APC definitely. It's written by the PHP guys, so even though it might not share the highest speeds, you can bet on the fact it's the highest quality.

Plus you get some other nifty features I use all the time (http://www.php.net/apc).

Just make sure you have the .htaccess in your project's public directory

If you don't have the file then create one and paste the below code in your .htaccess file.

Code:-

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

As suggested in other answers it's probably easiest to "POST" the form data to the controller. If you need to pass an entire Model/Form you can easily do this with serialize() e.g.

$('#myform').on('submit', function(e){
    e.preventDefault();

    var formData = $(this).serialize();

    $.post('/student/update', formData, function(response){
         //Do something with response
    });
});

So your controller could have a view model as the param e.g.

 [HttpPost]
 public JsonResult Update(StudentViewModel studentViewModel)
 {}

Alternatively if you just want to post some specific values you can do:

$('#myform').on('submit', function(e){
    e.preventDefault();

    var studentId = $(this).find('#Student_StudentId');
    var isActive = $(this).find('#Student_IsActive');

    $.post('/my/url', {studentId : studentId, isActive : isActive}, function(response){
         //Do something with response
    });
});

With a controller like:

     [HttpPost]
     public JsonResult Update(int studentId, bool isActive)
     {}

As a sidenote to @Navaneethan 's answer, Jinja2 is able to do "regular" item selections for the list and the dictionary, given we know the key of the dictionary, or the locations of items in the list.

Data:

parent_dict = [{'A':'val1','B':'val2', 'content': [["1.1", "2.2"]]},{'A':'val3','B':'val4', 'content': [["3.3", "4.4"]]}]

in Jinja2 iteration:

{% for dict_item in parent_dict %}
   This example has {{dict_item['A']}} and {{dict_item['B']}}:
       with the content --
       {% for item in dict_item['content'] %}{{item[0]}} and {{item[1]}}{% endfor %}.
{% endfor %}

The rendered output:

This example has val1 and val2:
    with the content --
    1.1 and 2.2.

This example has val3 and val4:
   with the content --
   3.3 and 4.4.

Well, quick answer would to take a look at the 'scp' manpage, or perhaps rsync - depending exactly on what you need to copy. If you had to, you could even do tar-over-ssh:

tar cvf - | ssh server tar xf -

Something very similar can be seen on http://goo.gl when you shorten the URL.

There is a readonly input element that gets programmatically focused, with tooltip press CTRL-C to copy.

When you hit that shortcut, the input content effectively gets into the clipboard. Really nice :)

If the position index of the text node is fixed among its siblings, you can use

$('parentselector').contents().eq(index).text()

As stated in problem, to solve this error you MUST use correct annotations. In above problem, @NotBlank or @NotEmpty annotation must be applied on any String field only.

To validate long type field, use annotation @NotNull.

Yes, this sort of thing is possible without Flash:

• http://hacks.mozilla.org/2009/06/tristan-washing-machine/
• http://jakearchibald.com/scratch/alphavid/

However, only very modern browsers supports HTML5 videos, and this should be your consideration when deploying in HTML 5, and you should provide a fallback (probably Flash or just omit the transparency).

The normal way to install Python libraries is with pip. Your way of installing it for Python 3.2 works because it's the system Python, and that's the way to install things for system-provided Pythons on Debian-based systems.

If your Python 3.3 is system-provided, you should probably use a similar command. Otherwise you should probably use pip.

I took my Python 3.3 installation, created a virtualenv and run pip install in it, and that seems to have worked as expected:

$ virtualenv-3.3 testenv
$ cd testenv
$ bin/pip install numpy
blablabl

$ bin/python3
Python 3.3.2 (default, Jun 17 2013, 17:49:21) 
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.

There are jQuery events like keyup and keypress which you can use with input HTML Elements. You could additionally use the blur() event.

import urllib
import json

url = 'http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false'
result = json.load(urllib.urlopen(url))

I have solved it this way.

Go to your project file let's say project/name/bin and delete everything within the bin folder. (this will then give you another error which you can solve this way)

then in your visual studio right click project's References folder, to open NuGet Package Manager.

Go to browse and install "DotNetCompilerPlatform".

Given you've set up a git daemon on <url> and an empty repository:

cd <localdir>
git init
git add .
git commit -m 'message'
git remote add origin <url>
git push -u origin master

Try specifying a DC in DomainB using the -Server property. Ex:

Get-ADUser -Server "dc01.DomainB.local" -Filter {EmailAddress -like "*Smith_Karla*"} -Properties EmailAddress

int abc= (Math.random()*100);//  wrong 

you wil get below error message

Exception in thread "main" java.lang.Error: Unresolved compilation problem: Type mismatch: cannot convert from double to int

int abc= (int) (Math.random()*100);// add "(int)" data type

,known as type casting

if the true result is

int abc= (int) (Math.random()*1)=0.027475

Then you will get output as "0" because it is a integer data type.

int abc= (int) (Math.random()*100)=0.02745

output:2 because (100*0.02745=2.7456...etc)

I like Consolas a lot. This top-10 list is a good resource for others. It includes examples and descriptions.

Or, once it's already in SSIS, you could create a derived column (as part of some data flow task) with:

(DT_I8)FLOOR((DT_R8)systemDateTime)

But you'd have to test to doublecheck.

Also, if you're using Rails 3 or newer you don't have to use the up and down methods. You can just use change:

class ChangeFormatInMyTable < ActiveRecord::Migration
  def change
    change_column :my_table, :my_column, :my_new_type
  end
end

A project's build path defines which resources from your source folders are copied to your output folders. Usually this is set to Include all files.

New run configurations default to using the project directory for the working directory, though this can also be changed.

This code shows the difference between the working directory, and the location of where the class was loaded from:

public class TellMeMyWorkingDirectory {
    public static void main(String[] args) {
        System.out.println(new java.io.File("").getAbsolutePath());
        System.out.println(TellMeMyWorkingDirectory.class.getClassLoader().getResource("").getPath());
    }
}

The output is likely to be something like:

C:\your\project\directory
/C:/your/project/directory/bin/

It can be caused by:

1. Invalid HTML syntax (some tag is not closed or similar error)
2. Duplicate IDs - there are two HTML DOM elements with the same ID
3. Maybe element you are trying to get by ID is created dynamically (loaded by ajax or created by script)?

Please, post your code.

The question was answered perfectly by Darin Dimitrov, but since ASP.NET 4.5, there is now a better way to set up these bindings to replace* Eval() and Bind(), taking advantage of the strongly-typed bindings.

*Note: this will only work if you're not using a SqlDataSource or an anonymous object. It requires a Strongly-typed object (from an EF model or any other class).

This code snippet shows how Eval and Bind would be used for a ListView control (InsertItem needs Bind, as explained by Darin Dimitrov above, and ItemTemplate is read-only (hence they're labels), so just needs an Eval):

<asp:ListView ID="ListView1" runat="server" DataKeyNames="Id" InsertItemPosition="LastItem" SelectMethod="ListView1_GetData" InsertMethod="ListView1_InsertItem" DeleteMethod="ListView1_DeleteItem">
    <InsertItemTemplate>
        <li>
            Title: <asp:TextBox ID="Title" runat="server" Text='<%# Bind("Title") %>'/><br />         
            Description: <asp:TextBox ID="Description" runat="server" TextMode="MultiLine" Text='<%# Bind("Description") %>' /><br />        
            <asp:Button ID="InsertButton" runat="server" Text="Insert" CommandName="Insert" />        
        </li>
    </InsertItemTemplate>
    <ItemTemplate>
        <li>
            Title: <asp:Label ID="Title" runat="server" Text='<%#  Eval("Title") %>' /><br />
            Description: <asp:Label ID="Description" runat="server" Text='<%# Eval("Description") %>' /><br />        
            <asp:Button ID="DeleteButton" runat="server" Text="Delete" CommandName="Delete" CausesValidation="false"/>
        </li>
      </ItemTemplate>

From ASP.NET 4.5+, data-bound controls have been extended with a new property ItemType, which points to the type of object you're assigning to its data source.

<asp:ListView ItemType="Picture" ID="ListView1" runat="server" ...>

Picture is the strongly type object (from EF model). We then replace:

Bind(property) -> BindItem.property
Eval(property) -> Item.property

So this:

<%# Bind("Title") %>      
<%# Bind("Description") %>         
<%#  Eval("Title") %> 
<%# Eval("Description") %>

Would become this:

<%# BindItem.Title %>         
<%# BindItem.Description %>
<%# Item.Title %>
<%# Item.Description %>

Advantages over Eval & Bind:

• IntelliSense can find the correct property of the object your're working with
• If property is renamed/deleted, you will get an error before page is viewed in browser
• External tools (requires full versions of VS) will correctly rename item in markup when you rename a property on your object

Surprisingly there is no accepted answer. The issue only exists in 32-bit PHP.

From the documentation,

If the string does not contain any of the characters '.', 'e', or 'E' and the numeric value fits into integer type limits (as defined by PHP_INT_MAX), the string will be evaluated as an integer. In all other cases it will be evaluated as a float.

In other words, the $string is first interpreted as INT, which cause overflow (The $string value 2968789218 exceeds the maximum value (PHP_INT_MAX) of 32-bit PHP, which is 2147483647.), then evaluated to float by (float) or floatval().

Thus, the solution is:

$string = "2968789218";
echo 'Original: ' . floatval($string) . PHP_EOL;
$string.= ".0";
$float = floatval($string);
echo 'Corrected: ' . $float . PHP_EOL;

which outputs:

Original: 2.00
Corrected: 2968789218

To check whether your PHP is 32-bit or 64-bit, you can:

echo PHP_INT_MAX;

If your PHP is 64-bit, it will print out 9223372036854775807, otherwise it will print out 2147483647.

Thanks a lot for the first answer.

As for me, I had just one problem with it. When inflating my view, i had a bug : java.lang.NoSuchMethodException : MyView(Context, Attributes)

I resolved it by creating a new constructor :

public MyView(Context context, AttributeSet attrs) {
     super(context, attrs);
     // some code
}

Hope this will help !

I've done some research and it seems that the sys.argv might require an argument at the command line when running the script

Not might, but definitely requires. That's the whole point of sys.argv, it contains the command line arguments. Like any python array, accesing non-existent element raises IndexError.

Although the code uses try/except to trap some errors, the offending statement occurs in the first line.

So the script needs a directory name, and you can test if there is one by looking at len(sys.argv) and comparing to 1+number_of_requirements. The argv always contains the script name plus any user supplied parameters, usually space delimited but the user can override the space-split through quoting. If the user does not supply the argument, your choices are supplying a default, prompting the user, or printing an exit error message.

To print an error and exit when the argument is missing, add this line before the first use of sys.argv:

if len(sys.argv)<2:
    print "Fatal: You forgot to include the directory name on the command line."
    print "Usage:  python %s <directoryname>" % sys.argv[0]
    sys.exit(1)

sys.argv[0] always contains the script name, and user inputs are placed in subsequent slots 1, 2, ...

Just to correct mingos' answer:

If you set the expiration time to 0, the cookie won't be created at all. I've tested this on Google Chrome at least, and when set to 0 that was the result. The cookie, I guess, expires immediately after creation.

To set a cookie so it expires at the end of the browsing session, simply OMIT the expiration parameter altogether.

Example:

Instead of:

document.cookie = "cookie_name=cookie_value; 0; path=/";

Just write:

document.cookie = "cookie_name=cookie_value; path=/";

You are missing the border width and the border style properties in the Border shorthand property :

.circle {
    border: 2px solid red;
    background-color: #FFFFFF;
    height: 100px;
    border-radius:50%;
    width: 100px;
}

<div class="circle"></div>

Also, You can use percentages for the border-radius property so that the value isn't dependent of the circle width/height. That is why I used 50% for border-radius (more info on border-radius in pixels and percent).

Side note : In your example, you didn't specify the border-radius property without vendor prefixes whitch you propably don't need as only browsers before chrome 4 safari 4 and Firefox 3.6 use them (see canIuse).

Use this code:

QFile inputFile(fileName);
if (inputFile.open(QIODevice::ReadOnly))
{
   QTextStream in(&inputFile);
   while (!in.atEnd())
   {
      QString line = in.readLine();
      ...
   }
   inputFile.close();
}

Easiest modern method: Alt+Enter on

private static final long serialVersionUID = ;

IntelliJ will underline the space after the =. put your cursor on it and hit alt+Enter (Option+Enter on Mac). You'll get a popover that says "Randomly Change serialVersionUID Initializer". Just hit enter, and it'll populate that space with a random long.

it depends on the content really : content.frame.height might give you what you want ? Depends if content is a single thing, or a collection of things.

Question already answered by the OP, but I am posting this answer for anyone having similar problem, retting to

Could not input open file: composer.phar

error message.

Simply go to your project directory/folder and do a

composer update

Assuming this is where you have your web application:

/Library/WebServer/Documents/zendframework

change directory to it, and then run composer update.

if (a % 2 == 0) {
} else {
}

I had this problem recently where apt install wget does not find anything. As it turns out apt update was never run.

apt update
apt install wget

After discussing this with a coworker we mused that apt update is likely not run in order to save both time and space in the docker image.

If you don't care about the return value you could just use Runtime.getRuntime().exec("path.to.your.batch.file");

I think I just discovered a way to apply overlapping conditions in the expected way using VBA. After hours of trying out different approaches I found that what worked was changing the "Applies to" range for the conditional format rule, after every single one was created!

An old question without a data.table solution. So here goes...

Using .N

library(data.table)
DT <- data.table(df)
DT[, .N, by = list(year, month)]

A simple solution might be to just store the drawable id in a temporary variable. I'm not sure how practical this would be for your situation but it's definitely a quick fix.

Another pure Java variation:

public boolean isWithin30Days(Calendar queryCalendar) {

    // 1. Take the date you are checking, and roll it back N days
    Calendar queryCalMinus30Days = Calendar.getInstance();
    queryCalMinus30Days.setTime(queryCalendar.getTime());
    queryCalMinus30Days.add(Calendar.DATE, -30); // subtract 30 days from the calendar

    // 2. Get respective milliseconds for the two Calendars: now & queryCal minus N days 
    long nowL = Calendar.getInstance().getTimeInMillis();
    long queryCalMinus30DaysL = queryCalMinus30Days.getTimeInMillis();

    // 3. if nowL is still less than the queryCalMinus30DaysL, it means queryCalendar is more than 30 days into future
    boolean isWithin30Days = nowL >= queryCalMinus30DaysL;

    return isWithin30Days;
}

Based on John's answer, I changed the GET request to a POST request. It works, without having to change the server configuration. So I went looking how to implement this. The following pages were helpful:

jQuery Ajax POST example with PHP (Note the sanitize posted data remark) and

http://www.openjs.com/articles/ajax_xmlhttp_using_post.php

Basically, the difference is that the GET request has the url and parameters in one string and then sends null:

http.open("GET", url+"?"+params, true);
http.send(null);

whereas the POST request sends the url and the parameters in separate commands:

http.open("POST", url, true);
http.send(params);

Here is a working example:

ajaxPOST.html:

<html>
<head>
<script type="text/javascript">
    function ajaxPOSTTest() {
        try {
            // Opera 8.0+, Firefox, Safari
            ajaxPOSTTestRequest = new XMLHttpRequest();
        } catch (e) {
            // Internet Explorer Browsers
            try {
                ajaxPOSTTestRequest = new ActiveXObject("Msxml2.XMLHTTP");
            } catch (e) {
                try {
                    ajaxPOSTTestRequest = new ActiveXObject("Microsoft.XMLHTTP");
                } catch (e) {
                    // Something went wrong
                    alert("Your browser broke!");
                    return false;
                }
            }
        }

        ajaxPOSTTestRequest.onreadystatechange = ajaxCalled_POSTTest;
        var url = "ajaxPOST.php";
        var params = "lorem=ipsum&name=binny";
        ajaxPOSTTestRequest.open("POST", url, true);
        ajaxPOSTTestRequest.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        ajaxPOSTTestRequest.send(params);
    }

    //Create a function that will receive data sent from the server
    function ajaxCalled_POSTTest() {
        if (ajaxPOSTTestRequest.readyState == 4) {
            document.getElementById("output").innerHTML = ajaxPOSTTestRequest.responseText;
        }
    }
</script>

</head>
<body>
    <button onclick="ajaxPOSTTest()">ajax POST Test</button>
    <div id="output"></div>
</body>
</html>

ajaxPOST.php:

<?php

$lorem=$_POST['lorem'];
print $lorem.'<br>';

?>

I just sent over 12,000 characters without any problems.

I was having the same problem. Using ResultSet.first() in this way just after the execution solved it:

if(rs.first()){
    // Do your job
} else {
    // No rows take some actions
}

Documentation (link):

boolean first()
    throws SQLException

Moves the cursor to the first row in this ResultSet object.

Returns:

true if the cursor is on a valid row; false if there are no rows in the result set

Throws:

SQLException - if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY

SQLFeatureNotSupportedException - if the JDBC driver does not support this method

For Converting a List into Pandas Core Data Frame, we need to use DataFrame Method from pandas Package.

There are Different Ways to Perform the Above Operation.

import pandas as pd

1. pd.DataFrame({'Column_Name':Column_Data})

• Column_Name : String
• Column_Data : List Form

2. Data = pd.DataFrame(Column_Data)

   Data.columns = ['Column_Name']

So, for the above mentioned issue, the code snippet is

import pandas as pd

Content = ['Thanks You',
           'Its fine no problem',
           'Are you sure']

Data = pd.DataFrame({'Text': Content})

Following solution is clean and works perfectly.

1. Download Elevate zip file from https://www.winability.com/download/Elevate.zip

2. Inside zip you should find two files: Elevate.exe and Elevate64.exe. (The latter is a native 64-bit compilation, if you require that, although the regular 32-bit version, Elevate.exe, should work fine with both the 32- and 64-bit versions of Windows)

3. Copy the file Elevate.exe into a folder where Windows can always find it (such as C:/Windows). Or you better you can copy in same folder where you are planning to keep your bat file.

4. To use it in a batch file, just prepend the command you want to execute as administrator with the elevate command, like this:

 elevate net start service ...

On onItemClick :

String text = parent.getItemAtPosition(position).toString();

Use background-position:

background-position: 50% 50%;

mylist = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")]
print mylist
j=0
for i in mylist:
    mylist[j]=i.rstrip("8")
    j+=1
print mylist

On my Windows 10 Enterprise, gulp was not installed in %AppData%, which is C:\Users\username\AppData\npm\node_modules on my machine, but in C:\Users\username\AppData\Local\npm\node_modules.

To get gulp to be picked up at the command prompt or in powershell, I added to the user PATH the value C:\Users\username\AppData\Local\npm. After that it worked like a charm. Naturally I had to close the command prompt or powershell window and re-open for the above to take effect.

The simplest way to put an image into a button:

<button onclick="myFunction()"><img src="your image name here.png"></button>

This will automatically resize the button to the size of the image.

This is the solution for my old question:

I implemented my own ContextResolver in order to enable the DeserializationConfig.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY feature.

package org.lig.hadas.services.mapper;

import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;

import org.codehaus.jackson.map.DeserializationConfig;
import org.codehaus.jackson.map.ObjectMapper;

@Produces(MediaType.APPLICATION_JSON)
@Provider
public class ObjectMapperProvider implements ContextResolver<ObjectMapper>
{
   ObjectMapper mapper;

   public ObjectMapperProvider(){
       mapper = new ObjectMapper();
       mapper.configure(DeserializationConfig.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY, true);
   }
   @Override
   public ObjectMapper getContext(Class<?> type) {
       return mapper;
   }
}

And in the web.xml I registered my package into the servlet definition...

<servlet>
    <servlet-name>...</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>...;org.lig.hadas.services.mapper</param-value>        
    </init-param>
    ...
</servlet>

... all the rest is transparently done by jersey/jackson.

If you want to use forward slashes in the format, the you need to escape with back slashes in the regex:

   _x000D_
var dateformat = /^(0?[1-9]|1[012])[\/\-](0?[1-9]|[12][0-9]|3[01])[\/\-]\d{4}$/;

you should change cr_date(str) to datetime object then you 'll change the date to the specific format:

cr_date = '2013-10-31 18:23:29.000227'
cr_date = datetime.datetime.strptime(cr_date, '%Y-%m-%d %H:%M:%S.%f')
cr_date = cr_date.strftime("%m/%d/%Y")

In CMD, '&&' means "execute command 1, and if it succeeds, execute command 2". I have used it for things like:

build && run_tests

In PowerShell, the closest thing you can do is:

(build) -and (run_tests)

It has the same logic, but the output text from the commands is lost. Maybe it is good enough for you, though.

If you're doing this in a script, you will probably be better off separating the statements, like this:

build
if ($?) {
    run_tests
}

2019/11/27: The &&operator is now available for PowerShell 7 Preview 5+:

PS > echo "Hello!" && echo "World!"
Hello!
World!

The easiest way is to handle all of your database interactions in its own module that you export to your routes. If your route has no context of the database then SQL can't touch it anyway.

you can also use this:

echo $pageName = basename($_SERVER['SCRIPT_NAME']);

You could try using Strings with a separator which does not appear in any element.

if ("|a|b|c|".contains("|a|"))

Execute the following command

sudo setfacl -R -m u:<user_name>:rwx /var/www

It will change the permissions of html directory so that you can upload, download and delete the files or directories

Find the tag as type="file". this the main tag which is supported by selenium. If you are able to build your XPath with same when it is recommended.

• use sendkeys for the button having browse option(The button which will open your window box to select files)
• Now click on the button which is going to upload your file

As below :-

driver.findElement(By.xpath("//input[@id='files']")).sendKeys("D:"+File.separator+"images"+File.separator+"Lighthouse.jpg"");
Thread.sleep(5000);    
driver.findElement(By.xpath("//button[@id='Upload']")).click(); 

For multiple file upload put all files one by one by sendkeys and then click on upload

driver.findElement(By.xpath("//input[@id='files']")).sendKeys("D:"+File.separator+"images"+File.separator+"Lighthouse.jpg"");  
driver.findElement(By.xpath("//input[@id='files']")).sendKeys("D:"+File.separator+"images"+File.separator+"home.jpg");
driver.findElement(By.xpath("//input[@id='files']")).sendKeys("D:"+File.separator+"images"+File.separator+"tsquare.jpg");
Thread.sleep(5000); 
driver.findElement(By.xpath("//button[@id='Upload']")).click(); // Upload button

You're searching for gc_maxlifetime, see http://php.net/manual/en/session.configuration.php#ini.session.gc-maxlifetime for a description.

Your session will last 1440 seconds which is 24 minutes (default).

I'll slightly expand @assylias answer to take time zone into account. There are at least two ways to get LocalDateTime for specific time zone.

You can use setDefault time zone for whole application. It should be called before any timestamp -> java.time conversion:

public static void main(String... args) {
    TimeZone utcTimeZone = TimeZone.getTimeZone("UTC");
    TimeZone.setDefault(utcTimeZone);
    ...
    timestamp.toLocalDateTime().toLocalDate();
}

Or you can use toInstant.atZone chain:

timestamp.toInstant()
        .atZone(ZoneId.of("UTC"))
        .toLocalDate();

mysqli_fetch_array() returns NULL if there is no row.

In procedural style:

if ( ! $row = mysqli_fetch_array( $result ) ) {
    ... no result ...
}
else {
    ... get the first result in $row ...
}

In Object oriented style:

if ( ! $row = $result->fetch_array() ) {
    ...
}
else {
    ... get the first result in $row ...
}

To center text in a UILabel in Swift (which is targeted for iOS 7+) you can do:

myUILabel.textAlignment = .Center

Or

myUILabel.textAlignment = NSTextAlignment.Center

I can think of An Array inside an Array or a Guava's MultiMap?

e.g.

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

In the model, write the below code;

public $timestamps = false;

This would work.

Explanation : By default laravel will expect created_at & updated_at column in your table. By making it to false it will override the default setting.

Here is my implementation:

from bisect import bisect

def to_filesize(bytes_num, si=True):
    decade = 1000 if si else 1024
    partitions = tuple(decade ** n for n in range(1, 6))
    suffixes = tuple('BKMGTP')

    i = bisect(partitions, bytes_num)
    s = suffixes[i]

    for n in range(i):
        bytes_num /= decade

    f = '{:.3f}'.format(bytes_num)

    return '{}{}'.format(f.rstrip('0').rstrip('.'), s)

It will print up to three decimals and it strips trailing zeros and periods. The boolean parameter si will toggle usage of 10-based vs. 2-based size magnitude.

This is its counterpart. It allows to write clean configuration files like {'maximum_filesize': from_filesize('10M'). It returns an integer that approximates the intended filesize. I am not using bit shifting because the source value is a floating point number (it will accept from_filesize('2.15M') just fine). Converting it to an integer/decimal would work but makes the code more complicated and it already works as it is.

def from_filesize(spec, si=True):
    decade = 1000 if si else 1024
    suffixes = tuple('BKMGTP')

    num = float(spec[:-1])
    s = spec[-1]
    i = suffixes.index(s)

    for n in range(i):
        num *= decade

    return int(num)

setInterval function is the one that has to be used. Here is an example for the same without any fancy fading option. Simple Javascript that does an image change every 30 seconds. I have assumed that the images were kept in a separate images folder and hence _images/ is present at the beginning of every image. You can have your own path as required to be set.

CODE:

var im = document.getElementById("img");

var images = ["_images/image1.jpg","_images/image2.jpg","_images/image3.jpg"];
var index=0;

function changeImage()
{
  im.setAttribute("src", images[index]);
  index++;
  if(index >= images.length)
  {
    index=0;
  }
}

setInterval(changeImage, 30000);

I follow the following instruction to create a executable .jar in Eclipse. Then Run command "java -jar .jar " to launch the program.

It takes care of creating mainfest and includeing main class and library files parts for you.

I have constructed this JavaScript script to parse a CSV in string to array object. I find it better to break down the whole CSV into lines, fields and process them accordingly. I think that it will make it easy for you to change the code to suit your need.

    //
    //
    // CSV to object
    //
    //

    const new_line_char = '\n';
    const field_separator_char = ',';

        var result = [];

        let line_end_index_moved = false;
        let line_start_index = 0;
        let line_end_index = 0;
        let csr_index = 0;
        let cursor_val = csv_str[csr_index];
        let found_new_line_char = get_new_line_char(csv_str);
        let in_quote = false;

        // Handle \r\n
        if (found_new_line_char == '\r\n') {
            csv_str = csv_str.split(found_new_line_char).join(new_line_char);
        }
        // Handle the last character is not \n
        if (csv_str[csv_str.length - 1] !== new_line_char) {
            csv_str += new_line_char;
        }

        while (csr_index < csv_str.length) {

Use <div contenteditable="true"> (supported well) with storing to <input type="hidden">.

HTML:

<div id="multilineinput" contenteditable="true"></div>
<input type="hidden" id="detailsfield" name="detailsfield">

js (using jQuery)

$("#multilineinput").on('keyup',function(e) {   
    $("#detailsfield").val($(this).text()); //store content to input[type=hidden]
});
//optional - one line but wrap it
$("#multilineinput").on('keypress',function(e) {    
    if(e.which == 13) { //on enter
        e.preventDefault(); //disallow newlines     
        // here comes your code to submit
    }
});

You are better off using a native array instead of an object literal with number-like properties, so that numbering (as well as numerous other array functions) are taken care of off-the-shelf.

What you are looking for here is an inline interface definition for your array that defines every element in that array, whether initially present or introduced later:

let userTestStatus: { id: number, name: string }[] = [
    { "id": 0, "name": "Available" },
    { "id": 1, "name": "Ready" },
    { "id": 2, "name": "Started" }
];

userTestStatus[34978].nammme; // Error: Property 'nammme' does not exist on type [...]

If you are initializing your array with values right away, the explicit type definition is not a necessity; TypeScript can automatically infer most element types from the initial assignment:

let userTestStatus = [
    { "id": 0, "name": "Available" },
    ...
];

userTestStatus[34978].nammme; // Error: Property 'nammme' does not exist on type [...]

It turns out there's a very important distinction between the two methods: first() will emit an error if the stream completes before a value is emitted. Or, if you've provided a predicate (i.e. first(value => value === 'foo')), it will emit an error if the stream completes before a value that passes the predicate is emitted.

take(1), on the other hand, will happily carry on if a value is never emitted from the stream. Here's a simple example:

const subject$ = new Subject();

// logs "no elements in sequence" when the subject completes
subject$.first().subscribe(null, (err) => console.log(err.message));

// never does anything
subject$.take(1).subscribe(console.log);

subject$.complete();

Another example, using a predicate:

const observable$ = of(1, 2, 3);

// logs "no elements in sequence" when the observable completes
observable$
 .first((value) => value > 5)
 .subscribe(null, (err) => console.log(err.message));

// the above can also be written like this, and will never do
// anything because the filter predicate will never return true
observable$
 .filter((value) => value > 5);
 .take(1)
 .subscribe(console.log);

As a newcomer to RxJS, this behavior was very confusing to me, although it was my own fault because I made some incorrect assumptions. If I had bothered to check the docs, I would have seen that the behavior is clearly documented:

Throws an error if defaultValue was not provided and a matching element is not found.

The reason I've run into this so frequently is a fairly common Angular 2 pattern where observables are cleaned up manually during the OnDestroy lifecycle hook:

class MyComponent implements OnInit, OnDestroy {
  private stream$: Subject = someDelayedStream();
  private destroy$ = new Subject();

  ngOnInit() {
    this.stream$
      .takeUntil(this.destroy$)
      .first()
      .subscribe(doSomething);
  }

  ngOnDestroy() {
    this.destroy$.next(true);
  }
}

The code looks harmless at first, but problems arise when the component in destroyed before stream$ can emit a value. Because I'm using first(), an error is thrown when the component is destroyed. I'm usually only subscribing to a stream to get a value that is to be used within the component, so I don't care if the component gets destroyed before the stream emits. Because of this, I've started using take(1) in almost all places where I would have previously used first().

filter(fn).take(1) is a bit more verbose than first(fn), but in most cases I prefer a little more verbosity over handling errors that ultimately have no impact on the application.

Also important to note: The same applies for last() and takeLast(1).

reference

Date's compareTo() you're using will work for ascending order.

To do descending, just reverse the value of compareTo() coming out. You can use a single Comparator class that takes in a flag/enum in the constructor that identifies the sort order

public int compare(MyObject lhs, MyObject rhs) {

    if(SortDirection.Ascending == m_sortDirection) {
        return lhs.MyDateTime.compareTo(rhs.MyDateTime);
    }

    return rhs.MyDateTime.compareTo(lhs.MyDateTime);
}

You need to call Collections.sort() to actually sort the list.

As a side note, I'm not sure why you're defining your map inside your for loop. I'm not exactly sure what your code is trying to do, but I assume you want to populate the indexed values from your for loop in to the map.

This issue is almost invariably a simple one. The code is bad. It's rarely the tools, just from a statistical analysis. Untold millions of people are using Visual Studio every day and maybe a few are using your code - which bit of code is getting the better testing? I guarantee that, if this were a problem with VS, we would probably already have found it.

What the statement means is that, when you try to access memory that isn't yours, it's usually because you're doing it with a corrupted pointer, that came from somewhere else. That's why it's stating the indication.

With memory corruption, the catching of the error is rarely near the root cause of the error. And the effects are exactly what you describe, seemingly random. You'll just have to look at the usual culprits, things like:

• uninitialised pointers or other values.
• writing more to a buffer than its size.
• resources shared by threads that aren't protected by mutexes.

Working backwards from a problem like this to find the root cause is incredibly difficult given that so much could have happened between the creation of the problem and the detection of the problem.

I mostly find it's easier to have a look at what is corrupt (say, a specific pointer) and then do manual static analysis of the code to see what could have corrupted it, checking for the usual culprits as shown above. However, even this won't catch long chains of problems.

I'm not familiar enough with VS to know but you may also want to look into the possibility of using a memory tracking tool (like valgrind for Linux) to see if it can spot any obvious issues.

In Kotlin, I am using a class DoubleButtonDialog.Java with line window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT)) as important one

class DoubleButtonDialog(context: Context) : Dialog(context, R.style.DialogTheme) {

    private var cancelableDialog: Boolean = true
    private var titleDialog: String? = null
    private var messageDialog: String? = null
    private var leftButtonDialog: String = "Yes"
    //    private var rightButtonDialog: String? = null
    private var onClickListenerDialog: OnClickListener? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
        //requestWindowFeature(android.view.Window.FEATURE_NO_TITLE)
        setCancelable(cancelableDialog)
        setContentView(R.layout.dialog_double_button)
//        val btnNegative = findViewById<Button>(R.id.btnNegative)
//        btnNegative.visibility = View.GONE
//        if (rightButtonDialog != null) {
//            btnNegative.visibility = View.VISIBLE
//            btnNegative.text = rightButtonDialog
//            btnNegative.setOnClickListener {
//                dismiss()
//                onClickListenerDialog?.onClickCancel()
//            }
//        }
        val btnPositive = findViewById<Button>(R.id.btnPositive)
        btnPositive.text = leftButtonDialog
        btnPositive.setOnClickListener {
            onClickListenerDialog?.onClick()
            dismiss()
        }
        (findViewById<TextView>(R.id.title)).text = titleDialog
        (findViewById<TextView>(R.id.message)).text = messageDialog
        super.onCreate(savedInstanceState)
    }

    constructor(
        context: Context, cancelableDialog: Boolean, titleDialog: String?,
        messageDialog: String, leftButtonDialog: String, /*rightButtonDialog: String?,*/
        onClickListenerDialog: OnClickListener
    ) : this(context) {
        this.cancelableDialog = cancelableDialog
        this.titleDialog = titleDialog
        this.messageDialog = messageDialog
        this.leftButtonDialog = leftButtonDialog
//        this.rightButtonDialog = rightButtonDialog
        this.onClickListenerDialog = onClickListenerDialog
    }
}


interface OnClickListener {
    //    fun onClickCancel()
    fun onClick()
}

In layout, we can create a dialog_double_button.xml

</shape>

In addition to above answers, If you are testing push notifications using FCM console, 'data' key and object is not added to Push Notification bundle. So you will not receive detailed push notification when App is background or killed.

In this case you have to opt for your back end admin console to test App background scenario.

Here, you will have added 'data' key to your push bundle. so, detailed push will be shown as expected. Hope this helps few.

Just use the shell script git-submodule-move.

1. Copy your backup .bak file in the following location of your pc : C:\Program Files\Microsoft SQL Server\MSSQL11.SQLEXPRESS\MSSQL\DATA
2. Connect to a server you want to store your DB
3. Right-click Database
4. Click Restore
5. Choose the Device radio button under the source section
6. Click Add.
7. Navigate to the path where your .bak file is stored, select it and click OK
8. Enter the destination of your DB
9. Enter the name by which you want to store your DB
10. Click OK

The above solutions missed out on where to keep your backup (.bak) file. This should do the trick. It worked for me.

WARNING: Security researches have found several poisoned packages on PyPI, including a package named urllib, which will 'phone home' when installed. If you used pip install urllib some time after June 2017, remove that package as soon as possible.

You can't, and you don't need to.

urllib2 is the name of the library included in Python 2. You can use the urllib.request library included with Python 3, instead. The urllib.request library works the same way urllib2 works in Python 2. Because it is already included you don't need to install it.

If you are following a tutorial that tells you to use urllib2 then you'll find you'll run into more issues. Your tutorial was written for Python 2, not Python 3. Find a different tutorial, or install Python 2.7 and continue your tutorial on that version. You'll find urllib2 comes with that version.

Alternatively, install the requests library for a higher-level and easier to use API. It'll work on both Python 2 and 3.

Within the package there is a class called JwtSecurityTokenHandler which derives from System.IdentityModel.Tokens.SecurityTokenHandler. In WIF this is the core class for deserialising and serialising security tokens.

The class has a ReadToken(String) method that will take your base64 encoded JWT string and returns a SecurityToken which represents the JWT.

The SecurityTokenHandler also has a ValidateToken(SecurityToken) method which takes your SecurityToken and creates a ReadOnlyCollection<ClaimsIdentity>. Usually for JWT, this will contain a single ClaimsIdentity object that has a set of claims representing the properties of the original JWT.

JwtSecurityTokenHandler defines some additional overloads for ValidateToken, in particular, it has a ClaimsPrincipal ValidateToken(JwtSecurityToken, TokenValidationParameters) overload. The TokenValidationParameters argument allows you to specify the token signing certificate (as a list of X509SecurityTokens). It also has an overload that takes the JWT as a string rather than a SecurityToken.

The code to do this is rather complicated, but can be found in the Global.asax.cx code (TokenValidationHandler class) in the developer sample called "ADAL - Native App to REST service - Authentication with ACS via Browser Dialog", located at

http://code.msdn.microsoft.com/AAL-Native-App-to-REST-de57f2cc

Alternatively, the JwtSecurityToken class has additional methods that are not on the base SecurityToken class, such as a Claims property that gets the contained claims without going via the ClaimsIdentity collection. It also has a Payload property that returns a JwtPayload object that lets you get at the raw JSON of the token. It depends on your scenario which approach it most appropriate.

The general (i.e. non JWT specific) documentation for the SecurityTokenHandler class is at

http://msdn.microsoft.com/en-us/library/system.identitymodel.tokens.securitytokenhandler.aspx

Depending on your application, you can configure the JWT handler into the WIF pipeline exactly like any other handler.

There are 3 samples of it in use in different types of application at

http://code.msdn.microsoft.com/site/search?f%5B0%5D.Type=SearchText&f%5B0%5D.Value=aal&f%5B1%5D.Type=User&f%5B1%5D.Value=Azure%20AD%20Developer%20Experience%20Team&f%5B1%5D.Text=Azure%20AD%20Developer%20Experience%20Team

Probably, one will suite your needs or at least be adaptable to them.

Apparently, the SSH server on Raspbian is now disabled by default. If there is no server listening for connections, it will not accept them. You can manually enable the SSH server according to this raspberrypi.org tutorial :

As of the November 2016 release, Raspbian has the SSH server disabled by default.

There are now multiple ways to enable it. Choose one:

From the desktop

1. Launch Raspberry Pi Configuration from the Preferences menu
2. Navigate to the Interfaces tab
3. Select Enabled next to SSH
4. Click OK

From the terminal with raspi-config

1. Enter sudo raspi-config in a terminal window
2. Select Interfacing Options
3. Navigate to and select SSH
4. Choose Yes
5. Select Ok
6. Choose Finish

Start the SSH service with systemctl

sudo systemctl enable ssh
sudo systemctl start ssh

On a headless Raspberry Pi

For headless setup, SSH can be enabled by placing a file named ssh, without any extension, onto the boot partition of the SD card. When the Pi boots, it looks for the ssh file. If it is found, SSH is enabled, and the file is deleted. The content of the file does not matter: it could contain text, or nothing at all.

Here's a partial solution using xml2. Breaking the solution up into smaller pieces generally makes it easier to ensure everything is lined up:

library(xml2)
data <- read_xml("http://forecast.weather.gov/MapClick.php?lat=29.803&lon=-82.411&FcstType=digitalDWML")

# Point locations
point <- data %>% xml_find_all("//point")
point %>% xml_attr("latitude") %>% as.numeric()
point %>% xml_attr("longitude") %>% as.numeric()

# Start time
data %>% 
  xml_find_all("//start-valid-time") %>% 
  xml_text()

# Temperature
data %>% 
  xml_find_all("//temperature[@type='hourly']/value") %>% 
  xml_text() %>% 
  as.integer()

Yes, use getJSONP. It's the only way to make cross domain/server async calls. (*Or it will be in the near future). Something like

$.getJSON('your-api-url/validate.php?'+$(this).serialize+'callback=?', function(data){
if(data)console.log(data);
});

The callback parameter will be filled in automatically by the browser, so don't worry.

On the server side ('validate.php') you would have something like this

<?php
if(isset($_GET))
{
//if condition is met
echo $_GET['callback'] . '(' . "{'message' : 'success', 'userID':'69', 'serial' : 'XYZ99UAUGDVD&orwhatever'}". ')';
}
else echo json_encode(array('error'=>'failed'));
?>

Try this instead:

SUM(CASE WHEN ValueDate > @startMonthDate THEN cash ELSE 0 END)

Explanation

Your CASE expression has incorrect syntax. It seems you are confusing the simple CASE expression syntax with the searched CASE expression syntax. See the documentation for CASE:

The CASE expression has two formats:

• The simple CASE expression compares an expression to a set of simple expressions to determine the result.
• The searched CASE expression evaluates a set of Boolean expressions to determine the result.

You want the searched CASE expression syntax:

CASE
     WHEN Boolean_expression THEN result_expression [ ...n ] 
     [ ELSE else_result_expression ] 
END

As a side note, if performance is an issue you may find that this expression runs more quickly if you rewrite using a JOIN and GROUP BY instead of using a dependent subquery.

Use

import Home from './layouts/Home'

rather than

import { Home } from './layouts/Home'

Remove {} from Home

The STL's philosophy is that you choose a container based on guarantees and not based on how the container is implemented. For example, your choice of container may be based on a need for fast lookups. For all you care, the container may be implemented as a unidirectional list -- as long as searching is very fast you'd be happy. That's because you're not touching the internals anyhow, you're using iterators or member functions for the access. Your code is not bound to how the container is implemented but to how fast it is, or whether it has a fixed and defined ordering, or whether it is efficient on space, and so on.

Built-in only python

Here is a pure python method for simple strings, left here for posterity.

def string2bits(s=''):
    return [bin(ord(x))[2:].zfill(8) for x in s]

def bits2string(b=None):
    return ''.join([chr(int(x, 2)) for x in b])

s = 'Hello, World!'
b = string2bits(s)
s2 = bits2string(b)

print 'String:'
print s

print '\nList of Bits:'
for x in b:
    print x

print '\nString:'
print s2

String:
Hello, World!

List of Bits:
01001000
01100101
01101100
01101100
01101111
00101100
00100000
01010111
01101111
01110010
01101100
01100100
00100001

String:
Hello, World!

my problem was that when connecting to SQL Database in the add reference wizard, to find the SERVERNAME. i found it by: running a query(SELECT @@SERVERNAME) inside SQL management studio and the reusl was my servername. I put that in my server name box and it worked all fine.

If you try using:

df[DATE_FIELD]=(pd.to_datetime(df[DATE_FIELD],***unit='s'***))

and receive an error :

"pandas.tslib.OutOfBoundsDatetime: cannot convert input with unit 's'"

This means the DATE_FIELD is not specified in seconds.

In my case, it was milli seconds - EPOCH time.

The conversion worked using below:

df[DATE_FIELD]=(pd.to_datetime(df[DATE_FIELD],unit='ms')) 

This is a standard problem.

Note that MySQL allows you to omit columns from the GROUP BY clause, which Standard SQL does not, but you do not get deterministic results in general when you use the MySQL facility.

SELECT *
  FROM Messages AS M
  JOIN (SELECT To_ID, From_ID, MAX(TimeStamp) AS Most_Recent
          FROM Messages
         WHERE To_ID = 12345678
         GROUP BY From_ID
       ) AS R
    ON R.To_ID = M.To_ID AND R.From_ID = M.From_ID AND R.Most_Recent = M.TimeStamp
 WHERE M.To_ID = 12345678

I've added a filter on the To_ID to match what you're likely to have. The query will work without it, but will return a lot more data in general. The condition should not need to be stated in both the nested query and the outer query (the optimizer should push the condition down automatically), but it can do no harm to repeat the condition as shown.

#fixedbutton {
    position: fixed;
    bottom: 0px;
    right: 0px; 
    z-index: 1000;
}

The z-index is added to overshadow any element with a greater property you might not know about.

Check your imports. There could be two classes with the same name. Either from your code or from a library you are using. Personally that was the issue.

Try this

CREATE FUNCTION [dbo].[CHARINDEX2] (
    @expressionToFind VARCHAR(MAX),
    @expressionToSearch VARCHAR(MAX),
    @occurrenceIndex INT,
    @startLocation INT = 0
)
RETURNS INT
AS BEGIN

IF @occurrenceIndex < 1 BEGIN
    RETURN CAST('The argument @occurrenceIndex must be a positive integer.' AS INT)
END

IF @startLocation < 0 BEGIN
    RETURN CAST('The argument @startLocation must be a non negative integer.' AS INT)
END

DECLARE @returnIndex INT

SET @returnIndex = CHARINDEX(@expressionToFind, @expressionToSearch, @startLocation)

IF (@occurrenceIndex = 1) BEGIN
    RETURN @returnIndex
END

DECLARE @target_length INT
SET @target_length = LEN(@expressionToFind)
SET @occurrenceIndex += -1

WHILE (@occurrenceIndex > 0 AND @returnIndex > 0) BEGIN
    SET @returnIndex = CHARINDEX(@expressionToFind, @expressionToSearch, @returnIndex + @target_length);
    SET @occurrenceIndex += -1
END

RETURN @returnIndex

END
GO

Looking at the dates for which it doesn't work -- those where the day is less than or equal to 12 -- I'm wondering whether it's parsing the dates as being in YYYY-DD-MM format?

There are certainly some weird characters (e.g. BOM) or some whitespace before the XML preamble (<?xml ...?>)?

Similar to @ernest-a's answer but without affecting $OLDPWD or define a new function you could fire a subshell (cd <path>; pwd)

$ pwd
/etc/apache2
$ cd ../cups 
$ cd -
/etc/apache2
$ (cd ~/..; pwd)
/Users
$ cd -
/etc/cups

This will get you the name of the day:

SELECT DATENAME(weekday, GETDATE())

1. Modify the definition of the function check_me as::

    function check_me(ev) {
   

2. Now you can access the methods and parameters of the event, in your case:

    ev.preventDefault();
   

3. Then, you have to pass the parameter on the onclick in the inline call::

    <button type="button" onclick="check_me(event);">Click Me!</button>
   

A useful link to understand this.

Full example:

<!DOCTYPE html>
<html lang="en">
  <head>
    <script type="text/javascript">
      function check_me(ev) {
        ev.preventDefault();
        alert("Hello World!")
      }
    </script>
  </head>
  <body>
    <button type="button" onclick="check_me(event);">Click Me!</button>
  </body>
</html>

Alternatives (best practices):

Although the above is the direct answer to the question (passing an event object to an inline event), there are other ways of handling events that keep the logic separated from the presentation

A. Using addEventListener:

<!DOCTYPE html>
<html lang="en">
  <head>
  </head>
  <body>
    <button id='my_button' type="button">Click Me!</button>

    <!-- put the javascript at the end to guarantee that the DOM is ready to use-->
    <script type="text/javascript">
      function check_me(ev) {
        ev.preventDefault();
        alert("Hello World!")
      }
      
      <!-- add the event to the button identified #my_button -->
      document.getElementById("my_button").addEventListener("click", check_me);
    </script>
  </body>
</html>

B. Isolating Javascript:

Both of the above solutions are fine for a small project, or a hackish quick and dirty solution, but for bigger projects, it is better to keep the HTML separated from the Javascript.

Just put this two files in the same folder:

• example.html:

<!DOCTYPE html>
<html lang="en">
  <head>
  </head>
  <body>
    <button id='my_button' type="button">Click Me!</button>

    <!-- put the javascript at the end to guarantee that the DOM is ready to use-->
    <script type="text/javascript" src="example.js"></script>
  </body>
</html>

• example.js:

function check_me(ev) {
    ev.preventDefault();
    alert("Hello World!")
}
document.getElementById("my_button").addEventListener("click", check_me);

jQuery uses a .call(...) method to assign the current node to this inside the function you pass as the parameter.

EDIT:

Don't be afraid to look inside jQuery's code when you have a doubt, it's all in clear and well documented Javascript.

ie: the answer to this question is around line 574,
callback.call( object[ name ], name, object[ name ] ) === false

Here is Java's way to find this information.

Windows: javap -v <class> | findstr major
Unix: javap -v <class> | grep major

For example:
> javap -v Application | findstr major   major version: 51

There are multiple answers to this question, partly due to ambiguous question - the title is talking about classes loaded by the JVM, whereas the contents of the question says "may or may not be loaded by the JVM".

Assuming that OP needs classes that are loaded by the JVM by a given classloader, and only those classes - my need as well - there is a solution (elaborated here) that goes like this:

import java.net.URL;
import java.util.Enumeration;
import java.util.Iterator;
import java.util.Vector;

public class CPTest {

    private static Iterator list(ClassLoader CL)
        throws NoSuchFieldException, SecurityException,
        IllegalArgumentException, IllegalAccessException {
        Class CL_class = CL.getClass();
        while (CL_class != java.lang.ClassLoader.class) {
            CL_class = CL_class.getSuperclass();
        }
        java.lang.reflect.Field ClassLoader_classes_field = CL_class
                .getDeclaredField("classes");
        ClassLoader_classes_field.setAccessible(true);
        Vector classes = (Vector) ClassLoader_classes_field.get(CL);
        return classes.iterator();
    }

    public static void main(String args[]) throws Exception {
        ClassLoader myCL = Thread.currentThread().getContextClassLoader();
        while (myCL != null) {
            System.out.println("ClassLoader: " + myCL);
            for (Iterator iter = list(myCL); iter.hasNext();) {
                System.out.println("\t" + iter.next());
            }
            myCL = myCL.getParent();
        }
    }

}

One of the neat things about it is that you can choose an arbitrary classloader you want to check. It is however likely to break should internals of classloader class change, so it is to be used as one-off diagnostic tool.

Change

Range(DataImportColumn & DataImportRow).Offset(0, 2).Value

to

Cells(DataImportRow,DataImportColumn).Value

When you just have the row and the column then you can use the cells() object. The syntax is Cells(Row,Column)

Also one more tip. You might want to fully qualify your Cells object. for example

ThisWorkbook.Sheets("WhatEver").Cells(DataImportRow,DataImportColumn).Value

You can also use the Ellipsis when specifying expected doctest output:

class MyClass(object):
    """Example of a doctest Ellipsis

    >>> thing = MyClass()
    >>> # Match <class '__main__.MyClass'> and <class '%(module).MyClass'>
    >>> type(thing)           # doctest:+ELLIPSIS
    <class '....MyClass'>
    """
    pass

Use mvn dependency:purge-local-repository -DactTransitively=false -Dskip=true if you have maven plugins as one of the modules. Otherwise Maven will try to recompile them, thus downloading the dependencies again.

Much of the Answer here seems to be hacks to the shape drawable, while android in itself supports this with the shapes functionality. This is something that worked perfectly for me.You can do this in two ways

Using a fixed height and width, that would stay the same regardless of the text that you put it as shown below

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">

<solid android:color="@color/alpha_white" />

    <size android:width="25dp" android:height="25dp"/>

<stroke android:color="@color/color_primary" android:width="1dp"/>

</shape>

Using Padding which re-adjusts the shape regardless of the text in the textview it as shown below

<solid android:color="@color/alpha_white" />

<padding
    android:bottom="@dimen/semi_standard_margin"
    android:left="@dimen/semi_standard_margin"
    android:right="@dimen/semi_standard_margin"
    android:top="@dimen/semi_standard_margin" />

<stroke android:color="@color/color_primary" android:width="2dp"/>

semi_standard_margin = 4dp

e.g.

 ColorTranslator.ToHtml(Color.FromArgb(Color.Tomato.ToArgb()))

This can avoid the KnownColor trick.

select dateadd(dd,360,getdate()) will give you correct date as shown below:

2017-09-30 15:40:37.260

I just ran the query and checked:

the best way to calculate the equation is simplified. That is, find the maximum divisor between two numbers and divide:

ex.

1920:1080 maximum common divisor 120 = 16:9
1024:768  maximum common divisor 256 = 4:3
1280:768  maximum common divisor 256 = 5:3

may happen also some approaches

public int compare(String v1, String v2) {
        v1 = v1.replaceAll("\\s", "");
        v2 = v2.replaceAll("\\s", "");
        String[] a1 = v1.split("\\.");
        String[] a2 = v2.split("\\.");
        List<String> l1 = Arrays.asList(a1);
        List<String> l2 = Arrays.asList(a2);


        int i=0;
        while(true){
            Double d1 = null;
            Double d2 = null;

            try{
                d1 = Double.parseDouble(l1.get(i));
            }catch(IndexOutOfBoundsException e){
            }

            try{
                d2 = Double.parseDouble(l2.get(i));
            }catch(IndexOutOfBoundsException e){
            }

            if (d1 != null && d2 != null) {
                if (d1.doubleValue() > d2.doubleValue()) {
                    return 1;
                } else if (d1.doubleValue() < d2.doubleValue()) {
                    return -1;
                }
            } else if (d2 == null && d1 != null) {
                if (d1.doubleValue() > 0) {
                    return 1;
                }
            } else if (d1 == null && d2 != null) {
                if (d2.doubleValue() > 0) {
                    return -1;
                }
            } else {
                break;
            }
            i++;
        }
        return 0;
    }

Have you tried your own code?
This should work:

SELECT * FROM people WHERE age BETWEEN x AND y

You can do it with the help of padding on a parent item, because relative padding (even height-wise) is based on the width of the parent element.

CSS:

.imageContainer {
    position: relative;
    width: 25%;
    padding-bottom: 25%;
    float: left;
    height: 0;
}

img {
    width: 100%;
    height: 100%;
    position: absolute;
    left: 0;
}

This is based on this article: Proportional scaling of responsive boxes using just CSS

Like Maiasaura, I prefer ggplot2. The transparent reference manual is one of the reasons. However, this is one quick way to get it done.

require(ggplot2)
data(diamonds)
qplot(carat, price, data = diamonds, colour = color)
# example taken from Hadley's ggplot2 book

And cause someone famous said, plot related posts are not complete without the plot, here's the result:

Here's a couple of references: qplot.R example, note basically this uses the same diamond dataset I use, but crops the data before to get better performance.

http://ggplot2.org/book/ the manual: http://docs.ggplot2.org/current/

I have started using IntelliJ IDEA Community Edition version 12.1.3 and I found the setting in the following place: -

File > Other Settings > Default Settings > {choose from Code Style dropdown}

The following (C#) code should do the trick

Uri uri = new Uri("http://www.mywebsite.com:80/pages/page1.aspx");
string requested = uri.Scheme + Uri.SchemeDelimiter + uri.Host + ":" + uri.Port;

I was getting this error too and the reason ended up being wrong call url. I am leaving this answer here, if someone else happens to mix the urls and getting this error. Took me hours to realize I had wrong URL.

Error I got (HTTP code 400):

{
    "error": "unsupported_grant_type",
    "error_description": "grant type not supported"
}

I was calling:

https://MY_INSTANCE.lightning.force.com

While the correct URL would have been:

https://MY_INSTANCE.cs110.my.salesforce.com

Once obtained, Access Tokens are typically sent along with every request from Clients to protected Resource Servers. This induce a risk for access token stealing and replay (assuming of course that access tokens are of type "Bearer" (as defined in the initial RFC6750).

Examples of those risks, in real life:

• Resource Servers generally are distributed application servers and typically have lower security levels compared to Authorization Servers (lower SSL/TLS config, less hardening, etc.). Authorization Servers on the other hand are usually considered as critical Security infrastructure and are subject to more severe hardening.

• Access Tokens may show up in HTTP traces, logs, etc. that are collected legitimately for diagnostic purposes on the Resource Servers or clients. Those traces can be exchanged over public or semi-public places (bug tracers, service-desk, etc.).

• Backend RS applications can be outsourced to more or less trustworthy third-parties.

The Refresh Token, on the other hand, is typically transmitted only twice over the wires, and always between the client and the Authorization Server: once when obtained by client, and once when used by client during refresh (effectively "expiring" the previous refresh token). This is a drastically limited opportunity for interception and replay.

Last thought, Refresh Tokens offer very little protection, if any, against compromised clients.

The problem is an expired intermediate certificate that is no longer used and must be deleted. Here is a blog post from Digicert explaining the issue and how to resolve it.

https://blog.digicert.com/expired-intermediate-certificate/

I was seeing the issue with Github not loading via SSL in both Safari and the command line with git pull. Once I deleted the old expired cert everything was fine.

I've come across Flexi Auth (http://haseydesign.com/flexi-auth/). It looks very promising, and I've started using it. It has wonderfful features. Fully integrates with CI, and comes with two different library files, in which one is very heavy loaded with all the functions and the other one contains only the validations.

One of the best is that the newly registered member gets temporary access for a given amount of time on the site, until they click on the link from their email and activate.

I would use ConfigurationManager.OpenMappedExeConfiguration.

Nevermind.

I had to look at the Lucene documentation. Seems I can use wildcards! :-)

I had the same problem on my mac, but in my case, the problem was that I did not run the database (sudo mongod) before; the problem was solved when I first ran the mondo sudod on the console and, once it was done, on another console, the connection to the server ...

About update#1, there are 2 problems :

• Number of days = 1 (d/MM/YYYY) instead of (dd/MM/YYYY)
• Empty date

here is the solution to avoid these problems :

jQuery.fn.dataTableExt.oSort['uk_date-asc'] = function (a, b) {
            var ukDatea = a.split('/');
            var ukDateb = b.split('/');

            //Date empty
             if (ukDatea[0] == "" || ukDateb[0] == "") return 1;

            //need to change Date (d/MM/YYYY) into Date (dd/MM/YYYY) 
            if(ukDatea[0]<10) ukDatea[0] = "0" + ukDatea[0]; 
            if(ukDateb[0]<10) ukDateb[0] = "0" + ukDateb[0];

            var x = (ukDatea[2] + ukDatea[1] + ukDatea[0]) * 1;
            var y = (ukDateb[2] + ukDateb[1] + ukDateb[0]) * 1;

            return ((x < y) ? -1 : ((x > y) ? 1 : 0));
        };

        //Sorting by Date 
        jQuery.fn.dataTableExt.oSort['uk_date-desc'] = function (a, b) {
            var ukDatea = a.split('/');
            var ukDateb = b.split('/');

             //Date empty
             if (ukDatea[0] == "" || ukDateb[0] == "") return 1;

            //MANDATORY to change Date (d/MM/YYYY) into Date (dd/MM/YYYY) 
            if(ukDatea[0]<10) ukDatea[0] = "0" + ukDatea[0]; 
            if(ukDateb[0]<10) ukDateb[0] = "0" + ukDateb[0];

            var x = (ukDatea[2] + ukDatea[1] + ukDatea[0]) * 1;
            var y = (ukDateb[2] + ukDateb[1] + ukDateb[0]) * 1;

            return ((x < y) ? 1 : ((x > y) ? -1 : 0));
        };

I really like stackPusher's ConvertToLetter function as a solution. However, in working with it I noticed several errors occurring at very specific inputs due to some flaws in the math. For example, inputting 392 returns 'N\', 418 returns 'O\', 444 returns 'P\', etc.

I reworked the function and the result produces the correct output for all input up to 703 (which is the first triple-letter column index, AAA).

Function ConvertToLetter2(iCol As Integer) As String
    Dim First As Integer
    Dim Second As Integer
    Dim FirstChar As String
    Dim SecondChar As String

    First = Int(iCol / 26)
    If First = iCol / 26 Then
        First = First - 1
    End If
    If First = 0 Then
        FirstChar = ""
    Else
        FirstChar = Chr(First + 64)
    End If

    Second = iCol Mod 26
    If Second = 0 Then
        SecondChar = Chr(26 + 64)
    Else
        SecondChar = Chr(Second + 64)
    End If

    ConvertToLetter2 = FirstChar & SecondChar

End Function

What is the difference between left join and left outer join?

Nothing. LEFT JOIN and LEFT OUTER JOIN are equivalent.

You can use the code from this minimal plugin. https://www.npmjs.com/package/paginator-js

Array.prototype.paginate = function(pageNumber, itemsPerPage){
  pageNumber   = Number(pageNumber)
  itemsPerPage = Number(itemsPerPage)
  pageNumber   = (pageNumber   < 1 || isNaN(pageNumber))   ? 1 : pageNumber
  itemsPerPage = (itemsPerPage < 1 || isNaN(itemsPerPage)) ? 1 : itemsPerPage

  var start     = ((pageNumber - 1) * itemsPerPage)
  var end       = start + itemsPerPage
  var loopCount = 0
  var result    = {
    data: [],
    end: false
  }

  for(loopCount = start; loopCount < end; loopCount++){
    this[loopCount] && result.data.push(this[loopCount]);
  }

  if(loopCount == this.length){
    result.end = true
  }

  return result
}

I know, it is long ago, but since the easiest answer was not yet posted I will do so for other user that might step by.

Just move the var inside the "name" block:

- name: Download apache
  vars:
    url: czxcxz
  shell: wget {{url}} 

And if you have lot insert queries but not wanna ger a ERROR message everytime , you can do it:

CREATE UNIQUE NONCLUSTERED INDEX SK01 ON dbo.Person(ID,Name,Active,PersonNumber) 
WITH(IGNORE_DUP_KEY = ON)

In case you need further info for your log/audit you can OUTPUT clause: This way, not only you keep the number of rows affected, but also what records.

As an example of the Output Clause during inserts: SQL Server list of insert identities

DECLARE @InsertedIDs table(ID int);

INSERT INTO YourTable
    OUTPUT INSERTED.ID
        INTO @InsertedIDs 
    SELECT ...

So I ran into the same problem when displaying portrait only modal views. Normally, I'd create a UINavigationController, set the viewController as the rootViewController, then display the UINavigationController as a modal view. But with iOS 6, the viewController will now ask the navigationController for its supported interface orientations (which, by default, is now all for iPad and everything but upside down for iPhone).

Solution: I had to subclass UINavigationController and override the autorotation methods. Kind of lame.

- (BOOL)shouldAutorotate {
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}
// pre-iOS 6 support 
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
    return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}

I came across this post searching how to add an extra directory for resources. I found a solution that may be useful to someone. Here is my final configuration to get that:

sourceSets {
    main {
        resources {
            srcDirs "src/main/resources", "src/main/configs"
        }
    }
}

A few differences:

1. print vs println:

   The print function prints messages in the Xcode console when debugging apps.

   The println is a variation of this that was removed in Swift 2 and is not used any more. If you see old code that is using println, you can now safely replace it with print.

   Back in Swift 1.x, print did not add newline characters at the end of the printed string, whereas println did. But nowadays, print always adds the newline character at the end of the string, and if you don't want it to do that, supply a terminator parameter of "".

2. NSLog:

   • NSLog adds a timestamp and identifier to the output, whereas print will not;

   • NSLog statements appear in both the device’s console and debugger’s console whereas print only appears in the debugger console.

   • NSLog in iOS 10-13/macOS 10.12-10.x uses printf-style format strings, e.g.

       NSLog("%0.4f", CGFloat.pi)
     

     that will produce:

     2017-06-09 11:57:55.642328-0700 MyApp[28937:1751492] 3.1416

   • NSLog from iOS 14/macOS 11 can use string interpolation. (Then, again, in iOS 14 and macOS 11, we would generally favor Logger over NSLog. See next point.)

   Nowadays, while NSLog still works, we would generally use “unified logging” (see below) rather than NSLog.

3. Effective iOS 14/macOS 11, we have Logger interface to the “unified logging” system. For an introduction to Logger, see WWDC 2020 Explore logging in Swift.

   • To use Logger, you must import os:

     import os
     

   • Like NSLog, unified logging will output messages to both the Xcode debugging console and the device console, too

   • Create a Logger and log a message to it:

     let logger = Logger(subsystem: Bundle.main.bundleIdentifier!, category: "network")
     logger.log("url = \(url)")
     

     When you observe the app via the external Console app, you can filter on the basis of the subsystem and category. It is very useful to differentiate your debugging messages from (a) those generated by other subsystems on behalf of your app, or (b) messages from other categories or types.

   • You can specify different types of logging messages, either .info, .debug, .error, .fault, .critical, .notice, .trace, etc.:

     logger.error("web service did not respond \(error.localizedDescription)")
     

     So, if using the external Console app, you can choose to only see messages of certain categories (e.g. only show debugging messages if you choose “Include Debug Messages” on the Console “Action” menu). These settings also dictate many subtle issues details about whether things are logged to disk or not. See WWDC video for more details.

   • By default, non-numeric data is redacted in the logs. In the example where you logged the URL, if the app were invoked from the device itself and you were watching from your macOS Console app, you would see the following in the macOS Console:

     url = <private>

     If you are confident that this message will not include user confidential data and you wanted to see the strings in your macOS console, you would have to do:

     os_log("url = \(url, privacy: .public)")
     

4. Prior to iOS 14/macOS 11, iOS 10/macOS 10.12 introduced os_log for “unified logging”. For an introduction to unified logging in general, see WWDC 2016 video Unified Logging and Activity Tracing.

   • Import os.log:

     import os.log
     

   • You should define the subsystem and category:

     let log = OSLog(subsystem: Bundle.main.bundleIdentifier!, category: "network")
     

     When using os_log, you would use a printf-style pattern rather than string interpolation:

     os_log("url = %@", log: log, url.absoluteString)
     

   • You can specify different types of logging messages, either .info, .debug, .error, .fault (or .default):

     os_log("web service did not respond", type: .error)
     

   • You cannot use string interpolation when using os_log. For example with print and Logger you do:

     logger.log("url = \(url)")
     

     But with os_log, you would have to do:

     os_log("url = %@", url.absoluteString)
     

   • The os_log enforces the same data privacy, but you specify the public visibility in the printf formatter (e.g. %{public}@ rather than %@). E.g., if you wanted to see it from an external device, you'd have to do:

     os_log("url = %{public}@", url.absoluteString)
     

   • You can also use the “Points of Interest” log if you want to watch ranges of activities from Instruments:

     let pointsOfInterest = OSLog(subsystem: Bundle.main.bundleIdentifier!, category: .pointsOfInterest)
     

     And start a range with:

     os_signpost(.begin, log: pointsOfInterest, name: "Network request")
     

     And end it with:

     os_signpost(.end, log: pointsOfInterest, name: "Network request")
     

     For more information, see https://stackoverflow.com/a/39416673/1271826.

Bottom line, print is sufficient for simple logging with Xcode, but unified logging (whether Logger or os_log) achieves the same thing but offers far greater capabilities.

The power of unified logging comes into stark relief when debugging iOS apps that have to be tested outside of Xcode. For example, when testing background iOS app processes like background fetch, being connected to the Xcode debugger changes the app lifecycle. So, you frequently will want to test on a physical device, running the app from the device itself, not starting the app from Xcode’s debugger. Unified logging lets you still watch your iOS device log statements from the macOS Console app.

PATH mode is used in generating XML from a SELECT query

1. SELECT   
       ID,  
       Name  
FROM temp1
FOR XML PATH;  

Ouput:
<row>
<ID>1</ID>
<Name>aaa</Name>
</row>

<row>
<ID>1</ID>
<Name>bbb</Name>
</row>

<row>
<ID>1</ID>
<Name>ccc</Name>
</row>

<row>
<ID>1</ID>
<Name>ddd</Name>
</row>

<row>
<ID>1</ID>
<Name>eee</Name>
</row>

The Output is element-centric XML where each column value in the resulting rowset is wrapped in an row element. Because the SELECT clause does not specify any aliases for the column names, the child element names generated are the same as the corresponding column names in the SELECT clause.

For each row in the rowset a tag is added.

2.
SELECT   
       ID,  
       Name  
FROM temp1
FOR XML PATH('');

Ouput:
<ID>1</ID>
<Name>aaa</Name>
<ID>1</ID>
<Name>bbb</Name>
<ID>1</ID>
<Name>ccc</Name>
<ID>1</ID>
<Name>ddd</Name>
<ID>1</ID>
<Name>eee</Name>

For Step 2: If you specify a zero-length string, the wrapping element is not produced.

3. 

    SELECT   

           Name  
    FROM temp1
    FOR XML PATH('');

    Ouput:
    <Name>aaa</Name>
    <Name>bbb</Name>
    <Name>ccc</Name>
    <Name>ddd</Name>
    <Name>eee</Name>

4. SELECT   
        ',' +Name  
FROM temp1
FOR XML PATH('')

Ouput:
,aaa,bbb,ccc,ddd,eee

In Step 4 we are concatenating the values.

5. SELECT ID,
    abc = (SELECT   
            ',' +Name  
    FROM temp1
    FOR XML PATH('') )
FROM temp1

Ouput:
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee


6. SELECT ID,
    abc = (SELECT   
            ',' +Name  
    FROM temp1
    FOR XML PATH('') )
FROM temp1 GROUP by iD

Ouput:
ID  abc
1   ,aaa,bbb,ccc,ddd,eee

In Step 6 we are grouping the date by ID.

STUFF( source_string, start, length, add_string ) Parameters or Arguments source_string The source string to modify. start The position in the source_string to delete length characters and then insert add_string. length The number of characters to delete from source_string. add_string The sequence of characters to insert into the source_string at the start position.

SELECT ID,
    abc = 
    STUFF (
        (SELECT   
                ',' +Name  
        FROM temp1
        FOR XML PATH('')), 1, 1, ''
    )
FROM temp1 GROUP by iD

Output:
-----------------------------------
| Id        | Name                |
|---------------------------------|
| 1         | aaa,bbb,ccc,ddd,eee |
-----------------------------------

echo : echo is a language construct where there is not required to use parentheses with it and it can take any number of parameters and return void.

   void echo (param1,param2,param3.....);

   Example: echo "test1","test2,test3";

print : it is a language construct where there is not required to use parentheses it just take one parameter and return

    1 always.

           int print(param1);

           print "test1";
           print "test1","test2"; // It will give syntax error

prinf : It is a function which takes atleast one string and format style and returns length of output string.

    int printf($string,$s);

    $s= "Shailesh";
    $i= printf("Hello %s how are you?",$s);    
    echo $i;

    Output : Hello Shailesh how are you?
             27



   echo returns void so its execution is faster than print and printf

The following script solved my problem:

// Fake localStorage implementation. 
// Mimics localStorage, including events. 
// It will work just like localStorage, except for the persistant storage part. 

var fakeLocalStorage = function() {
  var fakeLocalStorage = {};
  var storage; 

  // If Storage exists we modify it to write to our fakeLocalStorage object instead. 
  // If Storage does not exist we create an empty object. 
  if (window.Storage && window.localStorage) {
    storage = window.Storage.prototype; 
  } else {
    // We don't bother implementing a fake Storage object
    window.localStorage = {}; 
    storage = window.localStorage; 
  }

  // For older IE
  if (!window.location.origin) {
    window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
  }

  var dispatchStorageEvent = function(key, newValue) {
    var oldValue = (key == null) ? null : storage.getItem(key); // `==` to match both null and undefined
    var url = location.href.substr(location.origin.length);
    var storageEvent = document.createEvent('StorageEvent'); // For IE, http://stackoverflow.com/a/25514935/1214183

    storageEvent.initStorageEvent('storage', false, false, key, oldValue, newValue, url, null);
    window.dispatchEvent(storageEvent);
  };

  storage.key = function(i) {
    var key = Object.keys(fakeLocalStorage)[i];
    return typeof key === 'string' ? key : null;
  };

  storage.getItem = function(key) {
    return typeof fakeLocalStorage[key] === 'string' ? fakeLocalStorage[key] : null;
  };

  storage.setItem = function(key, value) {
    dispatchStorageEvent(key, value);
    fakeLocalStorage[key] = String(value);
  };

  storage.removeItem = function(key) {
    dispatchStorageEvent(key, null);
    delete fakeLocalStorage[key];
  };

  storage.clear = function() {
    dispatchStorageEvent(null, null);
    fakeLocalStorage = {};
  };
};

// Example of how to use it
if (typeof window.localStorage === 'object') {
  // Safari will throw a fit if we try to use localStorage.setItem in private browsing mode. 
  try {
    localStorage.setItem('localStorageTest', 1);
    localStorage.removeItem('localStorageTest');
  } catch (e) {
    fakeLocalStorage();
  }
} else {
  // Use fake localStorage for any browser that does not support it.
  fakeLocalStorage();
}

It checks if localStorage exists and can be used and in the negative case, it creates a fake local storage and uses it instead of the original localStorage. Please let me know if you need further information.

Your'e almost there, you just need to get the properties from the type, rather than expect the properties to be accessible in the form of a collection or property bag:

var property in obj.GetType().GetProperties()

From there you can access like so:

property.Name
property.GetValue(obj, null)

With GetValue the second parameter will allow you to specify index values, which will work with properties returning collections - since a string is a collection of chars, you can also specify an index to return a character if needs be.

For me, I had //= require jquery after //= require bootstrap. Once I moved jquery before bootstrap, everything worked.

Combining the previous answers provides these solutions:

if (typeof str == 'string' || str instanceof String)

or

Object.prototype.toString.call(str) == '[object String]'

Since nobody has added the obvious solution yet which works fine for two comparisons, I'll offer it:

if (foobar === foo || foobar === bar) {
     //do something
}

And, if you have lots of values (perhaps hundreds or thousands), then I'd suggest making a Set as this makes very clean and simple comparison code and it's fast at runtime:

// pre-construct the Set
var tSet = new Set(["foo", "bar", "test1", "test2", "test3", ...]);

// test the Set at runtime
if (tSet.has(foobar)) {
    // do something
}

For pre-ES6, you can get a Set polyfill of which there are many. One is described in this other answer.

The best option is to clone them with clone() method.

One thing missing here: if you have a varying number of elements that you want to put together to something like

WHERE [...] AND (field LIKE '%abc%' OR field LIKE '%def%')

and dont want to assemble a DQL-String yourself, you can use the orX mentioned above like this:

$patterns = ['abc', 'def'];
$orStatements = $qb->expr()->orX();
foreach ($patterns as $pattern) {
    $orStatements->add(
        $qb->expr()->like('field', $qb->expr()->literal('%' . $pattern . '%'))
    );
}
$qb->andWhere($orStatements);

Create a C# class that maps to your Json and use Newsoft JsonConvert to Deserialise it.

For example:

public Class MyResponse
{
    public Meta Meta { get; set; }
    public Response Response { get; set; }
}

If you want to use Java 8 NIO API, the following program will print the size, in bytes, of the directory it is located in.

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class PathSize {

    public static void main(String[] args) {
        Path path = Paths.get(".");
        long size = calculateSize(path);
        System.out.println(size);
    }

    /**
     * Returns the size, in bytes, of the specified <tt>path</tt>. If the given
     * path is a regular file, trivially its size is returned. Else the path is
     * a directory and its contents are recursively explored, returning the
     * total sum of all files within the directory.

}

The calculateSize method is universal for Path objects, so it also works for files. Note that if a file or directory is inaccessible, in this case the returned size of the path object will be 0.

If you don't want to have to know the serial name of your device for adb -s emulator-5554 emu kill, then you can just use adb -e emu kill to kill a single emulator. This won't kill anything if you have more than one emulator running at once, but it's useful for automation where you start and stop a single emulator for a test.

In Short

android:id="@+id/my_button"

+id Plus sign tells android to add or create a new id in Resources.

while

android:layout_below="@id/my_button"

it just help to refer the already generated id..

I can think of different method to achieve the same

IList<SelectableEnumItem> result= array;

or (i had some situation that this one didn't work well)

var result = (List<SelectableEnumItem>) array;

or use linq extension

var result = array.CastTo<List<SelectableEnumItem>>();

or

var result= array.Select(x=> x).ToArray<SelectableEnumItem>();

or more explictly

var result= array.Select(x=> new SelectableEnumItem{FirstName= x.Name, Selected = bool.Parse(x.selected) });

please pay attention in above solution I used dynamic Object

I can think of some more solutions that are combinations of above solutions. but I think it covers almost all available methods out there.

Myself I use the first one

Well, this is your chance! It looks like PDO is ready; use that instead.

You have to do it for each of your table.

Then export your schema :

Check Generate INSERT statements for table

It is okay !

Perfectly described here https://www.smashingmagazine.com/2014/05/moving-git-repository-new-server/

First, we have to fetch all of the remote branches and tags from the existing repository to our local index:

git fetch origin

We can check for any missing branches that we need to create a local copy of:

git branch -a

Let’s use the SSH-cloned URL of our new repository to create a new remote in our existing local repository:

git remote add new-origin [email protected]:manakor/manascope.git

Now we are ready to push all local branches and tags to the new remote named new-origin:

git push --all new-origin 
git push --tags new-origin

Let’s make new-origin the default remote:

git remote rm origin

Rename new-origin to just origin, so that it becomes the default remote:

git remote rename new-origin origin

If you are still recieving the InvalidKeyException when running my AES encryption program with 256 bit keys, but not with 128 bit keys, it is because you have not installed the new policy JAR files correctly, and has nothing to do with BouncyCastle (which is also restrained by those policy files). Try uninstalling, then re-installing java and then replaceing the old jar's with the new unlimited strength ones. Other than that, I'm out of ideas, best of luck.

You can see the policy files themselves if you open up the lib/security/local_policy.jar and US_export_policy.jar files in winzip and look at the conatined *.policy files in notepad and make sure they look like this:

default_local.policy:

    // Country-specific policy file for countries with no limits on crypto strength.
grant {
    // There is no restriction to any algorithms.
    permission javax.crypto.CryptoAllPermission; 
};

default_US_export.policy:

// Manufacturing policy file.
grant {
    // There is no restriction to any algorithms.
    permission javax.crypto.CryptoAllPermission; 
};

When using JavaScript to access an HTML element, there is a good chance that the element is not on the page and therefore not in the dom as far as JavaScript is concerned, when the code to access that element runs.

This problem can occur even though you can visually see the HTML element in the browser window or have the code set to be called in the onload method.

I ran into this problem after writing code to repopulate specific div elements on a page after retrieving the cookies.

What is apparently happening is that even though the HTML has loaded and is outputted by the browser, the JavaScript code is running before the page has completed loading.

The solution to this problem which just may be a JavaScript bug, is to place the code you want to run within a timer that delays the code run by 400 milliseconds or so. You will need to test it to determine how quick you can run the code.

I also made a point to test for the element before attempting to assign values to it.

window.setTimeout(function() { if( document.getElementById("book") ) { // Code goes here }, 400 /* but after 400 ms */);

This may or may not help you solve your problem, but keep this in mind and understand that browsers do not always function as expected.

//Javascript file 1

localStorage.setItem('Data',10);

//Javascript file 2

var number=localStorage.getItem('Data');

Don't forget to link your JS files in html :)

You are inserting not Updating the result. You can define the name column in primary column or set it is unique.

You may also try to check the version of the Oracle jdbc driver and Oracle database. Just today I had this issue when using ojdbc6.jar (version 11.2.0.3.0) to connect to an Oracle 9.2.0.4.0 server. Replacing it with ojdbc6.jar version 11.1.0.7.0 solved the issue.

I also managed to make ojdbc6.jar version 11.2.0.3.0 connect without error, by adding oracle.jdbc.timezoneAsRegion=false in file oracle/jdbc/defaultConnectionProperties.properties (inside the jar). Found this solution here (broken link)

Then, one can add -Doracle.jdbc.timezoneAsRegion=false to the command line, or AddVMOption -Doracle.jdbc.timezoneAsRegion=false in config files that use this notation.

You can also do this programmatically, e.g. with System.setProperty.

In some cases you can add the environment variable on a per-connection basis if that's allowed (SQL Developer allows this in the "Advanced" connection properties; I verified it to work when connecting to a database that doesn't have the problem and using a database link to a database which has).

I was facing same issue I have resolved it by removing a field name which was used twice on ajax e.g

    jQuery.ajax({
    url : '/search-result',
    data : {
      searchField : searchField,
      searchFieldValue : searchField,
      nid    :  nid,
      indexName : indexName,
      indexType : indexType
    },
.....

If you have LINQ:

var itemtoremove = prods.Where(item => item.ID == 1).First();
prods.Remove(itemtoremove)

That site makes use of the "fragment" part of a url: the stuff after the "#". This is not sent to the server by the browser as part of the GET request, but can be used to store page state. So yes you can change the fragment without causing a page refresh or reload. When the page loads, your javascript reads this fragment and updates the page content appropriately, fetching data from the server via ajax requests as required. To read the fragment in js:

var fragment = location.hash;

but note that this value will include the "#" character at the beginning. To set the fragment:

location.hash = "your_state_data";

It is because Ajax is asynchronous, the success or the error function will be called later, when the server answer the client. So, just move parts depending on the result into your success function like that :

jQuery.ajax({

            type:"post",
            dataType:"json",
            url: myAjax.ajaxurl,
            data: {action: 'submit_data', info: info},
            success: function(data) {
                successmessage = 'Data was succesfully captured';
                $("label#successmessage").text(successmessage);
            },
            error: function(data) {
                successmessage = 'Error';
                $("label#successmessage").text(successmessage);
            },
        });

        $(":input").val('');
        return false;

I encountered a similar error. The mistake I made was to use the "controller" name as "Pages" instead of "pages" in my url.

There is a easy solution for that problem, the solution is removed the certificate the yours Keychain, the previous thing will cause that it asks again to the user and password.

Steps:

1. Open keychain access

2. Search the certificate gitHub.com.

3. Remove gitHub.com certificate.

4. Execute any operation with git in your terminal. this again ask your username and password.

For Windows Users find the key chain by following:

Control Panel >> User Account >> Credential Manager >> Windows Credential >> Generic Credential

Following looks very simple to me:

model.layers[idx].output

Above is a tensor object, so you can modify it using operations that can be applied to a tensor object.

For example, to get the shape model.layers[idx].output.get_shape()

idx is the index of the layer and you can find it from model.summary()

Depends on the database server. MySQL doesn't care, its basically the same thing.

Oracle, DB2, and other enterprise level database solutions make a distinction. Usually a schema is a collection of tables and a Database is a collection of schemas.

import sqlite3

db = sqlite3.connect('mydatabase.db')
cursor = db.execute('SELECT * FROM students ORDER BY CREATE_AT')
studentList = cursor.fetchall()

columnNames = list(map(lambda x: x[0], cursor.description)) #students table column names list
studentsAssoc = {} #Assoc format is dictionary similarly


#THIS IS ASSOC PROCESS
for lineNumber, student in enumerate(studentList):
    studentsAssoc[lineNumber] = {}

    for columnNumber, value in enumerate(student):
        studentsAssoc[lineNumber][columnNames[columnNumber]] = value


print(studentsAssoc)

The result is definitely true, but I do not know the best.

I followed configparser approach and it worked quite well for me. Created one PropertyReader file and used config parser there to ready property to corresponding to each section.

**Used Python 2.7

Content of PropertyReader.py file:

#!/usr/bin/python
import ConfigParser

class PropertyReader:

def readProperty(self, strSection, strKey):
    config = ConfigParser.RawConfigParser()
    config.read('ConfigFile.properties')
    strValue = config.get(strSection,strKey);
    print "Value captured for "+strKey+" :"+strValue
    return strValue

Content of read schema file:

from PropertyReader import *

class ReadSchema:

print PropertyReader().readProperty('source1_section','source_name1')
print PropertyReader().readProperty('source2_section','sn2_sc1_tb')

Content of .properties file:

[source1_section]
source_name1:module1
sn1_schema:schema1,schema2,schema3
sn1_sc1_tb:employee,department,location
sn1_sc2_tb:student,college,country

[source2_section]

sn2_schema:schema4,schema5,schema6
sn2_sc1_tb:employee,department,location
sn2_sc2_tb:student,college,country

My immediate solution (since I couldn't find the ASP.NET worker process) was to give write (that is, Modify) permission to IIS_IUSRS. This worked. I seem to recall that in WinXP I had to specifically given the ASP.NET worker process write permission to accomplish this. Maybe my memory is faulty, but anyway...

@DraganRadivojevic wrote that he thought this was dangerous from a security viewpoint. I do not disagree, but since this was my workstation and not a network server, it seemed relatively safe. In any case, his answer is better and is what I finally settled on after chasing down a fail-path due to not specifying the correct domain for the AppPool user.

just add /FORCE as linker flag and you're all set.

for instance, if you're working on CMakeLists.txt. Then add following line:

SET(CMAKE_EXE_LINKER_FLAGS  "/FORCE")

the name of the the test case for class Foo should be FooTestCase or something like it (FooIntegrationTestCase or FooAcceptanceTestCase) - since it is a test case. see http://xunitpatterns.com/ for some standard naming conventions like test, test case, test fixture, test method, etc.

 txtText.Font = new Font("Segoe UI", 8,FontStyle.Bold);
 //Font(Font Name,Font Size,Font.Style)

I guess you could use curl and wget, but since Oracle requires you to check of some checkmarks this will be painfull to emulate with the tools mentioned. You would have to download the page with the license agreement and from looking at it figure out what request is needed to get to the actual download.

Of course you could simply start a browser, but this might not qualify as 'from the command line'. So you might want to look into lynx, a text based browser.

You want the (standard) POSIXt type from base R that can be had in 'compact form' as a POSIXct (which is essentially a double representing fractional seconds since the epoch) or as long form in POSIXlt (which contains sub-elements).

R> now

R> now + 10  # adds 10 seconds
[1] "2009-12-25 18:39:21 CST"
R> as.POSIXlt(now)
[1] "2009-12-25 18:39:11 CST"
R> str(as.POSIXlt(now))
 POSIXlt[1:9], format: "2009-12-25 18:39:11"
R> unclass(as.POSIXlt(now))

There is a much easier way to run Java, no configuration needed:

1. Install the Code Runner Extension
2. Open your Java code file in Text Editor, then use shortcut Ctrl+Alt+N, or press F1 and then select/type Run Code, or right click the Text Editor and then click Run Code in context menu, the code will be compiled and run, and the output will be shown in the Output Window.

If you have a text file with loads of packages you need to add the -r flag

pip install --upgrade --no-deps --force-reinstall -r requirements.txt

The easiest solution working fine for me is this:

export CFLAGS=-ggdb
export CXXFLAGS=-ggdb

CMake will append them to all configurations' flags. Just make sure to clear CMake cache.

I have found it best to add viewBox and preserveAspectRatio attributes to my SVGs. The viewbox should describe the full width and height of the SVG in the form 0 0 w h:

<svg preserveAspectRatio="xMidYMid meet" viewBox="0 0 700 550"></svg>

You need to re-factor the code into pieces. This doesn't stop execution, it just puts a delay in between the parts.

function partA() {
  ...
  window.setTimeout(partB,1000);
}

function partB() {
   ...
}

This because a char is stored at all effects as a 8-bit number. Speaking about a negative or positive char doesn't make sense if you consider it an ASCII code (which can be just signed*) but makes sense if you use that char to store a number, which could be in range 0-255 or in -128..127 according to the 2-complement representation.

*: it can be also unsigned, it actually depends on the implementation I think, in that case you will have access to extended ASCII charset provided by the encoding used

i use colname(train) = paste("A", colname(train)) and it turns out to the same problem as yours.

I finally figure out that randomForest is more stingy than rpart, it can't recognize the colname with space, comma or other specific punctuation.

paste function will prepend "A" and " " as seperator with each colname. so we need to avert the space and use this sentence instead:

colname(train) = paste("A", colname(train), sep = "")

this will prepend string without space.

check this, its guaranteed and easy !

Below code works for me

first I defined the partnerTypesMap like below in the server side,

Map<String, String> partnerTypes = new HashMap<>();

after adding values to it I added the object to model,

model.addAttribute("partnerTypesMap", partnerTypes);

When rendering the page I use below foreach to print them one by one.

<c:forEach items="${partnerTypesMap}" var="partnerTypesMap">
      <form:option value="${partnerTypesMap['value']}">${partnerTypesMap['key']}</form:option>
</c:forEach>

$('myObject').css({'background-image': 'url(imgUrl)',});

npos is just a token value that tells you that find() did not find anything (probably -1 or something like that). find() checks for the first occurence of the parameter, and returns the index at which the parameter begins. For Example,

  string name = "asad.txt";
  int i = name.find(".txt");
  //i holds the value 4 now, that's the index at which ".txt" starts
  if (i==string::npos) //if ".txt" was NOT found - in this case it was, so  this condition is false
    name.append(".txt");

DO $$
DECLARE tableId integer;
BEGIN
  INSERT INTO Table1 (name) VALUES ('a_title') RETURNING id INTO tableId;
  INSERT INTO Table2 (val) VALUES (tableId);

Here is where you went wrong:

this.result = http.get('friends.json')
                  .map(response => response.json())
                  .subscribe(result => this.result =result.json());

it should be:

http.get('friends.json')
                  .map(response => response.json())
                  .subscribe(result => this.result =result);

or

http.get('friends.json')
                  .subscribe(result => this.result =result.json());

You have made two mistakes:

1- You assigned the observable itself to this.result. When you actually wanted to assign the list of friends to this.result. The correct way to do it is:

• you subscribe to the observable. .subscribe is the function that actually executes the observable. It takes three callback parameters as follow:

  .subscribe(success, failure, complete);

for example:

.subscribe(
    function(response) { console.log("Success Response" + response)},
    function(error) { console.log("Error happened" + error)},
    function() { console.log("the subscription is completed")}
);

Usually, you take the results from the success callback and assign it to your variable. the error callback is self explanatory. the complete callback is used to determine that you have received the last results without any errors. On your plunker, the complete callback will always be called after either the success or the error callback.

2- The second mistake, you called .json() on .map(res => res.json()), then you called it again on the success callback of the observable. .map() is a transformer that will transform the result to whatever you return (in your case .json()) before it's passed to the success callback you should called it once on either one of them.

You might want to change the DNS settings of the Docker daemon. You can edit (or create) the configuration file at /etc/docker/daemon.json with the dns key, as

{
    "dns": ["your_dns_address", "8.8.8.8"]
}

In the example above, the first element of the list is the address of your DNS server. The second item is the Google’s DNS which can be used when the first one is not available.

Before proceeding, save daemon.json and restart the docker service.

sudo service docker restart

Once fixed, retry to run the build command.

To specify any additional asset folder I've used this with my Gradle. This adds moreAssets, a folder in the project root, to the assets.

android {
    sourceSets {
        main.assets.srcDirs += '../moreAssets'
    }
