('pass other observations back...');

            }else if(mutations[0].attributeName == "value" ){

               // use callback to pass back value of hidden form field                            
               callback( obj.value );

            }

        });

        // have the observer observe obj for changes in children
        // note 'attributes:true' else we can't read the input attribute value
        obs.observe( obj, { childList:true, subtree:true, attributes:true  });

       }
  };
})();

Demo Here

var e = jQuery.Event("keypress");
e.which = 13; //choose the one you want
e.keyCode = 13;
$("#theInputToTest").trigger(e);

You should remove .Value from all option buttons because option buttons don't hold the resultant value, the option group control does. If you omit .Value then the default interface will report the option button status, as you are expecting. You should write all relevant code under commandbutton_click events because whenever the commandbutton is clicked the option button action will run.

If you want to run action code when the optionbutton is clicked then don't write an if loop for that.

EXAMPLE:

Sub CommandButton1_Click
    If OptionButton1 = true then
        (action code...)
    End if
End sub

Sub OptionButton1_Click   
    (action code...)
End sub

You have to declare height of html to div1 elements together, like:

html,

You'll want to check HTML5 Differences from HTML4: W3C Working Group Note 9 December 2014 for the complete differences. There are many new elements and element attributes. Some elements were removed and others have different semantic value than before.

There are also APIs defined, such as the use of canvas, to help build the next generation of web apps and make sure implementations are standardized.

An alternative to @Steve's code.

DECLARE
  CURSOR foo_cur IS 
    SELECT NEEDED_FIELD WHERE condition ;
BEGIN
  FOR foo_rec IN foo_cur LOOP
     ...
  END LOOP;
EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END ;

The loop is not executed if there is no data. Cursor FOR loops are the way to go - they help avoid a lot of housekeeping. An even more compact solution:

DECLARE
BEGIN
  FOR foo_rec IN (SELECT NEEDED_FIELD WHERE condition) LOOP
     ...
  END LOOP;
EXCEPTION
  WHEN OTHERS THEN
    RAISE;
END ;

Which works if you know the complete select statement at compile time.

try:

 ALTER TABLE `user` CHANGE `id` `id` INT( 11 ) COMMENT 'id of user'  

There's a function called dropNamed() in Bernd Bischl's BBmisc package that does exactly this.

BBmisc::dropNamed(df, "x")

The advantage is that it avoids repeating the data frame argument and thus is suitable for piping in magrittr (just like the dplyr approaches):

df %>% BBmisc::dropNamed("x")

try

sudo chown mysql:mysql -R /var/lib/mysql

then start your mysql service

systemctl start mysqld

For C++ I suggest using CMarkup.

I was actually searching for a similar error and Google sent me here to this question. The error was:

The type arguments for method 'IModelExpressionProvider.CreateModelExpression(ViewDataDictionary, Expression>)' cannot be inferred from the usage

I spent maybe 15 minutes trying to figure it out. It was happening inside a Razor .cshtml view file. I had to comment portions of the view code to get to where it was barking since the compiler didn't help much.

<div class="form-group col-2">
    <label asp-for="Organization.Zip"></label>
    <input asp-for="Organization.Zip" class="form-control">
    <span asp-validation-for="Zip" class="color-type-alert"></span>
</div>

Can you spot it? Yeah... I re-checked it maybe twice and didn't get it at first!

See that the ViewModel's property is just Zip when it should be Organization.Zip. That was it.

So re-check your view source code... :-)

<div id="calendar"></div>
<script>
$(document).ready(function() {
    var days = [];

    $('#calendar').datepicker({
        dateFormat: 'yymmdd',
        showWeek: true, showOtherMonths: false, selectOtherMonths: false,
        navigationAsDateFormat: true, prevText: 'MM', nextText: 'MM',
        onSelect: function(d) {
            var i = $.inArray(d, days);

            if (i == -1)
                days.push(d);
            else
                days.splice(i, 1);
        },
        beforeShowDay: function(d) {
            return ([true, $.inArray($.datepicker.formatDate('yymmdd', d), days) == -1 ? 'ui-state-free' : 'ui-state-busy']);
        }
    });
});
</script>

NOTE: You can prefill days with a list of dates like '20190101' with a piece of code in PHP.

Add 2 lines to your CSS:

#calendar .ui-state-busy a {background:#e6e6e6 !important;}
#calendar .ui-state-free a {background:none !important;}

To get the list of days selected by the calendar in a <form>:

<div id="calendar"></div>
<form method="post">
<input type="submit" name="calendar_get" id="calendar_get" value="Validate" />
</form>

Add this to the <script>:

    $('#calendar_get').click(function() {
        $(this).append('<input type="hidden" name="calendar_days" value="' + days.join(',') + '" />');
    });

Apply implode on the string in $_POST['calendar_days'] and map strtotime to all the formatted dates.

Here's a simple JS function to add commas to an integer number in string format. It will handle whole numbers or decimal numbers. You can pass it either a number or a string. It obviously returns a string.

function addCommas(str) {
    var parts = (str + "").split("."),
        main = parts[0],
        len = main.length,
        output = "",
        first = main.charAt(0),
        i;

    if (first === '-') {
        main = main.slice(1);
        len = main.length;    
    } else {
        first = "";
    }
    i = len - 1;
    while(i >= 0) {
        output = main.charAt(i) + output;
        if ((len - i) % 3 === 0 && i > 0) {
            output = "," + output;
        }
        --i;
    }
    // put sign back
    output = first + output;
    // put decimal part back
    if (parts.length > 1) {
        output += "." + parts[1];
    }
    return output;
}

Here's a set of test cases: http://jsfiddle.net/jfriend00/6y57j/

You can see it being used in this previous jsFiddle: http://jsfiddle.net/jfriend00/sMnjT/. You can find functions that will handle decimal numbers too with a simple Google search for "javascript add commas".

Converting a number to a string can be done many ways. The easiest is just to add it to a string:

var myNumber = 3;
var myStr = "" + myNumber;   // "3"

Within, the context of your jsFiddle, you'd get commas into the counter by changing this line:

jTarget.text(current);

to this:

jTarget.text(addCommas(current));

You can see it working here: http://jsfiddle.net/jfriend00/CbjSX/

I had this problem with Django.

Fix it by explicitly setting your hostname to "localhost".

If you define a class without any constructor, the compiler will synthesize a constructor for you (and that will be a default constructor -- i.e., one that doesn't require any arguments). If, however, you do define a constructor, (even if it does take one or more arguments) the compiler will not synthesize a constructor for you -- at that point, you've taken responsibility for constructing objects of that class, so the compiler "steps back", so to speak, and leaves that job to you.

You have two choices. You need to either provide a default constructor, or you need to supply the correct parameter when you define an object. For example, you could change your constructor to look something like:

Blowfish(BlowfishAlgorithm algorithm = CBC);

...so the ctor could be invoked without (explicitly) specifying an algorithm (in which case it would use CBC as the algorithm).

The other alternative would be to explicitly specify the algorithm when you define a Blowfish object:

class GameCryptography { 
    Blowfish blowfish_;
public:
    GameCryptography() : blowfish_(ECB) {}
    // ...
};

In C++ 11 (or later) you have one more option available. You can define your constructor that takes an argument, but then tell the compiler to generate the constructor it would have if you didn't define one:

class GameCryptography { 
public:

    // define our ctor that takes an argument
    GameCryptography(BlofishAlgorithm); 

    // Tell the compiler to do what it would have if we didn't define a ctor:
    GameCryptography() = default;
};

As a final note, I think it's worth mentioning that ECB, CBC, CFB, etc., are modes of operation, not really encryption algorithms themselves. Calling them algorithms won't bother the compiler, but is unreasonably likely to cause a problem for others reading the code.

Little late to the game but i found a way to fix this for me that i had not seen anywhere else. Select your connection from Connection Managers. On the right you should see properties. Check to see if there are any expressions there if not add one. In your package explorer add a variable called connection to sql or whatever. Set the variable as a string and set the value as your connection string and include the User Id and password. Back to the connection manager properties and expression. From the drop down select ConnectionString and set the second box as the name of your variable. It should look like this

I could not for the life of me find another solution but this worked!

Check out the range documentation, you have to define a negative step:

>>> range(10, 0, -1)
[10, 9, 8, 7, 6, 5, 4, 3, 2, 1]

Also worth checking is if there are any errors in the return type of your interface methods. I could reproduce this issue by having an unintended return type like Call<Call<ResponseBody>>

See the reference documentation for the String class: String s = String.valueOf(date);

If your Long might be null and you don't want to get a 4-letter "null" string, you might use Objects.toString, like: String s = Objects.toString(date, null);

EDIT:

You reverse it using Long l = Long.valueOf(s); but in this direction you need to catch NumberFormatException

This might be useful https://docs.djangoproject.com/en/dev/topics/db/queries/#spanning-multi-valued-relationships

Basically it sounds like they act as OR

If you don't want to use a separate JS library to create a custom control for that, you could use two confirm dialogs to do the checks:

if (confirm("Are you sure you want to quit?") ) {
    if (confirm("Save your work before leaving?") ) {
        // code here for save then leave (Yes)
    } else {
        //code here for no save but leave (No)
    }
} else {
    //code here for don't leave (Cancel)
}

I couldn't get it to trigger that on any page. A more robust version of this would do it:

window.console.log = function(){
    console.error('The developer console is temp...');
    window.console.log = function() {
        return false;
    }
}

console.log('test');

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

Javascripts .call() and .apply() methods allow you to set the context for a function.

var myfunc = function(){
    alert(this.name);
};

var obj_a = {
    name:  "FOO"
};

var obj_b = {
    name:  "BAR!!"
};

Now you can call:

myfunc.call(obj_a);

Which would alert FOO. The other way around, passing obj_b would alert BAR!!. The difference between .call() and .apply() is that .call() takes a comma separated list if you're passing arguments to your function and .apply() needs an array.

myfunc.call(obj_a, 1, 2, 3);
myfunc.apply(obj_a, [1, 2, 3]);

Therefore, you can easily write a function hook by using the apply() method. For instance, we want to add a feature to jQuerys .css() method. We can store the original function reference, overwrite the function with custom code and call the stored function.

var _css = $.fn.css;
$.fn.css = function(){
   alert('hooked!');
   _css.apply(this, arguments);
};

Since the magic arguments object is an array like object, we can just pass it to apply(). That way we guarantee, that all parameters are passed through to the original function.

This not the best way to manage session in react you can use web tokens to encrypt your data that you want save,you can use various number of services available a popular one is JSON web tokens(JWT) with web-tokens you can logout after some time if there no action from the client And after creating the token you can store it in your local storage for ease of access.

jwt.sign({user}, 'secretkey', { expiresIn: '30s' }, (err, token) => {
    res.json({
      token
  });

user object in here is the user data which you want to keep in the session

localStorage.setItem('session',JSON.stringify(token));

Quite simple, with a * wildcard.

cp -r Folder1/* Folder2/

But according to your example recursion is not needed so the following will suffice:

cp Folder1/* Folder2/

EDIT:

Or skip the mkdir Folder2 part and just run:

cp -r Folder1 Folder2

It looks OK apart from the space in your ID attribute, which is not valid, and the fact that you're replacing the value of your input before checking the selection.

function textbox()_x000D_
{_x000D_
        var ctl = document.getElementById('Javascript_example');_x000D_
        var startPos = ctl.selectionStart;_x000D_
        var endPos = ctl.selectionEnd;_x000D_
        alert(startPos + ", " + endPos);_x000D_
}

<input id="Javascript_example" name="one" type="text" value="Javascript example" onclick="textbox()">

Also, if you're supporting IE <= 8 you need to be aware that those browsers do not support selectionStart and selectionEnd.

I went through a similar issue. If you consider your "YeagerTechResources.Resources", it means that your Resources.resx is at the root folder of your project.

Be careful to include the full path eg : "project\subfolder(s)\file[.resx]" to the ResourceManager constructor.

Short definition:

grep: search for specific terms in a file

#usage
$ grep This file.txt
Every line containing "This"
Every line containing "This"
Every line containing "This"
Every line containing "This"

$ cat file.txt
Every line containing "This"
Every line containing "This"
Every line containing "That"
Every line containing "This"
Every line containing "This"

Now awk and sed are completly different than grep. awk and sed are text processors. Not only do they have the ability to find what you are looking for in text, they have the ability to remove, add and modify the text as well (and much more).

awk is mostly used for data extraction and reporting. sed is a stream editor
Each one of them has its own functionality and specialties.

Example
Sed

$ sed -i 's/cat/dog/' file.txt
# this will replace any occurrence of the characters 'cat' by 'dog'

Awk

$ awk '{print $2}' file.txt
# this will print the second column of file.txt

Basic awk usage:
Compute sum/average/max/min/etc. what ever you may need.

$ cat file.txt
A 10
B 20
C 60
$ awk 'BEGIN {sum=0; count=0; OFS="\t"} {sum+=$2; count++} END {print "Average:", sum/count}' file.txt
Average:    30

I recommend that you read this book: Sed & Awk: 2nd Ed.

It will help you become a proficient sed/awk user on any unix-like environment.

function hex2a(hexx) {
    var hex = hexx.toString();//force conversion
    var str = '';
    for (var i = 0; (i < hex.length && hex.substr(i, 2) !== '00'); i += 2)
        str += String.fromCharCode(parseInt(hex.substr(i, 2), 16));
    return str;
}
hex2a('32343630'); // returns '2460'

This is because you are reading a cursor, not an array. This means that you are reading sequentially through the results and when you get to the end you would need to reset the cursor to the beginning of the results to read them again.

If you did want to read over the results multiple times, you could use fetchAll to read the results into a true array and then it would work as you are expecting.

In .NET 4.0, you can use the Task Parallel Library.

In earlier versions, you can create a list of Thread objects in a loop, calling Start on each one, and then make another loop and call Join on each one.

Or you can simply do:

referenceNode.parentNode.insertBefore( newNode, referenceNode )
referenceNode.parentNode.insertBefore( referenceNode, newNode )

any():

if any(t < 0 for t in x):
    # do something

Also, if you're going to use "True in ...", make it a generator expression so it doesn't take O(n) memory:

if True in (t < 0 for t in x):

GitHub Pages is GitHub’s official solution to this problem.

raw.githubusercontent makes all files use the text/plain MIME type, even if the file is a CSS or JavaScript file. So going to https://raw.githubusercontent.com/‹user›/‹repo›/‹branch›/‹filepath› will not be the correct MIME type but instead a plaintext file, and linking it via <link href="..."/> or <script src="..."></script> won’t work—the CSS won’t apply / the JS won’t run.

GitHub Pages hosts your repo at a special URL, so all you have to do is check-in your files and push. Note that in most cases, GitHub Pages requires you to commit to a special branch, gh-pages.

On your new site, which is usually https://‹user›.github.io/‹repo›, every file committed to the gh-pages branch (the most recent commit) is present at this url. So then you can link to your js file via <script src="https://‹user›.github.io/‹repo›/file.js"></script>, and this will be the correct MIME type.

Do you have build files?

Personally, my recommendation is to run this branch parallel to master. On the gh-pages branch, you can edit your .gitignore file to check in all the dist/build files you need for your site (e.g. if you have any minified/compiled files), while keeping them ignored on your master branch. This is useful because you typically don’t want to track changes in build files in your regular repo. Every time you want to update your hosted files, simply merge master into gh-pages, rebuild, commit, and then push.

(protip: you can merge and rebuild in the same commit with these steps:)

$ git checkout gh-pages
$ git merge --no-ff --no-commit master  # prepare the merge but don’t commit it (as if there were a merge conflict)
$ npm run build                         # (or whatever your build process is)
$ git add .                             # stage the newly built files
$ git merge --continue                  # commit the merge
$ git push origin gh-pages

to get the fqdn corresponding to the first IpAddress, it took this command:

PS C:\Windows\system32> [System.Net.Dns]::GetHostByAddress([System.Net.Dns]::GetHostByName($env:computerName).AddressList[0]).HostName
WIN-1234567890.fritz.box

where [System.Net.Dns]::GetHostByName($env:computerName).AddressList[0] represents the first IpAddress-Object and [System.Net.Dns]::GetHostByAddress gets the dns-object out of it.

If I took the winning solution on my standalone Windows, I got only:

PS C:\Windows\system32> (Get-WmiObject win32_computersystem).DNSHostName+"."+(Get-WmiObject win32_computersystem).Domain
WIN-1234567890.WORKGROUP

that's not what I wanted.

As other answers have noted, assert is similar to throwing an exception if a given condition isn't true. An important difference is that assert statements get ignored if you compile your code with the optimization option -O. The documentation says that assert expression can better be described as being equivalent to

if __debug__:
   if not expression: raise AssertionError

This can be useful if you want to thoroughly test your code, then release an optimized version when you're happy that none of your assertion cases fail - when optimization is on, the __debug__ variable becomes False and the conditions will stop getting evaluated. This feature can also catch you out if you're relying on the asserts and don't realize they've disappeared.

As static variables are class level variables, they will store " permanent generation " of heap memory. Please look into this for more details of JVM. Hoping this will be helpful

Whereas every class starting with "your-class-name" uses this style.

So in your case, you could do it like so:

[class^="class"]{
  display: inline-block;
  //some other properties
  &:hover{
   color: darken(#FFFFFF, 10%);
 }  
}

.class-b{
  //specifically for class b
  width: 100px;
  &:hover{
     color: darken(#FFFFFF, 20%);
  }
}

How about:

def ExtractAlphanumeric(InputString):
    from string import ascii_letters, digits
    return "".join([ch for ch in InputString if ch in (ascii_letters + digits)])

This works by using list comprehension to produce a list of the characters in InputString if they are present in the combined ascii_letters and digits strings. It then joins the list together into a string.

I recommend that you get in the habit, right now, of using ANSI-style joins, meaning you should use the INNER JOIN, LEFT OUTER JOIN, RIGHT OUTER JOIN, FULL OUTER JOIN, and CROSS JOIN elements in your SQL statements rather than using the "old-style" joins where all the tables are named together in the FROM clause and all the join conditions are put in the the WHERE clause. ANSI-style joins are easier to understand and less likely to be miswritten and/or misinterpreted than "old-style" joins.

I'd rewrite your query as:

SELECT bc.firstname,
       bc.lastname,
       b.title,
       TO_CHAR(bo.orderdate, 'MM/DD/YYYY') "Order Date",
       p.publishername
FROM BOOK_CUSTOMER bc
INNER JOIN books b
  ON b.BOOK_ID = bc.BOOK_ID
INNER JOIN  book_order bo
  ON bo.BOOK_ID = b.BOOK_ID
INNER JOIN publisher p
  ON p.PUBLISHER_ID = b.PUBLISHER_ID
WHERE p.publishername = 'PRINTING IS US';

Well, if you are writing to a CSV file, then why do you use space as a delimiter? CSV files use commas or semicolons (in Excel) as cell delimiters, so if you use delimiter=' ', you are not really producing a CSV file. You should simply construct csv.writer with the default delimiter and dialect. If you want to read the CSV file later into Excel, you could specify the Excel dialect explicitly just to make your intention clear (although this dialect is the default anyway):

example = csv.writer(open("test.csv", "wb"), dialect="excel")

Seems that new browsers support most of the tags: <header>, <section> etc. For older browsers (IE, Fx2, Camino etc) then you can use this to allow styling of these tags:

document.createElement('header');

Would make these older browsers allow CSS styling of a header tag, instead of just ignoring it.

This means that you can now use the new tags without any loss of functionality, which is a good start!

I've found another solution (it must be more efficient than "string witchcraft" workarounds):

>>> import decimal
# By default rounding setting in python is decimal.ROUND_HALF_EVEN
>>> decimal.getcontext().rounding = decimal.ROUND_DOWN
>>> c = decimal.Decimal(34.1499123)
# By default it should return 34.15 due to '99' after '34.14'
>>> round(c,2)
Decimal('34.14')
>>> float(round(c,2))
34.14
>>> print(round(c,2))
34.14

Just get the millisecond timestamp and add 20 minutes to it:

twentyMinutesLater = new Date(currentDate.getTime() + (20*60*1000))

You can increase client_max_body_size and upload_max_filesize + post_max_size all day long. Without adjusting HTTP timeout it will never work.

//You need to adjust this, and probably on PHP side also. client_body_timeout 2min // 1GB fileupload

Use dir() to find out if the module has a __version__ attribute at all.

>>> import selenium
>>> dir(selenium)
['__builtins__', '__doc__', '__file__', '__name__',
 '__package__', '__path__', '__version__']
>>> selenium.__version__
'3.141.0'
>>> selenium.__path__
['/venv/local/lib/python2.7/site-packages/selenium']

Have them try to write a program that can evaluate arbitrary simple arithmetic expressions. This is a simple problem to understand but as you start getting deeper into it a lot of basic parsing starts to make sense.

Well presumably it's not using the same version of Java when running it externally. Look through the startup scripts carefully to find where it picks up the version of Java to run. You should also check the startup logs to see whether they indicate which version is running.

Alternatively, unless you need the Java 7 features, you could always change your compiler preferences in Eclipse to target 1.6 instead.

Note: Test your case, see comments.

Here's a sample which is more efficient on long strings with many small replacements.

source = "Here is foo, it does moo!"

replacements = {
    'is': 'was', # replace 'is' with 'was'
    'does': 'did',
    '!': '?'
}

def replace(source, replacements):
    finder = re.compile("|".join(re.escape(k) for k in replacements.keys())) # matches every string we want replaced
    result = []
    pos = 0
    while True:
        match = finder.search(source, pos)
        if match:
            # cut off the part up until match
            result.append(source[pos : match.start()])
            # cut off the matched part and replace it in place
            result.append(replacements[source[match.start() : match.end()]])
            pos = match.end()
        else:
            # the rest after the last match
            result.append(source[pos:])
            break
    return "".join(result)

print replace(source, replacements)

The point is in avoiding many concatenations of long strings. We chop the source string to fragments, replacing some of the fragments as we form the list, and then join the whole thing back into a string.

from itertools import groupby
[ key for key,_ in groupby(sortedList)]

The list doesn't even have to be sorted, the sufficient condition is that equal values are grouped together.

Edit: I assumed that "preserving order" implies that the list is actually ordered. If this is not the case, then the solution from MizardX is the right one.

Community edit: This is however the most elegant way to "compress duplicate consecutive elements into a single element".

To add new ViewController once you have have an existing ViewController, follow below step:

1. Click on background of Main.storyboard.

2. Search and select ViewController from object library at the utility window.

3. Drag and drop it in background to create a new ViewController.

Solved my own problem. This line:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));

needs to be:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"));

or since Java 7:

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));

Get the .column parent of the this element, get its previous sibling, then find any input there:

$(this).closest(".column").prev().find("input:first").val();

It looks like github has a simple UI for creating branches. I opened the branch drop-down and it prompts me to "Find or create a branch ...". Type the name of your new branch, then click the "create" button that appears.

To retrieve your new branch from github, use the standard git fetch command.

I'm not sure this will help your underlying problem, though, since the underlying data being pushed to the server (the commit objects) is the same no matter what branch it's being pushed to.

The context menu shown above is accessible by right clicking / presssing & holding the "reload" button, while Chrome Dev Tools is opened.

Empty cache and hard reload works best for me.

Another Advantage: This option keeps all other opened tabs and website data untouched. It only reloads and clears the current page.

need order

NSArray *yourarray = @[@"a",@"b",@"c"];
NSOrderedSet *orderedSet = [NSOrderedSet orderedSetWithArray:yourarray];
NSArray *arrayWithoutDuplicates = [orderedSet array];
NSLog(@"%@",arrayWithoutDuplicates);

or don't need order

NSSet *set = [NSSet setWithArray:yourarray];
NSArray *arrayWithoutOrder = [set allObjects];
NSLog(@"%@",arrayWithoutOrder);

I would give the requests library a try for this. Essentially just a much easier to use wrapper around the standard library modules (i.e. urllib2, httplib2, etc.) you would use for the same thing. For example, to fetch json data from a url that requires basic authentication would look like this:

import requests

response = requests.get('http://thedataishere.com',
                         auth=('user', 'password'))
data = response.json()

For kerberos authentication the requests project has the reqests-kerberos library which provides a kerberos authentication class that you can use with requests:

import requests
from requests_kerberos import HTTPKerberosAuth

response = requests.get('http://thedataishere.com',
                         auth=HTTPKerberosAuth())
data = response.json()

Have created a simple dictionary in JS here:

function JSdict() {
    this.Keys = [];
    this.Values = [];
}

// Check if dictionary extensions aren't implemented yet.
// Returns value of a key
if (!JSdict.prototype.getVal) {
    JSdict.prototype.getVal = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        for (var i = 0; i < this.Keys.length; i++) {
            if (this.Keys[i] == key) {
                return this.Values[i];
            }
        }
        return "Key not found!";
    }
}


// Check if dictionary extensions aren't implemented yet.
// Updates value of a key
if (!JSdict.prototype.update) {
    JSdict.prototype.update = function (key, val) {
        if (key == null || val == null) {
            return "Key or Value cannot be null";
        }
        // Verify dict integrity before each operation
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Values[i] = val;
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}



// Check if dictionary extensions aren't implemented yet.
// Adds a unique key value pair
if (!JSdict.prototype.add) {
    JSdict.prototype.add = function (key, val) {
        // Allow only strings or numbers as keys
        if (typeof (key) == "number" || typeof (key) == "string") {
            if (key == null || val == null) {
                return "Key or Value cannot be null";
            }
            if (keysLength != valsLength) {
                return "Dictionary inconsistent. Keys length don't match values!";
            }
            var keysLength = this.Keys.length;
            var valsLength = this.Values.length;
            for (var i = 0; i < keysLength; i++) {
                if (this.Keys[i] == key) {
                    return "Duplicate keys not allowed!";
                }
            }
            this.Keys.push(key);
            this.Values.push(val);
        }
        else {
            return "Only number or string can be key!";
        }
    }
}

// Check if dictionary extensions aren't implemented yet.
// Removes a key value pair
if (!JSdict.prototype.remove) {
    JSdict.prototype.remove = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Keys.shift(key);
                this.Values.shift(this.Values[i]);
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}

The above implementation can now be used to simulate a dictionary as:

var dict = new JSdict();

dict.add(1, "one")

dict.add(1, "one more")
"Duplicate keys not allowed!"

dict.getVal(1)
"one"

dict.update(1, "onne")

dict.getVal(1)
"onne"

dict.remove(1)

dict.getVal(1)
"Key not found!"

This is just a basic simulation. It can be further optimized by implementing a better running time algorithm to work in atleast O(nlogn) time complexity or even less. Like merge/quick sort on arrays and then some B-search for lookups. I Didn't give a try or searched about mapping a hash function in JS.

Also, Key and Value for the JSdict obj can be turned into private variables to be sneaky.

Hope this helps!

EDIT >> After implementing the above, I personally used the JS objects as associative arrays that are available out-of-the-box.

However, I would like to make a special mention about two methods that actually proved helpful to make it a convenient hashtable experience.

Viz: dict.hasOwnProperty(key) and delete dict[key]

Another mean to repeat an arbitrary string n times:

Pros:

• Works with POSIX shell.
• Output can be assigned to a variable.
• Repeats any string.
• Very fast even with very large repeats.

Cons:

• Requires Gnu Core Utils's yes command.

#!/usr/bin/sh
to_repeat='='
repeat_count=80
yes "$to_repeat" | tr -d '\n' | head -c "$repeat_count"

With an ANSI terminal and US-ASCII characters to repeat. You can use an ANSI CSI escape sequence. It is the fastest way to repeat a character.

#!/usr/bin/env bash

char='='
repeat_count=80
printf '%c\e[%db' "$char" "$repeat_count"

Or statically:

Print a line of 80 times =:

printf '=\e[80b\n'

Limitations:

• Not all terminals understands the repeat_char ANSI CSI sequence.
• Only US-ASCII or single-byte ISO characters can be repeated.
• Repeat stops at last column, so you can use a large value to fill a whole line regardless of terminal width.
• The repeat is only for display. Capturing output into a shell variable will not expand the repeat_char ANSI CSI sequence into the repeated character.

I've used MongoDB extensively (for the past 6 months), building a hierarchical data management system, and I can vouch for both the ease of setup (install it, run it, use it!) and the speed. As long as you think about indexes carefully, it can absolutely scream along, speed-wise.

I gather that Cassandra, due to its use with large-scale projects like Twitter, has better scaling functionality, although the MongoDB team is working on parity there. I should point out that I've not used Cassandra beyond the trial-run stage, so I can't speak for the detail.

The real swinger for me, when we were assessing NoSQL databases, was the querying - Cassandra is basically just a giant key/value store, and querying is a bit fiddly (at least compared to MongoDB), so for performance you'd have to duplicate quite a lot of data as a sort of manual index. MongoDB, on the other hand, uses a "query by example" model.

For example, say you've got a Collection (MongoDB parlance for the equivalent to a RDMS table) containing Users. MongoDB stores records as Documents, which are basically binary JSON objects. e.g:

{
   FirstName: "John",
   LastName: "Smith",
   Email: "[email protected]",
   Groups: ["Admin", "User", "SuperUser"]
}

If you wanted to find all of the users called Smith who have Admin rights, you'd just create a new document (at the admin console using Javascript, or in production using the language of your choice):

{
   LastName: "Smith",
   Groups: "Admin"
}

...and then run the query. That's it. There are added operators for comparisons, RegEx filtering etc, but it's all pretty simple, and the Wiki-based documentation is pretty good.

There is one caveat to the key/value loop that Ian mentioned. If it is possible that the Objects may have attributes attached to their Prototype, and when you use the in operator, these attributes will be included. So you will want to make sure that the key is an attribute of your instance, and not of the prototype. Older IEs are known for having indexof(v) show up as a key.

I suggest something like this

def testFunc( **kwargs ):
    options = {
            'option1' : 'default_value1',
            'option2' : 'default_value2',
            'option3' : 'default_value3', }

    options.update(kwargs)
    print options

testFunc( option1='new_value1', option3='new_value3' )
# {'option2': 'default_value2', 'option3': 'new_value3', 'option1': 'new_value1'}

testFunc( option2='new_value2' )
# {'option1': 'default_value1', 'option3': 'default_value3', 'option2': 'new_value2'}

And then use the values any way you want

dictionaryA.update(dictionaryB) adds the contents of dictionaryB to dictionaryA overwriting any duplicate keys.

If you just need to make simple get requests and don't need support for any other HTTP methods take a look at: simple-get:

var get = require('simple-get');

get('http://example.com', function (err, res) {
  if (err) throw err;
  console.log(res.statusCode); // 200
  res.pipe(process.stdout); // `res` is a stream
});

Looking at the implementation differences, I see that:

MDC on encodeURIComponent():

• literal characters (regex representation): [-a-zA-Z0-9._*~'()!]

Java 1.5.0 documentation on URLEncoder:

• literal characters (regex representation): [-a-zA-Z0-9._*]
• the space character " " is converted into a plus sign "+".

So basically, to get the desired result, use URLEncoder.encode(s, "UTF-8") and then do some post-processing:

• replace all occurrences of "+" with "%20"
• replace all occurrences of "%xx" representing any of [~'()!] back to their literal counter-parts

Try hooking into the CellContentClick event. The DataGridViewCellEventArgs will have a ColumnIndex and a RowIndex so you can know if a ChecboxCell was in fact clicked. The good thing about this event is that it will only fire if the actual checkbox itself was clicked. If you click on the white area of the cell around the checkbox, it won't fire. This way, you're pretty much guaranteed that the checkbox value was changed when this event fires. You can then call Invalidate() to trigger your drawing event, as well as a call to EndEdit() to trigger the end of the row's editing if you need that.

to load a KeyStore, you'll need to tell it the type of keystore it is (probably jceks), provide an inputstream, and a password. then, you can load it like so:

KeyStore ks  = KeyStore.getInstance(TYPE_OF_KEYSTORE);
ks.load(new FileInputStream(PATH_TO_KEYSTORE), PASSWORD);

this can throw a KeyStoreException, so you can surround in a try block if you like, or re-throw. Keep in mind a keystore can contain multiple keys, so you'll need to look up your key with an alias, here's an example with a symmetric key:

SecretKeyEntry entry = (KeyStore.SecretKeyEntry)ks.getEntry(SOME_ALIAS,new KeyStore.PasswordProtection(SOME_PASSWORD));
SecretKey someKey = entry.getSecretKey();

Also worth noting window.scrollBy(dx,dy) (ref)

You can also do this in phpMyAdmin without writing SQL.

• Click on a database name in the left column.
• Click on a table name in the left column.
• Click the "Operations" tab at the top.
• Under "Table options" there should be a field for AUTO_INCREMENT (only on tables that have an auto-increment field).
• Input desired value and click the "Go" button below.

Note: You'll see that phpMyAdmin is issuing the same SQL that is mentioned in the other answers.

The existing answers are now outdated. The native getBoundingClientRect() method has been around for quite a while now, and does exactly what the question asks for. Plus it is supported across all browsers (including IE 5, it seems!)

From MDN page:

The returned value is a TextRectangle object, which contains read-only left, top, right and bottom properties describing the border-box, in pixels, with the top-left relative to the top-left of the viewport.

You use it like so:

var viewportOffset = el.getBoundingClientRect();
// these are relative to the viewport, i.e. the window
var top = viewportOffset.top;
var left = viewportOffset.left;

I just did some tests of the four options that I know about.

Measure-Command {$(1..1000) | Out-Null}

TotalMilliseconds : 76.211

Measure-Command {[Void]$(1..1000)}

TotalMilliseconds : 0.217

Measure-Command {$(1..1000) > $null}

TotalMilliseconds : 0.2478

Measure-Command {$null = $(1..1000)}

TotalMilliseconds : 0.2122

## Control, times vary from 0.21 to 0.24
Measure-Command {$(1..1000)}

TotalMilliseconds : 0.2141

So I would suggest that you use anything but Out-Null due to overhead. The next important thing, to me, would be readability. I kind of like redirecting to $null and setting equal to $null myself. I use to prefer casting to [Void], but that may not be as understandable when glancing at code or for new users.

I guess I slightly prefer redirecting output to $null.

Do-Something > $null

Edit

After stej's comment again, I decided to do some more tests with pipelines to better isolate the overhead of trashing the output.

Here are some tests with a simple 1000 object pipeline.

## Control Pipeline
Measure-Command {$(1..1000) | ?{$_ -is [int]}}

TotalMilliseconds : 119.3823

## Out-Null
Measure-Command {$(1..1000) | ?{$_ -is [int]} | Out-Null}

TotalMilliseconds : 190.2193

## Redirect to $null
Measure-Command {$(1..1000) | ?{$_ -is [int]} > $null}

TotalMilliseconds : 119.7923

In this case, Out-Null has about a 60% overhead and > $null has about a 0.3% overhead.

Addendum 2017-10-16: I originally overlooked another option with Out-Null, the use of the -inputObject parameter. Using this the overhead seems to disappear, however the syntax is different:

Out-Null -inputObject ($(1..1000) | ?{$_ -is [int]})

And now for some tests with a simple 100 object pipeline.

## Control Pipeline
Measure-Command {$(1..100) | ?{$_ -is [int]}}

TotalMilliseconds : 12.3566

## Out-Null
Measure-Command {$(1..100) | ?{$_ -is [int]} | Out-Null}

TotalMilliseconds : 19.7357

## Redirect to $null
Measure-Command {$(1..1000) | ?{$_ -is [int]} > $null}

TotalMilliseconds : 12.8527

Here again Out-Null has about a 60% overhead. While > $null has an overhead of about 4%. The numbers here varied a bit from test to test (I ran each about 5 times and picked the middle ground). But I think it shows a clear reason to not use Out-Null.

The reason you shouldn't use new Array is demonstrated by this code:

var Array = function () {};

var x = new Array(4);

alert(x.length);  // undefined...

Some other code could mess with the Array variable. I know it's a bit far fetched that anyone would write such code, but still...

Also, as Felix King said, the interface is a little inconsistent, and could lead to some very difficult-to-track-down bugs.

If you wanted an array with length = x, filled with undefined (as new Array(x) would do), you could do this:

var x = 4;
var myArray = [];
myArray[x - 1] = undefined;

alert(myArray.length); // 4

You have to do bulk insert with format file:

   BULK INSERT Employee FROM 'path\tempFile.csv ' 
   WITH (FORMATFILE = 'path\tempFile.fmt');

where format file (tempFile.fmt) looks like this:

11.0
2
1 SQLCHAR 0 50 "\t"  2  Name   SQL_Latin1_General_CP1_CI_AS
2 SQLCHAR 0 50 "\r\n" 3  Address  SQL_Latin1_General_CP1_CI_AS

I had the very same issue running Jupyter. After chasing my tail on permissions, I found that everything cleared up after I changed ownership on the directory where I was trying to run/store my notebooks. Ex.: I was running my files out of my ~/bash dir. That was root:root; when I changed it to jim:jim....no more errors.

You can mix git blame and git log commands to retrieve the summary of each commit in the git blame command and append them. Something like the following bash + awk script. It appends the commit summary as code comment inline.

git blame FILE_NAME | awk -F" " \
'{
   commit = substr($0, 0, 8);
   if (!a[commit]) {
     query = "git log --oneline -n 1 " commit " --";
     (query | getline a[commit]);
   }
   print $0 "  // " substr(a[commit], 9);
 }'

In one line:

git blame FILE_NAME | awk -F" " '{ commit = substr($0, 0, 8); if (!a[commit]) { query = "git log --oneline -n 1 " commit " --"; (query | getline a[commit]); } print $0 "  // " substr(a[commit], 9); }'

It is a library from SSL. You need to install openssl.

You might also meet missing readline() function in python. You have to install pyreadline Lib.

(function(){
    var i = 0;
    function stop(){
        clearTimeout(i);
    }

    function start(){
        i = setTimeout( timed, 1000 );
    }

    function timed(){
       document.getElementById("input").value++;
       start();
    }

    window.stop = stop;
    window.start = start;
})()

Clone the repository as normal:

git clone git://github.com/rspec/rspec-tmbundle.git RSpec.tmbundle

Then checkout the tag you want like so:

git checkout tags/1.1.4

This will checkout out the tag in a 'detached HEAD' state. In this state, "you can look around, make experimental changes and commit them, and [discard those commits] without impacting any branches by performing another checkout".

To retain any changes made, move them to a new branch:

git checkout -b 1.1.4-jspooner

You can get back to the master branch by using:

git checkout master

Note, as was mentioned in the first revision of this answer, there is another way to checkout a tag:

git checkout 1.1.4

But as was mentioned in a comment, if you have a branch by that same name, this will result in git warning you that the refname is ambiguous and checking out the branch by default:

warning: refname 'test' is ambiguous.
Switched to branch '1.1.4'

The shorthand can be safely used if the repository does not share names between branches and tags.

Use Collections.swap and Arrays.asList:

Collections.swap(Arrays.asList(arr), i, j);

<!doctype html>_x000D_
<html lang="en">_x000D_

<script type="application/javascript" >_x000D_
    lfckv = document.getElementsByClassName("lifecheck");_x000D_
    if (true === lfckv[0].checked) {_x000D_
      alert('the checkbox is checked');_x000D_
    }_x000D_
</script>_x000D_
</body>_x000D_
</html>

so after you can add event in javascript to have dynamical event affected with the checkbox .

My rule is simple. If you are using C++ prefer C++ libraries and not C :)

This is with reference to @Ladislav Mrnka's answer on using fluent api for configuring one-to-one relationship.

Had a situation where having FK of dependent must be it's PK was not feasible.

E.g., Foo already has one-to-many relationship with Bar.

public class Foo {
   public Guid FooId;
   public virtual ICollection<> Bars; 
}
public class Bar {
   //PK
   public Guid BarId;
   //FK to Foo
   public Guid FooId;
   public virtual Foo Foo;
}

Now, we had to add another one-to-one relationship between Foo and Bar.

public class Foo {
   public Guid FooId;
   public Guid PrimaryBarId;// needs to be removed(from entity),as we specify it in fluent api
   public virtual Bar PrimaryBar;
   public virtual ICollection<> Bars;
}
public class Bar {
   public Guid BarId;
   public Guid FooId;
   public virtual Foo PrimaryBarOfFoo;
   public virtual Foo Foo;
}

Here is how to specify one-to-one relationship using fluent api:

modelBuilder.Entity<Bar>()
            .HasOptional(p => p.PrimaryBarOfFoo)
            .WithOptionalPrincipal(o => o.PrimaryBar)
            .Map(x => x.MapKey("PrimaryBarId"));

Note that while adding PrimaryBarId needs to be removed, as we specifying it through fluent api.

Also note that method name [WithOptionalPrincipal()][1] is kind of ironic. In this case, Principal is Bar. WithOptionalDependent() description on msdn makes it more clear.

If you need to support more than one format you will have to pattern match your input and parse accordingly.

final DateFormat fmt;
if (dateString.endsWith("Z")) {
    fmt = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
} else {
    fmt = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
}

I'd guess you're dealing with a bug in the API you're using which has quoted the Z timezone date pattern somewhere...

I use an enum with no instances

public enum MyUtils { 
    ; // no instances
    // class is final and the constructor is private

    public static int myUtilityMethod(int x) {
        return x * x;
    }
}

you can call this using

int y = MyUtils.myUtilityMethod(5); // returns 25.

I was getting this problem with a maven project using the eclipse IDE. I changed the 'Order and Export' in the project's build path putting the Maven dependencies first and the error disappeared. I guess it's because the eclipse IDE was initially building my application source before loading the Maven libraries.

If the 2nd company is happy for you to access their content in an IFrame then they need to take the restriction off - they can do this fairly easily in the IIS config.

There's nothing you can do to circumvent it and anything that does work should get patched quickly in a security hotfix. You can't tell the browser to just render the frame if the source content header says not allowed in frames. That would make it easier for session hijacking.

If the content is GET only you don't post data back then you could get the page server side and proxy the content without the header, but then any post back should get invalidated.

As it appears you have the values as text, and not the numeric True/False, then you can use either COUNTIF or SUMPRODUCT

=IF(SUMPRODUCT(--(A2:D2="False")),"False","True")
=IF(COUNTIF(A3:D3,"False*"),"False","True")

The bootstrap 4.0.0 file you are getting from cdn doesn't have a pull-right (or pull-left) class. The v4 is in alpha, so there are many issues like that.

There are 2 options:

1) Reverse to bootstrap 3.3.7

2) Write your own CSS.

you can use this too

.parent:hover * {
   /* ... */
}

height: 100% gives the element 100% height of its parent container.

height: auto means the element height will depend upon the height of its children.

Consider these examples:

height: 100%

<div style="height: 50px">
    <div id="innerDiv" style="height: 100%">
    </div>
</div>

#innerDiv is going to have height: 50px

height: auto

<div style="height: 50px">
    <div id="innerDiv" style="height: auto">
          <div id="evenInner" style="height: 10px">
          </div>
    </div>
</div>

#innerDiv is going to have height: 10px

Css is going to work in same manner i assume.

You can center the content with something like this :

.center{
     text-align:center;
}

Update

To adjust the width in proper manner, modify your DOM as below :

<div class="item-input-inset">
    <label class="item-input-wrapper"> Date
        <input type="text" placeholder="Text Area" />
    </label>
</div>
<div class="item-input-inset">
    <label class="item-input-wrapper"> Suburb
        <input type="text" placeholder="Text Area" />
    </label>
</div>

CSS

label {
    display:inline-block;
    border:1px solid red;
    width:100%;
    font-weight:bold;
}

input{
    float:right; /* shift to right for alignment*/
    width:80% /* set a width, you can use max-width to limit this as well*/
}

Demo

final update

If you don't plan to modify existing HTML (one in your question originally), below css would make me your best friend!! :)

html, body, .con {
    height:100%;
    margin:0;
    padding:0;
}
.item-input-inset {
    display:inline-block;
    width:100%;
    font-weight:bold;
}
.item-input-inset > h4 {
    float:left;
    margin-top:0;/* important alignment */
    width:15%;
}
.item-input-wrapper {
    display:block;
    float:right;
    width:85%;
}
input {
    width:100%;
}

Demo

API level is basically the Android version. Instead of using the Android version name (eg 2.0, 2.3, 3.0, etc) an integer number is used. This number is increased with each version. Android 1.6 is API Level 4, Android 2.0 is API Level 5, Android 2.0.1 is API Level 6, and so on.

Based on an Aptana Studio support response, it was confirmed that the Aptana plugin and Android Development Tools collide on this port (i.e. Aptana's Comet server overlapped on this port). Aptana opened a ticket back in 2010.

Unfortunately, it does not appear that Aptana has fixed it yet or made their Comet server port configurable. Changing the port number in eclipse and restarting adb did NOT fix it for me. I finally was forced to uninstall the Aptana plugin.

1) Yes, a select with NOLOCK will complete faster than a normal select.

2) Yes, a select with NOLOCK will allow other queries against the effected table to complete faster than a normal select.

Why would this be?

NOLOCK typically (depending on your DB engine) means give me your data, and I don't care what state it is in, and don't bother holding it still while you read from it. It is all at once faster, less resource-intensive, and very very dangerous.

You should be warned to never do an update from or perform anything system critical, or where absolute correctness is required using data that originated from a NOLOCK read. It is absolutely possible that this data contains rows that were deleted during the query's run or that have been deleted in other sessions that have yet to be finalized. It is possible that this data includes rows that have been partially updated. It is possible that this data contains records that violate foreign key constraints. It is possible that this data excludes rows that have been added to the table but have yet to be committed.

You really have no way to know what the state of the data is.

If you're trying to get things like a Row Count or other summary data where some margin of error is acceptable, then NOLOCK is a good way to boost performance for these queries and avoid having them negatively impact database performance.

Always use the NOLOCK hint with great caution and treat any data it returns suspiciously.

You could make the element containing the bg text have a lower stacking order ( z-index, position ) and possibly even set opacity. So the element you need on top would need a higher stacking order ( z-index:5; position:relative; for ex ) and the element behind would need something lower ( default or just a lower z-index like 3 and position:relative; ).

You have a couple of options:

• You can add the path to the DLLs to the Executable files settings under Tools > Options > Projects and Solutions > VC++ Directories (but only for building, for executing or debugging here)
• You can add them in your global PATH environment variable
• You can start Visual Studio using a batch file as I described here and manipulate the path in that one
• You can copy the DLLs into the executable file's directory :-)

I fixed this problem by increasing the amount of memory available to the vagrant VM where the database was located.

If you prefer a graphical user interface, you can use pgAdmin III (Linux/Windows/OS X). Simply right click on the table of your choice, then "backup". It will create a pg_dump command for you.

Here you have few solutions ;)

The Location property has type Point which is a struct.

Instead of trying to modify the existing Point, try assigning a new Point object:

 this.balancePanel.Location = new Point(
     this.optionsPanel.Location.X,
     this.balancePanel.Location.Y
 );

This error can also be caused by a javascript line like this one:

navi_elements.style.bottom = 20px;

Notice that the value is not a string.

In this thread, There are so many solutions that work fine if cell takes full screen but they use collection view bounds and midpoints of Visible rect However there is a simple solution to this problem

    DispatchQueue.main.async {
        let visibleCell = self.collImages.visibleCells.first
        print(self.collImages.indexPath(for: visibleCell))
    }

by this, you can get indexPath of the visible cell. I have added DispatchQueue because when you swipe faster and if for a brief moment the next cell is shown then without dispactchQueue you'll get indexPath of briefly shown cell not the cell that is being displayed on the screen.

Using jQuery Mask Plugin there is two possible ways to implement it:

1- Following Anatel's recomendations: https://gist.github.com/3724610/5003f97804ea1e62a3182e21c3b0d3ae3b657dd9

2- Or without following Anatel's recomendations: https://gist.github.com/igorescobar/5327820

All examples above was coded using jQuery Mask Plugin and it can be downloaded at: http://igorescobar.github.io/jQuery-Mask-Plugin/

.NET 4 has two new properties in the Environment class, Is64BitProcess and Is64BitOperatingSystem. Interestingly, if you use Reflector you can see they are implemented differently in the 32-bit & 64-bit versions of mscorlib. The 32-bit version returns false for Is64BitProcess and calls IsWow64Process via P/Invoke for Is64BitOperatingSystem. The 64-bit version just returns true for both.

If the XAMPP server is running for the moment, stop XAMPP server.

Follow these steps to change the port number.

Open the file in following location.

[XAMPP Installation Folder]/apache/conf/httpd.conf

Open the httpd.conf file and search for the String:

Listen 80

This is the port number used by XAMMP.

Then search for the string ServerName and update the Port Number which you entered earlier for Listen

Now save and re-start XAMPP server.

For those of you using SCSS and the NPM package, here is my solution:

npm i --save @fortawesome/fontawesome-free

Then at the top of an SCSS file (ideally an SCSS file imported at the root of your application):

@import '@fortawesome/fontawesome-free/css/fontawesome.css';
@import '@fortawesome/fontawesome-free/css/all.css';

I am not sure if I fully understand your problem but since I had similar issue recently I will try to help you out.

Vendor bundle.

You should use CommonsChunkPlugin for that. in the configuration you specify the name of the chunk (e.g. vendor), and file name that will be generated (vendor.js).

new webpack.optimize.CommonsChunkPlugin("vendor", "vendor.js", Infinity),

Now important part, you have to now specify what does it mean vendor library and you do that in an entry section. One one more item to entry list with the same name as the name of the newly declared chunk (i.e. 'vendor' in this case). The value of that entry should be the list of all the modules that you want to move to vendor bundle. in your case it should look something like:

entry: {
    app: 'entry.js',
    vendor: ['jquery', 'jquery.plugin1']
}

JQuery as global

Had the same problem and solved it with ProvidePlugin. here you are not defining global object but kind of shurtcuts to modules. i.e. you can configure it like that:

new webpack.ProvidePlugin({
    $: "jquery"
})

And now you can just use $ anywhere in your code - webpack will automatically convert that to

require('jquery')

I hope it helped. you can also look at my webpack configuration file that is here

I love webpack, but I agree that the documentation is not the nicest one in the world... but hey.. people were saying same thing about Angular documentation in the begining :)

Edit:

To have entrypoint-specific vendor chunks just use CommonsChunkPlugins multiple times:

new webpack.optimize.CommonsChunkPlugin("vendor-page1", "vendor-page1.js", Infinity),
new webpack.optimize.CommonsChunkPlugin("vendor-page2", "vendor-page2.js", Infinity),

and then declare different extenral libraries for different files:

entry: {
    page1: ['entry.js'],
    page2: ['entry2.js'],
    "vendor-page1": [
        'lodash'
    ],
    "vendor-page2": [
        'jquery'
    ]
},

If some libraries are overlapping (and for most of them) between entry points then you can extract them to common file using same plugin just with different configuration. See this example.

Use anchor links and the scroll-behavior property (MDN reference) for the scrolling container:

scroll-behavior: smooth;

Browser support: Firefox 36+, Chrome 61+ (therefore also Edge 79+) and Opera 48+.

Intenet Explorer, non-Chromium Edge and (so far) Safari do not support scroll-behavior and simply "jump" to the link target.

Example usage:

<head>
  <style type="text/css">
    html {
      scroll-behavior: smooth;
    }
  </style>
</head>
<body id="body">
  <a href="#foo">Go to foo!</a>

  <!-- Some content -->

  <div id="foo">That's foo.</div>
  <a href="#body">Back to top</a>
</body>

Here's a Fiddle.

And here's also a Fiddle with both horizontal and vertical scrolling.

I like to use gitk name_of_file

This shows a nice list of the changes that happened to a file at each commit, instead of showing the changes to all the files. Makes it easier to track down something that happened.

For your case the only difference is performance: append is twice as fast.

>>> timeit.Timer('s += ["something"]', 's = []').timeit()
0.44208112500000141

In general case append will add one item to the list, while += will copy all elements of right-hand-side list into the left-hand-side list.

Update: perf analysis

Comparing bytecodes we can assume that append version wastes cycles in LOAD_ATTR + CALL_FUNCTION, and += version -- in BUILD_LIST. Apparently BUILD_LIST outweighs LOAD_ATTR + CALL_FUNCTION.

>>> import dis
>>> dis.dis(compile("s = []; s.append('spam')", '', 'exec'))
  1           0 BUILD_LIST               0
              3 STORE_NAME               0 (s)
              6 LOAD_NAME                0 (s)
              9 LOAD_ATTR                1 (append)
             12 LOAD_CONST               0 ('spam')
             15 CALL_FUNCTION            1
             18 POP_TOP
             19 LOAD_CONST               1 (None)
             22 RETURN_VALUE
>>> dis.dis(compile("s = []; s += ['spam']", '', 'exec'))
  1           0 BUILD_LIST               0
              3 STORE_NAME               0 (s)
              6 LOAD_NAME                0 (s)
              9 LOAD_CONST               0 ('spam')
             12 BUILD_LIST               1
             15 INPLACE_ADD
             16 STORE_NAME               0 (s)
             19 LOAD_CONST               1 (None)
             22 RETURN_VALUE

We can improve performance even more by removing LOAD_ATTR overhead:

>>> timeit.Timer('a("something")', 's = []; a = s.append').timeit()
0.15924410999923566

In the HTML (supposing that the checkboxes are in the first column of every row in a table).

<tr ng-repeat="item in fruits">
    <td><input type="checkbox" ng-model="item.checked" ng-click="getChecked(item)"></td>
    <td ng-bind="fruit.name"></td>
    <td ng-bind="fruit.color"></td>
    ...
</tr>

In the controllers.js file:

// The data initialization part...
$scope.fruits = [
    {
      name: ....,
      color:....
    },
    {
      name: ....,
      color:....
    }
     ...
    ];

// The checked or not data is stored in the object array elements themselves
$scope.fruits.forEach(function(item){
    item.checked = false;
});

// The array to store checked fruit items
$scope.checkedItems = [];

// Every click on any checkbox will trigger the filter to find checked items
$scope.getChecked = function(item){
    $scope.checkedItems = $filter("filter")($scope.fruits,{checked:true});
};

Here is a list of special characters that you can escape when creating a string literal for JSON:

\b  Backspace (ASCII code 08)
\f  Form feed (ASCII code 0C)
\n  New line
\r  Carriage return
\t  Tab
\v  Vertical tab
\'  Apostrophe or single quote
\"  Double quote
\\  Backslash character

Reference: String literals

Some of these are more optional than others. For instance, your string should be perfectly valid whether you escape the tab character or leave in a tab literal. You should certainly be handling the backslash and quote characters, though.

All these answers address the title question, but I wanted to propose some solutions for the problems presented in the body of the OP's question.

Size of Text Content

A quick way to calculate the size of the text inside the UITextView is to use the NSLayoutManager:

UITextView *textView;
CGSize textSize = [textView usedRectForTextContainer:textView.textContainer].size;

This gives the total scrollable content, which may be bigger than the UITextView's frame. I found this to be much more accurate than textView.contentSize since it actually calculates how much space the text takes up. For example, given an empty UITextView:

textView.frame.size = (width=246, height=50)
textSize = (width=10, height=16.701999999999998)
textView.contentSize = (width=246, height=33)
textView.textContainerInset = (top=8, left=0, bottom=8, right=0)

Line Height

UIFont has a property that quickly allows you to get the line height for the given font. So you can quickly find the line height of the text in your UITextView with:

UITextView *textView;
CGFloat lineHeight = textView.font.lineHeight;

Calculating Visible Text Size

Determining the amount of text that is actually visible is important for handling a "paging" effect. UITextView has a property called textContainerInset which actually is a margin between the actual UITextView.frame and the text itself. To calculate the real height of the visible frame you can perform the following calculations:

UITextView *textView;
CGFloat textViewHeight = textView.frame.size.height;
UIEdgeInsets textInsets = textView.textContainerInset;
CGFloat textHeight = textViewHeight - textInsets.top - textInsets.bottom;

Determining Paging Size

Lastly, now that you have the visible text size and the content, you can quickly determine what your offsets should be by subtracting the textHeight from the textSize:

// where n is the page number you want
CGFloat pageOffsetY = textSize - textHeight * (n - 1);
textView.contentOffset = CGPointMake(textView.contentOffset.x, pageOffsetY);

// examples
CGFloat page1Offset = 0;
CGFloat page2Offset = textSize - textHeight
CGFloat page3Offset = textSize - textHeight * 2

Using all of these methods, I didn't touch my insets and I was able to go to the caret or wherever in the text that I want.

Since value is the last entry, you can do:

metrics.sort_by(&:last)

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

There is very easy solution to show headers at the top of multi columns list box. Just change the property value to "true" for "columnheads" which is false by default.

After that Just mention the data range in property "rowsource" excluding header from the data range and header should be at first top row of data range then it will pick the header automatically and you header will be freezed.

if suppose you have data in range "A1:H100" and header at "A1:H1" which is the first row then your data range should be "A2:H100" which needs to mention in property "rowsource" and "columnheads" perperty value should be true

If you want to validate individual form field, but don't want for UI to be triggered and display any validation errors, you may consider to use Validator.check() method which returns if given field passes validation or not.

Here is example

var validator = $("#form").data('validator');
if(validator.check('#element')){
    /*field is valid*/
}else{
    /*field is not valid (but no errors will be displayed)*/
}

Use this.getClass().getCanonicalName() to get the full class name.

Note that a package / class name ("a.b.C") is different from the path of the .class files (a/b/C.class), and that using the package name / class name to derive a path is typically bad practice. Sets of class files / packages can be in multiple different class paths, which can be directories or jar files.

The following outlines the similarities and differences to past design techniques:

• SOA versus Structured Programming o Similarities: Most similar to subroutine calls where parameters are passed and the operation of the function is abstracted from the caller - e.g. CICS link and execute and the COBOL CALL reserved word. Copybooks are used to define data structure which is typically defined as an XML schema for services. o Differences: SOA is loosely coupled implying changes to a service have less impact to the consumer (the "calling" program) and services are interoperable across languages and platforms.

• SOA versus OOA/OOD o Similarities: Encapsulation, Abstraction and Defined Interfaces o Differences: SOA is loosely coupled with no class hierarchy or inheritance, Low-level abstractions - class level versus business service

• SOA versus legacy Component Based Development (CBD) - e.g. CORBA, DCOM, EJB o Similarities: Reuse through assembling components, Interfaces, Remote calls o Differences: Wide adoption of standards, XML Schemas vs. Marshaled Objects, Service Orchestration, Designing for reuse is easier, services are business focused vs. IT focused, business services are course grained (broad in scope)

• SOA (for integration) versus Enterprise Application Integration (EAI) o Similarities: Best practices (well defined interfaces, standardized schemas, event driven architecture), reusable interfaces, common schemas o Differences: Standards, adoption, and improved tools

It worked for me after I set up a user with internet access in the Windows service.

In my code:

HttpClientHandler handler = new HttpClientHandler();
handler.Proxy = System.Net.WebRequest.DefaultWebProxy;
handler.Proxy.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
.....
HttpClient httpClient = new HttpClient(handler)
....

It is easy to check for removable devices. However, there's no guarantee that it is a USB device:

var drives = DriveInfo.GetDrives()
    .Where(drive => drive.IsReady && drive.DriveType == DriveType.Removable);

This will return a list of all removable devices that are currently accessible. More information:

• The DriveInfo class (msdn documentation)
• The DriveType enumeration (msdn documentation)

I would like to extend an earnest invitation to any C library maintainers out there who are still including gets in their libraries "just in case anyone is still depending on it": Please replace your implementation with the equivalent of

char *gets(char *str)
{
    strcpy(str, "Never use gets!");
    return str;
}

This will help make sure nobody is still depending on it. Thank you.

I needed to do the same and had to query a query to get the result

I set my first query up to bring in all IDs from the table and all other information needed to filter:

SELECT tMAIN.tLOTS.NoContract, tMAIN.ID
FROM tMAIN INNER JOIN tLOTS ON tMAIN.ID = tLOTS.id
WHERE (((tLOTS.NoContract)=False));

Save this as Q04_1 -0 this returned 1229 results (there are 63 unique records to query - soime with multiple LOTs)

SELECT DISTINCT ID
FROM q04_1;

Saved that as q04_2

I then wrote another query which brought in the required information linked to the ID

SELECT q04_2.ID, tMAIN.Customer, tMAIN.Category
FROM q04_2 INNER JOIN tMAIN ON q04_2.ID = tMAIN.ID;

Worked a treat and got me exactly what I needed - 63 unique records returned with customer and category details.

This is how I worked around it as I couldn't get the Group By working at all - although I am rather "wet behind the ears" weith SQL (so please be gentle and constructive with feedback)

You need to either have the message be a fixed size, or you need to send the size or you need to use some separator characters.

This is the easiest case for a known size (100 bytes):

in = new DataInputStream(server.getInputStream());
byte[] message = new byte[100]; // the well known size
in.readFully(message);

In this case DataInputStream makes sense as it offers readFully(). If you don't use it, you need to loop yourself until the expected number of bytes is read.

I've created a tool that generates TypeScript interfaces and a runtime "type map" for performing runtime typechecking against the results of JSON.parse: ts.quicktype.io

For example, given this JSON:

{
  "name": "David",
  "pets": [
    {
      "name": "Smoochie",
      "species": "rhino"
    }
  ]
}

quicktype produces the following TypeScript interface and type map:

export interface Person {
    name: string;
    pets: Pet[];
}

export interface Pet {
    name:    string;
    species: string;
}

const typeMap: any = {
    Person: {
        name: "string",
        pets: array(object("Pet")),
    },
    Pet: {
        name: "string",
        species: "string",
    },
};

Then we check the result of JSON.parse against the type map:

export function fromJson(json: string): Person {
    return cast(JSON.parse(json), object("Person"));
}

I've left out some code, but you can try quicktype for the details.

When you make the input, set it to be readonly.

<input type="text" name="datepicker" id="datepicker" readonly="readonly" />

getdate() or getutcdate().

If you need just to execute your VLC playback process and only give control back to your application process when it is done and nothing more complex, then i suppose you can use just:

system("The same thing you type into console");

If you want to extract from a tag then

$('.dep_buttons').text().substr(0,25)

With the mouseover event,

$(this).text($(this).text().substr(0, 25));

The above will extract the text of a tag, then extract again assign it back.

If you join the facilities table twice you will get what you are after:

select u.* 
from room u 
  JOIN facilities_r fu1 on fu1.id_uc = u.id_uc and fu1.id_fu = '4'
  JOIN facilities_r fu2 on fu2.id_uc = u.id_uc and fu2.id_fu = '3' 
where 1 and vizibility='1' 
group by id_uc 
order by u_premium desc, id_uc desc

Put the following code before int main():

using namespace std;

And you will be able to use cout.

For example:

#include<iostream>
using namespace std;
int main(){
    char t = 'f';
    char *t1;
    char **t2;
    cout<<t;        
    return 0;
}

Now take a moment and read up on what cout is and what is going on here: http://www.cplusplus.com/reference/iostream/cout/

Further, while its quick to do and it works, this is not exactly a good advice to simply add using namespace std; at the top of your code. For detailed correct approach, please read the answers to this related SO question.

To avoid caching of output you might wanna try pexpect,

child = pexpect.spawn(launchcmd,args,timeout=None)
while True:
    try:
        child.expect('\n')
        print(child.before)
    except pexpect.EOF:
        break

PS : I know this question is pretty old, still providing the solution which worked for me.

PPS: got this answer from another question

By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.

In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.

The client code must set the withCredentials property on the XMLHttpRequest to true in order to give permission.

However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials header. Responding with this header to true means that the server allows cookies (or other user credentials) to be included on cross-origin requests.

You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.

Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

I prefer:

cin.clear();
fflush(stdin);

There's an example where cin.ignore just doesn't cut it, but I can't think of it at the moment. It was a while ago when I needed to use it (with Mingw).

However, fflush(stdin) is undefined behavior according to the standard. fflush() is only meant for output streams. fflush(stdin) only seems to work as expected on Windows (with GCC and MS compilers at least) as an extension to the C standard.

So, if you use it, your code isn't going to be portable.

See Using fflush(stdin).

Also, see http://ubuntuforums.org/showpost.php?s=9129c7bd6e5c8fd67eb332126b59b54c&p=452568&postcount=1 for an alternative.

quite new to Python and I encountered the same issue. I find this solution quite simple and for me it works fine (Python 3.6):

unaware=parser.parse("2020-05-01 0:00:00")
aware=unaware.replace(tzinfo=tz.tzlocal()).astimezone(tz.tzlocal())

To enable you to use the confirm box like the normal confirm dialog, I would use Promises which will enable you to await on the result of the outcome and then act on this, rather than having to use callbacks.

This will allow you to follow the same pattern you have in other parts of your code with code such as...

  const confirm = await ui.confirm('Are you sure you want to do this?');

  if(confirm){
    alert('yes clicked');
  } else{
    alert('no clicked');
  }

See codepen for example, or run the snippet below.

partial answer: pear HTTP_UPLOAD can be usefull http://pear.php.net/manual/en/package.http.http-upload.examples.php

there is a full example for multiple files

Try negation operator ! before $(this):

if (!$(this).parent().next().is('ul')){

The copy() runs for the least length of dst and src, so you must initialize the dst to the desired length.

A := []int{1, 2, 3}
B := make([]int, 3)
copy(B, A)
C := make([]int, 2)
copy(C, A)
fmt.Println(A, B, C)

Output:

[1 2 3] [1 2 3] [1 2]

You can initialize and copy all elements in one line using append() to a nil slice.

x := append([]T{}, []...)

Example:

A := []int{1, 2, 3}
B := append([]int{}, A...)
C := append([]int{}, A[:2]...)
fmt.Println(A, B, C)    

Output:

[1 2 3] [1 2 3] [1 2]

Comparing with allocation+copy(), for greater than 1,000 elements, use append. Actually bellow 1,000 the difference may be neglected, make it a go for rule of thumb unless you have many slices.

You can also use PostCSS and the custom selectors plugin

@custom-selector :--headings h1, h2, h3, h4, h5, h6;

article :--headings {
  margin-top: 0;
}

Output:

article h1,
article h2,
article h3,
article h4,
article h5,
article h6 {
  margin-top: 0;
}

You should use thenReturn or doReturn when you know the return value at the time you mock a method call. This defined value is returned when you invoke the mocked method.

thenReturn(T value) Sets a return value to be returned when the method is called.

@Test
public void test_return() throws Exception {
    Dummy dummy = mock(Dummy.class);
    int returnValue = 5;

    // choose your preferred way
    when(dummy.stringLength("dummy")).thenReturn(returnValue);
    doReturn(returnValue).when(dummy).stringLength("dummy");
}

Answer is used when you need to do additional actions when a mocked method is invoked, e.g. when you need to compute the return value based on the parameters of this method call.

Use doAnswer() when you want to stub a void method with generic Answer.

Answer specifies an action that is executed and a return value that is returned when you interact with the mock.

@Test
public void test_answer() throws Exception {
    Dummy dummy = mock(Dummy.class);
    Answer<Integer> answer = new Answer<Integer>() {
        public Integer answer(InvocationOnMock invocation) throws Throwable {
            String string = invocation.getArgumentAt(0, String.class);
            return string.length() * 2;
        }
    };

    // choose your preferred way
    when(dummy.stringLength("dummy")).thenAnswer(answer);
    doAnswer(answer).when(dummy).stringLength("dummy");
}

For the best practice - use style="display:"

it will work every where..

You may set this in your application.yml file to resolve Instant time, which is Date API in java8:

spring.jackson.serialization.write-dates-as-timestamps=false

Try this code:

import android.os.Handler;
...
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        // Do something after 5s = 5000ms
        buttons[inew][jnew].setBackgroundColor(Color.BLACK);
    }
}, 5000);

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

Update for RxJS 6 (April 2018)

It is now perfectly fine to import directly from rxjs. (As can be seen in Angular 6+). Importing from rxjs/operators is also fine and it is actually no longer possible to import operators globally (one of major reasons for refactoring rxjs 6 and the new approach using pipe). Thanks to this treeshaking can now be used as well.

Sample code from rxjs repo:

import { Observable, Subject, ReplaySubject, from, of, range } from 'rxjs';
import { map, filter, switchMap } from 'rxjs/operators';

range(1, 200)
  .pipe(filter(x => x % 2 === 1), map(x => x + x))
  .subscribe(x => console.log(x));

Backwards compatibility for rxjs < 6?

rxjs team released a compatibility package on npm that is pretty much install & play. With this all your rxjs 5.x code should run without any issues. This is especially useful now when most of the dependencies (i.e. modules for Angular) are not yet updated.

Shorter version:

db.row_factory = lambda c, r: dict([(col[0], r[idx]) for idx, col in enumerate(c.description)])

I've faced the exactly same problem but I've fixed it with another approache.

Using Ubuntu 18.04, first disable systemd-resolved service.

sudo systemctl disable systemd-resolved.service

Stop the service

sudo systemctl stop systemd-resolved.service

Then, remove the link to /run/systemd/resolve/stub-resolv.conf in /etc/resolv.conf

sudo rm /etc/resolv.conf

Add a manually created resolv.conf in /etc/

sudo vim /etc/resolv.conf

Add your prefered DNS server there

nameserver 208.67.222.222

I've tested this with success.

This works after you delete the related dependency from your local maven repository

/user/.m2/repository/path

Well I fond this post because I got a similar error. So I added the top line like in your controller respond_to :html, :json

then I got a different error(see below)

The controller-level respond_to' feature has been extracted to theresponders` gem. Add it to your Gemfile to continue using this feature: gem 'responders', '~> 2.0' Consult the Rails upgrade guide for details. But that had nothing to do with it.

It could also be because, it might not be able to found the .dll file required. Either the file is not in the folder or is renamed. I faced the same issue and found that .dll file was missing in my bin folder some how.

The conceptual differences between NULL and "empty-string" are real and very important in database design, but often misunderstood and improperly applied - here's a short description of the two:

NULL - means that we do NOT know what the value is, it may exist, but it may not exist, we just don't know.

Empty-String - means we know what the value is and that it is nothing.

Here's a simple example: Suppose you have a table with people's names including separate columns for first_name, middle_name, and last_name. In the scenario where first_name = 'John', last_name = 'Doe', and middle_name IS NULL, it means that we do not know what the middle name is, or if it even exists. Change that scenario such that middle_name = '' (i.e. empty-string), and it now means that we know that there is no middle name.

I once heard a SQL Server instructor promote making every character type column in a database required, and then assigning a DEFAULT VALUE to each of either '' (empty-string), or 'unknown'. In stating this, the instructor demonstrated he did not have a clear understanding of the difference between NULLs and empty-strings. Admittedly, the differences can seem confusing, but for me the above example helps to clarify the difference. Also, it is important to understand the difference when writing SQL code, and properly handle for NULLs as well as empty-strings.

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

When you want to convert your code to result( executable, library or whatever ), there is 2 steps:
1) compile
2) link
In first step compiler should now about some things like sizeof objects that used by you, prototype of functions and maybe inheritance. on the other hand linker want to find implementation of functions and global variables in your code.

Now when you use ClassTwo in File1.cpp compiler know nothing about it and don't know how much memory should allocate for it or for example witch members it have or is it a class and enum or even a typedef of int, so compilation will be failed by the compiler. adding File2.cpp solve the problem of linker that look for implementation but the compiler is still unhappy, because it know nothing about your type.

So remember, in compile phase you always work with just one file( and of course files that included by that one file ) and in link phase you need multiple files that contain implementations. and since C/C++ are statically typed and they allow their identifier to work for many purposes( definition, typedef, enum class, ... ) so you should always identify you identifier to the compiler and then use it and as a rule compiler should always know size of your variable!!
