Found a way to grant Windows Service access to Network Drive.

Take Windows Server 2012 with NFS Disk for example:

Step 1: Write a Batch File to Mount.

Write a batch file, ex: C:\mount_nfs.bat

echo %time% >> c:\mount_nfs_log.txt
net use Z: \\{your ip}\{netdisk folder}\ >> C:\mount_nfs_log.txt 2>&1

Step 2: Mount Disk as NT AUTHORITY/SYSTEM.

Open "Task Scheduler", create a new task:

1. Run as "SYSTEM", at "System Startup".
2. Create action: Run "C:\mount_nfs.bat".

After these two simple steps, my Windows ActiveMQ Service run under "Local System" priviledge, perform perfectly without login.

With PowerShell 5.1 in Windows 10 you can use:

Get-SmbMapping | Remove-SmbMapping -Confirm:$false

This question has been answered already, but since there is a more convenient way to get the UNC path and some more I recommend using Path Copy, which is free and you can practically get any path you want with one click:

https://pathcopycopy.github.io/

Here is a screenshot demonstrating how it works. The latest version has more options and definitely UNC Path too:

It may be that the Windows Credential Manager is holding onto credentials for the network share.

Load up Credential Manager (the easiest way is perhaps just to Search for that in the Start Menu), see if there are any Windows Credentials for your network share, and try deleting/updating them.

this is a example code copied from https://en.wikipedia.org/wiki/User:Evercat/Buddhabrot.c

I just want to echo sam9046's modest comment as an alternative and potentially much easier solution that worked in my case: uninstall and install homebrew again from scratch. No sudo commands required.

You can also browse/modify the uninstall script from that link above if you need to ensure it won't affect your previously installed packages. In my case this was just my home machine so I just started over.

If you're not doing the else, why not do:

if (x==2) doSomething();

Use ajax, a simple example,

HTML

<button id="button">Get Data</button>

Javascript

var button = document.getElementById("button");

button.addEventListener("click" ajaxFunction, false);

var ajaxFunction = function () {
    // ajax code here
}

Alternatively look into jquery ajax http://api.jquery.com/jQuery.ajax/

You may like lfqueue, https://github.com/Taymindis/lfqueue. It’s lock free concurrent queue. I’m currently using it to consuming the queue from multiple incoming calls and works like a charm.

As I found best and suitable option for me and it will work with animation too.

You can use indicator it self as a background.

You can set app:tabIndicatorGravity="stretch" attribute to use as background.

Example:

   <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabIndicatorGravity="stretch"
        app:tabSelectedTextColor="@color/white"
        app:tabTextColor="@color/colorAccent">

        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Chef" />


        <android.support.design.widget.TabItem
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="User" />

    </android.support.design.widget.TabLayout>

Hope it will helps you.

Here is the utility I wrote to generate a simple setup.py file (template) with useful comments and links. I hope, it will be useful.

Installation

sudo pip install setup-py-cli

Usage

To generate setup.py file just type in the terminal.

setup-py

Now setup.py file should occur in the current directory.

Generated setup.py

from distutils.core import setup
from setuptools import find_packages
import os


# User-friendly description from README.md
current_directory = os.path.dirname(os.path.abspath(__file__))
try:
    with open(os.path.join(current_directory, 'README.md'), encoding='utf-8') as f:
        long_description = f.read()
except Exception:
    long_description = ''

setup(
    # Name of the package
    name=<name of current directory>,

    # Packages to include into the distribution
    packages=find_packages('.'), 

    # Start with a small number and increase it with every change you make
    # https://semver.org
    version='1.0.0',

    # Chose a license from here: https://help.github.com/articles/licensing-a-repository
    # For example: MIT
    license='',

    # Short description of your library
    description='',

    # Long description of your library
    long_description = long_description,
    long_description_context_type = 'text/markdown',

    # Your name
    author='', 

    # Your email
    author_email='',     

    # Either the link to your github or to your website
    url='',

    # Link from which the project can be downloaded
    download_url='',

    # List of keyword arguments
    keywords=[],

    # List of packages to install with this one
    install_requires=[],

    # https://pypi.org/classifiers/
    classifiers=[]  
)

Content of the generated setup.py:

• automatically fulfilled package name based on the name of the current directory.
• some basic fields to fulfill.
• clarifying comments and links to useful resources.
• automatically inserted description from README.md or an empty string if there is no README.md.

Here is the link to the repository. Fill free to enhance the solution.

There is no such function; the easiest way to do this is to use a dict comprehension:

my_dictionary = {k: f(v) for k, v in my_dictionary.items()}

In python 2.7, use the .iteritems() method instead of .items() to save memory. The dict comprehension syntax wasn't introduced until python 2.7.

Note that there is no such method on lists either; you'd have to use a list comprehension or the map() function.

As such, you could use the map() function for processing your dict as well:

my_dictionary = dict(map(lambda kv: (kv[0], f(kv[1])), my_dictionary.iteritems()))

but that's not that readable, really.

This regular expression matches anything that isn't a letter, digit, or an underscore (_) character.

\W

For example in JavaScript:

"(,,@,£,() asdf 345345".replace(/\W/g, ' '); // Output: "          asdf 345345"

With SQL server you can just use a CTE instead of IF/THEN logic to make it easy to map from your existing queries and change the number of involved queries;

WITH cte AS (
    SELECT product,price,1 a FROM table1 WHERE project=1   UNION ALL
    SELECT product,price,2 a FROM table1 WHERE customer=2  UNION ALL
    SELECT product,price,3 a FROM table1 WHERE company=3
)
SELECT TOP 1 WITH TIES product,price FROM cte ORDER BY a;

An SQLfiddle to test with.

Alternately, you can combine it all into one SELECT to simplify it for the optimizer;

SELECT TOP 1 WITH TIES product,price FROM table1 
WHERE project=1 OR customer=2 OR company=3
ORDER BY CASE WHEN project=1  THEN 1 
              WHEN customer=2 THEN 2
              WHEN company=3  THEN 3 END;

Another SQLfiddle.

Not sure whether it would help you or not but it works to me:

l = ["a", "b", "c", "d", "e"]
outRes = dict((l[i], l[i+1]) if i+1 < len(l) else (l[i], '') for i in xrange(len(l)))

High-Level Design (HLD) involves decomposing a system into modules, and representing the interfaces & invocation relationships among modules. An HLD is referred to as software architecture.

LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.

Now, HLD and LLD are actually used in traditional Approach (Function-Oriented Software Design) whereas, in OOAD, the system is seen as a set of objects interacting with each other.

As per the above definitions, a high-level design document will usually include a high-level architecture diagram depicting the components, interfaces, and networks that need to be further specified or developed. The document may also depict or otherwise refer to work flows and/or data flows between component systems.

Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module. The LLD will contain - a detailed functional logic of the module in pseudo code - database tables with all elements including their type and size - all interface details with complete API references(both requests and responses) - all dependency issues - error message listings - complete inputs and outputs for a module.

Selects are slow and unnescsaary. The following code will be far faster:

Sub CopyRowsAcross() 
Dim i As Integer 
Dim ws1 As Worksheet: Set ws1 = ThisWorkbook.Sheets("Sheet1") 
Dim ws2 As Worksheet: Set ws2 = ThisWorkbook.Sheets("Sheet2") 

For i = 2 To ws1.Range("B65536").End(xlUp).Row 
    If ws1.Cells(i, 2) = "Your Critera" Then ws1.Rows(i).Copy ws2.Rows(ws2.Cells(ws2.Rows.Count, 2).End(xlUp).Row + 1) 
Next i 
End Sub 

Simply you can define a class in your css file and cascade it into html file like

<i class="fa fa-plus fa-lg green"></i> 

now write down in css

.green{ color:green}

You can use .is().

if( $('#leftmenu').is(':empty') ) {

Or you could just test the length property to see if one was found:

if( $('#leftmenu:empty').length ) {

You can use $.trim() to remove whitespace (if that's what you want) and check for the length of the content.

if( !$.trim( $('#leftmenu').html() ).length ) {

If you use ios simulator you can open system console log on MAC

? + space and type "console" -> press "Enter" to open system console log then select your simulator

Hibernate, because it:

• is stable - being around for so many years, it lacks any major problems
• dictates the standards in the ORM field
• implements the standard (JPA), in addition to dictating it.
• has tons of information about it on the Internet. There are many tutorials, common problem solutions, etc
• is powerful - you can translate a very complex object model into a relational model.
• it has support for any major and medium RDBMS
• is easy to work with, once you learn it well

A few points on why (and when) to use ORM:

• you work with objects in your system (if your system has been designed well). Even if using JDBC, you will end up making some translation layer, so that you transfer your data to your objects. But my bets are that hibernate is better at translation than any custom-made solution.
• it doesn't deprive you of control. You can control things in very small details, and if the API doesn't have some remote feature - execute a native query and you have it.
• any medium-sized or bigger system can't afford having one ton of queries (be it at one place or scattered across), if it aims to be maintainable
• if performance isn't critical. Hibernate adds performance overhead, which in some cases can't be ignored.

I have followed the steps and it worked just fine.

1) Open the file present at : \sqldeveloper-3.2.20.09.87\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf and delete the line with setJavaHome xxx .

2) Click on Sqldeveloper.exe now and browse for the java.exe present in \sqldeveloper-3.2.20.09.87\sqldeveloper\jdk\jre\bin

3) This should launch SqlDeveloper now.

Thanks.

In Java, null only applies to object references; since boolean is a primitive type, it cannot be assigned null.

It's hard to get context from your example, but I'm guessing that if hideInNav is not in the object returned by getProperties(), the (default value?) you've indicated will be false. I suspect this is the bug that you're seeing, as false is not equal to null, so hideNavigation is getting the empty string?

You might get some better answers with a bit more context to your code sample.

The lmplot function returns a FacetGrid instance. This object has a method called set, to which you can pass key=value pairs and they will be set on each Axes object in the grid.

Secondly, you can set only one side of an Axes limit in matplotlib by passing None for the value you want to remain as the default.

Putting these together, we have:

g = sns.lmplot('X', 'Y', df, col='Z', sharex=False, sharey=False)
g.set(ylim=(0, None))

Your terminal happens to be configured to UTF-8.

The fact that printing a works is a coincidence; you are writing raw UTF-8 bytes to the terminal. a is a value of length two, containing two bytes, hex values C3 and A1, while ua is a unicode value of length one, containing a codepoint U+00E1.

This difference in length is one major reason to use Unicode values; you cannot easily measure the number of text characters in a byte string; the len() of a byte string tells you how many bytes were used, not how many characters were encoded.

You can see the difference when you encode the unicode value to different output encodings:

>>> a = 'á'
>>> ua = u'á'
>>> ua.encode('utf8')
'\xc3\xa1'
>>> ua.encode('latin1')
'\xe1'
>>> a
'\xc3\xa1'

Note that the first 256 codepoints of the Unicode standard match the Latin 1 standard, so the U+00E1 codepoint is encoded to Latin 1 as a byte with hex value E1.

Furthermore, Python uses escape codes in representations of unicode and byte strings alike, and low code points that are not printable ASCII are represented using \x.. escape values as well. This is why a Unicode string with a code point between 128 and 255 looks just like the Latin 1 encoding. If you have a unicode string with codepoints beyond U+00FF a different escape sequence, \u.... is used instead, with a four-digit hex value.

It looks like you don't yet fully understand what the difference is between Unicode and an encoding. Please do read the following articles before you continue:

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky

I faced same issue. After some Googling with the right search terms, I came across this nice article on DigitalOcean.

haveged is a potential solution without compromising on security.

I am merely quoting the relevant part from the article here.

Based on the HAVEGE principle, and previously based on its associated library, haveged allows generating randomness based on variations in code execution time on a processor. Since it's nearly impossible for one piece of code to take the same exact time to execute, even in the same environment on the same hardware, the timing of running a single or multiple programs should be suitable to seed a random source. The haveged implementation seeds your system's random source (usually /dev/random) using differences in your processor's time stamp counter (TSC) after executing a loop repeatedly

How to install haveged

Follow the steps in this article. https://www.digitalocean.com/community/tutorials/how-to-setup-additional-entropy-for-cloud-servers-using-haveged

I have posted it here

To use DHCP, you'd have to run a DHCP server on the primary and a client on the secondary; the primary could then query the server to find out what address it handed out. Probably overkill.

I can't help you with Windows directly. On Unix, the "arp" command will tell you what IP addresses are known to be attached to the local ethernet segment. Windows will have this same information (since it's a core part of the IP/Ethernet interface) but I don't know how you get at it.

Of course, the networking stack will only know about the other host if it has previously seen traffic from it. You may have to first send a broadcast packet on the interface to elicit some sort of response and thus populate the local ARP table.

This is the best thing I've found so far - shows you the symlinks in the current directory, recursively, but without following them, displayed with full paths and other information:

find ./ -type l -print0 | xargs -0 ls -plah

outputs looks about like this:

lrwxrwxrwx 1 apache develop 99 Dec  5 12:49 ./dir/dir2/symlink1 -> /dir3/symlinkTarget
lrwxrwxrwx 1 apache develop 81 Jan 10 14:02 ./dir1/dir2/dir4/symlink2 -> /dir5/whatever/symlink2Target
etc...

You can also use Date.now() function.

There is no character encoded for use as a pause symbol, though various characters or combinations of characters may look more or less like a pause symbol, depending on font.

In a discussion in the public Unicode mailing list in 2005, a suggestion was made to use two copies of the U+275A HEAVY VERTICAL BAR character: ??. But the adequacy of the result depends on font; for example, the glyph might have been designed so that the bars are too much apart. – The list discussion explains why a pause symbol had not been encoded, and this has not changed.

Thus, the best option is to use an image. If you need to use the symbol in text, it is best to create it in a suitably large size (say 60 by 60 pixels) and scale it down to text size with CSS (e.g., setting height: 0.8em on the img element).

From the documentation (help copy-item -full):

-force <SwitchParameter>
    Allows cmdlet to override restrictions such as renaming existing files as long as security is not compromised.

    Required?                    false
    Position?                    named
    Default value                False
    Accept pipeline input?       false
    Accept wildcard characters?  false

The zip() function in Python 3 returns an iterator. That is the reason why when you print test1 you get - <zip object at 0x1007a06c8>. From documentation -

Make an iterator that aggregates elements from each of the iterables.

But once you do - list(test1) - you have exhausted the iterator. So after that anytime you do list(test1) would only result in empty list.

In case of test2, you have already created the list once, test2 is a list, and hence it will always be that list.

clear:both makes the element drop below any floated elements that precede it in the document.

You can also use clear:left or clear:right to make it drop below only those elements that have been floated left or right.

One solution that may helpful if you want to use the command line emulator cmder. You can install the package installer chocately. First we install chocately in windows command prompt using the following line:

@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"
refreshenv

After chocolatey is installed the choco command can be used to install make. Once installed, you will need add an alias to /cmder/config/user_aliases.cmd. The following line should be added:

make="path_to_chocolatey\chocolatey\bin\make.exe" $*

Make will then operate in the cmder environment.

If you don't want to copy the whole tree (with subdirs etc), use or glob.glob("path/to/dir/*.*") to get a list of all the filenames, loop over the list and use shutil.copy to copy each file.

for filename in glob.glob(os.path.join(source_dir, '*.*')):
    shutil.copy(filename, dest_dir)

There is another option, to use the FinishAffinity method to close all the tasks in the stack related to the app.

See: https://stackoverflow.com/a/27765687/1984636

.show() and .hide() modify the css display rule. I think you want:

$(selector).css('visibility', 'hidden'); // Hide element
$(selector).css('visibility', 'visible'); // Show element

You need to add an additional parameter:

$http.get(url).then(
    function(response) {
        console.log('get',response)
    },
    function(data) {
        // Handle error here
    })

Your alternatives are to override the toString() method of your object to output its contents in a way that you like, or to use reflection to inspect the object (in a way similar to what debuggers do).

The advantage of using reflection is that you won't need to modify your individual objects to be "analysable", but there is added complexity and if you need nested object support you'll have to write that.

This code will list the fields and their values for an Object "o"

Field[] fields = o.getClass().getDeclaredFields();
for (int i=0; i<fields.length; i++)
{

If the intention of the question is to view the contents of the JAR file, then the following java command would help.. (provided, JDK location is added to the environment variables.)

Windows Command prompt> jar tvf yourJarFile.jar

• Example:

I understand your problem boils down to how to call a SOAP (JAX-WS) web service from Java and get its returning object. In that case, you have two possible approaches:

1. Generate the Java classes through wsimport and use them; or
2. Create a SOAP client that:
   1. Serializes the service's parameters to XML;
   2. Calls the web method through HTTP manipulation; and
   3. Parse the returning XML response back into an object.

About the first approach (using wsimport):

I see you already have the services' (entities or other) business classes, and it's a fact that the wsimport generates a whole new set of classes (that are somehow duplicates of the classes you already have).

I'm afraid, though, in this scenario, you can only either:

• Adapt (edit) the wsimport generated code to make it use your business classes (this is difficult and somehow not worth it - bear in mind everytime the WSDL changes, you'll have to regenerate and readapt the code); or
• Give up and use the wsimport generated classes. (In this solution, you business code could "use" the generated classes as a service from another architectural layer.)

About the second approach (create your custom SOAP client):

In order to implement the second approach, you'll have to:

1. Make the call:
   • Use the SAAJ (SOAP with Attachments API for Java) framework (see below, it's shipped with Java SE 1.6 or above) to make the calls; or
   • You can also do it through java.net.HttpUrlconnection (and some java.io handling).
2. Turn the objects into and back from XML:
   • Use an OXM (Object to XML Mapping) framework such as JAXB to serialize/deserialize the XML from/into objects
   • Or, if you must, manually create/parse the XML (this can be the best solution if the received object is only a little bit differente from the sent one).

Creating a SOAP client using classic java.net.HttpUrlConnection is not that hard (but not that simple either), and you can find in this link a very good starting code.

I recommend you use the SAAJ framework:

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {

            The example below requests from the Web Service at:
             https://www.w3schools.com/xml/tempconvert.asmx?op=CelsiusToFahrenheit


            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "https://www.w3schools.com/xml/tempconvert.asmx";
        String soapAction = "https://www.w3schools.com/xml/CelsiusToFahrenheit";

        callSoapWebService(soapEndpointUrl, soapAction);
    }

    private static void createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String myNamespaceURI = "https://www.w3schools.com/xml/";

        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("Celsius", myNamespace);
        soapBodyElem1.addTextNode("100");
    }

    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {

        System.out.println("Request SOAP Message:");
        soapMessage.writeTo(System.out);
        System.out.println("\n");

        return soapMessage;
    }

}

About using JAXB for serializing/deserializing, it is very easy to find information about it. You can start here: http://www.mkyong.com/java/jaxb-hello-world-example/.

The results are not in the Output window but in the Test Results Detail (TestResult Pane at the bottom, right click on on Test Results and go to TestResultDetails).

This works with Debug.WriteLine and Console.WriteLine.

Simplest of all solutions:

df = df.replace(r'^\s+$', np.nan, regex=True)

Like this.

function printMousePos(event) {_x000D_
  document.body.textContent =_x000D_
    "clientX: " + event.clientX +_x000D_
    " - clientY: " + event.clientY;_x000D_
}_x000D_
_x000D_
document.addEventListener("click", printMousePos);

MouseEvent - MDN

MouseEvent.clientX Read only
The X coordinate of the mouse pointer in local (DOM content) coordinates.

MouseEvent.clientY Read only
The Y coordinate of the mouse pointer in local (DOM content) coordinates.

This answer is brought to you by the department of redundancy department.

1. ini_set() / php.ini / .htaccess / .user.ini

   The settings display_errors and error_reporting have been covered sufficiently now. But just to recap when to use which option:

   • ini_set() and error_reporting() apply for runtime errors only.
   • php.ini should primarily be edited for development setups. (Webserver and CLI version often have different php.ini's)
   • .htaccess flags only work for dated setups (Find a new hoster! Well managed servers are cheaper.)
   • .user.ini are partial php.ini's for modern setups (FCGI/FPM)
     
     

   And as crude alternative for runtime errors you can often use:

   set_error_handler("var_dump");   // ignores error_reporting and `@` suppression
   

2. error_get_last()

   Can be used to retrieve the last runtime notice/warning/error, when error_display is disabled.

3. $php_errormsg

   Is a superlocal variable, which also contains the last PHP runtime message.

4. isset() begone!

   I know this will displease a lot of folks, but isset and empty should not be used by newcomers. You can add the notice suppression after you verified your code is working. But never before.

   A lot of the "something doesn't work" questions we get lately are the result of typos like:

   if(isset($_POST['sumbit']))
   #                  ??
   

   You won't get any useful notices if your code is littered with isset/empty/array_keys_exists. It's sometimes more sensible to use @, so notices and warnings go to the logs at least.

5. assert_options(ASSERT_ACTIVE|ASSERT_WARNING);

   To get warnings for assert() sections. (Pretty uncommon, but more proficient code might contain some.)

   PHP7 requires zend.assertions=1 in the php.ini as well.

6. declare(strict_types=1);

   Bending PHP into a strictly typed language is not going to fix a whole lot of logic errors, but it's definitely an option for debugging purposes.

7. PDO / MySQLi

   And @Phil already mentioned PDO/MySQLi error reporting options. Similar options exist for other database APIs of course.

8. json_last_error() + json_last_error_msg

   For JSON parsing.

9. preg_last_error()

   For regexen.

10. CURLOPT_VERBOSE

    To debug curl requests, you need CURLOPT_VERBOSE at the very least.

11. shell/exec()

    Likewise will shell command execution not yield errors on its own. You always need 2>&1 and peek at the $errno.

Try this

btn.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        btn.setBackgroundResource(R.drawable.icon);
    }
});

If you only want one or more columns in the front and don't care about the order of the rest:

require(dplyr)
test %>%
  select(B, everything())

<script>
    ...
    ...jQuery("<script></script>")...
    ...
</script>

The </script> within the string literal terminates the entire script, to avoid that "</scr" + "ipt>" can be used instead.

You could spare yourself the transformations, you could use CSS3 Transitions to flip <div>'s and <ol>'s and any HTML tag you want. Here are some demos with source code explain to see and learn: http://www.webdesignerwall.com/trends/47-amazing-css3-animation-demos/

Long story short, unless len(l1 + l2) ~ 1000000 use:

L = l1 + l2
L.sort()

Description of the figure and source code can be found here.

The figure was generated by the following command:

$ python make-figures.py --nsublists 2 --maxn=0x100000 -s merge_funcs.merge_26 -s merge_funcs.sort_builtin

The Reason is that your previous build is still running in the background. I solve this problem by following these steps:

• Open Task Manager
• Goto Details Tab
• Find Your Application
• End Task it by right clicking on it
• Done!

You could also put a check in the action like: options = !options ? content : options that sets options to the first argument if no second was passed in, and then you just set content to null (or ignore it, however you want to check that)

I think :hover was missing in above answers. So following would do the needful.(if css was required)

#myDiv:hover
{
    cursor: pointer;
}

I figured out Leafpad to be an adequate and simple text-editor to view and save/convert in certain character sets - at least in the linux-world.

I used this to save the Latin-15 to UTF-8 and it worked.

They are the same but the second one is great if you have MVC in your code and don't want to have a lot of echos in your code. For example, in my .phtml files (Zend Framework) I will write something like this:

<?php if($this->value): ?>
Hello
<?php elseif($this->asd): ?>
Your name is: <?= $this->name ?>
<?php else: ?>
You don't have a name.
<?php endif; ?>

As Janoulle pointed out, you don't need to detect which extension it is if you use the WorkbookFactory, it will do it for you. I recently had to implement a solution using NPOI to read Excel files and import email addresses into a sql database. My main problem was that I was probably going to receive about 12 different Excel layouts from different customers so I needed something that could be changed quickly without much code. I ended up using Npoi.Mapper which is an awesome tool! Highly recommended!

Here is my complete solution:

using System.IO;
using System.Linq;
using Npoi.Mapper;
using Npoi.Mapper.Attributes;
using NPOI.SS.UserModel;

namespace JobCustomerImport.Processors
{
    public class ExcelEmailProcessor
    {
        private UserManagementServiceContext DataContext { get; }

        public ExcelEmailProcessor(int customerNumber)
        {
            DataContext = new UserManagementServiceContext();
        }

        public void Execute(string localPath, int sheetIndex)
        {
            IWorkbook workbook;
            using (FileStream file = new FileStream(localPath, FileMode.Open, FileAccess.Read))
            {
                workbook = WorkbookFactory.Create(file);
            }

            var importer = new Mapper(workbook);
            var items = importer.Take<MurphyExcelFormat>(sheetIndex);
            foreach(var item in items)
            {
                var row = item.Value;
                if (string.IsNullOrEmpty(row.EmailAddress))
                    continue;

                UpdateUser(row);
            }

            DataContext.SaveChanges();
        }

        private void UpdateUser(MurphyExcelFormat row)
        {
            //LOGIC HERE TO UPDATE A USER IN DATABASE...
        }

        private class MurphyExcelFormat
        {
            [Column("District")]
            public int District { get; set; }

            [Column("DM")]
            public string FullName { get; set; }

            [Column("Email Address")]
            public string EmailAddress { get; set; }

            [Column(3)]
            public string Username { get; set; }

            public string FirstName
            {
                get
                {
                    return Username.Split('.')[0];
                }
            }

            public string LastName
            {
                get
                {
                    return Username.Split('.')[1];
                }
            }
        }
    }
}

I am so happy with NPOI + Npoi.Mapper (from Donny Tian) as an Excel import solution that I wrote a blog post about it, going in to more detail about this code above. You can read it here if you wish: Easiest way to import excel files. The best thing about this solution is that it runs perfectly in a serverless azure/cloud environment which I couldn't get with other Excel tools/libraries.

1. Using the Property window

   Select form ? go to property window ? select "start position" ? select whatever the place you want.

   

2. Programmatically

   Form form1 = new Form(); form1.StartPosition = FormStartPosition.CenterScreen; form1.ShowDialog();

   Note: Do not directly call Form.CenterToScreen() from your code. Read here.

You can also use this code to get LayoutInflater:

LayoutInflater li = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)

If you want to control the formatting of the unique identifier you can create your own <FieldType> in SharePoint. MSDN also has a visual How-To. This basically means that you're creating a custom column.

WSS defines the Counter field type (which is what the ID column above is using). I've never had the need to re-use this or extend it, but it should be possible.

A solution might exist without creating a custom <FieldType>. For example: if you wanted unique IDs like CUST1, CUST2, ... it might be possible to create a Calculated column and use the value of the ID column in you formula (="CUST" & [ID]). I haven't tried this, but this should work :)

Try this macro to test the overflow bit of 32-bit machines (adapted the solution of Angel Sinigersky)

#define overflowflag(isOverflow){   \
size_t eflags;                      \
asm ("pushfl ;"                     \
     "pop %%eax"                    \
    : "=a" (eflags));               \
isOverflow = (eflags >> 11) & 1;}

I defined it as a macro because otherwise the overflow bit would have been overwritten.

Subsequent is a little application with the code segement above:

#include <cstddef>
#include <stdio.h>
#include <iostream>
#include <conio.h>
#if defined( _MSC_VER )
#include <intrin.h>
#include <oskit/x86>
#endif

using namespace std;

#define detectOverflow(isOverflow){     \
size_t eflags;                      \
asm ("pushfl ;"                     \
    "pop %%eax"                     \
    : "=a" (eflags));               \
isOverflow = (eflags >> 11) & 1;}

int main(int argc, char **argv) {

    bool endTest = false;
    bool isOverflow;

    do {
        cout << "Enter two intergers" << endl;
        int x = 0;
        int y = 0;
        cin.clear();
        cin >> x >> y;
        int z = x * y;
        detectOverflow(isOverflow)
        printf("\nThe result is: %d", z);
        if (!isOverflow) {
            std::cout << ": no overflow occured\n" << std::endl;
        } else {
            std::cout << ": overflow occured\n" << std::endl;
        }

        z = x * x * y;
        detectOverflow(isOverflow)
        printf("\nThe result is: %d", z);
        if (!isOverflow) {
            std::cout << ": no overflow ocurred\n" << std::endl;
        } else {
            std::cout << ": overflow occured\n" << std::endl;
        }

        cout << "Do you want to stop? (Enter \"y\" or \"Y)" << endl;

        char c = 0;

        do {
            c = getchar();
        } while ((c == '\n') && (c != EOF));

        if (c == 'y' || c == 'Y') {
            endTest = true;
        }

        do {
            c = getchar();
        } while ((c != '\n') && (c != EOF));

    } while (!endTest);
}

There is an alternative command where you can get the raw value of a cell where formula is put on. It's returns type is String. Use:

cell.getRawValue();

The problem I see here is that "sum" is an aggregate function.

first, you need to fix the query itself.

Select sum(c_counts + f_counts) total, [column to group sums by]
from table
group by [column to group sums by]

then, you can sort it:

Select *
from (query above) a
order by total

EDIT: But see post by Virat. Perhaps what you want is not the sum of your total fields over a group, but just the sum of those fields for each record. In that case, Virat has the right solution.

I found this page while trying to center align a pair of videos. So, if I enclose both videos in a center div (which I've called central), the margin trick works, but the width is important (2 videos at 400 + padding etc)

<div class=central>
    <video id="vid1" width="400" controls>
        <source src="Carnival01.mp4" type="video/mp4">
    </video> 

    <video id="vid2" width="400" controls>
        <source src="Carnival02.mp4" type="video/mp4">
    </video>
</div>

<style>
div.central { 
  margin: 0 auto;
  width: 880px; <!--this value must be larger than both videos + padding etc-->
}
</style>

Worked for me!

Setting html { height: 100%} can wreak havoc with IE. Here's an example (png). But you know what works great? Just set your background on the <html> tag.

html {
  -moz-linear-gradient(top, #fff, #000);
  /* etc. */
}

Background extends to the bottom and no weird scrolling behavior occurs. You can skip all of the other fixes. And this is broadly supported. I haven't found a browser that doesn't let you apply a background to the html tag. It's perfectly valid CSS and has been for a while. :)

Angular JS does this way.

msie = parseInt((/msie (\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
if (isNaN(msie)) {
  msie = parseInt((/trident\/.*; rv:(\d+)/.exec(navigator.userAgent.toLowerCase()) || [])[1]);
}

msie will be positive number if its IE and NaN for other browser like chrome,firefox.

why ?

As of Internet Explorer 11, the user-agent string has changed significantly.

You are more vulnerable to attacks if using eval: JSON is a subset of Javascript and json.parse just parses JSON whereas eval would leave the door open to all JS expressions.

In Java, 2D arrays are really arrays of arrays with possibly different lengths (there are no guarantees that in 2D arrays that the 2nd dimension arrays all be the same length)

You can get the length of any 2nd dimension array as z[n].length where 0 <= n < z.length.

If you're treating your 2D array as a matrix, you can simply get z.length and z[0].length, but note that you might be making an assumption that for each array in the 2nd dimension that the length is the same (for some programs this might be a reasonable assumption).

You can use ::after to create a 0px-height block after the <h4>, which effectively moves anything after the <h4> to the next line:

h4 {_x000D_
  display: inline;_x000D_
}_x000D_
h4::after {_x000D_
  content: "";_x000D_
  display: block;_x000D_
}

<ul>_x000D_
  <li>_x000D_
    Text, text, text, text, text. <h4>Sub header</h4>_x000D_
    Text, text, text, text, text._x000D_
  </li>_x000D_
</ul>

@NLwino, yery good query with a few errors for keyword usage. I had to modify it a little to wrap the keywords with [ ] and also look char and ntext columns.

    DECLARE @searchstring  NVARCHAR(255)
    SET @searchstring = '%WDB1014%'

    DECLARE @sql NVARCHAR(max)

    SELECT @sql = STUFF((
      SELECT ' UNION ALL SELECT ''' + TABLE_NAME + ''' AS tbl, ''' + COLUMN_NAME + ''' AS col, [' + COLUMN_NAME + '] AS val' + 
        ' FROM ' + TABLE_SCHEMA + '.[' + TABLE_NAME + 
        '] WHERE [' + COLUMN_NAME + '] LIKE ''' + @searchstring + ''''
        FROM INFORMATION_SCHEMA.COLUMNS 
        WHERE DATA_TYPE in ('nvarchar', 'varchar', 'char', 'ntext')
                  FOR XML PATH('')
             ) ,1, 11, '')

    Exec (@sql)

I ran it on 2.5 GB database and it came back in 51 seconds

For SSIS you could go with:

RIGHT("0" + (DT_STR, 2, 1252) DATEPART("dd" , GETDATE()), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("mm" , GETDATE()), 2) + "-" +  (DT_STR, 4, 1252) DATEPART("yy" , GETDATE())

Expression builder screen:

Subtracting the Minimum of the ends of the ranges from the Maximum of the beginning seems to do the trick. If the result is less than or equal to zero, we have an overlap. This visualizes it well:

The below solution is the simplest one:

Console.WriteLine("[{0}]", string.Join(", ", array));

Output: [1, 2, 3, 4, 5]

Another short solution:

Array.ForEach(array,  val => Console.Write("{0} ", val));

Output: 1 2 3 4 5. Or if you need to add add ,, use the below:

int i = 0;
Array.ForEach(array,  val => Console.Write(i == array.Length -1) ? "{0}" : "{0}, ", val));

Output: 1, 2, 3, 4, 5

Weird issue, but this helped me to solve my issue. Sometimes even the easiest things are hard to figure out...

Instead of using /js/main.css in my script-tag I used js/main.css

YES, it did actually make a difference. I'm sitting on WAMP / Windows and I didn't have a vhost but just used localhost/<project>

If I reference to /js/main.css then I reference to localhost/css/main.css and not to localhost/<project>/css/main.css

When you think of it, it's quite obvious but if someone stumbles upon this I thought I would share this answer.

purls $.params() used without a parameter will give you a key-value object of the parameters.

jQuerys $.param() will build a querystring from the supplied object/array.

var params = parsedUrl.param();
delete params["page"];

var newUrl = "?page=" + $(this).val() + "&" + $.param(params);

Update
I've no idea why I used delete here...

var params = parsedUrl.param();
params["page"] = $(this).val();

var newUrl = "?" + $.param(params);

GROUP_CONCAT has DISTINCT attribute:

SELECT GROUP_CONCAT(DISTINCT categories ORDER BY categories ASC SEPARATOR ' ') FROM table

You can use the cherry-pick to get the particular bug fix commit(s)

$ git checkout branch
$ git cherry-pick bugfix

As we know dispose and finalize both are used to free unmanaged resources.. but the difference is finalize uses two cycle to free the resources , where as dispose uses one cycle..

If you have created your HTML element dynamically, you'll want to disable the attribute via JS. There is a little trap however:

When setting elem.contentEditable you can use either the boolean false or the string "false". But when you set elem.spellcheck, you can only use the boolean - for some reason. Your options are thus:

elem.spellcheck = false;

Or the option Mac provided in his answer:

elem.setAttribute("spellcheck", "false"); // Both string and boolean work here. 

You can add a watchpoint for each variable you're interested in.

A watchpoint is a special breakpoint that stops the execution of an application whenever the value of a given expression changes, without specifying where it might occur. Unlike breakpoints (which are line-specific), watchpoints are associated with files. They take effect whenever a specified condition is true, regardless of when or where it occurred. You can set a watchpoint on a global variable by highlighting the variable in the editor, or by selecting it in the Outline view.

Use set.update() or |=

>>> a = set('abc')
>>> l = ['d', 'e']
>>> a.update(l)
>>> a
{'e', 'b', 'c', 'd', 'a'}

>>> l = ['f', 'g']
>>> a |= set(l)
>>> a
{'e', 'b', 'f', 'c', 'd', 'g', 'a'}

edit: If you want to add the list itself and not its members, then you must use a tuple, unfortunately. Set members must be hashable.

Just a piece of advice. Instead of writing

for (int i=0; i=((Main.size())-1); i++) {
   cout << Main[i] << '\n';
}

as suggested above, write a:

for (vector<double>::iterator it=Main.begin(); it!=Main.end(); it++) {
   cout << *it << '\n';
}

to use iterators. If you have C++11 support, you can declare i as auto i=Main.begin() (just a handy shortcut though)

This avoids the nasty one-position-out-of-bound error caused by leaving out a -1 unintentionally.

use iframe onload event

$('#theiframe').on("load", function() {

});

You have more than one form tags with runat="server" on your template, most probably you have one in your master page, remove one on your aspx page, it is not needed if already have form in master page file which is surrounding your content place holders.

Try to remove that tag:

<form id="formID" runat="server">

and of course closing tag:

</form>

The Express API doc spells this out pretty clearly.

Additionally this answer gives the steps to create a self-signed certificate.

I have added some comments and a snippet from the Node.js HTTPS documentation:

var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');

// This line is from the Node.js HTTPS documentation.
var options = {
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.cert')
};

// Create a service (the app object is just a callback).
var app = express();

// Create an HTTP service.
http.createServer(app).listen(80);
// Create an HTTPS service identical to the HTTP service.
https.createServer(options, app).listen(443);

Install the SharpVectors library

Install-Package SharpVectors

Add the following in XAML

<UserControl xmlns:svgc="http://sharpvectors.codeplex.com/svgc">
    <svgc:SvgViewbox Source="/Icons/icon.svg"/>
</UserControl>

Normally this error occurs when you invoke java by supplying the wrong arguments/options. In this case it should be the version option.

java -version

So to double check you can always do java -help, and see if the option exists. In this case, there is no option such as v.

It is usually handled automatically.

If autodiscovery doesn't work. Edit the elastic search config file, by enabling unicast discovery

Node 1:

    cluster.name: mycluster
    node.name: "node1"
    node.master: true
    node.data: true
    discovery.zen.ping.multicast.enabled: false
    discovery.zen.ping.unicast.hosts: ["node1.example.com"]

Node 2:

    cluster.name: mycluster
    node.name: "node2"
    node.master: false
    node.data: true
    discovery.zen.ping.multicast.enabled: false
    discovery.zen.ping.unicast.hosts: ["node1.example.com"]

and so on for node 3,4,5. Make node 1 master, and the rest only as data nodes.

Edit: Please note that by ES rule, if you have N nodes, then by convention, N/2+1 nodes should be masters for fail-over mechanisms They may or may not be data nodes, though.

Also, in case auto-discovery doesn't work, most probable reason is because the network doesn't allow it (and therefore disabled). If too many auto-discovery pings take place across multiple servers, the resources to manage those pings will prevent other services from running correctly.

For ex, think of a 10,000 node cluster and all 10,000 nodes doing the auto-pings.

This is based on @Safak's answer. The best way to understand the axes in pandas/numpy is to create a 3d array and check the result of the sum function along the 3 different axes.

 a = np.ones((3,5,7))

a will be:

    array([[[1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.]],

   [[1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.]],

   [[1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.],
    [1., 1., 1., 1., 1., 1., 1.]]])

Now check out the sum of elements of the array along each of the axes:

 x0 = np.sum(a,axis=0)
 x1 = np.sum(a,axis=1)
 x2 = np.sum(a,axis=2)

will give you the following results:

   x0 :
   array([[3., 3., 3., 3., 3., 3., 3.],
        [3., 3., 3., 3., 3., 3., 3.],
        [3., 3., 3., 3., 3., 3., 3.],
        [3., 3., 3., 3., 3., 3., 3.],
        [3., 3., 3., 3., 3., 3., 3.]])

   x1 : 
   array([[5., 5., 5., 5., 5., 5., 5.],
   [5., 5., 5., 5., 5., 5., 5.],
   [5., 5., 5., 5., 5., 5., 5.]])

  x2 :
   array([[7., 7., 7., 7., 7.],
        [7., 7., 7., 7., 7.],
        [7., 7., 7., 7., 7.]])

You can replace

document.getElementById(this.state.baction).addPrecent(10);

with

this.refs[this.state.baction].addPrecent(10);


  <Progressbar completed={25} ref="Progress1" id="Progress1"/>

You can simply use stream method to not download the full file. As in latest Python3 you won't get urllib2. It's best to use proven request method. This simple function will solve your problem.

def uri_exists(uri):
    r = requests.get(url, stream=True)
    if r.status_code == 200:
        return True
    else:
        return False

you have to replace empty strings ('') with np.nan before converting to float. ie:

df['a']=df.a.replace('',np.nan).astype(float)

1. open service control manager database using openscmanager
2. get dependent service using EnumDependService()
3. Stop all dependent services using ChangeConfig() sending STOP signal to this function if they are started
4. stop actual service
5. Get all Services dependencies of a service
6. Start all services dependencies using StartService() if they are stopped
7. Start actual service

Thus your service is restarted taking care all dependencies.

HTTP does not place a predefined limit on the length of each header field or on the length of the header section as a whole, as described in Section 2.5. Various ad hoc limitations on individual header field length are found in practice, often depending on the specific field semantics.

HTTP Header values are restricted by server implementations. Http specification doesn't restrict header size.

A server that receives a request header field, or set of fields, larger than it wishes to process MUST respond with an appropriate 4xx (Client Error) status code. Ignoring such header fields would increase the server's vulnerability to request smuggling attacks (Section 9.5).

Most servers will return 413 Entity Too Large or appropriate 4xx error when this happens.

A client MAY discard or truncate received header fields that are larger than the client wishes to process if the field semantics are such that the dropped value(s) can be safely ignored without changing the message framing or response semantics.

Uncapped HTTP header size keeps the server exposed to attacks and can bring down its capacity to serve organic traffic.

editText.setInputType(InputType.TYPE_NULL);

... takes no arguments and has a void return type?

I believe Action is a solution to this.

For MySQL, use

SELECT column_name 
FROM information_schema.columns 
WHERE 
table_schema = 'Schema' AND table_name = 'Table_Name'

l = [15, 18, 2, 36, 12, 78, 5, 6, 9]
sum(l) / len(l)

You can use localStorage. This is the Html5 equivalent of cookies. It appears to work on Chrome and Firefox BUT on Firefox, I needed to upload it to a server. That is, testing directly on my home computer didn't work.

I'm working up HTML5 examples. Go to http://faculty.purchase.edu/jeanine.meyer/html5/html5explain.html and scroll to the maze one. The information to re-build the maze is stored using localStorage.

I came to this article looking for HTML5 JavaScript for loading and working with xml files. Is it the same as older html and JavaScript????

Add CultureInfo.InvariantCulture as an argument:

using System.Globalization;

...

var dateTime = new DateTime(2016,8,16);
dateTime.ToString("dd/MM/yyyy", CultureInfo.InvariantCulture);

Will return:

"16/08/2016"

Loop through the array like any other Associative Array:

while($data = $datas->fetch( PDO::FETCH_ASSOC )){ 
     print $data['title'].'<br>'; 
}

or

$resultset = $datas->fetchALL(PDO::FETCH_ASSOC);

echo '<pre>'.$resultset.'</pre>';

None of the other answers worked for me so I wrote my own solution:

As of Oracle 11g.

Replace USER with the desired username

Granted Roles:

SELECT * 
  FROM DBA_ROLE_PRIVS 
 WHERE GRANTEE = 'USER';

Privileges Granted Directly To User:

SELECT * 
  FROM DBA_TAB_PRIVS 
 WHERE GRANTEE = 'USER';

Privileges Granted to Role Granted to User:

SELECT * 
  FROM DBA_TAB_PRIVS  
 WHERE GRANTEE IN (SELECT granted_role 
                     FROM DBA_ROLE_PRIVS 
                    WHERE GRANTEE = 'USER');

Granted System Privileges:

SELECT * 
  FROM DBA_SYS_PRIVS 
 WHERE GRANTEE = 'USER';

If you want to lookup for the user you are currently connected as, you can replace DBA in the table name with USER and remove the WHERE clause.

You can use the "ORDER BY DESC" option, then put it back in the original order:

(SELECT * FROM tablename ORDER BY id DESC LIMIT 10) ORDER BY id;

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

void foo(int a)
void foo(int a, float b)

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

class Parent {
    void foo(double d) {
        // do something
    }
}

class Child extends Parent {

    @Override
    void foo(double d){
        // this method is overridden.  
    }
}

add path(:/usr/local/bin/) in profile.

Some handy script:

The solution below worked for me. It successfully sends an email to multiple recipients, including "CC" and "BCC."

toaddr = ['mailid_1','mailid_2']
cc = ['mailid_3','mailid_4']
bcc = ['mailid_5','mailid_6']
subject = 'Email from Python Code'
fromaddr = 'sender_mailid'
message = "\n  !! Hello... !!"

msg['From'] = fromaddr
msg['To'] = ', '.join(toaddr)
msg['Cc'] = ', '.join(cc)
msg['Bcc'] = ', '.join(bcc)
msg['Subject'] = subject

s.sendmail(fromaddr, (toaddr+cc+bcc) , message)

Stan0 intial idea is not a good idea. There can be multiple files with the same name. Very error prone implementation. Stan0's second idea is the correct way.

When you first upload the file to google drive store its id (in SharedPreferences is probably easiest) for later use

ie.

file= mDrive.files().insert(body).execute();      //initial insert of file to google drive

whereverYouWantToStoreIt= file.getId(); //now you have the guaranteed unique id 
                                        //of the file just inserted. Store it and use it 
                                        //whenever you need to fetch this file

The very basic thing is static variables or static methods are at class level. Class level variables or methods gets loaded prior to instance level methods or variables.And obviously the thing which is not loaded can not be used. So java compiler not letting the things to be handled at run time resolves at compile time. That's why it is giving you error non-static things can not be referred from static context. You just need to read about Class Level Scope, Instance Level Scope and Local Scope.

UTF-8 is prepared for world domination, Latin1 isn't.

If you're trying to store non-Latin characters like Chinese, Japanese, Hebrew, Russian, etc using Latin1 encoding, then they will end up as mojibake. You may find the introductory text of this article useful (and even more if you know a bit Java).

Note that full 4-byte UTF-8 support was only introduced in MySQL 5.5. Before that version, it only goes up to 3 bytes per character, not 4 bytes per character. So, it supported only the BMP plane and not e.g. the Emoji plane. If you want full 4-byte UTF-8 support, upgrade MySQL to at least 5.5 or go for another RDBMS like PostgreSQL. In MySQL 5.5+ it's called utf8mb4.

try like this

$('title').text();

There are a few ways this can be completed.

Elements know which form they belong to, so you don't need to wrap this in jquery, you can just call this.form which returns the form element. Then you can call submit() on a form element to submit it.

  $('select').on('change', function(e){
    this.form.submit()
  });

Hovercraft Full Of Eels' answer is very good, but i had to change it a bit in order to get it working on my program:

int y1 = (int) ((this.height - 2 * BORDER_GAP) - (values.get(i) * yScale - BORDER_GAP));

instead of

int y1 = (int) (scores.get(i) * yScale + BORDER_GAP);

because if i used his way the graphic would be upside down

(you'd see it if you used hardcoded values (e.g 1,3,5,7,9) instead of random values)

With the upcoming Xcode 7 it's now possible to install apps on your devices without an apple developer license, so now it is possible to skip the app store and you don't have to jailbreak your device.

Now everyone can get their app on their Apple device.

Xcode 7 and Swift now make it easier for everyone to build apps and run them directly on their Apple devices. Simply sign in with your Apple ID, and turn your idea into an app that you can touch on your iPad, iPhone, or Apple Watch. Download Xcode 7 beta and try it yourself today. Program membership is not required.

Quoted from: https://developer.apple.com/xcode/

Update:

XCode 7 is now released:

Free On-Device Development Now everyone can run and test their own app on a device—for free. You can run and debug your own creations on a Mac, iPhone, iPad, iPod touch, or Apple Watch without any fees, and no programs to join. All you need to do is enter your free Apple ID into Xcode. You can even use the same Apple ID you already use for the App Store or iTunes. Once you’ve perfected your app the Apple Developer Program can help you get it on the App Store.

See Launching Your App on Devices for detailed information about installing and running on devices.

Gumbo's solution does not work. This one does though:

  var passwd = '';
  var chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
  for (i=1;i<8;i++) {
    var c = Math.floor(Math.random()*chars.length + 1);
    passwd += chars.charAt(c)
  }

  return passwd;

Here I have one simple example of the closure concept which we can use for in our E-commerce site or many others as well.

I am adding my JSFiddle link with the example. It contains a small product list of three items and one cart counter.

    value: function(){
      return counter;
    }
  }
}

var cartCount = CartCouter();

function updateCart() {
  document.getElementById('cartcount').innerHTML = cartCount.value();
}

var productlist = document.getElementsByClassName('item');
for(var i = 0; i< productlist.length; i++){
  productlist[i].addEventListener('click', function(){
    if(this.className.indexOf('selected') < 0){
      this.className += " selected";
      cartCount.increment();
      updateCart();
    }
    else{
      this.className = this.className.replace("selected", "");
      cartCount.decrement();
      updateCart();
    }
  })
}

As of PowerShell 5.1 there cmdlet New-LocalUser which could create local user account.

Example of usage:

Create a user account

New-LocalUser -Name "User02" -Description "Description of this account." -NoPassword

or Create a user account that has a password

$Password = Read-Host -AsSecureString
New-LocalUser "User03" -Password $Password -FullName "Third User" -Description "Description of this account."

or Create a user account that is connected to a Microsoft account

New-LocalUser -Name "MicrosoftAccount\usr [email protected]" -Description "Description of this account." 

The next step would be FisherFaces. Try it and check whether they work for you. Here is a nice comparison.

Using solve with a single parameter is a request to invert a matrix. The error message is telling you that your matrix is singular and cannot be inverted.

In Java, 0 is the same as 0.0, and doubles default to 0 (though many advise always setting them explicitly for improved readability). I have checked and foo.x == 0 and foo.x == 0.0 are both true if foo.x is zero

As per damienfrancois's suggestion, I installed libcurl4-gnutls-dev and the problem was solved.

EDIT (@dardisco)

In your shell:

apt-get -y build-dep libcurl4-gnutls-dev
apt-get -y install libcurl4-gnutls-dev

For Groovy script in the Jenkinsfile using the $BUILD_NUMBER it works.

I was following along the Vue documentation at https://vuejs.org/v2/guide/index.html when I ran into this issue.

Later they clarify the syntax:

So far, we’ve only registered components globally, using Vue.component:

   Vue.component('my-component-name', {
       // ... options ...
   })

Globally registered components can be used in the template of any root Vue instance (new Vue) created afterwards – and even inside all >subcomponents of that Vue instance’s component tree.

(https://vuejs.org/v2/guide/components.html#Organizing-Components)

So as Umesh Kadam says above, just make sure the global component definition comes before the var app = new Vue({}) instantiation.

Try this:

window.onmousewheel = document.onmousewheel = null
window.ontouchmove = null 
window.onwheel = null 

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

So I found this on php.net page for preg_replace function

// replace accented chars

$string = "Zacarías Ferreíra"; // my definition for string variable
$accents = '/&([A-Za-z]{1,2})(grave|acute|circ|cedil|uml|lig);/';

$string_encoded = htmlentities($string,ENT_NOQUOTES,'UTF-8');

$string = preg_replace($accents,'$1',$string_encoded);

If you have encoding issues you may get someting like this "Zacarías Ferreíra", just decode the string and use said code above

$string = utf8_decode("Zacarías Ferreíra");

I have checked on Windows: Ctrl + F11 and Ctrl + F12 both are working to change the orientation of the Android simulator.

For other shortcut keys:

In the Eclipse toolbar go to "Help-->key Assist.. "

You can also use Ctrl + Shift + L here, so many shortcut keys of Eclipse are given.

This works:

var img = document.createElement('img');
img.src = 'img/eqp/' + this.apparel + '/' + this.facing + '_idle.png';
document.getElementById('gamediv').appendChild(img)

Or using jQuery:

$('<img/>')
.attr('src','img/eqp/' + this.apparel + '/' + this.facing + '_idle.png')
.appendTo('#gamediv');

Like that we can do....

int main(int argc, char *argv[]) {

    int a, b, c;
    *// Converting string type to integer type
    // using function "atoi( argument)"* 

    a = atoi(argv[1]);     
    b = atoi(argv[2]);

The -match operator tests a regex, combine it with the magic variable $matches to get your result

PS C:\> $x = "----start----Hello World----end----"
PS C:\> $x -match "----start----(?<content>.*)----end----"
True
PS C:\> $matches['content']
Hello World

You need to create a new Jpanel object in the Board constructor. for example

public Board(){
    JPanel pane = new JPanel();
    pane.setBackground(Color.ORANGE);// sets the background to orange
} 

You need to add the tomcat dependency in your pom

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
</dependency>

I had this error 2 times. Each time it was solved by changing the ajax type. Either GET to POST or POST to GET.

$.ajax({

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

File                             Thread Safe         VC Bulid
php_sqlsrv_53_nts_vc6.dll           No                  VC6
php_sqlsrv_53_nts_vc9.dll           No                  VC9
php_sqlsrv_53_ts_vc6.dll            Yes                 VC6
php_sqlsrv_53_ts_vc9.dll            Yes                 VC9

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

extension=php_sqlsrv_53_*_vc*.dll

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.

In my case the solution was to wait 5 minutes. Obviously my previous operation was still running but I just didn't know it. I was using tortoise git on windows.

Simple 'docker' command knows nothing about 'worker' container. Use command like this

docker-compose -f docker-compose.yml restart worker

Came here looking for a solution to a similar issue, which I just introduced by changing Schannel settings of our IIS server using "IIS Crypto" by Nartac... By disabling the SHA-1 hash, the local SQL Server was not able to be reached anymore, even though I didn't use an encrypted connection (not useful for an ASP.Net site accessing a local SQL Express instance using shared memory).

Thanks Count Zero for pointing me in the right direction :-)

So, lesson learned: do not disable SHA-1 on your IIS server if you have a local SQL Server instance.

I think the cleanest way is definitely to go the AOP route. Make a few aspects, add the necessary attributes, and you never have to check thread affinity again.

If there is not ISNULL() method, you can use this expression instead:

CASE WHEN fieldname IS NULL THEN 0 ELSE fieldname END

This works the same as ISNULL(fieldname, 0).

Not sure if any of these help, but this might get you started: http://studiostyles.info

I know that the site owner has been gradually adding functionality to allow support for new color assignments, so perhaps there's something there.

Just in case if it could help someone like me.

Based on the Official website and the Accepted answer, I made a code using C# that uses System.Data.SQLite NuGet package.

This code also preserves the Primary key and Foreign key.

CODE in C#:

parentElement is new to Firefox 9 and to DOM4, but it has been present in all other major browsers for ages.

In most cases, it is the same as parentNode. The only difference comes when a node's parentNode is not an element. If so, parentElement is null.

As an example:

document.body.parentNode; // the <html> element
document.body.parentElement; // the <html> element

document.documentElement.parentNode; // the document node
document.documentElement.parentElement; // null

(document.documentElement.parentNode === document);  // true
(document.documentElement.parentElement === document);  // false

Since the <html> element (document.documentElement) doesn't have a parent that is an element, parentElement is null. (There are other, more unlikely, cases where parentElement could be null, but you'll probably never come across them.)

I am using Angular 5 with Boostrap 4. It works for me in this way.

You shouldn't be setting x = []. That is setting an empty list to your inputted parameter. Furthermore, use python's for i in x syntax as follows:

for i in x:
    if i.isalpha():
        letters+=1
    elif i.isnumeric():
        digit+=1
    elif i.isspace():
        space+=1
    else:
        other+=1

It's optional.

The port may be specified so cookies can be port specific. It's not necessary, the web server / application must care of this.

I built this in LINQPad:

var listOfNames = new List<string>(){"John","Steve","Anna","Chris"};

var listCount = listOfNames.Count;

var NamesWithCommas = string.Empty;

foreach (var element in listOfNames)
{
    NamesWithCommas += element;
    if(listOfNames.IndexOf(element) != listCount -1)
    {
        NamesWithCommas += ", ";
    }
}

NamesWithCommas.Dump();  //LINQPad method to write to console.

You could also just use string.join:

var joinResult = string.Join(",", listOfNames);

Say if you have an application which has similar functionality as that of mine. Where your app is mostly offline and you want to render the Images one after the other. Then below is the approach that worked for me in React Native version 0.60.

1. First create a folder named Resources/Images and place all your images there.
2. Now create a file named Index.js (at Resources/Images) which is responsible for Indexing all the images in the Reources/Images folder.

const Images = { 'image1': require('./1.png'), 'image2': require('./2.png'), 'image3': require('./3.png') }

3. Now create a Component named ImageView at your choice of folder. One can create functional, class or constant component. I have used Const component. This file is responsible for returning the Image depending on the Index.

import React from 'react';
import { Image, Dimensions } from 'react-native';
import Images from './Index';
const ImageView = ({ index }) => {
    return (
        <Image
            source={Images['image' + index]}
        />
    )
}
export default ImageView;

4. Now from the component wherever you want to render the Static Images dynamically, just use the ImageView component and pass the index.

   < ImageView index={this.qno + 1} />

It may well be that you're running WordPress core tests, and have recently upgraded your PhpUnit to version 6. If that's the case, then the recent change to namespacing in PhpUnit will have broken your code.

Fortunately, there's a patch to the core tests at https://core.trac.wordpress.org/changeset/40547 which will work around the problem. It also includes changes to travis.yml, which you may not have in your setup; if that's the case then you'll need to edit the .diff file to ignore the Travis patch.

1. Download the "Unified Diff" patch from the bottom of https://core.trac.wordpress.org/changeset/40547

2. Edit the patch file to remove the Travis part of the patch if you don't need that. Delete from the top of the file to just above this line:

   Index: /branches/4.7/tests/phpunit/includes/bootstrap.php
   

3. Save the diff in the directory above your /includes/ directory - in my case this was the Wordpress directory itself

4. Use the Unix patch tool to patch the files. You'll also need to strip the first few slashes to move from an absolute to a relative directory structure. As you can see from point 3 above, there are five slashes before the include directory, which a -p5 flag will get rid of for you.

   $ cd [WORDPRESS DIRECTORY]
   $ patch -p5 < changeset_40547.diff 
   

After I did this my tests ran correctly again.

A typical custom exception I'd define is something like this:

public class CustomException extends Exception {

    public CustomException(String message) {
        super(message);
    }

    public CustomException(String message, Throwable throwable) {
        super(message, throwable);
    }

}

I even create a template using Eclipse so I don't have to write all the stuff over and over again.

in my case, I was not writing reg_url with :8080 . String reg_url = "http://192.168.29.163:8080/register.php";

No, it sets all members/elements that haven't been explicitly set to their default-initialisation value, which is zero for numeric types.

Database table

Having the following blog database table storing the blogs hosted by our platform:

And, we have two blogs currently hosted:

Getting our report without using the SQL LATERAL JOIN

We need to build a report that extracts the following data from the blog table:

• the blog id
• the blog age, in years
• the date for the next blog anniversary
• the number of days remaining until the next anniversary.

If you're using PostgreSQL, then you have to execute the following SQL query:

SELECT
  b.id as blog_id,
  extract(
    YEAR FROM age(now(), b.created_on)
  ) AS age_in_years,
  date(
    created_on + (
      extract(YEAR FROM age(now(), b.created_on)) + 1
    ) * interval '1 year'
  ) AS next_anniversary,
  date(
    created_on + (
      extract(YEAR FROM age(now(), b.created_on)) + 1
    ) * interval '1 year'
  ) - date(now()) AS days_to_next_anniversary
FROM blog b
ORDER BY blog_id

As you can see, the age_in_years has to be defined three times because you need it when calculating the next_anniversary and days_to_next_anniversary values.

And, that's exactly where LATERAL JOIN can help us.

Getting the report using the SQL LATERAL JOIN

The following relational database systems support the LATERAL JOIN syntax:

• Oracle since 12c
• PostgreSQL since 9.3
• MySQL since 8.0.14

SQL Server can emulate the LATERAL JOIN using CROSS APPLY and OUTER APPLY.

LATERAL JOIN allows us to reuse the age_in_years value and just pass it further when calculating the next_anniversary and days_to_next_anniversary values.

The previous query can be rewritten to use the LATERAL JOIN, as follows:

SELECT
  b.id as blog_id,
  age_in_years,
  date(
    created_on + (age_in_years + 1) * interval '1 year'
  ) AS next_anniversary,
  date(
    created_on + (age_in_years + 1) * interval '1 year'
  ) - date(now()) AS days_to_next_anniversary
FROM blog b
CROSS JOIN LATERAL (
  SELECT
    cast(
      extract(YEAR FROM age(now(), b.created_on)) AS int
    ) AS age_in_years
) AS t
ORDER BY blog_id

And, the age_in_years value can be calculated one and reused for the next_anniversary and days_to_next_anniversary computations:

Much better, right?

The age_in_years is calculated for every record of the blog table. So, it works like a correlated subquery, but the subquery records are joined with the primary table and, for this reason, we can reference the columns produced by the subquery.

zvolkov's answer is the perfect one to find out if there is such a customer. If you need to use the customer afterwards, you can do:

Customer customer = list.FirstOrDefault(cus => cus.FirstName == "John");
if (customer != null)
{
    // Use customer
}

I know this isn't what you were asking, but I thought I'd pre-empt a follow-on question :) (Of course, this only finds the first such customer... to find all of them, just use a normal where clause.)

The easiest and cleanest way I've found is to use a data attribute to store your custom error. Test the node for validity and handle the error by using some custom html.

le javascript

if(node.validity.patternMismatch)
        {
            message = node.dataset.patternError;
        }

and some super HTML5

<input type="text" id="city" name="city" data-pattern-error="Please use only letters for your city." pattern="[A-z ']*" required>

On Windows:

1. Assign value to PGPASSWORD: C:\>set PGPASSWORD=pass

2. Run command: C:\>psql -d database -U user

Ready

Or in one line,

set PGPASSWORD=pass&& psql -d database -U user

Note the lack of space before the && !

You need to make the x-factor into an ordered factor with the ordering you want, e.g

x <- data.frame("variable"=letters[1:5], "value"=rnorm(5)) ## example data
x <- x[with(x,order(-value)), ] ## Sorting
x$variable <- ordered(x$variable, levels=levels(x$variable)[unclass(x$variable)])

ggplot(x, aes(x=variable,y=value)) + geom_bar() +
   scale_y_continuous("",formatter="percent") + coord_flip()

I don't know any better way to do the ordering operation. What I have there will only work if there are no duplicate levels for x$variable.

A complete example for scripted pipepline:

       stage('Build'){
            withEnv(["GOPATH=/ws","PATH=/ws/bin:${env.PATH}"]) {
                sh 'bash build.sh'
            }
        }

The function below will take as input # of minutes and output time in the following format: Hours:minutes. I used Math.trunc(), which is a new method added in 2015. It returns the integral part of a number by removing any fractional digits.

function display(a){
  var hours = Math.trunc(a/60);
  var minutes = a % 60;
  console.log(hours +":"+ minutes);
}

display(120); //"2:0"
display(60); //"1:0:
display(100); //"1:40"
display(126); //"2:6"
display(45); //"0:45"

You can do in a very simple way. The idea is to place a Label in the same place as your textbox. Your Label will be visible if textbox has no text and hasn't the focus.

 <Label Name="PalceHolder"  HorizontalAlignment="Left" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Height="40" VerticalAlignment="Top" Width="239" FontStyle="Italic"  Foreground="BurlyWood">PlaceHolder Text Here
  <Label.Style>
    <Style TargetType="{x:Type Label}">
      <Setter Property="Visibility" Value="Hidden"/>
      <Style.Triggers>
        <MultiDataTrigger>
          <MultiDataTrigger.Conditions>
            <Condition Binding ="{Binding ElementName=PalceHolder, Path=Text.Length}" Value="0"/>
            <Condition Binding ="{Binding ElementName=PalceHolder, Path=IsFocused}" Value="False"/>
          </MultiDataTrigger.Conditions>
          <Setter Property="Visibility" Value="Visible"/>
        </MultiDataTrigger>
      </Style.Triggers>
    </Style>
  </Label.Style>
</Label>
<TextBox  Background="Transparent" Name="TextBox1" HorizontalAlignment="Left" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Height="40"TextWrapping="Wrap" Text="{Binding InputText,Mode=TwoWay}" VerticalAlignment="Top" Width="239" />

Bonus:If you want to have default value for your textBox, be sure after to set it when submitting data (for example:"InputText"="PlaceHolder Text Here" if empty).

MSDN says:

This delegate is used by the Array.ForEach method and the List.ForEach method to perform an action on each element of the array or list.

Except that, you can use it as a generic delegate that takes 1-3 parameters without returning any value.

Consider the following scenario:

public class Car {
  @Inject
  private Engine engine;  

  public Car() {
    engine.initialize();  
  }
  ...
}

Since Car has to be instantiated prior to field injection, the injection point engine is still null during the execution of the constructor, resulting in a NullPointerException.

This problem can be solved either by JSR-330 Dependency Injection for Java constructor injection or JSR 250 Common Annotations for the Java @PostConstruct method annotation.

@PostConstruct

JSR-250 defines a common set of annotations which has been included in Java SE 6.

The PostConstruct annotation is used on a method that needs to be executed after dependency injection is done to perform any initialization. This method MUST be invoked before the class is put into service. This annotation MUST be supported on all classes that support dependency injection.

JSR-250 Chap. 2.5 javax.annotation.PostConstruct

The @PostConstruct annotation allows for the definition of methods to be executed after the instance has been instantiated and all injects have been performed.

public class Car {
  @Inject
  private Engine engine;  

  @PostConstruct
  public void postConstruct() {
    engine.initialize();  
  }
  ...
} 

Instead of performing the initialization in the constructor, the code is moved to a method annotated with @PostConstruct.

The processing of post-construct methods is a simple matter of finding all methods annotated with @PostConstruct and invoking them in turn.

private  void processPostConstruct(Class type, T targetInstance) {
  Method[] declaredMethods = type.getDeclaredMethods();

  Arrays.stream(declaredMethods)
      .filter(method -> method.getAnnotation(PostConstruct.class) != null) 
      .forEach(postConstructMethod -> {
         try {
           postConstructMethod.setAccessible(true);
           postConstructMethod.invoke(targetInstance, new Object[]{});
        } catch (IllegalAccessException | IllegalArgumentException | InvocationTargetException ex) {      
          throw new RuntimeException(ex);
        }
      });
}

The processing of post-construct methods has to be performed after instantiation and injection have been completed.

matches method performs matching of full line, i.e. it is equivalent to find() with '^abc$'. So, just use Pattern.compile("[a-zA-Z]").matcher(str).find() instead. Then fix your regex. As @user unknown mentioned your regex actually matches only one character. You probably should say [a-zA-Z]+

In your case both are equivalent!

Synchronizing a static method is equivalent to a synchronized block on corresponding Class object.

In fact when you declare a synchronized static method lock is obtained on the monitor corresponding to the Class object.

public static synchronized int getCount() {
    // ...
}

is same as

public int getCount() {
    synchronized (ClassName.class) {
        // ...
    }
}

Both of these classes are smart pointers, which means that they automatically (in most cases) will deallocate the object that they point at when that object can no longer be referenced. The difference between the two is how many different pointers of each type can refer to a resource.

When using unique_ptr, there can be at most one unique_ptr pointing at any one resource. When that unique_ptr is destroyed, the resource is automatically reclaimed. Because there can only be one unique_ptr to any resource, any attempt to make a copy of a unique_ptr will cause a compile-time error. For example, this code is illegal:

unique_ptr<T> myPtr(new T);       // Okay
unique_ptr<T> myOtherPtr = myPtr; // Error: Can't copy unique_ptr

However, unique_ptr can be moved using the new move semantics:

unique_ptr<T> myPtr(new T);                  // Okay
unique_ptr<T> myOtherPtr = std::move(myPtr); // Okay, resource now stored in myOtherPtr

Similarly, you can do something like this:

unique_ptr<T> MyFunction() {
    unique_ptr<T> myPtr(/* ... */);

    /* ... */

    return myPtr;
}

This idiom means "I'm returning a managed resource to you. If you don't explicitly capture the return value, then the resource will be cleaned up. If you do, then you now have exclusive ownership of that resource." In this way, you can think of unique_ptr as a safer, better replacement for auto_ptr.

shared_ptr, on the other hand, allows for multiple pointers to point at a given resource. When the very last shared_ptr to a resource is destroyed, the resource will be deallocated. For example, this code is perfectly legal:

shared_ptr<T> myPtr(new T);       // Okay
shared_ptr<T> myOtherPtr = myPtr; // Sure!  Now have two pointers to the resource.

Internally, shared_ptr uses reference counting to track how many pointers refer to a resource, so you need to be careful not to introduce any reference cycles.

In short:

1. Use unique_ptr when you want a single pointer to an object that will be reclaimed when that single pointer is destroyed.
2. Use shared_ptr when you want multiple pointers to the same resource.

Hope this helps!

It depends on a server configuration. If you're working with PHP under Linux or similar, you can control it using .htaccess configuration file, like so:

#set max post size
php_value post_max_size 20M

And, yes, I can personally attest to the fact that this works :)

If you're using IIS, I don't have any idea how you'd set this particular value.

In Xcode 8 beta 4 does not work...

Use:

DispatchQueue.main.asyncAfter(deadline: .now() + 0.5) {
    print("Are we there yet?")
}

for async two ways:

DispatchQueue.main.async {
    print("Async1")
}

DispatchQueue.main.async( execute: {
    print("Async2")
})

Kinda old subject but I had same question a few days ago and I came up with another idea (maybe someone will still find it usefull)

For example you can make a config.bat with different subjects (family, size, color, animals) and apply them individually in any order anywhere you want in your batch scripts:

@echo off
rem Empty the variable to be ready for label config_all
set config_all_selected=

rem Go to the label with the parameter you selected
goto :config_%1

REM This next line is just to go to end of file 
REM in case that the parameter %1 is not set
goto :end

REM next label is to jump here and get all variables to be set
:config_all
set config_all_selected=1


:config_family
set mother=Mary
set father=John
set sister=Anna
rem This next line is to skip going to end if config_all label was selected as parameter
if not "%config_all_selected%"=="1" goto :end

:config_test
set "test_parameter_all=2nd set: The 'all' parameter WAS used before this echo"
if not "%config_all_selected%"=="1" goto :end

:config_size
set width=20
set height=40
if not "%config_all_selected%"=="1" goto :end


:config_color
set first_color=blue
set second_color=green
if not "%config_all_selected%"=="1" goto :end


:config_animals
set dog=Max
set cat=Miau
if not "%config_all_selected%"=="1" goto :end


:end

After that, you can use it anywhere by calling fully with 'call config.bat all' or calling only parts of it (see example bellow) The idea in here is that sometimes is more handy when you have the option not to call everything at once. Some variables maybe you don't want to be called yet so you can call them later.

Example test.bat

@echo off

rem This is added just to test the all parameter
set "test_parameter_all=1st set: The 'all' parameter was NOT used before this echo"

call config.bat size

echo My birthday present had a width of %width% and a height of %height%

call config.bat family
call config.bat animals

echo Yesterday %father% and %mother% surprised %sister% with a cat named %cat%
echo Her brother wanted the dog %dog%

rem This shows you if the 'all' parameter was or not used (just for testing)
echo %test_parameter_all%

call config.bat color

echo His lucky color is %first_color% even if %second_color% is also nice.

echo.
pause

Hope it helps the way others help me in here with their answers.

A short version of the above:

config.bat

@echo off
set config_all_selected=
goto :config_%1
goto :end

:config_all
set config_all_selected=1

:config_family
set mother=Mary
set father=John
set daughter=Anna
if not "%config_all_selected%"=="1" goto :end

:config_size
set width=20
set height=40
if not "%config_all_selected%"=="1" goto :end

:end

test.bat

@echo off

call config.bat size
echo My birthday present had a width of %width% and a height of %height%

call config.bat family
echo %father% and %mother% have a daughter named %daughter%

echo.
pause

Good day.

To keep it dynamic, just use:

(window as any).MyNamespace

You must use LEFT JOIN instead of INNER JOIN

SELECT person.person_id, COUNT(appointment.person_id) AS "number_of_appointments"
FROM person 
LEFT JOIN appointment ON person.person_id = appointment.person_id
GROUP BY person.person_id;

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

You can get around this problem by writing a custom function that uses curl, as in:

function file_get_contents_curl( $url ) {

  $ch = curl_init();

  curl_setopt( $ch, CURLOPT_AUTOREFERER, TRUE );
  curl_setopt( $ch, CURLOPT_HEADER, 0 );
  curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
  curl_setopt( $ch, CURLOPT_URL, $url );
  curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, TRUE );

  $data = curl_exec( $ch );
  curl_close( $ch );

  return $data;

}

Then just use file_get_contents_curl instead of file_get_contents whenever you're calling a url that begins with https.

You could also consider using getting the indexes of last elements in each specified dimensions using this as following;

int x = ary.GetUpperBound(0);
int y = ary.GetUpperBound(1);

Keep in mind that this gets the value of index as 0-based.

If you want all the bars to get the same color (fill), you can easily add it inside geom_bar.

ggplot(data=df, aes(x=c1+c2/2, y=c3)) + 
geom_bar(stat="identity", width=c2, fill = "#FF6666")

Add fill = the_name_of_your_var inside aes to change the colors depending of the variable :

c4 = c("A", "B", "C")
df = cbind(df, c4)
ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2)

Use scale_fill_manual() if you want to manually the change of colors.

ggplot(data=df, aes(x=c1+c2/2, y=c3, fill = c4)) + 
geom_bar(stat="identity", width=c2) + 
scale_fill_manual("legend", values = c("A" = "black", "B" = "orange", "C" = "blue"))

    using System;
    using System.IO.Ports;
    using System.Threading;

    namespace SerialReadTest
    {
        class SerialRead
        {
            static void Main(string[] args)
            {
        Console.WriteLine("Serial read init");
        SerialPort port = new SerialPort("COM6", 115200, Parity.None, 8, StopBits.One);
        port.Open();
        while(true){
          Console.WriteLine(port.ReadLine());
        }

    }
}
}

I have just include Maven integration plug-in with Eclipse:

Just follow the bellow steps:

In eclipse, from upper menu item select- Help ->click on Install New Software..-> then click on Add button.

set the MavenAPI at name text box and http://download.eclipse.org/technology/m2e/releases at location text box.

press OK and select the Maven project and install by clicking next.

They're examples provided by the Android team, if you've already loaded Samples, you can import Home screen replacement sample by following these steps.

File > New > Other >Android > Android Sample Project > Android x.x > Home > Finish

But if you do not have samples loaded, then download it using the below steps

Windows > Android SDK Manager > chooses "Sample for SDK" for SDK you need it > Install package > Accept License > Install

It is probably everything all right with your code/provisioning profiles/Xcode.

I did try once more, and it worked like a charm. I did not change anything.

Please take note that some actions of people replying earlier did take, could not have any effect on this problem but still, it might look like that actions did help. It would work with or without it anyway.

jeues answer helped me nothing :-( after hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

after that everything worked very well, even without any "-extension RANDR" switch.

Jquery UI Dialog Demos

I had been using the method in Jon Skeet's answer, but another one occurred to me using Concat. The Concat method performed slightly better in a limited test, but it's a hassle and I'll probably just stick with Contains, or maybe I'll write a helper method to do this for me. Either way, here's another option if anyone is interested:

The Method

// Given an array of id's
var ids = new Guid[] { ... };

// and a DataContext
var dc = new MyDataContext();

// start the queryable
var query = (
    from thing in dc.Things
    where thing.Id == ids[ 0 ]
    select thing 
);

// then, for each other id
for( var i = 1; i < ids.Count(); i++ ) {
    // select that thing and concat to queryable
    query.Concat(
        from thing in dc.Things
        where thing.Id == ids[ i ]
        select thing
    );
}

Performance Test

This was not remotely scientific. I imagine your database structure and the number of IDs involved in the list would have a significant impact.

I set up a test where I did 100 trials each of Concat and Contains where each trial involved selecting 25 rows specified by a randomized list of primary keys. I've run this about a dozen times, and most times the Concat method comes out 5 - 10% faster, although one time the Contains method won by just a smidgen.

The warning is indeed annoying and in many (most!) cases no contentDescription is necessary for various decorative ImageViews. The most radical way to solve the problem is just to tell the Lint to ignore this check. In Eclipse, go to "Android/Lint Error Checking" in Preferences, find "contentDescription" (it is in the "Accessibility" group) and change "Severity:" to Ignore.

Connection in APPConfig

<connectionStrings>
  <add name="ConnectionString" connectionString="Data Source=192.168.1.25;Initial Catalog=Login;Persist Security Info=True;User ID=sa;Password=example.com"   providerName="System.Data.SqlClient" />
</connectionStrings>

In Class.Cs

public string ConnectionString
{
    get
    {
        return System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ToString();
    }
}

I believe what you want is:

SELECT ItemName, GROUP_CONCAT(DepartmentId) FROM table_name GROUP BY ItemName

In Powershell 5 escaping double quotes can be done by backtick (`). But sometimes you need to provide your double quotes escaped which can be done by backslash + backtick (\`). Eg in this curl call:

C:\Windows\System32\curl.exe -s -k -H "Content-Type: application/json" -XPOST localhost:9200/index_name/inded_type -d"{\`"velocity\`":3.14}"

Since this is a popular question, I would like to add that in Elasticsearch version 2 things changed a bit.

Instead of filtered query, one should use bool query in the top level.

If you don't care about the score of must parts, then put those parts into filter key. No scoring means faster search. Also, Elasticsearch will automatically figure out, whether to cache them, etc. must_not is equally valid for caching.

Reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html

Also, mind that "gte": "now" cannot be cached, because of millisecond granularity. Use two ranges in a must clause: one with now/1h and another with now so that the first can be cached for a while and the second for precise filtering accelerated on a smaller result set.

query runs a standard SQL statement and requires you to properly escape all data to avoid SQL Injections and other issues.

execute runs a prepared statement which allows you to bind parameters to avoid the need to escape or quote the parameters. execute will also perform better if you are repeating a query multiple times. Example of prepared statements:

$sth = $dbh->prepare('SELECT name, colour, calories FROM fruit
    WHERE calories < :calories AND colour = :colour');
$sth->bindParam(':calories', $calories);
$sth->bindParam(':colour', $colour);
$sth->execute();
// $calories or $color do not need to be escaped or quoted since the
//    data is separated from the query

Best practice is to stick with prepared statements and execute for increased security.

See also: Are PDO prepared statements sufficient to prevent SQL injection?

Lifecycle hooks, like OnInit() work with Directives and Components. They do not work with other types, like a service in your case. From docs:

A Component has a lifecycle managed by Angular itself. Angular creates it, renders it, creates and renders its children, checks it when its data-bound properties change and destroy it before removing it from the DOM.

Directive and component instances have a lifecycle as Angular creates, updates, and destroys them.

There are three tables- Equities(coulmns: ID,ISIN) and Bond(coulmns: ID,ISIN). Third table Securities(coulmns: ID,ISIN) contains all data from Equities and Bond tables. Write SQL queries to validate below: (1) Securities table should contain all the data from Equities and Bonds tables. (2) Securities table should not contain any data other than present in Equities and Bonds tables

You can use Environment.Exit(0); and Application.Exit

Environment.Exit(0) is cleaner.

What I did was download my sql dump in a "db-dump" folder, and mounted it:

mysql:
 image: mysql:5.6
 environment:
   MYSQL_ROOT_PASSWORD: pass
 ports:
   - 3306:3306
 volumes:
   - ./db-dump:/docker-entrypoint-initdb.d

When I run docker-compose up for the first time, the dump is restored in the db.

So if the issue is you just created a website and your clients or any given ISP DNS is cached and doesn't show new site yet. Yes all the other stuff applies ipconfig reset browser etc. BUT here's an Idea and something I do from time to time. You can set an alternate network ISP's DNS in the tcpip properties on the NIC properties. So if your ISP is say telstra and it hasn't propagated or updated you can specify an alternate service providers dns there. if that isp dns is updated before your native one hey presto you will see new site.But there is lots of other tricks you can do to determine propagation and get mail to work prior to the DNS updating. drop me a line if any one wants to chat.

Here is my version:

/**
 * 
 * Insert an element after an index in an array
 * @param array $array  
 * @param string|int $key 
 * @param mixed $value
 * @param string|int $offset
 * @return mixed
 */
function array_splice_associative($array, $key, $value, $offset) {
    if (!is_array($array)) {
        return $array;
    }
    if (array_key_exists($key, $array)) {
        unset($array[$key]);
    }
    $return = array();
    $inserted = false;
    foreach ($array as $k => $v) {
        $return[$k] = $v;
        if ($k == $offset && !$inserted) {
            $return[$key] = $value;
            $inserted = true;
        }
    }
    if (!$inserted) {
        $return[$key] = $value;
    }


    return $return;
}

You may also want to make sure that your code localizes correctly, or make sure the users are used to the "international" notation. For example, "1,112" actually means different numbers across different countries. In Germany it means the number a little over one, instead of one thousand and something.

Corresponding Wikipedia article is at http://en.wikipedia.org/wiki/Decimal_mark. It seems to be poorly written at this time though. For example as a Chinese I'm not sure where does these description about thousand separator in China come from.

I think the problem you're running into is that, even though you can set your own umask values in the system, this does not allow you to explicitly control the default permissions set on a new file by gedit (or whatever editor you use).

I believe this detail is hard-coded into gedit and most other editors. Your options for changing it are (a) hacking up your own mod of gedit or (b) finding a text editor that allows you to set a preference for default permissions on new files. (Sorry, I know of none.)

In light of this, it's really not so bad to have to chmod your files, right?

When [dropping] the encoding settings mentioned above all characters [are rendered] correctly but the encoding that is detected shows either windows-1252 or ISO-8859-1 depending on the browser.

Then that's what you're really sending. None of the encoding settings in your bullet list will actually modify your output in any way; all they do is tell the browser what encoding to assume when interpreting what you send. That's why you're getting those ?s - you're telling the browser that what you're sending is UTF-8, but it's really ISO-8859-1.

@John Woo's accepted answer has some caveats which you should be aware of:

1. Default language setting of a session is controlled from default language setting of the user login instead which you have used to create the session. SQL Server instance level setting doesn't affect the default language of the session.
2. Changing default language setting at SQL Server instance level doesn't affects the default language setting of the existing SQL Server logins. It is meant to be inherited only by the new user logins that you create after changing the instance level setting.

So, there is an intermediate level between your SQL Server instance and the session which you can use to control the default language setting for session - login level.

SQL Server Instance level setting -> User login level setting -> Query Session level setting

This can help you in case you want to set default language of all new sessions belonging to some specific user only.

Simply change the default language setting of the target user login as per this link and you are all set. You can also do it from SQL Server Management Studio (SSMS) UI. Below you can see the default language setting in properties window of sa user in SQL Server:

Note: Also, it is important to know that changing the setting doesn't affect the default language of already active sessions from that user login. It will affect only the new sessions created after changing the setting.
