mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

These are deprecated use the following..

 // Connects to your Database
            $link = mysqli_connect("localhost", "root", "", "");

and to insert data use the following

 $sql = "INSERT INTO  Table-Name (Column-Name)
VALUES ('$filename')" ;

I don't know whether there's a better answer out there as time goes by but this is simple and it works;

input[type='email'] {
  background: white url(images/mail.svg) no-repeat ;
}
input[type='email']:focus {
  background-image: none;
}

Style it up to suit.

No. Go to database tools (for 2007) and click checkmark on the Message Bar. Then, after the message bar apears, click on Options, and then Enable. Hope this helps.

This is useful when you have more than one class to append. You can join all classes in array with a space.

const visibility = this.props.showBulkActions ? "show" : ""
<div className={["btn-group pull-right", visibility].join(' ')}>

To simplify: Only configuration files can access environment variables - and then pass them on.

Step 1.) Add your variable to your .env file, for example,

EXAMPLE_URL="http://google.com"

Step 2.) Create a new file inside of the config folder, with any name, for example,

config/example.php

Step 3.) Inside of this new file, I add an array being returned, containing that environment variable.

<?php
return [
  'url' => env('EXAMPLE_URL')
];

Step 4.) Because I named it "example", my configuration 'namespace' is now example. So now, in my controller I can access this variable with:

$url = \config('example.url');

Tip - if you add use Config; at the top of your controller, you don't need the backslash (which designates the root namespace). For example,

namespace App\Http\Controllers;
use Config; // Added this line

class ExampleController extends Controller
{
    public function url() {
        return config('example.url');
    }
}

Finally, commit the changes:

php artisan config:cache

--- IMPORTANT --- Remember to enter php artisan config:cache into the console once you have created your example.php file. Configuration files and variables are cached, so if you make changes you need to flush that cache - the same applies to the .env file being changed / added to.

Its as simple as this:

CREATE FUNCTION InlineMax
(
    @p1 sql_variant,
    @p2 sql_variant
)  RETURNS sql_variant
AS
BEGIN
    RETURN CASE 
        WHEN @p1 IS NULL AND @p2 IS NOT NULL THEN @p2 
        WHEN @p2 IS NULL AND @p1 IS NOT NULL THEN @p1
        WHEN @p1 > @p2 THEN @p1
        ELSE @p2 END
END;

You are trying to group code according to struct. C grouping is by file. You put all the functions and internal variables in a header or a header and a object ".o" file compiled from a c source file.

It is not necessary to reinvent object-orientation from scratch for a C program, which is not an object oriented language.

I have seen this before. It is a strange thing. Coders, some of them, have an aversion to passing an object they want to change into a function to change it, even though that is the standard way to do so.

I blame C++, because it hid the fact that the class object is always the first parameter in a member function, but it is hidden. So it looks like it is not passing the object into the function, even though it is.

Client.addClient(Client& c); // addClient first parameter is actually 
                             // "this", a pointer to the Client object.

C is flexible and can take passing things by reference.

A C function often returns only a status byte or int and that is often ignored. In your case a proper form might be

 err = addClient( container_t  cnt, client_t c);
 if ( err != 0 )
   { fprintf(stderr, "could not add client (%d) \n", err ); 

addClient would be in Client.h or Client.c

URL url = new URL(yourUrl, "/api/v1/status.xml");

According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:

URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

Sources: http://docs.oracle.com/javase/6/docs/api/java/net/URL.html

dir /s/d/a:-d "folderpath*.*" > file.txt

And, lose the /s if you do not need files from subfolders

An alternative way is to use MySql Workbench. Go to Administration -> Users and privileges -> and change 'localhost' with '%' in 'Limit to Host Matching' (From host) attribute for users you wont to give remote access Or create new user ( Add account button ) with '%' on this attribute instead localhost.

This isn't exactly what you are looking for but here is how I've approached this problem in the past;

You can enter a formula like;

=COUNTIF(A1:A10,"Green")

...into a cell. This will count the Number of cells between A1 and A10 that contain the text "Green". You can then select this cell value in a VBA Macro and assign it to a variable as normal.

You can use this method to log the exception stack to String

 public String stackTraceToString(Throwable e) {
    StringBuilder sb = new StringBuilder();
    for (StackTraceElement element : e.getStackTrace()) {
        sb.append(element.toString());
        sb.append("\n");
    }
    return sb.toString();
}

For me the issues was I had the key and cert swapped.

var options = {
   key: fs.readFileSync('/etc/letsencrypt/live/mysite.com/privkey.pem'),
   cert: fs.readFileSync('/etc/letsencrypt/live/mysite.com/fullchain.pem'),
   ca: fs.readFileSync('/etc/letsencrypt/live/mysite.com/chain.pem')
};

I have created a repo on github including a more complete version of the above code if anyone is interested: https://github.com/snowballrandom/Memcached-Auth

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

This is the most exhaustive answer so far and gets rid of the need for a $i variable floating around. It is a combo of Kip and Gnarf's answers.

$array = array( 'cat' => 'meow', 'dog' => 'woof', 'cow' => 'moo', 'computer' => 'beep' );
foreach( array_keys( $array ) as $index=>$key ) {

    // display the current index + key + value
    echo $index . ':' . $key . $array[$key];

    // first index
    if ( $index == 0 ) {
        echo ' -- This is the first element in the associative array';
    }

    // last index
    if ( $index == count( $array ) - 1 ) {
        echo ' -- This is the last element in the associative array';
    }
    echo '<br>';
}

Hope it helps someone.

Note : Throw any defined exception other than Exception()

As the question is asked years ago, and Android is evolved a lot on this URI scheme.
From original URI scheme, to deep link, and now Android App Links.

Android now recommends to use HTTP URLs, not define your own URI scheme. Because Android App Links use HTTP URLs that link to a website domain you own, so no other app can use your links. You can check the comparison of deep link and Android App links from here

Now you can easily add a URI scheme by using Android Studio option: Tools > App Links Assistant. Please refer the detail to Android document: https://developer.android.com/studio/write/app-link-indexing.html

About the .dex File :

One of the most remarkable features of the Dalvik Virtual Machine (the workhorse under the Android system) is that it does not use Java bytecode. Instead, a homegrown format called DEX was introduced and not even the bytecode instructions are the same as Java bytecode instructions.

Compiled Android application code file.

Android programs are compiled into .dex (Dalvik Executable) files, which are in turn zipped into a single .apk file on the device. .dex files can be created by automatically translating compiled applications written in the Java programming language.

Dex file format:

 1. File Header
 2. String Table
 3. Class List
 4. Field Table
 5. Method Table
 6. Class Definition Table
 7. Field List
 8. Method List
 9. Code Header
10. Local Variable List

Android has documentation on the Dalvik Executable Format (.dex files). You can find out more over at the official docs: Dex File Format

.dex files are similar to java class files, but they were run under the Dalkvik Virtual Machine (DVM) on older Android versions, and compiled at install time on the device to native code with ART on newer Android versions.

You can decompile .dex using the dexdump tool which is provided in android-sdk.

There are also some Reverse Engineering Techniques to make a jar file or java class file from a .dex file.

Java doesn't have the concept of optional parameters with default values either in constructors or in methods. You're basically stuck with overloading. However, you chain constructors easily so you don't need to repeat the code:

public Foo(int param1, int param2)
{
    this.param1 = param1;
    this.param2 = param2;
}

public Foo(int param1)
{
    this(param1, 2);
}

You can find those maven properties in the super pom.

You find the jar here:

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

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

Navigate to

org/apache/maven/model

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

It contains all those "short cuts":

<project>
    ...
    <build>
        <directory>${project.basedir}/target</directory>
        <outputDirectory>${project.build.directory}/classes</outputDirectory>
        <finalName>${project.artifactId}-${project.version}</finalName>
        <testOutputDirectory>${project.build.directory}/test-classes</testOutputDirectory>
        <sourceDirectory>${project.basedir}/src/main/java</sourceDirectory>
        <scriptSourceDirectory>src/main/scripts</scriptSourceDirectory>
        <testSourceDirectory>${project.basedir}/src/test/java</testSourceDirectory>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
            </resource>
        </resources>
        <testResources>
            <testResource>
                <directory>${project.basedir}/src/test/resources</directory>
            </testResource>
        </testResources>
        ...
    </build>
    ...
</project>

Update

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

In case of writing in python3

>>> a = u'bats\u00E0'
>>> print a
batsà
>>> f = open("/tmp/test", "w")
>>> f.write(a)
>>> f.close()
>>> data = open("/tmp/test").read()
>>> data
'batsà'

In case of writing in python2:

>>> a = u'bats\u00E0'
>>> f = open("/tmp/test", "w")
>>> f.write(a)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe0' in position 4: ordinal not in range(128)

To avoid this error you would have to encode it to bytes using codecs "utf-8" like this:

>>> f.write(a.encode("utf-8"))
>>> f.close()

and decode the data while reading using the codecs "utf-8":

>>> data = open("/tmp/test").read()
>>> data.decode("utf-8")
u'bats\xe0'

And also if you try to execute print on this string it will automatically decode using the "utf-8" codecs like this

>>> print a
batsà

Ryley's answer is great, but I have text within the element. In order to rotate the text along with everything else, I used the border-spacing property instead of text-indent.

Also, to clarify a bit, in the element's style, set your initial value:

#foo {
    border-spacing: 0px;
}

Then in the animate chunk, your final value:

$('#foo').animate({  borderSpacing: -90 }, {
    step: function(now,fx) {
      $(this).css('transform','rotate('+now+'deg)');  
    },
    duration:'slow'
},'linear');

In my case, it rotates 90 degrees counter-clockwise.

Here is the live demo.

The expression stringexpression = '' yields:

TRUE   .. for '' (or for any string consisting of only spaces with the data type char(n))
NULL   .. for NULL
FALSE .. for anything else

So to check for: "stringexpression is either NULL or empty":

(stringexpression = '') IS NOT FALSE

Or the reverse approach (may be easier to read):

(stringexpression <> '') IS NOT TRUE

Works for any character type including char(n). The manual about comparison operators.

Or use your original expression without trim(), which is costly noise for char(n) (see below), or incorrect for other character types: strings consisting of only spaces would pass as empty string.

coalesce(stringexpression, '') = ''

But the expressions at the top are faster.

Asserting the opposite is even simpler: "stringexpression is neither NULL nor empty":

stringexpression <> ''

About char(n)

This is about the data type char(n), short for: character(n). (char / character are short for char(1) / character(1).) Its use is discouraged in Postgres:

In most situations text or character varying should be used instead.

Do not confuse char(n) with other, useful, character types varchar(n), varchar, text or "char" (with double-quotes).

In char(n) an empty string is not different from any other string consisting of only spaces. All of these are folded to n spaces in char(n) per definition of the type. It follows logically that the above expressions work for char(n) as well - just as much as these (which wouldn't work for other character types):

coalesce(stringexpression, '  ') = '  '
coalesce(stringexpression, '') = '       '

Demo

Empty string equals any string of spaces when cast to char(n):

SELECT ''::char(5) = ''::char(5)     AS eq1
     , ''::char(5) = '  '::char(5)   AS eq2
     , ''::char(5) = '    '::char(5) AS eq3;

Result:

 eq1 | eq2 | eq3
 ----+-----+----
 t   | t   | t

Test for "null or empty string" with char(n):

SELECT stringexpression 
     , stringexpression = ''                   AS base_test
     , (stringexpression = '')  IS NOT FALSE   AS test1
     , (stringexpression <> '') IS NOT TRUE    AS test2
     , coalesce(stringexpression, '') = ''     AS coalesce1
     , coalesce(stringexpression, '  ') = '  ' AS coalesce2
     , coalesce(stringexpression, '') = '  '   AS coalesce3
FROM  (
   VALUES
     ('foo'::char(5))
   , ('')
   , ('   ')                -- not different from '' in char(n)
   , (NULL)
   ) sub(stringexpression);

Result:

 stringexpression | base_test | test1 | test2 | coalesce1 | coalesce2 | coalesce3 
------------------+-----------+-------+-------+-----------+-----------+-----------

                  | t         | t     | t     | t         | t         | t
 null             | null      | t     | t     | t         | t         | t

Test for "null or empty string" with text:

SELECT stringexpression 
     , stringexpression = ''                   AS base_test
     , (stringexpression = '')  IS NOT FALSE   AS test1
     , (stringexpression <> '') IS NOT TRUE    AS test2
     , coalesce(stringexpression, '') = ''     AS coalesce1
     , coalesce(stringexpression, '  ') = '  ' AS coalesce2
     , coalesce(stringexpression, '') = '  '   AS coalesce3
FROM  (
   VALUES
     ('foo'::text)
   , ('')
   , ('   ')                -- different from '' in a sane character types
   , (NULL)
   ) sub(stringexpression);

Result:

• Any downsides of using data type "text" for storing strings?

I had this problem and then I ran "apache_start.bat" the error in german told me there was a problem with line 51 in httpd-ssl.conf which is

SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5

What I did was comment lines 163 (ssl module) and 522 (httpd-ssl.conf include) in httpd.conf; I don't need ssl for development, so that solved it for me.

If you are using Visual Studio, there is a GUI solution as well:

1. From Toolbox add a ContextMenuStrip
2. Select the context menu and add the right click items
3. For each item set the click events to the corresponding functions
4. Select the form / button / image / etc (any item) that the right click menu will be connected
5. Set its ContextMenuStrip property to the menu you have created.

This is shorter and works

<connectionStrings>      
<add name="DBConnection"
             connectionString="data source=SERVER\INSTANCE;
       Initial Catalog=MyDB;Integrated Security=SSPI;"
             providerName="System.Data.SqlClient" />
</connectionStrings> 

Persist Security Info not needed

I faced the error,
problem was FORM METHOD

{{ Form::open(array('url' => 'admin/doctor/edit/'.$doctor->doctor_id,'class'=>'form-horizontal form-bordered form-row-stripped','method' => 'PUT','files'=>true)) }}

It should be like this

{{ Form::open(array('url' => 'admin/doctor/edit/'.$doctor->doctor_id,'class'=>'form-horizontal form-bordered form-row-stripped','method' => 'POST','files'=>true)) }}

You can do it in a hackish way. Careful using the sqlcmd hack. If the data has double quotes or commas you will run into trouble.

You can use a simple script to do it properly:

As, you mentioned pContext.getParent().getPropertyValue return Set. You can convert Set to List to get the first element. Just change your code like:

 Set<String> siteIdSet = (Set<String>) pContext.getParent().getPropertyValue(..);
 List<String> siteIdList=new ArrayList<>(siteIdSet);

 String firstItem=siteIdList.get(0);

You can track by $index if your data source has duplicate identifiers

e.g.: $scope.dataSource: [{id:1,name:'one'}, {id:1,name:'one too'}, {id:2,name:'two'}]

You can't iterate this collection while using 'id' as identifier (duplicate id:1).

WON'T WORK:

<element ng-repeat="item.id as item.name for item in dataSource">
  // something with item ...
</element>

but you can, if using track by $index:

<element ng-repeat="item in dataSource track by $index">
  // something with item ...
</element>

const formatDate = d => [
    d.getFullYear(),
    (d.getMonth() + 1).toString().padStart(2, '0'),
    d.getDate().toString().padStart(2, '0')
].join('-');

You can make use of padstart.

padStart(n, '0') ensures that a minimum of n characters are in a string and prepends it with '0's until that length is reached.

join('-') concatenates an array, adding '-' symbol between every elements.

getMonth() starts at 0 hence the +1.

Add bluetooth permission to your AndroidManifest,

<uses-permission android:name="android.permission.BLUETOOTH" />

Then use intent filters to listen to the ACTION_ACL_CONNECTED, ACTION_ACL_DISCONNECT_REQUESTED, and ACTION_ACL_DISCONNECTED broadcasts:

public void onCreate() {
    ...
    IntentFilter filter = new IntentFilter();
    filter.addAction(BluetoothDevice.ACTION_ACL_CONNECTED);
    filter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED);
    filter.addAction(BluetoothDevice.ACTION_ACL_DISCONNECTED);
    this.registerReceiver(mReceiver, filter);
}

//The BroadcastReceiver that listens for bluetooth broadcasts
private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        BluetoothDevice device = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

        if (BluetoothDevice.ACTION_FOUND.equals(action)) {
           ... //Device found
        }
        else if (BluetoothDevice.ACTION_ACL_CONNECTED.equals(action)) {
           ... //Device is now connected
        }
        else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
           ... //Done searching
        }
        else if (BluetoothDevice.ACTION_ACL_DISCONNECT_REQUESTED.equals(action)) {
           ... //Device is about to disconnect
        }
        else if (BluetoothDevice.ACTION_ACL_DISCONNECTED.equals(action)) {
           ... //Device has disconnected
        }           
    }
};

A few notes:

• There is no way to retrieve a list of connected devices at application startup. The Bluetooth API does not allow you to QUERY, instead it allows you to listen to CHANGES.
• A hoaky work around to the above problem would be to retrieve the list of all known/paired devices... then trying to connect to each one (to determine if you're connected).
• Alternatively, you could have a background service watch the Bluetooth API and write the device states to disk for your application to use at a later date.

The answer comes from the javadoc of ZoneId (emphasis mine) ...

A ZoneId is used to identify the rules used to convert between an Instant and a LocalDateTime. There are two distinct types of ID:

• Fixed offsets - a fully resolved offset from UTC/Greenwich, that uses the same offset for all local date-times
• Geographical regions - an area where a specific set of rules for finding the offset from UTC/Greenwich apply

Most fixed offsets are represented by ZoneOffset. Calling normalized() on any ZoneId will ensure that a fixed offset ID will be represented as a ZoneOffset.

... and from the javadoc of ZoneId#of (emphasis mine):

This method parses the ID producing a ZoneId or ZoneOffset. A ZoneOffset is returned if the ID is 'Z', or starts with '+' or '-'.

The argument id is specified as "UTC", therefore it will return a ZoneId with an offset, which also presented in the string form:

System.out.println(now.withZoneSameInstant(ZoneOffset.UTC));
System.out.println(now.withZoneSameInstant(ZoneId.of("UTC")));

Outputs:

2017-03-10T08:06:28.045Z
2017-03-10T08:06:28.045Z[UTC]

As you use the equals method for comparison, you check for object equivalence. Because of the described difference, the result of the evaluation is false.

When the normalized() method is used as proposed in the documentation, the comparison using equals will return true, as normalized() will return the corresponding ZoneOffset:

Normalizes the time-zone ID, returning a ZoneOffset where possible.

now.withZoneSameInstant(ZoneOffset.UTC)
    .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())); // true

As the documentation states, if you use "Z" or "+0" as input id, of will return the ZoneOffset directly and there is no need to call normalized():

now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("Z"))); //true
now.withZoneSameInstant(ZoneOffset.UTC).equals(now.withZoneSameInstant(ZoneId.of("+0"))); //true

To check if they store the same date time, you can use the isEqual method instead:

now.withZoneSameInstant(ZoneOffset.UTC)
    .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))); // true

Sample

System.out.println("equals - ZoneId.of(\"UTC\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC"))));
System.out.println("equals - ZoneId.of(\"UTC\").normalized(): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("UTC").normalized())));
System.out.println("equals - ZoneId.of(\"Z\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("Z"))));
System.out.println("equals - ZoneId.of(\"+0\"): " + nowZoneOffset
        .equals(now.withZoneSameInstant(ZoneId.of("+0"))));
System.out.println("isEqual - ZoneId.of(\"UTC\"): "+ nowZoneOffset
        .isEqual(now.withZoneSameInstant(ZoneId.of("UTC"))));

Output:

equals - ZoneId.of("UTC"): false
equals - ZoneId.of("UTC").normalized(): true
equals - ZoneId.of("Z"): true
equals - ZoneId.of("+0"): true
isEqual - ZoneId.of("UTC"): true

Both the answers provided above work fine.

1. CREATE TABLE person AS select * from employee;
2. CREATE TABLE person LIKE employee;

See this fiddle for a preview and check the documentation for jquerys toggle and animate methods.

$('#toggle').toggle(function(){
    $('#A').animate({width:0});
    $('#B').animate({left:0});
},function(){
    $('#A').animate({width:200});
    $('#B').animate({left:200});
});

Basically you animate on the properties that sets the layout.

A more advanced version:

$('#toggle').toggle(function(){
    $('#A').stop(true).animate({width:0});
    $('#B').stop(true).animate({left:0});
},function(){
    $('#A').stop(true).animate({width:200});
    $('#B').stop(true).animate({left:200});
})

This stops the previous animation, clears animation queue and begins the new animation.

Jasypt provides the org.jasypt.properties.EncryptableProperties class for loading, managing and transparently decrypting encrypted values in .properties files, allowing the mix of both encrypted and not-encrypted values in the same file.

http://www.jasypt.org/encrypting-configuration.html

By using an org.jasypt.properties.EncryptableProperties object, an application would be able to correctly read and use a .properties file like this:

datasource.driver=com.mysql.jdbc.Driver 
datasource.url=jdbc:mysql://localhost/reportsdb 
datasource.username=reportsUser 
datasource.password=ENC(G6N718UuyPE5bHyWKyuLQSm02auQPUtm) 

Note that the database password is encrypted (in fact, any other property could also be encrypted, be it related with database configuration or not).

How do we read this value? like this:

/*
* First, create (or ask some other component for) the adequate encryptor for   
* decrypting the values in our .properties file.   
*/  
StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();     
encryptor.setPassword("jasypt"); // could be got from web, env variable...    
/*   
* Create our EncryptableProperties object and load it the usual way.   
*/  
Properties props = new EncryptableProperties(encryptor);  
props.load(new FileInputStream("/path/to/my/configuration.properties"));

/*   
* To get a non-encrypted value, we just get it with getProperty...   
*/  
String datasourceUsername = props.getProperty("datasource.username");

/*   
* ...and to get an encrypted value, we do exactly the same. Decryption will   
* be transparently performed behind the scenes.   
*/ 
String datasourcePassword = props.getProperty("datasource.password");

 // From now on, datasourcePassword equals "reports_passwd"...

You are correct, memory is automatically freed when the process exits. Some people strive not to do extensive cleanup when the process is terminated, since it will all be relinquished to the operating system. However, while your program is running you should free unused memory. If you don't, you may eventually run out or cause excessive paging if your working set gets too big.

window.location.href.split("#")[0].split("?")[0]

If you already have the xml, and comes more than one attribute, you can handle it as follows:

String output = "<ciudads><ciudad><idCiudad>1</idCiudad>
<nomCiudad>BOGOTA</nomCiudad></ciudad><ciudad><idCiudad>6</idCiudad>
<nomCiudad>Pereira</nomCiudad></ciudads>";
DocumentBuilder db = DocumentBuilderFactory.newInstance()
    .newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(output));

Document doc = db.parse(is);
NodeList nodes = ((org.w3c.dom.Document) doc)
    .getElementsByTagName("ciudad");

for (int i = 0; i < nodes.getLength(); i++) {           
    Ciudad ciudad = new Ciudad();
    Element element = (Element) nodes.item(i);

    NodeList name = element.getElementsByTagName("idCiudad");
    Element element2 = (Element) name.item(0);
    ciudad.setIdCiudad(Integer
        .valueOf(getCharacterDataFromElement(element2)));

    NodeList title = element.getElementsByTagName("nomCiudad");
    element2 = (Element) title.item(0);
    ciudad.setNombre(getCharacterDataFromElement(element2));

    ciudades.getPartnerAccount().add(ciudad);
}
}

for (Ciudad ciudad1 : ciudades.getPartnerAccount()) {
System.out.println(ciudad1.getIdCiudad());
System.out.println(ciudad1.getNombre());
}

the method getCharacterDataFromElement is

public static String getCharacterDataFromElement(Element e) {
Node child = e.getFirstChild();
if (child instanceof CharacterData) {
CharacterData cd = (CharacterData) child;

return cd.getData();
}
return "";
}

Sending an HTTP POST request using file_get_contents is not that hard, actually : as you guessed, you have to use the $context parameter.

There's an example given in the PHP manual, at this page : HTTP context options (quoting) :

$postdata = http_build_query(
    array(
        'var1' => 'some content',
        'var2' => 'doh'
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-Type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context  = stream_context_create($opts);

$result = file_get_contents('http://example.com/submit.php', false, $context);

Basically, you have to create a stream, with the right options (there is a full list on that page), and use it as the third parameter to file_get_contents -- nothing more ;-)

As a sidenote : generally speaking, to send HTTP POST requests, we tend to use curl, which provides a lot of options an all -- but streams are one of the nice things of PHP that nobody knows about... too bad...

Put this in your MainActivity:

{
    public EditText bizname, storeno, rcpt, item, price, tax, total;
    public Button click, click2;
    int contentView;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate( savedInstanceState );
        setContentView( R.layout.main_activity );
        bizname = (EditText) findViewById( R.id.editBizName );
        item = (EditText) findViewById( R.id.editItem );
        price = (EditText) findViewById( R.id.editPrice );
        tax = (EditText) findViewById( R.id.editTax );
        total = (EditText) findViewById( R.id.editTotal );
        click = (Button) findViewById( R.id.button );
    }
}

Put this under a button or something

public void clickBusiness(View view) {
    checkPermsOfStorage( this );

    bizname = (EditText) findViewById( R.id.editBizName );
    item = (EditText) findViewById( R.id.editItem );
    price = (EditText) findViewById( R.id.editPrice );
    tax = (EditText) findViewById( R.id.editTax );
    total = (EditText) findViewById( R.id.editTotal );
    String x = ("\nItem/Price: " + item.getText() + price.getText() + "\nTax/Total" + tax.getText() + total.getText());
    Toast.makeText( this, x, Toast.LENGTH_SHORT ).show();
    try {
        this.WriteBusiness(bizname,storeno,rcpt,item,price,tax,total);
        String vv = tax.getText().toString();
        System.console().printf( "%s", vv );
        //new XMLDivisionWriter(getString(R.string.SDDoc) + "/tax_div_business.xml");
    } catch (ReflectiveOperationException e) {
        e.printStackTrace();
    }
}

There! The debate is settled!

Use -1 as the start position:

INSTR('JD-EQ-0001', '-', -1)

I would like to propose the usage of string templates. Just place the string to be replaced in a dictionary and all is set! Example from docs.python.org

>>> from string import Template
>>> s = Template('$who likes $what')
>>> s.substitute(who='tim', what='kung pao')
'tim likes kung pao'
>>> d = dict(who='tim')
>>> Template('Give $who $100').substitute(d)
Traceback (most recent call last):
[...]
ValueError: Invalid placeholder in string: line 1, col 10
>>> Template('$who likes $what').substitute(d)
Traceback (most recent call last):
[...]
KeyError: 'what'
>>> Template('$who likes $what').safe_substitute(d)
'tim likes $what'

If they weren't in a static initialization block, where would they be? How would you declare a variable which was only meant to be local for the purposes of initialization, and distinguish it from a field? For example, how would you want to write:

public class Foo {
    private static final int widgets;

    static {
        int first = Widgets.getFirstCount();
        int second = Widgets.getSecondCount();
        // Imagine more complex logic here which really used first/second
        widgets = first + second;
    }
}

If first and second weren't in a block, they'd look like fields. If they were in a block without static in front of it, that would count as an instance initialization block instead of a static initialization block, so it would be executed once per constructed instance rather than once in total.

Now in this particular case, you could use a static method instead:

public class Foo {
    private static final int widgets = getWidgets();

    static int getWidgets() {
        int first = Widgets.getFirstCount();
        int second = Widgets.getSecondCount();
        // Imagine more complex logic here which really used first/second
        return first + second;
    }
}

... but that doesn't work when there are multiple variables you wish to assign within the same block, or none (e.g. if you just want to log something - or maybe initialize a native library).

Similar to Juice007, I had declared and initialized a C type variable in two different .m files (that weren't imported!)

BOOL myVar = NO;

however, this method of declaring and initializing a variable, even in .m, even in @implementation grants it global scope. Your options are:

1. Declare it as static, to limit the scope to class:

   static BOOL myVar = NO;
   

2. Remove the initialization (which will make the two classes share the global var):

   BOOL myVar;
   -(void) init{
       myVar = NO;
   }
   

3. Declare it as a property:

   @property BOOL myVar;
   

4. Declare it as a proper iVar in the @interface

   @interface myClass(){
       BOOL myVar;
   }
   @end
   

Wow, you have a huge misunderstanding how asp.net works.

This line of code

System.Diagnostics.Process.Start("help/AdminTutorial.html");

Will not redirect a admin user to a new site, but start a new process on the server (usually a browser, IE) and load the site. That is for sure not what you want.

A very easy solution would be to change the href attribute of the link in you page_load method.

Your aspx code:

<a href="#" runat="server" id="myLink">Tutorial</a>

Your codebehind / cs code of page_load:

...
if (userinfo.user == "Admin")
{
  myLink.Attributes["href"] = "help/AdminTutorial.html";
}
else 
{
  myLink.Attributes["href"] = "help/otherSite.html";
}
...

Don't forget to check the Admin rights again on "AdminTutorial.html" to "prevent" hacking.

If using mvn, check that you have the correct scope (if you have that defined) in your pom.xml. I once had it incorrectly set to test but needed it for runtime.

You may want to build a virtualenv of python3, then install packages of python3 after activating the virtualenv. So your system won't be messed up :)

This could be something like:

virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
pip install package-name

Just an alternative that I came up with to extract an extension, using the posts in this thread with my own small knowledge base that was more familiar to me.

ext="$(rev <<< "$(cut -f "1" -d "." <<< "$(rev <<< "file.docx")")")"

Note: Please advise on my use of quotes; it worked for me but I might be missing something on their proper use (I probably use too many).

    Comparator<Integer> comparator = new Comparator<Integer>() {

        @Override
        public int compare(Integer o1, Integer o2) {
            return o2.compareTo(o1);
        }
    };

    // option 1
    Integer[] array = new Integer[] { 1, 24, 4, 4, 345 };
    Arrays.sort(array, comparator);

    // option 2
    int[] array2 = new int[] { 1, 24, 4, 4, 345 };
    List<Integer>list = Ints.asList(array2);
    Collections.sort(list, comparator);
    array2 = Ints.toArray(list);

EL interprets ${class.name} as described - the name becomes getName() on the assumption you are using explicit or implicit methods of generating getter/setters

You can override this behavior by explicitly identifying the name as a function: ${class.name()} This calls the function name() directly without modification.

I needed real multithreading in Node.js and what worked for me was the threads package. It spawns another process having it's own Node.js message loop, so they don't block each other. The setup is easy and the documentation get's you up and running fast. Your main program and the workers can communicate in both ways and worker "threads" can be killed if needed.

Since multithreading and Node.js is a complicated and widely discussed topic it was quite difficult to find a package that works for my specific requirement. For the record these did not work for me:

• tiny-worker allowed spawning workers, but they seemed to share the same message loop (but it might be I did something wrong - threads had more documentation giving me confidence it really used multiple processes, so I kept going until it worked)
• webworker-threads didn't allow require-ing modules in workers which I needed

And for those asking why I needed real multi-threading: For an application involving the Raspberry Pi and interrupts. One thread is handling those interrupts and another takes care of storing the data (and more).

You cannot use CSS for this purpose. I recommend using JavaScript if it's applicable. Take a look at this for more information: JavaScript equivalent to printf/string.format

Also As Petr mentioned you can handle it on server-side but it's totally depends on your scenario.

if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then
   "nd"
else
    totext({uspRptMonthlyGasRevenueByGas;1.YearTotal},'###.00')

The above logic should be what you are looking for.

This is a quite confusing way of using Apache configuration directives.

Technically, the first bit is equivalent to

Allow From All

This is because Order Deny,Allow makes the Deny directive evaluated before the Allow Directives. In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.

Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.

The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.

Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html

However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.

It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.

The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):

#
# The following lines prevent .htaccess and .htpasswd files from being 
# viewed by Web clients. 
#
<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
    Satisfy all
</Files>

which forbids access to any file beginning by ".ht".

The equivalent Apache 2.4 configuration should look like:

<Files ~ "^\.ht">
    Require all denied
</Files>

Complete reference is not available for the mentioned files, as they are extensible by various plug-ins.

Basically, .project files store project-settings, such as builder and project nature settings, while .classpath files define the classpath to use during running. The classpath files contains src and target entries that correspond with folders in the project; the con entries are used to describe some kind of "virtual" entries, such as the JVM libs or in case of eclipse plug-ins dependencies (normal Java project dependencies are displayed differently, using a special src entry).

Deferred promises are a nice way to chain together function execution neatly and easily. Whether AJAX or normal functions, they offer greater flexibility than callbacks, and I've found easier to grasp.

function Typer()
{
var dfd = $.Deferred();
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];

UPDATE :

////////////////////////////////

  var timer=    setInterval(function() {
                    if(i == srcText.length) {

    // clearInterval(this);


       clearInterval(timer);

////////////////////////////////


   dfd.resolve();
                        };
                        i++;
                        result += srcText[i].replace("\n", "<br />");
                        $("#message").html( result);
                },
                100);
              return dfd.promise();
            }

I've modified the play function so it returns a promise when the audio finishes playing, which might be useful to some. The third function fires when sound finishes playing.

   function playBGM()
    {
      var playsound = $.Deferred();
      $('#bgm')[0].play();
      $("#bgm").on("ended", function() {
         playsound.resolve();
      });
        return playsound.promise();
    }


    function thirdFunction() {
        alert('third function');
    }

Now call the whole thing with the following: (be sure to use Jquery 1.9.1 or above as I found that 1.7.2 executes all the functions at once, rather than waiting for each to resolve.)

Typer().then(playBGM).then(thirdFunction);  

Before today, I had no luck using deferred promises in this way, and finally have grasped it. Precisely timed, chained interface events occurring exactly when we want them to, including async events, has never been easy. For me at least, I now have it under control thanks largely to others asking questions here.

The newest release of Git Extensions supports Visual Studio 2010 now (along with Visual Studio 2008 and Visual Studio 2005).

I found it to be fairly easy to use with Visual Studio 2008 and the interface seems to be the same in Visual Studio 2010.

ConcurrentHashMap allows concurrent access to data. Whole map is divided into segments.

Read operation ie. get(Object key) is not synchronized even at segment level.

But write operations ie. remove(Object key), get(Object key) acquire lock at segment level. Only part of whole map is locked, other threads still can read values from various segments except locked one.

SynchronizedMap on the other hand, acquire lock at object level. All threads should wait for current thread irrespective of operation(Read/Write).

If the difference between endTime and startTime is greater than or equal to 60 Minutes , the statement:endTime.Subtract(startTime).Minutes; will always return (minutesDifference % 60). Obviously which is not desired when we are only talking about minutes (not hours here).
Here are some of the ways if you want to get total number of minutes(in different typecasts):

// Default value that is returned is of type *double* 
double double_minutes = endTime.Subtract(startTime).TotalMinutes; 
int integer_minutes = (int)endTime.Subtract(startTime).TotalMinutes; 
long long_minutes = (long)endTime.Subtract(startTime).TotalMinutes; 
string string_minutes = (string)endTime.Subtract(startTime).TotalMinutes; 

I have come to opinion that the question is the best answer :)

import json
from urllib.request import urlopen

response = urlopen("site.com/api/foo/bar").read().decode('utf8')
obj = json.loads(response)

The state you save at onSaveInstanceState() is later available at onCreate() method invocation. So use onCreate (and its Bundle parameter) to restore state of your activity.

You can download in the various way you can follow my way. Though files may not download due to 'allow-popups' permission is not set but in your environment, this will work perfectly

<div className="col-6">_x000D_

                </div>

another one this one will also fail due to 'X-Frame-Options' to 'sameorigin'.

Further to PhoneixS answer to get the correct length of string in bytes - Since mb_strlen() is slower than strlen(), for the best performance one can check "mbstring.func_overload" ini setting so that mb_strlen() is used only when it is really required:

$content_length = ini_get('mbstring.func_overload') ? mb_strlen($content , '8bit') : strlen($content);

Prior to working on Stack Overflow, I was against NOLOCK on the principal that you could potentially perform a SELECT with NOLOCK and get back results with data that may be out of date or inconsistent. A factor to think about is how many records may be inserted/updated at the same time another process may be selecting data from the same table. If this happens a lot then there's a high probability of deadlocks unless you use a database mode such as READ COMMITED SNAPSHOT.

I have since changed my perspective on the use of NOLOCK after witnessing how it can improve SELECT performance as well as eliminate deadlocks on a massively loaded SQL Server. There are times that you may not care that your data isn't exactly 100% committed and you need results back quickly even though they may be out of date.

Ask yourself a question when thinking of using NOLOCK:

Does my query include a table that has a high number of INSERT/UPDATE commands and do I care if the data returned from a query may be missing these changes at a given moment?

If the answer is no, then use NOLOCK to improve performance.

Python threads cannot take advantage of many cores. This is due to an internal implementation detail called the GIL (global interpreter lock) in the C implementation of python (cPython) which is almost certainly what you use.

The workaround is the multiprocessing module http://www.python.org/dev/peps/pep-0371/ which was developed for this purpose.

Documentation: http://docs.python.org/library/multiprocessing.html

(Or use a parallel language.)

Use setMaxDate().

For example, replace return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay) statement with something like this:

    DatePickerDialog dialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
    dialog.getDatePicker().setMaxDate(new Date().getTime());
    return dialog;

To close your current window using JS, do this. First open the current window to trick your current tab into thinking it has been opened by a script. Then close it using window.close(). The below script should go into the parent window, not the child window. You could run this after running the script to open the child.

<script type="text/javascript">
    window.open('','_parent',''); 
    window.close();
</script>

This can be achieved with the onresize property of the GlobalEventHandlers interface in JavaScript, by assigning a function to the onresize property, like so:

window.onresize = functionRef;

The following code snippet demonstrates this, by console logging the innerWidth and innerHeight of the window whenever it's resized. (The resize event fires after the window has been resized)

function resize() {_x000D_
  console.log("height: ", window.innerHeight, "px");_x000D_
  console.log("width: ", window.innerWidth, "px");_x000D_
}_x000D_
_x000D_
window.onresize = resize;

<p>In order for this code snippet to work as intended, you will need to either shrink your browser window down to the size of this code snippet, or fullscreen this code snippet and resize from there.</p>

I just wonder why no one has mentioned Attribute classes as a declarative programming tool in C#. The popular answer of this page has just talked about LINQ as a declarative programming tool.

According to Wikipedia

Common declarative languages include those of database query languages (e.g., SQL, XQuery), regular expressions, logic programming, functional programming, and configuration management systems.

So LINQ, as a functional syntax, is definitely a declarative method, but Attribute classes in C#, as a configuration tool, are declarative too. Here is a good starting point to read more about it: Quick Overview of C# Attribute Programming

Encapsulation is hiding information.

Abstraction is hiding the functionality details.

Encapsulation is performed by constructing the class. Abstraction is achieved by creating either Abstract Classes or Interfaces on top of your class.

In the example given in the question, we are using the class for its functionality and we don't care about how the device achieves that. So we can say the details of the phone are "abstracted" from us.

Encapsulation is hiding WHAT THE PHONE USES to achieve whatever it does; Abstraction is hiding HOW IT DOES it.-

You can use the BS Typeahead fork which supports ajax calls. Then you will be able to write:

$('.typeahead').typeahead({
    source: function (typeahead, query) {
        return $.get('/typeahead', { query: query }, function (data) {
            return typeahead.process(data);
        });
    }
});

You are trying to insert data that is larger than allowed for the column logo.

Use following data types as per your need

TINYBLOB   :     maximum length of 255 bytes  
BLOB       :     maximum length of 65,535 bytes  
MEDIUMBLOB :     maximum length of 16,777,215 bytes  
LONGBLOB   :     maximum length of 4,294,967,295 bytes  

Use LONGBLOB to avoid this exception.

The original order is in fact backwards. Certs should be followed by the issuing cert until the last cert is issued by a known root per IETF's RFC 5246 Section 7.4.2

This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it.

See also SSL: error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch for troubleshooting techniques.

But I still don't know why they wrote the spec so that the order matters.

In your controller, you are using an http scheme, but I think you should be using a ws scheme, as you are using websockets. Try to use ws://localhost:3000 in your connect function.

The above answers are all cool. I found it easy to json serialize the object and deserialize as a dictionary.

var json = JsonConvert.SerializeObject(obj);
var dictionary = JsonConvert.DeserializeObject<Dictionary<string, string>>(json);

I don't know how performance is effected but this is much easier to read. You could also wrap it inside a function.

public static Dictionary<string, TValue> ToDictionary<TValue>(object obj)
{       
    var json = JsonConvert.SerializeObject(obj);
    var dictionary = JsonConvert.DeserializeObject<Dictionary<string, TValue>>(json);   
    return dictionary;
}

Use like so:

var obj = new { foo = 12345, boo = true };
var dictionary = ToDictionary<string>(obj);

Change div to span. And space the icons using   HTML

 <div class="nav3" style="height:705px;">
 <span class="icons"><a href="http://www.facebook.com/"><img src="images/facebook.png"></a>
 </span>&nbsp;&nbsp;&nbsp;
 <span class="icons"><a href="https://twitter.com"><img src="images/twitter.png"></a>
 </span>
 </div>

CSS

.nav3 {
background-color: #E9E8C7;
height: auto;
width: 150px;
float: left;
padding-left: 20px;
font-family: Arial, Helvetica, sans-serif;
font-size: 12px;
color: #333333;
padding-top: 20px;
padding-right: 20px;
}

.icons{
display:inline-block;
width: 64px; 
height: 64px; 
}

 a.icons:hover {
 background: #C93;
 }

span does not break line, div does.

I had much issues with this one too. I finally found out what's the final deal.

Referring to @Gokhan Oner answer, once you've got your Service class and the POJO representing your object, your YAML config file nice and lean, if you use the annotation @ConfigurationProperties, you have to explicitly get the object for being able to use it. Like :

@ConfigurationProperties(prefix = "available-payment-channels-list")
//@Configuration  <-  you don't specificly need this, instead you're doing something else
public class AvailableChannelsConfiguration {

    private String xyz;
    //initialize arraylist
    private List<ChannelConfiguration> channelConfigurations = new ArrayList<>();

    public AvailableChannelsConfiguration() {
        for(ChannelConfiguration current : this.getChannelConfigurations()) {
            System.out.println(current.getName()); //TADAAA
        }
    }

    public List<ChannelConfiguration> getChannelConfigurations() {
        return this.channelConfigurations;
    }

    public static class ChannelConfiguration {
        private String name;
        private String companyBankAccount;
    }

}

And then here you go. It's simple as hell, but we have to know that we must call the object getter. I was waiting at initialization, wishing the object was being built with the value but no. Hope it helps :)

The difference is that on the

foreach($featured as $key => $value){
 echo $value['name'];
}

you are able to manipulate the value of each iteration's $key from their key-value pair. Like @djiango answered, if you are not manipulating each value's $key, the result of the loop will be exactly the same as

foreach($featured as $value) {
  echo $value['name']
}

Source: You can read it from the PHP Documentation:

The first form loops over the array given by array_expression. On each iteration, the value >of the current element is assigned to $value and the internal array pointer is advanced by >one (so on the next iteration, you'll be looking at the next element).*

The second form will additionally assign the current element's key to the $key variable on >each iteration.

If the data you are manipulating is, say, arrays with custom keys, you could print them to screen like so:

$array = ("name" => "Paul", "age" => 23);

foreach($featured as $key => $value){
 echo $key . "->" . $value;
}

Should print:

name->Paul

age->23

And you wouldn't be able to do that with a foreach($featured as $value) with the same ease. So consider the format above a convenient way to manipulate keys when needed.

Cheers

    templates/

This probably indicates a misconfiguration elsewhere, but I couldn't figure out what that was and this worked.

A tested and simple solution

I've been looking for an answer for this question in SO and some other sites, but one gave an answer was very complex to me and some others answers simply doesn't work correctly, so after a lot code testing I solved this puzzle.

Note: I'm using Windows 8 and my taskbar isn't on auto-hide mode.

I discovered that setting the WindowState to Normal before performing any modifications will stop the error with the not covered taskbar.

The code

I created this class that have two methods, the first enters in the "full screen mode" and the second leaves the "full screen mode". So you just need to create an object of this class and pass the Form you want to set full screen as an argument to the EnterFullScreenMode method or to the LeaveFullScreenMode method:

class FullScreen
{
    public void EnterFullScreenMode(Form targetForm)
    {
        targetForm.WindowState = FormWindowState.Normal;
        targetForm.FormBorderStyle = FormBorderStyle.None;
        targetForm.WindowState = FormWindowState.Maximized;
    }

    public void LeaveFullScreenMode(Form targetForm)
    {
        targetForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Sizable;
        targetForm.WindowState = FormWindowState.Normal;
    }
}

Usage example

    private void fullScreenToolStripMenuItem_Click(object sender, EventArgs e)
    {
        FullScreen fullScreen = new FullScreen();

        if (fullScreenMode == FullScreenMode.No)  // FullScreenMode is an enum
        {
            fullScreen.EnterFullScreenMode(this);
            fullScreenMode = FullScreenMode.Yes;
        }
        else
        {
            fullScreen.LeaveFullScreenMode(this);
            fullScreenMode = FullScreenMode.No;
        }
    }

I have placed this same answer on another question that I'm not sure if is a duplicate or not of this one. (Link to the other question: How do I make a WinForms app go Full Screen)

SELECT CONVERT(varchar(11),Getdate(),105)

Here is a generic example of using a weak reference and static handler class to resolve the problem (as recommended in the Lint documentation):

public class MyClass{

  //static inner class doesn't hold an implicit reference to the outer class
  private static class MyHandler extends Handler {
    //Using a weak reference means you won't prevent garbage collection
    private final WeakReference<MyClass> myClassWeakReference; 

    public MyHandler(MyClass myClassInstance) {
      myClassWeakReference = new WeakReference<MyClass>(myClassInstance);
    }

    @Override
    public void handleMessage(Message msg) {
      MyClass myClass = myClassWeakReference.get();
      if (myClass != null) {
        ...do work here...
      }
    }
  }

  /**
   * An example getter to provide it to some external class
   * or just use 'new MyHandler(this)' if you are using it internally.
   * If you only use it internally you might even want it as final member:
   * private final MyHandler mHandler = new MyHandler(this);
   */
  public Handler getHandler() {
    return new MyHandler(this);
  }
}

In Swift3, I have used in this way

var hasAddedGeofencesAtleastOnce: Bool {
    get {
        return UserDefaults.standard.object(forKey: "hasAddedGeofencesAtleastOnce") != nil
    }
}

The answer is great if you are to use that multiple times.

I hope it helps :)

its solved. Use nuget and search for the "ODP.NET, Managed Driver" invariant="Oracle.ManagedDataAccess.Client".

and install the package. it will resolve the issue for me.

You can do this:

While that would be more elegant, it's possibly not as efficient as some of the other answers here.

I found a article about Logical vs Physical Address in Operating System, which clearly explains about this.

Logical Address is generated by CPU while a program is running. The logical address is virtual address as it does not exist physically therefore it is also known as Virtual Address. This address is used as a reference to access the physical memory location by CPU. The term Logical Address Space is used for the set of all logical addresses generated by a programs perspective. The hardware device called Memory-Management Unit is used for mapping logical address to its corresponding physical address.

Physical Address identifies a physical location of required data in a memory. The user never directly deals with the physical address but can access by its corresponding logical address. The user program generates the logical address and thinks that the program is running in this logical address but the program needs physical memory for its execution therefore the logical address must be mapped to the physical address bu MMU before they are used. The term Physical Address Space is used for all physical addresses corresponding to the logical addresses in a Logical address space.

To see what version you have on your Mac(Window also can run that code.), run react-native -v and you should get something like this:

If you want to know what version your project is running, look in /node_modules/react-native/package.json and look for the version key:

First try this, as others have said:

git submodule update --init

If that doesn't work, change to the submodule directory and use the following command to see if there are any changes to the submodule:

git status

If there are changes to your submodule, get rid of them. Verify that you can don't see any changes when you run "git status".

Next, go back to the main repository and run "git submodule update --init" again.

constructor(private activatedRoute: ActivatedRoute) {

this.activatedRoute.queryParams.subscribe(params => {
  console.log(params['type'])
  });  }

This works for me!

Methods for finding prime numbers are recursive. Useful for generating hash keys, for various encryption schemes that use factors of large numbers.

I had the same problem. In my case I was trying to update the primary key, which is not allowed.

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

Try the following:

   DateTime dtStart;
   DateTime dtEnd;

   if (DateTime.TryParse( tb1.Text, out dtStart ) && DateTime.TryParse(tb2.Text, out dtEnd ))
   {
      TimeSpan ts = dtStart - dtEnd;
      double difference = ts.TotalMilliseconds;
   }

You have no combinator (space, >, +...) so no children will get involved, ever.

However, you could avoid the need for jQuery by using an ID and getElementById, or you could use the old getElementsByName("frmSave")[0] or the even older document.forms['frmSave']. jQuery is unnecessary here.

Since mobile doesn't give hover feedback, I want, as a user, to see instant feedback when a link is tapped. I noticed that -webkit-tap-highlight-color is the fastest to respond (subjective).

Add the following to your body and your links will have a tap effect.

body {
    -webkit-tap-highlight-color: #ccc;
}

I had the same issue when my server free disk space available was 0

You can use the command (there must be ample space for the mysql files)

REPAIR TABLE `<table name>`;

for repairing individual tables

To send mail using Gmail SMTP, need to change your account setting. Login into your gmail accout then follow the link below to change your gmail account setting to send mail using your apps and program. https://www.google.com/settings/security/lesssecureapps

Note: This setting is not available for accounts with 2-Step Verification enabled. Such accounts require an application-specific password for less secure apps access.

Prior to adding the Ajax.BeginForm. Add below scripts to your project in the order mentioned,

1. jquery-1.7.1.min.js
2. jquery.unobtrusive-ajax.min.js

Only these two are enough for performing Ajax operation.

Depends on what you want to do with it I guess. If you just want to write some normal text you can use .fillText().

To force git stash pop run this command

git stash show -p | git apply && git stash drop

And if someone think it could help. Here is @Daniel Vérité's function, with another param that accept names of columns that can be used in search. This way it decrease the time of processing. At least in my test it reduced a lot.

CREATE OR REPLACE FUNCTION search_columns(
    needle text,
    haystack_columns name[] default '{}',
    haystack_tables name[] default '{}',
    haystack_schema name[] default '{public}'
)
RETURNS table(schemaname text, tablename text, columnname text, rowctid text)
AS $$
begin
  FOR schemaname,tablename,columnname IN
      SELECT c.table_schema,c.table_name,c.column_name
      FROM information_schema.columns c
      JOIN information_schema.tables t ON
        (t.table_name=c.table_name AND t.table_schema=c.table_schema)
      WHERE (c.table_name=ANY(haystack_tables) OR haystack_tables='{}')
        AND c.table_schema=ANY(haystack_schema)
        AND (c.column_name=ANY(haystack_columns) OR haystack_columns='{}')
        AND t.table_type='BASE TABLE'
  LOOP
    EXECUTE format('SELECT ctid FROM %I.%I WHERE cast(%I as text)=%L',
       schemaname,
       tablename,
       columnname,
       needle
    ) INTO rowctid;
    IF rowctid is not null THEN
      RETURN NEXT;
    END IF;
 END LOOP;
END;
$$ language plpgsql;

Bellow is an example of usage of the search_function created above.

SELECT * FROM search_columns('86192700'
    , array(SELECT DISTINCT a.column_name::name FROM information_schema.columns AS a
            INNER JOIN information_schema.tables as b ON (b.table_catalog = a.table_catalog AND b.table_schema = a.table_schema AND b.table_name = a.table_name)
        WHERE 
            a.column_name iLIKE '%cep%' 
            AND b.table_type = 'BASE TABLE'
            AND b.table_schema = 'public'
    )

    , array(SELECT b.table_name::name FROM information_schema.columns AS a
            INNER JOIN information_schema.tables as b ON (b.table_catalog = a.table_catalog AND b.table_schema = a.table_schema AND b.table_name = a.table_name)
        WHERE 
            a.column_name iLIKE '%cep%' 
            AND b.table_type = 'BASE TABLE'
            AND b.table_schema = 'public')
);

I'm using Argos reporting system as a front end and Oracle in back. I just encountered this error and it was caused by a string with a double quote at the start and a single quote at the end. Replacing the double quote with a single solved the issue.

For those of you who use ASP.net with VB razor the ternary operator is also possible.

It must be, as well, inside a razor expression:

@(Razor_Expression)

and the ternary operator works as follows:

If(BooleanTestExpression, "TruePart", "FalsePart")

The same code example shown here with VB razor looks like this:

<a class="@(If(User.Identity.IsAuthenticated, "auth", "anon"))">My link here</a>

Note: when writing a TextExpression remember that Boolean symbols are not the same between C# and VB.

1. First delete table

2. go to SQL

Use this code:

CREATE  TABLE service( --tablename 
  `serviceid` int(11) NOT NULL,--columns
  `customerid` varchar(20) DEFAULT NULL,--columns
  `dos` varchar(30) NOT NULL,--columns
  `productname` varchar(150) NOT NULL,--columns
  `modelnumber` bigint(12) NOT NULL,--columns
  `serialnumber` bigint(20) NOT NULL,--columns
  `serviceby` varchar(20) DEFAULT NULL--columns
)
--INSERT VALUES
INSERT INTO `service` (`serviceid`, `customerid`, `dos`, `productname`, `modelnumber`, `serialnumber`, `serviceby`) VALUES
(1, '1', '12/10/2018', 'mouse', 1234555, 234234324, '9999'),
(2, '09', '12/10/2018', 'vhbgj', 79746385, 18923984, '9999'),
(3, '23', '12/10/2018', 'mouse', 123455534, 11111123, '9999'),
(4, '23', '12/10/2018', 'mouse', 12345, 84848, '9999'),
(5, '546456', '12/10/2018', 'ughg', 772882, 457283, '9999'),
(6, '23', '12/10/2018', 'keyboard', 7878787878, 22222, '1'),
(7, '23', '12/10/2018', 'java', 11, 98908, '9999'),
(8, '128', '12/10/2018', 'mouse', 9912280626, 111111, '9999'),
(9, '23', '15/10/2018', 'hg', 29829354, 4564564646, '9999'),
(10, '12', '15/10/2018', '2', 5256, 888888, '9999');
--before droping table
ALTER TABLE `service`
  ADD PRIMARY KEY (`serviceid`),
  ADD  unique`modelnumber` (`modelnumber`),
  ADD  unique`serialnumber` (`serialnumber`),
  ADD unique`modelnumber_2` (`modelnumber`);
--after droping table
ALTER TABLE `service`
  ADD PRIMARY KEY (`serviceid`),
  ADD  modelnumber` (`modelnumber`),
  ADD  serialnumber` (`serialnumber`),
  ADD modelnumber_2` (`modelnumber`);

System.out.println(String.format("%-20s= %s" , "label", "content" ));

• Where %s is a placeholder for you string.
• The '-' makes the result left-justified.
• 20 is the width of the first string

The output looks like this:

label               = content

As a reference I recommend Javadoc on formatter syntax

I tried all answers above and nothing worked. Actually, we need 3 steps from above answers together to make it work:

1. As suggested by Flavio; add CORS configuration on your bucket:

   <CORSConfiguration>
      <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
      </CORSRule>
    </CORSConfiguration>
   

2. On the image; mention crossorigin:

   <img href="abc.jpg" crossorigin="anonymous">
   

3. Are you using a CDN? If everything works fine connecting to origin server but NOT via CDN; it means you need some setting on your CDN like accept CORS headers. Exact setting depends on which CDN you are using.

Assuming you're fine with taking all of the changes in master, what you want is:

git checkout <my branch>

to switch the working tree to your branch; then:

git merge master

to merge all the changes in master with yours.

In C++ the requirements imposed on default arguments with regard to their location in parameter list are as follows:

1. Default argument for a given parameter has to be specified no more than once. Specifying it more than once (even with the same default value) is illegal.

2. Parameters with default arguments have to form a contiguous group at the end of the parameter list.

Now, keeping that in mind, in C++ you are allowed to "grow" the set of parameters that have default arguments from one declaration of the function to the next, as long as the above requirements are continuously satisfied.

For example, you can declare a function with no default arguments

void foo(int a, int b);

In order to call that function after such declaration you'll have to specify both arguments explicitly.

Later (further down) in the same translation unit, you can re-declare it again, but this time with one default argument

void foo(int a, int b = 5);

and from this point on you can call it with just one explicit argument.

Further down you can re-declare it yet again adding one more default argument

void foo(int a = 1, int b);

and from this point on you can call it with no explicit arguments.

The full example might look as follows

void foo(int a, int b);

int main()
{
  foo(2, 3);

  void foo(int a, int b = 5); // redeclare
  foo(8); // OK, calls `foo(8, 5)`

  void foo(int a = 1, int b); // redeclare again
  foo(); // OK, calls `foo(1, 5)`
}

void foo(int a, int b)
{
  // ...
}

As for the code in your question, both variants are perfectly valid, but they mean different things. The first variant declares a default argument for the second parameter right away. The second variant initially declares your function with no default arguments and then adds one for the second parameter.

The net effect of both of your declarations (i.e. the way it is seen by the code that follows the second declaration) is exactly the same: the function has default argument for its second parameter. However, if you manage to squeeze some code between the first and the second declarations, these two variants will behave differently. In the second variant the function has no default arguments between the declarations, so you'll have to specify both arguments explicitly.

For me, no combination of window.requestAnimationFrame or setTimeout produced consistent results. Sometimes it worked, but not always—or sometimes it would be too late.

I fixed it by looping window.requestAnimationFrame as many times as necessary.
(Typically 0 or 2-3 times)

The key is diff > 0: here we can ensure exactly when the page updates.

// Ensure new image was loaded before scrolling
if (oldH > 0 && images.length > prevState.images.length) {
    (function scroll() {
        const newH = ref.scrollHeight;
        const diff = newH - oldH;

        if (diff > 0) {
            const newPos = top + diff;
            window.scrollTo(0, newPos);
        } else {
            window.requestAnimationFrame(scroll);
        }
    }());
}

I am afraid the daemon module mentioned by @Dustin didn't work for me. Instead I installed python-daemon and used the following code:

# filename myDaemon.py
import sys
import daemon
sys.path.append('/home/ubuntu/samplemodule') # till __init__.py
from samplemodule import moduleclass 

with daemon.DaemonContext():
    moduleclass.do_running() # I have do_running() function and whatever I was doing in __main__() in module.py I copied in it.

Running is easy

> python myDaemon.py

just for completeness here is samplemodule directory content

>ls samplemodule
__init__.py __init__.pyc moduleclass.py

The content of moduleclass.py can be

class moduleclass():
    ...

def do_running():
    m = moduleclass()
    # do whatever daemon is required to do.

m/ /g just give space in / /, and it will work. Or use \S — it will replace all the special characters like tab, newlines, spaces, and so on.

Instead, you simply JOIN to both tables, and in your SELECT clause, return data from the one that matches:

I suggest you to go through this link Conditional Joins in SQL Server and T-SQL Case Statement in a JOIN ON Clause

e.g.

    SELECT  *
FROM    sys.indexes i
        JOIN sys.partitions p
            ON i.index_id = p.index_id 
        JOIN sys.allocation_units a
            ON a.container_id =
            CASE
               WHEN a.type IN (1, 3)
                   THEN  p.hobt_id 
               WHEN a.type IN (2)
                   THEN p.partition_id
               END 

Edit: As per comments.

You can not specify the join condition as you are doing.. Check the query above that have no error. I have take out the common column up and the right column value will be evaluated on condition.

Adding to the above answers. Had to do one more step on Windows for git to be able to use ssh-agent.

Had to run the following command in powershell to update the environment variable:

PS> [Environment]::SetEnvironmentVariable("GIT_SSH", "$((Get-Command ssh).Source)", [System.EnvironmentVariableTarget]::User)

Restart VSCode, Powershell or whatever terminal you are using to activate the env variable.

Complete instructions can be found [here] (https://snowdrift.tech/cli/ssh/git/tutorials/2019/01/31/using-ssh-agent-git-windows.html).

The problem here is that you have defined ID as a field in your data file when what you want is to just use an expression without any data from the data file. You can fix this by defining ID as an expression (or a sequence in this case)

ID EXPRESSION "ID_SEQ.nextval"

or

ID SEQUENCE(count)

See: http://docs.oracle.com/cd/B28359_01/server.111/b28319/ldr_field_list.htm#i1008234 for all options

I was executing a get request an also want to see just the response and nothing else, seems like magic is done with -silent,-s option.

From the curl man page:

-s, --silent Silent or quiet mode. Don't show progress meter or error messages. Makes Curl mute. It will still output the data you ask for, potentially even to the terminal/stdout unless you redirect it.

Below the examples:

curl -s "http://host:8080/some/resource"
curl -silent "http://host:8080/some/resource"

Using custom headers

curl -s -H "Accept: application/json" "http://host:8080/some/resource")

Using POST method with a header

curl -s -X POST -H "Content-Type: application/json" "http://host:8080/some/resource") -d '{ "myBean": {"property": "value"}}'

You can also customize the output for specific values with -w, below the options I use to get just response codes of the curl:

curl -s -o /dev/null -w "%{http_code}" "http://host:8080/some/resource"

Use the password_verify() function

if (password_vertify($inputpassword, $row['password'])) {
  print "Logged in";
else {
    print "Password Incorrect";
}

Xcode 4.3.2 didn't install "Command Line Tools" by default. I had to open Xcode Preferences / Downloads / Components Tab. It had a list of optional components with an "Install" button beside each. This includes "Command Line Tools" and components to support developing for older versions of iOS.

Now "make" is available and you can check by opening terminal and typing:make -v

The result should look like:GNU Make 3.81

You may need "make" even if you don't need Xcode, such as a Perl developer installing Perl Modules using cpan -i on the commandline.

add the jar to WEB-INF/lib from file structure refresh the project, you should see the jar now visible under the WEB-INF/lib folder.

this is the best solution that worked for me

An API is ready-made source code library.

In Java for example APIs are a set of related classes and interfaces that come in packages. This picture illustrates the libraries included in the Java Standard Edition API. Packages are denoted by their color.

I used the QueryBuilder to get the data,

$query=$this->dm->createQueryBuilder('AppBundle:DocumentName')
             ->field('fieldName')->notEqual(null);

$data=$query->getQuery()->execute();

Adding an answer more complete example over a previous answer

<property name="propB_" value="${propA}"/>
<loadresource property="propB">
  <propertyresource name="propB_" />
  <filterchain>
    <tokenfilter>
      <replaceregex pattern="\." replace="/" flags="g"/>
    </tokenfilter>
  </filterchain>
</loadresource>

According to W3's "HTML and URLs" they should:

There may be URLs, or parts of URLs, where case doesn't matter, but identifying these may not be easy. Users should always consider that URLs are case-sensitive.

I used below piece of code. Here dragAndDrop(x,y) is a method of Action class. Which takes two parameters (x,y), source location, and target location respectively

try {
                System.out.println("Drag and Drom started :");
                Thread.sleep(12000);
                Actions actions = new Actions(webdriver);
                WebElement srcElement = webdriver.findElement(By.xpath("source Xpath"));
                WebElement targetElement = webdriver.findElement(By.xpath("Target Xpath"));
                actions.dragAndDrop(srcElement, targetElement); 
                actions.build().perform();
                System.out.println("Drag and Drom complated :");
            } catch (Exception e) {
                System.out.println(e.getMessage());
                resultDetails.setFlag(true);
            }

I do not know if it's what you were looking for, but it sounds to me something like this.

This is for linux (ubuntu) but maybe it also works on mac:

If the file is a pdf called 'book.pdf' and is located in your downloads, then

import subprocess

path='/home/user/Downloads/book.pdf'
subprocess.call(['evince', path])

where evince is the program that open pdfs in ubuntu

In general, use an index on a column that's going to be used (a lot) to search the table, such as a primary key (which by default has a clustered index). For example, if you have the query (in pseudocode)

SELECT * FROM FOO WHERE FOO.BAR = 2

You might want to put an index on FOO.BAR. A clustered index should be used on a column that will be used for sorting. A clustered index is used to sort the rows on disk, so you can only have one per table. For example if you have the query

SELECT * FROM FOO ORDER BY FOO.BAR ASCENDING

You might want to consider a clustered index on FOO.BAR.

Probably the most important consideration is how much time your queries are taking. If a query doesn't take much time or isn't used very often, it may not be worth adding indexes. As always, profile first, then optimize. SQL Server Studio can give you suggestions on where to optimize, and MSDN has some information1 that you might find useful

@ECHO OFF
SETLOCAL
set file=C:\Users\l72rugschiri\Desktop\fs.cfg
FOR %%i IN ("%file%") DO (
ECHO filedrive=%%~di
ECHO filepath=%%~pi
ECHO filename=%%~ni
ECHO fileextension=%%~xi
)

Not really sure what you mean by no "function"

Obviously, change ECHO to SET to set the variables rather thon ECHOing them...

See for documentation for a full list.

ceztko's test case (for reference)

@ECHO OFF
SETLOCAL
set file="C:\Users\ l72rugschiri\Desktop\fs.cfg"
FOR /F "delims=" %%i IN ("%file%") DO (
ECHO filedrive=%%~di
ECHO filepath=%%~pi
ECHO filename=%%~ni
ECHO fileextension=%%~xi
)

Comment : please see comments.

if you have a parameter $string and want to replace it's apace to underscore(_).

$string = "Hello All.";
$newString = str_replace(' ', '_', $string);

output will be Hello_All.

It is possible to get a context from within a Fragment

Just do

public class YourFragment extends Fragment {

    public View onCreateView(@NonNull LayoutInflater inflater,
                             ViewGroup container, Bundle savedInstanceState) {
        final View root = inflater.inflate(R.layout.yout_fragment_layout, container, false);
        // get context here
        Context context = getContext();
        // do as you please with the context


        // if you decide to go with second option
        SomeViewModel someViewModel = ViewModelProviders.of(this).get(SomeViewModel.class);
        Context context = homeViewModel.getContext();
        // do as you please with the context
        return root;
    }
}

You may also attached an AndroidViewModel in the onCreateView method that implements a method that returns the application context

public class SomeViewModel extends AndroidViewModel {

    private MutableLiveData<ArrayList<String>> someMutableData;
    Context context;

    public SomeViewModel(Application application) {
        super(application);
        context = getApplication().getApplicationContext();
        someMutableData = new MutableLiveData<>();
        .
        .
     }

     public Context getContext() {
         return context
     }
  }

For me, the only thing which worked is

git diff HEAD

including the staged files, git diff --cached only shows staged files.

To split a string to an array in awk we use the function split():

 awk '{split($0, a, ":")}'
 #           ^^  ^  ^^^
 #            |  |   |
 #       string  |   delimiter
 #               |
 #               array to store the pieces

If no separator is given, it uses the FS, which defaults to the space:

$ awk '{split($0, a); print a[2]}' <<< "a:b c:d e"
c:d

We can give a separator, for example ::

$ awk '{split($0, a, ":"); print a[2]}' <<< "a:b c:d e"
b c

Which is equivalent to setting it through the FS:

$ awk -F: '{split($0, a); print a[1]}' <<< "a:b c:d e"
b c

In gawk you can also provide the separator as a regexp:

$ awk '{split($0, a, ":*"); print a[2]}' <<< "a:::b c::d e" #note multiple :
b c

And even see what the delimiter was on every step by using its fourth parameter:

$ awk '{split($0, a, ":*", sep); print a[2]; print sep[1]}' <<< "a:::b c::d e"
b c
:::

Let's quote the man page of GNU awk:

split(string, array [, fieldsep [, seps ] ])

Divide string into pieces separated by fieldsep and store the pieces in array and the separator strings in the seps array. The first piece is stored in array[1], the second piece in array[2], and so forth. The string value of the third argument, fieldsep, is a regexp describing where to split string (much as FS can be a regexp describing where to split input records). If fieldsep is omitted, the value of FS is used. split() returns the number of elements created. seps is a gawk extension, with seps[i] being the separator string between array[i] and array[i+1]. If fieldsep is a single space, then any leading whitespace goes into seps[0] and any trailing whitespace goes into seps[n], where n is the return value of split() (i.e., the number of elements in array).

You can use year() function in sql to get the year from the specified date.

Syntax:

I just had a similar problem with Error#77 on CentOS7. I was missing the softlink /etc/pki/tls/certs/ca-bundle.crt that is installed with the ca-certificates RPM.

'curl' was attempting to open this path to get the Certificate Authorities. I discovered with:

strace curl https://example.com

and saw clearly that the open failed on that link.

My fix was:

yum reinstall ca-certificates

That should setup everything again. If you have private CAs for Corporate or self-signed use make sure they are in /etc/pki/ca-trust/source/anchors so that they are re-added.

It sounds like the populate method is what your looking for. First make small change to your post schema:

var postSchema = new Schema({
    name: String,
    postedBy: {type: mongoose.Schema.Types.ObjectId, ref: 'User'},
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Then make your model:

var Post = mongoose.model('Post', postSchema);

Then, when you make your query, you can populate references like this:

Post.findOne({_id: 123})
.populate('postedBy')
.exec(function(err, post) {
    // do stuff with post
});

MongoDB needs data directory to store data. Default path is /data/db

When you start MongoDB engine, it searches this directory which is missing in your case. Solution is create this directory and assign rwx permission to user.

If you want to change the path of your data directory then you should specify it while starting mongod server like,

mongod --dbpath /data/<path> --port <port no> 

This should help you start your mongod server with custom path and port.

Regular expression to get a string between two strings in JavaScript

The most complete solution that will work in the vast majority of cases is using a capturing group with a lazy dot matching pattern. However, a dot . in JavaScript regex does not match line break characters, so, what will work in 100% cases is a [^] or [\s\S]/[\d\D]/[\w\W] constructs.

ECMAScript 2018 and newer compatible solution

In JavaScript environments supporting ECMAScript 2018, s modifier allows . to match any char including line break chars, and the regex engine supports lookbehinds of variable length. So, you may use a regex like

var result = s.match(/(?<=cow\s+).*?(?=\s+milk)/gs); // Returns multiple matches if any
// Or
var result = s.match(/(?<=cow\s*).*?(?=\s*milk)/gs); // Same but whitespaces are optional

In both cases, the current position is checked for cow with any 1/0 or more whitespaces after cow, then any 0+ chars as few as possible are matched and consumed (=added to the match value), and then milk is checked for (with any 1/0 or more whitespaces before this substring).

Scenario 1: Single-line input

This and all other scenarios below are supported by all JavaScript environments. See usage examples at the bottom of the answer.

cow (.*?) milk

cow is found first, then a space, then any 0+ chars other than line break chars, as few as possible as *? is a lazy quantifier, are captured into Group 1 and then a space with milk must follow (and those are matched and consumed, too).

Scenario 2: Multiline input

cow ([\s\S]*?) milk

Here, cow and a space are matched first, then any 0+ chars as few as possible are matched and captured into Group 1, and then a space with milk are matched.

Scenario 3: Overlapping matches

If you have a string like >>>15 text>>>67 text2>>> and you need to get 2 matches in-between >>>+number+whitespace and >>>, you can't use />>>\d+\s(.*?)>>>/g as this will only find 1 match due to the fact the >>> before 67 is already consumed upon finding the first match. You may use a positive lookahead to check for the text presence without actually "gobbling" it (i.e. appending to the match):

/>>>\d+\s(.*?)(?=>>>)/g

See the online regex demo yielding text1 and text2 as Group 1 contents found.

Also see How to get all possible overlapping matches for a string.

Performance considerations

Lazy dot matching pattern (.*?) inside regex patterns may slow down script execution if very long input is given. In many cases, unroll-the-loop technique helps to a greater extent. Trying to grab all between cow and milk from "Their\ncow\ngives\nmore\nmilk", we see that we just need to match all lines that do not start with milk, thus, instead of cow\n([\s\S]*?)\nmilk we can use:

/cow\n(.*(?:\n(?!milk$).*)*)\nmilk/gm

See the regex demo (if there can be \r\n, use /cow\r?\n(.*(?:\r?\n(?!milk$).*)*)\r?\nmilk/gm). With this small test string, the performance gain is negligible, but with very large text, you will feel the difference (especially if the lines are long and line breaks are not very numerous).

Sample regex usage in JavaScript:

_x000D_

_x000D_

//Single/First match expected: use no global modifier and access match[1]
console.log("My cow always gives milk".match(/cow (.*?) milk/)[1]);
// Multiple matches: get multiple matches with a global modifier and
// trim the results if length of leading/trailing delimiters is known
var s = "My cow always gives milk, thier cow also gives milk";
console.log(s.match(/cow (.*?) milk/g).map(function(x) {return x.substr(4,x.length-9);}));
//or use RegExp#exec inside a loop to collect all the Group 1 contents
var result = [], m, rx = /cow (.*?) milk/g;
while ((m=rx.exec(s)) !== null) {
  result.push(m[1]);
}
console.log(result);

_x000D_

_x000D_

_x000D_

Using the modern String#matchAll method

_x000D_

_x000D_

const s = "My cow always gives milk, thier cow also gives milk";
const matches = s.matchAll(/cow (.*?) milk/g);
console.log(Array.from(matches, x => x[1]));

_x000D_

_x000D_

_x000D_

dict1 = {'m': 2, 'n': 4}
dict2 = {'n': 3, 'm': 1}

Making sure that the keys are in the same order:

dict2_sorted = {i:dict2[i] for i in dict1.keys()}

keys = dict1.keys()
values = zip(dict1.values(), dict2_sorted.values())
dictionary = dict(zip(keys, values))

gives:

{'m': (2, 1), 'n': (4, 3)}

My ~/.gradle/caches/ folder was using 14G.

After using the following solution, it went from 14G to 1.7G.

$ rm -rf ~/.gradle/caches/transforms-*

That way you haven't installed pip, you installed just the easy_install i.e. setuptools.

First you should remove all the packages you installed with easy_install using (see uninstall):

easy_install -m PackageName

This includes pip if you installed it using easy_install pip.

After this you remove the setuptools following the instructions from here:

If setuptools package is found in your global site-packages directory, you may safely remove the following file/directory:

setuptools-*.egg

If setuptools is installed in some other location such as the user site directory (eg: ~/.local, ~/Library/Python or %APPDATA%), then you may safely remove the following files:

pkg_resources.py
easy_install.py
setuptools/
setuptools-*.egg-info/

There are many different things you can do when dealing with responsive tables.

I personally like this approach by Chris Coyier:

• http://css-tricks.com/responsive-data-tables/

You can find many other alternatives here:

• http://css-tricks.com/responsive-data-table-roundup/
• http://bradfrost.github.io/this-is-responsive/patterns.html#tables

If you can leverage Bootstrap and get something quickly, you can simply use the class names ".hidden-phone" and ".hidden-tablet" to hide some rows but this approach might to be the best in many cases. More info (see "Responsive utility classes"):

UPDATE: Ruby 1.9.3 Kernel#rand also accepts ranges

rand(a..b)

http://www.rubyinside.com/ruby-1-9-3-introduction-and-changes-5428.html

Converting to array may be too expensive, and it's unnecessary.

(a..b).to_a.sample

Or

[*a..b].sample

Array#sample

Standard in Ruby 1.8.7+.
Note: was named #choice in 1.8.7 and renamed in later versions.

But anyway, generating array need resources, and solution you already wrote is the best, you can do.

Oracle has two different ways of making views updatable:-

1. The view is "key preserved" with respect to what you are trying to update. This means the primary key of the underlying table is in the view and the row appears only once in the view. This means Oracle can figure out exactly which underlying table row to update OR
2. You write an instead of trigger.

I would stay away from instead-of triggers and get your code to update the underlying tables directly rather than through the view.

The pointer-events could be useful for this problem as you would be able to put a div over the arrow button, but still be able to click the arrow button.

The pointer-events css makes it possible to click through a div.

This approach will not work for IE versions older than IE11, however. You could something working in IE8 and IE9 if the element you put on top of the arrow button is an SVG element, but it will be more complicated to style the button the way you want proceeding like this.

Here a Js fiddle example: http://jsfiddle.net/e7qnqzx6/2/

  rgrp.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup radioGroup, int i) {
            switch(i) {
                case R.id.type_car:
                    num=1;
                    Toast.makeText(getApplicationContext()," Car",Toast.LENGTH_LONG).show();
                    break;
                case R.id.type_bike:
                    num=2;
                    Toast.makeText(getApplicationContext()," Bike",Toast.LENGTH_LONG).show();
                    break;
            }
        }
    });

Add your test.js file after the jQuery libraries. This way your test.js file can use the libraries.

This is worked both chrome and firefox

set value in to dropdown box.

var given = $("#anotherbox").val();
$("#HowYouKnow").text(given).attr('value', given);

I'm curious as to why you would want to do such a thing. Chances are, you should just let garbage collection do its job. In python, garbage collection is pretty deterministic. So you don't really have to worry as much about just leaving objects laying around in memory like you would in other languages (not to say that refcounting doesn't have disadvantages).

Although one thing that you should consider is a wrapper around any objects or resources you may get rid of later.

class foo(object):
    def __init__(self):
        self.some_big_object = some_resource

    def killBigObject(self):
        del some_big_object

In response to Null's addendum:

Unfortunately, I don't believe there's a way to do what you want to do the way you want to do it. Here's one way that you may wish to consider:

>>> class manager(object):
...     def __init__(self):
...             self.lookup = {}
...     def addItem(self, name, item):
...             self.lookup[name] = item
...             item.setLookup(self.lookup)
>>> class Item(object):
...     def __init__(self, name):
...             self.name = name
...     def setLookup(self, lookup):
...             self.lookup = lookup
...     def deleteSelf(self):
...             del self.lookup[self.name]
>>> man = manager()
>>> item = Item("foo")
>>> man.addItem("foo", item)
>>> man.lookup
 {'foo': <__main__.Item object at 0x81b50>}
>>> item.deleteSelf()
>>> man.lookup
 {}

It's a little bit messy, but that should give you the idea. Essentially, I don't think that tying an item's existence in the game to whether or not it's allocated in memory is a good idea. This is because the conditions for the item to be garbage collected are probably going to be different than what the conditions are for the item in the game. This way, you don't have to worry so much about that.

Here is the implementation to delete all the substrings from the given string

public static String deleteAll(String str, String pattern)
{
    for(int index = isSubstring(str, pattern); index != -1; index = isSubstring(str, pattern))
        str = deleteSubstring(str, pattern, index);

    return str;
}

public static String deleteSubstring(String str, String pattern, int index)
{
    int start_index = index;
    int end_index = start_index + pattern.length() - 1;
    int dest_index = 0;
    char[] result = new char[str.length()];


    for(int i = 0; i< str.length() - 1; i++)
        if(i < start_index || i > end_index)
            result[dest_index++] = str.charAt(i);

    return new String(result, 0, dest_index + 1);
}

The implementation of isSubstring() method is here

This is not a new question. I addresed it in comments in one SO post, and posted my alternative implementations in another post. The comments in the first post actually elucidate the performance differences between the different implementations.

Basically, which works fastest depends on what database object you use with it.

Steps for upgrading to PHP7 on CentOS 6 system. Taken from install-php-7-in-centos-6

To install latest PHP 7, you need to add EPEL and Remi repository to your CentOS 6 system

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
yum install http://rpms.remirepo.net/enterprise/remi-release-6.rpm

Now install yum-utils, a group of useful tools that enhance yum’s default package management features

yum install yum-utils

In this step, you need to enable Remi repository using yum-config-manager utility, as the default repository for installing PHP.

yum-config-manager --enable remi-php70

If you want to install PHP 7.1 or PHP 7.2 on CentOS 6, just enable it as shown.

yum-config-manager --enable remi-php71 
yum-config-manager --enable remi-php72

Then finally install PHP 7 on CentOS 6 with all necessary PHP modules using the following command.

yum install php php-mcrypt php-cli php-gd php-curl php-mysql php-ldap php-zip php-fileinfo

Double check the installed version of PHP on your system as follows.

php -V 

If you only care about files and not empty directories, this works nicely:

find /path -type f | sort -u | xargs cat | md5sum

See: http://googletesting.blogspot.com/2007/02/tott-naming-unit-tests-responsibly.html

For test method names, I personally find using verbose and self-documented names very useful (alongside Javadoc comments that further explain what the test is doing).

Remember for jQuery 1.6+ you should use the .prop() function.

$("input").prop('disabled', true);

$("input").prop('disabled', false);

const arr= [1, 2, 3]
arr.forEach(function(element){
 if(arr[arr.length-1] === element){
  console.log("Last Element")
 }
})

Though not POSIX, bash 4 has the &> operator:

command &> alloutput.txt

Like this:

$result1 = mysql_query($query1);
$result2 = mysql_query($query2);

// do something with the 2 result sets...

if ($result1)
    mysql_free_result($result1);

if ($result2)
    mysql_free_result($result2);

No, according to Apple here:

Note: You cannot install apps from the App Store in simulation environments.

Just a little addition to the answer of @dAm2k :

In addition to sudo apt-get remove --purge mysql\*

I've done a sudo apt-get remove --purge mariadb\*.

I seems that in the new release of debian (stretch), when you install mysql it install mariadb package with it.

Hope it helps.

Install

If you use homebrew (which I recommend), you can install selenium using:

brew install selenium-server-standalone

Running

updated -port port_number

To run selenium, do: selenium-server -port 4444

For more options: selenium-server -help

in IIS, highlight the machine, double-click "Request Filtering", open the "Hidden Segments" tab. "App_Data" is listed there as a restricted folder. Yes i know this thread is really old, but this is still applicable.

You have atleast 2 options

1. Use perl:

   perl -e '@T=localtime(time-86400);printf("%02d/%02d/%02d",$T[4]+1,$T[3],$T[5]+1900)'
   

2. Install GNU date (it's in the sh_utils package if I remember correctly)

   date --date yesterday "+%a %d/%m/%Y" | read dt
   echo ${dt}
   

3. Not sure if this works, but you might be able to use a negative timezone. If you use a timezone that's 24 hours before your current timezone than you can simply use date.

Nautilus can be used easily in this case.

For Fedora 16, go to File -> Connect To server, select the appropriate protocol, enter required details and simply connect, just make sure that the SSH Server is running on other side. It works great.

Edit: This is valid on Ubuntu 14.04 as well

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

You can do this in jquery by setting the attribute disabled to 'disabled'.

$(this).prop('disabled', true);

I have made a simple example http://jsfiddle.net/4gnXL/2/

It appears this issue is fixed in npm v5.4.2

https://github.com/npm/npm/issues/17979

(Scroll down to the last comment in the thread)

Update

Actually fixed in 5.6.0. There was a cross platform bug in 5.4.2 that was causing the issue to still occur.

https://github.com/npm/npm/issues/18712

Update 2

See my answer here: https://stackoverflow.com/a/53680257/1611058

npm ci is the command you should be using when installing existing projects now.

A control that is missing from the original set of WPF controls, but much used, is the NumericUpDown control. It is a neat way to get users to select a number from a fixed range, in a small area. A slider could be used, but for compact forms with little horizontal real-estate, the NumericUpDown is essential.

Solution A (via WindowsFormsHost)

You can use the Windows Forms NumericUpDown control in WPF by hosting it in a WindowsFormsHost. Pay attention that you have to include a reference to System.Windows.Forms.dll assembly.

<Window x:Class="WpfApplication61.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:wf="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms" 
        Title="MainWindow" Height="350" Width="525">
    <StackPanel>    
        <WindowsFormsHost>
            <wf:NumericUpDown/>
        </WindowsFormsHost>
...

Solution B (custom)

There are several commercial and codeplex versions around, but both involve installing 3rd party dlls and overheads to your project. Far simpler to build your own, and a aimple way to do that is with the ScrollBar.

A vertical ScrollBar with no Thumb (just the repeater buttons) is in fact just what we want. It inherits rom RangeBase, so it has all the properties we need, like Min, Max, and SmallChange (set to 1, to restrict it to Integer values)

So we change the ScrollBar ControlTemplate. First we remove the Thumb and Horizontal trigger actions. Then we group the remains into a grid and add a TextBlock for the number:

<Grid Margin="2">
    <Grid.ColumnDefinitions>
        <ColumnDefinition/>
        <ColumnDefinition />
    </Grid.ColumnDefinitions>
    <TextBlock VerticalAlignment="Center" FontSize="20" MinWidth="25" Text="{Binding Value, RelativeSource={RelativeSource TemplatedParent}}"/>
    <Grid Grid.Column="1" x:Name="GridRoot" Width="{DynamicResource {x:Static SystemParameters.VerticalScrollBarWidthKey}}" Background="{TemplateBinding Background}">
        <Grid.RowDefinitions>
            <RowDefinition MaxHeight="18"/>
            <RowDefinition Height="0.00001*"/>
            <RowDefinition MaxHeight="18"/>
        </Grid.RowDefinitions>
        <RepeatButton x:Name="DecreaseRepeat" Command="ScrollBar.LineDownCommand" Focusable="False">
            <Grid>
                <Path x:Name="DecreaseArrow" Stroke="{TemplateBinding Foreground}" StrokeThickness="1" Data="M 0 4 L 8 4 L 4 0 Z"/>
            </Grid>
        </RepeatButton>
        <RepeatButton Grid.Row="2" x:Name="IncreaseRepeat" Command="ScrollBar.LineUpCommand" Focusable="False">
            <Grid>
                <Path x:Name="IncreaseArrow" Stroke="{TemplateBinding Foreground}" StrokeThickness="1" Data="M 0 0 L 4 4 L 8 0 Z"/>
            </Grid>
        </RepeatButton>
    </Grid>
</Grid>

I am posting this answer so the topmost answer (when sorted by activity) is not one that is just plain wrong.

What is a Stacktrace?

A stacktrace is a very helpful debugging tool. It shows the call stack (meaning, the stack of functions that were called up to that point) at the time an uncaught exception was thrown (or the time the stacktrace was generated manually). This is very useful because it doesn't only show you where the error happened, but also how the program ended up in that place of the code. This leads over to the next question:

What is an Exception?

An Exception is what the runtime environment uses to tell you that an error occurred. Popular examples are NullPointerException, IndexOutOfBoundsException or ArithmeticException. Each of these are caused when you try to do something that is not possible. For example, a NullPointerException will be thrown when you try to dereference a Null-object:

Object a = null;
a.toString();                 //this line throws a NullPointerException

Object[] b = new Object[5];
System.out.println(b[10]);    //this line throws an IndexOutOfBoundsException,
                              //because b is only 5 elements long
int ia = 5;
int ib = 0;
ia = ia/ib;                   //this line throws an  ArithmeticException with the 
                              //message "/ by 0", because you are trying to
                              //divide by 0, which is not possible.

How should I deal with Stacktraces/Exceptions?

At first, find out what is causing the Exception. Try googleing the name of the exception to find out, what is the cause of that exception. Most of the time it will be caused by incorrect code. In the given examples above, all of the exceptions are caused by incorrect code. So for the NullPointerException example you could make sure that a is never null at that time. You could, for example, initialise a or include a check like this one:

if (a!=null) {
    a.toString();
}

This way, the offending line is not executed if a==null. Same goes for the other examples.

Sometimes you can't make sure that you don't get an exception. For example, if you are using a network connection in your program, you cannot stop the computer from loosing it's internet connection (e.g. you can't stop the user from disconnecting the computer's network connection). In this case the network library will probably throw an exception. Now you should catch the exception and handle it. This means, in the example with the network connection, you should try to reopen the connection or notify the user or something like that. Also, whenever you use catch, always catch only the exception you want to catch, do not use broad catch statements like catch (Exception e) that would catch all exceptions. This is very important, because otherwise you might accidentally catch the wrong exception and react in the wrong way.

try {
    Socket x = new Socket("1.1.1.1", 6789);
    x.getInputStream().read()
} catch (IOException e) {
    System.err.println("Connection could not be established, please try again later!")
}

Why should I not use catch (Exception e)?

Let's use a small example to show why you should not just catch all exceptions:

int mult(Integer a,Integer b) {
    try {
        int result = a/b
        return result;
    } catch (Exception e) {
        System.err.println("Error: Division by zero!");
        return 0;
    }
}

What this code is trying to do is to catch the ArithmeticException caused by a possible division by 0. But it also catches a possible NullPointerException that is thrown if a or b are null. This means, you might get a NullPointerException but you'll treat it as an ArithmeticException and probably do the wrong thing. In the best case you still miss that there was a NullPointerException. Stuff like that makes debugging much harder, so don't do that.

TLDR

1. Figure out what is the cause of the exception and fix it, so that it doesn't throw the exception at all.

2. If 1. is not possible, catch the specific exception and handle it.

   • Never just add a try/catch and then just ignore the exception! Don't do that!
   • Never use catch (Exception e), always catch specific Exceptions. That will save you a lot of headaches.

I think using enumerate on the outer loop and using the index to slice the list on the inner loop is pretty Pythonic:

for index, this in enumerate(mylist):
    for that in mylist[index+1:]:
        compare(this, that)

re: VMware Workstation support for physical disks vs virtual disks.

I run Player with the VM Disk files on their own dedicated fast hard drive, independent from the OS hard drive. This allows both the OS and Player to simultaneously independently read/write to their own drives, the performance difference is noticeable, and a second WD Black or Raptor or SSD is cheap. Placing the VM disk file on a second drive also works with Microsoft Virtual PC.

Slack has a cool way of making tabs small viewport friendly on some of their admin pages. I made something similar using bootstrap. It's kind of a tabs ? dropdown.

Demo: http://jsbin.com/nowuyi/1

Here's what it looks like on a big viewport:

Here's how it looks collapsed on a small viewport:

Here's how it looks expanded on a small viewport:

the HTML is exactly the same as default bootstrap tabs.

There is a small JS snippet, which requires jquery (and inserts two span elements into the DOM):

$.fn.responsiveTabs = function() {
  this.addClass('responsive-tabs');
  this.append($('<span class="glyphicon glyphicon-triangle-bottom"></span>'));
  this.append($('<span class="glyphicon glyphicon-triangle-top"></span>'));

  this.on('click', 'li.active > a, span.glyphicon', function() {
    this.toggleClass('open');
  }.bind(this));

  this.on('click', 'li:not(.active) > a', function() {
    this.removeClass('open');
  }.bind(this));
};

$('.nav.nav-tabs').responsiveTabs();

And then there is a lot of css (less):

@xs: 768px;


.responsive-tabs.nav-tabs {

  overflow: visible;

    right: 22px;
    &.glyphicon-triangle-top {
      display: none;
    }
    @media(min-width: @xs) {
      display: none;
    }
  }

  > li {
    display: none;
    float: none;
    text-align: center;

    &:last-of-type > a {
      margin-right: 0;
    }

    > a {
      margin-right: 0;
      background: #fff;
      border: 1px solid #DDDDDD;

      @media(min-width: @xs) {
        margin-right: 4px;
      }
    }

    &.active {
      display: block;
      a {
        @media(min-width: @xs) {
          border-bottom-color: transparent; 
        }
        border: 1px solid #DDDDDD;
        border-radius: 2px;
      }
    }

    @media(min-width: @xs) {
      display: block;
      float: left;
    }

  }

  &.open {

    span.glyphicon {
      &.glyphicon-triangle-top {
        display: block;
        @media(min-width: @xs) {
          display: none;
        }
      }
      &.glyphicon-triangle-bottom {
        display: none;
      }
    }

    > li {

      a {

    }
  }
}

I have encountered with same issue. When I changed content type it has solved. I'm not sure this solution will help you but maybe it is. If you don't mind about content-type, it worked for me.

axios.defaults.headers.post['Content-Type'] ='application/x-www-form-urlencoded';

I started using maven on my machine first time in while. Got this error: Could not transfer artifact from/to central (https://repo.maven.apache.org/maven2) No such file or directory Cleaned up ~/.m2/repository directory. Don't experience this problem again

Add Following methods in ViewController.m file, its working properly

    -(BOOL) canBecomeFirstResponder
    {
         /* Here, We want our view (not viewcontroller) as first responder 
         to receive shake event message  */

         return YES;
    }

    -(void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
    {
            if(event.subtype==UIEventSubtypeMotionShake)
            {
                    // Code at shake event

                    UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Motion" message:@"Phone Vibrate"delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
                    [alert show];
                    [alert release];

                    [self.view setBackgroundColor:[UIColor redColor]];
             }
    }
    - (void)viewDidAppear:(BOOL)animated
    {
             [super viewDidAppear:animated];
             [self becomeFirstResponder];  // View as first responder 
     }

To declare a string literal as an output column, leave the Table off and just use Test. It doesn't need to be associated with a table among your joins, since it will be accessed only by its column alias. When using a metadata function like getColumnMeta(), the table name will be an empty string because it isn't associated with a table.

SELECT
  `field1`, 
  `field2`, 
  'Test' AS `field3` 
FROM `Test`;

Note: I'm using single quotes above. MySQL is usually configured to honor double quotes for strings, but single quotes are more widely portable among RDBMS.

If you must have a table alias name with the literal value, you need to wrap it in a subquery with the same name as the table you want to use:

SELECT
  field1,
  field2,
  field3
FROM 
  /* subquery wraps all fields to put the literal inside a table */
  (SELECT field1, field2, 'Test' AS field3 FROM Test) AS Test

Now field3 will come in the output as Test.field3.

On Debian/Ubuntu:

First install and build dependencies of psycopg2 package:

# apt-get build-dep python-psycopg2

Then in your virtual environment, compile and install psycopg2 module:

(env)$ pip install psycopg2

This Perl one-liner comments out lines 1 to 3 of the file orig.sh inclusive (where the first line is numbered 0), and writes the commented version to cmt.sh.

perl -n -e '$s=1;$e=3; $_="#$_" if $i>=$s&&$i<=$e;print;$i++' orig.sh > cmt.sh

Obviously you can change the boundary numbers as required.

If you want to edit the file in place, it's even shorter:

perl -in -e '$s=1;$e=3; $_="#$_" if $i>=$s&&$i<=$e;print;$i++' orig.sh

Demo

$ cat orig.sh 
a
b
c
d
e
f

$ perl -n -e '$s=1;$e=3; $_="#$_" if $i>=$s&&$i<=$e;print;$i++' orig.sh > cmt.sh

$ cat cmt.sh 
a
#b
#c
#d
e
f

About the progressbar control in a userform, it won't show any progress if you don't use the repaint event. You have to code this event inside the looping (and obviously increment the progressbar value).

Example of use:

userFormName.repaint

In addition to what eugene and stevenl posted, you might encounter problems with using both <> and <STDIN> in one script: <> iterates through (=concatenating) all files given as command line arguments.

However, should a user ever forget to specify a file on the command line, it will read from STDIN, and your code will wait forever on input

Check out the help command:

svn help copy

  -r [--revision] arg      : ARG (some commands also take ARG1:ARG2 range)
                             A revision argument can be one of:
                                NUMBER       revision number
                                '{' DATE '}' revision at start of the date
                                'HEAD'       latest in repository
                                'BASE'       base rev of item's working copy
                                'COMMITTED'  last commit at or before BASE
                                'PREV'       revision just before COMMITTED

To actually specify this on the command line using your example:

svn copy -r123 http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

Where 123 would be the revision number in trunk you want to copy. As others have noted, you can also use the @ syntax. I prefer the clearer separation of the revision # from the URL, personally.

As noted in the help, you can replace a revision # with certain words as well:

svn copy -rPREV http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

Would copy the "revision just before COMMITTED".

Use a Try Catch block on your server side and in the catch block pass back the exception error to the client. This should give you a helpful error message.

Always, always, always put disposable objects inside of using statements. I can't see how you've instantiated your DataReader but you should do it like this:

using (Connection c = ...)
{
    using (DataReader dr = ...)
    {
        //Work with dr in here.
    }
}
//Now the connection and reader have been closed and disposed.

Now, to answer your question, the reader is using the same connection as the command you're trying to ExecuteNonQuery on. You need to use a separate connection since the DataReader keeps the connection open and reads data as you need it.

A simple safe way would be to use an alias. Place this into ~/.bashrc file: if you have gedit editor use

gedit ~/.bashrc

to go into the bashrc file and then at the top of the bashrc file make the following change.

alias python=python3

After adding the above in the file. run the below command

source ~/.bash_aliases or source ~/.bashrc

example:

$ python --version

Python 2.7.6

$ python3 --version

Python 3.4.3

$ alias python=python3

$ python --version

Python 3.4.3

A quick answer:

mvn -fn test

Works with nested project builds.

I like Cohens answer, but a more technical definition is: Your code calls a library. A framework calls your code. For example a GUI framework calls your code through event-handlers. A web framework calls your code through some request-response model.

This is also called inversion of control - suddenly the framework decides when and how to execute you code rather than the other way around as with libraries. This means that a framework also have a much larger impact on how you have to structure your code.
